Mozduran Formation in the east of Kopet-Dagh is mainly composed of limestone, dolomite, with shale and sandstone interbedded. Mozduran Formation is reservoir rock of the Khangiran gas field. The location of the study was east Kopet-Dagh basin (Northeast Iran) where the deliberate thickness of formation is 418 meters. In the present study, a total of 57 samples were gathered. Moreover, 100 thin sections were made out of 52 samples. According to the findings of the thin section study, 18 genera and nine species of foraminifera and algae were identified. Based on the index fossils, the age of the Mozduran Formation was identified as Upper Jurassic (Kimmerdgian-Tithonian) in the east of Kopet-Dagh basin. According to the magnetite data (total intensity and RTP map), there is a disconformity (low intensity) between the Kashaf-Rood Formation and Mozduran Formation. At the top, where among Mozduran Formation and Shurijeh Formation, is high intensity and a widespread disconformity (high intensity). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=upper%20jurassic" title="upper jurassic">upper jurassic</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetometre" title=" magnetometre"> magnetometre</a>, <a href="https://publications.waset.org/abstracts/search?q=mozduran%20formation" title=" mozduran formation"> mozduran formation</a>, <a href="https://publications.waset.org/abstracts/search?q=stratigraphy" title=" stratigraphy"> stratigraphy</a> </p> <a href="https://publications.waset.org/abstracts/64008/stratigraghy-and-identifying-boundaries-of-mozduran-formation-with-magnetite-method-in-east-kopet-dagh-basin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64008.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">225</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">5314</span> Enthalpies of Formation of Equiatomic Binary Hafnium Transition Metal Compounds HfM (M=Co, Ir, Os, Pt, Rh, Ru)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hadda%20Krarcha">Hadda Krarcha</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Messaasdi"> S.

It is a question of exceeding the traditional approaches focused on morphosyntactic approaches. Furthermore, we present a new approach that analyze a text in order to extract correct answers then transform it to logical predicates. In addition, we would like to represent different levels of information within a text to answer a question and choose an answer among several proposed. To do so, we transform both the question and the text into logical forms. Then, we try to recognize all entailment between them. The results of recognizing the entailment are a set of text sentences that can implicate the user’s question. Our work is now concentrated on an implementation step in order to develop a system of question-answering in Arabic using techniques to recognize textual implications. In this context, the extraction of text features (keywords, named entities, and relationships that link them) is actually considered the first step in our process of text modeling. The second one is the use of techniques of textual implication that relies on the notion of inference and logic representation to extract candidate answers. The last step is the extraction and selection of the desired answer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NLP" title="NLP">NLP</a>, <a href="https://publications.waset.org/abstracts/search?q=Arabic%20language" title=" Arabic language"> Arabic language</a>, <a href="https://publications.waset.org/abstracts/search?q=question-answering" title=" question-answering"> question-answering</a>, <a href="https://publications.waset.org/abstracts/search?q=recognition%20text%20entailment" title=" recognition text entailment"> recognition text entailment</a>, <a href="https://publications.waset.org/abstracts/search?q=logic%20forms" title=" logic forms"> logic forms</a> </p> <a href="https://publications.waset.org/abstracts/27265/towards-logical-inference-for-the-arabic-question-answering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27265.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">343</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">5312</span> Leveraging Unannotated Data to Improve Question Answering for French Contract Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Touila%20Ahmed">Touila Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Elie%20Louis"> Elie Louis</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamza%20Gharbi"> Hamza Gharbi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> State of the art question answering models have recently shown impressive performance especially in a zero-shot setting.

In this article we want to discuss these with a special focus on mathematics education. The intention is to make neuroscience research useful for the description of cognitive mathematical learning processes. A key issue of mathematics education is that students often behave as if their mathematical knowledge is constructed in isolated compartments with respect to the specific context of the original learning situation; supporting students to link these compartments to form a coherent mathematical society of mind is a fundamental task not only for mathematics teachers. This aspect goes hand in hand with the question if there is such a thing as abstract general mathematical knowledge detached from concrete reality. Educational Neuroscience may give answers to the question why students develop their mathematical knowledge in isolated subjective domains of experience and if it is generally possible to think in abstract terms. To address these questions, we will provide examples from different fields of mathematics education e.g. students’ development and understanding of the general concept of variables or the mathematical notion of universal proofs. We want to discuss these aspects in the reflection of functional studies which elucidate the role of specific brain regions in mathematical learning processes. In doing this the paper addresses concept formation processes of students in the mathematics classroom and how to support them adequately considering the results of (educational) neuroscience. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brain%20regions" title="brain regions">brain regions</a>, <a href="https://publications.waset.org/abstracts/search?q=concept%20formation%20processes%20in%20mathematics%20education" title=" concept formation processes in mathematics education"> concept formation processes in mathematics education</a>, <a href="https://publications.waset.org/abstracts/search?q=proofs" title=" proofs"> proofs</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching-learning%20processes" title=" teaching-learning processes"> teaching-learning processes</a> </p> <a href="https://publications.waset.org/abstracts/126498/brain-networks-and-mathematical-learning-processes-of-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126498.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">149</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">5310</span> Geochemical Characterization of the Fahdene Formation in the Kef-Tedjerouine Area (Northwestern Tunisia)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tahani%20Hallek">Tahani Hallek</a>, <a href="https://publications.waset.org/abstracts/search?q=Dhaou%20Akrout"> Dhaou Akrout</a>, <a href="https://publications.waset.org/abstracts/search?q=Riadh%20Ahmadi"> Riadh Ahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mabrouk%20Montacer"> Mabrouk Montacer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present work is an organo-geochemical study of the Fahdene Formation outcrops at the Mahjouba region belonging to the Eastern part of the Kalaat Senan structure in northwestern Tunisia (the Kef-Tedjerouine area). The analytical study of the organic content of the samples collected, allowed us to point out that the Formation in question is characterized by an average to good oil potential. This fossilized organic matter has a planktonic marine origin (type II), as indicated by the relatively high values of hydrogen index. Tmax values are in the range 440°C and attest a thermal stage of the oil window beginning. Mineralogical study found the existence of macro and micro fractures that are parallel to rock stratification or oblique with a high density. Fill standpoint, the major component of the mineralized veins is the fibrous calcite with bitumen traces. The composition of these fractures is mainly due to the availability of chemical elements scattered in the surrounding rock. As for the origin of these fractures, we assume that fluid pressure processes are heavily involved, together with the regional compressional tectonic stress regime. The Fahdene Formation has a great importance in conventional oil development as a potential source rock, and even in terms of unconventional oil exploitation through the intense fracturing allowing the percolation of gas shale and facilitating its exploitation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fluid%20pressure" title="fluid pressure">fluid pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=fracturation" title=" fracturation"> fracturation</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20exploration" title=" oil exploration"> oil exploration</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20matter" title=" organic matter"> organic matter</a> </p> <a href="https://publications.waset.org/abstracts/47545/geochemical-characterization-of-the-fahdene-formation-in-the-kef-tedjerouine-area-northwestern-tunisia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47545.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">259</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">5309</span> An Empirical Analysis of the Impact of Selected Macroeconomic Variables on Capital Formation in Libya (1970–2010)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Ramadan%20Elbeydi">Khaled Ramadan Elbeydi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is carried out to provide an insight into the analysis of the impact of selected macro-economic variables on gross fixed capital formation in Libya using annual data over the period (1970-2010). The importance of this study comes from the ability to show the relative important factors that impact the Libyan gross fixed capital formation. This understanding would give indications to decision makers on which policy they must focus to stimulate the economy. An Auto-Regressive Distributed Lag (ARDL) modeling process is employed to investigate the impact of the gross domestic product, monetary base, and trade openness on gross fixed capital formation in Libya. The results of this study reveal that there is an equilibrium relationship between capital formation and its determinants. The results also indicate that GDP and trade openness largely explain the pattern of capital formation in Libya. The findings and recommendations provide vital information relevant for policy formulation and implementation aimed to improve capital formation in Libya. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ARDL" title="ARDL">ARDL</a>, <a href="https://publications.waset.org/abstracts/search?q=bounds%20test" title=" bounds test"> bounds test</a>, <a href="https://publications.waset.org/abstracts/search?q=capital%20formation" title=" capital formation"> capital formation</a>, <a href="https://publications.waset.org/abstracts/search?q=co-integration" title=" co-integration"> co-integration</a>, <a href="https://publications.waset.org/abstracts/search?q=Libya" title=" Libya"> Libya</a> </p> <a href="https://publications.waset.org/abstracts/4764/an-empirical-analysis-of-the-impact-of-selected-macroeconomic-variables-on-capital-formation-in-libya-1970-2010" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4764.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">5308</span> Determination of Biofilm Formation in Different Clinical Candida Species and Investigation of Effects of Some Plant Substances on These Biofilms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gulcan%20Sahal">Gulcan Sahal</a>, <a href="https://publications.waset.org/abstracts/search?q=Isil%20Seyis%20Bilkay"> Isil Seyis Bilkay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Candida species which often exist as commensal microorganisms in healthy individuals are major causes of important infections, especially in AIDS and immunocompromised patients, by means of their biofilm formation abilities. Therefore, in this study, determination of biofilm formation in different clinical strains of Candida species, investigation of strong biofilm forming Candida strains, examination of clinical information of each strong and weak biofilm forming Candida strains and investigation of some plant substances’ effects on biofilm formation of strong biofilm forming strains were aimed. In this respect, biofilm formation of Candida strains was analyzed via crystal violet binding assay. According to our results, biofilm levels of strains belong to different Candida species were different from each other. Additionally, it is also found that some plant substances effect biofilm formation. All these results indicate that, as well as C. albicans strains, other non-albicans Candida species also emerge as causative agents of infections and have biofilm formation abilities. In addition, usage of some plant substances in different concentrations may provide a new treatment against biofilm related Candida infections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-biofilm" title="anti-biofilm">anti-biofilm</a>, <a href="https://publications.waset.org/abstracts/search?q=biofilm%20formation" title=" biofilm formation"> biofilm formation</a>, <a href="https://publications.waset.org/abstracts/search?q=Candida%20species" title=" Candida species"> Candida species</a>, <a href="https://publications.waset.org/abstracts/search?q=biosystems%20engineering" title=" biosystems engineering"> biosystems engineering</a> </p> <a href="https://publications.waset.org/abstracts/8322/determination-of-biofilm-formation-in-different-clinical-candida-species-and-investigation-of-effects-of-some-plant-substances-on-these-biofilms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8322.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">484</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">5307</span> The Functions of “Question” and Its Role in Education Process: Quranic Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Tusian">Sara Tusian</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Salehi%20Motaahed"> Zahra Salehi Motaahed</a>, <a href="https://publications.waset.org/abstracts/search?q=Narges%20Sajjadie"> Narges Sajjadie</a>, <a href="https://publications.waset.org/abstracts/search?q=Nikoo%20Dialame"> Nikoo Dialame</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the methods which have frequently been used in Quran is the “question”. In the Quran, in addition to the content, methods are also important. Using analysis-interpretation method, the present study has investigated Quranic questions, and extracted its functions from educational perspective. In so doing, it has first investigated all the questions in Quran and then taking the three-stage classification of education into account, it has offered question functions. The results obtained from this study suggest that question functions in Quran are presented in three categories: the preparation stage (including preparation of the audience, revising the insights, and internal Evolution); main body (including the granting the insight, and elimination of intellectual negligence and the question of innate and logical axioms, the introducting of the realm of thinking, creating emotional arousal and alleged in the claim) and the third stage as modification and revision (including invitation to move in the framework of tasks using the individual beliefs to reveal the contradictions and, Error detection and contribution to change the function) that each of which has a special role in the education process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=education" title="education">education</a>, <a href="https://publications.waset.org/abstracts/search?q=question" title=" question"> question</a>, <a href="https://publications.waset.org/abstracts/search?q=Quranic%20questions" title=" Quranic questions"> Quranic questions</a>, <a href="https://publications.waset.org/abstracts/search?q=Quran" title=" Quran"> Quran</a> </p> <a href="https://publications.waset.org/abstracts/18361/the-functions-of-question-and-its-role-in-education-process-quranic-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18361.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">503</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">5306</span> Biofilm Formation Due to the Proteome Changes Of Enterococcus Faecium in Response to Sub-Mic of Gentamicin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amin%20Abbasi">Amin Abbasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Asghari%20Ozma"> Mahdi Asghari Ozma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Objective:Enterococcus faecium is a normal flora of the human gastrointestinal tract that causes infection in the host body under conditions such as biofilm formation, in which the use of antibiotics causes changes in these pathogenic mechanisms. In this study, we aimed to evaluate comprehensively the changes in E.faecium when exposed to sub-MIC of the gentamicin,especiallythe biofilm formation rate. Materials and Methods: For this study, the keywords "Enterococcus faecium ", "Biofilm", and "Gentamicin" in the databases PubMed, Google Scholar, Sid, and MagIran between 2015 and 2021 were searched, and 14 articles were chosen, studied, and analyzed. Results: Gentamicin significantly had increased biofilm formation in most of the isolates in the studies. Increased expression of the genes (efaA and esp) and proteins involved in biofilm formation and decreased expression of the genes (gelE and cylA) involved in spreading and proteins involved in metabolism and cell division in E.faecium were the most significant cause of the biofilm formation, which were increased in sub-MIC gentamicin-treated situation. Conclusion: Inadequate use of gentamicin intensify biofilm formation of E.faecium, which can make the treatment of infections caused by this bacterium difficult. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biofilm" title="biofilm">biofilm</a>, <a href="https://publications.waset.org/abstracts/search?q=enterococcus%20faecium" title=" enterococcus faecium"> enterococcus faecium</a>, <a href="https://publications.waset.org/abstracts/search?q=gentamicin" title=" gentamicin"> gentamicin</a>, <a href="https://publications.waset.org/abstracts/search?q=proteome" title=" proteome"> proteome</a> </p> <a href="https://publications.waset.org/abstracts/150995/biofilm-formation-due-to-the-proteome-changes-of-enterococcus-faecium-in-response-to-sub-mic-of-gentamicin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150995.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">111</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">5305</span> The Evolution of the Simulated and Observed Star Formation Rates of Galaxies for the Past 13 Billion Years</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antonios%20Katsianis">Antonios Katsianis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> I present the evolution of the galaxy Star Formation Rate Function (SFRF), star formation rate-stellar mass relation (SFR-M*) and Cosmic Star Formation Rate Density (CSFRD) of z = 0-8 galaxies employing both the Evolution and Assembly of GaLaxies and their Environments (EAGLE) simulations and a compilation of UV, Ha, radio and IR data.

I present the evolution of the SFR-M* relation and demonstrate the inconsistencies between observations that are retrieved using different methods. I employ cosmological hydrodynamic simulations combined with radiative transfer methods and compare these with a range of observed data in order to investigate further the root of this tension.

Our underlying model is an overlapping generation model (OLG) with some degree of altruism on the part of the ancestors' generation towards their descendants. We ask the question in three separate frameworks. First, we study a simple one-sector model where a proxy of human capital is wage income. It the steady-state -for CRRA utility function and human capital produced with non-decreasing returns -the taxation of bequests is neutral to the accumulation of human capital. In the second framework, neutrality applies to the growth rates of human capital, physical capital, and consumption. In this case, taxation increases the level of bequests, leading to a lower value of current consumption. Finally in we consider two periods model instead of infinite horizon model as long as the tax revenue is at least partially rebated back to the public, the fraction of human capital engaged in the process of formation of human capital increases with the tax rate on bequests. In other words, taxation of bequests is partially offset by an increase in human capital formation. Higher human capital allows the future generation to earn higher wages, and today's generation can find it optimal to endow the future generation with more human capital when taxation is imposed on physical capital transferred to the next generation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=taxation" title="taxation">taxation</a>, <a href="https://publications.waset.org/abstracts/search?q=bequests" title=" bequests"> bequests</a>, <a href="https://publications.waset.org/abstracts/search?q=policy" title=" policy"> policy</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20capital" title=" human capital"> human capital</a> </p> <a href="https://publications.waset.org/abstracts/122668/the-impact-of-bequest-taxation-on-human-capital-accumulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122668.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">168</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">5303</span> Determination of Lithology, Porosity and Water Saturation for Mishrif Carbonate Formation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20S.%20Kadhim">F.

The accurate calculations of porosity in carbonate reservoirs are the most challenging aspects of well log analysis. Many equations have been developed over the years based on known physical principles or on empirically derived relationships, which are used to calculate porosity, estimate lithology and water saturation; however these parameters are calculated from well logs by using modern technique in a current study. Nasiriya (NS) oilfield is one of giant oilfields in the Middle East, and the formation under study is the Mishrif carbonate formation which is the shallowest hydrocarbon bearing zone in the NS oilfield. Neurolog software (V5, 2008) was used to digitize the scanned copies of the available logs. Environmental corrections had been made as per Schlumberger charts 2005, which supplied in the Interactive Petrophysics software (IP, V3.5, 2008). Three saturation models have been used to calculate water saturation of carbonate formations, which are simple Archie equation, Dual water model, and Indonesia model. Results indicate that the Mishrif formation consists mainly of limestone, some dolomite and shale. The porosity interpretation shows that the logging tools have a good quality after making the environmental corrections. The average formation water saturation for Mishrif formation is around 0.4-0.6.This study is provided accurate behavior of petrophysical properties with depth for this formation by using modern software. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lithology" title="lithology">lithology</a>, <a href="https://publications.waset.org/abstracts/search?q=porosity" title=" porosity"> porosity</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20saturation" title=" water saturation"> water saturation</a>, <a href="https://publications.waset.org/abstracts/search?q=carbonate%20formation" title=" carbonate formation"> carbonate formation</a>, <a href="https://publications.waset.org/abstracts/search?q=mishrif%20formation" title=" mishrif formation"> mishrif formation</a> </p> <a href="https://publications.waset.org/abstracts/27926/determination-of-lithology-porosity-and-water-saturation-for-mishrif-carbonate-formation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27926.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">373</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">5302</span> Early Formation of Adipocere in Subtropical Climate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asit%20K.%20Sikary">Asit K.

It consists mainly of saturated fatty acids, formed by the post-mortem hydrolysis and hydrogenation of body fats with the help of bacterial enzymes in the presence of warmth, moisture and anaerobic bacteria. In temperate climate, it takes weeks to develop while in India it starts to begin within 4-5 days. In this study, we have collected cases with adipocere formation, which were from the South Delhi region (average room temperature 27-390C) and autopsied at our centre. Details of the circumstances of the death, cause and time of death, surrounding environment and demographic profile of the deceased were taken into account. Total 16 cases were included in this study. Adipocere formation was predominantly present over cheeks, shoulder, breast, flanks, buttocks, and thighs. Out of 16, 11 cases were found in a dry atmosphere, 5 cases were brought from the water. There were 5 cases in which adipocere formation was seen in less than 2 days, and among them, in 1 case, as early as one day. This study showed that adipocere formation can be seen as early as 1 day in a hot and humid environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adipocere" title="adipocere">adipocere</a>, <a href="https://publications.waset.org/abstracts/search?q=drowning" title=" drowning"> drowning</a>, <a href="https://publications.waset.org/abstracts/search?q=hanging" title=" hanging"> hanging</a>, <a href="https://publications.waset.org/abstracts/search?q=humid%20environment" title=" humid environment"> humid environment</a>, <a href="https://publications.waset.org/abstracts/search?q=strangulation" title=" strangulation"> strangulation</a>, <a href="https://publications.waset.org/abstracts/search?q=subtropical%20climate" title=" subtropical climate"> subtropical climate</a> </p> <a href="https://publications.waset.org/abstracts/27971/early-formation-of-adipocere-in-subtropical-climate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27971.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">422</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">5301</span> Expressivity of Word-Formation in English and Russian Advertising Lexicon</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Voronina%20Ekaterina%20Borisovna">Voronina Ekaterina Borisovna</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The problem of expressivity of advertising lexicon is studied in the article.

The hydrocolloid coatings significantly reduced acrylamide formation in potatoes fried in all oils. Increasing the hydrocolloid concentration from 0.3% to 0.7% produced no effective inhibition of acrylamide. The 0.7 % CMC solution was identified as the most promising inhibitor of acrylamide formation in RCO oil, with a 62.9% reduction in acrylamide content. The addition of BKO or USM to RCO led to a noticeable reduction in the acrylamide level in fried potato slices.

The primary goal of this research is to diagnose the paleoenvironment, petrographic compositions, and sedimentary sources of the Hong Hoi Formation in Ban Huat, Ngao District. The Triassic Hong Hoi Formation is chosen because the outcrops are continuous and fossils are greatly exposed and abundant. Depositional environment is reconstructed through sedimentological studies along with facies analysis. The Hong Hoi Formation is petrographically divided into two major facies, they are: sandstones with mudstone interbeds, and mudstones or shale with sandstone interbeds. Sandstone beds are lithic arenite and lithic greywacke, volcanic lithic fragments are dominated. Sedimentary structures, paleocurrent data and lithofacies arrangement indicate that the formation deposited in a part of deep marine abyssal plain environment. The sedimentological and petrographic features suggest that during the deposition the Hong Hoi Formation received sediment supply from nearby volcanic arc. This suggested that the intensive volcanic activity within the Sukhothai Arc during the Middle Triassic is the main sediment source. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sukhothai%20zone" title="Sukhothai zone">Sukhothai zone</a>, <a href="https://publications.waset.org/abstracts/search?q=petrography" title=" petrography"> petrography</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Hoi%20formation" title=" Hong Hoi formation"> Hong Hoi formation</a>, <a href="https://publications.waset.org/abstracts/search?q=Lampang" title=" Lampang"> Lampang</a>, <a href="https://publications.waset.org/abstracts/search?q=Triassic" title=" Triassic"> Triassic</a> </p> <a href="https://publications.waset.org/abstracts/111476/sedimentological-study-of-bivalve-fossils-site-locality-in-hong-hoi-formation-in-lampang-thailand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111476.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">213</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">5298</span> Investigation of Biofilm Formation in Clinical Strains of Klebsiella pneumoniae and Klebsiella rhinoscleromatis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gulcan%20Sahal">Gulcan Sahal</a>, <a href="https://publications.waset.org/abstracts/search?q=Nermin%20Hande%20Avcioglu"> Nermin Hande Avcioglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Isil%20Seyis%20Bilkay"> Isil Seyis Bilkay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Klebsiella species which are natural colonizers of human upper respiratory and human gastrointestinal tracts are also responsible for every reoccurring nosocomial infections by means of having ability to form slimy layers known as biofilm on many surfaces. Therefore, in this study, investigation of biofilm formation in K. pneumoniae and K. rhinoscleromatis and examination of each Klebsiella strains’ clinical information in the light of their biofilm formation results were aimed. In this respect, biofilm formation of Klebsiella strains was analyzed via crystal violet binding assay. According to our results, biofilm formation levels of K. pneumoniae and K. rhinoscleromatis strains were different from each other. Additionally, in comparison to K. rhinoscleromatis strains, K. pneumoniae was observed to include higher amounts of strong biofilm forming strains. Besides, it was also seen that clinical information of patients from which strong biofilm forming Klebsiella strains were isolated were similar to each other. Our results indicate that there should be more precautions against K. pneumoniae which includes higher amount of strong biofilm forming strains. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biofilm%20formation" title="biofilm formation">biofilm formation</a>, <a href="https://publications.waset.org/abstracts/search?q=Klebsiella%20pneumoniae" title=" Klebsiella pneumoniae"> Klebsiella pneumoniae</a>, <a href="https://publications.waset.org/abstracts/search?q=Klebsiella%20rhinoscleromatis" title=" Klebsiella rhinoscleromatis"> Klebsiella rhinoscleromatis</a>, <a href="https://publications.waset.org/abstracts/search?q=biosystems%20engineering" title=" biosystems engineering"> biosystems engineering</a> </p> <a href="https://publications.waset.org/abstracts/8310/investigation-of-biofilm-formation-in-clinical-strains-of-klebsiella-pneumoniae-and-klebsiella-rhinoscleromatis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8310.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">390</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">5297</span> An Expert System for Assessment of Learning Outcomes for ABET Accreditation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20H.%20Imam">M.

A question in an assessment must target a CLO as well as an SO and must represent a required level of competence. This paper presents the idea of an Expert System (ES) to select a proper question to satisfy ABET accreditation requirements. For ES implementation, seven attributes of a question are considered including the learning outcomes and Bloom’s Taxonomy level. A database contains all the data about a course including course content topics, course learning outcomes and the CLO-SO relationship matrix. The knowledge base of the presented ES contains a pool of questions each with tags of the specified attributes. Questions and the attributes represent expert opinions. With implicit rule base the inference engine finds the best possible question satisfying the required attributes. It is shown that the novel idea of such an ES can be implemented and applied to a course with success. An application example is presented to demonstrate the working of the proposed ES. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=expert%20system" title="expert system">expert system</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20outcomes" title=" student outcomes"> student outcomes</a>, <a href="https://publications.waset.org/abstracts/search?q=course%20learning%20outcomes" title=" course learning outcomes"> course learning outcomes</a>, <a href="https://publications.waset.org/abstracts/search?q=question%20attributes" title=" question attributes"> question attributes</a> </p> <a href="https://publications.waset.org/abstracts/42958/an-expert-system-for-assessment-of-learning-outcomes-for-abet-accreditation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42958.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">251</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">5296</span> Effect of Lemongrass Oil Containing Polycaprolactone Nanofibers on Biofilm Formation of Proteus mirabilis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gulcan%20Sahal">Gulcan Sahal</a>, <a href="https://publications.waset.org/abstracts/search?q=Behzad%20Nasseri"> Behzad Nasseri</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Akbar%20Ebrahimi"> Ali Akbar Ebrahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Isil%20Seyis%20Bilkay"> Isil Seyis Bilkay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Proteus mirabilis strains which are natural colonizers of healthy individuals’ gastrointestinal tract are also known as common causes of catheter-associated urinary tract infections. Nowadays, as a result of an increased resistance to various antimicrobial drugs, there has been a growing interest in natural products. Therefore, the aim of this study is to investigate biofilm formation of P. mirabilis strains on lemongrass oil containing polycaprolactone nanofibers. Polycaprolactone nanofibers with different lemongrass oil concentrations were successfully prepared by electrospinning and biofilm formation of P. mirabilis on these nanofibers were determined by ‘Crystal Violet Staining Assay’. According to our results, polycaprolactone nanofibers with some lemongrass oil concentrations, decreased biofilm formation of P. mirabilis and this effect increased in parallel with the increase in lemongrass oil concentration. Our results indicate that, polycaprolactone nanofibers with some concentrations of lemongrass oil may provide a treatment against catheter-associated urinary tract infections by means of causing an inhibition on biofilm formation of P. mirabilis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-biofilm" title="anti-biofilm">anti-biofilm</a>, <a href="https://publications.waset.org/abstracts/search?q=biofilm%20formation" title=" biofilm formation"> biofilm formation</a>, <a href="https://publications.waset.org/abstracts/search?q=essential%20oils" title=" essential oils"> essential oils</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofibers" title=" nanofibers"> nanofibers</a>, <a href="https://publications.waset.org/abstracts/search?q=proteus%20mirabilis" title=" proteus mirabilis"> proteus mirabilis</a> </p> <a href="https://publications.waset.org/abstracts/55250/effect-of-lemongrass-oil-containing-polycaprolactone-nanofibers-on-biofilm-formation-of-proteus-mirabilis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55250.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">412</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">5295</span> A Mathematical Analysis of a Model in Capillary Formation: The Roles of Endothelial, Pericyte and Macrophages in the Initiation of Angiogenesis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Serdal%20Pamuk">Serdal Pamuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Irem%20Cay"> Irem Cay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Our model is based on the theory of reinforced random walks coupled with Michealis-Menten mechanisms which view endothelial cell receptors as the catalysts for transforming both tumor and macrophage derived tumor angiogenesis factor (TAF) into proteolytic enzyme which in turn degrade the basal lamina. The model consists of two main parts. First part has seven differential equations (DE’s) in one space dimension over the capillary, whereas the second part has the same number of DE’s in two space dimensions in the extra cellular matrix (ECM). We connect these two parts via some boundary conditions to move the cells into the ECM in order to initiate capillary formation. But, when does this movement begin? To address this question we estimate the thresholds that activate the transport equations in the capillary. We do this by using steady-state analysis of TAF equation under some assumptions. Once these equations are activated endothelial, pericyte and macrophage cells begin to move into the ECM for the initiation of angiogenesis. We do believe that our results play an important role for the mechanisms of cell migration which are crucial for tumor angiogenesis. Furthermore, we estimate the long time tendency of these three cells, and find that they tend to the transition probability functions as time evolves. We provide our numerical solutions which are in good agreement with our theoretical results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=angiogenesis" title="angiogenesis">angiogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=capillary%20formation" title=" capillary formation"> capillary formation</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20analysis" title=" mathematical analysis"> mathematical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=steady-state" title=" steady-state"> steady-state</a>, <a href="https://publications.waset.org/abstracts/search?q=transition%20probability%20function" title=" transition probability function"> transition probability function</a> </p> <a href="https://publications.waset.org/abstracts/74388/a-mathematical-analysis-of-a-model-in-capillary-formation-the-roles-of-endothelial-pericyte-and-macrophages-in-the-initiation-of-angiogenesis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74388.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">156</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">5294</span> Application of Argumentation for Improving the Classification Accuracy in Inductive Concept Formation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vadim%20Vagin">Vadim Vagin</a>, <a href="https://publications.waset.org/abstracts/search?q=Marina%20Fomina"> Marina Fomina</a>, <a href="https://publications.waset.org/abstracts/search?q=Oleg%20Morosin"> Oleg Morosin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper contains the description of argumentation approach for the problem of inductive concept formation.

The present work aims to model the relative motion dynamics in terms of change in classical orbital parameters between the two satellites-chief and deputy- under Earth’s oblateness effect. The required impulsive thrust control is calculated to minimize these orbital parameter changes. The formation configuration is initialized by selecting a set of orbital parameters for the chief and deputy satellites such that bounded motion is maintained for a long time in a J_2-invariant relative non-circular orbit between the satellites. The solution of J_2-modified Hill’s equations is also derived in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=satellite" title="satellite">satellite</a>, <a href="https://publications.waset.org/abstracts/search?q=formation%20flight" title=" formation flight"> formation flight</a>, <a href="https://publications.waset.org/abstracts/search?q=j2%20effect" title=" j2 effect"> j2 effect</a>, <a href="https://publications.waset.org/abstracts/search?q=control" title=" control"> control</a> </p> <a href="https://publications.waset.org/abstracts/78015/some-aspects-on-formation-initialization-and-its-maintenance-of-leo-satellites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78015.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">275</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">5292</span> The Consequences of Regime Change in Iraq; Formation and Continuation of Geopolitical Crises</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Asghar%20Sotoudeh">Ali Asghar Sotoudeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since the US invasion of Iraq in 2003 and the subsequent regime change, internal conflicts between political and ethnic-religious groups have become a hallmark of Iraqi political dynamism. The most important manifestations of these conflicts are the Kurdish-central government conflicts, as well as fundamentalism since 2003. As a result, it seems not only US presence in Iraq under the pretext of fighting terrorism and expanding democracy has not had a positive effect on controlling fundamentalism and political stability in Iraq, but it has paved the way for the formation and continuation of geopolitical crises in the form of disputes over territory and sources of power. In this regard, given the importance of the study, the main purpose of this study is to examine the process of the impact of US regime-change policy on the formation and continuation of geopolitical crises in Iraq. The central question of this study is, what effect has the US regime change policy had on Iraq's domestic political processes? Findings show that regime change and subsequent imposed federalism have widened the gaps in Iraq's sectarian-ethnic system. As a result, the geopolitical crisis in the context of the dispute over geographical territory and sources of power between ethnic-religious groups has become the most important political dynamic in Iraq since the occupation.

To this end, several heuristics to extract such partial dependencies are formulated, followed by the hereby proposed evaluation methods denoted as Proportional Graph Matcher (PGM) and Conversion to Normal String Representation (Nor-Str), designed to better capture the accuracy level of QDMR predictions. Experiments are conducted to demonstrate the efficacy of the proposed evaluation methods and show the added value suggested by one of them- the Nor-Str, for better distinguishing between high and low-quality QDMR when predicted by models such as COPYNET. This work represents an important step forward in the development of better evaluation methods for QDMR predictions, which will be critical for improving the accuracy and reliability of natural language question-answering systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NLP" title="NLP">NLP</a>, <a href="https://publications.waset.org/abstracts/search?q=question%20answering" title=" question answering"> question answering</a>, <a href="https://publications.waset.org/abstracts/search?q=question%20decomposition%20meaning%20representation" title=" question decomposition meaning representation"> question decomposition meaning representation</a>, <a href="https://publications.waset.org/abstracts/search?q=QDMR%20evaluation%20metrics" title=" QDMR evaluation metrics"> QDMR evaluation metrics</a> </p> <a href="https://publications.waset.org/abstracts/173593/evaluation-methods-for-question-decomposition-formalism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173593.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">78</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">5289</span> The Maximum Throughput Analysis of UAV Datalink 802.11b Protocol</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Inkyu%20Kim">Inkyu Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=SangMan%20Moon"> SangMan Moon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This IEEE 802.11b protocol provides up to 11Mbps data rate, whereas aerospace industry wants to seek higher data rate COTS data link system in the UAV.

Responding to close-ended questions assertively improve content quality in the AnswerXchange in 90% of cases. Answering knowledge questions with web links increases the likelihood of receiving a negative vote from 60% of the askers. Our findings provide a rationale for employing the uplift modeling approach for AnswerXchange operations. <p class="card-text"><strong>Keywords:</strong> <a
