at the beginning of this paper, design and manufacturing stages of the 3 degree of freedom test stand for a remotely piloted helicopter is described, in which the helicopter is able to rotate about its three primary accesses. in the next parts the dynamical model of the rph in the yaw channel is presented and lateral transfer function of rph (yaw channel) is extracted by performing several test...

quantitative relationships between molecular structure of forty eight aldehyde compounds with their known cathepsin k inhibitory effects were discovered by partial least squares (pls) method. evaluation of a test set of 10 compounds with the developed pls model revealed that this model is reliable with a good predictability. since the qsar study was performed on the basis of theoretical descrip...

We attempt to answer why sex is nearly ubiquitous when asexual reproduction is ostensibly more efficient than sexual reproduction. From the perspective of a genetic allele, each individual bearing that allele is akin to a stock share yielding dividends equal to that individual’s number of offspring, and the totality of individuals bearing the allele is its portfolio investment. Alleles compete ...

background: lifestyle-modification programs including physical activity are essential for both treatment and prevention of type 2 diabetes mellitus ( t2dm ). however, factors associated with physical activity among patients are poorly understood. this study applied social-cognitive theory (sct) for predicting determinants of physical activity among women with t2dm in iran, 2013. methods: in thi...

Biological lifestyle factors (BLFs) such as physical activity, sleep, and nutrition play a role in cognitive functioning. Research concerning the relation between BLFs and cognitive performance is scarce however, especially in young and middle-aged adults. Research has not yet focused on a multidisciplinary approach with respect to this relation in the abovementioned population, where lifestyle...
