OBJECTIVE To assess the pattern of use and impact of patient sitters on the quality of healthcare in Taif Armed Forces Hospital, Taif, Kingdom of Saudi Arabia (KSA). METHODS A cross-sectional survey was conducted at the Armed Forces Hospital, Taif Region, KSA from 1st January to 30th March 2008. The study included 203 admitted patients, 125 patient sitters, and 213 physicians and nurses. Thre...

Phosphorelays are extended two-component signalling systems found in diverse bacteria, lower eukaryotes and plants. Only few of these systems are characterized, and we still lack a full understanding of their signalling abilities. Here, we aim to achieve a global understanding of phosphorelay signalling and its dynamical properties. We develop a generic model, allowing us to systematically anal...

Structural Estimates of the Intergenerational Education Correlation Using a structural dynamic programming model, we investigate the relative importance of family background variables and individual specific abilities in explaining cross-sectional differences in schooling attainments and wages. Given scholastic ability, household background variables (especially parents' education) account for ...

OBJECTIVE To evaluate whether physical disability reaches a plateau in the oldest age groups. DESIGN Cross-sectional survey. PARTICIPANTS A total of 3351 individuals, which included all those living in Denmark who celebrated their 100th anniversary during the period from 1 April 1995 to 31 May 1996 (276 subjects) and all Danish twins aged 75-94 registered in the Danish Twin Register (3075 s...

This study is part of a programmatic research effort into the determinants of self-assessed abilities. It examined cross-cultural differences in beliefs about intelligence and self- and other-estimated intelligence in two countries at extreme ends of the European continent. In all, 172 British and 272 Turkish students completed a three-part questionnaire where they estimated their parents', par...

This paper discusses an approach to generate test data for path coverage based testing using Genetic Algorithms, Differential Evolution and Artificial Bee Colony optimization algorithms. Control flow graph and cyclomatic complexity of the example program has been used to find out the number of feasible paths present in the program and it is compared with the actual no of paths covered by the ev...

In the present work, the performance of the particle swarm optimization and the genetic algorithm compared as a typical geometry design problem. The design maximizes the heat transfer rate from a given fin volume. The analysis presumes that a linear temperature distribution along the fin. The fin profile generated using the B-spline curves and controlled by the change of control point coordinat...

In this paper, turbojet engine in ideal condition will be optimized by multi target genetic algorithm. The target functions are specific thrust (ST), specific fuel consumption (SFC) and thermal efficiency (ηt) that once will simultaneously be optimized by two by two way and the results will be revealed in the Pareto curves. For the second time these three objective functions will be optimized a...
