Assessing the Need for PhD in Information Studies: Stakeholder Insights  [PDF]
Sajjadur Rehman, Abdus Sattar Chaudhry, Hessah O. Alasousi
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105322
Abstract:
Seeking insights of stakeholders is an important element of the needs assessment process for starting a doctoral program. This paper reports a study that reviewed the perspectives of stakeholders with regard to a PhD in information studies. Feedback from major stakeholders was sought using a combination of qualitative and quantitative methods: a web-based survey of 180 relevant stakeholders (including current master students, alumni of the department, faculty members and working information professionals) followed by a focus group discussion with 7 faculty members from Kuwait University and Public Authority for Training and Education. Findings showed that there was a need for starting a PhD program in information studies at Kuwait University. Data also provided important insights about the structure of the proposed program, its content, areas of coursework and specializations. Results of the study might be useful for developing a PhD program in other universities. The findings are also expected to provide guidelines for conducting needs assessment for doctoral programs in information studies.
Is the immediate use of guided bone regeneration on exposed dental implant threads beneficial?  [PDF]
Anwar Ramadhan, Abdulaziz Ali, Hessah Aljiran, Kholoud Hasan, John Madda
Open Journal of Stomatology (OJST) , 2013, DOI: 10.4236/ojst.2013.38072
Abstract:

Thin buccal bone has a risk of thread exposure, and placement of a graft is the mainline of treatment for thread exposure. However, this process takes time as the patient is expected to wait for healing to occur before the implant can be placed. To overcome the waiting period, this study views a different method. This study examines the use of guided bone regeneration on the day of implant placement on buccal bone where thread exposure occurs. This process has the advantage of avoiding the patient to go through multiple operations till receiving the final prosthetic treatment, also saving time and money for both the patient and the practitioner.

International Journal of Chronic Diseases , 2014, DOI: 10.1155/2014/652341
Abstract: Obesity is a medical disease that is increasing significantly nowadays. Worldwide obesity prevalence doubled since 1980. Obese patients are at great risk for complications with physical and psychological burdens, thus affecting their quality of life. Obesity is well known to have higher risk for cardiovascular diseases, diabetes mellitus, musculoskeletal diseases and shorter life expectancy. In addition, obesity has a great impact on surgical diseases, and elective surgeries in comparison to general population. There is higher risk for wound infection, longer operative time, poorer outcome, and others. The higher the BMI (body mass index), the higher the risk for these complications. This literature review illustrates the prevalence of obesity as a diseases and complications of obesity in general as well as, in a surgical point of view, general surgery perioperative risks and complications among obese patients. It will review the evidence-based updates in these headlines. 1. Introduction Obesity is a medical disease that is increasing significantly nowadays. It is classically defined as a body mass index ≥30?kg/m2. Almost all healthcare professionals are exposed to obese patients because of their higher risk for morbidity and mortality, and surgeons are not exceptions [1]. Obesity and its severity can be measured by several methods [2]. They include the following.(a)Body mass index (BMI) [1]: this is the most common method to measure obesity in adults (see Table 1(a)) and children (see Table 1(b)).(b)Skin fold thickness [2] (biceps, triceps, subscapular, and suprailiac): it measures the subcutaneous fat to determine the percentage of body fat.(c)Waist circumference [2]: it is a common method to measure the risk of cardiometabolic affection (see Table 2).(d)Waist-to-hip ratio [2]: it examines fat distribution and it is used less frequently.(e)Waist-to-height ratio [3]: waist-to-height ratio is a better screening tool than waist circumference and BMI for adult cardiometabolic risk factors in both sexes (see Table 3). Table 1: (a) Adults and (b) children. Table 2 Table 3 2. Prevalence of Obesity 2.1. Worldwide Worldwide obesity prevalence doubled since 1980 [4]. In 2010, approximately 1.0 billion adults are overweight, and a further 475 million are obese [5]. It was also estimated in 2010 that up to 200 million school-aged children are either overweight or obese; of those, 40–50 million are classified as obese [5, 6]. 2.2. Regional (Saudi Arabia) In 2005, the estimated overall obesity prevalence in Saudi Arabia was 35.5% [7]. In 2010, Saudi Arabia was
Stress Loops Effect in Ductile Failure of Mild Steel  [PDF]
O.O. Oluwole
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2009, DOI: 10.4236/jmmce.2009.84026
Abstract: A simulation study of effect of stress on mild steel microstructure has revealed stress loops at areas of stress application which are believed to be the root cause of the ductile failure morphology (cup and cone) in ductile alloys under plane strain conditions. The areas of concentration of these stress loops were observed to be that of subsequent instability (or necking) observed in mild steel and other materials of low friction (flow) stress. Shear stress loops with angular bearing of 450 to the tensile axis were observed to instigate both the failure site and shear morphology in these materials. In plane stress conditions, shear was seen to be that of a wave shape running obliquely to area of stress application resulting in oblique necking observed in thin mild steel sheets.
Boundary Value Problem for an Operator-Differential Riccati Equation in the Hilbert Space on the Interval  [PDF]
O. O. Pokutnyi
Advances in Pure Mathematics (APM) , 2015, DOI: 10.4236/apm.2015.514081
Abstract: The paper is devoted to obtaining the necessary and sufficient conditions of the solvability of weakly perturbed boundary-value problems for the nonlinear operator-differential Riccati equation in the Hilbert space on the interval and whole line with parameter ?. We find the solution of the given boundary value problem which for ε = 0 turns in one of the solutions of generating boundary value problem. Solution of the generating problem is constructed with the using generalized operator in analytical form. Iterative process for finding of solutions of weakly nonlinear equation with quadratic error is constructed.
Vertex-transitive maps on a torus
O. Such
ACTA MATHEMATICA UNIVERSITATIS COMENIANAE , 2011,
Abstract: We examine FVT (free, vertex transitive) actions of wallpaper groups on semiregular tilings. By taking quotients by lattices we then obtain various families of FVT maps on a torus, and describe the presentations of groups acting on the torus. Altogether there are 29 families, 5 arising from the orientation preserving wallpaper groups and 2 from each of the remaining wallpaper groups. We prove that all vertex-transitive maps on torus admit an FVT map structure.

Classification of accidents and incidents makes principle of hieratic collateral subordination, which determines separate classification of direct and main reasons that enables to estimate weight destiny of every structure in the decline of safety flight and expose most bottleneck in the aviation system. Exposure of main reasons and frequency of their repetition, for a concrete period, allows to define the role of each components in the decline of safety of flights and estimate efficiency of the before developed prophylactic measures from warning of the same type aviation events and incidents in a future. Рассмотрены классификация авиационных происшествий и инцидентов, что позволяет оценить удельную долю каждой структуры в снижении безопасности полете. Выявлены основные причины и частоту повторяемости авиационных происшествий и инцидентов. Оценена эффективность ранее разработанных профилактических мероприятий по предупреждению однотипных авиационных происшествий и инцидентов в будущем.
