I. Introduction The high prices for electricity in California during the summer of 2000 led to a substantial amount of regulatory and political intervention. Price caps were lowered and the Federal Energy Regulatory Commission (FERC) proposed that a new type of " soft-cap " auction be adopted to replace the uniform price auction. This auction combines a standard uniform price auction with a dis...

Appropriate and acceptable prediction of bed load being carried by streams is vitally important for water resources quantity and quality studies. Although measuring the rate of bed load in situ is the most consistent method, it is very expensive and cannot be conducted for as many streams as the measurement of suspended sediment load. Therefore, in this study the role of suspended load on bedlo...

Photovoltaic power generation system implements an effective utilization of solar energy, but generally has very low conversion efficiency. Maximum power point tracking (MPPT) is used in photovoltaic (PV) systems to maximize the photovoltaic array output power, irrespective of the temperature and irradiation conditions and of the load electrical characteristics. A MPPT system has been developed...

In this study, the effect of slip casting parameters on the ultrafine microstructure and the density of pore-free YAG ceramic was evaluated. A stable, high concentrated aqueous YAG slurry using Dolapix-CE64 as a dispersant was prepared. The effect of dispersant concentration as well as the solid load on the stability and rheological behavior of the slurry was also studied. The optimal dispersan...

BACKGROUND AND AIMS There are many edentulous people with severely resorbed residual ridges and non-resilient lin-ing mucosa that are unable to tolerate occlusal forces during functional and parafunctional movements. Lining the tissue surface of dentures with a flexible material can theoretically distribute and absorb forces with cushioning effect. The aim of this study was to evaluate the effe...

BACKGROUND The effect of low-dose gamma irradiation on healing of soft tissue allografts remains largely unknown. HYPOTHESIS The authors hypothesized that soft tissue allograft healing to bone would be delayed compared with that of autograft tissue and that low-dose (1.2 Mrad) gamma irradiation would not affect the healing response of allograft tissue after anterior cruciate ligament (ACL) re...

abstract: objective: giant cell tumor of soft parts is a rare neoplasm that mainly affects adulst and the elderly and is usually located in the extremities. here we report a child with giant cell tumor of soft tissue, which is a very rare condition in childhood. clinical presentation: a 5 year old girl presented with a 5 month history of left lower extremity pain. she had developed paraplegia b...

The load on a Web server depends on the behavior of users, both individually and in the aggregate. The behavior of the individual user includes abandoning a site that is too slow; this is both a vital result of site performance and a variable that affects the shape of the load on a site. The behavior of a population of users causes variance in the instantaneous load on a Web server, which stron...
