The article presents data on the study of the effect of varietal characteristics of potatoes on the formation of yield and quality of tubers. The aim of the work was to identify the best varieties of potatoes for cultivation in Nizhny Novgorod region. For conducting research, the following methods were used: experiments at cultivation, storage, use of potatoes, laboratory studies, tasting evaluation, and ranking. The effect of tuber damage by common scab and rhizoctoniosis on the safety of potato tubers was revealed. It had been established that all varieties of potatoes in conditions of highly cultivated sod-podzolic soils form a high yield of tubers. The maximum yield provides cultivation varieties Crystel and Sandrine. Crystel and Sandrine Varieties were characterized by a maximum yield of marketable tubers and weight per tuber. They also had the high starch content in tubers, the maximum tasting and overall assessment of tubers. It was noted that tubers of all varieties were slightly affected by common scab and rhizoctoniosis, which had a positive effect on their ability to work. To a lesser extent, these diseases affected the tubers of the varieties Crystel, Sandrine, and Serafina. The quality of these varieties was at the level of the standard.

The article discusses the problems that arise before the specialists of engineering and technical services of agro-industrial enterprises when storing agricultural equipment, and the leading domestic and foreign developments in the field of corrosion protection. Deficiencies in modern conservation technologies are considered and recommendations on how to solve them are given.

Качество образования является ключевым понятием подготовки специалистов любой отрасли, в том числе и медицины, что обусловлено прямой взаимосвязью с конкурентоспособностью выпускников вузов. Очевидно, по этой причине проблеме разработки понятийного аппарата, разработки систем оценки качества образования и практической реализации посвящено множество исследований. Однако, к настоящему времени нет единого понимания «качества образования», существующие системы оценки качества ориентированы на соответствие государственным образовательным стандартам. Для решения проблем качества образования мы посчитали целесообразным использовать возможность создания динамической модели системы качества образования внутри вуза, основанной на системном анализе. Данный подход позволил, во-первых, рассмотреть качество образования как систему, состоящую из входных и выходных данных, подсистем, процессов. Во-вторых, выявить причинно-следственные связи между факторами, влияющими на качество образования и, в-третьих, построить ретроспективную и прогностические модели динамики качества медицинского образования. Установлено, что качество медицинского образования является функцией зависимости множества переменных, наиболее значимое влияние на качество образования оказывают показатели остепенённости профессорско-преподавательского состава, уровень их удовлетворенности социальной поддержкой работодателя. Реализовать разработанную динамическую модель системы качества образования в вузе авторы предлагают в виде ситуационного центра, основанного на объективном анализе данных, визуальном представлении полученных результатов.

Introduction. A promising direction for granulation of combined secondary raw materials of animal and vegetable origin is high-temperature molding of granules under the influence of an electromagnetic field of super highfrequency (SHF-EMF), which improves the microbiological parameters of protein feed.Results. Microwave granulators of multicomponent raw materials containing different design versions of resonators have been developed— for example, toroidal, cylindrical and ellipsoidal resonators. The electrodynamic parameters of these resonators are determined and the technical characteristics of the granulators are described. The required specific heat for the processing of secondary fat-containing raw materials has been calculated. With a granulator capacity of 200 kg/h and a specific power of the microwave generator of 1.4–2 W/g, the duration of exposure to the raw material weighing 0.8–1 kg in the resonator chamber should be 10–12 s. This ensures the minimum specific energy costs of 0.06 kW·h/kg.

The article describes the installation of microwave drying UMS-2-10, its use in agricultural enterprises. Installation of combined drying (microwave and convective heating). The installation was developed by the research and production Association "Gamma" in Nizhny Novgorod. The principle of operation is based on the use of microwave energy in combination with the circulation of "warm" air. It is established that when choosing a drying unit for the food industry, it is necessary to keep in mind that the scientifically justified choice of the design of the dryer intended for drying specific types of plant substrates containing biologically active substances is more dependent on the structural properties and biological composition of the plant raw materials used in production. Drying plant UMS-2-10 installation provides for the use of microwave, convective and combined methods of heating the feedstock; characterized by small size and ease of operation; has optimal performance, focused on the orders of commercial enterprises, and not on the formation of large batches of finished products, the implementation of which may be in doubt; characterized by high maintainability, low cost and tariffs for delivery, and installation of the dryer.
