The present study was designed to initially test a model of the role of a set of cognitive (namely, aptitude and working memory) and motivational (namely, language learning goals, self-efficacy beliefs and self-regulation strategy use) individual differences variables in writing performance of a group of Iranian undergraduate EFL learners and, subsequently, to identify the possible differences ...

Progress on data integration has come to the point that we must deal with the need of semantic integration. In this work we present a prototype of an integration tool of information sources (Semantic Integration Tool for Spatial Data). It focuses on schema integration of spatial databases. This tool is able to recognize the similarities and the differences between entities to be integrated. It ...

Intraperitoneal injection of ethionine to male rats for up to 12 days caused a pronounced fall in S-adenosylmethionine (AdoMet) in liver, but did not or only slightly affect AdoMet in kidney and spleen. Liver and to a lesser degree kidney showed a dose-dependent, massive accumulation of the metabolic product, S-adenosylethionine (AdoEth), and this metabolic response was most pronounced within t...

The influence of the environment and genetics on individual biological characteristics, such as body mass and stature is well known. Many studies of these relationships have been based on conscript data. These studies often suffer from the fact that their data cover only a part of the population. Characterized by prosperity, democratic stability and enormous micro-regional cultural diversity, S...

OBJECTIVES Twin studies present a unique opportunity to examine the association of birth weight with adult life phenotypes in a design that naturally accounts for maternal factors and a range of early environmental factors, which might potentially bias the association. In this study, we explored the association of birth weight with osteoporosis (OP) and osteoarthritis (OA), in a large national ...

Annual measurements on growth traits from a total of 275 parents and 690 full-sib families from 23 diallel tests of loblolly pine (Pinus taeda L.) in the Northern, Coastal and Piedmont test regions of the southeastern U.S. were used to reveal the time trend of genetic parameters through age 8. Variance components were estimated from mixed model analyses on growth traits (height, DBH and volume)...
