[57] ABSTRACT A ?exible system for determining the quality of agricul tural products based on characteristics such as, for ex ample, mass, shape, hardness, size, color and surface texture is disclosed herein. The quality determination apparatus includes a feeder assembly for sequentially dropping individual product samples upon an impact transducer arrangement. The impact transducer gener ates ...

This paper aims to describe different approaches for studying the overall diet with advantages and limitations. Studies of the overall diet have emerged because the relationship between dietary intake and health is very complex with all kinds of interactions. These cannot be captured well by studying single dietary components. Three main approaches to study the overall diet can be distinguished...

the spreading activation models of mental lexicon's structure have presented the lexicon in multiple layers (semantic- syntactic- phonological). each layer is a network of nodes which are associated by links. the nature of these links is different from layer to layer. the literature for english speakers has shown that in the phonological layer, phonological forms of words have been linked based...

Tolbutamide and gliclazide block the KATP channel Kir6.2/Sur1, causing membrane depolarization and stimulating insulin secretion in pancreatic beta cells. We examined the ability of the EPAC-selective cAMP analog 8-pCPT-29-O-Me-cAMP-AM to potentiate the action of these drugs and the mechanism that might account for it. Insulin secretion stimulated by both 200 mM tolbutamide and 20 mM gliclazide...

HIV resistance to antiretroviral agents is a major contributory cause of treatment failure. The dynamics of HIV replication, together with patient-, physician-, and drug-related factors, lead to emergence of HIV resistant strains in most of the patients. Phenotypic assays look for an increase in the antiretroviral drug (ARV) concentration that inhibits 50% of the growth of the tested HIV strain...
