Description
The article studies the influence of polymeric in the form of formers and growth regulators on the growth and development of rice plants when grown in saline conditions. We controlled the effect of salinity on grows regulators and vigor, seed germination, root and shoot weight, the content of photosynthetic pigments parameters, induction curves of delayed fluorescence, the indicators of structure of harvest, grain yield. It was found, that pre-sowing seed soaking in solutions of polymer grows regulators has a stimulating effect on the growth and development of rice plants in the early stages: we significantly increased germination and emergence, dry weight of root and shoot compared to control. At different stages of ontogeny rice, the absolute content of pigments in the leaves and the relationship between the individual variants change. The absolute content of pigments in leaves and their relationship between experiences at different stages of ontogeny change. In the period of intensive vegetative growth from seedling stage the content of total chlorophyll is maximum, and by the end of the growing season it decreases. It can be assumed that the salinity of the substrate significantly reduces the productivity of photosynthesis in young plants, possibly due to imbalance of ions in the cell, the older it gets – the weaker the phenomenon is and even becomes reversed. The second maximum IR ZF increases during the growing season from germination to flowering, then decreases to the beginning of ripening in all embodiments. The same dynamics is characteristic of the magnitude of the proton gradient in the membranes of chloroplasts tylakoids. Salt protection effect of growth regulators on grain yield is significant on both backgrounds of mineral nutrition

PHENOMENOLOGICAL APPROACH TO THE DESCRIPTION OF TRANSPORT PROCESSES IN LOOSIBILE MATERIALS
Description
A mathematical description of the potentials of mass-transfer of hygroscopic materials is possible on the basis of analytical expressions describing sorption and desorption isotherms. Because of the complex nature of the interaction of colloidal capillary-porous materials with moisture, determined by the action other than sorption forces (physical sorption, absorption, chemisorption), capillary condensation forces and osmotic forces, which for different materials are specific and quantitatively different, to date There is no single universal dependence for the analytical description of isotherms of sorption and desorption. Accordingly, there is a wide variety of analytical expressions for the description of isotherms of sorption and desorption. There are many different methods of analytical description of the sorption properties of colloidal capillary-porous materials. All known methods can be divided into two groups: the first should include analytical expressions derived theoretically on the basis of various hypotheses and assumptions, while the second - purely empirical based on the expansion or change in the forms of models of the first group. A large number of equations of equilibrium isotherms are mathematically equivalent. Thus, the method of determining the transport potential based on position allows us to take as a basis for calculation the experimental data on the hygroscopic properties of certain materials and to use the phenomenological approach for the engineering calculation of complex technical devices

FEATURES OF MODELING OF TECHNOLOGICAL OPERATIONS OF AGRICULTURAL RAW MATERIALS PROCESSING
Description
The ways of improving the work of food enterprises during processing of agricultural raw materials on the basis of a system analysis of the durations of technological operations are considered. The basic mathematical models of technological processes have been analyzed and the possibility of using unified technological operations to predict the time of completion of work has been shown for processing various pairs of raw materials. It is established that the construction of mathematical models of technological processes of processing of agricultural raw materials should be based on using the potential of transfer of the target component between isopotential surfaces. This allows not only to unify the created models of technological processes, but also to significantly increase their extrapolating ability to estimate the durations of technological operations
