The article considers a model of plastic deformation polymer material in the inter-roll space processing equipment under conditions compression and shear, based on which it is established that all-round pressure created by working bodies causes only viscoelastic deformation, therefore compaction process its destruction does not occur. Numerical modeling waste between rolls Relo profile made pos...

An important application of simulating wave propagation in bone is the early detection osteoporosis. During course this disease cortical reduced and replaced by marrow, weakening increasing likelihood fractures [1]. Commonly, modeling problem to only mechanical effects. Recent research includes electrical magnetic effects as well [2-4]. In our previous contributions we introduced a two-phase ma...

As a part of this study, mathematical model based on two-compartment pharmacokinetic system with general fractional derivatives was developed. Its aim to describe the release BisGMA and TEGDMA monomers from composite core resin over three time periods. For purpose, five Clearfil Photo Core samples were prepared elution measured using high performance liquid chromatography at 1, 7 28 days post-i...

It is increasingly necessary to promote means of production that are less polluting and harmful the environment following UN 2030 agenda for sustainable development. Using natural cellular materials in structural applications can be essential enabling a future this direction. Cork material with an excellent energy absorption capacity. Its use engineering products has grown over time, so predict...

This paper studied the coupling model of material flow and energy flow in the production process of lead smelting enterprises, and established the mathematical model for material flow and energy flow to resolve optimization problems. From the point of energy flow, the paper analyzed three kinds of energy flow changes which have an effect on the enterprise products. Through calculation and analy...
