    2002-02-01

    This work deals with radioactive traces measurements in foodstuffs produced at the State of Parana, with large export rate and also of nutritious products of some regional trading companies. The measured foods were: sulfite treated sugar, tea, mint candy, soy in grain, soy crumb, gross soy oil, gum free oil and commercial refined soy oil. Six samples of each lot of the analyzed material were prepared, which represent a sampling with 90% of confidence. The samples were sealed in Marinelli beaker of 2.1 L completely filled and kept during 40 days until secular equilibrium was achieved. The counting time for each measure was of 48 hours. Measurements were carried out by gamma-ray spectrometry employing a HPGe detector with 10% of relative efficiency, coupled to standard nuclear electronics and a 8 l multichannel card. The acquisition of the data was accomplished with the software Maestro TM , version 3.2. The energy resolution of the 137 Cs 661.62 keV gamma line was 1.75 keV. The larger intensity gamma lines observed in the spectra were from the following radionuclides: 228 Ac, 208 Tl, 212 Pb of the 232 Th series, 214 Bi and 214 Pb from the 238 U series, 227 Ac from the 235 U series and 40 K. Activities and lower level of detection limits were calculated according to the International Agency of Atomic Energy norms.The detector efficiency was measured using a 152 Eu certified source and IAEA-375 and IAEA-326 certified reference materials. For most of the radionuclides it was possible only the measurement of the minimum activity detectable in the foodstuffs. Self-attenuation corrections were accomplished with support literature results. The most important activity observed was that of 40 K, whose value measured for soy in natura was 745.0 + - 9 .1 Bq/kg and for the crumb soy 1473 ± 15 Bq/kg.. he measured activities of the several analyzed foods were compatible with the values expected for non contaminated normal environmental samples, except for soy crumb, whose 40 K

    Full Text Available Abstract: This paper analyzes the spatial displacement of the productivity of Gross Value of Agricultural Production of the main activities and cultures of Parana’s State in 1970, 1996 and 2007. To this, we used a database of pre-existing on the Gross Value of Agricultural Production - the VBPA contained in the Agricultural Censuses (IBGE, Brazilian Institute of Geography and Statistics and the SEAB (Secretary of Agriculture and Supply of Paraná. The results showed that the VBPA of Paraná State has a spatial displacement during the period, where it was concentrated in 1970 in the northern portion of the state, influenced mainly by coffee plantations. In 2007, the most visible concentration hovered over the West and Southwest regions, and motion to expand the activities poultry and swine in those regions as well as crop production technicality as soybeans and corn. The findings of this study confirm the dynamism of the regions, as well as the impact of modernization on the field, and also highlights the role that agricultural activities have on the economy of the state of Parana.

    Full Text Available Sustainable use of soil, maintaining or improving its quality, is one of the goals of diversification in farmlands. From this point of view, bioindicators associated with C, N and P cycling can be used in assessments of land-use effects on soil quality. The aim of this study was to investigate chemical, microbiological and biochemical properties of soil associated with C, N and P under different land uses in a farm property with diversified activity in northern Parana, Brazil. Seven areas under different land uses were assessed: fragment of native Atlantic Forest; growing of peach-palm (Bactrys gasipaes; sugarcane ratoon (Saccharum officinarum recently harvested, under renewal; growing of coffee (Coffea arabica intercropped with tree species; recent reforestation (1 year with native tree species, previously under annual crops; annual crops under no-tillage, rye (Cecale cereale; secondary forest, regenerated after abandonment (for 20 years of an avocado (Persea americana orchard. The soil under coffee, recent reforestation and secondary forest showed higher concentrations of organic carbon, but microbial biomass and enzyme activities were higher in soils under native forest and secondary forest, which also showed the lowest metabolic coefficient, followed by the peach-palm area. The lowest content of water-dispersible clay was found in the soil under native forest, differing from soils under sugarcane and secondary forest. Soil cover and soil use affected total organic C contents and soil enzyme and microbial activities, such that more intensive agricultural uses had deeper impacts on the indicators assessed. Calculation of the mean soil quality index showed that the secondary forest was closest to the fragment of native forest, followed by the peach-palm area, coffee-growing area, annual crop area, the area of recent reforestation and the sugarcane ratoon area.

    Full Text Available Barbados cherry is a tropical fruit that when cultivated in subtropical areas is exposed to frosts which cause considerable damages to the leaves and can kill plants. The frosts of July 2000 in Northern Paraná State made possible the evaluation of 19 Barbados cherry genotypes propagated through cuttings. A minimum air temperature of –1,3°C was recorded on 17 July at the meteorological station; the minimum ground temperature was around –5,4°C. All plants were severely injured in 100% of leaves. The evaluation was made the following year to the frost, through sprouts status. It was observed that Barbados cherry genotypes present differences in cold hardiness. Some genotypes were killed and others survived, with good vegetation on the next year. The following genotypes presented the best recovery: ‘Cícero’, ‘Roseli’, ‘Carolina’ and ‘Lígia.’ The findings are discussed in relation to temperature limits reported in the literature.A aceroleira é uma planta de clima tropical que também tem sido cultivada em áreas subtropicais, ficando com isso sujeita à ocorrência de geadas, que causam danos consideráveis à folhagem e podem levar as plantas à morte. As geadas de julho de 2000 no Norte do Paraná possibilitaram a avaliação de 19 genótipos de acerola, propagados vegetativamente. A temperatura mínima foi de –1,3° C no abrigo meteorológico em 17 de julho, que corresponde a – 5,4 °C na relva. Todas as plantas tiveram danos em 100% das folhas. No ano seguinte à geada, avaliou-se a recuperação das plantas com base na brotação apresentada. Com os resultados obtidos, conclui-se que os genótipos de aceroleira apresentam respostas diferentes à geada, sendo que alguns são levados à morte e outros conseguem se recuperar na estação de crescimento seguinte. Os genótipos que apresentaram melhor recuperação foram: ‘Cícero’, ‘Roseli’, ‘Carolina’ e ‘Lígia’. Os resultados são discutidos em rela

  16. Molluskan fauna in two shell mounds in the State of Parana coast, Brazil

    Full Text Available The shell mounds are artificial formations consisting mostly of mollusk shells used in the feeding of the prehistoric peoples which inhabited our coast. These sites are found throughout the Brazilian coast, and hundreds of them were cataloged in the State of Paraná since the 1940s. The fragility of these sites, their importance as evidences of our prehistoric period, and its abrupt disappearance, justify the need for new researches which contribute to contextualize and draw up plans to preserve this heritage. The works related to the molluskan fauna found in the shell mounds are restricted to refer to the most common species and, sometimes, just their popular names. A greater knowledge on these prehistoric inhabitants’ diet allows a better understanding of ancient natural ecosystems. The survey of mollusks was carried out in the shell mounds Guaraguaçu and Boguaçu, in the towns of Pontal do Parana and Guaratuba, respectively, and performed through visual inspection, reading of specialized bibliography and comparison to previous works on the fauna of the shell mounds in the State of Parana coast. Altogether, 29 species were observed in the shell mound Guaraguaçu and 17 species were observed in the shell mound Boguaçu, resulting in a total of 31 species.

    Full Text Available The distance education (DE modality evolves as new Information and Communication Technologies (ICT are developed and based on the methodologies that are being used in the media dissemination of information, educational institutions and organizations take ownership of these innovations to promote their teaching processes. One of the methods that have achieved prominence is how e-learning, which is also called educational computer or online education, is conducted by the internet - synchronously or asynchronously, eliminating the figure of the pedagogical mediator in real time. This article aims to answer the main question: What is the perception of Parana civil servants, which undertake the distance e-learning methodology post-graduate programs in relation to the use of technologies and materials. The surveys of the study were 670 civil servants from Parana state, students of the post-graduation basis course in Public Management in e-learning methodology, which stems from Parana State Government's partnership with a federal institution of vocational and technological education. The research was conducted by using qualitative and quantitative approach, descriptive and questionnaire application method survey, containing 12 closed questions. The main results show that there is high familiarity and acceptance to e-learning. On the other hand, the use of teaching materials evidenced conservatism and attachment to printed learning materials, highlighting the printed book as a key to distance learning.

    2010-09-01

    Full Text Available The aim of this study was to evaluate the correlation between the constructs of quality of work life (QWL and lifestyle in Physical Education teachers from public schools in Parana State. The sample consisted of 654 teachers (299 men and 355 women, corresponding to a sampling error of 3.5%. A sociodemographic questionnaire, “Perceived Work Quality of Life Scale by Physical Education Teachers from Elementary to High School” and “Profile of Individual Lifestyle” were used for data collection. Statistical analysis was performed using the chi-square test and Spearman’s correlation test. The results showed the dissatisfaction of teachers with wages, working conditions and balance between work and leisure. Most subjects presented positive lifestyle behaviors, but the components nutrition, physical activity and stress management were a matter of concern. Internal evaluation of QWL yielded higher correlation coefficients than lifestyle. When comparing the two analytical matrices, low levels of correlation were observed between components and overall assessment of the constructs.

  2. Generation of Northern Parana High Ti/Y Basalts By Progressive Lithospheric Thinning Above a "Gough"-like Mantle Source.

    Peate, D. W.

    2015-12-01

    Stratigraphic and geochronologic data show that the high Ti/Y magma types (Pitanga & Paranapanema) of NW Paraná are the youngest magmatic phase in the Paraná-Etendeka flood basalt province and comprise ~50% of the total erupted volume. They are more homogeneous than low Ti/Y basalts in SE Paraná and the Etendeka, with a restricted range in Sr-Nd-Pb isotope composition (87Sr/86Sr 0.7055-0.7063; ɛNd -5 to -3; 206Pb/204Pb 17.7-18.2). Subtle differences between Pitanga and Paranapanema (Th/Ta, 206Pb/204Pb) are consistent with minor crustal assimilation. Pitanga show greater incompatible element enrichment compared to Paranapanema (Ti/Y 440-590 vs. 325-510; La/Yb 9.3-12.2 vs. 5.9-9.0), and have greater MREE/HREE enrichment (Dy/Yb 2.1-2.5 vs. 1.8-2.1). Boreholes and surface profiles reveal a consistent temporal transition from Pitanga to Paranapanema lavas, and the decrease in Dy/Yb requires a shallowing of the mean depth of melting, consistent with lithospheric thinning. Pitanga and Paranapanema lavas show Dupal characteristics (elevated Δ7/4Pb 8-13), distinct from Tristan hot-spot and S Atlantic MORB compositions, but similar to the EM-I endmember composition from Walvis Ridge DSDP Site 525A. Previous workers suggested a common origin for Parana high Ti/Y magmas and DSDP Site 525A in continental lithospheric mantle. However, recent comprehensive sampling of the Tristan - Gough - Walvis Ridge - Rio Grande Rise hotspot track has revealed spatial geochemical zonation with a northern "Tristan"-track and a southern "Gough"-track, and the "Tristan" component (Δ7/4Pb 3-6) is only found in samples < 70 Ma (Hoernle et al. 2015). The early hotspot track history is dominated by the "Gough" component (Δ7/4Pb 6-13), inferred to be derived from the African LLSVP, and this material has the compositional features (Sr-Nd-Pb-Hf isotopes, elevated La/Nb and Th/Nb) required for the mantle source for the Pitanga and Paranapanema magma types of the 135 Ma Paraná flood basalt

    Considering the growing interest of International Agencies and national Governmental organs in studies and measurements of radon activity in air, soil gas and ground water (mainly from artesian wells) as well as scarceness of such measurements at Brazilian territory, present studies were initiated by the Laboratory of Applied Nuclear Physics of Federal University of Technology - Parana (UTFPR) in collaboration with the Institute of Radiation Protection and Dosimetry (IRD) and the Center of Nuclear Technology Development (CDTN) of Brazilian Commission on Nuclear Energy (CNEN). This Collaboration started in 2003. Radon monitoring program is based mainly on use of Solid State Nuclear Track Detectors for radon activity measurements in air. Continuous electronic radon detectors are used for radon measurements in soil gas and water. Current work presents the results of indoor 222 Rn activity of dwellings and working places of Curitiba-PR and radon concentration in ground water samples from artesian wells from aquifers of the same area. The indoor measurements of radon activity were performed using Solid State Nuclear Track Detectors CR-39. After the exposition, CR-39 detectors were submitted to chemical development which permitted to make alpha particle tracks counting. The results of calibration of CR-39 together with efficiency of used exhalation chambers as well as alpha particle tracks chemical development procedure were performed in cooperation with CDTN and collaboration with the National Institute of Radiological Sciences (NIRS). The major part of indoor 222 Rn concentration in residences was found below 100 Bq/m3. In the case of working places, all measurements present 222 Rn concentration bellow 100 Bq/m3. The studies of radon activity in water were performed using the samples of water from artesian wells submitted to recursive measurements by instant radon detector AlphaGUARD PQ2000 PRO during few weeks with intervals of about 4 days between each measurement

    Full Text Available Cotton is cultivated in the North and West of Parana State, southern Brazil, under conditions of climatic risk variable in space and time. Risks of temperature below 15ºC at the establishment period, daily average temperature below 20ºC at the stage of cotton boll opening, and soil water deficit for both plant establishment and flowering periods, were estimated to identify homogeneous zones with sowing periods of lower climatic risk. The time interval with adequate temperature, associated with minimum risks of the other factors and yield data from field experiments allowed the identification of seven distinct zones, with best sowing periods ranging from September 20 to November 20. Official credit to the farmers is conditioned by the Central Bank of Brazil upon following these recommendation of best sowing periods for each municipality.O algodoeiro é cultivado nas regiões norte e oeste do Estado do Paraná, sob condições climáticas de risco variáveis no tempo e espaço. Os riscos de temperatura média do ar abaixo de 15ºC na fase de estabelecimento da cultura, temperatura média diária abaixo de 20ºC para completar a abertura das maçãs e déficit de água no solo nas fases de estabelecimento e florescimento, foram estimados para identificar, com o suporte de dados de área plantada e dados de produtividade, as zonas homogêneas com períodos de semeadura de menor risco. Os intervalos de tempo com temperatura adequada, associados com mínimo risco de deficiência hídrica e dados de produtividade, permitiram a identificação de sete zonas distintas, com melhores períodos de semeadura entre 20 de setembro e 20 de novembro. As recomendações de melhores períodos de semeadura para cada município devem ser seguidas pelos agricultores que solicitam crédito bancário oficial para o plantio de algodão.

    Goncalves, N.M.M.

    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

    Full Text Available The study aimed to fit mathematical models for the construction of Site Index curves and to estimate heights at different ages for Eucalyptus grandis in the Campos Gerais region, Parana State. The data used to fit the models came from permanent, temporary plots and pre-harvesting inventory, covering ages from 2.5 to 26.5 years. Several models were tested to represent the sites and the hypsometric relationship. The Site Index curves were constructed by the guide-curve method. For the Site Index, the Chapman-Richards model showed the best fit and precision statistics, generating 5 Site Index curves (range of 5 m with the Chapman-Richards model. The four hypsometric models tested showed satisfactory performance and similar statistics and the inclusion of the variables dominant height or site index did not substantially improve the goodness of fit statistics, but the residues were more homogeneous and closer to zero.

    Considering that radon and its progeny exposure is proved to be the main cause of lung cancer among nonsmokers and occupation-time at some commercial establishments and workplaces is equal or even bigger then at domiciles and dwelling, present study has been spread to the constructed closed environment and workplaces of commerce and productive sector. The measurements were performed by the Laboratory of Applied Nuclear Physics of UTFPR in 2009 - 2011 when 120 detectors were installed at domiciles and workplaces of Curitiba, Parana St., Brazil. Experimental setup was based at CR-39 detectors that were installed in diffusion chambers protected with filters. In collaboration with CDTN/CNEN it was performed the calibration of CR-39 detectors at the NIRS in Japan. The exposure time was set to be of 100 days. Alpha particle track development was performed using 6.25M sodium hydroxide (NaOH) solution and ethanol (2%) during 14 hours at 70 deg C. The counting was conducted using an optical microscope. Measured 222 Rn activity levels in dwellings varied between 4.37 Bq/m 3 and 320.82 Bq/m 3 resulting at an average of 46.94 Bq/m 3 . Indoor measurements at workplaces presented the variation of radon activity concentration between 3.08 Bq/m 3 and 67.50 Bq/m 3 resulting at the average of 34.51 Bq/m 3 . Considering the recommendations of the World Health Organization, UNSCEAR and the International Commission on Radiological Protection (ICRP) concerning the radon-in-air concentration inside the dwellings that can reach 200 Bq/m 3 taking into account the occupation-time of 7000 hours/year, obtained results are within normal limits and no mitigation measures have to be performed.

    Canine babesiosis is a worldwide disease caused by the protozoan of Babesia genus. Babesia canis and B. gibsoni are both species that naturally infect dogs. The objective of this study was to evaluate the infection of Babesia species in dogs attended at the Londrina State University Veterinary Teaching Hospital (HV-UEL). It was selected 282 dogs seen at the Londrina State University Veterinary Teaching Hospital (HV-UEL) between April of 2005 and May of 2006. They presented anemia (Packed Cell Volume<25%), thrombocytopenia (Platelet count <150000/mm3), leukopenia (White blood cell count<5000/mm3) or a combination of two or three of these alterations at the moment of the consultation. The presence of Babesia sp was determined by the amplification of a specific fragment of DNA of the Babesia genus by PCR. Microscopic examination of Giemsa-stained blood smears detected 38 (13.5%) positive samples against 105 identified by PCR from 282 dogs. The positive samples were submitted to PCR-RFLP by Hinf I that allows distinguishing the species of B. canis vogeli and B. gibsoni. From 282 dogs, Babesia sp infection was identified in 105 (37.2%). From these 105 positive samples, the PCR-RFLP identified 66 (23.4%) samples with a profile compatible to B. canis vogeli and 39 (13, 8%) to B. gibsoni. As conclusions, the results obtained allow to affirm that the babesiose is an important differential for dogs that present anemia, leukopenia and thrombocytopenia and, B. canis vogeli is the subspecies that is present in the most of the cases of babesiose in the population of dogs studied and, that B. gibsoni is also present causing babesiosis in dogs of the Londrina region, Parana State, Brazil.

    Rural Electrification Cooperatives (REC) has already played a fundamental role in rural electrification process. Bearing in mind changes in legislation towards specific laws that tend to facilitate energy distribution and trade relations, REC has increased there potential to contribute even more to above mentioned process. The present work intended to assess how REC settled in Parana State have adapted themselves to the privatised electrical business scenario as well as to new legal requirements and the presence of great national and international corporations disputing the energy market. Such new electrical market model favors huge changes to the electrification cooperatives, with the possibility of transforming cooperatives into public service energy with governmental permission. Moreover, it also represents a giant challenge for their insertion and continuity in such new scenario, in as much as the REC classification process as public service companies for electric energy distribution has been carried out for years, added to the scarcity of investments on state cooperatives, therefore restricting electric energy supply to residential, rural and irrigation sectors.

    During the period of nuclear tests between 1950 and 1960, an input of artificial 14 C (fallout effect) occurred in the natural reservoirs. 14 C determinations in the Northern Hemisphere showed values of Δ 14 C up to 960 in the year of 1964. To determine the fallout 14 C activity in Brazil, wood samples from Araucaria angustifolia (Bert.) O. Kuntze, Araucariaceae, were collected in Arapoti-PR (24 deg 11 S , 49 deg 58 O ). The annual tree rings were selected by dendrochronology. The cellulose was extracted and its 14 C activity determined by liquid scintillation method. The results showed a significant increase of the Δ 14 C up to 590 in 1965, about 60% higher than the natural activity, gradually decreasing after the end of nuclear tests. These results were correlated with those obtained in the Northen Hemisphere and will be used in the studies of CO 2 mechanisms distribuition to the atmosphere and other natural reservoirs. (author)

    Aphid parasitoids are common in Brazilian wheat fields, and parasitize aphids at the wheat tillering stage. However, there is little information available about when this natural enemy occurs in wheat crops. This study investigated the initial occurrence of aphid parasitoids in four commercial wheat crops in northern Paraná during the 2009 crop season. We installed two Malaise traps at each wheat farm, and 400 tillers were assessed weekly in each field for aphid abundance. During this study, we captured 4,355 aphid parasitoids and 197 aphids. Three species of braconid parasitoids were identified, including Aphidius colemani (Viereck 1912), Lysiphlebus testaceipes (Cresson 1880), and Diaeretiella rapae (McIntosh 1855). The aphids species identified were Rhopalosiphum padi (Linnaeus 1758) and Sitobion avenae (Fabricius 1775). This study showed that aphid parasitoids are present in wheat crops even when aphid densities are low, and in one farm, occurred before the aphids colonization. These reports can justified the high efficiency of these natural enemies against aphids in wheat fields. © The Author 2015.

  20. Geochemical characterization of Parana Basin volcanic rocks: petrogenetic implications

    1988-01-01

    A detailed study of the geochemical characteristics of Parana Basin volcanic rocks is presented. The results are based on the analyses of major and trace elements of 158 samples. Ninety three of these volcanic samples belong to 8 flow sequences from Rio Grande do Sul and Santa Catarina States. The remaining sixty five samples are distributed over the entire basin. In order to study the influence of crustal contamination processes in changing chemical characteristics of the volcanic rocks, 47 samples representative of the crystalline basement of the southern and southeastern Parana Basin were also analysed. Several petrogenetic models were tested to explain the compocional variability of the volcanic rocks, in particular those of southern region. The results obtained sugest an assimilation-fractional crystallization process as viable to explain the differences of both the chemical characteristics and Sr isotope initial ratios observed in basic and intermediate rocks. A model involving melting processes of basic material, trapped at the base of the crust, with composition similar to low and high TiO 2 basalts appears to be a possibility to originate the Palmas and Chapeco acid melts, respectively. The study of ''uncontaminated'' or poorly contaminated low TiO 2 basic rocks from the southern, central and northern regions shows the existence of significant differences in the geochemical charactetistics according to their geographical occurrence. A similar geochemical diversity is also observed in high TiO 2 basalts and Chapeco volcanics. Differences in incompatible element ratios between low and high TiO 2 ''uncontaminated'' or poorly contaminated basalts suggest that they could have been produced by different degrees of melting in a garnet peridotite source. Geochemical and isotopic (Sr and Nd) data also support the view that basalts from northern and southern regions of Parana Basin originated from mantle source with different composition. (author) [pt

    Full Text Available The composition and biomass of the microalgal community at the water-column/sediment interface on the continental shelf off Parana State (Brazil were studied every 2 months during 1999. Samples for cell identification and determination of chlorophyll a were taken from the interface layer and at discrete depths up to 4 m above the sediment. Results showed a community mainly formed by benthic and planktonic diatoms >30 µm, benthic diatoms 30 µm, which accounted for most of the pigment biomass, were resuspended from the interface after turbulent periods, and may take advantage of calm periods to stay and grow at the interface. Small benthic diatoms were more susceptible to wind-induced turbulence occurring in higher densities in the water column just above the water-sediment interface. A cyanobacterial bloom (Trichodesmiun was observed at these bottom layers in the spring-summer periods.A composição geral e a biomassa da comunidade microalgal da interface sedimento/água da plataforma do Estado do Paraná (Brasil foram estudadas em 1999 em relação ao regime de ventos. A cada dois meses foram coletadas amostras para a identificação de organismos e determinação de clorofila a, na interface água-sedimento e em profundidades discretas, ao longo da coluna d'água, até 4m acima do sedimento. Os resultados obtidos revelaram uma comunidade constituída principalmente por diatomáceas planctônicas e bentônicas maiores que 30 µm, diatomáceas bentônicas menores que 30 µm, e cianobactérias coloniais. As densidades celulares foram geralmente mais altas na interface. Eventos de mistura e sedimentação parecem ser determinantes na regulação da composição e biomassa de tais comunidades. Formas menores, mais susceptíveis à turbulência, dominaram a comunidade de água de fundo na maioria das ocasiões, e foram as mais abundantes na interface apenas em períodos de extrema estabilidade.

    This study reports the fauna and frequency of sandflies in domestic animal shelters, residences and other ecotopes in rural areas of the municipality of Bandeirantes, Paraná State. Sandflies were collected twice in eight rural villages by using Falcon traps from 8pm to 6am in 2008. In these localities 4,790 sandflies were collected, which were represented by ten sandfly species, prevailing of Nyssomyia neivai and Nyssomyia whitmani species. It was observed that animal shelters are the domestic ecotopes where there is the greatest frequency of these insects. The localities where the collections were made had the environmental characteristics that allow the persistence of transmission of parasites from the American tegumentary leishmaniasis. Although the fauna and the behavior of sandflies species are similar in different localities, the method of controlling these insects should be adjusted to the environmental characteristics of each one of the most diverse endemic areas of American tegumentary leishmaniasis in the municipalities of Paraná State.

    Gamma-ray spectrometry, electrical resistivity, and magnetic susceptibility measurements were taken from agricultural areas near the City of Maringa, in the Northwest region of the Parana state, south Brazil, in order to characterize the spatial distribution of radionuclides (K, eU, and eTh), the apparent resistivity, and the magnetic susceptibility determined for soils. Three different types of soils are present in this agricultural area: Alfisoil, clayey texture Oxisoil, both deriving from Lower Cretaceous basalts of the Serra Geral Formation; and medium texture Oxisoil from reworked Serra Geral and Goio-Ere formations, the latter deriving from sandstones of the Upper Cretaceous Caiua Group. It could be observed that in more clayey soils both concentration of radionuclides and susceptibility values are higher than in more sandy soils, especially due to the higher adsorption in the former and to the higher availability of magnetic minerals in the latter. The average ppm and Bq Kg{sup -1} grades for K, eU, and eTh in the areas under anthropic activity are of 1766-54.75, 0.83-10.22, and 1.78-7.27, respectively. These grades are significantly higher than those of non-occupied or non-fertilized areas (1101-34.15 K, 0.14-1.69 eU, and 1.31-5.36 eTh in ppm and Bq Kg-1, respectively.) Correlations were observed between uranium and clay, uranium and magnetic susceptibility, uranium and organic matter, and between electric resistivity and clay grades. Varied concentrations of radionuclides were also observed in different fertilizer formulations applied to soy and wheat cultures. Apparent electric resistivity values between 25 and 647 Ohm.m and magnetic susceptibility values between 0.28 e 1.10 x 10-3 SI due to clay and magnetic minerals represented important soil discrimination factors in the study area that can be incorporated as easy, low-cost soil mapping tools.

    2013-01-01

    Primordial, or terrestrial natural radionuclides, are found in different amounts in the environment. In dwellings, an important dose increment is due to building materials, which contribute for both the external gamma dose from the radionuclides of the 238 U, 235 U and 232 Th series and the natural 40 K and the internal dose, due mainly to 222 Rn inhalation. Once granitic rocks are widely used both as construction materials or structural flooring, those rocks can become an important dose source, depending on the content of concentrations of radioactivity, and the construction application. In this work, a database for granitic rocks of the crystalline shield of Parana (mainly in the Metropolitan Region of Curitiba, RMC), used in civil construction, was generated, evaluating in terms of radiological protection the external and internal dose increments, caused by the use of these materials. Also, possible correlations between the 226 Ra activity concentration, the 222 Rn exhalation rate, density, porosity and chemical composition (oxide content) in these samples had been studied. The external dose was assessed by gamma-ray spectrometry with High-Purity Germanium detectors, where the activity concentration of the radionuclides 232 Th, 226 Ra and 40 K are the parameters used in dosimetric models (Dosimetric Indexes), which established limits in accordance with the form, amount and application of material of construction. For the calculation of the annual effective external dose it was assumed a room model with dimensions of 4 m x 5 m x 2:8 m and all walls internally covered with 2 cm thickness of granite and an annual exposure time of 7000 h as suggested by the European Commission of Radiological Protection for internal superficial coating materials. The internal exposure was assessed from the radon concentration in the air of the room model, simulated from the superficial exhalation rate of 222 Rn. The exhalation rate was determined by the passive detection technique

The majority of the insects (ca. 90%) with mature reproductive organs was observed during the summer (December-March), when E. heros was found on soybean or on sunflower; in the beginning of autumn, most insects (87%) showed immature reproductive organs, and they were found on star bristle and under fallen leaves. Bugs with mature reproductive organs had more developed shoulders (3.23 and 3.27 mm, for males and females, respectively) than bugs with immature organs (2.91 and 2.89 mm, for males and females, respectively). Two distinct body colors, dark brown and reddish brown, were observed. Nevertheless, the reddish brown was the predominant color of both mature and immature adults during all year. Adults were parasitized by Hexacladia smithii (Ashmead) (Hymenoptera: Encyrtidae) and Tachinidae mainly Trichopoda giacomellii (Blanchard) (Diptera: Tachinidae) (80% and 40% of parasitism in male and female, respectively) during summer (December), when the bugs colonized sunflower. In soybean, 12% of males and 10% of females were parasitized, whereas in fallen leaves, the parasitism rate was 5% in both sexes.These results showed that in autumn/winter (shorter photoperiod) the majority of the insects were inactive under fallen leaves, showing immature reproductive organs and less developed shoulders, indicating that, at this time, these bugs were in diapause.

    Primordial, or terrestrial natural radionuclides, are found in different amounts in the environment. In dwellings, an important dose increment is due to building materials, which contribute for both the external gamma dose from the radionuclides of the {sup 238}U, {sup 235}U and {sup 232}Th series and the natural {sup 40}K and the internal dose, due mainly to {sup 222}Rn inhalation. Once granitic rocks are widely used both as construction materials or structural flooring, those rocks can become an important dose source, depending on the content of concentrations of radioactivity, and the construction application. In this work, a database for granitic rocks of the crystalline shield of Parana (mainly in the Metropolitan Region of Curitiba, RMC), used in civil construction, was generated, evaluating in terms of radiological protection the external and internal dose increments, caused by the use of these materials. Also, possible correlations between the {sup 226}Ra activity concentration, the {sup 222}Rn exhalation rate, density, porosity and chemical composition (oxide content) in these samples had been studied. The external dose was assessed by gamma-ray spectrometry with High-Purity Germanium detectors, where the activity concentration of the radionuclides {sup 232}Th, {sup 226}Ra and {sup 40}K are the parameters used in dosimetric models (Dosimetric Indexes), which established limits in accordance with the form, amount and application of material of construction. For the calculation of the annual effective external dose it was assumed a room model with dimensions of 4 m x 5 m x 2:8 m and all walls internally covered with 2 cm thickness of granite and an annual exposure time of 7000 h as suggested by the European Commission of Radiological Protection for internal superficial coating materials. The internal exposure was assessed from the radon concentration in the air of the room model, simulated from the superficial exhalation rate of {sup 222}Rn. The exhalation

    Full Text Available The aim of this study was to evaluate the correlation between the constructs of quality of work life (QWL and lifestyle in Physical Education teachers from public schools in Parana State. The sample consisted of 654 teachers (299 men and 355 women, corresponding to a sampling error of 3.5%. A sociodemographic questionnaire, “Perceived Work Quality of Life Scale by Physical Education Teachers from Elementary to High School” and “Profile of Individual Lifestyle” were used for data collection. Statistical analysis was performed using the chi-square test and Spearman’s correlation test. The results showed the dissatisfaction of teachers with wages, working conditions and balance between work and leisure. Most subjects presented positive lifestyle behaviors, but the components nutrition, physical activity and stress management were a matter of concern. Internal evaluation of QWL yielded higher correlation coefficients than lifestyle. When comparing the two analytical matrices, low levels of correlation were observed between components and overall assessment of the constructs.

    In high resolution gamma-ray spectrometry correct determination of {sup 226}Ra, {sup 232}Th and {sup 40}K activities concentrations involve, beside accurate areas determinations, the use of precise efficiency calibration curves. As the efficiency calibration curve used for activities calculations was obtained with an aqueous standard multiradionuclides solution and the geological samples have apparent densities higher than the efficiency standard one, a correction of the efficiency curve is necessary. In this work, the self-attenuation correction factors were measured for sixteen geological samples from the Parana State Brazil crystalline shield, including lithotypes like rhyolite, granite, sienite and basalt, with apparent densities varying from 1.42 g cm-3 to 2.02 g cm-3.

    A lead and strontium isotope study was carried out on galena, barite and calcite from Pb-Ag syngenetic stratiform (Perau type) and hydrothermal veins (Panela type) deposits from Vale do Ribeira region (Sao Paulo and Parana states). The leads from the Perau and Panelas type deposits have respectively isotope ratios (sup(206)Pb/ sup(204)Pb 16.157 to 16.505 amd 16.520 to 17.273; sup(207)Pb/ sup(204)Pb = 15.466 to 15.720 and 15.470 to 15.780 and sup(208)Pb/ sup(204)Pb = 36.370 to 36.763 and 37.043 to 38.243), that defined a Stacey and Kramers model ages mainly concentrate within 1.7-1.5Ga. A review of published Pb isotopic compositions for these deposits and considerations of new Sr isotope data and Pb results using plumbotectonics model, indicate that the Perau type mineralizations are related to the syngenetic process and the Pb are derived from upper crust with a short crustal residence time. For the Panelas type deposits the Pb and Sr isotope studies support the conclusion that the ores were emplaced during regional metamorphism and the Pb were derived from lithologically complex source which may include metasedimentary and basement rocks.

    Full Text Available The present study aimed to identify Eimeria species in young and adult sheep raised under intensive and / or semi-intensive systems of a herd from Umuarama city, Parana State, Brazil using the traditional diagnostic methods and to correlate the infection level/types of infection in the different age/system in this herd. Fecal samples were collected from the rectum of 210 sheep and were subjected to laboratory analysis to differentiate the species. Furthermore, animals were observed to determine the occurrences of the clinical or subclinical forms of eimeriosis. Out of the 210 collected fecal samples, 147 (70% were positive for Eimeria oocysts, and 101 (47.86% belonged to young animals that were raised under intensive and / or semi-intensive farming systems. Oocysts from 9 species of Eimeria parasites were identified in the sheep at the following prevalence rates: E. crandallis, 50.0%; E. parva, 21.6%; E. faurei, 8.1%; E. ahsata, 8.1%; E. intricata, 5.4%; E. granulosa , 2.7%; E. ovinoidalis , 2.0%; E. ovina , 1.3%; and E. bakuensis , 0.6%. There were no differences regarding the more frequent Eimeria species among the different ages of animals or between the different farming management systems. Based on these data, E. crandallis was the most prevalent, followed by E. parva and E. faurei species, regardless of the age. Higher parasitism was diagnosed in the young animals that were raised in a confinement regime, and the disease found in the herd was classified as subclinical. Further studies should be conducted in this herd, to verify if the eimeriosis subclinical can cause damage especially in young animals with a high level of infection.

    Systematic collections of anophelines were conducted from November 1995 to August 1995 from 18:00 to 20:00 hr using Shannon traps and human-bait along the lake margin which forms the Itaipu Hydroelectric Reservoir, State of Parana, Brazil. Species prevalence was studied at 15 min intervals. Anopheles albitarsis sensu latu and An. galvaoi, were the most frequently collected mosquitoes. All Anopheles species populations peaked between 18:45 and 19:30 hr. The observations illustrate the existence of haematophagic activity cycle during the early evening hours: exogenous stimulus (the beginning of sunset) Shannon trap (light attraction) human bait (haematophagy) rest and digestion exogenous stimulus Shannon trap or surrounding vegetation. The greater abundance of An. albitarsis collected in human-bait and Shannon trap suggests it may be a potential malaria vector in the region. (author) 20 refs.

  2. Structural, petrological and geochronological analysis of the lithotypes from the Pien region (Parana State, Brazil) and adjacences

    Harara, Ossama Mohamed

    1996-01-01

    The Pien area presents the major geotectonic domains separated by the Pien Shear Zone (PSZ). The northern one is the Rio Pien Granite-Mylonitic Suite composed by calc-alkaline granitoids of Neoproterozoic age. The southern domain is represented by the Amphibolite-Granulite where high grade metamorphism took place at the end of paleoproterozoic time. Considering the identified lithotypes, their geochemical affinity (particularly the Ti, Cr, Ni and REE content) and the geological context observed in the area, a geotectonical model of active continental margin related to subduction SSZ (Supra-Subduction Zone) is proposed. K-Ar on plagioclase from gabbronorites gave Neoproterozoic ages although Sm-Nd whole rock isochron yielded Paleoproterozoic ages. Based in geochemical data, it is proposed that the biotite gneiss and biotite-amphibole-gneiss which occur near the PSZ have a shoshonitic to high-K calc-alkaline features which are characteristic of active continental margins. K-Ar on biotite extracted from these rocks, gave Neoproterozoic ages. The available radiometric data for the Rio Pien mylonitic granitoids show that between 650-595 Ma the generation, deformation and cooling below the isotherm of 250 deg C occurred. On the other hand, the geochronological data for the Agudos do Sul Massif are in the 590-570 Ma interval showing its younger generation. The Sr 87 / Sr 86 initial ratios for both granitoids suggest more involvement of the continental crust in the origins of Agudos do Sul granitic Massif. The analyses of the entire set of the available data for the Pien area allows the suggestion of a geotectonic scenery related to the evolution of an active continental margin during the collages associated to the Brasiliano Cycle

    The calcite deposits and the calcitic marbles hosts occur in Serra do Carumbe, in the Vale do Ribeira region, Parana State, were studied in their geochemical and isotopic aspects viewing the gathering of information about their genesis and economical use. The calcite deposits are constituted by veins and lenses, being three of them concordant and one discordant in relation to the S 0 from the hosting marbles. In these deposits four main types of calcite were recognized: rombohedrical, fibrous, banded and microcrystalline. The calcite reveal themselves having high purity, with CaO concentration above 55.30% and MgO below 0.42%. The lithogeochemical study of the marbles sequence was conducted in various suites revealing an uniformity in their composition, with high values of CaO (above 46.92%) in relation to the MgO values (below 3,37%), what favors their use for cement manufacture, except in sectors that suffered fault influences, where the marbles are impure (siliceous, magnesian, ferruginous and aluminous). Regarding their trace elements content, the hosting calcitic marbles have higher concentrations than the calcite, in the elements Sr, B, Ba and Mg, what makes evident their different formation environments. The δ 13 C values from calcite range from –9,02 to –12,24 ‰ , referring to PDB, while the values δ 18 O range from 24,48 to 25,23 ‰, referring to SMOW; meanwhile, for the calcitic marbles, the δ 13 C values range from –4,03 to 1,42‰ and of δ 18 O range from 20,71 to 23,00 ‰. The high δ 18 O values would indicate enrichment referring to the interaction of the calcite's generator fluid with the carbonatic host rock. The δ 13 C values indicate origin from hydrothermal solution for the calcite, although they would not allow to conclude if their sources would be superficial or profound. As for the hosting calcitic marbles, the isotopic values indicate genesis from pre-cambrian marine limestone. (author)

    Surface samples and cores from 31 exploratory wells were chosen as being the most representative among those drilled by PETROBRAS across the Parana Sedimentary Basin, from Mato Grosso and Goias to Rio Grande do Sul. Their analysis yielded a large amount or Saccites, Monoletes and Monocolpates spores, in addition to representatives of Tasmanales. From the great number of identified forms, 40 species - characterized by their wide geographical distribution allied to a short vertical range - were selected and used as a basis for the biostratigraphical subdivision of the Gondwana section of this sedimentary basin. This biostratigraphic column was divided into six main intervals, designated by the letters G to L, some with further subdivisions. The comparison of the species with those described from other regions provided sufficient geochronological data for the dating of the different intervals. It also demonstrated that the Upper Paleozoic sedimentary sequence in the Parana Basin ranges from the Upper Pennsylvanian (Stephanian C) to the Upper Permian (Kazanian). To complete the paleogeologic data the previously established zonation of the Devonian section was also included. The correlation of the biostratigraphic intervals across the basin and their relationship with the rock-stratigraphic units are demonstrated in several sections. The interpretation of these sections and of the biostratigraphic interval isopachous maps provided important information on the paleogeographic development of the basin. Among the more significant results is evidence of the start of the Permo-Carboniferous sedimentation in the northern regional depression, of a subsequent southward tilting of the basin accompanied by the progressive advance of the deposits toward the Rio Grande do Sul shield and of a Lower Permian lacuna in eastern Parana indicating the beginning of the epeirogenic process which culminated with the rise of the Ponta Grossa arch.

METHODS: The population studied was composed of the Japanese migrants - Issei - living in the State of Parana, Brazil, of more than 50 years of age, identified in the X General Brazilian Census of 1st September, 1991. Information on deaths which occurred between 1st March 1990 and 28th February, 1993, was obtained through the Ministry of Health data base. The main causes of death were analysed after the calculation of the age-adjusted death rates, using the world standard population older than 50 years old, for each sex, for the Issei, the inhabitants in Japan and in Paraná. Standardized Risk Ratio - SRR - and respective 95% confidence interval were estimated for selected causes among Issei versus the population living in Japan and Issei versus persons living in Paraná. RESULTS: Among the main results, it was observed that the female Issei mortality rate was in an

    Full Text Available Canine monocytic ehrlichiosis caused primarily by Ehrlichia canis and canine thrombocytic anaplasmosis induced by Anaplasma platys are important emerging zoonotic tick-borne diseases of dogs. There is evidence that these pathogens can also affect humans. This study evaluated the presence of E. canis and A. platys in blood samples collected from 256 domiciled dogs in the municipality of Jataizinho, located in north region of the State of Parana, Brazil, by PCR assay. The occurrence of E. canis and A. platys was 16.4% (42/256 and 19.4% (49/256, respectively; while 5.47% (14/256 of the dogs evaluated were co-infected by these two organisms. The presence of E. canis and A. platys was not significantly associated with the variables evaluated (sex, age, outdoor access, and presence of ticks during blood collection. Infection of dogs by E. canis was associated with anemia and thrombocytopenia, while infection induced by A. platys was related only to thrombocytopenia. Canine monocytic ehrlichiosis and canine thrombocytic anaplasmosis should be included in the differential diagnoses when these hematological alterations are observed during routine laboratory evaluation of dogs.Erliquiose monocítica canina, causada principalmente por Ehrlichia canis, e anaplasmose trombocítica canina, devida a infecção com Anaplasma platys, são importantes doenças transmitidas por carrapatos que acometem os cães, com evidências que podem também acometer o homem. O presente estudo avaliou a ocorrência desses agentes em amostras de sangue de 256 cães domiciliados na cidade de Jataizinho, na região Norte do Paraná, Brasil, utilizando a técnica da Reação em Cadeia da Polimerase (PCR.

    This work has as its main objective the geomechanical characterization on the future rocky mass foundation of the Tijuco Alto dam, sited at the Ribeira river, in the cities of Ribeirao, Sao Paulo state and Adrianopolis, Parana state, Brazil, owned by the Companhia Brasileira de Aluminio (Brazilian company of Aluminium). 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)

    Possession states are still commonly seen in developing societies as acceptable cultural phenomena in normal persons as well as in those with psychiatric illness. 'Possession' is defined here as the experience of being taken over, controlled or occupied by another spirit or force. This is a descriptive cross-sectional study of possession states among psychiatric patients, general population and popular adepts in Northern Sri Lanka, using semi-structured questionnaires and clinical observations. Thirty psychiatric patients were identified as having possession states. They were compared with 30 controls each from the general population admitted to a general hospital outpatient department and selected popular adepts in the community. The latter are individuals who are well known as having possession states. An analysis of social factors and other variables showed that education, marital status, age, employment, strength of belief, alterations in personality, past or family psychiatric history, previous exposure to similar phenomena, help-seeking behavior and treatment outcome differed between the three groups. Religion of the subjects or recent changes in values showed no correlation with possession while monetary gain from possession states showed only a partial correlation. Western medical treatment was of value only when possession states were seen as part of psychotic illness. Possession is a spectrum of experiential and behavioral phenomena seen in culturally acceptable form in normal people, popular adepts, as well as manifestations of psychotic illness. Possession states which fit normal cultural stereotypes could, if necessary, be better managed by traditional methods. However, clinicians need to be familiar with culturally abnormal forms of possession which are manifestations of psychotic illness that benefit from western psychiatric treatment. (c) 2008 S.

    This study was performed with PA thorax examinations of adult patients performed with CR equipment in a clinic of Pato Branco, Parana state, Brazil. The values of K{sub a,E} were estimated from irradiation parameters and the yield of X ray tube. The absorbed doses in organs and tissues of patients, and the effective risks of cancer incidence were estimated by using the CALDose{sub X}-3.5 computer program. The image quality was evaluated base on criteria established by European Community. The third quartile of the K{sub a,}E estimated was 0.170 mGy, lower than the reference level established by the Brazilian Ministry of Health. The organs that presented the largest absorbed doses were: lungs (36+-16 micron Gy), kidneys (25+-14 micron Gy) and spleens (23.2+- micron Gy). The incidence of of cancer was of 0.098+-0.051 for case of 100,000 exposed persons. All the image evaluated obtained conformity over 85% of the european quality criteria

    The measurement of {sup 137} Cs redistribution in the field allows the determination of soil erosion/accumulation. The {sup 137} Cs activity of soil samples, taken from a small basin at the North of Parana, were measured employing a HPGe gamma ray detector and a standard spectrometric nuclear electronic chain. Standard oil samples with known concentrations of {sup 137} Cs were prepared for the detection efficiency determination. Soil loss or gain was measured at the top, midslope and low slope regions, for six different transects at the investigated small basin. (author) 47 refs., 31 figs., 11 tabs.

    Full Text Available Aphids (Hemiptera: Aphididae are the main pest of wheat (Hemiptera: Aphididae in several countries. In Brazil, the Biological Control of Wheat Aphids released millions of aphid parasitoids (Hymenoptera: Braconidae and Aphelinidae on wheat fields and in the present moment the chemical control is rarely necessary. However, since the 80’s few studies was carried out to evaluate the species established in Brazil. For this reason, the aim of this study was to record the species of aphid parasitoids that occur in wheat in the northern region of Parana state, Brazil. Four commercial wheat fields were investigated in the agricultural years of 2008 and 2009. The aphid parasitoids were captured with traps (Moericke and Malaise and aphid mummified were collected. In total, six species of parasitoids were found, Aphidius colemani, A. uzbekistanicus, A. ervi, Aphidius rhopalosiphi, Diaeretiella rapae e Lysiphlebus testaceipes. These results contribute with the register of three exotic species in Parana, and confirm the establishment of A. rhopalosiphi in the country. We emphasize the need for further studies in other regions of the country, as other species introduced also need to have their establishment confirmed.Os pulgões (Hemiptera: Aphididae são pragas de extrema importância em cereais de inverno no mundo todo. No Brasil, o programa Controle Biológico de Pulgões do Trigo liberou milhões de parasitoides (Hymenoptera: Braconidae e Aphelinidae nas áreas tritícolas, reduzindo expressivamente a população da praga, e atualmente raramente o controle químico se faz necessário. Entretanto, desde a década de 80 poucos trabalhos de campo tem sido realizados para verificar as espécies efetivamente estabelecidas no País. Por esta razão, este estudo objetivou registrar as espécies de parasitoides de pulgões ocorrentes em lavouras de trigo na região Norte no Paraná. O trabalho foi realizado em quatro áreas comerciais de trigo, durante as safras

    With more than 200 species worldwide, Hydrellia Robineau-Desvoidy is the largest genus of the family Ephydridae (Diptera). However, knowledge of this genus is much reduced in Brazil and throughout the Neotropical Region, where only 8 species are known, including one from Brazil (H. xanthocera Cresson). The objective of this study is to review the species of Hydrellia from Brazil, with an emphasis on the faunas of Paraná and Rio de Janeiro states. Six new species are described: H. bocaiuvensis sp. nov. (Brazil, Paraná, Bocaiúva do Sul, 25°14.9'S, 49°8.9'W, 890 m), H. longiseta sp. nov.

    1998-01-01

    As a result of Brazil's centralized administration in the past, various parts of the public service were somewhat inefficient. Another reason was the size of the country. To improve the situation in the health sector, it was decided to transfer administrative responsibility to the municipal authorities. Accordingly, the public health system is now defined under the appropriate legislation as the 'Unified Health System' (SUS), comprising federal, state and municipal levels. This system promotes decentralization of therapeutic or preventive services (including the Radiation Facility Health Inspectorate) and proposes any additional legislation required. In Parana the Radiation Facility Health Inspectorate has 3600 organizations listed, employing ionizing radiation in medicine, industry and research, which need to be regularly inspected for licensing and control. In 1994, 50% of the annual inspection target in the state was attained. The Radiation Safety Programme for the Health Departments in Parana directs these activities in this State. Its strategies are: (1) to establish implementation phases for activities planned for each area; (2) to take advantage of the SUS structure to introduce or expand operational services at the primary, secondary and tertiary levels with appropriate equipment. The tertiary level involves co-ordination of the Programme and complementary executive functions, as well as maintaining an information system with other related organizations. The other levels include licensing, control and emergency response. As the Programme develops, indicators will be established to help identify progress achieved and correct operating strategy where necessary. Thus, the services provided to the public will be enhanced in quality and the radiation doses reduced. In addition, in emergency situations, the time elapsing between the event and its notification to the authorities will be reduced, minimizing the consequences of any accidents. (author)

    Full Text Available Human development activities as water reservoir construction have great impact on the vegetation, thus changing its floristic, as well as its structure and ecology functions. Parana Pine Forest alongside with grasslands have been highly modified and in particular to the last one, there are few works related to its restoration. In the border of Irai water reservoir (Metropolitan Region of Curitiba, PR, where occurs grasslands associated to the Parana Pine Forest, where it were established
    tree plantations aiming rescue tree vegetation lost due to the flooding. Inside these plantations, an experiment was established to compare growth and survival of eight local native species in 12 months, in single species plots and under the same environmental conditions. Results for the species Escallonia  montevidensis, Lafoensia pacari, Lithraea molleoides, Luehea divaricata, Mimosa scabrella, Podocarpus lambertii and Vitex megapotamica presented very undesirable attributes, where height ranged between 10 cm and 33 cm, diameter ranged between 2.5 mm a 6.6 mm and survival percentage was between 9.1 and 66. 7 . It was possible to claim these results to water deficit, soil with low base saturation, to delayed planting
    and to high plant evapotranspiration. Actions dealing with restoration must consider limits and possibilities concerning each phytoecological region and proper restoration techniques as well.A diversidade e a intensidade das atividades antrópicas implicam em grandes impactos sobre a vegetação,
    alterando sua florística, estrutura e funções. A Floresta Ombrófila Mista, assim como as estepes, estão fortemente descaracterizadas, tendo essas últimas poucas e incipientes informações sobre recuperação ambiental. Às margens da Represa do Iraí (Região Metropolitana de Curitiba, PR, em área de estepe associada à Floresta Ombrófila Mista, foram realizados plantios com espécies arbóreas como forma de dar início

    The current conceptual models of the Guarany Aquifer System (GAS), found in Galboa et al. (1976), Fraga (1992); Campos (1994), Araujo et al. (1995), Rosa Filho et al. (1998) and Campos (2000), are in regional scale, taking only intoaccount the aquifer stratigraphic characteristics, showing the Piramboia and Botucatu Formations gently dipping under the Serra Geral Formation. This model represents the aquifer like an almost homogeneous and isotropic layer, desregarding local influences caused by fauts and intrusive bodies on the groundwater flow or on the water volume stored in the aquifer, as quoted by Sinelli et al. (1984). The GAS shows many structural conditioning, with highligts to the depocenters of Serra Geral Formation, reactivation of faulting systems, the uplift of the present basin s borders and the activation of the Rio Grande and Ponta Grossa Arches (Araujo et al., 1995). Regarding the structural control due to the Ponta Grossa Arch, it is worthwhile to point out the ocurrence along the mentioned arch, of innumerous diabase dykes predominately striking NW (Ferreira 1982a,b).The dykes and regional geological structures (faultings) play an important role on the structural compartimentation of the GAS. The strategy for the GAS exploitation, inside Parana State, must involve technical, scientific (geology, geophysics, hydrochemistr y and isotopic studies) and socio-economic approaches, in order to select the favourable targets for groundwater withdraw and, simultaneously, allow a proper management that result in a good balance between water production and use and protection of the GAS. Therefore, the knowledge of local geological factors controling the aquifer hydrodynamic (flow pattern, volume of stored water, well yieldings and water quality) besides its geometric compartimentation (unities with different hydrodynamic behaviour), will contribute to the development of a conceptual qualitative model to be used as a tool for the SAG mangement. The results of

    Full Text Available Exemplares de Bryconamericus iheringii (Boulenger, 1887 coletados nos riachos Cambé, Taquari, Água da Floresta e Baroré, localizados na bacia do rio Tibagi, Estado do Paraná, foram analisados para verificar sua dieta. As coletas foram padronizadas em todos os riachos. Os conteúdos estomacais foram analisados qualitativa e quantitativamente. Verificou-se que a dieta de B. iheringii nos quatro riachos consistiu de itens alimentares que variaram em número, e os de maior importância foram: restos vegetais e detrito, no Cambé;detrito, no Taquari; algas filamentosas e restos vegetais, no Água da Floresta; detrito e restos de insetos, no Baroré. O comportamento de mudar de estratégia, de generalista para especialista, e de utilizar o item detrito, que é capturado apenas no fundo, como principalalimento, podem ser indicadores que trechos de riachos com águas mais lentas e profundas não são preferenciais para B. iheringii, como também não são para alguns grupos de insetos aquáticos que servem como seu alimento. Individuals of Bryconamericus iheringii (Boulenger, 1887, collected in the streams of Cambé, Taquari, Água da Floresta and Baroré, which belong to the Tibagi river basin (Parana Sate, Brazil, were analyzed for the purpose of diet study. The collection procedures were standardized in every stream. The stomach contents of the individuals were analyzed qualitative and quantitatively. The food items consumed by the species varied in number, and the main food item consumed differed in each stream. Thus, it was found: vegetable remains and debris, in Cambé; debris, in Taquari; filamentous algae and vegetable remains, in the Água da Floresta; and debris and remains of insects, in Baroré stream. The behavior shift from generalist to specialist strategy as well as the use of detritus as the main food, which can only be found in the river bottom, can indicate that stretches of streams with slower and deeper waters are not preferred

    Measurement of skull ossification patterns is a standard method for aging various mammalian species and has been used to age Russian, Californian, and Alaskan sea otter populations. Cementum annuli counts have also been verified as an accurate aging method for the Alaskan sea otter population. In this study, cementum annuli count results and skull ossification patterns were compared as methods for aging the northern sea otter (Enhydra lutris kenyoni) population in Washington State. Significant agreement was found between the two methods suggesting that either method could be used to age the Washington population of otters. This study also found that ossification of the squamosal-jugal suture at the ventral glenoid fossa can be used to differentiate male subadults from adults. To assist field biologists or others without access to cementum annuli or skull ossification analysis techniques, a suite of morphologic, physiologic, and developmental characteristics were analyzed to assess whether a set of these more easily accessible parameters could also predict age class for the Washington population of otters. Tooth condition score, evidence of reproductive activity in females, and tooth eruption pattern were identified as the most useful criteria for classifying Washington sea otters as pups, juveniles, subadults, or adults/aged adults. A simple decision tree based on characteristics accessible in the field or at necropsy was created that can be used to reliably predict age class of Washington sea otters as determined by cementum annuli.

A quantidade de resíduo da avicultura, produzido no ano de 2001, foi de 382.021 toneladas. Esse resíduo animal é uma importante forma de biomassa, a qual pode ser utilizada como fonte primaria para geração de energia elétrica. Com a queima direta desse resíduo, a energia térmica que pode ser produzida é de 140.500 kJ/s; apenas uma parte dessa energia pode ser convertida em trabalho mecânico e potência elétrica em um turbo-gerador a vapor, essa potência elétrica foi calculada em 50.700 kW. A produção do resíduo da avicultura é sazonal de forma que a potência instalada de uma usina termoelétrica queimando esse tipo de biomassa foi estimada em 8.900 kW, considerando o fator de economia de escala. Para a visualização espacial da produção de resíduos e do potencial técnico de energia nos municípios da Mesoregião Oeste do Paraná foi utilizado o Sistema de Informação Geográfica (SIG Arc View 3.2.This work reports the study of the energy potential from poultry-litter in the municipal districts of the West Region of Parana State, Brazil. The amount of waste produced during the year 2001 was 382.021 tons. The animal waste is an important biomass form, which may be used as a primary resource for electric power generation. The thermal energy with its direct burning that can be produced is 140.500 kJ/s;since only a part of that energy can be converted into mechanical work and electric power in a steam turbine-electric-generator, the electric power was estimated at 50.700 kW. The production of poultry-litter is seasonal because the installed power of a thermoelectric plant that burns this kind of biomass was estimated to be around 8.900 kW, considering the economy scale factor.

    The Pien area presents the major geotectonic domains separated by the Pien Shear Zone (PSZ). The northern one is the Rio Pien Granite-Mylonitic Suite composed by calc-alkaline granitoids of Neoproterozoic age. The southern domain is represented by the Amphibolite-Granulite where high grade metamorphism took place at the end of paleoproterozoic time. Considering the identified lithotypes, their geochemical affinity (particularly the Ti, Cr, Ni and REE content) and the geological context observed in the area, a geotectonical model of active continental margin related to subduction SSZ (Supra-Subduction Zone) is proposed. K-Ar on plagioclase from gabbronorites gave Neoproterozoic ages although Sm-Nd whole rock isochron yielded Paleoproterozoic ages. Based in geochemical data, it is proposed that the biotite gneiss and biotite-amphibole-gneiss which occur near the PSZ have a shoshonitic to high-K calc-alkaline features which are characteristic of active continental margins. K-Ar on biotite extracted from these rocks, gave Neoproterozoic ages. The available radiometric data for the Rio Pien mylonitic granitoids show that between 650-595 Ma the generation, deformation and cooling below the isotherm of 250 deg C occurred. On the other hand, the geochronological data for the Agudos do Sul Massif are in the 590-570 Ma interval showing its younger generation. The Sr{sup 87} / Sr{sup 86} initial ratios for both granitoids suggest more involvement of the continental crust in the origins of Agudos do Sul granitic Massif. The analyses of the entire set of the available data for the Pien area allows the suggestion of a geotectonic scenery related to the evolution of an active continental margin during the collages associated to the Brasiliano Cycle 201 refs., 130 figs., 6 tabs., 2 maps

    Full Text Available The aim of this study was to conduct a serological survey for Lyme diseases, brucellosis, leptospirosis and toxoplasmosis and identify the risk variables related to these zoonoses in humans living in the rural area of Jataizinho, state of Parana, Brazil. A total of 63 rural properties were surveyed. Additionally, 207 serum samples collected from these rural area inhabitants were tested for indirect immunofluorescence (IFI and western blots (WB were performed to detect Borrelia burgdorferi (sensu lato; a tamponated acidified antigen test (AAT and 2-mercaptoethanol (2-ME were used to detect antibodies of Brucella abortus; the microscopic agglutination test (MAT was carried out to detect antibodies anti-Leptospira spp. and IFI was used to find antibodies of Toxoplasma gondii. Two of the samples (0.96% were reactive for Lyme borreliosis, three (1.4% for brucellosis, 25 (12.1% for leptospirosis and 143 (69.1% for toxoplasmosis. Although the town of Jataizinho has a human development index (IDH that was considered to be average (0.733 in the state of Parana, the low social, economic and cultural conditions of the population from small rural properties have resulted in lack of basic information on animal health and direct or indirect contact with the various species of domestic animals, wildlife and ticks have probably contributed to the prevalence levels found. These results show the need for additional regional studies in order to determine the epidemiological characteristics of these diseases as well as their respective vectors and reservoirs so that effective prophylaxis can be administered in the human population.

The objective of this research was to indicate zones with lower climatic risk for production of these crops in the state of Paraná, Brazil, using climatic risk analysis and agronomic data. Historical data of 32 weather stations of IAPAR were analyzed to estimate and map the risks of late frost and the average totals of chilling hours above 7.2ºC accumulated from May to September. The regions in which the last frost occurs before flowering and with the total chilling hours suitable to the cultivars needs were considered apt. Most of the north, west and the coast of Paraná do not have enough chilling hours. The areas located in the south with altitudes above 800 m are the most suitable. Within the apt areas eight zones were classified according to the chilling requirements of peaches and nectarine varieties and climatic conditions of each region: zone 1 (75 to 150 hf; zone 2 (150 to 200 hf; zone 3 (200 to 250 hf; zone 4 (250 to 300 hf; zone 5 (300 to 350 hf; zone 6 (350 to 400 hf, zone 7 (400 to 450 hf and zone 8 (> 450 hf. The zones with lower altitude and higher temperatures accumulate less chilling hours from May to September and are indicated for cultivars with lower chilling requirement. The zones with higher altitudes and high chilling accumulation are suitable for varieties with high chilling requirements (> 400 chilling hours. The last frost is likely to occur in the last ten days of August in the colder regions and do not cause damages to suitable varieties of peaches and nectarine. The results obtained in this work support the adoption of policies to foment these crops in the state of Paraná with low risk.

    Full Text Available Com o objetivo de avaliar a distribuição espacial e temporal da comunidade de cianobactérias no perifíton, bem como os fatores abióticos que atuaram sobre este grupo, foram feitas amostragens em dois reservatórios, Segredo e Iraí, ambos na bacia do rio Iguaçu, Paraná. As coletas foram realizadas no verão (abril e no inverno (setembro de 2002, nas regiões superior, intermediária e inferior dos reservatórios. Foram inventariadas 66 espécies de cianobactérias, sendo que Iraí apresentou 50 táxons e Segredo 38. O reservatório de Iraí apresentou densidade de cianobactérias (25 a 101 x ind. 103 cm-2 maior do que aquelas observadas para Segredo (1 a 14 x ind. 103 cm-2. Acredita-se que a composição e a densidade cianobactérias foram resultados de uma combinação de fatores, em que as diferenças nas variáveis abióticas (nitrogênio, fósforo e temperatura ao longo do eixo rio-barragem e nas diferentes estações, a morfometria e a hidrodinâmica foram consideradas preponderantes.In order to evaluate spatial-temporal distribution of periphytic cyanobacterial community, as well as the influence of abiotic factors on these organisms, samples were collected in two reservoirs: Segredo and Iraí, located within the Iguaçu river basin, State of Paraná. Samplings were collected in summer (April and winter (September, 2002, in upper, intermediary and lower regions. A total of 66 cyanobacterial species were registered, with fifty species occurring in Iraí Reservoir and thirty-eight in Segredo Reservoir. Iraí showed higher values of cyanobacteria density (25 to 101 x ind 103 cm-2 when compared with Segredo (1 to 14 x ind 103 cm-2. We believe that cyanobacteria composition and density resulted from several factors, with preponderance of the effects of abiotic variables differences (nitrogen, phosphorus and temperature along the longitudinal axis and along the different seasons, as well as the morphometric and hydrodynamic effects.

    Full Text Available Com o objetivo de debater a problemática que envolve a inclusão do aluno surdo no ensino regular, esse estudo se propõe a analisar aspectos envolvidos em tal problemática a partir da visão de um grupo de professores. Para tanto, foi aplicado questionário junto a 36 professores inseridos na Rede Pública do Ensino Fundamental e Médio do Estado do Paraná. A análise dos dados evidencia que as principais dificuldades citadas ora relacionam-se aos próprios professores - à falta de conhecimento acerca da surdez, à dificuldade de interação com o surdo, ao desconhecimento de LIBRAS -, ora aos sujeitos surdos - a própria surdez e a dificuldade de compreensão que tais sujeitos apresentam na ótica dos professores. Cabe ressaltar que os professores, sujeitos dessa pesquisa, não relacionam as suas dificuldades para ensinar com as dificuldades de seus alunos para aprender, como se o desconhecimento dos professores acerca da surdez, por exemplo, não tivesse implicações diretas na aprendizagem dos surdos. Conclui-se que a inclusão de surdos no ensino regular significa mais do que apenas criar vagas e proporcionar recursos materiais, é necessário que a escola e a sociedade sejam inclusivas, assegurando igualdade de oportunidades a todos os alunos e contando com professores capacitados e compromissados com a educação de todos.Since this study aims to discuss the placement of deaf students in regular schools, we intend to analyze various aspects pertaining to such issues from the perspective of a group of teachers of deaf students. We applied a questionnaire to 36 teachers working in public schools in elementary, middle and high school levels in the state of Paraná. The data analysis showed that the main difficulties mentioned were related either to the teachers themselves or to their students. Teacher related issues ranged from the teachers' lack of knowledge about deafness, or to problems concerning interaction with the deaf and lack

    Excavations at the site of Taraco in the northern Titicaca Basin of southern Peru indicate a 2,600-y sequence of human occupation beginning ca. 1100 B.C.E. Previous research has identified several political centers in the region in the latter part of the first millennium B.C.E. The two largest centers were Taraco, located near the northern lake edge, and Pukara, located 50 km to the northwest in the grassland pampas. Our data reveal that a high-status residential section of Taraco was burned in the first century A.D., after which economic activity in the area dramatically declined. Coincident with this massive fire at Taraco, Pukara adopted many of the characteristics of state societies and emerged as an expanding regional polity. We conclude that organized conflict, beginning approximately 500 B.C.E., is a significant factor in the evolution of the archaic state in the northern Titicaca Basin.

    The statistical and geometrical properties of fracture systems were obtained by analyzing remote sense images and outcrop data, in the Region of Guartela Canyon, in the central-eastern of Parana State. The probability distributions of fractures, with their parameters and attributes, were obtained through extensive statistical exploration of data. These parameters were used as input data for generating 3-D stochastic fractures models through the 'discrete fracture network - DFN' method. The modeling is performed by using the code FRED. To study the persistence of statistical parameters in multiple scales were used remote sensing images (SRTM, Landsat TM7 and aerial photos), covering a scale range from outcrops (few meters) to basin scales (hundreds of kilometers). The results indicated the presence of power-law (fractal) statistics for the spatial and size distributions. Fractals distributions were found for all sets studied, in some cases with different fractal exponents. The implications of fractal behavior for the generation of discrete fracture network, and consequently for the hydraulic properties, are briefly discussed. (author)

    One of the requirements for the existent of economic deposits of hydrocarbons is that the organic matter has undergone adequate thermal maturation. Several techniques have been proposed in order to quantity the catagenetic state of kerogen, and the Lopatin-Waples methodology permits quantification at any past time and does not require laboratory tests on samples of the material. For this reason it is an useful techniques for predicting mature zones using as basic information the thermal and subsidence histories of each stratum. Lopatin`s technique was applied to the Parana basin, with McKenzie`s crustal stretching model fitted to the data of 18 wells, and the areas predicted as mature for oil and/or gas were in good agreement with the field results. The technique predicted oil phone areas at the east border of the basin for the Ponta Grossa and Irati formation, and also that most of the thermal maturation occurred after the basalt flows of the Cretaceous period.

    This study aims to to evaluate the possible health effects on workers in a underground coal mining that were exposed to radon and its decay products without the knowledge of the exposure risk. We established a historical cohort of workers in this mining which included 2856 workers, 1946 underground workers and 910 surface workers, and was carried out a retrospective tracking of mortality in this cohort between 1979 and 2002. Through multiple strategies for monitoring, involving several national institutions, was possible to trace the vital status of 92% of the cohort and 100% of the causes of deaths. The results showed that employees of underground coal mining in Parana had a risk of mortality from lung cancer higher than might be expected to the male population of the state of Parana, observing an increase in risk with the time of underground service. However, this increase in mortality from lung cancer was not observed for surface workers. Among several carcinogenic agents present in the mine environment, radon gas and its decay products can be identified as the major cause for this increase in risk of lung cancer for these workers, once other epidemiological studies in coal mining, which have no risk of exposure to radon, do not present an increased of mortality risk from lung cancer.

    1985-01-01

    The mangetotelluric geophysical method has been used effectively as a hydrocarbon exploration tool in the intracratonic Parana basin of South America. The 1-2 km thick surface basalts and buried diabase sills pose no problem for the magnetotelluric method because the natural electromagnetic fields used as the energy source pass easily through the basalt. Data for the regional study were taken on six profiles with sounding spaced 8 to 15 km apart. The magnetotelluric sounding data outline a linear uplift known as the Ponta Grossa arch. This major structural feature cuts across the northeast-trending intracratonic basin almost perpendicularly, and is injected with numerous diabase dikes. Significant electrical contrasts occur between the Permian sediments and older units, so that magnetotelluric measurements can give an indication of the regional thickness of the Permian and younger sediments to aid in interpreting hydrocarbon migration patterns and possible trap areas.

    Full Text Available This study examines the socioeconomic features that underpin the expansion of groundwater-dependent irrigation in Northern State, Sudan. Groundwater development in the region serves as an economic lifeline given the poor Nile-based irrigation infrastructure and future changes in Nile hydrology. Groundwater-dependent irrigation is found to be expanding in previously uncultivated regions increasingly distant from the Nile. The study finds these historically marginal lands are targeted for capital-intensive agricultural projects because landholding patterns in traditionally cultivated areas preclude new large developments and improved infrastructure has lowered farming costs in distant terraces. Private companies and large landholders have a history of successful agricultural ventures in Northern State and are reliant on easily accessible and reliable groundwater resources for these new farms.

    2006-01-01

    Based on a case study of health integration in Canadian northern EA, this paper further demonstrates the lack of consistent integration of health in EA practice. A survey was administered to northern EA and health practitioners, administrators and special interest groups to assess current northern health assessment practices, the scope of health in EA, EA performance with regard to health assessment and the perceived barriers to health integration. Results suggest that health is currently recognized as an important component of northern EA and is addressed in the majority of cases; however, health is addressed primarily during the pre-decision stages of EA and less often during post-decision follow-up and monitoring. Moreover, when health is addressed, attention is limited to the physical components of health and health impacts due to physical environmental change, with considerably less attention given to the social aspects of health. Results also suggest dissent between EA practitioners, health practitioners and other interests concerning the overall state of health in EA; however, there is consensus on the key challenges to improved integration, namely differences in understanding of the scope of health and expectations of EA to assess health impacts; limited coordination between EA and health practitioners; limited scope and requirements of current EA legislation for health assessment; and the lack of supporting EA methods and frameworks

    This study relates tectonic features to hydrochemistry properties in order to show an example where the Guarany Aquifer behaves like a closed compartiment. This situation can be used as a model to other localities with similar geological structures where the aquifer is not recharged by modern waters, therefore, groundwater withdrawal from deep wells depletes the aquifer turning its exploitation not recommended. This study area was located inside the limits of the Ponta Grossa Arch, especially by the the Rio Alonzo and Sao Jeronimo-Curiuva lineaments. Among the waters that had been already classified in Sao Paulo and Parana States (Brazil), predominate the calcium-bicarbonate and sodiumbicarbonate types and the characteristic of the water in this particular case is sodiumsulfate- chloride type with TDS above 1000 mg/L

    Full Text Available The Kunduz River Valley of northern Afghanistan and the Vakhsh River Valley of southern Tajikistan followed what initially appear to be vastly different trajectories. Despite these two adjacent areas having had much in common throughout many periods of history, the present-day region of northern Afghanistan was eventually taken under the control of the Afghan state while the areas north of the Amu Darya and Panj River were to become part of the Soviet Union. However, instead of a divergent course of development and state-building, these two regions were subjected to very similar patterns of agricultural development and migration policies. “Empty” areas were to be populated, by force if necessary, wetlands were to be drained for agriculture, and cotton farming was to become pre-eminent. The end result in both areas was the creation of a socially diverse and economically significant region that was fully integrated into the modern state’s economy and politics. This article analyzes and compares the motives and implementation of the state-building projects in both of these now domestically important regions and finds remarkable similarities despite the obvious differences in the structure of the Afghan and Soviet states.

In the herd, at least six sows and her litters were evaluated from the birth up to weaning by four objetive variables (diarrhoea in the suckling, mortality rate, weight variation coefficient at weaning and average daily weight gain in the period, and were observed sixteen explainatory variables: (daily thermal amplitude, % area of the windows in the pant, pen 's area, corporal status of the sow, creep presence, farrowing assistance, weight at birth, onfalite presence, internal minimal temperature in the plant, litter size at birth, colibacilosis vaccination, sows per plant, coletive suckling, roof presence in the plant, intestinal parasites presence and sanitary breack utilization. The variables were evaluated by the ECOSUI program developed by EMBRAPA/CNPSA. The main risk factors observed were: high internal minimal temperature, high thermal amplitude, sanitary break absence, roof absence, high sows per plant, insufficient pen's area, onfalite and intestinal parasites presence and colibacilosis vaccination absence (founded in 50% of farms. The rates of the objetive variables were insatisfatory. The relation of diarrhoea presence was 8/18; to mortality rate the relation was 5/17; to weight variation coefficient, 0/18; and to the average daily weight gain, 9/17. The results indicate that the preventive veterinary medicine is very importam to reduce these risk factors to improve the suckling pigs performance.

    The last major tectonic event in the northern Gulf Coast of the United States is Mesozoic continental rifting that formed the Gulf of Mexico. This area also experienced igneous activity and local uplifts during Cretaceous. To investigate lithosphere evolution associated with the rifting and igneous activity, we construct Rayleigh and Love wave phase velocity models at the periods of 6 s to 125 s in the northern Gulf Coast from Louisiana to Alabama including the eastern Ouachita and southern Appalachian orogeny. The phase velocities are derived from ambient noise and earthquake data recorded at the 120 USArray Transportable Array stations. At periods below 20 s, phase velocity maps are characterized by significant low velocities in the Interior Salt Basin and Gulf Coast Basin, reflecting the effects of thick sediments. The northern Louisiana and southern Arkansas are imaged as a low velocity anomaly in Rayleigh wave models but a high velocity anomaly of Love wave at the periods of 14 s to 30 s, indicating strong lower crust extension to the Ouachita front. High velocity is present in the Mississippi Valley Graben from period 20 s to 35 s, probably reflecting a thin crust or high-velocity lower crust. At longer periods, low velocities are along the Mississippi River to the Gulf Coast Basin, and high velocity anomaly mainly locates in the Black Warrior Basin between the Ouachita Belt and Appalachian Orogeny. The magnitude of anomalies in Love wave images is much smaller than that in Rayleigh wave models, which is probably due to radial anisotropy in the upper mantle. A 3-D anisotropic shear velocity model will be developed from the phase velocities and will provide more details for the crust and upper mantle structure beneath the northern Gulf of Mexico continental margin.

    Full Text Available Background: In order to provide appropriate advice to the patient at the time of dispensing and over-the-counter (OTC medication counseling, community pharmacists need access to current and reliable information about medicines. Brazilian pharmacists have assumed new functions such as prescribing medication, in a dependent model, based in protocols. Objective: To examine the practice of community pharmacists in a Brazilian State, focusing on OTC recommendation. Method: A cross-sectional survey of community pharmacists in a state of Brazil was conducted from October 2013 to January 2014, with data collection through a pre-piloted self-administered anonymous survey via Survey Monkey® platform. Following ethical approval, the online instrument was sent to 8,885 pharmacists registered in Parana State, Brazil, focusing on professionals working in community pharmacies. The questionnaire assessed the community pharmacy setting, the search for information, the knowledge of the evidence-based practice, the important factors to consider when recommending an OTC medicine, and the pharmacist prescribing. Responses were imported into SPSS® (version 22.0 for analysis. Nonparametric tests were used to assess the association between responses and demographic information with a significance level less than 5% (p<0.05. Results: Of the pharmacists, 97.4% dispensed medications and counseled patients for a median of six hours per day. Product's efficacy (97% and adverse effects (62.3% were the most important factors taken into account when counseling a nonprescription medicine. Few pharmacists knew the meaning of terms related to evidence-based health. Most respondents agreed that pharmacists have the necessary training to prescribe. Conclusion: Over-the-counter medication counseling is a daily practice among Brazilian pharmacists. Learning needs exist for community pharmacists in relation to evidence-based practice. Thus, sources of information with good evidence

    The Deciduous Complex that occurs in northern Minas Gerais State, Brazil, raises questions about the floristic affinities of these formations in relation to neighboring phytogeographical domains. Little is known about the identity of the seasonal forest formations that comprise this complex, or about its relationships to abiotic components, such as soils, topography and climate. This study aimed to recognize the patterns of floristic similarity of all studied fragments of dry forest of northern Minas Gerais with soil and climate attributes, based on the available database. Cluster analysis indicated the existence of two floristic groups that had clear associations with either the Koppen's BSh (semi-arid) or Aw (seasonal tropical) climates. Likewise, the subdivisions of these groups showed clear associations with the dominant soil classes in the region. The Red-Yellow Latosol is the dominant soil classes in the BSh climatic domain, seconded by alluvial areas associated with Fluvic Neosols. The Aw domain comprised a much varied set of soils: Nitosols, Argisols, Cambisols and Litholic Neosols, most derived from the Bambuí limestone/slate formation. The ecotonal nature of northern Minas Gerais State provides a complex interaction between the flora of neighboring phytogeographical domains. This, allied to pedogeomorphological factors, allowed a better understanding of the effects of late Quaternary climate changes for the Deciduous Complex evolution. We conclude that the Latosols under present-day semi-arid climates (BSh) are relicts of former wetter climates, during which humid forest (semideciduous) expansion took place. Later, these semideciduous forests were subjected to a much drier climate, when selection for deciduousness led to the present-days Deciduous Complex scenario.

    2011-01-01

    This paper describes the natural radioactivity of groundwater occurring in sedimentary (Bauru and Guarani) and fractured rock (Serra Geral) aquifer systems in the Parana sedimentary basin, South America that is extensively used for drinking purposes, among others. The measurements of gross alpha and gross beta radioactivity as well the activity concentration of the natural dissolved radionuclides 40 K, 238 U, 234 U, 226 Ra, 222 Rn, 210 Po and 210 Pb were held in 80 tubular wells drilled in 21 municipalities located at Sao Paulo State and its border with Mato Grosso do Sul State in Brazil. Most of the gross alpha radioactivity data were below 1 mBq/L, whereas values exceeding the gross beta radioactivity detection limit of 30 mBq/L were found. The radioelement solubility in the studied systems varied according to the sequence radon>radium>other radionuclides and the higher porosity of sandstones relatively to basalts and diabases could justify the enhanced presence of dissolved radon in the porous aquifer. The implications of the data obtained in terms of standards established for defining the drinking water quality have also been discussed. The population-weighted average activity concentration for these radionuclides was compared to the guideline value of 0.1 mSv/yr for the total effective dose and discussed in terms of the choice of the dose conversion factors. - Highlights: → Integration of distinct radiometric data acquired in groundwaters. → Radiation dose in important hydrological resources in South America. → Contribution of 226 Ra for the more accentuated radiation dose in aquifers. → Dose factors for Rn and generation of values exceeding the maximum of 0.1 mSv/yr.

    The northern Adriatic Sea ecosystem dynamics is simulated using the coupling of the BFM (Biogeochemical Flux Model) with the NEMO (Nucleus for European Models of the Ocean) model. The modeling system is implemented at very high horizontal (~800 m) and vertical (95 z-level) resolution and is nested with a coarser scale Adriatic/Mediterranean model. Simulation in hindcast and projection mode are being executed and are aimed to evaluate the ecosystem attributes (vigor, organization, resilience), in order to understand the ecosystem state of the basin with respect to the so-called "Good Ecosystem State" (GES) as defined by the EU-MSF9 Directive. Skill of the model in replicating integrated environmental indices such as the EU-EEACS1023+ is also investigated. Finally the model is also open to an off-line coupling with an higher trophic level (HTL) model.

    In recent times, the State of New Jersey (USA) has been making attempts at promoting recycling as an environmentally friendly means of attaining self-sufficiency at waste disposal, and the state has put in place a 50% recycling target for its municipal solid waste stream. While the environmental benefits of recycling are obvious, a recycling program must be cost effective to ensure its long-term sustainability. In this paper, a linear programming model is developed to examine the current state of recycling in selected counties in Northern New Jersey and assess the needs to achieve the state's recycling goal in these areas. The optimum quantities of waste to be sent to the different waste facilities, which include landfills, incinerators, transfer stations, recycling and composting plants, are determined by the model. The study shows that for these counties, the gap between the current waste practices where the recycling rate stands at 32% and the state's goal can be bridged by more efficient utilization of existing facilities and reasonable investment in expanding those for recycling activities

    Full Text Available We carried out a study on the anurofaunal community from an Atlantic Forest fragment (Monte Verde mountains and the surrounding area in Cambuci municipality, Rio de Janeiro State, Brazil, which constitutes one of the largest fragments remaining in the largely deforested landscape of the northern portion of the State. We combined three sampling methods: plot sampling, transects and pit-fall traps. We recorded twenty species of amphibians, of which only eleven were found within the forest fragment (and five of these also occurred in the surrounding matrix. Two of the species recorded in the present study (Crossodactylus sp. and Ischnocnema cf. parva may represent undescribed taxa. Our records expand the distribution range of one species (Scinax trapicheiroi to the north, and fill a geographic distribution gap for another one (Ischnocnema oea. The estimated overall density of frogs living in the leaf litter of the fragment (based on results of plot sampling was 3.1 individuals/100 m², with Haddadus binotatus being the most abundant species (2.4 individuals/100 m². Comparisons of our data with those of other studies suggest that anuran communities in forest fragments ca. 1,000 ha or smaller may be severely limited in their richness, and often include a large proportion of species tolerant to open areas, such as many hylids. Our results show the importance of increasing knowledge about the anurofaunal community of the northern portion of the State of Rio de Janeiro and preserve the forest remnants that still exist in the region.

    Full Text Available Purpose: This study investigates employers’ perspective towards employing people with disabilities  in the northern states of Peninsular Malaysia. The research also endeavoured to identify factors that promote or hinder gainful employment of people with disabilities in Malaysia.Method: The data was collected through postal questionnaires distributed to several types of industries in the northern region of Malaysia.Results: The results indicated that most of the employers are in favour of employing persons with disabilities. However, very few have such enabling policies, or a mechanism to handle issues related to persons with disabilities, or a built environment which is fully accessible to persons with disabilities.  They are also concerned about the  ability of workers with disabilities to comprehend and follow orders, as well as the costs involved in employing and training them. These results imply that if employers  want to fulfil their intentions of recruiting persons with disabilities, a lot has to be done to employ and sustain them in their jobs.Key words: Employment, People with Disabilities, Malaysiadoi 10.5463/DCID.v22i2.28

    Full Text Available Investigation of the aetiology of viral meningitis in Brazil is most often restricted to cases that occur in the Southern and Southeastern Regions; therefore, the purpose of this study is to describe the viral meningitis cases that occurred in state of Pará, Northern Brazil, from January 2005-December 2006. The detection of enterovirus (EV in cerebrospinal fluid was performed using cell culture techniques, RT-PCR, nested PCR and nucleotide sequencing. The ages of the 91 patients ranged from 60 years old (median age 15.90 years. Fever (87.1%, headache (77.0%, vomiting (61.5% and stiffness (61.5% were the most frequent symptoms. Of 91 samples analyzed, 18 (19.8% were positive for EV. Twelve were detected only by RT- PCR followed by nested PCR, whereas six were found by both cell culture and RT-PCR. From the last group, five were sequenced and classified as echovirus 30 (Echo 30. Phylogenetic analyses revealed that Echo 30 detected in Northern Brazil clustered within a unique group with a bootstrap value of 100% and could constitute a new subgroup (4c according to the phylogenetic tree described by Oberste et al. (1999. This study described the first molecular characterization of Echo 30 in Brazil and this will certainly contribute to future molecular analyses involving strains detected in other regions of Brazil.

    The North Pacific Acoustic Laboratory (NPAL) Philippine Sea experiment deployed a variety of instruments in the northern Philippine Sea during April 2010 through April 2011, including 6 acoustic transceivers for reciprocal measurements of travel times between instruments. Five of the transceivers were moored in a pentagon approximately 660 km in diameter with the sixth transceiver mooring in the center. A seventh mooring approximately 130 km northwest of the center supported a Distributed Vertical Line Array (DVLA) which carried 149 acoustic receivers with thermistors covering the depths between 200 m and 5500 m. The goals of the experiment included studying the energetic westward-propagating eddies which travel through the region, their effect on underwater sound propagation, and the impact of acoustic measurements on estimates of the time-evolving ocean state. Observed travel-time time series were compared with travel times computed from ocean state estimates made using an eddy-active regional implementation of the MITgcm that were constrained by satellite sea surface height and sea surface temperature observations and by temperature and salinity profiles from Argo, CTDs, and XBTs but not by the acoustic data. The similarities cross-validate the state estimates, while the differences provide a simple estimate of the novel information present in the travel times. The ocean state estimates were then re-computed to fit the acoustic travel times as integrals of the sound speed, and therefore temperature and salinity, along the ray paths. Over the approximately 1 year experiment, the state estimate was able to match the travel times within their error bars and did not significantly increase the misfits with the other observations. Comparisons of the state estimates with and without the travel-time data showed significant changes to the temperature and salinity were made to fit the acoustic observations. The state estimates using the acoustic data compare favorably

    The Blue Peacock Bass (Cichla piquiti), native to the Tocantins-Araguaia river basin of the Amazon system, was introduced into the basin of the Paranaíba River, Paraná River system. Cachoeira Dourada reservoir is one of a series of dams on the Paranaíba River in central Brazil, where this fish has become established. A study of its feeding spectrum, combined with information about its reproductive characteristics and population structure, would enable the current state of this species in the reservoir to be assessed and might provide useful data for the management of other species native to this habitat. This study showed that the peacock bass has no predators or natural competitors in the reservoir and that reproduces continuously, with high reproductive rates, and has a smaller median length at first maturity (L50) than other species of Cichla. Its successful establishment in habitats strongly affected by human activity should cause changes in the whole structure of the local fish communities. Nonetheless, in this reservoir, there appears to be some sharing of the functions of this species with native carnivorous fish, a situation that may be sustained by the presence of a wide variety of foraging fish.

  1. Grassland to shrubland state transitions enhance carbon sequestration in the northern Chihuahuan Desert.

    The replacement of native C4 -dominated grassland by C3 -dominated shrubland is considered an ecological state transition where different ecological communities can exist under similar environmental conditions. These state transitions are occurring globally, and may be exacerbated by climate change. One consequence of the global increase in woody vegetation may be enhanced ecosystem carbon sequestration, although the responses of arid and semiarid ecosystems may be highly variable. During a drier than average period from 2007 to 2011 in the northern Chihuahuan Desert, we found established shrubland to sequester 49 g C m(-2) yr(-1) on average, while nearby native C4 grassland was a net source of 31 g C m(-2) yr(-1) over this same period. Differences in C exchange between these ecosystems were pronounced--grassland had similar productivity compared to shrubland but experienced higher C efflux via ecosystem respiration, while shrubland was a consistent C sink because of a longer growing season and lower ecosystem respiration. At daily timescales, rates of carbon exchange were more sensitive to soil moisture variation in grassland than shrubland, such that grassland had a net uptake of C when wet but lost C when dry. Thus, even under unfavorable, drier than average climate conditions, the state transition from grassland to shrubland resulted in a substantial increase in terrestrial C sequestration. These results illustrate the inherent tradeoffs in quantifying ecosystem services that result from ecological state transitions, such as shrub encroachment. In this case, the deleterious changes to ecosystem services often linked to grassland to shrubland state transitions may at least be partially offset by increased ecosystem carbon sequestration. © 2014 John Wiley & Sons Ltd.

  2. Projected climate change effects on winterkill in shallow lakes in the northern United States

    Each winter, hundreds of ice-covered, shallow lakes in the northern US are aerated to prevent winterkill, the death of fish due to oxygen depletion under the ice. How will the projected climate warming influence winterkill and the need to artificially aerate lakes? To answer this question, a deterministic, one-dimensional year-round water quality model, which simulates daily dissolved oxygen (DO) profiles and associated water temperatures as well as ice/snow covers on lakes, was applied. Past and projected climate scenarios were investigated. The lake parameters required as model input are surface area, maximum depth, and Secchi depth as a measure of radiation attenuation and trophic state. The model is driven by daily weather data. Weather records from 209 stations in the contiguous US for the period 1961--1979 were used to represent past climate conditions. The projected climate change due to a doubling of atmospheric CO{sub 2} was obtained from the output of the Canadian Climate Center General Circulation Model. To illustrate the effect of projected climate change on lake DO characteristics, the authors present herein DO information simulated, respectively, with inputs of past climate conditions and with a projected 2 x CO{sub 2} climate scenario, as well as differences of those values. Specific parameters obtained were minimum under-ice and lake bottom DO concentration in winter, duration of under-ice anoxic conditions and low DO conditions, and percentage of anoxic and low DO lake volumes during the ice cover period. Under current climate conditions winterkill occurs typically in shallow eutrophic lakes of the northern contiguous US. Climate warming is projected to eliminate winterkill in these lakes. This would be a positive effect of climate warming. Fish species under ice may still experience periods of stress and zero growth due to low DO conditions under projected climate warming.

Verificou-se que a dieta de B. iheringii nos quatro riachos consistiu de itens alimentares que variaram em número, e os de maior importância foram: restos vegetais e detrito, no Cambé; detrito, no Taquari; algas filamentosas e restos vegetais, no Água da Floresta; detrito e restos de insetos, no Baroré. O comportamento de mudar de estratégia, de generalista para especialista, e de utilizar o item detrito, que é capturado apenas no fundo, como principal alimento, podem ser indicadores que trechos de riachos com águas mais lentas e profundas não são preferenciais para B. iheringii, como também não são para alguns grupos de insetos aquáticos que servem como seu alimentoIndividuals of Bryconamericus iheringii (Boulenger, 1887, collected in the streams of Cambé, Taquari, Água da Floresta and Baroré, which belong to the Tibagi river basin (Parana Sate, Brazil, were analyzed for the purpose of diet study. The collection procedures were standardized in every stream. The stomach contents of the individuals were analyzed qualitative and quantitatively. The food items consumed by the species varied in number, and the main food item consumed differed in each stream. Thus, it was found: vegetable remains and debris, in Cambé; debris, in Taquari; filamentous algae and vegetable remains, in the Água da Floresta; and debris and remains of insects, in Baroré stream. The behavior shift from generalist to specialist strategy as well as the use of detritus as the main food, which can only be found in the river bottom, can indicate that stretches of streams with slower and deeper waters are not preferred

    Full Text Available Objective: To determine the seroprevalence of brucellosis among cattle in some local government areas (LGA of the northern part of Plateau State, Nigeria. Methods: Sera obtained from a total of 270 randomly selected cattle from different herds in the four selected LGAs were for Brucella antibodies using the Rose Bengal Plate Test (RBPT. Results: An overall brucellosis seroprevalence of 9.6% (26/270 was obtained. The seroprevalence of Brucella antibodies among the cattle across the LGA ranged from 0%-37.3% with Riyom and Bassa LGA having the lowest and highest seroprevalence respectively while Barkin Ladi LGA had no sero-positive cattle. Females had a higher percentage of seropositives compared to males while cattle reared under extensive system of management had a higher (11.6% percentage of sero-positives compared to cattle kept under the intensive system of management. However, there was no statistically significant (P>0.05 association between serological status and sex or management practice. Conclusions: The results of this study indicates that bovine brucellosis is still a problem among the cattle population in Plateau State, Nigeria. And the public and other animals are at risk of exposure to the disease agent in these animals which are still shedding the organism.

By confronting the serological status of the animals with variables of questionnaire, there was association (p < 0.01 between seropositivity of cows and the natural sources of drinking water, the incidence of abortion and repeating estrus. However, there was no statistical association between seropositive cows and the occurrence of neonatal deaths (p = 0.075, stillbirths (p = 0.02, presence of domestic dogs (p = 0.9 and the habit of giving raw offal to dogs (p = 0.93. Besides the occurrence of N. caninum, it was evidenced misinformation about bovine neosporosis and its control among interviewed people. This first study shows the need for further research on the epidemiology of bovine neosporosis in northern Mato Grosso state.

    1993-01-01

    In October of 1990, Northern States Power Company (NSP or Company), filed a unique open transmission tariff for both captive customers and through-system transactions. This is an important step towards expanding transmission services in the United States. Many individuals in the utility industry, who may be considering Imposing generation costs on transmission services, have been closely monitoring NSP's case which is currently before the Federal Energy Regulatory Commission (FERC). NSP's innovative generation costs include charges for reactive power production, frequency control, load dispatching, and load following. The results of this case may also have an important impact on the future of open transmission tariffs. Rates for these services depend on the customer's classification as either a captive or through-system consumer. The proposed tariff raises critical issues related to the costing of these transmission services. NSP's methodology has caused serious concern because the proposed tariff would increase transmission costs by an average of 53%. This paper will discuss the benefits of transmission, proposed rates, contract terms, and costing methodologies of NSP's plan

    Full Text Available The aim of the study was to determine the presence of antibodies against Neospora caninum and its DNA in blood samples from bovine females from the northern region of the state of Veracruz, Mexico. A cross-sectional epidemiological study was carried out in 13 municipalities, with a sample size of 821 animals. Blood and serum samples were analyzed through ELISA and PCR, respectively. Overall prevalence was 20.8 %; the highest specific prevalences were obtained in breeding cows (27.4 %, crossbred cows (20.9 %, second-calving cows (23.2 %, three year-old cows (20.6 % and cows with abortion history (20 %. The risk factors associated with seropositivity were dairy cattle (OR = 1.9; IC95 %: 1.1-3.4 and dog presence in the farms (OR = 5.3; IC95 %: 1.3-22.3. The presence of N. caninum DNA was demonstrated in 4 out of 12 blood samples tested, which evidenced the existence of active infection. In conclusion, there were risk factors associated with bovine neosporosis, which proved the existence of active infection by N. caninum in cows from the state of Veracruz, Mexico.

  14. Current state and prospects of carbon management in high latitudes of Northern Eurasia

    The current state and trajectories of future development of natural landscapes in high latitudes of Northern Eurasia are defined inter alia by (1) current unsatisfactory social and economic situation in boreal Northern Eurasia; (2) the dramatic magnitude of on-going and expected climatic change (warming up to 10-12oC under global warming at 4oC); (3) increasing anthropogenic pressure, particularly in regions of intensive oil and gas exploration and extraction; (4) large areas of sparsely populated and practically unmanaged land; (5) vulnerability of northern ecosystems which historically developed under cold climates and buffering capacity of which is not well known; (6) risk of catastrophic natural disturbances (fire, insect outbreaks) whose frequency and severity have accelerated during recent decades; and (7) high probability of irreversible changes of vegetation cover. These specifics are overlapped with insufficient governance of natural renewable resources (e.g., forests) and destructed practice of industrial development of new territories (oil and gas extraction and exploration, metallurgy etc.). Based on a full carbon account for terrestrial vegetation ecosystems of Northern Eurasia, we analyze the relative impacts of major drivers on magnitude and uncertainty of the Net Ecosystem Carbon Balance (NECB) under current and expected climate and environment. Dynamic trends and interannual variability of NECB are mostly dependent on weather conditions during growth seasons of individual years, regimes of natural disturbances, and anthropogenic impacts on ecosystems. In a short term, disturbances and human impacts cause a theoretically 'manageable' part of the full carbon account, which on average is estimated to be of about 20% of annual net primary production. In a long term, thawing of permafrost and change of hydrological regimes of vast territories may result in a catastrophic decline of the forested area and wide distribution of 'green desertification'.

    This paper aims to identify and to present mineralogical and chemical arguments that demonstrate the existence of bentonite levels in the Irati Formation, found in outcrops to the west Acegua in southern Rio Grande do Sul (Brazil). These levels are thin, on average 4 cm thick, large in area, and are composed of grayish-white to greenish massive clay stones that contrast, in the field, with the shales of the Irati Formation. The bentonite levels of the Irati Formation are predominantly composed of Ca-montmorillonite, which constitutes the fine matrix of the rock; and scattered primary or magmatic crystals not larger than very fine sand. Among the main primary minerals representative of volcanic setting, it is possible to identify β-quartz paramorphs, sanidine, biotite, zircon, apatite and ilmenite, in addition to quartz and feldspar shards (splinters). More rarely, fragments of meso and macrocharcoals are found within the bentonite layers, which contrast with the maturity and type of non-vegetal organic matter of the Irati shale. Therefore, the nature of the precursor volcanism is inferred on the basis of rock geochemistry and crystal chemistry of the neoformed montmorillonite in the bentonite levels. Both methodologies indicate that during this period the volcanic ashes that reached the Parana Basin were generated by volcanism of intermediate composition, which is in accordance with what is known about the Lower Choiyoi Volcanic Province manifestations, which were synchronous with the sedimentation of the Irati Formation in the Parana Basin.

  1. Using AMS to Help Interpret Glaciogenic Deposits of the Late Paleozoic Ice Age in the Parana Basin, Brazil

    Amato, James Anthony

    Basin, Brazil. 19 fabrics were analyzed from seven different locations (Alfredo Wagner, Aurora, Cachoeira do Sul, Campo do Tenente, Ibare, Porto Amazonas, and Sao Gabriel), stretching across the states of Rio Grande do Sul, Santa Catarina, and Parana. While in most cases, AMS allowed us to delineate between the origins of diamictites, in other cases, it proved to be more difficult. In most cases, AMS measurements were beneficial in determining the direction of sediment transport. Our findings are consistent with past studies in which AMS was used to infer a variety of glaciogenic deposits, but also acts as a study case for the different types of fabrics that may develop as a result of Newtonian vs non-Newtonian sediment gravity flows. While flow directions along the southern margin of the basin are consistent with the inferred N/NW ice movement into the basin, some of the flow directions along the eastern margin are not, revealing deviations in topography. Flow directions obtained from mass transport deposits in the area stretching from Campo do Tenente to Porto Amazonas (an area in which different stratigraphic levels of glaciation are exposed) tend to show uniform flow to the south. This observation is consistent with other AMS studies of similar deposits within the area, suggesting the existence of a southward paleoslope, which strongly influenced subaqueous deposition throughout the extent of the Itarare Group.

    Three review studies were conducted in response to the renewed interest in building a large diameter buried chilled natural gas pipeline in the Mackenzie Valley, Northwest Territories, to transport gas from the Beaufort/Mackenzie Delta to southern markets. The 3 review studies were commissioned by the Geological Survey of Canada to document the current state of knowledge about frost heave theory, testing and predictive modelling. The usefulness of this knowledge to the design, construction and operation of a buried chilled gas pipeline was also evaluated. The studies addressed one of the primary technical and engineering design issues that must be considered in the design of northern pipelines, that of the development of a frost bulb around buried chilled pipelines, and the associated heave of frost-susceptible soil and stresses imposed on the pipeline. The issue of differential heave is of particular concern. The information gathered from this study can be used to form the basis for the regulatory review process. This open file report provides a summary of the 3 studies. The 3 individual commissions reports were catalogued separately for inclusion in this database. refs., tabs., figs.

    Some reasons for the slow progress in low-grade heat utilization are examined. Economically, most schemes are, at best, only marginally attractive and problems of integration with the source of the low-grade heat are often formidable. The temperature, quality, variability and reliability of the warm water discharge is often less than ideal. A power utility or other producer of low-grade heat must be convinced that its utilization does not result in unacceptably lower efficiency or reliability of its process. Social or political factors are considered most likely to provide the incentive for making significant advances in low-grade heat utilization. Studies carried out in Canada and the Northern United States are reviewed and include aquaculture, open field soil warming, controlled greenhouses, spray irrigation for frost protection, ice control in waterways, organic waste treatment, residential heating, recreation and integrated systems. It is concluded that agricultural uses may have greatest potential for development in cold climates in North America. (author)

    Both sheep and goat pox are contagious viral diseases and affect small ruminants and are caused by sheep pox virus and goat pox virus respectively that belong to genus Capripoxvirus of Poxviridae family. Huge economic losses emanating from the disease outbreaks are the results of the wool and hide damage, subsequent production losses and also the morbidities and mortalities associated with the disease. This communication highlights clinico-epidemiological observations from the two sheep pox and one goat pox outbreaks. Grossly, multisystemic nodular lesions, mucopurulent nasal discharges and respiratory symptoms were observed in the affected animals. The morbidity, mortality and case fatality rates were 5.18%, 2.45% and 32.37%, respectively. Histopathological, haematological, molecular and serological techniques and also isolation of virus in embryonated chicken eggs were used for the diagnosis of the diseases. The spatial distribution of the disease signifies the role of common pasturelands used for grazing the animals while temporally all three outbreaks occurred in winters and were probably associated with cold stress and fodder scarcity. This is the first recorded report of Capripoxvirus infection in recent times and it highlights the disease as one of the emerging diseases in the northern state of Himachal Pradesh in India. © 2010 Blackwell Verlag GmbH.

    Full Text Available Pesticides are considered an important risk factor for human health and have been the subject of several studies, both for its toxicity and environmental degradation. This study aimed to diagnose the knowledge level of farmers from the Central Northern Paraná State on the safe pesticides use. For this we used a questionnaire that addressed issues related to intoxication, use of personal protective equipment (PPE and knowledge about inserts and labels. We interviewed 100 farmers affiliated to cooperatives in the region. After analyzing the responses, we observed that most farmers did an incomplete use of PPE in their daily activities, or did not use it, as it was found in all cases of poisoning. The terms used in the pesticides inserts and labels are not properly understood by farmers, contributing to increased problems in the safe handling of these products. The study concludes that it is necessary to have a process of training and guidance from regulators and the companies involved, as inputs companies, cooperatives and technical assistance agencies aiming more judicious use of the products and decreasing the risks to health of rural populations and environment.

    There is poor oral health awareness in Nigeria because of limited access to correct information on oral health as well as a lack of oral health-care providers. The purpose of this study was to describe the roles of community pharmacists (CPs) in Plateau State, Northern Nigeria, as sources of oral health information in their communities. A quantitative cross-sectional study on CPs spanning the entire State. Data collection was a survey method using a structured paper-based self-administered questionnaire. Analysis, which included t-tests and binary logistic regression, was carried out using SPSS ver. 23. A one-sample t-test to assess the attitudes of CPs on oral health showed that they had a very good disposition towards engaging in oral health services [advice, referrals, recommendations and basic treatment (e.g. of pain); mean  = 4.54, standard deviation  = 0.59, t(111) = 27.8, P oral health problems, 94.7% were willing to do more to advance the cause of oral health care. Training of CPs on oral health (32%), removal of restrictive policies in the health bill (1.8%) and sensitising the public (6.3%) were some suggestions on how to improve these services. The disposition of CPs towards improving oral health could serve as a platform to help propagate oral health care and awareness in their communities. Engaging the CPs might help to reduce oral health disparities by increasing oral health awareness and improving the quality of life via cost-effective delivery of pharmacy-based oral health-care services. © 2018 FDI World Dental Federation.

    The analysis of injuries of floating crew of the Northern water pool in a state of alcoholic intoxication havebeen based on the 180 accidents on board of ships with temporary loss of ability to work, and 1686 casehistories with alcoholic injuries, which demanded treatment in a surgical department. Among persons,the received injuries on the ship in the state of alcoholic intoxication were 8.1% of the victims: in thestrength of the transport fleet - 8.9%; fishing - 8.9% and river ones - 4.1%. Masters of fish production,skippers, rulers of the radio stations and masters of fish processing were most frequently injured afterthe consumption of the alcoholic beverages. Alcoholic injuries have been recorded at the time of walkingon the catwalk and the decks (54.2%), mooring operations (15.1%), maintenance and repairing the deckmachinery, water preparation (6.6%), as well as boat and loading-unloading works (4.3%). Falls from heightconstituted 36.6% of the injuries. Alcohol in 3.2 times increases the weight of the combined injuries. Thedeaths from the alcohol related injuries in marine conditions (43.4%) significantly exceed the indicators inthe group of non-alcoholic injuries (7.0%). Alcoholic intoxication has been noted in 35.0% of the cases ofthe floating crew injuries, hospitalised in the surgical department. Victims with alcoholic injuries receivedduring performing ship's works were hospitalised 10 times less, than those with non-productive types ofinjuries. In the structure of non-industrial injuries, household injuries prevail (78.2%) over those receiveddue to falls on the street, in pedestrian flows (10.3%), transport and traffic accidents (6.7%), intentionalinjuries (4.1%) or those connected with sports games and competitions (0.7%).

  11. Analysis of socioeconomic and environmental constraints to implement forestry in the Northern and Northwestern areas of Rio de Janeiro State

    Directory of Open Access Journals (Sweden)

    Rogério Silva Burla

    2013-01-01

    Full Text Available The Northern and Northwestern sections of Rio de Janeiro State have historically invested in coffee growing – an important crop in the agricultural and export history of Brazil, along with sugar cane plantations to meet the demands of the sugar industry which has, over the past decades, lost its dynamics. In this scenario, pastures have increased, making farming the major agricultural activity in these regions. However, this has been conducted with low technology and productivity, leading to environmental degradation. This paper proposes forestry as a sustainable development alternative for the Northern and Northwestern areas of the state. It was possible to verify that these regions have adequate socio-economic and environmental conditions for the installation of various forest species. If well managed, this activity can generate attractive economic initiatives, as well as environmental preservation and conservation.

    Full Text Available BACKGROUND Triatoma sordida and Triatoma pseudomaculata are frequently captured triatomine species in the Brazilian savannah and caatinga biomes, respectively, and in Brazilian domiciles. OBJECTIVES This study identified eco-epidemiological changes in Chagas disease in northern Minas Gerais state, Brazil, and considered the influence of environmental shifts and both natural and anthropogenic effects. METHODS Domicile infestation and Trypanosoma cruzi infection rates were obtained from triatomines and sylvatic reservoirs during the following two time periods: the 1980s and 2007/2008. Entomological and climatic data with land cover classification derived from satellite imagery were integrated into a geographic information system (GIS, which was applied for atmospheric correction, segmentation, image classification, and mapping and to analyse data obtained in the field. Climatic data were analysed and compared to land cover classifications. RESULTS A comparison of current data with data obtained in the 1980's showed that T. sordida colonised domiciliary areas in both periods, and that T. pseudomaculata did not colonise these areas. There was a tendency toward a reduction in T. cruzi infection rates in sylvatic reservoirs, and of triatomines captured in both households and in the sylvatic environment. T. sordida populations have reduced in the sylvatic environment, while T. pseudomaculata showed an expanding trend in the region compared to counts observed in the 1980's in the sylvatic environment. This may be related to high deforestation rates as well as gradual increases in land surface temperature (LST and temperatures along the years. MAIN CONCLUSIONS Our results suggest a geographical expansion of species into new biomes as a result of anthropogenic and climatic changes that directly interfere with the reproductive and infection processes of vectors.

  14. Different Stratospheric Polar Vortex States linked to Cold-Spells in North America and Northern Eurasia

    2017-12-01

    The stratospheric polar vortex in boreal winter can influence the tropospheric circulation and thereby surface weather in the mid-latitudes. Weak states of the vortex, e.g. associated with Sudden Stratospheric Warmings (SSWs), often precede a negative phase of the North Atlantic Oscillation (NAO), and thus increase the risk of mid-latitude cold-spells especially over Eurasia. Here we show using cluster analysis that next to the well-documented relationship between a zonally symmetric disturbed vortex and a negative NAO, there exists a zonally asymmetric pattern linked to a negative Western Pacific Oscillation (WPO) and cold-spells in the northeastern US, like for example observed in February 2014. The latter is more synoptic in time-scale but occurs more frequently than SSWs. A causal effect network (CEN) approach gives insights into the underlying physical pathways and time-lags showing that high-pressure around Greenland leads to vertical wave activity over eastern Siberia leading to downward propagating waves over Alaska and high pressure over the North Pacific. Moreover, composites propose that a rather strong mid-stratospheric vortex seems to be favorable for this zonally asymmetric and reflective mechanism. Overall, the mutual relationship between stratospheric circulation and high-latitude blocking in both the Pacific and Atlantic Oceans is complex and involves mechanisms operating at different time-scales. Our results suggest that the stratospheric influence on winter circulation should not exclusively be analyzed in terms of a downward propagating Northern Annular Mode (NAM) signal and SSWs. In particular when studying the stratospheric impacts on North American temperature it is crucial to also consider the more transient and zonally asymmetric events which might help to improve seasonal winter predictions for this region.

  16. The flora of Early Permian coal measures from the Parana Basin in Brazil: A review

    International Nuclear Information System (INIS)

    Iannuzzi, Roberto

    2010-01-01

    This paper presents an updated overview integrating both previous and newly published data on the most important floras found associated with Early Permian coal seams in the Parana Basin, Brazil. These floras occur within the Rio Bonito Formation and correspond to the Gondwana ''Glossopteris Flora.'' For this review, five floras are selected, in ascending stratigraphic order: the ''Sao Joao do Triunfo,'' ''Figueira,'' ''Quiteria,'' ''Morro do Papaleo'' and ''Irapua Bed'' floras. They are the best-known floras of the basin in terms of taxonomic composition, paleoecology and environments of deposition. An early-mid Sakmarian to earliest Artinskian age is indicated for the Rio Bonito Formation based on absolute radiometric and relative biostratigraphic ages. Integration of available information about the selected floras allows evaluation of taphonomic and paleoecological factors to provide a more comprehensive understanding of the Early Permian floral record in the Parana Basin. The variation observed in both the taxonomic composition of individual floras and in the frequency of occurrence of different plant groups is due to the broad range of environmental/edaphic conditions that prevailed in the many different depositional settings represented in the Rio Bonito Formation. A more precise age determination obtained for the plant-bearing deposits permits the establishment of a more confident correlation between the Early Permian floral succession in the Parana Basin and other Early Permian floral successions in other basins. The Sakmarian global warming favored the appearance of pecopterid and sphenopterid ferns amongst the spore-producing plants, and the glossopterids amongst the pollen-producing plants. (author)

    This paper presents an updated overview integrating both previous and newly published data on the most important floras found associated with Early Permian coal seams in the Parana Basin, Brazil. These floras occur within the Rio Bonito Formation and correspond to the Gondwana ''Glossopteris Flora.'' For this review, five floras are selected, in ascending stratigraphic order: the ''Sao Joao do Triunfo,'' ''Figueira,'' ''Quiteria,'' ''Morro do Papaleo'' and ''Irapua Bed'' floras. They are the best-known floras of the basin in terms of taxonomic composition, paleoecology and environments of deposition. An early-mid Sakmarian to earliest Artinskian age is indicated for the Rio Bonito Formation based on absolute radiometric and relative biostratigraphic ages. Integration of available information about the selected floras allows evaluation of taphonomic and paleoecological factors to provide a more comprehensive understanding of the Early Permian floral record in the Parana Basin. The variation observed in both the taxonomic composition of individual floras and in the frequency of occurrence of different plant groups is due to the broad range of environmental/edaphic conditions that prevailed in the many different depositional settings represented in the Rio Bonito Formation. A more precise age determination obtained for the plant-bearing deposits permits the establishment of a more confident correlation between the Early Permian floral succession in the Parana Basin and other Early Permian floral successions in other basins. The Sakmarian global warming favored the appearance of pecopterid and sphenopterid ferns amongst the spore-producing plants, and the glossopterids amongst the pollen-producing plants. (author)

    Full Text Available Chironomids, diatoms and microcrustaceans that inhabit aquatic ecosystems of the Northern Neotropics are abundant and diverse. Some species are highly sensitive to changes in water chemical composition and trophic state. This study was undertaken as a first step in developing transfer functions to infer past environmental conditions in the Northern lowland Neotropics. Bioindicator species abundances were related to multiple environmental variables to exploit their use as environmental and paleoenvironmental indicators. We collected and analyzed water and surface sediment samples from 63 waterbodies located along a broad trophic state gradient and steep gradients of altitude (~0-1 560m.a.s.l. and precipitation (~400-3 200mm/y, from NW Yucatán Peninsula (Mexico to southern Guatemala. We related 14 limnological variables to relative abundances of 282 diatom species, 66 chironomid morphospecies, 51 species of cladocerans, 29 non-marine ostracode species and six freshwater calanoid copepods. Multivariate statistics indicated that bicarbonate is the strongest driver of chironomid and copepod distribution. Trophic state is the second most important factor that determines chironomid distribution. Conductivity, which is related to the precipitation gradient and marine influence on the Yucatán Peninsula, is the main variable that shapes diatom, ostracode and cladoceran communities. Diatoms, chironomids and cladocerans displayed higher diversities (H=2.4-2.6 than ostracodes and copepods (H=0.7- 1.8. Species richness and diversity were greater at lower elevations (Los quironómidos, diatomeas y microcrustaceos que habitan ecosistemas acuáticos en el norte de los Neotrópicos son abundantes y diversos. Algunas especies son altamente sensibles a cambios en la composición química del agua y en el estado trófico.

    Exposure to certain pollutants induces a series of alterations in deoxyribonucleic acid (DNA) that may result in genotoxic/mutagenic effects in exposed individuals. The present study aimed to monitor genotoxic, mutagenic, and recombinogenic potential and consequently water quality in two streams in the Paranaíba River basin in the state of Minas Gerais, Brazil, using two bioindicator fish (Rhamdia quelen and Geophagus brasiliensis). The micronucleus (MN) test and somatic recombination and mutation test (SMART) were employed to assess DNA damage. The water quality index (WQI) at the reference site control (S1) due to its proximity to the river source was compared to Córrego do Óleo (S2) with respect to chemical parameter levels of biochemical oxygen demand (BOD), dissolved-oxygen rates (DO), and total solid and fecal coliform counts. These chemical parameters were above the permitted limits at Córrego do Óleo (S2). At a third site, Córrego Liso (S3), a poor WQI was detected, attributed to the influence of domestic and industrial activities where BOD, DO, total solid, fecal coliform, total phosphorus, and turbidity rates exceeded premissible limits. The MN frequencies and the numbers of MN per cell (CMN) at sites S2 and S3 were significantly higher than those at S1 in both species. It is of interest that the increased frequency of MN was similar to the positive control cyclophosphamide only at S3, suggesting that the effects of water contaminants were most severe at this site. At sites assessed (S2 and S3), there was a significant rise in somatic mutation and recombination in the wings of Drosophila melanogaster, indicating the presence of trace elements, mainly lead (Pb) and cadmium (Cd), in the effluents in the Paranaíba River basin sites.

    Document available in extended abstract form only. Full text of publication follows: The design of geological repositories for radioactive waste responds to the requirements of technical feasibility and long-term safety in the context of a specific geological setting. An important aspect of the geological setting is the primary stress field. To a large extent the stress state controls repository induced effects such as the excavation damage zone and the associated potential changes in the waste isolation properties of the host rock. Therefore the measurement of the stress state receives some attention where the site selection for geological repositories focuses onto relatively weak host rocks such as clay-stones and marly shales that tend to develop a significant excavation damage zone. Measurements of the minimum stress magnitudes in a recently drilled geothermal well in the Molasse Basin of northern Switzerland have yielded a stress profile reaching from 592 m to 1455 m depth. It straddles several rock units and includes the top of the crystalline basement. The sedimentary sequence consists of Marine limestones, shales and marls unconformably covered by Tertiary rocks of the Molasse. In other parts of the basin the evaporitic rocks of the Triassic Muschelkalk formation at the base of the sedimentary layer served as a regional detachment and enabled thin skinned thrusting and the formation of the Jura Fold and Thrust Belt in the Late Miocene. The stress measurements have been performed in the open hole by Mini-frac tests. The method uses a double packer system to isolate a one meter long interval of the borehole that is then pressurized at high injection rates up to the breakdown of the formation. Repeated pressurization of the interval allows to determine the stress that acts on the newly created fracture. The total injected volume during such a test is in the range of a few litres and the size of the fracture that extends from the borehole normal to the minimum

    The quality and safety of maize (Zea mays L.) from different grain storage units (GSUs), located in the main producing region of Rondônia State, Northern Brazil, were evaluated. Maize grains (n = 76) stored in four GSUs were collected from July to November 2014 and evaluated for grain damages, humidity, fungi and fumonisins (FBs) content. The climate conditions data were also obtained from plant growing to storage periods. Regarding the moisture content and water activity (a w ), these varied from 10.0% to 16.1% and 0.5 to 0.8, respectively. As expected, fungi spores were present in 94.8% of the samples, prevailing Fusarium genera, with a fungi colony maximum of 2.2 × 10 4 CFU g -1 . Regarding FBs, 60.5% of the samples were contaminated, below Brazilian and United States maximum limits, but 9.2% had levels higher than the European legislation.

    In areas with a seasonal snowpack, a warmer climate could cause less snowfall, a shallower snowpack, and a change in the timing of snowmelt, all which could reduce the winter albedo and yield an increase in net short-wave radiation. Trends in temperature, precipitation (total and as snow), days with precipitation and snow, and winter albedo were investigated over the 60-year period from 1951 to 2010 for 20 meteorological stations across the Northern Great Plains. This is an area where snow accumulation is shallow but persistent for most of the winter (November to March). The most consistent trends were minimum temperature and days with precipitation, both of which increased at a majority of the stations. Among the stations included, a decrease in the modelled winter albedo was more prevalent than an increase. There was substantial spatial variability in the climate trends. For most variables, the period of record used influenced the magnitude and sign of the significant trends.

    This paper reviews current abortion law and practice in Northern Ireland (NI). It explores the origins of NI's abortion law and its complexity in relation to current practice. It reviews issues relating to women seeking terminations in NI and Great Britain and reviews attempts by the Family Planning Association in NI to require the Department of Health, Social Services and Public Safety NI to clarify the current legal basis for termination of pregnancy and to provide guidance for health professionals engaged in this practice. The paper also discusses some of the issues surrounding abortion in NI and seeks to explain why this subject is causing controversy and debate, especially following a judicial review in February and Marie Stopes opening a termination service in Belfast.

    Population fragmentation compromises population viability, reduces a species ability to respond to climate change, and ultimately may reduce biodiversity. We studied the current state and potential causes of fragmentation in grizzly bears over approximately 1,000,000 km 2 of western Canada, the northern United States (US), and southeast Alaska. We compiled much of our data from projects undertaken with a variety of research objectives including population estimation and trend, landscape fragmentation, habitat selection, vital rates, and response to human development. Our primary analytical techniques stemmed from genetic analysis of 3,134 bears, supplemented with radiotelemetry data from 792 bears. We used 15 locus microsatellite data coupled withmeasures of genetic distance, isolation-by-distance (IBD) analysis, analysis of covariance (ANCOVA), linear multiple regression, multi-factorial correspondence analysis (to identify population divisions or fractures with no a priori assumption of group membership), and population-assignment methods to detect individual migrants between immediately adjacent areas. These data corroborated observations of inter-area movements from our telemetry database. In northern areas, we found a spatial genetic pattern of IBD, although there was evidence of natural fragmentation from the rugged heavily glaciated coast mountains of British Columbia (BC) and the Yukon. These results contrasted with the spatial pattern of fragmentation in more southern parts of their distribution. Near the Canada-US border area, we found extensive fragmentation that corresponded to settled mountain valleys andmajor highways. Genetic distances across developed valleys were elevated relative to those across undeveloped valleys in central and northern BC. In disturbed areas, most inter-area movements detected were made by male bears, with few female migrants identified. North-south movements within mountain ranges (Mts) and across BC Highway 3 were more common

    Miguel J Villasuso-Pino

    2011-04-01

    Full Text Available The coastal zone of northern Yucatan Peninsula (YP is mainly constituted by Tertiary limestones, covered by Pleistocen limestones, where there exist swamps and estuary systems, locally called “rías”, with mouths connecting them to the sea and hence being a way for an important amount of groundwater to discharge, like in Ría Lagartos and Celestún. These limestones have karstic layers located at depths from 8 to 16 meters below terrain surface.  It is in these layers where groundwater mainly flows toward coast, passing below the sand dune and discharging in the sea in the form of submarine springs which in many cases manifest themselves on the marine surface depending on the hydraulic or piezometric fresh water head. The width of the superficial limestone within this coastal fringe, called “caliche”, varies from 5 to 10 kilometers in the study zone (Chuburna-Progreso-Chicxulub.  Its permeability is extremely low, so it constitutes a confining layer that impedes superficial waters to percolate toward groundwater.  The hydraulic head of the groundwater below this confining layer is over the mean sea level and also over the swamp water level, coastal lagoons and estuaries. There are two important hydrological phenomena that occur in this coastal fringe: 1 There is no recharge to the aquifer (groundwater due to limestone rock outcrops is impermeable or semipermeable; and 2 groundwater pressure is not lost, nor saline interfase is rised if the superficial layer is broken.  The groundwater pollution vulnerability within this coastal fringe is less than that for the superficial saline waters of swamps and estuaries, because of caliche’s low intrinsic permeability that impedes percolation.

    Parrots are largely considered plant antagonists as they usually destroy the seeds they feed on. However, there is evidence that parrots may also act as seed dispersers. We evaluated the dual role of parrots as predators and dispersers of the Critically Endangered Parana pine (Araucaria angustifolia). Eight of nine parrot species predated seeds from 48% of 526 Parana pines surveyed. Observations of the commonest parrot indicated that 22.5% of the picked seeds were dispersed by carrying them in their beaks. Another five parrot species dispersed seeds, at an estimated average distance of c. 250 m. Dispersal distances did not differ from those observed in jays, considered the main avian dispersers. Contrary to jays, parrots often dropped partially eaten seeds. Most of these seeds were handled by parrots, and the proportion of partially eaten seeds that germinated was higher than that of undamaged seeds. This may be explained by a predator satiation effect, suggesting that the large seeds of the Parana pine evolved to attract consumers for dispersal. This represents a thus far overlooked key plant-parrot mutualism, in which both components are threatened with extinction. The interaction is becoming locally extinct long before the global extinction of the species involved.

Samplings were collected in summer (April and winter (September, 2002, in upper, intermediary and lower regions. A total of 66 cyanobacterial species were registered, with fifty species occurring in Iraí Reservoir and thirty-eight in Segredo Reservoir. Iraí showed higher values of cyanobacteria density (25 to 101 x ind 103 cm-2 when compared with Segredo (1 to 14 x ind 103 cm-2. We believe that cyanobacteria composition and density resulted from several factors, with preponderance of the effects of abiotic variables differences (nitrogen, phosphorus and temperature along the longitudinal axis and along the different seasons, as well as the morphometric and hydrodynamic effects.

    Unknown mixing state is one of the major sources of uncertainty in estimating aerosol direct radiative forcing (DRF). Aerosol DRF in India is usually reported for external mixing and any deviation from this would lead to high bias and error. Limited information on aerosol composition hinders in resolving this issue in India. Here we use two years of aerosol chemical composition data measured at megacity Delhi to examine the most probable aerosol mixing state by comparing the simulated clear-sky downward surface flux with the measured flux. We consider external, internal, and four combinations of core-shell (black carbon, BC over dust; water-soluble, WS over dust; WS over water-insoluble, WINS and BC over WINS) mixing. Our analysis reveals that choice of external mixing (usually considered in satellite retrievals and climate models) seems reasonable in Delhi only in the pre-monsoon (Mar-Jun) season. During the winter (Dec-Feb) and monsoon (Jul-Sep) seasons, 'WS coating over dust' externally mixed with BC and WINS appears to be the most probable mixing state; while 'WS coating over WINS' externally mixed with BC and dust seems to be the most probable mixing state in the post-monsoon (Oct-Nov) season. Mean seasonal TOA (surface) aerosol DRF for the most probable mixing states are 4.4 ± 3.9 (- 25.9 ± 3.9), - 16.3 ± 5.7 (- 42.4 ± 10.5), 13.6 ± 11.4 (- 76.6 ± 16.6) and - 5.4 ± 7.7 (- 80.0 ± 7.2) W m- 2 respectively in the pre-monsoon, monsoon, post-monsoon and winter seasons. Our results highlight the importance of realistic mixing state treatment in estimating aerosol DRF to aid in policy making to combat climate change.

    Detailed mapping at the NW corner of the large Neo proterozoic Cunhaporanga Granitic Complex (CGC), Parana state, SE Brazil, redefined the Joaquim Murtinho Granite (JMG), a late intrusion in CGC with an exposed area of about 10 km{sup 2}, made up mainly by evolved 'alaskites' (alkali-feldspar leuco granites). This unit is in tectonic contact with the Neoproterozoic-Eocambrian volcano-sedimentary Castro Group, to the W, and is intrusive into other less evolved granitic units of the CGC to the E. Petrographically, JMG shows mainly mesoperthite and quartz, with subordinate amounts of altered micas and some accessory phases, mainly zircon. The equi to inequigranular granites are usually deformed with cataclastic textures, are often brecciated, and may have miarolitic structures. Formation of late albite, sericite, carbonate and hematite was caused by deuteric and hydrothermal alteration. A gamma-ray spectrometric survey at 231 stations which measured total counts (TC), Ueq K%, eU ppm and eTh ppm was used to construct several direct and derived maps. Compared to neighboring units the JMG has significant anomalies, especially in the TC, %K, eTh and eU maps, although the differences are less obvious in some derived maps. These evolved granites are enriched in these three elements. Geochemical behavior of K, Th and U is used to analyse the results observed in maps. Enhanced weathering under a subtropical climate with moderate to high average temperatures and heavy rainfall affects mainly feldspars and biotite, and may also destabilize most U and Th-bearing accessory phases. Th is most likely retained in restite minerals in soils, being relatively immobile, while part of U may migrate as uranyl ion in oxidizing media. K is especially affected by feldspar alteration to K-free clays (mainly kaolinite), and may be completely leached. Gamma-ray spectrometric methods are valid tools to study facies in granitic rocks, especially in those that are enriched in K, Th and U

    To investigate the probable mixing state of aerosols in the Indo-Gangetic Basin, six different mixing cases, viz. external mixing, internal mixing, and four combinations of core-shell type mixing (black carbon, BC over dust, water-soluble over dust, BC over water-soluble and water-soluble over BC) have been considered. Composite single scattering albedo (SSA) have been computed for six cases for post-monsoon, winter and pre-monsoon seasons and are compared with the Aerosol Robotic Network (AERONET) retrieved SSA values. The most probable mixing state in the post-monsoon season seems either to be external mixing or water-soluble coating over dust and in the winter season, the external mixing seems to be the probable mixing state. However, in the pre-monsoon season, BC coating over dust seems to be the most probable mixing state. This type of mixing leads to enhanced absorption and needs future attention to better understand the aerosol radiative effect in this region.

    Full Text Available Research on fishing activity at Atafona village, in Northern Rio de Janeiro, Brazil (21°35'S, was carried out between 1987-96 for the purpose of relating it to the accidental capture of small cetaceans and of estimating the relationship between fishing activity and the diet of small cetaceans. Data on fishing operations were obtained at the cold storage plants management, from interviews with fishermen and personal observations. The most representative fishing resources were Xyphopenaeus kroyeri, Micropogonias furnieri, Carcharhinus plumbeus, C. acronotus,and Rhizoprionodon porosus. Gillnets are responsible for the accidental capture of small cetaceans in the region, mainly Pontoporia blainvillei and Sotalia fluviatilis (marine form. Four types of gillnets that are used on the region ("minjuada", "sarda", "caçoá" and "pescadinha" were dangerous to these species because they are placed in their preferred habitat.

    Full Text Available This paper presents the results of the planform stability classification for the headland-bay beaches of the State of Santa Catarina and of the Northern Coast of São Paulo, based on the application of the Parabolic Bay-Shape Equation (PBSE to aerial images of the beaches, using the software MEPBAY®. For this purpose, georeferenced mosaics of the QuickBird2® satellite imagery (for the State of Santa Catarina and vertical aerial photographs (for the northern coast of São Paulo State were used. Headland-bay beach planform stability can be classified as: (1 in static equilibrium, (2 in dynamic equilibrium, (3 unstable or (4 in a state of natural beach reshaping. Static equilibrium beaches are the most frequent along the coast of the State of Santa Catarina and the Northern Shore of São Paulo, notably along the most rugged sectors of the coast and those with experiencing lower fluvial discharge. By comparison, dynamic equilibrium beaches occur primarily on the less rugged sectors of the coast and along regions with higher fluvial discharge. Beaches in a state of natural beach reshaping have only been found in SC, associated with stabilized estuarine inlets or port breakwaters. However, it is not possible to classify any of these beaches as unstable because only one set of images was used. No clear relation was observed between a beach's planform stability and other classification factors, such as morphodynamics or orientation.Este trabalho apresenta resultados da classificação da estabilidade da forma em planta das praias de enseada do Estado de Santa Catarina e do Litoral Norte de São Paulo, realizada através da aplicação do modelo parabólico a imagens aéreas utilizando o software MEPBAY®.

    Full Text Available During the period of 1950 through 2000, a green-revolution-based model mostly for commodities boosted global agricultural production. From the 70’s, this design became consolidated in Brazil and other countries because of policies and strategies by states and private groups. However, some doubts has been raised on its environmental and socioeconomic issues, in special for family farming. This study aimed to contribute by identifying changes and resistance in agricultural structures, systems and demographic aspects of this model and its adoption by farmers. It was carried out in the state of Paraná - Brazil, within the microregion of Toledo and in the northern pioneer area, which represent the history and diversity of this state about socioeconomic and human aspects, as well as technical development. It was based on statistics of agricultural censuses (1970, 1975, 1980, 1985, 1996 and 2006, population censuses (1970, 1980, 1991, 2000 and 2010 and municipal agricultural production data (1980-2012. Data from both areas were compared to each other and analyzed in face of state changes. There has been a decrease in farming properties and rural population, with an outstanding decline in the number of young people and women. Moreover, results showed a large reduction of properties with 20 to 50 ha, and an increase in those of up to 2 ha. Such decline is due to technological standard changes throughout the period, as well as recent grants offered to rural areas, as housing and leisure spaces. Both regions showed expansion of soybean plantations, but integrating distinctively to agriculture and, finally, family farming continuity, despite the intense changes.

    2008-02-01

    The objective of this work is to study natural radionuclides in sedimentary rocks. The concentration of them reflects the origin of the sediments, the depositional environment as well as some mineralogical characteristics of the rock matrix, and also more recent events as weathering and erosion. Using gamma ray high resolution spectrometry, the profile of activity concentration of the natural radionuclides was assessed for 226 Ra, 238 U, 32 Th and 40 K in rocks of the Irati Formation belonging to Parana Sedimentary Basin. The samples were collected at a limestone abandoned mine, in the city of Sapopema, (PR). 24 samples were collected, eleven from the exposed vertical profile with approximately 5.50 m, whose stratigraphy is represented by an alternation among decimetrics layers of limestones, bituminous shales, and some rhythmits layers (milimetric sheets of limestone and bituminous shales), 9 repetitions of a sample to study the variability, and three rigolits samples in sequential apprenticeships of weathering. Each sample was dried in the sun during about 48 hours, broken, drizzled in a sieve of 4 mesh and put, in a cylindrical container. The measures were accomplished using a Germanium Hyper Pure detector (HPGe) with relative efficiency of 66%, connected to a standard spectrometry electronic chain. The measured concentrations of activity of 238 U were smaller for the limestones (17.80 ±0.09 Bq.Kg -1 ), larger for the bituminous shales (125.5 ± 2.6 Bq.Kg -1 with enrichment of uranium in the sample (200), 548 ± 16 Bq.Kg -1 , upper part of the column), and intermediate for the rhythmits (23.0 ± 1,3 Bq.Kg -1 . The ratio eTh/K obtained for the studied profiles has equivalent values, indicating similar mineralogical characteristics for the limestones, bituminous shales, rhythmits and studied rigolits. On the other hand, to the ratio eTh/eU showed that two of the three regolits samples belong to oxidizer atmospheres, favoring the leaching of uranium, what can be

    Exergy analysis is a powerful tool to evaluate, design and improve the thermal systems. The method of exergy analysis or availability analysis is well suited for furthering the goal of increasing the efficiency of existing power generation systems, and the capability of more effective energy resource use. Exergy analysis of the FIGUEIRA thermal power plant is presented. Exergy losses occurring in various components are considered and the exergy balance is shown in tabular form. Results clearly reveal that the steam generator is the principal site of thermodynamic losses, while the condenser is relatively unimportant. (author)

  11. Measurement of radioactive lines in powdered milk samples in Londrina (Parana State, Brazil) region

    Melquiades, Fabio Luiz

    2000-01-01

    This work deals with the measurement of radioactive lines in powdered milk, with high resolution gamma spectrometry, using a HPGe detector with relative efficiency of 10%, coupled to the electronic nuclear chain and a multichannel card of 8192 channels. Some tests were realized before beginning the measurements. The first of them was to define the shield to be used, making several measured with different shields according to the available materials, opting finally for a shield composed of bricks of lead (10 cm thickness), plates of iron (4nm thickness) and of aluminum (2 mm thickness). Four different geometries for the samples recipients were tested, and the Marinelli beaker of 2,1 liters totally filled was the one which supplied the best peak/background ratio. A statistical inference was also realized to determine the sampling that represents each one of the lots of milk to be measured, resulting in a number of 6 samples, for a confidence level of 95%. Two different kinds of powdered milk produced at Londrina were analyzed, Integral Powdered Milk Cativa and Integral Powdered Milk Polly. The samples were properly put in the Marinelli beaker of 2,1 L, sealed and kept for 40 days to reach the secular equilibrium. The counting time for each measurement was two days. It was possible to identify the radionuclides 40 K, 137 Cs and 232 Th (from 208 Tl), whose activities were calculated according to the International Atomic Energy Agency norms (IAEA, 1989). The detector efficiency was measured using calibrated samples, prepared with the certified reference materials IAEA-326 and IAEA-375. Corrections for self-absorption were accomplished, based on measures of samples with different densities. The results obtained for the powdered milk Cativa were: 464± 12 Bq/kg for 40 K, 3,46 ± 1,05 and 0,46 ± 1,05 and 0,46 ± 0,16 Bq/kg for the minimum detectable activities of 137 Cs and 232 Th, respectively. For the milk Polly, the results were: 452±10 Bq/kg for 40 K, 3,19 ± 0,63 and 0,32 ± 0,12 Bq/kg for the minimum detectable activities of 137 Cs and 232 Th, respectively. The statistical analyses performed checked the measurements repeatability by means of the Tukey's average comparison test. A correlation analysis between standard deviations and the mean showed the absence of significant systematic deviation. Comparison the results obtained with literature, it was demonstrated that the values of the activities found are within the normal levels of radioactivity for this kind of product and below the maximum permissible levels established by CNEN, that is, the analyzed milk can be normally consumed. On the other hand, the implemented methodology present a good performance, faced to the available experimental conditions. (author)

    Full Text Available Bovine Herpesvirus 4 (BoHV-4 is a member of Gammaherpesvirinaesub-family and belongs to genus Rhadinovirus. This virus has been associated with different clinical manifestations and research activity has put forward a strong correlation among virus infection, postpartum metritis, and abortion. The goal of this work was to characterize a virus strain isolate from a cow’s uterine outflow. From swabs drawn of uterine secretion, a virus strain was isolated and characterized by its cytopathology, morphology, and molecular biology approaches. In culture there was CPE development, characterized mainly by long strands with several small balloons along them, radiated from infected cells. Electron microscopy analysis revealed virus particles that had icosahedrical capsid symmetry surrounded by a loose envelope, typical of a herpesvirus. A 2,571 bp PCR product after HindIII digestion generated four fragments, whose base pair composition were 403, 420, 535, and 1,125 bp. Restriction enzymes HindIII and BamHI generated the expected diagnostic bands as well as a 2,350 bp hypermolar fragment as a result of BamHI treatment to demonstrate that agent was a bovine herpesvirus 4, appertaining to DN-599 group.

    The Self-organizing map (SOM) technique is used to estimate missing hydrogeologic (hydraulic and hydrochemical) properties and evaluate potential connectivity between the Serra Geral and Guarani aquifer system. K-means clustering of SOM neurons is useful for identifying hydrogeologic units (conceptual models) in which the Serra Geral waters are carbonate-calcium and carbonate-magnesium, and Guarani waters are sodium, chloride, fluoride and sulfate as characteristic elements. SOM predictions appear generally consistent with current connectivity models with vertical fluxes from Guarani aquifer strongly influenced by geological structures. Additionally, we identify other new hydrochemical facies in the Serra Geral aquifer indicating areas with potential connections between the two aquifers.

    Triatomine infestation, prevalence of T. cruzi antibodies in humans and domestic animals, and variables potentially associated with the presence of triatomines in a rural domiciliary unit (DU) were investigated in nine municipalities and one district of Parana, Brazil, from June 1996 to February 2000. DUs were defined as all houses and annexes on a given piece of property. Blood samples from human volunteers, dogs, and cats were submitted to indirect immunofluorescence. An epidemiological form was completed for each DU. A logistic model was adopted in order to identify associations. Seven out of nine municipalities were positive for triatomines. T. infestans was not captured, but T. sordida, P. megistus, and R. neglectus were. Different variables were considered decisive for the presence of triatomines across the municipalities: proximity to residual wooded areas, i.e. either scrub forest (capoeira) or islands of residual forest (slightly dense vegetation), longer time of residence, existence of inhabited houses, and past DU infestation. In order to ensure proper continuation of the recommended Chagas disease control program, entomo-epidemiological surveillance measures need to be maintained.

    Radioisotopic techniques used in the study of water perconlation at the exact place of the construction of the canal lock of Ilha Solteira Dam, in its left side is presented. At the time of the drilling operations, it was discovered, by water leakage tests, total lost at 275,00 level. This water lost occurred at the vicinities of basalt lava-flows. The water leakage tests showed that the total absorption of pumping flow was about 80 liters per minute. To determine the velocity of water percolation in the probable cracks or fractures of the basalt a test of radioactive tracer 131 I was used. For the study of the radioactive tracer behaviour two techniques were tried: measurement of its dilution in the original of the well and the measurement of residence time. Results from the tests showed the existence of a crack or a set of cracks oriented from the radcoisotopic injection well to the artesian wells located at the left shore of Parana river, below Ilha Solteira Dam. The mentioned cracks are localized at the 272,00 level, close tr the contact between the basalt lava-flows

  16. Genetic variability of populations of Nyssomyia neivai in the Northern State of Paraná, Brazil

    Directory of Open Access Journals (Sweden)

    Jaqueline de Carvalho Gasparotto

    Full Text Available ABSTRACT The genetic study of sandfly populations needs to be further explored given the importance of these insects for public health. Were sequenced the NDH4 mitochondrial gene from populations of Nyssomyia neivai from Doutor Camargo, Lobato, Japira, and Porto Rico, municipalities in the State of Paraná, Brazil, to understand the genetic structure and gene flow. Eighty specimens of Ny. Neivai were sequenced, 20 from each municipality, and 269 base pairs were obtained. A total of 27 haplotypes and 28 polymorphic sites were found, along with a haplotypic diversity of 0.80696 and a nucleotide diversity of 0.00567. Haplotype H5, with 33 specimens, was the most common among the four populations. Only haplotypes H5 and H7 were present in all four populations. The population from Doutor Camargo showed the highest genetic diversity, and only this population shared haplotypes with those from the other municipalities. The highest number of haplotypes was sheared with Lobato which also had the highest number of unique haplotypes. This probably occurred because of constant anthropic changes that happened in the environment during the first half of the twentieth century, mainly after 1998. There was no significant correlation between genetic and geographical distances regarding these populations. However, the highest genetic and geographical distances, and the lowest gene flow were observed between Japira and Porto Rico. Geographical distance is a possible barrier between these municipalities through the blocking of haplotype sharing.

    We describe two new species of Anomaloglossus from Roraima State, Brazil, that are likely endemic to single mountains currently isolated among lowland forest and savanna ecosystems. The first species, Anomaloglossus tepequem sp. nov. was collected in 1986 and 1992 along a single stream at >500 m elevation on a tepui-like mountain named Tepequém, but was not detected during recent investigations. It is mainly diagnosed from other Anomaloglossus species by its well developed foot webbing, immaculate cream abdomen colouration and small body size (males: 18.2-20.1 mm, females: 21.7-24.5). The second species, Anomaloglossus apiau sp. nov. was found along several streams between 500 and 1400 m elevation on Serra do Apiaú, and is mainly diagnosed from congeners by its weakly webbed feet, males with swollen third finger and ventrolateral stripe formed by white dots, and its advertisement call; a long trill (up to almost 40 s) consisting of pairs of very short pulses. The discovery of these two apparently microendemic species suggests that additional Anomaloglossus species remain to be described in the Guiana Shield. Both species should be considered critically endangered given their seemingly reduced range size, association with highland habitat, and the anthropogenic pressure they currently face.

    In this study blood samples were collected from 665 female from Northern State of Sudan, 606 of those females are married and only 59 females are singles. These samples were used to estimate the normal CA 15-3 which was found to be similar to the international one and that is ranged from zero to 35 mlu/ml. When the same techniques were used using samples collected from patients who have been clinically diagnosed as breast cancer, CA 15-3 levels were found to be higher in most of these samples and the other finding is that the risk of getting breast cancer is starting from age 25 years. On the other hand , 650 males were participated in this study to estimate normal value of PSA, of them 553 were married. And again the levels estimated for this marker was found to be the same as that used globally which is ranged from zero to four ng/ml. When blood samples from prostate patients were assayed for PSA, the results showed high levels of this marker in almost all the samples as expected but the important finding is that prostate cancer is age depend. At the end of the project, many recommendations highlighted to be considered in the near future.(Author)

    Libyostrongylus genus contains three species of gastrointestinal nematodes that infect ostriches. Of these, only Libyostrongylus douglassii has been implicated in diseases and lower productivity. A morphological diagnosis method allowing the discrimination of infective larvae of L. douglassii and Libyostrongylus dentatus and the evaluation of eggs per gram of feces (EPG) was used to determine the population dynamics of both species from two ostrich farms located in the northern region of the state of Rio de Janeiro, Brazil. The presence of these nematodes was monitored every 15 days for two years. The average EPG was 4631 and 587 on farms 1 and 2, respectively. Overall, the highest values of EPG were associated with the rainy season on both farms. However, only on farm 1 the rainy season correlated statistically with EPG. Both species of Libyostrongylus occurred on both farms with a higher predominance (86%) of L. douglassii on farm 1, whereas the distribution of infection on farm 2 was more heterogeneous with a slight predominance of L. douglassii. The infection and the prevalence of these species may vary considerably according to the farm facilities, management adopted, and season. Copyright © 2013 Elsevier B.V. All rights reserved.

    The northern Great Plains (NGP) of the United States has been a hotspot of West Nile virus (WNV) incidence since 2002. Mosquito ecology and the transmission of vector-borne disease are influenced by multiple environmental factors, and climatic variability is an important driver of inter-annual variation in WNV transmission risk. This study applied multiple environmental predictors including land surface temperature (LST), the normalized difference vegetation index (NDVI) and actual evapotranspiration (ETa) derived from Moderate-Resolution Imaging Spectroradiometer (MODIS) products to establish prediction models for WNV risk in the NGP. These environmental metrics are sensitive to seasonal and inter-annual fluctuations in temperature and precipitation, and are hypothesized to influence mosquito population dynamics and WNV transmission. Non-linear generalized additive models (GAMs) were used to evaluate the influences of deviations of cumulative LST, NDVI, and ETa on inter-annual variations of WNV incidence from 2004-2010. The models were sensitive to the timing of spring green up (measured with NDVI), temperature variability in early spring and summer (measured with LST), and moisture availability from late spring through early summer (measured with ETa), highlighting seasonal changes in the influences of climatic fluctuations on WNV transmission. Predictions based on these variables indicated a low WNV risk across the NGP in 2011, which is concordant with the low case reports in this year. Environmental monitoring using remote-sensed data can contribute to surveillance of WNV risk and prediction of future WNV outbreaks in space and time.

    Morphologic analyses of characteristic bedrock erosion forms found in northern New York State, USA were used to reconstruct the subglacial conditions under which they may have been produced. Observations from sites on Wellesley Island, N.Y, at Point Salubrious, N.Y, and at an open pit mine near Balmat, N.Y, were combined with regional mapping of a diverse suite of glacial erosion forms in order to establish the areal extent and significance of subglacial drainage in northern New York. Results of these site-specific and regional studies are the basis for discussion of the probable role of subglacial meltwater in the region. Bedrock erosion forms preserved at various locations in northern New York are interpreted as products of flow separation of localized subglacial meltwater during ice/bed decoupling. The regional distribution of these forms indicates that they are largely restricted to pre-existing subglacially-modified bedrock valleys that served as subglacial tunnel channels. Regionally extensive, deep, subglacial meltwater flow, characterized as sheetfloods, is not required to account for the erosional features described from specific sites in northern New York State.

    The flood plain of the upper Parana River is located among the lakes formed by the Brazilian hydroelectric plants being the last part of the Parana river, in Brazil, where there is an ecosystem with interaction river-flood plain. This flood plain has considerable habitat variability, with great diversity of terrestrial and aquatic species, and the floods are the main factor that regulates the operation of this ecosystem. The seasonality of the flood pulses is mainly influenced by the El Nino phenomenon, which increases precipitation in the drainage basin of the flood plain of the upper Parana River. Because of its unique characteristics this ecosystem is the subject of intense study since 1980, mainly from the ecological point of view. Therefore, two sediment cores were collected in the ponds formed by the floods, Patos pond and Garcas pond, in order to characterize the sediment chemically and evaluate a possible historic contamination. The trace element concentrations As, Ba, Br, Ce, Co, Cr, Cs, Eu, Hf, La, Lu, Nd, Rb, Sb, Sc, Sm, Ta, Tb, Th, U, Yb and Zn (mg.kg{sup -1}) and the major elements Si, Al, Fe, Ti, K, Ca, Mg, P, V, Mn, and Na (%) were determined in the sediment cores dated by {sup 210}Pb method, using instrumental neutron activation analysis, X-ray fluorescence and gross beta counting, respectively. The results obtained for the elements Ce, Cr, Cs, La, Nd, Sc, Sm and Th are higher than the values of Upper Continental Crust for both ponds. The sedimentation rates obtained for Garca pond, 0.77 cm.y{sup -1}, and Patos pond, 0.62 cm.y{sup -1} are in agreement with studies performed in sedimentary environments similar to the present work, such as Brazilian wetland Pantanal. The enrichment factor and the geo-accumulation index were used to assess the presence of anthropogenic sources of pollution. Document available in abstract form only. (authors)

    This study presents the results of Rn-222 and Rn-220 measurements in soil gas at the city of Curitiba, Metropolitan Area and Parana Coastal Region developed by the Laboratory of Applied Nuclear Physics of Federal University of Technology, Parana (UTFPR). The survey was performed using the AlphaGUARD instant radon detector (SAPHYMO) associated with gas probe, filter vessels and air pump (AlphaPUMP) following the recommendation of User Manual for soil gas measurements and practice protocols developed by CDTN. Each test consisted of three main steps: background evaluation, total activity measurement of Rn-222 and Rn-220 isotopes in soil gas and static activity measurements (with disconnected AlphaPUMP) of soil gas accumulated within the cavity of AlphaGUARD ionization chamber. Specific activity levels of Rn-222 and Rn-220 were obtained by theoretical decay curves fitting to the set of experimental data using scientific graphing and data analysis software Origin 6.1. Obtained Rn-222 concentrations in soil gas varied from 26.0 ± 8.2 kBq/m³ to 38.7 ± 7.7 kBq/m³ and the average values of Rn-220 were found in a range of 18.8 ± 7.4 kBq/m³ and 142±67 kBq/m³. It has to be noted that found activity of Rn-222 isotope in soil gas of studied locations of Parana is below 50 kBq/m³, which is the maximum radon activity level established by some European countries for classification of high-risk soil. Despite the high levels of Rn-220 activity in soil gas, this does not represent the health risk for the population since the half-life of Rn-220 is short (54.5 seconds). (author)

    In the southernmost part of the Parana Basin, records of the late Paleozoic glaciation occur in a discontinuous form preserved in paleovalley systems excavated in the crystalline basement. This paper addresses one of these paleovalleys, the Mariana Pimentel, which extends over 60 km with NW-SE valley direction and a constant width of 2.5 km. With the objective of demonstrating that the paleovalley worked as a fjord during the glaciation period, its origin as well as sedimentary fill and morphology were analyzed. The paleovalley morphology was obtained through electrical resistivity (electrical sounding and lateral mapping) and mathematical modeling in four transverse sections. The morphology of the paleovalley documented by the U-shape, steady width, and high depth reaching up to 400 m are typical features of modern glacial valleys. The sedimentary facies that fill the base of the paleovalley, such as rhythmites and dropstones with thickness up to 70 m and diamictites with faceted pebbles (up to 5 m thick) are signs of its glacial origin. During the glaciation period, the paleovalley had a connection to the epicontinental sea located to the northwest, extended toward Namibia, and was excavated by glaciers from the highlands of this region. Thus, the evidence attests that the Mariana Pimentel paleovalley was a fjord during the late Paleozoic glaciation. The duration of the late Paleozoic glaciation (which is longer than the Quaternary glaciation), the apatite fission track that suggests erosion up to 4 km thick in the study area, and the lack of preserved hanging valleys in the Mariana Pimentel indicate that the paleovalley once featured a higher dimension. Furthermore, the existence of paleofjords excavated in the border of the basement corroborates the idea of small ice centers controlled by topography during the late Paleozoic glaciation.

  10. The Parana paradox: can a model explain the decadal impacts of climate variability and land-cover change?

    2013-12-01

    Since the 1970s, despite a decrease in rainfall, flow in the Parana river has increased. This paradox is explored using the Ecosystem Demography (ED) model. If there were no change in land cover, the modeled runoff decreased from the 1970s to the 2000s by 11.8% (with 1970 land cover) or 18.8% (with 2008 land cover). When the model is run holding climate constant, the decadal average of the modeled runoff increased by 24.4% (with the 1970s climate) or by 33.6% (with 2000s climate). When the model is run allowing both the actual climate and land-cover changes, the model gives an increase in the decadal average of runoff by 8.5%. This agrees well with 10.5% increase in the actual stream flow as measured at Itaipu. There are three main conclusions from this work. First, the ED model is able to explain a major, paradoxical, reality in the Parana basin. Second, it is necessary to take into account both climate and land use changes when exploring past or future changes in river flows. Third, the ED model, now coupled with a regional climate model (i.e., EDBRAMS), is a sound basis for exploring likely changes in river flows in major South American rivers.

  11. Mid-21st-century climate changes increase predicted fire occurrence and fire season length, Northern Rocky Mountains, United States

    Riley, Karin L.; Loehman, Rachel A.

    2016-01-01

    Climate changes are expected to increase fire frequency, fire season length, and cumulative area burned in the western United States. We focus on the potential impact of mid-21st-century climate changes on annual burn probability, fire season length, and large fire characteristics including number and size for a study area in the Northern Rocky Mountains. Although large fires are rare they account for most of the area burned in western North America, burn under extreme weather conditions, and exhibit behaviors that preclude methods of direct control. Allocation of resources, development of management plans, and assessment of fire effects on ecosystems all require an understanding of when and where fires are likely to burn, particularly under altered climate regimes that may increase large fire occurrence. We used the large fire simulation model FSim to model ignition, growth, and containment of wildfires under two climate scenarios: contemporary (based on instrumental weather) and mid-century (based on an ensemble average of global climate models driven by the A1B SRES emissions scenario). Modeled changes in fire patterns include increased annual burn probability, particularly in areas of the study region with relatively short contemporary fire return intervals; increased individual fire size and annual area burned; and fewer years without large fires. High fire danger days, represented by threshold values of Energy Release Component (ERC), are projected to increase in number, especially in spring and fall, lengthening the climatic fire season. For fire managers, ERC is an indicator of fire intensity potential and fire economics, with higher ERC thresholds often associated with larger, more expensive fires. Longer periods of elevated ERC may significantly increase the cost and complexity of fire management activities, requiring new strategies to maintain desired ecological conditions and limit fire risk. Increased fire activity (within the historical range of

    Two sediment cores from Mauritia flexuosa palm swamps have been studied by pollen and charcoal analysis. The cores Fazenda Cigana (FC) and Terra Indígena Aningal (TIA) were taken from a savanna-forest ecotone area in the Roraima State, northern Brazilian Amazon. Based on 5 radiocarbon dates, these records allow the reconstruction of the vegetation fire and climate dynamics during the past 1550 years. At the FC site was recorded a higher proportion of forest cover, suggesting local wetter climatic conditions favorable for forest expansion, especially by gallery forests, between 1550 and 1400 cal yr BP. Stands of M. flexuosa started to establish on the site indicating sufficient soil moisture. From 1400 to 1050 cal yr BP, forest cover retreated while savanna, and the Mauritia palm swamp expanded considerably. The FC site was marked by savanna and Mauritia cover with a slight increase of forest between ca. 1050 and 900 cal yr BP. From 900 to 300 cal yr BP the savanna and palm swamp taxa became dominant and the forest area decreased. At the TIA site the savanna cover was dominant between 1200 and 1000 cal yr BP. From 1000 to 700 forest expanded while savanna and Mauritia palm swamp reduced. Between 700 and 300 cal yr BP savanna and Mauritia palm swamp increased and forest area decreased. The high amount of charred particles found in the sediments, indicate fires with a marked increase between 1400 to 1000 cal yr BP (FC site) and 700 to 300 cal yr BP (TIA site), and probably caused the retreat of forest cover during these two time intervals. The relatively lower fire activity after 300 cal yr BP until present-day favored the increase of forested area at both TIA and FC sites. The arrival of the European settler and the subsequent introduction of cattle, is suggested as the main reason for the decrease of fire in the study region. The results point the fire caused by indigenous people as the principal controlling factor for forest and savanna dynamics during the past

    The Paraná-Etendeka Volcanic Province records the volcanism of the Early Cretaceous that precedes the fragmentation of the South-Gondwana supercontinent. Traditionally, investigations of these rocks prioritized the acquisition of geochemical and isotopic data, considering the volcanic stack as a monotonous succession of tabular flows. Torres Syncline is a tectonic structure located in southern Brazil and where the Parana-Etendeka basalts are well preserved. This work provides a detailed analysis of lithofacies and facies architecture, integrated to petrographic and geochemical data. We identified seven distinct lithofacies grouped into four facies associations related to different flow morphologies. The basaltic lava flows in the area can be divided into two contrasting units: Unit I - pahoehoe flow fields; and Unit II - simple rubbly flows. The first unit is build up by innumerous pahoehoe lava flows that cover the sandstones of Botucatu Formation. These flows occur as sheet pahoehoe, compound pahoehoe, and ponded lavas morphologies. Compound lavas are olivine-phyric basalts with intergranular pyroxenes. In ponded lavas and cores of sheet flows coarse plagioclase-phyric basalts are common. The first pahoehoe lavas are more primitive with higher contents of MgO. The emplacement of compound pahoehoe flows is related to low volume eruptions, while sheet lavas were emplaced during sustained eruptions. In contrast, Unit II is formed by thick simple rubbly lavas, characterized by a massive core and a brecciated/rubbly top. Petrographically these flows are characterized by plagioclase-phyric to aphyric basalts with high density of plagioclase crystals in the matrix. Chemically they are more differentiated lavas, and the emplacement is related to sustained high effusion rate eruptions. Both units are low TiO2 and have geochemical characteristics of Gramado magma type. The Torres Syncline main valley has a similar evolution when compared to other Large Igneous Provinces

    Full Text Available The northern coast of Rio de Janeiro State lacks natural consolidate substrates, making it a proper environment to the development of researches using artificial structures. After studies about the type of substrate, concrete seems to be the most appropriate for studying fouling community development. This research was carried out to investigate the functional role of biofouling in the development of the ichthyic community in the north of Rio de Janeiro State. Percentage data of the epibenthic organisms' coverage and samples of the fish community with gillnet and visual census showed that biofouling in artificial reefs might have more than one functional role, acting as a facilitator in the recruitment of fish species and as a link in the trophic marine chain. Through the increase of localized structural complexity provided by the reef itself and by the fouling organisms which act as "engineering species", additional protection options are offered to the ichthyic community, especially recruits. Also, the epibiont biomass represents an important link in the food web, acting either as a direct source or in the transference of energy to higher trophic levels. Through the relationship between the ichthyic and fouling communities we concluded that the functional role of the latter in artificial reef habitats could be characterized mainly as shelter and feeding grounds for few fish species.O litoral norte do Estado do Rio de Janeiro possui uma escassez de substrato consolidado natural tornando o ambiente propício para o desenvolvimento de pesquisas com estruturas artificiais.

    After the expansion of agricultural frontier occurred in the southern brazilian region, which brought native forest substitution, new  management and alternatives practices were introduced in order to preserve and stimulate new plantings of the parana pine (Araucaria angustifolia . Alongside, in the last years, silviculturists have been promoting activities of forest development, in special with Pinus, Eucalyptus, Grevillea and bracatinga (Mimosa scabrella species to face wood depletion of native forest species. At the same time, new legal procedures also contributed to reduce new plantings of parana pine  because it tried to enforce simple preservation with high demands and tough inspection measures. Thus, representing 85 % of land structure in the State of Paraná, discouraged - small farmers were looking for to erradicate this species due to legal over regulation. Therefore, to  vercome this situation, mechanisms were offered to the silviculture management of Brazilian pine which were based in two central points tupgrading the existing laws and to incentive new plantations, specially in the areas set aside for environmental protection called of "Reserva Legal". In this way, the Extension Service (Emater tried to help this situation with the following prescription: technology diffusion; rewards to stimulate forest producers in the municipality; and formation of farmers groups to collect, select and to sell pine seeds.

    Structural features associated with aspects like migration routes, fluid convergence and/or barriers and seal integrity, among others, may be evaluated with the aid of information obtained by remote sensing and field data. This work is focused on the analysis of the geometry of tectonic structures and their relationship with essential elements of the Irati-Rio Bonito Petroleum System, inserted in the Parana Basin. The structural framework was outlined with satellite imagery, digital elevation models and geophysical maps. Several techniques relative to lineament analysis were reviewed and implemented by software programming. The description of structural styles, and kinematic and dynamic analysis were performed using field data obtained in key-areas. Another software was developed in order to calculate paleostress components. It computes maximum, intermediary and minor principal stress position based on Mohr-Coulomb criteria, for each fault individually. That aspect showed to be particularly important in this study due the several tectonic episodes that occurred in the Parana Basin. The relationships among features of different magnitudes and structural levels, interpreted by integrating several remote sensors, provided the understanding of the structural envelopment in the studied area. Based on the mapped structural elements, some accumulation controls were pointed out, such as the observed potential for the development of structural traps near regional structures, and the possibility of greater seals integrity associated with NE-SW oriented structural trends. Furthermore, N-S trending elements, generated in an extensional regime, could be associated with the rupture of the upper section, thus allowing leakage of hydrocarbon accumulations. (author)

    We present the state-of-the-art of the Greek Database of Seismogenic Sources (GreDaSS). The major goals of this international scientific project are (i) the systematic collection of all available information concerning active faults, potentially active faults and seismogenic volumes within the broader Aegean Region; (ii) the quantification of the principal seismotectonic parameters of the different sources as well as their degree of uncertainty; (iii) to supply an integrated view of potentially damaging seismogenic sources for a better assessment of the seismic hazard of Greece. The informatic framework of the database follows closely that used for the Italian Database of Individual Seismogenic Sources (DISS), which represents the result of more than ten years experience of its Working Group (e.g. Basili et al., 2008). This preliminary version of GreDaSS is focused on northern Greece, where we distinguish two main categories of Seismogenic Sources based on their attributes, their expected use, the nature and reliability of data used to define them: - "Individual Seismogenic Sources" (GGSources) are obtained from geological and geophysical data and are characterized by a full set of geometric (strike, dip, length, width and depth), kinematic (rake) and seismological-palaeoseismological parameters (average displacement, magnitude, slip rate, recurrence interval) and by a rating of the associated uncertainties. Individual Seismogenic Sources are assumed to exhibit "characteristic" behaviour with respect to rupture length/width and expected mean and maximum magnitude. They are tested against worldwide databases for internal consistence in terms of length, width, average displacement and magnitude. This category of sources favours accuracy of the information supplied over completeness of the sources themselves. As such, they can be used for deterministic assessment of seismic hazard, for calculating earthquake and tsunami scenarios, and for tectonic and geodynamic

The area is located between the cities of Campo Magro and Campo Largo, Paraná plateau in the first part of theAlto Iguaçu basin. This study aims to raise the concepts relating to environmental geomorphology, to identify the anthropogenic impacts caused in the reservoir areas, identify the environmental compartments found around the dam and characterize the geologic and physiographic region. It was found that the area has intense anthropogenic influence, as urban growth is present in areas and wavy and rough terrain, subject to mass movements and floods. Besides these aspects, the use of land for agriculture contributes to fragility of the area.

    High levels of radon concentration were found in the underground workplace of an underground coal mine in Parana state, which has been in activity since 1942. Many of these workers were exposed for a long period of time to a work atmosphere with high radon, and radon decay products concentration. Taking this into account, it was decided to carry on a historical cohort, study with the workers' of this mining universe (underground and surface) in. order to evaluate the possible health effects related to this exposure, by means of a retrospective study of mortality. Through multiple strategies, it was possible to trace the vital status of 90% of the cohort. The causes of the deaths were identified by active search, of Death Declarations in the Health Office of Parana state and also in and other states. The success rate of cause of death identification was 100%. The final, cohort included 1946 underground workers and 910 surface workers. Standard mortality ratio (SMR) analysis showed lower mortality from all causes for both underground (SMR-88, 95%CI=78-98) and surface workers (SMR=96, 95%CI=81- 113). A highly significant SMR was observed for pneumonia cause of death among surface ((SMR=284, 95%CI=118-684) and underground miners (SMR-254, 95%CI=140-459), while a highly significant lung cancer mortality risk was observed only for underground miners (SMR=177, 95%CI=105-299) with a significant trend in relation to years of underground work (duration of exposure). Taking into account that mortality from smoking-related cancers other than lung cancer is not elevated in underground workers and diesel equipment were not used at this mine, the results suggest that the exposure to radon daughters may have been responsible for the lung cancer excess among underground workers. This work consists of the first historical Brazilian cohort involving miners exposed to radon and one of the few historical cohorts built in Brazil. It should be considered the fact that many workers

    A six-State area in the northern Midwest of the United States has become increasingly dependent on ground water from the Cambrian-Ordovician aquifer system, which consists of a sequence of sandstones, carbonate rocks, and shales. Ground-water withdrawals from the aquifer system began in the late 1800's and increased to approximately 684 million gallons per day (1,058 cubic feet per second) by 1980. This withdrawal has caused more than 900 feet of decline in the potentiometric surface of the aquifer system in parts of the Chicago, Ill., area. Pumping in Minneapolis-St. Paul, Minn., Milwaukee, Wis., and central Iowa has produced a few hundreds of feet of water-level decline.

    A radiometric zircon age of 285.4 {+-} 8.6 Ma (IDTIMS U-Pb) is reported from a tonstein layer interbedded with coal seams in the Faxinal coalfield, Rio Grande do Sul, Brazil. Calibration of palynostratigraphic data with the absolute age shows that the coal depositional interval in the southern Parana Basin is constrained to the Sakmarian. Consequently, the basal Gondwana sequence in the southern part of the basin should lie at the Carboniferous-Permian boundary, not within the Sakmarian as previously considered. The new results are significant for correlations between the Parana Basin and the Argentinian Paganzo Basin (302 {+-} 6 Ma and 288 {+-} 7 Ma) and with the Karoo Basin, specifically with the top of the Dwyka Tillite (302 {+-} 3 Ma and 299.2 {+-} 3.2 Ma) and the lowermost Ecca Group (288 {+-} 3 Ma and 289.6 {+-} 3.8 Ma). The evidence signifies widespread latest Carboniferous volcanic activity in western Gondwana.

    Older adults are living longer and retaining their teeth, resulting in a concomitant increase in the need for oral care services. Despite improvements in oral health among the elderly, there continue to be profound disparities by race/ethnicity, socioeconomic and dentate status. Furthermore, challenges, such as limitations in activities of daily living, poor wheel-chair accessibility of dental clinics, poor geographic distribution of providers, difficulty navigating the oral health system and fiscal limitations make access to, and utilization of, dental services difficult among older adults. While dialogue around national policy, especially incorporation of dental benefits for adults in Medicare and Medicaid, is imperative, local efforts in New York and Northern Manhattan show promise in addressing the oral health and health care of older New Yorkers.

  12. Delimiting the origin of a B chromosome by FISH mapping, chromosome painting and DNA sequence analysis in Astyanax paranae (Teleostei, Characiformes.

    Directory of Open Access Journals (Sweden)

    Duílio M Z de A Silva

    Full Text Available Supernumerary (B chromosomes have been shown to contain a wide variety of repetitive sequences. For this reason, fluorescent in situ hybridisation (FISH is a useful tool for ascertaining the origin of these genomic elements, especially when combined with painting from microdissected B chromosomes. In order to investigate the origin of B chromosomes in the fish species Astyanax paranae, these two approaches were used along with PCR amplification of specific DNA sequences obtained from the B chromosomes and its comparison with those residing in the A chromosomes. Remarkably, chromosome painting with the one-arm metacentric B chromosome probe showed hybridization signals on entire B chromosome, while FISH mapping revealed the presence of H1 histone and 18S rDNA genes symmetrically placed in both arms of the B chromosome. These results support the hypothesis that the B chromosome of A. paranae is an isochromosome. Additionally, the chromosome pairs Nos. 2 or 23 are considered the possible B chromosome ancestors since both contain syntenic H1 and 18S rRNA sequences. The analysis of DNA sequence fragments of the histone and rRNA genes obtained from the microdissected B chromosomes showed high similarity with those obtained from 0B individuals, which supports the intraspecific origin of B chromosomes in A. paranae. Finally, the population hereby analysed showed a female-biased B chromosome presence suggesting that B chromosomes in this species could influence sex determinism.

    The objective of this work is to study natural radionuclides in sedimentary rocks. The concentration of them reflects the origin of the sediments, the depositional environment as well as some mineralogical characteristics of the rock matrix, and also more recent events as weathering and erosion. Using gamma ray high resolution spectrometry, the profile of activity concentration of the natural radionuclides was assessed for {sup 226}Ra, {sup 238}U, {sup 32}Th and {sup 40}K in rocks of the Irati Formation belonging to Parana Sedimentary Basin. The samples were collected at a limestone abandoned mine, in the city of Sapopema, (PR). 24 samples were collected, eleven from the exposed vertical profile with approximately 5.50 m, whose stratigraphy is represented by an alternation among decimetrics layers of limestones, bituminous shales, and some rhythmits layers (milimetric sheets of limestone and bituminous shales), 9 repetitions of a sample to study the variability, and three rigolits samples in sequential apprenticeships of weathering. Each sample was dried in the sun during about 48 hours, broken, drizzled in a sieve of 4 mesh and put, in a cylindrical container. The measures were accomplished using a Germanium Hyper Pure detector (HPGe) with relative efficiency of 66%, connected to a standard spectrometry electronic chain. The measured concentrations of activity of {sup 238}U were smaller for the limestones (17.80 {+-}0.09 Bq.Kg{sup -1}), larger for the bituminous shales (125.5 {+-} 2.6 Bq.Kg{sup -1} with enrichment of uranium in the sample (200), 548 {+-} 16 Bq.Kg{sup -1}, upper part of the column), and intermediate for the rhythmits (23.0 {+-} 1,3 Bq.Kg{sup -1}. The ratio eTh/K obtained for the studied profiles has equivalent values, indicating similar mineralogical characteristics for the limestones, bituminous shales, rhythmits and studied rigolits. On the other hand, to the ratio eTh/eU showed that two of the three regolits samples belong to oxidizer

    In this work, we consider application of an original method for determining the indicators of the tectonic stress fields in the northern Baikit anteclise based on 3D seismic data for further reconstruction of the stress state parameters when analyzing structural maps of seismic horizons and corresponded faults. The stress state parameters are determined by the orientations of the main stress axes and shape of the stress ellipsoid. To calculate the stress state parameters from data on the spatial orientations of faults and slip vectors, we used the algorithms from quasiprimary stress computation methods and cataclastic analysis, implemented in the software products FaultKinWin and StressGeol, respectively. The results of this work show that kinematic characteristics of faults regularly change toward the top of succession and that the stress state parameters are characterized by different values of the Lode-Nadai coefficient. Faults are presented as strike-slip faults with normal or reverse component of displacement. Three stages of formation of the faults are revealed: (1) partial inversion of ancient normal faults, (2) the most intense stage with the predominance of thrust and strike-slip faults at north-northeast orientation of an axis of the main compression, and (3) strike-slip faults at the west-northwest orientation of an axis of the main compression. The second and third stages are pre-Vendian in age and correlate to tectonic events that took place during the evolution of the active southwestern margin of the Siberian Craton.

    2014-03-01

    Full Text Available Looking into prison short fiction, this article discusses how a number of Northern Irish women writers have challenged male-centred narratives of the Troubles. Mary Beckett, Frances Molloy and Brenda Murphy have created alternative discourses of political violence which differ from the dominant narratives of incarceration. They confront established discourses of masculinity and femininity by subverting social constructs of gender, particularly the models of the rebel-hero and Mother Ireland ingrained in the nationalist/republican traditions. Their prison short stories are excellent examples of how state politics is superseded by gender politics in women’s writing and they are also proof of an emerging gender consciousness that challenged dominant readings of the Troubles in the last decades of the twentieth century.

    Determining factors that affect healthcare utilization by the elderly is vital for the health system to be more responsive in providing care to this vulnerable group. The main objective of this paper is to identify the effect of the predisposing, enabling, and need factors on doctor visits and in-patient care for the elderly residing in the northern region of Malaysia. A multistage cluster sampling was used in selecting the sample for the study. A total of 1414 respondents aged 60 and over were interviewed face-to-face using a structured questionnaire. A probit model was used in estimating the utilization equations. At a significance level of 0.05, except for age, all predisposing and enabling factors were not statistically significant in affecting the doctor visits. On the other hand, being a male, smoker, medical insurance holder or had not actively involved in social interaction within the reference period increases the likelihood of being in-patient. Health-related variables remain the most significant factors that determine healthcare utilization, including both doctor visits and in-patient stays, in the area of study, which suggests that government policies to improve population health may influence the level of healthcare use in the future.

    The objectives of this study were to estimate the stability of dry biomass production of elephant grass genotypes under an annual harvest regime, in soil-climatic conditions of the Northern region of the Rio de Janeiro State, Brazil, and to compare methodologies for stability analyses of Yates and Cochran (YC), Plaisted and Peterson (PP), Annicchiarico (ANN), Lin and Binns (LB), Huenh (HU), and Kang and Phan (KP). A randomized block design with 83 treatments and two replicates was adopted. Four annual harvests were performed (2012-2015) and dry matter yield (DMY, t.ha -1 .year -1 ) was evaluated. Individual and combined analyses of variance for DMY revealed significant effects for genotypes, harvests, and for the genotype x harvest interaction at the probability levels of 1 and 5%. Genotypes indicated by the YC and PP methods are associated with higher stability and lower DMY. The weighting of KP with YC and PP was highly effective in associating stability with DMY. The LB and ANN methods showed strong agreement with each other and produced similar classifications as to phenotypic stability, and so we recommend using one or the other. Genotypes Elefante Cachoeiro do Itapemirim, Cuba-116, Taiwan A-46, P241 Piracicaba, Taiwan A-144, Cameroon - Piracicaba, 10 AD IRI, Guaçu/I,Z,2, Mineirão IPEACO, Taiwan A-121, IJ7125 cv EMPASC308, 903-77, Mole de Volta Grande, and Porto Rico 534-B showed high stability and DMY, standing out as promising genotypes for the soil-climatic conditions of the Northern region of the Rio de Janeiro State. The methodologies based on ANOVA and non-parametric analyses were complementary and increased reliability in the recommendation of genotypes.

  20. A multi-state weather generator for daily precipitation for the Torne River basin, northern Sweden/western Finland

    Results showed that the 10-state empirical model represented accumulated 2- to 14-day precipitation most realistically. Further, the distribution of precipitation on wet days in the catchment is related to the placement of a wet day within a wet-spell, and the 10-state models represented this realistically, while the wet/dry models did not. Although all four models accurately reproduced the annual and monthly averages in the training data, all models underestimated inter-annual and inter-seasonal variance. Even so, the 10-state empirical model performed best. We conclude that the multi-state model is a promising candidate for hydrological applications, as it simulates multi-day precipitation well, but that further development is required to improve the simulation of interannual variation.

    This work presents the development of models for Calculated Cetane Index (CCI) determination with the purpose of tailor it to the diesel oil sold in Brazil, using optimization techniques. As the diesel is the main fuel on the Brazilian territory, their quality is of great importance. The CCI calculation is important to evaluate the diesel quality. The standard ASTM D 4737 does not take into account the presence of cetane booster additive and biodiesel, which creates the need to recast the equation of the CCI determination. About 300 representative samples were selected of diesel in Parana, during the 2006 to 2007 period, which had their physic-chemical properties determined using the methodology adopted by the ANP - the Brazilian petroleum, natural gas and biofuel agency. The Derived Cetane Number was obtained in the IQT apparatus and several models were proposed, all with better predictive capability than the equation of the standard ASTM D 4737. It is pointed out that biodiesel can act as cetane booster additive depending upon its origin, mostly in concentrations above 5%. The methodology can be expanded to generate a representative equation for the diesel sold in the whole Brazilian territory. (author)

    This work reports an alternative methodology for the linear attenuation coefficient determination ({mu} {rho}) of irregular form samples, in such a way that is not necessary to consider the sample thickness. With this methodology, indigenous archaeological ceramics fragments from the region of Londrina, north of Parana, were studied. These ceramics fragments belong to the Kaingaing and Tupiguarani traditions. The equation for the {mu} {rho} determination employing the two mean method was obtained and it was used for {mu} {rho} determination by the gamma ray beam attenuation if immersed ceramics, by turns, in two different means with known linear attenuation coefficient. By the other side, {mu} theoretical value was determined with the XCOM computer code. This code uses as input the ceramics chemistry composition and provides an energy versus mass attenuation coefficient table. In order to validate the two mean method validation, five ceramics samples of thickness 1.15 cm and 1.87 cm were prepared with homogeneous clay. Using these ceramics, {mu} {rho} was determined using the attenuation method, and the two mean method. The result obtained for {mu} {rho} and its respective deviation were compared for these samples, for the two methods. With the obtained results, it was concluded that the two means method is good for the linear attenuation coefficient determination of materials of irregular shape, what is suitable, specially, for archaeometric studies.

    This paper presents an analytical view of the palynostratigraphy of the Pennsylvanian-Permian interval of the Parana Basin, emphasizing the importance of the contributions by R. F. Daemon and L. P. de Quadros, published in 1970. The main characteristics of this zonal scheme are presented, with emphasis on its operability in geological studies on the relative ages and correlation. The proposed intervals correspond to stratigraphical units interpreted as meaning 'time-rock', which are traceable for short and long distances, and embracing various depositional environments. Because they occur in distinct lithostratigraphical units, they are significant for their potential in paleogeographic reconstructions. The importance in stratigraphical chart constructions for the basin is highlighted, as well as the exposure of some modern stratigraphic concepts used by the authors, innovations at that time, such as the attention to certain biostratigraphic criteria and the recognition of the maximum flooding surfaces. The current zonal scheme is presented, with the due integration and bio chronostratigraphic updating. Furthermore, the main goals for studies on this theme in the near future are shown. (author)

    Deep Andean earthquakes are a suitable source of high-frequency P-waves (with good signal to noise ratio up to {approx} 10 Hz) that can be used to obtain high-resolution receiver functions at stations in intra-cratonic basins in Brazil. Receiver functions (Gaussian width 20) at five stations in the Bebedouro seismic area (NE Parana Basin) were calculated using the time domain deconvolution of Ligorria and Ammon (1999). Inter-station Rayleigh wave phase velocities were measured using local earthquakes. Joint inversion of receiver functions and Rayleigh phase velocities provided reasonably well constrained S-wave velocity profiles. Shallow seismic refraction surveys were used to fix the velocities of the surface layers during the inversion. The area is characterized by a thin surface layer of sandstones ({approx}60 m), followed by a {approx}500 m thick basalt layer. Beneath the basalts, low-velocity layers define another sedimentary sequence. These features are consistent with the expected values based on well data at regional distances and confirm the usefulness of high-frequency receiver functions to study sedimentary basins. (author)

    Uranium is a litophile element that migrates to crust together with other light silicates. This work evaluated the relationships among the concentrations of uranium, major oxides (SiO{sub 2}, Al{sub 2}O{sub 3}, Na{sub 2}O, K{sub 2}O, CaO, MgO, Fe{sub 2}O{sub 3}, MnO, TiO{sub 2}, P{sub 2}O{sub 5}) and organic matter in different horizons of a soil profile located over siltstone from Tatui Formation, Piracicaba River sub-basin, Sao Paulo State, Brazil. Different techniques were utilized for data acquisition, for instance, alpha spectrometry, X-ray fluorescence spectrometry and smectrophotometry. The major U concentrations were found in horizons enriched in Fe{sub 2}O{sub 3}, indicating its tending to be retained in iron oxides. (author)

    The NOx (NO and NO2) and HOx (OH and HO2) budgets of the atmosphere exert a major influence on atmospheric composition, controlling removal of primary pollutants and formation of a wide range of secondary products, including ozone, that can influence human health and climate. However, there remain large uncertainties in the changes to these budgets over recent decades. Due to their short atmospheric lifetimes, NOx and HOx are highly variable in space and time, and so the measurements of these species are of limited value for examining long-term, large-scale changes to their budgets. Here, we take an alternative approach by examining long-term atmospheric trends of alkyl nitrates, the production efficiency of which is dependent on the atmospheric [NO] / [HO2] ratio. We derive long-term trends in the alkyl nitrates from measurements in firn air from the NEEM site, Greenland. Their mixing ratios increased by a factor of 3-5 between the 1970s and 1990s. This was followed by a steep decline to the sampling date of 2008. Moreover, we examine how the trends in the alkyl nitrates compare to similarly derived trends in their parent alkanes (i.e. the alkanes which, when oxidised in the presence of NOx, lead to the formation of the alkyl nitrates). The ratios of the alkyl nitrates to their parent alkanes increased from around 1970 to the late 1990s. This is consistent with large changes to the [NO] / [HO2] ratio in the Northern Hemisphere atmosphere during this period. Alternatively, they could represent changes to concentrations of the hydroxyl radical, OH, or to the transport time of the air masses from source regions to the Arctic.

    Full Text Available The aim of this study was to determine the occurrence of intestinal parasites in a quilombola community from the northern Espírito Santo, Brazil. Descendants of slaves who arrived in Brazil in the sixteenth century, this population settled in the municipality of São Mateus in 1858. Fresh fecal samples from 82 individuals who agreed to participate in the study were collected between August 2009 and July 2010, and immediately sent to the Clinical Laboratory of the Centro Universitário Norte do Espírito Santo of the Universidade Federal do Espírito Santo for analysis. Out of all the participants, 36 (43.9% were male and 46 (56.1% were female, whose ages ranged from six to 85 years. The study of the occurrence of intestinal parasites indicated that 35 individuals (42.7% were infected with at least one intestinal parasite. Among helminths, the most frequent were hookworms, with a rate of 14.6%. With regard to protozoa, Entamoeba coli, Entamoeba histolytica/Entamoeba dispar and Endolimax nana stood out, with frequencies of 23.2%, 8.5% and 4.9%, respectively. The occurrence of biparasitism was observed in 13 of the 82 subjects, accounting for 15.8%, and no cases of multiple parasitic infections were observed. It was concluded that the reduction of cases of intestinal diseases due to parasites will only be achieved with the improvement of basic sanitation and quality of life of quilombola populations.

    Full Text Available The purpose of this study is identifying and scaling all the dynamics that mediate the relationship between the state and the criminal organization. Also, the way this fits into the context of economic globalization, evolving along with processes that are disaggregating competencies that have made its historical development more complex and caused it to collide with the empowerment of new non-state stakeholers vying for jurisdiction and influence in various aspects such as territorial presence, local economy and social control. In this sense, the study exposes the actions and omissions of the State as the main inputs generating the present adverse security environment throughout the Mesoamerican area. This is collected systematically in a synthesized working hypothesis.The challenge lies in exploring the likely thresholds for reconstituting the immune system of the state construct, as an indispensable resource in the fight against criminal powers. Considering it a general effort, this extends to its ability to adapt in real and virtual environments that constantly undermine the attribute of the sovereign state.DOI: http://dx.doi.org/10.5377/rpsp.v1i2.1364

    Major and minor components of 30 acid and basic igneous rocks (granites, syenites, riolites and a basalt) of the Parana state crystalline basement were determined by X-ray fluorescence spectrometry (WDXRF), in order to evaluate the similarity in terms of the compositional content. The corrections of interelements effects (absorption/intensification) were performed by means of the fundamental parameters (FP) method. The methodology was validated using a certificated reference material. The main oxides found associated with the quantified elements are SiO{sub 2}, Al{sub 2}O{sub 3}, Na{sub 2}O, K{sub 2}O, Fe{sub 2}O{sub 3}, CaO, MgO, TiO{sub 2}, P{sub 2}O{sub 5}, MnO, SO{sub 3}, NiO, ZnO, Rb{sub 2}O. Through statistical analysis, the studied samples were organized in 3 groups of similar compositions: syenites, light granites and basalt and dark granites. The results show that the WDXRF technique is a robust tool that enables distinction even between similar geological samples. (author)

    Ion microprobe (SHRIMP II) dating of zircons from tonsteins interbedded with coal seams from the Candiota and Faxinal coalfields (Early Permian, Rio Bonito Formation, Parana Basin, Brazil) is presented. The mean ages obtained (290.6 {+-} 1.5 Ma) are more precise than previously published intervals. Calibrations of chronostratigraphic data with radiometric ages show that the main coal succession from the southern Basin is constrained to the Middle Sakmarian. The {+-} 2 Ma time interval of deposition supports the hypothesis that the coal-generating process was quite rapid in terms of geological time. In a general context, Faxinal and Candiota coals are assigned, into the Protohaploxypinus goraiensis Subzone, besides some paleocological differences evidenced by palynological studies. This bio-interval does not correspond to a consistent palynostratigraphic tool and more accurate biostratigraphic zonation for the Carboniferous-Permian interval must be delineated. The new results have far-reaching significance for correlations of the Basin with sequences of the Argentinian Paganzo Basin (302 {+-} 6 Ma and 288 {+-} 7 Ma) and also with the Karoo Basin, with the lowermost Ecca Group (288 {+-} 3 Ma and 289.6 {+-} 3.8 Ma). This new evidence supports the presence of an active and widespread Lower Permian explosive volcanic event in western Gondwana, which is interpreted as the same volcanism which produced the Choiyoi Group in western Argentina. According to this correlation the ash-fall source is located about 1400 km to the southwest of their area of deposition. (author)

    The rare earth elements (REE) distribution patters in igneous rocks of the Serra do Carambei Granite area (Parana) were a very important tool to elucidate the genetic processes and the cogenetic relationships between these rocks. The porphyroid facies of the Cunhaporanga Granitoid Complex has a REE distribution pattern characterized by decreasing concentrations in direction to the heavy rare earth elements (HREE) and the smooth Eu negative anomalie, compatible with amphibole fractionation during the magma ascent and the incipient plagioclase fractionation. The REE pattern of the Serra do Carambei Granite is characterized by the strong Eu negative anomalie, by the light rare earth element (LREE) depletion and by the HREE increase. This shape of the REE patterns is frequently observed in Sn-W granites, according to French authors. However in the igneous rocks of the Serra do Carambei Granite area this is not true. ''Rhyolite'' dytes intrusives in the Serra do Carambei Granite exhibit REE pattern similar to the wall rock, indicating then the same genetic processes. The Castro Group rhyolites have REE patterns with decreasing concentrations in direction to the HREE and smooth Eu negative anomalie. The REE distribution patterns is against the consanguinity between the ''rhyolites'' intruded in the Serra do Carambei Granite and the rhyolites of the Castro Group and also between these rhyolites and the above mentioned Granite.

    The biological invasion process is widely debated topic, as the population depletion of some species and the extinction of others are related to this process. To accelerate the identification of species and to detect non-native forms, new tools are being developed, such as those based on genetic markers. This study aimed to use Barcode DNA methodology to identify fish species that had translocated between the Parana and Paraguay River Basins. Based on a database of two studies that were conducted in these regions, 289 sequences of Cytochrome Oxidase C subunit 1 (COI) were used for General Mixed Youle Coalecent (GMYC) analysis, including 29 morphospecies that were sampled in both river basins. As a result, we observed that while some morphospecies have low variation, demonstrating a recent occupation of the basins, other morphospecies probably represent species complexes. A third of the morphospecies had well-defined lineages but not enough to be treated as different Molecular Operational Taxonomic Units (MOTUs). These results demonstrate that human interventions possibly participated in the distribution of some lineages. However, biogeographical historical processes are also important for the morphospecies distribution. The data suggest that the number of species that are present in these two basins is underestimated and that human actions can irreversibly affect the natural history of the species in these regions.

    Maternal mortality ratio and infant mortality rate are as high as 1,576 per 100,000 live births and 78 per 1,000 live births, respectively, in Nigeria's northwestern region, where Sokoto State is located. Using applicable monitoring indicators for tracking progress in the UN/WHO framework on continuum of maternal, newborn, and child health care, this study evaluated the progress of Sokoto toward achieving the Millennium Development Goals (MDGs) 4 and 5 by December 2015. The changes in outcomes in 2012-2013 associated with maternal and child health interventions were assessed. We used baseline and follow-up lot quality assurance sampling (LQAS) data obtained in 2012 and 2013, respectively. In each of the surveys, data were obtained from 437 households sampled from 19 LQAS locations in each of the 23 local government areas (LGAs). The composite state-level coverage estimates of the respective indicators were aggregated from estimated LGA coverage estimates. None of the nine indicators associated with the continuum of maternal, neonatal, and child care satisfied the recommended 90% coverage target for achieving MDGs 4 and 5. Similarly, the average state coverage estimates were lower than national coverage estimates. Marginal improvements in coverage were obtained in the demand for family planning satisfied, antenatal care visits, postnatal care for mothers, and exclusive breast-feeding. Antibiotic treatment for acute pneumonia increased significantly by 12.8 percentage points. The majority of the LGAs were classifiable as low-performing, high-priority areas for intensified program intervention. Despite the limited time left in the countdown to December 2015, Sokoto State, Nigeria, is not on track to achieving the MDG 90% coverage of indicators tied to the continuum of maternal and child care, to reduce maternal and childhood mortality by a third by 2015. Targeted health system investments at the primary care level remain a priority, for intensive program scale-up to

    The aim of the present study was to evaluate the helminth fauna found in the Magellanic penguin, Spheniscus magellanicus, relating parasite population and community ecological parameters to life aspects of the host species. The study involved 237 specimens of S. magellanicus taken from the northern shore of the state of São Paulo (23° 46' S, 45° 57' W) and southern shore of the state of Rio de Janeiro (23° 02' S, 44° 13' W), Brazil. The following helminth fauna were found: the nematode Contracaecum pelagicum (core species), found in the stomach; the digenetic Cardiocephaloides physalis and the cestode Tetrabothrius lutzi (satellite species), both collected from the initial portion of the small intestine. Comparisons using the Shannon Diversity Index revealed that the parasite community in juvenile penguins is less diverse in the migratory season than the breeding season. Parasitological studies on penguins and other migratory animals provide important information on species during the time in which they remain pelagic and constitute a useful tool for the acquisition of data that is difficult to obtain through other means, thereby favoring the conservation of the species.

    In western New York State interbedded pyritic silty green and dark grey shales and siltstone of the Hanover Member, Java Formation, West Falls Group, are overlain by thick pyritic dark grey-black shale of the Dunkirk Member of the Canadaway formation. The dark shales in the upper Hanover and Dunkirk contain a diverse and well preserved conodont fauna which allows precise placement of the Frasnian-Famennian boundary at several described sections. At Pt. Gratiot, in far western New York State, the contact between the Hanover and Dunkirk is disconformable. The Frasnian-Famennian boundary is marked by a pyritic lag deposit at the base of the Dunkirk which contains Palmatolepis triangularis and Pa. subperlobata. The underlying upper Hanover is characterized by Pa. bogartensis , Pa. cf. Pa. rhenana, Pa. winchelli, and Ancyrognathus (asymmetricus/calvini) Eastward, in the direction of the paleo-source area, the Frasnian-Famennian boundary is within the upper Hanover Member. At Irish Gulf the boundary is recognized within a 10 cm thick laminated pyritic dark grey shale bed 3.0 m below the base of the Dunkirk. Palmatolepis triangularis and Pa. subperlobata occur below a conodont-rich lag layer in the upper 2 cm of the bed. Palmatolepis bogartensis , Pa. cf. Pa. rhenana, Ancyrodella curvata, and Icriodus alternatus occur in the underlying 8 cm. Palmatolepis triangularis and Pa. winchelli occur in an underlying dark shale bed separated from the boundary bed by a hummocky cross-bedded siltstone layer.

    Microdeletions of chromosome 22 are common and have a prevalence of at least 1/4 000. Cardiac abnormalities, abnormal facial features and palatal abnormalities are frequently present in these patients. To describe the cardiac lesions and selected measurable facial features in children from the Free State and Northern Cape presenting at the Cardiology Unit of the Universitas Academic Hospital complex in Bloemfontein. This was a prospective study in which patients with abnormal facial characteristics were tested using a fluorescence in situ hybridisation (FISH) probe for the 22q11.2 microdeletion. Forty children tested positive for the microdeletion. All patients underwent an echocardiogram and where possible, facial anthropometric measurements were performed. The median age at diagnosis was 3.6 years (range 0.04 years, i.e. 2 weeks to 16.2 years). Tetralogy with or without pulmonary atresia was diagnosed in 43% (n = 17) of the children and truncus arteriosus in 20% (n = 8). A rightsided aortic arch was present in 43% (n = 17) of the patients. Mid-facial height was slightly longer (median = 1.0; range -0.5 to 3.3) and width narrower (median = -1.4; range -2.2 to 0.1) than normal. Ear height and width were notably small compared to normal, with median -scores = -3.3 (range -4.8 to -2.6) and = -2.4 (range -3.4 to -1.4), respectively. Microdeletions of chromosome 22q11 are present in children from the Free State and Northern Cape. Conotruncal cyanotic heart lesions, especially tetralogy with or without pulmonary atresia and truncus arteriosus were the most frequent congenital cardiac diagnoses. A right-sided aortic arch was also commonly present in these children. Facial features varied and small ears were the most noteworthy anthropometric feature. A right-sided aortic arch with or without a congenital cardiac lesion, a long, narrow mid-face and small ears should alert the physician to the possibility of a microdeletion on the long arm of chromosome 22.

    1994-08-01

    The determination of the hydraulic conductivity of a Red-Yellow Podzolic Soil was carried out during an experiment in a plot measuring 3.5 m x 3.5 m, at the Experimental Station of Itapirema, Goiania, in Pernambuco State, Brazil. The internal drainage method proposed by Hillel (1972) was used to obtain the hydraulic conductivity as a function of soil water content, K(θ), in the three characteristic horizons of the soil. Three neutron probes were used for measuring the humidity, that was determined by a calibration curve. Three characteristic horizons of the Red-Yellow Podzolic Soil were investigated for hydraulic conductivity. The sandy A horizon, with large pores, has a high conductivity while the B1t horizon, with a massive structure and few visible pores, has a low infiltration rate. The hydraulic dynamics of the B2 horizon is more complex due to its heterogeneity. (author). 79 refs, 17 figs, 11 tabs

    On April 2002 a 200KW Phosphoric Acid Fuel Cell (PAFC) Power Plant. was installed at LACTEC Institute For Technology Development, Research and Development facilities. The power plant installed at LACTEC site is the second of its kind in the Southern Hemisphere. Its presence, not only contributed to the creation of a Fuel Cell Stationary Power market for Brazil and the rest of the region, but increased the knowledge about fuel cell technology, and marked the point of entry as a reference for the education of a new generation of applied scientists. On its first year the power plant has operated 8,558 hours achieving an availability factor of 97% and supplying 730.50MWh of premium energy. As a second regional experience with fuel cell technology, we expect this report about LACTEC PACFC power plant performance, applications and cost-benefit evaluation will provide relevant information for future regional investments on this technology.

    Palynological analysis of pollen, Pteridophyta spores and algae deposited in the superficial sediments at Lagoa de Cima and Lagoa do Campelo Lakes, located in the north of Rio de Janeiro state, was used to determine the spatial variation of the palynomorphs deposition. A total of 67 pollen types were identified at Lagoa de Cima, with an expressive contribution of regional arboreous taxa, hydrophytes and ruderal plants of the pastureland. The depositional pattern of palynomorphs depends on the fluvial leakage, the proximity of the local sedimentation to the inlet of the Imbé and Urubu Rivers and the bathymetry of lake bottom. The highest concentrations of palynomorphs were observed in the decentralized and less deeper area, without the interference of the northeastern wind. At Lagoa do Campelo, a total of 58 pollen types were identified, among which the majority of the pollen grains came from hydrophytes, with the highest concentrations found along the northeastern shore. The southeastern shore showed high percentages of pollen and spores with degraded exine and mechanical damage, due to the transport through the lake by the currents caused by the wind, confirmed by the depositional trend of damaged palinomorphs along the same direction as the prevailing winds.

    In the current study, water quality of five river sites in Parana River basin (Brazil), utilized for public water supply, was assessed through a set of biomarkers in fish Astyanax spp. Population growth and inadequate use of land are challenges to the preservation of biodiversity and resources such as water. Some physicochemical parameters as well as somatic indexes, gills and liver histopathology, genotoxicity, and biochemical biomarkers were evaluated. The highest gonadosomatic index (GSI) and antioxidant parameters (catalase and glutathione S-transferase activities, non-protein thiols), as well as the lowest damage to biomolecules (lipid peroxidation, protein carbonylation, DNA damage) were observed in site 0 (Piava River), which is located at an environmental protected area. Site 1, located in the same river, but downstream site 0 and outside the protection area, presents some level of impact. Fish from site 2 (Antas River), which lack of riparian forest and suffer from silting, presented the highest micronucleus incidence and no melanomacrophages. Differently, individuals from site 3 (Xambrê River) and site 4 (Pinhalzinho River) which receive surface runoff from Umuarama city, urban and industrial sewage, have the highest incidences of liver and gill histopathological alterations, including neoplasia, which indicated the worst health conditions of all sites. In particular, site 4 had high levels of total nitrogen and ammonia, high turbidity, and very low oxygen levels, which indicate important chemical impact. Comparison of the biomarkers in fish allowed classification of the five sites in terms of environmental impact and revealed that sites 3 and 4 had particular poor water quality.

The experiment was arranged in a randomized block design, with three replications. The two main economic traits of the crops, grain yield (GY and popping expansion (PE, were assessed. In the joint analysis of variance, significant differences were observed using the F test for the GY and PE traits. Regarding the genotype x environment interaction, only the GY was significant, thus revealing that the cultivar behavior varies according to the environment. The Pi statistics and the results for those traits showed that UNB2U-C5 and hybrid P1 x P7 have the potential to be recommended as new alternatives for producers in the region.

    We developed and evaluated a methodology for subpixel discrimination and large-area mapping of the perennial warm-season (C4) grass component of vegetation cover in mixed-composition landscapes of the southwestern United States and northern Mexico. We describe the methodology within a general, conceptual framework that we identify as the differential vegetation phenology (DVP) paradigm. We introduce a DVP index, the Normalized Difference Phenometric Index (NDPI) that provides vegetation type-specific information at the subpixel scale by exploiting differential patterns of vegetation phenology detectable in time-series spectral vegetation index (VI) data from multispectral land imagers. We used modified soil-adjusted vegetation index (MSAVI2) data from Landsat to develop the NDPI, and MSAVI2 data from MODIS to compare its performance relative to one alternate DVP metric (difference of spring average MSAVI2 and summer maximum MSAVI2), and two simple, conventional VI metrics (summer average MSAVI2, summer maximum MSAVI2). The NDPI in a scaled form (NDPIs) performed best in predicting variation in perennial C4 grass cover as estimated from landscape photographs at 92 sites (R2 = 0.76, p phenology.

    The objective of this study was to evaluate the general practitioners' (GPs') knowledge and perceptions towards generic medicines in a northern state of Malaysia. A postal cross-sectional survey involving registered GPs in Penang, Malaysia was undertaken. A 23-item questionnaire was developed, validated and administered on the GPs. Eighty-seven GPs responded to the survey (response rate 26.8%). The majority of the respondents (85.1%) claimed that they actively prescribed generic medicines in their practice. On the other hand, only 4.6% of the respondents correctly identified the Malaysia's National Pharmaceutical Control Bureau's bioequivalence standard for generic products. There were misconceptions among the respondents about the concepts of "bioequivalence", "efficacy", "safety", and "manufacturing standards" of generic medicines. GPs in this survey believed that a standard guideline on brand substitution process, collaboration with pharmacists, patient education and information on safety and efficacy of generic medicines were necessary to ensure quality use of generics. Furthermore, advertisements and product bonuses offered by pharmaceutical companies, patient's socio-economic factors as well as credibility of manufacturers were factors reported to influence their choice of medicine. Although it appeared that GPs have largely accepted the use of generic medicines, they still have concerns regarding the reliability and quality of such products. GPs need to be educated and reassured about generic products approval system in Malaysia concerning bioequivalence, quality, and safety. The current findings have important implications in establishing generic medicines policy in Malaysia. Copyright (c) 2009 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Coexistence of folic acid and vitamin B12 deficiency has been observed among adolescents with iron deficiency anemia, but limited evidence is available from India. So, a rapid assessment was done to study the prevalence of iron, folic acid, and vitamin B12 deficiency among adolescent males and females in northern Himalayan state in India. Methods. Total 885 (female: 60.9% adolescents (11 to 19 completed years were surveyed from 30-cluster village from two community development blocks of Himachal Pradesh. Serum ferritin, folic acid, and vitamin B12 were estimated among randomly selected 100 male and 100 female adolescents. Results. Under-nutrition (BMI < 18.5 kg/m2 was observed among 68.9% of adolescents (male: 67.1%; female: 70.7; . Anemia was observed to be prevalent among 87.2% males and 96.7% females (. Mild form of anemia was observed to be the most common (53.9% form followed by moderate (29.7% anemia. Strikingly, it was found that all the adolescents were deficient in vitamin B12 and none of the adolescents was observed to be deficient in folic acid. Conclusion. Among both male and female adolescents anemia with vitamin B12 deficiency was observed to be a significant public health problem. Folic acid deficiency was not observed as a problem among surveyed adolescents.

  17. Climatic impact on isovolumetric weathering of a coarse-grained schist in the northern Piedmont Province of the central Atlantic states

    1993-01-01

    The possible impact of periglacial climates on the rate of chemical weathering of a coarse-grained plagioclase-muscovite-quartz schist has been determined for a small watershed near Baltimore, Maryland. The isovolumetric chemical weathering model formulated from the geochemical mass balance study of the watershed shows that the weathering front advances at a velocity of 9.1 m/m.y., if the modern environmental parameters remain the same back through time. However, recent surficial geological mapping demonstrates that periglacial climates have impacted the area. Such an impact significantly affects two key chemical weathering parameters, the concentration of CO2 in the soil and groundwater moving past the weathering front. Depending upon the assumptions used in the model, the rate of saprolitization varies from 2.2 to 5.3 m/m.y. The possible impact of periglacial processes suggested by the chemical weathering rates indicates a need to reconsider theories of landscape evolution as they apply to the northern Piedmont Province of the mid-Atlantic states. I suggest that from the Late Miocene to the present that the major rivers have become incised in their present locations; this incision has enhanced groundwater circulation and chemical weathering such that crystalline rocks beneath interfluvial areas remain mantled by saprolite; and the saprolite mantle has been partially stripped as periglacial conditions alternate with humid-temperate conditions. ?? 1993.

    An experiment was conducted at Merowe Research Station farm, in the Northern State, Sudan, during 2008/2009 and 2009/2010 seasons. The objectives of the experiment were to determine the damage inflicted by a wild sorghum species (Sorghum arundinaceum (Del.) Stapf. ) on the yield of faba bean (Vicia faba L.) and to evaluate the efficacy of the post-emergence herbicide clodinafop-propargyl (Topik) on wild sorghum and its effect on faba bean yield. The wild sorghum reduced faba bean crop stand and straw and seed yields by 53% - 76%, 76% - 79% and 88% - 91%, respectively, compared with the hand-weeded control. Faba bean was tolerant to the herbicide. The herbicide, at all rates, effected complete (100%) and persistent control of the wild sorghum and resulted in faba bean seed yield comparable to the hand-weeded control. The lowest dose (0.075 kg a.i/ha) of the herbicide used was equal to 75% of the dose recommended for the control of wild sorghum in wheat. It is concluded that clodinafop-propargyl at 0.075 kg a.e/ha could be used in controlling wild sorghum in faba bean. At this rate, the marginal rate of return was about 35 which indicating that every monetary unit (SDG 1) invested in the mentioned treatment would be returned back, plus additional amount of 35 SDG.(Author)

    Reproductive diseases limit the productivity of cattle worldwide and represent an important obstacle to profitable cattle enterprise. In this study, herd brucellosis and bovine genital campylobacteriosis (BGC) status, and demographic and management variables were determined and related to predicted calving rate (PrCR) of cattle herds in Adamawa, Kaduna and Kano states, Nigeria. Serum samples, preputial scrapings, questionnaire data, trans-rectal palpation and farm records were used from 271 herds. The Rose-Bengal plate test and competitive enzyme-linked immunosorbent assay were used for Brucella serology and culture and identification from preputial samples for BGC. A herd was classified as positive if one or more animals tested positive. The PrCR was determined as the number of calvings expected during the previous 6 and next 6 months as a percentage of the number of postpubertal heifers and cows in the herd. A multilevel linear regression model was used to estimate the herd-level effect of Brucella abortus seropositivity, Campylobacter fetus infection and other factors on calculated PrCR. The reproductive performance of the cattle herds was generally poor: Only 6.5% of the nursing cows were pregnant and 51.1% were non-pregnant and acyclic; the mean annual PrCR was 51.4%. Brucella abortus and C. fetus infection of herds were independently associated with absolute reduction in PrCR of 14.9% and 8.4%, respectively. There was also a strong negative association between within-herd Brucella seroprevalence and PrCR. Presence of small ruminants, animal introduction without quarantine and the presence of handling facilities were associated with lower PrCR, whereas larger herd size, supplementary feeding, routine mineral supplementation and care during parturition were associated with higher PrCR. Brucellosis and BGC may be largely responsible for the poor reproductive performance of indigenous Nigerian cattle. Farmer education and measures to improve the fertility of

    This medium-sized dabbling duck of slender, elegant lines and conservative plumage coloration is circumpolar in distribution and abundant in North America, with core nesting habitat in Alaska and the Prairie Pothole Region of southern Canada and the northern Great Plains. Breeders favor shallow wetlands interspersed throughout prairie grasslands or arctic tundra. An early fall migrant, the species arrives on wintering areas beginning in August, after wing molt, often forming large roosting and feeding flocks on open, shallow wetlands and flooded agricultural fields. The birds consume grains, marsh plant seeds, and aquatic invertebrates throughout fall and winter.Northern Pintails are among the earliest nesting ducks in North America, beginning shortly after ice-out in many northern areas. Individuals form new pair bonds each winter but are highly promiscuous during the nesting season, with mated and unmated males often involved in vigorous, acrobatic Pursuit Flights. Annual nest success and productivity vary with water conditions, predation, and weather. Females build nests on the ground, often far from water. Only the female incubates; her mate leaves shortly after incubation begins. Ducklings hatch together in one day, follow the female to water after a day in the nest, and fledge by July or August. Adults and ducklings consume mainly aquatic invertebrates during the breeding season.Predators and farming operations destroy many thousands of Northern Pintail nests annually; farming has also greatly reduced the amount of quality nesting cover available. Winter habitats are threatened by water shortages, agricultural development, contamination, and urbanization. Periods of extended drought in prairie nesting regions have caused dramatic population declines, usually followed by periods of recovery. Over the long term, however, the continental population of Northern Pintails has declined significantly from 6 million birds in the early 1970s to less than 3 million in

    A succession of Devonian cover rocks occurs in outcrop and in the subsurface of central-northern Uruguay where they were deposited in an intracratonic basin. This Durazno Group comprises three distinct stratigraphic units, namely the Cerrezuelo, Cordobés and La Paloma formations. The Durazno Group does not exceed 300 m of average thickness and preserves a transgressive-regressive cycle within a shallow-marine siliciclastic shelf platform, and is characterized by an assemblage of invertebrate fossils of Malvinokaffric affinity especially within the Lower Devonian Cordobés shales. The sedimentary provenance of the Durazno Group was determined using petrography, geochemistry, and morphological studies of detrital zircons as well as their U-Pb ages. Sandstone petrography of Cerrezuelo and La Paloma sequences shows that they have a dominantly quartz-feldspathic composition with a minor contribution of other minerals. Whole-rock geochemical data indicate that alteration was strong in each of the three formations studied; chondritic-normalized REE patterns essentially parallel to PAAS, the presence of a negative Eu-anomaly, and Th/Sc and La/Hf ratios point to an average source composition similar to UCC or slightly more felsic. Within the Cerrezuelo Formation, recycling of older volcano-metasedimentary sources is interpreted from Zr/Sc ratios and high Hf, Zr, and REE concentrations. U-Pb detrital zircon age populations of the Cerrezuelo and La Paloma formations indicate that the principal source terranes are of Neoproterozoic age, but include also minor populations derived from Mesoproterozoic and Archean-Paleoproterozoic rocks. A provenance from the Cuchilla Dionisio-Dom Feliciano, Nico Pérez and Piedra Alta terranes of Uruguay and southern Brazil is likely. This study establishes an intracratonic extensional tectonic setting during Durazno time. Considering provenance age sources, regional paleocurrent distributions and the established orogenic history recorded in SW

    2012-01-01

    This report provides a regional assessment of groundwater quality of the Cambrian-Ordovician aquifer system, based primarily on raw water samples collected by the NAWQA Program during 1995 through 2007. The NAWQA Program has published findings in local study-unit reports encompassing parts of the Cambrian-Ordovician aquifer system. Data collected from the aquifer system were used in national synthesis reports on selected topics such as specific water-quality constituent classes, well type, or aquifer material; however, a synthesis of groundwater quality at the principal aquifer scale has not been completed and is therefore the major purpose of this report. Water samples collected by the NAWQA Program were analyzed for various classes of characteristics including physical properties, major ions, trace elements, nutrients and dissolved organic carbon, radionuclides (tritium, radon, and radium), pesticides, and volatile organic compounds. Subsequent sections of this report provide discussions on these classes of characteristics. The assessment objectives of this report are to (1) summarize constituent concentrations and compare them to human-health benchmarks and non-health guidelines; (2) determine the geographic distribution of constituent concentrations and relate them to various factors such as confining conditions, well type, land use, and groundwater age; and (3) evaluate near-decadal-scale changes in nitrate concentrations and pesticide detections. The most recent sample collected from each well by the NAWQA Program was used for most analyses. Near-decadal-scale changes in nitrate concentrations and pesticide detections were evaluated for selected well networks by using the most recent sample from each well and comparing it to the results from a sample collected 7 or 11 years earlier. Because some of the NAWQA well networks provide a limited areal coverage of the aquifer system, data for raw water samples from other USGS sources and state agencies were included

    Previous studies in the forearc of the northern Chilean subduction zone have identified important tectonic features in the upper crust. As a result of these works, the West Fissure Fault System (WFFS) has recently been imaged using microseismic events. The WFFS is the westward-dipping, sharp lower boundary of the northern Chilean forearc and is geometrically opposed to subduction of the Nazca plate. The present article builds on this previous work and is novel in that it characterizes this structure's stress distribution using focal mechanisms and stress tensor analysis. The results of the stress tensor analysis show that the state of stress in the WFFS is related to its strike-slip tectonic context and likely represents a manifestation of local forces associated with the highest areas in the Andes. Two seismic clusters have also been identified; these clusters may be associated with a blind branch of the WFFS. We studied these clusters in order to determine their sources and possible connection with fluid migration across the upper plate. We observed that the two clusters differ from one another in some regards. The central cluster has characteristics consistent with an earthquake swarm with two clearly identifiable phases. Conversely, the SW cluster has a clear main shock associated with it, and it can be separated into two subclusters (A and A΄). In contrast, similarities among the two clusters suggest that the clusters may have a common origin. The b-values for both clusters are characteristic of tectonic plate boundaries. The spatial spreading, which is approximately confined to one plane, reflects progressive growth of the main fracture underlying the swarm and subcluster A. We also find that earthquakes themselves trigger aftershocks near the borders of their rupture areas. In addition, the spatio-temporal migration of hypocentres, as well as their spatial correlation with areas that are interpreted to be fluid migration zones, suggest that there is a close

    Implementation of an order by the International Joint Commission in January 2000 has changed operating procedures for dams that regulate two large reservoirs in Voyageurs National Park in northern Minnesota. These new procedures were expected to restore a more natural water regime and affect water levels, water quality, and trophic status. Results of laboratory analyses and field measurements of chemical and physical properties from May 2001 through September 2003 were compared to similar data collected prior to the change in operating procedures. Rank sum tests showed significant decreases in chlorophyll-a concentrations and trophic state indices for Kabetogama Lake (p=0.021) and Black Bay (p=0.007). There were no significant decreases in total phosphorus concentration, however, perhaps due to internal cycling of phosphorus. No sites had significant trends in seasonal total phosphorus concentrations, with the exception of May samples from Sand Point Lake, which had a significant decreasing trend (tau=-0.056, probability=0.03). May chlorophyll-a concentrations for Kabetogama Lake showed a significant decreasing trend (tau=-0.42, probability=0.05). Based on mean chlorophyll trophic-state indices (2001-03), Sand Point, Namakan, and Rainy Lakes would be classified oligotrophic to mesotrophic, and Kabetogama Lake and Rainy Lake at Black Bay would be classified as mesotrophic. The classification of Sand Point, Namakan, and Rainy Lakes remain the same for data collected prior to the change in operating procedures. In contrast, the trophic classification of Kabetogama Lake and Rainy Lake at Black Bay has changed from eutrophic to mesotrophic.

    The Carboniferous sequences of the northeast flank of the Parana Basin and those of the southwest flank of the Parnaiba Basin have been the subject of discussion and polemics for quite a long time, especially in terms of their stratigraphic relations and depositional environments. Thus, we reinforce our main objective, which is to furnish data for the definition of the uranium potential in these Carboniferous sediments, by adding recently acquired information that should aid in the clarification of the existing controversies. The Carboniferous along the northeast flank of the Parana Basin is represented by the Aquidauana Formation which has been informally divided into three members: lower, middle and upper members. The middle member, of marine origin, constitutes a prospective target for uranium and phosphate associations, in which sandstones interbedded with shales constitute the host rocks. On the other hand, the Carboniferous of the southwest margin of the Parnaiba Basin, which encompasses the Longa, Poti and Piaui Formations has shown very remote possibilities of uranium occurrences. The regional structural framework, as reflected by the Carboniferous rocks along both basin flanks, is characterized by homoclines cut by gravity faults. The faults along these weakness zones were occasionally intruded by basic rocks of Cretaceous age. Superimposed on the regional structure, open folds appear in the form of anticlines and domes. These folds are discontinuous structures resulting from uplift due to vertical stresses or result from differential subsidence along the limbs of the folds. (Author) [pt

    2007-01-01

    More than 800 wells in the glacial aquifer system of the Northern United States were sampled for arsenic as part of U.S. Geological Survey National Water-Quality Assessment (NAWQA) studies during 1991-2003. Elevated arsenic concentrations (greater than or equal to 10 micrograms per liter) were detected in 9 percent of samples. Elevated arsenic concentrations were associated with strongly reducing conditions. Of the samples classified as iron reducing or sulfate reducing, arsenic concentrations were elevated in 19 percent. Of the methanogenic samples, arsenic concentrations were elevated in 45 percent. In contrast, concentrations of arsenic were elevated in only 1 percent of oxic samples. Arsenic concentrations were also related to ground-water age. Elevated arsenic concentrations were detected in 34 percent of old waters (recharged before 1953) as compared to 4 percent of young waters (recharged since 1953). For samples classified as both old and methanogenic, elevated arsenic concentrations were detected in 62 percent of samples, as compared to 1 percent for samples classified as young and oxic. Arsenic concentrations were also correlated with well depth and concentrations of several chemical constituents, including (1) constituents linked to redox processes and (2) anions or oxyanions that sorb to iron oxides. Observations from the glacial aquifer system are consistent with the idea that the predominant source of arsenic is iron oxides and the predominant mechanism for releasing arsenic to the ground water is reductive desorption or reductive dissolution. Arsenic is also released from iron oxides under oxic conditions, but on a more limited basis and at lower concentrations. Logistic regression was used to investigate the relative significance of redox, ground-water age, depth, and other water-quality constituents as indicators of elevated arsenic concentrations in the glacial aquifer system. The single variable that explained the greatest amount of variation in

    Bird populations are influenced by many environmental factors at both large and small scales. Our study evaluated the influences of regional climate and land-use variables on the Northern Harrier (Circus cyaneus), Black Tern (Childonias niger), and Marsh Wren (Cistothorus palustris) in the prairie potholes of the upper Midwest of the United States. These species were chosen because their diverse habitat preference represent the spectrum of habitat conditions present in the Prairie Potholes, ranging from open prairies to dense cattail marshes. We evaluated land-use covariates at three logarithmic spatial scales (1,000 ha, 10,000 ha, and 100,000 ha) and constructed models a priori using information from published habitat associations and climatic influences. The strongest influences on the abundance of each of the three species were the percentage of wetland area across all three spatial scales and precipitation in the year preceding that when bird surveys were conducted. Even among scales ranging over three orders of magnitude the influence of spatial scale was small, as models with the same variables expressed at different scales were often in the best model subset. Examination of the effects of large-scale environmental variables on wetland birds elucidated relationships overlooked in many smaller-scale studies, such as the influences of climate and habitat variables at landscape scales. Given the spatial variation in the abundance of our focal species within the prairie potholes, our model predictions are especially useful for targeting locations, such as northeastern South Dakota and central North Dakota, where management and conservation efforts would be optimally beneficial. This modeling approach can also be applied to other species and geographic areas to focus landscape conservation efforts and subsequent small-scale studies, especially in constrained economic climates.

    Full Text Available ABSTRACT In Brazilian regions affected by the citrus sudden death disease, sweet orange cultivation depends on the use of resistant rootstocks. Rangpur lime was mainly replaced by Swingle citrumelo and Sunki mandarin rootstocks, more drought-sensitive ones. The diversification of scion selections is also desirable aiming at the increasing demand for not from concentrate orange juice (NFC that requires high-quality fruits. In this work, we evaluated the performance of 6 selections of Valencia (IAC, Dom João, Late Burjasot IVIA 35-2, Rhode Red SRA 360, Temprana IVIA 25 and Campbell and Natal IAC sweet oranges grafted onto Swingle citrumelo and Sunki mandarin. The planting occurred in 2001 under rain-fed cultivation in Bebedouro, northern São Paulo state, Brazil. The outline was made through randomized blocks in a 7 × 2 factorial design (selections × rootstock, with 4 replications and 2 trees in unit. Both rootstocks performed well in the region. Sunki mandarin rootstock induced greater tree size and production per plant to the scion selections, 38 and 21%, respectively, plus higher precocity of production compared to Swingle citrumelo. The later determined a greater productive efficiency, as well as a greater percentage of juice in general, albeit with lower concentrations of soluble solids and acidity. Natal IAC, Valencia IAC and Rhode Red Valencia selections presented a higher accumulated production, on average, 218.6 kg∙plant−1 (2004 – 2008, and a higher productive efficiency (kg fruit∙m−3 of canopy due to their smaller tree size. All assessed selections produced fruits with high soluble solids content that were suitable for juice processing.

    The Taciba and Rio Bonito ('lower' Triunfo Mbr) formations are divided into six depositional sequences based on cores, gamma-ray and electrical logs from shallow drillings from northern Santa Catarina State, Brazil. Each sequence is formed by two systems tracts, a lower one, sandy (low stand) and an upper one, shaly (high stand). The Taciba Formation has three sequences, S{sub 0} to S{sub 2}; sequence S{sub 0} has a thick turbidite sandstone at the base (Rio Segredo Member) that pinches out towards the eastern margin and even disappears in the Mafra outcrop area. Sequence S{sub 1} varies from a thin fluvial-estuarine system to a thick turbidite sandstone of a channelled fan system; S{sub 1} upper shaly system tract is marine in well PP-11, and it is glacially influenced in well PP-10. Sequence S{sub 2} is a thick sandstone body of shallow marine origin, but restricted to one well (PP-11); its upper shaly tract is dominated by massive siltstones intercalated with thin, distal tempestites. The 'lower' Triunfo Member (or 'Taciba- Triunfo transition') begins with the arrival of deltaic clastics of sequence S{sub 3} lower tract, coarsening-up from medial- to proximal delta front sandstones. Sequence S{sub 4} is quite similar to S{sub 3}, both showing sandstone pro gradation from north to south, as opposed to the southwest-sourced transgressive diamictites. Sequence S{sub 5} consists of fluvial deposits at well PP-12, and two transgressive cycles from wells PP-11 to PP-9, each one of them composed of fluvial-estuarine to marine systems. Well PP-10 is an exception, where the lower cycle presents de glaciation to marine deposits. (author)

    The impact of heterogeneous reactions on the chemical components and mixing state of dust particles are investigated by observations and an air quality model over northern China between March 27, 2015 and April 2, 2015. Synergetic observations were conducted using a polarization optical particle counter (POPC), a depolarized two-wavelength Lidar and filter samples in Beijing. During this period, dust plume passed through Beijing on March 28, and flew back on March 29 because of synoptic weather changes. Mineral dust mixed with anthropogenic pollutants was simulated using the Nested Air Quality Prediction Modeling System (NAQPMS) to examine the role of heterogeneous processes on the dust. A comparison of observations shows that the NAQPMS successfully reproduces the time series of the vertical profile, particulate matter concentration, and chemical components of fine mode (diameter ≤ 2.5 μm) and coarse mode (2.5 μm reactions, the simulated nitrate, ammonium, and sulfate are in better agreement with the observed values during this period. The modeling results with observations show that heterogeneous reactions are the major mechanisms producing nitrate reaching 19 μg/m3, and sulfate reaching 7 μg/m3, on coarse mode dust particles, which were almost 100% of the coarse mode nitrate and sulfate. The heterogeneous reactions are also important for fine mode secondary aerosols, for producing 17% of nitrate and 11% of sulfate on fine mode dust particles, with maximum mass concentrations of 6 μg/m3 and 4 μg/m3. In contrast, due to uptake of acid gases (e.g. HNO3 and SO2) by dust particles, the fine mode anthropogenic ammonium nitrate and ammonium sulfate decreased. As a result, the total fine mode nitrate decreased with a maximum of 14 μg/m3, while the total fine mode sulfate increased with a maximum of 2 μg/m3. Because of heterogeneous reactions, 15% of fine mode secondary inorganic aerosols and the entire coarse mode nitrate and sulfate were internally mixed with

    This aim of work is the geological and geochronological study of rocks cropping out on Cardoso Island, on the southeastern coast of Sao Paulo States, close to be boundary with Parana State. The Island with an area of about 151 km 2 is a protected area administered by the Forest Institute of Environment Secretariat of the State of Sao Paulo. It is mountanious, with a peak at 814 m, and is covered by dense Mata Atlantica vegetation. The terrains which compose the island are mainly an igneous complex with light grey leucocratic, inequigranular, medium - to coarse-grained syenites. The predominant Tres Irmaos Syenite (STI), composed of pyroxene, hornblende, and perthitic to mesoperthitic microcline, has a magmatic flow structures, and is cut by the Cambriu alkali-feldspar Granites (GC), which is pinkish grey, leucocratic and medium-grained. Geochemical analysis of STI and GC demonstrate their meta luminous alkaline nature and late-orogenic to an orogenic character. The geochronological results suggest that the bodies were formed between 620 and 570 My according to the U-Pb method in zircons, with cooling between 597 and 531 My (K-Ar in amphiboles). Whole rock Sm-Nd analysis yield T DM ages in the Meso and Paleoproterozoic (1.200 - 2.200 My). belt of low grade meta sedimentary rocks occurs in the northern part of the island. Quartz schist, quartz-mica schist and mica-quartz schist, often containing andaluzite and cordierite, predominate. The geochemical and geochronological data suggest that the sources of the metasediments were andesites of continental arc whose protolities separated from the mantle during the Paleoproterozoic, between 1.800 and 2.200 My. These metasediments probably continue on the continent in the Taquari region and extend southwards in narrow strips between the granitoids of the Paranagua Domain. Although quaternary deposits are expressive, they were not studied in details since they were not the objectives of this study. (author)

A greater knowledge about parasite control in the field is necessary to establish control strategies closer to farmer's reality and easier to be performed. This study characterized the practices adopted for controlling such ectoparasites on 23 cattle ranches from the Triângulo Mineiro and Alto Paranaíba region in the state of Minas Gerais, through interviews. Most interviewees recognized the importance of these parasites to livestock, however, many problems related to parasite control were observed. Control of horn flies and cattle tick was a routine in 17.4% and 95.7% of the ranches, respectively, triggered by high infestations on animals. More than six insecticide/acaricide treatments were applied yearly in all cattle ranches controlling horn flies and in 76.5% of the ranches controlling the cattle tick. Pesticide products were applied mostly by manual backpack sprayers (63.6% without restraining the animals in 45.5% of ranches. Product dilution following manufacturer's recommendations was performed by 45.5% of interviewees, but 63.6% of them used lower doses per animal than technically recommended. Associations of organophosphates and pyrethroids were the main products used to control both parasites. Although pesticide use was a routine practice, the use of personal protective equipment (PPE was not common among surveyed people. Most interviewees were able to recognize epidemiological characteristics of the parasites; however, parasite control measures adopted at most cattle ranches tend to jeopardize the efficacy of products, susceptibility of parasites and sustainability of control programs.

    The Bolivia-Brazil Natural Gas Pipeline - GASBOL - begins in the city of Santa Cruz of La Sierra, in Bolivia, arriving in Canoas (RS), in Brazil, traveling an extension of 3.150 Km. Of this total, 2.593 Km are in Brazilian soil. In the kilometer 526+500m of the south spread, GASBOL crosses the reservoir of the Vocoroca's dam (COPEL), which had its operational level reduced, in face of the station of the droughts that usually reaches the area in the months of March to September. The lowing of the reservoir caused the turn of the course of Fojo River (Sao Joaozinho River) to its natural quota, forming a waterfall, whose hydraulic gradient caused the removal of the sediment and part of the foundation soil, discovering the pipe that was with space free from approximately 13 m of length. This paper discusses the solution adopted, as well as the several details of the recovery project, besides geotechnical and hydraulic studies and the aspects of safety of the Gas Pipeline. (author)

    concentrations. Strontium and barium were the most frequently detected and usually were present in the highest concentrations. Iron and manganese were the next most commonly detected and next highest in concentrations. Iron concentrations were the most variable with respect to the range of variations (both within local networks and aquifer-wide) and with respect to the disparity between magnitude of concentrations (detections) and the frequency of samples below reporting limits (nondetections). Antimony, beryllium, cadmium, silver, and thallium were detected too infrequently for substantial interpretation of their occurrence or distributions or potential human-health implications. For those elements that were more frequently detected, there are some geographic patterns in their occurrence that primarily reflect climate effects. The highest concentrations of several elements were found in the West-Central glacial framework area (High Plains and northern Plains areas). There are few important patterns for any element in relation to land use, well type, or network type. Shallow land-use (monitor) wells had iron concentrations generally lower than the glacial aquifer system wells overall and much lower than major-aquifer survey wells, which comprise mostly private- and public-supply wells. Unlike those for iron, concentration patterns for manganese were similar among shallow land-use wells and major-aquifer survey wells. An apparent relation between low pH and relatively low concentrations of many elements, except lead, may be more indicative of the relatively low dissolved-solids content in wells in the Northeastern United States that comprise the majority of low pH wells, than of a pH dependent pattern. Iron and manganese have higher concentrations and larger ranges of concentrations especially under more reducing conditions. Dissolved oxygen and well depth were related to iron and manganese concentrations. Redox conditions also affect several trace elements such

    Full Text Available AIM: We present an update on the composition of the fish species of the Restinga de Jurubatiba National Park and the Imboassica Lagoon, in the northern portion of Rio de Janeiro State, based on collecting efforts of almost two decades, historical museum records, and a review of the literature. METHODS: Specimens were collected using a variety of techniques, mostly between 1994 and 2012, and were fixed with the use of a 10% solution of formalin and subsequently stored in 70% alcohol solution. All specimens examined are deposited in the fish collections of the Núcleo em Ecologia e Desenvolvimento Socioambiental de Macaé, Universidade Federal do Rio de Janeiro (NPM, and Museu Nacional, Universidade Federal do Rio de Janeiro (MNRJ. Continental (freshwater fishes and some marine or estuarine species frequently collected were regarded as Resident, whereas marine species collected only sporadically were regarded as Occasional. Possible associations between the orientation of the lagoons and the composition of Resident fishes were explored through a Correspondence Analysis (CA. RESULTS: A total of 100 species, belonging to 19 orders and 41 families of the Teleostei were recorded. When both Resident and Occasional species are considered, families Carangidae and Engraulidae, with nine and eight species respectively, are the most representative. When only Resident species are considered, the Gerreidae and Gobiidae, both with seven species, are the most representative families. The Imboassica Lagoon, with 76 species, has the highest species richness among lagoons included in this study. A total of 81 species were recorded in the Restinga de Jurubatiba National Park, a number two times higher than reported on previous studies. An identification key, including 57 Resident species, is also presented. CONCLUSIONS: Parallel lagoons were characterized by a small group of continental species presumably of marine ancestry (Secondary Division, while marine species

    Pedogenic and non-pedogenic calcrete facies are very common feature of Marilia (Brazil) and Mercedes (Uruguay) formations in the Parana Basin. The non-pedogenic ones constitute massive limestone facies that have been recently interpreted as groundwater calcretes. These limestones are exploited in both countries to supply raw materials to Portland cement and soil conditioner in origin and age of calcretization phenomena. In Uruguay, the calcretization process seens to be band formation. Field relationships and fossil assemblage point to a Paleocene (or later) age for the calcretization. In Brazilian territory, the groundwater calcretes aresupposed to be of Upper Cretaceous age due to the presence of dinosaurs scattered through the Bauru Group, including siliciclastic beds below and above the calcretes. The authors assume that calcretization processes are similar in both countries (host rocks, intensity, size, textures, geometries and economic potential). The main difference is in age of the calcretization. (author)

    Alkali-bearing Ti oxides were identified in mantle xenoliths enclosed in kimberlite-like rocks from Limeira 1 alkaline intrusion from the Alto Paranaíba Igneous Province, southeastern Brazil. The metasomatic mineral assemblages include mathiasite-loveringite and priderite associated with clinopyroxene, phlogopite, ilmenite and rutile. Mathiasite-loveringite (55-60 wt.% TiO2; 5.2-6.7 wt.% ZrO2) occurs in peridotite xenoliths rimming chromite (˜50 wt.% Cr2O3) and subordinate ilmenite (12-13.4 wt.% MgO) in double reaction rim coronas. Priderite (Ba/(K+Ba)textures and chemical zoning of associated minerals suggest that the metasomatic reactions responsible for the formation of the alkali-bearing Ti oxides took place shortly prior the entrainment of the xenoliths in the host magma, and is not connected to old (Proterozoic) mantle enrichment events.

    Full Text Available The morphological features of the relief and its quantitative morphometric quantification are essential elements in interpreting its influence on the hydrogeomorphological dynamics of watersheds in mountainous environments. This is particularly important when studying small spatial units (micro watersheds and torrential regimes, as this influences the sudden and aggressive hydrological responses of these systems and the likelihood of activation of mass removal processes. In the study region (Vargas State, Venezuela the most important debris flow recorded in Venezuela’s history occurred on December 14, 15 and 16, 1999, as a consequence of extremely heavy rainfall in those dates associated with a very particular weather. For the above reasons, this research conducted a quantitative analysis of the relief features in watersheds of “El Ávila” massive northern hillside and their impact on the local hydrogeomorphological dynamics, aimed at identifying the main attributes influencing these dynamics. The study area is located in the northern-central region of Venezuela, in the central part of Vargas state, delimited by 10º32’25”-10º37’35”N and 66º40’08”- 66º59’12”W, and comprises thirteen micro watersheds of mountainous environment. The methodology consisted of (a the geomorphological characterization of the area, from the review and interpretation of digitized base maps at scales 1:5 000 and 1:25 000, the digital elevation model (DEM, aerial photographs at scale 1:5 000, orthophotomaps at scale 1:25 000, satellite images, Google Earth and Google Maps images, and geomorphological maps (landforms and geomorphological processes at scale 1:25 000; (b measurements and calculations of basic morphometric parameters of watershed relief on digital mapping using the ArcGIS 9.2 and their Spatial Analysis and ArcHydro modules, and the mathematical equations that define the other parameters using MS Excel; (c descriptive statistical

    Full Text Available This work evaluates the lesions caused by ectoparasites like Boophilus microplus, Dermatobia hominis, Haematobia irritans in cattle leather, in tanning industry. Such material came from the Northwest of Parana State and Southwest of Mato Grosso State. The evaluation of leather occured in August, 1999 and February, 2000. In August, 1999, 15,530 samples from Northwest of Parana State and 11, 289 samples from the Southwest of Mato Grosso State were analysed. The result obtained showed that the main damage was caused by ticks bites, representing 63% in Parana and 67% in Mato Grosso of cattle leather infected by tick. It was followed by D. hominis (Tropical warble infection, where 34% of the cattle in Parana and 19% in Mato Grosso showed larvae infection and 3% in Parana and 14%> of the remaining cattle presented lesions by horn fly. In February, 2000 9,690 samples from Northwest of Parana State and 16,271 samples from the Southwest of Mato Grosso State were analyzed. Again the highest incidence of damage was caused by the ticks where 60% of cattle leather in Paranaand 65% in Mato Grosso were infected. It was also followed by tropical warble infection, where 35,5% of cattle in Parana and 20% in Mato Grosso presented larvae infection and 4,5% in Parana and 15% of the remaining cattle showed lesions by horn fly. Although tick caused greater leather lesions, the larvae ofD. hominis was responsible for the low quality of the material because such damage is irreversible. The Parana obtained the lowest score for leather due to the high incidence of larvae od D. hominis.Este trabalho avalia as lesões causadas pelos ectoparasitas Boophilus microplus, Dermatobia hominis, Haematobia irritans no couro de bovinos procedentes da região Noroeste do Estado do Paraná e Sudoeste do Estado do Mato Grosso, nos meses de agosto de 1999 e fevereiro de 2000.

    1998-07-01

    This aim of work is the geological and geochronological study of rocks cropping out on Cardoso Island, on the southeastern coast of Sao Paulo States, close to be boundary with Parana State. The Island with an area of about 151 km{sup 2} is a protected area administered by the Forest Institute of Environment Secretariat of the State of Sao Paulo. It is mountanious, with a peak at 814 m, and is covered by dense Mata Atlantica vegetation. The terrains which compose the island are mainly an igneous complex with light grey leucocratic, inequigranular, medium - to coarse-grained syenites. The predominant Tres Irmaos Syenite (STI), composed of pyroxene, hornblende, and perthitic to mesoperthitic microcline, has a magmatic flow structures, and is cut by the Cambriu alkali-feldspar Granites (GC), which is pinkish grey, leucocratic and medium-grained. Geochemical analysis of STI and GC demonstrate their meta luminous alkaline nature and late-orogenic to an orogenic character. The geochronological results suggest that the bodies were formed between 620 and 570 My according to the U-Pb method in zircons, with cooling between 597 and 531 My (K-Ar in amphiboles). Whole rock Sm-Nd analysis yield T{sub DM} ages in the Meso and Paleoproterozoic (1.200 - 2.200 My). belt of low grade meta sedimentary rocks occurs in the northern part of the island. Quartz schist, quartz-mica schist and mica-quartz schist, often containing andaluzite and cordierite, predominate. The geochemical and geochronological data suggest that the sources of the metasediments were andesites of continental arc whose protolities separated from the mantle during the Paleoproterozoic, between 1.800 and 2.200 My. These metasediments probably continue on the continent in the Taquari region and extend southwards in narrow strips between the granitoids of the Paranagua Domain. Although quaternary deposits are expressive, they were not studied in details since they were not the objectives of this study. (author)

    The 'Luz do Campo' program has created positive and favorable impact to the opening of opportunities in the rural area. It has contributed to facilitate the access of workers to energetic facilities and has contributed to providing them with better social and economical conditions. As a consequence after the accomplishment of the rural electrification process in the settlements of 'Anhumas' and 'Maria Neto' implanted in Ribeirao Claro in Parana, it was possible to come to terms with two projects of Sericiculture in that location. The energy consumption of these projects has not been only restricted to human comfort, but has also been aimed at the production. As a result, the economical success achieved in those settlements in less than a year's time, is due to the transformation actions in the countryside that have lowered poverty and raised the perspectives of better life quality to the settlers.

    Full Text Available ABSTRACT: The aim of this study was to identify the strategic direction of agroprocessing enterprises and the level of compliance with consumer requirements, as well as the position of agro-industry enterprises in relation to their primary competitors. To this end, a survey was performed, which included nine family agro-industry enterprises from the Northern region of Rio Grande do Sul (RS and their respective buyers. For this research, the Importance-Performance Matrix methodology described by SLACK (2002 was used. The strategy of the analyzed agro-industry enterprises relies on differentiation, presenting most of the items studied in accordance with consumers’ demands. Consequently, they are not at a disadvantage to their competitors in most criteria that consumers consider fundamental at the time of purchase.

  10. Ordovician of the Sauk megasequence in the Ozark region of northern Arkansas and parts of Missouri and adjacent states: Chapter 11

    Exposures of Ordovician rocks of the Sauk megasequence in Missouri and northern Arkansas comprise Ibexian and lower Whiterockian carbonates with interspersed sandstones. Subjacent Cambrian strata are exposed in Missouri but confined to the subsurface in Arkansas. The Sauk-Tippecanoe boundary in this region is at the base of the St. Peter Sandstone. Ulrich and associates divided the Arkansas section into formations early in the 20th century, principally based on sparse collections of fossil invertebrates. In contrast, the distribution of invertebrate faunas and modern studies of conodonts will be emphasized throughout this chapter. Early workers considered many of the stratigraphic units to be separated by unconformities, but modern analysis calls into question the unconformable nature of some of their boundaries. The physical similarity of the several dolomites and sandstones, complex facies relations, and lack of continuous exposures make identification of individual formations difficult in isolated outcrops.

  14. Inventory and state of activity of rockglaciers in the Ile and Kungöy Ranges of Northern Tien Shan from satellite SAR interferometry

    The best visual expression of mountain permafrost are rockglaciers, which, in contrast to the permafrost itself, can be mapped and monitored directly using remotely sensed data. Studies carried out in various parts of the European Alps have shown surface acceleration of rockglaciers and even destabilization of several such landforms over the two last decades, potentially related to the changing permafrost creep conditions. Changes in rockglacier motion are therefore believed to be the most indicative short- to medium-term response of rockglaciers to environmental changes and thus an indicator of mountain permafrost conditions in general. The ESA DUE GlobPermafrost project develops, validates and implements EO products to support research communities and international organizations in their work on better understanding permafrost characteristics and dynamics. Within this project we are building up a worldwide long-term monitoring network of active rockglacier motion investigated using remote sensing techniques. All sites are analysed through a uniform set of data and methods, and results are thus comparable. In order to quantify the rate of movement and the relative changes over time we consider two remote sensing methods: (i) matching of repeat optical data and (ii) satellite radar interferometry. In this contribution, we focus on the potential of recent high spatial resolution SAR data for the analysis of periglacial processes in mountain environments with special attention to the Ile and Kungöy Ranges of Northern Tien Shan at the border between Kazakhstan and Kyrgyzstan, an area which contains a high number of large and comparably fast (> 1m/yr) rockglaciers and is of interest as dry-season water resource and source of natural hazards. As demonstrated in the past with investigations conducted in the Swiss Alps, the visual analysis of differential SAR interferograms can be employed for the rough estimation of the surface deformation rates of rockglaciers and

  15. Prey-capture efficiency between juveniles and adults, feeding habitat and abundance of Wattled Jacana foragers in northern Pantanal, Mato Grosso state, Brazil

    LR Forti

    Full Text Available The choice of foraging strategies implies an attempt at gaining energy by predators. Supposedly, the difference in employing the "sit and wait" or "active foraging" behavior lays in hunter skills, experience and the kind of prey consumed. With the hypothesis that "active foraging" demands no learning, in this study we compared the prey capture efficiency among Wattled Jacana juveniles and adults, and also present descriptive information about feeding habitat and the abundance variation of foragers throughout the day in the northern Pantanal. Prey capture efficiency did not differ significantly among juveniles and adults, corroborating our initial hypothesis that "active foraging" is an instinctive behavior and demands no experience to be effective. However, future work is necessary to compare the energetic quality of consumed items by juveniles and adults, searching for differences explained by adults' experience. Foraging individuals were found at an average distance of 14 m ranging from 2 to 42 m from the margin of the sampled swamps, however 64% of the foragers were found closer to the margins. The average depth of foraging sites was 17 cm, ranging from 5 to 40 cm, although no preference for specific classes of depth was found (p > 0,05. Despite the accepted general pattern of birds being more active in the early morning, the largest number of individuals foraging was observed between 11:00 and 12:00 AM, but no significant difference was found in the abundance of foraging individuals among different periods of the day. Factors, which were not analyzed, such as food availability and presence of competitors and predators need to be studied to reveal the main factors of the spatial and temporal distribution of the Wattled Jacana.

    Previous research has focused exclusively on weight loss or weight maintenance following weight loss, i.e. secondary weight maintenance (SWM). The long-term results of SWM have been modest, suggesting that preventing initial weight gain among normal weight or overweight individuals, i.e. primary weight maintenance (PWM), may be more successful. The aim of this study was to compare the pattern of weight change between Swedish and US women and to contrast eating and physical activity between the two countries. A questionnaire of attitudes, strategies and behaviours regarding physical activity, food habits, body image and demands to maintain weight was mailed to 4021 Swedish and 3199 US individuals. Subjects had weight measurements taken 10 years apart in the Västerbotten Intervention Programme in northern Sweden, and self-reported weight as part of the Upstate Health and Wellness Study in Upstate New York. The mean 10-year percent weight change, and weight change in kilograms, were calculated between the two countries for nine female age (30, 40, 50 years at baseline) by BMI (20-25, 25-30, 30-35) groups. For the Swedish/US pair showing the largest differences in these two endpoints, analysis of variance, correlations and chi-square tests identified likely contributors to the observed differences in weight change. For all subgroups combined, the mean percent weight changes for Swedish women and US women were 4.9% (SD = 5.8) and 9.1% (SD = 13.7) respectively (pweight change between the two countries were largest among normal weight 30 year olds. Eight variables were identified as likely contributors to this difference. A significantly higher proportion of Swedish women selected the healthy alternatives for these eight variables. Percent weight change varied considerably over healthy versus unhealthy response levels in the US, but not in Sweden. The prevalence of obesity among the Swedish women did not progress as rapidly as among the US. The greatest weight gain

  1. Relative impact of previous disturbance history on the likelihood of additional disturbance in the Northern United States Forest Service USFS Region

    2015-12-01

    The Landsat archive is increasingly being used to detect trends in the occurrence of forest disturbance. Beyond information about the amount of area affected, forest managers need to know if and how disturbance regimes change. The National Forest System (NFS) has developed a comprehensive plan for carbon monitoring that requires a detailed temporal mapping of forest disturbances across 75 million hectares. A long-term annual time series that shows the timing, extent, and type of disturbance beginning in 1990 and ending in 2011 has been prepared for several USFS Regions, including the Northern Region. Our mapping starts with an automated detection of annual disturbances using a time series of historical Landsat imagery. Automated detections are meticulously inspected, corrected and labeled using various USFS ancillary datasets. The resulting maps of verified disturbance show the timing and types are fires, harvests, insect activity, disease, and abiotic (wind, drought, avalanche) damage. Also, the magnitude of each change event is modeled in terms of the proportion of canopy cover lost. The sequence of disturbances for every pixel since 1990 has been consistently mapped and is available across the entirety of NFS. Our datasets contain sufficient information to describe the frequency of stand replacement, as well as how often disturbance results in only a partial loss of canopy. This information provides empirical insight into how an initial disturbance may predispose a stand to further disturbance, and it also show a climatic signal in the occurrence of processes such as fire and insect epidemics. Thus, we have the information to model the likelihood of occurrence of certain disturbances after a given event (i.e. if we have a fire in the past what does that do to the likelihood of occurrence of insects in the future). Here, we explore if previous disturbance history is a reliable predictor of additional disturbance in the future and we present results of applying

  2. Joint Inversion of Geoid Anomaly and Teleseismic P-Wave Delay Times: Modeling Density and Velocity Perturbations Beneath the Parana Magmatic Province

    Science.gov (United States)

    Chaves, C. A. M.; Ussami, N.; Ritsema, J.

    2014-12-01

    The Parana Magmatic Province (PMP) is one of the largest continental igneous provinces (LIP) on Earth. It is well dated at 133 Ma preceding the opening of the South Atlantic Ocean, but the causative geodynamic processes are still poorly understood. Although a low-velocity anomaly has been imaged by seismic tomography in the northeast region of the PMP and interpreted as a fossil conduct of a mantle plume that is related to the flood basalt eruptions, geochemical data indicate that such magmatism is caused by the melting of a heterogeneous and enriched lithospheric mantle with no deep plume participation. Models of density perturbations in the upper mantle estimated from joint inversion of geoid anomalies and P-wave delay times will offer important constraints on mantle dynamics. A new generation of accurate global geopotential models derived from satellite-missions (e.g. GRACE, GOCE) allows us to estimate density distribution within the Earth from geoid inversion. In order to obtain the residual geoid anomaly related to the density structure of the mantle, we use the EGM2008 model removing estimated geoid perturbations owing to variations in crustal structure (i.e., topographical masses, Moho depth, thickness of sediments and basalts). Using a spherical-Earth approximation, the density model space is represented by a set of tesseroids and the velocity model is parameterized in nodes of a spherical grid where cubic B-splines are utilized as an interpolation function. To constrain the density inversion, we add more than 10,000 manually picked teleseismic P-wave delay times. During the inversion procedure, density and P-wave velocity are linked through the optimization of a constant linear factor correlating density and velocity perturbation. Such optimization will be performed using a probability density function (PDF) [Tarantola, 2005]. We will present the preliminary results of this joint inversion scheme and hypothesize on the geodynamic processes responsible for

  4. Proposed amendment for Presidential Permit PP-63 and associated modifications to 500 kV international transmission line, Forbes, Minnesota to Manitoba, Canada Northern States Power Company. Final Environmental Assessment

    Energy Technology Data Exchange (ETDEWEB)

    1992-02-01

    Northern States Power Company, (NSP), a Minnesota investor owned utility has applied to the Office of Fossil Energy, United States Department of Energy, to amend Presidential Permit PP-63 to allow for alterations to the 500 kV transmission line and as sedated facilities currently regulated by this permit. The alterations proposed for the 500 kV line owned by NSP are part of a long term effort sponsored by NSP to upgrade the existing NSP transmission system to allow for increased exchange of electricity with the Manitoba Hydro-Electric Board. Presidential Permit PP-63 authorized NSP to construct, connect, operate and maintain a 500 kV line at the United States/Canadian border approximately seven-and-a-half miles west of Warroad in Roseau County, Minnesota. This line connects with a 500 kV line owned and operated by the Manitoba Hydro-Electric Board (MHEB), which extends from Dorsey, Manitoba, Canada to the United States/Canadian border. NSP proposes to increase the electricity transfer capability of this transmission facility by constructing a new 80-acre substation on the existing 500 kV line in Roseau County, Minnesota, and upgrading the existing substation at Forbes, Minnesota. The proposed Roseau substation would contain two 41.5 ohm series capacitor banks. In addition, static VAR compensators are to be installed at the existing Forbes Substation. Approximately 5 acres would be added to the 30-acre Forbes site to house the additional equipment. No new lines would enter or exit the facility. NSP proposes to place the new Roseau Substation in service in May 1993 and to complete the upgrading of the Forbes Substation in March 1994. The primary, initial purpose of these modifications is to enable NSP to import 400 megawatts of electric power from MHEB during the summer months to meet peak electrical demand in the Minneapolis-St. Paul area. It is expected that this power transfer would begin in 1993.

    The data characterizing the sanitary and epidemiological state of the population and the groups of persons, forced to quit the place of their permanent residence, on the territory embracing the Nadterechny, Naursky and Shelkovskoi regions of the Chechen Republic (CR) during the period of December 16, 1999, to February 19, 2000. A sharp deterioration of the situation which led to the renewal of hostilities on the whole territory of the CR was accompanied by the disorganization of all vitally important structures, including the systems of health service, sanitary and epidemiological surveilance. The above-mentioned regions of the CR were of great importance in the organization of sanitary-hygienic and antiepidemic measures, as it is on the territories of these regions that the camps with many thousands of persons, forced to move temporarily from Grozny and other regions affected by hostilities, are concentrated. The activity of specialized brigades of the antiepidemic service, working in cooperation with local organs of health service, the State Committee of Sanitary and Epidemiological Surveillance of the Russian Federation and local services of sanitary and epidemiological surveillance, was of great importance for the restoration of the structures and functions of sanitary and antiepidemic organs.

    Full Text Available In northeastern Brazil, most well-preserved Atlantic Rainforest fragments are situated within privately-owned lands or sugarcane properties, mainly in the states of Alagoas and Pernambuco. On the lands of São José Sugar Mill (USJ, in Igarassu (Pernambuco, there are 106 forest patches totaling 6,660ha, surrounded by sugarcane fields. The main goal of this study was to determine the species richness in five forest remnants within the USJ property. We completed 77 hours of observation and recording of bird voices, using binoculars and a tape recorder with a unidirectional microphone. A total of 184 bird species were registered, among which 15 were under risk of extinction, (e.g. Cercomacra laeta sabinoi, Pyriglena leuconota pernambucensis and Myrmeciza rufi cauda soror. Some species that were observed and collected in the same region in the 1940s, such as Ramphastos vitellinus, Pteroglossus aracari and Lipaugus vociferans, were not registered during the study period.

    During several decades the Alto Vale of Ribeira region (SP-PR) suffered under lead mining activities in the region. Although in 1996 all such activities ceased, the mining activities left behind a huge amount of environmental liabilities mainly in the hydrographic basin of Ribeira de Iguape river. In the present study the chemical characterization of bottom sediments was undertaken and the concentration of the major (Ca, Fe, K and Na), trace (As, Ba, Br, Co, Cs, Hf, Rb, Sb, Ta, Th, U, Zn) and rare earth elements (La, Ce, Eu, Nd, Sm, Lu, Tb, Yb and Sc) by instrumental neutron activation analysis (INAA) were determined. The validation of the analytical methodology was performed by means of certified reference materials analyses and Z-score criterion was used. Eight points were sampled at the Ribeira de Iguape river and its majorities from Adrianopolis (Pr) (site 01) to Registro (SP) (site 08). Granulometric analyses and textural classification were undertaken in the sediment samples. The results obtained by using INAA were compared to UCC (Upper Continental Crust) reference values. The environmental tools of Enrichment Factor (EF) and Geochemical Index (GI) were used to assess the degree of metal contamination in the sediment samples. Samples from site 5 (Betari river - Iporanga, SP) presented high values for As, Sb and Zn and greater IGeo (3.1 - 5.5) and EF (>7.0) values for these elements classifying this point as highly polluted for these elements as well as a strong anthropogenic contribution. Site 7 (Ribeira river - Eldorado, SP) was considered moderately polluted for As, Br and Sb. The high concentration levels of some metals and metalloids reflect the contribution of mining activities from the past in the region. From the results it can be seen that although mining activities no longer exist since 1996, the deleterious effects in the environment are still present and strong. (author)

In the Middle-East, breast cancer is diagnosed at a young age, and Arabic women are reported to have a low frequency of HR positive tumors. This study investigates HR and HER2 expression among Kurdish and Arabic women. Methods During 2008–2010, the Sulaimaniyah Directorate of Health records identified 514 Sulaimaniyah Kurdish women, 227 Kurdish women of other Governates, and 83 Arabic women with a first diagnosis of breast cancer. The breast cancers of 432 women had immunohistochemistry (IHC performed for estrogen and progesterone receptors (ER and PR and HER2. Age specific and age standardized incidence rates were calculated for Sulaimaniyah Kurds. Results were compared with Egypt and with United States (US SEER data. Results The median patient age was 46 years and 60.4% were  Conclusions Compared to the US, low age standardized and age specific breast cancer incidence rates were found in Kurdish women; nevertheless, the proportional expression of HR and HER2 for both Kurds and Arabs was comparable to that of US white women. The great majority of the breast cancer was ER+/HER2- and should respond to anti-estrogen therapy.

    In the 80's, Leonardi treated the presence of a vertebrate ichnological locality from the Barremian Corda Formation, Parnaíba Basin, on the left bank of the Tocantins river, near of the São Domingos town, Itaguatins, State of Tocantins, Brazil. Originally, the record was composed of at least seven in situ trackways, accounting for fifty six tracks. Since 2011, the Hydroelectric Power Plant do Estreito has begun to work, causing the development of a water reservoir 160 km upstream to the ichnological site, causing periodic and highly energetic floods over the footprints-bearing level and altering it. The imprints are poorly to moderate preserved, but it is possible to distinguish the general morphology and the spatial arrangement of the footprints. The specimens are represented by pes imprints, mostly circular to subcircular, with no digital and claw impressions. No distinguishable manus imprints are present. The trackways are relative narrow with respect to the size of the tracks, so they are considered into the Parabrontopodus-like category. The São Domingos tracks have been originally assigned to iguanodontid dinosaurs, and posteriorly related to a sauropodian origin. This idea is herein accepted, particularly to a basal sauropod, basal macronarians, or diplodocoids. Up to date, the tracks from the São Domingos locality are the only vertebrate fossil record from the Corda Formation, meaning an important contribution to the Cretaceous ichnofauna from South America.

    Landsat-8's high spatial resolution ( 30 nm nominal), improved signal-to-noise (12bit digitizer) and expanded band set open up new applications for coastal and in-land waters. We use a recent ocean color processor for Landsat-8 created by Vanhellemont and Ruddick (RSE, 2015)to examine changes in the Northern San Francisco Bay, in particular looking for possiblechanges due to the on-going California drought. For instance, a temporary drought barrier to prevent salt water intrusion was placed during May of 2015 at West False River in the Sacramento-San Joaquin Delta. Using the new Landsat-8 ocean color products, we illustrate how to monitor changes in macro algae and plants (Sago pondweed (native), Curly pondweed (non-native)) in regions directly effected,such as the Franks Track region. Product maps using panchromatic enhancement ( 15 m resolution) andscene based atmospheric correction allow a detailed synoptic look every 16 days during theSpring, Summer, and Fall of 2015. This work is part of a larger NASA funded project aimed atimproving the modeling and predictive capabilities of the biogeochemical state for the San Francisco Bay(Davis, PI: Impacts of Population Growth on the San Francisco Bay and Delta Ecosystem, 2014-2017).

    Full Text Available Patterns of spatio-temporal distribution of Brachyura are determined by the interaction among life history traits, inter and intraspecific relationships, as well as by the variation of abiotic factors. This study aimed to characterize patterns of spatio-temporal distribution of Persephona lichtensteinii, Persephona mediterranea and Persephona punctata in two regions of the northern coast of São Paulo State, southeastern region of Brazil. Collections were done monthly from July 2001 to June 2003 in Caraguatatuba and Ubatuba, using a shrimp fishery boat equipped with double-rig nets. The patterns of species distribution were tested by means of redundancy analysis (RDA and generalized linear mixed models (GLMM in relation to the recorded environmental factors (BT: bottom temperature, BS: bottom salinity, OM: organic matter and granulometry (Phi. The most influent environmental factor over the species distribution was the Phi, and the ascendant order of influence was P. lichtensteinii, P. punctata and P. mediterranea. The greater abundance of P. mediterranea showed a conservative pattern of distribution for the genus in the sampled region. The greater occurrence of P. punctata and P. lichtensteinii, in distinct transects than those occupied by P. mediterranea, seems to be a strategy to avoid competition among congeneric species, which is related to the substratum specificity.

Um maior conhecimento das práticas adotadas no combate destes parasitos faz-se necessário para que se possam estruturar estratégias de controle mais próximas da realidade do produtor rural e mais fáceis de serem executadas. Este estudo caracterizou, através de entrevistas, as práticas adotadas no controle desses ectoparasitos em 23 propriedades da mesorregião do Triângulo Mineiro e Alto Paranaíba, Minas Gerais. A maioria dos entrevistados reconheceu a importância desses parasitos para a atividade pecuária, entretanto, diversos problemas relativos ao controle parasitário foram observados. O controle da mosca-dos-chifres e do carrapato-do-boi era uma prática rotineira em, respectivamente, 17,4% e 95,7% das propriedades, geralmente realizado em função de elevado grau de infestação dos animais. Mais de seis aplicações de ectoparasiticidas eram realizadas por ano em todas as propriedades que empregavam tratamentos para o controle da mosca e em 76,5% daquelas que combatiam o carrapato. Os produtos eram aplicados principalmente com bombas costais manuais (63,6% e sem a contenção dos animais em 45,5% das propriedades. A diluição dos produtos segundo recomendações dos fabricantes era realizada por 45,4% dos entrevistados, porém, 63,6% aplicavam um volume de solução por animal menor do que o tecnicamente recomendado.

  7. Northern Ireland: an anomaly.

    Science.gov (United States)

    Simpson, A

    1989-01-01

    The British Abortion Act of 1967, which makes abortion legal up to 28 weeks, does not extend to Northern Ireland, where abortion is still regulated by the 1861 Offences Against the Person Act, which makes abortion a felony, and the 1929 Infant Life Preservation Act, which prohibits abortion after the 28th week of pregnancy. The Bourne Judgment of 1928, in which a court held in favor of one Dr. Alex Bourne, who performed an early abortion, may be cited as precedent, but not as law. A woman in Northern Ireland may have an abortion only on the National Health Service and only if pregnancy is life-threatening, if she is mentally retarded, or if the child is likely to be abnormal. How many abortions are actually performed in Northern Ireland each year is not known. Essentially, women with unwanted pregnancies have only 3 options: to have the baby, to risk a back street abortion, and to go to England. Since 1967, 20,000 Northern Irish women have had abortions in England, but it is a privilege reserved for the wealthy because the woman must bear the expenses of traveling to England, establishing residency there, and paying hospital fees. All of this takes time and results in many women having late abortions. The women also must bear the stigma of having done something of which neither church in Northern Ireland approves. Northern Irish women, quite simply, do not have the same rights as women in England, Scotland, and Wales.

    Commercial field corn (Zea mays L.) hybrids transformed to express some or all of the lepidopteran insect-resistant traits present in SmartStax corn hybrids were evaluated for insecticidal efficacy against a wide range oflepidopteran corn pests common to the northern United States, during 2008 to 2011 at locations in 15 states. SmartStax hybrids contain a pyramid of two Bacillus thuringiensis (Bt) derived events for lepidopteran control: event TC1507 expressing Cry1F protein and MON 89034 expressing CrylA.105 + Cry2Ab2. These studies focused on characterization of the relative efficacy of each event when expressed alone or in combination, and compared with non-Bt hybrid. Corn hybrids containing pyramided insecticidal proteins Cry1F + Cry1A.105 + Cry2Ab2 (SmartStax) consistently showed reduced plant feeding damage by a wide range of lepidopteran larvae compared with single event and non-Bt hybrids. Corn hybrids expressing TC1507 or MON 89034 as single or pyramided events were consistently efficacious against Ostrinia nubilalis (Hübner). SmartStax hybrids had less injury from Agrotis ipsilon (Hufnagel) and Striacosta albicosta (Smith) than corn hybrids containing only event MON 89034 but were not more efficacious than single event TC1507 hybrids. Corn hybrids with event MON 89034 provided better control of Helicoverpa zea (Boddie), than event TC1507 alone. Spodoptera frugiperda (J.E. Smith) efficacy was higher for hybrids with pyramid events and single events compared with the non-Bt hybrids. The spectra of activity of events TC1507 and MON 89034 differed. The combination of TC1507 + MON 89034 provided redundant control of some pests where the spectra overlapped and thereby are expected to confer a resistance management benefit.

    The association between prevalence of celiac disease and geographic region is incompletely understood, but the occurrence of several autoimmune disorders has been found to vary along a North-South gradient. We examined geographic, demographic, and clinical factors associated with prevalence of celiac disease and gluten-free diet in the United States. In a population-based study, we analyzed data on gluten-related conditions from the National Health and Nutrition Examination Survey, from 2009 through 2014, on 22,277 participants 6 years and older. We identified persons with celiac disease based on results of serum tests for IgA against tissue transglutaminase and endomysium or on both a health care provider diagnosis and adherence to a gluten-free diet. Gluten avoidance without celiac disease was defined as adherence to a gluten-free diet without a diagnosis of celiac disease. We compared mean serum levels of biochemical and nutritional markers based on status of gluten-related conditions. We found 0.7% of participants to have celiac disease and 1.1% of participants to avoid gluten without celiac disease. Celiac disease was more common among individuals who lived at latitudes of 35°-39° North (odds ratio, 3.2; 95% confidence interval, 1.4-7.1) or at latitudes of 40° North or more (odds ratio, 5.4; 95% CI, 2.6-11.3) than individuals who lived at latitudes below 35° North, independent of race or ethnicity, socioeconomic status, and body mass index. Gluten avoidance without celiac disease was more common among individuals who lived at latitudes of 40° North or more, independent of demographic factors and body mass index. Participants with undiagnosed celiac disease (identified by positive results from serologic tests) had lower mean levels of vitamin B-12 and folate (data collected from 2009 through 2012) than persons without celiac disease. Participants with a health care provider diagnosis of celiac disease had a lower mean level of hemoglobin than persons

  10. Tornadoes Strike Northern Wisconsin

    2007-01-01

    A series of tornadoes ripped through the Upper Midwest region of the United States in the evening of June 7, 2007. At least five different tornadoes touched down in Wisconsin, according to the Associated Press, one of which tore through the Bear Paw Resort in northern Wisconsin. Despite dropping as much as fifteen centimeters (six inches) of rain in some places and baseball-size hail in others, authorities were reporting no deaths attributable to the storm system, and only a smattering of injuries, but considerable property damage in some areas. When the MODIS instrument on NASA's Terra satellite observed the area on June 9, 2007, the track torn through the woods by one of the tornadoes stands out quite clearly. This photo-like image uses data collected by MODIS in the normal human vision range to give a familiar natural-looking appearance. The landscape is largely a checkerboard of farms, towns, roads, and cities. The pale land is predominantly farmland where crops have not fully grown in yet. Dark blue shows the winding path of rivers and lakes dotting the landscape. The large blue lake on the east (right) side of the image is Lake Michigan. Towns and cities, including the city of Green Bay, are gray. To the north side, farmland gives way to dark green as land use shifts from agriculture to the Menominee Indian Reservation and Nicolet National Forest. The diagonal slash through the dark green forested land shows the tornado track. Bare land was revealed where the tornado tore down trees or stripped vegetation off the branches. The high-resolution image provided above is at MODIS' full spatial resolution (level of detail) of 250 meters per pixel. The MODIS Rapid Response System provides this image at additional resolutions.

    Full Text Available In recent decades, the northwest of the state of Paraná, Brazil, has undergone a dramatic suppression and fragmentation of its primary vegetation, currently there remains small and sparse forest fragments. From this perspective, this study aimed to do an inventory of and analyze the assembly of birds of prey (Cathartiformes, Accipitriformes, Strigiformes, and Falconiformes in the Perobas Biological Reserve, a conservation area of 8,716 ha, which represents one of the last remnants with significant extent of semideciduous seasonal forest in Paraná. The counting method by fixed sites, as well as hearing sites and playback, was used to sample the bird of prey species in the reserve, from June 2009 to January 2012, with a total sampling effort of 210 h. Altogether 25 raptor species were surveyed, a value corresponding to 37% of the species richness known for Paraná. Among the records, 3 species are worth highlighting, Spizaetus melanoleucus, Asio flammeus, and Strix virgata, listed in the current Red Book of Endangered Fauna in Paraná and poorly documented in the region. About 70% of the observed species have habits associated with forest environments, while 30% are associated with open areas, such as pastures and farmland surrounding the forest. These results reaffirm the importance of this reserve for the conservation and preservation of many bird species, especially those rare and regionally endangered.

    Infections caused by multidrug resistant microorganisms are a global health problem, and Pseudomonas aeruginosa is an important nosocomial pathogen, easily disseminated in the hospital environment. The aim of this study was to determine SPM-1 in P. aeruginosa strains in 30 Brazilian hospitals and the genetic similarity of isolates. We analyzed 161 isolates of carbapenem-resistant P. aeruginosa. Imipenem/EDTA and imipenem strip were used for phenotypic detection of MBL production; and real-time polymerase chain reaction (PCR) for genetic detection. Genetic similarity was determined by rep-PCR. We obtained 136/161 (84.5%) isolates with positive phenotypic result for metallo-β-lactamase (MBL) and the bla SPM-1 gene was identified in 41 isolates. There was a predominant profile (>95% of genetic similarity) in 92.7% of isolates. This predominant profile was widely disseminated in Paraná state. SPM-1 is the main MBL identified in carbapenem-resistant P. aeruginosa in Southern Brazil. The genetic similarity among some isolates suggests a clonal expansion. Copyright © 2016 Elsevier B.V.

    Ambient hygroscopic properties, numbers of size-segregated cloud condensation nuclei (CCN) at different supersaturations (0.1%-0.8%), and the chemical composition of submicron particles were simultaneously measured at a suburban site in northern Japan in summer. Two distinct periods with different growth factors (GF), CCN activation diameters, and chemical compositions were observed. The data suggest that internally mixed sulfate aerosols dominated the accumulation size mode in relatively aged aerosols during the first period, whereas particles observed during the latter periods showed external mixing dominated by organics, which was linked to low hygroscopicity and CCN activity. In particular, the higher loading of water-soluble organic matter (WSOM; 60% of OM by mass) with increased WSOM/sulfate ratios corresponded to a low hygroscopicity parameter derived from the CCN measurement (κCCN = 0.15 ± 0.02) at a dry diameter (Ddry) of 146 nm. The results suggest that WSOM, likely dominated by the influence of biogenic sources, contributed to reducing the hygroscopicity and CCN activation at this particle size. Temporal variations in the number concentrations for low GF mode at Ddry = 49.6 nm were similar to those in the elemental carbon (EC) concentration, suggesting that EC contributed to reducing hygroscopicity at this smaller size. Our results suggest that chemical composition and mixing state are important factors controlling the hygroscopicity and CCN activation of submicron particles. These results provide useful data sets of size-resolved subsaturated and supersaturated hygroscopicity and highlight the importance of the abundance of OM relative to sulfate in predicting the effects on climate change.

    The Northern Pintail is a medium-sized dabbling duck of slender, elegant lines and conservative plumage coloration. It is circumpolar in distribution and abundant in North America, with core nesting habitat in Alaska and the Prairie Pothole Region of southern Canada and the northern Great Plains. Breeders favor shallow wetlands interspersed throughout prairie grasslands or arctic tundra. An early fall migrant, the species arrives on wintering areas beginning in August, after wing molt, often forming large roosting and feeding flocks on open, shallow wetlands and flooded agricultural fields. The birds consume grains, marsh plant seeds, and aquatic invertebrates throughout the fall and winter. Northern Pintails are among the earliest nesting ducks in North America, beginning shortly after ice-out in many northern areas. Individuals form new pair bonds each winter but are highly promiscuous during the nesting season, with mated and unmated males often involved in vigorous, acrobatic Pursuit Flights. Annual nest success and productivity vary with water conditions, predation, and weather. Females build nests on the ground, often long distances from water. Only the female incubates; her mate leaves shortly after incubation begins. Ducklings hatch together in one day, follow the female to water after a day in the nest, and fledge by July or August. Adults and ducklings consume mainly aquatic invertebrates during the breeding season. Predators and farming operations destroy many thousands of Northern Pintail nests annually; farming has also greatly reduced the amount of quality nesting cover available. Winter habitats are threatened by water shortages, agricultural development, contamination, and urbanization. Periods of extended drought in prairie nesting regions have caused dramatic population declines, usually followed by periods of recovery. Over the long term, however, the continental population of Northern Pintails has declined significantly from 6 million birds in

Foi constatado que os preços reais, em nível de produtor e de atacado, decresceram significativamente durante o períodoanalisado. Os preços recebidos pelos produtores estão acima da média nos meses de janeiro a junho e abaixo dela nos demais. As margens de comercialização não apresentaram tendência de crescimento ou declínio no período analisado. A causalidade é do produtor para o atacado. A transmissão de preços foi inferior a um, implicando que, em momentos de elevação dos preços em nível de produtor, as margens do atacadista diminuem, ocorrendo o contrário em situações de redução dos preços pagos aos produtores. The aim of this research was to evaluate some commercialization aspects of the coconut produced in the Northern region of the State of Rio de Janeiro, as well as the transmission mechanisms of its prices between producers and wholesalers. It was evident that actual prices, both for producer and wholesale, decreased significantly during the period analyzed. The producer prices are above average from January to June and below it in the remaining months. Thecommercialization margins did not show trends of growth or decline in the period analyzed. Causality is from producer to wholesaler. The elasticity of price transmission was inferior to one, implying that, at moments of price rise at producer level, the margin of thewholesaler decreases, the opposite occurring in the case of a decrease in producer prices.

    Full Text Available This paper analyzes factors affecting the risk of malaria among individuals working in wildcat gold mining camps (garimpos in northern Mato Grosso State in the Brazilian Amazon. Historically, such mining camps have the locations with the highest malaria prevalence in the Brazilian Amazon. However, little attention has focused on understanding the disease from the internal perspective of the mining camps themselves, such as the mining population's characteristics and its spatial organization. This paper adopts a stepwise logistic model to identify spatial, occupational-exposure, and cultural factors that affect malaria prevalence. According to the results, differences among individuals working and/or living in the gold mining areas could produce different exposure to the disease and thus to different risk of malaria prevalence. Understanding these differences may provide an important tool for identifying risk profiles in the gold mining and related population and for informing programs for prevention and treatment of malaria in the Amazon.O artigo analisa fatores que afetam o risco de malária entre garimpeiros de ouro no norte de Mato Grosso, Brasil. Historicamente, os garimpos apresentam a maior prevalência de malária da Amazônia Legal brasileira. Entretanto, até o momento houve pouca investigação no sentido de compreender a doença desde a perspectiva interna dos próprios garimpos, ou seja, através das características da população garimpeira e da sua organização espacial. O artigo adota um modelo logístico stepwise para identificar fatores territoriais, culturais e de exposição ocupacional que afetam a prevalência da malária. Com base nos resultados, diferenças entre indivíduos que trabalham e/ou vivem nas áreas de garimpo poderiam produzir variações na exposição à doença, levando a um risco diferenciado de prevalência de malária.

    International Nuclear Information System (INIS)

    2002-04-01

    Most analysts agree that demand for natural gas in North America will continue to grow. Favourable market conditions created by rising demand and declining production have sparked renewed interest in northern natural gas development. The 2002 Annual Energy Outlook forecasted U.S. consumption to increase at an annual average rate of 2 per cent from 22.8 trillion cubic feet to 33.8 TCF by 2020, mostly due to rapid growth in demand for electric power generation. Natural gas prices are also expected to increase at an annual average rate of 1.6 per cent, reaching $3.26 per thousand cubic feet in 2020. There are currently 3 proposals for pipelines to move northern gas to US markets. They include a stand-alone Mackenzie Delta Project, the Alaska Highway Pipeline Project, and an offshore route that would combine Alaskan and Canadian gas in a pipeline across the floor of the Beaufort Sea. Current market conditions and demand suggest that the projects are not mutually exclusive, but complimentary. The factors that differentiate northern pipeline proposals are reserves, preparedness for market, costs, engineering, and environmental differences. Canada has affirmed its role to provide the regulatory and fiscal certainty needed by industry to make investment decisions. The Government of the Yukon does not believe that the Alaska Highway Project will shut in Mackenzie Delta gas, but will instead pave the way for development of a new northern natural gas industry. The Alaska Highway Pipeline Project will bring significant benefits for the Yukon, the Northwest Territories and the rest of Canada. Unresolved land claims are one of the challenges that has to be addressed for both Yukon and the Northwest Territories, as the proposed Alaska Highway Pipeline will travel through traditional territories of several Yukon first Nations. 1 tab., 4 figs

    The present report is part of an ongoing study by the Swiss Seismological Service, that was initiated by Nagra almost 20 years ago. It is devoted to the detailed monitoring of the earthquake activity in northern and central Switzerland. The main objective of this study is to provide information about the locations of active deformation and the state of stress in the Earth's crust and to relate these to the geological features visible at the surface. Originally, this seismotectonic investigation was restricted to the northern part of Switzerland; later it was extended also to the central part. Concerning the seismotectonics of northern Switzerland, this report constitutes a continuation of earlier publications. Here we review the seismic activity and earthquake focal mechanisms of the last 10 years and subsequently derive a comprehensive picture of the deformation and stress in the Earth's crust of northern Switzerland, based on all data available up to the end of 1999. Concerning the seismotectonics of central Switzerland, this publication constitutes the first publicly available report. (author) [de

    colonize the receptables placed in reparian forest were collected for this study. MATERIAL AND METHODS: The materials used were: Tires, plastic, can and bamboo receptacles, installed in a rural area of a reparian forest along a river in Northern Parana, Brazil. RESULTS: The results were obtained by means of the collection of Cx.grup coronator, Cx. declarator, Cx. laticlasper, Cx. (Melanoconion, Cx. section Spissipes, Cx. mollis, Ae. terrens, Tr. compressum, Tr. pallidiventer, Hg. leucocelaenus, Cx. quinquefasciatus, Li. durhamii and Toxorhynchites sp larvae. The first five species were tire specific, while the two Trichoprosopon species were bamboo specific. Ae. terrens and Cx. mollis were collected both in tires and bamboo, Cx. bigoti was collected in tires, cans and bamboo, while Hg. leucocelaenus could only be found in cans. The last four species were collected in all kinds of receptacles. Cx. quinquefasciatus, Cx. eduardoi and Li. durhamii had significant population fluctuations. DISCUSSION: Tires were characterized as the receptacle most acceptable to the Culicidae. The areas where the forest was the densest and the places where the soil was the most humid were the spots with the highest capture register.

The Compendium of Pedagogy by Vellozo was published in 1907 and republished in 1975. It was organized in three parts, one for every year of Teachers’ School. The article refers to the first book of the collection. In the first part of that book, there are ten lessons which covers the Pedagogy subject and their methods, organization of school and definitions of educations, as well as several lessons about Ancient, Medieval and Modern History and the prevailing educational thought in each one of them. The book for the second year, which was also organized in ten lesson, emphasizes the teaching methods, didactics, and physical education (health, moral, intellectual aspects. For the third year of course, Vellozo writes lessons about science, geography, history, drawing, music and a special lesson about kindergartens. The Compendium follows the scientific logics that should guide the school practices in that historical period, but also reflects the current culture in Teachers’ School, as well as  it shows the social-economic, political and cultural influences in Brazil and in Parana.

  14. The Bero Volganic Group: New Lithological, Stratigraphic, and Geochemical Data of this Extension of the Parana-Etendeka Igneous Province into SW Angola with Implications

    2015-12-01

    The Bero Volcanic Group, an extension of the Etendeka-Paraná Igneous Province into SW Angola, forms the eroded basement to the on-shore Namibe Basin, an Early Cretaceous-Cenozoic terrestrial and marine sedimentary sequence. The igneous suite outcrops between latitudes 14.68o and 15.25o S and comprises quartz latite rheoignimbrites/lavas, tholeiitic basaltic lavas, pyroclastic/volcaniclastic deposits, minor aeolian sandstones, and mafic tholeiitic dykes and gabbroic sheets. Quartz latite lithologies dominate. In the Rio Bero area in the S quartz latites are underlain by several thin flows of basalt interbedded with, and underlain by, thin discontinuous lenses of aeolian sandstone. This sequence is consistent with the general stratigraphic sequence in the northern Etendeka of Namibia. To the N basalts and aeolian sandstones are absent and the quartz latites lie directly on Precambrian basement rocks in places. To date, data for a quartz latite correlated with a Chapecó rhyolites of the Paraná are available from only one locality in Angola. This study's wider sampling and major and trace element and radiogenic isotope analysis reveals the following: (1) all mafic rocks are high-Ti, the lavas being equivalent to the Khumiba/Urubici type; (2) mafic dykes cutting the quartz latites having affinities to the Paranapanema-Ribeira mafic lavas; (3) five quartz latite geochemical types are present, three of which are known from Etendeka/Paraná (Sarusas/Guarapuava, Khoraseb/Ourinhos and Ventura) and their stratigraphic relationships in Angola are consistent with those in the Etendeka and Paraná; (4) their Angolan occurrence significantly extends the area covered by, and potential eruptive volumes of, these silicic types; (5) two other quartz latite types are unknown in the Etendeka and Paraná and are probably products of low-volume, local eruptions. The Chinguau type is geochemically similar to the low-Ti quartz lalites of the southern Etendeka but has lower Epsilon Nd

  15. Spatial models of Northern Bobwhite populations for conservation planning

    Science.gov (United States)

    Twedt, Daniel J.; Wilson, R. Randy; Keister, Amy S.

    2007-01-01

    Since 1980, northern bobwhite (Colinus virginianus) range-wide populations declined 3.9% annually. Within the West Gulf Coastal Plain Bird Conservation Region in the south-central United States, populations of this quail species have declined 6.8% annually. These declines sparked calls for land use change and prompted implementation of various conservation practices. However, to effectively reverse these declines and restore northern bobwhite to their former population levels, habitat conservation and management efforts must target establishment and maintenance of sustainable populations. To provide guidance for conservation and restoration of habitat capable of supporting sustainable northern bobwhite populations in the West Gulf Coastal Plain, we modeled their spatial distribution using landscape characteristics derived from 1992 National Land Cover Data and bird detections, from 1990 to 1994, along 10-stop Breeding Bird Survey route segments. Four landscape metrics influenced detections of northern bobwhite: detections were greater in areas with more grassland and increased aggregation of agricultural lands, but detections were reduced in areas with increased density of land cover edge and grassland edge. Using these landscape metrics, we projected the abundance and spatial distribution of northern bobwhite populations across the entire West Gulf Coastal Plain. Predicted populations closely approximated abundance estimates from a different cadre of concurrently collected data but model predictions did not accurately reflect bobwhite detections along species-specific call-count routes in Arkansas and Louisiana. Using similar methods, we also projected northern bobwhite population distribution circa 1980 based on Land Use Land Cover data and bird survey data from 1976 to 1984. We compared our 1980 spatial projections with our spatial estimate of 1992 populations to identify areas of population change. Additionally, we used our projection of the spatial

  16. Euroscepticism in Italy: Evolution of Northern League Political Program

    Directory of Open Access Journals (Sweden)

    Oleg N. Barabanov

    2015-01-01

    Full Text Available Abstract: The article examines the key stages of the establishment of Italy’s Northern League as a rightwing hard eurosceptic party. Being initially a continual supporter of European integration and considering the transition to common currency as an opportunity available only to northern regions, which could secede and form an independent state, Northern League after losing the main point of its political agenda when the whole Italy joined the Economic and Monetary Union in 1998, became a eurosceptically-oriented party, which it is up to now. The authors dwell on the focal points of the party’s anti-EU program: Italy’s exit from the eurozone, the formation of Europe of macroregions, the reformation of supranational institutes and decision-making procedures. However, while confronting the Northern League policy with that of National Front in France and UKIP in the United Kingdom, the authors come to the conclusion that Euroscepticism for the former is just a sign of the shift in priorities rather than a strategy as for the latter. This can be explained by the fact that National Front and UKIP are still to fight for the place in the national mainstream, while Northern League has become its integral part long before. Nevertheless, under the new leadership of M.Salvini Northern League managed to become the fourth party on the national level according to the results of European parliament elections in 2014 and established itself as a significant power opponent to EU policy on a number of important issues, such as anti-Russian sanctions. Moreover, frequent visits of party members to Moscow and the party’s outspoken support of Russia on Crimea’s entrance into the Russian Federation provide an opportunity to consider Northern League a potential conductor of Russian interests in the European Union.

  17. All Christians? Experiences of science educators in Northern Ireland

    Murphy, Colette; Hickey, Ivor; Beggs, Jim

    2010-03-01

    In this paper we respond to Staver's article (this issue) on an attempt to resolve the discord between science and religion. Most specifically, we comment on Staver's downplaying of difference between Catholics and Protestants in order to focus on the religion-science question. It is our experience that to be born into one or other of these traditions in some parts of the world (especially Northern Ireland) resulted in starkly contrasting opportunities, identities and practices in becoming and being science educators. The paper starts with a short contextual background to the impact of religion on schooling and higher education in Northern Ireland. We then explore the lives and careers of three science/religious educators in Northern Ireland: Catholic (Jim) and Protestant (Ivor) males who are contemporaries and whose experience spans pre-Troubles to post-conflict and a Catholic female (Colette) who moved to Northern Ireland during the Troubles as a teenager. Finally, we discuss the situation regarding the teaching of creationism and evolution in Northern Ireland—an issue has recently generated high public interest. The Chair of the Education Committee of the Northern Ireland Assembly recently stated that "creationism is not for the RE class because I believe that it can stand scientific scrutiny and that is a debate which I am quite happy to encourage and be part of…" (News Letter 2008). It could be the case that the evolution debate is being fuelled as a deliberate attempt to undermine some of the post-conflict collaboration projects between schools and communities in Northern Ireland.

New reference values of cholesterol, triglycerides and glucose are required to treatment. To determine the reference values of cholesterol, triglycerides and glucose in Hispanic children between 6 and 11 years in the Mexico-USA border. A prospective, cross-sectional, descriptive and observational study. A population of Hispanic children between 6 and 11 years of both boys and girls, belonging to three public institutions in the cities of Ensenada and Chihuahua, randomly selected, were studied. The study variables were the levels of total cholesterol (TC), triglycerides (TG) and glucose (G). From 300 subjects studied just 54 children completed the study. Higher average values of TC (168.7 ± 27.2 mg / dl), TG (80.6 ± 48.4 mg / dl) and G (88.3 ± 8.9 mg / dl) were observed. An additional behavior was founded, never reported previously to the limit of the knowledge of the authors; glucose levels of the children studied decreased with increased of cholesterol and triglycerides. To discard a random relationship between the variables, the Pearson correlation coefficient was determined between waist circumference and BMI, verifying an inverse association with G and direct with the TG. The reference values for Hispanic children between 6 and 11 years living on the northern border of Mexico-USA differ with respect to the national average values of the countries studied. Further studies are needed in larger populations to confirm the trend ob served in glucose levels of normal children, overweight and obese. Copyright AULA MEDICA EDICIONES 2014.

    1998-06-01

    This report is about the market for airline travel in northern New Mexico. Interest in developing a northern New Mexico regional airport has periodically surfaced for a number of years. The New Mexico State Legislature passed a memorial during the 1998 Second Session calling for the conduct of a study to determine the feasibility of building a new regional airport in NNM. This report is a study of the passenger market feasibility of such an airport. In addition to commercial passenger market feasibility, there are other feasibility issues dealing with siting, environmental impact, noise, economic impact, intermodal transportation integration, region-wide transportation services, airport engineering requirements, and others. These other feasibility issues are not analyzed in any depth in this report although none were discovered to be show-stoppers as a by-product of the authors doing research on the passenger market itself. Preceding the need for a detailed study of these other issues is the determination of the basic market need for an airport with regular commercial airline service in the first place. This report is restricted to an in-depth look at the market for commercial passenger air service in NNM. 20 figs., 8 tabs.

    2009-12-01

    The Northern Eurasia Earth Science Partnership Initiative (NEESPI) was launched five years ago with the release of its Science Plan (http://neespi.org). Gradually, the Initiative was joined by numerous international projects and launched in the European Union, Russia, United States, Canada, Japan, and China. Currently, serving as an umbrella for more than 130 individual research projects (always with international participation) and with a 15M annual budget, this highly diverse initiative is in full swing. Since the first NEESPI focus issue (Pavel Groisman et al 2007 Environ. Res. Lett. 2 045008 (1pp)) in December 2007, several NEESPI Workshops and Sessions at International Meetings have been held that strengthen the NEESPI grasp on biogeochemical cycle and cryosphere studies, climatic and hydrological modeling, and regional NEESPI components in the Arctic, non- boreal Eastern Europe, Central Asia, northern Siberia, and mountainous regions of the NEESPI domain. In May 2009, an overview NEESPI paper was published in the Bulletin of the American Meteorological Society (BAMS) (Pavel Groisman et al 2009 Bull. Am. Met. Soc. 90 671). This paper also formulated a requirement to the next generation of NEESPI studies to work towards attaining a higher level of integration of observation programs, process studies, and modeling, across disciplines. Three books devoted to studies in different regions of Northern Eurasia prepared by the members of the NEESPI team have appeared and/or are scheduled to appear in 2009. This (second) ERL focus issue dedicated to climatic and environmental studies in Northern Eurasia is composed mostly from the papers that were presented at two NEESPI Open Science Sessions at the Annual Fall Meeting of the American Geophysical Union (December 2008, San Francisco, CA) and at the General Assembly of the European Geosciences Union (April 2009, Vienna, Austria), as well as at the specialty NEESPI Workshops convened in Jena, Helsinki, Odessa, Urumqi

    Full Text Available This report aims to describe the first case allochthonous of visceral leishmanisasis (VL in the municipality of Campo Mourão, Parana, Brazil, in a canine, Boxer breed, with eye and skin lesions, lymphadenomegaly and splenomegaly, attended at Veterinary Hospital at the Faculdade Integrado de Campo Mourão, after residing in the city of Campo Grande, Mato Grosso do Sul. The diagnosis of the disease was based on direct observation of amastigotes of Leishmania spp., in popliteal lymph nodes, suggesting that a case of VL, since the animal came from an endemic area for the disease. The migration of infected dogs from endemic regions to areas unaffected becomes a problem for public health, since it may allow the installation of new outbreaks by encouraging the spread of disease throughout the country.O presente relato tem por objetivo descrever o primeiro caso alóctone de leishmaniose visceral (LV no município de Campo Mourão, Paraná, Brasil, em um canino, da raça Boxer, apresentando lesões oculares e cutâneas, linfoadenomegalia e esplenomegalia, atendido no Hospital Veterinário da Faculdade Integrado de Campo Mourão, após ter residido na cidade de Campo Grande, Mato Grosso do Sul. O diagnóstico da enfermidade baseou-se na observação direta de formas amastigotas de Leishmania spp., em linfonodos poplíteos, sugerindo ser um caso de LV, uma vez que o animal era proveniente de área endêmica para a enfermidade. A migração de cães infectados de regiões endêmicas para áreas indenes torna-se um problema para a saúde pública, uma vez que poderá permitir a instalação de novos focos, favorecendo a disseminação da doença em todo o país.

    Full Text Available Despite the importance of citriculture in Brazil, very little is known about mite populations in citrus crops in the Northern Region. In the municipality of Manaus, 12 sprayed sweet orange orchards were surveyed every two weeks during seven months to record mite species amount, and to describe the abundance and distribution of the most important species. The size and age of the orchards varied from 3,360 to 88,080 m² and seven to 25 years, respectively. In the fourteen sampling period, leaves, twigs and fruits were collected from 12 trees, one per orchard. In total, 3,360 leaves, 672 twigs and 1,344 fruits were sampled from 168 trees. Mites were manually extracted from the fruits, and by the washing method on leaves and twigs. We identified pests with the potential to cause economic loss. Fourteen species of phytophagous and mycophagous mites from Eriophyidae, Tarsonemidae, Tenuipalpidae, and Tetranychidae were recorded. Brevipalpus phoenicis (Geijskes 1939 and Phyllocoptruta oleivora (Ashm., 1879, the two commonest phytophagous mites in other Brazilian regions were dominant, showing that local orchards are susceptible to their infestation. Eleven predatory mites were recorded, comprising 10% of the mite population, belonging to Phytoseiidae and Ascidae. Phytoseiidae was the richest family, with ten species. The results are discussed in relation to the temporal variation aspects and habitat use of the most important species. Long-term research encompassing chemical applications followed by evaluations of the mite community are necessary for a better management of the orchards, taking into consideration the seasonal phenology of key pests.Apesar da importância da citricultura no Brasil, pouco se conhece sobre as populações de ácaros em plantações de citros no norte do país.

    Full Text Available The aim of this study was to determine the occurrence of intestinal parasites in a quilombola community from the northern Espírito Santo, Brazil. Descendants of slaves who arrived in Brazil in the sixteenth century, this population settled in the municipality of São Mateus in 1858. Fresh fecal samples from 82 individuals who agreed to participate in the study were collected between August 2009 and July 2010, and immediately sent to the Clinical Laboratory of the Centro Universitário Norte do Espírito Santo of the Universidade Federal do Espírito Santo for analysis. Out of all the participants, 36 (43.9% were male and 46 (56.1% were female, whose ages ranged from six to 85 years. The study of the occurrence of intestinal parasites indicated that 35 individuals (42.7% were infected with at least one intestinal parasite. Among helminths, the most frequent were hookworms, with a rate of 14.6%. With regard to protozoa, Entamoeba coli, Entamoeba histolytica/Entamoeba dispar and Endolimax nana stood out, with frequencies of 23.2%, 8.5% and 4.9%, respectively. The occurrence of biparasitism was observed in 13 of the 82 subjects, accounting for 15.8%, and no cases of multiple parasitic infections were observed. It was concluded that the reduction of cases of intestinal diseases due to parasites will only be achieved with the improvement of basic sanitation and quality of life of quilombola populations.O objetivo do presente estudo foi determinar a ocorrência de parasitos intestinais em população quilombola do Norte do Espírito Santo.

    The difficulties in obtaining reliable data on remittances to Mexico by Mexican immigrants in the United States are first outlined. An analysis of such remittances is then attempted using data from a recent survey, the Encuesta sobre Migracion en la Frontera Norte. Data from this survey are used to analyze several aspects of remittances "such as the direct determination of the amount of the remittances and the identification of the immigrants that send them according to their social and demographic features, and the location of Mexican zones where the remittances arrive, [and] the variations in the amount and frequency of the remittances among the different groups of immigrants."

  19. Northern Ireland in Transition: The Role of Justice

    Directory of Open Access Journals (Sweden)

    Christian Mailhes

    2005-03-01

    Full Text Available All post-conflict societies switching to constitutional liberal democracies have to deal with their past through transitional justice mechanisms that offer to hear the victims, try the perpetrators of all types of abuses, introduce peace and reconciliation schemes. It is time for state and non-state organs to account for past crimes. Several countries have successfully tested such mechanisms. Northern Ireland is the ideal ground for transitional justice to operate but it dispels foreign tailor-made models. However, a number of major reforms and projects have addressed sensitive issues in the wake of the Good Friday Agreement. Two key institutions, the police and the criminal justice system, whose responsibility in the conflict was undeniable, have been reformed. Law and lawyers are concerned with these changes and the introduction of a Human Rights culture in Northern Ireland. A clear break with the past must be achieved for transitional justice mechanisms to work successfully.

    An extensive review is presented on petroleum and chlorinated hydrocarbon pollution in waters and marine organisms of the North Atlantic and of the North, Baltic, Norwegian, and Barents Seas. Data are presented on the bioaccumulation of those pollutants in the organs and tissues of sea birds and of marine biota at various trophic levels. The effects of pollutants on plankton in northern seas are discussed. Factors affecting the bioaccumulation of toxic substances in fish are also examined. It has been discovered that residual quantities of polychlorinated biphenyls, chlorinated pesticides and their metabolites, and petroleum hydrocarbons are present everywhere at all water levels in northern seas. Of particular concern is the fact that maximum concentrations of contaminants have been recorded in the most productive regions, including shelf and estuary zones, the euphotic zone, and areas of upwelling. Both individual toxic substances and their combinations disrupt normal functioning of ecosystems in northern seas, causing a change in the level of primary production and a decline in fish productivity. Pollutant accumulation in commercially valuable organisms represents a serious threat to human health. 424 refs., 13 figs., 15 tabs

    Nigeria, a country located in the Western part of Africa has been the site of numerous kingdoms and tribal states over the millennia and is divided in to Northern and Southern parts with the Hausa-Fulani’s, a diverse but culturally homogeneous people living in the northern part of Nigeria. The vernacular architecture of the Northern Nigeria (VANN) is perhaps one of the least known but most beautiful of the medieval age, over the centuries a tradition of fine architecture has flourished in the area, the variety and quality of buildings are bound to generate much delight and enthusiasm in anyone who is interested in buildings. Many of their early buildings such as mosques and palaces are bright and colorful. This architectural style is known as Tubali which means the traditional architecture in the Hausa language and globally known as Vernacular Architecture (VA). VANN has many unique features which distinguish it from any other architecture. All buildings, be it modern or old has an impact on the environment; hence the need for sustainable measures and practices regarding such buildings. The aim of this research paper is to examine the features of VANN in the light of sustainability. Reviewed literatures were used to identify the various features of the Vernacular Architecture in the Northern Nigeria which were critically examined in the light of sustainability and its concept. The result showcased the various features of VANN in the light of sustainability and also discussed the factors hindering the sustainable endeavors of VANN with respect to such features.

    In the northern semi-arid and semi-humid region of Minas Gerais State, in the southeast Brazil, substantial part of the water supplying is produced by means of deep wells. In several localities the fluoride concentrations are higher than 1.5 mg/L, maximum acceptable limit for drinking water, endangering the public supply and the public health. Endemies of dental fluorosis have been detected since the decade of 1990. The cause of this problem has been associated to the consumption of local drinking water. Current studies indicate the occurrences of fluorite in the limestones of the Bambui Group as the main mineral-source for the fluoride content in the groundwater, however without identifying the specific contribution of each hydrostratigraphic unit. This work shows the results of stratigraphic studies and hydro-chemical analysis of 144 deep wells and the influence of the carbonatic facies in the fluoride concentrations of the water. Fluoride concentrations are related to fluorite occurrences/mineralizations (lithostratigraphic control) and to circulation depth of groundwater (geochemical control), newly distinguishing three hydrostratigraphic units. The correlation analysis of hydrogeochemic parameters (F-, Mg{sub 2}+, SO{sub 4}{sup 2}- and electric conductivity) corroborates these grouping into three units. The probability of the contamination by fluoride, as a function of the hidroestratigraphic units, in decreasing order, seems to be: top level of the Sete Lagoas Formation; Lagoa do Jacare Formation; and botton and middle levels of the Sete Lagoas Formation.

    1998-11-01

    In the genus Sorocea A. St.-Hil. (Moraceae) the species group of the coastal Atlantic from Brazil presents similar morphological taxa with taxonomical difficulties. Using a combined approach, linking morphology, ecology and biogeography and the concept of the Functional Biological Unit (FBU) it was possible to define and to specify the taxonomic ranks of nine FBUS, five considered as valid species of which one is new to science, four are subspecies and one is not described. All of these species, most of which are endemic to a restricted area, appear to be the result of a relatively recent and intense speciation caused by a phenomena of vicariance related to a rich and complex palaeohistory of the region (palaeoclimates; variations in the course of rivers, and in particular the Parana and Atlantic Mountains refugia).

    This work deals with the measurement of radioactive lines in powdered milk, with high resolution gamma spectrometry, using a HPGe detector with relative efficiency of 10%, coupled to the electronic nuclear chain and a multichannel card of 8192 channels. Some tests were realized before beginning the measurements. The first of them was to define the shield to be used, making several measured with different shields according to the available materials, opting finally for a shield composed of bricks of lead (10 cm thickness), plates of iron (4nm thickness) and of aluminum (2 mm thickness). Four different geometries for the samples recipients were tested, and the Marinelli beaker of 2,1 liters totally filled was the one which supplied the best peak/background ratio. A statistical inference was also realized to determine the sampling that represents each one of the lots of milk to be measured, resulting in a number of 6 samples, for a confidence level of 95%. Two different kinds of powdered milk produced at Londrina were analyzed, Integral Powdered Milk Cativa and Integral Powdered Milk Polly. The samples were properly put in the Marinelli beaker of 2,1 L, sealed and kept for 40 days to reach the secular equilibrium. The counting time for each measurement was two days. It was possible to identify the radionuclides {sup 40} K, {sup 137} Cs and {sup 232} Th (from {sup 208} Tl), whose activities were calculated according to the International Atomic Energy Agency norms (IAEA, 1989). The detector efficiency was measured using calibrated samples, prepared with the certified reference materials IAEA-326 and IAEA-375. Corrections for self-absorption were accomplished, based on measures of samples with different densities. The results obtained for the powdered milk Cativa were: 464{+-} 12 Bq/kg for {sup 40} K, 3,46 {sup {+-}} 1,05 and 0,46 {+-} 1,05 and 0,46 {+-} 0,16 Bq/kg for the minimum detectable activities of {sup 137} Cs and {sup 232} Th, respectively. For the milk Polly, the results were: 452{+-}10 Bq/kg for {sup 40} K, 3,19{sup {+-}} 0,63 and 0,32{sup {+-}} 0,12 Bq/kg for the minimum detectable activities of {sup 137} Cs and {sup 232} Th, respectively. The statistical analyses performed checked the measurements repeatability by means of the Tukey's average comparison test. A correlation analysis between standard deviations and the mean showed the absence of significant systematic deviation. Comparison the results obtained with literature, it was demonstrated that the values of the activities found are within the normal levels of radioactivity for this kind of product and below the maximum permissible levels established by CNEN, that is, the analyzed milk can be normally consumed. On the other hand, the implemented methodology present a good performance, faced to the available experimental conditions. (author)

    Secondary energy can be described as a surplus of electrical energy in hydraulic power plant due to the lower demand of energy during some periods of time, and the excess of water in the reservoir, during rainy periods. The largest hydroelectric power plant both in Brazil and South America is Itaipu, jointly operated by Brazil and Paraguay. This power plant has a large amount of secondary energy available, and this energy is lost as no turbine spilled water out of the reservoir. This study proposes the using of this energy for electrolytic hydrogen production and ammonia for nitrogenous fertilizers. The hydrogen is produced as a gas by mean of electrolyses and with the atmospheric nitrogen for the electrolytic ammonia synthesis, used as the most important raw material for the nitrogen fertilizers synthesis. This study performs the determination of the minimal cost of hydrogen production and the correspondent hydrogen production capacity in accordance with the ammonia market for nitrogenated fertilizers in the Center/South region, estimating the better production capacity for an ammonia plant to be installed close to Itaipu.

Weather ability tests were also performed, not only through wetting-drying cycles and by immersion in ethylene glycol but by outdoor exposure as well, using crushed and core drilled specimens. Detailed procedures for the weather ability test using core specimens from rotary drilling are given. It is analyzed the influence of a geological feature (fault zone, about 10 meters thick and 20 degrees dip), that occurs in the rock mass foundation, on the technological properties of these rocks. Basaltic litotypes selected as construction material are then pointed out. (author)

    Full Text Available Plantas do gênero Senna causam miopatia degenerativa em bovinos e o maior número de relatos envolve Senna occidentalis. O objetivo desse trabalho é relatar, pela segunda vez no Brasil, um surto de intoxicação natural por Senna obtusifolia. É descrito um surto de intoxicação por Senna obtusifolia, na região noroeste do estado do Paraná, que aconteceu em um lote de 200 vacas, com idade entre 45 e 152 meses, introduzidas em um confinamento para melhorar a condição corporal antes do parto. A área do confinamento estava invadida pela planta e as vacas permaneceram no local durante oito dias. Entre quatro e nove dias após a entrada no confinamento 20 vacas adoeceram e somente uma se recuperou. Os sinais consistiram em mioglobinúria, incoordenação e decúbito esternal permanente. As vacas doentes apresentaram aumento das atividades das enzimas creatina quinase, aspartato aminotransferase, gamaglutamiltransferase e fosfatase alcalina. Lesões na musculatura esquelética dos membros posteriores caracterizadas por áreas pálidas representaram as principais alterações observadas à necropsia de quatro bovinos. Necrose segmentar multifocal da musculatura esquelética e necrose paracentral multifocal no fígado foram as alterações histopatológicas mais relevantes. As evidências epidemiológicas, clínicas e patológicas indicam o diagnóstico de intoxicação por Senna obtusifolia. A planta demonstrou ter efeito miotóxico e hepatotóxico nos animais intoxicados e a doença foi quase sempre fatal.Plants of the genus Senna cause a degenerative myopathy in cattle and most of the reports refer to Senna occidentalis. The aim of this paper is to report, for the second time in Brazil, an outbreak of natural poisoning by Senna obtusifolia. It happened in the northwestern Paraná in a herd of 200 cows, 45 to 152 months of age, which had been placed into a feedlot to improve their nutritional status before the calving period. The cows stayed for eight days in this feedlot infested by the plant. Four to nine days after they got into the feedlot, 20 cows became ill and only one recovered. The clinical signs consisted of myoglobinuria, incoordination and permanent sternal recumbency. The affected cows showed increased activity of creatine phosphokinase, aspartate aminotransferase, gama-glutamyltransferase, and alkaline phosphatase. The main postmortem changes were in skeletal muscles of the hind limbs characterized by pale areas. The histological alterations were multifocal segmental necrosis of skeletal muscles and hepatic multifocal paracentral necrosis. Epidemiological, clinical and pathological data led to the diagnosis of Senna obtusifolia poisoning. The plant showed miotoxic and hepatotoxic effects on the poisoned animals and the disease was almost always lethal.

    Northern peatlands are important in regulating the global climate. While sequestering carbon dioxide, these peatlands release ca. 24-39 Tg methane annually to the atmosphere. This is 5-20 % of the annual anthropogenic methane emissions to the atmosphere. The greenhouse gas balance of peatlands may change as a consequence of water level draw-down after land-use change, or if summers become warmer and drier, as has been predicted for high latitudes after climatic warming. Subsequent emissions of methane would decrease, whereas emissions of carbon dioxide and nitrous oxide would increase. Within the Finnish Research Programme on Climate Change (SILMU), the research project `Carbon Balance of Peatlands and Climate Change` (SUOSILMU) has been under progress since 1990. It is a co-operative research project, with research groups from the Universities of Helsinki and Joensuu, the Finnish Forest Research Institute, the National Public Health Institute and the Finnish Environment Agency. The research consortium of this project organised a workshop entitled `Northern Peatlands in Global Climatic Change - Hyytiaelae Revisited` October 8-12, 1995. The main objective of the workshop was to review the state of the art of the carbon cycling research in natural and managed peatlands. The role of peatlands in the greenhouse effect, their response and feedback to the predicted climate change, and the consequences of land-use changes were assessed, and the future research needs were evaluated. The latest information on the role of peatlands in the atmospheric change was given in 50 posters and 4 key lectures. Results of SUOSILMU projects were demonstrated during a 1-day field excursion to one of the intensive study sites, Lakkasuo near Hyytiaelae

    Full Text Available Durante fines del siglo XIX y principios del siglo XX tuvieron lugar varias exploraciones y excavaciones en sitios arqueológicos del humedal del Paraná inferior, originando en consecuencia un gran acervo de materiales bioarqueológicos, entre otros, depositados hoy en día en el Museo de la Plata de la Universidad Nacional de La Plata y en el Museo Etnográfico de la Universidad de Buenos Aires. Si bien algunos de los resultados derivados de aquellos trabajos de campo fueron publicados, otros permanecen inéditos. El objetivo de este trabajo es dar a conocer algunas características de dichas colecciones bioarqueológicas a través del análisis de 252 individuos que las conforman. En este sentido, procedimos a la determinación sexual y estimación etaria de la muestra y al registro de variables tafonómicas, este último con el fin de poder identificar el posible contexto de inhumación de donde provienen dichos individuos. A partir de este análisis y siguiendo los datos publicados se discriminaron entre inhumaciones en contacto directo con la tierra o en urnas. A su vez, se dio cuenta de una segmentación espacial en base a categorías de sexo y edad para algunos sitios, como así también de la presencia de adornos personales de metal, ocre y marcas de corte en algunos huesos. De esta manera, esperamos resaltar el valor que tienen las colecciones de museos como así también contribuir y ampliar nuestro conocimiento sobre las características de las poblaciones prehispánicas de la región.  Abstract  At the end of the 19th and beginning of the 20th century several explorations and excavations took place in archaeological sites at the lower Parana wetland, giving rise, among others, to a vast body of bioarchaeological remains, currently deposited at the Museo de la Plata de la Universidad Nacional de La Plata and at the Museo Etnográfico de la Universidad de Buenos Aires.

  10. Hypoxia in the Northern Gulf of Mexico

    Energy Technology Data Exchange (ETDEWEB)

    Dale, Virginia H [ORNL

    2010-01-01

    Since 1985, scientists have been documenting a hypoxic zone in the Gulf of Mexico each year. The hypoxic zone, an area of low dissolved oxygen that cannot support marine life, generally manifests itself in the spring. Since marine species either die or flee the hypoxic zone, the spread of hypoxia reduces the available habitat for marine species, which are important for the ecosystem as well as commercial and recreational fishing in the Gulf. Since 2001, the hypoxic zone has averaged 16,500 km{sup 2} during its peak summer months, an area slightly larger than the state of Connecticut, and ranged from a low of 8,500 km{sup 2} to a high of 22,000 km{sup 2}. To address the hypoxia problem, the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force (or Task Force) was formed to bring together representatives from federal agencies, states, and tribes to consider options for responding to hypoxia. The Task Force asked the White House Office of Science and Technology Policy to conduct a scientific assessment of the causes and consequences of Gulf hypoxia through its Committee on Environment and Natural Resources (CENR). In 2000 the CENR completed An Integrated Assessment: Hypoxia in the Northern Gulf of Mexico (or Integrated Assessment), which formed the scientific basis for the Task Force's Action Plan for Reducing, Mitigating, and Controlling Hypoxia in the Northern Gulf of Mexico (Action Plan, 2001). In its Action Plan, the Task Force pledged to implement ten management actions and to assess progress every 5 years. This reassessment would address the nutrient load reductions achieved, the responses of the hypoxic zone and associated water quality and habitat conditions, and economic and social effects. The Task Force began its reassessment in 2005. In 2006 as part of the reassessment, USEPA's Office of Water, on behalf of the Task Force, requested that the U.S. Environmental Protection Agency (USEPA) Science Advisory Board (SAB) convene an independent

  11. Groundwater management in northern Iraq

    2009-03-01

    Groundwater is vital and the sole resource in most of the studied region of northern Iraq. It has a significant role in agriculture, water supply and health, and the elimination of poverty in rural areas. Although Iraq is currently dramatically disturbed by complex political and socio-economic problems, in its northern part, i.e. the Kurdish-inhabited region, fast urbanization and economic expansion are visible everywhere. Monitoring and water management schemes are necessary to prevent aquifer over-exploitation in the region. Artificial recharge with temporary runoff water, construction of subsurface dams and several other aquifer management and regulation measures have been designed, and some implemented, in order to improve the water situation. Recommendations, presented to the local professionals and decision-makers in water management, include creation of Water Master Plans and Water User Associations, synchronization of drilling programmes, rehabilitation of the existing well fields, opening of new well fields, and the incorporation of new spring intakes in some areas with large groundwater reserves, as well as construction of numerous small-scale schemes for initial in situ water treatment where saline groundwater is present.

    2005-01-01

    This presentation described the Northern Lights Project and addressed the unique characteristics of oil sands which have led to innovative mine and extraction techniques. A table indicating the mining projects in development was presented with reference to recoverable bitumen and ore grade. The marketing aspects of synthetic crude that influence the choice of bitumen upgrader design and economics were discussed. It was noted that new pipeline developments should open up new market opportunities. The expected market for Synenco crude is the northern portion of the United States Midwest. There may also be a possibility to sell the product as diluent because Synenco crude has a lower vacuum gas oil (VGO) content and more naphtha than other synthetic crude. The properties of Synenco crude components were listed with reference to gravity, density, sulfur content, cetane number, smoke point, and feed quality. The trade-off between capital costs, operating cost and risk mitigation was also examined. tabs., figs

    2010-01-01

    Introduced populations of northern pike Esox lucius have provided angling opportunities in the western United States (McMahon and Bennett 1996). However, the northern pike is a voracious piscivore and its large size, high fecundity, and broad physiological tolerance make it capable of drastically altering ecosystems it invades (Marchetti et al. 2004). Indeed, predation by northern pike has been shown to significantly alter fish community structure and put native fishes at a higher extinction risk (He and Kitchell 1990, Findlay et al. 2000). Predation by northern pike is viewed as a significant threat to native stocks of salmonids in Washington, British Columbia, and California (McMahon and Bennett 1996, California Department of Fish and Game [CDFG] 2003).

  16. Migration transition in small Northern and Eastern Caribbean states.

    Mcelroy, J L; De Albuquerque, K

    1988-01-01

    1 area of intra-Caribbean migration that has been overlooked is the "migration transition"--the transformation of rapidly modernizing societies from net labor exporters to net labor importers. This article assembles 8 case studies to 1) briefly present a spectrum of migration experiences in the Caribbean, 2) uncover some transitions under way, 3) pinpoint the forces that underlie the migration transition, and 4) point out some of the more important policy implications of labor migration reversals. The 8 island societies sampled for illustration purposes include 1) the Bahamas and the US Virgin Islands as post-migration transition societies (Zelinsky's advanced society), 2) the British Virgin Islands and the Cayman Islands as undergoing transition (Zelinsky's late transitional society), and 3) Anguilla, St. Kitts-Nevis, Turks and Caicos, and Montserrat as premigration transition societies (Zelinsky's early transitional society). Population data for the islands were derived primarily from the West Indian censuses and government statistics. These 8 historical sketches reveal certain commonalities. All are at various stages in a long-term economic restructuring to displace traditional staple crops with more income elastic, high value export services. In such societies, population growth and progress along the migration transition is an increasing function of this kind of successful export substitution. In addition, along the migration and economic transitions, such insular economies exhibit a relatively large public sector (20-30% of all activity), declining unemployment, increasing fiscal autonomy, and are committed to a development strategy remarkably similar to the "successful" model of the Bahamas and the US Virgin Islands. Cursory evidence suggests that, because of intersectoral competition for land and labor, there is an inverse relationship between farm effort/manufacturing employment and tourism intensity. This review suggests that small islands undergoing rapid growth imperatives also experience a similar set of self-reinforcing socioeconomic and environmental imbalances. Particularly for post-transition and transition societies, these spillovers include increasing real estate speculation and inflation because of tourism and the allied development of retirement colonies of affluent North Americans, wage pressures and skilled manpower shortages, and increasing vulnerability to international business cycles.
