Determination Of Toxicity Of Chopped Meat-based Semi-products In Vivo

At solving the problem of protein deficiency, the great role of the raw material for its production is played by leguminous cultures such as peas, haricot beans, lupine, forage beans, lentil, chick-peas, peavine and other. The chemical composition and food value of proteins of these cultures are most close to animal proteins – of meat, fish and also milk. Among the essential quantity of vegetable raw material that contains protein (33 - 50 %), the special place is occupied by lupine, characterized as an important reserve of high-quality protein substances at the World congress in 1991 in the USA [1].There were elaborated certain recipes of meat chopped semi-products, based on beef that contains 5 %, 10 %, 15 % of lupine flour and 0,5 % of elecampane root powder.There were carried out the studies on the determination of toxicity of functional raw material and cutlets with 10 % content of lupine flour and 0,5 % of elecampane on white mice organisms. There were used methods, based on toxic substances extraction from forages and peeled gains under condition of the intra-stomach administration and cutlets feed during 10 days. Blood was taken for hematological studies in mice, fed by functional cutlets.It was proved, that these products have no toxic influence on organisms. At the pathoanatomical dissection, any macroscopic changes in tissues were not revealed, blood hematological results are within norm.The best sample № 2 with 10 % content of lupine flour and 0,5 % of elecampane was determined by the gustatory method.It was determined, that functional meat chopped semi-product may be included in the ration for the sound, treating-prophylactic nutrition

Research of thermoelastic state of the contacting thermosensitive half-spaces with heat release on the edge touch

Побудовано розв’язок квазістатичної задачі термопружності для двох контактуючих термочутливих півпросторів з миттєвими або постійними тепловиділеннями на межі дотику та досліджено їх термопружний стан.Modern scientific-technological development in determination of the stress-strain state of structural elements imposes increased demands to their mathematical models in order to represent more completely real physical processes. This, in turn, anticipates accounting of such important factors as thermosensitivity of materials, complex heat exchange, presence of internal heat sources, power loads, contact interaction, etc. When neglecting mechanical energy transformation into heat energy we arrive at the solution of the quasi-static uncoupled thermoelasticity problem, which is divided into separate problems: determination of the temperature field of the body and determination of its thermoelastic state caused by this field and other possible power factors. Complexity of such models lies in the necessity to solve nonlinear boundary- value problems of mathematical physics and boundary-value problems for the systems of differential equations with variable coefficients. Beside numerical methods, analytical-numerical approaches are widely used to solve such class of problems. They make it possible to verify the reliability of purely numerical solutions and to widen the possibilities of engineering practice as to choice of efficient and available means of solution actual problems. One of such approach, based on utilization of the linearizing parameters method, which was widely approved on non-stationary heat conduction problems for thermosensitive bodies of simple geometric shape under complex heat exchange with the surroundings, was approved as to solution of the heat conduction problems for contacting thermosensitive bodies for heat sources acting on the contact boundary. The solution of quasi-static thermoelasticity problem for two contacting half-spaces, made of zirconium oxide and titanium alloy with instant or constant heat release on the contact boundary was constructed. Their thermoelastic state was studied
