13. Atlas of Mexican Triatominae (Reduviidae: Hemiptera) and vector transmission of Chagas disease
Chagas disease is one of the most important yet neglected parasitic diseases in Mexico and is transmitted by Triatominae. Nineteen of the 31 Mexican triatomine species have been consistently found to invade human houses and all have been found to be naturally infected with Trypanosoma cruzi. The present paper aims to produce a state-of-knowledge atlas of Mex

14. Predicting the geographic distribution of Lutzomyia longipalpis (Diptera: Psychodidae) and visceral leishmaniasis in the state of Mato Grosso do Sul, Brazil
To understand the geographic distribution of visceral leishmaniasis (VL) in the state of Mato Grosso do Sul (MS), Brazil, both the climatic niches of Lutzomyia longipalpis and VL cases were analysed. Distributional data were obtained from 55 of the 79 counties of MS between 2003-2012. Ecological niche models (ENM) of Lu. longipalpis and VL cases were produce

15. Segmenting mammographic microcalcifications using a semi-automatic procedure based on Otsu's method and morphological filters
INTRODUCTION: Breast cancer has the second highest world's incidence rate, according to the Brazilian National Cancer Institute (INCa). Clinical examination and mammography are the best methods for early diagnosis. Computer-aided detection (CADe) and computer-aided diagnosis (CADx) systems are developed to improve mammographic diagnosis. Basically, CADx syst

16. Origin of samples of Cannabis sativa through insect fragments associated with compacted hemp drug in South America
Origin of samples of Cannabis sativa through insect fragments associated with compacted hemp drug in South America. Insects associated with a seizure of Cannabis sativa L. may indicate the origin of the illicit drug. Nevertheless, no work regarding this subject has been previously published for South America. In the present investigation, seven kilograms of

17. Ecologia trófica da ictiofauna e simpatria de espécies congenéricas no córrego da Lapa, bacia do Alto Paraná, estado de São Paulo, Brasil
Streams and rivers are loctic environments characterized for a strong and unidirectional water flow. These environments in general have the light incidence partial or totally obstructed by the canopy of the riparian vegetation showing a high dependence of allocthonus organic inputs. The stream fishes are usually small sized, with reproductive strategies adap

18. Avaliação da produção de sedimento na bacia hidrográfica do rio Potengi através do modelo SWAT
Anthropic disturbances in watersheds, such as inappropriate building development, disorderly land occupation and unplanned land use, may strengthen the sediment yield and the inflow into the estuary, leading to siltation, changes in the reach channel conformation, and ecosystem/water quality problems. Faced with such context, this study aims to assess the ap

19. Hábito alimentar da rã invasora Lithobates catesbeianus (Shaw, 1802) e sua relação com anuros nativos na Zona da Mata de Minas Gerais, Brasil / Feeding habits of the invasive frog Lithobates catesbeianus (Shaw, 1802) and its relationship with native anurans in the Zona da Mata of Minas Gerais state, Brazil
The American Bullfrog (Lithobates catesbeianus) was introduced into several countries for commercial breeding, settling invasive populations during this process. In Brazil the beginning of its farming occurred on the 1930 s, and currently invasive populations can be found in the South, Southeast and Central-West regions. It has a generalist feeding habit, an

20. Altitudinal distribution of birds in a mountainous region in southeastern Brazil
We studied the altitudinal distribution of 426 bird species in the Serra dos Órgãos, a mountainous region in southeastern Brazil. Thirty-four localities were visited between 1991 and 2009. Our study revealed a decline in bird species richness with elevation, although a smaller number of species was recorded at lower altitudes (below 300 m) possibly due to

Estudo de dinâmicas de paisagens no baixo curso do Rio Ipojuca, Pernambuco: potencial para sustentabilidade socioeconômica e cultural da região / Study of landscape dynamics in the lower course of Ipojuca river, Pernambuco: potential for the socioeconomic and cultural sustainability of the region
One of the greatest challenges in environmental planning and management is related to the need of overcoming the different regionalization forms. Since the beginnings, several are the unifying the basis efforts which allow a conciliatory limits management and space interventions. This project aims to analyze the landscape dynamics of the lower course of Ipoj

22. Detecção de faces humanas em imagens coloridas utilizando redes neurais artificiais / Detection of human faces in color images using artificial neural networks
The task of finding faces in images is extremely complex, as there is variation in brightness, backgrounds and highly complex objects that may overlap partially in the face to be found, among other problems. With the advancement in the field of computer vision techniques latest image processing and artificial intelligence have been combined to develop more e

23. ASPECTOS ECOLÓGICOS DO CERVO DO-PANTANAL Blastocerus dichotomus (ILLIGER, 1815) (MAMMALIA: CERVIDAE): ANIMAIS REINTRODUZIDOS E OU NASCIDOS NA ESTAÇÃO ECOLÓGICA DE JATAÍ, NORDESTE DO ESTADO DE SÃO PAULO, MUNICÍPIO DE LUÍS ANTÔNIO / ECOLOGICAL ASPECTS OF MARSH DEER Blastocerus dichotomus (ILLIGER, 1815) (MAMMALIA: CERVIDAE): ANIMALS REINTRODUCED AND OR BORN IN THE ECOLOGICAL STATION OF JATAÍ, NORTHEAST OF THE STATE OF SÃO PAULO, CITY OF LUIS ANTONIO
Marsh deer (Blastocerus dichotomus) is a large mammal and is considered the largest deer native to South America, this species is extinct in 60% of its historic range that included the natural flood plain of the great rivers between the southern Amazon and northern Argentina. Despite being threatened with extinction, little is known about the ecological aspe
