Back Cover: The blood plasma protein fibrinogen can assemble into fibers in vitro based on different mechanisms. Self-assembly is either induced by denaturing buffers, non-denaturing buffers or substrate interactions. Understanding how these factors influence fibrillogenesis important for developing fibrinogen-based biomaterials with fibrous architecture future tissue engineering applications. ...

Watershed analyses of nutrient removal in riparian buffers have been limited by the geographic methods used to map buffers and by the statistical models used to test and quantify buffer effects on stream nutrient levels. We combined geographic methods that account for buffer prevalence along flow paths connecting croplands to streams with improved statistical models to test for buffer effects o...

watershed scale irnpact. Our objective was to estimate the watershed scale impact of grass buEers by comparing sediment and agichemical losses from two adjacent 14 1 165 hectare watersheds, one with conservation buffers and one without. Rainfall derived m o f f events frorn 2002-2003 were monitored for water runoff, TSS, phosphorous and atrazine loss. A conservation-watershed included 0.8 Ism o...

In IC designs which incorporate multiple power supply voltages, the interfacing of signals between blocks with different power supplies can be achieved through I/O buffer circuits, which demand high-performance as well as ESD protection for the inputs and outputs. High performance buffers are also desirable for intra-chip interfacing for technologies that require multiple supply voltages. This ...

Objective: In Persian medicine (PM), wet-cupping therapy (WCT) is the most utilized approach. WCT is mostly done between the shoulders, which is referred to as “hejamt-e-aam” in the Persian language. CD4+T cells also refer to T helper lymphocytes play a critical role in the immune system. Naïve CD4+ T cells differentiate into at least four subsets, T helper 1 (Th1), T helper 2 (Th2), T helper 1...

Despite increased attention and demand for the adoption of agroforestry practices throughout the world, rigorous long-term scientific studies confirming environmental benefits from the use of agroforestry practices are limited. The objective was to examine nonpoint-source pollution (NPSP) reduction as influenced by agroforestry buffers in watersheds under grazing and row crop management. The gr...

A number of recent reports indicate the existence of more than one type of helper T cell (I-6). A previous publication from our laboratory (3) demonstrated two types of carrier-specific helper T cells that independently and synergistically exert helper effects on the hapten-specific antibody response. One type (Thl) 1 is a more conventional helper T cell that helps hapten-specific B cells only ...

The correctness of applications that perform asynchronous message passing typically relies on the underlying hardware having a sufficient amount of memory (message buffers) to hold all undelivered messages—such applications may deadlock when executed on a system with an insufficient number of message buffers. Thus, determining the minimum number of buffers that an application needs to prevent d...

Given a spatial network, a spatial neighbourhood, a collection of activities, a constant buffer area and a number of clusters to identify (k), the problem of spatial activity summarization using constant area buffers is to choose the user defined k constant area buffers which maximizes the number of activities covered. Spatial activity summarization is an important societal problem and has been...
