Entomopathogenic microorganisms occupy an important place among the alternative methods of fighting against pests insect. The fungus Beauveria bassiana is an entomopathogenic agent naturally present in the ecosystems. It offers a very interesting potential for controlling populations of mosquitoes. This study aimed to show the histological changes that occured in Culex pipiens larvae infected with Beauveria bassiana. The 4th instar larvae were infected with B. bassiana in 10-7 spore/ml dilution, the histological section was studied showing that the fungi infected all the body parts specially Cuticle, Epiderms, fat bodies and midgut. After then the insect have a white appearance and covered with a thick coat of hyphea. The obtained results show that the application of Beauveria bassiana on cuticle of the fourth stage larvae of Culex pipiens was dependent of an apparent disturbance on the structure of the cuticle or there has been the degeneration of its different parts, infection of the fungus does not stop at the body walls. Therefore, it affects even the Adipose tissue, epidermal cells and intestine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Culex%20pipiens" title="Culex pipiens">Culex pipiens</a>, <a href="https://publications.waset.org/abstracts/search?q=Beauveria%20bassiana" title=" Beauveria bassiana"> Beauveria bassiana</a>, <a href="https://publications.waset.org/abstracts/search?q=histological%20changes" title=" histological changes"> histological changes</a>, <a href="https://publications.waset.org/abstracts/search?q=cuticle" title=" cuticle"> cuticle</a>, <a href="https://publications.waset.org/abstracts/search?q=intestine%20and%20adipose%20tissue" title=" intestine and adipose tissue "> intestine and adipose tissue </a> </p> <a href="https://publications.waset.org/abstracts/12650/histological-changes-in-the-culex-pipiens-mosquito-larvae-treated-by-the-entomopathogenic-fungus-beauveria-bassiana" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12650.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">281</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">118</span> An Analysis of Methodological Approaches of Ahmed Cevdet and Fatma Aliye towards the Ottoman Historiography in a Comparative Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aysen%20Muderrisoglu%20Esiner">Aysen Muderrisoglu Esiner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As an intellectual, scholar, bureaucrat, and statesman, Ahmed Cevdet Pasha (1822-1895) was the prominent figure of “Tanzimat” (reorganization) reforms of the Ottoman State while his daughter Fatma Aliye (1862-1936) was a novelist, columnist, essayist, and women’s rights activist. His father had numerous books on law, grammar, linguistics, logic, and astronomy, moreover, Aliye accepted as the first female novelist in the Turkish literature and the Islamic world. Even if she was better known as a novelist, she also published some works on philosophy, Islam, poetry. In addition, Aliye who was one of the pioneers of the Ottoman women’s movement, also wrote historical works. Her historical works which titled as Tarih-i Osmaninin Bir Devre-i Mühimmesi Kosova Zaferi-Ankara Hezimeti (An Important Era of the Ottoman History: Kosova Victory-Ankara Defeat), and Ahmed Cevdet Paşa ve Zamanı (Ahmed Cevdet Pasha and His Time) have been generally ignored in the literature. However, Aliye’s works in history field are worth being studied in terms of her methodological approach to the Ottoman historiography. On the other hand, written by Ahmed Cevdet Pasha, such as Tarih-i Cevdet (History of Cevdet), Tezâkir (Memoir), Mâruzat (Reports, the events that took place between 1839-1876, 1890), Kısas-ı Enbiya ve Tevârîh-i Hulefa (Retaliation of the Prophets and the History of Calips), Kırım ve Kafkas Tarihçesi (Crimean and Caucasian History) are the most important works in terms of historiography in the 19th century. In contrast to the traditional methodology, Cevdet Pasha brought a new understanding to the Ottoman historiography by making a synthesis between the traditional and modern methods. In this research, the historical works of these two prominent figures of the Ottoman State will be analyzed in terms of their approaches to the Ottoman historiography while evaluating the following questions: to what extent that their use of local and foreign historical sources and their handling of the historical events differ, or if it is possible to talk about a methodological similarities in terms of historiography. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Cevdet%20Pasha" title="Ahmed Cevdet Pasha">Ahmed Cevdet Pasha</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Aliye" title=" Fatma Aliye"> Fatma Aliye</a>, <a href="https://publications.waset.org/abstracts/search?q=historiography" title=" historiography"> historiography</a>, <a href="https://publications.waset.org/abstracts/search?q=methodology" title=" methodology"> methodology</a> </p> <a href="https://publications.waset.org/abstracts/129590/an-analysis-of-methodological-approaches-of-ahmed-cevdet-and-fatma-aliye-towards-the-ottoman-historiography-in-a-comparative-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129590.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">257</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">117</span> Microbiota Effect with Cytokine in Hl and NHL Patient Group</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ekin%20Ece%20G%C3%BCrer">Ekin Ece Gürer</a>, <a href="https://publications.waset.org/abstracts/search?q=Tar%C4%B1k%20Onur%20Tiryaki"> Tarık Onur Tiryaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Sevgi%20Kalayo%C4%9Flu%20Be%C5%9F%C4%B1%C5%9F%C4%B1k"> Sevgi Kalayoğlu Beşışık</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Savran%20O%C4%9Fuz"> Fatma Savran Oğuz</a>, <a href="https://publications.waset.org/abstracts/search?q=U%C4%9Fur%20Sezerman"> Uğur Sezerman</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Erdem"> Fatma Erdem</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%BCl%C5%9Fen%20G%C3%BCnel"> Gülşen Günel</a>, <a href="https://publications.waset.org/abstracts/search?q=D%C3%BCrdane%20Serap%20Kuruca"> Dürdane Serap Kuruca</a>, <a href="https://publications.waset.org/abstracts/search?q=Zerrin%20Akta%C5%9F"> Zerrin Aktaş</a>, <a href="https://publications.waset.org/abstracts/search?q=Oral%20%C3%96nc%C3%BCl"> Oral Öncül</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim: Chemotherapytreatment in HodgkinLymphomaandNon-HodgkinLymphoma (NHL) diseasescausesgastrointestinalepithelialdamage, disruptstheintestinalmicrobiotabalanceandcausesdysbiosis.

The TAM represents an important theoretical contribution toward understanding how users come to accept and use technology. This model suggests that when people are presented with a new technology, a number of variables influence their decision about how and when they will use it. The results showed that participants accept more technology because flexibility, clarity, enhancing the experience, enjoying, facility, and useful.

Photovoltaic generators (GPV) can deliver maximum power for a point on the characteristic P = f (Vpv), called maximum power point (MPP), or climatic variations, entraiment fluctuation PPM. To remedy this problem is interposed between the generator and receiver a DC-DC converter. The converter is usually used a simple MOSFET chopper. However, the MOSFET can be applied in the field of low power when you need a high switching frequency but becomes highly dissipative when should block large voltages For PV generators medium and high power, the use of IGBT chopper is by far the most recommended. To reduce stress on semiconductor components using several choppers series connected in parallel is known as interleaved chopper. These choppers lead to rotas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=converter%20DC-DC%20entrelaced%01%02%01" title="converter DC-DC entrelaced">converter DC-DC entrelaced</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20generators" title=" photovoltaic generators"> photovoltaic generators</a>, <a href="https://publications.waset.org/abstracts/search?q=IGBT" title=" IGBT"> IGBT</a>, <a href="https://publications.waset.org/abstracts/search?q=optimisation" title=" optimisation"> optimisation</a> </p> <a href="https://publications.waset.org/abstracts/21869/optimisation-of-photovoltaic-array-with-dc-dc-converter-groups" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21869.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">539</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">100</span> Tracing the Concept of Equivalence in Translation Theories from the Linguistics Oriented Era to Present </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatma%20%C3%9Clk%C3%BC%20Kavruk">Fatma Ülkü Kavruk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The comparison of the old and new approaches reveals that the concept of equivalence has been interpreted and categorized in different ways by different scholars throughout the history.

In this paper, we propose a novel extension to this method. Firstly, we extract features in multi-scales by applying a color local descriptor named opponent-SIFT. Secondly, in order to represent image we use Spatial Pyramid Representation (SPR) and an extension to the BOW method which based on weighting visual words. Typically, the visual words are weighted during histogram assignment by computing the ratio of their occurrences in the image to the occurrences in the background. Finally, according to classical BOW retrieval framework, only a few words of the vocabulary is useful for image representation. Therefore, we select the useful weighted visual words that respect the threshold value. Experimentally, the algorithm is tested by using different image classes of PASCAL VOC 2007 and is compared against the classical bag-of-visual-words algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BOW" title="BOW">BOW</a>, <a href="https://publications.waset.org/abstracts/search?q=useful%20visual%20words" title=" useful visual words"> useful visual words</a>, <a href="https://publications.waset.org/abstracts/search?q=weighted%20visual%20words" title=" weighted visual words"> weighted visual words</a>, <a href="https://publications.waset.org/abstracts/search?q=bag%20of%20visual%20words" title=" bag of visual words"> bag of visual words</a> </p> <a href="https://publications.waset.org/abstracts/14009/bag-of-words-representation-based-on-weighting-useful-visual-words" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14009.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">436</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">97</span> A Secure Proxy Signature Scheme with Fault Tolerance Based on RSA System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20El-Kamchouchi">H.

The results revealed that the quality of all the investigated water sources are generally at satisfactory level as surface water except for Pazar Stream in terms of ortho-phosphate and BOD5 concentration for 2008. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kurtbogazi%20dam" title="Kurtbogazi dam">Kurtbogazi dam</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality%20assessment" title=" water quality assessment"> water quality assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=Ankara%20water" title=" Ankara water"> Ankara water</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20supply" title=" water supply"> water supply</a> </p> <a href="https://publications.waset.org/abstracts/34379/evaluation-of-water-quality-for-the-kurtbogazi-dam-outlet-and-the-streams-feeding-the-dam-ankara-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34379.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">377</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">92</span> Determination of Weathering at Kilistra Ancient City by Using Non-Destructive Techniques, Central Anatolia, Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C4%B0smail%20%C4%B0nce">İsmail İnce</a>, <a href="https://publications.waset.org/abstracts/search?q=Osman%20G%C3%BCnaydin"> Osman Günaydin</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20%C3%96zer"> Fatma Özer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stones used in the construction of historical structures are exposed to various direct or indirect atmospheric effects depending on climatic conditions. Building stones deteriorate partially or fully as a result of this exposure. The historic structures are important symbols of any cultural heritage. Therefore, it is important to protect and restore these historical structures. The aim of this study is to determine the weathering conditions at the Kilistra ancient city. It is located in the southwest of the Konya city, Central Anatolia, and was built by carving into pyroclastic rocks during the Byzantine Era. For this purpose, the petrographic and mechanical properties of the pyroclastic rocks were determined. In the assessment of weathering of structures in the ancient city, in-situ non-destructive testing (i.e., Schmidt hardness rebound value, relative humidity measurement) methods were applied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultural%20heritage" title="cultural heritage">cultural heritage</a>, <a href="https://publications.waset.org/abstracts/search?q=Kilistra%20ancient%20city" title=" Kilistra ancient city"> Kilistra ancient city</a>, <a href="https://publications.waset.org/abstracts/search?q=non-destructive%20techniques" title=" non-destructive techniques"> non-destructive techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=weathering" title=" weathering"> weathering</a> </p> <a href="https://publications.waset.org/abstracts/63339/determination-of-weathering-at-kilistra-ancient-city-by-using-non-destructive-techniques-central-anatolia-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63339.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">359</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">91</span> Corporate Societal Disclosure and Corporate Governance: A By-Contextual Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zineb%20Meniaoui">Zineb Meniaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Zehri"> Fatma Zehri</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamoussi%20Halioui"> Kamoussi Halioui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The amplified awareness of companies towards the social and environmental concerns has nowadays become a challenge for firms around the globe. Our study investigates the effects of corporate governance mechanisms on voluntarily social and environmental information disclosure in Canada and France. The study use the content analysis approach, applied on a total of 245 year-observation for the Canadian sample and 245 year-observation for the French sample from 2005 to 2011. Our results show a significant correlation between the board's independence, Corporate Social Responsibility (CSR) committee and expertise as well as the audit quality along with the extent of the social and environmental disclosure. The French firms are found disclosing more societal information than Canadian firms, which might be due to the stakeholders' pressure put on French companies to disclose such societal information. <p
