<p>A água é um dos recursos naturais mais preciosos e é indispensável à manutenção da vida. Conhecer a quantidade e a qualidade dos recursos hídricos do país é pressuposto para definição de estratégias que busquem a sua conservação, recuperação e o seu uso racional é meta imprescindível para toda a sociedade. Sabe-se que a<strong> </strong>ocupação e o uso do solo alteram os processos físicos, químicos e biológicos dos recursos hídricos. Não obstante ser o país mais bem aquinhoado em termos percentuais de água doce, sua distribuição geográfica é bastante irregular no Brasil. Regiões como o semiárido nordestino e o Vale do Jequitinhonha mineiro, historicamente enfrentam problemas relacionados à falta d’água. Nos últimos anos essa situação tem piorado, em termos de quantidade e qualidade. Assim, a proposta deste trabalho consiste na avaliação da qualidade das águas superficiais da sub-bacia do rio Capivari no município de Chapada do Norte, Alto Jequitinhonha, nordeste de Minas Gerais. Foi utilizado como técnica de análise o Índice de Qualidade da Água – IQA, utilizado pelos principais órgãos de gestão das águas do país, como a CETESB/SP e o IGAM/MG.</p><p> </p><p><strong>Palavras-Chave: </strong>Sub-bacia do rio Capivari; Chapada do Norte; IQA.</p><p> </p><p><strong>Abstract</strong></p><p>Water is one of the most precious natural resources and is indispensable to the maintenance of life.

ABSTRACT The 'Ubá' mango tree cultivar is very important for the juice industry in the "Zona da Mata" region of the Minas Gerais State, in Brazil, but problems such as uneven flowering and low yield have discouraged producers. This study aimed at evaluating the effect of paclobutrazol, combined with branch tip pruning, on the flowering induction and quality of 'Ubá' mango tree fruits. Treatments were distributed in a 5 x 2 + 1 factorial arrangement, consisting of five paclobutrazol doses (0 g, 0.50 g, 1.00 g, 1.50 g and 2.0 g per linear meter of canopy), with and without branch tip pruning, in a randomized blocks design, with four replicates. The flowering percentage, number of panicles per branch, total flowers per panicle, male/hermaphrodite flowers ratio, number of fruits per branch and fruit quality were evaluated. Plants treated with tip pruning showed a higher flowering percentage. There was an increase in the flowering percentage in response to the paclobutrazol dose, reaching a maximum level at the dose of 1.62 g per linear meter of canopy. Plants submitted to branch tip pruning had a higher number of panicles per branch. There was an increase in the male/hermaphrodite flowers ratio with increasing paclobutrazol doses. Branch tip pruning increased the number of fruits per branch. There were no differences in fruit quality in response to the paclobutrazol application. It was concluded that the paclobutrazol application at the dose of 1.62 g per linear meter of canopy, combined with branch tip pruning, increases the flowering of the 'Ubá' mango tree and does not change the fruit quality.

<p>O estudo foi realizado no município de Rio Acima, localizado ao sul da região metropolitana de Belo Horizonte - MG. Na primeira etapa, foi feita a determinação das áreas de preservação permanente (APPs) do município, segundo a Lei 12.651 e a resolução CONAMA 303/2002 (esta última para delimitar as APPs de topo de morro), utilizando cinco bases topográficas distintas: vetorização de cartas do IBGE na escala de 1:50.000, imagem SRTM, Topodata, ASTER V2 e uma base vetorial disponibilizada pelo Codemig com curvas de nível equidistantes em 10 metros. Na segunda etapa, foram calculadas as áreas de cada uma das classes de APP resultantes dos mapeamentos feitos a partir de todas as bases e, em seguida, estes valores foram comparados. Ao final, foi observado que os resultados obtidos a partir da base do IBGE e da imagem ASTER V2 são os que apresentam característica mais restritiva, ou seja, com maiores áreas de preservação. Por outro lado, o mapa de áreas de preservação permanente confeccionado a partir da imagem SRTM foi o que apresentou caráter menos restritivo. Neste estudo também são discutidas outras diferenças entre os mapas elaborados a partir das cinco bases. </p><p> </p><p><strong>Palavras–chave:</strong> Município de Rio Acima, áreas de preservação permanente, modelos digitais de elevação, resolução espacial.</p><p><strong> </strong></p><p><strong> </strong></p><p><strong>Abstract </strong></p><p>This study was conducted in the municipality of Rio Acima (Minas Gerais State) located in the southern Belo Horizonte metropolitan region.

These bases are the following: the vector at a 1:50.000 scale provided by the Brazilian Institute of Geography and Statistics (IBGE), SRTM image, image provided by INPE Topodata project, ASTER V2 Image and a vector base released by Codemig with 10 meters contour distance. In the second stage the areas of each one PPA classes were calculated resulting from all mapping bases. Then these values were compared. Finally it was observed that the results obtained from the ASTER V2 image and IBGE base are those with more restrictive features or in other words the result with lager PPAs. Moreover, the map of permanent preservation areas made from SRTM image showed the least restrictive character. This study also discusses other differences between the maps drawn from the five bases.</p><p><strong> </strong></p><p><strong>Keywords</strong>: Rio Acima municipality, permanent preservation areas, digital elevation models,   spacial resolution.</p>

In the Caborca area, water scarcity is the main problem for the farmers, because of the depletion of the aquifer. This is the main reason why they are focusing on orchards and vegetables. Melon is the vegetable annual crop more extensively grown in this area and is furrow-irrigated with 120 cm of water. But, because of the scarcity of water, it is necessary to use drip irrigation. The objective of this study was to validate in a commercial field (15 ha) the effects of drip irrigation system on the water use, yield, and quality of two honeydew melon varieties (green flesh and orange flesh) in the Caborca area. Our results indicate that, with 50 cm of water applied, yields were 2146 to 2802 boxes/ha for green flesh and orange flesh, respectively. The predominant sizes were 4s and 5s with 25% and 38% for green flesh, and 5s and 6s with 42% and 36% for orange flesh. These sizes are the best for the exportation market.

The Dr. Salatiel Square, located at Marechal Bittencourt Street in the historical center of the São João del-Rei city, Minas Gerais State, Brazil, appeared in the twentieth century during the period of hygienism. It was inserted in a place that over the years suffered several modifications on its morphology. The work aims to study the landscape aspects and socio-cultural evolution of this square. This work execution consisted of the two steps: field research for the identification of the historical square significance, and a research that was carried out in the historical collections of the city. During the field research, it was collected the current state of Dr. Salatiel Square as well as its uses and potentials, and its botanical composition. Analyzing the square and its surroundings, and also the information collected in São João del-Rei, Minas Gerais State, Brazil, it was possible to verify that the site, which nowadays the Dr. Salatiel Square is placed, was occupied before by European influenced houses that were overthrown later in the period of hygienism. Among all the nomenclatures already attributed to the street that shelter the square, the best known by population is Cachaça’s Street due to the commerce of the time which favored the nightlife and bohemia. The square in study is part of the historical center of the city, and all its surroundings are overturned. However, the square has faced significant constructive and botanical modifications on its structure constituting a space characterized by the abandonment due to factors such as accumulation of garbage and great flow of vehicles. From the carried out study, it was verified that the number of information about the place is scarce, so that the continuation of its historical rescue is of great importance for means of preserving the history of the city and the population.

This study aims to evaluate changes in quality of life of cancer patients at the beginning of the first and the second cycle of chemotherapy (CT) in hospitals in Belo Horizonte, Minas Gerais State, Brazil. Longitudinal, prospective, descriptive study with a quantitative approach. We enrolled 230 patients, from a broader cohort, diagnosed with the five most frequent types of cancer (breast, colorectal, cervical, lung, and head and neck), aged 18 years or older, who were initiating CT for the first time. quality of life was assessed with the EORTC QLQ-C30 version 3, applied at the beginning of the first and second chemotherapy cycle. The paired Wilcoxon test was used to identify differences in quality of life between the two time points. A multivariate linear regression analysis was performed using the bootstrap method to investigate potential predictors of global health Status/quality of life. There was a significant increase in patients’ emotional function scores (p < 0.001) as well as symptom scores for pain (p = 0.026), diarrhea (p = 0.018), and nausea/vomiting (p < 0.001) after initiation of CT. Widowhood was associated with improvements in the global health Status/quality of life (p = 0.028), whereas the presence of cervical cancer (p = 0.034) and being underweight (p = 0.033) were related to poorer global health status/quality of life scores. CT has detrimental effects on patients’ physical health but, on the other hand, it leads to improvements in the emotional domain. Patients’ individual characteristics at the beginning of CT are associated with changes in their quality of life. Our study could help identify these characteristics.
