The present study analyzes the effect of work stressors, personal strain and coping resources on burnout among Chinese medical professionals. A total of 2,721 medical professionals were selected using the stratified cluster sampling method. A Chinese version of the Maslach Burnout Inventory-General Survey was used to measure burnout, whereas the Occupation Stress Inventory-Revised Edition was u...

It is well documented that there is clear relationship between the rate of drug me tabolism by liver microsomes and the intensity of the effect and toxicity of a variety of drugs (1-5). Recent studies indicated that the individual, strain, sex and species dif ferences in the rate of drug metabolism appear to be factors responsible for the individual, strain, sex and species differences in the e...

In the presented work, a non linear effect of rubber referred as Fletcher-Gent effect or Payne effect is investigated. It leads to a change in the rubber dynamic modulus with vibration amplitudes and, consequently, modifies resonance frequencies of mechanical systems including non linear elastomers. In this study a new methodology is developed to take into account Payne effect in a linear visco...

The present study investigated the effect of sumac (SWE) and Rosemary water extracts (RWE) on microbial growth in ground beef meat during refrigerated storage. The meat samples were explored for changes in TVC, E.coli (0157:H7) and S.aureus populations. Antimicrobial effectiveness of extracts was more pronounced against Gram-positive strain compared with Gram-negative strain. Antimicrobial impa...

A size-dependent Euler–Bernoulli beam model, which accounts for nonlocal stress field, strain gradient field and higher order inertia force field, is derived based on the nonlocal strain gradient theory considering velocity gradient effect. The governing equations and boundary conditions are derived both in dimensional and dimensionless form by employed the Hamilton principle. The analytical so...

Blood vessels are subjected to numerous biomechanical forces that work harmoniously but, when unbalanced because of vascular smooth muscle cell (vSMC) dysfunction, can trigger a wide range of ailments such as cerebrovascular, peripheral artery, and coronary artery diseases. Human pluripotent stem cells (hPSCs) serve as useful therapeutic tools that may help provide insight on the effect that su...

BACKGROUND Mechanical strain alters protein expression. It results in phosphorylation of MAP kinases and up-regulation of extracellular matrix proteins. We investigated whether phosphorylation of MAP kinase family members was increased in response to mechanical strain in fibroblasts from asthmatic patients (AF) and normal controls (NF), and whether phosphorylation of these signaling molecules w...

In this paper, the solution of a moving Volterra-type screw dislocation in an orthotropic layer, bonded between two piezoelectric layers is obtained using complex Fourier transform. The dislocation solution is then employed as strain nuclei to derive singular integral equations for a medium weakened by multiple moving cracks. These equations, which are classified as, Cauchy singular equations, ...
