In the 1990s and 2000s, several countries underwent important and significant changes in their universities. Likewise, in Brazil, due to the implementation of several government programs, there was an expansion of higher education and made possible a greater access to graduation. At the beginning of 2020, the world was threatened by COVID-19, several restrictive measures were implemented by government and private entities to contain the spread of the disease. In this way, Brazilian educational institutions were forced to temporarily suspend their in-person activities in order to promote social distancing. They soon found themselves in the challenge of implementing teaching methodological changes to continue the activities, in an emergency and remote way, since the outbreak of the disease did not stop within months and there was no prediction of when it would occur. This study aims to evaluate the performance of students at the Federal University of São João del-Rei at the Sete Lagoas campus in the discipline of Organic Chemistry, in the Food Engineering, Agronomic Engineering, Forestry Engineering and Interdisciplinary Biosystems courses in the two semesters of 2018 with 223 students and during the two semesters of the first year of emergency remote teaching (2020) with 337 students, drawing a parallel between them in order to raise the impacts of remote teaching for the discipline of Organic Chemistry.

A cana-de-açúcar é uma cultura de grande relevância econômica para o Brasil. Nas últimas décadas, a preocupação ambiental que afeta os países do primeiro mundo se tornou uma tendência mundial, e que acabou por ser transferida ao consumo de alimentos e a maneira como estes são originados. No Brasil, os agricultores rurais familiares são responsáveis por 90% da agricultura orgânica, no qual os produtos orgânicos se tornam um meio rentável para as empresas, aliado a uma escolha saudável para os usuários. No entanto, para se ter ingresso nesse segmento produtivo, os pequenos produtores que cultivam e comercializam produtos orgânicos precisam obedecer a diversos requisitos legais, como, por exemplo, a certificação (Lei 10.831,2003) e o cadastro no MAPA. Nesse sentido, esse estudo objetivou revisar os sistemas de produção de cana-de-açúcar visando a produção de açúcar orgânico certificado, aprofundando o conhecimento no que tange os procedimentos para essa produção. Através dos dados revisados, é notório o crescimento da produção de açúcar orgânico no Brasil, e que sua oferta, tanto quando se leva em consideração a questão geográfica quanto da produção, se concentra especialmente no Centro-Sul do Brasil, atendendo à crescente demanda do mercado interno e externo.
RESTORATION OF ENDODONTICALLY TREATED TOOTH
Authors: S Nikesh , A Nivetha , Kadandale Sadasiva , Ramachandran Anupama
Published: November 2022

A successful endodontic treatment depends on endodontic treatment as well as post endodontically restoring the lost tooth structure2 . Compared to vital teeth, root canal-treated teeth will be more prone to biomechanical problems. Post-core treatments are often used in dentistry to prevent fracture of the remaining dental tissues in crown treatments and to support the final restorations in root canal-treated teeth, especially those with extensive loss of tooth structure. An ideal post should dissipate the occlusal load acting on the tooth uniformly. In the event of a retreatment the post must be easily removeable.

Published: November 2022

3D printing or additive manufacturing is the forerunner in today’s digital dentistry. Charles Hull devised the concept of 3D printing in dentistry in early 1980’s. 3D printing involves addition of layers, one over another, to form an object. (1) Rapid prototyping, layered manufacturing or solid-free form fabrication are various other terms used that refer to additive manufacturing. Additive manufacturing has been in use in dentistry since early 1980’s and has constantly evolved from the first 3D printers in 1984, up to the recent bioprinters capable of printing specific tissues and organs.

Published: November 2022

Endodontic treatment's primary purpose is to treat pulpal and periapical pathosis (1).For dental health care practitioners, especially endodontic experts, an inflammatory apical or peri-radicular lesion in an already obturated tooth that persists or progresses is a serious concern. According to different research populations, this post-treatment apical periodontitis/post endodontic diseases prevalence varies from 16 to 65 percent (2). The presence of microorganisms throughout the root canal system and/or in the apical region has been suggested as the major reason, while other factors such as presence of cysts, cystic components like cholestrol crystals, persistent inflammatory activities were also been associated (2). Nonsurgical or surgical retreatment is always the primary line of treatment (3). Retreatment and periapical surgery have been suggested as treatment modalities with different levels of success rates (4). Intentional replantation is advocated as an alternative way for treating post-endodontic pathology or failed non-surgical retreatment and also when we face a difficulty in surgically approaching the site, need to not damage the innate anatomical structures, or to improve operational efficacy(5).

Published: November 2022

Aesthetics has evolved over the years and it is still evolving. Orthodontic correction of the teeth and the jaws are deemed to be the only modality for esthetic correction. A variety of orthodontic techniques like clear aligners are being used in daily practice to achieve this. But the irony is, that there is no clear evidence for the etiology of malocclusion. The concepts regarding the etiology of malocclusion are based on philosophies that have been accepted widely. Mewing is a technique that dictates for placement of the tongue against the palate with lips closed to achieve an ideal jaw alignment. This paper aims in evaluating and assessing the role of orthotropics as a potential treatment modality for improving jaw alignment and facial aesthetics.

Periodontitis is intricate & multi-factorial lesion. It is characterized by a group of inflammatory conditions in the periodontium which is caused by bacteria. Chronic inflammation is precise by B and T cells by the initiation in cytokine secretion, then osteoclastogenesis is modulated. The objective of the article briefly reviews the recent research and the consequence in B cell & T lymphocytes subsets, and the expression of cytokine seen in the morbific of the periodontitis. Gingival homeostasis is maintained by T reg (T regulatory), CD8+ T, and tissue-resident γδ, T cells plays a vital role in gingival hemostasis. Clinically healthy periodontium has a low percentage of memory B cells, evade bone damage due to subclinical inflammation. The RANKL -dependent method makes an alveolar bone loss and causes periodontitis. Stimulation of T and B lymphocytes subunits is one that causes either the seditious lesion will alleviate in chronic gingivitis or it may advance to a tissue destructive periodontitis.

Published: November 2022

An epithelial-mesenchymal transition (EMT) is a biologic process that allows a polarized epithelial cell, which normally interacts with basement membrane via its basal surface, to undergo multiple biochemical changes that enable it to assume a mesenchymal cell phenotype, which includes enhanced migratory capacity, invasiveness, elevated resistance to apoptosis, and greatly increased production of ECM components”. EMT was classified into three types, based on its activity in the human body at varied events during: 1) Embryogenesis, 2) Physiological Wound healing and Fibrosis, 3) Cancer Progression. There are numerous molecular signaling pathways involved in EMT during cancer progression & metastasis. Numerous therapeutic targets have been developed against these altered EMT signaling pathways as a treatment modality.

Published: November 2022

Histopathological examination is one of the chief investigations done for better diagnosis. The tissue has to undergo a series of steps called tissue processing. The initial and significant action is fixation. Proper fixation is one of the prime factors while considering histopathology. Formalin has been used as a fixative over many years. Recent studies proved that formalin causes irritation and is carcinogenic. So we have to switch over to another feasible alternative which is non-hazardous and eco- friendly. Since honey has antibacterial and antioxidant properties, studies proved that it could be a fixative. Likewise, jaggery local anaesthetics can be used as a fixative. Under this topic, we will be seeing all the basic principles of fixation, ideal fixative, the side effects of formalin, the things that serve as alternatives as a fixative and how they fix the tissues.

Published: November 2022

The major objective behind the endodontic therapy is to primarily decrease the microbial load from the infectious root canal system by meticulous bio-mechanical preparation followed by a fluid impervious obturation in order to offer a favourable environment for the periapical healing. Every clinical procedure while performing endodontic therapy requires maximum flawlessness, few of the examples are estimation of working length accurately, meticulous biomechanical preparation with sufficient usage of intracanal irrigants and medicaments, and with the advanced magnifying aids like dental loupes and microscopes. Despite performing the endodontic therapy diligently, the post-endodontic pain prevalence is not uncommon and is fairly high. The post-endodontic pain is an unpleasing sensation yet a common occurrence in the clinical grounds that greatly affects the standard of relationship between the patients and doctor.

Published: November 2022

Mycophenolate mofetil (MMF) is a potent immunosuppressive agent frequently used to prevent acute graft rejection in kidney transplant recipient. It has various adverse effects such as leukopenia, anemia, and diarrhea. However, oral ulcers are rarely reported. We present a case of a living-donor kidney transplant recipient who developed multiple oral ulcers during high dose MMF therapy. A 24-year-old female with end-stage renal failure due to lupus nephritis underwent kidney transplantation from a CMV-positive living donor in August 2021 complained of painful oral ulcers which developed 2 months after kidney transplantation. As the ulcers grew larger and more painful, the patient began to have odynophagia and symptoms worsened. The immunosuppressive maintenance regimen comprised of steroid, tacrolimus and MMF. At the beginning, the internist suspected that the oral ulcers were caused by CMV infection. Despite the use of valgancyclovir for 4 months, the oral ulcers persisted and showed no improvement. On physical examination, multiple deep and large ulcers on the gingiva, buccal and labial mucosa were noted. The ulcers characteristics, minimal response to valgancyclovir therapy, and the absence of other infection possibly caused oral ulcers led the oral medicine specialist to the diagnosis of high dose MMF-induced oral ulcers. MMF was replaced with enteric-coated mycophenolate sodium at lower dose and the patient was instructed to use dexamethason swish and spit thrice a day, oral ulcers showed improvement after 5 days. Oral ulcers in kidney transplant patients should be carefully evaluated, and if MMF is suspected as the cause, MMF should be reduced or another therapeutic option is considered.

Authors: Srinivasan Dr. Daya , Narayan Dr. Shoba
Published: November 2022

Dental decay is one of the paediatric disorders requiring early intervention and can lead to tooth loss if not treated. Antimicrobial medicines work by altering the nature of pathogenic microorganisms in dental biofilms to reduce cariogenic activity. When fluoride is mixed with silver, which has an antibacterial effect, its antimicrobial efficiency is boosted. Silver diamine Fluoride has been shown to aid in the prevention of tooth decay, with the only drawback being an unsightly black discoloration. Silver nanoparticles with an appropriate surface range and a huge proportion of surface atoms have attracted attention due to their distinguishing characteristics. Although Silver diamine Fluoride has altered dentin collagen shape and Nano silver fluoride has normal collagen fibrils, both show intrafibrillar remineralization. Nano silver fluoride is a topical agent which can be safely, and cost-effectively applied to children for treating dental caries.

The article is devoted to the analysis of the functioning of the construction industry in Ukraine. The aim of the article is to analyze and assess the current state of the construction industry of Ukraine, the financing of state housing programs and compare on this basis the domestic construction sector with European trends in real estate. The study found that the biggest decline in 2020 was in the housing construction sector, while the volume of construction of non-residential buildings has not changed, and the construction of engineering structures is even ahead of the pace of 2019. It is established that in 2020 the trend of reducing funding for public housing programs, including the program «Mortgage Available 7%», launched in March 2021. It was established that in most EU countries the mortgage rate does not exceed 3%, which is much lower than the preferential 7% in Ukraine. It was found that industry expects rising prices for construction products, coinciding with the European trend housing prices. Thus, the pandemic 2020 posed several challenges to the construction industry, but also opened new prospects for further development of the industry: new materials, 3D printing, information modeling technology, decarbonization, energy efficiency. And Ukraine has every chance not to stay away from the latest trends in the construction industry. Domestic construction companies do not stay away from the latest technological trends in real estate. Thus, changes to the Procedure for developing project documentation for the construction of facilities that allow the use of VIM technology have come into force. This opens extremely wide opportunities for designers. In Ukraine, there are projects where the principle of mixed-use development is implemented – a combination of residential, commercial, and industrial sectors in one space, energy-efficient technologies are increasingly used, and some new buildings are certified according to BREEAM, LEED and ActiveHouse standards, combining environmental friendliness, energy saving and comfort.

Authors: ROMANENKO Serhii
Published: November 2022

Modern research shows that sports and health activities are an essential system-forming element of socio-economic systems, the development of which has a multiplier effect on a wide range of spheres of social and economic life. The purpose of the article is to analyze the financial and economic aspects of developing sports and health in Ukraine. The financial and economic factors of developing the sports and health sphere in Ukraine are analyzed, as well as the reduction in funding for physical education and sports in Ukraine. It is determined that for the period 2015-2020, the total expenditures for the development of physical activities and sports decreased by 81.9%, and funding for the industry from the state budget decreased by 92.3%. This reduction in spending is due to the deteriorating general economic situation and the use of funds to finance more pressing issues from the viewpoint of government officials, namely, funding the army and national security, health, transport infrastructure development, etc. In 2015, the share of the public budget structure of financial sources was 23%, and local and regional budgets were 46.1%. In 2020, the situation changed significantly, and the share of the state budget decreased to 10%, and local budgets increased to 87.7%. This redistribution of funding sources is primarily related to the implementation of the decentralization reform, in which funding for a significant part of the humanitarian sphere has moved to the level of district budgets and local communities. As a result of the reform, only for the period 2018-2020, the share of financing of physical culture and sports in the structure of expenditures from the budgets of territorial communities increased from 3.4% to 42.2%. The mechanism of influence of sports and health-improving activity on the national economy is given. It is emphasized that an essential factor in developing any sector of the national economy is to ensure the appropriate level of funding and efficient allocation of financial resources according to the needs and objectives. It is determined that the primary sources of development of sports and physical activities, depending on the nature of activity, are the funds of state and local budgets, as well as local communities, sponsors and international organizations, funds of private business, and the population.

Published: November 2022

The article considers approaches to the analysis of risk factors during innovative transformations. It was established that a qualified examination of the financial indicators of innovative projects at the stage of the enterprise preparation for technological rehabilitation allows to evaluate them from the viewpoint of investment attractiveness, taking into account the most important factors that have a well-founded probabilistic assessment. The division of factors that influence the complex of relationships in the context of risk analysis of innovative transformations into factors that directly influence the process of forecasting and preparation for the implementation of innovative transformations and factors that influence the effectiveness of the technological rehabilitation process of production is substantiated. It is outlined that during the implementation of innovative projects, the number of risk factors is quite large, due to which the degree of their influence is random. In any attempt to take into account the influence of all factors, specialists have to face the extremely difficult problem of considering the degree of their influence at several levels of management, because even in the case of a simple hierarchical structure, the number of combinations of the influence factors increases sharply. It is proven that the main task of the analysis of the influence factor should be, first of all, an attempt to limit the number of possible combinations of factors that should be analyzed or considered when finding the objective decision function. It was determined that the key criteria for making investment decisions in the context of innovative transformations are: lack of more profitable alternatives; minimizing risks of losses, in particular, from inflation; minimization of the payback period; relative cheapness of the project; ensuring the stability of cash receipts; high profitability, taking into account discounting.

DETERMINATION OF THE SHAPE OF DEFORMED WORKING SURFACES IN RUBBER-METAL SLIDING BEARINGS
Authors: SVIRGUN Olha , SVIRGUN Valentyn , ANTOSHCHENKOV Roman , BRYK Ivan
Published: November 2022

In this work, the attempt is made to investigate the deformation types of the bearing surfaces, they have a surface made of a material such as rubber, which is lubricated with water. Rubber bearings are successfully used in cases where the friction unit must be in water or another liquid medium. Along with performing their direct functions, rubber bearings can dampen vibration, noise and some shaft misalignments. The essential feature of bearings with a surface made of materials such as rubber is the unusually low elasticity modulus of the rubber coating, which is tens of thousands of times less than the elasticity modulus of metal surfaces. Water, as a lubricant, also differs from mineral oils in much less dynamic viscosity and has a slightly higher heat capacity and thermal conductivity. The significantly lower ability of water to create thin and strong adsorbed layers on the rubbing surfaces, which depend on the nature of the lubricant, surfaces and the nature of the interaction of oil molecules and a solid. The low dynamic viscosity of water does not allow, under normal operating conditions, hydrodynamic bearings to provide the required minimum thickness of the lubricating layer, which makes it possible to compensate with a margin for possible errors in manufacturing, installation, force and temperature deformations. By the joint solution of the equations of hydrodynamics and equations of the theory of elasticity, taking into account the incompressibility of rubber, certain forms of deformed working surfaces in plain bearings with a working surface made of a material such as rubber were considered. This makes it possible to solve the problems of determining the volumetric deformation of the bearing, assessing the total displacements of the shaft and determining the loads that fall on individual bearing support parts. As a theoretical basis, Newton's second law and the law of conservation of mass are used. Methods of the theory of elasticity are used to assess the deformations of elastic surfaces. When rubber is loaded, there are three types of deformations: elastic, highly elastic and viscous. Under repeated loading, good repeatability of the deformation values is observed.
Key words: rubber-metal bearing, water lubrication, forms of deformed working surfaces, theory of elasticity.

Published: November 2022

Introduction. The study of rural areas is an important mission in the development of socio-economic systems of the state and its territories. Transformational changes that have taken place in the process of reforming the national economy and as a result of changes in the administrative-territorial structure of the country require the determination of the location of each component of its territories. Of particular importance is the study of rural areas, where the agricultural sector has a place in the vector of development. The latter determines the standard of living of the population of rural areas and forms a significant share and role in the system of socio-economic development of the state and its regions.
The purpose of this article is to research of theoretical and methodological bases of formation of rural territories and their place in the system of social and economic development of the state and regions.
Results. Studies have shown that the primary link, the center of rural areas is a rural settlement. Therefore, in our opinion, the key criteria for determining the rural area are administrative-territorial and self-governing. Thus, a rural area is one that is within the jurisdiction of territorial communities of rural (urban) settlements and includes agricultural and non-agricultural lands. This approach has a normative basis – the Law of Ukraine "On Local Self-Government in Ukraine" and the Law of Ukraine "On Voluntary Association of Territorial Communities".
Conclusions. The importance of rural areas in the socio-economic development of the country is not limited to social factors. After all, despite the high potential for the development of non-agricultural activities in the future, currently rural areas are the center of agricultural production, which is a strategic sector of the national economy. The agrarian economy performs the most important function in the system of ensuring socio-economic stability of rural development of the state and its regions.

ANALYSIS OF INVESTMENT ATTRACTIVENESS IMPACT ON THE INCREASE OF THE REGION COMPETITIVENESS LEVEL
Authors: BUSHYNSKY Yevhen
Published: November 2022

It is substantiated that the concentration of economic activity determines investment attractiveness, that is why there are bilateral relations between these two economic categories, ie attractiveness determines concentration, and concentration means attractiveness. The essence of the concept of "investment attractiveness" has been studied, which allowed to establish a close relationship with the development potential of the region. It is determined that due to the multidimensionality of economic categories "investment attractiveness" and "potential of regional development", they partially describe the same problem, ie opportunities for regional development. It is proposed to define investment attractiveness as the probability or scale of investments, with the potential of development as a resource and the degree of use of factors that determine development at the regional level, so it can be argued that investment attractiveness is a significant incentive to develop its potential. Since investment attractiveness is identified with the competitiveness or competitive advantages of the region, it is outlined that regional competitiveness is a derivative of investment attractiveness, and through the process of competition it also affects its final dimension. It is determined that investment attractiveness is a certain way of perceiving space, which in most cases means a relatively objective assessment of the level of socio-economic development of regions according to selected criteria and weights, thus, it is calculated as a synthetic value. It is established that the regions compete on the level of their investment attractiveness in attracting investments and creating development opportunities, as these are the factors that determine their further development opportunities and level of socio-economic development. Therefore, a relatively higher attractiveness for the region means a greater likelihood of achieving the goals of competition, which is to improve living standards and expressed in the growth of specific areas of socio-economic life, particularly through investment inflows or domestic investment activities.
Keywords: investment attractiveness, competitiveness, region, evaluation.
Used (Lived) versus Offered (Plain) densities of human settlement in space: An instance of the probabilistic consumption model
Authors: Leurent Fabien
Published: November 2022

To people living in areas, the denser is the area, the more numerous are the opportunities of interpersonal and social interaction, of employment and of amenities of all kinds. The spatial density of human settlement is basically studied according to places, that is, area weighted. The notion of population-weighted density, or lived density, puts human density in the perspective of the people that experience it. Considering, respectively, the land units and the people as statistical populations of their own, the article provides a probabilistic model of human density in a geographical space, as a random variable in each statistical population, with specific probability density functions (PDFs) and cumulative distribution functions. The PDF of lived, “Used density” is derived from that of the plain, “Offered density” through a consumption model: Thus, their relationship is a specific instance of a well-established probabilistic model. The average used density is systematically larger than its offered counterpart: The ratio amounts to one plus the squared coefficient of variation of offered density. The relation between the two statistical distributions is illustrated using a Lorenz curve; the associated Gini index constitutes an indicator of population heterogeneity in a geographical space. A case of France’s population as of 2019 is studied to demonstrate the methodology.
Significant energy savings in the beet sugar industry to reach the decarbonization goals
Authors: Schellen Sébastien , Couplet Vincent
Published: November 2022

Biomass-based energy (solid fuel or biogas) and green electricity take a growing share in today’s low-carbon/carbon-free energy sources. Contrary to industries with high-temperature energy consumption (e.g. steel or cement industries), the sugar industry uses relatively low-temperature energy (except for milk of lime production). To reach low-carbon/carbon-free reduction, the sugar industry will have to re-design its complete energetic scheme. The panorama of solutions answering the aforementioned questions are reviewed. Among these solutions, the optimization of the process by using existing well-known technologies is the 1st option: mechanical vapour re-compressors (MVR), heat pump, cogeneration technologies, by-product anaerobic digestion, etc.

Combining these solutions will support the sugar industry to decrease significantly its specific energy consumption. As a reference, today’s sugar factories have a specific consumption between 900 to 1200 kWh of primary energy per tonne of sugar. A target for the future is to decrease the specific primary energy consumption to 620 kWh per tonne of sugar (without pulp drying). This new benchmark could be even improved in the case of using low-carbon electricity imported from the grid. How far could one go into the decarbonization of beets sugar factories? Is the objective of having net-zero emissions for sugar production realistic?
ОСОБЛИВОСТІ ПРОТЕЇНОВОГО ЖИВЛЕННЯ ПЕРЕПЕЛІВ

Зазначається, що протеїнове живлення перепелів визначається потребою у сирому протеїні та незамінних амінокислотах, необхідних для підтримання життєдіяльності та утворення продукції. Потреба у протеїні та амінокислотах молодняку перепелів залежить від віку, живої маси та величини середньодобового приросту, дорослих перепелів – від яєчної продуктивності, маси яєць і амінокислотного складу яєчного протеїну.

Амінокислотний склад корму повинен відповідати потребі перепелів у незамінних амінокислотах, оскільки як нестача, так і надлишок деяких з них, а також надлишок протеїну взагалі негативно впливають на їх продуктивність.

Вирішальну роль у продуктивності сільськогосподарської птиці відіграють кількість протеїну, його якість або біологічна цінність, яку встановлюють за вмістом незамінних, або критичних амінокислот.

Предметом щодо вибору тематики досліджень є актуальність проблеми протеїнового живлення перепелів.

Метою дослідження є вивчення впливу концентрації лізину та співвідношення незамінних амінокислот у складі кормів раціону на продуктивні якості перепелів.

Основними параметрами щодо визначення продуктивних якостей ремонтного молодняку перепелів і перепелів-бройлерів є зміна живої маси та ефективність використання корму, дорослих перепелів – кількість яєць, їх маса і склад, витрати комбікорму на виробництво 10 штук яєць

На даний період проводиться робота щодо організації та проведення експериментальних досліджень на ремонтному молодняку перепелів 1-4 тижнів, ремонтному молодняку 5-6 тижнів та на дорослих перепелах.

У результаті комплексної оцінки сучасного стану поголів’я великої рогатої худоба у господарствах усіх категорій в умовах України в розрізі останніх трьох років (2020-2022рр) встановлено тенденцію до стрімкого зниження поголів’я в межах 7,1-8,0 % за рік. Аналіз групування підприємств за кількістю великої рогатої худоби на 01.01.2022 року показує, що скотарством займалися 1792 підприємства, в яких налічувалось 1003,4 тис. голів. Подальший розвиток галузі молочного скотарства повинен відбуватися за рахунок: збільшення поголів’я корів при використанні сексованої спермопродукції; цілорічне утримання худоби на вигульних майданчиках, створення органічних ферм.
