The density and viscosity of carbonated aqueous 35wt% methyldiethanolamine solution were experimentally measured accompanied with the solubility of CO2 at temperatures from (303.15 to 363.15) K and pressures up to 0.8 MPa using the new setup developed in our laboratory.It was observed that both density and viscosity of mixtures decrease by increasing temperature and incr...
various human pressures are affecting the aquatic biocoenosis in running waters of iran - similar to many other areas of the world. overall 190 sites, 88 at salmonid (44 reference/impacted respectively) and 102 at cyprinid (50 reference/52 impacted) streams of the southern caspian sea basin were investigated in terms of human pressures present and the related impact on fish assemblages. in tota...
nonspecific activity-related arm pain is characterized by an absence of objective physical findings and symptoms that do not correspond with objective pathophysiology. arm pain without strict diagnosis is often related to activity, work-related activity in particular, and is often seen in patients with physically demanding work. psychological factors such as catastrophic thinking, symptoms of d...
investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
OBJECTIVE To study cardiovascular behavior and safety regarding a low-intensity exercise program for heart transplant candidates with severe heart failure. METHODS Twenty-one patients with severe heart failure on the transplant list of the UNIFESP university hospital (Brazil) were studied. Following evaluation, the patients were monitored during an exercise program with six progressive phases...
E-commerce and Human Resource Management: Theoretical Approaches and Issues for the Banking Industry
Electronic commerce technologies are changing the way that work tasks are conducted and thus has significant implications for the way organisations manage their human resource functions. Although the impact of IT on work and employment has been the subject of research, little attention has been paid to electronic commerce and its effect on work organisation and HR management. This paper examine...
Background Work-family conflict is a kind of role conflict created by incompatible pressures from family and work roles. Objective This study aimed to determine work-family conflict between medical and non-medical staffs in hospitals affiliated to Tehran University of Medical Sciences. Methods This research was a descriptive-analytical study with a cross-sectional design conducted during 201...
Individual differences are increasingly considered important in the relationship between work-family balance and health. The present study examined the role of autonomy-connectedness in positive and negative work-family interaction and family-work interaction. We also investigated the relationship of work-family interaction and family-work interaction with positive and negative affect, coping p...
In this study, a generalized equation is presented to calculate vapor pressure of pure substances as a function of reduced temperature, critical pressure, and acentric factor. With the presented model, vapor pressures have been calculated and evaluated with NIST data bank for 70 pure substances for about 14000 data points, and the overall average absolute percentage deviation has been only 0.78...
