The intensification of animal husbandry is accompanied by an increase in demand for high-quality compound feed, which largely determines the level of development and economics of animal husbandry, especially industrial, specialized livestock farms. Reducing feed costs is one of the key challenges. Its solution is impossible without the rational use of grain and other raw materials, the introduction of modern innovative technologies and equipment at feed mills. Barothermal treatment of the grain mixture in the expander reduces bacterial contamination, completely destroys coliform bacteria, E. coli, mold fungi and salmonella. The technology for the production of expanded feed for broiler chickens was developed in the course of the work. Broiler chickens of the Smena 7 cross were used as the object of the study. It was found that the chicken palatability of the expanded compound feed developed with the help of the optimization program "Korm Optima Expert" improved and at the age of 28 days their live weight increased by 2.5–3 times in groups,  chickens that received grits from granular expandate having the highest indicator (915 g). At the end of the experiment 42-days old chickens of the control group had a live weight of 2246 g, and the chickens that received granulated expandate - 2574 g. The average daily gain in live weight of chickens was 66.4 g, which is 7.9% higher than in the control group. The results of the control slaughter of chickens showed an increased yield of meat in chickens treated with expanded pellets (69.5%) compared to the control (67.6%). The best indicators of the productivity of broiler chickens of the Smena 7 cross were obtained when feeding compound feed in the form of grains from granulated expandate in the first period of cultivation and granulated expandate in the second period of cultivation.
畜牧业的集约化伴随着对优质配合饲料需求的增加,这在很大程度上决定了畜牧业的发展水平和经济效益,特别是工业化、专业化养殖场。降低饲料成本是主要挑战之一。如果不合理使用谷物和其他原材料,在饲料厂引进现代创新技术和设备,就不可能解决这个问题。谷物混合物在膨胀机中进行气压加热处理,减少细菌污染,彻底消灭大肠菌群、大肠杆菌、霉菌和沙门氏菌。开发了肉鸡膨化饲料生产技术。以Smena 7杂交肉鸡为研究对象。发现鸡扩大配合饲料的适口性开发的帮助下优化程序“Korm Optima专家”提高,岁的28天活体重增加了2.5 - 3次组,鸡,收到粒状expandate粗燕麦粉(915克)的最高指标。实验结束时42天的老鸡对照组有活体重2246克,鸡,收到粒状expandate - 2574 g。试验鸡平均日增重为66.4 g,比对照组提高7.9%。对照屠宰鸡的结果显示,与对照组(67.6%)相比,使用膨胀颗粒处理的鸡的肉产量增加了69.5%。Smena 7杂交肉鸡生产能力的最佳指标是在培养第一阶段和培养第二阶段分别饲喂膨化颗粒和膨化颗粒复合饲料。

The article is devoted to the development of a mathematical regression model of the beet pulp  pressing process carried out on on a deep press extruder. The following parameters of beet pulp pressing were taken as initial ones: initial moisture content (before the extruder) and final moisture content (after the extruder); sugar content in the pulp before and after pressing; sugar content in the pulp; beet chips length before and after pressing; total biological contamination of sugar beet pulp; pulp acidity before and after pressing; acidity of the granulated pulp. The Fuzzy Logic Toolbox module included in the MatLab package is used to implement the proposed technique. The Surfase Viewer module is used to present the simulation results in a graphical form. Such studies were previously carried out with the CurveExpert 1.3 application package. The resulting equations adequately describe the change in the sugar content in the pulp and its nutritional value depending on the pulp acidity and moisture content, as well as the length of the sugar beet chips. The significance of the influence of each of the main technological parameters (acidity and moisture content of the beet pulp, the length of the beet chips) on the amount of sugar in the pulp and its nutritional value was determined in the work. The resulting quadratic dependences having sufficiently high coefficients R2, adequately describe the process of beet pulp pressing in a deep press extruder with an assessment of the influence of variable parameters on the content of residual sugar and feed units in beet pulp. The data obtained make it possible to objectively evaluate the work of a deep-pressing exstruder and justify the kinematic mode of the screws rotation, which allows minimizing the cost of finished products.
本文研究了在深压挤出机上进行的甜菜纸浆压榨过程的数学回归模型。将压榨甜菜纸浆的初始参数取为:挤出前的初始含水率和挤出后的最终含水率;压榨前后果肉含糖量;果肉含糖量;压榨前后甜菜片长度;甜菜果肉的总生物污染压榨前后纸浆酸度;造粒浆的酸度。使用MatLab包中的模糊逻辑工具箱模块来实现所提出的技术。Surfase Viewer模块用于以图形形式呈现仿真结果。这些研究以前是用CurveExpert 1.3应用程序包进行的。所得方程充分描述了纸浆中糖含量的变化及其营养价值,这取决于纸浆的酸度和水分含量,以及甜菜片的长度。在工作中确定了各主要工艺参数(甜菜果肉的酸度和水分含量、甜菜片的长度)对果肉中糖的含量及其营养价值的影响意义。所得到的二次依赖关系具有足够高的系数R2,充分描述了在深压挤出机中压榨甜菜果肉的过程,并评估了可变参数对甜菜果肉中残糖和饲料单位含量的影响。所获得的数据可以客观地评估深压挤出机的工作,并证明螺杆旋转的运动学模式,从而最大限度地降低成品成本。

The article provides a solution to the problem of studying the characteristics of resource efficiency for a given time interval in the form of solving an optimization problem (using dynamic programming methods and the method of recurrent Bellman equations. A multistep search for a solution was carried out for a given period of planning production activities. Boundary requirements were met in different ways due to the multivariate management decisions. The features of the optimization model were considered. The solution of the multistep problem is reduced to the sequential solution of several one-step optimization problems. The function of changes in resource efficiency in lean manufacturing technologies was set for the planning period. Changes in technologies for the capability involved demonstrate how resource efficiency changes with the observation time. It is noted thaqt the experience accumulation of experts and participants in the production process in the implementation of innovative approaches is of great importance for reducing all types of losses. It was revealed that one of the crucial parameters in a multi-criteria system is the preservation of efficient operation in the subsystem associated with intelligent decision support. The optimal amounts of costs have been determined. Their assessment was carried out to allow for the fact that when solving optimization problems, it is necessary to take into account such criteria for which the values take extrema. Assuming a successful solution of the optimization problem posed and analyzing the results obtained when dividing the multistep decision into three one-step ones, we received S-shaped functions with a function value equal to 6.8%
本文以求解优化问题的形式,利用动态规划方法和递归Bellman方程的方法,研究了给定时间间隔内资源效率特征的问题。在给定的生产活动规划期间,对解决方案进行了多步骤搜索。由于多元管理决策,边界需求以不同的方式得到满足。考虑了优化模型的特点。将多步优化问题的求解简化为若干单步优化问题的顺序求解。设定了精益制造技术中资源效率变化的函数。所涉及能力的技术变化演示了资源效率如何随观察时间变化。委员会指出,生产过程中专家和参与者在实施创新办法方面积累的经验对减少各种损失非常重要。研究表明,多准则系统的关键参数之一是保持与智能决策支持相关的子系统的高效运行。成本的最优数额已经确定。他们的评估是为了考虑这样一个事实,即在解决优化问题时,有必要考虑到这些值取极值的标准。假设所提出的优化问题求解成功,并将多步决策分解为三个单步决策分析结果,得到函数值为6.8%的s形函数

Locusts are insect species that can form migratory swarms, causing widespread destruction of crops and pastures, with significant impacts on food security. This article assesses the potential for beneficial use of locust swarms. Of the 21 known locust species, about ten species have traditionally been consumed by humans or fed to animals for thousands of years in 65 countries. Their nutritional composition is comparable to that of regular meat. However, insecticide residues, microbial contaminants and allergens can jeopardize the safety of their use. Several countries have developed regulations for edible insects, including locusts. In this article, prototypes of acrides were obtained and their chemical composition was determined - the content of crude protein, dry matter, crude fat, crude fiber, minerals, and the amino acid composition was determined. All studies were carried out according to generally accepted methods, based on the results of the studies, conclusions were drawn and possible methods of using acrides are described - locusts are rich in protein; minerals such as calcium, iron and zinc; a number of vitamins; useful fatty acids; in addition, the quantitative content of amino acids in locusts is higher than in meat products of slaughter. Safe and effective collection of locusts can help preserve agricultural land, as well as provide material as feed for animals and fish, and rearing locusts under incubation conditions can facilitate their use in food products in order to enrich them with protein or replace part of the raw materials.
蝗虫是一种可以形成迁徙群的昆虫,对作物和牧场造成广泛破坏,对粮食安全产生重大影响。本文评估了蝗群有益利用的潜力。在已知的21种蝗虫中,在65个国家中,约有10种传统上被人类食用或喂给动物,已有数千年的历史。它们的营养成分与普通肉类相当。然而,杀虫剂残留、微生物污染物和过敏原可能危及其使用的安全性。一些国家已经制定了包括蝗虫在内的食用昆虫法规。本文制备了丙烯酸酯样品,测定了其化学成分——粗蛋白质、干物质、粗脂肪、粗纤维、矿物质的含量,并测定了氨基酸的组成。所有的研究都是按照普遍接受的方法进行的,根据研究结果,得出了结论,并描述了使用丙烯酸酯的可能方法-蝗虫富含蛋白质;矿物质,如钙、铁和锌;多种维生素;有益脂肪酸;此外,蝗虫体内氨基酸的定量含量高于屠宰肉制品。安全有效地收集蝗虫可以帮助保护农业用地,并为动物和鱼类提供饲料材料,在孵化条件下饲养蝗虫可以促进它们在食品中的使用,以丰富它们的蛋白质或替代部分原材料。

The article discusses the features a distance learning system (LMS) organization of an educational institution, reflects modern approaches to the implementation of management decisions in educational organizations. Among the main advantages of using the LMS are free access to the training course, the adaptability and flexibility of the educational trajectory, the relevance of training, minimization of costs, simplified access to training materials for people with disabilities, synchronous and asynchronous educational process, depending on the current needs of the educational institution. The relevance of the information tools used and the reduction of various kinds of costs (labor resources, time costs) during their implementation are emphasized. Particular attention is paid to issues of a financial nature, including the rationale for choosing a platform for the implementation of LMS based on commercial, free access or a system developed by its own resources. It is noted that the use of the SCORM, Tin Can and similar formats in the development of their own LMS may fade into the background if an educational institution has its own standards for electronic documents of open formats, such as XML. The need to build a quality control system for the implementation of the educational process in the development of your own LMS is shown. The distinguishing features are the possibility of generating multi-level reports and the formation of learning statistics, as well as the possibility of analytics, depending on the changing needs of an educational institution for monitoring and managing the educational process in a remote mode. It is noted that individually developed LMS, in contrast to open and commercial ones, have the ability to add their modules for the analysis of statistics. The article provides data on the effectiveness of using this tool for all target groups (faculty, students, administrative staff, legal representatives of students) and their impact on the overall organization of the management process in the system of higher and secondary vocational education.
本文探讨了教育机构远程学习系统(LMS)组织的特点,反映了教育组织管理决策的现代实施方法。使用LMS的主要优点包括免费获取培训课程、教育轨迹的适应性和灵活性、培训的相关性、成本最小化、简化残疾人获得培训材料、根据教育机构当前的需求同步和异步教育过程。强调所使用的信息工具的相关性以及在实施过程中减少各种成本(劳动力资源、时间成本)。特别注意财务性质的问题,包括选择一个基于商业、免费访问的平台来实施LMS的理由,或一个由其自己的资源开发的系统。值得注意的是,如果教育机构对开放格式(如XML)的电子文档有自己的标准,那么在开发自己的LMS时使用SCORM、Tin Can和类似格式可能会退隐。在开发自己的LMS过程中,需要建立一个实施教育过程的质量控制体系。其显著特点是可以根据教育机构在远程模式下监测和管理教育过程的不断变化的需要,生成多层次报告和形成学习统计数据,以及分析的可能性。值得注意的是,与开放和商业的LMS相比,单独开发的LMS能够添加自己的模块来分析统计数据。本文提供了关于在所有目标群体(教师、学生、行政人员、学生的法定代表)中使用该工具的有效性的数据,以及它们对高等和中等职业教育系统管理过程的整体组织的影响。

The article provides data on the effectiveness of using this tool for all target groups (faculty, students, administrative staff, legal representatives of students) and their impact on the overall organization of the management process in the system of higher and secondary vocational education.","PeriodicalId":20611,"journal":{"name":"Proceedings of the Voronezh State University of Engineering Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88976020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The phenomenon of social responsibility is gradually penetrating the insurance business. He himself is also deeply socially significant. At the same time, the practices of participation of insurers in events and programs for the whole society, and not only for recipients of insurance services, are of particular interest. As a result of the study, a databank was formed that characterizes the participation of Russian insurance companies in socially oriented projects. It gives an idea of the scale of the supported initiatives, their focus and forms of implementation. The main forms of social interaction of insurance organizations at the municipal, regional and national levels were established. It has been proved that most of them can be considered as a full-fledged instrument of the social protection system of the population. The emphasis was made on the possibility of attracting their clients by insurance companies to participate in charity events. Such experience is a good example of social contribution, not only ensuring the implementation of social function and client participation, but also increasing the level of social responsibility of those who are initially considered exclusively in the role of recipients of insurance services. It was concluded that there is a relative diversity of initiatives supported by insurers, but at the same time, the involvement of representatives of the insurance community in social projects is extremely low. The main social tasks are presented, in the solution of which the resources of insurance organizations are currently involved.)
社会责任现象正在逐步渗透保险业。他本人也具有深刻的社会意义。与此同时,保险公司参与面向全社会的活动和项目的做法,而不仅仅是针对保险服务的接受者,特别令人感兴趣。作为研究的结果,形成了一个数据库,该数据库描述了俄罗斯保险公司参与面向社会的项目的特点。它提供了支持的计划的规模、重点和实施形式的概念。建立了市级、地区级和国家级保险组织社会交往的主要形式。事实证明,其中大多数可以被视为人口社会保护制度的成熟工具。重点是保险公司吸引客户参加慈善活动的可能性。这种经验是社会贡献的一个很好的例子,不仅确保了社会功能和客户参与的实施,而且还提高了最初被认为完全是保险服务接受者的人的社会责任水平。结论是,保险公司支持的倡议相对多样化,但与此同时,保险界代表参与社会项目的程度极低。提出了主要的社会任务,在解决方案中,目前涉及保险组织的资源。

Contemporary market of food of animal origin and its substitutes, i.e. dairy alternatives offers a range of non-alcohol beverages of plant origin (plant “milk”) of different level of particles’ dispersion. At Russian food market dairy alternative beverages are mostly cereal and food products by well-known brands. Application of alternative types of bean crops (green beans and haricot) in production of non-alcohol beverages of plant origin or synthetic products should be proven not only with consideration of their biological activity and their toxicity as well. The article deals with the results of comparative analysis of nutritional value and the evaluation stage of the basic toxicity of natural compositions of plant dispersion of germinated grains of bean varieties bred at Bashkir Research Institute of Agriculture and Omsk State Agrarian University in in vitro conditions. To estimate the level of toxicity and biological activity of natural compositions of plant dispersion of germinated bean grain of varieties Chishminskiy 95, Chishminskiy 229, Pamyati Khangildina, and haricot of varieties Omichka and Lukerya the most popular method for OZBlue - matter detection was used, i.e. the test on human civilized cell cultures HEK 293. It has been found out that plan dispersion of these varieties do not show the visible toxicity level in the interval of the concentrations under research, what gives a possibility to use them for targeted production.
当代动物源性食品及其替代品(即乳制品替代品)市场提供一系列颗粒分散程度不同的植物源性非酒精饮料(植物“奶”)。在俄罗斯食品市场,乳制品替代饮料主要是知名品牌的谷物和食品。在生产植物来源的非酒精饮料或合成产品时,不仅应考虑到其生物活性和毒性,还应证明替代类型的豆类作物(绿豆和花生)的应用。本文介绍了巴什基尔农业研究所和鄂木斯克国立农业大学培育的大豆品种发芽籽粒在体外条件下的营养价值对比分析和植物分散剂天然成分基本毒性评价阶段的结果。为评价Chishminskiy 95、Chishminskiy 229、Pamyati Khangildina和Omichka、Lukerya等品种发芽豆粒植物分散物天然成分的毒性和生物活性水平,采用了目前最流行的OZBlue - matter检测方法,即人类文明细胞培养物HEK 293。研究发现,这些品种的计划分散在研究浓度区间内没有显示明显的毒性水平,这为利用它们进行有针对性的生产提供了可能。

Kinetic aspects of bromination of a phthalate-type plasticizer 邻苯二甲酸酯型增塑剂溴化的动力学方面
Pub Date : 2021-12-22 DOI: 10.20914/2310-1202-2022-1-226-231

The main characteristics of a complex system of unsaturated plasticizer-bromine using the main "working components" - isomers of 2-ethylhexyl-2-ethylhexene phthalate are considered. It is taken into account that the phthalate-type ester plasticizer is a polar compound with a dipole moment at the level of dioctyl phthalate included in its composition. It has been shown that in the process of bromination, molecular bromine enters into physical interaction with all components of the plasticizer. Dosed introduction of bromine into the system at high stirring speeds leads to the formation of a homogeneous thermodynamically stable system, since the solubility parameters of the components are practically the same. Using a model mixture of bromine-dioctyl phthalate-dibutyl phthalate, it was shown that mixing bromine with plasticizers in any investigated ratios does not lead to the appearance of the boundary “bromine in a plasticizer” or “plasticizer in bromine”. This established the unlimited solubility of bromine in the plasticizer under the conditions of its bromination. Using the method of UV spectroscopy on model mixtures of acetic acid-bromine-water; acetic acid-bromine-hexane, it was proved that in a real system, unsaturated plasticizer-bromine, bromination is most likely carried out only with molecular bromine without the formation of bromine dimers. The mechanism of bromination of unsaturated phthalates included in the plasticizer is shown. A system of kinetic equations in dimensionless variables is proposed. It was found that the nature of the theoretical curves significantly depends on the rate of introduction of bromine with a constant reaction mechanism. A change in the limiting stages of the bromination process was noted depending on the rate of bromine introduction into the system.
考虑了以邻苯二甲酸2-乙基己基-2-乙基己烯同分异构体为主要“工作组分”的不饱和增塑剂-溴复合体系的主要特性。考虑到邻苯二甲酸酯型酯增塑剂是一种极性化合物,其偶极矩在其组成物中含有的邻苯二甲酸二辛酯水平上。研究表明,在溴化过程中,分子溴与增塑剂的各组分发生物理相互作用。由于各组分的溶解度参数几乎相同,以高搅拌速度向体系中适量引入溴可以形成均匀的热力学稳定体系。使用溴-邻苯二甲酸二辛酯-邻苯二甲酸二丁酯模型混合物,结果表明,以任何研究比例将溴与增塑剂混合都不会导致“增塑剂中的溴”或“溴中的增塑剂”边界的出现。这就确定了溴在增塑剂中在溴化条件下的无限溶解度。醋酸-溴-水模型混合物的紫外光谱研究醋酸-溴-己烷,证明了在实际体系中,不饱和增塑剂-溴,很可能只与分子溴发生溴化而不形成溴二聚体。研究了增塑剂中不饱和邻苯二甲酸酯的溴化反应机理。提出了一种无量纲变量的动力学方程组。结果表明,理论曲线的性质与溴的引入速率密切相关,反应机理不变。注意到溴化过程的限制阶段的变化取决于系统中溴的引入速率。

Various types of membrane units, including standard units for permeate separating, which are currently used for various liquids processing, are considered. Their advantages and disadvantages, working conditions and operating features are assessed. The principle of operation of membrane units with the bleed of the polarization layer is analyzed. A distinctive feature of such devices is the separation of the feed stream into three parts: adjacent to the membrane, including a polarization layer, with an increased concentration of high molecular substances (HMS) – concentrate, a spent stream core to be re-processed – retentate, and permeate, that practically contains no HMS. The unit scheme and the principle of operation of the plant completed with this equipment are given. A feature of this plant is the parallel arrangement of the membrane devices. In this configuration of the plant, there are two flow circulation loops and two tanks, in one of which there will be a depleted solution, in the other the retentate. During operation, the circulation of the depleted flow is provided. In this case, the resulting polarization layer (concentrate) will be discharged into the second tank. The working process continues until the complete depletion of the solution in the first tank. In the event that the solution in this tank is exhausted, and the required concentration of the product has not been reached, the second tank with the concentrate activates and the process continues. The principle of operation in this case is similar. The rotation of tanks continues until the required degree of concentration of the product is obtained. A calculation algorithm, a block diagram and a program for calculating the operating time of a membrane installation are proposed, for which a certificate of state registration of a computer program has been obtained. The calculation algorithm and program interface are presented. This program makes it possible to predict the operation of such installations and provides for the possibility of optimizing their operation.т.п.)
