background: mdm2 (murine double minute2) is an oncoprotein that inhibits the p53 activity. overexpression of mdm2 gene has been reported in several human tumors. in the present study, we aimed to evaluate the impact of 40-bp insertion/deletion (ins/del) polymorphism on the promoter of mdm2 and susceptibility to breast cancer in a sample of iranian population. methods: this case-control study wa...

let $g$ be a connected graph, and let $d[g]$ denote the double graph of $g$. in this paper, we first derive closed-form formulas for different distance based topological indices for $d[g]$ in terms of that of $g$. finally, as illustration examples, for several special kind of graphs, such as, the complete graph, the path, the cycle, etc., the explicit formulas for some distance based topologica...

in this work, we dissect the performance of  two modern perdew-burke-ernzerhof (pbe)-based double-hybrid (dh) density functionals to predict the isotropic and anisotropic polarizabilities of water nanoclusters (h2o)n [n = 2-6]. the considered models include the cubic integrand (ci) and quadratic integrand (qi) functions as well as the spin-opposite-scaled (sos) scheme for perturbative correlati...

background: sputum smear examination is the basis of diagnosis of tuberculosis and quality control for the correct diagno­sis of tuberculosis is necessary. this study was a method survey and performed with 930 smears with the aim to compare the confidence rate of sputum smear examination reported by one laboratory technician with the findings reported by two techni­cians in a tuberculosis scree...

An elemental powder sintering (EPS) technique has been developed for the synthesis of porous NiTi alloy, in which Ni and Ti powders are used as the reactants and TiH2 powder is added as a pore-forming agent and active agent. Effects of various experimental parameters (sintering temperature, sintering time, and TiH2 content) on the porosity, pore size and pore distribution as well as phase compo...

the goal of this paper is to generalize the recently introduced summability method and introduce double statistical convergence of order  by using ideal. we also investigate certain properties of this convergence.

It has been widely reported that the sintering productivity and bed permeability would be reduced when adopting ultra-deep sintering. To solve aforementioned problems, double-layer process with stand-support (DLSP-S) is proposed in this research to achieve of a 1000 mm bed. The results showed compared process, DLSP-S improved yield from 64.53% 1.76 t·m−2·h−1 66.74% 2.12 t·m−2·h−1, respectively....

BACKGROUND In response to the rapid aging of the population in Japan, many care systems have been created in quick succession. Establishment of discharge planning departments (DPDs) in hospitals is one of them. In this study, we compared the distribution and characteristics of DPDs and the characteristics of the hospitals that have DPDs between 2001 and 2010 in Japan. METHODS We mailed a ques...

In this work, pellet samples of barium calcium zirconate titanate (Ba1-xCaxZr0.1Ti0.9O3, x=0.065) were prepared using solid state reaction route with double sintering. The structural and piezoelectric properties measured. Further, SEM EDAX analysis observed. With different sintering temperature, the density grain size changed further, their effect in has been For samples, converse constant (d33...
