    Expectations as to the climate potentials of nanotechnology are high, none the least related to the construction sector. This paper seeks to highlight key aspects in the early development and application of eco-innovative nanotech solutions in the construction sector, “nanoconstruction”. The paper provides a framework for addressing relevant issues of green nanoconstruction and takes stock of current challenges. Eco-innovative nanoconstruction has the potential to simultaneously enhance the competitiveness and climate potential of the construction sector and could become a key strategic factor for the sector ahead. However, the considerable lack of knowledge both on the eco-opportunities and risks of nanoconstruction and the industrial dynamics involved forms a serious barrier for pursuing nanoconstruction as a serious strategic target for business and policy.

  7. Societal embedding of climate-friendly innovations

    International Nuclear Information System (INIS)

    This project assesses the possibilities of constructing a market for climate-friendly energy technologies by applying the process of 'societal embedding of innovations'. The term refers to an interactive learning process amongst three groups of key actors: producers, users and societal actors. Their co-operation shapes the innovation to fit the needs of the market and contributes to creation of conditions in which the innovation can be adopted. The project consists of two case studies: (1) Shaping of the ESCO energy service concept in Finnish municipalities and (2) Increasing the use of wood pellets in single-family houses. The case studies have illustrated the possibilities and limitations concerning the application of societal embedding in the energy sector. The project indicates that societal embedding may promote the implementation of climate-friendly energy technologies in at least three ways. Firstly, the process mobilises key actors to cooperation. This generates interactive learning on the problem and its solving. Market construction is forged ahead by mutual adaptation of the innovation and its environment. Secondly, this approach offers a tool to examine the societal quality of the innovation, a question related vitally to climate change. Thirdly, by producing new knowledge of the needs on the market this approach supports the societal actors in choosing different instruments to induce the intended transition to sustainability.

    Indonesia is one country that is highly prone to earthquakes because it is located at the juncture of four tectonic plates, namely the Asian continental shelf, the continental shelf of Australia, the Indian Ocean plate and the Pacific plate. In the southern and eastern parts of Indonesia there is a volcanic belt that extends from the island of Sumatra, Java and Nusa south eastern Sulawesi, the sides in the form of old volcanic mountains and the lowlands are mostly dominated by swamps. The condition of potential and proneness to disasters such as volcanic eruptions, earthquakes, tsunamis, floods, and landslides. Indonesian society have a local knowledge for facing disasters. Local communities in particular areas have local knowledge for facing disasters. Such knowledge is commonly kept by members of the communities and applied to their environments, including houses. This research aims to describe disaster-friendly Sundanese traditional building construction. It employs the evaluation method, by comparing Sundanese traditional house construction to the standards of disaster-friendly construction. The results indicate that the Sundanese traditional building constructions have been qualified as disaster-friendly buildings.

  9. Global climate-friendly trade : Canada's chance to clean up

    International Nuclear Information System (INIS)

    This paper discussed the global trade and investment in climate-friendly technologies, Canada's current position in this market, and the policy changes that are necessary for Canadian businesses to gain a stronger foothold in this sector. The global market for climate-friendly technologies is growing rapidly, but Canadian businesses have generally failed to exploit opportunities to export climate-friendly technologies and have generally lagged other countries in adopting such technologies developed elsewhere. Although Canadian businesses generally underperform in this sector, Canada does have notable strengths in 13 identified areas, including waste management technologies, energy technologies, and in parts of the value chains associated with wind and solar power. Targeting these areas of relative strength for further development could position Canada as a global leader in some climate-friendly technologies. For this to happen, Canadian governments need to establish clear policies, invest in research and development, and remove domestic and international barriers to the development and trade in climate-friendly technologies. 30 refs., 5 tabs., 5 figs.

  10. Risk benefits of climate-friendly energy supply options

    International Nuclear Information System (INIS)

    One of the central goals of sustainable development is the reduction of Greenhouse Gas (GHG) emissions. This is needed in order to prevent the anticipated climate change, and the potentially serious consequences for human beings and the environment. Energy supply systems constitute the dominant contributors to GHG emissions. This paper examines three illustrative emission scenarios for world-wide energy supply in the 21st Century. These scenarios, including the associated GHG and major pollutant emissions, were chosen from a set established by the Intergovernmental Panel on Climate Change (IPCC). Using the emissions as a starting point, and based on recent findings concerning the impact on the environment and the financial costs resulting from global climate change on the one hand, and regional air pollution on the other hand, the present work provides estimates of the scenario-dependent, world-wide cumulative damage. The fossil-intensive reference scenario leads to overall damages which correspond to very substantial losses in Gross Domestic Product (GDP), and which widely exceed the damages caused by the scenarios reflecting climate-friendly policies. Generally, the somewhat speculative estimates of the GHG-specific damages are much less significant than damages to human health and the environment caused by the major air pollutants. This means that the secondary benefits of climate-friendly, energy-supply options, i.e. those which avoid the impacts due to air pollution, alone justify strategies protecting the climate. (author)

  12. Farmer's Friend Biodigester Model Construction Manual

    2005-11-15

    The success or failure of any biodigester depends mainly upon the suitability of the design, site for construction and quality of construction works, as well as quality of construction materials and workmanship involved during construction. This booklet provides the extensive information on various methods for selecting the appropriate size and site for construction, as well as construction work steps related to the Farmer's Friend model (2005) of biodigester. First, mason's responsibilities are explained. Second, the report continues with the sizes of available biodigesters and the quantity of feeding required. Then, the components of the biogas plant and instructions as to how to select the appropriate size are described. It continues with construction materials and appliances, and the selection of the construction site. Finally, the plant construction is explained from lay-out work to the construction of compost pits, finishing work and instructions to users. If the concerned mason/plumber strictly follows the instruction as described in this construction manual, the biodigester will function properly with the anticipated efficiency and the owner will get the return of his/her investment. This will encourage his/her relatives and neighbours to install biodigesters. However, if the biodigester functions poorly, nobody will be motivated to install it. Poor quality plants will harm the reputation of biogas technology and will have serious negative effects on promotion and extension activities. The masons should, therefore, be well aware that good quality plants will certainly increase the rate of installation with the demonstration effect that ultimately benefits itself, the farmer, and the country as a whole.

    Sørensen, Jesper Harrild; Hoang, Linh Cao; Fischer, Gregor; Olesen, John Forbes

    2015-01-01

    The scope of this paper is the shear capacity of in-situ cast joints between precast concrete panels. Current practice with vertical lowering of the wall panels experiences difficulties in the assembly phase, since the traditional U-bar connection requires an overlap in a horizontal plane to allow...... for the mounting of a vertical locking bar. Where limited space is available bending and subsequent straightening of the U-bars are required to assemble the adjacent panels, a procedure which imposes substantial ductility requirements on the reinforcement as well as some manual workload. This paper...... introduces a construction-friendly design with U-bars overlapping in the same plane as the panel itself. The design allows for a trouble-free vertical lowering of the panels without pre or post processing of the preinstalled reinforcement loops. Furthermore, an overall more ductile behavior of the joint is...

    The impact of climate change will resonate through a broad range of fields including public health, infrastructure, water resources, and many others. Long-term coordinated planning, funding, and action are required for climate change adaptation and mitigation. Unfortunately, widespread use of climate data (simulated and observed) in non-climate science communities is impeded by factors such as large data size, lack of adequate metadata, poor documentation, and lack of sufficient computational and visualization resources. We present ClimatePipes to address many of these challenges by creating an open source platform that provides state-of-the-art, user-friendly data access, analysis, and visualization for climate and other relevant geospatial datasets, making the climate data available to non-researchers, decision-makers, and other stakeholders. The overarching goals of ClimatePipes are: - Enable users to explore real-world questions related to climate change. - Provide tools for data access, analysis, and visualization. - Facilitate collaboration by enabling users to share datasets, workflows, and visualization. ClimatePipes uses a web-based application platform for its widespread support on mainstream operating systems, ease-of-use, and inherent collaboration support. The front-end of ClimatePipes uses HTML5 (WebGL, Canvas2D, CSS3) to deliver state-of-the-art visualization and to provide a best-in-class user experience. The back-end of the ClimatePipes is built around Python using the Visualization Toolkit (VTK, http://vtk.org), Climate Data Analysis Tools (CDAT, http://uv-cdat.llnl.gov), and other climate and geospatial data processing tools such as GDAL and PROJ4. ClimatePipes web-interface to query and access data from remote sources (such as ESGF). Shown in the figure is climate data layer from ESGF on top of map data layer from OpenStreetMap.

  3. The social construct of climate and climate change

    International Nuclear Information System (INIS)

    Different time scales of climate change and their differential perception in society are discussed. A historical examination of natural climate changes during the past millennium suggests that short-term changes, especially crucial changes, trigger a significant response in and by society. Short-term changes correspond to the 'time horizon of everyday life', that is, to a time scale from days and weeks to a few years. The anticipated anthropogenic climate changes, however, are expected to occur on a longer time scale. They require a response by society not on the basis of primary experience but on the basis of scientifically constructed scenarios and ways in which such information is represented in the modern media for example. Socio-economic impact research relies on concepts that are based on the premise of perfectly informed actors for the development of optimal adaptation strategies. In contrast to such a conception, we develop the concept of a 'social construct of climate' as decisive for the public perception of scientific knowledge about climate and for public policy on climate change. The concept is illustrated using a number of examples. (orig.)

    Stabilizing global greenhouse gas concentrations at levels to avoid significant climate risks will require massive "decarbonization" of all the major economies over the next few decades, in addition to the reduced emissions from other GHGs and carbon sequestration. Achieving the necessary scale of emissions reductions will require a multifaceted policy effort to support a broad array of technological and behavioral changes. Change on this scale will require sound, well-thought-out strategies. In this article, we outline some core principles, drawn from recent social science research, for guiding the design of clean technology policies, with a focus on energy. The market should be encouraged to make good choices: pricing carbon emissions and other environmental damage, removing distorting subsidies and barriers to competition, and supporting RD&D broadly. More specific policies are required to address particular market failures and barriers. For those technologies identified as being particularly desirable, some narrower RD&D policies are available.

    Full Text Available Although significant changes at the social, demographic, technological and workforce levelshave transformed the relationship between family and work, these changes have notbeen reflected in the employment practices of many construction companies. Many of thejob and organisational factors found to be negatively associated with family functioning arepertinent to construction professionals. Staff are expected to work long hours in demandingroles and this, combined with job insecurity and frequent relocation, means that familylife and individual well-being can be compromised. A growing body of research has foundthat the implementation of family-friendly work policies and practices can lead to greaterproductivity, lower attrition rates and higher morale in the workplace. In addition providinga work environment that is supportive of workers' family roles can help to alleviate workrelatedmental health problems.This paper outlines the changing demographic trends and societal attitudes that are makingindividuals and organisations question current work cultures and structures. Optionsfor making the construction industry a more family-friendly work environment are considered.All professionals, regardless of their age, gender and family responsibilities, canbenefit from these initiatives. The paper concludes by discussing the implications of theseissues for construction companies and future research work.

    Full Text Available A large percent of CO2 (carbon dioxide emissions in Serbia originate from transport. In the last two decades, the number of private car users in Belgrade evidently increased compared to the number of users of environmentally friendly modes of transport. The purpose of this paper is to present an overview of approaches to the improvement of the physical aspect of the open public spaces, which aim to increase the number of users of climate friendly modes of transport, particularly walking. Research was done using three methods: observation of the intensity of pedestrian movement in relation to different periods during the day, direct surveys of citizens and the evaluation of immediate pedestrian surroundings. Three kinds of results were obtained: the trends and concentration of pedestrian movement along the main street lines; the attitude of citizens pertaining to reliable pedestrian movement and elements which contribute to their commitment to walking; and the rhythm of activity units, transparency, and variety of activities on the ground floor of buildings. The contribution of the study is in combining different research methods. The interpretation of the results forms the basis for directing future research and campaigns on topics of climate friendly modes of transport in urban areas.

    Information confidentiality is an essential requirement for cyber security in critical infrastructure. Identity-based cryptography, an increasingly popular branch of cryptography, is widely used to protect the information confidentiality in the critical infrastructure sector due to the ability to directly compute the user's public key based on the user's identity. However, computational requirements complicate the practical application of Identity-based cryptography. In order to improve the efficiency of identity-based cryptography, this paper presents an effective method to construct pairing-friendly elliptic curves with low hamming weight 4 under embedding degree 1. Based on the analysis of the Complex Multiplication(CM) method, the soundness of our method to calculate the characteristic of the finite field is proved. And then, three relative algorithms to construct pairing-friendly elliptic curve are put forward. 10 elliptic curves with low hamming weight 4 under 160 bits are presented to demonstrate the utility of our approach. Finally, the evaluation also indicates that it is more efficient to compute Tate pairing with our curves, than that of Bertoni et al. PMID:27564373

    2010-06-01

    Full Text Available Safety in the construction industry has always been a major issue. Though much improvement in construction safety has been achieved, the industry still continues to lag behind most other industries with regard to safety. The safety climate of any organization consists of employee’s attitudes towards and perceptions of, health and safety behavior. Construction workers attitudes towards safety are influenced by their perceptions of risk, management, safety rulesand procedures. A measure of safety climate could be used to identify those areas of safety that need more attention and improvement. The dynamic nature of safety climate, which has the ability to change on daily basis, means there is a great need for reliable tools that can measure safety climate. Safety climate is a leading performance indicator that can provide insight into safety performance before accidents have occurred. In the present study a questionnaire was framed to ascertain safety climate in major construction rganizations across India involved in construction of Thermal power plants, Hydro power plants, Highway projects, Bridge works, Refinery works, High rise works, Pipe line works and Dam woks and its content validity was verified. The internal consistency of the questionnaire was tested by using Cronbachs alpha coefficient. Data was collected based on questionnaire from employees working in various construction firms in India. The results of questionnaires survey was tested statistically by using the Kruskal – Wallis test to ascertain the attitudes of different categories of employees towards safety climate.

  13. Spurring climate-friendly behaviour change: a case study of the university of Grenoble

    International Nuclear Information System (INIS)

    % of energy consumption. 'Energy vampires' at home (i.e. the standby power of all electric and electronic devices) represent almost 11% of US energy use. Two similar daily diets in terms of energy intake may differ by a factor of four in terms of life-cycle energy inputs, depending on the content of the diet. Although the cumulative potential gains drawn from individual actions are substantial, they may be hard to reach in reality, because barriers are numerous for individuals to change their behaviour and actually reduce their greenhouse gas emissions. Even individuals with positive attitudes may show much reluctance to behave in a climate-friendly way. Against this background, our paper aims to investigate how these barriers can be overcome so that individuals take action. The investigation that we carry out relies on a climate-friendly initiative that has been going on at the university of social sciences of Grenoble, France, for six years. The goal of the initiative is to stabilize the greenhouse gas emissions of the university in 2010 relative to 1999. Various actions have been taken, such as building a greenhouse gas emissions inventory to monitor those emissions, improving the efficiency of the heating system, organizing internal communication campaigns to help people reduce their carbon footprint. Only a few people are currently acting, although all members of the university could be contributing to reducing the university's emissions. Various barriers prevent them from acting. The first part of the paper presents the university actors, and their mission in the climate-friendly initiative. The second part identifies the university members' main motivations and barriers to a climate-friendly behaviour. Finally, the third part discusses potential ways of overcoming those barriers, calls for an inter-disciplinary research program to successfully address the issue. It should be noted that the methodology adopted in the paper, the barriers

    Food consumption comprises a significant portion of the total environmental impact of households. One way to reduce this impact may be to offer consumers more climate-friendly meal choices, such as when eating out. However, the environmental benefits of such an intervention will depend on not only consumers' liking of the climate-friendlier meals, but also on the perceived environmental impact. We therefore investigated the relationship between the global warming potential (GWP) of and consumers' liking of meals in two field studies in the same restaurant. Visitors to the restaurant were asked to rate the taste of the meal they had just consumed. These taste ratings were then related to the meals' GWP and number of purchases. In the second study, an intervention was tested consisting of a climate-friendly choice label and information posters. Contrary to expectations, it was found in both studies that the GWP of the meals was unrelated to the taste or the number of purchases. Offering more climate-friendly meals did not change consumer satisfaction. As expected, the introduction of the climate-friendly choice label increased the number of climate-friendly meal purchases. Therefore, offering more climate-friendly meals with a climate-friendly choice label can affect consumers' meal choices, but not their preferences or satisfaction, which is beneficial for the climate, consumers and gastronomic establishments.

  16. Lobbying friends and foes in climate policy: The case of business and environmental interest groups in the European Union

    International Nuclear Information System (INIS)

    Drawing on two conflicting hypotheses from the theoretical literature on lobbying, I consider the strategies applied by interest groups lobbying to influence climate policy in the European Union (EU). The first hypothesis claims that interest groups lobby their 'friends', decision-makers with positions similar to their own. The second claims that interest groups lobby their 'foes', decision-makers with positions opposed to their own. Using interviews with lobbyists and decision-makers, I demonstrate that in the field of climate policy, interest groups in the EU lobby both friends and foes, but under different conditions. Moreover, I find that the interest groups' motives are not always in line with the theoretical hypotheses. Interest groups lobby their friends on single policy decisions to exchange information, to further a common cause and to exert pressure, and their foes because a foe on one issue might prove to be a friend on another issue. Interest groups direct general lobbying towards both friends and foes. This paper provides a new empirical contribution to a literature that has so far been heavily dominated by studies focusing on lobbying in the US

    Safety in the construction industry has always been a major issue. Though much improvement in construction safety has been achieved, the industry still continues to lag behind most other industries with regard to safety. The safety climate of any organization consists of employee’s attitudes towards and perceptions of, health and safety behavior. Construction workers attitudes towards safety are influenced by their perceptions of risk, management, safety rulesand procedures. A measure of safe...

  19. Greenhouse gas balances in low-productive drained boreal peatlands - is climate-friendly management possible?

    Ojanen, Paavo; Minkkinen, Kari; Heikkinen, Tiina; Penttilä, Timo

    2016-04-01

    Five million hectares of peatland has been drained for forestry in Finland. About 20% of that, i.e. one million hectares, has been estimated to be so low-productive that the profitability of keeping them in forestry is questionable. At the same time, drainage has introduced changes in the ecosystem functions of these peatlands, including fluxes of greenhouse gases. Options to manage such peatlands include for example 1) no measures, i.e. leaving the drained peatlands as they are 2) increasing intensity by e.g. repetitive fertilisations and 3) restoration back to functional peatlands. Here we estimate the greenhouse gas impacts of these three management options. We collected GHG and organic carbon flux data from 50 low-productive peatlands under these management options over two years 2014-2015. Gas fluxes (CO2, CH4, N2O) were measured with closed chambers. Litter production rates of different plants above and below ground were estimated using litter traps (trees), biomass sampling (roots), through-grow nets (mosses), allometric biomass models (other vasculars) and published turnover rates (roots, other vasculars). Characteristics for estimating tree stand biomass increment were measured at each site from circular sample plots. In this presentation we will estimate the GHG impacts for the different management options, and aim to find the most climate-friendly options for the management of low-productive peatlands in the short and long term. This work was funded by Life+ LIFE12/ENV/FI/150.

  20. Development of Exhibit on Arctic Climate Change Called The Arctic: A Friend Acting Strangely Exhibition

    Energy Technology Data Exchange (ETDEWEB)

    Stauffer, Barbara W.

    2006-04-01

    The exhibition, The Arctic: A Friend Acting Strangely, was developed at the Smithsonian Institution’s National Museum of Natural History (NMNH) as a part of the museum’s Forces of Change exhibit series on global change. It opened to the public in Spring 2006, in conjunction with another Forces of Change exhibit on the Earth’s atmosphere called Change Is in the Air. The exhibit was a 2000 square-foot presentation that explored the forces and consequences of the changing Arctic as documented by scientists and native residents alike. Native peoples of the Arctic have always lived with year-to-year fluctuations in weather and ice conditions. In recent decades, they have witnessed that the climate has become unpredictable, the land and sea unfamiliar. An elder in Arctic Canada recently described the weather as uggianaqtuq —an Inuit word that can suggest strange, unexpected behavior, sometimes described as that of “a friend acting strangely.” Scientists too have been documenting dramatic changes in the Arctic. Air temperatures have warmed over most—though not all—of the Arctic since the 1950s; Arctic precipitation may have increased by as much as 8%; seasonal melting of the Greenland Ice Sheet has increased on average by 16% since 1979; polar-orbiting satellites have measured a 15¬–20% decline in sea ice extent since the 1970s; aircraft reconnaissance and ship observations show a steady decrease in sea ice since the 1950s. In response to this warming, plant distributions have begun to shift and animals are changing their migration routes. Some of these changes may have beneficial effects while others may bring hardship or have costly implications. And, many scientists consider arctic change to be a ‘bell-weather’ for large-scale changes in other regions of the world. The exhibition included text, photos artifacts, hands-on interactives and other exhibitry that illustrated the changes being documented by indigenous people and scientists alike.

  1. Noticing climate change in electricity network design and construction

    International Nuclear Information System (INIS)

    The climate change is widely known to cause remarkable effects to electricity network systems on the whole. Some of the changes are good but the most of the changes cause disadvantages to electricity network. Consequence of climate change, blackouts can be long-standing which affect remarkable society and economic life. Most of electricity networks are coming to a renovation phase and the solutions, that are being made nowadays, affect still after decades. Taking account of climate change, now when networks are being developed and planned, it is possible to avoid possible large repair operation and increase reliability of distribution in the future. The aim of this project is to clarify how climate change should be noticed in planning and construction processes. According to the results of this project electricity network companies can be prepared for climate change by developing planning processes and network cost effectively. Also construction processes are being developed but emphasis is on planning process. The results and developed knowledge of VTT research project 'Impacts of climate change on electricity network business' are exploited in this project. In addition, impacts of climate change on cables and transformers are analyzed in collaboration with TKK in the project. (orig.)

  5. Utilization of Geospatial Techniques for Extraction of Suitable River Islands for Construction of Eco-Friendly Tourism Places

    Science.gov (United States)

    Kuldeep, K.

    2015-12-01

    In India, most of the rivers form big size natural islands due to change in its course. However, identification of suitable river island is a very challenging task since these are exposed to river flooding. River islands with least vulnerability to the impacts of severe flooding can be a suitable place for construction of tourism destination such as eco-friendly Parks, Hotels etc. The study involves a two step approach viz. automatic extraction of river islands and model development for flood inundation mapping for extraction of eco-friendly tourism destinations. In this study, automatic extraction of the river islands has been carried out using knowledge based classification approach. The satellite data acquired by the Indian Remote Sensing Satellites sensors such as LISS-III and Cartosat-1 DEM have been used for analyses. In the first step, satellite imagery has been broadly categorized into 5 landuse/cover classes viz. Water, Sand, Islands, Settlements and Cropland. Extraction of such islands which remain unaffected during severe flooding has been accomplished with the flood inundation mapping which has been carried out in HEC-GeoRas with in GIS environment. The model utilizes the primary 4 inputs viz. geometry of the river (DEM, slope), time series data of water surface elevation, landuse/cover, and location of rain gauge station for flood inundation mapping. This paper also investigates the applicability of the eco-island concept to include protection of wetland, management of land-resources, sustainable use of natural resources and construction of ecological park/hotels. The output of the study will be very helpful for Government authorities in stabilizing economy, and enhancing the tourism infrastructure in a better way.

  6. Does Introducing more User-friendly Software Produce better Integrated Learning in an Undergraduate Course on Climate Modelling?

    Science.gov (United States)

    Fletcher, C. G.

    2015-12-01

    Appropriate use of technology in the classroom can help to integrate content and process learning; however, there are multiple barriers to introducing technological aids in the classroom that can reduce their effectiveness. In this pilot study we evaluate the impact on student learning from switching to more user-friendly software for lab assignments in an undergraduate course on climate modelling. Computer programming-based labs are replaced by a menu-driven modelling application called EdGCM, developed by Columbia University and the NASA Goddard Institute for Space Studies. The EdGCM tool allows students to explore and visualize a wider array of aspects of climate variability and change—and in greater depth—than was possible previously. The goals of this study are (i) to make the course material more accessible to students regardless of their computing background; and (ii) to improve the level of students' knowledge retention in core climate science concepts. The impact of the change in software is measured using a combination of class surveys and students' test scores. Differences in the level of integration between content and process learning, compared to previous iterations of the course without EdGCM, are discussed.

  8. A suite of user-friendly global climate models: Hysteresis experiments

    Science.gov (United States)

    Fraedrich, K.

    2012-05-01

    A hierarchy of global spectral circulation models is introduced ranging from the shallow-water system via the primitive-equation dynamical core of the atmosphere to the Planet Simulator as a Global Climate Model (GCM) of Intermediate Complexity (MIC) which can be used to run climate and paleo-climate simulations for time scales up to ten thousand years or more in an acceptable real time. The priorities in development are set to speed, easy handling and portability with a modular structure suitable for problem-dependent configuration. Adaptions exist for the planetary atmospheres of Mars and of Saturn's moon Titan and are being extended. Common coupling interfaces enable the addition of ocean, ice, vegetation models and more. An interactive mode with a Model Starter and a Graphical User Interface (GUI) is available to select a configuration from the available model suite, to set its parameters and inspect atmospheric fields while changing the models' parameters on the fly. This is especially useful for teaching, debugging and tuning of parameterizations. An updated overview of the model suite's features is presented based on the Earth-like climate model Planet Simulator with mixed-layer ocean introducing static and memory hysteresis in terms of a parameter sweep of the solar constant and CO2 concentrations. The static hysteresis experiment demonstrates that the solar constant varying by 20% reveals warm and snowball Earth climate regimes depending on the history of the system. This hysteresis subjected to a thermodynamic analysis shows the following features: i) Both climate regimes are characterized by global mean surface temperature and entropy growing with increasing solar constant. ii) The climate system's efficiency decreases (increases) with increasing solar constant in present-day warm (snowball) climate conditions. iii) Climate transitions near bifurcation points are characterized by high efficiency associated with the system's large distance from the stable

  9. City carbon budgets: A proposal to align incentives for climate-friendly communities

    International Nuclear Information System (INIS)

    Local governments can have a large effect on carbon emissions through land use zoning, building codes, transport infrastructure investments, and support for transportation alternatives. This paper proposes a climate policy instrument - city carbon budgets - that provides a durable framework for local governments to reduce greenhouse gas emissions. Local governments would be assigned an emissions 'budget', and would be required to keep annual local transport and buildings emissions within this budget. This policy framework could be implemented and managed by a higher-level government, or might be used in awarding funds to developing country cities from international climate funds. The state of California has enacted a version of this policy. In this paper, we identify and evaluate options for creating an effective and acceptable institutional structure, allocating emission targets to localities, measuring emissions, providing flexibility and incentives to local governments, and assuring compliance. We also discuss the likely costs of such a policy.

  11. Financing of climate-friendly projects in Slovakia: when if not now?

    International Nuclear Information System (INIS)

    Regarding to the Kyoto Protocol of December 1997 the United Nations agreed on several conventions to stabilise the world climate and to reduce greenhouse gases (GHG), respectively. The international conferences on climate change in Buenos Aires and in Bonn in 1998 and 1999 established concrete steps towards efficient international climate change policy options. The explicit accomplishment of the Kyoto mechanisms, Joint Implementation (JI), Emissions Trading (ET) and the Clean Development Mechanism (CDM) were established. Mechanisms JI and ET are applicable to Slovakia and other parties included in Annex B of the Kyoto Protocol, while CDM is applicable only to 'non-Annex B' countries. Project finance potential from Kyoto-related sources is not fully exhausted in Slovakia yet. Notorious reason is the same -lack of information available to the decision-making personalities. Where, how and with whom the appropriate action has to be undertaken? Miscellaneous practical guidelines offer extra paragraphs entitled Frequently Ask Questions (FAQ) which however, are rarely replied. Reason is simple: very few potential project developers even know what to ask and if they know, they do not know whom to ask. Technical expertise of dedicated financial advisors and consultants have not been fully employed yet and therefore majority of financing resources are idle or waiting for the more aggressive entrepreneurs coming from the neighbouring candidate countries.

  14. Introduction of subsidisation in nascent climate-friendly learning technologies and evaluation of its effectiveness

    International Nuclear Information System (INIS)

    Given its importance as a practical phenomenon underlying the progress of learning technologies, attention should be paid to the role of subsidisation in learning theory, particularly in the case of nascent climate-related sociable learning technologies, in order to examine its benefits. Thus, this study focuses on subsidy procurement of energy technologies in several economies in the context of the component learning track in endogenous global clusters in order to suggest improvements to the adoption mechanism and examine the climate stabilization constraint. At the same time, the study attempts to determine the global progress ratio of the lithium-ion battery in order to analyse various endogenous learning scenarios for hybrid technologies. An integrated energy system model with highly disaggregated global regions (DNE21+) is used to execute this research in a medium time frame. Subsidisation of the learning track of battery technology encourages greater development of plug-in hybrid vehicles, promotes early diffusion of hybrid technologies, and relieves heavy dependency on crude oil and biofuels. The subsidies in the common learning domains in few economies benefit the nearby economies because of the technology spillover that occurs through numerous cross-feedback learning mechanisms. Endogenous learning with subsidies augments diffusion potentials, abates emissions, and shifts sectoral emissions.

    2012-07-01

    Board of Agriculture has developed a basis for the role of agriculture in a road map towards a Sweden without a net greenhouse gas emissions in 2050. One possible reference scenario of how the development would be of no action is taken is presented in the report. Measures that can reduce greenhouse gas emissions from agriculture is discussed as well as instruments that could make the measures came about. Greenhouse gas emissions from agriculture depends largely on what is produced, and are therefore governed by what is consumed. Production can be made more efficient but not without any emission of greenhouse gases. According to the Swedish climate report 7.9 million tonnes of CO{sub 2} equivalent was released in the form of methane and nitrous oxide from livestock keeping and crop production in the agricultural sector in 2010. The report's reference scenario for agriculture is based on the assumption that the Swedish agricultural production in 2050 should be the same as today. The efficiency and productivity is expected to increase - productivity by 0.5 percent per year - which means that emissions of greenhouse gases decreases compared to 2010. The estimated emissions of methane and nitrous oxide from agriculture in 2050 amounts to 7.23 million tonnes CO{sub 2}-equivalent. In the national climate change reporting, the climate impact of agriculture also includes other flows of greenhouse gases than those in the agricultural sector. This applies to uptake and carbon dioxide emissions from land use, greenhouse gas emissions in direct energy use (energy use in stationary machines and fuel use in mobile machines), and greenhouse gas emissions from the production of imported input goods. When these flows are included in total emissions in the reference scenario in 2050, 9.49 million tonnes of CO2 equivalents will be emitted. Relevant measures the farmers themselves can take have been analyzed in terms of the effect they can make as well as cost-effectiveness and

    Full Text Available  Safety issues have always been put forward as one of the major problems and primary concerns in construction industries in many countries. This paper will focus on the impact of safety training on safety climate and its relevant factors in two sites of a construction firm. The Health and Safety Executive (HSE guide to safety climate tool that had been validated in Iran was used to determine the impacts of safety training on safety climate and its relevant factors. For this purpose, 347 workers filled out the questionnaire before and after safety training. The relationships between demographic features of workers and safety climate factors were considered in the questionnaire. Spearman's rho test was used to determine the relationship between safety climate factors. In both sites, there were significant differences (p<0.05 between safety climate factors before and after safety training while, the level of safety climate in both sites was the same before (p=0.416 and after (p=0.547 safety training. The results of Spearman's correlations test indicated that there has been a significant relationship (p<0.05 between safety climate and its relevant factors in both sites. The results showed that some safety climate factors such as pressure for production had been influenced by demographic factors such as age and job category. Safety training can improve the level of safety climate and its relevant factors in a construction industry. Improvement of each safety climate factor can promote the level of safety climate. Demographic features affected safety climate level and its relevant factors.

  5. The clean development mechanism for joint implementation of nuclear power projects in developing countries : a win-win strategy for climate-friendly development

    International Nuclear Information System (INIS)

    The high energy use per capita that characterized most developed countries evolved almost free of constraints external to the market-place. Now, driven by concerns about global climate change and environmental degradation, these countries are being forced to seek climate friendly ways to preserve their enviable quality of life. Success will not come without considerable cost, but there is growing awareness that failure to act will be even more expensive. This recognition has already begun to focus increased attention and investment on conservation and efficiency measures, and on the development of renewable, non- Co2 emitting energy sources (wind, solar electric etc.). At present, it is an open question whether gains in efficiency and expansion of renewable energy sources will suffice. The answer depends in part on developing better models of how the global climate will respond to various levels of GHG in the atmosphere. Another ten years or so may suffice to get the picture clear. But whatever the details, few would argue in favour of additional large increases in GHG emissions, or of severely curtailing development plans of the less-well-off nations. The Climate Convention attests to the world-wide recognition that action on some scale will be obligatory. As we get the problem in better focus, it is important to put all choices on the table for discussion, and to keep all options open. Solving the problem will cost money, probably a lot of it, and finding the most cost-effective approach will be important

  6. Systematic impact of institutional pressures on safety climate in the construction industry.

    He, Qinghua; Dong, Shuang; Rose, Timothy; Li, Heng; Yin, Qin; Cao, Dongping

    2016-08-01

    This paper explores how three types of institutional pressure (i.e., coercive, mimetic and normative pressures) systematically impact on the safety climate of construction projects. These impacts are empirically tested by survey data collected from 186 questionnaires of construction companies operating in Shanghai, China. The results, obtained by partial least squares analysis, show that organizational management commitment to safety and employee involvement is positively related to all three institutional pressures, while the perception of responsibility for safety and health is significantly influenced by coercive and mimetic pressure. However, coercive and normative pressures have no significant effect on the applicability of safety rules and work practices, revealing the importance of external organizational pressures in improving project safety climate from a systematic view. The findings also provide insights into the use of institutional forces to facilitate the improvement of safety climate in the construction industry. PMID:26706434

    The period of active acclimatization was determined for construction workers coming into a subtropical climate. Changes were observed in metabolic processes, oxygen needs, pulse rate, arterial pressure, body and skin temperature, body weight, water consumption and loss, and the comfort zone of heat sensitivity. It was concluded that acclimatization is facilitated if introduction to the hot climate occurs in the mild cool season, rather than the summer. This also prevents heat prostration and improves the development of adaptive mechanisms.

    Safety climate measurements can be used to proactively assess an organization's effectiveness in identifying and remediating work-related hazards, thereby reducing or preventing work-related ill health and injury. This review article focuses on construction-specific articles that developed and/or measured safety climate, assessed safety climate's relationship with other safety and health performance indicators, and/or used safety climate measures to evaluate interventions targeting one or more indicators of safety climate. Fifty-six articles met our inclusion criteria, 80% of which were published after 2008. Our findings demonstrate that researchers commonly defined safety climate as perception based, but the object of those perceptions varies widely. Within the wide range of indicators used to measure safety climate, safety policies, procedures, and practices were the most common, followed by general management commitment to safety. The most frequently used indicators should and do reflect that the prevention of work-related ill health and injury depends on both organizational and employee actions. Safety climate scores were commonly compared between groups (e.g. management and workers, different trades), and often correlated with subjective measures of safety behavior rather than measures of ill health or objective safety and health outcomes. Despite the observed limitations of current research, safety climate has been promised as a useful feature of research and practice activities to prevent work-related ill health and injury. Safety climate survey data can reveal gaps between management and employee perceptions, or between espoused and enacted policies, and trigger communication and action to narrow those gaps. The validation of safety climate with safety and health performance data offers the potential for using safety climate measures as a leading indicator of performance. We discuss these findings in relation to the related concept of safety culture and

    2009-11-01

    This paper argues that Entertainment-Education (E-E) is a striking communication strategy for reaching middle and lower socio-economic classes with climate-friendly lifestyle messages. On the international level (e.g. in the US and the Netherlands) E-E approaches are being theoretically grounded, whereas in Germany they are not yet. Therefore further theoretical discussion and mapping of E-E approaches is central for future research. As a first step towards providing further theoretical foundations for E-E in the field of sustainability, the authors suggest a threefold mapping of E-E approaches. The threefold mapping of E-E approaches for communicating climate-friendly lifestyles to middle and lower class consumers is based on recent results from academic research and practical developments on the media market. The commonalities among the three is that they all promote pro-sustainability messages in an affective-orientated rather than cognitive-orientated, factual manner. Differences can be found in: the sender of the sustainability message, the targeted consumer groups and the media approach in use. Based on this, the paper draws the conclusion that two new paths for further research activities in the field of Entertainment-Education can be proposed: (1) Improving the existing approaches in practice by using theoretical foundation from the E-E field. This comprises at its core (A) to do formative, process and summative effect research on the messages and (B) to use E-E theory from the field of social psychology, sociology and communication science for further improvement and (2) Generating new E-E theories by analyzing the existing practical approaches in the media to communicate climate change.

    Complex network theory provides a powerful framework to statistically investigate the topology of local and non-local statistical interrelationships, i.e. teleconnections, in the climate system. Climate networks constructed from the same global climatological data set using the linear Pearson correlation coefficient or the nonlinear mutual information as a measure of dynamical similarity between regions, are compared systematically on local, mesoscopic and global topological scales. A high degree of similarity is observed on the local and mesoscopic topological scales for surface air temperature fields taken from AOGCM and reanalysis data sets. We find larger differences on the global scale, particularly in the betweenness centrality field. The global scale view on climate networks obtained using mutual information offers promising new perspectives for detecting network structures based on nonlinear physical processes in the climate system.

    The study presented in this paper aims to identify prominent risks leading to heat illness in summer among construction workers that can be prioritised for developing effective interventions. Samples are 216 construction workers' cases at the individual level and 26 construction projects cases at the organisation level. A grounded theory is generated to define the climatic heat and psychosocial risks and the relationships between risks, timing and effectiveness of interventions. The theoretical framework is then used to guide content analysis of 36 individual onsite heat illness cases to identify prominent risks. The results suggest that heat stress risks on construction site are socially constructed and can be effectively managed through elimination at supply chain level, effective engineering control, proactive control of the risks through individual interventions and reactive control through mindful recognition and response to early symptoms. The role of management infrastructure as a base for effective interventions is discussed. PMID:26674401

    Ditterent consumption patterns have different erects on me envtronment, The traditional consumption pattern is supported by a large number of resources and energy consumption, pursuing of short-term objectives and meeting the contemporary human consumption, encouraging deformed consumption and excessive consumption, causing great harm to the development and the environment, and has become the world's main reason for the worsening environmental problems. Therefore, it is imperative to change the existing conventional consumption pattern, and to build a pattern help to sustainable development, environment-friendly consumption. To construct an environment-friendly consumption pattern, we must first change the concept of unsustainable consumption; second, will serve a civilized, healthy, scientific way of life as the basic direction of the current way of life;third, we must establish a sound environmental policy system to promote the development of an important guarantee for sustainable consumption from system level; fourth, we should vigorously develop the circular economy, encouraging consumers to adopt environmentally friendly consumption.%不同的消费模式对环境具有不同的影响.传统的消费模式,以资源和能源的大量消费为支撑,追求近期目标和当代人消费的满足,鼓励畸形消费和过度消费,从而对环境和发展造成了极大的危害,已经成为当今世界环境问题不断恶化的主要原因.变革现行的传统消费模式,构建一种有利于可持续发展的环境友好型消费模式势在必行.构建环境友好型消费模式,要改变的是不可持续的消费观念;把文明、健康、科学的生活方式作为当前生活方式变革的基本方向;建立起完善的环境政策体系,从制度层面上为推进可持续消费发展提供重要保障;大力发展循环经济,激励消费者采取环境友好的消费方式.

    In this paper, we present Par@Graph, a software toolbox to reconstruct and analyze complex climate networks having a large number of nodes (up to at least 106) and edges (up to at least 1012). The key innovation is an efficient set of parallel software tools designed to leverage the inherited hybrid parallelism in distributed-memory clusters of multi-core machines. The performance of the toolbox is illustrated through networks derived from sea surface height (SSH) data of a global high-resolution ocean model. Less than 8 min are needed on 90 Intel Xeon E5-4650 processors to reconstruct a climate network including the preprocessing and the correlation of 3 × 105 SSH time series, resulting in a weighted graph with the same number of vertices and about 3.2 × 108 edges. In less than 14 min on 30 processors, the resulted graph's degree centrality, strength, connected components, eigenvector centrality, entropy and clustering coefficient metrics were obtained. These results indicate that a complete cycle to construct and analyze a large-scale climate network is available under 22 min Par@Graph therefore facilitates the application of climate network analysis on high-resolution observations and model results, by enabling fast network reconstruct from the calculation of statistical similarities between climate time series. It also enables network analysis at unprecedented scales on a variety of different sizes of input data sets.

    Full Text Available In contrast to the input perspective for evaluating planning metrics, this research takes the climatic environmental output effects as the starting point for assessing ecological city construction. Based on approaches such as observation data analysis, meteorological model simulation, and remote sensing, a set of climatic environmental performance assessment methods is developed and established. These methods mainly focus on surface ventilation assessment and urban thermal environment assessment. With the Yanqi Lake ecological development demonstration area located in Huairou district, Beijing as an example, the assessment of the local climatic environment before and after the construction are conducted, and relevant policy suggestions for urban planning and construction are presented. The results show that after development, the ventilation capacity will decrease overall and the ventilation potential index will decrease from 0.53 to 0.44. While this is not a large reduction, and is still at a favorable level, the ventilation potential in some local areas will markedly decrease. Furthermore, the thermal environment will become poorer to some extent; the urban heat island (UHI area and intensity will increase compared with the current situation; continuous heat islands may occur in local areas; the UHI potential index of the core area will rise from 0.0878 to 0.1217 (still a favorable level. Therefore, urban surfaces should be carefully developed and arranged during planning. It is suggested that the negative impacts of large areas of urban construction on the local climatic environment in the Yanqi Lake could be mitigated by 1 strengthening the airflow by introducing fresh, cold, northwesterly air via constructed ventilation corridors, 2 increasing the number of ecological cold sources, particularly for water bodies and green belts to prevent the UHI in the southern region of Yanqi Lake from becoming linked with each other, and 3 considering a

    Full Text Available Developing cities in India like Nagpur are growing exponentially in population due to industrialization. The ever increasing demand of the natural resources leads to depletion of limited resources and also affects local environment in terms of increasing pollution emissions especially carbon emission. With recourse to composite climatic condition (Nagpur, India the sustainable construction strategy is developed in the present paper. The developed strategy includes conservation of soil, energy, resources, material and water. It provides a systematic approach towards sustainability of building through quantification of energy consumption. Analysis of conventional and non-conventional material and technology on cost, energy consumption and carbon emission parameters helps in highlighting suitable options for sustainable construction. Strategy is validated through a case study of new construction of the residential buildings for enhanced environmental performance. The amount of excavated soil and its reutilization on site is taken into consideration. Locally available sustainable construction materials are compared for material cost, and embodied energy for selection of appropriate construction material. In order to conserve the ground water various options for the low flow devices, roof top rainwater harvesting and gray water recycling and reuse are suggested. Application of sustainable construction strategy to case study building revealed that 97% of natural soil is conserved through backfilling. Estimated carbon emission reduction due to recommended construction materials (sustainable bricks, cement, and steel with respect to conventional options is of the order of 60%. Recommended water conservation options resulted in 57% reduction in ground water demand.  However suggested sustainable construction strategy options estimated in increase in project cost by 13% whose effect can subsequently be reduced over the design life span computations.

    Technically speaking, building experts have the knowledge to deal with thermal inertia of buildings, solar gains, insulation, efficient ventilation, and daylighting... to get low energy buildings that provide comfort for the users. Buildings should always be designed according to the specificities of the local climate, according to a ''solar and bio-climatic construction'' approach. It is not always possible to fully apply these principles, particularly in urban areas with high density. However, this is unacceptable to keep building with such errors as insufficient insulation and direct electrical heating, single glazing, thermal bridges, low efficiency heating systems. This guide aims at encouraging the building experts to take into account the energy efficiency. Implementing a building energy label will allow general public to be aware of this issue and then, and will then lead to develop better practices. (author)

  5. Behavior of crushed rock aggregates used in road construction exposed to cold climate conditions

    2016-04-01

    Presently, about 90% of the aggregate production in Europe comes from naturally occurring resources: quarries and pits. Due to the increased demand for sand and gravel for construction purposes, not only in building but also in road construction, the last decade has seen a significant trend towards the use of more crushed rock aggregates. This resource has been more and more preferred to sand and gravel thanks to the significant technological development of its process and use phase. The performance of the aggregates is generally evaluated depending on three main factors: the geological origin (mineral composition, texture, structure, degree of weathering), the aggregate processing (crushing, sieving, washing, storing) and the user technology for a specific area of use (e.g. road construction, asphalt binders). Nevertheless climatic conditions should carefully be taken into account in application such as road construction. Large temperature gradients and high levels of humidity are known to significantly affect the performance of the material. Although the problem is, at least in the asphalt field, considered mostly from the binder point of view, this article aims to investigate the effect of aggregate properties on road performance in cold climatic conditions. Two different climatic areas will be taken into account: Norway and Spain. While both these countries are listed among the main European producers of aggregates, they represent significantly different climatic regions. While Norwegian weather is characterized by humid cold winters and relatively mild summers, Spain has temperate climate with cold regions in mountainous and internal areas. Both countries have been significantly affected by climate change with increasing temperature variations and instability. At the same time, similar winter maintenance measures, including the use of a considerable amount of solid and liquid chemicals to avoid ice formation (e.g. NaCl) and/or to provide better friction, are

  7. Influence of constructive characteristics of a room on the parameters of regulators of automated climatic systems

    Directory of Open Access Journals (Sweden)

    Samarin Oleg Dmitrievich

    Full Text Available Currently, the successful development of construction industry depends on the improved energy performance of buildings, structures and facilities, as well as on the quality assurance of the indoor climate. In view of the above, designing and operation of buildings should be aimed at the best (optimal solution of the following objective: to ensure the set-point values of indoor climate serviced by automated climate control systems, against the minimal energy consumption. In regard of its substantive structure, this paper describes the study on the relationship between the individual parameters of indoor thermal stability and the regulatory impact of automatic control systems (ACS. We analyzed the effect of structural room characteristics on the total energy consumption of the airflow processing unit in order to ensure energy saving. The final result is illustrated by numeric simulation with the use of a developed computer program and graphic examples. The proposed method is based on the assumption that the total thermal stability of the «room-ACVS-ACS» system is defined by heat absorption index of a room and the ACS control operation. This follows directly from the back-to-back connection of units corresponding to the room and ACVS in the scheme of automatic indoor climate control. Further study allowed authors to trace the influence of structural characteristics of a room on the total energy consumption needed for air intake treatment. This can be done by applying values of the main walling area. Basing on the developed algorithm, the authors made calculations using the computer program developed in Fortran. As a result a fragments of the program are presented - calculations of the parameters’ values included in the expressions and the total specific energy consumption for heating the air intake during the heating season, under varying room geometry, as well as the graphic illustration of the obtained relationships.

    social construction of climate change, not scientific claims, that are shaping decisions. While certainty is the common demand of those charged with making decisions concerning climate change, certainty is the quality that seems to be given least value in taking action. Weather records are all but ignored. The direct voice of scientists was heeded but not fully accepted. In the transition, the truth-to-power model appears to be somewhat modified, whereby power states that the future will be different, but the difference is determined by other sources; shaping images of risk and danger. One could not deny that climate and sea level have always been forces shaping patterns of human settlement. And one could not deny that perhaps the time is nigh to reassess the human relationship with nature. However, any measure considered should be done so with a rational sense of objectivity. To do otherwise, there is the risk of misallocating scare resources.

    2016-01-01

    Objectives This study aimed to evaluate the efficacy of a safety communication and recognition program (B-SAFE), designed to encourage improvement of physical working conditions and hazard reduction in construction. Methods A matched pair cluster randomized controlled trial was conducted on eight worksites (four received the B-SAFE intervention, four served as control sites) for approximately five months per site. Pre- and post-exposure worker surveys were collected at all sites (N=615, pre-exposure response rate of 74%, post-exposure response rate of 88%). Multi-level mixed-effect regression models evaluated the effect of B-SAFE on safety climate as assessed from surveys. Focus groups (N=6–8 workers/site) were conducted following data collection. Transcripts were coded and analyzed for thematic content using Atlas.ti (version 6). Results The mean safety climate score at intervention sites, as measured on a 0–50 point scale, increased 0.5 points (1%) between pre- and post-B-SAFE exposure, compared to control sites that decreased 0.8 points (1.6%). The intervention effect size was 1.64 (3.28%) (P-value=0.01) when adjusted for month the worker started on-site, total length of time on-site, as well as individual characteristics (trade, title, age, and race/ethnicity). At intervention sites, workers noted increased levels of safety awareness, communication, and teamwork compared to control sites. Conclusions B-SAFE led to many positive changes, including an improvement in safety climate, awareness, teambuilding, and communication. B-SAFE was a simple intervention that engaged workers through effective communication infrastructures and had a significant, positive effect on worksite safety. PMID:27158914

  10. The social construction of communication climate: An analysis of at-risk students in alternative high school

    Alternative high schools affect more potential high school dropouts than any other school or program and are designed to meet the needs of students who have had difficulty in conventional schools. This study examines the communication climate and constructions of caring in an alternative school for at-risk students by using a qualitative analysis grounded in the theoretical perspective of social constructionism. Observations and interviews were conducted over a six month time period. The first two chapters provide a review of literature and a detailed account of the methods used to conduct the study. Chapter Three describes the socially constructed nature of the school and the participants and the dialectical tensions of communication climate revealed from the analysis. The six dialectical tensions of communication climate are: (1) freedom/restraint, (2) disengagement/engagement, (3) personal communication/impersonal communication, (4) disconfirmation/confirmation, (5) equality/inequality, and (6) ambiguity/clarity. Although the school climate is comprised of each of these tensions, the data suggest that the interaction within the majority of classes created some common characteristics of the general communication climate at the school and can be characterized as one of freedom, disengagement, personal communication, disconfirmation, equality, and ambiguity. Chapter Four describes how caring was constructed and communicated. Although some students perceived some teachers as caring about students and about student learning, half of the students interviewed thought they were not learning or not learning much. Finally, Chapter Five provides a summary of the findings and a discussion of the results. The results of this study contribute to an understanding of the social construction of communication climate and caring in general, and within an alternative school for at-risk students, in specific. The results contribute to the understanding of the complexity of the

  12. Enhanced sensitivity of a mountain bog to climate change as a delayed effect of road construction

    Directory of Open Access Journals (Sweden)

    P. von Sengbusch

    2015-01-01

    Full Text Available Trees of Pinus rotundata (bog pine characterise many bogs in the mid-altitude mountains of central Europe (Switzerland, East and South Germany, Czech Republic. The research described here focuses on recent changes in the growth of bog pine on the Ennersbacher Moor, a mountain mire in the Black Forest (south-west Germany. An increase in the cover of bog pine is usually caused by drainage and subsequent drawdown of the water table. However, this bog has not been drained or directly disturbed in any other way. One possible explanation is that a road constructed in 1983 along one margin of the bog has diverted part of its water supply. Even though the road was designed to conduct potentially salt-contaminated drainage water away from the bog, its construction did not cause an immediate vegetation response in the 1980s and 1990s. Therefore, I hypothesise that it enhanced the sensitivity of the bog to climatic stress, predisposing it to a succession that was eventually triggered by a series of drought years in 2009–2011. Data collected near the centre of the bog over the period 1998–2014 indicate not only a distinct change in the relationship between height and trunk circumference of the trees, but also an increase of dwarf shrub cover and changes in the composition of Sphagnum communities. Although the pH of near-surface water may have increased slightly over this period, pH and EC values remain within typical ranges for raised bogs in the Black Forest. Examination of peat profiles reveals that the peat is more highly humified now than it was in 2002, and water table records from 2012–2014 show a greater amplitude of fluctuation than water table data collected in 1998–2001. Even though its mean level is only 105 mm below the ground surface, the water table is now observed to fall rapidly to depths of at least 350 mm during both wet and dry summers. Mapping surface (mesotopography and flow lines from the adjacent slope shows that the

As the students experienced the three lessons comprising the unit, data were taken of various modes, including pre-unit, mid-unit, post-unit, and delayed-post unit interviews, observer notes from the classroom, and artifacts created by the students as individuals and as members of a group. At the end of the unit, a written post-assessment was administered, and post-interviews were conducted with the selected students. These varied data sources were analyzed in order to develop themes corresponding to their frameworks of climate change. Negative cases were sought in order to test developing themes. Themes that emerged from the data were triangulated across the various data sources in order to ensure quality and rigor. These themes were then used to construct understandings of various students' frameworks of the content. Several findings emerged from this research. The first finding is that each student underwent some conceptual change regarding GCC, although of varying natures. The students' synthetic frameworks of GCC were more complex than their initial, or naive frameworks. Some characteristics of the naive frameworks included that the students tended to conflate climate change with a broader, generic category of environmental things. Examples of this conflation include the idea that climate change entails general pollution, litter, and needless killing of dolphins while fishing for tuna. This research suggests that students might benefit from explicit attention to this concept in terms of an ontological category, with the ideal synthetic view realizing that GCC is itself an example of an emergent process. Another characteristic of their naive frameworks includes some surprisingly accurate notions of GCC, including a general sense that temperatures and sea levels are rising. At the same time, none of the students were able to adequately invoke data to support their

    Informal learners interested in climate issues can find a wealth of information in the print and online media related to climate and climate change. Throughout these resources, the equal use of generic terms like 'global warming' and 'climate change' suggest a level of nuance in the science that is not easy to convey in this conventional media. Perhaps more than any other discipline, climate literacy has the most potential to be enhanced via the process of cognitive construction and reconstruction, rather than simple transmission of knowledge. Constructionism suggests that meaningful learning happens most effectively if the learner is actively engaged in constructing a product in the real world rather than absorbing information passively. Recent technological innovations have introduced mobile computing devices with sufficient power to do serious data analysis. The potential of these devices to augment climate literacy by turning citizens into scientists has yet to be exploited. We introduce ClimatePad, an iPad application that permits students and public to actively browse climate datasets, construct trends, plot time series, create composite differences and view animations of real-world climate data. Interactions with the ClimatePad permits varying the starting and ending dates of trends and differences. Climate analysis maps and animations can be customized with different color palettes, enticing the user to delve into and absorb the subtleties of the regional and temporal variations of the recent climate record. Finally, user-generated climate visualizations created with ClimatePad can be emailed to friends and shared via Facebook, entraining even more active learners.

    Decision makers and community leaders are key audiences to engage in our efforts to improve climate literacy. Climate Education Partners has been working with business leaders, elected officials, tribal leaders, and other Key Influentials in the San Diego Region to enhance the channels of communication outside traditional settings. Over the past year we have interviewed over 90 Key Influential San Diego leaders asking them about their knowledge of climate change and their personal and professional efforts to adapt to and/or mitigate the impacts of climate change. We also engaged them directly in the creation of an innovative educational resource called "San Diego, 2050 is Calling. How will we answer?" Results of the interviews indicate that 90% of these leaders are concerned about climate change, more than 50% are already doing something about the impacts, and the majority of them want more information, greater dialogue and examples of actions taken by other community leaders. We found that repeated engagement of leaders at the San Diego County Water Authority went from basic collaboration in our water tours, to greater participation of their top leaders in a water tour for top decision makers from the City of San Diego, finally culminating with full support of and participation in the 2050 report. The 2050 report represents an integrated approach blending local climate change science, social science education theory and presentation of a suite of solution-driven opportunities for local leaders. The report includes science infographics that illustrate rigorous scientific facts, statements from expert scientists and direct quotes from decision makers, and examples of successful climate change adaptation actions from companies, government groups and others. The video and photography sessions for the 2050 report led to many unexpected discussion among leaders with differing opinions on climate change, greater enthusiasm to participate in outreach activities with other

    As the publication shows, the public discussion in Germany is increasingly focusing on the cost of the promotion of renewable energy sources. Critical comments state that the EEG (Renewables Act) accounts for most of the recent electricity rate increases and also does not contribute to climate protection. This background paper of the Federal Environmental Office stresses the role of the EEC for climate protection and its effects on price trends in electricity supply. The resulting financial burden for the German citizens and industry is investigated, and it is discussed whether public funding of renewable energy sources is indeed beneficial for the German economy on the whole.

    International Nuclear Information System (INIS)

    Adaptation is a new policy area for the European Climate Change Policy. The Impacts and Adaptation Workgroup has been set up as part of European Climate Change Programme (ECCP II). The main objective of the workgroup is to explore options to improve Europe's resilience to climate change impacts, to encourage the integration of climate change adaptation into other policy areas at the European, national, regional and local level and to define the role of EU-wide policies complementing action by Member States. The aim of this initial programme of work is to identify good practice in the development of adaptation policy and foster learning from different sectoral experiences and explore a possible EU role in adaptation policies. The Commission has led a series of 10 sectoral meetings looking at adaptation issues for different sectors. One of these meetings looked at the impacts on urban planning and infrastructure in particular. This report summarises the state of play in the urban planning sector in relation to adaptation to climate change on the basis of the information gathered at the stakeholder meeting. Some of the other stakeholder meetings, such as the meeting on human health, have a strong connection with the urban planning agenda. Therefore, some actions in the sector report on adaptation and human health relate to urban planning and infrastructure considerations

  3. Indoor climate and moisture durability performances of houses with unvented attic roof constructions in a mixed-humid climate.

    A sealed or unvented attic is an energy-efficient envelope component that can reduce the amount of energy a house consumes for space conditioning if the air handler and/or ducts are located in the attic. The attic is typically sealed by using spray foam on the underside of the roof deck and covering the soffit, ridge and gable vents to minimize air leakage from the attic to the outside. This approach can save up to 10% in space-conditioning energy when ducts are located in the attic (DOE 2013). Past research done by ORNL and Florida Solar Energy Center suggests that in more hot, humid climates, an unvented attic could potentially create a more humid, uncomfortable living environment than a vented attic (Colon 2011, Boudreaux, Pallin et al. 2013). Research showed that controlling the higher indoor humidity could reduce the energy savings from the sealed, unvented attic, which in turn would decrease the energy savings payback. Research also showed that the roof assembly (5.5 inches of open-cell foam, 1inch of closed-cell foam, OSB, felt paper, and asphalt shingles) stored moisture, thus acting as a moisture buffer. During the fall and winter, the roof assembly stored moisture and during the spring and summer it released moisture. This phenomenon is not seen in a vented attic, in which the air exchange rate to the outside is greater and, in the winter, helps to dehumidify the attic air. It was also seen that in a vented attic, the direction of water vapor diffusion is on average from the attic to the interior of the house. Air leakage from the attic to the interior also occurs during more of the year in a house with an unvented attic than in one with a vented attic. These discoveries show that the moisture dynamics in a house with an unvented attic are much different from those in a house with a vented attic. This study reports on a series of computer model investigations completed to determine the key variables impacting indoor comfort and the durability of roof

  11. Simulation of the treatment performance of outdoor subsurface flow constructed wetlands in temperate climates

    International Nuclear Information System (INIS)

    Numerical models are a means to increase the understanding of the processes occurring in the 'black box' constructed wetland. Once reliable models for constructed wetlands are available they can be also used for evaluating and improving existing design criteria. The paper shows simulation results for outdoor experimental subsurface vertical flow constructed wetlands using CW2D, a multi-component reactive transport module developed to simulate transport and reactions of the organic matter, nitrogen and phosphorus in subsurface flow constructed wetlands. The surface area of the experimental vertical flow bed was 20 m2. The organic load applied was 27 g COD m-2 d-1 (corresponding to a specific surface area of 3 m2 per person). The aim of the work is to calibrate the model for temperature dependency that has been implemented in CW2D. Water temperature during the investigation period varied between 4 deg. C and 18 deg. C. The measured effluent concentrations during summer could be simulated using the standard CW2D parameter set when the flow model was calibrated well. However, the increasing effluent concentrations at low temperatures could not be simulated with the standard CW2D parameter set where temperature dependencies are considered only for maximum growth, decay, and hydrolysis rates. By introducing temperature dependencies for half-saturation constants for the hydrolysis and nitrification processes it was possible to simulate the observed behaviour. The work presented is a step on the way to validate the CW2D module. Model validation is a necessary step before numerical simulation can be finally used in practice, e.g. for checking existing design guidelines

    2015-03-01

    Full Text Available The continuous degradation of coral reef ecosystems on a global level, the disheartening expectations of a gloomy future for reefs’ statuses, the failure of traditional conservation acts to revive most of the degrading reefs and the understanding that it is unlikely that future reefs will return to historic conditions, all call for novel management approaches. Among the most effective approaches is the “gardening” concept of active reef restoration, centered, as in silviculture, on a two-step restoration process (nursery and transplantation. In the almost two decades that passed from its first presentation, the “gardening” tenet was tested in a number of coral reefs worldwide, revealing that it may reshape coral reef communities (and associated biota in such a way that novel reef ecosystems with novel functionalities that did not exist before are developed. Using the “gardening” approach as a climate change mediator, four novel ecosystem engineering management approaches are raised and discussed in this article. These include the take-home lessons approach, which considers the critical evaluation of reef restoration outcomes; the genetics approach; the use of coral nurseries as repositories for coral and reef species; and an approach that uses novel environmental engineering tactics. Two of these approaches (take-home lessons and using coral nurseries as repositories for reef dwelling organisms already consider the uncertainty and the gaps in our knowledge, and they are further supported by the genetic approach and by the use of novel environmental engineering tactics as augmenting auxiliaries. Employing these approaches (combined with other novel tactics will enhance the ability of coral reef organisms to adaptably respond to climate change.

    Troposphere is a transition layer between the troposphere and the stratosphere. The exchanges of air mass, water vapor, trace gas and energy between the troposphere and the stratosphere occur through this layer. Accurate and continuous observations of the tropopause on a global scale are crucial for monitoring stratosphere-troposphere exchange and understanding the balance of atmospheric tracers in the upper troposphere and lower stratosphere. In our work, we propose to measure tropopause by using GNSS Radio Occultation (RO) bending angles (BA) profiles. The proposed method fit with a dry model, namely Hopfield one, the BA profiles. Through the layers in which tropopause is contained, the residuals have an anomalous trend. The plot of residuals in this zone form a positive bump that we will try to exploit just to determine the relevant parameters of the tropopause. We will use the huge amount of data provides by the COSMIC mission for tuning the algorithms, perform a validation of the approach and compare our results with those achieved applying different techniques. The coordinates of a static Global Navigation Satellite System (GNSS) station placed on the ground are estimated together with the delay suffered by the incoming satellite signals through the atmosphere. The tropospheric delay (TD) is formulated as the product of the zenith delay (ZTD) with a mapping function depending on the sine of elevation angles. In processing chain, indeed, the ZTD is estimated together with the coordinates; while the MF is modelled apart, in an independent way, by using atmospheric profiles retrieved with balloon observations ( RAOB) as done for the Niell MF in 1996 or provided by climate or Numerical Weather Prediction (NWP) models as done for the Vienna MFs. In the present work we have reconstructed the MF by using atmospheric profiles given by GNSS radio occultation observations (GNSS-RO). We propose to use the mapping function built with GNSS RO and its evolution in time as

    Energy Technology Data Exchange (ETDEWEB)

    Greitzer, Frank L.; Carroll, Thomas E.; Roberts, Adam D.

    2011-09-01

    Cyber friendly fire (FF) is a new concept that has been brought to the attention of Department of Defense (DoD) stakeholders through two workshops that were planned and conducted by the Air Force Research Laboratory (AFRL) and research conducted for AFRL by the Pacific Northwest National Laboratory. With this previous work in mind, we offer a definition of cyber FF as intentional offensive or defensive cyber/electronic actions intended to protect cyber systems against enemy forces or to attack enemy cyber systems, which unintentionally harms the mission effectiveness of friendly or neutral forces. Just as with combat friendly fire, a fundamental need in avoiding cyber FF is to maintain situation awareness (SA). We suggest that cyber SA concerns knowledge of a system's topology (connectedness and relationships of the nodes in a system), and critical knowledge elements such as the characteristics and vulnerabilities of the components that comprise the system (and that populate the nodes), the nature of the activities or work performed, and the available defensive (and offensive) countermeasures that may be applied to thwart network attacks. A training implication is to raise awareness and understanding of these critical knowledge units; an approach to decision aids and/or visualizations is to focus on supporting these critical knowledge units. To study cyber FF, we developed an unclassified security test range comprising a combination of virtual and physical devices that present a closed network for testing, simulation, and evaluation. This network offers services found on a production network without the associated costs of a real production network. Containing enough detail to appear realistic, this virtual and physical environment can be customized to represent different configurations. For our purposes, the test range was configured to appear as an Internet-connected Managed Service Provider (MSP) offering specialized web applications to the general public

    2015-01-01

    This study examines the degree to which construction sector employees perceive that safety is important in their organizations/sites and how job satisfaction affects these perceptions when age is introduced as a moderator variable. Two-way analysis of variance demonstrated that job satisfaction has a strong effect on perceived management commitment to work safety and that this relationship was moderated by respondents' age. Job satisfaction was associated with perceived accident rate and safety inspection frequency, but the proposed role of age in this linkage was not confirmed. Consequently, the findings indicated that by increasing the level of job satisfaction, perceptions of these safety climate aspects proved to be more positive. The conclusion is that these relationships could further lead to a lower percentage of accidents and injuries in the workplace and better health among employees. A significant relationship between job satisfaction, age and perceived co-workers' commitment to work safety was not found. PMID:26693996

    While the International Energy Conservation Code 2012 (IECC 2012) has been adopted at a national level, only two cold climate states have adopted it as their new home energy code. Understanding the resistance to adoption is important in assisting more states accept the code and engage deep energy strategies nationwide. This three-part assessment by the NorthernSTAR Building America Partnership was focused on foundation insulation R-values for cold climates and the design, construction, and performance implications. In Part 1 a literature review and attendance at stakeholder meetings held in Minnesota were used to assess general stakeholder interest and concerns regarding proposed code changes. Part 2 includes drawings of robust foundation insulation systems that were presented at one Minnesota stakeholder meeting to address critical issues and concerns for adopting best practice strategies. In Part 3 a sampling of builders participated in a telephone interview to gain baseline knowledge on insulation systems used to meet the current energy code and how the same builders propose to meet the new proposed code.

    The complex network framework has been successfully applied to the analysis of climatological data, providing, for example, a better understanding of the mechanisms underlying reduced predictability during El Ni\\~no or La Ni\\~na years. Despite the large interest that climate networks have attracted, several issues remain to be investigated. Here we focus in the influence of the periodic solar forcing in climate networks constructed via similarities of monthly averaged surface air temperature (SAT) anomalies. We shift the time series in each pair of nodes such as to superpose their seasonal cycles. In this way, when two nodes are located in different hemispheres we are able to quantify the similarity of SAT anomalies during the winters and during the summers. We find that data time-shifting does not significantly modify the network area weighted connectivity (AWC), which is the fraction of the total area of the Earth to which each node is con- nected. This unexpected network property can be understood in terms...

  6. Mobility and climate: Avenues to a climate-friendly transport policy. Second report by the Inquiry-Commission 'Protection of the Earth Atmosphere' of the 12th German Bundestag

    International Nuclear Information System (INIS)

    In Germany, the transport sector currently accounts for some 20 per cent of greenhouse-relevant trace gas emissions. According to all forecasts it is the sector with the highest growth dynamics both nationally and at the European level. Because of the internal European market and the opening of the frontiers to eastern Europe, the Federal Republic of Germany has become a turntable of international transport. The report points out what causes traffic, makes projections of the development to be expected, and indicates the potentials for cutting down greenhouse gas emissions. The following options are open: traffic avoidance, translocation of traffic, technical optimization of the means of transport, and optimized organization of the transport system. The Commission holds that a cut of some 25 per cent in greenhouse gas emissions as is required to curb the greenhouse effect is possible provided its policy recommendations are executed without restrictions. This presupposes, however, that all - from the European Union over the Federal German government to the laender and communities and including also industry and each individual citizen - must contribute towards making traffic more environmentally friendly. Loss of mobility is not an inevitable result. (orig.)

    Full Text Available Objective – To explore whether academic institutions that score highly on the LGBT Friendly Campus Climate Index also have well-developed Web-based library resources to support GLBT (gay, lesbian, bisexual, transgender students.Design – Website analysis, percentage, and binary logistic regression analysis.Setting – Library websites of colleges and universities in four American geographic regions: Northeast, Midwest, South, and West.Subjects – There were 259 colleges and universities that participated in the 2010 LGBT-Friendly Campus Climate Index.Methods – The author visited the library websites of all institutions and surveyed available GLBT-related resources. The criteria for online resources included: 1 A research guide for GLBT studies or geared toward GLBT students, 2 An individual identified within the research guide as a contact for GLBT-related resources, and 3 A subscription to EBSCO’s GLBT Life database. Whether or not the academic libraries had the above resources was then analyzed with each institution’s score on the climate survey scale. The author controlled for geographical location, religious affiliation, and campus setting of the college or university.Main Results – There is a positive direct relationship between whether a library makes GLBT resources available on the Web and campus climate. However, only 25% of libraries surveyed published a research guide, 18% named a contact individual, and 31% subscribed to GLBT Life.Conclusion – While parent institutions commit to GLBT students by taking the LBGT-Friendly Campus Climate Index survey, academic libraries lag behind providing online resources for this community.

    Nowadays climate change is one of the environmental problems in the global policy agenda. However, in countries like United States and United Kingdom the media started to report regularly on this issue in 1988. Since then many researches have been carrying out focused on how the media influence, along with other factors, public understanding of climate change through the media construction of the problem in several countries. Given the implications of social acceptance for design and implementation of public policies on mitigation and adaptation to climate change, the overall aim of this report is to review the status of the issue from a qualitative and quantitative approach. Qualitatively, media construction of climate change is described as the result of different processes taking place at macro and micro scales. Interactions among scientists, politicians, industry, the media themselves and the social context are considered macro-scale influences, while journalistic values and norms shape the media coverage of this environmental problem at micro-scale when media professionals report on climate change. From a quantitative point of view this paper also includes the evolution of newspaper coverage on climate change in Spain from 1996 to 2006 and these figures are compared to the results obtained in the United States and United Kingdom during the same period.

    Three constructed wetlands (CWs), two located in southern and one in central Finland, were monitored during 2013-2015. The southern CWs Hovi (0.6 ha wet area) and Rantamo-Seitteli (24 ha wet area) were monitored continuously by s::can nitro::lyser (www.s-can.at) sensors. On average 10 pairs (inflow and outflow) of water samples were annually taken in the two southern CWs and 20 pairs in the northernmost Tarvaala CW (wet area 1.4 ha). In Tarvaala, a portable, continuously measuring Micromac 1000 -phosphate analyzer (www.systea.it) was also tested at the CW outlet in 2015. The CWs differed in their size, dimensioning (CW-to-catchment area ratio) and in the characteristics of their upstream catchments. The Hovi CW has 5.0% CW-to-catchment area ratio and 100% agricultural land use in its clayey catchment. The corresponding percentages were for the Rantamo-Seitteli CW (clayey catchment) 1.3% and 42%, and for the Tarvaala CW (coarse soil type in the catchment) 1.0% and 16%. The average annual total suspended solids (TSS) retentions in Hovi, Rantamo-Seitteli and Tarvaala CWs were 79%, 6% and 50%, respectively. The average annual total phosphorus (TP) retentions were 61% at Hovi, 22% at Rantamo-Seitteli and 23% at Tarvaala. The unexpectedly high TSS and TP retentions at Tarvaala were probably due to the coarse soil type with more readily settling particles than in two other CWs. In Hovi and Rantamo-Seitteli CWs also dissolved reactive phosphorus (DRP) was measured. The DRP retentions (83% at Hovi and 27% at Rantamo-Seitteli) were higher than those of TP, which was probably due to the high contents of P-binding Al- and Fe-oxides in the soil of these two CWs. In the Hovi CW, vivid biological activity (abundant vegetation, algae and microbes) might also have played a role. The average annual total nitrogen (TN) retentions in Hovi and Rantamo-Seitteli CWs were 66% and 14%, respectively. At Tarvaala, TN retention varied annually so that no net retention over the whole period

  12. A fast algorithm for identifying Friends-of-Friends halos

    2016-01-01

    We describe a simple and fast algorithm for identifying friends-of-friends clusters and prove its correctness. The algorithm avoids unnecessary expensive neighbor queries, uses minimal memory overhead, and rejects slowdown in high over-density regions. We define our algorithm formally based on pair enumeration, a problem that has been heavily studied in fast 2-point correlation codes and our reference implementation employs a dual KD-tree correlation function code. We construct halos in a hierarchical merger tree, and use a splay operation to reduce the average cost of identifying the root of a cluster from $O[\\log L]$ to $O[1]$ ($L$ is the size of a cluster) without additional memory costs. This reduces the overall time complexity of merging trees form $O[L\\log L]$ to $O[L]$, reducing the number of operations per by orders of magnitude. We next introduce a pruning operation that skips pair enumeration between two fully self-connected KD-tree nodes. This improves the robustness of the algorithm, reducing cost...

    Climate change impacts on water resources, particularly groundwater, is a highly debated topic worldwide, triggering international attention and interest from both researchers and policy makers due to its relevant link with European water policy directives (e.g. 2000/60/EC and 2007/118/EC) and related environmental objectives. The understanding of long-term impacts of climate variability and change is therefore a key challenge in order to address effective protection measures and to implement sustainable management of water resources. This paper presents the modeling approach adopted within the Life + project TRUST (Tool for Regional-scale assessment of groUndwater Storage improvement in adaptation to climaTe change) in order to provide climate change hazard scenarios for the shallow groundwater of high Veneto and Friuli Plain, Northern Italy. Given the aim to evaluate potential impacts on water quantity and quality (e.g. groundwater level variation, decrease of water availability for irrigation, variations of nitrate infiltration processes), the modeling approach integrated an ensemble of climate, hydrologic and hydrogeologic models running from the global to the regional scale. Global and regional climate models and downscaling techniques were used to make climate simulations for the reference period 1961-1990 and the projection period 2010-2100. The simulation of the recent climate was performed using observed radiative forcings, whereas the projections have been done prescribing the radiative forcings according to the IPCC A1B emission scenario. The climate simulations and the downscaling, then, provided the precipitation, temperatures and evapo-transpiration fields used for the impact analysis. Based on downscaled climate projections, 3 reference scenarios for the period 2071-2100 (i.e. the driest, the wettest and the mild year) were selected and used to run a regional geomorphoclimatic and hydrogeological model.

    Peer relationships, particularly friendships, have been theorized to contribute to how children and adolescents think about social and moral issues. The current study examined how young adolescent best friends (191 dyads; 53.4% female) reason together about multifaceted social dilemmas and how their reasoning is related to friendship quality. Mutually-recognized friendship dyads were videotaped discussing dilemmas entailing moral, social-conventional and prudential/pragmatic issues. Both dyad members completed a self-report measure of friendship quality. Dyadic data analyses guided by the Actor-Partner Interdependence Model indicated that adolescent and friend reports of friendship qualities were related to the forms of reasoning used during discussion. Friends who both reported that they could resolve conflicts in a constructive way were more likely to use moral reasoning than friends who reported that their conflict resolution was poor or disagreed on the quality of their conflict resolution. The findings provide evidence for the important role that friendship interaction may play in adolescents' social and moral development. PMID:23666555

  12. Systematic Review of Methods in Low-Consensus Fields: Supporting Commensuration through `Construct-Centered Methods Aggregation’ in the Case of Climate Change Vulnerability Research

    Science.gov (United States)

    Crane, Todd A.; Chesterman, Sabrina

    2016-01-01

    There is increasing interest in using systematic review to synthesize evidence on the social and environmental effects of and adaptations to climate change. Use of systematic review for evidence in this field is complicated by the heterogeneity of methods used and by uneven reporting. In order to facilitate synthesis of results and design of subsequent research a method, construct-centered methods aggregation, was designed to 1) provide a transparent, valid and reliable description of research methods, 2) support comparability of primary studies and 3) contribute to a shared empirical basis for improving research practice. Rather than taking research reports at face value, research designs are reviewed through inductive analysis. This involves bottom-up identification of constructs, definitions and operationalizations; assessment of concepts’ commensurability through comparison of definitions; identification of theoretical frameworks through patterns of construct use; and integration of transparently reported and valid operationalizations into ideal-type research frameworks. Through the integration of reliable bottom-up inductive coding from operationalizations and top-down coding driven from stated theory with expert interpretation, construct-centered methods aggregation enabled both resolution of heterogeneity within identically named constructs and merging of differently labeled but identical constructs. These two processes allowed transparent, rigorous and contextually sensitive synthesis of the research presented in an uneven set of reports undertaken in a heterogenous field. If adopted more broadly, construct-centered methods aggregation may contribute to the emergence of a valid, empirically-grounded description of methods used in primary research. These descriptions may function as a set of expectations that improves the transparency of reporting and as an evolving comprehensive framework that supports both interpretation of existing and design of future

  13. Local Constructions of Vulnerability and Resilience in the Context of Climate Change. A Comparison of Lübeck and Rostock

    Full Text Available Climate change is globally defined as a “reality”. This does not mean however that the way in which it is understood is the same all over the world. Rather, perceptions may differ at different places and times, even if physical and geographical conditions are similar. For the time being, this phenomenon has not been dealt with on a theoretical-conceptual level. The article will address this desiderate. Based on the approaches of social constructivism as well as actor-network theory, a theoretical concept will be suggested as a heuristic model for empirical analysis. By the examples of Lübeck and Rostock, two cities on Germany’s Baltic coast, it will be shown that climate change related perceptions of vulnerability and resilience may build on physical-material aspects but that they are above all considerably interwoven with specific cultural and social patterns of interpretation. In the framework of the local discourse in Lübeck, it is the strong Hanseatic tradition which consumes the climate change issue, whereas in Rostock it is the problems and historical breaks of a transformation society which shape the way of viewing climate change.

    Greenhouse gas emissions from building linked today to a large extent to the energy consumption during the operating period. Through increasingly stringent energy requirements and other changes, the energy consumption for the operation could go down over time. This means in this case that the energy required to produce, transport and set up the building, to a greater extent can be relatively more important in a life-cycle analysis. KRD in that regard ha given Oestfoldforskning the commission to conduct a literature study that will provide an overview and assessment of the literature / research papers describing various building materials climate impact and how this translates into a lifetime (LCA - Life Cycle Assessment), and thus describe the knowledge platform these analyzes are based in. It also means a description of the factors that affect the climate and the environment, including the stages of life that are important. Literature study is conducted by searching scientific databases (Springer Link, Science Direct, Google Scholar, Norwegian EPD database of declarations). The literature search is limited to studies that are based on LCA as a methodology for calculating the climate impacts associated with the construction and building materials. Based on the review of literature is also undertaken an analysis focusing on explaining the methodological platform between the studies are based on, in order to explain why the results differ and / or may not be comparable.(eb)

  17. Theoretical Construction and Empirical Research on A Preschooler-friendly Implicit Association Test%幼儿友好型内隐联想测验的建构及有效性

    The Implicit Association Test (IAT) is widely used in the research examining adults’ biases. The IAT measures differential association of two target concepts with an attribute, typically as a means to examine the extent to which social categories have positive or negative associations. One limitation of this method is that it has high executive function demands and is consequently not appropriate for use with young children. In the present research we address this limitation by developing a version of the task that can be used during the preschool years, which we refer to as the Preschooler-friendly IAT (PSF-IAT). In Study 1, we validated the effectiveness of the PSF-IAT in a non-social domain, by using it to detect presumed near-universal evaluative association involving the contrasts of flowers versus insects. In Study 2, we validated the effectiveness of the PSF-IAT in a social domain, by using it to document yound Chinese children’s racial bias against Africans, and show that the assessment of this bias was correlated with another implicit assessment.%本研究依据经典IAT (Implicit Association Test)的核心原理构建了幼儿友好型内隐联想测验(Preschooler-friendly Implicit Association Test, PSF-IAT)。它由两部分联结任务组成,以反应时为指标,通过对概念刺激和属性刺激之间自动化联系的评估进而对幼儿的内隐态度进行间接测量。本研究采用两种方式对PSF-IAT范式的适用性进行验证:首先,将PSF-IAT用于测试幼儿对花和虫的态度,检验该范式在非社会范畴概念态度研究中的可行性;其次,将PSF-IAT用于测试幼儿内隐种族态度,并验证其与另一种幼儿内隐态度测试方法间结果的相关性,检验该范式在社会范畴概念态度研究中的可行性。研究结果表明, PSF-IAT符合学前儿童认知发展与行为反应的特点,能有效测量幼儿的内隐态度。

  18. Friendly units for coldness

    2006-01-01

    Measures of temperature that center around human experience get lots of use. Of course thermal physics insights of the last century have shown that reciprocal temperature (1/kT) has applications that temperature addresses less well. In addition to taking on negative absolute values under population inversion (e.g. of magnetic spins), bits and bytes turn 1/kT into an informatic measure of the thermal ambient for developing correlations within any complex system. We show here that, in the human-friendly units of bytes and food Calories, water freezes when 1/kT ~200 ZB/Cal or kT ~5 Cal/YB. Casting familiar benchmarks into these terms shows that habitable human space requires coldness values (part of the time, at least) between 0 and 40 ZB/Cal with respect body temperature ~100 degrees F, a range in kT of ~1 Cal/YB. Insight into these physical quantities underlying thermal equilibration may prove useful for budding scientists, as well as the general public, in years ahead.

    With the huge intensification of agriculture and the increasing awareness to human health and natural resources sustainability, there was a shift towards the development of environmental friendly N application approaches that support sustainable use of land and sustain food production.The effectiveness of such approaches depends on their ability to synchronize plant nitrogen demand with its supply and the ability to apply favored compositions and dosages of N-species.They are also influenced by farming scale and its sophistication, and include the following key concepts: (i) Improved application modes such as split or localized ("depot") application; (ii) use of bio-amendments like nitrification and urease inhibitors and combinations of (i) and (ii); (iii) use of controlled and slow release fertilizers; (iv) Fertigation-fertilization via irrigation systems including fully automated and controlled systems; and (v) precision fertilization in large scale farming systems. The paper describes the approaches and their action mechanisms and examines their agronomic and environmental significance. The relevance of the approaches for different farming scales, levels of agronomic intensification and agro-technical sophistication is examined as well.

  1. Construction of a SORCE-based Solar Spectral Irradiance (SSI) Record for Input into Chemistry Climate Models

    Science.gov (United States)

    Harder, J. W.; Fontenla, J. M.

    2015-12-01

    We present a research program to produce a solar spectral irradiance (SSI) record suitable for whole atmosphere chemistry-climate model (CCM) transient studies over the 2001-2015 time period for Solar Cycle 23 and 24 (SC23-24). Climate simulations during this time period are particularly valuable because SC23-24 represents the best-observed solar cycle in history - both from the perspective of solar physics and in terms of Earth observation systems. This record will be based predominantly on the observed irradiance of the SORCE mission as measured by the SIM and SOLSTICE instruments from April of 2003 to the present time. The SSI data record for this proposed study requires very broad wavelength coverage (115-100000 nm), daily spectral coverage, compliance of the integrated SSI record with the TSI, and well-defined and documented uncertainty estimates. While the majority of the record will be derived from SORCE observations, extensions back to the SC23 maximum time period (early 2001) and closure of critical gaps in the SORCE record will be generated employing the Fontenla et al. (2015) Solar Radiation Physical Model (SRPMv2). Since SRPM is a physics-based model, estimates of the SSI for wavelengths outside the SORCE measurement range can be meaningfully included. This model now includes non-LTE contributions from metals in the atomic number range 22-28 (i.e. titanium through nickel) as well as important molecular photo-disassociation contributions from molecules such as NH, molecular hydrogen, CH, and OH led have led to greatly improved agreement between the model and the observed 0.1 nm SOLSTICE spectrum. Thus comparative studies of the SORCE observations with SRPMv2 provide meaningful insight into the nature of solar variability critical for subsequent Earth atmospheric modeling efforts.

  2. Merging Active and Passive Microwave Soil Moisture Data to Construct Long-Term Time Series in Support of Climate Studies

    In the framework of the Water Cycle Multi-mission Observation Strategy (WACMOS) project funded by ESA, a first multi-decadal (30+ years) global soil moisture record will be generated by merging data sets from various active and passive microwave sensors. Combining multiple data sets can bring many advantages in terms of enhanced temporal and spatial coverage and temporal resolution. Nevertheless, to benefit from this strategy, error budgets of the individual data sets have to be well characterized, and strategies need to be developed for adequately merging data sets that underlie different retrieval methods, cover different time spans and represent soil moisture over different depth intervals. This study shows a new methodology for merging soil moisture products from the ERS and ASCAT scatterometers with AMSR-E, TRMM and SSM/I radiometer-based soil moisture data. First, using GLDAS-NOAH modeled soil moisture data as an independent reference, we characterized the error structures of the different data sets by triple collocation. Then, we used the cumulative distribution function matching technique to overcome systematic differences related to differences in frequency and retrieval approaches. Finally, the error structures and correlations between the different data sets were used to design an adequate merging scheme. First results show that the merged product brings improvements with respect to the single-sensor products in terms of spatial and temporal coverage. Besides, in areas where active and passive sensors perform equally well, the number of observations can be significantly increased. We expect that the final merged product will enhance our understanding on the impacts of climate on terrestrial hydrology and provide a sound basis to ESA's Climate Change Initiative.

  3. Critical friends: A way to develop preceptor competence?

    Science.gov (United States)

    Carlson, Elisabeth

    2015-11-01

    Preceptorship entails for nurses to create a supportive learning and working climate where students or newcomers are given opportunities to develop professional competence. However, being a skilled and experienced nurse does not automatically turn the professional into a skilled educator as teaching of a subject is a whole different story. Preceptors need to continuously and critically reflect on their practices in order to facilitate the development of professional pedagogical competence. Critical friends are colleagues with comparable educational background evaluating the work of each other. The relationship should rely on friendship and mutual trust, adding new dimensions to the reflective process. Being engaged in a critical friendship allows the "friends" to become aware of their own shortcomings which can then be reflected on in relation to clinical as well as pedagogical practices. Being and having a critical friend might be one promising way forward for preceptors to develop pedagogical and professional competence. PMID:25498362

    2016-03-01

    Full Text Available This paper presents the results of an experimental study that was conducted in 15 office buildings in the humid and cold tropics during the working hours of the dry and rainy seasons in Cameroon. This was with the aim to study the effects that local and imported materials had on indoor air quality. To achieve this objective, the adaptive model approach has been selected. In accordance with the conditions of this model, all workers were kept in natural ventilation and, in accordance with the general procedure, a questionnaire was distributed to them, while variables, like air temperature, wind speed, and relative humidity were sampled. The results showed a clear agreement between expected behaviour, in accordance with the characteristics of building construction, and its real indoor ambience once they were statistically analysed. On the other hand, old buildings showed a higher percentage of relative humidity and a lower degree of indoor air temperature. Despite this, local thermal comfort indices and questionnaires showed adequate indoor ambience in each group of buildings, except when marble was used for external tiling. The effect of marble as an external coating helps to improve indoor ambience during the dry season. This is due to more indoor air and relative humidity being accumulated. At the same time, these ambiences are degraded when relative humidity is higher. Finally, these results should be taken cognisance of by architects and building designers in order to improve indoor environment, and overcome thermal discomfort in the Saharan area.

    2005-09-01

    The aim of this study was to examine the relationship between the perceived motivational climate, achievement goals, perfectionism and indices of peer relationships in a sample of young male and female Norwegian soccer players. The sample consisted of 1719 experienced soccer players (1231 males, 488 females) aged 12-19 years (mean = 14.9 years) participating in the Norway Cup international youth soccer competition. The players responded to a questionnaire measuring perceived peer acceptance and quality of friendship in soccer, perceived motivational climate, achievement goals and perfectionism in soccer. Canonical correlation analyses revealed that young female players who perceived the motivational climate as predominantly mastery oriented, and who were moderately task oriented and scored negatively on maladaptive perfectionism, reported better relations with their peers in soccer. Constructive peer relations were evident in that they scored positively on companionship with their best friend in soccer; they perceived this friend as being loyal and allowing of free discussion, and they reported being socially accepted by their peers in soccer. Mirroring these findings, young male players who perceived the motivational climate as predominantly performance oriented, who had a moderately negative score on task orientation but a quite strong positive score on maladaptive perfectionism, reported negative relationships with peers in terms of these aspects. They also reported being in conflict with their best soccer friend. The findings suggest that the qualities of motivation have a systematic relationship with peer acceptance and the quality of friendship in male and female youth soccer. PMID:16195049

    2016-07-01

    Sociologists of education have long been interested in the effects of peer relations on educational outcomes. Recent theory and research on adolescence suggest that peers on the boundaries of students' friendship networks may play an important role in shaping behaviors and educational outcomes. In this study, we examine the importance of a key "intermediate peer context" for students' outcomes: the friends of a student's friends. Our findings indicate both friends' and friends' friends' characteristics independently predict students' college expectations and their risk of dropping out of high school (although only friends' characteristics predict GPA). Our models suggest the magnitude of students' friends-of-friends' characteristics are at least as large their friends' characteristics. Together, the association between the peer context and students outcomes is considerably larger when accounting for both the characteristics of students' friends and the friends of their friends.

    The performance of six multistage hybrid constructed wetland systems was evaluated. The systems were designed to treat four kinds of high-content wastewater: dairy wastewater (three systems, average inflow content 2,400-5,000 mg·COD l(-1), 3-6 years of operation); pig farm wastewater, including liquid food washing wastewater (one system, 9,500 mg·COD l(-1), 3 years); potato starch processing wastewater (one system, 20,000-60,000 mg·COD l(-1), 3 years); and wastewater containing pig farm swine urine (one system, 6,600 mg·COD l(-1), 2.8 years) (COD = chemical oxygen demand). The systems contained three or four vertical (V) flow beds with self-priming siphons and surface partitions and no or one horizontal (H) flow bed (three to five beds). In some V flow beds, treated effluents were recirculated (Vr) through the inlet to improve performance. Mean annual temperature was 5-8 °C at all locations. To overcome clogging due to the high load in a cold climate, we applied a safety bypass structure and floating cover material to the V flow beds. Calculated average oxygen transfer rates (OTRs) increased proportionally with the influent load, and the OTR value was Vr > V> H. The relations of load-OTR, COD-ammonium, and a Arrhenius temperature-dependent equation enable the basic design of a reed bed system. PMID:24135094

    together. Qualitative data which were collected discussions saved and analyzed with method of content analysis. At the end of analysis, an outline form consisting of friend pressure determines scale via student’s expressions about friends pressure. Outline form is brought out and revised. Finally 35 items are determined. These items are examined by 5 experts from academic field and problematic, inadequate and out of scope questions are removed from the final form. At the end 11 questions remained and 24 items- the friend pressure determining scale is created. In addition, scale is examined for suitability of Turkish language. The item levels of five-point, Likert type scale, are determined as 1. Never, 2. Rarely, 3.Sometimes, 4.Often, 5.Always. For each item of the scale, item-total correlations are examined. After analysis, it is seen that item-total correlation coefficients of the scale changes between 0.608 and 0.322. In order to demonstrate construction validity of the scale factor analysis is conducted. Accordingly, KMO value 0.906 and Barlett test value 3397,158 (p=0,000 level of significance were calculated. After the determining of suitability of factor analysis, basic components (exploratory factor analysis is applied. It is seen that the factor analysis, the common factor variance of the items is between 0,413-0,696 and the items are located under six sub factor which eigenvalues greater than one. Also, it is seen that the eigenvalues of factors are 7.262, 1.731, 1.322, 1.188, 1.066, 1.023 and first factor describes 30,258% of the total variance. According to these results, it is concluded that the scale has a single factor. Therefore, analysis is repeated according to single factor. After analysis, it is seen that values of load factor changes between 0.365 and 0.659. For determining single factor structure, confirmatory factor analysis (CFA is conducted. In the last stage, internal consistency is examined and separated into two equivalent groups. According to

    2012-01-01

    In responding to global climate change, the idea of low-carbon economy emerges as the times require. Developing low - carbon economy is based on the construction of low-carbon society. The so called "two-orientation society" (resources con- servation orientated society and environmental friendly orientated society) is the concrete representation of low-carbon society with Chinese characteristics, and an actual action for China in develop- ing low-carbon economy. Based on urban agglomeration, the paper discusses the meaning of and the route to low-carbon society which would better reflect the intrinsic requirements of such a society.

    Energy Technology Data Exchange (ETDEWEB)

    Pellischek, G. [MTU, Engine Industry (Country unknown/Code not available)

    1998-03-01

    The Thematic Network on the `Efficient and Environmentally Friendly Aero-engine` integrates the various research projects of the European aero-engine industry conducted under the European Commission Fourth Framework Programme in order to emphasize the targeted character of the research work, to encourage mutual exchange of information between related research areas and to improve the strategic co-ordination at a European level. By introducing specific clusters on Turbomachinery Design Tools, Advanced Materials and Low Emission Combustor Technologies the majority of essential engine projects will be covered and thus enable a broadly based cross-flow of information between newly emerging projects from the latest call for proposals and those already active following the launch of the current Framework Programme. Research projects on engine noise will be included in the aircraft noise cluster `X-Noise`, which will maintain informal links with the aero-engine TRA (Targeted Research Action). The relation with the AERONET-TRA and more fundamental climate research will be maintained via the cluster on the Low Emission Combustor Technologies. Strategic cluster and TRA meetings of all parties concerned will serve as the mechanism for information exchange inside the engine family and also with the European Commission and, where appropriate, the public. The aero-engine TRA will be co-ordinated by MTU, who currently hold the chair of the Engine Industry Management Group (EIMG) with strong support from a steering committee incorporating the other EIMG representatives.

    Social norms are thought to be a strong influence over eating, but this hypothesis has only been experimentally tested with groups of strangers, and correlational studies using actual friends lack important controls. We manipulate an eating norm in the laboratory and explore its influence within established friendships. In two studies we randomly assigned groups of three friends to a restrictive norm condition, in which two of the friends were secretly instructed to restrict their intake of a...

  11. Friends of the Earth and the Nirex Inquiry

    International Nuclear Information System (INIS)

    The case presented by Friends of the Earth against the proposed construction by UK Nirex Ltd of an underground Rock Characterisation Facility (RCF) at a site in the Sellafield area is summarised. The RCF is part of an investigation by Nirex into a suitable site for an underground repository for the disposal of radioactive waste. The objections were raised at a Planning Inquiry in 1995. Expert witnesses called by Friends of the Earth considered the adequacy of the geological characterisation and baseline monitoring work carried out by Nirex, and natural and induced changes to the geological barrier which may be associated with geological, engineering and chemical phenomena. Their conclusions are briefly set out here and their detailed evidence presented to the Inquiry in other papers. The overall conclusion reached by Friends of the Earth on the basis of this evidence is that Nirex has not undertaken sufficient preparatory work to support their claim that the RCF would provide key information to enable a final decision to be made on the suitability of the Sellafield site for a radioactive waste repository. Furthermore, the RCF would in itself serve to make the necessary data impossible to obtain. The proposal for the construction of the RCF should therefore be rejected. (UK)

  16. Development of environmentally friendly briquettes

    International Nuclear Information System (INIS)

    The DMT has developed an industrial briquette consisting of about 87% hardcoal, 7% molasses pulp and 6% hydration limestone which meets the requirements of the clean air authority as an environmentally friendly fuel for travelling grate boilers. In extensive tests in a 4.4 MW travelling grate boiler these briquettes with molasses and limestone additives proved to be particularly effective in terms of reducing sulphur dioxide emission in the flue gas. They exhibited good ignition and combustion behaviour as well as a considerable reduction in nitrogen oxide emission. In a large-scale test with 1000 t of briquettes in a 46.5 MW travelling grate furnace it proved possible to confirm the good combustion behaviour and the reduced emission of sulphur oxide and nitrogen oxide in the flue gas.

    The investigation of B village in Hubei province have found some problems as follows: at the regional level, the socialized elderly supports are underdeveloped; at the community level, the infrastructure is insufifcient;at the organizational level, rural community organization in the elderly care exists"illiteracy"phenomenon;at the family level, the function of family caring for the old people have been weaken;and at the individual level, there is a negative self-cognition and heavy manual labor Etc. The reason for the rural elderly care becoming problem is closely related to the urbanization. The community oriented social work practice model should be introduced into the rural elderly care system. Through the integration of social work intervention techniques and comprehensive use of case work, group work and community work and other methods, social work tries to promote the construction of rural old age friendly community from two dimensions of physical environment and human environment.%通过对湖北B村的考察发现:区域层面,社会化养老发展不足;社区层面,基础设施建设不到位;组织层面,农村社区组织在老年人照顾问题上存在“识盲”;家庭层面,家庭对老年人的照顾功能弱化;个人层面,存在着老年人的消极自我认知与身体病态化等问题。农村老年人照顾之所以问题化,与当前的城镇化进程息息相关。对此,可以引入社区为本的社会工作实践模式,通过整合性的社会工作介入手法,综合利用社会工作的个案、小组与社区工作等方法,从物质环境和人文环境两个维度,推动农村老年友好社区建设。

    2012-12-01

    The present study explores how close same-sex friendship groups participate in the co-construction of identities in the interpersonal domain during young adulthood. Participants included 24 same-sex college student friendship triads (12 male and 12 female; 72 total participants) who took part in semi-structured group interviews that elicited stories about conversations with their friends about dating relationship problems. Qualitative thematic analysis revealed five common responses to dating problems evidencing identity work in the context of friends' conversations. These responses included relating the issue to one's own experiences, providing validation and encouragement, joking about the problem, offering advice, and providing concrete instrumental support. Results are interpreted with regard to gender differences and similarities as well as the social context of college and developmental context of emerging adulthood. The findings identify ways in which young adults are actively co-constructing and re-evaluating their interpersonal identities within conversations with close same-sex friends. PMID:21986354

  5. Contribution to the construction of a reference biosphere, for the calculation of the radiation exposure emanating from a sealed final repository for radioactive wastes, including regional climate effects. Final report

    International Nuclear Information System (INIS)

    The assessment of the long-term safety of final repositories for radioactive wastes using doses or risks calculated in long-term safety analyses requires the utilisation of biosphere models. However, the evolution of the biosphere and, depending on it, the living and nutrition habits of man cannot be predicted in the timeframes under question since they strongly depend on climatic factors and changes of human society which are not amenable to prognoses even over short timeframes. Instead, in order to illustrate the hazard potentially caused by a repository, so-called reference biospheres can be utilised. A reference biosphere is a collection of assumptions and hypotheses necessary for a consistent base for the calculation of radiation exposure. It should be constructed in a way that exposure will not be underestimated but, at the same time, should be as simple as possible. In the report presented here the construction of such a biosphere is demonstrated. For this purpose biosphere models are developed starting with climatic conditions as they took place in northern Germany during the last million years and the influence of these models on radiation exposure is evaluated.

    Full Text Available Ordinary Portland cement production accounts for 9% of worldwide greenhouse gas emissions. This paper summarises the results of research aimed at developing environmentally-friendly binders which can be used as an alternative in civil construction, aimed at generating alternatives and sustainable materials. Mixes of the combination of granulated ground blast furnace slag, basic oxygen slag, cement kiln dust and plasterboard gypsum were used for optimising the binders, according to their compressive strength, to obtain 5 concrete mixtures made partially or completely with industrial waste. The results showed that the compressive strength of mixtures of Portland cement and industrial waste were suitable for different civil construction applications and, although mixtures formed entirely from industrial waste had a significant decrease in their compressive strength, the results sho- wed great potential for specific industrial applications. In addition to compressive strength, the rheological properties of these mixtures were determined for defining flow and workability characteristics.

    2016-06-01

    This study examines the effects of best friends' emotion regulation strategies (regarding the emotions anger, fear, and sadness) on the development of adolescents' emotion regulation strategies and subsequent depressive symptoms. Based on a two-wave longitudinal sample of 238 German adolescents, true change analyses showed positive effects of best friends' adaptive strategies (T1) on the change of adolescents' adaptive strategies (T2 - T1) for anger and fear. Best friends' adaptive strategies (T1) indirectly influence the development of maladaptive strategies (T2 - T1) through the change of adaptive strategies (T2 - T1) and, in turn, the development of depressive symptoms (T2 - T1; two-step mediation). Best friends' adaptive strategies for sadness did not have an effect on adolescents' adaptive strategies. In contrast to adaptive strategies, none of the friends' maladaptive strategies affected adolescents' maladaptive strategies. The results are discussed in terms of peer influences on the development of emotion regulation strategies and psychosocial adjustment. PMID:27060848

A large LGBT healthcare survey revealed that 56% of gay patients and 70% of transgender patients suffered some type of discrimination while seeking healthcare in 2014. The fostering of LGBT-friendly healthcare services is not just an advanced step of gender mainstreaming but also a fulfillment of health equality and equity. Additionally, LGBT-friendly healthcare services are expected to provide new opportunities for healthcare workers. Therefore, proactive government policies, education, research, and clinical practice should all encourage the development of these healthcare services. We look forward to a well-developed LGBT-friendly healthcare system in Taiwan. PMID:25631181

  1. Higgs friends and counterfeits at hadron colliders

    CERN Document Server

    Fox, Patrick J; Weiner, Neal

    2011-01-01

    We consider the possibility of "Higgs counterfeits" - scalars that can be produced with cross sections comparable to the SM Higgs, and which decay with identical relative observable branching ratios, but which are nonetheless not responsible for electroweak symmetry breaking. We also consider a related scenario involving "Higgs friends," fields similarly produced through gg fusion processes, which would be discovered through diboson channels WW, ZZ, gamma gamma, or even gamma Z, potentially with larger cross sections times branching ratios than for the Higgs. The discovery of either a Higgs friend or a Higgs counterfeit, rather than directly pointing towards the origin of the weak scale, would indicate the presence of new colored fields necessary for the sizable production cross section (and possibly new colorless but electroweakly charged states as well, in the case of the diboson decays of a Higgs friend). These particles could easily be confused for an ordinary Higgs, perhaps with an additional generation ...

  2. Gowers and Osler: good friends 'all through'.

    William Gowers and William Osler first met in 1878, and Osler visited Gowers often when in London. Osler dedicated his book On Chorea and Choreiform Affections to Gowers in 1894, addressing himself as Gowers' sincere friend. Two warm letters between Osler and Gowers exist in the Osler Library Archives, highlighting their strong friendship, and Gowers' son Ernest wrote Osler a letter after the death of his father. Referring to the relationship between William Osler and William Gowers, he noted that Osler had indeed been a good friend to him all through. Osler wrote and edited the first edition of his textbook from 1890 through early 1892, and was influenced by Gowers' Manual of Diseases of the Nervous System. In 1913, Osler commented that Gowers had ataxic paraplegia. Macdonald Critchley disagreed, and felt that Gowers had generalised cerebrovascular degeneration. Osler and Gowers were close friends, and this friendship was mutually beneficial. PMID:27092371

    2013-01-01

    Full Text Available The role of attachment to friends in the explanation of adolescents’ susceptibility to peer pressure was explored, regarding the way these two constructs are measured. In Study 1, 475 high school students (194 boys and 281 girls were given Susceptibility to Peer Pressure Questionnaire, and their attachment to friends was measured with Modified Experiences in Close Relationships Inventory and Relationship Scales Questionnaire. One month later, 80 boys and 80 girls participated in Study 2, where they completed the same Susceptibility to Peer Pressure Questionnaire in a chat-room simulation, convinced that they can see other students’ answers and that their own answers could be seen by others. When susceptibility to peer pressure was measured by self-report questionnaire, the level of avoidance proved to be a significant predictor for boys, while the level of anxiety and the model of others were significant predictors for girls. When susceptibility to peer pressure was measured experimentally, the results showed that attachment dimensions predict only girls’ susceptibility and that the only significant predictor is their model of others.

    Datasets that are derived from satellite observations are becoming increasingly important for measuring key parameters of the Earth's climate and are therefore crucial in research on climate change, giving the opportunity to researchers to detect anomalies and long-term trends globally. One of these key parameters is soil moisture (SM), which has a large impact on water, energy and biogeochemical cycles worldwide. A long-term SM data record from active and passive microwave satellite observations was developed as part of ESA's Climate Change Initiative (ESA-CCI-SM, http://www.esa-soilmoisture-cci.org/). Currently the dataset covers a period from 1978 to 2014 and is updated regularly, observations from a several microwave satellites including: ERS-1, ERS-2, METOP-A, Nimbus 7 SMMR, DMSP SSM/I, TRMM TMI, Aqua AMSRE, Coriolis WindSat, and GCOM-W1 AMSR2. In 2009, ESA launched the Soil Moisture and Ocean Salinity (SMOS, Kerr et al., 2010) mission, carrying onboard a unique L-band radiometer, but its SM retrievals are not yet part of this dataset. Due to the different radiometric characteristics of SMOS, integrating SMOS into the ESA-CCI-SM dataset is not straight forward. Therefore several approaches have been tested to fuse soil moisture retrievals from SMOS and AMSRE, which currently forms the basis of the passive microwave part within ESA-CCI-SM project. These approaches are: 1. A Neural Network Fusion approach (Rodríguez-Fernández et al., 2015), 2. A regression approach (Wigneron et al., 2004; Al-Yaari et al., 2015) and 3. A radiative transfer based approach, using the Land Parameter Retrieval Model (Van der Schalie et al., 2016). This study evaluates the three different approaches and tests their skills against multiple datasets, including MERRA-Land, ERA-Interim/Land, the current ESA-CCI-SM v2.2 and in situ measurements from the International Soil Moisture Network and present a recommendation for the potential integration of SMOS soil moisture into the ESA

    We consider the possibility of 'Higgs counterfeits' - scalars that can be produced with cross sections comparable to the SM Higgs, and which decay with identical relative observable branching ratios, but which are nonetheless not responsible for electroweak symmetry breaking. We also consider a related scenario involving 'Higgs friends,' fields similarly produced through gg fusion processes, which would be discovered through diboson channels WW,ZZ,{gamma}{gamma}, or even {gamma}Z, potentially with larger cross sections times branching ratios than for the Higgs. The discovery of either a Higgs friend or a Higgs counterfeit, rather than directly pointing towards the origin of the weak scale, would indicate the presence of new colored fields necessary for the sizable production cross section (and possibly new colorless but electroweakly charged states as well, in the case of the diboson decays of a Higgs friend). These particles could easily be confused for an ordinary Higgs, perhaps with an additional generation to explain the different cross section, and we emphasize the importance of vector boson fusion as a channel to distinguish a Higgs counterfeit from a true Higgs. Such fields would naturally be expected in scenarios with 'effective Z's,' where heavy states charged under the SM produce effective charges for SM fields under a new gauge force. We discuss the prospects for discovery of Higgs counterfeits, Higgs friends, and associated charged fields at the LHC.

    (Abridged) In tandem with observational datasets, we utilize realistic mock catalogs, based on a semi-analytic galaxy formation model, constructed specifically for Pan-STARRS1 Medium Deep Surveys in order to assess the performance of the Probability Friends-of-Friends (PFOF, Liu et al.) group finder, and aim to develop a grouping optimization method applicable to surveys like Pan-STARRS1. Producing mock PFOF group catalogs under a variety of photometric redshift accuracies ({\\sigma}{\\Delta}z/(1+zs)), we find that catalog purities and completenesses from ``good' {\\sigma}{\\Delta}z/(1+zs)) ~ 0.01) to ``poor' {\\sigma}{\\Delta}z/(1+zs)) ~ 0.07) photo-zs gradually degrade respectively from 77% and 70% to 52% and 47%. To avoid model dependency of the mock for use on observational data we apply a ``subset optimization' approach, using spectroscopic-redshift group data from the target field to train the group finder for application to that field, as an alternative method for the grouping optimization. We demonstrate th...

  19. Closing statement of Friends of the Earth Limited

    International Nuclear Information System (INIS)

    A closing statement is presented of the case by Friends of the Earth (FOE) against the proposed construction by UK Nirex Ltd of an underground Rock Characterisation Facility (RCF) at a site in the Sellafield area. The RCF is part of an investigation by Nirex into a suitable site for an underground repository for the disposal of radioactive waste. The objections were raised at a Planning Inquiry in 1995. The evidence provided by expert witnesses on behalf of FOE is summarised and reviewed. It concerns the adequacy of the geological characterisation and baseline monitoring work carried out by Nirex, and natural and induced changes to the geological barrier which may be associated with geological, engineering and chemical phenomena. Their detailed evidence has been presented to the Inquiry in other papers and constitutes the basis of the recommendation by FOE that planning consent for the RCF be refused. (UK)

    Nakajima, Miyoshi; Iio, Shouichiro; Ikeda, Toshihiko

    The aim of this investigation was to develop an environmentally friendly nano-hydraulic turbine. A model of a two-bucket Savonius type hydraulic turbine was constructed and tested in a water tunnel to arrive at an optimum installation condition. Effects of two installation parameters, namely a distance between a rotor and a bottom wall of the tunnel, a rotation direction of the rotor, on the power performance were studied. A flow field around the rotor was examined visually to clarify influences of installation conditions on the flow field. The flow visualization showed differences of flow pattern around the rotor by the change of these parameters. From this study it was found that the power performances of Savonius hydraulic turbine were changed with the distance between the rotor and the bottom wall of the tunnel and with a rotation direction of the rotor.

  1. Holocene construction and evolution of the Ganges-Brahmaputra-Meghna delta: the influence of climate, eustasy, and tectonics on stratigraphic architecture and fluvial dynamics

    The Ganges-Brahmaputra-Meghna delta (GBMD), an archetypal tidally-influenced deltaic margin, has been the subject of several multi-national, multi-institutional, and interdisciplinary field studies over the past several years, resulting in an unprecedented density of data coverage for stratigraphy, hydrodynamics, and tectonics on a scale previously only found on well-studied delta systems of other types (e.g., Nile, Mississippi, Rhine-Meuse). Using a suite of geochemical, geophysical, and lithologic data extracted from a network of over 400 shallow (sediments suggests the position of the Brahmaputra River was once west of its modern location, following a course along the eastern edge of the Tista Fan and west of the modern confluence with the Ganges. Construction of the modern delta, consisting of a thick (up to 80 m) succession of fluvial and deltaic sediments, was initiated by an intensified summer monsoon, coincident with accommodation generated by rapid sea-level rise following the Younger-Dryas. Sediment delivery has been focused along three pathways associated with antecedent topography inherited from Pleistocene lowstands. Stacked channel sands are the predominant facies within the upper delta, grading to isolated sand lenses in the distal reaches of Sylhet Basin, indicative of a shift from a highly mobile braidbelt to a less mobile distributary system as bedload is extracted to deposition. Episodic avulsions of the Brahmaputra River into Sylhet Basin during the mid-Holocene have been documented using a robust radiocarbon geochronology. The volume of sediment preserved from these events is insufficient to account for the entire sediment budget based on estimates of modern discharge, likely a consequence of both a weakened mid-Holocene monsoon and bypass out of the basin. Rapid (up to 7 mm/yr) subsidence in Sylhet Basin has not acted as an attractor for channel steering during much of the Holocene. Instead, the Brahmaputra has followed the steepest descent

    Full Text Available The present paper stems from the evidence that one of the reasons of the “crisis” of today's cities probably depend on mobility issues.   But what should be done to confront all the negative impacts of passenger transportation, without curbing mobility? Can Urban Engineering be applied to promote a friendlier mobility, that should be not only environment and climate friendly, but user friendly as well? And how? A "people friendly" accessibility approach is presented and conceived as a solution to better integrate land uses with the transport system, satisfying people's expectations (especially those of vulnerable users to easily reach the opportunities they wish to engage with.  The case study of Amsterdam, as walkable and cycle friendly city, is briefly presented and reveal good practices in the field of urban and mobility planning.  Finally, an isochronical accessibility analysis of Amsterdam is applied: it represent catchment areas of railways stations and of supermarkets, and it highlights how much the structure of the city supports bicycle use.

  5. A Practical Toolkit for Banks. Towards an Effective Climate Policy

    International Nuclear Information System (INIS)

    Climate change affects us all. Citizens, companies, governments and other organisations must all work to find solutions for this problem. Banks and financial institutions share this responsibility, as their loans and investments can have a strong influence on the development of polluting and clean industries, on climate friendly products and on other possibilities to reduce climate change. The good news is that more and more banks are acknowledging their responsibility. Several banks in the Netherlands and elsewhere have been trying to reduce their contribution to climate change in the past few years. Milieudefensie (Friends of the Earth Netherlands) urges Dutch banks to learn from these experiences and to take rapid and profound action in all the fields described in this climate policy toolkit. It is possible to sufficiently slow down climate change, but only if all concerned parties act fast

  6. Scaling Climate Change Communication for Behavior Change

    Rodriguez, V. C.; Lappé, M.; Flora, J. A.; Ardoin, N. M.; Robinson, T. N.

    2014-12-01

    Ultimately, effective climate change communication results in a change in behavior, whether the change is individual, household or collective actions within communities. We describe two efforts to promote climate-friendly behavior via climate communication and behavior change theory. Importantly these efforts are designed to scale climate communication principles focused on behavior change rather than soley emphasizing climate knowledge or attitudes. Both cases are embedded in rigorous evaluations (randomized controlled trial and quasi-experimental) of primary and secondary outcomes as well as supplementary analyses that have implications for program refinement and program scaling. In the first case, the Girl Scouts "Girls Learning Environment and Energy" (GLEE) trial is scaling the program via a Massive Open Online Course (MOOC) for Troop Leaders to teach the effective home electricity and food and transportation energy reduction programs. The second case, the Alliance for Climate Education (ACE) Assembly Program, is advancing the already-scaled assembly program by using communication principles to further engage youth and their families and communities (school and local communities) in individual and collective actions. Scaling of each program uses online learning platforms, social media and "behavior practice" videos, mastery practice exercises, virtual feedback and virtual social engagement to advance climate-friendly behavior change. All of these communication practices aim to simulate and advance in-person train-the-trainers technologies.As part of this presentation we outline scaling principles derived from these two climate change communication and behavior change programs.

    Norwegians are generally little impressed what Norway as a society has achieved in the climate policy. This is consistent with the actual situation as it is mapped in this year's edition of the Status of Norwegian climate policy. The results obtained in a survey by TNS Gallup which was commissioned by BI Centre for Climate Strategy in connection with the disclosure of the agency's annual status report for the Norwegian climate policy. 1000 Norwegians have been asked about how good or bad they perceive the overall results in various areas of climate policy. Even for climate-friendly heating, which is the area where most perceive that there has been progress, only 39% of the population consider the results as very good or good. In addition to heating, energy efficiency in buildings, Norway's international efforts, research on climate technology and information to the public areas where most Norwegians still think the results are good, and which are the least dissatisfied.Year Status Report on Norwegian climate policy is a joint project between the organization Holder de ord (Do they keep promises) and BI Centre for Climate Strategy. The report shows that people have a fairly accurate picture of climate policy. In most areas, there is little substantial progress since the Low Emission submitted its recommendations in 2006. It is symptomatic that climate policy was recently delayed again - now to 2012. While it is a positive development in the areas that are at the top of people's list. Since 2006, for example, there has been a substantial expansion of district heating in Norway, and building standards have become much stricter when it comes to energy use. Motor vehicle taxes are changed and greenhouse emissions from new cars is 25% lower than in 2006. Norway also play a constructive role, both in relation to the negotiations at the UN on a new climate deal, but also for example in relation to a global sectoral agreement for shipping that was signed

  9. I and My Friends are Good People: The Perception of Incivility by Self, Friends and Strangers

    Full Text Available Three studies were conducted to assess self-serving biases in participants’ beliefs about incivility, its antecedents and consequences as well as restitution behaviors and forgiveness as a function of whether a behavior was performed by themselves, strangers or friends. Participants who imagined themselves in the active role not only described their own behavior as more excusable, congruent with an actor-observer bias, but more importantly, they showed strong self-serving biases with regard to all their reactions to the situation – even though this leads to logical contradictions. This self-serving expectation generalized to friends and contrasted sharply with expectations for strangers, whose behaviors were described as logically consistent. The difference between what is expected from self and friends and what is expected from others may account for much of the popular moral outrage at incivility in various social realms.

  10. Environmentally Friendly Geopolymeric Binders Made with Perlite

    Production of Portland cement (PC), the ubiquitous binding material for construction works, is responsible for 5-10 % of all anthropogenic CO2 emissions. Nearly half of these emissions arise from the decomposition of calcareous raw materials, and the other half from kiln fuel combustion and cement clinker grinding operations. As such, PC production contributes significantly to global warming and climate change. Lately, there have been efforts to develop alternative binders with lower associated green house gas emissions. An important class of such binders is geopolymers, formed by activating natural or waste materials with suitable alkaline or acidic solutions. These binders have very low CO2 emissions from grinding of the starting material, and some from the production of the activating chemical. The total CO2 emission from carefully formulated mixtures can be as low as 1/5th - 1/10th of those of Portland cement concrete mixtures with comparable properties. While use of industrial wastes is environmentally preferable, the variability of their chemical compositions over time makes their use difficult. Use of natural materials depletes resources but can have more consistent properties and can be more easily accepted. Perlite is a volcanic aluminosilicate glass abundant in Turkey, China, Japan, the US and several EU countries. It has been used in its expanded form, for horticulture, for insulation, and for producing lightweight concrete. Turkish perlites contain more than 70 % SiO2, and have a SiO2/Al2O3 ratio of ~5.5. This study shows that ground perlite can be mixed with alkaline activators like sodium hydroxide or sodium silicate to yield mortars with strengths comparable to those of portland cement mortars. Strength gain is slower than with PC mixtures at room temperature but adequate ultimate strength can be achieved with curing at slightly elevated temperatures in 24 h or less. Since perlite is natural, perlite geopolymers can have environmental, energetic, and

  12. The CANDU contribution to environmentally friendly energy production

    International Nuclear Information System (INIS)

    National prosperity is based on the availability of affordable, energy supply. However, this need is tempered by a complementary desire that the energy production and utilization will not have a major impact on the environment. The CANDU energy system, including a next generation of CANDU designs, is a major primary energy supply option that can be an important part of an energy mix to meet Canadian needs. CANDU nuclear power plants produce energy in the form of medium pressure steam. The advanced version of the CANDU design can be delivered in unit modules ranging from 400 to 1200 MWe. This Next Generation of CANDU designs features lower cost, coupled with robust safety margins. Normally this steam is used to drive a turbine and produce electricity. However, a fraction of this steam (large or small) may alternatively be used as process steam for industrial consumption. Options for such steam utilization include seawater desalination, oil sands extraction and heating. The electricity may be delivered to an electrical grid or alternatively used to produce quantities of hydrogen. Hydrogen is an ideal clean transportation fuel because its use only produces water. Thus, a combination of CANDU generated electricity and hydrogen distribution for vehicles is an available, cost-effective route to dramatically reduce emissions from the transportation sector. The CANDU energy system contributes to environmental protection and the prevention of climate change because of its very low emission. The CANDU energy system does not produce any NOx, SOx or greenhouse gas (notably CO2) emissions during operation. In addition, the CANDU system operates on a fully closed cycle with all wastes and emissions fully monitored, controlled and managed throughout the entire life cycle of the plant. The CANDU energy system is an environmentally friendly and flexible energy source. It can be an effective component of a total energy supply package, consistent with Canadian and global climate

  14. Probability friends-of-friends (PFOF) group finder: Performance study and observational data applications on photometric surveys

    International Nuclear Information System (INIS)

    In tandem with observational data sets, we utilize realistic mock catalogs, based on a semi-analytic galaxy formation model, constructed specifically for Pan-STARRS1 Medium Deep Surveys to assess the performance of the Probability Friends-of-Friends (PFOF) group finder, and aim to develop a grouping optimization method applicable to surveys like Pan-STARRS1. Producing mock PFOF group catalogs under a variety of photometric redshift accuracies (σΔz/(1+zs)), we find that catalog purities and completenesses from 'good' (σΔz/(1+zs)∼ 0.01) to 'poor' (σΔz/(1+zs)∼ 0.07) photo-zs gradually degrade from 77% and 70% to 52% and 47%, respectively. A 'subset optimization' approach is developed by using spectroscopic-redshift group data from the target field to train the group finder for application to that field and demonstrated using zCOSMOS groups for PFOF searches within PS1 Medium Deep Field04 (PS1MD04) and DEEP2 EGS groups in PS1MD07. With four data sets spanning the photo-z accuracy range from 0.01 to 0.06, we find purities and completenesses agree with their mock analogs. Further tests are performed via matches to X-ray clusters. We find PFOF groups match ∼85% of X-ray clusters identified in COSMOS and PS1MD04, lending additional support to the reliability of the detection algorithm. In the end, we demonstrate, by separating red and blue group galaxies in the EGS and PS1MD07 group catalogs, that the algorithm is not biased with respect to specifically recovering galaxies by color. The analyses suggest the PFOF algorithm shows great promise as a reliable group finder for photometric galaxy surveys of varying depth and coverage.

    Most seedlings of crops are produced in solar greenhouse or nursery, from which some problems about energy waste and environment pollution arise. This study aims at investigating the characteristics and effect of an environmental friendly type seedling breeding system. The results demonstrate that crops can grow with a short period and little pollution in the new seedling breeding system with total manpower controllable environment that is not influenced by geography, climate and other natural conditions. By multilayer, nonplanar seedling breeding and annual batches arrangement, utilization ratio of unit area land and seedlings yield can be improved for several times and even more than 10 times. Conclusions can be obtained from the tomato seedling breeding experiments: (1) each growth index of tomato seedlings that are under the conditions of 291 μmol/m2 s artificial illumination intensity is remarkably better than those produced in greenhouse with natural lights. (2) The environment of the seedling breeding system can be accurately controlled. The segmented temperature changed management can be applied according to the photosynthetic characteristics of plants, and not affected by the outside environment, which makes each growth index of tomato seedling constant in different seasons. The seedlings thus grow strong and can achieve the level of commodity seedlings after 20-30 days. (3) The temperature and humidity environment of the seedling breeding system can be accurately controlled according to plants growth demands.

    International Nuclear Information System (INIS)

    Radon has two facets. On the one hand, it poses grave health hazards to not only uranium miners but also people living in normal houses and buildings. On the other hand, it helps in mineral exploration, earthquake prediction, study of volcanic activities, and search for geothermal energy sources. Some of the characteristics of radon are now well known, while others are yet to be explored. It has proved to be a good friend and a powerful enemy at the same time. This paper is a brief introduction of the potential benefits and possible threats of radon and its daughters. (author)

  1. Bayesian Auctions with Friends and Foes

    Science.gov (United States)

    Chen, Po-An; Kempe, David

    We study auctions whose bidders are embedded in a social or economic network. As a result, even bidders who do not win the auction themselves might derive utility from the auction, namely, when a friend wins. On the other hand, when an enemy or competitor wins, a bidder might derive negative utility. Such spite and altruism will alter the bidding strategies. A simple and natural model for bidders’ utilities in these settings posits that the utility of a losing bidder i as a result of bidder j winning is a constant (positive or negative) fraction of bidder j’s utility.

    Incumbent fiberglass compositions rely on decades of commercial experience. From a compositional point of view, many of these melts require more energy than needed in their production, or emit toxic effluents into the environment. This chapter reviews the design of energy- and/or environmentally friendly E-glass, HT-glass, ECR-glass, A-glass, and C-glass compositions, which have lower viscosities or fiber-forming temperatures and therefore require less energy in a commercial furnace than the respective incumbent compositions and/or do not contain ingredients which are of environmental concern.

    A new scientific and engineering discipline, Construction Biotechnology, is developing exponentially during the last decade. The major directions of this discipline are selection of microorganisms and development of the microbially-mediated construction processes and biotechnologies for the production of construction biomaterials. The products of construction biotechnologies are low cost, sustainable, and environmentally friendly microbial biocements and biogrouts for the construction ground improvement. The microbial polysaccharides are used as admixtures for cement. Microbially produced biodegradable bioplastics can be used for the temporarily constructions. The bioagents that are used in construction biotechnologies are either pure or enrichment cultures of microorganisms or activated indigenous microorganisms of soil. The applications of microorganisms in the construction processes are bioaggregation, biocementation, bioclogging, and biodesaturation of soil. The biotechnologically produced construction materials and the microbially-mediated construction technologies have a lot of advantages in comparison with the conventional construction materials and processes. Proper practical implementations of construction biotechnologies could give significant economic and environmental benefits. PMID:26070432

    2013-12-01

    In order to manufacture an eco-friendly stud, the sheared pattern is designed by the Taguchi method and expanded by the side rolls. The seven geometrical shape of sheared pattern are considered in the structural and thermal analyses to select the best functional one in terms of the durability and fire resistance of dry wall. For optimizing the size of the sheared pattern chosen, the L9 orthogonal array and smaller-the-better characteristics of the Taguchi method are used. As the roll gap causes forming defects when the upper-and-lower roll type is adopted for expanding the sheared pattern, the side roll type is introduced. The stress and strain distributions obtained by the FEM simulation of roll-forming processes are utilized for the design of expanding process. The expanding process by side rolls shortens the length of expanding process and minimizes the cost of dies. Furthermore, the stud manufactured by expanding the sheared pattern of the web is an eco-friend because of the scrapless roll-forming process. In addition, compared to the conventionally roll-formed stud, the material cost is lessened about 13.6% and the weight is lightened about 15.5%.

    1995-07-01

    The campaign for exclusive breast-feeding in a baby-friendly hospital at Prapokklao Hospital, Chanthaburi was increased. The contributory factors was likely due to enforcement of early bonding and attachment, by rooming-in of infants in the materity ward. After cessation of comprehensive intervention exclusive breast-feeding dropped significantly but increased in predominant breast-feeding. This might be due to family influence with the suggestion to give water in addition to breast milk. Data shows that rooming-in is essential in the promotion of breast-feeding. A decreased of abandoned children indicates early bonding. To sustain a baby-friendly hospital, 10 steps to successful breast-feeding must be followed strictly. Intervention activities must be done continuously with cooperation of health providers at all levels. It is felt that breast-feeding should not be considered a maternal instinct but a new behavior that needs to be changed to a point that mothers adopt breast-feeding practices for 4 months after delivery.

    In this paper, we analyze a collaborative filter that answers the simple question: What is popular amongst your friends? While this basic principle seems to be prevalent in many practical implementations, there does not appear to be much theoretical analysis of its performance. In this paper, we partly fill this gap. While recent works on this topic, such as the low-rank matrix completion literature, consider the probability of error in recovering the entire rating matrix, we consider probability of an error in an individual recommendation (bit error rate (BER)). For a mathematical model introduced in [1],[2], we identify three regimes of operation for our algorithm (named Popularity Amongst Friends (PAF)) in the limit as the matrix size grows to infinity. In a regime characterized by large number of samples and small degrees of freedom (defined precisely for the model in the paper), the asymptotic BER is zero; in a regime characterized by large number of samples and large degrees of freedom, the asymptotic B...

    Full Text Available The paper focuses on identifying the methods useful for improving the process of creating an innovation ­friendly environment. For this purpose, conditions for innovation activity in industry were investigated, and the expert evaluation of the selected knowledge and the assessment of the importance of skills for the successful development of innovations were car­ ried out. The work referred to the analysis of the sources of scientific information, a sociological inquiry of the personnel of industrial enterprises, correlation analysis and expert evaluation. The study has found that for building the innovation ­friendly environment, knowledge of the psychology of creativity, personnel management, formation and implementation of the innova­ tion strategy, risk management, business development and sales organization are of a particular importance. Expert assessment has showed that abilities to work in a team, be an entrepreneur, use marketing tools, generate ideas and create new products play a crucial role in innovation development. A situation in industry companies has shown the currently existing various groups of employees with a different point of view on the surveyed parameter. Managers, workers, engineers and other staff have different opinions and knowledge, and therefore a well thought­out policy is required for wider innovative activities. The directives of such a policy must be available for everyone.

    International Nuclear Information System (INIS)

    The Improved Korean Standard Nuclear Power Plant (KSNP+) design has been made possible on the basis of engineering experiences and referring to an in-depth analysis of the design and construction of all the domestic nuclear power plants in operation. The KSNP+ is designed for improved safety, better economics, operability and maintainability by means of advanced technology expecting to demonstrate enhanced performance. The plant also has incorporated several environmentally friendly features through the restoration of excavated areas using an ecological approach, external coloring, figure of turbine generator building and landscaping around nuclear power plant. This is the first time that KOPEC has embarked on inducing environmentally friendly features into the basic plan. This is expected to mitigate the negative perceptions held by the residents in the vicinity of nuclear power plants and will contribute to a new and improved image of nuclear power plants. (authors)

    Research suggests that college women are at greater risk for rape and sexual assault than women in the general population or in a comparable age group. College women, away from home and family, may turn to friends for support. Friends may experience emotional reactions that affect their own functioning and may not feel they have anywhere to turn. In this study, we interviewed male and female college students who had received a rape disclosure from a friend. Their unique stories provide insight into the secondary effects of rape disclosure on friends. Implications of these findings for college campuses are discussed. PMID:23743351

    The impacts of present and potential future climate change will be one of the most important scientific and societal challenges in the 21st century. Given observed changes in temperature, sea ice, and sea level, improving our understanding of the climate system is an international priority. This system is characterized by complex phenomena that are imperfectly observed and even more imperfectly simulated. But with an ever-growing supply of climate data from satellites and environmental sensors, the magnitude of data and climate model output is beginning to overwhelm the relatively simple tools currently used to analyze them. A computational approach will therefore be indispensable for these analysis challenges. This chapter introduces the fledgling research discipline climate informatics: collaborations between climate scientists and machine learning researchers in order to bridge this gap between data and understanding. We hope that the study of climate informatics will accelerate discovery in answering pressing questions in climate science.

    The trend in forestry practices today in Europe and U.S.A. in general and Scandinavian countries in particular, is towards adapting systems based on landscape planning. Thus common harvesting equipment available on the market will have to be replaced to meet these tough demands. Environmentalists recommend that wood fiber should be harvested either by selection cutting or commercial thinning thus leaving the site undisturbed with no sign of machine traffic. This mandate will preserve ground water quality and assist in soil conservation. However, to meet the pulp and paper as well as saw mill industries demand for wood from this method of cutting (selection or commercial thinning), requires a thorough examination of our harvesting systems and techniques. This paper will discuss present and future machines that are friendly to the environment. Hypothetical designs and improvements of existing machine systems will be addressed and recommendations will be made for future research activities. 75 refs, 8 figs, 1 tab

    CFCs and HCFCs, widely used in refrigeration and air-conditioning equipment, have been or will be phased out according to the revisions of the Montreal Protocol because they deplete the ozone layer. Many substitutes have been proposed, but no one has perfectly replaced the CFC end HCFC refrigerants. New generation alternatives are being investigated worldwide. According to the industrial and environmental requirements, many factors should be considered in the screening and evaluation of refrigerant alternatives. A new method is proposed using the soft algebra method——fuzzy multiple evaluation. The weights for different factors are determined mathematically and criteria values for all the objects are made dimensionless to quantitatively compare the different alternatives. A new long-term drop-in mixture alternative THR02 is developed and evaluated in a series of theoretical and experimental evaluations.THR02 is proved to be an environment-friendly, nontoxic, inflammable, drop-in alternative to CFC-12 a

However, because raw-earth constructions are a forgotten technique, we find problems of a lack of skilled people at all levels in this area, from designers to masons, as well as problems of how to carry out compatible conservation works on earthen ...

    Saving of toner/ink consumption is an important task in modern printing devices. It has a positive ecological and social impact. We propose technique for converting print-job pictures to a recognizable and pleasant color sketches. Drawing a "pencil sketch" from a photo relates to a special area in image processing and computer graphics - non-photorealistic rendering. We describe a new approach for automatic sketch generation which allows to create well-recognizable sketches and to preserve partly colors of the initial picture. Our sketches contain significantly less color dots then initial images and this helps to save toner/ink. Our bio-inspired approach is based on sophisticated edge detection technique for a mask creation and multiplication of source image with increased contrast by this mask. To construct the mask we use DoG edge detection, which is a result of blending of initial image with its blurred copy through the alpha-channel, which is created from Saliency Map according to Pre-attentive Human Vision model. Measurement of percentage of saved toner and user study proves effectiveness of proposed technique for toner saving in eco-friendly printing mode.

    Iran is one of the world's biggest petroleum exporting countries and a dominant actor in the Gulf region but in spite of this, the Iran government is faced with the same problems that developing states - and the Gulf states in particular - normally have. Problems on a national scale result mostly from the fact that most of the domestic petroleum production is also produced domestically, so there is less petroleum for exports. Iran's partnership in the international climate regime is particularly interesting as renewable energy is readily available on Iran terrain. This will motivate the country to establish a sustainable energy supply regime. (orig.)

  11. Incentives for environmentally friendly vehicles. A report from the Environment and Health Protection Administration in Stockholm

    Energy Technology Data Exchange (ETDEWEB)

    Henriksson, Cecilia; Paedam, S. [Inregia AB, Stockholm (Sweden)

    1999-11-01

    This report deals with incentives for environmentally friendly vehicles. The report includes a description of the current status of these vehicles in Sweden, Stockholm County Council, and the City of Stockholm. A forecast of possible development of zero and low emission vehicles is carried out. The major obstacles which currently hinder a market for these vehicles are noted. In order to determine market readiness and factors which affect these firms' purchase of vehicles, interviews were carried out with private firms. This analysis indicates that institutional barriers in Sweden hinder zero and low emission vehicles, with laws and tax policies which offer conflicting signals. To follow international developments, these obstacles must be reduced. Therefore, it is important that Stockholm works to create a positive climate for environmentally friendly vehicles. This means that it is important that the policies recommended in this report are implemented with adequate intensity. Because knowledge about zero and low emission vehicles is limited, there is a need to produce factual information. Information can be spread to a larger group, but it is more cost effective to reach a group which is most likely to accept environmentally friendly vehicles. This could include companies with environmental profiles, or those who drive and use company cars. To increase the effectiveness of this information campaign, we suggest that the City also maintain a demonstration fleet with loaner cars for companies who wish to test these vehicles in daily operation before deciding whether or not to purchase them. The incentive package recommended for Stockholm includes offering parking rebates to various groups who park in the city centre; residents , commercial vehicles, and temporary visitors. For equity reasons, all groups should in practice be offered the rebate. To increase the positive effect of the incentive, environmentally friendly vehicles should also be allowed to drive in

    Arts and climate science have more in common points than it appears at first glance. Artistic works can help us to directly or indirectly learn about climatic conditions and weather events in the past, but are also very efficient in raising awareness about climate change nowadays. Long scientific articles get very little response among general public, because most people don't want to read long articles. There is a need to communicate climate change issues more powerfully and more directly, with simple words, pictures, sculptures, installations. Artistic works can inspire people to take concrete action. A number of communication media can fit this purpose. Artists can speak to people on an emotional and intellectual level; they can help people to see things from another perspective and in new ways. Artists can motivate change; they have the freedom to weave facts, opinions, thoughts, emotion and colour all together. Paintings are witnesses of the past climatic conditions. We can learn from paintings, architectural constructions and sculptures about the vegetation, weather events, animals, and way of living. Mentioning only some few examples: old paintings in caves, also Flemish painters are often shown for their winter landscapes, and paintings are very useful to illustrate how fast glaciers are melting. At the end, we shall not forget that dilapidation of art masterpieces often depends on climatic conditions.

  7. The meaning and measurement of implementation climate

    Bergmire Dawn M

    2011-07-01

    Full Text Available Abstract Background Climate has a long history in organizational studies, but few theoretical models integrate the complex effects of climate during innovation implementation. In 1996, a theoretical model was proposed that organizations could develop a positive climate for implementation by making use of various policies and practices that promote organizational members' means, motives, and opportunities for innovation use. The model proposes that implementation climate--or the extent to which organizational members perceive that innovation use is expected, supported, and rewarded--is positively associated with implementation effectiveness. The implementation climate construct holds significant promise for advancing scientific knowledge about the organizational determinants of innovation implementation. However, the construct has not received sufficient scholarly attention, despite numerous citations in the scientific literature. In this article, we clarify the meaning of implementation climate, discuss several measurement issues, and propose guidelines for empirical study. Discussion Implementation climate differs from constructs such as organizational climate, culture, or context in two important respects: first, it has a strategic focus (implementation, and second, it is innovation-specific. Measuring implementation climate is challenging because the construct operates at the organizational level, but requires the collection of multi-dimensional perceptual data from many expected innovation users within an organization. In order to avoid problems with construct validity, assessments of within-group agreement of implementation climate measures must be carefully considered. Implementation climate implies a high degree of within-group agreement in climate perceptions. However, researchers might find it useful to distinguish implementation climate level (the average of implementation climate perceptions from implementation climate strength (the

  10. What Is a Friend? An Exploratory Typology of the Meanings of Friendship

    Verónica Policarpo

    2015-02-01

    Full Text Available In this article I explore the contemporary normative meanings of friendship, unpacking the subject through two different questions: “what is a good friend?” and “what is an intimate friend?” Drawing on survey data from a national representative sample (n = 1142, the topic is explored in the context of a southern European country (Portugal that represents an interesting case study, for its characteristics of late, though abrupt, entrance into late modernity. Statistical analysis of the results enabled the construction of an exploratory typology of representations of friendship, according to the meanings ascribed to friends: family-oriented; trust-oriented; self-oriented; and presence-oriented. Results inspire a two-folded interpretation. On the one hand, they point to a pervasiveness of hegemonic representations such as friendship as trust and self-disclosure, namely among the younger and more educated. On the other hand, they highlight the pervasiveness of kinship ties in the definition of friendship, namely among the elderly and less educated. This suggests that patterns of suffusion may not only refer to more individualized and plural arrangements of personal life, but also to the persistence of more traditional representations and practices, characterized by an ideological commitment to the family in its more institutional forms.

  11. Introduction of Microbial Biopolymers in Soil Treatment for Future Environmentally-Friendly and Sustainable Geotechnical Engineering

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available Soil treatment and improvement is commonly performed in the field of geotechnical engineering. Methods and materials to achieve this such as soil stabilization and mixing with cementitious binders have been utilized in engineered soil applications since the beginning of human civilization. Demand for environment-friendly and sustainable alternatives is currently rising. Since cement, the most commonly applied and effective soil treatment material, is responsible for heavy greenhouse gas emissions, alternatives such as geosynthetics, chemical polymers, geopolymers, microbial induction, and biopolymers are being actively studied. This study provides an overall review of the recent applications of biopolymers in geotechnical engineering. Biopolymers are microbially induced polymers that are high-tensile, innocuous, and eco-friendly. Soil–biopolymer interactions and related soil strengthening mechanisms are discussed in the context of recent experimental and microscopic studies. In addition, the economic feasibility of biopolymer implementation in the field is analyzed in comparison to ordinary cement, from environmental perspectives. Findings from this study demonstrate that biopolymers have strong potential to replace cement as a soil treatment material within the context of environment-friendly construction and development. Moreover, continuing research is suggested to ensure performance in terms of practical implementation, reliability, and durability of in situ biopolymer applications for geotechnical engineering purposes.

    Cygan, Marek; Pilipczuk, Michał; Wojtaszczyk, Jakub Onufry

    2012-01-01

    Signed graphs, i.e., undirected graphs with edges labelled with a plus or minus sign, are commonly used to model relationships in social networks. Recently, Kermarrec and Thraves initiated the study of the problem of appropriately visualising the network: They asked whether any signed graph can be embedded into the metric space R^l in such a manner that every vertex is closer to all its friends (neighbours via positive edges) than to all its enemies (neighbours via negative edges). Interestingly, embeddability into R^1 can be expressed as a purely combinatorial problem. In this paper we pursue a deeper study of this particular case, answering several questions posed by Kermarrec and Thraves. First, we refine the approach of Kermarrec and Thraves for the case of complete signed graphs by showing that the problem is closely related to the recognition of proper interval graphs. Second, we prove that the general case, whose polynomial-time tractability remained open, is in fact NP-complete. Finally, we provide lo...

  18. Fever and sickness behavior: Friend or foe?

    Science.gov (United States)

    Harden, L M; Kent, S; Pittman, Q J; Roth, J

    2015-11-01

    Fever has been recognized as an important symptom of disease since ancient times. For many years, fever was treated as a putative life-threatening phenomenon. More recently, it has been recognized as an important part of the body's defense mechanisms; indeed at times it has even been used as a therapeutic agent. The knowledge of the functional role of the central nervous system in the genesis of fever has greatly improved over the last decade. It is clear that the febrile process, which develops in the sick individual, is just one of many brain-controlled sickness symptoms. Not only will the sick individual appear "feverish" but they may also display a range of behavioral changes, such as anorexia, fatigue, loss of interest in usual daily activities, social withdrawal, listlessness or malaise, hyperalgesia, sleep disturbances and cognitive dysfunction, collectively termed "sickness behavior". In this review we consider the issue of whether fever and sickness behaviors are friend or foe during: a critical illness, the common cold or influenza, in pregnancy and in the newborn. Deciding whether these sickness responses are beneficial or harmful will very much shape our approach to the use of antipyretics during illness. PMID:26187566

  19. Making Rice Production More Environmentally-Friendly

    Directory of Open Access Journals (Sweden)

    Norman Uphoff

    2016-05-01

    Full Text Available Irrigated rice production is one of the most essential agricultural activities for sustaining our global population, and at the same time, one of the agricultural sectors considered most eco-unfriendly. This is because it consumes a larger share of available freshwater resources, competing with varied ecosystems as well as other economic sectors; its paddy fields are responsible for significant emission of greenhouse gases; and the reliance on chemical fertilizers and various agrochemicals contributes to pollution of soils and water systems. These stresses on soils, hydrology and atmosphere are actually not necessary for rice production, which can be increased by modifying agronomic practices though more agroecologically-sound management practices. These, combined under the rubric of the System of Rice Intensification (SRI, can reduce requirements of irrigation water, chemical fertilizer and agrochemicals while increasing paddy yields and farmer’s net incomes. Here we discuss how irrigated rice production can be made more eco-friendly for the benefit of farmers, consumers and the environment. This is achieved by introducing practices that improve the growth and functioning of rice plants’ root systems and enhance the abundance, diversity and activity of beneficial soil organisms that live around plant roots and within the plants themselves as symbiotic endophytes.

  20. The immunodepressive effect of Friend virus

    International Nuclear Information System (INIS)

    Splenic immune responses having varying dependence on accessory cell co-operation have been studied after infection of mice with Friend virus. Infection had no effect on cell proliferation or antibody production in cultures stimulated with E.coli lipopolysaccharide. The response in vivo to type III pneumococcal polysaccharide was depressed only moderately. The response to sheep red blood cells was depressed severely both in vivo and in vitro. Depression in vitro was greatly reduced by co-stimulation with E.coli lipopolysaccharide. Depletion of potential suppressor lymphocyte populations by irradiation or adult thymectomy did not ameliorate depression of responses to sheep red blood cells or pneumococcal polysaccharide. Responses after adult thymectomy plus irradiation were not affected by the virus. Although it is known that macrophage and helper T-lymphocyte co-operation are not themselves impaired by infection, these results suggest that there is a direct relationship between severity of immune depression and dependence on co-operation. Implications for the action of the virus are discussed. (author)

  1. The chemical industry - friend to the environment?

    International Nuclear Information System (INIS)

    ''The Chemical Industry - Friend to the Environment?'' was a symposium organised by the North East Region committee of the Industrial Division of the Royal Society of Chemistry. This volume contains typescripts from all the lectures given at the symposium. The general public appreciate the material comforts the Chemical Industry provides, for example textiles, ceramics, steel, speciality chemicals, drugs, prosthetics etc. However, for many their comfort is spoiled by the chemical poisoning of the environment through slag heaps, beaches and countryside littered with non-biodegradable unsightly plastic containers, poor air quality through NOx, CO2 and chlorofluorocarbon emissions, and of course, nuclear waste. The occasional spillage of hazardous chemicals through road, rail and sea accidents do nothing to improve the Industry's image. The majority of these topics were discussed, though no one presumed to know how to remove the problems entirely but many suggestions were put forward as to how this might be achieved. Of the 13 papers presented three were specifically concerned with recycling of plastics, 9 with the environmental impacts of chemicals and one, which is indexed separately, was concerned with radioactive discharges into the environment from the Sellafield reprocessing plant.

    A close-to-ideal blend of suburb and city, speedy construction of towers of Babylon, the sparkling proportion of glass and steel buildings’ facade at night showcase the wisdom of humans. They also witness the footsteps, sweats and tears of architects and engineers. Unfortunately, these signatures of human civilizations are swathed in towering figures of construction accidents. Fretting about these on sites, different countries adopt different measures on sites. This book firstly sketches the construction accidents on sites, followed by a review on safety measures in some of the developing countries such as Bermuda, Egypt, Kuwait and China; as well as developed countries, for example, the United States, France and Singapore. It also highlights the enormous compensation costs with the courts’ experiences in the United Kingdom and Hong Kong.

    International Nuclear Information System (INIS)

    Based on contributions on 120 French and foreign scientists representing different disciplines (mathematics, physics, mechanics, chemistry, biology, medicine, and so on), this report proposes an overview of the scientific knowledge and debate about climate change. It discusses the various indicators of climate evolution (temperatures, ice surfaces, sea level, biological indicators) and the various factors which may contribute to climate evolution (greenhouse gases, solar radiation). It also comments climate evolutions in the past as they can be investigated through some geological, thermal or geochemical indicators. Then, the authors describe and discuss the various climate mechanisms: solar activity, oceans, ice caps, greenhouse gases. In a third part, the authors discuss the different types of climate models which differ by the way they describe processes, and the current validation process for these models

  6. Making Climate Hot: Preparing Scientists and Teachers for Climate Change Communication and Education

    Science.gov (United States)

    Buhr, S. M.; Wise, S. B.

    2008-12-01

    Anyone associated with geoscience is increasingly asked to communicate about climate change with friends and family, media, the general public, and students. Scientists and teachers frequently find they lack the training to communicate with clarity about such a complex topic. Furthermore, needing to accommodate public controversy, common misconceptions, and contrarian arguments complicates the task. The CIRES Education and Outreach group has developed a short professional development workshop for this purpose titled 'Making Climate Hot: Effectively Communicating Climate Change'. The goals of the workshop are to make scientists and educators aware of best practices in science communication, provide research-based tools for crafting messages about climate change in particular, and allow participants to practice skills in a facilitated small group environment. Scientists and university communicators, teachers, environmental educators and college students have all participated in the 'Making Climate Hot' workshop. The workshop is customized to meet the needs of each sub-audience. We will present evaluation data from these different audiences.

    Although gratitude is a key prosocial emotion reinforcing reciprocal altruism, it has been largely ignored in the empirical literature. We examined feelings of gratitude and the importance of reciprocity in same-sex peer relations. Participants were 772 individuals (189 men; mean age = 28.80) who completed an online survey using a vignette design. We investigated (i) differences in reported gratitude and the importance of reciprocity among same-sex siblings and same-sex friends, and (ii) how relationship closeness moderates these associations. Based on the theory of kin altruism, we expect that people would feel more grateful towards friends than towards their siblings, and that lack of gratitude or failure to pay back a loan would bother more with friends than with siblings, irrespective of emotional closeness. Results showed that levels of gratitude and expectations of reciprocity were higher towards friends compared to siblings. This was the case also after controlling for emotional closeness. Being close generally made participants feel more grateful and expect lower displays of gratitude in the other. Closeness was also strongly associated with emotional gratitude among siblings compared to friends. We conclude that feelings and displays of gratitude have a special role in friendships. Although a close sibling may elicit as much gratitude as a friend does, even a very close friend is not exempt from the logic of reciprocity in the same way that a sibling is. PMID:25300047

    Full Text Available Abstract : There is a strong need to develop explosive reactive armour (ERA for protecting battle tanks against an emerging threat of kinetic and chemical energy missiles. In this context, global trends, principle and limitations of ERA and threat perception-based types of ERA have been dwelt upon. User-friendly ERA is a long-term reality. User-friendly ERA system is thus defined to be an efficient and protective system that not only provide full protection to the tank crew, but is also harmless to the supporting infantory. The indigenously-developed ERA system is close to be termed as a user-friendly ERA.

    We developed user-friendly empirical models to predict instantaneous fluxes of CO2 and CH4 from coastal wetlands based on a small set of dominant hydro-climatic and environmental drivers (e.g., photosynthetically active radiation, soil temperature, water depth, and soil salinity). The dominant predictor variables were systematically identified by applying a robust data-analytics framework on a wide range of possible environmental variables driving wetland greenhouse gas (GHG) fluxes. The method comprised of a multi-layered data-analytics framework, including Pearson correlation analysis, explanatory principal component and factor analyses, and partial least squares regression modeling. The identified dominant predictors were finally utilized to develop power-law based non-linear regression models to predict CO2 and CH4 fluxes under different climatic, land use (nitrogen gradient), tidal hydrology and salinity conditions. Four different tidal wetlands of Waquoit Bay, MA were considered as the case study sites to identify the dominant drivers and evaluate model performance. The study sites were dominated by native Spartina Alterniflora and characterized by frequent flooding and high saline conditions. The model estimated the potential net ecosystem carbon balance (NECB) both in gC/m2 and metric tonC/hectare by up-scaling the instantaneous predicted fluxes to the growing season and accounting for the lateral C flux exchanges between the wetlands and estuary. The entire model was presented in a single Excel spreadsheet as a user-friendly ecological engineering tool. The model can aid the development of appropriate GHG offset protocols for setting monitoring plans for tidal wetland restoration and maintenance projects. The model can also be used to estimate wetland GHG fluxes and potential carbon storage under various IPCC climate change and sea level rise scenarios; facilitating an appropriate management of carbon stocks in tidal wetlands and their incorporation into a

  12. Climate variability and climate change

    International Nuclear Information System (INIS)

    Changes of variability with climate change are likely to have a substantial impact on vegetation and society, rivaling the importance of changes in the mean values themselves. A variety of paleoclimate and future climate simulations performed with the GISS global climate model is used to assess how the variabilities of temperature and precipitation are altered as climate warms or cools. In general, as climate warms, temperature variability decreases due to reductions in the latitudinal temperature gradient and precipitation variability increases together with the intensity of the hydrologic cycle. If future climate projections are accurate, the reduction in temperature variability will be minimized by the rapid change in mean temperatures, but the hydrologic variability will be amplified by increased evapotranspiration. Greater hydrologic variability would appear to pose a potentially severe problem for the next century. 19 refs.; 3 figs.; 2 tabs

    The effects of changes in Global climate on the prolonging time and the frequency of the periods of very high outside air temperature at summer were shown in the paper with particular emphasis on European moderate climate countries. In these countries, residential buildings, are usually equipped neither in air conditioning equipment, nor in ordinary window blinds. As the most promising solution it is suggested to resign completely or partially from ground slab thermal insulation, directly utilizing ground heat storage capacity. The paper includes detailed simulations on potential effect of various kind of floor construction and actions preventing high indoor air temperatures in building approach on air temperature inside the one-storey, passive residential buildings during consecutive days of very high outdoor temperature and total energy used yearly for additional heating and air conditioning.

  16. Thermal baths as quantum resources: more friends than foes?

    Science.gov (United States)

    Kurizki, Gershon; Shahmoon, Ephraim; Zwick, Analia

    2015-12-01

    In this article we argue that thermal reservoirs (baths) are potentially useful resources in processes involving atoms interacting with quantized electromagnetic fields and their applications to quantum technologies. One may try to suppress the bath effects by means of dynamical control, but such control does not always yield the desired results. We wish instead to take advantage of bath effects, that do not obliterate ‘quantumness’ in the system-bath compound. To this end, three possible approaches have been pursued by us. (i) Control of a quantum system faster than the correlation time of the bath to which it couples: such control allows us to reveal quasi-reversible/coherent dynamical phenomena of quantum open systems, manifest by the quantum Zeno or anti-Zeno effects (QZE or AZE, respectively). Dynamical control methods based on the QZE are aimed not only at protecting the quantumness of the system, but also diagnosing the bath spectra or transferring quantum information via noisy media. By contrast, AZE-based control is useful for fast cooling of thermalized quantum systems. (ii) Engineering the coupling of quantum systems to selected bath modes: this approach, based on field-atom coupling control in cavities, waveguides and photonic band structures, allows one to drastically enhance the strength and range of atom-atom coupling through the mediation of the selected bath modes. More dramatically, it allows us to achieve bath-induced entanglement that may appear paradoxical if one takes the conventional view that coupling to baths destroys quantumness. (iii) Engineering baths with appropriate non-flat spectra: this approach is a prerequisite for the construction of the simplest and most efficient quantum heat machines (engines and refrigerators). We may thus conclude that often thermal baths are ‘more friends than foes’ in quantum technologies.

    2011-01-01

    We present a catalogue of galaxy groups and clusters selected using a friends-of-friends algorithm with a dynamic linking length from the 2dF-SDSS and QSO (2SLAQ) luminous red galaxy survey. The linking parameters for the code are chosen through an analysis of simulated 2SLAQ haloes. The resulting catalogue includes 313 clusters containing 1,152 galaxies. The galaxy groups and clusters have an average velocity dispersion of sigma_v = 467.97 km/s and an average size of R_clt = 0.78 Mpc/h. Galaxies from regions of one square degree and centred on the galaxy clusters were downloaded from the Sloan Digital Sky Survey Data Release 6 (SDSS DR6). Investigating the photometric redshifts and cluster red-sequence of these galaxies shows that the galaxy clusters detected with the FoF algorithm are reliable out to z~0.6. We estimate masses for the clusters using their velocity dispersions. These mass estimates are shown to be consistent with 2SLAQ mock halo masses. Further analysis of the simulation haloes shows that cli...

    Context. Groups form the most abundant class of galaxy systems. They act as the principal drivers of galaxy evolution and can be used as tracers of the large-scale structure and the underlying cosmology. However, the detection of galaxy groups from galaxy redshift survey data is hampered by several observational limitations. Aims. We improve the widely used friends-of-friends (FoF) group finding algorithm with membership refinement procedures and apply the method to a combined dataset of galaxies in the local Universe. A major aim of the refinement is to detect subgroups within the FoF groups, enabling a more reliable suppression of the Fingers-of-God effect. Methods. The FoF algorithm is often suspected of leaving subsystems of groups and clusters undetected. We use a galaxy sample built of the 2MRS, CF2, and 2M++ survey data comprising nearly 80 000 galaxies within the local volume of 430 Mpc radius to carry out FoF group detection. We conduct a multimodality check on the detected groups in search for subgr...

  1. The Centres for Environment-friendly Energy Research (FME)

    High expectations for Norway's Centres for Environment-friendly Energy Research (FME).The FME centres address a broad range of areas, allcentral to developing the energy sector of the future. The activities of the eight centres established in 2009 focus on renewable energy, raising energy efficiency, energy planning, and carbon capture and storage (CCS). In 2011 three new FME centres were established which focus on social science-related energy research. The FME scheme is a direct follow-up of the broad-based political agreement on climate policy achieved in the Storting in January 2008, and of the national RandD Energi21 strategy submitted in February 2008 to the Ministry of Petroleum and Energy. In April 2008 the Research Council of Norway's Executive Board decided to launch a process to establish centres for environment-friendly energy research, and a funding announcement was issued that same year. In 2010 it was decided that additional FME centres would be established in the field of social science-related energy research. After a thorough assessment of each project (based on feasibility, scientific merit, potential to generate value creation and innovation, and composition of the consortium) eight applicants were selected to become FME centres in February 2009. A new call for proposals was issued in 2010, and three more centres were awarded FME status in February 2011. The objective of the FME scheme is to establish time-limited research centres which conduct concentrated, focused and long-term research of high international calibre in order to solve specific challenges in the energy sphere. The selected centres must exhibit higher goals, a longer-term perspective and a more concentrated focus than is required under other funding instruments for the same scientific area. The make-up of the centres is critical to achieving this objective. The centres bring together Norway's leading research institutions and key players in private enterprise, the

    Full Text Available Sustenance of the human race has put an immense pressure on our planet Earth in terms of sustainability of natural resources. The greenhouse effect and the ozone hole are the two most threatening effects of pollution. Constructions of buildings as well as materials contribute to a large percentage to this pollution. Again every material used in the building industry has its source in the Earth. In general the low energy materials will be least polluting. The conventionally used building materials like bricks, cement, steel, timber, plastics, glass etc. usually involve huge transportation costs and also manufacturing processes which are detriment al to the environment. On the other hand the demand for new buildings as well as the cost of building construction is growing a tremendous pace. We have to search for alternative materials which are energy efficient, environment friendly and economical like our traditional building materials - mud walls and thatch roofs. Of all the alternatives available to us which lead the way to sustainability, building with earth has been an ancient and accepted practice among communities all over the world. It is estimated that the construction and the operation of buildings is responsible for around half of all glob al C02 emissions, thereby contributing the largest single source attributable to climate change. Earthen construction has been, is and will continue to be a reality. Stabilised rammed earth walls can be used as a building integrated source of passive cooling technique. A huge population in Indi a lives in the rural areas where there has been a growing trend in shifting towards brick and concrete constructions in search for social status. Even a small percentage can lead to massive increase in glob l C02 emissions if the trend is not checked at this point. This papers looks into the current scenario and hence the corresponding responsibility on architects, planners and policy makers to bring in

    Is having a friend from the opposite gender a help or a hindrance to getting good grades in high school? In new research using data on high school friendship networks and academic achievement, Andrew J. Hill finds that a ten percent increase in opposite gender friends reduces a students’ GPA score by 0.1 points. He writes that this effect on students can be found in mathematics and science subjects, but not in English and history.

    We show that the problem of directed percolation on an arbitrary lattice is equivalent to the problem of m directed random walkers with rather general attractive interactions, when suitably continued to m=0. In 1+1 dimensions, this is dual to a model of interacting steps on a vicinal surface. A similar correspondence with interacting self-avoiding walks is constructed for isotropic percolation.

  13. Constructing a framework for risk analyses of climate change effects on the water budget of differently sloped vineyards with a numeric simulation using the Monte Carlo method coupled to a water balance model

    Full Text Available Grapes for wine production are a highly climate sensitive crop and vineyard water budget is a decisive factor in quality formation. In order to conduct risk assessments for climate change effects in viticulture models are needed which can be applied to complete growing regions. We first modified an existing simplified geometric vineyard model of radiation interception and resulting water use to incorporate numerical Monte Carlo simulations and the physical aspects of radiation interactions between canopy and vineyard slope and azimuth. We then used four regional climate models to assess for possible effects on the water budget of selected vineyard sites up 2100. The model was developed to describe the partitioning of short-wave radiation between grapevine canopy and soil surface, respectively green cover, necessary to calculate vineyard evapotranspiration. Soil water storage was allocated to two sub reservoirs. The model was adopted for steep slope vineyards based on coordinate transformation and validated against measurements of grapevine sap flow and soil water content determined down to 1.6 m depth at three different sites over two years. The results showed good agreement of modelled and observed soil water dynamics of vineyards with large variations in site specific soil water holding capacity and viticultural management. Simulated sap flow was in overall good agreement with measured sap flow but site-specific responses of sap flow to potential evapotranspiration were observed. The analyses of climate change impacts on vineyard water budget demonstrated the importance of site-specific assessment due to natural variations in soil water holding capacity. The improved model was capable of describing seasonal and site-specific dynamics in soil water content and could be used in an amended version to estimate changes in the water budget of entire grape growing areas due to evolving climatic changes.

  15. Climate change and climate policy

    International Nuclear Information System (INIS)

    The climate issue is a great political and scientific challenge for several reasons: (1) There are many uncertain aspects of the climate problem, such as future emission of climate gases, the response of the climate system upon these gases, and the effects of climate changes. (2) It is probable, however, that anthropogenic emission of climate gases, deforestation etc. will cause noticeable climate changes in the future. This might be observed as increased frequency of extreme weather situations. This appears to be a greater threat than a gradual increase of temperature and precipitation. (3) Since the climate system is large and react only relatively slowly on changes in for instance the emission of climate gases, the climate problem can only be solved by means of long-term measures. (4) The climate changes may be irreversible. A rational short-term strategy is to ensure maximum flexibility, which can be done by ''slowing down'' (curtailing emissions) and by avoiding irreversible actions as much as possible. The long-term challenge is to develop an economically responsible alternative to the present fossil-based energy system that permits carbon-efficient technologies to compete on price with coal and unconventional oil and gas. Norway is in a special position by being a large exporter of fossil fuel and at the same time wanting to appear responsible in environmental matters. This combination may incur considerable expenses upon Norway and it is therefore important that environmental commitments like the Kyoto agreement can be honoured to the lowest possible cost. The costs can be minimized by: (1) minimizing the measure costs in Norway, (2) working to make the international quota price as low as possible, and (3) reducing the loss of petroleum income as much as possible. This report describes the earth's climate history, the forces behind climatic changes and what the prospects for the future look like. It also reviews what is being done to curtail the emission of

    Boulder, Colorado is a central hub of climate research and education resources, yet teachers less than two hours away struggle to find relevant climate curriculum and meaningful connections to climate scientists. Learn More About Climate (LMAC), an initiative of the CU-Boulder Office for Outreach and Engagement was created to provide access to the most up-to-date scientific research in a user-friendly way that raises awareness and inspires an informed dialogue about climate change among Coloradans. LMAC produces classroom ready videos highlighting CU climate scientists, offers classroom visits and Skype sessions with scientists, and serves as a hub for the most recent climate news. LMAC recently formed a Teacher Advisory Board made up of eleven K12 teachers from across Colorado spanning rural, suburban, and urban school districts. Given different locations, demographics, and grade levels, each teacher faces different challenges teaching climate. Here we present our work to identify the primary challenges that our teacher advisors have encountered while teaching climate science in their classrooms. Furthermore, we are working to co-create dynamic solutions with the teachers to address these problems using the LMAC platform.

    This book proposes both a scientific and societal approach of a phenomenon which is today the object of lot of debates. Climates perception is illustrated with examples taken in various modern civilizations and in the history of mankind. The Sahara example illustrates the notion of climate evolution. The last chapters are devoted to forecasting and scenarios for the future, taking into account the share of uncertainty. The controversies generated by these forecasts and the Kyoto protocol stakes demonstrate the tight links between the scientific, economical and political aspects in climatic change debates. (J.S.)

  2. Constructing Catalonia

    Directory of Open Access Journals (Sweden)

    Bill Phillips

    2009-01-01

    Full Text Available Catalonia, in common with other nations, has long b een concerned with the question of identity and difference. Its problemati c relationship with Spain has led to an emphasis on differentiating itself from its larger neighbour (if we are to accept, as most Spaniards do not, that Catalonia is not Spain, a s ituation complicated by the loss of the Spanish colonies of Cuba and The Philippines in 189 8, and the Spanish Civil War and subsequent dictatorship from 1936 to 1976. Beginnin g in the late nineteenth century, the construction of a Catalan identity followed a simil ar route to that taken by other European nations such as England, Ireland and, inde ed, Spain, including an emphasis on rural values, activities and the countryside, and t he conversion of specifically local traditions into national past times. It is only in the last ten years or so that this model of Catalan identity has been recognised for what it is – a model constructed and encouraged for and by specific nationalist politica l interests. Ironically, Catalonia’s identity abroad has also been constructed and manip ulated for political purposes, but from quite a different perspective. Orwell’s /Homag e to Catalonia/ (1938 narrates an extremely blinkered version of the Spanish Civil Wa r which has achieved iconic status as a result of cold war politics. Subsequent portra yals of the Spanish Civil War – Valentine Cunningham’s /The Penguin Book of Spanish Civil War Verse/ (ed., Penguin, 1980, or Ken Loach’s 1995 film /Land and F reedom/ base their arguments unquestioningly on /Homage to Catalonia/, perpetuat ing a view of the nation’s recent history that is both reductive and inaccurate

    Current Climate Variability & Change is the ninth among a suite of ten interconnected, sequential labs that address all 39 climate-literacy concepts in the U.S. Global Change Research Program's Climate Literacy: The Essential Principles of Climate Sciences. The labs are as follows: Solar Radiation & Seasons, Stratospheric Ozone, The Troposphere, The Carbon Cycle, Global Surface Temperature, Glacial-Interglacial Cycles, Temperature Changes over the Past Millennium, Climates & Ecosystems, Current Climate Variability & Change, and Future Climate Change. All are inquiry-based, on-line products designed in a way that enables students to construct their own knowledge of a topic. Questions representative of various levels of Webb's depth of knowledge are embedded in each lab. In addition to the embedded questions, each lab has three or four essential questions related to the driving questions for the lab suite. These essential questions are presented as statements at the beginning of the material to represent the lab objectives, and then are asked at the end as questions to function as a summative assessment. For example, the Current Climate Variability & Change is built around these essential questions: (1) What has happened to the global temperature at the Earth's surface, in the middle troposphere, and in the lower stratosphere over the past several decades?; (2) What is the most likely cause of the changes in global temperature over the past several decades and what evidence is there that this is the cause?; and (3) What have been some of the clearly defined effects of the change in global temperature on the atmosphere and other spheres of the Earth system? An introductory Prezi allows the instructor to assess students' prior knowledge in relation to these questions, while also providing 'hooks' to pique their interest related to the topic. The lab begins by presenting examples of and key differences between climate variability (e.g., Mt. Pinatubo eruption) and

  9. Habitable Climates

    CERN Document Server

    Spiegel, David S; Scharf, Caleb A

    2007-01-01

    The Earth is only partially habitable according to the standard liquid-water definition. We reconsider planetary habitability in the framework of energy-balance models, the simplest seasonal models in physical climatology, to assess the spatial and temporal habitability of Earth-like planets. In order to quantify the degree of climatic habitability of our models, we define several metrics of fractional habitability. Previous evaluations of habitable zones may have omitted important climatic conditions by focusing on close Solar System analogies. For example, we find that model pseudo-Earths with different rotation rates or different land-ocean fractions generally have fractional habitabilities that differ significantly from that of the Earth itself. Furthermore, the stability of a planet's climate against albedo-feedback snowball events strongly impacts its habitability. Therefore, issues of climate dynamics may be central in assessing the habitability of discovered terrestrial exoplanets, especially if astro...

  10. Climate catastrophes

    Budyko, Mikhail

    1999-05-01

    Climate catastrophes, which many times occurred in the geological past, caused the extinction of large or small populations of animals and plants. Changes in the terrestrial and marine biota caused by the catastrophic climate changes undoubtedly resulted in considerable fluctuations in global carbon cycle and atmospheric gas composition. Primarily, carbon dioxide and other greenhouse gas contents were affected. The study of these catastrophes allows a conclusion that climate system is very sensitive to relatively small changes in climate-forcing factors (transparency of the atmosphere, changes in large glaciations, etc.). It is important to take this conclusion into account while estimating the possible consequences of now occurring anthropogenic warming caused by the increase in greenhouse gas concentration in the atmosphere.

  11. Climatic change

    International Nuclear Information System (INIS)

    In spite of man's remarkable advances in technology, ultimately he is still dependent on the Earth's climatic system for food and fresh water. The recent occurrences in certain regions of the world of climatic extremes such as excessive rain or droughts and unseasonably high or low temperatures have led to speculation that a major climatic change is occurring on a global scale. Some point to the recent drop in temperatures in the northern hemisphere as an indication that the Earth is entering a new ice age. Others see a global warming trend that may be due to a build-up of carbon dioxide in the atmosphere. An authoritative report on the subject has been prepared by a World Meteorological Organization Panel of Experts on Climatic Change. Excerpts from the report are given. (author)

    Purpose The purpose of this study was to explore how behavioral, intra-personal and socio-environmental factors were associated with the likelihood of having at least one older friend. Methods Participants included 3709 ethnically-diverse 8th grade students in the Project Northland Chicago intervention trial. Socio-demographic characteristics included gender, family composition, language spoken at home, race/ethnicity, and age. Behavioral factors included cigarette, alcohol, and marijuana use, depressed feelings, willingness to wear alcohol-branded merchandise, and violent and delinquent behavior. Intrapersonal factors included low refusal self efficacy and outcome expectations and expectancies. Socio-environmental factors included alcohol offers and access, normative estimates and expectations, and peer alcohol use. Having an older friend was defined as having at least one friend aged 16 or older (students’ mean age=14.2). Logistic mixed-effects regression models were used and controlled for gender, race/ethnicity, treatment status, and age. Results Females and older eighth graders were significantly more likely to have at least one older friend. Students who scored higher on all of the behavioral, intra-personal and socio-environmental risk factors were significantly more likely to have at least one older friend. Significant gender interactions were found for several of the relationships. Conclusion Overall this study found multiple risk-related factors are associated with having older friends in eighth grade. Particularly important factors appear to be cigarette, marijuana and alcohol use, having friends who use alcohol, having increased alcohol offers, and being willing to wear or use alcohol-branded merchandise.

    International Nuclear Information System (INIS)

    Europe sees itself on the forefront to combat climate change. Consequently, the European Union has adopted in 2003 a Directive on Emissions Trading and since then, focuses more and more on effective methods to reduce greenhouse gas emissions. So far, there is little knowledge about the further development of Climate Change Policy in Europe after 2012. The EU has already started a review process to define the new legislation starting in 2013. Furthermore, negotiations take place to develop a successor of the Kyoto protocol. The European energy sector can deliver valuable input to the discussion about the coming climate goals and how to achieve them, by addressing the importance of new climate-friendly technologies. Furthermore, the impact of climate change goals on the current investment decisions in the energy sector has to be stressed. Europe will certainly not solve the climate problem on its own, but can help to deliver abatement technologies and to prove, that climate change can be reconciled with economic growth - provided a long-term framework is established that is in line with other goals like security of supply and affordable energy.(author).

  20. Climate certificates

    International Nuclear Information System (INIS)

    Reduced emissions of climate gases at the lowest cost require international cooperation in order to ensure that the most cost-efficient measures are taken. A market for emission rights is one way of achieving this. However, creating the right conditions for such a market to operate requires an unambiguous definition of the product to be traded. In this PM, the Swedish Power Association sketches out how such a product could be defined, and how a market for the resulting unambiguously defined product could be operated internationally, in parallel with other markets for energy products. Trade in climate certificates could become a joint EU approach to achieving common results within the field of climate policy. The main features of the proposal are as follows: Electricity producers would be allowed to issue climate certificates for electricity produced without climate-affecting emissions, e.g. in wind power plants. 1 kWh of electricity produced without emissions would entitle the utility to issue a climate certificate for 1 kWh. Electricity from power stations having low emissions, e.g. modern natural gas-fired plants, would entitle the utility to issue certificates in proportion to how much lower their emissions were in comparison with those from conventional coal-fired power stations. The number of certificates would be reduced by an individual coefficient, related directly to the quantity of climate-affecting emissions from the plant concerned. They would be traded and noted on markets in the various member countries. The certificates would not be nationally restricted, but could be traded across borders. Exchanges would be authorised by national authorities, in accordance with overall EU directives. These authorised exchanges would act as certification bodies, checking that certificates had been properly issued in accordance with a corresponding volume of electricity production. Electricity and certificates could be purchased from different suppliers. The

  1. Organizational Climate for Successful Aging.

    Zacher, Hannes; Yang, Jie

    2016-01-01

    Research on successful aging at work has neglected contextual resources such as organizational climate, which refers to employees' shared perceptions of their work environment. We introduce the construct of organizational climate for successful aging (OCSA) and examine it as a buffer of the negative relationship between employee age and focus on opportunities (i.e., beliefs about future goals and possibilities at work). Moreover, we expected that focus on opportunities, in turn, positively predicts job satisfaction, organizational commitment, and motivation to continue working after official retirement age. Data came from 649 employees working in 120 companies (M age = 44 years, SD = 13). We controlled for organizational tenure, psychological climate for successful aging (i.e., individuals' perceptions), and psychological and organizational age discrimination climate. Results of multilevel analyses supported our hypotheses. Overall, our findings suggest that OCSA is an important contextual resource for successful aging at work. PMID:27458405

  2. Getting to Family-Friendly in Your Department

    Pilachowski, Catherine A.

    2012-01-01

    These days, most academic and research institutions recognize the importance of a family-friendly workplace, and have implemented at least some policies to support a sustainable work-life balance: family and medical leave, parental leave, stopping or extending tenure clocks, modified duty policies, breast feeding policies and lactation rooms, partner hiring programs, childcare programs, eldercare programs, emergency and sick child care programs, dependent care travel funds, etc. But while institutions may offer a menu of policies and free or low-cost services to support families, what's happening in your department? Achieving a supportive workplace culture requires that we dispel some of the myths associated with family-friendly policies, and establish that family-friendly policies not only benefit all employees, but also help the institution be more successful.

  3. Cyber Friendly Fire: Research Challenges for Security Informatics

    2013-06-06

    This paper addresses cognitive implications and research needs surrounding the problem of cyber friendly fire (FF). We define cyber FF as intentional offensive or defensive cyber/electronic actions intended to protect cyber systems against enemy forces or to attack enemy cyber systems, which unintention-ally harms the mission effectiveness of friendly or neutral forces. Just as with combat friendly fire, maintaining situation awareness (SA) is paramount to avoiding cyber FF incidents. Cyber SA concerns knowledge of a system’s topology (connectedness and relationships of the nodes in a system), and critical knowledge elements such as the characteristics and vulnerabilities of the components that comprise the system and its nodes, the nature of the activities or work performed, and the available defensive and offensive countermeasures that may be applied to thwart network attacks. Mitigation strategies to combat cyber FF— including both training concepts and suggestions for decision aids and visualization approaches—are discussed.

    There is a growing recognition that mitigation measures for limiting future global changes in climate due to the enhanced greenhouse effect are unlikely to prevent some changes from occurring. Thus, if climate changes appear to be unavoidable, there is an increased need to evaluate their likely impacts on natural systems and human activities. Most impacts of climate change need to be examined at a regional scale, and their assessment requires up-to-date information on future regional climate changes. Unfortunately, accurate predictions of regional climate are not yet available. Instead, it is customary to construct climatic scenarios, which are plausible representations of future climate based on the best available information. This presentation outlines seven principles of climatic scenario development for impact studies, briefly describing some of the strengths and weaknesses of available methods and then illustrating one approach adopted in Finland

    Context. Groups form the most abundant class of galaxy systems. They act as the principal drivers of galaxy evolution and can be used as tracers of the large-scale structure and the underlying cosmology. However, the detection of galaxy groups from galaxy redshift survey data is hampered by several observational limitations. Aims: We improve the widely used friends-of-friends (FoF) group finding algorithm with membership refinement procedures and apply the method to a combined dataset of galaxies in the local Universe. A major aim of the refinement is to detect subgroups within the FoF groups, enabling a more reliable suppression of the fingers-of-God effect. Methods: The FoF algorithm is often suspected of leaving subsystems of groups and clusters undetected. We used a galaxy sample built of the 2MRS, CF2, and 2M++ survey data comprising nearly 80 000 galaxies within the local volume of 430 Mpc radius to detect FoF groups. We conducted a multimodality check on the detected groups in search for subgroups. We furthermore refined group membership using the group virial radius and escape velocity to expose unbound galaxies. We used the virial theorem to estimate group masses. Results: The analysis results in a catalogue of 6282 galaxy groups in the 2MRS sample with two or more members, together with their mass estimates. About half of the initial FoF groups with ten or more members were split into smaller systems with the multimodality check. An interesting comparison to our detected groups is provided by another group catalogue that is based on similar data but a completely different methodology. Two thirds of the groups are identical or very similar. Differences mostly concern the smallest and largest of these other groups, the former sometimes missing and the latter being divided into subsystems in our catalogue. The catalogues are available at the CDS via anonymous ftp to http://cdsarc.u-strasbg.fr (ftp://130.79.128.5) or via http://cdsarc

    This study develops two useful procedures in performing an environmental-impact assessment. One is the advanced life-cycle assessment (LCA) method, which effectively tracks the flow of materials and considers the recycling and demolition of a civil structure. The other is an eco-friendly decision-making procedure, which may effectively apply when determining the prototype of a civil structure. The advanced LCA method differs from traditional LCA procedure, as it classifies the input material prior to the impact assessment. Classification work is performed to establish independent life-cycle stages for each material. The processes of recycling and demolition are appropriately added to the life-cycle stages. The impact assessment is performed separately for the materials, and results are aggregated at the end of the analysis. The eco-friendly decision-making procedure enables designers to choose an economical, and environmentally friendly, alternative during the planning phase of the construction project. This procedure rationally amalgamates economical value and environmental effects into a single indicator. The life cycle cost (LCC) of a structure can be analysed by using conventional LCC tools, whereas the environmental impact is estimated by LCA. The results from LCC and LCA are then integrated by using either a CO2 conversion method or an analytical hierarchy process (AHP). The CO2 conversion method presents the result as a monetary value, whereas the AHP presents the result as a non-dimensional value. A practical example using a steel box girder bridge and a pre-stressed concrete (PSC) box-girder bridge is also given in order to aid the understanding of the presented procedure. PMID:23681357

    The present research examined bystander responses to potential party rape scenarios involving either a friend or a stranger at risk. Undergraduate students (N = 151) imagined attending a party and seeing a man lead an intoxicated woman (friend or stranger) into a bedroom. After random assignment to conditions, participants reported on intentions to help, barriers to helping, victim blame, and empathic concern. As expected, based on their shared social group membership, bystanders intended to offer more help to friends than to strangers. Bystanders also reported more personal responsibility to help and more empathic concern when the potential victim was a friend rather than stranger. Observing a friend versus stranger at risk did not affect audience inhibition or perceived victim blame. Compared with women, men reported more blame and less empathic concern for potential victims. However, there were no gender differences in bystander intent to help or barriers to helping. In multivariate analyses, both responsibility to help and empathic concern for the potential victim uniquely predicted bystanders' intent to help a woman at risk for party rape. Results suggest that promoting social identification with peers at risk could increase bystander intervention. PMID:25349015

  11. Constructing Brambles

    Chapelle, Mathieu; Mazoit, Frédéric; Todinca, Ioan

    Given an arbitrary graph G and a number k, it is well-known by a result of Seymour and Thomas [22] that G has treewidth strictly larger than k if and only if it has a bramble of order k + 2. Brambles are used in combinatorics as certificates proving that the treewidth of a graph is large. From an algorithmic point of view there are several algorithms computing tree-decompositions of G of width at most k, if such decompositions exist and the running time is polynomial for constant k. Nevertheless, when the treewidth of the input graph is larger than k, to our knowledge there is no algorithm constructing a bramble of order k + 2. We give here such an algorithm, running in {mathcal O}(n^{k+4}) time. For classes of graphs with polynomial number of minimal separators, we define a notion of compact brambles and show how to compute compact brambles of order k + 2 in polynomial time, not depending on k.

  12. Environmentally friendly, high-performance generation

    International Nuclear Information System (INIS)

    The project developer, owner, and operator of the new 45 MWth BFB-based cogeneration plant in Iisalmi is Termia Oy, part of the Atro Group (formerly Savon Voima Oy). Fired on peat and wood waste and handed over to the customer in November 2002, the plant's electrical output is sold to the parent company and heat locally to customers in Iisalmi. When the construction decision was made, one of the main objectives was to utilise as high a level of indigenous fuels (peat and biomass) as possible, at a high level of efficiency. An environmental impact analysis was carried out, taking into account the impact of various fuels and emissions in terms of combustion and logistics. One main benefit of the type of plant ultimately selected was that the bulk of the fuel can be supplied from the surrounding area. This is very important in terms of fuel supply security and local employment. The government provided a EUR 2.7 million grant for the project, equivalent to 13% of the total EUR 21 million investment budget. Before the plant was built, Termia used approximately 95 GWh of indigenous fuels annually. Today, this figure is 220 GWh. The main fuel used is milled peat. Up to 30% green chips from logging residues can be used. Recycled waste fuel can cover up to 3% of the total fuel requirement

    In the Patent Office Einstein hatched his most beautiful ideas, and there he spent his "Happy Bern Years". These wonderful ideas led to his miraculous year works of 1905. Einstein was not an expert in academic matters, and he was out of academic world. Neither did he meet influential professors, or attend academic meetings. He discussed his ideas with his close friends and colleagues from the Patent Office. In 1907 he finally got his foot into the academic doorway; Einstein became a privatdozent and gave lectures at the University of Bern. However, his first students consisted again of his two close friends and another colleague from the Patent Office.

  17. Moving to Google Cloud: Renovation of Global Borehole Temperature Database for Climate Research

    2013-12-01

    Borehole temperature comprises an independent archive of information on climate change which is complementary to the instrumental and other proxy climate records. With support from the international geothermal community, a global database of borehole temperatures has been constructed for the specific purpose of the study on climate change. Although this database has become an important data source in climate research, there are certain limitations partially because the framework of the existing borehole temperature database was hand-coded some twenty years ago. A database renovation work is now underway to take the advantages of the contemporary online database technologies. The major intended improvements include 1) dynamically linking a borehole site to Google Earth to allow for inspection of site specific geographical information; 2) dynamically linking an original key reference of a given borehole site to Google Scholar to allow for a complete list of related publications; and 3) enabling site selection and data download based on country, coordinate range, and contributor. There appears to be a good match between the enhancement requirements for this database and the functionalities of the newly released Google Fusion Tables application. Google Fusion Tables is a cloud-based service for data management, integration, and visualization. This experimental application can consolidate related online resources such as Google Earth, Google Scholar, and Google Drive for sharing and enriching an online database. It is user friendly, allowing users to apply filters and to further explore the internet for additional information regarding the selected data. The users also have ways to map, to chart, and to calculate on the selected data, and to download just the subset needed. The figure below is a snapshot of the database currently under Google Fusion Tables renovation. We invite contribution and feedback from the geothermal and climate research community to make the

    This paper presented indicators of climate change for British Columbia (BC) with an emphasis on the coastal region. An overview of global effects of climate change was presented, as well as details of BC's current climate change action plan. Indicators examined in the paper for the BC coastal region included long-term trends in air temperature; long-term trends in precipitation; coastal ocean temperatures; sea levels on the BC coast; and the sensitivity of the BC coast to sea level rise and erosion. Data suggested that average air temperatures have become higher in many areas, and that Springtime temperatures have become warmer over the whole province. Winters have become drier in many areas of the province. Sea surface temperature has risen over the entire coast, with the North Coast and central Strait of Georgia showing the largest increases. Deep-water temperatures have also increased in 5 inlets on the South Coast. Results suggested that the direction and spatial pattern of the climate changes reported for British Columbia are consistent with broader trends in North America and the type of changes predicted by climate models for the region. Climate change will likely result in reduced snow-pack in southern BC. An earlier spring freshet on many snow-dominated river systems is anticipated as well as glacial retreat and disappearance. Warmer temperatures in some lakes and rivers are expected, as well as the increased frequency and severity of natural disturbances such as the pine mountain beetle. Large-scale shifts in ecosystems and the loss of certain ecosystems may also occur. BC's current climate plan includes cost effective actions that address GHG emissions and support efficient infrastructure and opportunities for innovation. Management programs for forest and agricultural lands have been initiated, as well as programs to reduce emissions from government operations.

    A large amount of hazardous trichloromonofluoromethane (CFC-11) is contained in the polyurethane (PUR) foam of refrigerator cabinet. How to recover the cabinet of waste refrigerator with environmental awareness has been the pressing problem in the treatment of waste refrigerator. The published literature of waste refrigerator cabinets recovering mainly focuses on policy making and conceptual design. Little information relates to the production line of waste refrigerator cabinet recovering and its detailed operation, which is the urgent needed literature. In this paper, an environmental friendly production line for recovering the cabinet of waste refrigerators was reported for helping enterprise or government to construct line to recover the obsolete refrigerators. It included closed shearing process, activated carbon fiber absorption (ACFA) process, air current separation, and magnetic/eddy current separation. The optimized operating parameters of every process were obtained from the experiments. Then, experiment of recovering 50 waste refrigerator cabinets by the production line was performed in factory. Mass balances of the recovered materials were carried out. The result shown the recovery rate of waste refrigerator cabinet could reach 97.6%. Finally, comparison between the production line and other recovery technologies was made. The results indicated that the proposed line provided environment-friendly recovery of waste refrigerator cabinets while achieving low cost of production. PMID:21782408

    By selecting the data from 1989 to 2009 in China, we conduct regression analysis on the total output value of agriculture, the usage amount of chemical fertilizer, total power of agricultural machinery, effective irrigation area, and the damage area. The results show that the usage amount of chemical fertilizer and the damage area, the great obstacle to the construction of resource-saving and environment-friendly agriculture, have significant impact on the output value of agriculture; total power of agricultural machinery and effective irrigation area have insignificant impact on the output value of agriculture. Based on these, the suggestions for promoting the development of resource-saving and environment-friendly agriculture are put forward as follows: transform agricultural production mode, and optimize the industrial structure of agriculture; promote scientific use of chemical fertilizer, and promote the ability of agriculture to resist risks; promote the development of biogas in rural areas, and carry out the comprehensive use of biological material resources in rural areas.

    Limited non-renewable fossil energy reserves and the essential ideas of sustainability have caused an increase in the demand for solar energy. The intensified use of renewable energy in Germany is primarily encouraged by the German renewable-energy-law. Solar panels mounted on roofs generate electricity using the energy radiated from the sun by taking advantage of the photovoltaic effect. However, not every roof is usable for power generation through solar energy. Therefore, web-based solar energy registers for multiple regions in Germany have been developed that provide detailed information on roofs suitable for carrying solar panels. The analyses are based on a digital object model derived from airborne laser scanning data of high accuracy and a fully automated technology to classify the points. First, roof points are separated according to their single roof sides and are converted into polygons. Then, exposure, slope, size of the roof, and particularly shading effects are computed to calculate the solar potential of each roof side. The web-GIS provides detailed information about the roof's suitability, such as the installable capacity and the expected generation of electricity. Thus, it helps house owners to calculate their investment and later revenues.

    Agriculture is responsible for 17–35% of global anthropogenic greenhouse gas emissions with livestock production contributing by approximately 18–22% of global emissions. Due to high monitoring costs and low technical potential for emission reductions, a tax on consumption may be a more efficient...... policy instrument to decrease emissions from agriculture than a tax based directly on emissions from production. In this study, we look at the effect of internalising the social costs of greenhouse gas emissions through a tax based on CO2 equivalents for 23 different foods. Furthermore, we compare the...... loss in consumer surplus and the changed dietary composition for different taxation scenarios. In the most efficient scenario, we find a decrease in the carbon footprint from foods for an average household of 2.3–8.8% at a cost of 0.15–1.73 DKK per kg CO2 equivalent whereas the most effective scenario...

  9. Climate friendly technology transfer in the energy sector: A case study of Iran

    International Nuclear Information System (INIS)

    The energy sector is the biggest contributor of anthropogenic emissions of greenhouse gases into the atmosphere in Iran. However, abundant potential for implementing low-carbon technologies offers considerable emissions mitigation potential in this sector, and technology transfer is expected to play an important role in the widespread roll-out of these technologies. In the current work, globally existing low-carbon energy technologies that are compatible with the energy sector of Iran are identified and then prioritised against different criteria (i.e. Multi Criteria Decision Analysis). Results of technology prioritisation and a comprehensive literature review were then applied to conduct a SWOT analysis and develop a policy package aiming at facilitating the transfer of low carbon technologies to the country. Results of technology prioritisation suggest that the transport, oil and gas and electricity sectors are the highest priority sectors from technological needs perspective. In the policy package, while fuel price reform and environmental regulations are categorised as high priority policies, information campaigns and development of human resources are considered to have moderate effects on the process of technology transfer. - Highlights: • We examined the process of technology transfer in the energy sector of Iran. • Multi Criteria Decision Analysis techniques are used to prioritise the technological needs of the country. • Transportation, electricity and oil and gas sectors are found as recipients of new technologies. • A policy package was designed for facilitating technology transfer in the energy sector

    Wi, S.; Ray, P. A.; Brown, C.

    2015-12-01

    A software package developed to facilitate building distributed hydrologic models in a modular modeling system is presented. The software package provides a user-friendly graphical user interface that eases its practical use in water resources-related research and practice. The modular modeling system organizes the options available to users when assembling models according to the stages of hydrological cycle, such as potential evapotranspiration, soil moisture accounting, and snow/glacier melting processes. The software is intended to be a comprehensive tool that simplifies the task of developing, calibrating, validating, and using hydrologic models through the inclusion of intelligent automation to minimize user effort, and reduce opportunities for error. Processes so far automated include the definition of system boundaries (i.e., watershed delineation), climate and geographical input generation, and parameter calibration. Built-in post-processing toolkits greatly improve the functionality of the software as a decision support tool for water resources system management and planning. Example post-processing toolkits enable streamflow simulation at ungauged sites with predefined model parameters, and perform climate change risk assessment by means of the decision scaling approach.

    Full Text Available Let $G=(V,E$ be a connected simple graph. A labeling $f:Vrightarrow Z_2$ induces an edgelabeling $f^*:EtoZ_2$ defined by $f^*(xy=f(x+f(y$ for each $xy in E$. For $iinZ_2$,let $v_f(i=|f^{-1}(i|$ and $e_f(i=|f^{*-1}(i|$. A labeling $f$ is called friendly if$|v_f(1-v_f(0|le 1$. The full friendly index set of $G$ consists all possible differencesbetween the number of edges labeled by 1 and the number of edges labeled by 0. In recent years,full friendly index sets for certain graphs were studied, such as tori, grids $P_2times P_n$,and cylinders $C_mtimes P_n$ for some $n$ and $m$. In this paper we study the full friendlyindex sets of cylinder graphs $C_mtimes P_2$ for $mgeq 3$, $C_mtimes P_3$ for $mgeq 4$and $C_3times P_n$ for $ngeq 4$. The results in this paper complement the existing resultsin literature, so the full friendly index set of cylinder graphs are completely determined.

    The Advanced Hydropower Turbine System Program (AHTS) was created in 1994 by the U.S. Department of Energy, Electric Power Research Institute, and the Hydropower Research Foundation. The Program’s main goal is to develop “environmentally friendly” hydropower turbines. The Program’s first accomplishment was the development of conceptual designs of new environmentally friendly turbines. In order to do so, two contractors were competitively selected. The ARL/NREC team of engineers and biologists provided a conceptual design for a new turbine runner*. The new runner has the potential to generate hydroelectricity at close to 90% efficiency. The Voith team produced new fish-friendly design criteria for Kaplan and Francis turbines that can be incorporated in units during rehabilitation projects or in new hydroelectric facilities**. These include the use of advanced plant operation, minimum gap runners, placement of wicket gates behind stay vanes, among others. The Voith team will also provide design criteria on aerating Francis turbines to increase dissolved oxygen content. Detailed reviews of the available literature on fish mortality studies, causation of injuries to fish, and available biological design criteria that would assist in the design of fish-friendly turbines were performed. This review identified a need for more biological studies in order to develop performance criteria to assist turbine manufacturers in designing a more fish-friendly turbine.

    2013-01-01

    The need to use environmentally friendly technologies throughout future space-related launch programs prompted a study aimed at replacing current petroleum and solvent-based Corrosion Preventive Compounds (CPCs) with environmentally friendly alternatives. The work in this paper focused on the identification and evaluation of environmentally friendly CPCs for use in protecting flight hardware and ground support equipment from atmospheric corrosion. CPCs are used as temporary protective coatings and must survive in the aggressive coastal marine environment that exists throughout the Kennedy Space Center, Florida. The different protection behaviors of fifteen different oily film CPCs, both common petroleum-based and newer environmentally friendly types, were evaluated on various steel and aluminum substrates. CPC and substrate systems were subjected to atmospheric testing at the Kennedy Space Center's Beachside Atmospheric Corrosion Test Site, as well as cyclic accelerated corrosion testing. Each CPC also underwent physical characterization and launch-related compatibility testing. The results for the fifteen CPC systems are presented in this paper.

    Brendgen, Mara; Vitaro, Frank; Bukowski, William M; Dionne, Ginette; Tremblay, Richard E; Boivin, Michel

    2013-05-01

    The study examined whether reciprocal friendship quantity or quality can mitigate genetic vulnerability for depression symptoms in children. The sample comprised 168 monozygotic twin pairs and 126 same-sex dizygotic twin pairs assessed in Grade 4 (mean age = 10.04 years). Friendship participation was measured via reciprocal nominations of close friendships within the classroom. Friendship quality was measured through self-reports. Depression symptoms were measured through teacher and peer reports. Genetic vulnerability for depression symptoms was unrelated to friendship participation or the number of reciprocal friends, but it was negatively related to positive friendship quality. In line with gene-environment interaction, genetic risk effects on depression symptoms were mitigated in girls who had at least one close reciprocal friend. In boys, only moderate main effects of genetic vulnerability and friendship participation were found but no interaction between them. However, among boys with at least one reciprocal friend, a greater number of friends was related to fewer depression symptoms whereas no cumulative effect of friendship was found for girls. Finally, positive friendship quality was related to fewer depression symptoms in girls and boys even when controlling for genetic risk. The findings emphasize the importance of teaching social interactional skills that promote high-quality friendship relations to help prevent the development of depression symptoms in children.

    Landfill leachate is produced many years after a landfill site closes. Hence, treatment by “natural methods”, as e.g. constructed wetlands, with low management requirements is attractive. Constructed wetlands usually provide both shallow and deep areas with aerobic and anaerobic zones, which is suitable for nitrification followed by denitrification of the ammonium-rich leachates. Full-scale treatment systems are influenced by climatic variables that affect the microbial community. Also, the o...

  11. Development of a compact and user-friendly ion irradiation system controlled remotely through the internet

    International Nuclear Information System (INIS)

    A compact and user-friendly ion irradiation system controlled remotely through the Internet was developed for the execution of collaboration experiments together with researchers at remote sites. Several hardware instruments and software programs were constructed and provided for the remote control of the system and for its connection to the Internet. Surface modification and analysis experiments with this system were remotely performed through the Internet. It was confirmed from the experiments that the present ion irradiation system was precisely controlled through the Internet and could be easily and safely used for the surface modification and analysis, that the normal communication speed of around 10 Mbps for the Internet was fast enough for the execution of such typical remote-controlled experiments, and also that an access to the system by a mobile phone was convenient and useful enough to check the condition of the system and experimental data.

    Nakajima, Miyoshi; Iio, Shouichiro; Ikeda, Toshihiko

    The aim of this investigation is to develop an environmentally friendly nano-hydraulic turbine. Three type models of Savonius rotor are constructed and tested in a water tunnel to improve and clarify the power performance. Flow field around the rotor is examined visually to reveal the enhancement mechanisms of power coefficient using the double-step rotor. Flow visualization showed the difference of flow patterns at the central section between the standard (single-step) rotor and the double-step one. A meandering flow in the axial direction of the rotor was observed only for the double-step rotor. This flow had the pressure restoration effect at the returning blade's concave side and the torque strengthened effect at the advancing blade's convex side. As a consequence, the power coefficient was 10% improved.

    This essay, written by a statistician and a climate scientist, describes our view of the gap that exists between current practice in mainstream climate science, and the practical needs of policymakers charged with exploring possible interventions in the context of climate change. By `mainstream' we mean the type of climate science that dominates in universities and research centres, which we will term `academic' climate science, in contrast to `policy' climate science; aspects of this distinction will become clearer in what follows. In a nutshell, we do not think that academic climate science equips climate scientists to be as helpful as they might be, when involved in climate policy assessment. Partly, we attribute this to an over-investment in high resolution climate simulators, and partly to a culture that is uncomfortable with the inherently subjective nature of climate uncertainty.

  5. Putting Climate Change Adaptation in the Development Mainstream. Policy Brief

    International Nuclear Information System (INIS)

    Climate change poses a serious challenge to social and economic development. Developing countries are particularly vulnerable because their economies are generally more dependent on climate-sensitive natural resources, and because they are less able to cope with the impacts of climate change. How development occurs has implications, in turn, for climate change and for the vulnerability of societies to its impacts. Climate change adaptation needs to be brought into the mainstream of economic policies, development projects, and international aid efforts. Considerable analytical work has been done on how development can be made climate-friendly in terms of helping reduce greenhouse gas emissions which cause climate change, although implementation remains a challenge. Much less attention has been paid to how development can be made more resilient to the impacts of climate change. In a narrow engineering sense, this could involve taking climate changes into account in the siting and design of bridges and other infrastructure. At a policy level, it could involve considering the implications of climate change on a variety of development activities including poverty reduction, sectoral development, and natural resource management. Bridging the gap between the climate change adaptation and development communities, however, is not easy. The two communities have different priorities, often operate on different time and space scales, and do not necessarily 'speak the same language'. Specific information is therefore needed on the significance of climate change for development activities along with operational guidance on how best to adapt to its impacts, within the context of other pressing social priorities. This Policy Brief looks at how far current development policies and programmes are taking climate change risks into account, as well as at ways to improve the 'mainstreaming' of adaptation to climate change in development planning and assistance

  8. Environmentally-Friendly Geopolymeric Binders Made with Silica

    Science.gov (United States)

    Erdogan, S. T.

    2013-12-01

    Portland cement (PC) is the ubiquitous binding material for constructions works. It is a big contributor to global warming and climate change since its production is responsible for 5-10 % of all anthropogenic CO2 emissions. Half of this emission arises from the calcination of calcareous raw materials and half from kiln fuel burning and cement clinker grinding. Recently there have been efforts to develop alternative binders with lower greenhouse gas emissions. One such class of binders is geopolymers, formed by activating natural or waste materials with suitable alkaline or acidic solutions. These binders use natural or industrial waste raw materials with a very low CO2 footprint from grinding of the starting materials, and some from the production of the activating chemicals. The total CO2 emissions from carefully formulated mixtures can be as low as 1/10th - 1/5th of those of PC concrete mixtures with comparable properties. While use of industrial wastes as raw materials is environmentally preferable, the variability of their chemical compositions over time renders their use difficult. Use of natural materials depletes resources but can have more consistent properties and can be more easily accepted. Silica sand is a natural material containing very high amounts of quartz. Silica fume is a very fine waste from silicon metal production that is mostly non-crystalline silica. This study describes the use of sodium hydroxide and sodium silicate solutions to yield mortars with mechanical properties comparable to those of portland cement mortars and with better chemical and thermal durability. Strength gain is slower than with PC mixtures at room temperature but adequate ultimate strength can be achieved with curing at slightly elevated temperatures in less than 24 h. The consistency of the chemical compositions of these materials and their abundance in several large, developing countries makes silica attractive for producing sustainable concretes with reduced carbon

    2016-01-01

    This study tests the hypothesis that adolescents with romantic partners are less similar to their friends on rates of alcohol abuse than adolescents without romantic partners. Participants (662 girls, 574 boys) ranging in age from 12 to 19 years nominated friends and romantic partners, and completed a measure of alcohol abuse. In hierarchical linear models, friends with romantic partners were less similar on rates of alcohol abuse than friends without romantic partners, especially if they were older and less accepted. Follow-up longitudinal analyses were conducted on a subsample (266 boys, 374 girls) of adolescents who reported friendships that were stable across 2 consecutive years. Associations between friend reports of alcohol abuse declined after adolescents became involved in a romantic relationship, to the point at which they became more similar to their romantic partners than to their friends.

Results: A total of 236 women were included in the study. Of them, 196 (83.05%) were from baby-friendly hospitals and 40 (16.94%) from non-baby-friendly hospitals. Besides, 174 (88.7%) mothers in baby-friendly hospitals and 5 (12.5%) in non-baby-friendly hospitals during antenatal care received counseling by healthcare providers. There was an increase in breastfeeding practice up to 194 (98.97%) in the first category compared to 12 (30%) in the other category. Conclusion: Counseling under the Baby Friendly Hospital Initiative improved breastfeeding practices up to 98.97% in baby-friendly compared to non-baby-friendly hospitals. (author)

    Research efforts are under way to replace current corrosion inhibitors with more environmentally friendly alternatives. However, problems with corrosion inhibition efficiency, coating compatibility and solubility have hindered the use of many of these materials as simple pigment additives.This paper will present technical details on how the Corrosion Technology Lab at NASAs Kennedy Space Center (KSC) has addressed these issues by encapsulating environmentally friendly inhibitors into organic and inorganic microparticles and microcapsules. The synthetic process for polymer particles was characterized and post-synthesis analysis was performed to determine the interactions between the inhibitors and the encapsulation material. The pH-controlled release of inhibitors from various particle formulations in aqueous base was monitored and compared to both electrochemical and salt immersion accelerated corrosion experiment. Furthermore, synergistic corrosion inhibition effects observed during the corrosion testing of several inhibitor combinations will be presented.

    Breast feeding improves important outcomes for mothers and infants. In the UK, breastfeeding rates have historically been low, particularly among socially disadvantaged young women. Although there have been gradual increases in breastfeeding initiation rates since 2000, rates of exclusive breast feeding and continuation until 6 months remain lower than those in similar countries. This review summarises the evidence for effective and cost-effective strategies to help women, particularly those in low income groups, make informed choices, overcome barriers and establish and maintain breast feeding. We describe the development and impact of the Unicef Baby Friendly Initiative, and the roles and responsibilities, and challenges and opportunities that clinicians have in promoting breast feeding and maintaining a baby-friendly culture and environment.

    The continuing growth of aluminum alloy usage in transportation applications, notably passenger automobiles and minivans, and the demonstrated economic benefits of recycling aluminum-rich vehicles increase the need to seriously consider the desirability of designing recycling-friendly alloys. This article focuses on that aspect of the recycling process for passenger vehicles. The goals are to illustrate the opportunities afforded by identifying and taking full advantage of potential metal streams in guiding the development of new alloys that use those streams. In speculating on several possible aluminum recovery practices and systems that might be used in recycling passenger vehicles, likely compositions are identified and preliminary assessments of their usefulness for direct recycling are made. Specific compositions for possible new recycle-friendly alloys are suggested. In addition, recommendations on how the aluminum enterprise, including industry, academia, and government, can work together to achieve the aggressive but important goals described here are discussed.
