The aim was to assess mRNA and/or protein levels of heat shock proteins, cytokines, growth regulating, and metabolic proteins in myalgic muscle at rest and in response to work tasks and prolonged exercise training. A randomized controlled trial included 28 females with trapezius myalgia and 16 healthy controls. Those with myalgia performed ~7 hrs repetitive stressful work and were subsequently ...
This paper shows a theoretical study of the thermal properties of armchair grapehen nanoribbons in the presence of extended vacancies. Each graphene nanoribbons formed by superlattices with a periodic geometric structure, different size and symmetry of vacancies. The phonon dispersion, specific heat and thermal conductivity properties are described by a force-constant model and also by Landauer...
In this paper, we have presented the optimized BCS formalism using the isothermal probability distribution. The effect of statistical fluctuations on thermodynamical properties of nuclei has been investigated. The average gap parameter is calculated and then the energy, the entropy and the heat capacity are evaluated. The resulting values are compared with results of the standard BCS and the ...

Banerjee In this study, we report the anomalous enhancement of specific heat capacity of high-temperature nanofluids. Alkali metal chloride salt eutectics were doped with silica nanoparticles at 1% mass concentra...
For the last few years, molten salt nanomaterials have attracted many scientists for their enhanced specific heat by doping a minute concentration of nanoparticles (up to 1% by weight). Likewise, enhancing the specific heat of liquid media is important in many aspects of engineering such as engine oil, coolant, and lubricant. However, such enhancement in specific heat was only observed for molt...
In this study Bis(1,4-dinitro toprop-2-yl) Nitramine, BNA, was attached to boron nitride nano- cages (B12N12). , thermodynamic parameters of BNA with B12N12 have been computed using one of the methods of density functional theory (B3LYP) In the temperature variety 300 to 400 K each 10 degree one times, were calculated. So these materials were geometrically optimized. After that thermodynamic pa...
The composition of background electrolyte (BGE) in capillary electrophoresis (CE) is important for both selectivity and efficiency. Although the importance of pH and ionic strength predominates, attention should also be paid to specific conductivity, heat dissipation and buffering capacity. At a given pH/ionic strength combination, several buffers can in principle be used. Preference should be ...
Previous heat capacity estimators useful in path integral simulations have variances that grow with the number of path variables included. In the present work a new specific heat estimator for Fourier path integral Monte Carlo simulations is derived using methods similar to those used in developing virial energy estimators. The resulting heat capacity estimator has a variance that is roughly in...
We use heat-capacity measurements as a function of field rotation to identify the nodal gap structure of CeIrIn(5) at pressures to 2.05 GPa, deep inside its superconducting dome. A fourfold oscillation in the heat capacity at 0.3 K is observed for all pressures, but with its sign reversed between 1.50 and 0.90 GPa. On the basis of recent theoretical models for the field-angle-dependent specific...
In this research of cis, trans and vinyl monomeric derivatives of 1,4-butadiene were studied using C20 in different temperatures by Functional density theory (DFT). To this purpose, the materials were firstly optimized geometrically, then the calculations of the thermodynamic parameters were performed on all of them. In the following, changes in parameters of energy...
