The crystal structure of the Cu(L)₂(DMF)₂ complex have been determined by X-ray diffraction methods. The Cu(II) lying on an inversion centre is coordinated to six oxygen atoms forming an octahedral elongated. Additionally, the electrochemical behavior of the metal complexe was investigated by cyclic voltammetry at a glassy carbon electrode (GC) in CH₃CN solution, showing the quasi-reversible redox process ascribed to the reduction of the MII/MI couple. The X-ray single crystal structure data of the complex was matched excellently with the optimized monomer structure of the desired compound; Hirschfeld surface analysis supported the packed crystal lattice 3D network intermolecular forces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chalcones" title="chalcones">chalcones</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20voltametry" title=" cyclic voltametry"> cyclic voltametry</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray" title=" X-ray"> X-ray</a>, <a href="https://publications.waset.org/abstracts/search?q=Hirschfeld%20surface" title=" Hirschfeld surface"> Hirschfeld surface</a> </p> <a href="https://publications.waset.org/abstracts/183627/copper-complexe-derivative-of-chalcone-synthesis-characterization-electrochemical-properties-and-xrdhirschfeld-surface" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183627.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">65</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">79</span> Synthesis, Characterization and Catecholase Study of Novel Bidentate Schiff Base Derived from Dehydroacetic Acid</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salima%20Tabti">Salima Tabti</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaima%20Maouche"> Chaima Maouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Tinhinene%20Louaileche"> Tinhinene Louaileche</a>, <a href="https://publications.waset.org/abstracts/search?q=Amel%20Djedouani"> Amel Djedouani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Warad"> Ismail Warad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Novel Schiff base ligand HL has been synthesized by condensation of aromatic amine and DHA. It was characterized by UV-Vis, FT-IR, SM, NMR (1H, 13C) and also by single-crystal X-ray diffraction. The crystal structure shows that compound crystallized in a triclinic system in P-1 space group and with a two unit per cell (Z = 2).The asymmetric unit, contains one independent molecules, the conformation is determined by an intermolecular N-H…O hydrogen bond with an S(6) ring motif. The molecule have an (E) conformation about the C=N bond. The dihedral angles between the phenyl and pyran ring planes is 89.37 (1), the two plans are approximately perpendicular. The catecholase activity of is situ copper complexes of this ligand has been investigated against catechol. The progress of the oxidation reactions was closely monitored over time following the strong peak of catechol using UV-Vis. Oxidation rates were determined from the initial slope of absorbance. time plots, then analyzed by Michaelis-Menten equations. Catechol oxidation reactions were realized using different concentrations of copper acetate and ligand (L/Cu: 1/1, 1/2, 2/1). The results show that all complexes were able to catalyze the oxidation of catechol. Acetate complexes have the highest activity. Catalysis is a branch of chemical kinetics that, more generally, studies the influence of all physical or chemical factors determining reaction rates. It solves a lot of problems in the chemistry reaction process, especially for a green, economic and less polluting chemistry. For this reason, the search for new catalysts for known organic reactions, occupies a very advanced place in the themes proposed by the chemists. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dehydroacetic%20acid" title="dehydroacetic acid">dehydroacetic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=catechol" title=" catechol"> catechol</a>, <a href="https://publications.waset.org/abstracts/search?q=copper" title=" copper"> copper</a>, <a href="https://publications.waset.org/abstracts/search?q=catecholase%20activity" title=" catecholase activity"> catecholase activity</a>, <a href="https://publications.waset.org/abstracts/search?q=x-ray" title=" x-ray"> x-ray</a> </p> <a href="https://publications.waset.org/abstracts/167958/synthesis-characterization-and-catecholase-study-of-novel-bidentate-schiff-base-derived-from-dehydroacetic-acid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167958.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">110</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">78</span> Articulating the Colonial Relation, a Conversation between Afropessimism and Anti-Colonialism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Compton">Thomas Compton</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As Decolonialism becomes an important topic in Political Theory, the rupture between the colonized and the colonist relation has lost attention. Focusing on the anti-colonial activist Madhi Amel, we shall consider his attention to the permanence of the colonial relation and how it preempts Frank Wilderson’s formulation of (white) culturally necessary Anti-Black violence. Both projects draw attention away from empirical accounts of oppression, instead focusing on the structural relation which precipitates them. As Amel says that we should stop thinking of the ‘underdeveloped’ as beyond the colonial relation, Wilderson says we should stop think of the Black rights that have surpassed the role of the slave. However, Amel moves beyond his idol Althusser’s Structuralism toward a formulation of the colonial relation as source of domination. Our analysis will take a Lacanian turn in considering how this non-relation was formulated as a relation how this space of negativity became a ideological opportunity for Colonial domination. Wilderson’s work shall problematise this as we conclude with his criticisms of Structural accounts for the failure to consider how Black social death exists as more than necessity but a cite of white desire. Amel, a Lebanese activist and scholar (re)discovered by Hicham Safieddine, argues colonialism is more than the theft of land, but instead a privatization of collective property and form of investment which (re)produces the status of the capitalist in spaces ‘outside’ the market. Although Amel was a true Marxist-Leninsist, who exposited the economic determinacy of the Colonial Mode of Production, we are reading this account through Alenka Zupančič’s reformulation of the ‘invisible hand job of the market’. Amel points to the signifier ‘underdeveloped’ as buttressed on a pre-colonial epistemic break, as the Western investor (debt collector) sees the (post?) colony narcissistic image. However, the colony can never become site of class conflict, as the workers are not unified but existing between two countries. In industry, they are paid in Colonial subjectivisation, the promise of market (self)pleasure, at home, they are refugees. They are not, as Wilderson states, in the permanent social death of the slave, but they are less than the white worker. This is formulated as citizen (white), non-citizen (colonized), anti-citizen (Black/slave). Here we may also think of how indentured Indians were used as instruments of colonial violence. Wilderson’s aphorism “there is no analogy to anti-Black violence” lays bare his fundamental opposition between colonial and specifically anti-Black violence. It is not only that the debt collector, landowner, or other owners of production pleasures themselves as if their hand is invisible. The absolute negativity between colony and colonized provides a new frontier for desire, the development of a colonial mode of production. An invention inside the colonial structure that is generative of class substitution. We shall explore how Amel ignores the role of the slave but how Wilderson forecloses the history African anti-colonial. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=afropessimism" title="afropessimism">afropessimism</a>, <a href="https://publications.waset.org/abstracts/search?q=fanon" title=" fanon"> fanon</a>, <a href="https://publications.waset.org/abstracts/search?q=marxism" title=" marxism"> marxism</a>, <a href="https://publications.waset.org/abstracts/search?q=postcolonialism" title=" postcolonialism"> postcolonialism</a> </p> <a href="https://publications.waset.org/abstracts/147120/articulating-the-colonial-relation-a-conversation-between-afropessimism-and-anti-colonialism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147120.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">154</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">77</span> VaR Estimation Using the Informational Content of Futures Traded Volume</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amel%20Oueslati">Amel Oueslati</a>, <a href="https://publications.waset.org/abstracts/search?q=Olfa%20Benouda"> Olfa Benouda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> New Value at Risk (VaR) estimation is proposed and investigated.

The biodegradability of these organic compounds was studied using the respirometric method, ‘the standard ISO 9408’. Degradation was followed by analysis of dissolved oxygen using the dissolved oxygen meter over 28 days and the results were compared with that of sodium dodecyl sulphate (SDS). The inoculum used consists of activated sludge taken from the aeration basin of the biological wastewater treatment plant in the city of Boumerdes-Algeria. In addition, the anticorrosive performances of Φ-MES surfactants on a carbon steel "X70" were evaluated in an injection water from a well of Hassi R'mel region- Algeria, known as Baremian water, and are compared to sodium dodecyl sulphate. Two technics, the weight loss and the linear polarization resistance corrosion rate (LPR) are used allowing to investigate the relationships between the concentrations of these synthetized surfactants and their surface properties, surface coverage and inhibition efficiency. Various adsorption isotherm models were used to characterize the nature of adsorption and explain their mechanism. The results show that the MES anionic surfactants was readily biodegradable, degrading faster than SDS, about 88% for C₁₂-MES compared to 66% for the SDS. The length of their carbon chain affects their biodegradability; the longer the chain, the lower the biodegradability. The inhibition efficiency of these surfactants is around 78.4% for C₁₂-MES, 76.60% for C₁₄-MES and 98.19% for C₁₆-MES and increases with their concentration and reaches a maximum value around their critical micelle concentrations ( CMCs). Scanning electron microscopy coupled to energy dispersive X-ray spectroscopy allowed to the visualization of a good adhesion of the protective film formed by the surfactants to the surface of the steel. The studied surfactants show the Langmuirian behavior from which the thermodynamic parameters as adsorption constant (Kads), standard free energy of adsorption (〖∆G〗_ads^0 ) are determined. Interaction of the surfactants with steel surface have involved physisorptions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion" title="corrosion">corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=surfactants" title=" surfactants"> surfactants</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption%20isotherems" title=" adsorption isotherems"> adsorption isotherems</a> </p> <a href="https://publications.waset.org/abstracts/158303/anticorrosive-performances-of-methyl-ester-sulfonates-biodegradable-anionic-synthetized-surfactants-on-carbon-steel-x-70-in-oilfields" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158303.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">97</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">75</span> Structural and Optical Study of Cu doped ZnS Thin Films Nanocrystalline by Chemical Bath Deposition Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Merzouk">Hamid Merzouk</a>, <a href="https://publications.waset.org/abstracts/search?q=D.%20T.%20Talantikite"> D.

Therefore, road security should be managed by vehicles themselves. In this paper, we propose a new Self Organized Trust Management system (SOTM). This system has the responsibility to cut with the spread of false warnings in the network through four principal components: cooperation, trust management, communication and security. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ative%20vehicle" title="ative vehicle">ative vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=cooperation" title=" cooperation"> cooperation</a>, <a href="https://publications.waset.org/abstracts/search?q=trust%20management" title=" trust management"> trust management</a>, <a href="https://publications.waset.org/abstracts/search?q=VANET" title=" VANET"> VANET</a> </p> <a href="https://publications.waset.org/abstracts/42267/sotm-a-new-cooperation-based-trust-management-system-for-vanet" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42267.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">430</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">72</span> A Preliminary Study of the Effects of Abiotic Environmental Variables on Early Diptera Carrion Colonizers in Algiers, Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Taleb">M.

However, they are influenced by weather conditions, and their distribution and activity vary according to different time scales, which can affect the post-mortem interval (PMI) estimation. As no data have been published in Algeria on necrophagous insects visiting corpses, two field surveys were conducted in July 2012 and March 2013 at the National Institute for Criminalistics and Criminology (INCC) using rabbit carcasses (Oryctolagus cuniculus L.). The trials were designed to identify the necrophagous Diptera fauna of Algiers, Algeria and examine their variations according to environmental variables. Four hundred and eighteen Diptera adults belonging to five families were captured during this study. The species which were identified on human corpses in different regions of Algeria were also observed on the rabbit carcasses. Although seasonal variations of the species were observed, their abundance did not significantly vary between the two seasons. In addition to seasonal effects, the ambient temperature, the wind speed, and precipitation affect the number of trapped flies. These conclusions highlight the necessity of considering the environmental factors at a scene to estimate the post-mortem interval accurately. It is hoped that these findings provide basic information regarding the necrophagous Diptera fauna of Algeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forensic%20entomology" title="forensic entomology">forensic entomology</a>, <a href="https://publications.waset.org/abstracts/search?q=necrophagous%20diptera" title=" necrophagous diptera"> necrophagous diptera</a>, <a href="https://publications.waset.org/abstracts/search?q=post-mortem%20interval" title=" post-mortem interval"> post-mortem interval</a>, <a href="https://publications.waset.org/abstracts/search?q=abiotic%20factors" title=" abiotic factors"> abiotic factors</a>, <a href="https://publications.waset.org/abstracts/search?q=Algeria" title=" Algeria"> Algeria</a> </p> <a href="https://publications.waset.org/abstracts/34057/a-preliminary-study-of-the-effects-of-abiotic-environmental-variables-on-early-diptera-carrion-colonizers-in-algiers-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34057.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">388</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">71</span> Smart Trust Management for Vehicular Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amel%20Ltifi">Amel Ltifi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Zouinkhi"> Ahmed Zouinkhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Med%20Salim%20Bouhlel"> Med Salim Bouhlel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Spontaneous networks such as VANET are in general deployed in an open and thus easily accessible environment. Therefore, they are vulnerable to attacks. Trust management is one of a set of security solutions dedicated to this type of networks. Moreover, the strong mobility of the nodes (in the case of VANET) makes the establishment of a trust management system complex.

The main purpose of forensic entomology is to establish the postmortem interval (PMI). In order to estimate the PMI, a forensic entomologist compares the case data with certain reference information relevant to the particular location and time of year. This reference information, including the local distribution of species, are not available in Algeria. Therefore, experiments need to be conducted to provide references for entomological evidence. The objective of this study was to identify the necrophagous flies species which arrive first to carrion using liver baits in Ghardaia, South Algeria. The study was carried out during the spring season in the palmeral of Beni Isguen, Ghardaia which is well known by its hot arid climate. The experiment site (32°28’0’’ N, 3°42’0’’ E), is situated at an altitude of about 526 metres above mean sea level. On April the 4th, 2014, a number of three replicates of liver baited traps were placed in the shade and other three baits were exposed to the sun. Flying insects and larvae were captured and identified. After few minutes, flies invaded the traps which were exposed to the sun. In contrast, no flies were observed in the other traps. A total number of fourty five (45) adult specimens belonging to three taxa were identified: Calliphora vicina (Robineau-Desvoidy, 1830) (Diptera, Calliphoridae) (51.11 %), Lucilia sericata (Meigen, 1826) (Diptera, Calliphoridae) (33.33 %) and Sarcophaga africa (Wiedemann, 1824) (Diptera: Sarcophagidae) (15.55 %). Six hundred and three (603) maggots belonging to two taxa were identified: Calliphora vicina (76.28 %) and Lucilia sericata (23.71 %). The data obtained from this study provides baseline information regarding the carrion fauna of this area. It will also form a basis for similar studies in different geographical and climatological regions of Algeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forensic%20entomology" title="forensic entomology">forensic entomology</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20baits" title=" liver baits"> liver baits</a>, <a href="https://publications.waset.org/abstracts/search?q=necrophagous%20fly" title=" necrophagous fly"> necrophagous fly</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghardaia" title=" Ghardaia"> Ghardaia</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Algeria" title=" South Algeria"> South Algeria</a> </p> <a href="https://publications.waset.org/abstracts/34578/attraction-and-identification-of-early-scavenger-insects-on-shaded-and-sunny-liver-baits-in-a-saharian-region-of-south-central-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34578.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">366</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">64</span> Teachers’ Awareness of the Significance of Lifelong Learning: A Case Study of Secondary School Teachers of Batna - Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bahloul%20Amel">Bahloul Amel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is an attempt to raise the awareness of the stakeholders and the authorities on the sensitivity of Algerian secondary school teachers of English as a Foreign Language about the students’ loss of English language skills learned during formal schooling with effort and at expense and the supposed measures to arrest that loss.

Hence the dc power flow reduces the power flow problem to a set of linear equations, which make the iterative calculation very fast and the GSFD matrix present the effects of single and multiple generator MW change on the transmission line. The effectiveness of the method developed is identified through its application to an IEEE-14 bus test system. The calculation results show excellent performance of the proposed method, in regard to computation time and quality of results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrical%20power%20system%20security" title="electrical power system security">electrical power system security</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20dispatch" title=" economic dispatch"> economic dispatch</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity%20matrix" title=" sensitivity matrix"> sensitivity matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=labview" title=" labview"> labview</a> </p> <a href="https://publications.waset.org/abstracts/36292/secured-power-flow-algorithm-including-economic-dispatch-with-gsdf-matrix-using-labview" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36292.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">489</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">62</span> Mean Velocity Modeling of Open-Channel Flow with Submerged Vegetation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mabrouka%20Morri">Mabrouka Morri</a>, <a href="https://publications.waset.org/abstracts/search?q=Amel%20Soualmia"> Amel Soualmia</a>, <a href="https://publications.waset.org/abstracts/search?q=Philippe%20Belleudy"> Philippe Belleudy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Vegetation affects the mean and turbulent flow structure. It may increase flood risks and sediment transport. Therefore, it is important to develop analytical approaches for the bed shear stress on vegetated bed, to predict resistance caused by vegetation. In the recent years, experimental and numerical models have both been developed to model the effects of submerged vegetation on open-channel flow. In this paper, different analytic models are compared and tested using the criteria of deviation, to explore their capacity for predicting the mean velocity and select the suitable one that will be applied in real case of rivers. The comparison between the measured data in vegetated flume and simulated mean velocities indicated, a good performance, in the case of rigid vegetation, whereas, Huthoff model shows the best agreement with a high coefficient of determination (R2=80%) and the smallest error in the prediction of the average velocities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytic%20models" title="analytic models">analytic models</a>, <a href="https://publications.waset.org/abstracts/search?q=comparison" title=" comparison"> comparison</a>, <a href="https://publications.waset.org/abstracts/search?q=mean%20velocity" title=" mean velocity"> mean velocity</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetation" title=" vegetation"> vegetation</a> </p> <a href="https://publications.waset.org/abstracts/21381/mean-velocity-modeling-of-open-channel-flow-with-submerged-vegetation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21381.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">61</span> Students’ Awareness of the Use of Poster, Power Point and Animated Video Presentations: A Case Study of Third Year Students of the Department of English of Batna University</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bahloul%20Amel">Bahloul Amel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study debates students’ perceptions of the use of technology in learning English as a Foreign Language.

In the present work, ZnO thin films were prepared by ultrasonic spray pyrolysis by using different precursors namely: Acetate, chloride and zinc nitrate in order to investigate their influence on ZnO photocatalytic activity. The films crystalline structure was studied by mean of X-ray diffraction measurements (XRD) and the films surface morphology by Scanning Electron Microscopy (SEM). The films optical properties were studied by mean of UV–visible spectroscopy. The prepared films were tested for the degradation of the red reactive dye largely used in textile industry. As a result, we found that the zinc nitrate is the best precursor to prepare ZnO thin films suitable for a good photocatalytic activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=precursor" title="precursor">precursor</a>, <a href="https://publications.waset.org/abstracts/search?q=thins%20films" title=" thins films"> thins films</a>, <a href="https://publications.waset.org/abstracts/search?q=spray%20pyrolysis" title=" spray pyrolysis"> spray pyrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc%20oxide" title=" zinc oxide"> zinc oxide</a> </p> <a href="https://publications.waset.org/abstracts/36904/zinc-oxide-thin-films-deposition-by-spray-pyrolysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36904.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">327</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">59</span> Forensic Entomology in Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meriem%20Taleb">Meriem Taleb</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghania%20Tail"> Ghania Tail</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Zohra%20Kara"> Fatma Zohra Kara</a>, <a href="https://publications.waset.org/abstracts/search?q=Brahim%20Djedouani"> Brahim Djedouani</a>, <a href="https://publications.waset.org/abstracts/search?q=T.%20Moussa"> T. Moussa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Forensic entomology is the use of insects and their arthropod relatives as silent witnesses to aid legal investigations by interpreting information concerning a death. The main purpose of forensic entomology is to establish the postmortem interval or PMI Postmortem interval is a matter of crucial importance in the investigations of homicide and other untimely deaths when the body found is after three days. Forensic entomology has grown immensely as a discipline in the past thirty years. In Algeria, forensic entomology was introduced in 2010 by the National Institute for Criminalistics and Criminology of the National Gendarmerie (NICC). However, all the work that has been done so far in this growing field in Algeria has been unknown at both the national and international levels. In this context, the aim of this paper is to describe the state of forensic entomology in Algeria. The Laboratory of Entomology of the NICC is the only one of its kind in Algeria. It started its activities in 2010, consisting of two specialists. The main missions of the laboratory are estimation of the PMI by the analysis of entomological evidence, and determination if the body was moved. Currently, the laboratory is performing different tasks such as the expert work required by investigators to estimate the PMI using the insects. The estimation is performed by the accumulated degree days method (ADD) in most of the cases except for those where the cadaver is in dry decay. To assure the quality of the entomological evidence, crime scene personnel are trained by the laboratory of Entomology of the NICC. Recently, undergraduate and graduate students have been studying carrion ecology and insect activity in different geographic locations of Algeria using rabbits and wild boar cadavers as animal models. The Laboratory of Entomology of the NICC has also been involved in some of these research projects. Entomotoxicology experiments are also conducted with the collaboration of the Toxicology Department of the NICC. By dint of hard work that has been performed by the Laboratory of Entomology of the NICC, official bodies have been adopting more and more the use of entomological evidence in criminal investigations in Algeria, which is commendable. It is important, therefore, that steps are taken to fill in the gaps in the knowledge necessary for entomological evidence to have a useful future in criminal investigations in Algeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forensic%20entomology" title="forensic entomology">forensic entomology</a>, <a href="https://publications.waset.org/abstracts/search?q=corpse" title=" corpse"> corpse</a>, <a href="https://publications.waset.org/abstracts/search?q=insects" title=" insects"> insects</a>, <a href="https://publications.waset.org/abstracts/search?q=postmortem%20interval" title=" postmortem interval"> postmortem interval</a>, <a href="https://publications.waset.org/abstracts/search?q=expertise" title=" expertise"> expertise</a>, <a href="https://publications.waset.org/abstracts/search?q=Algeria" title=" Algeria"> Algeria</a> </p> <a href="https://publications.waset.org/abstracts/34230/forensic-entomology-in-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34230.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">407</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">58</span> Effect of Temperature on the Structural and Optical Properties of ZnS Thin Films Obtained by Chemical Bath Deposition in Acidic Medium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Merzouk">Hamid Merzouk</a>, <a href="https://publications.waset.org/abstracts/search?q=Dajhida%20Talantikite"> Dajhida Talantikite</a>, <a href="https://publications.waset.org/abstracts/search?q=Amel%20Tounsi"> Amel Tounsi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Thin films of ZnS have been deposited by chemical route into acidic medium.

Thus, undetected machine faults may cascade in it failure, which in turn may cause production shutdowns. Such shutdowns are costly in terms of lost production time, maintenance costs, and wasted raw materials. Doubly fed induction generators are used mainly for wind energy conversion in MW power plants. This paper presents a detection of an inter turn stator fault in a doubly fed induction machine whose stator and rotor are supplied by two pulse width modulation (PWM) inverters.

Methods: The current study consists of a cross-sectional online survey of self-reporting HIV-negative sexual minority men (SMM) residing in PR. Results: In this sample, there were no differences between urban and rural-based services for SMM. However, more than half of the sample reported that they have never disclosed their gender identity and sexual practices to a physician. Conclusion: HIV is a significant public health concern affecting Latinos/Hispanics in the U.S. Findings in this paper can have implications for HIV prevention services in PR specifically, as few studies have directly focused on the impact of HIV and health care services in PR outside of the continental U.S. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HIV" title="HIV">HIV</a>, <a href="https://publications.waset.org/abstracts/search?q=Puerto%20Rico" title=" Puerto Rico"> Puerto Rico</a>, <a href="https://publications.waset.org/abstracts/search?q=infectious%20diseases" title=" infectious diseases "> infectious diseases </a>, <a href="https://publications.waset.org/abstracts/search?q=public%20health" title=" public health"> public health</a> </p> <a href="https://publications.waset.org/abstracts/138943/geographic-differences-in-access-to-hiv-prevention-services-and-care-among-sexual-minority-men-in-puerto-rico" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138943.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">53</span> Evaluation of Activity of Anacyclus Pyrethrum Methanolic Extract on Acute Inflammation Induced in Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dalila%20Bouamra">Dalila Bouamra</a>, <a href="https://publications.waset.org/abstracts/search?q=Chekib%20Arslane%20Baki"> Chekib Arslane Baki</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelhamid%20Bouchebour"> Abdelhamid Bouchebour</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatiha%20Koussa"> Fatiha Koussa</a>, <a href="https://publications.waset.org/abstracts/search?q=Amel%20Benamara"> Amel Benamara</a>, <a href="https://publications.waset.org/abstracts/search?q=Seoussen%20Kada"> Seoussen Kada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The activity of methanolic extract from Anacyclus pyrethrum was evaluated using λ-carrageenan 1% induced paw edema in Wistar Albinos rats.

The plant extract has an impact on the loss ratio of granulocytes that have invaded the stomach after a period of inflammation at a dose of 600 mg/kg body weight. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inflammation" title="inflammation">inflammation</a>, <a href="https://publications.waset.org/abstracts/search?q=Anacyclus%20pyrethrum" title=" Anacyclus pyrethrum"> Anacyclus pyrethrum</a>, <a href="https://publications.waset.org/abstracts/search?q=gastritis" title=" gastritis"> gastritis</a>, <a href="https://publications.waset.org/abstracts/search?q=Wistar%20Albinos%20rats" title=" Wistar Albinos rats"> Wistar Albinos rats</a> </p> <a href="https://publications.waset.org/abstracts/17054/evaluation-of-activity-of-anacyclus-pyrethrum-methanolic-extract-on-acute-inflammation-induced-in-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17054.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">487</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">52</span> Development of Extemporaneous Pediatric Syrup of Prednisone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amel%20Chenafa">Amel Chenafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Sihem%20Boulenouar"> Sihem Boulenouar</a>, <a href="https://publications.waset.org/abstracts/search?q=Linda%20Aoued"> Linda Aoued</a>, <a href="https://publications.waset.org/abstracts/search?q=Imane%20Sediri"> Imane Sediri</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismahan%20Djebbar"> Ismahan Djebbar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Adil%20Selka"> Mohamed Adil Selka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The specialties intended for adults are often inadequate marketed for pediatric use, such as for a galenic form or in the dosage. For an industrial, development of a pediatric drug is confronted to various problems. So, the hospital pharmacies have to respond to adaptation needs of pharmaceutical forms for pediatric use. The objective of our work is to develop an oral form of prednisone for pediatric use since no adapted form to children is commercialized. Materials and Methods: Therefore an extemporaneous syrup of prednisone was prepared at the concentration of 0,5mg/ml from 5mg tablets and stored in amber glass bottles. Organoleptic and microbiological stability was studied in two temperatures: 5°C and 25°C, and evaluated at D0, D15, and D30. Results: No organoleptic changes have been detected on the syrup conserved at 25 and 5°C. The results show that there is no presence of bacteria, yeasts, and molds in the syrups stored at both temperatures during the analysis period. Conclusion: Sheltered from light, the developed syrup of prednisone remained stable at room temperature and/or refrigerator for 30 days. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extemporaneous%20syrup" title="extemporaneous syrup">extemporaneous syrup</a>, <a href="https://publications.waset.org/abstracts/search?q=pediatric%20drug" title=" pediatric drug"> pediatric drug</a>, <a href="https://publications.waset.org/abstracts/search?q=prednisone" title=" prednisone"> prednisone</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a> </p> <a href="https://publications.waset.org/abstracts/32721/development-of-extemporaneous-pediatric-syrup-of-prednisone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32721.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">386</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51</span> Dental Management Particularities of Werner Syndrome: A Report of Two Cases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emna%20Abid">Emna Abid</a>, <a href="https://publications.waset.org/abstracts/search?q=Linda%20Chebbi"> Linda Chebbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yosra%20Mabrouk"> Yosra Mabrouk</a>, <a href="https://publications.waset.org/abstracts/search?q=Amel%20Labidi"> Amel Labidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Lamia%20Mansour"> Lamia Mansour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Werner syndrome (WS) is a rare genetic disorder inherited in an autosomal recessive pattern characterized by accelerated aging. While extensive research has been conducted on its systemic manifestations, the specific dental implications of WS remain poorly understood. The medical history and the oral health status of two patients diagnosed with WS were detailed. Our findings revealed a high prevalence of dental problems in both patients, including periodontitis, xerostomia, and temporomandibular joint disorders. This article aims to investigate the dental challenges faced by individuals with WS as well as the prosthetic options envisaged through two clinical cases contributing to a deeper understanding of the dental implications of WS and to choose the appropriate prosthetic solution in this population. Future research should focus on larger scale studies and clinical trials to validate these proposed strategies. <p class="card-text"><strong>Keywords:</strong> <a
