The Lower Volga region is important for studying natural and climatic crises as a factor of cultural and economic changes since the local Neolithic and Eneolithic societies are marked by the early appearance of ceramics, cattle breeding and copper items. However, the impact of natural and climatic crises on these processes has not been considered earlier for a number of reasons. First, most of the sites had not detailed information obtained by the analytic research on past environmental and climatic situation. Second, numerous and contradictory radiocarbon dates prevented from determination of the chronological frameworks of these processes. During the period of 2007–2020 the situation has begun to change with the appearance of new archaeological information including homogenous and stratified archaeological sites. The multidisciplinary research made it possible to obtain new data on the chronological framework of the Neolithic–Eneolithic cultures of the Lower Volga region in context of paleoclimatic reconstructions. The results of archaeozoological studies and technical-technological analysis of ceramics had a significant meaning too. Determination of the species composition helped to establish differences in zoological collections of the Neolithic of the Northern Caspian and the steppe Volga region. It was demonstrated that the emergence of a food producing economy in this territory is associated not with the Khvalynsk, but with the earlier Caspian culture. The entire set of data made it possible to bring the development of the question of environmental factors in cultural and economic changes in the Neolithic–Eneolithic of the Lower Volga region to a new level.
THE WRITINGS OF URAL ORIGIN ON NAPOLEON THE ANTICHRIST OF THE FIRST HALF OF THE 19TH CENTURY
Authors:   Ural Federal University, Pochinskaia Irina V.
Published: September 2021

The article is devoted to the analysis of two Old Believers eschatological writings created in the Urals in 1820–1840s, which are now kept in the largest collections of the Ural Cyrillic old printed books and manuscripts: the Laboratory of Archaeographical Studies (LAS) of the Ural Federal University and the library of the Ekaterinburg Orthodox seminary. One of these essays is “Tolkivanie o Antichriste” (“The exegesis on the Antichrist”), which substantiates the idea that Napoleon I is the Antichrist. It has already been introduced into scientific circulation in the 19th century, but its copies from the LAS fund allowed revealing a new data about the history of its existence. The article clarifies the date of the essay, determines its impact on later Old Believers literature. The second essay, “Tsvetnik” (“Flower Garden”), continues the theme of the first one, relying on it. “Tsvetnik” is a rather complicated and multifaceted work, containing a lot of reasoning. It covers a lot of questions, problems and assessments of domestic and foreign events contemporary to the author. The main task of the essay was to substantiate the fact that Louis Napoleon, the future French emperor Napoleon III, was the new hypostasis of Napoleon I, the antichrist. The article analyses in detail main ideas of the Tsvetnik’s author, the source base of his work, which included not only traditional Christian literature, but also contemporary to the author secular publications.
BECOMING A SOVIET CITIZEN: LANGUAGE CHOICES IN N. F. TERENTYEV’S DIARY
Authors:   Perm State University, Bugrimova Tatiana V.
Published: September 2021

The article based on the diary of the young writer N. F. Terentyev from Komi ASSR who wrote his records in the Komi language from 1936 to 1939 considers peculiarities of the “subjectivity” formation in the non-Russian language discursive space. The author hypothesizes that non-Russian people in the 1930s USSR acquiring new subjectivity, began not only to speak Bolshevik but also appropriated a more prestigious discourse in which the Russian language was endowed with revolutionary consolidating potential. The material of the diary reveals two levels of the formation of a Soviet citizen. As regards Terentyev, the first level is related to the local context: the diarist advocates the development of the countryside, collects folklore, adheres to the national literary tradition in terms of the description of the countryside life. The second level is connected with Terentyev’s desire to be involved in more significant events: he joins Komsomol, uses Marxist language in representation of the everyday life, actively participates in the translation of the texts written in the Russian language. The process of writing the diary reveals not only Terentyev’s aspiration to become a Komi writer but also his active civic engagement. Terentyev’s ambition was to become a Komi writer, a representative of the emergent national intelligentsia. Internalizing “cultural revolution discourse”, Terentyev defined Komi literature as backward which should be developed in order to keep up with the Russian literature. In this context, his personal development as a writer involved overcoming of not only personal backwardness (which he acknowledged) but also backwardness of his native culture.
THE DEMIDOVS ON THE WAY TO AN INDUSTRIAL DYNASTY: STRATEGIES FOR ENSURING THE CONTINUITY OF THE FAMILY BUSINESS
Authors:   S. I. Vavilov Institute for the History of Science and Technology of the RAS, Yurkin Igor N.
Published: September 2021

On the example of representatives of the first two generations of the Demidov family, the paper shows how one of the most successful entrepreneurial dynasties of the first half of the 18th century ensured the succession of development of the family business. The strategies of its transmission by inheritance are traced in detail. The legacy of Nikita Demidov, the dynasty’s founder, was divided according to the “Law on single inheritance” (1714): the transfer of property was conflict free, but gave rise to hidden grievances that influenced the further relations of the heirs. The division of the inheritance of the middle son, Grigory Demidov, who was murdered in 1728 and did not determine his heir, also gave rise to a long-term enmity among family members. Akinfiy Demidov’s choice of a successor with careful preparation for the transfer of the undivided industrial economy to him also turned out to be unsuccessful, since most of the heirs were not satisfied. It was only the youngest son, Nikita Nikitich, who managed to carry out the operation of transferring property rights in such a way that this transfer could be considered “equalizing”, “amicable” and therefore “sinless”. The author claims that the circumstances and forms of ownership transfer by each member of the clan influenced the strategies chosen by the other members. With this in mind, the implementation by N. N. Demidov of the option, which ensured the conflict-free transfer of the family business, is regarded as a result of taking into account the mistakes and failures of his predecessors. The influence of external factors on these processes, in particular, changes in legislation regulating the field of family law, and transformations associated with a change in the estate status of actors, is also noted.
MERCHANTS AND NOBLES LUGININS: THREE GENERATIONS OF THE ZLATOUST FACTORIES OWNERS OF THE SECOND HALF OF THE 18TH CENTURY
Authors:   Ural Federal University, Bochkareva Elena S.
Published: September 2021

The article presents the history of the ownership of Zlatoust mining plants by three generations of the Luginin family. It shows direct dependence of the dynamics of ownership and inheritance of plants on the vicissitudes of the family history. It is established that the founder of the Zlatoust factory farm, L. I. Luginin, relied in his business activities on the help of his son Maxim, who took over the management and control of a new part of the family business — the Ural factories in 1769. M. L. Luginin died in the middle of 1770s and L. I. Luginin was left without an assistant and a trained heir. The grandchildren of the factory owner, due to the life circumstances associated with their new noble status, character traits and age, failed to adopt the grandfather’s experience and did not become an equivalent replacement for their father. After the death of the founder, during the period of guardianship management of the factories, the middle grandson, Larion Maksimovich, showed interest in the factories, but he also died before he had been in the factories for two years. The transfer of ownership of the district to the most unworthy of the heirs, I. M. Luginin, eventually led to the exit of the estate from the possession of the family. Zlatoust factories, located far from the rest of the family’s possessions, required constant control of the owner, his participation in the management. In this case, the succession should have been manifested in the active participation of the heirs in the management of the district, personal control over the execution of orders. It is concluded that the succession of generations of the family is of great importance in the early stages of the organization of the business, when the personal control of the owner is a significant factor in the preservation of the business in the hands of the family.

Published: September 2021

Discussions approximately an environmental control method for deep seabed mining in the Area had been underway for some the years. Both states and scientists have known for such an environmental control method. In 2018, the International Seabed Authority has followed its first 5-year strategic plan, masking all elements of its mandate. This article examines the brand-new strategic plan integrates factors of an environmental control method and what is probably missing. It demonstrates that even as a few overlaps exist, there are numerous key gaps left via way of means of the modern strategic plan which will be stuffed via the way of means of an environmental control method.
To operationalize those desires and objectives, development ought to be measurable; thus, objectives are set, reviews are assessed, and suitable responses are awarded. Many control equipment and toots are relevant for accomplishing environmental desires. To date, the ISA has taken into consideration marine spatial making plans in large part across the modern exploration settlement blocks. Other factors of environmental control, which include the necessities for baseline studies, effect assessment, post-effect tracking, and the remedy of dangerous consequences and extreme damage want to be carried out to assist well-described environmental desires and objectives. We advocate that this making plans be done for scales largethan man or woman blocks, through a Strategic Environmental Management Plan, to make certain sustainable use of ocean assets throughout the Area.

Published: September 2021

In this document, we will talk through information collected on all trends in mining in the underground environment as much as what happens in the world as or new machinery America provides the highest mining production in underground mining. We often discover opportunities for improvement in both productivity and costs. Of all these methods, braking is not only the most common, but also offers the largest share of overall production, nearly 50 percent.
These underground mining methods are often determined by the deposits and the economics of mining and are therefore somewhat beyond the control of the operator(Trends in underground mining for gold and base metals | McKinsey, s. f.)

Published: September 2021

Many Deaf Filipinos remain unemployed despite the increased attention level from the hospitality industry. The study aimed to examine the levels of awareness on Deaf culture and FSL skills within the hospitality industry of Zamboanga City to foster sustainable employment - including quality service; it used a descriptive research design employing qualitative and quantitative approaches.  The sample group was purposively selected from 4 hotels and 8 restaurants - duly accredited by the Department of Tourism Region 9 as of December 31, 2018. The study revealed that Zamboanga City hospitality industry stakeholders were aware 1) of Deaf culture; that 2) Deaf individuals can visually communicate through reading, writing, gestures, or FSL; 3) they can visually communicate with Deaf individuals regardless of their FSL knowledge or skills; also, 4) there was no significant difference in the respondents’ levels of awareness on Deaf culture and FSL skills in the area; 5) an intervention program is needed to increase Deaf Zamboangeños' hospitality employability. The study concluded that Zamboangeño hospitality industry stakeholders 1) were aware of Deaf culture and FSL skills despite linguistic differences; 2) can visually communicate with Deaf individuals despite having little to no FSL skills nor Deaf culture knowledge; also, 3) the communication models affect Deaf individuals' hospitality employability and capability; and, 4) Deaf culture awareness and FSL skills through interactive interaction among Deaf and hearing individuals, within hospitality business operations, are crucial in emerging communication patterns.

BACKGROUNDWithin a decade, the expeditious evolution of technology has catalyzed digital advancements employed even at one’s fingertips. Now a household item, smartphones host innumerable apps supporting users across the world. One of the rising market niches includes mental-health based applications, which further branch into topics of lifestyle, habit-building, and productivity.METHODSThis systematic review explores quantitative and qualitative studies discussing variables of influence on social behaviours and trends for mental-health based applications. Searched databases include Science Direct, ProQuest, and Scopus with further supplementation of grey literature from Science Daily, Common Sense Media, and Extreme Networks. Extracted data precluded meta-analysis given the significant heterogeneity in study design, outcomes, and measurements. Studies were screened with a piloted tool and screening & extraction was completed independently among two authors. Disagreements following reconciliation between the two authors were settled by a third author. RESULTSAppraised articles identified trends & behaviors associated with app functionality, accessibility, and data/privacy security. The decline or absence of these features correlated with low user engagement.CONCLUSIONPrevalent features were determined for enhanced functionality, accessibility, and database security, which may serve to bolster apps within mental-health and its niches.
Fake News Known as Fake Still Changes Beliefs and Leads to Partisan Polarization
Authors: Bai Hui
Published: September 2021

Helping citizens recognize fake news as fake has been a popular approach for curtailing the effect of misinformation. However, this paper points to its limitation by revealing that misinformation that we already know is false can still change our beliefs and attitudes. In five experiments, participants who were thoroughly instructed that they were going to read a made-up article still ended up believing the content and changed their political preferences or behavioral intentions. The effects are resistant to corrective efforts and persistent across time. People exposed to misinformation they knew to be false still believe the content despite being instructed to be deliberative and to try to not be affected or provided with the real information. The effects were observable two days later and again nine days later after the initial exposure. These findings have profound implications for misinformation research, media practices, polarization and democracy, and common research practices, such as deception and debriefing after deception.
The New, COVID-Driven Outdoor Recreationists in the U.S.: Who They Are, Who They Aren’t, and Who Will Stay Involved
Authors: Rice William L. , Taff B. Derrick , Lawhon Ben , Newman Peter
Published: September 2021

As the COVID-19 pandemic spread across the United States, many residents began participating in outdoor recreation for the first time, or returned to outdoor recreation after a prolonged hiatus. During the first year of the pandemic, many parks in the U.S. experienced record visitation as overall park and protected area visitation increased across much of the country. Part of this increase in visitation was likely the result of existing outdoor recreationists who increased their participation during the first year of the pandemic because of restrictions to other types of leisure activities. However, it is possible that much of the increase in outdoor recreation and park use was the result of a recreation substitution, as new outdoor recreationists either tried outdoor recreation for the first time or returned to outdoor recreation because they could not do their more preferred means of recreational activities (e.g., go to bars, movies, gyms, etc.). Research concerning these new participants is sparse at present (Grima et al., 2020; Outdoor Industry Association & Naxion Research Consulting, 2021). Therefore, the research detailed in this report focuses on the results of a national panel study aimed at gaining a more robust understanding of both 1) how these new outdoor recreationists differ from other participants and non-participants and 2) the behaviors of these new outdoor recreationists. In doing so, we provide insights concerning information used by new participants to aid their transition to outdoor recreation, how helpful this information was, what activities they participated in, where they participated in these activities, and if they plan to continue participating once the pandemic is over.
REPRODUCTIVE BURDEN AND ITS IMPACT ON FEMALE LABOUR MARKET OUTCOMES IN INDIA: EVIDENCE FROM LONGITUDINAL ANALYSES
Authors: Tiwari Chhavi , Goli Srinivas , Rammohan Anu
Published: September 2021

We use nationally representative data from two waves of the Indian Human Development Surveyto provide causal evidence on the role of inter-temporal changes in fertility behaviour ininfluencing female labor market outcomes. Our multivariate regression estimates show that anincrease in the number of children reduces labor force participation and earnings. We furtherinvestigated the impact of fertility changes on transitions from the labor market. The results showthat women who had more than three children in both rounds of the survey had a 3.5 percentagepoints higher probability of exiting from the labor market. Disaggregated analyses by caste,economic status and region show regional heterogeneity, and the probability of dropping-out ofthe labor market due to fertility changes is greater for non-poor women and those from sociallydisadvantaged castes.
The possibility of a decentralized economy in China and the USA
Authors: Tong Antonia
Published: September 2021

The 21st century sees a sharp increase in political, military, and economic competition. Acountry's competitive position in the world is measured by the strength of its economy. Since 2009bitcoin was created, the decentralized economy became the trending research topic on google in2021. Many developing countries try their best to find a way to decentralize their high-costoperations and optimize possible resources. Decentralization, as opposed to centralization, is theprocedure through which a firm's operations, especially those concerning planning and management,are spread or outsourced away from the centralized, dominant place, group, and bureaucracy. It isdefinitive as a component of the decentralized economy since it is a set of commodities that enablethe community to have sovereignty over an individual’s wealth without requiring third parties, suchas a bank. Regional essential services are chosen by publicly elected officials in a decentralizedeconomy system, whereas policy decisions are decided by a parliament comprised of electedmembers from each region in a centralized economic system. Two types of parliamentary conductare explored. This thesis offers a foundation for choice, comparative, and a category of schemes formanagerial decision is established, and decentralized (in the classic sense), centralized, and unconstrained economic subclasses are studied in both the United States and China. It also identified and discussed the channels through which a decentralized economic system can contribute to theeconomic growth. In a basic illustrative structure, parameters for rating the schemes are developed and used. It is discovered that a universal predilection for one of the subcategories cannot be justified without significantly reducing the model's possibilities in the United States and China.

Published: September 2021

Introduction: Junk food consumption among adolescents has become a serious issue that may lead to harmful effects on health. Dietary patterns of people are shifting from homemade foods to junk foods. Therefore, this study was undertaken to assess the awareness and practice of junk foods among adolescents.

Methods: A descriptive cross-sectional study was conducted among adolescents of secondary level students. A simple random sampling technique was used to select the sample and the sample size was 237. Data collection was done from April 15, 2019 to May 14, 2019. A set of semi-structured self-administered questionnaire was used for data collection. Descriptive and inferential statistics were used to analyse and interpret the findings.

Results: The findings showed that more than three-fifth (67.9%) of adolescents had a moderate level of awareness about junk foods. Half (49.4%) of them consumed junk foods highly. All (100%) adolescents have consumed junk foods regularly whereas two-fifth (42.2%) replaced meals once a week with junk foods. Four-fifth (82.3%) of adolescents did not bring tiffin from home. There was no significant association between the awareness and practice of junk foods (p < 0.05).

Conclusions: This study concludes that most of the adolescents possessed a moderate level of awareness of junk foods. Majority of them did not bring tiffin from their home. Around half of them consumed junk foods in their daily life. Majority of them were aware of junk foods, although they still consumed junk foods.

Metaheuristic optimisation algorithms have been increasingly used because of their superior ability to find globally optimal solutions. Theoretically, these algorithms are very powerful and can be applied in all types of optimisation problems. However, in reality, their performance depends on the characteristics of each optimisation problem class. In addition, the complexity of an algorithm is an important factor affecting its application in specific design problems. In this paper, the Rao optimisation algorithm, one of the newest metaheuristic algorithms, is presented for the optimisation algorithm of steel frame structures. The advantage of the Rao algorithm is that it is quite simple with few parameters, so engineers can easily apply it in daily design tasks. A nonlinear inelastic analysis is used to consider the nonlinear behaviors of the steel structure. A two-story space steel frame is studied. The results show that Rao-1 is more stable and converged more quickly but easily trapped in local solutions than Rao-2 and Rao-4. Rao-4 is more efficient in global search but its stability is less than other algorithms. Keywords:nonlinear inelastic analysis, optimisation, Rao algorithm, steel frame.

Covid-19 disease is still ongoing. It is necessary to do intensive research related to age, sex and congenital diseases so that management can be better planned. The research was conducted using data from Indonesian Navy personnel and their families, retired Indonesian Navy and their families. This study used k-means clustering for data grouping of Indonesian Navy personnel based on age, sex and congenital disease characteristics. The results of the k-means cluster clustering show that the k = 2 cluster has not been able to provide an explanation of the relationship between age, sex and comorbidity with the risk of death due to Covid-19. However, in the cluster with k = 3, it turns out that deaths due to Covid-19 are related to old age, men, even though there is no congenital disease. Meanwhile, using the k = 4 cluster, it is increasingly clear that deaths due to Covid-19 are closely related to old age, both men and women, with comorbidities.

Published: September 2021

Currently the need for domestic packaging paper continues to increase, driven by the level of consumer awareness about sustainable packaging. PT XYZ is a local company engaged in the Corrugated Cardboard Box (KKG) industry. So far, the problems in fulfilling incoming orders every month are not optimal with an average of about 30% inaccuracy. This is because the orders that enter cannot be predicted. As an effort to win market competition in packaging paper, PT. XYZ must improve the fulfillment of incoming orders by predicting incoming orders using the Long Short-Term Memory (LSTM) method. The aim of this research is to provide a predictive model for incoming orders in accordance with the needs of order fulfillment to be applied to production planning. So that order fulfillment can be on time. The method used in predicting incoming orders is the Long Short-Term Memory (LSTM) method using weighting evaluations with the lowest Root Mean Squared Error (RMSE) and Augmented Dickey-Fuller test (ADF).

Electrical energy is an important foundation in world economic growth, therefore it requires an accurate prediction in predicting energy consumption in the future. The methods that are often used in previous research are the Time Series and Machine Learning methods, but recently there has been a new method that can predict energy consumption using the Deep Learning Method which can process data quickly for training and testing. In this research, the researcher proposes a model and algorithm which contained in Deep Learning, that is Multivariate Time Series Model with LSTM Algorithm and using Teacher Forcing Technique for predicting electrical energy consumption in the future. Because Multivariate Time Series Model and LSTM Algorithm can receive input with various conditions or seasons of electrical energy consumption. Teacher Forcing Technique is able lighten up the computation so that it can training and testing data quickly. The method used in this study is to compare Teacher Forcing LSTM with Non-Teacher Forcing LSTM in Multivariate Time Series model using several activation functions that produce significant differences. TF value of RMSE 0.006, MAE 0.070 and Non-TF has RMSE and MAE values of 0.117 and 0.246. The value of the two models is obtained from Sigmoid Activation and the worst value of the two models is in the Softmax activation function, with TF values is RMSE 0.423, MAE 0.485 and Non-TF RMSE 0.520, MAE 0.519.

Topicality. Industry, as one of the components of the national economy of any country, plays one of the leading roles in it due to the fact that it is industry that creates a large part of the GDP. In addition, the leading role of industry lies in the fact that the degree of satisfaction of society's needs for high-quality products, ensuring the technical re-equipment of production and its intensification depends on its success. Formed difficult financial and economic conditions in the country's economy have not yet made it possible to achieve significant changes in the direction of stabilizing industrial production, improving the sectoral structure and its social orientation. For the production of various forms of ownership, functioning in market conditions, it is essential, on the one hand, to develop principles and norms of strategic management, and on the other, to their practical use in order to increase the efficiency of industrial production. It is the isolation of these problems that made it possible to determine the direction of research on the methodology for the formation of indicators of the effectiveness of management decisions at industrial enterprises.
Aim and tasks. The aim of the work is to develop and substantiate a methodology for indicators of the effectiveness of management decisions at industrial enterprises. Achievement of the set research goal led to the formation and resolution of the following tasks: to study the system of main indicators of the enterprise's performance; to form a methodological basis for management decisions.
Research results. The work developed and substantiated a system of main indicators of the enterprise's performance, which provides for the calculation of the following profitability indicators: production, sales, assets, equity, production assets, personnel, invested capital, etc. It has been established that efficiency is the sum of two factors: the difference between results and costs, which indicates a positive balance (i.e., the benefits that are brought by human efforts), and the ability of this difference to meet the real vital needs of society (people). It is shown that the sources of strategic ideas in centralized decision-making are a high level of management (top management) due to the fact that it is there that information is concentrated, as well as central services and heads of production departments.
Conclusion. The obtained results of the study make it possible to systematize the information obtained by calculating the indicators of the efficiency of enterprises and to formalize the process of making managerial decisions; to improve the scientific support of the process of implementation of strategic changes at the enterprise by using the four-stage model of "gradual (evolutionary) growth of changes".

The urinary tract of dogs is usually considered to be a sterile environment, with the exception of the distal urethra, which is composed of resident microorganisms from the vagina or foreskin. Approximately 14% of dogs can develop urinary tract infection (UTI) during their lifetime, being more common in females and the elderly. The indiscriminate use of antimicrobials in the treatment and prevention of diseases of the urinary tract can contribute to the development of bacterial resistance. The aim of this study was to identify the microbiota involved in disorders of the urinary tract of dogs in the municipality of Formiga, Minas Gerais and to establish the susceptibility profile of these agents against antimicrobials commonly used in the veterinary clinical routine. The samples used were granted by a veterinary clinical analysis laboratory in the municipality of Formiga - MG, with 13 biological samples being made available and submitted to culture and antibiogram. In eight (61.5%) of the 13 samples, it was possible to notice the presence of Staphylococcus spp., followed by E. coli (15.4%), Enterococcus sp. (7.7%), Streptococcus sp. (7.7%) and Proteus sp. (7.7%). Regarding the susceptibility profile to antimicrobials, it was possible to conclude that for amoxicillin + clavulanic acid, with approximately 61.5% of the samples, it was the antimicrobial with the best efficiency.

Necrotizing fasciitis is a sudden-onset soft tissue infection that progresses rapidly to systemic inflammatory response syndrome (SIRS), sepsis and death. Treatment is surgical. The present literature review aims to report a case of type I necrotizing fasciitis in a feline who suffered extensive trauma from biting, and to expose the main concepts about Necrotizing fasciitis rarely addressed in Veterinary Medicine. The following case progressed to severe inflammatory anemia, impairment of the muscles and the right kidney. Predisposing factors in felines include, immunosuppression, cats that are positive for FIV, FELV and the use of corticosteroids for long periods. Immediate surgical therapy is the treatment recommended in necrotizing fasciitis. The main pathological agents in cats is Streptococcus canis and Estreptococcus sp from group G, Enterococcus and Escherichia sp and Pseudomonas sp, confirmed in the culture. Rapid surgical treatment and adequate antibiotic therapy are essential for successful treatment.
Avaliação da ocorrência de alterações odontológicas em bovinos mestiços em idade de abate

Brazilian cattle raising stands out as the largest exporter of beef in the world due to the large number of herds raised on pasture, the most economical and practical way of offering food to animals. However, there are many pastures with low nutritional value. Solid foods pass through an interdependent process during the digestion, starting at chewing where they are broken by the teeth to facilitate the process. If there is any dental deficiency, the animal may have problems with digestibility and subsequently cause a burden on the organism. Due to the absence of studies that emphasize the quality of the teeth of these animals, it is necessary to evaluate the dental alterations of the cattle to intercept the incurable diseases that reduce the production, in addition to the possibility of animals’ death. 72 bovine mandibles were used to assess dental alterations. After this process, the specimens were subjected to maceration and clarification with sodium hypochlorite for the preparation of anatomical pieces. In addition, a questionnaire on the oral health of cattle was also prepared and applied to understand the main oral pathologies of cattle in the North and Northwest Fluminense regions. As the experiment used mandibles acquired after slaughter, it was possible to identify the possible mandibular anomalies that affect the cattle. The main alterations found were: increased diastema (20%), fractures (18%); irregular wear (15%) and tooth absence (11%). Of the 27 interviewed owners, 15 reported oral problems in the cattle, 11 of which confirmed tooth loss. In addition, all owners assumed that the animals' oral health was never assessed by a veterinarian. Through this methodology, it was possible to emphasize the need for analysis and dissemination of research related to bovine dentistry in order to avoid damage to the general health of these animals, which may result in decreased production.
Uso de animais na experimentação animal: Revisão

Published: September 2021

The present work aims to review the aspects related to animal experimentation, presenting historical, ethical and practical aspects intrinsic to the theme. Since ancient times, animals have been used in scientific research that tests the effectiveness, mechanisms of action and toxicology of chemical substances with potential for use as new treatments for diseases. The use of animals in experiments has aroused a strong discussion within the academic community and animal protection groups. Seeking to reduce the use of animals in scientific research, alternative methods are being used based on the principles of the "3Rs" for carrying out animal experimentation, that is, with a focus on replacement, reduction and refinement. Well-designed experiments, which use an adequate number of animals, combined with an adequate statistical analysis, guarantee the robustness and validity of the experimental results. It is worth mentioning that aspects related to the types of research and experimental models must be taken into consideration, always respecting the legal and ethical principles, which reflects in the validity and acceptability of the results.
