The body of criticism on Saadi’s works suggests that his biography provides no clear and valid information to judge about the extent to which Saadi acted what he preached. His moral teachings depict a sort of individual and social morality which is defined in relation to power and falls in the category of political ethics. Political ethics appear as for the noble and the subordinate in Gulistan and Boustan. Ethics for the noble include all his teachings for governors and rulers in eulogies. On the other hand, ethics for the subordinate include all his suggestions for the public in relation to power position. Here, Saadi puts forward some conservative recommendations that trigger some contemporary critical commentaries. However, there are some cases where he takes up a third person narrative position to narrate the story of a king and a mendicant. In these stories, the mendicant is a witty man with bitter criticism on society, implying that one should relinquish earthly pleasures and advantages if he wants his criticism to be acceptable. First person narratives fall in two categories determinate and indeterminate narratives. Indirect speeches reflecting biographical facts are indeterminate narratives which give no information about the poet’s personality. Other narratives are more of an autobiography that report probable observations. These latter narratives demonstrate Saadi as a man quick at repartee that feels free to disclose his poverty and some cases of impiety. Therefore, they provide no idealized picture of the poet in terms of ethical principles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saadi" title="Saadi">Saadi</a>, <a href="https://publications.waset.org/abstracts/search?q=ethics" title=" ethics"> ethics</a>, <a href="https://publications.waset.org/abstracts/search?q=Boustan" title=" Boustan"> Boustan</a>, <a href="https://publications.waset.org/abstracts/search?q=Gulistan" title=" Gulistan"> Gulistan</a>, <a href="https://publications.waset.org/abstracts/search?q=first-person%20narrative" title=" first-person narrative"> first-person narrative</a> </p> <a href="https://publications.waset.org/abstracts/36932/saadi-the-matter-of-reality-and-imagination" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36932.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">402</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Pathology of the Partridge Gambra Alectoris barbara in a Semi-Captive Breeding in the Algiers Sahel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Saadi-Idouhar">H.

Game birds are of interest because they play an important role for hunting federations and for the economy of a country. The breeding of indigenous breeds is necessary because it is of great economic interest. However, gambra breeding in the hunting centre of Zeralda (northern west of Algiers) is not easy, several diseases affecting Perdreaux and reproducing adults have been noted. Most of the diseases observed are parasitic in origin. This study is conducted during the 2010 breeding season. It is based on the autopsy of cadavers collected at the hunting centre and parasitic coprology. Indeed, the flotation enrichment method has identified several parasites such as Eimeria spp., Capillaria spp., and Ascaridia spp. Autopsied corpses show the importance of two major diseases, syngamosis caused to Syngamus trachea and histomonosis caused to Histomonas meleagridis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=partridge" title="partridge">partridge</a>, <a href="https://publications.waset.org/abstracts/search?q=livestock" title=" livestock"> livestock</a>, <a href="https://publications.waset.org/abstracts/search?q=eggs" title=" eggs"> eggs</a>, <a href="https://publications.waset.org/abstracts/search?q=affections%20pathology" title=" affections pathology"> affections pathology</a> </p> <a href="https://publications.waset.org/abstracts/101106/pathology-of-the-partridge-gambra-alectoris-barbara-in-a-semi-captive-breeding-in-the-algiers-sahel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101106.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">180</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> Job in Modern Arabic Poetry: A Semantic and Comparative Approach to Two Poems Referring to the Poet Al-Sayyab</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeries%20Khoury">Jeries Khoury</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of legendary, folkloric and religious symbols is one of the most important phenomena in modern Arabic poetry. Interestingly enough, most of the modern Arabic poetry’s pioneers were so fascinated by the biblical symbols and they managed to use many modern techniques to make these symbols adequate for their personal life from one side and fit to their Islamic beliefs from the other. One of the most famous poets to do so was al-Sayya:b. The way he employed one of these symbols ‘job’, the new features he adds to this character and the link between this character and his personal life will be discussed in this study. Besides, the study will examine the influence of al-Sayya:b on another modern poet Saadi Yusuf, who, following al-Sayya:b, used the character of Job in a special way, by mixing its features with al-Sayya:b’s personal features and in this way creating a new mixed character. A semantic, cultural and comparative analysis of the poems written by al-Sayya:b himself and the other poets who evoked the mixed image of al-Sayya:b-Job, can reveal the changes Arab poets made to the original biblical figure of Job to bring it closer to Islamic culture. The paper will make an intensive use of intertextuality idioms in order to shed light on the network of relations between three kinds of texts (indeed three <span dir="RTL">‘</span><em>palimpsests</em>’: 1- biblical- the primary text; 2- poetic- al-Syya:b’s secondary version; 3- re-poetic- Sa’di Yusuf’s tertiary version). The bottom line in this paper is that that al-Sayya:b was directly influenced by the dramatic biblical story of Job more than the brief Quranic version of the story. In fact, the ‘new’ character of Job designed by al-Sayya:b himself differs from the original one in many aspects that we can safely say it is the Sayyabian-Job that cannot be found in the poems of any other poets, unless they are evoking the own tragedy of al-Sayya:b himself, like what Saadi Yusuf did. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arabic%20poetry" title="Arabic poetry">Arabic poetry</a>, <a href="https://publications.waset.org/abstracts/search?q=intertextuality" title=" intertextuality"> intertextuality</a>, <a href="https://publications.waset.org/abstracts/search?q=job" title=" job"> job</a>, <a href="https://publications.waset.org/abstracts/search?q=meter" title=" meter"> meter</a>, <a href="https://publications.waset.org/abstracts/search?q=modernism" title=" modernism"> modernism</a>, <a href="https://publications.waset.org/abstracts/search?q=symbolism" title=" symbolism"> symbolism</a> </p> <a href="https://publications.waset.org/abstracts/101263/job-in-modern-arabic-poetry-a-semantic-and-comparative-approach-to-two-poems-referring-to-the-poet-al-sayyab" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101263.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">199</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Forming for Confirmation of Predicted Epoxy Forming Composition Range in Cr-Zn System </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Foad%20Saadi">Foad Saadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim of this work was to determine the approximate Epoxy forming composition range of Cr-Zn system for the composites produced by forming compositing.

The number of considered samples is 33 eggs. The duration of the incubation is of 18 days. Unhatched eggs and eggs eliminated previously at the time of the mirage are collected and forwarded to the laboratories of microbiology and parasitology. The average weight of the eggs of the Barbary Partridge vary much [20.08 ± 1.81 g. (2006) < Pm < 20.82 ± 2,11g. (2008)]. The percentage of unhatched eggs varies between 9.3% in 2005 and 15.55% in 2007. It appears that the rate of embryonic mortality is slightly higher compared to that of infertile eggs. Microbiological analysis of unhatched eggs showed the presence of pathogenic germs such as lute Chryseomonas luteola. Chryseomonas ola and Escherichia coli. As against the parasites research is negative. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=barbary%20partridge" title="barbary partridge">barbary partridge</a>, <a href="https://publications.waset.org/abstracts/search?q=unhatched%20eggs" title=" unhatched eggs"> unhatched eggs</a>, <a href="https://publications.waset.org/abstracts/search?q=embryo%20mortality" title=" embryo mortality"> embryo mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=pathogenic%20germs" title=" pathogenic germs"> pathogenic germs</a> </p> <a href="https://publications.waset.org/abstracts/23271/influence-of-some-parameters-on-embryonic-mortality-of-barbary-partridge-alectoris-barbara-in-a-semi-captive-breeding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23271.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">535</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Correlation of the Biometric Parameters of Eggs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Zenia">S.

A large amount of solar radiation is converted to heat, which should be dissipated by any cooling techniques. In the present study, the cooling is achieved by inserting triangular ribs in the duct. A comprehensive two-dimensional thermo-fluid model for the effective cooling of PV cells has been developed. It has been first carefully validated against experimental and numerical results available in the literature. A parametric analysis was then carried out about the influence of the number and size of the ribs, wind speed, solar irradiance and inlet fluid velocity on the average solar cell and outlet air temperatures as well as the thermal and electrical efficiencies of the module. Results indicated that the use of triangular ribbed channels is a very effective cooling technique, which significantly reduces the average temperature of the PV cell, especially when increasing the number of ribs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=effective%20cooling" title="effective cooling">effective cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20modeling" title=" numerical modeling"> numerical modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20cell" title=" photovoltaic cell"> photovoltaic cell</a>, <a href="https://publications.waset.org/abstracts/search?q=triangular%20ribs" title=" triangular ribs"> triangular ribs</a> </p> <a href="https://publications.waset.org/abstracts/90057/effective-cooling-of-photovoltaic-solar-cells-by-inserting-triangular-ribs-a-numerical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90057.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">177</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">23</span> A Sufficient Fuzzy Controller for Improving the Transient Response in Electric Motors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aliasghar%20Baziar">Aliasghar Baziar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Masoumi"> Hassan Masoumi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Ale%20Saadi"> Alireza Ale Saadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The control of the response of electric motors plays a significant role in the damping of transient responses. In this regard, this paper presents a static VAR compensator (SVC) based on a fuzzy logic which is applied to an industrial power network consisting of three phase synchronous, asynchronous and DC motor loads. The speed and acceleration variations of a specific machine are the inputs of the proposed fuzzy logic controller (FLC). In order to verify the effectiveness and proficiency of the proposed Fuzzy Logic based SVC (FLSVC), several non-linear time-domain digital simulation tests are performed. The proposed fuzzy model can properly control the response of electric motors. The results show that the FLSVC is successful to improve the voltage profile significantly over a wide range of operating conditions and disturbances thus improving the overall dynamic performance of the network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20logic%20controller" title="fuzzy logic controller">fuzzy logic controller</a>, <a href="https://publications.waset.org/abstracts/search?q=VAR%20compensator" title=" VAR compensator"> VAR compensator</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20cage%20asynchronous%20motor" title=" single cage asynchronous motor"> single cage asynchronous motor</a>, <a href="https://publications.waset.org/abstracts/search?q=DC%20motor" title=" DC motor"> DC motor</a> </p> <a href="https://publications.waset.org/abstracts/53163/a-sufficient-fuzzy-controller-for-improving-the-transient-response-in-electric-motors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53163.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">628</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> Improvement of the Aerodynamic Behaviour of a Land Rover Discovery 4 in Turbulent Flow Using Computational Fluid Dynamics (CFD)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Al-Saadi">Ahmed Al-Saadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Hassanpour"> Ali Hassanpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Tariq%20Mahmud"> Tariq Mahmud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of this study is to investigate ways to reduce the aerodynamic drag coefficient and to increase the stability of the full-size Sport Utility Vehicle using three-dimensional Computational Fluid Dynamics (CFD) simulation.

These reduction aerodynamic techniques were tested individually or in combination to get the best design. All new models have the same capacity and comfort of the baseline model. Uniform freestream velocity of the air at inlet ranging from 28 m/s to 40 m/s was used. ANSYS Fluent software (version 16.0) was used to simulate all models.

Advanced materials, because of their excellent combination of high specific strength, lightweight, and general corrosion resistance. In fact, chemical wear resistance of aero-engine alloy provide a serious challenge for cutting tool material during the machining process. The reduction in cutting temperature distributions leads to an increase in tool life and a decrease in wear rate. Hence, the chip morphology and segmentation play a predominant role in determining machinability and tool wear during the machining process. The result of low thermal conductivity and diffusivity of this alloy in the concentration of high temperatures at the tool-work-piece and tool-chip interface. Consequently, the chip morphology is very important in the study of machinability of metals as well as the study of cutting tool wear. Otherwise, the result will be accelerating tool wear, increasing manufacturing cost and time consuming. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=machinability" title="machinability">machinability</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20alloy%20%28ti-6al-4v%29" title=" titanium alloy (ti-6al-4v)"> titanium alloy (ti-6al-4v)</a>, <a href="https://publications.waset.org/abstracts/search?q=chip%20formation" title=" chip formation"> chip formation</a>, <a href="https://publications.waset.org/abstracts/search?q=milling%20process" title=" milling process"> milling process</a> </p> <a href="https://publications.waset.org/abstracts/31189/study-of-machinability-for-titanium-alloy-ti-6al-4v-through-chip-formation-in-milling-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31189.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">450</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> Ab Initio Studies of Structural and Thermal Properties of Aluminum Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Saadi">M.

Several living organisms can come into contact with it: bacteria, viruses, protozoa, fungi, mites, and insects. In Algeria, many beekeepers have reported unusual mortality of local bees, loss of foragers and significant losses of their livestock. Despite the presence of a varied honey-bearing flora and a favourable Mediterranean climate, honey production remains low. This phenomenon can be attributed to the excess winter mortality, but also to the increasing difficulties that beekeepers face in maintaining healthy bee colonies, particularly bee diseases and their transmission facilitated by trade and beekeeping practices. Our survey is based on a questionnaire composed of several parts. The results obtained show that the disease that most affects bees according to beekeepers is varroa mite with 93% followed by fungi with 26%. The most replied enemy of bees is the false ringworm with 73%, followed by the bee-eater with 63%. Our goal is to determine the causes of this low production in two areas: Bejaia and Tizi-Ouzou. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diseases" title="diseases">diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=Apis%20mellifera%20L." title=" Apis mellifera L."> Apis mellifera L.</a>, <a href="https://publications.waset.org/abstracts/search?q=varroa" title=" varroa"> varroa</a>, <a href="https://publications.waset.org/abstracts/search?q=European%20foulbrood" title=" European foulbrood"> European foulbrood</a> </p> <a href="https://publications.waset.org/abstracts/100968/investigation-of-diseases-and-enemies-of-bees-of-breeding-apis-mellifera-intermissa-buttel-reepen-1906" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100968.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">161</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> Design for Safety: Safety Consideration in Planning and Design of Airport Airsides</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maithem%20Al-Saadi">Maithem Al-Saadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20An"> Min An </a> </p> <p class="card-text"><strong>Abstract:</strong></p> During airport planning and design stages, the major issues of capacity and safety in construction and operation of an airport need to be taken into consideration. The airside of an airport is a major and critical infrastructure that usually consists of runway(s), taxiway system, and apron(s) etc., which have to be designed according to the international standards and recommendations, and local limitations to accommodate the forecasted demands. However, in many cases, airport airsides are suffering from unexpected risks that occurred during airport operations. Therefore, safety risk assessment should be applied in the planning and design of airsides to cope with the probability of risks and their consequences, and to make decisions to reduce the risks to as low as reasonably practicable (ALARP) based on safety risk assessment. This paper presents a combination approach of Failure Modes, Effect, and Criticality Analysis (FMECA), Fuzzy Reasoning Approach (FRA), and Fuzzy Analytic Hierarchy Process (FAHP) to develop a risk analysis model for safety risk assessment. An illustrated example is used to the demonstrate risk assessment process on how the design of an airside in an airport can be analysed by using the proposed safety design risk assessment model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airport%20airside%20planning%20and%20design" title="airport airside planning and design">airport airside planning and design</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20for%20safety" title=" design for safety"> design for safety</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20reasoning%20approach" title=" fuzzy reasoning approach"> fuzzy reasoning approach</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20AHP" title=" fuzzy AHP"> fuzzy AHP</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20assessment" title=" risk assessment"> risk assessment</a> </p> <a href="https://publications.waset.org/abstracts/40321/design-for-safety-safety-consideration-in-planning-and-design-of-airport-airsides" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40321.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">365</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> Morphometric Study of the Eggs of Pheasant Eggs Phasianus colchicus (Aves, Phasianidae)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Zenia">S.

The present study was conducted in an experimental breeding. The objective of this work is to know the quality of the eggs of this bird. A total of 938 eggs were collected. To deepen the knowledge about the characteristics of external shell quality, biometric parameters were studied, among them we find the weight with a mean value of 29.2± 2, 24 g. Egg length (mm) and egg width (mm) mean value are respectively 43.01 ± 1,84 cm and 34.05 ± 1,44cm. The volume and shape index of eggs obtained are respectively 25,63±2,88cm3 and 79.00 ± 3%, shell index which recorded an average of 68%. Water loss recorded is 13%. Note that all these parameters and others may influence hatching. The analysis of variance applied for the comparison of egg weight shows that there is no significant difference in the same form factor (P> 0.05). Otherwise, the comparison test used shows a significant difference with P <0.05 for length, width, volume, density, indices of shell and water loss of eggs between the different. Indeed, several factors may explain the difference as the absence of sorting eggs during incubation and other factors that will be exposing later. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analysis%20of%20variance" title="analysis of variance">analysis of variance</a>, <a href="https://publications.waset.org/abstracts/search?q=egg" title=" egg"> egg</a>, <a href="https://publications.waset.org/abstracts/search?q=hatching" title=" hatching"> hatching</a>, <a href="https://publications.waset.org/abstracts/search?q=morphometry%20of%20eggs%20Phaisan%20%28Phasianus%20colchicus.L.%29" title=" morphometry of eggs Phaisan (Phasianus colchicus.L.)"> morphometry of eggs Phaisan (Phasianus colchicus.L.)</a> </p> <a href="https://publications.waset.org/abstracts/22873/morphometric-study-of-the-eggs-of-pheasant-eggs-phasianus-colchicus-aves-phasianidae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22873.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">609</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> Impact of Coccidia on Mortality and Weight Growth in Japanese Quail Coturnix japonica (Aves, Phasianidae) in Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amina%20Smai">Amina Smai</a>, <a href="https://publications.waset.org/abstracts/search?q=Fairouz%20Haddadj"> Fairouz Haddadj</a>, <a href="https://publications.waset.org/abstracts/search?q=Habiba%20Saadi-Idouhar"> Habiba Saadi-Idouhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Meriem%20Aissi"> Meriem Aissi</a>, <a href="https://publications.waset.org/abstracts/search?q=Safia%20Zenia"> Safia Zenia</a>, <a href="https://publications.waset.org/abstracts/search?q=Salaheddine%20Doumandji"> Salaheddine Doumandji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Coccidiosis is a very common intestinal parasitic disease caused by a worldwide distributed protozoan of the genus Eimeria. This disease is very common in young birds beyond the second week of life, especially in land-based breeding. The study was carried out in a hunting center of Zeralda located in the north-east of Algiers. The objective of our work is to study the evolution of coccidiosis in quails from 1 to 35 days old by collecting their droppings daily. These are analyzed in the laboratory using the flotation method and the Mac Master one to count coccidia. Weight changes are taken into account as well as mortality in parallel with certain zootechnical parameters such as density. The species of coccidia recovered is Eimeria coturnicis. The results showed that there is an average evolution of mortality of individuals with a rate of 13.33% due to the presence of coccidia with a significant regression (p=0.031). The weight of the quails increases with the age of the animal with a rapid growth rate from the 3rd week onwards. Indeed, the statistical analysis reveals that the evolution of the number did not affect the evolution of the weight (p=0.70) and the GMQ (R=0.52). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coccidiosis" title="coccidiosis">coccidiosis</a>, <a href="https://publications.waset.org/abstracts/search?q=Coturnix%20japonica" title=" Coturnix japonica"> Coturnix japonica</a>, <a href="https://publications.waset.org/abstracts/search?q=daily%20average%20gain" title=" daily average gain"> daily average gain</a>, <a href="https://publications.waset.org/abstracts/search?q=weight" title=" weight"> weight</a> </p> <a href="https://publications.waset.org/abstracts/101063/impact-of-coccidia-on-mortality-and-weight-growth-in-japanese-quail-coturnix-japonica-aves-phasianidae-in-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101063.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">182</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Study of the Toxic Activity of the Entomopathogenic Fungus Beauveria bassiana on the Wistar Rat Rattus norvegicus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Haddadj">F.

This pollution has certainly harmful effects on the environment. In order to reduce the bad effects of these pollutants, many wastewater treatment processes, mainly physicochemical, are implemented. This study consists in using two flocculants; the first one is a biodegradable natural bioflocculant, i.e. Cactaceaeou ficus-indica cactus juice, and the second is the synthetic hydroxyapatite, in a physico-chemical process through coagulation-flocculation, using two coagulants, i.e. ferric chloride and aluminum sulfate, to treat wastewater collected at the entrance of the treatment plant, in the town of Saida. The influence of various experimental parameters, such as the amounts of coagulants and flocculants used, pH, turbidity, COD and BOD5, was investigated. The coagulation - flocculation jar tests of wastewater reveal that ferric chloride, containing a mass of 0.3 g – hydroxyapatite, treated for 1 hour through calcination, is the most effective adjuvant in clarifying the wastewater, with turbidity equal to 98.16 %. In the presence of the two bioflocculants, Cactaceae juice and aluminum sulphate, with a dose of 0.2 g, flocculation is good, with turbidity equal to 95.61 %. Examination of the key reaction parameters, following the flocculation tests of wastewater, shows that the degree of pollution decreases. This is confirmed by the COD and turbidity values obtained. Examination of these results suggests the use of these flocculants in wastewater treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wastewater" title="wastewater">wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=cactus%20ficus-indica" title=" cactus ficus-indica"> cactus ficus-indica</a>, <a href="https://publications.waset.org/abstracts/search?q=hydroxyapatite" title=" hydroxyapatite"> hydroxyapatite</a>, <a href="https://publications.waset.org/abstracts/search?q=coagulation%20-%20flocculation" title=" coagulation - flocculation"> coagulation - flocculation</a> </p> <a href="https://publications.waset.org/abstracts/43194/valorisation-of-a-bioflocculant-and-hydroxyapatites-as-coagulation-flocculation-adjuvants-in-wastewater-treatment-of-the-steppe-in-the-wilaya-of-saida" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43194.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">341</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">11</span> Motivational Profiles of Choice of Medical Studies: Cross-Sectional Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajae%20Tahri">Rajae Tahri</a>, <a href="https://publications.waset.org/abstracts/search?q=Omar%20Chokairi"> Omar Chokairi</a>, <a href="https://publications.waset.org/abstracts/search?q=Asmae%20Saadi"> Asmae Saadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Souad%20Chaouir"> Souad Chaouir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The factors motivating students to choose a medical career is a long-standing topic of publication and discussion. To our knowledge, no national study on the motivation for choosing medical studies has been published to date. Population and methods: This is an observational, descriptive, and cross-sectional study of first-year medical students at the Faculty of Medicine and Pharmacy of Rabat. An anonymous questionnaire comprising 16 questions was developed and distributed to students during Embryology tutorials. The students were free to fill it in or not. The number of students who consented to participate in the survey was 266. The variables studied are the socio-demographic variables of the students and the reasons for choosing medical studies. Results: The most strongly and frequently chosen reasons for choice by our students were saving lives (64.9%), helping others (62.1%), love of medicine (57%), and reducing suffering (56.5%). The comparison of the results according to gender showed a significant difference between the degree of self-motivation of girls compared to that of boys (p <0.001). The reason that stood out the most for them was teamwork. The presence of a health professional in the family was associated with strong extrinsic motivation (p = 0.005). Conclusion: Understanding medical student career choices would improve our knowledge of the factors that influence medical student learning and performance. This knowledge will make it possible to adapt the educational strategies to maintain the motivation of the students throughout their course as well as during their exercise. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=motivation" title="motivation">motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=motivational%20profiles" title=" motivational profiles"> motivational profiles</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20studies" title=" medical studies"> medical studies</a>, <a href="https://publications.waset.org/abstracts/search?q=Morocco" title=" Morocco"> Morocco</a> </p> <a href="https://publications.waset.org/abstracts/161442/motivational-profiles-of-choice-of-medical-studies-cross-sectional-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161442.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">87</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Modelling Interactions between Saturated and Unsaturated Zones by Hydrus 1D, Plain of Kairouan, Central Tunisia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mariem%20Saadi">Mariem Saadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabri%20Kanzari"> Sabri Kanzari</a>, <a href="https://publications.waset.org/abstracts/search?q=Adel%20Zghibi"> Adel Zghibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In semi-arid areas like the Kairouan region, the constant irrigation with saline water and the overuse of groundwater resources, soils and aquifers salinization has become an increasing concern. In this study, a methodology has been developed to evaluate the groundwater contamination risk based on the unsaturated zone hydraulic properties. Two soil profiles with different ranges of salinity, one located in the north of the plain and another one in the south of plain (each 30 m deep) and both characterized by direct recharge of the aquifer were chosen. Simulations were conducted with Hydrus-1D code using measured precipitation data for the period 1998-2003 and calculated evapotranspiration for both chosen profiles. Four combinations of initial conditions of water content and salt concentration were used for the simulation process in order to find the best match between simulated and measured values. The success of the calibration of Hydrus-1D allowed the investigation of some scenarios in order to assess the contamination risk under different natural conditions. The aquifer risk contamination is related to the natural conditions where it increased while facing climate change and temperature increase and decreased in the presence of a clay layer in the unsaturated zone. Hydrus-1D was a useful tool to predict the groundwater level and quality in the case of a direct recharge and in the absence of any information related to the soil layers except for the texture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hydrus-1D" title="Hydrus-1D">Hydrus-1D</a>, <a href="https://publications.waset.org/abstracts/search?q=Kairouan" title=" Kairouan"> Kairouan</a>, <a href="https://publications.waset.org/abstracts/search?q=salinization" title=" salinization"> salinization</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-arid%20region" title=" semi-arid region"> semi-arid region</a>, <a href="https://publications.waset.org/abstracts/search?q=solute%20transport" title=" solute transport"> solute transport</a>, <a href="https://publications.waset.org/abstracts/search?q=unsaturated%20zone" title=" unsaturated zone"> unsaturated zone</a> </p> <a href="https://publications.waset.org/abstracts/71981/modelling-interactions-between-saturated-and-unsaturated-zones-by-hydrus-1d-plain-of-kairouan-central-tunisia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71981.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">183</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">9</span> Japanese Quail Breeding: The Second in Poultry Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Sma%C3%AF">A.

His captive breeding has been practiced for centuries by the Japanese. Knowing that in the literature, it is mentioned that the end of lay is noted for the age of 6 months, our work has revealed a good egg production by females aged up to 35 weeks of age. In the same vein, our study focused on various parameters such as weight, diet and the number of eggs laid and this in order to better know the potential production and reproduction of domestic quail. Egg production has started from the 8th week of age of breeding, crop them and their counts are conducted daily basis until the age of 35 weeks. Indeed, biometric parameters are studied such as weight, length, and the largest diameter, the shape index, the index of shell, in order to analyze the physical condition of eggs by females of age. Until the age of 22 weeks, the eggs have maintained good biometric features. Japanese quail are best producing eggs. Hatchability is also considered. They are excellent poultry yields, since they begin laying eggs in two months and can provide abundant nesting with females over 8 months in our study. Other farms results reveal conclusions. Indeed, one aspect remains to be developed; it is the analysis of nutritional and therapeutic values of eggs over the age of females. The latter, given their wealth is a dietary supplement of animal origin with dietary value (it contains 0 cholesterol) that characterizes the quail eggs. Raising quail among other reproduction requires minimal when compared to other domestic birds space, this is the second breeding, in terms of importance after the chicken. Therefore, in the case of a farm that works exclusively in the production of eggs, requires minimal work and free space, as well as reduced costs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Japanese%20quail" title="Japanese quail">Japanese quail</a>, <a href="https://publications.waset.org/abstracts/search?q=reproduction" title=" reproduction"> reproduction</a>, <a href="https://publications.waset.org/abstracts/search?q=eggs" title=" eggs"> eggs</a>, <a href="https://publications.waset.org/abstracts/search?q=biometrics" title=" biometrics"> biometrics</a>, <a href="https://publications.waset.org/abstracts/search?q=reproductive%20age" title=" reproductive age"> reproductive age</a> </p> <a href="https://publications.waset.org/abstracts/25732/japanese-quail-breeding-the-second-in-poultry-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25732.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">285</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Study of Some Biometric Parameters of the Incubated Eggs and Unhatched Eggs Depending on the Age of Breeding in Domestic Japanese Quail Coturnix japonica (Aves, Phasianidae)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amina%20Sma%C3%AF">Amina Smaï</a>, <a href="https://publications.waset.org/abstracts/search?q=Habiba%20Idouhar-Saadi"> Habiba Idouhar-Saadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Safia%20Zenia"> Safia Zenia</a>, <a href="https://publications.waset.org/abstracts/search?q=Fairouz%20Haddadj"> Fairouz Haddadj</a>, <a href="https://publications.waset.org/abstracts/search?q=Salaheddine%20Doumandji"> Salaheddine Doumandji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The poultry industry (chicken and egg consumption) has become important in Algeria, but that does not prevent other farms from beginning to position themselves on the ground like the turkey, guinea fowl, partridge and quail Japanese. The breeding importance of this last, reside, also in game meat, egg quality and their therapeutic role without forgetting its growth performance. To the same effect, a study was held at the center of Zeralda hunting on various parameters such as the weight and number of eggs laid and this in order to know better the potential of production and reproduction of domestic quail. Egg laying has started from the 8th week of reproductive age, their harvest and their counts are performed daily up to 32 weeks of age and more. We have given the biometrics of incubated eggs and unhatched eggs. The parameters studied were the weight, large and small diameter, density, volume, shell index and the shape index. The work revealed that the maximum weight in males is reached in the 11th week, against the female, he reached the 13th week of age. Indeed, there is a good correlation (R = 0.79) between the weight of females and egg production. The rate of unhatched eggs varies between 11 and 43%, these values are recorded respectively in breeding under the age of 25 and 43 weeks. Furthermore, the biometric parameters of hatched and unhatched eggs have differences that are marked, especially during the beginning and end of lay. Further results will be subsequently exploited. Indeed, rearing Japanese quail is easy in technical terms and does not require big investment but its practical application vigilance and daily presence of the breeder within the farm who oversees the hygiene and well-being of its poultry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Japanese%20quail" title="Japanese quail">Japanese quail</a>, <a href="https://publications.waset.org/abstracts/search?q=biometrics" title=" biometrics"> biometrics</a>, <a href="https://publications.waset.org/abstracts/search?q=eggs" title=" eggs"> eggs</a>, <a href="https://publications.waset.org/abstracts/search?q=unhatching%20eggs" title=" unhatching eggs"> unhatching eggs</a>, <a href="https://publications.waset.org/abstracts/search?q=reproduction" title=" reproduction"> reproduction</a> </p> <a href="https://publications.waset.org/abstracts/46612/study-of-some-biometric-parameters-of-the-incubated-eggs-and-unhatched-eggs-depending-on-the-age-of-breeding-in-domestic-japanese-quail-coturnix-japonica-aves-phasianidae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46612.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">194</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Sudden Death in Young Patients: A Study of 312 Autopsy Cases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Haj%20Salem">N.

Aim: We aim to study the epidemiological characteristics of sudden death in young, and to discuss the mechanism and the importance of autopsy in these situations. Material and methods: We performed a retrospective cohort study using autopsy data from the department of forensic medicine at the University Hospital of Fattouma Bourguiba, Monastir-Tunisia. A review of all autopsies performed during 23 years was done. In each case, clinical information and circumstances of death were obtained. We have included all sudden death in persons aged between 1 year and 35 years for the male and from one year to 45 years for female. We collected 312 cases of sudden death during the studied period. The collected data were processed using SPSS 20. The significance level was set at 0.05. Results: Thirty-two cases of cardiac ischemic sudden death have been collected. Myocardial infarction was the second cause of sudden death in young patients. There was a male predominance. The most affected subjects were aged between 25-45 years. The death occurred more frequently at rest. Coronary artery disease has been discovered in twenty-four cases (75%). A severe coronary artery disease was observed in two children with medical history of familial hypercholesterolemia. The myocardial infarction occurred in healthy coronary arteries in eight cases. An anomalous course of coronary arteries, in particular, myocardial bridging, was found in eight cases (25%). Toxicological screening was negative in all cases. Second cause of death was hypertrophic cardiomyopathy. Neurological and respiratory causes of death were implicated respectively in 10% and 15%. Conclusion: Identifying epidemiological characteristics of sudden death in this population is important for guiding approaches to prevention that must be based on dietary hygienic measures and the control of cardiovascular risk factors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autopsy" title="autopsy">autopsy</a>, <a
