INTRODUCTION Malignant melanomas account for 5% of all skin cancers and usually have a fatal clinical course. Additionally, the incidence of melanoma increases more rapidly than in any other cancer, and this has been attributed to the development of highly sensitive diagnostic techniques, mainly dermoscopy, which allows for early diagnosis. The phenotypic manifestations of gene/environment inte...

The effect of curvature on the surface tension of droplets and bubbles in both single and multicomponent systems is modeled using the basic equations from classical thermodynamics. The three expressions used in our work are the Gibbs adsorption equation for multicomponent systems, the relation between the surface tension at the surface of tension and the distance parameter , and the Macleod–Sug...

A novel multicomponent synthesis of ketene dithioacetal rhodanines has been reported by reactions of primary amine, carbon disulfide, ethyl chloroacetate, and alkyl halide in DMF. The catalytic effects of different bases have been investigated and potassium carbonate can efficiently catalyze the reaction in moderate to good yields at room temperature. 2013 Elsevier Ltd.

The existing measuremenJs of the viscosity of gaseous systems can be extended if use is made of statistical mechanics. In this work, we confine ourselves to the measurements of the viscosity of multicomponent mixtures of low-density gases. The method is applied to one sample of natural gas.

A size-segregated aerosol dynamics model UHMA (University of Helsinki Multicompo-nent Aerosol model) was developed for studies of multicomponent tropospheric aerosol particles. The model includes major aerosol microphysical processes in the atmosphere with a focus on new particle formation and growth; thus it incorporates particle 5 coagulation and multicomponent condensation, applying a revise...

Nonaqueous phase liquid (NAPL) contaminants that are chemical mixtures often contain compounds that are solids in their pure states. In the environment, weathering processes cause shifts in multicomponent NAPL composition, thereby enriching the NAPL in the less soluble compounds which may result in their eventual solidification. In this paper, we review the thermodynamic theory governing solid–...

The derivation of the multicomponent diffusion law is revisited. Following Furry Am. J. Phys. 16, 63 1948 , Williams Am. J. Phys. 26, 467 1958 ; Combustion Theory, 2nd ed. Benjamin/ Cummings , Menlo Park, CA,1985 heuristically rederived the classical kinetic theory results using macroscopic equations, and pointed out that the dynamics of the mixture fluid had been assumed inviscid. This paper g...
