Published: April 2022

Os eventos de tempestade têm sido mais frequentes e intensos nas últimas décadas, provocando a destruição de construções e inundações ao longo da costa brasileira. Neste contexto, o presente estudo tem como objetivo a caracterização morfológica e sedimentar do sistema praia-barreira arenosa de Jaconé-Saquarema, assim como a identificação das áreas mais suscetíveis ao impacto das ondas de tempestade. A metodologia deste estudo contou com mapeamento da planície costeira; aquisição de 142 perfis topográficos; coleta de 78 amostras de sedimentos, para análise granulométrica e morfoscopia; e cálculo do volume emerso de sedimentos da praia. Os resultados mostram que a barreira holocênica apresenta uma altura entre 5,1 e 6,2 metros; a barreira pleistocênica, ligeiramente mais preservada, chega a alcançar 7,2 metros de altura, acima do nível médio do mar. A praia apresenta uma dinâmica elevada, resultado da intensa energia das ondas de tempestade e da interação destas com o costão no extremo oeste de Jaconé. Uma ligeira diminuição na energia é observada em direção a Saquarema, que apresentou as menores variações na largura e morfologia, reflexo da presença das rochas de praia de Jaconé, que interceptam parcialmente as ondas de tempestade neste trecho da costa. Os sedimentos que compõem o sistema praia-barreira são constituídos por areias quartzosas, moderadamente selecionadas, bem arredondadas a subangulares, com diminuição no tamanho dos grãos de oeste para leste, variando de areia muito grossa a média, respectivamente. No setor oeste, excepcionalmente, as rochas de praia atuam como uma barreira paralela à linha d’água permitindo a acumulação de areia fina e muito fina, mal selecionada, na praia, contrastando com a elevada dinâmica de ondas tão característica na área de estudo.

The paper proposes an engineering calculation method, on the basis of which it was proposed to use three ultrafiltration units connected in series for the ultrafiltration separation of cheese whey components. These installations operated in a continuous cycle, which contained membrane devices with the calculated parameters. This paper describes a scheme for obtaining whey protein concentrate from cheese whey formed during the processing of milk into rennet cheese. The scheme works on a tubular ultrafiltration apparatus - it was accepted for development at ChS VERO LLC. In our proposed scheme, an electrodialysis unit is used, since this unit has more advantages than others. The advantage of the electrodialysis unit is the demineralization of technological solutions with a high dry matter content (concentrated whey, gelatin, sugar syrup, chicory syrup, glycerin) and tolerance. The productivity of the selected electrodialysis plant allows the concentrated volume to be brought to a demineralization level of 80% in about 1 hour. The work describes in detail the scheme of the concentration line for LLC "VEKSHA" and LLC "ChS" VERO "with obtaining dry whey concentrate, including a tube-type ultrafiltration apparatus. Also substantiated is the value determined by the ratio of the results of production and labor costs and funds for the production of cheese whey for LLC "ChS" VERO "and LLC" VEKSHA ". The expected economic effect from the introduction of the line will be 4200 thousand rubles. for LLC "VEKSHA" and 980 thousand rubles. for LLC "ChS" VERO "per year in prices of 2021.

Published: April 2022

The production of beer that meets the requirements of consumers in terms of quality and price is one of the most important aspects of competition in their sales market. It is known that the quality of the beer is associated with colloidal stability, which is often achieved through the use of different methods, such as chemical, enzymatic and physicochemical methods. Chemical methods are used to reduce the rate of oxidative processes in beer by introducing antioxidants. At the same time, enzymatic methods are often used in the mashing step. They involve enzyme preparations to regulate the levels of protein and carbohydrates (?-glucans and dextrins) in the beer. In breweries, physicochemical methods based on adsorbents that help remove major haze components such as protein and polyphenols from beer are commonly used. Since expensive imported materials such as silica gel and PVPP are widely used in Russia, which leads to additional production costs, this work is devoted to studying the possibility of reducing the costs of beer stabilization by replacing imported silica gels with domestic ones. For the study, we used domestic silica gels manufactured by "Tovesorb" (Russia). In addition, we used silica gels of foreign production Stabifix (Germany) and Britesorb L10 (Netherlands) as a control. The obtained results showed the prospects of using domestic brands of silica gel from "Tovesorb" (Russia), which were not inferior to imported analogues in terms of their adsorption properties.

Published: April 2022

The article is devoted to increasing the efficiency of kefir production through the use of the simulation method, which allows you to create a multi-agent simulation model that describes the real processes of the studied production in the virtual space. The advantages of using simulation models in comparison with conducting experiments in a real system and using other methods are shown. Such a model allows you to obtain detailed statistics on various aspects of the functioning of the system under study, depending on the input data, reflecting the processes as if they were happening in reality. The article defines the relevance of the topic. It is shown that in the process of producing kefir there are problems typical for the market: constantly changing consumer demand for products, the emergence of new varieties of products, new technologies and modern progressive equipment. To meet these requirements, a flexible, rapidly restructuring production organization scheme is needed, which will work effectively with the introduction of an intelligent system for automatic quality control of kefir production and will contribute to a quick and effective restructuring of the technological equipment used, as well as technological modes of production. Therefore, the analysis of the structure of the dairy enterprise from the point of view of the main events of the modeled system was carried out, on the basis of which a logical and mathematical model of kefir production in the form of a multiphase multichannel system was developed and presented. Also, a systematic analysis of the automation object - the kefir production line was carried out. All stages of kefir production are considered, taking into account the information processes occurring in them, which made it possible to develop a flow diagram of the relationship between different workshops and raw material flows in the production of kefir. The carried out experimental studies allowed to obtain a multi-agent simulation model of kefir production. To implement the presented model, the software product AnyLogic was used. After the development of this model, 2D and 3D simulation models of the kefir production process were presented to test its operability. This article lists all the agents of the model.
Promising Russian developments in the production of flour products with flax seeds and products of their processing
Authors: Efremov D. P.
Published: April 2022

The article is devoted to the systematization of scientific developments of domestic scientists in the sphere of oilseeds flax processing and their use in technologies of flour products. Oilseed flax is the only oilseed crop in which almost all anatomical parts are important for industrial processing. The use of oil flax in the food industry is due not only to the presence of biologically valuable nutrients, but also to the functional and technological properties inherent in the products of their processing. It is shown that along with whole and ground flax seeds, not only flax seeds processing products (full-fat, semi-fattened, skimmed and oil), but also bran and cryopowder from seeds are widely used in the above food technologies. Flax seed hydrocolloids or dry polysaccharide extract deserve special attention, which are of interest not only from the technological point of view (analog of xanthan gum, guar gum), but also from the medical and biological position, since they perform prebiotic function in the human body. Analysis of numerous domestic sources of scientific, technical and patent information allows us to conclude that flax seeds are, on the one hand, a well-known and widely used raw material. On the other hand, it should be noted that there are still a number of insufficiently elaborated directions, in particular, additional research is needed, which will allow to realize on an industrial scale economically competitive technologies of production of flour products, maximizing the potential (technological and medical and biological) of non-starch polysaccharides, lignans and other biologically active compounds of flax seeds

The article shows the possibility of using the piezo quartz microweighting method and a portable device model based on highly sensitive piezoweights for express assessment of the concentration of actual resins in diesel fuel. A comparative characteristic of the methods for determining the actual resins in diesel fuel is given: the standard Budarov method is evaporation to a dry residue under a jet of water vapor to a constant mass, the fractional distillation method is heating to the evaporation temperature, cooling the gas fraction and measuring the volume of the non-distillable residue. The device of highly sensitive quartz piezoweights, the main patterns, characteristics during operation are considered. Samples of diesel fuel of the brand L-0,2-62 GOST 305-82 "Diesel fuel" were selected as objects of research. Technical specifications" of different manufacturers and filling dates provided in the fleet of the FVA RVSN im. Peter the Great (Serpukhov city). The results of a study of diesel fuel according to standard methods for determining the content of actual resins, cetane number, density, kinematic viscosity, acidity, water–soluble acids and alkalis, mechanical impurities and water content, fractional composition - distillation temperatures of 50 and 96% of fuel, flash point in a closed crucible, turbidity temperature and solidification temperature, test on a copper plate are presented. The characteristic of the operational properties of each sample is given. The method of piezo-quartz microweighting with a one-way load of the investigated diesel fuel breakdown of the resonator electrode, mass-sensitive (OAV-type), is applied. The correlation between the results obtained by piezo-quartz microweighting and the standard method was studied. The possibility of using the piezo-quartz microweighting method for the development of express out-of-laboratory determination of non-volatile residue in diesel fuel is positively evaluated.

Published: April 2022

The paper considers the possibility of using highly dispersed modified aluminosilicates in the process of extracting hydrogen sulfide from wastewater. The problem of the presence of hydrogen sulfide in natural waters is due to the impossibility of using such waters in human household activities. Water with a high content of hydrogen sulphide has low organoleptic properties, is not suitable for consumption and is highly corrosive. Produced water generated in the process of oil production must also be treated. In the presence of hydrogen sulphide in the produced water, further water injection into the reservoir is highly discouraged, as this can lead to "plugging" of oil-bearing channels. In this regard, the work proposes a method for extracting hydrogen sulfide from natural and waste waters. The work synthesized a new adsorption-coagulation material based on modified aluminosilicates (bentonite clays) using salts of multivalent metals. The possibility of creating a reagent with a different ratio of aluminosilicate matrix: modifier is considered. It was found that the efficiency of the reagent increases with an increase in the pH of the medium. The activity of the reagent in relation to hydrogen sulfide, clarification and removal of oil products was studied. The capacity of the reagents obtained as a result of the modification can reach 32 mg/g in terms of hydrogen sulfide. In the reagent, it is possible to vary the ratio of aluminosilicates and modifiers, which can facilitate the use of the most effective reagent, depending on the conditions. The reagent is capable of extracting not only hydrogen sulfide, but also oil products from the processed aqueous solutions. The reagent binds hydrogen sulfide into insoluble forms, after which the precipitate can be separated from the solution and disposed of.

Published: April 2022

The increasing relevance in the field of repair and restoration of machines and mechanisms is acquiring gas-thermal methods of applying functional coatings to the working surfaces of parts of machine assemblies. The purpose of gas-thermal coating methods is to provide and obtain special physical and mechanical properties of the surface of the part, as well as to restore worn-out components and mechanisms after their long-term and intensive operation. Plasma spraying of composite coatings is an effective method of gas-thermal treatment of the surface of a part. In this paper, a study was conducted on the optimal selection of material for plasma spraying of a part, taking into account its operational features and types of wear of working surfaces. In particular, the operating conditions of the screw of the conveying conveyor are analyzed. The technological features of the application of composite materials by plasma spraying technology are considered. The theoretical selection of a two-phase dispersed-filled composite for application to the working surfaces of the screw in order to restore and harden it has been carried out. Studies and analysis of one of the main indicators of the quality of the formed coating after plasma spraying – the magnitude of the resulting residual stresses (stretching and compression) have been carried out. Taking as a basis the kinematic modes and geometry features of the working surfaces of the screw, as well as the criteria for the formation of the thickness of the sprayed layer, the calculation equations for determining the residual stresses arising on the screw and cylindrical surfaces of the screw of the conveying conveyor are obtained. It is concluded that in order to achieve the required physical and mechanical properties of the coating, the volume fraction of the filler in the matrix of the PG-SR4 composite powder should be in the range of 20–25%. Therefore, it is possible to use in practice a particulate-filled composite of the NiСrВSiFе type with 20–25% reinforcing TiC filler particles in order to restore parts of machines and mechanisms.
Research of ostrich fat properties when melting in electrochemically activated medium

Published: April 2022

In recent decades, there has been a growing scientific interest in various kinds of technologies using electro-activated solutions with high reactivity and representing a powerful toolkit for intensification of production processes. However, theoretical knowledge about the regularities of change in fat properties during melting in an electrolyte is rather fragmentary, scarce and often contradictory. The work is devoted to the study of the main factors influencing the change in physical and chemical properties and yield of fat in the process of melting using catholyte, to substantiate the feasibility of its use and develop an industrial line for obtaining fat. The object of studies was ostrich fat obtained by traditional method – by melting in water and by experimental technology – in catholyte as well as technological regimes of fat extraction. According to the data obtained, the fat melted at pH of catholyte 11, temperature 100 and 75 °С was characterized by low values of acid number – 0,45 mg KOH/g and 0,40 mg KOH/g, respectively. The opposite trend was observed with a successive decrease in the alkalinity of the ECA medium and an increase in the melting temperature of the fat, which led to an increase in the content of secondary oxidation products in the experimental samples. It was found that due to the high reactivity of the EСA medium, the temperature and pH of the catholyte increased, the intermolecular interaction within the fat phase decreased, which increased the mobility of lipid molecules relative to each other. The lowest values of fat viscosity (0,42 and 0,4 kPa?s) were recorded when treating fatty raw materials in catholyte with pH 10.5 and 11 and temperature 100 °С. It is shown that increasing the pH of the catholyte contributes to minimizing the values of peroxide number of ostrich fat, in contrast to the heating temperature. It is established that processing of raw materials in catholyte at 75 °C resulted in the yield of fat 88,4–90,1%, which is almost 1,4 times higher than when melted in water. In the wet method of mellowing in water, denaturation of protein structures and a higher degree of fat extraction can be achieved at a mellowing temperature above 75 °C, in contrast to the proposed method of processing raw materials.

Published: April 2022

The development of the modern transport industry makes increased demands on the reliability and efficiency of road transport equipment, as well as tightening environmental standards. This applies not only to improving the elements of the internal combustion engine (ICE), transmission and suspension, but also to improving the properties of fuel and engine oil. For the mechanical activation of MWCNT and MoS2, the vortex layer apparatus ABC-150 was used - the mechanical action of which is carried out due to the movement of grinding bodies (cylindrical) in an alternating electromagnetic field, as well as the Pulverisette 5 planetary mill (spherical bodies). The studies carried out show that mechanical activation causes heating of dispersed MWCNTs and MoS2, which, when dispersing in a liquid flow, requires limiting this process precisely by the temperature parameter. At the same time, it should be noted the possibility of simultaneous mechanical activation and distribution of MCNT and MoS2 in fuel or engine oil, which ensures high processability of the process and reduces costs associated with the need to use additional equipment. Mechanical activation in a planetary mill is accompanied by a higher uniformity of the temperature field, but at the same time in ABC the process of mechanical activation is more intense and requires less time.The presented technology of mechanical activation can be used to increase the efficiency of distribution of MCNTs and MoS2, both in fuel and in engine oil. Temperature control can be carried out by varying both the mechanical activation time and the number and type of grinding bodies

Published: April 2022

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.

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.)

The work noted the relevance of the development of the military-industrial complex of Russia. An analysis of sales volumes of a number of the largest enterprises of the military-industrial complex of the Russian Federation was carried out, as a result of which two leading organizations were identified. The value of the sales indicator for one analyzed enterprise was evaluated, indicating the reasons for the high results in three enterprises. Based on the analysis of data on the number, conclusions were made about the priority of large enterprises in the structure of the military-industrial complex of the Russian Federation and about the rather serious attention paid by the state to the development of the military economy in modern conditions. When considering the territorial location of the analyzed enterprises, the employment of employees of large organizations of the MIC industries in various regions of Russia is clearly shown, which serves as one of the main factors in the development of the regional economy throughout the country. It was noted the place of the largest enterprises of the military-industrial complex in the ranking of the 100 largest military-industrial companies in the world, based on income from sales of military products by world manufacturers in 2020. The build-up of the country's military power directly depends on the potential of military-industrial complex enterprises and the directions of their development. In the ranking of the analytical company GlobalFirepower for 2020, Russia was ahead of China, but lost to the United States. There are different opinions about the objectivity of this and similar ratings. However, it is impossible not to pay attention to the values of those factors in the GlobalFirepower rating, which indicate insufficient attention to them from the military-industrial complex of the Russian Federation at the present time.

The article deals with issues related to the mechanization of methods existing in Russian practice that allow assessing the level of influence on favorable conditions for the development of small innovative enterprises based on military institutions, and a new comprehensive indicator, which, when creating this database, is a general index of innovation. Based on two factors illustrating only opportunities for development and favorable conditions, and the true results of this activity, methods are proposed for predicting the importance of each element in terms of its impact on the level of innovative development, and, based on this, innovators are usually offered approaches to assigning weight modules to factors used in various methods of calculating the indicator. In the conditions of the current financial crisis, the reason for the success of small enterprises is the impact of their new development system and getting more opportunities for their functioning, to ensure a high level of planning of production processes in small companies. The author examines the Pleiades Correlation Graphs, which is formed based on the method of compiling a list of conditions that affect the development of small enterprises for small businesses based on military companies, to see how small enterprises are in transition. Thus, a methodology for the influence of favorable conditions on the development of small innovative enterprises based on military institutions is proposed, the choice of factors and the principle of assigning weight coefficients for them are substantiated, and a variant of the development of this methodology is shown. Further research is needed to obtain a more complete picture of the relationship between enabling environments and the development of small innovative enterprises based in military institutions.

Published: April 2022

On the basis of official statistical data on the structure and existing risks of the formation of Russia's foreign trade turnover in comparison with other developed countries, the objective need for import substitution has been substantiated, the acceleration of which and an increase in the role in ensuring the country's economic growth depends not only on the effectiveness of measures taken by the state and the business community, but and from a clear quantitative assessment of its performance. A comprehensive assessment of the effectiveness of import substitution was carried out on the basis of a wide range of statistically reliable single indicators reflecting the impact of import substitution on the state and dynamics of development of the most important sectors of the national economy – its domestic production, exports, imports, and the socio-economic sphere. In order to model and calculate a complex indicator of the effectiveness of import substitution on the basis of the formed system of single indicators, the method of principal components was used, implemented in the Statistica application software package and which made it possible to compress the generated array of multidimensional information to a limited number of more informative features (the main component for each block of indicators) up to the final a comprehensive indicator of the effectiveness of import substitution. The indicators that have the greatest impact on the effectiveness of import substitution in each block of indicators have been identified. Based on the regression analysis, a high positive correlation was found between the integrated indicator of the effectiveness of import substitution and economic growth. Using the method of multicriteria optimization, the parameters of import substitution have been determined, which, in real economic conditions, at the prevailing rates and scales of GDP, enhance the positive impact of import substitution on economic growth.

The problem of technical solutions for the implementation of a software and hardware complex for food quality management is considered. The review and analysis of existing modern control systems is presented, which made it possible to conclude that today food enterprises need new effective solutions using highly efficient intelligent technologies. The analysis of the possibility of intellectualization of the food production quality management system is carried out. The main tasks of this system are presented. It is shown that a practical basis for the implementation of this problem can be the creation of a software and hardware complex for an automated food quality control system using artificial intelligence technologies, which includes neural network technologies, computer vision systems, simulation modeling and an effective combination of hybrid methods and technologies in its arsenal. Methods, algorithms and technologies for the development of the investigated software and hardware complex of an intelligent automated food quality control system are analyzed. The developed generalized functional structure of such an intelligent system and the main stages of its implementation are presented. The main types of support for this system have been developed: information, mathematical and software. The main stages of decision-making on the quality of finished food products have been developed. The necessary technical means are recommended for the implementation of the system. For the practical implementation of the developed intelligent system, the CP1EE14DRA controller from Omron was chosen - a modular programmable controller. As an operator's workstation, a choice should be made in favor of Siemens products - SIMATIC Panel PC. For the tasks of data storage and implementation of calculations, a conventional personal server equipped with a powerful processor, for example, IntelCorei7, has been proposed.

Due to the stabilization and growth of meat production, the demand of the Russian population for meat products at the expense of its own production is provided by 77%, the country continues to be the largest exporter of meat and meat products, which damages its economy. Russia's share in global meat production is significantly lower than its potential and is about 2%. The rapid growth of various probiotics and feed additives currently being diagnosed is taking on a wide scale and is the basis of the biosafety system of livestock products. The effectiveness of the use of probiotic drugs is related to the mechanism of their action, which consists in their ability to produce a wide range of biologically active substances. The prospects of using probiotic additives in the industry of industrial rabbit breeding to increase the meat productivity of young rabbits are considered. Scientific and economic experiments were carried out on the number of rabbits in production conditions: LLC "Lipetsk rabbit" of the Lipetsk region. It is proved that the inclusion of a complex probiotic preparation based on Vetom 3.0 and Vetom 1 in the feed diet of rabbits has a positive effect on the chemical composition and flavor profile of the meat resources obtained. A comprehensive study of rabbit meat obtained using the developed scientific approaches showed that this type of raw material is characterized by an increased protein content (up to 21.55–21.94%) with a simultaneous decrease in adipose tissue. The calculation of economic efficiency showed that the introduction of a complex probiotic based on Vetom series drugs into the production cycle increases the level of profitability from 9.34 to 42.24%, while reducing feed costs by 0.89 ECU and increasing the slaughter yield of rabbits by 2.96%.

Fruit and berry mousses used as desserts and cake fillings have low nutritional value due to protein deficiency. Legumes can be used as ingredients for enriching sweet dishes. The aim of the work was to study and substantiate the possibility of using beans seeds in the technology of dessert mousse of increased biological value. The objects of the study were samples of seeds of white beans (Phaseolus vulgaris) and mousses prepared on their basis. This type of beans is constantly presented on the Russian market and is the main one in canning. Investigations were carried out: the chemical composition of bean seeds was determined, a recipe for bean mousse was developed, an analysis of the nutritional value, consumer properties and shelf life of the new product was carried out. Standard laboratory methods of analysis were used. Boiled crushed beans (bean paste) were added to the mousse. In boiled beans, compared to dry seeds, the water content increased from 7.7 to 58.9%, protein decreased from 22.9 to 8.2% (in dry matter 24.8–20.2% ). Based on the analysis of the influence of the amount of beans on the formation of the structure and organoleptic properties of the mousse, the optimal content of beans in the mousse was established - 40%. The developed mousse recipe includes: boiled beans, additional flavoring substances (sugar, fruit or berry juice), a structurant (gelatin), water. Bean mousse is characterized by a high protein content (over 6%) and dietary fiber (over 3%), moderate calorie content (160 kcal/100 g of product), lack of preservatives and flavor enhancers, therefore it can be classified as a healthy food.

The research aimed to justify the production of quark from a normalized mixture with whey protein hydrolysate using Advanced Technology (АТ) and acid coagulation to reduce the allergenicity of the finished product. The whey protein hydrolysate obtained with the help of the enzymes Promod 439L and Flavorpro 766MDP was proposed as a component of normalization and consistency stabilizer because it characterized by reduced allergenicity and a high content of biologically active peptides. The chemical composition of the finished product and its microbiological properties as well as microstructure were determined using standard arbitration and generally accepted research practices. It was found that the replacement of 30% of skimmed milk in the normalized mixture with whey protein hydrolysate has a positive effect on the consistency of the finished product and allows to reduce allergenicity at 50%. The excessive content of hydrophilic whey proteins, as well as peptides, contributes to the formation of consistency and moisture retention inside the dispersed system without syneresis. The experimental sample characterized by high concentration of living cells of starter microorganisms (more than 109CFU/gr) and high survival rate of the starter microflora during the storage (more than 4 times in comparison with the control sample). The additional proteolytic breakdown of milk proteins during the fermentation leads to the reduction of the antigenicity of proteins. The developed curd product can be recommended as part of dietary and general diets as biologically complete product with reduced allergenicity. This approach provides a closed cycle for processing raw materials at dairy enterprises.
Smart City Data Science: Towards Data-Driven Smart Cities with Open Research Issues

Published: April 2022

Cities are undergoing huge shifts in technology and operations in recent days, and `data science' is driving the change in the current age of the Fourth Industrial Revolution (Industry 4.0 or 4IR). Extracting insights or actionable knowledge from city data and building a corresponding data-driven model is the key to making a city system automated and intelligent. Data science is typically the study and analysis of actual happenings with historical data using a variety of scientific methodology, machine learning techniques, processes, and systems. In this paper, we concentrate on and explore ``Smart City Data Science", where city data collected from various sources like sensors and Internet-connected devices, is being mined for insights and hidden correlations to enhance decision-making processes and deliver better and more intelligent services to citizens. To achieve this goal, various machine learning analytical modeling can be employed to provide deeper knowledge about city data, which makes the computing process more actionable and intelligent in various real-world services of today's cities. Finally, we identify and highlight ten open research issues for future development and research in the context of data-driven smart cities. Overall, we aim to provide an insight into smart city data science conceptualization on a broad scale, which can be used as a reference guide for the researchers, professionals, as well as policy-makers of a country, particularly, from the technological point of view.

L-asparaginase (ASNase) is an aminohydrolase currently used in the pharmaceutical and food industries. Enzyme immobilization is an exciting option for both applications, allowing a more straightforward recovery and increased stability. High surface area and customizable porosity make carbon xerogels (CXs) promising materials for ASNase immobilization. This work describes the influence of contact time, pH, and ASNase concentration on the immobilization yield (IY) and relative recovered activity (RRA) using Central Composite Design methodology. The most promising results were obtained using CX with an average pore size of 4 nm (CX-4), reaching IY and RRA of 100%. At the optimal conditions, the ASNase-CXs biocomposite was characterized and evaluated in terms of kinetic properties and operational, thermal and pH stabilities. The immobilized ASNase onto CX-4 retained 71% of its original activity after six continuous reaction cycles, showed a good thermal stability at 37 °C (RRA of 91% after 90 min) and was able to adapt to both acidic and alkaline environments. Finally, the results indicated a 3.9-fold increase in the immobilized ASNase affinity for the substrate, confirming the potential of CXs as a support for ASNase and as a cost-effective tool for subsequent use in the therapeutic and food sectors.
