One of the steps in software development is to test the software product. With the development of technology, the testing process has improved to automated testing, which reduces the impact of the human factor on error and speeds up testing. The main software products for testing are considered to be web applications, web services, mobile applications and performance testing. According to the testing pyramid, when testing web services, you need to develop more test cases than when testing a web application. Because automation involves writing software code for testing, the use of ready-made tools will speed up the software development process. One of the most important test indicators is the coverage of search functionality. The search functionality of a web application or web service requires a large number of cases, as you need to provide many conditions for its operation through the free entry of any information on the web page. There is an approach to data-based testing, which involves working with a test data set through files such as CSV, XLS, JSON, XML and others. However, finding input for testing takes a lot of time when creating test cases and automated test scenarios. It is proposed to use artificial data set generators based on real values and popular queries on the website to form a test data set. In addition, it is possible to take into account the probable techniques of developing test cases. It is proposed to conditionally divide the software for testing into several layers: client, test, work with data, checks and reports. The Java programming language has a number of libraries for working at each of these levels. It is proposed to use Rest Assured as a Restful client, TestNG as a library for writing tests with checks, and Allure report for generating reports. It is noted that the proposed approach uses artificial intelligence for automated selection of test cases when creating a test to diversify test approaches and simulate human input and behavior to maximize the use of cases.

The paper presents a novel method of volumetric reconstruction of transient destructive processes using remote sensing by a group of unmanned aerial vehicles. The study is based on the most common class of such processes like forest fires, where a fire front is a determinant, and its propagation reflects the dynamics of the process. The effects of wind, smoke and fire, turbulence and vibration, interference, distortion, and obstacles lead to uncertainty of observations, to overcome which fuzzy sets, soft sets and gray numbers were combined. A spatial model based on a recursive eight-fold subdivision of space as well as on a hierarchical structure of virtual cells is proposed, which allowed to resolve the contradictions between the accuracy and rate of reconstruction. The set of possible states of virtual cells is determined and the algorithm of their classification based on the use of a five-channel image recognition system containing infrared, two main, and two additional optical channels is proposed. An algorithm for calculating a 3D observation vector, presented by an array of confidence vectors, is proposed, which can be used to determine the gray fuzzy state of virtual cells allowing a combination of observations from different observers and refining them sequentially. The terrain where the process evolves is represented by a soft gray fuzzy set of virtual cells, which belong to a specific state at the consideration time, allowing identification of convincing, uncertain, suspicious, and negative components. The first one defines a stable core of the fire front while the second one represents its variation caused by uncertainty. The proposed method allows the reconstruction of transient spatially distributed processes of other classes, smoothing the effects of distortions and noise and ensuring acceptable performance.

A mathematical model of a two-winding transformer for research of fast transient processes in windings in the form of an electromagnetic circuit, taking into account the main magnetic flux, own and mutual interturns and interwinding dissipation fluxes, transverse turns and longitudinal interwinding capacitances of the winding, is developed by using the straights method. The created model simplifies engineering calculations of fast transient processes in windings by applying the methods of the theory of electromagnetic circuits instead of the methods of mathematical physics, which are difficult for practical application. Transient processes and voltage distribution in transformer windings, under the action of pulse overvoltage in the form of a standardized pulse, are researched. References 8, figures 4.

Power supply systems with transformer-and-switches executive structures have a prominent place in the power supply systems of electrical and electro technological equipment. Voltage converters based on them with discrete-time control of semiconductor switches are characterized by high energy performance and the absence of distortions in the operating states of the output voltage and input current. The constant increase in the range and number of electricity consumers that require the use of such converters for their standardized operation, encourages their appropriate improvement, in particular to expand functionality. The peculiarities of forming a combined transformer- and-switches executive structure of a two-function converter for a rectified current power supply system, which is characterized by increased efficiency of semiconductor devices and lower losses in them, are investigated. Possible and expedient ranges of regulation of output voltage of such converters are defined. References 12, tables 2, figures 4.

A problem of electrical and radioelectronic equipment’s high energy pulse disturbance immunity is considered in the paper, in particular against microsecond high voltage disturbances (MHVD) in the power mains. It is showed causes of MHVD with amplitude up to 4 kV and even higher. A review of various protection methods against MHVD is carried out and it is shown that the use of a two-terminal network (TTN) with a significantly nonlinear current-voltage characteristic: varistors, suppressors and gas arrestors is the most effective. The report analyzes the operation principle of these two-poles and shows that the typical inclusion of such a device directly at the equipment’s input is not effective enough for cases where the high-frequency impedance of the mains is low. An L-circuit for connecting the TTN together with an LR link is proposed, and results of computer simulation with the aid of PSPICE showed that such a scheme reduces the MHVD amplitude on the network input of the equipment by 1.5 times comparing with the typical inclusion of such a device even under a low impedance of the mains Adding the low-pass filter to the L-circuit allows to reduce the MHVD amplitude by 40 and more times comparing with the typical inclusion of the TTN.

It is shown that in high-precision optoelectronic systems for measuring the linear displacements of objects with diffuse-reflecting surface, built on the basis of phase laser rangefinders, to ensure a given accuracy, it is necessary to compensate for the effect on the measurement of harmonic noise. Methods of compensation of this influence which are based on use of various algorithms of measurement of a phase shift proportional to distance which is defined are considered and analyzed. The disadvantages and advantages of each of the methods are evaluated, recommendations for their use are made. It is proposed to compensate for the harmonic interference of the use of electro-optical switches. References 12, figures 3.

Vinte anos depois, a Wikipédia continua a ser um caso notável de resistência na comunicação e informação, desde os assuntos de ciência ou política aos assuntos mais contingentes, muitas vezes com índices de desinformação menores do que grandes média informativos graças à constante atualização e vigilância comunitária. Porém, pouco se sabe sobre os voluntários que produzem esta enciclopédia digital. Esta intrigante “invisibilidade” deu origem a este estudo, que pretendeu revelar a comunidade de wikipedistas em língua portuguesa: de onde são? O que fazem? Quais as idades e graus de escolaridade? Quais as motivações e constrangimentos sentidos neste processo sociotécnico? Entre outros dados recolhidos para a caracterização do perfil desta comunidade, este estudo revela a existência de baixos índices de participação das mulheres e dos povos africanos de língua portuguesa neste empreendimento coletivo.

In-situ characterization of sea state with improved navigation on an Autonomous Underwater Glider
Authors:   , Burgess Gregory A.
Published: August 2022

This thesis presents an Autonomous Underwater Glider (AUG) architecture with improved onboard navigation and acoustics-based sensing intended to enable basin-scale unattended surveys of our Earth’s most remote oceans. Traditional AUGs have long-been an important platform for oceanographic surveys due to their high endurance and autonomy, yet lack the operational flexibility to operate in many regions of scientific interest and the sensing capability to capture scientific data at the air-sea interface. Particularly of interest is the marginal ice zone (MIZ) in the Arctic and the Southern Ocean, as both are vitally important to understanding global climate trends, yet prohibitively expensive to persistently monitor with support vessels. To fill this observational gap, the sensing, navigation, and adaptability of AUGs must be improved. This is possible by employing onboard acoustic sensing for sea state observation and navigation, as well as incorporating vehicle improvements targeting maneuverability and intelligent adaptability to evolving environmental states. To enable persistent monitoring of both the water-column and air-sea interface, this thesis proposes an improved vehicle architecture for a more capable AUG, a real-time DVLaided navigation process that leverages ocean current sensing to limit localization error, and a subsea acoustics-based sea state characterization method capable of analyzing wave spectra under-ice and with zero surface expression. These methods are evaluated with respect to extensive laboratory experiments and field data collected during in-situ implementation.
High frequency acoustic propagation and modeling in stratified estuaries
Authors:   , Swanda Nicholas
Published: August 2022

Acoustic propagation measurements are made in a highly variable and stratified estuary using high frequency transducers (120kHz) on tripods placed across the main channel of the river flow. The measurements are taken in the Connecticut River across several tidal cycles, when the flood tide causes a wedge of seawater to press up the river bed, beneath the fresh water, and then be eroded and pushed back out during the ebb. BELLHOP, implemented via Matlab, is a beam/ray tracing method and is used to model the acoustic propagation in this environment using collected temperature, salinity, and depth data. Multiple modeling comparisons are done over the period of three full tidal cycles, totaling a thousand separate modeling runs and compiled into a time series. Arrival times measurements from the transducer system were able to be accurately modeled, validating BELLHOP as a useful tool in modeling this very dynamic and challenging acoustic environment.
Prosodic characteristics of key characters’ speech in M. Bulgakov’s novel «The Master and Margarita»
Authors: Fliginskih Yuliya
Published: August 2022

This article discusses the prosodic characteristics of the speech of key characters in M.A. Bulgakov’s novel “The Master and Margarita”. The work is performed in the context of the author’s dissertation.
Prosodic characteristics of the characters’ speech is an important function of the author’s commentary in the literary text, which allows to emphasize the uniqueness of each character, to reveal the individual features of the speech, emotional and mental state, temperament of characters. It also expresses the meanings that are fundamentally important for the semantics of the image. Based on this, it can be argued that the verbs of sound, adverbial and adjective side notes in the prosodic characteristics of the characters create an original manner of M.A. Bulgakov’s writings: the writer conveys the full range of feelings and moods of his characters as fully as possible, reflecting the peculiarities of oral colloquial speech as well.
In particular, the prosodic characteristics of the Master and Margarita in the novel reveal the essence of these characters, to convey the author’s intention in relation to them. So, the task of the intonation characteristics of the Master’s speech is to show his emotional instability, anxiety, which is explained by the failure with the novel (his life’s work).
In the prosodic characteristics of Margarita’s speech, two plans are distinguished: Margarita actually and Margarita the witch. This division is important, since the intonations differ significantly (which allows the author to shift the emphasis towards the heroine’s infernality in the course of the plot movement).
Special attention is paid to the analysis of lexemes that are used in the author’s comments, since they reflect the peculiarities of characters’ lexicon, contribute to the brightly changing image, while determining the self-disclosure of the character.

Published: August 2022

The scientific article comprehensively investigates the phenomenon of the diaspora from the standpoint of ethnic characteristics and concretization of the semantic boundaries of the term under study. The categorical and conceptual apparatus is analyzed from the angle of transboundary and transcultural meanings of the activities of the diasporas themselves, the national identity of their members, as well as the political and socio-economic implementation of joint activities. The author points to a rather arbitrary reference to the term "diaspora" in modern literature in the context of its role in various processes and phenomena, which only emphasizes the phenomenality of the problems raised, when researchers or entire scientific schools "put" their special meaning into the concept of "diaspora", trying to emphasize attention to the more significant from the author's point of view of one or another essential characteristic of the term.
The socio-economic potential, modern attitudes and practices in the life of diasporas are analyzed. The reasons are formulated why diasporas as subjects of economic processes can play a disproportionately large role in the economy relative to their size. The characteristics of the factors influencing the socio-economic potential of the diasporas are given. It is emphasized that the growth of the absolute and relative share of diasporas leads, respectively, to an increase in their absolute and relative contribution to the economy.
The tendency is pointed out in which the economic potential of the diaspora can become commensurate with or even exceed the economic potential of states and ethnic groups in the main territory, as well as states and ethnic groups that form the socio-cultural environment of the region. In this connection, it is concluded that the diaspora is becoming one of the most important subjects of the socio-economic processes of our time, the role and importance of which cannot be overestimated.
Distance learning is a social risk factor

Published: August 2022

The article is devoted to an actual problem – distance learning. Distance learning is a qualitatively new progressive type of training based on modern information technologies and means of communication, the rapid surge of which is caused by the pandemic that has engulfed most of the planet.
Interest in the study of the realities of post-industrial society is dictated by the need to study the nature of the transformations that occur with a person under the influence of those technological changes that have penetrated into all spheres of human existence: on the one hand, a new environment is being formed, opening up unlimited opportunities for the accumulation and transmission of information, communication in electronic network communities, on the other – these acquisitions carry potential threats and risks in both the distant and foreseeable future, and to a greater extent, in our opinion, the expected consequences of global modernization pose the greatest threat to such a specific area as education.
The subject that caused the greatest number of the most acute discussions was the impact of distance learning on the quality of training of future specialists, on the degree of development of their communication skills. The main task of the article is to justify and argue distance learning as a new form of learning, to identify its problems and positive aspects.
The article presents an analysis of theoretical approaches to distance learning for Russian and foreign researchers. Based on the results of a sociological study, the attitude of students to distance learning is revealed, and their assessment of the degree of development of their own communication skills in remote learning is obtained. The authors conclude that distance learning to a certain extent becomes a risk factor, depriving students of the opportunity to develop the qualities that modern conditions require of them: self-organization, self-control, and communication skills. Despite the fact that distance learning has become an integral part of the educational process, we are convinced that this form should only be a part, a component of the educational process, a "safety cushion" in a situation of force majeure. The leading form of educational classes at the university should remain the traditional classroom form of conducting classes as the only form that can prepare a person for life and successful functioning in a risk society
Factors of socialization and desocialization of modern youth
Authors: Tatiana Byazrova
Published: August 2022

The article discusses particularly significant aspects and factors for the socialization
and decoralization of young people in modern Russia. Today it is obvious that the radical change in the 1990s of the 20th century of the entire socio-economic system and the corresponding social relations led to a deep crisis in all spheres of vital activity of Russian society and the state. All attempts to overcome the results of the permanent crisis of recent decades did not meet expectations. Under these conditions, the problem of socialization and the asocialization of Russian youth was particularly actualized. The study of this complex and multifaceted problem was carried out through the use of such socially significant scientific methods as historical, systemic, analytical, structural-systemic, structural-functional, synergistic and phenomenological methods. This made it possible not only to analyze destructive processes in the youth environment, diagnose a high level of youth desocialization, but also to identify effective ways to correct and prevent the asocial behavior of young people.
Conclusions were drawn at the end of the article. Namely: the main reasons for the deadaption of young people are identified, the methods of resocialization of dezadapoted youth are determined, including through the formation of a motivated desire for a healthy lifestyle. A healthy lifestyle is considered in the article as one of the most effective positive factors for the resocialization of young people, along with a radical change in youth policy. Particularly important is the reasonable conclusion in the article on the formation of a new socio-historical type of youth in modern Russia with its
characteristics and value orientations that require a comprehensive and systemic study.
Physiological analysis of micropropagated banana ‘BRS Conquista’ seedlings acclimatized under different substrates and organomineral fertilizer doses

Published: August 2022

Abstract In the production of micropropagated seedlings, an important step is the exposure of plants to local environmental conditions, called acclimatization. Thus, the aim of this study was to evaluate the physiological response of banana ‘BRS Conquista’ cultivar, under different substrates and organomineral fertilizer doses during acclimatization. The experimental design used was a 3 x 5 factorial scheme (substrates x organomineral fertilizer doses), with five replicates and five seedlings per plot. The substrates used were: coconut fiber, pine bark and 100% natural mixed commercial formula. The organomineral fertilizer used was 4-14-8 at doses of 0, 1,000, 2,000, 3,000 and 4,000 g m-3. At 60 days after seedlings transplant, evaluations were performed regarding radiation incidence (Qleaf), internal CO2 concentration (Ci), stomatal conductance (Gs), transpiration rate (E), photosynthesis (A), mesophyll conductance (Gm), chlorophyll fluorescence (F), maximum leaf fluorescence in light (Fm) and leaf area index (LAI). It was observed that the pine bark substrate provided adequate physiological levels for the development of banana seedlings during acclimatization, as well as higher leaf area values. Intermediate organomineral fertilizer doses (1,000 to 3,000 g m-3) resulted in higher photosynthetic rates.

RESUMO Este artigo examina as diferenças nas receitas per capita nos estados e capitais de municípios do Brasil. Ele fornece uma visão geral teórica dos programas de equalização fiscal do Brasil (os Fundos de “Participação” estaduais e municipais). O documento fornece evidências de que esses programas não estão apenas falhando em atingir seus objetivos de equalização, mas também estão criando padrões distorcidos de receita per capita entre estados e municípios: alguns estados e municípios economicamente pobres têm receita per capita muito acima da média nacional. Esse padrão de receita per capita deve ser levado ao conhecimento do público e dos formuladores de políticas, para que eles possam: (i) avaliar melhor o desempenho dos governos estaduais e locais e (ii) avaliar melhor as propostas de revisão do sistema de federalismo fiscal do Brasil.
Kalecki: um antikeynesiano?
Authors: PAIVA CARLOS ÁGUEDO NAGEL
Published: August 2022

RESUMO Este artigo tem como objetivo investigar os determinantes da difusão limitada e da aceitação teórica do trabalho de Kalecki. Na minha opinião, as raízes da resistência a esse autor vêm da maneira incomum de ele combinar os elementos teóricos, metodológicos e analíticos em sua obra. Mais especificamente, é necessário notar que, apesar do substrato teórico de seu trabalho ser keynesiano, o padrão de investigação e exposição usado por Kalecki é estruturalista e se depara com o individualismo metodológico de Keynes. Essa contradição - o centro do diálogo geralmente difícil de Keynes e Kalecki - também limita o diálogo com as duas outras escolas que nosso autor considerou científicas em Economia, Marxismo e Econometria (neoclássica).

Resumo A máxima da investigação psicanalítica é propiciar condições para descobertas, mas não necessariamente descobrir o que se procurava. Por outro lado, no âmbito universitário, exige-se frequentemente a prévia delimitação de objetivos gerais, objetivos específicos, hipóteses e resultados esperados. Como é possível, então, diante das reivindicações clínicas e universitárias, estudar os fenômenos inconscientes de modo a não violentar a natureza do objeto de estudo? O presente artigo se propõe a realizar uma discussão teórica sobre a epistemologia da pesquisa psicanalítica e seu lugar dentro da pesquisa universitária. Conceitua-se a investigação psicanalítica como uma matriz de estratégias de investigação orientada pela prática clínica e a pesquisa. Nesse contexto, o enfoque deste artigo é direcionado ao estudo de caso.

ABSTRACT The objective of this study was to establish ophthalmic parameters in the Pomeranian dog breed. Schirmer tear test (STT), tear breakup time test (TBUTT), Jones test (JT), aesthesiometry, biomicroscopy, tonometry, non-contact specular microscopy (SM), ophthalmoscopy and ultrasonography (US) were carried out 48 eyes of 24 male and female Pomeranian dogs from a breeding kennel. Descriptive statistics was applied for data analysis. Means and standard errors found for STT, TBUT, JT, esthesiometry and tonometry were 24.310±0.448mm/min, 14.570±0.406s., 8.420±1.571min, 3.667±0.157cm and 17.960±0.697mmHg, respectively. For biomicroscopy, 43.75% of the eyes presented caruncle trichiasis, 25% chromodacryorrhea, 25% medial entropion and 10,42% distichiasis. SM showed endothelial cells density of 1958.285±36.760 cells/mm². For hexagonality, endothelial cells area and central corneal thickness were 62.229±2.183%, 519.231±9.853mm², 0.567±0.006mm, respectively. Ophthalmoscopy presented a pattern described in other breeds. Amelanotic fundus was reported in 8.33% of the eyes. The US means and standard errors for axial length of the eyeball, lens thickness, anterior and vitreous chamber depth were 16.859±0.148mm, 6.651±0.081mm, 2.673±0.091mm and 7.485±0.101mm. Mild changes in the lacrimal evaluation parameters were influenced by eyelid changes in STT type I. Increased corneal sensitivity was observed in the breed.

ABSTRACT The objective of this study was to determine relationship between Lithuanian dairy cow breed productive and reproductive traits. The study was carried out with 586 fully completed lactation cows: 184 Lithuanian Holstein (H), 320 Lithuanian Black and White (LBW) and 82 Lithuanian Red (LR) cows (291 cows in I, 149 in II and 146 in III and older lactations). Cow productivity and reproduction traits were calculated. H cows in I lactation had a lower insemination index compared to the LR, shorter calving interval (P≤0.05) and service period (P≤0.05) than LBW cows. LBW cows produced 1440.46kg more milk (P≤0.05) with less milk fat and protein content (accordingly 0.28 and 0.22 percent) (P≤0.05) compared with the LRd. The service period of LBW older lactation cows was 21.38 days longer and the insemination index was 0.68 times higher compared to the I lactation cows (P<0.05). LR cows of III and older lactations produced 3742kg more milk (P≤0.05) compared with the I lactation. All cows from 131 and more service period days produced 1420kg more milk with 0.51 percent less fat (P≤0.05) and 0.1 percent less protein than cows with the service period from 91 till 110 days (P≤0.05).

ABSTRACT This study aimed to report the prevalence of diseases in foals, patients at the Hospital Veterinário de Grandes Animais, Universidade Federal de Lavras (HVGA-UFLA), and its association with deaths and possible failures in the transfer of passive immunity (FTIP) via colostrum. Data were obtained from clinical records of horses aged between 0 and 3 months, admitted to the HVGA between January/2014 and December/2018. Descriptive analyzes of the diseases and organ systems affected were performed, as well as univariate analyzes with chi-square or Fisher's exact tests, identifying possible associations between FTIP, infectious diseases and other factors. No significant relationships were found between FTIP and infectious disease, meconium retention, sepsis, or death. However, it was shown that animals weighing between 10 and 30kg were 29.333 times more likely (95% confidence interval 1.734 - 505.951) to die than those weighing between 30.1 and 130kg. Therefore, it can be concluded that low weight is a very relevant risk factor, which may be related to the failure of postural reflexes and, consequently, to the inability to ingest colostrum, impairing the ability to respond to infectious agents.

The experiment was performed in duplicate on 5 groups of hens (14 birds/group), one control and four experimental, in which the feed was supplemented with ZooBioR2 in different doses (5.0; 10.0; 15.0; 20.0mg active substance/kg of fodder). Inclusion of the supplement in the diet have determined a significant decrease of height of intestinal villi, the depth of the crypts and the thickness of muscular layer of mucosa in the experimental groups receiving 15.0 and 20.0mg/kg. The decrease of crypts depth is an indicator of a higher rate of turn-over of epithelial tissue. The morphological changes of intestinal mucosa could be involved in a better digestibility of the fodder.

ABSTRACT This study aimed to understand the perception of veterinarians regarding monitoring blood and interstitial glucose levels in cats with diabetes mellitus and/or diabetic ketoacidosis, with emphasis on the flash glucose monitoring system (FGMS) (FreeStyle Libre, Abbott, Brazil). This research consisted of two stages. In all, 516 response forms were obtained, and of these, 480 (93%) were considered valid. In total, 333 (69.4%) veterinarians did not use the FGMS, while 147 (30.6%) did. The cost of the FGMS (116, 78%) was the greatest deterrent to acceptability. Veterinarians who use the device consider it indispensable in the hospital monitoring of diabetic ketoacidosis and a facilitator in the accurate monitoring of measurements. In addition, the preferred location for application of the sensor is the cranial lateral wall of the chest and it is quite tolerable. Monitoring a diabetic cat requires commitment from the owner and the veterinary team to ensure feline-friendly management.

ABSTRACT Chronic Progressive Lymphoedema (CPL) is a disabling disease of draft horses that affects lymphatic system function typically in the distal limbs. Deformities of distal limbs, especially of the pastern, with fibrosis and skin nodular lesions are consequences of disease progression. A 15-year-old Friesian stallion presented for evaluation with history of forelimb enlargement and nodule formations distal to the carpus for four years. Simple radiographs showed soft tissue nodular lesions and venous contrasted radiography showed intense enlargement of II common digital palmar vein of both forelimbs. Tissue culture tests revealed Streptococcus equi and Proteus mirabilis isolation and skin scraping test identified Chorioptes bovis mites. Histological examination revealed perivasculitis and lymph vessels distention. History, clinical and histological findings, and complementary exams suggested CPL diagnosis. We were unable to find previously published cases describing this disease in Brazil, where the increasing number of draft horses requires attention to this problem. The correct and early diagnosis substantially delays disease progression. Therefore, we highlight the need for nationwide propagation of these data to ensure better diagnosis and early treatment of future CPL cases.

ABSTRACT The aim of this study was to evaluate the reproductive performance of red-winged tinamous in captivity using different mating systems during three breeding seasons. The data were collected from August to March during three breeding seasons of the species. Ten couples and four groups of red-winged tinamous were randomly selected for formation of the monogamous and polygynous mating system, respectively, with egg collection from both systems. The traits evaluated were number of eggs per female, egg breaking and egg fertilization. Data were statistically analyzed by the least square method and logistic regression. Animals in couples mating strategy were superior (P<0.05) in terms of number of eggs per female compared to the group mating strategy. High egg breaking rate (P<0.05) in the red-winged tinamous groups was observed. Eggs of animals in couples mating strategy were 5.24 and 11.5 more likely to be fertilized than those of group strategy in two breeding seasons. In general, the reproductive efficiency in terms of low egg breaking, high egg production and fertility was observed for red-winged tinamous from the monogamous mating system.

ABSTRACT A 14-month-old female Texel sheep that came from a herd made up of 19 animals showed haemoglobinuria, apathy, and anorexia, and died two days after the start of the clinical signals. The sheep remained in a natural grassland, where trailers were repaired, and multiple copper wires were deposited on the pasture. The animal had tachycardia, tachypnoea, pale mucous membranes, groaning pain on abdominal palpation, circling, head pressing, intensely hemolyzed plasma, and intense azotaemia. The necropsy showed focally extensive oedema in the inguinal and medial region of pelvic limbs, kidneys dark brown, and liver diffusely yellow with an evident moderate diffuse lobular pattern. The abomasum had a considerable amount of enameled material of thickness, firm to the cut, with 1-5 mm (copper wires). Histopathological examination showed marked diffuse tubular and glomerular coagulative necrosis in the kidneys, in addition to neutrophils, macrophages, lymphocytes, and plasma cells with moderate multifocal nephritis. The liver showed centrilobular necrosis, moderate hepatocellular edema, multifocal cholestasis, and in the lungs and brain mild to moderate diffuse edema. Copper content in the frozen liver (in natura) reached 1,598 mg/kg. Copper mesh ingestion led to sheep poisoning, which in this case was considered an atypical form of chronic primary copper poisoning.

ABSTRACT Objective: To characterize and identify depressive symptoms, anxiety, and stress associated with the COVID-19 Infodemic in the elderly from São Paulo. Method: Exploratory and cross-sectional study with the elderly in the capital of São Paulo who had internet access. The sociodemographic profile, the COVID-19 infodemic, depressive symptoms, stress, and anxiety were analyzed. Results: A total of 411 older people participated in the study. There was a predominance of women (76.4%), with higher education (57.9%), using private health services, and with little income variation. Older people were more exposed to news or information about COVID-19 on the internet (45.3%), followed by television (34.5%), and radio (11.4%). The average stress was 19.96 points; 33.1% had anxiety, and 39.7% had depressive symptoms. The greater the number of people living with the elderly, the greater the stress (p = 0.001) and anxiety (p = 0.02). The hours of exposure to information on the internet led to stress (p = 0.001), depressive symptoms (p = 0.02), and anxiety (p = 0.02) in the elderly. Conclusion: During the pandemic, exposure to information on the internet triggered anxiety, stress, and depressive symptoms in the elderly. The findings highlight the need for multi and interdisciplinary interventions to mitigate such repercussions on the elderly’s health.
A crítica da economia política como método: alguns elementos para investigação nas ciências sociais
Authors: Santos Nivalter Aires dos
Published: August 2022

Resumo: Objetivamos, com este artigo, lançar luz sobre alguns elementos da crítica da economia política como método, que favoreçam o desenvolvimento de pesquisas no campo das ciências humanas e sociais. Para isso, partimos dos escritos produzidos por Karl Marx e Friedrich Engels — aos quais complementamos com os avanços teóricos produzidos por alguns intelectuais marxistas ao longo do último século e meio — num esforço de evidenciar princípios importantes para investigação. Destacamos, como aspectos relevantes do trabalho, que a pesquisa social deve ter fundamento no real concreto, cabendo ao pesquisador descobrir a mediação entre aparência e essência através de aproximações sucessivas de reconstrução, no pensamento, da totalidade do fenômeno analisado, a partir de seu próprio movimento, em vista da transformação social.

Resumo Este artigo tem como objetivo apresentar as correlações entre as políticas de mercados institucionais, quais sejam: o Programa de Aquisição de Alimentos (PAA), Programa Nacional de Alimentação Escolar (PNAE) e a temática do desenvolvimento sustentável a partir da revisão bibliográfica de relevantes obras que abarcam o tema. Para isto, fez-se uso da Sociologia Ambiental do Direito (SAD), perspectiva de análise que contempla o entendimento dos fenômenos sociojurídicos a partir da ótica ambiental. O trabalho estrutura-se em: a) introdução, que apresenta o contexto de surgimento e atual situação das políticas abordadas; b) desenvolvimento, de natureza conceitual, que busca a compreensão da SAD, do PAA e do PNAE, em suas mútuas interações, à luz das referências teóricas selecionadas; c) considerações finais, com a análise dos resultados alcançados, mediante a conexão dos elementos anteriormente suscitados e que, eventualmente, venham a contribuir para futuras análises do PAA e do PNAE, importantes instrumentos do desenvolvimento sustentável.
Política agrária no primeiro Plano Diretor da SUDENE: fome, abastecimento e política
Authors: Pinto Gustavo Louis Henrique
Published: August 2022

Resumo No primeiro Plano Diretor da SUDENE (1961-1963), sob coordenação de Celso Furtado, a questão agrária constituiu importante paradigma para a construção de uma política de desenvolvimento para a região Nordeste. Este artigo busca analisar a política agrária sistematizada no documento do Anteprojeto do Plano Diretor em suas seguintes fases: o diagnóstico da crise social e efeitos da seca, a proposta de reestruturação agrícola direcionada à produção de alimentos e combate à fome, e a política de abastecimento e colonização para diminuição do deslocamento populacional forçado. Esses elementos constituem a base do prognóstico da política agrária da SUDENE e da proposta de transformação estrutural para redução das desigualdades sociais, para uma nova agricultura e um novo agricultor. O plano encaminhado pela SUDENE resultou da pactuação intraelites do Conselho Deliberativo da SUDENE, entre governadores e representantes de ministérios, e mesmo representando a “medida do possível” para a estrutura agrária, conheceu sua derrocada política.
Vamos, sim, falar da fome!
Authors: Azevedo Darana Carvalho de
Published: August 2022

Resumo A fome é uma das manifestações da insegurança alimentar e nutricional, expressão da questão social oriunda da desigualdade social desencadeada pelo modo de produção capitalista, detentora de uma lógica de valorização do capital que subordina o valor de uso ao valor de troca, estabelecendo um modo de vida sem sentido à medida que se trabalha para a geração de lucro e não para suas reais necessidades humanas. Partindo desse pressuposto, o presente artigo analisa como esse processo de valorização reflete na Segurança Alimentar e Nutricional, sob os aspectos de: produção e distribuição das commodities; custos da alimentação; condições socioeconômicas; e questões culturais. Os resultados demonstram que essa lógica de valorização afeta a produção, distribuição e consumo dos produtos alimentares, imprimindo consequências na disponibilidade dos produtos, na composição nutricional, na qualidade sanitária, nos padrões de consumo, na capacidade de compra, nas preferências alimentares e no uso sustentável dos recursos naturais.
