13. Banco de dados geológico-geotécnicos com base em sondagens à percussão e uso de SIG: análise espacial da profundidade do lençol freático e do \ N IND.SPT\ para obras de fundação em João Pessoa - PB / Geological-geotechnical Database with SPT sounding data and GIS: spatial analysis of water table level and \ N IND.SPT\ values applied to foundation maps in João Pessoa - PB (Brazil)
Geological-geotechnical databases have been used as important assistant tools in urban and environmental management activities. However, the kind of information necessary for one to work with such tools may not always be available or easily supplied. This work concerns the generation of a Decision Support System undertaken through means of a Geographic Infor

14. VSB-30 sounding rocket: history of flight performance
Abstract: The VSB-30 vehicle is a two-stage, unguided, rail launched sounding rocket, consisting of two solid propellant motors, payload, with recovery and service system. By the end of 2010, ten vehicles had already been launched, three from Brazil (Alcântara) and seven from Sweden (Esrange). The objective of this paper is to give an overview of the main c

17. Characterization of traveling ionospheric disturbances over low latitude brazilian region associated to Perkins plasma instability generated at medium latitudes / Caracterização de distúrbios ionosféricos propagantes na região de baixas latitudes no setor brasileiro associados à instabilidade de plasma Perkins gerada em médias latitudes
With ground based measurements of OI 630 nm emission, by using all-sky imaging system installed at Cachoeira Paulista, we investigated the occurrence of specific events of Medium Scale Traveling Ionospheric Disturbances (MSTIDs), which occurred during nights geomagnetically quiet. Probably, these disturbances are associated with Perkins plasma instability ge

18. Evidências tectônicas no leste da Ilha do Marajó: integração de dados morfoestruturais e geofísicos / Evidence of tectonics in eastern Marajó Island: integration of morfoestructural and geophysical
Tem sido crescente o volume de investigações sugestivas de deformação tectônica no desenvolvimento dos sistemas deposicionais quaternários da ilha do Marajó. Isto é revelado pela combinação de informações sedimentológicas e estratigráficas com análises morfoestruturais. Entretanto, estudos de subsuperfície visando demonstrar a presença de es

19. Os "Sentidos do Trabalho" em duas Visões: São Paulo e Paris
This report is the outcome of an exploratory research of the meanings of work . The purpose was to carry out an opinions sounding, that is, to perform a global investigation of the meanings of work for two population samples from two different firms operating in the same field of activity. The sounding took place by means of a 36-question questionnaire invo

20. Análise dos perfis termodinâmicos da atmosfera e de parâmetros pré-convectivos obtidos pelo satélite GOES-10 / Analysis of termodynamic profiles and pre-convective parameters obtained form the GOES-10 satellite sounder data
Meteorological satellites provide a unique opportunity to obtain thermodynamic profiles in regions of the globe that do not have a dense meteorological upper air stations network, as in South America. Nowadays, the geostationary satellite GOES-10 makes the inference of temperature and mixing radio profiles every hour with a spatial resolution of 10 km over t

22. Lenght of theendometrial cavity as measured by uterine sounding andultrasonography in women of different parities / Avaliação do comprimento da cavidade uterina por meio da histerometria e ultrassom em mulheres nuligestas e com gestação previa
Introduction and objectives: Due to the controversies about the necessity of new shorter intrauterine devices (IUDs) for nulliparous women in order to reduce expulsion rate, the length of the endometrial cavity was measured in women with different parities by uterine sound and ultrasound. Materials and methods: We evaluated 570 women (17 to 52 years old) dis

24. Construção e validação de um receptor GPS para uso espacial
O Sistema de Posicionamento Global, conhecido mundialmente pala sigla GPS, é um sistema de radionavegação construído pelos norte-americanos com intenções militares, mas que encontraram, com o passar do tempo, muitas aplicações de uso civil. No Brasil, além do desenvolvimento de foguetes de sondagem, começam a aparecer projetos de construção de mi
