The article is devoted to the analysis of thermometric methods of control and diagnosis of the state of compression of the stator core of the turbogenerator (TG), which have found the greatest application. It is shown that ensuring effective and high-quality control of powerful electric machines, especially power plant generators, today is an integral part of ensuring the reliability and trouble-free operation of their work. As a result of the analysis, it is shown that ensuring high reliability of operation of the generating equipment is practically impossible without their equipping with modern means of control capable to work in real-time.

The quality of products represents one of the key aims of any modern organized production. In the production practice, it is essential to establish the optimal relationship between quality, production economy and delivery deadlines. Furniture quality is evaluated by three levels and they are: basic quality, high quality and especially high quality. The results presented in this paper are based on the sample measurements of chairs and tables during 2007 and 2008 at the Institute for Furniture Quality Control.

Abstract. The SeaSWIR dataset consists of 137 ASD (Analytical Spectral Devices, Inc.) marine reflectances, 137 Total Suspended Matter (TSM) measurements and 97 turbidity measurements gathered at three turbid estuarine sites (Gironde, La Plata, Scheldt). The dataset is valuable because of the high quality measurements of the marine reflectance in the Short Wave InfraRed I region (SWIR-I: 1000–1200 nm) and SWIR-II (1200–1300 nm) and because of the wide range of TSM concentrations from 48 mg L−1 up to 1400 mg L−1. The ASD measurements were gathered using a detailed measurement protocol and were subjected to a strict quality control. The SeaSWIR marine reflectance is characterized by low reflectance at short wavelengths (

The article under discussion considers methods of quality control of turkey meat products. The author believes that the quality control of food raw materials and food products is a significant stage in the production of food products. It is important to organize research aimed at improving the quality and safety of turkey meat products, using accurate, rapid, and highly effective methods of infrared spectroscopy and chromato-mass spectrometry to determine its chemical composition to develop methods to determine the correctness of HS codes.

This study purpose was to optimize the production technology of encapsulated functional detoxicants based on combined dietary fibers (DF) obtained from beet pulp according to the developed technology. Production technology optimization for functional encapsulated food products was performed using mathematical programming methods based on Statistica v.10 and MathСAD v.15 software environments. An optimal technological production mode for encapsulated food products with high quality indicators, having an increased detoxification ability in relation to heavy metal ions, including combined DF, obtained from beet pulp.

При производстве качественной пищевой продукции особое внимание необходимо уделять ее упаковыванию и хранению. Витаминно-минеральные концентраты, используемые для приготовления пищевых продуктов и получения качественной безопасной продукции животноводства, содержат комплекс лабильных биологически активных веществ, для сохранности которых необходимо минимизировать окислительные процессы. Это обусловливает повышенные требования к упаковке таких продуктов. С целью выбора упаковочного материала и способа упаковки витаминно-минерального концентрата проведен тематический обзор публикаций отечественных и зарубежных ученых. Рассмотрены тенденции в области применения упаковочных материалов, указаны преимущества и недостатки биополимеров. На основе проведенного анализа установлено, что для упаковывания витаминно-минерального концентрата целесообразно в качестве материала упаковки использовать полимерные пленки, обладающие высокой свето- и газонепроницаемостью, позволяющей снизить скорость протекания окислительных процессов и, следовательно, сократить потери содержащихся в продукте лабильных биологически активных веществ. В качестве способа упаковки можно рекомендовать применять вакуумирование, обеспечивающее отсутствие кислорода воздуха в упаковке. When producing high-quality food products, special attention should be paid to their packaging and storage. Vitamin and mineral concentrates used for food preparation and production of high-quality safe livestock products contain a complex of labile biologically active substances, for the safety of which it is necessary to minimize oxidative processes. This leads to increased requirements for the packaging of such products. In order to select the material and method of packaging of vitamin and mineral concentrates, a thematic review of publications of domestic and foreign scientists was conducted. Trends in the use of packaging materials are considered, advantages and disadvantages of biopolymers are indicated. It was found that for packaging vitamin and mineral concentrate, polymer pellicle with high light and gas tightness, which allows reducing the rate of oxidative processes and, consequently, reducing the loss of labile biologically active substances contained in the product, should be used as a packaging material. Vacuuming, which ensures the absence of oxygen in the air in the package, can be recommended as a method of packaging.
