This work evaluated the quality of the fruit in peach and nectarine cultivars with and without the application of hydrogenated cyanamide and mineral oil, for two production cycles (2009 and 2010). The experiment was carried out at the School of Agricultural Science of the São Paulo State University (UNESP), at Botucatu in the Brazilian state of São Paulo, located at latitude 22º51'55 S and longitude 48º26'22 E, at an altitude of 810 m. The predominant climate type is warm temperate (mesothermal) with rains in the summer and dry in the winter. The following were evaluated: soluble solids, titratable acidity, pH, ratio, firmness, vitamin C and pulp yield. The use of hydrogenated cyanamide and mineral oil had no effect on the quality attributes of the fruit, except for pH, where those fruits under application of the products showed higher values. The cultivars all had a pulp yield greater than 90%, with 'Tourmaline' showing the highest yield (96 %). The levels of vitamin C varied according to the cultivars, where 'Marli' (16.9 mg 100 g-1) and 'Dourado-2' (16.5 mg 100 g-1), stood out for having the highest levels.

O Estado de São Paulo apresenta poucos remanescentes de vegetação nativa, ameaçados pela expansão urbana e agricultura. Com a grande expansão das atividades silviculturais no país, estudos sobre as contribuições e impactos das florestas plantadas são de grande importância na análise da sucessão secundária e conservação de ambientes naturais. O trabalho teve como objetivo a análise da composição florística e estrutura fitossiológica do estrato arbustivoarbóreo de uma comunidade vegetal regenerante na face norte dos talhões 91G, 91H e 91I, na Floresta Estadual “Edmundo Navarro de Andrade” (FEENA), em Rio Claro, SP, em uma área anteriormente ocupada por Eucalyptus sp, sendo as espécies classificadas quanto as classes sucessionais e síndromes de dispersão. A área correspondente aos talhões 91G, 91H e 91I está incluída no Plano de Manejo como Zona de Recuperação, para posterior inclusão no zoneamento como área permanente. Foram alocadas 28 parcelas com dimensões de 20x10 metros cada, totalizando 0,56 ha amostrados. Os resultados indicaram a presença de 79 espécies pertencentes a 34 famílias, sendo as famílias Fabaceae, Asteraceae, Euphorbiaceae e Myrtaceae as mais representativas em número de espécies. Houve grande abundância e dominância de Virola sebifera e Siparuna guianensis, amplamente distribuídas na área. A maior parte das espécies amostradas é pioneira ou secundária inicial, sendo a grande maioria zoocórica, o que sugere presença de fauna. Foram encontradas muitas espécies generalistas, algumas típicas de floresta e cerrado, portanto, a área assemelha-se a um ecótono de cerrado e floresta estacional semidecidual, com maior abundância e biomassa de espécies generalistas e típicas de cerrado. Dessa forma, a riqueza encontrada foi considerada alta em comparação com outros estudos realizados na FEENA, sendo indicada... (Resumo completo, clicar acesso eletrônico abaixo)

In the last few decades, Brazil has experienced an accelerated urbanization process in which many cities have grown in a disorderly way occupying environmentally fragile areas unsuitable for habitation. Anthropogenic actions such as high levels of impermeable soil, structural changes in watercourses, lack of riparian vegetation, illegal presence of trash and rubbish along the river banks added to irregular settlements in floodplains result in the rise of high risk areas. When accompanied by intense and prolonged rainfall phenomena, those areas have been the scenery of serious accidents such as floods. This study aims to classify the level of the risk of floods in the neighborhood of Jardim Inocoop, in the town of Rio Claro, São Paulo countryside, Brazil. One of the main technical support to tackle this issue is the identification and classification of the risks. In order to classify the risk level of flood in this case study, the methodology adopted was developed by the Ministry of Cities and Technology Research Institute, and take into account the arrangement of the hydrological scenario, vulnerability of households and dangerous process according to the distance of the houses from the axis of drainage. Therefore, the risk levels adopted to classify are listed below: very high (MA), high risk (A), moderate (M) and low risk (B). In conclusion, it is imperative to develop prevention plans in order to avoid or to minimize the damages caused by natural disasters. Therefore, the zoning of the risk sceneries remains as an important issue once it helps to identify the areas with high level risk of flood. Consequently, the occupation must be regulated where there is low or absent risk and it must be often forbidden where the high risk of flood is detected. Thus, the present study remains as an attempt to notify the risk of floods through its spatialization on a map, remainig...(Complete abstract click electronic access below)

The disaster natural disaster stand as one of the greatest challenges of urban man. Cities are built and modeled as a function of economic and political issues, without respecting environmental characteristics. So it is possible to see through the data of the National Civil Defence large number of disasters occurring in Brazilian cities in the years 2009 to 2011, and in all were reported over 5000 occurrences of natural disasters over the years. The Brazilian public policy failures show up in issues of urban planning where to admit the allocation of people in inappropriate areas. Another issue to be considered is the non-response of the population to civil defense warnings, people often prefer to risk staying in high-risk areas for fear of being robbed while they are away, and end up not serving the notices given by the Civil Defense, increase thus the number of victims when in fact the weather event triggers natural disasters one
