research has shown that shift work, in particular night work, can have negative effects on the health, safety and well-being of workers. our study assessed, in a hospital setting, the effects of bright light (bl) on general health and psychological problems during night shift work. in an experimental design, 15 female nurses at a general hospital that located in tehran were exposed to moderate ...

How much of our self is defined by our work? Fundamental changes in the social organization of work are destabilizing the relationship between work and the self. As a result, parts of the self traditionally considered outside the domain of work—that is, nonwork identities—are increasingly affected by organizations and occupations. Based on an interdisciplinary review of literature on identity a...

oday’s challenging economic environment leaves little room for businesses in any industry to expend resources that promise little or no return. The health care industry, and Catholic health care in particular, share this challenge. In the midst of these pressures, something appears to be happening within the Catholic health care community, something that speaks to the unique understanding we br...

Prediction of available vapor pressure data in the case of compounds containing C-H-O led to derivations and recommendations of standard equations for this property. The accuracy of vapor pressure estimations is essential to use as a basis to calculate acentric factor, thermal and equilibrium properties. In this study, according to the previous work, an accurate equation to estimate vapor press...

Alkanolamine solutions such as 2-amino-2-methyl-1-propanol (AMP) are widely used in chemical industries for the removal of acid gases such as CO2 and H2S. In this work, the density of CO2, AMP, water, and AMP solutions using the Goharshadi–Morsali–Abbaspour Equation of State “GMA EoS” in the extended 50-degree range of temperatures (313.06-362.65 K) and pressures (0.5-40 MPa) was calculated. Th...

In this work, we consider each normal alkane as a hypothetical mixtureof methyland methylene groups, in which the interaction potential of each pair is assumed to be the average effective pair potential. Then, the LIR equation of state (EOS) is extended for such a hypothetical mixture. Also, three basic compounds, namely, propane, n-butane and cyclohexane, are used to obtain the contributio...

The production of helium 2 1S singlet metastable atoms has been investigated using a hollow cathode discharge and a Penning discharge, under dc discharge conditions. The density of metastable atoms was measured by atomic absorption using the 2 1S–3 1P transition (501.57 nm). A range of plasma currents, varying from 16 to 180 mA, and a range of pressures, from 100 mTorr to 5 Torr, were investiga...

like other valuable consideration marriage contracts are permissible provided the acceptability of any particular problem, but the marriage contracts, and have initiated some work on it should be welcoming as it is. including conditions in the marriage if there is no sex.some respected researchers in the licensing documents such condition as not warrant deference to be, were considered. to prov...

Recently there has been a wide debate on the role of so-called noncognitive skills, misnomer for personal skills needed to cope positively with personal, social and professional life. In this contribution an attempt is made clarify their meaning, prospect development possible evaluation. Reference in framework mainly world work, which they are more specifically referred as soft skills.

Recently, pervaporation separation processes have gained much attention in the separation of azeotropic and close boiling point organic-organic mixtures due to its high separation efficiency, economy, safety, and energy saving potentials. In this work, the effects of experimental factors such as feed composition and operating temperature on the performance of a commercial poly vinyl alcohol mem...
