Análise morfométrica da bacia hidrográfica do Rio Doce, Goiás, Brasil

The watershed is very important to draw up a plan of the environment that are the major social and natural factors. This course conclusion work aimed to carry out a morphometric analysis of the Doce River watershed. The methodology used was indexes intended for this purpose. It consists of several units where all the hydrological procedures that distinguish the total water cycle. In this sense, the physical qualities of the basins must modulate the amplitude of these hydrological processes and cases that cause damage, as well as floods, and define the entire water availability of the large basin. The Doce River hydrographic basin presents degradation and cases of floods, and many water resources. Thus, a morphometric analysis of the fundamental sub-basins of the Rio Doce was carried out. It concludes with the main part of the hydrographic characterization of the Doce River basin, showing its importance.La cuenca hidrográfica es muy importante para trazar un plano del entorno donde están los grandes factores sociales y naturales.

Schematic models of wood for optic mineralogy and geosciences teaching / Modelos esquemáticos em madeira para o ensino de mineralogia óptica e de geociências

Optical physics applied to mineralogy becomes a complex concept, since it is based on concepts of refractoriness of isotropic and anisotropic materials, dependent on crystallographic parameters. The work aims to materialize these concepts in three-dimensional schematic models in wood, such as optical indicatrix and figures of interferences, generated when the plane polarized or polarized light interacts with several transparent minerals. The pieces were applied in the classes of Mineralogy II of the Geology course of the Federal University of Espírito Santo in the years 2017 and 2018, presenting great receptivity by the dissenting body and ease in the profusion of the knowledge of the group of monitors and teachers. The geometric representations were also shown in workshops at the Natural History Museum of Southern Espírito Santo State with the objective of disseminating the geosciences. As a result, the classes obtained satisfactory results of approval and learni

Thermal comfort and productive responses of 7/8 holstein-gyr cows subjected to cooling system

The objective of this research was to identify the influence of the evaporative adiabatic cooling system (EACS) on the thermal comfort and productive responses of dairy cattle, through multivariate analysis by principal components (PC), in the summer and winter seasons of the semiarid region of Pernambuco, Brazil. The data came from an experiment that included 16 multiparous lactating cows (7/8 Holstein-Gyr), randomly distributed in 4 sets, with 4 experimental phases and 4 treatments (0, 10, 20, and 30 min.). The multivariate analysis was carried out through PC for the thermal comfort indices, physiological variables, and milk production and composition. The highest milk production in the summer season was obtained for animals exposed to the cooling system for 30 min. In the winter season in the morning period, the use of the EACS for 10 min. was sufficient for improvements in milk production. The times of exposure to EACS caused changes in the composition of milk, for both seasons. Principal component analysis made it possible to verify a positive correlation of evaporative cooling with thermal comfort, physiological responses, and production and composition of milk of lactating cows

Carcinoma tubulopapilar em gata: Relato de caso

Tumores de mama em gatas correspondem ao terceiro lugar na casuística dos tumores diagnosticados nesta espécie. Cerca de metade dos tumores mamários de cães são malignos, já em felinos, as chances chegam a 90%, o que torna imprescindível um exame detalhado da cadeia mamária, principalmente em casos de animais submetidos a mastectomia simples, com histórico pretérito de tumoração. O estudo terá como objetivo analisar os aspectos clínicos e anatomopatológicos em um caso de carcinoma tubulopapilar em uma gata, sem raça definida, 9 anos de idade, de pelagem cor branca, castrada. O animal deu entrada no Hospital Veterinário, no município de Bayeux, Paraíba, com histórico de nodulação em mama abdominal esquerda e aumento de volume circunscrito de aspecto cístico no subcutâneo em região vizinha. A punção do cisto subcutâneo revelou grande volume de líquido com aspecto viscoso, de coloração amarelo-claro, o qual foi centrifugado e preparado em lâminas coradas com panótico rápido para a análise citológica. O estudo anatomopatológico propõe construir informações da histogênese desse tumor assim como a sua morfologia e desse modo contribuir para a clínica oncológica de felinos no que se refere ao estadiamento dos tumores e o aumento da sobrevida do paciente

Estudo da formação de aderências e da cicatrização de anastomoses colônicas em ratos com sepse peritoneal induzida

OBJETIVO: Avaliar os efeitos da sepse abdominal sobre a formação de aderências e a cicatrização de anastomoses colônicas em ratos. MÉTODOS: 40 ratos distribuídos em dois grupos contendo 20 animais, para anastomose do cólon esquerdo na presença (grupo S) ou ausência (grupo N) de indução de sepse por ligadura e punção do ceco (CLP). Cada grupo foi dividido em subgrupos para eutanásia no terceiro (N3 e S3) ou sétimo (N7 e S7) dia de pós-operatório (DPO). Foi avaliada a quantidade de aderências e removido um segmento colônico contendo a anastomose para análise histopatológica, força de ruptura, hidroxiprolina e conteúdo de colágeno tecidual. RESULTADOS: Os animais submetidos à CLP apresentaram maior quantidade de aderências intra-abdominais tanto no 3° DPO (p=0,00) quanto no 7° DPO (p=0,00). Tiveram menores valores de força de ruptura no 3° DPO (p=0,00), porém maiores valores no 7° DPO (p=0,00). Não houve diferença na variação da concentração de hidroxiprolina, conteúdo de colágeno e histopatologia. CONCLUSÕES: A infecção peritoneal desencadeada por CLP aumentou a quantidade de aderências intra-cavitárias. Houve diminuição da resistência de anastomoses cólicas no 3° DPO, com posterior aumento no 7° DPO, sem efeito sobre os outros parâmetros da cicatrização. ________________________________________________________________________________ ABSTRACTPURPOSE: To evaluate the effects of abdominal sepsis on adhesion formation and colon anastomosis healing in rats. METHODS: Forty rats were distributed in two groups containing 20 rats each for left colon anastomosis in the presence (Group S) or absence (Group N) of induced sepsis by cecal ligation and puncture. Each group was divided into subgroups for euthanasia on the third (N3 and S3) or seventh (N7 or S7) post-operative day. The amount of adhesions was evaluated and a segment of the colon was removed for histopathologic analysis, bursting strength assessment, hydroxyproline and the determination of tissue collagen. RESULTS: The subjects which underwent cecal ligation and puncture presented a higher amount of intra-abdominal adherences in both third (p=0,00) and seventh (p=0,00) post-operatory days. Smaller bursting strengths were found in the S3 subgroup, and greater bursting strengths were found in the S7 subgroup. There was no difference in the variations on the concentrations of hydroxyproline, tissue collagen and histopathology. CONCLUSIONS: The peritoneal infection which was developed by cecal ligation and puncture raised the amount of intra-cavitary adhesions. There was a decrease in the amount of colonic anastomosis on the third post-operatory day with a following raise on the seventh without any effects on other healing parameters

Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders guidelines for the treatment of adult obsessive-compulsive disorder. Part II: cognitive-behavioral therapy

Objectives: To summarize evidence-based cognitive-behavioral therapy (CBT) treatment and propose clinical interventions for adult patients with obsessive-compulsive disorder (OCD). Methods: The literature on CBT interventions for adult OCD, including BT and exposure and response prevention, was systematically reviewed to develop updated clinical guidelines for clinicians, providing comprehensive details about the necessary procedures for the CBT protocol. We searched the literature from 2013-2020 in five databases (PubMed, Cochrane, Embase, PsycINFO, and Lilacs) regarding study design, primary outcome measures, publication type, and language. Selected articles were assessed for quality with validated tools. Treatment recommendations were classified according to levels of evidence developed by the American College of Cardiology and the American Heart Association. Results: We examined 44 new studies used to update the 2013 American Psychiatric Association guidelines. High-quality evidence supports CBT with exposure and response prevention techniques as a first-line treatment for OCD. Protocols for Internet-delivered CBT have also proven efficacious for adults with OCD. Conclusion: High-quality scientific evidence supports the use of CBT with exposure and response prevention to treat adults with OCD
