We examined if an exercise-heat acclimation program improves body fluid regulatory function in older subjects, as has been reported in younger subjects. Nine older (Old; 70 ± 3 yr) and six younger (Young; 25 ± 3 yr) male subjects participated in the study. Body fluid regulatory responses to an acute thermal dehydration challenge were examined before and after the 6-day acclimation session. Acut...

Swimming of fish and other animals results from interactions of rhythmic body movements with the surrounding fluid. This paper develops a model for the body-fluid interaction in undulatory swimming of leeches, where the body is represented by a chain of rigid links and the hydrodynamic force model is based on resistive and reactive force theories. The drag and added-mass coefficients for the fl...

Forensic RNA analysis is gathering pace with reports of messenger RNA analysis being used in case work, and with microRNA being increasingly researched. Such techniques address a fundamental issue in body fluid identification, namely increased specificity over existing chemical tests, and the incorporation of additional body fluids such as vaginal material. The use of RNA analysis will be of pa...

Abstract Evolution of three-dimensional body motion within surrounding fluid is addressed, each affecting the other significantly in a dynamic fluid–body interaction. This unsteady problem set near wall. The spatial three-dimensionality present new feature. For inviscid incompressible fluid, basic nonlinear formulation described, followed by linearised form as first exploration parameter space ...

Testosterone and 5 alpha-dihydrotestosterone (DHT) concentrations in tissue and body fluid were determined in adult male rats to investigate the mode of androgen distribution. The highest concentration of androgen (testosterone + DHT) and the smallest ratio of DHT/testosterone were observed in the intratesticular tissue fluid. The androgen concentration in testicular vein blood was much higher ...

BACKGROUND Transurethral resection of the prostate gland with irrigation fluid at room temperature leads to perioperative hypothermia which could give rise to adverse cardiovascular events in the perioperative period. The use of isothermic irrigation fluid reduces but does not eliminate this risk. Routine use of warm intravenous fluids along with isothermic irrigation had not been documented. T...

In this paper relationships have been derived for lift and drag coefficients for cylindrical bodies for two cases. The relative motion between the body and the fluid is assumed to be two-dimensional and to take place in a plane perpendicular to the axis of the body. Three-dimensional effects are ignored, thus limiting the validity of the formulae to low Reynolds number flows. The fluid is assum...

—This paper describes a framework for animating and controlling articulated bodies in a fluid simulation. We illustrate this approach by simulating an autonomous fish in various situations. Our little animal tries to reach a goal while its movement interacts with the fluid. Several algorithms allow the fish to automatically control its locomotion while taking into account the changing fluid for...
