Low-temperature nitriding of steel or iron can produce an expanded austenite phase,which is a solid solution of a large amount of nitrogen dissolved interstitially in fcc *** is characteristic that the nitogen depth profiles in expanded austenite exhibit plateau-type *** behavior cannot be considered with a standard analytic solution for diffusion in a semi-infinite solid and a new approach is *** formulate a model of interdiffusion in viscoelastic solid(Maxwellmodel)during the nitriding *** combines themass conservation and Vegard’s rule with the Darken bi-velocity *** model is formulated in any dimension,i.e.,a mixture is included in R^(n),n=1,2,*** the system in one dimension,n=1,we transform a differential-algebraic system of 5 equations to a differential system of 2 equations only,which is better to study numerically and *** modification allows the formulation of effective mixed-type boundary *** resulting nonlinear strongly coupled parabolic-elliptic differential initial-boundary Stefan type problem is solved numerically and a series of simulations is made.

Poultry meat production steadily increases and its by-products including legs or skins may be further utilized to prepare gelatine,generally by using alkali or acid *** they are toxic,different methods are desirable,*** proteolytic *** enzymes is beneficial as they shorten processing time and reduce the required water *** conditions(the enzyme amount during the pre-treatment,first and second extraction temperature and time)of the process may influence gelatine quality and its *** this study,gelatines were prepared from chicken skin at different conditions in the series of combined factorial design of *** significance of the influence of the conditions on the quality(gel strength,viscosity,melting and gelling point)and yield of chicken skin gelatine(CSG)was *** highest yield(31.5%)was obtained at the conditions of the enzyme amount of 0.8%,first extraction temperature 80℃ and time 30 min,second extraction temperature 90℃ and time 60 ***,the highest CSG quality of gel strength(190 Bloom),viscosity(4.06 mPas),melting point(38.3℃)and gelling point(20.5℃)was obtained at the conditions of 0.2%/50℃/30 min in the first extraction.
