The appearance of osteoporosis in elders and the growth of the frequency which it is diagnosed with as we approach patients who are older and older, makes this health problem very important in the societies in which a high number of persons reach old age. These societies, usually belonging to economically advanced jurisdictions, are the first interested in the way health expenses can balance th...

Chemical analyses of rapeseed are expensive and time consuming, thus for quick analyses of breeding materials it is necessary to use physical methods. NIR analysis was applied for analysis of glucosinolates. Calibration equations were calculated for total content of glucosinolates and for individual glucosinolates. The calibration database covers 300 samples collected in IHAR during last 3 year...

Surveys found that large contractors replace approximately 10% of their equipment fleet units annually in North America. Cost minimization model is a commonly accepted method for equipment replacement which helps to identify these equipment units whose total owning and operating cost reaches their minimum point as candidates for replacement. While the model is conceptually clear with the aim of...

Running economy (RE) has a strong relationship with running performance, and modifiable running biomechanics are a determining factor of RE. The purposes of this review were to (1) examine the intrinsic and extrinsic modifiable biomechanical factors affecting RE; (2) assess training-induced changes in RE and running biomechanics; (3) evaluate whether an economical running technique can be recom...

This paper promotes a social-cognitive framework to categorise those factors that enhance self-evaluation. These factors include social messages, personal factors and situational factors in the self-evaluation context. In addition, some technical issues with the accuracy of self-evaluations are outlined. These related to (a) the adequacy of the criterion, (b) the method of statistical compariso...

this research was investigated to study relationship among seed yield, seed yield components and morphological traits and their direct and indirect effects on seed yield of 100 safflower genotypes in two water environments (normal and drought stress) at research farm of isfahan university of technology during 2012. seed yield had positive correlation with number of head per plant, seed per head...

About at the break of sixties and seventies of this century the first functional and publicly used information system developed from originally experimental and non commercial applications of computer technology in storing and retrieval of document records. At the beginning these were mostly parallel editions of bibliographies in both printed and magnetic format. Thus developed on one hand data...

In the economical caching problem, an online algorithm is given a sequence of prices for a certain commodity. The algorithm has to manage a buffer of fixed capacity over time. We assume that time proceeds in discrete steps. In step i, the commodity is available at price ci ∈ [α, β], where β > α ≥ 0 and ci ∈ N. One unit of the commodity is consumed per step. The algorithm can buy this unit at th...
