peri-implantitis is one of the most common reasons for implant failure. decontamination of infected implant surfaces can be achieved effectively by laser irradiation; although the associated thermal rise may cause irreversible bone damage and lead to implant loss. temperature increments of over 10ºc during laser application may suffice for irreversible bone damage.the purpose of this study was ...

We investigate the structure of the phase separation line between the pure phases in the two-dimensional lsing model, the liquid and vapor phase in lattice gas language, at low temperatures. The fluctuations in the location of this line are known to diverge in the thermodynamic limit, something which is also believed to happen to the continuum liquid-vapor interface in three dimensions (in the ...

The three-dimensional, three-state Potts model is studied as a paradigm for high temperature quantum chromodynamics. In a high statistics numerical simulation using a Swendson-Wang algorithm, we study cubic lattices of dimension as large as 643 and measure correlation functions on long lattices of dimension 202 × 120 and 302 × 120. These correlations are controlled by the spectrum of the transf...

In order to understand a heat transfer phenomenon, it is sometimes very important to know the change in heat flux and temperature with time or the distribution of the heat flux and temperature on the surface of a heating block. Furthermore, with the development of computational thermal-fluid dynamics, experimental data that are of the CFD level, both spatially and temporally, are needed to vali...

SIR,-We refer to the article by Dr. I. K. Crombie (1981) on the distribution of malignant melanoma on the body surface. Unfortunately, the author's calculations of the proportional distribution by site of total body melanocytes may be erroneous. In his Table III, the proportions of body surface area at different sites appear to have been transposed, such that the surface area of the upper limb ...

With respect to the limitations of fossil energy resources, different types of electric vehicles (EVs) are developed as suitable alternatives. Lithium-ion (Li-ion) battery cells play an extremely important role in EVs due to their unique features. But they need a thermal management system (TMS) to maintain their surface temperature uniformity and avoid them from thermal runaways. In the current...

In this paper a transient free convection flow around a sphere with variable surface temperature and embedded in a porous medium has been considered. The temperature of the sphere is suddenly raised and subsequently maintained at values that varies with position on surface. The method of asymptotic expansions is applied for small Rayleigh numbers and then a finite-difference scheme is used to s...
