RA is the most common form of autoimmune arthritis, affecting more than 1.3 million Americans. Of these, about 75% are women. Materials and Methods: This study was formed due to the misconception about ANA test, which is frequently performed with methods based upon solid phase as ELISA. This experiment was conducted on 430 patients, with clinical symptoms that are likely affected with rheumatic diseases, simultaneously by means of ANA and FANA. Results: 36 cases (8.37%) of patients, despite positive ANA, have demonstrated negative results via Indirect Immunofluorescence Assay (IIFA), (false positive). 116 cases (27%) have demonstrated negative ANA results, by means of the ELISA technique, although they had positive IIFA results. Conclusion: Other advantages of IIFA are antibody titration and specific pattern detection that have the capability of distinguishing positive dsDNA results. According to the restrictions and false negative cases, in patients, IIFA test is highly recommended for these disease's diagnosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autoimmune%20disease" title="autoimmune disease">autoimmune disease</a>, <a href="https://publications.waset.org/abstracts/search?q=IIFA" title=" IIFA"> IIFA</a>, <a href="https://publications.waset.org/abstracts/search?q=EIA" title=" EIA"> EIA</a>, <a href="https://publications.waset.org/abstracts/search?q=rheumatic%20disease" title=" rheumatic disease"> rheumatic disease</a> </p> <a href="https://publications.waset.org/abstracts/23763/ana-negative-but-fana-positive-patients-with-clinical-symptoms-of-rheumatic-disease-the-suggestion-for-clinicians" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23763.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">499</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">20</span> Serological Assay and Genotyping of Hepatitis C Virus in Infected Patients in Zanjan Province</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Esmaeilzadeh">Abdolreza Esmaeilzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Erfanmanesh"> Maryam Erfanmanesh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sousan%20Ghasemi"> Sousan Ghasemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Farzaneh%20Mohammadi"> Farzaneh Mohammadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Hepatitis C Virus (HCV), a public health problem, is an enveloped, single-stranded RNA virus and a member of the Hepacivirus genus of the Flaviviridae family. Liver cancer, cirrhosis, and end-stage liver are the outcomes of chronic infection with HCV. HCV isolates show significant heterogeneity in genetics around the world. Therefore, determining HCV genotypes is a vital step in determining prognosis and planning therapeutic strategies. Materials and Methods: Serum samples of 136 patients were collected and analyzed for anti-HCV antibodies using ELISA (The enzyme-linked immunosorbent assay) method. Then, positive samples were exposed to RT-PCR, which was performed under standard condition. Afterwards, they investigated for genotyping using allele-specific PCR (AS-PCR), and HCV genotype 2.0 line probe assay (LiPA). Results: Samples indicated 216 bp bands on 2% agarose gel. Analyses of the results demonstrated that the most dominant subtype was 3a with frequency of 38.26% in Zanjan Province followed by subtypes of 1b, 1a, 2, and 4 with frequencies of 25.73%, 22.05%, 5.14%, and 4.41%, respectively. The frequency of unknown HCV genotypes was 4.41%. Conclusions: According to the results, it was found that HCV high prevalent genotype in Zanjan is subtype 3a. Analysis of the results provides identification of certain HCV genotypes, and these valuable findings could affect the type and duration of the treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-HCV%20antibody" title="anti-HCV antibody">anti-HCV antibody</a>, <a href="https://publications.waset.org/abstracts/search?q=Hepatitis%20C%20Virus%20%28HCV%29" title=" Hepatitis C Virus (HCV)"> Hepatitis C Virus (HCV)</a>, <a href="https://publications.waset.org/abstracts/search?q=genotype" title=" genotype"> genotype</a>, <a href="https://publications.waset.org/abstracts/search?q=RT-PCR" title=" RT-PCR"> RT-PCR</a>, <a href="https://publications.waset.org/abstracts/search?q=AS-PCR" title=" AS-PCR "> AS-PCR </a> </p> <a href="https://publications.waset.org/abstracts/23761/serological-assay-and-genotyping-of-hepatitis-c-virus-in-infected-patients-in-zanjan-province" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23761.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">19</span> Preparation of Regional Input-Output Table for Fars Province in 2011: GRIT1Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Akbarzadeh">Maryam Akbarzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=F.%20Esmaeilzadeh"> F.

Modeling was performed for three different core lengths with different production and injection flow rates in both vertical and horizontal cases. According to the results, the final condensate in place value in the natural depletion process is approximately independent of the production rate for a given pressure drop. The final condensate in place value is lower in vertical cases compared to horizontal cases. An increase in the injection flow rate leads to a decrease in the percentage of gascondensate recovery. In cores of equal length, gas condensate recovery percent is higher in vertical cases in comparison to horizontal cases. For a constant injection rate, decreasing the core length leads to a decrease in gas condensate recovery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reservoir%20simulation" title="reservoir simulation">reservoir simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=methane%20injection" title=" methane injection"> methane injection</a>, <a href="https://publications.waset.org/abstracts/search?q=enhanced%20condensate%20recovery" title=" enhanced condensate recovery"> enhanced condensate recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=reservoir%20core" title=" reservoir core"> reservoir core</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a> </p> <a href="https://publications.waset.org/abstracts/153704/thermodynamic-modeling-of-methane-injection-in-gas-condensate-reservoir-core-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153704.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">16</span> Evaluating the effects of Gas Injection on Enhanced Gas-Condensate Recovery and Reservoir Pressure Maintenance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20S.%20Alavi">F.

Some experimental data were used to tune the Peng-Robinson equation of state for this case. Different scenarios of gas injection at current reservoir pressure and at abandonment reservoir pressure had been considered with different gas compositions. Methane, carbon dioxide, nitrogen and two other gases with specified compositions were considered as potential gases for injection. According to the obtained results, nitrogen leads to highest pressure maintenance in the reservoir but methane results in highest condensate recovery among the selected injection gases. At low injection rates, condensate recovery percent is strongly affected by gas injection rate but this dependency shifts to zero at high injection rates. Condensate recovery is higher in all cases of injection at current reservoir pressure than injection at abandonment pressure. Using a constant injection rate, increasing the production well bottom hole pressure results in increasing the condensate recovery percent and time of gas breakthrough. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gas-condensate%20reservoir" title="gas-condensate reservoir">gas-condensate reservoir</a>, <a href="https://publications.waset.org/abstracts/search?q=case-study" title=" case-study"> case-study</a>, <a href="https://publications.waset.org/abstracts/search?q=compositional%20modelling" title=" compositional modelling"> compositional modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=enhanced%20condensate%20recovery" title=" enhanced condensate recovery"> enhanced condensate recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20injection" title=" gas injection"> gas injection</a> </p> <a href="https://publications.waset.org/abstracts/153670/evaluating-the-effects-of-gas-injection-on-enhanced-gas-condensate-recovery-and-reservoir-pressure-maintenance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153670.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">195</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">15</span> Preparation and Characterization of Nanocrystalline Cellulose from Acacia mangium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samira%20Gharehkhani">Samira Gharehkhani</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Farid%20Seyed%20Shirazi"> Seyed Farid Seyed Shirazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Gharehkhani"> Abdolreza Gharehkhani</a>, <a href="https://publications.waset.org/abstracts/search?q=Hooman%20Yarmand"> Hooman Yarmand</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Badarudin"> Ahmad Badarudin</a>, <a href="https://publications.waset.org/abstracts/search?q=Rushdan%20Ibrahim"> Rushdan Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Salim%20Newaz%20Kazi"> Salim Newaz Kazi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nanocrystalline cellulose (NCC) were prepared by acid hydrolysis and ultrasound treatment of bleached Acacia mangium fibers.

In order to reduce this force and consequently reduce scour hole depth, flip buckets may equip by dents. The minimum scour hole depth might be occurred by optimization of dents (number, shape, placement) on flip buckets. In this study, a comprehensive physical model has been developed and various options for dents have been investigated. The experimental data for each dent option such as scour hole depth, angle of impingement jet, piezometric pressure in tail-water and jet trajectory have been measured for various discharges.

In addition to the automation industry, the Internet of Things (IoT) has been used in environmental issues and has provided the possibility of communication between different devices for data collection and exchange. Water quality depends on many factors which are essential for maintaining the minimum sustainability of water. Regarding the great dependence of fishes on the quality of the aquatic environment, water quality can directly affect their activity. Therefore, monitoring water quality is an important issue to consider, especially in the fish farming industry. The conventional method of water quality testing is to collect water samples manually and send them to a laboratory for testing and analysis. This time-consuming method is a waste of manpower and is not cost-effective. The water quality measurement system implemented in this project monitors water quality in real-time through various sensors (parameters: water temperature, water level, dissolved oxygen, humidity and ambient temperature, water turbidity, PH). The Wi-Fi module, ESP8266, transmits data collected by sensors wirelessly to ThingSpeak and the smartphone app. Also, with the help of these instantaneous data, water temperature and water level can be controlled by using a heater and a water pump, respectively. This system can have a detailed study of the pollution and condition of water resources and can provide an environment for safe fish farming. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dissolved%20oxygen" title="dissolved oxygen">dissolved oxygen</a>, <a href="https://publications.waset.org/abstracts/search?q=IoT" title=" IoT"> IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=ThingSpeak" title=" ThingSpeak"> ThingSpeak</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20level" title=" water level"> water level</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a>, <a href="https://publications.waset.org/abstracts/search?q=WiFi%20module" title=" WiFi module"> WiFi module</a> </p> <a href="https://publications.waset.org/abstracts/142252/real-time-water-quality-monitoring-and-control-system-for-fish-farms-based-on-iot" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142252.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">194</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">12</span> Identifying the Factors Influencing the Success of the Centers for Distance Knowledge Sharing in Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Noroozi%20Chakoli">Abdolreza Noroozi Chakoli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to examine the impact of five effective factors on the success of the managers of distance knowledge sharing centers in Iran.

ANOVA test, Scheffe test, and Pearson's correlation test were used to analyze the data. The findings confirmed the effect of all 5 factors on the success of these centers. However, their effects are not the same on each factor. The results show each of these factors is not only individually but also together affect the success of centers for distance knowledge sharing.

Thus, rapid response from the manufacturer is very crucial. Tool path strategy of milling process has a direct influence on the surface roughness and lead time of medical implant. High-speed milling as promised process would improve the machined surface quality, but conventional or super-abrasive grinding still required which imposes some drawbacks such as additional costs and time. Currently, many CAD/CAM software offers some different tool path strategies to milling free form surfaces. Nevertheless, the users must identify how to choose the strategies according to cutting tool geometry, geometry complexity, and their effects on the machined surface. This study investigates the effect of different tool path strategies for milling a proximal humerus head during finishing operation on stainless steel 316L. Experiments have been performed using MAHO MH700 S vertical milling machine and four machining strategies, namely, spiral outward, spiral inward, and radial as well as zig-zag. In all cases, the obtained surfaces were analyzed in terms of roughness and dimension accuracy compared with those obtained by simulation. The findings provide evidence that surface roughness, dimensional accuracy, and machining time have been affected by the considered tool path strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CAD%2FCAM%20software" title="CAD/CAM software">CAD/CAM software</a>, <a href="https://publications.waset.org/abstracts/search?q=milling" title=" milling"> milling</a>, <a href="https://publications.waset.org/abstracts/search?q=orthopedic%20implants" title=" orthopedic implants"> orthopedic implants</a>, <a href="https://publications.waset.org/abstracts/search?q=tool%20path%20strategy" title=" tool path strategy"> tool path strategy</a> </p> <a href="https://publications.waset.org/abstracts/76801/the-effect-of-tool-path-strategy-on-surface-and-dimension-in-high-speed-milling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76801.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">213</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">10</span> Prediction Fluid Properties of Iranian Oil Field with Using of Radial Based Neural Network </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Memari">Abdolreza Memari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article in order to estimate the viscosity of crude oil,a numerical method has been used.

Then the crude oil's viscosity is estimated by using KHAN model and roller ball method. After that using these data that include efficient conditions in measuring viscosity, the estimated viscosity by the presented method, a radial based neural method, is taught. This network is a kind of two layered artificial neural network that its stimulation function of hidden layer is Gaussian function and teaching algorithms are used to teach them. After teaching radial based neural network, results of experimental method and artificial intelligence are compared all together. Teaching this network, we are able to estimate crude oil's viscosity without using KHAN model and experimental conditions and under any other condition with acceptable accuracy.

Deep drawing is regarded as a common metal sheet manufacturing process is used extensively in the modern industry, particularly automobile industry. To investigate the potential of deep drawing characteristic of materials, steel sheet anisotropy is studied and expressed as R-Value. The TRIP steels have a multi-phase microstructure consisting typically of ferrite, bainite and retained austenite. The retained austenite appears to be the most effective phase in the microstructure of the TRIP steels. In the present research, Taguchi method has been employed to study investigates the effect of austempering temperature parameters on the anisotropy property of the TRIP steel. To achieve this purpose, a steel with chemical composition of 0.196C -1.42Si-1.41Mn, has been used and annealed at 810oC, and then austempered at 340-460oC for 3, 6, and 9 minutes. The results shows that the austempering temperature has a direct relationship with R-value, respectively. With increasing austempering temperature, residual austenite grain size increases as well as increased solubility, which increases the amount of R-value. According to the results of the Taguchi method, austempering temperature’s p-value less than 0.05 is due to effective on R-value. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taguchi%20method" title="Taguchi method">Taguchi method</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20rolling" title=" hot rolling"> hot rolling</a>, <a href="https://publications.waset.org/abstracts/search?q=thermomechanical%20process" title=" thermomechanical process"> thermomechanical process</a>, <a href="https://publications.waset.org/abstracts/search?q=anisotropy" title=" anisotropy"> anisotropy</a>, <a href="https://publications.waset.org/abstracts/search?q=R-value" title=" R-value"> R-value</a> </p> <a href="https://publications.waset.org/abstracts/33313/the-effect-of-austempering-temperature-on-anisotropy-of-trip-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33313.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">326</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">8</span> Design and Control of a Knee Rehabilitation Device Using an MR-Fluid Brake</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mina%20Beheshti">Mina Beheshti</a>, <a href="https://publications.waset.org/abstracts/search?q=Vida%20Shams"> Vida Shams</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Esfandiari"> Mojtaba Esfandiari</a>, <a href="https://publications.waset.org/abstracts/search?q=Farzaneh%20Abdollahi"> Farzaneh Abdollahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Ohadi"> Abdolreza Ohadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Most of the people who survive a stroke need rehabilitation tools to regain their mobility. The core function of these devices is a brake actuator. The goal of this study is to design and control a magnetorheological brake which can be used as a rehabilitation tool. In fact, the fluid used in this brake is called magnetorheological fluid or MR that properties can change by variation of the magnetic field. The braking properties can be set as control by using this feature of the fluid. In this research, different MR brake designs are first introduced in each design, and the dimensions of the brake have been determined based on the required torque for foot movement. To calculate the brake dimensions, it is assumed that the shear stress distribution in the fluid is uniform and the fluid is in its saturated state. After designing the rehabilitation brake, the mathematical model of the healthy movement of a healthy person is extracted. Due to the nonlinear nature of the system and its variability, various adaptive controllers, neural networks, and robust have been implemented to estimate the parameters and control the system. After calculating torque and control current, the best type of controller in terms of error and control current has been selected. Finally, this controller is implemented on the experimental data of the patient's movements, and the control current is calculated to achieve the desired torque and motion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title="rehabilitation">rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetorheological%20fluid" title=" magnetorheological fluid"> magnetorheological fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=knee" title=" knee"> knee</a>, <a href="https://publications.waset.org/abstracts/search?q=brake" title=" brake"> brake</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptive%20control" title=" adaptive control"> adaptive control</a>, <a href="https://publications.waset.org/abstracts/search?q=robust%20control" title=" robust control"> robust control</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20network%20control" title=" neural network control"> neural network control</a>, <a href="https://publications.waset.org/abstracts/search?q=torque%20control" title=" torque control"> torque control</a> </p> <a href="https://publications.waset.org/abstracts/134338/design-and-control-of-a-knee-rehabilitation-device-using-an-mr-fluid-brake" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134338.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">151</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">7</span> Sun Protection Factor (SPF) Determination of Sericin Cream and Niosomal Gel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farzad%20Doostishoar">Farzad Doostishoar</a>, <a href="https://publications.waset.org/abstracts/search?q=Abbas%20Pardakhty"> Abbas Pardakhty</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Hassanzadeh"> Abdolreza Hassanzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sudeh%20salarpour"> Sudeh salarpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Sharif"> Elham Sharif</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Sericin is a protein extracted from silk and has antioxidant, antimicrobial, antineoplastic, wound healing and moisturizing properties. Different cosmetic formulation of sericin is available in different countries such as Japan and the other south-eastern Asian countries. We formulated and evaluated the sunscreen properties of topical formulations of sericin by an in vitro method. Method: Niosomes composed of sorbitan palmitate (Span 40), polysorbate 40 (Tween 40) and cholesterol (300 µmol, 3.5:3.5:3 molar ratio) were prepared by film hydration technique. Sericin was dissolved in normal saline and the lipid hydration was carried out at 60°C and the niosomes were incorporated in a Carbomer gel base. A W/O cream was also prepared and the release of sericin was evaluated by using Franz diffusion cell. Particle size analysis, sericin encapsulation efficiency measurement, morphological studies and stability evaluation were done in niosomal formulations. SPF was calculated by using Transpore tape in vitro method for both formulations. Results: Niosomes had high stability during 6 months storage at 4-8°C. The mean volume diameter of niosomes was less than 7 µm which is ideal for sustained release of drugs in topical formulations. The SPF of niosomal gel was 25 and higher than sericin cream with a diffusion based release pattern of active material. Conclusion: Sericin can be successfully entrapped in niosomes with sustained release pattern and relatively high SPF. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sericin" title="sericin">sericin</a>, <a href="https://publications.waset.org/abstracts/search?q=niosomes" title=" niosomes"> niosomes</a>, <a href="https://publications.waset.org/abstracts/search?q=sun%20protection%20factor" title=" sun protection factor"> sun protection factor</a>, <a href="https://publications.waset.org/abstracts/search?q=cream" title=" cream"> cream</a>, <a href="https://publications.waset.org/abstracts/search?q=gel" title=" gel"> gel</a> </p> <a href="https://publications.waset.org/abstracts/25326/sun-protection-factor-spf-determination-of-sericin-cream-and-niosomal-gel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25326.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">500</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">6</span> Conceptual Modeling of the Relationship between Project Management Practices and Knowledge Absorptive Capacity Using Interpretive Structural Modeling Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Abdolreza%20Mosavi">Seyed Abdolreza Mosavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Babakhan"> Alireza Babakhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Sadat%20Hoseinifard"> Elham Sadat Hoseinifard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Knowledge-based firms need to design mechanisms for continuous absorptive and creation of knowledge in order to ensure their survival in the competitive arena and to follow the path of development.

Accordingly, effective corrosion inhibitors should be developed based on natural resources to mitigate sour corrosion in the oil and gas industry. Here, Arabic gum was employed as an eco-friendly precursor for the synthesis of innovative polyurethanes designed as highly efficient corrosion inhibitors for sour oilfield solutions. A comprehensive assessment, combining experimental and computational analyses, was conducted to evaluate the inhibitory performance of the inhibitor. Electrochemical measurements demonstrated that a concentration of 200 mM of the inhibitor offered substantial protection to mild steel against sour corrosion, yielding inhibition efficiencies of 98% and 95% at 25 ºC and 60 ºC, respectively. Additionally, the presence of the inhibitor led to a smoother steel surface, indicating the adsorption of polyurethane molecules onto the metal surface. X-ray photoelectron spectroscopy results further validated the chemical adsorption of the inhibitor on mild steel surfaces. Scanning Kelvin probe microscopy revealed a shift in the potential distribution of the steel surface towards negative values, indicating inhibitor adsorption and corrosion process inhibition. Molecular dynamic simulation indicated high adsorption energy values for the inhibitor, suggesting its spontaneous adsorption onto the Fe (110) surface. These findings underscore the potential of Arabic gum as a viable resource for the development of polyurethanes under mild conditions, serving as effective corrosion inhibitors for sour solutions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20effect" title="environmental effect">environmental effect</a>, <a href="https://publications.waset.org/abstracts/search?q=Arabic%20gum" title=" Arabic gum"> Arabic gum</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion%20inhibitor" title=" corrosion inhibitor"> corrosion inhibitor</a>, <a href="https://publications.waset.org/abstracts/search?q=sour%20corrosion" title=" sour corrosion"> sour corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics%20simulation" title=" molecular dynamics simulation"> molecular dynamics simulation</a> </p> <a href="https://publications.waset.org/abstracts/177782/eco-friendly-polymeric-corrosion-inhibitor-for-sour-oilfield-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177782.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">62</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">4</span> Deuterium Effect on the Growth of the Fungus Aspergillus Fumigatus and Candida Albicans</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farzad%20Doostishoar">Farzad Doostishoar</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Hasanzadeh"> Abdolreza Hasanzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Amin%20Ayatolahi%20Mousavi"> Seyed Amin Ayatolahi Mousavi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction and Goals: Deuterium has different action from its isotopes hydrogen in chemical reactions and biochemical processes. It is not a significant difference in heavier atoms between the behavior of heavier isotope and the lighter One but for very lighter atoms it is significant . According to that most of the weight of all creatures body is water natural rate can be significant. In this article we want to study the effect of reduced deuterium on the fungus cell. If we saw the dependence of deuterium concentration of environment on the cells growth we can test this in invivo models too. Methods: First we measured deuterium concentration of the distillated water this analyze was operated by Arak’s heavy water company. Then the deuterium was diluted to ½ ¼ 1/8 1/16 by adding water free of deuterium for making media. In tree of samples the deuterium concentration was increased by adding D2O up to 10,50,100 times more concentrated. For candida albicans growth we used sabor medium and for aspergillus fomigatis growth we used sabor medium containing chloramphenicol. After culturing the funguses species we put the mediums for each species in the shaker incubator for 10 days in 25 centigrade. In different days and times the plates were studied morphologically and some microscopic characteristics were studied too. This experiments and cultures were repeated 3 times. Results: Statistical analyzes by paired-sample T test showed that aspergilus fomigatoos growth was decreased in concentration of 72 ppm( half deuterium concentration of negative control) significantly. In deuterium concentration reduction the growth reduce into the negative control significantly. The project results showed that candida albicans was sensitive to reduce and decrease of the deuterium in all concentrations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deuterium" title="deuterium">deuterium</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20cell" title=" cancer cell"> cancer cell</a>, <a href="https://publications.waset.org/abstracts/search?q=growth" title=" growth"> growth</a>, <a href="https://publications.waset.org/abstracts/search?q=candida%20albicans" title=" candida albicans"> candida albicans</a> </p> <a href="https://publications.waset.org/abstracts/25328/deuterium-effect-on-the-growth-of-the-fungus-aspergillus-fumigatus-and-candida-albicans" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25328.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">401</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">3</span> The Assessment Groundwater Geochemistry of Some Wells in Rafsanjan Plain, Southeast of Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Milad%20Mirzaei%20Aminiyan">Milad Mirzaei Aminiyan</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Akhgar"> Abdolreza Akhgar</a>, <a href="https://publications.waset.org/abstracts/search?q=Farzad%20Mirzaei%20Aminiyan"> Farzad Mirzaei Aminiyan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water quality is the critical factor that influence on human health and quantity and quality of grain production in semi-humid and semi-arid area. Pistachio is a main crop that accounts for a considerable portion of Iranian agricultural exports. Give that pistachio tree is a tolerant type of tree to saline and alkaline soil and water conditions, but groundwater and irrigation water quality play important roles in main production this crop. For this purpose, 94 well water samples were taken from 25 wells and samples were analyzed. The results showed give that region’s geological, climatic characteristics, statistical analysis, and based on dominant cations and anions in well water samples (piper diagram); four main types of water were found: Na-Cl, K-Cl, Na-SO4, and K-SO4. It seems that most wells in terms of water quality (salinity and alkalinity) and based on Wilcox diagram have critical status. The analysis suggested that more than eighty-seven percentage of the well water samples have high values of EC that these values are higher than into critical limit EC value for irrigation water, which may be due to the sandy soils in this area. Most groundwater were relatively unsuitable for irrigation but it could be used by application of correct management such as removing and reducing the ion concentrations of Cl‾, SO42‾, Na+ and total hardness in groundwater and also the concentrated deep groundwater was required treatment to reduce the salinity and sodium hazard. Given that irrigation water quality in this area was relatively unsuitable for most agriculture production but pistachio tree was adapted to this area conditions. The integrated management of groundwater for irrigation is the way to solve water quality issues not only in Rafsanjan area, but also in other arid and semi-arid areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=groundwater%20quality" title="groundwater quality">groundwater quality</a>, <a href="https://publications.waset.org/abstracts/search?q=irrigation%20water%20quality" title=" irrigation water quality"> irrigation water quality</a>, <a href="https://publications.waset.org/abstracts/search?q=salinity" title=" salinity"> salinity</a>, <a href="https://publications.waset.org/abstracts/search?q=alkalinity" title=" alkalinity"> alkalinity</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafsanjan%20plain" title=" Rafsanjan plain"> Rafsanjan plain</a>, <a href="https://publications.waset.org/abstracts/search?q=pistachio" title=" pistachio"> pistachio</a> </p> <a href="https://publications.waset.org/abstracts/10469/the-assessment-groundwater-geochemistry-of-some-wells-in-rafsanjan-plain-southeast-of-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10469.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">417</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">2</span> Energy-Efficient Storage of Methane Using Biosurfactant in the Form of Clathrate Hydrate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Farhadian">Abdolreza Farhadian</a>, <a href="https://publications.waset.org/abstracts/search?q=Anh%20Phan"> Anh Phan</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Taheri%20Rizi"> Zahra Taheri Rizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Elaheh%20Sadeh"> Elaheh Sadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The utilization of solidified gas technology based on hydrates exhibits considerable promise for carbon capture, storage, and natural gas transportation applications. The pivotal factor impeding the industrial implementation of hydrates lies in the need for efficient and non-foaming promoters. In this study, a biosurfactant with sulfonate, amide, and carboxyl groups (BS) was synthesized as a methane hydrate formation promoter, replicating the chemical characteristics of amino acids and sodium dodecyl sulfate (SDS). The synthesis of BS was achieved using an eco-friendly and three-step process. The first two steps were solvent-free, while a water-isopropanol mixture was utilized in the final step. High-pressure autoclave experiments demonstrated a significant enhancement in methane hydrate formation kinetics with low BS concentrations. 50 ppm of BS yielded a maximum water-to-hydrate conversion of 66.9%, equivalent to a storage capacity of 119.9 v/v in distilled water. With increasing BS concentration to 500 ppm, the conversion degree and storage capacity reached 97% and 162.6 v/v, respectively. Molecular dynamic simulation revealed that BS molecules acted as collectors for methane molecules, augmenting hydrate growth rate and increasing the number of hydrate cavities. Additionally, BS demonstrated a biodegradability exceeding 60% within 28 days. Toxicity assessments confirmed BS's biocompatibility, with cell viability above 70% for skin and lung cells at concentrations up to 160 and 80 µg/mL, respectively. BS showed significant potential as an environmentally friendly alternative to synthetic surfactants like SDS for methane storage. These findings suggest that the synthesis of effective, such as BS, holds promise for diverse applications, including seawater desalination, carbon capture, and gas storage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solidified%20methane" title="solidified methane">solidified methane</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20storage" title=" gas storage"> gas storage</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20hydrates" title=" gas hydrates"> gas hydrates</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20surfactant" title=" green surfactant"> green surfactant</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20hydrate%20promoter" title=" gas hydrate promoter"> gas hydrate promoter</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20simulation" title=" computational simulation"> computational simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/195035/energy-efficient-storage-of-methane-using-biosurfactant-in-the-form-of-clathrate-hydrate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/195035.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">0</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">1</span> Comparing the Efficacy of Minimally Supervised Home-Based and Closely Supervised Gym Based Exercise Programs on Weight Reduction and Insulin Resistance after Bariatric Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haleh%20Dadgostar">Haleh Dadgostar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Kaviani"> Sara Kaviani</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanieh%20Adib"> Hanieh Adib</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Mazaherinezhad"> Ali Mazaherinezhad</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Solaymani-Dodaran"> Masoud Solaymani-Dodaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Fahimeh%20Soheilipour"> Fahimeh Soheilipour</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Pazouki"> Abdolreza Pazouki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Objectives: Effectiveness of various exercise protocols in weight reduction after bariatric surgery has not been sufficiently explored in the literature. We compared the effect of minimally supervised home-based and closely supervised Gym based exercise programs on weight reduction and insulin resistance after bariatric surgery. Methods: Women undergoing gastric bypass surgery were invited to participate in an exercise program and were randomly allocated into two groups. They were either offered a minimally supervised home-based (MSHB) or closely supervised Gym-based (CSGB) exercise program. The CSGB protocol constitute two sessions per week of training under ACSM guidelines. In the MSHB protocol participants received a notebook containing a list of recommended aerobic and resistance exercises, a log to record their activity and a schedule of follow up phone calls and clinic visits. Both groups received a pedometer. We measured their weight, BMI, lipid profile, FBS, and insulin level at the baseline and after 20 weeks of exercise and were compared at the end of the study. Results: A total of 80 patients completed our study (MSHB=38 and CSGB=42). The baseline comparison showed that the two groups are similar. Using the ANCOVA method of analysis the mean change in BMI (covariate: BMI at the beginning of the study) was slightly better in CSGB compared with the MSHB (between-group mean difference: 3.33 (95%CI 4.718 to 1.943, F: 22.844 p < 0.001)). Conclusion: Our results showed that both MSHB and CSGB exercise methods are somewhat equally effective in improvement of studied factors in the two groups. With considerably lower costs of Minimally Supervised Home Based exercise programs, these methods should be considered when adequate funding are not available. <p
