the purpose of this study was to determine the relationship between blood buffer capacity and aerobic power (vo2max) with ability to perform high intensity intermittent activities in young football players. methods: 27 male football players (age 17.66 ±0.49 years) selected as subjects. blood samples were collected before and after the yoyo intermittent test. then, after 48 hours, the bruce trea...

The pH of airway epithelial secretions influences bacterial killing and mucus properties and is reduced by acidic pollutants, gastric reflux, and respiratory diseases such as cystic fibrosis (CF). The effect of acute acid loads depends on buffer capacity, however the buffering of airway secretions has not been well characterized. In this work we develop a method for titrating micro-scale (30 μl...

OBJECTIVE. The purpose of this study is to evaluate the ability of two commercial strip tests and laboratory titration to detect saliva buffer capacity. MATERIALS AND METHODS. Sixty-four patients were examined. Stimulated saliva was collected and buffer capacity was determined with two different chair-side strip tests in addition to immediate transportation to the laboratory to check the buffer...

The generalized concept of 'dynamic' buffer capacity βV is related to electrolytic systems of different complexity where acid-base equilibria are involved. The resulting formulas are presented in a uniform and consistent form. The detailed calculations are related to two Britton-Robinson buffers, taken as examples.

We study the effect of adding redundancy to an input stream on the losses that occur due to buffer overflow. We consider several sessions that generate traffic into a finite capacity queue. Using multi-dimensional probability generating functions, we derive analytical formulas for the loss probabilities and provide asymptotic analysis (for large n and small or large 2). Our analysis allows us t...
