reliability of a system is the probability that it will function as intended for the required period of time. the opposite of reliability is failure probability per unit time or over time, such as a life cycle. following a review of existing reliability codes and approaches, comprehensive approaches to assess the reliability of offshore structures are described, including probabilistic analysis...

the risks of fire and explosion in oil and gas industry need to be managed. the objectives of the present study were to assess the risk of fire and explosion in iso-max unit of tehran oil refinery using dow’s fire and explosion index and to study the influences of the controlling methods. the latest version of dow fire and explosion index guideline was applied to calculate the fire and explosio...

MARK C. PAULK Software Engineering Institute he Capability Maturity Model T Model for Software, developed by the Software Engineering Institute, and the ISO 9000 series of standards, developed by the International Organization for Standardization, have the common concern of quality and process management. The two are driven by similar issues and are intuitively correlated, but they differ in th...

The dual-concentric-core photonic crystal fiber composed of pure silica and air is proposed in this paper. Around 1.55 μm, it exhibits a negative chromatic dispersion as high as –20000 ps/(km.nm). The finite element method with perfectly matched absorbing layers boundary condition is used to investigate the guiding properties. The explanations to propagation states of the fundamental mode and t...

INDIAN PEDIATRICS 83 VOLUME 43JANUARY 17, 2006 Day +7 at 5 mcg/kg/d. CsA was changed to the oral route on Day + 13. An absolute neutrophil count >500/mm3 was attained on day +9 and an unsupported platelet count >20000/mm3 was achieved on day +30. Chimerism analysis on day +24 by XY analysis revealed 100% donor cells. Patient was discharged on day +31. Patient is well at last follow up on day +140.

von Willebrand factor (VWF) is a large plasma glycoprotein that exists as a series of multimers of molecular weight 800-20000 kD. VWF has two main functions: as a carrier protein for coagulation factor VIII and as an adhesive protein involved in vessel wall-platelet interaction. Its function as an adhesive protein is most important in situations of high shear stress. Inherited defects in VWF ma...

It has been estimated that approximately 15000 to 20000 hours are required to train a surgeon.1 However, several time-constrains imposed globally2 have significantly reduced training time in the Operating Room (OR) posing a significant challenge for surgical educators and creating an impetus for the development of new educational methods.3 Since August 2005, all medical graduates in the United ...
