BACKGROUND Because randomized cancer screening trials are very expensive, observational cancer screening studies can play an important role in the early phases of screening evaluation. Periodic screening evaluation (PSE) is a methodology for estimating the reduction in population cancer mortality from data on subjects who receive regularly scheduled screens. Although PSE does not require assump...

abstract main objective of this paper is the investigation the effect of support policies of government on income risk of poultry producers in iran for the 1989-2006. ccv index was used to investigate amount of variation that cause each support policies (market price support, support of agricultural inputs, outputs insurance) on income risk variation of producers. the results of this study show...

The development of pale, soft, and exudative (PSE) breast fillet meat has become an economic burden for the poultry industry worldwide. PSE meat results in 1.0-1.5% loss in moisture and carcass weight, and a 2010 estimate of the Brazilian annual production put the economic loss due to PSE at over US$30 million. In the USA, PSE has caused an annual loss of up to US$200 million to the poultry ind...

Following the common use of of commodity hardware to build clusters, we argue that commodity software should be harnessed in a similar way to support Scientiic and Engineering work. Problem Solving Environments (PSE) provide the arena where commodity software technology can modernise the development and execution environment. We describe a PSE prototype based on the standard software infrastruc...

Putative protein sequences decoded from the messenger ribonucleic acid (mRNA) sequences are composed of twenty amino acids with different physical-chemical properties, such as hydrophobicity and hydrophilicity (uncharged, positively charged or negatively charged amino acids). In this paper, the power spectral estimate (PSE) technique for random processes is applied to the protein sequence match...

designed to support the development and execution of scalable parallel applications on clusters (farms) of distributedand shared-memory Alpha processors running the Digital UNIX operating system. PSE version 1.0 supports the High Performance Fortran (HPF) language; it also supplies generic facilities required by other parallel languages and systems. PSE provides tools to define a cluster of pro...

Covid-19 has led to renewed public support for services. Frontline workers symbolize a ideal of service ethos (PSE), though little attention been paid how the managers delivering vital services interpret and mobilize PSE. We show PSE is implemented by reflecting their local contexts. examine theoretical roots challenges newer theories management before illustrating its contemporary manifestatio...

Previous studies from our laboratory suggested that differential expression of genes between normal and pale, soft, and exudative (PSE) turkey is associated with development of the PSE syndrome. However, a detailed understanding of molecular mechanisms responsible for the development of this meat defect remains unclear. The objective of this study was to extend and complement our previous work ...

Plant sterol esters (PSE) reduce plasma low-density lipoprotein cholesterol concentration by inhibiting cholesterol absorption. Previous work in our laboratory indicated that PSE containing stearic acid (SA), compared to linoleic acid, were significantly more effective at reducing cholesterol absorption. We tested the cholesterol lowering properties of PSE containing fatty acids from beef tallo...

In this article, we estimate the vertical price transmission through the Iranian rice marketing chain by usingmonthly data from March 2000 to February, 2009 and error correction model (ECM).The causality testresults indicate that changes in the producer price clearly led changes in wholesale and retail prices. InProducer-Retail and Wholesale-Retail models, price transmission is asymmetric but i...
