Abstract:

Triticale (Triticosecale) is a crop species resulting from a plant breeder's cross between wheat (Triticum sp.) "mother" and rye (Secale sp.) "father". Today, it has been cultivated in more than 50 countries worldwide. During the researches conducted over period 2005-2006, the quality of three varieties of triticale was examined. Chemical quality parameters were the scope of the paper. The analyzed varieties of triticale showed high a-amylase activity, that was measured by falling number and amylolitic activity. While investigating thermal preparation of the samples at three different temperatures 60, 70 and 90?C, the optimum temperature was determined. Three different modes of thermal preparations were applied in the experiment: 1) without the addition of technical enzymes (a-amylase and glucoamylase), 2) with the addition of glucoamylase, and 3) with the addition of glucoamylase and a-amylase. The enzymes were dosed according to the recommendations of the manufacturer. The thermal preparation of samples conducted at 90?C, produced the lowest content of fermentable starch. This is due to inactivation of amylolytic enzymes in triticale at 90?C. During 2006, the survey on bioethanol production from triticale was directed towards lowering the temperature regimes of the preparation step up to 60?C. During the first preparation mode (without the additional enzymes), the obtained results for the content of fermentable starch and the ethanol yield, showed that native amylolytic enzymes of triticale can degrade 80-90% of the available starch. The addition of glucoamylase, during the second preparation mode, increased the content of fermentable starch and ethanol yield. The best results were achieved applying the third mode of preparation. Comparing the preparation modes, it could be concluded that the application of both a-amylase and glucoamylase in the preparation step increased the content of fermentable starch and ethanol yield by 7-13%. Further research should optimize the addition of a-amylase and glucoamylase. According to the results, the thermal preparation modes at 60?C are considered more suitable because of the energy savings.

Abstract:

Technological preparation of production (CCI) is a set of interconnected processes that ensure the technological readiness of an enterprise to produce a product of a given level of quality at a specified time, volume of production and costs. Technological preparation of production consists of several stages: design of technology, organizational and economic training. Purpose of the article: Organization of technological preparation of the production process for the manufacture of the workpiece details "Frame 3V". In the work, an analysis of the manufacturability of the design is to be performed, the official purpose of the part is described and the grade of the material of the part is characterized. To develop a technological process for the manufacture of this part with an indication of the processing methods, create a statement of the technological process equipment and organize a frame manufacturing site. In addition, it is necessary to draw up terms of reference for the design of the fixture and tool. At enterprises with single and small-scale production, decentralized preparation of production is used, since a one-off production is carried out.

Abstract:

Introduction. The study offers a new rational approach to processing cottage cheese whey and using it as a highly nutritional functional ingredient in food production. We proposed a scientifically viable method for hydrolyzing cottage cheese whey with enzyme preparations of acid proteases from Aspergillus oryzae with an activity of 400 units/g and a pH range of 3.0 to 5.0. Study objects and methods. Pre-concentrated whey was enzymatically hydrolyzed at 30°C, 40°C, and 50°C for 60 to 180 min (pH 4.6). Non-hydrolyzed whey protein concentrates were used as a control. The amount of enzyme preparation was determined by calculation. All hydrolysate samples showed an increase in active acidity compared to the control samples. Further, we conducted a full-factor experiment with three levels of variation. The input parameters included temperature, duration of hydrolysis, and a substrate-enzyme ratio; the output parameters were the degree of hydrolysis and antioxidant capacity. Results and discussion. The experiment showed the following optimal parameters for hydrolyzing cottage cheese whey proteins with the enzyme preparation of proteases produced by Aspergillus oryzae: temperature – 46.4°C; duration – 180 min; and the amount of enzyme preparation – 9.5% of the protein content. The antioxidant capacity was 7.51 TE mmol/L and the degree of hydrolysis was 17.96%. Conclusion. Due to its proven antioxidant capacity, the whey protein hydrolysate obtained in the study can be used as a functional food ingredient.

Abstract:

The article is aimed at verification of the effect of chaff length of fermented material and duration time of the contact of material with oxygen before dosing into the fermenter, on production and energy content of biogas. The results of the verification showed an effect of chaff length in the fermented material on production and energy content of the biogas at processing grass silage with high content of dry-matter and especially maize silage. When processing maize silage, optimal length of chaff in terms of production and energy content of biogas was 13 mm, with grass silage it was from 69 to 112 mm. Verification of the influence of time of grass silage and maize silage contact with air oxygen before dosing into the fermenter did not confirm our hypothesis. It was demonstrated that production and energy content of the biogas increase together with the length of duration of 7 days compared to fermentation of material after max. 3 h of contact with air oxygen.

Abstract:

Tomato crops (Solanum lycopersicum) under conventional production system are constantly treated against pest and diseases, with organic synthetic pesticides that are used may cause serious disturbance to environment and human health. This research was carried out in order to study the effect of homeopathic and high dilution preparations on pests and diseases management of tomato crop under organic production system. Two experiments were conducted under field conditions and one in greenhouse. All of them in randomized block design with the cultivar Santa Cruz Kada. The treatments consisted of homeopathic preparations Staphysagria, Arsenicum album, Sulphur, Arnica montana, high dilution preparations of Solanum lycopersicum and Solanum aculeatissimum, at the decimal (DH) or centesimal (CH) scale of hahnemanian high dilution. Bordeaux mixture, cupric preparation, and Bacillus thuringiensis were also included in weight doses. The preparation Arnica montana 12DH increased the tomato yield under field conditions. The damage incidence of small borer was efficiently reduced with applications of Sulphur 12CH that equalling to B. thuringiensis. The same treatment did not reduce the large borers. B. thuringiensis reduced also the septoria leaf spot incidence in the field. In greenhouse, the high dilution preparation of tomato at 12DH completely suppressed the septoria leaf spot and drastically reduced the same disease at 24DH. The homeopathic and high dilution preparations have the potential to be effective on replacing pesticides that are used on tomato, and could be suitable to fill legal requirement for organic production system.

Abstract:

The article presents the data about the preparation of recovered paper using dry method. The objective of this method of fiber preparation is to reduce water and energy consumption as well as obtaining higher physical and mechanical characteristics of the cardboard. There is used a dispergator parts of which are constructed with 3D printer. After dry defibration, the purification is carried out. Acquired finely dispersed, refined material is used to produce the three-layer cardboard – test-liner. According to standard methodologies, there were determined such mechanical parameters of multi-layer test-liner as breaking length, bursting strength. Obtained results can be used to produce multi-layer testliner to reduce energy costs, as well as water consumption. As a result of this research, it turned out that using the method of preliminary dry dispersion of fibers, it becomes possible to reduce metal volume of the equipment as well as energy and water consumption. Previously, the mechanical grinding of recycled fibers was not carried out. Therefore the data presented in this article allow assess the cost of applying this method into the industry. The method of dry dispersion, which was carried out and studied in laboratory conditions, is not currently applied in the paper and cardboard industry of Russia, despite its advantages. In the future, it is planned to conduct repeated studies, with a view to the possible introduction of this method into the industry.

Abstract:

Introduction: Chronic inflammatory diseases of the upper respiratory tract of both microbial and viral origin occur due to the immune deficiency of systemic and local nature. Among a large number of immunomodulation agents, a special role belongs to plant preparations, which are characterized by relative harmlessness and high efficiency, both in case of systemic and local use and they are often combined with antimicrobial agents, therefore the aim of the study was to investigate their effect on the reactions and condition of lymphoid cells of tonsilswith separate and combined use in vitro. Methods: Cell suspensions were prepared mechanically and adjusted to a concentration of 2 million/ml in medium 199 with additives. Then, Lizak preparation was added to the cells and starch solution was used in control. Imupret and Esberitox preparations were added to the culture with or without Lizak preparation. After cultivation, the levels of proinflammatory cytokine – Interleukin-1β, pro-allergic factor – Interleukin-4, Th-1 – derivative of cytokine – interferon-γ were studied in the supernatant using the «Tsitokin LLC» reagent kits (RF), as well as tissue regeneration factor – transforming growth factor –TGF-1β (Austria). The preparation was prepared from the cell pellet, in which the relative nonviable cell count was determined in a sample with trypan blue using a light microscope (Olympus CX21FS1).The statistical analysis was performed using Student's t-distribution. Results: Plant-derived preparations did not have any effect on cell viability in culture, did not reduce the level of the pro-inflammatory cytokine interleukin-1β and did not stimulate the production of the regeneration factor TGF-1β. At the same time, the combined use of plant-derived preparations and the antibacterial preparation Lizak in cell culture of tonsils was accompanied by an increase in cell viability compared to the use of Lizak preparation separately, the stimulation of the regulatory antiviral factor interferon-γ and an increase in the production of tissue regeneration factor. Conclusion: The immunomodulating properties of the antibacterial preparation Lizak and plant-derived immunomodulator Esberitox significantly differ in the points of application. Both plant-derived preparations stimulated the production of γ-interferon by tonsil cells in the presence of Lizak preparation, the transforming growth factor TGF-1β, the viability of tonsil cells was the highest with the combination of Lizak and Esberitox.

Abstract:

The preparation of flavors and fragrances has to be done with great care. When these compounds are meant for consumption, no toxic chemicals are allowed during their preparation. For use in non-food additives, a high purity is required. Both constraints can be easily fulfilled when enzymes are used as catalyst during the production of these compounds. This paper summarizes the work that we have done regarding the preparation of branched-chain fatty acids (sheep flavors) using lipases, the production of glucosides (controlled-release flavors) using glucosidases, the formation of terpene alcohols and grapefruit flavor using enzymes from chicory, and the formation of phenolic antioxidants using lipases.

Abstract:

Abstract Sustainable fodder production, feeding capacity, and high animal productivity are the basis of effective animal husbandry. Nutritious, high-quality feed additives and vitamin premixes have been delivered to Russia from Denmark, France, Belgium and other countries for many years. However, it is possible to improve the feeding value of grains and their accessibility for animals through innovative solutions in using balanced concentrates or dry feed technologies. Regarding current conditions, it is only innovation-oriented development of dairy farming that will reduce milk production cost, ensure profit increase, and consequently production profitability, by means of technological, organizational and economic innovation, an optimal combination of primary, auxiliary and service production. The article discusses new approaches to organizing the use of grain fodder on farms enabling them to provide dairy cattle with more nutritious feeds, realise animal genetic potential, reduce feed costs by about 7-10%, thus improving animal husbandry profitability. An organizational and technological innovation has been proposed in the case of Limited Liability Company «Agribusiness Firm «YUMA» in Krasnodar Territory. Introducing feed preparation unit extruder KMZ-2U will increase milk production profitability from 11 to 16.3%.

The dependence of the hydrolysate bitterness on the decrease of the EP proteolytic activity in the presence of PMSF, an inhibitor of serine proteases, was observed. It was found that the use of Neutrase provided non-bitter hydrolysates, while the proteolytic activity of Neutrase decreased by 44% in the presence of PMSF. A domestic EP of Protosubtilin lost 59% activity in the presence of PMSF and formed bitter hydrolysates. Casein hydrolysates obtained using Alcalase were characterized by the most severe bitterness, probably due to the fact that almost all proteolytic activity in this preparation is represented by a serine protease. The Bacillus subtilis 359 strain with a ratio of neutral and serine protease activities of 52 to 48% was selected from the VNIIPBT Collection of Bacterial Producers of Proteases. The concentrated preparation was obtained from the culture liquid of B. subtilis 359 strain by spray-drying. The preparation obtained hydrolyzed casein similarly to Neutrase and ensured the absence of bitterness in hydrolysates. neutral protease, serine protease, bitterness of hydrolysates, Bacillus subtilis This work was financially supported by a Grant of the Basic Research Program of the Russian Academy of Sciences for 2019-2021 (Project no. 0529-2019-0066).

Abstract:

Epidermal growth factor–urogastrone (EGF-URO), a polypeptide of about 6000 atomic mass units present in humans, mice, rats, and other mammals that is widely recognized for its mitogenic and acid-inhibitory activities, was observed to cause contraction of helical arterial strips of the rat ileocolic artery and to potentiate the action of KCl on helical strips from the superior (cephalic) mesenteric artery. The contractile effect of EGF-URO in ileocolic preparations displayed marked tachyphylaxis at high EGF-URO concentrations (100 ng/mL). The apparent mean effective concentration for EGF-URO in these tissues was about 10 ng/mL (1.7 nM); the detection of EGF-URO degradation in the organ bath indicated that a half-maximal response may have been achieved at a concentration as low as 50% of this value (i.e., about 0.9 nM). The actions of EGF-URO were abolished by indomethacin (3 μM) and were, in part, mimicked by prostaglandin F2α (PGF2α), which contracted the ileocolic preparation and potentiated the action of KCl in the superior mesenteric preparation. In the superior mesenteric preparation, PGF2α alone, like EGF-URO, did not have an appreciable effect on resting tension. The time fag of the EGF-URO effect in the ileocolic preparation (5–6 min to reach peak contraction) corresponded closely with the time course of EGF-URO-stimulated calcium accumulation measured previously in other cell systems. Our results suggest that EGF-URO acts to modulate contractility in vascular tissue via a cyclooxygenase pathway product (possibly PGF2α). Our data point to a role for EGF-URO and possibly other growth factors in the control of vascular function.

Abstract:

The production of xylanase (XylA) by Aspergillus niger JL-15 in solid-state fermentation (SSF) on orange peel was optimised by the response surface methodology (RSM). The results revealed that four factors had significant effects on the XylA production (P < 0.05), that is the concentrations of the added glycerin and ammonium sulfate, the moisture content, and fermentation time. Exploying orange peel as the solid substrate, maximum xylanase activity (917.7 U/g dry fermentation product) was obtained at 4.2% glycerin, 3.1% (NH<sub>4</sub>)<sub>2</sub>SO<sub>4</sub>, 61% moisture content, and 73.4-h fermentation, this activity being close to the predicted one and 3.2 times higher than that of the basic medium (218.5 U/g). Optimum temperature and pH for XylA activity were 55°C and pH 5.0, respectively. SDS-PAGE analysis showed that the relative molecular mass of XylA was about 30.0 kDa. XylA exhibited K<sub>m</sub> and V<sub>max </sub>values of 9.24 mg/ml and 54.05 μmol/min/ml, respectively. XylA liberated mainly xylotriose from birchwood xylan and wheat bran, respectively. XylA was an endo-acting xylanase with transglycosylation activity, with the ability to hydrolyse, xylobiose, xylotriose, xylotetraose, xylopentaose, and xylohexaose.

Abstract:

In this paper, realistic production-inventory models with shortages for a deteriorating item with imprecise preparation time for production (hereafter called preparation time) has been formulated and an inventory policy is proposed for maximum profit in a finite time horizon. Here, the rate of production is constant, demand depends on selling price, marketing cost, and inventory level, and setup cost depends on preparation time. The imprecise preparation time is assumed to be represented by a fuzzy number and is first transformed to a corresponding interval number and then following interval mathematics, the objective function for total profit over the finite time horizon is changed to respective multi-objective functions. These functions are maximized and solved for a set of Pareto optimal solution with the help of the weighted sum method using the generalized reduced gradient technique. Different case studies have been made depending upon the occurrence of shortages. The models have been illustrated by numerical data. Pareto-optimal solutions for different weights are obtained and presented in tables and graphs.

Abstract:

Currently, the technological processes of preparation of alfalfa as fodder in the rice crop rotation in the districts of Kyzylorda region and the coefficient of technical readiness of equipment used for mechanization does not exceed 0,7 and the load per unit of equipment is 1.2-1.6 times higher than the norm. The article considers the interaction between the technical means of preparation of alfalfa as fodder and the probable nature of the processed material and the factors influencing the external environment, taking into account the interrelationships between them. In order to substantiate the technology of alfalfa preparation, the general service theory (GPP), probability theory, reliability theory were used. Experimental studies were conducted in irrigated fields of Kyzylorda oblast and using natural experiments, time calculations and simulation models developed using experiments. The results of the research were processed using the methods of probability theory and mathematical statistics. On the basis of natural and computational experiments of technology of preparation, transportation and storage of fodder, analytical dependences of performance indicators of the main natural and technological factors characterizing operating conditions of system are defined. operating modes allow to increase the efficiency of production processes of preparation, transportation and storage of fodder in real production conditions.

Abstract:

The key task of the tool manufacturing is to create or to choose such a type of tool, which would permit to provide high processing efficiency, the best tool`s workability and the quality of the machined surfaces with minimum expenses and resources. The optimal choice of the constructive tool modifications from a variety of options takes much time required for the preparation of the tool to work. To solve this problem, we have developed software that allows you to create, organize and carry out a comparative analysis of structural instruments in order to identify rational option for the given conditions of production. Ordering and selection of a rational design of the instrument is carried out in accordance with established procedures of modeling and comparative analysis of design solutions. Application software can reduce design time technological process by 80...90%, and get a substantial annual economic effect.

Abstract:

The insufficient occurrence of raw material resources on our territory was one of the historical reasons for marginal production of sulphated binders from secondary raw-material resources. Also the unprofitability of material production based on calcium sulphate was related to this fact. This was changed in the end of the last century when formation of waste raw materials increased with industrial development. Secondary gypsums became basic raw material for production of plaster boards, plaster mixtures and anhydrite self-levelling mixtures. Wet flue gas cleaning desulphation process during which the energogypsum is formed is nowadays realised in major part of our power stations. Annual production of the energogypsum produced in this way in particular power stations is about 250 kt. The energogypsum is generally stored in stock piles as a so called stabilisate and partially is delivered to cement works as a solidification regulator. Chemogypsum is produced in chemical works where waste waters with content of SO42- occur, which must be desulphated with lime in water ambient. Further it is formed in citric acid productions where also sulphated waters occur. Last but no least it is also produced in industrial production of phosphates. Production of titanium dioxide is another example of the industry where the possibility of gypsum formation exists.

Abstract:

Wider exploitation of computer integrated manufacturing (CIM) in shipbuilding is inevitable as yards seek continuing improvements in productivity and quality to sharpen competitiveness. The buzz word CIM has been used in many ways through the years. The correct interpretation may be the integration of all computer systems directly supporting the definition and production of the ship. This comprises CAD and also administrative systems such as planning and material control programs. CIM in this paper is defined as optimal utilization of CAD data and planning data in shop floor production, including feedback to the planning system and accumulation of quality data. The paper defines the state-of-the-art of CIM solutions at shipyards, and outlines a case study of one larger CIM installation. The case presented shows the structure of one installed system, and outlines the experience gained through planning, preparation and installation of the system. The case also includes cost budgets for the installation, including necessary training for planners and operators. Important organizational issues when planning the structure of CIM based production is described in the case. Terms such as Central Work Preparation and Local Work Preparation are introduced. The tasks performed in each area that add value to the CIM data files are described. At the end of the paper, the authors have outlined some future thoughts on further developments of CIM at shipyards. Important issues are, e.g., on-line production simulation systems capable of constantly updating the planning system in order to ensure the highest possible productivity and to support just in time (JIT) philosophies in all areas of the production.
