The involvement of phytochemicals in the Daucus carota extract in the reduction and stabilization of silver nanoparticles has been established using XRD and UV-vis studies. The UV-vis spectrum of the prepared silver nanoparticles showed surface plasmon absorbance peak at 450 nm. The obtained silver nanoparticles were almost spherical in shape with the average size of 15 nm. Crystalline nature of the nanoparticles was evident from bright spots in the SAED pattern and peaks in the XRD pattern. This new, simple and natural method for biosynthesis of silver nanoparticles offers a valuable contribution in the area of green synthesis and nanotechnology avoiding the presence of hazardous and toxic solvents and waste. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daucus%20carota" title="Daucus carota">Daucus carota</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20synthesis" title=" green synthesis"> green synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20nanoparticles" title=" silver nanoparticles"> silver nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20plasmon%20resonance" title=" surface plasmon resonance"> surface plasmon resonance</a> </p> <a href="https://publications.waset.org/abstracts/7588/synthesis-and-characterization-of-silver-nanoparticles-using-daucus-carota-extract" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7588.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">10</span> Physico-Chemical Characterization of the Essential Oil of Daucus carota</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nassima%20Behidj-Benyounes">Nassima Behidj-Benyounes</a>, <a href="https://publications.waset.org/abstracts/search?q=Thoraya%20Dahmene"> Thoraya Dahmene</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Benyounes%20Nadjiba%20Chebouti1and%20F%2FZohra%20Bissaad"> Khaled Benyounes Nadjiba Chebouti1and F/Zohra Bissaad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Essential oils have a significant antimicrobial activity.

This work aims to study the insecticidal effect of the essential oil of three plants: Phoenician juniper Juniperus phoenicea; the Niaouli Melaleuca quinquenervia and the wild carrot Daucus carota L, on the chickpea weevil Callosobruchus maculatus F, which is known as a formidable pest of legumes. Essential oils are obtained by hydrodistillation. The study carried out in the laboratory concerning the insecticidal activity of these essential oils by contact and inhalation effect on C.maculatus gave important results, especially for the essential oil of Juniperus phoenicea for the contact test; and for the inhalation test, the essential oil of Melaleuca quinquenervia shows remarkable insecticidal activity compared to the other two oils. The results of these tests showed a very interesting action.

In this study, Leaf samples were taken from the carrot plants grown under drought stress conditions during the harvesting period. The plants were irrigated in three irrigation interval (4, 6 and 8 days) and Irrigation water regime was set up in pots. The changes in activities of antioxidant enzymes such as glutathione reductase (GR), glutathione s-transferase (GST), superoxide dismutase (SOD)) in leaves of black carrot were investigated. The activities of antioxidant enzymes (GR, GST, SOD) were varied significantly with irrigation intervals. The highest value of GR, GST and SOD were determined in the irrigation interval of 6 days. All antioxidant activity values were decreased in 8 days of irrigation interval. As a result of the study, it has been suggested that optimum irrigation intervals for plants can be used in antioxidant enzymes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20enzyme" title="antioxidant enzyme">antioxidant enzyme</a>, <a href="https://publications.waset.org/abstracts/search?q=carrot" title=" carrot"> carrot</a>, <a href="https://publications.waset.org/abstracts/search?q=drought" title=" drought"> drought</a>, <a href="https://publications.waset.org/abstracts/search?q=irrigation%20interval" title=" irrigation interval"> irrigation interval</a> </p> <a href="https://publications.waset.org/abstracts/96989/effects-of-irrigation-intervals-on-antioxidant-enzyme-activity-in-black-carrot-leaves-daucus-carota-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96989.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">221</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">5</span> Evaluation of Storage Stability and Quality Parameters in Biscuit Made from Blends of Wheat, Cassava (Manihot esculenta) and Carrot (Daucus carota) Flour</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aminat.%20O%20Adelekan">Aminat.

This study investigates some quality parameters in biscuits made from blends of wheat, cassava and carrot flour. The values of result of samples increased with increasing percentage substitution of cassava and carrot flour in some quality parameter like fiber, ash, gluten content, and carbohydrate. The protein content reduced significantly (P < 0.05) with increasing percentage substitution of cassava and carrot flour which ranged from 14.80% to 11.80% compared with the control sample which had 15.60%. There was a recorded significant increase (P < 0.05) in some mineral composition such as calcium, magnesium, sodium, iron, phosphorus, and vitamin A and C composition as the percentage substitution of cassava and carrot flour increased. During storage stability test, samples stored in the fridge and freezer were found to be the best storage location to preserve the sensory attributes and inhibit microbial growth when compared with storage under the sun and on the shelf. Biscuit made with blends of wheat, cassava and carrot flour can therefore serve as an alternative to biscuits made from 100% wheat flour, as they are richer in vitamin A, vitamin C, carbohydrate, dietary fiber and some essential minerals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biscuit" title="biscuit">biscuit</a>, <a href="https://publications.waset.org/abstracts/search?q=carrot" title=" carrot"> carrot</a>, <a href="https://publications.waset.org/abstracts/search?q=flour%20blends" title=" flour blends"> flour blends</a>, <a href="https://publications.waset.org/abstracts/search?q=storage" title=" storage"> storage</a> </p> <a href="https://publications.waset.org/abstracts/107445/evaluation-of-storage-stability-and-quality-parameters-in-biscuit-made-from-blends-of-wheat-cassava-manihot-esculenta-and-carrot-daucus-carota-flour" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107445.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">138</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">4</span> Effect of Poultry Manure and Nitrogen, Phosphorus, and Potassium (15:15:15) Soil Amendment on Growth and Yield of Carrot (Daucus carota)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benjamin%20Osae%20Agyei">Benjamin Osae Agyei</a>, <a href="https://publications.waset.org/abstracts/search?q=Hypolite%20Bayor"> Hypolite Bayor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This present experiment was carried out during the 2012 cropping season, at the Farming for the Future Experimental Field of the University for Development Studies, Nyankpala Campus in the Northern Region of Ghana.

Data were collected on plant height, number of leaves per plant, canopy spread, root diameter, root weight, and root length. Microsoft Excel and Genstat Statistical Package (9<sup>th</sup> edition) were used for the data analysis. The treatment means were compared by using Least Significant Difference at 10%. Generally, the results showed that there were no significant differences (P>0.1) among the treatments with respect to number of leaves per plant, root diameter, root weight, and root length. However, significant differences occurred among plant heights and canopy spreads. Plant height treated with 40 t/ha PM at the fourth week after planting and canopy spread at eight weeks after planting and ten weeks after planting by 70 t/ha PM and 20 t/ha PM respectively showed significant difference (P<0.1). The study recommended that any of the amended treatments can be applied at their recommended rates to plots for carrot production, since there were no significant differences among the treatments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=poultry%20manure" title="poultry manure">poultry manure</a>, <a href="https://publications.waset.org/abstracts/search?q=N.P.K." title=" N.P.K."> N.P.K.</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20amendment" title=" soil amendment"> soil amendment</a>, <a href="https://publications.waset.org/abstracts/search?q=growth" title=" growth"> growth</a>, <a href="https://publications.waset.org/abstracts/search?q=yield" title=" yield"> yield</a>, <a href="https://publications.waset.org/abstracts/search?q=carrot" title=" carrot"> carrot</a> </p> <a href="https://publications.waset.org/abstracts/58880/effect-of-poultry-manure-and-nitrogen-phosphorus-and-potassium-151515-soil-amendment-on-growth-and-yield-of-carrot-daucus-carota" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58880.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">471</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">3</span> Natural Antioxidant Changes in Fresh and Dried Spices and Vegetables</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liga%20Priecina">Liga Priecina</a>, <a href="https://publications.waset.org/abstracts/search?q=Daina%20Karklina"> Daina Karklina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Antioxidants are became the most analyzed substances in last decades. Antioxidants act as in activator for free radicals. Spices and vegetables are one of major antioxidant sources. Most common antioxidants in vegetables and spices are vitamin C, E, phenolic compounds, carotenoids. Therefore, it is important to get some view about antioxidant changes in spices and vegetables during processing. In this article was analyzed nine fresh and dried spices and vegetables- celery (Apium graveolens), parsley (Petroselinum crispum), dill (Anethum graveolens), leek (Allium ampeloprasum L.), garlic (Allium sativum L.), onion (Allium cepa), celery root (Apium graveolens var. rapaceum), pumpkin (Curcubica maxima), carrot (Daucus carota)- grown in Latvia 2013. Total carotenoids and phenolic compounds and their antiradical scavenging activity were determined for all samples. Dry matter content was calculated from moisture content. After drying process carotenoid content significantly decreases in all analyzed samples, except one -carotenoid content increases in parsley. Phenolic composition was different and depends on sample – fresh or dried. Total phenolic, flavonoid and phenolic acid content increases in dried spices. Flavan-3-ol content is not detected in fresh spice samples. For dried vegetables- phenolic acid content decreases significantly, but increases flavan-3-ols content. The higher antiradical scavenging activity was observed in samples with higher flavonoid and phenolic acid content. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antiradical%20scavenging%20activity" title="antiradical scavenging activity">antiradical scavenging activity</a>, <a href="https://publications.waset.org/abstracts/search?q=carotenoids" title=" carotenoids"> carotenoids</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20compounds" title=" phenolic compounds"> phenolic compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=spices" title=" spices"> spices</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetables" title=" vegetables"> vegetables</a> </p> <a href="https://publications.waset.org/abstracts/8667/natural-antioxidant-changes-in-fresh-and-dried-spices-and-vegetables" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8667.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">262</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">2</span> Extraction and Encapsulation of Carotenoids from Carrot</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gordana%20%C4%86etkovi%C4%87">Gordana Ćetković</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanja%20Podunavac-Kuzmanovi%C4%87"> Sanja Podunavac-Kuzmanović</a>, <a href="https://publications.waset.org/abstracts/search?q=Jasna%20%C4%8Canadanovi%C4%87-Brunet"> Jasna Čanadanović-Brunet</a>, <a href="https://publications.waset.org/abstracts/search?q=Vesna%20Tumbas%20%C5%A0aponjac"> Vesna Tumbas Šaponjac</a>, <a href="https://publications.waset.org/abstracts/search?q=Vanja%20%C5%A0eregelj"> Vanja Šeregelj</a>, <a href="https://publications.waset.org/abstracts/search?q=Jelena%20Vuli%C4%87"> Jelena Vulić</a>, <a href="https://publications.waset.org/abstracts/search?q=Sla%C4%91ana%20Staj%C4%8Di%C4%87"> Slađana Stajčić</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The color of food is one of the decisive factors for consumers. Potential toxicity of artificial food colorants has led to the consumers' preference for natural products over products with artificial colors. Natural pigments have many bioactive functions, such as antioxidant, provitamin and many other. Having this in mind, the acceptability of natural colorants by the consumers is much higher. Being present in all photosynthetic plant tissues carotenoids are probably most widespread pigments in nature. Carrot (Daucus carota) is a good source of functional food components. Carrot is especially rich in carotenoids, mainly α- and β-carotene and lutein. For this study, carrot was extracted using classical extraction with hexane and ethyl acetate, as well as supercritical CO₂ extraction. The extraction efficiency was evaluated by estimation of carotenoid yield determined spectrophotometrically. Classical extraction using hexane (18.27 mg β-carotene/100 g DM) was the most efficient method for isolation of carotenoids, compared to ethyl acetate classical extraction (15.73 mg β-carotene/100 g DM) and supercritical CO₂ extraction (0.19 mg β-carotene/100 g DM). Three carrot extracts were tested in terms of antioxidant activity using DPPH and reducing power assay as well. Surprisingly, ethyl acetate extract had the best antioxidant activity on DPPH radicals (AADPPH=120.07 μmol TE/100 g) while hexane extract showed the best reducing power (RP=1494.97 μmol TE/100 g). Hexane extract was chosen as the most potent source of carotenoids and was encapsulated in whey protein by freeze-drying. Carotenoid encapsulation efficiency was found to be high (89.33%). Based on our results it can be concluded that carotenoids from carrot can be efficiently extracted using hexane and classical extraction method. This extract has the potential to be applied in encapsulated form due to high encapsulation efficiency and coloring capacity. Therefore it can be used for dietary supplements development and food fortification. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carotenoids" title="carotenoids">carotenoids</a>, <a href="https://publications.waset.org/abstracts/search?q=carrot" title=" carrot"> carrot</a>, <a href="https://publications.waset.org/abstracts/search?q=extraction" title=" extraction"> extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=encapsulation" title=" encapsulation"> encapsulation</a> </p> <a href="https://publications.waset.org/abstracts/76718/extraction-and-encapsulation-of-carotenoids-from-carrot" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76718.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">271</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">1</span> Detection of Mustard Traces in Food by an Official Food Safety Laboratory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Clara%20Tramuta">Clara Tramuta</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucia%20Decastelli"> Lucia Decastelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisa%20Barcucci"> Elisa Barcucci</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Fragassi"> Sandra Fragassi</a>, <a href="https://publications.waset.org/abstracts/search?q=Samantha%20Lupi"> Samantha Lupi</a>, <a href="https://publications.waset.org/abstracts/search?q=Enrico%20Arletti"> Enrico Arletti</a>, <a href="https://publications.waset.org/abstracts/search?q=Melissa%20Bizzarri"> Melissa Bizzarri</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Manila%20Bianchi"> Daniela Manila Bianchi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introdution: Food allergies occurs, in the Western World, 2% of adults and up to 8% of children. The protection of allergic consumers is guaranted, in Eurrope, by Regulation (EU) No 1169/2011 of the European Parliament which governs the consumer's right to information and identifies 14 food allergens to be mandatory indicated on the label. Among these, mustard is a popular spice added to enhance the flavour and taste of foods. It is frequently present as an ingredient in spice blends, marinades, salad dressings, sausages, and other products. Hypersensitivity to mustard is a public health problem since the ingestion of even low amounts can trigger severe allergic reactions. In order to protect the allergic consumer, high performance methods are required for the detection of allergenic ingredients. Food safety laboratories rely on validated methods that detect hidden allergens in food to ensure the safety and health of allergic consumers. Here we present the test results for the validation and accreditation of a Real time PCR assay (RT-PCR: SPECIALfinder MC Mustard, Generon), for the detection of mustard traces in food. Materials and Methods. The method was tested on five classes of food matrices: bakery and pastry products (chocolate cookies), meats (ragù), ready-to-eat (mixed salad), dairy products (yogurt), grains, and milling products (rice and barley flour). Blank samples were spiked starting with the mustard samples (Sinapis Alba), lyophilized and stored at -18 °C, at a concentration of 1000 ppm. Serial dilutions were then prepared to a final concentration of 0.5 ppm, using the DNA extracted by ION Force FAST (Generon) from the blank samples. The Real Time PCR reaction was performed by RT-PCR SPECIALfinder MC Mustard (Generon), using CFX96 System (BioRad). Results. Real Time PCR showed a limit of detection (LOD) of 0.5 ppm in grains and milling products, ready-to-eat, meats, bakery, pastry products, and dairy products (range Ct 25-34). To determine the exclusivity parameter of the method, the ragù matrix was contaminated with Prunus dulcis (almonds), peanut (Arachis hypogaea), Glycine max (soy), Apium graveolens (celery), Allium cepa (onion), Pisum sativum (peas), Daucus carota (carrots), and Theobroma cacao (cocoa) and no cross-reactions were observed. Discussion. In terms of sensitivity, the Real Time PCR confirmed, even in complex matrix, a LOD of 0.5 ppm in five classes of food matrices tested; these values are compatible with the current regulatory situation that does not consider, at international level, to establish a quantitative criterion for the allergen considered in this study. The Real Time PCR SPECIALfinder kit for the detection of mustard proved to be easy to use and particularly appreciated for the rapid response times considering that the amplification and detection phase has a duration of less than 50 minutes. Method accuracy was rated satisfactory for sensitivity (100%) and specificity (100%) and was fully validated and accreditated. It was found adequate for the needs of the laboratory as it met the purpose for which it was applied. This study was funded in part within a project of the Italian Ministry of Health (IZS PLV 02/19 RC). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=allergens" title="allergens">allergens</a>, <a href="https://publications.waset.org/abstracts/search?q=food" title=" food"> food</a>, <a href="https://publications.waset.org/abstracts/search?q=mustard" title=" mustard"> mustard</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20time%20PCR" title=" real time PCR"> real time PCR</a> </p> <a href="https://publications.waset.org/abstracts/144177/detection-of-mustard-traces-in-food-by-an-official-food-safety-laboratory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144177.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">166</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response); });*/ jQuery.get({ url: "https://publications.waset.org/xhr/user-menu", cache: false }).then(function(response){ jQuery('#mainNavMenu').append(response); }); }); </script> </body> </html>
