Drying of pharmaceuticals by using microwave radiation is very limited, and the available information about the interaction between the electromagnetic radiations and the pharmaceutical material is still scarce. Therefore, microwave drying process is employed in this work to dry the wet (moisturised) granules of the formulated naproxen-sodium drug. This study aims to investigate the influences of the microwave radiation temperatures on the moisture removal, the crystalline structure, the size and morphology of the dried naproxen-sodium particles, and identify any potential changes in the chemical groups of the drug. In this work, newly formulated naproxen-sodium is prepared and moisturized by wet granulation process and hence dried by using microwave radiation at different temperatures. Moisture analyzer, Fourier-transform infrared spectroscopy, powder X-ray diffraction, and scanning electron microscope are used to characterise the non-moisturised powder (reference powder), the moisturised granules, and the dried particles. The results show that microwave drying of naproxen-sodium at high drying temperature is more efficient than that at low temperatures in terms of the moisture removal. Although there is no significant change in the chemical structure of the dried particles, the particle size, crystallinity and morphology are relatively changed with changing of heating temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heating%20temperature" title="heating temperature">heating temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20drying" title=" microwave drying"> microwave drying</a>, <a href="https://publications.waset.org/abstracts/search?q=naproxen-sodium" title=" naproxen-sodium"> naproxen-sodium</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20size" title=" particle size"> particle size</a> </p> <a href="https://publications.waset.org/abstracts/84916/impact-of-microwave-heating-temperatures-on-the-pharmaceutical-powder-characteristics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84916.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">161</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">51</span> Consequential Investigations on the Impact of Zakat Towards the Promotion of Socio-Economic Development in Morocco: A Theoretical Framework</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mennani%20Maha">Mennani Maha</a>, <a href="https://publications.waset.org/abstracts/search?q=Attak%20El%20Houssain"> Attak El Houssain</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Under the massive effect of the Covid-19 health crisis, marked by a loss of competitiveness, a slowdown in growth and an accumulation of the repercussions of socio-economic inequalities, a considerable effort must be combined, in Morocco, to put into perspective macro-political, macro-economic and social opportunities. The development of a new economic and social approach is essential in order to respond to the authenticity of the new development model that will be used by the country. The appropriation of strategies of solidarity and social cohesion constitutes a participatory, competitive and inclusive approach to support the functionalities of the economic, social and political system. Therefore, the search for alternative financial resources has become a necessity to achieve the objectives of sustainable socio-economic growth on the one hand; and to promote, on the other hands, the dynamics, of large scale, social investments. The zakat remains a site of the Islamic economy dedicated to stimulating the bases of a collective adhesion of the population on the economic, as well as on the social level, thanks to a fair and equitable distribution of the zakat funds. However, Morocco is one of the few Muslim countries that has not yet had an institution for collecting and distributing this Islamic duty, which makes it difficult to measure the socio-economic impact of zakat. This theoretical document essentially ensures the development of the crucial utility of institutionalizing zakat in order to reinforce the objectives of social solidarity in Morocco in line with the process of conceptualizing a new development model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=zakat" title="zakat">zakat</a>, <a href="https://publications.waset.org/abstracts/search?q=socio-economic%20development" title=" socio-economic development"> socio-economic development</a>, <a href="https://publications.waset.org/abstracts/search?q=solidarity" title=" solidarity"> solidarity</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20investment" title=" social investment"> social investment</a> </p> <a href="https://publications.waset.org/abstracts/144104/consequential-investigations-on-the-impact-of-zakat-towards-the-promotion-of-socio-economic-development-in-morocco-a-theoretical-framework" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144104.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">140</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">50</span> Pregnancy Rhinitis Prevalence among Saudi Women</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20G.%20Alotaibi">Mohammed G.

Therefore, our study was designed to evaluate the prevalence, triggering factors, severity and progression of rhinitis during pregnancy. Methods: Prospective cross-sectional study was conducted in eight governmental and private medical centers in Riyadh, Saudi Arabia, during June and July 2014. Validated Arabic language self-administered questionnaire was used. Sample size of 260 Saudi pregnant women was calculated by Raosoft sample size calculator. Random sampling was achieved by choosing one and skipping every five patients in the clinic list. Data were coded and entered manually into spreadsheets then transferred to SPSS statistical package version 16.0 for Windows. Consent, Privacy and confidentiality of information were assured. Results: Pregnancy rhinitis was reported 31.2% (CI 25.6 - 37.2%). Symptoms arising in first trimester appeared in 79.2% of PR cases and mostly worsen. The most prevalent symptoms were nasal pruritis (67.5%), followed by sneezing (57.1%), congestion (50.6%), and post nasal drip (46.7%). The major triggering factor was dust (71.4%), followed by Tobacco/Shisha smoke (57.6%) and perfume(47%). Preexisting allergic diseases were markedly associated with developing pregnancy rhinitis. Conclusion: Rhinitis during pregnancy manifested in one third of Saudi pregnant ladies. Nasal pruritus was the most common symptom and dust was the widespread triggering factor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=allergy" title="allergy">allergy</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnancy" title=" pregnancy"> pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=Rhinitis" title=" Rhinitis"> Rhinitis</a>, <a href="https://publications.waset.org/abstracts/search?q=sneezing" title=" sneezing"> sneezing</a> </p> <a href="https://publications.waset.org/abstracts/56954/pregnancy-rhinitis-prevalence-among-saudi-women" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56954.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">49</span> Relationship of Trace Minerals Nutritional Status of Camel (Camelus dromedarius) to Their Contents in Egyptian Feedstuff </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20Mohamed%20Hady%20Ali">Maha Mohamed Hady Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20A.%20El-Sayed"> M.

Camel, like other animal must receive all essential nutrients despite the hostile environment. A study was conducted to evaluate the nutritional status of some micro-minerals of camel under Egyptian environmental condition. Forty five blood samples were collected from apparently healthy male camels with an average age between 2-6 years at the slaughter house in Cairo province, Egypt. The animals were fed mainly on berseem (Trifolium alexandrinum) or concentrate with straw before slaughtering. The collected serum and feedstuff samples were subjected to copper, iron, selenium and zinc analysis using Atomic absorption spectrophotometer. The data showed variation in the level of copper, iron, selenium and zinc in the serum of the dromedary camel as well as in the feedstuffs. Furthermore, the results indicated that the micro- minerals status of feeds may not always reflected as such in camel blood suggesting some role of bioavailability. The main reason for the lack of such reflection seems to be the wide diversity exists in the surrounding environment (forages and plants) as well as the bioavailability of such minerals. Since the requirement of micro-minerals have not been established for camel, more researches must be focused on this topic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=camel" title="camel">camel</a>, <a href="https://publications.waset.org/abstracts/search?q=copper" title=" copper"> copper</a>, <a href="https://publications.waset.org/abstracts/search?q=egypt" title=" egypt"> egypt</a>, <a href="https://publications.waset.org/abstracts/search?q=feed%20stuff" title=" feed stuff"> feed stuff</a>, <a href="https://publications.waset.org/abstracts/search?q=iron" title=" iron"> iron</a>, <a href="https://publications.waset.org/abstracts/search?q=selenium" title=" selenium"> selenium</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc" title=" zinc"> zinc</a> </p> <a href="https://publications.waset.org/abstracts/31289/relationship-of-trace-minerals-nutritional-status-of-camel-camelus-dromedarius-to-their-contents-in-egyptian-feedstuff" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31289.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">522</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">48</span> Multimodal Deep Learning for Human Activity Recognition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ons%20Slimene">Ons Slimene</a>, <a href="https://publications.waset.org/abstracts/search?q=Aroua%20Taamallah"> Aroua Taamallah</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20Khemaja"> Maha Khemaja</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, human activity recognition (HAR) has been a key area of research due to its diverse applications. It has garnered increasing attention in the field of computer vision. HAR plays an important role in people’s daily lives as it has the ability to learn advanced knowledge about human activities from data. In HAR, activities are usually represented by exploiting different types of sensors, such as embedded sensors or visual sensors. However, these sensors have limitations, such as local obstacles, image-related obstacles, sensor unreliability, and consumer concerns. Recently, several deep learning-based approaches have been proposed for HAR and these approaches are classified into two categories based on the type of data used: vision-based approaches and sensor-based approaches. This research paper highlights the importance of multimodal data fusion from skeleton data obtained from videos and data generated by embedded sensors using deep neural networks for achieving HAR. We propose a deep multimodal fusion network based on a twostream architecture. These two streams use the Convolutional Neural Network combined with the Bidirectional LSTM (CNN BILSTM) to process skeleton data and data generated by embedded sensors and the fusion at the feature level is considered. The proposed model was evaluated on a public OPPORTUNITY++ dataset and produced a accuracy of 96.77%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20activity%20recognition" title="human activity recognition">human activity recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=action%20recognition" title=" action recognition"> action recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=sensors" title=" sensors"> sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=vision" title=" vision"> vision</a>, <a href="https://publications.waset.org/abstracts/search?q=human-centric%20sensing" title=" human-centric sensing"> human-centric sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=context-awareness" title=" context-awareness"> context-awareness</a> </p> <a href="https://publications.waset.org/abstracts/162633/multimodal-deep-learning-for-human-activity-recognition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162633.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">101</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">47</span> Child Maltreatment Prevention Readiness Assessment in the Kingdom of Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Majid%20Al-Eissa">Majid Al-Eissa</a>, <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Saleheen"> Hassan Saleheen</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatimah%20Al%20Shehri"> Fatimah Al Shehri</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20AlMuneef"> Maha AlMuneef </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Global efforts are being made to combat child maltreatment (CM); however, in 2011 the Kingdom of Saudi Arabia’s (KSA) response to this issue was found to be mediocre. Several developments have been implemented in KSA since then, and reevaluation is now necessary. The aim of this study is to assess the CM-prevention readiness (CMPR) of KSA in regard to implementing large-scale, evidence-based CM-prevention programs. Participants were decision makers and senior managers in the field of CM. Face-to-face interviews were conducted in the participants’ offices. This was a cross-sectional study. We used the multi-dimensional tool “Readiness Assessment for the Prevention of Child Maltreatment - short version,” which examines ten dimensions concerning this topic. Comparison between the results of this study and those of the 2011 examination was performed to determine how the situation in KSA has changed. Sixty informants were interviewed; the majority being females (57%) and from governmental institutions (56%). The average total score for the ten dimensions was 47.4%, an increase from the 43.7% reported in 2011. The strongest dimensions were legislations and mandates (8.3/10), followed by knowledge (7.1/10) and institutional links and resources (5.8/10). The lowest scores concerned human and technical resources (1.7/10) and attitude towards CM (2.8/10). Compared to the 2011 results, some dimensions showed significant improvements, but the majority had remained consistent. Time and commitment are necessary to secure CMPR improvement. Periodic assessment of CMPR is required to provide proper recommendations to the government regarding the progress of CM-prevention strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assessment" title="assessment">assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=child%20maltreatment" title=" child maltreatment"> child maltreatment</a>, <a href="https://publications.waset.org/abstracts/search?q=prevention" title=" prevention"> prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=readiness" title=" readiness"> readiness</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20Arabia" title=" Saudi Arabia "> Saudi Arabia </a> </p> <a href="https://publications.waset.org/abstracts/107143/child-maltreatment-prevention-readiness-assessment-in-the-kingdom-of-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107143.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">178</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">46</span> Amelioration of Over-Expression of bax, Nrf2 and NFК–β in Nano-Sized Titanium Dioxide-Intoxicated Mice by Potent Antioxidants </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20Z.%20Rizk">Maha Z.

The objective of this study is investigating either the effect of individual or combined doses of idebenone, carnosine and vitamin E on amelioration of some biochemical indices of nano sized titanium dioxide (TiO2 NPS) induced metabolic disorders in mice liver. TiO2-NPS was administered in an oral dose of 150 mg/kg for consecutive 14 days followed by oral daily doses of the aforementioned antioxidants for 1 month. TiO2-NPS induced a significant elevation in serum level of ALT and AST, hepatic inflammatory markers (tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6)) and increased the percent of DNA damage which was assessed by COMET assay in addition to the apoptotic marker Caspase-3. Moreover, mRNA gene expression observed by RT-PCR showed a significant overexpression in nuclear factor relation-2 (Nrf2), nuclear factor kappa beta (NF-Kβ) and the apoptotic factor (bax), and a significant down-regulation in the antiapoptotic factor (bcl2) level. In conclusion, idebenone, carnosine and vitamin E ameliorated the deviated parameters with a variable degree with the most pronounced role in alleviating the hazardous effect of TiO2 NPS toxicity following the combination regimen. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=idebenone" title="idebenone">idebenone</a>, <a href="https://publications.waset.org/abstracts/search?q=carnosine" title=" carnosine"> carnosine</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20E" title=" vitamin E"> vitamin E</a>, <a href="https://publications.waset.org/abstracts/search?q=TiO2%20NPS" title=" TiO2 NPS"> TiO2 NPS</a>, <a href="https://publications.waset.org/abstracts/search?q=caspase-3" title=" caspase-3"> caspase-3</a>, <a href="https://publications.waset.org/abstracts/search?q=NrF2" title=" NrF2"> NrF2</a>, <a href="https://publications.waset.org/abstracts/search?q=NF-KB" title=" NF-KB"> NF-KB</a> </p> <a href="https://publications.waset.org/abstracts/7223/amelioration-of-over-expression-of-bax-nrf2-and-nfk-v-in-nano-sized-titanium-dioxide-intoxicated-mice-by-potent-antioxidants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7223.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">386</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">45</span> Visual Speech Perception of Arabic Emphatics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20Saliba%20Foster">Maha Saliba Foster</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Speech perception has been recognized as a bi-sensory process involving the auditory and visual channels. Compared to the auditory modality, the contribution of the visual signal to speech perception is not very well understood. Studying how the visual modality affects speech recognition can have pedagogical implications in second language learning, as well as clinical application in speech therapy. The current investigation explores the potential effect of speech visual cues on the perception of Arabic emphatics (AEs). The corpus consists of 36 minimal pairs each containing two contrasting consonants, an AE versus a non-emphatic (NE). Movies of four Lebanese speakers were edited to allow perceivers to have partial view of facial regions: lips only, lips-cheeks, lips-chin, lips-cheeks-chin, lips-cheeks-chin-neck. In the absence of any auditory information and relying solely on visual speech, perceivers were above chance at correctly identifying AEs or NEs across vowel contexts; moreover, the models were able to predict the probability of perceivers’ accuracy in identifying some of the COIs produced by certain speakers; additionally, results showed an overlap between the measurements selected by the computer and those selected by human perceivers. The lack of significant face effect on the perception of AEs seems to point to the lips, present in all of the videos, as the most important and often sufficient facial feature for emphasis recognition. Future investigations will aim at refining the analyses of visual cues used by perceivers by using Principal Component Analysis and including time evolution of facial feature measurements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arabic%20emphatics" title="Arabic emphatics">Arabic emphatics</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=speech%20perception" title=" speech perception"> speech perception</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20speech%20perception" title=" visual speech perception"> visual speech perception</a> </p> <a href="https://publications.waset.org/abstracts/73033/visual-speech-perception-of-arabic-emphatics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73033.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">306</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">44</span> The Effect of Varying Cone Beam Computed Tomography Image Resolution and Field-of-View Centralization on the Effective Radiation Dose</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatima%20M.%20Jadu">Fatima M.

The aim of this study was to examine the effect of varying two CBCT technical factors, the voxel size (VOX) and the Field-of-View (FOV) centralization, on the radiation dose. Methodology: The head and neck slices of a RANDO® man phantom (Alderson Research Laboratories) were used with nanoDot™ OSLD dosimeters to measure the absorbed radiation dose at 25 predetermined sites. Imaging was done using the i-CAT® (Imaging Science International, Hatfield, PA, USA) CBCT unit. The VOX was changed for every three cycles of exposures from 0.2mm to 0.3mm and then 0.4mm. Then the FOV was centered on the maxilla and mandible alternatively while holding all other factors constant. Finally, the effective radiation dose was calculated for each view and voxel setting. Results: The effective radiation dose was greatest when the smallest VOX was chosen. When the FOV was centered on the maxilla, the highest radiation doses were recorded in the eyes and parotid glands. While on the mandible, the highest radiation doses were recorded in the sublingual and submandibular glands. Conclusion: Minor variations in the CBCT exposure factors significantly affect the effective radiation dose and thus the radiation risk to the patient. Therefore, extreme care must be taken when choosing these parameters especially for vulnerable patients such as children. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CBCT" title="CBCT">CBCT</a>, <a href="https://publications.waset.org/abstracts/search?q=cone%20beam%20CT" title=" cone beam CT"> cone beam CT</a>, <a href="https://publications.waset.org/abstracts/search?q=effective%20dose" title=" effective dose"> effective dose</a>, <a href="https://publications.waset.org/abstracts/search?q=field%20of%20view" title=" field of view"> field of view</a>, <a href="https://publications.waset.org/abstracts/search?q=mandible" title=" mandible"> mandible</a>, <a href="https://publications.waset.org/abstracts/search?q=maxilla" title=" maxilla"> maxilla</a>, <a href="https://publications.waset.org/abstracts/search?q=resolution" title=" resolution"> resolution</a>, <a href="https://publications.waset.org/abstracts/search?q=voxel" title=" voxel"> voxel</a> </p> <a href="https://publications.waset.org/abstracts/78167/the-effect-of-varying-cone-beam-computed-tomography-image-resolution-and-field-of-view-centralization-on-the-effective-radiation-dose" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78167.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">263</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">43</span> A Questionnaire Survey Reviewing Radiographers' Knowledge of Computed Tomography Exposure Parameters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Rawashdeh">Mohammad Rawashdeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20McEntee"> Mark McEntee</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20Zaitoun"> Maha Zaitoun</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Abdelrahman"> Mostafa Abdelrahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Brennan"> Patrick Brennan</a>, <a href="https://publications.waset.org/abstracts/search?q=Haytham%20Alewaidat"> Haytham Alewaidat</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Lewis"> Sarah Lewis</a>, <a href="https://publications.waset.org/abstracts/search?q=Charbel%20Saade"> Charbel Saade</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Despite the tremendous advancements that have been generated by Computed Tomography (CT) in the field of diagnosis, concerns have been raised about the potential cancer induction risk from CT because of the exponentially increased use of it in medicine. This study aims at investigating the application and knowledge of practicing radiographers in Jordan about CT radiation. In order to collect the primary data of this study, a questionnaire was designed and distributed by social media using a snow-balling sampling method. The respondents (n=54) have answered 36 questions including the questions about their demographic information, knowledge about Diagnostic Reference Levels (DRLs), CT exposure and adaptation of pediatric patients exposure. The educational level of the respondents was either at a diploma degree (35.2%) or bachelor (64.8%). The results of this study have indicated a good level of general knowledge between radiographers about the relationship between image quality, exposure parameters, and patient dose. The level of knowledge related to DRL was poor where less than 7.4 percent of the sample members were able to give specific values for a number of common anatomical fields, including abdomen, brain, and chest. Overall, Jordanian radiographers need to gain more knowledge about the expected levels of the dose when applying good practice. Additional education on DRL or DRL inclusion in educational programs is highlighted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computed%20tomography" title="computed tomography">computed tomography</a>, <a href="https://publications.waset.org/abstracts/search?q=CT%20scan" title=" CT scan"> CT scan</a>, <a href="https://publications.waset.org/abstracts/search?q=DRLs" title=" DRLs"> DRLs</a>, <a href="https://publications.waset.org/abstracts/search?q=exposure%20parameters" title=" exposure parameters"> exposure parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20quality" title=" image quality"> image quality</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation%20dose" title=" radiation dose"> radiation dose</a> </p> <a href="https://publications.waset.org/abstracts/107826/a-questionnaire-survey-reviewing-radiographers-knowledge-of-computed-tomography-exposure-parameters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107826.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">143</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">42</span> Effects of the Food Colour Erythrosine on Thyroid Gland Function in Experimental Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20M.Saber">Maha M.Saber</a>, <a href="https://publications.waset.org/abstracts/search?q=Eitedal%20Daoud"> Eitedal Daoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Moetazza%20M.%20Alshafei"> Moetazza M.

It had 17 chapters, and each is coded by an alphanumeric code: the letter corresponds to the chapter, the number to a paragraph in the chapter. The objective of this study is to show the utility of this classification in the coding of the reasons for demand for care in Primary health care (PHC), its advantages and limits. Methods: This is a cross-sectional descriptive study conducted in 4 PHC in Ariana district. Data on the demand for care during 2 days in the same week were collected. The coding of the information was done according to the CISP. The data was entered and analyzed by the EPI Info 7 software. Results: A total of 523 demands for care were investigated. The patients who came for the consultation are predominantly female (62.72%). Most of the consultants are young with an average age of 35 ± 26 years. In the ICPC, there are 7 rubrics: 'infections' is the most common reason with 49.9%, 'other diagnoses' with 40.2%, 'symptoms and complaints' with 5.5%, 'trauma' with 2.1%, 'procedures' with 2.1% and 'neoplasm' with 0.3%. The main advantage of the ICPC is the fact of being a standardized tool. It is very suitable for classification of the reasons for demand for care in PHC according to their specificity, capacity to be used in a computerized medical file of the PHC. Its current limitations are related to the difficulty of classification of some reasons for demand for care. Conclusion: The ICPC has been developed to provide healthcare with a coding reference that takes into account their specificity. The CIM is in its 10th revision; it would gain from revision to revision to be more efficient to be generalized and used by the teams of PHC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=international%20classification%20of%20primary%20care" title="international classification of primary care">international classification of primary care</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20file" title=" medical file"> medical file</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20health%20care" title=" primary health care"> primary health care</a>, <a href="https://publications.waset.org/abstracts/search?q=Tunisia" title=" Tunisia"> Tunisia</a> </p> <a href="https://publications.waset.org/abstracts/85569/international-classification-of-primary-care-as-a-reference-for-coding-the-demand-for-care-in-primary-health-care" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85569.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">266</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">40</span> TNF-α, TNF-β and IL-10 Gene Polymorphism and Association with Oral Lichen Planus Risk in Saudi Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20Ali%20Al-Mohaya">Maha Ali Al-Mohaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Lubna%20Majed%20Al-Otaibi"> Lubna Majed Al-Otaibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebtissam%20Nassir%20Al-Bakr"> Ebtissam Nassir Al-Bakr</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulrahman%20Al-Asmari"> Abdulrahman Al-Asmari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: Oral lichen planus (OLP) is a chronic inflammatory oral mucosal disease. Cytokines play an important role in the pathogenesis and disease progression of OLP. The purpose of this study was to investigate the association of tumor necrosis factor (TNF)-α, TNF-β and interleukin (IL)-10 gene polymorphisms with the OLP risk. Material and Methods: Forty-two unrelated patients with OLP and 211 healthy volunteers were genotyped for TNF-α (-308 G/A), TNF-β (+252A/G), IL-10 (-1082G/A), IL-10 (-819C/T), and IL-10 (-592C/A) polymorphisms. Results: The frequencies of allele A and genotype GA of TNF-α (-308G/A) were significantly higher while allele G and GG genotypes were lower in OLP patients as compared to the controls (P < 0.001). The frequency of GA genotype of TNF-β (+252A/G) was significantly higher in patients than in controls while the AA genotype was completely absent in OLP patients. These results indicated that allele A and genotype GA of TNF-α (-308G/A) as well as the GA genotype of TNF-β (+252A/G) polymorphisms are associated with OLP risk. The frequencies of alleles and genotypes of -1082G/A, -819C/T and -592C/A polymorphisms in IL-10 gene did not differ significantly between OLP patients and controls (P > 0.05). However, haplotype ATA extracted from 1082G/A, -819C/T, -592C/A polymorphisms of IL-10 were more prevalent in OLP patients when compared to controls indicating its possible association with OLP susceptibility. Conclusion: It is concluded that TNF-α (-308G/A), TNF-β (+252A/G) and IL-10 (-1082G/A, -819C/T and -592C/A) polymorphisms are associated with the susceptibility of OLP, thus giving additional support for the genetic basis of this disease. Further studies are required using a larger sample size to confirm this association and determine the prognostic values of these findings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oral%20lichen%20planus" title="oral lichen planus">oral lichen planus</a>, <a href="https://publications.waset.org/abstracts/search?q=cytokines" title=" cytokines"> cytokines</a>, <a href="https://publications.waset.org/abstracts/search?q=polymorphism" title=" polymorphism"> polymorphism</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic" title=" genetic"> genetic</a> </p> <a href="https://publications.waset.org/abstracts/45804/tnf-a-tnf-v-and-il-10-gene-polymorphism-and-association-with-oral-lichen-planus-risk-in-saudi-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45804.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">303</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> The Impact of Maternal Micronutrient Levels on Risk of Offspring Neural Tube Defects in Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eman%20M.%20El-Sayed">Eman M.

Poor nutrition was essential factor for central nervous system deformation. Mothers gave NTD offspring had abnormal serum levels of micronutrients. The present research was designed to study the effect of maternal micronutrient levels and oxidative stress on the incidence of NTD in offspring. The study included forty mothers; twenty of them of 30.9+7.28 years had conceived fetuses with NTD were considered as cases; and twenty mothers of 28.2 + 7.82 years with healthy neonates. We determined serum vitamin B12 and folic acid by using radioimmunoassays. Also, serum zinc was assessed using atomic absorption spectrophotometry. While serum copper and iron were measured colorimetrically and serum ceruloplasmin was analyzed by radialimmunodiffusion. Cases showed significantly lower levels of folic acid, vitamin B12 and zinc (P< 0.0005, 0.01, 0.01 respectively) than that of the control. Concentrations of copper, ceruloplasmin, and iron were markedly increased in cases as compared to controls (P < 0.01, 0.01, and 0.05 respectively). In conclusion, the current study clearly indicated the etiology of NTD cannot be explained with one strict etiologic mechanism, on the contrary, an interaction among maternal nutritional factors and oxidative stress would explain these anomalies. Vitamin B12, folic acid, and zinc supplementations should be considered for further decrease in the occurrence of NTD.

However, findings are not conclusive. We assume that inconsistent results of such association may be attributed to the regression models used in data analysis. To address this issue, we re-examine the effect of different dimension of accounting conservatism: unconditional conservatism (U_CONS) and conditional conservatism (C_CONS) on the COEC for a sample of listed firms from Middle Eastern and North Africa (MENA) countries, applying quantile regression (QR) approach developed by Koenker and Basset (1978). While classical ordinary least square (OLS) method is widely used in empirical accounting research, however it may produce inefficient and bias estimates in the case of departures from normality or long tail error distribution. QR method is more powerful than OLS to handle this kind of problem. It allows the coefficient on the independent variables to shift across the distribution of the dependent variable whereas OLS method only estimates the conditional mean effects of a response variable. We find as predicted that U_CONS has a significant positive effect on the COEC however, C_CONS has a negative impact. Findings suggest also that the effect of the two dimensions of accounting conservatism differs considerably across COEC quantiles. Comparing results from QR method with those of OLS, this study throws more lights on the association between accounting conservatism and COEC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unconditional%20conservatism" title="unconditional conservatism">unconditional conservatism</a>, <a href="https://publications.waset.org/abstracts/search?q=conditional%20conservatism" title=" conditional conservatism"> conditional conservatism</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20of%20equity%20capital" title=" cost of equity capital"> cost of equity capital</a>, <a href="https://publications.waset.org/abstracts/search?q=OLS" title=" OLS"> OLS</a>, <a href="https://publications.waset.org/abstracts/search?q=quantile%20regression" title=" quantile regression"> quantile regression</a>, <a href="https://publications.waset.org/abstracts/search?q=emerging%20markets" title=" emerging markets"> emerging markets</a>, <a href="https://publications.waset.org/abstracts/search?q=MENA%20countries" title=" MENA countries"> MENA countries</a> </p> <a href="https://publications.waset.org/abstracts/18733/the-effect-of-accounting-conservatism-on-cost-of-capital-a-quantile-regression-approach-for-mena-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18733.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">355</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">37</span> Factors Impacting Technology Integration in EFL Classrooms: A Study of Qatari Independent Schools</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Youmen%20Chaaban">Youmen Chaaban</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20Ellili-Cherif"> Maha Ellili-Cherif</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study was to examine the effects of teachers’ individual characteristics and perceptions of environmental factors that impact their technology integration into their EFL (English as a Foreign Language) classrooms. To this end, a national survey examining EFL teachers’ perceptions was conducted at Qatari Independent schools. 263 EFL teachers responded to the survey which investigated several factors known to impact technology integration. These factors included technology availability and support, EFL teachers’ perceptions of importance, obstacles facing technology integration, competency with technology use, and formal technology preparation. The impact of these factors on teachers’ and students’ educational technology use was further measured. The analysis of the data included descriptive statistics and a chi-square analysis test in order to examine the relationship between these factors. The results revealed important cultural factors that impact teachers’ practices and attitudes towards technology in the Qatari context. EFL teachers were found to integrate technology most prominently for instructional delivery and preparation. The use of technology as a learning tool received less emphasis. Teachers further revealed consistent perceptions about obstacles to integration, high levels of confidence in using technology, and consistent beliefs about the importance of using technology as a learning tool. Further analyses of the factors impacting technology integration can assist with Qatar’s technology advancement and development efforts by indicating the areas of strength and areas where additional efforts are needed. The results will lay the foundation for conducting context-specific professional development suitable for the needs of EFL teachers in Qatari Independent Schools. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=educational%20technology%20integration" title="educational technology integration">educational technology integration</a>, <a href="https://publications.waset.org/abstracts/search?q=Qatar" title=" Qatar"> Qatar</a>, <a href="https://publications.waset.org/abstracts/search?q=EFL" title=" EFL"> EFL</a>, <a href="https://publications.waset.org/abstracts/search?q=independent%20schools" title=" independent schools"> independent schools</a>, <a href="https://publications.waset.org/abstracts/search?q=ICT" title=" ICT "> ICT </a> </p> <a href="https://publications.waset.org/abstracts/42965/factors-impacting-technology-integration-in-efl-classrooms-a-study-of-qatari-independent-schools" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42965.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">383</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">36</span> The Impact of Unconditional and Conditional Conservatism on Cost of Equity Capital: A Quantile Regression Approach for MENA Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalifa%20Maha">Khalifa Maha</a>, <a href="https://publications.waset.org/abstracts/search?q=Ben%20Othman%20Hakim"> Ben Othman Hakim</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Hussainey"> Khaled Hussainey </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Prior empirical studies have investigated the economic consequences of accounting conservatism by examining its impact on the cost of equity capital (COEC).

This research paper examines the validity and effectiveness of mid-career professional journalistic training in the UAE. The research focuses on Arab journalists’ perceptions and attitudes towards professional training, and the state of journalistic training courses available to them, in comparison to modern trends of professional training. The two main objectives of this paper are to examine how different factors affect the effectiveness of the mid-career training offered to Arab Journalists in UAE, whether they are institutional factories, socio-economic factors, personal factors, etc. Then, to suggest a practical roadmap to improve the mid-career journalism training in the UAE. The research methodology combines qualitative and quantitative approaches. As researchers conduct in-depth interviews with a sample of Arab journalists in the UAE, Media outlets in UAE encompass private and governmental entities, with media products in Arabic and/or English, online and/or offline as well. Besides, content analysis will be applied to the available online and offline journalistic training courses offered to Arab journalists’ in UAE along the past three years. Research outcomes are expected to be helpful and practical to improve professional training in the UAE and to determine comprehensive and concrete criteria to provide up-to-date professional training, and to evaluate its validity. Results and research outcomes can help to better understand the current status of mid-career journalistic training in the UAE, to evaluate it based on studying both; the targeted trainees and the up-to-date journalistic training trends. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arab%20journalists" title="Arab journalists">Arab journalists</a>, <a href="https://publications.waset.org/abstracts/search?q=Arab%20journalism%20culture" title=" Arab journalism culture"> Arab journalism culture</a>, <a href="https://publications.waset.org/abstracts/search?q=journalism%20practice" title=" journalism practice"> journalism practice</a>, <a href="https://publications.waset.org/abstracts/search?q=journalism%20and%20technology" title=" journalism and technology"> journalism and technology</a> </p> <a href="https://publications.waset.org/abstracts/115602/factors-affecting-on-mid-career-training-for-arab-journalists-united-arab-emirates-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115602.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">34</span> An Evaluation of Neuropsychiatric Manifestations in Systemic Lupus Erythematosus Patients in Saudi Arabia and Their Associated Factors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yousef%20M.%20Alammari">Yousef M.

Methods: During June 2021, this cross-sectional study was carried out among SLE patients in Saudi Arabia. The Saudi Rheumatism Association exploited social media platforms to provide a self-administered online questionnaire to SLE patients. All data analyses were performed using the Statistical Packages for Social Sciences (SPSS) version 26. Results: Two hundred and five SLE patients participated in the study (females 91.3 % vs. males 8.7 %). In addition, 13.5 % of patients had a family history of SLE, and 26% had SLE for one to three years. Alteration or loss of sensation (53.4%), Fear (52.4%), and headache (48.1%) were the most prevalent signs of neuropsychiatric symptoms in systemic lupus erythematosus (NPSLE) patients. The prevalence of patients with NPSLE was 40%. In a multivariate regression model, fear, altered sensations, cerebrovascular illness, sleep disruption, and diminished interest in routine activities were identified as independent risk variables for NPSLE. Conclusion: Nearly half of SLE patients demonstrated NP manifestations, with significant symptoms including fear, alteration of sensation, cerebrovascular disease, sleep disturbance, and reduced interest in normal activities. To detect the pathophysiology of NPSLE, it is necessary to understand the relationship between neuropsychiatric morbidity and other relevant rheumatic disorders in the SLE population. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neuropsychiatric" title="neuropsychiatric">neuropsychiatric</a>, <a href="https://publications.waset.org/abstracts/search?q=systemic%20lupus%20erythematosus" title=" systemic lupus erythematosus"> systemic lupus erythematosus</a>, <a href="https://publications.waset.org/abstracts/search?q=NPSLE" title=" NPSLE"> NPSLE</a>, <a href="https://publications.waset.org/abstracts/search?q=prevalence" title=" prevalence"> prevalence</a>, <a href="https://publications.waset.org/abstracts/search?q=SLE%20patients" title=" SLE patients"> SLE patients</a> </p> <a href="https://publications.waset.org/abstracts/167614/an-evaluation-of-neuropsychiatric-manifestations-in-systemic-lupus-erythematosus-patients-in-saudi-arabia-and-their-associated-factors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167614.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">75</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">33</span> Effect of Palatal Lift Prosthesis on Speech Clarity in Flaccid Dysarthria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Firas%20Alfwaress">Firas Alfwaress</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelraheem%20Bebers%20Abdelhadi%20Hamasha"> Abdelraheem Bebers Abdelhadi Hamasha</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20Abu%20Awaad"> Maha Abu Awaad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: The aim of the present study was to investigate the effect of Palatal Lift Prosthesis (PLP) on speech clarity in patients with Flaccid Dysarthria. Five speech measures were investigated including Nasalance Scores, Diadchokinetic (DDK), Vowel Duration, airflow, and Sound Intensity. Participants: Twelve (7 Males and 5 females) native speakers of Jordanian Arabic with Flaccid Dysarthria following stroke, traumatic brain injury, and amyotrophic lateral sclerosis were included. The age of the participants ranged from 8–65 years with an average of 31.75 years. Design: Nasalance Scores, Diadchokinetic rate, Vowel Duration, and Sound Intensity were obtained using the Nasometer II, Model 6450 in three conditions. The first condition included obtaining the five measures without wearing the customized Palatal Lift Prosthesis. The second and third conditions included obtaining the five measures immediately after wearing the Palatal Lift Prosthesis and three months later. Results: Palatal lift prosthesis was found to be effective in individuals with flaccid dysarthria. Results showed decrease in the Nasalance Scores for the syllable repetition tasks and vowel prolongation tasks when comparing the means in the pre PLP with the post PLP at p≤0.001 except for the /m/ prolongation task. Results showed increased DDK repetition task, airflow amount, and sound intensity, and a decrease in vowel length at p≤0.001. Conclusions: The use of palatal lift prosthesis is effective in improving the speech of patients with flaccid dysarthria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=palatal%20lift%20prosthesis" title="palatal lift prosthesis">palatal lift prosthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=flaccid%20dysarthria" title=" flaccid dysarthria"> flaccid dysarthria</a>, <a href="https://publications.waset.org/abstracts/search?q=hypernasality" title=" hypernasality"> hypernasality</a>, <a href="https://publications.waset.org/abstracts/search?q=speech%20clarity" title=" speech clarity"> speech clarity</a>, <a href="https://publications.waset.org/abstracts/search?q=diadchokinetic%20rate" title=" diadchokinetic rate"> diadchokinetic rate</a> </p> <a href="https://publications.waset.org/abstracts/16323/effect-of-palatal-lift-prosthesis-on-speech-clarity-in-flaccid-dysarthria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16323.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">386</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">32</span> Exploring the Safety of Sodium Glucose Co-Transporter-2 Inhibitors at the Imperial College London Diabetes Centre, UAE</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raad%20Nari">Raad Nari</a>, <a href="https://publications.waset.org/abstracts/search?q=Maura%20Moriaty"> Maura Moriaty</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20T.%20Barakat"> Maha T.

They are used to improve glycaemic control in adults with type 2 diabetes by enhancing urinary glucose excretion. In the UAE, there has been certainly an increased use of these medications. As with any new medication, there are safety considerations related to their use in patients with type two diabetes. A retrospective study was conducted at the three main centres of the Imperial College London Diabetes Centre. Methodology: All patients in electronic database (Diamond) from October 2014 to October 2017 were included with a minimum of six months usage of sodium glucose co-transporter inhibitors that comprise canagliflozin, dapagliflozin and empagliflozin. There were 15 paired sample biochemical and clinical correlations. The analysis was done at the start of the study, three months and six months apart. SPSS version 24 was used for this study. Conclusion: This study of sodium glucose co-transporter-2 inhibitors used showed significant reductions in weight, glycated haemoglobin A1C, systolic and diastolic blood pressures. As the case with systematic reviews, there were similar changes in liver enzymes, raised total cholesterol, low density lipopoptein and high density lipoprotein. There was slight improvement in estimated glomerular filtration rate too. Our analysis also showed that they increased in the incidence of urinary tract symptoms and incidence of urinary tract infections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SGLT2%20inhibitors%20dapagliflozin%20empagliflozin%20canagliflozin" title="SGLT2 inhibitors dapagliflozin empagliflozin canagliflozin">SGLT2 inhibitors dapagliflozin empagliflozin canagliflozin</a>, <a href="https://publications.waset.org/abstracts/search?q=adverse%20effects" title=" adverse effects"> adverse effects</a>, <a href="https://publications.waset.org/abstracts/search?q=amputation%20diabetic%20ketoacidosis%20DKA" title=" amputation diabetic ketoacidosis DKA"> amputation diabetic ketoacidosis DKA</a>, <a href="https://publications.waset.org/abstracts/search?q=urinary%20tract%20infection" title=" urinary tract infection"> urinary tract infection</a> </p> <a href="https://publications.waset.org/abstracts/93819/exploring-the-safety-of-sodium-glucose-co-transporter-2-inhibitors-at-the-imperial-college-london-diabetes-centre-uae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93819.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">229</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 Impact of Child Maltreatment on School Performance in Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al%20Muneef%20Maha">Al Muneef Maha</a>, <a href="https://publications.waset.org/abstracts/search?q=Al%20Tamimi%20Dana"> Al Tamimi Dana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Child maltreatment was proven to negatively impact children’s and adolescent’s academic performances; showing less academic achievements, problems completing homework assignments, and was marginally associated with being frequently absent from school (1). Objectives: To identify the impact of child maltreatment on school performance among adolescents in National Guard Schools. Materials and Methods: The study was conducted at National Guard schools in Riyadh. Students aged 12-19 years were invited to participate. Participants (N=674) completed the survey instrument which included demographics, exposure to different types of abuse, and overall level of academic performance. Results: Participants’ mean age was 15.6±1.6 years and males (53%). Ninety-five percent lived with both parents, 2% with single parent, and 3% with step parents. Four percent lived with alcoholic parents or guardians, and 7% have lived with a family member who has been arrested or imprisoned. Poor performance (failure in exam) were more likely among the students who lived with alcoholics vs. non-alcoholics (33% vs. 11%, p<0.01), imprisoned family member vs. non-imprisoned (26% vs. 11%, p<0.01), psychologically abused vs. not abused (21% vs. 10%, p<0.01), physically abused vs. not abused (19% vs. 9%, p<0.01). Predisposing factors to poor performance in school included living with alcoholic parents or guardians (OR=2.8, CI=1.1-6.7), psychologically abused (OR=1.7, CI=1.0-3.0), and physically abused (OR=1.7, CI=1.0-2.8). Conclusions: The results suggest that child maltreatment may adversely impact school performance. These findings highlight the importance of increasing the awareness about the impact of child maltreatment on school performance among families, schools, and the community. Recommend to the Ministry of Education to consider counseling of students with poor performance due to adverse child experiences or maltreatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=child%20abuse" title="child abuse">child abuse</a>, <a href="https://publications.waset.org/abstracts/search?q=child%20maltreatment" title=" child maltreatment"> child maltreatment</a>, <a href="https://publications.waset.org/abstracts/search?q=school%20performance" title=" school performance"> school performance</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20Arabia" title=" Saudi Arabia"> Saudi Arabia</a> </p> <a href="https://publications.waset.org/abstracts/20857/the-impact-of-child-maltreatment-on-school-performance-in-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20857.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">326</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> Irregular Meal Pattern: What Is the Impact on Weight</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20Alhussain">Maha Alhussain</a>, <a href="https://publications.waset.org/abstracts/search?q=Moira%20A%20Taylor"> Moira A Taylor</a>, <a href="https://publications.waset.org/abstracts/search?q=Ian%20A.%20Macdonald"> Ian A.

The present study investigated the effect of irregular meal frequency on anthropometric measurements and energy expenditure (EE) in healthy women. Design: 11 healthy weight women (18–40 years) were studied in a randomized crossover trial with two phases of 2 weeks each. In Phase 1, participants consumed either a regular meal pattern (6 meals/day) or an irregular meal pattern (varying from 3 to 9 meals/day). In Phase 2, participants followed the alternative meal pattern to that followed in Phase 1, after a 2-weeks washout period. In the two phases, identical foods were provided to a participant in amounts designed to keep body weight constant. Participants came to the laboratory after an overnight fast at the start and end of each phase. EE was measured in fasting state by indirect calorimetry. Postprandial EE was measured during the 3 h period after consumption of a milkshake, test drink. Results: There were no significant changes in body weight and anthropometric measurements after both meal pattern interventions. There was also no significant difference in mean daily energy intake between the regular and irregular meal pattern (2043 ±31 and 2099 ±33 respectively). EE in the fasting state showed no significant differences cross the experiment visits. There was a significant difference in Postprandial EE (measured for 3 h) by visit (P=0.04). Postprandial EE after the regular meal pattern was significantly higher than at baseline (P=0.002) or than after the irregular meal pattern (P= 0.04). Conclusion: Eating regularly for 14-day period significantly increases Postprandial EE which may contribute to weight loss and obesity management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20expenditure" title="energy expenditure">energy expenditure</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20intake" title=" energy intake"> energy intake</a>, <a href="https://publications.waset.org/abstracts/search?q=meal%20pattern" title=" meal pattern"> meal pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=weight%20loss" title=" weight loss"> weight loss</a> </p> <a href="https://publications.waset.org/abstracts/27426/irregular-meal-pattern-what-is-the-impact-on-weight" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27426.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">413</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> Protective Impact of Some Natural Extracts Against Acute Hepatotoxicity in Wistar Rats: DNA Protecting, Antioxidant and Anti-Inflammatory Effects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yara%20Mohamed%20Taha">Yara Mohamed Taha</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Ali%20El%20Desouky"> Mohamed Ali El Desouky</a>, <a href="https://publications.waset.org/abstracts/search?q=Heba%20Kamal%20Abdel%20Hakim"> Heba Kamal Abdel Hakim</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20Hanafy%20Mahmoud"> Maha Hanafy Mahmoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hepatotoxicity due to drugs and toxic chemicals constitutes a crucial health problem nowadays. Medicinal plants are widely used recently for protecting against many liver disorders and inflammatory conditions. This study aims to evaluate hepatoprotective impact of green tea extract (GTE), rosemary extract (RE) and rosmarinic acid (RA) against hepatotoxins; ferric nitrilotriacetate (Fe-NTA) and diethylnitrosamine (DEN) in rats. Five groups of male Wistar rats were included; one control negative, while the other groups were treated intraperitoneally with DEN as 160 mg.kg-1 b.w. on 15th day and Fe-NTA as 5 mg.kg-1 b.w. on 33rd day. One of them was control positive. The other three groups were pre-administered with daily protective oral doses of either 200 mg.kg-1 b.w. of RE or 1 g.kg- 1 b.w. of GTE or 50 mg.kg-1 b.w. of RA two weeks prior to DEN exposure and continued till the end of the experimental period. The obtained data revealed a highly significant increase of MDA, 8-OHdG, DNA damage percent, a significant depletion of GSH and elevated Gr-1 protein expression in hepatocytes with liver tissue histopathological changes of rats exposed to DEN+Fe-NTA. Pre-administration of protective doses of RE, GTE and RA to DEN+Fe-NTA treated rats could normalize the altered biochemical, histopathological and immunohistochemical parameters. In conclusion, RE, GTE and RA showed a hepatoprotective effect against liver toxicity induced by DEN+Fe-NTA, with the best antioxidant and anti-inflammatory impact were for RA and GTE. Therefore, the current study declared that rosemary, green tea and products enriched with rosmarinic acid should be involved daily in diet of people who are exposed to chemicals and environmental toxins to protect themselves from hepatotoxicity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hepatotoxicity" title="hepatotoxicity">hepatotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=diethylnitrosamine%20and%20ferric%20nitrilotriacetate" title=" diethylnitrosamine and ferric nitrilotriacetate"> diethylnitrosamine and ferric nitrilotriacetate</a>, <a href="https://publications.waset.org/abstracts/search?q=rosemary%20extract%20%28RE%29" title=" rosemary extract (RE)"> rosemary extract (RE)</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20tea%20extract%20%28GTE%29" title=" green tea extract (GTE)"> green tea extract (GTE)</a>, <a href="https://publications.waset.org/abstracts/search?q=rosmarinic%20acid%20%28RA%29" title=" rosmarinic acid (RA)"> rosmarinic acid (RA)</a> </p> <a href="https://publications.waset.org/abstracts/170967/protective-impact-of-some-natural-extracts-against-acute-hepatotoxicity-in-wistar-rats-dna-protecting-antioxidant-and-anti-inflammatory-effects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170967.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">92</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">28</span> Cytotoxic, Antimicrobial and Antiviral Activities of Acovenoside A: A Cardenolide Isolated from an Egyptian Cultivar of Acokanthera spectabilis Leaves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Howaida%20I.%20Abd-Alla">Howaida I.

The infusion of their leaves is gargled to treat tonsillitis and is used medicinally to treat snakebites. The total cardiac glycosides content in the leaves was determined by referring to gitoxigenin as a reference compound. Two triterpenes, lup-20(29)-en-3β-ol (1) and oleanolic acid (2); two cardenolides, acovenoside A (3) and acobioside A (4) were isolated from the ethyl acetate extract. Their structures were determined on the basis of spectral analysis. Major constituents isolated from this species were evaluated for cytotoxicity against normal lung cell line (Wi38) and antimicrobial activities against Gram-positive (two strains) and Gram-negative bacteria (four strains), yeast-like fungi (two strains) and fungi (five strains). The minimum inhibitory concentration (MIC) of the compounds was determined using broth microdilution method. Their viral inhibitory effects against avian influenza virus type A (AI-H5N1) and Newcastle disease virus (NDV) in specific pathogen free (SPF) embryonated chicken eggs (ECE), chicken embryo fibroblasts (CEF) and Vero cells were evaluated. The cardenolide (3) showed viral inhibitory effects against AI-H5N1 and NDV in SPF ECE. The two cardenolides isolated have shown potent cytotoxicity against Vero cells. Compound (3) showed potent anti-Gram-negative bacteria activity. These results suggested that acovenoside A might be promising for future antiviral and antimicrobial drug design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Acokanthera" title="Acokanthera">Acokanthera</a>, <a href="https://publications.waset.org/abstracts/search?q=AI-H5N1" title=" AI-H5N1"> AI-H5N1</a>, <a href="https://publications.waset.org/abstracts/search?q=Cardenolides" title=" Cardenolides"> Cardenolides</a>, <a href="https://publications.waset.org/abstracts/search?q=NDV" title=" NDV"> NDV</a>, <a href="https://publications.waset.org/abstracts/search?q=SPF-ECE" title=" SPF-ECE"> SPF-ECE</a>, <a href="https://publications.waset.org/abstracts/search?q=VERO" title=" VERO"> VERO</a>, <a href="https://publications.waset.org/abstracts/search?q=Wi38" title=" Wi38 "> Wi38 </a>, <a href="https://publications.waset.org/abstracts/search?q=Microbe" title=" Microbe "> Microbe </a> </p> <a href="https://publications.waset.org/abstracts/93780/cytotoxic-antimicrobial-and-antiviral-activities-of-acovenoside-a-a-cardenolide-isolated-from-an-egyptian-cultivar-of-acokanthera-spectabilis-leaves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93780.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">178</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> Hot Deformability of Si-Steel Strips Containing Al</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Yousef">Mohamed Yousef</a>, <a href="https://publications.waset.org/abstracts/search?q=Magdy%20Samuel"> Magdy Samuel</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20El-Meligy"> Maha El-Meligy</a>, <a href="https://publications.waset.org/abstracts/search?q=Taher%20El-Bitar"> Taher El-Bitar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present work is dealing with 2% Si-steel alloy. The alloy contains 0.05% C as well as 0.85% Al. The alloy under investigation would be used for electrical transformation purposes. A heating (expansion) - cooling (contraction) dilation investigation was executed to detect the a, a+g, and g transformation temperatures at the inflection points of the dilation curve. On heating, primary a  was detected at a temperature range between room temperature and 687 <sup>o</sup>C. The domain of a+g was detected in the range between 687<sup> o</sup>C and 746<sup> o</sup>C. g phase exists in the closed g region at the range between 746<sup> o</sup>C and 1043 <sup>o</sup>C. The domain of a phase appears again at a temperature range between 1043 and 1105 <sup>o</sup>C, and followed by secondary a at temperature higher than 1105<sup> o</sup>C. A physical simulation of thermo-mechanical processing on the as-cast alloy was carried out. The simulation process took into consideration the hot flat rolling pilot plant parameters. The process was executed on the thermo-mechanical simulator (Gleeble 3500). The process was designed to include seven consecutive passes. The 1<sup>st</sup> pass represents the roughing stage, while the remaining six passes represent finish rolling stage. The whole process was executed at the temperature range from 1100<sup> o</sup>C to 900<sup> o</sup>C. The amount of strain starts with 23.5% at the roughing pass and decreases continuously to reach 7.5 % at the last finishing pass. The flow curve of the alloy can be abstracted from the stress-strain curves representing simulated passes. It shows alloy hardening from a pass to the other up to pass no. 6, as a result of decreasing the deformation temperature and increasing of cumulative strain. After pass no. 6, the deformation process enhances the dynamic recrystallization phenomena to appear, where the z-parameter would be high. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=si-%20steel" title="si- steel">si- steel</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20deformability" title=" hot deformability"> hot deformability</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20transformation%20temperature" title=" critical transformation temperature"> critical transformation temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20simulation" title=" physical simulation"> physical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=thermo-mechanical%20processing" title=" thermo-mechanical processing"> thermo-mechanical processing</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20curve" title=" flow curve"> flow curve</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20softening." title=" dynamic softening."> dynamic softening.</a> </p> <a href="https://publications.waset.org/abstracts/76819/hot-deformability-of-si-steel-strips-containing-al" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76819.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">245</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">26</span> Biomimetic Architecture: The Bio Process to an Eco-Friendly Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Odeyemi%20Ifeoluwayemi">Odeyemi Ifeoluwayemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20Joushua"> Maha Joushua</a>, <a href="https://publications.waset.org/abstracts/search?q=Fulani%20Omoyeni"> Fulani Omoyeni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the search for sustainability, over time, architectural approaches to design have moved from just nature inspired design to the study of nature’s principles to produce effective designs that solve the issue of sustainability. Nature has established materials, shapes and processes that are effective right from a minor scale to an enormous scale. A branch of human knowledge that studies nature is called biology. Biology helps us to grasp and understand nature. Biomimicry is a new way of viewing and valuing nature, based not on what we can extract from the natural world but on what we can learn from it. Life has sustained on the earth for the last 3.85 billion years, and it is necessary for us to find out how life has been able to stay sustained for that long. The building must teach the society new ecological morals, thus, a better understanding of how nature works can usefully inspire architectural designs to resolve issues that have already been resolved by nature. This will not only help in creating a healthy environment but will also produce positive environmental impacts. Biomimetic Architecture connects and reproduces the ideologies found in nature in order to create built environment which benefit people and other living creatures as well as preserving it for the future. Understanding the bioprocess would lead to the establishment of ecological approaches that serve as a platform for creating a built environment that goes beyond sustaining current settings but also mimic nature’s regenerative ecosystem. This paper aims to explain these design methods under the name of biomimicry and biomimetic architecture by reviewing literature and research works done by examining these approaches classified as forms, processes and ecosystems. It is expected that this research will provide information that would, therefore, lead to the creation of buildings that are eco-friendly and provide greater comfort to the populaces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomimetic%20architecture" title="biomimetic architecture">biomimetic architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=biomimicry" title=" biomimicry"> biomimicry</a>, <a href="https://publications.waset.org/abstracts/search?q=ecological%20design" title=" ecological design"> ecological design</a>, <a href="https://publications.waset.org/abstracts/search?q=nature" title=" nature"> nature</a> </p> <a href="https://publications.waset.org/abstracts/47176/biomimetic-architecture-the-bio-process-to-an-eco-friendly-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47176.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">256</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> Mixed Hydrotropic Zaleplon Oral Tablets: Formulation and Neuropharmacological Effect on Plasma GABA Level</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghada%20A.%20Abdelbary">Ghada A.

The aim of the present study is to enhance the solubility and consequently the bioavailability of ZP using hydrotropic agents (HA). Phase solubility diagrams of ZP in presence of different molar concentrations of HA (Sodium benzoate, Urea, Ascorbic acid, Resorcinol, Nicotinamide, and Piperazine) were constructed. ZP/Sodium benzoate and Resorcinol microparticles were prepared adopting melt, solvent evaporation and melt-evaporation techniques followed by XRD. Directly compressed mixed hydrotropic ZP tablets of Sodium benzoate and Resorcinol in different weight ratios were prepared and evaluated compared to the commercially available tablets (Sleep aid® 5 mg). The effect of shelf and accelerated stability storage (40°C ± 2°C/75%RH ± 5%RH) on the optimum tablet formula (F5) for six months were studied. The enhancement of ZP solubility follows the order of: Resorcinol > Sodium benzoate > Ascorbic acid > Piperazine > Urea > Nicotinamide with about 350 and 2000 fold increase using 1M of Sodium benzoate and Resorcinol respectively. ZP/HA microparticles exhibit the order of: Solvent evaporation > melt-solvent evaporation > melt > physical mixture which was further confirmed by the complete conversion of ZP into amorphous form. Mixed hydrotropic tablet formula (F5) composed of ZP/(Resorcinol: Sodium benzoate 4:1w/w) microparticles prepared by solvent evaporation exhibits in-vitro dissolution of 31.7±0.11% after five minutes (Q5min) compared to 10.0±0.10% for Sleep aid® (5 mg) respectively. F5 showed significantly higher GABA concentration of 122.5±5.5mg/mL in plasma compared to 118±1.00 and 27.8±1.5 mg/mL in case of Sleep aid® (5 mg) and control taking only saline respectively suggesting a higher neuropharmacological effect of ZP following hydrotropic solubilization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=zaleplon" title="zaleplon">zaleplon</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrotropic%20solubilization" title=" hydrotropic solubilization"> hydrotropic solubilization</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20GABA%20level" title=" plasma GABA level"> plasma GABA level</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20hydrotropy" title=" mixed hydrotropy"> mixed hydrotropy</a> </p> <a href="https://publications.waset.org/abstracts/30664/mixed-hydrotropic-zaleplon-oral-tablets-formulation-and-neuropharmacological-effect-on-plasma-gaba-level" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30664.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">445</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> Strategic Alliances and Creative Synergy within European Union: A Theoretical Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20Tichetti">Maha Tichetti</a>, <a href="https://publications.waset.org/abstracts/search?q=Barzi%20Redouane"> Barzi Redouane</a>, <a href="https://publications.waset.org/abstracts/search?q=Selim%20Kanat"> Selim Kanat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the European Union (EU), where economic, political, and cultural ties converge, strategic alliances play a pivotal role in shaping the collaborative landscape. This paper embarks on a journey into the EuroSphere, offering a comprehensive analysis review that unravels the dynamics of these alliances within the European context. The focus is specifically directed towards understanding their profound impact on creative synergy and innovation among teams. In our analysis, we provide theoretical explanations for key terms such as "creative synergy" and "strategic alliances." We outline various types of competitive strategies, delve into the motivations prompting the formation of strategic alliances, and critically examine the success and failure factors in these kinds of collaboration. Additionally, we explore the goals achievable through strategic alliances, especially in the context of external growth. A central focus of this paper focus on how strategic alliances can significantly impact creative synergy within the European landscape. Through a theoretical lens, we explore the interplay between collaborative strategies and the enhancement of creative thinking within teams engaged in strategic alliances. The article goes beyond theoretical frameworks to present a tangible example of a strategic alliance emerging in the European market. This case study illuminates how such alliances have empowered European companies to enhance their competitive positions on the global stage while concurrently fostering creative synergy among their teams. This comprehensive review not only contributes to the theoretical understanding of strategic alliances and creative synergy but also offers practical insights for businesses navigating the collaborative landscape within the EuroSphere. As we unravel the complexities of these alliances, we uncover valuable lessons and opportunities for future research, providing a roadmap for those seeking to harness the full potential of strategic collaborations in the dynamic European context. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=European%20Union" title="European Union">European Union</a>, <a href="https://publications.waset.org/abstracts/search?q=strategic%20alliances" title=" strategic alliances"> strategic alliances</a>, <a href="https://publications.waset.org/abstracts/search?q=creative%20synergy" title=" creative synergy"> creative synergy</a>, <a href="https://publications.waset.org/abstracts/search?q=competitiveness" title=" competitiveness"> competitiveness</a> </p> <a href="https://publications.waset.org/abstracts/179685/strategic-alliances-and-creative-synergy-within-european-union-a-theoretical-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179685.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">66</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> Effect of Foot Reflexology Treatment on Arterial Blood Gases among Mechanically Ventilated Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20Salah%20Abdullah%20Ismail">Maha Salah Abdullah Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Manal%20S.%20Ismail"> Manal S.

It is a widely recognized as an alternative therapy, effective for many health conditions. This study aimed to evaluate the effect of reflexology treatment on arterial blood gases among mechanically ventilated patients. A quasi-experimental (pre and post-test) research design was used. Research hypothesis was mechanically ventilated patients who will receive the reflexology treatment will have improvement in their arterial blood gases than those who will not. The current study was carried out in different Intensive Care Units at the Cairo University Hospitals. A purposeful sample of 100 adults’ mechanically ventilated patients was recruited over a period of three months of data collection. The participants were divided into two equally matched groups; (1) The study group who has received the routine care, in addition, two reflexology sessions on the feet, (2) The control group who has received only the routine care. One tool was utilized to collect data pertinent to the study; mechanically ventilated patients' data sheet that consists of demographic and medical data. Result: Majority (58% of the study group and 82% of the control group) were males, with mean age of 50.9 years in both groups. Patients who received the reflexology treatment significantly increase in the oxygen saturation pre second session (t=5.15, p=.000), immediate post sessions (t=4.4, p=.000) and post two hours (t= 4.7, p= .000). The study group was more likely to have lower PaO2 (F=5.025, p=.015), PaCo2 (F=4.952, p=.025) and higher HCo3 (F=15.211, p=.000) than the control group. Conclusion: This study results support the positive effect of reflexology treatment in improving some arterial blood gases among mechanically ventilated patients’ with the conventional therapy as in the study group there was increase in the oxygen saturation. In differences between groups there decrease PaO2, PaCo2 and increase HCo3 in the study group. Recommendation: Nurses should be trained how to demonstrate the foot reflexology among mechanically ventilated patients. <p class="card-text"><strong>Keywords:</strong> <a
