REGIONALIZAÇÃO E ESPACIALIZAÇÃO DE VAZÕES DE PERMANENCIA: ESTUDO APLICADO NA BACIA RIO PIRACICABA-MG

Visando suprir a escassez de informações fluviométricas associada à inconsistência temporal e espacial das séries históricas disponíveis, a regionalização de vazões surge como uma alternativa para explorar mehor os dados já existentes. Dentre os diversos métodos existentes, um dos mais difundidos é o Método Tradicional (MT), o qual consiste na identificação de regiões hidrologicamente homogêneas e no ajuste de equações de regressão entre as diferentes variáveis selecionadas a serem regionalizadas. Nesse sentido, o objetivo deste trabalho é regionalizar as vazões com permanência de 95% do tempo (Q95) obtida pelo MT na bacia do rio Piracicaba-MG. Para tanto, foram utilizadas as estações fluviométricas disponíveis pela ANA, considerando apenas aquelas que apresentaram mais de cinco anos de dados com tolerância de 10%. A escolha do melhor método foi determinada pela análise do erro relativo e pelo Coeficiente de Eficiência de Nash e Sutcliffe. Como resultados, pode-se inferir que o modelo potencial apresentou excelentes resultados, com erros menores do que em relação aos outros modelos. Consideradas as dificuldades enfrentadas, concluiu-se que a metodologia testada apresentou resultado satisfatório, embora esse método substitui uma densa rede hidrometeorológica

Diagnosis, Prognosis and Treatment of Canine Cutaneous and Subcutaneous Mast Cell Tumors

Mast cell tumors (MCTs) are hematopoietic neoplasms composed of mast cells. It is highly common in dogs and is extremely important in the veterinary oncology field. It represents the third most common tumor subtype, and is the most common malignant skin tumor in dogs, corresponding to 11% of skin cancer cases. The objective of this critical review was to present the report of the 2nd Consensus meeting on the Diagnosis, Prognosis, and Treatment of Canine Cutaneous and Subcutaneous Mast Cell Tumors, which was organized by the Brazilian Association of Veterinary Oncology (ABROVET) in August 2021. The most recent information on cutaneous and subcutaneous mast cell tumors in dogs is presented and discussed

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

O que é o urbano, no mundo contemporâneo

Contemporary life central concepts such as politics, civilization and citizenship, derive from the city form and organization. A city conveys labor socio-spatial division, thus Henri Lefebvreproposes to think its transformation on the basis of a continuum that extends from the political city to the urban environment, when and where it completes its countryside domination. The city’s transformation into urban environmentwas marked by an industrial takeover that brought power to production and to working class. The city, as the surplus, power and fiesta locus, as well as a privileged scenario of socialreproduction, was thus subordinated to the industrial logics. The city thus experienced a double process: its centrality imploded upon itself and its outskirts exploded upon the surrounding areas through the urban tissue, which carries within it the polis and civitas germ. Therefore, the urban praxis, formerlyrestricted to the city, has now re-politicized the social space as a whole. In Brazil, urban environment had its origin in the military government concentrating and integrating politics that followed Vargas’s centralization and expansionism, and Kubitschek’s developmental interiorizing. Today, the urbanindustrial process virtually imposes itself on all social space through the extended urbanization of our daysConceitos centrais da vida contemporânea, tais como política, civilização e cidadania, derivam da forma e organização da cidade.A cidade expressa a divisão socioespacial do trabalho, e Henri Lefebvre propõe pensar sua transformação a partir de um continuum que se estende da cidade política ao urbano, ondese completa a dominação sobre o campo. A efetiva passagem da cidade ao urbano foi marcada pela tomada da cidade pelaindústria, trazendo a produção e o proletariado para o espaço do poder. A cidade, lócus do excedente, do poder e dafesta, cenário privilegiado da reprodução social, ficou, assim, subordinada à lógica da indústria. Sofreu, então, um duplo processo: sua centralidade implodiu sobre si mesma esua periferia explodiu sobre o entorno sob a forma de tecido urbano, que acabou por carregar consigo o germe da pólis e da civitas. Assim, a práxis urbana, antes restrita à cidade, re-politizou todo o espaço social. No Brasil, o urbano teve sua origem na política ao mesmo tempo concentradora e integradora dos governos militares, que deram seqüênciaà centralização e expansionismo varguista e à interiorização desenvolvimentista juscelinista. Hoje, o urbano-industrial impõe-se virtualmente a todo o espaço social, naurbanização extensiva dos nossos dias
