METHODOLOGY FOR SYSTEMATICAL MAPPING OF ANNUAL CROPS IN MATO GROSSO DO SUL STATE (BRAZIL)

This paper presents the preliminary results of a methodology developed for the systematic mapping of annual crops, potentially applicable to the entire country. There are many interests and demands for information referring to agricultural activity worldwide. The execution of yearly crop harvests and its relation to the definition of future markets, the measurement of environmental impacts and, the formulation of public policies for agribusiness, are only some examples of the activities which would benefit from the data generation of cultures in the field. Mapping and monitoring the potential of daily images and of vegetation index from MODIS sensor system, in spite of its limitations due to the spatial resolution of 250m, has not yet been fully explored. The objective of this work is to develop and test a methodological approach based on the spectral/ temporal characteristics of an annual series of images from this sensor and to identify and map annual crops in the State Mato Grosso do Sul, produced with images of medium and high spatial resolution during the year 200

Interobserver agreement for the spine instability neoplastic score varies according to the experience of the evaluator

OBJECTIVES: To evaluate the interobserver agreement for the Neoplastic Spine Instability Score (SINS) among spine surgeons with or without experience in vertebral metastasis treatment and physicians in other specialties. METHODS: Case descriptions were produced based on the medical records of 40 patients with vertebral metastases. The descriptions were then published online. Physicians were invited to evaluate the descriptions by answering questions according to the Neoplastic Spine Instability Score (SINS). The agreement among physicians was calculated using the kappa coefficient. RESULTS: Seventeen physicians agreed to participate: three highly experienced spine surgeons, seven less-experienced spine surgeons, three surgeons of other specialties, and four general practitioners (n = 17). The agreement for the final SINS score among all participants was fair, and it varied according to the SINS component. The agreement was substantial for the spine location only. The agreement was higher among experienced surgeons. The agreement was nearly perfect for spinal location among the spine surgeons who were highly experienced in vertebral metastases. CONCLUSIONS: This study demonstrates that the experience of the evaluator has an impact on SINS scale classification. The interobserver agreement was only fair among physicians who were not spine surgeons and among spine surgeons who were not experienced in the treatment of vertebral metastases, which may limit the use of the SINS scale for the screening of unstable lesions by less-experienced evaluators

ESTUDOS DAS PLANTAS GLANDORA PROSTRATA E CUPHEA CARTHAGENENSIS

Glandora prostrata, típica da Europa e Cuphea carthagenensis típica de Santa Catarina, são plantas com aplicações na medicina popular e com alto poder farmacológico, desta forma, este trabalho visou realizar revisão bibliográfica e divulgações virtuais, com estudos de análises de extratos das plantas mencionadas. Com os dados coletados analisou-se que a planta Glandora prostrata e Cuphea carthagenensis apresentam aplicações farmacológicas e atividades antimicrobianas. As discussões e os seminários realizados nos encontros foram importantes para aprofundamento do assunto, e as postagens no Instagram contribuíram para levar a linguagem científica à comunidade local e regional, além de trazer esclarecimentos sobre as plantas

Dinâmica do uso das terras no Cerrado no período de 2002 a 2013

The objective of this work was to analyze land use dynamics in the Brazilian Cerrado region from 2002 to 2013. This analysis was based on the interpretation of Landsat satellite images carried out by the projects Projeto de Conservação e Utilização Sustentável da Diversidade Biológica Brasileira (Probio) and TerraClass Cerrado 2013, both coordinated by Ministério do Meio Ambiente. In 2002, 38.9% of the Cerrado was covered by some type of anthropic activity. In 2013, this percentage increased to 43.4%. One of the main highlights is the emergence of a new agricultural frontier in the northern region of the study area, known as Matopiba.O objetivo deste trabalho foi analisar a dinâmica de uso das terras na região do Cerrado de 2002 a 2013.

Um dos grandes destaques é o surgimento de uma nova fronteira agrícola na região norte da área de estudo, conhecida como Matopiba

A social and ecological assessment of tropical land uses at multiple scales: the Sustainable Amazon Network

Science has a critical role to play in guiding more sustainable development trajectories. Here, we present the Sustainable Amazon Network (Rede Amazonia Sustentavel, RAS): a multidisciplinary research initiative involving more than 30 partner organizations working to assess both social and ecological dimensions of land-use sustainability in eastern Brazilian Amazonia. The research approach adopted by RAS offers three advantages for addressing land-use sustainability problems: (i) the collection of synchronized and co-located ecological and socioeconomic data across broad gradients of past and present human use; (ii) a nested sampling design to aid comparison of ecological and socioeconomic conditions associated with different land uses across local, landscape and regional scales; and (iii) a strong engagement with a wide variety of actors and non-research institutions. Here, we elaborate on these key features, and identify the ways in which RAS can help in highlighting those problems in most urgent need of attention, and in guiding improvements in land-use sustainability in Amazonia and elsewhere in the tropics. We also discuss some of the practical lessons, limitations and realities faced during the development of the RAS initiative so far.Keywords: Social–ecological systems, Tropical forests, Land use, Interdisciplinary research, Sustainability, Trade-off

Dinâmica das queimadas no Estado do Mato Grosso e suas relações com as atividades antrópicas e a economia local.

A tese procura identificar e mapear a dinâmica de queimadas no Estado do Mato Grosso e explicar suas principais condicionantes, baseando-se em análises espaciais e estatísticas, desenvolvidas com os dados de queimadas e de variáveis ambientais, econômicas e sociais.Orientação: Prof. Dr. José Eli da Veig
