These polyesters were synthesized by interfacial polycondensation technique of 3,5-bis(4-hydroxybenzylidene)-1-methyl-4-piperidone (I) and 3,5-bis(4-hydroxy-3-methoxy benzyli-dene)-1-methyl-4-piperidone (II) with terphthaloyl, isophthaloyl, 4,4'-diphenic, adipoyl and sebacoyl dichlorides. The yield and the values of the reduced viscosity of the produced polyesters were found to be affected by the type of an organic phase. In order to characterize these polymers, the necessary model compounds (A), (B) were prepared from (I), (II) respectively and benzoyl chloride. The structure of monomers (I), (II), model compounds and resulting polyesters were confirmed by IR, elemental analysis and 1HNMR spectroscopy. The various characteristic of the resulting polymers including solubility, thermal properties, viscosity and X-ray analysis were also studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=synthesis" title="synthesis">synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20polyesters" title=" new polyesters"> new polyesters</a>, <a href="https://publications.waset.org/abstracts/search?q=chemistry" title=" chemistry"> chemistry</a> </p> <a href="https://publications.waset.org/abstracts/5559/synthesis-and-characterization-of-new-polyesters-based-on-diarylidene-1-methyl-4-piperidone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5559.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">458</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">72</span> In Vivo Maltase and Sucrase Inhibitory Activities of Five Underutilized Nigerian Edible Fruits</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Auwal%20Ibrahim">Mohammed Auwal Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Isa%20Yunusa"> Isa Yunusa</a>, <a href="https://publications.waset.org/abstracts/search?q=Nafisa%20Kabir"> Nafisa Kabir</a>, <a href="https://publications.waset.org/abstracts/search?q=Shazali%20Ali%20Baba"> Shazali Ali Baba</a>, <a href="https://publications.waset.org/abstracts/search?q=Amina%20Muhammad%20Yushau"> Amina Muhammad Yushau</a>, <a href="https://publications.waset.org/abstracts/search?q=Suraj%20Suraj%20Ibrahim"> Suraj Suraj Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Zaharaddeen%20Idris%20Bello"> Zaharaddeen Idris Bello</a>, <a href="https://publications.waset.org/abstracts/search?q=Suleiman%20Haruna%20Suleiman"> Suleiman Haruna Suleiman</a>, <a href="https://publications.waset.org/abstracts/search?q=Murtala%20Bindawa%20Isah"> Murtala Bindawa Isah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Inhibition of intestinal maltase and sucrase prevents postprandial blood glucose excursions which are beneficial in ameliorating diabetes-associated complications. Objective: In this study, the inhibitory effects of fruit extracts of Parinari macrophylla, Detarium microcarpum, Ziziphus spina-christi, Z. mairei and Parkia biglobosa were investigated against intestinal maltase and sucrase. Methods: Rats were given co-administration of the fruit extracts with maltose or sucrose and blood glucose levels were measured at 0, 30, 90 and 120 min. Results: The glucose-time curves indicated that all the fruits had the most potent inhibitory effects on both maltase and sucrase within the first 30 min. The computed Area Under the Curves (AUC0-120)for all the fruits indicated more potent inhibitory effects against intestinal maltase than sucrase.The ED50 range for the fruits extract against maltase and sucrase were 647.15-1118.35 and 942.44-1851.94 mg/kg bw respectively. Conclusion: The data suggests that the fruits could prevent postprandial hyperglycemia via inhibition of intestinal maltase and sucrase. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabetes%20mellitus" title="diabetes mellitus">diabetes mellitus</a>, <a href="https://publications.waset.org/abstracts/search?q=fruits" title=" fruits"> fruits</a>, <a href="https://publications.waset.org/abstracts/search?q=%CE%B1-glucosidases" title=" α-glucosidases"> α-glucosidases</a>, <a href="https://publications.waset.org/abstracts/search?q=maltase" title=" maltase"> maltase</a>, <a href="https://publications.waset.org/abstracts/search?q=sucrase" title=" sucrase"> sucrase</a> </p> <a href="https://publications.waset.org/abstracts/43113/in-vivo-maltase-and-sucrase-inhibitory-activities-of-five-underutilized-nigerian-edible-fruits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43113.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">384</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">71</span> Effect of Fire on Structural Behavior of Normal and High Strength Concrete Beams </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alaa%20I.%20Arafa">Alaa I.

Despite all these successes, diagnoses and treatment of diseases have become complex. MYCIN is a groundbreaking illustration of a clinical decision support system (CDSS), which was developed to assist physicians in the diagnosis and treatment of bacterial infections by providing suggestions for antibiotic regimens. MYCIN was one of the earliest expert systems to demonstrate how CDSSs may assist human decision-making in complicated areas. Relevant databases were searched using google scholar, PubMed and general Google search, which were peculiar to clinical decision support systems. The articles were then screened for a comprehensive overview of the functionality, consultative style and statistical usage of MYCIN, a clinical decision support system. Inferences drawn from the articles showed some usage of MYCIN for problem-based learning among clinicians and students in some countries. Furthermore, the data demonstrated that MYCIN had completed clinical testing at Stanford University Hospital following years of research. The system (MYCIN) was shown to be extremely accurate and effective in diagnosing and treating bacterial infections, and it demonstrated how CDSSs might enhance clinical decision-making in difficult circumstances. Despite the challenges MYCIN presents, the benefits of its usage to clinicians, students and software developers are enormous. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clinical%20decision%20support%20system" title="clinical decision support system">clinical decision support system</a>, <a href="https://publications.waset.org/abstracts/search?q=MYCIN" title=" MYCIN"> MYCIN</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title=" diagnosis"> diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=bacterial%20infections" title=" bacterial infections"> bacterial infections</a>, <a href="https://publications.waset.org/abstracts/search?q=support%20systems" title=" support systems"> support systems</a> </p> <a href="https://publications.waset.org/abstracts/165608/a-script-for-presentation-to-the-management-of-a-teaching-hospital-on-mycin-a-clinical-decision-support-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165608.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">145</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">69</span> A Study on Weddernburn – Artin Theorem for Rings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fahad%20Suleiman">Fahad Suleiman</a>, <a href="https://publications.waset.org/abstracts/search?q=Sammani%20Abdullahi"> Sammani Abdullahi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study depicts that a Wedderburn Artin – theorem for rings is considered to be a semisimple ring R which is isomorphic to a product of finitely many mi by mi matrix rings over division rings Di, for some integers n_i, both of which are uniquely determined up to permutation of the index i.

Hospital Intensive Care Unit spaces pose a special challenge, where design guidelines requires the provision of external windows for day-lighting and external view. Window protection strategies could be employed to reduce energy loads without detriment effect on comfort or health care. This paper addresses the effectiveness of using various window strategies on the annual cooling, heating and lighting energy use of a typical Hospital Intensive Unit space. Series of experiments were performed using the EnergyPlus simulation software for a typical Intensive Care Unit (ICU) space in Cairo, located in the Egyptian desert. This study concluded that the use of shading systems is more effective in conserving energy in comparison with glazing of different types, in the Cairo ICUs. The highest energy savings in the West and South orientations were accomplished by external perforated solar screens, followed by overhangs positioned at a protection angle of 45°. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy" title="energy">energy</a>, <a href="https://publications.waset.org/abstracts/search?q=hospital" title=" hospital"> hospital</a>, <a href="https://publications.waset.org/abstracts/search?q=intensive%20care%20units" title=" intensive care units"> intensive care units</a>, <a href="https://publications.waset.org/abstracts/search?q=shading" title=" shading"> shading</a> </p> <a href="https://publications.waset.org/abstracts/2500/energy-efficient-shading-strategies-for-windows-of-hospital-icus-in-the-desert" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2500.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">289</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">67</span> Nigerian Foreign Policy: A Dancing Tune of the Western Powers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nura%20Suleiman">Nura Suleiman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The foreign policy of any country or nation is intended to promote and protect the country’s national interest.

The FL is condensed onto cellulose aldehyde using three diamine spacers (H₂N-NH₂, H₂N(CH₂)₂NH₂ and H₂N(CH₂)₃NH₂) to afford Cell=Spacer=FL. The obtained products were characterized by spectroscopic (FT-IR, UV–Vis), thermal gravimetric analysis (TGA), and microscopic (Optical, SEM) techniques. The UV-Vis spectra of the FL=N(CH₂)ₓNH₂ (x = 0, 2, 3) moieties show that they are transparent in the 375- 800 nm region while they exhibit intense absorption band below 350 nm attributed to n-π* and π-π* transitions. The solid-state photoluminescence (PLs-s) of the cold-pressed pellets of the FL=N(CH₂)ₓNH₂ and Cell=Spacer=FL placed in a quartz cuvette show strong emission in the 500-550 nm region upon irradiation with Xe lamp light (λex = 320 nm). The PLs-s green emission of the grafted Cell=Spacer=FL was evaluated relative to that of the FL-based precursor. These grafted conjugated products have the potential to be used as analyte sensors for typical nitroaromatics/aromatic amines and be further extended to immunoassay studies for aromatic amino acids such as phenylalanine and histidine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=luminescence" title="luminescence">luminescence</a>, <a href="https://publications.waset.org/abstracts/search?q=cellulose" title=" cellulose"> cellulose</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorenone" title=" fluorenone"> fluorenone</a>, <a href="https://publications.waset.org/abstracts/search?q=grafting" title=" grafting"> grafting</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20state" title=" solid state"> solid state</a> </p> <a href="https://publications.waset.org/abstracts/176946/solid-state-luminescence-of-fluorenone-grafted-onto-cellulose-aldehyde-backbone-using-different-organic-amine-spacers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176946.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">72</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">64</span> Population Dynamics of Auchenoglanis Occidentalis From Dadin-Kowa Dam, Gombe State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nazeef">Nazeef</a>, <a href="https://publications.waset.org/abstracts/search?q=Suleiman"> Suleiman</a>, <a href="https://publications.waset.org/abstracts/search?q=Umar"> Umar</a>, <a href="https://publications.waset.org/abstracts/search?q=Danladi%20Muhammad"> Danladi Muhammad</a>, <a href="https://publications.waset.org/abstracts/search?q=Ja%27afar%20Ali"> Ja'afar Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Zaliha%20Adamu%20Umar"> Zaliha Adamu Umar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The population dynamics of Auchenoglanis occidentalis from the Dadin-Kowa reservoir were studied.

The findings from the studies provide different results while some are of the view that board structure is related to firm performance, many empirical studies indicates no relationship. However, others found a U-shape relationship between firm performance and board structure.

It provides food for the ever rapidly increasing population and raw materials for the industries. People especially the rural dwellers are gainfully employed on their crop farms and small-scale livestock farms for income earning. In farming, availability of funds and time management are one of the major factors that influence the system of farming in Nigeria in which mathematical science knowledge was highly required in order for farms to be managed effectively. Farmers often applied mathematics, almost every day for a variety of tasks, ranging from measuring and weighing, to land marking. This paper, therefore, explores some of the ways math is used in farming. For instance, farmers use arithmetic variety of farm activities such as seed planting, harvesting crop, cultivation and mulching. It is also important in helping farmers to know how much their livestock weighs, how much milk their cows produce and crop yield per acres, among others. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agriculture" title="agriculture">agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=application" title=" application"> application</a>, <a href="https://publications.waset.org/abstracts/search?q=economic" title=" economic"> economic</a>, <a href="https://publications.waset.org/abstracts/search?q=farming" title=" farming"> farming</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematics" title=" mathematics"> mathematics</a> </p> <a href="https://publications.waset.org/abstracts/74574/application-of-mathematical-sciences-to-farm-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74574.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">247</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> State of Art in Software Requirement Negotiation Process Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shamsu%20Abdullahi">Shamsu Abdullahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nazir%20Yusuf"> Nazir Yusuf</a>, <a href="https://publications.waset.org/abstracts/search?q=Hazrina%20Sofian"> Hazrina Sofian</a>, <a href="https://publications.waset.org/abstracts/search?q=Abubakar%20Zakari"> Abubakar Zakari</a>, <a href="https://publications.waset.org/abstracts/search?q=Amina%20Nura"> Amina Nura</a>, <a href="https://publications.waset.org/abstracts/search?q=Salisu%20Suleiman"> Salisu Suleiman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Requirements negotiation process models help in resolving conflicting requirements of the heterogeneous stakeholders in the software development industry.

The customers of this move need their household stuff to be moved from their current house to the new one with minimum damage, in an organized manner, on time and with the minimum cost. Our goal was to improve the process between 10% and 20% time efficiency, 90% reduction in damaged parts and an acceptable improvement in the cost of the total move process. The expected ROI was 833%. Many improvement techniques have been used in terms of the way the boxes are prepared, their preparation cost, packing the goods, labeling them and moving them to a place for moving out.

Not only was it the first biographical film of late Egyptian president Gamal ‘Abdel Nasser (1918-1970); it also broke a long-accepted taboo against cinematic depiction of modern political leaders. Passionately received by Egyptians and Arabs throughout the world, the success of ‘Nasser 56’ empowered other filmmakers to follow Fadel’s suit. Interestingly, the three biographical films that followed had, completely or partially, a Nasser dimension. In addition to another biographical film of Nasser, Anwar al-Qawadri’s ‘Gamal ‘Abdel Nasser’ (1999); Muhammad Khan’s ‘Ayyam al-Sadat (Days of Sadat)’ (2001), and Sherif Arafa’s ‘Halim (Halim)’ (2006) portray, as the titles clearly suggest, two significant figures whose lives thoroughly intersected with Nasser’s - Nasser’s successor Anwar al-Sadat and the legendary singer Abdel Halim Hafiz. Expectedly, therefore, Nasser himself is abundantly referenced in those films, albeit differently. This paper seeks to examine the ways in which Egyptian filmmakers impersonate Nasser on the screen. Starting with scholarly definitions of the biopic, the paper will first ponder the reasons that have made the biopic an unattractive genre to Egyptian filmmakers. It will then argue that the popularity of Nasser and his wide appeal to the public has transformed the status of the biopic genre in Egyptian cinema. However, the impersonation of Nasser in the four films above proved a daunting mission to filmmakers. As this paper will show, unless he is the main character, the reenactment of Nasser in films will constantly pose dilemmas to filmmakers, a few of which will be discussed in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Zaki" title="Ahmad Zaki">Ahmad Zaki</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-pictures" title=" bio-pictures"> bio-pictures</a>, <a href="https://publications.waset.org/abstracts/search?q=Egyptian%20cinema" title=" Egyptian cinema"> Egyptian cinema</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasser" title=" Nasser"> Nasser</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasser%2056" title=" Nasser 56"> Nasser 56</a> </p> <a href="https://publications.waset.org/abstracts/38660/history-on-the-screen-nasser-and-the-biographical-film-in-egyptian-cinema" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38660.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">419</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> Students’ Views on Mathematics Learning: A Cross-Sectional Survey of Senior Secondary Schools Students in Katsina State of Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fahad%20Suleiman">Fahad Suleiman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this paper is to study students’ view on mathematics learning in Katsina State Senior Secondary Schools of Nigeria, such as their conceptions of mathematics, attitudes toward mathematics learning, etc. A questionnaire was administered to a random sample of 1,225 senior secondary two (SS II) students of Katsina State in Nigeria.

It attempts to organize socio-spatial relationships at exceptional ranges of governance Urban planning offers the social, monetary and environmental effects of defining spatial obstacles and the influence on the spatial distribution of resources. The dreams and methods of reaching such dissemination vary extensively traditionally and geographically and are often challenged through traditional strategies that expose the political nature of application interventions and the bounds of technical know-how claims. Space, network, argument, and postcolonial debates address how present-day socio-spatial organization is formed, what needs to or should not trade, and the way it underscores whether or not a good plan will contribute to a given situation. Inside the absence of an agreed-upon technical justification for the planning exercise, the planning idea has a tendency to focus on normative processes, positioning making plans as an area for participatory democracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20governance" title="environmental governance">environmental governance</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20planning" title=" environmental planning"> environmental planning</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20management" title=" environmental management"> environmental management</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20competitiveness" title=" sustainable competitiveness"> sustainable competitiveness</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/161809/governance-and-local-planning-for-sustainability-need-for-change-implications-of-legislation-on-local-planning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161809.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">122</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> Development of Variable Order Block Multistep Method for Solving Ordinary Differential Equations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Suleiman">Mohamed Suleiman</a>, <a href="https://publications.waset.org/abstracts/search?q=Zarina%20Bibi%20Ibrahim"> Zarina Bibi Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Nor%20Ain%20Azeany"> Nor Ain Azeany</a>, <a href="https://publications.waset.org/abstracts/search?q=Khairil%20Iskandar%20Othman"> Khairil Iskandar Othman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a class of variable order fully implicit multistep Block Backward Differentiation Formulas (VOBBDF) using uniform step size for the numerical solution of stiff ordinary differential equations (ODEs) is developed.

A survey was conducted to study the present tillage practices and determine the constraints associated with the use of animal traction for mechanized tillage of the Fadama. The study revealed that Fadama farmers (mostly aged between 36 and 60 years) use manual labour with tools like small hoe, big hoe and rake to till during the dry season (October of one year to March of the next year). Most of the Fadama farmers believe that tillage operations like ploughing, harrowing and basin making are very important tillage activities in the preparation of seedbeds for crops like green maize, sugarcane and vegetables, but are constrained to using animal traction for tillage due to beliefs like unsuitability of the workbulls and corresponding implements, Fadama soil being too heavy for the system and the non-attainment of deep tillage required by crops like sugarcane and potato. These were affirmed by local blacksmiths of animal traction implements and agricultural officers of government establishments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=snimal%20traction" title="snimal traction">snimal traction</a>, <a href="https://publications.waset.org/abstracts/search?q=Fadama" title=" Fadama"> Fadama</a>, <a href="https://publications.waset.org/abstracts/search?q=tillage%20implements" title=" tillage implements"> tillage implements</a>, <a href="https://publications.waset.org/abstracts/search?q=workbulls" title=" workbulls"> workbulls</a> </p> <a href="https://publications.waset.org/abstracts/16349/a-survey-of-the-constraints-associated-with-the-mechanized-tillage-of-the-fadama-using-animal-drawn-tillage-implements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16349.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">507</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> Social Networking Sites and Employee Engagement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sultan%20Ali%20Suleiman%20AlMazrouei">Sultan Ali Suleiman AlMazrouei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: The purpose of this paper is to examine the effect of communication through social networking sites (Facebook, Twitter) on employee engagement. Methodology: A quantitative survey was used to collect data from 440 employees from the Ministry of Education in Oman. SPSS software was used to analyze the data. Findings: The results revealed a positive significant relationship between communication via Facebook and employee engagement. However, communication via Twitter does not influence employee engagement significantly. Practical implications: Managers can benefit from the study by understanding the importance of communication via Facebook with employees in order to increase their engagement. They should post their views and thoughts on Facebook and encourage their employees to be members which would be reflected on their psychological side positively. That gives them a feeling of belonging to a network. Originality/value: The study enriches the human resources management literature by examining a theoretical framework about the influence of social networking sites usage on employee engagement. This is one of the few studies that focus on the relationship of social networking sites usage with employees' engagement. It is the first study in an Omani context. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=employee%20engagement" title="employee engagement">employee engagement</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20networking%20sites" title=" social networking sites"> social networking sites</a>, <a href="https://publications.waset.org/abstracts/search?q=Facebook" title=" Facebook"> Facebook</a>, <a href="https://publications.waset.org/abstracts/search?q=Twitter" title=" Twitter"> Twitter</a> </p> <a href="https://publications.waset.org/abstracts/34226/social-networking-sites-and-employee-engagement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34226.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">333</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> Evaluating the Suitability and Performance of Dynamic Modulus Predictive Models for North Dakota’s Asphalt Mixtures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Duncan%20Oteki">Duncan Oteki</a>, <a href="https://publications.waset.org/abstracts/search?q=Andebut%20Yeneneh"> Andebut Yeneneh</a>, <a href="https://publications.waset.org/abstracts/search?q=Daba%20Gedafa"> Daba Gedafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Suleiman"> Nabil Suleiman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Most agencies lack the equipment required to measure the dynamic modulus (|E*|) of asphalt mixtures, necessitating the need to use predictive models. This study compared measured |E*| values for nine North Dakota asphalt mixes using the original Witczak, modified Witczak, and Hirsch models. The influence of temperature on the |E*| models was investigated, and Pavement ME simulations were conducted using measured |E*| and predictions from the most accurate |E*| model. The results revealed that the original Witczak model yielded the lowest Se/Sy and highest R² values, indicating the lowest bias and highest accuracy, while the poorest overall performance was exhibited by the Hirsch model. Using predicted |E*| as inputs in the Pavement ME generated conservative distress predictions compared to using measured |E*|. The original Witczak model was recommended for predicting |E*| for low-reliability pavements in North Dakota. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asphalt%20mixture" title="asphalt mixture">asphalt mixture</a>, <a href="https://publications.waset.org/abstracts/search?q=binder" title=" binder"> binder</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20modulus" title=" dynamic modulus"> dynamic modulus</a>, <a href="https://publications.waset.org/abstracts/search?q=MEPDG" title=" MEPDG"> MEPDG</a>, <a href="https://publications.waset.org/abstracts/search?q=pavement%20ME" title=" pavement ME"> pavement ME</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=prediction" title=" prediction"> prediction</a> </p> <a href="https://publications.waset.org/abstracts/182251/evaluating-the-suitability-and-performance-of-dynamic-modulus-predictive-models-for-north-dakotas-asphalt-mixtures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182251.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">47</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> An Analysis of Organoleptic Qualities of a Three-Course Menu from Moringa Leaves in Mubi, Adamawa State Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rukaiya%20Suleiman%20Umar">Rukaiya Suleiman Umar</a>, <a href="https://publications.waset.org/abstracts/search?q=Annah%20Kwadu%20Medugu"> Annah Kwadu Medugu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <em>Moringa</em> <em>oleifera</em> is mainly used as herbal medicine in most homes in Northern Nigeria.

This paper evaluates the acceptability of dishes produced with fresh moringa leaves with a view to promoting it in popular restaurants. A three course menu consisting of cream of moringa soup as the starter, mixed meat moringa sauce with semovita as the main dish and moringa roll as sweet was produced and served to a 60-member taste panel made of three groups of 20 each. Respondents were asked to rate the organoleptic qualities of the samples on a 10-point bipolar scale ranging from 1 (Dislike extremely) – 10 (Like extremely). Data collected were treated to one sample t-test and One Way ANOVA. Results show that the panelists extremely like the moringa products.
