2 Abstract In this paper the heat transport in microtubules (MT) is investigated. When the dimension of the structure is of the order of the de Broglie wave length the transport phenomena must be analyzed within quantum mechanics. In this paper we developed the Dirac type thermal equation for MT .The solution of the equation-the temperature fields for electrons can be wave type or diffusion typ...
In this study, using different station and up level atmospheric data, at first, statistical properties of the heat wave, occurred from 27 June to 27 July 2010, have been studied and then, using Ward cluster analysis, mentioned heat wave were classified to third period from severity point of view. Three classes of Iran heat waves are intermediate heat wave with 17 members and average maximum tem...
background: heat shock proteins (hsp) are highly conserved molecules with many immunological functions. they are highly immunogenic with important role in cancer immunotherapy and in vaccine development against infectious diseases. as adjuvant, hsp can augment the immunogenicity of weak antigens and can stimulate antigen presenting cells. although vaccines have been successful for many infectio...
An equation of state is presented for liquid iron based on published ultrasonic, thermal expansion, and enthalpy data at 1 bar and on pulse-heating and shock wave compression and sound speed data up to 10 Mbar. The equation of state parameters, centered at 1 bar and 1811 K (the normal melting point of iron), are density, P0 = 7019 kg/m 3 isentropic bulk modulus K so 109 7 GPa, and the firstand ...
We have developed an optical method for single-shot spatially resolved shock-wave peak-pressure measurements. A schlieren technique and streak photography were used to follow the propagation of the shock wave. The shock position r as a function of time was extracted from the streak images by digital image-processing techniques. The resulting r(t) curves were differentiated with respect to time ...
background several nonsurgical and surgical treatment modalities are available for patients with chronic coccydynia, with controversial results. extracorporeal shock wave therapy (ecswt) is effective in the treatment of many musculoskeletal disorders; however, it has not been tested for chronic coccydynia. objectives we performed the current study to determine the effects of ecswt on pain in pa...
Shock-driven hydrodynamic instabilities in a plasma usually lead to interfacial mixing and the generation of electromagnetic fields, which are nonequilibrium processes coupling kinetics with meso- macroscopic dynamics. The understanding modeling these physical very challenging tasks for single-fluid codes. This work presents new framework that incorporates both hydrodynamics simulate shock wave...
This paper examines the properties of a regularization of the Burgers equation in one and multiple dimensions using a filtered convective velocity, which we have dubbed as the convectively filtered Burgers (CFB) equation. A physical motivation behind the filtering technique is presented. An existence and uniqueness theorem for multiple dimensions and a general class of filters is proven. Multip...
Just as the harmonic map equation is a geometric analogue of the classical Laplace equation for harmonic functions, so the classical linear evolution PDEs, the heat, wave, and Schrödinger equations, have geometric “map” analogues: the harmonic map heat-flow, wave map, and Schrödinger map equations. These equations are nonlinear when the target space geometry is nontrivial. Quite remarkably, the...
high levels of regulated oncogen-alpha (gro-a) expression have been observed in the liver. gro-a stimulates proliferation of epithelial cells and induction of rolling and extravascular migration of neutrophils and mononuclear cells. given the above observations, this chemokine was chosen to be analyzed in freshly isolated and cultured hepatocytes. in this study, hepatocytes (2×106 cell/ml) were...
