The objective of this study was to analyze changes in the spectral behavior of the soybean crop through spectral profiles of the vegetation indexes NDVI and GVI, expressed by different physical values such as apparent bi-directional reflectance factor (BRF), surface BRF, and normalized BRF derived from images of the Landsat 5/TM. A soybean area located in Cascavel, Paraná, was monitored by using five images of Landsat 5/TM during the 2004/2005 harvesting season. The images were submitted to radiometric transformation, atmospheric correction and normalization, determining physical values of apparent BRF, surface BRF and normalized BRF. NDVI and GVI images were generated in order to distinguish the soybean biomass spectral response. The treatments showed different results for apparent, surface and normalized BRF. Through the profiles of average NDVI and GVI, it was possible to monitor the entire soybean cycle, characterizing its development. It was also observed that the data from normalized BRF negatively affected the spectral curve of soybean crop, mainly, during the phase of vegetative growth, in the 12-9-2004 image.

The main objective of this work was to evaluate the linear regression between spectral response and soybean yield in regional scale. In this study were monitored 36 municipalities from the west region of the states of Parana using five images of Landsat 5/TM during 2004/05 season. The spectral response was converted in physical values, apparent and surface reflectances, by radiometric transformation and atmospheric corrections and both used to calculate NDVI and GVI vegetation indices. Those ones were compared by multiple and simple regression with government official yield values (IBGE). Diagnostic processing method to identify influents values or collinearity was applied to the data too. The results showed that the mean surface reflectance value from all images was more correlated with yield than individual dates. Further, the multiple regressions using all dates and both vegetation indices gave better results than simple regression.

A new species of Mimosa (Leguminosae, Mimosoideae, Mimosae) from Mato Grosso do Sul state, Midwestern Brazil, M. ferricola R.R. Silva & A.M.G. Azevedo, is described and illustrated. Morphologically M. ferricola is related to M. gemmulata Barneby and to M. nothopteris Barneby, and belongs to Mimosa sect. Batocaulon DC. ser. Leiocarpae Benth.

Mother and infant mortality has been the scope of analysis throughout the history of public health in Brazil and various strategies to tackle the issue have been proposed to date. The Ministry of Health has been working on this and the Rede Cegonha strategy is the most recent policy in this context. Given the principle of comprehensive health care and the structure of the Unified Health System in care networks, it is necessary to ensure the integration of health care practices, among which are the sanitary surveillance actions (SSA). Considering that the integration of health care practices and SSA can contribute to reduce mother and infant mortality rates, this article is a result of qualitative research that analyzed the integration of these actions in four cities in the State of São Paulo/Brazil: Campinas, Indaiatuba, Jaguariúna and Santa Bárbara D'Oeste. The research was conducted through interviews with SSA and maternal health managers, and the data were evaluated using thematic analysis. The results converge with other studies, identifying the isolation of health care practices and SSA. The insertion of SSA in collectively-managed areas appears to be a potential strategy for health planning and implementation of actions in the context under scrutiny.

The objective of this work was to compare the soybean crop mapping in the western of Parana State by MODIS/Terra and TM/Landsat 5 images. Firstly, it was generated a soybean crop mask using six TM images covering the crop season, which was used as a reference. The images were submitted to Parallelepiped and Maximum Likelihood digital classification algorithms, followed by visual inspection. Four MODIS images, covering the vegetative peak, were classified using the Parallelepiped method. The quality assessment of MODIS and TM classification was carried out through an Error Matrix, considering 100 sample points between soybean or not soybean, randomly allocated in each of the eight municipalities within the study area. The results showed that both the Overall Classification (OC) and the Kappa Index (KI) have produced values ranging from 0.55 to 0.80, considered good to very good performances, either in TM or MODIS images. When OC and KI, from both sensors were compared, it wasn't found no statistical difference between them. The soybean mapping, using MODIS, has produced 70% of reliance in terms of users. The main conclusion is that the mapping of soybean by MODIS is feasible, with the advantage to have better temporal resolution than Landsat, and to be available on the internet, free of charge.

A revision of the Brazilian species of Lonchocarpus s. str. is presented. This study is based on field observation and an analysis of approximately 1,200 herbarium collections. Nine species are recognized, L. cultratus, L. hedyosmus, L. latifolius, L. macrocarpus, L. nitidus, L. pluvialis, L. sericeus, L. spiciflorus, and L. violaceus, which grow in forests and are usually associated with river banks. Lonchocarpus sericeus and L. cultratus have a wide distribution throughout Brazil, whereas L. hedyosmus, L. macrocarpus, L. spiciflorus, and L. latifolius are restricted to the Amazonian domain. Lonchocarpus pluvialis occurs in the Central-West (Mato Grosso do Sul and Goiás) and Southeast (São Paulo) regions. Lonchocarpus violaceus is found in the states of Bahia and Espírito Santo, and is reported for the first time for Brazil. Identification keys, descriptions, and illustrations, in addition to information about habitat, geographic distribution and taxonomic and nomenclatural comments, are provided for the species. Four new synonyms and five lectotypifications are proposed.

Purpose: To identify improvement in visual performance of low vision students after assessment and management conducted at the Low Vision Service of State University of Campinas (UNICAMP). Method: Fourteen low vision students aged six to 30 years, attended in a room with resources for visual deficiency in Americana and Santa Bárbara d'Oeste -- SP during 1998 received complete ophthalmologic examination, specialized low vision assessment and educational intervention. Results: The most prevalent cause of vision loss was operated congenital cataract with four cases (28.6%), followed by congenital bilateral toxoplasmic macular scars and eye malformation, both with two cases (14.3%) cases each. Eight students (57.2%) had acuity classified as severe vision loss, four (28.6%) profound, one (7.1%) moderate and one (7.1%) nearly normal vision. Twelve (85.7%) were behind expected school grade. Optical aids were prescribed for 12 (85.8%) students but only 7 (58.3%) acquired the aids thus improving significantly their school performance. Conclusion: All students improved school performance even considering that 12 (85.7%) had severe to profound vision loss. As a group their performance could even be better if the optical aid prescriptions were acquired by all. This indicates the need of a social work to support such needs. For good results at school and effective student inclusion a partnership between school, family and specialized education is necessary. We recommend to promote the benefits of the resource room.
