This research presents temperature distribution and thermal strain of functionally graded material cylinders with varying thickness and temperature-dependency properties that are subjected to heat fluxes in their inner and outer layers. The heterogeneous distribution of properties is modeled as a power function. Using first-order temperature theory and the energy method, governing equations are...
Type II diabetes mellitus is associated with congestive heart failure with preserved ejection fraction. This group of patients has been assumed to have isolated diastolic dysfunction; however, the longitudinal systolic contraction of the left ventricle has not been studied previously. The objective of the present study was to investigate the longitudinal contraction of the left ventricle in nor...
objective(s): several beneficial effects have been attributed to the probiotic lactic acid bacteria. it was determined that lactobacilli can exert antiproliferative effects on the various cancer cell lines including colon cancer. effects of lactic acid bacteria on colon cancer may vary from strain to strain and there is a need to find the new probiotic strains with tumor suppressing properties ...
Background and aims: Workload can be defined as the operator's required capacity to meet a special level of performance while performing a task. Optimized workload is a point at which any increase or decrease could have negative effects on operator's performance. Therefore, the aim of this study was to assess the workload using subjective and objective methodologies in the assembly lines of a c...
A cold strain index (CSI) based on core (Tcore) and mean skin temperatures (T sk) and capable of indicating cold strain in real time and analyzing existing databases has been developed. This index rates cold strain on a universal scale of 0-10 and is as follows: CSI = 6.67(Tcoret - Tcore 0) ⋅ (35 - Tcore 0)-1 + 3.33(T sk t -T sk 0) ⋅ (20 -T sk 0)-1, where Tcore 0 andT sk 0are initial measuremen...
BACKGROUND Environmental health research employs a variety of metrics to measure heat exposure, both to directly study the health effects of outdoor temperature and to control for temperature in studies of other environmental exposures, including air pollution. To measure heat exposure, environmental health studies often use heat index, which incorporates both air temperature and moisture. Howe...
Within the wr-orbital axis vector theory, the total rehybridization required for closure of the fullerenes is approximately conserved. This result allows the development of a structure-based index of strain in the fullerenes, and it is estimated that about 80 percent of the heat of formation of the carbon atoms in C60 may be attributed to a combination of v strain and steric inhibition of reson...
Individuals living in hot climates face health risks from hyperthermia due to excessive heat. Heat strain is influenced by weather exposure and by individual characteristics such as age, sex, body size, and occupation. To explore the population-level drivers of heat strain, we developed a simulation model that scales up individual risks of heat storage (estimated using Myrup and Morgan's man mo...

Physiol. 277 (Regulatory Integrative Comp. Physiol. 46): R556–R564, 1999.—A cold strain index (CSI) based on core (Tcore) and mean skin temperatures (Tsk) and capable of indicating cold strain in real time and an...
