background depression and sleep disorders are more prevalent among rotational shift workers than regular day workers. people with sleep disorders have higher inflammatory and pre-inflammatory cytokines than those in the control group. objectives the present study was conducted to investigate serum level of high sensitivity c-reactive protein (hscrp), interleukin-6 (il-6) and cortisol among depr...

In this article, turbulent flow heat transfer in the air gap between rotor and stator of a generator under nonhomogeneous heat flux is studied experimentally. The rotor consists of four symmetrical triangular grooves. The stator surface is smooth and does not include any grooves. The relative heat flux between the rotor and the stator is 1 to 3. Temperature and heat flux are measured locally at...

in this work, improved heat generation models are developed for straight and tapered shoulder geometries with different tool pin profiles in friction stir welding. the models are developed considering the welding process as a combination of the pure sliding and the pure sticking conditions. from the results, the amount of heat generation is directly proportional to the number of edges in the pi...

Shift work can be attributed to some of social and health problems in working community. In this study an attempt was made to study the sleep and wakefulness patterns in nurses engaged in rotational and non-rotational shift work in a hospital through sleep charts. It was observed that non-rotational workers enjoyed more frequent and longer naps and had less disturbances in their sleep patterns ...

According to the wide application of segmental lining in mechanized tunneling, recognizing the behavior of segmental lining joints is important in tunnels designing. In the structural analysis of the tunnel segmental lining, segmental joints can be considered as elastic joints, and their stiffness characteristics are affected by the rotational, shear, and axial stiffness. The purpose of this wo...
