INTRODUCTION Studies indicate that different areas of mental, physical, social and daily life functioning need to be considered in order to improve intervention outcomes in substance user patients. The aim of the study was to assess health-related quality of life (HRQOL) in patients diagnosed with opioid dependence as compared to healthy controls and patients diagnosed with depression and schiz...

In this chapter we will present a derivation of a mathematical model describing how cavitation influences the pressure distribution in a thin lubricant film between two moving surfaces. The main idea in the derivation is to first describe the influence of cavitation on the mass flow and thereafter using a conservation law for the mass. This leads to a nonlinear system with two complementary var...

In this study, the elastohydrodynamic lubrication (EHL) behaviour of high-speed spur gear contacts is investigated under dynamic conditions. A non-linear time-varying vibratory model of spur gear pairs is introduced to predict the instantaneous tooth forces under dynamic conditions within both the linear and non-linear operating regimes. In this model, the periodically time-varying gear mesh st...

In the conventional continuous casting of steel, either mold powder or oil can be added to lubricate the mold from sticking to the solidifying steel shell. The mold powder melts to form a molten slag or flux layer, and also acts to protect the molten steel from oxidation, to insulate the molten steel from heat loss, to absorb inclusions from the molten steel, to regulate heat transfer to mold w...

This study aimed to identify the mental health quality of life among patients with multiple sclerosis in Jordan. Thus, a descriptive quantitative design was used on total (N=100) Multiple Sclerosis that were randomly selected by using convenience sampling from Health Insurance Center capital Amman, Outcome measurement tools demographic data form and Quality Life-54 (MSQOL-54) Scale. The consist...
