Qatar University is a public university in Qatar, located on the northern outskirts of the capital Doha. As of 2014, there are over 16,000 students. Courses are taught in Arabic or English . The university is the only government university in the country. The university hosts seven colleges – Arts and science, Business and Economics, Education, Engineering, Law, Sharia and Islamic Studies, and a College of Pharmacy – with a total of almost 8000 students at a 13:1 student-teacher ratio.Students entering the university are placed in a “Foundation Program”, which ensures the acquirement of skills such as math, English, and computer technology.Many of its academic departments have received or are currently under evaluation for accreditation from leading organizations. In addition to undergraduate academics, QU has a research infrastructure including research labs, an ocean vessel, technical equipment and a library housing thousands of books, including a collection of rare manuscripts.The university serves on behalf of the government and private industry to conduct regional research, particularly in areas of the environment and energy technologies. Qatar University has a student body of fifty-two nationalities, 65% of which are Qatari nationals. About 35% are children of expats. Women make up approximately 70% of the student population, and are provided their own set of facilities and classrooms. QU has an alumni body of over 30,000 graduates. Wikipedia.

Torsional ring shear tests were performed on composite specimens that simulate the field alignment of municipal solid waste (MSW) landfill liner and cover system components. Simultaneous shearing was provided to each test specimen without forcing failure to occur through a pre-determined plane. Composite liner specimens consisted of a textured geomembrane (GM) underlain by a needle-punched geosynthetic clay liner (GCL) which in turn underlain by a compacted silty clay. Hydrated specimens were sheared at eleven different normal stress levels. Test results revealed that shear strength of the composite liner system can be controlled by different failure modes depending on the magnitude of normal stress and the comparative values of the GCL interface and internal shear strength. Failure following these modes may result in a bilinear or trilinear peak strength envelope and a corresponding stepped residual strength envelope. Composite cover specimens that comprised textured GM placed on unreinforced smooth GM-backed GCL resting on compacted sand were sheared at five different GCL hydration conditions and a normal stress that is usually imposed on MSW landfill cover geosynthetic components. Test results showed that increasing the GCL hydration moves the shearing plane from the GCL smooth GM backing/sand interface to that of the textured GM/hydrated bentonite. Effects of these interactive shear strength behaviors of composite liner and cover system components on the possibility of developing progressive failure in landfill slopes were discussed. Recommendations for designing landfill geosynthetic-lined slopes were subsequently given. Three-dimensional stability analysis of well-documented case history of failed composite system slope was presented to support the introduced results and recommendations. © 2010 Elsevier Ltd.

Microbiologically Influenced Corrosion (MIC) is an electrochemical corrosion influenced by the presence/action of biological agents such as, but not limited to, bacteria. One of the key elements of MIC is sulphate-reducing bacteria (SRB). There are still many misunderstandings about these bacteria, their role in the deterioration of engineering materials and their importance over other types of corrosion-related micro-/macro-organisms. SRB do not require oxygen, yet they can be found in oxygenated environments; they are capable of tolerating a relative wide range of temperature, pH, chloride concentration and pressure values. Not only can SRB have deteriorating impact on engineering materials, they are also capable of inducing harm to health and agriculture. In this paper, after reviewing facts and figures regarding ecological and economical impacts of corrosion in general and MIC, in particular, the central concept of MIC, that is, biofilm formation and its deterioration mechanisms and the role of SRB in such mechanisms are described. Also, the possible enhancing role of SRB on stress corrosion cracking of steels and the controversial concept of no relationship between the number of SRB and corrosion rate are addressed and reviewed. © 2011 Springer-Verlag.

This paper reports on a case study conducted at a Japanese national university. Nine participants used the video recording feature on their cell phones to produce weekly video productions. The task required that participants produce one 30-second video on a teacher-selected topic. Observations revealed the process of video creation with a cell phone. The weekly video performances indicated that students were able to increase the number of words they spoke in one monologue. The surveys indicated that participants believed that using the cell phone video recording feature was a useful activity. However, they did not believe that such a task was transferable to other courses. The discussion emphasizes that, due to technological advances, educators need to understand the benefits and challenges of integrating cell phone devices as learning tools in their classrooms. In addition, whereas in the past researchers focused on reading and writing skills, this article reveals that it is now possible to use the video recording feature to evaluate learners' speaking skills. © 2011 Elsevier Ltd.

The purpose of this study was to investigate the effects of e-books on enhancing Jordanian preschool children's emergent literacy skills (experimental group), in comparison to children who were exposed to regular printed books (control group). To achieve the objectives of this study, the total of 92 children were assigned to either experimental group (n = 48) and control group (n = 44). The pre- and post-test data was collected on print awareness, vocabulary, alphabetic knowledge and phonological awareness skills to determine the effectiveness of e-books. The results indicated that children in experimental group performed significantly better than the children in control group. Moreover, significant differences were found according to gender, as the female children exhibited superior emergent literacy skills to the male children. Regarding the different emergent literacy skills, children in the experimental group achieved better improvement in the areas of print awareness and vocabulary. Based on these findings, it is recommended that pre-school institutions incorporate e-books activities into their classrooms. © 2014 Elsevier Ltd. All rights reserved.

Integral to the discipline of anthropology are both science and holism. The application of Optimality Theory to two partial kin terminologies narrows analysis to descriptive value, fragments phenomena, and constrains data selection, which precludes significant knowledge. Embedded in this critique is a call to move analysis from fragment to whole and from descriptive features to deeper levels of knowledge underlying kin terms, thereby leading to a cognitive path for holistic understanding of human phenomena. © 2010 Cambridge University Press.
