Measurements of metabolic energy consumption and free-walking velocity were recorded for four persons with trans-femoral amputation with variations of prosthesis mass and mass distribution. Hot-film anemometers, rate gyroscopes, and a force platform were used to measure prosthetic limb segment velocities and ground reaction forces. Metabolic energy consumption for the nine configurations of mas...

Nuts and seeds are rich in unsaturated fat and other nutrients that may reduce inflammation. Frequent nut consumption is associated with lower risk of cardiovascular disease and type 2 diabetes. The authors examined associations between nut and seed consumption and C-reactive protein, interleukin-6, and fibrinogen in the Multi-Ethnic Study of Atherosclerosis. This 2000 cross-sectional analysis ...

Oxygen consumption of the Red Sea coral reef sponge Negombata magnifica was measured using both incubation and steady-state methods. The latter method was found to be the more reliable because sponge activity remained stable over time. Oxygen consumption rate was measured during three levels of sponge activity: full activity, reduced activity and basal activity (starved). It was found that the ...

Potential risk factors for snoring were studied in a population of 457 middle-aged men. Eversnoring was reported by 60% of the men and snoring with an age of onset before or equal to 20 years by 13%. Eversnoring was significantly related to older age, higher body mass index and smoking habits. Alcohol consumption, estimated by questionnaire and gamma-glutamyl transpeptidase was unrelated to a h...

Plasma levels of total high density lipoprotein cholesterol (HDL) and its subfractions (HDL2 and HDL3) were measured in 366 healthy Caucasian males; these values were related to a number of coronary risk factors. On univariate statistical analysis, total HDL was negatively correlated with cigarette consumption, body mass index, and serum triglycerides, and positively associated with level of ph...

a suitable diet and oviposition substrate are two basic needs for successful mass rearing of orius spp. and this may reduce their production costs. the effect of various foods containing eggs of ephestia kuehniella and sitotroga cerealella with various pollens were investigated on the biological parameters of o. albidipennis in the laboratory. moreover, survival, hatching rate and fecundity of ...

the purposes of this article are studying the effects of oxygen presence on waste wood pyrolysis process in order to produce bio-char. to reach the goal, cubic samples of size 2.5 cm pyrolized at 300 and 400 °c. the surface and center temperatures of samples were measured and their mass losses were calculated from the ratio of pyrolized mass to initial mass of the sample. increase in temperatur...
