BACKGROUND AND PURPOSE Conventional imaging lacks sensitivity and specificity for the detection of early subcortical cerebral infarction. The purposes of our study were (1) to determine the accuracy of diffusion-weighted (DW) MRI for early subcortical infarction and (2) to determine the efficacy of DW MRI for differentiating acute from nonacute subcortical infarctions when conventional MR demon...

Historically, economic changes have negatively affected the nursing workforce in Ontario. The trend towards part-time and casual employment emerged from healthcare restructuring in the 1990s. The severe acute respiratory syndrome (SARS) outbreak in 2003 alerted the Ontario government to the issue of part-time and casual nursing. In 2007, the Nursing Graduate Guarantee (NGG), a health human reso...

Effects of additional nitrate (20 mol m·3 NO;) on growth of barley (Hordeum vulgare L. cv. Triumph), oat (Avena sativa L. cv. Amuri), rye (Secale cereale L. cv. Rapaki), triticale (x Triticosecale Wittm. cv. Aranui) and wheat (Triticum aestivum L. cv. Otane) prior to emergence from a sowing depth of 70 mm were examined under controlled environment. conditions. For all five cereals, additional N...

The aim of this study was to determine the variation of phenolic compounds in common and tartary buckwheats collected from China, Japan and Korea. Two buckwheat varieties of each country were cultivated using nutrient solution and vermiculite in the greenhouse from February to May, 2012 and harvested at twoweek intervals. Phenolics such as chlorogenic acid, C-glycosylflavones (orientin, isoorie...

Nutritional value of freshwater mesozooplankton, fatty acid (FA) and amino acid (AA) compositions were determined in the middle of each season for a one-year period from May 2009 to February 2010 in Hanna Dam Lake, Isfahan, Iran. FA and AA composition significantly (P < 0.05) varied in relation to the seasonal changes of water quality, phytoplankton and zooplankton community. The content of sat...

The GridTrust Security Framework (GSF) offers security and trust management for the next generation Grids (NGG). It follows a vertical approach for Grid security from requirements level right down to application and middleware levels. New access control models for collaborative computing, such as the usage control model (UCON), are implemented for securing the Grid systems. The GSF is composed ...

Wide distribution of chlorinated paraffins in the environment has already been demonstrated in several studies; however, information about their levels in the Central Europe is still very limited. First study focused on the SCCP contamination of the Czech aquatic environment have been performed recently, and its results motivated the authors to analyze sediments from a wide set of the Czech riv...

Data and information in the development of digital technology have an important role. Every activity or that uses is related to data information, so security confidentiality are very important. To maintain confidentiality, protection with cryptographic techniques needed. Cryptographic encryption, which where process scrambling carried out hiding a key system, while decryption changing condition...
