TO THE THEORY OF STRENGTH OF DIESEL ENGINE EXHAUST GAS PURIFICATION OF SOOT PARTICLES
DescriptionThe problem of environmental protection from the contamination by toxic products, contained in the exhaust gases, is one of the most topical in the modern world. Nitrogen oxides and soot particles are the most toxic. Getting into the environment and the human body, they cause heavy chronic disease and significantly impair the quality of animal and plant products. The developed gas purification system SCR, the technology of plasma purification of exhaust gases have not found wide practical applications because of their high value. The study of papers dedicated to reducing exhaust gas toxicity shows that the use of combined means of purification, which usually include mechanical, thermal and catalytic methods of purification, is the most effective. Our work deals with the issue of purifying the diesel engine exhaust from fine particulate matter resulting in the combustion of fuel and oil motor partly. The article notes that the carbon is not magnetic, so the use of a magnetic field acting as an agent for the purification of exhaust gas from the carbon soot particles is impossible. The purification in a centrifugal field requires the creation of structurally complex centrifuges, so it is ineffective. We consider the possibility of purifying the exhaust gases from the soot particles in the electrostatic field. The device presents the collecting electrode, which is shaped as a cylinder, and an axial central electrode, which is mounted on an insulated spacer within the cylindrical body. The study deals with the physical and mathematical simulation of processes occurring in the proposed device of the purification of exhaust gases. The equality of the Coulomb force and the Stoks force determines the magnitude of the electrostatic field strength that is necessary for the purification of exhaust gas from the soot particles. We have identified the desired length of the collecting electrode

Description
Automated system-cognitive analysis (ASC-analysis) for images provides automatic identification of specific characteristics of the given images from the color of the pixels and image edges, the synthesis of generalized images of pictures (classes), identifying the most and the least specific image features for the class, determining values of features of images for their differentiation, deletion low-value characteristics (abstraction) from the model, problem solving for quantitative comparison of specific images with generalized images of classes and generalized images of the classes with each other, and objectives of the study of the simulated subject area by studying its model. The work discusses the new features of the ASC-analysis and its implementing intellectual system called "Eidos" for identifying features of images using their spectral analysis, formation of the generalized spectra of classes, the task of comparison of images of specific objects to classes and classes with each other in their spectra. For the first time, it became possible to form the generalized spectra of classes with weights of the colors according to their degree of specificity and unspecific features for classes, and it is not the intensity of the color in the spectrum, but the amount of information in the color on the linking the object with that color to the class. In fact, there is a question of generalization of spectral analysis by using intelligent cognitive technologies and information theory in the spectral analysis. First, everyone is talking about the fact that spectral lines contain information about which element or substance is included in the object, but no one bothered to count what exactly the amount of information is and then use it to determine the composition of the object pattern recognition methods based on the use of this information. Second, spectral analysis is traditionally used to determine the elemental and molecular composition of the object; we propose to use it not only for that, but also to identify any images. A numerical example has been given

Description
A selection of food additives for the enrichment of waffle products was made. Food additive "Powder from tubers of Jerusalem artichoke" is distinguished by a high content of inulin - 46.21%. Low-fat sunflower lecithin contains a significant amount of phospholipids (98.29%). The influence of the joint application of food additives "Powder from the tubers of Jerusalem artichoke" and nonfat sunflower lecithin on the technological properties of the wafer test was studied. It is established that the introduction of the food additive "Powder from the tubers of Jerusalem artichoke" together with defatted sunflower lecithin, instead of the traditional soybean, allows to reduce the viscosity of the wafer test. When introduced into wafer dough, the dosage of defatted sunflower lecithin can be reduced, compared to soybean, from 0.4 to 0.2% by weight of flour

A MODERN APPROACH TO POTATO PRODUCTION
DescriptionPotato has been and remains one of the five world's most important crops. For nearly two hundred years potato in Russia is the "second bread". This is one of the so-called social products. Over the past 20 - 25 years of potato farming in our country, there have been significant changes, both positive and negative. Today, potatoes are grown in different soil and climatic conditions in more than one hundred countries around the world, including the desert oasis and beyond the polar circle. Potato cultivation Center recently has moved to Asia. In our time, the leaders of potato production are China, Russia, India, the US and Ukraine. Over the past few decades the number of produced potatoes has increased by 41% and the area under potato planting only 9.5%. From the above data it is clear that the world potato economy in recent years has got significant changes, indicating that the timeliness and relevance of the material in this article is true

THE EFFECT OF PLANT FOOD ADDITIVES ON THE PROPERTIES OF WHEAT FLOUR AND DOUGH
DescriptionThe article presents data describing composition of macronutrients and food additives "Apple Powder" and food additive "Pumpkin Powder" obtained from secondary resources processing of apples and pumpkins with innovative technology that ensures their high antioxidant activity. Introduction of the studied food additives in wheat flour provides a boost of its antioxidant activity compared to the control (wheat flour without any additives). We have revealed that the introduction of the studied food additives in wheat flour provides a strengthening effect to the gluten flour, while dietary Supplement Powder called "Apple" has a strengthening effect on the gluten of wheat flour compared with a dietary Supplement called "Pumpkin Powder". We proved a positive impact of food additives on the gas-forming ability of wheat flour and water absorption capacity of dough; at he same time, with the same dosage of additives, water absorption capacity of dough with the introduction of additives of "Pumpkin Powder" is higher than this figure with the introduction of the additives of "Apple Powder", due to the higher content of pectin in the additive "Pumpkin Powder " compared with the additive "Apple Powder", having a high water-holding capacity. We have found that the dough with the introduction of the investigated supplements has the best rheological properties in comparison with control samples. The obtained results allow us to develop evidence-based formulation and technological modes of production of bakery products enriched with antioxidant properties, with the use of food additives called " Apple Powder" and "Pumpkin Powder"
