THE EFFECTS OF RESPIRATORY MUSCLE TRAINING ON VO2 MAX, THE VENTILATORY THRESHOLD AND PULMONARY FUNCTION. William E. Amonette, Terry L. Dupler. JEPonline. 2002;5(2):29-35. This study evaluated the effect of inspiratory and expiratory muscle training on pulmonary function and maximal exercise performance in competitive triathletes and marathon runners. The participants in this study (N=12) had a ...
The relatively recent detection of nitric oxide (NO) in the exhaled breath has prompted a great deal of experimentation in an effort to understand the pulmonary exchange dynamics. There has been very little progress in theoretical studies to assist in the interpretation of the experimental results. We have developed a two-compartment model of the lungs in an effort to explain several fundamenta...
air conditioning is widely applied for the improvement of standard of living in human life. this present investigation focused on the prediction of indoor air quality characteristics of air conditioned car using fuzzy logic algorithm. the conditioned space was selected and the experiments were planned as per design of experiments to study the effect of human load, fresh air supply and air veloc...
Effect of Grain Size on Radon Exhalation Rate from Calcium Silicate Rocks Using Alpha Track Detector
Large amounts of uranium, radium and radium products are redistributed throughout the environment owing to the use of phosphate fertilizers. Potential radiological impacts resulting from direct exposure, inhalation and ingestion of foods grown with fertilizers are discussed. This paper describes a simple method to measure exhalation rate of 222RN from phosphate fertilizers, clay and potatoes in...
The mainly sources for indoor radon concentrations in all types of houses are the soil radon flux under the building (about 80%) and the radon exhalation from building materials (about20%). Our paper presents two methods for simultaneous measurement of this exhalation from soil and building materials: (1) -charcoal adsorption, respectively (2)-Lucas cell method. The both methods are applicable ...
