15. Integration of remote sensing (SRTM and RADARSAT-1) geology, gravimetry and magnetometry date as an aid to a morphostructural study in the Uatumã River area, Amazon Basin / Integração de dados de sensoriamento remoto (SRTM e RADARSAT-1), geologia, gravimentria e magnetometria para estudo morfoestrutural da área do Rio Uatumã, Bacia do Amazonas
Drainage network automatically extracted from a SRTM digital elevation model was combined with geologic, gravity and magnetometry data for morphostructural study in the region of the Uatumã River, Amazonas Sedimentary Basin. Data interpretation allowed the identification of different drainage patterns, including trellis, pinnate, contorted, annular and angu

16. Percevejos castanhos (Hemiptera, Cydnidae, Scaptocoris): aspectos morfológicos, ecológicos e comportamentais / Burrowing bugs (Hemiptera, Cydnidae, Scaptocoris): morphological, ecological and behavioral aspect
The objective of this study was to elucidate morphological, ecological and behavioral aspects of the burrowing bugs (Scaptocoris). Population dynamic studies, sexual dimorphism, wing polymorphism, and acoustic communication were investigated on different species of Scaptocoris. Studies on population dynamics and vertical distribution in the soil were carried

17. An ecological and economical zoning proposal for the Environmental Protection Area of Tambaba, in the state of Paraíba / Proposta de zoneamento ecológico econômico para a área de proteção ambiental (APA) estadual de Tambaba - Paraíba
This work is a proposal of an ecological and economical zoning (ZEEZoneamento Ecológico Econômico, in Portuguese) for the Environmental Protection Area (APAÁrea de Proteção Ambiental, in Portuguese) (both categories used by IBAMA, the Brazilian Institute for the Environment and Natural Resources) at Tambaba on the littoral of Paraíba state. The APA of

18. Processamento e interpretação de dados 2D e 3D de GPR :aplicações no imageamento de feições kársticas e estruturas de dissolução no campo de petróleo de Fazenda Belém-CE
In Fazenda Belém oil field (Potiguar Basin, Ceará State, Brazil) occur frequently sinkholes and sudden terrain collapses associated to an unconsolidated sedimentary cap covering the Jandaíra karst. This research was carried out in order to understand the mechanisms of generation of these collapses. The main tool used was Ground Penetrating Radar (GPR). Th

19. Comportamento e correÃÃo da radiaÃÃo solar difusa obtida com o anel de sombreamento
This paper shows the comportment of solar radiation global, direct and diffuse radiation at Cascavel, classifies the skyâs cover in function of the cloudiness index and studies the applicability of the numeric correction of RICIERI (1998) on diffuse radiation measured with a shadow ring. The research was done at meteorological experimental station of UNIOES

21. Analyses of tornadoes events in Santa Catarina state, Brazil: synoptic features and datamining. / Análise de episódios de tornados em Santa Catariana: caracterização sinótica e mineração de dados
This work deals with the prevailing synoptic features associated to tornadoes events in Santa Catarina state during the 1976-2000 period. The analysis was done using the National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) reanalysis, satellite images from GOES-8 and TRMM and conventional meteorological data. The

22. Análise geométrica e cinemática dos metassedimentos da Klippe de Ijaci, Sul de Minas Gerais / não informado pelo autor.
The present work was undertaken in the Ijaci region, southern Minas Gerais state, and involved geological maping, emphasizing geometric and kinematic analysis of the structures in the meta-sedimentary cover. Two litostructural domains were distinguished: the basement domain, composed by granitic and granodioritic orthogneisses, with a steep plunging EW tecto

23. DISPERSION CHARACTERISTICS OF MICROSTRIP LINES IN THE SPECTRAL DEMAIN / DETERMINAÇÃO DAS CARACTERÍSTICAS DE DISPERSÃO DE LINHAS MICROSTRIP ATRAVÉS DA ANÁLISE NO DOMINIO ESPECTRAL
The boundary value problem associated with the shielded microstrip-line structure is formulated in terms of a rigorous hybrid-mode representation, superposition of the TE and TM fields. The resulting equations are subsequently transformed, via the application of Galerkin¿s method in the spectral domain, to yield a characteristic equation for the dispersion

24. Gradient Plate Bioassay for Tyrothricin and its Application to Dentifrices
A bioassay for tyrothricin, based on a procedure used by Szybalski in bacterial resistance studies, was developed. Replacement of the tube dilution assay with this procedure represented economy in time and equipment, with a resultant increase in productivity. The procedure involved preparation of special agar plates which provided graded concentrations of ty
