experiment was conducted in laboratory conditions in researches of agronomy, College of agriculture, Isfahan University of Technology in 2015. A laboratory experiment was conducted on a factorial arrangement in a randomized complete design with four replications. Testing factors include two wheat cultivars (Flat and Atila -4) and three level of Lambsqua (Chenopodium album) extract (30, 60 and 90 percent) plus control with no extract. Twenty-five seeds of each wheat varieties were placed in petri dish, then the root extract of lambsqua, which was prepared previously at three levels, was poured on the seeds in each petri dish. The result showed that allelopathic effect of Lambsquarter on germination, root, and shoot dry weight of two varieties was highly significant. Among varieties, the Atila–4 showed minimum germination at 60% while the Flat showed minimum germination at 90% concentration. In case of root dry weight, Atila–4 was more suppressed as compared to Flat at 60% concentration but at 90% concentration, the both wheat varieties were reduced non-significantly. Shoot dry weight of Flat were decreased non-significantly concentrations except Atila -4 that was more reduced at 60 % than 90% concentration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=allelopathy" title="allelopathy">allelopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=Chenopodium%20album" title=" Chenopodium album"> Chenopodium album</a>, <a href="https://publications.waset.org/abstracts/search?q=extract" title=" extract"> extract</a>, <a href="https://publications.waset.org/abstracts/search?q=germination" title=" germination"> germination</a>, <a href="https://publications.waset.org/abstracts/search?q=wheat" title=" wheat"> wheat</a>, <a href="https://publications.waset.org/abstracts/search?q=early%20growth" title=" early growth"> early growth</a> </p> <a href="https://publications.waset.org/abstracts/78721/allelopathic-effects-of-lambsquarters-chenopodium-album-extract-on-the-germination-and-early-growth-of-wheat-triticum-aestivum-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78721.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">182</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">126</span> Feasibility Study of a Solar Farm Project with an Executive Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Reza%20Talaghat">Amir Reza Talaghat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since 2015, a new approach and policy regarding energy resources protection and using renewable energies has been started in Iran which was developing new projects.

Almost all infected people die or have irreversible neurological complications. Therefore, it is essential to have a diagnostic kit with the ability to quickly detect these fatal infections. The project involved 212 patients from whom cerebrospinal fluid samples were obtained. After total genome extraction and performing multiplex quantitative polymerase chain reaction (qPCR), the presence or absence of each infectious factor was determined by comparing with standard strains. The specificity, sensitivity, positive predictive value, and negative predictive value calculated were 100%, 92.9%, 50%, and 100%, respectively. So, due to the high specificity and sensitivity of the designed primers, they can be used instead of bacterial culture that takes at least 24 to 48 hours. The remarkable benefit of this method is associated with the speed (up to 3 hours) at which the procedure could be completed. It is also worth noting that this method can reduce the personnel unintentional errors which may occur in the laboratory. On the other hand, as this method simultaneously identifies four common factors that cause bacterial meningitis, it could be used as an auxiliary method diagnostic technique in laboratories particularly in cases of emergency medicine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cerebrospinal%20fluid" title="cerebrospinal fluid">cerebrospinal fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=meningitis" title=" meningitis"> meningitis</a>, <a href="https://publications.waset.org/abstracts/search?q=quantitative%20polymerase%20chain%20reaction" title=" quantitative polymerase chain reaction"> quantitative polymerase chain reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=simultaneous%20detection" title=" simultaneous detection"> simultaneous detection</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis%20testing" title=" diagnosis testing"> diagnosis testing</a> </p> <a href="https://publications.waset.org/abstracts/151315/use-of-a-new-multiplex-quantitative-polymerase-chain-reaction-based-assay-for-simultaneous-detection-of-neisseria-meningitidis-escherichia-coli-k1-streptococcus-agalactiae-and-streptococcus-pneumoniae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151315.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">115</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">124</span> Quality Evaluation of Treated Ballast Seawater for Potential Reuse</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siti%20Nur%20Muhamad">Siti Nur Muhamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Abu%20Ubaidah%20Amir"> Mohamad Abu Ubaidah Amir</a>, <a href="https://publications.waset.org/abstracts/search?q=Adenen%20Shuhada%20Abdul%20Aziz"> Adenen Shuhada Abdul Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Siti%20Sarah%20Mohd%20Isnan"> Siti Sarah Mohd Isnan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ainul%20Husna%20Abdul%20Rahman"> Ainul Husna Abdul Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Nur%20Afiqah%20Rosly"> Nur Afiqah Rosly</a>, <a href="https://publications.waset.org/abstracts/search?q=Roshamida%20Abd%20Jamil"> Roshamida Abd Jamil</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The International Convention for the Control and Management of Ships’ Ballast Water and Sediments (BWM Convention) will commencing on 8 September 2017 after ratified by 51 States in September 2016. However, there is no value recovered for the treated ballast water as it simply discharged during de-ballasting. In order to evaluate value creation of treated ballast water, three seawater applications which are seawater toilet flushing, cooling tower and desalination was studied and compared with treated ballast seawater. An exploratory study was conducted in Singapore as a case study as this country is facing water scarcity issues and a busy port in the world which received more than 28 billion m3 of ballast water in 2015. Surprisingly the treatment technology between seawater toilet flushing and ballast water management has similarity as both applications use screening and disinfection process and quality standard and analysis between treated ballast water with seawater applications found that seawater toilet flushing have the same quality parameter with treated ballast water. Thus, the treated ballast water can replace the raw seawater for seawater desalination. As such, with reduction of cost for screen unit, desalination water can exceed water production by NEWater in Singapore as the cost can recover the energy needed for desalination. It can conclude that treated ballast water has high recovery value and can be reused in seawater application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ballast%20water%20treatment" title="ballast water treatment">ballast water treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=desalination" title=" desalination"> desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=BWM%20convention" title=" BWM convention"> BWM convention</a>, <a href="https://publications.waset.org/abstracts/search?q=ballast%20water%20management" title=" ballast water management"> ballast water management</a> </p> <a href="https://publications.waset.org/abstracts/64168/quality-evaluation-of-treated-ballast-seawater-for-potential-reuse" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64168.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">378</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">123</span> The Genetic Basis of the Lack of Impulse Control: What is Provided for the Criminal Law?</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Bastani">Amir Bastani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The result of the research in the field of human behavioural genetics demonstrates a genetic contribution of behavioural differences in aggression, violence, drug and substance abuse, antisocial personality disorder and other related traits. As the field of human behavioural genetics progresses and achieves credibility, the criminal accused continue to use its types of evidence into the criminal law. One of the most important genetic factors which controls certain neurotransmitters like dopamine and serotonin is the Monoamine Oxidase Acid A (MAOA) gene, known as the 'warrior gene'. The high-profile study by Caspi and colleagues in 2002 showed that the combination between one type of variation of the MAOA gene and childhood maltreatment noticeably predisposes a person to antisocial behaviour. Moreover, further scientific research shows that individuals with the MAOA gene have to some degree difficulties in controlling their impulses. Based on the evidence of MAOA, some criminal accused claimed difficulties in self-control. In the first case – the famous case of Mobley – the court rejected the MAOA evidence on the ground of the lack of scientific support. In contrast, in other cases after the Mobley trial, courts accepted the evidence of MAOA. In this paper, the issue of lack of impulse control produced by the MAOA gene and cases which relied on the MAOA evidence and successfully being accepted will be reviewed in detail. Finally, the anticipation of the paper for the future use of the MAOA evidence in criminal cases will be presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genetic%20defence" title="genetic defence">genetic defence</a>, <a href="https://publications.waset.org/abstracts/search?q=criminal%20responsibility" title=" criminal responsibility"> criminal responsibility</a>, <a href="https://publications.waset.org/abstracts/search?q=MAOA" title=" MAOA"> MAOA</a>, <a href="https://publications.waset.org/abstracts/search?q=self-control" title=" self-control"> self-control</a> </p> <a href="https://publications.waset.org/abstracts/20503/the-genetic-basis-of-the-lack-of-impulse-control-what-is-provided-for-the-criminal-law" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20503.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">472</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">122</span> The Effect of Arbitrary Support Conditions on the Static Behavior of Curved Beams Using the Finite Element Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Mottaghi%20T.">Hossein Mottaghi T.</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20R.%20Masoodi"> Amir R.

The objective is to enhance accuracy while reducing the number of elements by incorporating first-order shear deformations of Timoshenko beams. Initially, finite element formulations are developed by considering polynomial initial functions for axial, shear, and rotational deformations for a three-node element. Subsequently, nodal interpolation functions for this element are derived, followed by the construction of the element stiffness matrix. To enable the utilization of the stiffness matrix in the static analysis of curved beams, the constructed matrix in the local coordinates of the element is transformed to the global coordinate system using the rotation matrix. A numerical benchmark example is investigated to assess the accuracy and effectiveness of this method. Moreover, the influence of spring stiffness on the rotation of the endpoint of a clamped beam is examined by substituting each support reaction of the beam with a spring. In the parametric study, the effect of the central angle of the beam on the rotation of the beam's endpoint in a cantilever beam under a concentrated load is examined. This research encompasses various mechanical, geometrical, and boundary configurations to evaluate the static characteristics of curved beams, thus providing valuable insights for their analysis and examination. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=curved%20beam" title="curved beam">curved beam</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=first-order%20shear%20deformation%20theory" title=" first-order shear deformation theory"> first-order shear deformation theory</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic%20support" title=" elastic support"> elastic support</a> </p> <a href="https://publications.waset.org/abstracts/186836/the-effect-of-arbitrary-support-conditions-on-the-static-behavior-of-curved-beams-using-the-finite-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186836.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">70</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">121</span> Catalyst Assisted Microwave Plasma for NOx Formation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Babak%20Sadeghi">Babak Sadeghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Rony%20Snyders"> Rony Snyders</a>, <a href="https://publications.waset.org/abstracts/search?q=Marie-Paule.Delplancke-Ogletree"> Marie-Paule.Delplancke-Ogletree</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nitrogen fixation (NF) is one of the crucial industrial processes. Many attempts have been made in order to artiﬁcially ﬁx nitrogen, and among them, the Haber-Bosch’s (H-B) process is widely used. However, it presents two major drawbacks: huge fossil feedstock consumption and noticeable greenhouse gases emission. It is, therefore, necessary to develop alternatives. Plasma technology, as an inherent “green” technology, is considered to have a great potential for reducing the environmental impacts and improving the energy efficiency of the NF process. In this work, we have studied the catalyst assisted microwave plasma for NF application. Heterogeneous catalysts of MoO₃, with various loads 0, 5, 10, 20, and 30 wt%, supported on γ-alumina were prepared by conventional wet impregnation. Crystallinity, surface area, pore size, and microstructure were obtained by X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) adsorption isotherm, Scanning electron microscopy (SEM), and Transmission electron microscopy (TEM). The XRD patterns of calcined alumina confirm the γ- phase. Characteristic picks of MoO₃ could not be observed for low loads (< 20 wt%), likely indicating a high dispersion of metal oxide over the support. The specific surface area along with pores size are decreasing with increasing calcination temperature and MoO₃ loading. The MoO₃ loading does not modify the microstructure. TEM and SEM results for loading inferior to 20 wt% are coherent with a monolayer of MoO₃ on the support as proposed elsewhere. For loading of 20 wt% and more, TEM and Electron diffraction (ED) show nanocrystalline ₃-D MoO₃ particles. The catalytic performances of these catalysts were investigated in the post-discharge of a microwave plasma for NOx formation from N₂/O₂ mixtures. The plasma is sustained by a surface wave launched in a quartz tube via a surfaguide supplied by a 2.45 GHz microwave generator in pulse mode. In-situ identification and quantification of the products were carried out by Fourier-transform infrared spectroscopy (FTIR) in the post-discharge region. FTIR analysis of the exhausted gas reveal NO and NO₂ bands in presence of catalyst while only NO band were assigned without catalyst. On the other hand, in presence of catalyst, a 10% increase of NOₓ formation and of 20% increase in energy efficiency are observed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=%CE%B3-Al2O%E2%82%83-MoO%E2%82%83" title="γ-Al2O₃-MoO₃">γ-Al2O₃-MoO₃</a>, <a href="https://publications.waset.org/abstracts/search?q=%C2%B5-waveplasma" title=" µ-waveplasma"> µ-waveplasma</a>, <a href="https://publications.waset.org/abstracts/search?q=N2%20fixation" title=" N2 fixation"> N2 fixation</a>, <a href="https://publications.waset.org/abstracts/search?q=Plasma-catalysis" title=" Plasma-catalysis"> Plasma-catalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Plasma%20diagnostic" title=" Plasma diagnostic"> Plasma diagnostic</a> </p> <a href="https://publications.waset.org/abstracts/139708/catalyst-assisted-microwave-plasma-for-nox-formation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139708.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">176</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">120</span> Usage the Point Analysis Algorithm (SANN) on Drought Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khosro%20Shafie%20Motlaghi">Khosro Shafie Motlaghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Reza%20Salemian"> Amir Reza Salemian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In arid and semi-arid regions like our country Evapotranspiration is the greatestportion of water resource.

Several research studies in recent years have provided evidence that cancer initiation and progression are driven by genetic alterations of the tumor and paracrine interactions between tumor and microenvironment. Scattered data show that the Endothelial and Smooth muscle cell-Derived Neuropilin-like molecule (ESDN) controls cell proliferation and movement of stroma and tumor cells. To investigate the role of ESDN in the tumor microenvironment during melanoma progression, murine melanoma cells (B16 or B16-F10) were injected in ESDN knockout mice in order to evaluate how the absence of ESDN in stromal cells could influence melanoma progression. While no effect was found on primary tumor growth, increased cell extravasation and lung metastasis formation was observed in ESDN knockout mice compared to wild type controls. In order to understand how cancer cells cross the endothelial barrier during metastatic dissemination in an ESDN-null microenvironment, structure, and permeability of lung blood vessels were analyzed. Interestingly, ESDN knockout mice showed structurally altered and more permeable vessels compared to wild type animals. Since cell surface molecules mediate the process of tumor cell extravasation, the expression of a panel of extravasation-related ligands and receptors was analyzed. Importantly, modulations of N-cadherin, E-selectin, ICAM-1 and VAP-1 were observed in ESDN knockout endothelial cells, suggesting the presence of a favorable tumor microenvironment which facilitates melanoma cell extravasation and metastasis formation in the absence of ESDN. Furthermore, a potential contribution of immune cells in tumor dissemination was investigated. An increased recruitment of macrophages in the lungs of ESDN knockout mice carrying subcutaneous B16-F10 tumors was found. In conclusion, our data suggest a functional role of ESDN in the tumor microenvironment during melanoma progression and the identification of the mechanisms that regulate tumor cell extravasation could lead to the development of new therapies to reduce metastasis formation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=melanoma" title="melanoma">melanoma</a>, <a href="https://publications.waset.org/abstracts/search?q=tumor%20microenvironment" title=" tumor microenvironment"> tumor microenvironment</a>, <a href="https://publications.waset.org/abstracts/search?q=extravasation" title=" extravasation"> extravasation</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20surface%20molecules" title=" cell surface molecules"> cell surface molecules</a> </p> <a href="https://publications.waset.org/abstracts/44830/esdn-expression-in-the-tumor-microenvironment-coordinates-melanoma-progression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44830.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">333</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">118</span> Synthesis of Multi-Functional Iron Oxide Nanoparticles for Targeted Drug Delivery in Cancer Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masome%20Moeni">Masome Moeni</a>, <a href="https://publications.waset.org/abstracts/search?q=Roya%20Abedizadeh"> Roya Abedizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Aram"> Elham Aram</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Sadeghi-Abandansari"> Hamid Sadeghi-Abandansari</a>, <a href="https://publications.waset.org/abstracts/search?q=Davood%20Sabour"> Davood Sabour</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Menzel"> Robert Menzel</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Hassanpour"> Ali Hassanpour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Significant number of studies and preclinical research in formulation of cancer nano-pharmaceutics have led to an improvement in cancer care. Nonetheless, the antineoplastic agents have ‘failed to live up to its promise’ since their clinical performance is moderately low. For almost ninety years, iron oxide nanoparticles (IONPS) have managed to keep its reputation in clinical application due to their low toxicity, versatility and multi-modal capabilities. Drug Administration approved utilization of IONPs for diagnosis of cancer as contrast media in magnetic resonance imaging, as heat mediator in magnetic hyperthermia and for the treatment of iron deficiency. Furthermore, IONPs have high drug-loading capacity, which makes them good candidates as therapeutic agent transporters. There are yet challenges to overcome for successful clinical application of IONPs, including stability of drug and poor delivery, which might lead to (i) drug resistance, (ii) shorter blood circulation time, and (iii) rapid elimination and adverse side effects from the system. In this study, highly stable and super paramagnetic IONPs were prepared for efficient and targeted drug delivery in cancer treatment. The synthesis procedure was briefly involved the production of IONPs via co-precipitation followed by coating with tetraethyl orthosilicate and 3-aminopropylethoxysilane and grafting with folic acid for stability targeted purposes and controlled drug release. Physiochemical and morphological properties of modified IONPs were characterised using different analytical techniques. The resultant IONPs exhibited clusters of 10 nm spherical shape crystals with less than 100 nm size suitable for drug delivery. The functionalized IONP showed mesoporous features, high stability, dispersibility and crystallinity. Subsequently, the functionalized IONPs were successfully loaded with oxaliplatin, a chemotherapeutic agent, for a controlled drug release in an actively targeting cancer cells. FT-IR observations confirmed presence of oxaliplatin functional groups, while ICP-MS results verified the drug loading was ~ 1.3%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer%20treatment" title="cancer treatment">cancer treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=chemotherapeutic%20agent" title=" chemotherapeutic agent"> chemotherapeutic agent</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20delivery" title=" drug delivery"> drug delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20oxide" title=" iron oxide"> iron oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-functional%20nanoparticle" title=" multi-functional nanoparticle"> multi-functional nanoparticle</a> </p> <a href="https://publications.waset.org/abstracts/166578/synthesis-of-multi-functional-iron-oxide-nanoparticles-for-targeted-drug-delivery-in-cancer-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166578.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">82</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">117</span> Over Cracking in Furnace and Corrective Action by Computational Fluid Dynamics (CFD) Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mokhtari%20Karchegani%20Amir">Mokhtari Karchegani Amir</a>, <a href="https://publications.waset.org/abstracts/search?q=Maboudi%20Samad"> Maboudi Samad</a>, <a href="https://publications.waset.org/abstracts/search?q=Azadi%20Reza"> Azadi Reza</a>, <a href="https://publications.waset.org/abstracts/search?q=Dastanian%20Raoof"> Dastanian Raoof</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Marun's petrochemical cracking furnaces have a very comprehensive operating control system for combustion and related equipment, utilizing advanced instrument circuits. However, after several years of operation, numerous problems arose in the pyrolysis furnaces. A team of experts conducted an audit, revealing that the furnaces were over-designed, leading to excessive consumption of air and fuel. This issue was related to the burners' shutter settings, which had not been configured properly. The operations department had responded by increasing the induced draft fan speed and forcing the instrument switches to counteract the wind effect in the combustion chamber. Using Fluent and Gambit software, the furnaces were analyzed. The findings indicated that this situation elevated the convection part's temperature, causing uneven heat distribution inside the furnace. Consequently, this led to overheating in the convection section and excessive cracking within the coils in the radiation section. The increased convection temperature damaged convection parts and resulted in equipment blockages downstream of the furnaces due to the production of more coke and tar in the process. To address these issues, corrective actions were implemented. The excess air for burners and combustion chambers was properly set, resulting in improved efficiency, reduced emissions of environmentally harmful gases, prevention of creep in coils, decreased fuel consumption, and lower maintenance costs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=furnace" title="furnace">furnace</a>, <a href="https://publications.waset.org/abstracts/search?q=coke" title=" coke"> coke</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD%20analysis" title=" CFD analysis"> CFD analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=over%20cracking" title=" over cracking"> over cracking</a> </p> <a href="https://publications.waset.org/abstracts/177816/over-cracking-in-furnace-and-corrective-action-by-computational-fluid-dynamics-cfd-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177816.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">77</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">116</span> Python Implementation for S1000D Applicability Depended Processing Model - SALERNO</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Theresia%20El%20Khoury">Theresia El Khoury</a>, <a href="https://publications.waset.org/abstracts/search?q=Georges%20Badr"> Georges Badr</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Hajjam%20El%20Hassani"> Amir Hajjam El Hassani</a>, <a href="https://publications.waset.org/abstracts/search?q=St%C3%A9phane%20N%E2%80%99Guyen%20Van%20Ky"> Stéphane N’Guyen Van Ky</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The widespread adoption of machine learning and artificial intelligence across different domains can be attributed to the digitization of data over several decades, resulting in vast amounts of data, types, and structures. Thus, data processing and preparation turn out to be a crucial stage. However, applying these techniques to S1000D standard-based data poses a challenge due to its complexity and the need to preserve logical information. This paper describes SALERNO, an S1000d AppLicability dEpended pRocessiNg mOdel. This python-based model analyzes and converts the XML S1000D-based files into an easier data format that can be used in machine learning techniques while preserving the different logic and relationships in files. The model parses the files in the given folder, filters them, and extracts the required information to be saved in appropriate data frames and Excel sheets. Its main idea is to group the extracted information by applicability. In addition, it extracts the full text by replacing internal and external references while maintaining the relationships between files, as well as the necessary requirements. The resulting files can then be saved in databases and used in different models. Documents in both English and French languages were tested, and special characters were decoded. Updates on the technical manuals were taken into consideration as well. The model was tested on different versions of the S1000D, and the results demonstrated its ability to effectively handle the applicability, requirements, references, and relationships across all files and on different levels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aeronautics" title="aeronautics">aeronautics</a>, <a href="https://publications.waset.org/abstracts/search?q=big%20data" title=" big data"> big data</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20processing" title=" data processing"> data processing</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=S1000D" title=" S1000D"> S1000D</a> </p> <a href="https://publications.waset.org/abstracts/164505/python-implementation-for-s1000d-applicability-depended-processing-model-salerno" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164505.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">156</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">115</span> Advanced Numerical and Analytical Methods for Assessing Concrete Sewers and Their Remaining Service Life</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Alani">Amir Alani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Mahmoodian"> Mojtaba Mahmoodian</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Romanova"> Anna Romanova</a>, <a href="https://publications.waset.org/abstracts/search?q=Asaad%20Faramarzi"> Asaad Faramarzi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pipelines are extensively used engineering structures which convey fluid from one place to another. Most of the time, pipelines are placed underground and are encumbered by soil weight and traffic loads. Corrosion of pipe material is the most common form of pipeline deterioration and should be considered in both the strength and serviceability analysis of pipes. The study in this research focuses on concrete pipes in sewage systems (concrete sewers). This research firstly investigates how to involve the effect of corrosion as a time dependent process of deterioration in the structural and failure analysis of this type of pipe. Then three probabilistic time dependent reliability analysis methods including the first passage probability theory, the gamma distributed degradation model and the Monte Carlo simulation technique are discussed and developed. Sensitivity analysis indexes which can be used to identify the most important parameters that affect pipe failure are also discussed. The reliability analysis methods developed in this paper contribute as rational tools for decision makers with regard to the strengthening and rehabilitation of existing pipelines. The results can be used to obtain a cost-effective strategy for the management of the sewer system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reliability%20analysis" title="reliability analysis">reliability analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=service%20life%20prediction" title=" service life prediction"> service life prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=Monte%20Carlo%20simulation%20method" title=" Monte Carlo simulation method"> Monte Carlo simulation method</a>, <a href="https://publications.waset.org/abstracts/search?q=first%20passage%20probability%20theory" title=" first passage probability theory"> first passage probability theory</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma%20distributed%20degradation%20model" title=" gamma distributed degradation model"> gamma distributed degradation model</a> </p> <a href="https://publications.waset.org/abstracts/9271/advanced-numerical-and-analytical-methods-for-assessing-concrete-sewers-and-their-remaining-service-life" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9271.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">456</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">114</span> Investigating the relationship between Emotional Intelligence of principals in high schools(secondary school principals) and Teachers Conflict Management: A Case Study on secondary schools, Tehran, Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Ahmadi">Amir Ahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Ahmadi"> Hossein Ahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Ahmadi"> Alireza Ahmadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Emotional Intelligence (EI) has been defined as the ability to empathize, persevere, control impulses, communicate clearly, make thoughtful decisions, solve problems, and work with others in a way that earns friends and success. These abilities allow an individual to recognize and regulate emotion, develop self-control, set goals, develop empathy, resolve conflicts, and develop skills needed for leadership and effective group participation. Due to the increasing complexity of organizations and different ways of thinking, attitudes and beliefs of individuals, conflict as an important part of organizational life has been examined frequently. The main point is that the conflict is not necessarily in organization, unnecessary; but it can be more creative (increase creativity), to promote innovation. The purpose of this study was to investigate the relation between principals emotional intelligence as one of the factors affecting conflict management among teachers. This relation was analyzed through cluster sampling with a sample size consisting of 120 individuals. The results of the study showed that at the 95% level of confidence, the two secondary hypotheses (i.e. relation between emotional intelligence of principals and use of competition and cooperation strategies of conflict management among teachers) were confirmed, but the other three secondary hypotheses (i.e. the relation between emotional intelligence of managers and use of avoidance, adaptation and adaptability strategies of conflict management among teachers) were rejected. The primary hypothesis (i.e. relation between emotional intelligence of principals with conflict management among teachers) is supported. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emotional%20intelligence" title="emotional intelligence">emotional intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=conflict" title=" conflict"> conflict</a>, <a href="https://publications.waset.org/abstracts/search?q=conflict%20management" title=" conflict management"> conflict management</a>, <a href="https://publications.waset.org/abstracts/search?q=strategies%20of%20conflict%20management" title=" strategies of conflict management"> strategies of conflict management</a> </p> <a href="https://publications.waset.org/abstracts/40729/investigating-the-relationship-between-emotional-intelligence-of-principals-in-high-schoolssecondary-school-principals-and-teachers-conflict-management-a-case-study-on-secondary-schools-tehran-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40729.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">355</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">113</span> Mosque as a Sustainable Model in Iranian Traditional Urban Development: The Case Study of Vakil Mosque in Shiraz</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Hossein%20Ashari">Amir Hossein Ashari</a>, <a href="https://publications.waset.org/abstracts/search?q=Sedighe%20Erfan%20Manesh"> Sedighe Erfan Manesh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> When investigating Iranian traditional and historical urban development, such as that seen in Shiraz, our attention is drawn to mosques as a focal point. Vakil Mosque in Shiraz is completely consistent, coordinated and integrated with the Bazaar, square and school. This is a significant example of traditional urban development. The position of the mosque in the most important urban joint near bazaar in a way that it is considered part of the bazaar structure are factors that have given it social, political, and economic roles in addition to the original religious role. These are among characteristics of sustainable development. The mosque has had an important effect in formation of the city because it is connected to main gates. In terms of access, the mosque has different main and peripheral access paths from different parts of the city. The courtyard of the mosque was located next to the main elements of the city so that it was considered as an urban open space, which made it a more active and more dynamic place. This study is carried out via library and field research with the purpose of finding strategies for taking advantage of useful features of the mosque in traditional urban development. These features include its role as a gathering center for people and city in sustainable urban development. Mosque can be used as a center for enhancing social interactions and creating a sense of association that leads to sustainable social space. These can act as a model which leads us to sustainable cities in terms of social and economic factors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mosque" title="mosque">mosque</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20urban%20development" title=" traditional urban development"> traditional urban development</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20social%20space" title=" sustainable social space"> sustainable social space</a>, <a href="https://publications.waset.org/abstracts/search?q=Vakil%20Mosque" title=" Vakil Mosque"> Vakil Mosque</a>, <a href="https://publications.waset.org/abstracts/search?q=Shiraz" title=" Shiraz"> Shiraz</a> </p> <a href="https://publications.waset.org/abstracts/4977/mosque-as-a-sustainable-model-in-iranian-traditional-urban-development-the-case-study-of-vakil-mosque-in-shiraz" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4977.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">405</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">112</span> Gender Equality at Workplace in Iran - Strategies and Successes Against Systematic Bias</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leila%20Sadeghi">Leila Sadeghi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gender equality is a critical concern in the workplace, particularly in Iran, where legal and social barriers contribute to significant disparities. This abstract presents a case study of Dahi Bondad Co., a company based in Tehran, Iran that recognized the urgency of addressing the gender gap within its organization. Through a comprehensive investigation, the company identified issues related to biased recruitment, pay disparities, promotion biases, internal barriers, and everyday boundaries. This abstract highlights the strategies implemented by Dahi Bondad Co. to combat these challenges and foster gender equality. The company revised its recruitment policies, eliminated gender-specific language in job advertisements, and implemented blind resume screening to ensure equal opportunities for all applicants. Comprehensive pay equity analyses were conducted, leading to salary adjustments based on qualifications and experience to rectify pay disparities. Clear and transparent promotion criteria were established, and training programs were provided to decision-makers to raise awareness about unconscious biases. Additionally, mentorship and coaching programs were introduced to support female employees in overcoming self-limiting beliefs and imposter syndrome. At the same time, practical workshops and gamification techniques were employed to boost confidence and encourage women to step out of their comfort zones. The company also recognized the importance of dress codes and allowed optional hijab-wearing, respecting local traditions while promoting individual freedom. As a result of these strategies, Dahi Bondad Co. successfully fostered a more equitable and empowering work environment, leading to increased job satisfaction for both male and female employees within a short timeframe. This case study serves as an example of practical approaches that human resource managers can adopt to address gender inequality in the workplace, providing valuable insights for organizations seeking to promote gender equality in similar contexts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender%20equality" title="gender equality">gender equality</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20resource%20strategies" title=" human resource strategies"> human resource strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=legal%20barrier" title=" legal barrier"> legal barrier</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20barrier" title=" social barrier"> social barrier</a>, <a href="https://publications.waset.org/abstracts/search?q=successful%20result" title=" successful result"> successful result</a>, <a href="https://publications.waset.org/abstracts/search?q=successful%20strategies" title=" successful strategies"> successful strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=workplace%20in%20Iran" title=" workplace in Iran"> workplace in Iran</a> </p> <a href="https://publications.waset.org/abstracts/167705/gender-equality-at-workplace-in-iran-strategies-and-successes-against-systematic-bias" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167705.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">67</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">111</span> Fabrication of Carbon Nanoparticles and Graphene Using Pulsed Laser Ablation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Davoud%20Dorranian">Davoud Dorranian</a>, <a href="https://publications.waset.org/abstracts/search?q=Hajar%20Sadeghi"> Hajar Sadeghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Elmira%20Solati"> Elmira Solati </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carbon nanostructures in various forms were synthesized using pulsed laser ablation of a graphite target in different liquid environment. The beam of a Q-switched Nd:YAG laser of 1064-nm wavelength at 7-ns pulse width is employed to irradiate the solid target in water, acetone, alcohol, and cetyltrimethylammonium bromide (CTAB). Then the effect of the liquid environment on the characteristic of carbon nanostructures produced by laser ablation was investigated. The optical properties of the carbon nanostructures were examined at room temperature by UV–Vis-NIR spectrophotometer. The crystalline structure of the carbon nanostructures was analyzed by X-ray diffraction (XRD). The morphology of samples was investigated by field emission scanning electron microscope (FE-SEM). Transmission electron microscope (TEM) was employed to investigate the form of carbon nanostructures. Raman spectroscopy was used to determine the quality of carbon nanostructures. Results show that different carbon nanostructures such as nanoparticles and few-layer graphene were formed in various liquid environments. The UV-Vis-NIR absorption spectra of samples reveal that the intensity of absorption peak of nanoparticles in alcohol is higher than the other liquid environments due to the larger number of nanoparticles in this environment. The red shift of the absorption peak of the sample in acetone confirms that produced carbon nanoparticles in this liquid are averagely larger than the other medium. The difference in the intensity and shape of the absorption peak indicated the effect of the liquid environment in producing the nanoparticles. The XRD pattern of the sample in water indicates an amorphous structure due to existence the graphene sheets. X-ray diffraction pattern shows that the degree of crystallinity of sample produced in CTAB is higher than the other liquid environments. Transmission electron microscopy images reveal that the generated carbon materials in water are graphene sheet and in the other liquid environments are graphene sheet and spherical nanostructures. According to the TEM images, we have the larger amount of carbon nanoparticles in the alcohol environment. FE-SEM micrographs indicate that in this liquids sheet like structures are formed however in acetone, produced sheets are adhered and these layers overlap with each other. According to the FE-SEM micrographs, the surface morphology of the sample in CTAB was coarser than that without surfactant. From Raman spectra, it can be concluded the distinct shape, width, and position of the graphene peaks and corresponding graphite source. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanostructures" title="carbon nanostructures">carbon nanostructures</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene" title=" graphene"> graphene</a>, <a href="https://publications.waset.org/abstracts/search?q=pulsed%20laser%20ablation" title=" pulsed laser ablation"> pulsed laser ablation</a>, <a href="https://publications.waset.org/abstracts/search?q=graphite" title=" graphite"> graphite</a> </p> <a href="https://publications.waset.org/abstracts/36792/fabrication-of-carbon-nanoparticles-and-graphene-using-pulsed-laser-ablation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36792.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">314</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">110</span> Determinants of Non-Performing Loans: An Empirical Investigation of Bank-Specific Micro-Economic Factors </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Ikram">Amir Ikram</a>, <a href="https://publications.waset.org/abstracts/search?q=Faisal%20Ijaz"> Faisal Ijaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Qin%20Su"> Qin Su</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The empirical study was undertaken to explore the determinants of non-performing loans (NPLs) of small and medium enterprises (SMEs) sector held by the commercial banks. Primary data was collected through well-structured survey questionnaire from credit analysts/bankers of 42 branches of 9 commercial banks, operating in the district of Lahore (Pakistan), for 2014-2015. Selective descriptive analysis and Pearson chi-square technique were used to illustrate and evaluate the significance of different variables affecting NPLs. Branch age, duration of the loan, and credit policy were found to be significant determinants of NPLs. The study proposes that bank-specific and SME-specific microeconomic variables directly influence NPLs, while macroeconomic factors act as intermediary variables. Framework exhibiting causal nexus of NPLs was also drawn on the basis of empirical findings. The results elaborate various origins of NPLs and suggest that they are primarily instigated by the loan sanctioning procedure of the financial institution. The paper also underlines the risk management practices adopted by the bank at branch level to averse the risk of loan default. Empirical investigation of bank-specific microeconomic factors of NPLs with respect to Pakistan’s economy is the novelty of the study. Broader strategic policy implications are provided for credit analysts and entrepreneurs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=commercial%20banks" title="commercial banks">commercial banks</a>, <a href="https://publications.waset.org/abstracts/search?q=microeconomic%20factors" title=" microeconomic factors"> microeconomic factors</a>, <a href="https://publications.waset.org/abstracts/search?q=non-performing%20loans" title=" non-performing loans"> non-performing loans</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20and%20medium%20enterprises" title=" small and medium enterprises"> small and medium enterprises</a> </p> <a href="https://publications.waset.org/abstracts/53762/determinants-of-non-performing-loans-an-empirical-investigation-of-bank-specific-micro-economic-factors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53762.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">259</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">109</span> Simulation of a Three-Link, Six-Muscle Musculoskeletal Arm Activated by Hill Muscle Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nafiseh%20Ebrahimi">Nafiseh Ebrahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Jafari"> Amir Jafari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study of humanoid character is of great interest to researchers in the field of robotics and biomechanics. One might want to know the forces and torques required to move a limb from an initial position to the desired destination position. Inverse dynamics is a helpful method to compute the force and torques for an articulated body limb. It enables us to know the joint torques required to rotate a link between two positions. Our goal in this study was to control a human-like articulated manipulator for a specific task of path tracking. For this purpose, the human arm was modeled with a three-link planar manipulator activated by Hill muscle model. Applying a proportional controller, values of force and torques applied to the joints were calculated by inverse dynamics, and then joints and muscle forces trajectories were computed and presented. To be more accurate to say, the kinematics of the muscle-joint space was formulated by which we defined the relationship between the muscle lengths and the geometry of the links and joints. Secondary, the kinematic of the links was introduced to calculate the position of the end-effector in terms of geometry. Then, we considered the modeling of Hill muscle dynamics, and after calculation of joint torques, finally, we applied them to the dynamics of the three-link manipulator obtained from the inverse dynamics to calculate the joint states, find and control the location of manipulator’s end-effector. The results show that the human arm model was successfully controlled to take the designated path of an ellipse precisely. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arm%20manipulator" title="arm manipulator">arm manipulator</a>, <a href="https://publications.waset.org/abstracts/search?q=hill%20muscle%20model" title=" hill muscle model"> hill muscle model</a>, <a href="https://publications.waset.org/abstracts/search?q=six-muscle%20model" title=" six-muscle model"> six-muscle model</a>, <a href="https://publications.waset.org/abstracts/search?q=three-link%20lodel" title=" three-link lodel"> three-link lodel</a> </p> <a href="https://publications.waset.org/abstracts/113960/simulation-of-a-three-link-six-muscle-musculoskeletal-arm-activated-by-hill-muscle-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113960.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">108</span> Examination of State of Repair of Buildings in Private Housing Estates in Enugu Metropolis, Enugu State Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Umeora%20Chukwunonso%20Obiefuna">Umeora Chukwunonso Obiefuna </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The private sector in housing provision continually take steps towards addressing part of the problem of cushioning the effect of the housing shortage in Nigeria by establishing housing estates since the government alone cannot provide housing for everyone. This research examined and reported findings from research conducted on the state of repair of buildings in private housing estates in Enugu metropolis, Enugu state Nigeria. The objectives of the study were to examine the physical conditions of the building fabrics and appraise the performance of infrastructural services provided in the buildings. The questionnaire was used as a research instrument to elicit data from respondents. Stratified sampling of the estates based on building type was adopted as a sampling method for this study. Findings from the research show that the state of repair of most buildings require minor repairs to make them fit for habitation and sound to ensure the well-being of the residents. In addition, four independent variables from the nine independent variables investigated significantly explained residual variation in the dependent variable - state of repair of the buildings in the study area. These variables are: Average Monthly Income of Residents (AMIR), Length of Stay of the Residents in the estates (LSY), Type of Wall Finishes on the buildings (TWF), and Time Taken to Respond to Resident’s complaints by the estate managers (TTRC). With this, the linear model was established for predicting the state of repair of buildings in private housing estates in the study area. This would assist in identifying variables that are lucid in predicting the state of repair of the buildings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building" title="building">building</a>, <a href="https://publications.waset.org/abstracts/search?q=housing%20estate" title=" housing estate"> housing estate</a>, <a href="https://publications.waset.org/abstracts/search?q=private" title=" private"> private</a>, <a href="https://publications.waset.org/abstracts/search?q=repair" title=" repair"> repair</a> </p> <a href="https://publications.waset.org/abstracts/122084/examination-of-state-of-repair-of-buildings-in-private-housing-estates-in-enugu-metropolis-enugu-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122084.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">141</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">107</span> Impact of Emotional Intelligence of Principals in High Schools on Teachers Conflict Management: A Case Study on Secondary Schools, Tehran, Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Ahmadi">Amir Ahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Ahmadi"> Hossein Ahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Ahmadi"> Alireza Ahmadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Emotional Intelligence (EI) has been defined as the ability to empathize, persevere, control impulses, communicate clearly, make thoughtful decisions, solve problems, and work with others in a way that earns friends and success. These abilities allow an individual to recognize and regulate emotion, develop self-control, set goals, develop empathy, resolve conflicts, and develop skills needed for leadership and effective group participation. Due to the increasing complexity of organizations and different ways of thinking, attitudes and beliefs of individuals, Conflict as an important part of organizational life has been examined frequently. The main point is that the conflict is not necessarily in organization, unnecessary; But it can be more creative (increase creativity), to promote innovation, or may avoid wasting energy and resources of the organization. The purpose of this study was to investigate the relation between principals emotional intelligence as one of the factors affecting conflict management among teachers. This relation was analyzed through cluster sampling with a sample size consisting of 120 individuals. The results of the study showed that, at the 95% level of confidence, the two secondary hypotheses (i.e. relation between emotional intelligence of principals and use of competition and cooperation strategies of conflict management among teachers)were confirmed, but the other three secondary hypotheses (i.e. the relation between emotional intelligence of managers and use of avoidance, adaptation and adaptability strategies of conflict management among teachers) were rejected. The primary hypothesis (i.e. relation between emotional intelligence of principals with conflict management among teachers) is supported. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emotional%20intelligence" title="emotional intelligence">emotional intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=conflict" title=" conflict"> conflict</a>, <a href="https://publications.waset.org/abstracts/search?q=conflict%20management" title=" conflict management"> conflict management</a>, <a href="https://publications.waset.org/abstracts/search?q=strategies%20of%20conflict%20management" title=" strategies of conflict management"> strategies of conflict management</a> </p> <a href="https://publications.waset.org/abstracts/44190/impact-of-emotional-intelligence-of-principals-in-high-schools-on-teachers-conflict-management-a-case-study-on-secondary-schools-tehran-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44190.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">356</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">106</span> Systems Engineering Management Using Transdisciplinary Quality System Development Lifecycle Model </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Asaad%20Abdelrazek">Mohamed Asaad Abdelrazek</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Taher%20El-Sheikh"> Amir Taher El-Sheikh</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Zayan"> M.

Managing the systems development lifecycle requires technical management. Systems engineering management is the technical management. Systems engineering management is accomplished by incorporating many activities. The three major activities are development phasing, systems engineering process and lifecycle integration. Systems engineering management activities are performed across the system development lifecycle. Due to the ever-increasing complexity of systems as well the difficulty of managing and tracking the development activities, new ways to achieve systems engineering management activities are required. This paper presents a systematic approach used as a design management tool applied across systems engineering management roles. In this approach, Transdisciplinary System Development Lifecycle (TSDL) Model has been modified and integrated with Quality Function Deployment. Hereinafter, the name of the systematic approach is the Transdisciplinary Quality System Development Lifecycle (TQSDL) Model. The QFD translates the voice of customers (VOC) into measurable technical characteristics. The modified TSDL model is based on Axiomatic Design developed by Suh which is applicable to all designs: products, processes, systems and organizations. The TQSDL model aims to provide a robust structure and systematic thinking to support the implementation of systems engineering management roles. This approach ensures that the customer requirements are fulfilled as well as satisfies all the systems engineering manager roles and activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axiomatic%20design" title="axiomatic design">axiomatic design</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20function%20deployment" title=" quality function deployment"> quality function deployment</a>, <a href="https://publications.waset.org/abstracts/search?q=systems%20engineering%20management" title=" systems engineering management"> systems engineering management</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20development%20lifecycle" title=" system development lifecycle"> system development lifecycle</a> </p> <a href="https://publications.waset.org/abstracts/63058/systems-engineering-management-using-transdisciplinary-quality-system-development-lifecycle-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63058.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">362</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">105</span> The Frequency of Q Fever Among Hospitalized Patients with Pyrexia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Ali%20Abood%20Nassrullah">Hassan Ali Abood Nassrullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Jabbar%20Fadeel%20Mahdi"> Jabbar Fadeel Mahdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Salih%20Mahdi%20Alkurdi"> Mohammed Salih Mahdi Alkurdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Al%20Mousawi"> Ali Al Mousawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Saad%20Ibrahim%20Al-Ghabban"> Saad Ibrahim Al-Ghabban</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Amir%20H.%20Kadhum"> Abdul Amir H.

Objective: The aim of this study is To estimate the prevalence of cases of Q fever in hospitalized febrile patients in Imam Al Hussain Teaching Medical City in Karbala. Methods: One hundred patients with pyrexia were admitted to the medical ward from 1st August to 31st December 2019. Serological procedures fortified by Enzyme-linked Immunosorbent Assay test. Patients were considered to have acute Q fever when the specific antibodies (IgM and IgG) of phase II of Coxiella burnetii were positive. Results: The mean age of the patients was 35.05±12.93 years; females constituted 60% of them. Eighteen patients (18%) showed positive results for IgM, a lower proportion (13% n=13) had positive IgG levels, and 9% showed equivocal results. Statistical analysis revealed a significant association between positive IgM levels of the female gender and in patients consuming unpasteurized milk. One patient (female aged 60 years) died in the hospital, while all other patients were discharged well. Two female patients were pregnant, and one of them had an abortion. Conclusions: Q fever is more common in febrile patients. The study indicates that this disease should not be overlooked in the differential diagnosis of acute fever. Serological testing should be performed in all patients with acute febrile illness with an unsettling diagnosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibodies" title="antibodies">antibodies</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency" title=" frequency"> frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=immunoglobulin%20IgM" title=" immunoglobulin IgM"> immunoglobulin IgM</a>, <a href="https://publications.waset.org/abstracts/search?q=Q%20fever" title=" Q fever"> Q fever</a> </p> <a href="https://publications.waset.org/abstracts/154564/the-frequency-of-q-fever-among-hospitalized-patients-with-pyrexia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154564.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">123</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">104</span> Predicting Costs in Construction Projects with Machine Learning: A Detailed Study Based on Activity-Level Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soheila%20Sadeghi">Soheila Sadeghi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Construction projects are complex and often subject to significant cost overruns due to the multifaceted nature of the activities involved. Accurate cost estimation is crucial for effective budget planning and resource allocation. Traditional methods for predicting overruns often rely on expert judgment or analysis of historical data, which can be time-consuming, subjective, and may fail to consider important factors. However, with the increasing availability of data from construction projects, machine learning techniques can be leveraged to improve the accuracy of overrun predictions. This study applied machine learning algorithms to enhance the prediction of cost overruns in a case study of a construction project. The methodology involved the development and evaluation of two machine learning models: Random Forest and Neural Networks. Random Forest can handle high-dimensional data, capture complex relationships, and provide feature importance estimates. Neural Networks, particularly Deep Neural Networks (DNNs), are capable of automatically learning and modeling complex, non-linear relationships between input features and the target variable. These models can adapt to new data, reduce human bias, and uncover hidden patterns in the dataset. The findings of this study demonstrate that both Random Forest and Neural Networks can significantly improve the accuracy of cost overrun predictions compared to traditional methods. The Random Forest model also identified key cost drivers and risk factors, such as changes in the scope of work and delays in material delivery, which can inform better project risk management. However, the study acknowledges several limitations. First, the findings are based on a single construction project, which may limit the generalizability of the results to other projects or contexts. Second, the dataset, although comprehensive, may not capture all relevant factors influencing cost overruns, such as external economic conditions or political factors. Third, the study focuses primarily on cost overruns, while schedule overruns are not explicitly addressed. Future research should explore the application of machine learning techniques to a broader range of projects, incorporate additional data sources, and investigate the prediction of both cost and schedule overruns simultaneously. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cost%20prediction" title="cost prediction">cost prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=project%20management" title=" project management"> project management</a>, <a href="https://publications.waset.org/abstracts/search?q=random%20forest" title=" random forest"> random forest</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20networks" title=" neural networks"> neural networks</a> </p> <a href="https://publications.waset.org/abstracts/187028/predicting-costs-in-construction-projects-with-machine-learning-a-detailed-study-based-on-activity-level-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187028.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">54</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">103</span> A Machine Learning Approach for Efficient Resource Management in Construction Projects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soheila%20Sadeghi">Soheila Sadeghi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Construction projects are complex and often subject to significant cost overruns due to the multifaceted nature of the activities involved.

These models can adapt to new data, reduce human bias, and uncover hidden patterns in the dataset. The findings of this study demonstrate that both Random Forest and Neural Networks can significantly improve the accuracy of cost overrun predictions compared to traditional methods. The Random Forest model also identified key cost drivers and risk factors, such as changes in the scope of work and delays in material delivery, which can inform better project risk management. However, the study acknowledges several limitations. First, the findings are based on a single construction project, which may limit the generalizability of the results to other projects or contexts. Second, the dataset, although comprehensive, may not capture all relevant factors influencing cost overruns, such as external economic conditions or political factors. Third, the study focuses primarily on cost overruns, while schedule overruns are not explicitly addressed. Future research should explore the application of machine learning techniques to a broader range of projects, incorporate additional data sources, and investigate the prediction of both cost and schedule overruns simultaneously. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=resource%20allocation" title="resource allocation">resource allocation</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=data-driven%20decision-making" title=" data-driven decision-making"> data-driven decision-making</a>, <a href="https://publications.waset.org/abstracts/search?q=project%20management" title=" project management"> project management</a> </p> <a href="https://publications.waset.org/abstracts/187029/a-machine-learning-approach-for-efficient-resource-management-in-construction-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187029.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">38</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">102</span> Investigating the Formation of Nano-Hydroxyapatite on a Biocompatible and Antibacterial Cu/Mg-Substituted Bioglass</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elhamalsadat%20Ghaffari">Elhamalsadat Ghaffari</a>, <a href="https://publications.waset.org/abstracts/search?q=Moghan%20Amirhosseinian"> Moghan Amirhosseinian</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Khaleghipour"> Amir Khaleghipour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Multifunctional bioactive glasses (BGs) are designed with a focus on the provision of bactericidal and biological properties desired for angiogenesis, osteogenesis, and ultimately potential applications in bone tissue engineering. To achieve these, six sol-gel copper/magnesium substituted derivatives of 58S-BG, i.e. a mol% series of 60SiO<sub>2</sub>-4P<sub>2</sub>O<sub>5</sub>-5CuO-(31-x) CaO/xMgO (where x=0, 1, 3, 5, 8, and 10), were synthesized. Afterwards, the effect of MgO/CaO substitution on the <em>in vitro</em> formation of nano-hydroxyapatite (HA), osteoblast-like cell responses and BGs antibacterial performance were studied. During the BGs synthesis, the elimination of nitrates was achieved at 700 °C that prevented the BGs crystallization and stabilized the obtained dried gels. The structural and morphological evaluations were performed with X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). These characterizations revealed that Cu-substituted 58S-BG consisting of 5 mol% MgO (BG-5/5) slightly had retarded the formation of HA. In addition, Cu-substituted 58S-BGs consisting 8 mol% and 10 mol% MgO (BG-5/8 and BG-5/10) displayed lower bioactivity probably due to the lower ion release rate of Ca–Si into the simulated body fluid (SBF). The determination of 3-(4, 5 dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) and alkaline phosphate (ALP) activities proved that the highest values of both differentiation and proliferation of MC3T3-E1 cells can be obtained from a 5 mol% MgO substituted BG, while the over addition of MgO (8 mol% and 10 mol%) decreased the bioactivity. Furthermore, these novel Cu/Mg-substituted 58S-BGs displayed antibacterial effect against methicillin-resistant <em>Staphylococcus aureus</em> bacteria. Taken together, the results suggest the equally-substituted BG-5/5 (i.e. the one consists of 5 mol% of both CuO and MgO) as a promising candidate for bone tissue engineering, among all newly designed BGs in this work, owing to its desirable cell proliferation, ALP activity and antibacterial properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apatite" title="apatite">apatite</a>, <a href="https://publications.waset.org/abstracts/search?q=bioactivity" title=" bioactivity"> bioactivity</a>, <a href="https://publications.waset.org/abstracts/search?q=biomedical%20applications" title=" biomedical applications"> biomedical applications</a>, <a href="https://publications.waset.org/abstracts/search?q=sol-gel%20processes" title=" sol-gel processes"> sol-gel processes</a> </p> <a href="https://publications.waset.org/abstracts/107301/investigating-the-formation-of-nano-hydroxyapatite-on-a-biocompatible-and-antibacterial-cumg-substituted-bioglass" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107301.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">128</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">101</span> Examining Resilience, Social Supports, and Self-Esteem as Predictors of the Quality of Life of ODAPUS (Orang Dengan Lupus)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yulmaida%20Amir">Yulmaida Amir</a>, <a href="https://publications.waset.org/abstracts/search?q=Fahrul%20Rozi"> Fahrul Rozi</a>, <a href="https://publications.waset.org/abstracts/search?q=Insany%20C.%20Kamil"> Insany C.

The number of ODAPUS indicate an increase in Indonesia, thereby helping to improve their quality of life to be important to help their recovery. This study aims to examine the effect of resilience, self-esteem, and social support on the quality of life of women who had been diagnosed as having Lupus. Data were collected from 64 ODAPUS in Indonesia, using the World Health Organization Quality of Life (WHOQOL), Resilience Scale from Wagnil and Young (1993), self-esteem scale (developed from Coopersmith’s theory), and Social Support Questioner from Northouse (1988). Regression data analysis showed that resilience, social support, and self-esteem predict the quality of life of the ODAPUS simultaneously. If the variable was analysed individually, self-esteem did not significantly contribute to the quality of life. Resilience contributed most significantly to the quality of life, followed by social support. Of five sources of social supports included in the research, support from family members (parents and brother/sisters) has the most significant contribution to the quality of life, followed by support from spouse, and from friends. Interestingly, social support from medical personnel (medical doctors and nurses) had not a significant contribution to the quality of life of ODAPUS. As a conclusion, this research showed that the ability of ODAPUS to cope with difficulty in life, and support from family members, spouse, and friends were the significant predictors for their quality of life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title="quality of life">quality of life</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience" title=" resilience"> resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=self-esteem" title=" self-esteem"> self-esteem</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20supports" title=" social supports"> social supports</a> </p> <a href="https://publications.waset.org/abstracts/97461/examining-resilience-social-supports-and-self-esteem-as-predictors-of-the-quality-of-life-of-odapus-orang-dengan-lupus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97461.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">168</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">100</span> Role of Vocational Education and Training in Economic Excellence and Social Inclusion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ali%20Asadullah">Muhammad Ali Asadullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Zafarullah%20Amir"> Zafarullah Amir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, Vocational Education and Training (VET) has been under discussion by the academic researchers and remained in focus in the political grounds. Due to potential contribution of VET, the World Bank and United Nations Educational, Scientific and Cultural Organization (UNESCO) support vocational education to reduce poverty, enhance economic growth and increase competitiveness. This paper examines the impact of Vocational Education and Training on the Economic Growth and Social Inclusion with direct and mediation effect of Social Inclusion. The basic purpose of this study is to assess economic pay-offs as a result of long term investments in VET. Based on the review of Anderson Nilsson, initially we explored the increasing or decreasing trend in investment on VET. Further, the study explores that the countries which invest more on VET, tend to get more economic growth and are socially more ‘inclusive’. It is a longitudinal / panel data study with 12 years of registered data which involves 24 OECD countries. The results of the study indicate the VET has positive association with Social Inclusion and Economic Growth. Further, there is also a positive association of VET and Economic Growth through mediation of Social Inclusion. The current study considers not only issue and challenges in developing VET systems but also contributes to develop the theoretical framework for considering how VET can directly and indirectly improve economic growth and social inclusion. A wider appreciation of how VET’s benefits operate may influence a country’s decisions to invest in it. If policy makers increase investment on VET, the result would be positive in Economic Growth and Social Inclusion. It is also recommended that the same OECD model may be implemented in developing countries like Pakistan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vocational%20Education%20and%20Training%20%28VET%29" title="Vocational Education and Training (VET)">Vocational Education and Training (VET)</a>, <a href="https://publications.waset.org/abstracts/search?q=Social%20Inclusion" title=" Social Inclusion"> Social Inclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=Economic%20Growth" title=" Economic Growth"> Economic Growth</a>, <a href="https://publications.waset.org/abstracts/search?q=OECD%20countries" title=" OECD countries"> OECD countries</a> </p> <a href="https://publications.waset.org/abstracts/45479/role-of-vocational-education-and-training-in-economic-excellence-and-social-inclusion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45479.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">310</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">99</span> The Generation of Insulin Producing Cells from Human Mesenchymal Stem Cells by miR-375 and Anti-miR-9</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arefeh%20Jafarian">Arefeh Jafarian</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Taghikani"> Mohammad Taghikani</a>, <a href="https://publications.waset.org/abstracts/search?q=Saied%20Abroun"> Saied Abroun</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Allahverdi"> Amir Allahverdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Soleimani"> Masoud Soleimani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The miRNAs have key roles in control of pancreatic islet development and insulin secretion. In this regards, current study investigated the pancreatic differentiation of human bone marrow mesenchymal stem cells (hBM-MSCs) by up-regulation of miR-375 and down-regulation of miR-9 by lentiviruses containing miR-375 and anti-miR-9. Findings: After 21 days of induction, islet-like clusters containing insulin producing cells (IPCs) were confirmed by dithizone (DTZ) staining. The IPCs and β cell specific related genes and proteins were detected using qRT-PCR and immunofluorescence on days 7, 14 and 21 of differentiation. Glucose challenge test was performed at different concentrations of glucose as well as extracellular and intracellular insulin and C-peptide were assayed using ELISA kit. In derived IPCs by miR-375 alone are capable to express insulin and other endocrine specific transcription factors, the cells lack the machinery to respond to glucose. The differentiated hMSCs by miR-375 and anti-miR-9 lentiviruses could secrete insulin and c-peptide in a glucose-regulated manner. Conclusion: It was found that over-expression of miR-375 led to a reduction in levels of Mtpn protein in derived IPCs, while treatment with anti-miR-9 following miR-375 over-expression had synergistic effects on MSCs differentiation and insulin secretion in a glucose-regulated manner. The researchers reported that silencing of miR-9 increased OC-2 protein in IPCs that may contribute to the observed glucose-regulated insulin secretion. These findings highlight miRNAs functions in stem cells differentiation and suggest that they could be used as therapeutic tools for gene-based therapy in diabetes mellitus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabetes" title="diabetes">diabetes</a>, <a href="https://publications.waset.org/abstracts/search?q=differentiation" title=" differentiation"> differentiation</a>, <a href="https://publications.waset.org/abstracts/search?q=MSCs" title=" MSCs"> MSCs</a>, <a href="https://publications.waset.org/abstracts/search?q=insulin%20producing%20cells" title=" insulin producing cells"> insulin producing cells</a>, <a href="https://publications.waset.org/abstracts/search?q=miR-375" title=" miR-375"> miR-375</a>, <a href="https://publications.waset.org/abstracts/search?q=miR-9" title=" miR-9 "> miR-9 </a> </p> <a href="https://publications.waset.org/abstracts/31158/the-generation-of-insulin-producing-cells-from-human-mesenchymal-stem-cells-by-mir-375-and-anti-mir-9" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31158.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">317</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">98</span> Development of Electrospun Porous Carbon Fibers from Cellulose/Polyacrylonitrile Blend </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zubair%20Khaliq">Zubair Khaliq</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Bilal%20Qadir"> M.

The nanostructure of carbon fibers offers enhanced properties of conductivity due to the larger surface area. The next generation carbon nanofibers demand the porous structure as it offers more surface area. Multiple techniques are used to produce carbon fibers. However, electrospinning followed by carbonization of the polymeric materials is easy to carry process on a laboratory scale. Also, it offers multiple diversity of changing parameters to acquire the desired properties of carbon fibers. Polyacrylonitrile (PAN) is the most used material for the production of carbon fibers due to its promising processing parameters. Also, cellulose is one of the highest yield producers of carbon fibers. However, the electrospinning of cellulosic materials is difficult due to its rigid chain structure. The combination of PAN and cellulose can offer a suitable solution for the production of carbon fibers. Both materials are miscible in the mixed solvent of N, N, Dimethylacetamide and lithium chloride. This study focuses on the production of porous carbon fibers as a function of PAN/Cellulose blend ratio, solution properties, and electrospinning parameters. These single polymer and blend with different ratios were electrospun to give fine fibers. The higher amount of cellulose offered more difficulty in electrospinning of nanofibers. After carbonization, the carbon fibers were studied in terms of their blend ratio, surface area, and texture. Cellulose contents offered the porous structure of carbon fibers. Also, the presence of LiCl contributed to the porous structure of carbon fibers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cellulose"
