contents of tomato (Solanum lycopersicum) fruits were studied. The study was conducted separately on two different cultivar varieties of tomato, namely Supermarmande and UC82B. The results indicated that the presence of the PGPR almost doubled the average yield per plant. There was a significant improvement in the pomological qualities of the PGPR treated tomato fruits compared to the corresponding healthy treatments especially in traits such as the average fruit weight, height, and fruit volume. The chemical analysis of tomato fruits revealed that the presence of the PGPRs increased the total protein, lycopene, alkalinity and phenol content of the tomato fruits compared to the healthy controls. They had no influence on the reduced sugar, total soluble solids or the titerable acid content of fruits. However their presence reduced the amount of ascorbic acid in tomato fruits compared to the healthy controls. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PGPR" title="PGPR">PGPR</a>, <a href="https://publications.waset.org/abstracts/search?q=tomato" title=" tomato"> tomato</a>, <a href="https://publications.waset.org/abstracts/search?q=fruit%20quality" title=" fruit quality"> fruit quality</a> </p> <a href="https://publications.waset.org/abstracts/29728/effects-of-plant-growth-promoting-rhizobacteria-on-the-yield-and-nutritive-quality-of-tomato-fruits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29728.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">328</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">59</span> Soliton Solutions in (3+1)-Dimensions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Magdy%20G.%20Asaad">Magdy G.

In growing business organizations, entrepreneurship expands its conceptualization. It reveals itself through new business creation in the active organization, through <em>renewal, change, innovation, creation and development</em> of current organization, through breaking and changing of established rules inside or outside the organization and becomes more flexible, adaptive and competitive, also improving effectiveness of organization activity. Therefore, the topic of entrepreneurship, relates the creation of firms to personal / individual characteristics of the entrepreneurs and their social context. This paper is an empirical study, which aims to address these two gaps in the literature. For this endeavor, we use the latest available data from the Global Entrepreneurship Monitor (GEM) project. This data set is widely regarded as a unique source of information about entrepreneurial activity, as well as the aspirations and attitudes of individuals across a wide number of countries and territories worldwide. This paper tries to contribute to fill this gap, by exploring the key drivers of innovative entrepreneurship in the tourism sector. Our findings are consistent with the existing literature in terms of the individual characteristics of entrepreneurs, but quite surprisingly we find an inverted U-shape relation between human development and innovative entrepreneurship in tourism sector. It has been revealed that tourism entrepreneurs are less likely to have innovative products, compared with entrepreneurs in medium developed countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GEM" title="GEM">GEM</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20development" title=" human development"> human development</a>, <a href="https://publications.waset.org/abstracts/search?q=innovative%20entrepreneurship" title=" innovative entrepreneurship"> innovative entrepreneurship</a>, <a href="https://publications.waset.org/abstracts/search?q=occupational%20choice" title=" occupational choice"> occupational choice</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism" title=" tourism"> tourism</a> </p> <a href="https://publications.waset.org/abstracts/49750/innovative-entrepreneurship-in-tourism-business-an-international-comparative-study-of-key-drivers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49750.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">258</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">56</span> Seamless Mobility in Heterogeneous Mobile Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohab%20Magdy%20Mostafa%20Mohamed">Mohab Magdy Mostafa Mohamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this paper is to introduce a vertical handover (VHO) algorithm between wireless LANs (WLANs) and LTE mobile networks.

The story is one of the most recognized phenomena as a sustainable solid growth and is considered a remarkable outcome for any destination. The competitive situation and challenges within the tourism industry worldwide entail a better understanding of the destination position and its image to achieve Oman’s aspiration to retain its international reputation as one of the most desirable destinations in the Middle East. To access general perceptions of Oman’s attributes, their importance and their influences among U.S. tourists, an online survey was conducted with 522 American travelers who have traveled internationally, including non-visitors, virtual-visitors and visitors to Oman. This research involved a total of 36 attributes in the survey. Participants were asked to rate their agreement on how each attribute represented Oman and how important each attribute was for selecting destinations on 5- point Likert Scale. They also indicated if each attribute has a positive, neutral or negative influence on their destination selection. Descriptive statistics and importance performance analysis (IPA) were conducted. IPA illustrated U.S. tourists’ perceptions of Oman’s destination attributes and their importance in destination selection on a matrix with four quadrants, divided by actual mean value in each grid for importance (M=3.51) and performance (M=3.57). Oman tourism organizations and destination managers may use these research findings for future marketing and management efforts toward the U.S. travel market. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analysis%20of%20importance" title="analysis of importance">analysis of importance</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=destination%20attributes" title=" destination attributes"> destination attributes</a>, <a href="https://publications.waset.org/abstracts/search?q=Oman%27s%20position" title=" Oman's position"> Oman's position</a>, <a href="https://publications.waset.org/abstracts/search?q=U.S.%20tourists" title=" U.S. tourists"> U.S. tourists</a> </p> <a href="https://publications.waset.org/abstracts/49595/omans-position-in-us-tourists-mind-the-use-of-importance-performance-analysis-on-destination-attributes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49595.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">54</span> Synthesis, Characterization and Applications of Hydrogels Based on Chitosan Derivatives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20H.%20Abu%20Elella">Mahmoud H.

The PC was mixed mechanically with ABS in 10%, 20%, 30%, 40%, and 50% by weight. The mechanical properties of pure ABS reinforced with PC were investigated using tensile, impact, hardness, and wear tests. The results showed that, by adding 10%, 20%, 30%, 40%, and 50% wt. of PC to the pure ABS, the ultimate tensile strength increased from 55 N/mm2 for neat ABS to 57 N/mm2 (i.e. 3.63%), 60 N/mm2 (i.e. 9.09%), 63 N/mm2 (i.e. 14.54%), 66 N/mm2 (i.e. 20%), 69 N/mm2 (i.e. 25.45%) respectively. Test results also revealed nearly 5.72% improvement in young's modulus by adding 10% of PC to ABS, 16.74% improvement by adding 20%, 23.34% improvement by adding 30%, 27.75% improvement by adding 40%, and no other increase in case of 50%. The impact test results showed that with the increase of the PC content, first, the impact strength decreased and then increased gradually. The impact strength decreased rapidly when the content of PC was 0% to 10% range. As well as, in the case of 20%, 30%, 40%, and 50% PC, the impact strength is increased. The hardness test results, using the Shore D tester, showed that, as the PC particles contents increased, the hardness increased from 76 for the ABS to 80 for 10% PC, and decreased to 79 for 20% PC, and then increased to 80 in case of 30%, 40%, and 50% PC. Wear test results showed that PC improves the wear resistance of ABS/PC blends. Positron annihilation lifetime spectroscopy showed that with an increase of PC in ABS/PC blends, a slight decrease in free volume size and an increase in the tensile strength due to good adhesion between PC and ABS matrix, which acted as an advantage in the polymer matrix. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ABS" title="ABS">ABS</a>, <a href="https://publications.waset.org/abstracts/search?q=PC" title=" PC"> PC</a>, <a href="https://publications.waset.org/abstracts/search?q=injection%20molding%20process" title=" injection molding process"> injection molding process</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=lifetime%20spectroscopy" title=" lifetime spectroscopy"> lifetime spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/163599/investigation-of-mechanical-properties-and-positron-annihilation-lifetime-spectroscopy-of-acrylonitrile-butadiene-styrenepolycarbonate-blends" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163599.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">73</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">52</span> Real Activities Manipulation vs. Accrual Earnings Management: The Effect of Political Risk</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Heba%20Abdelmotaal">Heba Abdelmotaal</a>, <a href="https://publications.waset.org/abstracts/search?q=Magdy%20Abdel-Kader"> Magdy Abdel-Kader</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: This study explores whether a firm’s effective political risk management is preventing real and accrual earnings management .

Originality/value: This paper provides a statistically evidence on the effects of the political risk management failure on the mangers’ engagement in the real and accrual earnings management practices, and its impact on the firm’s performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=political%20risk" title="political risk">political risk</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management%20failure" title=" risk management failure"> risk management failure</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20activities%20manipulation" title=" real activities manipulation"> real activities manipulation</a>, <a href="https://publications.waset.org/abstracts/search?q=accrual%20earnings%20management" title=" accrual earnings management"> accrual earnings management</a> </p> <a href="https://publications.waset.org/abstracts/32461/real-activities-manipulation-vs-accrual-earnings-management-the-effect-of-political-risk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32461.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">439</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> Vehicle to Vehicle Communication: Collision Avoidance Scenarios</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Emad">Ahmed Emad</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Salah"> Ahmed Salah</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelrahman%20Magdy"> Abdelrahman Magdy</a>, <a href="https://publications.waset.org/abstracts/search?q=Omar%20Rashid"> Omar Rashid</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Adel"> Mohammed Adel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research paper discusses vehicle-to-vehicle technology as an important application of linear algebra. This communication technology represents an efficient and promising application to help to ensure the safety of the drivers by warning them when a crash possibility is close. The major link that combines our topic with linear algebra is the Laplacian matrix. Some main definitions used in the V2V were illustrated, such as VANET and its characteristics. The V2V technology could be applied in different applications with different traffic scenarios and various ways to warn car drivers. These scenarios were simulated programs such as MATLAB and Python to test how the V2V system would respond to the different scenarios and warn the car drivers exposed to the threat of collisions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=V2V%20communication" title="V2V communication">V2V communication</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle%20to%20vehicle%20scenarios" title=" vehicle to vehicle scenarios"> vehicle to vehicle scenarios</a>, <a href="https://publications.waset.org/abstracts/search?q=VANET" title=" VANET"> VANET</a>, <a href="https://publications.waset.org/abstracts/search?q=FCW" title=" FCW"> FCW</a>, <a href="https://publications.waset.org/abstracts/search?q=EEBL" title=" EEBL"> EEBL</a>, <a href="https://publications.waset.org/abstracts/search?q=IMA" title=" IMA"> IMA</a>, <a href="https://publications.waset.org/abstracts/search?q=Laplacian%20matrix" title=" Laplacian matrix"> Laplacian matrix</a> </p> <a href="https://publications.waset.org/abstracts/156914/vehicle-to-vehicle-communication-collision-avoidance-scenarios" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156914.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">163</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> A New Approach to the Digital Implementation of Analog Controllers for a Power System Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Shabib">G.

The new method utilizes the Plant Input Mapping (PIM) algorithm. The proposed algorithm is stable for any sampling rate, as well as it takes the closed loop characteristic into consideration.

Then an accurate fault classifier and locator algorithm was designed, trained and tested using current samples only. The results obtained from ANFIS output were compared with the real output. From the results, it was found that the percentage error between ANFIS output and real output is less than three percent.

Therefore, translation of the Qur’an is inevitably nothing but a translation of the interpretation of the meanings of the Qur’an. It requires special competencies and skills for translators so that they can get close to the intended meaning of the verse of the Qur’an and convey it with precision. In the Arabic language, the verbal noun “AlMasdar” is a very important derivative that properly expresses the verbal idea in the form of a noun. It sounds the same as the base form of the verb with minor changes in the vowel pattern. It is one of the important topics in morphology. The morphologists divided verbal nouns into auditory and analogical, and they stated that that the verbal nouns (Masadars) originating from three-letter verbs are auditory, although they set controls for some of them in order to preserve them. As for the lexicographers, they mentioned the verbal nouns while talking about the lexical materials, and in some cases, their explanation of them exceeded that made by the morphologists, especially in their discussion of structures that the morphologists did not refer to in their books. The verb kafara (disbelief), for example, has three patterns, namely: al-kufْr, al-kufrān, and al-kufūr, and it was mentioned in the Holy Qur’an with different connotations. The verb ṣāma (fasted) with his two patterns (al-ṣaūm and al-ṣīām) was mentioned in the Holy Qur’an while their semantic meaning is different. The problem discussed in this research paper lied in the "linguistic loss" committed by translators when dealing with Islamic religious texts, especially the Qur'an. The study tried to identify the strategy adopted by translators of the Holy Qur'an in translating words that were classified as verbal nouns through analyzing the translation rendered by five translations of the Qur’an into English: Yusuf Ali, Pickthall, Mohsin Khan, Muhammad Sarwar, and Shakir. This study was limited to the verbal nouns in the Quraan that originate from three-letter verbs and have different semantic meanings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pattern" title="pattern">pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=three-letter%20verbs" title=" three-letter verbs"> three-letter verbs</a>, <a href="https://publications.waset.org/abstracts/search?q=translation%20of%20the%20Quran" title=" translation of the Quran"> translation of the Quran</a>, <a href="https://publications.waset.org/abstracts/search?q=verbal%20nouns" title=" verbal nouns"> verbal nouns</a> </p> <a href="https://publications.waset.org/abstracts/144930/translation-of-the-verbal-nouns-masadars-originating-from-three-letter-verbs-in-the-holy-quran-verbal-noun-with-more-than-one-pattern-wazn-as-a-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144930.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">47</span> A Holistic Study of the Beta Lyrae Systems V0487 Lac, V0566 Hya and V0666 Lac</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moqbil%20S.%20Alenazi">Moqbil S.

A windows interface version of the Wilson and Devinney code (W-D) based on model atmospheres and a pass band prescription have been used for the radiative treatment. The accepted models reveal some absolute parameters for the studied systems, which are used in adopting the spectral type of the system's components and their evolutionary status. Distances to each system were calculated, and physical properties were estimated.

The primary purpose of this paper is the adaptive stress effect on dietary behavior, which is directly correlated with changes in plasma cortisol levels. Physiological factors have a role in systems of adaptation and stress. Objectives: Ten clinically healthy cats were included in the study, and they were all kept in the same setting. Methods: On days 1, 5, 9, and 10 of the stay, each cat's behavior was observed through ethograms, and the serum cortisol levels were also measured at the same time. Significant behavioral changes in terms of nutrition were seen on the first day, with 50% of the participants not feeding and all participants not watering. Toward the study's conclusion, between days 5 and 9, there were no longer any discernible changes in the dietary habits, which might be attributed to the adaptation to the new living conditions. Cortisol variations in serological levels were consistent with behavioral changes; in 50% of the participants under observation, there was a substantial increase in values (p<0.05), which gradually declined as the study came to an end. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=domestic%20cats" title="domestic cats">domestic cats</a>, <a href="https://publications.waset.org/abstracts/search?q=ewes" title=" ewes"> ewes</a>, <a href="https://publications.waset.org/abstracts/search?q=nutritional%20behavior" title=" nutritional behavior"> nutritional behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=adjustment%20stress" title=" adjustment stress"> adjustment stress</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20cortisol%20levels" title=" plasma cortisol levels"> plasma cortisol levels</a> </p> <a href="https://publications.waset.org/abstracts/187021/a-study-on-how-domestic-cats-nutritional-behavior-is-affected-by-adjustment-stress" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187021.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">41</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> Banking and Accounting Analysis Researches Effect on Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marina%20Magdy%20Naguib%20Karas">Marina Magdy Naguib Karas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> New methods of providing banking services to the customer have been introduced, such as online banking. Banks have begun to consider electronic banking (e-banking) as a way to replace some traditional branch functions by using the Internet as a new distribution channel. Some consumers have at least one account at multiple banks and access these accounts through online banking. To check their current net worth, clients need to log into each of their accounts, get detailed information, and work toward consolidation. Not only is it time-consuming, but it is also a repeatable activity with a certain frequency. To solve this problem, the concept of account aggregation was added as a solution. Account consolidation in e-banking as a form of electronic banking appears to build a stronger relationship with customers. An account linking service is generally referred to as a service that allows customers to manage their bank accounts held at different institutions via a common online banking platform that places a high priority on security and data protection. The article provides an overview of the account aggregation approach in e-banking as a new service in the area of e-banking. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compatibility" title="compatibility">compatibility</a>, <a href="https://publications.waset.org/abstracts/search?q=complexity" title=" complexity"> complexity</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20banking" title=" mobile banking"> mobile banking</a>, <a href="https://publications.waset.org/abstracts/search?q=observation" title=" observation"> observation</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20banking%20technology" title=" risk banking technology"> risk banking technology</a>, <a href="https://publications.waset.org/abstracts/search?q=Internet%20banks" title=" Internet banks"> Internet banks</a>, <a href="https://publications.waset.org/abstracts/search?q=modernization%20of%20banks" title=" modernization of banks"> modernization of banks</a>, <a href="https://publications.waset.org/abstracts/search?q=banks" title=" banks"> banks</a>, <a href="https://publications.waset.org/abstracts/search?q=account%20aggregation" title=" account aggregation"> account aggregation</a>, <a href="https://publications.waset.org/abstracts/search?q=security" title=" security"> security</a>, <a href="https://publications.waset.org/abstracts/search?q=enterprise%20development" title=" enterprise development"> enterprise development</a> </p> <a href="https://publications.waset.org/abstracts/185124/banking-and-accounting-analysis-researches-effect-on-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185124.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">44</span> Control of Microbial Pollution Using Biodegradable Polymer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20H.%20Abu%20Elella">Mahmoud H.

It is resulted by pathogenic microorganisms such as Escherichia coli (E. coli), Staphylococcus aureus (S. aureus) and other pathogenic strains. They cause a dangerous effect on human health, so great efforts have been exerted to produce new and effective antimicrobial agents. Nowadays, natural polysaccharides, such as chitosan and its derivatives are used as antimicrobial agents. The aim of our work is to synthesize of a biodegradable polymer such as N-quaternized chitosan (NQC) then Characterization of NQC by using different analysis techniques such as Fourier transform infrared (FTIR) and Scanning electron microscopy (SEM) and using it as an antibacterial agent against different pathogenic bacteria. Methods: Synthesis of NQC using dimethylsulphate. Results: FTIR technique exhibited absorption peaks of NQC, SEM images illustrated that surface of NQC was smooth and antibacterial results showed that NQC had a high antibacterial effect. Discussion: NQC was prepared and it was proved by FTIR technique and SEM images antibacterial results exhibited that NQC was an antibacterial agent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20agent" title="antimicrobial agent">antimicrobial agent</a>, <a href="https://publications.waset.org/abstracts/search?q=N-quaternized%20chitosan%20chloride" title=" N-quaternized chitosan chloride"> N-quaternized chitosan chloride</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20nanocomposites" title=" silver nanocomposites"> silver nanocomposites</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20polyacrylate" title=" sodium polyacrylate"> sodium polyacrylate</a> </p> <a href="https://publications.waset.org/abstracts/58758/control-of-microbial-pollution-using-biodegradable-polymer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58758.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">288</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> Nanoindentation Behavior and Physical Properties of Polyvinyl Chloride /Styrene Co-Maleic Anhydride Blend Reinforced by Nano-Bentonite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dalia%20Elsawy%20Abulyazied">Dalia Elsawy Abulyazied</a>, <a href="https://publications.waset.org/abstracts/search?q=Samia%20Mohamad%20Mokhtar"> Samia Mohamad Mokhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Magdy%20Motawie"> Ahmed Magdy Motawie </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article studies the effects of nano-bentonite on the structure and properties of polymer blends nanocomposites, based on polyvinyl chloride (PVC) and styrene co-maleic anhydride (SMA) blend. Modification of Egyptian bentonite (EB) is carried out using organo-modifier namely; octadecylamine (ODA). Octadecylamine bentonite (ODA-B) is characterized using FTIR, XRD and TEM. Nanocomposites of PVC/SMA/ODA-B are prepared by solution intercalation polymerization from 0.50 up to 5 phr. The nanocomposites are characterized by XRD and TEM. Thermal behavior of the nanocomposites is studied. The effect of different content of ODA-B on the nano-mechanical properties is investigated by a nano-indentation test method. Also the swelling and electrical properties of the nanocomposites are measured. The morphology of the nanocomposites shows that ODA-B achieved good dispersion in the PVC/SMA matrix. The thermal stability of the nanocomposites is enhanced due to the presence of the ODA-B. Incorporation of 0.5, 1, 3 and 5 phr. ODA-B into the PVC/SMA blends results in an improvement in nano-hardness of 16%, 76%, 92%, and 68% respectively. The elastic modulus increased by 37% from 4.59 GPa for unreinforced PVC/SMA blend to 6.30 GPa for 3 phr. The cross-link density and the electrical conductivity of the nanocomposites are increased with increasing the content of ODA-B. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PVC" title="PVC">PVC</a>, <a href="https://publications.waset.org/abstracts/search?q=SMA" title=" SMA"> SMA</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposites" title=" nanocomposites"> nanocomposites</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-bentonite" title=" nano-bentonite"> nano-bentonite</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoindentation" title=" nanoindentation"> nanoindentation</a>, <a href="https://publications.waset.org/abstracts/search?q=crosslink%20density" title=" crosslink density"> crosslink density</a> </p> <a href="https://publications.waset.org/abstracts/23611/nanoindentation-behavior-and-physical-properties-of-polyvinyl-chloride-styrene-co-maleic-anhydride-blend-reinforced-by-nano-bentonite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23611.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">482</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> Flood Monitoring in the Vietnamese Mekong Delta Using Sentinel-1 SAR with Global Flood Mapper</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20S.%20Afifi">Ahmed S.

The GFM enables the users to adjust manually the flood map parameters, e.g., the threshold for Z-value for VV and VH bands and the elevation and slope mask threshold. The composite R:G:B image results by coupling the bands of Sentinel-1 (VH:VV:VH) reduces false classification to a large extent compared to using one separate band (e.g., VH polarization band). The flood mapping algorithm in the GFM and the Otsu thresholding are compared with Sentinel-2 optical data. And the results show that the GFM algorithm can overcome the misclassification of a flooded area in An Giang, Vietnam. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SAR%20backscattering" title="SAR backscattering">SAR backscattering</a>, <a href="https://publications.waset.org/abstracts/search?q=Sentinel-1" title=" Sentinel-1"> Sentinel-1</a>, <a href="https://publications.waset.org/abstracts/search?q=flood%20mapping" title=" flood mapping"> flood mapping</a>, <a href="https://publications.waset.org/abstracts/search?q=disaster" title=" disaster"> disaster</a> </p> <a href="https://publications.waset.org/abstracts/160125/flood-monitoring-in-the-vietnamese-mekong-delta-using-sentinel-1-sar-with-global-flood-mapper" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160125.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">105</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">41</span> ICT Training Programs in Tourism and Hospitality Institutes: An Analytical Study of Types, Effectiveness, and Graduate Perceived Importance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Magdy%20Abdel-Aleem%20Abdel-Ati%20Mayouf">Magdy Abdel-Aleem Abdel-Ati Mayouf</a>, <a href="https://publications.waset.org/abstracts/search?q=Islam%20Al%20Sayed%20Hussein%20Al%20Sayed"> Islam Al Sayed Hussein Al Sayed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Development of tourism and hospitality faculties' graduates is a key to the future health of hospitality and tourism sectors.

Cardiac glycosides of digitalis, bufa and squill. Structure of salicin, hesperidin and rutin. Glycosides are certain molecules in which a sugar part is bound to some other part. Glycosides play numerous important roles in living organisms. Formally, a glycoside is any molecule in which a sugar group is bonded through its anomeric carbon to another group and form glycosidic bonds via an O-glycosidic bond or an S-glycosidic bond; glycosides involving the latter are also called thioglycosides. The purpose: the addition of sugar be bonded to a non-sugar for the molecule to qualify as a glycoside, The sugar group is then known as the glycone and the non-sugar group as the aglycone or genin part of the glycoside. The glycone can consist of a single sugar group (monosaccharide) or several sugar groups (oligosaccharide). The glycone and aglycone portions can be chemically separated by hydrolysis in the presence of acid. Methods: There are also numerous enzymes that can form and break glycosidic bonds. Results: The most important cleavage enzymes are the glycoside hydrolases, and the most important synthetic enzymes in nature are glycosyltransferases. Mutant enzymes termed glycosynthases have been developed that can form glycosidic bonds. Conclusions: There are a great many ways to chemically synthesize glycosidic bonds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glycosides" title="glycosides">glycosides</a>, <a href="https://publications.waset.org/abstracts/search?q=bufa" title=" bufa"> bufa</a>, <a href="https://publications.waset.org/abstracts/search?q=squill" title=" squill"> squill</a>, <a href="https://publications.waset.org/abstracts/search?q=thioglycosides" title=" thioglycosides"> thioglycosides</a> </p> <a href="https://publications.waset.org/abstracts/184292/vii-phytochemistry-unit-iv-glycoside" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184292.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">61</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> Influences of Island Characteristics on Plant Community Structure of Farasan Archipelago, Saudi Arabia: Island Biogeography and Nested Pattern</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalid%20Al%20Mutairi">Khalid Al Mutairi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mashhor%20Mansor"> Mashhor Mansor</a>, <a href="https://publications.waset.org/abstracts/search?q=Magdy%20El-Bana"> Magdy El-Bana</a>, <a href="https://publications.waset.org/abstracts/search?q=Saud%20L.%20Al-Rowaily"> Saud L.

A total of 191 species belonging to 129 genera and 53 families were identified. Following island biogeography theory, total plant species richness and their ecological groups were positively influenced by island size, number of habitats,elevation and were not affected by isolation. The high level of nestedness, the strong effect of area on total plant species richness and ecological groups, and the similarity of vegetation composition on the islands has several implications for conservation. In conclusion the large and richest islands in Farasan Archipelago such as Farasan Alkbir would conserve higher diversity than several smaller islands. This island also includes rare habitats like coral rocks and rare species. The invasion of the unique habitats such as wadi channels and water catchments in this island by the exotic tree Prosopis juliflora should be managed to conserve the native biodiversity. The protection of such critical habitats is very important on the other large island (e.g. Zufaf), due to their limited distribution in the country. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=island%20biogeography" title="island biogeography">island biogeography</a>, <a href="https://publications.waset.org/abstracts/search?q=conservation" title=" conservation"> conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=farasan%20archipelago" title=" farasan archipelago"> farasan archipelago</a>, <a href="https://publications.waset.org/abstracts/search?q=saudi%20arabia" title=" saudi arabia"> saudi arabia</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20diversity" title=" plant diversity"> plant diversity</a> </p> <a href="https://publications.waset.org/abstracts/28864/influences-of-island-characteristics-on-plant-community-structure-of-farasan-archipelago-saudi-arabia-island-biogeography-and-nested-pattern" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28864.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">346</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Effect of Erythropoietin Hormone Supplementation on Hypoxia-Inducible Factor1-Alpha in Rat Kidneys with Experimental Diabetic Nephropathy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20Deif">Maha Deif</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaa%20Eldin%20%20Hassan"> Alaa Eldin Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Eman%20Shaat"> Eman Shaat</a>, <a href="https://publications.waset.org/abstracts/search?q=Nesrine%20Elazhary"> Nesrine Elazhary</a>, <a href="https://publications.waset.org/abstracts/search?q=Eman%20Magdy"> Eman Magdy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Erythropoietin (EPO) is a hematopoietic factor with multiple protective effects. The aim of the present study was to investigate the potential effect of EPO administration on renal functions and hypoxia inducible factor 1-alpha (HIF-1a) in diabetic rat kidneys. Methodology: The current study was carried out on 40 male albino rats divided into four groups (n= 10 in each). Group I served as normal control, group II was the diabetic control, group III rats received EPO on the same day of diagnosis of diabetes mellitus (DM), while group IV received the first dose of EPO 2 weeks after the diagnosis of DM. Results: The results showed that EPO supplementation leads to a significant decrease in serum urea, urinary protein and creatinine clearance as well as a significant increase in renal HIF-1a in group III and IV rats compared to the diabetic control group (group II). However, fasting blood glucose was significantly decreased in group III as compared to the diabetic control group in the third week, but no significant difference was reported in the fourth week among groups II, III and IV. Conclusion: EPO administration leads to the improvement of renal functions and increased levels of HIF-1a in diabetic rats. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=erythropoietin" title="erythropoietin">erythropoietin</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetic%20nephropathy" title=" diabetic nephropathy"> diabetic nephropathy</a>, <a href="https://publications.waset.org/abstracts/search?q=hypoxia-inducible%20factor1-alpha" title=" hypoxia-inducible factor1-alpha"> hypoxia-inducible factor1-alpha</a>, <a href="https://publications.waset.org/abstracts/search?q=renal%20functions" title=" renal functions"> renal functions</a> </p> <a href="https://publications.waset.org/abstracts/52298/effect-of-erythropoietin-hormone-supplementation-on-hypoxia-inducible-factor1-alpha-in-rat-kidneys-with-experimental-diabetic-nephropathy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52298.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">286</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> Survey of Neonatologists’ Burnout on a Neonatal Surgical Unit: Audit Study from Cairo University Specialized Pediatric Hospital</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Tarek">Mahmoud Tarek</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaa%20Obeida"> Alaa Obeida</a>, <a href="https://publications.waset.org/abstracts/search?q=Mai%20Magdy"> Mai Magdy</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalid%20Hussein"> Khalid Hussein</a>, <a href="https://publications.waset.org/abstracts/search?q=Aly%20Shalaby"> Aly Shalaby</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: More doctors are complaining of burnout than before, Burnout is a state of physical and mental exhaustion caused by the doctor’s lifestyle, unfortunately, Medical errors are also more likely in those suffering from burnout and these may result in malpractice suits. Methodology: It is a retrospective audit of burnout response on all neonatologists over a 9 months period. We gathered data using burnout questionnaire, it was obtained from 23 physicians, the physicians divided into 5 categories according to the final score of the 28 questions in the questionnaire. Category 1 with score from 28-38 with almost no work stress, category 2 with score (38-50) who express a low amount of job related stress, category 3 with score (51-70) with moderate amount of stress, category 4 with score (71-90) those express a high amount of job stress and begun to burnout, category 5 with score (91 and above) who are under a dangerous amount of stress and advanced stage of burnout. Results: 33 neonatologists have received the questionnaire, 23 responses were sent back with a response rate of 69.6%. The results showed that 61% of physicians fall in category 4, 31% of the physician in category 5, while 8% of physicians equally distributed between category 2 and 3 (4% each of them). On the other hand, there is no physician present in category 1. Conclusion: Burnout is prevalent in SNICUs, So interventions to minimize burnout prevalence may be of greater importance as this may be reflected indirectly on medical conditions of the patients and physicians, efforts should be done to decrease this high rate of burnout. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cairo" title="Cairo">Cairo</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20overload" title=" work overload"> work overload</a>, <a href="https://publications.waset.org/abstracts/search?q=exhaustion" title=" exhaustion"> exhaustion</a>, <a href="https://publications.waset.org/abstracts/search?q=surgery" title=" surgery"> surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=neonatal%20ICU" title=" neonatal ICU"> neonatal ICU</a> </p> <a href="https://publications.waset.org/abstracts/93428/survey-of-neonatologists-burnout-on-a-neonatal-surgical-unit-audit-study-from-cairo-university-specialized-pediatric-hospital" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93428.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">213</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Evaluation of the Practice of Veterinary Pharmacy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Magdy%20Danial%20Riad">Maria Magdy Danial Riad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: In the United Kingdom (UK), pharmacists' roles have expanded considerably in recent decades to encompass clinical practice through more direct patient care. However, dispensing and compounding remain core activities for pharmacists. A lack of marketed preparations for species-specific animal use results in veterinary pharmacy practice compounding, retaining its prominence. Current participation by pharmacists to support this sphere of practice would appear to be minimal. Objectives: This study was undertaken to determine the opinions and views toward the practice of veterinary pharmacy by a cross-sectional group of pharmacists. Methods: Research data were collected via a self-administered survey questionnaire distributed at the 2012 annual conference of the Royal Pharmaceutical Society. Sampling was purposive, with a random distribution of the questionnaire to pharmacists during the conference sessions. Key findings: Interaction by pharmacists with veterinary pharmacies is currently minimal, primarily due to a lack of knowledge of veterinary medicines. Respondents revealed a lack of veterinary pharmacy courses during their undergraduate studies. This has led to situations where some veterinary prescriptions are dispensed without adequate checks being performed by the pharmacist. Pharmacists, on occasion, do not dispense veterinary prescriptions presented to them due to insufficient knowledge of veterinary medicines and/or a lack of consultable reference sources. The effect on practice is that pharmacists do not always participate as fully as would seem logical. Conclusions: Pharmacists' participation in veterinary pharmacy is limited by a lack of knowledge of veterinary medicines, mostly resulting from inadequate tuition on veterinary pharmacy during their initial education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=veterinary%20pharmacy" title="veterinary pharmacy">veterinary pharmacy</a>, <a href="https://publications.waset.org/abstracts/search?q=veterinary%20medicines" title=" veterinary medicines"> veterinary medicines</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmacy%20education" title=" pharmacy education"> pharmacy education</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmacists%20continuing%20professional%20development" title=" pharmacists continuing professional development"> pharmacists continuing professional development</a> </p> <a href="https://publications.waset.org/abstracts/166835/evaluation-of-the-practice-of-veterinary-pharmacy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166835.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">83</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">35</span> Patient Service Improvement in Public Emergency Department Using Discrete Event Simulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dana%20Mohammed">Dana Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatemah%20Abdullah"> Fatemah Abdullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Hawraa%20Ali"> Hawraa Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Najat%20Al-Shaer"> Najat Al-Shaer</a>, <a href="https://publications.waset.org/abstracts/search?q=Rawan%20Al-Awadhi"> Rawan Al-Awadhi</a>, <a href="https://publications.waset.org/abstracts/search?q="></a>, <a href="https://publications.waset.org/abstracts/search?q=Magdy%20Helal">Magdy Helal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We study the patient service performance at the emergency department of a major Kuwaiti public hospital, using discrete simulation and lean concepts. In addition to the common problems in such health care systems (over crowdedness, facilities planning and usage, scheduling and staffing, capacity planning) the emergency department suffered from several cultural and patient behavioural issues. Those contributed significantly to the system problems and constituted major obstacles in maintaining the performance in control. This led to overly long waiting times and the potential of delaying providing help to critical cases. We utilized the visual management tools to mitigate the impact of the patients’ behaviours and attitudes and improve the logistics inside the system. In addition a proposal is made to automate the date collection and communication within the department using RFID-based barcoding system. Discrete event simulation models were developed as decision support systems; to study the operational problems and assess achieved improvements. The simulation analysis resulted in cutting the patient delays to about 35% of their current values by reallocating and rescheduling the medical staff. Combined with the application of the visual management concepts, this provided the basis to improving patient service without any major investments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=simulation" title="simulation">simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20management" title=" visual management"> visual management</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20care%20system" title=" health care system"> health care system</a>, <a href="https://publications.waset.org/abstracts/search?q=patient" title=" patient "> patient </a> </p> <a href="https://publications.waset.org/abstracts/24792/patient-service-improvement-in-public-emergency-department-using-discrete-event-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24792.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">475</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> Cheiloscopy and Dactylography in Relation to ABO Blood Groups: Egyptian vs. Malay Populations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manal%20Hassan%20Abdel%20Aziz">Manal Hassan Abdel Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Mohamed%20Magdy%20Badr%20El%20Dine"> Fatma Mohamed Magdy Badr El Dine</a>, <a href="https://publications.waset.org/abstracts/search?q=Nourhan%20Mohamed%20Mohamed%20Saeed"> Nourhan Mohamed Mohamed Saeed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Establishing association between lip print patterns and those of fingerprints as well as blood groups is of fundamental importance in the forensic identification domain. The first aim of the current study was to determine the prevalent types of ABO blood groups, lip prints and fingerprints patterns in both studied populations. Secondly, to analyze any relation found between the different print patterns and the blood groups, which would be valuable in identification purposes. The present study was conducted on 60 healthy volunteers, (30 males and 30 females) from each of the studied population. Lip prints and fingerprints were obtained and classified according to Tsuchihashi's classification and Michael Kuchen’s classification, respectively. The results show that the ulnar loop was the most frequent among both populations. Blood group A was the most frequent among Egyptians, while blood groups O and B were the predominant among Malaysians. Significant relations were observed between lip print patterns and fingerprint (in the second quadrant for Egyptian males and the first one for Malaysian). For Malaysian females, a statistically significant association was proved in the fourth quadrant. Regarding the blood groups, 89.5% of ulnar loops were significantly related to blood group A among Egyptian males. The results proved an association between the fingerprint pattern and the lip prints, as well as between the ABO blood group and the pattern of fingerprints. However, further researches with larger sample sizes need to be directed to approve the current results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ABO" title="ABO">ABO</a>, <a href="https://publications.waset.org/abstracts/search?q=cheiloscopy" title=" cheiloscopy"> cheiloscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=dactylography" title=" dactylography"> dactylography</a>, <a href="https://publications.waset.org/abstracts/search?q=Egyptians" title=" Egyptians"> Egyptians</a>, <a href="https://publications.waset.org/abstracts/search?q=Malaysians" title=" Malaysians"> Malaysians</a> </p> <a href="https://publications.waset.org/abstracts/100037/cheiloscopy-and-dactylography-in-relation-to-abo-blood-groups-egyptian-vs-malay-populations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100037.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">219</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> Effects of Monofin Training on Left Ventricular Performance in Elite Egyptian Children Athletes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Magdy%20Abouzeid">Magdy Abouzeid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: The aim of this study was to examine the influence of Monofin training, 36 weeks, 6 times per week, 90 min/unit on left ventricular performance in elite Egyptian Monofin athletes.

The alloying elements will be added at different levels using the factorial design of experiments of 2<sup>2</sup>; the two factors are Mg and Ag at two levels of concentration. The superior mechanical properties of the produced Al-Cu-Mg-Ag alloys after aging will be resulted from a unique type of precipitation named as Ω-phase. The formed precipitate enhanced the tensile strength and thermal stability. This paper further investigated the microstructure and mechanical properties of as cast Al–Cu–Mg–Ag alloys after being complete homogenized treatment at 520 °C for 8 hours followed by isothermally age hardening process at 190 °C for different periods of time. The homogenization at 520 °C for 8 hours was selected based on homogenization study at various temperatures and times. The alloys’ microstructures were studied by using optical microscopy (OM). In addition to that, the fracture surface investigation was performed using a scanning electronic microscope (SEM). Studying the microstructure of aged Al-Cu-Mg-Ag alloys reveal that the grains are equiaxed with an average grain size of about 50 µm. A detailed fractography study for fractured surface of the aged alloys exhibited a mixed fracture whereby the random fracture suggested crack propagation along the grain boundaries while the dimples indicated that the fracture was ductile. The present result has shown that alloy 5 has the highest hardness values and the best mechanical behaviors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=precipitation%20hardening" title="precipitation hardening">precipitation hardening</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminum%20alloys" title=" aluminum alloys"> aluminum alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=aging" title=" aging"> aging</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20of%20experiments" title=" design of experiments"> design of experiments</a>, <a href="https://publications.waset.org/abstracts/search?q=analysis%20of%20variance" title=" analysis of variance"> analysis of variance</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20treatments" title=" heat treatments"> heat treatments</a> </p> <a href="https://publications.waset.org/abstracts/102070/a-study-on-the-effect-of-mg-and-ag-additions-and-age-hardening-treatment-on-the-properties-of-as-cast-al-cu-mg-ag-alloys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102070.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">31</span> Effect of Many Levels of Undegradable Protein on Performance, Blood Parameters, Colostrum Composition and Lamb Birth Weight in Pregnant Ewes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Magdy%20Danial%20Riad">Maria Magdy Danial Riad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study was to investigate the effect of different protein sources with different degradability ratios during late gestation of ewes on colostrum composition and its IgG concentration, body weight change of dams, and birth weight of their lambs. Objectives: 35 multiparous native crossbred ewes (BW= 59±2.5kg) were randomly allocated to five dietary treatments (7 ewes / treatment) for 2 months prior to lambing. Methods: Experimental diets were isonitrogenous (12.27% CP) and isocaloric (2.22 Mcal ME/kg DM). In diet I (the control), solvent extract soybeans (SESM 33% RUP of CP), II feed grade urea (FGU 31% RUP), III slow release urea (SRU 31% RUP). As sources of undegradable protein, extruded expeller SBM-EESM 40 (37% RUP) and extruded expeller SBM-EESM 60 (41% RUP) were used in groups IV and V, respectively. Results showed no significant effect on feed intake, crude protein (CP), metabolizable energy (ME), and body condition score (BCS). Ewes fed the 37% RUP diet gained more (p<0.05) weight compared with ewes fed the 31% RUP diet (5.62 vs. 2.5kg). Ewes in EESM 60 had the highest levels of fat, protein, total solid, solid not fat, and immunoglobulin and the lowest in urea N content (P< 0.05) in colostrum during the first 24hrs after lambing. Conclusions: Protein source and RUP levels in ewes’ diets had no significant effect (P< 0.05) on lambs’ birth weight and ewes' blood biochemical parameters. Increasing the RUP content of diet during late gestation resulted in an increase in colostrum constituents and its IgG level but had no effect on ewes’ performance and their lambs’ outcome. <p
