    Steiner, John

    2015-02-01

    This paper is based on a talk given at the conference to celebrate the Work of Hanna Segal and attempts to summarise her contribution to psychoanalysis. I suggest that in addition to being the important presenter of the work of Melanie Klein, she made major contributions to our understanding of many analytic ideas, for example, symbol formation, the usefulness of the concept of the death instinct and the relation between phantasy and reality. She was a pioneer in the analytic treatment of psychosis and sh wrote important papers on literature and aesthetics. She was a great teacher and emphasised the central role played by the analytic setting in representing the attitude of the analyst. Copyright © 2014 Institute of Psychoanalysis.

    Full Text Available Floristic studies of a region have many advantages, since the floristic list is a useful identity document which provides the genetic potentials of the area. The area of Hanna no-hunting zone is 20452 ha and is located at the southern part of Isfahan province. In this study the floristic list of the region is presented and their life forms and endangered species are stated. Field data collections were conducted during the years 2007 through 2008. First the studied area boundaries were exposed on a topographic map with a scale of 1:25000. Then, the plant species of the region were collected and identified according to the floras. According to the presented list, there were 307 species belonging to 209 genuses which are classified in 51 families. The Asteraceae has the highest species diversity in the region with 33 genus and 52 species. According to Raunkiaer’s life form criteria, the identified species are categorized as: hemicryptophytes 50.5%, therophytes 23.1%, chamephytes 11.4%, phanerophytes (6.8% and geophytes (8.1%. The high percent occurrence of the perennial species confirms the plant species adaptations to the climatic and edaphic conditions of the region. In the Hanna region, 76 medicinal and industrial species were listed belonging to 67 genera and 29 families. The Asteraceae and Lamiaceae families had 12 and 13 species of the medicinal plant species accordingly and they had the most species diversities in this category among the other families. There were 9 vulnerable species, 28 lower risk and 4 data deficient species in the studied region.

  6. Contemporary art and Hanna Segal's thinking on aesthetics.

    Science.gov (United States)

    Abella, Adela

    2010-02-01

    From the point of view of the history of ideas in psychoanalysis, a major shift may be described from Freud's starting point considering art as sublimation of sexual desires on a largely objectal level to later developments emphasizing the presence in art of destructiveness and narcissistic conflicts. Segal's contribution represents a watershed in this evolution. Following Klein, Hanna Segal suggests considering art in relation to depressive anxieties and reparation in such a way that artistic activity may be seen as an attempt 'to restore and re-create the loved object outside and inside the ego' which implies a successful work of mourning accompanied by symbol formation. For Segal, these reparative processes are conveyed through formal beauty which represents the victory of reparation over destruction. Nevertheless, contemporary art demands that we consider the intervention, in art, of more raw and less symbolized/sublimated processes, including acting-out in often primitive, psychotic or perverse ways. Thus this paper unfolds in two directions: on the one hand, it examines the differences and continuities between Freud's and Segal's thinking whilst, on the other, the author presents some alternative ideas which stress the search for truth and new thinking in contemporary art.

    This second special issue on the ecosystem under the COMIDA (Chukchi Sea Offshore Monitoring in the Drilling Area) Project focuses on the productive region around Hanna Shoal, the northernmost shoal on the Chukchi shelf. Our first issue (Dunton et al., 2014) emphasized the chemical and biological characteristics of the northeastern Chukchi Sea benthos. This effort expands our studies on the unique physical oceanography of Hanna Shoal, which lies at the interface between northward flowing Pacific Water and the Arctic Ocean, to include its influence on zooplankton dynamics and higher trophic level biota. Between both studies, conducted over a 5-year period (2009-2013) and four summer cruises, COMIDA scientists from seven institutions occupied some 85 stations (Fig. 1).

  13. High resolution seismic survey of the Hanna, Wyoming underground coal gasification area

    Energy Technology Data Exchange (ETDEWEB)

    1982-01-01

    In November 1980 a high resolution seismic survey was conducted at the Department of Energy, Laramie Energy Technology Center's underground coal gasification test site near Hanna, Wyoming. The objectives of the survey were to determine the feasibility of utilizing high resolution seismic technology to locate and characterize underground coal burn zones and to identify shallow geologic faults at the test site. Seismic data acquisition and processing parameters were specifically designed to emphasize reflections at the shallow, 61 to 91 meter (200 to 300 foot) depths of interest. A three-dimensional grid of data was obtained over the Hanna II, Phases 2 and 3 burn zone. Processing included time varying filters, deconvolution, trace composition, and two-dimensional, areal stacking of the data in order to identify burn zone anomalies. An anomaly was clearly discernable resulting from the rubble-collapse void above the burn zone which was studied in detail and compared to synthetic models. It is felt, based on these results, that the seismic method can be used to define similar burns if great care is taken in both acquisition and processing phases of an investigation. The fault studies disclosed faults at the test site of hitherto unsuspected complexity. The fault system was found to be a graben complex with numerous antithetic faults. The antithetic faults also contain folded beds. One of the faults discovered may be responsible for the unexpected problems experienced in some of the early in-situ gasification tests at the site. A series of anomalies were discovered on the northeast end of one of the seismic lines, and these reflections have been identified as adits from the old Hanna No. 1 Coal Mine.

    The case of Hanna Porn affords an opportunity to examine how the laws that led to the abolition of midwifery in Massachusetts evolved and were applied to the midwife whose case set the state legal precedent. Mrs Porn served primarily a Finnish-Swedish clientele of wives of laborers. The outcomes of the births she attended appear to have been positive, and she maintained a neonatal mortality rate of less than half that of local physicians. She also repeatedly defied court orders to stop practicing. Her case exemplifies the efforts that occurred nationally to abolish midwifery in the United States. PMID:8203670

    Marcouiller, B.A.; Burns, L.K.; Ethridge, F.G.

    1984-11-01

    Analysis of 21 post-burn cores taken from the Hanna IV UCG site allows 96 m (315 ft) of overburden to be subdivided into four local stratigraphic units. The 7.6 m (25 ft) thick Hanna No. 1 coal seam is overlain by a laterally discontinuous, 3.3 m (11 ft) thick shaley mudstone (Unit A') in part of the Hanna IV site. A more widespread, 30 m (90 ft) thick well-indurated sandstone (Unit A) overlies the A' unit. Unit A is the roof rock for both of the Hanna IV cavities. Overlying Unit A is a 33 m (108 ft) thick sequence of mudstone and claystone (Unit B), and the uppermost unit at the Hanna IV site (Unit C) is a coarse-grained sandstone that ranges in thickness from 40 to 67 m (131 to 220 ft). Two elliptical cavities were formed during the two phases of the Hanna IV experiment. The larger cavity, Hanna IVa, is 45 x 15 m in plan and has a maximum height of 18 m (59 ft) from the base of the coal seam to the top of the cavity; the Hanna IVb cavity is 40 x 15 m in plan and has a maximum height of 11 m (36 ft) from the base of the coal seam to the top of the cavity. Geotechnical tests indicated that the Hanna IV overburden rocks were moderately strong to strong, based on the empirical classification of Broch and Franklin (1972), and a positive, linear correlation exists between rock strength and volume percent calcite cement. There is an inverse linear correlation between rock strength and porosity for the Hanna IV overburden rocks. 28 refs., 34 figs., 13 tabs..

    EVA objectives, procedures, and equipment for the Shuttle are reviewed. The EVA will occur as a planned excursion, to complete a mission objective, or on a contingency basis as support for the mission or to effect repairs to the Orbiter or its payload. Configurations for the placement of the airlock for EVA with and without Spacelab payloads are discussed, along with the various EVA tasks which could be expected as necessary for mission completion. Handholds have been placed in strategic positions on the RMS and along the payload doors, and a safety tether has been incorporated with line extension out to 25 ft. Off-the-shelf tools such as needlenose pliers, forceps, diagonal cutters, etc. are carried as standard equipment for the repair of malfunctioning equipment and doorlatches. Finally, attention is given to EVA lighting, communication, life-support, and work station restraint systems.

  19. EVA Performance Prediction

    2004-01-01

    Astronaut physical performance capabilities in micro gravity EV A or on planetary surfaces when encumbered by a life support suit and debilitated by a long exposure to micro gravity will be less than unencumbered pre flight capabilities. The big question addressed by human factors engineers is: what can the astronaut be expected to do on EVA or when we arrive at a planetary surface? A second question is: what aids to performance will be needed to enhance the human physical capability? These questions are important for a number of reasons. First it is necessary to carry out accurate planning of human physical demands to ensure that time and energy critical tasks can be carried out with confidence. Second it is important that the crew members (and their ground or planetary base monitors) have a realistic picture of their own capabilities, as excessive fatigue can lead to catastrophic failure. Third it is important to design appropriate equipment to enhance human sensory capabilities, locomotion, materials handling and manipulation. The evidence from physiological research points to musculoskeletal, cardiovascular and neurovestibular degradation during long duration exposure to micro gravity . The evidence from the biomechanics laboratory (and the Neutral Buoyancy Laboratory) points to a reduction in range of motion, strength and stamina when encumbered by a pressurized suit. The evidence from a long history of EVAs is that crewmembers are indeed restricted in their physical capabilities. There is a wealth of evidence in the literature on the causes and effects of degraded human performance in the laboratory, in sports and athletics, in industry and in other physically demanding jobs. One approach to this challenge is through biomechanical and performance modeling. Such models must be based on thorough task analysis, reliable human performance data from controlled studies, and functional extrapolations validated in analog contexts. The task analyses currently carried

    Endovascular sealing with the Nellix{sup ®} endoprosthesis (EVAS) is a new technique to treat infrarenal abdominal aortic aneurysms. We describe the use of endovascular sealing in conjunction with chimney stents for the renal arteries (chEVAS) in two patients, one with a refractory type Ia endoleak and an expanding aneurysm, and one with a large juxtarenal aneurysm unsuitable for fenestrated endovascular repair (EVAR). Both aneurysms were successfully excluded. Our report confirms the utility of chEVAS in challenging cases, where suprarenal seal is necessary. We suggest that, due to lack of knowledge on its durability, chEVAS should only been considered when more conventional treatment modalities (open repair and fenestrated EVAR) are deemed difficult or unfeasible.

    Hanna Shoal, in the northeastern Chukchi Sea, is potentially vulnerable to ecosystem disruption under ongoing climate change, however aspects of its ecology, particularly of its zooplankton, have been poorly understood. Mesozooplankton distribution, taxonomic composition, and abundance were described from across Hanna Shoal in August 2012 and 2013 as part of the multidisciplinary COMIDA Hanna Shoal Program. Zooplankton were collected using vertical tows of paired Bongo nets equipped with 150-μm and 500-μm mesh nets; samples from the 150-μm mesh nets were enumerated to identify and count taxa, copepod species, and copepod life stages. Haplotypes of the mitochondrial cytochrome c oxidase I (mtCOI) gene were used to differentiate Bering and Arctic haplotype groups of the copepod Calanus glacialis and to differentiate C. glacialis and its close congener C. marshallae. The meroplankton, particularly bivalve larvae and in 2012 echinoderm larvae, were an important component of the zooplankton and were of greater abundance on the eastern portion of the Shoal than elsewhere. Regions identified on the basis of different taxonomic compositions were associated with different water masses and current pathways. The northeast corner of the Shoal in particular was distinct from the remainder of the Shoal and from Barrow Canyon, with both different life stage compositions and unique Arctic haplotypes of the mtCOI gene for C. glacialis/marshallae, suggesting populations at those locations originated in the Arctic Ocean rather than the Bering Sea. Bering Sea Summer water, and intrinsic plankton, was observed in the southwest portion of the Shoal. Comparisons with historic and recent studies done near Hanna Shoal demonstrated that similar plankton compositions were present across a broad region of the Chukchi Sea and that abundances of the copepod C. glacialis appear to be increasing on the time scale of decades, potentially through increased input from the northern Bering Sea

  7. Analysis of conduction responses during an underground coal gasification experiment. [Hanna II

    Energy Technology Data Exchange (ETDEWEB)

    Hommert, P.J.

    1978-01-01

    The Laramie Energy Research Center (LERC) conducted an underground coal gasification experiment in a 9-m thick subbituminous coal seam near Hanna, Wyoming. Sandia Laboratories designed and fielded an extensive instrumentation array which included approximately eight thermocouples within the seam in each of 15 diagnostic wells. The instrumentation provided thermal data related to the process during both reverse combustion linkage and forward gasification. Portions of these data suitable for analysis by inverse heat conduction techniques included (1) the responses from the approximately cylindrical reverse combustion linkage path and (2) the responses at thermocouples outside the gasified zone due to conduction from the final boundary. Because of the effects of property variations and water vaporization on the conduction response, an exact analytical solution could not be used. Instead, the approach was to adjust parameters of the constant property analytical solutions to fit numerical calculations that included property variations and water vaporization. Sensitivity studies performed to estimate the accuracy of solutions obtained indicated that parameters relating to size and distance should be identifiable within +- 0.25 m; however, accurate estimates of temperature could not be obtained. Results allowed the position of the reverse combustion linkage path to be mapped, and estimates of its size (approximately 1 m in diameter) and average temperature (750 K--1000 K) to be obtained. With respect to forward gasification, the analysis yielded estimates of the final boundaries established by the burn and characterizations of how the front approached its final position.

    Performance of Extra-Vehicular Activities (EVA) has been and will continue to be a critical capability for human space flight. Human exploration missions beyond LEO will require EVA capability for either contingency or nominal activities to support mission objectives and reduce mission risk. EVA systems encompass a wide array of products across pressure suits, life support systems, EVA tools and unique spacecraft interface hardware (i.e. EVA Translation Paths and EVA Worksites). In a fiscally limited environment with evolving transportation and habitation options, it is paramount that the EVA community's strategic planning and architecture integration products be reviewed and vetted for traceability between the mission needs far into the future to the known technology and knowledge gaps to the current investments across EVA systems. To ascertain EVA technology and knowledge gaps many things need to be brought together, assessed and analyzed. This includes an understanding of the destination environments, various mission concept of operations, current state of the art of EVA systems, EVA operational lessons learned, and reference advanced capabilities. A combined assessment of these inputs should result in well-defined list of gaps. This list can then be prioritized depending on the mission need dates and time scale of the technology or knowledge gap closure plan. This paper will summarize the current state of EVA related technology and knowledge gaps derived from NASA's Exploration EVA Reference Architecture and Operations Concept products. By linking these products and articulating NASA's approach to strategic development for EVA across all credible destinations an EVA could be done in, the identification of these gaps is then used to illustrate the tactical and strategic planning for the EVA technology development portfolio. Finally, this paper illustrates the various "touch points" with other human exploration risk identification areas including human health and

    As NASA embarks upon developing the Next-Generation Extra Vehicular Activity (EVA) Radio for deep space exploration, the demands on EVA battery life will substantially increase. The number of modes and frequency bands required will continue to grow in order to enable efficient and complex multi-mode operations including communications, navigation, and tracking applications. Whether conducting astronaut excursions, communicating to soldiers, or first responders responding to emergency hazards, NASA has developed an innovative, affordable, miniaturized, power-efficient software defined radio that offers unprecedented power-efficient flexibility. This lightweight, programmable, S-band, multi-service, frequency- agile EVA software defined radio (SDR) supports data, telemetry, voice, and both standard and high-definition video. Features include a modular design, an easily scalable architecture, and the EVA SDR allows for both stationary and mobile battery powered handheld operations. Currently, the radio is equipped with an S-band RF section. However, its scalable architecture can accommodate multiple RF sections simultaneously to cover multiple frequency bands. The EVA SDR also supports multiple network protocols. It currently implements a Hybrid Mesh Network based on the 802.11s open standard protocol. The radio targets RF channel data rates up to 20 Mbps and can be equipped with a real-time operating system (RTOS) that can be switched off for power-aware applications. The EVA SDR's modular design permits implementation of the same hardware at all Network Nodes concept. This approach assures the portability of the same software into any radio in the system. It also brings several benefits to the entire system including reducing system maintenance, system complexity, and development cost.

  10. Dissolved methane concentrations in the water column and surface sediments of Hanna Shoal and Barrow Canyon, Northern Chukchi Sea

    Current estimates of methane (CH4) flux suggest that Arctic shelves may be a significant source of atmospheric CH4, a potent greenhouse gas. However, little information is known about the CH4 flux from most Arctic shelves, other than the East Siberian Arctic Shelf. We report here dissolved CH4 concentrations in the water column and within surface sediments of the Northern Chukchi Sea. We hypothesized that this area contains high concentrations of CH4 because it receives nutrient rich waters through the Bering Strait, promoting primary production that enhances an organic-rich material flux to the seafloor and eventual microbial methanogenesis in the sediments. In August 2012, as part of the Chukchi Sea Offshore Monitoring in Drilling Area (COMIDA) project, fourteen stations were sampled on Hanna Shoal, a shallow feature on the shelf, and ten stations across the undersea Barrow Canyon. On Hanna Shoal, water column CH4 concentrations ranged from 14 to 74 nM, and surface concentrations were up to 15 times supersaturated in CH4 compared to equilibrium with the average atmospheric concentrations (3 nM). CH4 concentrations at the sediment-water interface were around 1,500 nM, and typically increased with depth in the sediment. At the head of Barrow Canyon, water column CH4 concentrations ranged from 5 to 46 nM, with the highest concentrations in the deepest waters that were sampled (118 m). Overall, the calculated fluxes to the atmosphere ranged from 1 to 80 μmol CH4 m-2 d-1 for Hanna Shoal and 4 to 17 μmol CH4 m-2 d-1 across the Barrow Canyon stations. Although there was a large range in these fluxes, the average atmospheric flux (20 μmol CH4 m-2 d-1) across Hanna Shoal was 12 times lower than the flux reported from the East Siberian Arctic Shelf in summer. We conclude that while there is a positive flux of CH4 to the atmosphere, this part of the Chukchi Sea is not a significant source of atmospheric CH4 compared to the East Siberian Sea shelf.

  16. EVA Wiki - Transforming Knowledge Management for EVA Flight Controllers and Instructors

    2016-01-01

    The EVA Wiki was recently implemented as the primary knowledge database to retain critical knowledge and skills in the EVA Operations group at NASA's Johnson Space Center by ensuring that information is recorded in a common, easy to search repository. Prior to the EVA Wiki, information required for EVA flight controllers and instructors was scattered across different sources, including multiple file share directories, SharePoint, individual computers, and paper archives. Many documents were outdated, and data was often difficult to find and distribute. In 2011, a team recognized that these knowledge management problems could be solved by creating an EVA Wiki using MediaWiki, a free and open-source software developed by the Wikimedia Foundation. The EVA Wiki developed into an EVA-specific Wikipedia on an internal NASA server. While the technical implementation of the wiki had many challenges, one of the biggest hurdles came from a cultural shift. Like many enterprise organizations, the EVA Operations group was accustomed to hierarchical data structures and individually-owned documents. Instead of sorting files into various folders, the wiki searches content. Rather than having a single document owner, the wiki harmonized the efforts of many contributors and established an automated revision controlled system. As the group adapted to the wiki, the usefulness of this single portal for information became apparent. It transformed into a useful data mining tool for EVA flight controllers and instructors, as well as hundreds of others that support EVA. Program managers, engineers, astronauts, flight directors, and flight controllers in differing disciplines now have an easier-to-use, searchable system to find EVA data. This paper presents the benefits the EVA Wiki has brought to NASA's EVA community, as well as the cultural challenges it had to overcome.

  17. Eva Luna: Writing as History

    Directory of Open Access Journals (Sweden)

    Lynne Diamond-Nigh

    1995-01-01

    Full Text Available The Bildungsroman of Eva Luna's development as a writer reflects—in a somewhat fragmented manner—important developments in Latin American literary history. Her personal quest was paralleled by an aesthetic quest, manifested in the trying on and taking off of various genres, literary movements and myths characteristic of Latin America; she even goes so far as to allude explicitly to specific authors and their individual works. Although some of these are simply lightheartedly parodied, others are reworked and reinterpreted in the light of the feminist enterprise of the past twenty-five years. Eva Luna transgresses fundamentally by having an intellectually strong, sexual, nurturing, very feminine protagonist, setting up an initial rupture with the dichotomy so clearly demarcated by Octavio Paz between "the mother and the whore." Four primary categories suggest themselves: myth and the mythic consciousness; magical realism; Boom writers; and then a miscellaneous grouping that subsumes a host of other significant literatures and literary themes: the picaresque, the neo-romantic, novels of the dictators, the ever-present conflict between civilization and barbarism, and testimonial literature.

    The objective of this project is to collect microbial samples from various EVA suits to determine how much microbial contamination is typically released during simulated planetary exploration activities. Data will be released to the planetary protection and science communities, and advanced EVA system designers. In the best case scenario, we will discover that very little microbial contamination leaks from our current or prototype suit designs, in the worst case scenario, we will identify leak paths, learn more about what affects leakage--and we'll have a new, flight-certified swab tool for our EVA toolbox.

    McTigue, N. D.; Dunton, K. H.

    2017-10-01

    Predicting how alterations in sea ice-mediated primary production will impact Arctic food webs remains a challenge in forecasting ecological responses to climate change. One top-down approach to this challenge is to elucidate trophic roles of consumers as either specialists (i.e., consumers of predominantly one food resource) or generalists (i.e., consumers of multiple food resources) to categorize the dependence of consumers on each primary producer. At Hanna Shoal in the Chukchi Sea, Alaska, we used stable carbon and nitrogen isotope data to quantify trophic redundancy with standard ellipse areas at both the species and trophic guild levels. We also investigated species-level trophic plasticity by analyzing the varying extents that three end-members were assimilated by the food web using the mixing model simmr (Stable Isotope Mixing Model in R). Our results showed that ice algae, a combined phytoplankton and sediment organic matter composite (PSOM), and a hypothesized microphytobenthos (MPB) component were incorporated by consumers in the benthic food web, but their importance varied by species. Some primary consumers relied heavily on PSOM (e.g, the amphipods Ampelisca sp. and Byblis sp.; the copepod Calanus sp.), while others exhibited generalist feeding and obtained nutrition from multiple sources (e.g., the holothuroidean Ocnus glacialis, the gastropod Tachyrhynchus sp., the sipunculid Golfingia margaritacea, and the bivalves Ennucula tenuis, Nuculana pernula, Macoma sp., and Yoldia hyperborea). Most higher trophic level benthic predators, including the gastropods Buccinum sp., Cryptonatica affinis, and Neptunea sp, the seastar Leptasterias groenlandica, and the amphipod Anonyx sp. also exhibited trophic plasticity by coupling energy pathways from multiple primary producers including PSOM, ice algae, and MPB. Our stable isotope data indicate that consumers in the Hanna Shoal food web exhibit considerable trophic redundancy, while few species were specialists

    Multiple HRP Risks and Gaps require detailed characterization of human health and performance during exploration extravehicular activity (EVA) tasks; however, a rigorous and comprehensive methodology for characterizing and comparing the health and human performance implications of current and future EVA spacesuit designs does not exist. This study will identify and implement functional tasks and metrics, both objective and subjective, that are relevant to health and human performance, such as metabolic expenditure, suit fit, discomfort, suited postural stability, cognitive performance, and potentially biochemical responses for humans working inside different EVA suits doing functional tasks under the appropriate simulated reduced gravity environments. This study will provide health and human performance benchmark data for humans working in current EVA suits (EMU, Mark III, and Z2) as well as shirtsleeves using a standard set of tasks and metrics with quantified reliability. Results and methodologies developed during this test will provide benchmark data against which future EVA suits, and different suit configurations (eg, varied pressure, mass, CG) may be reliably compared in subsequent tests. Results will also inform fitness for duty standards as well as design requirements and operations concepts for future EVA suits and other exploration systems.

    There is a lack of information on aquifer dynamics in anchialine systems, especially in the Yucatán Peninsula of Mexico. Most of our knowledge is based on ;spot; measurements of the aquifer with no long-term temporal monitoring. In this study spanning four years (2012-2016), sensors (water depth and conductivity (salinity)) were deployed and positioned (-9 and -10 m) in the meteoric Water Mass (WM) close to the transition with the marine WM (halocline) in 2 monitoring sites within the Yax Chen cave system to investigate precipitation effects on the salinity of the coastal aquifer. The results show variation in salinity (95 mm) such as Hurricane Ingrid (2013) and Tropical Storm Hanna (2014) shows meteoric water mass salinity rapidly increasing (approx. 6.39 to >8.6 ppt), but these perturbations have a shorter duration (weeks and days). Wavelet analysis of the salinity record indicates seasonal mixing effects in agreement with the wet and dry periods, but also seasonal effects of tidal mixing (meteoric and marine water masses) occurring on shorter time scales (diurnal and semi-diurnal). These results demonstrate that the salinity of the freshwater lens is influenced by precipitation and turbulent mixing with the marine WM. The salinity response is scaled with precipitation; larger more intense rainfall events (>95 mm) create a larger response in terms of the magnitude and duration of the salinity perturbation (>1 ppt). The balance of precipitation and its intensity controls the temporal and spatial patterning of meteoric WM salinity.

    We are planning to build Evryscopes for the Arctic and Antarctic (EVA), which will enable the first ultra-wide-field, high-cadence sky survey to be conducted from both Poles. The system is based on the successful Evryscope concept, already installed and operating since 2015 at Cerro Tololo in Chile with the following characteristics: robotic operation, 8,000 square degrees simultaneous sky coverage, 2-minute cadence, milli-mag level photometric accuracy, pipelined data processing for real-time analysis and full data storage for off-line analysis. The initial location proposed for EVA is the PEARL station on Ellesmere island; later also an antarctic location shall be selected. The science goals enabled by this unique combination of almost full-sky coverage and high temporal cadence are numerous, and include among others ground-breaking forays in the fields of exoplanets, stellar variability, asteroseismology, supernovae and other transient events. The EVA polar locations will enable uninterrupted observations lasting in principle over weeks and months. EVA will be fully robotic. We discuss the EVA science drivers and expected results, and present the logistics and the outline of the project which is expected to have first light in the winter of 2018. The cost envelope can be kept very competitive thanks to R&D already employed for the CTIO Evryscope, to our experience with both Arctic and Antarctic locations, and to the use of off-the-shelf components.

    Rucker, Michelle A.

    2016-01-01

    When we send humans to search for life on Mars, we'll need to know what we brought with us versus what may already be there. To ensure our crewed spacecraft meet planetary protection requirements—and to protect our science from human contamination—we'll need to know whether micro-organisms are leaking/venting from our ships and spacesuits. This is easily done by swabbing external vents and suit surfaces for analysis, but requires a specialized tool for the job. Engineers at the National Aeronautics and Space Administration (NASA) recently developed an Extravehicular Activity (EVA)-compatible swab tool that can be used to sample current space suits and life support systems. Data collected now will influence Mars life support and EVA hardware early in the planning process, before design changes become difficult and expensive.NASA’s EVA swab tool pairs a Space Shuttle-era tool handle with a commercially available swab tip mounted into a custom-designed end effector. A glove-compatible release mechanism allows the handle to quickly switch between swab tips, much like a shaving razor handle can snap onto a disposable blade cartridge. Swab tips are stowed inside individual sterile containers, each fitted with a microbial filter that allows the container to equalize atmospheric pressure, but prevents cabin contaminants from rushing into the container when passing from the EVA environment into a pressurized cabin. A bank of containers arrayed inside a tool caddy allows up to six individual samples to be collected during a given spacewalk.NASA plans to use the tool in 2016 to collect samples from various spacesuits during ground testing to determine what (if any) human-borne microbial contamination leaks from the suit under simulated thermal vacuum conditions. Next, the tool will be used on board the International Space Station to assess the types of microbial contaminants found on external environmental control and life support system vents. Data will support

  19. A Human Machine Interface for EVA

    Science.gov (United States)

    Hartmann, L.

    EVA astronauts work in a challenging environment that includes high rate of muscle fatigue, haptic and proprioception impairment, lack of dexterity and interaction with robotic equipment. Currently they are heavily dependent on support from on-board crew and ground station staff for information and robotics operation. They are limited to the operation of simple controls on the suit exterior and external robot controls that are difficult to operate because of the heavy gloves that are part of the EVA suit. A wearable human machine interface (HMI) inside the suit provides a powerful alternative for robot teleoperation, procedure checklist access, generic equipment operation via virtual control panels and general information retrieval and presentation. The HMI proposed here includes speech input and output, a simple 6 degree of freedom (dof) pointing device and a heads up display (HUD). The essential characteristic of this interface is that it offers an alternative to the standard keyboard and mouse interface of a desktop computer. The astronaut's speech is used as input to command mode changes, execute arbitrary computer commands and generate text. The HMI can respond with speech also in order to confirm selections, provide status and feedback and present text output. A candidate 6 dof pointing device is Measurand's Shapetape, a flexible "tape" substrate to which is attached an optic fiber with embedded sensors. Measurement of the modulation of the light passing through the fiber can be used to compute the shape of the tape and, in particular, the position and orientation of the end of the Shapetape. It can be used to provide any kind of 3d geometric information including robot teleoperation control. The HUD can overlay graphical information onto the astronaut's visual field including robot joint torques, end effector configuration, procedure checklists and virtual control panels. With suitable tracking information about the position and orientation of the EVA suit

    2010-01-01

    Beginning in Fiscal Year (FY) 2011, Extravehicular activity (EVA) technology development became a technology foundational domain under a new program Enabling Technology Development and Demonstration. The goal of the EVA technology effort is to further develop technologies that will be used to demonstrate a robust EVA system that has application for a variety of future missions including microgravity and surface EVA. Overall the objectives will be reduce system mass, reduce consumables and maintenance, increase EVA hardware robustness and life, increase crew member efficiency and autonomy, and enable rapid vehicle egress and ingress. Over the past several years, NASA realized a tremendous increase in EVA system development as part of the Exploration Technology Development Program and the Constellation Program. The evident demand for efficient and reliable EVA technologies, particularly regenerable technologies was apparent under these former programs and will continue to be needed as future mission opportunities arise. The technological need for EVA in space has been realized over the last several decades by the Gemini, Apollo, Skylab, Space Shuttle, and the International Space Station (ISS) programs. EVAs were critical to the success of these programs. Now with the ISS extension to 2028 in conjunction with a current forecasted need of at least eight EVAs per year, the EVA technology life and limited availability of the EMUs will become a critical issue eventually. The current Extravehicular Mobility Unit (EMU) has vastly served EVA demands by performing critical operations to assemble the ISS and provide repairs of satellites such as the Hubble Space Telescope. However, as the life of ISS and the vision for future mission opportunities are realized, a new EVA systems capability could be an option for the future mission applications building off of the technology development over the last several years. Besides ISS, potential mission applications include EVAs for

    2002-12-01

    Full Text Available Olševa consists of highly pervious carbonates, forming a relatively big fractured and karstified aquifer. Due to its high-altitude mountainous nature, the aquifer is unpolluted and therefore has to be regarded as a potential source of drinking water for the future.The Olševa aquifer is tectonically divided into three parts. Groundwater from the two smaller aquifers, covering areas of 1,9 and 0,8 km2, located in eastern part of Ol{eva massif, flows toward Northeast into Meža river basin. In spite of several transversal faults, the rest of Olševa massif forms a relatively uniform aquifer that is conveying groundwater in westerly direction towards Rjavica valley. Rjavica valley in Austria represents the discharge area of a majority of groundwater from the main Ol{eva aquifer.

    1983-01-01

    On May 7th-9th, 1945, a team of Russian pathologists autopsied several bodies found in and near the Fuehrer Bunker in Berlin; among them, a female body (No. 13) was later identified as that of Eva Braun Hitler (EBH), mainly by means of a gold bridge from the lower right jaw. A postmortem photograph of this bridge also shows a separate gold filling. Data now available on the dental treatment of EBH have permitted the present authors to substantiate that this gold filling also came from the mouth of EBH. Further speculation about the fate of EBH would henceforth seem professionally unfounded.

    Financial institutions are interested in ensuring security and quality for their customers. Banks, for instance, need to identify and stop harmful transactions in a timely manner. In order to detect fraudulent operations, data mining techniques and customer profile analysis are commonly used. However, these approaches are not supported by Visual Analytics techniques yet. Visual Analytics techniques have potential to considerably enhance the knowledge discovery process and increase the detection and prediction accuracy of financial fraud detection systems. Thus, we propose EVA, a Visual Analytics approach for supporting fraud investigation, fine-tuning fraud detection algorithms, and thus, reducing false positive alarms.

  9. Effect of EVA on thermal stability, flammability, mechanical properties of HDPE/EVA/Mg(OH)2 composites

    Cao, R.; Deng, Z. L.; Ma, Y. H.; Chen, X. L.

    2017-06-01

    In this work, ethylene vinyl acetate (EVA) is introduced to improve the properties of high-density polyethylene (HDPE)/magnesium hydroxide (MH) composites. The thermal stability, flame retardancy and mechanical properties of HDPE/EVA/MH composites are investigated and discussed. With increasing content of EVA, the limiting oxygen index (LOI) of the composites increases. The thermal stability analysis shows that the initial decomposition temperature begins at a low temperature; however, the residues of the composites at 600°C increase when HDPE is replaced by small amounts of EVA. The early degradation absorbs heat, dilute oxygen and residue. During this process, it protects the matrix inside. Compared with the HDPE/MH and EVA/MH composites, the ternary HDPE/EVA/MH composites exhibit better flame retardancy by increasing the LOI values, and reducing the heat release rate (HRR) and total heat release (THR). With increasing content of EVA, the mechanical properties can also be improved, which is attributed to the good affinity between EVA and MH particles.

    Heat shrinkage of electron beam modified ethylene vinyl acetate copolymer (EVA) has been investigated over a range of times, temperatures, stretching, irradiation doses and trimethylolpropane trimethacrylate (TMPTMA) levels. The irradiated (radiation dose 50 kGy and TMPTMA level 1%) and stretched (100% elongation) sample shrinks to a maximum level when kept at 453K temperature for 60 s. The heat shrinkage of samples irradiated with radiation doses of 20, 50, 100 and 150 kGy increases sharply with increasing stretching in the initial stage. Amnesia rating decreases with increasing radiation dose and TMPTMA level as well as gel content. The high radiation dose and TMPTMA level lower the heat shrinkage due to the chain scission. The effect of temperature at which extension is carried out on heat shrinkage is marginal. The irradiated (radiation dose 50 kGy and TMPTMA level 1%) EVA tubes of different dimensions expanded in a laboratory grade tube expander show similar behaviour at 453K and 60 s. The X-ray and DSC studies reveal that the crystallinity increases on stretching due to orientation of chains and it decreases to a considerable extent on heat shrinking. The theoretical and experimental values of heat shrinkage for tubes and rectangular strips are in good accord, when the radiation dose is 50 kGy and TMPTMA level 1%. (author).

    Human missions to the Moon or Mars will likely be accompanied by many useful robots that will assist in all aspects of the mission, from construction to maintenance to surface exploration. Such robots might scout terrain, carry tools, take pictures, curate samples, or provide status information during a traverse. At NASA/JSC, the EVA Robotic Assistant (ERA) project has developed a robot testbed for exploring the issues of astronaut-robot interaction. Together with JSC's Advanced Spacesuit Lab, the ERA team has been developing robot capabilities and testing them with space-suited test subjects at planetary surface analog sites. In this paper, we describe the current state of the ERA testbed and two weeks of remote field tests in Arizona in September 2002. A number of teams with a broad range of interests participated in these experiments to explore different aspects of what must be done to develop a program for robotic assistance to surface EVA. Technologies explored in the field experiments included a fuel cell, new mobility platform and manipulator, novel software and communications infrastructure for multi-agent modeling and planning, a mobile science lab, an "InfoPak" for monitoring the spacesuit, and delayed satellite communication to a remote operations team. In this paper, we will describe this latest round of field tests in detail.

    The National Aeronautics and Space Administration (NASA) at the Johnson Space Center (JSC) is developing a new extra-vehicular activity (EVA) suit known as the Advanced EVA Z2 Suit. All of the improvements to the EVA Suit provide the opportunity to update the technology of the video imagery. My summer internship project involved improving the video streaming capabilities of the cameras that will be used on the Z2 Suit for data acquisition. To accomplish this, I familiarized myself with the architecture of the camera that is currently being tested to be able to make improvements on the design. Because there is a lot of benefit to saving space, power, and weight on the EVA suit, my job was to use Altium Design to start designing a much smaller and simplified interface board for the camera's microprocessor and external components. This involved checking datasheets of various components and checking signal connections to ensure that this architecture could be used for both the Z2 suit and potentially other future projects. The Orion spacecraft is a specific project that may benefit from this condensed camera interface design. The camera's physical placement on the suit also needed to be determined and tested so that image resolution can be maximized. Many of the options of the camera placement may be tested along with other future suit testing. There are multiple teams that work on different parts of the suit, so the camera's placement could directly affect their research or design. For this reason, a big part of my project was initiating contact with other branches and setting up multiple meetings to learn more about the pros and cons of the potential camera placements we are analyzing. Collaboration with the multiple teams working on the Advanced EVA Z2 Suit is absolutely necessary and these comparisons will be used as further progress is made for the overall suit design. This prototype will not be finished in time for the scheduled Z2 Suit testing, so my time was

  14. A Cabin Air Separator for EVA Oxygen

    Graf, John C.

    2011-01-01

    Presently, the Extra-Vehicular Activities (EVAs) conducted from the Quest Joint Airlock on the International Space Station use high pressure, high purity oxygen that is delivered to the Space Station by the Space Shuttle. When the Space Shuttle retires, a new method of delivering high pressure, high purity oxygen to the High Pressure Gas Tanks (HPGTs) is needed. One method is to use a cabin air separator to sweep oxygen from the cabin air, generate a low pressure/high purity oxygen stream, and compress the oxygen with a multistage mechanical compressor. A main advantage to this type of system is that the existing low pressure oxygen supply infrastructure can be used as the source of cabin oxygen. ISS has two water electrolysis systems that deliver low pressure oxygen to the cabin, as well as chlorate candles and compressed gas tanks on cargo vehicles. Each of these systems can feed low pressure oxygen into the cabin, and any low pressure oxygen source can be used as an on-board source of oxygen. Three different oxygen separator systems were evaluated, and a two stage Pressure Swing Adsorption system was selected for reasons of technical maturity. Two different compressor designs were subjected to long term testing, and the compressor with better life performance and more favorable oxygen safety characteristics was selected. These technologies have been used as the basis of a design for a flight system located in Equipment Lock, and taken to Preliminary Design Review level of maturity. This paper describes the Cabin Air Separator for EVA Oxygen (CASEO) concept, describes the separator and compressor technology trades, highlights key technology risks, and describes the flight hardware concept as presented at Preliminary Design Review (PDR)

Definition of design-to requirements is critical to understanding technical feasibility and costs. The definition of Planetary Protection needs in relation to EVA mission and system element development cost impacts should be considered and interpreted in terms of Plausible Protection criteria. Since EVA operations will have the most direct physical interaction with the Martian surface, PP needs should be considered in the terms of mitigating hardware and operations impacts and costs.

    2003-01-01

    The Robotic Systems Technology Branch is currently working on the development of an EVA Robotic Assistant under the sponsorship of the Surface Systems Thrust of the NASA Cross Enterprise Technology Development Program (CETDP). This will be a mobile robot that can follow a field geologist during planetary surface exploration, carry his tools and the samples that he collects, and provide video coverage of his activity. Prior experiments have shown that for such a robot to be useful it must be able to follow the geologist at walking speed over any terrain of interest. Geologically interesting terrain tends to be rough rather than smooth. The commercial mobile robot that was recently purchased as an initial testbed for the EVA Robotic Assistant Project, an ATRV Jr., is capable of faster than walking speed outside but it has no suspension. Its wheels with inflated rubber tires are attached to axles that are connected directly to the robot body. Any angular motion of the robot produced by driving over rough terrain will directly affect the pointing of the on-board stereo cameras. The resulting image motion is expected to make tracking of the geologist more difficult. This will either require the tracker to search a larger part of the image to find the target from frame to frame or to search mechanically in pan and tilt whenever the image motion is large enough to put the target outside the image in the next frame. This project consists of the design and implementation of a Kalman filter that combines the output of the angular rate sensors and linear accelerometers on the robot to estimate the motion of the robot base. The motion of the stereo camera pair mounted on the robot that results from this motion as the robot drives over rough terrain is then straightforward to compute. The estimates may then be used, for example, to command the robot s on-board pan-tilt unit to compensate for the camera motion induced by the base movement. This has been accomplished in two ways

    Eva-1 homolog A (EVA1A) is a novel lysosome and endoplasmic reticulum-associated protein involved in autophagy and apoptosis. In this study, we constructed a recombinant adenovirus 5-EVA1A vector (Ad5-EVA1A) to overexpress EVA1A in glioblastoma (GBM) cell lines and evaluated its anti-tumor activities in vitro and in vivo. We found that overexpression of EVA1A in three GBM cell lines (U251, U87 and SHG44) resulted in a suppression of tumor cell growth via activation of autophagy and induction of cell apoptosis in a dose- and time-dependent manner. EVA1A-mediated autophagy was associated with inactivation of the mTOR/RPS6KB1 signaling pathway. Furthermore in vivo, overexpression of EVA1A successfully inhibited tumor growth in NOD/SCID mice. Our data suggest that EVA1A-induced autophagy and apoptosis play a role in suppressing the development of GBM and their up-regulation may be an effective method for treating this form of cancer. - Highlights: • Overexpression of EVA1A suppresses GBM cell growth. • EVA1A induces autophagy through the mTOR/RPS6KB1 pathway. • EVA1A induces GBM cell apoptosis. • EVA1A inhibits the development of GBM in vivo.

    Human Factors Engineering (HFE) is a discipline whose goal is to engineer a safer, more efficient interface between humans and machines. HFE makes use of a wide range of tools and techniques to fulfill this goal. One of these tools is known as motion and time study, a technique used to develop time standards for given tasks. During the summer of 1995, a human factors motion and time study was initiated with the goals of developing a database of EVA task times and developing a method of utilizing the database to predict how long an EVA should take. Initial development relied on the EVA activities performed during the STS-61 (Hubble) mission. The first step of the study was to become familiar with EVA's, the previous task-time studies, and documents produced on EVA's. After reviewing these documents, an initial set of task primitives and task-time modifiers was developed. Data was collected from videotaped footage of two entire STS-61 EVA missions and portions of several others, each with two EVA astronauts. Feedback from the analysis of the data was used to further refine the primitives and modifiers used. The project was continued during the summer of 1996, during which data on human errors was also collected and analyzed. Additional data from the STS-71 mission was also collected. Analysis of variance techniques for categorical data was used to determine which factors may affect the primitive times and how much of an effect they have. Probability distributions for the various task were also generated. Further analysis of the modifiers and interactions is planned.

    The human hand has a wide range of degrees of freedom, allowing a great variety of movements, and is also one of the most sensitive parts of the human body. Due to these characteristics, it is the most important tool for astronauts to perform extravehicular activities (EVA). However, astronauts must wear mandatory EVA equipment to be protected from the harsh conditions in space and this strongly reduces hand performance, in particular as regards dexterity, tactile perception, mobility and fatigue. Several studies have been conducted to determine the influence of the EVA glove on manual capabilities, both in the past and more recently. This study presents experimental data regarding the performance decline occurring in terms of force and fatigue in the execution of grasping and pinching tasks when wearing an EVA glove, in pressurized and unpressurized conditions, compared with barehanded potential. Results show that wearing the unpressurized EVA glove hinders grip and lateral pinch performances, dropping exerted forces to about 50-70%, while it barely affects two- and three-finger pinch performances. On the other hand, wearing the pressurized glove worsens performances in all cases, reducing forces to about 10-30% of barehanded potential. The results are presented and compared with the previous literature.

    The authors investigated the in-situ processing temperatures and effects of various formulation additives on the formation of ultraviolet (UV) excitable chromophores, in the thermal lamination and curing of ethylene-vinyl acetate (EVA) encapsulants. A programmable, microprocessor-controlled, double-bag vacuum laminator was used to study two commercial as formulated EVA films, A9918P and 15295P, and solution-cast films of Elvaxrm (EVX) impregnated with various curing agents and antioxidants. The results show that the actual measured temperatures of EVA lagged significantly behind the programmed profiles for the heating elements and were affected by the total thermal mass loaded inside the laminator chamber. The antioxidant Naugard P{trademark}, used in the two commercial EVA formulations, greatly enhances the formation of UV-excitable, short chromophores upon curing, whereas other tested antioxidants show little effect. A new curing agent chosen specifically for the EVA formulation modification produces little or no effect on chromophore formation, no bubbling problems in the glass/EVX/glass laminates, and a gel content of {approximately}80% when cured at programmed 155{degrees}C for 4 min. Also demonstrated is the greater discoloring effect with higher concentrations of curing-generated chromophores.

    This paper describes the effort by the Texas Engineering Experiment Station (TEES) and Honeywell for NASA to design, fabricate, and test a preflight prototype pump for use in the Extravehicular activity (EVA) portable life support subsystem (PLSS). Major design decisions were driven by the need to reduce the pump s mass, power, and volume compared to the existing PLSS pump. In addition, the pump will accommodate a much wider range of abnormal conditions than the existing pump, including vapor/gas bubbles and increased pressure drop when employed to cool two suits simultaneously. A positive displacement, external gear type pump was selected because it offers the most compact and highest efficiency solution over the required range of flow rates and pressure drops. An additional benefit of selecting a gear pump design is that it is self priming and capable of ingesting noncondensable gas without becoming "air locked." The chosen pump design consists of a 28 V DC, brushless, sealless, permanent magnet motor driven, external gear pump that utilizes a Honeywell development that eliminates the need for magnetic coupling. Although the planned flight unit will use a sensorless motor with custom designed controller, the preflight prototype to be provided for this project incorporates Hall effect sensors, allowing an interface with a readily available commercial motor controller. This design approach reduced the cost of this project and gives NASA more flexibility in future PLSS laboratory testing. The pump design was based on existing Honeywell designs, but incorporated features specifically for the PLSS application, including all of the key features of the flight pump. Testing at TEES will simulate the vacuum environment in which the flight pump will operate. Testing will verify that the pump meets design requirements for range of flow rates, pressure rise, power consumption, working fluid temperature, operating time, and restart capability. Pump testing is currently

  11. Crosscutting Development- EVA Tools and Geology Sample Acquisition

    Science.gov (United States)

    2011-01-01

    Exploration to all destinations has at one time or another involved the acquisition and return of samples and context data. Gathered at the summit of the highest mountain, the floor of the deepest sea, or the ice of a polar surface, samples and their value (both scientific and symbolic) have been a mainstay of Earthly exploration. In manned spaceflight exploration, the gathering of samples and their contextual information has continued. With the extension of collecting activities to spaceflight destinations comes the need for geology tools and equipment uniquely designed for use by suited crew members in radically different environments from conventional field geology. Beginning with the first Apollo Lunar Surface Extravehicular Activity (EVA), EVA Geology Tools were successfully used to enable the exploration and scientific sample gathering objectives of the lunar crew members. These early designs were a step in the evolution of Field Geology equipment, and the evolution continues today. Contemporary efforts seek to build upon and extend the knowledge gained in not only the Apollo program but a wealth of terrestrial field geology methods and hardware that have continued to evolve since the last lunar surface EVA. This paper is presented with intentional focus on documenting the continuing evolution and growing body of knowledge for both engineering and science team members seeking to further the development of EVA Geology. Recent engineering development and field testing efforts of EVA Geology equipment for surface EVA applications are presented, including the 2010 Desert Research and Technology Studies (Desert RATs) field trial. An executive summary of findings will also be presented, detailing efforts recommended for exotic sample acquisition and pre-return curation development regardless of planetary or microgravity destination.

    Cyclones are widely used to separate particles from gas flows and as air emissions control devices. Their cost of operation is proportional to the fan energy required to overcome their pressure drop. Evasés or exit diffusers potentially could reduce exit pressure losses without affecting collection...

  17. Commercial Spacewalking: Designing an EVA Qualification Program for Space Tourism

    2010-01-01

    In the near future, accessibility to space will be opened to anyone with the means and the desire to experience the weightlessness of microgravity, and to look out upon both the curvature of the Earth and the blackness of space, from the protected, shirt-sleeved environment of a commercial spacecraft. Initial forays will be short-duration, suborbital flights, but the experience and expertise of half a century of spaceflight will soon produce commercial vehicles capable of achieving low Earth orbit. Even with the commercial space industry still in its infancy, and manned orbital flight a number of years away, there is little doubt that there will one day be a feasible and viable market for those courageous enough to venture outside the vehicle and into the void, wearing nothing but a spacesuit, armed with nothing but preflight training. What that Extravehicular Activity (EVA) preflight training entails, however, is something that has yet to be defined. A number of significant factors will influence the composition of a commercial EVA training program, but a fundamental question remains: 'what minimum training guidelines must be met to ensure a safe and successful commercial spacewalk?' Utilizing the experience gained through the development of NASA's Skills program - designed to qualify NASA and International Partner astronauts for EVA aboard the International Space Station - this paper identifies the attributes and training objectives essential to the safe conduct of an EVA, and attempts to conceptually design a comprehensive training methodology meant to represent an acceptable qualification standard.

    Training for a spacewalk or extravehicular activity (EVA) is considered a hazardous duty for NASA astronauts. This places astronauts at risk for decompression sickness as well as various musculoskeletal disorders from working in the spacesuit. As a result, the operational and research communities over the years have requested access to EVA training data to supplement their studies. The purpose of this paper is to document the comprehensive EVA training data set that was compiled from multiple sources by the Lifetime Surveillance of Astronaut Health (LSAH) epidemiologists to investigate musculoskeletal injuries. The EVA training dataset does not contain any medical data, rather it only documents when EVA training was performed, by whom and other details about the session. The first activities practicing EVA maneuvers in water were performed at the Neutral Buoyancy Simulator (NBS) at the Marshall Spaceflight Center in Huntsville, Alabama. This facility opened in 1967 and was used for EVA training until the early Space Shuttle program days. Although several photographs show astronauts performing EVA training in the NBS, records detailing who performed the training and the frequency of training are unavailable. Paper training records were stored within the NBS after it was designated as a National Historic Landmark in 1985 and closed in 1997, but significant resources would be needed to identify and secure these records, and at this time LSAH has not pursued acquisition of these early training records. Training in the NBS decreased when the Johnson Space Center in Houston, Texas, opened the Weightless Environment Training Facility (WETF) in 1980. Early training records from the WETF consist of 11 hand-written dive logbooks compiled by individual workers that were digitized at the request of LSAH. The WETF was integral in the training for Space Shuttle EVAs until its closure in 1998. The Neutral Buoyancy Laboratory (NBL) at the Sonny Carter Training Facility near JSC

    Human hands play a significant role during Extravehicular Activity (EVA) missions and Neutral Buoyancy Lab (NBL) training events, as they are needed for translating and performing tasks in the weightless environment. Because of this high frequency usage, hand and arm related injuries are known to occur during EVA and EVA training in the NBL. The primary objectives of this investigation were to: 1) document all known EVA glove related injuries and circumstances of these incidents, 2) determine likely risk factors, and 3) recommend interventions where possible that could be implemented in the current and future glove designs. METHODS: The investigation focused on the discomforts and injuries of U.S. crewmembers who had worn the pressurized Extravehicular Mobility Unit (EMU) spacesuit and experienced 4000 Series or Phase VI glove related incidents during 1981 to 2010 for either EVA ground training or in-orbit flight. We conducted an observational retrospective case-control investigation using 1) a literature review of known injuries, 2) data mining of crew injury, glove sizing, and hand anthropometry databases, 3) descriptive statistical analyses, and finally 4) statistical risk correlation and predictor analyses to better understand injury prevalence and potential causation. Specific predictor statistical analyses included use of principal component analyses (PCA), multiple logistic regression, and survival analyses (Cox proportional hazards regression). Results of these analyses were computed risk variables in the forms of odds ratios (likelihood of an injury occurring given the magnitude of a risk variable) and hazard ratios (likelihood of time to injury occurrence). Due to the exploratory nature of this investigation, we selected predictor variables significant at p=0.15. RESULTS: Through 2010, there have been a total of 330 NASA crewmembers, from which 96 crewmembers performed 322 EVAs during 1981-2010, resulting in 50 crewmembers being injured inflight and 44

    Full Text Available The adjustment of material composition in fabrication of modified polymeric membrane has been considered the most efficient and easiest method. For this purpose blended membranes of high density polyethylene (HDPE–ethylene vinyl acetate (EVA were prepared by thermally induced phase separation method. The impact of EVA in the presence of diluent on the crystalization temperature was assessed using differential scanning calorimetry (DSC. The obtained results showed that EVA has no significant effect on the crystalization temperature of HDPE. The absorption frequencies at 1248 and 1749 cm-1, respectively, due to C-O and C=O streching vibrations of EVA functional groups, confirmed the existence of EVA in HDPE membrane. The pure water permeability of HDPE/EVA blend was measured and compared with that of neat HDPE membrane. The results showed that an EVA content up to 2.5 wt% raised water permeability considerably and the leafy structure of the membranes contracted and the pure water permeation dropped with higher EVA content. The results of porosity measurement and scanning electronic microscopic (SEM analysis also confirmed these findings. Contact angel measurements and atomic force microscopy (AFM examinations and static absorption of collagen protein on the membrane surfaces revealed that EVA content up to 5 wt% lowered the hydrophobicity of the membrane. By EVA content above 10 wt%, due to the structural alteration on the membrane surface, the contact angel and the collagen absorption on the surface of membrane increased. The measurement of tensile strength showed that with increasing EVA content the mechanical properties of the membranes improved due to interactions of polar groups in EVA.

    To avoid the systemic adverse effects that might occur after oral administration, transdermal delivery of ambroxol was studied as a method for maintaining proper blood levels for an extended period. Release of ambroxol according to concentration and temperature was determined, and permeation of drug through rat skin was studied using two chamber-diffusion cells. The solubility according to PEG 400 volume fraction was highest at 40% PEG 400. The rate of drug release from the EVA matrix increased with increased temperature and drug loading doses. A linear relationship existed between the release rate and the square root of loading rate. The activation energy (Ea) was measured from the slope of the plot of log P versus 1000/T and was found to be 10.71, 10.39, 10.33 and 9.87 kcal/mol for 2, 3, 4 and 5% loading dose from the EVA matrix, respectively. To increase the permeation rate of ambroxol across rat skin from the EVA matrix, various penetration enhancers such as fatty acids (saturated, unsaturated), propylene glycols, glycerides, pyrrolidones, and non-ionic surfactants were used. The enhancing effects of the incorporated enhancers on the skin permeation of ambroxol were evaluated using Franz diffusion cells fitted with intact excised rat skin at 37° using 40% PEG 400 solution as a receptor medium. Among the enhancers used, polyoxyethylene-2-oleyl ether increased the permeation rate by 4.25-fold. In conclusion, EVA matrix containing plasticizer and permeation enhancer could be developed for enhanced transdermal delivery of ambroxol. PMID:23325993

  15. Non-Venting Thermal and Humidity Control for EVA Suits

    Izenson, Mike; Chen, Weibo; Bue, Grant

    2011-01-01

    Future EVA suits need processes and systems to control internal temperature and humidity without venting water to the environment. This paper describes an absorption-based cooling and dehumidification system as well as laboratory demonstrations of the key processes. There are two main components in the system: an evaporation cooling and dehumidification garment (ECDG) that removes both sensible heat and latent heat from the pressure garment, and an absorber radiator that absorbs moisture and rejects heat to space by thermal radiation. This paper discusses the overall design of both components, and presents recent data demonstrating their operation. We developed a design and fabrication approach to produce prototypical heat/water absorbing elements for the ECDG, and demonstrated by test that these elements could absorb heat and moisture at a high flux. Proof-of-concept tests showed that an ECDG prototype absorbs heat and moisture at a rate of 85 W/ft under conditions that simulate operation in an EVA suit. The heat absorption was primarily due to direct absorption of water vapor. It is possible to construct large, flexible, durable cooling patches that can be incorporated into a cooling garment with this system. The proof-of-concept test data was scaled to calculate area needed for full metabolic loads, thus showing that it is feasible to use this technology in an EVA suit. Full-scale, lightweight absorber/radiator modules have also been built and tested. They can reject heat at a flux of 33 W/ft while maintaining ECDG operation at conditions that will provide a cool and dry environment inside the EVA suit.

    2015-01-01

    The objectives of the High Performance EVA Glove task are to develop advanced EVA gloves for future human space exploration missions and generate corresponding standards by which progress may be quantitatively assessed. New technologies and manufacturing techniques will be incorporated into the new gloves to address finger and hand mobility, injury reduction and durability in nonpristine environments. Three prototypes will be developed, each focusing on different technological advances. A robotic assist glove will integrate a powered grasping system into the current EVA glove design to reduce astronaut hand fatigue and hand injuries. A mechanical counter pressure (MCP) glove will be developed to further explore the potential of MCP technology and assess its capability for countering the effects of vacuum or low pressure environments on the body by using compression fabrics or materials to apply the necessary pressure. A gas pressurized glove, incorporating new technologies, will be the most flight-like of the three prototypes. Advancements include the development and integration of aerogel insulation, damage sensing components, dust-repellant coatings, and dust tolerant bearings.

    The transition from low earth orbit Extravehicular Activity (EVA) for construction and maintenance activities to planetary surface EVA on asteroids, moons, and, ultimately, Mars demands a new spacesuit system. NASA's development of that system has resulted in dramatically different pumping requirements from those in the current spacesuit system. Hamilton Sundstrand, Cascon, and NASA are collaborating to develop and mature a pump that will reliably meet those new requirements in space environments and within the design constraints imposed by spacesuit system integration. That collaboration, which began in the NASA purchase of a pump prototype for test evaluation, is now entering a new phase of development. A second generation pump reflecting the lessons learned in NASA's testing of the original prototype will be developed under Hamilton Sundstrand internal research funding and ultimately tested in an integrated Advanced Portable Life Support System (APLSS) in NASA laboratories at the Johnson Space Center. This partnership is providing benefit to both industry and NASA by supplying a custom component for EVA integrated testing at no cost to the government while providing test data for industry that would otherwise be difficult or impossible to duplicate in industry laboratories. This paper discusses the evolving collaborative process, component requirements and design development based on early NASA test experience, component stand alone test results, and near term plans for integrated testing at JSCs.

    The EVA (Endoscopic Video Analysis) tracking system is a new system for extracting motions of laparoscopic instruments based on nonobtrusive video tracking. The feasibility of using EVA in laparoscopic settings has been tested in a box trainer setup. EVA makes use of an algorithm that employs information of the laparoscopic instrument's shaft edges in the image, the instrument's insertion point, and the camera's optical center to track the three-dimensional position of the instrument tip. A validation study of EVA comprised a comparison of the measurements achieved with EVA and the TrEndo tracking system. To this end, 42 participants (16 novices, 22 residents, and 4 experts) were asked to perform a peg transfer task in a box trainer. Ten motion-based metrics were used to assess their performance. Construct validation of the EVA has been obtained for seven motion-based metrics. Concurrent validation revealed that there is a strong correlation between the results obtained by EVA and the TrEndo for metrics, such as path length (ρ = 0.97), average speed (ρ = 0.94), or economy of volume (ρ = 0.85), proving the viability of EVA. EVA has been successfully validated in a box trainer setup, showing the potential of endoscopic video analysis to assess laparoscopic psychomotor skills. The results encourage further implementation of video tracking in training setups and image-guided surgery.

    Full Text Available The incorporation of micrometer sized silica particles on poly (ethylene-co-vinyl acetate - EVA - residues from the footwear industry was evaluated. The effects of the processing parameters - temperature and mixing ratio - on the mechanical behavior of molded plates of neat recycled EVA and EVA/silica composites were also investigated. The mechanical properties measured by the tensile test, the fractographic analysis by scanning electron microscopy (SEM, and the 13C Nuclear Magnetic Resonance (NMR showed a reduced EVA to silica compatibility. Therefore, incorporation of untreated silica to recycled EVA copolymer produced a slight decrease on the mechanical performance of EVA/silica composites in respect to neat EVA copolymer. The NMR analysis also shows that the crosslinking process on recycled EVA may be occurring at the carbonyl group.

    EVA1A is an autophagy-related protein, which plays an important role in embryonic neurogenesis. In this study, we found that loss of EVA1A could decrease neural differentiation in the brain of adult Eva1a-/- mice. To determine the mechanism underlying this phenotype, we performed label-free quantitative proteomics and bioinformatics analysis using the brains of Eva1a-/- and wild-type mice. We identified 11 proteins that were up-regulated and 17 that were down-regulated in the brains of the knockout mice compared to the wild-type counterparts. Bioinformatics analysis indicated that biological processes, including ATP synthesis, oxidative phosphorylation, and the TCA cycle, are involved in the EVA1A regulatory network. In addition, gene set enrichment analysis showed that neurodegenerative diseases, such as Alzheimer's disease and Huntington's disease, were strongly associated with Eva1a knockout. Western blot experiments showed changes in the expression of nicotinamide nucleotide transhydrogenase, an important mitochondrial enzyme involved in the TCA cycle, in the brains of Eva1a knockout mice. Our study provides valuable information on the molecular functions and regulatory network of the Eva1a gene, as well as new perspectives on the relationship between autography-related proteins and neural differentiation. © 2017 Proteomics Published by Wiley-VCH Verlag GmbH & Co.

    Ongoing assembly and maintenance activities at the International Space Station (ISS) require much more extravehicular activity (EVA) than did the earlier U.S. Space Shuttle missions. It is thus desirable to determine and analyze, and possibly foresee, as accurately as possible what radiation exposures crew members involved in EVAs will experience in order to minimize risks and to establish exposure limits that must not to be exceeded. A detailed CAD model of the U.S. Space Shuttle EVA Spacesuit, developed at NASA Langley Research Center (LaRC), is used to represent the directional shielding of an astronaut; it has detailed helmet and backpack structures, hard upper torso, and multilayer space suit fabric material. The NASA Computerized Anatomical Male and Female (CAM and CAF) models are used in conjunction with the space suit CAD model for dose evaluation within the human body. The particle environments are taken from the orbit-averaged NASA AP8 and AE8 models at solar cycle maxima and minima. The transport of energetic particles through space suit materials and body tissue is calculated by using the NASA LaRC HZETRN code for hadrons and a recently developed deterministic transport code, ELTRN, for electrons. The doses within the CAM and CAF models are determined from energy deposition at given target points along 968 directional rays convergent on the points and are evaluated for several points on the skin and within the body. Dosimetric quantities include contributions from primary protons, light ions, and electrons, as well as from secondary brehmsstrahlung and target fragments. Directional dose patterns are displayed as rays and on spherical surfaces by the use of a color relative intensity representation.

  5. Techniques for Improving the Performance of Future EVA Maneuvering Systems

    Williams, Trevor W.

    1995-01-01

    The Simplified Aid for EVA Rescue (SAFER) is a small propulsive backpack that was developed as an in-house effort at Johnson Space Center; it is a lightweight system which attaches to the underside of the Primary Life Support Subsystem (PLSS) backpack of the Extravehicular Mobility Unit (EMU). SAFER provides full six-axis control, as well as Automatic Attitude Hold (AAH), by means of a set of cold-gas nitrogen thrusters and a rate sensor-based control system. For compactness, a single hand controller is used, together with mode switching, to command all six axes. SAFER was successfully test-flown on the STS-64 mission in September 1994 as a Development Test Objective (DTO); development of an operational version is now proceeding. This version will be available for EVA self-rescue on the International Space Station and Mir, starting with the STS-86/Mir-7 mission in September 1997. The DTO SAFER was heavily instrumented, and produced in-flight data that was stored in a 12 MB computer memory on-board. This has allowed post-flight analysis to yield good estimates for the actual mass properties (moments and products of inertia and center of mass location) encountered on-orbit. By contrast, Manned Maneuvering Unit (MMU) post-flight results were generated mainly from analysis of video images, and so were not very accurate. The main goal of the research reported here was to use the detailed SAFER on-orbit mass properties data to optimize the design of future EVA maneuvering systems, with the aim being to improve flying qualities and/or reduce propellant consumption. The Automation, Robotics and Simulation Division Virtual Reality (VR) Laboratory proved to be a valuable research tool for such studies. A second objective of the grant was to generate an accurate dynamics model in support of the reflight of the DTO SAFER on STS-76/Mir-3. One complicating factor was the fact that a hand controller stowage box was added to the underside of SAFER on this flight; the position of

    In this study, on the basis of complex Eu(DBM)3Phen which was widely applied in polymer matrices, quaternary complex Eu(DBM)2Phen(TA) was synthesized by the introduction of 1-tridecanecarboxylic acid (TA). XRD analyses show that Eu(DBM)2Phen(TA) inclines to amorphization compared with Eu(DBM)3Phen which is crystal. Ethylene-vinyl acetate (EVA) film doped with Eu(DBM)2Phen(TA) was prepared by casting method. SEM and AFM analyses show that the compatibility of Eu(DBM)2Phen(TA) with EVA is better than that of Eu(DBM)3Phen with EVA. Under the same addition amount of Eu3+ complexes, visible light transmittance of Eu(DBM)2Phen(TA)/EVA film is obviously greater than that of Eu(DBM)3Phen/EVA film, and the fluorescence intensity of Eu(DBM)2Phen(TA)/EVA film is only slightly lower than that of Eu(DBM)3Phen/EVA film. With the optimum addition amount of Eu3+ complexes, the energy conversion efficiency of the polycrystalline silicon solar cell coated with Eu(DBM)2Phen(TA)/EVA film is improved to 12.14%, and in comparison, that of the solar cell coated with Eu(DBM)3Phen/EVA film is only 11.98%. Hence Eu(DBM)2Phen(TA)/EVA film has a potential prospect as luminescent down-shifting material.

    The effects of ethylene-vinyl acetate (EVA) discoloration due to accelerated field or laboratory exposure on the encapsulated silicon (Si) solar cells or EVA/glass laminates were characterized quantitatively by using non-invasive, non-destructive ultraviolet-visible (UV-vis) spectrophotometry, spectrocolorimetry, spectrofluorometry, scanning laser OBIC (optical beam induced current) spectroscopy, and current-voltage (I-V) and quantum efficiency (QE) measurements. The results show that the yellowness index (YI) measured directly over the AR-coated solar cells under the glass superstrate increased from the range of -80 to -90 to the range of -20 to 15 as the EVA changed from clear to brown. The ratio of two fluorescence emission peak areas generally increased from 1.45 to 5.69 as browning increased, but dropped to 4.21 on a darker EVA. For a solar cell with brown EVA in the central region, small-area grating QE measurements and scanning laser OBIC analysis between the brown and clear EVA regions showed that the quantum efficiency loss at 633 nm was 42%-48% of the loss at 488 nm, due to a reduced decrease of transmittance in browned EVA at the longer wavelengths. The portion of the solar cell under the browned EVA showed a decrease of {approximately}36% in efficiency, as compared to the cell efficiency under clear EVA. Transmittance loss at 633 nm was 38% of the loss at 488 nm for a light yellow-brown EVA/glass laminate that showed a small increase of 10 in the yellowness index.

    Full Text Available Modified atmosphere is a method of food preservation that provides increased lifetime, decreases deterioration losses, and facilitates marketing. The objective of this study was to evaluate the efficiency of different plastic films in modifying the atmosphere around Eva apples to assure quality maintenance during postharvest storage. The fruits were cleaned and separated into three treatment groups: polypropylene, low density polyethylene, and high density polyethylene packing with a total of 5 fruits per package for each evaluation period. A group of control apples was not submitted to atmospheric modification. After the treatment, all fruits were stored at 0.5±0.5°C (cold storage for up to 225 days. The analyses were performed at 45, 135, and 225 days after cold storage. Respiration, ethylene production, firmness, mass loss, total pectin, soluble pectin, soluble solids, total acidity, and epidermis background color of each treatment group were evaluated. The high density polyethylene film treatment did not show a decrease in ethylene production during storage and allowed the fruits to maintain a greater firmness and smaller percentage of mass loss during the study period. Moreover, the storage of the Eva apple cultivar under modified atmosphere allowed the preservation of quality for up to seven months.

    Organo-modified Cloisite clays at varying contents were incorporated into poly(ethylene-co-vinyl acetate) (EVA) by melt blending. Nanoclay dispersion in films was first evaluated. The water transport properties were investigated by pervaporation and sorption measurements. A decrease of the water permeation flux was obtained when incorporating nanoparticles. This barrier effect is usually attributed to the increase of the diffusion pathways due to nanoclay-induced tortuosity effects. However, the diffusion coefficient was found to be dependent on water concentration, which generally reflects a plasticization effect of water. Besides, at 7 wt% of loading, an unexpected increase of water diffusivity was measured with a time-scale shift of the permeation flux. This was correlated with the formation of preferential diffusion pathways along interfacial regions due to free volumes existing between the EVA matrix and nanoclays as well as the water affinity of microfillers. As a consequence, water mass gain was found to be increased. The water-induced plasticization of sorbed water molecules was also highlighted through sorption kinetics. Eventually, some applications to these films in which water barrier behaviour is required were discussed.

    Human hands play a significant role during extravehicular activity (EVA) missions and Neutral Buoyancy Lab (NBL) training events, as they are needed for translating and performing tasks in the weightless environment. It is because of this high frequency usage that hand- and arm-related injuries and discomfort are known to occur during training in the NBL and while conducting EVAs. Hand-related injuries and discomforts have been occurring to crewmembers since the days of Apollo. While there have been numerous engineering changes to the glove design, hand-related issues still persist. The primary objectives of this study are therefore to: 1) document all known EVA glove-related injuries and the circumstances of these incidents, 2) determine likely risk factors, and 3) recommend ergonomic mitigations or design strategies that can be implemented in the current and future glove designs. METHODS: The investigator team conducted an initial set of literature reviews, data mining of Lifetime Surveillance of Astronaut Health (LSAH) databases, and data distribution analyses to understand the ergonomic issues related to glove-related injuries and discomforts. The investigation focused on the injuries and discomforts of U.S. crewmembers who had worn pressurized suits and experienced glove-related incidents during the 1980 to 2010 time frame, either during training or on-orbit EVA. In addition to data mining of the LSAH database, the other objective of the study was to find complimentary sources of information such as training experience, EVA experience, suit-related sizing data, and hand-arm anthropometric data to be tied to the injury data from LSAH. RESULTS: Past studies indicated that the hand was the most frequently injured part of the body during both EVA and NBL training. This study effort thus focused primarily on crew training data in the NBL between 2002 and 2010. Of the 87 recorded training incidents, 19 occurred to women and 68 to men. While crew ages ranged from

    2014-01-01

    The Asteroid Redirect Crewed Mission (ARCM) requires a Launch/Entry/Abort (LEA) suit capability and short duration Extra Vehicular Activity (EVA) capability for Orion. The EVAs will involve a two-person crew for approximately four hours. Currently, two EVAs are planned with one contingency EVA in reserve. Providing this EVA capability is very challenging due to system level constraints and a new and unknown environment. The goal of the EVA architecture for ARCM is one that builds upon previously developed technologies and lessons learned, and that accomplishes the ARCM mission while providing a stepping stone to future missions and destinations. The primary system level constraints are to 1) minimize system mass and volume and 2) minimize the interfacing impacts to the baseline Orion design. In order to minimize the interfacing impacts and to not perturb the baseline Orion schedule, the concept of adding "kits" to the baseline system is proposed. These kits consist of: an EVA kit (converts LEA suit to EVA suit), EVA Servicing and Recharge Kit (provides suit consumables), the EVA Tools, Translation Aids & Sample Container Kit (the tools and mobility aids to complete the tasks), the EVA Communications Kit (interface between the EVA radio and the MPCV), and the Cabin Repress Kit (represses the MPCV between EVAs). This paper will focus on the trade space, analysis, and testing regarding the space suit (pressure garment and life support system). Historical approaches and lessons learned from all past EVA operations were researched. Previous and current, successfully operated EVA hardware and high technology readiness level (TRL) hardware were evaluated, and a trade study was conducted for all possible pressure garment and life support options. Testing and analysis was conducted and a recommended EVA system architecture was proposed. Pressure garment options that were considered for this mission include the currently in-use ISS EVA Mobility Unit (EMU), all variations of

    The primary objective of this study is to develop a protocol to reliably characterize human health and performance metrics for individuals working inside various EVA suits under realistic spaceflight conditions. Expected results and methodologies developed during this study will provide the baseline benchmarking data and protocols with which future EVA suits and suit configurations (e.g., varied pressure, mass, center of gravity [CG]) and different test subject populations (e.g., deconditioned crewmembers) may be reliably assessed and compared. Results may also be used, in conjunction with subsequent testing, to inform fitness-for-duty standards, as well as design requirements and operations concepts for future EVA suits and other exploration systems.

    When we send humans to search for life on other planets, we'll need to know what we brought with us versus what may already be there. To ensure our crewed systems meet planetary protection requirements-and to protect our science from human contamination-we'll need to assess whether microorganisms may be leaking or venting from our spacecraft. Microbial sample collection outside of a pressurized spacecraft is complicated by temperature extremes, low pressures that preclude the use of laboratory standard (wetted) swabs, and operation either in bulky spacesuits or with robotic assistance. Engineers at the National Aeronautics and Space Administration (NASA) recently developed a swab kit for use in collecting microbial samples from the external surfaces of crewed spacecraft, including spacesuits. The Extravehicular Activity (EVA) Swab Kit consists of a single swab tool handle and an eight-canister sample caddy. The design team minimized development cost by re-purposing a heritage Space Shuttle tile repair handle that was designed to quickly snap into different tool attachments by engaging a mating device in each attachment. This allowed the tool handle to snap onto a fresh swab attachment much like popular shaving razor handles can snap onto a disposable blade cartridge. To disengage the handle from a swab, the user performs two independent functions, which can be done with a single hand. This dual operation mitigates the risk that a swab will be inadvertently released and lost in microgravity. Each swab attachment is fitted with commercially available foam swab tips, vendor-certified to be sterile for Deoxyribonucleic Acid (DNA). A microbial filter installed in the bottom of each sample container allows the container to outgas and repressurize without introducing microbial contaminants to internal void spaces. Extensive ground testing, post-test handling, and sample analysis confirmed the design is able to maintain sterile conditions as the canister moves between

    1992-01-01

    An advanced electronic system for future EVA missions (including zero gravity, the lunar surface, and the surface of Mars) is under research and development within the Advanced Life Support Division at NASA Ames Research Center. As a first step in the development, an optimum system architecture has been derived from an analysis of the projected requirements for these missions. The open, modular architecture centers around a distributed multiprocessing concept where the major subsystems independently process their own I/O functions and communicate over a common bus. Supervision and coordination of the subsystems is handled by an embedded real-time operating system kernel employing multitasking software techniques. A discussion of how the architecture most efficiently meets the electronic system functional requirements, maximizes flexibility for future development and mission applications, and enhances the reliability and serviceability of the system in these remote, hostile environments is included.

    The procedure and results of the performance evaluation of the EVA Metro Sedan (car No. 1) variable speed dc chopper motor drive and its three speed automatic transmission are presented. The propulsion system for a battery powered vehicle manufactured by Electric Vehicle Associates, Valley View, Ohio, was removed from the vehicle, mounted on the programmable electric dynamometer test facility and evaluated with the aid of a hp 3052A Data Acquisition System. Performance data for the automatic transmission, the solid state dc motor speed controller, and the dc motor in the continuous and pulsating dc power mode, as derived on the dynamometer test facility, as well as the entire propulsion system are given. This concept and the system's components were evaluated in terms of commercial applicability, maintainability, and energy utility to establish a design base for the further development of this system or similar propulsion drives. The propulsion system of the EVA Metro Sedan is powered by sixteen 6-volt traction batteries, Type EV 106 (Exide Battery Mfg. Co.). A thyristor controlled cable form Pulsomatic Mark 10 controller, actuated by a foot throttle, controls the voltage applied to a dc series field motor, rated at 10 hp at 3800 rpm (Baldor Electric Co.). Gear speed reduction to the wheel is accomplished by the original equipment three speed automatic transmission with torque converter (Renault 12 Sedan). The brake consists of a power-assisted, hydraulic braking system with front wheel disk and rear drum. An ability to recuperate electric energy with subsequent storage in the battery power supply is not provided.

    2015-09-01

    Full Text Available This paper investigates the influence of the economic value added (EVA performance evaluation, issued in 2010 by the State-owned Assets Supervision and Administration Commission of the State Council, on the value of the cash holdings of central state-owned enterprises (CSOEs. We find that EVA performance evaluation has some influence on the overinvestment of CSOE cash holdings and significantly increases the value of CSOE cash holdings compared with the cash holdings of local state-owned enterprises. The greater value of CSOE cash holdings derives from underinvestment modification and overinvestment restraint. The value of cash holdings increases more for companies with better accounting performance. Thus, the EVA performance evaluation policy increases CSOE efficiency. This study contributes to the emerging literature related to cash holdings and the economic consequences of the EVA performance evaluation policy. It expands the literature related to investor protection in countries experiencing economic transition.

    Full Text Available Samples of Ethylene-Vinyl Acetate (EVA were doped with particles of Boron Nitride (BN in concentrations ranging from 0-60% w/w. Thermal conductivity was measured using a Differential Scanning Calorimetery (DSC technique. The thermal conductivity of parent EVA was increased from 0.24W/m ⋅ K to 0.80W/m ⋅ K for the 60% w/w sample. Two PV laminates were made; one using the parent EVA the other using EVA doped with 50% BN. When exposed to a one directional heat flux the doped laminate was, on average, 6% cooler than the standard laminate. A finite difference model had good agreement with experimental results and showed that the use of 60% BN composite achieved a PV performance increase of 0.3% compared to the standard laminate.

    Full Text Available The Economic Value Added (EVA is an index of “durable development.” It was proposed by the Stern-Stewart Office and represents the true economic profit of companies. A company reports economic profit only if thereported accounting profit is higher than the opportunity cost of equity. The authors of the EVA model (Stern-Stewart have also proposed the ways of restating the financial statements to get a “fair image” of the results, thuseliminating the “accounting distortions.”Based on the performance indexes calculated based on EVA and second-generation indexes relating toEVA, we calculated two types of rating: Rating Performance Current and Rating Performance Trend. The rating iscalculated by means of the percentiles technique and the results are split into 22 rating classes.The used database is Russell 3000.

    Injuries to the hands are common among astronauts who train for extravehicular activity (EVA). Many of these injuries refer to the gloves worn during EVA as the root cause. While pressurized, the bladder and outer material of these gloves restrict movement and create pressure points while performing tasks, sometimes resulting in pain, muscle fatigue, abrasions, and occasionally a more severe injury, onycholysis (fingernail delamination). The most common injury causes are glove contact (pressure point/rubbing), ill-fitting gloves, and/or performing EVA tasks in pressurized gloves. A brief review of the Lifetime Surveillance of Astronaut Health's injury database reveals over 57% of the total injuries to the upper extremities during EVA training occurred either to the metacarpophalangeal (MCP) joint, fingernail, or the fingertip. Twenty-five of these injuries resulted in a diagnosis of onycholysis.

  19. Mechanical behavior of recycled lightweight concrete using EVA waste and CDW under moderate temperature

    Directory of Open Access Journals (Sweden)

    E. Q. R. Santiago

    Full Text Available Many benefits can be achieved by using recycled waste as raw material for construction. Some of them are the reduction of the total cost of the construction, the reduction of the consumption of energy and the decrease in the use of natural materials. The construction sector can also incorporate the waste of the other industries, like the waste of the shoes industry, the Ethylene Vinyl Acetate (EVA. EVA aggregate is obtained by cutting off the waste of EVA expanded sheets used to produce insoles and innersoles of the shoes. In this work two types of recycled aggregate were used - construction and demolition waste (CDW and EVA. The aim of this work was to study the influence of the use of these recycled aggregates, as replacement of the natural coarse aggregate, on mechanical behavior of recycled concrete. The experimental program was developed with two w/c ratio: 0.49 and 0.82. Four mixtures with produced with different aggregates substitution rates (0, 50%EVA, 50%CDW and 25%EVA-25%CDW, by volume. Compressive tests were carried out to evaluable the influence of recycled aggregate on strength, elastic modulus and Poisson coefficient. In addition, it was evaluated the effect of the moderate temperatures (50, 70 and 100º C on stress-strain behavior of concretes studied. The results demonstrated that is possible to use the EVA waste and RCD to produces lightweight concrete. The influence of temperature was more significant only on elastic modulus of the recycled concrete with 50%EVA.

    Self-renewal and differentiation of neural stem cells is essential for embryonic neurogenesis, which is associated with cell autophagy. However, the mechanism by which autophagy regulates neurogenesis remains undefined. Here, we show that Eva1a/Tmem166, an autophagy-related gene, regulates neural stem cell self-renewal and differentiation. Eva1a depletion impaired the generation of newborn neurons, both in vivo and in vitro. Conversely, overexpression of EVA1A enhanced newborn neuron generation and maturation. Moreover, Eva1a depletion activated the PIK3CA-AKT axis, leading to the activation of the mammalian target of rapamycin and the subsequent inhibition of autophagy. Furthermore, addition of methylpyruvate to the culture during neural stem cell differentiation rescued the defective embryonic neurogenesis induced by Eva1a depletion, suggesting that energy availability is a significant factor in embryonic neurogenesis. Collectively, these data demonstrated that EVA1A regulates embryonic neurogenesis by modulating autophagy. Our results have potential implications for understanding the pathogenesis of neurodevelopmental disorders caused by autophagy dysregulation. Copyright © 2016 The Authors. Published by Elsevier Inc.

    Full Text Available This paper aims to contribute to acoustical comfort in buildings by presenting a study about the polymer waste micronized poly (ethylene vinyl acetate (EVA to be used in mortars for impact sound insulation in subfloor systems. The evaluation method included physical, mechanical and morphological properties of the mortar developed with three distinct thicknesses designs (3, 5, and 7 cm with replacement percentage of the natural aggregate by 10%, 25%, and 50% EVA. Microscopy analysis showed the surface deposition of cement on EVA, with preservation of polymer porosity. The compressive creep test estimated long-term deformation, where the 10% EVA sample with a 7 cm thick mortar showed the lowest percentage deformation of its height. The impact noise test was performed with 50% EVA samples, reaching an impact sound insulation of 23 dB when the uncovered slab was compared with the 7 cm thick subfloor mortar. Polymer waste addition decreased the mortar compressive strength, and EVA displayed characteristics of an influential material to intensify other features of the composite.

    The 2007 Energy Independence and Security Act (Public Law 110-140) directs the U.S. Geological Survey (USGS) to conduct a national assessment of potential geologic storage resources for carbon dioxide (CO2). The methodology used for the national CO2 assessment is non-economic and intended to be used at regional to subbasinal scales. This report identifies and contains geologic descriptions of twelve storage assessment units (SAUs) in six separate packages of sedimentary rock within the Hanna, Laramie, and Shirley Basins of Wyoming. It focuses on the particular characteristics, specified in the methodology, that influence the potential CO2 storage resource in those SAUs. Specific descriptions of SAU boundaries as well as their sealing and reservoir units are included. Properties for each SAU, such as depth to top, gross thickness, net porous thickness, porosity, permeability, groundwater quality, and structural reservoir traps are provided to illustrate geologic factors critical to the assessment. Although assessment results are not contained in this report, the geologic information included herein will be employed, as specified in the methodology, to calculate a statistical Monte Carlo-based distribution of potential storage space in the various SAUs. Figures in this report show SAU boundaries and cell maps of well penetrations through the sealing unit into the top of the storage formation. Cell maps show the number of penetrating wells within one square mile and are derived from interpretations of incompletely attributed well data in a digital compilation that is known not to include all drilling. The USGS does not expect to know the location of all wells and cannot guarantee the amount of drilling through specific formations in any given cell shown on cell maps.

    Full Text Available Purpose of the article: This article is an illustrative case study describing usage of EVA indicator in chosen specific company. Key part of the article deals with application of EVA indicator in company. It consists of procedure how to adjust accounting data into required form and determine weight costs of capital. Then there is calculation of EVA indicator and other indicators based on it. Last part is comparison of results. Methodology/methods: The basic method is case study. Its aim is to demonstrate good understanding or causation explanation of particular example. It takes into account the overall context of the problem. Scientific aim: The objective of the article is to come near to theoretical economic procedures and highlight the problematic areas within the practical application of EVA indicator in the business. Next aim is to emphasize the importance of EVA indicator. Findings: This article illustrates some problematic issues that companies may face while calculating EVA indicator. Czech accounting standards do not correspond with international accounting standard methodology known as IFRS for compiling statements. First difficult area was conversion of assets into net operating assets NOA. Then operating profit is modified in respect of so-called unusual costs and revenues. The next issue in calculation of EVA indicator is stating average weight costs on capital. The last area of problems is the time flow of leasing contracts, value of liabilities arising from them and assessing the lifetime of leased property. Conclusions: The article empirically examined the effectiveness of EVA indicator with regard to its relation to the accounting performance indicators. It was proved that although the company reported financial health within the frame of financial analysis, it gave owners only slightly increasing economic value added. The article points out the need of usege of EVA indicator in corporate practice.

    Full Text Available This research investigated the simultaneous impact and partial impact of financial ratios (ROA, ROE, EPS and Economic Value-Added (EVA on stock return. One of the four independent variables, that is EVA, are new concepts for measuring financial performance. Explanatory method was used in this research, and the sample was collected using purposive sampling method from Jakarta Islamic Index listed in Bursa Efek Indonesia (BEI, Indonesia Stock Exchange for the period 2005 - 2007. Multiple linear regression was used for the analysis in this research.The result of the analysis shows that all independent variables, that is Return on Assets (ROA, Return on Equity (ROE, Earnings per Share (EPS and EVA have both simultaneous and partial impact on the dependent variable, that is stock return. An interesting finding is that the regression coefficients are different among the variables. ROE and EPS were found to have positive and significant impact on dependent variable while EVA and ROA were found to have negative and significant impact on dependent variable. A positive value for ROE means that the ROE variable can be taken as a measure for a company’s effectivity in utilizing equity in the effort to gain profit. While EPS was found to have the most dominant impact on stock price. The higher the EPS, the greater management’s success in gaining profit for the shareholder or investors. ROA was found to have negative and significant. A finding of this research which is contrary to previous research is that economic value added (EVA was found to have negative and significant impact on stock price. However this finding can be explained as follows: first, the average debt in the companies in the sample is greater than the value of their equity so that EVA will increase due to the reduction in WACC. The increase in EVA is accompanied by a reduction in stock return. Second, positive EVA is not accompanied by any increase of stock performance in the market; and

    During lunar excursions in the EVA suit, real-time measurement of metabolic rate is required to manage consumables and guide activities to ensure safe return to the base. Metabolic rate, or oxygen consumption (VO2), is normally measured from pulmonary parameters but cannot be determined with standard techniques in the oxygen-rich environment of a spacesuit. Our group developed novel near infrared spectroscopic (NIRS) methods to calculate muscle oxygen saturation (SmO2), hematocrit, and pH, and we recently demonstrated that we can use our NIRS sensor to measure VO2 on the leg during cycling. Our NSBRI-funded project is looking to extend this methodology to examine activities which more appropriately represent EVA activities, such as walking and running and to better understand factors that determine the metabolic cost of exercise in both normal and lunar gravity. Our 4 year project specifically addresses risk: ExMC 4.18: Lack of adequate biomedical monitoring capability for Constellation EVA Suits and EPSP risk: Risk of compromised EVA performance and crew health due to inadequate EVA suit systems.

    2016-11-01

    Full Text Available Stratospheric sulfate aerosols from volcanic eruptions have a significant impact on the Earth's climate. To include the effects of volcanic eruptions in climate model simulations, the Easy Volcanic Aerosol (EVA forcing generator provides stratospheric aerosol optical properties as a function of time, latitude, height, and wavelength for a given input list of volcanic eruption attributes. EVA is based on a parameterized three-box model of stratospheric transport and simple scaling relationships used to derive mid-visible (550 nm aerosol optical depth and aerosol effective radius from stratospheric sulfate mass. Precalculated look-up tables computed from Mie theory are used to produce wavelength-dependent aerosol extinction, single scattering albedo, and scattering asymmetry factor values. The structural form of EVA and the tuning of its parameters are chosen to produce best agreement with the satellite-based reconstruction of stratospheric aerosol properties following the 1991 Pinatubo eruption, and with prior millennial-timescale forcing reconstructions, including the 1815 eruption of Tambora. EVA can be used to produce volcanic forcing for climate models which is based on recent observations and physical understanding but internally self-consistent over any timescale of choice. In addition, EVA is constructed so as to allow for easy modification of different aspects of aerosol properties, in order to be used in model experiments to help advance understanding of what aspects of the volcanic aerosol are important for the climate system.

  9. Conversion of IVA Human Computer Model to EVA Use and Evaluation and Comparison of the Result to Existing EVA Models

    This paper describes the methods, rationale, and comparative results of the conversion of an intravehicular (IVA) 3D human computer model (HCM) to extravehicular (EVA) use and compares the converted model to an existing model on another computer platform. The task of accurately modeling a spacesuited human figure in software is daunting: the suit restricts the human's joint range of motion (ROM) and does not have joints collocated with human joints. The modeling of the variety of materials needed to construct a space suit (e. g. metal bearings, rigid fiberglass torso, flexible cloth limbs and rubber coated gloves) attached to a human figure is currently out of reach of desktop computer hardware and software. Therefore a simplified approach was taken. The HCM's body parts were enlarged and the joint ROM was restricted to match the existing spacesuit model. This basic approach could be used to model other restrictive environments in industry such as chemical or fire protective clothing. In summary, the approach provides a moderate fidelity, usable tool which will run on current notebook computers.

  10. All about Eve. Eva Hesse and the Post-Minimalist Romantic Irony

    Directory of Open Access Journals (Sweden)

    Szymański, Wojciech

    2014-03-01

    Full Text Available The article employs the category of Romantic irony for an interpretation of Eva Hesse's work. It takes as its starting point one of Arthur Danto's texts, where the American philosopher makes a positive re-evaluation of the artist's work, and reads it as a largely humorous combination of two – seemingly incongruent – traditions of American art of the 20thcentury: Abstract Expressionism and Minimalism. Features that Danto finds humorous, the author of the present article considers exemplary of Romantic irony, an approach that he finds in Eva Hesse's oeuvre. In the second part of the article, two competing interpretations of Eva Hesse's work are presented: Robert Pincus-Witten's and Lucy R. Lippard's. However, with the use of the notion of Romantic irony their standpoints can be reconciled, with a simultaneous indication of a previously dismissed, yet crucial, ironic aspect of the work of the American artist.

  13. Human Research Program Human Health Countermeasures Element Extravehicular Activity (EVA) Risk Standing Review Panel (SRP)

    Norfleet, William; Harris, Bernard

    2009-01-01

    The Extravehicular Activity (EVA) Risk Standing Review Panel (SRP) was favorably impressed by the operational risk management approach taken by the Human Research Program (HRP) Integrated Research Plan (IRP) to address the stated life sciences issues. The life sciences community at the Johnson Space Center (JSC) seems to be focused on operational risk management. This approach is more likely to provide risk managers with the information they need at the time they need it. Concerning the information provided to the SRP by the EVA Physiology, Systems, and Performance Project (EPSP), it is obvious that a great deal of productive activity is under way. Evaluation of this information was hampered by the fact that it often was not organized in a fashion that reflects the "Gaps and Tasks" approach of the overall Human Health Countermeasures (HHC) effort, and that a substantial proportion of the briefing concerned subjects that, while interesting, are not part of the HHC Element (e.g., the pressurized rover presentation). Additionally, no information was provided on several of the tasks or how they related to work underway or already accomplished. This situation left the SRP having to guess at the efforts and relationship to other elements, and made it hard to easily map the EVA Project efforts currently underway, and the data collected thus far, to the gaps and tasks in the IRP. It seems that integration of the EPSP project into the HHC Element could be improved. Along these lines, we were concerned that our SRP was split off from the other participating SRPs at an early stage in the overall agenda for the meeting. In reality, the concerns of EPSP and other projects share much common ground. For example, the commonality of the concerns of the EVA and exercise physiology groups is obvious, both in terms of what reduced exercise capacity can do to EVA capability, and how the exercise performed during an EVA could contribute to an overall exercise countermeasure prescription.

    Reported herein are results from the Eril Research, Inc.(ERI) participationin the NASA Johnson Space Center sponsored studycharacterizing the radiation shielding properties of the two types ofspace suit that astronauts are wearing during the EVA on-orbit assemblyof the International Space Station (ISS). Measurements using passivedetectors were carried out to assess the shielding properties of the USEMU Suit and the Russian Orlan-M suit during irradiations of the suitsand a tissue equivalent phantom to monoenergetic proton and electronbeams at the Loma Linda University Medical Center (LLUMC). Duringirradiations of 6 MeV electrons and 60 MeV protons, absorbed dose as afunction of depth was measured using TLDs exposed behind swatches of thetwo suit materials and inside the two EVA helmets. Considerable reductionin electron dosewas measured behind all suit materials in exposures to 6MeV electrons. Slowing of the proton beam in the suit materials led to anincrease in dose measured in exposures to 60 MeV protons. During 232 MeVproton irradiations, measurements were made with TLDs and CR-39 PNTDs atfive organ locations inside a tissue equivalent phantom, exposed bothwith and without the two EVA suits. The EVA helmets produce a 13 to 27percent reduction in total dose and a 0 to 25 percent reduction in doseequivalent when compared to measurements made in the phantom head alone.Differences in dose and dose equivalent between the suit and non-suitirradiations forthe lower portions of the two EVA suits tended to besmaller. Proton-induced target fragmentation was found to be asignificant source of increased dose equivalent, especially within thetwo EVA helmets, and average quality factor inside the EMU and Orlan-Mhelmets was 2 to 14 percent greater than that measured in the barephantom head.

O resíduo de EVA moído apresenta duas fases, uma reticulada (matriz e uma não-reticulada (dispersa. O resíduo de EVA apresentou teor de gel de aproximadamente 75% em massa, cerca de 20% em massa de acetato de vinila (VAc, fora processado a partir de EVA com aproximadamente 28% de VAc e possui teor de carga inorgânica de 20% em massa, segundo análises em TGA. O EVA resíduo apresentou maiores valores de módulo elástico e de dureza, e menores valores de elongação na ruptura e de resistência ao impacto Izod. O custo energético da moagem do resíduo de EVA foi calculado como sendo inferior a 5% do valor do EVA virgem.Poly[(ethylene-co-(vinyl acetate] (EVA has large application in the shoes industries, especially as expanded sheets, in order to produce insoles and innersoles. Studies carried out in the south region of Brazil in 2001 have demonstrated that the residues generated by shoes industries were higher than 200 ton/month, the major part of which is composed by EVA expanded sheets. With this in mind, the objective of this work was to characterize the residues of expanded EVA and also to analyze the milling cost in order to make the recycling possible.

  16. An innovative exercise method to simulate orbital EVA work - Applications to PLSS automatic controls

    Science.gov (United States)

    Lantz, Renee; Vykukal, H.; Webbon, Bruce

    1987-01-01

    An exercise method has been proposed which may satisfy the current need for a laboratory simulation representative of muscular, cardiovascular, respiratory, and thermoregulatory responses to work during orbital extravehicular activity (EVA). The simulation incorporates arm crank ergometry with a unique body support mechanism that allows all body position stabilization forces to be reacted at the feet. By instituting this exercise method in laboratory experimentation, an advanced portable life support system (PLSS) thermoregulatory control system can be designed to more accurately reflect the specific work requirements of orbital EVA.

    The curing of cross-linkable encapsulation is a critical consideration for photovoltaic (PV) modules manufactured using a lamination process. Concerns related to ethylene-co-vinyl acetate (EVA) include the quality (e.g., expiration and uniformity) of the films or completion (duration) of the cross-linking of the EVA within a laminator. Because these issues are important to both EVA and module manufacturers, an international standard has recently been proposed by the Encapsulation Task-Group within the Working Group 2 (WG2) of the International Electrotechnical Commission (IEC) Technical Committee 82 (TC82) for the quantification of the degree of cure for EVA encapsulation. The present draft of the standard calls for the use of differential scanning calorimetry (DSC) as the rapid, enabling secondary (test) method. Both the residual enthalpy- and melt/freeze-DSC methods are identified. The DSC methods are calibrated against the gel content test, the primary (reference) method. Aspects of other established methods, including indentation and rotor cure metering, were considered by the group. Key details of the test procedure will be described.

    2008-05-01

    Full Text Available A new way of improving the heat dissipating ability and PV efficiency of the solar cells by enhancing the thermal conductivity of the rear EVA layer was reported. The thermal conductivity, electrical resistivity, degree of curing of the EVA encapsulating composites and the PV efficiency of the solar cells are investigated. Filling with the thermal conductive fillers enhances the thermal conductivity of the composites effectively. The thermal conductivity of the filler influences significantly the thermal conductivity of the composite at high filler loading (greater than 20 vol%. Thermal conductivities of the composites filled with SiC, ZnO or BN reach respectively 2.85, 2.26 and 2.08 W/m•K at filler content of 60 vol%. The composites filled with ZnO or BN exhibit superior electrical insulation to those filled with SiC or Al2O3. ZnO can promote the cross-linking reaction of the EVA matrix. The test results indicated that the EVA composite encapsulating rear films filled with thermal conductive fillers are able to improve the PV efficiency and the heat dissipating ability of the solar cell effectively.

    According to the requirements for neutron shielding and flame retardant properties of some nuclear devices, a new kind of polymer composite materials based on ethylene and vinyl acetate (EVA) polymer have been studied. EVA is the copolymer of ethylene and vinyl acetate, It can be used as materials for applications due to its flexibility, good processability, and low cost. Insulating EVA can be used for cable sheath, automotive sound damping and many other appication. Boron nitride (BN), zinc borate (ZB), magnesium hydroxide (MH) and EVA consisted the compounds with the properties of neutron shielding and flame retardant. With increasing of the contents of BN and ZB, the neutron shielding performance of materials increased up to 33.08%. With the increasing contents of MH and ZB as flame retardant, oxygen index of material have been improved. The elongation at break and tensile strength of material decreased with the increasing of filler powders. Sheet E was chosen and modified by electron beam accelerator in different doses. After modification by electron beam irradiation the sheets showed varying degrees of transformation in the OI, neutron shielding rate and mechanical properties.

    The curing of cross-linkable encapsulation is a critical consideration for photovoltaic (PV) modules manufactured using a lamination process. Concerns related to ethylene-co-vinyl acetate (EVA) include the quality (e.g., expiration and uniformity) of the films or completion (duration) of the cross-linking of the EVA within a laminator. Because these issues are important to both EVA and module manufacturers, an international standard has recently been proposed by the Encapsulation Task-Group within the Working Group 2 (WG2) of the International Electrotechnical Commission (IEC) Technical Committee 82 (TC82) for the quantification of the degree of cure for EVA encapsulation. The present draft of the standard calls for the use of differential scanning calorimetry (DSC) as the rapid, enabling secondary (test) method. Both the residual enthalpy- and melt/freeze-DSC methods are identified. The DSC methods are calibrated against the gel content test, the primary (reference) method. Aspects of other established methods, including indentation and rotor cure metering, were considered by the group. Key details of the test procedure will be described.

    Full Text Available Taking into account the fact that the methodology Value at Risk or the method VaR, which is omnipresent in investment banking and which has lately become a standard in the procedure of evaluating risks for any category of economic activities, we shall use a technique that is compatible with the VaR-market, called Environmental Value at Risk or EvaR. While the VaR- market uses a level of trust of 95%, the EvaR uses a set of levels up to 99,999%. Thus, we shall try to analyze the variables of the method EVaR, and the way in which this model can be applied as a risk of the lack (rarity of petroleum. This risk is not only analyzed as a unique risk of growing the prices, but also as an uncertainty risk on volatile markets, in which the price and the volatility are the main variables used by the function EVaR.

    A new and original method based on carbonyl hydrosilylation was developed to prepare ethylene-vinyl acetate (EVA)/polysiloxane polymer blends. This focused on the addition of hydrogenosilane groups (SiH) from polysiloxane to the carbonyl groups of EVA. The influence of the nature of the polysiloxane on blend properties was investigated by rheology and scanning electron microscopy. Mixing of a low viscosity polysiloxane with a high viscosity EVA matrix produced a two-phase morphology. The occurrence of the hydrosilylation reaction at the EVA/polysiloxane interface promoted a homogenisation of the blend depending on the molar ratio SiH/vinyl acetate groups, [SiH]/[VA], and the viscosity ratio of the blend. Two distinct behaviours were observed. The formation of a crosslinked network under shear was obtained for a low viscosity ratio between polysiloxane and EVA ({lambda}{sub polysiloxane/EVA} = 4.0 Multiplication-Sign 10{sup -6}) with a high concentration of SiH groups ([SiH]/[VA] = 0.5), while the formation of a compatibilised blend was observed for high molar mass polysiloxanes (Mn > 15,000 g mol{sup -1}) with a low concentration of SiH ([SiH]/[VA] < 4.0 Multiplication-Sign 10{sup -3}). -- Highlights: Black-Right-Pointing-Pointer Carbonyl hydrosilylation reaction was found to enhance EVA/polysiloxane immiscible blends. Black-Right-Pointing-Pointer EVA crosslinking was obtained with a low molar mass polysiloxane. Black-Right-Pointing-Pointer EVA compatibilisation was obtained with a high molar mass polysiloxane. Black-Right-Pointing-Pointer Shear rate was found to improve the hydrosilylation reaction at the interface. Black-Right-Pointing-Pointer A two-phase morphology of the blends was observed after reaction with fine polysiloxane nodules.

    Value analysis in health care calculates the economic value added (EVA) that results from improvements in health and health care. Our purpose was to develop an EVA model and to apply the model to typical and hypothetical (instantaneous and perfect) cures for amblyopia, surgical strabismus and asthma, as another, but non-ophthalmological disease standard for comparison, in the United States. The model is based on changes in utility and longevity, the associated incremental costs, and an estimate of the value of life. Univariate sensitivity analyses were performed to arrive at a plausible range of outcomes. For the United States, the EVA for current practice amblyopia care is 12.9B dollars (billion) per year, corresponding to a return on investment (ROI) of 10.4% per yr. With substantial increases in investment aimed at maximal improvement ("perfect cure"), the EVA is 32.7B per yr, with ROI of 5.3% per yr. The EVA for typical surgical strabismus care is 10.3B per yr. A perfect cure may yield EVA of 9.6B per yr. The EVA for asthma is 1317B per yr (ROI 20.4% per yr.., while a perfect cure may yield EVA of 110 B per yr. Sensitivity analysis demonstrated the relatively large effects of incidence, utility, and longevity, while incremental costs have a relatively minor effect on the EVA. The economic value added by improvements in patient-centered outcomes is very large. Failing to make the necessary investments in research, prevention, detection, prompt treatment and rehabilitation of these diseases, at virtually any conceivable cost, appears economically, medically, morally and ethically deficient and consequently wasteful at very least economically for our society.

    During the Apollo Program, space suit outer-layer fabrics were badly abraded after performing just a few extravehicular activities (EVAs). For example, the Apollo 12 commander reported abrasive wear on the boots that penetrated the outer-layer fabric into the thermal protection layers after less than 8 hrs of surface operations. Current plans for the exploration planetary space suits require the space suits to support hundreds of hours of EVA on a lunar or Martian surface, creating a challenge for space suit designers to utilize materials advances made over the last 40 years and improve on the space suit fabrics used in the Apollo Program. Over the past 25 years the NASA Johnson Space Center Crew and Thermal Systems Division has focused on tumble testing as means of simulating wear on the outer layer of the space suit fabric. Most recently, in 2009, testing was performed on 4 different candidate outer layers to gather baseline data for future use in design of planetary space suit outer layers. In support of the High Performance EVA Glove Element of the Next Generation Life Support Project, testing a new configuration was recently attempted in which require 10% of the fabric per replicate of that need in 2009. The smaller fabric samples allowed for reduced per sample cost and flexibility to test small samples from manufacturers without the overhead to have a production run completed. Data collected from this iteration was compared to that taken in 2009 to validate the new test method. In addition the method also evaluated the fabrics and fabric layups used in a prototype thermal micrometeoroid garment (TMG) developed for EVA gloves under the NASA High Performance EVA Glove Project. This paper provides a review of previous abrasion studies on space suit fabrics, details methodologies used for abrasion testing in this particular study, results of the validation study, and results of the TMG testing.

    During lunar excursions in the EVA suit, real-time measurement of metabolic rate is required to manage consumables and guide activities to ensure safe return to the base. Metabolic rate, or oxygen consumption (VO2), is normally measured from pulmonary parameters but cannot be determined with standard techniques in the oxygen-rich environment of a spacesuit. Our group has developed novel near infrared spectroscopic (NIRS) methods to calculate muscle oxygen saturation (SmO 2), hematocrit, and pH, and we recently demonstrated that we can use our NIRS sensor to measure VO 2 on the leg during cycling. Our NSBRI project has 4 objectives: (1) increase the accuracy of the metabolic rate calculation through improved prediction of stroke volume; (2) investigate the relative contributions of calf and thigh oxygen consumption to metabolic rate calculation for walking and running; (3) demonstrate that the NIRS-based noninvasive metabolic rate methodology is sensitive enough to detect decrement in VO 2 in a space analog; and (4) improve instrumentation to allow testing within a spacesuit. Over the past year we have made progress on all four objectives, but the most significant progress was made in improving the instrumentation. The NIRS system currently in use at JSC is based on fiber optics technology. Optical fiber bundles are used to deliver light from a light source in the monitor to the patient, and light reflected back from the patient s muscle to the monitor for spectroscopic analysis. The fiber optic cables are large and fragile, and there is no way to get them in and out of the test spacesuit used for ground-based studies. With complimentary funding from the US Army, we undertook a complete redesign of the sensor and control electronics to build a novel system small enough to be used within the spacesuit and portable enough to be used by a combat medic. In the new system the filament lamp used in the fiber optic system was replaced with a novel broadband near infrared

    This paper describes the effort by the Texas Engineering Experiment Station (TEES) and Honeywell for NASA to design and test a pre-flight prototype pump for use in the Extra-vehicular activity (EVA) portable life support subsystem (PLSS). Major design decisions were driven by the need to reduce the pump s mass, power, and volume compared to the existing PLSS pump. In addition, the pump must accommodate a much wider range of abnormal conditions than the existing pump, including vapor/gas bubbles and increased pressure drop when employed to cool two suits simultaneously. A positive displacement, external gear type pump was selected because it offers the most compact and highest efficiency solution over the required range of flow rates and pressure drops. An additional benefit of selecting a gear pump design is that it is self priming and capable of ingesting non-condensable gas without becoming air locked. The chosen pump design consists of a 28 V DC, brushless, sealless, permanent magnet motor driven, external gear pump that utilizes a Honeywell development that eliminates the need for magnetic coupling. Although the planned flight unit will use a sensorless motor with custom designed controller, the pre-flight prototype to be provided for this project incorporates Hall effect sensors, allowing an interface with a readily available commercial motor controller. This design approach reduced the cost of this project and gives NASA more flexibility in future PLSS laboratory testing. The pump design was based on existing Honeywell designs, but incorporated features specifically for the PLSS application, including all of the key features of the flight pump. Testing at TEES verified that the pump meets the design requirements for range of flow rates, pressure drop, power consumption, working fluid temperature, operating time, gas ingestion , and restart capability under both ambient and vacuum conditions. The pump operated between 40 and 240 lbm/hr flowrate, 35 to 100 F

    2017-03-01

    Full Text Available In recent years, the race for producing biodegradable products has increased tremendously. Different approaches have been attempted to utilise biomass as filler for the production of composites. In this work, biochar from oil palm empty fruit bunch fibre (EFB was used as reinforcing filler. The biochar was produced by pyrolysis of EFB at 700˚C under nitrogen environment. Later, the biochar was added in different ratios up to 40 wt% in PP/EVA/MAPP blend using internal mixer Brabender PL200 twin-screw extruder. The composition ratio of EVA and MAPP was kept constant to 20 wt% and 5wt% respectively. Effects of biochar on the mechanical and thermal properties of the composite were investigated. Results reveal that the addition of 30 wt% biochar enhances thermal properties whilst having no detrimental effect on any mechanical properties. Studies on the morphological properties have shown good compatibility between biochar and polymer matrix at moderate addition of MAPP.

A incorporação dos resíduos, principalmente nas argamassas e concretos, produtos com vasta aplicabilidade no setor, tem se mostrado como uma ótima alternativa na diversificação das matérias-primas e para a economia de recursos naturais. Esse trabalho avaliou as propriedades das argamassas, no estado fresco e endurecido, produzidas com substituição parcial da areia por resíduo de EVA (Ethylene Vinyl Acetate. Para isso, foram preparadas argamassas com teores de substituição do agregado 0% (referência, 5%, 10% e 15%, em massa. A relação água/cimento, para cada traço, foi determinada empiricamente e mantida constante para as argamassas com substituição. Os resultados apontam que as argamassas produzidas com agregado de EVA apresentam menor absorção de água e também um decréscimo da resistência mecânica. Desta forma, a produção de argamassas utilizando EVA em substituição ao agregado natural é viável, todavia é necessário avaliar os parâmetros mínimos de aplicação para cada finalidade. Dessa forma, o trabalho apresenta contribuição ao servir de suporte a gestores de empresas de argamassas ou gestores de obra a tomarem decisões acerca da inserção do resíduo de EVA na produção de argamassa.

  4. Abrasion Testing of Candidate Outer Layer Fabrics for Lunar EVA Space Suits

    Mitchell, Kathryn C.

    2010-01-01

    During the Apollo program, the space suit outer layer fabrics were badly abraded after just a few Extravehicular Activities (EVAs). For example, the Apollo 12 commander reported abrasive wear on the boots, which penetrated the outer layer fabric into the thermal protection layers after less than eight hours of surface operations. Current plans for the Constellation Space Suit Element require the space suits to support hundreds of hours of EVA on the Lunar surface, creating a challenge for space suit designers to utilize materials advances made over the last forty years and improve upon the space suit fabrics used in the Apollo program. A test methodology has been developed by the NASA Johnson Space Center Crew and Thermal Systems Division for establishing comparative abrasion wear characteristics between various candidate space suit outer layer fabrics. The abrasion test method incorporates a large rotary drum tumbler with rocks and loose lunar simulant material to induce abrasion in fabric test cylinder elements, representative of what might occur during long term planetary surface EVAs. Preliminary materials screening activities were conducted to determine the degree of wear on representative space suit outer layer materials and the corresponding dust permeation encountered between subsequent sub -layers of thermal protective materials when exposed to a simulated worst case eight hour EVA. The test method was used to provide a preliminary evaluation of four candidate outer layer fabrics for future planetary surface space suit applications. This Paper provides a review of previous abrasion studies on space suit fabrics, details the methodologies used for abrasion testing in this particular study, and shares the results and conclusions of the testing.

    Full Text Available This paper is devoted to the possibilities of Economic Value Added index usage in the conditions of Czech food-processing industry and is trying to provide independent empirical evidence on the indicator’s qualities. The EVA proponents attach to it a superiority compared to other common performance measures. The aim of this article is to investigate the relationship between Economic Value Added, traditional performance measures (ROA and ROE and ability of creation of shareholder wealth for food-processing firms in the Czech Republic. The way of intended comparison is not dissimilar to the main world studies, which are quoted in this paper. A critical point of the EVA’s application in the conditions of Czech economy is a lack of good quality information from capital market, which at the same time, serve as an exogenous criterion for assessing the quality of the examined measures in the mentioned studies. In the absence of quality capital market information, a criterion for assessing the information content of performance measures suitable for conditions of Czech economy is developed in this paper. This also shows how to circumvent the handicap of the available data.The intent of this article is fulfilled by providing a simple regression test of the hypothesis, that the EVA measure is more associated with improved shareholder wealth than traditional performance measures ROA and ROE. The results of regression analysis show higher quality information content of EVA indicator in the relationship to the ability of shareholder wealth creation than traditional performance measures. This fact supports the tested hypothesis as well as the conclusions of corporate finance theory, that from the theoretical point of view EVA is seen as a superior performance metric.

    2017-02-01

    Full Text Available The transformation of fog at a non-visible water layer on a membrane of low-density polyethylene (LDPE and ethylene-vinyl acetate (EVA was evaluated. Nonionic surfactants of major demand in the polyolefin industry were studied. A kinetic study using a hot fog chamber showed that condensation is controlled by both the diffusion and permanency of the surfactant more than by the change of the surface energy developed by the wetting agents. The greatest permanency of the anti-fog effect of the LDPE/EVA surface was close to 3000 h. The contact angle results demonstrated the ability of the wetting agent to spread out to the surface. Complementarily, the migration of nonionic surfactants from the inside of the polymeric matrix to the surface was analyzed by Fourier transform infrared (FTIR microscopy. Additionally, electrical measurement on the anti-fogging membrane at alternating currents and at a sweep frequency was proposed to test the conductivity and wetting ability of nonionic surfactants. We proved that the amphiphilic molecules had the ability to increase the conductivity in the polyolefin membrane. A correlation between the bulk electrical conductivity and the permanency of the fogging control on the LDPE/EVA coextruded film was found.

  10. Effect of organic peroxides on the morphological, thermal and tensile properties of EVA-organoclay nanocomposites

    Directory of Open Access Journals (Sweden)

    2008-04-01

    Full Text Available Nanocomposites were prepared using an ethylene vinyl acetate copolymer (EVA and organically modified Cloisite® 93A clay in the absence and presence of dicumyl peroxide (DCP and dibenzyl peroxide (DBP as cross-linking agents. The results clearly show differences in the EVA-clay morphology of nanocomposites prepared in the absence of organic peroxides, and of those prepared in the presence of respectively DCP and DBP. It seems as if DCP may initiate grafting between the polymer and the clay, which results in an exfoliated morphology. The presence of clay seems to inhibit the initiation of EVA crosslinking by the DBP free radicals. These free radicals probably initiate hydroxylated edge-edge interaction between the clay layers, which gives rise to a flocculated morphology and reduced polymer-clay interaction. There is a good correlation between these morphologies and the thermal stabilities and total crystallinities of the nanocomposites. Clay incorporation and peroxide treatment did not significantly change the tensile properties.

    Greenisen, Michael C.

    1987-01-01

    The STS Space Suited and unsuited dominant upper limb performance was evaluated in order to quantify future EVA astronaut skeletal muscle upper limb performance expectations. Testing was performed with subjects standing in EVA STS foot restraints. Data was collected with a CYBEX Dynamometer enclosed in a waterproof container. Control data was taken in one g. During one g testing, weight of the Space Suit was relieved from the subject via an overhead crane with a special connection to the PLSS of the suit. Experimental data was acquired during simulated zero g, accomplished by neutral buoyancy in the Weightless Environment Training Facility. Unsuited subjects became neutrally buoyant via SCUBA BC vests. Actual zero g experimental data was collected during parabolic arc flights on board NASA's modified KC-135 aircraft. During all test conditions, subjects performed five EVA work tasks requiring dominant upper limb performance and ten individual joint articulation movements. Dynamometer velocities for each tested movement were 0 deg/sec, 30 or 60 deg/sec and 120 or 180 deg/sec, depending on the test, with three repetitions per test. Performance was measured in foot pounds of torque.

    A high-resolution assessment of health impacts from air pollution and related external cost has been conducted for Denmark using the integrated EVA model system. The EVA system has been further developed by implementing an air quality model with a 1 km x 1 km resolution covering the whole of Denmark. New developments of the integrated model system will be presented as well as results for health impacts and related external costs over several decades. Furthermore, the sensitivity of health impacts to model resolution will be studied. We have developed an integrated model system EVA (Economic Valuation of Air pollution), based on the impact-pathway chain, to assess the health impacts and health-related economic externalities of air pollution resulting from specific emission sources or sectors. The system is used to support policymaking with respect to emission control. In Brandt et al. (2013a; 2013b), the EVA system was used to assess the impacts in Europe and Denmark from the past, present and future total air pollution levels as well as the contribution from the major anthropogenic emission sectors. The EVA system was applied using the hemispheric chemistry-transport model, the Danish Eulerian Hemispheric Model (DEHM), with nesting capability for higher resolution over Europe (50 km x 50 km) and Northern Europe (16.7 km x 16.7 km). In this study an Urban Background Model (UBM) has been further developed to cover the whole of Denmark with a 1 km x 1 km resolution and the model has been implemented as a part of the integrated model system, EVA. The EVA system is based on the impact-pathway methodology. The site-specific emissions will result (via atmospheric transport and chemistry) in a concentration distribution, which together with detailed population data, are used to estimate the population-level exposure. Using exposure-response functions and economic valuations, the exposure is transformed into impacts on human health and related external costs. In this study

    Polymeric nanocomposites have some superior properties when compared to conventional polymer composites and is one of the most promising fields in the nanotechnology research. In a EVA (ethylene vinyl acetate) /PVC (poly vinyl chloride) matrix was incorporated different types of montmorillonite clays (an inorganic (Na{sup +}) and two organic modified (15A and 30B nanoclays). The mixtures were processed in a co-rotating twin-screw extruder at processing speeds of 200 and 400 rpm. Thermogravimetric analysis (TGA) shown that the inorganic and organic modified clays promoted a shift to higher temperatures in the degradation temperature., X-ray diffraction (XRD) and transmission electronic microscopy (TEM) shows a possible intercalation with the 15A clay, exfoliation with the 30B clay and formation of clusters in the Na{sup +} clay. For all clays studied, the increase in shear rate does not promote significant changes. (author)

    2016-09-01

    Full Text Available A new intumescent flame-retardants (IFR system including the charing-foaming agent (CFA, ammonium polyphosphate (APP and modified-layered double hydroxides (LDHs with different transition metals (Ni, Co, Cu were used in the ethylene vinyl acetate (EVA matrix. Both the limiting oxygen index and the vertical burning tests indicate that the CFA/APP system and LDHs have significant synergistic flame retardant effects. The morphology of combustion residues indicates that the many pores of residues can prevent the melt dripping. The thermal analysis shows that the flame retardants obviously enhanced the thermal degradation temperature of ethylene-based chains of the composites. The cone calorimeter test reveals that the CO2 and combustion residues have an important influence on the reduction of heat release rate (HRR, the smoke production rate (SPR, the production rate and the mean release yield of CO. The composite containing Cu (ELDH-Cu delivers an 82% reduction in peak heat release rate, while ELDH-Ni has the best CO suppression among all composites. This work not only confirms the flame retardance and smoke suppression of CFA/APP/LDH/EVA, but also provides an effective method for producing new flame retardants and smoke suppressants.

    The synergistic effect of organo-modified montmorillonite (Nanomer I28E and Cloisite 20A) and metal hydroxides (magnesium hydroxide MH and alumina trihydrate ATH) as flame retardants in LDPE/EVA nanocomposites compatibilized with amino alcohol grafted polyethylene (PEgDMAE) was studied. Morphological characterization of nanocomposites was carried out by means of X-ray diffraction (XRD) and scanning transmission electron microscopy (STEM). Flame-retardant properties of nanocomposites were evaluated by the UL-94 horizontal burning and cone calorimeter tests and limiting oxygen index (LOI). Thermal degradation behavior was analyzed with a Fourier transform infrared coupled with the thermogravimetric analyzer (TG-FTIR). The XRD analysis showed a displacement of the d{sub 001} plane characteristic peak of clay to lower angles, which indicates an intercalated–exfoliated morphology. From STEM images it was observed a good dispersion of flame retardants (MH and ATH) throughout the polymer matrix which was reflected in flame-retardant properties. TG-FTIR showed a better thermal stability of nanocomposites and the gases evolved during combustion showed an important reduction. Based on thermal stability and thermal degradation results, the flame-retardant mechanism of LDPE/PEgDMAE/EVA/Clay/MH nanocomposites was proposed. - Highlights: • We evaluated the synergistic effect of MMT clay and nano-metallic hydroxides for wire coating applications. • We analyzed the using of a new type of polymer-inorganic compatibilizer. • We proposed a new flame-retardant mechanism for polymer blends/Clay/MH nanocomposites.

    The surface free energy of polymeric films of polyvinylchloride (PVC) + poly(ethylene-co-vinylacetate) (EVA) blends was calculated using the van Oss treatment (Lifshitz and electron donor-electron acceptor components of surface free energy) and the Owens-Wendt treatment (dispersive and nondispersive components of surface free energy). Surface free energy results were found to be greatly dependent on the calculation method and on the number of standard liquids used for contact angle measurements. The nondispersive/donor-acceptor surface free energy component and the total surface free energy of polymeric films were always higher when the van Oss treatment was used compared to the Owens-Wendt treatment. Conversely, both methods led to similar apolar/Lifshitz components. All the calculation methods were in good agreement for the surface free energy of PVC; however, a discrepancy between the methods arose as EVA content in the blends increased. It seems that there is not yet a definite solution for the calculation of solid surface free energy. Further developments of existing models are needed in order to gain consistency when calculating this important physicochemical quantity. Copyright 1998 Academic Press.

    Full Text Available The need for a permanent market supply of fresh fruit has generated great interest in postharvest techniques that can promote useful life and quality of the fruit. The aim of this study was to evaluate the efficiency of atmospheric modification using different polymeric films in maintaining postharvest quality and prolonging the shelf life of Eva (Mallus sp apples. For this, fruits from the city of Barbacena - MG, selected and sanitized were packed in plastic trays and wrapped in the corresponding films. The films used were: polypropylene - 20 µm, low-density polyethylene - 14 µm and high-density polyethylene - 7 µm. Another group of fruits (control was not submitted to a modified atmosphere. Subsequently, all the the packages were stored under refrigeration (0 ° C ± 0.5 for 210 days and the evaluations of the following variables were performed every 30 days of storage: hydrogen potential (pH, titratable acidity, soluble solids, weight loss, firmness, total pectin, soluble pectin, pectin methyl esterase and polygalacturonase. The work was conducted in a completely randomized design (4x8, with 4 treatments and 8 experimental times. Each treatment consisted of three replicates and each experimental unit consisted of six fruits. The results were submitted to variance analysis and means were compared by the Tukey test at 5% probability and regression analysis. The low density polyethylene (14 µm packaging provided the best conservation of the Eva cultivar apple textural characteristics.

  9. Synergistic flame retardant effects between sepiolite and magnesium hydroxide in ethylene-vinyl acetate (EVA matrix

    2010-04-01

    Full Text Available Some customers are reluctant to change, because the halogen-free solutions may have higher cost. This is one of the reasons that the synergistic effect is always the subject for researchers to pursue. The synergy between sepiolite and magnesium hydroxide (MH in halogen-free flame retardant ethylene-vinyl acetate (EVA copolymer was investigated in the paper through some common facilities, such as limiting oxygen index (LOI, UL-94 test, thermogravimetric analysis (TGA, differential thermal analysis (DTA and cone calorimeter test (CCT. In the wake of the positive results from the LOI and UL-94 tests, the CCT data indicated not only the reduction of heat release rate (HRR and mass loss rates (MLR, but also prolonged ignition time (TTI and depressed smoke release (SR were observed during combustion. Simultaneously, the tensile strength and Young’s modulus of the system were also much better improved with the increase of sepiolite added due to the hydrogen bonds between silanol groups attached to the sepiolite molecules and the ester groups of EVA. The synergistic mechanism has been discussed in the paper in terms of the barrier mechanism in the condensed phase.

    The purpose of this project was to aid the EVA Robotic Assistant project by evaluating and designing the necessary interfaces for two stereo vision heads - the TracLabs Biclops pan-tilt-verge head, and the Helpmate Zebra pan-tilt-verge head. The first half of the project consisted of designing the necessary software interface so that the other modules of the EVA Robotic Assistant had proper access to all of the functionalities offered by each of the stereovision heads. This half took most of the project time, due to a lack of ready-made CORBA drivers for either of the heads. Once this was overcome, the evaluation stage of the project began. The second half of the project was to take these interfaces and to evaluate each of the stereo vision heads in terms of usefulness to the project. In the key project areas such as stability and reliability, the Zebra pan-tilt-verge head came out on top. However, the Biclops did have many more advantages over the Zebra, such as: lower power consumption, faster communications, and a simpler, cleaner API. Overall, the Biclops pan-tilt-verge head outperformed the Zebra pan-tilt-verge head.

    In November 2004, NASA's Space Shuttle Program approved the development of the Extravehicular (EVA) Infrared (IR) Camera to test the application of infrared thermography to on-orbit reinforced carbon-carbon (RCC) damage detection. A multi-center team composed of members from NASA's Johnson Space Center (JSC), Langley Research Center (LaRC), and Goddard Space Flight Center (GSFC) was formed to develop the camera system and plan a flight test. The initial development schedule called for the delivery of the system in time to support STS-115 in late 2005. At the request of Shuttle Program managers and the flight crews, the team accelerated its schedule and delivered a certified EVA IR Camera system in time to support STS-114 in July 2005 as a contingency. The development of the camera system, led by LaRC, was based on the Commercial-Off-the-Shelf (COTS) FLIR S65 handheld infrared camera. An assessment of the S65 system in regards to space-flight operation was critical to the project. This paper discusses the space-flight assessment and describes the significant modifications required for EVA use by the astronaut crew. The on-orbit inspection technique will be demonstrated during the third EVA of STS-121 in September 2005 by imaging damaged RCC samples mounted in a box in the Shuttle's cargo bay.

    Extravehicular activity (EVA) of astronauts during space missions is simulated nowadays underwater in neutral buoyancy facilities. Certain aspects of weightlessness can be reproduced underwater by adding buoyancy to a diver-astronaut, therefore exposing the subject to the difficulties of working without gravity. Such tests were done at the COMEX' test pool in Marseilles in the 1980s to train for a French-Russian mission to the MIR station, for the development of the European HERMES shuttle and the COLUMBUS laboratory. However, space agencies are currently studying missions to other destinations than the International Space Station in orbit, such as the return to the Moon, NEO (near-Earth objects) or Mars. All these objects expose different gravities: Moon has one sixth of Earth's gravity, Mars has a third of Earth's gravity and asteroids have virtually no surface gravity; the astronaut "floats" above the ground. The preparation of such missions calls for a new concept in neutral buoyancy training, not on man-made structures, but on natural terrain, underwater, to simulate EVA operations such as sampling, locomotion or even anchoring in low gravity. Underwater sites can be used not only to simulate the reduced gravity that astronauts will experience during their field trips, also human factors like stress are more realistically reproduced in such environment. The Bay of Marseille hosts several underwater sites that can be used to simulate various geologic morphologies, such as sink-holes which can be used to simulate astronaut descends into craters, caves where explorations of lava tubes can be trained or monolithic rock structures that can be used to test anchoring devices (e.g., near Earth objects). Marseilles with its aerospace and maritime/offshore heritage hosts the necessary logistics and expertise that is needed to perform such simulations underwater in a safe manner (training of astronaut-divers in local test pools, research vessels, subsea robots and

    Full Text Available Abstract Background Whole exome sequencing (WES has become the strategy of choice to identify a coding allelic variant for a rare human monogenic disorder. This approach is a revolution in medical genetics history, impacting both fundamental research, and diagnostic methods leading to personalized medicine. A plethora of efficient algorithms has been developed to ensure the variant discovery. They generally lead to ~20,000 variations that have to be narrow down to find the potential pathogenic allelic variant(s and the affected gene(s. For this purpose, commonly adopted procedures which implicate various filtering strategies have emerged: exclusion of common variations, type of the allelics variants, pathogenicity effect prediction, modes of inheritance and multiple individuals for exome comparison. To deal with the expansion of WES in medical genomics individual laboratories, new convivial and versatile software tools have to implement these filtering steps. Non-programmer biologists have to be autonomous combining themselves different filtering criteria and conduct a personal strategy depending on their assumptions and study design. Results We describe EVA (Exome Variation Analyzer, a user-friendly web-interfaced software dedicated to the filtering strategies for medical WES. Thanks to different modules, EVA (i integrates and stores annotated exome variation data as strictly confidential to the project owner, (ii allows to combine the main filters dealing with common variations, molecular types, inheritance mode and multiple samples, (iii offers the browsing of annotated data and filtered results in various interactive tables, graphical visualizations and statistical charts, (iv and finally offers export files and cross-links to external useful databases and softwares for further prioritization of the small subset of sorted candidate variations and genes.

    A model-based, distributed architecture integrates diverse components in a system designed for lunar and planetary surface operations: spacesuit biosensors, cameras, GPS, and a robotic assistant. The system transmits data and assists communication between the extra-vehicular activity (EVA) astronauts, the crew in a local habitat, and a remote mission support team. Software processes ("agents"), implemented in a system called Brahms, run on multiple, mobile platforms, including the spacesuit backpacks, all-terrain vehicles, and robot. These "mobile agents" interpret and transform available data to help people and robotic systems coordinate their actions to make operations more safe and efficient. Different types of agents relate platforms to each other ("proxy agents"), devices to software ("comm agents"), and people to the system ("personal agents"). A state-of-the-art spoken dialogue interface enables people to communicate with their personal agents, supporting a speech-driven navigation and scheduling tool, field observation record, and rover command system. An important aspect of the engineering methodology involves first simulating the entire hardware and software system in Brahms, and then configuring the agents into a runtime system. Design of mobile agent functionality has been based on ethnographic observation of scientists working in Mars analog settings in the High Canadian Arctic on Devon Island and the southeast Utah desert. The Mobile Agents system is developed iteratively in the context of use, with people doing authentic work. This paper provides a brief introduction to the architecture and emphasizes the method of empirical requirements analysis, through which observation, modeling, design, and testing are integrated in simulated EVA operations.

    2000-01-01

    BACKGROUND: Nonuniform heating and cooling of the body, a possibility during extended duration extravehicular activities (EVA), was studied by means of a specially designed water circulating garment that independently heated or cooled the right and left sides of the body. The purpose was to assess whether there was a generalized reaction on the finger in extreme contradictory temperatures on the body surface, as a potential heat status controller. METHOD: Eight subjects, six men and two women, were studied while wearing a sagittally divided experimental garment with hands exposed in the following conditions: Stage 1 baseline--total body garment inlet water temperature at 33 degrees C; Stage 2--left side inlet water temperature heated to 45 degrees C; right side cooled to 8 degrees C; Stage 3--left side inlet water temperature cooled to 8 degrees C, right side heated to 45 degrees C. RESULTS: Temperatures on each side of the body surface as well as ear canal temperature (Tec) showed statistically significant Stage x Side interactions, demonstrating responsiveness to the thermal manipulations. Right and left finger temperatures (Tfing) were not significantly different across stages; their dynamic across time was similar. Rectal temperature (Tre) was not reactive to prevailing cold on the body surface, and therefore not informative. Subjective perception of heat and cold on the left and right sides of the body was consistent with actual temperature manipulations. CONCLUSIONS: Tec and Tre estimates of internal temperature do not provide accurate data for evaluating overall thermal status in nonuniform thermal conditions on the body surface. The use of Tfing has significant potential in providing more accurate information on thermal status and as a feedback method for more precise thermal regulation of the astronaut within the EVA space suit.

    One of the most widely used techniques for solving the drawback caused by the deposition of paraffin crystals as observed in the petroleum industry is the use of organic deposition inhibitors - ODI's. This work aims at the development of polymeric materials to be employed as ODI's for crudes and middle distillate petroleum oils, such as lube oils. To this purpose, commercial ethylene-co-vinyl acetate (EVA) copolymers were submitted to chemical modifications involving esterification reactions with long chain organic acid chlorides, the amount of which being varied in order to obtain materials of different side chain contents. The resulting products were tested as lube oil additives, and the oils had their pour points assessed. Results showed that the chemically modified copolymers had a more pronounced influence in the paraffin crystallization process, leading to a more accentuated decrease in the lube oil pour point, than the non-modified EVA commercial sample.

    Full Text Available Thermochromic films based on vanadium dioxide (VO2/ethylene vinyl acetate copolymer (EVA composite were developed. The monoclinic VO2 particles was firstly prepared via hydrothermal and calcination processes. The effects of hydrothermal time and tungsten doping agent on crystal structure and morphology of the calcined metal oxides were reported. After that, 1 wt % of the prepared VO2 powder was mixed with EVA compound, using two different mixing processes. It was found that mechanical properties of the EVA/VO2 films prepared by the melt process were superior to those of which prepared by the solution process. On the other hand, percentage visible light transmittance of the solution casted EVA/VO2 film was greater than that of the melt processed composite film. This was related to the different gel content of EVA rubber and state of dispersion and distribution of VO2 within the polymer matrix phase. Thermochromic behaviors and heat reflectance of the EVA/VO2 film were also verified. In overall, this study demonstrated that it was possible to develop a thermochromic film using the polymer composite approach. In this regard, the mixing condition was found to be one of the most important factors affecting morphology and thermo-mechanical properties of the films.

    Integrated models which are used to account for the external costs of air pollution have to a considerable extent ignored the non-linear dynamics of atmospheric science. In order to bridge the gap between economic analysis and environmental modelling an integrated model EVA, based on a Eulerian...... atmospheric module for regional transport and chemical transformation of air pollutants, has been developed. The EVA model follows the impact-pathway approach of the ExternE-project, but provides damage estimates which are more consistent with the laws of physics and chemistry. In this paper the significance...... for the final external cost estimates of the Eulerian approach is explored. Uncertainties in the health costs estimates are endemic in particular for mortality, but in order to achieve a common baseline the approach recommended by the OECD has been employed for the valuation part.

    Robonaut 2 (R2) has completed its fixed base activities on-board the ISS and is scheduled to receive its climbing legs in early 2014. In its continuing line of firsts, the R2 torso finished up its on-orbit activities on its stanchion with the manipulation of space blanket materials and performed multiple tasks under teleoperation control by IVA astronauts. The successful completion of these two IVA experiments is a key step in Robonaut's progression towards an EVA capability. Integration with the legs and climbing inside the ISS will provide another important part of the experience that R2 will need prior to performing tasks on the outside of ISS. In support of these on-orbit activities, R2 has been traversing across handrails in simulated zero-g environments and working with EVA tools and equipment on the ground to determine manipulation strategies for an EVA Robonaut. R2 made significant advances in robotic manipulation of deformable materials in space while working with its softgoods task panel. This panel features quarter turn latches that secure a space blanket to the task panel structure. The space blanket covers two cloth cubes that are attached with Velcro to the structure. R2 was able to open and close the latches, pull back the blanket, and remove the cube underneath. R2 simulated cleaning up an EVA worksite as well, by replacing the cube and reattaching the blanket. In order to interact with the softgoods panel, R2 has both autonomously and with a human in the loop identified and localized these deformable objects. Using stereo color cameras, R2 identified characteristic elements on the softgoods panel then extracted the location and orientation of the object in its field of view using stereo disparity and kinematic transforms. R2 used both vision processing and supervisory control to successfully accomplish this important task. Teleoperation is a key capability for Robonaut's effectiveness as an EVA system. To build proficiency, crewmembers have

    The interface width determination through the construction of composition density profile across the interface in an immiscible binary polymer blend using ortho-positronium lifetime parameters is described in this paper. The distribution of free volume and hence the hydrodynamic interaction parameter has been evaluated for this purpose making use of the CONTIN routine analysis of the lifetime spectra. The results showed the broad free volume distribution and narrow interface width were reminiscent of lack of interaction between SAN and EVA the constituents.

    In this paper a series of low-density polyethylene (LDPE) blends with different percentages (10%, 20%, and 30%) of EVA and sets of low-density polyethylene sheets were prepared. This set consists of four subsets, which were made under different cooling methods: fast cooling in liquid nitrogen, cooling with cassette, exposing in open air, and cooling in oven, to investigate the crystallinity effects. All of the samples were irradiated with 10 MeV electron-beam in the dose range of 0-250 kGy using a Rhodotron accelerator system. The variation of thermal conductivity (k) and specific heat capacity (C{sub p}) of all of the samples were measured. We found that, for the absorption dose less than 150 kGy, k of the LDPE samples at a prescribed temperature range decreased by increasing the amount of dose, but then the change is insignificant. With increasing the crystallinity, k of the LDPE samples increased, whereas C{sub p} of this material is decreased. In the case of LDPE/EVA blends, for the dose less than 150 kGy, C{sub p} (at 40 Degree-Sign C) and k (in average) decreased, but then the change is insignificant. With increasing the amount of additive (EVA), C{sub p} and k increased.

    Full Text Available Abstract Green roofs can contribute in many ways to the quality of the environment, being known for reducing the heat transfer to the interior of the buildings. Amongst the available techniques for the execution of this type of covering, the use of light cement blocks which are compatible with the system of extensive modular green roofs is proposed. For the light cement blocks, produced with EVA aggregates (waste from the footwear industry, an additional contribution in the capacity of thermal insulation of the proposed green roof is expected. In the present article, the demonstration of such contribution is intended through measurements carried out in prototypes in hot and humid climates. After characterizing the capacity of thermal insulation of the proposed green roof, with different types of conventional covering as a reference, an additional contribution of the component used in this green roof was identified by making comparisons with measurements collected from another green roof, executed with cement blocks without the presence of the EVA aggregates. In the experiments, external and internal surface temperatures were measured in each of the prototypes' coverings, as well as the air temperatures in the internal and external environments. From the analysis of the data for a typical summer day, it was possible to prove that the proposed green roof presented the lowest temperature ranges, considering the internal air and surface temperatures. The presence of the EVA aggregates in the proposed blocks contributed to the decrease of the internal temperatures.

As we understand it, the historical-literary revision put forward by this author may be spotlighted not only through his unique use of a humorous register, but also through an analysis focusing on the configuration of the Revolutionary Tendency centered around the taxonomy of an “us” and a “them” outlined by Eva Perón in Mi mensaje (My Message, 1952.

    Full Text Available Thymoquinone (Tq has been reported to potentiate the in vitro growth-inhibitory activity of some antibiotics especially against Staphylococcus aureus. However, it has been shown that Tq vapors can affect the results of susceptibility testing by standard broth microdilution method. Therefore, we made a comparative experiment with and without ethylene vinyl acetate cap mats (EVA capmat™ on microplates. The results showed significant differences in the minimum inhibitory concentration values and proved this capmat as an effective vapor barrier. Therefore further experiments focused on the in vitro anti-staphylococcal combinatory effect of Tq with oxacillin, penicillin, and tetracycline against various S. aureus strains have been performed by checkerboard method using EVA capmat™. The combined effect was evaluated according to the sum of fractional inhibitory concentrations (ΣFIC. Synergy was obtained for combination with oxacillin against 3 (ΣFIC 0.263–0.450, with penicillin against 1 (ΣFIC 0.466 and with tetracycline against 2 strains tested (ΣFIC 0.400–0.475. Our results confirm previous reports on the Tq enhancement of anti-staphylococcal activity of antibiotics. Moreover, this is the first report on Tq synergy with oxacillin and penicillin against S. aureus. Our experiments also showed that Tq vapors can affect evaluation of combined effect by checkerboard assay, whereas the use of EVA capmat™ can avoid this.

    The Biologic Analog Science Associated with Lava Terrains (BASALT) project is a four-year program dedicated to iteratively designing, implementing, and evaluating concepts of operations (ConOps) and supporting capabilities to enable and enhance scientific exploration for future human Mars missions. The BASALT project has incorporated three field deployments during which real (non-simulated) biological and geochemical field science have been conducted at two high-fidelity Mars analog locations under simulated Mars mission conditions, including communication delays and data transmission limitations. BASALT's primary Science objective has been to extract basaltic samples for the purpose of investigating how microbial communities and habitability correlate with the physical and geochemical characteristics of chemically altered basalt environments. Field sites include the active East Rift Zone on the Big Island of Hawai'i, reminiscent of early Mars when basaltic volcanism and interaction with water were widespread, and the dormant eastern Snake River Plain in Idaho, similar to present-day Mars where basaltic volcanism is rare and most evidence for volcano-driven hydrothermal activity is relict. BASALT's primary Science Operations objective has been to investigate exploration ConOps and capabilities that facilitate scientific return during human-robotic exploration under Mars mission constraints. Each field deployment has consisted of ten extravehicular activities (EVAs) on the volcanic flows in which crews of two extravehicular and two intravehicular crewmembers conducted the field science while communicating across time delay and under bandwidth constraints with an Earth-based Mission Support Center (MSC) comprised of expert scientists and operators. Communication latencies of 5 and 15 min one-way light time and low (0.512 Mb/s uplink, 1.54 Mb/s downlink) and high (5.0 Mb/s uplink, 10.0 Mb/s downlink) bandwidth conditions were evaluated.

    NASA is developing new portable life support system (PLSS) technologies, which it is demonstrating in an unmanned ground based prototype unit called PLSS 2.0. One set of technologies within the PLSS provides suitable ventilation to an astronaut while on an EVA. A new component within the ventilation gas loop is a liquid-to-gas heat exchanger to transfer excess heat from the gas to the thermal control system s liquid coolant loop. A unique bench top prototype heat exchanger was built and tested for use in PLSS 2.0. The heat exchanger was designed as a counter-flow, compact plate fin type using stainless steel. Its design was based on previous compact heat exchangers manufactured by United Technologies Aerospace Systems (UTAS), but was half the size of any previous heat exchanger model and one third the size of previous liquid-to-gas heat exchangers. The prototype heat exchanger was less than 40 cubic inches and weighed 2.57 lb. Performance of the heat exchanger met the requirements and the model predictions. The water side and gas side pressure drops were less 0.8 psid and 0.5 inches of water, respectively, and an effectiveness of 94% was measured at the nominal air side pressure of 4.1 psia.

  9. ‘With Courteous and Careful Eyes’: Eva Bourke’s Ekphrases

    Megan Buckley

    2014-03-01

    Full Text Available This article considers the function of ekphrasis – which can be defined as the verbal representation of a visual representation – in the work of Irish poet Eva Bourke. The visual arts have featured prominently across much of Bourke’s work, and her ekphrastic poems, which eschew the traditionally gendered interpretations of ekphrasis that privilege “masculine” narrative over “feminine” image, suggest that the ekphrastic act develops differently when performed by a woman writer. Her poems celebrate the presence of the minute and detailed: a practice of looking that is born of disciplined, precise observation, and they often reflect upon painterly representations of domestic interiors and household items, valuing them for their usefulness and simplicity as well as their beauty. Moreover, the way in which Bourke approaches visual art embraces disorder and the “disjointed,” and takes into account the location of the artwork, suggesting that the ekphrastic encounter is not limited to a single gaze between poet and art object. Bourke’s art poems offer readers a multidimensional version of the ekphrastic experience, and demonstrate that ekphrasis continues to be a way for women poets in particular to examine anxieties that arise from questions of nationality and gender.

    Scientist-Astronaut Harrison Schmitt, Apollo 17 lunar module pilot, uses an adjustable sampling scoop to retrieve lunar samples during the second Apollo 17 extravehicular activity (EVA-2), at Station 5 at the Taurus-Littrow landing site. A gnomon is atop the large rock in the foreground. The gnomon is a stadia rod mounted on a tripod, and serves as an indicator of the gravitational vector and provides accurate vertical reference and calibrated length for determining size and position of objects in near-field photographs. The color scale of blue, orange and green is used to accurately determine color for photography. The rod of it is 18 inches long. The scoop Dr. Schmitt is using is 11 3/4 inches long and is attached to a tool extension which adds a potential 30 inches of length to the scoop. The pan portion, obscured in this view, has a flat bottom, flanged on both sides with a partial cover on the top. It is used to retrieve sand, dust and lunar samples too small for the tongs. The pa

    The principal plastic materials used for the fluid contact and storage in the biopharmaceutical industry are mainly made up of semi-crystalline polymers, polyolefins, PVC, Siloxane and PET. The polyethylene (PE) and the polypropylene (PP) are often used as fluid contact in multi-layer materials like films. As one sterilisation way of single-use plastic devices used in medical and pharmaceutical fields can take place via γ-irradiation, the effect of sterilization on plastics must be investigated. The irradiation process leads to the production of radicals, which can generate changes in the polymer structure and on the polymer surface. It is well known that the presence of oxygen with free radicals precede the generation of peroxide species so called ROS (reactive oxygen species) which are highly reactive. The purpose of this work is to investigate the γ-rays impact on the surface of PE (polyethylene) and EVA (polyethylene vinyl alcohol) based films when ionized at different doses. X-ray Photoelectron Spectroscopy (XPS) was applied to determine the surface compositions of the polymers to highlight the different chemical moieties generated during the γ-irradiation process and to monitor the potential presence of the ROS.

    2009-01-01

    Earned Value Management (EVM), like project management, is as much art as it is science to develop an implementation plan for a project. This presentation will cover issues that were overcome and the implementation strategy to deploy Earned Value Management (EVM) within the Constellation Program (CxP), EVA Systems Project Office (ESPO), as well as discuss additional hurdles that currently prevent the organization from optimizing EVM. Each organization and each project within an organization needs to mold an EVM implementation plan around existing processes and tools, while at the same time revising those existing processes and tools as necessary to make them compatible with EVM. The ESPO EVM implementation covers work breakdown structure, organizational breakdown structure, control account, work/planning package development; integrated master schedule development using an integrated master plan; incorporating reporting requirements for existing funding process such as Planning, Programming, Budgeting, and Execution (PPBE) and JSC Internal Task Agreements (ITA); and interfacing with other software tools such as the Systems Applications and Products (SAP) accounting system and the CxP wInsight EVM analysis tool. However, there are always areas for improvement and EVM is no exception. As EVM continues to mature within the NASA CxP, these areas will continue to be worked to resolution to provide the Program Managers, Project Managers, and Control Account Managers the best EVM data possible to make informed decisions.

    Full Text Available A evasão consiste num problema importante no âmbito educacional por causar ociosidade de recursos. O PROUNI (Programa Universidade para Todos e o FIES (Financiamento Estudantil têm subsidiado o ingresso de estudantes em Instituições de Ensino Superior (IES privadas. Esses incentivos minimizam a motivação financeira que pode gerar evasão. O objetivo desta pesquisa foi verificar o efeito da concessão de bolsas do PROUNI e FIES na contenção da evasão. Com análise de dados em painéis estimou-se quatro modelos, sendo significante o modelo por efeitos aleatórios. Os resultados apontaram que as bolsas ofertadas pelo PROUNI têm correlação negativa com a evasão e, com menor magnitude, o FIES apresentou relação positiva. Desta forma, conclui-se que o PROUNI se apresenta como uma política mais eficaz à contenção da evasão do que o FIES.

  16. Assessment and Management of the Risks of Debris Hits During Space Station EVAs

    Pate-Cornell, Elisabeth; Sachon, Marc

    1997-01-01

    The risk of EVAs is critical to the decision of whether or not to automate a large part of the construction of the International Space Station (ISS). Furthermore, the choice of the technologies of the space suit and the life support system will determine (1) the immediate safety of these operations, and (2) the long-run costs and risks of human presence in space, not only in lower orbit (as is the case of the ISS) but also perhaps, outside these orbits, or on the surface of other planets. The problem is therefore both an immediate one and a long-term one. The fundamental question is how and when to shift from the existing EMU system (suit, helmet, gloves and life support system) to another type (e.g. a hard suit), given the potential trade-offs among life-cycle costs, risks to the astronauts, performance of tasks, and uncertainties about new systems' safety inherent to such a shift in technology. A more immediate issue is how to manage the risks of EVAs during the construction and operation of the ISS in order to make the astronauts (in the words of the NASA Administrator) "as safe outside as inside". For the moment (June 1997), the plan is to construct the Space Station using the low-pressure space suits that have been developed for the space shuttle. In the following, we will refer to this suit assembly as EMU (External Maneuvering Unit). It is the product of a long evolution, starting from the U.S. Air Force pilot suits through the various versions and changes that occurred for the purpose of NASA space exploration, in particular during the Gemini and the Apollo programs. The Shuttle EMU is composed of both soft fabrics and hard plates. As an alternative to the shuttle suit, at least two hard suits were developed by NASA: the AX5 and the MRKIII. The problem of producing hard suits for space exploration is very similar to that of producing deep-sea diving suits. There was thus an opportunity to develop a suit that could be manufactured for both purposes with the

    1995-07-01

    The ultrasonic bubble detection technique has been used as a versatile tool in the investigation of hypobaric decompression procedures for the last two decades. However, this method can only detect relatively large bubbles30-50 μm (usually in venous blood) and not the very first stages of bubble formation. Recently, the mechanical oscillator technique has been applied in air diving trials in order to detect small blood density changes due to hypothetical fluid shifts. However, sharp density drops were found in the decompression process, and these have been attributed to gas bubble formation. In this study, this method was applied together with Doppler controls to a series of altitude decompressions to 300 and 500 hPa, which represents the range of EVA operational pressures currently used or planned. Six subjects participated in both series; the oscillator sample tube could be pressurized. By the application of pressure on a blood sample containing questionable gas bubbles, these are reduced in volume, like in recompression therapy, and thus the density of the sample is increased. This effect has been shown in all 6 subjects undergoing decompression to 300 hPa, whereas in the 500 hPa series only 3 out of 6 subjects corresponded with gas phase formation immediately after decompression. Typically, Doppler bubbles appeared only after some latency time between 20 and 60 min; after this time, the density effect had nearly vanished. It is concluded that the mechanical oscillator technique represents a complementary research instrument to the Doppler method, because it is able to deliver a quantitative resolution of the early stage of gas phase formation.

  18. Affect and Nostalgia in Eva Hoffman’s Lost in Translation

    Full Text Available This article examines the affective terrain of Poland, Canada, and the US in Eva Hoffman’s autobiographical account of her migration and exile in Lost in Translation: A Life in a New Language (1989, the text that launched Hoffman’s reputation as a writer and intellectual. Hoffman’s Jewish family left Poland for Vancouver in 1959, when restrictions on emigration were lifted. Hoffman was 13 when she emigrated to Canada, where she lived until she went to college in the US and began her career. Lost in Translation represents her trajectory in terms of “Paradise,” “Exile,” and “The New World,” and the narrative explicitly thematizes nostalgia. While Hoffman’s nostalgia for post-war Poland has sometimes earned censure from critics who draw attention to Polish anti-Semitism and the failings of Communism, this article stresses how Hoffman’s nostalgia for her Polish childhood is saturated with self-consciousness and an awareness of the politics of remembering and forgetting. Thus, Hoffman’s work helps nuance the literary and critical discourse on nostalgia. Drawing on theories of nostalgia and affect developed by Svetlana Boym and Sara Ahmed, and on Adriana Margareta Dancus’s notion of “affective displacement,” this article examines Hoffman’s complex understanding of nostalgia. It argues that nostalgia in Lost in Translation is conceived as an emotion which offers the means to critique cultural practices and resist cultural assimilation. Moreover, the lyricism of Hoffman’s autobiography becomes a mode for performing the ambivalence of nostalgia and diasporic feeling.

  19. Enlarged vestibular aqueduct (EVA) related with recurrent benign paroxysmal positional vertigo (BPPV).

    The vestibular aqueduct is a bony canal related to the bony labyrinth of the inner ear and represents the non-sensory components of the endolymph-filled, closed, membranous labyrinth. The association of congenital sensorineural hearing loss with a large or enlarged vestibular aqueduct is well known as the large vestibular aqueduct syndrome (LVAS). The enlarged VA (EVA) comprises abnormalities not only in the structure of the inner ear, but also in the physiology of the auditory and vestibular systems. The clinical picture of this clinical entity is variable [Yetiser S, Kertment M, Ozkaptan Y. Vestibular disturbance in patients with Large Vestibular Aqueduct Syndrome (LVAS). Acta Otolaryngol (StochK) 1999;119: 641-646]. Signs and symptoms of the auditory impairment are more commonly described in the literature: hearing loss ranges from mild to profound, arising from fluctuating to stepwise progressive or sudden. Vestibular disturbances, ranging from mild imbalance to episodic vertigo, are rarely described in the literature. Benign paroxysmal positional vertigo (BPPV) is a labyrinthine disorder with a typical behavior: intense crises of rotational vertigo induced by postural changes of the head, with short duration and usually good responsiveness to rehabilitative maneuvers. These maneuvers are effective in about 80% of patients with BPPV. BPPV often recurs. About 1/3 of patients have a recurrence in the first year after treatment, and by five years, about half of all patients have a recurrence. Vestibular aqueduct has been demonstrated by conventional tomography and computed tomography (CT), however, CT scans cannot show the membranous labyrinth itself. On MR images it is not the vestibular aqueduct that is visualized but its contents, the endolymphatic duct and sac, and can show the abnormalities of the fluid spaces related to the membranous labyrinth. It is proposed that recurrent benign paroxysmal positional vertigo (BPPV) is related with volumetric abnormalities

    Several techniques have been used to minimize the problems caused by the wax deposition, and the continuous addition of polymeric inhibitors is considered an attractive technological alternative. The addition of copolymers like polyacrylates, polymethacrylates or poly(ethylene-co-vinyl acetate) (EVA) permit to inhibit the deposition phenomenon; nonetheless, this effect is specific, i.e. similar copolymers present different performance depending on their physical-chemical properties in solution. In this work, the influence of the EVA vinyl acetate content on the viscosity and the pour point of a Brazilian crude oil were evaluated. A correlation between both results was also obtained. The phase behavior and the solubility parameter of EVA copolymers, with different vinyl acetate contents, were investigated in various solvents together with an evaluation of the efficiency of these copolymers as pour point depressants for two different samples of crude oil. EVA copolymers containing 20, 30, 40 and 80 wt.% of vinyl acetate were used and tests with the crude oil were carried out using 50, 500, 1000 and 5000 ppm of EVA as additive. The results obtained from viscosity measurements showed that only below the temperature at which wax crystals start forming did the copolymer exhibit a strong influence in the reduction of oil viscosity, at an optimum concentration. The pour point results revealed EVA 30 to be the most efficient. The results obtained from both experiments showed that the viscosity and the pour point behaviors do not show good correlation. Not only the solubility parameter and the vinyl acetate content, but also the molecular weight and polydispersity have an important influence on both phase behavior and pour point depression. Furthermore, it was confirmed that the additive must present a reduced solubility at a temperature close to the crude oil cloud point. This, however, is not the only factor that determines the efficiency of the additive as paraffin

    Many SLC26A4 mutations have been identified in patients with nonsyndromic enlarged vestibular aqueduct (EVA). However, the roles of SLC26A4 genotypes and phenotypes in hereditary deafness remain unexplained. This study aims to perform a meta-analysis based on the PRISMA statement to evaluate the diagnostic value of SLC26A4 mutant alleles and their correlations with multiethnic hearing phenotypes in EVA patients. The systematic literature search of the PubMed, Wiley Online Library, EMBASE, Web of Science, and Science Direct databases was conducted in English for articles published before July 15, 2015. Two investigators independently reviewed retrieved literature and evaluated eligibility. Discrepancy was resolved by discussion and a third investigator. Quality of included studies was evaluated using Newcastle-Ottawa Quality Assessment Scale. Data were synthesized using random-effect or fixed-effect models. The effect sizes were estimated by measuring odds ratios (ORs) with 95% confidence interval (CI). Twenty-five eligible studies involved 2294 cases with EVA data. A total of 272 SLC26A4 variations were found in deafness with EVA and 26 mutations of SCL26A4 had higher frequency. The overall OR was 646.71 (95% CI: 383.30-1091.15, P = 0.000). A total of 22 mutants were considered statistically significant in all ethnicities (ORs >1, P deafness populations (ORs >1, P 1, P G mutations in SLC26A4 were found to have the highest frequency in deafness individuals with EVA phenotype (62.42%). Moreover, subgroups for studies limited to cases with EVA phenotype, 11 mutants relevant risks (RRs) were P G bi-allelic mutants assayed in a deafness population (RR = 0.880, P = 0.000). Diagnostic accuracy of SLC26A4 mutation results also identified the significant association of IVS7-2A>G (AUC = 0.99, 95% CI: 0.97-0.99) and p.H723R (AUC = 0.99, 95% CI: 0.98-1.00) detecting deafness with EVA. To conclude, the IVS7-2A>G and H723R in SLC26A4 present a

    Nowadays, a lot of solid waste material is discarded into the environment. One of these residues is the EVA (Ethyl Vinyl Acetate) which has the footwear industry, as its main consumer. Studies are focused on the reusing of these materials, particularly in the civil construction, where is used as an aggregate in the production of light mortars. Due to the specific characteristics of lightweight concrete, is necessary to reinforce these materials. The palm Attalea Funifera Martius, known as piacava, may be an excellent alternative as a reinforcement element in light cement mixes. In this work, it's verified the mechanical strength of a composite lightweight cementitious with EVA and reinforced with Piacava fibers, also, the porosity of the new material was measured. To evaluate the mechanical properties of this new material was made mechanical tests and verified the importance of vegetal fibers as the material reinforcing. For the compound porosity evaluation, samples were studied using microcomputer tomography (μTC). With images processing techniques we identify and quantify the pores. The processing digital images through μTC showed up as a non-destructive method for efficient and acceptable results. (author)

    Full Text Available Eva Boesenberg setzt sich aus einer kultur- und literaturhistorischen Perspektive mit der Verknüpfung von Ökonomie und Geschlechterdiskurs im US-amerikanischen Roman auseinander. Im Zentrum steht die Frage, ob und zu welchem Grad die ‚Sprache des Geldes‘ geschlechtsspezifisch codiert ist und welche Besonderheiten gerade im nordamerikanischen Kulturraum zu beobachten sind. Die Autorin behandelt die literarische Repräsentation dieses Geflechts in insgesamt 35 Romanen aus der Zeit von 1850 bis 2000, wobei ihr Fokus auf den geschlechtsökonomischen Relationen liegt, die weniger hierarchisch angelegt seien als hegemoniale Konstruktionen, und liefert zugleich einen kenntnisreichen geschichtlichen Abriss über den Zusammenhang von Geschlecht und Wirtschaft.From a cultural and literary historic perspective, Eva Boesenberg deals with the correlation of economy and gender discourse in the American novel. At the center of the discussion is the question whether and to what degree the ‘language of money’ is gender-specifically coded and which peculiarities can be seen particularly in the North-American cultural sphere. With a focus on gender-economic relations, which are less hierarchic than hegemonic constructions, the author analyzes the representation of this network in a total of thirty-five novels from 1850 to 2000. Furthermore, she also offers a knowledgeable historical overview on the relation of gender and economy.

    Full Text Available Increase in the value for the key stakeholders, i.e. shareholders, is one of the most important goals of a modern corporation. A new concept based on the value, so-called, Economic Value Added - EVA is a derived internal measure of value creation that helps managers in their decision-making processes which incorporate two basic principles of finance: the maximization of shareholders' wealth and that the value of the company depends on investor expectations that the future profits will exceed the cost of the capital. EVA is directly related to the external performance of the company in the capital market, i.e. Market Value Added - MVA. MVA is the assessment of the capital markets, within a specified period of time and reflects the success with which the company invested capital in the past and expectations of the success of performance of investing capital in the future, which affects the value of the company, and thus a shareholder value, as well.

    A lifetime of 20-30 years is generally regarded as necessary for photovoltaic modules to achieve economic break even. As a consequence, understanding how to improve the durability and reliability of the modules is becoming a necessity. Photovoltaic modules are exposed to extremely harsh conditions of heat, humidity, and ultraviolet (UV) radiation which affect the properties of the encapsulant material and cause yellowing, delamination and degradation of the material, which knock on effects on the performance and the long-term reliability of photovoltaic modules. This study addresses the impact of UV on the photochemical degradation of Ethylene-vinyl Acetate (EVA). Fourier Transform Infrared Spectroscopy in Attenuated Total Reflectance (FTIR-ATR) mode was performed on aged samples. The samples were exposed to UV light from a xenon lamp at 0.68 W/m2 at 340 nm with exposure up to 1000 hours. The FTIR-ATR measurement shows significant changes in the absorption at 1740 cm-1, 1720 cm-1 and 910 cm-1 which correspond to acetate, carboxylic acid and vinyl group respectively. It is shown that the UV exposure is the most significant aging factor. The rate of the photooxidation of EVA is compared by measuring the changes of absorbance at 1720 cm-1 with the UV irradiation time.

    Full Text Available Despite its ongoing popularity with women readers, romantic fiction has traditionally been regarded as an instrument of women's oppression, largely due to its reinforcement and even glorification of sexual stereotypes and bourgeois values. Latin American writer Isabel Allende's novels The House of the Spirits and Eva Luna both contain a number of the elements and conventions of romantic fiction, including distinct similarities to the two acknowledged foundations of this genre: Charlotte Brontë's Jane Eyre and Emily Brontë's Wuthering Heights.However, The House of the Spirits and Eva Luna can also be read as rewritings of the genre of romantic fiction. In these two texts, Isabel Allende appropriates and then reworks certain conventions of romantic fiction in order to portray her notion of "fulfilling egalitarian relationships" between men and women. Nevertheless, despite these feminist revisions, Allende's rewritten romances do retain the "wish-fulfillment" element-or ideal-of romantic fiction, its depiction of women's fantasy of feminine values being appreciated and validated within heterosexual romantic relationships in the real world.

A adoção da perspectiva da sociologia da crítica de Boltanski, em associação com aportes pontuais de Bourdieu, Wolf e Elias, permitiu compreender os processos de mobilidade e de construção da coesão social dos assentados. Essa última é relacionada à reciprocidade, em especial ao parentesco e às relações religiosas e de vizinhança. Verificou-se que os assentados, cada vez mais situados na "cidade doméstica", estão construindo processos corporativos, ainda que de forma negociada com o MST, INCRA e vizinhança. Não se encontrou correlação entre a evasão e diversas variáveis relacionadas à dimensão material nos 193 assentamentos pesquisados.

    The compounding of complete total parenteral nutrition (TPN) mixtures into big bags with extended shelf-lives has been made more possible by the introduction of reduced gas permeable bags, using multi-layered plastic laminates. Since this produces a highly reduced chemical environment, the stability of thiamine; which degrades by reduction, may be compromised. It was the purpose of this study to investigate the degradation of thiamine at two different concentrations in TPN mixtures containing different commercial amino acid sources stored for extended periods in EVA or multi-layered bags. Results indicated that thiamine was unstable in mixtures containing Freamine III 8.5%, a metabisulphite-containing amino acid infusion, but was relatively stable in mixtures containing Vamin 14, Aminoplex 12 or Eloamin 15% as the amino acid source. Degradation of thiamine in Freamine III 8.5%-containing mixtures stored in multi-layered bags was more rapid than in EVA bags. Degradation rate was not greatly influenced by thiamine concentration. Results indicate that thiamine is stable in complete TPN mixtures for periods of at least 28 days in multi-layered bags, provided metabisulphite containing amino acid infusions are avoided. The shelf-life of complete mixtures containing Freamine III should be restricted to ensure patient receive minimum acceptable daily thiamine requirements.

    Full Text Available In this research, the effects of chemical foaming agent and wood flour content on cell morphology, density and mechanical properties of HDPE/EVA/ Wood Flour hybrid foamed composites were investigated. For this aim, composites were prepared via melt mixing in an internal mixer, then foamed using single-stage batch foaming method. Then mechanical properties such as flexural strength, flexural and tensile modulus and density were measured. Morphology of the samples was also evaluated by scanning electron microscopy (SEM. The results of this study have indicated that the flexural strength, flexural and tensile modulus and density increases with the increase of wood flour content. However, with addition of chemical foaming agent content and EVA content, mechanical properties and density of foamed composites decreased. Moreover, wood fiber acted as nucleating agents that substantially reduced cell size and increased cell density. In addition, EVA plays an important role in foaming process by increasing the melt viscosity of the polymer matrix, in a way that samples with higher content of EVA have the highest cell density and the lowest cell size.

  14. The expression pattern of EVA1C, a novel Slit receptor, is consistent with an axon guidance role in the mouse nervous system.

    Directory of Open Access Journals (Sweden)

    Gregory James

    Full Text Available The Slit/Robo axon guidance families play a vital role in the formation of neural circuitry within select regions of the developing mouse nervous system. Typically Slits signal through the Robo receptors, however they also have Robo-independent functions. The novel Slit receptor Eva-1, recently discovered in C. elegans, and the human orthologue of which is located in the Down syndrome critical region on chromosome 21, could account for some of these Robo independent functions as well as provide selectivity to Robo-mediated axon responses to Slit. Here we investigate the expression of the mammalian orthologue EVA1C in regions of the developing mouse nervous system which have been shown to exhibit Robo-dependent and -independent responses to Slit. We report that EVA1C is expressed by axons contributing to commissures, tracts and nerve pathways of the developing spinal cord and forebrain. Furthermore it is expressed by axons that display both Robo-dependent and -independent functions of Slit, supporting a role for EVA1C in Slit/Robo mediated neural circuit formation in the developing nervous system.

    Nowadays, a great attention has been dedicated to natural fibers as reinforcement for polymer composites. Natural fibers, compared to glass fibers, exhibit better mechanical properties, such as stiffness, impact strength, flexibility and modulus. However, certain drawbacks, such as the incompatibility between fibers and polymer matrices, the tendency to form aggregates during processing and the poor resistance to moisture, reduce the use of these natural fibers as reinforcements in polymers. Several treatments and modifications are being used to improve the adhesion between fibre and matrix. In this work, the effect of bleaching treatments using hydrogen peroxide in the Mengkuang leaf fibre (MLF) was evaluated on tensile properties of Ethylene Vinyl Acetate (EVA)/Natural Rubber (NR)/MLF composites. Treated MLF were mixed with the EVA/NR blend in Haake internal mixer at 120 °C and rotor speed of 50 rpm for 10 minutes. Fibre morphology and the fibre/matrix interface ware further characterized by scanning electron microscopy (SEM). The tensile strength was increased by about 8% as compared to the composites with untreated fibers. The increased adhesion between fiber and matrix was also observed by SEM. Thus, EVA/NR/MLF composites reinforced with the treated fibres exhibited better tensile properties than untreated EVA/NR/MLF composites.

    Polymer-clay based nanocomposites are among the attractive materials to be applied for various applications, including biomedical. The incorporation of the nano sized clay (nanoclay) into polymer matrices can result in their remarkable improvement in mechanical, thermal and barrier properties as long as the nanofillers are well exfoliated and dispersed throughout the matrix. In this work, exfoliation strategy through pre-dispersing process of the organically modified montmorillonite (organo-MMT) nanofiller was done to obtain ethyl vinyl acetate (EVA) nanocomposite with improved flexibility, toughness, thermal stability and biostability. Our results indicated that the degree of organo-MMT exfoliation affects its cytotoxicity level and the properties of the resulting EVA nanocomposite. The pre-dispersed organo-MMT by ultrasonication in water possesses higher degree of exfoliation as compared to its origin condition and significantly performed reduced cytotoxicity level. Beneficially, this nanofiller also enhanced the EVA flexibility, thermal stability and biostability upon the in vitro exposure. We postulated that these were due to plasticizing effect and enhanced EVA-nanofiller interactions contributing to more stable chemical bonds in the main copolymer chains. Improvement in copolymer flexibility is beneficial for close contact with human soft tissue, while enhancement in toughness and biostability is crucial to extend its life expectancy as insulation material for implantable device.

    Full Text Available Este trabalho mensura o impacto das alíquotas do imposto de importação sobre a evasão fiscal nas importações brasileiras oriundas dos Estados Unidos. Os resultados obtidos permitem concluir que as alíquotas tarifárias influenciam a evasão sob suas diferentes formas: subfaturamento e classificação incorreta de mercadorias. Estes resultados corroboram o modelo básico de evasão proposto por Allingham (1972 e se insere no debate sobre a relação entre a magnitude das alíquotas e o potencial para evasão. Nossos resultados mostram, ainda, a existência de não linearidades na relação entre alíquotas e evasão. Nos vários modelos testados, esse efeito cresce com a magnitude das tarifas, sugerindo que maiores alíquotas aumentam o custo de oportunidade da tributação e geram maiores incentivos para a sonegação. Por fim, com respeito à relação entre o nível de complexidade da estrutura tributária e a evasão, nosso trabalho sugere que uma maior diferenciação entre alíquotas, dificulta a administração tarifária e pode levar a evasão.In this paper we measure the effect of tax rates on tax evasion using data on the trade flow between Brazil and the United States. Our results show that increases in the tax rates lead to higher evasion on two different ways: under invoicing and mislabeling higher taxed products as lower ones. These results corroborate the theoretical predictions of the Allingham (1972 model and contribute to the recent debate on the influence of tax rates on evasion. We also point out to the existence of nonlinearities in the relationship between tax rates and evasion by showing that higher rates raise the opportunity costs of paying taxes and thus encourage evasion. Finally, our results suggest that relatively high rates and a complex set of rules, especially for customs taxes, result in large potential rewards for taxpayers willing to bribe to cut their own tax burden and/or speed up customs clearance of

    We have developed an integrated health impact assessment system EVA (Economic Valuation of Air pollution; Brandt et al., 2013a; 2013b), based on the impact-pathway chain, to assess the health impacts and health-related economic externalities of air pollution resulting from specific emission sources or sectors. The system is used to support policymaking with respect to emission control. The EVA system has previously been used to assess the health impacts based on results from a regional model DEHM (the Danish Eulerian Hemispheric Model; Brandt et al., 2012). In this study we have used a coupling of two chemistry transport models to calculate the air pollution concentration at different scales; the DEHM model to calculate the air pollution levels with a resolution down to 5.6 km x 5.6 km and the UBM model (Urban Background Model ; Berkowicz, 2000; Brandt et al., 2001) to further calculate the air pollution at 1 km x 1 km resolution for Denmark using results from DEHM as boundary conditions. Both the emission data based on the SPREAD model (Plejdrup and Gyldenkærne, 2011) as well as the population density has been represented in the model system with the same high resolution. The new developments of the integrated model system will be presented as well as results for health impacts and related external costs over the years 2006-2014 for Denmark. Furthermore, a sensitivity study of the health impact using coarse and fine resolutions in the model system has been carried out to evaluate the effect of improved description of the geographical population distribution with respect to location of local emissions.

    Full Text Available Financial distress prediction plays an important role in the survival of companies. In this paper, a novel biorthogonal wavelet hybrid kernel function is constructed by combining linear kernel function with biorthogonal wavelet kernel function. Besides, a new feature weighted approach is presented based on economic value added (EVA and grey relational analysis (GRA. Considering the imbalance between financially distressed companies and normal ones, the feature weighted one-class support vector machine based on biorthogonal wavelet hybrid kernel (BWH-FWOCSVM is further put forward for financial distress prediction. The empirical study with real data from the listed companies on Growth Enterprise Market (GEM in China shows that the proposed approach has good performance.

  4. Characterization of Thermo-Physical Properties of EVA/ATH: Application to Gasification Experiments and Pyrolysis Modeling

    Full Text Available The pyrolysis of solid polymeric materials is a complex process that involves both chemical and physical phenomena such as phase transitions, chemical reactions, heat transfer, and mass transport of gaseous components. For modeling purposes, it is important to characterize and to quantify the properties driving those phenomena, especially in the case of flame-retarded materials. In this study, protocols have been developed to characterize the thermal conductivity and the heat capacity of an ethylene-vinyl acetate copolymer (EVA flame retarded with aluminum tri-hydroxide (ATH. These properties were measured for the various species identified across the decomposition of the material. Namely, the thermal conductivity was found to decrease as a function of temperature before decomposition whereas the ceramic residue obtained after the decomposition at the steady state exhibits a thermal conductivity as low as 0.2 W/m/K. The heat capacity of the material was also investigated using both isothermal modulated Differential Scanning Calorimetry (DSC and the standard method (ASTM E1269. It was shown that the final residue exhibits a similar behavior to alumina, which is consistent with the decomposition pathway of EVA/ATH. Besides, the two experimental approaches give similar results over the whole range of temperatures. Moreover, the optical properties before decomposition and the heat capacity of the decomposition gases were also analyzed. Those properties were then used as input data for a pyrolysis model in order to predict gasification experiments. Mass losses of gasification experiments were well predicted, thus validating the characterization of the thermo-physical properties of the material.

    A new energetic thermoplastic elastomer based on the azidated polybutadiene(Az-PBD)/ethylene vinyl acetate copolymer (EVA) blends was prepared, and structure and properties of the blends were investigated by SEM, DSC, DMA, tensile testing and combustion test. The Az-PBD was synthesized via a two-step process involving the addition reaction of commercially available 1,2-PBD with Br{sub 2} and subsequent nucleophilic substitution reaction of the brominated PBD with NaN{sub 3}. EVA/Az-PBD with 90/10, 80/20, 70/30 (wt/wt) was prepared by a solution blending. SEM, DSC, and DMA results revealed that the blends are partially compatible and Az-PBD is dispersed in continuous EVA matrix. Tensile test showed that modulus and tension set increased while elongation-at-break of the blends decreased with increasing Az-PBD content in the blends, but all the blends showed a elongation at break as high as 700% and a tension set of less than 5%, indicating that the blends are typically elastomeric. Combustion test showed that, with increasing Az-PBD content in the blend, higher energy can be released.

    2018-01-01

    This study is focused on the radiooxidative degradation of polymeric insulation of electric cables used in Nuclear Power Plants (NPPs). In order to investigate the degradation mechanisms of the insulation, model composites with ATH (Aluminium TriHydrate) filler and blends (without filler) based on a cross-linked mixture of EVA (Ethylene Vinyl Acetate) and EPDM (Ethylene Propylene Diene Monomer) were submitted to gamma-rays. In normal operating conditions of a NPP, the dose rate which electric cables are exposed to is around 0.1 Gy h-1. In this work, artificial accelerated ageing test process has been applied at a relatively low dose rate of 7 Gy h-1. Gamma-irradiations at higher dose rates typically used to accelerate the ageing, in the range 0.2-1 kGy h-1, were also carried out. The first part of the study is focused on irradiations performed at relatively low dose rate and is devoted to the highlighting of the radiooxidative degradation mechanisms of EVA/EPDM blend with and without ATH filler. Correlations between the evolutions of the chemical, morphological and mechanical/electrical properties of the materials occurring after the ageing process are presented. It is shown that the degradation process is governed by radical oxidation mechanism involving chain scissions leading to the formation of carboxylic acids as end-groups. One of the main effects of the ATH filler is the progressive loss of the mechanical properties of the composite upon radiooxidation whereas they are maintained in the case of the unfilled sample. Despite the oxidation of the polymer, no change in the electrical properties of the blend and of the composite could be observed. The second part of the study focuses on the dose rate effect. It is shown that one of the main consequences of an increase of the dose rate from 7 Gy h-1 to 0.2-1 kGy h-1 is a reduction of the chain scission process yield by a factor of about 20. Therefore, an important and consistent finding is that there are some

    Full Text Available Recentes iniciativas do Governo Federal como o PROUNI (Programa Universidade para Todos e o FIES (Fundo de Financiamento Estudantil têm subsidiado o ingresso de estudantes em Instituições de Ensino Superior Privadas. Esta política diminui a motivação financeira que poderia gerar evasão. Mesmo tendo sido criado em 2005, os bolsistas destes programas representam entre 7 e 8% do total de ingressantes em instituições privadas (dados divulgados em 2012 pelo INEP e PROUNI. Deste modo, tendo em grande parte sua receita advinda de alunos pagantes, as instituições privadas têm que gerenciar elementos que afetam sua viabilidade econômica tal como ocorre com a evasão. Ao ajustarem seus recursos frente à evasão poderia haver redução na qualidade do ensino ofertado. O objetivo deste estudo foi verificar a relação entre a evasão discente e a qualidade da educação oferecida no ensino superior privado. Na hipótese baseada na Economia dos Custos de Transação (ECT argumentou-se que instituições de ensino superior privadas poderiam reduzir sua qualidade devido à evasão como ajuste de eficiência. O indicador de qualidade IGC (Índice Geral de Cursos utilizado pelo MEC, foi regredido em função da evasão. Os resultados suportaram a existência de uma relação linear negativa entre qualidade ofertada e evasão. Esta relação ilustra os riscos de se expandir a oferta do ensino superior com qualidade por meio do aumento indiscriminado de vagas em instituições privadas.

    Full Text Available The history of printing and book publication in Bjelovar-Bilogorje District has not been sufficiently studied and evaluated. The few published papers on this topic represent only a scant review of the matter and provide no explanation as to the role of the periodicals, in particular journals and newspapers, in the overall development of the town of Bjelovar and the District. It strikes one as particularly odd how little writing has been devoted to the first Bjelovar weekly newspaper, Tjednik bjelovarsko-križevački. Our paper is an overview of the facts on the beginning of its publication, the makeup of the editorial board and the editors in chief, the contents, genres, columns, circulation, distribution, popularisation and layout. The range of topics covered, the overall atmosphere and the wide scope of the social life covered by the newspaper shed light on its influence on the development of literacy and the culture of reading, and on its role in the cultural, educational and political life of the town and the region in the late 19th and early 20th century. A special reason for writing this text resides in the fact that in the absence of other source material Tjednik bjelovarsko-križevački is an important tool in the study of the local history. The chief study sources were the complete annual editions of Tjednik stored in the National University Library. Bibliographic sources and material were consulted regarding the development of printing and the publication of periodicals. The theoretical starting points were found in the works of Josip Horvat, Božidar Novak, Srećko Lipovčan, Ivanka Kuić, Ivo Perić, Vjekoslav Maštrović and others. The paper utilises the historic and comparative methods, and the methods of compilation, description, analysis and synthesis. The first regionally distributed weeklies were commonly published by local printers with businesses set up in the district centres. An enormous breakthrough in the development of

    2016-03-01

    Full Text Available Consideration of Spain in a chronological advance with a closer history or a history of major disagreements depending on circumstances reproduces the indelible mark of conquest and survives a need to justify the mention of Spain or the incorporation of Spanish names in these latitudes to account for that which is being taken into consideration is somewhere different and presents a break point before any possibility of monolithic Hispanic identity. A timeline with strong milestones about imperialism seems to prevent the trial from any other experience of temporality. Now, what happens when a new approach is given from the appropriation which is a significant time shift, accompanied by a spatial gap, and also a distortion of those aspects of Spain that seem to move chronologically flush with the context from which it brings to mind? The detail that will be held in the stories “El orden de todas las cosas” and “Sueño con medusas”, by Bruzzone, and in Diario de una Princesa Montonera, by Mariana Eva Perez, considers two narrative experiences that are disruptively linked to Spain, wrecking with a kind of accompaniment addressed chronologically and indicted, to lead, however, a relationship over time which shows signs of a memory exercise well away from the idea of linear progression and any semblance of continuity.

    2009-01-01

    There are currently several physiological monitoring requirements for EVA in the Human-Systems Interface Requirements (HSIR) document. There are questions as to whether the capability to monitor heart rhythm in the lunar surface space suit is a necessary capability for lunar surface operations. Similarly, there are questions as to whether the capability to monitor heart rhythm during a cabin depressurization scenario in the launch/landing space suit is necessary. This presentation seeks to inform space medicine personnel of recommendations made by an expert panel of cardiovascular medicine specialists regarding in-suit ECG heart rhythm monitoring requirements during lunar surface operations. After a review of demographic information and clinical cases and panel discussion, the panel recommended that ECG monitoring capability as a clinical tool was not essential in the lunar space suit; ECG monitoring was not essential in the launch/landing space suit for contingency scenarios; the current hear rate monitoring capability requirement for both launch/landing and lunar space suits should be maintained; lunar vehicles should be required to have ECG monitoring capability with a minimum of 5-lead ECG for IVA medical assessments; and, exercise stress testing for astronaut selection and retention should be changed from the current 85% maximum heart rate limit to maximal, exhaustive 'symptom-limited' testing to maximize diagnostic utility as a screening tool for evaluating the functional capacity of astronauts and their cardiovascular health.

    To determine whether systemic oxidative stress status is associated with cognitive decline. A longitudinal population-based study. A cohort study of older subjects in Nantes, France. A total of 1166 high cognitive functioning subjects aged 60 to 70 in the Etude du Vieillissement Arteriel (EVA) cohort with a 4 year follow-up. Subjects completed a baseline interview and a global cognitive test (Mini-Mental Status Examination (MMSE)). Blood samples were obtained at baseline to determine plasma levels of selenium, carotenoids, thiobarbituric acid reactant substances (TBARS), an indicator of lipoperoxidation, and red blood cell vitamin E. Risk of cognitive decline, defined as a loss of 3 points in MMSE score between baseline and the 4 year follow-up, was assessed by oxidative stress level. Subjects with the highest levels of TBARS show an increased risk of cognitive decline (adjusted odds ratio (OR) = 2.25; confidence interval (CI) 95% = 1.26-4.02). This result is reinforced in the lower antioxidant status subgroup. Subjects with low levels of selenium have an increased risk of cognitive decline (OR = 1.58; CI 95% = 1.08-2.31) after adjustment for various confounding factors. These results suggest that increased levels of oxidative stress and/or antioxidant deficiencies may pose risk factors for cognitive decline. The direct implication of oxidative stress in vascular and neurodegenerative mechanisms that lead to cognitive impairment should be further explored.

    Bernardo Fonseca Tutikian

    Full Text Available Resumo O copolímero etileno acetato de vinila (EVA é largamente utilizado na indústria calçadista. Entretanto, a geração de resíduos no processo de fabricação é bastante significativa. Com a implementação da norma de desempenho, NBR 15575, os projetos de construções habitacionais devem atender aos níveis de desempenho exigidos. Dentre os requisitos prescritos pela norma está a isolação ao ruído de impacto entre pisos, a qual pode ser otimizada com a utilização de materiais de baixa massa específica. Nesse contexto, este artigo visa desenvolver uma argamassa leve, a partir da incorporação de EVA proveniente da indústria calçadista, a ser utilizada como contrapiso para isolamento acústico. Para tanto, fez-se um estudo por meio de ensaios de resistência à compressão e à tração, bem como nível de pressão sonora de impacto padronizado ponderado, realizado em câmara normatizada. Foram desenvolvidos cinco traços, com proporções de 20%, 40%, 60%, 80% e 100% de substituição da agregado miúdo por EVA, além do contrapiso convencional. Foram moldadas placas de 1 m2 de contrapiso leve, e uma amostra representativa do tamanho da laje com 16 m2, as quais diferiram em 2 dB para o isolamento acústico. O traço com melhor desempenho proporcionou uma redução de 9 dB em relação ao contrapiso convencional, mostrando ser eficaz para utilização como isolante acústico.

    Full Text Available Eva Rossmann’s mystery novel Russen kommen, the tenth in a popular series, takes up a hot topic in Austria’s tourism industry: the tensions surrounding the recent influx of newly rich Russian visitors. This article uses Rossmann’s mystery as a case study to examine the impact of global culture and transnational investments on Austrian society. Trapped between provincialism and globalization, Austrians are forced to revisit old fears and find new ways of dealing with contemporary challenges. Due to its wide appeal, popular culture can lead the way in these negotiations.

    Full Text Available Este artigo aborda uma pesquisa sobre os fatores associados à evasão de estudante com deficiência na educação profissional técnica de nível médio, bem como fatores que contribuem para a sua permanência e certificação. Para examinar a evasão escolar desses sujeitos, foi realizada uma análise descritiva de questionários aplicados a alunos evadidos das escolas técnicas federais de Minas Gerais, no período de 2007 a 2010, bem como dos dados do Censo Escolar do INEP sobre as escolas técnicas federais em Minas Gerais. Os resultados mostram que os fatores associados ao abandono escolar de alunos com deficiência apresentam aspectos similares aos dos alunos evadidos em geral. Abrangem, por exemplo, a dificuldade de conciliar estudo e trabalho. Há, contudo, aspectos que dizem respeito apenas aos alunos com deficiência, tais como a acessibilidade, a ausência do atendimento educacional especializado, inclusive domiciliar e hospitalar. Os estudos nos dados do censo escolar de 2007 a 2010 assinalam também avanços em direção à organização de uma rede federal de educação técnica inclusiva em Minas Gerais.

    Functional Extravehicular Mobility Units (EMUs) with high precision gloves are essential for the success of Extravehicular Activity (EVA). Previous research done at NASA has shown that total strength capabilities and performance are reduced when wearing a pressurized EMU. The goal of this project was to characterize the human-space suit glove interaction and assess the risk of injury during common EVA hand manipulation tasks, including pushing, pinching and gripping objects. A custom third generation sensor garment was designed to incorporate a combination of sensors, including force sensitive resistors, strain gauge sensors, and shear force sensors. The combination of sensors was used to measure the forces acting on the finger nails, finger pads, finger tips, as well as the knuckle joints. In addition to measuring the forces, data was collected on the temperature, humidity, skin conductance, and blood perfusion of the hands. Testing compared both the Phase VI and Series 4000 glove against an ungloved condition. The ungloved test was performed wearing the sensor garment only. The project outcomes identified critical landmarks that experienced higher workloads and are more likely to suffer injuries. These critical landmarks varied as a function of space suit glove and task performed. The results showed that less forces were acting on the hands while wearing the Phase VI glove as compared to wearing the Series 4000 glove. Based on our findings, the engineering division can utilize these methods for optimizing the current space suit glove and designing next generation gloves to prevent injuries and optimize hand mobility and comfort.

    Full Text Available Espumas poliméricas são materiais bifásicos constituídos por uma matriz polimérica sólida e por uma fase gasosa proveniente de um agente de expansão. Produtos obtidos com estes materiais vêm ganhando bastante espaço no mercado por apresentar boas propriedades mecânicas aliadas à baixa densidade e baixo custo. O uso de EVA com elastômeros tem sido uma alternativa para proporcionar propriedades mais nobres a esses compostos expansíveis. Dentre os elastômeros utilizados, o EPDM apresenta um potencial de aplicação elevado por apresentar boa compatibilidade com as poliolefinas. Como na fabricação da espuma tem-se simultaneamente reações de reticulação e de formação gases de expansão, o balanço desses efeitos tem forte influência sobre as características físicas do produto. Neste estudo, avaliou-se o efeito de um agente reticulante nas formulações de espumas de EVA/EPDM. As propriedades físico-mecânicas, reométricas e morfológicas de misturas EVA/EPDM com diversas proporções de peróxido de dicumila, utilizado como agente de reticulação, foram avaliadas. Os resultados mostraram que o teor de reticulante apresenta forte influência nas características técnicas das espumas obtidas.Polymer foams are biphasic materials prepared with a polymer matrix and a gaseous phase from a foaming agent. Products based on this type of material are currently in a good market position due to the good mechanical properties, low density and competitive cost. Blending EVA with elastomers is a feasible alternative to enhance the properties of the expandable compounds. Among the elastomers used as a blend component with EVA, EPDM has a high potential since it has a good compatibility with polyolefins. Considering that during the foam processing there are simultaneous crosslinking reactions and the formation of gases, the balance between these two effects has a strong influence over the physical characteristics of the final product.

    We have developed an integrated model system, EVA (Economic Valuation of Air pollution), based on the impact-pathway chain, to assess the health-related economic externalities of air pollution resulting from specific emission sources or sectors, which can be used to support policy-making with respect to emission control. Central for the system is a tagging method capable of calculating the contribution from a specific emission source or sector to the overall air pollution levels, taking into account the non-linear atmospheric chemistry. The main objective of this work is to identify the anthropogenic emission sources in Europe and Denmark that contribute the most to human health impacts. In this study, we applied the EVA system to Europe and Denmark, with a detailed analysis of health-related external costs from the ten major emission sectors and their relative contributions. The paper contains a thorough description of the EVA system. The conclusions in the paper are sensitive to the toxicity of the different types of atmospheric particles, and therefore the existing knowledge of health impacts from particles is reviewed. We conclude that with our present knowledge we are not able to distinguish between the impacts from different particle types and therefore the toxicity of the particles is handled equally in the overall results. The main conclusion from the analysis of the ten major emission sectors in Europe and Denmark is that the major contributors to health-related external costs are major power production, agriculture, road traffic, and non-industrial domestic combustion, including wood combustion. The major power plants in Europe contribute with around 25% of the total health related external costs relative to all sources in Europe, while the Danish power plants only contribute with less than 10% relative to all Danish sources. Our results suggest that the agricultural sector contributes with 25% to health impacts and related external costs. We conclude

    A high-resolution assessment of health impacts from air pollution and related external cost has been conducted for Denmark using the integrated EVA model system. The EVA system is based on the impact-pathway methodology, where the site-specific emissions will result, via atmospheric transport and chemistry, in a concentration distribution, which together with detailed population data, is used to estimate the population-level exposure. Using exposure-response functions and economic valuations, the exposure is transformed into impacts on human health and related external costs. In this study we have used a coupling of two chemistry transport models to calculate the air pollution concentration at different domain and scales; the Danish Eulerian Hemispheric Model (DEHM) to calculate the air pollution levels in the Northern Hemisphere with a resolution down to 5.6 km x 5.6 km and the Urban Background Model (UBM) to further calculate the air pollution in Denmark at 1 km x 1 km resolution using results from DEHM as boundary conditions. Both the emission data as well as the population density has been represented in the model system with the same high resolution. Previous health impact assessments related to air pollution have been made on a lower resolution. In this study, the integrated model system, EVA, has been used to estimate the health impacts and related external cost for Denmark at a 1 km x 1 km resolution. New developments of the integrated model system will be presented as well as the development of health impacts and related external costs in Europe and Denmark over a period of 36 years (1979-2014).

    process and the test director kept track of the timeline in verbal cues to the crewmember. At the conclusion, the team member conducting the scientific study appraised the samples and train of thought. Test C was a 90-minute EVA simulation using two crewmembers working out of line-of-sight in communication with a science backroom. The science objectives were determined by the science backroom team in advance using a Gigapan image of the outcrop (Fig. 1). The science team formulated hypotheses for the outcrop units and created sampling objectives for impact-melt lithologies; the science team turned these into a science plan, which they communicated to the crew in camp prior to crew deployment. As part of the science plan, the science team also discussed their sample needs in depth with the crewmembers, including laboratory methods, objectives, and samples sizes needed. During the deployment, the two crewmembers relayed real-time information to the science backroom by radio with no time delay. Both the crew and science team re-evaluated their hypotheses and science plans in real-time. Discussion: Upon evaluation, we found that the focused tests (Tests A and B) were successful in meeting their scientific objectives. The crewmember used their knowledge of how the samples were to be used in further study (technique, sample size, and scientific need) to focus on the sampling task. The crewmember was comfortable spending minimal time describing and mapping the outcrop. The crewmember used all available time to get a good sample. The larger test was unsuccessful in meeting the sampling objectives. When the crewmembers began describing the lithologies, it was quickly apparent that the lithologies were not as the backroom expected and had communicated to the crew. When the outcrop wasn't as expected, the crew members instinctively switched to field characterization mode, taking significant time to characterize and map the outcrop. One crew member admitted that he "kind of lost

  5. Breaking the Gender Binary: Feminism and Transgressive Female Desire in Lucía Etxebarria's Beatriz y los cuerpos celestes and La Eva futura/La letra futura

    Directory of Open Access Journals (Sweden)

    Lauren Applegate

    2013-06-01

    Full Text Available The popular texts of Spanish author Lucía Etxebarria have created a polemical social phenomenon in contemporary Spain for their blatant depiction of a world of violence, drugs, and experimental sex of the late-millennium youth culture of Generación X. These topics, along with Etxebarria's public persona and feminist ideology, have fomented much public criticism and given rise to discussion of the current status of feminism, gender norms, and women's authorship in Spain today. This article analyzes Etxebarria's novel Beatriz y los cuerpos celestes and her collection of feminist essays La Eva futura/La letra futura, demonstrating that Etxebarria's depiction of female desire and sexuality within their cultural context challenges the notion that feminism has no more to achieve and breaks the gender binary by imagining a gender-anonymous world. Beatriz delves into the life of the title character, a young woman whose experience with a dissolute social culture and her attempts to understand herself cause her to question stereotypical standards of womanhood and eroticism and to declare that she fits into no such preconceived notions. Beatriz is a literary inscription of Etxebarria's feminist ideology as posited in La Eva futura, insofar as both these texts blur the line between feminism and postfeminism and engage with consumerist culture and identity. Moreover, they construe a philosophy that pushes the boundaries of normative discourse by misciting hegemonic notions of femininity and sexuality and creating the potential for change through such mis-repetition of hegemonic discourse. Ultimately, Etxebarria's work strives for a transgressive, unbound, and fluid female desire that is in continuous reconstruction and defies heteronormative definition.

    Selenium (Se) and antioxidant vitamins might play an important role in the etiology of free radical-related diseases and aging. In the Edude de vieillissement artériel (EVA) study, we have determined the plasma thiobarbituric acid reacting substances (TBARS) as an indicator of free radical-induced lipid peroxidation, plasma selenium and carotenoids, and erythrocyte vitamin E levels in 1389 subjects aged 59-71 years. We also looked for an association between these parameters and cardiovascular risk factors in early elderly. The results show that plasma TBARS were significantly increased in elderly in comparison with values reported in younger adults. However, plasma Se and carotenoids as well as erythrocyte vitamin E in elderly people are close to those reported in adult people. If plasma Se showed no difference between men and women, the three other parameters were significantly higher in women than in men. With regard with cardiovascular risk factors, plasma TBARS were highly positively correlated with total and low-density lipoprotein (LDL) cholesterol in men and women. Plasma carotenoids were also positively correlated with plasma total cholesterol and LDL cholesterol in both sexes. Finally, plasma TBARS were highly correlated with smoking and alcohol consumption. In conclusion, this part of the EVA study shows that some cardiovascular risk factors, like smoking and cholesterol level, are associated with high free radical-induced TBARS levels in the preaging population, although plasma Se and carotenoids as well as erythrocyte vitamin E levels in elderly people were close to those reported in adult younger people.

    Full Text Available Este artículo propone la lectura de las dinámicas donde se arraigó la semiosis de producción y reconocimiento del peronismo y de la estelar figura de Eva Duarte. De esa referencialidad histórica, rescato aquello que pueda ser leído en los textos literarios: una ajustada selección de narraciones cuyo eje central se compone por los textos de Tomás Eloy Martínez y, en complementariedad “Esa mujer” (1965 de Rodolfo Walsh. Lo que importa en este estudio es el análisis de la ficción literaria en torno a las operaciones que este movimiento social –el peronismo– estableció entre sujetos y objetos como mitos especulares definidos en la necesidad de consagración. La emergencia de los textos seleccionados es la problemática del cuerpo en cualquiera de sus figuraciones pero reducido finalmente a un mismo deseo y a una misma producción ideológica: la nación. En ese sentido, tal vez, esta lectura proporcione alguna certeza sobre el cuerpo de Eva Perón como metáfora de la historia argentina y de la literatura argentina como fetiche sustituto de la oralidad. Es posible indagar la matriz espectacular en el discurso novelesco en más de un sentido, puesto que comporta la expansión de la problemática de las identificaciones que, simultáneamente, se insertan en la dimensión sagrada preexistente en la construcción mítica.

    Several novel porcine bocaviruses (PBoVs) have been identified in pigs in recent years and association of these viruses with respiratory signs or diarrhea has been suggested. In this study, an EvaGreen(®)-based multiplex real-time PCR (EG-mPCR) with melting curve analysis was developed for simultaneous detection and grouping of novel PBoVs into the same genogroups G1, G2 and G3. Each target produced a specific amplicon with a melting peak of 81.3 ± 0.34 °C for PBoV G1, 78.2 ± 0.37 °C for PBoV G2, and 85.0 ± 0.29 °C for PBoV G3. Non-specific reactions were not observed when other pig viruses were used to assess the EG-mPCR assay. The sensitivity of the EG-mPCR assay using purified plasmid constructs containing the specific viral target fragments was 100 copies for PBoV G1, 50 for PBoV G2 and 100 for PBoV G3. The assay is able to detect and distinguish three PBoV groups with intra-assay and inter-assay variations ranging from 0.13 to 1.59%. The newly established EG-mPCR assay was validated with 227 field samples from pigs. PBoV G1, G2 and G3 was detected in 15.0%, 25.1% and 41.9% of the investigated samples and coinfections of two or three PBoV groups were also detected in 25.1% of the cases, indicating that all PBoV groups are prevalent in Chinese pigs. The agreement of the EG-mPCR assay with an EvaGreen-based singleplex real-time PCR (EG-sPCR) assay was 99.1%. This EG-mPCR will serve as a rapid, sensitive, reliable and cost effective alternative for routine surveillance testing of multiple PBoVs in pigs and will enhance our understanding of the epidemiological features and possible also pathogenetic changes associated with these viruses in pigs.

    Full Text Available A evasão escolar no ensino superior é um fenômeno complexo e, portanto, não pode ser analisado fora de um contexto histórico mais amplo, pois é reflexo da realidade de níveis anteriores de ensino, influenciando de diversas maneiras para o abandono de um curso superior. A avaliação institucional permeia todos esses processos e pode auxiliar na identificação dos sinais da evasão, reduzindo-a ou mesmo evitando-a. Este artigo analisa a produção teórica que aborda a evasão e a sua relação com a avaliação a partir da Biblioteca Digital de Teses e Dissertações (BDTD entre 2008-2009. A metodologia baseia-se na pesquisa bibliográfica, denominada estado da arte ou estado do conhecimento, que contribui para a discussão e o mapeamento da produção acadêmica tanto em termos de análise qualitativa, quanto quantitativa. Vimos que a relação entre evasão e avaliação ainda é pouco estudada, sendo mais restrita ainda que a reflexão sobre a evasão no ensino superior.The dropout rate of undergraduate students is a complex phenomenon that cannot be analyzed without taking into consideration a wider historical context for it is a consequence of previous educational levels, which influence in several different ways higher education dropout rates. School evaluation permeates all these processes and can help to identify dropout signs, reducing or even preventing it. This article analyzes the theoretical production contained in Digital Library of Thesis and Dissertations which analyzes the dropout issue and its relationship with evaluation between 2008-2009. The methodology is based on bibliographical survey denominated state of the art or state of knowledge, which contributes to the discussion and mapping out of the academic production both in terms of qualitative and quantitative analyses. We found that the relationship between dropout rates and evaluation has received little scholarly attention, being even more scarce than the studies

    The fundamental properties of transdermal therapeutic patch as narcotic analgesics agent has been investigated. From the study of drug and ethanol release patterns from the fentanyl base (FB) patches through diffusion cell and hairless mouse skin, it was observed that the FB release patterns were largely affected by the content of vinyl acetate (VA) of ethylene-co-vinyl acetate (EVA) membrane, and volume fraction of ethanolic solution. Additionally, a variety of control membrane as a function of VA content were examined for swelling following equilibration with ethanolic solutions. Generally, ethanol was incorporated into a transdermal therapeutic device to enable the controlled delivery of enhancer and drug to the skin surface. In vitro skin permeation analysis of the control membrane showed that ethanol flux was linearly related to the ethanol volume fraction. This result was shown that drug permeability increased with increasing as the content of VA. But, the FB flux from saturated aqueous ethanol solutions increases until 80% ethanol volume fraction. Over 80% ethanol volume fraction, the FB flux through skin samples is independent of ethanol volume. These results showed that the decrease in skin permeation due to dehydration nis the dominant effect. 26 refs., 8 figs.

  4. Contribution from the ten major emission sectors in Europe and Denmark to the health-cost externalities of air pollution using the EVA model system – an integrated modelling approach

    Directory of Open Access Journals (Sweden)

    J. Brandt

    2013-08-01

    Full Text Available We have developed an integrated model system, EVA (Economic Valuation of Air pollution, based on the impact-pathway chain, to assess the health-related economic externalities of air pollution resulting from specific emission sources or sectors, which can be used to support policy-making with respect to emission control. Central for the system is a newly developed tagging method capable of calculating the contribution from a specific emission source or sector to the overall air pollution levels, taking into account the non-linear atmospheric chemistry. The main objective of this work is to identify the anthropogenic emission sources in Europe and Denmark that contribute the most to human health impacts. In this study, we applied the EVA system to Europe and Denmark, with a detailed analysis of health-related external costs from the ten major emission sectors and their relative contributions. The paper contains a thorough description of the EVA system, the main results from the assessment of the main contributors and a discussion of the most important atmospheric chemical reactions relevant for interpreting the results. The main conclusion from the analysis is that the major contributors to health-related external costs are major power production, agriculture, road traffic, and non-industrial domestic combustion, including wood combustion. We conclude that when regulating the emissions of ammonia from the agricultural sector, both the impacts on nature and on human health should be taken into account. This study confirms that air pollution constitutes a serious problem for human health and that the related external costs are considerable. The results in this work emphasize the importance of defining the right questions in the decision-making process. The results from assessing the impacts from each emission sector depend clearly on the assumption that the other emission sectors are not changed, especially emissions changing concentrations of

    2013-08-01

    Full Text Available Este ensaio tem como objeto de análise as relações de gênero presentes no romance A paixão da Nova Eva (1977, da escritora inglesa Angela Carter, em diálogo com o filme A pele que habito (2011, do cineasta espanhol Pedro Almodóvar. Nas obras em questão, referenciaremos atenção especial às personagens Evelyn, no romance, e Vicente, no filme, que passam por um processo transexualizador que inclui, além da mutilação fisica de seus corpos masculinos, uma posterior tentativa de internalização das suas novas condições de „mulher‟. Nas duas obras, há um processo de aculturação e socialização do que se concebe como constituinte do „ser mulher‟, levando a cabo a icônica frase de Beauvoir: “Não se nasce mulher, torna-se”. Nesse sentido, tanto o texto literário quanto o filme incorporariam a sexualidade como um dispositivo, marcado pelo caráter performativo das identidades de gênero e pelo alcance subversivo das performances e das sexualidades fora das normas de gênero pré-estabelecidas. Além disso, torna-se evidente uma concepção do corpo como núcleo do biopoder, „fabricado‟ por tecnologias precisas. Notamos, nas duas alegorias em análise, uma ilustração das identidades de gênero enquanto constructo social e cultural presentes nas postulações de Foucault (2004, Louro (2005, Butler (2003 e Lauretis (1994.

  6. How to prevent mind-wandering during an EVA ? Presentation of a mind-wandering detection method using ECG technology in a Mars-analog environment

    Gontier, Camille

    2017-11-01

    The purpose of this study is to detect mind-wandering in an Extra-Vehicular Activity (EVA) context during a long supervision task. Detection is realized using an electro-cardiogram and measures of heart rate variability. Experienced by everyone, mind-wandering depicts the state of mind where thoughts are not related to the current action. Its deleterious aspect regarding performance suggests a need to take mind-wandering seriously as an impediment to manned space missions' safety. Previous research confirmed the hypothesis according to which several physiological responses can be used to track down mind-wandering. ECG recordings are both easy to obtain and analyze, statistically related to mind-wandering, and easy to record during extra-vehicular activities. Data analyzed in this paper have been recorded during a Mars-analog mission (MDRS 164), from February 20 to March 6, 2016 at the Mars Desert Research Station (Utah). During various cognitive tasks, the subject had his ECG and awareness levels monitored at the same time to see if a correlation between these two measures can be used in a Mars-mission environment. At different time intervals, the subject was interrupted using the thought probe method to inquire about his thoughts. Heart Rate Variability (HRV, which power in high frequencies is related to the parasympathetic system and is expected to vary with mind-wandering) was then computed from recorded data, and its statistical changes during on-task and off-task thoughts were assessed. Although data revealed no significant differences nor coherent trends in HRV-related metrics between the two conditions, results are paving the way towards a better understanding of ECG-recordings and their use during space-analog missions.

    Hormone replacement therapy (HRT) may reduce atherosclerosis among postmenopausal women, partly by reducing vascular endothelium damage. We have tested this hypothesis by evaluating the association of HRT with firstly, carotid intima media thickness (IMT) and plaques, and secondly, with endothelial cell damage, indicated by soluble thrombomodulin (sTM). Then, we tested the association between the two markers of atherosclerosis and the levels of sTM. Among 747 postmenopausal women included into the EVA study, we compared 154 HRT users (including 80% transdermal treatment) with 593 never users. Carotid IMT and plaques were measured with B-mode ultrasonography and sTM with ELISA. At least one plaque was detected among 13.6% of HRT users and 27.3% of never users. After adjustment for confounding factors, the odds ratio for the presence of plaque was 0.45 (95% confidence interval, 0.25-0.78, P=0.005) in HRT users in comparison with nonusers. HRT users had a slightly lower crude mean IMT than nonusers, but the difference was not significant. sTM was positively associated with mean IMT (P for trend=0.001) but not with plaques. Finally, estrogen users had a lower sTM level than nonusers (difference 0.14 ng/ml, P=0.03). As HRT was associated with sTM and plaques, but not with IMT, while sTM was only associated with IMT, our hypothesis was not confirmed. This suggests that the possible beneficial effects of HRT on atherosclerosis may not go through the endothelial cell damage assessed by plasma thrombomodulin.

    Full Text Available This paper discusses the possibility of further completing the to-date analyses on the content and scope of the painting program in the Mileševa narthex, representing a striking two-band frieze of the images of holy monks. This new examination does not ignore the already recognized distinguishing marks, and pays special attention to investigating possible relationships and links with the solutions in some other monuments of the same era not having been previously researched in detail. The undertaking of the author was in this case determined by an attempt to look into and throw some light onto the hardly discernible, and to date unexplained, original content of a smaller, only fragmentarily saved, and indeed the most challenging segment of that numerous and complex gathering of the images of holy monks. That segment included several extremely damaged and rather faded images of holy monks in the lower zone of the narthex southern wall (the band of standing figures, and the figure in the southern end of the adjoining, west wall, in all probability, belonged to it as well. Furthermore, according to the faded traces of previous iconographic characteristics of these figures, it could be seen that they constituted a compact and specific group with regard to the nearest images or groups of images, related to them by belonging to the same, more general category of the holiness. Bearing in mind the damage to heads and faces, as well as the disappearance of the inscription with the names and texts on the scrolls in their hands, the only way to discovering, or at least to closer determining the identity of the images presented was by means of to date unused circumstantial data, which could be provided by more extensive iconographic materials from the other monuments of the time. This way was, up to a certain extent, already open by previous numerous notes of the researchers on the essential closeness of solutions in Mileševa with those of Studenica and

    This contribution presents the description and interpretation of carbonate microfacies of the San Juan Formation (Ordovician) at the Niquivil section, considering the stratigraphical interval between the Oepikodus evae and Oepikodus intermedius conodont zones. The distribution of the microfacies and the conodonts assemblages allow us to identify different sub-environments within the late Floian carbonate ramp of the Central Precordillera. Five microfacies were recognized from the base to the top: M1 Bioclastic mudstone-wackestone; M2 Bioclastic-peloidal wackestone; M3 Intra-bioclastic wackestone; M4 Intra-bioclastic packstone; M5 Peloidal grainstone. The vertical distribution of these microfacies indicates a shallowing trend of the carbonate ramp in the Niquivil section for this temporal interval, which suggests a middle ramp environment with low energy, without wave action, and that evolved towards the middle-inner ramp environment with more energy by wave action and development of tempestites. [Spanish] En la presente contribución se realiza la descripción e interpretación de las microfacies carbonáticas de la Formación San Juan (Ordovícico) en la sección de Niquivil, considerando el intervalo estratigráfico comprendido entre las zonas de conodontos Oepikodus evae y Oepikodus intermedius. El análisis de las microfacies y los conodontos asociados permiten el reconocimiento de diferentes subambientes carbonáticos dentro de la rampa carbonática desarrollada durante el Floiense tardío de la Precordillera Central. Se reconocieron cinco microfacies que, de base a techo, son: M1 Mudstone-Wackestone bioclástico; M2 Wackestone bioclástico-peloidal; M3 Wackestone intra-bioclástico; M4 Packstone intra-bioclástico; M5 Grainstone peloidal. La interpretación vertical de estas microfacies indica una tendencia hacia la somerización de la rampa carbonática en la sección de Niquivil para el lapso temporal estudiado.

    Full Text Available O presente estudo teve como objetivo investigar os fatores que motivaram a evasão de alunos ingressantes em 2005 no curso de Licenciatura Plena em Educação Física da Universidade Federal do Piauí. Inicialmente, utilizaram-se informações (nome, contato telefônico, período de egressão e endereço fornecidas pela coordenação do curso a cerca dos 66 alunos ingressantes em 2005 via vestibular. Os demais dados, pessoais e acadêmicos, foram coletados mediante a aplicação de questionários junto aos alunos diplomados em tempo ideal e aos alunos declarados evadidos do curso. A amostra foi composta por 10 alunos diplomados e 11 alunos evadidos. A pesquisa empírica foi realizada no período de agosto a novembro de 2010. Os resultados da pesquisa revelaram que os fatores responsáveis pela evasão dos alunos foram: falta de informações sobre o curso, descontentamento com a profissão, imaturidade ao escolher o curso, pouca interação com o curso, e, simultaneidade de dois cursos. Verificou-se três situações distintas que circundam o processo de evasão do aluno. A primeira é caracterizada pelo abandono do curso de Educação Física para concluir um segundo curso já iniciado; a segunda consiste no abandono do curso para iniciar outro; e a terceira situação caracteriza-se pela evasão total do ensino superior. Conclui-se como principal fator responsável pela evasão do grupo de alunos avaliado, a escolha do curso de maneira equivocada e precipitada por parte do aluno.This study aimed to investigate the factors that led to the desertion of new students in 2005 from the undergraduate Physical Education program at the Federal University of Piauí.

    Full Text Available Eva Blome setzt sich in ihrer umfassenden Dissertation erstmalig aus literaturwissenschaftlicher Perspektive mit den interdiskursiven Transformationen des Themas ‚Rassenmischung‘ im deutschen kolonialen Kontext auseinander. Die Autorin nimmt den Einsatz der ‚Rassenmischung‘ als biopolitische und poetologische Argumentationsfigur in den Fokus, indem sie die deutschsprachige Kolonialliteratur um 1900 und die Kunst und Literatur des europäischen Primitivismus behandelt und sich abschließend mit den Kultur- und Rassentheorien der Weimarer Republik beschäftigt. Zentrale Verdienste des Buches liegen darin, dass eine Forschungsnische gefüllt und weiterführende Forschungsfragen zum Thema ‚rassisch‘ transgressiver Sexualität aufgeworfen werden.

    Full Text Available Este ensayo examina dos novelas y una biografía publicadas a mediados de los noventa que construyen imágenes de Eva Perón a partir de textos de la época y de la sucesivas recreaciones que se han hecho desde entonces. Aunque utilizan las mismas fuentes y hasta las mismas anécdotas, estos relatos ofrecen retratos considerablemente diferentes y no sólo por razones ideológicas. En una época como la actual, en la que el cientista social o el novelista tienen conciencia de que no pueden hablar por el otro, y menos en el caso de un personaje histórico sobre el que se ha construido una mitología, la modalidad narrativa adquiere especial importancia. Mientras en un caso se destruye toda pretensión de recuperar la verdad (Santa Evita, los otros dos relatos confían en la posibilidad de proponer nuevas interpretaciones. Estas representaciones evocan también consideraciones de género, es decir, revelan una conciencia de que se representa a una mujer que transgredió los cánones de su época logrando transformarse en líder de un movimiento político. Si bien es cierto que la intimidad de Eva continúa siendo elusiva, los tres relatos nos permiten entender desde nuestro tiempo la vida de una mujer que se definió a sí misma y cuyas decisiones tuvieron consecuencias realesThis essay examines two novels and a biography published in the mid-90s that construct images of Eva Perón originating in texts of her own time and in successive recreations that have been done since then.

In an age such as ours, in which the social scientist and the novelist realize that they cannot speak for the other, and much less in the case of a historical figure who has become a myth, the discursive modality adopted acquires special significance.

The focus is not merely on the unconscious as an object of the sciences, but on the role of the unconscious as a subject of knowledge organization and knowledge production, as “crisis and capital” of the sciences, indeed simultaneously functioning as sand and oil in the transmission of knowledge. In place of a systematic overview, the interdisciplinary volume offers a number of clever, sometimes surprising, and always well-worth reading perspectives on the visual and political unconscious, its history of knowledge, and its place in the order of knowledge.

    Full Text Available A evasão em Instituições de Ensino Superior (IES públicas e privadas está associada com perdas sociais, acadêmicas e econômicas consideráveis. Essas perdas afetam toda a sociedade, já que os cidadãos pagam, direta ou indiretamente, pela sua própria educação e a dos seus familiares. O principal objetivo deste estudo foi analisar o comportamento de evasão dos estudantes matriculados nos cursos de graduação em Administração de Empresas e Ciências Contábeis em IES brasileiras entre 2001 e 2010. As taxas de evasão foram pesquisadas por tipo de IES e correlacionadas com o percentual de estudantes que concluíram os seus cursos dentro do prazo ideal. As hipóteses foram testadas com o teste ANOVA, e as variáveis foram submetidas à análise de correspondência simples e múltipla. As estatísticas descritivas mostraram níveis mais altos de evasão nos cursos de Administração de Empresas do que em Ciências Contábeis, porém em níveis gerais mais baixos quando comparados com a literatura. O índice de prazo ideal de conclusão do curso foi maior para Ciências Contábeis, embora não significativamente. Menos de um quarto dos estudantes concluíram os seus cursos dentro do período esperado de cinco anos. Em geral, as conclusões indicam que os cursos de Ciências Contábeis têm taxas menores de evasão nas universidades e nos centros universitários, enquanto os cursos de Administração de Empresas têm taxas maiores de evasão nas faculdades, escolas, institutos e centros de ensino tecnológico. Os resultados deste estudo não pretendem ser uma generalização, mas representam padrões observados dentro das classificações adotadas no estudo.

Se hace un esbozo del estatus de la figura femenina en el imaginario androcéntrico occidental, desde sus raíces judeocristianas y de pensamiento clásico, hasta el advenimiento de la modernidad. Se reseñan postulados acerca del estatus del cuerpo femenino y la forma en que se construye en las representaciones gráficas; se parte de que la manera en que el cuerpo femenino es representado en la publicidad, enfocada a atraer turistas a la playa, le genera una doble otredad. La primera como mujer, cuyo físico es controlado por un imaginario androcéntrico que lo usa cual Eva-sirena, que tienta y atrae al posible visitante. La segunda como elemento que recrea una fantasía de exploración colonial de una playa prístina y “virginal”, y que la aleja de la modernidad racional cartesiana, en la cual la mente se impone a un cuerpo que debe ser controlado y domesticado por la razón.

    Although the Brazilian gas market has been showing steady growth and positive news regarding new discoveries, it is not immune to be questioned about its capacity of value generation, and, in particular, if the new companies, operating in distribution have generated it. Value creation, and its management, has become one of the main activities of the modern corporation in order to align the management and shareholders interests. Despite its advancements, the Brazilian NG industry can be considered at its early stages when compared to those of other countries whose industry is more traditional and mature. The process of unbundling of the gas industry, as well as of the public utilities, has become one of the icons of the Brazilian government policies since the mid 90's. Taking into account regulatory change which had only allowed in the last couple of decades the participation of private ownership into the domestic gas market, a follow up of these companies' performances is of interest. Following the concept of value generation, the present study examines the Brazilian gas distribution sector. Based on a detailed analysis of the financial statements of some of the main companies in the sector, that together represent around 68% of the total Brazilian market, this paper verifies whether the gas distribution sector have presented a positive or negative EVA{sup R}, in other words, if, during the period from 2002 to 2007, these newly companies in the gas industry have created or destroyed value in Brazil.

    To assess the performance of a simplified MRI protocol consisting of a contrast-enhanced three-dimensional MR angiography (CE-MRA) in association with a post-contrast T1-weighted sequence (T1WIV) for the detection of HNPGLs in SDHx mutation carriers. This retrospective sub-study is based on the multicenter PGL.EVA cohort, which prospectively enrolled SDHx mutation carriers from 2005 to 2009; 157 index cases or relatives were included. CE-MRA and the T1WIV images were read solely with knowledge of the clinical data but blind to the diagnosis. Sensitivity, specificity and likelihood ratios for the simplified MRI protocol were compared to the full MRI protocol reading results and to the gold standard status obtained through the consensus of an expert committee. The sensitivity and specificity of the readings of the simplified MRI protocol were, respectively, 88.7 % (95 % CI = 78.1-95.3) and 93.7 % (95 % CI = 86.8-97.7) versus 80.7 % (95 % CI = 68.6-89.6) and 94.7 % (95 % CI = 88.1-98.3) for the readings of the full MRI protocol. The simplified post-contrast MRI with shorter duration (5 to 10 minutes) showed no performance difference compared to the lengthy standard full MRI and can be proposed for the detection of head and neck paragangliomas (HNPGLs) in SDHx mutation carriers.

Unfortunately, the texts lack a solid theoretical foundation as well as clear definitions of the terminology, which would have been helpful for understanding the category of the ‘spectacle.’ Thus, the volume fails to coherently integrate the individual articles into its overall context.

Ao analisar a carreira dos especialistas em Políticas Públicas e Gestão Governamental (EPPGG, o artigo contribui à literatura sobre motivação no serviço público, que enfatiza a importância dos fatores motivacionais intrínsecos. A análise mostra que: i a evasão relaciona-se a fatores extrínsecos, ligados à remuneração, enquanto ii a satisfação relaciona-se não apenas a fatores extrínsecos, mas principalmente a fatores intrínsecos e simbólicos, ligados à natureza do trabalho. A contribuição à agenda de pesquisas reforça a importância de se considerar lógicas institucionais e aspectos culturais das carreiras públicas em estratégias para investigar as dinâmicas motivacionais que afetam as decisões profissionais dos servidores.

  20. A comparison of observed extreme water levels at the German Bight elaborated through an extreme value analysis (EVA) with extremes derived from a regionally coupled ocean-atmospheric climate model (MPI-OM)

    2017-04-01

    As a consequence of climate change atmospheric and oceanographic extremes and their potential impacts on coastal regions are of growing concern for governmental authorities responsible for the transportation infrastructure. Highest risks for shipping as well as for rail and road traffic originate from combined effects of extremes of storm surges and heavy rainfall which sometimes lead to insufficient dewatering of inland waterways. The German Ministry of Transport and digital Infrastructure therefore has tasked its Network of Experts to investigate the possible evolutions of extreme threats for low lands and especially for Kiel Canal, which is an important shortcut for shipping between the North and Baltic Seas. In this study we present results of a comparison of an Extreme Value Analysis (EVA) carried out on gauge observations and values derived from a coupled Regional Ocean-Atmosphere Climate Model (MPI-OM). High water levels at the coasts of the North and Baltic Seas are one of the most important hazards which increase the risk of flooding of the low-lying land and prevents such areas from an adequate dewatering. In this study changes in the intensity (magnitude of the extremes) and duration of extreme water levels (above a selected threshold) are investigated for several gauge stations with data partly reaching back to 1843. Different methods are used for the extreme value statistics, (1) a stationary general Pareto distribution (GPD) model as well as (2) an instationary statistical model for better reproduction of the impact of climate change. Most gauge stations show an increase of the mean water level of about 1-2 mm/year, with a stronger increase of the highest water levels and a decrease (or lower increase) of the lowest water levels. Also, the duration of possible dewatering time intervals for the Kiel-Canal was analysed. The results for the historical gauge station observations are compared to the statistics of modelled water levels from the coupled

    Full Text Available Purpose of the article: In the Czech Republic, the concept of value-based managenet with the indicator of Economic Value Added (EVA has come into the foreground in recent years. Currently, a range of important authors (e.g. Kislingerová, Mařík, and Neumaierová is focused on this problem but no one of them describes effects of accounting data transformation on the items of financial statements while these data are intented to be taken from the managerial point of view. The managerial view on accounting data is necessary at calculation of EVA indicator. Then, this article is focused on the adjustments of financial statements prepared under the Czech accounting law in order to transform them into managerial data in accordance with the substance of value-based management. Methodology/methods: In the submitted paper, the logic-based methods are applied. Here, there are especially pair methods of analysis and synthesis. Chosen items of financial statements prepared under the Czech accounting law are analysed while synthesis forms a headstone of preparation of the financial statements for the value-based management based on economic value added. Scientific aim: The aim of the submitted paper is the methodological description of the effect of chosen accounting items transformation into managerial data. Especially the items of balance sheet and profit and loss statement are discussed in order to determinate disproportions between accounting and managerial point of view at EVA calculation. Findings: This article provides specific information about the methodology of accounting data transformation from the managerial point of view in order to calculate properly the indicator of NOPAT. The methodology is elaborated also in table illustration which includes the relations among accounting entries on the accounts, and the items of the balance sheet and profit and loss statement.

    Background: NASA Strategic Knowledge Gap B5: Forward Contamination for Mars. Issue: we have knowledge gaps!: Whether / how microbes are released from crewed pressure systems. Why do we care?: Informs Mars operational concepts - How to protect the science; Informs architecture decisions - How “open” Environmental Control and Life Support (ECLS) systems are; Informs landing site selection decisions - How close we can land / operate to where life may be present. Project goal: get some data to fill in these gaps: Data will help determine whether we’re ready to go to Mars, or if we need to change our systems or operational designs.

  15. A "lei da vida": confirmação, evasão escolar e reinvenção da identidade entre os pomeranos The "law of life": confirmation, school drop out and reinvention of identity among Pomeranians

    Full Text Available O artigo analisa o significado do índice de evasão escolar na vida de uma comunidade de pequenos produtores rurais, imigrantes vindos da região da Pomerânia, norte da Alemanha. A população do município escolhido é composta por 90% de descendentes de pomeranos, que lá chegaram no ano de 1847. Embora o Espírito Santo não receba mais alemães desde a década de 1870, essas comunidades mantiveram o uso de seu dialeto, suas festas, seus costumes culturais e maritais, a continuidade da narrativa da tradição oral camponesa, enfim, o modo de vida camponês. No contexto da imigração brasileira, nenhuma outra etnia se concentrou tanto em áreas homogêneas e compactas como esta, concorrendo para modificar a estrutura fundiária e a vida rural dos estados onde se estabeleceu. Este trabalho aborda a relação entre o uso de várias línguas (portuguesa, alemã e pomerana e a religiosidade luterana no cotidiano do grupo, os padrões de transmissão da herança da terra e a consequente valorização destes elementos no ensino confirmatório empreendido pela igrejas Luterana e Missouri, como pontos que permitem compreender os valores sociais e educacionais mais importantes para o grupo na reprodução da sua condição campesina. São examinadas as representações do grupo acerca do papel social desempenhado pela escola, pelo professor e pelo pastor, e sua relação com os elementos mantenedores de seu ethos camponês: a obediência às regras de reciprocidade, a conformidade com os princípios de hierarquia (autoridade paterna e pastoral e a solidariedade com parentes e vizinhos.The article deals with the meaning of school drop out in the life of a small comunity of rural workers descendants of Pomeranians - immigrants originally from the northern German.

    Full Text Available This paper presents the results obtained from the archaeological intervention carried out in the ancient mine of Doña Eva/José Martín Palacios (Baños de la Encina, Jaén. This excavation has allowed us to confirm the hypothesis formulated after the initial campaign, that the mine was exploited in two different phases, the first one during the Bronze Age and the second one in Roman times. This is the first mine in the Southeast of the Iberian Peninsula that has been convincingly assigned to the Bronze Age based both on the recovered ceramic material as well as Carbon 14 results. In addition, we have also found traces of the reduction process (slag, smelting crucibles. These have only been documented at three mines in the Iberian Peninsula.Se presentan los resultados de la excavación arqueológica en la mina antigua de José Martín Palacios/Doña Eva (Baños de la Encina. Los resultados confirman y corroboran las hipótesis, planteadas tras los trabajos de campo de 2003 en la cuenca del Rumblar (Jaén, de que la mina tuvo, al menos, dos periodos de explotación: uno en la Prehistoria Reciente (Edad del Bronce y otro en época romana. Hasta el momento, la mina es la primera del sureste de la Península Ibérica excavada y datada en la Edad del Bronce por carbono 14 y por el material cerámico recuperado. Además se han hallado restos del proceso de reducción metalúrgica (escoria y un fragmento de vasija horno, constatado sólo en tres minas peninsulares más.

    Nonsteroidal anti-inflammatory drugs (NSAIDs) are responsible for 21-25% of reported adverse drug events which include immunological and nonimmunological hypersensitivity reactions. This study presents up-to-date information on pathomechanisms, clinical spectrum, diagnostic tools and management of hypersensitivity reactions to NSAIDs. Clinically, NSAID hypersensitivity is particularly manifested by bronchial asthma, rhinosinusitis, anaphylaxis or urticaria and variety of late cutaneous and organ-specific reactions. Diagnosis of hypersensitivity to a NSAID includes understanding of the underlying mechanism and is necessary for prevention and management. A stepwise approach to the diagnosis of hypersensitivity to NSAIDs is proposed, including clinical history, in vitro testing and/or provocation test with a culprit or alternative drug depending on the type of the reaction. The diagnostic process should result in providing the patient with written information both on forbidden and on alternative drugs. © 2011 John Wiley & Sons A/S.
