The FL is condensed onto cellulose aldehyde using three diamine spacers (H₂N-NH₂, H₂N(CH₂)₂NH₂ and H₂N(CH₂)₃NH₂) to afford Cell=Spacer=FL. The obtained products were characterized by spectroscopic (FT-IR, UV–Vis), thermal gravimetric analysis (TGA), and microscopic (Optical, SEM) techniques. The UV-Vis spectra of the FL=N(CH₂)ₓNH₂ (x = 0, 2, 3) moieties show that they are transparent in the 375- 800 nm region while they exhibit intense absorption band below 350 nm attributed to n-π* and π-π* transitions. The solid-state photoluminescence (PLs-s) of the cold-pressed pellets of the FL=N(CH₂)ₓNH₂ and Cell=Spacer=FL placed in a quartz cuvette show strong emission in the 500-550 nm region upon irradiation with Xe lamp light (λex = 320 nm). The PLs-s green emission of the grafted Cell=Spacer=FL was evaluated relative to that of the FL-based precursor. These grafted conjugated products have the potential to be used as analyte sensors for typical nitroaromatics/aromatic amines and be further extended to immunoassay studies for aromatic amino acids such as phenylalanine and histidine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=luminescence" title="luminescence">luminescence</a>, <a href="https://publications.waset.org/abstracts/search?q=cellulose" title=" cellulose"> cellulose</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorenone" title=" fluorenone"> fluorenone</a>, <a href="https://publications.waset.org/abstracts/search?q=grafting" title=" grafting"> grafting</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20state" title=" solid state"> solid state</a> </p> <a href="https://publications.waset.org/abstracts/176946/solid-state-luminescence-of-fluorenone-grafted-onto-cellulose-aldehyde-backbone-using-different-organic-amine-spacers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176946.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">72</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">221</span> Towards a Rigorous Analysis for a Supercritical Particulate Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yousef%20Bakhbakhi">Yousef Bakhbakhi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Crystallization with supercritical fluids (SCFs), as a developed technology to produce particles of micron and sub-micron size with narrow size distribution, has found appreciable importance as an environmentally friendly technology. Particle synthesis using SCFs can be achieved employing a number of special processes involving solvent and antisolvent mechanisms. In this study, the compressed antisolvent (PCA) process is utilized as a model to analyze the theoretical complexity of crystallization with supercritical fluids. The population balance approach has proven to be an effectual technique to simulate and predict the particle size and size distribution. The nucleation and growth mechanisms of the particles formation in the PCA process is investigated using the population balance equation, which describes the evolution of the particle through coalescence and breakup levels with time. The employed mathematical population balance model contains a set of the partial differential equation with algebraic constraints, which demands a rigorous numerical approach. The combined Collocation and Galerkin finite element method are proposed as a high-resolution technique to solve the dynamics of the PCA process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=particle%20formation" title="particle formation">particle formation</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20size%20and%20size%20distribution" title=" particle size and size distribution"> particle size and size distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=PCA" title=" PCA"> PCA</a>, <a href="https://publications.waset.org/abstracts/search?q=supercritical%20carbon%20dioxide" title=" supercritical carbon dioxide"> supercritical carbon dioxide</a> </p> <a href="https://publications.waset.org/abstracts/89209/towards-a-rigorous-analysis-for-a-supercritical-particulate-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89209.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">197</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">220</span> Developing New Media Credibility Scale: A Multidimensional Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanaa%20Farouk%20Saleh">Hanaa Farouk Saleh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main purposes of this study are to develop a scale that reflects emerging theoretical understandings of new media credibility, based on the evolution of credibility studies in western researches, identification of the determinants of credibility in the media and its components by comparing traditional and new media credibility scales and building accumulative scale to test new media credibility. This approach was built on western researches using conceptualizations of media credibility, which focuses on four principal components: Source (journalist), message (article), medium (newspaper, radio, TV, web, etc.), and organization (owner of the medium), and adding user and cultural context as key components to assess new media credibility in particular. This study&rsquo;s value lies in its contribution to the conceptualization and development of new media credibility through the creation of a theoretical measurement tool.

This paper reviews bridge inspection and condition rating practices and introduces a defect-based urgency index. The index is estimated at the element-level based on the extent and severity of the different defects typical to the bridge element. The urgency index approach has the following advantages: (1) It facilitates judgment submission, i.e. instead of rating the bridge element with a specific linguistic overall expression (which can be subjective and used differently by different people), the approach is based on assessing the defects; (2) It captures multiple defects that can be present within a deteriorated element; and (3) It reflects how critical the element is through quantifying critical defects and their severity. The approach can be further developed and validated. It is expected to be useful for practical purposes as an early-warning system for critical bridge elements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=condition%20rating" title="condition rating">condition rating</a>, <a href="https://publications.waset.org/abstracts/search?q=deterioration" title=" deterioration"> deterioration</a>, <a href="https://publications.waset.org/abstracts/search?q=inspection" title=" inspection"> inspection</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance" title=" maintenance"> maintenance</a> </p> <a href="https://publications.waset.org/abstracts/51093/defect-based-urgency-index-for-bridge-maintenance-ranking-and-prioritization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51093.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">452</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">217</span> Transient Stability Improvement in Multi-Machine System Using Power System Stabilizer (PSS) and Static Var Compensator (SVC)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khoshnaw%20Khalid%20Hama%20Saleh">Khoshnaw Khalid Hama Saleh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ergun%20Ercelebi"> Ergun Ercelebi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Increasingly complex modern power systems require stability, especially for transient and small disturbances. Transient stability plays a major role in stability during fault and large disturbance. This paper compares a power system stabilizer (PSS) and static Var compensator (SVC) to improve damping oscillation and enhance transient stability. The effectiveness of a PSS connected to the exciter and/or governor in damping electromechanical oscillations of isolated synchronous generator was tested. The SVC device is a member of the shunt FACTS (flexible alternating current transmission system) family, utilized in power transmission systems. The designed model was tested with a multi-machine system consisting of four machines six bus, using MATLAB/SIMULINK software.

In the present study, the molecular hybridization tool was adopted to obtain six Schiff bases of isatin and adamantane-1-carbohydrazide (18–23). Then, their anticonvulsant activity was evaluated using a pentylenetetrazole- (PTZ-) induced seizure model using phenobarbitone as a positive control. Our findings showed that compounds 18–23 provided significant protection against PTZ-induced seizure, and maximum activities were associated with compound 23. Moreover, all investigated compounds increased the latency of induced convulsion and reduced the duration of epilepsy, with compound 23 being the best. Interestingly, most of the synthesized molecules showed a reduction in neurological symptoms and severity of the seizure. Molecular docking studies suggest GABA-A receptor as a potential target, and in silico ADME screening revealed that the pharmaceutical properties of compound 23 are within the specified limit. Thus, compound 23 was identified as a promising candidate that warrants further drug discovery processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=isatin%20and%20adamantane" title="isatin and adamantane">isatin and adamantane</a>, <a href="https://publications.waset.org/abstracts/search?q=anticonvulsant%20activity" title=" anticonvulsant activity"> anticonvulsant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=PTZ-induced%20seizure" title=" PTZ-induced seizure"> PTZ-induced seizure</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20docking" title=" molecular docking"> molecular docking</a> </p> <a href="https://publications.waset.org/abstracts/145055/schiff-bases-of-isatin-and-admantane-1-carbohydrazide-synthesis-characterization-and-anticonvulsant-activity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145055.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">207</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">215</span> Contestation of Local and Non-Local Knowledge in Developing Bali Cattle at Barru Regency, Province of South Sulawesi, Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Amidah%20Amrawaty">A.

Reviewing and updating competencies’ curriculum matrix is one of the critical and complicated processes that consume time and effort, and this has triggered searching for a scientific and sustainable approach to manage the such review. This paper presents a novel approach of implementing Lean (5S) methodology in reviewing technical competencies required for the graduates of the Military Technological College (MTC) in the Sultanate of Oman. The 5S framework has been imbedded into an action plan using the PDCA cycle. As a result, the method applied has helped in sorting out the actual required competencies, the team has identified the required (new, amended, and deleted) competencies in all of the targeted Engineering Departments, in addition, the major wastes within the overall process were identified, and the future review process was standardized and documented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PDCA" title="PDCA">PDCA</a>, <a href="https://publications.waset.org/abstracts/search?q=5S" title=" 5S"> 5S</a>, <a href="https://publications.waset.org/abstracts/search?q=lean" title=" lean"> lean</a>, <a href="https://publications.waset.org/abstracts/search?q=MTC" title=" MTC"> MTC</a>, <a href="https://publications.waset.org/abstracts/search?q=competencies" title=" competencies"> competencies</a>, <a href="https://publications.waset.org/abstracts/search?q=curriculum%20matrix" title=" curriculum matrix"> curriculum matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title=" higher education"> higher education</a> </p> <a href="https://publications.waset.org/abstracts/166092/implementation-of-5s-lean-methodology-in-reviewing-competencies-in-a-higher-education-institution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166092.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">94</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">213</span> Chelating Effect of Black Tea Extract Compared to Citric Acid in the Process of the Oxidation of Sunflower, Canola, Olive, and Tallow Oils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yousef%20Naserzadeh">Yousef Naserzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Niloufar%20Mahmoudi"> Niloufar Mahmoudi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Oxidation resistance is one of the important parameters in maintaining the quality of olive oil during its storage. Ensuring the stability of the quality of olive oil is one of the important concerns of the producers and consumers. Prooxidants such as iron and copper accelerate the oxidation reaction, and also anti-oxidants and chelating compounds delay it. In this study, chelating effect of tea extract which contains significant amounts of tannic acid is investigated in comparison with citric acid. To do it, 0.1 ppm copper was added to these four kinds of oil, sunflower, olive, canola, and tallow, and then chelating effect of citric acid (0.01%), tannic acid (0.01%) and tea extract (0.1%) were measured by adding to this composition. To this end, the resistance time of the oils against oxidation was measured at 120 °C and an air flow of 20 liters per hour. And the value of peroxide was measured by oven test in six periods of 24 hours at 105 °C. The results showed that citric acid, tannic acid and tea extract had chelating property and increased the resistance time of the studied oils. As a result, considering chelating property and increasing resistance of oil, tannic acid showed better effect than tea extract and tea extract had better effect than citric acid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tannic%20acid" title="tannic acid">tannic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=chelate" title=" chelate"> chelate</a>, <a href="https://publications.waset.org/abstracts/search?q=edible%20oils" title=" edible oils"> edible oils</a>, <a href="https://publications.waset.org/abstracts/search?q=black%20tea%20extract" title=" black tea extract"> black tea extract</a>, <a href="https://publications.waset.org/abstracts/search?q=TBHQ" title=" TBHQ"> TBHQ</a> </p> <a href="https://publications.waset.org/abstracts/90906/chelating-effect-of-black-tea-extract-compared-to-citric-acid-in-the-process-of-the-oxidation-of-sunflower-canola-olive-and-tallow-oils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90906.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">203</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">212</span> The Effects of Microsilis, Super Plasticizer and Air Entrain in Lightweight Expanded Perlite Concrete </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yousef%20Zandi">Yousef Zandi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoseyn%20Leka"> Hoseyn Leka</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahin%20Ganadi"> Mahin Ganadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the results of a laboratory study carried out on effect of using the simultaneous of microsilis, super plasticizer and air entrain additives on compressive strength of light weight perlite concrete. In this study, 63 test specimens with different percentage and mixtures including microsilis, super plasticizer and air entrain were used. 63 test specimens with different mixtures including microsilis and air entrain were also prepared for comparison purposes. In the mixtures, lightweight perlite aggregate, microsilis, super plasticizer, air entrain, cement type I, sand and water were used. Laboratory test results showed that workability of lightweight perlite concrete was increased and compressive strength was released by the use of super plasticizer, without any change in water/cement ratio. We know that compressive strength of concrete is depends on water/cement ratio. Since, it was expected that the use of air entrain and super plasticizer lower water/cement ratio and raised strengths, considerably. It was concluded that use of simultaneous of air entrains and super plasticizer additive were not economical and use of air entrain and microsilis is better than use of air entrain, super plasticizer and microsilis. It was concluded that the best results were obtained by using 10% microsilis and 0.5% air entrain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=perlite" title="perlite">perlite</a>, <a href="https://publications.waset.org/abstracts/search?q=microsilis" title=" microsilis"> microsilis</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20entrain" title=" air entrain"> air entrain</a>, <a href="https://publications.waset.org/abstracts/search?q=super%20plasticizer" title=" super plasticizer "> super plasticizer </a> </p> <a href="https://publications.waset.org/abstracts/19134/the-effects-of-microsilis-super-plasticizer-and-air-entrain-in-lightweight-expanded-perlite-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19134.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">384</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">211</span> Predictors of Non-Alcoholic Fatty Liver Disease in Egyptian Obese Adolescents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moushira%20Zaki">Moushira Zaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Wafaa%20Ezzat"> Wafaa Ezzat</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasser%20Elhosary"> Yasser Elhosary</a>, <a href="https://publications.waset.org/abstracts/search?q=Omnia%20Saleh"> Omnia Saleh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nonalcoholic fatty liver disease (NAFLD) has increased in conjunction with obesity.

All were subjected to anthropometry, biochemical analysis and abdominal ultrasongraphic assessment. Metabolic syndrome (MS) was diagnosed according to the IDF criteria. Significant association between presence of MS and NAFLD was observed. Obese adolescents with NAFLD had significantly higher levels of ALT, triglycerides, fasting glucose, insulin, blood pressure and HOMA-IR, whereas decreased HDL-C levels as compared with obese cases without NAFLD.

WMNs provide network access to the clients and other networking functions such as routing, and packet forwarding. Spectrum scarcity is the main challenge that limits the performance of WMNs. Cognitive radio is proposed to solve spectrum scarcity problem. In this paper, we consider a cognitive wireless mesh network where unlicensed users (secondary users, SUs) can access free spectrum that is allocated to spectrum owners (primary users, PUs). Although considerable research has been conducted on spectrum allocation, spectrum assignment is still considered an important challenging problem. This problem can be solved using cognitive radio technology that allows SUs to intelligently locate free bands and access them without interfering with PUs. Our scheme considers several heuristics for spectrum allocation. These heuristics include: channel error rate, PUs activities, channel capacity and channel switching time. Performance evaluation of the proposed scheme shows that the scheme is able to allocate the unused spectrum for SUs efficiently. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognitive%20radio" title="cognitive radio">cognitive radio</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20spectrum%20access" title=" dynamic spectrum access"> dynamic spectrum access</a>, <a href="https://publications.waset.org/abstracts/search?q=spectrum%20management" title=" spectrum management"> spectrum management</a>, <a href="https://publications.waset.org/abstracts/search?q=spectrum%20sharing" title=" spectrum sharing"> spectrum sharing</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20mesh%20networks" title=" wireless mesh networks"> wireless mesh networks</a> </p> <a href="https://publications.waset.org/abstracts/12925/spectrum-allocation-using-cognitive-radio-in-wireless-mesh-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12925.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">528</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">209</span> Influence of Composite Adherents Properties on the Dynamic Behavior of Double Lap Bonded Joint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Saleh">P.

Three fibers textures were considered: UD; 2.5D and 3D with same volume fiber then a parametric study based on changing the thickness and the type of fibers texture in 2.5D was accomplished. Moreover, adherents’ dissimilarity was also investigated. It was found that the main parameter influencing the behavior is the longitudinal stiffness of the adherents. An increase in the adherents’ longitudinal stiffness induces an increase in the maximum average shear stress in the adhesive layer and an improvement in the shear stress homogeneity within the joint.

Species distribution modeling has been widely employed to indicate probable areas of invasion and to guide management strategies. Drosophila sp. is native to Asia, but since 2015, it has invaded almost every country in the world, including Africa, Australia, India, and most recently, the Americas. The growth of this species of Drosophila suzukii has been rapidly multiplying and spreading in the last decade. In fact, we examine and model the potential geographical distribution of D. suzukii for both present and future scenarios. Finally, we determine the environmental variables that affect its distribution, as well as assess the risk of encroachment on protected areas. D.suzukii has the potential to expand its occurrence, especially on continents that have already been invaded. The predictive models obtained in this study indicate potential regions that could be at risk of invasion by D. suzukii, including protected areas. These results are important and can assist in the establishment of management plans to avoid the possible harm caused by biological invasions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=Drosophila%20suzukii" title=" Drosophila suzukii"> Drosophila suzukii</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20variables" title=" environmental variables"> environmental variables</a>, <a href="https://publications.waset.org/abstracts/search?q=host%20preference" title=" host preference"> host preference</a>, <a href="https://publications.waset.org/abstracts/search?q=host%20plant" title=" host plant"> host plant</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrition" title=" nutrition"> nutrition</a> </p> <a href="https://publications.waset.org/abstracts/146306/current-and-future-global-distribution-of-drosophila-suzukii" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146306.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">85</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">207</span> Investigation of Al/Si, Au/Si and Au/GaAs Interfaces by Positron Annihilation Spectroscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulnasser%20S.%20Saleh">Abdulnasser S.

The properties of these contacts can vary considerably depending on the nature of the interface with the semiconductor. Variable-energy positron annihilation spectroscopy has been applied to study interfaces in Al/Si, Au/Si, and Au/GaAs structures. A computational modeling by ROYPROF program is used to analyze Doppler broadening results in order to determine kinds of regions that positrons are likely to sample. In all fittings, the interfaces are found 1 nm thick and act as an absorbing sink for positrons diffusing towards them and may be regarded as highly defective. Internal electric fields were found to influence positrons diffusing to the interfaces and unable to force them cross to the other side. The materials positron affinities are considered in understanding such motion. The results of these theoretical fittings have clearly demonstrated the sensitivity of interfaces in any fitting attempts of analyzing positron spectroscopy data and gave valuable information about metal-semiconductor interfaces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interfaces" title="interfaces">interfaces</a>, <a href="https://publications.waset.org/abstracts/search?q=semiconductor" title=" semiconductor"> semiconductor</a>, <a href="https://publications.waset.org/abstracts/search?q=positron" title=" positron"> positron</a>, <a href="https://publications.waset.org/abstracts/search?q=defects" title=" defects "> defects </a> </p> <a href="https://publications.waset.org/abstracts/46927/investigation-of-alsi-ausi-and-augaas-interfaces-by-positron-annihilation-spectroscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46927.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">261</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">206</span> Role of Endonuclease G in Exogenous DNA Stability in HeLa Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vanja%20Misic">Vanja Misic</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20El-Mogy"> Mohamed El-Mogy</a>, <a href="https://publications.waset.org/abstracts/search?q=Yousef%20Haj-Ahmad"> Yousef Haj-Ahmad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Endonuclease G (EndoG) is a well conserved mitochondrio-nuclear nuclease with dual lethal and vital roles in the cell. The aim of our study was to examine whether EndoG exerts its nuclease activity on exogenous DNA substrates such as plasmid DNA (pDNA), considering their importance in gene therapy applications. The effects of EndoG knockdown on pDNA stability and levels of encoded reporter gene expression were evaluated in the cervical carcinoma HeLa cells. Transfection of pDNA vectors encoding short-hairpin RNAs (shRNAs) reduced levels of EndoG mRNA and nuclease activity in HeLa cells. In physiological circumstances, EndoG knockdown did not have an effect on the stability of pDNA or the levels of encoded transgene expression as measured over a four day time-course. However, when endogenous expression of EndoG was induced by an extrinsic stimulus, targeting of EndoG by shRNA improved the perceived stability and transgene expression of pDNA vectors. Therefore, EndoG is not a mediator of exogenous DNA clearance, but in non-physiological circumstances it may non-specifically cleave intracellular DNA regardless of its origin. These findings make it unlikely that targeting of EndoG is a viable strategy for improving the duration and level of transgene expression from non-viral DNA vectors in gene therapy efforts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EndoG" title="EndoG">EndoG</a>, <a href="https://publications.waset.org/abstracts/search?q=silencing" title=" silencing"> silencing</a>, <a href="https://publications.waset.org/abstracts/search?q=exogenous%20DNA%20stability" title=" exogenous DNA stability"> exogenous DNA stability</a>, <a href="https://publications.waset.org/abstracts/search?q=HeLa%20cells" title=" HeLa cells"> HeLa cells</a> </p> <a href="https://publications.waset.org/abstracts/13261/role-of-endonuclease-g-in-exogenous-dna-stability-in-hela-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13261.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">461</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">205</span> Review of Innovation Management Frameworks and Assessment Tools</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qiang%20Fu">Qiang Fu</a>, <a href="https://publications.waset.org/abstracts/search?q=Abu%20Saleh"> Abu Saleh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Research studies are highly fragmented when an innovation management framework is being discussed. With the aim to identify an innovation management framework/assessment tool suitable for small & medium enterprises (SMEs) in the service industry, this researcher critically reviewed existing innovation management frameworks and assessment models/tools and discovered a number of literature gaps. It is established that existing literature lacks generally agreed innovation management dimensions, commonly accepted knowledge creation through empirical studies on innovation management in SMEs, effective innovation management performance measurements, and studies on innovation management in the service industry, in particular in retail SMEs. As such, there is a dire need to develop an appropriate firm-level innovation management framework suitable for SMEs in the service industry for a future research project and further study. In addition, this researcher also discussed the significance of establishing such an innovation management framework. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=innovation%20management" title="innovation management">innovation management</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation%20management%20framework" title=" innovation management framework"> innovation management framework</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation%20management%20assessment%20tools" title=" innovation management assessment tools"> innovation management assessment tools</a>, <a href="https://publications.waset.org/abstracts/search?q=SMEs" title=" SMEs"> SMEs</a>, <a href="https://publications.waset.org/abstracts/search?q=service%20industry" title=" service industry"> service industry</a> </p> <a href="https://publications.waset.org/abstracts/135335/review-of-innovation-management-frameworks-and-assessment-tools" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135335.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">215</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">204</span> The Effect of Dynamic Eccentricity on the Stator Current Spectrum of 550 kW Induction Motor </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saleh%20Elawgali">Saleh Elawgali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to present the effect of the dynamic eccentricity on the stator currents of squirrel cage induction machines, the current spectrums of a 550 kW induction motor was calculated for the cases of full symmetry and dynamic eccentricity. The calculations presented in this paper are based on the Poly-Harmonic Model accounting for static and dynamic eccentricity, stator and rotor slotting, parallel branches as well as cage asymmetry. The calculations were followed by Fourier analysis of the stator currents in steady state operation. The paper presents the stator current spectrums for full symmetry and dynamic eccentricity cases, and demonstrates the harmonics present in each case. The effect of dynamic eccentricity is demonstrating via comparing the current spectrums related to dynamic eccentricity cases with the full symmetry one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=current%20spectrum" title="current spectrum">current spectrum</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20eccentricity" title=" dynamic eccentricity"> dynamic eccentricity</a>, <a href="https://publications.waset.org/abstracts/search?q=harmonics" title=" harmonics"> harmonics</a>, <a href="https://publications.waset.org/abstracts/search?q=Induction%20machine" title=" Induction machine"> Induction machine</a>, <a href="https://publications.waset.org/abstracts/search?q=slot%20harmonic%20zone." title=" slot harmonic zone."> slot harmonic zone.</a> </p> <a href="https://publications.waset.org/abstracts/9405/the-effect-of-dynamic-eccentricity-on-the-stator-current-spectrum-of-550-kw-induction-motor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9405.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">399</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">203</span> The Methodology of Flip Chip Using Astro Place and Route Tool</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rohaya%20Abdul%20Wahab">Rohaya Abdul Wahab</a>, <a href="https://publications.waset.org/abstracts/search?q=Raja%20Mohd%20Fuad%20Tengku%20Aziz"> Raja Mohd Fuad Tengku Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Nazaliza%20Othman"> Nazaliza Othman</a>, <a href="https://publications.waset.org/abstracts/search?q=Sharifah%20Saleh"> Sharifah Saleh</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabihah%20Razali"> Nabihah Razali</a>, <a href="https://publications.waset.org/abstracts/search?q=Rozaimah%20Baharim"> Rozaimah Baharim</a>, <a href="https://publications.waset.org/abstracts/search?q=Md%20Hanif%20Md%20Nasir"> Md Hanif Md Nasir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper will discuss flip chip methodology, in which I/O pads, standard cells, macros and bump cells array are placed in the floorplan, then routed using Astro place and route tool.

It is predicted that there will be 9.3 billion people on Earth in 2050 and that over two-thirds of this population will be city dwellers. Moreover, in larger cities worldwide, mass transportation systems, including underground systems, have grown to account for the majority of travel in those settings. Underground networks are vulnerable to fires, however, endangering travellers’ safety, with various examples of fire outbreaks in this setting. This study aims to increase knowledge of the impacts of extreme climatic conditions on fires, including the role of the high ambient temperatures experienced in Middle Eastern countries and specifically in Saudi Arabia. This is an element that is not always included when assessments of fire safety are made (considering visibility, temperatures, and flows of smoke). This paper focuses on a tunnel within Riyadh’s underground system as a case study and includes simulations based on computational fluid dynamics using ANSYS Fluent, which investigates the impact of various ventilation systems while identifying smoke density, speed, pressure and temperatures within this tunnel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fire" title="fire">fire</a>, <a href="https://publications.waset.org/abstracts/search?q=subway%20tunnel" title=" subway tunnel"> subway tunnel</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20ventilation" title=" mechanical ventilation"> mechanical ventilation</a>, <a href="https://publications.waset.org/abstracts/search?q=smoke" title=" smoke"> smoke</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=harsh%20weather" title=" harsh weather"> harsh weather</a> </p> <a href="https://publications.waset.org/abstracts/158423/computational-fluid-dynamics-simulation-to-study-the-effect-of-ambient-temperature-on-the-ventilation-in-a-metro-tunnel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158423.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">132</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">200</span> Crowdfunding for Saudi Arabia Green Projects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saleh%20Komies">Saleh Komies</a>, <a href="https://publications.waset.org/abstracts/search?q=Mona%20Alharbi"> Mona Alharbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Razan%20Alhayyani"> Razan Alhayyani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mozah%20Almulhim"> Mozah Almulhim</a>, <a href="https://publications.waset.org/abstracts/search?q=Roseanne%20Khawaja"> Roseanne Khawaja</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Alradhi"> Ahmed Alradhi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the proposed solutions that faces some challenges is encouraging sustainable energy consumption across Saudi Arabia through crowdfunding platforms. To address these challenges, we need to determine the level of awareness of crowdfunding and green projects, as well as the preferences and willingness of Saudis to utilize crowdfunding as an alternative funding source for green projects in Saudi Arabia. In this study, we aim to determine the influence of environmental awareness and concern on the propensity to crowdfund green projects. The survey is being conducted as part of environmental initiatives to assess public perceptions and opinions on crowdfunding green projects in Saudi Arabia. A total of 450 responses to an online questionnaire distributed via convenience and snowball sampling were utilized for data analysis. The survey reveals that Saudis have a low understanding of crowdfunding concepts and a relatively high understanding of implementing green projects. The public is interested in crowdfunding green projects if there is a return on investment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crowdfunding" title="crowdfunding">crowdfunding</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20projects" title=" green projects"> green projects</a>, <a href="https://publications.waset.org/abstracts/search?q=awareness" title=" awareness"> awareness</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20Arabia" title=" Saudi Arabia"> Saudi Arabia</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a>, <a href="https://publications.waset.org/abstracts/search?q=solar" title=" solar"> solar</a>, <a href="https://publications.waset.org/abstracts/search?q=wind" title=" wind"> wind</a> </p> <a href="https://publications.waset.org/abstracts/155924/crowdfunding-for-saudi-arabia-green-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155924.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">99</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">199</span> Innovative Method for Treating Oil-Produced Water with Low Operating Cost</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20Salman">Maha Salman</a>, <a href="https://publications.waset.org/abstracts/search?q=Gada%20Al-Nuwaibit"> Gada Al-Nuwaibit</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Al-Haji"> Ahmed Al-Haji</a>, <a href="https://publications.waset.org/abstracts/search?q=Saleh%20Al-Haddad"> Saleh Al-Haddad</a>, <a href="https://publications.waset.org/abstracts/search?q=Abbas%20Al-Mesri"> Abbas Al-Mesri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mansour%20Al-Rugeeb"> Mansour Al-Rugeeb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The high salinity of oil-produced water and its complicated chemical composition, makes designing a suitable treatment system for oil-produced water is extremely difficult and costly.

For evaluation of immunization, we determined the kinetics of the distribution of Toxoplasma and parasite load in different tissues of mice immunized by ESAs. Methods: In this experimental study, 36 mice in case (n= 18) and control (n= 18) groups were immunized with ESAs and PBS, respectively. After 2 weeks, mice were challenged intraperitoneally with Toxoplasma virulent RH strain. Blood and different tissues (brain, spleen, liver, heart, kidney, and muscle) were collected daily after challenge (1, 2, 3 and last day before death). Parasite load was calculated using Real time QPCR targeted at the B1 gene. Results: ESAs as vaccine in different tissues showed various effects. However, infected mice which received the vaccine in comparison with control group, displayed a drastically decreasing in parasite burden, in their blood and tissues (P= 0.000). Conclusion: These results indicated that ESAs with reduction of parasite load in different tissues of host could be evaluable candidate for the development of immunization strategies against toxoplasmosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=parasitic%20load" title="parasitic load">parasitic load</a>, <a href="https://publications.waset.org/abstracts/search?q=murine%20toxoplasmosis" title=" murine toxoplasmosis"> murine toxoplasmosis</a>, <a href="https://publications.waset.org/abstracts/search?q=immunization" title=" immunization"> immunization</a>, <a href="https://publications.waset.org/abstracts/search?q=excretory-secretory%20antigens" title=" excretory-secretory antigens"> excretory-secretory antigens</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20time%20QPCR" title=" real time QPCR"> real time QPCR</a> </p> <a href="https://publications.waset.org/abstracts/15697/determination-of-parasitic-load-in-different-tissues-of-murine-toxoplasmosis-after-immunization-by-excretory-secretory-antigens-using-real-time-qpcr" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15697.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">444</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">197</span> Archaeological Study of Statues of King Thutmosis III from Luxor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Mamdouh">Ahmed Mamdouh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The era of Thutmosis III represents a transitional period between the art of the Thutmoside art and the Amarna period, so we intend to declare that it serves as the cradle of Amarna art. The study will examine the Statues of king Thutmose III that was discovered in Luxor by an Egyptian mission. These Statues have been transferred to the Conservation Center of the Grand Egyptian Museum (GEM) to be conserved and made ready to bedisplayed at the new museum (the project of the century). We focus upon three Statues (GEM numbers 45863, 45864, 45865), chosen because they relate to different years of the king's reign. These Statues were all made of granite. The first one is a Kneeling statue representing the god Amun showing king Thutmose III offering to the goddess Hathor. The second is decorated with king Thutmose III with the red crown, between the goddess Hathor and the royal wife, Nefertari. The third shows the king offering NW vessels and bread to the god Seker. Each Statue is divided into registers containing a description and decorated with scenes of the king presenting offerings to gods. Methodology: The proposed study will focus on the development which happened sequentially according to differences that occur in each Statue. We will use comparative research to determine the workshops of these statues, whether one or several, and what are the distinguishing features of each one. We will examine what innovations the artisans added to royal art. The description and the texts will be translated with linguistic comments. This research focuses on text analyses and technology. Paleographic information found on these objects includes the names and titles of the king. Conclusion: This research focuses on text analyses and technology. The study aims to create a manual that may help in dating the artwork of Thutmosis III. This research will be beneficial and useful for heritage and ancient civilizations, particularly when we talk about opening museums like the Grand Egyptian museum, which will exhibit a collection of statues. Indeed this kind of study will open a new destination in order to know how to identify these collections and how to exhibit them commensurate with the nature of ancient Egyptian history and heritage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=archaeological%20study" title="archaeological study">archaeological study</a>, <a href="https://publications.waset.org/abstracts/search?q=Giza" title=" Giza"> Giza</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20kingdom" title=" new kingdom"> new kingdom</a>, <a href="https://publications.waset.org/abstracts/search?q=statues" title=" statues"> statues</a>, <a href="https://publications.waset.org/abstracts/search?q=royal%20art" title=" royal art"> royal art</a> </p> <a href="https://publications.waset.org/abstracts/163399/archaeological-study-of-statues-of-king-thutmosis-iii-from-luxor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163399.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">68</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">196</span> Metal-Semiconductor-Metal Photodetector Based on Porous In0.08Ga0.92N</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saleh%20H.%20Abud">Saleh H.

Nanoporous structures of n-type In0.08Ga0.92N/AlN/Si thin films were synthesized by photoelectrochemical (PEC) etching at a ratio of 1:4 of HF:C2H5OH solution for 15 min. The structural and optical properties of pre- and post-etched thin films were investigated. Field emission scanning electron microscope and atomic force microscope images showed that the pre-etched thin film has a sufficiently smooth surface over a large region and the roughness increased for porous film. Blue shift has been observed in photoluminescence emission peak at 300 K for porous sample. The photoluminescence intensity of the porous film indicated that the optical properties have been enhanced. A high work function metals (Pt and Ni) were deposited as a metal contact on the porous films. The rise and recovery times of the devices were investigated at 390 nm chopped light. Finally, the sensitivity and quantum efficiency were also studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=porous%20InGaN" title="porous InGaN">porous InGaN</a>, <a href="https://publications.waset.org/abstracts/search?q=photoluminescence" title=" photoluminescence"> photoluminescence</a>, <a href="https://publications.waset.org/abstracts/search?q=SMS%20photodetector" title=" SMS photodetector"> SMS photodetector</a>, <a href="https://publications.waset.org/abstracts/search?q=atomic%20force%20microscopy" title=" atomic force microscopy"> atomic force microscopy</a> </p> <a href="https://publications.waset.org/abstracts/4022/metal-semiconductor-metal-photodetector-based-on-porous-in008ga092n" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4022.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">489</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">195</span> Identification of Promising Infant Clusters to Obtain Improved Block Layout Designs </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustahsan%20Mir">Mustahsan Mir</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Hassanin"> Ahmed Hassanin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20A.%20Al-Saleh"> Mohammed A.

A number of heuristics and some analytical and hybrid techniques have been published to solve this problem. This paper presents an efficient high-quality building-block layout design technique especially suited for solving large-size problems. The higher efficiency and improved quality of optimized solutions are made possible by introducing the concept of Promising Infant Clusters in a constructive placement procedure. The results presented in the paper demonstrate the improved performance of the presented technique for benchmark problems in comparison with published heuristic, analytic, and hybrid techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=block%20layout%20problem" title="block layout problem">block layout problem</a>, <a href="https://publications.waset.org/abstracts/search?q=building-block%20layout%20design" title=" building-block layout design"> building-block layout design</a>, <a href="https://publications.waset.org/abstracts/search?q=CAD" title=" CAD"> CAD</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=search%20techniques" title=" search techniques"> search techniques</a> </p> <a href="https://publications.waset.org/abstracts/38727/identification-of-promising-infant-clusters-to-obtain-improved-block-layout-designs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38727.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">386</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">194</span> A Comprehensive Study of Accounting for Growth in China and India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yousef%20Rostami%20Gharainy">Yousef Rostami Gharainy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We look at the late financial exhibitions of China and India utilizing a simple growth accounting framework that creates assessments of the commitment of work, capital, training, and aggregate variable profitability for the three parts of agribusiness, industry, and administrations and in addition for the total economy. Our examination consolidates late information updates in both nations and incorporates broad examination of the basic information arrangement. The development records demonstrate a generally square with division in each nation between the commitments of capital gathering and TFP to development in yield every specialist over the period 1980-2007, and an increasing speed of development when the period is separated at 1993. Be that as it may, the size of yield development in China is generally twofold that of India at the total level, and additionally higher in each of the three segments in both sub-periods. In China the post-1993 increasing speed was amassed generally in industry, which contributed about 61 percent of China’s total efficiency development. Interestingly, 48 percent of the development in India in the second sub-period came in administrations. Reallocation of specialists from farming to industry and administrations has contributed 1.3 rate focuses to efficiency development in every nation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=China" title="China">China</a>, <a href="https://publications.waset.org/abstracts/search?q=India" title=" India"> India</a>, <a href="https://publications.waset.org/abstracts/search?q=growth%20accounting%20framework" title=" growth accounting framework"> growth accounting framework</a>, <a href="https://publications.waset.org/abstracts/search?q=work" title=" work"> work</a>, <a href="https://publications.waset.org/abstracts/search?q=capital" title=" capital"> capital</a>, <a href="https://publications.waset.org/abstracts/search?q=training" title=" training"> training</a>, <a href="https://publications.waset.org/abstracts/search?q=aggregate%20variable%20profitability" title=" aggregate variable profitability"> aggregate variable profitability</a> </p> <a href="https://publications.waset.org/abstracts/32673/a-comprehensive-study-of-accounting-for-growth-in-china-and-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32673.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">297</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">193</span> Double-Diffusive Natural Convection with Various Partially Heated and Salted Sources Arrangements in an Open Cavity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Norazam%20Arbin">Norazam Arbin</a>, <a href="https://publications.waset.org/abstracts/search?q=Habibis%20Saleh"> Habibis Saleh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Alsabery"> Ammar Alsabery</a>, <a href="https://publications.waset.org/abstracts/search?q=Ishak%20Hashim"> Ishak Hashim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Double-diffusive natural convection in an open top cavity with partial vertical heating and salting sources is investigated numerically. Different temperatures and concentrations are applied at the source location on the right and left walls while the other remains adiabatic except at the open top surface. Various combinations of sources arrangements are imposed at the vertical walls in order to observe the significant impact to the convection. An iterative finite different method is used to solve the dimensionless governing equations. The effects of Marangoni number and sources arrangements on the contours of streamlines, isotherms, and concentrations are visualized as the outcome of the numerical solutions. The average Nusselt and Sherwood number are presented for various sources arrangements. It is clearly observed that the sources arrangements gave major impact on the heat and mass transfer rates. A horizontal-like pattern is found for sources arrangements that near the top-free surface. <p class="card-text"><strong>Keywords:</strong> <a
