BACKGROUND Cancellation of operations in hospitals is a significant problem with far reaching consequences. This study was planned to evaluate reasons for cancellation of elective surgical operation on the day of surgery in Ayub Teaching Hospital, Abbottabad. METHODS From July 2006 to June 2007 the medical records of all the patients who had their(More)
Financial risk associated with over or underproduction of electricity is studied. A two-stage stochastic model that considers parameter uncertainties is developed. The model was applied to a real case to meet projected electricity demand of a fleet of generating stations. Incorporation of financial risk resulted in an increase in electricity cost. The(More)
BACKGROUND How psychiatrists introduce themselves in the first consultation may influence the therapeutic relationship. There is no evidence about what type of introduction patients prefer. AIMS To assess experimentally patients' preferences for how psychiatrists introduce themselves. METHOD Twelve psychiatrists were filmed, each with three different(More)

OBJECTIVES Currently available vacuum devices used to assist women undergoing complicated labour are unsuitable for use in low-resource settings. The objective of this study was to evaluate the safety and feasibility of a new low-cost vacuum device, named Koohi Goth Vacuum Delivery System (KGVDS), designed for use in low-resource settings. METHODS A(More)
Keywords: Berry phase Density functional theory Linearized augmented plane wave Polarization Effective charge a b s t r a c t We present a module that enables computation of polarization using density functional theory based on the full potential linearized augmented plane wave package WIEN2k. The theoretical background of deriving microscopic polarization(More)
A low coercivity and, consequently, low hysteresis loss are desired properties for ferroelectric materials used in high-power and high-frequency actuators. The coercive field required for the onset of ferroelectric switching is shown to develop a strong directional anisotropy due to peculiarities of an energy surface associated with the polarization(More)
BACKGROUND Uptake of family planning services in Pakistan has remained slow over the past decade despite a rapid increase in availability and awareness, indicating that social barriers may be preventing uptake. Social barriers such as opposition by family members have largely been studied qualitatively; there is a lack of quantitative evidence about the(More)
