Drenagem e traces tectonicos na Regiao Norte-Ocidental de Estado de Sao Paulo.

A detailed statistical study of the drainage was made as an indirect means for interpreting the modern tectonic traits of the area. Over 1000 measurements of direction of fluvial courses were made from maps and air photos. These data allowed the diagnosis of the existence of a regional tectonic pattern, printed on the basaltic rocks, and its influence on the drainage adjustment as well as a more local control exerted by structures present in the Bauru Group rocks. -from English summary

Caracteristicas gerais e classificacao de solos basalticos da regiao Central do Estado de Sao Paulo.

Giving a special emphasis on soil classification relative to their positions in the landscape, five soil profiles in the Barra Bonita-Jau area were characterized through morphological, granulometric and chemical routine soil analysis. It was observed that the soil structure gradually changes from strong blocks with cutans (lowlands and smooth parts - Jau). In this direction, the silt/clay ratio and the base saturation is reduced, and the aluminium saturation increases. -from English summary

Relacoes entre a concentracao espacial dos ramos industriais 'motrizes' e o desenvolvimento regional: o caso do Estado de Sao Paulo.

This paper, having its conceptual basis in the Theory of Growth Poles, by F.Perroux, tests the effective existence of correlation between the spatial incidence and concentration of the 'propulsive' industrial groups and the industrial growth as a whole and the demographic increase. The selected case study was the state of Sao Paulo and data used was the 1970 census. As consequence of the techniques applied a industrial regionalization of the 'paulista' space was obtained, showing few areas of intense industrial concentration, especially of 'propulsive' groups, with multiple growth poles, and large areas with industrial rarefaction, with little or no poles.-after English summary

Condicionamento geologico da agua subterranea em Sao Jose,do Rio Preto, SP.

A study of the geological characteristics of the Buaru Group basaltic substratum and stratigraphical unities was carried out, taking into account the groundwater exploration in S.Jose do Rio Preto area. The presence of the tectonic structures in this substratum exercised a profound influence on the sedimentation of the Bauru Group and on the variations in the hydrological properties of the sediments of the area.-English summary

Comportamento espacial da cultura canavieira no Estado de Sao Paulo, 1980

Data from the agricultural and Cattle Raising Census for 1980 show that most of the sugar cane producing counties lie in the administrative regions of Campinas, Ribeirao Preto and Sao Jose do Rio Preto. A comparison with the 1975 data shows two important facts; 1) an increase of the cultivated area in 118 counties and 2) an increase in the number of counties with area under sugar cane. There was also an expansion in the sub-regions of Catanduva, Assis and Ourinhos. Nevertheless, Piracicaba, Araraquara, Ribeirao Preto, Jaboticabal and Jau, have continued to be important sugar cane producing nuclei in the State since 1960. -from English summary

Tectonica do Complexo Varginha na regiao de Sao Joao da Boa Vista (SP)

Migmatites, high-grade gneisses and granitoids represent the most important Precambrian rocks of Sao Joao da Boa Vista region. Structures are interpreted as due to low-angle oblique non-coaxial ductile shear, developed under conditions of amphibolite facies. Transcurrent ductile shear zones and associated drags modify the foliation and lineations orientations. A first phase of migmatization related to anatexis seems to be developed before or early during the thermo-tectonic process. A second one is syntectonic, and represents the main regional phase. Joints and faults represent the brittle features, the faults marked by cataclastic rocks and intense retrometamorphism along the main zones. -from English summary

Razao Sr:Ba:Rb e tipologia de zircao em granitoides dos Estado de Sao Paulo, Parana e Minas Gerais

Chemical (Sr:Ba:Rb) and zircon typology data from the Nazare Paulista, Mairipora/Cantareira, Cunhaporanga, Tres Corregos, Morungaba, Socorro, Itu, Graciosa and Serra Carambei granitoid complexes from the states of Minas Gerais, Sao Paulo and Parana (SE/S Brazil) are presented and discussed. By the zircon typology method these complexes are refered, respectively, to the 2nd crustal, 3rd crustal/low temperature C-A, low temperature C-A, medium temperature C-A, medium/light temperature C-A, K-SA/Alkaline and alkaline series which are considered as generated under increasing temperature associated with a progressive major participation of mantle material. All these series display different positions and behaviour in the Sr:Ba:Rb diagram which reinforces the use of the zircon typology method in the study of granitoids. -from English summary

Virulence factors in Escherichia coli strains isolated from pigs in the Ribeirao Preto region, State of Sao Paulo, Brazil.

Three-hundred faecal swabs were obtained from pigs with diarrhoea in farms located in different areas of the Ribeirao Preto region in the State of Sao Paulo. One-hundred Escherichia coli strains were isolated and tested for production of thermolabile (TL) and thermostable (STRa and STb) enterotoxins, and for the presence of colonization factors F4, F5 and F6. The strains were also tested for sensitivity to 14 antibiotics and chemotherapeutic agents. Twenty-four Escherichia coli strains produced enterotoxin STb, 5 produced LT and 3 produced STa. In the mannose-resistant haemagglutination reaction, one strain reacted positively with sheep, chicken, horse and human red blood cells and another reacted positively with guinea pig, sheep, chicken, horse and human red cells. However, both strains were negative for colonization factors F4, F5 and F6 when submitted to the slide agglutination test. All Escherichia coli strains were resistant to at least one antibiotic, the highest percentages being obtained for resistance to penicillin, tetracycline and cephalotin. In addition to the importance of the virulence factors normally encountered in enterotoxigenic Escherichia coli strains from pigs, the present results show the possible existence of new colonization factors other than F4, F5 and F6 participating in E. coli-induced pigs colibacillosis in the Ribeirao Preto region.

Modelos geotectonicos aplicados ao Pre-Cambriano superior do NE do Estado de Sao Paulo e areas adjacentes do Estado de Minas Gerais: uma discussao

The main geotectonics models presented during the last 25 yr to explain the evolution of the Late Precambrian (Brasiliano Cycle) terranes of the NE of the State of Sao Paulo and the adjacent areas of the State of Minas Gerais, domain of the Guaxupe Massif, SE Brazil, are presented and discussed. The models can be classified in: 1) classic; 2) mainly ensialic; and 3) applications of the plate tectonic theory. -from English summary
