Reactive Gingival Lesions, Investigations, And Treatment Modalities: Review Article
Authors: Al-Qahtani Mashael
Published: November 2022

Background and Objectives: Reactive gingival lesions (RGLs) are benign solitary swellings frequently responding to chronic inflammation of gingiva precipitated by local irritation. The research article was designed to discuss clinical and pathological features, and treatment options of RGLs. These lesions are generally clinically similar but histologically different. Various treatment modalities have been used, including surgical blade excision, laser surgical techniques, electrosurgery and cryosurgery. Laser surgeries present more benefits, especially for the hemorrhagic and vascularized lesions in comparison to others. Conclusions: The incidence of RGLs are secondary precipitated to tissue damage and local irritating factors which are like benign rather than malignant masses. Clinical and histological investigations are designated to classify the nature of RGLs. Improvement of oral health, besides complete removal of local irritants through professional periodic care and maintaining oral cleaning measures, is necessary to avoid the recurrence of these lesions.

Objectives: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is generally asymptomatic in children but is still contagious. This study estimated the prevalence of asymptomatic SARS-CoV-2 infection in pediatric surgical patients in a tertiary hospital in Makkah city. Methods: A cross-sectional study was conducted involving children less than 18 years of age who were scheduled for surgical procedures under sedation or general anesthesia at the Security Forces Hospital in Makkah (SFHM) between August 1, 2020, and August 31, 2021. Before admission, each patient was screened for symptoms of SARS-CoV-2 and subsequently categorized as a low or high-risk patient. Asymptomatic, low-risk patients underwent nasopharyngeal swab via polymerase chain reaction (PCR) to detect SARS-CoV-2 infection. Results: A total of 497 asymptomatic pediatric patients were included in this study. The overall prevalence of SARS-CoV-2 positive cases was 1.4%. About 66% of the sample patients were aged eight or less, 66% were males, 76% had elective surgery, and 79% had surgery with general anesthesia. Conclusion: Screening for SARS-CoV-2 without swabbing did not appear to exclude all positive cases.

Churn Prediction and Prevention for OTT/Tele- Communication
Authors: Shinde Aniket
Published: November 2022

Customers are becoming more drawn to the quality of service (QoS) offered by businesses in the present. However, the present day shows greater rivalry in offering clients technologically cutting-edge QoS. However, effective customer relationship management systems may help the organization attract new clients, preserve client connections, and enhance client retention by generating more revenue for the company's operations. Churners have always been a major problem for every business that offers services. Churning drives up a company's expenses while also lowering its profit margin. However, it is possible to forecast if a consumer wishes to cancel service using predictive analysis based on historical service usage, service performance, expenditure, and other behavioral patterns. The problem with churn analysis is that it can reveal unnecessary information when used on databases that are combined by a company that owns confidential information.

Published: November 2022

Evolution leads to innovation to achieve a sustainable environment we need to build a safe ecosystem. Agriculture is an important sector of any economy. Artificial intelligence has been proven to solve many problems that prevent crop failure. The production of any crop depends on various parameters that may be affected by sudden changes in climatic conditions. Unpredictable natural changes result in variations in production yield. Natural parameters such as wind, temperature, climate as well as humidity and more factors affect a lot of farming. Machine learning is used for many purposes to measure the risk factors involved before sowing any crop. The machine helps in decision-making and analysing factors. The Internet of things executed with embedded systems and sensors helps with the evaluation of trends based on real-time data and real-time monitoring. Historical trends combined with technology and real-time analysis helps farmers in choosing suitable crop for maximum and profitable crop production and yield. Technological development is also resulting in increasing agribusiness and modern agriculture. Keywords— Machine Learning; Artificial Intelligence; Internet of things

SMART PARKING SYSTEM BASED ON RFID
Authors: J Dr. Niresh
Published: November 2022

In the modern world with about a billion vehicles present around the globe, and being in a densely populated country like India creates the need for an efficient parking system and with world advancing towards automation, there is also a need for an automated parking system. Mainly the problem of parking arises in big cities and this causes problems like traffic congestion, driver frustration & air pollution, etc. The issue mainly arises from not knowing whether the parking spaces is available at any given point of time. Even if known, many vehicles may be competing for limited parking spaces causing severe traffic congestions. Even there are problems that can be caused with regards to the parking management. It may be difficult for the parking management to organise the parking of the vehicles in an orderly manner. Thus we are trying to resolve the problems stated by developing an RFID based smart parking system that monitors the availability of idle parking slots and guides the vehicle to the nearest such slot by sending a message to the mobile number registered in the vehicle’s RFID. The proposed system uses infrared transmitter-receiver pairs that remotely communicate the status of parking occupancy to the Arduino UNO microcontroller and displays the vacant slots on the display at the entrance of the parking so that the user gets to know the availability /unavailability of parking space prior to his/her entry into the parking place. Implementation involves minimal human interaction and provides a seamless parking experience thereby reducing a lot of time wasted by the user in parking his/her vehicle. Key Words: Parking System, RFID, Arduino UNO

Vegetation cover and spatial distribution of small mammals in the conditions of woodland large city park (Nizhny Novgorod)
Authors: Boryakova Elena Evgenievna
Published: November 2022

The paper is devoted to the study of ecological connectivity vegetation cover and microtine rodents spatial distribution in the conditions of the Nizhny Novgorod woodland park. The oak forest of National Research Lobachevsky State University of Nizhny Novgorod Botanical Garden with partial anthropogenic transformation was chosen as a site of the study. We used five various plant communities represented by linden trees. The dominant in all ecosystems on the test areas is the red vole (73%), the codominant is the pygmy wood mouse (21%). The yellow-necked mouse has been observed only in several communities. It has been revealed that a decrease in the biodiversity of plant communities due to an increase in the degree of individual species dominance marked by BergerParker index doesnt entail significant negative consequences for small mammals. It is possible that the dominants in vegetation cover create a favorable microclimate for small mammals. The PCA analysis shows the presence of two significant factors for the distribution of microtine rodents. The first factor is associated with the balance of humidity and illumination, the second with nitrogen availability in combination with low illumination. The ecological divergence of niches in two species of mice (pygmy wood mouse and yellow-necked mouse) was observed. In relation to the projective cover, the bank vole occurs both at very high (90%) and low (30%) values, which confirms the ecological plasticity of that species. For yellow-necked and pygmy wood mice, the optimal values of projective cover in studied communities range from 70 to 90%. However, yellow-necked mice can also live in plant communities with a plant cover index about 4050%.
Zooplankton in the temporary recreational pond in microdistrict 13 of Samara
Authors: Gerasimov Yuri Leonidovich
Published: November 2022

Rotifers make a significant contribution to the self-purification of the water bodies. Full self-purification is especially important for water bodies of recreational zones of settlements. These water bodies are constantly visited by local residents and conditions in these water bodies must comply with sanitary standards and they shouldnt be dangerous to human health. At the same time, the rest of residents on the banks of urban ponds leads to a deterioration in their ecological and sanitary conditions. Therefore, it is necessary to monitor the ecosystems of urban ponds located in recreational areas and among resident buildings. The Rotifera and Crustacea community in the small temporary urban recreational pond in microdistrict 13 of Samara was studied in 2012 and 2018. The pond is situated in the middle of the plot among Kirov avenue, Georgy Dimitrov street, Stara-Zagora street, Moskovskoe highway. 23 Rotifera (13 familia) and 24 Crustacea species (8 familia) have been identified. All species are common for water bodies in the Samara Region. Most of the species live in other ponds of Samara. Brachionidae dominated in the Rotifera community, Cyclopoidae и Daphniidae dominated in the Crustacea. The seasonal dynamics of the population size from May till November was studied. The Rotifers largest abundance in both years was observed in spring and autumn. The crustaceans largest abundance was in 2012 in October, in 2018 in July. The indicator species of Rotifera and Crustacea correspond to the -mesosaprobic zone. While resting people trample grass on the banks, the soil washout causes eutrophication and shallowing of the pond. It is necessary to remove bottom sediments and strengthen the pond banks to improve the state of the pond.
The effect of ultraviolet radiation on the reproductive function of male white rats
Authors: Dudenkova Natalya Anatolievna , Shubina Olga Sergeevna
Published: November 2022

Ultraviolet radiation is an area of electromagnetic radiation that is not perceived by the eye, which occupies the middle range between visible and X-ray radiation. Scientists and doctors have proven that ultraviolet radiation in moderate doses has a rather positive effect on the human and animal body, as well as on their health. The effect of ultraviolet radiation on the skin, blood and immune system has been well studied. However, there is practically no information about the effect of ultraviolet radiation on the reproductive system, and in particular on the male, which is most susceptible to the thermal effect received from it. Our experiment indicates that exposure to ultraviolet radiation adversely affects the reproductive function of the male gonads (testes). So, with short-term exposure to long-wave ultraviolet radiation, the protective resources of the body are first activated and active replenishment of the spent resources of the body begins, which affects a slight increase in the total concentration of epididymal spermatozoa, and their viability indicators increase slightly. With a longer exposure to long-wave ultraviolet radiation, in particular due to the thermal effect caused by it, there is a decrease in the total concentration of epididymal spermatozoa, as well as a decrease in their viability.
Features of the balance of ecosystem services and risks for woody plants in the Samara Region
Authors: Zaika Anna Sergeevna , Kavelenova Lyudmila Mikhailovna
Published: November 2022

The development of the concept of ecosystem services, started at the end of the 20th century mainly by foreign authors, has recently extended to the consideration of various aspects of the mankind interaction with the surrounding natural complexes, including the functioning of agroecosystems of various types and urban environments. The urban ecosystem includes various forms of infrastructure that provide services to the population, including green infrastructure consisting of natural plant systems and associated green technologies. Green infrastructure ensures the implementation of regulatory, supportive and cultural ecosystem services. On the other hand, the reverse interaction has recently been considered the practice of considering ecosystem services provided directly by the urban environment for the conservation of biological diversity has appeared. The provision of ecosystem services is an important role of urban plantings, and the contribution of woody plants to their implementation is particularly important. Despite the small share of the area occupied in the urban environment, the use of land covered with trees contributes to a significant reduction in the ecological footprint of the city. However, the quality of ecosystem services provided is largely determined by the vital condition of a particular instance of trees and depends on their specific features. Based on the actual data obtained during the survey of model plots of street plantings in Samara, the authors consider the features of the balance between ecosystem services and risks associated with the species composition and vital state of the tree component of plantings in the urban environment. For a number of species of woody plants, their actual role in the urban environment has been factorially analyzed, taking into account the effectiveness of the implementation of ecosystem services and the severity of problems associated with their condition or life characteristics.

The paper presents the results of studying the population structure of rare species Hedysarum argyrophyllum Ledeb., H. cretaceum Fisch., H. gmelinii Ledeb., H. grandiflorum Pall. and H. razoumowianum Fisch. et Helm in the Volga and Ural regions. The study area covers Volgograd, Samara, Saratov, the southern part of the Ulyanovsk and the western part of the Orenburg Regions and the Republic of Bashkortostan. 10 coenopopulations of Hedysarum argyrophyllum, 18 coenopopulations of H. cretaceum, 410 coenopopulations of H. gmelinii, 1800 coenopopulations of H. grandiflorum, 1400 coenopopulations of H. razoumowianum were examined. The work was carried out in 20002021 using population-ontogenetic methods. The studied representatives are rare, their population characteristics are subject to changes under the influence of anthropogenic factors. Species have sufficient potential for self-recovery of natural populations. The ontogenetic spectra of populations are similar in their parameters; the dominant fraction of individuals is the generative one. Common features are the fluctuation type of population dynamics and ontogenetic structure of model representatives, relatively low demographic characteristics, weak ability for self-maintenance and self-recovery of populations under anthropogenic load. Anthropogenic load leads to a decrease in the number of individuals, their density and the gradual aging of populations.

The aim of the work is to reveal the existence of a connection between the leading paw used and individual characteristics of dogs, such as sex, age, and percentage of jackal blood. The identification of such patterns can help to adjust or select a more effective method of training a working dog, which is the relevance of this work. Using the first-pitch method, it was found that of the 76 jackal-dog hybrid, 46 favored the right paw, 23 favored the left paw, and 7 used both paws equally. Among right-handed ones there are 31 females and 15 males, among left-handed ones there are 3 females and 20 males, and among ambidextrous ones, those who have not decided with the leading limb, there are 2 females and 5 males. In general, there is a correlation between the sex of the dog and severity of motor lateralization: females prefer the right limb more often than males, and males, in their turn, prefer the left limb more often than females. Among older dogs there are only jackal-dog hybrid with pronounced lateralization, i.e. only left- or right-handed dogs. As for the percentage of jackal blood and emotional functionality no regularities were found.

The paper deals with a comparative analysis of the features of the population organization of the Myodes glareolus and the Apodemus uralensis on the territory of the State Nature Reserve Kologrivsky Forest named after M.G. Sinitsyn. This research is a part of a long-term monitoring of the state of populations of dominant species of small mammals on the site of the Kologrivsky Reserve. The paper presents factors of the dynamics of the density of rodent populations, considers trends in the number of individuals of the studied species, their sex and age structure, characteristics of interior and exterior features. The general tendencies and regularities of rodent adaptation to various external environmental factors are revealed. The authors have established a direct statistical dependence of the density of the studied populations on the average air temperature and an inverse dependence on the amount of precipitation. The dependence of exterior and interior features on the gender and age structure, population dynamics and weather conditions is traced. The role of autoregulation of integral population indicators as one of the mechanisms for maintaining its homeostatic state is considered. The revealed patterns allow us to make a forecast of the population dynamics of the Myodes glareolus and the Apodemus uralensis on the territory under consideration. It is possible to use the results of the study as a control example for comparison with other populations of cyclomorphic rodents in ecologically contrasting conditions of forest biocoenoses.

This paper describes some results of the research of mammals and birds fauna and population structure as ecosystem condition indicators, and provides an investigation of flora and soil to establish habitats structural peculiarities. The research covered an area of a future road from Kharp Village through a ski resort to the Snowflake International Arctic Station (Priuralsky District, Yamal-Nenets Autonomous Okrug, Russia). Our study aims at assessing the environmental impact of the project. In the areas typical habitats, we registered two small mammal species (Clethrionomys (= Myodes) rutilus, Sorex araneus), 25 bird species, traces of three medium and large mammal species presence (Lepus timidus, Vulpes vulpes, Rangifer tarandus). Micromammals show very low abundance, low indices of small mammal communities diversity and sustainability, Cl. rutilus being an absolute dominant. The bird species show a relatively low level of abundance. The composition and structure of animal and bird communities are in line with natural and climate conditions of the Polar Urals foothills. The investigation results revealed low resource capacity, sustainability and biotic communities vulnerability to any impact. The study materials suggest that the future road from Kharp Village to the Snowflake International Arctic Station will not significantly harm mammal and bird population of the area, and will provide facilities for recreational and tourist activities, and will mitigate risks of anthopogenic impact on these vulnerable ecosystems.

This paper deals with the field integrated geo-environmental research of lake Dus-Khol in the summer of 2021. Under the leadership of the Tuvan Scientific Center in the context of project to identify maximum permissible and optimal recreation load on the specially protected natural area the study collected and updated data on the number of visitors and the condition of the coastal ecosystem health. Lake Dus-Khol is located in Tandinsky kozhuun of the Republic of Tuva, 3 km away from lake Hadyn. Dus-Khol is one of the most visited lakes in the Republic of Tuva. The main attractions are therapeutic mud, high-quality rapa, heliotherms, and drinking mineral waters. A regime of regional specially protected natural area has been introduced on the territory of the lake, the main goal is to preserve natural wetland complexes in their natural state and protect them from the negative effects of anthropogenic and man-made factors. Based on the data obtained, the types of recreation, the values of recreational load and the degree of recreational digression of the ecosystem are determined. The forms of recreation, recreation load values and recreation degree of ecosystem were identified based on the received data. The ways of optimizing recreational nature management on the lake were proposed. The visitors were counted by route counting method during the peak season. Data on the types and scale of recreational activities, as well as the degree of recreational digression of natural complexes of the coast were carried out by visual assessments and surveys.

The halophytic vegetation of the Lopatinsky District in the Penza Region was studied on the example of five solonets (Litvinovsky, Lipovsky, Staro-Vershautsky, Olginsky and Belogorsky). Halophytic meadows (44,0%) slightly prevail over halophytic steppes (36,0%) on all of these salt lakes. 550 species of vascular plants have been identified in the Lopatinsky District of the Penza Region, 29 rare species have been identified, 2 species (Iris aphylla, Stipa pennata) are protected at the federal level and 29 species (Adenophora liliifolia, Adonanthe vernalis, Allium lineare, Allium podolicum, Allium praescissum, Amygdalus nana, Artemisia santonica, Astragalus varius, Bupleurum falcatum, Dianthus volgicus, Galatella linosyris, Galatella rossica, Galatella villosa, Gelasia ensifolia, Hippochaete ramosissima, Iris aphylla, Jacobaea erucifolia, Plantago maxima, Plantago salsa, Potentilla alba, Pulsatilla patens, Rosa corymbifera, Salvia nutans, Silaum silaus, Spiraea crenata, Stipa borysthenica, Stipa pennata, Stipa tirsa, Syrenia montana) are protected regionally. In all of these five solonets, perennial grasslands predominate among halophytic meadows (36,0%), and semi-shrubby grasslands predominate among halophytic steppes (23,0%). The main stages of halophyte vegetation demutation in various ecological conditions have been established. Halophytic meadows are formed in saline and moist soils: annuals, perennials, turf and slag. On the contrary, in the conditions of saline and dry soils, halophytic steppes are formed: annual grasslands, perennial grasslands, semi-shrubby. Of the studied salt shakers of the Penza Region the salt shakers of the Lopatinsky District are the closest to the salt shakers of the Maloserdobinsky District in their structure and dynamics.
