</p> <p class="card-text"><strong>Abstract:</strong></p> Insect’s innate immunity depends on a variety of defense responses for the recognition of invading pathogens. Pathogen recognition involves particular proteins known as pattern recognition receptors (PRRs). These PRRs interact with pathogen-associated molecular patterns (PAMPs) present on the surface of pathogens to distinguish between self and non-self. C-type lectins (CTLs) belong to a superfamily of PPRs which involved in insect immunity and defense mechanism. Rhynchophorus ferrugineus Olivier is a devastating pest of Palm cultivations in China. Although studies on R. ferrugineus immune mechanism and host defense have conducted, however, the role of CTL in immune responses of R. ferrugineus remains elusive. Here, we report RfCTL, which is a secreted protein containing a single-CRD domain. The open reading frame (ORF) of CTL is 226 bp, which encodes a putative protein of 168 amino acids. Transcript expression analysis revealed that RfCTL highly expressed in immune-related tissues, i.e., hemolymph and fat body. The abundance of RfCTL in the gut and fat body dramatically increased upon Staphylococcus aureus and Escherichia coli bacterial challenges, suggesting a role in defense against gram-positive and gram-negative bacterial infection. Taken together, we inferred that RfCTL might be involved in the immune defense of R. ferrugineus and established a solid foundation for future studies on R. ferrugineus CTL domain proteins for better understanding of insect immunity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biological%20invasion" title="biological invasion">biological invasion</a>, <a href="https://publications.waset.org/abstracts/search?q=c-type%20lectin" title=" c-type lectin"> c-type lectin</a>, <a href="https://publications.waset.org/abstracts/search?q=insect%20immunity" title=" insect immunity"> insect immunity</a>, <a href="https://publications.waset.org/abstracts/search?q=Rhynchophorus%20ferrugineus%20Oliver" title=" Rhynchophorus ferrugineus Oliver"> Rhynchophorus ferrugineus Oliver</a> </p> <a href="https://publications.waset.org/abstracts/118350/molecular-characterization-and-identification-of-c-type-lectin-in-red-palm-weevil-rhynchophorus-ferrugineus-oliver" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118350.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">157</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">150</span> Efficacy of Different Plant Extracts against Brevicoryne brassicae and Their Effects on Pollinators</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hafiza%20Javaria%20Ashraf">Hafiza Javaria Ashraf</a>, <a href="https://publications.waset.org/abstracts/search?q=Asim%20Abbasi"> Asim Abbasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Hussnain%20Babar"> Muhammad Hussnain Babar</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Sufyan"> Muhammad Sufyan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Brevicoryne brassicae (Aphid) is not only the major biotic constraint of rapeseed crop but also transmits 20 different viral pathogens that cause diseases in crucifers. Aphids cause major losses to rapeseed by stunting growth and yield, with real damage being contamination of harvested heads. The misuse of pesticides has led to tremendous economic losses and hazards to human health and environmental pollution. Thus, newer approaches for pest control are continuously being sought. The naturally occurring, biologically active plant-based products seem to have a prominent role in the development of future commercial pesticides not only for increased productivity but their eco-friendly nature. The present experiment was carried out in Research Area of Ayub Agriculture Research Institute, Faisalabad to check the efficacy of different botanicals against rapeseed aphid. The tested botanicals were, neem seed extract, neem leaf extract, dathora seed extract, kaner leaf extract and aak leaf extract. Insecticide, advantage 20 EC served as the positive control in the experiment. Data was recorded before and after 1, 3 and 7 days of treatment application. The results of the experiment revealed that neem seed extract exhibited maximum mortality (48.42%) followed by dathora (45.54%) and kaner leaf extract (40.29%) after 7 days of treatment application. However minimum mortality i.e. 26.64% was observed in case of aak leaf extract. Advantage encountered maximum mortality i.e. 86.14%. All treatments caused maximum mortality after 7 days of treatment application. In case of pollinators maximum population reduction was observed in case of insecticide (74.29%) while minimum reduction was observed in neem leaf extract (11.57%). Hence it was concluded that unlike insecticides, plant based products can be a better option for regulating pests and conserving beneficial insect fauna. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aphid" title="Aphid">Aphid</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality" title=" mortality"> mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20based" title=" plant based"> plant based</a>, <a href="https://publications.waset.org/abstracts/search?q=pollinators" title=" pollinators"> pollinators</a> </p> <a href="https://publications.waset.org/abstracts/80251/efficacy-of-different-plant-extracts-against-brevicoryne-brassicae-and-their-effects-on-pollinators" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80251.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">226</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">149</span> A Review on Biological Control of Mosquito Vectors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asim%20Abbasi">Asim Abbasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Sufyan"> Muhammad Sufyan</a>, <a href="https://publications.waset.org/abstracts/search?q=Iqra"> Iqra</a>, <a href="https://publications.waset.org/abstracts/search?q=Hafiza%20Javaria%20Ashraf"> Hafiza Javaria Ashraf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The share of vector-borne diseases (VBDs) in the global burden of infectious diseases is almost 17%. The advent of new drugs and latest research in medical science helped mankind to compete with these lethal diseases but still diseases transmitted by different mosquito species, including filariasis, malaria, viral encephalitis and dengue are serious threats for people living in disease endemic areas. Injudicious and repeated use of pesticides posed selection pressure on mosquitoes leading to development of resistance. Hence biological control agents are under serious consideration of scientific community to be used in vector control programmes. Fish have a history of predating immature stages of different aquatic insects including mosquitoes. The noteworthy examples in Africa and Asia includes, Aphanius discolour and a fish in the Panchax group. Moreover, common mosquito fish, Gambusia affinis predates mostly on temporary water mosquitoes like anopheline as compared to permanent water breeders like culicines. Mosquitoes belonging to genus Toxorhynchites have a worldwide distribution and are mostly associated with the predation of other mosquito larvae habituating with them in natural and artificial water containers. These species are harmless to humans as their adults do not suck human blood but feeds on floral nectar. However, their activity is mostly temperature dependent as Toxorhynchites brevipalpis consume 359 Aedes aegypti larvae at 30-32 ºC in contrast to 154 larvae at 20-26 ºC. Although many bacterial species were isolated from mosquito cadavers but those belonging to genus Bacillus are found highly pathogenic against them. The successful species of this genus include Bacillus thuringiensis and Bacillus sphaericus. The prime targets of B. thuringiensis are mostly the immatures of genus Aedes, Culex, Anopheles and Psorophora while B. sphaericus is specifically toxic against species of Culex, Psorophora and Culiseta. The entomopathogenic nematodes belonging to family, mermithidae are also pathogenic to different mosquito species. Eighty different species of mosquitoes including Anopheles, Aedes and Culex proved to be highly vulnerable to the attack of two mermithid species, Romanomermis culicivorax and R. iyengari. Cytoplasmic polyhedrosis virus was the first described pathogenic virus, isolated from the cadavers of mosquito specie, Culex tarsalis. Other viruses which are pathogenic to culicine includes, iridoviruses, cytopolyhedrosis viruses, entomopoxviruses and parvoviruses. Protozoa species belonging to division microsporidia are the common pathogenic protozoans in mosquito populations which kill their host by the chronic effects of parasitism. Moreover, due to their wide prevalence in anopheline mosquitoes and transversal and horizontal transmission from infected to healthy host, microsporidia of the genera Nosema and Amblyospora have received much attention in various mosquito control programmes. Fungal based mycopesticides are used in biological control of insect pests with 47 species reported virulent against different stages of mosquitoes. These include both aquatic fungi i.e. species of Coelomomyces, Lagenidium giganteum and Culicinomyces clavosporus, and the terrestrial fungi Metarhizium anisopliae and Beauveria bassiana. Hence, it was concluded that the integrated use of all these biological control agents can be a healthy contribution in mosquito control programmes and become a dire need of the time to avoid repeated use of pesticides. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entomopathogenic%20nematodes" title="entomopathogenic nematodes">entomopathogenic nematodes</a>, <a href="https://publications.waset.org/abstracts/search?q=protozoa" title=" protozoa"> protozoa</a>, <a href="https://publications.waset.org/abstracts/search?q=Toxorhynchites" title=" Toxorhynchites"> Toxorhynchites</a>, <a href="https://publications.waset.org/abstracts/search?q=vector-borne" title=" vector-borne"> vector-borne</a> </p> <a href="https://publications.waset.org/abstracts/80088/a-review-on-biological-control-of-mosquito-vectors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80088.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">267</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">148</span> Transmogrification of the Danse Macabre Image: Capturing the Journey towards Creativity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Javaria%20Farooqui">Javaria Farooqui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study, “Transmogrification of the Danse Macabre Image: Capturing the Journey towards Creativity,” traces the evolution of the concept of Danse Macabre.

Devices are able to communicate directly using the wireless spectrum in a peer-to-peer fashion, and route messages through intermediate nodes, however, the nature of wireless shared communication and mobile devices result in many routing and security challenges which must be addressed before deploying a MANET. In this paper, we investigate the range of MANET routing protocols available and discuss the functionalities of several ranging from early protocols such as DSDV to more advanced such as MAODV, our protocol study focuses upon works by Perkins in developing and improving MANET routing. A range of literature relating to the field of MANET routing was identified and reviewed, we also reviewed literature on the topic of securing AODV based MANETs as this may be the most popular MANET protocol. The literature review identified a number of trends within research papers such as exclusive use of the random waypoint mobility model, excluding key metrics from simulation results and not comparing protocol performance against available alternatives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=protocol" title="protocol">protocol</a>, <a href="https://publications.waset.org/abstracts/search?q=MANET" title=" MANET"> MANET</a>, <a href="https://publications.waset.org/abstracts/search?q=ad-Hoc" title=" ad-Hoc"> ad-Hoc</a>, <a href="https://publications.waset.org/abstracts/search?q=communication" title=" communication"> communication</a> </p> <a href="https://publications.waset.org/abstracts/43620/a-review-of-routing-protocols-for-mobile-ad-hoc-networks-manet" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43620.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">261</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">145</span> Comparative Analysis of Climate Mitigation Strategies Adopted by Farmers of Pakistan and the USA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gulfam%20Hasan">Gulfam Hasan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ijaz%20Ashraf"> Ijaz Ashraf</a>, <a href="https://publications.waset.org/abstracts/search?q=Saleem%20Ashraf"> Saleem Ashraf</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Rafay%20Muzammil"> Muhammad Rafay Muzammil</a>, <a href="https://publications.waset.org/abstracts/search?q=Salman%20Asghar"> Salman Asghar</a>, <a href="https://publications.waset.org/abstracts/search?q=Shafiq-Ur-Rehman%20Zia"> Shafiq-Ur-Rehman Zia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The word “climate change” has become the most popular term when anyone observes any uncertain climate variation in their respective region. Asian countries are more prone to the impact of this phenomenon, and Pakistan is the leading affected country. Last few years, governments all over the world have been trying to cater to this issue for the best entrust of their population, especially agriculture. Now the farmers in Pakistan are fully aware of the term “climate change” and are more concerned about its solutions. On the other hand, developed countries like the USA are setting a benchmark for developing countries in every sphere of life. Based on cultural and other variations, the research was carried out to identify the behavior of farmers regarding the same issue. Cross-sectional survey research was designed for an in-depth study of relevant research questions. Face-to-face interviews were conducted in Pakistan, while virtual and face-to-face interviews were conducted in the Indiana State of the USA. The results of the present study and the responses of farmers were very interesting. The common climate change mitigation strategies suggested by farmers of both countries were less use of motor vehicles (replacement with bicycles in the circle of 10 Km), less dependency on chemical fertilizers (increased use of Manure, Bio-fertilizer, Compost), and plantation of the tree. The difference of opinion was in less government interest, lack of farmers’ education, political instability (views of Pakistani farmers), awareness of local communities, self-satisfaction, and economic disparities (views of USA farmers). Based on the given evidence, it was recommended that there is a dire need to address the climate change issue all over the world without discrimination of race, color, region, or religion. Because it will affect not only agriculture but also the real effect will be on HUMANITY. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=mitigation%20strategies" title=" mitigation strategies"> mitigation strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=forests" title=" forests"> forests</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title=" biodiversity"> biodiversity</a> </p> <a href="https://publications.waset.org/abstracts/162155/comparative-analysis-of-climate-mitigation-strategies-adopted-by-farmers-of-pakistan-and-the-usa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162155.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">125</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">144</span> Optimization of Ultrasound Assisted Extraction and Characterization of Functional Properties of Dietary Fiber from Oat Cultivar S2000</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Suhail%20Ibrahim">Muhammad Suhail Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Nadeem"> Muhammad Nadeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Waseem%20Khalid"> Waseem Khalid</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammara%20Ainee"> Ammara Ainee</a>, <a href="https://publications.waset.org/abstracts/search?q=Taleeha%20Roheen"> Taleeha Roheen</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadaf%20Javaria"> Sadaf Javaria</a>, <a href="https://publications.waset.org/abstracts/search?q=Aftab%20Ahmed"> Aftab Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Hira%20Fatima"> Hira Fatima</a>, <a href="https://publications.waset.org/abstracts/search?q=Mian%20Nadeem%20Riaz"> Mian Nadeem Riaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Zubair%20Khalid"> Muhammad Zubair Khalid</a>, <a href="https://publications.waset.org/abstracts/search?q=Isam%20A.%20Mohamed%20Ahmed%20J"> Isam A.

Extraction (variables time, temperature and amplitude) was optimized by using response surface methodology (RSM) conducted by Box Behnken Design (BBD). The effect of time, temperature and amplitude were studied at three levels. It was observed that time and temperature exerted more impact on extraction efficiency as compared to amplitude. The highest yield of total dietary fiber (TDF), soluble dietary fiber (SDF) and In-soluble dietary fiber (IDF) fractions were observed under ultrasound processing for 20 min at 40 ◦C with 80% amplitude. Characterization of extracted dietary fiber showed that it had better crystallinity, thermal properties and good fibrous structure. It also showed better functional properties as compared to traditionally extracted dietary fiber. Furthermore, dietary fibers from oats may offer high-value utilization and the expansion of comprehensive utilization in functional food and nutraceutical development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extraction" title="extraction">extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonication" title=" ultrasonication"> ultrasonication</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20methodology" title=" response surface methodology"> response surface methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=box%20behnken%20design" title=" box behnken design"> box behnken design</a> </p> <a href="https://publications.waset.org/abstracts/187067/optimization-of-ultrasound-assisted-extraction-and-characterization-of-functional-properties-of-dietary-fiber-from-oat-cultivar-s2000" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187067.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">50</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">143</span> First Record of Eotragus noyei from the Middle Siwalik Dhok Pathan Formation of Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdul%20M.%20Khan">Abdul M.

The sample comprises maxillary and mandibular fragments along with isolated upper and lower teeth. The morphometric analysis of the specimens led us to recognize the sample as belonging to Eotragus noyei, which has been considered as the smallest and the oldest bovid in the Siwaliks. Eotragus noyei is characterized by brachydont teeth, finely rugose enamel, more inclined buccal walls of the molars and small lingual cingula. The inclination of the metaconal area has caused rotation of the metastyle in relation to the antero-posterior tooth axis and thus situated more lingually. The protocone in second upper premolar is well developed and situated posteriorly and also has an anterior lingual constriction. The metaconule in the third upper molar is smaller than the protocone. The dentition in Eotragus noyei is smaller in size as compared to Eotragus sansaniensis and Eotragus lampangensis. In Eotragus noyei the buccal walls in molars are more inclined while in Eotragus sansaniensis they are less inclined. The genus Eotragus has been reported previously in the Lower and Middle Siwaliks of Pakistan; however, the recognition of the present sample as Eotragus noyei has extended the range of this species from Lower to the Middle Siwaliks of Pakistan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boselaphini" title="Boselaphini">Boselaphini</a>, <a href="https://publications.waset.org/abstracts/search?q=Chakwal" title=" Chakwal"> Chakwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Dhok%20Pathan" title=" Dhok Pathan"> Dhok Pathan</a>, <a href="https://publications.waset.org/abstracts/search?q=late%20miocene" title=" late miocene"> late miocene</a> </p> <a href="https://publications.waset.org/abstracts/57627/first-record-of-eotragus-noyei-from-the-middle-siwalik-dhok-pathan-formation-of-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57627.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">292</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">142</span> Sustainable Renovation of Cultural Buildings Case Study: Red Bay National Historic Site, Canada </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Richard%20Briginshaw">Richard Briginshaw</a>, <a href="https://publications.waset.org/abstracts/search?q=Hana%20Alaojeli"> Hana Alaojeli</a>, <a href="https://publications.waset.org/abstracts/search?q=Javaria%20Ahmad"> Javaria Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamza%20Gaffar"> Hamza Gaffar</a>, <a href="https://publications.waset.org/abstracts/search?q=Nourtan%20Murad"> Nourtan Murad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sustainable renovations to cultural buildings and sites require a high level of competency in the sometimes conflicting areas of social/historical demands, environmental concerns, and the programmatic and technical requirements of the project. A detailed analysis of the existing site, building and client program are critical to reveal both challenges and opportunities. This forms the starting point for the design process – empirical explorations that search for a balanced and inspired architectural solution to the project. The Red Bay National Historic Site on the Labrador Coast of eastern Canada is a challenging project to explore and resolve these ideas. Originally the site of a 16ᵗʰ century whaling station occupied by Basque sailors from France and Spain, visitors now experience this history at the interpretive center, along with the unique geography, climate, local culture and vernacular architecture of the area. Working with our client, Parks Canada, the project called for significant alterations and expansion to the existing facility due to an increase in the number of annual visitors. Sustainable aspects of the design are focused on sensitive site development, passive energy strategies such as building orientation and building envelope efficiency, active renewable energy systems, carefully considered material selections, water efficiency, and interiors that respond to human comfort and a unique visitor experience. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainability" title="sustainability">sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=renovations%20and%20expansion" title=" renovations and expansion"> renovations and expansion</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20project" title=" cultural project"> cultural project</a>, <a href="https://publications.waset.org/abstracts/search?q=architectural%20design" title=" architectural design"> architectural design</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20building" title=" green building"> green building</a> </p> <a href="https://publications.waset.org/abstracts/88439/sustainable-renovation-of-cultural-buildings-case-study-red-bay-national-historic-site-canada" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88439.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">141</span> Reproductive Traits for Holstein Cattle </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20M.%20Ward">Ashraf M.

The overall means and standard errors for AFC and CI were 39.4 ± 7.2 months and 487.5 ± 151.6 days respectively. The respective heritability estimates were 0.091 ± 0.05 and 0.044 ± 0.032, while the repeatability estimate for CI was 0.096 ± 0.001. The genetic trends for CI and AFC were -0.6 d/yr and -0.01 mo/yr respectively and were both significant (P < 0.001), indicating a decrease in mean breeding value over the study period. Phenotypic trends were -0.31 mo/yr and -0.35 d/yr for AFC and CI respectively though non-significant (P > 0.05). The low heritability for CI and AFC indicated that temporary environmental influences were much greater than genetic influences or permanent environmental influences on these traits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Holstein" title="Holstein">Holstein</a>, <a href="https://publications.waset.org/abstracts/search?q=reproductive" title=" reproductive"> reproductive</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20parameters" title=" genetic parameters"> genetic parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=heritability" title=" heritability "> heritability </a> </p> <a href="https://publications.waset.org/abstracts/18509/reproductive-traits-for-holstein-cattle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18509.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">721</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">140</span> Dentofacial-Targeted Bullying: A Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mai%20Ashraf%20Talaat">Mai Ashraf Talaat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bullying is an aggressive behavior and a serious issue that should be addressed by everyone and should be avoided at all costs. It is very common among adolescents and schoolchildren and the effects can be devastating and long-lasting. Students are most commonly bullied about physical appearance, race, gender, disability, ethnicity, religion, and sexual orientation. Appearance-targeted bullying is a form of bullying that targets an aspect of a person's appearance, which includes facial and dental features. Deviation from accepted dentofacial aesthetics leads to elevated incidences of bullying in schoolchildren. The aim of this review article is to assess the prevalence of bullying due to dentofacial characteristics and evaluate the importance of dentofacial appearance on perceived social attractiveness based on multiple studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dentofacial%20features" title="dentofacial features">dentofacial features</a>, <a href="https://publications.waset.org/abstracts/search?q=orthodontics" title=" orthodontics"> orthodontics</a>, <a href="https://publications.waset.org/abstracts/search?q=malocclusion" title=" malocclusion"> malocclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=adolescents" title=" adolescents"> adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=bullying" title=" bullying"> bullying</a> </p> <a href="https://publications.waset.org/abstracts/166879/dentofacial-targeted-bullying-a-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166879.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">79</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">139</span> The Effects of Integrating Knowledge Management and e-Learning: Productive Work and Learning Coverage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20Ibrahim%20Awad">Ashraf Ibrahim Awad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is important to formulate suitable learning environments ca-pable to be customized according to value perceptions of the university. In this paper, light is shed on the concepts of integration between knowledge management (KM), and e-learning (EL) in the higher education sector of the economy in Abu Dhabi Emirate, United Arab Emirates (UAE). A discussion on and how KM and EL can be integrated and leveraged for effective education and training is presented. The results are derived from the literature and interviews with 16 of the academics in eight universities in the Emirate. The conclusion is that KM and EL have much to offer each other, but this is not yet reflected at the implementation level, and their boundaries are not always clear. Interviews have shown that both concepts perceived to be closely related and, responsibilities for these initiatives are practiced by different departments or units. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knowledge%20management" title="knowledge management">knowledge management</a>, <a href="https://publications.waset.org/abstracts/search?q=e-learning" title=" e-learning"> e-learning</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20integration" title=" learning integration"> learning integration</a>, <a href="https://publications.waset.org/abstracts/search?q=universities" title=" universities"> universities</a>, <a href="https://publications.waset.org/abstracts/search?q=UAE" title=" UAE"> UAE</a> </p> <a href="https://publications.waset.org/abstracts/34904/the-effects-of-integrating-knowledge-management-and-e-learning-productive-work-and-learning-coverage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34904.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">507</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">138</span> Social Information Seeking: Studying the Effect of Question Type on Responses in Social Q&A Sites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arshia%20Ayoub">Arshia Ayoub</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahid%20Ashraf%20Wani"> Zahid Ashraf Wani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the introduction of online social Q&A sites, people are able to reach each other efficiently for information seeking and simultaneously creating social bonds.

This element can be used for the analysis of thin shell structures, no matter how the geometrical shape might be. Tests on standard problems have been examined. The convergence of the new formulated element is also compared to other types of quadrilateral shell elements.

Santos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ever-escalating CO₂ concentration in the atmosphere calls for accelerated development and deployment of carbon capture processes to reduce emissions. Mixed matrix membranes (MMMs), which are fabricated by incorporating the beneﬁcial properties of highly selective inorganic ﬁllers into a polymer matrix, have exhibited signiﬁcant progress and the ability to enhance the performance of a membrane for gas separation. In this research, an amine-based ionic liquid (IL) [APTMS][AC] was prepared, which has greater CO₂ afﬁnity and greater solubility due to its amine moiety. The metal–organic framework (MOF) UiO-66 with a multidimensional crystalline structure was used as a ﬁller due to its appropriate porosity and tunable properties, and it was functionalized with NH₂. MOFs were further modiﬁed with an IL to prepare UiO-66@IL and UiO-66-NH₂@IL, and MMMs incorporating each MOF were fabricated with the polymer Pebax-1657. All the prepared membranes and MOFs were characterized to predict their separation efﬁciency. Several characterization techniques, namely, FTIR spectroscopy, XRD, and SEM, were used to successfully synthesize UiO-66@IL and UiO-66-NH₂@IL composites and conﬁrmed proper dispersion and excellent polymer‒ ﬁller compatibility at ﬁller loadings ranging from 0 to 30 wt.%. The separation performances were investigated, and the results showed that the incorporation of RTIL with the highly crystalline structure and large surface area of UiO-66 enhanced the separation efﬁciency of the membrane. The permeability of CO₂ for all fabricated membranes continuously increased with increasing ﬁller concentration, wherein the permeability was comparatively high for the UiO-66-NH₂ MMMs. The CO₂/CH₄ selectivity improved by 35%, 54%, and 60%, respectively, for UiO-66@IL, UiO-66-NH₂, and UiO-66-NH₂@IL MMMs compared to simple UiO-66 for CO₂/CH₄ and by 28%, 36%, and 63%, respectively, for CO₂/N₂, with an increase in ﬁller loading in the MMMs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gas%20separation" title="gas separation">gas separation</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20matrix%20membranes" title=" mixed matrix membranes"> mixed matrix membranes</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20sequestration" title=" CO₂ sequestration"> CO₂ sequestration</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20warming" title=" global warming"> global warming</a> </p> <a href="https://publications.waset.org/abstracts/193330/development-of-mixed-matrix-membranes-by-using-nh2-functionalized-uio-66-and-aptmsac-ionic-liquid-for-the-separation-of-co2" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193330.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">13</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">132</span> Exponential Spline Solution for Singularly Perturbed Boundary Value Problems with an Uncertain-But-Bounded Parameter </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Waheed%20Zahra">Waheed Zahra</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20El-Beltagy"> Mohamed El-Beltagy</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20El%20Mhlawy"> Ashraf El Mhlawy</a>, <a href="https://publications.waset.org/abstracts/search?q=Reda%20Elkhadrawy"> Reda Elkhadrawy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we consider singular perturbation reaction-diffusion boundary value problems, which contain a small uncertain perturbation parameter.

The study employs traditional as well as the modern approach of tracing out the efficiency and integration in the return series. From the results of efficiency it was observed that the market lacked efficiency in terms of its past information. The results of integration test clearly indicates that there was a long memory in the returns of GCC Shariah during the study period.

Management and prevention of alarmingly increasing disorders have attracted researchers to explore natural barriers against these disorders. The objective of this study was to explore oats as a potential source of dietary fiber. Extraction of dietary was optimized by response surface methodology, and five indigenous oat cultivars, including SGD2011, Avon, SGD81, PD2LV65, and S2000, were also characterized for techno-functional characteristics, mineral composition and phytochemical quantification. These cultivars varied significantly (p < 0.05) for oil holding capacity, water saturation, and water holding capacity, respectively. SGD81 showed the highest oil-holding capacity, water-holding capacity, and water saturation due to the highest fraction of dietary fiber. The highest values of total phenolic contents, total flavonoid contents, total flavonol contents, 2, 2-Diphenyl-1-picrylhydrazyl radical scavenging activity, and anthocyanin were shown by SGD81, and SGD2011, respectively. All cultivars varied significantly (P<0.05) with respect to phytochemical quantification. Oat cultivars SGD81 and SGD2011 showed the best phenolic acid profile and can be effectively used as a source of nutraceuticals. Beyond the nutritional properties of oats, these also contribute and emerged as potential sources of dietary fiber and have gained attention as nutraceutical cereal crops. This approach offers oats as a natural means of dietary fiber to protect humans from alarmingly increasing metabolic disorders, and its extraction by sonication has made it a sustainable and eco-friendly strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oat%20cultivars" title="oat cultivars">oat cultivars</a>, <a href="https://publications.waset.org/abstracts/search?q=dietary%20fibers" title=" dietary fibers"> dietary fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20profile" title=" mineral profile"> mineral profile</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=color%20properties" title=" color properties"> color properties</a> </p> <a href="https://publications.waset.org/abstracts/187064/techno-functional-characteristics-mineral-composition-and-antioxidant-potential-of-dietary-fiber-extracted-by-sonication-from-different-oat-cultivars-avena-sativa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187064.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">43</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">128</span> Urban Land Cover from GF-2 Satellite Images Using Object Based and Neural Network Classifications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lamyaa%20Gamal%20El-Deen%20Taha">Lamyaa Gamal El-Deen Taha</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20Sharawi"> Ashraf Sharawi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> China launched satellite GF-2 in 2014.

Pressure-time histories were obtained by data acquisition system from pressure sensors, installed on different points of room as well as veranda columns. The resulting damage pattern of different locations was observed during each test. Weak zones of masonry room were identified. Scaled distances for different damage levels in masonry room were experimentally obtained. The results provided a basis for determining the response of masonry room building against blast loading in a specific threat scenario. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=peak%20pressure" title="peak pressure">peak pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=composition-B" title=" composition-B"> composition-B</a>, <a href="https://publications.waset.org/abstracts/search?q=TNT" title=" TNT"> TNT</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20sensor" title=" pressure sensor"> pressure sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=scaled%20distance" title=" scaled distance"> scaled distance</a>, <a href="https://publications.waset.org/abstracts/search?q=masonry" title=" masonry"> masonry</a> </p> <a href="https://publications.waset.org/abstracts/157393/response-of-full-scale-room-building-against-blast-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157393.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">126</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">124</span> Male Oreochromis mossambica as Indicator for Water Pollution with Trace Elements in Relation to Condition Factor from Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Naeem">Muhammad Naeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20M.%20Moeen-ud-Din%20Raheel"> Syed M.

The immobilization of 2,6-dichlorophenolindophenol with MWCNTs was performed with a new synthetic strategy and characterized by UV–visible absorption spectroscopy, Fourier transform infrared spectroscopy and cyclic voltammetry. The cyclic voltammetric response of DPIP grafted onto MWCNTs indicated that it promotes the low potential, sensitive and stable determination of sulfide. The dependence of response currents on the concentration of sulfide was examined and was linear in the range of 10 - 1100 µM. The detection limit of sulfide was 5 µM and RSD for 100 and 500 µM sulfides were 1.8 and 1.3 %. Many interfering species had little or no effect on the determination of sulfide. The procedure was applied to determination of sulfide in waters samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=functionalized%20carbon%20nanotubes" title="functionalized carbon nanotubes">functionalized carbon nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfide" title=" sulfide"> sulfide</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20samples" title=" biological samples"> biological samples</a>, <a href="https://publications.waset.org/abstracts/search?q=2" title=" 2"> 2</a>, <a href="https://publications.waset.org/abstracts/search?q=6-dichlorophenolindophenol" title="6-dichlorophenolindophenol">6-dichlorophenolindophenol</a> </p> <a href="https://publications.waset.org/abstracts/48303/a-synthetic-strategy-to-attach-26-dichlorophenolindophenol-onto-multi-walled-carbon-nanotubes-and-their-application-for-electrocatalytic-determination-of-sulfide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48303.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">122</span> Development of a Numerical Model to Predict Wear in Grouted Connections for Offshore Wind Turbine Generators</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paul%20Dallyn">Paul Dallyn</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20El-Hamalawi"> Ashraf El-Hamalawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alessandro%20Palmeri"> Alessandro Palmeri</a>, <a href="https://publications.waset.org/abstracts/search?q=Bob%20Knight"> Bob Knight</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to better understand the long term implications of the grout wear failure mode in large-diameter plain-sided grouted connections, a numerical model has been developed and calibrated that can take advantage of existing operational plant data to predict the wear accumulation for the actual load conditions experienced over a given period, thus limiting the need for expensive monitoring systems. This model has been derived and calibrated based on site structural condition monitoring (SCM) data and supervisory control and data acquisition systems (SCADA) data for two operational wind turbine generator substructures afflicted with this challenge, along with experimentally derived wear rates. <p class="card-text"><strong>Keywords:</strong> <a
