1. Efeitos da arbórea introduzida Hovenia dulcis Thunb.(Rhamnaceae)sobre o componente árbóreo-arbustivo regenerante da floresta Atlântica no Sul do Brasil
Biological invasions by Hovenia dulcis Thunb., a tree from Asia, have been reported for Africa and South America. The present work aimed to evaluate the effects of the establishment of this exotic species on abundance, richness, species composition, growth, successional categories and beta diversity of natural regeneration in the Atlantic Rain Forest. Thus,

2. Uma fundamentação para sinais e sistemas intervalares
Neste trabalho utiliza-se a matemática intervalar para estabelecer os conceitos intervalares das principais ferramentas utilizadas em processamento digital de sinais. Mais especificamente, foram desenvolvidos aqui as abordagens intervalares para sinais, sistemas, amostragem, quantização, codificação, transformada Z e transformada de Fourier. É feito um

3. Estudo clínico e eletromiográfico de músculos cervicais em mulheres com e sem disfunção temporomandibular / Clinical and electromyographic study of cervical muscles in women with and without temporomandibular dysfunction
The temporomandibular disorder (TMD) among many symptoms causes orofacial pain. It is also common, the incidence of neck pain complaint, which leads to overlapping signs and symptoms of temporomandibular joint (TMJ) and cervical spine. This study aimed to compare the patterns of electromyographic activity and the presence and severity of pain in the cervical

4. Dance circle and quality of life in womem with mastectomy : a pilot study / Dança circular e qualidade de vida em mulheres mastectomizadas : um estudo piloto
Introduction: The woman with breast cancer lives deeply the suffering of the illness in a peculiar way, therefore the place where it is attacked the disease is a symbol of femininity, sexuality and aesthetic, being targeted of contemplation. With the mastectomy, many feelings and sufferings are unchained, modifying the quality of life. After surgery there is

5. Comparação de modelos receptores GPS para utilização na agricultura de precisão.
ABSTRACT: After the liberation of Selective Availability (S/A) several GPS receivers started to have enough accuracy or precision for work with grid sampling in Precision Agriculture. There are few articles describing the accuracy and precision of these receivers. The objective of this work was compared and calculated the accuracy of two models very used for

6. Variação do espaçamento entre faixas de colheita na geração de mapas de produtividade.
RESUMO: Este trabalho avaliou o efeito do espaçamento entre faixas de colheita na geração de mapas de produtividade da cultura de milho. Avaliou-se a correlação existente entre um mapa confeccionados a partir da colheita da área total ( referencia) e outros 5 mapas, onde foram retiradas 2, 4, 6, 8 e 10 faixas de colheita. O mapa referencia foi confecci

7. Geração de mapas de produtividade para experimentos com milho no âmbito de fazenda.
ABSTRACT: Many farmers do not use precision agriculture tools due to high equipment costs and lack of knowledge about this new approach. A number of farmers have, however, conducted on-farm experiments without the help of these new and still expensive tools. One of most important equipments for precision agriculture practices is the crop yield monitor. It ca

8. Fatores Formadores da Paisagem Litorânea: A bacia do Guaratuba, São Paulo-Brasil / FORMATION FACTORS OF THE COASTAL LANDSCAPE: THE CASE OF THE GUARATUBA WATERSHED, SÃO PAULO, BRAZIL.
This study aims to characterize and correlate elements of the biotic-physical environment, drainage, geology, landform, vegetation cover, soil and land use by means of interpretation of aerial photographs, satellite images and field work. It also aims to test the technique of circular sampling the drainage network for identifying soil mapping units in the Se

9. Orientação de voo de lepidopteros migratorios na região de Carajas, Para
In this study the migratory behavior, of diurnal lepidopterans in Carajás, Pará, was investigated. The study was undertaken during July-August/84 and July-September/85 in the southern Amazonian dry season. Quantitative sampling of flight direction was done in several different sites, at different periods of the day, and throughout the season, together with

10. Multiple independent origins of mitochondrial gene order in birds
Mitochondrial genomes of all vertebrate animals analyzed to date have the same 37 genes, whose arrangement in the circular DNA molecule varies only in the relative position of a few genes. This relative conservation suggests that mitochondrial gene order characters have potential utility as phylogenetic markers for higher-level vertebrate taxa. We report dis

11. Tracking of single fluorescent particles in three dimensions: use of cylindrical optics to encode particle position.
We present a novel optical technique for three-dimensional tracking of single fluorescent particles using a modified epifluorescence microscope containing a weak cylindrical lens in the detection optics and a microstepper-controlled fine focus. Images of small, fluorescent particles were circular in focus but ellipsoidal above and below focus; the major axis
