13. Contribution to the tecnicas of location of wells in lands of crystalline rocks in the half-barren Brazilian / ContribuiÃÃo Ãs tecnicas de locaÃÃo de poÃos em terrenos de rochas cristalinas no semi-Ãrido brasileiro
Geological and geophysical studies were accomplished in the areas of Carnaubeira da Penha and Alagoinha in the semi-arid region of Pernambuco where Neo and Mesoproterozoic crystalline rocks occur. The study aimed at a better understanding of the variables upon which well yields are dependent in hard rock territories, in order to improve well site selection t

14. Thermospheric meridional winds inferred from ionospheric soundings / Ventos termosféricos meridionais inferidos por meio de sondagens ionosféricas
Nighttime thermospheric neutral winds aligned to the magnetic meridian are derived from F-region height variations, over two equatorial stations, Manaus (2.9°S, 60.0°W, dip latitude 6.06°N) and Palmas (10.2°S, 48.2°W, dip latitude 6.2°S) and one low latitude station, São José dos Campos (23.2°S, 45.9°W, dip latitude 18.26°S), in the Brazilian sect

15. A study of single and compound interplanetary magnetic structure characteristics and their geoeffectiveness / Estudo de características e geoefetividade de estruturas magnéticas interplanetárias simples e compostas
The aim of this work is to study characteristics and geoeffectiveness of interplanetary shock waves, sector boundary crossings, magnetic clouds and combinations of these single interplanetary magnetic structures for the solar wind in situ observational period, from 1964 onwards. A seasonal variation in the interplanetary shock occurrence near Earth was found

16. O metodo de empilhamento CRS : refinamento dos parametros e aplicações
The common Reftection Surface (CRS) method extends the well established Normal Move-Out (NMO) method, allowing the stacking process to be applied to data arranged in settings more general than the common midpoint (CMP) gathers. For that aim, the CRS method uses the general hyperbolic moveout, which depends on the classical NMO velocity and some other paramet
