Sun, 10 Nov 2024 00:00:00 +0000

The weft inserter is the core component of the piece shuttle loom, in which the weft inserter needs to hold the weft yarn and go through the process of launching, flying, braking and so on. In order to improve the acceleration performance of the weft inserter, according to the magnetization theory, it is proposed to increase the magnetic flux difference by adding permanent magnets to the weft inserter to increase the applied magnetic field force by comparing the position of the permanent magnet material in the weft inserter and analyzing the electromagnetic force on the weft inserter with the addition of the permanent magnet using Ansys Maxwell finite element software. The results show that the addition of a permanent magnet sheet at the end of the weft inserter increases the magnetic field gradient on both sides of the device and enhances the electromagnetic force.

Effect of reducing brewing yeast stress on the duration of extract fermentation

V.V. Gorshkov — Sun, 10 Nov 2024 00:00:00 +0000

The article studies the main stress factors affecting yeast cultures and develops recommendations for their reduction in order to increase the duration and efficiency of extract fermentation. High extractivity of the initial wort, high ethanol concentration, trace element content, presence of oxygen in the mixture, low temperatures and high pressure lead to various disturbances in yeast metabolism. To avoid stress, wort should be added to the stored seed yeast in a ratio of 1:5, followed by mixing the resulting suspension. When using the technology to reduce stress factors, the duration of the main fermentation is reduced by one day, which allows, while maintaining good quality of young beer (the deck does not close after rupture, the beer mirror is black, when visually assessed, the beer is transparent), to increase the production volume by 7% and the level of profitability of production by 5.2%. At the same time, reducing the period of the main fermentation does not affect the quality of young beer.

V.V. Gorshkov — Sun, 10 Nov 2024 00:00:00 +0000

The article studies the meat yield, tasting characteristics, nutritional and energy value of chicken meat of different origins and under different growing conditions. The highest yield after smoking is observed in broiler carcasses. Broiler meat, compared to the meat of laying hens and domestic chickens, is more juicy and tender. However, the meat of chickens raised in farm conditions had a richer taste and aroma. In terms of protein content, broiler chicken meat slightly exceeded that of chickens raised in farm conditions, and by 1.53% — meat of pullets of egg cross. The lowest energy value of 1 kg of meat was in the third group — 1855 kcal, which is 195-225 kcal less than in the first and second groups.

Assessment of beer quality when adding sugar flavor

V.V. Gorshkov — Sun, 10 Nov 2024 00:00:00 +0000

The article studies the organoleptic characteristics and physicochemical indicators of beer with the introduction of sugar color in the form of aqueous and alcohol solutions into boiled wort and at the final stage of fermentation. It was found that the best organoleptic indicators were characterized by beer of the experimental third group, in which caramel was introduced in the form of an aqueous solution into the boiled wort — 28 points. In the experimental samples of beer of groups 2 and 4, an increase in the volume fraction of alcohol was observed, which is associated with the introduction of an alcohol solution of color when adding it to the wort, while the stage of introduction did not significantly affect. Foam stability and carbon dioxide saturation were better in experimental samples with an aqueous solution of color in both options of introduction with an advantage of 7 sec. when adding to boiled wort. The lowest foam stability was observed in samples with alcohol solutions of colorant — at 38 and 27 seconds, compared to the control, which is probably explained by a decrease in hop substances with low surface tension.

V.V. Gorshkov — Sun, 10 Nov 2024 00:00:00 +0000

The article studies the effect of adding a vegetable component, a mixture of Provencal herbs, to semi-hard cheeses with subsequent smoking of the product. It has been established that enriching cheese with Provencal herbs has a positive effect on organoleptic indicators — the product acquires a spicy taste and aroma, and smoking the product allows to highlight the cheese taste, imparts a smoky aroma and a pleasant light yellow color. The use of Provencal herbs allows to estimate 10 points more by the sum of tasting indicators, and smoking allows to get the highest score among the experimental cheeses. The addition of Provencal herbs did not have a reliable effect on the physicochemical indicators of the cheese and its nutritional and energy value. However, smoking affected the change in the mass fraction of fat by 10.2%, the mass fraction of moisture and dry matter by 38.5%, the mass fraction of protein — 7.23%, active acidity — 0.17%, the difference in energy value was 9.6%.

M.R. Gallyamov — Sun, 10 Nov 2024 00:00:00 +0000

The topic under study is very relevant for countries with such vast territories as Russia. The usual practice of administrative division into separate regions and entities — namely, taking into account geographically determined boundaries — along rivers, along mountain ridges and other natural objects, in the future inevitably creates the need for joint careful and coordinated interaction for effective management of the territory. This article touches upon aspects of developing the tourism potential of the Southern Urals — as a territory with impressive natural and landscape diversity with relatively high transport and geographical accessibility. Its location at the conventional junction of Europe and Asia gives this area unique opportunities.

About the tasks of the economy in modern Russia (an attempt of philosophical reflection)

S.M. Zhuravleva — Sun, 10 Nov 2024 00:00:00 +0000

The economic and technological development of the regions of Russia is declared as a priority direction of domestic policy today, dominating the programs of social, cultural, educational and, generally, spiritual development of citizens. This choice of priorities in regional development should be determined by a clear and definite social goal and a holistic picture of the future of Russia, composed of clear anthropological, cultural and environmental perspectives. Today no one has such a clear picture of the future of Russia — neither officials, nor philosophers, nor even ordinary citizens, therefore vague formulations about the competitiveness of the country, prosperity and success of citizens are used in the development programs of the regions of Russia. The article explains the inadequacy of such formulations to the ontological nature of society and man, manifested in the unity of material and spiritual aspects. As a result, the irrationality of the modern economy as a whole is asserted and criteria for rational management are given.

Investments in the economy of the agro-industrial complex: trends and prospects

M.Yu. Lev — Sun, 10 Nov 2024 00:00:00 +0000

One of the tools for regulating prices for housing and communal services is regulated tariffs. This article examines their application in comparison with free market prices and tariffs for various types of goods and services. During the analysis of the forecast indicators for housing and communal services presented in the Forecast of the socio-economic development of the Russian Federation for the coming years, it was substantiated that despite the increase in the total area of residential premises, the quality of living conditions is declining. This is due to the growth of regulated tariffs, which are growing faster than free market prices for goods and services. In addition, changes in the regulatory framework that take into account «economically justified costs» lead to an increase in the cost of utilities and the income of enterprises providing these services. During the study, it was revealed that regulated tariffs have a significant impact on the solvency of the population and the provision of high-quality living conditions. The results obtained can be used by legislative and executive authorities in the formation of tariff and pricing policies aimed at ensuring the socio-economic security of society.

Issues of formation of regional budget revenue and budget security of the Far Eastern subjects of the Russian Federation in conditions of turbulence

S.N. Leonov — Sun, 10 Nov 2024 00:00:00 +0000

In the article, using general scientific research methods, a comparative analysis of the features of the formation of income of the consolidated budgets of the Far Eastern constituent entities of the Russian Federation is carried out, and an analysis of the state of budgetary security of the regions is given. It is shown that the degree of dependence of the budgets of the Far Eastern regions on federal transfers increased greatly during the pandemic and remained high during the period of sanctions restrictions; the desynchronization of the dynamics of own incomes and interbudgetary transfers in the Far Eastern regions increased. A deterioration in the transparency of interbudgetary relations in the macroregion during a turbulent period was revealed. A faster recovery has been shown in regions of the manufacturing industry, while in mining regions this process is slower. It is concluded that it is necessary to further improve the system of selective assistance to budgets in the form of subsidies, which will more adequately compensate for the revenues lost by regional budgets.
