Thermal contact resistance (TCR) of non-conforming rough surfaces is studied and a new analytical model is developed. TCR is considered as the superposition of macro and micro components accounting for the effects of surface curvature and roughness, respectively. The effects of roughness, load and radius of curvature on TCR are investigated. It is shown that there is a value of surface roughnes...

The flow method of reaction rate measurement has been adapted to the determination of the rate of diffusion of water into the human red cell. In seven experiments the half-time for diffusion exchange has been found to be 4.2 +/- 1.1 msec., which is equivalent to a diffusion flow of 8.6 x 10(-9) ml. H(2)O/(sec., red cell). This figure has been compared with the rate of water entrance under an os...

Counting lattice points inside a ball of large radius in Euclidean space is classical problem analytic number theory, dating back to Gauss. We propose variation on this problem: studying the asymptotics measure an integer affine planes ball. The first term volume ball; we study size remainder term. While equivalent counting eigenvalues Laplace operator torus, our corresponds integrated density ...

this paper deals with the threshold radius that warrants the use of single restraining rail for transit and railroads. different railways use different threshold radius from 91m to 365m to provide restraining rail. these threshold figures are probably experience driven choices. the need for restraining rail may be related to a so-called derailment alarm coefficient of 1.2 sustained over 2m leng...

background: considering the importance of an early diagnosis and proper decision-making in regards to the treatment of pediatric distal radius and elbow fractures, this study examines emergency medicine specialists’ accuracy in the diagnosis and treatment of these patients. methods: from 2012 and 2013, children less than 14 years old who were referred to an academic hospital emergency departmen...

the determination of gyration radius is a strong research for configuration of a macromolecule. italso reflects molecular compactness shape. in this work, to characterize the behavior of theprotein, we observe quantities such as the radius of gyration and the average energy. we studiedthe changes of these factors as a function of temperature for acetylcholine receptor protein in gasphase with n...
