Published: March 2022

ABSTRACT This study determines the degree of hydrological stress (HS) on the Goiana River basin in Pernambuco, a state in northeastern Brazil. The hydrological stress index is obtained by comparing the values of the surface permits with the limits granted by the managers. The results pointed to a situation of “High” hydrological stress (HS) in the Nazaré da Mata sub-basin, with approximately 94.76% of the grantable flow being used. In the Caricé sub-basin, the degree of hydrological stress was considered “Medium,” with about 31.77% of available flow being granted. The other sub-basins had results considered to be “Low” hydrological stress (between 0% and 25%). Given these results, this study emphasizes the importance of constantly monitoring data on the demand for water use in the region and improving the criteria management bodies follow when granting permits.

Published: March 2022

Resumo Introdução Os Serviços Residenciais Terapêuticos (SRTs) representaram grande avanço no processo de desinstitucionalização brasileiro. Porém, faz-se necessário investir nas discussões que contribuam para que esses dispositivos sejam espaços potentes de habitação e de valorização da subjetividade de seus moradores. Objetivo Investigar a participação e o exercício da autonomia dos moradores de SRTs do tipo II, a partir da sua própria percepção. Método Trata-se de pesquisa qualitativa, exploratória e documental, realizada por meio de coleta de dados documentais e de entrevistas. Participaram do estudo 8 moradores de SRTs tipo II. O material produzido foi submetido à análise temática. O conceito do Cotidiano embasa o estudo, a partir das perspectivas da terapia ocupacional, da Teoria do Cotidiano de Agnes Heller e da Reabilitação Psicossocial. Resultados A institucionalização prolongada está estreitamente relacionada com a pouca participação e autonomia dos participantes em seu cotidiano, com a pouca ou inexistente apropriação do SRT e com a percepção que eles têm de si como pacientes, e não como moradores de suas casas. O exercício da autonomia pelos participantes é relacionado ao seu desempenho e funcionalidade na realização das atividades diárias e à assistência integral pré-estabelecida para o SRT tipo II. Conclusão Concluiu-se que a terapia ocupacional traz contribuições fundamentais relacionadas à participação e à autonomia de pessoas que, devido às institucionalizações prolongadas, encontram-se em situação importante de cronificação. A participação nas atividades cotidianas e a possibilidade do exercício de autonomia no SRT são o primeiro passo rumo à definitiva possibilidade de inclusão social de seus moradores.

Resumo Este texto apresenta uma atividade grupal desenvolvida durante a epidemia de covid-19 em espaço virtual, com 13 participantes, estudantes e professores universitários. O objetivo foi oferecer um espaço de escuta protegido e criar estratégias para enfrentar a angústia e o medo decorrentes da epidemia. A ferramenta metodológica utilizada foi a intervenção grupal, realizada entre maio e agosto de 2020, que operou como uma rede de conversação. No grupo, produziu-se um diálogo horizontal com temas escolhidos conjuntamente e buscando soluções compartilhadas para diversos problemas. Este artigo analisa o diálogo ocorrido nos encontros em que se falou sobre o medo. Neles, os(as) participantes identificaram o medo da morte e da perda de pessoas amadas como aquele que desperta maior sofrimento, acentuado quando as pessoas estão distantes geograficamente. A avaliação mostrou que os encontros e os diálogos produziram alívio e bem-estar, e que trabalhar em plataforma virtual não constituiu empecilho à comunicação. Grupos de intervenção desenvolvidos em espaço virtual compõem metodologias de baixo custo, porém potentes, fáceis de operar e possíveis de serem nucleadas nos mais diversos coletivos.

Abstract A total of 132 flounder specimens (60 Paralichthys isosceles, 36 Paralichthys patagonicus and 36 Xystreurys rasile) were collected off the coast of the state of Rio de Janeiro, Brazil. The fish were measured, necropsied, and had their organs investigated for hemiurid and lecithasterid digenean trematodes and camallanid and cucullanid nematodes. Taxonomic identification of the parasites was based on morphological and morphometric characters and was conducted using bright-field and scanning electron microscopies. The trematodes Lecithochirium monticellii and Aponurus laguncula were found parasitizing P. isosceles, P. patagonicus and X. rasile while the nematodes Procamallanus (Spirocamallanus) halitrophus and Cucullanus bonaerensis were found parasitizing P. isosceles and X. rasile and P. isosceles, P. patagonicus and X. rasile, respectively. Parasite indices of prevalence, mean intensity, mean abundance, and range of infection, as well as infection site, were evaluated for each parasite species. This study allowed to evidence the first occurrence of P. patagonicus by L. monticellii; X. rasile by A. laguncula and P. (S.) halitrophus; and P. isosceles and P. patagonicus by C. bonaerensis in the Western South Atlantic Ocean.

Characteristics of Triple Seronegative Myasthenia Gravis: A Single Center Experience
Authors: Morena Jonathan , Jiang Benjamin , Freimer Miriam , Hoyle Joseph , Elsheikh Bakri , Arnold David , LoRusso Samantha
Published: March 2022

Background: There is variability in the literature regarding the characteristics of triple seronegative myasthenia gravis (SNMG) patients. Most studies were performed before LRP4 antibodies were discovered, and characterizations of triple seronegative patients are lacking in the literature.

Methods: We retrospectively investigated patients diagnosed with myasthenia gravis (MG) at Ohio State University from 2009 to 2019. Triple SNMG was defined by a history and examination that was consistent with MG and positive SFEMG, RNS or edrophonium testing, but negative serology for AChR, MUSK, and LRP4 antibodies.

Results: A total of 210 AChR+, 9 MuSK+, 6 LRP4+, 9 double SNMG, and 21 triple SNMG patients were reviewed. Triple SNMG patients required significantly fewer immunosuppressive agents compared with AChR+ patients (p=0.0001) and a trend towards a less frequent history of hospitalizations, myasthenic crises and intubations compared to all antibody positive groups. Triple SNMG patients had a significantly higher frequency of ocular disease (33%) compared to AChR+ patients (13%) (p=0.0250). One triple and one double SNMG patient had thymic hyperplasia and improved after thymectomy. 11 triple SNMG patients had negative genetic testing for CMS.

Conclusion: Our results further elucidate the clinical characteristics of triple SNMG, which include the predominance for ocular disease and a less severe disease course. Although likely rare, investigation for thymic pathology should be a consideration even in SNMG, and thymectomy should be considered when there is thymic pathology. We did not find alternate diagnoses in SNMG patients and thus ancillary testing should be considered in carefully selected patients for cost-effective care.

Introduction. Modern technologies allow the synthesis of nanostructured coatings from multiple chemical elements to combine different physical, mechanical, and chemical properties in one coating. Promising in this respect are coatings formed via layer-by-layer deposition of zirconium and chromium nitrides. The deposition of various chemical elements on various substrates requires separate studies in order to produce high-strength and wear-resistant coatings. The purpose of this work is to study the structural-phase state and mechanical properties of ZrCrN coatings formed by plasma-assisted vacuum arc evaporation. Materials and methods. The investigation is performed on specimens comprising VK8 hard alloy substrates with zirconium and chromium nitride coatings as well as with multilayer ZrCrN coatings. The methods used are confocal laser scanning microscopy, X-ray diffraction analysis, high-resolution scanning electron microscopy, nanoindentation, and scratching. Results and discussion. The experimental results obtained showed that the mode of multilayer ZrCrN coating evaporation greatly affects the structure, morphology, surface roughness, and mechanical properties of the coatings. In particular, by varying the substrate rotation speed during coating deposition it is possible to control the deposition time of each coating layer and thereby modify the layer properties. Conclusions. The investigation results showed that variation of the evaporation conditions allows one to obtain a ZrCrN coating with a high nanohardness of 45 GPa on a VK8 alloy substrate. Analysis of mechanical test results indicate good adhesion between the studied coatings and the substrate. Scratch tests revealed that fracture of CrN and ZrN coatings occurs by the cohesive mechanism, and the surface of ZrCrN coatings exhibits uniform scratches without any signs of fracture. Based on the results obtained, ZrCrN-2…ZrCrN-4 coatings can be recommended for use as hard and wear-resistant coatings.

The application of artificial intelligence in the development of а decision support system for the implementation of transport traffic is presented. Such systems are designed to adjust the schedule of objects in cases of unforeseen situations. A fully connected artificial neural network with several hidden layers, trained using a genetic algorithm, is used. During training, the functionality that characterizes the deviation from the specified schedule is minimized. Railway traffic is one of the most important types of transport in Russia. Every year it becomes more and more intense, the density and volume of both cargo and passenger traffic increases. As a result, the requirements for the exact execution of the planned traffic schedule increase, since any deviation leads to significant penalties due, for example, to an increase in train delays, their cancellation, etc. The work of a dispatcher, a person who controls railway traffic, is quite time-consuming and becomes more difficult every day, so the development of dispatcher assistance systems is one of the most relevant areas in control automation in this area. At the same time, the existing high requirements for traffic safety, which impose additional restrictions, finally lead to the fact that in this kind of system, the final decision is left to the person, and computer development has a recommendatory character. This article describes the artificial intelligence apparatus in the form of training neural networks using a genetic algorithm to build an automated dispatcher that corrects movement.
The Influence of Ways of Organizing Learning Interactions on the Development of Communicative and Reflexive Abilities of Children 6—10 Years Old
Authors: Rubtsov V.V. , Ulanovskaya I.M.
Published: March 2022

The features of the development of communicative and reflexive abilities of children aged 6—10 years, depending on the ways of organizing educational interactions, are discussed. Basic social competencies defined by the requirements of the current Federal State Educational Standard of Primary General Education are considered as indicators of the development of abilities in the learning environment. Based on the selected indicators, a variant of the “Puzzle” diagnostic method has been developed, which allows to study the relationship between the development of social competencies in younger schoolchildren, and the joint way they perform while solving experimental problems. A comparative analysis of students' social competencies allows to prove the influence of ways of organizing educational interactions on the development of communicative and reflexive abilities of primary school children.

Published: March 2022

The purpose of our work was to study the factors that determine the effectiveness of model acquisition in solving inquiry-based problems (balance scale problem). An experimental lesson, which we conducted in the 4th grade, revealed the differences in the way children refer to a general method of assessing equilibrium provided by the teacher. At the end of the lesson a test was conducted. Its results allowed us to divide the participants (22 students) into two groups according to their success, which depended on whether they applied the model, that they had tried out during the lesson. The performance of students in the «Transpositions» test (A.Z. Zak), which was designed to identify students' approach to solving inquiry-based problems («empirical» or «theoretical»), showed significant differences in the level of reflection, analysis, and planning between the two groups (according to the Mann-Whitney criterion p<0.01). These results and data analysis allow us to connect the success of the modeling means' acquisition to the predominance of either an «empirical» or a «theoretical» approach to mastering ways of solving a new problem.
Testing the Limits of Natural Transformation
Authors:   , Piazza Danielle Renee , Mell Joshua Chang , Xiao Ming
Published: March 2022

Naturally transformable bacteria actively take up intact DNA molecules from their environment, which can be incorporated into their own chromosomes via homologous recombination. Analogous to sex in eukaryotes, natural transformation allows bacteria to rapidly adapt to new environments by acquiring traits from their dead relatives - for example, hastening evasion of host immunity or spreading antibiotic resistances. Although mechanistic biases are known to arise during meiotic recombination in sexual eukaryotes, little is known about such biases during bacterial natural transformation, nor how they affect pathogen evolution. Here, we used Haemophilus influenzae as a model to investigate the genome-scale consequences of natural transformation by varying the size and divergence of taken up donor DNAs. Deep sequencing reveals >100-fold variation in transformation rates at different loci when donor DNAs were short, and this effect was partly explained by local sequence similarity between donor and recipient. Identified hotspot and coldspots of transformation are also present in natural populations, and were validated by an allele-specific droplet digital PCR assay (ddPCR), developed as an independent tool to measure these loci with more flexibility, reproducibility, and cost effectiveness compared to deep sequencing efforts. We also found that single cells could take up and recombine exceptionally long DNAs spanning >10% of chromosome length. Surprisingly, co-transformation was mostly unimpaired across inversions and other rearrangements, though the breakpoints of such structural variants often acted as barriers. We also present novel applications of DNA optical mapping, which could disentangle transformation itself from its consequences on fitness. Genetic incompatibilities, which result in altered fitness of the recombinants, require addressing to fully understand the consequences of genetic divergence or marker selection on fitness. We developed methods to chemically label donor DNA, transform it into recipient chromosomes, and then use OM to detect individual transformation events at a single-molecule level with extremely high physical coverage (>100K-fold). In the future, this will allow us to make genome-scale transformation maps while minimizing fitness effects of recombination and without relying on genetic variation. Overall, our results show that H. influenzae can take up and recombine much larger molecules than previously expected and underline the importance of bacterial recombination in the evolution of pathogenesis. These findings have expanded the field of sequencing of bacterial recombinants and provide new opportunities to study population level transformation biases. This work suggests new mechanistic investigations, will inform genomic epidemiology studies, and advances the search for novel vaccine and drug targets.
Disrupting Youths' Education

Following an arrest, many students transfer to a new school. In fact, 22 states require schools to transfer arrested students. Given that students who transfer schools have a higher risk for academic challenges linked to dropout and/or delayed graduation, transfer following arrest may prevent academic progress for justice-involved youth. Data from 1,021 Philadelphia students arrested in schools during the 2013-2014 school year were examined, comparing graduation likelihood, dropout likelihood, and time to dropout among students who transferred to a new school within two months of arrest and those who did not transfer. Results from logistic regression analyses indicated no significant differences between transferred and non-transferred students in their likelihood of graduation or dropout. Stratified Cox proportional-hazards regression results revealed that transferred students had a significantly longer time to dropout following arrest than did their non-transferred peers. Implications for stakeholders and future research directions are discussed.

O objetivo deste estudo foi avaliar o momento ideal de dessecação e de que forma diferentes princípios ativos influenciam a produtividade e a qualidade física e fisiológica de sementes de feijão-preto, cultivar BRS Esteio. O experimento foi conduzido na safra 2018/2019, no município de Pato Branco, Paraná. A semeadura foi realizada no dia 07/11/2018 e o delineamento experimental adotado foi de blocos ao acaso (DBA), com quatro repetições. Os tratamentos foram arranjados em esquema fatorial 4 x 4 (quatro herbicidas x quatro épocas de aplicação). A aplicação dos dessecantes foi realizada quando a cultura apresentou 60%, 70%, 80% e 90% das vagens no estágio de maturação de campo. E os princípios ativos e doses utilizadas foram: diquate (400 g de i.a. ha-1), glufosinato – sal de amônio (400 g de i.a. ha-1 + óleo mineral), saflufenacil (49 g de i.a. ha-1) e glifosato potássico (1.240 g de i.a. ha-1). As avaliações pós-colheita foram as seguintes: peso de mil sementes (g), produtividade (Kg ha-1), teste de germinação (%), teste de envelhecimento acelerado (%) e comprimento de parte aérea e raiz de plântulas (cm). Independente do princípio ativo utilizado, visando a produção de sementes, a dessecação da cultivar de feijão-preto BRS Esteio, deve ser realizada quando 60% das vagens se encontram no estágio de maturação de campo. Além disso, as sementes dessecadas com glufosinato – sal de amônio, resultaram em sementes mais pesadas e em plântulas mais vigorosas, contrariamente ao observado para o glifosato potássico que reduziu o vigor de plântulas.

ResumoEste estudo de caso tem como objetivo, a partir das narrativas autobiográficas de acadêmicos de uma universidade privada, compreender quais foram as influências e motivações que levaram os mestrandos a ingressar em um programa de pós-graduação em Ensino de Ciências e Matemática. Para isso, utilizamos a escrita de si como metodologia, via cartas. As análises ocorreram em dois movimentos distintos e complementares: um a partir da constituição e caracterização do curso em foco e o outro se pautou nas possíveis interpretações das narrativas autobiográficas. Foi possível identificar dentre os discursos as categorias definidas, por nós, como crescimento pessoal, progressão profissional, obtenção de título, progressão acadêmica, contribuição social e ser docente. Transpassam as narrativas dos mestrandos um processo de valorização do mestrado e de ser mestre que remetem aos principais tipos de capital definidos por Thompson (2011): capital econômico, capital cultural e capital simbólico. Concluímos, a partir dessa pesquisa, que os mestrandos em foco são conscientes que são sujeitos inacabados, inconclusos, e que na relação com o outro e com o mundo, almejam o mestrado para reconhecimento, poder, melhores empregos, titulação e ampliação de seus conhecimentos e de sua concepção de mundo.

AbstractThe autobiographical narratives of academics from a private university help us to understand what were the influences and motivations that led the Master's students to enter a postgraduate program in Science and Mathematics Teaching. We used the self writing as methodology, via letters. The analyzes took place in two distinct and complementary movements: one from the constitution and characterization of the course in focus and the other was based on the possible interpretations of the autobiographical narratives. It was possible to identify among the speeches the categories defined by us, such as personal growth, professional progression, obtaining a title, academic progression, social contribution, and being a teacher. The narratives of the Master's students pass through a process of valuing the Master's and being a Master that refers to the main types of capital defined by Thompson (2011): economic capital, cultural capital, and symbolic capital. We conclude, from this research, that the Master's students are aware that they are unfinished, unfinished subjects, and that in relation to the other and the world, they aim for the master's degree for recognition, power, better jobs, qualification, and expansion of their knowledge and their conception of the world.

Published: March 2022

The article presents a clinical case of a 78-year-old female patient with a clinical picture of vasospastic angina during the capecitabin treatment. The issues under discussion include difficulties of diagnosing vasospastic angina, a potential danger and incidence of coronary vasospastic reactions during chemotherapy with drugs of this group, and current approaches to prevention and correction of fluoropyrimidine cardiotoxicity. The presented clinical case confirms that vasospasm is a manifestation of capecitabin cardiotoxicity. This case also illustrates the importance of interaction and co-ordination of the work of oncologists and cardiologists at all stages of care of oncological patients.

Authors: Tulunay Kaya Cansin , Gerede Demet Menekse , Akhundova Javidan
Published: March 2022

Aim    Energy drinks (ED) contain high levels of caffeine and taurine and are associated with several cardiovascular effects. We investigated acute effects of consuming low caffeine and taurine content ED on left ventricular (LV) and right ventricular (RV) function assessed by conventional and two-dimensional speckle tracking echocardiography.Material and methods    In this crossover study, 34 healthy adults, age 19–48 yrs, drank an ED containing 53.25 milligrams of caffeine, 284 mg of taurine, or an equal volume of control drink (CD) on two separate sessions, 7–10 days apart. Standard echocardiographic and speckle tracking imaging were performed before and 60 min after consumption of the study beverages.Results    Compared to CD, ED caused a significant increase in tricuspid annular plane systolic excursion (p=0.04) and RV systolic wave velocity (p=0.01) with no effect on global longitudinal strain when compared to CD. LV systolic function was not altered, but mitral early diastolic velocity by tissue Doppler imaging was significantly higher (p=0.031), and early diastolic strain rate, as measured by speckle tracking echocardiography, was significantly lower (p=0.022).Conclusion    Reduced caffeine and taurine content ED does not affect LV systolic function, but increases RV longitudinal contractility and improves LV early diastolic filling.

Acute renal failure in scrub typhus patients
Authors: Manish Abhinav , Pamdey Pratibha
Published: March 2022

Scrub typhus, a bacterial infection caused by Orientia Tsutsugamushi (formally Rickettsia) due to bite of the mite, and is increasing every year, and becomes a important cause of acute febrile illnesses. Due to lack of specific diagnostic facilities in most rural setups and non-specific clinical presentations, it becomes a challenge for clinician to correctly diagnose it on clinical examination. Clinically it presents with non-specific febrile illnesses with constitutional symptoms such as fever, rash, myalgia and headache or with organ dysfunction involving kidneys, lungs, liver, central nervous system or with circulatory collapse with hemorrhagic features. Eschar is the characteristic lesion which is present at the bite site of mite. Later an ulcer with black necrotic centre and regional lymphadenopathy occurs. Renal involvement in the form of Acute Renal Failure is seen very occasionally in these patients. So this Case-control study is designed for a period of six months which are october-2018 to march-2019, comparing 80 ELISA(Enzyme Linked Immune Sorbent Assay) confirmed cases of scrub typhus and 50 healthy controls. Statistically significant difference in Urea, Creatinine and Uric acid levels were found between two groups, using 't'-test with the significance value of P<0.0001.

Published: March 2022

Melasma, also called ‘chloasma’, is a common skin condition of adults in which light to dark brown or grayish pigmentation develops, mainly on the face. Although it can affect both genders and any race, it is more common in women. Melasma is an acquired pigmentary disorder described as symmetrical blotchy or splotchy hyperpigmented macules and patches.

The aim of this study was to investigate thyroid profile with anti TPO and iron, uric acid level, in male and female patients.

It is a cross-sectional observational study done on 76 females and 25 male who were diagnosed with melasma and thyroid profile with anti TPO, serum iron and uric acid levels were measured.

In our study females were more affected then males. In females Mean ± SD value of serum TSH (5.1±2.51) and anti-TPO (11.2±3.1) levels were increased when compared to males(4.9±2.54) and (9.2±1.9). Serum iron value was low in females (83.7±30) than males (90±29). All biochemical parameter were not significant but anti TPO and FT3 showed significant (P<0.001) in female with compared to male. Serum uric acid (3.56±0.77) and serum iron (83.7±30) Mean± SD value was low in melasma females than males which is not significant. Females Mean±SD value of T3 (1.30±0.62) and T4(6.8±1.9), FT4 (1.2±0.44) were non significance showed than compared to males and not significant to males T3 (1.33±0.66) and T4(7.1±1.6), FT4 (1.3±0.67) respectively.

Melasma is more severe in females than males. Thyroid profile is not the accurate parameter but anti TPO, and iron level are predictive marker of melasma.

Women's health is one of the main goals of social and economic development of societies; therefore, problems and diseases compromising women's physical and mental health, such as premenstrual syndrome (PMS), are among health priorities.

To estimate and compare the serum levels of calcium and magnesium in subjects with pre-menstrual syndrome and subjects without premenstrual syndrome during pre-and post-menstrual phases.

: Healthy women (intern students, hospital staff, non-teaching staff, class 3 and class 4 staff) in the age group of 18-26 years having regular menstrual cycles for the past 6 months were included based on inclusion and exclusion criteria. PMS was diagnosed based on ACOG criteria. 5 mL of venous blood sample was collected in red stoppered plain tube and used for estimation of serum calcium and magnesium levels during premenstrual phase of menstrual cycle.

We found that there was no significant difference in the serum calcium levels between cases and controls, but there was significant difference in serum magnesium levels between the cases and controls.

Several factors like culture, socioeconomic status, cigarette smoking, alcohol consumption, exercise, dietary habits, age of menarche etc. have also been implicated. Prolonged stress exposure is believed to lead to persistent malfunctions of neuroendocrine system and cause PMS. Lack of micronutrients and certain hormonal agents and are also implicated in the development of PMS. We strongly recommend Lifestyle modifications which include mind-body approaches, aerobic exercise, and supplementation with vitamins, minerals, and complex carbohydrates. Early nutritional supplementation of with the diet rich in these minerals will be effective as preventive and therapeutic strategy.

Rheumatoid arthritis is the most common chronic, progressive systemic inflammatory arthritis of unknown cause. It affects approximately 1-2% of the population worldwide. It is a form of autoimmune disease principally synovial tissues. As the pathophysiology involves affecting cell mediated immune response, adenosine deaminase may have a role in rheumatoid arthritis. As it involves bones and joints, it is likely that it alters the levels of Serum Calcium, Phosphorus and Magnesium as well as Alkaline Phosphatase which may be helpful in diagnosis or management of the disease.

1. To evaluate the role of serum adenosine deaminase (ADA) as a marker of cell mediated immunity in Rheumatoid Arthritis. 2. To estimate serum alkaline phosphatase, calcium, phosphorus and magnesium as prognostic markers of Rheumatoid arthritis

A cross-sectional, case control study with convenient sampling was undertaken after Institutional Ethical Clearance & informed consent. 30 patients of Rheumatoid Arthritis presenting to the orthopaedic outpatient department of Owaisi Hospital and Research Centre, Hyderabad were taken as cases along with an equal number of age and sex matched controls from January 2021 to June 2021.

ADA levels were estimated by colorimetric assay on ErbaChem 7 semiautoanalyser. Serum Alkaline phosphatase, Calcium, Phosphorus and Magnesium were estimated on Cobas C311 autoanalyzer.

There was a significant increase in levels of Adenosine Deaminase, Alkaline Phosphatase and Serum Phosphorus, while the levels of Calcium and Magnesium were significantly reduced in rheumatoid arthritis

ADA as a marker of cell mediated immunity reflects monocyte / macrophage activity and was increased in our study suggesting immunological and inflammatory process in the pathogenesis of Rheumatoid Arthritis (R.A). It can be used as a non invasive marker of chronic inflammation and may provide additional information about disease prognosis.

Increased levels of Alkaline Phosphatase and Phosphorus associated with low Calcium and Magnesium suggest increased bone resorption in R. A and are useful as markers of disease activity.
Distance Education in Veterinary Medicine: History, Current Situation, and Future Perspectives (a Systematic Review)
Authors: Salazar José Miguel Velásquez , Miglino Maria Angelica
Published: March 2022

Technology has revolutionized education making it more accessible, overcoming time and space barriers, and reducing costs for undergraduates and professionals. In veterinary medicine as well as in other knowledge areas, distance education has evolved, going to the forefront of technological advances. Today, many tools, courses, and online platforms are available to facilitate and enhance the teaching-learning process for institutions and students. However, because of the Covid-19 (Sars-CoV-2) pandemic, educational institutions and veterinary medicine students around the world were forced to use distance education tools, many of them without being prepared or knowing the tools available or not having the necessary tools. In this sense, seeking to offer students and educators information about the evolution of distance education in veterinary medicine, its current situation and available tools, it was made a systematic review using the databases Science Direct, Scopus and Google Scholar, gathering more than 244 journal articles, and finally 116 articles were selected. The selected articles were analyzed for the history, platforms, and resources available, difficulties, current situation, and future perspectives, as well as the advantages and need of distance education in the actual pandemic situation. We can conclude that distance education is currently an indispensable tool in veterinary medicine, complementing face-to-face courses and reducing costs. This has led to the development of several platforms, applications and online educational resources that facilitate and enhance the teaching-learning process for educational institutions, veterinary students, and professionals.

Pineapple Drying Analysis in Packing Plants Through Computational Fluid Dynamics
Authors: García Alexis Cordovés , Rodríguez Alexis Cordovés , Buñay Karla Tatiana Núñez , Aleaga Arlys M. Lastre , Lorente-Leyva Leandro L.
Published: March 2022

The aim of this research is to determine the average fluid velocity values and the average total pressure at the outlet of the ventilation system conduit for the drying, by air impulsion, of pineapples in packing plants, in order to ensure the required humidity level of the crown for its proper packaging. The CAD model of the air conduction was obtained in Solidworks and Computational Fluid Dynamics (CFD) techniques were applied to simulate the performance of the ventilation system. Air was indicated as the type of fluid, and an internal analysis of the pipe with roughness Rz = 3.2 μm. As a computational domain, the pipeline was established, from the connection to the fan to the outlet diffuser. As boundary conditions were established; a W and Z Manufacturing regenerative fan at the inlet of the flow pipe 618,439 m3/h, and at the outlet of the pipe the value of atmospheric pressure. As a result of the simulation, an average velocity value at the diffuser outlet of 127.294 m/s was obtained, higher than the required 96.06 m/s. An average total pressure value of 111718.73 Pa was obtained in the conduit suitable for the proposed purposes. For the conveyor belt, it is recommended to use, in each row of pineapples, the simulated fan with a simple diffuser with a rectangular section of 1 x 20 cm, or a regenerative fan with a flow of 1248.77 m3/h and a diffuser with two-outlet bifurcation.

Authors: Zamecka-Zalas Olga
Published: March 2022

Edukacja ojczysta dziecka oraz przygotowanie w tym celu kadr pedagogicznych na uchodźstwie były nadrzędnym zadaniem polskich środowisk oświatowych przebywających po drugiej wojnie światowej w Wielkiej Brytanii. Gdy wycofane zostało uznanie dla rządu polskiego w Londynie, to właśnie działacze nauczycielscy przejęli ogromny trud utrzymania polskiego szkolnictwa, a tym samym przeciwdziałania wynarodowieniu młodego pokolenia Polaków. Celem artykułu jest ukazanie sytuacji nauczycieli w systemie organizacyjnym polskiego szkolnictwa oraz roli Zrzeszenia Nauczycielstwa Polskiego Zagranicą, które stworzyło podwaliny pod system szkół przedmiotów ojczystych. W artykule ponadto ukazano cele działalności nauczycieli, którzy byli ogarnięci wielką społeczną pasją i umiłowaniem tradycji, różnorodne formy kształcenia oraz ich ogromną rolę w wychowaniu dzieci w polskiej kulturze i tradycji.

Authors: Kontorovich V. A. , Philippov Yu. F.
Published: March 2022

A comprehensive analysis of geophysical data was carried out and a model of the deep structure of the Yenisei–Khatanga regional trough was constructed. A distinct platform appearance of the Neoproterozoic-Paleozoic sediments, the synchronous occurrence of ancient and Mesozoic sedimentary complexes in the axial most submerged part of the Yenisei–Khatanga linear depression. A wide territorial distribution of trap magmatism was revealed, which is not localized in the linear structure of the trough. It is concluded that the formation of the Yenisei-Khatanga regional trough is not associated with the Late Permian–Early Triassic rifting.
Rome and the Vassal Kings: About some Aspects of Interrelationship
Authors: NIKISHIN V.O.
Published: March 2022

This article is devoted to the complicated relations between Rome and its client kingdoms from the II cent. BC up to the beginning of the II cent. AD. The author considers that the client kingdoms were not buffer states from the current viewpoint. In Strabo’s and other ancient authors’ consideration those kingdoms were the organic parts of the Roman Empire. Mutual relations between Rome and the client kings were created on the basis of traditional relationship of patronatus and clientela. The system of client kingdoms was formed during the rule of Augustus. The founder of Principate in the course of his internal and foreign policy leant on the vassal kings, many of whom during their youth lived, brought up and educated in Rome. The Roman henchmen who took their thrones in the neighboring states, as a rule, not for long kept the power in their hands: usually they were overthrown by the leaders of local elites. Those client kings, who ruled inside the frontiers of the Roman Empire, generally coped well with their responsibility: in peacetime they provided the rule of law in their kingdoms and in case of war supplied the Roman troops with everything necessary. Nevertheless, Augustus’ successors eliminated the most of client kingdoms, having replaced the principle of vassalage by the practice of direct control. That policy was being realized as part of a general trend towards strengthening of the imperial power. As a result by the beginning of the II cent. BC many client kings lost their thrones, and their kingdoms were turned into provinces of the Roman Empire.
