In an earlier study we showed that a blend of thermoresponsive and nonthermoresponsive hydroxyalkylcelluloses could be used to create a thermally tunable polymer network for double-stranded (ds) DNA separation. Here, we show the generality of this approach using a family of polymers suited to a wider range of DNA separations: a blended mixture of N,N-dialkylacrylamide copolymers with different ...

implant and DMPA appears increasingly important in light of one recent animal study suggesting a relationship between progestin exposure and vaginal atrophy (which might lead to increased risk of HIV infection).6 Although it is premature to extrapolate the findings of this study to humans, the results highlight the importance of correct and consistent condom use among users of hormonal contrace...

The present study investigated the relative contribution of four characteristics to attractiveness of the female body: waist-to-hip ratio (WHR), breasts, buttocks and thighs. Using a program for computer animation (DAZ 3D) 81 female figures were generated. Figures were created as combinations of 4 characteristics  3 equidistant sizes (small, medium and large). Participants (N=260) of both gend...

‎Bucket recursive trees are an interesting and natural‎ ‎generalization of ordinary recursive trees and have a connection‎ to mathematical chemistry‎. ‎In this paper‎, ‎we give the lower and upper bounds for the moment generating‎ ‎function and moments of the multiplicative Zagreb indices in a‎ ‎randomly chosen bucket recursive tree of size $n$ with maximal bucket size $bgeq1$‎. Also, ‎we consi...

a watching system in a graph $g=(v, e)$ is a set $w={omega_{1}, omega_{2}, cdots, omega_{k}}$, where $omega_{i}=(v_{i}, z_{i}), v_{i}in v$ and $z_{i}$ is a subset of closed neighborhood of $v_{i}$ such that the sets $l_{w}(v)={omega_{i}: vin omega_{i}}$ are non-empty and distinct, for any $vin v$. in this paper, we study the watching systems of line graph $k_{n}$ which is called triangular grap...
