Mapeamento de Paleosuperfícies associadas a identificação de depósitos supérgenos de cobre como ferramenta de exploração mineral na região de Itapeva e Ribeirão Branco- Vale do Ribeira, estado de São Paulo, Brasil

A few examples of supergene ore formation and their interaction with morphogenesis (palaeosurfaces) and weathering mineralogy are discussed. Geomorphological and mineralogical records to characterize palaeosurfaces associate the weathering of primary minerals and their relationship with concentrations of cooper and iron ore deposits in southeastern state of São Paulo, Brazil. We have distinguished two palaeosurfaces generated by several weathering phases and controlled by the geological framework. The first and oldest upper palaeosurfaces (900 - 1000 m a.s.l.), situated in Riberão Branco (Alto do Brancal), were developed on silico-limestones. It is formed by typical iron laterites enriched by secondary products of cooper. The second and younger level palaeosurfaces located in Itapeva (Santa Blandina and Bairro do Sambra). This palaeosurface is formed by copper percolating through the weathered rock (saprolite). Other features can be observed like neo-formed products in laterites. They are classified into two types: clay like silico- cupriferous products (with noticeable amounts of iron) and copper minerals (crysocolla, in their flat slopes). These features allowed the presence of copper ores and their morphogenesis control will help in the exploration and prospecting of supergene ore mineral.

Existe utilização efetiva dos recursos vegetais conhecidos em comunidades caiçaras da Ilha do Cardoso, estado de São Paulo, Brasil?

This study aims to investigate if plant resources are effective used by caiçaras' communities of the Cardoso Island. We also want to verify if the biogeografic origin of plants, their uses and socioeconomic factors influence the locals' knowledge. We carried out 51 semi-structured interviews with people who have been living there for at least 5 years, who were older than 18. We concluded that the interviewees' knowledge is still diverse and that most of the plants known are used by them (82%). Native plants are largely known, while the exotic ones are the most used (95%). Knowledge and use vary according to the use of plants, although they were very similar, considering the interviewees' age and gender. We also realized that housewives use a large quantity of medicinal plants, which are mainly the exotic ones. Fishermen know and use native plants, usually for handicraft purposes. The environmental guides and people, whose job is tourism related, have a similar knowledge, especially about medicinal plants, which are less used when compared with the other professional activities.

Distribuição e abundância de larvas de Simulium spp.em córregos do estado de São Paulo nos diferentes níveis de qualidade da água

The aim of this work was to determine the distribution and abundance the species of Simulium: in 5 streams of the north coastal region of the state of São Paulo. Simulium larval and water samples were collected every 2 weeks in summer and winter, 2001. The larval were collected on artificial substrates (triplicate) preserved in alcohol (70%) and after analyzed quantitative and qualitative. From the streams the values of temperature, dissolved oxygen, conductivity, pH and stream discharge were measured. The contents of total nitrogen and dissolved nitrogen, ammoniacal nitrogen, nitrate, nitrite, orthophosphate, dissolved phosphorus and total phosphorus were determined in the laboratory. Water quality has great influence in the distribution and abundance of the species. S. pertinax was more abundant in streams without or with low levels of pollution, S. inaequale in streams more polluted and S. incrustatum in intermediary levels of pollution. S. pertinax was the species more abundant with 57.5% of presence in the samples, the second more abundant was S. inaequale with 42.1% of presence and S. incrustatum was rare with 0.4% of presence. The larval abundance was lower in the polluted environment. © 2012 by Unisinos.

Ocorrência de anormalidades morfológicas externas em caranguejos marinhos (Decapoda, Brachyura) no litoral norte do estado de são paulo

Deformities and abnormalities in crustaceans have been associated to genetic problem, which occurred during molt process, damage caused by ectobionts, predators or environmental stress caused by chemical wastes. Some crab specimens collected in the São Paulo littoral were found having body abnormalities. They belong to the following crab species: Callinectes ornatus (Ordway, 1863), Arenaeus cribrarius (Lamarck, 1818) and Leurocyclus tuberculosus (H. Milne Edwards; Lucas, 1843). Samplings were performed by trawling during July 2008, August and October 2009 at the Ubatuba region, São Paulo State, Brazil. Body abnormalities were verified in the cheliped dactyl (C. ornatus an adult male), carapace deformities (A. cribrarius an adult male) and abdominal alterations (C. ornatus an adult female; L. tuberculosus an adult male and an ovigerous female). The record and analysis of such occurrences can help in the distinction of natural or human impact caused alterations. In this way, the occurrence study of this kind of body alterations could provide tools in order to control unprotected environmental areas, as well as bring subsides to understand the unusual variations during the ontogeny of important species in the benthic community.

Mudanças ontogenéticas na dieta de Oreochromis niloticus and Tilapia rendalli da represa de Barra Bonita (rio Tietê, Estado de São Paulo, Brasil)

The Nile Tilapia, Oreochromis niloticus, and the Congo Tilapia, Tilapia rendalli, are important members of the African cichlids, and have been introduced to many Brazilian lakes and reservoirs. These species exhibit a large feeding flexibility and may modify their habits during their growth. In the Barra Bonita reservoir, these species are well adapted, representing more than 80% of fish. This study aimed to analyze ontogenetic variation with regard to the diet of these species in this important reservoir. Samples were taken monthly, from March 2007 to February 2008, in Anhembi, São Paulo State. Both species were analyzed by grouping individuals according to size classes. The coexistence of these species was observed in this environment, to which fish were introduced, as well as discreet differences in diet, being that Oreochromis niloticus was considered as an detritivorous, since the detritus was constant in the diet of almost all size classes, and presents some changes in its diet according to the different size classes. While T. rendalli may was defined as herbivorous, and the contribution of food resources to the diet of T. rendalli seems to be different from that of O. niloticus along the size classes.

Infecção pelo vírus da diarreia viral bovina em vacas gestantes abatidas no Estado de São Paulo-Brasil

The most important pathogens in the bovine livestock nowadays in the virus of the viral diarrhea mainly for triggered clinical manifestations related to the reproductive sphere. The infection in pregnant females, may result in abortions, embryonic resorptions, fetal mummification, birth of weak and malformation of the cattle. Moreover, their birth with persistently infected and immunotolerant virus, which the source of infection and dissemination of their disease. Nowadays, the complexity of the diagnosis and consequently its pathogenesis are tilted in the genotypic differences agent. So, this study aimed to verify the occurrence of the BVDV-1 (SINGER) and BVDV-2 (VS-253) genotypes in cows and their respective fetuses, slaughtered in an abattoir in the State of Sao Paulo. Through blood serum, using virus neutralization technique. All in all, 52,51% (115/219) of the cows which were tested reacted, but no fetus (0/219) reacted, to its virus neutralization. Through this cross-examination we observed that 42% (92/219) of cows reacted for both BVDV-1 and BVDV-2. Furthermore 4,10% (9/219) of them reacted only to the genotype BVDV-1 and 6,39% (14/219) responded only to the genotype 2 of BVDV. Therefore it was noticed that both strains are widespread in the regions studied, which justifies the use of different antigens to avoid false-negative diagnosis. Finally antibodies showed no fetus or fetal abnormalities, it is already developed and can be considered immunocompetent, independent child born to a reagent.

Avaliação de custos das internações de gestantes diabéticas de um Hospital Universitário do interior de São Paulo

This study aimed at identifying the hospitalization costs of pregnant women with Diabetes Mellitus (DM) at a University Hospital. It is an observational, quantitative study with descriptive data analysis. The direct and indirect costs available in the institution were identified in order to determine the hospitalization costs for patients diagnosed with DM during pregnancy and childbirth. By means of descriptive statistics, it was observed that 63.46% of the patients had caesarean delivery; the mean total cost was R$ 362.93 (U$ 218.10)/hospitalization during pregnancy, R$ 2,642.65 (U$ 1,588.13)/hospitalization for caesarean delivery, and R$ 2.319.77 (U$ 1,394.09)/hospitalization for vaginal delivery. It was concluded that the analysis of hospitalization costs for patients with DM is of utmost importance, since they are highcomplexity hospitalizations that require a large number of interventions, increasing thus the service costs.

Análise da compacidade do solo na área urbana de Bauru/ Estado de São Paulo utilizando Ensaios de Penetração Padronizado e sísmica de refração

This study was done to determine compactness of soil strata in the urban area of Bauru, central São Paulo State using standard penetration test (SPT) and seismic refraction methods. Frequency distribution within boreholes was measured every meter to a depth of 30 meters. The geometric mean of standard penetration test values was computed every meter. A biplot graph showing the relationship of SPT with depth indicates soil stratification. In addition, five sections of seismic refraction values, which also indicate the compactness of soil strata, were obtained. A comparison of the two methods shows significant correlation between the results obtained from each.

Geotermometria das águas hipertermais do Sistema Aquífero Guarani no estado de São Paulo

Several geothermometers have been employed to determine the expected temperature in the groundwater reservoirs, most part of them based on the chemical equilibrium between thermal groundwaters and minerals which constitute the aquifer framework. Based on this principle, groundwater from Guarani Aquifer System, which presents temperatures upon to 38°C, classified as hyperthermal by the Brazilian Mineral Water Code, had their chemical composition evaluated with the main purpose to determine the expected temperatures in the reservoir based on the application of several geothermometers. These groundwaters can be classified as Na-HCO3 type evolving to Na-HCO3-Cl-SO4 type due the increase in sulphate and chloride concentrations. Measured groundwater temperatures show a good correlation with the depth of the aquifer, indicating an average geothermal gradient of 27.7°C/km. The lowest geothermal gradients, bellow 25°C/km, are observed in the central portion of the study area; meanwhile the highest gradients are observed in NE and W portions of the study area. Quartz equilibrium based geothermometers return temperature over the measured temperatures, meanwhile chalcedony geothermometer returns temperatures near the measured in the wells, except for the wells located in the area which presents the lowest geothermal gradients. The geothermometers based on the equilibrium between Na/K have returned temperatures diverse from the measured at the field, meanwhile the geothermometer based on the equilibrium between Na/K/Ca has presented good match with groundwater which present temperatures under 50°C, due the thermodynamic equilibrium between these waters and feldspars. Geothermometers show evidences about mixtures between groundwaters from GAS and underlying units, especially in wells located in the SW portion of the study area.

Falhas reprodutivas associadas com a presença de do vírus da artrite-encefalite caprina, toxoplasma gondii e neospora caninum em caprinos no estado de São Paulo, Brasil

This study aimed at assessing the occurrence of antibodies against the caprine arthritis-encephalitis virus (CAEV), Toxoplasma gondii and Neospora caninum, as well as the associations between the presence of antibodies and the occurrence of reproductive failures in goats. Serum samples were collected from 923 goats of both sexes, over 3 months of age, from 17 dairy farms located in different municipalities of São Paulo State, Brazil. Infections by T. gondii, N. caninum and CAEV were evaluated by indirect methods of diagnosis based on indirect fluorescence antibody test (IFAT), Neospora agglutination test (NAT), and agar gel immunodiffusion (AGID), respectively. A survey was conducted on the farms to obtain information about reproduction dates (abortions, stillbirths and births of weak and premature kids) and zoosanitary management. Antibodies against CAEV, T. gondii and N. caninum was found in 37.81%, 23.62% and 17.23% respectively. There was no significant association between the presence of anti-CAEV antibodies and CAEV/T. gondii or CAEV/N. caninum co-infection, suggesting that CAEV does not predispose goats to infection by these agents. However, when CAEV/T. gondii (p<0.01) or CAEV/N. caninum (p<0.001) co-infection was present, the occurrence of reproductive failures was significantly higher what could indicate that CAEV-induced immunosuppression may predispose goats to develop the clinical symptoms of toxoplasmosis and neosporosis increasing the risks of the reproductive failures.

Estudo da mcrobiota fúngica gastrintestinal de morcegos (Mammalia, Chiroptera) da região noroeste do estado de São Paulo: Potencial zoonótico

Bats are hosts of a rich diversity of microorganisms. Many studies indicate a close link between bats and fungi with pathogenic potential, especially for living in environments such as caves, caverns and hollow trees, favorable to the maintenance and spread of fungi. The objective was to study the gastrointestinal mycoflora of bats. Of the 98 samples belonging to 11 species of bats coming from 15 studied cities, 20% of the species were Carollia perspicillata, 19% Artibeus lituratus, 17% Molossus rufus, 13% Glossophaga soricina, 9% Nyctinomops macrotis, 8% Molossus molossus, 7% Desmodus rotundus, 2% Lasiurus ega and 1% Eptesicus furinalis, Myotis nigricans and Tadarida brasiliensis. The genus Aspergillus sp. was isolated from 29% of the samples, followed by 6% Microsporum sp. and Penicillium sp. 4% Trichophyton sp. and zygomycetes and 2% Fusarium sp. Of yeast species, 14% were from Rhodotorula sp., 10% Candida sp. and 2% Cryptococcus sp., 22% of isolates remained unidentified. All 82 cultures of organs were negative for Histoplasma capsulatum. There was a statistically significant association between the results of microbiological culture and bat species (p < 0.05). We conclude that the bats can act as disperser agents of fungi with pathogenic potential, although other studies should be performed to establish strategies to identify the main factors correlated with the growth and spread of microorganisms in nature and implication of bats in the epidemiological cycle.

Coccidiose em cães e gatos do município de andradina, estado de são paulo, Brasil

Coccidiosis is one of the most common parasitic diseases in dogs and cats in all the world. The aim of this study was to determine the occurrence of this parasitosis in dog and cat population at the Municipality of Andradina in the State of São Paulo, from 2007 to 2009. Fecal samples from 97 cats and 93 dogs were analyzed by using the techniques of flotation in saturated sodium chloride and spontaneous sedimentation. The species were classified according to morphology of the oocysts. Cystoisospora fecal oocyst found in 71.1% (69/97) of the cats, and simple infection by C. rivolta and C. felis occurred respectively in 41.0% (16/39) and 20.5% (8/39) animals, with P ≥ 0.2319. In 39.7%(37/93) of the dogs was found positive for Cystoisospora spp. And the species C. canis identified in the largest proportion (63.9%) with P = 0.0005. From the results, we conclude that dogs and cats had high incidence of infection Cystoisospora, being C. canis and C. rivolta most observed species, respectively.

Three steps were outlined from the analysis of the Proposal: 1) identify the subjects for each bimester, 2) analyze the teacher's book in terms of learning situations and their development, and 3) plan educational strategies and resource adaptations. Ten teaching strategies were planned, four new resources were indicated and two teaching resources were adapted for the classes. The activities of the Curriculum Proposal allow strategy planning aimed at the participation of students with visual disabilities together with students without disabilities.

Soroprevalência da infecção chagásica em indivíduos jovens em hemocentro no Estado de São Paulo, Brasil

This study aimed at estimating the number of cases of non-negative serological reactions to Chagas disease in blood donors at the Blood Center of Botucatu, São Paulo, Brazil, from 2003 to 2010 and at relating them to their cities of origin. Five hundred and seventy-four non-negative results for Chagas disease were evaluated. Of these, 371 (64.8%) were reagent, and 203 (35.4%) were inconclusive. The prevalence of Chagas disease in blood donors was 0.05%. There were, on average, 72 cases/year, and a prevalence of males was observed (64.8%). Forty-three (7.49%) individuals were 18 to 30 years old; 92 (16.02%) were 31 to 40; 147 (25.61%) 41 to 50, and 292 (50.87%) were older than 50 years. It was observed that 29.3% of females with reagent serology were at their fertile age (18 and 45 years). The majority of donors were originally from cities in the southwestern and central regions of São Paulo, but individuals from other states contributed with 20%. The provenance of most donors was the city of Botucatu/SP, followed by the city of Taquarituba/SP. Therefore, the profile of donors at this blood center favors the occurrence of a larger number of non-negative serological reactions. Although there has been a significant reduction in the number of new cases/year for this disease, it is still a public-health problem, and results suggest the need for new epidemiological assessments in the studied region.
