A numerical analysis was performed as to investigate the heat transfer characteristics of an evaporating thin-film meniscus. A mathematical model was used in the formulation of a third order ordinary differential equation. This equation governs the evaporating thinfilm through use of continuity, momentum, energy equations and the Kelvin-Clapeyron model. This governing equation was treated as an initial value problem and was solved numerically using a Runge-Kutta technique. The numerical model uses varying thermophysical properties and boundary conditions such as channel width, applied...

It is well known that the class of steroid hormones known as estrogens have powerful effects on organs related to reproduction such as the uterus and the breast. What is less well known is that estrogens also profoundly modulate brain function and behavior. Estrogens, such as estradiol, can occur in brain as the result of ovarian secretion of the hormone into the blood that then finds its way to the brain. In male vertebrates, the testes secrete androgens, such as testosterone, into the blood and this class of steroid hormones can be converted into estrogens in the brain via the action of the...

With the ascension of the Liberal and Progressive stranglehold of our government in both Houses of congress Middle class Americans find themselves under siege. Global Warming rhetoric has hit a crescendo and in his new book "Global Warming...Really?" Gregory Parker blends common sense and facts to address the issue of our time. Joe Bastardi noted Meteorologist said: "I couldn't put it down......easy to read and understand book sums up the entire global warming debate... the best traditions of the citizen soldier..."

This volume provides a basic framework for using visual data - namely still photographs - as a tool for social analysis. The authors determine the importance of theoretical assumptions in analysing these data and provide advice on how to use photographs in cognitive, symbolist and structuralist research.
