Problems of stress

In this report, we examine the unsteady Stokes equations with nonhomogeneous boundary conditions. As an application of a Carleman estimate, we first establish log type stabilities for the solution of the equations from either an interior measurement of the velocity, or a boundary observation depending on the trace of the velocity and of the Cauchy stress tensor measurements on a part of the boundary.

Different types of halophiles have solved the problem how to hope with salt stress (and often with other forms of stress as well) in different ways, so that the study of microbial life at high salt concentrations can answer many basic questions on the adaptation of microorganisms to their environments. Most known halophiles are relatively easy to grow, and genera such as Halobacterium, Haloferax.

INTRODUCTION Contrary to popular belief, pharmacy is not limited to counting and dispensing pills. Pharmacy is a rewarding profession in the health care system that involves working closely with doctors and patients. No matter what health field you step into, there will always be a need for pharmacists. They provide their expertise on the composition, use, and manufacturing of a drug, as well as its physiological and chemical interactions. Pharmacy offers flexible work schedules, a broad spectrum of opportunities, direct patient contact, and top salaries right out of college!...

In this chapter we will consider an important class of problems in which the fluid is either at rest or moving in such a manner that there is no relative motion between adjacent particles. In both instances there will be no shearing stresses in the fluid, and the only forces that develop on the surfaces of the particles will be due to the pressure. Thus, our principal concern is to investigate pressure and its variation throughout a fluid and the effect of pressure on submerged surfaces. The absence of shearing stresses greatly simplifies the analysis and, as we will see,...
