  2. LG tools for asymmetric wargaming

    Science.gov (United States)

    Stilman, Boris; Yakhnis, Alex; Yakhnis, Vladimir

    2002-07-01

    Asymmetric operations represent conflict where one of the sides would apply military power to influence the political and civil environment, to facilitate diplomacy, and to interrupt specified illegal activities. This is a special type of conflict where the participants do not initiate full-scale war. Instead, the sides may be engaged in a limited open conflict or one or several sides may covertly engage another side using unconventional or less conventional methods of engagement. They may include peace operations, combating terrorism, counterdrug operations, arms control, support of insurgencies or counterinsurgencies, show of force. An asymmetric conflict can be represented as several concurrent interlinked games of various kinds: military, transportation, economic, political, etc. Thus, various actions of peace violators, terrorists, drug traffickers, etc., can be expressed via moves in different interlinked games. LG tools allow us to fully capture the specificity of asymmetric conflicts employing the major LG concept of hypergame. Hypergame allows modeling concurrent interlinked processes taking place in geographically remote locations at different levels of resolution and time scale. For example, it allows us to model an antiterrorist operation taking place simultaneously in a number of countries around the globe and involving wide range of entities from individuals to combat units to governments. Additionally, LG allows us to model all sides of the conflict at their level of sophistication. Intelligent stakeholders are represented by means of LG generated intelligent strategies. TO generate those strategies, in addition to its own mathematical intelligence, the LG algorithm may incorporate the intelligence of the top-level experts in the respective problem domains. LG models the individual differences between intelligent stakeholders. The LG tools make it possible to incorporate most of the known traits of a stakeholder, i.e., real personalities involved in

    In order to discuss analytically spatial aspects of recorded sound William Moylan’s concept of ‘sound stage’ is developed within a musicological framework as part of a sound paradigm which includes timbre, texture and sound stage. Two Michael Jackson songs (‘The Lady in My Life’ from 1982 and ‘Scream’ from 1995) are used to: a) demonstrate the value of such a conceptualisation, and b) demonstrate that the model has its limits, as record producers in the 1990s began ignoring the conventions of...

    2008-12-01

    We present a broadband tomographic model of Lg attenuation in the Middle East derived from source- and site-corrected amplitudes. The study region spans from Turkey through the Arabian Peninsula and Iran to Pakistan, Afghanistan, and northwest India. Absolute amplitude measurements are made on hand-selected and carefully windowed seismograms for tens of stations and thousands of crustal earthquakes resulting in excellent coverage of the region. We have modified the standard attenuation tomography technique to more explicitly define the earthquake source expression in terms of the seismic moment. This facilitates the use of the model to predict the expected amplitudes of new events, an important consideration for earthquake hazard or explosion monitoring applications. We will discuss the updated method and implications of this parameterization. A conjugate gradient method is used to tomographically invert the amplitude dataset of over 8000 paths. We solve for Q variation, as well as site and source terms, for a wide range of frequencies ranging from 0.5 -- 10 Hz. The attenuation results have a strong correlation to tectonics. Shields have low attenuation, while tectonic regions have high attenuation, with the highest attenuation at 1 Hz found in eastern Turkey. The results also compare favorably to other studies in the region made using Lg propagation efficiency, Lg/Pg amplitude ratios and two-station methods. We tomographically invert the amplitude measurements for each frequency independently. In doing so, it appears the frequency-dependence of attenuation is not compatible with the power law representation of Q(f). This research was performed under the auspices of the U.S. Department of Energy by the Lawrence Livermore National Laboratory under contract number DE-AC52-07NA27344.

    Trevino, Kelly M; Desai, Kavita; Lauricella, Shauna; Pargament, Kenneth I; Mahoney, Annette

    2012-01-01

    This study applied religious coping theory to examine the relationship between participants' perceptions that lesbian and gay (LG) individuals desecrate Christian values (the stressor) and anti-LG attitudes (the response) and whether religious coping influences the relationship between these variables. Greater agreement with desecration messages was associated with higher levels of anti-LG attitudes. Positive religious coping was associated with lower levels of anti-LG attitudes while negative religious coping was associated with higher levels. Greater exposure to messages that LG individuals desecrate Christian values was associated with greater agreement with those messages. Longitudinal studies with more diverse samples are needed to examine causality and the generalizability of the findings. However, these results have implications for preventing and mitigating anti-LG attitudes.

    1993-01-01

    The q-difference system satisfied by Jackson integrals with a configuration of A-type root system is studied. We explicitly construct some linear combination of Jackson integrals, which satisfies the quantum Knizhnik-Zamolodchikov equation for the 2-point correlation function of q-vertex operators, introduced by Frenkel and Reshetik hin, for the quantum affine algebra U q (sl 2 ). The expression of integrands for the n-point case is conjectured, and a set of linear relations for the corresponding Jackson integrals is proved. (orig.)

  16. The Physical Basis of Lg Generation by Explosion Sources

    2004-12-20

    The goal of this project has been to develop a quantitative predictive capability for explosion-generated Lg phases with a sound and unambiguous physical basis. The research program consisted of a theoretical investigation of explosion-generated Lg combined with an observational study. The specific question addressed by this research program is how the Lg phase is generated by underground nuclear explosions. This question is fundamental to how Lg phases are interpreted for use in explosion yield estimation and earthquake/explosion discrimination. To constrain modeling, we have extensively reviewed the existing literature and complemented that work with an examination of several explosion data sets, most notably: (1) Degelen Mountain explosions recorded between 7 and 57 km, with corresponding recordings at Borovoye, at approximately 650 km; (2) recordings from Russian deep seismic sounding experiments; (3) NTS explosion sources including the NPE and nuclear tests covering a range of source depths and media properties. A simple point explosion in an infinite medium generates no shear waves, so the Lg phase is generated entirely by non-spherical components of the source and conversions through reflections and scattering. We find that the most important contributors to the Lg phase are: (1) P to S conversion at the free surface and other near source interfaces, (2) S waves generated directly by a realistically distributed explosion source including nonlinear effects due to the free surface and gravity, and (3) Rg scattering to Lg. Additional effects that contribute significantly to Lg are scattering of converted S phases that traps more of the converted P-to-S in the crust, and randomization of the components of Lg. The pS phase from a spherically symmetric explosion source in media with P-wave velocity less than upper mantle S-wave velocity is trapped in the crust and can explain the observed radial and vertical Lg. The free surface pS converted phase from the same

    Wang, S.; Zhang, S.; Yang, H.; Xie, J.; Jiang, S.; Feng, G.; Zhou, S.

    2018-05-01

    Direct emission of a chirality controllable ultrafast LG01 mode vortex optical beam from a conventional z-type cavity design SESAM (SEmiconductor Saturable Absorber Mirror) mode locked LD pumped Yb:Phosphate laser has been demonstrated. A clean 360 fs vortex beam of ˜45.7 mW output power has been achieved. A radial shear interferometer has been built to determine the phase singularity and the wavefront helicity of the ultrafast output laser. Theoretically, it is found that the LG01 vortex beam is obtained via the combination effect of diagonal HG10 mode generation by off-axis pumping and the controllable Gouy phase difference between HG10 and HG01 modes in the sagittal and tangential planes. The chirality of the LG01 mode can be manipulated by the pump position to the original point of the laser cavity optical axis.

    Science.gov (United States)

    1992-09-01

    The opinions and a biographical sketch of Wes Jackson, the founder of the Land Institute, are presented. The land Institute near Salina, Kansas is a nonprofit organization devoted to sustainable agriculture. Opinions are provided on the relationship of the Land Institute to sustainable agriculture, the definition of sustainability, the feasibility of replication of his work, his ideas about the destruction wreaked by the plow vs. the sword, technology and population growth, the future farmer, and the speed with which modern science has destroyed the ozone layer. Sustainable agriculture is using the prairie to provide answers to how agriculture can work with nature; the approach will take longer but will sustain both agriculture and people for another 10,000 years. The system runs on sunlight and recycles all materials and is based on the principles of ecosystems, which have been around for hundreds of years. Agricultural technology is based on a fossil fuel intensive infrastructure and is "parachuted into Third World countries." "Corn - the gift of the gods has been the killer of this continent." 50% of the topsoil has been lost, and soil is more important than oil. Advances in biotechnology are seen as the "human cleverness" approach; the preference is for an ecological approach first. Biotechnology tells how to "spin wheels faster," but it also generates more waste. The future farmer is more like the 19th century British naturalist. A projection is that 1st the oil is used up, then the natural gas, and when nuclear power is embraced, Murphy's Law must be repealed. It is important to understand the "we can'ts". Realization of limits will direct energy to the sun's potential and recycling and the flow of energy. Descartes' notion of correctable ignorance must be repudiated. Our knowledge-based world has led to acid rain, global warming, the ozone hole, and Chernobyl. It took just 25 years for chlorofluorocarbons to destroy the ozone layer. A philosophical shift in

  3. Process and progress: John Hughlings Jackson's philosophy of science.

    Science.gov (United States)

    Jacyna, L Stephen

    2011-10-01

    Some scepticism has been voiced over whether the work of John Hughlings Jackson possesses any significant philosophical orientation. This article argues that Hughlings Jackson was acquainted with the work of a wide range of philosophers. In particular, certain aspects of the writings of John Stuart Mill are reflected in Hughlings Jackson's own work. From early in his career, Hughlings Jackson adopted a critical stance in his neurological papers, seeking to expose shortcomings in the conventional practices of his peers and urging greater methodological rigour and sophistication in order to advance their science. This critical and 'procedurist' bias endows Hughlings Jackson's writings with a characteristically modern character.

  5. Adversarial reasoning and resource allocation: the LG approach

    Science.gov (United States)

    Stilman, Boris; Yakhnis, Vladimir; Umanskiy, Oleg; Boyd, Ron

    2005-05-01

    Many existing automated tools purporting to model the intelligent enemy utilize a fixed battle plan for the enemy while using flexible decisions of human players for the friendly side. According to the Naval Studies Board, "It is an open secret and a point of distress ... that too much of the substantive content of such M&S has its origin in anecdote, ..., or a narrow construction tied to stereotypical current practices of 'doctrinally correct behavior.'" Clearly, such runs lack objectivity by being heavily skewed in favor of the friendly forces. Presently, the military branches employ a variety of game-based simulators and synthetic environments, with manual (i.e., user-based) decision-making, for training and other purposes. However, without an ability to automatically generate the best strategies, tactics, and COA, the games serve mostly to display the current situation rather than form a basis for automated decision-making and effective training. We solve the problem of adversarial reasoning as a gaming problem employing Linguistic Geometry (LG), a new type of game theory demonstrating significant increase in size in gaming problems solvable in real and near-real time. It appears to be a viable approach for solving such practical problems as mission planning and battle management. Essentially, LG may be structured into two layers: game construction and game solving. Game construction includes construction of a game called an LG hypergame based on a hierarchy of Abstract Board Games (ABG). Game solving includes resource allocation for constructing an advantageous initial game state and strategy generation to reach a desirable final game state in the course of the game.

  10. Insights into variability of actinorhodopsin genes of the LG1 cluster in two different freshwater habitats.

    Directory of Open Access Journals (Sweden)

    Jitka Jezberová

    Full Text Available Actinorhodopsins (ActRs are recently discovered proteorhodopsins present in Actinobacteria, enabling them to adapt to a wider spectrum of environmental conditions. Frequently, a large fraction of freshwater bacterioplankton belongs to the acI lineage of Actinobacteria and codes the LG1 type of ActRs. In this paper we studied the genotype variability of the LG1 ActRs. We have constructed two clone libraries originating from two environmentally different habitats located in Central Europe; the large alkaline lake Mondsee (Austria and the small humic reservoir Jiřická (the Czech Republic. The 75 yielded clones were phylogenetically analyzed together with all ActR sequences currently available in public databases. Altogether 156 sequences were analyzed and 13 clusters of ActRs were distinguished. Newly obtained clones are distributed over all three LG1 subgroups--LG1-A, B and C. Eighty percent of the sequences belonged to the acI lineage (LG1-A ActR gene bearers further divided into LG1-A1 and LG1-A2 subgroups. Interestingly, the two habitats markedly differed in genotype composition with no identical sequence found in both samples of clones. Moreover, Jiřická reservoir contained three so far not reported clusters, one of them LG1-C related, presenting thus completely new, so far undescribed, genotypes of Actinobacteria in freshwaters.

    Sanborn, Christopher J.; Cormier, Vernon F.

    Comprised of S waves trapped in Earth's crust, the high frequency (2-10 Hz) Lg wave is important to discriminating earthquakes from explosions by comparing its amplitude and waveform to those of Pg and Pn waves. Lateral variations in crustal structure, including variations in crustal thickness, intrinsic attenuation, and scattering, affect the efficiency of Lg propagation and its consistency as a source discriminant at regional (200-1500 km) distances. To investigate the effects of laterally varying Earth structure on the efficiency of propagation of Lg and Pg, we apply a radiative transport algorithm to model complete, high-frequency (2-4 Hz), regional coda envelopes. The algorithm propagates packets of energy with ray theory through large-scale 3-D structure, and includes stochastic effects of multiple-scattering by small-scale heterogeneities within the large-scale structure. Source-radiation patterns are described by moment tensors. Seismograms of explosion and earthquake sources are synthesized in canonical models to predict effects on waveforms of paths crossing regions of crustal thinning (pull-apart basins and ocean/continent transitions) and thickening (collisional mountain belts), For paths crossing crustal thinning regions, Lg is amplified at receivers within the thinned region but strongly disrupted and attenuated at receivers beyond the thinned region. For paths crossing regions of crustal thickening, Lg amplitude is attenuated at receivers within the thickened region, but experiences little or no reduction in amplitude at receivers beyond the thickened region. The length of the Lg propagation within a thickened region and the complexity of over- and under-thrust crustal layers, can produce localized zones of Lg amplification or attenuation. Regions of intense scattering within laterally homogeneous models of the crust increase Lg attenuation but do not disrupt its coda shape.

  20. Radioimmunoassays for lg classes G, A, M, D, and E in spinal fluids: normal values of different age groups

    International Nuclear Information System (INIS)

    Nerenberg, S.T.; Prasad, R.

    1975-01-01

    Radioimmunoassay procedures of sufficient sensitivity (lgG, 0.5 μg per 100 μl; lgA, 25.0 ng. per 100 μl; lgM, 10.0 ng. per 100 μl; lgD, 0.5 U.* per 100 μl; and lgE, 1.0 U.* per 100 μl) were developed to detect and quantitate all 5 immunoglobulin classes in the cerebrospinal fluid on small aliquots (1 ml.) of unconcentrated cerebrospinal fluid. All 5 immunoglobulin classes were routinely detected in normal individuals for the first time, the levels varying with different age groups for lgG and A but not for the remaining immunoglobulin classes. Race and sex had no effect. Standardization of techniques and establishment of normal values for different age groups sets the stage for determination of immunoglobulin changes related to central nervous system disease

    As metal-oxide-semiconductor field-effect transistors (MOSFET) channel lengths (Lg) are scaled to lengths shorter than Lg<8 nm source-drain tunneling starts to become a major performance limiting factor. In this scenario a heavier transport mass can be used to limit source-drain (S-D) tunneling. Taking InAs and Si as examples, it is shown that different heavier transport masses can be engineered using strain and crystal orientation engineering. Full-band extended device atomistic quantum transport simulations are performed for nanowire MOSFETs at Lg<8 nm in both ballistic and incoherent scattering regimes. In conclusion, a heavier transport mass can indeed be advantageous in improving ON state currents in ultra scaled nanowire MOSFETs.

  8. Jackson, Todd, and the concept of "discharge" in epilepsy.

    Science.gov (United States)

    Reynolds, Edward H

    2007-11-01

    To explore the historical origins of the modern concept of electrical discharges in the brain in epilepsy. I have examined the writings of Hughlings Jackson (1835-1911) and Robert Bentley Todd (1809-1860), especially their Lumleian Lectures on convulsive disorders to the Royal College of Physicians of 1890 and 1849, respectively; and also the influence of Herbert Spencer (1820-1903) on the former and Michael Faraday (1791-1867) on the latter. Contrary to the widely taught view that Jackson was the first to propose electrical discharges in epilepsy it is clear that the discharges suggested by Jackson, influenced by the evolutionary philosopher, Herbert Spencer, were chemical, based on katabolism and anabolism. Jackson had no understanding or proposal based on physics or electricity. On the other hand, Todd had earlier proposed and described electrical concepts of discharges in epilepsy, influenced by his contemporary and colleague in London, Michael Faraday, who at the time was laying the foundations of our modern understanding of electricity and magnetism. Todd and Faraday saw "nervous polarity" as another polar force interchangeable with the polar forces of electricity and magnetism.

  11. Depth of the base of the Jackson aquifer, based on geophysical exploration, southern Jackson Hole, Wyoming, USA

    Science.gov (United States)

    Nolan, Bernard T.; Campbell, David L.; Senterfit, Robert M.

    A geophysical survey was conducted to determine the depth of the base of the water-table aquifer in the southern part of Jackson Hole, Wyoming, USA. Audio-magnetotellurics (AMT) measurements at 77 sites in the study area yielded electrical-resistivity logs of the subsurface, and these were used to infer lithologic changes with depth. A 100-600ohm-m geoelectric layer, designated the Jackson aquifer, was used to represent surficial saturated, unconsolidated deposits of Quaternary age. The median depth of the base of the Jackson aquifer is estimated to be 200ft (61m), based on 62 sites that had sufficient resistivity data. AMT-measured values were kriged to predict the depth to the base of the aquifer throughout the southern part of Jackson Hole. Contour maps of the kriging predictions indicate that the depth of the base of the Jackson aquifer is shallow in the central part of the study area near the East and West Gros Ventre Buttes, deeper in the west near the Teton fault system, and shallow at the southern edge of Jackson Hole. Predicted, contoured depths range from 100ft (30m) in the south, near the confluences of Spring Creek and Flat Creek with the Snake River, to 700ft (210m) in the west, near the town of Wilson, Wyoming.

  14. Pleistocene glaciation of the Jackson Hole area, Wyoming

    Science.gov (United States)

    Pierce, Kenneth L.; Licciardi, Joseph M.; Good, John M.; Jaworowski, Cheryl

    2018-01-24

    Pleistocene glaciations and late Cenozoic offset on the Teton fault have played central roles in shaping the scenic landscapes of the Teton Range and Jackson Hole area in Wyoming. The Teton Range harbored a system of mountain-valley glaciers that produced the striking geomorphic features in these mountains. However, the comparatively much larger southern sector of the Greater Yellowstone glacial system (GYGS) is responsible for creating the more expansive glacial landforms and deposits that dominate Jackson Hole. The glacial history is also inextricably associated with the Yellowstone hotspot, which caused two conditions that have fostered extensive glaciation: (1) uplift and consequent cold temperatures in greater Yellowstone; and (2) the lowland track of the hotspot (eastern Snake River Plain) that funneled moisture to the Yellowstone Plateau and the Yellowstone Crescent of High Terrain (YCHT).The penultimate (Bull Lake) glaciation filled all of Jackson Hole with glacial ice. Granitic boulders on moraines beyond the south end of Jackson Hole have cosmogenic 10Be exposure ages of ~150 thousand years ago (ka) and correlate with Marine Isotope Stage 6. A thick loess mantle subdues the topography of Bull Lake moraines and caps Bull Lake outwash terraces with a reddish buried soil near the base of the loess having a Bk horizon that extends down into the outwash gravel. The Bull Lake glaciation of Jackson Hole extended 48 kilometers (km) farther south than the Pinedale, representing the largest separation of these two glacial positions in the Western United States. The Bull Lake is also more extensive than the Pinedale on the west (22 km) and southwest (23 km) margins of the GYGS but not on the north and east. This pattern is explained by uplift and subsidence on the leading and trailing “bow-wave” of the YCHT, respectively.During the last (Pinedale) glaciation, mountain-valley glaciers of the Teton Range extended to the western edge of Jackson Hole and built

  15. Teleseismic Lg of Semipalatinsk and Novaya Zemlya Nuclear Explosions Recorded by the GRF (Gräfenberg) Array: Comparison with Regional Lg (BRV) and their Potential for Accurate Yield Estimation

    Science.gov (United States)

    Schlittenhardt, J.

    - A comparison of regional and teleseismic log rms (root-mean-square) Lg amplitude measurements have been made for 14 underground nuclear explosions from the East Kazakh test site recorded both by the BRV (Borovoye) station in Kazakhstan and the GRF (Gräfenberg) array in Germany. The log rms Lg amplitudes observed at the BRV regional station at a distance of 690km and at the teleseismic GRF array at a distance exceeding 4700km show very similar relative values (standard deviation 0.048 magnitude units) for underground explosions of different sizes at the Shagan River test site. This result as well as the comparison of BRV rms Lg magnitudes (which were calculated from the log rms amplitudes using an appropriate calibration) with magnitude determinations for P waves of global seismic networks (standard deviation 0.054 magnitude units) point to a high precision in estimating the relative source sizes of explosions from Lg-based single station data. Similar results were also obtained by other investigators (Patton, 1988; Ringdaletal., 1992) using Lg data from different stations at different distances.Additionally, GRF log rms Lg and P-coda amplitude measurements were made for a larger data set from Novaya Zemlya and East Kazakh explosions, which were supplemented with mb(Lg) amplitude measurements using a modified version of Nuttli's (1973, 1986a) method. From this test of the relative performance of the three different magnitude scales, it was found that the Lg and P-coda based magnitudes performed equally well, whereas the modified Nuttli mb(Lg) magnitudes show greater scatter when compared to the worldwide mb reference magnitudes. Whether this result indicates that the rms amplitude measurements are superior to the zero-to-peak amplitude measurement of a single cycle used for the modified Nuttli method, however, cannot be finally assessed, since the calculated mb(Lg) magnitudes are only preliminary until appropriate attenuation corrections are available for the

  18. PCR-based karyotyping of Anopheles gambiae inversion 2Rj identifies the BAMAKO chromosomal form

    Directory of Open Access Journals (Sweden)

    Conway David J

    2007-10-01

    Full Text Available Abstract Background The malaria vector Anopheles gambiae is polymorphic for chromosomal inversions on the right arm of chromosome 2 that segregate nonrandomly between assortatively mating populations in West Africa. One such inversion, 2Rj, is associated with the BAMAKO chromosomal form endemic to southern Mali and northern Guinea Conakry near the Niger River. Although it exploits a unique ecology and both molecular and chromosomal data suggest reduced gene flow between BAMAKO and other A. gambiae populations, no molecular markers exist to identify this form. Methods To facilitate study of the BAMAKO form, a PCR assay for molecular karyotyping of 2Rj was developed based on sequences at the breakpoint junctions. The assay was extensively validated using more than 700 field specimens whose karyotypes were determined in parallel by cytogenetic and molecular methods. As inversion 2Rj also occurs in SAVANNA populations outside the geographic range of BAMAKO, samples were tested from Senegal, Cameroon and western Guinea Conakry as well as from Mali. Results In southern Mali, where 2Rj polymorphism in SAVANNA populations was very low and most of the 2Rj homozygotes were found in BAMAKO karyotypes, the molecular and cytogenetic methods were almost perfectly congruent. Elsewhere agreement between the methods was much poorer, as the molecular assay frequently misclassified 2Rj heterozygotes as 2R+j standard homozygotes. Conclusion Molecular karyotyping of 2Rj is robust and accurate on 2R+j standard and 2Rj inverted homozygotes. Therefore, the proposed approach overcomes the lack of a rapid tool for identifying the BAMAKO form across developmental stages and sexes, and opens new perspectives for the study of BAMAKO ecology and behaviour. On the other hand, the method should not be applied for molecular karyotyping of j-carriers within the SAVANNA chromosomal form.

  2. The LG-bank control concept: An improved method for PWR load-following operation

    International Nuclear Information System (INIS)

    Park, Won Seok; Christenson, J.M.

    1990-01-01

    In this paper the authors present the results of an investigation of a new pressurized water reactor load-following control concept that utilizes light gray (LG) banks in combination with a single high-worth bank. The investigation determined a control strategy and a set of nuclear design parameters for the control banks that permits unrestricted load-following operation over a wide power range at both beginning-of-cycle and end-of-cycle conditions. Advantages of the LG-bank control concept are that flexible load-following maneuvers can be performed without either making changes in the boron concentration or requiring the continuous insertion of a high-worth control bank. These features remove both of the disadvantages of current gray-bank load-following designs, which generally require the continuous insertion of a high-worth bank and in some cases also involve changes in the boron concentration

    1991-07-01

    CT scans of muscles in patients with limb girdle type (LG), myotonic type (MYD) and Duchenne type (DMD) dystrophies were obtained at five different body levels: the neck, L3 vertebral body, pelvic girdle, thigh and lower leg. CT numbers, cross sectional areas (CSA) and %CSA of muscle or fat were evaluated in each muscle. The characteristic CT patterns for each type of muscular dystrophy were obtained. Compared with DMD, the gracilis and soleus were more severely damaged in LG and the biceps femoris remained relatively preserved among the hamstrings. In addition, the multifidus of the neck and sternocleidomastoid also were more severely damaged in MYD. This study suggests that CT scan will be useful in the differential diagnosis of these types of muscular dystrophy as well as in planning appropriate rehabilitation and detecting damaged muscles.

    Full Text Available This paper presents an empirical investigation to study the effects of different strategies including attribute, advantage, application, consumer, competitive advantage, pricing/quality and category on brand promise for products of LG Company in city of Tehran, Iran. The study designs two questionnaires, one for strategic positioning and the other for brand promise in Likert scale. Cronbach alphas for brand promise and strategic positioning are 0.81 and 0.79, respectively. The questionnaires are distributed among 385 randomly selected regular users of LG products and using Spearman correlation as well as Stepwise regression techniques, the effects of various strategies on brand promise are examined. The results of the implementation of Spearman correlation have indicated that there were positive and meaningful relationships between different strategies and brand promise. In addition, the results of Stepwise regression have indicated that three strategies of price/quality, consumer and application were the most important predictors of brand promise.

    2017-09-01

    Full Text Available Biofilm formation by opportunistic pathogens serves as one of the major causes of chronic and persistent infections. Bacterial cells in the biofilms are embedded in their self-generated protective extracellular polymeric substances (EPS, which include exopolysaccharides, large adhesin proteins and extracellular DNA. In this study, we identified an antimicrobial peptide (AMP LG21 that is able to interact specifically with the Psl exopolysaccharide of Pseudomonas aeruginosa, thus it can be used as a diagnostic tool for P. aeruginosa biofilms. Molecular dynamics simulation analysis showed that residues numbered from 15 to 21 (WKRKRFG in LG21 are involved in interacting with Psl. Our study indicates that host immune systems might detect and interact with microbial biofilms through AMPs. Engineering biofilm EPS-targeting AMPs might provide novel strategies for biofilm detection and treatment.

  6. Watertightness in anti-flotation slabs: MIS-RJ case

    Directory of Open Access Journals (Sweden)

    C. Britez

    Full Text Available It is common in coastal cities as Rio de Janeiro, that buildings located close to the shoreline have their basements below water table level. In most cases, the engineering solution for these buildings is to design a massive anti-flotation slab to satisfy, principally, the issues related to structural dimensioning and calculation hypothesis. On the other hand, the execution of this solution imply in significant construction problems related to reinforced concrete watertightness and durability. This paper presents a case study about challenges and solutions devised to execute an anti-flotation, 1m thick, 1200m³ reinforced concrete slab for the new Museu de Imagem e Som (MIS - Sound and Image Museum, located at 50m from the seashore, at Copacabana in Rio de Janeiro, RJ. The results show that concrete proportions, concreting plan and pouring method adopted were decisive in obtaining a watertight structure, avoiding thus the employment of traditional waterproofing alternatives.

    For this paper, we have selected only dwarf galaxies that are located within the zero surface velocity of the LG (~1 Mpc; e.g., van den Bergh 2000, The Galaxies of the Local Group (Cambridge: Cambridge Univ. Press) ; McConnachie 2012, J/AJ/144/4). This definition excludes some dwarfs that have been historically associated with the LG, such as GR8 and IC 5152, but which are located well beyond 1 Mpc. We have chosen to include two galaxies with WFPC2 imaging that are located on the periphery of the LG (Sex A and Sex B), because of their ambiguous association with the LG, the NGC 3109 sub-group, or perhaps neither (although see Bellazzini et al. 2013A&A...559L..11B for discussion of the possible association of these systems). We measured the SFH of each field using the maximum likelihood CMD fitting routine, MATCH (Dolphin 2002MNRAS.332...91D). Briefly, MATCH works as follows: it accepts a range of input parameters (e.g., initial mass function (IMF) slope, binary fraction, age and metallicity bin widths, etc.), uses these parameters to construct synthetic CMDs of simple stellar populations (SSPs), and then linearly combines them with a model foreground CMD to form a composite model CMD with a complex SFH. The composite model CMD is then convolved with the noise model from the artificial star tests (i.e., completeness, photometric uncertainties, and color/magnitude biases). The resulting model CMD is then compared to the observed CMD using a Poisson likelihood statistic. (3 data files).

    2009-12-01

    Jackson, Michigan, is a medium-sized city suffering from a bad economy and obesity-related health issues. Nearly 20% of the 36,000 residents live below the poverty line. It is a relatively young city (median age of 30 years) with a mixed ethnicity (20% black, 73% white, 4% Hispanic). The city offers many structured, active recreational opportunities, but has not integrated physical activity into daily life. Project U-Turn aimed to increase active transportation (e.g., biking, walking, and transit use) through an integrated approach to Active Living by Design's community action model and the Michigan Safe Routes to School model. Resources were focused on active living promotions and programs; partnership meetings were the source of changes in policy and physical projects. Each initiative was designed to introduce each of the 5Ps (preparation, promotion, programs, policy, and physical projects) to build support for the partnership's overall work. The partnership collected snapshot data of community walking and biking behavior, percentage of students walking to school, participation in events and programs, and new physical projects. Jackson saw a vast improvement in physical infrastructure and policy and a related increase in walking and biking in the community. The project engaged in purposeful partnership building to implement effective programs and promotions that built support for policy and physical projects. Limited resources were best used by encouraging partners to contribute and coordinate activities using existing staff, funding, and resources. Jackson has seen a shift toward awareness of the benefits of active living on community health, economic development, and environmental awareness.

    Jackson, Murray

    2011-04-01

    Murray Jackson was among the early trainees at the Society of Analytical Psychology (SAP) drawn to Jungian ideas during the 1950s when the training was still relatively informal. He was born in Australia where he became a doctor and came to London to study psychiatry with a particular interest in psychosis. He was influenced by Michael Fordham with whom he had an analysis and his four papers, published in the Journal of Analytical Psychology in the early 1960s, contributed significantly to the growing interest in clinical technique, particularly transference, that developed in the Society at that time. Later, he retrained at the British Institute of Psychoanalysis in the Kleinian tradition and was the first consultant at the Maudsley Hospital to run a 10-bed unit for severely mentally ill patients applying psychoanalytic principles. In April 2010, Jan Wiener interviewed Murray Jackson in France, where he now lives in retirement, about his interest and subsequent disappointment in Jungian ideas as well as his involvement with the Society of Analytical Psychology at a particular point in its history. After a brief introduction, the interview is reproduced in full. © 2011, The Society of Analytical Psychology.

    Full Text Available Building Collaborative Health Promotion Partnerships: The Jackson Heart Study. Background: Building a collaborative health promotion partnership that effectively employs principles of community-based participatory research (CBPR involves many dimensions. To ensure that changes would be long-lasting, it is imperative that partnerships be configured to include groups of diverse community representatives who can develop a vision for long-term change. This project sought to enumerate processes used by the Jackson Heart Study (JHS Community Outreach Center (CORC to create strong, viable partnerships that produce lasting change. Methods: JHS CORC joined with community representatives to initiate programs that evolved into comprehensive strategies for addressing health disparities and the high prevalence of cardiovascular disease (CVD. This collaboration was made possible by first promoting an understanding of the need for combined effort, the desire to interact with other community partners, and the vision to establish an effective governance structure. Results: The partnership between JHS CORC and the community has empowered and inspired community members to provide leadership to other health promotion projects. Conclusion: Academic institutions must reach out to local community groups and together address local health issues that affect the community. When a community understands the need for change to respond to negative health conditions, formalizing this type of collaboration is a step in the right direction.

    Full Text Available Purpose: The main objective of this paper is to determine the annual cyclical flight delays at Hartsfield-Jackson Atlanta International Airport. Then using other data such as annual precipitation, passenger and aircraft traffic volumes and other factors, we attempted to correlate these factors with overall delays. These data could assist airport management in predicting periods of flight delay.Design/methodology/approach: Data were taken and analyzed from the data base “Research and Innovation Technology Administration” (RITA for the years 2005-2011 for Hartsfield-Jackson Atlanta International Airport. The data included 2.8 million flights originating and departing from this airport. Data were also gathered from the National Oceanic and Atmospheric Administration (NOAA showing precipitation. Additional data were gathered from the FAA regarding delay causes, number and types of delays and changes to the infrastructure of ATL airportFindings: There is a repeatable annual pattern of delays at ATL that can be modeled using delay data from the Bureau of Transportation Statistics. This pattern appears to be caused primarily by the frequency and amount of precipitation that falls at ATL and by the amount of flights that arrive and depart at ATL.Originality/value: This information could assist airport operations personnel, FAA air traffic controllers and airlines in anticipating and mitigating delays at specific times of the year.

  20. Revisiting Johnson and Jackson boundary conditions for granular flows

    Energy Technology Data Exchange (ETDEWEB)

    Li, Tingwen; Benyahia, Sofiane

    2012-07-01

    In this article, we revisit Johnson and Jackson boundary conditions for granular flows. The oblique collision between a particle and a flat wall is analyzed by adopting the classic rigid-body theory and a more realistic semianalytical model. Based on the kinetic granular theory, the input parameter for the partial-slip boundary conditions, specularity coefficient, which is not measurable in experiments, is then interpreted as a function of the particle-wall restitution coefficient, the frictional coefficient, and the normalized slip velocity at the wall. An analytical expression for the specularity coefficient is suggested for a flat, frictional surface with a low frictional coefficient. The procedure for determining the specularity coefficient for a more general problem is outlined, and a working approximation is provided.

    This article offers reflections on the article "Bystander Training as Leadership Training: Notes on the Origins, Philosophy and Pedagogy of the Mentors in Violence Prevention Model" by Jackson Katz in this issue of Violence Against Women. The authors rely on their unique perspectives in varying roles at the University of California (UC) Berkeley, as well as on relevant social science and social justice research. The article explores five themes of violence prevention and anti-oppression work: leadership, social justice, gender identity, issues of identity and status, and diffusion of innovation. Through these five themes, the authors acknowledge Mentors for Violence Prevention's (MVP) successes while critically analyzing opportunities for a more comprehensive approach to violence prevention.

Wind induced upwelling events are frequently observed in the area during summer, becoming rare during winter. By the summer cruise a bloom of phytoplankton was observed in surface, close to the coast, with chlorophyll concentrations reaching 25.55 mg Chl-a m-3, uncoupled from the cold, nutrient rich waters of South Atlantic Central Water (SACW, found below 40 m depth. During the winter cruise, the SACW raised at the surface waters in front of Cabo Frio depicting an upwelling event. However, in spite of high surface nitrate concentrations (up to 7.7 f.1M chlorophyll-a were lower than 2 mg Chl-a m-3. The phytoplankton biomass, meteorological and hydrological data suggest a probable upwelling event immediately before the summer cruise, and an ongoing one during winter time. Cluster analyses and principal component analyses (PCA were applied to summer and winter data, pointing out multidimensional fronts in the area during both seasons.A biomassa fitoplanctônica, parâmetros químicos e hidrologia foram estudadas em um transecto de 101,6 Km ao largo de Cabo Frio, (RJ Brasil, durante o verão (Dezembro 29 a 31, 1991 e inverno (Junho 27 a 30, 1992.

    Severe offset saturation results from the passage of direct current through power transformers. Such direct current can arise from geomagnetic disturbances, or resistive coupling of the substation ground to HVDC earth electrodes. This paper documents the development of alternative approaches for the design and application of blocking devices placed between transformer neutrals and the substation ground. System constraints on the impedance and overvoltage limitation of the neutral blocking device (NBD) are covered. Three alternative NBD schemes are developed and optimized. System performance of the NBD is discussed, as are the practical implementation considerations for this unconventional equipment application. Although the paper focuses on the NBD requirements of Hydro-Quebec's Radisson/LG2 complex, the fundamental information is applicable to any situation where dc must be clocked from a power transformer neutral in a system designed for effectively-grounded operation

    Full Text Available Abstract Background Investigation of the expression of an intestinal stem cell marker in esophageal adenocarcinomas (EAC with and without Barrett's Esophagus (BE, with respect to a cancer stem cell (CSC hypothesis. Materials and methods Expression of a putative intestinal stem cell marker LgR5 was analyzed in esophageal cancer specimen (n = 70: 41 EAC with BE, 19 EAC without BE, and n = 10 esophageal squamous-cell carcinomas, ESCC and in the adenocarcinoma cell line OE-33. Ki-67 and Cdx-2 were co-labelled with LgR5 in double staining experiments. Immunhistochemical expression results were confirmed by RT-PCR and correlated with tumor stage and five-year survival rates. Results LgR5was found expressed in 35 of 41 (85% EAC with BE and in 16 of 19 (81% EAC without BE. By contrast, LgR5 was not found to be expressed in ESCC. Quantification of immunolabeling showed 15% LgR5+ cells in EAC with BE, 32% LgR5+ cells in adjacent BE and 13% in EAC without BE. Immunofluorescence double staining experiments with LgR5 and Ki-67 revealed a subpopulation (~5% of proliferating LgR+/Ki-67+ cells. On mRNA-level, expression of LgR5 was higher in BE in comparison to EAC (p = 0.0159. High levels of LgR5 expression in BE associated EAC were associated with poorer survival in univariate analysis. Conclusion The stem cell marker LgR5 is expressed in EAC, irrespective of association with BE, and appears to have negative impact on survival. The subset of proliferating LgR5+ cells (

  5. Large geometry secondary ion mass spectrometry (LG-SIMS) for the enhancement of nuclear safeguards applications

    2013-01-01

    A new LG-SIMS (Large Geometry Secondary Ion Mass Spectrometry) laboratory is currently being established at the Joint Research Centre, the Institute of Transuranium Elements for the purpose of improving the analytical capabilities within the European Commission. The laboratory will mainly be used for analysing uranium bearing aerosol particles collected on cotton swipes from nuclear Safeguards inspections but it will also be used for Nuclear Forensics and other Safeguards related applications. Until recently, this type of analysis has predominantly been performed using the small geometry CAMECA IMS 3F-7F instrument series. These instruments provide both particle screening and isotope ratio capabilities. The performance of these instruments was however limited by the occurrence of isobaric interferences, in particular for the minor isotopes ( 234 U, 236 U), that could not be resolved without compromising the transmission of the instrument. A recent breakthrough to solve this problem has been the implementation of Large Geometry SIMS, the CAMECA 1270 / 1280 / 1280-HR models, for this type of analysis. This instrument has originally been developed for geosciences applications requiring both high transmission and high mass resolution capabilities. This came out to be a key instrumental advantage also for uranium particle analyses, as it allows efficient removal of common molecular interferences with minimum loss in transmission. Furthermore an electrostatic ion optical device has been added for increasing the mass dispersion which allows the simultaneous detection of all uranium isotopes. The Automated Particle Measurement (APM) software has been developed to perform screening measurement in an automated mode. Combined with the APM screening software, LG-SIMS instruments greatly improve the overall performance and throughput of isotopic analyses of U particles for nuclear Safeguards purposes. The paper is followed by the slides of the presentation. (A.C.)

  6. Hughlings Jackson and the "doctrine of concomitance": mind-brain theorising between metaphysics and the clinic.

    John Hughlings Jackson (1835-1911) is a major figure at the origins of neurology and neuroscience in Britain. Alongside his contributions to clinical medicine, he left a large corpus of writing on localisation of function in the nervous system and other theoretical topics. In this paper I focus on Jackson's "doctrine of concomitance"-his parallelist theory of the mind-brain relationship. I argue that the doctrine can be given both an ontological and a causal interpretation, and that the causal aspect of the doctrine is especially significant for Jackson and his contemporaries. I interpret Jackson's engagement with the metaphysics of mind as an instance of what I call meta-science-the deployment by scientists of metaphysical positions and arguments which help streamline empirical investigations by bracketing off unanswerable questions and focussing attention on matters amenable to the current tools of experimental research.

    Full Text Available Este artigo analisou a desigualdade ambiental em Rio das Ostras-RJ por meio do mapeamento das condições adequadas de habitação, baseada nos índices de abastecimento de água, de esgotamento sanitário, de alfabetização, de renda, de disposição do lixo e de presença de vegetação, oriundos do Censo IBGE de 2010 e de imagens de satélite Cbers-2b e Landsat-5, de 2008. Os índices foram ponderados pelo método Analitic Hierarchy Process e agregados no software ArcGis 10.0, construindo o índice de desigualdade ambiental. O município de Rio das Ostras foi selecionado por apresentar um elevado crescimento populacional entre 2000 e 2010, seguido de um significativo crescimento econômico derivado da exploração de petróleo e gás na Bacia de Campos. Nesse sentido, tornou-se importante verificar se o crescimento populacional e econômico vinha acompanhando de condições de habitação adequadas para toda a população. O resultado expôs a presença de desigualdade ambiental em Rio das Ostras, afetando principalmente a população de menor renda, com maiores porcentagens de analfabetos e localizados no limite da área urbanizada e na área rural, cujas áreas apresentaram deficiência na oferta de serviços e infraestrutura. Concluiu-se que a distribuição condições adequadas de habitação avaliada por este trabalho não é homogênea e segue a lógica de valorização da terra urbana para o processo de especulação imobiliária em Rio das Ostras. A presença da desigualdade ambiental também representa dificuldades na garantia da sustentabilidade urbana, com diversas áreas desprovidas de condições de habitação em que, por isso, acabam por impactar o meio ambiente.

  9. Genetic characterization of plasmid pRJ5 of Staphylococcus aureus compared to plasmid pE194

    1993-01-01

    The pRJ5, a naturally occurring constitutive macrolide, lincosamide and streptogramin B (MLS) resistance plasmid of Staphylococcus aureus, was compared to pE194, a plasmid that confers the inducible phenotype. pRJ5 was stable in all strains of S. aureus tested, even under growth at 43 O C, which distinguished it from pE194 which was shown to be thermo-sensitive for replication. pRJ5, like pE194, was highly unstable in Bacillus subtilis when the cells were grown in nonselective conditions. Multimeric forms of pRJ5 DNA were detected in the few cells of B. subtilis that retained this plasmid. pE194 was transduced by phages φ 11 and φ 443 at frequencies 400 and 20-fold higher, respectively, than pRJ5. Both plasmids were co-transduced with the plasmid pRJ4. pRJ5 was shown to be compatible with pE194. Therefore they belong to distinct Inc groups. Hybridization studies revealed that pRJ5 shares a 1.35 kb region of homology to pE194, which is limited to the erm gene, conferring MLS resistance. (author)

    After a brief medical career, Charles Thomas Jackson (1805-1880) began work as a consulting chemist and geologist in Boston. He serves as State Geologist in Maine, Rhode Island, and New Hampshire from 1837 to 1884, and completed geological surveys of those States. In 1847, he was appointed United States Geologist to undertake a survey of the public lands of the Lake Superior region of Michigan. This survey was beset by strife, and Jackson was forced to resign in 1849. -from Author

  12. Eocene Yegua Formation (Claiborne group) and Jackson group lignite deposits of Texas

    The lignite deposits within the upper Eocene Yegua Formation (Claiborne Group) and the overlying Jackson Group are among the coal resources that were not quantitatively assessed as part of the U.S. Geological Survey's (USGS) National Coal Resource Assessment (NCRA) program in the Gulf Coastal Plain coal province. In the past, these lignite-bearing stratigraphic units often have been evaluated together because of their geographic and stratigraphic proximity (Fisher, 1963; Kaiser, 1974; Kaiser et al., 1980; Jackson and Garner, 1982; Kaiser, 1996) (Figures 1, 2). The term “Yegua-Jackson trend“ is used informally herein for the lignite-bearing outcrops of these Late Eocene deposits in Texas. Lignite beds in the Yegua-Jackson trend generally are higher both in ash yield and sulfur content than those of the underlying Wilcox Group (Figure 2). Recent studies (Senkayi et al., 1987; Ruppert et al., 1994; Warwick et al., 1996, 1997) have shown that some lignite beds within the Yegua-Jackson trend contain partings of volcanic ash and host elevated levels of trace elements that have been identified as potentially hazardous air pollutants (HAPs) in the United States Clean Air Amendments of 1990. Lignite beds within the Yegua Formation are thin (less than or equal to 6 ft) and laterally discontinuous in comparison with most Wilcox Group deposits (Ayers, 1989a); in contrast, the Jackson Group lignite beds range up to 12 ft in total thickness and are relatively continuous laterally, extending nearly 32 mi along strike.

    This study examined interindividual personality differences between Port Jackson sharks Heterodontus portusjacksoni utilizing a standard boldness assay. Additionally, the correlation between differences in individual boldness and stress reactivity was examined, exploring indications of individual coping styles. Heterodontus portusjacksoni demonstrated highly repeatable individual differences in boldness and stress reactivity. Individual boldness scores were highly repeatable across four trials such that individuals that were the fastest to emerge in the first trial were also the fastest to emerge in subsequent trials. Additionally, individuals that were the most reactive to a handling stressor in the first trial were also the most reactive in a second trial. The strong link between boldness and stress response commonly found in teleosts was also evident in this study, providing evidence of proactive-reactive coping styles in H. portusjacksoni. These results demonstrate the presence of individual personality differences in sharks for the first time. Understanding how personality influences variation in elasmobranch behaviour such as prey choice, habitat use and activity levels is critical to better managing these top predators which play important ecological roles in marine ecosystems. © 2016 The Fisheries Society of the British Isles.

  14. On Murray Jackson's 1961 'Chair, couch and countertransference'.

    Science.gov (United States)

    2015-09-01

    One of the problems facing psychoanalysts of all schools is that theory has evolved at a much faster pace than practice. Whereas there has been an explosion of theory, practice has remained, at least officially, static and unchanging. It is in this sense that Murray Jackson's 1961 paper is still relevant today. Despite the rise of the new relational and intersubjective paradigms, most psychoanalysts, and not a few Jungian analysts, still seem to feel that the couch is an essential component of the analytical setting and process. If the use of the couch is usually justified by the argument that it favours regression, facilitates analytical reverie and protects the patient from the influence of the analyst, over time many important psychoanalysts have come to challenge this position. Increasingly these analysts suggest that the use of the couch may actually be incompatible with the newer theoretical models. This contention is strengthened by some of the findings coming from the neurosciences and infant research. This underlines the necessity of empirical research to verify the clinical effectiveness of these different positions, couch or face-to-face, but it is exactly this type of research that is lacking. © 2015, The Society of Analytical Psychology.

    The objective of this study was to standardize The Scale of Motivation in Sports in Mexican athletes. It was necessary to get the original version which, as it was in French, had to be traslated into Spanish. Semantics and composition were also revised. In the first study the items discrimination was analysed by means of cross validation, the inner consistency made through Alpha of Cronbach (.8936. In the normative study all items discriminated and fiability was .8468. The analysis of the factors, which were distributed in a different way from that of the original scale. With the obtention of percentile norms the future assessment and diagnosis of Mexican athletes will be valid and can be trusted. A standardization with different population is suggested.
    KEY WORDS: Scale, motivation, sports, Mexican athletes.

    Cycloastragenol (CA), an exclusive telomerase activator, was derived from the Astragali Radix which is widely distributed in Turkey. Until now, there is no report to produce CA with effective and environment-friendly methods. Biotransformation is considered to be a promising technology. Thus, the present study was aimed to establish a biotransformation technology that could efficiently produce CA. In this paper, a microorganism, LG-502, was used to successfully transform astragaloside IV (ASI) to CA by analysis of thin layer chromatography (TLC) and high-performance liquid chromatography (HPLC). The phylogenetic analysis of the 16S rRNA indicated that this strain belongs to Bacillus sp. Three metabolites were separated during the fermentation and characterized to be cyclogaleginoside B, CA, and 20R, 24S-epoxy-6α, 16β, 25-trihydroxy-9, 19-cycloartan-3-one based on NMR and MS spectroscopic analyses. The conversion rate of ASI and yield rate of CA were achieved as high as 89 and 84%, respectively, under optimized conditions. Enzymatic analysis showed that the glycosidases were mainly located inside the bacterial body, and the activities of glucosidases were much higher than the xylosidases under the experimental conditions. This study provides a feasible, effective, and eco-friendly way to prepare CA from ASI, which might greatly contribute to the applications of ASI.

  1. James Taylor (1859-1946): favourite disciple of Hughlings Jackson and William Gowers.

    In neurological circles today the name James Taylor (1859-1946) is probably remembered mainly for his role in editing the Selected Writings of John Hughlings Jackson, the most readily available source of Jackson's contributions to neurological knowledge. Taylors' own neurological achievements are largely or entirely forgotten, but in his day he was an influential figure whose career linked the great figures of the golden era of late nineteenth century British neurology to the neurology of the first half of the twentieth century. Not only was he a junior professional colleague and close friend of both John Hughlings Jackson and William Gowers, he also produced a substantial corpus of neurological writings in his own right, including a textbook of child neurology and the first English language account of subacute combined degeneration of the spinal cord.

    Full Text Available In this paper we will build a bank model using Poisson measures and Jackson queueing networks. We take into account the relationship between the Poisson and the exponential distributions, and we consider for each credit/deposit type a node where shocks are modeled as the compound Poisson processes. The transmissions of the shocks are modeled as moving between nodes in Jackson queueing networks, the external shocks are modeled as external arrivals, and the absorption of shocks as departures from the network.

    1975-12-01

    The Rorschach protocols of 43 males consecutively admitted to a university outpatient clinic were scored for frequency of the 20 Wheeler signs of homosexuality. Based on case history data, patients were assigned to homosexual, sex-role disturbed, or normal-control groups. In addition to the traditional group comparison the results were analyzed to yield P (Ci/Rj); that is, the probability of criterion group membership given test indicator. Both the homosexual and sex-role disturbed group displayed significantly more Wheeler signs than normals. Furthermore, given a Wheeler sign score of 15%, .75 of the predicted-homosexual group would be correctly classified compared to a .21 baserate prediction. It was suggested that expressing results as P (Ci/Rj) provides information more relevant to the clinician than is provided by the traditional practice of reporting significant differences between groups.

    Patients who have sustained a spinal cord injury remain at risk for further neurologic deterioration until the spine is adequately stabilized. To our knowledge, no study has previously addressed the effects of different bed-to-operating room table transfer techniques on thoracolumbar spinal motion in an instability model. We hypothesized that the conventional logroll technique used to transfer patients from a supine position to a prone position on the operating room table has the potential to confer significantly more motion to the unstable thoracolumbar spine than the Jackson technique. Three-column instability was surgically created at the L1 level in seven cadavers. Two protocols were tested. The manual technique entailed performing a standard logroll of a supine cadaver to a prone position on an operating room Jackson table. The Jackson technique involved sliding the supine cadaver to the Jackson table, securing it to the table, and then rotating it into a prone position. An electromagnetic tracking device measured motion--i.e., angular motion (flexion-extension, lateral bending, and axial rotation) and linear translation (axial, medial-lateral, and anterior-posterior) between T12 and L2. The logroll technique created significantly more motion than the Jackson technique as measured with all six parameters. Manual logroll transfers produced an average of 13.8 degrees to 18.1 degrees of maximum angular displacement and 16.6 to 28.3 mm of maximum linear translation. The Jackson technique resulted in an average of 3.1 degrees to 5.8 degrees of maximum angular displacement (p patient safety. Performing the Jackson turn requires approximately half as many people as required for a manual logroll. This study suggests that the Jackson technique should be considered for supine-to-prone transfer of patients with known or suspected instability of the thoracolumbar spine.

  1. Chancroid detected by polymerase chain reaction--Jackson, Mississippi, 1994-1995.

    Science.gov (United States)

    1995-08-04

    Chancroid is a sexually transmitted disease (STD) caused by infection with Haemophilus ducreyi and is characterized by genital ulceration. Chancroid is underreported in the United States (1), reflecting, in part, difficulties in diagnosis because of clinical similarities between chancroid and other ulcerative STDs. In addition, laboratory confirmation by culture is 53%-84% sensitive and often is unavailable in clinical settings (2). In September 1994, clinicians at the District V STD clinic of the Mississippi State Department of Health (MSDH) in Jackson reported examining patients with genital ulcers characteristic of chancroid but lacked capacity to confirm the diagnosis. To determine the cause of the ulcers, MSDH, in conjunction with CDC, conducted an investigation of all patients with genital ulcers examined at the Jackson STD clinic during October 20, 1994-February 1, 1995. This report summarizes the findings of the investigation.

The fate of the region was sealed when a gigantic land cession was conceded by Native Americans in the Treaty of Fort Jackson. Aug.9, 1814, symbolizes both the end of Native American clout in the Old Southwest and the beginning of a new era in Southern history. Andrew Jackson played a key‑role in this shift in power. Other individuals, but also social groups and entire nations were involved in a complex web of relationships and cultural, political and economic conflicts.

    Full Text Available We investigated whether lactic acid bacteria isolated from gajami sik-hae (GLAB are capable of reducing the intracellular lipid accumulation by downregulating the expression of adipogenesis-related genes in differentiated 3T3-L1 cells. The GLAB, Lactobacillus plantarum LG42, significantly decreased the intracellular triglyceride storage and the glycerol-3-phosphate dehydrogenase (GPDH activity in a dose-dependent manner. mRNA expression of transcription factors like peroxisome proliferator-activated receptor (PPAR γ and CCAAT/enhancer-binding protein (C/EBP α involved in adipogenesis was markedly decreased by the GLAB treatment. Moreover, the GLAB also decreased the expression level of adipogenic markers like adipocyte fatty acid binding protein (aP2, leptin, GPDH, and fatty acid translocase (CD36 significantly. These results suggest that the GLAB inhibits lipid accumulation in the differentiated adipocyte through downregulating the expression of adipogenic transcription factors and other specific genes involved in lipid metabolism.

    Full Text Available ABSTRACT Restingas are extremely degraded, tropical sandy ecosystems and are poorly studied in terms of nutrient cycling. The present study aimed to evaluate litter dynamics in a forest dune at Restinga da Marambaia, RJ. Litterfall was collected monthly using two parallel transects installed 200 m apart from each other with 15 litter traps (0.25 m2, over two consecutive years. The litterfall was sorted into leaves, twigs, flowers, fruits, and refuse. Litter decomposition was evaluated by the ratio between litterfall and litter layer on the soil surface, which was estimated every four months by quadrats (0.25 m2 placed next to the litter traps. The average annual litterfall was low (6.8 t ha-1 year-1 , mostly constituted by leaves (70%, with the greatest deposits occurring during the rainy season. The decomposition rate was low (0.85 and the turnover time was long (439 days. This litter dynamic contributes to the nutrient economy.

    Chest tubes are used in every case of coronary artery bypass grafting (CABG) to evacuate shed blood from around the heart and lungs. This study was designed to assess the effective of Jackson-Pratt drain in compare with conventional chest drains after CABG. This was a randomized controlled trial that conducted on 218 patients in Chamran hospital from February to December 2016. Eligible patients were randomized in a 1:1 ratio. Jackson-Pratt drain group had 109 patients who received a chest tube insertion in the pleural space of the left lung and a Jackson-Pratt drain in mediastinum, and Chest tube drainage group had 109 patients who received double chest tube insertion in the pleural space of the left lung and the mediastinum. The incidence of pleural effusions in Jackson-Pratt drain group and chest tube group were not statistically different. The pain score at 2-h in Drain group was significantly higher than chest tube group ( P = 0.001), but the trend of pain score between groups was not significantly different ( P = 0.097). The frequency of tamponade and atrial fibrillation (AF) were significantly lower in Jackson-Pratt drain group ( P drain is equally effective for preventing cardiac tamponade, pleural effusions, and pain intensity in patients after CABG when compared with conventional chest tubes, but was significantly superior regarding efficacy to hospital and Intensive Care Unit length of stay and the incidence of AF.

To quantify motion in multiple axes created by transfer methods from stretcher to operating table in the prone position in a cervical global instability model. Patients with an unstable cervical spine remain at high risk for further secondary injury until their spine is adequately surgically stabilized. Previous studies have revealed that collars have significant, but limited benefit in preventing cervical motion when manually transferring patients. The literature proposes multiple methods of patient transfer, although no one method has been universally adopted. To date, no study has effectively evaluated the relationship between spine motion and various patient transfer methods to an operating room table for prone positioning. A global instability was surgically created at C5-6 in 4 fresh cadavers with no history of spine pathology. All cadavers were tested both with and without a rigid cervical collar in the intact and unstable state. Three headrest permutations were evaluated Mayfield (SM USA Inc), Prone View (Dupaco, Oceanside, CA), and Foam Pillow (OSI, Union City, CA). A trained group of medical staff performed each of 2 transfer methods: the "manual" and the "Jackson table" transfer. The manual technique entailed performing a standard rotation of the supine patient on a stretcher to the prone position on the operating room table with in-line manual cervical stabilization. The "Jackson" technique involved sliding the supine patient to the Jackson table (OSI, Union City, CA) with manual in-line cervical stabilization, securing them to the table, then initiating the table's lock and turn mechanism and rotating them into a prone position. An electromagnetic tracking device captured angular motion between the C5 and C6 vertebral segments. Repeated measures statistical analysis was performed to evaluate the following conditions: collar use (2 levels), headrest (3 levels), and turning technique (2 levels). For all

    The conditioned place preference (CPP) test is frequently used to evaluate the rewarding properties of drugs of abuse in mice. Despite its widespread use in transgenic and knockout experiments, there are few forward genetic studies using CPP to identify novel genes contributing to drug reward. In this study, we tested LG/J and SM/J inbred strains and the parents/offspring of 10 families of an F(45)/F(46) advanced intercross line (AIL) for methamphetamine-induced CPP (MA-CPP) once per week over 2 weeks. Both LG/J and SM/J mice exhibited significant MA-CPP that was not significantly different between the two strains. Furthermore, LG/J mice showed significantly less acute MA-induced locomotor activity as well as locomotor sensitization following subsequent MA injections. AIL mice (N = 105) segregating LG/J and SM/J alleles also demonstrated significant MA-CPP that was equal in magnitude between the first and second week of training. Importantly, MA-CPP in AIL mice did not correlate with drug-free or MA-induced locomotor activity, indicating that MA-CPP was not confounded by test session activity and implying that MA-CPP is genetically distinct from acute psychomotor sensitivity. We estimated the heritability of MA-CPP and locomotor phenotypes using midparent-offspring regression and maximum likelihood estimates derived from the kinship coefficients of the AIL pedigree. Heritability estimates of MA-CPP were low (0-0.21) and variable (SE = 0-0.33) which reflected our poor power to estimate heritability using only 10 midparent-offspring observations. In sum, we established a short-term protocol for MA-CPP in AIL mice that could reveal LG/J and SM/J alleles important for MA reward. The use of highly recombinant genetic populations like AIL should facilitate the identification of these genes and may have implications for understanding psychostimulant abuse in humans.

    The "Jackson Nursery", existing from February 1937 until March 1938, was directed by Anna Freud and financed by Edith Jackson and Dorothy Burlingham. It took care of infants from the poorest strata of Vienna and also gave material support to their families. On the other hand, it was a training institution for psychoanalysts, offering the opportunity of observing children during their first two years, e. g. their feeding habits and social sense. In addition, the Jackson Nursery was a place for research where psychoanalytic theories of infantile development were checked against the findings of direct observation. The work started here was then continued by A. Freud and D. Burlingham on a larger scale in their War Nurseries.--This paper examines the many-sided activities in the nursery mainly on the basis of unpu blished archival documents.

    Full Text Available Background: Chest tubes are used in every case of coronary artery bypass grafting (CABG to evacuate shed blood from around the heart and lungs. This study was designed to assess the effective of Jackson-Pratt drain in compare with conventional chest drains after CABG. Materials and Methods: This was a randomized controlled trial that conducted on 218 patients in Chamran hospital from February to December 2016. Eligible patients were randomized in a 1:1 ratio. Jackson-Pratt drain group had 109 patients who received a chest tube insertion in the pleural space of the left lung and a Jackson-Pratt drain in mediastinum, and Chest tube drainage group had 109 patients who received double chest tube insertion in the pleural space of the left lung and the mediastinum. Results: The incidence of pleural effusions in Jackson-Pratt drain group and chest tube group were not statistically different. The pain score at 2-h in Drain group was significantly higher than chest tube group (P = 0.001, but the trend of pain score between groups was not significantly different (P = 0.097. The frequency of tamponade and atrial fibrillation (AF were significantly lower in Jackson-Pratt drain group (P < 0.05. Conclusion: The Jackson-Pratt drain is equally effective for preventing cardiac tamponade, pleural effusions, and pain intensity in patients after CABG when compared with conventional chest tubes, but was significantly superior regarding efficacy to hospital and Intensive Care Unit length of stay and the incidence of AF.

    The Jackson Career Explorer (JCE) is a short form and continuous version of the Jackson Vocational Interest Survey measuring 34 vocational interest dimensions which can be reduced to seven factors (six vocational interest factors and one work style factor). Both the scales and factors were examined for possible significant correlations with social desirability and self-monitoring. Volunteer participants ( N = 779) aged 14 to 92 years completed the JCE, a social desirability scale, and a self-monitoring scale. Social desirability did not correlate significantly with the JCE scales and factors. Self-monitoring was found to correlate significantly with only a few of the JCE dimensions, including the performing arts, dominant leadership, and law scales as well as the business factor. Interestingly, the accountability JCE work style scale, which assesses a preference to work in an environment requiring high levels of honesty, had a significant negative correlation with self-monitoring. These results add to the validity of the JCE and add information to the area of vocational interest assessment.

    Importance sampling is a technique that is commonly used to speed up Monte Carlo simulation of rare events. However, little is known regarding the design of efficient importance sampling algorithms in the context of queueing networks. The standard approach, which simulates the system using an a priori fixed change of measure suggested by large deviation analysis, has been shown to fail in even the simplest network settings. Estimating probabilities associated with rare events has been a topic of great importance in queueing theory, and in applied probability at large. In this article, we analyse the performance of an importance sampling estimator for a rare event probability in a Jackson network. This article carries out strict deadlines to a two-node Jackson network with feedback whose arrival and service rates are modulated by an exogenous finite state Markov process. We have estimated the probability of network blocking for various sets of parameters, and also the probability of missing the deadline of customers for different loads and deadlines. We have finally shown that the probability of total population overflow may be affected by various deadline values, service rates and arrival rates.

    Recruitment for large cohort studies is typically challenging, particularly when the pool of potential participants is limited to the descendants of individuals enrolled in a larger, longitudinal "parent" study. The increasing complexity of family structures and dynamics can present challenges for recruitment in offspring. Few best practices exist to guide effective and efficient empirical approaches to participant recruitment. Social and behavioral theories can provide insight into social and cultural contexts influencing individual decision-making and facilitate the development strategies for effective diffusion and marketing of an offspring cohort study. The purpose of this study was to describe the theory-informed recruitment approaches employed by the Jackson Heart KIDS Pilot Study (JHKS), a prospective offspring feasibility study of 200 African American children and grandchildren of the Jackson Heart Study (JHS)-the largest prospective cohort study examining cardiovascular disease among African American adults. Participant recruitment in the JHKS was founded on concepts from three theoretical perspectives-the Diffusion of Innovation Theory, Strength of Weak Ties, and Marketing Theory. Tailored recruitment strategies grounded in participatory strategies allowed us to exceed enrollment goals for JHKS Pilot Study and develop a framework for a statewide study of African American adolescents.

    Jackson State University recently established the Center for Spatial Data Research and Applications, a Geographical Information System (GIS) and remote sensing laboratory. Taking advantage of new technologies and new directions in the spatial (geographic) sciences, JSU is building a Center of Excellence in Spatial Data Management. New opportunities for research, applications, and employment are emerging. GIS requires fundamental shifts and new demands in traditional computer science and geographic training. The Center is not merely another computer lab but is one setting the pace in a new applied frontier. GIS and its associated technologies are discussed. The Center's facilities are described. An ARC/INFO GIS runs on a Vax mainframe, with numerous workstations. Image processing packages include ELAS, LIPS, VICAR, and ERDAS. A host of hardware and software peripheral are used in support. Numerous projects are underway, such as the construction of a Gulf of Mexico environmental data base, development of AI in image processing, a land use dynamics study of metropolitan Jackson, and others. A new academic interdisciplinary program in Spatial Data Management is under development, combining courses in Geography and Computer Science. The broad range of JSU's GIS and remote sensing activities is addressed. The impacts on changing paradigms in the university and in the professional world conclude the discussion.

    Gamma radiation in a set of rooms of the sector D of the Cardeal Leme Building in the Pontifica Universidade Catolica of Rio de Janeiro, and also in some outdoors ares at the PUC/RJ campus, are examined using well established experimental techniques. The exposures were obtained by using CaSO 4 :Dy thermoluminescent dosimeters and one NaI(Tl) crystal associated with a multichannel pulse height analyser to store the gamma ray spectra of the locations chosen for the measurements. Outdoors, the average of the actual readings of exposures rates obtained at PUC/RJ campus remained around 2,5x10 -2 mC/Kg.y (98 mR/year), while indoors the average exposure rates were in some cases three times higher than the equivalent average obtained outdoors. Some of potential causes to the fact that exposure to gamma radiation is, in general, higher indoors than outdoors are examined and discussed. (author) [pt

E-mail: marquesapl@ufrrj.br We studied levels and nutrient availability in the soil and grazing of cattle in Middle Paraíba, RJ, Brazil in the early dry season (May-June and rainy (November-December in seven cattle herds with a history of clinical deficiencies of Na, Cu, Co and P, identified through visits to farmers. The mineral contents in the samples were determined by atomic absorption spectrophotometry and values obtained were compared with clinical signs found. Low values of P and Na were confirmed and although the lack of Ca and Mg is uncommon, some samples showed low rates. We found high values of Fe with possible interference in the absorption of Cu, the main clinical deficiency identified in the region, and high values of Al, Zn and Mn. The results indicate that most mineral deficiencies diagnosed in those herds is due to antagonistic effects of minerals that are not deficient.

    The hydrogeology and water quality of the Snake River alluvial aquifer at the Jackson Hole Airport in northwest Wyoming was studied by the U.S. Geological Survey, in cooperation with the Jackson Hole Airport Board, during water years 2011 and 2012 as part of a followup to a previous baseline study during September 2008 through June 2009. Hydrogeologic conditions were characterized using data collected from 19 Jackson Hole Airport wells. Groundwater levels are summarized in this report and the direction of groundwater flow, hydraulic gradients, and estimated groundwater velocity rates in the Snake River alluvial aquifer underlying the study area are presented. Analytical results of groundwater samples collected from 10 wells during water years 2011 and 2012 are presented and summarized. The water table at Jackson Hole Airport was lowest in early spring and reached its peak in July or August, with an increase of 12.5 to 15.5 feet between April and July 2011. Groundwater flow was predominantly horizontal but generally had the hydraulic potential for downward flow. Groundwater flow within the Snake River alluvial aquifer at the airport was from the northeast to the west-southwest, with horizontal velocities estimated to be about 25 to 68 feet per day. This range of velocities slightly is broader than the range determined in the previous study and likely is due to variability in the local climate. The travel time from the farthest upgradient well to the farthest downgradient well was approximately 52 to 142 days. This estimate only describes the average movement of groundwater, and some solutes may move at a different rate than groundwater through the aquifer. The quality of the water in the alluvial aquifer generally was considered good. Water from the alluvial aquifer was fresh, hard to very hard, and dominated by calcium carbonate. No constituents were detected at concentrations exceeding U.S. Environmental Protection Agency maximum contaminant levels or health

    Full Text Available SUMMARY. - Seismic activity associated with the collision of the continental
    part of the Australian plate with the oceanic Melanesian arcs along Papua New
    Guinea and the Banda arc provides an unusual opportunity to study the relative
    excitation of the seismic shear waves Sn and Lg. These waves are produced by
    earthquakes located along the arcs in the upper 200 km of the earth and are
    recorded by the Australian WWSSN Stations at Charters Towers (CTA and Alice
    Springs (ASP. The paths to these stations are predominantly continental. The data
    clearly show that for events located at crustal depths, Lg is the predominant phase
    on the records and Sn is either absent or very weak. For events deeper than about
    50-70 km, Sn becomes the predominant phase on the records. These observations
    arc in qualitative agreement with the explanations of Sn and Lg as higher
    modes of surface waves, for the particle displacement amplitudes are maximum
    within the crust for Lg and maximum within the lid of the lithospheric mantle
    for Sn. The data suggest that either the crustal wave guide for Lg is more
    efficient than that for Sn, or that Lg is more easily excited than Sn. No clear
    Lg is observed from shallow earthquakes when the length of the segment of the
    path crossing oceanic structure is greater than about 200 km. Also, widespread
    Quaternary volcanism within the « stable » area of central Papua New Guinea
    to the south of the mobile belt does not seem to affect the efficient transmission
    of high-frequency (1 Hz shear energy.
    The paths from events located along the New Hebrides, Solomon, and New
    Britain arcs to Australia traverse oceanic structure, and no Lg is observed from
    these paths. The inefficient propagation of Sn along these paths from both
    shallow and intermediate-depth events can be explained as follows: 1 For

    Full Text Available The limits of life of aerobic microorganisms are well understood, but the responses of anaerobic microorganisms to individual and combined extreme stressors are less well known. Motivated by an interest in understanding the survivability of anaerobic microorganisms under Martian conditions, we investigated the responses of a new isolate, Yersinia intermedia MASE-LG-1 to individual and combined stresses associated with the Martian surface. This organism belongs to an adaptable and persistent genus of anaerobic microorganisms found in many environments worldwide. The effects of desiccation, low pressure, ionizing radiation, varying temperature, osmotic pressure, and oxidizing chemical compounds were investigated. The strain showed a high tolerance to desiccation, with a decline of survivability by four orders of magnitude during a storage time of 85 days. Exposure to X-rays resulted in dose-dependent inactivation for exposure up to 600 Gy while applied doses above 750 Gy led to complete inactivation. The effects of the combination of desiccation and irradiation were additive and the survivability was influenced by the order in which they were imposed. Ionizing irradiation and subsequent desiccation was more deleterious than vice versa. By contrast, the presence of perchlorates was not found to significantly affect the survival of the Yersinia strain after ionizing radiation. These data show that the organism has the capacity to survive and grow in physical and chemical stresses, imposed individually or in combination that are associated with Martian environment. Eventually it lost its viability showing that many of the most adaptable anaerobic organisms on Earth would be killed on Mars today.

    Full Text Available The aim of this project was to evaluate the Regenerative and Analogous Agroforestry Systems (SAFRA on environmental sustainability, using as indicators the biomass increase or accumulation and nutrients deposition through litter arboreal species. This work is part of PRODETAB/EMBRAPA - 39th Project – and was developed in Goura Vrindávna Farm, Paraty - RJ. 28 multipurpose arboreal species were cultivated in three agroforestry treatments, Minimum SAFRA (simplified system of the banana culture enrichment, Absolute SAFRA (dense and diversified system and Modified SAFRA (the same composition of the latter SAFRA plus soil fertilization. For evaluating nutrients deposition through litter fifteen months after planting, samples of three Safra and two control treatments, banana culture and area in fallow, were collected with 625cm2 collectors. Macro and micronutrients determinations were done in the samples. The Minimum SAFRA was the system that deposited the greatest weight in litter (32.4 t.ha-1 and the greatest content of micro and macronutrients. Excepting C and H, N was the one which presented greatest content in the five treatments, and Fe was the micronutrients of major deposition. The vegetation pruning in the SAFRA benefited the nutrients cycling and contributed to its content elevation in litter. Considering the nutrients deposition through litter, the SAFRAs were the most promissory systems in the re-establishing of these ecological functions, when compared to area in fallow and banana monoculture.

    Full Text Available Diazepam suppositories are widely used by children and elderly, and require close attention to quality control because it is a controlled prescription drug. The objective of the study was to analyze diazepam suppositories manipulated in Campos dos Goytacazes, RJ, to verify if they are within the required quality standards, and offer safety and efficiency to patients. We analyzed samples of 5mg diazepam suppositories acquired in five randomly selected pharmacies, identified as Pharmacy A, Pharmacy B, Pharmacy C, Pharmacy D, and Pharmacy E. We ran tests on average weight, organoleptic control, hardness, melting point, and dissolution. Data was analyzed and compared with the requirements of the Brazilian Pharmacopoeia. This analysis was made over a table in Excel. We conclude that only C Pharmacy was approved in all tests, and this is the only laboratory that has analyzed the quality of the product warranty. Laboratories A, B, D and E have been approved in some tests, and failed one or more tests. To ensure quality control, suppositories needed to pass in all tests, which was not the case of these labs. Therefore, we recommended the following procedures to the investigated laboratories: changes in packaging, greater precision in handling, quality control prior to dispensing the product, and efficient pharmaceutical care service.

    L.G. Ramensky (1884-1953) was an outstanding Soviet geobotanist of the first part of XX century. Considered is his theoretical legacy and its contribution to modern vegetation science. L.G. Ramensky formulated the principle of vegetation continuum based on which the modern paradigm of vegetation science has been put into shape. The scientist made a contribution to the development of such important theoretical conceptions as types of plant strategy, coenosis and coenobiosis (coexistence of species), patterns of interannual variability in plant communities, ecological successions. The unique ecological scales were established by L.G. Ramensky that characterize the distribution of 1400 species over the gradients of soil moistening, richness, and salinization as well as moistening variability, pastoral digression, and alluvial intensity. He came out against mechanistic notions by V.N. Sukachev on a biogeocoenosis structure. The scientist did not offer his own method of plant communities classification but his well-reasoned criticism of dominant classification played a great role in adoption of floristical classification principles (Braun-Blanquet approach) by phytocenology in our country.

    A stoichiometric displacement model for retention (SDM-R) of small solutes and proteins based on hydrophilic interaction chromatography (HILIC) was presented. A linear equation that related the logarithm of the capacity factor of the solute to the logarithm of the concentration of water in the mobile phase was derived. The stoichiometric displacement parameters, Z (the number of water molecules required to displace a solute from ligands) and lgI (containing a number of constants that relate to the affinity of solute to the ligands) could be obtained from the slope and the intercept of the linear plots of lgk' vs. lg[H 2 O]. The retention behaviors and retention mechanism of 15 kinds of small solutes and 6 kinds of proteins on 5 kinds HILIC columns with different ligands were investigated with SDM-R in typical range of water concentration in mobile phase. A good linear relationship between lgk' and lg[H 2 O] demonstrated that the most rational retention mechanism of solute in HILIC was a stoichiometric displacement process between solute and solvent molecules with water as displacing agents, which was not only valid for small solutes, but also could be used to explain the retention mechanism of biopolymers in HILIC. Comparing with the partition and adsorption models in HILIC, SDM-R was superior to them. Copyright © 2017 Elsevier B.V. All rights reserved.

    The purpose of this study was to compare manual maneuvering with the use of a Jackson table when moving patients with cervical spine instability from the supine to the surgically appropriate prone position. The range of motion (ROM) of the cervical spine of a fresh cadaver was measured. A ligamentous instability was created at the C5-6 level, and the increased ROM was confirmed. Sensors for an electromagnetic motion analysis device were fixed to the anterior portions of the C-5 and C-6 vertebral bodies (VBs) using machined polyethylene mounts and carbon fiber rods that were inserted into the VBs. The sensors were used to measure cervical flexion, lateral bending, and axial rotation during the two transfer procedures. The cadaver was then moved from the supine position on a hospital bed to the prone position for surgery. The manual technique was performed by four trained individuals who moved the cadaver from the hospital bed while rotating it 180 degrees axially onto the surgical table. In using the Jackson table, the cadaver was moved from the bed to the table in the supine position and then the Jackson table rotated the cadaver to the prone position. The two techniques were tested with and without the use of a collar and were repeated five times. Analysis of the data indicated that when moving a patient into the prone surgical position, the use of a cervical collar and the Jackson table significantly reduced the cervical motion in all angular planes compared with that of manual transfer. The use of a cervical collar and the Jackson table may reduce the possibility of further spinal cord compromise. Because manual transfers are performed routinely, this warrants further study.

  3. Do happy faces really modulate liking for Jackson Pollock art and statistical fractal noise images?

    Full Text Available Flexas et al. (2013 demonstrated that happy faces increase preference for abstract art if seen in short succession. We could not replicate their findings. In our first experiment, we tested whether valence, saliency or arousal of facial primes can modulate liking of Jackson Pollock art crops. In the second experiment, the emphasis was on testing another type of abstract visual stimuli which possess similar low-level image features: statistical fractal noise images. Pollock crops were rated significantly higher when primed with happy faces in contrast to neutral faces, but not differently to the no-prime condition. Findings of our study suggest that affective priming with happy faces may be stimulus-specific and may have inadvertent effects on other abstract visual material.

    The present work aimed the study of the dispersion profiles of radionuclides released in liquid radioactive effluents from the Central Nuclear Almirante Alvaro Alberto (CNAAA), in the Ilha Grande Bay, located in Angra dos Reis, RJ. Taking the overall activity released by liquid effluents discharge from the CNAAA in the Piraquara de Fora Bay as a reference parameter to the dilution rates scanning, the accordance level between the achieved 3 H results (1 :16) and those reported by Franklin (1 :20) can be seen as relevant. The post-1965 137 Cs concentration raise can be regarded as a consequence of the operational start up in the CNAAA, being the Ribeira Bay considered its preferential uptake, from the plume displacement high tide, as well as its retention, due to local deposition favourable trends. The evaluation of the prevailing mechanism on long half-life radio isotopes dispersion pointed out its dependence on meteorological condition parameters, during the sampling procedures. If diffusion prevailingness occurs, both 223 Ra and 224 Ra distribution pathways result in diffusion coefficients ranging from 20,12 ± 3,81 - 21,07 ± 3,91 km 2 .d -1 to a 228 Ra offshore flux and time of residence of, respectively, 3,18 ± 1,01 x 108 Bq.d-1 and 25,35 ± 0,45 days. On the other hand, an uppermost advection process provided 228 Ra offshore flux and time of residence of, respectively, 2,26 ± 0,424 x 10 8 Bq.d -1 and 13,08 ± 0,21 days. (author)

    Full Text Available RESUMO Este trabalho apresenta um modelo para determinar a fragilidade ambiental em bacias hidrográficas. O estudo foi realizado na Bacia do Rio Aldeia Velha, RJ, localizada na zona de contato e transição entre a baixada litorânea e o relevo montanhoso da Serra do Mar. Fatores que influenciam a ocorrência de processos erosivos foram integrados por algoritmos em um SIG para construção de classes de fragilidade. A análise multicriterial considerou o modelo numérico de terreno, dados oficiais sobre variáveis ambientais, imagem orbital de alta resolução e a opinião de especialistas. Através de informações secundárias sobre pedologia, intensidade das chuvas e declividade do terreno gerou-se o Mapa de Fragilidade Potencial (MFP. Através da combinação desse mapa com informações sobre uso e cobertura da terra obteve-se o Mapa da Fragilidade Emergente (MFE. Os resultados mostram que mais de 70% da área da bacia possui fragilidade ambiental considerada alta ou muito alta, tanto potencial como emergente. Os Processos Erosivos Aparentes (PEA relacionaram-se positivamente com as áreas de alta fragilidade nos produtos cartográficos finais, destacando regiões mais propensas à intensificação de movimentos de massa e prioritárias para prevenção contra perda de solo. Os modelos geraram informações importantes para o planejamento territorial, possibilitando um zoneamento acessível e de fácil atualização para as prefeituras municipais e organizações da sociedade civil, inclusive para o monitoramento das áreas de alta fragilidade ambiental.

    Full Text Available O objetivo deste trabalho foi caracterizar o comportamento hidrológico, o volume de entrada e saída de água da bacia hidrográfica do rio Debossan, onde se localiza uma importante estação de captação de água, administrada pela Concessionária de Águas e Esgotos de Nova Friburgo LTDA. (CAENF, inserida na Reserva Ecológica de Macaé de Cima, Município de Nova Friburgo, Rio de Janeiro. Para isso, foram obtidos dados de vazão e precipitação diários do período de janeiro de 2002 a dezembro de 2004. A partir desses dados, foram calculados alguns parâmetros hidrológicos, como vazão específica e deflúvio. A precipitação média observada nos três anos foi de 2.163 mm, sendo que os meses de dezembro/2002 e janeiro/2003 apresentaram os máximos valores. A vazão média anual no período foi de 0,86 m³/s, apresentando o mês de dezembro de 2002 com maior índice e setembro de 2004 com o menor. O balanço hídrico, em termos médios anuais nos três anos de medições, apresentou uma evapotranspiração de 1.923,04 mm, equivalendo a 88% da precipitação convencional. Pode-se dizer que o ecossistema florestal exerce efeito tamponante sobre a quantidade de água da bacia hidrográfica, mantendo uma grande vazão nos meses de menor pluviosidade. Ao analisar a relação entre a entrada de água na bacia, o uso atual do solo e a quantidade de água produzida, concluiu-se que uma bacia hidrográfica bem preservada tem fundamental importância na manutenção constante da vazão ao longo do ano, além da visível participação na qualidade da água.The objective of this work was to characterize the hydrological behavior and the volume of water entering and leaving the Debossan river watershed, where an important water captation plant is situated, managed by the Nova Friburgo Water and Sewage Treatment Company LTDA (CAENF, within the 'Macaé de Cima' Ecological Reserve, Nova Friburgo-RJ.

    This article describes the use of survey research in collaboration with the African American urban community of Georgetown, Jackson, Mississippi to identify and understand prostate cancer knowledge, resource utilization, and health education strategies considered most effective in reaching the community with prostate cancer prevention messages. The study revealed profound needs in disease identification and resources awareness and utilization. Barriers to utilization were identified by participants to include lack of self-efficacy, low self-esteem, lack of trust in the health care system, limited knowledge of prostate pathology, and limited ability to pay. Participants' recommended strategies for reaching the community with prostate cancer education include traditional and nontraditional strategies. The list of recommendations exclude modern-day outlets such as handheld devices, Twitter, Facebook, blogs, wikis, and other Internet-based outlets. The findings provide a road map for program development and an intervention research agenda custom-tailored to the Georgetown community of Jackson, Mississippi.

    Full Text Available Patterns of fat distribution are heavily influenced by psychological stress, sex, and among women, by menopause status. Emerging evidence suggests the lack of perceived neighborhood safety due to crime may contribute to psychological stress and obesity among exposed residents. Our objective is to determine if perceived neighborhood safety is associated with abdominal adiposity among African-American men and women, and among pre- and postmenopausal women in the Jackson Heart Study.We examined associations between perceived neighborhood safety, fat distribution, and other individual-level covariates among Jackson Heart Study participants (N = 2,881. Abdominal adiposity was measured via computed tomography scans measuring the volumes of visceral, subcutaneous and total adipose tissue. We also measured body mass index (BMI, and waist circumference. Multivariable regression models estimated associations between perceived neighborhood safety, adiposity, and covariates by sex and menopause status.Adjusting for all covariates, women who strongly disagreed their neighborhood was safe from crime had a higher BMI compared to women who felt safe [Std B 0.083 95% CI (0.010, 0.156]. Premenopausal women who felt most unsafe had higher BMI, waist circumference, and volumes of visceral and total adipose tissue than those who felt safe [Std B 0.160 (0.021, 0.299, Std B 0.142 (0.003, 0.280, Std B 0.150 (0.014, 0.285, Std B 0.154 (0.019, 0.290, respectively]. We did not identify associations between neighborhood safety and adiposity among men and postmenopausal women.Our data suggest that abdominal adipose tissue distribution patterns are associated with perceived neighborhood safety in some groups, and that patterns may differ by sex and menopause status, with most associations observed among pre-menopausal women. Further research is needed to elucidate whether there are causal mechanisms underlying sex and menopause-status differences that may mediate

    A detailed inventory of irrigated crop acreage is not available at the level of resolution needed to accurately estimate water use or to project future water demands in many Florida counties. This report provides a detailed digital map and summary of irrigated areas for 2014 within Jackson, Calhoun, and Gadsden Counties in Florida, and Houston County in Alabama. The irrigated areas were delineated using land-use data and orthoimagery that were then field verified between June and November 2014. Selected attribute data were collected for the irrigated areas, including crop type, primary water source, and type of irrigation system. Results of the 2014 study indicate that an estimated 31,608 acres were irrigated in Jackson County during 2014. This estimate includes 25,733 acres of field crops, 1,534 acres of ornamentals and grasses (including pasture), and 420 acres of orchards. Specific irrigated crops include cotton (11,759 acres), peanuts (9,909 acres), field corn (2,444 acres), and 3,235 acres of various vegetable (row) crops. The vegetable acreage includes 1,714 acres of which 857 acres were planted with both a spring and fall crop on the same field (double cropped). Overall, groundwater was used to irrigate 98.6 percent of the total irrigated acreage in Jackson County during 2014, whereas surface water and wastewater were used to irrigate the remaining 1.4 percent.

    Many adults with elevated clinic blood pressure (BP) have lower BP when measured outside the clinic. This phenomenon, the "white-coat effect," may be larger among older adults, a population more susceptible to the adverse effects of low BP. The authors analyzed data from 257 participants in the Jackson Heart Study with elevated clinic BP (systolic/diastolic BP [SBP/DBP] ≥140/90 mm Hg) who underwent ambulatory BP monitoring (ABPM). The white-coat effect for SBP was larger for participants 60 years and older vs those younger than 60 years in the overall population (12.2 mm Hg, 95% confidence interval [CI], 9.2-15.1 mm Hg and 8.4 mm Hg, 95% CI, 5.7-11.1, respectively; P=.06) and among those without diabetes or chronic kidney disease (15.2 mm Hg, 95% CI, 10.1-20.2 and 8.6 mm Hg, 95% CI, 5.0-12.3, respectively; P=.04). After multivariable adjustment, clinic SBP ≥150 mm Hg vs coat effect. Studies are needed to investigate the role of ABPM in guiding the initiation and titration of antihypertensive treatment, especially among older adults. ©2015 Wiley Periodicals, Inc.

    This study examined the perceived psychosocial functions of flashbulb memories: It compared positive and negative public flashbulb memories (positive: Bin Laden's death, negative: Michael Jackson's death) with private ones (positive: pregnancy, negative: death of a loved one). A sample of n = 389 young and n = 176 middle-aged adults answered canonical category questions used to identify flashbulb memories and rated the personal significance, the psychological temporal distance, and the functions of each memory (i.e., self-continuity, social-boding, directive functions). Hierarchical regressions showed that, in general, private memories were rated more functional than public memories. Positive and negative private memories were comparable in self-continuity and directionality, but the positive private memory more strongly served social functions. In line with the positivity bias in autobiographical memory, positive flashbulb memories felt psychologically closer than negative ones. Finally, middle-aged adults rated their memories as less functional regarding self-continuity and social-bonding than young adults. Results are discussed regarding the tripartite model of autobiographical memory functions.

    To test the effectiveness of a point-of-decision intervention to prompt walking, versus motorized transport, in a large metropolitan airport. We installed point-of-decision prompt signage at 4 locations in the airport transportation mall at Hartsfield-Jackson Atlanta International Airport (Atlanta, GA) at the connecting corridor between airport concourses. Six ceiling-mounted infrared sensors counted travelers entering and exiting the study location. We collected traveler counts from June 2013 to May 2016 when construction was present and absent (preintervention period: June 2013-September 2014; postintervention period: September 2014-May 2016). We used a model that incorporated weekly walking variation to estimate the intervention effect on walking. There was an 11.0% to 16.7% relative increase in walking in the absence of airport construction where 580 to 810 more travelers per day chose to walk. Through May 2016, travelers completed 390 000 additional walking trips. The Walk to Fly study demonstrated a significant and sustained increase in the number of airport travelers choosing to walk. Providing signage about options to walk in busy locations where reasonable walking options are available may improve population levels of physical activity and therefore improve public health.

    Using Jackson Heart Study data, we examined associations of multiple measures of perceived discrimination with health behaviours among African-Americans (AA). The cross-sectional associations of everyday, lifetime and burden of discrimination with odds of smoking and mean differences in physical activity, dietary fat and sleep were examined among 4925 participants aged 35-84 years after adjustment for age and socioeconomic status (SES). Men reported slightly higher levels of everyday and lifetime discrimination than women and similar levels of burden of discrimination as women. After adjustment for age and SES, everyday discrimination was associated with more smoking and a greater percentage of dietary fat in men and women (OR for smoking: 1.13, 95% CI 1.00 to 1.28 and 1.19, 95% CI 1.05 to 1.34; mean difference in dietary fat: 0.37, pwomen, respectively). Everyday and lifetime discrimination were associated with fewer hours of sleep in men and women (mean difference for everyday discrimination: -0.08, pdiscrimination: -0.08, pdiscrimination was associated with more smoking and fewer hours of sleep in women only. Higher levels of perceived discrimination were associated with select health behaviours among men and women. Health behaviours offer a potential mechanism through which perceived discrimination affects health in AA. Published by the BMJ Publishing Group Limited.

    Cerebral lateralization is an evolutionarily deep-rooted trait, ubiquitous among the vertebrates and present even in some invertebrates. Despite the advantages of cerebral lateralization in enhancing cognition and facilitating greater social cohesion, large within population laterality variation exists in many animal species. It is proposed that this variation is maintained due links with inter-individual personality trait differences. Here we explored for lateralization in Port Jackson sharks (Heterodontus portusjacksoni) using T-maze turn and rotational swimming tasks. Additionally, we explored for a link between personality traits, boldness and stress reactivity, and cerebral lateralization. Sharks demonstrated large individual and sex biased laterality variation, with females demonstrating greater lateralization than males overall. Stress reactivity, but not boldness, was found to significantly correlate with lateralization strength. Stronger lateralized individuals were more reactive to stress. Demonstrating laterality in elasmobranchs for the first time indicates ancient evolutionary roots of vertebrate lateralization approximately 240 million years old. Greater lateralization in female elasmobranchs may be related enhancing females' ability to process multiple stimuli during mating, which could increase survivability and facilitate insemination. Despite contrasting evidence in teleost fishes, the results of this study suggest that stress reactivity, and other personality traits, may be linked to variation in lateralization.

    Iatrogenic biliary injury is the most significant complication after laparoscopic cholecystectomy. We present our experience with an alternative diagnostic approach using transcatheter cholangiography (TCC) through a Jackson-Pratt (JP) drain and discuss potential benefits and limitations of the technique. From March 2002 to February 2012, 40 patients with major postoperative biliary injury underwent biliary reconstruction at our institution. Mean age was 51.7 ± 18.1 years (range, 19 to 86 years) with 30 (75%) females. Seventeen (42.5%) injuries were detected intraoperatively and in 13 (32.5%) cases, JP drains were placed for biliary drainage. Lesions were classified according to Bismuth grade: I (10 patients [25%]), II (10 patients [25%]), III (six patients [15%]), IV (10 patients [25%]), and V (four patients [10%]). TCC was performed in seven patients with JP drains (53.8%). It fully defined the injury site in three cases of limited magnetic resonance cholangiopancreatography (MRCP) such as common hepatic duct and common bile duct leaks and in four cases (57.1%) that endoscopic retrograde cholangiopancreatography (ERCP) was limited as a result of clipping of the distal common bile duct. TCC showed promising results in cases of limited MRCP and ERCP such as fistulous orifices or leakage. It may represent an alternative adjunct in the diagnostic armamentarium of complex biliary injuries.

    Full Text Available Climate change is warming the world’s oceans at an unprecedented rate. Under predicted end-of-century temperatures, many teleosts show impaired development and altered critical behaviors, including behavioral lateralisation. Since laterality is an expression of brain functional asymmetries, changes in the strength and direction of lateralisation suggest that rapid climate warming might impact brain development and function. However, despite the implications for cognitive functions, the potential effects of elevated temperature in lateralisation of elasmobranch fishes are unknown. We incubated and reared Port Jackson sharks at current and projected end-of-century temperatures and measured preferential detour responses to left or right. Sharks incubated at elevated temperature showed stronger absolute laterality and were significantly biased towards the right relative to sharks reared at current temperature. We propose that animals reared under elevated temperatures might have more strongly lateralized brains to cope with deleterious effects of climate change on brain development and growth. However, far more research in elasmobranch lateralisation is needed before the significance of these results can be fully comprehended. This study provides further evidence that elasmobranchs are susceptible to the effects of future ocean warming, though behavioral mechanisms might allow animals to compensate for some of the challenges imposed by climate change.

    There has been a long-standing link between the civil and criminal commitment procedures for individuals found incompetent to stand trial (IST). In the criminal system, when restoration of competency fails to be realized in a reasonable time, the civil commitment process becomes the default system for commitment. While there have been recent calls for improved mechanisms for predicting competence restorability, there has been little attention paid to individuals who can oscillate indefinitely between commitment in both the criminal and civil systems. We provide an example of one such case where an individual falls into the legal space that sits outside of the judicial guidance outlined in the landmark case Jackson v. Indiana. This review of Oregon public documents surrounding an ongoing murder case highlights the potential for indefinite detention of individuals who have been charged with serious crimes that do not have a statute of limitations, who are unlikely to be restored to competency to stand trial, and who are inconsistently found to be dangerous under civil commitment standards.

    A retained postoperative drain tube, trapped by one or more of the sutures of the abdominal wall closure, is a rare complication of frustrating consequences and potential legal repercussions. There are few reports of techniques for minimally invasive removal of an anchored postoperative drain tube, which not infrequently has been treated by reopening the wound. A 75 years-old man with a left T2-T3N0M0 renal carcinoma was treated with transperitoneal laparoscopic nephrectomy and a Jackson-Pratt drain was left in place. Drain removal the day after revealed impossible, as if being caught with fascial suture. With the patient under sedation, we introduced a Sachse urethrotome parallel to the drain, and the abdominal fascia was identified, then the polyglycolic stitch anchoring it to the wall could be severed, freeing the drain. Percutaneous extraction with the Sachse urethrotome of an anchored postoperative drain, should be the first option, before trying a forced traction or using more complex options. This technique is for the first time published in the Spanish bibliography, and we think this possibility should be disclosed to abdominal surgeons.

    Full Text Available O trabalho discute temas relacionados à distribuição de sedimentos costeiros, parâmetros granulométricos e modelos bidimensionais de transporte de sedimentos. Parte-se da hipótese de que a disposição dos materiais na superfície de fundo das enseadas permite o diagnóstico de processos associados à hidrodinâmica marinha e sua participação no controle do transporte e distribuição dos sedimentos costeiros. O objetivo central é então caracterizar a textura superficial do depósito costeiro e apresentar correlações entre os parâmetros estatísticos que permitam o diagnóstico de processos relacionados à distribuição e ao transporte dos sedimentos no sistema praia-antepraia. Como área de pesquisa, foram selecionadas três enseadas no município de Arraial do Cabo (RJ. As etapas metodológicas partiram da definição de uma malha amostral, coleta de 96 amostras de sedimentos em profundidades entre 1 e 23 metros, seguido por análises granulométricas em laboratório, determinação de parâmetros estatísticos e cálculo do modelo de tendências de transporte de sedimentos (GSTA. Os resultados apontam a ocorrência majoritária de areias finas (41,6% e médias (17,7% moderadamente bem selecionadas como o principal depósito nas enseadas, no entanto, além dos depósitos palimpsestos, núcleos de deposição de areias grossas (14,6% e muito grossas (8,3% e, por outro lado, areias muito finas (5,2% e siltes (6,2% também foram identificados e discutidos à luz de sua significância ambiental. Quanto ao modelo de transporte, o melhor ajuste (65% foi feito com o padrão FB, que indica sedimentos mais finos e mais bem selecionados na direção do transporte. Conclui-se que os depósitos palimpsestos são responsáveis pelo abastecimento da praia emersa e que os esforços de interpretação dos parâmetros estatísticos e a geração de resultados de transporte de sedimentos a partir de modelos não hidrodinâmicos geram informa

    This work was conducted in the city of Campos dos Goytacazes/RJ, in which four residual soils collected in the region were technologically characterized. We sought to determine their properties, such as analysis of the colors after firing, aiming at its use in ceramic art. To this end the tests were conducted in the laboratories of the Universidade Estadual do Norte Fluminense Darcy Ribeiro (UENF) and that are granulometry (by sieving and sedimentation), specific mass of grains, chemical analysis by X-ray fluorescence, diffraction mineralogical identification X-ray, differential thermal analysis and thermogravimetry. The soils were analyzed before drying at 110 deg C and after burning the different temperatures (500 deg C 750 deg C and 950 deg C). The analyzed results showed the physical composition, chemical and mineralogical of raw material. After burning was possible to observe several color variations. (author)

    Background The calibration to Isotope Dilution Mass Spectroscopy (IDMS) traceable creatinine is essential for valid use of the new Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation to estimate the glomerular filtration rate (GFR). Methods For 5,210 participants in the Jackson Heart Study (JHS), serum creatinine was measured with a multipoint enzymatic spectrophotometric assay at the baseline visit (2000–2004) and re-measured using the Roche enzymatic method, traceable to IDMS in a subset of 206 subjects. The 200 eligible samples (6 were excluded, 1 for failure of the re-measurement and 5 for outliers) were divided into three disjoint sets - training, validation, and test - to select a calibration model, estimate true errors, and assess performance of the final calibration equation. The calibration equation was applied to serum creatinine measurements of 5,210 participants to estimate GFR and the prevalence of CKD. Results The selected Deming regression model provided a slope of 0.968 (95% Confidence Interval (CI), 0.904 to 1.053) and intercept of −0.0248 (95% CI, −0.0862 to 0.0366) with R squared 0.9527. Calibrated serum creatinine showed high agreement with actual measurements when applying to the unused test set (concordance correlation coefficient 0.934, 95% CI, 0.894 to 0.960). The baseline prevalence of CKD in the JHS (2000–2004) was 6.30% using calibrated values, compared with 8.29% using non-calibrated serum creatinine with the CKD-EPI equation (P creatinine measurements in the JHS and the calibrated values provide a lower CKD prevalence estimate.

    Full Text Available Even though some medications have the potential to slow the progress of atherosclerosis and development of CVD, there are many at-risk individuals who continue to resist the benefits that are available by not following the advice of medical professionals. Non-adherence to prescribed drug regimens is a pervasive medical problem that negatively affects treatment outcomes. Information from standardized interviews of 5301 African Americans participating in the Jackson Heart Study was examined to determine the association between demographic parameters, behavior including adherence to prescribed medical regimens, and health outcomes. Data were also collected at Annual Follow-Up and Surveillance visits. During the two weeks prior to the examination visit, almost 52% of the participants reported taking blood pressure medication, 14% took cholesterol medication, 16% took medication for diabetes, and 19% took blood thinning medication. Of those who did not take the prescribed medications, the reasons given were the following: 47% were in a hurry, too busy, or forgot to take medications; 23% were trying to do without medications; 18% had no money to purchase medications; 19% indicated that the medications made them feel bad; 17% felt that they could not carry out daily functions when taking medications. The African American population can benefit from heightened awareness of the risk factors that are associated with CVD and the benefits of following a prescribed treatment regimen. Unacceptable secondary effects of prescribed medication comprised an important cause of non-compliance. Encouragement of this population to communicate with their healthcare providers to ensure that medication regimens are better tolerated could increase compliance and improve health outcomes.

    Full Text Available Abstract Background This study investigated the number of pedometer assessment occasions required to establish habitual physical activity in African American adults. Methods African American adults (mean age 59.9 ± 0.60 years; 59 % female enrolled in the Diet and Physical Activity Substudy of the Jackson Heart Study wore Yamax pedometers during 3-day monitoring periods, assessed on two to three distinct occasions, each separated by approximately one month. The stability of pedometer measured PA was described as differences in mean steps/day across time, as intraclass correlation coefficients (ICC by sex, age, and body mass index (BMI category, and as percent of participants changing steps/day quartiles across time. Results Valid data were obtained for 270 participants on either two or three different assessment occasions. Mean steps/day were not significantly different across assessment occasions (p values > 0.456. The overall ICCs for steps/day assessed on either two or three occasions were 0.57 and 0.76, respectively. In addition, 85 % (two assessment occasions and 76 % (three assessment occasions of all participants remained in the same steps/day quartile or changed one quartile over time. Conclusion The current study shows that an overall mean steps/day estimate based on a 3-day monitoring period did not differ significantly over 4 – 6 months. The findings were robust to differences in sex, age, and BMI categories. A single 3-day monitoring period is sufficient to capture habitual physical activity in African American adults.

    Chronic kidney disease (CKD) remains a prevalent public health problem that disproportionately affects African Americans, despite intense efforts targeting traditional risk factors. Periodontal disease, a chronic bacterial infection of the oral cavity, is both common and modifiable and has been implicated as a novel potential CKD risk factor. The authors seek to examine to what extent periodontal disease is associated with kidney function decline. This retrospective cohort study examines 699 African American participants with preserved kidney function (defined by estimated glomerular filtration rate (eGFR) >60 mL/minute/1.73 m(2) at baseline) who underwent complete dental examinations as part of the Dental-Atherosclerosis Risk in Communities study (1996 to 1998) and subsequently enrolled in the Jackson Heart Study (2000 to 2004). Using multivariable Poisson regression, the authors examined the association of periodontal disease (severe versus non-severe) with incident CKD, defined as incident eGFR periodontal disease. There were 21 cases (3.0%) of incident CKD after a mean follow-up of 4.8 (± 0.6) years. Compared with participants with non-severe periodontal disease, those with severe periodontal disease had a four-fold greater rate of incident CKD (adjusted incidence rate ratio 4.18 [95% confidence interval 1.68 to 10.39], P = 0.002). Severe periodontal disease is prevalent among a population at high risk for CKD and is associated with clinically significant kidney function decline. Further research is needed to determine if periodontal disease treatment alters the trajectory of renal deterioration.

    An investigation of the ground-water resources near Jackson, West Tennessee, was conducted during 1988-89. The study included determination of the occurrence of contaminants in the shallow aquifer using soil-gas analyses in the unsaturated zone. Between 1980 and 1988, an underground fuel-storage tank leaked about 3,000 gallons of unleaded fuel to the water table about 4 feet below land surface. A survey of soil gas using a gas chromatograph equipped with a photoionization detector showed concentrations of volatile organic compounds greater than IO, 000 parts per million near the leak These compounds were detected in an area about 240 feet long and 110 feet wide extending west from the point source. The chromatograms provided two distinct 'fingerprints' of volatile organic compounds. The first revealed the presence of benzene, toluene, andxylenes, which are constituents of unleaded fuel, in addition to other volatile compounds, in soil gas in the area near the leak The second did not reveal any detectable benzene, toluene, or xylenes in the soil-gas samples, but showed the presence of other unidentified volatile organic compounds in soil gas north of the storage tank. The distribution of total concentrations of volatile organic compounds in the unsaturated zone indicated that a second plume about 200 feet long and 90 feet wide was present about 100 feet north of the storage tank The second plume could have been the result of previous activities at this site during the 1950's or earlier. Activities at the site are believed to have included storage of solvents used at the nearby railyard and flushing of tanks containing tar onto a gravel-covered parking area. The delineation of these plumes has shown that soil-gas analyses can be a useful technique for identifying areas of contamination with volatile organic compounds in shallow water-table aquifers and may have broad applications in similar situations where the water table is relatively close to the surface.

    Cigarette smoking has been linked with several factors associated with cardiac dysfunction. We hypothesized that cigarette smoking is associated with left ventricular (LV) structure and function, and incident heart failure (HF) hospitalization. We investigated 4129 (never smoker n=2884, current smoker n=503, and former smoker n=742) black participants (mean age, 54 years; 63% women) without a history of HF or coronary heart disease at baseline in the Jackson Heart Study. We examined the relationships between cigarette smoking and LV structure and function by using cardiac magnetic resonance imaging among 1092 participants, cigarette smoking and brain natriuretic peptide levels among 3325 participants, and incident HF hospitalization among 3633 participants with complete data. After adjustment for confounding factors, current smoking was associated with higher mean LV mass index and lower mean LV circumferential strain ( P <0.05, for both) in comparison with never smoking. Smoking status, intensity, and burden were associated with higher mean brain natriuretic peptide levels (all P <0.05). Over 8.0 years (7.7-8.0) median follow-up, there were 147 incident HF hospitalizations. After adjustment for traditional risk factors and incident coronary heart disease, current smoking (hazard ratio, 2.82; 95% confidence interval, 1.71-4.64), smoking intensity among current smokers (≥20 cigarettes/d: hazard ratio, 3.48; 95% confidence interval, 1.65-7.32), and smoking burden among ever smokers (≥15 pack-years: hazard ratio, 2.06; 95% confidence interval, 1.29-3.3) were significantly associated with incident HF hospitalization in comparison with never smoking. In blacks, cigarette smoking is an important risk factor for LV hypertrophy, systolic dysfunction, and incident HF hospitalization even after adjusting for effects on coronary heart disease. © 2018 American Heart Association, Inc.

    Full Text Available Abstract Background Recent emphasis has been placed on elucidating the biologic mechanism linking socioeconomic status (SES to cardiovascular disease (CVD. Positive associations of inflammatory biomarkers provide evidence suggestive of a biologic pathway by which SES may predispose to CVD. African Americans have disproportionately lower SES and have a higher prevalence of CVD risk factors compared to most ethnic/racial groups. Adiponectin (an anti-inflammatory marker is also lower. The objective of this study was to assess the association of adiponectin with SES among African American men and women using the Jackson Heart Study. Methods Study sample included 4340 participants. Linear regression was performed separately by SES and stratified by sex. Annual household income and level of education was used as proxies for SES. Crude, age, health behavior and health status adjusted models were analyzed. The main outcome was log-transformed adiponectin. Results Men in the lowest income group had significantly higher adiponectin than those in the highest income group in the fully adjusted model (ß/standard error [se], p value = .16/.08, p = .0008. Men with < high school level of education had significantly higher adiponectin in the crude and age adjusted models than those with ≥ college degree (.25/.05, p < .0001; .14/.05/ p = .005, respectively. Women with some college or vocational training in the crude and age adjusted models had lower adiponectin compared to women with ≥ college degree (−.09/.03, p = .004; −.06/.03, p = .04, respectively. Conclusion Findings suggest a potential inverse biologic pathway between annual household income and adiponectin among African American men. There was no such finding among women. Findings suggest interventions should be targeted for higher SES African American men to improve adiponectin levels.

    Several modifiable health behaviors and health factors that comprise the Life’s Simple 7, a cardiovascular health metric, have been associated with hypertension risk. We determined the association between cardiovascular health and incident hypertension in the Jackson Heart Study, a cohort of African-Americans. We analyzed participants without hypertension or cardiovascular disease at baseline (2000–2004) who attended ≥1 follow-up visit in 2005–2008 or 2009–2012 (n=1878). Body mass index, physical activity, diet, cigarette smoking, blood pressure, total cholesterol and fasting glucose were assessed at baseline and categorized as ideal, intermediate or poor using the American Heart Association’s Life’s Simple 7 definitions. Incident hypertension was defined at the first visit wherein a participant had systolic blood pressure≥140 mmHg, diastolic blood pressure≥90 mmHg or self-reported taking antihypertensive medication. There percentage of participants with ≤1, 2, 3, 4, 5 and 6 ideal Life’s Simple 7 components was 6.5%, 22.4%, 34.4%, 25.2%, 10.0% and 1.4%, respectively. No participants had 7 ideal components. During follow-up (median: 8.0 years), 944 (50.3%) participants developed hypertension, including 81.3% with ≤1 and 11.1% with 6 ideal components. The multivariable-adjusted hazard ratios (95% confidence interval) for incident hypertension comparing participants with 2, 3, 4, 5 and 6 versus ≤1 ideal component were 0.80 (0.61–1.03), 0.58 (0.45–0.74), 0.30 (0.23–0.40), 0.26 (0.18–0.37) and 0.10 (0.03–0.31), respectively (p-trendhypertension risk.

    Masked hypertension, defined as non-elevated clinic blood pressure and elevated out-of-clinic blood pressure may be an intermediary stage in the progression from normotension to hypertension. We examined the associations of out-of-clinic blood pressure and masked hypertension using ambulatory blood pressure monitoring with incident clinic hypertension in the Jackson Heart Study, a prospective cohort of African Americans. Analyses included 317 participants with clinic blood pressure hypertension was defined as mean daytime blood pressure ≥135/85mmHg; masked nighttime hypertension as mean nighttime blood pressure ≥120/70mmHg; and masked 24-hour hypertension as mean 24-hour blood pressure ≥130/80mmHg. Incident clinic hypertension, assessed at study visits in 2005–2008 and 2009–2012, was defined as the first visit with clinic systolic/diastolic blood pressure ≥140/90mmHg or antihypertensive medication use. During a median follow-up of 8.1 years, there were 187 (59.0%) incident cases of clinic hypertension. Clinic hypertension developed in 79.2% and 42.2% of participants with and without any masked hypertension, 85.7% and 50.4% with and without masked daytime hypertension, 79.9% and 43.7% with and without masked nighttime hypertension and 85.7% and 48.2% with and without masked 24-hour hypertension, respectively. Multivariable-adjusted hazard ratios (95% CI) of incident clinic hypertension for any masked hypertension and masked daytime, nighttime, and 24-hour hypertension were 2.13 (1.51–3.02), 1.79 (1.24–2.60), 2.22 (1.58–3.12), and 1.91 (1.32–2.75), respectively. These findings suggest that ambulatory blood pressure monitoring can identify African Americans at increased risk for developing clinic hypertension. PMID:27185746

    Full Text Available Os ancilostomatídeos são nematóides hematófagos parasitas do intestino delgado, podendo causar retardo no crescimento, inapetência, anorexia, apatia, anemia e até a morte. No homem, algumas espécies como Ancylostoma caninum, A. braziliense e A. tubaeforme podem causar larva migrans cutânea, quando as larvas infectantes de terceiro estágio penetram ativamente a pele íntegra. O objetivo deste trabalho foi detectar o parasitismo por ancilostomatídeos em fezes de cães domiciliados e assintomáticos na cidade de Campos dos Goytacazes, RJ, tendo em vista a proximidade do convívio destes animais com homem. Com esse propósito, amostras fecais de 68 cães foram coletadas, sendo trinta (44,12% considerados parasitados através de exame coproparasitológico utilizando-se o método de Willis-Molley.

    Once non-biodegradable, microplastics remain on the environment absorbing toxic hydrophobic compounds making them a risk to biodiversity when ingested or filtered by organisms and entering in the food chain. To evaluate the potential of the contamination by microplastics in mussels cultivated in Jurujuba Cove, Niterói, RJ, waters of three stations were collected during a rain and dry seasons using a plankton net and later filtered. Microplastics were quantified and characterized morphologically and chemically. The results showed a high concentration of microplastics in both seasons with diversity of colors, types and sizes. Synthetic polymers were present in all samples. The presence of microplastics was probably due to a high and constant load of effluent that this area receives and to the mussel farming activity that use many plastic materials. Areas with high concentrations of microplastics could not be used for mussel cultivation due to the risk of contamination to consumers. Copyright © 2016 Elsevier Ltd. All rights reserved.

    This work was conducted in the city of Campos dos Goytacazes/RJ, in which four residual soils collected in the region were technologically characterized. We sought to determine their properties, such as analysis of the colors after firing, aiming at its use in ceramic art. To this end the tests were conducted in the laboratories of the Universidade Estadual do Norte Fluminense Darcy Ribeiro (UENF) and that are granulometry (by sieving and sedimentation), specific mass of grains, chemical analysis by X-ray fluorescence, diffraction mineralogical identification X-ray, differential thermal analysis and thermogravimetry. The soils were analyzed before drying at 110 deg C and after burning the different temperatures (500 deg C 750 deg C and 950 deg C). The analyzed results showed the physical composition, chemical and mineralogical of raw material. After burning was possible to observe several color variations. (author)

    We investigated the diet and foraging of the endemic teiid lizard Cnemidophorus littoralis in a restinga habitat in Jurubatiba, Macaé - RJ. The stomach contents were removed, analyzed and identified to the Order level. There was no relationship between C. littoralis morphological variables and number, length or volume of preys. Termites (48.7%) and larvae (35.5%) were the most important prey items which occurred in the examined lizards' stomachs. The diet did not differ between males and females. Cnemidophorus littoralis is an active forager and predominantly consumes relatively sedentary prey or prey that is aggregated in the environment. We also found an intact and undigested hatchling of the crepuscular/nocturnal gekkonid lizard Hemidactylus mabouia in the stomach of an adult male of C. littoralis, which indicates that C. littoralis is a potential source of mortality for individuals of H. mabouia in the restinga de Jurubatiba.

  6. Sustainable Development Compromise[d] in the Planning of Metro Vancouver’s Agricultural Lands—the Jackson Farm Case

    Full Text Available This research provides analysis of the case of the Jackson Farm development application, embedded within the particular dynamics of the municipal, regional, and provincial sustainability land use policy culture of the Metro Vancouver region, in Canada. Within a culture of appreciation of the increasing need for sustainability in land use policy, including the protection of agricultural lands at the provincial level through the Agricultural Land Reserve (ALR, to urban intensification and protection of the green zone at the regional scale, lies a political conflict that comes into focus in individual land use decisions, within municipalities struggling for autonomy. This case is neither driven strictly by “the politics of the highest bidder” nor by policy failure; the case of the Jackson Farm is instead a case of the challenges of implementing inter-governmental coordination and collaborative governance in a context of both significant sustainability policy and urban growth. The process can be seen to follow an ecological modernization agenda, seeking “win–win” alternatives rather than recognizing that typical compromises, over time, may tip the direction of development away from sustainability policy goals. Understanding the twists, turns, and eventual compromise reached in the case of the Jackson Farm brings to light the implications of the shift in the regional planning culture which may necessitate a less flexible, more structured prioritization of competing goals within plans and policies in order to meet sustainability goals. We highlight this, and present an alternative implementation process within the existing policy regime with potential to aid the specific goal of agricultural land protection.

    1980-07-01

    The Jackson quadrangle covers a region largely within the Mississippi River flood plain. In the extreme northern Gulf Coastal Physiographic Province. Underlying Mesozoic and Cenozoic sediments of the Mississippi Embayment are relatively thick. Exposed sediments are largely Quaternary in age, though older Cenozoic material of both marine and nonmarine origin are exposed in areas adjacent to the flood plain in the east. A search of the available literature revealed no known uranium deposits. Seventy-three uranium anomalies were detected and are discussed briefly. None were considered significant, and most appeared to be of cultural origin. Magnetic data appears to be in agreement with existing structural interpretations of the region

    Full Text Available In this study, an attempt was made to simulate the air quality with reference to ozone over the Jackson (Mississippi region using an online WRF/Chem (Weather Research and Forecasting–Chemistry model. The WRF/Chem model has the advantages of the integration of the meteorological and chemistry modules with the same computational grid and same physical parameterizations and includes the feedback between the atmospheric chemistry and physical processes. The model was designed to have three nested domains with the inner-most domain covering the study region with a resolution of 1 km. The model was integrated for 48 hours continuously starting from 0000 UTC of 6 June 2006 and the evolution of surface ozone and other precursor pollutants were analyzed. The model simulated atmospheric flow fields and distributions of NO2 and O3 were evaluated for each of the three different time periods. The GIS based spatial distribution maps for ozone, its precursors NO, NO2, CO and HONO and the back trajectories indicate that all the mobile sources in Jackson, Ridgeland and Madison contributing significantly for their formation. The present study demonstrates the applicability of WRF/Chem model to generate quantitative information at high spatial and temporal resolution for the development of decision support systems for air quality regulatory agencies and health administrators.

  11. Quantitative Comparison of Ternary Eutectic Phase-Field Simulations with Analytical 3D Jackson-Hunt Approaches

    For the analytical description of the relationship between undercoolings, lamellar spacings and growth velocities during the directional solidification of ternary eutectics in 2D and 3D, different extensions based on the theory of Jackson and Hunt are reported in the literature. Besides analytical approaches, the phase-field method has been established to study the spatially complex microstructure evolution during the solidification of eutectic alloys. The understanding of the fundamental mechanisms controlling the morphology development in multiphase, multicomponent systems is of high interest. For this purpose, a comparison is made between the analytical extensions and three-dimensional phase-field simulations of directional solidification in an ideal ternary eutectic system. Based on the observed accordance in two-dimensional validation cases, the experimentally reported, inherently three-dimensional chain-like pattern is investigated in extensive simulation studies. The results are quantitatively compared with the analytical results reported in the literature, and with a newly derived approach which uses equal undercoolings. A good accordance of the undercooling-spacing characteristics between simulations and the analytical Jackson-Hunt apporaches are found. The results show that the applied phase-field model, which is based on the Grand potential approach, is able to describe the analytically predicted relationship between the undercooling and the lamellar arrangements during the directional solidification of a ternary eutectic system in 3D.

    This report examines the reactor coolant pump (RCP) seal operating experience through August 1990 at plants with Byron Jackson (B-J) RCPs. ne operating experience examined in this analysis included a review of the practice of continuing operation with a degraded seal. Plants with B-J RCPs that have had relatively good experience with their RCP seals attribute this success to a combination of different factors, including: enhanced seal QA efforts, modified/new seal designs, improved maintenance procedures and training, attention to detail, improved seal operating procedures, knowledgeable personnel involved in seal maintenance and operation, reduction in frequency of transients that stress the seals, seal handling and installation equipment designed to the appropriate precision, and maintenance of a clean seal cooling water system. As more plants have implemented corrective measures such as these, the number of B-J RCP seal failures experienced has tended to decrease. This study included a review of the practice of continued operation with a degraded seal in the case of PWR plants with Byron Jackson reactor coolant pumps. Specific factors were identified which should be addressed in order to safety manage operation of a reactor coolant pump with indications of a degrading seal

    The Saco do Mamangua is a narrow and elongated gulf located along the southeastern coast of Brazil, in the state of Rio de Janeiro (RJ). It is surrounded by high relieves, which form a peculiar environment called riá, with little river input and limited water exchange with the Atlantic Ocean. These features make the Saco do Mamangua an ideal environment to study sedimentary carbon cycling under well-constrained boundary conditions in order to investigate if tropical coastal environments serve dominantly as potential carbon sinks or sources. In this work we integrate geochemical data from marine sediments and pore waters in the Saco do Mamangua with mapping of benthic microbial communities, in order to unravel the biogeochemical carbon cycling linked to the production of biogenic methane. Our results reveal that carbon cycling occurs in two parallel pathways. The Saco do Mamangua receives organic carbon both by surface runoff and by primary production in the water column. A large part of this organic carbon is buried within the sediment resulting in the production of biogenic methane, which gives rise to methane seepages at the sea floor. These methane seeps sustain methanotrophic microbial communities in the sediment pore water, but also escapes into the atmosphere by ebullition. Consequently, the sediments of Saco do Mamangua acts simultaneously as carbon sink and carbon source. Future work will allow us to accurately quantify the actual carbon fluxes and calculate the net carbon balance in the local environment.

    Full Text Available Sanitation actions are rare in the communities of Manguinhos, so evaluation of the sanitary conditions of the river waters and the peridomestic soils of the communities allows the diagnosis of the risk of contamination. This study evaluated coliform levels (total coliforms and Escherichia coli by the filter membrane method, and parasitological (by adapted Lutz and Baermann-Moraes methods in the waters and soils of the Faria-Timbó, Jacaré and Canal do Cunha Rivers that pass through the communities of the Territory of Manguinhos, RJ, according to the standards established in Brazilian legislation. In all points of the rivers, the water was unfit, with an average level of Escherichia coli 3,800 times higher than that standardized in CONAMA Resolution No. 274/2000. Larvae, helminths eggs and protozoan oocysts were observed. Soil samples were also unfit, with mean total coliform level 77,000 times higher than that considered acceptable by SMAC Resolution 468/2010. The Escherichia coli average level was 53,000 times higher than that permitted by the legislation. However, helminths eggs were found in only one soil sample. It was concluded that the lack of sanitation in this locality results in the high coliform and parasitological levels of the river waters and in the peridomestic soils, and that immediate modifications are needed to the Brazilian environmental paradigm, which uses its water bodies as sewage disposal ditches.

    Full Text Available The purpose of this study was analyze the biometry of the mangrove crab, Ucides cordatus (L., 1763, captured commercially in the Gargaú Mangrove (RJ, comparing common practices with the demands of Law no 52/2003 of IBAM A – Brazilian Agency of Environment and Natural Resources – and making inferences about the fishing community’s perception of the species. From April 2002 to March 2003, 571 specimens were analyzed and the highest frequency of males and females was registered in a carapace width of 6,0 6,5cm. The exploration of the mangrove crab is conducted all year round and the gear known as “redinha” is used in its capture, disrespecting the abovementioned law. However, the capture excludes ovigerous females and small-sized specimens, which reflects the fishing community’s concerns about this resource. The exploitation of this crab population probably interferes in its growth pattern, and managerial action needs to be implemented, considering not only the recommendations of scientific studies, but also the local fishermen’s knowledge of the species.

    In many areas of the world, studies of marine debris are conducted with an emphasis on analyzing their composition, quantification and distribution on sandy beaches. However, in Brazil, studies are still restricted to some areas of the coast, and the quantities and the spatial and temporal patterns are unknown. To enhance the marine debris information in these areas, we selected the Itaipu and Itacoatiara beaches in Niterói, RJ, to collect, quantify and qualify the solid residues present in their sands. We collected 12 samples and recorded 118.39 kg of residues in Itaipu and 62.94 kg in Itacoatiara. At both beaches, the largest portion of debris was located on the upper part of the beach. Several debris items were related to food and drink consumption on the beaches, which indicated the contribution of beach users to pollution. Most of the debris was plastic. The greatest amount of debris was found at Itaipu in January and February and at Itacoatiara in January and March, months related to both the holiday season and abundant rainfall. The results demonstrated the necessity to implement an Environmental Education project for these areas to reduce its degradation. Copyright © 2015 Elsevier Ltd. All rights reserved.

    This paper aimed to characterize the anatomical structure of the wood of specimens of Mollinedia glabra (Spreng.) Perkins growing in two contiguous formations of restinga vegetation at Praia Virgem, in the municipality of Rio das Ostras, RJ. Both the Open Palmae (OPS) and the Sandy Strip Closed Shrub (SSCS) formations are found in coastal regions that receive between 1,100 and 1,300 mm of rainfall per year. Sapwood samples were collected in both formations. Typical anatomical features for this species include: solitary vessels, radial multiples or clusters elements, that are circular to angular in outline, 5-15 barred scalariform perforation plates, wood parenchyma scanty, septate fiber-tracheids, and wide multiseriate rays with prismatic crystals. Statistical analyses indicated a significant increase in the frequency of vessel elements and an increase in fiber-tracheid diameters in OPS individuals. These characteristics are considered structural adaptations to increased water needs caused by a greater exposure to sunlight. Continuous pruning may be responsible for the tyloses observed in OPS plants. The greater lengths and higher frequencies of the rays in SSCS trees may be due to the greater diameters of their branches. Our results suggest that M. glabra develops structural adaptations to the restinga micro-environmental variations during its development.

Já a eqüitatividade e diversidade de formigas nas amostras não foram influenciadas pela época da coleta. As amostras de formigas em galhos mortos adicionaram seis espécies à lista, acrescentando informações sobre a biologia das espécies. As amostras sobre plantas totalizaram 32 espécies de formigas, das quais 12 foram exclusivas, como as espécies de Pseudomyrmex e algumas de Crematogaster e Pachycondyla. Este estudo pretende contribuir para o desenvolvimento de prioridades conservacionistas em um dos ecossistemas mais ameaçados do mundo.Ants are an important functional component in tropical forest due to their ecological roles, biomass and species diversity. Although the Atlantic Forest is one of the best studied ecosystems in Brazil, there is a lack of information about ant diversity in forest fragments of the state of Rio de Janeiro. The composition and richness of the ant fauna from atlantic slope rain-forest in Marambaia island-RJ were assessed by the structured inventory in an area of 0.6 ha.

    Full Text Available This paper aimed to characterize the anatomical structure of the wood of specimens of Mollinedia glabra (Spreng. Perkins growing in two contiguous formations of restinga vegetation at Praia Virgem, in the municipality of Rio das Ostras, RJ. Both the Open Palmae (OPS and the Sandy Strip Closed Shrub (SSCS formations are found in coastal regions that receive between 1,100 and 1,300 mm of rainfall per year. Sapwood samples were collected in both formations. Typical anatomical features for this species include: solitary vessels, radial multiples or clusters elements, that are circular to angular in outline, 5-15 barred scalarifor perforation plates, ood parenchya scanty, septate fiber-tracheids, and wide multiseriate rays with prismatic crystals. Statistical analyses indicated a significant increase in the frequency of vessel elements and an increase in fiber-tracheid diameters in OPS individuals. These characteristics are considered structural adaptations to increased water needs caused by a greater exposure to sunlight. Continuous pruning may be responsible for the tyloses observed in OPS plants. The greater lengths and higher frequencies of the rays in SSCS trees ay be due to the greater diaeters of their branches. ur results suggest that . glabra develops structural adaptations to the restinga micro-environmental variations during its development.Este trabalho objetiva caracterizar a estrutura anatômica do lenho de Mollinedia glabra, ocorrente em duas formações vegetais contíguas na restinga da Praia Virgem, município de Rio das Ostras, RJ.

    Full Text Available The aim of this study was to describe and compare the succession of intertidal benthic communities in two areas at Guanabara Bay, RJ, Brazil: Urca, an area submitted to moderated organic pollution and Catalão, an extremely polluted area. Three transects in each area were scraped one month before the beginning of this study in order to evaluate the recruitment (recruitment-treatments. Three other transects were monitored without manipulation (monitoring treatments. Species composition and relative abundance were evaluated monthly between September and December, 2000. A total of 26 species was found at Urca and 13 at Catalão. The percent cover of the most abundant organisms was not similar between treatments at Urca after four months, while in Catalão, the similarity was 72% in the second month. The faster community development and recovery at the most polluted area was probably related to the existence of simple and resilient communities in more impacted areas.O objetivo deste estudo foi descrever e comparar a sucessão das comunidades bentônicas da região entre-marés, em duas áreas na Baía de Guanabara, RJ, Brasil: Urca, uma área sujeita a moderado nível de poluição orgânica, e Catalão, uma área extremamente poluída.

    Full Text Available The basic sanitation comprises several services that are essential to the maintenance of people's health and well-being. The populations that have an appropriate water supply, sewage collection and treatment, proper garbage disposal, among other services, are protected from diseases and have access to a minimum comfort to live in a safe way. In spite of the importance of these services, to the extent to be characterized as “basic”, several populations, national or worldwide, suffer for the lack or the complete privation of sanitation, live without access to quality water, their waste is thrown under open air and their garbage is disposed in inappropriate sites, what causes health and environmental impacts. This work is being accomplished in a community called Santa Cruz, located in Campos dos Goytacazes, RJ, and aims to carry out a survey about the local sanitary reality, especially about the quality of the water supplied to the population. 100 inhabitants of that community were interviewed and answered a questionnaire. Among the results, 22% of the interviewees consume the water that comes to their homes without any type of treatment, 47% consider the supply water as being of poor quality and 7% don't own home water tanks. After the interviews, bacteriological and physicochemical water analyses were performed in fifteen samples collected in the community. The test results indicated that the collected water was out of the drinking water standards, and therefore, inappropriate for human consumption.

    Full Text Available Dioctophyma renale é o maior nematóide conhecido. Seu parasitismo tem sido descrito em várias espécies animais e no homem. Este helminto localiza-se preponderantemente no rim direito ou livre na cavidade abdominal de seus hospedeiros. Sinais clínicos como abatimento, inapetência e emagrecimento podem estar associados à dioctofimose, apesar do curso da parasitose ser muitas vezes assintomático nos animais e pessoas infectadas. O único tratamento eficaz é a remoção cirúrgica do parasito e, em alguns casos, do rim afetado. O presente trabalho teve como objetivo relatar um caso de parasitismo por Dioctophyma renale em um cão no município de Valença/RJ. O animal foi resgatado por apresentar um tumor na pata e também hérnia perianal, mas ao caminho da policlínica veterinária apresentou também uma urina de odor fétido, que através da urinálise observou-se presença de ovos compatíveis com os de Dioctophyma renale.Dado o diagnóstico e localização do parasito, o animal foi encaminhado para a Policlínica de Pequenos Animais, da Faculdade de Medicina Veterinária de Valença, onde optou-se pela nefrectomia do rim afetado.

    Full Text Available Jabuticaba (Myrciariasp is a fruit native to the Atlantic Forest, belonging to the Myrtaceae family, and commonly found in Brazil. It presents considerable economic potential because it can be consumed as raw fruit or processed food. In Varre-Sai, RJ, jabuticaba is strongly used in the industrialization of alcoholic beverages. The production of fermented alcoholic alternative is used to avoid waste, and make the most of the considerable nutritional value of the fruit. The content of anthocyanins in jabuticaba ranges from 310 and 315mg/100g, relatively high value compared to other fruits considered rich in antioxidants. Therefore, sensory analyses of jabuticaba alcoholic beverages produced in Varre-Sai can improve the quality of the product and potential sales. Given that the part of jabuticaba rich in phenolic compounds is the bark, the whole use of the fruit is the best alternative to take advantage of its benefits. Sensory analysis evaluated the acceptance of fermented alcoholic of Jabuticaba, in relation to its overall rating attributes, color, flavor and aroma, based on a 9-point hedonic scale, with ends named strongly disliked (1 and strongly liked (9; as well as purchase intention of tasters by a 5-point hedonic scale, with anchor points would certainly buy (5 and would not certainly buy (1. The results showed that the products had good acceptance and the fermented Sweet Tinto was rated best in all attributes, obtaining 90.18% frequency in the acceptance of hedonic scale, with respect to global acceptance. Even in the hypothetical situation of purchase, it received 74.5% of the votes in the good range of the scale. This shows that the alcoholic fermented beverages may be an alternative for the consumption of antioxidants, and that their production can improve the income of farmers as well as help avoid fruit wasting.

    Maywood Chemical Works (MCW) of Maywood, New Jersey, generated process wastes and residues associated with the production and refining of thorium and thorium compounds from monazite ores from 1916 to 1956. MCW supplied rare earth metals and thorium compounds to the Atomic Energy Commission and various other government agencies from the late 1940s to the mid-1950s. Area residents used the sandlike waste from this thorium extraction process mixed with tea and cocoa leaves as mulch in their yards. Some of these contaminated wastes were also eroded from the site into Lodi Brook. At the request of the US Department of Energy (DOE), a group from Oak Ridge National Laboratory conducts investigative radiological surveys of properties in the vicinity of MCW to determine whether a property is contaminated with radioactive residues, principally 232 Th, derived from the MCW site. The surveys typically include direct measurement of gamma radiation levels and soil sampling for radionuclide analyses. The survey of this commercial property at Route 17(S) and Becker Avenue, Rochelle Park, New Jersey (RJ001), was conducted in 1986. Measurements taken at the commercial property located at Route 17(S) and Becker Avenue indicate slightly elevated gamma exposure rates in three areas of the parking lot. Although results of analysis of the asphalt disclosed radionuclide concentrations in excess of the applicable criterion, their presence is due to naturally radioactive substances in asphalt patching materials and is not associated with material from the MCW site. Therefore, it is recommended that this site be eliminated from consideration for inclusion in the DOE remedial action program. 5 refs., 2 figs., 3 tabs

    Full Text Available No Brasil atual, o turbulento contexto político, econômico e social tem sido terra fértil para o exame das práticas de gestão. Assim, o presente artigo tem por propósito investigar a realidade socioeconômica no município de Quissamã (RJ em conexão com a expansão dos recursos financeiros advindos do petróleo, que abasteceram os cofres públicos a partir de 1997. Para tanto, fez-se revisão bibliográfica e análise quantitativa de dados, fruto de pesquisa a documentos públicos da prefeitura. Nesta etapa, foram identificados os mecanismos de gestão e aplicação dos recursos originados no petróleo, como principais promotores do desenvolvimento local. Adicionalmente, foi estabelecida análise comparada entre Quissamã (RJ e o município vizinho Conceição de Macabu (RJ, visto que estes mantêm características territoriais e demográficas semelhantes. A despeito de Conceição não receber recursos do petróleo nos patamares de Quissamã, apresentou melhores índices de desenvolvimento. De resultado, verificou-se aumento da concentração de renda e a constatação de que os recursos públicos não geraram benefícios mais estruturantes para a população. Acredita-se que o debate proposto possa contribuir para o aperfeiçoamento das ações governamentais, restando salientar a necessidade de se aprofundar o que ora se discute, estabelecendo-se novos caminhos, num processo de melhoria da gestão de recursos públicos.

    Full Text Available Resilience, as a property of social-ecological systems, is related to the ability of such systems to adapt and deal with perturbations. This study examined the characteristics in a community of artisanal fishermen, using some of the resilience indicators (flexibility, capacity to organize and capacity to learn. The flexibility indicator represents the economic dependence on the natural resource; the capacity to organize indicator informs about participation in decision-making and in community organizations; and the capacity to learn indicator refers to the perception of environmental alterations in relation to human activity. Together, these indicators can inform about the adaptive capacity of the community and its relationship with resource management. Semi structured interviews were conducted in the months of January, April, July and August of 2012 in the community of Praia Grande and surroundings (Paraty/RJ (n=22. As to the flexibility indicator, 59.1% of the fishermen interviewed have another source of income, being tourism the main activity among them (36.4%. Most of the fishermen (77.2% use more than one type of fishing technique which may either reduce pressure on the fishing resource or have an opposite effect, if it is the case of the use of more intensive techniques, such as trawling. Regarding the fishermen’s capacity to organize, it was found and discussed the low participation on decision-making regarding fishing, especially because the area of the study is situated in a context of social-environmental conflicts with conservation areas. As for the capacity to learn, the results indicate that the fishermen perceive the human activity as an agent responsible for the perturbations in the natural environment, and they suggest different solutions in face of the decrease of each target species. Through the use of the resilience indicators it was possible to identify the attributes that allow the adaptation of the community to

Este trabalho objetivou avaliar a riqueza e abundância da fauna edáfica, bem como sua distribuição vertical, em área de restinga periodicamente inundada na Ilha da Marambaia, RJ, em duas épocas distintas, verão (chuvosa e inverno (seca. Foram coletadas 10 amostras de serapilheira e de solo na profundidade de 0-5 cm, em que foram feitas extrações da fauna por meio de extratores do tipo Berlese-Tüllgren. Observou-se aumento da abundância da fauna edáfica do período seco para o chuvoso, enquanto a riqueza de grupos taxonômicos não foi modificada. Em ambas as épocas, os grupos de maior ocorrência foram Formicidae e Collembola. Quanto à distribuição vertical, verificou-se a preferência dos organismos pelo compartimento serapilheira, no período chuvoso, e pelo solo, no período seco. A microfagia e a saprofagia representaram as principais formas de utilização dos recursos alimentares, seguidos da predação, sugerindo melhor estruturação do habitat no ecossistema. Além disso, a ocorrência de grupos que só são percebidos em ambientes não perturbados indica que o ecossistema de restinga da Ilha da Marambaia, no momento em que foi avaliado, ano de 2002, encontrava-se pouco ou nada degradado e em bom estado de conservação.

    2017-12-01

    Full Text Available The article analyses Michael Jackson’s album Thriller and Prince’s movie Purple Rain. We explore their camp aesthetics and their recasting of the cultural representations of the black male. Jackson’s and Prince’s performative personas are both liberatory and burdened with the received cultural scripts of black masculinity. We claim that their employment of camp is political rather than escapist and depoliticized. Camp serves them as a platform to mourn the cultural displacement of the black male body in a postslavery America. In particular, the two artists distance themselves from the extensive ideological and physical pressures exerted on the black male body in the early 1980s. As a result, their performances are complexly de-Oedipalized. Prince in Purple Rain refuses to assume the patriarchal position of the Father. Analogously, Jackson fashions himself as a Peter Pan-like eternal adolescent who never makes his final identification as either heterosexual or LGBTQ desiring agent. In the coda to the article, we reach beyond the 1980s to explore a more flexible approach to camp in the artistic output of twenty-first-century African American performers of Queercore and Afrofuturist scenes, which were partially enabled by Jackson’s and Prince’s performances.

    Both environmental and genetic factors play important roles in the development of metabolic syndrome (MetS). Studies about its associated factors and genetic contribution in African Americans (AA) are sparse. Our aim was to report the prevalence, associated factors and heritability estimates of MetS and its components in AA men and women. Data of this cross-sectional study come from a large community-based Jackson Heart Study (JHS). We analysed a total of 5227 participants, of whom 1636 from 281 families were part of a family study subset of JHS. Participants were classified as having MetS according to the Adult Treatment Panel III criteria. Multiple logistic regression analysis was performed to isolate independently associated factors of MetS (n=5227). Heritability was estimated from the family study subset using variance component methods (n=1636). About 27% of men and 40% of women had MetS. For men, associated factors with having MetS were older age, lower physical activity, higher body mass index, and higher homocysteine and adiponectin levels (pmetabolism playing a central role in the development of MetS and encourage additional efforts to identify the underlying susceptibility genes for this syndrome in AA.

    Full Text Available This study sought to establish the psychometric properties of a Coping Strategies Inventory Short Form (CSISF by examining coping skills in the Jackson Heart Study cohort. We used exploratory and confirmatory factor analysis, Pearson’s correlation, and Cronbach Alpha to examine reliability and validity in the CSI-SF that solicited responses from 5302 African American men and women between the ages of 35 and 84. One item was dropped from the 16-item CSI-SF, making it a 15-item survey. No significant effects were found for age and gender, strengthening the generalizability of the CSI-SF. The internal consistency reliability analysis revealed reliability between alpha = 0.58-0.72 for all of the scales, and all of the fit indices used to examine the CSI-SF provided support for its use as an adequate measure of coping. This study provides empirical support for utilizing this instrument in future efforts to understand the role of coping in moderating health outcomes.

    The 3500 lignite seam at the Gibbons Creek Mine in Grimes County, TX was sampled for pollen and spores at 10 cm intervals. The majority of samples are dominated (to 60%) by Momipites from the Juglandaceae (walnut family), as is typical of Jackson Group sediments. Other palynomorph taxa vary systematically, with a peak of pollen of the freshwater tree Nyssa (blackgum) and associated Rboipites angustus (to 17%) occurring at the base. Higher in the seam, increase (to 55%) of Cupuliferoipollenites (a chestnut-like grain) and Cyrillaceae-pollenites? ventosus (to 7%) percentages may indicate a higher salinity environment. A Chrysophyllum (satin leaf) peak (to 25%) near the top of the seam suggests relatively shallow fresh-water conditions. Core samples from an interval above the lignites represent a transgressive-regressive cycle in inner shelf clastics. These samples were taken at 40 cm or greater intervals and reveal the regional pollen flora. Although minor changes occur, palynomorph spectra are for the most part homogenous. The dominant grain is again Momipites coryloides, but in general percentages are lower (to 35%). Cupuliferoipollenites (to 17%), Chrysophyllum (to 5%), and Rhoipites angustus (to 3%) are not less important, but do not peak as they do in the lignite spectra. Palm leaf megafossils; in one sample suggest a clastic wetland; in this sample palm pollen (mostly Arecipites, representing the modern saw palmetto) reaches 73%. Another sample contains high (26%) percentages of the fern spore Lygodiumsporites adriennis. High percentages of these two taxa do not occur in the lignite samples.

    Objective We examined associations between neighborhood socioeconomic disadvantage, perceived neighborhood safety and cardiometabolic risk factors, adjusting for health behaviors and socioeconomic status (SES) among African Americans. Methods Study participants were non-diabetic African Americans (n = 3,909) in the baseline examination (2000–2004) of the Jackson Heart Study. We measured eight risk factors: the metabolic syndrome, its five components, insulin resistance and cardiovascular inflammation. We assessed neighborhood socioeconomic disadvantage with US Census 2000 data. We assessed perceived neighborhood safety, health behaviors and SES via survey. We used generalized estimating equations to estimate associations with a random intercept model for neighborhood effects. Results After adjustment for health behaviors and SES, neighborhood socioeconomic disadvantage was associated with the metabolic syndrome in women (PR 1.13, 95% CI 1.01, 1.27). Lack of perceived safety was associated with elevated glucose (OR 1.36, 95% CI 1.03, 1.80) and waist circumference (PR 1.06, 95% CI 1.02, 1.11) among women, and with elevated glucose (PR 1.30, 95% CI 1.02, 1.66) and insulin resistance (PR 1.25, 95% CI 1.08, 1.46) among men. Conclusions Neighborhood socioeconomic disadvantage and perceived safety should be considered as targets for intervention to reduce cardiometabolic risks among African Americans. PMID:23691005

    This paper studies the joint optimization problem of energy and delay in a multi-hop wireless network. The optimization variables are the transmission rates, which are adjustable according to the packet queueing length in the buffer. The optimization goal is to minimize the energy consumption of energy-critical nodes and the packet transmission delay throughout the network. In this paper, we aim at understanding the well-known decentralized algorithms which are threshold based from a different research angle. By using a simplified network model, we show that we can adopt the semi-open Jackson network model and study this optimization problem in closed form. This simplified network model further allows us to establish some significant optimality properties. We prove that the system performance is monotonic with respect to (w.r.t.) the transmission rate. We also prove that the threshold-type policy is optimal, i.e., when the number of packets in the buffer is larger than a threshold, transmit with the maximal rate (power); otherwise, no transmission. With these optimality properties, we develop a heuristic algorithm to iteratively find the optimal threshold. Finally, we conduct some simulation experiments to demonstrate the main idea of this paper.

    Full Text Available Abstract Background Adiponectin, paradoxically reduced in obesity and with lower levels in African Americans (AA, modulates several cardiometabolic risk factors. Because abdominal visceral adipose tissue (VAT, known to be reduced in AA, and subcutaneous adipose tissue (SAT compartments may confer differential metabolic risk profiles, we investigated the associations of VAT and SAT with serum adiponectin, separately by gender, with the hypothesis that VAT is more strongly inversely associated with adiponectin than SAT. Methods Participants from the Jackson Heart Study, an ongoing cohort of AA (n = 2,799; 64% women; mean age, 55 ± 11 years underwent computer tomography assessment of SAT and VAT volumes, and had stored serum specimens analyzed for adiponectin levels. These levels were examined by gender in relation to increments of VAT and SAT. Results Compared to women, men had significantly lower mean levels of adiponectin (3.9 ± 3.0 μg/mL vs. 6.0 ± 4.4 μg/mL; p 3 vs. 2,668 ± 968 cm3; p 3 vs. 801 ± 363 cm3; p  Conclusion In African Americans, abdominal visceral adipose tissue had an inverse association with serum adiponectin concentrations only among women. Abdominal subcutaneous adipose tissue appeared as a protective fat depot in men.

    Mississippi has some of the most pronounced racial disparities in HIV infection in the country; African Americans comprised 37% of the Mississippi population but represented 80% of new HIV cases in 2015. Improving outcomes along the HIV care continuum, including linking and retaining more individuals and enhancing adherence to medication, may reduce the disparities faced by African Americans in Mississippi. Little is understood about clergy's views about the HIV care continuum. We assessed knowledge of African American pastors and ministers in Jackson, Mississippi about HIV and the HIV care continuum. We also assessed their willingness to promote HIV screening and biomedical prevention technologies as well as efforts to enhance linkage and retention in care with their congregations. Four focus groups were conducted with 19 African American clergy. Clergy noted pervasive stigma associated with HIV and believed they had a moral imperative to promote HIV awareness and testing; they provided recommendations on how to normalize conversations related to HIV testing and treatment. Overall, clergy were willing to promote and help assist with linking and retaining HIV positive individuals in care but knew little about how HIV treatment can enhance prevention or new biomedical technologies such as pre-exposure prophylaxis (PrEP). Clergy underscored the importance of building coalitions to promote a collective local response to the epidemic. The results of this study highlight important public health opportunities to engage African American clergy in the HIV care continuum in order to reduce racial disparities in HIV infection.

    Full Text Available Cardiovascular disease (CVD, including heart failure, is a major cause of morbidity and mortality, particularly among African Americans. Exposure to ambient air pollution, such as that produced by vehicular traffic, is believed to be associated with heart failure, possibly by impairing cardiac function. We evaluated the cross-sectional association between residential proximity to major roads, a marker of long-term exposure to traffic-related pollution, and echocardiographic indicators of left and pulmonary vascular function in African Americans enrolled in the Jackson Heart Study (JHS: left ventricular ejection fraction, E-wave velocity, isovolumic relaxation time, left atrial diameter index, and pulmonary artery systolic pressure. We examined these associations using multivariable linear or logistic regression, adjusting for potential confounders. Of 4866 participants at study enrollment, 106 lived <150 m, 159 lived 150–299 m, 1161 lived 300–999 m, and 3440 lived ≥1000 m from a major roadway. We did not observe any associations between residential distance to major roads and these markers of cardiac function. Results were similar with additional adjustment for diabetes and hypertension, when considering varying definitions of major roadways, or when limiting analyses to those free from cardiovascular disease at baseline. Overall, we observed little evidence that residential proximity to major roads was associated with cardiac function among African Americans.

    To explore viral marketing strategies for Eclipse cigarettes used by the RJ Reynolds Company (Winston-Salem, North Carolina, USA). Analysis of previously secret tobacco industry documents and multimedia materials. The failure of RJ Reynolds' (RJR) 1988 "smokeless" cigarette, Premier, was in part due to widespread bad word of mouth about the product's flavour, quality and difficulty of use. In 1994 RJR introduced an updated version of Premier, the ostensibly "reduced risk" Eclipse cigarette. RJR developed viral marketing channels to promote Eclipse using (1) exploratory interviews to motivate consumers to spread the word about Eclipse prior to market release, (2) promotional videos featuring positive feedback from test group participants to portray majority consensus among triers, (3) "Tupperware"-like parties for Eclipse where participants received samples to pass around in their social circles and (4) the Eclipse website's bulletin board as a forum for potential users to discuss the brand in their own words. These strategies targeted the brand's likeliest adopters, recruited informal and credible representatives of the product unaffiliated with RJR, and controlled the information spread about the product. Viral marketing techniques may be particularly useful to promote new tobacco products such as Eclipse that have limited appeal and need a highly motivated audience of early adopters and acceptors. Such techniques help evade the mass rejection that could follow mass promotion, circumvent marketing restrictions, and allow tobacco companies to benefit from health claims made by consumers. Cigarette manufacturers must be held accountable for perceived health benefits encouraged by all promotional activities including viral marketing.

    Full Text Available O objetivo deste trabalho foi fazer a caracterização morfométrica a partir de alguns parâmetros físicos da bacia hidrográfica do rio Debossan, Nova Friburgo, RJ. Para isso, gerou-se inicialmente o Modelo Digital de Elevação Hidrologicamente Consistente (MDEHC a partir de cartas topográficas do IBGE, na escala 1:50.000, utilizando o sistema de informações geográficas, através dos softwares ArcVIEW e Arc/INFO. A partir do MDEHC, foram calculados alguns parâmetros morfométricos para o estudo do comportamento hidrológico da bacia. A área de drenagem encontrada foi de 9,9156 km² e o perímetro, de 17,684 km. A bacia hidrográfica do rio Debossan tem formato alongado, coeficiente de compacidade de 1,5842, fator de forma de 0,3285 e índice de circularidade de 0,3985. A densidade de drenagem obtida para a bacia foi de 2,3579 km/km². A forma mais alongada da bacia hidrográfica indica que a precipitação pluviométrica sobre ela se concentra em diferentes pontos, concorrendo para amenizar a influência da intensidade de chuvas, as quais poderiam causar maiores variações da vazão do curso d'água.The objective of this work was to perform a morphometric characterization based on some physical parameters. In order to do so, a Hydrologically Consistent Digital Elevation Model (HCDEM was generated from IBGE topographical maps, scale 1:50.000, using as database and analysis the system of geographic information, by means of the ArcVIEW and Arc/INFO version 8.3 systems. From this, some morphometric parameters of a previous study on the hydrologic behavior of the watershed were calculated. The drainage area was 9,9156 Km² and 17,684 km in perimeter. The Debossan river watershed was proven not easily subject to floods as the compacity coefficient was far from the unit (1.5842 and its shape factor presented a low value (0.3285. Such fact can still be proven by the circularity index value (0.3985. The drainage density was 2,3579 Km

    Subjective social status has been shown to be inversely associated with multiple cardiovascular risk factors, independent of objective social status. However, few studies have examined this association among African Americans and the results have been mixed. Additionally, the influence of discrimination on this relationship has not been explored. Using baseline data (2000-2004) from the Jackson Heart Study, an African American cohort from the U.S. South (N=5301), we quantified the association of subjective social status with selected cardiovascular risk factors: depressive symptoms, perceived stress, waist circumference, insulin resistance and prevalence of diabetes. We contrasted the strength of the associations of these outcomes with subjective versus objective social status and examined whether perceived discrimination confounded or modified these associations. Subjective social status was measured using two 10-rung "ladders," using the U.S. and the community as referent groups. Objective social status was measured using annual family income and years of schooling completed. Gender-specific multivariable linear and logistic regression models were fit to examine associations. Subjective and objective measures were weakly positively correlated. Independent of objective measures, subjective social status was significantly inversely associated with depressive symptoms (men and women) and insulin resistance (women). The associations of subjective social status with the outcomes were modest and generally similar to the objective measures. We did not find evidence that perceived racial discrimination strongly confounded or modified the association of subjective social status with the outcomes. Subjective social status was related to depressive symptoms but not consistently to stress or metabolic risk factors in African Americans. Copyright © 2012 Elsevier Ltd. All rights reserved.

    The concept of ideal cardiovascular health (CVH), defined by the American Heart Association primarily for coronary heart disease and stroke prevention, may apply to diabetes mellitus prevention among blacks. Our sample included 2668 adults in the Jackson Heart Study with complete baseline data on 6 of 7 American Heart Association CVH metrics (body mass index, healthy diet, smoking, total cholesterol, blood pressure, and physical activity). Incident diabetes mellitus was defined as fasting glucose ≥126 mg/dL, physician diagnosis, use of diabetes mellitus drugs, or glycosylated hemoglobin ≥6.5%. A summary CVH score from 0 to 6, based on presence/absence of ideal CVH metrics, was derived for each participant. Cox regression was used to estimate adjusted hazard ratios. Mean age was 55 years (65% women) with 492 incident diabetes mellitus events over 7.6 years (24.6 cases/1000 person-years). Three quarters of participants had only 1 or 2 ideal CVH metrics; no participant had all 6. After adjustment for demographic factors (age, sex, education, and income) and high-sensitivity C-reactive protein, each additional ideal CVH metric was associated with a 17% diabetes mellitus risk reduction (hazard ratio, 0.83; 95% CI, 0.74-0.93). The association was attenuated with further adjustment for homeostasis model assessment for insulin resistance (hazard ratio, 0.89; 95% CI, 0.79-1.00). Compared with participants with 1 or no ideal CVH metric, diabetes mellitus risk was 15% and 37% lower in those with 2 and ≥3 ideal CVH metrics, respectively. The AHA concept of ideal CVH is applicable to diabetes mellitus prevention among blacks. These associations were largely explained by insulin resistance. © 2017 The Authors.

    Blood pressure (BP) can differ substantially when measured in the clinic versus outside of the clinic setting. Few population-based studies with ambulatory blood pressure monitoring (ABPM) include African Americans. We calculated the prevalence of clinic hypertension and ABPM phenotypes among 1,016 participants in the population-based Jackson Heart Study, an exclusively African-American cohort. Mean daytime systolic BP was higher than mean clinic systolic BP among participants not taking antihypertensive medication (127.1[standard deviation 12.8] versus 124.5[15.7] mmHg, respectively) and taking antihypertensive medication (131.2[13.6] versus 130.0[15.6] mmHg, respectively). Mean daytime diastolic BP was higher than clinic diastolic BP among participants not taking antihypertensive medication (78.2[standard deviation 8.9] versus 74.6[8.4] mmHg, respectively) and taking antihypertensive medication (77.6[9.4] versus 74.3[8.5] mmHg, respectively). The prevalence of daytime hypertension was higher than clinic hypertension for participants not taking antihypertensive medication (31.8% versus 14.3%) and taking antihypertensive medication (43.0% versus 23.1%). A high percentage of participants not taking and taking antihypertensive medication had nocturnal hypertension (49.4% and 61.7%, respectively), white coat hypertension (30.2% and 29.3%, respectively), masked hypertension (25.4% and 34.6%, respectively), and a non-dipping BP pattern (62.4% and 69.6%, respectively). In conclusion, these data suggest hypertension may be misdiagnosed among African Americans without using ABPM. PMID:28285829

    Both genomics and environmental stressors play a significant role in increases in blood pressure (BP). In an attempt to further explain the hypertension (HTN) disparity among African Americans (AA), both genetic underpinnings (selected candidate genes) and stress due to perceived racial discrimination (as reported in the literature) have independently been linked to increased BP among AAs. Although Gene x Environment interactions on BP have been examined, the environmental component of these investigations has focused more on lifestyle behaviors such as smoking, diet, and physical activity, and less on psychosocial stressors such as perceived discrimination.The present study uses candidate gene analyses to identify the relationship between Everyday Discrimination (ED) and Major Life Discrimination (MLD) with increases in systolic BP (SBP) and diastolic BP (DBP) among AA in the Jackson Heart Study. Multiple linear regression models reveal no association between discrimination and BP after adjusting for age, sex, body mass index (BMI), antihypertensive medication use, and current smoking status.Subsequent candidate gene analysis identified 5 SNPs (rs7602215, rs3771724, rs1006502, rs1791926, and rs2258119) that interacted with perceived discrimination and SBP, and 3 SNPs (rs2034454, rs7602215, and rs3771724) that interacted with perceived discrimination and DBP. Most notably, there was a significant SNP × discrimination interaction for 2 SNPs on the SLC4A5 gene: rs3771724 (MLD: SBP P = .034, DBP P = .031; ED: DBP: P = .016) and rs1006502 (MLD: SBP P = .034, DBP P = .030; ED: DBP P = .015).This study supports the idea that SNP × discrimination interactions combine to influence clinically relevant traits such as BP. Replication with similar epidemiological samples is required to ascertain the role of genes and psychosocial stressors in the development and expression of high BP in this understudied population.

    Abnormal diurnal blood pressure (BP), including nondipping patterns, assessed using ambulatory BP monitoring, have been associated with increased cardiovascular risk among white and Asian adults. We examined the associations of BP dipping patterns (dipping, nondipping, and reverse dipping) with cardiovascular target organ damage (left ventricular mass index and left ventricular hypertrophy), among participants from the Jackson Heart Study, an exclusively black population-based cohort. Analyses included 1015 participants who completed ambulatory BP monitoring and had echocardiography data from the baseline visit. Participants were categorized based on the nighttime to daytime systolic BP ratio into 3 patterns: dipping pattern (≤0.90), nondipping pattern (>0.90 to ≤1.00), and reverse dipping pattern (>1.00). The prevalence of dipping, nondipping, and reverse dipping patterns was 33.6%, 48.2%, and 18.2%, respectively. In a fully adjusted model, which included antihypertensive medication use and clinic and daytime systolic BP, the mean differences in left ventricular mass index between reverse dipping pattern versus dipping pattern was 8.3±2.1 g/m 2 ( P pattern versus dipping pattern was -1.0±1.6 g/m 2 ( P =0.536). Compared with participants with a dipping pattern, the prevalence ratio for having left ventricular hypertrophy was 1.65 (95% CI, 1.05-2.58) and 0.96 (95% CI, 0.63-1.97) for those with a reverse dipping pattern and nondipping pattern, respectively. In this population-based study of blacks, a reverse dipping pattern was associated with increased left ventricular mass index and a higher prevalence of left ventricular hypertrophy. Identification of a reverse dipping pattern on ambulatory BP monitoring may help identify black at increased risk for cardiovascular target organ damage. © 2017 The Authors.

    In 2011, the mountainous region of the State of Rio de Janeiro (Brazil) suffered enormous social and economic losses due to thousands of landslides caused by an extreme rainfall event. The mapping of the scars of these landslides in an area of 421 km2 in the municipality of Nova Friburgo, RJ - Brazil resulted in a total of 3622, and 89% of these scars were located in areas covered by grasses and forests. Despite the unexpected result (64% of scars in forest areas), field evidence has shown that most of the forest fragments in the municipality are in the initial stages of succession and in different states of degradation, evidencing the need for a better understanding of the role of these forests in the detonation and propagation of landslides. Two slope forest areas with different ages (20 and 50 years) were evaluated in relation to the vegetative aspects that influence the stability of the slopes in each area. Hydrological monitoring, including precipitation, interception by manual and automatic method, soil moisture and subsurface flows were performed in two different areas: forest and grass. Soil moisture was monitored by granular matrix sensors and flows by collecting troughs in trenches at depths of 0 cm, 20 cm, 50 cm, 100 cm, 150 cm and 220 cm, which were also analyzed for biomass and length of thick roots (> 2 mm diameter) and thin roots (particle size, aggregate stability, porosity and hydraulic conductivity in situ). In the grass area, the lower soil structure in relation to the forest areas makes it difficult to transmit the water through the soil matrix. During the monitoring period, that area preserved the moisture in depths of 100 cm, 150 cm and 220 cm. The fasciculate root system of the grasses increased the infiltration of water at the top of the soil, favouring the formation of more superficial saturation zones in the heavy rains, due to the hydraulic discontinuities. In forest areas, infiltration by preferential paths allows the concentration of

    Full Text Available The gekkonid lizard Hemidactylus mabouia is an exotic species in Brazil and is found in different ecosystems. This species was recorded at Ilha Grande, RJ, one of the largest insular remains of the Atlantic Rainforest in Brazil. In this study, the occurrence of H. mabouia was determined throughout the island, including the rain forest, restinga and anthropic environments. We used the active search method in points along 19 trails that surround Ilha Grande. At each regular interval of 100 m, we searched for the presence of H. mabouia. The species was recorded in a total of 100 points among the 719 sampled and, in all cases, the occurrence of the lizard corresponded to points located in anthropic or perianthropic areas. As most of Ilha Grande is covered by dense tropical rain forest, we believe this has restricted the invasion of H. mabouia in natural environments within the island.

    On the 20th of March 2007 a large rock avalanche fell on Morsárjökull, one of the outlet glaciers from the southern part of the Vatnajökull ice cap, in south Iceland. This is considered to be one of the largest rock avalanches which have occurred in Iceland during the last decades. It is believed that it fell in two separate stages, the main part fell on the 20th of March and the second and smaller one, on the 17th of April 2007. The Morsárjökull outlet glacier is about 4 km long and surrounded by up to 1000 m high valley slopes. The outlet glacier is fed by two ice falls which are partly disconnected to the main ice cap of Vatnajökull, which indicates that the glacier is mainly fed by ice avalanches. The rock avalanche fell on the eastern side of the uppermost part of the Morsárjökull outlet glacier and covered about 1/5 of the glacier surface, an area of about 720,000 m2. The scar of the rock avalanche is located on the north face of the headwall above the uppermost part of the glacier. It is around 330 m high, reaching from about 620 m up to 950 m, showing that the main part of the slope collapsed. It is estimated that about 4 million m3 of rock debris fell on the glacier, or about 10 million tons. The accumulation lobe is up to 1.6 km long, reaching from 520 m a.s.l., to about 350 m a.s.l. Its width is from 125 m to 650 m, or on average 480 m. The total area which the lobe covers is around 720.000 m2 and its mean thickness 5.5 m. The surface of the lobe shows longitudinal ridges and grooves and narrow flow-like lobes, indicating that the debris mass evolved down glacier as a mixture of a slide and debris flow. The debris mass is coarse grained and boulder rich. Blocks over 5 to 8 m in diameter are common on the edges of the lobe up to 1.6 km from the source. No indication was observed of any deformation of the glacier surface under the debris mass. The first glaciological measurements of Morsárjökull outlet glacier were carried out in the year 1896

    Growth in sodium chloride (NaCl) is known to induce stress in non-halophilic microorganisms leading to effects on the microbial metabolism and cell structure. Microorganisms have evolved a number of adaptations, both structural and metabolic, to counteract osmotic stress. These strategies are well-understood for organisms in NaCl-rich brines such as the accumulation of certain organic solutes (known as either compatible solutes or osmolytes). Less well studied are responses to ionic environments such as sulfate-rich brines which are prevalent on Earth but can also be found on Mars. In this paper, we investigated the global metabolic response of the anaerobic bacterium Yersinia intermedia MASE-LG-1 to osmotic salt stress induced by either magnesium sulfate (MgSO4) or NaCl at the same water activity (0.975). Using a non-targeted mass spectrometry approach, the intensity of hundreds of metabolites was measured. The compatible solutes L-asparagine and sucrose were found to be increased in both MgSO4 and NaCl compared to the control sample, suggesting a similar osmotic response to different ionic environments. We were able to demonstrate that Yersinia intermedia MASE-LG-1 accumulated a range of other compatible solutes. However, we also found the global metabolic responses, especially with regard to amino acid metabolism and carbohydrate metabolism, to be salt-specific, thus, suggesting ion-specific regulation of specific metabolic pathways.

    Objective To explore viral marketing strategies for Eclipse cigarettes used by the RJ Reynolds Company (Winston-Salem, North Carolina, USA). Methods Analysis of previously secret tobacco industry documents and multimedia materials. Results The failure of RJ Reynolds’ (RJR) 1988 “smokeless” cigarette, Premier, was in part due to widespread bad word of mouth about the product’s flavour, quality and difficulty of use. In 1994 RJR introduced an updated version of Premier, the ostensibly “reduced risk” Eclipse cigarette. RJR developed viral marketing channels to promote Eclipse using (1) exploratory interviews to motivate consumers to spread the word about Eclipse prior to market release, (2) promotional videos featuring positive feedback from test group participants to portray majority consensus among triers, (3) “Tupperware”-like parties for Eclipse where participants received samples to pass around in their social circles and (4) the Eclipse website’s bulletin board as a forum for potential users to discuss the brand in their own words. These strategies targeted the brand’s likeliest adopters, recruited informal and credible representatives of the product unaffiliated with RJR, and controlled the information spread about the product. Conclusions Viral marketing techniques may be particularly useful to promote new tobacco products such as Eclipse that have limited appeal and need a highly motivated audience of early adopters and acceptors. Such techniques help evade the mass rejection that could follow mass promotion, circumvent marketing restrictions, and allow tobacco companies to benefit from health claims made by consumers. Cigarette manufacturers must be held accountable for perceived health benefits encouraged by all promotional activities including viral marketing. PMID:18332064

    African Americans are at high risk for chronic kidney disease (CKD). Obesity may increase the risk for CKD by exacerbating features of the metabolic syndrome and promoting glomerular hyperfiltration. Whether other factors also affecting these pathways may amplify or mitigate obesity-CKD associations has not been investigated. We studied interactions between obesity and these candidate factors in 2043 African Americans without baseline kidney disease enrolled in the Jackson Heart Study. We quantified obesity as body mass index (BMI), sex-normalized waist circumference and visceral adipose volume measured by abdominal computed tomography at an interim study visit. Interactions were hypothesized with (i) metabolic risk factors (dietary quality and physical activity, both quantified by concordance with American Heart Association guidelines) and (ii) factors exacerbating or mitigating hyperfiltration (dietary protein intake, APOL1 risk status and use of renin-angiotensin system blocking medications). Using multivariable regression, we evaluated associations between obesity measures and incident CKD over the follow-up period, as well as interactions with metabolic and hyperfiltration factors. Assessed after a median of 8 years (range 6-11 years), baseline BMI and waist circumference were not associated with incident CKD. Higher visceral adipose volume was independently associated with incident CKD (P   =   0.008) in a nonlinear fashion, but this effect was limited to those with lower dietary quality (P   =   0.001; P-interaction = 0.04). In additional interaction models, higher waist circumference was associated with greater risk of incident CKD among those with the low-risk APOL1 genotype (P   =   0.04) but not those with a high-risk genotype (P-interaction = 0.02). Other proposed factors did not modify obesity-CKD associations. Higher risks associated with metabolically active visceral adipose volume and interactions with dietary quality suggest

    Few studies have examined the impact of lifecourse socioeconomic position (SEP) on cardiovascular disease (CVD) risk among African Americans. We used data from the Jackson Heart Study (JHS) to examine the associations of multiple measures of lifecourse SEP with CVD events in a large cohort of African Americans. During a median of 7.2-year follow-up, 362 new or recurrent CVD events occurred in a sample of 5301 participants aged 21 to 94. Childhood SEP was assessed by using mother's education, parental home ownership, and childhood amenities. Adult SEP was assessed by using education, income, wealth, and public assistance. Adult SEP was more consistently associated with CVD risk in women than in men: age-adjusted hazard ratios for low versus high income (95% CIs), 2.46 (1.19 to 5.09) in women and 1.50 (0.87 to 2.58) in men, P for interaction=0.1244, and hazard ratio for low versus high wealth, 2.14 (1.39 to 3.29) in women and 1.06 (0.62 to 1.81) in men, P for interaction=0.0224. After simultaneous adjustment for all adult SEP measures, wealth remained a significant predictor of CVD events in women (HR=1.73 [1.04, 2.85] for low versus high). Education and public assistance were less consistently associated with CVD. Adult SEP was a stronger predictor of CVD events in younger than in older participants (HR for high versus low summary adult SEP score 3.28 [1.43, 7.53] for participants ≤50 years, and 1.90 (1.36 to 2.66) for participants >50 years, P for interaction 0.0846). Childhood SEP was not associated with CVD risk in women or men. Adult SEP is an important predictor of CVD events in African American women and in younger African Americans. Childhood SEP was not associated with CVD events in this population. © 2015 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley Blackwell.

E-mail: jairopinheirodasilva@gmail.com Toxoplasma gondii is a protozoan parasite that infects up to a third of the world's population. Infection is mainly acquired by ingestion of food or water that is contaminated with oocysts shed by cats or by eating undercooked or raw meat containing tissue cysts and by blood transfusion or organ transplantation. Primary infection is usually subclinical but in some patients cervical lymphadenopathy or ocular disease can be present. Infection acquired during pregnancy may cause severe damage to the fetus. In immunocompromised patients, reactivation of latent disease can cause life-threatening encephalitis. Diagnosis of toxoplasmosis can be established by direct detection of the parasite or by serological techniques. The aim of the present study was verify the seroprevalence of toxoplasmosis in cornea donors of Rio de Janeiro, Brazil. IgM and IgG anti- T. gondii antibodies were investigated in 426 sera of corneal donors by using the indirect fluorescent antibody test (IFAT and immunoenzymatic assay (ELISA techniques. The participants were selected by convenience sampling. Demographic information of study subjects including their gender, age, cause of death and home region were recorded. Out of 426 serum samples, 338 (79.34% and 17 (3.99% were positive regarding anti-T. gondii IgG and IgM antibodies ELISA

    Full Text Available This paper deals with the evolution of the judicial interpretation of the term“ interstate commerce” beginning with the enactment the Sherman Anti-Trust Act of 1890 and concluding with the Supreme Court’s US. v. Darby decision some 51 years later. As may be recalled, the Fuller Court’s 1895 ruling in E.C. Knight all but destroyed Sherman and allowed most corporate monopolies free reign going into the early twentieth century. Even after Sherman’s revival in Northern Securities, however, the Court’s narrow interpretation of “interstate commerce” continued to effectively thwart federal attempts at economic regulation for the next half century. This paper examines the formulation of the so-called “Greene Doctrine” and its author, future Supreme Court Justice Howell Edmunds Jackson as well as their ultimate impact on American constitutional and economic history.

    In 1994, an apparent outbreak of atypical genital ulcers was noted by clinicians at the sexually transmitted disease clinic in Jackson, Mississippi. Of 143 patients with ulcers tested with a multiplex polymerase chain reaction (PCR) assay, 56 (39%) were positive for Haemophilus ducreyi, 44 (31%) for herpes simplex virus, and 27 (19%) for Treponema pallidum; 12 (8%) were positive for > 1 organism. Of 136 patients tested for human immunodeficiency virus (HIV) by serology, 14 (10%) were HIV-seropositive, compared with none of 200 patients without ulcers (P chancroid were significantly more likely than male patients without ulcers to report sex with a crack cocaine user, exchange of money or drugs for sex, and multiple sex partners. The strong association between genital ulcers and HIV infection in this population highlights the urgency of preventing genital ulcers in the southern United States.

    We describe the clinical and radiological manifestations of the Jackson-Weiss syndrome (JWS) in a large South Australian kindred. Radiological abnormalities not previously described in the hands include coned epiphyses, distal and middle phalangeal hypoplasia, and carpal bone malsegmentation. New radiological findings in the feet include coned epiphyses, hallux valgus, phalangeal, tarso-navicular and calcaneo-navicular fusions, and uniform absence of metatarsal fusions. Absence of linkage to eight markers along the short arm of chromosome 7 excluded allelian between JWS and Saethre-Chotzen syndrome at 7p21. No linkage was detected to D5S211, excluding allelism to another recently described cephalosyndactyly syndrome mapping to 5qter. 35 refs., 5 figs., 4 tabs.

    Digital vascular tone and function, as measured by peripheral arterial tonometry (PAT), are associated with cardiovascular risk and events in non-Hispanic whites. There are limited data on relations between PAT and cardiovascular risk in African-Americans. PAT was performed on a subset of Jackson Heart Study participants using a fingertip tonometry device. Resting digital vascular tone was assessed as baseline pulse amplitude. Hyperemic vascular response to 5 minutes of ischemia was expressed as the PAT ratio (hyperemic/baseline amplitude ratio). Peripheral augmentation index (AI), a measure of relative wave reflection, also was estimated. The association of baseline pulse amplitude (PA), PAT ratio, and AI to risk factors was assessed using stepwise multivariable models. The study sample consisted of 837 participants from the Jackson Heart Study (mean age, 54 ± 11 years; 61% women). In stepwise multivariable regression models, baseline pulse amplitude was related to male sex, body mass index, and diastolic blood pressure (BP), accounting for 16% of the total variability of the baseline pulse amplitude. Age, male sex, systolic BP, diastolic BP, antihypertensive medication, and prevalent cardiovascular disease contributed to 11% of the total variability of the PAT ratio. Risk factors (primarily age, sex, and heart rate) explained 47% of the total variability of the AI. We confirmed in our cohort of African-Americans, a significant relation between digital vascular tone and function measured by PAT and multiple traditional cardiovascular risk factors. Further studies are warranted to investigate the utility of these measurements in predicting clinical outcomes in African-Americans.

    Compared to whites, insulin-resistant African Americans have worse outcomes. Screening programs that could identify insulin resistance early enough for intervention to affect outcome often rely on triglyceride (TG) and high-density lipoprotein cholesterol (HDL-C) levels. Racial differences in TG and HDL-C may compromise the efficacy of these programs in African Americans. A recommendation currently exists to use the TG/HDL-C ratio ≥2.0 to predict insulin resistance in African Americans. The validity of this recommendation needs examination. Therefore, our aim was to determine the ability of TG/HDL-C ratio to predict insulin resistance in African Americans. In 1,903 African Americans [895 men, 1,008 women, age 55 ± 12 years, mean ± standard deviation (SD), range 35-80 years, body mass index (BMI) 31.0 ± 6.4 kg/m(2), range 18.5-55 kg/m(2)] participating in the Jackson Heart Study, a population-based study of African Americans, Jackson, Mississippi tricounty region, insulin resistance was defined by the upper quartile (≥4.43) of homeostasis model assessment of insulin resistance (HOMA-IR). An area under the receiver operating characteristic curve (AUC-ROC) of >0.70 was required for prediction of insulin resistance by TG/HDL-C. The optimal test cutoff was determined by the Youden index. HOMA-IR was similar in men and women (3.40 ± 2.03 vs. 3.80 ± 2.46, P = 0.60). Women had lower TG (94 ± 49 vs. 109 ± 65 mg/dL P Heart Study can help determine the efficacy of screening programs in African-Americans.

    The redox cycling of manganese has pronounced effects on the adsorption of trace elements onto oxide surfaces is leaving these unavailable for the biota. Specific constants for the kinetics oxidation reaction of Mn in mangrove ecosystems have been measured. Water samples with different characteristics were collected in a tidal creek in a mangrove forest growth at Itacuruca, RJ. The methodology used to study the kinetics was, incubation of the water, in laboratory, with Mn-54. The oxides precipitates were filtered at constant intervals of time. The Mn-54 decay on the filters and filtrates were counted, for 600 s, in HPGe and associated electronics ORTEC. Ln A x t diagram showed an autocatalytic kinetic behavior. Temperature, pH, O{sub 2} dissolved, salinity, Mn (II) and Mn (IV) were appraised. The rate constant k{sup '}{sub 1}1 varied from 1,0 x 10{sup -5} to 4,0 x 10{sup -5} s{sup -1}. The k{sup '}{sub 2} rate constant had a larger variation, according to the other kinetic model that shows more of a heterogeneous affect, or catalysis via bacteria. We found a mean half life for Mn(II) of 12 h for the homogeneous kinetics in the mangrove. Rate constants increased with the pH, temperature, O{sub 2} dissolved, tide height, and decrease with salinity. (author)

  2. Potential bird dispersers of Psychotria in a area of Atlantic forest on Ilha Grande, RJ, Southeastern Brazil: a biochemical analysis of the fruits

    Full Text Available The present study assessed the fruiting pattern, bird foraging behavior, and sugar content of ripe fruits of two sympatric species of Rubiaceae (Psychotria brasiliensis and P. nuda. This study was carried out in an Atlantic forest area on Ilha Grande, RJ, between August 1998 and July 1999. Fruit production occurred year round, with a peak of mature P. brasiliensis fruits in December 1998 and another of P. nuda in February of 1999. Lipaugus lanioides (Cotingidae, Baryphtengus ruficapillus (Momotidae and Saltator similis (Emberizidae made the most frequent foraging visits to fruiting P. brasiliensis, so that L. lanioides and B. ruficapillus removed the fruits with sallying maneuvers while S. similis gleaned the fruits. Lipaugus lanioides was by far the most important consumer, and potentially the main disperser of P. brasiliensis. Birds of this genus are heavy frugivores in the tropical forests and are widely assumed to be important seed dispersers. The fruits were analyzed quantitatively and qualitatively in relation to the amounts of sucrose and starch. Psychotria brasiliensis (the visited species showed the smallest quantity of sucrose and the highest amount of starch. These findings suggest that what may influence the birds' choice of fruit is the proportion of starch in the Psychotria species studied here rather than the carbohydrate composition.

    Polonium-210 ( 210 Po), a short-lived member from the uranium series, is broadly distributed in Nature being among all alpha-emitters the major contributor to the internal dose in man. Studies of diets have shown that marine foods are important sources of this radionuclide. The levels of 210 Po have been determined in three highly consumed marine species, the fishes Sardinella brasiliensis (sardine) and Thunnus atlanticus (tuna), and the shrimp Litopenaeus brasiliensis, purchased from the Niteroi (RJ, Brazil) fish market, and caught along the coast of the state of Rio de Janeiro. Doses of 210 Po were determined for the entire organisms and for some tissues and organs, such as eyes, heart, gills, muscle, stomach liver, intestine and pyloric caecal (fishes) or eyes, head content, exoskeleton, muscle, hepatopancreas and pleopods. 210 Po is not uniformly distributed within these species, the highest levels being observed for sardine in the intestine (1634.6 mBq g-1), tuna in pyloric caecal (4656.1 mBq g-1) and shrimp in the hepatopancreas (1460.5 mBq g-1). The 210 Po activities in sardine, tuna and shrimp, calculated on a mean whole-organism basis, were 64.6, 34.5 and 39.5 Bq kg-1 (dry weight) respectively, with corresponding concentration factors of 7.2 x104, 3.8 x104 and 4.4 x104. Considering body distribution, almost 60% of the total activity is concentrated in the pyloric caecal of both fishes and in the hepatopancreas of the shrimp. In turn, the edible parts concentrate much less activity. (author)

    Studies around the management and disposal of radioactive waste have been conducted for decades. In Brazil, the National Nuclear Energy Commission (CNEN) is responsible for Intermediate Radioactive Waste deposits, located in Fundao Island, Rio de Janeiro (RJ). According to CNEN 8.01 norm, it is necessary to characterize and to study the location area around the deposit. Within this context, the objective of this study was to characterize the Canal Cunha Basin, the western of Guanabara Bay and study the Environmental Impact, with determination of heavy metals (Pb, Cu, Cd, Zn and Ni) in said river basin and bay. The work involves collecting water and sediment samples in five georeferenced points. The sediment samples was collected using the EPA Method 3051 and the reading of the concentrations of heavy metals in water and sediment was performed by ICP-OES. Maps were generated for characterization and spatial distribution of these metals on Canal Cunha Basin. The Canal Cunha's drainage composes a territory with 62.85 km{sup 2} (approximated area) and 37.01 km of perimeter The high occupancy rates in the urban area that decrease the rate of infiltration and changes in physiography caused by construction of embankments because a reverse behavior expected, which increases the runoff coefficient of 0.74. The results show that in periods of high river discharge, there is a drift of large amounts of Pb, Cu and Cd to the waters of the Canal Cunha and Guanabara Bay. Zn and Ni presented higher concentrations in the dry season. The Pb, Cu, Cd, Zn and Ni concentrations are smaller than the concentrations found in the sediment. This probably happens because Cunha Canal Basin and western of Guanabara Bay receive high organic load, and also because of the high percentage of fine sediment in this, thus promoting the adsorption of metals, not contaminating the water and thus not reaching the food chain.

    In vitro interaction of benthic algae from the Angra dos Reis region, R.J., Brazil, was studied with critical radionuclides to be released in the liquid effluent of CNAAA (unit I). 137 Cs- 60 Co - and 125 I uptake and loss by Sargassum filipendula, Padina Vickersiae and Acanthophora Spicifera were observed. Biological half-lives and bioaccumulation factors (B.F.) were estimated. Co and I uptake were fast (apparent equilibrium in 3 to 7 days). Cs uptake was slower (2 to 3 weeks). Loss followed an inverse pattern (fast for Cs, slow for Co and I). B.F. ranged from 10 1 for Cs, to 10 3 for I and 10 3 -10 4 for Co. Higher B.F. for Co and I were found for P. vickersiae (up to 1,4 X 10 4 ) an A. spicifera (up to 7 X 10 3 ) respectively. These species represent important potential media for the transference of Co-I-and-to a much lesser extent - Cs isotopes, through food-webs. They exhibited high capacity to compete with local sandy sediments for the retention of Co and I. High B.F., rapid uptake and moderate to long biological half-lives enable S. filipendula, P. vickersiae and A. specifera to be powerful aids in the monitoring of radioactive contamination by Co and I isotopes. Since the majority of marine organisms tends to exhibit Cs B.F. similars to those reported here, these algae may also be used as monitors for Cs isotopes, the low B.F. being compensated by their abundance, wide distribution and facility of collection.

    Polonium-210 ({sup 210}Po), a short-lived member from the uranium series, is broadly distributed in Nature being among all alpha-emitters the major contributor to the internal dose in man. Studies of diets have shown that marine foods are important sources of this radionuclide. The levels of {sup 210}Po have been determined in three highly consumed marine species, the fishes Sardinella brasiliensis (sardine) and Thunnus atlanticus (tuna), and the shrimp Litopenaeus brasiliensis, purchased from the Niteroi (RJ, Brazil) fish market, and caught along the coast of the state of Rio de Janeiro. Doses of {sup 210}Po were determined for the entire organisms and for some tissues and organs, such as eyes, heart, gills, muscle, stomach liver, intestine and pyloric caecal (fishes) or eyes, head content, exoskeleton, muscle, hepatopancreas and pleopods. {sup 210}Po is not uniformly distributed within these species, the highest levels being observed for sardine in the intestine (1634.6 mBq g-1), tuna in pyloric caecal (4656.1 mBq g-1) and shrimp in the hepatopancreas (1460.5 mBq g-1). The {sup 210}Po activities in sardine, tuna and shrimp, calculated on a mean whole-organism basis, were 64.6, 34.5 and 39.5 Bq kg-1 (dry weight) respectively, with corresponding concentration factors of 7.2 x104, 3.8 x104 and 4.4 x104. Considering body distribution, almost 60% of the total activity is concentrated in the pyloric caecal of both fishes and in the hepatopancreas of the shrimp. In turn, the edible parts concentrate much less activity. (author)

    Full Text Available The aim of this study was to evaluate litter input and decomposition and root biomass of three forest fragments at different successional stages (advanced, medium and initial in Pinheiral Municipality, in the state of RJ, Brazil. To evaluate litter input, 10 conic collectors were installed in each fragment. The root biomass was quantified by monolith method in two periods (wet and dry at depths of 0-10, 10-20 and 20- 30 cm, and 10 samples were collected in each area. To evaluate the decomposition rate in each area, 12 litter bags were distributed. No significant differences were observed for litter input between the areas, but there was a tendency to increase litter input with successional evolution. No significant differences were observed for seasonal litter input between areas during the year, but there was a small increase in the months of July and August. At the advanced stage, litter input could be grouped into two periods: February to July, with lower values; and August to January, with higher values. The leaf fractions and reproductive material input were reduced, while branch and other fractions increased with succession. For litter decomposition, the intermediate stage showed the lowest decomposition constant (k (0.0038 g g -1day-1 and the highest half life time (182 days , followed by the initial (0044 g g -1day-1 and 154 days and advanced (0.0064 g g -1day-1 and 108 days stages. The root biomass in different areas and depths for both two periods studied showed higher values in the advanced stage, followed by the intermediate stage and the lowest values were found in the initial stage. The seasonal root biomass difference occurred mainly in the intermediate stage, with higher values in June.

    Full Text Available A região noroeste fluminense conta com um importante arranjo produtivo local no setor de beneficiamento de rochas ornamentais e de revestimento. Essa atividade é responsável por boa parte da renda local, empregando muitas pessoas. O principal produtor da região é o município de Santo Antônio de Pádua/RJ, que possui 154 empresas (78 pedreiras e 76 serrarias. A grande atividade de extração e beneficiamento das rochas vem causando na região problemas ambientais, pois durante as etapas de produção muito se perde devido a técnicas rudimentares e a deficiência no tratamento dos efluentes, o que acaba gerando impactos ao Rio Pomba, onde estes são lançados. O objetivo deste trabalho de pesquisa foi realizar um diagnóstico do uso da água no processo produtivo e a partir daí avaliar as diferentes alternativas para se ter um consumo otimizado e um tratamento dos efluentes a fim de minimizar os danos ambientais. Foram realizados alguns estudos de casos de caráter exploratório, pesquisas bibliográficas, entrevistas com proprietários, funcionários e profissionais ligadas ao setor de rochas e visitas técnicas a empresas da região. Os resultados apontam para uma falta de preparo e conhecimento técnico dos empresários e funcionários ao uso de novas tecnologias aliadas às questões ambientais no que se refere ao tratamento e consumo de água, principalmente para as pequenas empresas.

    Full Text Available A Região Oceânica do município de Niterói (RJ tem sido objeto de intensa especulação imobiliária nas últimas décadas, associando o ideário de paisagens naturais e qualidade de vida a um modelo de habitações predominantemente voltado para população de alto padrão aquisitivo. Neste sentido, este trabalho objetiva analisar a expansão tanto do perímetro urbano como da densidade de domicílios da região no período entre 1976 e 2010, associando ainda a situação atual com o zoneamento urbano-ambiental vigente. A análise histórica, a geoestatística e um conjunto variado de geotecnologias foram as principais ferramentas utilizadas para produção e análise de dados. Em conjunto com estas ferramentas, é proposta uma metodologia alternativa de tratamento de dados censitários e avaliação de densidades de domicílios por unidade de área. Os resultados demonstram o crescimento de 112% da área urbanizada da Região Oceânica, enquanto o número de domicílios cresceu na ordem de 600%, remontando ao processo interligado de avanço tanto via expansão em área quanto via aumento de densidade. Em comparação com o zoneamento, há esgotamento para incorporação de novas áreas perimetrais, o que aponta para um aprofundamento ainda maior do aumento de densidades demográficas nas próximas décadas assim como da pressão sobre os geossistemas costeiros.

    Gay and bisexual men and other men who have sex with men (MSM) account for more than two thirds of new HIV infections in the U.S., with Black MSM experiencing the greatest burden. Antiretroviral pre-exposure prophylaxis (PrEP) can reduce MSM's vulnerability to HIV infection. Uptake of PrEP has been limited, particularly among racial and ethnic minority MSM. Four semi-structured focus groups with gay and bisexual men and other MSM at risk for HIV infection were convened in Boston and Jackson in late 2013. The analysis plan utilized a within-case, across-case approach to code and analyze emerging themes, and to compare results across the two cities. Participants recruited in Jackson were primarily Black gay men, while Boston participants were mostly non-Hispanic White gay men. Participants in both sites shared concerns about medication side effects and culturally insensitive health care for gay men. Jackson participants described stronger medical mistrust, and more frequently described experiences of anti-gay and HIV related stigma. Multiple addressable barriers to PrEP uptake were described. Information about side effects should be explicitly addressed in PrEP education campaigns. Providers and health departments should address medical mistrust, especially among Black gay and bisexual men and other MSM, in part by training providers in how to provide affirming, culturally competent care. Medicaid should be expanded in Mississippi to cover low-income young Black gay and bisexual men and other MSM.

    Direct Push Technology (DPT) and a modified-auger method of sampling were used at an abandoned wood-preserving plant site at Jackson, Tennessee, to collect lithologic data and ground-water samples in an area known to be affected by a subsurface creosote plume. The groundwater samples were analyzed using (1) gas chromatography with photo-ionization detection (GS/PID), (2) high- performance liquid chromatography (HPLC), (3) colonmetric phenol analysis, and (4) toxicity bioassay. DPT piezocone and cone-penetrometer-type tools provided lithologic data and ground-water samples at two onsite stations to a depth of refusal of about 35 feet below land surface. With the assistance of an auger rig, this depth was extended to about 65 feet by pushing the tools in advance of the augers. Following the DPT work, a modified-auger method was tested by the USGS. This method left doubt as to the integrity of the samples collected once zones of contamination were penetrated. GC/PID and HPLC methods of water-quality analysis provided the most data concerning contaminants in the ground-water and proved to be the most effective in creosote plume detection. Analyses from these methods showed that the highest concentrations of contaminants were detected at depths less than about 35 feet below land surface. Phenol analyses provided data supplemental to the HPLC analyses. Bioassay data indicated that toxicity associated with the plume extended to depths of about 55 feet below land surface.

    Borehole geophysical logs and flowmeter data were collected in April 2011 from eight boreholes to identify the depth and orientation of cavernous zones within the Miocene Tampa Limestone in the vicinity of Jim Woodruff Lock and Dam in Jackson County, Florida. These data are used to assess leakage near the dam. Each of the eight boreholes was terminated in limestone at depths ranging from 84 to 104 feet. Large cavernous zones were encountered in most of the borings, with several exceeding 20-inches in diameter. The cavernous zones generally were between 1 and 5 feet in height, but a cavern in one of the borings reached a height of about 6 feet. The resistivity of limestone layers penetrated by the boreholes generally was less than 1,000 ohm-meters. Formation resistivity near the cavernous zones did not show an appreciable contrast from surrounding bedrock, probably because the bedrock is saturated, owing to its primary permeability. Measured flow rates in the eight boreholes determined using an electromagnetic flowmeter were all less than ±0.1 liter per second. These low flow rates suggest that vertical hydraulic gradients in the boreholes are negligible and that hydraulic head in the various cavernous zones shows only minor, if any, variation.

    The acid-base buffer capacity before and after the treatment with the Mehra-Jackson and Tamm reagents was assessed by continuous potentiometric titration for the main genetic horizons of two profiles of podzolic soils in the Central Forest State Reserve. The total buffer capacity was calculated in the pH range from the initial titration point (ITP) to 3 for the acid titration and from the ITP to 10 for the base titration, as well as the buffer capacities in the pH intervals of 0.25. It was found that both treatments abruptly decreased the base buffer capacity, which reached 70-90% in the E horizons. The high direct linear correlation of the difference between the total base buffer capacities before and after each treatment with the content of Fe in the Tamm extract was revealed. From the results obtained, a conclusion was drawn that finely dispersed Fe hydroxides were the main solid-phase constituents ensuring the base buffer capacity, and the deprotonation of hydroxyl groups on the surface of Fe hydroxides was the essential buffer reaction during the base titration.

    Malignant pleural effusion (MPE) is a common clinical problem in patients with advanced cancer and portends a poor prognosis, which means survival of less than six months. In June 1997, the US-FDA approved an indwelling TPC with a one-way drainage valve to be used in the management of MPE. Although popularity of this TPC has increased over the past few years, the experience with this device remains limited in Thai patients. One of the reasons is its high cost. Assess the efficacy and the safety of customary indwelling TPC by using Jackson drain in the management of patients with symptomatic MPE. Ten patients with symptomatic MPE were receiving these catheters (18 Fr Silicone catheters with 25 cm fenestrated length) to drain effusion via plastic vacuum bottles (250 ml) every other day or as needed to relieve dyspnea. The patient's dyspnic respiration, quality of life, and comfort during the catheter's application were quantified with a Borg score, the St. George Respiratory Disease Questionnaire (SGRQ), and the comfort's score, respectively. These parameters were recorded at initial (before insertion) and 2-week follow-up visit. Pain after 24 hours of each insertion was quantified by visual pain analogue scale (VPAS). Patients were followed until either death or catheter removal. The Borg score, SGRQ, and comfort's score showed significant improvement at 2-week visit (p drain was effective in the treatment of MPE as a TPC without early complications.

    Full Text Available Background: Wilson disease (WD is characterized by hepatic copper accumulation with progressive liver damage to cirrhosis. This study aimed to characterize the toxic milk mouse from The Jackson Laboratory (Bar Harbor, ME, USA (tx-j mouse model of WD according to changes over time in hepatic copper concentrations, methionine metabolism, global DNA methylation, and gene expression from gestational day 17 (fetal to adulthood (28 weeks. Methods: Included liver histology and relevant biochemical analyses including hepatic copper quantification, S-adenosylmethionine (SAM and S-adenosylhomocysteine (SAH liver levels, qPCR for transcript levels of genes relevant to methionine metabolism and liver damage, and DNA dot blot for global DNA methylation. Results: Hepatic copper was lower in tx-j fetuses but higher in weanling (three weeks and adult tx-j mice compared to controls. S-adenosylhomocysteinase transcript levels were significantly lower at all time points, except at three weeks, correlating negatively with copper levels and with consequent changes in the SAM:SAH methylation ratio and global DNA methylation. Conclusion: Compared to controls, methionine metabolism including S-adenosylhomocysteinase gene expression is persistently different in the tx-j mice with consequent alterations in global DNA methylation in more advanced stages of liver disease. The inhibitory effect of copper accumulation on S-adenosylhomocysteinase expression is associated with progressively abnormal methionine metabolism and decreased methylation capacity and DNA global methylation.

    Full Text Available Garfield produces a critique of minimalist art practice by demonstrating how the artist Melanie Jackson’s Some things you are not allowed to send around the world (2003 and 2006 and the experimental film-maker Vivienne Dick’s Liberty’s booty (1980 – neither of which can be said to be about feeling ‘at home’ in the world, be it as a resident or as a nomad – examine global humanity through multi-positionality, excess and contingency, and thereby begin to articulate a new cosmopolitan relationship with the local – or, rather, with many different localities – in one and the same maximalist sweep of the work. ‘Maximalism’ in Garfield’s coinage signifies an excessive overloading (through editing, collage, and the sheer density of the range of the material that enables the viewer to insert themselves into the narrative of the work. In the art of both Jackson and Dick Garfield detects a refusal to know or to judge the world; instead, there is an attempt to incorporate the complexities of its full range into the singular vision of the work, challenging the viewer to identify what is at stake.

    Calculating the (a,c) ring of the maximal phase orbifold for `invertible' Landau--Ginzburg models, we show that the Berglund--H"ubsch construction works for all potentials of the relevant type. The map that sends a monomial in the original model to a twisted state in the orbifold representation of the mirror is constructed explicitly. Via this map, the OP selection rules of the chiral ring exactly correspond to the twist selection rules for the orbifold. This shows that we indeed arrive at th...

    Industrial accidents generally endanger structures and the set of environmental influence area where the enterprises are located, especially when affected by atmospheric dispersion of their pollutants, whose concern with the evacuation of the population is the main goal in emergency situations. Considering the nuclear complex Angra dos Reis - RJ, based on computer modeling analysis of the mechanisms of pollutant dispersion in conjunction with geographic information systems were developed. Thus, information about the dispersion of radionuclides - from simulations performed on the HYSPLIT; meteorological data (direction, intensity and calm on the wind regime and analysis of the wind field in the region using WRF), occurrence of landslides and data on the environmental study area were integrated into a GIS database using ArcGIS platform. Aiming at the identification and definition of escape routes in case of evacuation from accidental events in CNAAA, the results point solutions for long-term planning, based on weather and landslides, and short-term, supported by simulations of the dispersion radionuclides, in order to support actions that assist local emergency planning.

Atualmente, segundo dados do Censo do IBGE (2010,  existem 463.731 pessoas, sendo que o índice de envelhecimento corresponde a 12% da população total. Este segmento etário está aumentando e configura um desenho demográfico que refletirá nos próximos anos em uma maior população idosa. A investigação partiu de uma pesquisa bibliográfica sobre a questão principal que é o envelhecimento populacional. A pesquisa caracteriza-se como de natureza quantitativa. Levando em consideração o objetivo proposto, tem caráter descritivo e exploratório, na qual foram utilizados dados obtidos dos Censos Demográficos e dos Indicadores Sociais do IBGE, do período de 1991 a 2015. Como resultado, pode-se perceber que o crescimento e o envelhecimento demográfico da população indicam  um fenômeno relevante que vem modificando a perspectiva de vida dos indivíduos. O grande desafio que se coloca para a sociedade contemporânea envolve o reconhecimento do ser enquanto sujeito de direitos, dos princípios de independência, participação, dignidade, assistência e autorrealização estabelecidos pela ONU.

    Full Text Available Nos últimos anos, a importância do profissional farmacêutico tem aumentada, se tornando fundamental para uma eficiente promoção, proteção e recuperação da saúde do paciente. Um dos principais motivos para a valorização da profissão foi a facilidade de aquisição de medicamentos pela população, o que levava os mesmos ao uso incorreto dos fármacos. A satisfação da população é um fator vital pra a determinação de qualidade do serviço farmacêutico. O objetivo do trabalho é identificar os pontos críticos das atividades farmacêuticas, assim tornando-os visíveis e com isso facilitando a melhora na atuação do farmacêutico. Para que o objetivo fosse visualizado, foram distribuídos 131 questionários a população de Miracema-RJ, que continham 12 itens sobre as atividades farmacêuticas para serem avaliados quanto à satisfação e importância. Através dessas avaliações foram obtidas as médias e os erros-padrão de cada item, como também o déficit de satisfação. Os dados foram apresentados em forma de gráfico, para uma melhor compreensão dos resultados. O principal gráfico do trabalho é o de quadrante, pois ele separa os pontos críticos as serem mudados. Esses pontos foram: prescrição farmacêutica; nebulização; descarte de medicamento vencido. O trabalho ajudará na analise critica com o intuito de melhoria nos serviços farmacêuticos, assim diminuindo o uso incorreto de medicamento.

    Full Text Available Este trabalho avalia a viabilidade técnica e econômica de se implantar um sistema de coleta de águas pluviais em uma instituição de ensino e uma residência, ambas localizadas no município de Campos dos Goytacazes, RJ. A pluviometria da cidade, área de captação e a estimativa do consumo de água não potável foi estimada para a Universidade Candido Mendes e uma residência dimensionada para cinco moradores. O custo de implantação, manutenção e valor da água tratada foi usado para calcular a viabilidade econômica do sistema. A precipitação na década de 2000 é significativamente maior do que na década de 1990. Os quatro primeiros e os dois últimos meses do ano são os mais chuvosos, enquanto que junho a agosto são mais secos. Apesar da água coletada atender a 100% da demanda, o projeto não é economicamente viável na residência. Na universidade, a coleta atenderia a 27% da demanda anual, no entanto, seria economicamente viável. O armazenamento e uso de água pluvial em áreas urbanas colaboram para a preservação do meio ambiente, é uma ferramenta de educação ambiental, evita enchentes, escassez e traz benefícios econômicos devido a redução do consumo de água tratada. Sua implantação em residência poderia ser incentivada com atos governamentais, como a redução de impostos. Para as empresas, além de redução de custos, é um sistema que pode compor o marketing verde, um seguimento de mercado em ascensão.

At the littoral region samples were taken from three monospecific macrophytes stands (Typha domingensis, Eleocharis interstincta and Potamogeton stenostachys. The methane concentration in the pore water at the littoral region was higher than the concentration found at the limnetic region in each fraction of the sediment. The higher methane concentration in the superficial fraction of the sediment (0-2 cm was shown at the P. stenostachys stand (3.7 mM. It was the only significantly different (p0.05. It could be concluded that there was a high influence of aquatic macrophytes on the pore water methane concentration.O objetivo dessa pesquisa foi determinar a concentração de metano na coluna d'água e na água intersticial do sedimento nas regiões limnética e litorânea de uma lagoa costeira (Lagoa Cabiúnas, Macaé, RJ.

In the samples soil chemical and physical analyses were accomplished. Were evaluated the soil aggregate stability; the bulk density (BD and the total volume of pores (TVP, total organic carbon (TOC and soil fertility. To study the multidimensional effect of soil attributes the Principal Component Analysis (PCA was applied. The pastures areas showed a good aggregation levels, in the different times and depths evaluated. The grasses Tifton 85 and Braquiária propitiated a higher TOC contribution in the depth of 0-10 cm and also larger aggregate weight in the class> 2,0mm, in the dry period. Higher values of BD were observed in the TI. In the rainy period it was observed a BD reduction and TVP increase, mainly for the Suázi areas. In a general way, the positions of the hillside TS and TM were the ones that showed the higher values for the physical and chemical attributes indicating a better soil quality in these areas. In the TI area the lowest levels of soil quality were observed, possibly for the accentuated steepness of this last position of the slope in relation to the other positions. The PCA separated the areas in function of seasonal variation. The dry season presented the higher correlation values with soil quality attributes such as the aggregation indexes and TOC. The aggregate weight distribution in function of the size classes, especially > 2,0 mm, MGD, MWD and TOC were a indicative

MÉTODOS: Estudo transversal com 418 alunas do ensino médio de três escolas de diferentes perfis, localizadas na cidade do Rio de Janeiro, RJ, em 2010. Aplicou-se questionário estruturado, abordando características sociodemográficas, comportamento sexual e avaliação da consulta ginecológica. Utilizou-se o teste de Qui-quadrado (Yates e o t de Student, adotando-se p < 0,05. RESULTADOS: Alunas dos colégios privado e público apresentaram perfis semelhantes e diferiram daquelas da rede pública estadual que tiveram nível socioeconômico mais baixo, menor escolaridade dos responsáveis, predominância da raça negra, maior número de parceiros, gestações e histórico de violência sexual. As médias de idades da menarca e sexarca foram semelhantes entre as estudantes e a primeira consulta ginecológica foi significativamente mais tardia nas alunas da rede estadual. A maioria referiu conhecimento sobre anticoncepção e doenças sexualmente transmissíveis, porém pequena parte obteve essas orientações na consulta. As estudantes manifestaram desejo de que o profissional investisse mais tempo, paciência e disponibilidade no atendimento. CONCLUSÕES: O atendimento ginecológico na adolescência é insatisfatório segundo a avaliação das adolescentes estudadas. As usuárias dos serviços privados submetem-se à consulta ginecológica em idade mais precoce do que aquelas que têm acesso apenas à rede pública. É necessário criar mecanismos que facilitem o acesso e a adesão desse grupo etário à rotina preventiva ginecológica.

    Full Text Available A prática de utilizar elementos da natureza com finalidade de auxiliar o homem já é bastante antiga. Desde os tempos primitivos, plantas, animais e elementos químicos fazem parte dos “medicamentos” que o homem utiliza. Com o passar do tempo, baseado no conhecimento do homem, surgiram pesquisas a fim de verificar o potencial de certas plantas, a partir daí surgiram os fármacos compostos de matéria prima vegetal, pois surgiram do isolamento de alguns extratos vegetais. O objetivo deste trabalho é fazer um levantamento de dados a fim de obtermos informações sobre a prescrição de tratamentos à base de plantas medicinais e fitoterápicos por médicos do SUS (Sistema Único de Saúde, do município de Teresópolis, RJ. Foram entrevistados 18 médicos de diferentes especialidades, do ambulatório do UNIFESO. Do total de entrevistados, 83,3%, afirmou acreditar no potencial dos medicamentos à base de plantas medicinais e apoia o uso destes medicamentos, mas a maioria, 94,4%, diz não conhecer o programa, que é exatamente o que regulamenta o uso de plantas medicinais, e possui um “banco de dados” das plantas que tem sua “confiabilidade” verificada. O fato de a maioria dos médicos não terem conhecimento sobre o programa nacional de plantas medicinais, é algo preocupante, pois foi possível perceber na realização desta pesquisa, que alguns consideram o uso de plantas, ou de medicamentos à base de plantas medicinais uma forma de tratamento com menos efeitos colaterais, porém esta falta de informação sobre o programa não garante uma relação risco-benefício favorável. Assim, é de total importância que médicos formados e acadêmicos conheçam o programa nacional de plantas medicinais para uma possível implantação de programas que incentivem o de tratamentos à base de plantas medicinais pelo SUS como uma alternativa mais viável.

Este trabalho teve como objetivo conhecer a época de floração e frutificação de 21 espécies arbóreas nativas em área fragmentada de Mata Atlântica em Itaboraí, RJ. Foram acompanhadas mensalmente 91 matrizes, no período de janeiro a dezembro de 2011. A maior parte das espécies floresceu no final da estação seca e início da chuvosa, tendo sido observada correlação moderada e negativa entre floração e fotoperíodo. Observaram-se dois picos de frutificação: de março a abril para as espécies zoocóricas, e de setembro a outubro para espécies não zoocóricas, com correlação positiva entre precipitação e frutificação de espécies zoocóricas. Foi alta a incidência de patógenos nos frutos, comprometendo a produção de sementes de Machaerium hirtum, Melanoxylon brauna, Machaerium brasiliense e Psidium guineense. Outras espécies apresentaram baixa produção de frutos, como Andira sp., Swartzia oblata, Guarea guidonea e Enterolobium glaziovii. A sincronia de floração e frutificação entre as matrizes foi baixa para a maioria das espécies. A falta de trabalhos de fenologia para a maioria das espécies estudadas (52% reforça a necessidade de pesquisa para a região de estudo.

Os alunos das escolas privadas obtiveram as melhores notas (75% de acertos e um avanço significativo de conhecimento em EA entre a 1ª e a 3ª série. O mesmo não ocorre nas escolas públicas, demonstrando uma estagnação de conhecimento nesta área ao longo do ensino médio. Os alunos das escolas estaduais acertaram, em média, 73% das questões, enquanto que na rede federal de ensino estes acertaram 67%. O avanço no conhecimento ambiental ao longo da permanência do discente no ensino médio deveria ser melhorado nas escolas, principalmente nas públicas, considerando o aspecto genérico das perguntas do questionário. O fato preocupante foi observar que nas escolas públicas não há avanço de conhecimento nesta área entre a 1ª e a 3ª série. Portanto, é necessária uma abordagem mais efetiva nas práticas desenvolvidas no ambiente escolar relativas as questões ambientais.

    Full Text Available Variations of nanoplankton (2-20 µm and filamentous bacteria (diameter: 0.5-2.0 µm of Guanabara Bay (RJ, Brazil are presented, considering cell density and carbon content of auto- and heterotrophs. Our goal is to contribute to future modeling of local trophic dynamics. Subsurface water samples were taken weekly during the year 2000 at two sites: Urca (close to the entrance, more saline, eutrophic and Ramos (inner area, less saline, hypertrophic. Microscopic analysis was done by epifluorescence and cell density was converted to biomass through cell biovolume. Total nanoplankton was about 10(8 cells.l-1 in most samples (>57%, and total filamentous bacteria densities varied from 10(5 to 10(8 fil.l-1. Autotroph density was one order of magnitude higher at Ramos, both for nanoplankton (Md: 10(8cells.l-1 at Ramos and 10(7cells.l-1 at Urca and for filamentous bacteria (Md: 10(6 fil.l-1 at Ramos and 10(5 fil.l-1 at Urca. The same was observed for autotrophic biomass (Md: 10³µgC.l-1 at Ramos and 10¹µgC.l-1 at Urca for nanoplankton; Md: 28µgC.l-1 at Ramos and 1.4µgC.l-1 at Urca for filamentous bacteria. The relative contribution of autotrophs increased after conversion to biomass. Seasonal variation was conspicuous for filamentous bacteria at both sites and for nanoplankton only at Ramos, with maximum autotrophic abundances during the rainy period (spring-summer.Variações do nanoplâncton (2-20µm e bactérias filamentosas (diâmetro: 0.5-2.0 µm da Baía de Guanabara (RJ, Brasil são apresentadas, considerando densidade celular e biomassa de autótrofos e heterótrofos.

    Full Text Available Cancer is the second leading cause of death in the US and in Mississippi. Breast cancer (BC is the most common cancer among women, and the underlying pathophysiology remains unknown, especially among African American (AA women. The study purpose was to examine the joint effect of menopause status (MS and hormone replacement therapy (HRT on the association with cancers, particularly BC using data from the Jackson Heart Study. The analytic sample consisted of 3202 women between 35 and 84 years of which 73.7% and 22.6% were postmenopausal and on HRT, respectively. There were a total of 190 prevalent cancer cases (5.9% in the sample with 22.6% breast cancer cases. Menopause (p < 0.0001, but not HRT (p = 0.6402, was independently associated with cancer. Similar results were obtained for BC. BC, cancer, hypertension, type 2 diabetes, prevalent cardiovascular disease, physical activity and certain dietary practices were all significantly associated with the joint effect of menopause and HRT in the unadjusted analyses. The family history of cancer was the only covariate that was significantly associated with cancer in the age-adjusted models. In examining the association of cancer and the joint effect of menopause and HRT, AA women who were menopausal and were not on HRT had a 1.97 (95% CI: 1.15, 3.38 times odds of having cancer compared to pre-menopausal women after adjusting for age; which was attenuated after further adjusting for family history of cancer. Given that the cancer and BC cases were small and key significant associations were attenuated after adjusting for the above mentioned covariates, these findings warrant further investigation in studies with larger sample sizes of cancer (and BC cases.

    Resistance to angiotensin II (Ang II)-induced hypertension in T-cell-deficient male mice with a targeted mutation in the recombination-activating gene-1 ( Rag1 ) on the C57BL/6J background (B6. Rag1 -/- -M), which was reported by 5 independent laboratories including ours before 2015, has been lost. In mice purchased from Jackson Laboratory in 2015 and 2016, the time course and magnitude increase in mean arterial pressure induced by 2 weeks of Ang II infusion at 490 ng/kg per minute was identical between B6. Rag1 -/- -M and male wild-type littermates. Moreover, there were no differences in the time course or magnitude increase in mean arterial pressure at the lowest dose of Ang II (200 ng/kg per minute) that increased mean arterial pressure. This loss in Ang II resistance is independent of T cells. Angiotensin type 1-receptor binding was 1.4-fold higher in glomeruli isolated from recently purchased B6. Rag1 -/- -M suggesting an increase in renal angiotensin type 1-receptor activity masks the blood pressure protection afforded by the lack of T cells. The phenotypic change in B6. Rag1 -/- -M has implications for investigators using this strain to study mechanisms of T-cell modulation of Ang II-dependent blood pressure control. These findings also serve as a reminder that the universal drive for genetic variation occurs in all animals including inbred mouse strains and that spontaneous mutations leading to phenotypic change can compromise experimental reproducibility over time and place. Finally, these observations illustrate the importance of including experimental details about the location and time period over which animals are bred in publications involving animal studies to promote rigor and reproducibility in the scientific literature. © 2017 American Heart Association, Inc.

    Fatty acid profile analysis is a tool for dietary investigation that may complement traditional stomach contents analysis. While recent studies have shown that the liver of sharks fed different diets have differing fatty acid profiles, the degree to which diet is reflected in shark blood serum and muscle tissue is still poorly understood. An 18-week controlled feeding experiment was undertaken using captive Port Jackson sharks (Heterodontus portusjacksoni). Sharks were fed exclusive diets of artificial pellets treated with fish or poultry oil and sampled every 6 weeks. The fatty acid profiles from liver, blood serum, and muscle were affected differently, with the period from which significant differences were observed varying by tissue and diet type. The total fatty acid profiles of fish oil and poultry oil fed sharks were significantly different from week 12 onwards in the liver and blood serum, but significant differences were only observed by week 18 in the muscle tissue of sharks fed different diets. The drivers of dissimilarity which aligned with dietary input were 14:0, 18:2n-6, 20:5n-3, 18:1n-9 and 22:6n-3 in the liver and blood serum. Dietary fatty acids accumulated more consistently in the liver than in the blood plasma or muscle, likely due to its role as the central organ for fat processing and storage. Blood serum and muscle fatty acid profiles were influenced by diet, but fluctuated over-time. The low level of correlation between diet and muscle FA profiles is likely a result of low levels of fat (shark muscle tissues. Our findings describe inter-tissue differences in the incorporation of fatty acids from the diet to consumer, which should be taken into account when interpreting dietary patterns from fatty acid profiles.

    When a radiological or nuclear accident that leads to the release of radioactive material to the environment occurs, it is important to implement protective and remediation measures in order to reduce human exposure to radionuclides. Therefore, it is necessary that the procedures to be chosen by the affected country authorities are the most efficient ones, which can only be defined based on previously established criteria. In Brazil, since the radiological accident in Goiania, in 1987, the development of tools to support decision-making in emergencies of this nature was started. The main objective of this work was to establish an acting basis for contaminated areas, in order to protect the individuals of public in case of any accident related to Almirante Alvaro Alberto nuclear power plant, in the municipality of Angra dos Reis (RJ), which leads to contamination to the environment and the consequent exposure of local population or from more distant regions to ionizing radiation. Initially, the high-risk areas near the location of the nuclear power plant were defined. Typical urban environments found in the main cities of these municipalities were surveyed, including homes, streets and recreation areas. The main characteristics of the study area were evaluated using images from Google Earth® and web pages of the municipalities. After the types of areas to be simulated were selected, these were quantified in terms of the number of residents, the size of the streets, and the number of trees, among others, per unit area. Considering the different housing characteristics for the selected municipalities, six main standard scenarios were developed for urban areas, including homes with different shielding, buildings and parks. The simulation of the procedures for each scenario was made with SIEM model, developed by the Institute of Radiation Protection and Dosimetry (IRD/CNEN), formed by the integration of various models including CORAL, focusing on agricultural areas

    Full Text Available Neste artigo, debatemos a urbanização brasileira no século XXI e a heterogeneidade da periferia metropolitana fluminense. Utilizando o exemplo da cidade de São Gonçalo (RJ, listamos referências bibliográficas e apontamos elementos que chamam atenção para a necessidade de entender o papel das cidades periféricas que, apesar da primazia metropolitana, apresentam maior integração com a região metropolitana, compondo uma parte do que alguns autores convencionaram como “periferia integrada”. Como periferia integrada, vemos que os indicadores de mobilidade pendular, o aumento das centralidades, a modernização do território e o índice de desenvolvimento nos obrigam a flexionar alguns consensos sobre essa cidade periférica lida ainda, como cidade-dormitório.

    The study aimed to assess for an association between the degree of severity of the metabolic syndrome and risk of type 2 diabetes beyond that conferred by the individual components of the metabolic syndrome. We assessed HRs for an Adult Treatment Panel III (ATP-III) metabolic syndrome score (ATP-III MetS) and a sex- and race-specific continuous metabolic syndrome severity z score related to incident diabetes over a median of 7.8 years of follow-up among participants of two observational cohorts, the Atherosclerosis Risk in Communities study (n = 10,957) and the Jackson Heart Study (n = 2137). The ATP-III MetS had an HR for incident diabetes of 4.36 (95% CI 3.83, 4.97), which was attenuated in models that included the individual metabolic syndrome components. By contrast, participants in the fourth quartile of metabolic syndrome severity (compared with the first quartile) had an HR of 17.4 (95% CI 12.6, 24.1) for future diabetes; in models that also included the individual metabolic syndrome components, this remained significant, with an HR of 3.69 (95% CI 2.42, 5.64). There was a race × metabolic syndrome interaction in these models such that HR was greater for black participants (5.30) than white participants (2.24). When the change in metabolic syndrome severity score was included in the hazard models, this conferred a further association, with changes in metabolic syndrome severity score of ≥0.5 having a HR of 2.66 compared with changes in metabolic syndrome severity score of ≤0. Use of a continuous sex- and race-specific metabolic syndrome severity z score provided an additional prediction of risk of diabetes beyond that of the individual metabolic syndrome components, suggesting an added risk conferred by the processes underlying the metabolic syndrome. Increases in this score over time were associated with further risk, supporting the potential clinical utility of following metabolic syndrome severity over time.

T. foetus não foi identificado nas amostras investigadas. A alta freqüência de C. fetus observada nos animais investigados sugere a presença da campilobacteriose na região do Médio Paraíba, em rebanhos com problemas reprodutivos.Thirty nine breeding bulls from dairy farms (n=9 and beef farms (n=30 located in Médio Paraíba region at Rio de Janeiro - Brazil state were investigated for the presence of Campylobacter fetus and Tritrichomonas foetus. For Campylobacter investigation, smegma samples were examined by culture and prepucial washings were examined by direct immunofluorescence technique (DIF. The prepucial washings were also examined for Tritrichomonas foetus presence by direct examination. C. fetus was identified in 14 samples (35.9 % by DIF technique and C. fetus subspecies venerealis was isolated from four samples (10.3%. T. foetus was not detected in bull samples. The high frequency of C. fetus observed in bull samples suggests the occurrence of Campylobacteriosis among herds which have reproductive problems at the Médio Paraíba region.

Após denúncia na mídia, em 1989, a FEEMA detectou que, com a desativação da fábrica, foram deixados resíduos da produção dos pesticidas, causando a contaminação do solo. Neste trabalho foram realizadas análises foliares e de solo em dois talhões de espécies de eucalipto (Eucalyptus grandis e Corymbia citriodora (Hook. K.D. Hill & L.A.S. Jhonson, com o objetivo de avaliar o potencial da espécie como fitorremediador de área contaminada por organoclorados. Coletaram-se cinco amostras compostas de folhas (três do C. citriodora e duas do E. grandis e uma composta de solo em cada um dos talhões estudados para análise de organoclorados por cromatografia gasosa. As alturas médias dos talhões de E. grandis e C. citriodora foram, respectivamente, de 9,1 e 16,8 com diâmetros médios de 7,8 e 15,95 cm; a média de C. citriodora foi similar à de outros plantios em regiões de mata atlântica, ficando a de E. grandis pouco abaixo. Detectou-se a presença de organoclorados nas folhas analisadas, porém em baixas concentrações. Nos solos, as concentrações encontradas foram altas, sendo maiores no talhão de E. grandis. Os resultados foram comparados com análises prévias na área, indicando que as espécies atuaram como fitorremediadoras, especialmente o C. citriodora, uma vez que houve redução na contaminação do solo e absorção dos organoclorados pelas folhas.The Malaria National Service built a factory of organoclorine pesticides used in public health campaigns (HCH and DDT between 1950 and 1965, at Cidade dos Meninos, in the municipal district of Duque de Caxias/RJ to control the dissemination of endemic rural diseases.

    2013-09-01

    Full Text Available This study examined the impacts of aircraft emissions during the landing and takeoff cycle on PM2.5 concentrations during the months of June and July 2002 at the Hartsfield–Jackson Atlanta International Airport. Primary and secondary pollutants were modeled using the Advanced Modeling System for Transport, Emissions, Reactions, and Deposition of Atmospheric Matter (AMSTERDAM. AMSTERDAM is a modified version of the Community Multiscale Air Quality (CMAQ model that incorporates a plume-in-grid process to simulate emissions sources of interest at a finer scale than can be achieved using CMAQ's model grid. Three fundamental issues were investigated: the effects of aircraft on PM2.5 concentrations throughout northern Georgia, the differences resulting from use of AMSTERDAM's plume-in-grid process rather than a traditional CMAQ simulation, and the concentrations observed in aircraft plumes at subgrid scales. Comparison of model results with an air quality monitor located in the vicinity of the airport found that normalized mean bias ranges from −77.5% to 6.2% and normalized mean error ranges from 40.4% to 77.5%, varying by species. Aircraft influence average PM2.5 concentrations by up to 0.232 μg m−3 near the airport and by 0.001–0.007 μg m−3 throughout the Atlanta metro area. The plume-in-grid process increases concentrations of secondary PM pollutants by 0.005–0.020 μg m−3 (compared to the traditional grid-based treatment but reduces the concentration of non-reactive primary PM pollutants by up to 0.010 μg m−3, with changes concentrated near the airport. Examination of subgrid-scale results indicates that median aircraft contribution to grid cells is higher than median puff concentration in the airport's grid cell and outside of a 20 km × 20 km square area centered on the airport, while in a 12 km × 12 km square ring centered on the airport, puffs have median concentrations over an order of magnitude higher than aircraft

    This study examined the petrographic and geochemical characteristics of two lignite beds (3500 and 4500 beds, Manning Formation, Jackson Group, Eocene) that are mined at the Gibbons Creek mine in east-central Texas. The purpose of the study was to identify the relations among sample ash yield, coal petrography, and trace-element concentrations in lignite and adjoining rock layers of the Gibbons Creek mine. Particular interest was given to the distribution of 12 environmentally sensitive trace elements (As, Be, Cd, Cr, Co, Hg, Mn, Ni, Pb, Sb, Se, and U) that have been identified as potentially hazardous air pollutants (HAPs) in the United States Clean Air Act Amendments of 1990. Eleven lignite, floor, and rock parting samples were collected from incremental channel samples of the 3500 and 4500 beds that were exposed in a highwall of pit A3 at the Gibbons Creek mine. Short proximate and ultimate and forms of sulfur analyses were performed on all lignite samples, and lignite and rock samples were analyzed for 60 major, minor and trace elements. Representative splits of all lignite samples were ground and cast into pellets, and polished for petrographic analyses in blue-light fluorescence and reflected white light to determine liptinite, inertinite, and huminite maceral group percentages. The following observations summarize our results and conclusions about the geochemistry, petrography, and sedimentology of the 3500 and 4500 beds of the Gibbons Creek lignite deposit: (1) Weighted average dry (db) ash yield for the two beds is 29.7%, average total sulfur content is 2.6%, and average calorific value is 7832 Btu (18.22 MJ/kg). Ash yields are greatest in the lower bench (59.33% db) of the 3500 bed and in the upper bench of the 4500 bed (74.61% db). (2) For lignite samples (on a whole-coal basis), the distributions of two of the HAPs (Pb and Sb) are positively related to ash yield, probably indicating an inorganic affinity for these elements. By using cluster analysis we

    When a radiological or nuclear accident that leads to the release of radioactive material to the environment occurs, it is important to implement protective and remediation measures in order to reduce human exposure to radionuclides. Therefore, it is necessary that the procedures to be chosen by the affected country authorities are the most efficient ones, which can only be defined based on previously established criteria. In Brazil, since the radiological accident in Goiania, in 1987, the development of tools to support decision-making in emergencies of this nature was started. The main objective of this work was to establish an acting basis for contaminated areas, in order to protect the individuals of public in case of any accident related to Almirante Alvaro Alberto nuclear power plant, in the municipality of Angra dos Reis (RJ), which leads to contamination to the environment and the consequent exposure of local population or from more distant regions to ionizing radiation. Initially, the high-risk areas near the location of the nuclear power plant were defined. Typical urban environments found in the main cities of these municipalities were surveyed, including homes, streets and recreation areas. The main characteristics of the study area were evaluated using images from Google Earth® and web pages of the municipalities. After the types of areas to be simulated were selected, these were quantified in terms of the number of residents, the size of the streets, and the number of trees, among others, per unit area. Considering the different housing characteristics for the selected municipalities, six main standard scenarios were developed for urban areas, including homes with different shielding, buildings and parks. The simulation of the procedures for each scenario was made with SIEM model, developed by the Institute of Radiation Protection and Dosimetry (IRD/CNEN), formed by the integration of various models including CORAL, focusing on agricultural areas

Optou-se por uma pesquisa de base interpretativa, na qual se utilizou entrevista semiestruturada e análise de conteúdo em sua vertente temática. Foram incluídas 18 gestantes e oito puérperas (n=26, sendo sete adolescentes e 19 adultas; primíparas e multíparas. Para as mulheres, comer e assistir à televisão, comer fora de casa e comer com parentes e amigos no fim de semana eram formas de associar lazer à comida, aumentando o prazer por ela. A renda foi apontada como a principal barreira para o consumo de alimentos saudáveis, que era prioridade das crianças. Por esses motivos, leite, verduras, legumes e frutas eram pouco consumidos. A dieta era composta basicamente por arroz, feijão e frango. Houve preferência por "besteiras". As mulheres estavam submetidas a uma alimentação monótona. Ressalta-se a importância da compreensão e valorização das questões socioculturais e econômicas que influenciam as práticas alimentares, a fim de que a orientação alimentar e nutricional, visando à alimentação saudável, possa ser negociada e ajustada às necessidades e à subjetividade das mulheres grávidas.This study aimed to analyze the self-reported eating practices of pregnant and postpartum women living in a group of slum communities in the city of Rio de Janeiro, RJ, Brazil.

    Abstract. This study evaluated the pupa-productivity of the entomologic surveillance according methodology used by the official Program for Dengue Control in Brazil (PDCB for Aedes aegypti (Linnaeus and Aedes albopictus (Skuse in Parati, RJ, Brazil. The highest number of A. aegypti pupae were found in drains (31%, bottles and cans (23%; and the highest number of A. albopictus pupae were found in bottles and cans (24%, and plant vases (21%. Of the total pupae identified 84.3% and 79.3% of A. aegypti and A. albopictus respectively were collected in small receptacles: bottles, plants vase, tires, bromeliads and tree holes. These productivities are not supported by literature and can be explained by the restrictions of access for the bigger receptacles and lack of training of the agents. The study points out the importance which the small receptacles can have on vector densities in urban environment despite of their productivity and conclude that the entomology surveillance methodology for dengue used in PDCB has no efficacy to identify the bigger and more productive receptacles. This conclusion suggests that this inefficacy can be an important factor for the failures on dengue vector control in Brazil.

Os projetos de pavimento flexível são geralmente feitos para uma vida útil de 5 anos, assim após esse prazo são necessárias intervenções para restauração. Em Belford-Roxo, RJ, a pavimentação da maior parte da cidade não atende as condições básicas que a população necessita. Buscou-se particularizar tal problema, segundo a ótica e os processos de avaliação contidos no Manual de Restauração de Pavimentos Asfálticos do Departamento Nacional de Infraestrutura de Transportes utilizando o método da avaliação objetiva de superfície pela determinação do Índice de Gravidade Global. A aplicação adaptada para vias locais mostrou-se efetiva, pois relata de forma simplificada a condição funcional do pavimento. Uma vez que pouco se usam essas técnicas, essa aplicação se faz pertinente para um adequado projeto de restauração evitando aplicação de recursos desnecessários.

The stepwise technique was used for the selection of the explanatory variable. Measurements of PM10 concentration were made between 05/01/2002 and 08/31/2003 in the city of Rio de Janeiro, RJ, Brazil. The regression coefficient (r² for the models fitting was satisfactory, with better results for model M2 (r² = 0.557 compared to model M1 (r² = 0.334. The weather variables presented negative correlation with PM10, with the exception of the wind direction index, which, similarly to PM10, i-1, had positive correlation. The air relative humidity and the rainfall were the most significant weather variables in the models. However, PM10, i-1 was the most significant variable, when included in the model. The air temperature was statistically not significant (p > 0.05 for both models. M2 model showed an agreement between the estimated and observed values and a better precision than M1 model. In terms of air quality forecast, both models presented satisfactory results, but model M2 was superior.

Os escleródios recuperados dos substratos tratados nos coletores solares foram plaqueados em meio de cultura e submetidos à coloração em solução de cloreto de trifenil-tetrazólio (TCT. A coloração em TCT foi utilizada para comprovar se os escleródios não-germinados em meio de cultura foram realmente inativados pelo calor ou se houve indução de fungistase. No primeiro ensaio, em dia nublado, o máximo de temperatura alcançado no substrato foi de 45ºC e a germinação dos escleródios foi nula e acompanhada de 100% de colonização por bactérias. Nas duas últimas datas de avaliação, em dias ensolarados, as temperaturas máximas alcançadas nos substratos variaram de 60 a 80ºC e os escleródios foram totalmente erradicados, em apenas um dia de tratamento. Nos três ensaios, os escleródios tratados não apresentaram atividade de desidrogenase, evidenciada pela falta de coloração avermelhada interna na presença de TCT, corroborando a inativação pelo calor. Conclui-se que mesmo em condições sub-ótimas para tratamento de substratos em coletores solares, a exposição prolongada a temperaturas elevadas foi suficientemente danosa aos escleródios do patógeno, tornando-os mais vulneráveis ao antagonismo microbiano. Os coletores solares foram eficientes na desinfestação dos substratos, visando o controle de S. rolfsii, nas condições avaliadas.Although there is a

    Full Text Available Os problemas de inundações no município de São Gonçalo (RJ são cada vez mais comuns. Esta realidade é favorecida pelas condições geográficas do município somadas à intensa ocupação urbana. O agravamento das inundações também pode estar relacionado ao nível de percepção e compreensão da população em relação ao funcionamento de rios e bacias hidrográficas. O desconhecimento da dinâmica ambiental atinge também as escolas, onde o conceito de bacia hidrográfica não está sendo devidamente repassado e discutido dentro de ações de Educação Ambiental. Diante deste quadro, o presente trabalho se propôs a investigar a percepção ambiental em relação aos rios e bacias hidrográficas urbanizadas, de alunos do Ensino Básico de escolas públicas situadas em duas bacias hidrográficas que apresentam intensa degradação e descaracterização de seus rios. Para tanto, 80 estudantes foram entrevistados, percebendo-se que os mesmos não possuem conhecimento sistematizado acerca das bacias hidrográficas, o que contribui para o pouco compromisso com a preservação ambiental. A execução dessa proposta de pesquisa permitiu uma reflexão sobre as formas de abordagem do conteúdo escolar sobre rios e bacias hidrográficas.

    Full Text Available OBJETIVO: verificar a prevalência de obesidade entre adultos das 86 famílias agricultoras de um bairro de Petrópolis, RJ, e analisar seus determinantes socioculturais. MÉTODOS: estudo quantitativo e qualitativo sobre nutrição, práticas alimentares e de trabalho realizado em 2008. Dados antropométricos foram coletados por inquérito nutricional domiciliar e o material qualitativo por observação participante e entrevistas. RESULTADOS: a prevalência de obesidade foi baixa (9,3% entre os homens, mas bastante elevada entre as mulheres (29,9%. A prática agrícola local implica em atividade física leve para mulheres e intensa para homens. Essa diferença não é acompanhada na dieta, semelhante para homens e mulheres, com predomínio de alimentos de alto valor calórico. A produção familiar objetiva essencialmente a venda. A agricultura mercantil e a decorrente especialização dos cultivos favorecem comprar alimentos no mercado em vez de produzir para autoconsumo. CONCLUSÃO: os aspectos socioculturais e ocupacionais estudados podem ter contribuído para elevar a prevalência de obesidade nas mulheres e podem ser úteis no estudo de outros grupos com características semelhantes. Esta pesquisa ratifica a importância de estudar a obesidade em nível local, integrando abordagens quantitativas e qualitativas para identificar possíveis limitações e portas de entrada para ações de intervenção localmente relevantes.

    Full Text Available Tears are secreted from the lacrimal gland (LG, a dysfunction in which induces dry eye, resulting in ocular discomfort and visual impairment. Honey bee products are used as a nutritional source in daily life and medicine; however, little is known about their effects on dry eye. The aim of the present study was to investigate the effects of honey bee products on tear secretion capacity in dry eye. We selected raw honey, propolis, royal jelly (RJ, pollen, or larva from commercially available honey bee products. Tear secretion capacity was evaluated following the oral administration of each honey bee product in a rat blink-suppressed dry eye model. Changes in tear secretion, LG ATP content, and LG mitochondrial levels were measured. RJ restored the tear secretion capacity and decrease in LG ATP content and mitochondrial levels to the largest extent. Royal jelly can be used as a preventative intervention for dry eye by managing tear secretion capacity in the LG.

A utilização da análise de imagem orientada a objeto e da mineração de dados no mapeamento geomorfológico permitiu a classificação do relevo em diversas classes e em diferentes níveis taxonômicos, de forma ágil e simplificada, ficando evidente que dois fatores influenciaram fortemente os resultados: (i a segmentação multirresolução associada à possibilidade de se manipular a contribuição de cada variável, pois permitiu a elaboração de estratégias de segmentação mais adequadas aos dados utilizados e às classes geomorfológicas mapeadas; e (ii a seleção do conjunto amostral, pois tal tarefa possui uma relação direta na capacidade do minerador de dados definir parâmetros mais eficazes para a classificação do relevo. Vale ressaltar que a classificação geomorfológica por meio da análise de imagem orientada a objeto se destaca dos métodos convencionais devido a sua capacidade de classificação em diferentes níveis e sua rede hierárquica semântica, onde cada classe pode ser dividida em subclasses, adequando-se bem ao mapeamento geomorfológico taxonômico proposto. Por fim, destaca-se que, apesar do grande avanço no mapeamento por meio da OBIA e da mineração de dados, o conhecimento do intérprete sobre o conteúdo a ser mapeado continua a ser imprescindível para os procedimentos de classificação adotados.

    2012-01-01

    Image segmentation is one of the first important parts of image analysis and understanding. Evaluation of image segmentation, however, is a very difficult task, mainly because it requires human intervention and interpretation. In this work, we propose a blind reference evaluation scheme based on regional local–global (RLG) graphs, which aims at measuring the amount and distribution of detail in images produced by segmentation algorithms. The main idea derives from the field of image understanding, where image segmentation is often used as a tool for scene interpretation and object recognition. Evaluation here derives from summarization of the structural information content and not from the assessment of performance after comparisons with a golden standard. Results show measurements for segmented images acquired from three segmentation algorithms, applied on different types of images (human faces/bodies, natural environments and structures (buildings)).

    To review the clinical and polysomnographic features of the sleep disorder occurring in the recently described anti-IgLON5 disease. The hallmark of the disease is the presence of antibodies against IgLON5, a neural cell adhesion molecule of unknown function. The disease presents a robust HLA association, and the neuropathological examination shows a novel neuronal tauopathy with predominant hypothalamic and brainstem involvement. Most patients (> 80%) present sleep-related vocalizations with movements and behaviors and sleep-disordered breathing. Polysomnographic studies show (1) a complex NREM sleep parasomnia at sleep initiation characterized by undifferentiated NREM or poorly structured N2 sleep with sleep-talking or mumbling, and simple or finalistic movements followed by normal periods of N3 or N2 NREM sleep, (2) REM sleep behavior disorder (RBD), and (3) obstructive sleep apnea with stridor. The last two features appear mainly in periods where NREM sleep normalizes. Identification of the anti-IgLON5 sleep disorder is important to suspect the disease. The combination of abnormal NREM sleep initiation, followed by normal periods of NREM sleep and RBD, represents a novel parasomnia.

    Full Text Available Existe uma série de alternativas para trabalhar com a dimensionalidade dos elementos de uma paisagem, e mesmo assim o geoprocessamento possui uma limitação estabelecida pela não consideração da irregularidade do espaço a ser analisado. Neste sentido, a análise em superfície modelada apresenta uma acuracidade maior no que tange a mensurações na paisagem, como é o caso de análises geomorfológicas. Com o intuito de fornecer mais um subsídio de como as diferentes observações em superfície planimétrica e modelada podem se comportar mediante as mensurações morfológicas, o presente trabalho busca comparar resultados de índices geomorfológicos obtidos a partir destes dois tipos de observações na bacia do rio Cuiabá, localizada no município de Petrópolis (RJ. Todo estudo foi desenvolvido na escala de 1:10.000, compilada das bases topográficas onde foram construídos os índices geomorfológicos em superfície planimétrica, tais como Gradiente topográfico (Gt, Densidade de drenagem (Dd e Índice de Eficiência de Drenagem (IED. Estes índices foram extraídos para as 41 bacias de segunda ordem que compõem a bacia do Rio Cuiabá. Os índices Dd e IED foram aplicados à superfície modelada a partir de um modelo digital de elevação (MDE, que teve como fonte os dados planialtimétricos da base cartográfica.

    The Tröllaskagi peninsula is located in northern Iceland, between meridians 19°30'W and 18°10'W, jutting out into the North Atlantic to latitude 66°12'N and joining the central highlands to the south. About 150 glaciers located on the Tröllaskagi peninsula reached their Holocene maximum extent during the Little Ice Age (LIA) maximum at the end of the 19th century. The sudden warming at the turn of the 20th century triggered a continuous retreat from the LIA maximum positions, interrupted by a reversal trend during the mid-seventies and eighties in response to a brief period of climate cooling. The aim of this paper is to analyze the relationships between glacial and climatic evolution since the LIA maximum. For this reason, we selected three small debris-free glaciers: Gljúfurárjökull, and western and eastern Tungnahryggsjökull, at the headwalls of Skíðadalur and Kolbeinsdalur, as their absence of debris cover makes them sensitive to climatic fluctuations. To achieve this purpose, we used ArcGIS to map the glacier extent during the LIA maximum and several dates over four georeferenced aerial photos (1946, 1985, 1994 and 2000), as well as a 2005 SPOT satellite image. Then, the Equilibrium-Line Altitude (ELA) was calculated by applying the Accumulation Area Ratio (AAR) and Area Altitude Balance Ratio (AABR) approaches. Climatological data series from the nearby weather stations were used in order to analyze climate development and to estimate precipitation at the ELA with different numerical models. Our results show considerable changes of the three debris-free glaciers and demonstrates their sensitivity to climatic fluctuations. As a result of the abrupt climatic transition of the 20th century, the following warm 25-year period and the warming started in the late eighties, the three glaciers retreated by ca. 990-1330 m from the LIA maximum to 2005, supported by a 40-metre ELA rise and a reduction of their area and volume of 25% and 33% on average

    Studies have suggested that social inequalities in chronic disease outcomes differ between industrialized and developing countries, but few have directly compared these effects. We explored inequalities in hypertension and diabetes prevalence between African-descent populations with different levels of educational attainment in Jamaica and in the United States of America (USA), comparing disparities within each location, and between countries. We analyzed baseline data from the Jackson Heart Study (JHS) in the USA and Spanish Town Cohort (STC) in Jamaica. Participants reported their highest level of educational attainment, which was categorized as 'less than high school' (HS). Educational disparities in the prevalence of hypertension and diabetes were examined using prevalence ratios (PR), controlling for age, sex and body mass index (BMI). Analyses included 7248 participants, 2382 from STC and 4866 from JHS, with mean age of 47 and 54 years, respectively (p hypertension and diabetes was significantly higher in the JHS compared to STC, 62% vs. 25% (p hypertension and diabetes in both studies; however, after accounting for confounding or interaction by age, sex and BMI these effects were attenuated. For hypertension, after adjusting for age and BMI, a significant education disparity was found only for women in JHS, with PR of 1.10 (95% CI 1.04-1.16) for  HS and 1.07 (95% CI 1.01-1.13) for HS vs > HS. For diabetes; when considering age-group and sex specific estimates adjusted for BMI, among men: significant associations were seen only in the 45-59 years age-group in JHS with PR 1.84 (95% CI 1.16-2.91) for  HS. Among women, significant PR comparing  HS was seen for all three age-groups for JHS, but not in STC; PR were 3.95 (95% CI 1.94-8.05), 1.53 (95% CI 1.10-2.11) and 1.32 (95% CI 1.06-1.64) for 25-44, 45-59 and 60-74 age-groups, respectively. In Jamaica, educational disparities were largely explained by age, sex and BMI, while in the USA these

    The Johnson County Blue River Main Wastewater Treatment Facility discharges into the upper Blue River near the border between Johnson County, Kansas and Jackson County, Missouri. During 2005 through 2007 the wastewater treatment facility underwent upgrades to increase capacity and include biological nutrient removal. The effects of wastewater effluent on environmental and biological conditions of the upper Blue River were assessed by comparing an upstream site to two sites located downstream from the wastewater treatment facility. Environmental conditions were evaluated using previously and newly collected discrete and continuous data, and were compared with an assessment of biological community composition and ecosystem function along the upstream-downstream gradient. This evaluation is useful for understanding the potential effects of wastewater effluent on water quality, biological community structure, and ecosystem function. In addition, this information can be used to help achieve National Pollution Discharge Elimination System (NPDES) wastewater effluent permit requirements after additional studies are conducted. The effects of wastewater effluent on the water-quality conditions of the upper Blue River were most evident during below-normal and normal streamflows (about 75 percent of the time), when wastewater effluent contributed more than 20 percent to total streamflow. The largest difference in water-quality conditions between the upstream and downstream sites was in nutrient concentrations. Total and inorganic nutrient concentrations at the downstream sites during below-normal and normal streamflows were 4 to 15 times larger than at the upstream site, even after upgrades to the wastewater treatment facility were completed. However, total nitrogen concentrations decreased in wastewater effluent and at the downstream site following wastewater treatment facility upgrades. Similar decreases in total phosphorus were not observed, likely because the biological

MÉTODOS: Foram georreferenciados 1.212 casos de dengue registrados no Sistema de Informação de Agravos de Notificação entre 1998 e 2006, no município de Niterói, RJ, segundo setores censitários. Os setores foram classificados em áreas homogêneas para a ocorrência da doença: favela, estaleiro e urbano. Os casos foram agrupados em cinco períodos: dois interepidêmicos 1998-2000 e 2003-2005; três epidêmicos 2001, 2002 e 2006 e analisados por meio de operações entre camadas em ambiente sistema de informação geográfica. Para identificação de conglomerados com maior intensidade de casos, utilizou-se o método de kernel. O método de varredura espacial de Kulldorff foi usado para confirmação estatística desses clusters. RESULTADOS: Do total de casos, 57% eram do sexo feminino. As faixas etárias com maior concentração de casos foram de 20-29 anos (20,5% e de 30-39 anos (17,7%. O setor favela morro apresentou somente 11% dos domicílios atendidos por serviço de coleta de lixo, o maior percentual de não alfabetizados (8,7% e de chefes de família com rendimentos menores de 1 salário mínimo (29,5%. Os casos permaneceram nos setores denominados favelas. No primeiro ano epidêmico e nos períodos interepidêmicos o maior número de casos estava situado nos setores favelas morro e favela plana; no segundo e terceiro ano de epidemia, situavam-se no setor favela plana. CONCLUSÕES: A parcela economicamente ativa foi a mais atingida na área de estudo. Os setores censitários mostram heterogeneidade espacial em relação às condições de vida e dentro de alguns setores, há diferenciais na distribuição espacial e temporal do risco de ocorrência da dengue.OBJETIVO: Analizar ocurrencia espacial y temporal del dengue y su asociación con la heterogeneidad de características del ambiente

  5. Coal geology of the Paleocene-Eocene Calvert Bluff Formation (Wilcox Group) and the Eocene Manning Formation (Jackson Group) in east-central Texas; field trip guidebook for the Society for Organic Petrology, Twelfth Annual Meeting, The Woodlands, Texas, August 30, 1995

    The Jackson and Wilcox Groups of eastern Texas (fig. 1) are the major lignite producing intervals in the Gulf Region. Within these groups, the major lignite-producing formations are the Paleocene-Eocene Calvert Bluff Formation (Wilcox) and the Eocene Manning Formation (Jackson). According to the Keystone Coal Industry Manual (Maclean Hunter Publishing Company, 1994), the Gulf Coast basin produces about 57 million short tons of lignite annually. The state of Texas ranks number 6 in coal production in the United States. Most of the lignite is used for electric power generation in mine-mouth power plant facilities. In recent years, particular interest has been given to lignite quality and the distribution and concentration of about a dozen trace elements that have been identified as potential hazardous air pollutants (HAPs) by the 1990 Clean Air Act Amendments. As pointed out by Oman and Finkelman (1994), Gulf Coast lignite deposits have elevated concentrations of many of the HAPs elements (Be, Cd, Co, Cr, Hg, Mn, Se, U) on a as-received gm/mmBtu basis when compared to other United States coal deposits used for fuel in thermo-electric power plants. Although regulations have not yet been established for acceptable emissions of the HAPs elements during coal burning, considerable research effort has been given to the characterization of these elements in coal feed stocks. The general purpose of the present field trip and of the accompanying collection of papers is to investigate how various aspects of east Texas lignite geology might collectively influence the quality of the lignite fuel. We hope that this collection of papers will help future researchers understand the complex, multifaceted interrelations of coal geology, petrology, palynology and coal quality, and that this introduction to the geology of the lignite deposits of east Texas might serve as a stimulus for new ideas to be applied to other coal basins in the U.S. and abroad.

    Full Text Available Bogs are ecosystems found mainly in lower zones that separates inner and outer sandy terraces, and rivers and streams from valleys. These environments are always flooded or suffer seasonal flooding or can stay dry in a extended dry season. Its shallow waters increase the role of the sediment in the maintenance of such ecosystem. The Brejo do Espinho (22º56’ S and 42º14’W is a coastal body of water located 108 km from Rio de Janeiro city where are observed the development of thick microbial mats (about 2-4 cm in thickness. Aiming the characterization of the microbial mats, was made monthly collections in five collects in stations located in the bog borders. Microbial mats samples were taken using a spatula, deposited into plastics vials and later fixed with 4% formaldeid solution. For identification of the cyanobacterias, fresh and permanent slides were made. Smooth layered microbial mats present in subtidal and intertida regions are composed by thin layers with different colors: green, red and brown, who show also distinct cyanobacterialcomposition. These structures show stratus of cohesive lamina with low lithification. Analysis revealed 27 species of cyanobacterias. Chroococcaceae Nägeli 1849 family was the main family found with 37% of the total frequency followed by Phormidiaceae Anagnostidis & Komárek 1988 family with 18,5%, Synechococcaceae Komárek & Anagnostidis 1995 family with 11,1%, Pseudanabaenaceae Anagnostidis & Komárek 1988 family with 11,1%, Entophysalidaceae Geitler1925 family with 7,4%, Schizothricaceae Elenkin 1934 family with 7,4% and Oscillatoriaceae Gomont 1892 family with 7,4%. The domain of cyanobacterias in the Brejo do Espinho reflects its general plasticity that allows them to adapt to hostile conditions of the environment.

    Full Text Available With the rising and intensification of production’s activities, as industries, the deforestation taxes show to be on an alarming level. It is wide spread known the consequences that deforestation might cause in metropolitan areas. In order to evalue the consequences of this growing phenomenon, is possible to use a role of ambiental impacts evaluations techniques. One of them is the Preliminary Analysis of Danger (PAD, which is based on qualitative and statistics analysis and might be used in association with other ambiental impacts evaluations techniques. It’s goal is to analyze dangers in potential, it’s causes and consequences, in which is also done an associated risk analysis, which the last is the association between the classifications of frequency and severity, and, in the end, it gives suggestions of measures to avoid these dangers (undesired events. In this study, six dangers have been identified, in which none of them present despicable or low risk (0%, 16% present medium or high risk and 66% present critic risk. These datas point out that the deforestation situation might cause dangers with great consequences to Petropolis’ metropolitan area, just as floodings and earth slidings, which higthlights the urgency of management of the area. DOI: http://dx.doi.org/10.12957/sustinere.2015.20003

    Full Text Available O campo da Comunicação e Saúde no Brasil vem se desenvolvendo e se fortalecendo a cada Conferência Nacional de Saúde (CNS. No relatório final da XII CNS, em 2003, torna-se claro o reconhecimento das rádios comunitárias como instrumento de divulgação e produção de temas relacionados ao SUS. O objetivo foi analisar as relações que se estabelecem entre profissionais de saúde, ouvintes/usuários e comunicadores envolvidos com uma rádio comunitária, de modo a entender como são constituídos os nexos entre um programa de rádio sobre saúde e os imaginários desses sujeitos. Para tal, uma abordagem metodológica qualitativa, fazendo-se uso da etnografia e do estudo de recepção. O campo se constituiu de um programa sobre saúde, o Bloco Mulher Saúde, transmitido pela rádio comunitária Rádio Comunidade FM 104,9 no município de Nova Friburgo, RJ. As discussões foram divididas em categorias analíticas. A comunicação comunitária pode contribuir como mediador político-cultural ampliando as possibilidades de expressão das demandas sobre saúde; existe a manutenção e reprodução do linguajar técnico hegemônico em saúde pelos médicos ao participarem de uma rádio comunitária; a comunicação comunitária pode auxiliar na construção de estratégias para ampliar o controle social no SUS.The field of Communication and Health in Brazil has been developing and getting stronger after each National Health Conference (NHC.

    Full Text Available A falta da prática de cultivo comercial de macroalgas no Brasil junto com a crescente demanda do mercado nacional de ficocolóides é suprida pela importação de algas e colheita em bancos naturais, principalmente na costa nordestina. Na busca de um cultivo em pequena escala para uso das comunidades litorâneas foi implantado um cultivo experimental com H. musciformis, na Ilha da Marambaia, RJ (43º59'35" W e 23º04'00" S. Ao todo foram testadas nove técnicas de fixação da alga nas unidades experimentais de maricultura (UEM. Nos experimentos realizados entre a primavera de 2003 e o outono de 2004, as taxas de crescimento geralmente foram negativas. Entre os invernos de 2004 e 2005, foram na maioria positivas. O fitobentos próximo à UEM foi analisado para verificar o crescimento dessa espécie na assembléia e no cultivo. Observou-se maior percentual de anfípodas e de matéria orgânica nas UEM e a presença de carposporófitos em épocas de baixa salinidade em ambos os locais. Atribuiu-se o baixo rendimento da taxa de crescimento aos fatores ambientais como: ressacas, aderência de matéria orgânica nas algas, herbivoria e danos as UEM por ação antrópica. Constatou-se que o tratamento fixando a muda com abraçadeira foi o de mais fácil manuseio e baixo custo e que somente com a conscientização da comunidade litorânea e remuneração salarial para esta atividade será possível exercer o cultivo de H. musciformis com sucesso.Lack of practice in commercial cultivation of macroalgae in Brazil allied with an increased demand for phycocolloids in the national market is met by importing algae and cropping from natural beds, especially on the Northeastern coast.

Abordamos prioritariamente o intervalo que abrange os últimos 10 anos, período em que acompanhamos de forma sistemática o referido campo empírico. O referencial teórico-metodológico utilizado no curso da pesquisa, na qual se insere esta contribuição, inspira-se com maior ênfase no instrumental da Ergonomia da Atividade e da Psicodinâmica do Trabalho numa perspectiva ergológica. Em nossa análise, além da tendência à precarização do trabalho em sentido mais global, merecem destaque as possíveis perdas no ativo de conhecimento formal e informal (um patrimônio longamente acumulado devido à fragmentação dos coletivos de trabalho, já que consideramos a coesão destes um elemento crucial para a confiabilidade do sistema. Em verdade, a precarização do trabalho contribui para esta fragmentação, e tem como uma de suas causas o avanço pouco criterioso da terceirização, na esteira das várias iniciativas de flexibilização organizacional ligadas à reestruturação produtiva do setor. Isto acarretou conseqüências nefastas para a saúde e a segurança dos trabalhadores indicando que a opção pela terceirização como instrumento de gestão, da forma com que vinha sendo conduzida até recentemente, não estaria considerando tais implicações com o devido rigor.This paper analyses the correlations between the intensive use of outsourcing and labor organizations on offshore oil platforms in the Campos Basin (Rio de Janeiro.

    Full Text Available Este artigo apresenta o estudo das contradições surgidas no Conselho Gestor da Unidade Básica de Saúde da Família de Vargem Grande, Município de Teresópolis-RJ, na resolução das demandas da comunidade. O estudo justifica-se pela necessidade de se entender a micropolítica do controle público de um conselho gestor de uma unidade de Saúde da Família, cuja estratégia é a mudança do modelo de assistência a partir da Rede Básica de Saúde. Objetiva analisar a atuação desse Conselho na resolução dos impasses e problemas daquela comunidade e discutir as contradições surgidas no processo de tomada de decisões. Optou-se por um estudo de caso com abordagem qualitativa. Os sujeitos da pesquisa foram os conselheiros do CG. A coleta de dados foi realizada através da análise das atas do CG e das entrevistas realizadas com conselheiros. Utilizou-se da análise temática para identificar os impasses, problemas e contradições do CG. As análises dos dados apontam que os impasses e problemas são de ordem política, econômica, social e cultural que transcendem a resolução pelo CG. Percebe-se que as atribuições previstas para o CG revelam uma prática de controle restrita à racionalização do serviço através do gerenciamento administrativo da unidade. O CG não conseguiu interferir na política de saúde e na destinação da verba pública. Portanto, os conselheiros exercem atribuições que estão desprovidas de sentido político em garantir o pleno exercício de cidadania e a conquista dos direitos sociais. Conclui-se que o Conselho Gestor de Vargem Grande não representa ainda uma possibilidade efetiva de participação popular no controle público de um Estado ampliado no sentido gramsciano.This paper presents a study on the contradictions of the Manager Council of Vargem Grande Family Health Unit, in Teresópolis City, state of Rio de Janeiro, concerning community health needs.

    To describe the cause and consequence of tear dysfunction-related corneal disease. Perspective on effects of tear dysfunction on the cornea. Evidence is presented on the effects of tear dysfunction on corneal morphology, function, and health, as well as efficacy of therapies for tear dysfunction-related corneal disease. Tear dysfunction is a prevalent eye disease and the most frequent cause for superficial corneal epithelial disease that results in corneal barrier disruption, an irregular optical surface, light scattering, optical aberrations, and exposure and sensitization of pain-sensing nerve endings (nociceptors). Tear dysfunction-related corneal disease causes irritation and visual symptoms such as photophobia and blurred and fluctuating vision that may decrease quality of life. Dysfunction of 1 or more components of the lacrimal functional unit results in changes in tear composition, including elevated osmolarity and increased concentrations of matrix metalloproteinases, inflammatory cytokines, and chemokines. These tear compositional changes promote disruption of tight junctions, alter differentiation, and accelerate death of corneal epithelial cells. Corneal epithelial disease resulting from tear dysfunction causes eye irritation and decreases visual function. Clinical and basic research has improved understanding of the pathogenesis of tear dysfunction-related corneal epithelial disease, as well as treatment outcomes. Copyright © 2011 Elsevier Inc.

MÉTODOS: Estudo de painel com uma amostra aleatória de 118 escolares (seis a 15 anos de idade da rede pública do Rio de Janeiro (RJ, residentes até 2 km do local do estudo. Dados sobre características das crianças foram obtidos por questionário, incluindo o International Study of Asthma and Allergies in Childhood. Exames diários de pico de fluxo foram realizados para medir a função respiratória. Dados diários dos níveis de PM10, SO2, O3, NO2 e CO, temperatura e umidade foram fornecidos por um monitor móvel. As medidas repetidas de função respiratória foram associadas aos níveis dos poluentes por meio de modelo multinível ajustado por tendência temporal, temperatura, umidade do ar, exposição domiciliar ao fumo, ser asmático, altura, sexo, peso e idade das crianças. RESULTADOS: O pico de fluxo expiratório médio foi 243,5 l/m (dp=58,9. A menor média do pico de fluxo expiratório foi 124 l/m e a maior 450 l/m. Para o aumento de 10 µg/m³ de PM10 houve uma diminuição de 0,34 l/min na média do pico de fluxo no terceiro dia. Para o aumento de 10 µg/m³ de NO2 houve uma diminuição entre 0,23 l/min a 0,28 l/min na média do pico de fluxo após a exposição. Os efeitos do CO e do SO2 no pico de fluxo dos escolares não foram estatisticamente significativos. O O3 apresentou um resultado protetor: o aumento de 10 µg/m³ de O3 estaria associado, um dia depois da exposição, a aumento de 0,2 l/min na média da função respiratória.

    {sup 210} Po concentration have been determined in one green alga and in five freshwater plants grown in a pond of the Carapebus restinga (state of Rio de Janeiro). The alga Chara sp showed elevated concentration of {sup 210} Po, similar to that observed in marine algae. All the other plants had the lowest concentration of {sup 210} Po in the stems and the highest in the roots. Intermediate values were observed in the leaves. The unexpected high concentration of {sup 210} Po in the roots, even superior to reported values for roots of plants from high radioactive background areas, must be due to the elevated levels of this radionuclide in associated soils that are known to be rich in humic organic material. There seem to have no translocation of this radionuclide from the roots to the other parts of the plants. (author)

A análise da continuidade de cuidados baseou-se em pesquisa em prontuário, informações da equipe e dos próprios pacientes e/ou familiares seis meses após a absorção ou encaminhamento do paciente. RESULTADOS: Os pacientes admitidos apresentavam diagnóstico de psicose (esquizofrenia, história de internações prévias, funcionamento social pobre e rede de apoio pequena e os pacientes encaminhados apresentavam transtornos ansiosos e depressivos, boa adesão a tratamento ambulatorial, bom funcionamento social e presença de rede social. Quanto à continuidade de cuidados, oito pacientes em 27 tiveram destino desconhecido. Quanto aos encaminhamentos, dos 13 pacientes encaminhados a ambulatórios da rede, sete permaneceram em tratamento, dois retornaram aos CAPS e quatro tiveram destino desconhecido. CONCLUSÕES: Os centros admitem pacientes que se encaixam na definição de um transtorno mental severo e persistente. A continuidade de cuidado foi apontada como problema, provavelmente devido à dificuldade de acompanhar os pacientes na comunidade.OBJETIVO: Analizar los criterios de admisión, encaminamiento y continuidad de cuidado a pacientes utilizados por los equipos de los centros de atención psicosocial. MÉTODOS: Investigación cualitativa con evaluación participativa realizada en tres centros de atenci

    The high environmental impact generated by using of Ordinary Portland Cement (OPC) has lead to the search for alternative materials in the field of civil and building engineering. In addition, there is a tendency to develop cements from industrial by-products, thus reducing pollution and emissions generated by their production. One of the best positioned cements to compete with OPC is Magnesium Phosphate Cement (MPC). The present work studies different dosages of MPC mortars formulated with low-grade MgO by-product (sustainable MPC) incorporating Microencapsulated Phase Change Materials (MPCM) and air entraining additive (AEA) as admixtures (Thermal Sustainable MPC) to improve the thermal behaviour of the material. The aim is developed a new eco-friendly material that leads to reducing energy consumption in buildings. The study is focused on the physical, thermal, and mechanical characterization of TS-MPC mortars to assess their potential use as a thermal prefabricated panel. The results allow to relate the amount of the MPCM and the additive percentage with the thermal and mechanical properties of the TS- MPC. Furthermore, is important to highlight the influence of MPCM not only in the thermal behaviour but also on the increase of the porosity. The experimental results show that the addition of both additives contributes substantially to the improvement of the thermal behaviour of the mortars and converts them on a suitable material to reduce thermal oscillations in buildings.

    Full Text Available To use food-specific IgG antibody detection to explore its application in the allergy dermatoses. 181 patients were included from January 2014 to September 2014. Fourteen food-specific IgG antibodies were detected by ELISA. The positive rates of IgG antibody of the patient group and the healthy group were significantly different. The positive rates of IgG antibody of egg, milk, shrimp and crab took a large proportion in three groups of patients with three kinds of allergy dermatoses of urticaria, eczema and allergic dermatitis, the proportion of which was respectively 70.2%, 77.8% and 71.7%. There was mild and moderate intolerance of food in the allergic dermatitis group while there was no distribution difference of food intolerance in urticaria group and eczema group. Among urticaria and allergic dermatitis patients with positive antibody, the positive rate of children was significantly higher than that of adults while there was no significant difference between children and adults among eczema patients with positive antibody. Allergy dermatoses are closely related to food-specific IgG antibody and the allergy dermatoses patients have a high incidence rate of food intolerance; detecting IgG antibody in patients is of great significance for the diagnosis and treatment of allergy dermatoses.

    2004-01-01

    In 2000, the 11th Circuit Court provided the largest single award in special education history to date, approximately $2.5 million, to two teenaged students who were deaf. The students were judged to have been denied a free, appropriate public education (FAPE), having spent their academic careers in generic special education classes for students with multiple disabilities without the benefit of access to a communication system; the services of a certified, qualified teacher of the deaf; or related services. This article describes the case from the perspective of FAPE, least restrictive environment, and due process in the presence of guardians who did not understand the implications of the Individual Education Program (IEP) teams' decisions; presents a chronology of the case; explores the implications for various stakeholders; and discusses the catastrophic impact on the social, emotional, communication, and academic development and earning potential of the students.

    We report the discovery of a microlensing planet OGLE-2012-BLG-0950Lb with a planet/host mass ratio Periapsis Approx. = 2 x10(exp. -4). A long term distortion detected in both MOA and OGLE light curve can be explained by themicrolens parallax due to the Earths orbital motion around the Sun. Although the finite source effect is not detected, we obtain the lens flux by the high resolution Keck AO observation. Combining the microlens parallax and the lens flux reveal the nature of the lens: a planet with mass of M(sub p) = 35(+17/-)M compared to Earth is orbiting around an M-dwarf with mass of M(sub host) = 0.56(+0.12/-0.16) M compared to the Sun with a planet-host projected separation of r1 = 2.7(+0.6/-0.7) au located at Luminosity Distance = 3.0(+0.8/-1.1) kpc from us. This is the first mass measurement from only microlens parallax and the lens flux without the finite source effect. In the coming space observation-era with Spitzer, K2, Euclid, and WFIRST, we expect many such events for which we will not be able to measure any finite source effect. This work demonstrates an ability of mass measurements in such events.

    Environmental factors and eating habits have had a significant impact on the increased sensitization to allergens in children. This study investigated changes in common allergen sensitivities among children in Taipei City, Taiwan. A total of 142 primary schools in Taipei City, which included 25,094 students aged 7-8 years, were surveyed using an ISAAC questionnaire to screen for allergies. For positive responders, serum allergen-specific IgE was confirmed using the Pharmacia CAP system. A total of 1,500 students (5.98%) had confirmed sensitivities to allergens. Dust mite sensitivity among these children was nearly 90%. The prevalences of sensitivities to Dermatophagoides pteronyssinus, D. farinae and Blomia tropicalis were 90.79%, 88.24%, and 84.63%, respectively. Dog dander (29.95%) was the second most common aeroallergen to induce sensitivity. Allergies to cat dander (8.69%) and to cockroach (15.48%) had decreased dramatically compared with previous analyses. Among the food allergens studied, the most common allergens that induced sensitization were (in order of prevalence) crab, milk, egg white, and shrimp (88.08%, 22.45%, 24.23%, and 21.44%, respectively). Mold and pollen sensitization was identified in fewer than 2% of the schoolchildren. Dust mites remain the most common allergen to induce allergic sensitization among children in Taipei City, while cockroach and mold sensitivities have dramatically declined. Food allergens should also be considered as a trigger of respiratory allergy. Except for dust mites, American cockroach and crab, allergens commonly reported to induce sensitization in other Asian counties are not common in Taiwan.

    Acidity has profound effects on the taste of apples (Malus × domestica). Malic acid is the predominant organic acid in apples. Differences in malic acid content are caused by differences in accumulation of malic acid in the vacuole. This accumulation may be caused by a gene that is responsible for

  1. Do They Keep Coming? The Emergence of New Spatial Mobility Patterns in Macaé/RJ

    Full Text Available Macaé is the “Oil Capital” of Brazil: a city of opportunity, full of jobs andwhere royalties fatten public coffers or that is the image presented in the media that has attracted thousands of migrants to Macaé. This study investigated why people feel that migrants keep coming to Macaé even though recent statistics show that in-migration to the city has decreased. Also, new forms of spatial mobility of the population have emerged so that Macaé can be characterized as region of polar attraction. Commuting from neighbouring cities is a common pattern in metropolitan areas and in Macaé it is associated to the high cost of living and violence present there so that many workers have their residence elsewhere, especially Rio das Ostras. In addition to daily commuting, another kind was detected in the research: "long distance commuting". This kind of commuting is associated basically to specific characteristics of the labour market in the oil sector involving periods on the platforms interspaced with periods off duty on the mainland as well as outsourcing practices. A third trend noted was the presence of a significant number of transients, who keep coming to the city in large numbers but do not lay residence.

  2. Aliphatic and aromatic hydrocarbons in tropical recent sediments of Campos dos Goytacazes, RJ, Brazil

    2003-01-01

    Full Text Available Sediment samples from the Imbé, the Urubu and the Ururaí rivers and from Lake de Cima were studied. These sites are located in the county of Campos dos Goytacazes, Rio de Janeiro, Brazil. Aliphatic and aromatic fractions were analyzed by GC-FID and GC-MS in order to gather information on the degree of contamination by anthropogenic activities and other biogenic contributions. Concentrations of total aliphatic and aromatic hydrocarbons were 1.2, 2.8, 5.8 and 4.3 mug g-1 and 74, 30, 722 and 340 ng g-1 in the Imbé, Ururaí, Urubu rivers and Lake de Cima, respectively. The C20 highly branched isoprenoid alkane was identified in the Urubu sediment. There were no hopanes or steranes in any sample. Anthropogenic aromatic compounds, detected at trace levels, were observed only in the Imbé and in Lake de Cima (227 ng g-1. The fluoranthene/pyrene rate for Lake de Cima was 4.2, suggesting a combustion origin for the PAH. This data is consistent with the frequently sugar cane burning practice that occurs in this region. A greater input from higher plants was observed in the Urubu, Imbé and Lake de Cima sediments; on the other hand, the aquatic input predominates for Ururaí. In summary, Lake de Cima sediment is considered very slightly polluted, while the others are unpolluted.

    Full Text Available The Juturnaiba Dam, located between the municipalities of Silva Jardim and Araruama, is the only fresh water source supplying the entire Lake District, State of Rio de Janeiro. The objective of this research was to evaluate the water quality of the Juturnaiba reservoir through physical, chemical and microbiological analyses conducted upstream and downstream in the rivers, comparing them in to identify its hydrodynamics. Six collections were made in six strategic points. The Capivari river was the tributary with greater restrictions on water quality. The river with better water quality was the São João River.

    Lignin phenols were measured in the sediments of Sepitiba Bay, Rio de Janeiro, Brazil and in bedload sediments and suspended sediments of the four major fluvial inputs to the bay; São Francisco and Guandu Channels and the Guarda and Cação Rivers. Fluvial suspended lignin yields (Σ8 3.5-14.6 mgC 10 g dw -1) vary little between the wet and dry seasons and are poorly correlated with fluvial chlorophyll concentrations (0.8-50.2 μgC L -1). Despite current land use practices that favor grassland agriculture or industrial uses, fluvial lignin compositions are dominated by a degraded leaf-sourced material. The exception is the Guarda River, which has a slight influence from grasses. The Lignin Phenol Vegetation Index, coupled with acid/aldehyde and 3.5 Db/V ratios, indicate that degraded leaf-derived phenols are also the primary preserved lignin component in the bay. The presence of fringe Typha sp. and Spartina sp. grass beds surrounding portions of the Bay are not reflected in the lignin signature. Instead, lignin entering the bay appears to reflect the erosion of soils containing a degraded signature from the former Atlantic rain forest that once dominated the watershed, instead of containing a significant signature derived from current agricultural uses. A three-component mixing model using the LPVI, atomic N:C ratios, and stable carbon isotopes (which range between -26.8 and -21.8‰) supports the hypothesis that fluvial inputs to the bay are dominated by planktonic matter (78% of the input), with lignin dominated by leaf (14% of the input) over grass (6%). Sediments are composed of a roughly 50-50 mixture of autochthonous material and terrigenous material, with lignin being primarily sourced from leaf.

    Full Text Available Large extensions of the coastal sandy soils (restinga vegetation of the northern region of Rio de Janeiro had been eliminated since the colonization, with replacement of the native vegetation by sugarcane cultivation followed by agricultural expansion. The Açu Lagoon State Park (PELAG was created with the goal of preserve part of the remaining ecosystem, sandbanks, swamps, marshes and coastal lagoons, reminiscent of ecosystems that existed in the region before its degradation. In order to have a better characterization of the area delimited for its implantation, the present work has the objective of mapping the land use in the Park. The classification was performed through supervised classification with visual interpretation pixel by pixel and applying the maximum likelihood, where the following categories were considered: water, wet soils, vegetation, exposed soils and pastures. The results obtained were consistent with the reality observed in the field. It was observed that the highest percentage of soil cover is composed of pasture (27.8%, followed by wetlands (25.74% and wet soil (22.22%. Approximately 16.0% of the area of the park is covered by vegetation, characterized mainly by coastal sandy soils (restinga. A large part of the park area is devoid of vegetation cover, and it is necessary to recompose it, mainly that from the permanent preservation areas.

    it was investigated the transport of the series natural radionuclides and the earth rare light elements in a coastal lagoon system, located in a monazite rich region, in the coast north region of Rio de Janeiro state. The lagoon water showed off abnormal concentrations of radium isotopes and of the earth rare light elements (ERLEs). The longitudinal gradient of the Ra, of the ERLEs and of the major ion concentration's, whose data were obtained during two and half years of the research at the place, and the statistical analysis pointed to two mainly source as responsible for the water lagoon composition - the marine and the underground waters. The underground water supplies the radionuclides and ERLEs, possibly originated by monazite lixiviation. Based on the water speciation modeling, the results of laboratory adsorption on sediment experiments and the sediment characterization, the behavior of the radio isotopes, the ERLEs, U, Th e Pb-210, along of the lagoon, are discussed. It is also discussed the role of the aquatic macrophyte Typha dominguesis Pers in the nuclide uptake and the following liberation. (author)

    1994-12-01

    Full Text Available Within the scope of the MAR-14 Project, part of the Brazil-Germany Bilateral Agreement in Marine Sciences, an oceanographic survey aboard the R/V Victor Hensen was carried out in Brazilian coastal waters between Santos (23º56'S and Rio de Janeiro (22º54'S, from January 15 to January 22,1991. In this article we report results of preliminary analyses of the hydrographic data collected with CTD, STD, Nansen bottles and XBT's. These preliminary results show intense stratification in the first 200 m depth, and the penetration of the Brazil Current deep into the continental shelf region. Two eddy-like features were detected. The first one, anticyclonic, was located in the northern part of the domain and confined to the uppermost 200 m. The second, a cyclonic vortex, was found a little to the southwest below 200 m and extending downwards to about 800 m depth. Water mass analyses based on T-S diagrams suggest that the interface between the South Atlantic Central Water (SACW and the Antarctic Intermediate Water (AIW is located at about 500 m depth. One important aspect of this study is that this was the first time a high resolution survey with a CTD probe was realized along the eastern Brasilian Coast, south of Cabo Frio.Como parte do projeto MAR-14, componente do Acordo Bilateral Brasil-Alemanha em Ciências Marinhas, uma campanha oceanógrafica a bordo do R/V Victor Hensen foi realizada em águas costeiras do Brasil entre Santos (23º56'S, de 15 a 22 de janeiro de 991. Neste artigo reportamos resultados de análises preliminares dos dados hidrográficos coletados com o auxílio de CTD, STD, garrafas de Nansen e XBT's. Esses resultados preliminares mostram uma intensa estratificação nos primeiros 200 m de profundidade, e a penetração da corrente bem adentro da região sobre a plataforma continental. Duas estruturas com características de vórtices de meso-escala foram detectadas. O primeiro, anticiclônico, estava localizado na parte norte da rede de estações e confinado praticamente nos primeiros 200 m de profundidade. O Segundo, um vórtice ciclónico, foi encontrado um pouco para o sudoeste e abaixo dos 200 m, estendendo-se para baixo até cerca de 800 metros. Análises de Massa de água baseadas em diagramas T-S sugerem que a interface entre a Água Central do Atlântico Sul (ACAS e a Água Intermediária Antártica (AIA se encontrava em aproximadamente 500 m de profundidade. Um aspecto importante desse cruzeiro que deve ser ressaltado é que, esta foi a primeira vez em que um sensor do tipo CTD foi utilizado com essa resolução ao longo da costa leste do Brasil, abaixo de Cabo Frio.

    1980-06-01

    Full Text Available A mesosoale study was made of the Ilha Grande area. The local circulation described through -progressive vector diagrams showed a clochwise bottom circulation determined in June 1976, while in the upper 10 m the direction of the flow entering the Ilha Grande Bay was towards the center in the west and towards the Marambaia sandbank in the east side of the Bay. Short periods and amplitude fluctuations were evaluted using power spectral analysis, Fourier and Maximum Entropy Method, which showed that in the upper 10 m predominant periods decrease from 1.1h (A = 6.3cm sec-1 (position = 3C to 1.0h (A = 7.4 cm sec-1 (position = 2D and increase to 5.8h (A = 6.8 cm., sec-1 (position = ID, while at the bottom layer the predominant period increases from 0.4 h (A = 5.0 cm sec-1 (position = 3G to 6.4h (A = 7.0 cm sec-1 (position = 2G and to 4.4h (A = 7.9 cm sec-1 (position = 1G . From the original data it has been possible to determine an "intense pulsation" between 30-70 cm sec-1 in the upper 10 m with about 1.0h period and 10-20 min duration in all the stations.

    Full Text Available As organizações familiares estão presentes em todo contexto mundial, sendo micro ou pequenas empresas, são elas as responsáveis por grande parte da economia em no Brasil, elas surgem a partir de um sonho e do esforço de empreendedores que buscam construir um negócio lucrativo que dure por gerações. Entretanto, mesmo sendo tão representativas essas empresas enfrentam dificuldades durante a sucessão, que devido à falta de planejamento sucessório e da preparação dos futuros herdeiros muitas delas não chegam a segunda e a terceira geração. Com este trabalho foi possível analisarmos o processo sucessório e a importância do planejamento e da profissionalização dos sucessores. Os dados foram coletados por meio de entrevistas com base em um roteiro de perguntas semi estruturadas realizadas com os sucessores de duas pequenas empresas familiares em Campos dos Goytacazes que já passaram pelo processo sucessório. Apesar de não ter ocorrido um planejamento sucessório o fato dos sucedidos levarem seus herdeiros para a empresa quando crianças e os familiarizando ao negócio contribuiu para que a transição ocorresse sem muitos impactos dando continuidade a um empreendimento próspero.

    Full Text Available Thirty sediment samples were collected in Guanabara Bay in August, November and December 2005. The material was analyzed for organic matter, total and faecal coliforms, heterotrophic bacteria, bacterial respiratory activity, esterase activity and electron transport system activity. The organic matter in the superficial sediments (2 cm ranged from 4 to 6%. The highest level of total coliforms and faecal coliforms were 1.7 x 10(5 MPN/g and 1.1 x 10³ MPN/g, respectively. Heterotrophic bacteria presented the highest values at station 7 (4.1 x 10(6 CFU/g and the lowest values at station 3 (7 x 10(4 CFU/g (northwestern part of Guanabara Bay. Esterase enzyme activity showed activity in the sediment of all 30 stations. Electron transport system activity ranged between 0.047 muL O2/h/g and 0.366 muL O2/h/g at six stations. The benthic microbial foodweb is anaerobic. Anaerobic processes such as fermentation, denitrification and sulphate-reduction are responsible for the biogeochemical cycles in the sediment of Guanabara Bay. The input of untreated sewage in the Mangue Channel outflow in Guanabara Bay has favored the increase of the organic load, and the maintenance of the total coliforms and faecal coliforms in the sediment. Faecal coliforms have been reported to be a good indicator of aquatic pollution and organic contamination in the water column, but total coliforms may be an ideal candidate group for sediment quality tests as well.Trinta amostras de sedimento foram coletadas na Baía de Guanabara em agosto, novembro e dezembro de 2005. Foram analisados matéria orgânica, coliformes totais e fecais, bactéria heterotrófica, atividade respiratória bacteriana, atividade de esterase e do sistema transportador de elétrons. A matéria orgânica no sedimento superficial variou entre 4 e 6%. O maior nível de coliformes totais e fecais foi 1.7 x 10(5 MPN/g e 1.1 x 10³ MPN/g, respectivamente. Bactérias heterótrofas mostraram o maior valor na estação 7 (4.1 x 10(6 CFU/g e o menor na estação 3 (7 x 10(4 CFU/g (nordeste da Baía de Guanabara. A enzima esterase mostrou atividade em todos os sedimentos das 30 estações. A atividade do sistema transportador de elétrons variou entre 0.047 miL O2/h/g e 0.366 miL O2/h/g em seis estações. A cadeia microbiana bêntica é anaeróbia. Os processos como fermentação, desnitrificação e sulfato redução são responsáveis pelos ciclos biogeoquímicos no sedimento da Baía de Guanabara. O despejo de esgoto não tratado no Canal do Mangue da Baía de Guanabara tem favorecido o aumento da carga orgânica e a manutenção de coliformes totais e fecais no sedimento. Os coliformes fecais são bons indicadores de poluição e contaminação orgânica na coluna de água, mas os coliformes totais também poderão ser um grupo candidato para testes de qualidade de sedimento.

    Full Text Available RESUMO Foi analisado o efeito de trilhas sobre a comunidade de artrópodes de serrapilheira em duas trilhas do Parque Nacional da Tijuca. Amostras de serrapilheira foram coletadas em duas cotas altitudinais (650 e 850 m anm e em três classes de distância (0, 5 e 10 m. Os artrópodes foram identificados ao nível de ordem. Foram amostrados 4.491 indivíduos de 19 taxa, sendo Orthoptera a mais frequente. Foram encontradas diferenças significativas no número de táxons entre trilhas, possivelmente como resposta a um efeito causal da estrutura e da composição florística das trilhas e das cotas. A trilha que apresentou os maiores valores de riqueza foi a do Bico do Papagaio, diferindo da trilha do Pico da Tijuca. Concluiu-se que as diferenças encontradas podem estar relacionadas com o grau de perturbação diferenciado que as duas trilhas sofrem. No entanto, análises mais detalhadas poderão tornar os resultados mais claros.

    Full Text Available Much time and resources have been invested in understanding plankton dynamics in Guanabara Bay (Brazil, but no attention has been devoted to the protozooplankton. To fulfill this lacuna, abundance and composition of protozooplankton were investigated from January to December - 2000 in fortnightly surface water samplings at two distinct water quality sites (Urca - closer to the bay entrance, more saline and cleaner waters; Ramos - inner reaches, hypereutrophic waters. The density at Urca (10³ - 10(5 cell.l-1 was one to three orders of magnitude lower than at Ramos (10(4 - 10(5 cell.l-1. A seasonal trend for nanoplankton and protozooplankton was more evident at Urca, but both sites had lower densities during the colder period. Small heterotrophic dinoflagellates (20-30 mm were dominant in over 50% of the samples. The protozooplankton abundance and composition reflected the distinct trophic conditions states found at the bay. During the wet-warm season, non-oligotrich ciliates were representative of Ramos site with Gymnodiniaceae dinoflagellates, while tintinnids and heterotrophic dinoflagellates were predominantly found at Urca mainly during the dry-cold season. This first descriptive study towards the understanding of the intricate relationships among the microbial food web components reveals that protozooplankton can be a good indicator of water quality conditions at the bay.Muito tem sido investido para entender a dinâmica do plâncton da Baía de Guanabara (Brasil, estuário tropical com sérios problemas ambientais, mas pouco se sabe sobre o protozooplâncton. Preenchendo esta lacuna, a composição e abundância do protozooplâncton (ciliados, flagelados heterotróficos foram investigadas em 2000, por meio de amostragens subsuperficiais, quinzenais, em dois locais com qualidade distinta de água (Urca - entrada da baía, águas mais salinas e limpas; Ramos - região mais interna, águas hipereutróficas e menos salinas. A densidade na Urca (10³-10(5 cel.L-1 foi inferior à de Ramos (10(4-10(5 cel.L-1, com sazonalidade para o nanoplâncton e protozooplâncton mais evidente, menores valores durante o período mais frio (abril a agosto. Pequenos dinoflagelados (20-30 mm dominaram mais de 50% das amostras. A abundância e composição refletiram o distinto estado trófico na baía (análise fatorial de correspondência: 56%. Ciliados não oligotríqueos (Vorticellidae, Dysteriidae, Didiniidae e Gymnodiniaceae foram representativos de Ramos na estação quente-úmida (outubro - março, enquanto tintinídeos (Codonellopsidae, Metacyclididae, Tintinnidae, Undellidae e dinoflagelados (Oxyphysaceae, Ebriidae, Protoperidiniaceae, Noctilucaceae representativos da Urca, principalmente na estação fria-seca (abril - setembro. Este primeiro estudo descritivo, fundamental para o entendimento das relações na teia alimentar microbiana, revelou o protozooplâncton como bom indicador das condições da qualidade da água da baía.

    Maywood Chemical Works (MCW) of Maywood, New Jersey, generated process wastes and residues associated with the production and refining of thorium and thorium compounds from monazite ores from 1916 to 1956.MCW supplied rare earth metals and thorium compounds to the Atomic Energy Commission and various other government agencies from the late 1940s to the mid-1950s. Area residents used the sandlike waste from thisthorium extraction process mixed with tea and cocoa leaves as mulch in their yards. Some of these contaminated wastes were also eroded from the site into Lodi Brook. At the request of the US Department of Energy(DOE), a group from Oak Ridge National Laboratory conducts investigative radiological surveys of properties in the vicinity of MCW to determine whether a property is contaminated with radioactive residues, principally 232 Tb, derived from the MCW site. The survey typically includes direct measurement of gamma radiation levels and soil sampling for radionuclide analyses. The survey of this site, 48 Schlosser Drive, Rochelle Park, New Jersey (RJO05), was conducted on July 14, 1991. Results of the survey demonstrated no radionuclide concentrations in excess of the DOE Formerly Utilized Sites Remedial Action Program criteria. The radionuclide distributions were not significantly different from normal background levels in the northern New Jersey area
