Increasing Production Volumes Research Articles

Enhancement of Soybean Meal Alters Gut Microbiome and Influences Behavior of Farmed Atlantic Salmon (Salmo salar).

Atlantic salmon (Salmo salar) is one of the worlds most domesticated fish. As production volumes increase, access to high quality and sustainable protein sources for formulated feeds of this carnivorous fish is required. Soybean meal (SBM) and soy-derived proteins are the dominant protein sources in commercial aquafeeds due to their low-cost, availability and favorable amino acid profile. However, for Atlantic salmon, the inclusion of soybean meal (SBM), and soy protein concentrate (SPC) in certain combinations can impact gut health, which has consequences for immunity and welfare, limiting the use of soy products in salmonid feeds. This study sought to address this challenge by evaluating two gut health-targeted enhancements of SBM for inclusion in freshwater phase salmon diets: enzyme pre-treatment (ETS), and addition of fructose oligosaccharide (USP). These were compared with untreated soybean meal (US) and fish meal (FM). This study took a multi-disciplinary approach, investigating the effect on growth performance, gut microbiome, and behaviors relevant to welfare in aquaculture. This study suggests that both enhancements of SBM provide benefits for growth performance compared with conventional SBM. Both SBM treatments altered fish gut microbiomes and in the case of ETS, increased the presence of the lactic acid bacteria Enterococcus. For the first time, the effects of marine protein sources and plant protein sources on the coping style of salmon were demonstrated. Fish fed SBM showed a tendency for more reactive behavior compared with those fed the FM-based control. All fish had a similar low response to elicited stress, although ETS-fed fish responded more actively than US-fed fish for a single swimming measure. Furthermore, SBM-fed fish displayed lower repeatability of behavior, which may indicate diminished welfare for intensively farmed fish. The implications of these findings for commercial salmonid aquaculture are discussed.

Evolution of households and private farms of the population in Russia

Personal subsidiary farms are the most important sector of the agrarian economy, a factor of survival and ensuring food security for most people, providing more than half of the food in the country. The purpose of the research was to analyze the evolution of the formation of households and small farms of the population in Russia. The evolutionary and chronological development and formation of Russian household farmsteads and private farms of the population have been presented in the article. The main stages of the development of households of the population as the most important socio-economic institution and contribution to the agricultural sector of the economy are substantiated. We believe that the eff ective and successful development of private farms will signifi cantly reduce the time frame for the implementation of the food problem and the independence of the country. The income level of the rural population is 3 times lower than the national average. An increase in production volumes in subsidiary farms will help to reduce this gap and solve the country’s food security. Eff ective state support for smallscale farming and personal subsidiary farms is the most important basis for the eff ective development of agricultural production and food security of the country. The system of state support should be aimed at the development of livestock industries in private farms. In this regard, fi nancial resources are needed for the construction of livestock facilities and their equipment, feed and young animals are needed. Without the effective assistance of the state and the provision of funds, the development and diversification of private farms is not possible, farmers have nowhere to take or borrow them, and feed and young farm animals can be obtained in the public economy on mutually beneficial and agreed terms of cooperation.

Innovations in the agro-industrial complex of the Aktobe region of the Republic of Kazakhstan: an effective mechanism for solving the food issue

Purpose – the article discusses the current aspects of the development of agroindustrial complex on the example of the Aktobe region, presents recommendations that contribute to the solution of these issues. Research methods – abstract-logical, statistical, observation, scientific abstraction. Factor analysis, grouping method, tabular and graphical methods of data visualization were used as statistical tools. Results – studying the foreign practice of modernizing agricultural sector in order to ensure food security, the authors note that the main criteria should include the system of state and local self-government, legislative framework, fiscal and monetary regulation, mechanism of subsidizing and lending, investment, innovation policy. The main indi cators of agricultural production in the region for 2017-2021 are analyzed. It is proved that at present it is necessary to restore this strategically important sector of economy on a qualitatively new technical and technological basis that meets modern trends. Agrarian science of Kazakhstan has developed a fairly large number of innovations, the implementation of which in the agroindustrial complex would raise it to a high level. However, the degree of use of innovations by commodity producers remains very low. One of the problems of the low activity of innovative processes is the lack of motivation in the development of innovations by agricultural producers. Conclusions – innovative development involves the transition to resource-saving technologies that contribute not only to increasing production volumes, but also saving resources, as well as achieving the required level of food security. This complex task requires the creation of appropriate conditions: appropriate infrastructure for innovation activity, a set of material, technical, legislative means for information, marketing, financial, and personnel services for business entities.

Факторы структурной трансформации экономики Ленинградской области в новых условиях

The article is focused on the problems of structural restructuring of economic activity of the Leningrad Oblast as a result of sanctions pressure and restrictions on international interactions that emerged in 2022–2023. The paper analyzes the following factors that can affect the structure of the region’s economy: transformation of logistics and transportation capabilities; termination or suspension of a number of foreign enterprises; difficul-ties with the application and supply of foreign technological lines, innovation and information technologies; restrictions on exports; increased production volumes in the defense industry sector; increased state support of certain industries, primarily small and medium-sized businesses. Conclusion is made that changes in the struc-ture of the economy are taking place in the region, but, most likely, they will be of a short-term nature, since Leningrad enterprises have a significant potential for flexibility and adaptability to the existing conditions, which is supported by the substantial support of the regional authorities.

The Convergence of Factors That Affect the Dairy Product Market: A Comparative Analysis of European Union Countries

The European Union is a large producer of milk and dairy products. It is also a significant market for the consumption of dairy products, which is characterised by effective demand, and it significantly influences the markets of other food products. The main milk producers in the EU are Germany, France, Poland, the Netherlands, Italy and Spain. Intensive migration has contributed to additional demand for food products, in particular, dairy products. This provided the basis for the construction and calculation of a dynamic model of dairy production, the export of dairy products, and the coexistence with the existing population as the main consumers in the EU–27 countries and Great Britain between 2004 and 2020.
 An additional research value is that based on the presentation of the analysis and modeling, the relationship between the growth in the demand for dairy products and the growth in the population is established. The reason for the large population in the countries of Central and Eastern Europe is intensive migration flows, which increase the demand for dairy products. The increase in volumes reduces the cost price, which contributes to the export of dairy products, and also contributes to the increase in the volume of production of dairy products. The resulting models made it possible to analyse the influence of population growth on the increase in production volume. At the same time, the dependence and influence of the export of dairy products on the increase in the volume of production of dairy products in the EU–27 and Great Britain countries is investigated.
 The results of the mathematical modelling indicate unique opportunities to develop the dairy sector of individual EU–27 countries, i.e., the Czech Republic, the Netherlands, and Poland. These countries have a rational ratio of the influence of the population growth factor on the increase in the volume of dairy production and the optimal influence of the export of dairy products on the increase in the volume of dairy production.

Soybean testa spectral study

The increasing production volumes of soy foods require new express methods for testing soybeans during processing and presowing. This study assessed the efficiency of spectral pre-sowing assessment methods using Vilana soybeans.
 The research featured soybeans of the Vilana cultivar. The control sample consisted of untreated whole soybeans while the test samples included soybeans pretreated with various modifiers. The methods involved spectrofluorimetry and IR-Fourier spectrometry.
 A wide emission band at 400–550 nm corresponded to the fluorescence of the soybean testa. The band at 560–610 nm indicated the presence of such modifiers as Imidor insecticide and Deposit fungicide. The luminescence spectrum of the untreated soybean testa was maximal at 441 nm. The luminescence spectrum of the treated soybean samples was maximal at 446.5 and 585 nm when the excitation wavelength was 362 nm. The fluorescence was studied both spectrally and kinetically to establish the maximal luminescence time and the typical vibration frequencies.
 The spectral studies of Vilana soybeans before and after treatment revealed which modifiers were adsorbed on the palisade epidermis and defined the type of interaction between the modifier and the soybean. The spectrofluorimetry and IR spectroscopy proved able to provide a reliable qualitative and quantitative analysis of Vilana soybean surface.

IMPROVEMENT OF THE TECHNOLOGICAL PROCESS ACCOUNTING OF SALARY AT THE INDUSTRIAL ENTERPRIS

The article regarding the working conditions of an industrial enterprise describes approaches to rational differentiation of wages taking into account the following: qualifications of jobs and employees; quantitative results of labor; working conditions, which means difficult and special sanitary and hygienic conditions of work processes; the role of an employee (profession) in production, which determines the degree of his influence on the results of collective work on manufacturing of the main production. It is substantiated that increasing production volumes and increasing profit on investments requires constant improvement of wage accounting in case of changes in wage payment systems and wide use of modern computing equipment. It was concluded, that for small-scale production it is advisable to display the corresponding rate of payment together with the performance of various non-repetitive works or operations in the orders. For the brigade form of work, it is advisable to provide the necessary data for calculating earnings and their distribution among the members of the brigade on the reverse page of the order, taking into account the labor participation rate of each member of the brigade, which will contribute to the efficient operation of enterprises in conditions of intense competition. Rationalization of various allowances and payments additional to official salaries, as well as bonuses and rewards, which are systematic, in case of systematic reduction of total costs was performed. The implementation of the electronic form of sick leaves and the electronic register of sick leaves in the employer’s personal account causes the accounting staff to rationalize the “ready for payment” operation. The organization of the technological process of accounting for both sick leaves at the expense of the social insurance fund and additional vacations for liquidators of the consequences of the accident at the Chernobyl Nuclear Power Plant is detailed. The mechanism for regulating inter-job salaries and intra-production tariffs, taking into account the qualifications of an employee, his education, the degree of responsibility for the work performed, initiative, length of service at the given enterprise, and the results of qualification certification of workers was improved. A rational report form has been developed to avoid discrepancies, numerous errors and inaccuracies in the process of accruing and transferring of preferential pensions at the expense of the funds of enterprises and organizations which are paid and delivered by employees of the Pension Fund.

Use of existing gas infrastructure in European hydrogen economy

The rapidly increasing production volume of clean hydrogen creates challenges for transport infrastructure. This study improves understanding of hydrogen transport options in Europe and provides more detailed analysis on the prospects for hydrogen transport in Finland. Previous studies and ongoing pipeline projects were reviewed to identify potential and barriers to hydrogen transport. A fatigue life assessment tool was built because material challenges have been one of the main concerns of hydrogen transportation. Many European countries aim at utilizing existing gas infrastructure for hydrogen. Conducted studies and pilot facilities have provided promising results. Hydrogen reduces the fatigue life of the pipeline, but existing pipelines can be used for hydrogen if pressure variation is maintained at a reasonable level and the maximum operation pressure is limited. Moreover, the use of existing pipelines can reduce hydrogen transport costs, but the suitability of every pipeline for hydrogen must be analyzed, and several issues such as leakage, leakage detection, effects of hydrogen on pipeline assets and end users, corrosion, maintenance, and metering of gas flow must be considered. The development of hydrogen transport will vary within countries depending on the structure of the existing gas infrastructure, and on the future hydrogen use profile.

Investigating the differences in human behavior between conventional machining and CNC machining for future workforce development: A case study

Due to the high efficiency and consistent product quality, CNC machining has gained a dominant role in the modern machining industry. However, conventional machining still has its significance for certain production settings, e.g. prototyping, and machining workforce preparation. CNC and conventional machining require particular skills and knowledge, which can be unique to specific types of machine tools or overlap to a certain extent. With increasing production volume demands and an aging workforce, a need for efficient quantification, preservation and transfer of said skillsets arises to ensure effective preparation of future professionals and the undisrupted operation of the manufacturing industry. Moreover, the observed shift towards human-centered manufacturing systems in the Industry 4.0 necessitates obtaining an in-depth understanding of human roles in machining. The following paper proposes a novel research approach based on collection and analysis of eye-tracking and video data supplemented by verbal interviews, surveys and self-assessment. A conducted case study spans the entirety of the machining process, from part evaluation, cutting strategy determination, machining operations, to process re-evaluation and optimization. The results show that far greater variability in cutting strategy in terms of operation order, number of operations and used production tooling between consecutive production runs can be observed for conventional machining, with little variation in those terms noted for CNC-based production. Overall, the collected data has allowed to gain an insight into the machinist's decision-making processes and the rationale for observed cutting strategy changes, allowing for potential future application of the proposed research method in improving the machining training and potentially aiding process design by applying the outcomes of studies performed with the use of presented research method to expert systems and future CAM/CAE software solutions.

Silicon from sand is a promising technology for producing silicon of semiconductor quality

An analysis of the methods for obtaining silicon of semiconductor quality determined the relevance of the issues of compliance of modern technologies with environmental requirements of today, as well as the possibilities of raw materials and energy supply for a potential increase in production volumes. The development of production requires a search for compromises between the needs of society and the consequences expressed in the environmental impact on nature, the growth in the consumption of raw materials and energy. The proposal to use quartz sand instead of quartzite is promising due to the solution of the problems of raw material supply for the production of silicon of semiconductor quality for many years to come. The technology of chlorination of quartz sands proposed for implementation has been tested in industrial conditions and, in addition to the problems of raw material supply, to a large extent solves the problems of environmental and energy supply.Within the framework of the set environmental task, the problems of decarbonization of production are first of all solved by eliminating the energy-consuming high-temperature process of carbothermal reduction of silicon. The proposed technological solution provides a compromise between environmental friendliness and energy efficiency by involving silicon-containing materials, technogenic wastes, as “energy donors” in physical and chemical processes. Chlorination of the prepared raw materials is carried out in the solid phase, which is an energy-efficient solution, as it eliminates the cost of energy to compensate for the latent energy of melting. The initial preparation of raw materials involves the procedure of mechanoactivation - energy-efficient activation of the raw material by destroying intercrystalline bonds. The use of “energy donors” in blending ensures that the chlorination process is carried out in the autothermal mode, reducing the specific consumption of chlorine for the process. The problems of high energy intensity in the production of silicon of semiconductor quality are also solved by adjusting the technological scheme with the exclusion of energy-consuming low-temperature processes.The implementation of the proposed technological solutions is focused on the maximum use of known technological equipment, which minimizes the costs of design and production development of the technology. Based on the practical data obtained, system solutions for integrating the new technology into the schemes of existing enterprises are proposed - providing variability of adaptation in terms of raw material supply and the range of produced polycrystalline silicon of both “electronic” and “solar” quality. Based on the practical data obtained, system solutions were proposed for integrating the new technology into the schemes of existing enterprises - providing variability of adaptation in terms of raw material supply and the range of produced polycrystalline silicon of both “electronic” and “solar” quality.

Selective Separation of 4,4’-Methylenedianiline, Isophoronediamine and 2,4-Toluenediamine from Enzymatic Hydrolysis Solutions of Polyurethane

ABSTRACT The recycling of plastics such as polyurethane (PU) is a current challenge. The continuously increasing production volume and additionally growing end-of-life streams increase the urgency for solutions. Conventional recycling methods such as mechanical and chemical recycling are only economically and/or ecologically suitable to a limited extent. The three-step approach consisting of enzymatic PU decomposition, separation of amines (4,4’-methylenedianiline (MDA), isophoronediamine (IPDA), 2,4-toluenediamine (TDA)) and fermentation of the residual stream is a promising recycling concept. In this study, extraction methods for the separation of MDA and IPDA from an aqueous solution at neutral pH are developed. In addition, the influence of relevant PU hydrolysate components on the amine extraction is investigated. The results show that MDA can be efficiently separated using solvent extraction of 1-octanol. For IPDA separation, a reactive extraction with oleic acid as reactant is developed. The application of these two extraction methods to TDA shows extraction efficiencies of 52% to 86%. The other PU hydrolysate components adipic acid and selected salts have only a minor influence on the extraction efficiency. The diols ethylene glycol and 1,4-butanediol influence the equilibrium pH of IPDA extraction, raising it to higher values. For MDA, no influence of other PU hydrolysate components on the extraction efficiency can be observed. Since amines can have an inhibitory effect on microorganisms, toxicity experiments were carried out to determine the tolerable residual concentration of amines in the raffinate to avoid fermentation inhibition. Growth experiments with Pseudomonas putida KT240 show that MDA has an inhibitory effect at concentrations near the solubility limit, whereas IPDA does not affect growth.

Studies of spun concrete poles for electric power transmission line supports reinforced with Au1000P rebars

Introduction. In connection with the present volumes of electrification in central Russia, the need for the construction of new electric power transmission lines (EPTLs) has decreased considerably. At the same time, the natural degradation of EPTL supports in time, as well as the prospects for developing the vast expanses of the northern, Siberian and Far Eastern regions, caused by the reorientation of Russia’s economic relations from the West to the East, make it urgent to increase production volumes and technical and economic efficiency of using spun reinforced concrete poles for EPTL supports.Aim. Industrial implementation of spun reinforced concrete poles with the high-strength innovation profile reinforcement by replacing A800 rebars with four-row-profile Au1000P rebars.Materials and methods. The article provides data on the full-scale tests of spun reinforced concrete poles for EPTL supports according to the GOST 22687.1-85 “Centrifugal cylinder reinforced concrete posts for high-voltage transmission lines. Structure and dimensions” [1]. Three pole samples with a length of 26 m were prepared and tested. One sample consisted of prestressed A800 rebars according to GOST 22687.1-85, while the other two prototypes include the prestressed Au1000P rebars with the four-row profile. In the second sample, the reinforcement scheme (diameters and rebar quantity) repeats the standard option, increasing the bearing capacity of the pole. Having the same bearing capacity as the pole, manufactured according to the GOST, the third sample promoted for the reduction in the quantity of non-stressed rebars.Results. A new scheme for reinforcing the pole sample using Au1000P rebars was developed. The results of the sample testing are presented; a comparative evaluation of the pole strength and deformation characteristics is given; technical and economic indicators, as well as the recommendations regarding the reinforcement of the prestressed spun concrete poles with Au1000P rebars are provided.Conclusion. According to the results of the performed study, an economic effect was established due to a reduction in the quantity of non-stressed rebars by 28 %. Poles with Au1000P prestressed rebars have an increased corrosion resistance and durability due to the closing of cracks formed during the impact of short-term dynamic loads from wind gusts, wire breaks, etc. In terms of a recommendation, it is proposed to update the GOST 22687.1-85 in order to use new types of high-strength reinforcement rolled products and higher strength concrete.

Investigation of the mechanism of defect formation on reinforcements in multi-strain rolling with separation.

In the production of rolled metal products, along with physical and mechanical properties, much attention is paid to the quality of the surface. Proper surface quality of rolled rebar provides not only the presentation of products, but also high performance properties of products ‒ long-term trouble-free operation of reinforced concrete structures. In order to increase production volumes and increase the productivity of mills, most manufacturers of rebar of small profiles No. 8‒22 use rolling with separation into several threads ‒ the slitting process. With the slitting process, most surface defects are formed near or in the thread separation area. The correct classification of defects and the establishment of the nature of their formation is a very important stage necessary for the analysis of production technology and the development of measures to improve product quality. The paper studies in detail the mechanism of formation of surface defects on reinforcement No. 12 of steel grade 25Mn2Si during rolling with separation into four threads.

Quantitative analysis of the effects of incorporating laser powder bed fusion manufactured conformal cooling inserts in steel moulds over four types of defects of a commercially produced injected part

The introduction of additively manufactured conformal cooling inserts in steel moulds for plastic injection is becoming a recommended standard. Fine adjustment of the temperatures in the mould has demonstrated potential to reduce cycle times and to increase production volumes. Within this context, the present article explores the historical production data of a commercially produced part, before and after the incorporation of an L-PBF conformal cooling insert, to analyse what is the quantitative real effect on the efficiency of the production runs. The article analyses the change in the global rejection rates, and its effect over four different product defect types, i.e.: optical (surface), part integrity (bubbles, transparency, geometry), incomplete fill-in (interior), and breakages during extraction. The results demonstrate a specific decrease on the average appearance (from 20.53% to 13.48%; reduction of 7.05%) and variability (standard deviation from 14.16% to 6.81%; reduction of a 7.35%), of the global scrap rates, and a significant decrease in the scrap rates generated by optical defects and extraction part breakages. The article also characterises the former and the new processes by adjusting two distribution functions (Pareto Type-I and Weibull) and compares different estimates for the global expected scrap rates in past and future production runs.

Desain Mesin Pembuatan Gula Semut Berbahan Dasar Nira Kelapa Skala UMKM

Product development is a combination of technological trends that play a role in creating innovative works. Conceptual design is the initial phase of developing innovative product configurations. The processing of coconut sap into traditional palm sugar has constraints; the production process takes 4 to 6 hours and has a moisture content above 3%. The research objective was to obtain a machine design to increase production volume and reduce the water content in palm sugar. The machine design process begins with conducting interviews with 20 palm sugar craftsmen with approximately 5 years of experience to obtain information on priority needs. The VOC (Voice Of Customer) method can be used to determine priority designs and specifications. The results of the VOC process are (1) machine components made of food-grade materials, (2) production machines that are easy to operate and easy to maintain, (3) production machines with operational costs and affordable prices among MSMEs. The design development process has two alternative machines made using the Solidworks software. The results of the assessment of 30 SMEs’ palm sugar selected alternative two machine designs with dimensions of 70 x 60 x 155 cm. The advantage of the second engine design alternative is that it has a temperature sensor to adjust the gas valve and a pan with an insulator so that it can maintain temperature stability. The design of the palm sugar machine still requires innovation and development to increase production and quality.
