nowadays knowledge of organizations is their most important assets. the importance of this intellectual property is very mush since the organizations' executive success without the management and proper use of this valuable resource, is difficult and sometimes impossible. so the only way to survive in the current competitive situations, is to implement appropriate knowledge management syst...

in this paper, an optimization method for both weight and displacement of composite blades is presented. in   order to hold issues such as aerodynamics and acoustic unchanged, airfoil shape during optimization process remained constant. to achieve the ultimate goal, only blade lamination was changed. in order to achieve minimum weight for each part of the structure, the lowest layers are foreca...

In this study, computational synthesis of carbon nanostructures' derivatives with TATB or 2,4,6-triamino-1,3,5- trinitrobenzene , which is an energetic substance in the temperature range of 300-400 K were evaluated by density functional theory method. In this regard, at the outset, the substances in the both sides of intended reactions for forming the desired products were optimized geometrical...

the present study examined the effect of endurance training on lipid profile, body weight and cardiovascular endurance in normal male rats after bunium persicum extract administration. 40 experimental male rats were divided into 5 groups: control, placebo, endurance training (et), bunium persicum extract administer (bpea) and et – bpea group. the exercise protocol was performed at a speed of 25...

Abstract The main hurdle in instrumentalizing agricultural soils to sequester atmospheric carbon is the development of methods measure soil stocks which are robust, scalable, and widely applicable. Our objective develop an approach that can help overcome these hurdles. In this paper, we present Wageningen Soil Carbon STOck pRotocol (SoilCASTOR). SoilCASTOR uses a novel fusing satellite data, di...

Cognitive abilities rise steeply from infancy to young adulthood and then are either maintained or decline to old age, depending on the specific ability. This pattern suggests corresponding continuities of mechanism and process, but it is striking that the fields of cognitive development and cognitive aging make little contact with each other's methods and theories. In this review we examine re...
