Hospital admissions through the National Health System (SUS) in the east of south expanded health region of Minas Gerais, Brazil, between 2014 and 2018
Hospitalizations occur electively in cases with no imminent risk to life or in cases of urgency and emergency, which demand immediate medical assistance. In a Health Region, these hospitalizations are conducted in reference hospitals. This study aimed to analyse hospital admissions in the Eastern South Region of Minas Gerais, by comparing the number of urgency and emergency admissions with elective procedures admissions and with the number of urgency admissions with sensitive to primary care conditions (CSAP). This longitudinal-retrospective-descriptive study was conducted with Hospital Information System (SIH) data relative to the 2014-2018 interval. Altogether, there were registered 129,524 hospitalizations, with 17,546 (13.55%) being elective admissions and 111,978 (86.45%) urgency procedures. Of the urgency hospitalizations total, 20,108 (17.95%) were CASP hospitalizations. The frequency of urgency hospitalization was six times higher than the elective hospitalization one, and even SPCC emergency admissions exceeded the elective hospitalizations offer
Application of a strain gauge to assess drying stresses in normal and tension wood of corymbia citriodora
The quantitative evaluation of longitudinal drying strain can provide relevant information for the processing wood and lumber industry, especially with regard to reaction wood in Corymbia, since little has been published. The objective of this work was to evaluate the effect of the steam conditioning and the cooling on the longitudinal drying strain (LDS) obtained from a strain gauge, called extensometer, in boards of both normal and tension wood of Corymbia citriodora. Lumbers 30 mm thick were produced and kiln dried at the initial temperature of 40 °C, final temperature of 65 °C and drying potential of 2,1. The LDS were measured before and after steam conditioning on hot and cold lumbers. It was observed that the conditioning did not reduce the LDS. Hot lumbers showed higher LDS values than the cold lumbers. The LDS values measured in normal, tension and opposite woods were statistically similar, indicating that the type of wood was not an influential factor in the appearance of longitudinal drying stresses. Extensometer proved to be feasible for measuring LDS, allowing its easy and quick quantification
POLÍTICA DE CONCESSÃO DE CRÉDITO RURAL: OS MECANISMOS DO AGROAMIGO DO NORDESTE
Brazil, due to its extensive territorial dimension, is considered a benchmark in agricultural production among developing countries. Within this context, agriculture plays a crucial role in the Brazilian economy as it contributes significantly to the balance of trade. Thus, the Brazilian agricultural production experience since year 2004, excellent prospects for sustainable growth and consistency, strong leadership in achieving the production of soybeans, corn, coffee, meat, sugar and others. Thus, since 1990 there are some institutions implementing microcredit programs. One of the most prominent is the Bank of Northeast of Brazil with Agroamigo. The present study describes how the methodology for granting credit - Agroamigo – to the farmers. The methodology used in this study was exploratory and descriptive. Research resources were books, articles, journals, reports, theses and dissertations, and especially official databases. The Agroamigo method had given positive results to communities in the municipality, as there was also a growth in rural activities, according to the BNB (2009), in the order of 40%. The program has enhanced access to rural credit for small farmers and provided improvements in their lives
De junho de 2013 às confederações democráticas dos brasis menores
Após análise do panorama geral da recente política brasileira, pretendeu-se no presente trabalho formular proposições políticas compatíveis com as potências democráticas que irromperam nas Jornadas de Junho de 2013. Objetivando escapar do atual cenário de polarizações entre a esquerda tradicional e o patriotismo autoritário, primeiramente examinamos os eventos de junho tendo como referencial teórico o conceito de “democracia radical” de Douglas Lummis, assim como os de “multidão” e “comum” de Michael Hardt e Antonio Negri. Verificou-se então que a horizontalidade e a cooperação foram características marcantes nos protestos de junho. A partir dessa verificação e de outros pressupostos, elaboramos um esboço de projeto político que denominamos “confederações democráticas dos brasis menores”, baseado nas ideias de autogoverno popular e na autogestão das atividades político-econômicas
Viticulture under climate change: A case study on a water scarcity model
Changes in climatic patterns hinder the prediction of water availability, being imperative to develop new strategies to optimise water management in the agricultural sector. A multi-sensor network is being developed by ADVID/CoLAB VINES&WINES and University of Trás-os-Montes and Alto Douro (UTAD), aiming to determine water stress in vineyards, as a Decision Support System (DSS) for winegrowers. Remote wireless data transmission through LoRaWAN technology, will allow the development of a Machine Learning based model for water stress mapping. Measured parameters include soil, plant, and atmosphere data, given the importance of soil-plant-atmosphere continnum when evaluating water status. The pilot is installed in a commercial vineyard in the Douro Demarcated Region (DDR), and different sensor’s modules were distributed spatially in the parcel. Lower cost and higher range than WiFi or Bluetooth, LoRaWAN are especially important for applications in remote areas, where mobile networks have little coverage, allowing to benefit a larger number of producers. While overcoming the constraints of the current monitoring method (Scholander pressure bomb), this system will allow remote and continuous water monitoring, assisting the producer in decision making. Altogether, this solution will contribute to better management of water resources, as well to the sustainability and competitiveness of farms
Changing the calculated surface area of wood samples to define drying schedules for Eucalyptus clones
The aim of this study was to determine how varying the inputted surface area value of wood samples would affect the determination of kiln-drying schedules using the drastic drying test. For this purpose, eight individuals of two Eucalyptus clones were selected. Specimens were obtained for drastic drying tests at 100 °C, to measure the basic density and to determine the initial moisture content. The initial and final temperatures and the drying potential were calculated in 100 mm × 50 mm × 10 mm samples, considering the surface area to be 130 cm² (Updated Method), in contrast to the surface area of 100 cm² that is commonly used in the method known as the Standard Method. Based on these findings, kiln-drying schedules were set for the lumber from each clone. Although the significant differences aforementioned, it was observed that the drying schedules developed by Standard Method and Updated Method are similar
Analysing the drying behavior of juvenile and mature Eucalyptus saligna wood in drastic drying test for optimal drying schedule
The heterogeneity of characteristics observed in the pith-bark direction within a log causes sawn pieces of wood have different behaviors during water removal. Understanding these differences is important for the industry regarding the possibility of classification of the lumber into juvenile wood and mature wood, facilitating the drying in separate loads. Thus, this study aimed to evaluate the behavior of juvenile and mature wood samples of Eucalyptus saligna when subjected to drastic drying. In order to do this, test specimens were submitted to drastic drying at 100°C to obtain the drying times, drying rates and dimensions of end checks. These data were applied in equations to obtain the parameters initial temperature, final temperature and drying potential, used in the elaboration of drying schedules. In juvenile wood we observed that the basic density was lower and the initial moisture content was higher. Mature wood showed a lower drying rate. Drying schedules were developed separately for juvenile and mature wood, the drying schedule for the latter considered milder than the drying schedule developed for juvenile wood
Germination of cotton cultivar seeds under water stress induced by polyethyleneglycol-6000
The physiological quality of cotton cultivar seeds (Gossypium hirsutum var. latifolium L.) was evaluated in laboratory by the simulation of water potentials with polyethyleneglycol-6000 (0.0; -0.2; -0.4; -0.6; -0.8 and -1.0 MPa), at 25ºC using germitest paper as substrate. A completely randomized design in a 4 × 6 factorial scheme with four replications of 50 seeds each was used. The studied variables were: germination percentage, first count of germination, germination velocity index, accelerated aging in water, electrical conductivity, humidity, vigor classification, radicle length and radicle/shoot length ratio. The effect of water stress on seed viability and on plantlet vigor was severe at potentials below -0.4 MPa. The 'CNPA 187 8H' cultivar was the least sensitive to the tested osmotic potentials, both in terms of germination and of vigor. The 'BRS-201' cultivar was mostly affected by the viability and vigor tests under water deficit conditions. Differential viability and vigor between cultivars were observed under the water stress levels.A qualidade fisiológica de sementes de cultivares de algodoeiro (Gossypium hirsutum var. latifolium L.) foi avaliada em laboratório pela simulação de potenciais hídricos com polietilenoglicol-6000 (0,0; -0,2; -0,4; -0,6; -0,8 e -1,0 MPa), na temperatura de 25ºC, em substrato papel germitest. O delineamento utilizado foi o inteiramente casualizado, em esquema fatorial 4 × 6, com quatro repetições de 50 sementes. As variáveis estudadas foram: porcentagem de germinação, primeira contagem da germinação e índice de velocidade de germinação, envelhecimento acelerado em água, condutividade elétrica, umidade, classificação de vigor (plântulas normais, fortes ou fracas), comprimento de radícula e relação radícula/parte aérea. O efeito do estresse hídrico na viabilidade das sementes e no vigor das plântulas foi severo a partir de -0.4 MPa. O cultivar CNPA 187 8H foi o menos sensível aos níveis de potenciais osmóticos testados tanto em termos de germinação, como de vigor. O cultivar BRS-201 foi o mais afetada nos testes de viabilidade e vigor em condições de déficit hídrico. Observou-se comportamento diferenciado em relação à viabilidade e vigor em diferentes níveis de estresse hídrico simulado por polietilenoglicol-6000
