Crashworthiness capability of jute and glass fibre reinforced epoxy tubes under quasi-static loading condition for automotive application

During last few years, the interest in using natural fibers as reinforcement in polymers has increased dramatically. Natural fibers are not only strong and lightweight but also relatively very cheap. This study examined the potential utilization of jute in the crash energy absorption. A combination of hand layup and vacuum bladder technique was kused to search the influence of utilizing jute fibre on crashworthiness parameters of composite materials. To improve the mechanical properties, jute fiber was hybridized with glass fiber. In this work, there are two main parts of study. Firstly, it is to investigate the effect of cross-sectional shapes, number of layers and temperature treatment on the progressive deformation of jute/epoxy composite tubes. Secondly, the suitable type of geometry was chosen to study the effect of hybrid (jute-glass/epoxy) onto the structural designs. All the tests were undergone quasi-static axial crushing of 10 mm/min. Their peak load (Pmax), mean load (Pm), energy absorption (EA) and specific energy absorption (SEA) were discussed in detail. In the study of types of five geometrical shapes (corrugated, circular, hexagonal, octagonal and decagonal cross sectional) with different number of layers (two, three and four layers). It is found that the corrugated geometric shape with three layers (RHS) gives the best energy absorption (30.92 J/g) in specific energy absorption parameter compared to other geometries used in present study. For the temperature treatment, the results showed that the post-curing by gradual temperature treatment (TT) improved the peak load by decreased with 55% as compared to similar circular specimen without temperature treatment (No TT). From the test, it is found that the substitution of one layer of jute fibre with one layer of glass fibre resulted in an improvement in the crashworthiness parameters than layers jute. The best result was obtained when hybrid jute-glass was used, where the energy absorption and specific energy absorption was improved by about 43% and 31%, respectively

Factors Affecting UAE Consumers’ Attitudes Towards Using Social Networking Sites in Hotel Selection

This study focuses on the influence of social networking sites on travelers' attitudes towards hotel selection in the UAE. A social networking site (SNS) is a form of social media that provides a platform for people to connect with each other. It is very important to examine how individual travelers are utilizing SNS when they select a hotel. Therefore, the objective of this study is to investigate if Perceived Ease of Use (PEU), Perceived Usefulness (PU), and Perceived Risk (PR) have any influence on attitude toward using social media (ATUSM). The study will use an exploratory research design which employs quantitative data. Convenience sampling technique was used to distribute the self-administered survey questionnaires on different hotels in the UAE. As hypothesized, the results show the positive effect of Perceived Ease of Use (PEU), Perceived Usefulness (PU), and Perceived Risk (PR) on consumers' attitude toward using social media (ATUSM) in hotel selection. Keywords: social networking sites, attitude, perceived ease of use, perceived usefulness, perceived risk, hotel selection DOI: 10.7176/JMCR/66-03 Publication date:March 31st 202

An activity prediction model using shape-based descriptor method

Similarity searching, the activity of an unknown compound (target) is predicted through the comparison of an unknown compound with a set of known activities of compounds. The known activities of the most similar compounds are assigned to the unknown compound. Different machine learning methods and Multilevel Neighborhoods of Atoms (MNA) structure descriptors have been applied for the activities prediction. In this paper, we introduced a new activity prediction model with Shape-Based Descriptor Method (SBDM). Experimental results show that SBDM-MNA provides a useful method of using the prior knowledge of target class information (active and inactive compounds) of predicting the activity of orphan compounds. To validate our method, we have applied the SBDM-MNA to different established data sets from literature and compare its performance with the classical MNA descriptor for activity prediction

Lessons Tanzanian Elites and Policy Makers Can Learn From East Asian Tigers on the Idea of Developmental States

Abstract: Over the past fifty years in developing world, the role of the state intervention in promoting economic growth and social progress has been a subject of disputing among political elites, international development experts and policy analysts. Recognition of the economic growth success of East Asia has led to new thinking on what developmental states idea should be accomplished. The observable optimism performance of East Asian Tigers on the contextual of developmental states is keen in the fact that economic growth can be achievable when states commitment is concerned with respect to capitalist based economy. Since Tanzania is in a unique position of possessing some resources in which other East Asian Tigers did not posses thou their commitment and high standard of responsibility were imperative to their success. It is in this line therefore this paper attempts to draw attentions of Tanzanian Elites and Policy makers on how they can learn from the story of development states in East Asia so as to invent it into the development agenda in building sustainable development for the people of Tanzania

Estimation of genetic diversity between three Saudi sheep breeds using DNA markers

The genetic variation of Najdi, Harri and Awassi breeds of Saudi sheep prevailing in Raniah province of Makka district were assessed and compared to Sudanese Desert sheep using random amplified polymorphic DNA polymerase cahin reaction (RAPD-PCR) technique. Five primers successfully amplified distinguishable 40  bands with an average of 96% polymorphism revealing that Saudi sheep breeds possess the needed genetic variation required for further genetic improvement. The resulted dendrogram showed that, there are two main separate clades. The Desert sheep is genetically distant and appeared as out-group from the Saudi sheep breeds. The first main clade included all of the Najdi individuals and only two individuals from Harri breed. While, the second main clade comprised two subgroups, the first one included individuals from Harri breed and the second included both Harri and Awassi individuals. The cluster analysis shows that Najdi breed is  genetically different from both Harri and Awassi and that some Harri individuals showed genetic closeness to Awassi. The present study will help to clarify the image of the genetic diversity of these local Saudi sheep breeds in Raniah province and should be followed by further studies using advanced DNA markers and all  available breeds in the kingdom to get the precise estimation of the phylogeny of these local genetic resources.Key words: Dendrogram, biodiversity, Sudanese sheep, random amplified polymorphic DNA (RAPD), Saudi sheep

The Influence of Rewards for Creativity on Employee Creativity Performance

Abstract: Many scholars and practitioners are concerned with understanding how and when to motivate individuals to be more creative. We argue that the conflicting ideas may be due to differences between findings towards reward conditions and the situation in which rewards has to be offered. Hence, it is vital to portray in this study that motivating employees to be creative is important for many firms. Amount of literature shows that employee performance can be encouraged by extrinsic and intrinsic rewards in their everyday tasks. This paper, therefore, investigates these kinds of rewards and shows its effectiveness in attracting creative performance. It concluded by arguing that, human behaviors are stimulated by extrinsic motivations attained from works, which are capable to fulfill innate parts of individuals. Similarly, a person is intrinsically motivated when he or she found that the work is able to fulfill his or her psychological needs for the significant experience

The present study was conducted to find out the water requirements and most suitable irrigation frequencies for cowpea (Vigna unguiculata L.) var grown under drip irrigation. The treatments were based on the IW:CPE ratio at different empirical pan factors 0.6 , 0.8, 1.0, 1.,1.4 , and 1.6 Ef (where Ef = IW/CPE). It was observed that the irrigation interval was variable values decreased by increasing Ef value and with the progress of the growing season. The 1.2 and 1.0 IW: CPE treatments with approximately 4 days irrigation interval were achieved the best results. The total amount of applied water during Cowpea growing season was varied between 247.7 and 266.5mm with 254.8mm as a mean. Irrigation treatment with Ef1.2 was superior over the rest of other treatments in fresh seed yield (5.13 ton.hec.-1), crop water productivity (2.14 kg.m-3), biological yield (6.88 ton.hec.-1) , fresh pod yield (7.33 ton.hec.-1), weight of 100 seed (31.28gm), number of seed/pod (9.34) and netting percentage (37.1). The lowest values of the most parameters used in this study were obtained by Ef 0.6 irrigation treatment. &nbsp

The impact of design thinking on the learning of basketball and badminton

This study investigated the impact of the design thinking strategy on students' acquisition, learning, and maintenance of basketball and badminton skills. Using an experimental method, researchers compared two groups: an experimental group (Group A) that utilized the design thinking strategy and a control group (Group C) that used traditional teaching. The sample consisted of 58 third-year students from the Faculty of Physical Education and Sports Sciences at Al-Mustaqbal University, representing both groups. The acquisition test, prepared by the researchers, covered comprehension, interpretation, and application of concepts. It followed the same lesson sequence as the control group. Pre-existing basketball and badminton skills tests from the Hilla College curriculum were used. Statistically significant differences were found between the experimental and control groups, with the experimental group outperforming the control group in both the acquisition (p < 0.05) and maintenance tests (p < 0.05). The design thinking strategy effectively enhances the acquisition and maintenance of basketball and badminton skills compared to traditional methods. It also increases student engagement by fostering active participation, discussions, and creative problem-solving
