    Bio fuels are important tools in reducing emissions of greenhouse gases (GHG); however, to minimize the conflict with food crops, energy crops with high efficiency and capacity to absorb Co2, such as the oil palm, should be prioritized. The European Union intends to replace 10% of liquid fossil fuel demand with bio fuels by 2020. According to studies conducted by the European Commission, this will entail the annual import of more than 3 million tonnes of palm oil, the most produced and least expensive vegetable oil in the world. 87% of global production comes from Indonesia and Malaysia, where the relentless expansion of oil palm cultivation has caused extensive forest devastation, threatening biodiversity and increasing GHG emissions. The Netherlands, a large importer of oil palm products, developed a methodology (Cramer) for the certification of sustainable bio energy production, assessing economic, social, environmental aspects, as well as GHG emissions, throughout the supply chain. It sets a mandatory minimum 30% reduction of GHG emissions in the bio-energy chain for use in transport and 70% for use in heat and power generation, as compared to the chain of the fossil counterpart. This dissertation shows that oil and bio diesel (ethyl ester) from palm grown in the Amazon meets this GHG mitigation criterion when degraded areas are utilized for cultivation, but not when forests are razed for that purpose.

    The analysis of drainage net allows to identify features of relief symmetry and/or not symmetry and know its morpho structure (high and low structural). The interpretation of relief and drainage texture elements at Landsat/ETM7+ satellite images allows to identify the geo environmental zoning. The integration between morpho structural maps and geo environmental zones maps produces sustainable capacity maps. In the Bolivia-Brazil Gas Pipeline influence area, the evaluation of sustainable capacity shapes the interrelation among gas pipeline and physical environment and allows classify more geological and geotechnical favorable areas to gas pipeline maintenance. Gas pipeline regions located at 'High Sustainable Capacity' need few maintenance. However, gas pipeline regions at 'Low/Very Low Sustainable Capacity' need constant investment and monitoring.

    The natural resources have if turned more and more scarce, should be taken in your consideration possible exhausted. With that threat, alternatives are looked for so that the socioeconomic development is maintainable. As the impact of the section agroindustrial in the environmental deterioration is significant, the environmental externalisation of the productive process and the need of economical internalization of those effects should be considered. The introduction of the natural capital in the economical analysis is made necessary since the costs of the environmental degradation and of the consumption of natural resources they have not been added in those processes, being evaluated the flows of natural stocks and contributing to the definition of a maintainable scale of the economy. When these industrial organizations embrace a great productive area of the Country, as it is the case of the compound of the alcohol industry, the problems caused for the it burns of the sugar cane plantation they become fundamental. Now, there is an emergent change of paradigms in the society, in that is necessary to notice the group of values that they address our economical development and our relationship with the natural atmosphere.

    Studies on the behaviour and transport of {sup 137} Cs in urban areas, including, resuspension and deposition experiments, {sup 137} Cs uptake by leafy vegetables and small domestic animals that accidentally ingested contaminated soil, were performed in a house located at 57{sup t}h Street near the main focus of contamination. The resuspension of surface soil did not contribute much to the spreading of the radionuclide in Goiania, but can lead to the local contamination of vegetables, equipment, structures and other environmental surfaces. The mechanism also presented a seasonal effect. The soil is an important medium for the uptake of {sup 137} Cs by small domestic animals. The street dust sampling is a suitable method to assess the dispersion of {sup 137} Cs in urban areas. After 10 years, the radionuclide activity concentration is restricted only to the initially impacted area an it is decreasing with time. (author) 9 refs., 2 figs, 2 tabs.

    For elaboration of contingency plans it is necessary to execute the mapping of sensitive areas to oil spill, as well as to create suitable forecast models for oil pollution movements. These models should start from a consistent database, so that it can encompass the several phases of the environmental monitoring. In both cases hydrodynamic data are essential. The analysis of hydrodynamic parameters is also an important phase for the knowledge of the Holocene evolution of the study area, as well as for execution of a suitable development policy to be applied on the area. The activities developed in this research involve collection of data 'in situ' at the Galinhos-Guamare and Diogo Lopes lagoons, as well as data manipulation referring to the littoral drift collected monthly along the North coast of the state of Rio Grande do Norte by members of the Grupo de Geologia e Geofisica Marinha e Melhoramento Ambiental (GGEMMA) from UFRN.

    Na-ion batteries are emerging as one of the most promising energy storage technologies, particularly for grid-level applications. Among anode candidate materials, hard carbon is very attractive due to its high capacity and low cost. However, hard carbon anodes often suffer a low first-cycle Coulombic efficiency and fast capacity fading. In this study, we discover that doping graphene oxide into sucrose, the precursor for hard carbon, can effectively reduce the specific surface area of hard carbon to as low as 5.4 m(2)/g. We further reveal that such doping can effectively prevent foaming during caramelization of sucrose and extend the pyrolysis burnoff of sucrose caramel over a wider temperature range. The obtained low-surface-area hard carbon greatly improves the first-cycle Coulombic efficiency from 74% to 83% and delivers a very stable cyclic life with 95% of capacity retention after 200 cycles.

  12. R2NA: Received Signal Strength (RSS Ratio-Based Node Authentication for Body Area Network

    Full Text Available The body area network (BAN is an emerging branch of wireless sensor networks for personalized applications. The services in BAN usually have a high requirement on security, especially for the medical diagnosis. One of the fundamental directions to ensure security in BAN is how to provide node authentication. Traditional research using cryptography relies on prior secrets shared among nodes, which leads to high resource cost. In addition, most existing non-cryptographic solutions exploit out-of-band (OOB channels, but they need the help of additional hardware support or significant modifications to the system software. To avoid the above problems, this paper presents a proximity-based node authentication scheme, which only uses wireless modules equipped on sensors. With only one sensor and one control unit (CU in BAN, we could detect a unique physical layer characteristic, namely, the difference between the received signal strength (RSS measured on different devices in BAN. Through the above-mentioned particular difference, we can tell whether the sender is close enough to be legitimate. We validate our scheme through both theoretical analysis and experiments, which are conducted on the real Shimmer nodes. The results demonstrate that our proposed scheme has a good security performance.

    Juvenile blue crabs, Callinectes sapidus, extensively utilize oligohaline and freshwater regions of the estuary. With a presumptively larger surface-area-to-body weight ratio, juvenile crabs could experience osmo- and ionoregulatory costs well in excess of that of adults. To test this hypothesis, crabs ranging over three orders of magnitude in body weight were acclimated to either sea water (1,000 mOsm) or dilute sea water (150 mOsm), and gill surface area, water and sodium permeabilities (calculated from the passive efflux of 3H2O and 22Na+), gill Na+, K+ -ATPase activity and expression were measured. Juveniles had a relatively larger gill surface area; weight-specific gill surface area decreased with body weight. Weight-specific water and sodium fluxes also decreased with weight, but not to the same extent as gill surface area; thus juveniles were able to decrease gill permeability slightly more than adults upon acclimation to dilute media. Crabs crabs > 5 g in both posterior and anterior gills. Acclimation to dilute medium induced increased expression of Na+, K+ -ATPase and enzyme activity, but the increase was not as great in juveniles as in larger crabs. The increased weight-specific surface area for water gain and salt loss for small crabs in dilute media presents a challenge that is incompletely compensated by reduced permeability and increased affinity of gill Na+, K+ -ATPase for Na+. Juveniles maintain osmotic and ionic homeostasis by the expression and utilization of extremely high levels of gill Na+, K+ -ATPase, in posterior, as well as in anterior, gills.

    The structure and immunolocalization of the ion transporters Na(+) ,K(+) -ATPase (NKA), Na(+) /H(+) exchanger (NHE3) and vacuolar-type H(+) -ATPase (VHA) were examined in the gills of teleosts of the family Blenniidae, which inhabit rocky shores with vertical zonation in subtropical seas. These features were compared among the following species with different ecologies: the amphibious rockskipper blenny Andamia tetradactylus, the intertidal white-finned blenny Praealticus tanegasimae and the purely marine yaeyama blenny Ecsenius yaeyamaensis. Light and electron microscopic observations indicated that thick gill filaments were arranged close to each other and alternately on two hemibranches of a gill arch in the opercular space of A. tetradactylus. Many mucous cells (MC) and mitochondrion-rich cells (MRC) were present in the interlamellar regions of the gill filament. An immunohistochemical study demonstrated that numerous NKA, NHE3 and some VHA were located predominantly on presumed MRCs of gill filaments and at the base of the lamellae. Analyses using serial (mirror image) sections of the gills indicated that only a few NKA immunoreactive cells (IRC) were colocalized with VHA on some MRCs in the filaments. In the gills of P. tanegasimae, NKA- and NHE3-IRCs were observed in the interlamellar region of the filaments and at the base of the lamellae. VHA-IRCs were located sparsely on the lamellae and filaments. In the gills of E. yaeyamaensis, the lamellae and filaments were thin and straight, respectively. MCs were located at the tip as well as found scattered in the interlamellar region of gill filaments. NKA-, NHE3- and VHA-IRCs were moderately frequently observed in the filaments and rarely on the lamellae. This study shows that the structure and distribution of ion transporters in the gills differ among the three blennid species, presumably reflecting their different ecologies. © 2012 The Authors.

    Full Text Available In agriculture, there is a difference between average yield obtained by farmers and crop potential. There is technology available to increase yields, but not all farmers have access to it and/or use this information. This clearly characterizes an extension and technology transference problem. There are several technology transfer systems, but there is no system to fit all conditions. Therefore, it is necessary to create extension solutions according to local conditions. Another rural extension challenge is efficiency, despite continuous funding reductions. One proposal that has resulted from extension reform worldwide has suggested integration between the public and private sectors. The public universities could play the role of training and updating technical assistance of human resources, which is the one of the main aspects that has limited technology transfer. The objective of this study was to identify approaches to promote technology transfer generated in Brazilian public universities to rural areas through literature review. An experimental approach of technology transfer is presented here where a Brazilian university extension Vice-chancellor incorporates professionals from consolidated research groups according to demand. In this way, public universities take part of their social functions, by integrating teaching, research, and extension.Em agricultura, há diferenças entre a produtividade média obtida pelos produtores e o potencial produtivo dos cultivos. Há informação tecnológica disponível para aumentar a produtividade, mas nem todos os produtores têm acesso e/ou usam a informação. Isso caracteriza claramente um problema de extensão e transferência de tecnologia. Há vários sistemas de transferência de tecnologia, mas, como não há sistema que se ajuste a todas as condições, é necessário criar alternativas adequadas às condições de cada local.

    Full Text Available The determination of solar irradiation is crucial when planning the installation of solar systems. There are different GIS models for determining solar irradiation, which differ from each other in terms of input data, hardware requirements, performance, reliability and suitability, depending on the specificity of the study area and the nature of the study. Because of their diversity, urban areas pose a greater challenge for the estimation of the potential of the received solar energy. In the article we offered a methodology for determining the irradiation of urban area roofs using the GRASS GIS model r.sun, which makes the computation with high resolution spatial, atmospheric and meteorological data. The used input data is freely available for the entire territory of Slovenia. The proposed methodological approach was tested in the area of the town quarter Rožna dolina with the northern part of Vič. The area is very diverse according to the typology of the built objects, the land cover and altitude differences.

    The National Commission of Nuclear Energy (CNEN) is responsible in Brazil for the activities of licensing and control of radioactive installations in the radiotherapy medical area. The majority of these activities are developed by CNEN Co-ordination of Radioactive Installations (CORAD). One of the necessary stages for the development of licensing and control activities is the inspection of radiotherapy services (clinics and hospitals). Almost all of these inspections are carried out by CNEN Inst. of Radiation Protection and Dosimetry (IRD), through its Service of Medical Physics in Radiotherapy and Nuclear Medicine (SEFME). This work makes a survey of the main nonconformities found during ten years of inspections in radiotherapy services (1995 - 2004) and analyses the efficiency of these inspections in making the radiotherapy services develop their activities according to the norms in vigour in the country and adopt corrective actions against, at least, the nonconformities evidenced by CNEN inspectors. Additionally, it analyses the possibility of improvement and / or the optimisation of the process, through a procedure able to be unified and controlled, aiming a prompt communication to those involved in the licensing process (SEFME and CORAD) about the attendance by the radiotherapy services to the non-conformity items observed during the inspection.

  1. Ghrelin and GHS-R1A signaling within the ventral and laterodorsal tegmental area regulate sexual behavior in sexually naïve male mice.

    In addition to food intake and energy balance regulation, ghrelin mediate the rewarding and motivational properties of palatable food as well as addictive drugs. The ability of ghrelin to regulate reinforcement involves the cholinergic-dopaminergic reward link, which encompasses a cholinergic projection from the laterodorsal tegmental area (LDTg) to the ventral tegmental area (VTA) together with mesolimbic dopaminergic projections from the VTA to the nucleus accumbens (NAc). Recently, systemic ghrelin was shown to regulate sexual behavior and motivation in male mice via dopamine neurotransmission. The present study therefore elucidates the role of ghrelin and ghrelin receptor (GHS-R1A) antagonist treatment within NAc, VTA or LDTg for sexual behavior in sexually naïve male mice. Local administration of the GHSR-1A antagonist, JMV2959, into the VTA or LDTg was found to reduce the preference for female mice, the number of mounts and the duration of mounting as well as to prolong the latency to mount. This was further substantiated by the findings that ghrelin administration into the VTA or LDTg increased the number of mounts and the duration of mounting and decreased the latency to mount. Moreover, ghrelin administered into the LDTg increased the preference for female mice. Accumbal administration of ghrelin increased whereas GHS-R1A antagonist decreased the intake of palatable food, but did not alter sexual behavior. In males exposed to sexual interaction, systemic administration of ghrelin increases whereas JMV2959 decreases the turnover of dopamine in the VTA. These data suggest that ghrelin signaling within the tegmental areas is required for sexual behavior in sexually naïve male mice. Copyright © 2015 The Authors. Published by Elsevier Ltd..

    In the northern area of Campos Basin salt gliding/spreading processes promoted the break-up and transport of Cretaceous and Tertiary rocks overlying the evaporites. This process is known as raft tectonics, and it represents the most extreme form of thin-skinned extension above the salt decollement surface. Three distinct geotectonic domains were recognized that formed in response to the raft tectonics. The first one, confined to the shallower shelf portion of the basin, is characterized by minor extension (pre-raft domain), probably because of small salt thickness and low gradient. In the second domain (or disorganized rafts domain), located in distal platformal and slope areas, seismic sections show the occurrence of blocks or rafts with angular shapes, sometimes imbricated and frequently discontinuous. In the third domain, or domain of organized rafts, located in bacinal region, seismic sections show a more continuous raft pattern, often folded because of salt compression in the distal portions of the basin. The main purposes of this work is to characterize these three tectonic domains distinguished by raft tectonics, as well as their importance in hydrocarbon accumulations in calcarenites. (author)

    Area postrema (AP) is a circumventricular organ plays an important role in sodium homeostasis and cardiovascular regulation. Since sleep deficiency will cause cardiovascular dysfunction, the present study aims to determine whether sodium level would significantly alter in AP following total sleep deprivation (TSD). Sodium level was investigated in vivo by time-of-flight secondary ion mass spectrometry (TOF-SIMS). Clinical manifestation of cardiovascular function was demonstrated by mean arterial pressure (MAP) values. Results indicated that in normal rats, TOF-SIMS spectrum revealed a major peak of sodium ion counting as 5.61 × 10 5 at m/ z 23. The sodium ions were homogeneous distributed in AP without specific localization. However, following TSD, the sodium intensity was relatively increased (6.73 × 10 5) and the signal for sodium image was strongly expressed throughout AP with definite spatial distribution. MAP of TSD rats is 138 ± 5 mmHg, which is significantly higher than that of normal ones (121 ± 3 mmHg). Regarding AP is an important area for sodium sensation and development of hypernatremic related sympatho-excitation; up-regulation of sodium expression following TSD suggests that high sodium level might over-activate AP, through complex neuronal networks involving in sympathetic regulation, which could lead to the formation of TSD relevant cardiovascular diseases.

    Variations in the chemical composition of soils are used to characterize sub-areas geochemically - homogenous. The application of this methodology in a tropical humid region of accentuated topography constitute the principal objective of the present research. Samples of red latosols (Horizon B) developed over granite, sandstone and basalt occurring in the Central Granite Region of the Serra dos Carajas, Para State, Brazil were analized for the elements Si, Al, Fe, Mn, Na, K, Cu e Zn, by atomic absorption spectrophotometry. Based on the criterion of similarity in the chemical composition (Cluster Analysis, Factor Analysis) the soils were separeted in to different groups. The geographical distribution of the different groups permit the establishment of a close relationship between the different parent lithologies and their corresponding soils. (author)

Badania przeprowadzono na terenie zurbanizowanym, na którym dokonano zmian rzeźby oraz sposobu użytkowania terenu. Spowodowało to pojawieniem się problemów z odwodnieniem terenu, przede wszystkim w czasie wzmożonego zasilania z opadów deszczu i roztopów śniegu. W celu określenia przyczyn występujących problemów porównano rzeźbę terenu oraz wyznaczono kierunki odpływu wód powierzchniowych przed i po zagospodarowaniu działki d (Ryc. 1.

    emergência médica na Grande São Paulo.The present paper analyzed the emergency medical system in the Metropolitan Area of São Paulo during the year 1999 through the exam of all the pertinent laws, the description of the attendance process of the Regional Controlling Unit (Plantão Controlador Regional - PCR, and the verification of the adequacy of the adopted procedures to the norms that regulate the sector and to an efficient attendance of the patients. Documents were analyzed, interviews were carried out and the functioning of the system was observed in the PCR and in three general hospitals. The paper describes the oral history of the creation of the system and the services routine. It was observed that there was personnel shortage in the PCR and that the doctors did not follow the same routine of procedures. It was also verified that many people, including the doctors on duty, did not know what the PCR was, and that transfers were sometimes impossible due to lack of transportation. Furthermore, the Medical Files and Statistics Services of the researched hospitals are outdated and there is shortage of material and human resources. Although the size of the sample does not allow generalizations, it could be observed that there was lack of beds in the Neonatal ICU, and that the most frequent reasons for the request of resources were lack of beds and equipment, faulty equipment and shortage of personnel. These requests often received a negative answer at first, with the most frequent reasons being lack of beds, unavailable equipment or transport. Most cases arrived at the PCR after the professionals in charge had tried to solve the problem on their own under the justification of delay in solving the case. Based on the rules of the system and on the analysis of international experiences, the paper provides suggestions for the efficacious implementation of a metropolitan emergency system in the metropolitan area of São Paulo.

A pesquisa ocorreu mediante dinâmicas de grupo no contexto de algumas técnicas de gestão da qualidade utilizadas na norma ISO 9001. Verificou-se pouca interação entre os atores locais em termos da implantação de ações de recuperação ambiental. O custo econômico de implantação e manutenção do PRAD representaram fatores limitantes. A falta de perspectiva de considerar o PRAD como fornecedor de área produtiva, também foi considerado um entrave na perspectiva dos produtores rurais. A pesquisa fortaleceu as ações da UFMT, visando diminuir a degradação que ocupa em torno de um terço do território de Mato Grosso.

    Full Text Available A six year-long hydrochemical monitoring operation was conducted in Vrancea seismic zone (Romania, addressing a saline spring that proved to be suitable for Na-K-Mg geothermometry diagnosis. During the considered time-interval (2003–2009, only one important earthquake (mb=5.8 occurred in Vrancea region, this circumstance providing an unambiguous reference-moment between pre-seismic and post-seismic periods. On occurrence of that earthquake, an anomalous fluctuation of the Na-K temperature was detected – a result largely similar to previous ones recorded worldwide (California, southwest Egypt, northeast India. Yet such fluctuations may not necessarily be induced by earthquake-associated processes: they can occur also "routinely", possibly reflecting some environmental, meteorologically-induced "noise". It was therefore important to examine whether the variations observed in the data values could be plausibly related to a seismogenesis process. By additionally investigating (in a "scattterplot" diagram the correlation between the Na-K temperatures and the values of a so-called "maturity index", a specific pattern emerged, with pre-seismic data-points plotting in a distinct domain of the diagram; moreover, those data-points appeared to describe a "drift away" pathway with respect to the remaining data-points "cluster", recorded during the subsequent 4 years of post-seismic monitoring. The "drift away" pattern persistently evolved for at least 18 months, ending just before the mb=5.8 earthquake and consequently suggesting the existence of some kind of long-term precursory phenomenon.

There was no apparent or documented relationship of chronic autoimmune thyroiditis prevalence to the proximity to the petrochemical complex.OBJETIVO: Analisar a prevalência populacional de tireoidite crônica autoimune (tireoidite de Hashimoto na área vicinal ao Polo Petroquímico de Capuava comparativamente a área controle em São Bernardo Campo. CASUÍSTICA E MÉTODOS: Em ambas as áreas urbanas foram incluídos, aleatoriamente, indivíduos adultos que, de forma voluntária, concordaram em participar do estudo, estratificado por idade (20 a > 70 anos e sexo (mulheres 80%, homens 20%. Na área Polo foram incluídos 409 indivíduos e na área controle (São Bernardo Campo 420 pessoas (sem diferenças significativas quanto a idade e sexo.

O sal coletado nas casas dos examinados apresentava concentração normal de iodo (35,5 + 6,6 mg I/Kg de sal. CONCLUSÕES: A maior prevalência de tireoidite crônica autoimune em ambas as áreas é, provavelmente, decorrente da elevada ingestão nutricional de iodo durante o quinqüênio que precedeu esta pesquisa (1998-2004. A suposta conexão epidemiológica de maior prevalência epidemiológica de TCA com vicinidade com o Polo Petroquímico de Capuava é improvável.

    Full Text Available Discutimos a possibilidade da inserção da Gerontologia na Tabela das Áreas do Conhecimento do CNPq num cenário em essa tabela vem sendo questionada na comunidade científica, particularmente no que se refere à inclusão de áreas multidisciplinares. A partir de Foucault, entendemos a Árvore do Conhecimento como uma taxonomia, um continuum, onde todas as áreas são colocadas lado a lado, mais próximas ou mais afastadas conforme semelhanças e diferenças entre si. Trata-se de um tratamento linear e finito que estabelece que uma determinada área do conhecimento só pode estar situada num ponto da parte da linha que corresponde a uma grande área. A Gerontologia caracteristicamente multidisciplinar não alcançou lugar nessa taxonomia institucionalizada, seja porque haveria problemas em relação a conceitos, interesses e projeto político em sua constituição como área do conhecimento, seja porque a taxonomia seria incompatível com a multidisciplinaridade. Concluímos que é possível conceber uma nova Tabela de Campos de Conhecimentos e de Saberes e proceder visualizações dos estudos sobre o envelhecimento e sobre toda e qualquer região dos conhecimentos e dos saberes na plenitude de sua muldisciplinaridade e de suas transformações ao longo dos tempos.We discuss the possibility of including Gerontology in the CNPq Areas of Knowledge Table, in a scenario where this Table is being questioned by the scientific community, particularly with regard to the inclusion of multidisciplinary areas. Based on Foucault, we view the Tree of Knowledge as taxonomy, a continuum in which all areas are placed side by side, closer together or further apart, depending on their similarities and differences. This finite linear approach establishes that a certain Area of knowledge may be placed only at a point along the line corresponding to a Greater Area. Inherently multidisciplinary, gerontology has not been placed in this institutionalized taxonomy

    To evaluate the efficacy of transcranial direct current stimulation (tDCS) in people with drug-naïve restless legs syndrome (RLS). A two-week, double-blind, randomized, sham-controlled trial was performed. Thirty-three females with RLS were recruited. Participants received five sessions of tDCS using cathodal, anodal or sham stimulation. They were assessed at baseline (T0), three days (T1) and 13 days (T2) after the end of tDCS. Primary outcomes included the International RLS Group Rating Scale (IRLS) and the Clinical Global Impressions-Improvement (CGI-I). Secondary outcomes included the Patient Global Impression scale, the Pittsburgh Sleep Quality Index, the Medical Outcome Study sleep subscales, and the Beck Depression Inventory. Objective neurophysiological changes were assessed using event-related desynchronization/synchronization (ERD/ERS) of electroencephalography. The changes in the IRLS scores, as well as the responder rate in the CGI-I scale, did not differ significantly among the groups. There was also no significant difference in any of the secondary outcome measures and ERD/ERS among the groups. Transcranial direct current stimulation with electrodes on the sensorimotor areas showed no significant effect in people with drug-naïve RLS. Copyright © 2014 Elsevier B.V. All rights reserved.

    This paper discusses the methodology of the implementation of an inventory of vegetation in an urban area using photogrammetric data in the form of color NIR "true - orthophotomap" (true - ortho) and the digital surface model (DSM) created with data from airborne laser scanning, or alternatively, with an automatic correlation of images. The vegetation inventory was conducted by classification on the basis of the characteristics contained in pixels of georeferenced true - ortho while taking into account the elevation data in the form of gridded DSM. To carry out the classification Erdas Imagine software was used. The correct classification process was preceded by the creation of the input data for this task. This data was obtained from the processing of digital aerial photos taken by a Vexcel UltraCam camera with the ground resolution GSD = 10cm and point clouds acquired from ALS. This processing included the generation of digital terrain model in the SCOP++ environment and the digital surface model in an Opals and Inpho environment. The Comparison of DSM created from two different sources of data showed the overall consistency and uniformity and the ability to use both models to generate a true - ortho product from digital aerial photographs. The work was performed on an INPHO photogrammetric workstation. "True - ortho" was generated from both the black and white NIR images and colour images. The classification carried out with the Erdas Imagine software proved that this software is suitable for classification based on the features extracted from the pixels with the simultaneous analysis of elevation data. Simultaneous use of data both from airborne laser scanning and colour infrared images made it possible to make an exact classification of vegetation on very difficult terrain, like built up urban areas.

    All new implementation of activities and equipment needs special attention regarding programming, preparation and operations performance, service and necessary interventions in order to achieve success considering operation, safety and environment. The real challenge in order to realize this change is to guarantee for the costumers the minimum interference, once it is performed on an operational routine basis. The energy distribution area from ArcelorMittal Tubarao (IGC-D) has a very important operational tool to succeed on this task: the operational contingency analysis. The objective of this paper is showing how the operational contingency analysis has been used as a tool to help IGC-D operation on preventing interruptions on supplying the internal costumers as well as keeping the maximum efficiency at the plant.

    The electric energy distribution system dimension together with the involved diverging elements. requires a constant updated information system. The dynamics and the reliability of the information implies in the use of modern technology, as well as data updating and control. There is a constant need of improving the utilities information system and its lack may put into risk not only the quality of the services but also consumer satisfaction. Utilities technical systems should therefore follow this need allowing for a quick response needed in order to keep the system under control and consequently to maintain the quality of the services. This work proposes a basic information technology model for technical areas and for an electric utility that can be applied to manage any data bank at any platform. To have it demonstrated, a Visual Basic application was developed applying X base data structure, which shows the use of alpha numerical data with G S (Geographic Information System). (author)

    The importance of inter-organisational cooperation within the innovation process has been increasingly recognized. In fact, all organisations, at some point, need to look to external sources for inputs to the process of building up technological competence. In this sense, through a detailed case study, this thesis examine theoretical and empirically how collaborative initiatives have supported the Brazilian nuclear regulatory body in the development and implementation of innovations, in order to verify the positive relationship between the collaboration and the organisational innovation performance. Emphasizing the importance of both internal sources of knowledge and external participation, the study encompasses documentary analysis, a preliminary survey and semi-structured interviews with the regulatory body employers in charge of controlling medical and research facilities and activities involving radiation sources. The thesis demonstrates that innovations developed and implemented in the Brazilian nuclear safety and security area are associated with collaborative initiatives, in order to improve the organizational capability to fulfill safety obligations, providing some important implications for regulatory body managers concerned with the management of innovation. The findings also identified actors with a significant degree of influence in the innovation process. The result reveals that the support provided by these actors has a significant influence on the innovation performance of the Brazilian nuclear regulatory body, suggesting that Brazil should adopt more interactive models of innovation and knowledge transfer. In addition, the findings show that these key actors can play a very distinctive role in the context of sectoral systems of innovation information regime. (author)

    In 1975, an agreement between the governments of Brazil and West-Germany was signed for the construction of nuclear power plants in Brazil as well as the extraction, processing and enrichment of uranium. As the result of the first oil crisis and facing the perspective of a continuous world energy crisis, the Brazilian government decided to turn to nuclear power as an alternative supply for the country's energy needs. However, serious limitations were present regarding the transfer of nuclear technology for a third world country. This paper analyzes some aspects of the process involved in the creation of the specialized human resources during the extent of the agreement between Brazil and West Germany. Since its inception, the agreement received harsh criticism from the Brazilian nuclear physics and related fields scientific communities. Because the planning and implementation of the agreement took place during a period of military dictatorship, the decisions relating to the agreement were never debated between the policy makers and the scientific community. Not surprisingly, the agreement received plenty of criticism that ranged from the actual need for nuclear power to technical feasibility and suspicious of possible military uses and even the very policies created to prepare human resources to work in the nuclear area. One of the most important tools of these policies was the Programa de Recursos Humanos para o Setor Nuclear - PRONUCLEAR (Nuclear Sector Human Resources Program), implemented in 1976 and gradually deactivated starting in 1983.

    This study reviews the geological characteristics and puts forward a new evolution model for the Araxa Group in its type-area, the southern segment of the Neo proterozoic Brasilia Belt, Minas Gerais, Brazil. The Araxa Group is confined within a thrust sheet belonging to a syn formal regional fold, the Araxa Syn form, overlying two other thrust sheets made of the Ibia and Canastra Groups. The Araxa Group is described as a tectono stratigraphic terrane in the sense of Howell (1993). It comprises an igneous mafic sequence, with fine and coarse grained amphibolites, associated with pelitic meta sedimentary rocks, and subordinate psanmites. All rocks were metamorphosed to amphibolite facies at ca. 630 Ma ago and were intruded by collisional granites. The amphibolites represent original basaltic and gabbroic rocks, with minor ultramafic (serpentinite/ amphibole-talc schist). The basalts are similar to high Fe O tholeiites, with REE signatures that resemble E-MORB and {epsilon}{sub Nd(T)} =+ 1.1. The meta sedimentary rocks are interpreted as the result of a marine deep-water sedimentation. They have Sm-Nd model ages of 1,9 Ga, and {epsilon}{sub Nd(T)} = -10.21. The amphibolites and metasediments could represent a fragment of back-arc oceanic crust. The data presented here differ significantly from the original definition of Barbosa et al. (1970) who describe the Araxa Group as a pelitic/psanmitic sequence and the collisional granites as a basement complex. (author)

    The development of new urban areas and the necessity of disposing of goods production and increased movement of people requires the intervention of man in areas previously not inhabited or preserved of the human interference. Infrastructural work sites have direct effects on ecosystems and RS/486 causes, beyond the visual impact on the landscape, a strong fragmentation in Atlantic forest. The removal of vegetation around the highway can facilitate the occurrence of natural disasters related to changes in geomorphology and weathering processes may result erosion and soil accommodation. To study the vulnerability and susceptibility the mass movements of the sub-watershed Três Forquilhas river along the highway RS 486 were employed techniques of GIS and remote sensing to produce maps of environmental vulnerability from employment of such variables as land use, geomorphology, geology, digital elevation model (DEM, slope and normalized digital vegetation index (NDVI by applying analytic hierarchy process method (AHP to support decision. The resulting maps matchie the purpose of defining priority areas for action of the Rio Grande do Sul State Civil Defense.

Baixas coberturas vacinais e quase ausência de atividades de vigilância, traduzida pelo não-envio sistemático de amostras para exames laboratoriais nos anos imediatamente anteriores a 1995, foram os fatores determinantes do aparecimento da epizootia. Este evento ilustra os riscos de se negligenciar a profilaxia permanente da raiva, mesmo numa cidade com razoável estrutura dos serviços de saúde e localizada numa das áreas de maior desenvolvimento econômico do País.This report describes some epidemiological aspects of a rabies epizootic that started in 1995 in the urban area of Ribeirão Preto, SP, Brazil, and discusses its main causes. All laboratory confirmed cases were described according to a set of epidemiological variables. Simultaneously, information was raised concerning rabies vaccine coverage and epidemiological surveillance activities. In addition to one human case, 58 rabid animals were confirmed in 1995 (54 dogs, 3 cats. and 1 bat. There were 20 cases in 1996 (18 dogs and 2 cats. Geographical distribution was uneven in the city, with higher concentrations observed in the Western, Northern, and Southwestern sections, corresponding to the poorest areas. No seasonal

    Full Text Available Arachnids make up an exclusive predator group. Eating habit makes the arthropods to move around in search for hunting or building traps with silk threads. In order to know the araneofauna of the Godoy’s Forest State Park, pitfall-like traps were installed inside the forest, edge and adjacent area predominantly grassy. Collections were carried out fortnightly, in the period of a year, separating what was collected during the day and during the night. One hundred and twenty-one individuals were collected, belonging to 18 families where Lycosidae and Theridiidae were the most abundant, although Lyniphiidae family has prevailed in the forest area. Young individuals prevailed. It is concluded that the highest frequency and abundance of young individuals may be directly related to its dispersal and spiders belonging to the Lycosidae, Zoridae and Theridiidae families, being able to be used as bioindicators. Os aracnídeos compõem um grupo exclusivamente predador. O hábito alimentar faz com que o artropoda locomova-se em busca da caça ou construa armadilhas com fios de seda. Buscando conhecer a araneofauna do Parque Estadual Mata dos Godoy, foram instaladas armadilhas tipo ptiffal dentro da mata, borda e área adjacente, com vegetação predominantemente formada por gramíneas. As coletas eram realizadas quinzenalmente, no período de um ano, separando o coletado em diurno e noturno. Foram coletados 121 indivíduos, pertencentes a 18 famílias, das quais as famílias Lycosidae e Theridiidae foram as mais abundantes, embora a família Lyniphiidae tenha predominado na área de mata. Houve maior freqüência de indivíduos jovens. Conclui-se que a maior freqüência e abundância de indivíduos jovens pode estar diretamente relacionada a sua dispersão e, além disso, as aranhas pertencentes as famílias Lycosidae, Zoridae e Theridiidae, podem ser utilizadas como bioindicadores.

    This paper shows a thoroughly analysis of a biodiesel production model tailored to insert in the production chain communities near fossil fuels fired power plants located in the northeast Brazilian semi-arid. Such insertion would be conduced by the replacement of diesel by a diesel-bio diesel mixture, the last produced by local families. Among the factors analyzed on this small scale bio diesel production chain are: the castor oil extraction, transesterification process, efficiency and adequacy in power plants. The aim is to turn thermal power plants into a sustainable development vector, considering social, economical and environmental aspects such as local employment and income boost, settlement increase on rural areas, decrease of green house gases emissions, clean energy production and so forth.

  8. The effect of Na vapor on the Na content of chondrules

    Chondrules contain higher concentrations of volatiles (Na) than expected for melt droplets in the solar nebula. Recent studies have proposed that chondrules may have formed under non-canonical nebular conditions such as in particle/gas-rich clumps. Such chondrule formation areas may have contained significant Na vapor. To test the hypothesis of whether a Na-rich vapor would minimize Na volatilization reaction rates in a chondrule analog and maintain the Na value of the melt, experiments were designed where a Na-rich vapor could be maintained around the sample. A starting material with a melting point lower that typical chondrules was required to keep the logistics of working with Na volatilization from NaCl within the realm of feasibility. The Knippa basalt, a MgO-rich alkali olivine basalt with a melting temperature of 1325 +/- 5 C and a Na2O content of 3.05 wt%, was used as the chondrule analog. Experiments were conducted in a 1 atm, gas-mixing furnace with the fO2 controlled by a CO/CO2 gas mixture and fixed at the I-W buffer curve. To determine the extent of Na loss from the sample, initial experiments were conducted at high temperatures (1300 C - 1350 C) for duration of up to 72 h without a Na-rich vapor present. Almost all (up to 98%) Na was volatilized in runs of 72 h. Subsequent trials were conducted at 1330 C for 16 h in the presence of a Na-rich vapor, supplied by a NaCl-filled crucible placed in the bottom of the furnace. Succeeding Knudsen cell weight-loss mass-spectrometry analysis of NaCl determined the P(sub Na) for these experimental conditions to be in the 10(exp -6) atm range. This value is considered high for nebula conditions but is still plausible for non-canonical environments. In these trials the Na2O content of the glass was maintained or in some cases increased; Na2O values ranged from 2.62% wt to 4.37% wt. The Na content of chondrules may be controlled by the Na vapor pressure in the chondrule formation region. Most heating events capable

Este estudo teve como objetivo a análise das interações entre as flores de Vochysia lucida e seus visitantes florais, em uma área de restinga no Estado da Bahia, Brasil. V. lucida é uma espécie arbórea e apresenta inflorescências do tipo racemo, com cerca de 100 a 170 flores. As flores são zigomorfas, amarelas e foram consideradas melitófilas. O néctar floral é produzido e estocado em esporão, localizado no cálice. O pico de floração de V. lucida ocorreu em novembro e dezembro. Durante o estudo as flores abriam às 6:00 h, quando o estigma já estava receptivo. Na abertura da flor a antera já não estava mais presente e os grãos de pólen estavam depositados na parede do estilete, ocorrendo apresentação secundária de pólen. As pétalas caíam no final da tarde, por volta das 17:00 h. Os beija-flores embora freqüentes nas flores de V. lucida foram considerados visitantes oportunistas. Entre os visitantes florais registrados, as abelhas de grande porte foram consideradas os polinizadores mais eficientes, especialmente Xylocopa frontalis, por ter morfologia e comportamento adequados para contatar as estruturas reprodutivas da flor, durante as coletas de néctar, e por sua elevada freqüência de visita.Vochysia species are Neotropical and present flowers that can be visited by bees, hummingbirds, and butterflies.

    Water and energy are the physic factor, which are most influential on the life conditions in the semi-arid rural environment as a whole and in the agriculture production systems in particular. Water is a resource, which - even though not rare - is found in limited quantities and not always is available on the ground surface, meaning that it should be retrieved through either proper wells or deep holes excavated into ground. Therefore, its use should be optimized. In the rural environment to turn water into an available resource in a sufficient amount in order to improve the population life conditions is still a challenge. In the rural semi-arid regions the electric energy distribution is small compared to the other regions of the country. Nevertheless the geographic position of the Brazilian Northeast - close to the equator - adds to this region high levels of insolation - something close to 3,000 hours of sunshine per year - turning this energy resource into a very abundant one. It is known that the use of solar energy, among the use of other resources, has increased the most worldwide in the last decade. The use of photovoltaic cells has increased around 17% per year in the 90's. In the last years several applications, which had the sun as their electric energy resource, were implemented in the rural areas of many countries. The Brazilian Northeast region was the preferred target of programs and projects aiming at the dissemination of the photovoltaic solar technology. Water pumping is one among the most noble applications of the photovoltaic solar technology. There are many pumping systems configurations for either deep or shallow wells, which use either superficial, immerse or floating motor-pumps, which in turn can be driven by either continuum or alternate current. In this work the usage of water pumped with solar energy from Amazon wells (also called 'cacimboes') for small family-based areas of localized irrigation (less than 1 ha), whose main

    Full Text Available Este trabalho tem como objetivo analisar o papel das políticas de ocupação e o uso dos recursos naturais da Amazônia e identificar em que medida essas políticas podem afetar o comportamento de determinados grupos em relação ao desflorestamento da região. Para tanto, apresenta os conceitos de capital social, ação coletiva, governança e governabilidade utilizados para tentar explicar o comportamento de alguns atores presentes na área de influência da rodovia BR-163 (Cuiabá-Santarém. Os resultados alcançados indicam que as políticas de controle do desflorestamento somente conseguirão influenciar o comportamento dos atores da região se houver uma ação mais efetiva do Estado, por meio da utilização de mecanismos de regulamentação. Essa ação deve levar em conta as relações de poder local e o reflexo delas sobre as taxas de desflorestamento. Finalmente, fica claro que o estabelecimento de instrumentos e incentivos econômicos capazes de interferir em comportamentos eminentemente individuais também deve ser parte de uma política de desenvolvimento regional.The text analyzes settlement policies and land use processes in the Brazilian Amazon rain forest region and their relation with the evolution of regional deforestation rates. For that purpose, the concepts of social capital, collective action and governance were used to explain practices and activities carried out by selected actors present in the area of influence of the BR-163 highway (Cuiabá-Santarém. Results indicate that the success of these policies depends on the State's effective presence in the region, by means of the deployment of regulatory instruments. Also, these actions have to consider local power relationships and how they reflect themselves in Amazon deforestation rates. Finally, it is shown that the establishment of economic mechanisms and incentives could contribute to changing actors' individual behavior.

A partir do estudo desenvolvido por Moretti e Campanário (2009, o qual mapeou as principais referências bibliográficas utilizadas para fundamentar os trabalhos apresentados sobre a temática nos Encontros Nacionais da Anpad, foram selecionadas oito obras referenciadas, as quais estavam relacionadas especificamente aos fundamentos da responsabilidade social e analisaram-se os trechos que tratam dos motivos pelos quais as empresas praticam ações de responsabilidade social. Posteriormente, as obras foram analisadas sob a ótica das principais correntes epistemológicas do séc. XX, consideradas relevantes para a compreensão do fenômeno: empirismo, racionalismo, utilitarismo, positivismo, funcionalismo e dialética. As conclusões apontam para o fato de que, além da existência de uma zona de conforto intelectual nos estudos sobre o assunto, já apontadas por Moretti e Campanário (2009, o embasamento das referências utilizadas está centrado na lógica de operar do paradigma dominante nas ciências da administração, ressaltando o caráter funcionalista e utilitarista das práticas de responsabilidade social por parte das empresas. Curiosamente, os estudos não puderam ser classificados como empiristas, racionalistas ou positivistas devido à falta de dados concretos que fundamentassem as conclusões dos autores, com exceção da obra de Freeman (1999 a qual apresenta bases empíricas a partir das quais as conclusões são auferidas. As conclusões chamam a atenção para as dificuldades de desenvolvimento de um campo de pesquisas centrado em poucas obras

As principais moléstias transmissíveis na mortalidade infantil foram em ordem decrescente: Sarampo, Coqueluche, Tétano, Tuberculose, Disenteria, Infecções meningocócicas, Varíola e Encefalite. Entre os principais fatôres predisponentes, assinalou-se: precária assistência materno-infantil, carência de leitos gratuitos em maternidade, alta proporção de nascimentos domiciliares, falta de pessoal especializado para atendimento infantil, inadequadas condições de saneamento (40% da população sem rêde pública de água e 65% sem rêde de esgôto, deficit de leitos hospitalares infantis para a população de menor poder aquisitivo e, sobretudo, baixo nível sócio-econômico de uma boa parcela da população em estudo.Health levels were studied through a historical series in the Metropolitan Area of S. Paulo (Brazil, composed of 37 cities with a population of 8 millions inhabitants. Analysis made by region and cities seemed limited, since the vital statistical data are recorded through the local occurrence and not through the local origin. For this, superestimation of rates can happen exactly in the areas where the health resources are more available like the city of S. Paulo, which works as a polorizing center of medical care. The fall of crude death rate in the last eight years was low, changing from 8.53 to 7.67 deaths per thousand inhabitants. Nelson de Moraes' Curve

Com isso, cada vez mais o relevo e os rios são cobertos pelas edificações. Neste contexto, falar de áreas de preservação permanente nas cidades correlacionando-as com as políticas públicas que gerenciam e gestam as cidades, bem como o processo de produção e reprodução do espaço urbano é algo complexo, pois envolve muitos interesses, principalmente dos agentes que o produzem. Neste contexto o trabalho visa discutir as condições socioambientais das áreas de preservação permanente na cidade. As áreas de preservação permanente são preocupações da temática ambiental relacionadas à sociedade e ao ambiente. Preservá-las é uma preocupação social, que envolve a discussão de conceitos como a natureza, preservação, e qualidade de vida no meio ambiente urbano. Através de imagens de satélite, fotografias aéreas e dados coletados, diretamente no campo, buscamos localizar e espacializar as informações, de forma a obter uma visão de conjunto da distribuição do curso hídrico estudado, juntamente com as condições das áreas ao seu em torno que, a priori, deveriam ser destinadas à preservação permanente. Em Guarapuava, há uma importante rede de drenagem, contudo, os rios urbanos estão praticamente todos canalizados, e aqueles que ainda preservam seu curso original, estão degradados pelo lançamento de esgoto e assoreamento. Pensar condições e formas de planejamento e de gestão pública voltados para a conservação dessas áreas que a priori seriam de preservação, é um caminho para a recuperação dos cursos hídricos que ainda resistem à expansão da cidade.

    The energy demand of any particular city depends, upon others, on its urbanization process as a direct function of the accessibility parameter. The 'heat islands' are directly related to deforestation and verticalization, being Sao Paulo a major example of a urban process leading to desertification of entire surrounding macro-metropolis, with climate changings and resulting increase in the end-uses energy demand. The interface between efficiency on transport system, energy end-uses efficiency and environmental sustainability provide guidelines to the deployment of a sustainable consumer demand pattern.

Foi conduzido estudo epidemiológico, seguindo o delineamento quase-experimental, com 664 crianças, sendo 332 moradoras de residência que têm cisterna e 332 que utilizam água de outra fonte. A variável dependente foi a ocorrência de diarreia nas últimas 72 horas; as outras informações foram obtidas por meio da aplicação de questionários estruturados. A prevalência total de diarreia foi de 5%, porém sem diferença significativa entre os grupos. As variáveis que explicaram a morbidade foram o grupo, a idade da criança, a ingestão de vitamina ou fortificante, e o local de descarte das fraldas sujas com fezes da criança. Não houve diferença significativa entre os grupos na avaliação da qualidade microbiológica da água, ou seja, o uso de água de chuva pode não ter proporcionado melhorias no acesso à água de melhor qualidade quando comparado com as outras fontes utilizadas. No entanto, há que se considerar falhas nos cuidados, no manuseio e no tratamento da água adotados. Destaca-se a necessidade de melhoria das práticas sanitárias da população do meio rural para que a higiene pessoal, domiciliar e em relação à água consumida sejam incorporadas como hábitos rotineiros.The present text evaluated the diarrhea prevalence in children under 60 months, according to water supply.

    Ouabain, a specific inhibitor of the Na(+)/K(+)-pump, has previously been shown to interfere with intercellular communication. Here we test the hypothesis that the communication between vascular smooth muscle cells is regulated through an interaction between the Na(+)/K(+)-pump and the Na(+)/Ca(2+)-exchanger leading to an increase in the intracellular calcium concentration ([Ca(2+)](i)) in discrete areas near the plasma membrane. [Ca(2+)](i) in smooth muscle cells was imaged in cultured rat aortic smooth muscle cell pairs (A7r5) and in rat mesenteric small artery segments simultaneously with force. In A7r5 coupling between cells was estimated by measuring membrane capacitance. Smooth muscle cells were uncoupled when the Na(+)/K(+)-pump was inhibited either by a low concentration of ouabain, which also caused a localized increase of [Ca(2+)](i) near the membrane, or by ATP depletion. Reduction of Na(+)/K(+)-pump activity by removal of extracellular potassium ([K(+)](o)) also uncoupled cells, but only after inhibition of K(ATP) channels. Inhibition of the Na(+)/Ca(2+)-exchange activity by SEA0400 or by a reduction of the equilibrium potential (making it more negative) also uncoupled the cells. Depletion of intracellular Na(+) and clamping of [Ca(2+)](i) at low concentrations prevented the uncoupling. The experiments suggest that the Na(+)/K(+)-pump may affect gap junction conductivity via localized changes in [Ca(2+)](i) through modulation of Na(+)/Ca(2+)-exchanger activity.

    The core of acai comes from a palm tree native to the Amazon, which grows in clumps. It is composed of several stems, reaching to form up to 25 feet in each clump. From Its fruits is obtained a drink (juice) and consumed daily by people in the Para state, especially the capital Belem and riverside communities. The state of Para is the largest producer of acai with 112,676 tons/year of fruit. Of this total 93.521 tons/year is residue (seed), or approximately 83 %. The community of Maroon that lives on the margin of the Genipauba River, in Abaetetuba, in Para state, has no electricity and is a major producer of acai, which is traded during the season 'in natura'. This paper presents the sustainable use of seeds, a byproduct of processing the fruits of acai. With appropriate methodology, natural pellets were obtained without compression, the acai biofuels. The work presents the technological innovation that has this type of pellet. The calorific value of the core, obtained in the laboratory, was in medium 4.505 kcal/kg and the average potential energy around 40.800 MWh/month. The pellets have great potential for export due to their use. It can be used in gasifiers, boilers for power generation, mechanical and gas ovens at bakeries, biomass stoves, replacing old coal irons, etc..

    Full Text Available The goal of this study was to stratify priority areas for malaria control in the State of Mato Grosso, Brazil, based on spatial analysis. The variables used were: Annual Parasite Index (API, Plasmodium falciparum/Plasmodium vivax ratio, population variation, number of families settled, and percent of deforested area. The Moran's I and Local Moran Test were applied, visualized with the Box Map and Moran Map, for 1986- 1991, 1992-1997, and 1998-2003. Box Map identified areas with high, low, and intermediate priority for control, and Moran Map identified municipalities with significant autocorrelation. In the high priority area, located in the North of Mato Grosso, malaria incidence decreased drastically despite the increase in the number of municipalities from the first to the last period. Other municipalities were added to the lower priority area, from the Southeast, Southwest, and Central-South of the State. The intermediate priority area was located along the border with neighboring States and municipalities classified as high and low priority. Spatial analysis showed the importance of the neighboring phenomenon between municipalities in defining priority areas, thus highlighting the technique's advantages for use in malaria control and surveillance.Pautado em técnicas de análise espacial, analisou-se a estratificação de áreas prioritárias para controle da malária no Estado de Mato Grosso, Brasil.

    Rio de Janeiro Petrochemical Complex (COMPERJ) will be installed in the north region of Itaborai city. The start of COMPERJ operations is foreseen to 2012. Because of the intensification of industrialization and urbanization processes, the implantation of COMPERJ will bring environmental modifications for Itaborai city and neighbors areas. Thus, meteorological and air quality monitoring was initiated in February of 2007 with the intention of carrying out a characterization of air pollution in this area, before COMPERJ operations. In this work are presented the results found in campaigns performed of February of 2007 until April of 2008. The meteorological monitoring disclosed that the meteorological parameters have varied enough throughout the months, but these are representative of a global behavior of the studied area. Monitoring of air quality has shown that atmospheric levels of monitored pollutants has been generally below of Brazilian air quality standards. This fact corroborates the basic aspect of the present study: identification of the concentrations 'background' in the studied area. Throughout the period of monitoring, the primary air quality standard for ozone has been reached. Observations of meteorological parameters indicate that this fact is associated to the emissions originated from Sao Goncalo, Niteroi and Rio de Janeiro cities. (author)

As a result of the study it can be seen that for the city of Piracicaba the collecting area of 4.62 M{sup 2} presents solar fraction varying between 87.27% and 97.79% for heating 300 liters of water and 200 liters of water daily, respectively. Based on the results one can conclude that the savings would be about 47.74 GWh, if a collection area of 360 thousand m{sup 2} (0.36 km{sup 2}) were fully exploited, which represents savings of approximately R$ 15.86 million per year for the municipality.

    In KALIMER-600, a sodium-cooled fast reactor designed by KAERI, thermal energy is transported from high-temperature liquid Na (526 .deg. C at 0.1 MPa) to low temperature water (230 .deg. C at - 19.5 MPa) through a heat exchanger. If any leakage or rupture occurs during the operation of this heat exchanger, highly pressurized liquid water can penetrate into the liquid Na channels; this contact should instantly cause SWR. As reaction continues, liquid water is soon vaporized by pressure drop and huge amount of reaction heat. This generated water vapor expands large reaction area and increases sodium-water vapor reaction process. Therefore, the rapid generation of reaction product (like H{sub 2}) and water vapor increases the system pressure that can cause the system failure in SFR. To reduce this strong chemical reaction phenomena between Na and water, some we have focused on suppressing the chemical reactivity of liquid Na by dispersing nanoparticles (NPs). For the real application of NaTiNF, the pressure change induced by NaTiNF-water reaction is compared with Na-water reaction in the present study. NaTiNF contains 100nm of Ti NPs at 0.2 vol. %. The reaction rate of NaTiNF-water reaction is also investigated as reaction temperature increases. Sodium-water vapor reaction (SVR) will occur when an SWR accident occurs in SFR. In this manner, NaTiNF-water vapor reaction is experimentally performed for ensuring the suppression of chemical reactivity of NaTiNF in contact with water vapor. In the basic step for reducing risk of an SWR in SFR, we have experimentally verified the suppressed chemical reactivity of liquid sodium using Ti NPs through SWR and SVR experiments. In SWR, Na based titanium nanofluid (NaTiNF) shows lower pressure change than Na. As T{sub R} increases, P{sub max} in Na-water reaction increases while NaTiNF does not. The reaction rate of NaTiNF shows twice slower than that of Na. In SVR, NaTiNF shows slower temperature increase than Na. The distinct

Este consiste em uma ferramenta de grande utilidade para a descrição de características da população e para a identificação de grupos de risco. Considerando a afasia uma desintegração da linguagem, é necessário compreender as dissociações e comprometimentos pertinentes. OBJETIVO: analisar estudos epidemiológicos de caráter transversal que focam alterações em pacientes afásicos adultos para investigação das suas principais manifestações. CONCLUSÃO: estudos transversais mostram meios de buscar compreender como esta modificação de saúde abrange os sinais e sintomas relacionados. Considerando que a linguagem por ser um meio de comunicação privilegiado, para o afásico, a perda desse instrumento torna-se uma fonte de isolamento e de solidão. Assim, a identificação de indivíduos portadores de afasia pode contribuir ao diagnóstico preciso, corroborando a compreensão dos achados fonoaudiológicos em linguagem e no auxílio à reabilitação. Porém, estas evidências científicas deverão ser efetivadas em conjunto aos estudos longitudinais para dar suporte à criação de novas técnicas e estratégias de recuperação para os lesionados cerebrais favorecendo a melhora da comunicação e consequente interatividade.BACKGROUND: one of the most widely delineations used in epidemiological research is the cross-sectional study.

    Zeolites Na-A and Na-X are important synthetic zeolites widely used for separation and adsorption in industry. It is of great significance to develop energy-efficient routines that can synthesize zeolites Na-A and Na-X from low-cost raw materials. Coal fly ash (CFA) is the major residue from the combustion of coal and biomass containing more than 85% SiO2 and Al2O3, which can readily replace the conventionally used sodium silicate and aluminate for zeolite synthesis. We used Na2CO3 to replace the expensive NaOH used for the calcination of CFA and showed that tablet compression can enhance the contact with Na2CO3 for the activation of CFA through calcination for the synthesis of zeolites Na-A and Na-X under mild conditions. We optimized the control variables for zeolite synthesis and showed that phase-pure zeolite Na-A can be synthesized with CFA at reactant molar ratio, hydrothermal reaction temperature and reaction time of 1.3Na2O: 0.6Al2O3: 1SiO2: 38H2O at 80°C for 6 h, respectively, while phase-pure zeolite Na-X can be synthesized at 2.2Na2O: 0.2Al2O3: 1SiO2: 88H2O at 100°C for 8 h, respectively. The composition, morphology, specific surface area, vibration spectrum and thermogravimetry of synthesized Na-A and Na-X were further characterized.

    Na-A and/or Na-X zeolite/porous carbon composites were prepared under hydrothermal conditions by NaOH dissolution of silica first from carbonized rice husk followed by addition of NaAlO 2 and in situ crystallization of zeolites i.e., using a two-step process. When a one-step process was used, both Na-A and Na-X zeolites crystallized on the surface of carbon. Na-A or Na-X zeolite crystals were prepared on the porous carbonized rice husk at 90 deg. C for 2-6 h by changing the SiO 2 /Al 2 O 3 , H 2 O/Na 2 O and Na 2 O/SiO 2 molar ratios of precursors in the two-step process. The surface area and NH 4 + -cation exchange capacity (CEC) of Na-A zeolite/porous carbon were found to be 171 m 2 /g and 506 meq/100 g, respectively, while those of Na-X zeolite/porous carbon composites were 676 m 2 /g and 317 meq/100 g, respectively. Na-A and Na-X zeolites are well-known microporous and hydrophilic materials while carbonized rice husk was found to be mesoporous (pores of ∼3.9 nm) and hydrophobic. These hybrid microporous-mesoporous and hydrophilic-hydrophobic composites are expected to be useful for decontamination of metal cations as well as organic contaminants simultaneously. - Graphical Abstract: Novel Na-X zeolite/porous carbon composite.

    Full Text Available A hipótese da existência de uma relação linear entre o alcance de canhões hidráulicos e a velocidade do vento, descrita no modelo de Richards & Weatherhead e amplamente utilizada na simulação da distribuição de água de canhões hidráulicos em condições de vento, foi avaliada neste trabalho para aspersores de tamanho médio. Na avaliação foram consideradas distâncias de alcance entre os aspersores modelos Agropolo/NY e Naan/5024 e os limites de sua área molhada, observadas em ensaios de campo, medidos nas direções: contrária, a favor e perpendicular ao vento. As retas ajustadas pelo método dos mínimos quadrados indicaram, em relação ao alcance do aspersor quando da ausência de vento, que para cada incremento de 1 m s-1 na velocidade do vento ocorreram: (i um decréscimo de 3,7% na direção contrária ao vento; (ii um decréscimo de 3,0% na direção perpendicular ao vento e (iii um acréscimo de 2,2% na mesma direção do vento, indicando que no intervalo de velocidades de vento consideradas (0 a 3 m s-1 a hipótese de uma relação linear entre o alcance de aspersores de tamanho médio e a velocidade do vento, foi mantida.The hypothesis of a linear relationship between wetted radius of gun sprinklers and wind velocity, as proposed by the Richards & Weatherhead model and widely used for simulation of water distribution by gun sprinklers under windy conditions, was evaluated in this study for medium-sized sprinklers. Distances from the sprinkler models used in this study (Agropolo/NY e Naan/5024 to the limit of the wetted area were determined through various field tests for upwind, downwind and crosswind conditions. Using the least square method it was found that, in relation to the no-wind radius, for each 1 m s-1 increase in wind velocity there was: (i a distance reduction of 3.7% for upwind edge; (ii a 3.0% decrease in distance for crosswind edge; and (iii a 2.2% increase in distance for downwind edge.

    Full Text Available Hortaliças in natura, comercializadas na região metropolitana de São Paulo, SP (Brasil, foram analisadas através de metodologia própria, visando à pesquisa e à identificação de formas de transmissão de helmintos intestinais de interesse médico. As hortaliças examinadas, constituídas de 50 amostras de cada variedade, foram de: alface (Lactuca sativa, variedades lisa e crespa, escarola (Chichorium sp e agrião (Nasturtium officinale. Os resultados evidenciaram elevados percentuais de contaminação em todas as variedades analisadas, porém, as freqüências de helmintos foram maiores no agrião. A escarola apresentou valores médios, geralmente situados entre as alfaces e o agrião. Os números médios de ovos e larvas por 100 gramas de amostra, embora elevados, não apresentaram diferenças estatisticamente significantes entre as quatro variedades de hortaliças estudadas. Uma grande variedade de helmintos, de ocorrência freqüente na população residente na Região Metropolitana de São Paulo, foi observada nas amostras. Os mais freqüentes, no entanto, foram: ancilostomídeos e Ascaris sp. Recuperaram-se também ovos de Toxocara sp, Fasciola sp e de tricostrongilídeos, comprovando a ocorrência de contaminação das hortaliças por fezes de animais domésticos. Considerando-se os resultados obtidos, ressalta-se a importância das hortaliças na transmissão de helmintíases intestinais, bem como a necessidade de medidas que propiciem uma melhoria na qualidade higiênico-sanitária destes alimentos.Vegetables in natura, commercially traded in the metropolitan area of S.

    A sectional study was conducted on workers in 137 laboratories, 30 pilot units and support areas of a research center in order to evaluate the level of occupational exposure based on environmental measurements from the 2004's workplace environmental protection program with the aim of assessing the risk of health injury arising from occupational exposure to chemical agents. The recognition task was developed using interviews and secondary data from safety programs covering health and environmental risks of all procedures, facilities / equipment and activities. 2,738 cases of exposure were identified, involving exposure to 484 chemicals (with 246 agents and 238 chemicals mixtures), ranging in purity and concentration, found in 243 jobs. The target population comprised 1,563 workers exposed to chemical agents, subdivided into 168 different Homogeneous Group of Expose with an average of 4.55 employees per group. In each workplace were identified, on average, 4.91 HGE and, on average, 3.73 chemicals. Regarding the 2,738 cases of chemical agents versus activity, in 14% of the cases (382 cases) there was daily exposure, in 82.1% (2,249 cases) the frequency of use varied from two to three times a week and in the remaining 3.9% (107 cases) the use was sporadic, about once a week or less. Nine of the ten most frequently used substances were hydrocarbons. 977 samples (485 samples of chemicals and 492 samples of benzene) were measured. Out of the total number of measurements taken, 91.9% of the evaluations corresponding to 92.5% of workers who work with chemicals, presented environmental measurement results below the action level, demonstrating, therefore, exposure to low concentrations.Chemical were found in most areas of work and accounts for 81% of occupational exposure in the evaluated laboratories. There is evidence of presence of one given substance in various locations, as well as of a great diversity of frequently used chemicals, since in every workplace 3

    During the last years the need for the increase in the electricity energy production as much as in Brazil as in the rest of the world, has raised the tone o the debate about the environmental impacts as a result of these debates, the government and the Non-Governmental Organizations (NGO's) have requested several opinion researches aiming at measuring and evaluating the knowledge and perception of the public in relation to the best non-polluting energy sources. Prior to 2001 these researches would not make any sense in Brazil as the majority of its power grid is made of hydroelectric plants, a renewable energy source. However, when in that year it occurred a drought, the competent authorities have faced the necessity of developing a plan, the National Energy Plan (PNE2030) which recommends, among other objectives, finalizing the construction of the Angra 3 plant and the implementation Df new nuclear plants in places still to be determined. Even considering the complexity of the subject, this paper presents a field research realized from September 28th, 2010 to October 28th, 2010 of the current level of perception of the Brazilian population, specifically the residents of three cities of Rio de Janeiro, about the nuclear area. As a result of this work, it is suggested how the competent authorities should proceed to reach in an efficient manner, by means of communication campaigns both informative and educational, a greater understanding of the population about the proposed subject.

    The municipality of Monte Alegre, located in the Amazonian State of Para, Brazil, presents scattered areas with increased levels of natural radiation due to uranium rocks. The objectives of this dissertation were: to evaluate the mortality trend among Monte Alegre residents, and to compare it with that observed in neighbor municipalities (Alenquer and Prainha) without natural radiation sources; and to determine the impact of cancer distribution either in Monte Alegre or control counties population, taking into account their estimates of cancer incidence and mortality. The dissertation was organized in two papers. The first one aimed to evaluate the mortality trend for all causes of death, cancer, and unknown causes of death occurred between 1981-2005. Analyzed data was provided by the Brazilian National Mortality Information System (SIM), being the general population of the State of Para used as reference. In the second paper, cancer mortality risks at selected sites were ascertained using standardized mortality ratios (SMR) and mortality odds ratios (MOR). Additionally, cancer mortality risk ratios of Monte Alegre and control counties were obtained towards the ratio between SMRs of selected cancer sites in both areas. Three different sources of data were used to retrieve all cancer cases in the studied area, and therefore, to estimate cancer incidence in the studied populations: the diagnosed cancer cases at the regional reference centers for oncological care settled in Santarem, Belem and Manaus; the cancer-related hospitalization authorization records obtained at the Brazilian National Health System (SUS) registries; and primary data of cancer reported by local residents at a population-based health survey conducted by our research team in 2007-2008. A declining trend for all causes of death mortality in Monte Alegre general population, as well as for the unknown causes of death, was observed along the studied time series for both gender.

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

The paper presents a theoretical background on issues pertaining to production and environmental impacts of waste and the legislation that regulates on the subject. The study in question had an exploratory-descriptive. For data collection, 100 questionnaires were applied, they developed based on theoretical assumptions about the subject of study. To assess and meet the waste collection program in rural areas existing in the municipality conducted a documentary analysis using as source the Master Plan of the municipality (2009. The results showed that the majority of household waste produced in the rural area of research, does not receive the correct destination, according to basic rules to prevent environmental pollution. It was also found that the majority of people surveyed do not receive guidance on how to appropriate treatment to be given to the waste produced and also no incentive for such actions. As for the waste collection program, this does not seem to be efficient, because it was evident that the program does not meet most of the communities in rural areas. According to the opinion of the program users did not have a good rating, because 55.8% of users indicated that the program is poor and fair.DOI: 10.5902/198346597657O presente estudo teve como objetivo identificar o destino dado aos resíduos domésticos produzidos na zona rural e também avalizar o programa de coleta desses resíduos no município de Pranchita - PR.

    The aim of the study is to assess the compliance rate of treatment of postpartum hemorrhage (PPH) according to guidelines developed by the CNGOF within our network by a first audit, and evaluate the impact of this first audit by conducting a second audit. An initial audit of resources and management of postpartum hemorrhage (PPH) was conducted in 2006-2008 in 24 maternity hospitals of the Pays-de-la-Loire. The audit had identified six areas for improvement. A second audit was implemented in 2009-2010 to evaluate the actions of prevention and measure changes in the management of PPH. Two interns have distributed the 24 maternity homes and moved in each hospital to see 10 cases of vaginal delivery (VD) (section "Prevention"), and the last cases of PPH following a VD. The results are in compliance rate compared to the repository of the HAS in 2004. The first audit was conducted on 101 PPH in total. It has allowed us to propose corrective actions to the 24 maternity hospitals: leaf specific monitoring, reporting amounts of blood loss, transfusion on these clinical criteria without waiting for the blood cell counts, indicating more frequent and rapid sulprostone, set for maternity hospitals without surgical skill an agreement with a visceral surgery department, and avoid maternal transfers for PPH. For the second audit, the compliance rate of the preventive aspect was 73% (95: 71-75%) of 239 cases of BA with variations according to maternity from 48 to 93%. Compliance rates according to the criteria were: 99% obstetric consultations, 98% for anesthesia, 92% for hemoglobin, 77% for the group card available in the record, 89% agglutinins, 35% for the notification of the installation of bag, 36% for the notification of the amount of blood lost, 69% for the supervisor within two hours, and 64% for the directed delivery.

    The Continental Shelf of the Cabo Frio Area shows unique features in its tectono-sedimentary evolution when compared to the other areas of the Campos and Santos basins. The presence of a regular pattern of antithetic faults in the basement and in the sin-rift and post-rift sedimentary sections, are some of these features. In addition, the area shows important magmatic events in the Upper Cretaceous and Tertiary sequences, which climax took place in the earliest portion of the Middle Eocene. The description of these magmatic events and their influence in the post-rift sedimentation is the main objective of this paper. The analyses of seismic reflection and well log data, in the work area, points to a set of diagnostic features that can lead to the identification of magmatic events and the distinction of intrusive from extrusive rocks, as well as their intercalations with epiclastic sedimentary sequences. Volcanic edifices have preserved their conical shapes when they were formed under submarine conditions; under subaereal conditions, they show irregular shapes due to erosion. In this way, these observations indicate the paleobathymetry for the time of the formation of these edifices. In the case of the work area, the integration of the analyzed data indicates that extrusive events are more widespread than intrusive events. The sedimentary pattern of the work area is similar to that of the Campos Basin. The sedimentary sequences that overlap this volcano-sedimentary section are not directly related to the magmatic pulses in the area; however, they affected the palaeo-relief of the sea floor, which controlled turbiditic deposition.

Chama atenção o fato de que este não é o padrão de ocorrência de surtos da doença na região, e sim interrupção da transmissão após urbanização. Foram investigados os animais considerados reservatórios em potencial para a leishmaniose em domicílios humanos e em áreas de floresta adjacentes. Foram testados anticorpos contra Leishmania spp em amostras de sangue de cães e detectada reatividade pela reação de imunofluorescencia indireta em oito (20,51 % dos examinados. Entre os animais silvestres examinados a espécie Didelphis marsupialis foi predominante, com 20 exemplares capturados, sendo encontrados homoflagelados em três destes e lesões suspeitas de leishmaniose cutanea em dois. Acredita-se que um assentamento populacional desordenado ocorrido nas adjacências tenha causado o deslocamento das populações de vetores e reservatórios naturais em direção às casas do conjunto Hiléia propiciando o surto.This is the result of a two year follow-up of a Cutaneous Leishmaniasis (CL foci in the Hileia urban neighborhood in Manaus. It is important to point out that this is not the usual pattern of Leishmaniasis occurrence in this area. The authors investigated the animal potential reservoir in households and in the surrounding forest area. Samples were tested for leishmaniasis antibodies by RIFI. Eight (20.51% of the examined domestic dogs showed reactivity. In captured wild animals, the Didelphis marsupialis was predominant in twenty specimens, three with homoflagelated in the blood and two with suspicious cutaneous lesions. We believe that the disordered population growth in the nearby area pushed the population of vectors and natural reservoir toward the homes in the Heleia neighborhood creating conditions for this outbreak.

    Full Text Available Foram analisadas hortaliças "in natura", comercializadas na Região Metropolitana de São Paulo, SP-Brasil, visando à pesquisa e à identificação de cistos de protozoários de interesse médico. As hortaliças, constituídas de 50 amostras de cada variedade, consistiram em: alface (Lactuca sativa, variedades lisa e crespa, escarola (Chichorium sp e agrião (Nasturtium officinale. Os resultados evidenciaram elevados percentuais de contaminação em todas as variedades de hortaliças analisadas, porém as freqüências de protozoários foram maiores no agrião. As amostras de alfaces apresentaram os menores percentuais de contaminação, enquanto que a escarola apresentou valores geralmente situados entre o agrião e as alfaces. Observou-se uma grande variedade de protozoários, cujas freqüências de ocorrência na população residente na Região Metropolitana de São Paulo são igualmente elevadas. Os mais freqüentes foram Entamoeba sp (com 4 e 8 núcleos e Giardia sp. Foram também isolados cistos de Iodamoeba sp, Endolimax sp e Chilomastix sp. Os elevados níveis de contaminação fecal encontrados nas amostras analisadas apontam para a importância dos alimentos na transmissão de protozoários intestinais.Vegetables in natura , commercially traded in the metropolitan area of S.Paulo, Brazil, were analised by means of the appropriate methodology with a view to discovering and identifying protozoan cysts of medical interest.

    Full Text Available Realizaram-se entrevistas e análises laboratoriais de 80 amostras de água em 45 propriedades rurais das sub-bacias dos ribeirões Água Limpa e Santa Cruz, em Lavras, Minas Gerais, Brasil, para comparar a qualidade da água para consumo doméstico e agropecuário e seus fatores determinantes. Na sub-bacia Água Limpa, as propriedades são principalmente caracterizadas como moradia, e seus proprietários apresentam baixo grau de escolaridade. Quanto à sub-bacia Santa Cruz, nas propriedades, explora-se a agropecuária, e a maior parte dos proprietários reside na cidade. Com relação aos graus de escolaridade, ela se apresenta muito baixa ou com nível superior. O abastecimento d'água na sub-bacia Água Limpa provém principalmente de lençóis freáticos, enquanto, na sub-bacia Santa Cruz, predominam as águas superficiais, estando seus mananciais contaminados. A percepção dos proprietários sobre a potabilidade da água relaciona-se às características físicas e organolépticas, não à sanitária. Não há relação entre a contaminação fecal e o tipo de manancial, mas sim com a ocupação do solo e as atividades antrópicas.In addition to personal interviews, laboratory analyses were performed using 80 water samples from 45 rural areas that are crossed by the Água Limpa and Santa Cruz streams close to the city of Lavras, southern Minas Gerais State. The results allowed comparing the quality of water used for agriculture and the identification of determinant factors. The Água Limpa stream mostly crosses an area used primarily for housing and characterized by low schooling. Many houses are supplied by shallow water wells and have ordinary cesspits for human waste disposal. All springs are polluted. The Santa Cruz stream displays a different scenario. The land is used mostly for agricultural purposes. Most owners live in town, with widely varied levels of school, from none to university. The houses are supplied by surface water. Most

    Full Text Available A teníase é uma doença que se manifesta no ser humano em decorrência da presença da forma adulta da Taenia sp., enquanto a cisticercose decorre da infecção pelo estágio larvar da Taenia sp. ou Taenia solium, no caso dos suínos e humanos. Foi realizado um estudo transversal visando a determinar a prevalência de cisticercose em suínos e de teníase em 176 propriedades localizadas na zona rural de Viçosa, Minas Gerais (MG. Foram coletadas amostras de sangue de 226 suínos e fezes de 266 humanos, além da realização de um inquérito epidemiológico. Não foi identificada teníase humana, e a prevalência da cisticercose suína foi de 0,4%. As informações obtidas mostraram que a maioria das pessoas possuía o hábito de consumir carne suína não inspecionada; entretanto, todas as pessoas se alimentavam da carne bem aquecida. Em apenas 1,1% das propriedades, o esgoto era depositado diretamente no solo e em 99,4% destas a água era canalizada, enquanto 88,1% dos suínos eram criados presos. Concluiu-se que, na zona rural do município de Viçosa-MG, a prevalência do complexo teníase-cisticercose foi baixa, mostrando ainda um nível de contaminação inferior ao de outros municípios onde o complexo foi estudado.Taeniasis occurs due to the presence of the adult form of Taenia sp. in human beings, and cysticercosis is caused by the presence of the larval stage of T. solium in pigs and humans.

    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

A atividade de mineração, principalmente dos materiais de empréstimo (saibro, apesar de ter deixado um legado negativo ao longo dos últimos 30 anos, sempre serviu de suporte para o desenvolvimento urbano, o que possibilitou o incremento da atividade turística na região. O presente estudo teve como objetivo identificar e quantificar os remanescentes da mineração de saibro, que apresentassem degradação do meio ambiente e risco às comunidades locais, com o intuito de classificar estas áreas quanto ao seu potencial de aproveitamento para exploração de recursos minerais. Para isso lançou-se mão dos sistemas de informações geográficas para gerar um modelo digital de elevação, a partir de redes irregulares triangulares (TIN e se obter o volume das áreas. Posteriormente estas informações foram integradas com os dados de degradação e risco para se chegar ao potencial de aproveitamento das áreas para a mineração. Os resultados alcançados mostram que as 33% das 226 áreas mapeadas apresentam alto potencial para aproveitamento de bens minerais, sendo capazes de sustentar a demanda de suprimentos de baixo valor unitário utilizados na construção civil. O aproveitamento também pode trazer benefícios ambientais uma vez que é capaz de minimizar os riscos ambientais deixados pelas frentes de lavra abandonadas e restringir a ampliação das áreas mineradas.

The objective of this work was to analyze land use in the protected groundwater caption perimeter for the public supply in João Pessoa city (Brazil. From protection perimeters already defined, a study was made of the land use of internal areas through field visits, and observation of satellite image. The exercise of activities prohibited or constrained in the areas that should be protected was noted. The research demonstrated the need to regulate activities that potentially pollute the groundwater and contributes as a useful tool for building policies for the planning of activities on urban land.

    Ceres is one of the second generation heavy ion experiments at CERN's SPS. It is dedicated to the study of electron-positron pairs in relativistic nuclear collisions. NA45 is one of the seven experiments (NA44, NA45, NA49, NA50, NA52, WA97/NA57 and WA98) involved in CERN's Heavy Ion programme which provided evidence for the existence of a new state of matter, the quark-gluon plasma. In this state, quarks, instead of being bound up into more complex particles such as protons and neutrons, are liberated and roam freely. Theory predicts that this state must have existed at about 10 microseconds after the Big Bang, before the formation of matter as we know it today.

    Full Text Available This study aims to show the results of a systematization of studies in the area of English Language Teacher Education carried out at the English Graduate Program at Universidade Federal de Santa Catarina. Fifty-one studies were systematized and five research foci identified. Thirteen published studies of two foci of research were analyzed. Two themes were identified permeating the studies: (1 teachers' beliefs and the contexts of teaching-learning as important mechanisms to shape teachers' pedagogical practices and to determine learning outcomes; and (2 contexts of learning to teach as appropriate and important places for teachers' reflection on their beliefs and knowledge of practice. Most analyzed studies suggest that opening room for reflection in (continuing teacher education programs may provoke changes in teachers' pedagogical practice.Este artigo visa socializar os resultados de uma sistematização de estudos conduzidos no Programa de Pós-Graduação em Inglês da Universidade Federal de Santa Catarina na área de formação de professores de inglês.

    Full Text Available No período de janeiro de 1988 adezembro de 1992, foi realizado diagnóstico de raiva em 289 morcegos através das técnicas de imunofluorescência direta e de inoculação intracerebral em camundongos. Dois morcegos insetívoros da espécie Nyctinomops macrotis se apresentaram positivos, representando 0,69% da amostra. Esses morcegos foram capturados, ainda vivos, em 1988 e 1990, na sala de um apartamento no sétimo andar e no muro de uma casa, respectivamente. Ambos em bairros residenciais. Apresentaram período de incubação de 13 e 11 dias, respectivamente, na prova biológica. A existência de morcegos insetívoros infectados com o vírus da raiva é preocupante, uma vez que essa população parece ser cada vez mais freqüente em áreas urbanas, porém isto não justifica ações predatórias indiscriminadas contra as espécies, principalmente levando-se em consideração a importância do morcego no equilíbrio ecológico da população de insetos, abundante em área urbana.Between January, 1988 and December, 1992 the S. Paulo Animal Disease Control Center subjected 289 bats to rabies examinations, utilizing the direct immunofluorescence and biological techniques. Two insectivorous bats belonging to the species Nyctinomopsmacrotis, representing 0.69% of the total sample, tested positive. Both animals had been captured alive in residential neighborhoods of the city, one in 1988 in the living room of a 7' th floor apartment and the other in 1990 on top of a wall surrounding a private house. In the biological tests, the disease showed incubation periods of 13 and 11 days respectively.Although the existence of infected insectiverous bats in urban areas is cause for concern, indiscriminate predatory action against such species can in no way be justified-particularly bearing in mind their importance in preserving the ecological balance of the insect population so prevalent in cities.

    The aim of this paper is to evaluate the entrance air kerma (Ka,e) and the product air kerma-area (Pka) for chest examinations performed with pediatric patients in a large public hospital of Recife. For this study 89 examinations of patient with ages from zero to 10 years old were evaluated. The results showed that the mean Ka,e values, for patients of 0-1 years old, 1-5 years old and 5-10 years old, were, respectively, 100 mGy, 120 mGy and 100 mGy. The Pka values for newborn patients range from 11,9 to 58,4 mGy.cm{sup 2}, for patients with 1 to 5 years old range from 17 to 192 mGy.cm{sup 2}, and from 30,4 to 136,2 mGy.cm{sup 2} for patients with ages from 5 to 10 years old. The differences in the Pka values are due the different dimensions of the radiation field. For the results its possible to conclude that the Pka values are high, in special for patients with ages from 1 to 5 years old, indicating that the collimation of the radiation field is not adequate.

    A case is made for the use of 22 Na in low activities in preference to 24 Na for routine diagnostic estimation of exchangeable sodium, and is based chiefly on considerations of availability, cost and radiation dosimetry. A method in which only 37 kBq (1 μCi) 22 Na is administered orally is shown to be sufficiently accurate and to possess distinct advantages in terms of cost and convenience with a committed radiation dose no greater than that for a measurement using 24 Na.

    The problem of saturation in the natural gas distribution pipelines in Brazil is not urgent, but it's possible to notice the need of reinforcements in some extensions. Price regulation does not consider this problem yet, but it's already predicted the adoption of a three-part tariff considering a contracted capacity for some industrial consumers - industries that buy more than 500.000 m3/month in the COMGAS distribution area. Some industries, like potteries and glass makers, would probably not suffer strong impacts with the implementation of this three-part tariff, since the majority of their manufacturing processes are continuous. Others sectors would probably have negative impacts with the contracted capacity, like pulp and paper, metallurgy and textile industries. The way that industry will manage the contracted capacity is still unknown. Some possibilities are: considering natural gas as one of the variables in the productions' decision; having a 'Back-up' system when the consumption surpass the contracted capacity; switch fuels when total consumption is above 500.000 m{sup 3}/month, so that the company does not fit in the three-part tariff. The three-part tariff has not been published yet, but it's already necessary a sign to the market that this will occur in the near future, so that the companies involved can already create a strategy for the use of natural gas. This signal is already predicted in the Technical Paper number X of CSPE. (author)

    A large amount of Hg is used for gold extraction through the amalgamation process in the Apolobamba gold mining area located in the northwest part of La Paz, Bolivia. This mining operation may produce a very serious impact on the ecosystems, as well as on the health of miners and inhabitants, mainly due to the primitive methods used in the gold recovery. The objective of this work was to characterize the potential contamination of total Hg in soils, sediments, water, and plants in a mining area of Bolivia. Results showed that there was atmospheric deposition of Hg in the study area. Accumulation of this metal in the studied soils and sediments was one of the highest in the world, but Hg in aquatic solution was below the detection limit of the analytical method of the studied lakes and rivers. The highest concentration of Hg was found in the river sediments of the Sunchullí- Viscachani (102 mg kg-1, and in the sediments of Sunchullí and Viscachani lakes (12.3 and 11.7 mg kg-1, respectively. These concentrations may pose a serious problem for aquatic life, related ecosystems and human health. Therefore, there is a need to study Hg availability and speciation in soils and sediments to better understand the cycling of Hg in the area.

    Mercury contamination in the Amazon basin is a consequence of the intensive and extensive use of metallic Hg in gold mining activities which use the amalgamation process. Mercury vapor is the main form of Hg released in the Amazonian ecosystem. However, some studies have shown that enhanced biotransformation of inorganic mercury into organic Hg is occurring. These two forms of Hg have some properties in common but differ in toxicity and metabolic behavior. Knowledge of the fate and transport of Hg in the Amazon basin is especially important for the assessment of the extent of contamination, as well as the characterization of exposed groups. the present study attempts to evaluate the Hg exposure scenario as well as to assess the quantitative risk (from Hg emission) for workers in gold-dealers' shops and for the general population in the urban area of Alta Floresta.

    Mercury contamination in the Amazon basin is a consequence of the intensive and extensive use of metallic Hg in gold mining activities which use the amalgamation process. Mercury vapor is the main form of Hg released in the Amazonian ecosystem. However, some studies have shown that enhanced biotransformation of inorganic mercury into organic Hg is occurring. These two forms of Hg have some properties in common but differ in toxicity and metabolic behavior. Knowledge of the fate and transport of Hg in the Amazon basin is especially important for the assessment of the extent of contamination, as well as the characterization of exposed groups. the present study attempts to evaluate the Hg exposure scenario as well as to assess the quantitative risk (from Hg emission) for workers in gold-dealers' shops and for the general population in the urban area of Alta Floresta. The way that are was populated and the regional and local economy history, particularly in connection with the commercialization of gold in the region, are important factors in the study of the exposure scenario in Alta Floresta. Assessment of exposure pathways has shown that the adult and infant populations of Alta Floresta are exposed to low dose levels of Hg.

    Full Text Available Environmental contamination by arsenic compounds in the Ribeira River Valley, São Paulo, Brazil has already been observed. Lead mining and refining activities had been carried on since late colonial times and finished recently, at the end of 1995. The source of As in the region is known to be mainly from arsenopirite geological presence in the lead ore. Chronic exposure to arsenic compounds may cause peripheral vascular disorders, hyperpigmentation, hiperkeratosis and cancer of the skin, bladder, lung, liver and other internal organs. The purpose of this study was to assess children exposure to arsenic from environmental sources in the region. Urine samples from children between 7 to 14 years old were collected at the following localities: Cerro Azul (Paraná; urban areas of Ribeira (São Paulo and Adrianópolis (Paraná; Vila Mota neighborhood (rural area of Adrianópolis and Serra neighborhood (Iporanga, São Paulo, identified as groups 1, 2, 3 and 4, respectively. Group 1 was considered as non-exposed control group. Toxicologically relevant forms of As were determined by atomic absorption spectrometry with hydride generation system. The median values of urine arsenic levels obtained in groups 1, 2, 3 and 4 were respectively: 3.60, 6.30, 6.41 e 8.94μg/L.Contaminação ambiental por compostos de arsênio no Vale do Ribeira, São Paulo, Brasil, tem sido já observada. As atividades de mineração e refinamento do chumbo têm ocorrido desde a época colonial e foram encerradas recentemente, no final de 1995. A principal fonte de arsênio na região é arsenopirita que ocorre geologicamente no minério de chumbo. Exposição crônica aos compostos de arsênio podem causar desordens vasculares periféricas, hiperpigmentação, hiperqueratose, além de câncer de pele, bexiga, pulmão, fígado e outros órgãos. O objetivo do presente estudo foi avaliar a exposição de crianças ao arsênio proveniente de fontes ambientais na região. Amostras de

    Full Text Available A regeneração de sub-bosques em plantios homogêneos tem estreita dependência de florestas vizinhas. Outros fatores exercem influência, como a ecologia da dispersão da espécie, os efeitos de borda e clareiras. Diante disto, procurou-se conhecer a florística e a estrutura da vegetação lenhosa de espécies nativas sob plantio de Eucalyptus em área de Cerrado na Floresta Nacional de Paraopeba, MG, e verificar a variação da riqueza, da densidade e de indivíduos zoocóricos e anemocóricos da borda para o interior do talhão. Para tal, foram alocadas cinco parcelas de 5×40 m, subdivididas em parcelas 5×10 m. Foram encontradas 47 espécies e destas as que se destacaram foram Magonia pubescens A. St.-Hil.e Miconia albicans (Sw. Triana, principalmente quanto à alta densidade. Das espécies amostradas 53% possuem dispersão zoocórica e 43% anemocórica. Verificou-se também a diminuição da riqueza, da densidade e da percentagem de indivíduos anemocóricos da borda para interior. Porém a percentagem de indivíduos zoocóricos aumentou no interior do talhão. A maior riqueza e densidade na borda dá-se pela dificuldade da dispersão de diásporos no interior do fragmento. O índice de diversidade (H'= 2,49 encontrado para este estudo foi próximo aos valores observados em estudos em regeneração sob Eucalyptus em áreas de Cerrado.The regeneration of understory in homogeneous stands is closely dependent of neighbour forests.

    We have designed and implemented a minimum bias trigger together with a fiducial volume trigger for the experiment NA27, performed at the CERN SPS. A total of more than 3 million bubble chamber pictures have been taken with a triggered cross section smaller than 75% of the total inelastic cross section. Events containing charm particles were triggered with an efficiency of 98 +2 sub(-3)%. With the fiducial volume trigger, the probability for a picture to contain an interaction in the visible hydrogen increased from 47.3% to 59.5%, reducing film cost and processing effort with about 20%. The improvement in data taking rate is shown to be negligible. (author)

    Quando viam um cometa, os antigos gregos imaginavam uma estrela com uma vasta cabeleira. Não à toa, a palavra deriva do termo koma, que significa cabelo. Constituídos por fragmentos de gelo e gases, os cometas possuem um núcleo sólido, que pode ter vários quilômetros de diâmetro, e uma cauda que sempre aponta na direção contrária ao Sol, devido aos ventos solares. Graças à aparência de pontos luminosos em movimento (ao contrário de outros astros, que parecem estáticos), esses corpos celestes foram interpretados por diferentes povos com muito misticismo, inspirando mitos tanto de boas-novas como de maus presságios. Conheça algumas dessas histórias:

  1. NA48 prototype calorimeter

    CERN Multimedia

    1990-01-01

    This is a calorimeter, a detector which measures the energy of particles. When in use, it is filled with liquid krypton at -152°C. Electrons and photons passing through interact with the krypton, creating a shower of charged particles which are collected on the copper ribbons. The ribbons are aligned to an accuracy of a tenth of a millimetre. The folding at each end allows them to be kept absolutely flat. Each shower of particles also creates a signal in scintillating material embedded in the support disks. These flashes of light are transmitted to electronics by the optical fibres along the side of the detector. They give the time at which the interaction occurred. The photo shows the calorimeter at NA48, a CERN experiment which is trying to understand the lack of anti-matter in the Universe today.

    The thermochemical interaction between the nuclear fuel (uranium and plutonium mixed oxides) and the sodium has been investigated and particularly the three phase diagrams: U - O - Na; Pu - O - Na; U,Pu - O - Na. High temperature neutron diffraction, microcalorimetry and powder X-ray diffraction were used for the characterization of the compounds synthetized. This study allowed to complete the knowledge about each of these diagrams and to measure some physical and thermal properties on the compounds. The limits on the modelization of the fuel-sodium interaction are discussed from the results of the UO 2 - Na reaction [fr

Para tanto discutir-se-á, em primeiro lugar, e brevemente, o que são valores morais, ou éticos, e como a escola pode situar-se em relação a eles. Em seguida, serão relatadas algumas observações a respeito de valores de professores e práticas daí decorrentes. São comentados resultados de pesquisa que ilustram a transmissão de valores de forma doutrinal e a educação moral e cívica tal como realizada na ditadura militar, e, por outro lado, a posição relativista e/ou de laissez-faire que certas escolas podem adotar, metodologicamente, sobre a educação em valores. Finalmente, defender-se-á a idéia de que é necessária uma discussão sobre valores pelos diversos membros da escola e uma opção por uma metodologia para ensiná-los, seja os professores, em sua formação inicial e continuada, seja os alunos. A teoria de desenvolvimento moral de Jean Piaget será apresentada como uma referência possível para a educação em valores. Exemplos de situações escolares de conflito de valores entre direção, pais e alunos são discutidas para ilustrar como uma escola pode adotar um procedimento democrático de educação em valores, que se apresenta como um terceiro caminho possível de educação moral nas escolas, além das posições doutrinárias ou relativistas.

    Full Text Available Para Hume, filosofar é uma atividade semelhante às demais ocupações humanas. A decisão que leva à atividade filosófica é menos resultado de uma argumentação teórica do que fruto de um cálculo prático, que é entendido como uma caça ou um jogo. O objetivo deste trabalho será o de mostrar que no jogo filosófico perde quem joga sério demais. A aposta na filosofia tem que passar pelo bom humor e pela diversão: uma resposta a Pascal?For Hume, philosophy is in itself neither more nor less important than other human activities. On the contrary, it can be explained from its resemblance with game and hunting. If one chooses to dedicate himself to philosophy, his decision is not the consequence of logical reasoning, but depends on practical evaluation, which has something to do with gambling. The following text tries to show that in philosophy, like in other games, the loser will be the one who plays too earnestly. The philosophical game requires good humour and some relaxation: Is this a good answer to Pascal's pari?

    Full Text Available Com o objetivo de conhecer a composição química e os requisitos de qualidade da cachaça produzida na Região Noroeste do Estado do Rio Grande do Sul, foram analisadas 27 amostras de cachaça, produzidas e comercializadas em 18 municípios pertencentes às microrregiões Ijuí, Cruz Alta, Santa Rosa e Três Passos, que integram o Noroeste do Rio Grande do Sul, Brasil, e compararam-se os valores encontrados com aqueles estabelecidos pela Legislação. Para as análises estatísticas, aplicaram-se os testes de ANOVA e Tukey. As amostras avaliadas apresentaram valores médios de teor alcoólico, acidez, álcoois superiores, aldeídos, ésteres e metanol dentro do que estabelece a Legislação. Entretanto os valores de intervalo de concentração para estes mesmos parâmetros revelaram amostras fora do estipulado por Lei, indicando falta de conhecimento tecnológico de produção por parte de alguns dos produtores. Sugere-se a ampliação do presente estudo, com a finalidade de se investigar outros aspectos tecnológicos, tendo em vista a otimização dos processos de fabricação e a melhoria da qualidade da bebida.With the aim of knowing the chemical composition and quality requirement of the sugar cane spirit, "cachaça" produced in the Northwest Region of the Rio Grande do Sul State, 27 samples of "cachaça" were analyzed, produced and marketed in 18 municipal districts that belong to the areas of Ijuí, Cruz Alta, Santa Rosa and Três Passos, which are in the Northwest of Rio Grande do Sul State, Brazil. The values found were compared with the ones established in the Legislation. Concerning the statistical analyses, the ANOVA and Tukey tests were applied. The evaluated samples showed a medium value of alcoholic text, acidity, higher alcohols, aldehydes, esters and methanol within what the Legislation establishes. However, the interval values of concentration to these same parameters revealed samples that are not stipulated by law, showing a

    1987-01-01

    The ability of ATP, CTP, ITP, GTP, and UTP to support ouabain-sensitive accumulation of Na + by proteoliposomes with a reconstituted Na/K-pump was investigated. At a low [Na + ]/[K + ] ratio in the medium (20 mM/50 mM), a correlation is observed between the proton-accepting capacity of the nucleotide and its effectiveness as a substrate of active transport. To test the hypothesis of the importance of the presence of a negative charge in the 1-position of the purine (3-pyrimidine) base of the nucleotide for mutual transitions between the Na- and K-conformations of Na,K-ATPase they used two analogs of ATP: N 1 -hydroxy-ATP, possessing proton acceptor capacity, and N 1 -methoxy-ATP, in the molecule of which the negative charge is quenched by a methyl group. The first substrate supports active accumulation of Na + in proteoliposomes at the same rate as ATP, whereas the second substrate is relatively ineffective

    Full Text Available This study proposes to recover the Mandacarú Stream, located in the city of Maringá, Paraná State, Brazil by developing a greenway. The stream in question has been extremely degraded, principally by human activity. The proposed methodology begins with preparing a scenario for the valley floor with a greenway in place. This is followed by an investigation of the corridor’s ecological and cultural variables, taking a holistic view to synthesise and diagnose the information collected. Guidelines for recovering the valley floor and developing the greenway are then drawn up to direct the preparation of the final plan. As a result, the principal environmental impacts that undermine the quality of the study area were surveyed, such as erosion, loss of riparian vegetation, illegal sewage connections and lack of environmental education. A list of guidelines was developed for recovering and conserving the area, in combination with the development of a greenway along the valley floor. It is hoped that these guidelines can assist a future intervention at this location and that the proposed method can be used as the basis for the recovery of other urban valley floors.O presente estudo propõe a recuperação do fundo de vale do córrego Mandacarú, localizado na cidade de Maring, Estado do Paraná, por meio da implantação de um parque linear.

    Full Text Available We compared the effects of habitat disturbance on the feeding ecology of two local populations of Tropidurus torquatus (Wied, 1820 in restinga habitats on Ilha da Marambaia, Southeastern Brazil. Both populations presented a relatively diverse diet and differ in the number (D Max = 0.22, DF = 2, p = 0.00 and volume of prey consumed (D Max = 0.82, DF = 2, p = 0.00. Ants were the most frequent and numerous preys in both areas, and plant matter and coleopterans were the most important alimentary items in volume. The population from the disturbed area presented a larger niche breadth for number of prey items consumed (Bi num = 3.06 and volume (Bi vol = 2.98, when compared to the other population (Bj num = 2.44, Bj vol = 1.52. Niche overlap was higher for number of items consumed between the populations (Oij num = 0.82 but lower for volume (Oij vol = 0.05. Our data suggest dietary differences between the two lizard populations, and these differences may be associated with environmental modifications. Our main hypothesis to explain the dietary differences is based in the Optimal Foraging Theory. However, the alimentary behavior, and consequently the diet of these lizards, seems to be constrained phylogenetically, with a pattern that may have evolved in the ancestor of all iguanids.Comparamos os efeitos da degradação ambiental sobre a ecologia alimentar de duas populações de Tropidurus torquatus (Wied, 1820 em áreas de restinga da Ilha da Marambaia, sudeste do Brasil.

    Full Text Available O momento nazista permanece um enigma impensado de que a cultura contemporânea continua cativa. O autor levanta a hipótese de que a persistência desse enigma e seus estragos duráveis se devem à insistência dos pensamentos político, sociológico e filosófico em construírem o nazismo à luz da metáfora hobbesiana do Leviatã. Propõe retomar a questão do nazismo sob a perspectiva do Behemoth, antônimo do Leviatã. Para tanto, sugere a necessidade de retornar a Freud e à psicanálise, balizas de um possível novo pensamento do político que escrutine a destrutividade nazista. Propõe ainda sondar as homologias entre nazismo, corjas e máfias, com base na figura da " heroicização da violência" que lhes seria comum. E avança um modelo " econômico" : a quimera, suscetível de capturar o caráter heterotópico e heterocrônico de sua construção criminosa.The paths of Behemoth. The Nazi moment remains as the thoughtless enigma of which contemporary culture is still captive. The author raises the hypothesis where the persistency of this enigma and its durable damages are due to the insistence of the political, social and philosophical thoughts in building the Nazism at the view of the Hobbesian metaphor of Leviathan. It is here proposed to resume the Nazism matter under Behemoth's perspective, antonym to Leviathan. For such, it is suggested a necessity to look back at Freud and the psychoanalysis, structured by a possible new political thought which scrutinizes the destructivity of the Nazism. It is also here proposed to gaze at the homologies between Nazism, mafias and gangs, with a base in the figure of " violence as a heroically act" that are their common ground. The author also advances an economical model: the chimera susceptible to capture the heterotopic and heterochronic character of its criminal construction.

    [sup 23]Na MRI changes from the acute to chronic phase were investigated in seven patients with cerebral infarcts. They showed no signal increase during the first 13 h after the stroke and revealed a definite signal increase thereafter. This reached a maximum 45-82 h after stroke and became sightly less marked in the subacute and chronic phases, probably as a result of disappearance of cerebral oedema. In the early acute phase of stroke, [sup 23]Na MRI appears to fail to demonstrate Na[sup +] increases in the ischaemic area, due presumably to the invisibility on MRI of intracellular [sup 23]Na in the intact brain. The increase more than 13 h after stroke, during which ischaemic cells are likely to die, is presumably because of increased visibility of intracellular [sup 23]Na in the dead cells. [sup 23]Na MRI is apparently insensitive to early ischaemic changes, but may be useful for assessing the cell viability in the ischaemic brain. (orig.)

    In two decades, the technology of petroleum production in Campos' Basin stood out in the international scenery, as pioneer in the exploration in deep waters. In contrast, the fishing activities developed in the Colonies of Fishermen follow the traditions of the craft fishing with their procedures and rudimentary methods. The Campos Basin Business Unit chose the community of fishermen of its influence area as a collectivity to who intends to offer projects and solutions. The proposal of the Pilot Project of Artificial Reefs appears, using disabled materials of the oil industry and gas for formation of fishing with objective of generating socioeconomic benefits for the craft fishermen. The mark of this article is to point that the methodology adopted by PETROBRAS, that as concrete result, receives from IBAMA the authorization for release of the structures, in Rio das Ostras. It is waited that the conviviality will be beneficial for the communities, developing new technologies, while to the Company it is possible to assist the needs of the fishermen. (author)

    Full Text Available O atual quadro da epidemia de HIV/Aids reforça a tendência de associação com a exclusão social, uma vez que as pessoas mais vulneráveis à infecção são aquelas que sofrem com as consequências da pobreza e/ou pertencem a grupos minoritários. Esse perfil suscita ações de combate à discriminação e ao estigma, não só ao HIV/Aids, mas a outras formas de discriminação e opressão social associadas à síndrome, como as de gênero, raça/etnia e classe social. Este estudo propõe discutir, do ponto de vista psicossocial, o papel das ONGs/Aids como promotoras da formação de redes sociais de suporte, focando no processo de politização dos vínculos afetivos das pessoas que vivem com o HIV/Aids (PHA, através da participação política. Tendo seu campo empírico em uma ONG/Aids situada na Grande São Paulo. Consideramos que uma ONG pode contribuir como polo articulador ou rearticulador de novas redes sociais para PHA. Nesse sentido, supomos a ONG/Aids como um espaço de transição para aqueles que buscam ajuda na instituição, incrementando um quadro com diferentes atores sociais que contribuiriam para a formação de uma rede social que daria suporte para a superação das consequências do HIV/Aids. A partir dos relatos, destacamos alguns dos aspectos psicossociais que favorecem e/ou dificultam o processo de rearticulação dessas pessoas em novas redes sociais através de situações relacionadas: às trajetórias de vida marcadas por opressões sociais e pelo individualismo, ambos reforçados pelo impacto do HIV/Aids; às contradições da convivência no espaço institucional; e às possibilidades de transformação dos vínculos comunitários por meio da solidariedade e cidadania.The current picture of the HIV/Aids epidemic has strengthened the trend of connection with social exclusion, in the sense that the people who are most vulnerable to the infection are those that suffer from the consequences of poverty and/or belong

Mosquitoes captured were analyzed by standardized indicator species analysis (ISA before and during different flooding phases (253 m and 257 m elevations. The local human population was studied by means of parasitological (thin/thick blood smears, molecular (PCR and serological tests. Serological tests consisted of Enzyme Linked Immunosorbent Assay (ELISA with synthetic peptides of the circumsporozoite protein (CSP from classic Plasmodium vivax, P. vivax variants (VK247 and "vivax-like", P. malariae and P. falciparum and Indirect Immunofluorescence Assay (IFA with asexual forms of P. vivax, P. malariae and P. falciparum. The results of the entomological survey indicated that, although the Anopheles darlingi population increased after the flooding, the population density remained very low. No malaria, parasite infection or DNA was detected in the inhabitants of the study area. However, there was a low frequency of antibodies against asexual forms and a significant prevalence of antibodies against P. vivax, P. vivax variants, P. falciparum and P. malariae; the presence of these antibodies may result from recent or less recent contact with human or simian Plasmodium (a parallel study in the same area revealed the existence of a sylvatic cycle. Nevertheless, these results suggest that, as in other places where malaria is present and potential vectors circulate, the local epidemiological conditions observed could potentially support the transmission of malaria in Porto Primavera Lake if infected individuals are introduced in sufficient numbers.

    Full Text Available This study investigates patterns of forest structure and tree species diversity in an anthropogenic palm grove and undisturbed areas at the seasonally-dry Pinkaití research station, in the Kayapó Indigenous Area. This site, managed by the Conservation International do Brasil, is the most southeastern site floristically surveyed in the Amazon until now. The secondary and a nearby undisturbed forest were sampled in a group of 52 floristic plots of 0.0625-ha (25x25-m where all trees with DBH > 10 cm were measured and identified. The analyses were complemented with other two floristic plots of 1-ha (10x1000-m. The present study has shown that the Pinkaití, like other seasonally-dry forests, have great heterogeneity in forest structure and composition, associated with biotic characteristics of the most important tree species, natural disturbance and history of land-use. The palm grove, moderately dominated by the arborescent palm Attalea maripa (Aubl. Mart., presented high tree species diversity and was floristically similar to undisturbed forests at the study site. It is discussed the importance of large arborescent palms for the seasonally-dry Amazon forests regeneration.Este estudo compara a florística e estrutura e a diversidade de espécies arbóreas de um palmeiral antropogênico e áreas não perturbadas na floresta sazonalmente seca da base de pesquisas ecológicas do Pinkaití, na Terra Indígena Kayapó.

    The image shows the new rare Kaon decay experiment at CERN, called NA62. The NA62 experiment is 270 metres long and includes a 120-metre-long vacuum tank, shown here, housing several of the particle detectors. (Note: the experiment axis is a straight line, the curving of the tank is an optical effect of the photo.) Kaons are particles that decay into lighter elementary particles. The kaon decay processes are mostly well known, except for some very rare decay modes. For example, NA62 is investigating a rare decay predicted by the Standard Model in which a kaon decays into one pion and two neutrinos. This process occurs only once every 10 billion decays. The understanding of such ultra-rare decays are of great importance because they test the Standard Model in energy ranges not accessible by direct measurements. They are therefore complementary to the measurements at the LHC. ultra high definition on demand (photolab@cern.ch).

    1978-01-01

    The handbook is intended for use by present and future designers in the Liquid Metals Fast Breeder Reactor (LMFBR) Program and by the engineering and scientific community performing other type investigation and exprimentation requiring high-temperature sodium and NaK technology. The arrangement of subject matter progresses from a technological discussion of sodium and sodium--potassium alloy (NaK) to discussions of varius categories and uses of hardware in sodium and NaK systems. Emphasis is placed on sodium and NaK as heat-transport media. Sufficient detail is included for basic understanding of sodium and NaK technology and of technical aspects of sodium and NaK components and instrument systems. Information presented is considered adequate for use in feasibility studies and conceptual design, sizing components and systems, developing preliminary component and system descriptions, identifying technological limitations and problem areas, and defining basic constraints and parameters.

    The β-decay of Na32 has been studied using β-γ coincidences. New transitions and levels are tentatively placed in the level scheme of Mg32 from an analysis of γ-γ and β-γ-γ coincidences. The observation of the indirect feeding of the 2321 keV state in Mg32 removes some restrictions previously placed on the spin assignment for this state. No evidence of a state at 2117 keV in Mg32 is found. Previously unobserved weak transitions up to 5.4 MeV were recorded but could not be placed in the decay scheme of Na32.

    The Super Proton Synchrotron (SPS) at CERN covers one of the most interesting regions of the phase diagram (T - \\mu_{B}) of strongly interacting matter. The study of central Pb+Pb collisions by NA49 indicate that the threshold for deconfinement is reached already at the low SPS energies. Theoretical considerations predict a critical point of strongly interacting matter at energies accessible at the SPS. The NA61/SHINE experiment, a successor of the NA49 project, will study hadron production in p+p, p+A, h+A, and A+A reactions at various energies. The broad physics program includes the investigation of the properties of strongly interacting matter, as well as precision measurements of hadron spectra for the T2K neutrino experiment and for the Pierre Auger Observatory and KASCADE cosmic-ray projects. The main physics goals of the NA61/SHINE ion program are to study the properties of the onset of deconfinement at low SPS energies and to find signatures of the critical point of strongly interacting matter.

    Europlanet RI / NA2 Science Networking [1] focused on determining the major goals of current and future European planetary science, relating them to the Research Infrastructure that the Europlanet RI project [2] developed, and placing them in a more global context. NA2 also enhanced the ability of European planetary scientists to participate on the global scene with their own agenda-setting projects and ideas. The Networking Activity NA2 included five working groups, aimed at identifying key science issues and producing reference books on major science themes that will bridge the gap between the results of present and past missions and the scientific preparation of the future ones. Within the Europlanet RI project (2009-2012) the NA2 and NA2-WGs organized thematic workshops, an expert exchange program and training groups to improve the scientific impact of this Infrastructure. The principal tasks addressed by NA2 were: • Science activities in support to the optimal use of data from past and present space missions, involving the broad planetary science community beyond the "space club" • Science activities in support to the preparation of future planetary missions: Earth-based preparatory observations, laboratory studies, R&D on advanced instrumentation and exploration technologies for the future, theory and modeling etc. • Develop scientific activities, joint publications, dedicated meetings, tools and services, education activities, engaging the public and industries • Update science themes and addressing the two main scientific objectives • Prepare and support workshops of the International Space Science Institute (ISSI) in Bern and • Support Trans National Activities (TNAs), Joined Research Activities (JRAs) and the Integrated and Distributed Information Service (IDIS) of the Europlanet project These tasks were achieved by WG workshops organized by the NA2 working groups, by ISSI workshops and by an Expert Exchange Program.

    Full Text Available O processo de mineração provoca uma desfiguração do terreno e uma completa alteração da paisagem. Um problema bastante comum na revegetação de áreas degradadas na exploração mineral compreende a compactação do solo/substrato devido ao intenso tráfego de máquinas e movimentação de terra. Os problemas mais comuns da compactação de uma superfície degradada são: aumento da resistência mecânica à penetração radicular, redução da aeração, alteração do fluxo de água e calor, comprometendo a disponibilidade de água e nutrientes do local. Sendo assim, o presente trabalho teve como objetivo básico diagnosticar, de forma espacial, a compactação de uma área minerada por meio da resistência mecânica à penetração. O diagnóstico da área compactada foi efetuado para orientar uma futura subsolagem no local visando posterior revegetação. Através dos estudos, concluiu-se que o método de interpolação (krigagem, de acordo com a variação espacial da resistência mecânica à penetração, permite dividir a área estuda em subáreas possibilitando um futuro gerenciamento localizado de forma a reduzir custos e interferências desnecessárias ao ambiente. O método mostrou-se bastante eficiente e pode ser utilizado em diagnóstico da compactação em áreas mineradas, prevendo necessidade de subsolagem.A quite common problem in the recovery of degraded areas in the mineral exploration understands the compaction of the soil due to the intense traffic of machines and earth movement. The most common problem of the compaction of a degraded surface is: increase of the mechanical resistance to the penetration of the rooats, reduction of the aeration, alteration of the water flow and heat. Thus the present work had the basic objective of diagnosing the compaction of a degraded area by mining in a space way, through the mechanical resistance the way penetration to guide a future subsoiling in the place seeking recovery

As infecções relacionadas à assistência à saúde (IRAS, um dos problemas enfrentados na área, é alvo de pesquisas que intentam criar procedimentos e estratégias no sentido de prevenir tais eventos. A higienização de mãos, por ser a medida mais simples no controle das IRAS e, paradoxalmente, a que possui mais baixo índice de adesão entre os médicos, é alvo de inúmeros programas e campanhas. A necessidade de reversão do quadro apontado tem gerado extensa literatura que, entre outros, identifica barreiras e fatores de risco para a baixa adesão a normas e procedimentos de higienização de mãos, como também busca compreender os aspectos comportamentais envolvidos. Este artigo apresenta alguns modelos teóricos explicativos voltados para a compreensão da dinâmica comportamental que envolve a consecução do erro e da violação e realiza uma análise com possibilidades à depreensão do processo. Por fim, considera-se que os modelos explicativos apresentados, conjuntamente, trazem contribuições passíveis de aplicação na prática e que a identificação e compreensão dos mecanismos de defesa coletivos levariam aos fatores que se encontram em jogo na baixa adesão aos procedimentos de higienização de mãos por parte dos médicos, a despeito das evidências existentes.In 1999, the report by the Institute of Medicine (IOM, pointed that there are significant adverse events and that more than half of these occurrences were caused by medical errors, provoking numerous actions and research on Patient Safety.

    Full Text Available Abstract Background When cells are exposed to high salinity conditions, they develop a mechanism to extrude excess Na+ from cells to maintain the cytoplasmic Na+ concentration. Until now, the ATPase involved in Na+ transport in cyanobacteria has not been characterized. Here, the characterization of ATPase and its role in Na+ transport of alkaliphilic halotolerant Aphanothece halophytica were investigated to understand the survival mechanism of A. halophytica under high salinity conditions. Results The purified enzyme catalyzed the hydrolysis of ATP in the presence of Na+ but not K+, Li+ and Ca2+. The apparent Km values for Na+ and ATP were 2.0 and 1.2 mM, respectively. The enzyme is likely the F1F0-ATPase based on the usual subunit pattern and the protection against N,N'-dicyclohexylcarbodiimide inhibition of ATPase activity by Na+ in a pH-dependent manner. Proteoliposomes reconstituted with the purified enzyme could take up Na+ upon the addition of ATP. The apparent Km values for this uptake were 3.3 and 0.5 mM for Na+ and ATP, respectively. The mechanism of Na+ transport mediated by Na+-stimulated ATPase in A. halophytica was revealed. Using acridine orange as a probe, alkalization of the lumen of proteoliposomes reconstituted with Na+-stimulated ATPase was observed upon the addition of ATP with Na+ but not with K+, Li+ and Ca2+. The Na+- and ATP-dependent alkalization of the proteoliposome lumen was stimulated by carbonyl cyanide m - chlorophenylhydrazone (CCCP but was inhibited by a permeant anion nitrate. The proteoliposomes showed both ATPase activity and ATP-dependent Na+ uptake activity. The uptake of Na+ was enhanced by CCCP and nitrate. On the other hand, both CCCP and nitrate were shown to dissipate the preformed electric potential generated by Na+-stimulated ATPase of the proteoliposomes. Conclusion The data demonstrate that Na+-stimulated ATPase from A. halophytica, a likely member of F-type ATPase, functions as an electrogenic Na

    We investigate the desorption of Na atoms from large Na clusters deposited on dielectric surfaces. High-resolution translational energy distributions of the desorbing atoms are determined by three independent methods, two-photon laser-induced fluorescence, as well as single-photon and resonance......-enhanced two-photon ionization techniques. Upon variation of surface temperature and for different substrates (mica vs lithium fluoride) clear non-Maxwellian time-of-flight distributions are observed with a cos θ angular dependence and most probable kinetic energies below that expected of atoms desorbing from...... atoms are scattered by surface vibrations. Recent experiments providing time constants for the decay of the optical excitations in the clusters support this model. The excellent agreement between experiment and theory indicates the importance of both absorption of the laser photons via direct excitation...

    Variations in soil attributes occur based on relief forms and parent material. The objective of this research was to study the influences of geomorphic surfaces on the spatial distribution of soil attributes in a sugarcane cultivation area. First, 530,67 hectares were mapped by using a Global Positioning System. Then, a Digital Elevation Model was developed and geomorphic surfaces were identified and delimited, according to topographic and stratigraphic criteria based on detailed field investigations. Soil samples were collected every 7 ha, at 0.0-0.25 m and 0.80-1.00 m depths, totalizing 134 samples. Texture, Ca, K, Mg, SB, CEC, V%, pH, and OMS analyses were carried out as well as descriptive statistics and geostatistics analysis. It was concluded that the geostatistic techniques and digital elevation model helped to notice that soil attributes presented limits close to the geomorphic surfaces ones.

LR Kitajska je v zadnjih petdesetih letih počasi in postopoma začela uveljavljati določene spremembe v vzgojno-izobraževalni sistem. Kakšne so te spremembe in koliko nanje še vedno vpliva konfucianizem, bo osrednja tema pričujočega članka. Konfucianizem danes na Kitajskem ni preveč popularen, izobraženci pa so se razporedili v dve skupini: eni trdijo, da je njegov vpliv še vedno velik, drugi pa zatrjujejo, da nima več nobenega vpliva na sodobno življenje. Katera stran ima prav? Konfucij je v prvi vrsti poudarjal pomembnost moralnih vrednot vsakega človeka in prav moralne vrednote, za katere se je zavzemal, so še danes trdno zasidrane v kitajski kulturi. Ali je torej sploh mogoče popolnoma izriniti Konfucija iz sodobnega izobraževanja?

    Highly conductive porous Na-embedded carbon nanowalls (Na@C), which were recently invented, have exhibited excellent performance for dye-sensitized solar cells and electric double-layer capacitors. In this work, Na@C was demonstrated as an excellent electrode material for capacitive deionization (CDI). In a three-electrode configuration system, the specific capacity of the Na@C electrodes can achieve 306.4 F/g at current density of 0.2 A/g in 1 M NaCl, which is higher than that (235.2 F/g) of activated carbon (AC) electrodes. Furthermore, a high electrosorption capacity of 8.75 mg g-1 in 100 mg/L NaCl was obtained with the Na@C electrodes in a batch-mode capacitive deionization cell. It exceeds the electrosorption capacity (4.08 mg g-1) of AC electrodes. The Na@C electrode also showed a promising cycle stability. The excellent performance of Na@C electrode for capacitive deionization (CDI) can be attributed to its high electrical conductivity and large accessible surface area.

    Generally, the phase diagrams are always used to understand the present state of compounds at certain temperature. In order to understand the corrosion behavior of structural material for FBR by main sodium compounds (Na 2 O, Na 2 O 2 and NaOH), it is very important to comprehend the phase diagrams of their compounds. However, only Na 2 O-NaOH pseudo-binary phase diagram had been investigated previously in this system. There is no study of other pseudo-binary or ternary phase diagrams in the Na 2 O-Na 2 O 2 -NaOH system. In this study, in order to clarify the present states of their compounds at certain temperatures, the pseudo-binary and ternary phase diagrams in the Na 2 O-Na 2 O 2 -NaOH system were prepared. A series of thermal analyses with binary and ternary component system has been carried out using the differential scanning calorimetry (DSC). The liquidus temperature and ternary eutectic temperatures were confirmed by these measurements. The beneficial indications for constructing phase diagrams were obtained from these experiments. On the basis of these results, the interaction parameters between compounds which were utilized for the Thermo-Calc calculation were optimized. Thermo-Calc is one of thermodynamic calculation software. Consequently the accurate pseudo-binary and ternary phase diagrams were indicated using the optimized parameters. (author)

    Full Text Available A homocisteína, formada a partir da metionina hepática, é metabolizada nas vias de desmetilação e de transulfuração, sendo que seus valores plasmáticos e urinários refletem a síntese celular. Sua determinação, realizada em jejum e após sobrecarga de metionina, caracteriza as diferenças dessas vias metabólicas, principalmente quando de natureza genética. A hiper-homocisteinemia tem sido associada a maior risco de eventos aterotrombóticos, e a literatura sugere associação causal, independente de outros fatores de risco para doença arterial. Diminuição da homocisteína plasmática para valores normais é seguida de redução significante na incidência de doença aterotrombótica. A relação entre homocisteína e o fígado vem adquirindo importância nos dias atuais, uma vez que alterações das lipoproteínas e da depuração de metionina são comuns em pacientes com doença hepática crônica (hepatocelular e canalicular. O tratamento da hiper-homocisteinemia fundamenta-se na suplementação alimentar e medicamentosa de ácido fólico e vitaminas B6 e B12.Homocysteine, formed from hepatic methionine, is metabolized through the pathways of demethylation and transsulfuration. Its plasmatic and urinary values reflect the cell synthesis. Its determination after fasting and increased infusion of methionine shows the differences of these two metabolic pathways, mainly when it is related to genetic diseases. Hyperhomocysteinemia has been associated with a higher risk of vascular thrombotic events. Several authors suggest a causal relationship between these events independently of other risk factors for vascular diseases. Decrease in plasmatic homocysteine to normal levels is followed by a significant reduction on the incidence of vascular thrombotic events. The correlation between the liver and homocysteine is becoming more important because of the recent findings that alterations of lipoproteins and methionine clearance are

  19. Silicene for Na-ion battery applications

    KAUST Repository

    Zhu, Jiajie

    2016-08-19

    Na-ion batteries are promising candidates to replace Li-ion batteries in large scale applications because of the advantages in natural abundance and cost of Na. Silicene has potential as the anode in Li-ion batteries but so far has not received attention with respect to Na-ion batteries. In this context, freestanding silicene, a graphene-silicene-graphene heterostructure, and a graphene-silicene superlattice are investigated for possible application in Na-ion batteries, using first-principles calculations. The calculated Na capacities of 954mAh/g for freestanding silicene and 730mAh/g for the graphenesilicene superlattice (10% biaxial tensile strain) are highly competitive and potentials of >0.3 V against the Na/Na potential exceed the corresponding value of graphite. In addition, the diffusion barriers are predicted to be <0.3 eV.

    Full Text Available Os agravos à saúde do trabalhador vêm, historicamente, acompanhando o crescimento econômico e a diversificação dos processos produtivos. O agronegócio expandiu-se nas últimas três décadas no estado de Mato Grosso e nele a intensificação das atividades do setor pecuário traduziu-se na instalação de frigoríficos, aumento de empregos formais e acidentes de trabalho. Este estudo propôs-se a caracterizar os acidentes de trabalho em indústrias frigoríficas do estado de Mato Grosso no período de 2000 a 2005, contextualizando-os com o mercado de trabalho e a inserção da mão de obra, através da utilização dos indicadores de acidentes de trabalho oriundos das Comunicações de Acidentes do Trabalho do Ministério da Previdência Social, dados da RAIS, do Ministério do Trabalho e Emprego, e da PNAD, do IBGE. Os resultados apontaram para o crescimento de postos de trabalho com expressiva rotatividade, diminuição do salário de admissão (de 2,2 para 2,0 salários mínimos e a maioria da mão de obra com baixa escolaridade. O setor frigorífico ocupou a segunda posição na estatística de doenças e acidentes de trabalho registrados no estado, cuja taxa de incidência cresceu de 41,2 para 46,5 acidentes de trabalho por mil trabalhadores, com maior incidência na faixa etária dos 18 aos 24 anos (49,8 acidentes/mil trabalhadores, atingindo principalmente os trabalhadores ocupados nas principais etapas do processo produtivo. Os resultados sugerem indícios de precarização do emprego e condições de trabalho na atividade frigorífica e insuficiência da ação de vigilância/fiscalização estatal no setor, bem como baixos investimentos dos empresários na saúde e segurança do trabalho.Historically, workers' health problems have been increasing as the economy grows and the productive processes diversify.

    2016-12-01

    In this study, MgO-templated carbon with different pore structures was investigated as a negative electrode material for Na-ion capacitors. With increasing the Brunauer-Emmett-Teller surface area, the irreversible capacity increased, and the coulombic efficiency of the 1st cycle decreased because of the formation of solid electrolyte interface layers. MgO-templated carbon annealed at 1000 °C exhibited the highest capacity and best rate performance, suggesting that an appropriate balance between surface area and crystallinity is imperative for fast Na-ion storage, attributed to the storage mechanism: combination of non-faradaic electric double-layer capacitance and faradaic Na intercalation in the carbon layers. Finally, a Na-ion capacitor cell using MgO-templated carbon and activated carbon as the negative and positive electrodes, respectively, exhibited an energy density at high power density significantly greater than that exhibited by the cell using a commercial hard carbon negative electrode.

    Full Text Available A formulação de políticas públicas que beneficiem a sociedade e que gerem pouco impacto ambiental é um dos grandes desafios dos gestores públicos. Aliar desenvolvimento econômico com manutenção de um ecossistema saudável torna essa tarefa mais árdua porque grande parte das ações realizadas pelo homem gera alterações no ambiente, principalmente quando se trata de abertura e manutenção de vias que envolvem, quase que, em sua totalidade a supressão da vegetação nativa, modificação da paisagem e fragmentação de habitats. No Jalapão, a abertura da rodovia TO 11O, que interliga os municípios tocantinenses de Mateiros e São Félix em meados da década de 1990 e a abertura dos ramais que interligam essa rodovia aos atrativos turísticos inseridos no interior do Parque Estadual do Jalapão e adjacencias, resultou na retirada de parte dos materiais (cascalho, areia e argila das cabeceiras das vertentes, ocasionando passivos ambientais, merecendo destaque o processo de assoreamento dos cursos d’água, tais como o córrego Carrapato e o Córrego Formiga. Dessa forma, o presente trabalho teve como objetivo diagnosticar os efeitos da expansão viária e analisar de qual forma o planejamento e gestão da malha viária interferem no manejo de áreas protegidas na região do Jalapão e, em especial, na TO 110. Os resultados da pesquisa indicaram um predomínio nos problemas associados aos grupos I (corpo estradal, grupo II (materiais de construção e instalações e grupo V (áreas ambientalmente sensíveis.

    Highlights: → In industrial sites located in natural hazard-prone areas technological accidents may be triggered by natural events, generating the so-called Na-Tech accidents. → In this paper, a qualitative screening methodology for assessing the earthquake Na-Tech risk has been developed with the aim of identifying which situations deserve a much more expensive Quantitative Risk Analysis. → The simple procedure developed, which summarizes in a suitable Key Hazard Indicator the Na-Tech risk level, has been validated by comparing its results with those of some Quantitative Risk Analyses involving also Na-Tech events and previously presented in the literature. - Abstract: Na-Tech (Natural and Technological) refers to industrial accidents triggered by natural events such as storms, earthquakes, flooding, and lightning. Herein, a qualitative methodology for the initial assessment of earthquake Na-Tech risk has been developed as a screening tool to identify which situations require a much more expensive Quantitative Risk Analysis (QRA). The proposed methodology, through suitable Key Hazard Indicators (KHIs), identifies the Na-Tech risk level associated with a given situation (i.e., a process plant located in a given territory), using the Analytical Hierarchy Process as a multi-criteria decision tool for the evaluation of such KHIs. The developed methodology was validated by comparing its computational results with QRA results that involved Na-Tech events previously presented in literature.

  14. Slow [Na+]i dynamics impacts arrhythmogenesis and spiral wave reentry in cardiac myocyte ionic model.

    Krogh-Madsen, Trine; Christini, David J

    2017-09-01

    Accumulation of intracellular Na + is gaining recognition as an important regulator of cardiac myocyte electrophysiology. The intracellular Na + concentration can be an important determinant of the cardiac action potential duration, can modulate the tissue-level conduction of excitation waves, and can alter vulnerability to arrhythmias. Mathematical models of cardiac electrophysiology often incorporate a dynamic intracellular Na + concentration, which changes much more slowly than the remaining variables. We investigated the dependence of several arrhythmogenesis-related factors on [Na + ] i in a mathematical model of the human atrial action potential. In cell simulations, we found that [Na + ] i accumulation stabilizes the action potential duration to variations in several conductances and that the slow dynamics of [Na + ] i impacts bifurcations to pro-arrhythmic afterdepolarizations, causing intermittency between different rhythms. In long-lasting tissue simulations of spiral wave reentry, [Na + ] i becomes spatially heterogeneous with a decreased area around the spiral wave rotation center. This heterogeneous region forms a functional anchor, resulting in diminished meandering of the spiral wave. Our findings suggest that slow, physiological, rate-dependent variations in [Na + ] i may play complex roles in cellular and tissue-level cardiac dynamics.

    Full Text Available A educação física escolar deve proporcionar experiências aos alunos para o seu desenvolvimento integral. As aulas muitas vezes são reduzidas ao ensino de esportes tradicionais, o que limita o repertório de movimentos dos alunos. Dessa forma o presente estudo de revisão objetiva problematizar o atletismo no ambiente escolar e propor possibilidades pedagógicas para seu ensino. Nesta pesquisa propomos tratar o ensino do atletismo na escola, caracterizando-o pelo seu repertório de movimentos que são naturais ao ser humano, como correr, saltar e lançar, o que possibilita maior praticidade em sua aplicação pedagógica, porém essas possibilidades não são consideradas no ambiente educacional. Diante dos dados encontrados, sugerimos que esse esporte seja abordado de forma multidimensional no ambiente escolar contextualizando-o à visão de algumas correntes teóricas. Nessa perspectiva do esporte educacional, o atletismo pode, assim como deve ser trabalhado nas aulas de educação física como instrumento pedagógico de ensino e auxiliar na formação do aluno de forma global.

    Full Text Available A inclusão de alunos com necessidades educacionais especiais no ensino regular depende da preparação da comunidade escolar para promover a participação de todos os alunos. Foi objetivo deste estudo conhecer, do ponto de vista do professor do ensino fundamental da rede pública municipal, as estratégias pedagógicas que utilizavam para a inclusão de crianças com deficiência na classe comum. Para isso foram realizadas entrevistas semiestruturadas individuais e, posteriormente, grupais com 11 professores de cinco escolas, um representante do Centro de Formação e Acompanhamento à Inclusão e um coordenador pedagógico. As entrevistas foram gravadas e transcritas. Após diversas leituras foi possível identificar como temáticas principais: sentidos e imaginários do professor sobre a deficiência, formação do professor para efetivação do processo de inclusão, bem como a utilização de estratégias pedagógicas diferenciadas e formação de rede de apoio na escola. Os entrevistados utilizavam estratégias gerais como aula expositiva, debates, e específicas como: avaliação dos alunos, adaptação do material, atividades em duplas, parceria com o professor da sala de apoio e acompanhamento à inclusão. Parte dos entrevistados trouxe uma visão com relação aos alunos com deficiência permeada de possibilidades, acreditando no potencial de aprendizagem dos mesmos, enquanto para outros, o discurso centrou-se, sobretudo, na impossibilidade da aprendizagem. Os docentes identificaram a necessidade de apoio institucional para seu trabalho, incluindo possibilidades de formação a partir das demandas cotidianas. Responder às necessidades levantadas é parte dos desafios para implementar a Educação Inclusiva na perspectiva da Educação para Todos, para a efetivação dos direitos de crianças com necessidades educacionais especiais.Including students with special needs in regular education requires preparation by the school community

    Full Text Available INTRODUÇÃO: A letalidade da malária na região extra-amazônica é cerca de 80 vezes maior do que na Amazônia, que concentra 99,8% dos casos do país. Em áreas de transmissão de dengue, como o Rio de Janeiro, o atraso no diagnóstico e tratamento da malária dos pacientes com febre, provenientes de áreas endêmicas de malária, pode ser, entre outros fatores, devido à confusão entre o diagnóstico das duas doenças pelos generalistas da rede de assistência médica. Neste trabalho, apresentamos as consequências do atraso diagnóstico em três pacientes com malária por Plasmodium falciparum; P. malariae e P. vivax, que, após o périplo habitual para tratamento de dengue, procuraram a nossa instituição onde foram corretamente diagnosticados e submetidos aos tratamentos adequados. MÉTODOS: Descrição de três casos de malária diagnosticada tardiamente e encaminhados ao IPEC/ FIOCRUZ, entre os anos de 2007 e 2008. RESULTADOS: uma brasileira proveniente de Moçambique, primo-infectada por P. falciparum, com malária diagnosticada após 6 dias do início da febre, morreu com malária cerebral e choque. Outro paciente com malária por P. malariae teve um curso grave e prolongado, mas ficou curado após o tratamento específico. A terceira paciente diagnosticada tardiamente apresentou malária por P. vivax adquirida na região de Mata Atlântica no Estado do Rio. CONCLUSÕES: Os profissionais de saúde do Rio devem ser treinados para aperfeiçoar a vigilância e o tratamento oportuno da malária e evitar desfechos mórbidos e fatais. Sugere-se que uma investigação de focos de malária autóctone em áreas de mata no estado seja realizada.INTRODUCTION: The mortality of malaria in the extra-Amazon region is about 80 times higher than in the Amazon region, where malaria is concentrated (99.8% of cases.

    A study of 23 Na via the 22 Ne(p,γ) 23 Na and 23 Na(γ,γ) 23 Na reactions is presented. Only a limited number of resonances has been studied, selected on the basis of strong excitation of the lowest levels of which the spin was unknown. As a result the spins are now known of all levels of 23 Na with excitation energies up to 7 MeV, except for a few high-spin states which are too weakly excited in the decay of the known 22 Ne(p,γ) resonances. The mean lifetimes of the 23 Na levels at 4.43 and 7.89 MeV were found to be 350±70 and 220±17 attoseconds (1 attosecond = 10 -18 seconds) respectively. 97 refs.; 22 figs.; 12 tabs

    2017-07-01

    The popularity of tattoos has increased tremendously in the last 10 yr particularly among athletes and military personnel. The tattooing process involves permanently depositing ink under the skin at a similar depth as eccrine sweat glands (3-5 mm). The purpose of this study was to compare the sweat rate and sweat Na concentration of tattooed versus nontattooed skin. The participants were 10 healthy men (age = 21 ± 1 yr), all with a unilateral tattoo covering a circular area at least 5.2 cm. Sweat was stimulated by iontophoresis using agar gel disks impregnated with 0.5% pilocarpine nitrate. The nontattooed skin was located contralateral to the position of the tattooed skin. The disks used to collect sweat were composed of Tygon® tubing wound into a spiral so that the sweat was pulled into the tubing by capillary action. The sweat rate was determined by weighing the disk before and after sweat collection. The sweat Na concentration was determined by flame photometry. The mean sweat rate from tattooed skin was significantly less than nontattooed skin (0.18 ± 0.15 vs 0.35 ± 0.25 mg·cm·min; P = 0.001). All 10 participants generated less sweat from tattooed skin than nontattooed skin and the effect size was -0.79. The mean sweat Na concentration from tattooed skin was significantly higher than nontattooed skin (69.1 ± 28.9 vs 42.6 ± 15.2 mmol·L; P = 0.02). Nine of 10 participants had higher sweat Na concentration from tattooed skin than nontattooed skin, and the effect size was 1.01. Tattooed skin generated less sweat and a higher Na concentration than nontattooed skin when stimulated by pilocarpine iontophoresis.

    This is one section of the toroidal-field spectrometer magnet of experiment NA4 (deep inelastic muon scattering), shown here during the installation period and later located in the North Area of the SPS. To see all 4 sections, select 7709201. Igor Savin from Dubna looks at what his lab had provided: the huge iron disks were machined at and provided by Dubna. Multi-Wire Proportional Chambers were installed in the gaps between the packs of 4 disks. When the beam from the SPS struck the target (to the right in this picture), the iron would quickly stop the hadronic shower, whilst the muons would go on, performing oscillations in the toroidal field. NA4 was a CERN-Dubna-Munich-Saclay (later also Bologna) collaboration, spokesman: Carlo Rubbia.

    NA60 is taking data with proton and heavy-ion beams at the CERN SPS. Although building up on previous experiments, the dimuon physics programme of NA60 places very demanding requirements on its new detectors, in terms of radiation tolerance, granularity and read-out electronics speed. We start by comparing dimuon detection strategies in NA60 with those of previous experiments. We then describe the new detectors used in NA60, placing particular emphasis on their technological pioneering aspects as well as on their contributions to the overall physics performance of the experiment

In order to complete previous studies of this reaction, radioactive $^{22}$Na targets of high purity are required. We ask for support to fabricate these targets via the implantation technique at ISOLDE GPS (off—line mode) using $^{22}$Na nuclides in an Al matrix produced in Nov. 1990 at the PSI (Zürich). The $^{22}$Na nuclides are released and ionized in a surface ionisation source, mass-analyzed at ISOLDE GPS, and implanted in a Ni-Ta backing and a C—foil in a special implantation setup.

    The current Hydrogen based energy infrastructure required a high energy density consumer friendly hydrogen storage media. Although the desired goals for the hydrogen fueled vehicular transport has not yet met by any hydrogen storage material, complex Sodium Alanate is said to be a promising candidate under this demand due to its high hydrogen storage capacity and the thermodynamically permissible reversible hydrogen storage capacity. However its poor sorption behavior under moderate conditions (NaAlH 4 →Na 3 AlH 6 ; 3.7 wt % vs 50 hrs at ∼170 C and Na 3 AlH 6 →NaH; 1.85 wt % vs 30 hrs at ∼220 C) urges their limited uses in ages. But these limitations can be removed by using catalysts particularly transition elements but the location of catalyst in NaAlH 4 matrix and the possible mechanism is not yet clearly understood. The aim of the present investigation is to improve the overall sorption characteristics of NaAlH 4 by a new light weighted high surface area (1315 sq mtr/gm) material (CNT) admixing and to obtain a best doping level to NaAlH 4 . So far only Ti has been attempted as a suitable catalyst. It is believed that the high surface area of CNT can provide an additional solid-gas (H 2 ) surface/interface and it can produce thermal contact between grains (thermal conductivity Kth of MWCNT: 3000 w/k and Kth of NaAlH 4 : 0.32 w/k) for stimulating their thermally activated dissociation in NaAlH 4 . In parallel with this approach XRD of NaAlH 4 reveals that there was no change in lattice structure after doping by CNT, SEM picture depicts that CNT precipitation in grain surfaces. Catalytic concentration of various mole % of x values finds that x = 8 is the best doping level as it gives 3.3 wt % of hydrogen within 2 hrs. The comparative sorption behavior with Ti:NaAlH 4 also shows CNTs as an optimum alternative catalyst to NaAlH 4 and besides this CNT doped desorbed ingredients shown good re-hydrogenation behavior(3.7 wt % at 8. cycle and 4.2 wt % maximum at

    Perovskite-type NaTaO 3 derived from a sol-gel synthesis exhibited a larger surface area and a remarkably higher photocatalytic activity in water splitting than the solid-state synthesized NaTaO 3 . The sol-gel and solid-state NaTaO 3 had different crystalline structures of monoclinic P2/m and orthorhombic Pcmn, respectively. Diffuse reflectance spectra showed that the sol-gel specimen had a slightly larger band gap. The band structure analysis revealed an indirect band gap for the sol-gel NaTaO 3 , contrary to the direct band gap of the solid-state one. The difference in the electronic structure and surface area explained the higher photocatalytic activity of the sol-gel NaTaO 3

Foucault rozwija w nim koncepcję archeologii wiedzy – metody analizy historycznych dyskursów, którą zaprezentuje w sześć lat później w książce o tym właśnie tytule. Artykuł powstał na kanwie pytania wybranego przez autora spośród zadanych mu przez redakcję „Esprit”, które dotyczyło możliwości pojęciowego opracowania przymusu systemu dyskursywnego przy jednoczesnym zaakcentowaniu nieciągłości w jego obrębie a tym samym możliwości twórczego działania w historii ducha.

    Full Text Available The goal of the empirical study is to describe critical areas of primary mathematics as can be found from the Czech Grade 8 pupils’ results in TIMSS 2007 and to identify possible causes of their difficulty for pupils. In the first part, a research background is briefly given – international comparative research in mathematics and possibilities of the secondary analyses of its data. The second part describes methodology in detail. We analysed data from so called TIMSS almanacs (results of Czech pupils at the level of concrete mathematical items from TIMSS and answers of the teacher questionnaire. To interpret possible causes we also used curricular documents and the analysis of the apparently most used primary mathematics textbooks. We set up a criterion for deciding whether the Czech pupils’ results for the given item is below their standard which we determined by comparing their average success rate with that of the international sample. Thus so called weak and very weak items were identified. They were divided into three areas which can be considered critical areas for Czech pupils: Algebra (with subareas of Functions, Substitution, Equations and inequalities, Expressions, Sequences, Shapes and solids. For each of the areas, weak and very weak items are presented together with their results and an outline of the nature of their difficulty for Czech pupils and possible causes of Czech pupils’ failure to solve them. It transpires that it is necessary to get a deeper insight into the nature of problems by clinical interviews with pupils. This will be a topic of further articles.

    O objetivo do presente trabalho foi avaliar a sobrevivência de árvores leguminosas plantadas para recuperar áreas degradadas e as produtividades de milho e mandioca num sistema tradicional de agricultura de derruba-e-queima. Foram utilizados os espaçamentos 1 m x 1 m, 2 m x 1 m e 2 m x 2 m para plantio de Acacia angustissima, Clitoria racemosa, Inga edulis e Acacia mangium. A espécie Sclerolobium paniculatum foi plantada somente no espaçamento 2 m x 1 m. Na condução do experimento, o milho permaneceu no experimento nos primeiros quatro meses e considerado como monocultura, produziu 1.890 +/- 32 kg ha-1. A sobrevivência das árvores, plantadas junto com milho e na mesma época da mandioca, não sofreu interferência negativa das culturas agrícolas. Independente do espaçamento, as árvores não causaram impacto negativo no peso seco das raízes de mandioca. Quanto a densidade de árvores observou-se tendência de aumento do peso seco das raízes de mandioca com a diminuição do número de árvores plantadas por hectare. Os resultados evidenciam a possibilidade de se manter a produtividade agrícola associada ao plantio de árvores. Entretanto, a opção pelo espaçamento 1 m x 1 m deve ser cuidadosamente analisada quando o objetivo principal for a produção de alimentos.

    This paper is the third in a series of reviews published in this issue resulting from the University of California Davis Cardiovascular Symposium 2014: Systems approach to understanding cardiac excitation–contraction coupling and arrhythmias: Na+ channel and Na+ transport. The goal of the symposium was to bring together experts in the field to discuss points of consensus and controversy on the topic of sodium in the heart. The present review focuses on cardiac Na+/Ca2+ exchange (NCX) and Na+/K+-ATPase (NKA). While the relevance of Ca2+ homeostasis in cardiac function has been extensively investigated, the role of Na+ regulation in shaping heart function is often overlooked. Small changes in the cytoplasmic Na+ content have multiple effects on the heart by influencing intracellular Ca2+ and pH levels thereby modulating heart contractility. Therefore it is essential for heart cells to maintain Na+ homeostasis. Among the proteins that accomplish this task are the Na+/Ca2+ exchanger (NCX) and the Na+/K+ pump (NKA). By transporting three Na+ ions into the cytoplasm in exchange for one Ca2+ moved out, NCX is one of the main Na+ influx mechanisms in cardiomyocytes. Acting in the opposite direction, NKA moves Na+ ions from the cytoplasm to the extracellular space against their gradient by utilizing the energy released from ATP hydrolysis. A fine balance between these two processes controls the net amount of intracellular Na+ and aberrations in either of these two systems can have a large impact on cardiac contractility. Due to the relevant role of these two proteins in Na+ homeostasis, the emphasis of this review is on recent developments regarding the cardiac Na+/Ca2+ exchanger (NCX1) and Na+/K+ pump and the controversies that still persist in the field.

Foram avaliados pólen e esporos de plantas terrestres juntamente com as partículas de carvão. Dois estágios, no desenvolvimento paleoambiental, foram estabelecidos com respeito ao desenvolvimento da vegetação. Um estágio mais antigo é caracterizado pela distribuição limitada das florestas ripárias e predomínio de campo nas condições de clima mais seco. Quantidade notável de partículas de carvão encontradas nas amostras deste estágio sugere ocorrência de queimadas locais ou regionais durante um clima seco. No estágio mais novo, a expansão das ripárias emresposta ao aumento das precipitações atmosféricas ocorreu. Pólen de plantas cultivadas, daninhas e invasoras, encontrado nos sedimentos, indica o desenvolvimento da agricultura neste estágio. Maior freqüência de partículas de carvão em mesmos sedimentos provavelmenteindique ocorrência de queimadas locais associadas ao desmatamento da região. The samples from two profiles of flood plain deposits of the Paraná River were studied. One sample at the depth of 1.95 m was dated by 14C as 1,700 ± 70 yr BP. Palynological data and charcoal particles were obtained from fluvial sediments and paleosoil. Two principal stages in paleoenvironmental development were established. The early stage is characterized by the limited distribution of riparian forests and predominance of mesophyllous grassland under a condition of relatively dry climate. The deposition of charcoal particles in such predominant quantity was the result of local or regional burns.During the more recent stage, a natural enlargement of riparian forests occurred in conjunction with an increase in rainfall. Land use of that region may be confirmed by relatively frequent presence of

    We report the first case of an intraoperative radiotherapy (IORT) in a patient with recurrent glioblastoma multiforme (GBM) who was followed up with a novel magnetic resonance imaging (MRI) method - 23 Na-MRI - in comparison to a standard contrast-enhanced 1 H-MRI and 18 F-FET-PET. A 56-year-old female patient with diagnosed GBM in July 2012 underwent tumor resection, radiochemotherapy, and three cycles of chemotherapy. After a relapse, 6 months after the initial diagnosis, an IORT was recommended which was performed in March 2013 using the INTRABEAM system (Carl Zeiss Meditec AG, Germany) with a 3-cm applicator and a surface dose of 20 Gy. Early post-operative contrast-enhanced and 1-month follow-up 1 H-MRI and a 18 F-FET-PET were performed. In addition, an IRB-approved 23 Na-MRI was performed on a 3.0-T MR scanner (MAGNETOM TimTrio, Siemens Healthcare, Germany). After re-surgery and IORT in March 2013, only a faint contrast enhancement but considerable surrounding edema was visible at the medio-posterior resection margins. In April 2013, new and progressive contrast enhancement, edema, 23 Na content, and increased uptake in the 18 F-FET-PET were visible, indicating tumor recurrence. Increased sodium content within the area of contrast enhancement was found in the 23 Na-MRI, but also exceeding this area, very similar to the increased uptake depicted in the 18 F-FET-PET. The clearly delineable zone of edema in both examinations exhibits a lower 23 Na content compared to areas with suspected proliferating tumor tissue. 23 Na-MRI provided similar information in the suspicious area compared to 18 F-FET-PET, exceeding conventional 1 H-MRI. Still, 23 Na-MRI remains an investigational technique, which is worth to be further evaluated. (orig.)

    NA61/SHINE (SPS Heavy Ion and Neutrino Experiment) is a multi-purpose experimental facility to study hadron production in hadron-proton, hadron-nucleus and nucleus-nucleus collisions at the CERN Super Proton Synchrotron. It recorded the first physics data with hadron beams in 2009 and with ion beams (secondary 7Be beams) in 2011. NA61/SHINE has greatly profited from the long development of the CERN proton and ion sources and the accelerator chain as well as the H2 beamline of the CERN North Area. The latter has recently been modified to also serve as a fragment separator as needed to produce the Be beams for NA61/SHINE. Numerous components of the NA61/SHINE set-up were inherited from its predecessors, in particular, the last one, the NA49 experiment. Important new detectors and upgrades of the legacy equipment were introduced by the NA61/SHINE Collaboration.

    Research interest in Na-ion batteries has increased rapidly because of the environmental friendliness of sodium compared to lithium. Throughout this Perspective paper, we report and review recent scientific advances in the field of negative electrode materials used for Na-ion batteries. This paper sheds light on negative electrode materials for Na-ion batteries: carbonaceous materials, oxides/phosphates (as sodium insertion materials), sodium alloy/compounds and so on. These electrode materials have different reaction mechanisms for electrochemical sodiation/desodiation processes. Moreover, not only sodiation-active materials but also binders, current collectors, electrolytes and electrode/electrolyte interphase and its stabilization are essential for long cycle life Na-ion batteries. This paper also addresses the prospect of Na-ion batteries as low-cost and long-life batteries with relatively high-energy density as their potential competitive edge over the commercialized Li-ion batteries.

    Full Text Available It is aimed to show our position on the (no need of the civil action filing the record in property, subject of the registration of the demand that is intended to be obliged to institute legal nature reserve area, making use, therefore, of the adoption of hypothetical deductive method, combined with the execution of theoretical and documentary research. Legal Nature Reserve is understood as the area of rural land that can not suffer human intervention by deforestation and exploitation of its resources. Its institution and subsequent registration with the Rural Environmental Registry is an propter rem obligation, given the tracking of it and the attachment to the holder of real right. It must be obeyed even that forests or other type of vegetation no longer exist in the property, which thus externalizes its institution being a mandatory requirement for regular registration of the property, making it impossible to any claim of its ignorance, because it clings to the ownership of the property, passing to new owners, they being able to be charged regardless of their proceeding.

    Full Text Available The use of fragrances to attract males of Euglossinae bees has been an important tool to increase the knowledge of the group. In the Northeastern of Brazil, studies on euglossine bees are still uncommon, mainly in urban areas. The goals of this study are to identify the Euglossinae species composition, to know the diversity and the community structure of Euglossinae species, verify their preferences for different fragrances and evaluate the phenology of these species, in two Atlantic Forest fragments of the city of João Pessoa, Paraíba state, Brazil. Bees were sampled at 15 days intervals, over the course of one year, from 8:00 to 17:00 hours, through the use of traps baited with seven types of fragrances. In both areas, 1082 individuals belonging to nine species were sampled. None significant difference of diversity and relative abundance of bees between fragments were observed. Eucalyptol was the most attractive fragrance. Bees were more abundant between 8:00 and 9:00 AM. Visits to the fragrances were more frequent from the middle of dry season to the beginning of the rainy season and positively correlated with the monthly mean temperature. Most species of bees visited all the baits over the year, but the number of attracted males was highest in April.

    Full Text Available O bullying é uma forma de violência presente nas escolas e o termo é utilizado para caracterizar todas as formas de agressões repetitivas psicológicas e físicas, direta ou indiretamente. Esta violência causa sofrimentos, intimidação e medo, sempre numa relação de poder entre pares. Esta pesquisa trata de um estudo do bullying escolar: o que é, como surgiu, como identificá-lo e sua caracterização, conseqüências, causas, o papel da escola, de professores e pais e uma proposta prática que pode ser adotada para sua prevenção e contenção. O objetivo é organizar materiais para leitura dos atores educacionais para uma possível reflexão, através de pesquisas bibliográficas. Esta violência é grave e deveria ser tratada como saúde pública, devido às conseqüências que traz, como queda na aprendizagem, na autoestima e em casos mais graves, até o suicido e outras tragédias. A escola necessita atentar para esse tipo de violência, revendo suas ações em todos os momentos, tendo um olhar integral e diferenciado em relação aos alunos. É fundamental que o bullying não seja tratado como brincadeira de criança e para ser identificado e combatido é necessária uma ação entre a família e todos da escola, que pode ser desenvolvida através de projetos que ajudem a apontar caminhos para a solução do problema. Tais ações devem ser pautadas por constantes debates e reflexões, nas quais o aluno se torne o protagonista. Não existem fórmulas prontas, pois a intervenção deve ser feita através da realidade de cada escola.

    1978-02-01

    The purpose of this study is to provide a contribution to the understanding of the sodium - carbon - oxygen and sodium - hydrogen - oxygen ternary systems in the sodium rich corner. In order to do this the Na-NaH-Na 2 O-NaOH phase diagram was completed and the Na-Na 2 O-Na 2 CO 3 -C phase diagram was outlined. This work is made up of two parts. The first is devoted to a critical literature survey essential to establish correct phase diagrams. The second is an experimental study followed by a discussion collating our finding to the literary data.

    Full Text Available O crescimento foliar e a acumulação de matéria seca durante o estabelecimento da ervilha (Pisum sativum L., var. Ballet, do milho (Zea mays L., var. Lorena e do girassol (Helianthus annuus L., var. Flora-sol foram estudados em função da temperatura e do teor de água num solo Pmg(Évora e num Cb (Lisboa, entre Junho de 1995 e Novembro de 1996. Mediu-se a temperatura do solo a 2 e 4 cm de profundidade, a temperatura do ar e a humidade do solo. A área foliar das plântulas foi estimada a partir de medições do comprimento e da largura de cada folha. A acumulação de matéria seca foi avaliada pela pesagem da parte aérea das plântulas após secagem em estufa. Os dados foram analisados com base no conceito de tempo térmico. Para teores de humidade superiores a 50% da capacidade utilizável de cada solo, a área foliar durante o estabelecimento da ervilha e do milho aumentou linearmente com a temperatura acumulada, enquanto que a do girassol aumentou exponencialmente durante o mesmo período. A relação entre a acumulação de matéria seca de qualquer das culturas e a temperatura acumulada foi exponencial. O tipo de solo influenciou significativamente o “início da expansão foliar” da ervilha e do girassol, a “taxa térmica de expansão foliar” do milho e a acumulação de matéria seca da ervilha e do milho. O “início da expansão foliar” da ervilha ocorreu mais cedo no solo Cb enquanto que o do girassol ocorreu mais cedo no solo Pmg. A expansão foliar do milho foi mais rápida no solo Pmg. A acumulação de matéria seca da ervilha foi mais rápida no solo Cb, enquanto que a do girassol foi mais rápida no solo Pmg. Em ambos os solos, baixos teores de humidade afectaram negativamente a expansão da área foliar e a acumulação de matéria seca.Leaf area expansion and accumulation of dry matter during the establishment of pea (Pisum sativum L., var.

Foi detectada, porém, a presença de Salmonella Enteritidis em um Rattus norvegicus e em um Didelphis albiventris. Nas condições em que esse estudo foi realizado, os nossos resultados indicam que ratos e gambás que habitam granjas avícolas não constituem um fator de risco na transmissão de Trichinella e de Leptospira. A detecção de Salmonella Enteritidis tanto em ratos quanto em gambás, porém, sugere a necessidade de aplicar medidas profiláticas em granjas avícolas para maior controle desse agente.

Foram verificadas diferenças significativas entre as dimensões dos dois estágios, embora não se tenha encontrado uma diferença significativa entre as dietas, apesar de se ter observado uma preferência diferenciada por itens planctônicos. Os resultados sugerem que a partilha de recursos alimentares está relacionada não só com a morfologia e ocupação de diferentes microhábitats, mas também ao comportamento alimentar dos girinos. A relevância de itens importantes para a dieta natural dos girinos de S. angrensis, especialmente as algas diatomáceas e filamentosas, revela a importância da comunidade perifítica para a conservação desta espécie de anuro na Mata Atlântica.

    Full Text Available A terapia da linguagem na afasia foi estudada em 15 pacientes, 8 do sexo masculino e 7 do sexo feminino; a idade variou de menos de 10 anos a mais de 50 anos; em 11 casos a afasia era sequela de acidente vascular cerebral e, em 4, de traumatismo crânio-encefálico. Quanto ao tipo de afasia, 5 pacientes apresentavam déficits predominantemente de expressão e 10 apresentavam déficits receptivos e expressivos em graus equiparáveis. Em 6 casos a terapia foi iniciada dentro dos 3 primeiros meses de instalação do quadro; nos restantes foi iniciada mais tardiamente. Dos 15 pacientes, 11 apresentaram evolução satisfatória, a qual não depndeu do grau de afasia, do tipo de afasia, da idade do paciente, do tipo de patologia e do intervalo entre a instalação do quadro afásico e o início da terapia. A terapia da linguagem no paciente afásico é efetiva, o prognóstico não pode ser feito a priori. Somente a evolução do caso com sua retestagem criteriosa poderá dar dados realmente úteis para se falar em evolução.

  10. Extracellular Na+ levels regulate formation and activity of the NaX/alpha1-Na+/K+-ATPase complex in neuronal cells.

    Full Text Available MnPO neurons play a critical role in hydromineral homeostasis regulation by acting as sensors of extracellular sodium concentration ([Na+]out. The mechanism underlying Na+-sensing involves Na+-flow through the NaX channel, directly regulated by the Na+/K+-ATPase α1-isoform which controls Na+-influx by modulating channel permeability. Together, these two partners form a complex involved in the regulation of intracellular sodium ([Na+]in. Here we aim to determine whether environmental changes in Na+ could actively modulate the NaX/Na+/K+-ATPase complex activity.We investigated the complex activity using patch-clamp recordings from rat MnPO neurons and Neuro2a cells. When the rats were fed with a high-salt-diet, or the [Na+] in the culture medium was increased, the activity of the complex was up-regulated. In contrast, drop in environmental [Na+] decreased the activity of the complex. Interestingly under hypernatremic condition, the colocalization rate and protein level of both partners were up-regulated. Under hyponatremic condition, only NaX protein expression was increased and the level of NaX/Na+/K+-ATPase remained unaltered. This unbalance between NaX and Na+/K+-ATPase pump proportion would induce a bigger portion of Na+/K+-ATPase-control-free NaX channel. Thus we suggest that hypernatremic environment increases NaX/Na+/K+-ATPase α1-isoform activity by increasing the number of both partners and their colocalization rate, whereas hyponatremic environment down-regulates complex activity via a decrease in the relative number of NaX channels controlled by the pump.

    Full Text Available O presente artigo sobre o artesanato e a Terceira Idade, pesquisa realizada em 2011, teve como metodologia o Estudo de Caso do tipo etnográfico. A metodologia de investigação ocorreu por meio de entrevistas semiestruturadas, orais e transcritas, observação e fotografias dos artesanatos em locais de venda e nas residências dos artesãos. Os sujeitos da pesquisa foram: a presidente da Associação da Casa do Artesão de Sinop-MT e oito artesãos. O objetivo foi mostrar a importância do artesanato como atividade educacional e como produtora de autonomia e autoria para os artesãos da Terceira Idade, motivados em realizar este trabalho nesta fase da vida. Para o embasamento teórico utilizou-se obras de Paulo Freire, Moacir Gadotti e sobre a Terceira Idade a coleção de Vivaidade com a organizadora Anita Liberalesso Neri. A análise das entrevistas mostrou que o artesanato traz autonomia educacional quando o idoso busca sozinho aprender sobre o objeto a ser realizado, assim como autonomia financeira, uma vez que a venda do artesanato proporciona certa independência econômica. Em relação ao sentimento de autoria das peças criadas constatou-se muita satisfação e realização, o que motiva a continuar sendo úteis e produtivos na Terceira Idade com muita criatividade. Palavras-chave: educação; terceira idade; artesanato; autonomia; autoria.

  12. Transgenerational soil-mediated differences between plants experienced or naïve to a grass invasion.

    Invasive species may undergo rapid change as they invade. Native species persisting in invaded areas may also experience rapid change over this short timescale relative to native populations in uninvaded areas. We investigated the response of the native Achillea millefolium to soil from Holcus lanatus-invaded and uninvaded areas, and we sought to determine whether differential responses between A. millefolium from invaded (invader experienced) and uninvaded (invader naïve) areas were mediated by soil community changes. Plants grown from seed from experienced and naïve areas responded differently to invaded and uninvaded soil with respect to germination time, biomass, and height. Overall, experienced plants grew faster and taller than their naïve counterparts. Naïve native plants showed negative feedbacks with their home soil and positive feedbacks with invaded soil; experienced plants were less responsive to soil differences. Our results suggest that native plants naïve to invasion may be more sensitive to soil communities than experienced plants, consistent with recent studies. While differences between naïve and experienced plants are transgenerational, our design cannot differentiate between differences that are genetically based, plastic, or both. Regardless, our results highlight the importance of seed source and population history in restoration, emphasizing the restoration potential of experienced seed sources.

    The Na(+), K(+)-adenosine triphosphatase (ATPase) maintains the electrochemical gradients of Na(+) and K(+) across the plasma membrane--a prerequisite for electrical excitability and secondary transport. Hitherto, structural information has been limited to K(+)-bound or ouabain-blocked forms. We present the crystal structure of a Na(+)-bound Na(+), K(+)-ATPase as determined at 4.3 Å resolution. Compared with the K(+)-bound form, large conformational changes are observed in the α subunit whereas the β and γ subunit structures are maintained. The locations of the three Na(+) sites are indicated with the unique site III at the recently suggested IIIb, as further supported by electrophysiological studies on leak currents. Extracellular release of the third Na(+) from IIIb through IIIa, followed by exchange of Na(+) for K(+) at sites I and II, is suggested.

    In recent years, materials such as lead, concrete and iron have been studied for use as shielding for ionizing radiations of different energies in radiative installations. In the radiodiagnosis area, lead and barite are the most used materials as shielding. However, for beams of low energy X-radiation, such as in mammography and dentistry, the gypsum material may be used. This study aims to verify the feasibility of the use of gypsum as shielding for low-energy X-ray using standardized dental X-ray beams in a metrology laboratory. The project will allow a better understanding in the study of gypsum used as shielding, certifying its use as a good attenuator for low-energy X-ray.

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

    Full Text Available Sodium carbonate (Na2CO3, sodium nitrate (NaNO3, and sodium chloride (NaCl were chosen as the precursors to prepare the Na salts deposited Mn-Ce/TiO2 catalysts through an impregnation method. The influence of Na on the performance of the Mn-Ce/TiO2 catalyst for low-temperature selective catalytic reduction of NOx by NH3 was investigated. Experimental results showed that Na salts had negative effects on the activity of Mn-Ce/TiO2 and the precursors of Na salts also affected the catalytic activity. The precursor Na2CO3 had a greater impact on the catalytic activity, while NaNO3 had minimal effect. The characterization results indicated that the significant changes in physical and chemical properties of Mn-Ce/TiO2 were observed after Na was doped on the catalysts. The significant decreases in surface areas and NH3 adsorption amounts were observed after Na was doped on the catalysts, which could be considered as the main reasons for the deactivation of Na deposited Mn-Ce/TiO2.

    2011-01-01

    The NA62 experiment should start collecting its first data (technical run) in a little over one year. At the heart of the experiment is the Gigatracker, a newly conceived silicon pixel detector, whose job is to measure the arrival time and the position of the incoming beam particles. The demonstration detector has recently shown a time resolution of 175 picoseconds, an unprecedented record in the field of silicon pixel detectors.   The Gigatracker prototype. A 115 metre long vacuum tank, a brand new set of detectors surrounding it and an extremely rare decay to study: this is the new NA62 detector, foreseen to be installed in the SPS North Area in 2012. “We will study a very rare decay of the K+. Such a decay is sensitive to contributions coming from new particles and therefore represents a powerful way of searching for new physics, complementary to the direct approach of the LHC detectors,” explains Augusto Ceccucci, NA62 spokesperson.

    The SEMATECH Berkeley Actinic Inspection Tool (AIT) is an EUV-wavelength mask inspection microscope designed for direct aerial image measurements, and pre-commercial EUV mask research. Operating on a synchrotron bending magnet beamline, the AIT uses an off-axis Fresnel zoneplate lens to project a high-magnification EUV image directly onto a CCD camera. We present the results of recent system upgrades that have improved the imaging resolution, illumination uniformity, and partial coherence. Benchmarking tests show image contrast above 75% for 100-nm mask features, and significant improvements and across the full range of measured sizes. The zoneplate lens has been replaced by an array of user-selectable zoneplates with higher magnification and NA values up to 0.0875, emulating the spatial resolution of a 0.35-NA 4 x EUV stepper. Illumination uniformity is above 90% for mask areas 2-(micro)m-wide and smaller. An angle-scanning mirror reduces the high coherence of the synchrotron beamline light source giving measured σ values of approximately 0.125 at 0.0875 NA

    23 Na-MRI has been proposed as a potential imaging biomarker for the assessment of tumor viability and the evaluation of therapy response but has not yet been evaluated in patients with lung cancer. We aimed to assess the feasibility of 23 Na-MRI in patients with lung cancer. Three patients with stage IV adenocarcinoma of the lung were examined on a clinical 3 Tesla MRI system (Magnetom TimTrio, Siemens Healthcare, Erlangen, Germany). Feasibility of 23 Na-MRI images was proven by comparison and fusion of 23 Na-MRI with 1 H-MR, CT and FDG-PET-CT images. 23 Na signal intensities (SI) of tumor and cerebrospinal fluid (CSF) of the spinal canal were measured and the SI ratio in tumor and CSF was calculated. One chemonaive patient was examined before and after the initiation of combination therapy (Carboplatin, Gemcitabin, Cetuximab). All 23 Na-MRI examinations were successfully completed and were of diagnostic quality. Fusion of 23 Na-MRI images with 1 H-MRI, CT and FDG-PET-CT was feasible in all patients and showed differences in solid and necrotic tumor areas. The mean tumor SI and the tumor/CSF SI ratio were 13.3 ± 1.8 x 103 and 0.83 ± 0.14, respectively. In necrotic tumors, as suggested by central non-FDG-avid areas, the mean tumor SI and the tumor/CSF ratio were 19.4 x 103 and 1.10, respectively. 23 Na-MRI is feasible in patients with lung cancer and could provide valuable functional molecular information regarding tumor viability, and potentially treatment response.

    The production of Na 2 + ions by off-resonant laser excitation in the 5800-6200A region mainly results from two-photon absorption by the Na 2 molecule to highly excited gerade states followed by (a) direct ionization by absorbing a third photon or (b) coupling to the molecular Na 2 D 1 PIμ Rydberg state which is subsequently ionized by absorbing a third photon. This mechanism, i.e., a two-photon resonance three photon ionization process, explains a recent experimental observation of Roussel et al. It is suggested that the very same mechanism is also responsible for a similar observation reported by Polak-Dingels et al in their work using two crossed Na beams. In the latter two studies the laser-induced associative ionization processes were reported to be responsible for producing the Na 2 + ion. From the ratio of molecular to atomic concentration in the crossed beam experiment of Polak-Dingels et al we estimate that the cross section for producing Na 2 + through laser-induced associative ionization is at least four orders of magnitude smaller than ionization through the two-photon resonance three photon ionization process in Na 2 molecules

    Sodium-potassium alloy is used in specific application in French Fast Breeder Reactors as: cold traps, NaK bubbler for argon purification, valves and also in experimental irradiation devices. lt has been preferred to sodium because it is liquid from + 7 deg. C for the most common peritectic alloy. After its use, NaK is considered as a hazardous waste (nuclear or not) due to its high reactivity with air and water. The most important risk remains in handling NaK systems which have not been operated for some time. The NaK will be covered with a crust of the superoxide K02 which is a strong oxidising agent. Thermodynamically, K02 will react with most organic material or metallic dust or swarfs and can also react with additional NaK to give sufficient heat to boil part of the NaK, resulting in a sudden increase in pressure and small explosions. We describe the formation given to experimenters in our Sodium School and the CEA's experience in treating specific devices for transportation, decanting of tanks, tank opening and NaK removal.

    The Na/K pump exports cytoplasmic Na ions while importing K ions, and its activity is thought to be affected by restricted intracellular Na diffusion in cardiac myocytes. Lu and Hilgemann find instead that the pump can enter an inactivated state and that inactivation can be relieved by cytoplasmic Na.

  11. Myocardial Na,K-ATPase: Clinical aspects

    2003-01-01

    The specific binding of digitalis glycosides to Na,K-ATPase is used as a tool for Na,K-ATPase quantification with high accuracy and precision. In myocardial biopsies from patients with heart failure, total Na,K-ATPase concentration is decreased by around 40%; a correlation exists between a decrease in heart function and a decrease in Na,K-ATPase concentration. During digitalization, around 30% of remaining pumps are occupied by digoxin. Myocardial Na,K-ATPase is also influenced by other drugs used for the treatment of heart failure. Thus, potassium loss during diuretic therapy has been found to reduce myocardial Na,K-ATPase, whereas angiotensin-converting enzyme inhibitors may stimulate Na,K pump activity. Furthermore, hyperaldosteronism induced by heart failure has been found to decrease Na,K-ATPase activity. Accordingly, treatment with the aldosterone antagonist, spironolactone, may also influence Na,K-ATPase activity. The importance of Na,K pump modulation with heart disease, inhibition in digitalization and other effects of medication should be considered in the context of sodium, potassium and calcium regulation. It is recommended that digoxin be administered to heart failure patients who, after institution of mortality-reducing therapy, still have heart failure symptoms, and that the therapy be continued if symptoms are revealed or reduced. Digitalis glycosides are the only safe inotropic drugs for oral use that improve hemodynamics in heart failure. An important aspect of myocardial Na,K pump affection in heart disease is its influence on extracellular potassium (Ke) homeostasis. Two important aspects should be considered: potassium handling among myocytes, and effects of potassium entering the extracellular space of the heart via the bloodstream. It should be noted that both of these aspects of Ke homeostasis are affected by regulatory aspects, eg, regulation of the Na,K pump by physiological and pathophysiological conditions, as well as by medical

    Science and technology are directly related to the development of a country. The research and development projects in CNEN are financed by the direct resources of the budget of the Union and of the Development Agencies such as FINEP and CNPq. In general, project managers believe they can succeed when they complete a project on schedule, budget, and anticipated requirements, which is commonly known as a 'triple constraint' or 'iron triangle'. However, in the review of the literature, other criteria for evaluating success in projects, such as the benefits generated by society, the development of the team's capabilities, future opportunities, new technologies, among others, were verified. In this way, in order to assist the manager in the evaluation of this type of project, the present research carried out a review in the literature aiming to find concepts about success in projects and their evaluation criteria, proposed a model based on the theoretical reference and Importance and use of these criteria with the CNEN specialists, who work directly in the R and D projects of a public ICT in the nuclear area. The results showed that the criteria proposed in the model have a high degree of importance and show a decrease in the degree of utilization, suggesting that the criteria used in the model can help managers in the evaluation of these projects.

    Cabbage-like NaInS 2 microstructures have been synthesized by reacting In(NO 3 ) 3 with the alkaline sulfur aqueous solution of NaOH in a simple hydrothermal process without any shape-directing surfactants. The cabbage-like NaInS 2 architectures are monodispersed in large quantities. The cabbage-like morphologies depend strongly on the different ratios of S powder to NaOH, the reaction temperature and reaction time. The possible growth mechanism for the formation of cabbage-like NaInS 2 architectures is discussed. The cabbage-like NaInS 2 architectures exhibit the superiority of photocatalytic performance for the photodegradation of RhB irradiation under visible light irradiation. It is believed that the photocatalytic superiority of the cabbage-like NaInS 2 architectures is mainly due to their special surface areas and inner interconnected structural features. - Graphical abstract: Cabbage-like NaInS 2 microstructures were facilely synthesized via simple hydrothermal reaction.

    A general approach of the state of art of the harmonic generation, its sources, its limits, its measurement methods and its effects on the electric system components is presented. This thesis shows that this is an open field to research, modelling and solutions. It also helps towards the investigation of the effects caused by harmonics on the conventional KWh energy meters and on potential and current transformers. It presents the basis for the development and construction of prototypes to be utilized in the generation and measurement of harmonics. Finally a practical approach has been given to calculate the equivalent harmonic impedance as seen by a giving consumer. (author)

  17. Glutathionylation-Dependence of Na+-K+-Pump Currents Can Mimic Reduced Subsarcolemmal Na+ Diffusion

    The existence of a subsarcolemmal space with restricted diffusion for Na+ in cardiac myocytes has been inferred from a transient peak electrogenic Na+-K+ pump current beyond steady state on reexposure of myocytes to K+ after a period of exposure to K+-free extracellular solution. The transient peak current is attributed to enhanced electrogenic pumping of Na+ that accumulated in the diffusion-restricted space during pump inhibition in K+-free extracellular solution. However, there are no known physical barriers that account for such restricted Na+ diffusion, and we examined if changes of activity of the Na+-K+ pump itself cause the transient peak current. Reexposure to K+ reproduced a transient current beyond steady state in voltage-clamped ventricular myocytes as reported by others. Persistence of it when the Na+ concentration in patch pipette solutions perfusing the intracellular compartment was high and elimination of it with K+-free pipette solution could not be reconciled with restricted subsarcolemmal Na+ diffusion. The pattern of the transient current early after pump activation was dependent on transmembrane Na+- and K+ concentration gradients suggesting the currents were related to the conformational poise imposed on the pump. We examined if the currents might be accounted for by changes in glutathionylation of the β1 Na+-K+ pump subunit, a reversible oxidative modification that inhibits the pump. Susceptibility of the β1 subunit to glutathionylation depends on the conformational poise of the Na+-K+ pump, and glutathionylation with the pump stabilized in conformations equivalent to those expected to be imposed on voltage-clamped myocytes supported this hypothesis. So did elimination of the transient K+-induced peak Na+-K+ pump current when we included glutaredoxin 1 in patch pipette solutions to reverse glutathionylation. We conclude that transient K+-induced peak Na+-K+ pump current reflects the effect of conformation-dependent β1 pump subunit

    Full Text Available Com o objetivo de avaliar a junção tiroidiana após uso crônico da amiodarona, em área de deficiência de iodo e endemia chagásica, 24 pacientes foram analisados antes e após três e nove meses de uso da droga. A avaliação constou de exame clínico, dosagem sérica de T4, T3, rT3, TSH, anticorpo antitiroglobulina e TSH 30 minutos após infusão venosa de uma ampola de 200µg de TRH. A captação do iodo radioativo 131 e a cintilografia datiróide foram realizadas antes e aos 9 meses após tratamento. Disfunção tiroidiana ocorreu em 20,8% dos pacientes sendo 12,5% de hipertiroidismo e 8,3% de hipotiroidismo, com anticorpos antitiroglobulina negativos. Captação do iodo radioativo 131 foi positiva em um paciente hipertiroideo com bócio. O diagnóstico de hipertiroidismo foi melhor evidenciado pela resposta reduzida ou bloqueada do TSH ao TRH e não pela concentração do T3 no soro e o de hipotiroidismo pela concentração elevada do TSH. O TSH elevado desde o início do tratamento pode predispor ao aparecimento de bócio. Concluímos que o uso da amiodarona em nossa região deve serjudiciosamente analisado, sendo a função tiroidiana cuidadosamente monitorizada antes e durante o tratamento.In order to evaluate the development of thyroid dysfunction during chronic amiodarone treatment in an area deficient in iodine and endemic for Chagas 'disease, a group of 24patients wasprospectively studied.

    The Na/K pump actively exports 3 Na(+) in exchange for 2 K(+) across the plasmalemma of animal cells. As in other P-type ATPases, pump function is more effective when the relative affinity for transported ions is altered as the ion binding sites alternate between opposite sides of the membrane. Deletion of the five C-terminal residues from the alpha-subunit diminishes internal Na(+) (Na(i)(+)) affinity approximately 25-fold [Morth et al. (2007) Nature 450:1043-1049]. Because external Na(+) (Na(o)(+)) binding is voltage-dependent, we studied the reactions involving this process by using two-electrode and inside-out patch voltage clamp in normal and truncated (DeltaKESYY) Xenopus-alpha1 pumps expressed in oocytes. We observed that DeltaKESYY (i) decreased both Na(o)(+) and Na(i)(+) apparent affinities in the absence of K(o)(+), and (ii) did not affect apparent Na(o)(+) affinity at high K(o)(+). These results support a model of strict sequential external release of Na(+) ions, where the Na(+)-exclusive site releases Na(+) before the sites shared with K(+) and the DeltaKESYY deletion only reduces Na(o)(+) affinity at the shared sites. Moreover, at nonsaturating K(o)(+), DeltaKESYY induced an inward flow of Na(+) through Na/K pumps at negative potentials. Guanidinium(+) can also permeate truncated pumps, whereas N-methyl-D-glucamine cannot. Because guanidinium(o)(+) can also traverse normal Na/K pumps in the absence of both Na(o)(+) and K(o)(+) and can also inhibit Na/K pump currents in a Na(+)-like voltage-dependent manner, we conclude that the normal pathway transited by the first externally released Na(+) is large enough to accommodate guanidinium(+).

    Understanding brain organization of speech production has been a principal goal of neuroscience. Historically, brain speech production has been associated with so-called Broca’s area (Brodmann area –BA- 44 and 45), however, modern neuroimaging developments suggest speech production is associated with networks rather than with areas. The purpose of this paper was to analyze the connectivity of BA47 ( pars orbitalis) in relation to language . A meta-analysis was conducted to assess the language network in which BA47 is involved. The Brainmap database was used. Twenty papers corresponding to 29 experimental conditions with a total of 373 subjects were included. Our results suggest that BA47 participates in a “frontal language production system” (or extended Broca’s system). The BA47  connectivity found is also concordant with a minor role in language semantics. BA47 plays a central role in the language production system.

    1984-01-01

    We assessed 22Na+ uptake by erythrocytes (RBC) from 38 individuals with essential hypertension and 37 healthy controls. All subjects were male, white, non-obese and with normal renal function, obviating sex, race, hormonal, ponderal and renal factors known to influence RBC Na+ handling. The mean +/- sem 22Na+ uptake of the patients was 284 +/- 16 mumole/liter RBC/hour while that of normal controls was 249 +/- 11 mumole/liter RBC/hour; although the difference reached borderline significance, individual values showed considerable overlap. Consequently, in our population, RBC 22Na+ uptake is not a reliable marker for essential hypertension. We believe that previous studies should be reassessed with regard to patients' characteristics and future studies employ rigorous criteria in selection of subjects

    The universe of painful Na-channelopathies--human disorders caused by mutations in voltage-gated sodium channels--has recently expanded in three dimensions. We now know that mutations of sodium channels cause not only rare genetic 'model disorders' such as inherited erythromelalgia and channelopathy-associated insensitivity to pain but also common painful neuropathies. We have learned that mutations of NaV1.8, as well as mutations of NaV1.7, can cause painful Na-channelopathies. Moreover, recent studies combining atomic level structural models and pharmacogenomics suggest that the goal of genomically guided pain therapy may not be unrealistic. Copyright © 2013 Elsevier Ltd.

    The carbaryl adsorption-desorption isotherms of zeolite NaY and hexadecyl trimethyl ammonium bromide (HTAB) modified zeolite NaY were investigated. Zeolite NaY was synthesized and modified by HTAB in the concentration range 0.1 - 10.0 mM. The adsorption isotherms indicated that zeolite modified with HTAB could significantly enhance the carbaryl adsorption capacity. Zeolite NaY modified with 5.0 mM HTAB gave great carbaryl adsorption because of hydrophilic surface. The 5.0 mM HTAB could adsorb up to 145.75 ppm g-1 of carbaryl which was equivalent to a 36.7% increase. The Surface area characterization showed the remaining of pore volume and pore size diameter and external surface area whereas the BET surface area and micropore surface area of modified zeolite slightly decreased. The XRD results indicate that modification of zeolite NaY with HTAB does not change the crystallinity of the starting zeolite. The elemental analysis indicated that the Si/Al ratio of synthesized zeolite NaY was close to 2.43. Desorption of carbaryl was tested by organic solvents such as methanol, ethanol, tetrahydrofuran, hexane and Deionized water. The results demonstrated that the percentage desorption of methanol is the highest. Carbaryl was quantitatively desorbed with percentage desorption of 82-100 %. It indicated sorption mechanism of carbaryl on the modified sorbent which was principally driven by hydrophobic forces.

    Full Text Available This study was a longitudinal assessment of mercury exposure in schoolchildren in an urban area of the Brazilian Amazon. The study population consisted of 90 children whose exposure levels were assessed by testing mercury levels in the umbilical cord blood and mothers' blood samples in 2000-2001, and in the children's hair and blood samples. The study also used a questionnaire on demographic and socioeconomic data, fish consumption, and self-reported disease history. Mean mercury level in hair in 2010 was approximately 1µg/g, ranging up to 8.22µg/g, similar to 2004 and 2006. These figures can be explained by low fish consumption. Mean blood mercury levels at birth exceeded 10µg/L, ranging up to nearly 60µg/L, which indicates mercury transfer across the placenta. There was a significant increase in blood mercury from 2004 to 2006 (p O objetivo deste estudo foi realizar avaliação longitudinal da exposição de crianças de uma área urbana da Amazônia brasileira ao mercúrio (Hg.

    The streptozotocin-induced diabetic rat was used to test the hypothesis that Na + -H + exchange activity in the proximal tubule luminal membrane would be increased in association with renal hypertrophy, altered glomerular hemodynamics, enhanced filtered load and tubular reabsorption of 22 Na + , and stimulated 22 Na= pump activity in the basolateral membrane, previously reported characteristics of this experimental animal model. Amiloride-sensitive H + gradient-dependent Na + uptake and Na + gradient-dependent H + flux were increased in brush-border membrane vesicles from the streptozotocin-treated animals. Na + gradient-dependent uptakes of phosphate, D-glucose, L-proline, and myoinositol were decreased in the drug-induced diabetic animals. These membrane transport alterations were not found when the streptozotocin-diabetic animals were treated with insulin

    The existence of a subsarcolemmal space with restricted diffusion for Na+ in cardiac myocytes has been inferred from a transient peak electrogenic Na+-K+ pump current beyond steady state on reexposure of myocytes to K+ after a period of exposure to K+-free extracellular solution. The transient peak current is attributed to enhanced electrogenic pumping of Na+ that accumulated in the diffusion-restricted space during pump inhibition in K+-free extracellular solution. However, there are no know...

    Although the hygroscopicity of a NaNO(3)/water microdroplet and a polyalcohol/water microdroplet, two of the most important aerosols in atmosphere, has been widely studied, little is known about the relationship between the hygroscopic behavior of mixed NaNO(3)/polyalcohol/water droplets and their structures on the molecular level. In this study, the hygroscopicity of mixed glycerol/NaNO(3)/water droplets deposited on a hydrophobic substrate was studied by micro-Raman spectroscopy with organic-to-inorganic molar ratios (OIRs) of 0.5, 1, and 2. In the mixed glycerol/NaNO(3)/water droplets, glycerol molecules tended to combine with Na(+) and NO(3)(-) ions by electrostatic interaction and hydrogen bonding, respectively. On the basis of the analyses of the changes of symmetric stretching (v(s)-CH(2)), asymmetric stretching (v(a)-CH(2)), their area ratio (Av(a)-CH(2)/Av(s)-CH(2)) of glycerol, and symmetric stretching band of NO(3)(-) (ν(1)-NO(3)(-)) with relative humidity (RH), it was found that the conformation of glycerol was transformed from αα mainly to γγ and partly to αγ with a decreasing RH in the mixed droplets, contrary to the case in the glycerol/water droplet. In addition, the glycerol with γγ and αγ conformation had strong interaction with Na(+) and NO(3)(-) respectively, which suppressed the formation of contact of ions and delayed the efflorescence relative humidity (ERH) for the mixed droplets compared to the NaNO(3)/water droplet. © 2012 American Chemical Society

    Controlling the formation of interstitial Na (Nai) self-compensating defects has been a long-term physics problem for effective Na doping in ZnO. Herein, we present an experimental approach to the suppression of Nai defects in ZnO via Na and F codoping under an oxygen-rich condition during the molecular beam epitaxy growth process. It is found that the incorporation of such large numbers of Na and F dopants (˜1020 cm-3) does not cause an obvious influence on the lattice parameters. Hall-effect measurements demonstrate that F doping efficiently raises the Fermi level (EF) of ZnO films, which is expected to make the formation energy of Nai and NaZn increase and decrease, respectively. Most of the Na atoms occupy the substitutional Zn sites, and the formation of Nai is suppressed consequently. Secondary ion mass spectrometry measurements reveal that F and Na atoms are tightly bonded together due to their strong Coulomb interaction. The enhanced deep level emission (DLE) in ZnO:Na-F is ascribed to the considerable amount of isolated Zn vacancy (VZn) defects induced by the elevated EF and the formation of neutral (" separators="| FO + - Na Zn - ) 0 complexes. On the other hand, formation of (" separators="| FO + - VZn 2 - ) - complexes in ZnO:F exhausts most of the isolated Zn vacancies, leading to the disappearance of the DLE band.

    We examined whether abnormal skeletal muscle Na(+),K(+)-pumps underlie impaired exercise performance in haemodialysis patients (HDP) and whether these are improved in renal transplant recipients (RTx). Peak oxygen consumption ( O(2peak)) and plasma [K(+)] were measured during incremental exercise in 9RTx, 10 HDP and 10 healthy controls (CON). Quadriceps peak torque (PT), fatigability (decline in strength during thirty contractions), thigh muscle cross-sectional area (TMCSA) and vastus lateralis Na(+),K(+)-pump maximal activity, content and isoform (α(1)-α(3), β(1)-β(3)) abundance were measured. O(2peak) was 32 and 35% lower in RTx and HDP than CON, respectively (P Na(+),K(+)-pump activity was 28 and 31% lower in RTx and HDP, respectively than CON (P Na(+),K(+)-pump activity (r = 0.45, P = 0.02). O(2peak) and muscle Na(+),K(+)-pump activity were depressed and muscle fatigability increased in HDP, with no difference observed in RTx. These findings are consistent with the possibility that impaired exercise performance in HDP and RTx may be partially due to depressed muscle Na(+),K(+)-pump activity and relative TMCSA.

  1. Prolonged Intracellular Na+ Dynamics Govern Electrical Activity in Accessory Olfactory Bulb Mitral Cells.

    Full Text Available Persistent activity has been reported in many brain areas and is hypothesized to mediate working memory and emotional brain states and to rely upon network or biophysical feedback. Here, we demonstrate a novel mechanism by which persistent neuronal activity can be generated without feedback, relying instead on the slow removal of Na+ from neurons following bursts of activity. We show that mitral cells in the accessory olfactory bulb (AOB, which plays a major role in mammalian social behavior, may respond to a brief sensory stimulation with persistent firing. By combining electrical recordings, Ca2+ and Na+ imaging, and realistic computational modeling, we explored the mechanisms underlying the persistent activity in AOB mitral cells. We found that the exceptionally slow inward current that underlies this activity is governed by prolonged dynamics of intracellular Na+ ([Na+]i, which affects neuronal electrical activity via several pathways. Specifically, elevated dendritic [Na+]i reverses the Na+-Ca2+ exchanger activity, thus modifying the [Ca2+]i set-point. This process, which relies on ubiquitous membrane mechanisms, is likely to play a role in other neuronal types in various brain regions.

    Full Text Available OBJECTIVES: To estimate prevalence, age-of-onset, gender distribution and identify correlates of lifetime psychiatric disorders in the São Paulo Metropolitan Area (SPMA. METHODS: The São Paulo Megacity Mental Health Survey assessed psychiatric disorders on a probabilistic sample of 5,037 adult residents in the SPMA, using the World Mental Health Survey Version of the Composite International Diagnostic Interview. Response rate was 81.3%. RESULTS: Lifetime prevalence for any disorder was 44.8%; estimated risk at age 75 was 57.7%; comorbidity was frequent. Major depression, specific phobias and alcohol abuse were the most prevalent across disorders; anxiety disorders were the most frequent class. Early age-of-onset for phobic and impulse-control disorders and later age-of-onset for mood disorders were observed. Women were more likely to have anxiety and mood disorders, whereas men, substance use disorders. Apart from conduct disorders, more frequent in men, there were no gender differences in impulse-control disorders. There was a consistent trend of higher prevalence in the youngest cohorts. Low education level was associated to substance use disorders. CONCLUSIONS: Psychiatric disorders are highly prevalent among the general adult population in the SPMA, with frequent comorbidity, early age-of-onset for most disorders, and younger cohorts presenting higher rates of morbidity. Such scenario calls for vigorous public health action.OBJETIVOS: Estimar a prevalência, idade de início, distribuição por sexo e idade e identifica fatores correlacionados à morbidade psiquiátrica na Região Metropolitana de São Paulo (RMSP.

  3. Elastic Coulomb breakup of 34Na

    2016-08-01

    Background: 34Na is conjectured to play an important role in the production of seed nuclei in the alternate r -process paths involving light neutron rich nuclei very near the β -stability line, and as such, it is important to know its ground state properties and structure to calculate rates of the reactions it might be involved in, in the stellar plasma. Found in the region of `island of inversion', its ground state might not be in agreement with normal shell model predictions. Purpose: The aim of this paper is to study the elastic Coulomb breakup of 34Na on 208Pb to give us a core of 33Na with a neutron and in the process we try and investigate the one neutron separation energy and the ground state configuration of 34Na. Method: A fully quantum mechanical Coulomb breakup theory within the architecture of post-form finite range distorted wave Born approximation extended to include the effects of deformation is used to research the elastic Coulomb breakup of 34Na on 208Pb at 100 MeV/u. The triple differential cross section calculated for the breakup is integrated over the desired components to find the total cross-section, momentum, and angular distributions as well as the average momenta, along with the energy-angular distributions. Results: The total one neutron removal cross section is calculated to test the possible ground state configurations of 34Na. The average momentum results along with energy-angular calculations indicate 34Na to have a halo structure. The parallel momentum distributions with narrow full widths at half-maxima signify the same. Conclusion: We have attempted to analyze the possible ground state configurations of 34Na and in congruity with the patterns in the `island of inversion' conclude that even without deformation, 34Na should be a neutron halo with a predominant contribution to its ground state most probably coming from 33Na(3 /2+)⊗ 2 p3 /2ν configuration. We also surmise that it would certainly be useful and rewarding to test our

    Context. ALMA is providing us essential information on where certain molecules form. Observing where these molecules emission arises from, the physical conditions of the gas, and how this relates with the presence of other species allows us to understand the formation of many species, and to significantly improve our knowledge of the chemistry that occurs in the space. Aims: We studied the molecular distribution of NaCN around IRC +10216, a molecule detected previously, but whose origin is not clear. High angular resolution maps allow us to model the abundance distribution of this molecule and check suggested formation paths. Methods: We modeled the emission of NaCN assuming local thermal equilibrium (LTE) conditions. These profiles were fitted to azimuthal averaged intensity profiles to obtain an abundance distribution of NaCN. Results: We found that the presence of NaCN seems compatible with the presence of CN, probably as a result of the photodissociation of HCN, in the inner layers of the ejecta of IRC +10216. However, similar as for CH3CN, current photochemical models fail to reproduce this CN reservoir. We also found that the abundance peak of NaCN appears at a radius of 3 × 1015 cm, approximately where the abundance of NaCl, suggested to be the parent species, starts to decay. However, the abundance ratio shows that the NaCl abundance is lower than that obtained for NaCN. We expect that the LTE assumption might result in NaCN abundances higher than the real ones. Updated photochemical models, collisional rates, and reaction rates are essential to determine the possible paths of the NaCN formation.

    Recent studies in hepatocytes indicate that Na(+)-coupled HCO3- transport contributes importantly to regulation of intracellular pH and membrane HCO3- transport. However, the direction of net coupled Na+ and HCO3- movement and the effect of HCO3- on Na+ turnover and Na+/K+ pump activity are not known. In these studies, the effect of HCO3- on Na+ influx and turnover were measured in primary rat hepatocyte cultures with 22Na+, and [Na+]i was measured in single hepatocytes using the Na(+)-sensitive fluorochrome SBFI. Na+/K+ pump activity was measured in intact perfused rat liver and hepatocyte monolayers as Na(+)-dependent or ouabain-suppressible 86Rb uptake, and was measured in single hepatocytes as the effect of transient pump inhibition by removal of extracellular K+ on membrane potential difference (PD) and [Na+]i. In hepatocyte monolayers, HCO3- increased 22Na+ entry and turnover rates by 50-65%, without measurably altering 22Na+ pool size or cell volume, and HCO3- also increased Na+/K+ pump activity by 70%. In single cells, exposure to HCO3- produced an abrupt and sustained rise in [Na+]i from approximately 8 to 12 mM. Na+/K+ pump activity assessed in single cells by PD excursions during transient K+ removal increased congruent to 2.5-fold in the presence of HCO3-, and the rise in [Na+]i produced by inhibition of the Na+/K+ pump was similarly increased congruent to 2.5-fold in the presence of HCO3-. In intact perfused rat liver, HCO3- increased both Na+/K+ pump activity and O2 consumption. These findings indicate that, in hepatocytes, net coupled Na+ and HCO3- movement is inward and represents a major determinant of Na+ influx and Na+/K+ pump activity. About half of hepatic Na+/K+ pump activity appears dedicated to recycling Na+ entering in conjunction with HCO3- to maintain [Na+]i within the physiologic range

    The present summary describes the carried out work of the application of the techniques of gamma profiling in a distillation tower, for the oil industry in Mexico. The study consisted on the application of the gamma profiling technique. An arrangement detector source aligned in a horizontal way was collocated to make a vertical scanning along the tower, in such a way that the signal obtained by this technique allows see the interior of the same one, with the objective of being able to diagnose its operation conditions. According to the applied technique, the height of the signal obtained in the graphs depends on the attenuation of the source radiation, in such a way that if crosses areas of more or small density, the width of the signal decreases or is increased and starting from these results a diagnostic was interpreted. For the profiling service of the distillation tower, Na-24 source and radiation detection equipment coupled to a system of data acquisition was used. Relative to radiological protection a controlled area was defined where the radioactive source was used to avoid unnecessary exhibitions to the plant personnel. Relative to the technique use, in this case stands out the use of Na-24 like source since they required this way the conditions of thickness and diameter of the tower. At the end of the study satisfactory results were obtained. (Author)

    Thin film NaI(Tl) scintillators, of areas of up to 130 cm 2 , have been fabricated and characterized for use on soft x-ray imaging photomultiplier tubes. Relevant parameters of photon-counting imaging detectors are defined and used to predict the performance of several materials, including CsI(Na), CsI(Tl), CaF 2 (Eu), Lu 2 (SiO 4 )O:Ce, and NaI(Tl), as thin film scintillators on fiber optic substrates. Also, x-ray imaging methodologies are compared. The NaI(Tl) films were vapor-deposited onto quartz and fiber optic substrates using a powder flash deposition technique. When compared to single crystal NaI(Tl), the films were found to have equally high light yield but lower energy resolution. Light yield optimization was studied in detail including the effects of substrate temperature, activator concentration in the evaporant, and boat temperature. Spatial resolution as well as parallax errors are discussed and measured for film thicknesses up to 61 μm. A technique is described that can substantially increase the light collection of high index films on fiber optic disks. The light collection was improved by 20% by coating the disk with potassium silicate before the NaI(Tl) deposition. Large area films, up to 130 cm 2 , had a spatial uniformity of response within ±1.5% for count rate and ±3.5% for light yield, and their spatial resolution exceeded 16.6 lp mm -1 when deposited onto fiber optic substrates. The 8-keV x-ray detection efficiency of the microchannel plate imaging photomultiplier tube coupled to a NaI(Tl) film scintillator is predicted to be 88%. Other uses for the films are also described

    The low-energy structures of the radioactive nuclei 20, 21Na have been examined using Coulomb excitation at the TRIUMF-ISAC radioactive ion beam facility. Beams of ˜ 5×106 ions/s were accelerated to 1.7MeV/A and Coulomb excited in a 0.5mg/cm^2 natTi target. Two TIGRESS HPGe clover detectors perpendicular to the beam axis were used for γ -ray detection, while scattered nuclei were observed by the Si detector BAMBINO. For 21Na , Coulomb excitation from the 3/2+ ground state to the first excited 5/2+ state was observed, while for 20Na , Coulomb excitation was observed from the 2+ ground state to the first excited 3+ and 4+ states. For both beams, B ( λ L) values were determined using the 2+ rightarrow 0+ de-excitation in 48Ti as a reference. The resulting B( E2) ↓ value for 21Na is 137±9 e^2fm^4, while the resulting B( λ L) ↓ values for 20Na are 55±6 e^2fm^4 for the 3+ rightarrow 2+ , 35.7±5.7 e^2 fm^4 for the 4+ rightarrow 2+ , and 0.154±0.030 μ_ N^2 for the 4+ rightarrow 3+ transitions. This analysis significantly improves the measurement of the 21Na B( E2) value, and provides the first experimental determination of B( λ L) values for the proton dripline nucleus 20Na .-1

    Salt stress imposes severe limitations on plant growth, however, the extent of growth reduction depends upon the soil salinity level and the plant species. One of the mechanisms employed by salt tolerant plants is the effective vacuolar compartmentalization of sodium. The sequestration of sodium into the vacuole occurs by the operation of a Na+/H+ antiport located at the tonoplast. Evidence for a plant vacuolar Na+/H+ antiport has been demonstrated in tissues, intact vacuoles and isolated tonoplast vesicles. In sugar beet cell suspensions, the activity of the vacuolar Na+/H+ antiport increased with increasing NaCl concentrations in the growth medium. This increased activity was correlated with the increased synthesis of a 170 kDa tonoplast polypeptide. In vivo labelling of tonoplast proteins showed the enhanced synthesis of the 170 kDa polypeptide not only upon exposure of the cells to salt, but also when the cells were grown in the presence of amiloride. Exposure of the cells to amiloride also resulted in increased vacuolar Na+/H+ antiport activity. Polyclonal antibodies raised against the 170 kDa polypeptide almost completely inhibited the antiport activity, suggesting the association of this protein with the plant vacuolar Na+/H+ antiport. Antibodies against the Na+/H+ antiport-associated polypeptide were used to screen a Beta lambda ZAP expression library. A partial clone of 1.65 kb was sequenced and found to encode a polypeptide with a putative transmembrane domain and a large hydrophilic C terminus. This clone showed no homology to any previously cloned gene at either the nucleic acid or the amino acid level.

    A cupric oxide (CuO) nanocrystal-doped NaCl single crystal and a pure NaCl single crystal are grown by using the Czochralski (Cz) method. A number of techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) analysis, Fourier transform infrared (FT-IR) spectroscopy, Raman spectroscopy, optical absorption in the UV—visible range, and photoluminescence (PL) spectroscopy are used to characterize the obtained NaCl and NaCl:CuO crystals. It is observed that the average radius of CuO crystallites in NaCl:CuO crystal is about 29.87 nm, as derived from the XRD data analysis. Moreover, FT-IR and Raman spectroscopy results confirm the existence of the monoclinic CuO phase in NaCl crystal. UV—visible absorption measurements indicate that the band gap of the NaCl:CuO crystal is 434 nm (2.85 eV), and it shows a significant amount of blue-shift (ΔE g = 1 eV) in the band gap energy of CuO, which is due to the quantum confinement effect exerted by the CuO nanocrystals. The PL spectrum of the NaCl:CuO shows a broad emission band centred at around 438 nm, which is consistent with the absorption measurement.

    Ouabain, a specific inhibitor of the Na+/K+-pump, has previously been shown to interfere with intercellular communication. We have recently demonstrated a mechanism of this action of ouabain (1). We have showed that gap junctions between vascular smooth muscle cells (SMCs) are regulated through...... an interaction between the Na+/K+-pump and the Na+/Ca2+-exchanger leading to an increase in the intracellular calcium concentration in discrete areas near the plasma membrane. This regulation suggests a close association of the proteins in microdomains. We have also suggested that this Na...

    Full Text Available Necator americanus Glutathione-S-Transferase-1 (Na-GST-1 plays a role in the digestion of host hemoglobin by adult N. americanus hookworms. Vaccination of laboratory animals with recombinant Na-GST-1 is associated with significant protection from challenge infection. Recombinant Na-GST-1 was expressed in Pichia pastoris and adsorbed to aluminum hydroxide adjuvant (Alhydrogel according to current Good Manufacturing Practice. Two Phase 1 trials were conducted in 142 healthy adult volunteers in the United States and Brazil, first in hookworm-naïve individuals and then in residents of a N. americanus endemic area in Brazil. Volunteers received one of three doses of recombinant Na-GST-1 (10, 30, or 100 μg adjuvanted with Alhydrogel, adjuvanted with Alhydrogel and co-administered with an aqueous formulation of Glucopyranosyl Lipid A (GLA-AF, or the hepatitis B vaccine. Vaccinations were administered via intramuscular injection on days 0, 56, and 112. Na-GST-1/Alhydrogel was well tolerated in both hookworm-naïve and hookworm-exposed adults, with the most common adverse events being mild to moderate injection site pain and tenderness, and mild headache and nausea; no vaccine-related severe or serious adverse events were observed. Antigen-specific IgG antibodies were induced in a dose-dependent fashion, with increasing levels observed after each vaccination in both trials. The addition of GLA-AF to Na-GST-1/Alhydrogel did not result in significant increases in specific IgG responses. In both the US and Brazil studies, the predominant IgG subclass induced against Na-GST-1 was IgG1, with lesser amounts of IgG3. Vaccination of both hookworm-naïve and hookworm-exposed adults with recombinant Na-GST-1 was safe, well tolerated, and resulted in significant antigen-specific IgG responses. Based on these results, this vaccine will be advanced into clinical trials in children and eventual efficacy studies.ClinicalTrials.gov (NCT01261130 for the Brazil trial

  1. NaI(Tl) electron energy resolution

    CERN Document Server

    Mengesha, W

    2002-01-01

    NaI(Tl) electron energy resolution eta sub e was measured using the Modified Compton Coincidence Technique (MCCT). The MCCT allowed detection of nearly monoenergetic internal electrons resulting from the scattering of incident 662 keV gamma rays within a primary NaI(Tl) detector. Scattered gamma rays were detected using a secondary HPGe detector in a coincidence mode. Measurements were carried out for electron energies ranging from 16 to 438 keV, by varying the scattering angle. Measured HPGe coincidence spectra were deconvolved to determine the scattered energy spectra from the NaI(Tl) detector. Subsequently, the NaI(Tl) electron energy spectra were determined by subtracting the energy of scattered spectra from the incident source energy (662 keV). Using chi-squared minimization, iterative deconvolution of the internal electron energy spectra from the measured NaI(Tl) spectra was then used to determine eta sub e at the electron energy of interest. eta sub e values determined using this technique represent va...

    Full Text Available The São Paulo Megacity Mental Health Survey is a population-based cross-sectional survey of psychiatric morbidity, assessing a probabilistic sample of household residents in the São Paulo Metropolitan Area, aged 18 years and over. Respondents were selected from a stratified multistage clustered area probability sample of households, covering all 39 municipalities, without replacement. Respondents were assessed using the World Mental Health Survey version of the World Health Organization Composite International Diagnostic Interview (WMH-CIDI, which was translated and adapted into the Brazilian-Portuguese language. Data was collected between May 2005 and April 2007 by trained lay interviewers. The World Mental Health Survey version of the Composite International Diagnostic Interview comprises clinical and non-clinical sections, arranged as Part I and Part II, producing diagnoses according to the Diagnostic and Statistical Manual of Mental Disorders - Fourth Edition, and the International Classification of Diseases - 10th Revision. Mood, anxiety, impulse-control and substance use disorders, and suicide-related behavior, considered core disorders, as well as socio-demographic information, were assessed in all respondents. Non-clinical modules and non-core clinical sections (obsessive-compulsive disorder, post-traumatic stress disorder, gambling, eating disorders, neurasthenia, pre-menstrual disorders, psychotic symptoms and personality traits were assessed in a sub-sample (2,942 respondents, composed by all respondents with at least one core disorder and a 25% random sample of those who were non-cases. A total of 5,037 individuals were interviewed, with a global response rate of 81.3%.

    NaI(Tl) detectors, having a good detection efficiency, are used to detect gamma rays in field surveys. But the poor energy resolution hinders their applications, despite the use of traditional methods to resolve the overlapped gamma-ray peaks. In this paper, the maximum likelihood (ML) solution is used to resolve the spectrum. The ML method,which is capable of decomposing the peaks in energy difference of over 2/3 FWHM, is applied to scale NaI(Tl) the spectrometer. The result shows that the net area is in proportion to the content of isotopes and the precision of scaling is better than the stripping ration method. (authors)

  9. Anion-coupled Na efflux mediated by the human red blood cell Na/K pump

    International Nuclear Information System (INIS)

    Dissing, S.; Hoffman, J.F.

    1990-01-01

    The red cell Na/K pump is known to continue to extrude Na when both Na and K are removed from the external medium. Because this ouabain-sensitive flux occurs in the absence of an exchangeable cation, it is referred to as uncoupled Na efflux. This flux is also known to be inhibited by 5 mM Nao but to a lesser extent than that inhibitable by ouabain. Uncoupled Na efflux via the Na/K pump therefore can be divided into a Nao-sensitive and Nao-insensitive component. We used DIDS-treated, SO4-equilibrated human red blood cells suspended in HEPES-buffered (pHo 7.4) MgSO4 or (Tris)2SO4, in which we measured 22Na efflux, 35SO4 efflux, and changes in the membrane potential with the fluorescent dye, diS-C3 (5). A principal finding is that uncoupled Na efflux occurs electroneurally, in contrast to the pump's normal electrogenic operation when exchanging Nai for Ko. This electroneutral uncoupled efflux of Na was found to be balanced by an efflux of cellular anions. (We were unable to detect any ouabain-sensitive uptake of protons, measured in an unbuffered medium at pH 7.4 with a Radiometer pH-STAT.) The Nao-sensitive efflux of Nai was found to be 1.95 +/- 0.10 times the Nao-sensitive efflux of (SO4)i, indicating that the stoichiometry of this cotransport is two Na+ per SO4=, accounting for 60-80% of the electroneutral Na efflux. The remainder portion, that is, the ouabain-sensitive Nao-insensitive component, has been identified as PO4-coupled Na transport and is the subject of a separate paper. That uncoupled Na efflux occurs as a cotransport with anions is supported by the result, obtained with resealed ghosts, that when internal and external SO4 was substituted by the impermeant anion, tartrate i,o, the efflux of Na was inhibited 60-80%. This inhibition could be relieved by the inclusion, before DIDS treatment, of 5 mM Cli,o

  10. Na/K pump inactivation, subsarcolemmal Na measurements, and cytoplasmic ion turnover kinetics contradict restricted Na spaces in murine cardiac myocytes.

    Science.gov (United States)

    Lu, Fang-Min; Hilgemann, Donald W

    2017-07-03

    Decades ago, it was proposed that Na transport in cardiac myocytes is modulated by large changes in cytoplasmic Na concentration within restricted subsarcolemmal spaces. Here, we probe this hypothesis for Na/K pumps by generating constitutive transsarcolemmal Na flux with the Na channel opener veratridine in whole-cell patch-clamp recordings. Using 25 mM Na in the patch pipette, pump currents decay strongly during continuous activation by extracellular K (τ, ∼2 s). In contradiction to depletion hypotheses, the decay becomes stronger when pump currents are decreased by hyperpolarization. Na channel currents are nearly unchanged by pump activity in these conditions, and conversely, continuous Na currents up to 0.5 nA in magnitude have negligible effects on pump currents. These outcomes are even more pronounced using 50 mM Li as a cytoplasmic Na congener. Thus, the Na/K pump current decay reflects mostly an inactivation mechanism that immobilizes Na/K pump charge movements, not cytoplasmic Na depletion. When channel currents are increased beyond 1 nA, models with unrestricted subsarcolemmal diffusion accurately predict current decay (τ ∼15 s) and reversal potential shifts observed for Na, Li, and K currents through Na channels opened by veratridine, as well as for Na, K, Cs, Li, and Cl currents recorded in nystatin-permeabilized myocytes. Ion concentrations in the pipette tip (i.e., access conductance) track without appreciable delay the current changes caused by sarcolemmal ion flux. Importantly, cytoplasmic mixing volumes, calculated from current decay kinetics, increase and decrease as expected with osmolarity changes (τ >30 s). Na/K pump current run-down over 20 min reflects a failure of pumps to recover from inactivation. Simulations reveal that pump inactivation coupled with Na-activated recovery enhances the rapidity and effectivity of Na homeostasis in cardiac myocytes. In conclusion, an autoregulatory mechanism enhances cardiac Na/K pump activity when

However, during intense contraction some Na(+)-K(+) pumps are inactivated and together with further ionic disturbances, likely precipitate muscle fatigue.......Membrane excitability is a critical regulatory step in skeletal muscle contraction and is modulated by local ionic concentrations, conductances, ion transporter activities, temperature, and humoral factors. Intense fatiguing contractions induce cellular K(+) efflux and Na(+) and Cl(-) influx......, causing pronounced perturbations in extracellular (interstitial) and intracellular K(+) and Na(+) concentrations.

    Metallic Na was formed in NaCl single crystals with irradiation of a variety of radiation sources and analyzed the physical states with several methods. In the case of irradiation of 21 MeV electron pulses to the crystal blocks, the optical absorption and lifetime measurement of positron annihilation indicated appearance of Na clusters inside. Radiation effects of electron beam of 30 keV to the crystals in vacuum showed the appearance of not only metallic Na but atomic one during irradiation with Auger electron spectroscopy. Intense photon fluxes in vacuum ultraviolet region of synchrotron radiation were used as another source and an analyzing method of ultraviolet photoelectron spectroscopy. The results showed the metallic Na layered so thick that bulk plasmon can exist. (author)

    We have used the pulsed muon source at ISIS to study high-temperature Na-ion dynamics in the quasi-one-dimensional (Q1D) metallic antiferromagnet NaV 2 O 4 . By performing systematic zero-field and longitudinal-field measurements as a function of temperature we clearly distinguish that the hopping rate increases exponentially above T diff ≈ 250 K. The data is well fitted to an Arrhenius type equation typical for a diffusion process, showing that the Na-ions starts to be mobile above T diff . Such results make this compound very interesting for the tuning of Q1D magnetism using atomic-scale ion-texturing through the periodic potential from ordered Na-vacancies. Further, it also opens the door to possible use of NaV 2 O 4 and related compounds in energy related applications

We compare this observation with previous summer measurements and find a frequent appearance of Na number density enhancements near local midnight. We describe the time of appearance, the altitude distribution, the duration and the strength of these enhancements and compare them to winter observations. We investigate possible formation mechanisms and, as others before, we find a strong link between these Na number density enhancements and sporadic E layers.

    High surface area in h-WO3 has been verified from the intracrystalline tunnels. This bottom-up approach differs from conventional templating-type methods. The 3.67 Å diameter tunnels are characterized by low-pressure CO2 adsorption isotherms with nonlocal density functional theory fitting, transmission electron microscopy, and thermal gravimetric analysis. These open and rigid tunnels absorb H(+) and Li(+), but not Na(+) in aqueous electrolytes without inducing a phase transformation, accessing both internal and external active sites. Moreover, these tunnel structures demonstrate high specific pseudocapacitance and good stability in an H2SO4 aqueous electrolyte. Thus, the high surface area created from 3.67 Å diameter tunnels in h-WO3 shows potential applications in electrochemical energy storage, selective ion transfer, and selective gas adsorption.

    This paper addresses the question of long-range interactions between the intramembranous cation binding sites and the cytoplasmic nucleotide binding site of the ubiquitous ion-transporting Na,K-ATPase using (13)C cross-polarization magic-angle spinning (CP-MAS) solid-state nuclear magnetic resonance. High-affinity ATP binding is induced by the presence of Na(+) as well as of Na-like substances such as Tris(+), and these ions are equally efficient promoters of nucleotide binding. CP-MAS analysis of bound ATP with Na,K-ATPase purified from pig kidney membranes reveals subtle differences in the nucleotide interactions within the nucleotide site depending on whether Na(+) or Tris(+) is used to induce binding. Differences in chemical shifts for ATP atoms C1' and C5' observed in the presence of Na(+) or Tris(+) suggest alterations in the residues surrounding the bound nucleotide, hydrogen bonding, and/or conformation of the ribose ring. This is taken as evidence of a long-distance communication between the Na(+)-filled ion sites in the membrane interior and the nucleotide binding site in the cytoplasmic domain and reflects the first conformational change ultimately leading to phosphorylation of the enzyme. Stopped-flow fluorescence measurements with the nucleotide analogue eosin show that the dissociation rate constant for eosin is larger in Tris(+) than in Na(+), giving kinetic evidence of the difference in structural effects of Na(+) and Tris(+). According to the recent crystal structure of the E1·AlF4(-)·ADP·3Na(+) form, the coupling between the ion binding sites and the nucleotide side is mediated by, among others, the M5 helix.

    This special section on theoretical and computational nano-photonics features papers presented at the first International Workshop on Theoretical and Computational Nano-Photonics (TaCoNa-Photonics 2008) held in Bad Honnef, Germany, 3-5 December 2008. The workshop covered a broad range of topics related to current developments and achievements in this interdisciplinary area of research. Since the late 1960s, the word `photonics' has been understood as the science of generating, controlling, and detecting light. Nowadays, a routine fabrication of complex structures with micro- and nano-scale dimensions opens up many new and exciting possibilities in photonics. The science of generating, routing and detecting light in micro- and nano-structured matter, `nano-photonics', is becoming more important both in research and technology and offers many promising applications. The inherently sub-wavelength character of the structures that nano-photonics deals with challenges modern theoretical and computational physics and engineering with many nontrivial questions: Up to what length-scale can one use a macroscopic phenomenological description of matter? Where is the interface between the classical and quantum description of light in nano-scale structures? How can one combine different physical systems, different time- and length-scales in a single computational model? How can one engineer nano-structured materials in order to achieve the desired optical properties for particular applications? Any attempt at answering these kinds of questions is impossible without the joint efforts of physicists, engineers, applied mathematicians and programmers. This is the reason why the major goal of the TaCoNa-Photonics workshops is to provide a forum where theoreticians and specialists in numerical methods from all branches of physics, engineering sciences and mathematics can compare their results, report on novel results and breakthroughs, and discuss new challenges ahead.

    The main physics goals of the NA61/SHINE programme on strong interactions are the study of the properties of the onset of deconfinement and the search for signatures of the critical point of strongly interacting matter. These goals are pursued by performing an energy (beam momentum 13A -158A GeV/c) and system size (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La) scan. This publication reviews results and plans of NA61/SHINE. In particular, recent inclusive spectra and new results on fluctuations and correlations of identified hadrons in inelastic p+p and centrality selected Be+Be interactions at the SPS energies are presented. The energy dependence of quantities inspired by the Statistical Model of the Early Stage (kink, horn and step) show unexpected behavior in p+p collisions. The NA61/SHINE results are compared with the corresponding data of other experiments and model predictions.

    The aim of the NA61/SHINE ion programme is to explore the QCD phase diagram within the range of thermodynamical variables accessible by the SPS. Moreover the experiment provides precision hadron production measurements to improve computation of neutrino fluxes in neutrino oscillation experiments and for improving air shower simulations of cosmic-ray experiments. The main physics goals of the NA61/SHINE ion programme are the study of the properties of the onset of deconfinement and the search for signatures of the critical point of strongly interacting matter. These goals are pursued by performing an energy (beam momentum 13A – 158 A GeV/c) and system size (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La) scan. This paper reviews the status and results of the NA61/SHINE experiment.

    The zeolites NaX, NaY, Zn(55)NaY, and Zn(74)NaY were investigated by means of carbon monoxide adsorption and with static and magic angle spinning (MAS) 23Na NMR spectroscopy. The Na+ distribution between the sodalite (ß)- and supercages of the fully hydrated zeolites NaX and NaY were found to agree with XRD results. In the hydrated zinc-exchanged zeolites the Na+ ions almost exclusively populate the ß-cages. The adsorption isotherms of CO in the dehydrated zeolites were analyzed quantitatively to yield the concentrations of Na+ residing in the supercages. The measured static and MAS 23Na NMR spectra were analyzed by comparing their widths and shapes with simulated central transition patterns and yield, inter alia, the concentrations of Na+ associated with the spectrum components. Arguments are put forward that 23Na NMR of dehydrated zeolites is well suited to distinguish Na+ cations in highly symmetric environments and mobile Na+ species from others located on general positions, but further resolution is hardly feasible.

    Full Text Available Socio-economic changes throughout history have shaped the attitude towards the forest and most significant ones are changes in terms of population. Over the centuries population and population density have had a significant impact on deforestation and the reduction of forest areas. Therefore, it is important to check what kind of trends are concerned and how population growth affects forest areas, forest cover and forest area per capita. These elements are important for assessing the direction, intensity of activity and the degree of success in the implementation of all forest policy measures in Serbia.

    Na(+),K(+)-ATPase pumps three Na(+) ions out of cells in exchange for two K(+) taken up from the extracellular medium per ATP molecule hydrolysed, thereby establishing Na(+) and K(+) gradients across the membrane in all animal cells. These ion gradients are used in many fundamental processes, notably excitation of nerve cells. Here we describe 2.8 Å-resolution crystal structures of this ATPase from pig kidney with bound Na(+), ADP and aluminium fluoride, a stable phosphate analogue, with and without oligomycin that promotes Na(+) occlusion. These crystal structures represent a transition state preceding the phosphorylated intermediate (E1P) in which three Na(+) ions are occluded. Details of the Na(+)-binding sites show how this ATPase functions as a Na(+)-specific pump, rejecting K(+) and Ca(2+), even though its affinity for Na(+) is low (millimolar dissociation constant). A mechanism for sequential, cooperative Na(+) binding can now be formulated in atomic detail.

  11. Glutathionylation-Dependence of Na(+)-K(+)-Pump Currents Can Mimic Reduced Subsarcolemmal Na(+) Diffusion.

    Science.gov (United States)

    Garcia, Alvaro; Liu, Chia-Chi; Cornelius, Flemming; Clarke, Ronald J; Rasmussen, Helge H

    2016-03-08

    The existence of a subsarcolemmal space with restricted diffusion for Na(+) in cardiac myocytes has been inferred from a transient peak electrogenic Na(+)-K(+) pump current beyond steady state on reexposure of myocytes to K(+) after a period of exposure to K(+)-free extracellular solution. The transient peak current is attributed to enhanced electrogenic pumping of Na(+) that accumulated in the diffusion-restricted space during pump inhibition in K(+)-free extracellular solution. However, there are no known physical barriers that account for such restricted Na(+) diffusion, and we examined if changes of activity of the Na(+)-K(+) pump itself cause the transient peak current. Reexposure to K(+) reproduced a transient current beyond steady state in voltage-clamped ventricular myocytes as reported by others. Persistence of it when the Na(+) concentration in patch pipette solutions perfusing the intracellular compartment was high and elimination of it with K(+)-free pipette solution could not be reconciled with restricted subsarcolemmal Na(+) diffusion. The pattern of the transient current early after pump activation was dependent on transmembrane Na(+)- and K(+) concentration gradients suggesting the currents were related to the conformational poise imposed on the pump. We examined if the currents might be accounted for by changes in glutathionylation of the β1 Na(+)-K(+) pump subunit, a reversible oxidative modification that inhibits the pump. Susceptibility of the β1 subunit to glutathionylation depends on the conformational poise of the Na(+)-K(+) pump, and glutathionylation with the pump stabilized in conformations equivalent to those expected to be imposed on voltage-clamped myocytes supported this hypothesis. So did elimination of the transient K(+)-induced peak Na(+)-K(+) pump current when we included glutaredoxin 1 in patch pipette solutions to reverse glutathionylation. We conclude that transient K(+)-induced peak Na(+)-K(+) pump current reflects the effect

    Factorial determination of the sodium (Na) requirement of heat-stressed lactating cows is hindered by accurate estimates of the Na losses through sweat. Direct studies, therefore, may be needed requiring information on the time course of healthy animals to become Na depleted and the subsequent rate of repletion. The rate of Na depletion and subsequent rate of Na repletion with two levels of dietary Na to lactating dairy cows housed under tropical conditions were investigated using the salivary Na/K. The 12 lactating cows (salivary Na/K ratio 14.6) rapidly developed clinical signs of Na deficiency, including pica, polyuria and polydipsia, reduced body weight and reduced milk yield when fed a low-Na ration (0.33 g kg -1 dry matter (DM)) for 3 weeks. Deficiency symptoms were associated with a rapid decrease in salivary Na/K ratio to cows with NaCl to a ration concentration of 1.1 or 1.6 g Na kg -1 DM for 5 weeks did not restore salivary Na/K ratio to values of >6. A daily Na intake of heat-stressed lactating cows to a ration intake of 1.6 g Na kg -1 DM was insufficient to restore Na deficiency. One week was sufficient to deplete heat-stressed lactating cows of Na, allowing for rapid dose-response studies utilizing the salivary Na/K ratio as a parameter for Na status of cows under tropical conditions. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    A part of the LKr calorimeter data acquisition system of the NA48 experiment (a precision measurements of epsilon / epsilon ' in CP- violating K/sup 0/ to 2 pi decays) is described. The experiment runs on the SPS north area in CERN. This paper presents some aspects of controlling the NA48 readout process based on commercial RIO 8260 RISC processors, which were used as a core for maintaining control algorithms. Several RISC processors were equipped with custom-made VME mezzanine boards providing interfacing, pre-processing and data formatting. These mezzanines are the subjects of this paper. They are: RIO-TIC/DAT (a time-stamp distributor and buffered DT-bus interface), FOL-RIO (an optical data formatter and event merger) and "TAXI receiver" (for handling trigger data of the NA48 Level-2 trigger supervisor). Also, the interface between the DT-bus and S- link/PCI is described. (8 refs).

    1961-01-01

    Many recent studies of solid-state phenomena, particularly in the area of crystal imperfections, have involved the use of melt-grown NaCl single crystals. Quite often trace impurities in these materials have had a prominent effect on these phenomena. Trace amounts of hydroxide ion have been found in melt-grown NaCl crystals. This paper describes a nondestructive method of neutralizing the hydroxide ion in such crystals. Crystals of similar hydroxide content are maintained at an elevated temperature below the melting point of NaCl in a flowing atmosphere containing. dry hydrogen chloride. Heat treatment is continued until an analysis of the test specimens shows no excess hydroxide ion. A colorimetric method previously described4 is used for this analysis.

    1996-01-01

    A new evaluation of pure NaI has been performed to determine if moderate cooling would lead to better performance than that of existing, activated NaI(Tl) position-sensitive detectors, particularly at high countrates. Using a freezer, an initial effort was performed to cool the crystal assembly to -90 C (183 K). At this temperature, pure NaI has a decay constant of 35 nsec, a light output which is about 20% that of room temperature NaI(Tl), and an energy resolution of 15%. For the PET applications the signal of room temperature (25 C) NaI(Tl) is normally pulse clipped, reducing the light output to 40% of the unclipped signal and yielding an energy resolution of 10.5%. Since the long decay of NaI(Tl) causes it to suffer more significantly than pure NaI from pre-pulse pileup, the difference in energy resolution between the two crystals at high countrates will be reduced. Also, a significantly shorter trigger deadtime with pure NaI will lead to a reduction in coincidence deadtime losses in PET. Computer simulations of large-area crystals operating at high countrates have been performed to quantify their trigger deadtime behavior and position resolution as a function of light output and pulse decay time. Having gained experience with the practical issues of cooling large crystals, measurements of position resolution have been performed with a NaI bar detector of similar geometry to the NaI(Tl) detectors in use in the PENN-PET scanner

    2003-08-01

    An overview of the current status of the Main Injector Neutrino Oscillation Search (MINOS) is presented. MINOS is a long-baseline experiment with two detectors situated in North America. The near detector is based at the emission point of the NuMI beam at Fermilab, Chicago, the far detector is 735 km downstream in a disused iron mine in Soudan, Minnesota. A third detector, the calibration detector, is used to cross-calibrate these detectors by sampling different particle beams at CERN. A detailed description of the design and construction of the light-injection calibration system is included. Also presented are experimental investigations into proton-carbon collisions at 158 GeV/c carried out with the NA49 experiment at CERN. The NA49 experiment is a Time Projection Chamber (TPC) based experiment situated at CERN's North Area. It is a well established experiment with well known characteristics. The data gained from this investigation are to be used to parameterize various hadronic production processes in accelerator and atmospheric neutrino production. These hadronic production parameters will be used to improve the neutrino generation models used in calculating the neutrino oscillation parameters in MINOS.

    This paper presents the results of synthesis of nanozeolite NaX from Vietnamese kaolin. Influence factors on the control of crystal sizes and application of synthesized materials as adsorbent for organic compound are discussed. The results show that there are several factors that influence the synthesis. When water content in gel increases, crystal size of NaX increases sharply. The increase of alkaline and silica contents increases the crystallinity and decreases the particle size of nano NaX, and the particle size reaches the minimum at Na 2 O/Al 2 O 3 = 5.0 and SiO 2 /Al 2 O 3 = 4.0. Crystal sizes formed at low crystallizing temperature are smaller than those formed at higher temperature. Ageing time and crystallizing time strongly influence the crystallinity and crystal size, which is related to the number of crystal seeds formed during ageing period, the growth of seed and the partial solubility of crystal at maximum formation. Nano NaX was characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Brunauer–Emmett–Teller (BET) adsorption, Fourier transform infrared (FTIR) and simultaneous thermogravimetry–differential scanning calorimetry (TG/DSC). At optimized synthesis conditions, nano NaX has surface area of 573 m 2 g −1 with external surface area of 92 m 2 g −1 , pore size distribution at 0.81 and 10.8 nm, average crystal size of 25 nm and thermal stability up to 789 °C. This material can adsorb cumene rapidly with high adsorption capacity and stability. (paper)

    Na/K pump activity and metabolic rate are both higher during the day in the suprachiasmatic nucleus (SCN) that houses the circadian clock. Here we investigated the role of intracellular Na(+) and energy metabolism in regulating Na/K pump activity and neuronal excitability. Removal of extracellular K(+) to block the Na/K pump excited SCN neurons to fire at higher rates and return to normal K(+) to reactivate the pump produced rebound hyperpolarization to inhibit firing. In the presence of tetrodotoxin to block the action potentials, both zero K(+)-induced depolarization and rebound hyperpolarization were blocked by the cardiac glycoside strophanthidin. Ratiometric Na(+) imaging with a Na(+)-sensitive fluorescent dye indicated saturating accumulation of intracellular Na(+) in response to pump blockade with zero K(+). The Na(+) ionophore monensin also induced Na(+) loading and hyperpolarized the membrane potential, with the hyperpolarizing effect of monensin abolished in zero Na(+) or by pump blockade. Conversely, Na(+) depletion with Na(+)-free pipette solution depolarized membrane potential but retained residual Na/K pump activity. Cyanide inhibition of oxidative phosphorylation blocked the Na/K pump to depolarize resting potential and increase spontaneous firing in most cells, and to raise intracellular Na(+) levels in all cells. Nonetheless, the Na/K pump was incompletely blocked by cyanide but completely blocked by iodoacetate to inhibit glycolysis, indicating the involvement of both oxidative phosphorylation and glycolysis in fueling the Na/K pump. Together, the results indicate the importance of intracellular Na(+) and energy metabolism in regulating Na/K pump activity as well as neuronal excitability in the SCN neurons.

    The NA48 Collaboration is rebuilding its drift chambers ready for the experiment to start up again this coming July. An intricate task involving the soldering of over 24,000 wires! The future of the NA48 experiment is coming right down to the wire, that is, the wires which the Collaboration is installing in the clean room of Hall 887 on the Prévessin site. Six days a week, technicians are working in shifts to rebuild the experiment's drift chambers. The original chambers were damaged when a section of a vacuum tube imploded at the end of 1999. A year ago, CERN gave the green light for this essential part of the spectrometer to be rebuilt, so the NA48 experiment, which studies CP violation (see box), still has a bright future ahead of it. Three years of data-taking ahead The NA48 experiment aims to penetrate the secrets of CP (Charge Parity) violation.

    Forty one patients of hyperthyroidism were treated with Na 131 I. Men and women are in the ratio 1:3.1. The ages of patients are between twenties and sixties and the forties are the highest in number. The observation period of clinical courses is between 1 and 8 years. The number of patients observed over 5 years are 51% of them and over 2 years are 83%. The treatment frequency is as follows: On 37 cases each one was treated once with Na 131 I. 2 cases twice, 1 case at 4 times in 3 years and 1 case at 5 times in 6 years. The treatment doses are between 4,000-6,000 rad (40-60 Gray). In the cases treated with the irradiation dose of 6,000 rad, we often saw hypothyroidism. In cases aiming 4,000-5,000 rad, there is a tendency of leaving hyperthyroidism unrecovered. In conclusion, the patients should be treated giving 4,000-5,000 rad or with Na 131 I doses of 3-6mCi. If the effects of the treatment are insufficient, the patients should be further treated with anti-thyroid drug or treated again with Na 131 I. As the result, there are at present 25 cases (61.0%) in normal status of the thyroid gland, 12 cases (29.2%) in hyperthyroidism and 4 cases (9.8%) in hypothyroidism totaling 41 cases in all.

    This study investigates whether early dynamic positron emission tomography/computed tomography (ed-PET/CT) using 18 F-sodium fluoride-( 18 F-NaF) is feasible in depicting early phases of radiotracer distribution in patients with chronic osteomyelitis (COM). A total of 12 ed 18 F-NaF-PET/CT examinations were performed on 11 consecutive patients (2 female, 9 male; age 53 ± 12 years) in list mode over 5 min starting with radiopharmaceutical injection before standard late 18 F-NaF-PET/CT. Eight consecutive time intervals (frames) were reconstructed for each patient: four 15 s, then four 60 s. Several volumes of interest (VOI) were selected, representing the affected area as well as different reference areas within the bone and soft tissue. Maximum and mean ed standardized uptake values (edSUV max , edSUV mean , respectively) were calculated in each VOI during each frame to measure early fluoride influx and accumulation. Results were compared between affected and non-affected (contralateral) bones. Starting in the 31-45 s frame, the affected bone area showed significantly higher edSUV max and edSUV mean compared to the healthy contralateral region. The affected bone areas also significantly differed from non-affected contralateral regions in conventional late 18 F-NaF-PET/CT. This pilot study suggests that, in patients with COM, ed 18 F-NaF-PET offers additional information about early radiotracer distribution to standard 18 F-NaF-PET/CT, similar to a three-phase bone scan. The results should be validated in larger trials which directly compare ed 18 F-NaF-PET to a three-phase bone scan. (author)
