    The purpose of this research was to study the geochemical behavior of radionuclides and heavy metals in soils of agricultural use at Corumbatai River basin (SP). The natural concentration and variability in sedimentary rocks at Corumbatai river basin follow the trend Ca > Mg > K > Na, with the concentration of heavy metals and radionuclides. The distribution of exposure rate in soils shows the occurrence of higher values towards south of the Corumbatai river basin, region where are applied phosphate fertilizers, amendments and 'vinhaca' in sugar cane crops. Heavy metals and radionuclides incorporated in phosphate fertilizers and amendments are annually added during the fertilization process in the sugar cane crops, but if they are utilized in accordance with the recommended rate, they do not rise the concentration levels in soils up to hazards levels. Thus, they are lower transferred from soils to sugar cane at Corumbatai river basin, not offering hazard to the ecosystem and animal or human health. (author)

    The wind behavior of a region can be described by frequency distribution that provide information and characteristics needed for a possible deployment of wind energy harvesting in the region. These characteristics, such as the annual average speed, the variance and shunting line standard of the registered speeds and the density of aeolian power average hourly, can be gotten by the frequency of occurrence of determined speed, that in turn must be studied through analytical expressions. The more adjusted analytical function for aeolian distributions is the function of density of Weibull, that can be determined by numerical methods and linear regressions. Once you have determined this function, all wind characteristics mentioned above may be determined accurately. The objective of this work is to characterize the aeolian behavior in the region of Botucatu-SP and to determine the energy potential for implementation of aeolian turbines. For the development of the present research, was used an Monitorial Young Wind anemometer of Campbell company installed a 10 meters of height. The experiment was developed in the Nucleus of Alternative Energies and Renewed - NEAR of the Laboratory of Agricultural Energize of the Department of Agricultural Engineering of the UNESP, Agronomy Sciences Faculty, Lageado Experimental Farm, located in the city of Botucatu - SP. The geographic localization is defined by the coordinates 22 deg 51' South latitude (S) and 48 deg 26' Longitude West (W) and average altitude of 786 meters above sea level. The analysis was carried through using registers of speed of the wind during the period of September of 2004 the September of 2005. After determined the distribution of frequencies of the hourly average speed of the wind, it was determined function of associated Weibull, thus making possible the determination of the annual average speed of the wind (2,77 m/s), of the shunting line standard of the registered speeds (0,55 m/s), of the

    This work presents the first results obtained on the investigation of the behavior of uranium and radium radioisotopes in the processes of weathering and rock-water interaction of Morungaba granitoids belonging to Meridional Pluton (Valinhos Town-SP-Brazil). Specific activities of {sup 238}U, {sup 234}U, {sup 228}Ra and {sup 226}Ra were determined in non altered granitoids (Group A), as well as in those affected by different degrees of weathering (Groups B, C and D). The uranium specific activities were determined by alpha spectrometry method, whereas for the determination of radium isotopes high resolution gamma-ray spectrometry technique was employed. The data indicate that {sup 238}U and {sup 234}U are in radioactive equilibrium in the fresh analyzed granitoids, but show a slight depletion of {sup 234}U in relation to {sup 238}U in the weathered rocks. The ({sup 226}Ra/{sup 238}U) and ({sup 226}Ra/{sup 234}U) activity ratios of all investigated rocks are similar, showing a significant {sup 226}Ra depletion, which is probably caused by its preferential leaching. These results indicate that even samples macroscopically classified as fresh rocks, their systems have been opened for some geochemical changes. The high ({sup 234}U/{sup 238}U) activity ratios of groundwaters which are found in the fractures of these granitoids suggest their prolonged residence times in the aquifer and/or their percolation by other rocks presenting different geochemical properties.

    Radioactive liquid waste needs special attention and requires suitable treatment before deposition. Among the potential technologies under development for the treatment of liquid radioactive wastes the biosorption has been highlighted by being an efficient and low cost technique. Biosorption process involves the exchange of ions contained in the biomass matrix by others present in solution. There are many biomasses that could be applied in treatment of radioactive wastes, for example, agricultural residues and macrophyte. The aim of this study is evaluate the ability of the Azolla sp., a floating aquatic plant, to absorb uranium in solution. Azolla sp. is a macrophyte that has been used to treat effluents containing heavy metals. The biosorption capacity of uranium by Azolla sp. was experimentally determined and modeled by isotherms. Experiments were performed to determine metal uptake, and then the solutions were analyzed by inductively coupled plasma optical emission spectrometry (ICP-OES).

For each species, two incubations were prepared with ca. 300.0 mg of plant (DW and 1.0 L of reservoir water sample. The incubations were maintained in the dark and at 20 ºC. Periodically the dissolved oxygen (DO concentrations were measured; the accumulated DO values were fitted to 1st order kinetic model and the results showed that: i high oxygen consumption was observed for Ludwigia sp (533 mg g-1 DW, while the lowest was registered for Eleocharis sp1 (205 mg g-1 DW mineralisation; ii the higher deoxygenation rate constants were verified in the mineralisation of A. caroliniana (0.052 day-1, H. raniculoides (0.050 day-1 and U. foliosa (0.049 day-1. The oxygen consumption rate constants of Ludwigia sp and Eleocharis sp2 mineralisation (0.027 day-1 were the lowest. The half-time of oxygen consumption varied from 9 to 26 days. In the short term, the detritus of E. macrophyllus, H. raniculoides, Ludwigia sp, N. elegans and U. foliosa were the critical resources to the reservoir oxygen demand; while in the long term, A. caroliniana, H. multiflora and T. domingensis were the resources that can potentially contribute to the benthic oxygen demand of this reservoir.

    Abstract Rhodnius marabaensis sp. n. was collected on 12 May 2014 in the Murumurú Environmental Reserve in the city of Marabá, Pará State, Brazil. This study was based on previous consultation of morphological descriptions of 19 Rhodnius species and compared to the identification key for the genus Rhodnius. The examination included specimens from 18 Rhodnius species held in the Brazilian National and International Triatomine Taxonomy Reference Laboratory in the Oswaldo Cruz Institute in Rio de Janeiro, Brazil. The morphological characteristics of the head, thorax, abdomen, genitalia, and eggs have been determined. Rhodnius prolixus and Rhodnius robustus were examined in more detail because the BLAST analysis of a cyt-b sequence shows they are closely related to the new species, which also occurs in the northern region of Brazil. The most notable morphological features that distinguish Rhodnius marabaensis sp. n. are the keel-shaped apex of the head, the length of the second segment of the antennae, the shapes of the prosternum, mesosternum and metasternum, the set of spots on the abdomen, the male genitalia, the posterior and ventral surfaces of the external female genitalia, and the morphological characteristics of the eggs. Rhodnius jacundaensis Serra, Serra & Von Atzingen (1980) nomen nudum specimens deposited at the Maraba Cultural Center Foundation - MCCF were examined and considered as a synonym of Rhodnius marabaensis sp. n.

MÉTODOS: As observações foram feitas de outubro de 1996 a janeiro de 2000. Foram realizadas coletas sistemáticas de formas adultas mediante a utilização de isca humana, aspirações ambientais e armadilha tipo Shannon. A domiciliação foi estimada pelo índice de Nuorteva e pela razão de sinantropia. RESULTADOS: Foram feitas 87 coletas diurnas, com a obtenção de 872 adultos fêmeas. As médias de Williams', multiplicadas por 100, foram de 118 e 21 para Ae. albopictus nos horários de 7h às 18h e de 18h às 20h, respectivamente. Quanto a Ae. scapularis, foram de 100 e 106 nos mesmos períodos. Esse último revelou pico de atividade crepuscular vespertina. Na aspiração de abrigos, obteve-se o total de 1.124 espécimens, dos quais 226 Ae. albopictus e 898 Ae. scapularis. O período de janeiro a maio correspondeu ao de maior rendimento para ambos os mosquitos. Quanto à armadilha de Shannon, as coletas realizadas na mata revelaram a ausência de Ae. albopictus. No que concerne à domiciliação, esse último mostrou os maiores valores de índices, enquanto Ae. scapularis revelou comportamento de tipo ubiquista. CONCLUSÕES: Os resultados confirmam outras observações, permitindo levantar hipóteses. Em relação a Ae. scapularis, sugere-se que possa existir fenômeno de diapausa das fêmeas no período verão-outono, a qual cessaria no inverno-primavera quando então a atividade seria retomada. Quanto a Ae. albopictus, os dados sugerem que se trata de população em processo adaptativo ao novo ambiente.OBJECTIVE: Aedes albopictus and Ae. scapularis were found living together in the Pedrinhas Village, Southeastern of São Paulo State, Brazil.

    Full Text Available Honey from stingless bees (Melipona sp. is a nutritious and medicinal product economically valued in the informal Brazilian market, driven by the growing demand for natural products; however, its physicochemical characteristics are still unknown. Thus, the aim of this study is to evaluate the physicochemical profile of the stingless bee honey produced in Cruzeiro do Sul, Acre. Honey samples were analyzed following the methodology recommended by Ministério da Agricultura, Pecuária e Abastecimento; the following parameters were established: moisture, total sugars, reducing sugars, apparent sucrose, ash, crude protein, diastase activity, Brix degrees, free acidity, lactonic acidity, total acidity, pH, hydroxymethylfurfural, electrical conductivity, color and Lugol, Lund and Fiehe reactions. Results show that these parameters are not suitable for all samples, being incompatible with established standards, indicating that the current legislation on Apis mellifera is not suitable for all characters analyzed, mainly moisture content, corroborating the need to standardize guidelines for honey from stingless bees. Moreover, there was no tampering in the honeys analyzed.

    Cryptosporidium and Giardia are protozoans that can infect humans and wild and domestic animals. Due to the growing importance of diseases caused by protozoan parasites in aquatic species, we aimed to evaluate the frequency of infection by Cryptosporidium spp. and Giardia sp. in aquatic and marine mammals in the northern and northeastern regions of Brazil. We collected 553 fecal samples from 15 species of wild-ranging and captive aquatic mammals in northern and northeastern Brazil. All samples were analyzed by the Kinyoun technique for identification of Cryptosporidium spp. oocysts. Giardia sp. cysts were identified by means of the centrifugal-flotation technique in zinc sulfate solution. Subsequently, all samples were submitted for direct immunofluorescence testing. The overall frequency of infection was 15.55% (86/553) for Cryptosporidium spp. and 9.04% (50/553) for Giardia sp. The presence of Cryptosporidium spp. was detected in samples from 5 species: neotropical river otter Lontra longicaudis (15.28%), giant otter Pteronura brasiliensis (41.66%), Guiana dolphin Sotalia guianensis (9.67%), Amazonian manatee Trichechus inunguis (16.03%), and Antillean manatee T. manatus (13.79%). Giardia sp. was identified in L. longicaudis (9.23%), P. brasiliensis (29.16%), pygmy sperm whale Kogia breviceps (100%), dwarf sperm whale K. sima (25%), S. guianensis (9.67%), T. inunguis (3.81%), and T. manatus (10.34%). This is the first report of Cryptosporidium spp. in L. longicaudis, P. brasiliensis, and S. guianensis, while the occurrence of Giardia sp., in addition to the 2 otter species, was also identified in manatees, thus extending the number of hosts susceptible to these parasitic agents.

    Full Text Available Wood borer species of the families Euplatypodidae and Scolytidae were observed attacking trees of Pinus sp. in the Municipality of Ribas do Rio Pardo, state of Mato Grosso do Sul, Brazil, in March 2000. This plantation had been previously burned in an accidental fire in January 2000, causing the trees to become partially or totally unhealthy, rendering them more susceptible to attack of these pests. Galleries of these wood borers were opened with a chisel to observe parameters such as their direction and form of these galleries. Species observed as wood borers of Pinus sp. were Euplatypus parallelus, Euplatypus sp. (Coleoptera: Euplatypodidae and Xyleborus affinis (Coleoptera: Scolytidae.

    Full Text Available ABSTRACT We re-assess the taxonomic status of Owenia Delle Chiaje, 1841 from Southern Brazil based on estuarine specimens from Paranaguá Bay (Paraná and Babitonga Bay (Santa Catarina, and literature records. Owenia caissara sp. n. is diagnosed by a branchial crown with five pairs of tentacles, branched close to the base of the crown, rectilinear collar with a pronounced lateral slit, two ventrolateral ocelli partially covered by the collar, up to 23 hooks on a single row in the first abdominal segment, regularly curved nuchal shape, regularly moderate teeth curvature, and long and thin scales with oval transition. The description of Owenia caissara sp. n. reinforces the idea that Owenia fusiformis sensu lato is a complex of closely related species that can be distinguished on the basis of both macro- and micro- morphological traits.

    Full Text Available Abstract The mangrove oyster Crassostrea rhizophorae is an estuarine resource exploited by riverside communities in Northeast Brazil. Despite its socioeconomic importance, studies on the health status of this bivalve are scanty in this region. The purpose of the present study was to investigate the presence of the protozoan Perkinsus sp. in C. rhizophorae collected in August and September 2011 in three estuaries of the septentrional Northeast, Brazil: Jaguaribe (Ceará, Camurupim (Piauí and Carnaubeiras (Maranhão (n= 150 specimens/site. The samples were submitted to Ray’s fluid thioglycollate medium (RFTM, PCR and histology assays. The RFTM assay revealed spherical, blue or bluish-black hypnospores of the genus Perkinsus in 50 specimens (Jaguaribe= 17.3%, Camurupim= 5.3%, Carnaubeiras= 10.6%. The intensity of the infection ranged from very light (1-10 cells per slide to severe (more than 40 cells in each of 10 fields of the slide for Jaguaribe; very light for Camurupim and very light to moderate (at least 40 cells observed in each of 10 fields of the slide for Carnaubeiras. When submitted to confirmatory PCR analysis, 6 cases were confirmed (Jaguaribe=3, Camurupim=1, Carnaubeiras=2. The histology confirmed 21 cases of infection in specimens from the three estuaries. Although local collectors have reported no mortality in oyster populations that might be attributed to infection by Perkinsus, health surveillance of oyster populations in the septentrional region of Northeast Brazil is advisable.

    Full Text Available Some species of the genus Anastrepha (Diptera: Tephritidae are successfully managed by matching the sterile insect technique with parasitoid releases. Such strategies used in integrated pest management can be implemented only where insect mass-rearing programs are feasible. In this study, we show the process of domestication, rearing technology and quality control data obtained from 54 generations of Anastrepha sp.1 aff. fraterculus (Wiedemann, 1830 kept under fully artificial conditions. Eggs were collected by an artificial oviposition panel consisting of one side of the cage made of blue voile fabric externally covered with a thin layer of silicon rubber. They were then air-bubbled in water at 25 ºC for 48 h before seeding. Larvae were reared on the regular laboratory artificial diet with 66 % of agar reduction turning over a semi-liquid diet, which reduced costs and improved insect quality. The adult and larval diets were composed of local ingredients including hydrolyzed yeast. When large-scale production of this fly is contemplated, the critical stage is larval development. This system of artificial rearing for A. fraterculus sp.1 developed in Brazil, allows for the production of a large number of insects of excellent quality using local ingredients and less agar in diet composition than the original medium used for this species. By reducing the interval of egg collection, the system might be optimized in terms of insect yield and, therefore, meet the demands of A. fraterculus sp.1 with regard to integrated pest management purposes.

    Full Text Available Abstract Scuticociliatosis, which is caused by an opportunistic ciliate protozoan, is responsible for significant economic losses in marine ornamental fish. This study reports the occurrence of Uronema sp., which was found to be parasitizing three species of marine reef fish imported into Brazil and maintained in quarantine: Vanderbilt’s Chromis (Chromis vanderbilti, blue-green damselfish (Chromis viridis, and sea goldie (Pseudanthias squamipinnis. During the quarantine period, some fish presented with behavioral disorders and hemorrhages and ulcerative lesions on the body surface. Histopathological analysis showed hemorrhages, inflammation comprising mononuclear and granular cells in the skeletal muscle, and necrosis of the skin and the secondary lamellae of the gills, and parasites were also observed in the renal capsule. The absence of transboundary measures available to prevent the occurrence of ornamental fish diseases is also discussed.

    Full Text Available Neste artigo são analisados os fatores associados com o comportamento sexual e reprodutivo das adolescentes das regiões Nordeste e Sudeste do Brasil. A análise é implementada focando três dimensões deste processo: a iniciação sexual, o uso de métodos anticoncepcionais na primeira relação sexual e fecundidade. Modelos hierárquicos são implementados, pois adolescentes selecionadas de uma mesma comunidade devem ter comportamento sexual e reprodutivo mais semelhantes do que adolescentes selecionadas de áreas diferentes. O nível educacional da adolescente revelou-se o fator de risco mais importante nas três análises implementadas. Adolescentes com cinco ou mais anos de escolaridade são menos prováveis de ter a primeira relação sexual na adolescência; mais propensas a usar métodos anticoncepcionais nesta relação e apresentam menores riscos de ter filhos, quando comparadas com adolescentes com menos de cinco anos de escolaridade.This article calls attention to factors associated with sexual and reproductive behavior among adolescents from the Northeast and Southeast regions of Brazil. The analyses focus on three dimensions of this process: sexual initiation, use of contraceptives in the first sexual relationship, and fertility. Hierarchical models are implemented, because adolescents selected from the same community are more likely to have similar sexual and reproductive behavior than those from different communities. Level of schooling was the most important risk factor in the three analyses. Girls with 5 or more years of schooling were less likely to have their first sexual relationship during adolescence and more likely to use contraceptive methods in this relationship, besides demonstrating less risk of having children than their counterparts with less than 5 years of schooling.

Assim, o processo de preparação de massa via úmida pode ser uma alternativa para esta substituição, sendo necessária a obtenção de uma barbotina que apresente um comportamento reológico adequado ao processo e ao consumo de energia. Foram feitas medidas de viscosidade, tensão de cisalhamento e taxa de cisalhamento com viscosímetro rotacional, tendo como parâmetros de controle, o teor de sólidos da barbotina e a granulometria. Desta forma, foram verificadas variações das suspensões, como o comportamento pseudoplástico e a tixotropia. Também foi analisada a dependência do comportamento reológico com a mineralogia das argilas, obtida por difração de raios X. Os resultados das curvas reológicas mostraram-se muito coerentes com a mineralogia determinada, indicando uma piora do comportamento reológico no sentido da base para o topo da Formação Corumbataí, devido à alteração supérgena e presença de esmectitas.The study of rheological behavior of clay slips at Corumbataí Formation arose from the need for the ceramic industries of Santa Gertrudes pole (SP to adapt to the changes of the market behavior and to the demands of the environmental organs regarding the risks caused by the generation of dust in the mass preparation process.

    In this study it was assessed the occupational exposure to 222 Rn at IPEN, SP, Brazil, nuclear materials storage site through the committed effective dose received by workers exposed to this radionuclide. The radiation dose was calculated through the radon concentrations at nuclear materials storage site. Radon concentrations were determined by passive detection method with solid state nuclear detectors (SSNTD). The SSNTD used in this study was the polycarbonate Makrofol E; each detector is a small square plastic of 1 cm 2 , placed into a diffusion chamber type KFK. It was monitored 14 points at nuclear materials storage site and one external point, over a period of 21 months, changing the detectors every three months, from December 2004 to September 2006. The 222 Rn concentrations varied from 196 ± 9 and 2048 ± 81 Bq·m -3 . The committed effective dose due to radon inhalation at IPEN nuclear materials storage site was obtained from radon activity incorporated and dose conversion factor, according to International Commission on Radiological Protection procedures. The effective committed dose received by workers is below 20 mSv·y -1 . This value is suggested as an annual effective dose limit for occupational exposure by ICRP 60. (author)

    Full Text Available Observou-se o comportamento da população "Araraquara" de Anopheles darlingi, em seu ambiente original e em relação à sua atividade exófila com isca humana. As coletas foram realizadas às margens do rio Jacaré-Pepira, no Município de Dourado, Estado de São Paulo, Brasil. O ciclo nictemeral caracteriza-se pelo aspecto bimodal, com os dois picos correspondentes a cada crepúsculo, ou seja, vespertino e matutino. O seu detalhamento permitiu detectar bimodalidade secundária, subdividindo cada pico em um eocrepuscular precedendo ao intracrepuscular propriamente dito. A variação sazonal revelou aumento do número de mosquitos na estação chuvosa e quente e nítido declínio na seca e fria. Embora com dados insuficientes, houve indícios de que o An. albitarsis local, apresente também ritmo bimodal em seu ciclo diário de atividade.Fortnightly 25-hour catches, with human bait, were carried out in a modified environment of the "Jacaré-Pepira" River, Dourado County, S. Paulo, Brazil which is the original region of the "Araraquara" strain of Anopheles darlingi. The exophylic biting activity was mostly nocturnal with bimodal rhythm, showing two clear peaks corresponding, respectively, to dusk and dawn. Going into crepuscular details two secondary peaks were observed, an eocrepuscular preceding the intracrepuscular one As, by means of chromosome arrangement studies, this population was found to have low polymorphism, it is supposed that those rhythms are, in a good measure, of endogenous command. The number of mosquitoes biting increased during the hot, wet season and decreased remarkably during the dry, cold one. There was some evidence that An albitarsis may also show a bimodality in its nocturnal biting activity rhythm.

    Full Text Available Abstract Although sheep farming has grown in the state of Acre over the past four decades, little is known about occurrences of helminthiases in the herds of this region. The objective of the study was to assess the occurrences of non-intestinal helminthiasis among sheep slaughtered in Rio Branco. A total of 110 sheep livers were inspected from two slaughter batches (july 2014 and march 2015 in a slaughterhouse in Rio Branco. Livers with macroscopic lesions were photographed and were then subjected to histopathological analysis under an optical microscope. The macroscopic lesions showed small nodes with inflammatory characteristics and areas of fibrosis, which appeared to be calcified, thus suggesting a granulomatous reaction. Of the 110 evaluated livers, we noticed 110 nodules in total; these nodules have an average size of 0.5 cm. The histopathological analysis showed alterations to the architecture of the hepatic lobe, with multiple foci of necrosis and polymorphonuclear cells. Two samples revealed the presence of helminths from Nematode class and Capillaria sp. eggs identified by the typical morphology and morphometry. This seems to be the first report of Capillaria sp. in sheep livers in Brazil, and it serves as an important alert regarding animal health surveillance and control and regarding the Capillaria sp. zoonotic role in humans.

    Epistylis riograndensis n. sp., a freshwater peritrich hosting symbiotic algae in its cytoplasm, was collected from an artificial lake, in a Botanical garden in Southern Brazil. Its detailed morphology was investigated using live and silver-stained specimens. The colonial sessile E. riograndensis has elongate zooids measuring, on average, 162 μm in length and 45 μm in width. A single contractile vacuole located near the infundibulum and a C-shaped macronucleus located transversely in the adoral half of the cell were also observed. The oral infraciliature revealed in silver-stained specimens was typical of peritrich ciliates. Three infundibular polykineties consisting of 3 rows of kinetosomes were observed. Molecular analyses of 18s rDNA placed E. riograndensis among other Epistylis species in the Order Vorticellida.

    A project from 2013 to 2017 sought to discover pathogenic fungi and oomycetes from dipteran species that are vectors of major diseases of humans and animals in central Brazil and to begin evaluating the potential of these pathogens as potential biological control agents concentrated on mosquito larvae. Some collecting sites proved to be especially productive for pathogens of naturally occurring mosquito species and for placements of healthy sentinel larvae of Aedes aegypti in various sorts of containers in a gallery forest in the Santa Branca Ecoturismo Private Reserve of Natural Patrimony (RPPN) near Terezópolis de Goiás (GO). Collections during May-April of 2016 and February 2017 yielded a few dead mosquito larvae of an undetermined Onirion sp. (Culicidae: Sabethini) whose hemocoels contained many ovoid, thick-walled, yellow-golden to golden-brown, ovoid thick-walled resistant sporangia, 38.3±4×22.8±2.3µm, decorated by numerous, closely and randomly spaced punctations of variable size and shape. These were the first indisputable collections from Brazil of any Coelomomyces species. Comparisons of the morphology of these sporangia with those of other species of Coelomomyces, confirmed that this Brazilian fungus represented a new species that is described here as Coelomomyces santabrancae.

    Bats are ancient hosts of Trypanosoma species and their flying ability, longevity and adaptability to distinct environments indicate that they are efficient dispersers of parasites. Bats from Acre state (Amazon Biome) were collected in four expeditions conducted in an urban forest (Parque Zoobotânico) and one relatively more preserved area (Seringal Cahoeira) in Rio Branco and Xapuri municipalities. Trypanosoma sp. infection was detected by hemoculture and fresh blood examination. Isolated parasite species were identified by the similarity of the obtained DNA sequence from 18S rDNA polymerase chain reaction and reference strains. Overall, 367 bats from 23 genera and 32 species were examined. Chiropterofauna composition was specific to each municipality, although Artibeus sp. and Carollia sp. prevailed throughout. Trypanosoma sp. infection was detected in 85 bats (23·2%). The most widely distributed and prevalent genotypes were (in order) Trypanosoma cruzi TcI, T. cruzi marinkellei, Trypanosoma dionisii, T. cruzi TcIV and Trypanosoma rangeli. At least one still-undescribed Trypanosoma species was also detected in this study. The detection of T. cruzi TcI and TcIV (the ones associated with Chagas disease in Amazon biome) demonstrates the putative importance of these mammal hosts in the epidemiology of the disease in the Acre State.

    Full Text Available In Brazil, species of the genus Liriomyza are widely distributed and have economic importance as they cause damage to at least 14 plant families, especially Solanaceae, Cucurbitaceae, Asteraceae, and Fabaceae. Studies suggest existence of a species complex within this genus, based on the presence of morphological similarities among the species Liriomyza trifolii (Burgess, L. sativae Blanchard and L. huidobrensis (Blanchard. The present study aimed to use DNA barcoding to establish new distribution records of L. sativae in distinct regions in Brazil, determine intra- and inter-population genetic diversity, and reconstruct the phylogeny of Liriomyza species using the DNA barcode sequences. Identity values were between 97% and 99%, confirming that all the examined Brazilian populations belonged to the species L. sativae. Phylogenetic analyses indicated the presence of a single clade of L. sativae, composed of seven populations. Intra-population analysis on individuals of these populations indicated low levels of nucleotide and haplotype diversity. The haplotype network indicated presence of only 14 haplotypes distributed among the Brazilian populations. The genetic similarities shared by the Brazilian populations of L. sativae suggest that these populations are closely related. Genetic patterns observed among populations of L. sativae might be associated with bottleneck events or founder effect during establishment of this leafminer in Brazil.

    Full Text Available Abstract Bivalve culture is of considerable economic and social interest in northeastern (NE Brazil. The polyculture is an alternative approach to traditional monoculture for reducing the environmental impact of shrimp farming and improving oyster culture. Perkinsus marinus andPerkinsus olseni were found infecting oysters in NE Brazil and can threaten oyster production. This study evaluatedPerkinsus spp. occurrence in Crassostrea gasar during all production stages. Oyster spats were produced in a hatchery and grown in shrimp ponds in Rio Grande do Norte state.Perkinsus spp. were surveyed by Ray’s fluid thioglycollate medium and confirmed by polymerase chain reaction. Prevalence and intensity of infection were determined in oysters until they reached 7 cm. Results showed that the broodstock was already infected by Perkinsus (60%, but the derived spats were Perkinsus-free. Oyster spats acquired Perkinsus infection when transferred to ponds. The prevalence gradually increased in the seven months following placement in ponds (73%, and then decreased to 17% by the tenth month. The infections were initially mild, but intensity increased at the final growth stage. In conclusion, it is possible to produce Perkinsus-free C. gasar oyster spats from infected broodstock, and their culture in shrimp ponds is feasible.

    The aim of this study was to evaluate the species distribution, antibiotic-resistance profile and presence of enterotoxin (SE) genes in staphylococci isolated from the Dilúvio stream in South Brazil. Eighty-eight staphylococci were identified, 93.18% were identified as coagulase-negative (CNS) and 6.82% coagulase-positive (CPS). Fourteen Staphylococcus species were detected and the most frequently were Staphylococcus cohnii (30.48%) and S. haemolyticus (21.95%). Resistance to erythromycin was verified in 37.50% of the strains, followed by 27.27% to penicillin, 12.50% to clindamycin, 6.81% to trimethoprim-sulfamethoxazole, 5.68% to chloramphenicol and 2.27% to norfloxacin. None of the investigated strains showed gentamicin and ciprofloxacin resistance. The strains were tested for the presence of sea, seb, sec, sed and see genes by PCR and only CNS strains (43.18%) showed positive results to one or more SE genes. The scientific importance of our results is due to the lack of data about these topics in polluted waters in Brazil. In conclusion, polluted waters from the Dilúvio stream may constitute a reservoir for disseminating antibiotic-resistance and enterotoxin into the community. In addition, the detection of staphylococci in the polluted waters of the Dilúvio stream indicated a situation of environmental contamination and poor sanitation conditions.

    Local Climate Zones Classification to Urban Planning in the Mega city of São Paulo - SP, Brazil Tropical megacities have presented a strong trend in growing urban. Urban management in megacities has as one of the biggest challenges is the lack of integration of urban climate and urban planning to promote ecologically smart cities. Local Climatic Zones (LCZs) are considered as important and recognized tool for urban climate management. Classes are local in scale, climatic in nature, and zonal in representation. They can be understood as regions of uniform surface cover, structure, material and human activity that have to a unique climate response. As an initial tool to promote urban climate planning, LCZs represent a simple composition of different land coverages (buildings, vegetation, soils, rock, roads and water). LCZs are divided in 17 classes, they are based on surface cover (built fraction, soil moisture, albedo), surface structure (sky view factor, roughness height) and cultural activity (anthropogenic heat flux). The aim of this study is the application of the LCZs classification system in the megacity of São Paulo, Brazil. Located at a latitude of 23° 21' and longitude 46° 44' near to the Tropic of Capricorn, presenting humid subtropical climate (Cfa) with diversified topographies. The megacity of São Paulo currently concentrates 11.890.000 inhabitants is characterized by large urban conglomerates with impermeable surfaces and high verticalization, having as result high urban heat island intensity. The result indicates predominance in urban zones of Compact low-rise, Compact Mid-rise, Compact High-rise and Open Low-rise. Non-urban regions are mainly covered by dense vegetation and water. The LCZs classification system promotes significant advantages for climate sensitive urban planning in the megacity of São Paulo. They offers new perspectives to the management of temperature and urban ventilation and allows the formulation of urban planning

    The purpose of this research was to study the geochemical behavior of radionuclides and heavy metals in soils of agricultural use at Corumbatai River basin (SP). The natural concentration and variability in sedimentary rocks at Corumbatai river basin follow the trend Ca > Mg > K > Na, with the concentration of heavy metals and radionuclides. The distribution of exposure rate in soils shows the occurrence of higher values towards south of the Corumbatai river basin, region where are applied phosphate fertilizers, amendments and 'vinhaca' in sugar cane crops. Heavy metals and radionuclides incorporated in phosphate fertilizers and amendments are annually added during the fertilization process in the sugar cane crops, but if they are utilized in accordance with the recommended rate, they do not rise the concentration levels in soils up to hazards levels. Thus, they are lower transferred from soils to sugar cane at Corumbatai river basin, not offering hazard to the ecosystem and animal or human health. (author)

    The industry of leather manufacture generates large quantities of solid leather waste with characteristics of high-polluting and hazardous conditions. Among these wastes, stands out the wet blue leather (chromed leather scraps), and the tanning sludge and secondary sludge generated in the processes of effluents treatment. These wastes contain Cr(III), which, under oxidizing conditions, can turn into Cr (VI), which is highly toxic. However, these wastes are a potential source of chromium oxide (traditional industrial pigment), which could be used by the glass and ceramic enamel industries. In this study, a preliminary characterization of a chromium sludge from the industrial district of Franca-SP was conducted. X-ray diffraction (XRD), chemical (XRF) and thermal (DTA / TG) analyses were used to determine the physical and chemical characteristics of this solid waste. The potential of using this material as an available and cheap pigment for the manufacture of enamels and glass is discussed. (author)

    Full Text Available Diagnosis of the human cyclosporiasis is reported in São Paulo, SP, Brasil. Cyclospora cayetanensis has been identified in the feces of a patient by a modified Kinyoun staining method, with later sporulation in a solution of 2.5% potassium dichromate. The probability that this parasite is the eventual cause of gastrointestinal disturbances in the country was stimulated by this finding, which was arrived at by a simple technique. It had been kept in mind that the disease was expressing itself mainly among immunocompromised patients, whose number is increasing; especially in those with acquired immunodeficiency syndrome (AIDS, which is caused by the human immunodeficiency virus (HIV.É relatado o diagnóstico de ciclosporíase humana em São Paulo, SP, Brasil. Cyclospora cayetanensis foi encontrada nas fezes de um indivíduo através de exame pelo método de coloração de Kinyoun modificado, com posterior esporulação em dicromato de potássio a 2,5%. Esta verificação deve estimular a necessidade de considerar a ciclosporíase como eventual causa de distúrbios gastrointestinais no país, podendo ela ser reconhecida até mesmo por meio de técnica razoavelmente simples. Foi ainda lembrado que esta parasitose vem adquirindo expressividade sobretudo pelo fato de não raramente acometer imunodeprimidos, agora cada vez mais numerosos em especial como decorrência da infecção pelo vírus da imunodeficiência humana (HIV, que causa a síndrome da imunodeficiência adquirida (AIDS.

    16S rRNA gene sequence analysis of eight strains (BR 3299(T), BR 3296, BR 10192, BR 10193, BR 10194, BR 10195, BR 10196 and BR 10197) isolated from nodules of cowpea collected from a semi-arid region of Brazil showed 97 % similarity to sequences of recently described rhizobial species of the genus Microvirga. Phylogenetic analyses of four housekeeping genes (gyrB, recA, dnaK and rpoB), DNA-DNA relatedness and AFLP further indicated that these strains belong to a novel species within the genus Microvirga. Our data support the hypothesis that genes related to nitrogen fixation were obtained via horizontal gene transfer, as sequences of nifH genes were very similar to those found in members of the genera Rhizobium and Mesorhizobium, which are not immediate relatives of the genus Microvirga, as shown by 16S rRNA gene sequence analysis. Phenotypic traits, such as host range and carbon utilization, differentiate the novel strains from the most closely related species, Microvirga lotononidis, Microvirga zambiensis and Microvirga lupini. Therefore, these symbiotic nitrogen-fixing bacteria are proposed to be representatives of a novel species, for which the name Microvirga vignae sp. nov. is suggested. The type strain is BR3299(T) ( = HAMBI 3457(T)).

    Full Text Available The present study aimed to assess the quality and risks involved in the consumption of psychoactive herbal products (PHs that are available through informal commerce in the city of Diadema, SP, Brazil. Methods of ethnography were used to conduct the fieldwork during which four dealers were selected to record the collection, handling, packaging, types of PHs marketed, and their therapeutic purposes. In addition, lots of the PHs selected were purchased from the dealers and analyzed using microbiology and pharmacognosy techniques. 217 PHs were recorded and categorized into two main groups: stimulants (67% and depressants (27% of the central nervous system; sixteen of them were selected, and their 52 lots were acquired. The deficiencies observed in handling and packaging these lots by dealers were confirmed by microbiological analysis; 80.8% of them presented risk according to the indicators defined by the Brazilian Pharmacopoeia. The pharmacognostic analysis confirmed the authenticity of only 9 to 16 PHs analyzed. In addition, descriptions of contraindications, adverse reactions, and drug interactions were found in the literature for the PHs. The results of this study allow the observation of the priorities for the sanitary adequacy of the popular trade of herbs.

    The objectives of the study were to detect and genotype Cryptosporidium spp. and Giardia intestinalis in wastewater samples obtained from five cities with high transit of people in the State of São Paulo, Brazil, and at the entrance of a Wastewater Treatment Plant (WWTP) in Lima, Peru. Samples were collected and concentrated by centrifugation. The genomic DNA was extracted for molecular characterization by nested PCR for Cryptosporidium and double nested PCR for Giardia, followed by sequencing and phylogenetic analysis. G. intestinalis was found in 63.6 % of the samples, and the human assemblages A and B were identified. Cryptosporidium sp. was found in 36.4 % of the samples, and the species were corresponding to Cryptosporidium hominis, Cryptosporidium cuniculus, and Cryptosporidium muris. Results revealed the presence of human pathogenic Cryptosporidium species and G. intestinalis human pathogenic assemblages. Molecular tools highlight the importance to map the genetic diversity of these parasites, as well as to detect their epidemiological circulation pathway in the environment.

    The Radiological Protection Sector of the Sao Paulo Hospital/Federal University of Sao Paulo, SP, Brazil manages the records of 457 dosemeters. Once the users must know about the absorbed doses monthly and the need of keep the individuals records until the age of 75 years old and for, at least during 30 years after the end of the occupation of the individual, it became necessary to construct a database and a computerized control to manage the accumulated doses. This control, between 1991 and 1999, was effected by means of a relational database (Cobol 85 - Operating System GCOS 7 (ABC Telematic Bull)). After this period, when the company responsible for dosimetry went on to provide computerized results, the data were stored in a Paradox database (Borland). In 2004, the databases were integrated and were created a third database developed in Oracle (IBM) and a system that allowed the institutional Intranet users to consult their accumulated doses annually and the value of the total effective dose accumulated during working life

    Abstract A new species of troglobitic harvestman, Iandumoema smeagol sp. n., is described from Toca do Geraldo, Monjolos municipality, Minas Gerais state, Brazil. Iandumoema smeagol sp. n. is distinguished from the other two species of the genus by four exclusive characteristics – dorsal scutum areas with conspicuous tubercles, enlarged retrolateral spiniform tubercle on the distal third of femur IV, eyes absent and the penial ventral process slender and of approximately the same length of the stylus. The species is the most highly modified in the genus and its distribution is restricted only to caves in that particular area of Minas Gerais state. The type locality is not inside a legally protected area, and there are anthropogenic impacts in its surroundings. Therefore, Iandumoema smeagol sp. n. is vulnerable and it must be considered in future conservation projects. PMID:26798238

    Full Text Available O estudo da variação temporal de chuvas intensas é de grande importância na hidrologia, para a análise e previsão de eventos extremos, necessárias em projetos de controle de engenharia. Com esse objetivo, foram analisados dados de pluviogramas da cidade de Piracicaba, SP, do período de 1966 a 2000, para se determinar a distribuição temporal de chuvas intensas de 60 e de 120 min de duração. As chuvas de 60 min foram subdivididas em três intervalos iguais e sucessivos de 20 min cada um, enquanto as chuvas de 120 min foram subdivididas em quatro intervalos iguais e sucessivos de 30 min cada um. O modelo de distribuição da precipitação que predominou para as chuvas de 60 e 120 min, foi do tipo exponencial negativo, com 85,7 e 50,7% dos casos, respectivamente. Para as chuvas de 60 min, com altura pluviométrica média de 20,7 mm, a distribuição foi de 72,3, 21,4 e 6,2% do total precipitado, respectivamente, nos três intervalos sucessivos de 20 min. Para as chuvas de 120 min, com altura pluviométrica média de 33,3 mm, o resultado foi de 60,1, 25,2, 11,1 e 3,6%, respectivamente, nos quatro intervalos sucessivos de 30 min. O modelo de distribuição temporal dessas chuvas não foi modificado pelo total precipitado nem pela sua duração, nos intervalos em questão.Time distribution models of intense and short rains are very important in hydrology and for extreme predictions in engineering projects. With this purpose, rain data of Piracicaba, SP, Brazil, from 1966 to 2000 were analyzed to establish time distribution models of 60 and 120 min intense rains, during the rainy season from October through March. Time distribution models were assessed by three intervals of twenty minutes duration, for 60 min rains and by four intervals of thirty minutes duration for 120 min rains. The prevailing precipitation model for both, 60 and 120 min rains was a negative exponential distribution, in 85.7 and 50.7% of cases, respectively. For 60 min

    Air pollution is an important problem for São Paulo city and vehicles are the main source. About 11 million people are exposed to this pollution. To examine studies realized about air pollution and its effects on health of the population of São Paulo (Brazil) and methods of assessing exposure to pollution related to traffic. We performed a literature review using the keywords "air pollution", "São Paulo", and traffic-related air pollution. As results were obtained several studies that found relation between air pollution in São Paulo and respiratory and cardiovascular problems, fetal growth, increased mortality and hospitalizations, particularly in children and elderly people. In order to estimate the exposure, most of these studies consider the isotropic distribution of pollutants throughout the area, what prevents the evaluation of and the influence of traffic. Several methods have been used to analyze the air traffic exposure, which can be used isolated or combined. It is believed that the combination of models used to calculate pollutant concentrations to methods of georeferencing is the most appropriate approach for similar studies in São Paulo. The advantages of these methods are the ability to identify priority areas and situations, obtaining detailed information for adoption of public policies or measures, and to simulate different scenarios. The application of these methods in studies at São Paulo depends on the improvement of input data, air quality meteorological monitoring net enhancement and data of traffic volume.

    With the advent of techniques that enabled the detection of radioactivity, a new frontier was opened in the many areas of Earth sciences, as the radionuclides can be used as tracers for processes of physical, chemical and biological natures. In this context, natural ( 40 K, 232 Th and 238 U) and artificial ( 137 Cs) radionuclides were measured through the means of high-resolution gamma spectrometry, a non-destructive technique, in the Cananeia-Iguape Estuarine Complex (Sao Paulo, Brazil). The activities obtained are 107.61 - 573.84 Bq kg -1 for 40 K, 11.11 - 73.65 Bq kg -1 for 232 Th, 2.27 - 60.76 Bq kg -1 for 238 U, and 0.23 - 3.49 Bq kg -1 for 137 Cs, with 137 Cs content within the observed range for samples environmentally affected only by the fallout of past nuclear tests. Also, these radionuclides presented a significant (α = 0.05) correlation with grain size distribution and organic carbon content as well. (author)

    Universities and research centers that use stable isotopes follow a worldwide trend in owning laboratories isotope ratio that serves multiple users, as well as minimize maintenance costs, operation and staff training. For this purpose it was created in 1998, the Center Stable Isotopes 'Centro de Isotopos Estaveis' - CIE, which is an auxiliary unit linked to the Institute of Biosciences (IB) of the Sao Paulo State University - UNESP Botucatu Campus, Brazil. The best way to CIE grow and achieve excellence are already disclose the methodologies employed and practice areas consolidated to find new partnerships with different applications, and also seek new methods of analysis that can expand areas. The aim of this study is to disseminate methodologies for analysis of isotope ratio and areas of the CIE. The CIE analyzes the isotopic ratios 13 C/ 12 C, 15 N/ 14 N, 2 H/ 1 H and 18 O/ 16 O (CHON), and for the carbon samples can be solid, liquid and gas (in the form of CO 2 ) for the other elements is only possible to analyze in solid or liquid form. All samples are always analyzed separately by the destructive method. The CIE addition to performing scientific partnerships with all university, complementary and auxiliaries units of UNESP Botucatu campus also have partnerships in other academic units on campus of UNESP Jaboticabal and Dracena and Sao Paulo University in Piracicaba campus and is open to new partnerships in other research units.

    Full Text Available The quality control of drugs has an important role in public health, in ensuring the efficacy and safety of medicines. In the public health system, compounding pharmacies play a vital part. They provide medicines tailored to the individual patient, for example dermatological products and specific doses for children. Unfortunately, many cases of compounded products falling below the minimum quality standard have been reported in Brazil. In this study, the quality of compounded 150 mg fluconazole capsules was assessed and the results were compared with values stipulated in the Brazilian pharmacopoeia. The results suggest that, while it is certainly possible to prepare products meeting pharmacopoeial specifications, there are pharmacies where the quality control is deficient or nonexistent. Fluconazole is an important drug in combatting fungal infections. The use of fluconazole in dosage forms manufactured without high standards of quality control is strongly linked to treatment failure and cases of intoxication, as well as the emergence of resistant microorganisms. This highlights the urgent need for process improvement in compounding pharmacies. There are validated methods that can be successfully employed for routine quality control analysis that can be implemented by any compounding pharmacy.

  1. The importance of protozoan bacterivory in a subtropical environment (Lobo-Broa Reservoir, SP, Brazil

    Full Text Available This study evaluated the importance of heterotrophic nanoflagellates (HNF and ciliates bacterivory in a mesotrophic subtropical environment (Lobo-Broa Reservoir, Brazil by the quantification of their ingestion rates. The in situ experiments using fluorescently labelled bacteria (FLB were carried out bimonthly over one year (three surveys in the dry season and three in the rainy one at the sub-surface of two sampling points that have different trophic degrees. The ingestion rates for both ciliates and HNF were higher in the meso-eutrophic region (point 2 due to the higher water temperatures, which accelerate the metabolism of protozoans and the higher bacteria densities. Concerning total protozoan bacterivory, the HNF had the greatest grazing impact on bacterial community, especially the HNF <5µm. The data showed that HNF grazing, in addition to regulating the bacteria abundance, also induced changes to the bacterial community structure, such as increasing size and numbers of bacterial filaments. The ciliates were also important to the system bacterivory, especially in point 2, where there were high densities and ingestion rates. The protozoan bottom-up control was more important in the dry season and the top-down control was more important in the rainy season, so, these two forces are equally important to the bacterial abundance regulation in this reservoir in an annual basis.

    The objective of the present work is to determine 210 Po activity concentration in estuarine sediments from Baixada Santista. The area comprehends nine cities in the Brazilian coast (Bertioga, Guaruja, Santos, Sao Vicente, Cubatao, Praia Grande, Mongagua, Itanhaem and Peruibe). It is one of the most important industrial areas in Brazil due to the large number of industries operating in Cubatao, such as steel, petrochemical and fertilizer industries. That, together with a large population, causes a negative impact on marine biota. The cores were obtained from Sao Vicente and Bertioga by extracting profiles up to 1 meter depth with a Piston core sampler. The samples were prepared and treated with both physical and chemical processes. The physical processes include drying, grinding and sieving. The chemical preparation consists of a series of acid digestion till total dissolution and destruction of organic matter. After the acid digestion, the samples were filtered and evaporated till dryness. The residue was then dissolved in HCl 6.25 M. Po was spontaneously deposited in mirror finished silver disc, for 2 hours at 90 deg C and constant agitation. The disc was then counted in a surface barrier alpha detector for 200,000 seconds. Three cores were analyzed so far, two from Sao Vicente and one from Bertioga. (author)

    The Radiotoxicology Laboratory (LRT) of IPEN/CNEN-SP has as mission to assess internal internal contamination from individuals through qualitative and quantitative analysis of radionuclides present in biological samples. The LRT is able to meet the demand for in vitro monitoring and radiological and nuclear emergencies, both in the case of occupational exposures, as individuals. With the purpose of increasing the reliability of the test results, and keeping it up to date on new analytical techniques, the LRT participates annually in two laboratory inter-comparison programs: a national, the PNI (Programa Nacional de Intercomparacao), promoted by IRD/CNEN and an international from PROCORAD (Association for the Promotion of Quality Controls in Radiotoxicological Bioassay). The present work shows the performance of the LRT by means of the results obtained in the exercises for the quantification of natural uranium and uranium isotopes, promoted by both the inter-comparison programs in the year of 2004. The analysis of the obtained results demonstrates the good performance achieved by LRT, and confirms the sustainability of its quality system, required in calibration and testing laboratories

    In the work reported in this dissertation, a facility for neutron tomography was developed and installed at the irradiation channel 14 of the IEA-R1 nuclear research reactor of IPEN-CNEN/SP. Several selected objects were inspected, and the obtained images demonstrate the main characteristic of the present technique that is its capability to visualize hydrogenous rich substances. In such facility, a tomography can be obtained in 400 s with a spatial resolution of 205 μm, and the obtained images have sufficient quality to allow qualitative and quantitative analysis. These characteristics are very similar to the ones of the top facilities around the world, and the quality of the provided images are sufficient to allow qualitative and quantitative analysis of the inspected object. The implementation of the neutron tomography technique opens up the possibility of new research as it provides a new tool for inspection of objects, which provides a view of its internal structure, which is not always possible for two-dimensional imaging methods.

    Full Text Available Within the scope of the MAR-14 Project, part of the Brazil-Germany Bilateral Agreement in Marine Sciences, an oceanographic survey aboard the R/V Victor Hensen was carried out in Brazilian coastal waters between Santos (23º56'S and Rio de Janeiro (22º54'S, from January 15 to January 22,1991. In this article we report results of preliminary analyses of the hydrographic data collected with CTD, STD, Nansen bottles and XBT's. These preliminary results show intense stratification in the first 200 m depth, and the penetration of the Brazil Current deep into the continental shelf region. Two eddy-like features were detected. The first one, anticyclonic, was located in the northern part of the domain and confined to the uppermost 200 m. The second, a cyclonic vortex, was found a little to the southwest below 200 m and extending downwards to about 800 m depth. Water mass analyses based on T-S diagrams suggest that the interface between the South Atlantic Central Water (SACW and the Antarctic Intermediate Water (AIW is located at about 500 m depth. One important aspect of this study is that this was the first time a high resolution survey with a CTD probe was realized along the eastern Brasilian Coast, south of Cabo Frio.Como parte do projeto MAR-14, componente do Acordo Bilateral Brasil-Alemanha em Ciências Marinhas, uma campanha oceanógrafica a bordo do R/V Victor Hensen foi realizada em águas costeiras do Brasil entre Santos (23º56'S, de 15 a 22 de janeiro de 991.

    Carbapenems resistance in Enterobacter spp. has increased in the last decade, few studies, however, described the mechanisms of resistance in this bacterium. This study evaluated clonality and mechanisms of carbapenems resistance in clinical isolates of Enterobacter spp. identified in three hospitals in Brazil (Hospital A, B and C) over 7-year. Antibiotics sensitivity, pulsed-field gel electrophoresis (PFGE), PCR for carbapenemase and efflux pump genes were performed for all carbapenems-resistant isolates. Outer-membrane protein (OMP) was evaluated based on PFGE profile. A total of 130 isolates of Enterobacter spp were analyzed, 44/105 (41, 9%) E. aerogenes and 8/25 (32,0%) E. cloacae were resistant to carbapenems. All isolates were susceptible to fosfomycin, polymyxin B and tigecycline. KPC was present in 88.6% of E. aerogenes and in all E. cloacae resistant to carbapenems. The carbapenems-resistant E. aerogenes identified in hospital A belonged to six clones, however, a predominant clone was identified in this hospital over the study period. There is a predominant clone in Hospital B and Hospital C as well. The mechanisms of resistance to carbapenems differ among subtypes. Most of the isolates co-harbored blaKPC, blaTEM and /or blaCTX associated with decreased or lost of 35-36KDa and or 39 KDa OMP. The efflux pump AcrAB-TolC gene was only identified in carbapenems-resistant E. cloacae. There was a predominant clone in each hospital suggesting that cross-transmission of carbapenems-resistant Enterobacter spp. was frequent. The isolates presented multiple mechanisms of resistance to carbapenems including OMP alteration.

    Pb-210 (T{sub 1/2} = 22.3 y), a natural radionuclide from U-238 serie can be found in the atmosphere, as a product of {sup 222}Rn decay that emanates from the ground, where its atoms become rapidly fixed to aerosols and return to the earth as dry fallout or are washed out in the rain. This natural radionuclide has been widely used as an atmospheric tracer, to determine the aerosol residence time as well as chronometers in the environment. Pb-210 was measured during a period of two years, 2011 to 2013, in samples of rainfall in all the rainy events that occurred at the Instituto de Pesquisas Energeticas e Nucleares (IPEN) campus (23 deg 33’59.24” S - 46 deg 44’15.63” O at 760 m above sea level) which is located in the city of Sao Paulo, in the state of Sao Paulo, Brazil. Pb-210 concentration was measured in a total of 123 rainy events by beta gross counting in a low background gas flow proportional detector, after radiochemistry procedure. The results obtained were correlated to seasons and rainfall. The concentrations of {sup 210}Pb in rainfall varied from the minimum detectable activity, 4.9 mBq L{sup -1} to 1408± 43 mBq L{sup -1}. The highest concentrations were obtained in the months of winter and the lowest in summer. The monthly depositional flux of {sup 210}Pb, varied from 4.03 Bq m{sup -2} month{sup -1} to 46.4 Bq m{sup -2} month{sup -1}presenting a strong correlation with the amount of precipitation and hence showing seasonal trends.

    Giardia and Cryptosporidium have caused several outbreaks of gastroenteritis in humans associated with drinking water. Contaminated sewage effluents are recognized as a potential source of waterborne protozoa. Due to the lack of studies about the occurrence of these parasites in sewage samples in Brazil, we compared the efficiency of two procedures for concentrating cysts and oocysts in activated sludge samples of one sewage treatment plant. For this, the samples were submitted to i) concentration by the ether clarification procedure (ECP) and to ii) purification by sucrose flotation method (SFM) and aliquots of the pellets were examined by immunofluorescence. Giardia cysts were present in all samples (100.0%; n = 8) when using ECP and kit 1 reagents, while kit 2 resulted in six positive samples (85.7%; n = 7). As for SFM, cysts were detected in 75.0% and 100.0% of these samples (for kit 1 and 2, respectively). Regarding Cryptosporidium, two samples (25.0%; kit 1 and 28.5% for kit 2) were detected positive by using ECP, while for SFM, only one sample (examined by kit 1) was positive (12.5%). The results of the control trial revealed Giardia and Cryptosporidium recovery efficiency rates for ECP of 54.5% and 9.6%, while SFM was 10.5% and 3.2%, respectively. Considering the high concentration detected, a previous evaluation of the activated sludge before its application in agriculture is recommended and with some improvement, ECP would be an appropriate simple technique for protozoa detection in sewage samples.

    Full Text Available INTRODUCTION: The lack of basic knowledge on venomous arthropods and the benignity of the clinical manifestations contribute to the centipede bite victims' not being taken to a treatment reference center, leading to underestimation of the number of cases and minimizing the possibility of a broader epidemiological view. An inventory of the centipede bite occurrences in Greater S. Paulo, Brazil, and the therapeutic methods employed, by the main Brazilian medical center for the notification of poisoning by venomous animals, is presented. METHOD: All patient cards of the period 1980-1989 have been checked as to place, month and time of occurrence; sex, age, affected part of the body, signs and symptoms have been observed, as well as the therapeutic methods employed. The centipedes that caused the accidents were identified at the Arthropods Laboratory. RESULTS: It was registered 216 accidents, with a 69% predominance of the Greater S. Paulo and in only 63% of the cases (136 was the agent brought in by the victim for identification. The genera most frequently represented were Cryptops (58%, Otostigmus (33% and Scolopendra (4%. Of the 136 cases, 87% showed erythema, edema, hemorrhage, burns, cephalalgia, and intense pain. There was a predominance of accidents in the warm rainy season, in the morning and for females between 21 and 60 years of age. Hands and feet were the parts of the body most affected. The benign evolution of the clinical picture (54% made therapeutical treatment unnecessary. Only the victims of Scolopendra and Otostigmus (46% were medicated with anesthetics (51%, analgesics (25%, antihistamines and cortisone (24%. CONCLUSION: The reproductive period of the centipedes, associated with their sinanthropic habits, contributes to the greater incidence of accidents in urban areas in the warm rainy season. Only patients bitten by Scolopendra and Otostigmus require therapeutical treatment.

    IPEN's fuel cycle activities were accomplished in laboratory and pilot plant scale and most facilities were built in the 70-80 years. Nevertheless, radical changes of the Brazilian nuclear policy in the beginning of 90's determined the interruption of several fuel cycle activities and facilities shutdown. Since then, IPEN has faced the problem of the pilot plants decommissioning considering that there was no experience/expertise in this field at all. In spite of this, some laboratory and pilot plant decommissioning activities have been performed in IPEN in the last years, even without previous experience and training support. One of the first decommissioning activities accomplished in IPEN involved the Hot Chemistry Laboratory. This facility was built in the beginning of the 80's with the proposal of supporting research and development in the nuclear chemistry area. It was decided to settle a new laboratory in the place where the Hot Chemistry Laboratory was installed, being necessary its total releasing from the radioactive contamination point of view. The previous work in the laboratory involved the manipulation of samples of irradiated nuclear fuel, besides plutonium-239 and uranium-233 standard solutions. There were 5 glove-boxes in the facility but only 3 were used with radioactive material. The glove-boxes contained several devices and materials, besides the radioactive compounds, such as: electric and electronic equipment, metallic and plastic pieces, chemical reagents, liquid and solid radioactive wastes, etc. The laboratory's decommissioning process was divided in 12 steps. This paper describes the procedures, problems faced and results related to the Hot Chemistry Laboratory decommissioning operations and its reintegration as a new laboratory of the Chemical and Environmental Technology Center (CQMA) - IPEN-CNEN/SP.

    Full Text Available This study describes how the foraging activity of Melipona rufiventris is influenced by the environment and/or by the state of a colony. Two colonies were studied in Ubatuba, SP (44° 48’ W and 23° 22’ S from July/2000 to June/2001. These colonies were classified as strong (Colony 1 and intermediate (Colony 2 according to their general conditions: population and brood comb size and number of food pots. The bees were active from dawn to dusk. The number of pollen loads presented a positive correlation with relative humidity (r s = 0.401; p <0.01 and was highest between 70 and 90%. However, it was negatively correlated with temperature (r s = -0.228; p <0.01 showing a peak between 18 and 23 °C. The number of nectar loads presented a positive correlation with temperature (r s = 0.244; p <0.01 and light intensity (r s = 0.414; p <0.01; it was greater between 50 and 90% of relative humidity and 20 and 30 °C of temperature. They collected more nectar than pollen throughout the day, and were more active between 6 and 9 hours. Workers from Colony 1 (strong collected nectar in greater amounts and earlier than those from Colony 2 (intermediate. The number of pollen, nectar and resin loads varied considerably between the study days. Peaks of pollen collection occurred earlier in months with longer days and in a hotter and more humid climate. The foraging behavior of M. rufiventris is probably affected by the state of the colony and by environmental conditions, notably temperature, relative humidity, light intensity and length of the day.

    Full Text Available This research evaluated the physicochemical parameters of a leachate sample from a controlled landfill in the city of Guaratinguetá-SP. The evaluation was conducted using spectrometric and spectrophotometric methods in order to assess the formation of persistent compounds. The selection of parameters was based on the CETESB Article 18 and CONAMA 357/05 Article 34, as well as organic characterization methods, such as FTIR, NMR (1H-NMR, 13C-NMR and APT, GC-MS, molar mass distribution and elemental analysis (CHN. Chemical and physical stability were also verified. The ammoniacal nitrogen concentration is 20 times greater than tolerance limit established by law (20 mg L-1. The Ba and Ni presented concentrations above those permitted by the legislation (CETESB Article 18 and CONAMA 357/05 Article 34. Those values of chemical oxygen demand (COD and total organic carbon (TOC were 1013 mg L-1 and 286 mg L-1, respectively. It was not possible to determine the biochemical oxygen demand (BOD of slurry sample.

    The Guarapiranga Reservoir, located in Sao Paulo metropolitan region, Brazil, is responsible for supplying about 20% of the entire population's water needs of this region or approximately 3.7 million people. However, this system has shown significant degradation in water quality, due to untreated domestic sewage and industrial effluents. In this study sediment samples were collected at five points along the reservoir and total concentration of some major (Fe, K and Na), trace (As, Ba, Br, Co, Cr, Cs, Hf, Hg, Rb, Sb, Sc, Ta, Tb, Th, U, V and Zn) and rare earth (Ce, Eu, La, Lu, Nd, Sm, Tb and Yb) elements were determined by instrumental neutron activation analysis (INAA). By inductively coupled plasma optical emission spectrometry (ICP OES) the concentrations of Al, Ba, Be, Ca, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, Pb, Ti, V e Zn were determined after digestion procedure following US EPA 3051 methodology. The concentrations of metals Cd and Pb were determined by graphite furnace atomic absorption spectrometry (GFAAS) and total Hg by cold vapor atomic absorption spectrometry (CVAAS). Methodology validation according to precision and accuracy was performed by reference materials analyses for the three different analytical techniques used. Multielemental results obtained by INAA were compared to NASC (North American Shale Composite), Upper Continental Crust (UCC) and soil from Guarapiranga park values. The Enrichment Factor (EF) and Geo accumulation Index (Igeo) were also evaluated for these data. Metal concentration results by ICP OES and AAS in the samples were compared to the TEL and PEL oriented values established by the Canadian Council of Ministers of the Environment and also adopted by CETESB (Environmental Protection Agency of the Sao Paulo State). The results were also compared to regional reference values (VRR) of limnic sediments from the Alto Tiete Basin. From these data an assessment of metal and trace element accumulated in the sediments from the

    Perkinsus genus includes protozoan parasites of marine mollusks, especially bivalves. In the last four years, this parasite has been detected in mangrove oysters Crassostrea rhizophorae and Crassostrea gasar from the Northeastern region of Brazil. Hemocytes are the key cells of the oyster immune system, being responsible for a variety of cellular and humoral reactions, such as phagocytosis, encapsulation and the release of several effector molecules that control the invasion and proliferation of microorganisms. In Brazil, there is little information on perkinsosis and none on the immune responses of native oysters' species against Perkinsus spp. The objective of this study was to determine the effects of natural infection by Perkinsus sp. on the immunological parameters of mangrove oysters C. gasar cultured in the Mamanguape River Estuary (Paraíba, Brazil). Adults oysters (N = 40/month) were sampled in December 2011, March, May, August and October 2012. Gills were removed and used to determine the presence and intensity of the Perkinsus sp. infection, according to a scale of four levels (1-4), using the Ray's fluid thioglycollate medium assay. Immunological parameters were measured in hemolymph samples by flow cytometry, including: total hemocyte count (THC), differential hemocyte count (DHC), cell mortality, phagocytic capacity, and production of Reactive Oxygen Species (ROS). The plasma was used to determine the hemagglutination activity. The results showed the occurrence of Perkinsus sp. with the highest mean prevalence (93.3%) seen so far in oyster populations in Brazil. Despite that, no oyster mortality was associated. In contrast, we observed an increase in hemocyte mortality and a suppression of two of the main defense mechanisms, phagocytosis and ROS production in infected oysters. The increase in the percentage of blast-like cells on the hemolymph, and the increase in THC in oysters heavily infected (at the maximum intensity, 4) suggest an induction of

    This paper describes light and ultrastructural observations and molecular analysis of a fish-infecting myxosporean, Henneguya gilbert n. sp., which was found infecting the gill epithelium of the commercially important freshwater teleost fish Cyphocharax gilbert (Curimatidae) collected in the estuarine region of Guandu River, Rio de Janeiro State, Brazil. The parasite occurs in the gills, forming whitish spherical to ellipsoidal polysporic cysts measuring up to ~ 750 μm, and displaying asynchronous development. Mature myxospores are ellipsoidal with a bifurcated caudal process. The length, width and thickness of the body of the myxospore are 12.0 × 5.3 × 3.6 μm, respectively; two equal caudal processes are 16.8 μm long, and the total length of the myxospore is 27.2 μm. There are two unequal polar capsules: the larger measures 5.5 μm length × 1.3 μm width and has a polar filament with 9-10 coils; the smaller is 4.0 μm long × 1.3 μm wide and has a polar filament with 7-8 coils. The sporoplasm is binucleated and presents a spherical vacuole surrounded by numerous globular sporoplasmosomes. Phylogenetic analysis, based on the small subunit rRNA sequencing, using maximum likelihood method reveals the parasite clustering together with other myxobolids that are histozoic and parasitize freshwater fish of the order Characiformes, thereby strengthening the contention that the host phylogenetic relationships and aquatic environment are the strongest evolutionary signals for myxosporeans of the family Myxobolidae.

    Root nodule bacteria were isolated from nodules on Mimosa pudica L. growing in neutral-alkaline soils from the Distrito Federal in central Brazil. The 16S rRNA gene sequence analysis of 10 strains placed them into the genus Rhizobium with the closest neighbouring species (each with 99 % similarity) being Rhizobium grahamii, Rhizobium cauense, Rhizobium mesoamericanum and Rhizobium tibeticum. This high similarity, however, was not confirmed by multi-locus sequence analysis (MLSA) using three housekeeping genes (recA, glnII and rpoB), which revealed R. mesoamericanum CCGE 501T to be the closest type strain (92 % sequence similarity or less). Chemotaxonomic data, including fatty acid profiles [with majority being C19 : 0 cyclo ω8c and summed feature 8 (C18 : 1ω7c/C18 : 1ω6c)], DNA G+C content (57.6 mol%), and carbon compound utilization patterns supported the placement of the novel strains in the genus Rhizobium. Results of average nucleotide identity (ANI) differentiated the novel strains from the closest species of the genus Rhizobium, R. mesoamericanum, R. grahamii and R. tibeticum with 89.0, 88.1 and 87.8 % similarity, respectively. The symbiotic genes essential for nodulation (nodC) and nitrogen fixation (nifH) were most similar (99-100 %) to those of R. mesoamericanum, another Mimosa-nodulating species. Based on the current data, these 10 strains represent a novel species of the genus Rhizobium for which the name Rhizobium altiplani sp. nov. is proposed. The type strain is BR 10423T (=HAMBI 3664T).

Os grupos de N. leporinus observados permaneceram em atividade ao longo de todo o período noturno, mas com um aparente padrão bimodal. Durante os meses de abril a setembro, N. leporinus inicia a sua atividade geralmente às 18:00 h, uma hora mais cedo do que durante os meses de outubro a março, quando inicia sua atividade geralmente às 19:00 h. O comportamento de predação sobre os cardumes de peixes mostrou variações quanto ao local de forrageamento ao longo do período de atividade. Em baixos níveis de maré, os grupos de morcegos pescaram longe da margem em águas mais profundas, mas nos níveis de maré alta os grupos de morcegos permaneceram pescando sempre junto à margem, em águas mais rasas. Este padrão de comportamento em N. leporinus parece ser determinado pelo padrão de deslocamento dos cardumes de peixes na área de estudo.From January 18 to December 16 of 1999 the foraging behavior and activity pattern of fishing bat Noctilio leporinus (Linnaeus, 1758 were studied in mangrove ecosystem of Guaratuba Bay, southern Brazil.

During April and September N. leporinus generally begin their activity at 18:00h, one hour earlier than October to March months, when their activity started at 19:00 h. The foraging behavior on fish shoal varied spatially along all the activity period. During low tide level the bat groups remained fishing distant from margin on deeper water, but during high tide level the bats were always observed fishing close to the margin on flat water. This pattern in foraging behavior of N. leporinus appears to be determined by the fish shoal displacement pattern in

O objetivo do estudo foi analisar a distribuição sazonal e vertical desses anofelinos, visando contribuir para a avaliação do risco de transmissão desse agravo. MÉTODOS: No município de Ilha Comprida, SP, foram instaladas armadilhas luminosas tipo CDC iscadas com gelo seco, das 17 às 20h, a um, seis e 12m do solo, quinzenalmente, de setembro de 2001 a setembro de 2002. A relação da densidade desses anofelinos com o clima foi avaliada pelo coeficiente de Spearman e suas densidades entre os estratos foram comparadas pelo teste não paramétrico de Mann-Whitney. RESULTADOS: Do total de 55.226 mosquitos, 1.341 eram An. bellator (2,4% do total de Culicidae, sendo capturados 278 indivíduos próximo ao solo, 261 a seis metros e 802 na copa (12 m.

    In 2010, a novel spotted fever group rickettsiosis was reported in the Atlantic rainforest coast of Brazil. The etiological agent was identified as Rickettsia sp. strain Atlantic rainforest, and the tick Amblyomma ovale was incriminated as the presumed vector. The present study evaluated under laboratory conditions four colonies of A. ovale: two started from engorged females that were naturally infected by Rickettsia sp. strain Atlantic rainforest (designated as infected groups); the two others started from noninfected females (designated as control groups). All colonies were reared in parallel from F0 engorged female to F2 unfed nymphs. Tick-naïve vesper mice (Calomys callosus) or domestic rabbits were used for feeding of each tick stage. Rickettsia sp. strain Atlantic rainforest was preserved by transstadial maintenance and transovarial transmission in A. ovale ticks for at least 2 generations (from F0 females to F2 nymphs), because nearly 100% of the tested larvae, nymphs, and adults from the infected groups were shown by PCR to contain rickettsial DNA. All vesper mice and rabbits infested by larvae and nymphs, and 50% of the rabbits infested by adults from the infected groups seroconverted, indicating that these tick stages were vector competent for Rickettsia sp. strain Atlantic rainforest. Expressive differences in mortality rates and reproductive performance were observed between engorged females from the infected and control groups, as indicated by 75.0% and 97.1% oviposition success, respectively, and significantly lower egg mass weight, conversion efficiency index, and percentage of egg hatching for the infected groups. Our results indicate that A. ovale can act as a natural reservoir for Rickettsia sp. strain Atlantic rainforest. However, due to deleterious effect caused by this rickettsial agent on engorged females, amplifier vertebrate hosts might be necessary for persistent perpetuation of Rickettsia sp. strain Atlantic rainforest in A. ovale under

    Full Text Available A total of 128 ticks of the genus Amblyomma were recovered from 5 marsupials (Didelphis albiventris - with 4 recaptures - and 17 rodents (16 Bolomys lasiurus and 1 Rattus norvegicus captured in an urban forest reserve in Campo Grande, State of Mato Grosso do Sul, Brazil. Of the ticks collected, 95 (78.9% were in larval form and 22 (21.1% were nymphs; the only adult (0.8% was identified as A. cajennense. Viewed under dark-field microscopy in the fourth month after seeding, 9 cultures prepared from spleens and livers of the rodents, blood of the marsupials, and macerates of Amblyomma sp. nymphs revealed spiral-shaped, spirochete-like structures resembling those of Borrelia sp. Some of them showed little motility, while others were non-motile. No such structures could be found either in positive Giemsa-stained culture smears or under electron microscopy. No PCR amplification of DNA from those cultures could be obtained by employing Leptospira sp., B. burgdorferi, and Borrelia sp. primers. These aspects suggest that the spirochete-like structures found in this study do not fit into the genera Borrelia or Leptospira, requiring instead to be isolated for proper identification.

    Full Text Available We studied some parameters of the parasitism by the mite Hannemania sp. on the endemic frog Hylodes phyllodes in the Atlantic Forest of Ilha Grande (Rio de Janeiro State, Brazil. Prevalence, mean abundance, mean intensity and total intensity of infestation, body regions infected, and host sexual differences in parasitism rate of the larvae of Hannemania sp. on individuals of H. phyllodes were assessed. Prevalence was 86.5% (N = 37; total of 1,745 larvae of Hannemania sp for male hosts and 91.7% (N =12; total of 330 larvae for female hosts, with no significant difference between the sexes. Overall prevalence of Hannemania sp. on H. phyllodes was 87.7%. Mean intensity of infestation in males (54.5 ± 42.5; range 1-173 larvae was higher than in females (29.9 ± 47.6; range 1-166. We conclude that the rates of intensity, abundance, and prevalence of Hannemania larvae parasitizing Hylodes phyllodes at Ilha Grande were considerably high, suggesting that this species of anuran constitutes a relevant host for this mite species to complete its lifecycle in the area. Differences between males and females in infestation rates probably reflect their differential use of space in the forest.

    Full Text Available As Rocky Mountain Spotted Fever is the most common tick-borne disease in South America, the presence of Rickettsia sp. in Amblyomma ticks is a possible indication of its endemicity in certain geographic regions. In the present work, bacterial DNA sequences related to Rickettsia amblyommii genes in A. dubitatum ticks, collected in the Brazilian state of Mato Grosso, were discovered. Simultaneously, Paracoccus sp. was detected in aproximately 77% of A. cajennense specimens collected in Rio de Janeiro, Brazil. This is the first report of Paracoccus sp. infection in a specific tick population, and raises the possibility of these bacteria being maintained and/or transmitted by ticks. Whether Paracoccus sp. represents another group of pathogenic Rhodobacteraceae or simply plays a role in A. cajennense physiology, is unknown. The data also demonstrate that the rickettsial 16S rRNA specific primers used forRickettsia spp. screening can also detect Paracoccus alpha-proteobacteria infection in biological samples. Hence, a PCRRFLP strategy is presented to distinguish between these two groups of bacteria.

    ABSTRACT: In most Brazilian municipalities, urban development was not based on adequate planning; one of the consequences was the reduction of the original vegetation, limiting the forest formations to scarce and isolated fragments. In Campinas, São Paulo, Brazil, the vegetation fragmentation was mainly related to the expeditions and to the cycles of sugar cane and coffee. In this way, the present study aims to identify, quantify and evaluate the remaining arboreal vegetation spatial distribution in the Anhumas River Basin - Campinas/SP, Brazil. This study was developed with the aid of GIS software and field visits in order to construct a diagnosis of these areas and subsidize future actions required and to discuss the influence of urbanization on the original vegetation cover. The area was initially occupied by the Atlantic Forest (semi-deciduous forest) and drains one of the oldest urban occupation areas in the municipality; according to researchers, based on the water and geomorphological conditions of the basin, it can be subdivided into high, medium and low course. With a total area of 156,514 km2, only 16.74% are classified as green areas; where just 1.07% and 6.17% of total area represents forests and reforestation areas, respectively. The remaining green areas consists of: wetlands close to water bodies, but with no presence of trees and shrubs (area of 0.12% of the basin); urban green space, including parks and squares (2.19%); and natural field, constituted by natural non-arboreous vegetation (7.18%). In a scenario like this, a characteristic situation is the forest fragmentation; this process results in native vegetation remnants, isolated and more susceptible to external interference, coming from, for example, the proximity to agricultural areas or others land uses. The ecological knowledge of the remnants and their correct management can not only make it possible to diagnose current problems and to estimate future influences, but also to point out the

    Few molecular studies have been done concerning the molecular characterization of Hepatozoon species among domestic and wild felids. The present work aimed to characterize molecularly the presence of Hepatozoon sp. DNA in cat blood samples from São Luís Island, Maranhão state, Northeastern Brazil. EDTA-whole blood samples were collected from 200 domestic cats with outdoor and wood areas access from São Luís, Maranhão, Brazil. Each sample of extracted DNA was used as a template in PCR reactions aiming to amplify a partial sequence of 18S rRNA of Hepatozoon spp. We also performed sequence alignment to establish the identity of the parasite species infecting these animals using DNA sequences based on 18S rRNA. From 200 sampled cats, Hepatozoon DNA was only found in one animal (0.5%). The found Hepatozoon DNA showed 97% of identity with Hemobartonella felis isolates 1 and 2 from Spain. When analyzing the phylogenetic tree, the found Hepatozoon DNA was in the same clade than H. felis isolates. Our findings suggest that more than one species of Hepatozoon could infect felids in Brazil.

    Full Text Available Neospora caninum is a protozoan parasite which affects dogs as definitive hosts and several mammalian species as intermediate hosts mainly causing abortions and central nervous system disorders. The reemerging population of cart horses for carrying recycling material in urban areas of major cities in Brazil may have an impact on disease spreading, and these animals may be used as sentinels for environmental surveillance. Thus, the present study investigated the frequency of Neospora sp. antibodies in cart horses from Curitiba and surrounding areas, Paraná State, Southern Brazil. IgG antibodies against Neospora sp. were detected using indirect fluorescence antibody test (IFAT, and titers equal to or higher than 1:50 were considered reactive. Of all samples, 14/97 (14.4% were positive: 2/29 (6.9% were younger than 5; 5/26 (19.2% between 6 and 9; and 6/31 (19.4% older than 10 years of age. One of the 11 animals with unknown age was positive (9.1%. Cart horses are likely to be more exposed to dog feces and to Neospora sp. oocyst contamination in urban settings and a lower frequency of disease in dogs may have a negative impact on horse infection risk in these areas.Neospora caninum é um protozoário parasita que afeta cães como hospedeiros definitivos e diversos mamíferos como hospedeiros intermediários, envolvido em abortos e distúrbios do sistema nervoso central.

    Full Text Available Rhinoxenus bulbovaginatus n. sp. is described from the nose of Salminus maxillosus (Characidae collected in the basin of the rio Paraná, near the city of Porto Rico, state of Paraná, Brazil. The new species can be differentiated from the other three species in the genus by the morphology of the copulatory complex, vagina, and ventral anchor. The sister group relationship of the known species of Rhinoxenus was determined using techniques of Phylogenetic Systematics (Cladism. The resulting cladogram (C.I.=100% indicates that the new species is most closely related to R. piranhus Kritsky, Boeger and Thatcher, 1988. The other two species of the genus, R. arietinus Kritsky, Boeger and Thatcher, 1988 and R. nyttus Kritsky, Boeger and Thatcher, 1988, both parasites of Anostomidae fishes, have a paraphyletic position in the cladogram, suggesting that the origin of at least one of them can not be associated to cospeciation.

    The present work studied helminth parasites of "pacu-manteiga", Myleus tiete (Osteichthyes: Characidae) from Volta Grande Reservoir, MG, Brazil. Fishes with 142.6 +/- 24.7 g weight and 17.3 +/- 1.0 cm total length were collected. Five out six analysed fish (prevalence 83.3%) were parasitized in the intestine with an average of 535.6 +/- 334.6 oxyurid nematodes per fish. The helminth was identified as Ichthyouris voltagrandensis n.sp. (Nematoda: Pharyngodonidae). It differs from I. brasiliensis (Moravec et al., 1992a) by the absence of lateral alae, higher measures of tail and caudal alae of males, esophageal isthmus length, distance of excretory pore from anterior end and spicule length. In addition, eggs were provided by two long filaments in just one pole and by the first time the authors observed flagellate spermatozoa from dissected males. The authors exposes comparative table of measures of the five described species of the genus Ichthyouris.

    Full Text Available The Canchim?s creek watershed in São Carlos, SP, Brazil, was chosen to evaluate water quality affected by dairy and beef cattle production systems based on tropical pasture. The water samples were collected monthly, during three years, at six sampling points: spring in a tropical forest, spring in an intensive dairy production system, two dam springs, and stream water upward and at the delta. Results showed differences (P<0.01 among sampling points for the mean parameters. True color, hardness, turbidity, electric conductivity, alkalinity, pH, chemical oxygen demand and consumed oxygen explained well differences among sampling points. According to current legislation standards, water quality fitted with most of the established parameters for class 2, with exception of phosphate and iron. The high levels of total phosphorus, except in the forest spring, classified this water in an eutrophic class, even where soil and water conservation practices were considered adequate.

    Full Text Available The aim of this study was the detection of Campylobacter sp. in raw chicken sausages using the methods ISO 10272-1 and ISO 10272-2. The overall prevalence of Campylobacter sp. in the samples tested was 16.67%, representing a serious risk to the health of consumers, particularly if measures guaranteeing proper cooking of foods and prevention of cross-contamination are not adopted. Furthermore, the majority of campylobacteriosis cases in humans are caused by consumption or improper handling of contaminated raw or undercooked poultry meat, which constitute the main vehicle of this infection.

    Full Text Available Apresenta-se os resultados de uma pesquisa que evidenciou a interveniência dos significados culturais no comportamento informacional. Com base nas teorias dos estudos de usuários da informação e do aspecto social da Ciência da Informação, foi analisado o comportamento informacional dos pais de crianças com Síndrome de Down, por meio de pesquisa documental e entrevista semiestruturada. A pesquisa comparou dois grupos de pais, um grupo com crianças nascidas nos Anos 2009 a 2013 e outro grupo com crianças nascidas nas Décadas de 1960 a 1980. Nesses contextos, considerou-se o momento do diagnóstico no reconhecimento da necessidade de informação, a busca e o uso da informação para auxiliar no desenvolvimento socioeducativo dos filhos. Os resultados encontrados indicam para a influência dos significados culturais atribuídos a anomalia, das interações sociais e da ação conjunta da família para promoção do desenvolvimento e melhoria da qualidade de vida da pessoa com Síndrome de Down. Entende-se, portanto, que o acesso a informação para os pais é fator de conformação no desenvolvimento das crianças com Síndrome de Down, com vistas a promover suas potencialidades e sensibilizar a sociedade para o processo de inclusão social. No entanto, a informação perpassa as construções histórico-sociais reveladas nos significados culturais, determinantes das mudanças ocorridas nos diversos contextos informacionais relacionados ao tempo e ao espaço que ocorrem.

This work has the aim of showing, in a theoretical and practical study, the problems caused by the atmospheric-pollutant emission, through natural or anthropogenic sources. In a period of 1 year (nov/94-nov/95), it was realized a practical work on rainwater, which consisted of collecting and, afterwards, analysing some physical and chemical parameters of this water, such as acidity, ionic concentrations, etc, with the purpose of characterizing the rainwater in Cidade Universitaria (SP, Brazil). After ending the practical part, it was possible to observe a 1,236.71 mm/y pluviosity, characterized by rainy summer and dry winter. The chemical-constituent-concentration analysis show us the predominance of SO{sup 2-}{sub 4} and Ca{sup 2+}, and a continental-origin water). The region of sao Paulo (Brazil), site of this study, is one of the largest metropolitan and industrialized areas of the world, which includes 18 million people, beside to an enormous industrial and vehicular complex. The acidity in the rain water is a complex problem and it must be treated by a range of disciplines to have a better comprehension of the cause/effects of the acid rain.

Sixty-five mammals, comprising Didelphis albiventris, Cerdocyon thous, Lycalopex vetulus, Cebus apella, Dasyprocta azarae, Dasypus novemcinctus, Procyon cancrivorus and Nasua nasua, were captured. Blood samples were collected for parasite cultivation. Antibodies were investigated by direct agglutination test (DAT using Leishmania (Viannia braziliensis as antigen. Flagellates were observed in blood cultures of 14 (35.9% Didelphis albiventris. Anti-Leishmania antibodies were detected in 31 (51.6% specimens of Cerdocyon thous, Lycalopex vetulus, Cebus apella, Dasyprocta azarae, Procyon cancrivorus and Nasua nasua. These results suggest that Cerdocyon thous and Lycalopex vetulus (crab-eating fox, Cebus apella (capuchin monkey, Dasyprocta azarae (agouti, Procyon cancrivorus (crab-eating raccoon and Nasua nasua (coati play an important role in the ACL transmission cycle in the northwestern region of Paraná, Brazil.

    Full Text Available This work had as objectives the study of the physical and mechanical characteristics of maize kernels in relation to the contamination by Fusarium sp and by zearalenone in twenty landraces of maize from the southern region of Brazil. From the analyzed samples, 60 % has been considered to have a hard endosperm type and 40 % an intermediary one. A correlation between the physical and mechanical variables was observed as an indication that the higher is the proportion of hard endosperm, more dense will be the kernel and more force for its rupture will be necessary. The level of contamination by Fusarium sp was between 5.5 and 24.75% among the analyzed grains, correlating positively with the flotation index, indicating that the landraces of maize with a softer endosperm can present a higher contamination by this genus. The presence of zearalenone was verified in 75 % of the samples, in concentrations varying from 50 to 640 µg kg-1.Este trabalho teve por objetivos verificar as características físicas, mecânicas, contaminação por Fusarium sp e por zearalenona e suas relações, em vinte variedades crioulas de milho da região sul do Brasil. Verificou-se que das amostras analisadas, 60% foram consideradas como possuidoras de endosperma do tipo duro e 40% com endosperma do tipo intermediário. As variáveis físicas e mecânicas se correlacionaram, indicando que quanto maior a proporção de endosperma vítreo, mais denso e maior a força necessária até a ruptura do grão. A contaminação por Fusarium sp esteve entre 5,5% e 24,75% nos grãos analisados, correlacionando-se positivamente com o índice de flotação, indicando que as variedades crioulas de milho com uma maior proporção de endosperma macio podem apresentar uma maior contaminação por Fusarium sp, sugerindo-se a utilização de variedades crioulas com a textura do endosperma predominantemente vítrea.

MÉTODOS: As 9 áreas foram agrupadas em 4 estratos, diferenciados pelo uso e ocupação do solo. Foram coletadas larvas e pupas numa amostra de cerca de 500 imóveis em cada área. RESULTADOS: Apesar do pneu e lona apresentarem as maiores taxas de positividade para Aedes aegypti, o ralo, juntamente com outros recipientes fixos nas edificações foram altamente predominantes entre os recipientes positivos (32 a 76% dos recipientes positivos. As áreas coletivas de prédios e os imóveis não residenciais de grande porte apresentaram as maiores taxas de positividade para Aedes aegypti enquanto os apartamentos, as menores. Os níveis de infestação foram maiores na área residencial com predominância de prédios de apartamentos, onde 76% dos criadouros detectados foram recipientes fixos nas edificações. CONCLUSÕES: Esses conhecimentos são importantes subsídios para a estratégia de controle, pois reforçam a necessidade de atenção especial para determinados tipos de imóveis, bem como da adequação da norma técnica de ralo de água pluvial e da melhoria de manutenção das edificações.

    Full Text Available Abstract Wild animals play an important role in carrying vectors that may potentially transmit pathogens. Several reports highlighted the participation of wild animals on the Anaplasma phagocytophilum cycle, including as hosts of the agent. The aim of this study was to report the molecular detection of an agent phylogenetically related to A. phagocytophilum isolated from a wild bird in the Midwest of the state of Paraná, Brazil. Fifteen blood samples were collected from eleven different bird species in the Guarapuava region. One sample collected from a Penelope obscura bird was positive in nested PCR targeting the 16S rRNA gene of Anaplasma spp. The phylogenetic tree based on the Maximum Likelihood analysis showed that the sequence obtained was placed in the same clade with A. phagocytophilum isolated from domestic cats in Brazil. The present study reports the first molecular detection of a phylogenetically related A. phagocytophilum bacterium in a bird from Paraná State.

A planta colhida em três municípios do Estado de Santa Catarina, dessecada na sombra a temperatura ambiente, demonstrou possuir toxidez também para essa espécie animal. Porém a sua toxidez para coelhos foi muito variável. Os experimentos realizados não permitem concluir que a procedência da planta, o seu estado de evolução ou a época do ano da colheita, sejam fatores que influenciam a sua toxidez. Já em relação ao quadro clínico, os achados de necropsia e histopatológicos, a planta teve um comportamento muito constante. Os coelhos mostraram os primeiros sintomas de intoxicação entre 3 horas e 24h49min após o começo da administração da planta. A evolução do quadro clínico foi de 1 a 4 minutos. Os sintomas consistiram sempre em que o animal subitamente começava a fazer movimentos desordenados, geralmente violentos; finalmente ficava caído, tinha respiração dispnéica com movimentos respiratórios cada vez mais espaçados, dava alguns gritos e logo morria. Os achados de necropsia se resumiram em congestão hepática e esplenomegalia; o fígado ao corte tinha a lobulação nítida, às vezes com o centro dos lóbulos mais claro. Os exames histopatológicos revelaram alterações regressivas e circulatórias no fígado, rim e baço.

    This paper describes part of a multicenter study sponsored by the Pan American Health Organization to assess health care reforms and their implications for nursing in several countries. The objective of this research was to learn the views of nurses working in philanthropic hospitals in Ribeirão Preto, in the state of São Paulo, Brazil, regarding the changes in nursing practice coming from Brazil's health care reform and implementation of the Unified Health System (UHS). Data were obtained through structured interviews with seven nurses who met the selection criteria, from the three philanthropic hospitals in Ribeirão Preto. The nurses reported a decline in the quality of care and in the number of beds for UHS patients. The nurses reported that UHS implementation initially led to infrastructure improvements in the philanthropic hospitals. However, the reforms eventually shifted toward improving the care of private and privately insured patients. In addition, the nurses emphasized their heavy work loads and low pay. The nurses' reports indicated that Brazil's UHS is going through a crisis. In general, the nurses linked this crisis to problems in funding and allocation of resources.

    In this study it was assessed the occupational exposure to {sup 222}Rn at IPEN, SP, Brazil, nuclear materials storage site through the committed effective dose received by workers exposed to this radionuclide. The radiation dose was calculated through the radon concentrations at nuclear materials storage site. Radon concentrations were determined by passive detection method with solid state nuclear detectors (SSNTD). The SSNTD used in this study was the polycarbonate Makrofol E; each detector is a small square plastic of 1 cm{sup 2}, placed into a diffusion chamber type KFK. It was monitored 14 points at nuclear materials storage site and one external point, over a period of 21 months, changing the detectors every three months, from December 2004 to September 2006. The {sup 222}Rn concentrations varied from 196 {+-} 9 and 2048 {+-} 81 Bq{center_dot}m{sup -3}. The committed effective dose due to radon inhalation at IPEN nuclear materials storage site was obtained from radon activity incorporated and dose conversion factor, according to International Commission on Radiological Protection procedures. The effective committed dose received by workers is below 20 mSv{center_dot}y{sup -1}. This value is suggested as an annual effective dose limit for occupational exposure by ICRP 60. (author)

Muitas dessas moléculas não são totalmente metabolizadas no organismo animal e seus resíduos têm sido detectados em amostras de solo, água superficial e subterrânea. A ocorrência desses resíduos no ambiente pode favorecer a resistência de microrganismos aos agentes antibióticos, além de causar problemas de ordem toxicológica a determinados organismos vivos. Os antibióticos de uso veterinário são, no geral, representados por moléculas anfóteras, com vários grupos funcionais ionizáveis (diferentes valores de pKa, massas molares bastante variáveis (172 a 916 g mol-1 e baixos potenciais de volatilização (pressão de vapor Antibiotics are used in large quantities in livestock. Many of these molecules are not fully metabolized by the animals, leaving detectable residues in soil, surface water and groundwater samples. The occurrence of these residues in the environment can favor microorganism resistance to antibiotic agents, in addition to toxic effects on certain living organisms. In general, veterinary antibiotic molecules are amphoteric with many ionizable functional groups (different pKa values, rather variable molar masses (172 to 916 g mol-1 and low volatilization potential (vapor pressure < 1.1 x 10-11 mm Hg. In comparison to pesticides, these compounds have higher water solubility (Sw and lower methanol-water partition coefficients (log Kow, probably due to the presence of many ionizable functional groups, resulting in lower bioaccumulation and higher mobility potential in soils. The purpose of this paper was to evaluate antibiotic uses and importance of livestock in Brazil, to review their environmental fate in temperate climate, and finally to emphasize the need for research on the occurrence and behavior of these molecules in the predominantly highly weathered soils of tropical regions.

    Full Text Available The purpose of this study was to assess the current knowledge and recommendations of obstetricians and dentists as to the dental care to pregnant patients in the cities of Londrina/PR and Bauru/SP, Brazil. Questionnaires were distributed to professionals of both cities, arguing on the following issues: oral health during pregnancy; contact between prenatal care and dental care providers; prenatal fluoride supplementation; selection of therapeutic agents for local anesthesia, pain control and treatment of infection; and dental procedures that can be performed during each trimester. Data were analyzed by frequency of responses and statistical analyses were carried out using X² (type of workplace/service and t test (time since graduation, significant if p<0.05. Seventy-nine obstetricians and 37 dentists responded the questionnaires. Most physicians referred the patient to dental care only when a source of dental problem was mentioned, limiting the adoption of a preventive approach. Forty-three percent of dentists and 34% of obstetricians did not know the potential contribution of periodontal infection as a risk factor for preterm low birth-weight babies. There was divergence from scientific literature as to the recommendation of local anesthetics (dentists and obstetricians, prenatal fluoride supplementation (obstetricians and dental radiographs (dentists. The findings of this survey with dentists and obstetricians showed that dental management during pregnancy still presents some deviations from scientific literature recommendations, indicating the need to update these health care professionals in order to establish guidelines for prenatal dental care.

    Background, aim, and scope Contaminated sediments are a worldwide problem, and mobilization of contaminants is one of the most critical issues in environmental risk assessment insofar as dredging projects are concerned. The investigation of how toxic compounds are mobilized during dredging operations in the channel of the Port of Santos, Brazil, was conducted in an attempt to assess changes in the bioavailability and toxicity of these contaminants. Materials and methods Bulk sediment samples and their interstitial waters and elutriates were subjected to chemical evaluation and ecotoxicological assessment. Samples were collected from the channel before dredging, from the dredge's hopper, and from the disposal site and its surroundings. Results The results indicate that the bulk sediments from the dredging site are contaminated moderately with As, Pb, and Zn and severely with Hg, and that polycyclic aromatic hydrocarbon (PAH) concentrations are relatively high. Our results also show a 50% increase in PAH concentrations in suspended solids in the water collected from the hopper dredge. This finding is of great concern, since it refers to the dredge overflow water which is pumped back into the ecosystem. Acute toxicity tests on bulk sediment using the amphipod Tiburonella viscana showed no toxicity, while chronic tests with the sea urchin Lytechinus variegatus showed toxicity in the interstitial waters and elutriates. Results are compared with widely used sediment quality guidelines and with a sediment quality assessment scheme based on various lines of evidence. Conclusions The data presented here indicate that the sediments collected in this port show a certain degree of contamination, especially those from the inner part of the channel. The classification established in this study indicated that sediments from the dredged channel are impacted detrimentally and that sea disposal may disperse contaminants. According to this classification, the sediments are

    Full Text Available Nine species of birds - seven hummingbirds (Trochilidae and two Passeriformes - were observed visiting the flowers of Erythrina speciosa Andrews (Fabaceae, a hummingbird-pollinated species present on the campus of Londrina State University, Paraná State, Brazil. Nectar in bagged flowers bore little relationship with nectar in flowers opened to foragers either regarding quantity or diurnal pattern of availability. Birds were more frequent early in the morning and their activity on flowers further declined, apparently following the pattern of nectar availability. The manner to which birds probed the flowers and, in consequence, their role on pollination were greatly determined by morphological traits and approaching behavior of birds. E. speciosa seemed best suited for pollination by long-billed hummingbirds but some short to medium-billed species may play some role on its pollination.Nove espécies de aves - sete beija-flores (Trochilidae e duas aves Passeriformes - foram observados visitando as flores de Erythrina speciosa Andrews (Fabaceae, uma espécie polinizada por beija-flores presente no campus da Universidade Estadual de Londrina, Paraná, Brasil. O néctar em flores ensacadas apresentou pouca relação com aquele em flores expostas aos visitantes, tanto em termos de quantidade como em temos de padrão diurno de disponibilidade. As aves foram mais freqüentes de manhã e sua atividade nas flores diminuiu no transcorrer do dia, coincidindo com o padrão de disponibilidade de néctar. O comportamento de visita das aves e, em conseqüência, sua atuação na polinização da espécie foram em grande parte determinadas por características morfológicas e comportamentais destas. E. speciosa parece ser adaptada para polinização por beija-flores de bicos longos, embora espécies com bicos de comprimento curto a médio possam ter algum papel em sua polinização.

    2005-01-01

    We describe here an application of excess 222 Rn to estimate SGD in a series of small embayments of Ubatuba, Sao Paulo State, Brazil, covering latitudes between 23 deg 26'S and 23 deg 46'S and longitudes between 45 deg 02'W e 45 deg 11'W. Excess 222 Rn inventories obtained in 24 vertical profiles established from March/03 to July/05 varied from 345 ±±24 to 18,700 ± 4,900 dpm/m 2 . The highest inventories of excess 222 Rn were observed both in Flamengo and Fortaleza embayments, during summer campaigns (rainy season). The estimated total fluxes required to support inventories measured varied from 62 ± 4 to 3,385 +- 880 dpm/m 2 d. Considering these results, the SGD advective rates necessary to balance the fluxes calculated in Ubatuba embayments ranged from 0.1 x 10 -1 to 1.9 cm/d. Taking into account all SGD fluxes obtained, the percentual variability was 89% (seasonal variation in 3 years period, n = 24 measurements). Although, if we consider each year of study separately, the respective percentual variabilities estimated are 72% in 2003 (n = 10 measurements), 127% in 2004 (n = 6 measurements) and 97% in 2005 (n = 8 measurements).

    Full Text Available Abstract Occurrences of gastrointestinal parasites were assessed in fecal samples from 3,099 dogs in the metropolitan region of São Paulo, SP, that were treated at the Veterinary Hospital of the University of São Paulo Veterinary School. The samples were analyzed using the flotation and centrifugal sedimentation methods. The results were compared with those from previous studies (at different times. The frequency of each parasite was correlated with the dogs’ ages, breeds and gender, as well as the occurrences of diarrhea and the use of anthelmintics, by means of the chi-square or Fisher exact test. Partitioned chi-square tests were used to compare occurrences of each parasite and the times analyzed. Out of the total number of samples, 20.5% were positive and 16.1% (102/635 of these presented more than one genus of parasites. Ancylostoma spp. (7.1% and Giardia spp. (5.5% were the most frequent helminths and protozoa, respectively. Ancylostoma spp. was associated (p<0.05 with age (over one year, mixed breeds, sex (male and no use of anthelmintics. Dogs under one year and mixed breeds were associated with occurrences of Toxocara canis; and younger dogs with Giardia spp., Cryptosporidium spp. and Cystoisospora spp. Giardia spp. were also associated with dogs with a defined breed (p<0.05. All the parasites analyzed presented lower incidence in the last period analyzed than in the previous periods.

    Thirteen Gram-negative, aerobic, motile with polar flagella, rod-shaped bacteria were isolated from root nodules of Centrolobium paraense Tul. grown in soils from the Amazon region of Brazil. Growth of strains was observed at temperature range 20-36 °C (optimal 28 °C), pH ranges 5-11 (optimal 6.0-7.0), and 0.1-0.5%NaCl (optimal 0.1-0.3%). Analysis of 16S rRNA gene placed the strains into two groups within Bradyrhizobium. Closest neighbouring species (98.8%) for group I was B. neotropicale while for group II were 12 species with more than 99% of similarity. Multi-locus sequence analysis (MLSA) with dnaK, glnII, recA, and rpoB confirmed B. neotropicale BR 10247 T as the closest type strain for the group I and B. elkanii USDA 76 T and B. pachyrhizi PAC 48 T for group II. Average Nucleotide Identity (ANI) differentiated group I from the B. neotropicale BR 10247 T (79.6%) and group II from B. elkanii USDA 76 T and B. pachyrhizi PAC 48 T (88.1% and 87.9%, respectively). Fatty acid profiles [majority C 16:0 and Summed feature 8 (18:1ω6c/18:1ω7c) for both groups], DNA G + C content, and carbon compound utilization supported the placement of the novel strains in the genus Bradyrhizobium. Gene nodC and nifH of the new strains have in general low similarity with other Bradyrhizobium species. Both groups nodulated plants from the tribes Crotalarieae, Dalbergiae, Genisteae, and Phaseoleae. Based on the presented data, two novel species which the names Bradyrhizobium centrolobii and Bradyrhizobium macuxiense are proposed, with BR 10245 T (=HAMBI 3597 T ) and BR 10303 T (=HAMBI 3602 T ) as the respective-type strains.

    2013-01-01

    This paper presents a chronological study focusing the use of 210 Pb in four sediment cores collected at Ribeirão dos Bagres in the region of Franca, São Paulo State, Brazil. When evaluating the sedimentation rate by using the 210 Pb method, it was possible to monitor historical changes occurring in the concentrations of chromium present in the sediments. In order to do so, several specific parameters were determined in sediments, as chromium concentration, major oxides, organic matter, grain size, and chemical and physical–chemical parameters of waters. The sediments possessed a Cr concentration range of 0.83–26.25 mg/kg that is below the world's average of shales. The sedimentation rates obtained from the 210 Pb analysis were between 0.07 and 0.77 g cm −2 year −1 , while the linear sedimentation rate was from 0.6 to 3.2 cm/year. The adoption of the CIC (Constant Initial Concentration) 210 Pb model allowed characterize older sediments, aged 177 years, and younger sediments, aged 4 years. The organic matter in the sediments was more abundant in the first few centimeters of practically all profiles, and the analysis of oxides showed that silica is the major constituent of the sediments, in which there is predominance of sand and silt. In addition, the analysis of the physical and chemical parameters of waters indicated that they are suitable for navigation and natural harmony landscape. - Highlights: • Application of natural radionuclides in an important industrial center devoted to the production of leather for manufacturing shoes. • Study of a well-known site of environmental Cr contamination. • Use of the Pb-210 chronological CIC model to provide an approach of the historical Cr contamination in the region

    Land use changes and forest fragmentation result in biodiversity loss and displacement, with insects among the most affected groups. Among these, bark beetles (Curculionidae: Scolytinae) occupy a prominent position due to their close ties to food resources, i.e., trees, and importance as primary decomposers in forest ecosystems. Therefore, our study aimed to document scolytine biodiversity associated with landscape components that vary based on their physical or botanical composition. Bark beetle diversity was sampled monthly for 12 mo in an Atlantic forest remnant and five adjacent vegetation plots (mixed Agroforestry System-AFS, of native trees and fruit species; AFS of rubber trees and coffee plants; coffee monoculture; rubber monoculture; and pasture). In total, 1,833 individuals were sampled from 38 species of which 24 (63%) were detected in very low abundance. The remaining 14 species were more abundant and widespread almost in all areas. Hypothenemus hampei (Westwood), Premnobius cavipennis (Eichhoff), Hypothenemus sp1., and Xyleborus volvulus (Fabricius) were the most abundant. The greatest abundance and richness of bark beetles were found in the dry and cold season. The varied microclimatic conditions of the vegetation plots greatly affected the diversity of the Scolytinae. Solar radiation presented a significant negative effect on abundance in almost all the studied areas. The greatest scolytine diversity was found in anthropic areas with tree canopy structure. Open areas (pasture and coffee monocrop) had a lower species diversity. Similarly, a lower abundance and species richness were found for the Atlantic forest remnant. © The Authors 2017.

  2. The ecological dynamics of Barra Bonita (Tietê River, SP, Brazil reservoir: implications for its biodiversity

    JG. Tundisi

    Full Text Available Barra Bonita reservoir is located in the Tietê River Basin - São Paulo state - 22° 29" to 22° 44" S and 48° 10° W and it is the first of a series of six large reservoirs in this river. Built up in 1963 with the aim to produce hydroelectricity this reservoir is utilized for several activities such as fish production, irrigation, navigation, tourism and recreation, besides hydroelectricity production. The seasonal cycle of events in this reservoir is driven by the hydrological features of the basin with consequences on the retention time and on the limnological functions of this artificial ecosystem. The reservoir is polymitic with short periods of stability. Hydrology of the basin, retention time of the reservoir and cold fronts have an impact in the vertical and horizontal structure of the system promoting rapid changes in the planktonic community and in the succession of species. Blooms of Microcystis sp. are common during periods of stability. Superimposed to the climatological and hydrological forcing functions the human activities in the watershed produce considerable impact such as the discharge of untreated wastewater, the high suspended material contributions and fertilizers from the sugar cane plantations. The fish fauna of the reservoir has been changed extent due to the introduction of exotic fish species that exploit the pelagic zone of the reservoir. Changes in the primary productivity of phytoplankton in this reservoir, in the zooplankton community in the diversity and organization of trophic structure are a consequence of eutrophication and its increase during the last 20 years. Control of eutrophication by treating wastewater from urban sources, adequate agricultural practices in order to diminish the suspended particulate matter contribution, revegetation of the watershed and riparian forests along the tributaries are some possible restoration measures. Another action that can be effective is the protection of wetlands in

    Full Text Available Studies on the longitudinal processes in reservoirs, involving physical, chemical and biological processes have been thoroughly appraised, suggesting the existence of a longitudinal organization controlled by the entrance and circulation of water which inserts modifications in the structuring of the system. To evaluate this effect, the Salto Grande reservoir (Americana, SP was analyzed in 11 sampling stations in its longitudinal axis, in the rainy and dry seasons of 1997 considering the physical chemical and biological variables. Analyzing the results in agreement with the declining concentration degree of the river--barrage direction, a more significant correlation was verified in the dry period for total phosphorus (r² = 0.86, dissolved total phosphate (r² = 0.83, nitrite (r² = 0.93, inorganic phosphate (r² = 0.89, ammonium (r² = 0.84 and suspended material (r² = 0.85. In the rainy period, only nitrite (r² = 0.90 and conductivity (r² = 0.89 presented correlation with the distance of the dam, which demonstrates the effects of precipitation and the operational mechanism of the dam, as well as the distinction among the physical (sedimentation, chemical (oxidation and biological (decomposition processes in spatial heterogeneity of the system. These factors were decisive in the organization of these communities, with higher occurrence of rotifers and copepods in relation to cladocerans, the first ones being more abundant in the entrance of the Atibaia river, decreasing towards the dam direction, while copepods presented an inverse pattern. A distribution pattern similar to Copepoda was also verified for the Cladocera, evidencing a tendency to increase the density of organisms in the stations distant to the entrance of the Atibaia river, not being registered, however, a distribution gradient in the longitudinal axis, as observed for rotifers and copepods. In relation to the trophic degree a longitudinal gradient was also verified from

Após início de cultivo todos os parâmetros foram analisados segundo um delineamento inteiramente casualizado. As plântulas que se desenvolveram em baixas concentrações de K apresentaram sintomas visuais de deficiência de K, como clorose e necrose nas folhas mais velhas. Os cultivares apresentaram diferenças quantitativas entre si, relacionados à concentração de K presente no meio de cultura, seja em relação aos valores de MMS, ou quanto ao número de plântulas formadas. Em ambos os cultivares, foi observada uma relação direta entre o desenvolvimento de plântulas e as concentrações de K com otimização ao redor de 15 a 20 mM de K.The chemical composition of culture growth media to micropropagate plants should be devised to allow the best quality and high production of plant material.

    99m Tc is the most used radionuclide in nuclear medicine. In Brazil, the 99 Mo/ 99m Tc generators are produced exclusively by the Center of Radiopharmacy at IPEN-CNEN/SP, by importing 99 Mo from different suppliers. 99 Mo (t 1/2 = 66 h) is a fission product of 235 U, therefore, it can be accompanied by several radioisotopes that are highly prejudicial for human health, demanding a strict quality control of this product for generators safe use. The European Pharmacopoeia established some parameters and limits that evaluate the quality of the solution of sodium [ 99 Mo]molybdate, that is used as raw material for generator's production. The European Pharmacopoeia also recommends some analytical methods to perform these evaluations, however, it has been observed difficulties on the implementation of these methods by the generator's producers. These difficulties are probably related to the lack of practicability of the proposed methods and the extensive list of utilized reagents. In this work some procedures of the European Pharmacopoeia's quality control method for 99 Mo were evaluated. Different types of solid phase exchanger cartridges were tested for retention of 99 Mo in 3 different conditions. Cartridges that presented percentages of retention higher than 90% were also tested for separation of 99 Mo from possible contaminants (Ru e Te). The results shown that solid phase exchanger cartridges that presented percentages of retention of Mo higher than 90% also presented significant percentages of retention of Ru and Te. An alternative method for separation of 99 Mo from 131 I (other contaminant) are also proposed. (author)

    Urban forests are usually affected by several types of atmospheric contaminants and by abnormal variations in weather conditions, thus facilitating the biotic homogenization and modification of ecosystem processes, such as nutrient cycling. Peri-urban forests and even natural forests that surround metropolitan areas are also subject to anthropogenic effects generated by cities, which may compromise the dynamics of these ecosystems. Hence, this study advances the hypothesis that the forests located at the margins of the Metropolitan Region of São Paulo (MRSP), Brazil, have high concentrations of atmospheric contaminants leading to adverse effects on litter fall stock. The production, stock and decomposition of litter fall in two forests were quantified. The first, known as Guarapiranga forest, lies closer to the urban area and is located within the MRSP, approximately 20km from the city center. The second, Curucutu forest, is located 70km from the urban center. This forest is situated exactly on the border of the largest continuum of vegetation of the Atlantic Forest. To verify the reach of atmospheric pollutants from the urban area, levels of heavy metals (Cd, Pb, Ni, Cu) adsorbed on the litter fall deposited on the soil surface of the forests were also quantified. The stock of litter fall and the levels of heavy metals were generally higher in the Guarapiranga forest in the samples collected during the lower rainfall season (dry season). Non-metric multidimensional scaling multivariate analysis showed a clear distinction of the sample units related to the concentrations of heavy metals in each forest. A subtle difference between the units related to the dry and rainy seasons in the Curucutu forest was also noted. Multivariate Analysis of Variance revealed that both site and season of the year (dry or rainy) were important to differentiate the quantity of heavy metals in litter fall stock, although the analysis did not show the interaction between these two

    Full Text Available Este estudo defende que o comportamento aleatório pode tornar-se legítimo objeto de estudo de uma ciência do comportamento. Analisamos inicialmente algumas considerações que B. F. Skinner formulou sobre o comportamento aleatório em suas Contingências do Reforço. Segundo Skinner (1969/1975, o comportamento aleatório "não apresenta interesse como processo de comportamento". Apresentamos uma rigorosa definição de "comportamento aleatório". Sustentamos que o comportamento aleatório pode constituir objeto de análise funcional, examinando alguns estudos empíricos que se têm conduzido sobre o comportamento aleatório. Apresentamos ainda algumas dificuldades empíricas e teóricas que podem afetar as investigações nessa área. Concluímos que o comportamento aleatório é um fascinante e importante tópico para uma completa ciência do comportamento.

MÉTODOS: Trata-se de um estudo descritivo exploratório, de natureza qualitativa. Foram entrevistadas oito mulheres portadoras de diabetes tipo 2 em uma Unidade Básica de Saúde do município de Ribeirão Preto, SP, em janeiro de 2003. Foi utilizada entrevista semi-estruturada para a coleta dos dados. O referencial teórico adotado foi a teoria das representações sociais. Os registros audiogravados e transcritos foram submetidos à análise temática de conteúdo. RESULTADOS: Os resultados evidenciaram dificuldade no seguimento da dieta prescrita, em função dos diversos significados associados, tais como a perda do prazer de comer e beber, da autonomia e da liberdade para se alimentar. Assim, seguir a dieta adquire caráter extremamente aversivo e cerceador, tendo representação de que realizá-la traz prejuízos à saúde. A freqüente ausência de sintomas foi citada como um dos aspectos que dificultam o seguimento da dieta. Outra dificuldade foi tocar, olhar e manipular os alimentos durante o seu preparo e não poder ingeri-los. Os alimentos doces despontaram como algo extremamente desejado. Transgressão e desejo alimentar estão igualmente presentes na vida das pessoas entrevistadas. Seguir o padrão dietético recomendado elicia tristeza, e o ato de comer, muitas vezes, vem acompanhado de medo, culpa e revolta. CONCLUSÕES: O comportamento alimentar da mulher portadora de diabetes tipo 2 é bastante complexo e precisa ser compreendido à luz dos aspectos psicológicos, biológicos, sociais, culturais, psicológicos e econômicos para maior eficácia das intervenções educativas.OBJECTIVE: To explore type 2 diabetes women's thoughts, feelings and behaviors concerning diet.

    Studies on the sandfly fauna to evaluate natural infection indexes are still limited in the Brazilian Amazon, a region with an increasing incidence of cutaneous leishmaniasis. Here, by using a multiplex polymerase chain reaction directed to Leishmania kDNA and hybridisation, we were able to identify L. (Viannia) subgenus in 12 out of 173 sandflies captured in the municipality of Rio Branco, Acre state, revealing a positivity of 6.94%. By sequencing the Leishmania 234 bp-hsp70 amplified products from positive samples, infection by L. (V.) braziliensis was confirmed in five sandflies: one Evandromyia saulensis, three Trichophoromyia auraensis and one Pressatia sp. The finding of L. (Viannia) DNA in two Ev. saulensis corresponds to the first record of possible infection associated with this sandfly. Moreover, our study reveals for the first time in Brazil, Th. auraensis and Pressatia sp. infected by L. (Viannia) parasites. PMID:28076470

O grupo tinha idade entre 9 e 78 anos, com média de 39,2 e era composto de 57 homens e 93 mulheres. Com referência à sorologia, 84 eram positivos e 66 negativos para a infecção pelo Trypanosoma cruzi. A prevalência de alterações eletrocardiográficas foi significativamente maior entre os pretos, tanto soropositivos quanto soronegativos. As alterações eletrocardiográficas consideradas sugestivas de miocardiopatia chagásica, predominaram significativamente entre os positivos pretos. E mesmo entre os pretos negativos as alterações foram mais numerosas e de maior gravidade com respeito aos negativos brancos. Na opinião dos autores a maior prevalência e severidade das alterações eletrocardiográficas entre os pretos, podem ser atribuídos a vários fatores entre os quais se destacariam: a pobreza e marginalidade das pessoas de cor que implicam trabalhos mais pesados e desgastantes; habitações triatomínica; alimentação mais pobre quantitativa e qualitativamente. Outro fator negativo seriam os valores mais elevados de pressão arterial encontrados entre os pretos que, associados a possíveis influências de ordem racial, podem contribuir e/ou criar condições de patologia miocárdica.The pattern of ECG changes of 150 black individuals from rural areas of southern Rio Grande do Sul, Brazil, was compared with that of a group of 150 whites of similar age, sex and geographical residence.

    In this report, we describe Henneguya arapaima n. sp., a parasite of the gill arch and gall bladder of Arapaima gigas (pirarucu) collected in the Araguaia River, in the municipality of Nova Crixás, Goiás State, central Brazil. The plasmodia were white, round or ellipsoidal and measured 200-600 microm. Parasite development was asynchronous and the mature spores were fusiform and had smooth wall. The spores measurements were (range, with means+/-S.D. in parentheses): total length-48.4-53.1 microm (51.6+/-3.4 microm), body length-13.5-15.2 microm (14.2+/-0.8 microm), body width-5.1-6.1 microm (5.7+/-0.5 microm), body thickness-4.7-5.3 microm (4.9+/-0.2 microm) and caudal process length-38.0-41.2 microm (38.3+/-2.9 microm). The polar capsules were elongated and of unequal size, with lengths of 6.3-6.8 microm (6.5+/-0.2) and 6.2-6.6 microm (6.3+/-0.1) for the longest and shortest axes, respectively. Capsule width was 1.4-1.6 microm (1.5+/-0.1). Histological analysis showed that the plasmodia occurred in the tunica adventitia of the gall bladder and were delimited by a thin capsule of connective tissue. In the gill arch, the plasmodia were also surrounded by connective tissue similar to the endomesium of striated skeletal muscle cells. Sixty-five juvenile specimens of A. gigas weighing 1.0-25.0 kg were examined, 17 (26.1%) of which were infected. Of these, 14 (82.3%) had cysts in the gall bladder, two (11.7%) had cysts in the gill arch and only one (5.9%) had cysts in both organs. When the fish were grouped by weight, the prevalence of infection in fish weighing up to 10.0 kg (20.7%) was significantly lower than in fish weighing 10.1-25.0 kg (50%) (G=3.93; d.f.=1; p<0.05).

O estudo da geometria bidimensional (horizontal e vertical dos horizontes em uma toposseqüência possibilitou o detalhamento da morfologia do solo. Para estudar a dinâmica da água no ambiente de desenvolvimento das plantas nativas, foram obtidas curvas de retenção, análise granulométrica e medidas de condutividade hidráulica saturada no campo, utilizando o permeâmetro de Guelph. O monitoramento da umidade do solo in situ, utilizando o sensor WCR, e da distribuição de chuvas foi realizado no período de novembro de 2003 a novembro de 2004. Os solos foram classificados de montante a jusante em Latossolo Vermelho, Latossolo Vermelho-Amarelo, Latossolo Amarelo e Gleissolo Háplico. O alto teor de argila no horizonte de subsuperfície do Gleissolo, em contraste aos Latossolos com maior teor de areia, determina menor drenagem, maior retenção hídrica e baixa condutividade hidráulica nesta camada, não atingindo a saturação em nenhum momento do ano monitorado. O comportamento físico-hídrico dos solos é influenciado pelas condições do relevo, evidenciado pela transição lateral contínua de cor, textura e estrutura dos solos na toposseqüência, e pela pluviosidade. Em superfície, ocorre uma oscilação da umidade do solo intimamente ligada a eventos chuvosos. Em subsuperfície, este efeito é menos intenso, sendo deslocado no tempo. A disponibilidade de água em toda a toposseqüência é limitada na estação seca e também em parte da estação úmida, o que deve definir as características florísticas da formação florestal da parcela e determinar a distribui

Arrival and absconding of Africanized honey bee (AHB colonies in the semiaridmunicipality of Canindé and the coastal humid city of Fortaleza (120 km apart were recorded weekly from January 1999 to December 2001, and the data compared to rainfall records in both areas. Results showed that AHB colonies only nest in the semiarid during the rainy season and abscond during the dry season, the opposite from observations taken in Fortaleza. Only 5% of colonies remained in the semiarid area for the entire year due to ant (Camponotus sp. attacks and shortage of nectar and water during the dry season, with most colonies migrating to coastal areas where the weather is milder and many plant species bloom at that time of year. Excessive rainfallprobably pushes AHB colonies back to the semiarid during the rainy season. We concluded that absconding and migration are strategies that allow AHB colonies to survive in the semiarid NE of Brazil, contrary to European honeybees, which have never succeeded in establishing wild colonies in the region.Os movimentos de colônias silvestres da abelha melífera africanizada (Apis mellifera L. no Estado do Ceará, Brasil, foram investigados com o objetivo de compreender variações anuais em sua população.

    Full Text Available Os estudos sobre o comportamento das aves, principalmente as galinhas, datam de 1912, quando o gênero Gallus passou a ser estudado com mais intensidade na área da Genética. Tais estudos eram simplesmente filosóficos até o início da década de 80, quando uma nova era da produção industrial avícola surgiu, objetivando um maior volume de produção econômica em todas as áreas de exploração. Esse objetivo reativou de maneira científica os estudos de comportamento das aves face à tecnologia de produção empregada nos sistemas de exploração, tornando-os mais acentuados já na década de 90, culminando com um simpósio internacional realizado nos Estados Unidos onde foram traçados os objetivos ou linhas de pesquisas na exploração avícola. O intuito era evitar problemas com os movimentos ambientalistas, traçando novos rumos para uma produção eficiente sem interferir no comportamento das aves já no início do novo milênio. Esta revisão, tem como objetivo principal uma análise científica e filosófica sobre o comportamento das aves em diversos métodos de exploração.Studies on poultry behavior initiated in 1972, at that time, fowls from Gallus domesticus species were the most important animal for the initial studies of Genetic. Since then, just the philosophical concepts where involved in those studies. However, at the beginning of 80 decade, these studies were intensified taking into account technological approaches for an economical industrial poultry production. Meanwhile, the reactions from activists involved in the behavior of the animal subjected to production became more strong at the beginning of 90's as well as those studies on chicken behavior. Finally, in 1998, an international symposium, promoted by chicken behavior scientists were held in the United States, in order to establish new methods of exploitation of poultry without interfering in its normal behavior, at the beginning of new millenium.

Nessa linha objetivou-se determinar a atividade hematófaga dessa espécie, tendo como parâmetros a posição estacionária e em movimento do homem utilizado como isca. MATERIAL E MÉTODO: A pesquisa foi desenvolvida numa chácara localizada na zona periurbana da cidade de Tremembé, Vale do Paraíba, Estado de São Paulo, Brasil. Aedes albopictus foi capturado sob duas modalidades técnicas de isca humana: uma correspondeu a período de 24 horas ininterruptas, com os coletores em ponto único, e outra, de duas horas, com os coletores visitando, por 5 min, 48 pontos, distando 10 m entre si, nos períodos da manhã e tarde. Ambas foram executadas mensalmente durante 12 meses (1989/90. RESULTADOS: As 24 capturas realizadas renderam 637 fêmeas de Ae.albopictus, sendo 54 (8,4% e 583 (91,6%, respectivamente, para posição estacionário e móvel, do coletor. Fez-se análise sobre a influência da mobilidade do hospedeiro como estímulo atrativo para esta espécie. A atividade horária detectada foi diurna, com picos às 6:00h, entre 13 e 14h, e o maior das 16 às 17 horas. A abundância de adulto correspondeu às estações verão/outono, mas na modalidade de coleta móvel a presença das fêmeas foi prolongada por todo o ano. A chuva e temperatura foram fatores de análise pelas suas correlações com a abundância e redução dos adultos de Ae.albopictus. CONCLUSÃO: Demonstrou-se ser complexa a influência de fatores endógenos e exógenos na prática da hematofagia de Aedes albopictus. Contudo pareceu claro que o comportamento desta prática, nas modalidades estudadas, demonstrou vôo direcional ao hospedeiro num raio supostamente pequeno, e vôo apetente, menos significativo, demonstrado pela posição estacionária do coletor.

From those collected in the agrosilvopastoral system, emerged 267 specimens of hymenopteran parasitoids belonging to 16 genera: Braconidae, Agathidinae (Alabagrus), Braconinae (Bracon), Microgastrinae (Cotesia, Diolcogaster, Glyptapanteles, Pholetesor and Protapanteles), Orgilinae (Orgilus); Ichneumonidae, Campopleginae (Casinaria, Charops and Microcharops); Chalcididae, Chalcidinae (Brachymeria and Conura); Eulophidae, Entedoninae (Horismenus), Eulophinae (Elachertus and Euplectrus). From the Lepidoptera larvae collected in the reforestation, emerged 68 specimens of hymenopteran parasitoids, belonging to 8 genera: Chalcididae, Chalcidinae (Conura); Ichneumonidae, Pimplinae (Neotheronia), Campopleginae (Charops and Microcharops) and Braconidae, Microgastrinae (Apanteles, Diolcogaster, Distatrix, Glyptapanteles and Protapanteles). The results of this study suggest the occurrence of a wide variety of Hymenoptera parasitoids in the studied environments.

    Full Text Available Amphisbaena arda sp. nov. is described based on a specimen obtained at Mocambo do Vento, on the left bank of the São Francisco river, Bahia state, Brazil. A. arda is a medium size amphisbaenian with a checkered black and white color pattern similar to the one present in the fuliginosa group but differing from that by having a lighter pigmentation, an uniformly white ventral surface, and by several other important morphological characters. A. arda is similar to Amphisbaena vermicularis in meristic characters currently used to assist amphisbaenian identification but can be separated from it by its color pattern, its flatter cephalic shields, and by the more ventral position of the nostril.

    Full Text Available There is still little knowledge about the behavior of the estuarine dolphins and also the way they react to the presence of different types of vessels. The aim of the present study was twofold: to investigate the behavior of estuarine dolphins in four locations in Pernambuco, Brazil, and also their reaction to the presence of common types of nautical crafts. The data of this study resulted from 48 fieldtrips to each of the four localities studied (ports of Recife and Suape, and beaches of Bairro Novo and Piedade, thus totaling 192 days of observations, with approximately 380 hours of actual sampling. Ten types of behavioral activities were counted for Bairro Novo beach and the port areas, but only four for Piedade beach. The greatest flows of boats were recorded in the port of Recife. Fishing boats were the commonest type in the port area of Recife and Bairro Novo beach, while tourist vessels predominated in the port of Suape and Piedade beach. During the observations of encounters between these boats and the estuarine dolphins, neutral reactions predominated for all the vessel types studied. The same type of reaction predominated when the distances at which the interactions between the animals and vessels occurred were correlated.Ainda se sabe pouco sobre o comportamento do boto-cinza, assim como a forma pela qual ele reage a diferentes tipos de embarcações.

    Full Text Available Em ensaios regionais instalados no ano agrícola de 1980/81, em Tremembé e Pindamonhangaba (SP, determinaram-se, em 37 cultivares de arroz irrigado, os fungos responsáveis por manchas em sementes de arroz e o comportamento desses cultivares em relação a cada fungo detectado. Amostras de sementes foram coletadas da produção total de cada parcela experimental, procedendo-se à separação visual das sementes manchadas e sem manchas e, posteriormente, aos cálculos da porcentagem de sementes manchadas e da porcentagem de perda de peso devida às manchas. Testes de patologia de sementes detectaram a presença das seguintes espécies de fungos: Alternaria sp. Cephalosporium sp., Cladosposium spp., Corynespora sp., Curvularia spp., Epicoccum spp., Fusarium moniliforme, Helminthosporium oryzae, Phoma spp., Pyricularia oryzae, Rhizoctonia solani, Rhynchosporium oryzae, Trichoconiella padwickii, Trichoderma sp. e Trichothecium sp. Diferenças altamente significativas entre o número de sementes manchadas e sem manchas foram observadas para os fungos H. oryzae, Phoma spp., R. oryzae e T. padwickii nos dois locais, patógenos então considerados os principais responsáveis pela manchas de sementes observadas. A análise conjunta das duas localidades para cada parâmetro revelou 32 cultivares com menor porcentagem de sementes manchadas do que o controle comercial, quatro cultivares com menor porcentagem de perda de peso devida às manchas, 24 com menor porcentagem de sementes com H. oryzae, seis com menor porcentagem de sementes com Phoma spp,, todos os cultivares com menor porcentagem de sementes com R. oryzae e onze com menor porcentagem de sementes com T. padwickii do que o controle comercial. Considerando todos os parâmetros avaliados na análise conjunta e obtidos para as duas localidades, concluiu-se que os cultivares PI-1291, PI-1356, PI-1377, IR 1544, P2-48, P2-S2, P2-S1-78, L-17-72 e GI-6904-6 apresentaram melhor comportamento que os demais

    Full Text Available O objetivo deste trabalho foi verificar o tipo de interação entre formigas e os cupins os quais habitam o mesmo ninho. Os experimentos foram de duas maneiras: A- para testar a relação de predação, os tratamentos usados foram: três formigas e um cupim, três formigas e três cupins, e três formigas e doze cupins; B- para testar a relação de proteção os tratamentos foram: três formigas e três cupins de um mesmo ninho e três formigas de um ninho diferente. Para verificar predação foram testadas diferentes origens de formigas e cupins. Os testes foram em arenas e placas de Petri. Os comportamentos observados foram: não responde; contato e abandono; agarra o cupim e luta. As espécies estudadas foram Camponotus sp. e Cornitermes silvestrii Emerson. No experimento A, nas arenas foi observado o comportamento de contato e abandono das formigas sobre um cupim significativamente diferente para formigas que não co-habitava com o cupim, já para um grupo de cupins o comportamento foi não responde. Na placa de Petri as formigas responderam ao contato com os cupins com comportamento de contato e abandono, morder e luta com o cupim, mas não houve diferença estatística entre os comportamentos. No experimento B observou-se luta entre as formigas de ninhos diferentes. Os experimentos mostraram que as formigas que co-habitam cupinzeiros não tiveram nenhuma resposta agressiva ou de predação com relação aos cupins dos quais co-habitam, mas também não tiveram comportamento de proteção com os mesmos, sugerindo que esta interação entre formigas e cupins é de inquilinismo.Behavior of Ants (Hymenoptera: Formicidae Co-inhabit of Termites (Isoptera: Termitidae in grassland.Abstract.

    Full Text Available OBJETIVOS: Descrever o perfil de adolescentes quanto ao apoio social e familiar, ao uso de drogas e os conhecimentos, as práticas e atitudes relacionadas à Aids e sua prevenção. MÉTODOS: Foram estudados 275 jovens internos, do sexo masculino, de um centro de internação da Fundação Estadual do Bem Estar do Menor (Febem, em São Paulo, SP. A pesquisa foi feita em duas fases: a primeira por meio de entrevistas semi-estruturadas com 20 internos; a segunda, com questionários para auto-respostas aplicados aos 275 internos, com perguntas fechadas referentes a características sociodemográficas, criminalidade, práticas sexuais, uso de drogas, conhecimento, atitudes e práticas relativas à Aids. RESULTADOS: Do total estudado, 90% dos jovens internos residiam com suas famílias antes da internação; todos haviam estudado em escolas públicas, ainda que 61% já houvessem abandonado os estudos; 12% já haviam usado drogas; e 5,5% eram usuários de drogas intravenosas. A maioria (98% era sexualmente ativa; 35% haviam tido mais de 15 parceiras(os sexuais ao longo da vida; 8% haviam tido experiências homossexuais (dentro ou fora da Febem; 12% já haviam trocado sexo por benefícios materiais; e 22% já eram pais. Muitos dos adolescentes afirmaram que adquirir o HIV "é parte da vida" e que suas vidas apresentam riscos piores, como sobreviver na criminalidade. Acreditam que o preservativo é frágil (83% e atrapalha a relação sexual (58%; 72% já haviam utilizado preservativo, mas apenas 9% o utilizavam sempre. CONCLUSÕES: Os adolescentes apresentaram um elevado risco de aquisição do HIV. Assim, torna-se necessário integrar a prevenção da Aids em sua problemática de vida e em temas como racismo, esperança pelo futuro, criminalidade, uso de drogas, direitos fundamentais, incluídos nestes os referentes ao sexo e à reprodução, mostrando existir alternativas a adquirir o HIV ou morrer na criminalidade.OBJECTIVES: To describe social and

    Full Text Available In youth A. gigas the risk of parasitic infections is very high, due to their feeding habit to prey on small invertebrates, which act as intermediate hosts of different endoparasite species, which can cause serious problems and high mortalities in fish farms. Thus, the aim of the present study was to identify the species that parasitize youth A. gigas raised in captivity in the Manacapuru municipality, Amazonas State and to evaluate their influence on the mortality of these fish. There were examined 66 youth A. gigas and non-parasite was recorded in the host gills. The intestine and stomach of the fish were parasitized by Hysterothylacium sp. larvae (L3 and Goezia spinulosa larvae (L4. The parasitic indexes were high for the two species, being recorded the highest rates of infection by Hysterothylacium sp. There was observed a weak positive correlation between the host standard length and the abundance of Hysterothylacium sp. The lesions observed in the stomach and intestine of the fish, together with the high parasite index values recorded for Hysterothylacium sp. and Goezia spinulosa, leads to the suspicion that the death of the fish was due to complications and damages caused by the presence of these parasites.

METHODS The parasites were isolated and a growth curve was performed in NNN and Schneider's media containing 10% foetal bovine serum. Parasite morphology was evaluated via light microscopy on Giemsa-stained culture smears, as well as scanning and transmission electron microscopy. Molecular taxonomy was based on a partial region (737-bp of the small subunit (18S ribosomal RNA gene and 708 bp of the nuclear marker, glycosomal glyceraldehyde-3-phosphate dehydrogenase (gGAPDH genes. Maximum likelihood and Bayesian inference methods were used to perform a species coalescent analysis and to generate individual and concatenated gene trees. Divergence times among species that belong to the T. cruzi clade were also inferred. FINDINGS In vitro growth curves demonstrated a very short log phase, achieving a maximum growth rate at day 3 followed by a sharp decline. Only epimastigote forms were observed under light and scanning microscopy. Transmission electron microscopy analysis showed structures typical to Trypanosoma spp., except one structure that presented as single-membraned, usually grouped in stacks of three or four. Phylogeography analyses confirmed the distinct species status of T. janseni n. sp. within the T. cruzi clade.

    Full Text Available O trabalho estuda a correlação entre a produção de um pomar de laranja, plantado no altiplano de Botucatu, SP, com as precipitações que ocorrem dezesseis meses antes da colheita e a idade do pomar. As plantas eram de laranjeira doce (Citrus sinensis (L. Osbeck, variedade Westin, de clone nucelar, enxertadas em porta-enxerto de limoeiro 'Cravo' (Citrus limonia Osbeck, plantadas em solo Terra Roxa Estruturada, a 810 m de altitude e em região de clima do tipo Cwb. A cultura foi conduzida de modo convencional e sem irrigação. Coletaram-se dados de produção, nos períodos entre o 3º e o 17º e entre o 21º e o 27º ano de idade do pomar, para análise do comportamento da produção e o efeito da idade e das precipitações na produção. Calcularam-se equações lineares múltiplas de regressão, entre a produção, idade do pomar e as precipitações mensais, nos períodos de pomar juvenil, adulto, senescente e adulto-senescente. A produção correlacionou-se com a idade e com valores mensais de precipitação. Os pequenos desvios observados entre os valores medidos e estimados de produção revelaram que as equações de regressão poderiam ser usadas na previsão de safra ou no controle de irrigação suplementar do pomar.This paper deals with the existence of correlation between the production of a sweet orange orchard, planted at the plateau of Botucatu, São Paulo State, Brazil, with the orchard age and the rainfall that occurred in the sixteen months before the picking season.

MÉTODO: 1.464 sujeitos foram entrevistados em seus domicílios com o CIDI para gerar diagnósticos DSM-III-R. Estatística descritiva demonstrou a prevalência de cognições e comportamentos relacionados ao suicídio pelas variáveis sociodemográficas e diagnósticos considerados (episódio depressivo maior, distimia, transtornos por uso de álcool ou substâncias. Realizamos também análises de regressão logística multivariada para estimar o efeito da comorbidade entre episódio depressivo maior/distimia e transtornos por uso de álcool ou substâncias em cognições e comportamentos relacionados ao suicídio. RESULTADOS: A presença de episódio depressivo maior e distimia foi significativamente associada a cognições e comportamentos relacionados ao suicídio. Em modelos de regressão multivariada, os preditores de cognições e comportamentos relacionados ao suicídio foram episódio depressivo maior (OR range = 2,3-9,2 e distimia (OR range = 5,1-32,6 mesmo na presença de transtornos por uso de álcool (OR range = 2,3-4,0 ou transtornos por uso de substâncias (OR range = 2,7-2,8.

The maxillipeds of the new species are large and project well beyond the lateral margins of the cephalothorax. Those of K. deetsi are much smaller. The third endopodal segments of K. deetsi are twice as long as the second endopodal segments and are provided with prominent marginal denticles. The second and third endopodal segments of the new species are rounded, of similar length and lack teeth.Kroyeria brasiliense sp. nov. proveniente de guelras de G. vitaminicus de Buen, 1950 do Rio Grande do Sul, é descrita baseada em 14 fêmeas adultas. A nova espécie aproxima-se de Kroyeria deetsi Dippenaar, Benz & Oliver, 2000, mas a nova espécie se distingue por apresentar os maxilípedes grandes e estendendo-se bem além das margens do cefalotorax. Os terceiros segmentos dos endopoditos de K. deetsi são duas vezes mais cumpridos que os segundos e têm dentículos marginais proeminentes. Os segundos e terceiros segmentos dos endopoditos da nova espécie são arredondados, de tamanhos parecidos e carecem de dentículos.

    Angelo Augusto Silva Sampaio

    Full Text Available Atualmente, não se pode pensar no estudo do comportamento humano sem considerar a abordagem científica a este objeto: o campo da Psicologia científica. Esse campo é disputado por diversos enfoques teóricos que divergem quanto ao modo como definem ciência e comportamento humano. A abordagem de B. F. Skinner foi bastante proeminente no século XX, mas ainda continua a ser mal-entendida. Partindo do desenvolvimento histórico de sua obra, o presente texto visa a iluminar alguns aspectos relacionados às noções de ciência e comportamento humano desse autor e ressaltar as transformações por que passaram. Analisam-se três tópicos da obra de Skinner: seu período inicial (de 1930 a cerca de 1938, a obra "Ciência e Comportamento Humano" de 1953, e as influências da Biologia. São enfatizados aspectos relevantes da sua teorização sobre o tema: busca por relações funcionais, ênfase nos dados empíricos, operacionismo, externalismo, multideterminação do comportamento, experimentalismo, previsão e controle, ética.

    The composition of groundwaters results mainly from water-rock reactions within aquifers. Among the various constituents of water, the rare earth elements (REE) and uranium can serve as tracers of geochemical processes and hydrological flow paths. The main objective of this study was to associate the chemical composition of groundwaters extracted from three distinct aquifer systems (crystalline, diabase and sedimentary) with that of the respective hosts rocks. The area of the study is located at the campus of University of Campinas (Campinas, SP). Samples of groundwater collected from four tubular wells were used to determine physicochemical parameters, major ions and trace elements, including the REE. The results confirm that the water of two wells (IMECC and IB) is predominantly influenced by the crystalline and diabase aquifers, while the other two (GM and FEF) by the sedimentary aquifer. Both the individual and normalized REE values of the four wells are distinct from each other, pointing to the heterogeneity of the local geology. The uranium concentration in the water of one well (GM) exceeded the guideline value for this element in drinking water. The U probably results from the oxidative dissolution of U-bearing phases in the sedimentary aquifer. However, the hydrochemical modeling indicated Ca{sub 2}UO{sub 2}(CO{sub 3}){sub 3} and CaUO{sub 2}(CO{sub 3}){sub 2}{sup 2-} as the major U dissolved species, which are considered non-toxic and non-bioavailable according to literature data.

    The coastline between Sao Sebastiao and Ubatuba cities and the shores of Sao Sebastiao, Anchieta and Mar Virado islands (Sao Paulo State, Brazil) are crosscut by several small swarms and isolated dykes trending N55E. The main rock types range from basic to intermediate, but also a conspicuous variety of alkaline lamprophyres occur side by side with the main group. The thickness of the basic to intermediate dykes vary widely, from a few centimeters to several metres, while the lamprophyres are a few tens of centimeters thick. The objective of this thesis is the petrographic, mineralogic, petrochemical and isotopic characterization of the basic and ultrabasic dykes that occur between the Sao Sebastiao and Ubatuba cities (State of Sao Paulo), also including some occurrences from the Sao Sebastiao, Mar Virado and Anchieta islands and from the Bairro Alto region (Folha de Natividade da Serra).

    Full Text Available Considering the fundamental role that the riparian vegetation plays in relation to maintenance of the environmental health of a watershed and the necessity of restoring sectors of the buffer zone without natural vegetation, in this paper we investigated what land cover classes occur along the riparian buffer stripes considered Area for Permanent Preservation (APP in the Sorocaba municipality, SP in three periods: 1988, 1995 and 2003. Based on GIS technology and using the drainage network map, the APP stripes (riparian buffer zones map was generated, and this map was overlaid to the land cover map (1988, 1995 and 2003 to provide a land cover map specifically of the riparian buffer zones. The results show that 58.43% of the APPs have no land cover of native vegetation and therefore, need to be reforested, representing 5,400 hectares to be restored.

  7. Mineralogical and structural transformations related to alterations in hydrothermal and climatological conditions of basic vulcanic rocks from northern Parana (Ribeirao Preto region, SP, Brazil)

    1987-01-01

    Detailed studies of the basic vulcanic rocks of northern Parana basin (Region of Ribeirao Preto, SP) reveled that these rocks were affected by pre-meteoric activity (hydrothermal alteration) before being exposed to the supergene system of alteration linked to the lithosphere/atmosphere interface. Mineralogical and structural transformation are studied. The appearance of sequential crystalline-chemical paragenesis in zones suggest that the hydrothermal activity occurred during two successives processes of alteration: the expulsion of the water from the rock during the later stages of magma cooling and the continous process of dissolution of the rock wall and the ionic diffusion involving the rock sistem of structural voids. The hydro-thermal action was followed by weathering action developing a thin 'front' of superficial alteration. This alteration system, can lead to the formation of three major levels of alteration horizons and superficial accumulations: alterites, glebular and suil surface materials. (C.D.G.) [pt

    The sand fly Lutzomyia (Lutzomyia) elizabethrangelae sp. nov. is described and illustrated based on the morphological characters of male and female specimens captured in sandstone caves in the municipality of Palmeirópolis, in the southern region of Tocantins state. The samples were collected as part of an entomological vector-monitoring project during the construction of the Peixe Angical Hydroelectric Plant. Based on the morphological characters of the new species, we believe this species can be included in the subgenus Lutzomyia. This species is closely related to two others, Lutzomyia forattinii Galati et al. 1985 and Lutzomyia almerioi Galati and Nunes 1999. The new species can be distinguished from Lutzomyia forattinii and Lutzomyia almerioi by the morphological characteristics of the male genitalia and the female cibarium. © The Authors 2015.

    Full Text Available The study of hydrographic basins as territorial units integrating the management of hydric resources is essential to guarantee sustainable use of natural resources in these basins. The establishment of the Paraíba do Sul hydrographic basins committee, in 1994, determined the need for management planning and action integration in the Paraíba do Sul basin which incorporates a variety of industries and intense land use. The Batedor river, in the municipality of Cruzeiro, SP, flows into the Passa Vinte which is an affluent of Paraíba do Sul river. Its mouth is located at 22°31’0.63”S and 45°01’2.07”W. Its farthest water contributing source lies about 8.5 km, near the Itaguaré peak 2,308 m high, in the Mantiqueira Mountain on the border of São Paulo and Minas Gerais States. To characterize land use in the Batedor hydrographic basin, Landsat imagery and topographic charts were analyzed based on remote sensing and geoprocessing techniques. This paper describes the study of impacts related to land and water resources use in the Batedor river basin and the generation of educational environmental material. Results have shown that this basin has good water supply, has no flooding risk and has several springs running down the Mantiqueira Moutain slopes that form young creeks with few meanders. Irregular human occupation for housing and subsistence agriculture, mainly banana plantations can be seen in deep slopes and riparian areas, as well as degraded pastures that indicate inappropriate land use and no conformance to pertinent legislation. The decrease in forest vegetation cover can cause severe erosion with significant soil loss and sediment deposition in the river, thus reducing water quality and quantity during the dry season. This basin is currently responsible for 70% of the Cruzeiro, SP water supply.

Once the users must know about the absorbed doses monthly and the need of keep the individuals records until the age of 75 years old and for, at least during 30 years after the end of the occupation of the individual, it became necessary to construct a database and a computerized control to manage the accumulated doses. This control, between 1991 and 1999, was effected by means of a relational database (Cobol 85 - Operating System GCOS 7 (ABC Telematic Bull)). After this period, when the company responsible for dosimetry went on to provide computerized results, the data were stored in a Paradox database (Borland). In 2004, the databases were integrated and were created a third database developed in Oracle (IBM) and a system that allowed the institutional Intranet users to consult their accumulated doses annually and the value of the total effective dose accumulated during working life.

In October 2010, 280 questionnaires were applied to a probabilistic sample of the population. A multivariate logistic regression model was built, creating five scenarios adjusted to the age and probability to pay according to the significant variables found. Concerning the WTP, 56% of the interviewees showed willingness to pay a monthly amount using the water bill as a vehicle for this. The WTP average was 1.94 US Dollar (USD, with a standard deviation of 1.91 USD. The total annual amount for the scenario that considers the whole population over 18 years old was of USD 3,930,616.80. The main argument for the negative WTP was that the interviewees could not afford it (14%.

    Galls induced by the larval stage of cecidosids (Lepidoptera: Cecidosidae) are complex, multi-trophic systems, still poorly studied. They may be associated with other insect feeding guilds, including inquilines, kleptoparasites, cecidophages, parasitoids, and predators. By causing death of the gall inducer early in life and altering the gall phenotype, inquilines may lead to misidentification of the true gall inducers. Here, we describe through light and scanning electron microscopy Cecidonius pampeanus , a new genus and species of cecidosid moth, from the Pampa biome, south Brazil. It induces unnoticed, small galls under swollen stems of Schinus weinmannifolius Mart. ex Engl. (Anacardiaceae). Such galls are severely attacked early in ontogeny either by unidentified parasitoids belonging to Lyrcus Walker (Pteromalidae) that feed upon the inducer, or by inquiline wasps of the genus Allorhogas Gahan (Braconidae). The inquilines modify the galls into large ones that last longer and promptly call attention. Free-living galls are rare and dehiscent, pupation of C. pampeanus occurring on the ground. Due to these reasons the true inducer has been overlooked in this case for more than a century. Additionally we inferred a phylogeny for Cecidosidae using sequences from mitochondrial and nuclear loci, and characterized genetic variation and gene flow across ten populations. Despite its natural history similarities with the African genus Scyrotis , Cecidonius is a much younger lineage, more closely related to the Neotropical cecidosids. C. pampeanus populations, which are now confined to a few mountain areas within its distribution range due to habitat destruction, are also genetically isolated, requiring conservation measures.

    The demand growing in Brazil by the radiopharmaceutical [ 18 F] FDG in positron emission tomography (PET-CT) and the 109,7 minutes half life claim special attention to the productive chain of this radiopharmaceutical. Since the [ 18 O]water irradiation until the tomograph patient scanning, in sequential procedures that may spent about six hours, all the productive chain stages must be as reliable as possible, because any stage failed will be perceived in productive chain extremity. The position indication absence from Load and Unload 18 F - Target System valve in Cyclotron Accelerators Center resulted in 18 F - production loss, Irradiation Room contamination and the increase workers dose responsible by operation and maintenance of irradiation systems. This study tested the behaviour of three types of position sensors (micro switch, reed switch and inductive sensor), into Irradiation Room 1.2 environment of the Cyclotron Accelerators Center, where there are high gamma radiation and neutrons rates because the routine 18 F - and 123 I production, through this test was possible to discover the fitter position sensor to run on 18 F - Target, and after rewriting the programmable logic controller software was possible avoid this type of fail at 18 F - production time in Cyclotron Accelerators Center, and to grow up the reliability on [ 18 F]FDG productive chain.

    Trad-SHM assay was used to check mutagenic potential of atmospheric contamination at Ibirapuera Park, located in Sao Paulo city, Brazil, and variation of risk along the year, besides determining which Tradescantia clone, BNL 4430 or KU-20, better indicates risk. Thirty pots of both clones were exposed during one-year period (September, 2002-August, 2003). Twenty inflorescences were taken from each clone twice a month in the morning, in order to estimate the frequency of mutations in stamen hairs. Results were compared to air pollution and climatic data measured next to the exposure site. KU-20 showed stamen-hair mutations greater than BNL 4430. Greatest mutation rates in KU-20 were observed in condition of high monthly mean of NO 2 and average peak concentrations of NO during the day, indicating that mutagenic effects originated from vehicular pollution. Clone KU-20 revealed to be more appropriate for biomonitoring purposes at the Park. - Clone KU-20 showed to be more appropriate than clone BNL 4430 to indicate vehicular pollution mutagenic risks in Trad-SHM assay

The aim of this research was to characterize the mutagenic potential of the pollutants in the water of the Paraíba do Sul river, in Tremembé city, São Paulo State, Brazil, analyzing chromosomal changes in the meristematic cells of Allium cepa, in the summer (April and winter (August of 2008. The bulbs were exposed for 72 h to the treatments: water from river, Hoagland solution (negative control and 15 µg/L from MMS – methyl methanesulfonate (positive control. In each treatment, three bulbs were exposed and for each bulb, five slides were prepared. For mitotic index (MI and micronucleus (MN frequency rate, a total of 2,000 cells per root/slide were analyzed and 100 cells for the chromosome aberrations (CA. In April, the pollutants induced a high mutagenic potential in the meristematic cells of Allium cepa, the frequency rate of MN, stickiness and CA from non-identified type were greater than the negative control. In August, the only significant change found was the chromosome bridges. There was no significant change for MI. These results indicate that the effluents which have varied sources are inducing harmful effects on the bioindicator, therefore, it is important to keep biomonitoring and adopting effluents control measures. The measures are important because these waters are used primarily for public supply and irrigation.

    Culturomics is a new postgenomics field that explores the microbial diversity of the human gut coupled with taxono-genomic strategy. Culturomics, and the microbiome science more generally, are anticipated to transform global health diagnostics and inform the ways in which gut microbial diversity contributes to human health and disease, and by extension, to personalized medicine. Using culturomics, we report in this study the description of strain CB1 T ( = CSUR P1334 = DSM 29075), a new species isolated from a stool specimen from a 37-year-old Brazilian woman. This description includes phenotypic characteristics and complete genome sequence and annotation. Strain CB1 T is a gram-negative aerobic and motile bacillus, exhibits neither catalase nor oxidase activities, and presents a 98.3% 16S rRNA sequence similarity with Pseudomonas putida. The 4,723,534 bp long genome contains 4239 protein-coding genes and 74 RNA genes, including 15 rRNA genes (5 16S rRNA, 4 23S rRNA, and 6 5S rRNA) and 59 tRNA genes. Strain CB1 T was named Pseudomonas massiliensis sp. nov. and classified into the family Pseudomonadaceae. This study demonstrates the usefulness of microbial culturomics in exploration of human microbiota in diverse geographies and offers new promise for incorporating new omics technologies for innovation in diagnostic medicine and global health.

    Full Text Available Giardia and Cryptosporidium have caused several outbreaks of gastroenteritis in humans associated with drinking water. Contaminated sewage effluents are recognized as a potential source of waterborne protozoa. Due to the lack of studies about the occurrence of these parasites in sewage samples in Brazil, we compared the efficiency of two procedures for concentrating cysts and oocysts in activated sludge samples of one sewage treatment plant. For this, the samples were submitted to i concentration by the ether clarification procedure (ECP and to ii purification by sucrose flotation method (SFM and aliquots of the pellets were examined by immunofluorescence. Giardia cysts were present in all samples (100.0%; n = 8 when using ECP and kit 1 reagents, while kit 2 resulted in six positive samples (85.7%; n = 7. As for SFM, cysts were detected in 75.0% and 100.0% of these samples (for kit 1 and 2, respectively. Regarding Cryptosporidium, two samples (25.0%; kit 1 and 28.5% for kit 2 were detected positive by using ECP, while for SFM, only one sample (examined by kit 1 was positive (12.5%. The results of the control trial revealed Giardia and Cryptosporidium recovery efficiency rates for ECP of 54.5% and 9.6%, while SFM was 10.5% and 3.2%, respectively. Considering the high concentration detected, a previous evaluation of the activated sludge before its application in agriculture is recommended and with some improvement, ECP would be an appropriate simple technique for protozoa detection in sewage samples.Giardia e Cryptosporidium causaram vários surtos epidêmicos de gastroenterite, associados à água potável.

    Full Text Available Cymothoa spinipalpa sp. nov. (Isopoda, Cymothoidae a buccal cavity parasite of the marine fish, Oligoplites saurus, is described on the basis of eight male specimens and one female. The fish hosts were captured in the coastal waters of Natal, Rio Grande do Norte State, Brazil. In the new species, the anterior margin of the cephalon is doubled ventrally over the bases of the antennae. In this respect, it resembles C. recifea Thatcher & Fonseca, 2005. It differs from that species, however, in being much smaller and having basal carinae on the pereopods 4 to 7 that are small and rounded (not large and pointed. Also, pleopods 2-4 lack the folds and pockets that are present in C. recifea. The new species can be distinguished from all known Cymothoa spp. by the mandibular palps which are entirely covered with small spines in adult males. The mancas of the new species resemble those of Cymothoa oestrum since they have elongate antennae but they are wider and have shorter uropods.Cymothoa spinipalpa sp. nov.

    The uranium-238, uranium-234 and radon content of spring waters of Aguas da Prata (SP) - Platina, Paiol, Villela, Sao Bento, Prata-Radioativa, Prata-Nova, Boi, Vitoria and Prata-Antiga - was found; the activity ratio AR ( 234 U/ 238 U) was applied to the geochemistry of local water sources. The uranium analysis procedure consisted of the following steps: adition of 232 U- 228 Th spike to the samples, coprecipitation with iron, iron extraction with organic solvent, separation on anion-exchange resin, extraction with TTA, deposition on stainless steel disc and determination of uranium content by alpha spectrometry. The uranium-238 content changed from 0,10 to 11,56 ppb (average value = 2,3 ppb). The higher values were observed for the waters circulating through sandstones and the lower through volcanic rocks. The inverse correlation (r sub(s) =-0,76) between pH and uranium-238 content confirmed the contribution of this factor on its solubility. The significative correlation r sub(s) = 0,76 between dissolved oxygen and uranium-238 content also confirmed the higher uranium on the more oxidizing zones. The AR changed from 2,84 to 11,68 (average value = 6). These values defined the regional aquifer systems as mineralized in uranium. The higher AR were observed for the deep groundwaters and the lower for the shallow one. Because the 238 U→ 234 Th decay, the 234 Th ejection to the solution was confirmed as the most important factor responsible for the extreme observed isotopic fractionation. (Author) [pt

    Full Text Available OBJETIVO: Analisar a associação entre a exposição à violência por parceiro íntimo (VPI contra a mulher com desajustes comportamentais e problemas escolares entre os filhos. MÉTODOS: Inquérito populacional participante do WHO Multicountry Study on Violence Against Women, com 790 mulheres que coabitam com filhos de cinco a 12 anos, residentes no Município de São Paulo, SP, e na Zona da Mata de Pernambuco. Foram realizados três modelos múltiplos para estimar a força da associação entre variáveis explanatórias de apoio social e comunitário, eventos de vida estressantes, fatores sociodemográficos e gravidade da VPI, entre outras. Os modelos incluíram três respectivos desfechos: número de problemas de comportamento; agressividade; e interrupção abandono ou repetência escolar. RESULTADOS: A exposição à VPI física e/ou sexual grave esteve associada à ocorrência de problemas escolares, de problemas de comportamento em geral e de comportamentos agressivos na análise de regressão logística univariada. A exposição à VPI grave manteve-se associada à ocorrência de três ou mais problemas de comportamento entre seus filhos, independentemente do transtorno mental comum, da baixa escolaridade, de a mãe (avó ter sido vítima de VPI física e do apoio social e comunitário nos modelos de regressão logística múltiplos. A VPI grave esteve associada ao comportamento agressivo e aos problemas escolares, depois do ajuste por outras variáveis sociodemográficas, entre outras. O estado de saúde mental materna constituiu-se em fator mediador da relação entre a exposição à VPI e os problemas de comportamento, sobretudo agressividade. CONCLUSÕES: A VPI grave afeta o comportamento dos filhos e deve ser incluída na assistência à saúde das crianças em idade escolar, por meio de intervenções conjuntas entre crianças e mães.

    Full Text Available Os movimentos de colônias silvestres da abelha melífera africanizada (Apis mellifera L. no Estado do Ceará, Brasil, foram investigados com o objetivo de compreender variações anuais em sua população. A chegada e a partida de colônias de abelhas africanizadas (AHB, no município semi-árido de Canindé e na úmida cidade litorânea de Fortaleza (separadas por 120 km, foram monitoradas semanalmente, de janeiro de 1999 a dezembro de 2001, e comparados com os dados pluviométricos de chuvas em ambas as áreas. Os resultados demonstraram que as abelhas africanizadas somente nidificaram no semi-árido durante a estação chuvosa e o abandonaram na estação seca, ao contrário do observado em Fortaleza. Apenas 5% das colônias permaneceram na área semi-árida por todo o ano, por causa dos ataques de formigas (Camponotus sp. e carência de néctar e água na estação seca. A maioria das colônias migrou para as áreas litorâneas onde o clima é mais ameno e muitas espécies vegetais florescem nesta época do ano. O excesso de chuvas provavelmente forçava as colônias africanizadas a migrarem de volta ao semi-árido durante a estação chuvosa. Conclui-se que o abandono e a migração são estratégias que permitem às abelhas africanizadas sobreviverem no semi-árido nordestino, em contraste com as raças européias que nunca conseguiram estabelecer populações silvestres na região.We investigated the annual movements of feral Africanized honey bee (Apis melliferaL. colonies in the state of Ceará, Brazil, aiming to understand seasonal variations in their population.

Os resultados sugerem que a organização dos serviços públicos de saúde em Campinas tem viabilizado em alguns aspectos a promoção da eqüidade na saúde.OBJECTIVE: To compare the health care received during pregnancy, delivery, and the puerperium by women belonging to two different per capita family income strata: less than 1 minimum wage, and 1 or more minimum wages. METHOD: This is a cross-sectional observational study that was carried out with a random sample of 248 female residents of the city of Campinas, in the state of São Paulo, Brasil, who had given birth between April 2001 and March 2002. Socio-demographic data, as well as information concerning maternal morbidity and health care during pregnancy, delivery, and the puerperium, were obtained through home interviews. The Kessner index, the Adequacy of Prenatal Care Utilization index, and an index proposed by the authors based on the recommendations of the Brazilian Department of Health were used to assess the adequacy of prenatal care. The minimum wage in Brazil at the time of the study was 180 reais (approximately 71.4 US dollars. RESULTS: The lower income group included a larger proportion of women with low schooling, as well as adolescents, black women, and single women. Prenatal care was provided by the public Unified Health System to 73.7% of the women in the lower income group, versus 33.3% in the higher income group. The women in the lower income group started attending prenatal care later and had fewer visits in all than higher-income women. However, some health care quality indicators, such as performance of routine laboratory tests and anti-HIV antibody testing, the proportion of cesarean sections, and the frequency of infant rooming-in, showed more favorable figures in the lower income group. Both groups received comparable counseling and had similar rates of clinical testing, post-delivery tubal sterilization

    The use of medicinal plants in the treatment of diseases has increased significantly in the last years, as has research concerning chemical characterization of these plants. In this study, inorganic constituents were determined in leaves and in extracts from three medicinal plant species of the Casearia genus (C. sylvestris, C. decandra and C. obliqua) collected in distinct regions of the Atlantic Forest, SP. The elemental compositions of the soils in which these plants were grown were also determined. Traditionally, these plants are used due to their antiinflammatory, antiacid, antiseptic and cicatrizing properties. The antiulcer and the antitumor activities of the Casearia genus and its capacity to neutralize snake and bee venoms, have also been scientifically confirmed. The analytical methodology used was neutron activation analysis. Long and short irradiation periods of the samples and the standards were carried out at IPEN's IEA-R1 nuclear research reactor. In the leaf K was found at the percentage levels, Ca, Cl, Mg and Na at mg g -1 levels and the elements Br, Fe, Mn, Rb and Zn at the μg g -1 levels. As, Co, Cr, Cs, La, Sb, Sc and Se at the ng g -1 levels. Results obtained in the extracts indicated that the same elements present in the leaves are also found in their extracts. The comparison between the inorganic composition of Casearia sylvestris leaves collected from three different regions of the Atlantic Forest showed that the elemental concentrations in the plants leaves varied depending on the place where they were grown. Different Casearia species cultivated in a same region presented similar elemental compositions. Based on these findings it can be concluded that the studies about the pharmacological effect of Casearia genus plants grown in different types of soil are of great importance. The quality of the obtained results was assured by the analyses of the certified reference materials NIST 1573a Tomato Leaves, NIST 1515 Apple Leaves, INCT-TL-1 Tea

    Full Text Available As fitofisionomias campestres e as plantas do estrato herbáceo-arbustivo têm sido pouco estudadas em todo o mundo e, pelo seu desconhecimento, poucos esforços têm sido empreendidos em sua conservação. Visando contribuir para preencher esta lacuna, efetuamos a caracterização florística e do espectro biológico das fisionomias campo sujo e campo limpo úmido em um remanescente de vegetação de Cerrado no Horto Florestal de Botucatu, SP. Registramos, no total, 210 espécies, sendo a maioria ervas (61%, seguidas de arbustos (17% e subarbustos (17%. Espécies arbóreas representam apenas 6% da riqueza da flora local. Apenas 12 espécies foram comuns às duas fisionomias, indicando alta especificidade de habitat (alta diversidade beta. O campo sujo apresentou maior riqueza de espécies e diversidade de formas de vida, mas o número de famílias foi maior no campo úmido. Entre as espécies observadas, seis estão ameaçadas de extinção no estado de SP e no Brasil: Evolvulus fuscus Meisn., Curtia tenuifolia (Aubl. Knobl., Camarea hirsuta A.St-Hil., Andropogon hypogynus Hack., Richardia stellaris (Cham. & Schltdl. Steud. e Xyris brevifolia Michx.

    Full Text Available Hemotrophic mycoplasmas and Bartonella species are important pathogens that circulate between cats and invertebrate hosts, occasionally causing diseases in humans. Nevertheless, there are few reports on occurrences of these agents in cats in Brazil. The present study aimed to detect the presence of hemoplasma and Bartonella DNA by means of PCR and sequencing. FIV antigens and anti-FeLV antibodies, were studied by using a commercial kit on blood and serum samples, respectively, among 46 cats that were sampled during a spaying/neutering campaign conducted in Jaboticabal, SP. Three (6.5% cats were positive for hemoplasmas: two (4.3% for 'Candidatus M. haemominutum' and one (2.2% for both M. haemofelis and 'Candidatus M. turicensis'. One of the two 'Candidatus M. haemominutum'-infected cats was also positive for FeLV antigens and showed antibodies for FIV. Two cats (4.3% were positive for B. henselae. One of them was also positive for FeLV antigens. Eight cats (17.4% were positive for FeLV, and just one (2.2% showed anti-FIV antibodies. Bartonella species and hemoplasmas associated with infection due to retroviruses can circulate among apparently healthy cats.Micoplasmas hemotróficos e espécies de Bartonella são importantes patógenos que circulam entre gatos e hospedeiros invertebrados, causando ocasionalmente doenças no homem.

    Full Text Available O estudo do comportamento alimentar tem despertado grande interesse por se tratar de um elemento importante para o sucesso de intervenções nutricionais. Considerando-se a complexidade do tema e as inúmeras influências a que está submetido, sugere-se que o aprofundamento de pesquisas sobre os determinantes do comportamento alimentar possibilite maior impacto nas ações de promoção de práticas alimentares saudáveis. A adoção cada vez mais freqüente de uma alimentação inadequada no Brasil e no mundo leva a um questionamento sobre o impacto das intervenções nutricionais tradicionalmente utilizadas em âmbito populacional. Diversas estratégias de educação nutricional são atualmente descritas na literatura; contudo, alcançar a motivação da população para uma mudança efetiva do padrão alimentar ainda é um dos grandes desafios para a saúde pública. A aplicação do modelo transteórico parece ter um papel promissor em relação à melhor compreensão da mudança de comportamento alimentar, almejada nas intervenções nutricionais. Estratégias que envolvam o direcionamento para cada estágio de mudança de comportamento, identificado segundo essa teoria, podem ser mais eficazes quanto à motivação dos indivíduos a adotar práticas alimentares mais saudáveis.The study of eating behavior has been much interest, as this is an essential element for the success of dietary interventions. In view of the complexity of the subject and the countless influences to which it is subject, it is suggested that an in-depth exploration of eating behavior determinants enhances the impact of programs promoting healthy dietary practices. Increasingly more frequent, the adoption of inadequate diets in Brazil and elsewhere in the world leads to questions about the impact of dietary interventions traditionally applied to population groups.

METHODS: Visual acuity measurements were performed by trained teachers using Snellen's chart. The children with VA <0.7 in one of the eyes were referred to an ophthalmic examination. The ophthalmic examination was considered gold standard to assess quality and cut-off point of the examinations performed by teachers. VA test was performed in 604 schoolchildren of state public schools (1,208 eyes. Analyses were based on examined eyes. We calculated sensitivity (S, specificity (E, positive predictive value (PPV, negative predictive value (NPV and likelihood rate (LR. We compared the means obtained by the teachers' examinations to means of the ophthalmologist's examinations. ROC curve was produced to evaluate whether VA lower than 0.7 is the best value for referral to an ophthalmic examination. RESULTS: VA means obtained by teachers and ophthalmologic examinations were 0.70 ± 0.16 and 0.88 ± 0.2 respectively. The difference between teachers' and ophthalmologists' examinations was 0.18 (p<0.0001. S, E, PPV, NPV e LR were: 82%, 40%, 27%, 89% and 1.37, respectively.

    The crude oil rheological properties are quite important in its transport and refining processes. They can affect the head losses and, thus, the pressure within a refining unit. These properties can be affected by the temperature and the chemical composition as well as by solvents added to the crude oil. The current work studied the rheological behaviour of both a crude oil from the Reconcavo Baiano (Brazil) and mixture of this crude oil with organic solvents (toluene and xylene). The solvent type and concentration effects on the rheological parameters, were studied. The Brookfield viscometer, model LDVD-II, was used. The results brought to light that the crude oil and the crude oil-solvent mixtures behaved, discretely, as thixotropic fluids. The model of Herschel-Bulkley for viscoplastic fluid was the best in fitting the experimental data for both crude oil and crude oil - solvent mixture. The toluene was found to be more efficient in reducing both the apparent viscosity and apparent yield stress of the crude oil than the xylene for a given concentration. The solvent concentration affects indirectly the rheological properties of the crude oil. (author)

    Full Text Available The only breeding record of Spartonoica maluroides (d'Orbigny & Lafresnaye, 1837 for Brazil is based on the observation of a fledgling in southern Rio Grande do Sul in January 1976. On 7 December 2005 we discovered a nest containing three nestlings at the southeastern end of Lagoa Pequena, municipality of Pelotas, Rio Grande do Sul. The nest was concealed at the base of a cavity in a Spartina densiflora (Poaceae tussock located at the edge of a saltmarsh. The nest was built of fine pieces of dead Scirpus olneyi (Cyperaceae and S. densiflora leaves firmly interlaced to the internal leaves of the tussock. Live leaves of S. densiflora lining the cavity comprised a substantial part of the nest's architecture, forming most of its upper lateral walls and roof. The lower section was more elaborate, resembling a deep cup and forming a distinct incubation chamber. Adults reached the nest's interior through an irregular apical opening amidst the leaves. The nest was 244 mm high and 140 mm wide. The incubation chamber had an external diameter of 138.5 mm, an internal diameter of 79.4 mm and was 86 mm deep. It was lined with fine leaves and white plant fibers. Nestlings were five to six days old. A total of 107 neossoptiles restricted to the capital, spinal and alar tracts were recorded in one nestling. The distribution of neossoptiles in the ocular region of S. maluroides forms a distinct pattern which can be typical of Furnariidae and related families. Two adults attended the nest, bringing small insects to the nestlings and removing fecal sacs. We recorded at least 74 visits to the nest during a ca. 6 h period during an afternoon. The average number of visits per hour was 12.8 ± 1.3. An adult bird spent on average 0.7 ± 0.56 minutes inside the nest attending nestlings. The nest remained unattended on average for 3.61 ± 3.13 minutes. The hour of the day had no influence on the amount of time spent by an adult in the nest or away from it. We returned to

The data came from measurements of diameters (DBH, total height and bole height of all Araucaria angustifolia trees from an Ombrophylous Mix Forest fragment of 15,24 ha situated in the Botanical Garden Campus of the UFPR, Curitiba-PR, Brazil. Thirteen  models were tested, including arithmetic, logarithmic and nonlinear  models, such as Chapman-Richards and Mitschertich or monomolecular adapted; the nonlinear models were fitted by the Levenberg-Marquart algorithm. The statistic criteria for selecting the best models were the graphic analysis of residuals, Standard error of estimate in percentage (Syx% and adjusted determination coefficient (R2 aj. The R2 aj were very low for all fitted models, characterizing an advanced and asymptotic stage of the species under study. The best equation for estimating ht was that one proposed by Stoffels & Van Soest, and for hf the Curtis equation in its logarithmic form, chosen due to its statistics values and easy utilization. The adjusted linear equation to estimate total height as a function of bole height presented R2 aj = 0.88 and Syx% = 5 %, characterizing a strong relationship between these two variables.Esta pesquisa teve como objetivos testar e selecionar os melhores modelos matemáticos para estimar

    Full Text Available The physical and physicochemical characteristics of blueberry (Vaccinium myrtillus fruits produced in Brazil were analyzed. Rheological properties were measured at 5, 25, 45 and 65 °C, on a stress controlled rheometer equipped with grooved a stainless-steel parallel-plate in a shear rate range of 0-300 s-1, with the objective of determining the influence of temperature on the rheological properties. The pseudoplastic behavior with yield stress was well described by the Ostwald-de-Waele (Power Law, Herschel-Bulkley (HB and Mizhari Berk models. The yield stress and behavior index decreased with the increase in the temperatures for 5, 25, and 45 °C whereas for the temperature of 65 °C the effects were the opposite exhibiting elevated values. The viscosity decreased with an increase in temperature, and the Arrhenius equation described adequately the effect of temperature on the apparent viscosity of the puree, in which the activation energy (Ea determined at a shear rate of 100 s-1 was 9.36 kJ.mol-1.As características físicas e físico-químicas do mirtilo (Vaccinium myrtillus produzido no Brasil foram analisadas. As propriedades reológicas foram medidas em 5, 25, 45 e 65 °C, em um reômetro de tensão controlada equipado com geometria rugosa de placas paralelas com taxa de deformação variando de 0-300 s-1 com o objetivo de verificação da influência da temperatura no comportamento do fluido. O comportamento pseudoplástico com tensão residual foi bem descrito pelos modelos de Ostwald-de-Waele (Lei da Potência, Herschel-Bulkley (HB e Mizhari Berk. A tensão residual diminuiu com o aumento da temperatura para 5, 25 e 45 °C, enquanto que para 65 °C os efeitos foram contrários, exibindo elevados valores. A viscosidade diminuiu com o aumento da temperatura e a equação de Arrhenius apresentou uma boa descrição do efeito da temperatura na viscosidade aparente do mirtilo, e a energia de ativação (Ea determinada para uma taxa de

    Full Text Available Um dos agentes mais empregados na supressão de áreas florestais no Estado de São Paulo é o fogo, por meio de queimadas que, quando fora de controle, podem converter-se em incêndios responsáveis pela destruição de extensos ecossistemas. Na Bacia do Rio Corumbataí, SP, os incêndios são um dos causadores de fragmentação e degradação da cobertura florestal. Nesse contexto, este trabalho objetivou a realização do mapeamento de risco de incêndios florestais na Bacia do Rio Corumbataí, utilizando-se a avaliação multicriterial (Método da Média Ponderada Ordenada em um Sistema de Informações Geográficas. Os fatores importantes do estudo foram: declividade do terreno, face de exposição ao sol, pluviosidade, proximidade da malha viária, proximidade dos centros urbanos, proximidade da rede hidrográfica, vizinhança dos fragmentos e face de exposição aos ventos. A combinação dos mapas de fatores resultou no mapa de risco regional da bacia. Para a confecção do mapa de risco em nível de fragmento, determinou-se o risco associado a cada fragmento, a partir da análise de uma faixa de 30 m em seu entorno. O risco foi reclassificado em três classes: baixo, médio e alto. Com base no mapa final, verificou-se que: aproximadamente 20% dos fragmentos de mata nativa pertencem à classe de risco alto, 55% à classe de risco médio e 25% à classe de risco baixo. Nas condições atuais de uso e cobertura do solo, bem como de manejo das áreas agrícolas e pastagens, os remanescentes florestais da Bacia do Rio Corumbataí estão sob séria ameaça de degradação por incêndios florestais.Fire is one of the agents most used in the suppression of forest areas in the State of São Paulo, Brazil, and, when out of control, it can be responsible for the destruction of extensive ecosystems.

    Full Text Available Brazilian Spotted Fever (BSF is a lethal rickettsiosis in humans caused by the bacteria Rickettsia rickettsii, and is endemic in some areas of Brazil. Horses and dogs are part of the disease's life cycle and they may also serve as sentinel animals in epidemiological studies. The first human BSF case in the State of Paraná was reported in 2005. The present study was conducted in the municipality of Almirante Tamandaré, where no previous case of BSF was reported. Serum samples were collected from 71 horses and 20 dogs from nine properties in the area. Ticks were also collected from these animals. All farmers completed a questionnaire about their knowledge of BSF and animal health management. Serum samples were analyzed by indirect immunofluorescent-antibody assay (IFA using R. rickettsii and R. parkeri as antigens. Ticks were analyzed by PCR for Rickettsia sp., and all of them were PCR-negative. Six horses (8.45% and 4 dogs (20% were identified as seropositive. Farmers were not aware of the correlation between the presence of ticks and risk of BSF. Although a non-endemic area, Almirante Tamandaré is a vulnerable environment for BSF and effective tick control measures are required.A Febre Maculosa Brasileira (FMB é uma riquetsiose letal para humanos, causada pela bactéria Rickettsia rickettsii, e é endêmica em algumas regiões brasileiras. Equinos e cães podem participar do ciclo da doença e podem também servir como sentinelas em estudos epidemiológicos. O primeiro caso humano relatado no Estado do Paraná ocorreu em 2005. O presente estudo foi realizado no município de Almirante Tamandaré, região onde não há relatos de casos de FMB. Foram coletadas amostras de sangue de 71 cavalos e 20 cães em nove propriedades rurais na região. Carrapatos também foram colhidos dos animais. Todos os proprietários responderam a um questionário sobre o manejo sanitário dos animais e o conhecimento a respeito da FMB. As amostras de soro foram

    Full Text Available O planejamento regional de agroecossistemas é um componente fundamental para a sustentabilidade da atividade agrícola, devendo considerar a realidade biofísica e socioeconômica. A agropecuária cumpre importante papel na região de São Carlos, SP, porém esta localiza-se em grande parte numa área de preservação ambiental. Este trabalho visou delimitar a Zona Agroecológica dessa região e diagnosticar seus agroecossistemas por meio de informações edafoclimáticas e socioeconômicas. A delimitação foi baseada no clima, geomorfologia e divisão administrativa. Da área delimitada estudou-se o clima, pedologia, uso da terra, estrutura fundiária e o manejo dos agroecossistemas. A Zona delimitada ocupa 286.824,08 ha, e é composta pelos municípios de Analândia, Itirapina, Santa Maria da Serra, São Carlos, São Pedro e Torrinha. Há potencial para a atividade agrícola, ocorrendo principalmente solos arenosos e de baixa fertilidade. Pastagens e cana-de-açúcar são os usos predominantes; a distribuição da posse da terra é desigual, e existe risco de degradação ambiental, pois não se empregam práticas compatíveis com as características naturais. Recomenda-se o uso de práticas que maximizem a conservação do solo, sua correção, e o aproveitamento de seus nutrientes, assim como o cultivo de espécies adaptadas a solos arenosos, que sejam pouco exigentes em fertilidade e resistentes a estresse hídrico.Regional planning of agroecosystems is a key component in the sustainability of agriculture and it should consider the biophysical and socio-economic reality.

    Full Text Available A desnutrição é ainda um problema de saúde pública no Brasil, apesar do declínio de sua prevalência mostrado em estudos nacionais. Contudo, dada a abrangência destes levantamentos, a situação em áreas de pobreza pode ser subestimada. O objetivo deste trabalho foi avaliar a desnutrição em áreas de pobreza do município de Campinas, SP, identificadas segundo os critérios de renda familiar, condições de construção da moradia e contigüidade, de acordo com o censo de 1991. A amostra foi composta de 125 crianças de 0 a 24 meses de idade e suas mães, com coleta de dados antropométricos (peso e altura e socioeconômicos. Os resultados mostraram uma prevalência de 7,2% de desnutrição infantil, muito semelhante à média de 7,4% observada para a mesma faixa etária em levantamento nacional feito em 1989. Em relação ao estado nutricional das mães, os resultados mostraram que 27,3% apresentaram Índice de Massa Corporal superior a 25kg/m². A fim de promover o declínio da prevalência de desnutrição, as ações de saúde devem considerar a importância do problema em grupos socioeconômicos especiais, como os de baixo poder aquisitivo, desenvolvendo um sistema de vigilância alimentar e nutricional capaz de atuar em regiões onde as ações tradicionais parecem ser menos eficientes.Malnutrition is one of the major public health problems in Brazil, although recent data show a progressive decrease in its prevalence. However, the validity of national surveys can underestimate the magnitude of malnutrition in poverty areas. The purpose of this study was to evaluate malnutrition in poverty areas of Campinas, SP, and efforts were made to locate those urban areas, considering families income, building conditions, and geographic contiguity according to 1991 census. During the study period, a total of 125 children aged 0 to 24 months and their mothers were interviewed, and anthropometric and socioeconomic data were collected. Results

    Full Text Available O homo sapiens vai às compras com uma mente moldada em um ambiente de caçadores e coletores. O estudo da biologia evolutiva não se restringe às características físicas selecionadas por meio de pressões ambientais e sua contribuição para a sobrevivência e reprodução de organismos. Características comportamentais também são selecionadas e há pouca ou nenhuma discordância a esse respeito quando o não se trata de comportamentos da espécie homo sapiens. Módulos mentais selecionados ao longo de um passado ancestral e não necessariamente adaptados ao mundo moderno influenciam, ainda que não percebidos, as decisões de seres humanos em ambientes de compra. Módulos mentais distintos como a atração de parceiros ou flerte, sua manutenção e cuidado com a prole, a reputação e status perante o grupo e a resposta frente ameaças à sobrevivência, foram selecionados, tal qual características físicas, por sua capacidade de resposta aos problemas recorrentes nesse passado ancestral. Vieses cognitivos, sintomas da irracionalidade que para os economistas comportamentais, desafiam os fundamentos da economia clássica, são, para a Psicologia Evolucionista, o resultado de uma racionalidade profunda selecionada em um ambiente ancestral para a resolução de problemas recorrentes e não perfeitamente adaptada ao mundo atual. Os vieses de hoje são resultados da racionalidade que no passado promoveu adaptação e sobrevivência. A Psicologia Evolucionista é um campo de estudo que visa unificar os domínios da Teoria da Evolução e da Psicologia Cognitiva procurando responder como um comportamento particular, cognição, emoção e/ou percepção constituiu uma solução funcional para um problema adaptativo no passado evolutivo. A incorporação de princípios da Psicologia Evolucionista ao estudo do Comportamento do Consumidor oferece uma potencial meta teoria capaz de unificar os diversos subcampos da psicologia, contribuindo para

Em cada época de semeadura, efetuaram-se avaliações de rendimento de grãos e altura de plantas. A disponibilidade hídrica do solo para a cultura foi caracterizada através de balanço hídrico decendial, considerando 125mm como a capacidade máxima de retenção de água no solo. Os resultados indicaram como a melhor faixa de semeadura, independente de cultivar, o período compreendido entre o terceiro decêndio de março e o primeiro decêndio de abril. Indicaram, também, que os períodos extremos estudados são pouco favoráveis à semeadura do trigo na região. O cultivar CNT-8 foi o mais produtivo, de maior porte de planta, independente do ano e da época de semeadura. Entre os anos em estudo, destacou-se o de 1979, cujos cultivares de trigo exibiram as maiores produções de grãos, em vista das condições climáticas favoráveis para a cultura.This paper presents the behaviour of three wheat cultivara (CNT 8, IAC 17 and BH-1146 at eight seeding times (the first seeding time was from 1st to 10th of March and the last one from to 20th to 30th of May in experiments carried out at Canadá Farm, Assis, State of Sáo Paulo, Brazil, in the period 1978-1982. Grain yield and plant heigth were evaluated for each seeding time, in each experiment. Soil water availability was obtained by water balances taken at each ten days considering 125mm as the soil water retention capacity. The results showed that the seeding time from 20th of March to 10th of April was the best considering grain yield, independently of the cultivar. The results also indicated that the others studied seeding times were not favourable to seed wheat in this region. The wheat cultivar CNT 8 was the most

    Full Text Available Realizou-se levantamento da prevalência de dislipidemias e alguns fatores de risco (hipertensão, obesidade e alcoolismo, em uma população típica da periferia do Município de São Paulo, SP (Brasil. A prevalência de um ou mais fatores de risco foi maior do que 50% em todos os grupos etários. No que concerne às dislipidemias propriamente ditas, foi de aproximadamente 49%, 58% e 57% nos grupos etários de 20 a 39 anos, 40 a 59 anos e 60 anos e mais, respectivamente. A dislipidemia mais freqüente foi devido a baixos níveis de HDL-colesterol, principalmente nos mais jovens, entre 29 e 39 anos. Nos outros dois grupos etários houve prevalência maior de "outras dislipidemias". A obesidade isolada ou associada foi o fator de risco mais relevante na população estudada. Levanta-se a hipótese de que as dislipidemias podem constituir-se em grave problema de Saúde Pública nas populações periféricas da cidade de São Paulo.A survey of the prevalence of lipemic disorders and some risk factors associated with them (obesity, hypertension and alcoholism, in a representative sample of the population of 20 years of age and over in a locality typical of the peripheral zone of the Greater S.

Estas relações se repetem na paisagem da microbacia com características de solo, relevo e litologia semelhantes, permitindo sua extrapolação para outras áreas, contribuindo para futuros levantamentos detalhados de solos que possam vir a ser realizados na região.The relationships between soil, geology and geomorphic surface were studied in the Marins basin of Piracicaba, S.P., Brazil. Soils, parent material, geology and geomorphic surfaces were mapped. Two transects were studied to verify the lateral variation of the soils. Geology derives from Neo-Cenozoic superficial deposits of a loamy sand texture, sandstone belonging to the Piramboia Formation of the São Bento group, with siltstones and shales belonging to the Corumbatai Formation of the Passa Dois group, and colluvial and alluvial sediments. Five geomorphic surfaces were identified. The relationships between soil, parent material, geology and geomorphic surfaces were performed cross-referencing the different maps. These relations were analyzed by comparision to an "uniformity index", specialy developed to verify the inter-relation uniformity. Ten soil units were identified (Oxisol, Ultisol and Inceptisol orders. The Oxisol is related to the neocenozoic cover and surface I, were the relief is almost flat. The Ultisol, with a predominance of a sandy loam texture, is related to the Pirambóia formation sandstone and to surfaces II and III, with gentle slopes. The Incepstisol, with a clayey texture, are associated to the Corumbataí formation siltstone and silex, with IV and V surfaces (ondulating relief. The Incepitsols of varied textures are related to alluvium and colluvium deposits.The relation that exists between the soils and the geomorphic surfaces is represented by the tendency that, the older and more stable the surface

    Full Text Available OBJETIVOS: Estudar o comportamento de estudantes de medicina em relação ao trânsito, comparando os padrões atuais com aqueles observados em estudo realizado anteriormente na mesma instituição. MÉTODOS: Foram aplicados questionários padronizados em uma amostra de estudantes regularmente matriculados no curso médico da Faculdade de Medicina de Ribeirão Preto, objetivando coletar informações demográficas, socioeconômicas e referentes ao comportamento no trânsito e envolvimento em acidentes. Esses resultados foram comparados com os obtidos em investigação semelhante, realizada em 1997. RESULTADOS: Foram estudados 354 alunos em 2008 e 377 em 1997. Do total, 431 (59% já haviam dirigido logo após a ingestão de álcool, sendo que, desses, 21,5% em condições de intensa alcoolização. Participação em rachas foi referida por 10,5% dos participantes, com diferença marcante entre os sexos (12,5% entre homens e 3,4% em mulheres. Envolvimento em acidentes com vítimas, fatais ou não, foi referido por 19,2% dos participantes. Esses percentuais atingiram 31,1% entre os que já dirigiram intensamente alcoolizados e 42,9% entre os que participaram de rachas. O estudo de 2008 evidenciou maior uso de capacete e de cinto de segurança em meio urbano e redução de uso de bebidas alcoólicas antes de dirigir. Por outro lado, mostrou redução de respeito contínuo à sinalização de semáforos. CONCLUSÃO: Comportamentos de risco no trânsito fazem-se presentes com elevada frequência entre os participantes, estando diretamente relacionados com o envolvimento em acidentes que provocam vítimas. Visto ser essa uma parcela populacional diferenciada, com conhecimento e contato direto com as consequências desses acidentes, esperar-se-ia uma menor presença de comportamentos de elevado risco. As informações oriundas desse trabalho devem conduzir a uma reflexão por parte da comunidade acadêmica com vistas à introdução de programas

    Full Text Available RESUMO Objetivo Este estudo investigou o engajamento de adolescentes brasileiros em comportamentos de risco (uso de substâncias, comportamento sexual de risco, comportamento antissocial e comportamento suicida, buscando identificar os fatores de risco e proteção pessoais e contextuais mais associados com esses comportamentos. Métodos Participaram 1.332 adolescentes de 12 a 19 anos (M = 15,68; DP = 1,60, de ambos os sexos. Resultados O engajamento em comportamentos de risco variou em função da idade e do sexo, e o uso de substâncias foi o tipo de comportamento de risco mais prevalente entre os que foram investigados. Os fatores significativamente associados à adoção desses comportamentos foram violência intra- e extrafamiliar, ter amigos próximos ou familiares que usam drogas, eventos estressores e elevado nível de autoeficácia; enquanto os fatores que se mostraram protetores foram elevado nível de autoestima, expectativas positivas quanto ao futuro e percepção de positividade nas relações com família, escola, religião e comunidade. Conclusão O estudo permitiu identificar algumas características da manifestação de comportamentos de risco na adolescência, com destaque para a prevalência mais alta do uso de substâncias e a coocorrência de diferentes tipos de comportamentos de risco. Dentre os fatores de risco mais associados com o engajamento em comportamentos de risco, destacaram-se a presença de eventos estressores ao longo da vida e a proximidade com amigos que usam drogas. A partir disso, sugere-se investir na minimização de fatores de risco e na potencialização de fatores protetivos para a promoção do desenvolvimento saudável durante a adolescência.

METHOD: 119 participants were randomly assigned to either a standard or a standard plus "thought mapping" intervention, and re-interviewed 2 and 8 weeks after intake using standardized data collection instruments. Intervention effects were examined using generalized estimated equation model. RESULTS: Significant increases in AIDS knowledge and condom use were observed in the experimental group, as well as significant changes in the subscores for sexual and drug risks. The experimental intervention was less successful in decreasing mean days of cocaine use when compared to the standard. CONCLUSION: Although not robust, the findings nevertheless suggest that components of the experimental thought-mapping model might be useful in combination with other approaches.OBJETIVOS: Comparar as mudanças em conhecimento sobre AIDS e comportamentos de risco em usuários de cocaína brasileiros submetidos a uma intervenção experimental. MÉTODO: 119 sujeitos foram aleatoriamente designados para uma intervenção padrão ou uma intervenção padrão adicionada a um "mapa cognitivo", e re-entrevistados duas e oito semanas após admissão no estudo, utilizando-se instrumentos de coleta padronizados. Os efeitos da intervenção foram examinados utilizando modelo de equações de estimação generalizadas. RESULTADOS: Foram observados aumentos significativos no conhecimento sobre AIDS e uso de preservativos no grupo experimental, bem como modificações significativas nos subescores para risco sexual e uso de drogas. A intervenção experimental teve menos sucesso em diminuir dias de uso de cocaína quando comparada com a intervenção padrão. CONCLUSÃO: Apesar de não serem robustos, os achados sugerem que os componentes do modelo de mapa cognitivo experimentados poderiam ser úteis em combinação com outras abordagens.

    Epidemiological studies on amebiasis have been reassessed since Entamoeba histolytica and E. dispar were first recognized as distinct species. Because the morphological similarity of these species renders microscopic diagnosis unreliable, additional tools are required to discriminate between Entamoeba species. The objectives of our study were to compare microscopy with ELISA kit (IVD®) results, to diagnose E. histolytica infection, and to determine the prevalence of amebiasis in a sample of students from southeastern Brazil. In this study, diagnosis was based on microscopy due to its capacity for revealing potential cysts/trophozoites and on two commercial kits for antigen detection in stool samples. For 1,403 samples collected from students aged 6 to 14 years who were living in Divinópolis, Minas Gerais, Brazil, microscopy underestimated the number of individuals infected with E. histolytica/E. dispar (5.7% prevalence) compared with the ELISA kit (IVD®)-based diagnoses (15.7% for E. histolytica/E. dispar). A comparison of the ELISA (IVD®) and light microscopy results returned a 20% sensitivity, 97% specificity, low positive predictive value, and high negative predictive value for microscopy. An ELISA kit (TechLab®) that was specific for E. histolytica detected a 3.1% (43/1403) prevalence for E. histolytica infection. The ELISA kit (IVD®) can be used as an alternative screening tool. The high prevalence of E. histolytica infection detected in this study warrants the implementation of actions directed toward health promotion and preventive measures.

    The industry of leather manufacture generates large quantities of solid leather waste with characteristics of high-polluting and hazardous conditions. Among these wastes, stands out the wet blue leather (chromed leather scraps), and the tanning sludge and secondary sludge generated in the processes of effluents treatment. These wastes contain Cr(III), which, under oxidizing conditions, can turn into Cr (VI), which is highly toxic. However, these wastes are a potential source of chromium oxide (traditional industrial pigment), which could be used by the glass and ceramic enamel industries. In this study, a preliminary characterization of a chromium sludge from the industrial district of Franca-SP was conducted. X-ray diffraction (XRD), chemical (XRF) and thermal (DTA / TG) analyses were used to determine the physical and chemical characteristics of this solid waste. The potential of using this material as an available and cheap pigment for the manufacture of enamels and glass is discussed. (author)

    Full Text Available Em termos gerais, operações estabelecedoras podem ser definidas como eventos ambientais que alteram a efetividade reforçadora de um estímulo, assim como evocam todo comportamento que, no passado, foi seguido por tal estímulo. O conceito parece descrever, em termos comportamentais, o que é usualmente chamado de motivação. O presente artigo pretende apresentar de uma forma didática o desenvolvimento teórico do conceito e seu status na Análise Experimental e Aplicada do Comportamento.

    Full Text Available The occurrence of the enteroparasites was verified in 279 children (0 to 6 years of four municipal day cares of Botucatu/SP. Three samples of each child's feces were collected and processed by the methods of Hoffman-Pons-Janner, Faust and Ritchie and subsequent coloration of the fecal smear by the methods of Auramina-O and Ziehl-Neelsen modified for diagnosis of Cryptosporidium sp. and Graham method for diagnosis of Enterobius vermicularis. Of the analyzed children we verified a prevalence of intestinal parasitism in 53.40%, and the most frequent parasite was Giardia duodenalis (26.88%. Significant association was verified among enteroparasitosis, family income, maternal education and age; the lowest enteroparasite frequency occurred in children of families with larger income and higher education. It was observed that G. duodenalis is more prevalent in children from 0 to 4 years and E. vermicularis is more frequent in children between three and four years old. The high enteroparasite prevalence in day cares suggests complex structure in its epidemiology, where factors beyond sanitation should be considered.Verificou-se a prevalência dos enteroparasitas em 279 crianças (0 a 6 anos de quatro creches municipais de Botucatu/SP.

To reach that target, field studies were made to qualify the geotechnical parameters of the rocky mass, in the axis area open galleries. It was also used in situ deformability and stress test results performed in those galleries, that were reinterpreted for a better adaptation of the mass values. The knowledge of the mass inherent characteristics together with the laboratories test results, allowed for the geomechanical classification applications in several different gallery sectors. The geomechanical data obtained allowed through mathematical expressions, to reach the rocky mass values correlations of interest to the work (deformability and strength), that could be compared to the in situ test results. That analysis permitted, besides the classification critical system evaluation, the geomechanical characterization of the rocky mass, focusing its ability to the dam arch construction. (author)

    The city of Limeira is located in the state of Sao Paulo, Brazil and has the second largest economy and demographic growth of the state. It comprises an expressive economy with industries in several productive sectors. The source of the Graminha and Aguas da Serra streams is located within the Limeira urban zone. The streams cross part of the rural zone and unite by draining into the Piracicaba River. It is possible that these basins suffer or have already suffered the impacts of environmental pollution caused by anthropogenic factors. Since the city has galvanization industries for the production of precious and semi-precious jewels as well as imitation jewelry, the concentration descriptions and interpretations of heavy metals in waters and sediments indicate anthropogenic influence and the dumping of these compounds into the Piracicaba River. The Synchrotron Radiation Total Reflection X-Ray Fluorescence (SR-TXRF) was used for determining the metals. All measurements were performed using a white beam of synchrotron radiation for excitation and a Ge hyperpure detector. Detection limits for water samples were 0.04 μg L -1 and in sediment samples 0.03 μg g -1 for Cu and Zn elements. In the water samples, concentrations higher than permissible as established by the Brazilian legislation (CONAMA) for Al, Fe, Zn, Cr, Ni, Cu and Pb, were observed. For sediment samples, values higher than quality reference values defined by the Brazilian legislation (CETESB) were verified for Cr, Zn, Cu, Ni and Pb

    Tomato plants (Lycopersicon esculentum) are highly susceptible to phytopathogen attack. The resulting intensive application of pesticides on tomato crops can affect the environment and health of humans and animals. The objective of this study was to select potential biocontrol agents among actinobacteria from tomato plants, in a search for alternative phytopathogen control. We evaluated 70 endophytic actinobacteria isolated from tomato plants in southern Brazil, testing their antimicrobial activity, siderophore production, indoleacetic acid production, and phosphate solubility. The actinomycete isolate with the highest antimicrobial potential was selected using the agar-well diffusion method, in order to optimize conditions for the production of compounds with antimicrobial activity. For this study, six growth media (starch casein-SC, ISP2, Bennett's, Sahin, Czapek-Dox, and TSB), three temperatures (25 degrees C, 30 degrees C, and 35 degrees C) and different pH were tested. Of the actinobacteria tested, 88.6% showed antimicrobial activity against at least one phytopathogen, 72.1% showed a positive reaction for indoleacetic acid production, 86.8% produced siderophores and 16.2% showed a positive reaction for phosphate solubility. Isolate R18(6) was selected due to its antagonistic activity against all phytopathogenic microorganisms tested in this study. The best conditions for production were observed in the SC medium, at 30 degrees C and pH 7.0. The isolate R18(6) showed close biochemical and genetic similarity to Streptomyces pluricolorescens.

    Full Text Available OBJETIVO: Alertar os pediatras sobre a alta prevalência da prática de bullying entre estudantes, conscientizando-os da importância de sua atuação na prevenção, diagnóstico e tratamento dos possíveis danos à saúde e ao desenvolvimento de crianças e adolescentes, além da necessidade em orientar as famílias e a sociedade para o enfrentamento da forma mais freqüente de violência juvenil. FONTE DE DADOS: Foram acessados bancos de dados bibliográficos e páginas de relevância na Internet, identificando-se artigos e textos recentes sobre o tema. SÍNTESE DOS DADOS: O comportamento agressivo entre estudantes é um problema universal, tradicionalmente admitido como natural e freqüentemente ignorado ou não valorizado pelos adultos. Estudos realizados nas 2 últimas décadas demonstraram que a sua prática pode ter conseqüências negativas imediatas e tardias para todas as crianças e adolescentes direta ou indiretamente envolvidos. A adoção de programas preventivos continuados em escolas de educação infantil e de ensino fundamental tem demonstrado ser uma das medidas mais efetivas na prevenção do consumo de álcool e drogas e na redução da violência social. CONCLUSÃO: A prevenção do bullying entre estudantes constitui-se em uma necessária medida de saúde pública, capaz de possibilitar o pleno desenvolvimento de crianças e adolescentes, habilitando-os a uma convivência social sadia e segura.OBJECTIVE: To warn pediatricians about the high prevalence of bullying among students, to raise their awareness about the importance of their action in the prevention, diagnosis, and treatment of possible damage to children's health and development, and about the necessity to instruct families and society on how to face the most frequent form of youth violence. SOURCE OF DATA: Bibliographic databases and relevant Internet sites were searched for recent articles and texts about the theme. SUMMARY OF THE FINDINGS: Aggressive behavior

    Full Text Available The objective of this work was to compare the meiotic behavior and pollen grain viability of three species of Crotalaria. Slides for meiotic analysis were prepared by the air-drying technique. Pollen grain viability was measured by three staining procedures (Alexander's solution, tetrazolium chloride and fluorescein diacetate and in vitro germination in a sucrose solution. Eight bivalents were observed, confirming previous reports on populations from other regions of Brazil, as well as from other countries. All species showed abnormal meiotic behavior as follows: in Crotalaria micans, cytomixis and abnormal chromosome pairing in diakinesis; in C. spectabilis, abnormal chromosome pairing in diplotene; in C. zanzibarica, shrunk nuclei in leptotene and zygotene. Pollen grains of all three species show low viability, which may be associated with the irregularities of the meiotic behavior.O objetivo deste trabalho foi comparar o comportamento meiótico e a viabilidade dos grãos de pólen de três espécies de Crotalaria. A análise meiótica foi realizada por meio da técnica de secagem ao ar. A viabilidade dos grãos de pólen foi avaliada por testes de coloração (corante de Alexander, cloreto de tetrazólio e diacetato de fluoresceína e por teste de germinação em solução de sacarose. Foram observados oito bivalentes, confirmando relatos prévios em populações de outras regiões do Brasil e de outros países. As três espécies apresentaram comportamento meiótico irregular: em Crotalaria micans, citomixia e pareamento irregular na diacinese; em C. spectabilis, pareamento irregular no diplóteno; e em C. zanzibarica, núcleo fortemente condensado nas fases de leptóteno e zigóteno. A viabilidade dos grãos de pólen das três espécies é baixa, o que pode estar associado às irregularidades do comportamento meiótico.

  11. Seasonal variations in water quality of an oxbow lake in response to multiple short-time pulses of flooding (Jataí Ecological Station--Mogi-Guaçu River, Luiz Antonio, SP-Brazil).

    Mogi-Guaçu River is a six-order floodplain river in the upper Paraná River Basin, Southern Brazil. Its yearly discharge varies from a minimum of 100 m3.s-1 to a maximum of 600 m3.s-1. Diogo Lake is a shallow lake located at its floodplain within the Jataí Ecological Station (Luiz Antonio, São Paulo State) and is connected throughout the year to the river through a narrow and shallow channel. The main finding of this study is that the river hidrology controls the annual variations in lake hydrochemistry through a series of hydraulic effects related to oscillations in river discharge. Lake water quality is a resultant of differential contribution from local and regional watersheds. During the low water period, lake water quality is determined by inputs from Cafundó Creek, which drains the local watershed into the lake. Raising the river level during the rain season results in the damming of lake and culminates with the entrance of river waters into the plain. The geochemistry of waters in this system is determined by weathering of sandstones with basalt intrusions. Waters are acidic (river pH = 6.00 to 7.02 and stream-lake pH = 5.15 to 6.7) and dominant cations are Na+ and K+. Major anions are almost exclusively represented by bicarbonate and an unknown concentration of organic acid anions. The overall ionic load of these soft waters in the system is therefore very low.

    This work presents an application of Failure Mode Effect Analysis (FMEA) to the process of identification of environmental aspects and impacts as a part of implementation and maintenance of an Environmental Management System (EMS) in accordance with the NBR ISO 14001 standard. Also, it can contribute, as a complement, to the evaluation and improvement of safety of the installation focused. The study was applied to the Nuclear Fuel Center (CCN) of Nuclear and Energy Research Institute (IPEN), situated at the Campus of University of Sao Paulo, Brazil. The CCN facility has the objective of promoting scientific research and of producing nuclear fuel elements for the IEA-R1 Research Reactor. To identify the environmental aspects of the facility activities, products, and services, a systematic data collection was carried out by means of personal interviews, documents, reports and operation data records consulting. Furthermore, the processes and their interactions, failure modes, besides their causes and effects to the environment, were identified. As a result of a careful evaluation of these causes it was possible to identify and to classify the major potential environmental impacts, in order to set up and put in practice an Environmental Management System for the installation under study. The results have demonstrated the validity of the FMEA application to nuclear facility processes, identifying environmental aspects and impacts, whose controls are critical to achieve compliance with the environmental requirements of the Integrated Management System of IPEN. It was demonstrated that the methodology used in this work is a powerful management tool for resolving issues related to the conformity with applicable regulatory and legal requirements of the Brazilian Nuclear Energy Commission (CNEN) and the Brazilian Institute of Environment (IBAMA).

    The wind energy is an abundant source of renewable energy, clean and available almost everywhere. For its use, studies are needed to adequately describe its intensity for statistical methods and design for wind turbines. The objective is to structure the mathematical methods used to conduct a general description of the wind, to establish a description of the wind regime using the parameters described using the Weibull function and the analytical model of power from a wind turbine, as well as applications of these methods show. This work was developed at Rural Empowerment Lab of FCA/UNESP in Botucatu-SP. For the application of methods were utilized measurements of wind speed and direction, between 2004 and 2005, obtained by anemometer RM Young Wind Monitor-Campbell. As a result, they estimated the wind behavior and distribution of wind in the region, with 78 kWh of energy production, relatively low potential to supply a small house. Moreover, this energy could possibly be applied in ambient illumination, power supply for electric fences and irrigation of vegetables. (author)

    Full Text Available A metacercária de Neascus sp., causadora da doença dos pontos pretos, é descrita em espécimes de Geophagus brasiliensis coletados no Brasil. Entre março e maio de 2006, foram capturados 33 espécimes de G. brasiliensis, coletados com o auxílio de vara e anzol no Rio do Peixe, Monte Verde, município de Juiz de Fora, Estado de Minas Gerias. Dos 33 espécimes examinados, 30 (90,9% apresentaram-se parasitados por metacercárias causadoras dos pontos pretos, com intensidade média de infecção de 15,6 ± 16,1 (1 – 75. Foi observada correlação significativa entre o comprimento total de G. brasiliensis e a abundância parasitária (r = 0,459; P Neascus-type metacercariae, which cause the black spot disease, are described in specimens collected from 33 samples of Geophagus brasiliensis from the Peixe river, in Monte Verde, Juiz de Fora, state of Minas Gerais, Brazil, during March and May 2006. The main morphological features of these metacercariae are: genital primordia composed of three cell masses located in the hind body, and a median dorsal vessel of the reserve bladder around the acetabulum. Thirty fish specimens (90.9% were parasitized by metacercariae, with mean infection intensity of 15.6 ± 16.1 (1-75. Also, a positive correlation was detected between G. brasiliensis total length and the parasite abundance (r = 0.459; p < 0.01.
