13. Texture analysis of masses in digitized mammograms using Gleason and Menhinick diversity indexes
INTRODUCTION: Breast cancer is the second most common type of cancer in the world, being more common among women and representing 22% of all new cancer cases every year. The sooner it is diagnosed, the better the chances of a successful treatment are. Mammography is one way to detect non-palpable tumors that cause breast cancer. However, it is known that the

14. Desenvolvimento de um Sistema de Auxílio ao Diagnóstico de Pneumonia na Infância Utilizando Visão Computacional / Development of a System of Aid to the Diagnosis of Pneumonia in Children Using Computer Vision
This work aims to develop a system to aid in the diagnosis of pneumonia by computer, termed pneumocad, which aims to identify chest radiographies compatible with the disease. Techniques were used for the recognition of patterns in textures through the decomposition of the wavelet transforms of the features extracted from the decomposition and classification

15. Abordagens multi-objetivo para o treinamento de redes neurais e seleção de características
Artificial neural networks have been successfully applied in solving problems such as functions approximation and patterns classification, where the extraction of a model can be difficult to see. The search for a model that best represents the problem makes the generalization ability the main concern in the training of artificial neural networks, a task that

16. Processamento e modelagem de dados geofísicos e imagens ASTER aplicados à interpretação geológica e prospecção mineral na Província Aurífera de Alta Floresta, MT / Processing and modeling of geophysical data and ASTER images applied to geological interpretation and mineral exploration in the Alta Floresta Gold Province, MT
The Alta Floresta Gold Province (AFGP) is located in the central-southern Amazon craton between the limits of the Ventuari-Tapajos (1.95-1.8 Ga) and Rio Negro-Juruena (1.8-1.55 Ga) provinces. In its eastern segment there are more than one hundred gold deposits hosted in volcanic and plutonic rocks and concentrated along the Peru-Trairao Belt in a NW-SE direc

17. ESTUDO DO EFEITO DA Malva sylvestris EM FIBROBLASTOS ESTIMULADOS POR LPS / Study of the effect of Malva sylvestris in fibroblasts stimulated with LPS.
The objective of this study was to develop biomonitoring of the hydroalcoholic extract of Malva sylvestris to evaluate the phytochemical profile beyond the effect of the hydroalcoholic extract of the plant on the release of IL-1β, TNF-α, LPS-induced nitric oxide, and finally, to assess possible toxicological effects of the extract. The activity of

18. Intercropping of corn, brachiaria grass and leguminous plants: productivity, quality and composition of silages
The present study was carried out with the objective to evaluate the productive and qualitative characteristics of forages produced in systems of intercropping of corn, brachiaria grass and different leguminous plants. Productivity, bromatological composition and the fermentative profile of the silages from the following treatments were evaluated: corn in ex

19. Characterization and in vitro release of cyclosporine-A from poly(D,L-lactide-co-glycolide implants obtained by solvent/extraction evaporation
Cyclosporine-A-loaded PLGA implants were developed intended for ocular route. Implants were prepared using solvent extraction/evaporation technique followed by casting of the cake into rods in a heated surface. XRD patterns showed that cyclosporine-A was completely incorporated into PLGA. FTIR and DSC results indicated alterations on drug molecular conformat

20. Ação do estado e a exploração de um recurso de acesso comum, a castanha do Brasil (Bertholletia excelsa): estudo de caso na comunidade amazônica de Tres Islas, na Região de Madre de Dios, Peru / States action and exploration of a common-pool resource, the Brazil nut (Bertholletia excelsa): case community study in Tres Islas, Madre de Dios Region, Peru
There are two remarkable characteristics during mankind history: the increasing capacity of human populations, exponentially in the last 300 years, to obtain energy and information and the increase in the complexity of the organization of their societies based especially on human interdependence. Economical and political pressures to satisfy the needs of the

21. Variações altitudinais na diversidade e composição em espécies de vespas e abelhas (Hymenoptera: Aculeata)
Distribution patterns of insects along elevational gradients have been described for many tropical mountains. According to the hypothesis of elevational gradient, species richness and abundance of species tend to decrease in higher altitudes. Aculeata is considered a monophyletic lineage of Hymenoptera order. They are important pollinators, but there are few

22. Plasmid patterns of efficient and inefficient strains of Bacillus thuringiensis against Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae)
Bacillus thuringiensis harbors genes encoding Cry proteins found in chromosomes or plasmids of different sizes (4-150 Mb). Although the smaller plasmids are more abundant in B. thuringiensis, their specific function is unknown. As for the megaplasmids, their main recognized function is to harbor cry genes, although the sequencing of some of these plasmids in

23. Estimating water application efficiency for drip irrigation emitter patterns on banana.
Abstract ? The objective of this work was to evaluate root and water distribution in irrigated banana (Musa sp.), in order to determine the water application efficiency for different drip irrigation emitter patterns. Three drip emitter patterns were studied: two 4-L h-1 emitters per plant (T1), four 4-L h-1 emitters per plant (T2), and five 4-L h-1 emitters
