ELDERLY LIFE QUALITY DOMCILIED IN CARPINA (PERNAMBUCO STATE, BRAZIL) DETERMINED BY BARTHEL INDEX

The objective of this study was to determine the quality of life in elderly Health Family Units (HFU) in Carpina (PE, Brazil) evaluated by Barthel Index and application of geostatistical tools. The main conclusions are the Barthel Index characterized the elderly of municipality as independent, with scattered cases of dependency in the elderly, being directly related frameworks of advanced age; the sampling scheme was not sufficient to detect the spatial variability of the data.

Remoção de sólidos suspensos e totais em biofiltros operando com esgoto doméstico primário para reuso na agricultura

Removal of suspended and total solids in biofilters operating with primary domestic sewage for reuse in agriculture This study aimed to evaluate the removal of suspended and total solids in biofilters filled with composted waste, sugar cane bagasse and sawdust submitted to the application rates of domestic sewage of 0.5, 1.0 and 1.5 m 3 m -2 d -1 in Vicosa-MG. An experimental test unit was set up in experimental area of the Federal University of Vicosa. The concentrations of suspended and total solids were determined monthly during a period of 153 days. The experiment was arranged in a split split plot design, with the application rates of domestic sewage in the plots, the types of organic material in the splitplots and evaluation period in the split-splitplots, in a completely randomized design with three replications. The results indicated that the biofilter provided removal of suspended and total solids up to 82 and 46%

SPECTRAL INDICES OF VEGETATION TO CAATINGA OF THE AREA OF SEMI-ARID OF RIO GRANDE OF NORTE, BRAZIL *

The Caatinga is an exclusively Brazilian vegetation, predominantly in the Northeast, which covers 10% of the country, being an environment understudied, especially in view of remote sensing. Thus, the aim of this study is to analyze the spatial and temporal changes in vegetation of Caatinga, in the period from 2008 to 2011, through products and techniques of remote sensing data from the Landsat 5 TM, combined with weather data. The study was conducted in the area of the proposed National Park of Furna Feia located in the municipalities of Mossoró and Baraúna in the state of Rio Grande of Norte, situated in the semiarid region of northeastern Brazil. We used three images from Landsat 5 TM satellite orbit point 63 and 216 on the following dates: 13 August 2008, 01 September 2009 and 06 August 2011. The image processing for calculating the Normalized Difference Vegetation Index values (NDVI) was performed with ERDAS Imagine 9.1 and ArcGIS 9.3. The junction of products from remote sensing with weather data allowed a coherent and reasoned, where they subsidize an understanding of physical phenomena relating to rainfall variability of the response timeline of Caatinga vegetation. There was an increase in NDVI values over the years studied, noting the direct relationship with the occurrence of rainfall.
