microbiome, or the population of bacteria and other microorganisms living in the human body, has been linked with human health. Various research has examined the connection with both illness status and the composition of the human microbiome, even though current studies indicate that the gut microbiome influences the mucosa and immune system. A significant amount of effort is being put into understanding the human microbiome's natural history in terms of health outcomes while also expanding our comprehension of the molecular connections between the microbiome and the host. To maintain health and avoid disease, these efforts ultimately seek to find efficient methods for recovering human microbial communities. This review article describes how the human microbiome leads to chronic diseases and discusses evidence for an important significant disorder that is related to the microbiome and linked to prostate cancer: chronic prostatitis (CP). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urobiome" title="urobiome">urobiome</a>, <a href="https://publications.waset.org/abstracts/search?q=chronic%20prostatitis" title=" chronic prostatitis"> chronic prostatitis</a>, <a href="https://publications.waset.org/abstracts/search?q=metagenomic" title=" metagenomic"> metagenomic</a>, <a href="https://publications.waset.org/abstracts/search?q=urinary%20microbiome" title=" urinary microbiome"> urinary microbiome</a> </p> <a href="https://publications.waset.org/abstracts/159463/metagenomics-urinary-microbiome-and-chronic-prostatitis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159463.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">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> Human Microbiome Hidden Association with Chronic and Autoimmune Diseases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elmira%20Davasaz%20Tabrizi">Elmira Davasaz Tabrizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mu%CC%88s%CC%A7teba%20Sevil"> Müşteba Sevil</a>, <a href="https://publications.waset.org/abstracts/search?q=Ercan%20Arican"> Ercan Arican</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent decades, there has been a sharp increase in the prevalence of several unrelated chronic diseases. The use of long-term antibiotics for chronic illnesses is increasing. The antibiotic resistance occurrence and its relationship with host microbiomes are still unclear. Properties of the identifying antibodies have been the focus of chronic disease research, such as prostatitis or autoimmune. The immune system is made up of a complicated but well-organized network of cell types that constantly monitor and maintain their surroundings. The regulated homeostatic interaction between immune system cells and their surrounding environment shapes the microbial flora. Researchers believe that the disappearance of special bacterial species from our ancestral microbiota might have altered the body flora that can cause a rise in disease during the human life span. This unpleasant pattern demonstrates the importance of focusing on discovering and revealing the root causes behind the disappearance or alteration of our microbiota. In this review, we gathered the results of some studies that reveal changes in the diversity and quantity of microorganisms that may affect chronic and autoimmune diseases. Additionally, a Ph.D. thesis that is still in process as Metagenomic studies in chronic prostatitis samples is mentioned. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metagenomic" title="metagenomic">metagenomic</a>, <a href="https://publications.waset.org/abstracts/search?q=autoimmune" title=" autoimmune"> autoimmune</a>, <a href="https://publications.waset.org/abstracts/search?q=prostatitis" title=" prostatitis"> prostatitis</a>, <a href="https://publications.waset.org/abstracts/search?q=microbiome" title=" microbiome"> microbiome</a> </p> <a href="https://publications.waset.org/abstracts/159476/human-microbiome-hidden-association-with-chronic-and-autoimmune-diseases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159476.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">96</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">38</span> Fast Terminal Sliding Mode Controller For Quadrotor UAV</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Tabrizi">Vahid Tabrizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20GHasemi">Reza GHasemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmadreza%20Vali">Ahmadreza Vali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents robust nonlinear control law for a quadrotor UAV using fast terminal sliding mode control.

In this context, a lot of national and international studies have been done from different aspects. But in the meantime, and in connection with women issues, researchers in Communication Science and Sociology are interested in two topics “use of pornographic images of women” and “repeated representations of women in traditional roles and gender stereotypes by emphasizing the differences between men and women”, more than any other topics. Considering a number of changes that have occurred in social institutions and at different levels, the main research question currently are, what is the role of women in our TV ads and how are they represented in them? Do the local television ads represent women in the same issues as the researchers on this topic has proposed or new changes have occurred? Many scholars and thinkers in the field of media outlet that, today, media not just focus on women as gender issues or sex objects, but also seeks to strengthen the gender division of labor in the family and emphasize on the traditional muliebrity and masculinity stereotype. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=women" title="women">women</a>, <a href="https://publications.waset.org/abstracts/search?q=representation" title=" representation"> representation</a>, <a href="https://publications.waset.org/abstracts/search?q=tv%20commercials" title=" tv commercials"> tv commercials</a>, <a href="https://publications.waset.org/abstracts/search?q=advertising%20sociology" title=" advertising sociology"> advertising sociology</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20stereotypes" title=" gender stereotypes"> gender stereotypes</a> </p> <a href="https://publications.waset.org/abstracts/24794/representation-of-women-in-tv-commercials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24794.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">521</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">31</span> The Economic Valuation of Public Support Ecosystem: A Contingent Valuation Study in Setiu Wetland, Terengganu Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elmira%20Shamshity">Elmira Shamshity</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to explore the economic approach for the Setiu wetland evaluation as a future protection strategy. A questionnaire survey was used based on the single-bounded dichotomous choice, contingent valuation method to differentiate individuals’ Willingness to Pay (WTP) for the conservation of the Setiu wetland. The location of study was Terengganu province in Malaysia. The results of the random questionnaire survey showed that protection of Setiu ecosystem is important to the indigenous community. The mean WTP for protection of ecosystem Setiu wetland was 12.985 Ringgit per month per household for 10 years. There was significant variation in the stated amounts of WTP based on the respondents’ knowledge, household income, educational level, and the bid amounts. The findings of this study may help improving understanding the WTP of indigenous people for the protection of wetland, and providing useful information for policy makers to design an effective program of ecosystem protection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=willingness%20to%20pay" title="willingness to pay">willingness to pay</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystem" title=" ecosystem"> ecosystem</a>, <a href="https://publications.waset.org/abstracts/search?q=setiu%20wetland" title=" setiu wetland"> setiu wetland</a>, <a href="https://publications.waset.org/abstracts/search?q=Terengganu%20Malaysia" title=" Terengganu Malaysia"> Terengganu Malaysia</a> </p> <a href="https://publications.waset.org/abstracts/32201/the-economic-valuation-of-public-support-ecosystem-a-contingent-valuation-study-in-setiu-wetland-terengganu-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32201.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">605</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">30</span> Stability of Ochratoxin a During Bread Making Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Heidari">Sara Heidari</a>, <a href="https://publications.waset.org/abstracts/search?q=Jafar%20Mohammadzadeh%20Milani"> Jafar Mohammadzadeh Milani</a>, <a href="https://publications.waset.org/abstracts/search?q=Elmira%20Pouladi%20Borj"> Elmira Pouladi Borj</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research, stability of Ochratoxin A (OTA) during bread making process including fermentation with yeasts (Saccharomyces cerevisiae) and Sourdough (Lactobacillus casei, Lactobacillus rhamnosus, Lactobacillus acidophilus and Lactobacillus fermentum) and baking at 200°C were examined. Bread was prepared on a pilot-plant scale by using wheat flour spiked with standard solution of OTA. During this process, mycotoxin levels were determined after fermentation of the dough with sourdough and three types of yeast including active dry yeast, instant dry yeast and compressed yeast after further baking 200°C by high performance liquid chromatography (HPLC) with ﬂuorescence detector after extraction and clean-up on an immunoafﬁnity column. According to the results, the highest stability of was observed in the first fermentation (first proof), while the lowest stability was observed in the baking stage in comparison to contaminated flour. In addition, compressed yeast showed the maximum impact on stability of OTA during bread making process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ochratoxin%20A" title="Ochratoxin A">Ochratoxin A</a>, <a href="https://publications.waset.org/abstracts/search?q=bread" title=" bread"> bread</a>, <a href="https://publications.waset.org/abstracts/search?q=dough" title=" dough"> dough</a>, <a href="https://publications.waset.org/abstracts/search?q=yeast" title=" yeast"> yeast</a>, <a href="https://publications.waset.org/abstracts/search?q=sourdough" title=" sourdough"> sourdough</a> </p> <a href="https://publications.waset.org/abstracts/25928/stability-of-ochratoxin-a-during-bread-making-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25928.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">576</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> The Investigation of Relationship between Accounting Information and the Value of Companies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Golamhassan%20Ghahramani%20Aghdam">Golamhassan Ghahramani Aghdam</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedram%20Bavili%20Tabrizi"> Pedram Bavili Tabrizi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this research is to investigate the relationship between accounting information and the value of the companies accepted in Tehran Exchange Market.

The derivation comprises determining equations of the motion of the quadrotor in three dimensions and approximating the actuation forces through the modeling of aerodynamic coefficients and electric motor dynamics. The robust nonlinear control strategy includes a smooth second order non-singular terminal sliding mode control which is applied to stabilizing this model. The control method is on the basis of super twisting algorithm for removing the chattering and producing smooth control signal. Also, nonsingular terminal sliding mode idea is used for introducing a nonlinear sliding variable that guarantees the finite time convergence in sliding phase. Simulation results show that the proposed algorithm is robust against uncertainty or disturbance and guarantees a fast and precise control signal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quadrotor%20UAV" title="quadrotor UAV">quadrotor UAV</a>, <a href="https://publications.waset.org/abstracts/search?q=nonsingular%20terminal%20sliding%20mode" title=" nonsingular terminal sliding mode"> nonsingular terminal sliding mode</a>, <a href="https://publications.waset.org/abstracts/search?q=second%20order%20sliding%20mode%20t" title=" second order sliding mode t"> second order sliding mode t</a>, <a href="https://publications.waset.org/abstracts/search?q=electronics" title=" electronics"> electronics</a>, <a href="https://publications.waset.org/abstracts/search?q=control" title=" control"> control</a>, <a href="https://publications.waset.org/abstracts/search?q=signal%20processing" title=" signal processing"> signal processing</a> </p> <a href="https://publications.waset.org/abstracts/13906/smooth-second-order-nonsingular-terminal-sliding-mode-control-for-a-6-dof-quadrotor-uav" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13906.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">441</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> Examines the Proportionality between the Needs of Industry and Technical and Vocational Training of Male and Female Vocational Schools</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalil%20Aryanfar">Khalil Aryanfar</a>, <a href="https://publications.waset.org/abstracts/search?q=Pariya%20Gholipor"> Pariya Gholipor</a>, <a href="https://publications.waset.org/abstracts/search?q=Elmira%20Hafez"> Elmira Hafez </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examines the proportionality between the needs of industry and technical and vocational training of male and female vocational schools.

The assembly of these molecules into crystalline fibrous structures occurs as a result of reversible interactions such as π-stacking, hydrogen-bonding, and van der Waals interactions. Bisamide organogelators with two amide groups have been used as one of LMWGs which show efficient assembly behavior via hydrogen bonding for network formation, the formation of a crystalline network for solvent entrapment. In this study, different bisamide gelators with different lengths of alkyl chains have been added to the bisamide parent gels. The effect of the addition of bisamide additives on the gelation of bisamide gels is described. Investigation of the thermal properties of the gels by differential scanning calorimetry and dropping ball techniques indicated that the bisamide gels can be formed by the addition of a high concentration of the second bisamide components. The microstructure of the gels with different gelator components has been visualized with scanning electron microscopy (SEM) which has shown systematic woven, platelet-like, and a combination of those morphologies for different gels. Examining the addition of a range of bisamide additives with different structural characteristics than the parent bisamide gels has confirmed the effect of the molecular structure on the morphology of the bisamide gels and their final properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bisamide%20organogelator%20additives" title="bisamide organogelator additives">bisamide organogelator additives</a>, <a href="https://publications.waset.org/abstracts/search?q=gel%20morphology" title=" gel morphology"> gel morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=gel%20properties" title=" gel properties"> gel properties</a>, <a href="https://publications.waset.org/abstracts/search?q=self-assembly" title=" self-assembly"> self-assembly</a> </p> <a href="https://publications.waset.org/abstracts/138626/the-effect-of-the-addition-of-additives-on-the-properties-of-bisamide-organogels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138626.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">203</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> The Effect of Aerobic Training Program on Some Pro-Inflammatory Cytokine in Smokers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laleh%20Behboudi%20Tabrizi">Laleh Behboudi Tabrizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Melika%20Naserzare"> Melika Naserzare</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Accumulating experimental and epidemiologic data smoker individuals are more prone to systemic inflammation than non-smokers. In this study we aimed to determine serum TNF-α and C-reactive protein (CRP) as pro-inflammatory cytokines in response to 3 months aerobic training in smoker men. A total 30 middle-aged healthy smokers selected for participate in this study and were divided into either control or exercise groups. The subjects in exercise group were completed a 3 months aerobic training program for 3 sessions per week at 60 – 80 % of maximal heart rate. Those in control group did nit participated in exercise training. Pre and post-training of CRP and TNF-α were measured in two groups. Student’s t-tests for paired samples were performed to determine whether there were signigcant within-group changes in the outcomes. P value of <0.05 was accepted as significant. No significant differences were found in anthropometrical and biochemical markers between two groups at baseline. Aerobic training program resulted in a significant decrease in anthropometrical markers and serum TNF-α but not in serum CRP in exercise group. All variables remained without changes in control groups. Based on these finding, it is concluded that aerobic training can be improve inflammatory cytokine with emphasis on TNF-α in smokers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cigarette" title="cigarette">cigarette</a>, <a href="https://publications.waset.org/abstracts/search?q=cytokine" title=" cytokine"> cytokine</a>, <a href="https://publications.waset.org/abstracts/search?q=chronic%20training" title=" chronic training"> chronic training</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammation" title=" inflammation"> inflammation</a> </p> <a href="https://publications.waset.org/abstracts/38136/the-effect-of-aerobic-training-program-on-some-pro-inflammatory-cytokine-in-smokers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38136.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">313</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Comparison between Effects of Free Curcumin and Curcumin Loaded NIPAAm-MAA Nanoparticles on Telomerase and Pinx1 Gene Expression in Lung Cancer Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20Pilehvar-Soltanahmadi">Y.

In this article, we compared the effects of pure curcumin and curcumin-loaded NIPAAm-MAA nanoparticles on telomerase and PinX1 gene expression in a lung cancer cell line. A tetrazolium-based assay was used for determination of cytotoxic effects of curcumin on the Calu-6 lung cancer cell line and telomerase and pinX1 gene expression was measured with real-time PCR. MTT assay showed that Curcumin-loaded NIPAAm-MAA inhibited the growth of the Calu-6 lung cancer cell line in a time and dose-dependent manner. Our q-PCR results showed that the expression of telomerase gene was effectively reduced as the concentration of curcumin-loaded NIPAAm-MAA increased while expression of the PinX1 gene became elevated. The results showed that curcumin loaded NIPAAm-MAA exerted cytotoxic effects on the Calu-6 cell line through down-regulation of telomerase and stimulation of pinX1 gene expression. NIPPAm-MAA could be the good carrier for such kinds of hydrophobic agent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=curcumin" title="curcumin">curcumin</a>, <a href="https://publications.waset.org/abstracts/search?q=NIPAAm-MAA" title=" NIPAAm-MAA"> NIPAAm-MAA</a>, <a href="https://publications.waset.org/abstracts/search?q=PinX1" title=" PinX1"> PinX1</a>, <a href="https://publications.waset.org/abstracts/search?q=telomerase" title=" telomerase"> telomerase</a>, <a href="https://publications.waset.org/abstracts/search?q=lung%20cancer%20cells" title=" lung cancer cells"> lung cancer cells</a> </p> <a href="https://publications.waset.org/abstracts/37740/comparison-between-effects-of-free-curcumin-and-curcumin-loaded-nipaam-maa-nanoparticles-on-telomerase-and-pinx1-gene-expression-in-lung-cancer-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37740.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">301</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> Study of the Chronic Effects of CRACK on Some Biochemical Parameters Including Triglycerides, Cholesterol, HDL, LDL, VLDL, Amylase, Lipase, Albumin, Protein in Rat</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Jafarzadeh">Alireza Jafarzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahram%20Amu-Oqhli%20Tabrizi"> Bahram Amu-Oqhli Tabrizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadi%20Khayat%20Nouri"> Hadi Khayat Nouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Arash%20Khaki"> Arash Khaki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> 30 head of adult Vistar rats were chosen to evaluate the chronic narcotic effects of crack on some biochemical parameters.

More precisely, this study aims at classifying the different types of expansion used in subtitles as well as investigating the appropriateness or inappropriateness of the application of each type. To achieve this end, three English movies; namely, The Net (1995), Contact (1997) and Mission Impossible 2 (2000), available with Persian subtitles, were selected for the study. To collect the data, the above mentioned movies were watched and those parts of the Persian subtitles in which expansion had been used were identified and extracted along with their English dialogs. Then, the extracted Persian subtitles were classified based on the reason that led to expansion in each case. Next, the appropriateness or inappropriateness of using expansion in the extracted Persian subtitles was descriptively investigated. Finally, an equivalent not containing any expansion was proposed for those cases in which the meaning could be fully transferred without this strategy. The findings of the study indicated that the reasons range from explicitation (explicitation of visual, co-textual and contextual information), mistranslation and paraphrasing to the preferences of subtitlers. Furthermore, it was found that the employment of expansion strategy was inappropriate in all cases except for those caused by explicitation of contextual information since correct and shorter equivalents which were equally capable of conveying the intended meaning could be posited for the original dialogs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=audiovisual%20translation" title="audiovisual translation">audiovisual translation</a>, <a href="https://publications.waset.org/abstracts/search?q=English%20crime%20movies" title=" English crime movies"> English crime movies</a>, <a href="https://publications.waset.org/abstracts/search?q=expansion%20strategies" title=" expansion strategies"> expansion strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=Persian%20subtitles" title=" Persian subtitles"> Persian subtitles</a> </p> <a href="https://publications.waset.org/abstracts/34785/a-study-on-explicitation-strategies-employed-in-persian-subtitling-of-english-crime-movies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34785.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">468</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Comprehensive Review of Adversarial Machine Learning in PDF Malware</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Preston%20Nabors">Preston Nabors</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasseh%20Tabrizi"> Nasseh Tabrizi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Portable Document Format (PDF) files have gained significant popularity for sharing and distributing documents due to their universal compatibility. However, the widespread use of PDF files has made them attractive targets for cybercriminals, who exploit vulnerabilities to deliver malware and compromise the security of end-user systems. This paper reviews notable contributions in PDF malware detection, including static, dynamic, signature-based, and hybrid analysis. It presents a comprehensive examination of PDF malware detection techniques, focusing on the emerging threat of adversarial sampling and the need for robust defense mechanisms. The paper highlights the vulnerability of machine learning classifiers to evasion attacks. It explores adversarial sampling techniques in PDF malware detection to produce mimicry and reverse mimicry evasion attacks, which aim to bypass detection systems. Improvements for future research are identified, including accessible methods, applying adversarial sampling techniques to malicious payloads, evaluating other models, evaluating the importance of features to malware, implementing adversarial defense techniques, and conducting comprehensive examination across various scenarios. By addressing these opportunities, researchers can enhance PDF malware detection and develop more resilient defense mechanisms against adversarial attacks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adversarial%20attacks" title="adversarial attacks">adversarial attacks</a>, <a href="https://publications.waset.org/abstracts/search?q=adversarial%20defense" title=" adversarial defense"> adversarial defense</a>, <a href="https://publications.waset.org/abstracts/search?q=adversarial%20machine%20learning" title=" adversarial machine learning"> adversarial machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=intrusion%20detection" title=" intrusion detection"> intrusion detection</a>, <a href="https://publications.waset.org/abstracts/search?q=PDF%20malware" title=" PDF malware"> PDF malware</a>, <a href="https://publications.waset.org/abstracts/search?q=malware%20detection" title=" malware detection"> malware detection</a>, <a href="https://publications.waset.org/abstracts/search?q=malware%20detection%20evasion" title=" malware detection evasion"> malware detection evasion</a> </p> <a href="https://publications.waset.org/abstracts/184556/comprehensive-review-of-adversarial-machine-learning-in-pdf-malware" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184556.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">39</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> Investigate and Compare the Characteristics of Entrepreneurship among Students in Senior Secondary Schools in the Academic </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalil%20Aryanfar">Khalil Aryanfar</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahrzad%20Sanjari">Shahrzad Sanjari</a>, <a href="https://publications.waset.org/abstracts/search?q=Pariya%20Gholipor"> Pariya Gholipor</a>, <a href="https://publications.waset.org/abstracts/search?q=Elmira%20Hafez"> Elmira Hafez </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study aimed to investigate and compare the characteristics of entrepreneurship among students in senior secondary schools in the academic year 2008-2009 in Tabriz city.

To achieve this goal, thirty experienced male and female translation teachers from the four types of the universities offering the program were invited to an in-depth 30-minute one-session semi-structured interview. The responses provided showed how much discrepancy exists among the Iranian translation teachers (as developers of final translation tests), who are least informed with the current translation evaluation methods. It was also revealed that the criteria they use for developing such tests and scoring student translations are not theory-driven but are highly subjective, mainly based on their personal experience and intuition. Hence, the quality and accountability of such tests are under serious question. The results also confirmed that the dominant method commonly and currently practiced is the purely essay-type format. To remedy the situation, some suggestions are in order. As part of the solution, to improve the reliability and validity of such tests, the present summative, product-oriented evaluation should be accompanied with some formative, process-oriented methods of evaluation. Training the teachers and helping them get acquainted with modern principles of translation evaluation as well as the existing models, and rating scales does improve the quality of academic translation evaluation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iranian%20universities" title="Iranian universities">Iranian universities</a>, <a href="https://publications.waset.org/abstracts/search?q=students%E2%80%99%20academic%20translations" title=" students’ academic translations"> students’ academic translations</a>, <a href="https://publications.waset.org/abstracts/search?q=translation%20final%20tests" title=" translation final tests"> translation final tests</a>, <a href="https://publications.waset.org/abstracts/search?q=undergraduate%20translation%20programs" title=" undergraduate translation programs"> undergraduate translation programs</a> </p> <a href="https://publications.waset.org/abstracts/34678/an-investigation-of-final-tests-of-translation-as-practiced-in-iranian-undergraduate-english-translation-program-the-instructors-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34678.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">549</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> Zakariya Multaniand and his Role in the Spread of Islam and Suhrawardiyya in the Subcontinent</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Momeni">Mahdi Momeni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The arrival of Mysticism to the subcontinent can be generally divided into two periods. The first period, was the Sporadic arrival of Sufis whom were traveling to the subcontinent according to the tradition of disquisition and the second period was; when the Sufi dynasties were sending missionaries and caliphs to guide and promote people from different direction to that land. Among the Sufi dynasty that entered to India in the thirteenth century, two dynasties of Chishti and Suhrawardîya were more successful than other Sufi dynasties. And thus they are very important in the spread of Islam and Mysticism to the subcontinent. Suhrawardiyya dynasty was founded by Sheikh Ziauddin Abu Najib Suhrawardi and was developed and spread by his nephew Sheikh Shahabuddin Suhrawardi Abo hafs Omar. Sheikh Shahabuddin sent many Caliphs and missionaries to India. Among these missionaries were People like Sultan Sakhi Sarwar, Seyyed Noureddin Mobarak Ghaznavi, Sheikh Jalal al-din Tabrizi and Sheikh Zakariya Multani. Since Suhrawardiyya doctrine relies on Asceticism and Sharia, so one of the important elements among Suhrawardiyya missionaries was inviting people to Islam. Accordingly Sheikh Shahab Caliphs had a great role in the spread of Islam and Mysticism in different territories, especially India. Such that it can be pointed out is the the role of Sheikh Baha-ud-din Zakariya Multani, the founder of Suhrawardiyya Dynasty in India. Sheikh Zakaria Multani after working in three areas, establishing monasteries, training managers, having numerous trips to different places, participating to social affairs provided the spread of Islam and Mysticism in subcontinent. This paper studies his role and actions in the subcontinent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=islam" title="islam">islam</a>, <a href="https://publications.waset.org/abstracts/search?q=sufism" title=" sufism"> sufism</a>, <a href="https://publications.waset.org/abstracts/search?q=Suhrawardiyya" title=" Suhrawardiyya"> Suhrawardiyya</a>, <a href="https://publications.waset.org/abstracts/search?q=subcontinent" title=" subcontinent"> subcontinent</a>, <a href="https://publications.waset.org/abstracts/search?q=Multan" title=" Multan"> Multan</a> </p> <a href="https://publications.waset.org/abstracts/26260/zakariya-multaniand-and-his-role-in-the-spread-of-islam-and-suhrawardiyya-in-the-subcontinent" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26260.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">506</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> Evaluation and Comparison of Male and Female Students’ Life Skills of Theoretical, Technical-Vocational and Job and Knowledge Branches of Secondary High School Period</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalil%20Aryanfar">Khalil Aryanfar</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahrzad%20Sanjari"> Shahrzad Sanjari</a>, <a href="https://publications.waset.org/abstracts/search?q=Elmira%20Hafez"> Elmira Hafez</a>, <a href="https://publications.waset.org/abstracts/search?q=Pariya%20Gholipor"> Pariya Gholipor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to Evaluate and compare the male and female students’ life skills of theoretical, technical-vocational and Job and Knowledge branches of secondary high school period.

Cloud computing is useful to overcome a number of problems in various Information Technology (IT) domains such as Geographical Information Systems (GIS), Scientific Research, e-Governance Systems, Decision Support Systems, ERP, Web Application Development, Mobile Technology, etc. Companies can use Cloud Computing services to store large amounts of data that can be accessed from anywhere on Earth and also at any time. Such services are rented by the client companies where the actual rent depends upon the amount of data stored on the cloud and also the amount of processing power used in a given time period. The resources offered by the cloud service companies are flexible in the sense that the user companies can increase or decrease their storage requirements or the processing power requirements at any time, thus minimizing the overall rental cost of the service they receive. In addition, the Cloud Computing service providers offer fast processors and applications software that can be shared by their clients. This is especially important for small companies with limited budgets which cannot afford to purchase their own expensive hardware and software. This paper is an overview of the Cloud Computing, giving its types, principles, advantages, and disadvantages. In addition, the paper gives some example engineering applications of Cloud Computing and makes suggestions for possible future applications in the field of engineering. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing" title="cloud computing">cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20systems" title=" cloud systems"> cloud systems</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20services" title=" cloud services"> cloud services</a>, <a href="https://publications.waset.org/abstracts/search?q=IaaS" title=" IaaS"> IaaS</a>, <a href="https://publications.waset.org/abstracts/search?q=PaaS" title=" PaaS"> PaaS</a>, <a href="https://publications.waset.org/abstracts/search?q=SaaS" title=" SaaS"> SaaS</a> </p> <a href="https://publications.waset.org/abstracts/71816/a-review-on-cloud-computing-and-internet-of-things" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71816.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">233</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> Chrysin-Loaded PLGA-PEG Nanoparticles Designed for Enhanced Inhibitory Effect on the Breast Cancer Cell Line</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faraz%20Zarghami">Faraz Zarghami</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Anari"> Elham Anari</a>, <a href="https://publications.waset.org/abstracts/search?q=Nosratollah%20Zarghami"> Nosratollah Zarghami</a>, <a href="https://publications.waset.org/abstracts/search?q=Yones%20Pilehvar-Soltanahmadi"> Yones Pilehvar-Soltanahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abolfazl%20Akbarzadeh"> Abolfazl Akbarzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sepideh%20Jalilzadeh-Tabrizi"> Sepideh Jalilzadeh-Tabrizi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of nanotherapy has presented a new method of drug delivery targeted directly to the neoplasmic tissues, to maximize the action with fewer dose requirements. In the past two decades, poly(lactic-co-glycolic acid) (PLGA) has frequently been investigated by many researchers and is a popular polymeric candidate, due to its biocompatibility and biodegradability, exhibition of a wide range of erosion times, tunable mechanical properties, and most notably, because it is a FDA-approved polymer. Chrysin is a natural flavonoid which has been reported to have some significant biological effects on the processes of chemical defense, nitrogen fixation, inflammation, and oxidation. However, the low solubility in water decreases its bioavailability and consequently disrupts the biomedical benefits. Being loaded with PLGA-PEG increases chrysin solubility and drug tolerance, and decreases the discordant effects of the drug. The well-structured chrysin efficiently accumulates in the breast cancer cell line (T47D). In the present study, the structure and chrysin loading were delineated using proton nuclear magnetic resonance (HNMR), Fourier-transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM), and the in vitro cytotoxicity of pure and nanochrysin was studied by the MTT assay. Next, the RNA was exploited and the cytotoxic effects of chrysin were studied by real-time PCR. In conclusion, the nanochrysin therapy developed is a novel method that could increase cytotoxicity to cancer cells without damaging the normal cells, and would be promising in breast cancer therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MTT%20assay" title="MTT assay">MTT assay</a>, <a href="https://publications.waset.org/abstracts/search?q=chrysin" title=" chrysin"> chrysin</a>, <a href="https://publications.waset.org/abstracts/search?q=flavonoids" title=" flavonoids"> flavonoids</a>, <a href="https://publications.waset.org/abstracts/search?q=nanotherapy" title=" nanotherapy"> nanotherapy</a> </p> <a href="https://publications.waset.org/abstracts/37725/chrysin-loaded-plga-peg-nanoparticles-designed-for-enhanced-inhibitory-effect-on-the-breast-cancer-cell-line" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37725.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">14</span> Synthesis and Characterization of Silver/Graphene Oxide Co-Decorated TiO2 Nanotubular Arrays for Biomedical Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Rafieerad">Alireza Rafieerad</a>, <a href="https://publications.waset.org/abstracts/search?q=Bushroa%20Abd%20Razak"> Bushroa Abd Razak</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahman%20Nasiri%20Tabrizi"> Bahman Nasiri Tabrizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamunarani%20Vadivelu"> Jamunarani Vadivelu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, reports on the fabrication of nanotubular arrays have generated considerable scientific interest, owing to the broad range of applications of the oxide nanotubes in solar cells, orthopedic and dental implants, photocatalytic devices as well as lithium-ion batteries. A more attractive approach for the fabrication of oxide nanotubes with controllable morphology is the electrochemical anodization of substrate in a fluoride-containing electrolyte. Consequently, titanium dioxide nanotubes (TiO2 NTs) have been highly considered as an applicable material particularly in the district of artificial implants. In addition, regarding long-term efficacy and reasons of failing and infection after surgery of currently used dental implants required to enhance the cytocompatibility properties of Ti-based bone-like tissue. As well, graphene oxide (GO) with relevant biocompatibility features in tissue sites, osseointegration and drug delivery functionalization was fully understood. Besides, the boasting antibacterial ability of silver (Ag) remarkably provided for implantable devices without infection symptoms. Here, surface modification of Ti–6Al–7Nb implants (Ti67IMP) by the development of Ag/GO co-decorated TiO2 NTs was examined. Initially, the anodic TiO2 nanotubes obtained at a constant potential of 60 V were annealed at 600 degree centigrade for 2 h to improve the adhesion of the coating. Afterward, the Ag/GO co-decorated TiO2 NTs were developed by spin coating on Ti67IM. The microstructural features, phase composition and wettability behavior of the nanostructured coating were characterized comparably. In a nutshell, the results of the present study may contribute to the development of the nanostructured Ti67IMP with improved surface properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anodic%20tio2%20nanotube" title="anodic tio2 nanotube">anodic tio2 nanotube</a>, <a href="https://publications.waset.org/abstracts/search?q=biomedical%20applications" title=" biomedical applications"> biomedical applications</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene%20oxide" title=" graphene oxide"> graphene oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=silver" title=" silver"> silver</a>, <a href="https://publications.waset.org/abstracts/search?q=spin%20coating" title=" spin coating"> spin coating</a> </p> <a href="https://publications.waset.org/abstracts/51938/synthesis-and-characterization-of-silvergraphene-oxide-co-decorated-tio2-nanotubular-arrays-for-biomedical-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51938.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">325</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Generation of ZnO-Au Nanocomposite in Water Using Pulsed Laser Irradiation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elmira%20Solati">Elmira Solati</a>, <a href="https://publications.waset.org/abstracts/search?q=Atousa%20Mehrani"> Atousa Mehrani</a>, <a href="https://publications.waset.org/abstracts/search?q=Davoud%20Dorranian"> Davoud Dorranian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Generation of ZnO-Au nanocomposite under laser irradiation of a mixture of the ZnO and Au colloidal suspensions are experimentally investigated. In this work, firstly ZnO and Au nanoparticles are prepared by pulsed laser ablation of the corresponding metals in water using the 1064 nm wavelength of Nd:YAG laser. In a second step, the produced ZnO and Au colloidal suspensions were mixed in different volumetric ratio and irradiated using the second harmonic of a Nd:YAG laser operating at 532 nm wavelength. The changes in the size of the nanostructure and optical properties of the ZnO-Au nanocomposite are studied as a function of the volumetric ratio of ZnO and Au colloidal suspensions. The crystalline structure of the ZnO-Au nanocomposites was analyzed by X-ray diffraction (XRD). The optical properties of the samples were examined at room temperature by a UV-Vis-NIR absorption spectrophotometer. Transmission electron microscopy (TEM) was done by placing a drop of the concentrated suspension on a carbon-coated copper grid. To further confirm the morphology of ZnO-Au nanocomposites, we performed Scanning electron microscopy (SEM) analysis. Room temperature photoluminescence (PL) of the ZnO-Au nanocomposites was measured to characterize the luminescence properties of the ZnO-Au nanocomposites. The ZnO-Au nanocomposites were characterized by Fourier transform infrared (FTIR) spectroscopy. The X-ray diffraction pattern shows that the ZnO-Au nanocomposites had the polycrystalline structure of Au. The behavior observed by images of transmission electron microscope reveals that soldering of Au and ZnO nanoparticles include their adhesion. The plasmon peak in ZnO-Au nanocomposites was red-shifted and broadened in comparison with pure Au nanoparticles. By using the Tauc’s equation, the band gap energy for ZnO-Au nanocomposites is calculated to be 3.15–3.27 eV. In this work, the formation of ZnO-Au nanocomposites shifts the FTIR peak of metal oxide bands to higher wavenumbers. PL spectra of the ZnO-Au nanocomposites show that several weak peaks in the ultraviolet region and several relatively strong peaks in the visible region. SEM image indicates that the morphology of ZnO-Au nanocomposites produced in water was spherical. The TEM images of ZnO-Au nanocomposites demonstrate that with increasing the volumetric ratio of Au colloidal suspension the adhesion increased. According to the size distribution graphs of ZnO-Au nanocomposites with increasing the volumetric ratio of Au colloidal suspension the amount of ZnO-Au nanocomposites with the smaller size is further. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Au%20nanoparticles" title="Au nanoparticles">Au nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=pulsed%20laser%20ablation" title=" pulsed laser ablation"> pulsed laser ablation</a>, <a href="https://publications.waset.org/abstracts/search?q=ZnO-Au%20nanocomposites" title=" ZnO-Au nanocomposites"> ZnO-Au nanocomposites</a>, <a href="https://publications.waset.org/abstracts/search?q=ZnO%20nanoparticles" title=" ZnO nanoparticles"> ZnO nanoparticles</a> </p> <a href="https://publications.waset.org/abstracts/36793/generation-of-zno-au-nanocomposite-in-water-using-pulsed-laser-irradiation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36793.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">344</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">12</span> Ligandless Extraction and Determination of Trace Amounts of Lead in Pomegranate, Zucchini and Lettuce Samples after Dispersive Liquid-Liquid Microextraction with Ultrasonic Bath and Optimization of Extraction Condition with RSM Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fariba%20Tadayon">Fariba Tadayon</a>, <a href="https://publications.waset.org/abstracts/search?q=Elmira%20Hassanlou"> Elmira Hassanlou</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Bagheri"> Hasan Bagheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Jafarian"> Mostafa Jafarian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heavy metals are released into water, plants, soil, and food by natural and human activities. Lead has toxic roles in the human body and may cause serious problems even in low concentrations, since it may have several adverse effects on human. Therefore, determination of lead in different samples is an important procedure in the studies of environmental pollution. In this work, an ultrasonic assisted-ionic liquid based-liquid-liquid microextraction (UA-IL-DLLME) procedure for the determination of lead in zucchini, pomegranate, and lettuce has been established and developed by using flame atomic absorption spectrometer (FAAS). For UA-IL-DLLME procedure, 10 mL of the sample solution containing Pb2+ was adjusted to pH=5 in a glass test tube with a conical bottom; then, 120 μL of 1-Hexyl-3-methylimidazolium hexafluoro phosphate (CMIM)(PF6) was rapidly injected into the sample solution with a microsyringe. After that, the resulting cloudy mixture was treated by ultrasonic for 5 min, then the separation of two phases was obtained by centrifugation for 5 min at 3000 rpm and IL-phase diluted with 1 cc ethanol, and the analytes were determined by FAAS. The effect of different experimental parameters in the extraction step including: ionic liquid volume, sonication time and pH was studied and optimized simultaneously by using Response Surface Methodology (RSM) employing a central composite design (CCD). The optimal conditions were determined to be an ionic liquid volume of 120 μL, sonication time of 5 min, and pH=5. The linear ranges of the calibration curve for the determination by FAAS of lead were 0.1-4 ppm with R2=0.992. Under optimized conditions, the limit of detection (LOD) for lead was 0.062 μg.mL-1, the enrichment factor (EF) was 93, and the relative standard deviation (RSD) for lead was calculated as 2.29%. The levels of lead for pomegranate, zucchini, and lettuce were calculated as 2.88 μg.g-1, 1.54 μg.g-1, 2.18 μg.g-1, respectively. Therefore, this method has been successfully applied for the analysis of the content of lead in different food samples by FAAS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dispersive%20liquid-liquid%20microextraction" title="Dispersive liquid-liquid microextraction">Dispersive liquid-liquid microextraction</a>, <a href="https://publications.waset.org/abstracts/search?q=Central%20composite%20design" title=" Central composite design"> Central composite design</a>, <a href="https://publications.waset.org/abstracts/search?q=Food%20samples" title=" Food samples"> Food samples</a>, <a href="https://publications.waset.org/abstracts/search?q=Flame%20atomic%20absorption%20spectrometry." title=" Flame atomic absorption spectrometry."> Flame atomic absorption spectrometry.</a> </p> <a href="https://publications.waset.org/abstracts/43911/ligandless-extraction-and-determination-of-trace-amounts-of-lead-in-pomegranate-zucchini-and-lettuce-samples-after-dispersive-liquid-liquid-microextraction-with-ultrasonic-bath-and-optimization-of-extraction-condition-with-rsm-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43911.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">283</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> Effects of Nutrient Source and Drying Methods on Physical and Phytochemical Criteria of Pot Marigold (Calendula offiCinalis L.)

Different nutrient sources (vermicompost, municipal waste compost, cattle manure, mushroom compost and control) which were applied in a field experiment for flower production and different drying methods including microwave (300, 600 and 900 W), oven (60, 70 and 80oC) and natural-shade drying in room temperature, were tested. Criteria such as drying kinetic, antioxidant activity, total flavonoid content, total phenolic compounds and total carotenoid of flowers were evaluated. Results indicated that organic inputs as nutrient source for flowers had no significant effects on quality criteria of pot marigold except of total flavonoid content, while drying methods significantly affected phytochemical criteria. Application of microwave 300, 600 and 900 W resulted in the highest amount of total flavonoid content, total phenolic compounds and antioxidant activity, respectively, while oven drying caused the lowest amount of phytochemical criteria. Also, interaction effect of nutrient source and drying method significantly affected antioxidant activity in which the highest amount of antioxidant activity was obtained in combination of vermicompost and microwave 900 W. In addition, application of vermicompost combined with oven drying at 60oC caused the lowest amount of antioxidant activity. Based on results of drying trend, microwave drying showed a faster drying rate than those oven and natural-shade drying in which by increasing microwave power and oven temperature, time of flower drying decreased whereas slope of moisture content reduction curve showed accelerated trend. <p class="card-text"><strong>Keywords:</strong> <a
