Musculoskeletal pain is one of the most prevalent symptoms in elderly age. Nutrition and diet are considered important underlying factors that could affect chronic musculoskeletal pain. The purpose of this study was to identify the relationship between empirical dietary inflammatory patterns (EDII) and musculoskeletal pain. Method: In this cross-sectional study, 213 elderly individuals were selected from several health centers. The usual dietary intake was evaluated by a valid and reliable 147-items food frequency questionnaire (FFQ). To measure the intensity of pain, Visual Analogue Scale (VAS) was used. Multiple Linear Regression was applied to assess the association between EDII and musculoskeletal pain. Results: The results of multiple linear regression analysis indicate that a higher EDII score was associated with higher musculoskeletal pain (β= 0.21: 95% CI: 0.24-1.87: P= 0.003). These results stayed significant even after adjusting for covariates such as sex, marital status, height, family number, sleep, BMI, physical activity duration, waist circumference, protector, and medication use (β= 0.16: 95% CI: 0.11-1.04: P= 0.02). Conclusion: Study findings indicated that higher inflammation of diet might have a direct association with musculoskeletal pains in elderlies. However, further investigations are required to confirm these findings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=musculoskeletal%20pain" title="musculoskeletal pain">musculoskeletal pain</a>, <a href="https://publications.waset.org/abstracts/search?q=empirical%20dietary%20inflammatory%20pattern" title=" empirical dietary inflammatory pattern"> empirical dietary inflammatory pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=elderlies" title=" elderlies"> elderlies</a>, <a href="https://publications.waset.org/abstracts/search?q=dietary%20pattern" title=" dietary pattern"> dietary pattern</a> </p> <a href="https://publications.waset.org/abstracts/133109/the-association-of-empirical-dietary-inflammatory-index-with-musculoskeletal-pains-in-elderlies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133109.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">211</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">54</span> The Effect of Urmia-Lake Water on Tensional Strength Concrete with Various Admixtures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hadi%20Barghlame">Hadi Barghlame</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20A.%20Lotfollahi-Yaghin"> M.

These two types of media produced two different and sometimes conflicting narratives when faced with the news of a certain person's death, and the conflict is found between the narratives in some cases. This study has focused on the semiotics of these narratives, the interpretation of discourses supporting the narratives, and finally, their analysis within the framework of narrative theories. In the present study, the researcher has used a qualitative approach and has concluded that the narrative of both types of media is structured around the functions of the existing and ideal political system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=narrative" title="narrative">narrative</a>, <a href="https://publications.waset.org/abstracts/search?q=iran" title=" iran"> iran</a>, <a href="https://publications.waset.org/abstracts/search?q=fake%20news" title=" fake news"> fake news</a>, <a href="https://publications.waset.org/abstracts/search?q=protests" title=" protests"> protests</a>, <a href="https://publications.waset.org/abstracts/search?q=manipulation%20of%20reality" title=" manipulation of reality"> manipulation of reality</a> </p> <a href="https://publications.waset.org/abstracts/159190/narratives-and-meta-narratives-in-the-news-of-people-killed-in-2022-iranian-protests" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159190.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">98</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">51</span> Thermodynamic Analysis of an Ejector-Absorption Refrigeration Cycle with Using NH3-H2O</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samad%20Jafarmadar">Samad Jafarmadar</a>, <a href="https://publications.waset.org/abstracts/search?q=Amin%20Habibzadeh"> Amin Habibzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Mehdi%20Rashidi"> Mohammad Mehdi Rashidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sayed%20Sina%20Rezaei"> Sayed Sina Rezaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Abbas%20Aghagoli"> Abbas Aghagoli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the ejector-absorption refrigeration cycle is presented.

In this study, data mining techniques including Decision Trees, Artificial neural networks (ANNs), and Support Vector Machine (SVM) analyze CAD data. Data of 4948 patients who had suffered from heart diseases were included in the analysis. CAD is the target variable, and 24 inputs or predictor variables are used for the classification. The performance of these techniques is compared in terms of sensitivity, specificity, and accuracy. The most significant factor influencing CAD is chest pain. Elderly males (age > 53) have a high probability to be diagnosed with CAD. SVM algorithm is the most useful way for evaluation and prediction of CAD patients as compared to non-CAD ones. Application of data mining techniques in analyzing coronary artery diseases is a good method for investigating the existing relationships between variables. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=classification" title="classification">classification</a>, <a href="https://publications.waset.org/abstracts/search?q=coronary%20artery%20disease" title=" coronary artery disease"> coronary artery disease</a>, <a href="https://publications.waset.org/abstracts/search?q=data-mining" title=" data-mining"> data-mining</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20discovery" title=" knowledge discovery"> knowledge discovery</a>, <a href="https://publications.waset.org/abstracts/search?q=extract" title=" extract "> extract </a> </p> <a href="https://publications.waset.org/abstracts/1268/analysis-and-rule-extraction-of-coronary-artery-disease-data-using-data-mining" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1268.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">657</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">46</span> A Numerical and Experimental Study on Fast Pyrolysis of Single Wood Particle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Rezaei">Hamid Rezaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaotao%20Bi"> Xiaotao Bi</a>, <a href="https://publications.waset.org/abstracts/search?q=C.%20Jim%20Lim"> C.

The kinetic parameters were determined experimentally and the regime and characteristics of the conversion were evaluated in terms of the particle size and reactor temperature. The order of overall mass loss changed from n=1 at temperatures lower than 350 °C to n=0.5 at temperatures higher that 350 °C. Conversion time analysis showed that particles larger than 0.5 mm were controlled by internal thermal resistances. The valid range of particle size to use the simplified lumped model depends on the fluid temperature around the particles. The critical particle size was 0.6-0.7 mm for the fluid temperature of 500 °C and 0.9-1.0 mm for the fluid temperature of 100 °C. Experimental pyrolysis of moist particles did not show distinct drying and pyrolysis stages. The process was divided into two hypothetical drying and pyrolysis dominated zones and empirical correlations are developed to predict the rate of mass loss in each zone. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pyrolysis" title="pyrolysis">pyrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetics" title=" kinetics"> kinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=model" title=" model"> model</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20particle" title=" single particle"> single particle</a> </p> <a href="https://publications.waset.org/abstracts/57465/a-numerical-and-experimental-study-on-fast-pyrolysis-of-single-wood-particle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57465.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">320</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">45</span> Investigation of the Multiaxial Pedicle Screw Tulip Design Using Finite Element Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Daqiqeh%20Rezaei">S.

Multiaxial pedicle screws are a type of pedicle screw that increase surgical versatility, but they also increase design complexity. Failure of multiaxial pedicle screws caused by static loading, dynamic loading and fatigue can lead to irreparable damage to the patient. Inappropriate deformation of the multiaxial pedicle screw tulip can cause system failure. Investigation of deformation and stress in these tulips can be employed to optimize multiaxial pedicle screw design. The sensitivity of this matter necessitates precise analyzing and modeling of pedicle screws. In this work, three commercial multiaxial pedicle screw tulips and a newly designed tulip are investigated using finite element analysis. Employing video measuring machine (VMM), tulips are modeled. Afterwards, utilizing ANSYS, static analysis is performed on these models. In the end, stresses and displacements of the models are compared. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pedicle%20screw" title="pedicle screw">pedicle screw</a>, <a href="https://publications.waset.org/abstracts/search?q=multiaxial%20pedicle%20screw" title=" multiaxial pedicle screw"> multiaxial pedicle screw</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20analysis" title=" static analysis"> static analysis</a> </p> <a href="https://publications.waset.org/abstracts/29320/investigation-of-the-multiaxial-pedicle-screw-tulip-design-using-finite-element-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29320.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">368</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">44</span> Optimization of Floor Heating System in the Incompressible Turbulent Flow Using Constructal Theory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karim%20Farahmandfar">Karim Farahmandfar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidolah%20Izadi"> Hamidolah Izadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Rezaei"> Mohammadreza Rezaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Amin%20Ardali"> Amin Ardali</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebrahim%20Goshtasbi%20Rad"> Ebrahim Goshtasbi Rad</a>, <a href="https://publications.waset.org/abstracts/search?q=Khosro%20Jafarpoor"> Khosro Jafarpoor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Statistics illustrates that the higher amount of annual energy consumption is related to surmounting the demand in buildings. Therefore, it is vital to economize the energy consumption and also find the solution with regard to this issue. One of the systems for the sake of heating the building is floor heating. As a matter of fact, floor heating performance is based on convection and radiation. Actually, in addition to creating a favorable heating condition, this method leads to energy saving. It is the goal of this article to outline the constructal theory and introduce the optimization method in branch networks for floor heating. There are several steps in order to gain this purpose. First of all, the pressure drop through the two points of the network is calculated. This pressure drop is as a function of pipes diameter and other parameters. After that, the amount of heat transfer is determined. Consequently, as a result of the combination of these two functions, the final function will be determined. It is necessary to mention that flow is laminar. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constructal%20theory" title="constructal theory">constructal theory</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=floor%20heating%20system" title=" floor heating system"> floor heating system</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulent%20flow" title=" turbulent flow"> turbulent flow</a> </p> <a href="https://publications.waset.org/abstracts/54375/optimization-of-floor-heating-system-in-the-incompressible-turbulent-flow-using-constructal-theory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54375.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">319</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">43</span> Evidence Based Medicine: Going beyond Improving Physicians Viewpoints, Usage and Challenges Upcoming</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peyman%20Rezaei%20Hachesu">Peyman Rezaei Hachesu</a>, <a href="https://publications.waset.org/abstracts/search?q=Vahideh%20Zareh%20Gavgani"> Vahideh Zareh Gavgani</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Salahzadeh"> Zahra Salahzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To survey the attitudes, awareness, and practice of Evidence Based Medicine (EBM), and to determine the barriers that influence apply’ EBM in therapeutic process among clinical residents in Iran.We conducted a cross sectional survey during September to December 2012 at the teaching hospitals of Tehran University of Medical Sciences among 79 clinical residents from different medical specialties. A valid and reliable questionnaire consisted of five sections and 27 statements were used in this research. We applied Spearman and Mann Whitney test for correlation between variables. Findings showed that the knowledge of residents about EBM is low. Their attitude towards EBM was positive but their knowledge and skills in regard with the evidence based medical information resources were mostly limited to PubMed and Google scholar. The main barrier was the lack of enough time to practicing EBM. There was no significant correlation between residency grade and familiarity and use of electronic EBM resources (Spearman, P = 0.138). Integration of training approaches like journal clubs or workshops with clinical practice is suggested. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=evidence-based%20medicine" title="evidence-based medicine">evidence-based medicine</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20residents" title=" clinical residents"> clinical residents</a>, <a href="https://publications.waset.org/abstracts/search?q=decision-making" title=" decision-making"> decision-making</a>, <a href="https://publications.waset.org/abstracts/search?q=attitude" title=" attitude"> attitude</a>, <a href="https://publications.waset.org/abstracts/search?q=questionnaire" title=" questionnaire"> questionnaire</a> </p> <a href="https://publications.waset.org/abstracts/1809/evidence-based-medicine-going-beyond-improving-physicians-viewpoints-usage-and-challenges-upcoming" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1809.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">376</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">42</span> Exploring the Effect of Accounting Information on Systematic Risk: An Empirical Evidence of Tehran Stock Exchange</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Rezaei">Mojtaba Rezaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Heydari"> Elham Heydari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper highlights the empirical results of analyzing the correlation between accounting information and systematic risk.

Financial ratios have been categorized into four groups and to describe the special features, as representative of accounting information we selected: Return on Asset (ROA), Debt Ratio (Total Debt to Total Asset), Current Ratio (current assets to current debt), Asset Turnover (Net sales to Total assets), and Total Assets. The hypotheses were tested through simple and multiple linear regression and T-student test. The findings illustrate that there is no significant relationship between accounting information and market risk.

As changes in performance can have many negative impacts on society, it is essential to be able to evaluate and measure the performance of bridges throughout their life. This evaluation includes the development or the choice of the appropriate performance indicators, which, in turn, are measured based on the selection of appropriate models for the existing deterioration mechanism. The purpose of this article is a statistical study of indicators and deterioration mechanisms of bridges in order to discover further research capacities in bridges performance assessment. For this purpose, some of the most common indicators of bridge performance, including reliability, risk, vulnerability, robustness, and resilience, were selected. The researches performed on each index based on the desired deterioration mechanisms and hazards were comprehensively reviewed. In addition, the formulation of the indicators and their relationship with each other were studied. The research conducted on the mentioned indicators were classified from the point of view of deterministic or probabilistic method, the level of study (element level, object level, etc.), and the type of hazard and the deterioration mechanism of interest. For each of the indicators, a number of challenges and recommendations were presented according to the review of previous studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bridge" title="bridge">bridge</a>, <a href="https://publications.waset.org/abstracts/search?q=deterioration%20mechanism" title=" deterioration mechanism"> deterioration mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=lifecycle" title=" lifecycle"> lifecycle</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20indicator" title=" performance indicator"> performance indicator</a> </p> <a href="https://publications.waset.org/abstracts/125555/review-and-classification-of-the-indicators-and-trends-used-in-bridge-performance-modeling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125555.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">105</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">40</span> Effects of Allium Sativum Essential Oil on MIC, MBC and Growth Curve of Vibrio Parahaemolyticus ATCC 43996 and Its Thermostable Direct Hemolysin Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Afshin%20Akhondzadeh%20Basti">Afshin Akhondzadeh Basti</a>, <a href="https://publications.waset.org/abstracts/search?q=Zohreh%20Mashak"> Zohreh Mashak</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Khanjari"> Ali Khanjari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Adel%20Rezaei"> Mohammad Adel Rezaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatemeh%20Mohammadkhan"> Fatemeh Mohammadkhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Vibrio parahaemolyticus is a halophilic bacterium and often causes gastroenteritis because of consumption of raw or inadequately cooked seafood.

MIC and MBC of Allium sativum essential oil was estimated 0.03%. The results of this study revealed that the TDH production was significantly affected by Allium sativum EO and titers of TDH production in 0 and 0.005 % were 1/256 whereas this titer in 0.015 % concentration of EO. Concentrations of 0.005 and 0/015 % of garlic essential oil reduced the bacterial growth rate significantly (P < 0.05) compared to the control group.

Since waste management is a major priority and has profound impacts on the volume of waste generated in construction stage, the majority of efforts have been attempted to reuse, recycle and reduce waste. However, there is still room to study on lack of sufficient knowledge about waste management in construction industry. This paper intends to provide an insight into the effect of project management knowledge areas on waste management solely on construction stage. To this end, a survey among Iranian building construction industry contractors was conducted to identify the effectiveness of project management knowledge areas on three jobsite key factors including ‘Site activity’, ‘Training’, and ‘Awareness’. As a result, four management disciplines were identified as most influential ones on amount of construction waste. These disciplines were Project Cost Management, Quality Management, Human Resource Management, and Integration Management.

Since the term 'construction waste' covers a vast spectrum of materials in constructing buildings, roads and etc., many investigations are required to measure their technical performance in use as well as their time and place of use. Concrete is among the major and fundamental materials used in current construction industry. Along with the rise of population in developing countries, it is desperately required to meet the people's primary need in construction industry and on the other hand, dispose existing wastes for reducing the amount of environmental pollutants. Restrictions of natural resources and environmental pollution are the most important problems encountered by civil engineers. Reusing construction waste is an important and economic approach that not only assists the preservation of environment but also, provides us with primary raw materials. In line with consistent municipal development in disposal and reuse of construction waste, several approaches including, management of construction waste and materials, materials recycling and innovation and new inventions in materials have been predicted. This article has accordingly attempted to study the activities related to recycling of construction wastes and then, stated the economic, quantitative, qualitative and environmental results obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=civil%20engineering" title="civil engineering">civil engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling" title=" recycling"> recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20waste" title=" construction waste "> construction waste </a> </p> <a href="https://publications.waset.org/abstracts/32501/recycling-construction-waste-materials-to-reduce-the-environmental-pollutants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32501.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">305</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">36</span> User-Friendly Task Creation Using a CAD Integrated Robotic System on a Real Workcell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Changizi">Alireza Changizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Arash%20Rezaei"> Arash Rezaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamal%20Muhammad"> Jamal Muhammad</a>, <a href="https://publications.waset.org/abstracts/search?q=Jyrki%20Latokartano"> Jyrki Latokartano</a>, <a href="https://publications.waset.org/abstracts/search?q=Minna%20Lanz"> Minna Lanz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Offline programming (OLP) is a new method in robot programming which is used widely in the industry nowadays which is a simulation base method that can produce the robot codes for motion according to virtual world in the simulation software. In this project Delmia v5 is used as simulation software. First the work cell component was modelled by Catia v5 and all of them was imported to a process file in Delmia and placed roughly to form the virtual work cell. Then robot was added to the work cell from the Delmia library. Work cell was calibrated corresponding to real world work cell to have accurate code. Tool calibration is the first step of calibration scheme and then work cell equipment can be calibrated using 6 point calibration method. Finally generated code needs to be reformed to match related controller code instruction. At the last stage IO were set to accomplish robots cooperation and make their motion synchronized. The pros and cons also will be discussed to clarify the presented results show the feasibility of the method and its effect on production line efficiency. Finally the positive and negative points of the implementation will be discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=robotic" title="robotic">robotic</a>, <a href="https://publications.waset.org/abstracts/search?q=automated" title=" automated"> automated</a>, <a href="https://publications.waset.org/abstracts/search?q=production" title=" production"> production</a>, <a href="https://publications.waset.org/abstracts/search?q=offline%20programming" title=" offline programming"> offline programming</a>, <a href="https://publications.waset.org/abstracts/search?q=CAD" title=" CAD"> CAD</a> </p> <a href="https://publications.waset.org/abstracts/20896/user-friendly-task-creation-using-a-cad-integrated-robotic-system-on-a-real-workcell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20896.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">387</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">35</span> Agricultural Biotechnology Crop Improvement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Rezaei%20Aghdam">Mohsen Rezaei Aghdam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recombinant DNA technology has meaningfully augmented the conventional crop improvement and has a great possibility to contribution plant breeders to encounter the augmented food request foretold for the 21st century.

Torsion of the spermatic cord is an emergency condition resulting from the rotation of the testis and epididymis around the axis of the spermatic cord. A rat testis model was used to assess the effects of β-cryptoxanthin on ischemia-reperfusion injury. Twenty healthy male Wistar rats were included and randomized into four investigational groups (n = 5): Group SHAM: In this group, midline incision of the scrotum was performed, and the testicles were taken out for 2 hours with a 720-degree rotation. Group ISCHEMIA: In this group, a midline incision of the scrotum was performed, and the testicles were taken out and underwent ischemia for 2 hours with a 720-degree rotation. Group IS/REP/Oil: In this group, a midline scrotum cut was performed the testicles were taken out, and ischemia was created for 2 hours with a 720-degree rotation and at the end of ischemia 100 µL of corn oil (β-cryptoxanthin solvent) was injected intraperitoneally. Group IS/REP/CRPTXNTN 2.5: The same as group IS/REP/Oil as well as intraperitoneal administration of 100 µL of β-cryptoxanthin (2.5 µg/kg) at the end of ischemia. In all groups, the testes were returned back to the scrotum and, after 60 days, were dissected out and removed for histopathological analyses. β-cryptoxanthin at the dose of 2.5 µg/kg significantly improved histologic indices compared to other treatment groups (p<0.05). β-cryptoxanthin could be helpful in minimizing ischemia-reperfusion injury in testicular tissue exposed to ischemia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beta-cryptoxanthin" title="beta-cryptoxanthin">beta-cryptoxanthin</a>, <a href="https://publications.waset.org/abstracts/search?q=testis" title=" testis"> testis</a>, <a href="https://publications.waset.org/abstracts/search?q=Ischemia-reperfusion" title=" Ischemia-reperfusion"> Ischemia-reperfusion</a>, <a href="https://publications.waset.org/abstracts/search?q=Intraperitoneal" title=" Intraperitoneal"> Intraperitoneal</a> </p> <a href="https://publications.waset.org/abstracts/189306/the-effect-of-v-cryptoxanthin-on-testicular-ischemia-reperfusion-injury-in-a-rat-model-evidence-from-testicular-histology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189306.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">18</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">33</span> Survey on Prevalence of Endo and Ecto-Parasites of Rattus rattus in Mazandaran Province, North of Iran </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatemeh%20Rezaei">Fatemeh Rezaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Afsaneh%20Amouei"> Afsaneh Amouei</a>, <a href="https://publications.waset.org/abstracts/search?q=Iman%20Bakouei"> Iman Bakouei</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Sharif"> Mahdi Sharif</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahabeddin%20Sarvi"> Shahabeddin Sarvi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Taghi%20Rahimi"> Mohammad Taghi Rahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Daryani"> Ahmad Daryani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Rodents act as reservoir host and important potential source for many zoonotic pathogens which pose a public health risk to humans. Therefore, it is necessary to investigate the prevalence of gastrointestinal and ectoparasites among rodents. Materials and Methods: 118 Rattus rattus were captured using snap live traps. Each rat was combed with a fine tooth comb to dislodge ectoparasite and studied. Various samples were collected from feces, examined wet smear, formalin-ether method and stained with modified acid-fast staining and trichrome. Result: The overall prevalence of gastrointestinal parasites of examined rats was 75.4%. Cryptosporidium 30.5%, was the most prevalent protozoan which was followed by Giardia 20.3% and Entamoeba muris 13.5%, Trichomonas muris 10.1% and Spironucleus muris 3.3%. The prevalence of helminth egg was as following Syphacia obvelata 24.5%, Hymenolepis diminuta 10.1% and Trichuris muris 9.3%. 86.4% rodents were found to be infested with ectoparasites including mite 35.6%, flea 28.4%, and lice 42.7%. A significant statistical difference was observed between prevalence and gender of infected individuals. Conclusions: The prevalence of gastrointestinal and ectoparasites of collected rats in studied area is remarkably high. In addition, Rattus rattus can be considered as potential risk for human health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=prevalence" title="prevalence">prevalence</a>, <a href="https://publications.waset.org/abstracts/search?q=rodent" title=" rodent"> rodent</a>, <a href="https://publications.waset.org/abstracts/search?q=intestinal%20parasites" title=" intestinal parasites"> intestinal parasites</a>, <a href="https://publications.waset.org/abstracts/search?q=ecto-parasites" title=" ecto-parasites"> ecto-parasites</a>, <a href="https://publications.waset.org/abstracts/search?q=zoonose" title=" zoonose"> zoonose</a> </p> <a href="https://publications.waset.org/abstracts/55033/survey-on-prevalence-of-endo-and-ecto-parasites-of-rattus-rattus-in-mazandaran-province-north-of-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55033.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">532</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">32</span> The Effects of the War between Russia and Ukraine on Qatar’s Fossil and Renewable Energy Policies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rahmat%20Hajimineh">Rahmat Hajimineh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebrahim%20Rezaei%20Rad"> Ebrahim Rezaei Rad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The war between Russia and Ukraine is considered a very important event in international relations, especially after the end of the Cold War, a war that has had wide dimensions since its beginning. Dimensions that, in addition to political issues, have especially affected the world economy and especially the two countries. The most important issue in the field of the economy that was affected by the war between Russia and Ukraine was the issue of energy. Russia is one of the largest producers and suppliers of natural gas for European countries, and 40% of European gas is supplied by Russia. For this reason, it is natural that European countries have problems in this regard. On the other hand, Ukraine is considered the gateway to Europe for Russia regarding the export of natural gas. The war in Ukraine has had severe effects on gas and energy in Europe. From this point of view, European countries are looking to diversify their energy path by switching to renewable energies, and they are also looking at other energy-producing countries like Qatar to meet their energy needs. In this article, we are trying to investigate the impact of the war between Russia and Ukraine on Qatar's policies in the field of fossil and renewable energy. The descriptive-analytical method and the theoretical framework of energy security have been used to review this article. Based on this, the article examines the situation of fossil and renewable energies in Qatar and, on the other hand, the effects of the war in Ukraine on both energies in Qatar. The findings of this article also indicate that Qatar has made changes in its energy policies after the war in Ukraine, which seems to be possible due to its high potential, especially in the field of renewable and fossil energy. There is an export of surplus production of this country to other countries, especially European countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ukraine%20War" title="Ukraine War">Ukraine War</a>, <a href="https://publications.waset.org/abstracts/search?q=fossil%20fuels" title=" fossil fuels"> fossil fuels</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20security" title=" energy security"> energy security</a>, <a href="https://publications.waset.org/abstracts/search?q=Qatar" title=" Qatar"> Qatar</a> </p> <a href="https://publications.waset.org/abstracts/155801/the-effects-of-the-war-between-russia-and-ukraine-on-qatars-fossil-and-renewable-energy-policies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155801.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">31</span> Predicting the Quality of Life on the Basis of Perceived Social Support among Patients with Coronary Artery Bypass Graft</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azadeh%20Yaraghchi">Azadeh Yaraghchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Bagherian%20Sararoodi"> Reza Bagherian Sararoodi</a>, <a href="https://publications.waset.org/abstracts/search?q=Niknaz%20Salehi%20Moghadam"> Niknaz Salehi Moghadam</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Hossein%20Mandegar"> Mohammad Hossein Mandegar</a>, <a href="https://publications.waset.org/abstracts/search?q=Adis%20Kraskian%20Mujembari"> Adis Kraskian Mujembari</a>, <a href="https://publications.waset.org/abstracts/search?q=Omid%20Rezaei"> Omid Rezaei </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Quality of life is one of the most important consequences of disease in psychosomatic disorders. Many psychological factors are considered in predicting quality of life in patients with coronary artery bypass graft (CABG). The present study was aimed to determine the relationship between perceived social support and quality of life in patients with coronary artery bypass graft (CABG). Methods: The population included 82 patients who had undergone CABG from October 2014 to May 2015 in four different hospitals in Tehran. The patients were evaluated with Multi-dimension scale of perceived social support (MSPSS) and after three months follow up were evaluated by Short-Form quality of life questionnaire (SF-36). The obtained data were analyzed through Pearson correlation test and multiple variable regression models. Findings: A relationship between perceived social support and quality of life in patients with CABG was observed (r=0.374, p<0.01). The results showed that 22.4% of variation in quality of life is predicted by perceived social support components (p<0.01, R2 =0.224). Conclusion: Based on the results, perceived social support is one of the predictors of quality of life in patients with coronary artery bypass graft. Accordingly, these results can be useful in conceiving proactive policies, detecting high risk patients and planning for psychological interventions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coronary%20artery%20bypass%20graft" title="coronary artery bypass graft">coronary artery bypass graft</a>, <a href="https://publications.waset.org/abstracts/search?q=perceived%20social%20support" title=" perceived social support"> perceived social support</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20factors" title=" psychological factors"> psychological factors</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a> </p> <a href="https://publications.waset.org/abstracts/77298/predicting-the-quality-of-life-on-the-basis-of-perceived-social-support-among-patients-with-coronary-artery-bypass-graft" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77298.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">369</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">30</span> Biogas as a Renewable Energy Fuel: A Review of Biogas Upgrading, Utilization and Storage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imran%20Ullah%20Khana">Imran Ullah Khana</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Hafiz%20Dzarfan%20Othmanb"> Mohd Hafiz Dzarfan Othmanb</a>, <a href="https://publications.waset.org/abstracts/search?q=Haslenda%20Hashima"> Haslenda Hashima</a>, <a href="https://publications.waset.org/abstracts/search?q=Takeshi%20Matsuurad"> Takeshi Matsuurad</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20F.%20Ismailb"> A.

The production of biomethane provides a versatile application in both heat and power generation and as a vehicular fuel. This paper systematically reviews the state of the art of biogas upgrading technologies with upgrading efficiency, methane (CH4) loss, environmental effect, development and commercialization, and challenges in terms of energy consumption and economic assessment. The market situation for biogas upgrading has changed rapidly in recent years, giving membrane separation a significant market share with traditional biogas upgrading technologies. In addition, the potential utilization of biogas, efficient conversion into bio-compressed natural gas (bio-CNG), and storage systems are investigated in depth. Two storing systems for bio-CNG at filling stations, namely buffer and cascade storage systems are used. The best storage system should be selected on the basis of the advantages of both systems. Also, the fuel economy and mass emissions for bio-CNG and CNG-filled vehicles are studied. There is the same fuel economy and less carbon dioxide (CO2) emission for bio-CNG. Based on the results of comparisons between the technical features of upgrading technologies, various specific requirements for biogas utilization and the relevant investment, and operating and maintenance costs, future recommendations are made for biogas upgrading. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biogas%20upgrading" title="biogas upgrading">biogas upgrading</a>, <a href="https://publications.waset.org/abstracts/search?q=cost" title=" cost"> cost</a>, <a href="https://publications.waset.org/abstracts/search?q=utilization" title=" utilization"> utilization</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-CNG" title=" bio-CNG"> bio-CNG</a>, <a href="https://publications.waset.org/abstracts/search?q=storage" title=" storage"> storage</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a> </p> <a href="https://publications.waset.org/abstracts/184961/biogas-as-a-renewable-energy-fuel-a-review-of-biogas-upgrading-utilization-and-storage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184961.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">50</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">29</span> Large Eddy Simulation Approach for Unsteady Analysis of the Flow Behavior inside a Dual Counter Rotating Axial Swirler</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Foad%20Vashahi">Foad Vashahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahnaz%20Rezaei"> Shahnaz Rezaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeekeun%20Lee"> Jeekeun Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Large Eddy Simulation (LES) was performed on a dual counter rotating axial swirler in a confined rectangular configuration. Grids were constructed based on a primary Reynolds Averaged Navier-Stokes (RANS) simulation and then were refined based on the Kolmogorov length scale. Water as cold flow condition was applied and results were compared via Particle Image Velocimetry (PIV) experimental results. The focus was to investigate the flow behavior within the region before the flare and very close to the exit of the swirler. This region contributes to a highly unsteady flow behavior and requires great attention to enhancing the flame stability in gas turbine combustor and swirl burners. The PVC formation within the central core flow is strongly related to the peaks of pressure or axial velocity spectrum and up to two distinct peaks at the swirler mouth could be observed. Here, spectra analysis in iso-thermal condition inside the swirler where the inner swirler dominates the flow, showed a higher potential of instabilities with three to four distinct peaks where moving forward to the exit of swirler the number of peaks is decreased. In addition to this, the central axis corresponds to no peaks of instabilities while further away in the radial direction, several peaks exist. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axial%20counter%20rotating%20swirler" title="axial counter rotating swirler">axial counter rotating swirler</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20eddy%20simulation%20%28LES%29" title=" large eddy simulation (LES)"> large eddy simulation (LES)</a>, <a href="https://publications.waset.org/abstracts/search?q=precessing%20vortex%20core%20%28PVC%29" title=" precessing vortex core (PVC)"> precessing vortex core (PVC)</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20spectral%20density%20%28PSD%29" title=" power spectral density (PSD)"> power spectral density (PSD)</a> </p> <a href="https://publications.waset.org/abstracts/68069/large-eddy-simulation-approach-for-unsteady-analysis-of-the-flow-behavior-inside-a-dual-counter-rotating-axial-swirler" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68069.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">280</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">28</span> The Effect of Compound Exercises Emphasizing Local and Global Stability on the Dynamic Balance in Elite Taekwondo Athletes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elnaz%20Sabzehparvar">Elnaz Sabzehparvar</a>, <a href="https://publications.waset.org/abstracts/search?q=Pouya%20Rabiei"> Pouya Rabiei</a>, <a href="https://publications.waset.org/abstracts/search?q=Houman%20Rezaei"> Houman Rezaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Few studies have been conducted about the effects of compound exercises emphasizing local stability and global stabilization subsystems on the performance of athletes. The present research aimed to study the effect of 6 weeks of compound exercises emphasizing local and global stability on the dynamic balance of elite male Taekwondo athletes. Twenty-seven elite male Taekwondo athletes (with a mean age, mass, and height of 24.4 ± 4.9 years, 75.7 ± 15.1kg, and 181.4 ± 7.8 cm, respectively) were assigned to two groups of control (n=12) and exercise (n=15). 6 weeks of compound exercises in 2 local and global phases. The first phase included activation exercises which were done separately and locally for 3 weeks. Then, integrative exercises specific to the global stabilization subsystems (longitudinal-depth, posterior oblique and anterior, and lateral) was carried out for next 3 weeks. The dynamic balance of subjects was measured in the pre-test and post-test using the Y Balance Test (YBT). After 6 weeks of compound exercises, scores of the YBT in the exercise group showed a significant improvement in all three anterior (p=0.035), posterolateral (p=0.017) and medial (p=0.001) directions in the post-test compared to the control group (p ≤ 0.05 for all comparisons). The findings of the present study suggested that compound exercises focusing on muscle as separate units and then as interdependent chains (muscular subsystems) can significantly increase YBT on elite male Taekwondo athletes in all three directions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taekwondo" title="Taekwondo">Taekwondo</a>, <a href="https://publications.waset.org/abstracts/search?q=compound%20exercises" title=" compound exercises"> compound exercises</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20and%20global%20stability" title=" local and global stability"> local and global stability</a>, <a href="https://publications.waset.org/abstracts/search?q=muscular%20subsystems" title=" muscular subsystems"> muscular subsystems</a> </p> <a href="https://publications.waset.org/abstracts/76525/the-effect-of-compound-exercises-emphasizing-local-and-global-stability-on-the-dynamic-balance-in-elite-taekwondo-athletes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76525.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">224</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">27</span> Sub-Lethal Effects of Thiamethoxam and Pirimicarb on Life-Table Parameters of Diaeretiella rapae (Hymenoptera: Braconidae), Parasitoid of Lipaphis erysimi (Hemiptera: Aphididae)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nastaran%20Rezaei">Nastaran Rezaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Saeed%20Mossadegh"> Mohammad Saeed Mossadegh</a>, <a href="https://publications.waset.org/abstracts/search?q=Farhan%20Kocheyli"> Farhan Kocheyli</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalil%20Talebi%20Jahromi"> Khalil Talebi Jahromi</a>, <a href="https://publications.waset.org/abstracts/search?q=Aurang%20Kavousi"> Aurang Kavousi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Integrated Pest Management (IPM) aims to combine biological and chemical strategies and measures, hence highlighting the study of acute toxicity and sub-lethal effects of pesticides comprehensively. The present research focused on the side effects of thiamethoxam and pirimicarb sub-lethal concentrations on demographic parameters of <em>Diaeretiella</em> <em>rapae</em> (McIntosh Laboratory) (Hymenoptera: Braconidae). Adult parasitoids were exposed to LC<sub>25</sub> of insecticides as well as distilled water as the control. The results showed that thiamethoxam adversely affected population parameters (<em>r, λ, R<sub>0</sub>, T</em>), adults' longevity, females' oviposition period and mean fecundity, and a similar trend was obtained for pirimicarb with the exception of generation time (<em>T</em>), the latter did not significantly change compared to the control. The intrinsic rate of increase (<em>r</em>) in the control and those treated with pirimicarb and thiamethoxam were 0.2801, 0.2064, 0.1525 days<sup>-1</sup>, respectively, and the sex ratio was biased toward females in all treatments. Furthermore, none of the insecticides influenced total pre-oviposition period (TPOP) and offspring emergence rate. In general, these results indicated that both insecticides potentially distort the demographic parameters of the parasitoid even at sub-lethal concentrations, and then they should not be considered for IPM program in the presence of <em>D. rapae</em>. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diaeretiella%20rapae" title="Diaeretiella rapae">Diaeretiella rapae</a>, <a href="https://publications.waset.org/abstracts/search?q=Lipaphis%20erysimi" title=" Lipaphis erysimi"> Lipaphis erysimi</a>, <a href="https://publications.waset.org/abstracts/search?q=life-table%20study" title=" life-table study"> life-table study</a>, <a href="https://publications.waset.org/abstracts/search?q=pirimicarb" title=" pirimicarb"> pirimicarb</a>, <a href="https://publications.waset.org/abstracts/search?q=thiamethoxam" title=" thiamethoxam"> thiamethoxam</a> </p> <a href="https://publications.waset.org/abstracts/89685/sub-lethal-effects-of-thiamethoxam-and-pirimicarb-on-life-table-parameters-of-diaeretiella-rapae-hymenoptera-braconidae-parasitoid-of-lipaphis-erysimi-hemiptera-aphididae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89685.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">192</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">26</span> Petrology Investigation of Apatite Minerals in the Esfordi Mine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haleh%20Rezaei%20Zanjirabadi">Haleh Rezaei Zanjirabadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatemeh%20Saberi"> Fatemeh Saberi</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahman%20Rahimzadeh"> Bahman Rahimzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Fariborz%20Masoudi"> Fariborz Masoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Rahgosha"> Mohammad Rahgosha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, apatite minerals from the iron-phosphate deposit of Yazd have been investigated within the microcontinent zone of Iran in the Zagros structural zone. The geological units in the Esfordi area belong to the pre-Cambrian to lower-Cambrian age, consisting of a succession of carbonate rocks (dolomite), shale, tuff, sandstone, and volcanic rocks. In addition to the mentioned sedimentary and volcanic rocks, the granitoid mass of Bahabad, which is the largest intrusive mass in the region, has intruded into the eastern part of this series and has caused its metamorphism and alteration. After collecting the available data, various samples of Esfordi’s apatite were prepared, and their mineralogy and crystallography were investigated using laboratory methods such as petrographic microscopy, Raman spectroscopy, EDS, and SEM. In non-destructive Raman spectroscopy, the molecular structure of apatite minerals was revealed in four distinct spectral ranges. Initially, the spectra of phosphate and aluminum bonds with O2HO, OH, were observed, followed by the identification of Cl, OH, Al, Na, Ca and hydroxyl units depending on the type of apatite mineral family. In SEM analysis, based on various shapes and different phases of apatites, their constituent major elements were identified through EDS, indicating that the samples from the Esfordi mining area exhibit a dense and coherent texture with smooth surfaces. Based on the elemental analysis results by EDS, the apatites in the Esfordi area are classified into the calcic apatite group. <p class="card-text"><strong>Keywords:</strong> <a
