Full Text Available The Hlučín Region is a small border area in the Moravia-Silesia Region. Its history is specific. Over 25 years in the 20th century, its border shifted three times and its inhabitants’ nationality also changed three times. The region was annexed by the German Reich in 1938 and its inhabitants gained the rights of citizens of the Reich, with the obligation to enlist in the Wehrmacht, the armed forces of Germany. These historical turning points and their consequences after the Second World War are part of the cultural and communicative memory of most of the local people. The purpose of the article is to show the communicative memory of Hlučín Region inhabitants and the common knowledge of 20th century historical events to be one of the important integral parts of regional identity, which is a source of regional consciousness. Hlučín Region inhabitants identify themselves strongly with their region and society. This identification results from specific culture finding its expression in shared values, faith and traditions, and from the awareness of their own specificity. As a consequence of the predominant regional endogamy, this culture is handed down from one generation to another. Strong regional consciousness based on this identification, has a positive influence on the rich communal life and possibilities of stabilization and further development of the region.

Smell, Space and Othering

Full Text Available Currently experiencing social shift from the rural/coastal to the urban, Matnog, Sorsogon, in the Philippines is left with markings of people who live by the coast, who are confronted by poverty, a poverty which can easily be seen in the space they occupy. The present article concerns itself less with seeing, but rather forms a spin-off from the spatial discourse to that of the smell/scent of a woman enmeshed with the space she inhabits and enabling the unfolding of the reproduction of social differences. As a way of knowing, a methodology, in this embodied qualitative research, the scent/smell becomes the agent and the space as the agency of power are both explored as a purview in cultural studies. The sense of smell as a sociocultural construction that establishes social identity and reifies and reproduces social differences is highlighted and positioned. Extrapolating from field work conducted in Matnog demonstrates that the smell of this rural space is rapidly transitioning to that of the urbane and the smell of women who inhabits that space. Through narrative poetry and the presentation of photographs and verbal analyses, olfactory identities and imprints, social differences, identity and spaces are explored, culminating in the transitional reconfiguration of poverty constructs.

The island of Vis belongs to middle Dalmatian group of islands with caracteristics Mediterranean climate. The assumption was that the dominant diet of the inhabitants is also Mediterranean. Such diet is considered to be one of the best for the prevention of many complex and chronic diseases, as confirmed by numerous studies in different parts of the World. This study showed a shift in dietary habits in the direction of a more globalized diet. Such sudden shift may prove to be an important trigger for the development of complex diseases such as diabetes melitus type 2, cardiovascular diseases, gout, as well as certain types of cancer.

1972-11-01

To grasp the effects of air pollution on the human body in smaller cities, lead content and CO--Hb (carboxyhemoglobin) in blood were examined in inhabitants of Soka City, Saitama Prefecture, as well as the factors of living. The inhabitants are nonuniform as an occupational population, however, from the point of view that the work places are located in the same city they are considered to be uniform as an occupational population. In the city, the Pb content of air was 6, 2 to 5 and 1 microgram/cu m, respectively, in highly, moderately, and slightly polluted areas. The Pb content of blood of inhabitants in highly polluted areas in the city was on the arithmetical average - 15 micrograms/dl, and CO--Hb in the same individuals was 1.8% (2.6% in smokers and 1.2% in nonsmokers). These figures mean that the effect of air pollution was very slight in the inhabitants in this city.

There is a general concern on the possible hazardous health effects of exposure to radiofrequency electromagnetic radiations (RFR) emitted from mobile phone base station antennas on the human nervous system. To identify the possible neurobehavioral deficits among inhabitants living nearby mobile phone base stations. A cross-sectional study was conducted on (85) inhabitants living nearby the first mobile phone station antenna in Menoufiya governorate, Egypt, 37 are living in a building under the station antenna while 48 opposite the station. A control group (80) participants were matched with the exposed for age, sex, occupation and educational level. All participants completed a structured questionnaire containing: personal, educational and medical histories; general and neurological examinations; neurobehavioral test battery (NBTB) [involving tests for visuomotor speed, problem solving, attention and memory]; in addition to Eysenck personality questionnaire (EPQ). The prevalence of neuropsychiatric complaints as headache (23.5%), memory changes (28.2%), dizziness (18.8%), tremors (9.4%), depressive symptoms (21.7%), and sleep disturbance (23.5%) were significantly higher among exposed inhabitants than controls: (10%), (5%), (5%), (0%), (8.8%) and (10%), respectively (Pstation exhibited a lower performance in the problem solving test (block design) than those under the station. All inhabitants exhibited a better performance in the two tests of visuomotor speed (Digit symbol and Trailmaking B) and one test of attention (Trailmaking A) than controls. The last available measures of RFR emitted from the first mobile phone base station antennas in Menoufiya governorate were less than the allowable standard level. Inhabitants living nearby mobile phone base stations are at risk for developing neuropsychiatric problems and some changes in the performance of neurobehavioral functions either by facilitation or inhibition. So, revision of standard guidelines for public

Inhabiting compassion: A pastoral theological paradigm

Directory of Open Access Journals (Sweden)

Phil C. Zylla

2017-08-01

Full Text Available Inspired by the vision of care in Vincent van Gogh’s depiction of the parable of the Good Samaritan, this article offers a paradigm for inhabiting compassion. Compassion is understood in this article as a moral emotion that is also a pathocentric virtue. This definition creates a dynamic view of compassion as a desire to alleviate the suffering of others, the capacity to act on behalf of others and a commitment to sustain engagement with the suffering other. To weave this vision of compassion as a habitus rather than a theoretical construct, the article develops three phases of compassion: seeing, companioning and sighing. This framework deepens and augments a pastoral theological paradigm of compassion with the aim of inculcating an inhabited compassion in caregivers and the communities in which they participate.

1975-04-01

The reaction of inhabitants to auto exhaust, noise, and vibration was surveyed in commercial and residential quarters by inquiries and measurement of the carbon monoxide in expired air of the inhabitants. About 65 percent of the inhabitants of busy quarters complained of severe reactions to auto exhaust, noise, and vibration; physical effects included headache, absentmindedness, loss of appetite, prickling of eyes, pain in the throat, and frequent colds. The concentration of carbon monoxide in the expired air of inhabitants of residential quarters was about 5 ppM, and in the busy quarter with much motor traffic the concentration was about 10 ppM. The concentration of carboxyhemoglobin in blood of the latter averaged 2.5 to 2.6 percent, and the former was 1.5 percent. The data were taken among non-smokers, and there were socio-economic differences among inhabitants of both quarters.

Encountering local inhabitants' perspectives in terms of authenticity: The example of rural tourism in southern Germany

Directory of Open Access Journals (Sweden)

T. Weidinger

2015-05-01

Full Text Available Effects of globalisation and various standardisation processes in everyday life are currently reflected through individuals’ quests for encountering authenticity. The paper interrogates in which particular ways local inhabitants evaluate rural localities with regard to authenticity by means of local architectural styles and filmic representations. Empirical findings from two qualitative studies carried out in rural Southern Germany are presented. The studies were comprised of qualitative interviews with local inhabitants and representatives in tourism, politics and heritage conservation together with a film analysis of a popular Heimat film shot in the Bavarian forest. Results reveal locals’ critique of modern architectural styles such as “Tuscan houses” as inauthentic, whereby a link between architecture and regional identity (“archidentity” cannot be established. However, the film analysis brings forth locals’ congruities between filmic representations and their lived spaces. In sum, locals’ perspectives on authentication processes can contribute to re-evaluate localities that are mainly shaped by idealised images for tourism purposes.

Reproduction in the space environment: Part I. Animal reproductive studies

Santy, P. A.; Jennings, R. T.; Craigie, D.

1990-01-01

Mankind's exploration and colonization of the frontier of space will ultimately depend on men's and women's ability to live, work, and reproduce in the space environment. This paper reviews animal studies, from microorganisms to mammals, done in space or under space-simulated conditions, which identify some of the key areas which might interfere with human reproductive physiology and/or embryonic development. Those space environmental factors which impacted almost all species included: microgravity, artificial gravity, radiation, and closed life support systems. These factors may act independently and in combination to produce their effects. To date, there have been no studies which have looked at the entire process of reproduction in any animal species. This type of investigation will be critical in understanding and preventing the problems which will affect human reproduction. Part II will discuss these problems directly as they relate to human physiology.

Application of artificial intelligence (AI) concepts to the development of space flight parts approval model

Krishnan, Govindarajapuram Subramaniam

1997-12-01

The National Aeronautics & Space Administration (NASA), the European Space Agency (ESA), and the Canadian Space Agency (CSA) missions involve the performance of scientific experiments in Space. Instruments used in such experiments are fabricated using electronic parts such as microcircuits, inductors, capacitors, diodes, transistors, etc. For instruments to perform reliably the selection of commercial parts must be monitored and strictly controlled. The process used to achieve this goal is by a manual review and approval of every part used to build the instrument. The present system to select and approve parts for space applications is manual, inefficient, inconsistent, slow and tedious, and very costly. In this dissertation a computer based decision support model is developed for implementing this process using artificial intelligence concepts based on the current information (expert sources). Such a model would result in a greater consistency, accuracy, and timeliness of evaluation. This study presents the methodology of development and features of the model, and the analysis of the data pertaining to the performance of the model in the field. The model was evaluated for three different part types by experts from three different space agencies. The results show that the model was more consistent than the manual evaluation for all part types considered. The study concludes with the cost and benefits analysis of implementing the models and shows that implementation of the model will result in significant cost savings. Other implementation details are highlighted.

A mission to Mars of several years duration requires more demanding standards for all onboard instruments than a 6-month mission to the Moon or the International Space Station. In Part 1, we evaluated generic technologies and suitability to NASA needs. This prior work considered crew safety, device maturity and flightworthiness, resource consumption, and medical value. In Part 2, we continue the study by assessing the current marketplace for reliable Point-of-Care diagnostics. The ultimate goal of this project is to provide a set of objective analytical tools to suggest efficient strategies for reaching specific medical targets for any given space mission as program needs, technological development, and scientific understanding evolve.

Reproduction in the space environment: Part II. Concerns for human reproduction

Jennings, R. T.; Santy, P. A.

1990-01-01

Long-duration space flight and eventual colonization of our solar system will require successful control of reproductive function and a thorough understanding of factors unique to space flight and their impact on gynecologic and obstetric parameters. Part II of this paper examines the specific environmental factors associated with space flight and the implications for human reproduction. Space environmental hazards discussed include radiation, alteration in atmospheric pressure and breathing gas partial pressures, prolonged toxicological exposure, and microgravity. The effects of countermeasures necessary to reduce cardiovascular deconditioning, calcium loss, muscle wasting, and neurovestibular problems are also considered. In addition, the impact of microgravity on male fertility and gamete quality is explored. Due to current constraints, human pregnancy is now contraindicated for space flight. However, a program to explore effective countermeasures to current constraints and develop the required health care delivery capability for extended-duration space flight is suggested. A program of Earth- and space-based research to provide further answers to reproductive questions is suggested.

An extensive phase space for the potential martian biosphere.

Jones, Eriita G; Lineweaver, Charles H; Clarke, Jonathan D

2011-12-01

We present a comprehensive model of martian pressure-temperature (P-T) phase space and compare it with that of Earth. Martian P-T conditions compatible with liquid water extend to a depth of ∼310 km. We use our phase space model of Mars and of terrestrial life to estimate the depths and extent of the water on Mars that is habitable for terrestrial life. We find an extensive overlap between inhabited terrestrial phase space and martian phase space. The lower martian surface temperatures and shallower martian geotherm suggest that, if there is a hot deep biosphere on Mars, it could extend 7 times deeper than the ∼5 km depth of the hot deep terrestrial biosphere in the crust inhabited by hyperthermophilic chemolithotrophs. This corresponds to ∼3.2% of the volume of present-day Mars being potentially habitable for terrestrial-like life.

Multifunctional spaces in slum settlements and their relation to activity pattern case study of Kampung Sangkrah, Surakarta

Science.gov (United States)

Shobirin, Abyzhar; Ramadhanty, Almira Husna; Hardiana, Ana

2018-02-01

Surakarta is a rapidly urbanized city and it causes the limitation of the availability of land within its urban area. This entangled problem is resulting in the development of slum settlements that spread across the city. One of the slum concentration areas is located on Pepe riverbanks downstream area that belongs to Kampung Sangkrah administrative boundaries. Slum settlements are characterized as a densely-populated area lacking of, or absence of, open space. This condition forces slum inhabitants to effectively use their available spaces, even multi-functionally. This research aims to observe how slum inhabitants multi-functionally use the spaces around their houses and determine the typology of multifunctional space and also the factors that influence it. To understand this phenomenon, this research used activity pattern perspectives. The scope of observation covers in-house (internal) space utilizations and neighborhood-level (external) space utilization. The data used for this research were collected primarily through site observations and interviews, using sampling to conduct data collection for in-house activities and space utilization. The analysis was conducted using descriptive method qualitatively. The research concluded that there are three types of multifunctional space utilization within slum settlements, and the utilization of spaces, whether internal or external utilization also varies depending on the inhabitants' economic-related activities.

Architecture and life support systems for a rotating space habitat

Science.gov (United States)

Misra, Gaurav

Life Support Systems are critical to sustain human habitation of space over long time periods. As orbiting space habitats become operational in the future, support systems such as atmo-sphere, food, water etc. will play a very pivotal role in sustaining life. To design a long-duration space habitat, it's important to consider the full gamut of human experience of the environment. Long-term viability depends on much more than just the structural or life support efficiency. A space habitat isn't just a machine; it's a life experience. To be viable, it needs to keep the inhabitants satisfied with their condition. This paper provides conceptual research on several key factors that influence the growth and sustainability of humans in a space habitat. Apart from the main life support system parameters, the architecture (both interior and exterior) of the habitat will play a crucial role in influencing the liveability in the space habitat. In order to ensure the best possible liveability for the inhabitants, a truncated (half cut) torus is proposed as the shape of the habitat. This structure rotating at an optimum rpm will en-sure 1g pseudo gravity to the inhabitants. The truncated torus design has several advantages over other proposed shapes such as a cylinder or a sphere. The design provides minimal grav-ity variation (delta g) in the living area, since its flat outer pole ensures a constant gravity. The design is superior in economy of structural and atmospheric mass. Interior architecture of the habitat addresses the total built environment, drawing from diverse disciplines includ-ing physiology, psychology, and sociology. Furthermore, factors such as line of sight, natural sunlight and overhead clearance have been discussed in the interior architecture. Substantial radiation shielding is also required in order to prevent harmful cosmic radiations and solar flares from causing damage to inhabitants. Regolith shielding of 10 tons per meter square is proposed for the

The human Se status of 8 areas of Kaluga region was studied. The mean serum Se levels 94 mg/l was significantly lower in the south compared to the northern area 126 mg/l. Areas with radioactive pollution possessed higher percentage of persons with low serum Se concentration than in regions without the pollution. Negative influence of radiation on serum Se level was confirmed also by epidemiological data for workers of Chernobil NNP (65 mg/l-workers attending to the reactor and 69 mg/l-for other employees). The same phenomenon was observed for males of Tula region who had taken part in the liquidation of an accident on the Chernobil NNP compared to other inhabitants of Tula region (78 mg/l and 89 mg/l correspondingly). The lowest antioxidant status (serum vitamin E, C and Se concentrations) in towns of Kaluga region with radioactive pollution possessed males of less than 60 years old.

Full Text Available To recognize a city is part of a city branding effort. By recognizing the dwelling, the city's inhabitants are able to create a spatial space in accordance with their easily recognizable cultural identity. In city branding, the memory of a city space is often the main ingredient in strengthening the identity. The efforts to use place making forces at this time are often used to solve the failures in multi-cultural spaces. Evolution in history is part of dynamic space planning as part of the identity of a city.The purpose of this research is to reveal the relationship between the formation of tradition spaces that are able to function in a modern way. The pattern of this relationship will produce spatial planning patterns with special characters as well. Humans as space users play a very big role as a space builder, where the decisions they make are often based on the tradition they have used for generations.The methods used in this study are qualitative, deductive using the theories that have been there before. Field research is used as empirical data in the form of interviews, photographs and field observations was conducted in various existing city spaces in Solo with the purpose to discover the existence of distinctive spatial patterns based on the typical behavior that has been passed down continuously as a result of the cultural process. The resulting discovery is a significant pattern of relationships between humans and their decision-making abilities in city space. This decision is based on self-awareness as part of the space they occupy. In a group, this awareness is part of the tradition's heritage that continues to develop in accordance with the human intellectual development.

Immersive Environments: Using Flow and Sound to Blur Inhabitant and Surroundings

Science.gov (United States)

Laverty, Luke

Following in the footsteps of motif-reviving, aesthetically-focused Postmodern and deconstructivist architecture, purely computer-generated formalist contemporary architecture (i.e. blobitecture) has been reduced to vast, empty sculptural, and therefore, purely ocularcentric gestures for their own sake. Taking precedent over the deliberate relation to the people inhabiting them beyond scaleless visual stimulation, the forms become separated from and hostile toward their inhabitants; a boundary appears. This thesis calls for a reintroduction of human-centered design beyond Modern functionalism and ergonomics and Postmodern form and metaphor into architecture by exploring ecological psychology (specifically how one becomes attached to objects) and phenomenology (specifically sound) in an attempt to reach a contemporary human scale using the technology of today: the physiological mind. Psychologist Dr. Mihaly Csikszentmihalyi's concept of flow---when one becomes so mentally immersed within the current activity and immediate surroundings that the boundary between inhabitant and environment becomes transparent through a form of trance---is the embodiment of this thesis' goal, but it is limited to only specific moments throughout the day and typically studied without regard to the environment. Physiologically, the area within the brain---the medial prefrontal cortex---stimulated during flow experiences is also stimulated by the synthesis of sound, memory, and emotion. By exploiting sound (a sense not typically focused on within phenomenology) as a form of constant nuance within the everyday productive dissonance, the engagement and complete concentration on one's own interpretation of this sensory input affords flow experiences and, therefore, a blurred boundary with one's environment. This thesis aims to answer the question: How does the built environment embody flow? The above concept will be illustrated within a ubiquitous building type---the everyday housing tower

Learning to Inhabit the Forest: Autonomy and Interdependence of Lives from a Mbya-Guarani Perspective.

Science.gov (United States)

Remorini, Carolina

2015-01-01

This chapter examines the ideas of reciprocity, respect, autonomy, and interdependence of lives and the impact of these on children's learning. Using an ecological perspective that recognizes humans' relationship with other living beings that inhabit the forest, this chapter is based on ethnographic research conducted in two Mbya-Guarani communities (Argentina). Respect and reciprocity are key for children to develop as part of the community and the forest and they are related to children's well-being and health. I describe Mbya perspectives on children's growth and development, emphasizing the balance between interdependence and autonomy as complementary goals and values, providing examples of environmentally relevant skills to grow up in the forest. These skills are associated with particular ways of inhabiting the forest, including learning how to walk in it and developing entendimiento (understanding). These make possible children's integration in community life through their participation and collaboration in daily activities. I attempt to articulate these ideas with the theoretical framework of Learning by Observing and Pitching In, especially concerning ways of organizing and supporting children's learning processes in the context of their engagement with multiaged and more experienced group of people. © 2015 Elsevier Inc.

Influence of urban waterfront appearance on public space functions

Directory of Open Access Journals (Sweden)

Iva Hradilová

2012-01-01

Full Text Available Although the issue of urban waterfront is not entirely new, it still represents a very vivid topic. Urban waterfronts have for long been standing in the forefront of many architects and organizations, who are aware of their value and the potential a watercourse carries within the urban interior. A watercourse is an interconnecting element between the urban development and the surrounding countryside and urban waterfronts are the intermediaries of communication. It is exactly in their area where the city - a purely human product with an inner structure and order defined by humans - meets the element of water, which is a purely natural component.What influences the urban structure most is, however, the presence of water in its very basic form i.e. in the form of a river. Its significance and effect on the public space and the inner relations within the body of the settlement vary with the size and the width of the flow, character of the waterfront, architectural layout of the riverbanks and its current utilization. Urban river works as a communication element which meets with the natural features. It seems to be unnatural to define a waterfront space like mono-functional site. This space denies the very essence of the waterfront and the city’s inhabitants appear as unattractive. In this case the very attractive element of water is unable to urban residents to attract together. In general, the quality of the public space is determined by the degree of its utilization by a wider group of inhabitants. It is the inhabitants themselves who imprints the concept of a public space to empty urban spaces.The present form of urban waterfronts is a result of the historical development, attitude and mental state of the society. The architectural appearance of not only the waterfront but also all public spaces is a reflection of the current social values. It gives evidence about the character of the society, the present economic system, the state and thinking

Novel Amalgams for In-Space Fabrication of Replacement Parts

Science.gov (United States)

Cochran, Calvin T.; Van Hoose, James R.; Grugel, R. N.

2012-01-01

Being able to fabricate replacement parts during extended space flight missions precludes the weight, storage volume, and speculation necessary to accommodate spares. Amalgams, widely used in dentistry, are potential candidates for fabricating parts in microgravity environments as they are moldable, do not require energy for melting, and do not pose fluid handling problems. Unfortunately, amalgams have poor tensile strength and the room temperature liquid component is mercury. To possibly resolve these issues a gallium-indium alloy was substituted for mercury and small steel fibers were mixed in with the commercial alloy powder. Subsequent microscopic examination of the novel amalgam revealed complete bonding of the components, and mechanical testing of comparable samples showed those containing steel fibers to have a significant improvement in strength. Experimental procedures, microstructures, and test results are presented and discussed in view of further improving properties.

Active commuting can be influenced by the environment, and examples from abroad show that current environmental changes tend mostly to promote passive forms of commuting. A similar situation of decreasing active commuting might be expected in the Czech Republic. However, little information has been published to date about the issue of active commuting among the inhabitants of our country. Objective: The main objective of the present study is to describe the active commuting patterns of the inhabitants of Liberec city in low and high walkability areas. Methods: A total of 23,621 economically active inhabitants or students of Liberec city aged 6-87 years (34.77 ± 14.39 participated in the study. The data about commuting were retrieved from the national Population and Housing Census of 2011. Geographic information systems were used to objectively analyze the built environment and to calculate the walkability index. Results: Active commuting to/from school or work is used by 17.41% of inhabitants. Active commuting is dominated by walking (16.60% as opposed to cycling (0.81%. Inhabitants who lived in high walkability areas were more likely to actively commute than those living in low walkability areas (OR = 1.54; 95% CI [1.41, 1.68]. Conclusions: This study confirmed the findings of international studies about the effect of the built environment on active commuting among Liberec inhabitants. Active commuters are often those living near or in the city center, which is characterized by high walkability. In Liberec city, walking as a means of active commuting significantly prevails over cycling. One of the reasons might be the diverse topography of the city and the insufficiently developed cycling network.

and creativity. But the relational dependence between the physical space, pedagogics and organisation is widely overlooked when designing these new learning environments as a new spatial design in itself is expected to change the way we teach and learn. Simply changing the space is not enough (Imms & Byers, 2017......) and the intentions of the space can only be fully realised if the inhabitants of the schools completely understand and support the pedagogical principles informing the provision of these spaces (Burke, 2016). This is why three things should be aligned in order for an ILE to work intendedly: creative teaching (the...... teacher), space (the designer) and organisation (management). With my research, I would like to contribute to the understanding of the relationship between the physical learning environment and creative learning processes and the potential of the space as a tool to stimulate creativity.

Visuality, mobility and the cosmopolitan: inhabiting the world from afar.

Science.gov (United States)

Szerszynski, Bronislaw; Urry, John

2006-03-01

In earlier publications based on the research discussed in this article (e.g. Szerszynski and Urry 2002), we argued that an emergent culture of cosmopolitanism, refracted into different forms amongst different social groups, was being nurtured by a widespread 'banal globalism'--a proliferation of global symbols and narratives made available through the media and popular culture. In the current article we draw on this and other empirical research to explore the relationship between visuality, mobility and cosmopolitanism. First we describe the multiple forms of mobility that expand people's awareness of the wider world and their capacity to compare different places. We then chart the changing role that visuality has played in citizenship throughout history, noting that citizenship also involves a transformation of vision, an absenting from particular contexts and interests. We explore one particular version of that transformation--seeing the world from afar, especially in the form of images of the earth seen from space--noting how such images conventionally connote both power and alienation. We then draw on another research project, on place and vision, to argue that the shift to a cosmopolitan relationship with place means that humans increasingly inhabit their world only at a distance.

Designing carbon markets, Part II: Carbon markets in space

International Nuclear Information System (INIS)

Fankhauser, Samuel; Hepburn, Cameron

2010-01-01

This paper analyses the design of carbon markets in space (i.e., geographically). It is part of a twin set of papers that, starting from first principles, ask what an optimal global carbon market would look like by around 2030. Our focus is on firm-level cap-and-trade systems, although much of what we say would also apply to government-level trading and carbon offset schemes. We examine the 'first principles' of spatial design to maximise flexibility and to minimise costs, including key design issues in linking national and regional carbon markets together to create a global carbon market.

Emotional Geographies of the Uncanny: Reinterpreting Italian Transnational Spaces

Directory of Open Access Journals (Sweden)

Maurizio Marinelli

2013-08-01

Full Text Available The 'Emotional Geographies of the Uncanny' section of Cultural Studies Review aims to read transnational spaces constructed and inhabited by Italian migrants and settlers to Australasia as emotional spaces of uncanny perceptions, memories, narratives and identities. Drawing inspiration from the Freudian suggestions about the uncanny (das unheimliche, and later interpretations by Heiddeger, Derrida, Kristeva, Bhabha, Žižek, and Ahmed, we refer to the uncanny as the emotional reaction to something that is, at the same time, familiar and unfamiliar, homely and unhomely. The uncanny then becomes an aesthetic frame through which experiences of migration and colonialism can be read and interpreted. How have Italians experienced the strange un/familiarity of the places to which they have migrated or that they have colonised in Australasia? And, in the process of familiarising the unfamiliar, how have they perceived the strange familiarity of the newly emerged 'Italian' spaces that they have first constructed and then inhabited, outside the boundaries of the Italian Nation, and often within the space of other essentialist Nations? Furthermore, how have they related to the places they have left in Italy: the places to which they have progressively become strangers yet have continued to constitute a central element of their subjectivity?

Nutrient intake and balancing among female Colobus angolensis palliatus inhabiting structurally distinct forest areas: Effects of group, season, and reproductive state.

Understanding intraspecific behavioral and dietary variation is critical for assessing primate populations' abilities to persist in habitats characterized by increasing anthropogenic disturbances. While it is evident that some species exhibit considerable dietary flexibility (in terms of species-specific plant parts) in relation to habitat disturbance, it is unclear if primates are characterized by similar variation and flexibility regarding nutrient intake. This study examined the effects of group, season, and reproductive state on nutrient intake and balancing in adult female Colobus angolensis palliatus in the Diani Forest, Kenya. During July 2014 to December 2015, estimates of nutrient intake were recorded for eight females from three groups inhabiting structurally and ecologically distinct forest areas differing in tree species composition and density. There were differences in metabolizable energy (ME) and macronutrient intakes among groups, seasons, and reproductive states. Most notably, females inhabiting one of the more disturbed forest areas consumed less ME and macronutrients compared to females in the more intact forest area. Contrary to prediction, females in early lactation consumed significantly less ME and macronutrients compared to non-lactating and late lactation females. Despite differences in macronutrient intake, the relative contribution of macronutrients to ME were generally more conservative among groups, seasons, and reproductive states. Average daily intake ratios of non-protein energy to available protein ranged from approximately 3.5:1-4.3:1 among groups. These results indicate that female C. a. palliatus demonstrate a consistent nutrient balancing strategy despite significant intergroup differences in consumption of species-specific plant parts. Data from additional colobine species inhabiting different forest types are required to assess the extent to which nutrient balancing is constrained by phylogeny or is more flexible to local

Erasing Space from Places Brandscapes, Art and the (devalorisation of the Olympic Space

Full Text Available Beyond use, exchange and sign value, current marketing practices have consistently turned on notions of contextual fruition, experience, performativity, affective spaces, atmospheres. The logic of the experience economy has quickly spilled over other realms: architecture and design, security and control, urban planning and law. As the language of brand overflows the marketing jargon to apply to urban events1 and renewal projects, the notion of brandscape becomes increasingly relevant to indicate the institutional engineering of material and immaterial, visible and invisible spaces. Brandscaping is a “more or less successful institutional attempt to inscribe spaces and their inhabitants in their own terms” (Ball and Wood, 2008, in other words, to freeze space, to capture and tame its multiplicity, to make it static, organised, predictable, not in the cumbersome, panoptical way, but rather through affective strategies, by producing, managing and securing “atmospherically enriched experiences” (Klingmann, 2007: 6.

Full text: The highest average radon concentrations in water are found in the Sudety mountains area, located in the south-western part of Poland. This region is known for its beautiful hiking routes, clean environment and also a large number of natural water springs. Some of underground waters with mineralization of more than 1 g/l are mineral waters. Others contain elements with specific medicinal properties and they are called medicinal waters. Among them are radon enriched waters with radon activity equal to at least 74 Bq/l. Waters chosen for investigations were collected in 24 health resorts and towns of the Sudety mountains. Water samples were periodically collected from 118 springs over a period of 10 years. Most of these waters are mineral medicinal waters and are used for treatment for patients and tourists. 16 intakes are treated by inhabitants as drinking water for everyday use. Among them, 6 intakes are used in water supply systems for several buildings in some spas. The goal of our study was to determine the activity concentration of radon in underground spring water consumed by inhabitants and tourists and to calculate annual effective doses due to this radionuclide consumption and inhalation. Measurements of radon were performed with the use of the liquid scintillation technique

A feasibility study of extraterrestrial disposal of radioactive waste is reported. This report covers the initial work done on only one part of the NASA study, that evaluates and compares possible space destinations and space transportation systems. The currently planned space shuttle was found to be more cost effective than current expendable launch vehicles by about a factor of 2. The space shuttle requires a third stage to perform the waste disposal missions. Depending on the particular mission, this third stage could be either a reusable space tug or an expendable stage such as a Centaur.

Non-linear behavior of public opinion on the issues regarding inhabitants' polls

2003-01-01

The observed change of public attitude around the time of inhabitants' poll in Japan was compared with model calculation to investigate its non-linear behavior. Two inhabitants' polls regarding nuclear issues, the approval and disapproval of the construction of Maki nuclear station, and of the MOX fuel use at Kashiwazaki-Kariwa nuclear station, were considered together with the poll on the reconstruction of the tenth weir in Yoshino river carried out in Tokushima. By using a mathematical model such that the individual attitude is mainly subject to two factors of the information environment and the mutual communication between the public, it was found that the change and the unification of public attitude around the time of inhabitants' poll can be interpreted as a manifestation of self-organization resulted from the cooperative phenomenon of those two factors. Moreover, it was also found that the abrupt change of public attitude just before the poll can be interpreted as a result of positive feedback of the information environment formed by the various types of propaganda activities to the attitude change, though the extent of such non-linear effects differs from case to case.

James Webb Space Telescope (JWST) is the space-based observatory that will extend the knowledge gained by the Hubble Space Telescope (HST). Hubble focuses on optical and ultraviolet wavelengths while JWST focuses on the infrared portion of the electromagnetic spectrum, to see the earliest stars and galaxies that formed in the Universe and to look deep into nearby dust clouds to study the formation of stars and planets. JWST, which commenced creation in 1996, is scheduled to launch in 2018. It includes a suite of four instruments, the spacecraft bus, optical telescope element, Integrated Science Instrument Module (ISIM, the platform to hold the instruments), and a sunshield. The mass of JWST is approximately 6200 kg, including observatory, on-orbit consumables and launch vehicle adaptor. Many challenges were overcome while providing the electrical and electronic components for the Goddard Space Flight Center hardware builds. Other difficulties encountered included developing components to work at cryogenic temperatures, failures of electronic components during development and flight builds, Integration and Test electronic parts problems, and managing technical issues with international partners. This paper will present the context of JWST from a EEE (electrical, electronic, and electromechanical) perspective with examples of challenges and lessons learned throughout the design, development, and fabrication of JWST in cooperation with our associated partners including the Canadian Space Agency (CSA), the European Space Agency (ESA), Lockheed Martin and their respective associated partners. Technical challenges and lessons learned will be discussed.

Inquest of Daugavpils' region pointed to a big anxiety for ecological danger of Ignalina NPP by inhabitants and experts. Absolute majority of respondents (73-78% inhabitants and 68-82% experts) apprehend the NPP as very dangerous and dangerous. More than half of respondents apprehend the dangerous increased during last two-three years. It is because no one has a good reference about situation, because tragic al Chernobyl NPP burst was on. The anxiety increases if the respondent lives nearer of NPP. Inhabitants of Daugavpils and it's region wants the better reference about situation, about future of Ignalina NPP after 2010 year, about securities means in case of NPP burst. (author)

The plant root defines the interface between a multicellular eukaryote and soil, one of the richest microbial ecosystems on Earth. Notably, soil bacteria are able to multiply inside roots as benign endophytes and modulate plant growth and development, with implications ranging from enhanced crop productivity to phytoremediation. Endophytic colonization represents an apparent paradox of plant innate immunity because plant cells can detect an array of microbe-associated molecular patterns (also known as MAMPs) to initiate immune responses to terminate microbial multiplication. Several studies attempted to describe the structure of bacterial root endophytes; however, different sampling protocols and low-resolution profiling methods make it difficult to infer general principles. Here we describe methodology to characterize and compare soil- and root-inhabiting bacterial communities, which reveals not only a function for metabolically active plant cells but also for inert cell-wall features in the selection of soil bacteria for host colonization. We show that the roots of Arabidopsis thaliana, grown in different natural soils under controlled environmental conditions, are preferentially colonized by Proteobacteria, Bacteroidetes and Actinobacteria, and each bacterial phylum is represented by a dominating class or family. Soil type defines the composition of root-inhabiting bacterial communities and host genotype determines their ribotype profiles to a limited extent. The identification of soil-type-specific members within the root-inhabiting assemblies supports our conclusion that these represent soil-derived root endophytes. Surprisingly, plant cell-wall features of other tested plant species seem to provide a sufficient cue for the assembly of approximately 40% of the Arabidopsis bacterial root-inhabiting microbiota, with a bias for Betaproteobacteria. Thus, this root sub-community may not be Arabidopsis-specific but saprophytic bacteria that would naturally be found

Lin Zhang; Zhu Ying; Kalabegishvili, Tamaz L.; Tsibakhashvili, Nelly Y.; Holman, Hoi-Ying

2006-01-01

Basalt-inhabiting bacteria isolated from polluted basalts have been demonstrated to be able to tolerate moderate to high concentrations of chromium oxyanions such as chromate. Previous results have shown that macromolecules outside the cell wall of bacteria may play an important role in this survival ability. In this paper, Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) were applied to study the chromate-induced morphological changes in chromate-resistant basalt-inhabiting Arthrobacter K-2 and K-4, which were isolated from the Republic of Georgia. The surfaces of both strains changed in the presence of chromate. TEM thin sections show that chromate stimulates the appearance of bacteria capsular polysaccharide outside the cell wall, although the chromate concentration does not have a strong effect on the capsular thickness. These results, in conjunction with those reported earlier, provide direct evidence to show that capsular polysaccharides of the bacteria play very important role for the reduction and localization of chromate

Municipal Competition for Inhabitants under Population Decrease. Zusammenfassung: Kommunale Konkurrenz um Einwohner bei Bevölkerungsrückgang

Directory of Open Access Journals (Sweden)

Peter Friedrich

2014-12-01

Full Text Available The shrinking population during the break-down, adaptation and recovery phase in Estonian social and political development enforces municipal competition among the municipalities. Competition for inhabitants is embedded in regional competition showing horizontal and vertical competition relations. Inhabitants’ competition prevails indirectly through municipal business promotion competition and directly through competition for inhabitants. The competition shows three phases. A phase concerns zoning and long-term planning; a second one refers to negotiations with settlement firms and short-term actions to attract inhabitants followed by a phase of revisions of zoning and measures. The oligopolistic industrial zoning model of business promotion policy points to the consequences of horizontal municipal competition also on population. Vertical influences on business promotion policy demonstrate a game-theoretic example of intergovernmental intervention from higher government on zoning. The negotiation phase in business promotion policy is modelled by a bilateral monopoly model between a municipality and a settlement firm. Horizontal regional competition highlights the implications on inhabitants’ competition. An oligopoly model of direct inhabitant competition concerns the zoning in particular for housing. Furthermore, a model of public enterprise service and fee formation and of horizontal public firm competition shows inhabitants’ competition in the second phase. Forms of inhabitant competition concerning suburbanisation and using public debt, revenues such as taxes, fees and expenditures are mentioned. Finally, follows a discussion of possible instruments to regulate inhabitant competition.

The purpose of this research is to clarify people's cognitive structure of nuclear energy, and to analyze how the cognitive structure varies with inhabiting areas, genders, and knowledge of nuclear energy. For this purpose, we carried out questionnaire survey of perception of nuclear energy in the urban areas and nuclear power plants (NPP) siting areas. After collecting data, we defined 8 categories in terms of respondents' inhabiting areas, genders, and knowledge, and applied factor analysis to each category's data. Consequently, we found 4 cognitive factors of nuclear: 'trust in the authorities', 'utility of nuclear power generation', 'benefit for NPP siting areas', and 'risk perception about nuclear technology', regardless of the respondents' inhabiting areas, genders, and knowledge. In addition, when the respondents assess many perceptions of nuclear energy, respondents living in urban areas tend to regard 'trust in the authorities' as important, while respondents living in NPP siting areas tend to take into consideration of risk perception about nuclear technology'.

and a path to our common future. But for humanity to embark on this path, we need to understand ourselves in a new environment. As such, an understanding of the biological consequences of and opportunities in space flight is essential. In this, the first volume of a joint U.S./Russian series on space biology and medicine, we describe the current status of our understanding of space and present general information that will prove useful when reading subsequent volumes. Since we are witnesses to the beginning of a new era of interplanetary travel, a significant portion of the first volume will concentrate on the physical and ecological conditions that exist in near and outer space, as well as heavenly bodies from the smallest ones to the giant planets and stars. While space exploration is a comparatively recent endeavor, its foundations were laid much more than 30 years ago, and its history has been an eventful one. In the first part of this volume, Rauschenbach, Sokolskiy, and Gurjian address the "Historical Aspects of Space Exploration" from its beginnings to a present-day view of the events of the space age. The nature of space itself and its features is the focus of the second section of the volume. In the first chapter of the part, "Stars and Interstellar Space," the origin and evolution of stars, and the nature of the portions of space most distant from Earth are described by Galeev and Marochnik. In Chapter 2, Pisarenko, Logachev, and Kurt in "The Sun and Interplanetary Space" bring us to the vicinity of our own solar system and provide a description and discussion of the nearest star and its influence on the space environment that our Earth and the other planets inhabit. In our solar system there are many fascinating objects, remnants of the formation of a rather ordinary star in a rather obscure portion of the galaxy. Historical accident has caused us to be much more curious (and knowledgeable) about "The Inner Planets of the Solar System" than about any of

The aim of this survey was to compare Chinese natives and foreign inhabitants in Chengdu, China, with respect to: (1) attitudes towards dental appearance, (2) subjective orthodontic treatment need, and (3) the main factors influencing orthodontic treatment need. A total of 522 subjects, including 227 foreign inhabitants and 295 Chinese natives in Chengdu participated in the survey. A simple random sampling method was adopted and a face-to-face interview was conducted at some public sites using a questionnaire. Data was entered by two persons synchronously using Epidata 3.0, and SPSS 13.0 was used to analyze these data. 89.0% of foreign inhabitants were satisfied with their teeth compared to only 46.8% of Chinese natives. Females were more dissatisfied with their teeth than males. Chinese natives put improving appearance as the top priority (55.9%) for seeking orthodontic treatment; however, in foreign inhabitants, the main reason for seeking treatment was to improve masticatory function (44.1%), followed by "to be pretty" (35.2%). The importance of well-aligned teeth and self-perception of psychosocial impact of malocclusion were the same two main factors influencing subjective orthodontic treatment need (P different (P differences in orthodontic treatment motives between the two target groups. (3) There were differences in subjective orthodontic treatment needs between foreign inhabitants and Chinese natives. However, the prominent influential factors were almost the same. There may be benefit to understanding subjective orthodontic needs of different races.

Full Text Available Global warming with its attendant consequences such as extreme heat, natural disasters, poor air quality and allergens has increased health problems. The risk of injury, illness and resulting death among inhabitants are expected to be frequent and intense especially in areas with heavy industrial presence. The current low level of literacy and the socio-economic situation of Nigerians could be responsible for their low consciousness of this unpreventable changes in our climate in one hand and lack of willingness on the part of people to seek environmental health and safety information on the causes, effect and how to mitigate global warming on the other hand. This study focuses on assessment of knowledge and awareness of causes, effects and mitigating measures of global warming among inhabitants of industrial areas of Ibadan southwestern Nigeria. In this descriptive survey, purposive sampling technique was used to select 200 respondents from among the inhabitants of this area. A questionnaire with reliability co-efficient (r of 0.78 was used for data collection. Two research questions were answered and three hypotheses tested at 0.05 level of significance. Statistical methods such as Chi-square, frequency count, simple percentage and pie chart were used for data analysis. Results showed that only 20% had 34.0% had negative attitude while 81 (40.5% were indifferent, all the three hypotheses were rejected. Consequently, it was deduced that respondents have significant knowledge of global warming. In recommendation, people’s environmental health seeking behaviour should be promoted through multidisciplinary and interdisciplinary research and the development of inclusive environmental health and safety intervention strategies.

Gudiksen, P.H.; Crites, T.R.; Robison, W.L.

1976-01-01

To evaluate the potential radiation doses that may be received by the returning Bikinians, we surveyed the residual radioactivity on Bikini and Eneu Islands in June of 1975. An integral part of the survey included measurements of gamma-ray exposure rates which are used to estimate external gamma-ray doses. The survey showed that on Bikini Island the rates are highly variable: values near the shores are generally of the order of 10 to 20 μR/h, while those within the interior average about 40 μR/h with a range of roughly 30 to 100 μR/h. Eneu Island, however, is characterized by more or less uniformly distributed gamma radiation levels of less than 10 μR/h over the entire island. These data, in conjunction with population statistics and expected life styles, allowed us to estimate the potential external gamma-ray doses associated with proposed housing locations along the lagoon road and within the interior portions of Bikini Island as well as along the lagoon side of Eneu Island. As expected, living on Eneu Island results in the lowest doses: 0.12 rem during the first year and 2.9 rem during 30 years. The highest values, 0.28 rem during the first year and 5.9 rem over 30 years, may potentially be received by inhabitants living within the interior of Bikini Island. Other options under consideration produce intermediate values

Planetary Space Weather Service: Part of the the Europlanet 2020 Research Infrastructure

Science.gov (United States)

Grande, Manuel; Andre, Nicolas

2016-07-01

Over the next four years the Europlanet 2020 Research Infrastructure will set up an entirely new European Planetary Space Weather service (PSWS). Europlanet RI is a part of of Horizon 2020 (EPN2020-RI, http://www.europlanet-2020-ri.eu). The Virtual Access Service, WP5 VA1 "Planetary Space Weather Services" will extend the concepts of space weather and space situational awareness to other planets in our Solar System and in particular to spacecraft that voyage through it. VA1 will make five entirely new 'toolkits' accessible to the research community and to industrial partners planning for space missions: a general planetary space weather toolkit, as well as three toolkits dedicated to the following key planetary environments: Mars (in support ExoMars), comets (building on the expected success of the ESA Rosetta mission), and outer planets (in preparation for the ESA JUICE mission to be launched in 2022). This will give the European planetary science community new methods, interfaces, functionalities and/or plugins dedicated to planetary space weather in the tools and models available within the partner institutes. It will also create a novel event-diary toolkit aiming at predicting and detecting planetary events like meteor showers and impacts. A variety of tools (in the form of web applications, standalone software, or numerical models in various degrees of implementation) are available for tracing propagation of planetary and/or solar events through the Solar System and modelling the response of the planetary environment (surfaces, atmospheres, ionospheres, and magnetospheres) to those events. But these tools were not originally designed for planetary event prediction and space weather applications. So WP10 JRA4 "Planetary Space Weather Services" (PSWS) will provide the additional research and tailoring required to apply them for these purposes. The overall objectives of this Joint Research Aactivities will be to review, test, improve and adapt methods and tools

In this study by Multi-parameter flow cytometry, immunologic analyze is performed on peripheral blood, NK cells, most effective cells in innate immune and the proportion of TCD8/TCD4 cells that is effective in cellular immune system will be determined. Lysosomal-associated membrane protein-1 (LAMP-1 or CD107a) is used as a functional marker for the identification of natural killer cell activity. Immune surveillance and immune system role in tumoral defense in Ramsar inhabitants will be determined. Radiation dose rate in Talesh mahalle is very high and was many times greater than Chaparsar (another region in Ramsar). Immune surveillance and immune system role in tumoral defense in Talesh mahalle inhabitants will be compared to Chaparsar inhabitants. If this doesn't have significant difference, we should think about some other aspects such as free radical scavengers that will study later

Experiencing the relationship between architectural space and the major space phobias

Directory of Open Access Journals (Sweden)

Dana Pop

2015-12-01

Full Text Available During the past decades there was a noticeable effervescence characterising the space-psychology related studies. These studies established a connection between the characteristics of the environment and behaviour. Thus, this paper would like to join this field of research. Consequently, the first issue raised is whether architecture is about a space in itself, or whether it is about perception, of a mental representation. A second issue is whether a space has qualities of its own, or whether its characteristics depend on the subjectivity of the perceptual process. This hypothesis generated an entire field of research, which disputes the differences between space and place. The last issue would be the role played by architecture in the context of the space-place-perception discussion. Thus, architecture finds itself in the middle of this debate, being the instrument which carves the environment we inhabit. In order to provide a practical answer to this last question, the paper bases its conclusions on the results obtained through an experiment. This experiment tested certain situations in which the natural adaptation process has been short-circuited. These are phobic reactions. Thus, the paper wishes to lay the first theoretical ‘brick’ at the foundation of an interdisciplinary research project between architecture, psychology, sociology and virtual reality.

A group of 172 rural inhabitants from eastern Poland (68 males and 104 females, mean age 49.0 ± 12.0 years) was examined for the presence of antibodies against Echinococcus granulosus and Echinococcus multilocularis. A population of 38 healthy urban dwellers from the city of Lublin (17 males and 21 females, mean age 36.2 ± 9.6 years) were examined as a control group. Sera of 22 rural inhabitants (12.8%) reacted positively to Echinococcus granulosus hydatid fluid antigen in the screening test. A cross-reactivity was observed with two serum samples that tested positive in ELISA for E. granulosus. Three serum samples were tested positive for E. multilocularis using the Em2plus ELISA assay and also positive for Western blot. None of the members of control group showed the presence of a seropositive reaction to Echinococcus spp. The reactivity to Echinococcus spp. among rural inhabitants decreased with age and this correlation was statistically significant (R = -0.197151, p = 0.009535). The percentage of positive findings was the highest (50.0%) in the youngest age group (14-20). No significant correlations were found between responses to interview questions (possession of domestic and farm animals, contact with wild animals, eating unwashed berries, drinking unboiled water) and the presence of seropositive reactions to Echinococcus spp. The presented results seem to indicate that echinococcosis is still a current problem in Poland that should not be neglected and, moreover, indicates the need for improvement in the routine laboratory diagnostics of Echinococcus spp. by standardizing the ELISA and Western blot tests.

The purpose of the present contribution is to describe the prevalence of nervios through self-report, to identify psychological and somatic symptoms associated with nervios, and to report the comorbidity of nervios with mood and anxiety disorders among Mexican rural-origin adults. The data reported here were collected as part of a larger project, whose aims were to determine the prevalence of selected mental health problems, their sociocultural manifestation and interpretation, and the utilization of mental health services among the inhabitants of rural communities in Mexico. A multi-stage, stratified, random sample of two regions in Mexico was obtained. The total number of participants used in the analyses was 942 adults: 441 men and 501 women. We found a prevalence of nervios of 15.5% in the general population. When analyzed by sex, women had a significantly higher prevalence (20.8%) of this condition than men (9.5%). Also, all the somatic and psychological symptoms associated with nervios had a higher prevalence among women than men.

The American Nuclear Society (ANS) has seen an aspect of the universe where nuclear technology is the best energy source available for power, transportation, etc. The National Aeronautics and Space Administration (NASA) has been exploiting this aspect of the universe by sending machines and humans into it and exploring, colonizing, industrializing, developing, inhabiting, etc. Space is the final frontier, and nuclear technology is the best suited for today's or the next century's space exploration and development. Many aspects of nuclear technology and its uses in space will be needed. ANS encompasses these and many more aspects of nuclear technology, and all have some role to play in the exploration and development of space. It should be ANS's intent to be an advisory body to NASA on the nuclear aspects of space exploration

Slum inhabitants' perceptions and decision-making processes related to an innovative sanitation service: evaluating the Blue Diversion Toilet in Kampala (Uganda).

2015-01-01

The inadequate provision of sanitation in informal urban settlements, also known as slums, continues to be an important issue. New technologies and services are being designed to solve this problem. However, the history of failed sanitation programmes and projects highlights a lack of understanding of how slum inhabitants decide on investing in such products and services. In this paper, we gather perspectives from potential clients and investigate how slum inhabitants (1) perceive the current situation and whether they desire improvements of sanitation, (2) how they evaluate a new toilet that is still in development, and how (3) social processes and (4) constraints affect decisions. Data were collected through interviewing 1538 people within a general household survey. People using shared and public latrines desire an improvement of their sanitation facilities. The lack of water for washing is perceived by residents as a the biggest problem when accessing current latrines. The new toilet was mostly evaluated positively: people like it, expect large health benefits from it and it complies with cultural norms. However, people also expect some problems with the functioning of the toilet and expect opposition to pay for the service, due to the high costs and a lack of space to set up new toilets.

The Measurable and the Real Quality of Life in the City. Urban regeneration as a technological correlation of resources, spaces and inhabitants

Filippo Angelucci

2015-11-01

Full Text Available This essay looks at urban regeneration beginning from the notion of the exclusive qualities of the contemporary city: selective, closed, introspective, and inaccessible. Focusing on the tactical/metadesign phase of the urban regeneration process and referring to the paradigms of resilience and bio-psycho-social inclusion, the paper proposes a technological design vision to recompose the qualities of the ‘common good’ known as the city into an inclusive, open, communicative and accessible reality. Operating through technological-environmental interfaces and need-based/ enabling macro-requirements, the paper considers the urban system as an inhabitable organism characterised by differences, tensions and balances between the apparatuses of the city, within a matrix of widespread quality.

After the accident of the Fukushima Daiichi Nuclear Power Plant, enormous amount of waste contaminated by radioactive cesium has been produced. Burned ash that contained radiocesium ( 137 Cs) more than 8,000 Bq/kg will be stored at the not-yet-located final deposit. Until the final deposit is finally constructed, however, the radioactive ash should be stored safely at temporal deposits. Inhabitants briefing sessions for locating the temporal deposits are held at many places in the east Japan. But, they met difficulty in establishing smooth communication between citizens and the administrations. In this paper, I classify the questions arose from citizens at the inhabitants briefing session at Tokatsu area, Chiba prefecture, and discuss what role could scientists and science communicators play at this session. In addition, I classified the voices of inhabitants reported in the newspapers and discuss the media bias. (author)

For the last 25 years, every two to three years the Conferencia Latinoamericana de Geofísica Espacial (COLAGE) is held in one of the Latin American countries for the purpose of promoting scientific exchange among scientists of the region and to encourage continued research that is unique to this area of the world. At the more recent conference, the community realized that many individuals both within and outside Latin America have contributed greatly to the understanding of the space sciences in this area of the world. It was therefore decided to assemble a Special Issue Space and Geophysical Physics related to Latin America, presenting recent results and where submissions would be accepted from the world wide community of scientists involved in research appropriate to Latin America. Because of the large number of submissions, these papers will be printed in two separate issues; this is Part 1. These papers show the wide variety of research, both theoretical and applied, that is currently being developed in the Sub-Continent.

Full Text Available The topic of this issue is PUBLIC SPACES. It is familiar and clear to every citizen. The streets and courtyards as childhood experiences remain with us forever. And these are the places where we come with our parents at weekends, where we meet friends, where we have dates and where we already come for a walk with our children.The history of public spaces is long and captivating. It was the main city squares where the most important events took place in history. The Agoras of Ancient Greece and the Roman Forums, the squares of Vatican, Paris and London, Moscow and Saint Petersburg… Greve, Trafalgar, Senate, Palace, Red, Bolotnaya – behind every name there is life of capitals, countries and nations.Public spaces, their shapes, image and development greatly influence the perception of the city as a whole. Both visitors and inhabitants can see in public spaces not only the visage but the heart, the soul and the mind of the city.Unfortunately, sometimes we have to prove the value of public spaces and defend them from those who consider them nothing but a blank space, nobody’s land destined for barbarous development.What should happen to make citizens perceive public spaces as their own and to make authorities consider development and maintenance of squares and parks their priority task against the  background of increasing competition between cities and the fight for human capital? Lately they more often say about “a high-quality human capital”. And now, when they say “the city should be liveable” they add “for all groups of citizens, including the creative class”.

This study analyses the different parts of the upper airway space and the changes in hyoid position. The results provide a clinical reference for developing timely and effective treatment programmes for patients with mandibular fractures caused by maxillofacial trauma. Standard X-cephalometric measurements of the lateral skull of 210 subjects were taken. The subjects were divided into four fracture groups: condylar, mandibular angle, mandibular body, and parasymphyseal. The radiographs of the mandibular fracture groups were compared with the normal occlusion group to analyse the upper airway space and the changes in hyoid position. Different types of fractures have different effects on the upper airway space. Bilateral mandibular body fracture and the parasymphyseal fracture have a significant influence on the lower oropharyngeal and laryngopharyngeal airway spaces, with serious obstructions severely restricting the ventilatory function of patients. Fractures at different parts of the mandibular structure are closely related to the upper airway and hyoid position.

Full Text Available Footprint 19 focuses on the more recent roles of architecture in the contemporary spaces of conflict. Departing from a spatial understanding of geopolitical, climatological and economical conflicts, the various contributions highlight the large scale and phenomenal transitions in the physical world and in society by extrapolating, through examples, the abundance of relations that can be traced between conflict, territory and architecture. Conflict areas often prove to be fertile grounds for innovation and for the emergence of new spatial forms. The issue reports on the state of perpetual global unrest in architecture through a series of articles and case studies that highlight the consequences of conflicts in the places and spaces that we inhabit. In the introduction, these are discussed as an interlinked global reality rather than as isolated incidents. In doing so, the contemporary spaces of conflict are positioned in the context of emerging global trends, conditions, and discourses in the attempt to address their indicative symptoms while reflecting on their underlying causes.

2017-12-01

Full Text Available Zilla spinosa is one of the dominated woody perennial shrubs widespread in the Egyptian Red sea coastal desert, belonging to family Brassicacea. Z. spinosa is used as a folk medicine and for heating by local people. Z. spinosa inhabits arid habitats exposed to adverse climatic changes which influence the production of the bioactive natural products. The natural secondary products have significant importance for plant acclimatization to the arid habitats beside their significant practical application in medicinal, nutritive and industrial purposes. The accumulation levels of some natural products including phenols, tannins, glucosinolates, flavonoids, saponins, proanthocyanidins and cardiac glycosides were measured in Z. spinosa inhabiting different locations of Wadi Hagul during spring and summer seasons. The results of the current study showed that Z. spinosa grown in the adverse environment has adapted to cope with extreme temperature, water deficit and geoclimate changes especially in summer, by enhancing the accumulation of some antioxidant compounds including phenols, tannins, glucosinolates, flavonoids, saponins, cardiac glycosides, concomitant with increments in the total antioxidant capacity and PAL activity. Consequently, Z. spinosa shrubs inhabiting the arid environment is a promising new source of saponins, glucosinolates, cardiac glycosides, phenols and flavonoids which could participate in drug development and exploration of alternative strategies to increase productivity of wild plants.

2008-05-01

Full Text Available Abstract Consumption of greens is a major source of vitamins and micro-nutrients for people using only vegetarian diets rich in carbohydrates. In remote rural settlements where vegetable cultivation is not practiced and market supplies are not organized, local inhabitants depend on indigenous vegetables, both cultivated in kitchen gardens and wild, for enriching the diversity of food. Knowledge of such foods is part of traditional knowledge which is largely transmitted through participation of individuals of households. A total of 123 households in six villages of Nanda Devi Biosphere Reserve buffer zone was surveyed using a schedule to assess the knowledge, availability and consumption pattern of wild leafy vegetables. Quantity estimations were done using regular visits with informants from 30 sample households of the six study villages during the collections. Monetization was used to see the value of wild leafy vegetables harvested during a year. The diversity of wild leafy vegetables being use by the local inhabitants is 21 species belonging to 14 genera and 11 families. This is far less than that being reported to be used by the communities from Western Ghats in India and some parts of Africa. Irrespective of social or economic status all households in the study villages had the knowledge and used wild leafy vegetables. The number of households reported to consume these wild leafy vegetables is greater than the number of households reporting to harvest them for all species except for Diplazium esculentum and Phytolacca acinosa. The availability and use period varied for the species are listed by the users. The study indicated that the knowledge is eroding due to changing social values and non participation of younger generation in collection and processing of such wild leafy vegetables.

DISTINGUISHING A HYPOTHETICAL ABIOTIC PLANET–MOON SYSTEM FROM A SINGLE INHABITED PLANET

International Nuclear Information System (INIS)

Li, Tong; Tian, Feng; Wei, Wanjing; Huang, Xiaomeng; Wang, Yuwei

2016-01-01

It has recently been suggested that an exomoon with a CH 4 atmosphere, orbiting an abiotic Earth-mass planet with an O 2 -rich atmosphere, can produce a false positive biosignature at a low–moderate spectral resolution (R = λ/Δλ ≤ 2000). If this were true, inferring the presence of life on exoplanets will be beyond our reach in the next several decades. Here we use a line-by-line radiative transfer model to compute the relevant reflection spectrum between 1 and 3.3 μm. We show that it is possible to separate the combined spectra of such planet–moon systems from an inhabited planet by multiple-band NIR observations. We suggest that future observations near the 2.3 μm CH 4 absorption band at a resolution of 100 and an SNR of 10 or more may be a good way to distinguish an abiotic planet–moon system from a inhabited single planet

Decapod is one of the cryptic fauna associated with coral reefs, which play an important role and accounts for a major part of the biodiversity in the reef ecosystem. However, this biodiversity is largely overlooked and assessment regarding this biodiversity has not been conducted thoroughly due to lack of resources and the difficulties of sample collection. This research used semi-quantitative sampling methods to assess the community structure of decapod species inhabit dead Pocillopora sp. in Pemuteran, Bali. Two dead coral head of Pocillopora sp. were used as pilot study and sampled at the 8-12 m depth. All decapod found were collected and identify into family level. The result showed 214 decapods found consisting 12 families, with Xanthidae as the most abundant family. Community Index which consisting diversity, uniformity, and dominancy, indicated medium diversity, stable uniformity, and low dominancy of decapod community. This result also indicated no dominancy between families of decapod. Meanwhile, Species Density Index showed the value of 84.58 ± 2.04 individual per m3, with mean diversity of 7.05 ± 2.04 individual per m3 for each family.

Myth-free space advocacy part I-The myth of innate exploratory and migratory urges

Science.gov (United States)

Schwartz, James S. J.

2017-08-01

This paper discusses the ;myth; that we have an innate drive to explore or to migrate into space. Three interpretations of the claim are considered. According to the ;mystical interpretation,; it is part of our ;destiny; as humans to explore and migrate into space. Such a claim has no rational basis and should play no role in rationally- or evidence-based space advocacy. According to the ;cultural interpretation,; exploration and migration are essential features of human culture and society. These are not universal features because there are cultures and societies that have not encouraged exploration and migration. Moreover, the cultures that have explored have seldom conducted exploration for its own sake. According to the ;biological interpretation; there is a psychological or genetic basis for exploration or migration. While there is limited genetic evidence for such a claim, that evidence suggests that genes associated with exploratory behavior were selected for subsequent to migration, making it unlikely that these genes played a role in causing migration. In none of these senses is it clearly true that we have an innate drive to explore or migrate into space; and even if we did it would be fallacious to argue that the existence of such a drive justified spaceflight activities.

In their research and professional practice they inhabit the ‘space between’: the space between languages, the space between cultures, and the space between academic disciplines. While many of our contributors are located in the Australian university system, we also have contributors from outside that system, as well as contributors who are theorising disparate sites for the negotiation of difference. The most exciting aspect of the papers presented here is the ability to move between the spheres of cultural theory and the everyday. Analytical techniques originally developed for literary and cultural analysis are brought to bear on the texts and practices of everyday life. The loci for these investigations include the classroom, the police station, the streets, local government and the university itself. The practices examined include translating and interpreting, language teaching, academic writing, literary production and critique, language planning and small business and shadow economies. The academic disciplines drawn on include theoretical and applied linguistics, discourse analysis, language teaching pedagogy, policy studies, cultural studies, literary studies, political science, gender studies and postcolonial theory.

Republic of Kazakhstan is ranked as the world's leading uranium ore reserves. About 25% of the world's proven uranium ore reserves occur here. Strategy of study concerning ecology effects conditioned by ionizing radiation includes as one main element an analysis of genetic processes in natural populations and ecosystems. Therefore analysis of cytogenetic effects of murine rodents inhabiting in influence zones of uranium-mining regions is one of the most important elements of radio-bio-ecological monitoring and are not completed so far. In habitat of murine rodents in influence zone of Stepnogorsk Mining-Chemical Complex tailing it is shown that gamma radiation equivalent dose rate and beta-particle flux density exceed from 6 to 15 times check measurements. In soil, plant, and water samples the activity of radionuclides like 238 U, 226 Ra, 232 Th and 210 Pb exceeds the testing level from 2 to 52 times. Dose of ionizing radiation absorbed by murine rodents inhabited in radioactive contaminated areas exceeds from 10 to 19 times the one absorbed by control animals. Big Jerboa (Allactaga major Kern) inhabited nearby of Stepnogorsk Mining-Chemical Complex tailing has rate of occurrence of cells with hypo diploidy, and hyper diploidy in hematopoietic tissue which correspondingly 1,85 and 3,5 times exceeds the control level; and this factor of Jerboa (Allactaga saltator Eversman) is correspondingly 1,7 and 4,1 times higher than control level. Rate of occurrence of cells with polyploidy in Big Jerboa (Allactaga major Kern) from radioactively contaminated areas is 2,7 times higher than in control animal; and this factor of Jerboa (Allactaga saltator Eversman) by 6,4 times exceeds control level. Levels of chromosomal rearrangements of Big Jerboa (Allactaga major Kern) from trail and control areas are 3,39±0,60% and 0,60±0,19% correspondently; and these factors of Jerboa (Allactaga saltator Eversman) are 4,63±0,91% and 1,22±0,37%, correspondently which confirms existence

Just in Time in Space or Space Based JIT

Our satellite systems are mega-buck items. In today's cost conscious world, we need to reduce the overall costs of satellites if our space program is to survive. One way to accomplish this would be through on-orbit maintenance of parts on the orbiting craft. In order to accomplish maintenance at a low cost I advance the hypothesis of having parts and pieces (spares) waiting. Waiting in the sense of having something when you need it, or just-in-time. The JIT concept can actually be applied to space processes. Its definition has to be changed just enough to encompass the needs of space. Our space engineers tell us which parts and pieces the satellite systems might be needing once in orbit. These items are stored in space for the time of need and can be ready when they are needed -- or Space Based JIT. When a system has a problem, the repair facility is near by and through human or robotics intervention, it can be brought back into service. Through a JIT process, overall system costs could be reduced as standardization of parts is built into satellite systems to facilitate reduced numbers of parts being stored. Launch costs will be contained as fewer spare pieces need to be included in the launch vehicle and the space program will continue to thrive even in this era of reduced budgets. The concept of using an orbiting parts servicer and human or robotics maintenance/repair capabilities would extend satellite life-cycle and reduce system replacement launches. Reductions of this nature throughout the satellite program result in cost savings.

Organochlorine pesticides have been used in Mexico in malaria control programs and against ectoparasites. The objective of this study was to compare the levels of organochlorine pesticides: HCB, α-β-γ-HCH, pp'-DDE, op'-DDT and pp'-DDT in adipose tissue of female inhabitants from three Mexican states: Veracruz, Puebla and Tabasco. Data analyses indicated higher β-HCH levels in Puebla inhabitants. When comparing the mean values of the pp'-DDE concentrations among the three states, no statistically significant differences were noted. A trend of increasing concentrations of op'-DDT from Veracruz to Puebla and Tabasco was observed. Significantly higher pp'-DDT concentrations in Veracruz as compared to Puebla and Tabasco were determined. Using factorial analysis of three age categories (>30, 31-50, pesticide concentrations increases with age of participants, indicating time of exposure as a principal factor of organochlorine pesticides accumulation in adipose tissue.

Full Text Available Brazil has reported more than 1,600 cases of hantavirus cardiopulmonary syndrome (HPS since 1993, with a 39% rate of reported fatalities. Using a recombinant nucleocapsid protein of Araraquara virus, we performed ELISA to detect IgG antibodies against hantavirus in human sera. The aim of this study was to analyze hantavirus antibody levels in inhabitants from a tropical area (Amazon region in Rondônia state and a subtropical (Atlantic Rain Forest region in São Paulo state, Brazil. A total of 1,310 serum samples were obtained between 2003 and 2008 and tested by IgG-ELISA, and 82 samples (6.2%, of which 62 were from the tropical area (5.8% and 20 from the subtropical area (8.3%, tested positive. Higher levels of hantavirus antibody were observed in inhabitants of the populous subtropical areas compared with those from the tropical areas in Brazil.

The main aim of this study was to determine and evaluate urinary excretion of uranium in the general public of the Czech Republic. This value should serve as a baseline for distinguishing possible increase in uranium content in population living near legacy sites of mining and processing uranium ores and also to help to distinguish the proportion of the uranium content in urine among uranium miners resulting from inhaled dust. The geometric mean of the uranium concentration in urine of 74 inhabitants of the Czech Republic was 0.091 mBq/L (7.4 ng/L) with the 95% confidence interval 0.071–0.12 mBq/L (5.7–9.6 ng/L) respectively. The geometric mean of the daily excretion was 0.15 mBq/d (12.4 ng/d) with the 95% confidence interval 0.12–0.20 mBq/d (9.5–16.1 ng/d) respectively. Despite the legacy of uranium mines and plants processing uranium ore in the Czech Republic, the levels of uranium in urine and therefore, also human body content of uranium, is similar to other countries, esp. Germany, Slovenia and USA. Significant difference in the daily urinary excretion of uranium was found between individuals using public supply and private water wells as a source of drinking water. Age dependence of daily urinary excretion of uranium was not found. Mean values and their range are comparable to other countries, esp. Germany, Slovenia and USA. - Highlights: • Urinary uranium content of the inhabitants was experimentally determined. • Significant difference was found between inhabitants and uranium miners. • Higher uranium urinary content was found at users of private wells. • Dependence of urinary content on the age was not found. • The mean value and range of uranium daily excretion is similar to other countries.

We explored the abundance of antibiotic-resistant Escherichia coli among migratory birds at remote sites in Alaska and used a comparative approach to speculate on plausible explanations for differences in detection among species. At a remote island site, we detected antibiotic-resistant E. coli phenotypes in samples collected from glaucous-winged gulls (Larus glaucescens), a species often associated with foraging at landfills, but not in samples collected from black-legged kittiwakes (Rissa tridactyla), a more pelagic gull that typically inhabits remote areas year-round. We did not find evidence for antibiotic-resistant E. coli among 347 samples collected primarily from waterfowl at a second remote site in western Alaska. Our results provide evidence that glaucous-winged gulls may be more likely to be infected with antibiotic-resistant E. coli at remote breeding sites as compared to sympatric black-legged kittiwakes. This could be a function of the tendency of glaucous-winged gulls to forage at landfills where antibiotic-resistant bacterial infections may be acquired and subsequently dispersed. The low overall detection of antibiotic-resistant E. coli in migratory birds sampled at remote sites in Alaska is consistent with the premise that anthropogenic inputs into the local environment or the relative lack thereof influences the prevalence of antibiotic-resistant bacteria among birds inhabiting the area.

Ground-based space analog projects such as the NASA Extreme Environment Mission Operations (NEEMO) can be valuable test beds for evaluation of experimental design and hardware feasibility before actually being implemented on orbit. The International Space Station (ISS) is an closed-system laboratory that orbits 240 miles above the Earth, and is the ultimate extreme environment. Its inhabitants spend hours performing research that spans from fluid physics to human physiology, yielding results that have implications for Earth-based improvements in medicine and health, as well as those that will help facilitate the mitigation of risks to the human body associated with exploration-class space missions. ISS health and medical experiments focus on pre-flight and in-flight prevention, in-flight treatment, and postflight recovery of health problems associated with space flight. Such experiments include those on enhanced medical monitoring, bone and muscle loss prevention, cardiovascular health, immunology, radiation and behavior. Lessons learned from ISS experiments may not only be applicable to other extreme environments that face similar capability limitations, but also serve to enhance standards of care for everyday use on Earth.

In this study the neutron activation analysis (NAA) technique was applied to determine Ca and Mg in whole blood from inhabitants of Brazil for the purpose of establishing concentration ranges indicative of sex and age. The initiative to perform these measurements is related to the increase in heart disease. According to recent statistics from WHO, the average is one death due to heart attack in Brazil, every five minutes. The measures were performed considering lifestyle factors (non-smokers, non-drinkers and no history of toxicological exposure) of Brazilian inhabitants. A healthy group constituted of male (n = 94) and female (n = 84) blood donors, ages between 18 and 70 years and above 50 kg, was selected from the blood banks and hematological laboratories of Brazil. The influence of sex was also investigated considering several age ranges (18-29, 30-40, 41-50, >50 years). The results show significant differences when a comparison is made by sex and age and may be useful to identify or prevent clinical diseases. These results emphasize the need to perform periodic evaluation of Ca and Mg in blood. (author)

Low effect of young afforestations on bird communities inhabiting heterogeneous Mediterranean cropland

Directory of Open Access Journals (Sweden)

Juan S. Sánchez-Oliver

2015-12-01

Full Text Available Afforestation programs such as the one promoted by the EU Common Agricultural Policy have spread tree plantations on former cropland. These afforestations attract generalist forest and ubiquitous species but may cause severe damage to open habitat species, especially birds of high conservation value. We investigated the effects of young (<20 yr tree plantations dominated by pine P. halepensis on bird communities inhabiting the adjacent open farmland habitat in central Spain. We hypothesize that pine plantations located at shorter distances from open fields and with larger surface would affect species richness and conservation value of bird communities. Regression models controlling for the influence of land use types around plantations revealed positive effects of higher distance to pine plantation edge on community species richness in winter, and negative effects on an index of conservation concern (SPEC during the breeding season. However, plantation area did not have any effect on species richness or community conservation value. Our results indicate that the effects of pine afforestation on bird communities inhabiting Mediterranean cropland are diluted by heterogeneous agricultural landscapes.

The characteristics of open spaces between residential buildings have, as authors suppose, an impact on the sustainable development of urban areas. Spatial arrangement and accessibility of these spaces, the type and height of surrounding buildings, the quantity and character of greenery, and many more characteristics influence the quality of environment, and the quality of life of local residents. These and further characteristics of the open spaces between residential buildings influence the ecological stability of the area, its hygienic qualities, the intensity and way of using by various social groups, and also the prices of real estates. These qualities indicate the environmental, social and economic sustainability of the urban area. The proposed research methodology assessed specific indicators of sustainability within a range from 0 to 10 points. 5 points correspond to the general standard in the area, 0 points indicate degradation, and 10 points indicate the highest contribution to sustainable development. Observation methods, questionnaire survey, statistical analyses, and methods of measurement were used to determine the values of the given indicators. The paper analyses the impact of the open spaces between residential buildings on sustainability via the case studies performed in the Central European cities of Brno, Czech Republic and Vienna, Austria. Two forms of residential urban structures in the City of Brno in the Czech Republic were selected for the analysis: the closed courtyards in the urban block from the 19th century and the open spaces in the housing estates constructed under socialism in the 20th century. The question is, if the different forms of spaces between residential buildings influence the sustainability of urban area and satisfaction of inhabitants in different ways. A complementary case study in Vienna indicates that inhabitants of a housing estate in Vienna, as well as inhabitants of housing estates in Brno, highly appreciate the

As a part of the China-Japan cooperative research on the natural radiation epidemiology, we have carried out a dose-assessment study to evaluate the external to natural radiation in the high background radiation area (HBRA) of Yangjiang in Guangdong province and in the control area (CA) of Enping prefecture since 1991. Because of the difficulties in measuring the individual doses of all inhabitants directly by the personal dosimeters, an indirect method was applied to estimate the exposed dose rates from the environmental radiation dose rates measured by survey meters and the occupancy factors of each hamlet. An individual radiation dose roughly correlates with the environmental radiation dose and the life style of the inhabitant. We have analyzed the environmental radiation doses in the hamlets and the variation of the occupancy factors to obtain the parameters of dose estimation on the inhabitants in selected hamlets; Madi and the several hamlets of the different level doses in HBRA and Hampizai hamlet in CA. With these parameters, we made estimations of individual dose rates and compared them with those obtained from the direct measurement using dosimeters carried by selected individuals. The results obtained are as follows: (1) The environmental radiation dose rates are influenced by the natural radioactive nuclide concentrations in building materials, the age of the building and the arrangement of the houses in a hamlet. There existed a fairly large and heterogeneous distribution of indoor and outdoor environmental radiation. The indoor radiation dose rates were due to the exposure from the natural radioactive nuclides in the building materials and they were about twice higher than the outdoor radiation dose rates. This difference was not observed in CA. (2) The occupancy factor was affected by the age of individuals and the seasons of a year. Indoor occupancy factors were higher for infants and aged individuals than for other age groups. This lead to higher

Social space is various forms of spaces used by community in conducting social interaction. These kinds of spaces should be given more attention since they serve as catalyst in the implementation of good social cohesion in community. The effort includes giving concern toward their various implemented form. This concern will give benefits in the creation of resilient built environment. Kauman Kampong in Semarang, is an old urban kampong and still exist up until now. During its development, the inhabitant live and conduct their activities in good shape. Therefore this kampong is an appropriate place to learn and explore social spaces which is formed and utilized by the community who conduct their activities in this kampong. The aim of this research is to find out forms and typology of social space in Kauman Kampong in Semarang. Qualitative method is used in this research since the nature of this research is explorative. There are various social activities in Kauman Kampong in Semarang, such as religious, trading, and other social interaction, which have formed various social spaces. These social spaces have their own physical characteristics and with various intensity of activities. Based on collected data in field survey, the typology of social spaces that could be inferred are: permanent, temporary, and dynamic social space.

By applying instrumental neutron activation analysis techniques, a survey was carried out to determine the levels of a variety of trace element concentrations in human hair of the inhabitants of the Tokyo metropolitan area. A total of 202 scalp hair samples were collected from the inhabitants of the residential district in the western part of the Tokyo metropolitan area. The donors were divided into five age groups, ranging from pre-school age to sixty years and above. Each group consisted of twenty males and twenty or more females. The sampling method and washing procedure recommended by the IAEA Advisory Group on the applications of nuclear methods in environmental research were strictly followed. Irradiation of the samples was made in the Rikkyo University 100-kW TRIGA MARK II reactor. By using several combinations of irradiation time, cooling time and counting time, the following 37 elements were quantitatively analysed: Ag, Al, As, Au, Ba, Br, Ca, Cd, Ce, Cl, Co, Cr, Cu, Fe, Hg, I, K, La, Mg, Mn, Mo, Na, Ni, Rb, S, Sb, Sc, Se, Sm, Sn, Te, Ti, U, V, W and Zn. NBS standard reference orchard leaves and bovine liver were also analysed in the course of the hair analysis to assess the precision of the analytical techniques. (author)

SUICIDAL ATTEMPTS AMONG YOUNG RURAL INHABITANTS

Zdzisław Brzeski

2010-06-01

Full Text Available In recent years changes have been noted in the motivations for acute suicidal poisonings among young people from various environments, which are due to psychosocial changes both in the urban and rural environments. Suicidal attempts are accompanied – especially in the rural environment – by low social status, difficulties with adapting to a free market economy, emotional tension within the family, at school, in the environment of young people, addiction to alcohol, drug overuse, including psychotropes. Based on clinical material concerning rural inhabitants hospitalized due to suicidal poisonings, the authors performed the analysis of attitudes, motivations and causes of acute poisonings among the young rural population. Among rural adolescents who continued school or university education the dominant causes of undertaking a suicidal attempt were: adolescent period problems, conflicts within the family, conflicts with mates, and disappointment in love. Among young adults the motivations were as follows: difficulties with finding employment in the place of residence, conflicts within the family, overuse of stimulants, and sometimes states of depression during the period of aggravation of a disease.

2013-01-01

Full Text Available Background. Active modes of transport like walking and cycling have been shown to be valuable contributions to daily physical activity. The current study investigates associations between personal and neighbourhood environmental characteristics and active transport among inhabitants of Dutch deprived districts. Method. Questionnaires about health, neighbourhoods, and physical activity behaviour were completed by 742 adults. Data was analysed by means of multivariate linear regression analyses. Results. Being younger, female, and migrant and having a normal weight were associated with more walking for active transport. Being younger, male, and native Dutch and having a normal weight were associated with more cycling for active transport. Neighbourhood characteristics were generally not correlated with active transport. Stratified analyses, based on significant person-environment interactions, showed that migrants and women walked more when cars did not exceed maximum speed in nearby streets and that younger people walked more when speed of traffic in nearby streets was perceived as low. Among migrants, more cycling was associated with the perceived attractiveness of the neighbourhood surroundings. Discussion and Conclusion. Results indicated that among inhabitants of Dutch deprived districts, personal characteristics were associated with active transport, whereas neighbourhood environmental characteristics were generally not associated with active transport. Nevertheless, interaction effects showed differences among subgroups that should be considered in intervention development.

The study of dentition plays an important role in the reconstruction of the diet and in assessment of the overall health and living conditions of paleopopulations. The aim of this study was to determine the condition of permanent dentition of medieval inhabitants of Wrocław basing on the prevalence and intensity of caries in permanent dentition. The material consisted of 1156 permanent teeth from 118 skulls recovered from two medieval cemeteries in Wrocław: the parish cemetery at the St. Elisabeth Church (13th-14th century) and the cemetery in Ołbin (12th-13th century). Two age classes were formed taking into account anthropologic assessment and group size. The younger class consisted of material up to the age of 35 years; the remaining skulls were assigned to the older class. The prevalence and incidence of caries was determined. The prevalence and intensity of caries was 56.91% and 15.7%, respectively. Carious lesions predominated in males and in the older age class. The prevalence and intensity of caries in permanent dentition did not differ from other medieval populations and increased with age. High prevalence of caries reflects a high proportion of carbohydrates in the diet of medieval inhabitants of Wrocław, their high socioeconomic status, and poor oral hygiene.

The purpose of this study was to document the current status of small mammal populations inhibiting the 200 Area plateau near the B-C Crib management area and to compare them with populations inhabiting a protected (control) area within the confines of the Hanford ALE Reserve. Sampling sessions were conducted over two field seasons (1974 and 1975). A total of five species was detected within intensive study areas. These included the Great Basin pocket mouse (Perognathus parvus), deer mouse (Peromyscus maniculatus), northern grasshopper mouse (Onychomys leucogaster), sagebrush vole (Lagurus curtatus), and western harvest mouse (Reithrodontomys megalotis). These species are probably representative of those found throughout the area at this particular elevation. Townsends ground squirrel (Spermophilus townsendii) also occurs in this area but did not occur on the sampling plots during the study duration. The pocket mouse was the only species present in sufficient numbers to permit a detailed analysis of population parameters. A discussion concerning the role small mammals play in mineral cycling and energy transfer processes is included along with a diagram depicting food web interrelationships for consumers inhabiting the 200 Area plateau region. Estimates of small mammal density and biomass provided in this document are needed for an overall understanding of the role biota play in the transfer of waste nuclides

Analysis of diversity of wood-inhabiting fungi retrieved from a Mediterranean forest dominated by Pinus pinaster Aiton

Full Text Available The present paper is focused on the diversity of wood-inhabiting fungi in a poorly investigated habitat: a Mediterranean forest dominated by maritime pine. The sampling area lies in Tocchi biogenetic Reserve, located in the province of Siena (Tuscany, Italy. The monitoring campaign was carried out in 10 permanents plots, taking note of all the fungal species found on each piece of dead wood, irrespective of size and stage of decay. Over one year of surveys, 56 taxa of wood-inhabiting fungi were recorded, among which 39 are corticoids species, 16 polypores and 1 Heterobasidiomycetes. The fungal community seems to be dominated by a small number of species, which are more abundant than the others. Moreover, there are some specific features of deadwood influencing the species composition, such as the presence of coarse woody debris at the first decay stage and fine woody debris at the late decay stages. The results allowed characterizing the wood-inhabiting fungal community in this forest reserve, broadening our knowledge on several species and providing a preliminary database for further studies in Mediterranean areas.

State space model extraction of thermohydraulic systems – Part I: A linear graph approach

International Nuclear Information System (INIS)

Uren, K.R.; Schoor, G. van

2013-01-01

Thermohydraulic simulation codes are increasingly making use of graphical design interfaces. The user can quickly and easily design a thermohydraulic system by placing symbols on the screen resembling system components. These components can then be connected to form a system representation. Such system models may then be used to obtain detailed simulations of the physical system. Usually this kind of simulation models are too complex and not ideal for control system design. Therefore, a need exists for automated techniques to extract lumped parameter models useful for control system design. The goal of this first paper, in a two part series, is to propose a method that utilises a graphical representation of a thermohydraulic system, and a lumped parameter modelling approach, to extract state space models. In this methodology each physical domain of the thermohydraulic system is represented by a linear graph. These linear graphs capture the interaction between all components within and across energy domains – hydraulic, thermal and mechanical. These linear graphs are analysed using a graph-theoretic approach to derive reduced order state space models. These models capture the dominant dynamics of the thermohydraulic system and are ideal for control system design purposes. The proposed state space model extraction method is demonstrated by considering a U-tube system. A non-linear state space model is extracted representing both the hydraulic and thermal domain dynamics of the system. The simulated state space model is compared with a Flownex ® model of the U-tube. Flownex ® is a validated systems thermal-fluid simulation software package. - Highlights: • A state space model extraction methodology based on graph-theoretic concepts. • An energy-based approach to consider multi-domain systems in a common framework. • Allow extraction of transparent (white-box) state space models automatically. • Reduced order models containing only independent state

Numbers and types of microorganisms in uranium mill tailings were determined using culturing techniques. Arthrobacter were found to be the predominant microorganism inhabiting the sandy tailings, whereas Bacillus and fungi predominated in the slime tailings. Sulfate-reducing bacteria, capable of leaching radium, were isolated in low numbers from tailings samples but were isolated in significantly high numbers from topsoil in contact with the tailings. The results are placed in the context of the magnitude of uranium mill tailings in the United States, the hazards posed by the tailings, and how such hazards could be enhanced or diminished by microbial activities. Patterns in the composition of the microbial population are evaluated with respect to the ecological variables that influence microbial growth. ?? 1987 Springer-Verlag New York Inc.

The main factors contributing to variation in metal concentrations in earthworms inhabiting floodplain soils were investigated in three floodplains differing in inundation frequency and vegetation type. Metal concentrations in epigeic earthworms showed larger seasonal variations than endogeic earthworms. Variation in internal levels between sampling intervals were largest in earthworms from floodplain sites frequently inundated. High and low frequency flooding did not result in consistent changes in internal metal concentrations. Vegetation types of the floodplains did not affect metal levels in Lumbricus rubellus, except for internal Cd levels, which were positively related to the presence of organic litter. Internal levels of most essential metals were higher in spring. In general, no clear patterns in metal uptake were found and repetition of the sampling campaign will probably yield different results. - Metal levels in earthworms show large variation among sites, among seasons and among epigeic and endogeic species

From May to July 1972, the disease states of 2096 inhabitants (710 men and 1386 women) in the Fukushima Ward of Osaka City, where the concentration of sulfur trioxide in the air was (yearly average) 1.81 mg/day/100 sq cm and that of carbon monoxide was 5.3 ppM, and that of nitrogen dioxide was 5.3 ppM, were surveyed. The number of persons surveyed was 2.9% of all the inhabitants of the Ward. Twenty-two point one percent were in their thirties, 20.1% in their forties, 16.5% in their sixties, and 15.3% in their fifties. Those who experienced chest diseases were 2.9% of the total, and those with heart diseases were 1.5%. Non-smoking men were 31.7% of the total. The percentage of long-term complaints of cough and sputum was 11.8% in the eastern section, 11.2% in the northern section, 10.0% in the southern section, 6.8% in the western section of the Ward. The frequency of complaints was highest in the sixties (12.7%), followed by 11.5% in the fifties, 11.3% in the thirties, and 8.6% in the forties. The frequency of complaints from men was 11.1% and that from women was 6%. The frequency of complaints was 19.8% in smokers, 8.5% in those who smoked less, and 6.8% in non-smokers. The frequency of complaints classified by residential area showed 12.6% in industrial areas, and 7.8% in residential and commercial areas. The frequency of complaints of inhabitants who live along National Road No. 2 was relatively high, ranging from 15.0 to 18.8%, and the frequency of complaints of inhabitants was apparently higher than those of people who only work in the Ward.

Full Text Available A colour space is seen as an actual discourse when discussing problems of formation and inhabitation of the modern city environment. The key aspect of such understanding is an activity-cultural interpretation of the urban environment colouristics proposed by the author, which allows building of an integral sphere of colour existence. This model of working with colour includes basic components and structures a colour space, while matching up all the elements (basic paradigms that provide proper functioning and development of the colour space; mechanisms of formation of colour paradigms; processes of formation and transformation of cultural norms and stereotypes; the culture of colour as a holistic unit that penetrates the variety of colour space forms, as well as the reality of colour establishment in the framework of human culture; the urban colouristics as a material and virtual, artificial and natural, organized and spontaneously appearing colour reality together with professional and conventional visions of it, etc..

Full Text Available The aim of this article is to evaluate the effect of neighborhood public space transformation due to rapid urbanization in Tehran since 1960s, on the formation of neighborhood identity. In order to find the role of public spaces in enhancing neighborhood identities, two middle class neighborhoods with different spatial organizations are compared with each other: Nazi Abad a planned neighborhood and Mehran a typical unplanned neighborhood which developed through rapid urbanization.   Next, the effect of neighborhood public spaces on neighborhood inhabitants is evaluated from two perspectives: Perceptual dimension and social dimension. The findings indicate that planned spatial organization and various neighborhood public spaces result in stronger neighborhood identity. It enhances both perceptual dimension of neighborhood identity(place attachment and its social dimension (sense of community. In contrast unplanned spatial organization which is the typical feature of Tehran neighborhoods leads to weak neighborhood identity.

Erlandsson, B.

1999-01-01

The body burden of 137 Cs in the population of two Swedish cities, Lund and Gaevle has been calculated from measurements of the activity concentration in the sewage sludge from sewage treatment plants serving these cities. Now 13 years after the Chernobyl accident the activity in the run-off water during the winter season, January to March, and during dry periods is very low. Already 1996, 10 years after the accident, the distribution of the mean value of the activity concentration of 137 Cs has leveled out, and does not depend on the amount of precipitation. Therefor almost all 137 Cas activity can be determined as coming from the inhabitants of the two cities. The number of inhabitants and the distribution of men, women and children are well known for both Lund and Gaevle. These values are in good agreement with values obtained from whole-body measurements. (au)

Ramzan, N.; Noreen, N.; Shahzad, S.

2014-01-01

During the present studies, compost-inhabiting microorganisms including 44 fungi and 15 bacteria isolated from different compost samples were evaluated for their in vitro efficacy against soil-borne pathogens viz., Fusarium solani, Macrophomina phaseolina, Pythium aphanidermatum, Rhizoctonia solani, and Sclerotium rolfsii. Compost inhabiting microbes like Trichoderma harzianum, T. virens, Bacillus cereus, B. pumilus, B. subtilis, Micrococcus varians and Pseudomonas fluorescens were found to inhibit all the test pathogens. Acrophialophora fusispora and Penicillium citrinum reduced the mycelial growth of all the test pathogens except Sclerotium rolfsii. Bacillus licheniformis and Bacillus megaterium showed biocontrol activity against all the pathogens except Rhizoctonia solani. Trichoderma harzianum parasitized mycelia of all the tested pathogens and produced coiling around the mycelium. (author)

Identifying ongoing tuberculosis infection sites is crucial for breaking chains of transmission in tuberculosis-prevalent urban areas. Previous studies have pointed out that detection of local accumulation of tuberculosis patients based on their residential addresses may be limited by a lack of matching between residences and tuberculosis infection sites. This study aimed to identify possible tuberculosis hotspots using TB genotype clustering statuses and a concept of "activity space", a place where patients spend most of their waking hours. We further compared the spatial distribution by different residential statuses and describe urban environmental features of the detected hotspots. Culture-positive tuberculosis patients notified to Shinjuku city from 2003 to 2011 were enrolled in this case-based cross-sectional study, and their demographic and clinical information, TB genotype clustering statuses, and activity space were collected. Spatial statistics (Global Moran's I and Getis-Ord Gi* statistics) identified significant hotspots in 152 census tracts, and urban environmental features and tuberculosis patients' characteristics in these hotspots were assessed. Of the enrolled 643 culture-positive tuberculosis patients, 416 (64.2%) were general inhabitants, 42 (6.5%) were foreign-born people, and 184 were homeless people (28.6%). The percentage of overall genotype clustering was 43.7%. Genotype-clustered general inhabitants and homeless people formed significant hotspots around a major railway station, whereas the non-clustered general inhabitants formed no hotspots. This suggested the detected hotspots of activity spaces may reflect ongoing tuberculosis transmission sites and were characterized by smaller residential floor size and a higher proportion of non-working households. Activity space-based spatial analysis suggested possible TB transmission sites around the major railway station and it can assist in further comprehension of TB transmission dynamics in an

The determination of external dose to teeth of inhabitants of settlements near the Semipalatinsk Nuclear Test Site (SNTS) was conducted using the EPR dosimetry technique to assess radiation doses associated with exposure to radioactive fallout from the test site. In this study, tooth doses have been reconstructed for 103 persons with all studied teeth having been formed before the first nuclear test in 1949. Doses above those received from natural background radiation, termed "accident doses", were found to lie in the range from zero to approximately 2 Gy, with one exception, a dose for one person from Semipalatinsk city was approximately 9 Gy. The variability of reconstructed doses within each of the settlements demonstrated heterogeneity of the deposited fallout as well as variations in lifestyle. The village mean external gamma doses for residents of nine[ settlements were in the range from a few tens of mGy to approximately 100 mGy.

Urban community contributes to the development of any city, but it is essential that its residents can live, work and relax in a friendly environment. The source of their well-being and positive aesthetic experience is a harmonious landscape, shaped by the functional spatial layout of streets, blocks of buildings and structures and the accompanying elements of nature and development, ensuring the rational development of urban space. The need to knowing of public expectations in relation to residence, is an important step in planning new investments by developers and construction companies. In order to carry out of research cooperation has been established with the construction company. Cooperation allowed to gain experience in the commercialization and implementation of research and carry out analysis and evaluation of spatial structures in terms of urban development and functional housing estates, with special emphasis on the needs of society. The observations focused in particular on ecological building and the necessity of the creation and development of green areas, sports and recreation to residential areas. We know that every square meter of land designated for housing carries a possible profit for the developer. The more will be built and sold apartments the more earn the investor. However, to the apartment were popular meet the demands of customers concerning not only the housing unit, but also the environment in which the building is situated. It is therefore important that the settlements were attractive and meet the social needs of society. Social needs are related to satisfying the expectations of the inhabitants of the settlements related to the comfort of the apartment, being, rest and recreation living within the zone of residence. As part of the research work carried study work and field research. They consisted gain knowledge about work organization in the enterprise and hearing the reasons and scope of the activities the developer, as well as get

Adiaspiromycosis is a rare fungal infection caused by saprophytic fungi Emmonsia spp. (type Ascomycota) occurring especially in small free-living mammals. The aim of this study was to evaluate the occurrence of histopathological lesions asscociated with adiaspiromycosis in the Eurasian beaver inhabiting Poland. In order to evaluate the presence of natural adiaspiromycosis we systematically investigated beaver populations from north-eastern Poland for adiaspores in the lungs. This study reveals for the first time the presence of pulmonary adiaspiromycosis of Eurasian beaver in Poland. As far as we know, there is no published data regarding pulmonary adiaspiromycosis in human patients in Poland.

Boreman, J.; Goodyear, C.P.

1988-01-01

An empirically derived age-, time-, and space-variant equation was used to estimate entrainment mortality at power plants for seven fish species inhabiting the Hudson River estuary. Entrainment mortality is expressed as a conditional rate, which is the fractional reduction in year-class strength due to entrainment if other sources of mortality are density-independent. Estimates of the conditional entrainment mortality, based on historical and projected once-through cooling operation of five power plants, were 11-22% for striped bass, 11-17% for white perch, 5-7% for Atlantic tomcod, 14-21% for American shad, 4-11% for river herring (alewife and blueback herring combined), and 35-79% for bay anchovy. Closed-cycle cooling (natural-draft cooling towers) at three of the power plants (Indian Point, Bowline Point, and Roseton) would reduce entrainment mortality of striped bass by 50-80%, of white perch by 75-80%, of Atlantic tocod by 65-70%, of American shad by 80%, of river herring by 30-90%, and of bay anchovy by 45-80%. The life stages most vulnerable to entrainment mortality were post-yolk-sac larva and entrainable size juvenile. 18 refs., 7 tabs

The design presented in this paper is in response to the revolution in private space activities, the increasing public interest in commercial flights to space and the utilization of structures such as space hotels or private orbital habitats. The baseline for the Omicron design concept is the Russian Salyut derived space station module. Salyut was the first space station to orbit the Earth. Its unique design and technical features were what made the development of space stations Salyut 1-7, MIR and the International Space Station (ISS) Zwezda service module possible. Due to its versatility and the reliable operating launch vehicle Proton, this space module series has the potential to be adapted for space hotel development. This paper proposes a conceptual design of the space habitat called Omicron, with particular focus on interior design for the microgravity environment. The Omicron concepts address the needs of space tourism with a strong emphasis on the safety and comfort of the spaceflight participants. The Omicron habitat supports three inhabitants in nominal conditions (e.g., two passengers and one astronaut). The habitat provides a flexible interior, facilities and spaces dynamically transforming in order to accommodate various types of activities, which will be performed in an organically formed interior supporting spatial orientation and movement in microgravity. The future development potential of Omicron is also considered. The baseline version is composed solely of one rigid module with an inverted cupola for observations. An alternative version offers more space using an inflatable structure. Finally, a combination of multiple Omicron modules enables the creation of a larger orbital habitat. The Omicron's subsystems support a few days visit by trained passengers. The transport to the habitat would be provided e.g., by the Soyuz TMA spacecraft carried by the Soyuz launch vehicle in the early stage of Omicron's development, before a fully reusable

Full Text Available Background Cockatiels (Nymphicus hollandicus were originally endemic to Australia; now they are popular pets with a global distribution. It is now possible to conduct detailed molecular studies on cultivable and uncultivable bacteria that are part of the intestinal microbiome of healthy animals. These studies show that bacteria are an essential part of the metabolic capacity of animals. There are few studies on bird microbiomes and, to the best of our knowledge, this is the first report on the cockatiel microbiome. Methods In this paper, we analyzed the gut microbiome from fecal samples of three healthy adult cockatiels by massive sequencing of the 16S rRNA gene. Additionally, we compared the cockatiel fecal microbiomes with those of other bird species, including poultry and wild birds. Results The vast majority of the bacteria found in cockatiels were Firmicutes, while Proteobacteria and Bacteroidetes were poorly represented. A total of 19,280 different OTUs were detected, of which 8,072 belonged to the Erysipelotrichaceae family. Discussion It is relevant to study cockatiel the microbiomes of cockatiels owing to their wide geographic distribution and close human contact. This study serves as a reference for cockatiel bacterial diversity. Despite the large OTU numbers, the diversity is not even and is dominated by Firmicutes of the Erysipelotrichaceae family. Cockatiels and other wild birds are almost depleted of Bacteroidetes, which happen to be abundant in poultry-related birds, and this is probably associated with the intensive human manipulation of poultry bird diets. Some probable pathogenic bacteria, such as Clostridium and Serratia, appeared to be frequent inhabitants of the fecal microbiome of cockatiels, whereas other potential pathogens were not detected.

To summarize the data on the prevalence of type 1 diabetes mellitus among 15-34-year-aged Lithuania inhabitants (1991-2010). New prevalent cases consist of growing-up patients with diabetes onset in childhood, i.e., up to 14 years, new onset 15-34-year-aged type 1 diabetic patients Lithuanian inhabitants, and immigrants. The data on type 1 diabetes was collected with the help of general practitioners and regional endocrinologists in Lithuania. On 31 December 1991, there were 1202 adolescent and adult 15-34-year-aged patients with type 1 diabetes mellitus or 103.59 per 100,000 inhabitants of the same age group (95% Poisson CI 97.90-109.62), and at the end of 2010 - 1533 or 187.80 (178.63-197.44), respectively in Lithuania. During 19-year period the mean increase of type 1 diabetic patients was 1.25±1.94% per year or 1.47±2.74 per 100,000 inhabitants per mean year of the study period (for males 1.42±2.14% or 1.69±3.05/100,000 and for females 1.05±1.99%, or 1.24±2.92/100,000). Regression-based linear trends showed that the prevalence of type 1 diabetes mellitus in 15-34-year-age group had a tendency to increase among males (r=0.953; p1) and females (r=0.970; p1). The age adjusted prevalence frequencies for males and females in 1991 were correspondingly 102.81/100,000 and 104.55/100,000, and in 2010 - 193.75 and 182.01.

The increasing human impact on the earth's biosphere is inflicting changes at all spatial scales. As well as deterioration and fragmentation of natural biological systems, these changes also led to other, unprecedented effects and emergence of novel habitats. In boreal zone, intensive forest management has negatively impacted a multitude of deadwood-associated species. This is especially alarming given the important role wood-inhabiting fungi have in the natural decay processes. In the boreal zone, natural broad-leaved-dominated, herb-rich forests are threatened habitats which have high wood-inhabiting fungal species richness. Fungal diversity in other broadleaved forest habitat types is poorly known. Traditional wood pastures and man-made afforested fields are novel habitats that could potentially be important for wood-inhabiting fungi. This study compares species richness and fungal community composition across the aforementioned habitat types, based on data collected for wood-inhabiting fungi occupying all deadwood diameter fractions. Corticioid and polyporoid fungi were surveyed from 67 130 deadwood particles in four natural herb-rich forests, four birch-dominated wood pastures, and four birch-dominated afforested field sites in central Finland. As predicted, natural herb-rich forests were the most species-rich habitat. However, afforested fields also had considerably higher overall species richness than wood pastures. Many rare or rarely collected species were detected in each forest type. Finally, fungal community composition showed some divergence not only among the different habitat types, but also among deadwood diameter fractions. Synthesis and applications : In order to maintain biodiversity at both local and regional scales, conserving threatened natural habitat types and managing traditional landscapes is essential. Man-made secondary woody habitats could provide the necessary resources and serve as surrogate habitats for many broadleaved deadwood

The Space Physics of Life: Searching for Biosignatures on Habitable Icy Worlds Affected by Space Weathering

Science.gov (United States)

Cooper, John F.

2006-01-01

Accessible surfaces of the most likely astrobiological habitats (Mars, Europa, Titan) in the solar system beyond Earth are exposed to various chemical and hydrologic weathering processes directly or indirectly induced by interaction with the overlying space environment. These processes can be both beneficial, through provision of chemical compounds and energy, and destructive, through chemical dissociation or burial, to detectable presence of biosignatures. Orbital, suborbital, and surface platforms carrying astrobiological instrumentation must survive, and preferably exploit, space environment interactions to reach these habitats and search for evidence of life or its precursors. Experience from Mars suggests that any detection of biosignatures must be accompanied by characterization of the local chemical environment and energy sources including irradiation by solar ultraviolet photons and energetic particles from the space environment. Orbital and suborbital surveys of surface chemistry and astrobiological potential in the context of the space environment should precede targeted in-situ measurements to maximize probability of biosignature detection through site selection. The Space Physics of Life (SPOL) investigation has recently been proposed to the NASA Astrobiology Institute and is briefly described in this presentation. SPOL is the astrobiologically relevant study of the interactions and relationships of potentially? or previously inhabited, bodies of the solar system with the surrounding environments. This requires an interdisciplinary effort in space physics, planetary science, and radiation biology. The proposed investigation addresses the search for habitable environments, chemical resources to support life, and techniques for detection of organic and inorganic signs of life in the context of the space environment.

Oral diseases, including dental caries and periodontitis, are among the most prevalent diseases worldwide and develop as a consequence of a microbial dysbiosis. Several bacterial strains are being tested as potential oral health-promoting organisms, but usually they are species isolated from niches other than the site where they must exert its probiotic action, typically from fecal samples. We hypothesize that oral inhabitants associated to health conditions will be more effective than tradit...

Tardigrades in Space Research - Past and Future

To survive exposure to space conditions, organisms should have certain characteristics including a high tolerance for freezing, radiation and desiccation. The organisms with the best chance for survival under such conditions are extremophiles, like some species of Bacteria and Archea, Rotifera, several species of Nematoda, some of the arthropods and Tardigrada (water bears). There is no denying that tardigrades are one of the toughest animals on our planet and are the most unique in the extremophiles group. Tardigrada are very small animals (50 to 2,100 μm in length), and they inhabit great number of Earth environments. Ever since it was proven that tardigrades have high resistance to the different kinds of stress factors associated with cosmic journeys, combined with their relatively complex structure and their relative ease of observation, they have become a perfect model organism for space research. This taxon is now the focus of astrobiologists from around the world. Therefore, this paper presents a short review of the space research performed on tardigrades as well as some considerations for further studies.

State space model extraction of thermohydraulic systems – Part II: A linear graph approach applied to a Brayton cycle-based power conversion unit

International Nuclear Information System (INIS)

Uren, Kenneth Richard; Schoor, George van

2013-01-01

This second paper in a two part series presents the application of a developed state space model extraction methodology applied to a Brayton cycle-based PCU (power conversion unit) of a PBMR (pebble bed modular reactor). The goal is to investigate if the state space extraction methodology can cope with larger and more complex thermohydraulic systems. In Part I the state space model extraction methodology for the purpose of control was described in detail and a state space representation was extracted for a U-tube system to illustrate the concept. In this paper a 25th order nonlinear state space representation in terms of the different energy domains is extracted. This state space representation is solved and the responses of a number of important states are compared with results obtained from a PBMR PCU Flownex ® model. Flownex ® is a validated thermo fluid simulation software package. The results show that the state space model closely resembles the dynamics of the PBMR PCU. This kind of model may be used for nonlinear MIMO (multi-input, multi-output) type of control strategies. However, there is still a need for linear state space models since many control system design and analysis techniques require a linear state space model. This issue is also addressed in this paper by showing how a linear state space model can be derived from the extracted nonlinear state space model. The linearised state space model is also validated by comparing the state space model to an existing linear Simulink ® model of the PBMR PCU system. - Highlights: • State space model extraction of a pebble bed modular reactor PCU (power conversion unit). • A 25th order nonlinear time varying state space model is obtained. • Linearisation of a nonlinear state space model for use in power output control. • Non-minimum phase characteristic that is challenging in terms of control. • Models derived are useful for MIMO control strategies

The paper deals with the study of the spatial distribution and the design of sampling plans for estimating nymph densities of the grape leafhopper Scaphoideus titanus Ball in vine plant canopies. In a reference vineyard sampled for model parameterization, leaf samples were repeatedly taken according to a multistage, stratified, random sampling procedure, and data were subjected to an ANOVA. There were no significant differences in density neither among the strata within the vineyard nor between the two strata with basal and apical leaves. The significant differences between densities on trunk and productive shoots led to the adoption of two-stage (leaves and plants) and three-stage (leaves, shoots, and plants) sampling plans for trunk shoots- and productive shoots-inhabiting individuals, respectively. The mean crowding to mean relationship used to analyze the nymphs spatial distribution revealed aggregated distributions. In both the enumerative and the sequential enumerative sampling plans, the number of leaves of trunk shoots, and of leaves and shoots of productive shoots, was kept constant while the number of plants varied. In additional vineyards data were collected and used to test the applicability of the distribution model and the sampling plans. The tests confirmed the applicability 1) of the mean crowding to mean regression model on the plant and leaf stages for representing trunk shoot-inhabiting distributions, and on the plant, shoot, and leaf stages for productive shoot-inhabiting nymphs, 2) of the enumerative sampling plan, and 3) of the sequential enumerative sampling plan. In general, sequential enumerative sampling was more cost efficient than enumerative sampling.

2006-01-01

In the period of 2001-2004, frequency of cells bearing mutations at T-cell receptor (TCR) locus was assessed in 553 inhabitants of radiation polluted regions of the Russian Federation and 154 unexposed control persons. The inhabitants were divided into three groups according to age at the moment of the Chernobyl disaster and 137Cs pollution density: 1) in utero, 37-555 kBq/m2; 2) 0-14 years old, 20-555 kBq/m2; 3) 18 and more years old, highest 137Cs density (185 more than 555 kBq/m2). The most intense changes of the TCR-mutant cell frequency were observed in the group of persons exposed to ionizing radiation in utero. The mean frequency of the mutant cells was higher in the first group than in age-matched control group by about 1.5-fold: 4.0 x 10(-4) vs 2.7 x 10(-4) accordingly (p Chernobyl accident). The changes of the TCR-mutant cell frequency in persons exposed in pre- and postnatal periods differ not only quantitatively, but qualitatively. In the fist case all persons react to irradiation by increasing number of the TCR-mutant cells in some degree. In the second case - only a part of population. Proportion of reacting persons depends on age at the start of irradiation and, perhaps, on dose absorbed. The TCR-mutant frequency was significantly higher in persons with benign tumors of different localizations and nodules in thyroid gland than in persons without this pathology.

Schwanzer, Michael; Fensel, Anna

We investigate services giving users an adequate insight on his or her energy consumption habits in order to optimize it in the long run. The explored energy awareness services are addressed to inhabitants of smart homes, equipped with smart meters, advanced communication facilities, sensors and actuators. To analyze the potential of such services, a game at a social network Facebook has been designed and implemented, and the information about players' responses and interactions within the game environment has been collected and analyzed. The players have had their virtual home energy usage visualized in different ways, and had to optimize the energy consumption basing on their own perceptions of the consumption information. Evaluations reveal, in particular, that users are specifically responsive to information shown as a real-time graph and as costs in Euro, and are able to produce and share with each other policies for managing their smart home environments.

Field studies were conducted to investigate arsenic (As), copper (Cu), and zinc (Zn) contamination in agricultural soils and wheat crops at two areas in Huaibei, China. Area A is in the proximity of Shuoli coal mine. In area B, three coal mines and a coal cleaning plant were distributed. The potential health risk of As, Cu, and Zn exposure to the local inhabitants through consumption of wheat grains was also estimated. The results showed that significantly higher (psoils collected from area B than in those from area A. Arsenic concentrations in wheat sampled from area A were negatively correlated with the distance from the coal mine (p<0.001). Concentrations of Cu and Zn in wheat seedlings and grains collected from area B were significantly higher (p<0.05) than in those collected from area A, with the exception of Zn in wheat seedlings. Concentrations of Cu and Zn in most wheat grain samples were above the permissible limits of Cu and Zn in edible plants set by the Food and Agriculture Organization/World Health Organization. The hazard index of aggregate risk through consumption of wheat grains was 2.3-2.4 for rural inhabitants and 1.4-1.5 for urban inhabitants. The average intake of inorganic As for rural inhabitants in Huaibei was above 10 μg day(-1). These findings indicated that the inhabitants around the coal mine are experiencing a significant potential health risk due to the consumption of locally grown wheat.

For the last 25 years, every two to three years the Conferencia Latinoamericana de Geofísica Espacial (COLAGE) is held in one of the Latin American countries for the purpose of promoting scientific exchange among scientists of the region and to encourage continued research that is unique to this area of the world. At the more recent conference, the community realized that many individuals both within and outside Latin America have contributed greatly to the understanding of the space sciences in this area of the world. It was therefore decided to assemble a Special Issue Space and Geophysical Physics related to Latin America, presenting recent results and where submissions would be accepted from the world wide community of scientists involved in research appropriate to Latin America. Because of the large number of submissions, these papers have been printed in two separate issues. The first issue was published in Advances in Space Research, Vol. 57, number 6 and contained 15 papers. This is the second issue and contains 25 additional papers. These papers show the wide variety of research, both theoretical and applied, that is currently being developed or related to space and geophysical sciences in the Sub-Continent.

Evaluation of daily intake for some elements of radiation protection concern by inhabitants of Greater Cairo Area, Egypt

Mohamed H.E. Monged

2016-07-01

Full Text Available Concentrations of K, Ca, U, Th, Cs, Sr, I, Al, Cd, Cu, Mn, Pb, Ni, Zn and Cr were determined in common foodstuffs consumed by adult inhabitants of Greater Cairo Area (GCA. Some of these elements have chemical and biological similarity to some of the radionuclides abundantly encountered during nuclear power production and therefore data on these elements could provide important information on their biokinetic behavior. A total of 120 samples were analyzed using Neutron Activation Analysis (NAA and Atomic Absorption Spectrometry (AAS. Highest contributions for the intake of micronutrients (Cu, Mn, Ni and Zn arise from broad bean, rice and wheat flour consumption. Meat, milk, eggs and some vegetables are the major sources of K, Ca, U, Th, Cs, Al, Cd and Pb intake. The medium daily intakes for the adult inhabitants of GCA from the analyzed elements were reported. The lower daily intake of Ca, Th, Cs and I by adult inhabitants of GCA could be due to significantly lower consumption of milk and milk products. The significantly lower intake of calcium by adult inhabitants of GCA may lead to higher uptake of radiostrontium and could result in perhaps higher internal radiation dose. The lower intake values obtained for thorium and uranium, which suggests that radiation dose from their ingestion at natural background levels, is likely to be lower than what may be concluded from International Commission on Radiological Protection (ICRP data. Concerning micronutrients, the recommended values of daily intake of Cu and Mn are conveniently supplied by diet; however, for Cr and Zn they are lower than the recommended daily allowance. Due to high metals concentrations and consumption rates, broad bean is the foodstuff that provided the highest ingestion rates of Cu, Mn, Ni and Zn, being therefore a very important source of micronutrients.

Highlights: ► Human population environmentally exposed to uranium mining wastes. ► Significantly higher levels of manganese and uranium in peripheral blood samples. ► Significant DNA damages detected by the comet assay. ► Significant decrease of NK and T lymphocytes counts in exposed individuals. ► Concerns on the risks of human populations living nearby uranium mining areas. - Abstract: Environmental exposure to uranium and its daughter radionuclides, has been linked to several negative effects such as those related with important physiological processes, like hematopoiesis, and may also be associated with genotoxicity effects. Herein, genotoxic effects, immunotoxicity, trace elements and C reactive protein (CRP) analyses, were performed in peripheral blood samples collected from individuals of a population living near a deactivated uranium mine. C reactive protein analysis was performed to exclude candidates with active inflammatory processes from further evaluations. DNA damage and immunotoxicity (immunophenotyping and immune cell counts) were evaluated by comet assay and flow cytometry, respectively. Significant DNA damage was observed in the peripheral blood samples from volunteers living in the Cunha Baixa village. A significant decrease of NK and T lymphocytes counts were observed in the individuals from the Cunha Baixa village, when compared with individuals from the reference site. Uranium and manganese levels were significantly higher in the Cunha Baixa village inhabitants. On the other hand, zinc levels were significantly lower in those individuals when compared with the volunteers from the control village. Results suggest that inhabitants from Cunha Baixa have a higher risk of suffering from serious diseases such as cancer, since high DNA damages were observed in peripheral blood leukocytes and also decreased levels of NK and T cells, which play an essential role in the defense against tumor growth

The common trend of urban population has been growing significantly in Indonesia for decades, are affected by urban green space conversion. Generally, this area is utilized for urban infrastructures and residences. Furthermore, urban area has grown uncontrollably that could enhance the phenomenon of urban sprawl. The conversion of green urban area and agricultural area will significantly decrease urban food security and quality of urban environment. This problem becomes a serious issue for urban sustainability. Bandung is a city with dense population where there are many poor inhabitants. Families living in poverty are subjected to food insecurity caused by the rise of food prices. Based on the urgency of urban food security and urban environment quality the local government has to achieve comprehensive solutions. This research aims to formulate the policy of productive green open space towards food security for poor people in Bandung. This research not only examines the role played by productive green open space to supply food for the urban poor but also how to govern urban areas sustainably and ensure food security. This research uses descriptive explanatory methodology that describes and explains how to generate policy and strategic planning for edible landscape to promote urban food security. Taman Sari is the location of this research, this area is a populous area that has amount of poor people and has a quite worse quality of urban environment. This study shows that urban green open space has the potential to be utilized as an urban farming land, which poor inhabitants could be main actors to manage urban agriculture to provide their food. Meanwhile, local government could contribute to subsidize the financial of urban farming activities.

Each day cities inhabitants are exposed to visual pollution. This work assess the environmental impact caused by visual pollution in public spaces, using as a case of study a mixed-use neighborhood in San Cristobal, the capital of Tachira state, Venezuela. Such assessment was made using a qualitative approach, where special emphasis was paid to the perception of these impacts by a purposive sample of users of this area. The compilation and analysis of information reveal the main visual pollutants existing in these public spaces where, in addition to outdoor advertising, overhead wires, rubbish, graffiti, vacant land, among others, cars and outdoor kiosks. Neighborhood users are sensitive to the presence of visual pollutants, which affects them physically and psychologically, as well as for the visual quality of their environment. Such signs were used to guide a qualitative appraisal of environmental impacts generated by these circumstances and to propose policies to mitigate them.

In the period of 2001-2004, the mutation frequency at T-cell receptor (TCR) locus was assessed in 553 inhabitants of contamination regions of the Russian Federation and 154 unexposed control persons. The inhabitants were divided into three groups according to age at the moment of the Chernobyl disaster and 137 Cs contamination density. The most intense changes of the TCR-mutant cell frequency was observed in the group of persons exposed to prenatal irradiation. The excess in the mean TCR-mutant cell frequency was less expressed in the group of inhabitants aged 0-14 years at the moment of irradiation start. It was not found significant differences in mutation frequency between the control group and adults consisting in the third group (18 and more years old). The changes of the TCR-mutant cell frequency in persons exposed in prenatal and postnatal periods differ not only quantitatively, but qualitatively. The TCR-mutant frequency was significantly higher in persons with benign tumors of different localizations and nodules in thyroid gland than in persons without this pathology [ru

The European model for inhabited areas (ERMIN), developed for prediction of radioactive compounds Chernobyl accident, was applied at Tomioka in Fukushima Prefecture as a model region for decontamination to investigate its feasibility. The application of ERMIN to eight compartments with each 100 x 100 m in this region, where decontamination was actually performed, confirmed that observed air dose rates were within the calculated counterparts irrespective of presence or absence of a term on environment half life for two months. With simulation sets capable of reproducing an air dose rate during a decontamination term, decontamination strategies incorporating five evaluation items, i.e. reduction of radiation exposure to inhabitants, cost for decontamination, the amount of waste, work effort, and the amount of radiation exposure for a worker, were proposed and compared. By initiating decontamination 9 months after the accident in Fukushima, radiation exposure to inhabitants, who continue to live at the modeled region, is reduced by about 24 mSv for the ensuring 15 months. Furthermore, decontamination strategies were compared by prioritizing the five evaluation items. (author)

The belives on the asphalt. Sacred sites as means of appropriation of the public space in México City

Directory of Open Access Journals (Sweden)

María Ana Portal

2009-07-01

Full Text Available This paper explores how residents of México City appropriate public spaces by transforming local places into sacred sites.  This sacred quality is achieved by installing crucifixes, altars and niches for virgins and saints.  These symbols of folk religion not only adorn public sites, but also offer protection, serve as mnemonic devices and manage spatial liminality -all this in a chaotic city where public spaces are considered to be almost extinct.  These elements -- faces, proper names, common religious symbols- mark “anonymous” urban spaces, generating meaning and memory for inhabitants.  In this fashion, public spaces become a scenario for projecting personal elements of  neighborhood groups.

Sandra Valeria Ursino

2012-01-01

Full Text Available In this article, we present some of the results and argumentative lines used in the analysis of the field work carried out in the neighborhoods of Porst, Danubio and Villa Inflamable, in the Dock Sud area, located in the district of Avellaneda, province de Buenos Aires, during 2010 and 2011. Within this framework, we observed and recorded the inhabitants' usual routes around the neighborhood, which is environmentally polluted but which has also been symbolically appropriated. Along these lines then, our general aim was to learn about social representations, representation spaces and the spatial practices of the inhabitants of the most affected neighborhoods of Dock Sud due to the area's environmental issues. To this end, there was a reconstruction of the subjects' practices in the neighborhood, of the hegemonic discourse about the pollution in this place and, finally, the population's conflict and struggle practices

Hepatozoon ellisgreineri n. sp. (Hepatozoidae): description of the first avian apicomplexan blood parasite inhabiting granulocytes.

Science.gov (United States)

Valkiūnas, Gediminas; Mobley, Kristin; Iezhova, Tatjana A

2016-02-01

Blood parasites of the genus Hepatozoon (Apicomplexa, Hepatozoidae) infect all groups of terrestrial vertebrates, and particularly high prevalence and species diversity have been reported in reptiles and mammals. A few morphologically similar species, in which gamonts inhabit mononuclear leukocytes and red blood cells, have been described in birds. Here, we report a new Hepatozoon species, which was found in wild-caught secretary birds Sagittarius serpentarius, from Tanzania. Hepatozoon ellisgreineri n. sp. can be readily distinguished from all described species of avian Hepatozoon because its gamonts develop only in granulocytes, predominantly in heterophils, a unique characteristic among bird parasites of this genus. Additionally, this is the first reported avian apicomplexan blood parasite, which inhabits and matures in granulocytes. We describe H. ellisgreineri based on morphological characteristics of blood stages and their host cells. This finding broadens knowledge about host cells of avian Hepatozoon spp. and other avian apicomplexan blood parasites, contributing to the better understanding of the diversity of haematozoa. This is the first report of hepatozoonosis in endangered African birds of the Sagittariidae.

Full Text Available BACKGROUND: Plant invasions are causing habitat degradation in Galapagos. Problems are concentrated on the four inhabited islands. Plants introduced to rural areas in the humid highlands and urban areas on the arid coast act as foci for invasion of the surrounding Galapagos National Park. METHODOLOGY/PRINCIPAL FINDINGS: Here we present results of the most comprehensive inventory to date of alien vascular plants in the inhabited areas of Galapagos. The survey was conducted between 2002 and 2007, in 6031 properties (97% of the total on Floreana, Isabela, San Cristobal and Santa Cruz Islands. In total 754 alien vascular plant taxa were recorded, representing 468 genera in 123 families. Dicotyledons represented 554 taxa, monocotyledons 183, there were 7 gymnosperms and 10 pteridophytes. Almost half (363 of the taxa were herbaceous. The most represented families were Fabaceae (sensu lato, Asteraceae and Poaceae. The three most recorded species in the humid rural areas were Psidium guajava, Passiflora edulis and Bryophyllum pinnatum, and in the dry urban areas, Aloe vera, Portulaca oleracea and Carica papaya. In total, 264 (35% taxa were recorded as naturalized. The most common use for taxa was ornamental (52%. CONCLUSIONS/SIGNIFICANCE: This extensive survey has increased the known alien vascular flora of Galapagos by 257 species, giving a ratio of alien to native taxa of 1.57:1. It provides a crucial baseline for plant invasion management in the archipelago and contributes data for meta analyses of invasion processes worldwide. A repeat of the survey in the future would act as an effective early detection tool to help avoid further invasion of the Galapagos National Park.

Full Text Available An awareness of the role of public space is growing among the inhabitants of cities. This space is an integral part of our daily lives. It consists of places outside the home where we spend free time, i.e. the streets we walk on, the squares and greeneries where we meet, as well as playgrounds, parks and green areas where we rest and do sports. The quality of such space affects many aspects of human life.

The US Environmental Protection Agency conducts risk assessments of insecticide applications to wild birds using a model that is limited to the dietary route of exposure. However, free-flying birds are also exposed to insecticides via the inhalation and dermal routes. We measured azinphos-methyl residues on the skin plus feathers and the feet of brown-headed cowbirds (Molothrus ater) in order to quantify dermal exposure to songbirds that entered and inhabited an apple (Malus x domestica) orchard following an insecticide application. Exposure to azinphos-methyl was measured by sampling birds from an aviary that was built around an apple tree. Birds sampled at 36 h and 7-day post-application were placed in the aviary within 1 h after the application whereas birds exposed for 3 days were released into the aviary 4-day post-application. Residues on vegetation and soil were also measured. Azinphos-methyl residues were detected from the skin plus feathers and the feet from all exposure periods. Our results underscore the importance of incorporating dermal exposure into avian pesticide risk assessments.

Annual medical examinations are conducted by Brookhaven National Laboratory (BNL) for a population of Marshallese who were accidentally exposed to radioactive fallout in 1954, for a comparison population, and for all inhabitants of the atolls of Rongelap and Utirik. Disease surveillance includes analysis of serum samples. Elevated serum uric acid (SUA) levels are common along Pacific populations, and modifying environmental factors have been investigated as a cause for this finding. The authors have studied SUA levels of people living in the Marshall Islands, and have found elevated values similar to those reported for other Micronesian populations. The nearly Gaussian distribution of individual serum uric acid values for men, and for women less than or equal to45 years of age, indicates that the elevation is due to a regularized increase in serum uric acid rather than to a subpopulation that has pathologic hyperuricemia. The higher serum uric acid levels appear, therefore, to be normal for the Marshallese, a conclusion supported by the infrequency of clinical gout in the population tested

Bacová, Andrea; Puškár, Branislav; Vráblová, Edita

2017-10-01

The housing estates in Bratislava saturated the housing needs of a large number of inhabitants who come after World War II to the city. Design of public spaces often did not have priority in the process of designing. The solutions for mentioned exterior spaces had been planned after blocks of flat realization, but many of them are not realized to this day. The article analyzes the example of the unrealized public spaces in existing housing estates Devinska Nova Ves and Petržalka (city districts of Bratislava) and offer practical solutions in relation to residencialization method. Residencialization of missing public places is an effective method of adding identities to settlements. It improves the quality of residential environment and public spaces. The main aim is to create better conditions for social activities in public areas, which are missing on the present. The research will be focused on the examination of the urban, cultural and construction potential of the existing residential enviroment in Bratislava. The main aim of residentialization is not only to enhance the quality of spatial and building structures in the selected residential area and maintain long-term sustainability in the pertinent programme area, but mainly to improve the quality of living for the residents. The outputs of the project are proposals and practical procedures developed with regard to planning documents for local municipal authorities and regional organizations. The solutions will have a positive impact on the enhancement of the quality of public spaces, attractive social activities and of a conceptual link - residentialization.

Behavioural adaptations to moisture as an environmental constraint in a nocturnal burrow-inhabiting Kalahari detritivore Parastizopus armaticeps Peringuey (Coleoptera: Tenebrionidae

Directory of Open Access Journals (Sweden)

O.A.E. Rasa

1994-08-01

Full Text Available The nocturnal desert detritivore Parastiz.opus armaticeps shows differences in surface activity patterns and burrow fidelity depending on surface humidity. After rain approximately half of the beetle population, independent of sex, is highly vagile and disperses over long distances. During drought, beetles are more sedentary and show higher burrow fidelity. They also inhabit burrows that are longer and deeper than non-inhabited ones, such burrows being relatively scarce. Burrow fidelity and the adoption of a more sedentary habit during drought are considered strategies to avoid the risks of not locating a suitable burrow before sunrise and subsequent desiccation in shallow burrows.

Cardiovascular mortality among inhabitants of contaminated areas of Ukraine is dependent on the total cumulative effective doses and age at the time of the Chornobyl accident. It is proved by a significantly higher (p < 0.05) mortality in people exposed to 21.00-50.0 mSv radiation doses compared to those having 5.6-20.99 mSv exposures. Mortality was significantly higher (p < 0.05) in age groups with higher doses as opposed to those with low ones. Maximum mortality was observed among inhabitants aged 40-60, while the lowest death rate - in patients younger than 18 years old. The data obtained also suggest that the radiation factor can be considered here as one accelerating the aging and pathophysiological abnormalities in survivors. Coronary heart disease, cerebrovascular disease, arterial hypertension, diseases of arteries, arterioles and capillaries are the main causes of death from cardiovascular disease in people under investigation

Activity recognition in smart environments is an evolving research problem due to the advancement and proliferation of sensing, monitoring and actuation technologies to make it possible for large scale and real deployment. While activities in smart home are interleaved, complex and volatile; the number of inhabitants in the environment is also dynamic. A key challenge in designing robust smart home activity recognition approaches is to exploit the users' spatiotemporal behavior and location, focus on the availability of multitude of devices capable of providing different dimensions of information and fulfill the underpinning needs for scaling the system beyond a single user or a home environment. In this paper, we propose a hybrid approach for recognizing complex activities of daily living (ADL), that lie in between the two extremes of intensive use of body-worn sensors and the use of ambient sensors. Our approach harnesses the power of simple ambient sensors (e.g., motion sensors) to provide additional 'hidden' context (e.g., room-level location) of an individual, and then combines this context with smartphone-based sensing of micro-level postural/locomotive states. The major novelty is our focus on multi-inhabitant environments, where we show how the use of spatiotemporal constraints along with multitude of data sources can be used to significantly improve the accuracy and computational overhead of traditional activity recognition based approaches such as coupled-hidden Markov models. Experimental results on two separate smart home datasets demonstrate that this approach improves the accuracy of complex ADL classification by over 30 %, compared to pure smartphone-based solutions.

2014-12-01

Full Text Available The aim of this paper is to discuss the ways in which objects assist us in telling small stories about our positions in relation to our inhabited space, but also in relation to perceived dichotomised categories like us-others, the modern-the outmoded, civilized-backward. Acknowledging that narratives emerge from interactions between people, this paper is an attempt to show that an important role in the emergence of stories is played by interactions between people and objects. The wall carpets hung by Ursari Roma from a north-eastern Romanian town and the stories developed with and about these items constitute the main focus of this analysis. From an anthropological and material culture perspective, wall carpets are discussed as material presences in storytelling events and as objects of experience-centred stories that assist Roma people in negotiating and enacting their identities and belongings. Taking a cue from Georgakopoulou, who argues that narratives count on both discourses and activities (2007, home making practices and domestic activities (such as those related to the maintenance of the wall carpets are essential to this paper, as they enable an understanding of the “performative narrative of daily life” (Langellier 2004. The analysis is based on ethnographic material collected in 2014 in the aforementioned community, while the unit of analysis consists of excerpts from discussions with two Roma families, which became storytelling episodes.

Polymorphism of HLA class II genes was studied in native Chukotka inhabitants with the use of DNA oligotyping. The characteristics of the distribution of allelic variants of the loci HLA-DRB1, -DQA1, -DQB1, and -DPB1 were revealed; they were similar to those of other Subarctic Mongoloid populations and different from those for comparable populations of other climatic and geographic zones. Our data suggest that the specific features found for the distributions of some alleles of the loci examined are related to the geographic variation in the HLA gene system studied. 20 refs., 4 tabs.

Full Text Available Međimurje County stands out as a developed and densely populated county of Central Croatia. Demographic and socio-economic developmental trends of Međimurje indicate the referred-to status: age structure, birth rates, population activity rates and share of jobs are significantly higher than the Croatian average. At the same time, Međimurje is home to one of the largest Croatian Roma communities, ethnically homogeneous and spatially isolated, whose predominantly unfavourable geographical features make the opposite developmental pole of previously described developed areas inhabited by the majority population. Development indicators at county level have omitted concrete living conditions of Roma. They inhabit the rural periphery characterized by social and spatial segregation, unemployment and existence on the margins of society and settlements. This paper provides an analysis of housing, economic and social functions of areas inhabited by Roma, as well as migratory trends and main functional orientation of these areas in Međimurje County. In so, the settlement of Kuršanec will be emphasized as a representative example of areas inhabited by Roma in Međimurje County.

Becker, Norbert; Oo, Thin Thin; Schork, Nino

2015-11-09

The control of container-inhabiting mosquitoes is mainly based on environmental management with special emphasis on community participation e.g. source reduction by elimination or modification of water bodies. However, citizens are often not aware of the problems related to urban mosquito control or just ignore the advice provided during anti-mosquito control campaigns. In particular, cemeteries contain favourite breeding sites for container-inhabiting mosquitoes like Ochlerotatus j. japonicus, Culex pipiens s.l./Cx. torrentium, Aedes aegypti or Aedes albopictus. In our study, we investigated whether metallic copper e.g. in form of copper spray can be a suitable and cost-effective tool to combat mosquito breeding in vases or other similar small containers where no commonly used insecticides can be applied. The effect of metallic copper spray in comparison to 5 Euro cent coins or copper tubes at different dosages and water qualities applied in small water collections such as widely used plastic grave vases were evaluated by assessing the mortality rates of larvae of Oc.j. japonicus, Cx. pipiens s.l./Cx. torrentium and Ae.aegypti. Different water qualities were tested to assess the influence of pH on the solubility of the copper ions. The copper concentrations were quantified using ICP/MS (Inductively coupled plasma/Mass spectrometry) in relation to the exposure time and mortality rates of mosquito larvae. All statistical analyses were computed using JMP 10.0.2 (SAS Institute Inc., 2012, Cary, NC, USA). Dosages of less than 500 ppb of copper in the water of small containers led to a 100% mortality rate after 2 weeks for all tested mosquito species by using one or more 5 Euro cent coins/vase. When the interior surface of plastic grave vases was covered by metallic copper spray, all of the tested larvae died after 7-10 days in the laboratory and under field conditions the reduction rate was 99.44% for Oc.j. japonicus and 99.6% for Culex pipiens s.l./Cx. torrentium

2011-01-01

Like many other mountain communities, people living in the peripheries of Khunjerab National Park (KNP) have been using plant resources for food, medicine, shelter, fuel and other purposes since long. The present study was carried out to record the most common medicinal and aromatic plants (MAPs) and their traditional uses by the local inhabitants from the study area. A total of 43 plant species belonging to 40 genera and 28 families were recorded from Dhee, Barkhun, Shimshal and Khunjerab pastures during field visits conducted in 2006-2008, which are being used by the people of the area for the preparation of herbal recipes. In all, Asteraceae family contributed the highest number of species (11.63%), followed by Fabaceae, Lamiaceae and Rosaceae (9.30% each), Chenopodiaceae and Elaeagnaceae (4.65% each). Twenty nine diseases were treated by the reported species. Maximum number of species were employed for treating fever (9 spp.), followed by cough, in digestion (5 spp. each), wounds, eye infection, abdominal pain, jaundice, blood pressure and diarrhea (4 spp. each). The study area is a fragile ecosystem which is rapidly degrading due to excessive grazing and over exploitation by the inhabitants for their customary needs. In order to protect the dwindling floral resources and their classical uses, concrete conservation measures i.e., education and awareness, integration of traditional knowledge with modern health care and ex situ conservation of threatened species, supporting local livelihoods and rural economy is inevitable.

The results of integral dose estimations for inhabitants of four settlements near the former Semipalatinsk nuclear test site obtained by EPR dosimetry on tooth enamel in 2004-2005 years are discussed. It was found that the observed dose distributions have a nonstandard bimodal form with a mode at low doses in the range from 0.3-0.5 Gy, and a tail with higher doses, possibly suggesting two subpopulations. Possible reasons for such high doses are discussed.

Food Neophobia in Wild Rats (Rattus norvegicus Inhabiting a Changeable Environment-A Field Study.

Directory of Open Access Journals (Sweden)

Klaudia Modlinska

Full Text Available Food neophobia is a reaction to novel food observed in many animal species, particularly omnivores, including Rattus norvegicus. A neophobic reaction is typically characterised by avoidance of novel food and the necessity to assess both its potential value and toxicity by the animal. It has been hypothesised that this reaction is not observed in rats inhabiting a changeable environment with a high level of variability with regard to food and food sources. This study was conducted in such changeable conditions and it aims to demonstrate the behaviour of wild rats R. norvegicus in their natural habitat. The rats were studied in a farm setting, and the experimental arena was demarcated by a specially constructed pen which was freely accessible to the rats. At regular intervals, the rats were given new flavour- and smell-altered foods, while their behaviour was video-recorded. The results obtained in the study seem to confirm the hypothesis that rats inhabiting a highly changeable environment do not exhibit food neophobia. The observed reaction to novel food may be connected with a reaction to a novel object to a larger extent than to food neophobia. The value of the results obtained lies primarily in the fact that the study was conducted in the animals' natural habitat, and that it investigated their spontaneous behaviours.

The feline skin microbiota: The bacteria inhabiting the skin of healthy and allergic cats

Background The skin is inhabited by a multitude of microorganisms. An imbalance of these microorganisms is associated with disease, however, the causal relationship between skin microbiota and disease remains unknown. To describe the cutaneous bacterial microbiota of cats and determine whether bacterial dysbiosis occurs on the skin of allergic cats, the skin surfaces on various regions of 11 healthy cats and 10 allergic cats were sampled. Methodology/Principal findings Genomic DNA was extracted from skin swabs and sequenced using primers that target the V4 region of the bacterial 16S rRNA. The bacterial sequences from healthy cats revealed that there are differences in species diversity and richness between body sites and different epithelial surfaces. Bacterial communities preferred body site niches in the healthy cats, however, the bacterial communities on allergic cat skin tended to be more unique to the individual cat. Overall, the number of bacterial species was not significantly different between the two health status groups, however, the abundances of these bacterial species were different between healthy and allergic skin. Staphylococcus, in addition to other taxa, was more abundant on allergic skin. Conclusions/Significance This study reveals that there are more bacterial species inhabiting the skin of cats than previously thought and provide some evidence of an association between dysbiosis and skin disease.

The soils analysis for radionuclides content determination in three inhabited areas of Near-Aral region (Shiili, Kazalinsk and Zhalagash) is carried out. In capacity of the 226 Ra, 232 Th, 40 K, 137 Cs, and radon concentrations analytical parameters were selected. A mean, minimal and maximal values of 226 Ra, 232 Th, 40 K, 137 Cs radioisotopes in the selected areas soils are presented. Results of radionuclide content researches testify about 137 Cs global fallout typical levels for the Northern Hemisphere. So on the base of these data one can affirm that radiation situation in these regions is normal and radiation background level does not presents threat for human health. The indoor radon content excluding of two points does not exceeds the stated norms

Saiki, Michael K.; Martin, Barbara A.; May, Thomas W.

2012-01-01

Resource managers are concerned that water conservation practices in irrigated farmlands along the southern border of the Salton Sea, Imperial County, California, could increase selenium concentrations in agricultural drainwater and harm the desert pupfish (Cyprinodon macularius), a federally protected endangered species. As part of a broader attempt to address this concern, we conducted a 3-year investigation to collect baseline information on selenium concentrations in seven agricultural drains inhabited by pupfish. We collected water, sediment, selected aquatic food-chain taxa (particulate organic detritus, filamentous algae, net plankton, and midge [Chironomidae] larvae), and two poeciliid fishes (western mosquitofish Gambusia affinis and sailfin molly Poecilia latipinna) for selenium determinations. The two fish species served as ecological surrogates for pupfish, which we were not permitted to sacrifice. Dissolved selenium ranged from 0.70 to 32.8 μg/L, with selenate as the major constituent. Total selenium concentrations in other environmental matrices varied widely among drains, with one drain (Trifolium 18) exhibiting especially high concentrations in detritus, 5.98–58.0 μg Se/g; midge larvae, 12.7–50.6 μg Se/g; mosquitofish, 13.2–20.2 μg Se/g; and mollies, 12.8–30.4 μg Se/g (all tissue concentrations are based on dry weights). Although toxic thresholds for selenium in fishes from the Salton Sea are still poorly understood, available evidence suggests that ambient concentrations of this element may not be sufficiently elevated to adversely affect reproductive success and survival in selenium-tolerant poeciliids and pupfish.

The two fish species served as ecological surrogates for pupfish, which we were not permitted to sacrifice. Dissolved selenium ranged from 0.70 to 32.8 μg/L, with selenate as the major constituent. Total selenium concentrations in other environmental matrices varied widely among drains, with one drain (Trifolium 18) exhibiting especially high concentrations in detritus, 5.98-58.0 μg Se/g; midge larvae, 12.7-50.6 μg Se/g; mosquitofish, 13.2-20.2 μg Se/g; and mollies, 12.8-30.4 μg Se/g (all tissue concentrations are based on dry weights). Although toxic thresholds for selenium in fishes from the Salton Sea are still poorly understood, available evidence suggests that ambient concentrations of this element may not be sufficiently elevated to adversely affect reproductive success and survival in selenium-tolerant poeciliids and pupfish.

Singular points in moduli spaces of Yang-Mills fields

1984-01-01

This thesis investigates the metric dependence of the moduli spaces of Yang-Mills fields of an SU(2) principal bundle P with chern number -1 over a four-dimensional, simply-connected, oriented, compact smooth manifold M with positive definite intersection form. The purpose of this investigation is to suggest that the surgery class of the moduli space of irreducible connections is, for a generic metric, a Z 2 topological invariant of the smooth structure on M. There are three main parts. The first two parts are local analysis of singular points in the moduli spaces. The last part is global. The first part shows that the set of metrics for which the moduli space of irreducible connections has only non-degenerate singularities has codimension at least one in the space of all metrics. The second part shows that, for a one-parameter family of moduli spaces in a direction transverse to the set of metrics for which the moduli spaces have singularities, passing through a non-degenerate singularity of the simplest type changes the moduli space by a cobordism. The third part shows that generic one-parameter families of metrics give rise to six-dimensional manifolds, the corresponding family of moduli spaces of irreducible connections. It is shown that when M is homeomorphic to S 4 the six-dimensional manifold is a proper cobordism, thus establishing the independence of the surgery class of the moduli space on the metric on M

Container-inhabiting Aedes are among the most medically important mosquito vectors of diseases. They also impact health and quality of life by their persistent and severe biting. Monitoring of container-inhabiting Aedes species is challenging due to the need for specialized traps and lures. Biogents Sentinel (BGS) trap has become a standard for Aedes albopictus (Skuse) surveillance; however, it has substantial problems with durability, quality of construction, and sample exposure to the elements. The goal of this study was to develop a methodology for collecting medically important container-inhabiting Aedes species in numbers sufficient for population trend analysis, control efficacy studies, and pathogen testing. Mosquito Magnets (MM) baited with BG lure and R-octenol were selected as the most practical alternative to BGS, collecting significantly more Ae. albopictus (32.1 ± 0.7 vs. 5.6 ± 0.1), Aedes japonicus (Theobald) (10.1 ± 0.4 vs. 1.2 ± 0.02), and Aedes triseriatus (Say) (0.9 ± 0.04 vs. 0.04 ± 0.004) females on average per trapping under a variety of weather conditions. MM can be particularly useful for long-term surveillance or when large numbers of specimens are required for pathogen isolation, such as at the sites with suspected dengue or chikungunya transmission. © The Authors 2015.

As a part of the China-Japan cooperative research on natural radiation epidemiology, we have carried out a dose-assessment study to evaluate the external exposure to natural radiation in the high background radiation areas (HBRA) of Yangjiang in Guangdong province and in the control areas (CA) of Enping prefecture since 1991. Because of the difficulties in measuring the individual doses of all inhabitants directly by personal dosimeters, an indirect method was applied in which the exposed individual doses were estimated from the environmental radiation doses measured by survey meters and the occupancy factors of each hamlet. We analyzed the dose in the hamlets and the variation in the occupancy factors to obtain the parameters of dose estimation on the inhabitants in selected hamlets; Madi and several hamlets of different dose levels in HBRA and Hampizai hamlet in CA. With these parameters, we estimated individual dose rates and compared them with those obtained from direct measurement using dosimeters carried by selected individuals. The results obtained are as follows. The environmental radiation doses are influenced by the natural radioactive nuclide concentrations in building materials, the age of the building and the arrangement of the houses in a hamlet. There existed a fairly large and heterogeneous distribution of indoor and outdoor environmental radiations. The indoor radiation doses were due to exposure from the natural radioactive nuclides in the building materials and were about two times as large as the outdoor radiation doses. The difference between indoor and outdoor doses was not observed in CA. The occupancy factor was influenced by the age of individuals and by the season of the year. The occupancy factor was higher for infants and aged individuals than for other age groups. This lead to higher dose rates of exposure to those age groups. A good correlation was observed between the dose assessed indirectly and that measured directly and the

Full Text Available Process of deindustrialization of downtowns in most of well-developed Western European countries has been undertaken since 1960’s while in post-socialist countries just from last 25 years, after political and economic transitions in Central and Eastern Europe.  As far as urban structure is concerned, a new type of inner-city sites has appeared as a consequence of the collapse of industrial activities in second half of 20th century.  In vast majority of cases newly developed morhological units (e.g. run-down post-industrial have been unavailable to the public. As a reult, “classical” public space organization of European cities has been significantly changed. However, revitalization of post-industrial urban areas creates opportunities to reorganize public space according to current inhabitants and other urban space users’ needs. All transitions undertaken as a part of re-developement of brownfields sites are focused on impovements in physical and functional dimension of urban space quality to increase the standard of living condition. According to the concept of smat cities it is relaeted to “smart living” in sustainable urban environment. As a matter of fact, post-socialist cities in Central and Eastern Europe where interval of central planning was present in second half of 20th century and “classical” capitalist cites of Western Europe represent different patterns of public space transitions due to distinct historical development process of central space. In the paper a comparative study of Manchester, Lyon and Łódź is presented. The aim of the research is to indicate the reorganization of historically shaped public space structre in central space of analyzed cities after revitalization of post-industrial urban areas and new central space creation.

The space shuttle program from challenge to achievement: Space exploration rolling on tires

The Space Shuttle Transportation System is the first space program to employ the pneumatic tire as a part of space exploration. For aircraft tires, this program establishes new expectations as to what constitutes acceptable performance within a set of tough environmental and operational conditions. Tire design, stresses the usual low weight, high load, high speed, and excellent air retention features but at extremes well outside industry standards. Tires will continue to be an integral part of the Shuttle's landing phase in the immediate future since they afford a unique combination of directional control, braking traction, flotation and shock absorption not available by other systems.

The objective of the present study was to monitor the levels of organochlorine pesticides HCB, α-β-γ-HCH, pp'DDE, op'DDT and pp'DDT in 150 adipose tissue samples of Veracruz, Mexico inhabitants. In analyzed samples, the following pesticides were detected: p,p'-DDE in 100% of the samples at mean 1.643 mg/kg; p,p'-DDT in 99.3.% of the samples at mean 0.227 mg/kg; β-HCH in 97.3% of the samples at mean 0.063 mg/kg; and op'DDT in 93.3% of the samples at mean 0.022 mg/kg. Comparing mean, median and geometric mean concentrations of organochlorine pesticides shows a decrease in values from mean to median and to geometric mean which points out a prevalence of lower concentrations among the total samples and the existence of occasional cases of extreme exposure expressed in range values. The pooled samples divided according to sex, showed only significant differences of pp'DDE median concentrations between sexes. The other organochlorine pesticides indicated no statistical differences between sexes, including the pp'DDE/pp'DDT ratio. The samples grouped according to age, showed that the third tertile was more contaminated for both sexes, indicating age as a positively associated factor with organochlorine pesticide levels in adipose tissue of Veracruz inhabitants. Comparing organochlorine pesticide levels between 2008 and 2010 years, a decreased tendency for β-HCH, pp'DDE, Σ-DDT and pp'DDE/pp'DDT ratio levels was observed.

NASA's Goddard Space Flight Center (GSFC) is adapting current data networking technologies to fly on future spaceflight missions. The benefits of using commercially based networking standards and protocols have been widely discussed and are expected to include reduction in overall mission cost, shortened integration and test (I&T) schedules, increased operations flexibility, and hardware and software upgradeability/scalability with developments ongoing in the commercial world. The networking effort is a comprehensive one encompassing missions ranging from small University Explorer (UNEX) class spacecraft to large observatories such as the Next Generation Space Telescope (NGST). Mission aspects such as flight hardware and software, ground station hardware and software, operations, RF communications, and security (physical and electronic) are all being addressed to ensure a complete end-to-end system solution. One of the current networking development efforts at GSFC is the SpaceLAN (Spacecraft Local Area Network) project, development of a space-qualifiable Ethernet network. To this end we have purchased an IEEE 802.3-compatible 10/100/1000 Media Access Control (MAC) layer Intellectual Property (IP) core and are designing a network node interface (NNI) and associated network components such as a switch. These systems will ultimately allow the replacement of the typical MIL-STD-1553/1773 and custom interfaces that inhabit most spacecraft. In this paper we will describe our current Ethernet NNI development along with a novel new space qualified physical layer that will be used in place of the standard interfaces. We will outline our plans for development of space qualified network components that will allow future spacecraft to operate in significant radiation environments while using a single onboard network for reliable commanding and data transfer. There will be a brief discussion of some issues surrounding system implications of a flight Ethernet. Finally, we will

We investigated the interaction between fungal communities of soil and dead wood substrates. For this, we applied molecular species identification and stable isotope tracking to both soil and decaying wood in an unmanaged boreal Norway spruce-dominated stand. Altogether, we recorded 1990 operational taxonomic units, out of which more than 600 were shared by both substrates and 589 were found to exclusively inhabit wood. On average the soil was more species-rich than the decaying wood, but the species richness in dead wood increased monotonically along the decay gradient, reaching the same species richness and community composition as soil in the late stages. Decaying logs at all decay stages locally influenced the fungal communities from soil, some fungal species occurring in soil only under decaying wood. Stable isotope analyses suggest that mycorrhizal species colonising dead wood in the late decay stages actively transfer nitrogen and carbon between soil and host plants. Most importantly, Piloderma sphaerosporum and Tylospora sp. mycorrhizal species were highly abundant in decayed wood. Soil- and wood-inhabiting fungal communities interact at all decay phases of wood that has important implications in fungal community dynamics and thus nutrient transportation.

The manifold model for space-time

International Nuclear Information System (INIS)

Heller, M.

1981-01-01

Physical processes happen on a space-time arena. It turns out that all contemporary macroscopic physical theories presuppose a common mathematical model for this arena, the so-called manifold model of space-time. The first part of study is an heuristic introduction to the concept of a smooth manifold, starting with the intuitively more clear concepts of a curve and a surface in the Euclidean space. In the second part the definitions of the Csub(infinity) manifold and of certain structures, which arise in a natural way from the manifold concept, are given. The role of the enveloping Euclidean space (i.e. of the Euclidean space appearing in the manifold definition) in these definitions is stressed. The Euclidean character of the enveloping space induces to the manifold local Euclidean (topological and differential) properties. A suggestion is made that replacing the enveloping Euclidean space by a discrete non-Euclidean space would be a correct way towards the quantization of space-time. (author)

Life in a rock pool: Radiation and population genetics of myxozoan parasites in hosts inhabiting restricted spaces.

Intertidal rock pools where fish and invertebrates are in constant close contact due to limited space and water level fluctuations represent ideal conditions to promote life cycles in parasites using these two alternate hosts and to study speciation processes that could contribute to understanding the roles of parasitic species in such ecosystems. Gall bladder and liver samples from five clinid fish species (Blenniiformes: Clinidae) were morphologically and molecularly examined to determine the diversity, prevalence, distribution and host specificity of Ceratomyxa parasites (Cnidaria: Myxozoa) in intertidal habitats along the coast of South Africa. Phylogenetic relationships of clinid ceratomyxids based on the SSU rDNA, LSU rDNA and ITS regions were assessed additionally to the investigation of population genetic structure of Ceratomyxa cottoidii and subsequent comparison with the data known from type fish host Clinus cottoides. Seven Ceratomyxa species including previously described Ceratomyxa dehoopi and C. cottoidii were recognized in clinids. They represent a diverse group of rapidly evolving, closely related species with a remarkably high prevalence in their hosts, little host specificity and frequent concurrent infections, most probably as a result of parasite radiation after multiple speciation events triggered by limited host dispersal within restricted spaces. C. cottoidii represents the most common clinid parasite with a population structure characterized by young expanding populations in the south west and south east coast and by older populations in equilibrium on the west coast of its distribution. Parasite and fish host population structures show overlapping patterns and are very likely affected by similar oceanographic barriers possibly due to reduced host dispersal enhancing parasite community differentiation. While fish host specificity had little impact on parasite population structure, the habitat preference of the alternate invertebrate host as

In this paper we provide a criterion of essential self-adjointness for operators in the tensor product of a separable Hilbert space and a Fock space. The class of operators we consider may contain a self-adjoint part, a part that preserves the number of Fock space particles and a non-diagonal part that is at most quadratic with respect to the creation and annihilation operators. The hypotheses of the criterion are satisfied in several interesting applications

The paper presents the results of research on closed-life support systems initiated during a system design study on space colonization and concentrates on the water and waste water components. Metabolic requirements for the 10,000 inhabitants were supplied by an assumed earth-like diet from an intensive agriculture system. Condensed atmospheric moisture provided a source of potable water and a portion of the irrigation water. Waste water was reclaimed by wet oxidation. The dual-water supply required the condensation of 175 kg/person-day of atmospheric water and the processing of 250 kg/person-day of waste water.

The objective of this research was to find out the continuity of seuramoe keu, tungai/rambat, and seuramoe likeut (three fundamental spaces in rumoh Aceh) in three development stages of houses since 1980 until present time. The development starts from the stilt house (santeut), non-stilt house, up to the contemporary house. In the period in which modern life has an impact in changing people lifestyles and then affects the mindset of the need for spaces, the study of the continuity of the three spaces mentioned reflects how far the culture of the people of Aceh in the past persist today, considering architecture, including spaces, is the reflection of the socio-cultural of inhabitants/community. The study was conducted by observing the spaces on seven sample houses and by interviewing the house owners to find out the factors that affect the existence/non-existence of spaces. The results showed that the three spaces (seuramoe keu, tungai, and seuramoe likeut) undergone the continuity despite the differences occurred in the interior compared to rumoh Aceh, meanwhile the continuity factor was based on the culture of life that is still firmly held by Acehnese.

In late October 1995, I found a remarkable message on my answering machine from Ed Weiler, then the Program Scientist for the Hubble Space Telescope. Would I work on the next generation space telescope, the successor to the beautiful HST? It took me mere moments to work out the answer: Of course! At the time, my work on the COsmic Background Explorer (COBE) was finished, I was writing a book about it (The Very First Light, with John Boslough), and I thought NASA might never do anything nearly as spectacular again. Wow, was I happy to be surprised by that call!

Faussot, Nicolas; Cottreau, Yann; Hardy, Guillaume; Simonpietri, Pascal; Gaiffe, Thierry

2017-11-01

Among the technologies available for gyroscopes usable in space, the Fibre Optic Gyroscope (FOG) technology appears to be the most suitable: no moving parts, very good lifetime, low power consumption, very low random walk, arbitrarily low angular resolution and very good behaviour in radiations and vacuum. Benefiting from more than ten years of experience with this technology, Ixsea (formerly the Navigation Division of Photonetics) is developing space FOG under both CNES and ESA contracts since many years. In the 1996-1998 period, two space FOG demonstrators in the 0,01°/h class were manufactured, including an optical head (optic and optoelectronic part) designed for space use and a standard ground electronics. Beyond the demonstration of the specified FOG performances, the behaviour of the optical head has been validated for use in typical space environment: vibrations, shocks, radiations (up to 50 krad) and thermal vacuum. Since the beginning of 1999, Ixsea is developing a space electronics in order to manufacture two complete space FOG. The first one entered in qualification in October. The second one will be delivered beginning of next year, it will be used in a CNES attitude measurement experiment (MAGI) onboard the FrenchBrazilian Microsatellite (FBM) partly dedicated to technology evaluation.

Mirilas, Petros; Skandalakis, John E

2009-11-01

Embryologically, the retroperitoneal (extraperitoneal) connective tissue includes three strata, which respectively form the internal fascia lining of the body wall, the renal fascia, and the covering of the gastrointestinal viscera. All organs, vessels, and nerves, that lie on the posterior abdominal wall, along with their tissues and surrounding connective and fascial planes, are collectively referred to as the retroperitoneum. The retroperitoneal space is the area of the posterior abdominal wall that is located between the parietal peritoneum and the fascia. Within the greater retroperitoneal space, there are also several small spaces, or subcompartments. Loose connective tissue and fat surround the anatomic entities, and, to a variable degree, occupy the subcompartments. The multilaminar thoracolumbar (lumbodorsal) fascia begins at the occipital area and terminates at the sacrum.

Fundamental plant biology enabled by the space shuttle.

The relationship between fundamental plant biology and space biology was especially synergistic in the era of the Space Shuttle. While all terrestrial organisms are influenced by gravity, the impact of gravity as a tropic stimulus in plants has been a topic of formal study for more than a century. And while plants were parts of early space biology payloads, it was not until the advent of the Space Shuttle that the science of plant space biology enjoyed expansion that truly enabled controlled, fundamental experiments that removed gravity from the equation. The Space Shuttle presented a science platform that provided regular science flights with dedicated plant growth hardware and crew trained in inflight plant manipulations. Part of the impetus for plant biology experiments in space was the realization that plants could be important parts of bioregenerative life support on long missions, recycling water, air, and nutrients for the human crew. However, a large part of the impetus was that the Space Shuttle enabled fundamental plant science essentially in a microgravity environment. Experiments during the Space Shuttle era produced key science insights on biological adaptation to spaceflight and especially plant growth and tropisms. In this review, we present an overview of plant science in the Space Shuttle era with an emphasis on experiments dealing with fundamental plant growth in microgravity. This review discusses general conclusions from the study of plant spaceflight biology enabled by the Space Shuttle by providing historical context and reviews of select experiments that exemplify plant space biology science.

2017-05-01

Full Text Available Background The study of ancient microorganisms in mineralized dental plaque or calculi is providing insights into microbial evolution, as well as lifestyles and disease states of extinct cultures; yet, little is still known about the oral microbial community structure and function of pre-Columbian Caribbean cultures. In the present study, we investigated the dental calculi microbiome and predicted function of one of these cultures, known as the Saladoid. The Saladoids were horticulturalists that emphasized root-crop production. Fruits, as well as small marine and terrestrial animals were also part of the Saladoid diet. Methods Dental calculi samples were recovered from the archaeological site of Sorcé, in the municipal island of Vieques, Puerto Rico, characterized using 16S rRNA gene high-throughput sequencing, and compared to the microbiome of previously characterized coprolites of the same culture, as well modern plaque, saliva and stool microbiomes available from the Human Microbiome Project. Results Actinobacteria, Proteobacteria and Firmicutes comprised the majority of the Saladoid dental calculi microbiome. The Saladoid dental calculi microbiome was distinct when compared to those of modern saliva and dental plaque, but showed the presence of common inhabitants of modern oral cavities including Streptococcus sp., Veillonella dispar and Rothia mucilaginosa. Cell motility, signal transduction and biosynthesis of other secondary metabolites may be unique features of the Saladoid microbiome. Discussion Results suggest that the Saladoid dental calculi microbiome structure and function may possibly reflect a horticulturalist lifestyle and distinct dietary habits. Results also open the opportunity to further elucidate oral disease states in extinct Caribbean cultures and extinct indigenous cultures with similar lifestyles.

Tesei, Donatella; Marzban, Gorji; Zakharova, Kristina; Isola, Daniela; Selbmann, Laura; Sterflinger, Katja

2012-01-01

Rock inhabiting fungi are among the most stress tolerant organisms on Earth. They are able to cope with different stressors determined by the typical conditions of bare rocks in hot and cold extreme environments. In this study first results of a system biological approach based on two-dimensional protein profiles are presented. Protein patterns of extremotolerant black fungi – Coniosporium perforans, Exophiala jeanselmei – and of the extremophilic fungus – Friedmanniomyces endolithicus – were compared with the cosmopolitan and mesophilic hyphomycete Penicillium chrysogenum in order to follow and determine changes in the expression pattern under different temperatures. The 2D protein gels indicated a temperature dependent qualitative change in all the tested strains. Whereas the reference strain P. chrysogenum expressed the highest number of proteins at 40 °C, thus exhibiting real signs of temperature induced reaction, black fungi, when exposed to temperatures far above their growth optimum, decreased the number of proteins indicating a down-regulation of their metabolism. Temperature of 1 °C led to an increased number of proteins in all of the analysed strains, with the exception of P. chrysogenum. These first results on temperature dependent reactions in rock inhabiting black fungi indicate a rather different strategy to cope with non-optimal temperature than in the mesophilic hyphomycete P. chrysogenum.

The concentrations of radon-222 in the air of some buildings in Olsztyn were measured. The main source of radon in buildings is in general the ground under building and the materials used for building structure. In this work the results of radon-222 concentration measurements in the air of some buildings constructed before the 1939 year, in the buildings constructed after 1945 year with the traditional use of the bricks and in the buildings constructed with the use of great prefabricated plates are presented. The relations between radon-222 concentrations in the basements and in the first floor flats situated above the basement were evaluated. Based on the mean radon concentrations in the air of the various types of buildings investigated the effective doses for the inhabitants of each type of buildings were estimated. (author)

Dung-inhabiting fungi: a potential reservoir of novel secondary metabolites for the control of plant pathogens.

Sarrocco, Sabrina

2016-04-01

Coprophilous fungi are a large group of saprotrophic fungi mostly found in herbivore dung. The number of these fungi undergoing investigation is continually increasing, and new species and genera continue to be described. Dung-inhabiting fungi play an important ecological role in decomposing and recycling nutrients from animal dung. They produce a large array of bioactive secondary metabolites and have a potent enzymatic arsenal able to utilise even complex molecules. Bioactive secondary metabolites are actively involved in interaction with and defence against other organisms whose growth can be inhibited, resulting in an enhanced ecological fitness of producer strains. Currently, these antibiotics and bioactive secondary metabolites are of interest in medicine in particular, while very little information is available concerning their potential use in agriculture. This review introduces the ecology of dung-inhabiting fungi, with particular emphasis on the production of antibiotic compounds as a means to compete with other microorganisms. Owing to the fast pace of technological progress, new approaches to predicting the biosynthesis of bioactive metabolites are proposed. Coprophilous fungi should be considered as elite candidate organisms for the discovery of novel antifungal compounds, above all in view of their exploitation for crop protection. © 2015 Society of Chemical Industry.

Full Text Available The present investigation aims to evaluate biomimetic synthesis of silver nanoparticles using endophytic bacterium EH 419 inhabiting Euphorbia hirta L. The synthesized nanoparticles were initially confirmed with change in color from the reaction mixture to brown indicating the synthesis of nanoparticles. Further confirmation was achieved with the characteristic absorption peak at 440 nm using UV-Visible spectroscopy. The synthesized silver nanoparticles were subjected to biophysical characterization using hyphenated techniques. The possible role of biomolecules in mediating the synthesis was depicted with FTIR analysis. Further crystalline nature of synthesized nanoparticles was confirmed using X-ray diffraction (XRD with prominent diffraction peaks at 2θ which can be indexed to the (111, (200, (220, and (311 reflections of face centered cubic structure (fcc of metallic silver. Transmission electron microscopy (TEM revealed morphological characteristics of synthesized silver nanoparticles to be polydisperse in nature with size ranging from 10 to 60 nm and different morphological characteristics such as spherical, oval, hexagonal, and cubic shapes. Further silver nanoparticles exhibited bactericidal activity against panel of significant pathogenic bacteria among which Pseudomonas aeruginosa was most sensitive compared to other pathogens. To the best of our knowledge, present study forms first report of bacterial endophyte inhabiting Euphorbia hirta L. in mediating synthesizing silver nanoparticles.

Air pollution around the Keihin heavy chemical industrial zone, and living environment and health injury in the inhabitants therein

Energy Technology Data Exchange (ETDEWEB)

Miyazaki, I

1975-08-01

A survey of air pollution levels and the health of high school pupils and their parents was conducted in a heavily industrialized area of Kawasaki, Japan. The concentration of sulfur oxides in 1974 was about half of that in 1970 (0.029 ppM). The concentration of nitrogen oxides ranged from 0.030 to 0.040 ppM. There was a correlation between the concentrations of oxides of sulfur nitrogen. According to questionnaires, about 32 percent of the inhabitants showed concern about air pollution and photochemical smog. About 22 percent of the inhabitants complained of symptoms such as cold, rhinitis, and pharyngitis; and there was a correlation between total subjective symptoms and concentration of sulfur oxides. Near roadsides the concentration of nitrogen oxides was very high. Green plants are gradually disappearing from the heavily polluted area. Further industrialization in this area appears to be very dangerous for man and other living things.

Weathering of radionuclides deposited in inhabited areas

Roed, J.; Andersson, K.G.; Togawa, O.

1996-01-01

When determining the long-term consequences of an accidental deposition of radionuclides from a nuclear power plant in an inhabited area it is essential to be able to predict the migration with time of the deposited radiocaesium. Through the years that have passed since the Chernobyl accident occurred in 1986, the weathering effects on deposited radiocaesium on different types of surface in urban, suburban and industrial areas have been followed through six measurement campaigns to the Gaevle area of Sweden. The weathering effects after the Chernobyl accident were also investigated in towns in the Ukraine and in Russia. The radiocaesium level on asphalt and concrete pavements was found to decrease rather rapidly. It was found that the weathering effects over the first decade could be described by a double exponential function. Similar analytical functions were derived for the other urban surfaces. However, the weathering half-lives of radiocaesium on walls and roofs of buildings were found to be much longer. Even in urban centres, the largest contribution to the dose-rate immediately after deposition often comes from the open grassed areas and areas of soil. As the dose-rate from such surfaces usually decreases slowly, depending on the soil type, the relative importance of these surfaces will often increase with time. After a decade, the dose-rate from horizontal pavements will decrease by a factor of 10 or more, but the dose-rate from an area of soil or a roof may only be halved. Correspondingly, the dose-rate from a wall decreases by only 10-20 %. (author)

Transcriptional Upregulation of DNA Damage Response Genes in Bank Voles (Myodes glareolus Inhabiting the Chernobyl Exclusion Zone

2018-01-01

Full Text Available Exposure to ionizing radiation (IR from radionuclides released into the environment can damage DNA. An expected response to exposure to environmental radionuclides, therefore, is initiation of DNA damage response (DDR pathways. Increased DNA damage is a characteristic of many organisms exposed to radionuclides but expression of DDR genes of wildlife inhabiting an area contaminated by radionuclides is poorly understood. We quantified expression of five central DDR genes Atm, Mre11, p53, Brca1, and p21 in the livers of the bank vole Myodes glareolus that inhabited areas within the Chernobyl Exclusion Zone (CEZ that differed in levels of ambient radioactivity, and also from control areas outside the CEZ (i.e., sites with no detectable environmental radionuclides in Ukraine. Expression of these DDR genes did not significantly differ between male and female bank voles, nor among sites within the CEZ. We found a near two-fold upregulation in the DDR initiators Mre11 and Atm in animals collected from the CEZ compared with samples from control sites. As Atm is an important regulator of oxidative stress, our data suggest that antioxidant activity may be a key component of the defense against exposure to environmental radioactivity.

2010-01-01

To determine the current risk of internal radiation exposure after the Chernobyl accident, the 137 Cs body burden of the inhabitants of Bryansk Oblast (Russian Federation) was evaluated, from 1998 to 2008. The study population is composed of 84 666 people who visited Bryansk No. 2 Hospital. A whole-body counter was used for measurement of 137 Cs body burden. 137 Cs concentration was significantly higher in the late period during the study and showed seasonal variation, suggesting that inhabitants may have consumed contaminated forest products. However, people with high annual exposure doses were quite rare during all years of the study. In conclusion, although internal radiation exposure from 137 Cs continues to this day in Bryansk Oblast, the annual exposure dose is low in almost all inhabitants. Because of the long half-life of 137 Cs, the long term follow-up is necessary to monitor the health status and relieve the anxiety of the inhabitants around Chernobyl. (authors)

2017-07-01

Full Text Available This paper focuses upon a place called the Vertical Village, a building in the center of Rio de Janeiro inhabited exclusively by indigenous peoples from different ethnic groups belonging to different parts of the country. In this paper, we discuss questions related to the experience of being indigenous in a city, the construction of a residential space as a village, and the constitution of indigenous identity in the urban context. Following the paths of three inhabitants of the building, the questions considered emerge from their transiting between cities and villages, frontiers either real or imaginary, prejudices and expectations of indigenous identity.

Heterogeneity and Developmental Connections between Cell Types Inhabiting Teeth

Directory of Open Access Journals (Sweden)

Jan Krivanek

2017-06-01

Full Text Available Every tissue is composed of multiple cell types that are developmentally, evolutionary and functionally integrated into the unit we call an organ. Teeth, our organs for biting and mastication, are complex and made of many different cell types connected or disconnected in terms of their ontogeny. In general, epithelial and mesenchymal compartments represent the major framework of tooth formation. Thus, they give rise to the two most important matrix–producing populations: ameloblasts generating enamel and odontoblasts producing dentin. However, the real picture is far from this quite simplified view. Diverse pulp cells, the immune system, the vascular system, the innervation and cells organizing the dental follicle all interact, and jointly participate in transforming lifeless matrix into a functional organ that can sense and protect itself. Here we outline the heterogeneity of cell types that inhabit the tooth, and also provide a life history of the major populations. The mouse model system has been indispensable not only for the studies of cell lineages and heterogeneity, but also for the investigation of dental stem cells and tooth patterning during development. Finally, we briefly discuss the evolutionary aspects of cell type diversity and dental tissue integration.

Vital Space in the House of Buendía

Directory of Open Access Journals (Sweden)

Nina M. Scott

1984-01-01

Full Text Available In terms of both narrative and thematic organization, Gabriel Garcia Márquez's One Hundred Years of Solitude deals with tightly-closed structures. Whereas from the beginning Macondo has been interpreted in a variety of ways, critics have paid less attention to the meaning of the Buendía house itself. A close reading of the text shows that the way in which certain characters interact with the physical spaces of the house is highly symbolic and closely related to the thematic development of the entire novel. The rise and fall of the Buendía dynasty is presided over by three women, who function as the rulers of the house: Ursula, Fernanda and Amaranta Ursula. Each one of them affects the architecture of the structure, but as the house increasingly has a life of its own, is in turn shaped by the dwelling itself. The fall of the Buendía family is reflected in the loss of control not only of the lives of certain characters, but of the vital spaces within the house that they inhabit.

Space imagination and mixed identity in Russian towns bordering on Finland

2014-11-01

Full Text Available The quantitative analysis of an opinion poll conducted in October 2013 in three Russian cities located near Finnish border (St-Petersburg, Kronstadt and Vyborg explores European identity of their citizens. This area was chosen to illustrate the crucial importance of space interpretation in spatial identity formation by using critical geopolitical approach. The study shows how different images of space on the same territory act as intermediate variables between objective territorial characteristics and citizens’ identities. As the geographical position at the border of Russia provides the citizens with geopolitical alternatives to identify their location as a fortress defending the nation (as in the case of Kronstadt or a bridge between cultures, the given study allows us to compare reasons for these geopolitical choices of inhabitants. Furthermore, the research aims at bridging the gap in the studies of European and multiple identity in Russian regions and provides Northwest Russian perspective on the perpetual discussion about subjective Eastern border of Europe.

2004-01-01

Objective: The purposes is to estimate the average annual effective dose of the inhabitants and absorbed dose in some human tissues and organs arising from natural radiation sources in the High Background Radiation Area (HBRA) of Yangjiang and in the neighboring Control Area (CA). In order to provide more effective evidence for analyzing the dose-effect relationships among the cohort members in the investigated areas, authors divided the local inhabitant into different dose-groups. Methods: The authors measured the environmental gamma external radiation levels and individual accumulated doses of 5293 people in the investigated areas. The concentrations for 222 Rn, 220 Rn and their decay products in air were also surveyed. The authors estimated the internal doses of natural radionuclides based on the results obtained from measurements in food, in drinking water, in human teeth, in several human tissues, in human placenta, and in activity concentration of exhaled 222 Rn and 220 Rn of the residents living in the investigated areas. Results: The estimation of average annual effective doses in HBRA and CA based on the data of environmental measurements of radiation level respectively are 2.12 ± 0.29 mSv a -1 and 0.69 ± 0.09 mSv a -1 . The sources of higher background radiation in HBRA are mainly contributed from terrestrial gamma radiation. The estimation of average annual effective doses to the residents arising from inhalation of 222 Rn, 220 Rn and their decay products was 3.28 mSv a -1 in HBRA, while that in CA was 1.03 mSv a -1 . The values of the absorbed dose of the residents in their trachea-bronchial tree and lung in HBRA arising from inhalation of 222 Rn, 220 Rn and their decay products are 5.40 mGy a -1 and 1.08 mGy a -1 respectively, which are about four times of the values of the absorbed dose in CA. The estimation of average annual effective doses to the inhabitants caused by 226 Ra and 228 Ra in HBRA and CA were 281.88 μSv a -1 and 84.54 μSv a -1

Space Elevators: Building a Permanent Bridge for Space Exploration and Economic Development

Smitherman, David V., Jr.; Howell, Joe T. (Technical Monitor)

2000-01-01

A space elevator is a physical connection from the surface of the Earth to a geo-stationary orbit above the Earth approximately 35,786 km in altitude. Its center of mass is at the geo-stationary point such that it has a 24-hour orbit, and stays over the same point above the equator as the Earth rotates on its axis. The structure is utilized as a transportation and utility system for moving payloads, power, and gases between the surface of the Earth and space. It makes the physical connection from Earth to space in the same way a bridge connects two cities across a body of' water. The space elevator may be an important concept for the future development of space in the latter part of the 21th century. It has the potential to provide mass-transportation to space in the same way highways, railroads, power lines, and pipelines provide mass-transportation across the Earth's surface. The low energy requirements for moving payloads up and down the elevator make it one of only a few concepts that has the potential of lowering the cost to orbit to less than $10 per kilogram. This paper will summarize the findings from a 1999 NASA workshop on Space Elevators held at the NASA Marshall Space Flight Center (MSFC). The workshop was sponsored by the Advanced Projects Office in the Flight Projects Directorate at MSFC, and was organized in cooperation with the Advanced Space Transportation Program at MSFC and the Advanced Concepts Office in the Office of Space Flight at NASA Headquarters. New concepts will be examined for space elevator construction and a number of issues will be discussed that has helped to bring the space elevator concept out of the realm of science fiction and into the realm of possibility. In conclusion, it appears that the space elevator concept may well he possible in the latter part of the 21st century if proper planning and technology development is emphasized to resolve key issues in the development of this advanced space infrastructure concept.

Higher spin currents in Wolf space. Part I

2014-03-20

For the N=4 superconformal coset theory described by ((SU(N+2))/(SU(N))) (that contains a Wolf space) with N=3, the N=2 WZW affine current algebra with constraints is obtained. The 16 generators of the large N=4 linear superconformal algebra are described by those WZW affine currents explicitly. By factoring out four spin-(1/2) currents and the spin-1 current from these 16 generators, the remaining 11 generators (spin-2 current, four spin-(3/2) currents, and six spin-1 currents) corresponding to the large N=4 nonlinear superconformal algebra are obtained. Based on the recent work by Gaberdiel and Gopakumar on the large N=4 holography, the extra 16 currents, with spin contents (1,(3/2),(3/2),2), ((3/2),2,2,(5/2)), ((3/2),2,2,(5/2)), and (2,(5/2),(5/2),3) described in terms of N=2 multiplets, are obtained and realized by the WZW affine currents. As a first step towards N=4W algebra (which is NOT known so far), the operator product expansions (OPEs) between the above 11 currents and these extra 16 higher spin currents are found explicitly. It turns out that the composite fields with definite U(1) charges, made of above (11+16) currents (which commute with the Wolf space subgroup SU(N=3)×SU(2)×U(1) currents), occur in the right hand sides of these OPEs.

This 'natural' phasing allows the entire refrigerator to operate with only one moving part (the loudspeaker diaphragm). A space-qualified thermoacoustic refrigerator was flown on the Space Shuttle Discovery (STS-42) in January, 1992. It was entirely autonomous, had no sliding seals, required no lubrication, used mostly low-tolerance machined parts, and contained no expensive components. Thermoacoustics is shown to be a competitive candidate for food refrigerator/freezers and commercial/residential air conditioners. The design and performance of the Space Thermo/Acoustic Refrigerator (STAR) is described.

Fauna, flora, fowl, and fruit: effects of the Columbian Exchange on the allergic response of New and Old World inhabitants.

Science.gov (United States)

Salvaggio, J E

1992-01-01

The Columbian Exchange has been described as "the most important event in human history since the end of the Ice Age." This interchange of many species of fauna, flora, fowl, and fruits resulted in new encounters between New and Old World inhabitants. Prominent among these were manifestations of allergic reactions to many of the new substances. Little imagination is required to reflect on what these substances, added to or detracted from both the New and Old World lifestyles, habits, and diets. The numerous peas, vegetable seeds, and grasses, such as sugarcane, introduced during Columbus' later voyages, made an enormous difference in the lives of New World inhabitants, as did the introduction of the cow and horse, not to mention substances such as coconuts and bananas, that are now intimately associated with the Caribbean and the Bahamas. This article focuses on some the more important exchange substances and emphasizes many forms of anaphylaxis: asthma, food allergy, hypersensitivity pneumonitis, chronic bronchitis, rhinitis, serum sickness, and other conditions that developed in both New and Old World inhabitants. To mention only a few examples, the Europeans introduced to the New World potential dangers such as honeybees (anaphylaxis). It also gave the New World the cow and the horse (serum sickness), which became the constant companion of Columbus' Indians and the American cowboy. It gave the Italians their thick red gravy, and the New World its pizza (food allergy). The Caribbean received bananas and coconuts and the New World embraced coffee (caffeine addiction). On the other hand, the exchange also caused Europeans to begin puffing away on tobacco.

Overview of different information about acute radiation syndrome among inhabitants around Chernobyl

International Nuclear Information System (INIS)

Yaroshinskaya, A.

1998-01-01

The Chernobyl nuclear catastrophe has divided scientists of the world, studying the consequences of its impact on the health of people, into two opposed, at times irreconcilable blocks. The first block generally comprises representatives of medical officials in the soviet and post-soviet society. They have been concealing the truth from the soviet and the world public for years. This group advocates the point of view that, except for firemen and several staff members who died at the time of the catastrophe, the Chernobyl accident has produced no practical impact on human health and will not do any such effect also in future. The second block consists basically of independent scientists. They are anxious about the facts of concealment of the truth on actual radiation doses, received by inhabitants of the areas around the Chernobyl NPP (ChNPP), as well as about impacts of low radiation dose on human health. Scientists of the second block are convinced that doses received by the population in the first days and months after the catastrophe at the ChNPP have played and will play significantly negative roles in worsening of human health years after the accident. The data on these doses have been deliberately concealed by the authorities from both the sufferers and the public. This fact has been already proven (by the Procurator General of the Ukraine as well). I have official and unofficial documents in my Chernobyl archive, which are demonstrating two approaching ways to the problems of radiological consequences due to the Chernobyl catastrophe. I would like to emphasize that these documents have never been published anywhere. In searching the answer to the question about the acute radiation syndrome among inhabitants in the areas around the Chernobyl NPP in the first weeks and months after the catastrophe, we will compare positions, arguments and conclusions of two blocks based on the facts presented in these documents.

Roman, Monsi C.; Mittelman, Marc W.

2010-01-01

The design and manufacturing of the main Environmental Control and Life Support Systems (ECLSS) for the United States segments of the International Space Station (ISS) was an involved process that started in the mid 1980s, with the assessment and testing of competing technologies that could be used to clean the air and recycle water. It culminated in 2009 with the delivery and successful activation of the Water Recovery System (WRS) water processor (WP). The ECLSS required the work of a team of engineers and scientist working together to develop systems that could clean and/or recycle human metabolic loads to maintain a clean atmosphere and provide the crew clean water. One of the main goals of the ECLSS is to minimize the time spent by the crew worrying about vital resources not available in the vacuum of space, which allows them to spend most of their time learning to live in a microgravity environment many miles from the comforts of Earth and working on science experiments. Microorganisms are a significant part of the human body as well as part of the environment that we live in. Therefore, the ISS ECLSS design had to take into account the effect microorganisms have on the quality of stored water and wastewater, as well as that of the air systems. Hardware performance issues impacted by the accumulation of biofilm and/or microbiologically influenced corrosion were also studied during the ECLSS development stages. Many of the tests that were performed had to take into account the unique aspects of a microgravity environment as well as the challenge of understanding how to design systems that could not be sterilized or maintained in a sterile state. This paper will summarize the work of several studies that were performed to assess the impacts and/or to minimize the effects of microorganisms in open, semi-closed and closed loop life support system. The biofilm and biodeterioration studies that were performed during the design and test periods will be presented in

The Nishiyama area, Nagasaki Prefecture has been known by that the black rain fell after dropping atomic bomb. The abnormal increase of the leukocyte number was measured in the inhabitants of Nishiyama area, Nagasaki Prefecture after dropping atomic bomb. This phenomenon differs from the general knowledge that the leukocyte number decreases by the radiation exposure. This has been noticed as a rare record confirmed by the residual radiation effect to the human body using the group data. (M.H.)

ASSESSMENT OF NOISE POLLUTION OF INHABITED TERRITORIES IMPACTED BY AIRFIELDS

Directory of Open Access Journals (Sweden)

Sazonov Eduard Vladimirovich

2012-10-01

Full Text Available In the article, authors provide an overview of effective regulatory, reference and technical documents that govern the extent of suitability of territories adjacent to airfields for building-up. Methods of assessing the acceptable limits of the aviation noise in the areas adjacent to airfields are considered in the article. Ecologization of airfield environs is not a new problem. The research described in the article is noteworthy for the proposed optimization of any plans for the assurance of habitability of specific areas impacted by noise pollutions. The optimization consists in a set of organizational and technical solutions based on the noise levels in specific areas, development planning conditions of inhabited areas, and the monitoring of the airfield environs. It is the multi-factor approach that is capable of resolving the problem of ecological stress imposed by the noise coming from the air transport. Towards this end, the problem-solving strategy is to be developed and implemented in the areas that feature the same unfavorable environmental characteristics.

The mathematics of the modernist villa architectural analysis using space syntax and isovists

CERN Document Server

Ostwald, Michael J

2018-01-01

This book presents the first detailed mathematical analysis of the social, cognitive and experiential properties of Modernist domestic architecture. The Modern Movement in architecture, which came to prominence during the first half of the twentieth century, may have been famous for its functional forms and machine-made aesthetic, but it also sought to challenge the way people inhabit, understand and experience space. Ludwig Mies van der Rohe’s buildings were not only minimalist and transparent, they were designed to subvert traditional social hierarchies. Frank Lloyd Wright’s organic Modernism not only attempted to negotiate a more responsive relationship between nature and architecture, but also shape the way people experience space. Richard Neutra’s Californian Modernism is traditionally celebrated for its sleek, geometric forms, but his intention was to use design to support a heightened understanding of context. Glenn Murcutt’s pristine pavilions, seemingly the epitome of regional Modernism, actu...

Urban Function of the Infraordinary

The spaces of the city that we pass through daily are worn half invisible by use. Often, we are more concerned with the extraordinary than its opposite—what Georges Perec coined the infraordinary. This paper seeks to uncover the unheeded spaces of dry cleaners as a place of social coexistence......-)events unfold, trajectories thicken, and people of the neighbourhood coexist as familiar strangers through events in real time and deposits over time. It is a semi-public space and an implosion of the external neighbourhood, partly through allowing for occupation, inhabitation, and co-authoring. These latent...

Wood, B. E.

2007-01-01

This report describes the results of an NRA funded program entitled Space Environmental Effects Knowledgebase that received funding through a NASA NRA (NRA8-31) and was monitored by personnel in the NASA Space Environmental Effects (SEE) Program. The NASA Project number was 02029. The Satellite Contamination and Materials Outgassing Knowledgebase (SCMOK) was created as a part of the earlier NRA8-20. One of the previous tasks and part of the previously developed Knowledgebase was to accumulate data from facilities using QCMs to measure the outgassing data for satellite materials. The main object of this current program was to increase the number of material outgassing datasets from 250 up to approximately 500. As a part of this effort, a round-robin series of materials outgassing measurements program was also executed that allowed comparison of the results for the same materials tested in 10 different test facilities. Other programs tasks included obtaining datasets or information packages for 1) optical effects of contaminants on optical surfaces, thermal radiators, and sensor systems and 2) space environmental effects data and incorporating these data into the already existing NASA/SEE Knowledgebase.

Biometry of neotropical invertebrates inhabiting floodplain rivers: unraveling bionomy

Directory of Open Access Journals (Sweden)

Florencia Zilli

Full Text Available ABSTRACT Currently, it is widely recognized that invertebrates play key roles in neotropical floodplains and in many other environments worldwide. However, little information has been published concerning their biometry, in spite that it represents an essential tool for many different studies. Here, we provided length-mass and length-length relationships by fitting the linearized model (log10 Y = log10a + b log10 X and several mean biomass ratios ± SE for bivalves, gastropods, quironomids, ephemeropterans, oligochaetes and hirudineans. We measured, weighed, oven dried and incinerated to ashes specimens collected from 2005 to 2014 in the Paraná River, Argentina. The lineal equations had fit levels higher than 75% in most of the significant regressions. Hence, when slopes were compared, differences raised from ontogeny and phylogeny of taxa. Additionally, slopes resulted different from constants of other regions, types of environments and climates. In addition, organic matter ratios resulted significantly different among invertebrates according to their feeding types. The equations and ratios that we provided will facilitate future research on life history, productivity and energy transference in the food webs of invertebrates inhabiting floodplain wetlands and can be used as tools for planning management strategies and in restoration projects of aquatic environments.

Development of a Methodology to Conduct Usability Evaluation for Hand Tools that May Reduce the Amount of Small Parts that are Dropped During Installation while Processing Space Flight Hardware

Science.gov (United States)

Miller, Darcy

2000-01-01

Foreign object debris (FOD) is an important concern while processing space flight hardware. FOD can be defined as "The debris that is left in or around flight hardware, where it could cause damage to that flight hardware," (United Space Alliance, 2000). Just one small screw left unintentionally in the wrong place could delay a launch schedule while it is retrieved, increase the cost of processing, or cause a potentially fatal accident. At this time, there is not a single solution to help reduce the number of dropped parts such as screws, bolts, nuts, and washers during installation. Most of the effort is currently focused on training employees and on capturing the parts once they are dropped. Advances in ergonomics and hand tool design suggest that a solution may be possible, in the form of specialty hand tools, which secure the small parts while they are being handled. To assist in the development of these new advances, a test methodology was developed to conduct a usability evaluation of hand tools, while performing tasks with risk of creating FOD. The methodology also includes hardware in the form of a testing board and the small parts that can be installed onto the board during a test. The usability of new hand tools was determined based on efficiency and the number of dropped parts. To validate the methodology, participants were tested while performing a task that is representative of the type of work that may be done when processing space flight hardware. Test participants installed small parts using their hands and two commercially available tools. The participants were from three groups: (1) students, (2) engineers / managers and (3) technicians. The test was conducted to evaluate the differences in performance when using the three installation methods, as well as the difference in performance of the three participant groups.

Relativistic meson spectroscopy in momentum space

International Nuclear Information System (INIS)

Hersbach, H.

1994-01-01

In this paper a relativistic constituent-quark model based on the Ruijgrok--de Groot formalism is presented. The quark model is not defined in configuration space, but in momentum space. The complete meson spectrum, with the exception of the self-conjugate light unflavored mesons, is calculated. The potential used consists of a one-gluon exchange (OGE) part and a confining part. For the confining part a relativistic generalization of the linear plus constant potential was used, which is well defined in momentum space without introducing any singularities. For the OGE part several potentials were investigated. Retardations were included at all places. By the use of a fitting procedure involving 52 well-established mesons, but results were obtained for a potential consisting of a purely vector Richardson potential and a purely scalar confining potential. Reasonable results were also obtained for a modified Richardson potential. Most meson masses, with the exception of the π, the K, and the K 0 * , were found to be quite well described by the model

2012-01-01

Full Text Available Bringing the trilogy of the Erasmus intensive programme together in 2010, the Faculty of Architecture organised the third workshop in the series “Designing and Inhabiting Virtual Environments - DIVE”, addressing an elusive issue: “Bridging the gap between the physical and virtual” with the reference site of Križanke. During the 10-day intensive workshop, the participants developed a theoretical discussion based on a series of lectures, and afterwards pursued analyses of the reference site and designed spatial interventions with an emphasis on respecting the fragile nature of the site. From the very beginning to the end of their work, the participants analysed the boundaries between physical and virtual reality, examined the pros and cons of each, and sought possible integrations of both entities within a seamless and effective conceptual and actual representation.

Assessment of daily intake of major and trace elements by inhabitants of potential radiation protection of greater Cairo area, Egypt

International Nuclear Information System (INIS)

Ramadan, A.B.

2005-01-01

Concentrations of K, Ca, U, Th, Cs, Sr, I, Al, Cd, Cu, Mn, Pb, Ni and Cr were determined in vegetables, common foodstuffs and some animal products consumed by adult inhabitants of Greater Cairo Area. Some of these elements have chemical and biological similarity to some of the radionuclides abundantly encountered during nuclear power production and therefore data on these elements could provide important information on their biokinetic behavior. A total of 120 samples were analyzed using Neutron Activation Analysis (NAA) and Atomic Absorption Spectrometry (AAS). Generally, highest contributions for the intake of micro nutrients (Cu, Mn and Ni) arise from broad bean, rice and wheat flour consumption. Meat, milk, eggs and some vegetables are the major sources of K, Ca, U, Th, Cs, Al, Cd and Pb. The medium daily intake for the adult inhabitants of greater Cairo area was found to be 1.98 g of K, 0.54 mg of Ca, 1.14 fig of U, 0.8 μg of Th, 5.2μg of Cs, 1.3 mg of Sr, 105 μg of 1, 3.2 mg of Mn, 0.9 mg of Cu, 5.7 mg of Al, 5, 2 x 10 -2 mg of Pb, 2.1x10 -3 mg of Cd, 7.7x10 -2 mg of Ni and 2.1 x 10 -2 mg of Cr. The lower daily intake of Ca, Th, Cs and I by adult inhabitants of greater Cairo area could be due to the significantly lower consumption of milk and milk products, which are rich in these elements. The significantly lower intake of calcium by adult inhabitants of greater Cairo area may lead to higher uptake of radiostrontium and could result in higher internal radiation dose. The use of highly sensitive and reliable analytical methods resulted in accurate assessment of the values recorded for thorium and uranium suggested that radiation dose from their ingestion at natural background levels, is likely to be lower than those included in ICRP data. Concerning micro nutrients, the recommended values of daily intake of Cu and Mn are conveniently supplied by the common diet; however for Cr is lower than the recommended daily allowance. Due to high metals concentrations

Fathivand, A.A.; Asefi, M.; Amidi, A.

2005-01-01

Full text: A knowledge of natural radioactivity in man and his environment is important since naturally occurring radionuclides are the major source of radiation exposure to man. Radioactive nuclides present in the natural environment enter the human body mainly through food and water.Besides, measurement of naturally occurring radionuclides in the environment can be used not only as a reference when routine releases from nuclear installation or accidental radiation exposures are assessed, but also as a baseline to evaluate the impact caused by non-nuclear activities. In Iran, measurement of natural and artificial radionuclides in environmental samples in normal and high-background radiation areas have been performed by some investigators but no information has been available on 226 Ra and 228 Ra in foodstuffs. Therefore we have started measurements of 226 Ra and 228 Ra in foodstuffs of Ramsar which is a coastal city in the north part of Iran and has been known as one of the world's high level natural radiation areas, using low level gamma spectrometry measurement system .The results from our measurements and food consumption rates for inhabitants of Ramsar city have been used for the estimation of annual effective dose due to consumption of foodstuffs by inhabitants of Ramsar city. A total of 33 samples from 11 different foodstuffs including root vegetables (beetroot), leafy vegetables (lettuce, parsley and spinach) and tea, meat,chicken, pea,broad bean, rice, and cheese were purchased from markets and were analyzed for their 226 Ra and 228 Ra concentrations. The highest concentrations of 226 Ra and 228 Ra were determined in tea samples with 1570 and 1140 mBq kg -1 respectively and the maximum estimated annual effective dose from 226 Ra and Ra due to consumption foodstuffs were determined to be 19.22 and 0.71 μSv from rice and meat samples respectively

2006-01-01

This study documents the investigation of qualitative habitability and human factors feedback provided by scientists, engineers, and crewmembers on lessons learned from the ISS Program. A thorough review and understanding of this data is critical in charting NASA's future path in space exploration. NASA has been involved in ensuring that the needs of crewmembers to live and work safely and effectively in space have been met throughout the ISS Program. Human factors and habitability data has been collected from every U.S. crewmember that has resided on the ISS. The knowledge gained from both the developers and inhabitants of the ISS have provided a significant resource of information for NASA and will be used in future space exploration. The recurring issues have been tracked and documented; the top 5 most critical issues have been identified from this data. The top 5 identified problems were: excessive onsrbit stowage; environment; communication; procedures; and inadequate design of systems and equipment. Lessons learned from these issues will be used to aid in future improvements and developments to the space program. Full analysis of the habitability and human factors data has led to the following recommendations. It is critical for human factors to be involved early in the design of space vehicles and hardware. Human factors requirements need to be readdressed and redefined given the knowledge gained during previous ISS and long-duration space flight programs. These requirements must be integrated into vehicle and hardware technical documentation and consistently enforced. Lastly, space vehicles and hardware must be designed with primary focus on the user/operator to successfully complete missions and maintain a safe working environment. Implementation of these lessons learned will significantly improve NASA's likelihood of success in future space endeavors.

Full Text Available Background: The concept of the quality of life (HRQOL related to health and its determinants contain aspects of quality of life that clearly affect people’s physical or mental health. One of the newest ways to assess the health and also the quality of life-related to health is the self-assessed health of the individual. The aim of the present study was assessment of unhealthy days, self-reported health status, and its influencing factors on residents of the marginalpart of Mashhad, Iran. Methods: In the current cross-sectional study, 580 citizens of the marginal regions and slum areas of Mashhad city were enrolled through cluster sampling method using governmental health care services divisions. The Persian version of the questionnaire CDC HRQOL-4 was used to measure the unhealthy days. Data was analyzed using SPSS, version 11.5, running ANOVA, chi-square, and t-tests. P-value of less than 0.05 was considered as statistically significant. Results: In the present study, 359 persons (61% were women and the mean age of participants was 32.6±11.51 years. The means of unhealthy days, physically unhealthy days, mentally unhealthy days, and days with dysfunction were found to be 7.2, 2.8, 4.1, and 1.7 days, respectively. The unhealthiest days (physical and mental were seen in unemployed people and the best to excellent health days were seen in housewives. Conclusion: Unhealthy days and days with dysfunction were reported higher in slum inhabitants, especially female, low literacy, and housewife participants. Providing the education and employment facilities for people who live in marginal city areas might decrease the unhealthy days.Keywords: Unhealthy days; Health; Urban Marginal Inhabitants; Mashhad

Since 1990 the effective doses from external and internal irradiation to residents in the Bryansk area, Russia, have been followed. In the 1990s field surveys in a number of villages took place annually and after 1998 more irregularly. All surveys were carried out in September-October, The individual doses of the inhabitants were assessed using TL-dosemeters and 'in vivo' measurements of 134 , 137 Cs. Twenty years after the Chernobyl accident, the average effective dose rate from internal and external exposure of 137 Cs to the inhabitants of the surveyed settlements - due to Chernobyl - was estimated to 0.6 mSv year -1 . This additional dose contribution is comparable with the yearly dose from cosmic radiation and naturally occurring radionuclides in the human body. During the first three years of the survey (1990-1993), the temporal variation in the effective dose rate from external irradiation can be described by a 20% annual decrease and then slowing down to a 12% decrease per year up to 1998. After that, there is a much slower decrease. In 2006 the fraction of the total effective dose rate associated with external exposure, was in the order of 0.4 mSv year -1 , which is twice as high as the dose from exposure of internal 137 Cs sources. The temporal variation in the internal exposure of 134 , 137 Cs is much more complex and related to several environmental and social factors. Hence, large variations are observed during different years and also between villages and within a specific village. In the present paper, results from all the field surveys are compared and the temporal evolution of the radiation environment during 20 years is discussed. (author)

Sampling Indoor Aerosols on the International Space Station

Meyer, Marit E.

In a spacecraft cabin environment, the size range of indoor aerosols is much larger and they persist longer than on Earth because they are not removed by gravitational settling. A previous aerosol experiment in 1991 documented that over 90 of the mass concentration of particles in the NASA Space Shuttle air were between 10 m and 100 m based on measurements with a multi-stage virtual impactor and a nephelometer (Liu et al. 1991). While the now-retired Space Shuttle had short duration missions (less than two weeks), the International Space Station (ISS) has been continually inhabited by astronauts for over a decade. High concentrations of inhalable particles on ISS are potentially responsible for crew complaints of respiratory and eye irritation and comments about 'dusty' air. Air filtration is the current control strategy for airborne particles on the ISS, and filtration modeling, performed for engineering and design validation of the air revitalization system in ISS, predicted that PM requirements would be met. However, aerosol monitoring has never been performed on the ISS to verify PM levels. A flight experiment is in preparation which will provide data on particulate matter in ISS ambient air. Particles will be collected with a thermophoretic sampler as well as with passive samplers which will extend the particle size range of sampling. Samples will be returned to Earth for chemical and microscopic analyses, providing the first aerosol data for ISS ambient air.

Perception of local inhabitants regarding the socioeconomic impact of tourism focused on provisioning wild dolphins in Novo Airao, Central Amazon, Brazil

Full Text Available Botos (Inia geoffrensis are currently provisioned for use in tourist attractions in five sites in the Brazilian Amazon. Despite the known negative effects associated with human-wild dolphin interactions, this activity has been regulated and licensed in the Anavilhanas National Park in Novo Airão, Amazonas State, Brazil. We present an updated evaluation of the perception of the local community concerning the possible socioeconomic impacts of this tourism in Novo Airão. In April 2011, 45 interviews were conducted with inhabitants. A small segment of Novo Airão perceives currently itself as being economically dependent on the botos feeding tourism. Despite that, the economic benefits of this controversial activity apparently are not shared among most inhabitants, and botos feeding tourism is perceived as generating diverse negative effects. We conclude that if the activity was banned or modified into a less impacting tourist activity, this action would probably not majorly affect the lives of the general population.

Space Weather and Global Climate Impacts are critical items on the present national and international science agendas. Understanding and forecasting solar activity is increasingly important for manned space flight, unmanned missions (including communications satellites, satellites that monitor the space and earth environment), and regional power grids. The ability to predict the effects of forcings and feedback mechanisms on global and local climate is critical to survival of the inhabitants of planet Earth. It is therefore important to motivate students to continue their studies via advanced degrees and pursue careers related to these areas. This CUNY-based initiative, supported by NASA and NSF, provided undergraduate research experience for more than 70 students in topics ranging from urban impacts of global climate change to magnetic rope structure, solar flares and CMEs. Other research topics included investigations of the ionosphere using a CubeSat, stratospheric aerosols in Jupiter's atmosphere, and ocean climate modeling. Mentors for the primarily summer research experiences included CUNY faculty, GISS and GSFC scientists. Students were recruited from CUNY colleges as well as other colleges including Spelman, Cornell, Rutgers and SUNY colleges. Fifty-eight percent of the undergraduate students were under-represented minorities and thirty-four percent were female. Many of the research teams included high school teachers and students as well as graduate students. Supporting workshops for students included data analysis and visualization tools, space weather, planetary energy balance and BalloonSats. The project is supported by NASA awards NNX10AE72G and NNX09AL77G, and NSF REU Site award 0851932.

Vastchenko, S. V.

2000-01-01

The anonymous questionnaire of the inhabitants living in various regions of Belarus and having different age and level of education ha been done. The poll has been carried out aiming at definition of a general radiation erudition, as well as revealing the knowledge of the population about the effect of power stations (nuclear and thermal) on the environment and the health of a human being. The analysis of answers shows that people have a rather vague idea in the sphere considered. The analysis of the questionnaires shows that women are informed worse than men about the problems on radiation subjects. The investigation carried out has shown what problems on nuclear power (and radiation safety) should be given the more serious consideration when working with population, especially with women's audience, in order to raise the level of accepting nuclear power as the necessary source of energy.

2011-04-01

Research on cranial suture biology suggests there is biological and taxonomic information to be garnered from the heritable pattern of suture synostosis. Suture synostosis along with brain growth patterns, diet, and biomechanical forces influence phenotypic variability in cranial vault morphology. This study was designed to determine the pattern of ectocranial suture synostosis in skeletal populations from the Aleutian Islands. We address the hypothesis that ectocranial suture synostosis pattern will differ according to cranial vault shape. Ales Hrdlicka identified two phenotypes in remains excavated from the Aleutian Island. The Paleo-Aleutians, exhibiting a dolichocranic phenotype with little prognathism linked to artifacts distinguished from later inhabitants, Aleutians, who exhibited a brachycranic phenotype with a greater amount of prognathism. A total of 212 crania representing Paleo-Aleuts and Aleutian as defined by Hrdlicka were investigated for suture synostosis pattern following standard methodologies. Comparisons were performed using Guttmann analyses. Results revealed similar suture fusion patterns for the Paleo-Aleut and Aleutian, a strong anterior to posterior pattern of suture fusion for the lateral-anterior suture sites, and a pattern of early termination at the sagittal suture sites for the vault. These patterns were found to differ from that reported in the literature. Because these two populations with distinct cranial shapes exhibit similar patterns of suture synostosis it appears pattern is independent of cranial shape in these populations of Homo sapiens. These findings suggest that suture fusion patterns may be population dependent and that a standardized methodology, using suture fusion to determine age-at-death, may not be applicable to all populations.

2018-03-01

Post conflict and tsunami; the city of Banda Aceh is experiencing a massive development as an effort to represent an Islamic city. Some strategic points have been chosen by the municipality to build architectural objects that are considered to represent Islam in the urban space. The issue of such representational practice is the development of neglecting the activities of local communities as users of urban public spaces. The purpose of this design study is to provide an alternative to the urban design of Banda Aceh to represent Islam that is not moving from physical development but by involving community activities. Establish and rediscover the relationship between Islam and urban life in Banda Aceh. This design study uses mental maps of 50 inhabitants of Banda Aceh city of various ages who live in 10 villages around the city center. We use mental maps as a tool to read the daily activities of the community and determine the familiar urban territory with the community. The results of this study will be used to form a Muslim community and present community activities to represent Islam in the urban space.

Earthquakes in El Salvador: a descriptive study of health concerns in a rural community and the clinical implications, part I.

Woersching, Joanna C; Snyder, Audrey E

2003-01-01

This is the first article in a series that evaluates the health concerns of people living in a Salvadoran rural community after major earthquakes. Part I reviews the background, methods, and results of post-earthquake conditions with regards to healthcare, access to healthcare, housing, food, water and sanitation. Part II reviews the implications of these results and recommendations for improvements within the community. Part III investigates the psychosocial and mental health consequences of the earthquakes and provides suggestions for improved mental health awareness, assessment, and intervention. El Salvador experienced 2 major earthquakes in January and February 2001. This study evaluates the effects of the earthquakes on the health practices in the rural town of San Sebastian. The research was conducted with use of a convenience sample survey of subjects affected by the earthquakes. The sample included 594 people within 100 households. The 32-question survey assessed post-earthquake conditions in the areas of health care and access to care, housing, food and water, and sanitation. Communicable diseases affected a number of family members. After the earthquakes, 38% of households reported new injuries, and 79% reported acute exacerbations of chronic illness. Rural inhabitants were 30% more likely to have an uninhabitable home than were urban inhabitants. Concerns included safe housing, water purification, and waste elimination. The findings indicate a need for greater public health awareness and community action to adapt living conditions after a disaster and prevent the spread of communicable disease.

National Space Agencies vs. Commercial Space: Towards Improved Space Safety

Pelton, J.

2013-09-01

assume that thiscondition will not change. This seems particularly true for high profile, multi-billion dollar programs.The second part of the paper focuses on new commercial space programs that appear to be undertaken in a less restrictive manner; i.e. outside the constraints of politically-driven national space policies. Here the drivers—even within international consortia—seem to be on reliable performance and commercial return. Since sustained accident-free performance is critical to commercial programs very existence and profitability, the inherent role of safety in commercial space industry would seem clear. The question of prime interest for this paper is whether or not it might be possible for smaller and more focused commercial space entities, free from the constraints of space agency organizational and political constraints, to be more "risk adverse" and thus be more nimble in designing "safe" vehicles? If so how can this "safety first" corporate philosophy and management practice be detected and even objectively measured? Could, in the future, risk reduction at the level of design, quality verification, etc., be objectively measured?

Belowground communication: impacts of volatile organic compounds (VOCs) from soil fungi on other soil-inhabiting organisms.

Science.gov (United States)

Werner, Stephanie; Polle, Andrea; Brinkmann, Nicole

2016-10-01

We reviewed the impact of fungal volatile organic compounds (VOCs) on soil-inhabiting organisms and their physiological and molecular consequences for their targets. Because fungi can only move by growth to distinct directions, a main mechanism to protect themselves from enemies or to manipulate their surroundings is the secretion of exudates or VOCs. The importance of VOCs in this regard has been significantly underestimated. VOCs not only can be means of communication, but also signals that are able to specifically manipulate the recipient. VOCs can reprogram root architecture of symbiotic partner plants or increase plant growth leading to enlarged colonization surfaces. VOCs are also able to enhance plant resistance against pathogens by activating phytohormone-dependent signaling pathways. In some cases, they were phytotoxic. Because the response was specific to distinct species, fungal VOCs may contribute to regulate the competition of plant communities. Additionally, VOCs are used by the producing fungus to attack rivaling fungi or bacteria, thereby protecting the emitter or its nutrient sources. In addition, animals, like springtails, nematodes, and earthworms, which are important components of the soil food web, respond to fungal VOCs. Some VOCs are effective repellents for nematodes and, therefore, have applications as biocontrol agents. In conclusion, this review shows that fungal VOCs have a huge impact on soil fauna and flora, but the underlying mechanisms, how VOCs are perceived by the recipients, how they manipulate their targets and the resulting ecological consequences of VOCs in inter-kingdom signaling is only partly understood. These knowledge gaps are left to be filled by future studies.

Full Text Available Background. The prevalence rates of food- and waterborne parasitic infections in Afghanistan are unknown. Cases of invasive diseases found in Afghans are rarely laboratory-confirmed. Objectives . The aim of the study was to present the current status of intestinal parasitic infections in Afghan inhabitants on the example of patients hospitalized in two healthcare facilities in eastern Afghanistan. Material and methods . Fecal samples were collected from 548 patients (children aged 1–17 years and adults with internal complaints, treated in Ghazni Provincial Hospital (Afghan civilian medical center, Ghazni province, 180 south-west of Kabul and in Bagram Korean Hospital (Korean military medical center for Afghan patients, Parwan province, 60 km north of Kabul between 2013 and 2014. One to three stool specimens from Afghan patients were fixed in 10% formalin, transported to the Military Institute of Medicine in Poland and tested by light microscopy using three diagnostic methods (direct smear in Lugol’s solution, decantation in distilled water and Fülleborn’s flotation. Results . Intestinal parasites were found in 144/386 of tested patients from the Ghazni province (37.3% infected, mainly with Ascaris lumbricoides , Giardia intestinalis , Hymenolepis nana and in 49/162 patients from the Parwan province (30.2% infected, mainly with G. intestinalis , A. lumbricoides , H. nana . Conclusions . The rates of intestinal parasitic infections among Afghans are high. The wide range of the detected parasites (protozoa, nematodes, cestodes should result in the introduction of general screening to be conducted regularly among inhabitants of Afghanistan and the application of targeted antiparasitic chemotherapy aiming to eliminate intestinal helminths and protozoa from the local community.

2012-01-01

As technological innovations produce new capabilities, complexities, and interdependencies, our susceptibility to the societal impacts of space weather increase. There is real concern in the scientific community that our infrastructure would be at significant risk if a major geomagnetic storm should occur. To discuss the societal impacts of space weather, we brought together an interdisciplinary group of subject matter experts and societal stakeholders to participate in a workshop entitled Space Weather Risks and Society. The workshop was held at Ames Research Center (ARC) on 15-16 October 2011. The workshop was co-sponsored by NASA Ames Research Center (ARC), the Lockheed Martin Advanced Technology Center (LMATC), the Space Weather Prediction Center (SWPC, part of the National Oceanic and Atmospheric Administration NOAA), and the Rutherford Appleton Laboratory (RAL, part of the UK Science and Technology Facilities Council STFC). The workshop is part of a series of informal weekend workshops hosted by Center Director Pete Worden.

Heavy metal exposure, reproductive activity, and demographic patterns in white-footed mice (Peromyscus leucopus) inhabiting a contaminated floodplain wetland

International Nuclear Information System (INIS)

Levengood, Jeffrey M.; Heske, Edward J.

2008-01-01

We examined the concentrations of selected metals and selenium (Se) in the tissues of white-footed mice (Peromyscus leucopus) collected at a constructed wetland originally created as a retention basin for sediments dredged from Lake DePue, Illinois. These sediments were contaminated with high concentrations of cadmium (Cd), zinc (Zn), and other elements as a result of nearby smelting operations. White-footed mice inhabiting the former retention basin experienced greater exposure to Cd, Pb, and Se than those from nearby reference sites. Concentrations of Cu and Zn in livers of mice from the contaminated wetland and adjacent floodplain reference site were greater than in mice from the more-distant reference sites. Judging by concentrations in their kidneys, white-footed mice inhabiting the floodplain adjacent to the contaminated wetland had greater exposure to Cd than those from the two more-distant reference sites. Concentrations of Hg in tissues of mice did not vary appreciably among sites. Concentrations of Cd and Se in the tissues of some white-footed mice from the contaminated wetland exceeded critical concentrations observed in experimental studies of laboratory mice and rats; with few exceptions tissue Pb concentrations were below published effects levels. However, we did not detect changes in abundance, demographics, or reproductive activity that might suggest population-level effects of contaminant exposure. Mean weight of embryos expressed as a function of crown-rump length did not differ among locations sampled, and no gross lesions indicative of exposure to heavy metals were observed. Kidney and liver weight, corrected for body weight, were nominally, though not significantly, lowest in both male and female mice from areas of increased Cd and Pb exposure. Metals dredged from Lake DePue were still bioavailable 25 years after deposition. However, small mammal populations are resilient to environmental stressors and we did not detect differences in

Technical and Economical study of New Technologies and Reusable Space Vehicles promoting Space Tourism.

Science.gov (United States)

Srivastav, Deepanshu; Malhotra, Sahil

2012-07-01

For many of us space tourism is an extremely fascinating and attractive idea. But in order for these to start we need vehicles that will take us to orbit and bring us back. Current space vehicles clearly cannot. Only the Space Shuttle survives past one use, and that's only if we ignore the various parts that fall off on the way up. So we need reusable launch vehicles. Launch of these vehicles to orbit requires accelerating to Mach 26, and therefore it uses a lot of propellant - about 10 tons per passenger. But there is no technical reason why reusable launch vehicles couldn't come to be operated routinely, just like aircraft. The main problem about space is how much it costs to get there, it's too expensive. And that's mainly because launch vehicles are expendable - either entirely, like satellite launchers, or partly, like the space shuttle. The trouble is that these will not only reduce the cost of launch - they'll also put the makers out of business, unless there's more to launch than just a few satellites a year, as there are today. Fortunately there's a market that will generate far more launch business than satellites ever well - passenger travel. This paper assesses this emerging market as well as technology that will make space tourism feasible. The main conclusion is that space vehicles can reduce the cost of human transport to orbit sufficiently for large new commercial markets to develop. Combining the reusability of space vehicles with the high traffic levels of space tourism offers the prospect of a thousandfold reduction in the cost per seat to orbit. The result will be airline operations to orbit involving dozens of space vehicles, each capable of more than one flight per day. These low costs will make possible a rapid expansion of space science and exploration. Luckily research aimed at developing low-cost reusable launch vehicles has increased recently. Already there are various projects like Spaceshipone, Spaceshiptwo, Spacebus, X-33 NASA etc. The

Computed tomography of the nasopharynx and related spaces. Part II: pathology

Malignant tumors of the nasopharynx were analyzed by region of origin and route of spread. Nasopharyngeal carcinomas produced early submucosal infiltration of the deglutitional muscle layer with enlargement of the levator palati muscle and lateral displacement of the parapharyngeal space. Serious otitis media was frequently associated, and the trigeminal nerve was occasionally involved. Intracranial extension via the foramen lacerum was frequent. Metastases to the infratemporal fossa produced early involvement of the masticatory muscle layer with medial displacement of the parapharygeal space. Adenoid cystic carcinomas showed late but disproportionate involvement of the sphenoid sinus. Chordomas extended into the retropharyngeal soft tissues via the petro-occipital fissure. Maxillary sinus carcinomas, which were very large at the time of presentation and impinged on the nasopharynx, showed extensive destruction of the pterygoid plates

Period mappings with applications to symplectic complex spaces

CERN Document Server

Kirschner, Tim

2015-01-01

Extending Griffiths’ classical theory of period mappings for compact Kähler manifolds, this book develops and applies a theory of period mappings of “Hodge-de Rham type” for families of open complex manifolds. The text consists of three parts. The first part develops the theory. The second part investigates the degeneration behavior of the relative Frölicher spectral sequence associated to a submersive morphism of complex manifolds. The third part applies the preceding material to the study of irreducible symplectic complex spaces. The latter notion generalizes the idea of an irreducible symplectic manifold, dubbed an irreducible hyperkähler manifold in differential geometry, to possibly singular spaces. The three parts of the work are of independent interest, but intertwine nicely.

The indigenous bacteria create natural cohabitation niches together with mucosal Abs in the gastrointestinal (GI) tract. Here we report that opportunistic bacteria, largely Alcaligenes species, specifically inhabit host Peyer's patches (PPs) and isolated lymphoid follicles, with the associated preferential induction of antigen-specific mucosal IgA Abs in the GI tract. Alcaligenes were identified as the dominant bacteria on the interior of PPs from naïve, specific-pathogen-free but not from germ-free mice. Oral transfer of intratissue uncultured Alcaligenes into germ-free mice resulted in the presence of Alcaligenes inside the PPs of recipients. This result was further supported by the induction of antigen-specific Ab-producing cells in the mucosal (e.g., PPs) but not systemic compartment (e.g., spleen). The preferential presence of Alcaligenes inside PPs and the associated induction of intestinal secretory IgA Abs were also observed in both monkeys and humans. Localized mucosal Ab-mediated symbiotic immune responses were supported by Alcaligenes-stimulated CD11c(+) dendritic cells (DCs) producing the Ab-enhancing cytokines TGF-beta, B-cell-activating factor belonging to the TNF family, and IL-6 in PPs. These CD11c(+) DCs did not migrate beyond the draining mesenteric lymph nodes. In the absence of antigen-specific mucosal Abs, the presence of Alcaligenes in PPs was greatly diminished. Thus, indigenous opportunistic bacteria uniquely inhabit PPs, leading to PP-DCs-initiated, local antigen-specific Ab production; this may involve the creation of an optimal symbiotic environment on the interior of the PPs.

Epithermal neutron activation analysis (ENAA) has been applied to studying elemental composition of Cr(VI)-reducer bacteria isolated from polluted basalts from the Republic of Georgia. Cr(VI)-reducing ability of the bacteria was examined by electron spin resonance (ESR) demonstrating that the bacteria differ in the rates of Cr(VI) reduction. A well-pronounced correlation between the ability of the bacteria to accumulate Cr(V) and their ability to reduce Cr(V) to Cr(III) observed in our experiments is discussed. Elemental analysis of these bacteria also revealed that basalt-inhabiting bacteria are distinguished by relative contents of essential elements such as K, Na, Mg, Fe, Mn, Zn, and Co. A high rate of Cr(III) formation correlates with a high concentration of Co in the bacterium. ENAA detected some similarity in the elemental composition of the bacteria. The relatively high contents of Fe detected in the bacteria (140-340 $\\mu $g/g of dry weight) indicate bacterial adaptation to the environmental condition...

Physics of the Space Environment

Vasyliünas, Vytenis M.

This book, one in the Cambridge Atmospheric and Space Science Series, joins a growing list of advanced-level textbooks in a field of study and research known under a variety of names: space plasma physics, solar-terrestrial or solar-planetary relations, space weather, or (the official name of the relevant AGU section) space physics and aeronomy. On the basis of graduate courses taught by the author in various departments at the University of Michigan, complete with problems and with appendices of physical constants and mathematical identities, this is indeed a textbook, systematic and severe in its approach. The book is divided into three parts, in length ratios of roughly 6:4:5. Part I, “Theoretical Description of Gases and Plasmas,” starts by writing down Maxwell's equations and the Lorentz transformation (no nonsense about any introductory material of a descriptive or historical nature) and proceeds through particle orbit theory, kinetics, and plasma physics with fluid and MHD approximations to waves, shocks, and energetic particle transport. Part II, “The Upper Atmosphere,” features chapters on the terrestrial upper atmosphere, airglow and aurora, and the ionosphere. Part III, “Sun-Earth Connection,” deals with the Sun, the solar wind, cosmic rays, and the terrestrial magnetosphere. The book thus covers, with two exceptions, just about all the topics of interest to Space Physics and Aeronomy scientists, and then some (the chapter on the Sun, for instance, briefly discusses also topics of the solar interior: thermonuclear energy generation, equilibrium structure, energy transfer, with a page or two on each). One exception reflects a strong geocentric bias: there is not one word in the main text on magnetospheres and ionospheres of other planets and their interaction with the solar wind (they are mentioned in a few problems). The other exception: the chapter on the terrestrial magnetosphere lacks a systematic exposition of the theory of

The algebraic approach to space-time geometry

A differential manifold can be defined in terms of smooth real functions carried by it. By rejecting the postulate, in such a definition, demanding the local diffeomorphism of a manifold to the Euclidean space, one obtains the so-called differential space concept. Every subset of R n turns out to be a differential space. Extensive parts of differential geometry on differential spaces, developed by Sikorski, are reviewed and adapted to relativistic purposes. Differential space as a new model of space-time is proposed. The Lorentz structure and Einstein's field equations on differential spaces are discussed. 20 refs. (author)

Nearly 40 years after the discovery of the Moessbauer effect for the first time a Moessbauer spectrometer will leave our planet to explore in situ the surface of another solar system body: the red planet Mars [1]. We are currently developing a miniaturized Moessbauer spectrometer (MIMOS) which is part of the scientific payload of the Russian Mars96 mission, to be launched within the next 2-4 years [2,3]. To fulfill the requirements for a space mission to the planet Mars, all parts of the spectrometer had to be extremely miniaturized and ruggedized to withstand the space flight and Mars environmental conditions. The relevant parts (e.g. drive, detector system, electronics etc.) will be described in more detail and its characteristics compared to standard systems. Because of this new development there now is a growing interest to include a Moessbauer (MB) instrument in future space missions to other solar system bodies as for instance Venus, the terrestrial Moon, and a comet nucleus. Because of extremely different environmental conditions (e.g. nearly zero gravity on the surface of a comet nucleus, high pressure and temperature on the surface of Venus, etc.) different instrument designs and concepts are required for different missions. We will present some ideas for various types of missions, as well as the motivation for using Moessbauer spectroscopy in these cases. (orig.)

The development of safe, reliable, and compact power systems is vital to humanity's exploration, development, and, ultimately, civilization of space. Nuclear power systems appear to present to offer the only practical option of compact high-power systems. From the very beginning of US space nuclear power activities, safety has been a paramount requirement. Assurance of nuclear safety has included prelaunch ground handling operations, launch, and space operations of nuclear power sources, and more recently serious attention has been given to postoperational disposal of spent or errant nuclear reactor systems. The purpose of this paper is to describe the progress of a project to utilize the capabilities of an evolving space infrastructure for planning for disposal of space nuclear systems. Project SIREN (Search, Intercept, Retrieve, Expulsion - Nuclear) is a project that has been initiated to consider post-operational disposal options for nuclear space power systems. The key finding of Project SIREN was that although no system currently exists to affect the disposal of a nuclear space power system, the requisite technologies for such a system either exist or are planned for part of the evolving space infrastructure

Carboxyhemoglobin levels for 1000 non-occupationally exposed inhabitants of Milan were determined. The study group consisted of smokers and non-smokers; among the former, only individuals refraining from smoking for at least 10 hr were tested. The upper limit of the normal range for HbCO values among non-smokers was 2.85%, while among heavy smokers it was 4.59%. Heavy smokers also showed higher HbCO levels than did moderate smokers. Elevated HbCO values were also observed among residents living in carbon monoxide-polluted urban areas as compared with those living in unpolluted rural areas.

This paper reviews scientific advances achieved by a North-South network between 2006 and 2016. These scientific advances concern solar terrestrial physics, atmospheric physics and space weather. This part B is devoted to the results and capacity building. Our network began in 1991, in solar terrestrial physics, by our participation in the two projects: International Equatorial Electrojet Year IEEY [1992-1993] and International Heliophysical Year IHY [2007-2009]. These two projects were mainly focused on the equatorial ionosphere in Africa. In Atmospheric physics our research focused on gravity waves in the framework of the African Multidisciplinary Monsoon Analysis project n°1 [2005-2009 ], on hydrology in the Congo river basin and on lightning in Central Africa, the most lightning part of the world. In Vietnam the study of a broad climate data base highlighted global warming. In space weather, our results essentially concern the impact of solar events on global navigation satellite system GNSS and on the effects of solar events on the circulation of electric currents in the earth (GIC). This research began in the framework of the international space weather initiative project ISWI [2010-2012]. Finally, all these scientific projects have enabled young scientists from the South to publish original results and to obtain positions in their countries. These projects have also crossed disciplinary boundaries and defined a more diversified education which led to the training of specialists in a specific field with knowledge of related scientific fields.

Legal considerations for urban underground space development in Malaysia

2017-12-01

Full Text Available In 2008, the Malaysia land code, named the National Land Code 1965 (NLC 1965, was amended to add Part Five (A to deal with the disposal of underground space. In addition, the Circular of the Director General of Lands and Mines No. 1/2008 was issued to assist the application of Part Five (A of the NLC 1965. However, the legislation is still questionable and has instigated many arguments among numerous actors. Therefore, this research was undertaken to examine legal considerations for the development of underground space. The focus is on four legal considerations, namely underground space ownership, the bundle of rights, depth, and underground space utilization. Rooted in qualitative methods, interviews were conducted with respondents involved in the development of underground space in Malaysia. The obtained data were then analyzed descriptively. The findings differentiated the rights of landowners for surface land and underground space, and their liability for damages and the depth. It was indicated that the current legislation in Malaysia, namely Part Five (A of the NLC 1965 and the Circular of the Director General of Lands and Mines No. 1/2008, is adequate to facilitate the development of underground space in terms of legal considerations. However, to further facilitate the development of underground land in the future, based on the research, four enhancements are recommended for legal considerations pertaining to the development of underground space in Malaysia.

Short-chain chlorinated paraffins (SCCPs) are under review by the Stockholm Convention on Persistent Organic Pollutants. Currently, limited data are available about SCCPs in terrestrial organisms. In the present study, SCCP concentration in the muscles of seven terrestrial bird species (n = 38) inhabiting an e-waste recycling area in South China was determined. This concentration varied from 620 to 17,000 ng/g lipid. Resident birds accumulated significantly higher SCCP concentrations than migratory birds (p < 0.01). Trophic magnification was observed for migratory bird species but not for resident, which was attributed to high heterogeneity of SCCP in e-waste area. Two different homologue group patterns were observed in avian samples. The first pattern was found in five bird species dominated by C 10 and C 11 congeners, while the second was found in the remains, which show rather equal abundance of homologue groups. This may be caused by two sources of SCCPs (local and e-waste) in the study area. - Highlights: • SCCPs in terrestrial bird species from an e-waste area are first reported. • Elevated SCCP level was found as compared with other regions. • Resident birds accumulated significantly higher SCCP levels than migratory birds. • Trophic magnification was observed for migratory but not for resident bird species. • Two homologue patterns were found among seven bird species. - SCCP concentration in terrestrial bird species inhabiting an e-waste site was first reported in this study

Foliar nectar enhances plant-mite mutualisms: the effect of leaf sugar on the control of powdery mildew by domatia-inhabiting mites.

Weber, Marjorie G; Porturas, Laura D; Taylor, Scott A

2016-09-01

Mite domatia are small structures on the underside of plant leaves that provide homes for predacious or fungivorous mites. In turn, mites inhabiting domatia defend the plant by consuming leaf herbivores and pathogens, which can result in a domatia-mediated, plant-mite defence mutualism. Several recent studies have suggested that plants receive enhanced benefits when they provide a foliar food source, such as sugars secreted from extrafloral nectaries, to mite mutualists alongside mite domatia. However, the effect of foliar sugar on reducing leaf pathogen load via domatia-inhabiting mites has not been directly investigated. To fill this gap, the links between foliar sugar addition, domatia-inhabiting mite abundance, and pathogen load were experimentally evaluated in wild grape. Furthermore, because the proposed combined benefits of providing food and housing have been hypothesized to select for the evolutionary correlation of extrafloral nectaries and domatia across plant lineages, a literature survey aimed at determining the overlap of mite domatia and extrafloral nectaries across plant groups was also conducted. It was found that leaves with artificial addition of foliar sugar had 58-80 % more mites than leaves without foliar sugar addition, and that higher mite abundances translated to reduced powdery mildew (Erysiphe necator) loads on leaves. It was found that mite domatia and extrafloral nectaries occur non-randomly in the same clades across Eudicots. Genera with both traits are reported to highlight candidate lineages for future studies. Together, the results demonstrate that foliar sugar can indeed enhance the efficacy of domatia-mediated plant-mite mutualisms, and suggest that this synergism has the potential to influence the co-distribution of foliar nectar and mite domatia across plants. © The Author 2016.

This paper reports on a wide spectrum of oscillations that is excited due to the evolution instabilities, being in a weak above-threshold state, in the inequilibrium media with decaying spectrum. In this case the pumping, whose part is played by an intensive wave or occupation inversion in the active medium, synchronized the phases of excited modes and, thus, forms the space dissipative structure of the field. In dissipative nonlinear media with nondecaying spectrum the space structures, formed due to the development of instability, experience small-scale hexagonal modulation

Distribution function approach to redshift space distortions. Part II: N-body simulations

International Nuclear Information System (INIS)

Okumura, Teppei; Seljak, Uroš; McDonald, Patrick; Desjacques, Vincent

2012-01-01

Measurement of redshift-space distortions (RSD) offers an attractive method to directly probe the cosmic growth history of density perturbations. A distribution function approach where RSD can be written as a sum over density weighted velocity moment correlators has recently been developed. In this paper we use results of N-body simulations to investigate the individual contributions and convergence of this expansion for dark matter. If the series is expanded as a function of powers of μ, cosine of the angle between the Fourier mode and line of sight, then there are a finite number of terms contributing at each order. We present these terms and investigate their contribution to the total as a function of wavevector k. For μ 2 the correlation between density and momentum dominates on large scales. Higher order corrections, which act as a Finger-of-God (FoG) term, contribute 1% at k ∼ 0.015hMpc −1 , 10% at k ∼ 0.05hMpc −1 at z = 0, while for k > 0.15hMpc −1 they dominate and make the total negative. These higher order terms are dominated by density-energy density correlations which contributes negatively to the power, while the contribution from vorticity part of momentum density auto-correlation adds to the total power, but is an order of magnitude lower. For μ 4 term the dominant term on large scales is the scalar part of momentum density auto-correlation, while higher order terms dominate for k > 0.15hMpc −1 . For μ 6 and μ 8 we find it has very little power for k −1 , shooting up by 2–3 orders of magnitude between k −1 and k −1 . We also compare the expansion to the full 2-d P ss (k,μ), as well as to the monopole, quadrupole, and hexadecapole integrals of P ss (k,μ). For these statistics an infinite number of terms contribute and we find that the expansion achieves percent level accuracy for kμ −1 at 6-th order, but breaks down on smaller scales because the series is no longer perturbative. We explore resummation of the terms into Fo

Textile has within the last decade increasingly been regarded as an architectural material. Many new textiles have been developed and this has increased its applications in architecture. But how do textile and space meet and which spatial qualities can arise in this meeting? The paper describes...... a series of practical studies of the spatial qualities that can be established through the design of three very different fabrics. The topic is part of an ongoing Ph.D. project at The Danish Design School in Copenhagen. The main theme of the Ph.D. is the inter-play between textile, space and sound. Space...... and it has a special poetry which is not to be found in any other material. Which spatial qualities can be obtained with these textile properties? Contemporary conception of space in architecture can be said still to rely on the modernist conception. In practical experiments it is investigated how...

Linking the space shuttle and space stations early docking technologies from concept to implementation

Shayler, David J

2017-01-01

How could the newly authorized space shuttle help in the U.S. quest to build a large research station in Earth orbit? As a means of transporting goods, the shuttle could help supply the parts to the station. But how would the two entitles be physically linked? Docking technologies had to constantly evolve as the designs of the early space stations changed. It was hoped the shuttle would make missions to the Russian Salyut and American Skylab stations, but these were postponed until the Mir station became available, while plans for getting a new U. S. space station underway were stalled. In Linking the Space Shuttle and Space Stations, the author delves into the rich history of the Space Shuttle and its connection to these early space stations, culminating in the nine missions to dock the shuttle to Mir. By 1998, after nearly three decades of planning and operations, shuttle missions to Mir had resulted in: • A proven system to link up the space shuttle to a space station • Equipment and hands-on experienc...

Long-term measurements of the radiation exposure of the inhabitants of radioactively contaminated regions of Belarus. The Korma report II (1998-2015)

Radiological long-term measurements were performed between 1998 and 2015 in a region of Belarus that was affected by the Chernobyl accident. The internal radiation exposure of the inhabitants of the village of Volincy (Korma district) - caused by the existing contamination and an increasing lack of precautions in the course of time with regard to eating home-grown food - has experienced a significant decrease from a very high level. External exposure, however, reveals a different picture. Although an overall decrease was observed, the organic constituents of the soil show an increase in contamination. This increase was not observed in soils from cultivated land or gardens. In addition to the measurements, a relationship based on mutual trust allowed us to offer the inhabitants individual advice on how to reduce internal contamination. As a result of this advice and the decreasing environmental contamination (topsoil and crops), the internal dose was reduced significantly. Today, internal exposure is only slightly elevated and has no significant negative influence on the health of the inhabitants. In 2013, the internal dose decreased to less than 0.1 mSv/a. Despite this, the cumulative dose will remain significantly higher than ''normal'' values due to external exposure. Up to now, we have found no statistically significant signs or symptoms of diseases caused by radiation exposure. If internal exposure is checked on a regular basis and individual advice is available, there should be no specific danger for the people in the region in the near future. Resettlement may even be possible in former closed areas provided that people comply with appropriate dietary rules.

Woody plants host diverse communities of associated organisms, including wood-inhabiting fungi. In this group, host effects on species richness and interaction network structure are not well understood, especially not at large geographical scales. We investigated ecological, historical and evolutionary determinants of fungal species richness and network modularity, that is, subcommunity structure, across woody hosts in Denmark, using a citizen science data set comprising > 80 000 records of > 1000 fungal species on 91 genera of woody plants. Fungal species richness was positively related to host size, wood pH, and the number of species in the host genus, with limited influence of host frequency and host history, that is, time since host establishment in the area. Modularity patterns were unaffected by host history, but largely reflected host phylogeny. Notably, fungal communities differed substantially between angiosperm and gymnosperm hosts. Host traits and evolutionary history appear to be more important than host frequency and recent history in structuring interactions between hosts and wood-inhabiting fungi. High wood acidity appears to act as a stress factor reducing fungal species richness, while large host size, providing increased niche diversity, enhances it. In some fungal groups that are known to interact with live host cells in the establishment phase, host selectivity is common, causing a modular community structure. © 2016 The Authors.

Results of long-term radioecological investigations in areas with an enhanced level of natural radioactivity in the north of Russia are summarized. Deleterious changes within animal and plant populations inhabiting areas with an enhanced level of natural radioactivity in the Komi Republic were revealed. These changes are expressed in enhanced levels of mutagenesis, destructive processes in the tissues of animals, disturbances of reproductive functions and reduced offspring viability. Compensatory processes, resulting in animal and plant survival under extremely adverse conditions of radium and uranium-radium contamination, were observed as well. However, obvious signs of adaptation failed to be detected. The findings suggest that adverse somatic and genetic effects are possible in plants and animals in the dose range observed at sites with an enhanced level of natural radioactivity. In contrast, different plant species inhabiting an area with an enhanced level of natural radioactivity in the taiga zone of the Sakha Republic (Yakutia) reveal a stimulation of growth processes, photosynthesis, endogenous low molecular weight antioxidant synthesis as well as adaptive response. It is apparent from the data presented that naturally occurring differences in terrestrial radiation level could be of genetic and ecological consequence.

More and more plastic encapsulated microcircuits (PEMs) are used in space missions to achieve high performance. Since PEMs are designed for use in terrestrial operating conditions, the successful usage of PEMs in space harsh environment is closely related to reliability issues, which should be considered firstly. However, there is no ready-made methodology for PEMs in space applications. This paper discusses the reliability for the usage of PEMs in space. This reliability analysis can be divided into five categories: radiation test, radiation hardness, screening test, reliability calculation and reliability assessment. One case study is also presented to illuminate the details of the process, in which a PEM part is used in a joint space program Double-Star Project between the European Space Agency (ESA) and China. The influence of environmental constrains including radiation, humidity, temperature and mechanics on the PEM part has been considered. Both Double-Star Project satellites are still running well in space now.

Planning countryside space for recreational purposes: The case of the upper water basin of the River Soča

Directory of Open Access Journals (Sweden)

Aleš Golja

2008-01-01

Full Text Available Based on the upper Soča River basin, the article deals with the problem of exploitation of valuable natural features for tourist and recreational purposes. The goal was to propose a model of recreational use of a selected section of the Soča River, to put forward a proposal of legal framework for managing the selected area and work out a management plan for recreational purposes; thus the most burdened area of the Soča River during summer months was chosen, i.e. a 9 km reach of the Soča (between Log Čezsoški and Trnovo ob Soči, and accordingly a feasible marketing proposal, control proposal and spatial planning proposal were given in order to reduce the negative effects on the environment. The chosen methodology combines knowledge and practice from different fields, having in mind that this kind of problem solving should be carried out in an interdisciplinary connection of expert knowledge. Our basic theoretical premise has been environmental protection with an objective to preserve space as a value everywhere and in all its forms. The purpose of environmental protection is to encourage and direct such spatial development that provides a long-term basis for human health, well-being and quality of life as well as maintaining biotic diversity. This enables us to connect space with all its parts and features, sport recreation and tourism, thus achieving quality of life of local inhabitants, well-being of guests, protection of the natural environment, economic development, creation of new work places and income.

The topology of geodesically complete space-times

International Nuclear Information System (INIS)

Lee, C.W.

1983-01-01

Two theorems are given on the topology of geodesically complete space-times which satisfy the energy condition. Firstly, the condition that a compact embedded 3-manifold in space-time be dentless is defined in terms of causal structure. Then it is shown that a dentless 3-manifold must separate space-time, and that it must enclose a compact portion of space-time. Further, it is shown that if the dentless 3-manifold is homeomorphic to S 3 then the part of space-time that it encloses must be simply connected. (author)

The Orbital Space Environment and Space Situational Awareness Domain Ontology - Toward an International Information System for Space Data

Science.gov (United States)

Rovetto, R.

2016-09-01

The orbital space environment is home to natural and artificial satellites, debris, and space weather phenomena. As the population of orbital objects grows so do the potential hazards to astronauts, space infrastructure and spaceflight capability. Orbital debris, in particular, is a universal concern. This and other hazards can be minimized by improving global space situational awareness (SSA). By sharing more data and increasing observational coverage of the space environment we stand to achieve that goal, thereby making spaceflight safer and expanding our knowledge of near-Earth space. To facilitate data-sharing interoperability among distinct orbital debris and space object catalogs, and SSA information systems, I proposed ontology in (Rovetto, 2015) and (Rovetto and Kelso, 2016). I continue this effort toward formal representations and models of the overall domain that may serve to improve peaceful SSA and increase our scientific knowledge. This paper explains the project concept introduced in those publications, summarizing efforts to date as well as the research field of ontology development and engineering. I describe concepts for an ontological framework for the orbital space environment, near-Earth space environment and SSA domain. An ontological framework is conceived as a part of a potential international information system. The purpose of such a system is to consolidate, analyze and reason over various sources and types of orbital and SSA data toward the mutually beneficial goals of safer space navigation and scientific research. Recent internationals findings on the limitations of orbital data, in addition to existing publications on collaborative SSA, demonstrate both the overlap with this project and the need for datasharing and integration.

Results of studies of the influence of reinforcement density and shape of cemented parts on quality of radiological shields are presented. The studies were carried out on built shields and on experimental blocks. The experimental studies were aimed at determination of filling degree under cemented parts of different shapes using two kinds of cement normal and heavy one and at determination of filling degree of space with dense reinforcement as well as space near boarding. The influence of reinforcement density was studied using different spacing between bars and rows of bars. In the case of difficulties with good filling under the cemented parts so called ''beard'' and more liquid mixtures were used with success. (Z.M.)

Full Text Available The Vélib bike rental system is worth analyzing in order to understand how cities move out of a model of large infrastructures towards a personal service principle connected to digital traceability and mapping of all activities. The new offer of bikes distributed all over the city creates a new map for access to mobility resources while introducing citizens to a “personal-public” device. Each feature of the system requires a very well designed information system to match the needs for bikes and to charge the users through cards (credit or transportation cards. Personal data is the essential entity that fuels the whole system and that creates potential privacy problems as well as monetization opportunities. The paper relies on a theoretical framework, called habitele, which accounts for the process of inhabiting that is now extended to the personal data ecosystem. The portability of mobile phones (and other devices such as cards creates an envelope that follows the urban citizen and equips all his activities while it makes a new layer of the city appear, adapted to the personal involvement in the urban environment

Full Text Available Introduction. Population increasingly draws attention to the issues concerning the environment degraded by the progress of civilization and the impact of this process on health. However, public awareness of the risk exposure to indoor contaminants is lagging a long way behind knowledge regarding outdoor environmental hazards. The aim of the study was to assess the risk perception related to exposure to indoor environmental factors in the population of Silesia. Materials and methods. In this study the electronic version of a questionnaire survey – downloaded on the website www.moja-ankiety.pl. was used. During the 3-months duration of the project 552 subjects participated in the survey. In the study participated the Silesian Voivodeship inhabitants such as chat rooms users, newsgroups and online forum participants. Data analysis was performed by using statistical program – STATA Version 8 SE [9], where the Kruskall-Wallis test and χ2 test were applied. Statistical significance was assessed at p value *0.05. Results. Despite the low perception of environmental health hazards inside the dwellings, the majority of respondents were able to indentify health effects and ways to reduce exposure to indoor air pollution. Both gender, place of residence, education level and age significantly affected the level of perception of respondents on the risk connected with exposure to indoor air pollution. Conclusion. It is necessary to continuously work on raising public awareness of environmental health hazards in confined spaces, the causes of their occurrence, types, effects and above all the ways to counter these threats.

We conclude our series of publications on the development of the gradient correlation method (GCM), which can be used for an improved stabilization of the solution space of particle microphysical parameters derived from measurements with multiwavelength Raman and high-spectral-resolution lidar (3 backscatter +2 extinction coefficients). We show results of three cases studies. The data were taken with a ground-based multiwavelength Raman lidar during the Saharan Mineral Dust Experiment in the Cape Verde Islands (North Atlantic). These cases describe mixtures of dust with smoke. For our data analysis we separated the contribution of smoke to the total signal and only used these optical profiles for the test of GCM. The results show a significant stabilization of the solution space of the particle microphysical parameter retrieval on the particle radius domain from 0.03 to 10 μm, the real part of the complex refractive index domain from 1.3 to 1.8, and the imaginary part from 0 to 0.1. This new method will be included in the Tikhonov Advanced Regularization Algorithm, which is a fully automated, unsupervised algorithm that is used for the analysis of data collected with the worldwide first airborne 3 backscatter +2 extinction high-spectral-resolution lidar developed by NASA Langley Research Center.

Self-rated health is a one-point measure commonly used for recognising subjectively perceived health and covering a wide range of individual's health aspects. The aim of our study was to examine the extent to which self-rated health reflects the differences due to demographic characteristics, physical, psychical and social well-being, health disorders, occurrence of chronic disease and negative life events in Polish social and cultural conditions. Data were collected by non-addressed questionnaire methods from 402 Warsaw inhabitants. The questionnaire contained the questions concerning self-rated health, physical, psychical and social well-being, the use of health care services, occurrence of chronic disease and contact with negative life events. The analysis showed that worse self-rated health increased exponentially with age and less sharply with lower level of education. Pensioners were more likely to assess their own health worse then employed or students. Such difference was not found for unemployed. Compared to married, the self-rated health of divorced or widowed respondents was lower. Gender does not differentiate self-rated health. In regard to well-being, self-rated health linearly decreased for physical well-being, for social and, especially, for psychical well-being the differences were significant, but more complicated. Hospitalisation, especially repeated, strongly determined worse self-rated health. In contrast, relationship between self-rated health and sickness absence or frequency of contact with physician were lower. Chronic diseases substantially increased the risk of poorer self-rated health, and their co-morbidity increased the risk exponentially. The patients with cancer were the group, in which the risk several times exceeded that reported for the patients of other diseases. Regarding negative life events, only experience with violence and financial difficulties were resulted in worse self-rated health. Our findings confirmed the usefulness

Botos (Inia geoffrensis) are currently provisioned for use in tourist attractions in five sites in the Brazilian Amazon. Despite the known negative effects associated with human-wild dolphin interactions, this activity has been regulated and licensed in the Anavilhanas National Park in Novo Airão, Amazonas State, Brazil. We present an updated evaluation of the perception of the local community concerning the possible socioeconomic impacts of this tourism in Novo Airão. In April 2011, 45 interviews were conducted with inhabitants. A small segment of Novo Airão perceives currently itself as being economically dependent on the botos feeding tourism. Despite that, the economic benefits of this controversial activity apparently are not shared among most inhabitants, and botos feeding tourism is perceived as generating diverse negative effects. We conclude that if the activity was banned or modified into a less impacting tourist activity, this action would probably not majorly affect the lives of the general population.

Soundscape of Urban Open Spaces in Hong Kong

Lin, Hui

This study aims to investigate the soundscape of urban open spaces in Hong Kong. Open space in densely populated cities has been considered as an important asset for urban inhabitants in that they afford opportunities for leisure, recreation and an active involvement with nature. For quite a long time, visual aesthetic was the dominant consideration in open space design and other senses were given less concern. Continuous stream of attention-demanding sounds from the noisy environment may bombard these open spaces, rendering them no longer able to satisfy the eye alone. Sound and consequently the acoustic environment are receiving increasing attention. This study used noise mapping technique supplemented by GIS spatial analysis tools to delineate quiet open spaces with traffic noise exposure less than 60 dB (A) L10, 1h and conducted field observations to determine their usages. The identified quiet open spaces are either concentrated in hilly and remote areas with low accessibility, or sporadically scattered among tall buildings. Some large urban parks and small sitting-out areas are even located in the center of the city. Larger open spaces serve group visits, such as hiking and sightseeing, while smaller ones are easily accessible to local residents for social and recreational purposes. The acoustic environment III urban open spaces varies with space and time. To characterize the acoustic quality of soundscapes in the quiet open spaces, sound walk and field recording were undertaken place in 25 selected study sites. Despite the dominance of traffic noise, soundscapes in the urban open spaces are also shaped by natural sounds. Sounds from birds and water are common and prevalent particularly in gardens and playgrounds. Soundscape approach is a human-centered point of view. How the visitors perceive and evaluate sounds and the acoustic quality has great implication for soundscape design. On-site interview of 1,610 visitors unravels human preference of individual

Autonomy and the human element in space

Science.gov (United States)

1985-01-01

NASA is contemplating the next logical step in the U.S. space program - the permanent presence of humans in space. As currently envisioned, the initial system, planned for the early 1990's, will consist of manned and unmanned platforms situated primarily in low Earth orbit. The manned component will most likely be inhabited by 6-8 crew members performing a variety of tasks such as materials processing, satellite servicing, and life science experiments. The station thus has utility in scientific and commercial enterprises, in national security, and in the development of advanced space technology. The technical foundations for this next step have been firmly established as a result of unmanned spacecraft missions to other planets, the Apollo program, and Skylab. With the shuttle, NASA inaugurates a new era of frequent flights and more routine space operations supporting a larger variety of missions. A permanently manned space system will enable NASA to expand the scope of its activities still further. Since NASA' s inception there has been an intense debate over the relative merits of manned and unmanned space systems. Despite the generally higher costs associated with manned components, astronauts have accomplished numerous essential, complex tasks in space. The unique human talent to evaluate and respond inventively to unanticipated events has been crucial in many missions, and the presence of crews has helped arouse and sustain public interest in the space program. On the other hand, the hostile orbital environment affects astronaut physiology and productivity, is dangerous, and mandates extensive support systems. Safety and cost factors require the entire station complex, both space and ground components, to be highly automated to free people from mundane operational chores. Recent advances in computer technology, artificial intelligence (AI), and robotics have the potential to greatly extend space station operations, offering lower costs and superior

Velotti, F M; Carlier, E; Goddard, B; Kain, V; Kotzian, G

2017-01-01

Until 2015, the LHC filling schemes used the batch spac-ing as specified in the LHC design report. The maximumnumber of bunches injectable in the LHC directly dependson the batch spacing at injection in the SPS and hence onthe MKP rise time.As part of the LHC Injectors Upgrade project for LHCheavy ions, a reduction of the batch spacing is needed. In thisdirection, studies to approach the MKP design rise time of150ns(2-98%) have been carried out. These measurementsgave clear indications that such optimisation, and beyond,could be done also for higher injection momentum beams,where the additional slower MKP (MKP-L) is needed.After the successful results from 2015 SPS batch spacingoptimisation for the Pb-Pb run [1], the same concept wasthought to be used also for proton beams. In fact, thanksto the SPS transverse feed back, it was already observedthat lower batch spacing than the design one (225ns) couldbe achieved. For the 2016 p-Pb run, a batch spacing of200nsfor the proton beam with100nsbunch spacing wasreque...

1979-01-01

The interaction of magnetized monoenergetic ions (a ring in velocity space) with a homogeneous Maxwellian target plasma is studied numerically using linear Vlasov theory. The ring may be produced when an energetic beam is injected perpendicular to a uniform magnetic field. In addition to yielding the previously known results, the present study classifies this flute-like instability into three distinct regimes based on the beam density relative to the plasma density, where many features such as physical mechanisms, dispersion diagrams, and maximum growth rates are quite different. The effects of electron dynamics, plasma or ring thermal spread, the ratio of ω/sub p//ω/sub c/ for plasma ions, and electromagnetic modifications are also considered

Space Ethics and Protection of the Space Environment

Science.gov (United States)

Williamson, Mark

2002-01-01

The construction of the International Space Station in low Earth orbit and the formulation of plans to search for life on Mars - one day by means of manned missions - indicate that mankind is intent on making the space environment part of its domain. Publicity surrounding space tourism, in-space `burials' and the sale of lunar `real estate' suggests that, some time in the 21st century, the space environment will become an extraterrestrial extension of our current business and domestic environment. This prompts the question of our collective attitude towards the space environment and the degree to which we should regulate its use and protect it for future generations. What, indeed, are the ethical considerations of space exploration and development? Ethics can be defined as "the philosophical study of the moral value of human conduct, and of the rules or principles that ought to govern it". More practically, it represents "an approved code of behaviour" adopted, for example, by a group or profession. If a set of ethics is to be developed for space, it is important that what we refer to as the `space community', or `space profession', is intimately involved. Indeed, if it is not, the profession risks having the job done for it, for example by politicians and members of the general public, who for their own reasons may wish to place restrictions on space development, or ban it altogether. The terrestrial nuclear power industry, for example, has already suffered this fate, while widespread ignorance of the subject has led to a moratorium on the use of RTGs in spacecraft. However, there is a danger in the discussion of ethics that consideration is confined to the philosophical aspects, thus excusing those involved from providing practical solutions to the problems that emerge. The fact that mankind has already affected, and arguably damaged, the space environment transports the discussion beyond the philosophical realm. This paper offers a pragmatic analysis of one

2017-12-01

This paper reviews scientific advances achieved by a North-South network between 2006 and 2016. These scientific advances concern Solar Terrestrial Physics, Atmospheric Physics and Space Weather. In this part A, we introduce knowledge on the Sun-Earth system. We consider the physical process of the dynamo which is present in the Sun, in the core of the Earth and also in the regions between the Sun and the Earth, the solar wind-magnetosphere and the ionosphere. Equations of plasma physics and Maxwell's equations will be recalled. In the Sun-Earth system there are permanent dynamos (Sun, Earth's core, solar wind - magnetosphere, neutral wind - ionosphere) and non-permanent dynamos that are activated during magnetic storms in the magnetosphere and in the ionosphere. All these dynamos have associated electric currents that affect the variations of the Earth's magnetic field which are easily measurable. That is why a part of the tutorial is also devoted to the magnetic indices which are indicators of the electric currents in the Sun-Earth system. In order to understand some results of the part B, we present some characteristics of the Equatorial region and of the electrodynamics coupling the Auroral and Equatorial regions.

Sadono, W.; Herlily

2018-03-01

Inter-group conflict is one of the crucial issues affecting urban development in Northern part of Bekasi. It begins with the destruction of monuments until the rejection of worship places (in this case is a church) by mass organizations. These incidents occurred because the native assumed that the migrants took their territory. They concerned about the modern development brought by the migrants that caused the shrinking of local culture. The behavior of these mass organizations constituted the district that made the urban space seemed ‘not inclusive’ indirectly. This paper offered another alternative in urban design to reduce conflicts within the territory. We sought about the district context and reterritorialized the conflicted area. We used Reterritorialization approach to restore ‘border’ in order to sharpen and strengthen the territory. We conducted direct observation method, socio-cultural mapping, in-depth interview, and 3D model. This paper aimed to affirm the territory in urban space that would be able to accommodate the needs of the district user. The result is a design of transitional space that functionates as negotiation space. The transitional space is an intervention using Reterritorialization approach to reduce conflicts that occur in the urban space of the Northern part of Bekasi.

Production of heterotrophic bacteria inhabiting macroscopic organic aggregates (marine snow) from surface waters

International Nuclear Information System (INIS)

Alldredge, A.L.; Cole, J.J.; Caron, D.A.

1986-01-01

Macroscopic detrital aggregates, known as marine snow, are a ubiquitous and abundant component of the marine pelagic zone. Descriptions of microbial communities occurring at densities 2-5 orders of magnitude higher on these particles than in the surrounding seawater have led to the suggestion that marine snow may be a site of intense heterotrophic activity. The authors tested this hypothesis using incorporation of [ 3 H]thymidine into macromolecules as a measure of bacterial growth occurring on marine snow from oceanic waters in the North Atlantic and from neritic waters off southern California. Abundances of marine snow ranged from 0.1 to 4.3 aggregates per liter. However, only 0.1-4% ration per cell on aggregates was generally equal to or lower than that of bacteria found free-living in the surrounding seawater, indicating that attached bacteria were not growing more rapidly than free-living bacteria. Bacteria inhabiting aggregates were up to 25 times larger than free-living forms

Lessons learned from research and surveillance directed at highly pathogenic influenza A viruses in wild birds inhabiting North America.

2018-05-01

Following detections of highly pathogenic (HP) influenza A viruses (IAVs) in wild birds inhabiting East Asia after the turn of the millennium, the intensity of sampling of wild birds for IAVs increased throughout much of North America. The objectives for many research and surveillance efforts were directed towards detecting Eurasian origin HP IAVs and understanding the potential of such viruses to be maintained and dispersed by wild birds. In this review, we highlight five important lessons learned from research and surveillance directed at HP IAVs in wild birds inhabiting North America: (1) Wild birds may disperse IAVs between North America and adjacent regions via migration, (2) HP IAVs can be introduced to wild birds in North America, (3) HP IAVs may cross the wild bird-poultry interface in North America, (4) The probability of encountering and detecting a specific virus may be low, and (5) Population immunity of wild birds may influence HP IAV outbreaks in North America. We review empirical support derived from research and surveillance efforts for each lesson learned and, furthermore, identify implications for future surveillance efforts, biosecurity, and population health. We conclude our review by identifying five additional areas in which we think future mechanistic research relative to IAVs in wild birds in North America are likely to lead to other important lessons learned in the years ahead.

In this review, we highlight five important lessons learned from research and surveillance directed at HP IAVs in wild birds inhabiting North America: (1) Wild birds may disperse IAVs between North America and adjacent regions via migration, (2) HP IAVs can be introduced to wild birds in North America, (3) HP IAVs may cross the wild bird-poultry interface in North America, (4) The probability of encountering and detecting a specific virus may be low, and (5) Population immunity of wild birds may influence HP IAV outbreaks in North America. We review empirical support derived from research and surveillance efforts for each lesson learned and, furthermore, identify implications for future surveillance efforts, biosecurity, and population health. We conclude our review by identifying five additional areas in which we think future mechanistic research relative to IAVs in wild birds in North America are likely to lead to other important lessons learned in the years ahead.

A data set of myriad and time-varying inhabitant-behavior schedules with a 15 min time resolution, generated by the authors in a previous study, is validated through a comparison analysis. We show three comparisons. The first and second compare the estimated demand with a time series of actual utility demand. The comparisons indicate that the generated data and its algorithm, described by the authors, have an appropriate robustness. Another comparison between the estimate and the annual averaged daily water demand of a residential area, consisting of 9327 residences, also shows an acceptable consistency. (author)

families. In addition, we found that Mapuche people differentiate fish species mainly by morphological, organoleptic and ecological attributes. Current consumption of fish by Mapuche communities is sporadic, in accordance with bibliography and ancient tales. Several fishing tools are used, including modern elements. Our data enable us to characterise dynamic traditional knowledge in these communities, which is flexible in nature and adaptable to new situations, demonstrated by the incorporation not only of new species but also new fishing tools. It also seems that new significances become absorbed in synchrony with the advance or arrival of exotic and invasive species. For the Mapuche, the presence of the white man heralded by exotic trouts speaks of how a recent event, such as the introduction of the salmonids, is already incorporated into Mapuche symbolism. Mapuche traditional knowledge and cosmovision on the use of fish and waters, a vision which promotes respect and the avoidance of actions that could disturb the beings (animals and sacred or mythological characters) that inhabit and take care of them should be fostered as part of management plans of regional natural resources. This paper contributes to the broader literature on freshwater resource management by providing empirical evidence of the critical role of local perceptions in promoting the sustainable management of natural resources.

A Preliminary Study on Connectivity and Perceived Values of Community Green Spaces

Sohyun Park

2017-04-01

Full Text Available Green spaces in residential communities are important yet understudied features of the urban ecological system. While large urban parks and remnant wildlands in urban areas tend to receive public attention from conservation and management perspectives, less is known about the importance of spatial and ecological characteristics of the community-scale green space. This study investigates natural elements in four planned communities in the Phoenix metropolitan area, Arizona; two of which represent conventional types of neighborhoods and two which exemplify community development type with a proclaimed vision of sustainability. These distinct types of communities, which illustrate variations in age, location, open space type, and a cross-section of housing density, are compared with regard to landscape connectivity as a means of gauging the ecological condition for community sustainability. Using Geographical Information Systems and landscape connectivity indices, a community’s green space features were examined including size, physical connectedness, and ecological potential. Furthermore, a questionnaire survey was designed and implemented to examine the perceptional differences between the two types of community residents. The findings demonstrate that the green spaces in conventional communities are more physically connected than their counterparts, but the naturalness and ecological qualities manifested in the amount of the land that may serve as potential urban desert habitats were higher in the sustainable communities. The results of the survey indicated that the respondents inhabiting sustainable communities possess a higher level of satisfaction than the people in conventional types of communities. This is due mainly to the amount of easy access to, and the perceived ecological values of the green spaces in their neighborhoods and surrounding areas. The study concludes that careful community design with ecological consideration can help

Space development and space science together, an historic opportunity

Science.gov (United States)

Metzger, P. T.

2016-11-01

The national space programs have an historic opportunity to help solve the global-scale economic and environmental problems of Earth while becoming more effective at science through the use of space resources. Space programs will be more cost-effective when they work to establish a supply chain in space, mining and manufacturing then replicating the assets of the supply chain so it grows to larger capacity. This has become achievable because of advances in robotics and artificial intelligence. It is roughly estimated that developing a lunar outpost that relies upon and also develops the supply chain will cost about 1/3 or less of the existing annual budgets of the national space programs. It will require a sustained commitment of several decades to complete, during which time science and exploration become increasingly effective. At the end, this space industry will capable of addressing global-scale challenges including limited resources, clean energy, economic development, and preservation of the environment. Other potential solutions, including nuclear fusion and terrestrial renewable energy sources, do not address the root problem of our limited globe and there are real questions whether they will be inadequate or too late. While industry in space likewise cannot provide perfect assurance, it is uniquely able to solve the root problem, and it gives us an important chance that we should grasp. What makes this such an historic opportunity is that the space-based solution is obtainable as a side-benefit of doing space science and exploration within their existing budgets. Thinking pragmatically, it may take some time for policymakers to agree that setting up a complete supply chain is an achievable goal, so this paper describes a strategy of incremental progress. The most crucial part of this strategy is establishing a water economy by mining on the Moon and asteroids to manufacture rocket propellant. Technologies that support a water economy will play an

Scuttle flies (Diptera: Phoridae) are small-sized insects of forensic importance. They are well known for diversified species and habitats, but in the context of forensic entomology, scuttle flies' inhabitance of corpses remains inadequately explored. With recent reports indicating the existence of more scuttle fly species possibly inhabiting these environments, a decomposition study using animal carcasses in enclosed environments was conducted. The aim was to record the occurrence of scuttle flies on rabbit carcasses placed in sealed plastic waste bins for a 40-day period. The study was conducted as two replicates in Bangi, Selangor. Sampling was carried out at different time intervals inside a modified mosquito net as a trap. Inside the trap, adult scuttle flies were aspirated and preserved in 70% ethanol. The fly larvae and pupae were reared until their adult stage to facilitate identification. From this study, six scuttle fly species were collected, i.e., Dahliphora sigmoides (Schmitz) ♂, Gymnoptera simplex (Brues) ♀ , Megaselia scalaris (Loew) ♂♀ , Puliciphora borinquenensis (Wheeler) ♂, Puliciphora obtecta Meijere ♀ and Spiniphora sp. ♀ . Both D. sigmoides and P. obtecta were newly recorded in Malaysia, whilst the Spiniphora sp. was considered an unknown species until it was linked to its male counterpart. The sealed waste bins were found to be accessible for the scuttle flies with delayed arrival (day 4-5). Megaselia scalaris was the primary scuttle fly species attracted to the carcass, and its occurrence could be observed between days 4-7 (replicate 1) and days 5-33 (replicate 2). This study also revealed Sarcophaga spp. (Diptera: Sarcophagidae) as the earliest species to colonize the remains and the longest to inhabit them (days 2-40). The larvae of Hermetia illucens (Linneaus) (Diptera: Stratiomyidae) and Fannia sp . (Diptera: Fanniidae) were found on the carcasses during the mid-advanced decay period. These findings expand the knowledge on

Making Bengali Brick Lane: claiming and contesting space in East London.

Science.gov (United States)

Alexander, Claire

2011-06-01

Based on a recent empirical project on 'the Bengal diaspora', the paper explores the construction and contestation of meanings around the iconic East London street, Brick Lane. Taking the 2006 protests around the film Brick Lane as its starting point, the paper draws on original interviews conducted in 2008 with a range of Bengali community representatives, to examine the narratives of space, community and belonging that emerge around the idea of Brick Lane as the 'cultural heartland' of the British Bangladeshi community. By exploring the representation, production and contestation of 'social space' through everyday practices, the paper engages with and contests the representation of minority ethnic 'communities' in the context of contemporary multicultural London and examines the process of 'claiming' and 'making' space in East London. In so doing, the paper contributes to a critical tradition that challenges essentialising and pathologizing accounts of ethnic communities and racialized spaces, or that places them outside of broader social and historical processes - redolent, for example, in contemporary discussions about 'parallel lives' or 'the clash of civilizations'. By contrast, this paper views social space as made through movement and narration, with a particular emphasis on the social agency of local Bengali inhabitants and the multiple meanings that emerge from within this 'imagined community'. However, rather than simply stressing the unfinished and processual nature of spatial meanings, the paper insists on the historical, embodied and affective dimensions of such meaning making, and a reckoning with the broader social and political landscape within which such meanings take shape. The focus on Brick Lane provides an empirically rich, geographically and historically located lens through which to explore the complex role of ethnicity as a marker of social space and of spatial practices of resistance and identity. By exploring Bengali Brick Lane through

The parapharyngeal space is a fat-filled region situated deep in the head between the basicranium and the oral floor. It can be divided in two parts: the prestyloid and the poststyloid space. The mandibular nerve is contained in the prestyloid space, while the carotid artery, jugular vein, IX, X, XI, XII cranial nerves, cervical sympathetic chain and junctional lymph nodes are situated in the poststyloid compartement. The normal CT anatomy and CT findings in 22 patients with proven lesions of the parapharygeal space are described. Three different groups of neoplastic processes can be distinguished: primary tumours, secondary tumors and enlarged lymph nodes. The nature of the lesions developing in the parapharyngeal space can be diagnosed by CT in many cases

Epithermal neutron activation analysis (ENAA) has been applied to studying elemental composition of Cr(VI)-reducer bacteria isolated from polluted basalts from the Republic of Georgia. Cr(VI)-reducing ability of the bacteria was examined by electron spin resonance (ESR) demonstrating that the bacteria differ in the rates of Cr(VI) reduction. A well-pronounced correlation between the ability of the bacteria to accumulate Cr(VI) and their ability to reduce Cr(V) to Cr(III) observed in our experiments is discussed. Elemental analysis of these bacteria also revealed that basalt-inhabiting bacteria are distinguished by relative contents of essential elements such as K, Na, Mg, Fe, Mn, Zn, and Co. A high rate of Cr(III) formation correlates with a high concentration of Co in the bacterium. ENAA detected some similarity in the elemental composition of the bacteria. The relatively high contents of Fe detected in the bacteria (140-340 μg/g of dry weight) indicate bacterial adaptation to the environmental conditions typical of the basalts. The concentrations of at least 12-19 different elements ranging from major- to ultratrace ones were determined in each type of bacteria simultaneously. The range of concentrations spans over 8 orders of magnitude

The objective of this article is to describe the recent space and furniture utilization study conducted through direct observation at the small, academic-centered Schusterman Library. Student workers from the library's reference desk monitored two semesters of use and went on to observe a third semester after electrical power upgrades were installed. Extensive use details were collected about where library patrons sat during which parts of the day, and certain areas of the library were ultimately identified as much more active than others. Overall, the information gathered proved useful to library planning and will be valuable to future space initiatives. This article further demonstrates feasible means for any library to implement a similar study with minimal resources.

Radiation dosimetry onboard the International Space Station ISS

International Nuclear Information System (INIS)

Berger, Thomas

2008-01-01

Besides the effects of the microgravity environment, and the psychological and psychosocial problems encountered in confined spaces, radiation is the main health detriment for long duration human space missions. The radiation environment encountered in space differs in nature front that on earth, consisting mostly of high energetic ions from protons up to iron, resulting in radiation levels far exceeding the ones encountered on earth for occupational radiation workers. Therefore the determination and the control of the radiation load on astronauts is a moral obligation of the space faring nations. The requirements for radiation detectors in space are very different to that on earth. Limitations in mass, power consumption and the complex nature of the space radiation environment define and limit the overall construction of radiation detectors. Radiation dosimetry onboard the International Space Station (ISS) is accomplished to one part as ''operational'' dosimetry aiming for area monitoring of the radiation environment as well as astronaut surveillance. Another part focuses on ''scientific'' dosimetry aiming for a better understanding of the radiation environment and its constitutes. Various research activities for a more detailed quantification of the radiation environment as well as its distribution in and outside the space station have been accomplished in the last years onboard the ISS. The paper will focus on the current radiation detectors onboard the ISS, their results, as well as on future planned activities. (orig.)

The quality of the air is studied in inhabited areas located near from a petroleum perforation and extraction company. Three halfway points of the areas of more racking and of treatment of product were selected and it was determined the day variation of the levels of concentration of SO2 and SH2 with a frequency of sampling of every 6 hours. By means of the statistical analysis it concludes that the ambient air in the valued points receives a severe contamination with directions of East component wind and variable speed, and the potential sources of emissions that influence on each point settle down. It is recommended to improve the hermetic in the storage and pumping of crude oil systems in the central battery of the company to minimize the fugitive emissions of SH2

Objective of this work is revealing of main dose"forming factors of internal doses for inhabitants of contaminated regions of Kyiv region relying on the results of integral dosimetric monitoring. Three villages have been chosen for the investigation. They are: Raghivka, Zelena Poliana (Poliske district), Karpylivka (Ivankiv district). Twice a year, in May and in October those villages' residents were inspected for content of incorporated "1"3"7Cs. They were measured by direct method at the place of residence with the help of whole body counters (WBC). The principal food samples were collected for detection of "9"0Sr and "1"3"7Cs content. Those villages' inhabitants were interviewed about food consumption levels. Mathematical, dosimetric and radio-chemical methods were used in this work. The estimation of internal doses due to intake of "1"3"7Cs by ingestion of milk and potatoes are in the range 0.3-34% of doses estimated on the base of WBC data. The contribution to the dose of internal exposure from intake of "1"3"7Cs with the milk consumption is no more than two times higher than the contribution of potatoes consumption in the case of equal consumption levels of these products. Contributions to the dose of internal exposure from intake of "9"0Sr with milk and potatoes consumptions are approximately similar. Consumption of mushrooms and other wild nature products by inhabitants from the inspected settlements is the main forming factor of internal dose due to "1"3"7Cs intake

The objective of this paper is the design of computer supported joint action spaces. It is argued against a view of functionality as residing in computer applications. In such a view the creation of functionality is equivalent to the creation of computer applications. Functionality, in the view...... advocated in this paper, emerges in the specific dynamic interplay of actors, objectives, structures, practices and means. In this view, functionality is the result of creating, harnessing and inhabiting computer supported joint action spaces. The successful creation and further development of a computer...... supported joint action space comprises a whole range of appropriate design contributions. The approach is illustrated by the example of the creation of the computer supported joint action space "exchange network of voluntary union educators". As part of the effort a group of participants created...

The Mini Space Farm—A Food Regenerative System in the Long-term Manned Space Mission.

Zhang, Mao

In this invention we propose rearing six types of small animals which are mainly insects, all the biological wastes (bio-waste) in the space human life environment, including the human and animal feces, inedible parts of the plants and animals, food bits and other bio-wastes,can be feedstuff for rearing these six small animals, each one can recycle and digest the specific wastes to be their nourishing biomass. The biomass of these six animals, combine with the inedible parts of the space plants, will further be used as feedstuff for feeding edible animals of poultry, aquatics, amphibians, even the livestock. The meat, egg and milk from these edible animals are taken as human's animal food. Here we name these animals are as Edible Animal (EA), these six small animals are as Recycling Animals (RA). The water and nutrition left in the residues after rearing the RA can be recycled again by other RA or used to fertilize the space plants. The appropriate space plants include both terrestrial and aquatic species, such as vegetable,grain,feeding plant,edible algae and germs,also be cultivated as vegetarian food which have already successfully developed by NASA and other countries. These RA have strong reproduction ability, short life cycle, rich of nutrition, and can be easily reared in high densities with high efficiency in microgravity. Like the RA, the EA and space plants, they can be continuously reared in cages,boxes and water tanks as the solid manner, their optimal growth temperature and the humidity are same with RA, so they can be fed in the same cabin. Rearing RA, EA and plants together can provide a self-sustaining food system with minimum volume, weight, energy, labor and cost, which is the basis for realizing mini space farm in long term manned space missions. In this way, two kinds of mini space farm models have been designed: A cabin model to be used on ISS and flight craft functioning within a microgravity environment, and a greenhouse model to be used on

With respect to the radiation risk assessment, it is important to estimate the accurate doses of inhabitants, due to protracted exposure after the Chernobyl accident as well as the high doses just after the accident. We used a model for estimation of the dose with a long-term temporal change using information of dose rate on the ground and profile of the activity depth distribution in soil. A value C t [μSv h -1 /(MBq m -2 )], which is dose rate in air corresponding to the initial deposition of 137 Cs on the ground just after the accident, was analyzed using the results of the measurements of dose rate in air and activity in soil samples in the contaminated area of Bryansk region in Russia. From the analysis, the value, C 12 at 12 years after the accident can be predicted by categorizing usage of the land. The values obtained from the results of the actual measurement were 1.5 for forest, 1.0 for pasture, 0.6 for yard, and 0.45 for arable or kitchen garden. Temporal change of C t was estimated with a vertical migration model of activity in soil developed by Golikov et al. Annual dose due to 137 Cs and 134 Cs contamination in the period from 1987 to 1999 in farmers, and forest workers were estimated by the model using above values. The results were in good agreement with those obtained by using the personal dose monitoring. The cumulative doses of the inhabitants estimated by the model range from 10 to 60 mSv. (author)

Adriaensen, Maarten; Giannopapa, Christina; Sagath, Daniel; Papastefanou, Anastasia

2015-12-01

The European Space Agency (ESA) has twenty Member States with a variety of strategic priorities and governance structures regarding their space activities. A number of countries engage in space activities exclusively though ESA, while others have also their own national space programme. Some consider ESA as their prime space agency and others have additionally their own national agency with respective programmes. The main objective of this paper is to provide an up-to date overview and a holistic assessment of strategic priorities and the national space governance structures in 20 ESA Member States. This analysis and assessment has been conducted by analysing the Member States public documents, information provided at ESA workshop on this topic and though unstructured interviews. The paper is structured to include two main elements: priorities and trends in national space strategies and space governance in ESA Member States. The first part of this paper focuses on the content and analysis of the national space strategies and indicates the main priorities and trends in Member States. The priorities are categorised with regards to technology domains, the role of space in the areas of sustainability and the motivators that boost engagement in space. These vary from one Member State to another and include with different levels of engagement in technology domains amongst others: science and exploration, navigation, Earth observation, human space flight, launchers, telecommunications, and integrated applications. Member States allocate a different role of space as enabling tool adding to the advancement of sustainability areas including: security, resources, environment and climate change, transport and communication, energy, and knowledge and education. The motivators motivating reasoning which enhances or hinders space engagement also differs. The motivators identified are industrial competitiveness, job creation, technology development and transfer, social benefits

Optimization of coastal protection measures on small islands in the northfrisian part of the North Sea

Wöffler, T.; Jensen, J.; Schüttrumpf, H.

2017-12-01

Low lying small islands are among the most vulnerable regions worldwide due to the consequences of climate change. The reasons for this are the concentration of infrastructure, geographical features and their small size. Worldwide special forms and adaptations of coastal protection strategies and measures can be found on small islands. In the northfrisian part of the North Sea worldwide unique strategies and measures have been developed in the last centuries due to the geographic location and the isolation during extreme events. One special feature of their coastal protection strategy is the lack of dikes. For this reason, the houses are built on artificial dwelling mounds in order to protect the inhabitants and their goods against frequently occurring inundations during storm surge seasons (up to 30 times a year). The Hallig islands themselves benefit by these inundations due to sediments, which are accumulated on the island's surfaces. This sedimentation has enabled a natural adaption to sea level rise in the past. Nevertheless, the construction methods of the coastal protection measures are mainly based on tradition and the knowledge of the inhabitants. No resilient design approaches and safety standards for these special structures like dwelling mounds and elevated revetments exist today. For this reason, neither a cost efficient construction nor a prioritization of measures is possible. Main part of this paper is the scientific investigation of the existing coastal protection measures with the objective of the development of design approaches and safety standards. The results will optimize the construction of the existing coastal protection measures and can be transferred to other small islands and low lying areas worldwide.

Commercial Space Travel, Ethics and Society

Cox, N. L. J.

2002-01-01

For the past two decades interest in the possibilities of commercial (manned) space travel or space tourism has increased among engineers, scientists, entrepreneurs and also citizens. A continuously growing collection of papers is being published on space tourism itself and associated subjects, like new reusable launch vehicles, space habitats, space entertainment and corresponding law and regulation. Market research promises sufficient interest in tourist space travel to take off and develop into a multi billion-dollar business. The basic engineering knowledge and expertise is available to start development and designing of safe and affordable reusable vertical lift off and landing vehicles, like the Kankoh-Maru. However, many issues remain fairly untouched in literature. These include, for example, regulations, law, international agreement on space traffic control and also insurance policy. One important topic however has been barely touched upon. This concerns the ethical issues in commercial (manned) space travel, which need to be considered thoroughly, preferably before actual take off of the first regular space tourist services. The answer to the latter question comprises the major part of the paper. First, the paper deals with the issue of who wants, needs and will go to space at what stage in the development of the space tourism industry. A schematic pyramid differentiating between several community groups is made. Secondly, it discusses the way we can and should deal with our environment. Space is still fairly unspoiled, although there is a lot of (government) debris out there. Rules of the space tourist game need to be established. A few general directions are presented, for example on debris cleaning and garbage disposal. Also our right to exploit the asteroids and the moon for material is discussed. In the last part of this paper, the risks involved with the harsh environment of space are considered. Is it safe and responsible to eject people into outer

A Strategy for Thailand's Space Technology Development: National Space Program (NSP)

Science.gov (United States)

Pimnoo, Ammarin; Purivigraipong, Somphop

2016-07-01

The Royal Thai Government has established the National Space Policy Committee (NSPC) with mandates for setting policy and strategy. The NSPC is considering plans and budget allocation for Thai space development. NSPC's goal is to promote the utilization of space technology in a manner that is congruent with the current situation and useful for the economy, society, science, technology, educational development and national security. The first proposed initiative of the National Space Program (NSP) is co-development of THEOS-2, a next-generation satellite system that includes Thailand's second and third earth observation satellite (THAICHOTE-2 and THAICHOTE-3). THEOS-1 or THAICHOTE-1 was the first Earth Observation Satellite of Thailand launched in 2008. At present, the THAICHOTE-1 is over the lifetime, therefore the THEOS-2 project has been established. THEOS-2 is a complete Earth Observation System comprising THAICHOTE-2&3 as well as ground control segment and capacity building. Thus, NSPC has considered that Thailand should manage the space system. Geo-Informatics and Space Technology Development Agency (GISTDA) has been assigned to propose the initiative National Space Program (NSP). This paper describes the strategy of Thailand's National Space Program (NSP) which will be driven by GISTDA. First, NSP focuses on different aspects of the utilization of space on the basis of technology, innovation, knowledge and manpower. It contains driving mechanisms related to policy, implementation and use in order to promote further development. The Program aims to increase economic competitiveness, reduce social disparity, and improve social security, natural resource management and environmental sustainability. The NSP conceptual framework includes five aspects: communications satellites, earth observation satellite systems, space economy, space exploration and research, and NSP administration. THEOS-2 is considered a part of NSP with relevance to the earth observation

Peripersonal space in the brain.

di Pellegrino, Giuseppe; Làdavas, Elisabetta

2015-01-01

Research in neuroscience reveals that the brain constructs multiple representation of space. Here, we primarily focus on peripersonal space (PPS) representation, the region of space immediately surrounding our bodies and in which objects can be grasped and manipulated. We review convergent results from several generations of studies, including neurophysiological studies in animals, neuropsychological investigations in monkeys and brain-damaged patients with spatial cognition disorders, as well as recent neuroimaging experiments in neurologically normal individuals. Collectively, these studies show that the primate brain constructs multiple, rapidly modifiable representations of space, centered on different body parts (i.e., hand-centered, head-centered, and trunk-centered), which arise through extensive multisensory interactions within a set of interconnected parietal and frontal regions. PPS representations are pivotal in the sensory guidance of motor behavior, allowing us to interact with objects and, as demonstrated by recent studies, with other people in the space around us.

Prisniakov, V.; Prisniakova, L.

The success in deployment of the space programs now in many respects depends on comprehension by the citizens of necessity of programs, from "space" erudition of country. Purposefulness and efficiency of the "space" teaching and educational activity depend on knowledge of relationships between separate variables of such process. The empirical methods of ``space'' well-information of the taxpayers should be supplemented by theoretical models permitting to demonstrate a ways of control by these processes. Authors on the basis of their experience of educational activity during 50- years of among the students of space-rocket profession obtain an equation of ``space" state of the society determining a degree of its knowledge about Space, about achievements in its development, about indispensable lines of investigations, rates of informatization of the population. It is supposed, that the change of the space information consists of two parts: (1) - from going of the information about practical achievements, about development special knowledge requiring of independent financing, and (2) from intensity of dissemination of the ``free" information of a general educational line going to the population through mass-media, book, in family, in educational institutions, as a part of obligatory knowledge of any man, etc. In proposed model the level space well-information of the population depends on intensity of dissemination in the society of the space information, and also from a volume of financing of space-rocket technology, from a part of population of the employment in the space-rocket programs, from a factor of education of the population in adherence to space problems, from welfare and mentality of the people, from a rate of unemployment and material inequality. Obtained in the report on these principles the equation of a space state of the society corresponds to catastrophe such as cusp, the analysis has shown which one ways of control of the public understanding of space

Direct and Indirect Information in Urban Space Planning

Alessandro Bove

2013-06-01

Full Text Available The relationship between new technologies and urban space has become, especially with the introduction of the concept of smart city, the key in the definition of management options in the city itself.The opportunities provided by the use of new technologies to manage the complexity of multiple aspects on the relationship between city and people can address strategies and innovation in order to improve the quality of life of the inhabitants. In smart cities different groups of people with different instances can be directly involved in the transformation process and the planners’ choices can be supported by information that once would have required costly research. This possibility is granted by the availability of great quantities of data that can be collected and analyzed. Direct information can be gathered by multiple sensors (accelerometer, a geomagnetic sensor, and proximity sensor, etc. that offer an immediate evaluation of a specific phenomenon. At the same time other aspects can be evaluated by information obtained in social networks: these can contribute to the definition of urban design as the result of a multi criteria analyses. The way to achieve these strategies is a process of interaction between spatial reality and perceived reality made available by passive forms of participation that can help planners in understanding territorial actors’ / territorial users’ needs and requirements.Through this approach, the design and decisions about urban space are not to be indifferent to the needs expressed by various categories of population.

Radiation dosimetry onboard the International Space Station ISS

Energy Technology Data Exchange (ETDEWEB)

Berger, Thomas [German Aerospace Center - DLR, Inst. of Aerospace Medicine, Radiation Biology, Cologne (Germany)

2008-07-01

Besides the effects of the microgravity environment, and the psychological and psychosocial problems encountered in confined spaces, radiation is the main health detriment for long duration human space missions. The radiation environment encountered in space differs in nature front that on earth, consisting mostly of high energetic ions from protons up to iron, resulting in radiation levels far exceeding the ones encountered on earth for occupational radiation workers. Therefore the determination and the control of the radiation load on astronauts is a moral obligation of the space faring nations. The requirements for radiation detectors in space are very different to that on earth. Limitations in mass, power consumption and the complex nature of the space radiation environment define and limit the overall construction of radiation detectors. Radiation dosimetry onboard the International Space Station (ISS) is accomplished to one part as 'operational' dosimetry aiming for area monitoring of the radiation environment as well as astronaut surveillance. Another part focuses on 'scientific' dosimetry aiming for a better understanding of the radiation environment and its constitutes. Various research activities for a more detailed quantification of the radiation environment as well as its distribution in and outside the space station have been accomplished in the last years onboard the ISS. The paper will focus on the current radiation detectors onboard the ISS, their results, as well as on future planned activities. (orig.)

Full Text Available Supercapacitors offer a wide range of applications for space flight. The aim of this activity was to pursue life tests on commercial off the shelf (COTS supercapacitors from different manufacturers, to evaluate their performance after long term vacuum exposure and to investigate balancing designs for the use of these cells in banks of supercapacitors (BOSC. This study enabled to select the most suitable part for space applications and to confirm the design rules at unit level and deratings at component level, which need to be applied. All those complementary results have paved the way to the on-going activities related to Nesscap 10F qualification and associated modular Bank Of Supercapacitors development for space applications.

WHAT MOTIVATES CULTURAL TOURISTS? AN ANALYSIS OF BUCHAREST INHABITANTS' MOTIVATION TO VISIT THE CENTRE REGION

Directory of Open Access Journals (Sweden)

Ravar Anamaria Sidonia

2013-07-01

Full Text Available Cultural tourism is currently one of the main driving forces of the tourist phenomena, accounting for a significant part of the world's tourist flows. Cultural tourism may take many forms, according to the motivation behind tourists' impetus to travel to a certain destination. Cultural heritage and historical sites, dance, music and theatre performances, art galleries, museums and exhibitions, religious and worship sites and ethnic traditions are the main attractions for tourists motivated by knowledge seeking, self-development and the desire to experience other cultures. Although cultural motivations play an important role in the generation of tourist flows towards cultural tourism destinations, a tourism experience is rarely generated as a result of a single motivation. The act of choosing a specific destination and tourism product is influenced by multiple motivations, not only cultural but also connected to relaxation or family. Furthermore, tourism products are rarely homogeneous – a single holiday may include experiences with cultural content as well as leisure time, sports, adventure or entertainment. Thus, culture is not always the main motivation behind cultural tourism and may in fact be less central to the decision to travel than other factors. This is particularly true in the case of destinations which dispose of various cultural assets, but whose natural tourist resources – such as landscape, climate, access to the sea – also makes them attractive for other types of tourism. The aim of this article is to show that in the case of tourist destinations where cultural attractions represent the vast majority of the areas' tourist heritage, cultural motivations remains central to the decision to travel. Furthermore, we will seek to identify the main types of cultural attractions that motivate cultural tourism in Romania by investigating Bucharest inhabitants' perception of the Centre Region, a cultural destination par excellence in

Winnicott and Arendt: bridging potential and political spaces.

LaMothe, Ryan

2014-04-01

In this article, the author seeks to bridge analytic theory, which is used as an interpretive framework to understand patients' psychic lives, and political philosophy, which accounts for individuals living a life in common as citizens. Specifically, I address how we can understand the relation between the psychosocial space of a parent(s) and child interaction, which becomes part of the child's psychic life, and the political space between and within citizens. The underlying claim is that there is a correlation between political space and the space between parent and child. I use an emended version of Donald Winnicott's concept of potential space and political philosopher Hannah Arendt's notion of the space of appearances to suggest connections between the consulting room and political space.

Impact of the AD 79 explosive eruption on Pompeii, II. Causes of death of the inhabitants inferred by stratigraphic analysis and areal distribution of the human casualties

Luongo, Giuseppe; Perrotta, Annamaria; Scarpati, Claudio; De Carolis, Ernesto; Patricelli, Giovanni; Ciarallo, Annamaria

2003-08-01

Detailed descriptions of the effects of explosive eruptions on urban settlements available to volcanologists are relatively rare. Apart from disease and starvation, the largest number of human deaths caused by explosive eruptions in the twentieth century are due to pyroclastic flows. The relationship between the number of victims related to a specific hazard and the presence of urban settlements in the area covered by the eruption has been shown. However, pyroclastic falls are also extremely dangerous under certain conditions. These conclusions are based on archaeological and volcanological studies carried out on the victims of the well-known AD 79 eruption of Vesuvius that destroyed and buried the Roman city of Pompeii. The stratigraphic level in the pyroclastic deposit and the location of all the casualties found are described and discussed. The total number of victims recovered during the archaeological excavations amounts to 1150. Of these, 1044 well recognisable bodies plus an additional group of 100 individuals were identified based on the analysis of several groups of scattered bones. Of the former, 394 were found in the lower pumice lapilli fall deposit and 650 in the upper stratified ash and pumice lapilli pyroclastic density currents (PDCs) deposits. In addition, a tentative evaluation suggests that 464 corpses may still be buried in the unexcavated part of the city. According to the reconstruction presented in this paper, during the first phase of the eruption (August 24, AD 79) a huge quantity of pumice lapilli fell on Pompeii burying the city under 3 m of pyroclastic material. During this eruptive phase, most of the inhabitants managed to leave the city. However, 38% of the known victims were killed during this phase mainly as a consequence of roofs and walls collapsing under the increasing weight of the pumice lapilli deposit. During the second phase of the eruption (August 25, AD 79) 49% of the total victims were on the roadways and 51% inside

Life Support for Deep Space and Mars

Science.gov (United States)

Jones, Harry W.; Hodgson, Edward W.; Kliss, Mark H.

2014-01-01

How should life support for deep space be developed? The International Space Station (ISS) life support system is the operational result of many decades of research and development. Long duration deep space missions such as Mars have been expected to use matured and upgraded versions of ISS life support. Deep space life support must use the knowledge base incorporated in ISS but it must also meet much more difficult requirements. The primary new requirement is that life support in deep space must be considerably more reliable than on ISS or anywhere in the Earth-Moon system, where emergency resupply and a quick return are possible. Due to the great distance from Earth and the long duration of deep space missions, if life support systems fail, the traditional approaches for emergency supply of oxygen and water, emergency supply of parts, and crew return to Earth or escape to a safe haven are likely infeasible. The Orbital Replacement Unit (ORU) maintenance approach used by ISS is unsuitable for deep space with ORU's as large and complex as those originally provided in ISS designs because it minimizes opportunities for commonality of spares, requires replacement of many functional parts with each failure, and results in substantial launch mass and volume penalties. It has become impractical even for ISS after the shuttle era, resulting in the need for ad hoc repair activity at lower assembly levels with consequent crew time penalties and extended repair timelines. Less complex, more robust technical approaches may be needed to meet the difficult deep space requirements for reliability, maintainability, and reparability. Developing an entirely new life support system would neglect what has been achieved. The suggested approach is use the ISS life support technologies as a platform to build on and to continue to improve ISS subsystems while also developing new subsystems where needed to meet deep space requirements.

The coadjoint orbit spaces of Diff(S1) and Teichmueller spaces

International Nuclear Information System (INIS)

Nag, S.; Verjovsky, A.

1989-09-01

Precisely two of the homogeneous spaces that appear as coadjoint orbits of the group of string reparametrizations (Diff (S 1 )) carry in a natural way the structure of infinite dimensional, holomorphically homogeneous complex analytic Kaehler manifolds. These are N = Diff (S 1 )/Rot (S 1 ) and M = Diff (S 1 )/Moeb (S 1 ). Note that N is a holomorphic disc fiber space over M. Now, M can be naturally considered as embedded in the classical universal Teichmueller space T(1), simply by noting that a diffeomorphism of S 1 is a quasisymmetric homeomorphism. T(1) is itself a homomorphically homogeneous complex Banach manifold. We prove in the first part of the paper that the inclusion of M in T(1) is complex analytic. In the latter portion of this paper it is shown that the unique homogeneous Kaehler metric carried by M = Diff (S 1 )/SL(2, R) induces precisely the Weil-Petersson metric on the Teichmueller space. This is via our identification of M as a holomorphic submanifold of universal Teichmueller space. Now recall that every Teichmueller space T(G) of finite or infinite dimension is contained canonically and holomorphically within T(1). Our computations allow us also to prove that every T(G), G any infinite Fuchsian group, projects out of M transversely. This last assertion is related to the ''fractal'' nature of G-invariant quasicircles, and to Mostow rigidity on the line. Our results thus connect the loop space approach to bosonic string theory with the sumover moduli (Polyakov path integral) approach. (author). 21 refs

Luo, F J; Luo, Z D; Ma, L

1995-10-01

Since 1991, it has been repeatedly reported that endemic arsenism was noticed in the large areas in the middle and west parts of Inne Mongolian Autonomous Region. Heihe village is located in a geological area with rich natural arsenic. The inhabitants of the village have drunk the water with high arsenic content for a long time and many people have died of malignant tumours. A historical prospective method has been used in the study. The research has been carried out chronologically on the statistical relationship between drinking water with high arsenic content consumed by local inhabitants for 22 years and the mortality of malignant tumours. This study has confirmed that the accumulated mortality rate and the average mortality rate of Heihe villagers who had drunk the water with high arsenic content for a number of total 22 years (from January 1971 to January 1993) were 13 590/10(5) person-year and 642.01/10(5) person-year. In terms of the portion among all malignant tumour deaths, cancer for the lung takes the lead, followed by liver cancer and then bladder cancer. The risk of death of malignant tumours in the villagers who drink water with high arsenic content was 9.38 times to the risk in the inhabitants who do not drink water with high arsenic content.

PREREM is intended to provide easy access to current and self-consistent nuclear decay and radionuclide-specific metabolic data sets. Provision is made for revision of metabolic data, and the code is intended for both production and research applications. Documentation for the code is in two parts. Part I is a user's manual which emphasizes interpretation of program prompts and choice of user input. Part II stresses internal structure and flow of program control and is intended to assist the researcher who wishes to revise or modify the code or add to its capabilities. PREREM is written for execution on a Digital Equipment Corporation PDP-10 System and much of the code will require revision before it can be run on other machines. The source program length is 950 lines (116 blocks) and computer core required for execution is 212 K bytes. The user must also have sufficient file space for metabolic and S-factor data sets. Further, 64 100 K byte blocks of computer storage space are required for the nuclear decay data file. Computer storage space must also be available for any output files produced during the PREREM execution. 9 refs., 8 tabs.

Fixed point theory in metric type spaces

CERN Document Server

Agarwal, Ravi P; O’Regan, Donal; Roldán-López-de-Hierro, Antonio Francisco

2015-01-01

Written by a team of leading experts in the field, this volume presents a self-contained account of the theory, techniques and results in metric type spaces (in particular in G-metric spaces); that is, the text approaches this important area of fixed point analysis beginning from the basic ideas of metric space topology. The text is structured so that it leads the reader from preliminaries and historical notes on metric spaces (in particular G-metric spaces) and on mappings, to Banach type contraction theorems in metric type spaces, fixed point theory in partially ordered G-metric spaces, fixed point theory for expansive mappings in metric type spaces, generalizations, present results and techniques in a very general abstract setting and framework. Fixed point theory is one of the major research areas in nonlinear analysis. This is partly due to the fact that in many real world problems fixed point theory is the basic mathematical tool used to establish the existence of solutions to problems which arise natur...

Commercial Parts Technology Qualification Processes

Science.gov (United States)

Cooper, Mark S.

2013-01-01

Many high-reliability systems, including space systems, use selected commercial parts (including Plastic Encapsulated Microelectronics or PEMs) for unique functionality, small size, low weight, high mechanical shock resistance, and other factors. Predominantly this usage is subjected to certain 100% tests (typically called screens) and certain destructive tests usually (but not always) performed on the flight lot (typically called qualification tests). Frequently used approaches include those documented in EEE-INST-002 and JPL DocID62212 (which are sometimes modified by the particular aerospace space systems manufacturer). In this study, approaches from these documents and several space systems manufacturers are compared to approaches from a launch systems manufacturer (SpaceX), an implantable medical electronics manufacturer (Medtronics), and a high-reliability transport system process (automotive systems). In the conclusions section, these processes are outlined for all of these cases and presented in tabular form. Then some simple comparisons are made. In this introduction section, the PEM technology qualification process is described, as documented in EEE-INST-002 (written by the Goddard Space Flight Center, GSFC), as well as the somewhat modified approach employed at the Jet Propulsion Laboratory (JPL). Approaches used at several major NASA contractors are also described

2004 Space Report: Environment and Strategy for Space Research at NATO's Research and Technology Organisation (RTO)

Woods-Vedeler, Jessica A.

2007-01-01

This report describes the motivation for and a strategy to enhance the NATO Research and Technology Organisation's (RTO) current space research effort to reflect NATO's growing military dependence on space systems. Such systems and services provided by these systems are critical elements of military operations. NATO uses space systems for operational planning and support, communication, radio navigation, multi-sensor and multi-domain demonstrations. Such systems are also used to promote regional stability. A quantitative analysis of work related to space in the NATO RTO showed that during the period of 1998 - 2004, 5% of the research pursued in the NATO RTO has been clearly focused on space applications. Challenging environmental and organizational barriers for increasing RTO space research were identified. In part, these include lack of sufficient space expertise representation on panels, the military sensitivity of space, current panel work loads and the need for specific technical recommendations from peers. A strategy for enhancing space research in the RTO is to create a limited-life Space Advisory Group (SAG) composed of Space Expert Consultants who are panel members with appropriate expertise and additional expertise from the nations. The SAG will recommend and find support in the nations for specific technical activities related to space in the areas of Space Science, Remote Sensing Data Analysis, Spacecraft Systems, Surveillance and Early Warning, Training and Simulation and Policy. An RTO Space Advisory Group will provide an organizational mechanism to gain recognition of RTO as a forum for trans-Atlantic defence space research and to enhance space research activities.

AM is a technology of choice for manufacturing of parts with complex shapes (heat exchangers, RF supports, optical parts…) and integrated functions such as conformal cooling channels, clips, hinges, etc. This opens the door for lightweight parts which are of prime importance for space applications. The potential of the AM technologies is however impeded by the quite rough surface finish that is observed on the as-m...

Biopan-survival I: exposure of the osmophiles synechococcus sp. (Nageli) and haloarcula sp. to the space environment

Science.gov (United States)

Mancinelli, R. L.; White, M. R.; Rothschild, L. J.

The objective of this study was to determine the survivability of osmophilic microorganisms in space, as well as examine the DNA breakage in osmophilic cells exposed to solar UV-radiation plus vacuum and to vacuum only. The organisms used were an unidentified species of Synechococcus (Nägeli) that inhabits the evaporitic gypsum-halite crusts that form along the marine intertidal, and an unidentified species of the extremely halophilic genus Haloarcula (designated as isolate G) isolated from a evaporitic NaCl crystal. Because these organisms are desiccation resistant and gypsum-halite as well as NaCl attenuate UV-radiation, we hypothesized that these organisms would survive in the space environment, better than most others. The organisms were exposed to the space environment for 2 weeks while in earth orbit aboard the Biopan facility. Ground controls were tested in a space simulation facility. All samples were compared to unexposed samples. Survivability was determined by plate counts and the most probable number technique. DNA breakage was determined by labeling breaks in the DNA with ^32P followed by translation. Results indicate that the osmophilic microbes survived the 2 week exposure. The major cause of cell death was DNA damage. The number of strand breaks in the DNA from vacuum UV exposed cells was greater than the vacuum only exposed cells.

The twenty-first century in space

Evans, Ben

2015-01-01

This final entry in the History of Human Space Exploration mini-series by Ben Evans continues with an in-depth look at the latter part of the 20th century and the start of the new millennium. Picking up where Partnership in Space left off, the story commemorating the evolution of manned space exploration unfolds in further detail. More than fifty years after Yuri Gagarin’s pioneering journey into space, Evans extends his overview of how that momentous voyage continued through the decades which followed. The Twenty-first Century in Space, the sixth book in the series, explores how the fledgling partnership between the United States and Russia in the 1990s gradually bore fruit and laid the groundwork for today’s International Space Station. The narrative follows the convergence of the Shuttle and Mir programs, together with standalone missions, including servicing the Hubble Space Telescope, many of whose technical and human lessons enabled the first efforts to build the ISS in orbit. The book also looks to...

Ethnomedicinal knowledge of the Indian Himalayas is very interesting because of the wide range of medicinal plants used in traditional medical practice. However, there is a danger of knowledge being lost because the knowledge sharing is very limited and passed on orally. The present study is the first ethnomedicinal study in Jakholi area of Rudraprayag district of Northwestern India. The aim of present study was to identify traditional medicinal plants used by the inhabitants to treat different ailments and document the associated knowledge of these medicinal plants. An ethnomedicinal survey was carried out in 72 of 133 villages and alpine pastures of Jakholi block (800-4000 m asl). Door to door surveys and group discussions, applying semi-structured questionnaires were conducted with traditional healers and villagers in local language (Garhwali). Informant Consensus Factor (ICF) was computed to analyse collected ethnomedicinal data. A total of 78 species (Gymnosperms 3 species, Monocotyledons 12 and 63 Dicotyledons) belonging to 73 genera in 46 families were identified to treat 14 different ailments categories. Most dominant family is Asteraceae (5 species). In disease treated categories, Diseases of the skin (DE) have the highest proportion (29.55%) followed by Gastro- intestinal disorder (GA) (25.89%). The most life form of plants used was herb (56%) followed by tree (23%) while root was the most frequently used part of the plants and the traditional preparation was mainly applied in the form of paste (37%). The highest ICF value (0.99) was found for hair ailments (HA) followed ophthalmologic complaints (OP) and mental afflictions (MA) (0.98). The present study provides valuable information about traditional knowledge of medicinal plants of Jakholi Block in the Northwestern Himalaya, India. Local communities still possess large traditional knowledge of plants and their therapeutic uses and that the link of that traditional knowledge to modern research could be

1996-01-01

For the determination of the ventilation influence (directional flux of air induced by a fan) on the spatial distribution of Rn-222 and its decay products (daughters) present in human inhabited environments, a group of experimental results were obtained by means of the fission nuclear tracks left by α-particles over adequate plastic detectors CR-39). The exposure of these detectors was done in a closed environment considering the influence of ventilation for different angles, velocities and distances from fan. The results show that a relative quantity of daughters of Rn-222 are pulled out of the environment due to the effects of ventilation and plat-out

Promoting Space Education and Awareness in Pakistan- Initiatives, Achievements, Challenges and Issues

Science.gov (United States)

Jagirani, Aisha

With about 180 million inhabitants, Pakistan is the sixth most populous and the 34th largest country in the world in terms of area. Pakistan's economy, which is pre-dominantly based on agriculture, is the 26th largest in the world in terms of purchasing power parity and 45th largest in terms of nominal GDP. Pakistan is counted among the Next Eleven (N11) countries that have the potential to become the world's largest economies in the 21st century. Despite considerable potential to develop into a stable, moderate and democratic state, major challenges of internal security, poor agricultural productivity, inadequate infrastructure, food insecurity, insufficient health and educational facilities, depletion of natural resources, rapid environmental degradation and recurring natural disasters have burdened the country and have hampered sustainable development of Pakistan. Space technology applications offer a cost-effective means of addressing many of the above mentioned issues and have made impressive advances in the last few years in different countries in the region. Unfortunately, for various reasons, Pakistan has not been able to fully exploit the benefits of space technology and its applications to meet the challenges she faces. One of the reasons is lack of awareness and understanding by planners, decision-makers and users about the potential benefits of space technology in planning and implementation of developmental plans as well as good governance. Similarly, Pakistan's space program enjoys little public support due, primarily, to lack of awareness of the benefits space offers and the ubiquitousness of space applications in modern life. There is thus an acute need to create awareness and educate all segments of the society and stakeholders in Pakistan about the potential benefits of space technology and its applications. In the past ten years, many initiatives have been taken to promote space education and awareness for students as well as decision-makers in

The finite element part of the LAMCAL program. Elastic-plastic fracture mechanics applications

International Nuclear Information System (INIS)

Lamain, L.G.; Blanckenburg, J.F.G.

1982-01-01

The elastic-plastic FEM code described in this report is the third part of the Lamcal program of which the two other parts for mesh generating and plotting were presented previously. Also this part uses the dynamic core storage. All variables and problem defining data are stored in one common array-SPACE. If all three parts are used together, the same common-SPACE is reused in each part. The lay-out of the complete program is given. J-integral evaluation and plotting can be done immediately in the FE run or afterwards in a post processing run. Post processing is done within the FEM part with a reduced core space. Originally developed as a general code, the use of the present version is mainly focussed on research in the field of the fracture mechanics. Several J-integral routines are available as well as crack growth modelling by node release or stiffness reduction, energy calculations, crack tip elements, etc. In this report the theory is discussed and some sample problems are given. The theory is presented in two parts, the general FEM and the more specific EPFM theory. For the sample problems, a choice has been made to show the accuracy of the program under more or less severe loading conditions

Motorization and supermarket-proliferation affect lifestyles. About 15 years ago, Okinawans went to several shops on foot, but now they go to supermarkets by car. The influences of these changes on the prevalence of diabetes are uncertain. OBJECTIVE AND MEASUREMENTS: The influence of motorization and supermarket-proliferation on the prevalence of diabetes was studied in the inhabitants of a town on Okinawa, Japan. Measurements were composed of anthropometry and blood chemistry. Participants were asked where they buy food and daily necessities (several shops or a supermarket) and how they get there (by car or on foot). Serial cross-sectional. Inhabitants of the island of Okinawa were studied. In 1991, 24% went to several shops and 20% to a supermarket. However, in 2004, only 3.1% went to several shops and 83% to a supermarket. In 1991, 55% went to shopping places on foot and 38% by car. However, in 2004, only 14% went on foot and 76% by car. The prevalence of diabetes in Okinawa increased from 4.7% in 1991 to 8.4% in 2004. The prevalence of diabetes correlated positively with the percent of inhabitants going to supermarkets, and those going there by car. In 1991, the prevalence of type 2 diabetes was 4.7% in men and 4.6% in women; no difference was noted between men and women. In 2004, the prevalence of type 2 diabetes increased to 9.2% in men and to 7.5% in women. The increase in the prevalence of type 2 diabetes from 1991 to 2004 was higher in men than in women. About 15 years ago, Okinawans went to shops on foot, but now they go to supermarkets by car. The prevalence of diabetes is increasing. Motorization and supermarket-proliferation are associated with the increases of the prevalence of diabetes. The increase in diabetes prevalence was higher in men than in women.

The 'k 0 -method' of neutron activation analysis has been tested for applicability to the determination of trace elements in samples of thyroids of inhabitants from regions in Belarus affected to different degree by thyroid cancer among children after the accident of the Chernobyl power plant. It is shown that the k 0 -method produces results identical to the 'relative method' in neutron activation analysis. Significant differences in the elemental composition of thyroids from the regions of Gomel and Minsk are observed and may be related to the different levels of occurrence of thyroid cancer among children.

Iwanowicz, L; Densmore, C; Hahn, C; McAllister, P; Odenkirk, J

2013-09-01

The Northern Snakehead Channa argus is an introduced species that now inhabits the Chesapeake Bay. During a preliminary survey for introduced pathogens possibly harbored by these fish in Virginia waters, a filterable agent was isolated from five specimens that produced cytopathic effects in BF-2 cells. Based on PCR amplification and partial sequencing of the major capsid protein (MCP), DNA polymerase (DNApol), and DNA methyltransferase (Mtase) genes, the isolates were identified as Largemouth Bass virus (LMBV). Nucleotide sequences of the MCP (492 bp) and DNApol (419 pb) genes were 100% identical to those of LMBV. The nucleotide sequence of the Mtase (206 bp) gene was 99.5% identical to that of LMBV, and the single nucleotide substitution did not lead to a predicted amino acid coding change. This is the first report of LMBV from the Northern Snakehead, and provides evidence that noncentrarchid fishes may be susceptible to this virus.

The neighborhood of Vallcarca, Barcelona - Spain, is located near the valley formed by the three hills called El Putxet, Creueta del Coll and Muntanya Pelada adjacent to the back area of Park Guell. Vallcarca first urbanized at the XIX century as a place to spend summer for the nearby inhabitants of the city of Barcelona. Since the end of XX century, the area has been under the pressure of different urban plannings and economic speculations that have just erase a big portion of its original physiognomy, without being able to organize a new area of town. The empty land that located at the former center and across Vallcarca becoming part of research to produce an outcome for compatible housing within the area. The data gives a focus on the social and urban rehabilitation of the neighborhood that introducing a program of social housing with communal facilities using an approach of connection and topography that existed on the site as a catalyst to change this fragmented part of the city into inclusive neighborhood.

Full Text Available ACCESSIBILITY AND USE OF URBAN GREEN SPACES IN THE CITIES OF COIMBRA (PORTUGAL AND SALAMANCA (SPAIN. In a society that values more and more wellbeing, health and free time, the introduction of urban green spaces (UGS next to residential areas has become a citizen’s right and requirement. This paper analyses the distribution and accessibility of UGS in the cities of Coimbra and Salamanca and evaluates their influence on the needs of the resident populations, in terms of users’ age, frequency of usage, as well as of motivation and ways to enjoy the facilities. In Coimbra there is a concentration of UGS, whereas in Salamanca there is a dispersion of such spaces, which has resulted in the different usage that people make of them. In fact, although Coimbra offers more urban green space (per inhabitant, their usage is reduced as people go there mainly by car, contrary to what happens in Salamanca. Consequently, Coimbra’s inhabitants choose these green spaces because of the activities they can be used for, whereas Salamanca’s inhabitants choose them for their proximity.

Space Law and China

Science.gov (United States)

Tronchetti, Fabio

2017-08-01

Over the past few years, China has made remarkable achievements in the space sector and become one of the most relevant players in the outer space domain. Highlights of this process have been the deployment in orbit of the first Chinese space station, Tiangong-1, on September 29, 2011; and the landing of the Yutu rover on the lunar surface on December 14, 2013. While technological developments have occurred at such a rapid pace, the same cannot be said of the regulatory framework governing Chinese space activities, which still lays at its infant stage. Indeed, unlike other major space-faring countries, China lacks comprehensive and uniform national space legislation; as of now, China has enacted two low-level administrative regulations addressing the issues of launching and registration of space objects. With the growth of the Chinese space program, such a lack of a structured national space law is beginning to show its limits and to create concerns about its negative impact on business opportunities and the ability of China to fully comply with international obligations. One should keep in mind that the international space treaties (China is part to four international space law treaties) are not self-executing, thus requiring States to adopt domestic measures to ensure their effective implementation. Importantly, Chinese authorities appear to be aware of these issues; as stated by the secretary-general of the Chinese National Space Administration (CNSA) in 2014, national space law has been listed in the national legislation plan and the CNSA is directly engaged in such a process. However, questions remain as to how this drafting process will be conducted and what legal form and content the law will have. For example, China could either decide to proceed with a gradual approach, consisting in the adoption of laws addressing selected issues to be eventually assembled into one single law; or to directly move to the adoption of one comprehensive law. In any case, if

The sacred space becomes an important part of the spatial layout of Javanese society, as well as in most houses of the archipelago. This space is related to religious activities, highly respected and usually located in the main place. Kudus Kulon community is a part of Javanese culture in the northern coastal area of Java. Known as a devout Muslim society, sacred space in Kudus Kulon community house becomes an important thing to understand the culture of living in society. The research was conducted by looking at the religious activities of the community and how the space of activity is realized. The research was conducted by qualitative research method. In the Kudus Kulon community, sacred spaces are available in the house itself, in the community grup of houses, and around Kudus Kulon area. In every house, the sacred space can be found in Gedongan and extends to Dalem. In the community group of houses, the sacred space can be found in the neighbourhood praying area, while In Kudus Kulon area, it can be found in Mosque complex and Tower tomb. Physically sacred space is realized by raising the floor height of the space around it. In architectural view, the sacred space is seen on the elevation of the roof or roof angle. Spatially the sacred space occupies a central position and visually represented by a vertical orientation.

Global risk & global challenges - Space as a game changer for socioeconomic sustainable development

Lehnert, Christopher; Karlsson, Evelina; Giannopapa, Christina

2017-11-01

The world's societies at the beginning of the 21st century are better off than ever before. (Gapminder, 2015) At the same time, the world is also threatened by global challenges where space as a tool has and can play a pivotal role in meeting those challenges. The challenges range from climate change, over mass unemployment, to terrorism or migration - to name but a few. Space activities have started to respond to this changing world, not only by providing a deeper understanding of our universe, but by using space as an additional sphere and sector, through which humankind can increase and secure its wealth - it is thus game changing in the way we sustain humanity's existence. This paper is meant to capture this development. In the first part, an overview is given on the risks that humankind is facing.
