... a fairly high buffer capacity, which is determined by the amount of H + or OH - ions that is needed until the pH value of a solution changes by the unit 1. Buffers contain a weak or medium strong acid (base) and the corresponding salt. Buffers that show a pK a in the range of the Stratum corneum surface...

... investigated regarding phase relation of the emulsion, absolute pH value and buffer capacity. The results show that only 23 preparations have an appropriate pH of ≤5.5 and only 3 preparations show a buffer capacity of ≥1.0. This outcome demonstrates the fact that the significance of pH and buffer capacity...

... performance capacity. In the 76th Nestlé Nutrition Institute Workshop, a group of expert scientists in the field of nutrition and exercise discussed the ergogenic properties of various nutritional interventions and presented research to show that dietary strategies can be applied to extend the limits of human...

... the effect of Tai Chi on aerobic capacity. Effect sizes (ESs) and95% confidence intervals were calculated using D-STAT software. The ES for each studywas weighted by the sample size and pooled variance. The effects of Tai Chi exercise on aerobiccapacity were calculated including study design, gender, age...

... Abstract The functional residual capacity (FRC) is the only static lungvolume measured routinely in infants. It can be measured usinginfant whole body plethysmography or one of several gas dilutiontests. While plethysmography measures all compressiblegas within the thorax, the gas dilution...

... Abstract Transfer of oxygen and carbon dioxide over the alveolocapillarymembrane is the main function of the lungs and can bemeasured by the diffusing capacity for carbon monoxide (CO).CO has a high affinity for hemoglobin and is absent inpulmonary capillary blood. After inspiration CO diffuses...

... Abstract The impact of genetic factors on laryngeal cancer risk was studied in relation to DNA repair capacity on the phenotypic and genotypic level. DNA lesions induced by bleomycin or S9-activated benzo[a]pyrene were determined in blood lymphocytes using the alkaline comet assay. Laryngeal...
