Authors: Hufnagl Christine , Kriner Hildegard , Marcus Laura , Schröder Jürgen
Published: December 2021

Um die Digitalisierung von Prozessen erfolgreich voranzutreiben und cyber-physische Systeme sinnvoll zu nutzen, ist der Dreiklang aus Identifikation, Lokalisation und Zustandsermittlung in Echtzeit von allen prozessbeteiligten Faktoren unabdingbar. Derzeit fehlt es an Strukturen, welche diese Kriterien ausreichend berücksichtigen. Die Notwendigkeit dafür wird im Folgenden aufgezeigt und beispielhaft anhand der Bettenlogistik eines Krankenhauses demonstriert. Dieses Vorgehen ist auf alle logistischen Prozesse der Produktion übertragbar.

Published: December 2021

In presynaptic terminals, membrane-delimited Gi/o-mediated presynaptic inhibition is ubiquitous and acts via Gβγ to inhibit Ca2+entry, or directly at SNARE complexes to inhibit Ca2+-dependent synaptotagmin-SNARE complex interactions. At CA1-subicular presynaptic terminals, 5-HT1Band GABABreceptors colocalize. GABABreceptors inhibit Ca2+entry, whereas 5-HT1Breceptors target SNARE complexes. We demonstrate in male and female rats that GABABreceptors alter Pr, whereas 5-HT1Breceptors reduce evoked cleft glutamate concentrations, allowing differential inhibition of AMPAR and NMDAR EPSCs. This reduction in cleft glutamate concentration was confirmed by imaging glutamate release using a genetic sensor (iGluSnFR). Simulations of glutamate release and postsynaptic glutamate receptor currents were made. We tested effects of changes in vesicle numbers undergoing fusion at single synapses, relative placement of fusing vesicles and postsynaptic receptors, and the rate of release of glutamate from a fusion pore. Experimental effects of Prchanges, consistent with GABABreceptor effects, were straightforwardly represented by changes in numbers of synapses. The effects of 5-HT1Breceptor-mediated inhibition are well fit by simulated modulation of the release rate of glutamate into the cleft. Colocalization of different actions of GPCRs provides synaptic integration within presynaptic terminals. Train-dependent presynaptic Ca2+accumulation forces frequency-dependent recovery of neurotransmission during 5-HT1Breceptor activation. This is consistent with competition between Ca2+-synaptotagmin and Gβγ at SNARE complexes. Thus, stimulus trains in 5-HT1Breceptor agonist unveil dynamic synaptic modulation and a sophisticated hippocampal output filter that itself is modulated by colocalized GABABreceptors, which alter presynaptic Ca2+. In combination, these pathways allow complex presynaptic integration.

SIGNIFICANCE STATEMENTTwo G protein-coupled receptors colocalize at presynaptic sites, to mediate presynaptic modulation by Gβγ, but one (a GABABreceptor) inhibits Ca2+entry whereas another (a 5-HT1Breceptor) competes with Ca2+-synaptotagmin binding to the synaptic vesicle machinery. We have investigated downstream effects of signaling and integrative properties of these receptors. Their effects are profoundly different. GABABreceptors alter Prleaving synaptic properties unchanged, whereas 5-HT1Breceptors fundamentally change properties of synaptic transmission, modifying AMPAR but sparing NMDAR responses. Coactivation of these receptors allows synaptic integration because of convergence of GABABreceptor alteration on Ca2+and the effect of this altered Ca2+signal on 5-HT1Breceptor signaling. This presynaptic convergence provides a novel form of synaptic integration.

Published: December 2021

When implementingdevelopmentconcepts inthe electric power industry(such as“Smart Grid”, “Digital substation”and“Outsourcing of services”), the task of ensuring stablerelay protection operationsand automation devices is urgent. The problem is solved according to the developed structural-information (SI) method. A method for selective search of theoptimal amount of structured information for automatic decision-making is proposed. The article discusses an algorithm for recognising scenarios for the development of semantic events, which is included in the SP-method. The algorithm is applied uniformly for all hierarchical levels of recognition, based on the goals of decision making at the senior level. Control of the sequence of information events is performed in the dynamics of the passage of events along one path from all relationships according to the structural-informationmodel.Part 1 shows a collaborative structural-information model consisting of a shaping tree in a dynamic object and a recognition tree in devices. A theoretical description of the algorithm is given using the amplitude and time (Ξ,Η) selectivity windows in the general structural scheme of S-detection. The application of the method for different hierarchical levels of recognition is shown.The decision-making results are presentedin two forms, by means of a single semantic signal to indicate a group of resultsandfilling in the table of the sequence of occurrence of the recognised elementary information components. Part 2 shows the application of the SP-method at different hierarchical levels of recognition for the synthesis of a selective relay, which implements an algorithm for finding a damaged network section with single-phase ground faults in 6-35 kV distribution networks with a Petersen’scoil. The reasons for the unstable operation of algorithms of known selective relays are indicated, based on the concepts of scenario recognition. The improvement of the structure of a selective relay operating on the basis of the criterion for monitoring the coincidence of the firsthalf-waves of the mid-frequency components in the signals of transient processes is considered. Examples of the synthesis of elementary detectors of absolute,relative and cumulative actions in relation to a selective relay are given, which make it possible to fill the amount of information for general S-detection.The simulation of the operation of the synthesisedS-detector on the signals of real emergency files of the natural development of damage to the isolation of the network phase and simulation of artificial scenarios of events in the mathematical SI-modelare carried out.
EL PLURALISMO RELIGIOSO EN EL JOVEN HEGEL. ESPACIOS COMUNES DESDE LOS QUE GENERAR UN DIÁLOGO INTERRELIGIOSO
Authors: Ortigosa Andrés
Published: December 2021

El pluralismo religioso trata de presentar lugares comunes en los que establecer diálogos entre diferentes religiones sin intención de persuadir. En esta investigación se aborda el pluralismo religioso en los periodos de Tubinga y Berna de Hegel. Esto es, en la filosofía del joven Hegel, periodo en el que se dedicó especialmente a la reflexión sobre la política y la religión. En este periodo, menos estudiado por la academia que su madurez, encontramos que hay al menos tres lugares comunes que pueden facilitar el diálogo interreligioso: el sentimiento, la universalidad ética y la libertad. En esta investigación se presenta estos tres tópicos que Hegel descubre para el diálogo entre diferentes religiones para, finalmente, conectarlos con la discusión cronológicamente posterior sobre el pluralismo religioso.

Jóvenes, delito y “limpieza social” en Bogotá
Authors: Pabón Suárez Ingrid Carolina
Published: December 2021

A partir de la experiencia de vida de Camilo, un habitante del sector de Patio Bonito, este artículo muestra cómo jóvenes que habitan contextos barriales en condiciones de pobreza se vuelven visibles por las prácticas en las que incurren al trasgredir pactos de convivencia, y no por la condición marginal. Me interesa mostrar que son uno de los grupos poblacionales victimizados por una práctica violenta reconocida ampliamente como “limpieza social”. ¿Cuál es la base cultural que soporta el despliegue de violencia por parte de jóvenes en sus contextos barriales? Dos claves arrojan el trabajo etnográfico: la masculinidad y la noción de respeto. ¿Cómo se conecta esto con una práctica violenta como la “limpieza social”? Para responder esta pregunta doy cuenta de lo que configura la indeseabilidad de un sujeto-joven.

Boundedness of the Maximal Function of the Ornstein-Uhlenbeck semigroup on variable Lebesgue spaces with respect to the Gaussian measure and consequences
Authors: Moreno Jorge , Pineda Ebner , Urbina Wilfredo
Published: December 2021

The main result of this paper is the proof of the boundedness of the Maximal Function T* of the Ornstein-Uhlenbeck semigroup {Tt}t≥ 0 in Rd, on Gaussian variable Lebesgue spaces Lp(.) (γd); under a condition of regularity on p(.) following [5] and [8]. As an immediate consequence of that result, the Lp(.) (γd)-boundedness of the Ornstein-Uhlenbeck semigroup {Tt}t≥ 0 in Rd is obtained. Another consequence of that result is the Lp(.) (γd)-boundedness of the Poisson-Hermite semigroup and the Lp(.) (γd)- boundedness of the Gaussian Bessel potentials of order β > 0.
Teacher educators’ understanding of integrating lesson study into pre-service teacher education
Authors: Win Yin Mar
Published: December 2021

In Myanmar, according to the National Education Strategic Plan (NESP) 2016–2021, the four-year Education College curriculum has been developed and implemented, in line with the pre-service teacher education reform. In the new curriculum, the Lesson Study (LS) model is integrated into the practicum. LS is an effective teacher professional development practice that originated in Japan and is becoming popular all over the world today, suited to both pre-service and in-service teacher education. The LS concept has been introduced to the Myanmar context since 2011 through international training projects and there are two LS research projects which focus on the impacts of the training. However, there is no follow-up research which explores teacher educators’ understanding of LS and their LS practices after the training projects and there is no research related to the integration of LS into pre-service teacher education. This study explores the LS experiences and perspectives of teacher educators who have to take the responsibility of integrating LS into pre-service teacher education with the aim of assessing their readiness for that. Eight teacher educators from six Education Colleges in Myanmar participated in this qualitative research project. Semi-structured interviews were conducted for data collection. The results reveal that teacher educators are already familiar with the term “LS” through the former LS projects. Moreover, the findings show two dimensions of teacher educators’ lesson study experiences; namely, lesson study experiences as a tool of professional development and as a tool of teacher training. They have positive perceptions about the integration of LS into the practicum but it is still challenging for them.

Published: December 2021

Proteases of Lactobacillus and Lactococcus strains catalyze casein degradation in fermented dairy products, which can result in the production of bioactive peptides. Proteolytic properties of a selection of lactic acid bacteria (LAB) strains previously isolated in Croatia, including Lactococcus lactis and Lactobacillus strains, are described. All strains of Lactobacillus and Lactococcus showed an Fmc+ phenotype that can be associated with efficient growth in milk. The significant caseinolytic effect, after incubation of culture supernatant or concentrated cell biomass, was observed for Levilactobacillus brevis D6 and Lactiplantilactobacillus plantarum D13 after growth in the optimal growth medium, while for Lc. lactis ZGBP5-32 and Levilactobacillus brevis SF9B strains after growth in skimmed milk. To assess the LAB growth in skimmed milk, the acidification rate was monitored. Statistically, significant acidification capacity was determined for L. plantarum D13 in the optimal medium and by the proteolytic strain L. helveticus M92 in skimmed milk. After extraction of proteinases from the strains with caseinolytic activity, protein samples were analysed by the SDS-PAGE method. The protein extract of the strains Lc. lactis ZGBP5-32 and ZGZA7-10, retained proteolytic activity even at very low concentrations. The ultrafiltration improved protein extraction which possibly contained putative protease, as a decrease in contaminating proteins was confirmed by SDS-PAGE in samples of L. brevis D6 and SF9B, L. fermentum D12 and L. plantarum D13.

Authors:   Faculty of Philosophy and Social Sciences, Nicolaus Copernicus University in Toruń, Poland, Nalaskowski Filip , Dejna Dagna ,   Faculty of Philosophy and Social Sciences, Nicolaus Copernicus University in Toruń, Poland
Published: December 2021

The article is a research report on candidates for archaeological studies, for which the source of data was the Internet Candidate Registration (IRK) system of the Nicolaus Copernicus University in Toruń. The analysis was carried out on a sample of 695 people admitted to the first year of archeology at UMK, with the material covering the period from 2007 to 2017. It was decided to build the profile of candidates for students based on six criteria: the size of the hometown and its distance from Toruń, gender, age of the candidates, completed secondary school, results of secondary school-leaving exams and recruitment decisions of candidates (priority system). As researchers, we had no influence on the set of data we had at our disposal, the work was carried out using an already existing database, the primary purpose of which was not research or analyzes similar to ours. The text presents conclusions and generalizations based on proprietary tools for the analysis of the existing database. The conclusions, although they concern archeology itself and candidates for archeology, may be a starting point for further analyzes of other majors. Archaeologists can use these outcomes to evaluate the condition of their discipline.

The Medieval Christian Necropolis in the Kopachyntsi hillfort (Ukraine). Unpublished Research Materials
Authors:   I. Krypiakevych Institute of Ukrainian Studies National Academy of Sciences of Ukraine,, Lutsyk Iryna
Published: December 2021

The article deals with unpublished research materials from the medieval Christian cemetery located on the territory of the hillfort in the village of Kopachyntsi in Sub-Carpathian region (Ukraine) which were conducted in 1953. Excavations were verified, objects and artefacts were analysed, and an attempt to attribute and date them was made. The site is represented by inhumations in pits, as well as burials under stone slabs. The so-called “under the slab burials” are a separate category of monuments of funeral culture, which is characterized by its diffusion only on the territory of Halician-Volhynian state, but not the whole of Kyiv Rus’. At the same time, such monuments are known in Slovakia, Czech Republic, Germany, Bulgaria, Romania, Macedonia and Poland. Data on most of the under the slab monuments discovered on the territory of Ukraine are often uninformative, and therefore the publication of the results of stationary archaeological excavations is extremely important for understanding this cultural and religious phenomenon. Special attention is paid to a rare stone cross that was found by the deceased. The search for analogies allows us to conclude that it may be a pilgrimage relic.
Development of a heuristic to solve the general transportation problem
Authors: Munapo Elias
Published: December 2021

The transportation problem is well known and has very important applications. For this well-researched model, there are very efficient approaches for solving it that are available. These approaches include formulating the transportation problem as a linear program and then using the efficient methods such as the simplex method or interior point algorithms.
The Hungarian method is another efficient method for solving both the assignment model and the general transportation model. An assignment problem is a special case of the transportation model in which all supply and demand points are 1. Every transportation problem can be converted into an assignment problem since rows and columns can be split so that each supply and each demand point is 1.
The transportation simplex method is another method that is also used to solve the general transportation problem. This method is also called the modified distribution method (MODI). To use this approach, a starting solution is required and the closer the starting solution to the optimal solution, the fewer the iterations that are required to reach optimality.
The fourth method for transportation models is the network simplex method, which is the fastest so far. Unfortunately, all these approaches for transportation models are serial in nature and are very difficult to parallelize, which makes it difficult to efficiently use the available massively parallel technology. There is a need for an efficient approach for the transportation problem, which is easily parallelizable. This paper presents a See-Saw approach for solving the general transportation problem. This is an extension of the See-Saw approach for solving the assignment problem. The See-Saw moves can be done independently, which makes the approach proposed in this paper more promising than the available methods for transportation models
Mathematical modeling of the sedimentation process for determining the fractional composition of suspensions
Authors: Chumak Vitalii , Maksymiuk Mariia , Kosenko Olena , Rudenko Vira , Spaska Olena
Published: December 2021

Exceptional prospects for use in science, technology and industry are opened by highly dispersed powders (ultradispersed diamonds, nanoceramics, medicinal powders) and materials based on them. The properties of such materials depend on the particle size determined by sedimentation analysis.
An equation is proposed for processing sedimentation analysis data, which does not depend on the size distribution law of polydisperse system particles, and is used to describe the distribution functions of particles with radii for clay suspensions.
A program in the Microsoft Visual Basic for Applications (VBA) language has been created for calculating the fractional composition of suspensions according to the proposed equation; the correctness of its operation on a model system has been checked and confirmed.
Experimental research has confirmed that the use of the developed program and the "Search for a solution" add-on for the MS Excel environment makes it possible to determine the fractional composition of suspensions.
It has been proven that the proposed method can be used to analyze polydisperse systems.
It has been found that for the suspensions under consideration, as containing 25 fractions, it is possible to determine the integral curve of the distribution of the masses of the particles of the dispersed phase along the radii.
This allows to assert the possibility of using the proposed equation for processing sedimentation analysis data, which does not depend on the law of mass distribution of polydisperse system particles by size.
Thus, there is reason to assert about the possibility of a reasonable determination of the fractional composition of any polydisperse systems.
It is possible to obtain certain effects from the introduction of sedimentation analysis data processing according to the proposed equation in production, where the fractional composition of dispersed phases is regulated.
Energy power parameter effect of hot rolling on the formation of the structure and properties of low-alloy steels
Authors: Sheyko Sergey , Matiukhin Anton , Tsyganov Volodymyr , Andreev Andrey , Ben Anna , Kulabneva Elena
Published: December 2021

The temperature and degree of hot deformation for steel 10HFTBch have been determined. This made it possible to ensure an increase in the mechanical properties of this steel, namely, the ultimate strength up to 540–560 MPa, as well as the relative elongation up to 25–29 %. As a result, it became possible to increase the service life of wheels with increased carrying capacity. This, in turn, will make it possible to increase the load of the transported cargo by motor vehicles several times.
The mechanism of the influence of the energy-power parameters of rolling on the formation of the macro- and microstructure of a two-phase steel in the process of hot deformation is disclosed. The applied scheme provided an increase in the homogeneity of the structure of the developed steel, which saved the central part of the rolled section from overheating. It has been established that a decrease in the temperature of the end of deformation leads to a decrease in the size of the recrystallized austenite grain, and, consequently, to a refinement of the ferrite grain. Also an important factor in preventing the growth of ferrite grains in the upper part of the ferritic region is the abolition of cooling of the steel in coils.
The recommended mode for multicomponent alloy steel 10HFTBch is as follows: the temperature of the end of rolling is 850 °C, the beginning of accelerated cooling is 750 °C, and the temperature of strip coiling into a coil is 600 °C.
The basis for ensuring the increased strength of two-phase steels is the ratio and distribution of structural fractions – ferrite (initial and precipitated from austenite), as well as martensite. When hardened by such traditional "martensite formations" as manganese, the ability to control properties is limited. This is reflected in a narrow range of variation in the strength and ductility of the developed steel. The optimal combination of strength characteristics of plastic properties reduces the metal consumption of the product by 15–25 %.

Published: December 2021

Starch is a product of intensive processing of agricultural products. During the processing of plant starch, nutrients such as protein, dietary fiber, and minerals are removed. In addition to nutritional imbalance, rich nutrients have an impact on the environment. The object of research is Areca taro, a starch-rich agricultural product.
The research aims to use spray drying technology to obtain a whole betel nut taro powder for food processing, such as sausages and noodles. The taro is used as a raw material, and the whole taro flour is obtained after peeling, cutting, crushing with water, and spray drying. Using single factor and orthogonal experiment to optimize the spray drying process parameters and embedding agent of taro powder, and then analyze its physical and chemical properties.
The results show that adding 0.01 % Xanthan gum+0.12 % Microcrystalline cellulose (embedded agent) to the taro emulsion can increase the extraction rate of taro flour, speed up the drying speed, and prevent sticking to the wall. The best process of spray drying: the speed of atomizer was 16000 r/m, the wind temperature was 200 °C, the material liquid concentration was 28.00 % and the feeding rate was 75 mL/min. The taro powder produced by this process has better liquidity, light purple color, smooth texture, and strong flavor of taro. Product parameters: powder fluidity was 13.9 cm, extraction rate was 15.36 %, water activity was 0.416, chromaticity parameters were 19.73 (L* value), 2.96 (a* value) and 3.25 (b* value), bulk density was 0.44 g/mL.
This technology can provide data support and reference for food processing companies. The taro whole powder would be widely used as food ingredients in future.

Published: December 2021

The object of research is the components of an intelligent system for searching information in electronic repositories of unstructured documents, which based on the ontologies of the subject area. One of the most problematic areas is the processing and analysis of information contained in electronic repositories of unstructured documents. There are considered the some possibilities of increasing the efficiency of information processing. In the course of the study, using the method in which ontologies comprise sets of terms presented in it. In addition, the ontological set also includes information about subject areas, areas of definitions, etc. There are obtained the sequence of defining the conceptual representation of an intelligent search system based on ontological components. There are presented the composition of the ontological system model. There are described the main functional components of the system for intelligent processing of information about electronic documents.
The proposed approaches for identifying the component components of the ontological model of the search system have a lot of features. This is due to the fact that the search system model must have a set of properties: integrity, coherence, organization, integrability, mobility. Ontologies which representing the basic concepts of the domain in a format available for automated processing in the form of a hierarchy of classes and relationships between them allow automated processing. The using of ontologies in the role of an intermediary between the user and the search process, between the search process and the search system that can facilitate the solution of a number of complex and non-standard tasks of information retrieval (for example, the automation of the search process). It is possible to solve the problem of knowledge representation for displaying information relevant to user requests, as well as to solve the problems of filtering and classifying information. Compared to similar well-known search systems, this provides such advantages as creating a common terminology for software agents and users, protecting the information store from total overflow and errors, as well as solving the issue of information aging.
Development of a method for improving the accuracy of measurement of linear measures of 3D models via scanning
Authors: Kvasnikov Volodymyr , Ornatskyi Dmytro , Dostavalov Valerii
Published: December 2021

The object of research is to refine the linear sizes of the obtained 3D models via scanning, and reducing the numbers of errors when obtaining the model. For now, there is no accuracy method for transferring the actual sizes of an object to a 3D model. One of the most problematic places in the existing methods of transferring sizes from the object to the model is the error in the placement of dimensional markers due to inaccuracy, or poor quality of the received surface via scanning.
A model of the instrument complex is used to implement an improved method of 3D scanning, based on the photogrammetric method. The advanced technology of construction and measurement of 3D models on the basis of photos on the principle of stereo pairs in combination with image projection is based on a combination of existing scanning methods. As well as the introduction of new functionalities, such as maintaining the actual sizes of an object, its textures, color and light characteristics, as well as improving the accuracy of linear sizes.
As a result of the use of a standard, reference projections, and a new method of comparing photographs to build a 3D model, a 60 % increase in the accuracy of linear dimensions was achieved. This is due to the fact that the proposed new combined method incorporates all the existing most important aspects of scanning. And also has a number of features, such as the definition of boundary surfaces, automatic sizing, detection, and processing of glass and mirror surfaces. Due to this, this method eliminates the main disadvantages of the usual photogrammetric method – inaccuracies in the surface quality of the models, and inaccuracies in the transfer of linear dimensions. It is estimated that the combined method will allow to transfer the real size of simple objects in 3D with an accuracy of 99.97 % of the actual size of the object. It will also improve the quality of complex surfaces (boundary, glass, mirror) by at least 40–60 %, compared to other existing methods.
Study of the kinetics of carboxymethyl cellulose synthesis in a screw reactor
Authors: Konovalenko Kateryna , Beznosyk Yurii , Bugaieva Liudmyla
Published: December 2021

The object of research is the reactor for the synthesis of carboxymethyl cellulose. An important indicator of the quality of sodium carboxymethyl cellulose, which determines the field of its application, is the degree of polymerization. However, obtaining a product with a specific parameter under industrial conditions is associated with a number of difficulties. Therefore, important research tasks are the development of a mathematical model of the kinetics of carboxymethyl cellulose synthesis, experimental studies to determine the rate constants of synthesis reactions, modeling of a screw reactor for the synthesis of carboxymethyl cellulose, and computer studies.
When studying the kinetics of reactions of carboxymethyl cellulose, one of the possible approaches was to use a quasi-homogeneous model, which is widely used in modeling processes on a catalyst grain. This approach is used to describe and analyze individual stages; however, a number of difficulties arise in heterogeneous reactions of cellulose. In the course of these reactions, the properties of the solid phase change and the processes, respectively, are unsteady in time. The reaction does not take place on the surface of hard particles, but in the entire volume of the fibers. The concentration and reactivity of cellulose hydroxides, water, and products formed during the reaction remain approximately constant; therefore, the use of a quasi-homogeneous model is quite acceptable and does not cause additional mathematical difficulties. As a result of these experiments, according to the obtained integral curves, the method of least squares was used to find the constants. To determine the values of the kinetic constants, an experiment was carried out in an integral isothermal reactor. During the experiments, the degree of substitution of carboxymethyl cellulose and the concentration of free alkali were measured. As a result of numerous implementations of the search task, the values of the constants and activation energies were obtained. This kinetic modeling approach can be used in the synthesis of other cellulose ethers. The rate constant of the synthesis reaction depends on the process conditions. Using the proposed approach to describing the interaction of cellulose with a reagent, the reaction mixture considered as a quasi-homogeneous system can be described using a single-phase flow model.

The object of research is fish culinary products in the jelly pouring of the menu of conceptual restaurants. The subject of research is the consumer characteristics of gelling fish broth for culinary products based on sensory characteristics.
The study used methods for determining the consumer characteristics of fish culinary products based on physical, chemical, aesthetic and sensory analysis. Methods for the preliminary preparation of hydrocolloids as structure-forming agents for the preparation of gelling culinary products with the study of the parameters of the jelly formation process are proposed. The developed ingredient composition of fish culinary products based on low methoxylated pectin and sodium alginate improves the consumer characteristics of the finished dish. This ensures the implementation of strategic decisions in the food industry through the introduction of innovative technologies and the release of products with new consumer and functional properties. It is the new ingredient composition of the fish culinary products in the pouring that opens the priorities in the creation of the wellness products industry with the aim of improving the health of consumers. The active elements of algae are absorbed almost completely through a chemical composition close to that of human plasma. As a result, algae are able to compensate for the lack of elements and contribute to the normalization of metabolism. The use of low-esterified pectin is due to its structure-forming, therapeutic and prophylactic, sorption, antibacterial properties, which are an alternative to antibiotics and synthetic preservatives to prevent bacterial spoilage. The use of dietary supplements based on sodium alginate and pectin in food products provide an adjustable texture with new rheological and functional properties, which have a positive effect on the commodity performance of finished products for promotion on the market of healthy food restaurants.
On the basis of the sensory indicator, rational parameters of the recipe of fish culinary products in jelly pouring were determined to obtain a transparent, stable, homogeneous elastic consistency, which will expand the range of the wellness menu of restaurants of the Wellness concept.

Published: December 2021

Demographic explosion of the early modern society, which constituated the basic material for the Malthusian theory, is a major problem of mankind. Population growth remains high in absolute terms (in 1950 lived on earth only 2.5 million inhabitants in 1970 were 3.2 billion and in 2006 were 6.68 billion people).

As a result of population growth, agriculture, the main segment which provides food resources, can significantly restrict the activities currently being allotted to each man 0.56 ha farm, of which the 0.26 ha arable.

Because scenarios predict a growing population it is required the increasing of current levels of food production more than proportionally with population growth, so as to provide a proper diet for many people.

Experimenting new technology of cultivating maize is an important step forward in order to optimise the yielding capacity if a crop that ranks second among crops cultivated worldwide and first among crops cultivated in Romania.

Using low frequency radiations to stimulate yield and quality in maize allows increases in yield between 10 and 15% compared to the classical cultivation method and an improvement of the quality indicators (protein content increased with 6-11% determining an increase of the protein yield per ha; starch content increased with 7-14%, which also determined an increase of the starch yield per ha; while fat content, another indicator we monitored, increased with 2-6%).
Relationships Between Kernel Physical Properties and Zein Content in Corn Hybrids

Previous research documented that physical properties of corn kernel are related to total zein content, but limited information exists for specific hybrid responses. Therefore, the objective of this research was to determine the relationships between kernel physical properties and zein content in various corn hybrids. Eight commercial corn hybrids (Bc 244, Bc 354, Bc 394, Bc 462, Bc 572, Bc 572, Bc 678 and Pajda) were grown under intensive production management in the growing season of 2009. Kernel physical properties determined were the 1000-kernel weight, bulk density, kernel density, Stenvert hardness parameters (grinding time, total column volume, ratio of coarse to fine particles) and flotation index. For tested hybrids, physical properties ranged 342.6- 446.2 g for 1000-kernel weight, 0.861 - 0.909 kg/L for bulk density, 1.051 - 1.243 g/mL for kernel density, 0 - 30.40 % for flotation index and 1.20 - 2.03 for coarse-to-fine particles ratio. Total zein content ranged from 51.62 to 65.15 g/kg in the whole kernel and from 59.64 to 73.81 % in the crude protein. Hybrid with the lowest zein content in the whole kernel had the highest zein content in crude protein. The total zein content in the crude protein positively correlated with bulk density (r=0.39*) and 1000-kernel weight (0.29*). Positive correlation (r= 0.47**) was found for total zein content and Stenvert coarse-to-fine ratio. However, two hybrids (Bc 678 and Bc 462) that significantly varied for zein content achieved similar kernel hardness properties indicating that factors other than zein content influenced kernel hardness.
