we aimed to evaluate the potential of growing rats as a model of osteoporosis induced by short term hypercholesterolemia. twelve growing female sprague-dawley rats were randomly allocated into two groups. control rats received standard diet while rats in group 2 were fed with diet contained 20% sunflower oil, 2% cholesterol and 0.5% cholic acid for 2 weeks and then a diet contained 10% sunflowe...

abstract background: conflict is the lack of agreement and disagreement between the two men, and behavioral maladjustment or objectives that are in opposition to the other. destructive conflicts are incidents imposed on one or more than one member of the family or the whole family and affect on them. the purpose of this research is to study the effect of solution - focused short-term approach o...

Color-based object selection - for instance, looking for ripe tomatoes in the market - places demands on both perceptual and memory processes: it is necessary to form a stable perceptual estimate of surface color from a variable visual signal, as well as to retain multiple perceptual estimates in memory while comparing objects. Nevertheless, perceptual and memory processes in the color domain a...

Psychological studies of animal choice show that the immediate consequences of choice strongly influence preference. In contrast, evolutionary models emphasize the longer-term fitness consequences of choice. Building on recent work by Stephens & Anderson (2001, Behavioral Ecology 12, 330–339), this study presents two experiments that address this conflict. Stephens & Anderson developed an alter...

Modern neuroscientific research help to solve the impotent challenge in curriculum design and teaching for enhancing students’ ability to organize information in a way that makes it efficient in response to an appropriate context such as problem solving and critical thinking via knowing about the mechanism of different type of memories especially long term memory. At first, we should to c...

review and classification of electric load forecasting (lf) techniques based on artificial neuralnetworks (ann) is presented. a basic anns architectures used in lf reviewed. a wide range of annoriented applications for forecasting are given in the literature. these are classified into five groups:(1) anns in short-term lf, (2) anns in mid-term lf, (3) anns in long-term lf, (4) hybrid anns inlf,...

In this article, 7 evolutionary hypotheses about the context-specific nature of mate attraction effectiveness were empirically tested and supported. In the context of short-term mating, for example, men have faced the adaptive problem of finding sexually accessible women. As a result, men express a preference for sexually availability in short-term mates. In Studies 1 and 2, separate groups of ...
