Authors: Mordanov Oleg , Khabadze Zurab , Meremkulov Roman , Mordanova Anastasia 
Published: February 2024

Aim: to evaluate the characteristics of glazed and polished surface during hydrothermal aging using different types of zirconium dioxide.
Materials and Methods. The same standardized samples from different types of zirconium dioxide with a diameter of 10 mm and a height of 1 mm were used for all experiments. These types included Katana (Kuraray Noritake Dental, Tokyo, Japan) HTML (control) UTML, STML, and ZirCAD Prime (Ivoclar Vivadent). Atomic force microscopy (AFM) was used to measure the roughness and to visualize the surface morphology of the samples. The Bruker Innova instrument was used as an atomic force microscope. Image acquisition was carried out in semi-contact mode. The probe sensor was TESP-V2 with a triangular-shaped probe and a tip radius of 7 nm. The scanning area was 50 x 50 μm. Frequency 0.5 Hz. The study of roughness was reduced to the processing of AFM image data. For this purpose, three arbitrary sections were made in the height map channel and the necessary roughness parameters Ra, Rz were calculated using software.
Results. There was an increase in roughness during artificial aging of the control group of glazed surface, Prime group of polished surface, and Prime group of glazed surface. There is a decrease of roughness in the process of artificial aging of the control group of glazed surface, for STML and UTML groups of both glazed and polished surface. In the case of samples of group "polishing" it is possible to observe that roughness is formed by traces of abrasive material. From the results of the study of roughness it can be noted that for the samples of the group "Glaze" roughness is formed mainly by traces of brush or other tools used in the process of glaze application
Conclusion. Artificial aging affects the roughness of the glazed and polished surface of zirconium dioxide with cubic phase predominance depending on the amount of yttrium content.

The most characteristic manifestations of desquamative gingivitis are bright hyperemia, the appearance of blisters of various sizes on the free and attached gum and erosion. This type of lesion can occur in diseases such as lichen planus, pemphigus, systemic lupus erythematosus. Despite the manifesting clinical picture, difficulties arise at the clinical reception in diagnosing both the symptom itself and the underlying disease. All this increases the interest in studying the main and additional clinical signs of specific gum lesions in lichen planus of the oral mucosa. In this paper, the manifestations of the signs of desquamative gingivitis observed by us in various forms of lichen planus are presented in detail, the main and additional signs of specific gingival lesions are highlighted, which make it possible to increase the effectiveness of the primary diagnosis of specific gingival lesions in patients with diseases of the oral mucosa.
Subject of the study. To systematize the main and additional signs of forms of desquamative gingivitis with lichen planus of the oral mucosa.
Purpose of the study. Identify and describe the main and additional clinical signs of forms of desquamative gingivitis in the red lichen planus of the oral mucosa.
Methodology. The analysis of complaints, anamnesis, results of clinical and laboratory examination methods was carried out, photographs of clinical manifestations on the mucous membrane and the red border of the lips of the main and additional signs of a specific lesion of the gum were studied in detail.
Results. The conducted clinical study made it possible to identify and describe in detail the main (bright hyperemia with sharp borders, uneven nature of the lesion, the spread of the process to the gum in the area of missing teeth, etc.) and additional clinical manifestations (papules, blisters, hemorrhages, dryness, epithelial atrophy) of desquamative gingivitis in all forms of red lichen planus of the oral mucosa.

Published: February 2024

Background data. A clinical case of brain abscess that occurred as a complication of chronic odontogenic osteomyelitis of the mandible on the background of a severe form of dentophobia.
Subject. Chronic periodontitis is a possible cause of the development of potentially dangerous complications such as mediastinitis, thrombophlebitis, brain abscess, etc. Most often these complications arise due to untimely seeking medical help because of fear of dental intervention, the extreme manifestation of which is dentophobia. It is also known that odontogenic cause of cerebral abscess is foci of infection localised in the region of the maxilla.
Objective: to study and describe a case of brain abscess, which occurred as a complication of chronic odontogenic osteomyelitis of the mandible on the background of a severe form of dentophobia.
Materials and Methods. We analysed the medical records of a patient with odontogenic brain abscess resulting from a complication of chronic odontogenic osteomyelitis of the mandible on the background of severe dentophobia.
Results. A patient with brain abscess developed as a result of exacerbation of chronic odontogenic osteomyelitis of the lower jaw was urgently hospitalised to the maxillofacial surgery department of the Tyumen General Hospital No. 2.
From the anamnesis it is known that during 1.5 years the patient had repeatedly applied to the Tyumen General Hospital No. 2 for chronic apical periodontitis, however, he did not agree to surgical treatment because of fear of dental intervention. Further, despite the deterioration of his condition, he twice refused hospitalisation.
During his stay in hospital, the patient received surgical and intensive medical care. After treatment, he was discharged with residual neurological consequences. Psychocorrection of dentophobia was prescribed.
Conclusions. 1. The cause of brain abscess may be an odontogenic inflammatory process localised in the mandible. 2. Dentophobia leads to untimely medical care and may be the cause of serious complications.

Published: February 2024

The productivity of agricultural crops is determined by the choice of varieties, planting material, the optimal time of sowing and planting depending on the climatic conditions of the region, the use of organic and mineral fertilizers, and care methods. Planting material plays an important role in the growth and development of onions and the formation of yield. Onions are very demanding in terms of nutrition, this is due to the length of the growing season, growth rates and poorly developed root system. To obtain high and high-quality onion yields, it is necessary to use fertilizers in an accessible form. Water-soluble complex mineral fertilizers quickly and evenly penetrate deep into the soil. Fertilizers improve the growth and development of plants, regulating nutrition processes, increase the yield and quality of the resulting products. As a result of many years of research, it was found that optimizing the mineral nutrition of onions through the use of fertilizers in active form provides a significant increase in the yield of onions. A comparative assessment of the productivity of onions when grown from sets of different fractions using water-soluble complex mineral fertilizers in the conditions of the Udmurt Republic has been little studied.Materials and methods. The purpose of the research: to improve the technology of cultivating onions depending on the fraction of the set and fertilizing with water-soluble complex mineral fertilizers. In 2020–2021 On onions of the Stuttgarter Riesen variety, a two-factor experiment was carried out to study the effect of fertilizing with Aquarin and Rastvorin fertilizers when using different fractions of sets for planting. The studies were carried out using generally accepted methods.Results and its discussion. In the Udmurt Republic, the optimal for planting Stuttgarten Riesen onions is the medium and large fraction of the set, and the positive effect of water-soluble complex mineral fertilizers Aquarin and Rastvorin on the yield and its structure has been revealed. However, it is more economically profitable to use the fine fraction of sets when growing onions.

Published: February 2024

Relevance. Powdery mildew is one of the most common and harmful diseases of cucumber (Cucumis sativus L.) in open and protected ground. Moreover, in the closed ground, the harmfulness is higher than in the field. The yield of cucumber, due to the defeat of plants by powdery mildew, decreases by 30-50%, and in some cases by more than 70%. The creation of modern cucumber hybrids is impossible without the constant involvement in the breeding process of new sources of economically useful traits, including resistance to real powdery mildew. It is very important to combine in one line both a high degree of parthenocarpy, and the female type of flowering, and resistance to the most harmful diseases. We tried to solve this problem in our work.Materials and methods. The experience was laid in 2018-2022 in the Odintsovo district of the Moscow region on the basis of the head institution of the Federal State Budgetary Scientific Institution Federal Scientific Vegetable Center (FSBSI FSVC) in the conditions of a spring ground greenhouse of the Block type, on a natural infectious background. On the basis of the laboratory of breeding and seed production of pumpkin crops, 27 collectible and about 50 breeding samples of parthenocarpic cucumber were studied. The article presents an assessment of the resistance to this powdery mildew of 36 of the most aligned and most valuable cucumber breeding samples in terms of a complex of economically useful features. 2-3 families, 6 plants in each, were evaluated for each sample for 2 years. During the entire growing season, the intensity of powdery mildew damage was assessed on a four-point scale and the spread of the disease in %.Results. Among the collection samples of cucumber, on a natural infectious background, two hybrids of the agrofirm BEJO ZADEN B.V. were not affected by powdery mildew: Amur 1801 F1, Artist F1, a hybrid without a name of the agrofirm MONSANTO HOLLAND B.V., conventionally named – Semenis F1 and hybrid Kibria F1 of the agrofirm RIJK ZWAAN. To a small extent, less than one point, they were amazed: Orpheus F1, Merengue F1, Marinda F1, Masha F1, Othello F1, List F1, Adam F1, SV 4097 F1 and Krasotka F1. 11cucumber breeding samples selected in previous years of research on a complex of economically useful signs that were not affected by this disease during 2 years of research were identified. Work will continue to evaluate these lines for resistance to real powdery mildew on an artificial infectious background.

Objective: The aim of this study is to evaluate the correlation between the incidence case/death rate of coronavirus disease 2019 (COVID-19) and some variables of the countries. Methods: This research is an Ecological study. We analyzed the association of COVID‐19 incidence of cases/deaths with population rates over 65, Gini index, GDP per capita (current US$), burden of disease (DALYs-2019), literacy rate of over 15 years old, Coefficient of Variation (CV) of caloric intake, prevalence of obesity among adults, total COVID-19 vaccine doses administered per 100 people, total test (per 1M). Furthermore, we analyzed the data on COVID-19 incidence of cases/death in the cross-sectionally for three periods: Alpha-Beta-Gamma, Delta and Omicron periods. Spearman correlation test was used for statistical analysis. Results: Positive correlations were found in COVID-19 cumulative incidence of cases/deaths (per 1M), and population rates over 65, GDP (per capita), literacy rate of over 15 years old, prevalence of obesity among adults, total COVID-19 vaccine doses administered per 100 people. On the other hand, negative correlation was found with DALYs, Coefficient of Variation (CV) of caloric intake and Gini index. When the variant periods of COVID-19 were examined respectively (Alpha-Beta-Gamma, Delta and Omicron), the positive correlation and the negative correlation were further increased during the Omicron period. Conclusion: It is recommended to consider the demographic and socioeconomic characteristics of the countries as well as the characteristics of the disease agent for the prevention and control of a possible pandemic in the future.

AN ASSESSMENT OF THE IMPACT OF BORDER CLOSURE BY THE NIGERIA GOVERNMENT ON REGIONAL INTEGRATION IN THE WEST AFRICA REGION
Authors: Ogundare Yemi , Edun Abdulkareem Jimoh , Ayinde Salihu Mosadioluwa 
Published: February 2024

Abstract
Nigeria is the acclaimed giant of Africa in specific ramifications. The country is bordered by four African countries namely Cameroon, Chad, Benin, and Niger, and emphatically the hub-nub of economic survival of many African nations such as Togo and Ghana. However, Nigeria’s government recently announced the closure of its borders with these neighboring countries albeit, temporarily, and cited illegal importation of goods and services from these countries which has a consequential damaging effect on her economy. This paper interrogates the reasons and consequences of Nigeria’s Government’s action on border relations with neighboring countries. Adopting the descriptive design method, the research work relied heavily on secondary sources of data collection. Proximate stakeholders such as importers and exporters, Nigerian farmers, and relevant government agencies on border control were also interacted with. Using protectionist theory to analyze trends of actions, the theory argues that protectionist trade policies will always lead to an improved economic result. Findings reveal that despite short-run socio-political and economic gains, protectionism negates the principle of globalization and free trade principles which both the Economic Community of West African States(ECOWAS) and Africa Union(AU) promote among its member states including Nigeria that are signatories to the free trade protocols. The paper recommends among others, that the Nigeria Government should address her internal challenges within its border security apparatus to avert the double jeopardy of violating border relations principles and creating a trade war with her neighbors
