We extend the quantum theory of dissipation in the context of system-reservoir model, where the reservoir in question is kept in a nonequilibrium condition. Based on a systematic separation of time scales involved in the dynamics, appropriate generalizations of the fluctuationdissipation and Einstein’s relations have been pointed out. We show that the Wigner-Weisskopf decay of the system mode r...

The function of the arteries as an elastic reservoir between the heart and the capillaries is reviewed. The appropriateness of selecting the exit from this reservoir as the point for estimating its effective pressure is shown. The technique for taking the pressure here by the method of Gaertner is described and its advantage and certain apparent disadvantages are indicated. The technique of Gae...

The first goal of this modeling exercise was to model the rate of smolt migration and survival of different life history types of chinook salmon through a reservoir in the Snake River. The second goal was to use the model to help understand how physical and behavioral processes control the fish migration and survival. An applied goal is to predict the effects of Snake River Reservoir drawdown o...

The pikeperch Sander lucioperca (L.) is present in numerous French water bodies. However, few studies have focused on the biology and ecology of the species and, as a result, references are lacking to assess its adaptation to lacustrine environments. The growth and diet of pikeperch were investigated in two reservoirs located in southern France. The fish at both sites show similar growth rates ...

a key parameter for the application of polymer gels in water shut off treatment is the adsorption of polymer gel onto the rock surface. so, the adsorption properties of a nanocomposite hydrogel were discussed in this research by crosslinking of sulfonated polyacrylamide/sodium montmorillonite aqueous solutions with chromium triacetate. the x-ray diffraction patterns indicated that exfoliated ty...

which states that the increase in the entropy of a system, when it changes from one condition to another, cannot be less than the integral of the heat absorbed divided for each increment of heat by the temperature of a heat reservoir appropriate for supplying the increment in question. The equality sign in this expression is to be taken as applying to the limiting case of reversible changes.” F...

This paper describes a determination of critical gas saturations and relative permeabilities relevant to the depressurisation of two North Sea fields. A series of reservoir condition coreflood experiments and associated numerical simulations is described. Four experiments were conducted with aged cores and fluids and each comprised of a waterflood, followed by depressurisation at different rate...

In the upper jaw, a cross-arch implant-supported fixed restoration was delivered. In the lower jaw, an implant-supported fixed partial prosthesis was provided, retaining some natural dentition, which increased the risk of a periodontal reservoir. Treatment included multiple extractions and submerged implants. Implant survival rate, patient satisfaction, marginal bone maintenance and soft-tissue...

Declining reservoir storage has raised the specter of the first water shortage on the Lower Colorado River since the completion of Glen Canyon and Hoover Dams. This focusing event spurred modeling efforts to frame alternatives for managing the reservoir system during prolonged droughts. This paper addresses the management challenges that arise when using modeling tools to manage water scarcity ...
