bioactive food components (such as phenolic compounds, carotenoids, anthocyanins, tochopherols, ascorbic acid, flavonoids, minerals, enzymes and pectin) are active ingredients in food or dietary supplements, which proven to have an important role in health, and are safe for human consumption. these compounds exert their antioxidant effects by different mechanisms such as single electron transfe...

information accompanied with the technology supporting it is valuable asset in many organizations. as organizations are highly depended on it, implementing it effective governance is necessary for them. it governance areas affecting business are strategic alignment, risk management, performance management, resource management and providing value.  successful performances need a mix of structure...

fluency in a second language (l2) involves a quintessentially cognitive processing system that operates quickly and effectively. the perceived importance of researching fluency through a psycholinguistic lens has motivated the related l2 research to resort to current cognitive speaking-specific models. this study, drawing on levelt’s (1999a) psycholinguistic model, probed the deficiency sources...

Background: Researches on attachment theory shows that attachment styles influence marital adjustment. However, some psychological factors moderate this correlation. The present study was aimed to examine the moderating role of defense mechanisms in the association between attachment styles and levels of marital adjustment. Methods: This descriptive-correlational study collected data from a co...

this paper presents the results of a comprehensive study on the efficiency of planar parallel mechanisms, considering their kinetostatic performance and also, their workspace. this aim is approached upon proceeding single- and multi-objective optimization procedures. kinetostatic performances of ten different planar parallel mechanisms are analyzed by resorting to a recent index, kinematic sens...

in this work the kinetic data demanded for kinetic modeling were obtained in temperatures 350, 400, 450 and 500 oc by conducting experimentations on a fe-cr nanocatalyst prepared from a novel method and a commercial fe-cr-cu one. the collected data were subjected to kinetic modeling by using two models derived from redox and associative mechanisms as well as an empirical one. the coefficients o...
