The responsibility acquired a big importance in front of this financial crisis. This responsibility requires more transparency and communication, inside the company with the collaborators and outside of the company with the society, while companies try to improve the degree of control and to authorize managers to realize the objectives of the company. The objective of this paper is to present the concept of the responsibility generally and the various types of manager’s responsibility in private individual within the company, as well as the explanatory theories of this responsibility through the various perspectives such as: economic, political, social and behavioral. This study should have academic and practical contributions particularly for regulators seeking to improve the companies’ practices and organizational functioning within capital market economy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=manager" title="manager">manager</a>, <a href="https://publications.waset.org/abstracts/search?q=accountability" title=" accountability"> accountability</a>, <a href="https://publications.waset.org/abstracts/search?q=corporate%20performance" title=" corporate performance"> corporate performance</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20crisis" title=" financial crisis"> financial crisis</a>, <a href="https://publications.waset.org/abstracts/search?q=behavior" title=" behavior"> behavior</a> </p> <a href="https://publications.waset.org/abstracts/17677/responsibility-of-corporate-manager-to-synthesize-of-the-different-theories-by-economic-political-social-and-behavioral-perspectives" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17677.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">393</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> Carbon Nanocomposites : Structure, Characterization and Environmental Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bensacia%20Nabila">Bensacia Nabila</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadj-Ziane%20Amel"> Hadj-Ziane Amel</a>, <a href="https://publications.waset.org/abstracts/search?q=Sefah%20Karima"> Sefah Karima</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carbon nanocomposites have received more attention in the last years in view of their special properties such as low density, high specific surface area, and thermal and mechanical stability. Taking into account the importance of these materials, many studies aimed at improving the synthesis process have been conducted. However, the presence of impurities could affect significantly the properties of these materials, and the characterization of these compounds is an important challenge to assure the quality of the new carbon nanocomposites. The present study aims to develop a new recyclable decontaminating material for dyes removal. This new material consists of an active element based on carbon nanotubes wrapped in a microcapsule of iron oxide. The adsorbent is characterized by Transmission electron microscopy, X-ray diffraction and the surface area was measured by the BET method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanocomposite" title="carbon nanocomposite">carbon nanocomposite</a>, <a href="https://publications.waset.org/abstracts/search?q=chitozen" title=" chitozen"> chitozen</a>, <a href="https://publications.waset.org/abstracts/search?q=elimination" title=" elimination"> elimination</a>, <a href="https://publications.waset.org/abstracts/search?q=dyes" title=" dyes"> dyes</a> </p> <a href="https://publications.waset.org/abstracts/37844/carbon-nanocomposites-structure-characterization-and-environmental-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37844.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">321</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">39</span> E-Learning Approaches Based on Artificial Intelligence Techniques: A Survey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabila%20Daly">Nabila Daly</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamdi%20Ellouzi"> Hamdi Ellouzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hela%20Ltifi"> Hela Ltifi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In last year’s, several recent researches’ that focus on e-learning approaches having as goal to improve pedagogy and student’s academy level assessment.

Several damages were caused by the infiltration of water in the soils, in particular in clay regions which can swell under the effect of an increase in their water content as in the case of the Oued Tlelat clay which is made up of yellow-colored marly clays and red-colored El Maleh area. This study was carried out on soil from a site, located near the city of Oran and the city of Ain Tmouchent (northern Algeria) where we encounter many problems of cracking of buildings and bottom uplift of excavations. The study consists first of all in determining the mechanical and physical characteristics of the clay, namely the parameters of sheer, simple compression, and that of the odometer. Then the study focused on a comparison of the influence of water type on the mechanical and physical properties of swelling clay soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clay" title="clay">clay</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a>, <a href="https://publications.waset.org/abstracts/search?q=liquidity%20limit" title=" liquidity limit"> liquidity limit</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20limit" title=" plastic limit"> plastic limit</a> </p> <a href="https://publications.waset.org/abstracts/150577/clay-develop-plasticity-with-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150577.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">101</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">37</span> Performance Study of PV Power plants in Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Razika%20Ihaddadene">Razika Ihaddadene</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabila%20Ihaddadene"> Nabila Ihaddadene</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to highlight the importance of the application of the IEC 61724 standard in the study of the performance analysis of photovoltaic power plants on a monthly and annual scale. Likewise, the comparison of two photovoltaic power plants with two different climates was carried out in order to determine the effect of climatic parameters on the analysis of photovoltaic performances. All data from the Ain Skhouna and Adrar photovoltaic power plants for 2018 and the data from the Saida1 field for one month in 2019 were used. The results of the performance analysis according to the indicated standard show that the Saida PV power plant performs better than the Adrar PV power plant, which is due to the effect of increasing the ambient temperature. Increasing ambient temperature increases losses decreases system efficiency and performance ratio. It presents a key element in the proper functioning of PV plants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pv%20power%20plants" title="pv power plants">pv power plants</a>, <a href="https://publications.waset.org/abstracts/search?q=IEC%2061724%20norm" title=" IEC 61724 norm"> IEC 61724 norm</a>, <a href="https://publications.waset.org/abstracts/search?q=grid%20connected%20pv" title=" grid connected pv"> grid connected pv</a>, <a href="https://publications.waset.org/abstracts/search?q=algeria" title=" algeria"> algeria</a> </p> <a href="https://publications.waset.org/abstracts/173398/performance-study-of-pv-power-plants-in-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173398.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">77</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Validity Study of The Zimbardo’s Stanford Time Perspective Inventory in Indonesia Students Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anggi%20Permana">Anggi Permana</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahrah%20Nabila%20Putri"> Zahrah Nabila Putri</a>, <a href="https://publications.waset.org/abstracts/search?q=Anisa%20Dwi%20Arifani"> Anisa Dwi Arifani</a>, <a href="https://publications.waset.org/abstracts/search?q=Veany%20Aprillia"> Veany Aprillia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research aims to evaluate the validity of Zimbardo’s Stanford Time Perspective Inventory (STPI) in Indonesian context.

The main objective of this study is to explain the variation of mechanisms of the responsibility of the manager in the company among the advanced capitalist economies. Then we study the impact of these mechanisms on the performance and the value creation in European companies. To reach our goal, we established a final sample composed on average of 284 French, British and German companies quoted in stock exchanges with 2272 annual reports examined during the period from 2005 to 2012. We examined at first the link of causalities between the determining-mechanisms bound to the company such as the characteristics of the board of directors, the composition of the shareholding and the ethics of the company on one side and the profitability of the company on the other side. The results show that the smooth running of the board of directors and its specialist committees are very important determinants of the responsibility of the managers who impact positively the performance and the value creation in the company. Furthermore, our results confirm that the presence of a solid ethical environment within the company will be effective to increase the probability that the managers realize ethical choices in the organizational decision-making. At the second time, we studied the impact of the determining mechanisms bound to the function and to the profile of manager to know its relational links, his remuneration, his training, his age and his experiences about the performance and the value creation in the company. Our results highlight the existence of a negative relation between the relational links of the manager, his very high remuneration and the general profitability of the company. This study is a contribution to the literature on the determining mechanisms of company director's responsibility (Accountability). It establishes an empirical and comparative analysis between three influential countries of Europe, to know France, the United Kingdom and Germany. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=leaders" title="leaders">leaders</a>, <a href="https://publications.waset.org/abstracts/search?q=company%E2%80%99s%20performance" title=" company’s performance"> company’s performance</a>, <a href="https://publications.waset.org/abstracts/search?q=accountability%20mechanisms" title=" accountability mechanisms"> accountability mechanisms</a>, <a href="https://publications.waset.org/abstracts/search?q=corporate%20governance" title=" corporate governance"> corporate governance</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20creation%20of%20firm" title=" value creation of firm"> value creation of firm</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20crisis" title=" financial crisis"> financial crisis</a> </p> <a href="https://publications.waset.org/abstracts/11179/accountability-mechanisms-of-leaders-and-its-impact-on-performance-and-value-creation-comparative-analysis-france-germany-united-kingdom" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11179.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">378</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Identifying Characteristics of Slum in Palembang Riverbanks Area, Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rhaptyalyani%20Herno%20Della">Rhaptyalyani Herno Della</a>, <a href="https://publications.waset.org/abstracts/search?q=Nyimas%20Septi%20Rika%20Putri"> Nyimas Septi Rika Putri</a>, <a href="https://publications.waset.org/abstracts/search?q=Rika%20Nabila"> Rika Nabila</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The growth of population and economic activities in urban areas needs support economic development, needs to be balanced with adequate environmental infrastructure development.

For traffic and emergency monitoring, the essential but challenging task is vehicle detection and tracking in reasonably short time. This purpose needs first of all a powerful dynamic car detector model. In fact, this paper presents an optimized HOG process based on shape and motion parameters fusion. Our proposed approach mains to compute HOG by bloc feature from foreground blobs using configurable research window and pathway in order to overcome the shortcoming in term of computing time of HOG descriptor and improve their dynamic application performance. Indeed we prove in this paper that HOG by bloc descriptor combined with motion parameters is a very suitable car detector which reaches in record time a satisfactory recognition rate in dynamic outside area and bypasses several popular works without using sophisticated and expensive architectures such as GPU and FPGA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=car-detector" title="car-detector">car-detector</a>, <a href="https://publications.waset.org/abstracts/search?q=HOG" title=" HOG"> HOG</a>, <a href="https://publications.waset.org/abstracts/search?q=motion" title=" motion"> motion</a>, <a href="https://publications.waset.org/abstracts/search?q=computing%20time" title=" computing time"> computing time</a> </p> <a href="https://publications.waset.org/abstracts/40704/enhancement-dynamic-cars-detection-based-on-optimized-hog-descriptor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40704.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">323</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> Coordination Behavior, Theoretical Studies, and Biological Activity of Some Transition Metal Complexes with Oxime Ligands</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noura%20Kichou">Noura Kichou</a>, <a href="https://publications.waset.org/abstracts/search?q=Manel%20Tafergguenit"> Manel Tafergguenit</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabila%20Ghechtouli"> Nabila Ghechtouli</a>, <a href="https://publications.waset.org/abstracts/search?q=Zakia%20Hank"> Zakia Hank</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this work is to synthesize, characterize and evaluate the biological activity of two Ligands : glyoxime and dimethylglyoxime, and their metal Ni(II) chelates.

Coronary arteries stenosis and bifurcation angles closely interact for myocardial infarction. We want to use computer-aided design model coupled with computational hemodynamics (CHD) simulation for detecting several types of coronary artery stenosis with different locations in an idealized model for identifying virtual fractional flow reserve (vFFR). The vFFR provides us the information about the severity of stenosis in the computational models. Another goal is that we want to imitate patient-specific computed tomography coronary artery angiography model for constructing our idealized models with different left anterior descending (LAD) and left circumflex (LCx) bifurcation angles. Further, we want to analyze whether the bifurcation angles has an impact on the creation of narrowness in coronary arteries or not. The numerical simulation provides the CHD parameters such as wall shear stress (WSS), velocity magnitude and pressure gradient (PGD) that allow us the information of stenosis condition in the computational domain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CAD" title="CAD">CAD</a>, <a href="https://publications.waset.org/abstracts/search?q=CHD" title=" CHD"> CHD</a>, <a href="https://publications.waset.org/abstracts/search?q=vFFR" title=" vFFR"> vFFR</a>, <a href="https://publications.waset.org/abstracts/search?q=bifurcation%20angles" title=" bifurcation angles"> bifurcation angles</a>, <a href="https://publications.waset.org/abstracts/search?q=coronary%20stenosis" title=" coronary stenosis"> coronary stenosis</a> </p> <a href="https://publications.waset.org/abstracts/85911/simulation-to-detect-virtual-fractional-flow-reserve-in-coronary-artery-idealized-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85911.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">157</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> The Effects of Music and Gender on Recall Ability on College Students: A Study in Students from Universitas Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hestika%20D.%20Waraningrum">Hestika D.

The presence of a distraction is one of the environmental variables that affect recall ability in its capacity in the Short Term Memory. This study was made to see the difference in number of words that was successfully recalled by male participants and female participants with the presence of music as a distraction and also without music as a distraction. Data was taken using an experimental procedure from 75 female and male undergraduate students of Universitas Indonesia. The study design used was a 2x2 Factorial ANOVA, which aimed to see the difference between two variables, which were gender (male vs female) and the presence of a distraction (music serving as a distraction vs absence of music). The results indicated that there were no significant mean differences in the ability to recall between male and female participants. There are no significant mean differences between the presence and the absence of music as a distraction, but a significant interaction was found between gender and distraction with the ability to recall. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=college" title="college">college</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=music" title=" music"> music</a>, <a href="https://publications.waset.org/abstracts/search?q=recall" title=" recall"> recall</a> </p> <a href="https://publications.waset.org/abstracts/91881/the-effects-of-music-and-gender-on-recall-ability-on-college-students-a-study-in-students-from-universitas-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91881.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">231</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 Thymoquinone and Sorafenib Combination on Hepatocellular Carcinoma Cell Line</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabila%20N.%20El-Maraghy">Nabila N.

Aim: Evaluation the modulatory effect of Thymoquinone on HepG2 cells treated with Sorafenib. Methods: Hepatocellular Carcinoma HepG2 cell line was treated with Sorafenib and TQ individually and in combination. The effect of these treatments on cell viability (MTT assay), apoptosis (Expression of Caspase-3) and oxidative markers (GSH content and extent of lipid peroxidation) was determined. Results: When compared the effect of both agents alone and the combination of the IC50 of Sorafenib and the IC50 TQ, the combination resulted in reduction of cell inhibition and apoptosis and antagonize their actions on GSH content and extent of lipid peroxidation which are increased. This study showed potent anti-tumor activity of both TQ and Sorafenib separately on HepG2 but upon combination surprisingly they interacted and give antagonistic effect.

The SCAR method is introduced as a novel approach that combines classical and quantum mechanical principles to elucidate the interaction of electrons with pyrimidine. One of the most fundamental properties characterizing the propagation of a particle in the nuclear medium is its mean free path. Knowledge of the elastic mean free path is essential to accurately predict the effects of radiation on biological matter, as it contributes to the distances between collisions. Additionally, the mean free path plays a role in the interpretation of almost all experiments in which an excited electron moves through a solid. Pyrimidine, the precursor of the pyrimidine bases of DNA, has interesting physicochemical properties, which make it an interesting molecule to study from a fundamental point of view. These include a relatively large dipole polarizability and dipole moment and an electronic charge cloud with a significant spatial extension, which justifies its choice in this present study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=elastic%20mean%20free%20path" title="elastic mean free path">elastic mean free path</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic%20collision" title=" elastic collision"> elastic collision</a>, <a href="https://publications.waset.org/abstracts/search?q=pyrimidine" title=" pyrimidine"> pyrimidine</a>, <a href="https://publications.waset.org/abstracts/search?q=SCAR" title=" SCAR"> SCAR</a> </p> <a href="https://publications.waset.org/abstracts/179786/modeling-the-elastic-mean-free-path-of-electron-collision-with-pyrimidine-the-screen-corrected-additivity-rule-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179786.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">64</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> Prediction of Survival Rate after Gastrointestinal Surgery Based on The New Japanese Association for Acute Medicine (JAAM Score) With Neural Network Classification Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayu%20Nabila%20Kusuma%20Pradana">Ayu Nabila Kusuma Pradana</a>, <a href="https://publications.waset.org/abstracts/search?q=Aprinaldi%20Jasa%20Mantau"> Aprinaldi Jasa Mantau</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomohiko%20Akahoshi"> Tomohiko Akahoshi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The incidence of Disseminated intravascular coagulation (DIC) following gastrointestinal surgery has a poor prognosis. Therefore, it is important to determine the factors that can predict the prognosis of DIC. This study will investigate the factors that may influence the outcome of DIC in patients after gastrointestinal surgery. Eighty-one patients were admitted to the intensive care unit after gastrointestinal surgery in Kyushu University Hospital from 2003 to 2021. Acute DIC scores were estimated using the new Japanese Association for Acute Medicine (JAAM) score from before and after surgery from day 1, day 3, and day 7. Acute DIC scores will be compared with The Sequential Organ Failure Assessment (SOFA) score, platelet count, lactate level, and a variety of biochemical parameters. This study applied machine learning algorithms to predict the prognosis of DIC after gastrointestinal surgery. The results of this study are expected to be used as an indicator for evaluating patient prognosis so that it can increase life expectancy and reduce mortality from cases of DIC patients after gastrointestinal surgery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=the%20survival%20rate" title="the survival rate">the survival rate</a>, <a href="https://publications.waset.org/abstracts/search?q=gastrointestinal%20surgery" title=" gastrointestinal surgery"> gastrointestinal surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=JAAM%20score" title=" JAAM score"> JAAM score</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20network" title=" neural network"> neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=disseminated%20intravascular%20coagulation%20%28DIC%29" title=" disseminated intravascular coagulation (DIC)"> disseminated intravascular coagulation (DIC)</a> </p> <a href="https://publications.waset.org/abstracts/140583/prediction-of-survival-rate-after-gastrointestinal-surgery-based-on-the-new-japanese-association-for-acute-medicine-jaam-score-with-neural-network-classification-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140583.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">258</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">25</span> Study of the Antimicrobial Activity of the Extract of the Eucalyptus camaldulensis stemming from the Algerian Northeast</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meksem%20Nabila">Meksem Nabila</a>, <a href="https://publications.waset.org/abstracts/search?q=Bordjiba%20Ouahiba"> Bordjiba Ouahiba</a>, <a href="https://publications.waset.org/abstracts/search?q=Meraghni%20Messaouda"> Meraghni Messaouda</a>, <a href="https://publications.waset.org/abstracts/search?q=Meksem%20Amara%20Leila"> Meksem Amara Leila</a>, <a href="https://publications.waset.org/abstracts/search?q=Djebar%20Mohhamed%20Reda"> Djebar Mohhamed Reda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The problems of protection of the cultures are being more and more important that they interest great number of farmers and scientists because of the excessive use of the organic phytosanitary products of synthesis that causes fatal damages on the environment. To reduce the inconveniences produced by these pesticides, the use of "biopesticides" originated from plants could be an alternative. The aim of this work is the valuation of a botanical species: Eucalyptus camaldulensis from Northeastern Algeria which extracts are supposed to have an antimicrobial activity, similar to pesticides. The extraction of secondary metabolites from the leaves of E. camaldulensis was realized using methanol and water, and measurements of total polyphenols were made by spectrometric method. Determination of the antimicrobial activity of the extracts at issue was realized in vitro on phyto-pathogenic fungal and bacterial stumps. Tests of comparison were included in the essays by using the chemical pesticidal products of synthesis. The obtained results show that the plant contains polyphenols with an efficiency mattering of the order of 22 %. These polyphenols have a strong fungicidal and bactericidal pesticidal activity against various microbial stumps and the values of the zones of inhibition are more important compared with that obtained in the presence of the chemicals of synthesis (fungicide). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eucalyptus%20camaldulensis" title="eucalyptus camaldulensis">eucalyptus camaldulensis</a>, <a href="https://publications.waset.org/abstracts/search?q=biopesticide" title=" biopesticide"> biopesticide</a>, <a href="https://publications.waset.org/abstracts/search?q=polyphenols" title=" polyphenols"> polyphenols</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20activity" title=" antimicrobial activity"> antimicrobial activity</a> </p> <a href="https://publications.waset.org/abstracts/29478/study-of-the-antimicrobial-activity-of-the-extract-of-the-eucalyptus-camaldulensis-stemming-from-the-algerian-northeast" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29478.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">432</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">24</span> Optimal Location of Unified Power Flow Controller (UPFC) for Transient Stability: Improvement Using Genetic Algorithm (GA)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Basheer%20Idrees%20Balarabe">Basheer Idrees Balarabe</a>, <a href="https://publications.waset.org/abstracts/search?q=Aminu%20Hamisu%20Kura"> Aminu Hamisu Kura</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabila%20Shehu"> Nabila Shehu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As the power demand rapidly increases, the generation and transmission systems are affected because of inadequate resources, environmental restrictions and other losses. The role of transient stability control in maintaining the steady-state operation in the occurrence of large disturbance and fault is to describe the ability of the power system to survive serious contingency in time. The application of a Unified power flow controller (UPFC) plays a vital role in controlling the active and reactive power flows in a transmission line. In this research, a genetic algorithm (GA) method is applied to determine the optimal location of the UPFC device in a power system network for the enhancement of the power-system Transient Stability. Optimal location of UPFC has Significantly Improved the transient stability, the damping oscillation and reduced the peak over shoot.

These cyclones cause a variety of fluctuations along its track including the is the influence in Chlorophyll-a (chl-a) concentration. The main purpose of this paper is to justify this variation pattern. Six Tropical Cyclones (TC) are studied using observational method. The result suggests that there is a noticeable change in productivity after a cyclone passes, when the pre cyclonic and post cyclonic condition is observed. In case of Cyclone Amphan, it shows 1.79 mg/m3 of chlorophyll-a concentration increase after a week of cyclonic occurrence. This change is affected by several attributes such as translation speed, intensity and Ocean Pre-condition, specifically Mixed Layer Depth (MLD). Translation Speed and MLD shows a strong negative correlation with the induced chlorophyll concentration. Whereas the effect of the intensity on a cyclone is not that prominent. It is also found that the period of starting an induction is not same for all cyclone such as in case of Cyclone Amphan, the changes started to occur after one day however for Cyclone Sidr and Cyclone Mora it started after three days. Furthermore, a slightly increase in overall productivity is also observed after a cyclone. In the case of Cyclone Amphan, Hudhud, Phailin it shows a rise up to 0.12 mg/m3 in productivity which decreases gradually taking around the period of two months. On a whole this paper signifies the changes in chlorophyll concentration caused by numerous cyclones and its different characteristics that regulates these changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tropical%20cyclone" title="tropical cyclone">tropical cyclone</a>, <a href="https://publications.waset.org/abstracts/search?q=chlorophyll-a%20concentration" title=" chlorophyll-a concentration"> chlorophyll-a concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20layer%20depth" title=" mixed layer depth"> mixed layer depth</a>, <a href="https://publications.waset.org/abstracts/search?q=translation%20speed" title=" translation speed"> translation speed</a> </p> <a href="https://publications.waset.org/abstracts/159764/cyclone-driven-variation-of-chlorophyll-a-concentration-in-bay-of-bengal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159764.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">88</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">22</span> Implementing Text Using Political and Current Issues to Create Choreography: “The Pledge 2.0”</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Fairul%20Azreen%20bin%20Mohd%20Zahid">Muhammad Fairul Azreen bin Mohd Zahid</a>, <a href="https://publications.waset.org/abstracts/search?q=Melissa%20Querk"> Melissa Querk</a>, <a href="https://publications.waset.org/abstracts/search?q=Aimi%20Nabila%20bt%20Anizaim"> Aimi Nabila bt Anizaim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For this particular research, the focus is based on the practice as research which will produce a choreography as the outcome. The ideas organically develop as an “epiphany” from the meeting, brainstorming, or situation that revolves around surroundings. In this study, the researchers are approaching the national pillar of Malaysia known as ‘Rukun Negara’ to develop a choreographic idea. The concept theory of Speech Act by J.L Austin is used to compose the choreography alongside with national pillar ‘Rukun Negara’ as a guideline for a contemporary work titled, The Pledge 2.0, besides fostering the spirit of unity. These approaches will offer flexibility in creating a choreography piece. The pledge has crossed the boundaries by using texts and heavy issues in choreography developments. It will emphasize the concept of delivering the speech via verbal and nonverbal body language. Besides using the Theory of Speech Acts, the development process of creating this piece will lay the bare normative structure implicit in performance practice. Converging current issues into the final choreographic piece for this research is vital as this research will explore a few choreography methods from different perspectives. Hence, the audience will be able to see the world of dance that always revolves in line with the diachronic process in many ways. The method used in this research is qualitative, which will be used in finding the movement that fits the given facts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=performing%20arts" title="performing arts">performing arts</a>, <a href="https://publications.waset.org/abstracts/search?q=speech%20act" title=" speech act"> speech act</a>, <a href="https://publications.waset.org/abstracts/search?q=performative" title=" performative"> performative</a>, <a href="https://publications.waset.org/abstracts/search?q=nationalism" title=" nationalism"> nationalism</a>, <a href="https://publications.waset.org/abstracts/search?q=choreography" title=" choreography"> choreography</a>, <a href="https://publications.waset.org/abstracts/search?q=politic%20in%20dance" title=" politic in dance"> politic in dance</a> </p> <a href="https://publications.waset.org/abstracts/154834/implementing-text-using-political-and-current-issues-to-create-choreography-the-pledge-20" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154834.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">84</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">21</span> Avidity and IgE versus IgG and IgM in Diagnosis of Maternal Toxoplasmosis </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghada%20A.%20Gamea">Ghada A.

Definitive diagnosis of T. gondii acute infection is therefore critical for the clinical management of a mother and her fetus. This study was conducted on 250 pregnant females in the first trimester who were inpatients or outpatients at Obstetrics and Gynaecology Department at Tanta University Hospital. Screening of the selected females was done for the detection of immunoglobulin (IgG and IgM), and all subjects were submitted to history taking through a questionnaire including personal data, risk factors for Toxoplasma, complaint and history of the present illness. Thirty-eight samples, including 18 IgM +ve and 20 IgM-ve cases were further investigated by the avidity and IgE ELISA tests. The seroprevalence of toxoplasmosis in pregnant women was (42.8%) based on the presence of IgG antibodies in their sera. Contact with cats and consumption of raw or undercooked meat are important risk factors that were associated with toxoplasmosis in pregnant women. By serology, it could be observed that in the IgM +ve group, only one case (5.6%) showed an acute pattern by using the avidity test, though 10 (55.6%) cases were found to be acute by the IgE assay. On the other hand, in the IgM –ve group, 3 (15%) showed low avidity, but none of them was positive by using the IgE assay. In conclusion, there is no single serological test that can be used to confirm whether T. gondii infection is recent or was acquired in the distant past. A panel of tests for detection of toxoplasmosis will certainly have higher discriminatory power than any test alone. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title="diagnosis">diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=serology" title=" serology"> serology</a>, <a href="https://publications.waset.org/abstracts/search?q=seroprevalence" title=" seroprevalence"> seroprevalence</a>, <a href="https://publications.waset.org/abstracts/search?q=toxoplasmosis" title=" toxoplasmosis"> toxoplasmosis</a> </p> <a href="https://publications.waset.org/abstracts/112477/avidity-and-ige-versus-igg-and-igm-in-diagnosis-of-maternal-toxoplasmosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112477.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">153</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> Property of Fermented Sweet Potato Flour and Its Suitability for Composite Noodle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neti%20Yuliana">Neti Yuliana</a>, <a href="https://publications.waset.org/abstracts/search?q=Srisetyani"> Srisetyani</a>, <a href="https://publications.waset.org/abstracts/search?q=Siti%20Nurdjanah"> Siti Nurdjanah</a>, <a href="https://publications.waset.org/abstracts/search?q=Dewi%20Sartika"> Dewi Sartika</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoan%20Martiansari"> Yoan Martiansari</a>, <a href="https://publications.waset.org/abstracts/search?q=Putri%20Nabila"> Putri Nabila</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Naturally sweet potato flour usually requires a modification process to improve its inherent property for expanding its application in food system. The study was aimed to modify sweet potato flour (SPF), to increase its utilization for composite noodle production, trough fermentation of sweet potato slices before its flouring process. Fermentation were prepared with five different starters: pickle brine, Lactobacillus plantarum, Leuconostoc mesenteroides, mixed of Lactobacillus plantarum, Leuconostoc mesenteroides , and mixed of Lactobacillus plantarum, Leuconostoc mesenteroides, and Sacharomyces cerevisiae. Samples were withdrawn every 0, 24, 48, 72 and 96 hours. The fermented flours were characterized for swelling power, solubility, paste transmittance, pH, sensory properties (acidic aroma and whiteness), and the amount of broken composite noodle strips. The results indicated that there was no significant effect of different starters on fermented SPF characteristic and on the amount of broken noodle strip, while length of fermentation significantly affected. Longer fermentation, reaching 48-72 h, increased swelling power, pH, acidic aroma and whiteness of flour and reduced solubility, paste transmittance, and the amount of broken noodle strip. The results suggested that fermentation within 48-72 h period of time could provide great composite SPF for noodle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=starters" title="starters">starters</a>, <a href="https://publications.waset.org/abstracts/search?q=fermented%20flour" title=" fermented flour"> fermented flour</a>, <a href="https://publications.waset.org/abstracts/search?q=sweet%20potato" title=" sweet potato"> sweet potato</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20noodle" title=" composite noodle"> composite noodle</a> </p> <a href="https://publications.waset.org/abstracts/41234/property-of-fermented-sweet-potato-flour-and-its-suitability-for-composite-noodle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41234.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">389</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> Applied of LAWA Classification for Assessment of the Water by Nutrients Elements: Case Oran Sebkha Basin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boualla%20Nabila">Boualla Nabila</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increasing demand on water, either for the drinkable water supply, or for the agricultural and industrial custom, requires a very thorough hydrochemical study to protect better and manage this resource. Oran is relatively a city with the worst quality of the water. Recently, the growing populations may put stress on natural waters by impairing the quality of the water. Campaign of water sampling of 55 points capturing different levels of the aquifer system was done for chemical analyzes of nutriments elements. The results allowed us to approach the problem of contamination based on the largely uniform nationwide approach LAWA (LänderarbeitsgruppeWasser), based on the EU CIS guidance, has been applied for the identification of pressures and impacts, allowing for easy comparison. Groundwater samples were analyzed, also, for physico-chemical parameters such as pH, sodium, potassium, calcium, magnesium, chloride, sulphate, carbonate and bicarbonate. The analytical results obtained in this hydrochemistry study were interpreted using Durov diagram. Based on these representations, the anomaly of high groundwater salinity observed in Oran Sebkha basin was explained by the high chloride concentration and to the presence of inverse cation exchange reaction. Durov diagram plot revealed that the groundwater has been evolved from Ca-HCO3 recharge water through mixing with the pre-existing groundwater to give mixed water of Mg-SO4 and Mg-Cl types that eventually reached a final stage of evolution represented by a Na-Cl water type. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contamination" title="contamination">contamination</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=nutrients%20elements" title=" nutrients elements"> nutrients elements</a>, <a href="https://publications.waset.org/abstracts/search?q=approach%20LAWA" title=" approach LAWA"> approach LAWA</a>, <a href="https://publications.waset.org/abstracts/search?q=durov%20diagram" title=" durov diagram"> durov diagram</a> </p> <a href="https://publications.waset.org/abstracts/36381/applied-of-lawa-classification-for-assessment-of-the-water-by-nutrients-elements-case-oran-sebkha-basin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36381.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">276</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">18</span> Characterization of Volatile Compounds in Meat Lamb Fed in Different Algeria Pasture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabila%20Berrighi">Nabila Berrighi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kaddour%20Bouderoua"> Kaddour Bouderoua</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Khossif"> Maria Khossif</a>, <a href="https://publications.waset.org/abstracts/search?q=Gema%20Nieto"> Gema Nieto</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaspar%20Ros"> Gaspar Ros</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ruminant meat is an important source of nutrients and is also of high sensory value. However, the importance and nature of these characteristics depend on ruminant nutrition. The objective of this study is to assess the effect of two Algerian feeding systems applied in the steppic rearing area of Djelfa and in the highlands one of Tiaret on the growth performance of lambs and on their meat quality, especially on their aroma compounds of meat. At the beginning of the experiment, lambs had an average body weight of 34.04 kg, and 35.40 kg for the group reared at Highland (0% concentrate) and Steppe (30% concentrate), respectively. The incorporation of the concentrated feed in Steppe had a significant effect on slaughter weight compared to lambs fed only on pasture (Highland) (49.72 Kg vs. 42.06 Kg, P<0.05). Beyond the first month, animals from the Steppe one showed better weight gains compared to those from Highland (14.32Kg vs. 8.02 Kg, respectively, P<0,05). After slaughter, samples from the Longissimus thoracis were removed and analyzed. The results point to significant differences in the amounts of many of the predominant volatile compounds between both groups (p<0.05), such as Hexanal, 2-methyl-3-furanthiol and nonanal (8.92 μg/kg vs. 4.57 μg/kg), (8.88 μg/kg vs. 7.45 μg/kg) and (2.09 μ/kg vs. 1.02 μg/kg) associated with smells of green, boiling meat and orange fruit, respectively. These compounds, measured by olfactometry, derived from the oxidation of lipids and appear to be responsible for the characteristic flavor of lamb meat in the steppe compared to that generated by meat from animals from the Highland pastures. The Algerian Steppe ecosystem is very interesting for outdoor sheep breeding, which allows to obtain attractive sensory quality and in the production of typical lamb meat that can be considered as a label. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=falvour" title="falvour">falvour</a>, <a href="https://publications.waset.org/abstracts/search?q=growth%20performance" title=" growth performance"> growth performance</a>, <a href="https://publications.waset.org/abstracts/search?q=lamb%20meat" title=" lamb meat"> lamb meat</a>, <a href="https://publications.waset.org/abstracts/search?q=steppe%20pasture" title=" steppe pasture"> steppe pasture</a> </p> <a href="https://publications.waset.org/abstracts/158117/characterization-of-volatile-compounds-in-meat-lamb-fed-in-different-algeria-pasture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158117.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">101</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">17</span> The Instablity of TetM Gene Encode Tetracycline Resistance Gene in Lactobacillus casei FNCC 0090</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Devi%20Silvian">Sarah Devi Silvian</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanna%20Shobrina%20Iqomatul%20Haq"> Hanna Shobrina Iqomatul Haq</a>, <a href="https://publications.waset.org/abstracts/search?q=Fara%20Cholidatun%20Nabila"> Fara Cholidatun Nabila</a>, <a href="https://publications.waset.org/abstracts/search?q=Agustin%20Krisna%20Wardani"> Agustin Krisna Wardani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bacteria ability to survive in antibiotic is controlled by the presence of gene that encodes the antibiotic resistance protein. The instability of the antibiotic resistance gene can be observed by exposing the bacteria under the lethal dose of antibiotic. Low concentration of antibiotic can induce mutation, which may take a role in bacterial adaptation through the antibiotic concentration. Lactobacillus casei FNCC 0090 is one of the probiotic bacteria that has an ability to survive in tetracycline by expressing the tetM gene. The aims of this study are to observe the possibilities of mutation happened in L.casei FNCC 0090 by exposing in sub-lethal dose of tetracycline and also observing the instability of the tetM gene by comparing the sequence between the wild type and mutant. L.casei FNCC 0090 has a lethal dose in 60 µg/ml, low concentration is applied to induce the mutation, the range from 10 µg/ml, 15 µg/ml, 30 µg/ml, 45 µg/ml, and 50 µg/ml. L.casei FNCC 0090 is exposed to the low concentration from lowest to the highest concentration to induce the adaptation. Plasmid is isolated from the highest concentration culture which is 50 µg/ml by using modified alkali lysis method with the addition of lysozyme. The tetM gene is isolated by using PCR (Polymerase Chain Reaction) method, then PCR amplicon is purified and sequenced. Sequencing is done on both samples, wild type and mutant. Both sequences are compared and the mutations can be traced in the presence of nucleotides changes. The changing of the nucleotides means that the tetM gene is instable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20casei%20FNCC%200090" title="L. casei FNCC 0090">L. casei FNCC 0090</a>, <a href="https://publications.waset.org/abstracts/search?q=probiotic" title=" probiotic"> probiotic</a>, <a href="https://publications.waset.org/abstracts/search?q=tetM" title=" tetM"> tetM</a>, <a href="https://publications.waset.org/abstracts/search?q=tetracycline" title=" tetracycline"> tetracycline</a> </p> <a href="https://publications.waset.org/abstracts/97102/the-instablity-of-tetm-gene-encode-tetracycline-resistance-gene-in-lactobacillus-casei-fncc-0090" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97102.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">188</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> Synthesis, Crystal Structure Characterization, Hirshfeld Surface Analysis and Biological Activities of Two Schiff Base Polymorphs Derived From 2-Aminobenzonitrile</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nesrine%20Benarous">Nesrine Benarous</a>, <a href="https://publications.waset.org/abstracts/search?q=Hassiba%20Bougueria"> Hassiba Bougueria</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabila%20Moussa%20Slimane"> Nabila Moussa Slimane</a>, <a href="https://publications.waset.org/abstracts/search?q=Aouatef%20Cherouana"> Aouatef Cherouana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Crystal polymorphism is important for the synthesis of more potent and bioactive pharmaceutical compounds, including their different properties, such as packing arrangement and conformation. In fact, polymorphism plays a vital role in drug development. Different parameters affect the crystallization and give their degree of freedom. Severalproperties affected polymorphism, like kinetics, thermodynamics, spectroscopy, and mechanical property. Various techniques are used for characterizing polymorphs, are crystallography, morphology, phase transitions, molecular motion, and chemical environment. In this work, crystal structures of two polymorphs (I and II) of the Schiff base (SB) title compound were prepared by condensation reaction. The crystal structures of both polymorphs were determined by single X-ray analysis. The two polymorphs crystallize in two different space groups: P21/c for I and Pbca for II. The dihedral angles between the two phenyl rings are 4.81º for I and 82.27º for II. Both crystal structures are built on the basis of moderate and weak hydrogen bonds, 𝜋-stacking, and halogen⋯halogeninteractions. On the other hand, Hirshfeld surface (HS) analysis indicates that the most important contributions to the crystal packing for the two polymorphs are from Cl⋯H/H⋯Cl, H⋯H, and N⋯H/H⋯N contacts.

Several millions of dollars are being spent at the process site to dehydrate the blockage safely by using chemical inhibitors. We aim to establish national database, which addresses the physical conditions that promotes Qatari natural gas to form gas hydrates in the pipelines. Moreover, we aim to design and test novel hydrate inhibitors that are suitable for Qatari natural gas and its processing facilities. From these perspectives we are aiming to provide more effective and sustainable reservoir utilization and processing of Qatari natural gas. In this work, we present the initial findings of a QNRF funded project, which deals with the natural gas hydrate formation characteristics of Qatari type gas in both experimental (PVTx) and computational (molecular simulations) methods. We present the data from the two fully automated apparatus: a gas hydrate autoclave and a rocking cell. Hydrate equilibrium curves including growth/dissociation conditions for multi-component systems for several gas mixtures that represent Qatari type natural gas with and without the presence of well known kinetic and thermodynamic hydrate inhibitors. Ionic liquids were designed and used for testing their inhibition performance and their DFT and molecular modeling simulation results were also obtained and compared with the experimental results. Results showed significant performance of ionic liquids with up to 0.5 % in volume with up to 2 to 4 0C inhibition at high pressures. <p class="card-text"><strong>Keywords:</strong> <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=natural%20gas" title=" natural gas"> natural gas</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20liquids" title=" ionic liquids"> ionic liquids</a>, <a href="https://publications.waset.org/abstracts/search?q=inhibition" title=" inhibition"> inhibition</a>, <a href="https://publications.waset.org/abstracts/search?q=thermodynamic%20inhibitors" title=" thermodynamic inhibitors"> thermodynamic inhibitors</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetic%20inhibitors" title=" kinetic inhibitors"> kinetic inhibitors</a> </p> <a href="https://publications.waset.org/abstracts/15615/avoiding-gas-hydrate-problems-in-qatar-oil-and-gas-industry-environmentally-friendly-solvents-for-gas-hydrate-inhibition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15615.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">1320</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">14</span> Implementation of a Quality Management Approach in the Laboratory of Quality Control and the Repression of Fraud (CACQE) of the Wilaya of Bechar</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khadidja%20Mebarki">Khadidja Mebarki</a>, <a href="https://publications.waset.org/abstracts/search?q=Naceur%20Boussouar"> Naceur Boussouar</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabila%20Ihaddadene"> Nabila Ihaddadene</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Akermi"> M.

Quality and safety are essential for food security, public health and economic development. The strengthening of food security is essential to increase food security which is considered reached when all individuals can at any time access safe and nutritious food they need to lead healthy and active lives. The objective of this project is to initiate a quality approach in the laboratories of the quality control and the repression of fraud. It will be directed towards the application of good laboratory practices, traceability, management of quality documents (quality, procedures and specification manual) and quality audits. And to prepare the ground for a possible accreditation by ISO 17025 standard of BECHAR laboratory’s. The project will take place in four main stages: 1- Preparation of an audit grid; 2- Realization of a quality audit according to the method of 5 M completed by a section on quality documentation; 3- Drafting of an audit report and proposal for recommendations; 4- Implementation of corrective actions on the ground. This last step consisted in the formalization of the cleaning disinfection plan; work on good hygiene practices, establishment of a mapping of processes and flow charts of the different processes of the laboratory, classifying quality documents and formalizing the process of document management. During the period of the study within the laboratory, all facets of the work were almost appreciated, as we participated in the expertise performed in within it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quality" title="quality">quality</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=ISO%2017025%20accreditation" title=" ISO 17025 accreditation"> ISO 17025 accreditation</a>, <a href="https://publications.waset.org/abstracts/search?q=GLP" title=" GLP"> GLP</a> </p> <a href="https://publications.waset.org/abstracts/21609/implementation-of-a-quality-management-approach-in-the-laboratory-of-quality-control-and-the-repression-of-fraud-cacqe-of-the-wilaya-of-bechar" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21609.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">516</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">13</span> Elastic Collisions of Electrons with DNA and Water From 10 eV to 100 KeV: Scar Macro Investigation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aouina%20Nabila%20Yasmina">Aouina Nabila Yasmina</a>, <a href="https://publications.waset.org/abstracts/search?q=Zine%20El%20Abidine%20Chaoui"> Zine El Abidine Chaoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, understanding the interactions of electrons with the DNA molecule and its components has attracted considerable interest because DNA is the main site damaged by ionizing radiation. The interactions of radiation with DNA induce a variety of molecular damage such as single-strand breaks, double-strand breaks, basic damage, cross-links between proteins and DNA, and others, or the formation of free radicals, which, by chemical reactions with DNA, can also lead to breakage of the strand. One factor that can contribute significantly to these processes is the effect of water hydration on the formation and reaction of radiation induced by these radicals in and / or around DNA. B-DNA requires about 30% by weight of water to maintain its native conformation in the crystalline state. The transformation depends on various factors such as sequence, ion composition, concentration and water activity. Partial dehydration converts it to DNA-A. The present study shows the results of theoretical calculations for positrons and electrons elastic scattering with DNA medium and water over a broad energy range from 10 eV to 100 keV. Indeed, electron elastic cross sections and elastic mean free paths are calculated using a corrected form of the independent atom method, taking into account the geometry of the biomolecule (SCAR macro). Moreover, the elastic scattering of electrons and positrons by atoms of the biomolecule was evaluated by means of relativistic (Dirac) partial wave analysis. Our calculated results are compared with theoretical data available in the literature in the absence of experimental data, in particular for positron. As a central result, our electron elastic cross sections are in good agreement with existing theoretical data in the range of 10 eV to 1 keV. <p class="card-text"><strong>Keywords:</strong> <a
