Using classical molecular dynamics simulations, we have studied thermal boundary conductance (TBC) between a single-walled carbon nanotube (SWNT) and surrounding Lennard-Jones (LJ) fluids. With an aim to identify a general model that explains the TBC for various surrounding materials, TBC was calculated for three different surrounding LJ fluids, hydrogen, nitrogen, and argon in supercritical ph...

Matrix-assisted ultraviolet laser-desorption ionization time-of-flight mass spectrometry (UV-MALDI-TOF-MS) was applied to sulfated xylo-mannan fractions from Nothogenia fastigiata in order to determine their molecular weights and distribution profiles. The number-average molecular weight calculated from the spectra was similar to that determined by chemical end-group analysis for the lower mole...

background: dual-energy x-ray absorptiometry (dxa) is considered the gold standard for non-invasive measurement of bone mass. t-scores and z-scores are used to present the results of bone mass. the present study was designed to evaluate the discordance between t-scores and z-scores calculated at a same level and its relation with age, gender and body mass index (bmi) in a representative sample ...

the elementary reaction of kaon exclusive electroproduction on protons has been studied ina broad kinematical range. data for the calculation of the form factor of the kaon have been taken atdifferent values of the invariant center of mass energy w in the range w=1.8, 1.85, 1.98, 2.08 (gev), forone value of the transferred 4-momentum q2=2.35 (gev/c)2. in this analysis, we calculated σl and σt b...

The ultrasonic velocity, density and viscosity of some Schiff bases of 4-amino benzoic acid  were measured in 1,4-dioxane and dimethylformamide at 308.15 K. Various acoustical properties such as isentropic compressibility (ks), Rao’s molar sound function (Rm), the Van der Waals constant (b), molar compressibility (W), inter molecular free len...
