(University of Missouri-Columbia) A leading researcher of media effects on body image at the University of Missouri looked at the effect of male magazines on college-age men. Completing three different studies, Jennifer Aubrey, assistant professor of communication in the College of Arts and Science, found that unlike their female classmates, it was not the same-sex models that affected the males negatively, but quite the opposite.

| • | Surface Water Suitability for Drinking Purpose in Cholistan Desert |
| The desert dwellers in Cholistan desert use surface water collected in natural depressions or dugout ponds `Tobas` since the groundwater is brackish and not fit for human consumption especially for drinking purpose. The present study was conducted in cholistan desert to evaluate the quality of rainwater harvested in low lying areas or dugout ponds the only source of drinking water for humans as well as their livestock. Water samples were collected from 10 tobas of lesser Cholistan since most of the tobas were dried up due to the drought conditions. These samples were analyzed to quantify different parameters i.e. pH, HT, TDS, Alkalinity, Ca, Mg, Na, K, Fe, Zn, Cd, Cr, Cu, Sr, Ni, Pb, Co, Cl, PO4, SO4, CO3--, HCO3- and NO3 relating the water quality. The results showed that most of the parameters were found within the WHO recommended levels determining the suitability of this water for drinking purpose. However, Chemical Oxygen Demand (COD) concentration was found high indicating undesirable presence of organic matter. Higher concentration of Sr was found demanding future detailed study of drinking water in Cholistan. | |

| • | The velocity of the arterial pulse wave: a viscous-fluid shock wave in an elastic tube |
| Background: The arterial pulse is a viscous-fluid shock wave that is initiated by blood ejected from the heart. This wave travels away from the heart at a speed termed the pulse wave velocity (PWV). The PWV increases during the course of a number of diseases, and this increase is often attributed to arterial stiffness. As the pulse wave approaches a point in an artery, the pressure rises as does the pressure gradient. This pressure gradient increases the rate of blood flow ahead of the wave. The rate of blood flow ahead of the wave decreases with distance because the pressure gradient also decreases with distance ahead of the wave. Consequently, the amount of blood per unit length in a segment of an artery increases ahead of the wave, and this increase stretches the wall of the artery. As a result, the tension in the wall increases, and this results in an increase in the pressure of blood in the artery. Methods: An expression for the PWV is derived from an equation describing the flow-pressure coupling (FPC) for a pulse wave in an incompressible, viscous fluid in an elastic tube. The initial increase in force of the fluid in the tube is described by an increasing exponential function of time. The relationship between force gradient and fluid flow is approximated by an expression known to hold for a rigid tube. Results: For large arteries, the PWV derived by this method agrees with the Korteweg-Moens equation for the PWV in a non-viscous fluid. For small arteries, the PWV is approximately proportional to the Korteweg-Moens velocity divided by the radius of the artery. The PWV in small arteries is also predicted to increase when the specific rate of increase in pressure as a function of time decreases. This rate decreases with increasing myocardial ischemia, suggesting an explanation for the observation that an increase in the PWV is a predictor of future myocardial infarction. The derivation of the equation for the PWV that has been used for more than fifty years is analyzed and shown to yield predictions that do not appear to be correct. Conclusion: Contrary to the theory used for more than fifty years to predict the PWV, it speeds up as arteries become smaller and smaller. Furthermore, an increase in the PWV in some cases may be due to decreasing force of myocardial contraction rather than arterial stiffness. | |
