    Full Text Available Cattle rearing generate more global warming green house gases than driving cars. These green house gases leads to changes in the climate. This climate change affects the livestock, man and natural environment continuously. For this reason it is important for livestock farmers to find the ways which minimize these gases emission. In this article the causes of climate change and effects, measures to be taken by farmers and their efficiency in reducing green house gases emission were reviewed briefly to make the farmers and students aware of the reduction of global warming green house gases and measures to be taken for reducing these gases.

    This paper analyzes the cost-effectiveness in the mitigation of green house gases from solar, eolic and nuclear energy sources, concluding that nuclear is, not doubt, the mos efficient. On the other hand, nuclear is the unique source that can be installed without limit in magnitude and in the proximity of the demand, and is for all these reasons that several environmental referents in the world have changed their perception on this source and defend it as the unique actual alternative to fight against the emission of green house gases.

    Colombia when signing the agreement mark of the united nations for the global change in 1992 and to ratify it in 1996 committed, together with the other signatory countries, to elaborate and to publish national inventories of anthropogenic emissions of green house gases and plans for its reduction and control. In this reference mark a group of professionals inside the Colombian academy of exact, physical and natural sciences, began in July of 1995, the national inventory of greenhouse gases for Colombia, having the approval of the ministry of the environment, the financial support of the organization of German technical cooperation GTZ and the technical consultantship of the work group that it is carrying out the study in the case of Venezuela. This article presents a summary of the results of the project, making emphasis in the main anthropogenic activities responsible for these emissions, especially those related with the energetic sector

    Greenhouse gases (GHGs) are a major cause of global warming. While food waste composting can reduce the amount of waste being sent to traditional landfills, it also produces GHGs during the process. The objective of this research is to evaluate the GHGs emitted from an aerobic food composting machine, which is used in ISF. The Independent Schools Foundation Academy is a private independent school in Hong Kong with approximately 1500 students. Each academic year, the school produces 27 metric tons of food waste. In November 2013, the school installed a food waste composting system. Over the past 3 years, various improvements, such as installing a bio-filter to reduce the smell of the compost, have been made to the composting process. Meanwhile the compost is used by the primary students, as part of their experiential learning curriculum and organic farming projects. The composting process employs two machines: the Dehydra and A900 Rocket. The Dehydra reduces the mass of the food waste by separating the ground food waste and excessive water. The A900 Rocket, a composter made by Tidy Planet, processes food waste into compost in 14 days. This machine runs in an aerobic process, in which oxygen is used as an input gas and gases, such as carbon dioxide, are released. Carbon Dioxide is one of the greenhouse gases (GHGs). This research focuses on GHGs that are emitted from the A900 Rocket. The data is collected by the Gasmet DX 4015, a Fourier transform infrared spectroscopy (FTIR) multi gas analyser. This equipment measures the concentration (ppm) of different GHGs, including N2O, CO2, CH4, NH3 and CO.

    The objectives of the project was to develop technologies by which the flue gases from burning bio fuels and peat can be purified for used in green houses as a low cost source of carbon dioxide. Traditionally carbon dioxide has been produced by burning propane or natural gas or by injecting bottled carbon dioxide gas directly into the green house. The new methods should be more affordable than the present ones. The flue gases from burning wood and peat need cleaning, because they contain substances that are harmful to plants. Also the food use of the plants may cause additional restrictions. Harmful substances are e.g. the nitrogen oxides, sulphur compounds and heavy metals. The most complex ones are the nitrogen oxides, as they cannot be sufficiently removed by traditional cleaning methods. A pilot plant was designed for testing the influence of with new methods cleaned combustion gases on commercially important crops. The project has started 01.04.2005 and was ended 30.06.2006. During the project time, commercial solutions were in construction, thus the pilot plant was decided to be built when the commercial application had been taken in use. (orig.)

    CFCs (halogenated chlorofluorocarbons), HCFCs (hydrochlorofluorocarbons), HFCs (hydrofluorocarbons), PFCs (fluorocarbons) and SF{sub 6} (sulphur hexafluoride) are all artificial substances which were not to be found in nature until recently. In 1995 the Danish consumption of HFC substances was approximately 740 tonnes, where the corresponding amount of SF{sub 6} was about 17 tonnes. If the entire amount of these substances was released to to the atmosphere, the resulting impact would correspond to an increased emission of greenhouse gases, corresponding to approximately 1.5 million tonnes of CO{sub 2}. HFC substances would account for 73%, SF{sub 6} with 25% and PFC for 1%. This corresponds to approximately 2.6% of the Danish CO{sub 2} emission (nearly 60 million tonnes per year). This corresponds to about half of the aimed 6% reduction of CO{sub 2} emission attained by introduction of mandatory green taxes on CO{sub 2}. According to experience from the CFC programme it is possible to recover some CFC and send it to controlled destruction. From 1993 to 1996 the refrigeration industry, for instance, has returned a total amount of 163 tonnes of CFC refrigerant through the KMO organization (Koelebranchens Miljoe Ordning). Most of this has been destroyed and a small amount has been purified and recycled afterwards. Similarly, it is likely to believe that some HFC refrigerant will be returned through the KMO organization. (au) 11 refs., also published in Danish

  8. Opportunities and challenges in green house gases reduction using high pressure direct injection of natural gas

    Ouellette, P.

    2001-01-01

    In an effort to reduce Greenhouse Gases, Westport Innovations is developing a high pressure direct injection (HPDI) technology for gaseous fuels. This technology adapts the diesel cycle for gaseous fuels, since the diesel cycle provides high efficiency, high low-speed torque, fast transient capabilities and reliability. Because of their high efficiency, diesels are very favorable from a Greenhouse Gas (GHG) point of view, however they remain challenged by high nitrogen oxides (NOx) and particulate matter (PM) emissions. When directly injecting natural gas, NOx and PM emissions can be reduced by approximately 50% while maintaining the performance of the diesel engine. This allows the use of abundant and historically cheaper natural gas. Because of its lower carbon content per unit energy, natural gas also offers further GHG reduction over the diesel if the efficiency is preserved and if methane emissions are low. This paper discusses development efforts at Westport for several applications including on-highway trucks, light-duty delivery trucks and power generation

  9. INVENTORY OF GREEN HOUSE GASES AND OTHER POLLUTANTS FROM THE TRANSPORT SECTOR: DELHI

    Full Text Available Delhi is the most urbanized city in India. Inventory estimates for the emissions of greenhouse gases and other pollutants like CO2, CO, NOx, and volatile organic compound from transport sector in Delhi, has been developed using bottom up approach provided by Intergovernmental panel on climate change (IPCC-1996. The impacts of policy option in transport sector like introduction of Compressed Natural Gas for public transport in Delhi and introduction of Euro-1 norms for vehicles have also been estimated. The emission inventory reveals that total emission of pollutants from different categories vehicles have increased during the period 1990-2000. For example, the CO2 emission (1000, tones from gasoline driven vehicle (MC/SC in Delhi has increased from 766 in 1990-91 to 1187 in 1999-00. The diesel driven vehicles Light commercial vehicles in Delhi has contributed to 577 CO2 in 1990-91, which increased to 9779 in 1999-00. For other pollutants also, which have been estimated here, an increase in total emission from gasoline and diesel driven vehicles has been observed during this 1990-2000 periods. This study shows that the over all contribution of pollutants in the total emissions from gasoline and diesel driven vehicles have increased in Delhi during this period. The present study also shows that the implementation of Euro-1 in 2000 in Delhi has resulted in the decrease of total emission of CO, HC, NOx, and volatile organic compound for all the classes of vehicle for which the revised vehicle emissions norms were implemented. However this decrease in emission has become inefficient due to increase in vehicle population.

    Full Text Available The Green Core House is a construction concept with low environmental impact, having as main central element a greenhouse. The greenhouse has the innovative role to use the biomass energy provided by plants to save energy. Although it is the central piece, the greenhouse is not the most innovative part of the Green Core House, but the whole building ensemble because it integrates many other sustainable systems as "waste purification systems", "transparent photovoltaic panels" or "double skin façades".

  11. Physical Absorption of Green House Gases in Amines: The Influence of Functionality, Structure, and Cross-Interactions.

    Monte Carlo simulations were performed in the isothermal-isobaric ensemble (NPT) to calculate the Henry constants of methane (CH 4 ), nitrous oxide (N 2 O), and carbon dioxide (CO 2 ) in pure H 2 O, amines, and alkanolamines using the classical Lorentz-Berthelot combining rules (L-B). The Henry constants of N 2 O and CO 2 in water are highly overestimated and motivated us to propose a new set of unlike interactions. Contrarily, the Henry constant of N 2 O in MEA is underestimated by around 40%, and again, a new reoptimized cross unlike parameter is able to reproduce the constant to within 10%. An analysis is given of the relationship between the physical absorption of these gases and the chemical structure or functionality of 12 molecules including amines and alkanolamines using the anisotropic united atom intermolecular potential (AUA4). Finally, the solubility of N 2 O in an aqueous solution of monoethanolamine (MEA) at 30% (wt) was also studied. A Henry constant within 7% of the experimental value was found by using the reoptimized parameters along with L-B to account for the MEA + H 2 O unlike interactions. This very good agreement without additional adjustments for the MEA + H 2 O system may be attributed to the good excess properties predictions found in previous works for the binary mixture (MEA + H 2 O). However, further work, including additional alkanolamines in aqueous solutions at several concentrations, is required to verify this particular point.

    In this study, methane (CH{sub 4}) and nitrous oxide (N{sub 2}O) emission dynamics of a plug–flow bioreactor located in a municipal full-scale wastewater treatment plant were monitored during a period of 10 weeks. In general, CH{sub 4} and N{sub 2}O gas emissions from the bioreactor accounted for 0.016% of the influent chemical oxygen demand (COD) and 0.116% of the influent total Kjeldahl nitrogen (TKN) respectively. In order to identify the emission patterns in the different zones, the bioreactor was divided in six different sampling sites and the gas collection hood was placed for a period of 2–3 days in each of these sites. This sampling strategy also allowed the identification of different process perturbations leading to CH{sub 4} or N{sub 2}O peak emissions. CH{sub 4} emissions mainly occurred in the first aerated site, and were mostly related with the influent and reject wastewater flows entering the bioreactor. On the other hand, N{sub 2}O emissions were given along all the aerated parts of the bioreactor and were strongly dependant on the occurrence of process disturbances such as periods of no aeration or nitrification instability. Dissolved CH{sub 4} and N{sub 2}O concentrations were monitored in the bioreactor and in other parts of the plant, as a contribution for the better understanding of the transport of these greenhouse gases across the different stages of the treatment system. - Highlights: • Monitoring of CH{sub 4} and N{sub 2}O emissions from a full-scale activated sludge bioreactor • Process perturbations leading to CH{sub 4} and N{sub 2}O peak emissions were identified. • Peak emissions increased severely the overall emission account of the bioreactor. • CH{sub 4} emissions were related with the inflow of influent and reject wastewater. • N{sub 2}O was generated as consequence of nitrification imbalances.

    In the last years much attention has been given to the polluting gas discharges, in special of those that favor the green house effect (GHE), due to the negative sequels that its concentration causes to the atmosphere, particularly as the cause of the increase in the overall temperature of the planet, which has been denominated world-wide climatic change. There are many activities that allow to lessen or to elude the GHE gas emissions, and with the main ones the so-called projects of Energy Efficiency and Renewable Energy (EE/RE) have been structured. In order to carry out a project within the frame of the MDL, it is necessary to evaluate with quality, precision and transparency, the amount of emissions of GHE gases that are reduced or suppressed thanks to their application. For that reason, in our country we tried different methodologies directed to estimate the CO{sub 2} emissions that are attenuated or eliminated by means of the application of EE/RE projects. [Spanish] En los ultimos anos se ha puesto mucha atencion a las emisiones de gases contaminantes, en especial de los que favorecen el efecto invernadero (GEI), debido a las secuelas negativas que su concentracion ocasiona a la atmosfera, particularmente como causante del aumento en la temperatura general del planeta, en lo que se ha denominado cambio climatico mundial. Existen muchas actividades que permiten aminorar o eludir las emisiones de GEI, y con las principales se han estructurado los llamados proyectos de eficiencia energetica y energia renovables (EE/ER). Para llevar a cabo un proyecto dentro del marco del MDL, es necesario evaluar con calidad, precision y transparencia, la cantidad de emisiones de GEI que se reducen o suprimen gracias a su aplicacion. Por ello, en nuestro pais ensayamos diferentes metodologias encaminadas a estimar las emisiones de CO{sub 2} que se atenuan o eliminan mediante la aplicacion de proyectos de EE/ER.

    In cooperation with the Triodos Bank, SEV carried out a study on the possibility to invest money from green investment funds at low interest in houses which are designed and built in a sustainable and energy efficient way. By order of the Triodos Bank and SEV others drafted a guideline to assess dwellings and calculated the financial and economical consequences of green investments in sustainable housing. The results of those studies formed the basis of the SEV recommendation to the Dutch State Secretary of Housing and Planning and the Dutch State Secretary of Economic Affairs, April 1996, to expand the planned Green Investment Regulation to the possibility to invest money in sustainable houses. It is expected that the Green Investment Regulation will come into effect September 1996. 2 appendices

    Full Text Available In the United States, two thirds of the carbon monoxide and about one third of carbon dioxide emissions come from the transportation sector. Ways to reduce these emissions in the future include replacing gasoline and diesel by biofuels, or by blend of biofuels with conventional gasoline and diesel, or by compressed natural gas (CNG, or by replacing internal combustion engines by electric motors powered by hydrogen fuel cells or battery-powered electric vehicles recharged from the electric grid. This presentation will review these technologies the fuel production pathways, when they are likely to be available, and by what fraction transportation sector green house gas emissions could be reduced by each. A well-to-wheels (WTW analysis is performed on each vehicle/ fuel technology using the GREET model and the total energy use, the CO 2 emissions, NO x emissions, SO x emissions for the life cycle of the vehicle technologies are calculated. Prospects for reducing foreign oil dependence as well as mitigating green house gases emission from the transportation sector will be considered in the analysis.

    Full Text Available Green building has been adopted and became an accepted norm in the developed countries like USA, UK, Canada and Australia. Despite the good efforts shown by the developed countries on how to build green building, the developing and less developed countries inclusive Malaysia seem lag behind in this aspect. The issue of sustainable approach in building industry in Malaysia is still new and there are a little of housing projects are meeting the criteria of green buildings. The housing developers are exposed to the risk of uncertainty demand from the house buyers if they are interested to develop green homes. This paper discuss the development of concept and design of green homes by using product development process model in the manufacturing and building industry in order to assist the housing developers to reduce the risk associated with this new product such this green homes.

  20. Economising subsidies for green housing features: A stated preference approach

    2014-12-01

    Full Text Available In light of the enormous amounts of energy and resources consumed by housing development and operations, many governments have started recognising the urgent need to promote green or eco-friendly housing with the aim of achieving sustainable development. Apart from regulations, governments can offer incentives to developers to provide green features in their developments by offering subsidies in various forms. However, such subsidisation is often uneconomical. In theory, market forces can lead to green housing provision without any government intervention if the market players are willing to pay extra for the green features of housing. Against this background, this article presents the findings of a study that compared potential homebuyers’ willingness to pay (WTP for various green housing features based on findings from a structured questionnaire survey in Macau. The housing attributes under investigation included uses of green materials (e.g., sustainable forest products and construction methods (e.g., prefabrication, energy-efficient technologies (e.g., LED lighting and water-saving devices (e.g., grey-water recycling systems. Results indicate that the respondents’ WTP was mainly motivated by economic incentives. Green housing attributes that can offer direct financial benefits corresponded to greater WTP. The policy implications of the research findings then follow.

    To evaluate the impact of the Green House (GH) model on nursing home resident-level quality of care measures. Resident-level minimum data set (MDS) assessments merged with Medicare inpatient claims for the period 2005 through 2010. Using a difference-in-differences framework, we compared changes in care quality and outcomes in 15 nursing homes that adopted the GH model relative to changes over the same time period in 223 matched nursing homes that had not adopted the GH model. For individuals residing in GH homes, adoption of the model lowered readmissions and several MDS measures of poor quality, including bedfast residents, catheter use, and pressure ulcers, but these results were not present across the entire GH organization, suggesting possible offsetting effects for residents of non-GH "legacy" units within the GH organization. GH adoption led to improvement in rehospitalizations and certain nursing home quality measures for individuals residing in a GH home. The absence of evidence of a decline in other clinical quality measures in GH nursing homes should reassure anyone concerned that GH might have sacrificed clinical quality for improved quality of life. © Health Research and Educational Trust.

    Extracts of neem (Azadirachta indica A. Juss.) and Gliricidia sepium Jacquin, locally known as 'mata-raton', are used to control pests of maize. Their application, however, is known to affect soil microorganisms. We investigated if these extracts affected emissions of methane (CH4), carbon dioxide (CO2) and nitrous oxide (N2O), important greenhouse gases, and dynamics of soil inorganic N. Soil was treated with extracts of neem, mata-raton or lambda-cyhalothrin, used as chemical control. The soil was amended with or without urea and incubated at 40% and 100% water holding capacity (WHC). Concentrations of ammonium (NH4+), nitrite (NO2(-)) and nitrate (NO3(-)) and emissions of CH4, CO2 and N2O were monitored for 7d. Treating urea-amended soil with extracts of neem, mata-raton or lambda-cyhalothrin reduced the emission of CO2 significantly compared to the untreated soil with the largest decrease found in the latter. Oxidation of CH4 was inhibited by extracts of neem in the unamended soil, and by neem, mata-raton and lambda-cyhalothrin in the urea-amended soil compared to the untreated soil. Neem, mata-raton and lambda-cyhalothrin reduced the N2O emission from the unamended soil incubated at 40%WHC compared to the untreated soil. Extracts of neem, mata-raton and lambda-cyhalothrin had no significant effect on dynamics of NH4(+), NO2(-) and NO(3)(-). It was found that emission of CO2 and oxidation of CH4 was inhibited in the urea-amended soil treated with extracts of neem, mata-raton and lambda-cyhalothrin, but ammonification, N2O emission and nitrification were not affected.

    Inland waters (streams, rivers, lakes, reservoirs) are quantitatively important components of the global budgets of atmospheric emissions of long-lived greenhouse gases (GHGs) (CO2, CH4, N2O). Available data indicate that a very large fraction of CO2 and CH4 emissions from rivers and reservoirs occurs at tropical latitudes. Data on GHGs at tropical latitudes from lakes however are much more scarse, and the relative importance of emissions, in particular in Africa, remains to be determined. Large tropical lakes are net autotrophic (hence potentially sinks for atmospheric CO2) due generally low dissolved organic carbon concentrations, seasonally near constant light and temperature conditions, and generally deep water columns favourable for export of organic matter to depth. This sharply contrasts with their much better documented temperate and boreal counterparts, usually considered as CO2 sources to the atmosphere sustained by net heterotrophy. Here, we report a data-set of dissolved CO2, CH4, N2O obtained in October 2016 in Lakes Edward and George and adjacent streams and crater lakes in the frame of Belgian Science Policy (BELSPO) HIPE (Human impacts on ecosystem health and resources of Lake Edward, http://www.co2.ulg.ac.be/hipe/) project. Lake George and part of Lake Edward were sinks for atmospheric CO2 and N2O due to high primary production and denitrification in sediments, respectively, and modest sources of CH4 to the atmosphere. Sampled rivers and streams were oversaturated in CO2 and CH4 and close to atmospheric equilibrium with regards to N2O. Spatial variations within rivers and streams were related to elevation and vegetation characteristics on the catchments (savannah versus forest). Levels of CO2, CH4, and N2O were within the range of those we reported in other African rivers. Crater lakes acted as sinks for atmospheric CO2 and N2O but were extremely over-saturated in CH4, due to intense primary production sustained by cyanobacteria. These CH4 levels

The aims of this study are: (1) to evaluate and recommend an optimum Urban Green Space (UGS) area for the Bangkok Metropolitan Administration (BMA); and (2) to quantify potential renewable resources including electricity generation and potential nutrient recovery from generated ash. Green House Gases (GHGs) emissions from the management of Green Residues (GR) produced in a recommended UGS expansion are estimated and compared with those from the existing BMA waste management practice. Results obtained from this study indicate that an increase in UGS from its current 2.02% to 22.4% of the BMA urban area is recommended. This optimum value is primarily due to the area needed as living space for its population. At this scale, GR produced of about 334kt·y -1 may be used to generate electricity at the rate of 206GWh·y -1 by employing incineration technology. Additionally, instead of going to landfill, phosphorus (P) contained in the ash of 1077 t P·y -1 could be recovered to produce P fertilizer to be recycled for agricultural cultivation. Income earned from selling these products is found to offset all of the operational cost of the proposed GR management methodology itself plus 7% of the cost of BMA's Municipal Solid Waste (MSW) operations. About 70% of the current GHGs emission may be reduced based on incineration simulation. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Agricultural animal production in increasingly regarded as a source of gases which are both aggravating and ecologically harmful. An overview of the origin, number and quantity of trace gases emitted from animal housing and from manure stores is presented and possible means of preventing or reducing them are discussed. Of the 136 trace gases in the air of animal houses, odorous substances, ammonia and methane are most relevant to the environment. The role played by the remaining gases is largely unknown. Quantitative information is available for 23 gases. The gases are emitted principally from freshly deposited and stored faeces, from animal feed and from the animals themselves. Future work should determine sources and quantities of the gases emitted from animal housing more precisely and should aim to investigate the potential of these gases to cause damage in man, animals and environment. Odorous substances have an effect on the area immediately surrounding the animal housing. They can lead to considerable aggravation in humans. For years, VDI1 guidelines (3471/72), which prescribe distances between residential buildings and animal housing, have been valuable in preventing odour problems of this kind. Coverings are suitable for outside stores. The intensity of the odour from animal housing waste air increases from cattle through to hens and pigs; it is also further affected by the type of housing, the age of the animals and the purpose for which they are being kept. Methods of cleaning waste air (scrubbers/biofilters) are available for problematic cases. The need for guidelines to limit emissions from individual outside manure stores (lagoons) is recognised. Total ammonia emissions from animal production in the Federal Republic of Germany (up to 1989) are estimated at approximately 300,000 to 600,000 t/year. There is a shortage of satisfactory and precise research on the extent of emissions, in particular on those from naturally ventilated housing. It is

    Full Text Available The issues of energy crisis, environmental degradation, and climate change present a severe challenge to the sustainable development in China. The development of green building (GB is considered one of the most popular strategies toward a sustainable construction industry. Apart from advanced green technologies, consumers’ purchasing intention toward green housing (GH plays a crucial role in the large-scale promotion of GB. However, which determinants significantly affect consumers’ purchasing intention remain unclear, especially for the young generation in developing countries. This study attempts to investigate young consumers’ purchasing intention of GH in China. On the basis of extended theory of planned behavior (TPB, seven constructs are identified, and nine hypotheses are proposed. A total of 241 responses were collected from the questionnaire survey, and structural equation modeling was employed to test the proposed hypotheses. Governmental incentives are affirmed to be the most important determinant, followed by consumers’ attitude toward behavior and subjective norm. Perceived behavioral control is an insignificant determinant for young consumers to purchase GH. In addition, subjective knowledge has an indirect effect through attitude toward behavior. Environmental concern also confirms an indirect effect through attitude toward behavior and subjective norm toward purchasing intention, respectively. Thus, the government is implied to play a crucial role in GH promotion at this stage.

    Full Text Available The occurrence of airborne dust, gases, microbes, endotoxin and bovine epithelial antigens (BEA, BDA20 was studied in 26 modern, mainly cubicle, cow houses. Air samples of total dust, total spores, endotoxin and bovine epithelial allergens were collected on membrane filters with portable or piston pumps and analyzed with appropriate methods. Concentrations of gases (ammonia, carbon dioxide, hydrogen sulfide were measured with diffusion tubes. Airborne viable spores were collected with a cascade impactor on five selective culture media for the identification of xerophilic, mesophilic and thermotolerant fungi and thermophilic actinomycetes. The geometric mean concentrations of total dust, BEA and BDA20 were 0.2-1.9 mg/m 3 , 5.2- 9.7 mg/m 3 and 50-260 ng/m 3 , respectively. The mean concentrations of ammonia and carbon dioxide were between 2.8-15 ppm and 2200-3200 ppm, respectively. The geometric mean of endotoxins was 19 ng/m 3 and the concentrations of fungi were at the 10 1 -10 3 cfu/m 3 level. In general, the variation in concentrations of total dust, viable fungi and endotoxin was large. The concentrations of total dust and fungi were lower than in earlier studies. Thus new cubicle houses provide a better working environment with regard to airborne hazards than the traditional cow houses.;

    Detailed studies of Apollo 15 green glass and related beads have shown they were formed in gas-rich fire fountains.. As the magmatic fluid became super-saturated in volatile gas, bubbles or vesicles formed within the magma. These exsolved gases became trapped within vesicles as the glasses were ejected from the fire-fountain and subsequently quenched. One of the keys to understanding formation processes on the ancient moon includes determining the composition of volatile species and elements, including metals, dissolved in magmatic gases. Here we report the nature of mineral phases spatially associated with vesicles in a green glass bead from Apollo sample 15411,42. The phases reflect the composition of the cooling/degassing magmatic vapors and fluids present at the time of bead formation approx, 3 Ga ago

    Full Text Available Important green house gases (GHG attributed to animal agriculture are methane (CH4 and nitrous oxide (N2O, though carbon dioxide (CO2 contributes almost half of total greenhouse effect. Rumen CH4 production in an enteric fermentation can be accounted as the biggest anthropogenic source. Some of prebiotics and probiotics have been innovated to mitigate rumen CH4 emission. The possible use of agricultural biomass consisted of non-edible parts of crop plants such as cellulose and hemi cellulose and animal wastes was proposed as a renewable energy and nitrogen sources. The ammonia stripping from digested slurry of animal manure in biogas plant applied three options of nitrogen recycling to mitigate nitrous oxide emission. In the first option of the ammonia stripping, the effect of ammonolysis on feed value of cellulose biomass was evaluated on digestibility, energy metabolism and protein utilization. Saccharification of the NH3 treated cellulose biomass was confirmed in strictly anaerobic incubation with rumen cellulolytic bacteria, Ruminoccous flavefaciens, to produce bio-ethanol as the second option of ammonia stripping. In an attempt of NH3 fuel cell, the reformed hydrogen from the NH3 stripped from 20 liter of digested slurry in thermophilic biogas plant could generate 0.12 W electricity with proton exchange membrane fuel cell (PEM as the third option.

    High latitude boreal peatlands contribute importantly to the land-atmosphere-hydrosphere exchange of carbon and GHG, i.e. carbon dioxide, methane and dissolved organic carbon. High latitude biomes are identified as most vulnerable to changing climate. High latitudes are also characterized by a strong seasonality in incoming solar radiation, weather conditions and thus also in biogeochemical processes. The strong seasonality in incoming solar radiation, not to change in response to a changing climate, constitute firm constraints on how changes in air temperature, evapotranspiration and precipitation will affect biogeochemical processes underlying the land atmosphere and land hydrosphere exchange of green house gases. In this presentation I combine data from long-term monitoring, long-term field manipulations and detailed chemical analysis to understand how changes in atmosphere and weather conditions influence the major carbon fluxes of a boreal mire Net Ecosystem Carbon Balance. The long-term monitoring data contains >12 years of continuous Eddy Covariance CO2 data, growing season chamber CH4 data and continuous measurements of discharge export of DOC, CO2 and CH4. Data from long-term field snow removal manipulations and growing season temperature increase manipulations are used to further understand the impact of climate on mire carbon and GHG fluxes. Finally we uses Nuclear Magnetic Spectroscopy (NMR) to reveal how century scale changes in atmospheric CO2 from 300 to 400 pm CO2 and temperature have influenced the net photosynthetic capacity of Sphagnum mosses, the single most important plant genus for boreal mire carbon sequestration.

    An adult, male, wild-caught, laboratory-housed green anole (Anolis carolinensis) on a locomotor performance study was presented for anorexia. The anole exhibited a 26% weight loss and a thin body condition but was otherwise alert and active. Despite supportive care, the anole's clinical condition deteriorated, necessitating euthanasia. Postmortem examination revealed a 4.5 mm × 2.5-mm cystic calculus, which consisted entirely of sodium urate. Here we describe the clinical findings and locomotor consequences of this disease in a green anole. Although urolithiasis has been reported clinically in reptiles, this report presents the first case of a cystic calculus in a laboratory-housed green anole.

  3. Design strategies for integration of green roofs in sustainable housing

    2015-12-01

    Full Text Available Green roofs are the integration of plant material and its supporting structures in buildings. Such an approach provides a habitat for local flora and fauna, helps manage storm water, reduces heat demand in winter and the cooling load in the summer, enhances the aesthetic values of dwellings, provides the occupants with comfort and amenities and strengthens environmental responsibility. Because roofs represent approximately 40 percent to 50 percent of the surfaces in urban areas, green roofs have an important role in drainage and as a result water management as well. In fact, when a green roof is installed on 50 percent or more of the roof’s surface, it guarantees 2 points and can contribute 7 additional points toward LEED certification - almost 20 percent of the required rating. This paper classifies green roofs and offers strategies for their integration in residential buildings and examines their benefits, construction principles and applications.

    Transition to environmentally friendly technologies provides a comprehensive solution to problem of creating an economic value without destroying the nature. Buildings using green technologies lead to lower operating costs, healthier living and working environment and protect the environment more. The aim of this paper is to assess the environmental impact of two alternatives of family house designed as conventional building and building with green technologies. Evaluated family house are located in village Kokšov Bakša, which is situated 12 km south-east from city of Košice, a metropolis of eastern Slovakia. This analysis investigates the role of applied green technologies in single family houses for impact categories: global warming potential (GWP), acidification potential (AP) and eutrophication potential (EP) expressed as CO2eq, SO2eq and PO4 3- eq within “Cradle to Grave” boundary by using the LCA assessment method. The main contribution of the study is a proof that green technologies have significant part in the reduction of environmental impacts. Results show that alternative of family house designed as green one contributes to CO2eq, SO2eq and PO4 3- eq emissions by 81%, 73% and 35% less than alternative of conventional family house, respectively.

    To systematically manage the energy consumption of existing buildings, the government has to enforce greenhouse gas reduction policies. However, most of the policies are not properly executed because they do not consider various factors from the urban level perspective. Therefore, this study aimed to conduct a dynamic analysis of an urban-based low-carbon policy using system dynamics, with a specific focus on housing and green space. This study was conducted in the following steps: (i) establishing the variables of urban-based greenhouse gases (GHGs) emissions; (ii) creating a stock/flow diagram of urban-based GHGs emissions; (iii) conducting an information analysis using the system dynamics; and (iv) proposing the urban-based low-carbon policy. If a combined energy policy that uses the housing sector (30%) and the green space sector (30%) at the same time is implemented, 2020 CO{sub 2} emissions will be 7.23 million tons (i.e., 30.48% below 2020 business-as-usual), achieving the national carbon emissions reduction target (26.9%). The results of this study could contribute to managing and improving the fundamentals of the urban-based low-carbon policies to reduce greenhouse gas emissions.

    Monsoon water cycle is the lifeline to over 60 per cent of the world's population. Throughout history, the monsoon-related calamities of droughts and floods have determined the life pattern of people. The association of Green House Gases (GHGs) particularly Carbon dioxide (CO2) with monsoon has been greatly debated amongst the scientific community in the past. The effect of CO2 on the monsoon rainfall over the Indian-Indonesian region (8-30°N, 65°-100°E) is being investigated using satellite data. The correlation coefficient (Rxy) between CO2 and monsoon is analysed. The Rxy is not significantly positive over a greater part of the study region, except a few regions. The inter-annual anomalies of CO2 is identified for playing a secondary role to influencing monsoon while other phenomenon like ENSO might be exerting a much greater influence.

    We examined associations of several health outcomes with green and conventional low-income housing, where the prevalence of morbidities and environmental pollutants is elevated. We used questionnaires and a visual inspection to compare sick building syndrome (SBS) symptoms and asthma-related morbidity among residents in multifamily units in Boston, Massachusetts, between March 2012 and May 2013. Follow-up was approximately 1 year later. Adults living in green units reported 1.35 (95% confidence interval [CI] = 0.66, 2.05) fewer SBS symptoms than those living in conventional (control) homes (P green homes experienced substantially lower risk of asthma symptoms (odds ratio [OR] = 0.34; 95% CI = 0.12, 1.00), asthma attacks (OR = 0.31; 95% CI = 0.11, 0.88), hospital visits (OR = 0.24; 95% CI = 0.06, 0.88), and asthma-related school absences (OR = 0.21; 95% CI = 0.06, 0.74) than children living in conventional public housing. Participants living in green homes had improved health outcomes, which remained consistent over the study period. Green housing may provide a significant value in resource-poor settings where green construction or renovation could simultaneously reduce harmful indoor exposures, promote resident health, and reduce operational costs.

    Growing attention in the past few decades has focused on improving care quality and quality of life for nursing home residents. Many traditional nursing homes have attempted to transform themselves to become more homelike emphasizing individualized care. This trend is referred to as nursing home culture change in the U.S. A promising culture change nursing home model, the Green House nursing home model, has shown positive psychological outcomes. However, little is known about whether the Green House nursing home model has positive effects on physical function compared to traditional nursing homes. To examine the longitudinal effects of the Green House nursing home model by comparing change patterns of activities of daily living function over time between Green House home residents and traditional nursing home residents. A retrospective longitudinal study. Four Green House organizations (nine Green House units and four traditional units). A total of 242 residents (93 Green House residents and 149 traditional home residents) who had stayed in the nursing home at least 6 months from admission. The outcome was activities of daily living function, and the main independent variable was the facility type in which the resident stayed: a Green House or traditional unit. Age, gender, comorbidity score, cognitive function, and depressive symptoms at baseline were controlled. All of these measures were from a minimum dataset. Growth curve modeling and growth mixture modeling were employed in this study for longitudinal analyses. The mean activities of daily living function showed deterioration over time, and the rates of deterioration between Green House and traditional home residents were not different over time. Four different activities of daily living function trajectories were identified for 18 months, but there was no statistical difference in the likelihood of being in one of the four trajectory classes between the two groups. Although Green House nursing homes are

    Full Text Available The United Nations has designated the year 2012 as the international year of sustainable energy. Today, we are seeing a rise in global awareness of energy consumption and environmental problems. Many nations have launched different programs to reduce the energy consumption in residential and commercial buildings to seek lower-carbon energy solutions. We are talking about the future green and smart houses. The subject of smart/green houses is not one of “why,” but rather “how,” specifically: “how making the future house more energy efficient.” The use of the renewable energy, the technology and the services could help us to answer this question. Intelligent home energy management is an approach to build centralized systems that deliver application functionality as services to end-consumer applications. The objective of this work is to develop a smart and robust controller for house energy consumption with maximizing the use of solar energy and reducing the impact on the power grid while satisfying the energy demand of house appliances. We proposed a fuzzy-based energy management controller in order to reduce the consumed energy of the building while respecting a fixed comfort.

    Green areas have always been an essential feature of urban developments, improving the quality of life within a community, both from a social perspective - offering residents a place for relaxation and interaction, as well as from the point of view of disease prevention - improving the overall air quality, but also encouraging inhabitants to spend more time outside. The importance of these areas within a settlement further increases in the present-day context, in which the constant expansion of cities in their surrounding territory, phenomenon known as “urban sprawl”, gradually eliminates the natural green spaces and agricultural terrains from our landscape. This trend has devastating effects on the environment, as well as on the micro-climate of our settlements, characterized, in recent years, by the formation of heat islands within the built tissue. Moreover, the disappearance of natural green areas leads to the constant estrangement of the inhabitants, and especially of young generations, from the natural values and realities. It is thus more important than ever to ensure an adequate percentage of green areas for our cities, uniformly distributed within the urban tissue. Green belts, urban forests, parks, green squares or even urban gardens - all these entities play their parts within the urban green network, having certain radiuses of influence and attraction and thus occupying a specific position within the urban hierarchy. In Romania, the terrains left un-built between the collective housing buildings - or apartment blocks, erected during the communist administration and currently constituting public property, have a huge potential regarding the matter of urban greenery, being easily transformed into active and qualitative green areas. However, the local authorities lack the resources (both financial and in terms of human resources) to efficiently develop and then administrate these areas, which are consequently either abandoned, or used as illegal

    Full Text Available Ekološki problemi izazvani saobraćajem pripadaju "prvoj vrsti" zagađenja u urbanim sredinama. Emisije aerozagađenja štetnim materijama, poreklom iz motora SUS, visoke su, bez obzira na mogućnost smanjivanja. Prognoze o rezervama nafte uvek su nametale potrebu i intenzivirale istraživanja supstitucije mineralnih goriva. U svetu je sve aktuelniji trend istraživanja obnovljivih izvora energije. Zaštita životne sredine i smanjenje potrošnje energije glavni su pravci budućeg razvoja motora i vozila. Sa tog aspekta analizirane su emisije prirodnog gasa i biodizela RME u poređenju sa klasičnim gorivom. / Ecology problems of transport appertain "first class" pollution in urban environment. The forecast about the reserves of crude petroleum have always imposed the need for intensified researches on substitution of conventional mineral fuels. The trend of research of renewable sources is more and more actual in the world. Environmental preservation and the reduction of energy consumption are the main directions for future engine and vehicle developments. From that aspect, emissions produced by certain fuels have been analyzed and compared with natural gas and biodiesel RME.

    Full Text Available The built environment contributes around half of total greenhouse gas emissions and with 87% of residential buildings that we will have by 2050 already built, it is vital to adopt sustainable retrofitting practices. The question is: what are the viable solutions? One answer may be green roof retrofitting. The environmental benefits include reduced operational carbon emissions, reduced urban heat island effect, increased bio-diversity, housing temperature attenuation and reduced stormwater run-off. The economic benefits are the reduced maintenance costs and lower running costs. The social gain is the creation of spaces where people have access to green areas. However, the barriers to retrofitting include the perceptions of structural adequacy, the risk of water damage, high installation and maintenance costs, as well as access and security issues. Many Australian and Brazilian residential buildings have metal sheet roofs, a lightweight material with poor thermal performance. During the summer, temperatures in Sydney and Rio de Janeiro reach 45 degrees Celsius, and in both cities, rainfall patterns are changing, with more intense downpours. Furthermore, many residential buildings are leased, and currently, tenants are restricted by the modifications that they can perform to reduce running costs and carbon emissions. This research reports on an experiment on two small-scale metal roofs in Sydney and Rio de Janeiro to assess the thermal performance of portable small-scale modules. The findings are that considerable variation in temperature was found in both countries, indicating that green roof retrofitting could lower the cooling energy demand considerably.

    To compare workforce characteristics and staff perceptions of safety, satisfaction, and stress between Green House (GH) and comparison nursing homes (CNHs). Primary data on staff perceptions of safety, stress, and satisfaction from 13 GHs and 8 comparison NHs in 11 states; secondary data from human resources records on workforce characteristics, turnover, and staffing from 01/01/2011-06/30/2012. Observational study. Workforce data were from human resources offices; staff perceptions were from surveys. Few significant differences were found between GH and CNHs. Exceptions were GH direct caregivers were older, provided twice the normalized hours per week budgeted per resident than CNAs in CNHs or Legacy NHs, and trended toward lower turnover. GH environment may promote staff longevity and does not negatively affect worker's stress, safety perceptions, or satisfaction.

    2005-01-01

    It is shown that the hydrodynamic modes of a dilute granular gas of inelastic hard spheres can be identified, and calculated in the long wavelength limit. Assuming they dominate at long times, formal expressions for the Navier-Stokes transport coefficients are derived. They can be expressed in a form that generalizes the Green-Kubo relations for molecular systems, and it is shown that they can also be evaluated by means of N-particle simulation methods. The form of the hydrodynamic modes to zeroth order in the gradients is used to detect the presence of inherent velocity correlations in the homogeneous cooling state, even in the low density limit. They manifest themselves in the fluctuations of the total energy of the system. The theoretical predictions are shown to be in agreement with molecular dynamics simulations. Relevant related questions deserving further attention are pointed out

  19. Blood gases, biochemistry, and hematology of Galapagos green turtles (Chelonia mydas.

    Full Text Available The green turtle, Chelonia mydas, is an endangered marine chelonian with a circum-global distribution. Reference blood parameter intervals have been published for some chelonian species, but baseline hematology, biochemical, and blood gas values are lacking from the Galapagos sea turtles. Analyses were done on blood samples drawn from 28 green turtles captured in two foraging locations on San Cristóbal Island (14 from each site. Of these turtles, 20 were immature and of unknown sex; the other eight were males (five mature, three immature. A portable blood analyzer (iSTAT was used to obtain near immediate field results for pH, lactate, pO2, pCO2, HCO3-, Hct, Hb, Na, K, iCa, and Glu. Parameter values affected by temperature were corrected in two ways: (1 with standard formulas; and (2 with auto-corrections made by the iSTAT. The two methods yielded clinically equivalent results. Standard laboratory hematology techniques were employed for the red and white blood cell counts and the hematocrit determination, which was also compared to the hematocrit values generated by the iSTAT. Of all blood analytes, only lactate concentrations were positively correlated with body size. All other values showed no significant difference between the two sample locations nor were they correlated with body size or internal temperature. For hematocrit count, the iSTAT blood analyzer yielded results indistinguishable from those obtained with high-speed centrifugation. The values reported in this study provide baseline data that may be useful in comparisons among populations and in detecting changes in health status among Galapagos sea turtles. The findings might also be helpful in future efforts to demonstrate associations between specific biochemical parameters and disease.

    The energy minimization and spin modifications of sorbates with sorbents in magnetic induction method (MIM) play a vital role in yield of fertilizer. Hence, in this article the focus of study is the interaction of sorbates/reactants (H2, N2 and CO2) in term of average total adsorption energies, average isosteric heats of adsorption energies, magnetic moments, band gaps energies and spin modifications over identical cone tips nanocatalyst (sorbents) of Fe2O3, Fe3O4 (magnetic), CuO and Al2O3 (non-magnetic) for green nano-fertilizer synthesis. Study of adsorption energy, band structures and density of states of reactants with sorbents are purely classical and quantum mechanical based concepts that are vividly illustrated and supported by ADSORPTION LOCATOR and Cambridge Seriel Total Energy Package (CASTEP) modules following classical and first principle DFT simulation study respectively. Maximum values of total average energies, total average adsorption energies and average adsorption energies of H2, N2 and CO2 molecules are reported as -14.688 kcal/mol, -13.444 kcal/mol, -3.130 kcal/mol, - kcal/mol and -6.348 kcal/mol over Al2O3 cone tips respectively and minimum over magnetic cone tips. Whereas, the maximum and average minimum values of average isosteric heats of adsorption energies of H2, N2 and CO2 molecules are figured out to be 3.081 kcal/mol, 4.842 kcal/mol and 6.848 kcal/mol, 0.988 kcal/mol, 1.554 kcal/mol and 2.236 kcal/mol over aluminum oxide and Fe3O4 cone tips respectively. In addition to the adsorption of reactants over identical cone sorbents the maximum and minimum values of net spin, electrons and number of bands for magnetite and aluminum oxide cone structures are attributed to 82 and zero, 260 and 196, 206 and 118 for Fe3O4 and Al2O3 cones respectively. Maximum and least observed values of band gap energies are figured out to be 0.188 eV and 0.018 eV with Al2O3 and Fe3O4 cone structures respectively. Ultimately, with the adsorption of reactants an

    To describe the Green House (GH) model of nursing home (NH) care, and examine how GH homes vary from the model, one another, and their founding (or legacy) NH. Data include primary quantitative and qualitative data and secondary quantitative data, derived from 12 GH/legacy NH organizations February 2012-September 2014. This mixed methods, cross-sectional study used structured interviews to obtain information about presence of, and variation in, GH-relevant structures and processes of care. Qualitative questions explored reasons for variation in model implementation. Interview data were analyzed using related-sample tests, and qualitative data were iteratively analyzed using a directed content approach. GH homes showed substantial variation in practices to support resident choice and decision making; neither GH nor legacy homes provided complete choice, and all GH homes excluded residents from some key decisions. GH homes were most consistent with the model and one another in elements to create a real home, such as private rooms and baths and open kitchens, and in staff-related elements, such as self-managed work teams and consistent, universal workers. Although variation in model implementation complicates evaluation, if expansion is to continue, it is essential to examine GH elements and their outcomes. © Health Research and Educational Trust.

    NOx, a significant portion of fossil fuel flue gases, are among the most serious environmental issues in the world and must be removed in an additional costly gas treatment step. This study evaluated the growth of the green alga Chlorella sp. C2 under a nitrite-simulated NOx environment and the removal rates of actual flue gas fixed salts (FGFSs) from Sinopec's Shijiazhuang refinery along with lipid production. The results showed that nitrite levels lower than 176.5 mM had no significant adverse effects on the cell growth and photosynthesis of Chlorella sp. C2, demonstrating that this green alga could utilize nitrite and NOx as a nitrogen source. High concentrations of nitrite (88.25-176.5 mM) also resulted in the accumulation of neutral lipids. A 60% nitrite removal efficiency was obtained together with the production of 33% algae lipids when cultured with FGFS. Notably, the presence of nitrate in the FGFS medium significantly enhanced the nitrite removal capability, biomass and lipid production. Thus, this study may provide a new insight into the economically viable application of microalgae in the synergistic combination of biological DeNOx of industrial flue gases and biodiesel production.

    Cellular mobile service is a rapidly expanding and a very competitive business worldwide, including developing countries. This paper proposes that the suitable alternative solution of grid power is the stand-alone PV/wind hybrid energy system with diesel generator as a backup for cellular mobile telephony base station site in isolated areas. It is expected that the newly developed and installed system would provide very good opportunities for mobile telephony base station in near future. In addition, protecting the environment and combating climate change are two of the most pressing challenges facing humankind. As energy prices soar, network operators are increasingly scrutinizing their environmental and social responsibilities. This system will be more cost effective and environmental friendly over the conventional diesel generator. Approximately 70-80% fuel cost over conventional diesel generator and the emission of CO 2 and other harmful gasses in environments were reduced. (author)

    The recent crisis in electricity supply raised in all Brazilians the necessity in improving energy resources. The expansion of generation capacity cannot be seen as the unique solution: optimise what is available already is at least so important than to expand. The rational use of energy resources brings additional benefits as reduced environmental impacts, replacement of equipment and following incentives to industry and employment. Promote coordinated actions has been challenging in several places. In Brazil, GERBI Program aims to address several market barriers, developing activities in different fronts: service suppliers' qualification, preparation of financial agents and, mainly, engage industrial end users for improved solutions. The paper presents GERBI Program structure as an incentive to rational energy use in industrial facilities, focused on GHG emissions reduction. The Program is structured in three main components: energy efficiency projects development, supporting industries to implement better practices and efficient technologies, development of CDM candidate projects, making use of 'carbon credits' resulted from reduced emissions, and training and qualification.

    The implementation of Green Building criteria is relatively new in architectural practice, especially in Indonesia. Consequently, the integration of these criteria into design process has the potential to change the design process itself. The implementation of the green building criteria into the conventional design process will be discussed in this paper. The concept of this project is to design a residential unit with a natural air-conditioning system. To achieve this purpose, the Green Building criteria has been implemented since the beginning of the design process until the detailing process on the end of the project. Several studies was performed throughout the design process, such as: (1) Conceptual review, where several professionally proved theories related to Tropical Architecture and passive design are used for a reference, and (2) Computer simulations, such as Computational Fluid Dynamics (CFD) and wind tunnel simulation, used to represent the dynamic response of the surrounding environment towards the building. Hopefully this paper may become a reference for designing a green residential building.

    Climate change is the most important crisis of our lifetime. For policy makers to take action to combat the effects of climate change, they will need definitive proof that it is occurring globally. We have developed a low-cost ground instrument - a portable miniaturized laser heterodyne radiometer (mini-LHR) - capable of measuring concentrations of two of the most potent anthropogenic greenhouse gases, CO2 and methane, in columns in the atmosphere. They work by combining sunlight that has undergone absorption by gases with light from a laser. This combined light is detected by a photoreciever and a radio frequency beat signal is produced. From this beat signal, concentrations of these gases throughout the atmospheric column can be determined. A network of mini-LHR instruments in locations around the world will give us the data necessary to significantly reduce uncertainty in greenhouse gas sinks and sources contributing to climate change. Each instrument takes one reading per minute while the sun is up. With a goal to establish up to 500 instrument sites, the estimated total data per day will likely exceed 1GB. Every piece of data must be sorted as it comes in to determine whether it is a good or bad reading. The goal of the citizen science project is to collaborate with citizen scientists enrolled with Zooniverse.org to cycle through our data and help sort it, while also learning about the mini-LHR, greenhouse gases and climate change. This data will be used to construct an algorithm to automatically sort data that relies on statistical analyses of the previously sorted data.

    Full Text Available The main objective of the study was to assess particulate matter (PM exposure levels for both the farmer and the veterinarian during different operational tasks in pig-fattening houses, and to estimate their exposure levels on a daily working basis (time-weighted average (TWA. The measured PM fractions were: inhalable and respirable PM, PM10, PM2.5 and PM1. The effects of pig age, pen floor type (conventional or low emission surface and cleaning of the pens on the personal PM exposure were also investigated. Indoor concentrations of NH[sub]3[/sub], CH[sub]4[/sub], and CO[sub]2[/sub] were additionally measured during some operational tasks. The results showed that personal exposure levels can become extremely high during some operational tasks performed by the farmer or veterinarian. The highest concentration levels were observed during feed shovelling and blood sampling, the lowest during the weighing of the pigs. For the farmer, the estimated TWA exposure levels of inhalable and respirable PM were 6.0 and 0.29 mg m[sup] -3[/sup] , respectively. These exposure levels for the veterinarian were, respectively, 10.6 and 0.74 mg m[sup] -3[/sup] . The PM concentration levels were mainly determined by the performed operational tasks. There was no significant effect of pig age, pen floor type, nor cleaning of the pens on the personal exposure levels.

    The aim of project is to estimate the contribution of lithospheric flue gas emission of gases CH4, CO2, H2 in the general composition of atmospheric pollution of Arctic zone. The main task is organization of the ecological monitoring in the area of exploitation of large apatite and rare earth ore deposit from Khibine massive on the base of modern WSN (wireless sensor network) technologies. Application network consist from sensors of gas H2, CH4, CO2, complex autonomous equipment for measurement temperature, pressure, humidity and network of telecommunications (used ZigBee protocol). Our project offer technical decisions for experimentally-methodical monitoring network on the base of WSN and the high-sensitive sensors of hydrogen and methane, software and electronic equipment with a transmitter network. This work is the first project in Russia. The advantages of this technology is autonomous work (to several months and more), high-frequency programmable measurement of gas sensor, low cost (on one node of network), possibility to connect to one node of supervision a several types of sensors. And as a result is complex monitoring of environment. It has long been known that the pollution in Arctic Khibine and Lovosero region contains unusually high levels of hydrocarbon gases (HCG) [Petersilie,1964]. The presence of these gases has a number of practical implications and it is therefore important to understand their source and distribution. Among alkaline intrusive complexes with high (for magmatic rocks) concentrations of hydrocarbon and hydrogen- hydrocarbon gases occluded as fluid inclusions in minerals. The Khibina and Lovozero massives are well known, as region of spontaneous emissions of these gases from lithosphere [Khitarov et al., 1979; Ikorskii et al., 1992; Beeskow 2007; Nivin 2005, 2009]. The presence of the HCG, however, raises a number of questions and possibilities. It is unclear how homogeneously the HCG are distributed through the complex? What is the

    Full Text Available Recently, much attention has been given to Stochastic demand due to uncertainty in the real -world. In the literature, decision-making models and suppliers' selection do not often consider inventory management as part of shopping problems. On the other hand, the environmental sustainability of a supply chain depends on the shopping strategy of the supply chain members. The supplier selection plays an important role in the green chain. In this paper, a multi-objective nonlinear integer programming model for selecting a set of supplier considering Stochastic demand is proposed. while the cost of purchasing include the total cost, holding and stock out costs, rejected units, units have been delivered sooner, and total green house gas emissions are minimized, while the obtained total score from the supplier assessment process is maximized. It is assumed, the purchaser provides the different products from the number predetermined supplier to a with Stochastic demand and the uniform probability distribution function. The product price depends on the order quantity for each product line is intended. Multi-objective models using known methods, such as Lp-metric has become an objective function and then uses genetic algorithms and simulated annealing meta-heuristic is solved.

    Full Text Available Agricultural sector experiences the application of automated systems since two decades ago. These systems are applied to harvest fruits in agriculture. Computer vision is one of the technologies that are most widely used in food industries and agriculture. In this paper, an automated system based on computer vision for harvesting greenhouse tomatoes is presented. A CCD camera takes images from workspace and tomatoes with over 50 percent ripeness are detected through an image processing algorithm. In this research three color spaces including RGB, HSI and YCbCr and three algorithms including threshold recognition, curvature of the image and red/green ratio were used in order to identify the ripe tomatoes from background under natural illumination. The average error of threshold recognition, red/green ratio and curvature of the image algorithms were 11.82%, 10.03% and 7.95% in HSI, RGB and YCbCr color spaces, respectively. Therefore, the YCbCr color space and curvature of the image algorithm were identified as the most suitable for recognizing fruits under natural illumination condition.

    In response to demand for the expansion of living space, the living environment of semi-underground room has been investigated. An attached green house (passive solar house) is adjacent to the semi-underground room. This is reinforced concrete construction, having flat type solar collector on its roof and lighting window in its north side. It does not have artificial air conditioners. Based on the measurements of daylight factor, artificial lighting is not required at the window in the daytime, but it is desirable to use daylight and artificial lighting together at the center. The performance of sound insulation depends on the high performance soundproof sash level. There is less daily temperature variation due to its large heat capacity, and less yearly temperature variation than the outside. By shielding the solar radiation, the insolation in the green house in summer can be restricted in the same as in winter. The insolation can be easily received in winter due to its large vertical intensity of solar radiation. The green house in the south side is useful for improving the living environment of semi-underground room. The temperature rise in the semi-underground room can be restricted by opening window in summer. It is desirable for the comfortable living to use artificial cooling to reduce the daytime temperature by 3 to 4{degree}C. In winter, it is comfortable to heat by 4 to 5{degree}C. 2 refs., 7 figs.

    In 2006, California passed the landmark assembly bill AB-32 to reduce California's emissions of greenhouse gases (GHGs) that contribute to global climate change. AB-32 commits California to reduce total GHG emissions to 1990 levels by 2020, a reduction of 25 percent from current levels. To verify that GHG emission reductions are actually taking place, it will be necessary to measure emissions. We describe atmospheric inverse model estimates of GHG emissions obtained from the California Greenhouse Gas Emissions Measurement (CALGEM) project. In collaboration with NOAA, we are measuring the dominant long-lived GHGs at two tall-towers in central California. Here, we present estimates of CH{sub 4} emissions obtained by statistical comparison of measured and predicted atmospheric mixing ratios. The predicted mixing ratios are calculated using spatially resolved a priori CH{sub 4} emissions and surface footprints, that provide a proportional relationship between the surface emissions and the mixing ratio signal at tower locations. The footprints are computed using the Weather Research and Forecast (WRF) coupled to the Stochastic Time-Inverted Lagrangian Transport (STILT) model. Integral to the inverse estimates, we perform a quantitative analysis of errors in atmospheric transport and other factors to provide quantitative uncertainties in estimated emissions. Regressions of modeled and measured mixing ratios suggest that total CH{sub 4} emissions are within 25% of the inventory estimates. A Bayesian source sector analysis obtains posterior scaling factors for CH{sub 4} emissions, indicating that emissions from several of the sources (e.g., landfills, natural gas use, petroleum production, crops, and wetlands) are roughly consistent with inventory estimates, but livestock emissions are significantly higher than the inventory. A Bayesian 'region' analysis is used to identify spatial variations in CH{sub 4} emissions from 13 sub-regions within California

    Green house gas emission reduction is mostly directed to CO 2 , a byproduct of combustion of fossil fuels. While Australia is in a disadvantageous position relative to many countries because of heavy reliance on coal, compared to say natural gas, wind nuclear or hydro source, Australian technology is helping the worlds fossil fuel fired power stations and many industrial boilers minimise total CO 2 emissions by increasing efficiency of combustion, by excess air administration. CSIRO developed the world's leading Zirconia sensor technology for flue gas oxygen measurement. An Australian company commercialised this technology and now dominates the Australian power station market with the technology because it is for the first time reliable enough for closed-loop automatic air trimming control especially on gas fired plant. This paper will explain the relationships between fossil fuel stoichiometry, excess air and CO 2 emissions and zirconia sensor flue gas oxygen measurement and control. By carefully controlling excess air reductions in CO 2 emissions of 3-5% are readily achievable along with reductions in fuel costs of the same order. Side benefits can include reduction in NOx and increased safety of the operation. This is expected to be a low cost and increasingly popular measure for industrial enterprises to attack the greenhouse problem with an easy win-win result, as compared to many other greenhouse emission reduction strategies available

    system. These increases were great than anticipated based on theoretical methane production from the additional chemical oxygen demand (COD) of the co-digestates. Co-digestion of the most promising wastes with primary sludge was estimated to generate enough electricity to power more than 2500 houses. Synergistic outcomes of co-digestion may be caused by chances in microbial community resulting in more rapid methane production rate and higher specific methanogenic activities of the biomass against acetate, propionate and H2 as substrates. The presence of Methanospirillum hungatei correlated to higher SMAs in the Co-Digester 1 system. In subsequent full-scale testing, acid whey in addition to primary sludge increased methane production by 16 %, biogas methane content by 5%, methane yield per VS destroyed by 9% ( from 650 to 710 L CH4 / kg VSdestroyed ) and volatile solids removal by 20%. Co-digestion is a promising technology to increase renewable energy production and convert municipal digesters into regional renewable energy facilities.

    The Observations and Modeling of the Green Ocean Amazon (GoAmazon2014/5) experiment took place around the urban region of Manaus in central Amazonia across two years. The urban pollution plume was used to study the susceptibility of gases, aerosols, clouds, and rainfall to human activities in a tropical environment. Many aspects of air quality, weather, terrestrial ecosystems, and climate work differently in the tropics than in the more thoroughly studied USA, employed an unparalleled suite of measurements at nine ground sites and onboard two aircraft to investigate the flow of background air into Manaus, the emissions into the air over the city, and the advection of the pollution downwind of the city. Herein, to visualize this train of processes and its effects, observations aboard a low-flying aircraft are presented. Comparative measurements within and adjacent to the plume followed the emissions of biogenic volatile organic carbon compounds (BVOCs) from the tropical forest, their transformations by the atmospheric oxidant cycle, alterations of this cycle by the influence of the pollutants, transformations of the chemical products into aerosol particles, the relationship of these particles to cloud condensation nuclei (CCN) activity, and the differences in cloud properties and rainfall for background compared to polluted conditions. The observations of the GoAmazon2014/5 experiment illustrate how the hydrologic cycle, radiation balance, and carbon recycling may be affected by present-day as well as future economic development and pollution over the Amazonian tropical forest.

    Wheat (Triticum aestivum L.) is one of the most important agricultural crops in both space such as Bioregenerative Life Support Systems (BLSS) and urban agriculture fields, and its cultivation is affected by several environmental factors. The objective of this study was to investigate the influences of different environmental conditions (BLSS, plant factory, green house and field) on the wheat growth, thousand kernel weight (TKW), harvest index (HI), biomass yield and quality during their life cycle. The results showed that plant height partially influenced by the interaction effects with environment, and this influence decreased gradually with the plant development. It was found that there was no significant difference between the BLSS and plant factory treatments on yields per square, but the yield of green house and field treatments were both lower. TKW and HI in BLSS and plant factory were larger than those in the green house and field. However, grain protein concentration can be inversely correlated with grain yield. Grain protein concentrations decreased under elevate CO2 condition and the magnitude of the reductions depended on the prevailing environmental condition. Conditional interaction effects with environment also influenced the components of straw during the mature stage. It indicated that CO2 enriched environment to some extent was better for inedible biomass degradation and had a significant effect on "source-sink flow" at grain filling stage, which was more beneficial to recycle substances in the processes of the environment regeneration.

    Background Growing attention in the past few decades has focused on improving care quality and quality of life for nursing home residents. Many traditional nursing homes have attempted to transform themselves to become more homelike emphasizing individualized care. This trend is referred to as nursing home culture change in the U.S. A promising culture change nursing home model, the Green House (GH) nursing home model, has shown positive psychological outcomes. However, little is known about whether the GH nursing home model has positive effects on physical function compared to traditional nursing homes. Objectives To examine the longitudinal effects of the GH nursing home model by comparing change patterns of ADL function over time between GH home residents and traditional nursing home residents. Design A retrospective longitudinal study. Settings Four GH organizations (nine GH units and four traditional units). Participants A total of 242 residents (93 GH residents and 149 traditional home residents) who had stayed in the nursing home at least six months from admission. Methods The outcome was ADL function, and the main independent variable was the facility type in which the resident stayed: a GH or traditional unit. Age, gender, comorbidity score, cognitive function, and depressive symptoms at baseline were controlled. All of these measures were from a minimum dataset. Growth curve modeling and growth mixture modeling were employed in this study for longitudinal analyses. Results The mean ADL function showed deterioration over time, and the rates of deterioration between GH and traditional home residents were not different over time. Four different ADL function trajectories were identified for 18 months, but there was no statistical difference in the likelihood of being in one of the four trajectory classes between the two groups. Conclusions Although GH nursing homes are considered to represent an innovative model changing the nursing home environment into more

    This Final Technical Report describes the work and accomplishments of the project entitled, “Green-House-Gas-Reduced Coal-and-Biomass-to-Liquid-Based Jet Fuel (GHGR-CBTL) Process”. The main objective of the project was to raise the Technology Readiness Level (TRL) of the GHGR-CBTL fuel-production technology from TRL 4 to TRL 5 by producing a drop-in synthetic Jet Propellant 8 (JP-8) with a greenhouse-gas footprint less than or equal to petroleum-based JP-8 by utilizing mixtures of coal and biomass as the feedstock. The system utilizes the patented Altex fuel-production technology, which incorporates advanced catalysts developed by Pennsylvania State University. While the system was not fabricated and tested, major efforts were expended to design the 1-TPD and a full-scale plant. The system was designed, a Block-Flow Diagram (BFD), a Process-Flow Diagram (PFD), and Piping-and-Instrumentation Diagrams (P&IDs) were produced, a Bill of Materials (BOM) and associated spec sheets were produced, commercially available components were selected and procured, custom components were designed and fabricated, catalysts were developed and screened for performance, and permitting activities were conducted. Optimization tests for JP-8 production using C2 olefin as the feed were performed over a range of temperatures, pressures and WHSVs. Liquid yields of between 63 to 65% with 65% JP-8 fraction (41-42% JP-8 yield) at 50 psig were achieved. Life-Cycle Analysis (LCA) was performed by Argonne National Laboratory (ANL), and a GHGR-CBTL module was added to the Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET®) model. Based upon the experimental results, the plant design was reconfigured for zero natural-gas imports and minimal electricity imports. The LCA analysis of the reconfigured process utilizing the GREET model showed that if the char from the process was utilized to produce combined heat and power (CHP) then a feed containing 23 wt% biomass and

    The alternation of oxidizing and reducing conditions in paddy soils results in considerable complexity in the biogeochemical cycling of elements and their interactions, influencing important soil processes. Water management practices may play an important role in controlling the loss of nutrients from rice paddies to surface and subsurface waters, as well as soil organic matter (SOM) stabilization and the emission of green-house gases (GHG) such as methane and nitrous oxide. The aim of this study was therefore to evaluate the interaction between changes in soil redox conditions and element cycling in temperate paddy soils as a function of different water management practices. The research was carried out within an experimental platform (1.2 ha) located at the Rice Research Center of Ente Nazionale Risi (Castello d'Agogna, PV, NW Italy) where three water management practices are being compared with two plots for each treatment. These included (i) rice cultivation under traditional submerged conditions (FLD); (ii) seeding under dry soil conditions and flooding delayed by about 40 days (DRY); (iii) seeding under dry soil conditions and rotational irrigation (IRR). Surface and subsurface (25, 50 and 75 cm) water samples were collected at regular intervals over the cropping season from V-notch weirs and porous ceramic suction cups installed in each plot, and subsequently analyzed for DOC, SUVA, Fe(II), ammonium and nitrate-N. Moreover, methane and nitrous oxide fluxes were measured in situ by the closed-chamber technique. DOC concentrations in soil solutions were generally higher in FLD and DRY treatments with respect to IRR throughout the cropping season. Higher DOC contents after field flooding in FLD and DRY treatments also corresponded with greater concentrations of reduced Fe, higher SUVA values, lower Eh values and higher pH values, suggesting that desorption of more aromatic, mineral-associated SOM could be responsible for the observed increase in DOC. These

    Full Text Available The first step to reduce greenhouse gas emissions from buildings is to be able to count them. If this counting is integrated in the design process the impact of architectural design strategies can be evaluated more easily and a building with reduced emissions can be developed. Fifty greenhouse gas calculators and energy modeling software were compared in the main areas in which buildings are responsible for carbon emissions: operation, water, construction, waste and transportation to and from the building. These tools had to be free and easy to use so that they could be used by everybody in the initial phases of the architectural design process, while providing sufficient precision to provide useful input to the designer. The effect of modifying the envelope insulation, the quality of the windows, the efficiency of the heating and cooling systems, and integrating direct gain and night ventilation, on operation emissions was evaluated with two energy modeling tools: HEED and Design Builder. Results demonstrated that implementing appropriate design strategies significantly reduced emissions from operation in all climates. An easy to implement protocol that combines several tools for GHG counting in buildings is provided at the end.

    Full Text Available Daqing is situated in one of the severely cold regions of China. The living environment in this region is extremely poor because of the harsh climate and the backward economy. The external wall is an important component of the external envelope of buildings, and it greatly contributes to the indoor thermal environment. By taking the external wall as the research object, this study summarizes the characteristics of the external wall structure and analyzes the common materials used in existing rural residences. Specifically, we combine life cycle theory and ecological footprint (EF theory and introduce the green external wall structure, as well as its application in practice, in accordance with the local ecosystem. Results show that anecological residence offers a better environment and greater economic benefits than a traditional residence. The annual energy consumption, CO2 consumption, and EF of the ecological residence in this study are lower than those of the traditional residence by 69.61%, 17.5 t, and 99.47%, respectively.

    Industrial gas companies have fought hard to boost sales and hold margins in the tough economic climate, and investments are well down from their 1989-'91 peak. But 'our industry is still very strong long term' says Alain Joly, CEO of industry leader L'Air Liquide (AL). By 1994, if a European and Japanese recovery follows through on one in the U.S., 'we could see major [investment] commitments starting again,' he says. 'Noncryogenic production technology is lowering the cost of gas-making possible new applications, oxygen is getting plenty of attention in the environmental area, and hydrogen also fits into the environmental thrust,' says Bob Lovett, executive v.p./gases and equipment with Air Products ampersand Chemicals (AP). Through the 1990's, 'Industrial gases could grow even faster than in the past decade,' he says. Virtually a new generation of new gases applications should become reality by the mid-1990s, says John Campbell, of industry consultants J.R. Campbell ampersand Associates (Lexington, MA). Big new oxygen volumes will be required for powder coal injection in blast furnaces-boosting a steel mill's requirement as much as 40% and coal gasification/combined cycle (CGCC). Increased oil refinery hydroprocessing needs promise hydrogen requirements

  6. Noble Gases

    Science.gov (United States)

    Podosek, F. A.

    2003-12-01

    The noble gases are the group of elements - helium, neon, argon, krypton, xenon - in the rightmost column of the periodic table of the elements, those which have "filled" outermost shells of electrons (two for helium, eight for the others). This configuration of electrons results in a neutral atom that has relatively low electron affinity and relatively high ionization energy. In consequence, in most natural circumstances these elements do not form chemical compounds, whence they are called "noble." Similarly, much more so than other elements in most circumstances, they partition strongly into a gas phase (as monatomic gas), so that they are called the "noble gases" (also, "inert gases"). (It should be noted, of course, that there is a sixth noble gas, radon, but all isotopes of radon are radioactive, with maximum half-life a few days, so that radon occurs in nature only because of recent production in the U-Th decay chains. The factors that govern the distribution of radon isotopes are thus quite different from those for the five gases cited. There are interesting stories about radon, but they are very different from those about the first five noble gases, and are thus outside the scope of this chapter.)In the nuclear fires in which the elements are forged, the creation and destruction of a given nuclear species depends on its nuclear properties, not on whether it will have a filled outermost shell when things cool off and nuclei begin to gather electrons. The numerology of nuclear physics is different from that of chemistry, so that in the cosmos at large there is nothing systematically special about the abundances of the noble gases as compared to other elements. We live in a very nonrepresentative part of the cosmos, however. As is discussed elsewhere in this volume, the outstanding generalization about the geo-/cosmochemistry of the terrestrial planets is that at some point thermodynamic conditions dictated phase separation of solids from gases, and that the

    The LIGHTEnUP Analysis Tool (Lifecycle Industry GreenHouse gas, Technology and Energy through the Use Phase) has been developed for The United States Department of Energy’s (U.S. DOE) Advanced Manufacturing Office (AMO) to forecast both the manufacturing sector and product life-cycle energy consumption implications of manufactured products across the U.S. economy. The tool architecture incorporates publicly available historic and projection datasets of U.S. economy-wide energy use including manufacturing, buildings operations, electricity generation and transportation. The tool requires minimal inputs to define alternate scenarios to business-as-usual projection data. The tool is not an optimization or equilibrium model and therefore does not select technologies or deployment scenarios endogenously. Instead, inputs are developed exogenous to the tool by the user to reflect detailed engineering calculations, future targets and goals, or creative insights. The tool projects the scenario’s energy, CO2 emissions, and energy expenditure (i.e., economic spending to purchase energy) implications and provides documentation to communicate results. The tool provides a transparent and uniform system of comparing manufacturing and use-phase impacts of technologies. The tool allows the user to create multiple scenarios that can reflect a range of possible future outcomes. However, reasonable scenarios require careful attention to assumptions and details about the future. This tool is part of an emerging set of AMO’s life cycle analysis (LCA) tool such as the Material Flows the Industry (MFI) tool, and the Additive Manufacturing LCA tool.

    It is fairly well recognised that greenhouse gases (GHG) have an impact on the global climate as they trap heat in the atmosphere. With the result earth is warmed in manner similar to the glass panels of a greenhouse increase. Hence the name 'green house effect' during the last two centuries in CO/sub 2/ in the atmosphere has been reckoned at 25%, with corresponding values for CH/sub 4/ and N/sub 2/O as 100% and 10% during 1950-80. CFC concentration increased by 10%. It is estimated that the earth has warmed by 0.5 deg. C and sea level has increased by 15 cm over the last 100 years or so. The major cause has been attributed to the process of industrialization. (author)

    Wegener, Jens-Karl

    2006-12-15

    This monograph is concerned with different aspects of green house gas (GHG) emissions in agriculture. The first part summarizes the total amount of GHG emissions and analyses them regarding their composition. A differentiation is made between the emissions which are already linked to agriculture (source group agriculture: ''digestion'', ''manure-management'' and ''agricultural soils'') within the ''National Report on GHG Emissions'' and those which can be counted primarily in addition to agriculture (''energy'' and ''land use and land use change''). Depending on which database is used, agriculture is participating in emitting green house gases with 6.3% or 11.1% of total German GHG emissions in 2004. This means that agriculture is an important polluter. The development of GHG emissions in agriculture compared to the year 1990 is -18.5% for the source group agriculture. This means that the source group has reduced more emissions than the average (-17.5%) over all domains published within the National Report. Regarding the sources ''energy'' and ''land use and land use change'' in addition emission reduction is -16.4% in the same period and thus worse than the average. Moreover, realized emission reductions are predominantly based on structural changes, less on systematical measures. This fact raises the question how agriculture can make a contribution to the reduction of GHG emissions in future particularly with regard to higher aims in climate politics. For this reason the second part of the monograph identifies capacities for the reduction of GHG emissions by using available agricultural biomass for energetic purposes. Due to the heterogeneity of biomass and the variety of its possible products, a lot of technical processes concerning the conversion of biomass into energy exist in practice. Since all of

    Self-sufficiency type houses are outlined. On condition that people gain a certain amount of income in relation with the society, they self-suffice under the given environment, allowing themselves to accept a minimum of industrial products with small environmental load. Ordinary supply from outside of fossil energy and materials which depend on it is minimized. Types are classified into three: energy, energy materials and perfect self-sufficiency. A study project for environment symbiotic houses is progressing which is planned by the Ministry of Construction and Institute of Building Energy Conservation and is invested by a private company. Its target is making a house for halving an environmental load by CO{sub 2}, for the purpose of creating the environment symbiotic house which is nice to and in harmony with the global environment and human beings. As a part of the studies on energy-saving and resource conservation on houses, introduced is a plan of an autonomous house at Izu-Atagawa. The passive method and high thermal-insulation are used for air conditioning, and hot spring water for hot water supply. Electric power is generated by hydroelectric power generation using mountain streams and by solar cells. Staple food is purchased, while subsidiary food is sufficed. 17 refs., 4 figs., 1 tab.

    The horizontal land was made by burying the valley made by abandoned mine with waste rocks in Okawa Village in Kochi prefecture, and hydroponic cultivation was carried out. Possibility of use of air flow heat energy using the mine ventilation in order to economize and save energy of this cultivation was studied. If continuous green house ventilation is carried using air drawn from tunnel, applicable house temperature and humidity for certain scale of green house was possible to control within constant limit. When warming of 4 green houses from November to April was carried out, the maximum power load, the heating load for January, was 1,746.43kW and ventilation rate was 5.51 times/hour. Consumption for February was higher than January because of decrease of airflow drawn energy inside the tunnel. As for cooling from July to September, for August as the hottest month, maximum consumed energy required to maintain green house temperature was 2,058.28kW, and demand of airflow rate drawn inside the tunnel was 128.38m[sup 3]/s. 7 refs., 7 figs., 5 tabs.

    To evaluate the importance and benefits of using gases in vitreoretinal surgery. The gases represent a wide group of substances used in eye surgery for more than 100 years. The role of intraocular gases in vitreoretinal surgery is irreplaceable. Their use is still considered to be the "gold standard". An important step in eye surgery was the introduction of expanding gases--sulfur hexafluoride and perfluorocarbons into routine clinical practice. The most common indications for the use of intraocular gases are: retinal detachment, idiopathic macular hole, complications of vitreoretinal surgery and others. The introduction of intraocular gases into routine clinical practice, along with other modern surgical techniques resulted in significant improvement of postoperative outcomes in a wide range of eye diseases. Understanding the principles of intraocular gases use brings the benefits to the patient and physician as well. Due to their physical and chemical properties they pose far the best and most appropriate variant of intraocular tamponade. Gases also bring some disadvantages, such as difficulties in detailed fundus examination, visual acuity testing, ultrasonographic examination, difficulties in application of intravitreal drugs or reduced possibility of retina laser treatment. The gases significantly change optical system properties of the eye. The use of gases in vitreoretinal surgery has significantly increased success rate of retinal detachment surgery, complicated posterior segment cases, trauma, surgery of the macula and other diseases.

    Nitric acid production is an important source of nitrous oxide, one of the green-house gases. Catalytic decomposition of N2O in nitric acid tail-gases might be a possibility for emission reduction, but technology is not yet available. As a part of development of suitable catalytic systems, research was performed, aiming at: gaining an improved understanding of catalytic decomposition of N2O and the inhibiting effects of NO, NO2, H2O and O2; and preparing a 'go-no go' decision whether or not to proceed with subsequent re-search and development and if yes, to indicate what technology further development should aim for. Due to the presence of NOx and water in the nitric acid tail gases, catalytic decomposition proves not to be feasible at temperatures below 350C. At higher temperatures possibilities do exist and a number of promising catalysts are identified. These are active (80 - 100 % conversion) in the temperature range of 400 - 500C and under simulated tail gas conditions. Considering process conditions only (temperatures and composition of the tail-gases), the catalysts studied (pref. the Rh/Al2O3 types) could be in principle applied successfully in all Dutch nitric acid plants

    Full Text Available The term “eco-city,” and similar concepts such as “green” and “sustainable” cities, has evolved overtime concurrent to the development of the understanding of social change and mankind’s impact on environmental and economic health. With the advent of climate change impacts, modern economies developed the green city policy to create sustainable urban development, low emission, and environmentally friendly cities. In South Africa municipalities, including Buffalo City Metropolitan Municipality (BCMM have been tasked to and implement the green city policy. However, BCMM is yet to develop the green city policy that clearly articulate how the municipality will combat climate change and reduce its Green House Gases (GHG emissions in its spatial planning designs. Against this background, this article reviews and analyses green policy landscape in Metropolitan Municipalities. It is envisaged that the research will provide the basis for the development of a comprehensive green policy strategies and programmes for the local transition to action in Buffalo City Metropolitan Municipality, in the Eastern Cape Province.

    The paper aims to present a comprehensive framework for the influences of green perceived risk, green image, green trust and green satisfaction to green loyalty. The paper also seeks to account explicitly for the differences in green perceived risk, green image, green trust, green satisfaction and green loyalty found among green products customers. Data were obtained from 155 green products customers. Structural equation modeling was used in order to test the proposed hypotheses. The findings show that green image, green trust and green satisfaction has positive effects to green loyalty. But green perceived risk has negative effects to green image, green trust and green satisfaction. However, green perceived risk, green image, green trust and green satisfaction also seems to be a good device to gain green products customers from competitors. The contributions of the paper are, firstly, a more complete framework of the influences of green perceived risk, green image, green trust and green satisfaction to green loyalty analyses simultaneously. Secondly, the study allows a direct comparison of the difference in green perceived risk, green image, green trust, green satisfaction and green loyalty between green products customers.

It takes three classes to plan and form the clay, and another two to underglaze and glaze the final products.

    The aims of the study were to investigate the application of banana peels as adsorbent for the removal of CO, NO, NOx and SO2 gases from motorcycles emissions. The effect of differents thermal activation on the characteristics of banana peels adsorbent (BPA) such as moisture content, ash content, volatile matter and fixed carbon has been studied using proximate analysis. The study of Iodine adsorption capacity of BPA was obtained at 952 mg/g adsorbent. Structure and morphology of BPA were characterized by Fourier transform infrared (FTIR) and field emission scanning electron microscopy (SEM). The results showed that BPA could significantly adsorbed the CO and SO2 gases emissions from motorcycles, but not applicable for NO, NOx gases. After 10 minutes of flue gas analysis at idle mode using BPA adsorption tube, CO gas could be totally removed, from initial 19618 ppm to 0 ppm, while SO2 gas could also be totally removed from 24523 ppm to 0 ppm. SEM test showed that temperature of activation had significant effect on the size of pores of BPA formed. BPA was suitable for application in removing CO and SO2 gases emissions from motorcycles and it helps to reduce the green house gas effects of fossil fuel to the environment.

    The members of the Swain family- Dr. Charles "Bill" Swain, wife Elaine, daughter Carol, 17, son "Chuck", 12, and dog Susie have an interesting assignment. They are active participants in an important NASA research program involving the application of space-age technology to home construction. b' Transplanted Floridians, the Swains now reside in NASA's Tech House, loatedat Langley Research Center, Hampton, Virginia. Their job is to use and help evaluate the variety of advanced technology systems in Tech House. A contemporary three-bedroom home, Tech House incorporates NASA technology, the latest commercial building techniques and other innovations, all designed to reduce energy and water consumption and to provide new levels of comfort, convenience, security and fire safety. Tech House equipment performed well in initial tests, but a house is not a home until it has people. That's where the Swains come in. NASA wants to see how the various systems work under actual living conditions, to confirm the effectiveness of the innovations or to determine necessary modifications for improvement. The Swains are occupying the house for a year, during which NASA engineers are computer monitoring the equipment and assembling a record of day-to-day performance. . Tech House is a laboratory rather than a mass production prototype, but its many benefits may influence home design and construction. In a period of sharply rising utility costs, widespread adoption of Tech House features could provide large-scale savings to homeowners and potentially enormous national benefit in resources conservation. Most innovations are aerospace spinoffs: Some of the equipment is now commercially available; other systems are expected to be in production within a few years. Around 1980, a Tech House-type of home could be built for $45-50,000 (1 976 dollars). It is estimated that the homeowner would save well over $20,000 (again 1976 dollars) in utility costs over the average mortgage span of 20 years.

    2013-08-01

    Full Text Available Strongly interacting gases of ultracold fermions have become an amazingly rich test-bed for many-body theories of fermionic matter. Here we present our recent experiments on these systems. Firstly, we discuss high-precision measurements on the thermodynamics of a strongly interacting Fermi gas across the superfluid transition. The onset of superfluidity is directly observed in the compressibility, the chemical potential, the entropy, and the heat capacity. Our measurements provide benchmarks for current many-body theories on strongly interacting fermions. Secondly, we have studied the evolution of fermion pairing from three to two dimensions in these gases, relating to the physics of layered superconductors. In the presence of p-wave interactions, Fermi gases are predicted to display toplogical superfluidity carrying Majorana edge states. Two possible avenues in this direction are discussed, our creation and direct observation of spin-orbit coupling in Fermi gases and the creation of fermionic molecules of 23Na 40K that will feature strong dipolar interactions in their absolute ground state.

    2013-01-01

    Nano-porous polymers of intrinsic microporosity, PIM, have exhibited excellent permeability and selectivity characteristics that could be utilized in an environmentally friendly gas separation process. A full understanding of the mechanism through which these membranes effectively and selectively allow for the permeation of specific gases will lead to further development of these membranes. Three factors obviously influenced the conformational behavior of these polymers, which are the presence of electronegative atoms, the presence of non-linearity in the polymeric backbones (backbone kinks) and the presence of bulky side groups on the polymeric chains. The dipole moment increased sharply with the presence of backbone kinks more than any other factor. Replacing the fluorine atoms with bulky alkyl groups didn't influence the dipole moment greatly indicating that the size of the side chains had much less dramatic influence on the dipole moment than having a bent backbone. Similarly, the presence of the backbone kinks in the polymeric chains influenced the polymeric chains to assume less extended configuration causing the torsional angles around the interconnecting bonds unable to cross the high potential energy barriers. The presence of the bulky side groups also caused the energy barriers of the cis-configurations to increase dramatically, which prevented the polymeric segments from experiencing full rotation about the connecting bonds. For these polymers, it was clear that the fully extended configurations are the preferred configurations in the absence of strong electronegative atoms, backbones kinks or bulky side groups. The addition of any of these factors to the polymeric structures resulted in the polymeric chains being forced to assume less extended configurations. Rather interestingly, the length or bulkiness of the side groups didn't affect the end-to-end distance distribution to a great deal since the presence of quite large bulky side chain such as the

    The Norwegian government wants to establish in 2006 a market for trading with green certificates which will be issued to producers of new renewable electricity. These certificates will be sold to the consumers, which will be instructed to by a certain amount of green electricity. In 2005 a market will be established for trading with emission quotas of greenhouse gases; in this market, power producers and other industry that emits greenhouse gases must buy emission permits. Some experts, however, say that a market for trading with green certificates may at worst give less production of green electricity, counter to the intention. But a quota system may indirectly increase the production of green electricity, and at the same time one avoids many of the inconveniences involved in a green certificate market

    1996-01-01

    For a country like Algeria, fuel gases represent an important economical challenge. To answer the increasing energy demand in the transportation sector, the use of fuel gases allows to preserve the petroleum reserves and to create specific industrial structures devoted to LPG-f (liquefied petroleum gas-fuel) and NGV (natural gas for vehicles). This paper presents the energy policy of Algeria, its reserves, production, and exportations of hydrocarbons and the internal rational use of energy sources according to its economic and environmental policy and to its internal needs. The energy consumption of Algeria in the transportation sector represents 2/3 of the petroleum products consumed in the internal market and follows a rapid increase necessary to the socio-economic development of the country. The Algerian experience in fuel gases is analysed according to the results of two successive experimentation periods for the development of NGV before and after 1994, and the resulting transportation and distribution network is described. The development of LPG-f has followed also an experimental phase for the preparation of regulation texts and a first statement of the vehicles conversion to LPG-f is drawn with its perspectives of development according to future market and prices evolutions.

    Full Text Available We show that the thermodynamics of ideal gases may be derived solely from the Democritean concept of corpuscles moving in vacuum plus a principle of simplicity, namely that these laws are independent of the laws of motion, aside from the law of energy conservation. Only a single corpuscle in contact with a heat bath submitted to a z and t-invariant force is considered. Most of the end results are known but the method appears to be novel. The mathematics being elementary, the present paper should facilitate the understanding of the ideal gas law and of classical thermodynamics even though not-usually-taught concepts are being introduced.

    GWS takes plans for a new home and subjects them to intensive computerized analysis that does 10,000 calculations relative to expected heat loss and heat gain, then provides specifications designed specifically for each structure as to heating, cooling, ventilation and insulation. As construction progresses, GWS inspects the work of the electrical, plumbing and insulation contractors and installs its own Smart House Radiant Barrier. On completion of the home, GWS technicians use a machine that creates a vacuum in the house and enables computer calculation of the air exchanged, a measure of energy efficiency. Key factor is the radiant barrier, borrowed from the Apollo program. This is an adaptation of a highly effective aluminized heat shield as a radiation barrier holding in or keeping out heat, cold air and water vapor.

    The monitoring of leak releases from ventilation stack of NPP requires a system by several orders more sensitive then currently used radiometer Kalina, designed to cover the range up to a design-based accident. To reach this goal a noble gases monitor with a germanium detector (MPVG) has been developed. It enables nuclide selective monitoring of current value of volume activity of particular nuclides in ventilation stack and daily releases of noble gases (balancing). MPVG can be viewed as a system build of three levels of subsystem: measuring level; control level; presentation level. Measuring level consists of gamma-spectroscopy system and operational parameters monitoring unit (flow rate, temperature, humidity). Control level provides communication between presentation and measuring level, acquisition of operational parameters and power supply. The presentation level of MPVG enables: 1) the measured data storage in predetermined time intervals; 2) the presentation of measured and evaluated values of radiation characteristics. The monitored radionuclides - default set: argon-41, krypton-85m, krypton-87, krypton-88, krypton-89, xenon-131m, xenon-133, xenon-133m, xenon-135, xenon-135m, xenon-137 and xenon-138.

  7. Green thunderstorms

    Science.gov (United States)

    Gallagher, Frank Woolsey, III

    Many people around the world have observed green light apparently emanating from severe thunderstorms, but until recently there has been no scientific study of the phenomenon. Green thunderstorms have been observed from time to time in association with deep convection or severe weather events. Some skeptics who have not personally observed a green thunderstorm suggest that they are some kind of illusion. The existence of green thunderstorms has been objectively demonstrated by recording spectra of light from thunderstorms using a handheld spectrophotometer. During the spring and summer of 1995 and the spring of 1996 numerous storms were observed and spectra of the light emanating from these storms were recorded. Observations were made both at the ground and aboard research aircraft. Furthermore, time series of spectra were recorded as the observed color of some storms changed from dark blue to a bluish-green. Several hypotheses have been advanced to explain the occurrence of green light in connection with severe storms. Fankhauser gave some observational support to the belief that green light from thunderstorms is possible and believed that the source of the light is from the blue sky penetrating thin regions in the clouds. Fraser believes that light from the setting sun, in combination with the process of scattering by atmospheric molecules, creates the green light associated with severe weather and the thunderstorm acts only as a black backdrop. Unfortunately, no cloud illuminated by the sun is black and the green airlight produced by the Fraser theory is in reality overwhelmed by light reflected by the cloud. Often the unusual coloration has been attributed to hail or to reflection of light from foliage on the ground. The quantitative measurements made during the observation period fail to support these assumptions. We have observed thunderstorms to be green over ground that was not green and we have observed blue thunderstorms over ground that was green

    When exploring the correlation between municipal solid waste management and green house gas emission, the volume and physical composition of the waste matter must be taken into account. Due to differences in local environments and lifestyles the quantity and composition of waste often vary. This leads to differences in waste treatment methods and causes different volumes of greenhouse gases (GHGs), highlighting the need for local research. In this study the Life Cycle Inventory method was used with global warming indicator GHGs as the variables. By quantifying the data and adopting a region-based approach, this created a model of household MSWM in Taipei City, a metropolitan region in Taiwan. To allow analysis and comparison a compensatory system was then added to expand the system boundary. The results of the analysis indicated that out of all the solid waste management sub-models for a function unit, recycling was the most effective method for reducing GHG emissions while using kitchen food waste as swine feeding resulted in the most GHG emissions. As for the impact of waste collection vehicles on emissions, if the efficiency of transportation could be improved and energy consumption reduced, this will help solid waste management to achieve its goal of reducing GHG emissions

By quantifying the data and adopting a region-based approach, this created a model of household MSWM in Taipei City, a metropolitan region in Taiwan. To allow analysis and comparison a compensatory system was then added to expand the system boundary. The results of the analysis indicated that out of all the solid waste management sub-models for a function unit, recycling was the most effective method for reducing GHG emissions while using kitchen food waste as swine feeding resulted in the most GHG emissions. As for the impact of waste collection vehicles on emissions, if the efficiency of transportation could be improved and energy consumption reduced, this will help solid waste management to achieve its goal of reducing GHG emissions.

  15. Canonical partition functions: ideal quantum gases, interacting classical gases, and interacting quantum gases

    2018-02-01

    In statistical mechanics, for a system with a fixed number of particles, e.g. a finite-size system, strictly speaking, the thermodynamic quantity needs to be calculated in the canonical ensemble. Nevertheless, the calculation of the canonical partition function is difficult. In this paper, based on the mathematical theory of the symmetric function, we suggest a method for the calculation of the canonical partition function of ideal quantum gases, including ideal Bose, Fermi, and Gentile gases. Moreover, we express the canonical partition functions of interacting classical and quantum gases given by the classical and quantum cluster expansion methods in terms of the Bell polynomial in mathematics. The virial coefficients of ideal Bose, Fermi, and Gentile gases are calculated from the exact canonical partition function. The virial coefficients of interacting classical and quantum gases are calculated from the canonical partition function by using the expansion of the Bell polynomial, rather than calculated from the grand canonical potential.

  16. Economic Hazardous Gases Management for SOX Removal from Flue Gases

    Hazardous gases emerging from industries accumulate as pollutants in air and falls as acid rains resulting also in water and soil pollution. To minimize environmental pollution, the present process is suggested in order to desulfurize flue gases resulting from burning fuel oil in a 100/MWh steam power plant. The process makes use of the cheap Ca C O 3 powder as the alkaline material to sequistre the sulphur oxide gases. The resulting sulphur compounds, namely calcium sulphate and gypsum have a great market demand as reducing and sulphiting agents in paper industry and as an important building material. About 44000 ton of gypsum could be produced yearly when treating flue gases resulting from a 100 MWh unit burning fuel oil. Feasibility study shows that a great return on investment could be achieved when applying the process. 1 fig

  17. SETHI HAVELI, AN INDIGENOUS MODEL FOR 21ST CENTURY ‘GREEN ARCHITECTURE’

    Directory of Open Access Journals (Sweden)

    2010-03-01

    Full Text Available In the 21st century, there has been a growing concern for the degradation of the environment from large quantities of CO2 and green house gases, produced by the building industry. This led to the concept of ‘Green Architecture’, which aims to reduce the environmental impact of buildings through energy efficient designs and healthy indoor environment. In the context of Pakistan, our current practices in architecture are based on Western standards, leading to a growing dependence on fossil fuels and resulting in rapid environmental degradation. Rapoport (Rapoport,1969 states that, modern solutions to climatic problems often do not work, and homes are made bearable by means of mechanical means whose cost sometimes exceeds that of the building shell. Before the import of the Western model for architecture, vernacular architecture provided energy efficient and sustainable spaces. Pearson states that, the new importance of vernacular building is that it has vital ecological lessons for today (Pearson, 1994. In the current scenario, the study and analysis of indigenous architecture can help in developing a home-grown and workable model for ‘Green Architecture’ of 21st century Pakistan. In this paper the climate responsiveness and appropriateness of the Sethi haveli, Peshawar, are analyzed in order to understand the indigenous responses to the issues of environmental comfort. The focus of the study will be the courtyard and how it provides thermal comfort and day-lighting to the building.

  18. Avalanches in insulating gases

    International Nuclear Information System (INIS)

    Verhaart, H.F.A.

    1982-01-01

    Avalanches of charged particles in gases are often studied with the ''electrical method'', the measurement of the waveform of the current in the external circuit. In this thesis a substantial improvement of the time resolution of the measuring setup, to be used for the electrical method, is reported. The avalanche is started by an N 2 -laser with a pulse duration of only 0.6 ns. With this laser it is possible to release a high number of primary electrons (some 10 8 ) which makes it possible to obtain sizeable signals, even at low E/p values. With the setup it is possible to analyze current waveforms with a time resolution down to 1.4 ns, determined by both the laser and the measuring system. Furthermore it is possible to distinguish between the current caused by the electrons and the current caused by the ions in the avalanche and to monitor these currents simultaneously. Avalanche currents are measured in N 2 , CO 2 , O 2 , H 2 O, air of varying humidity, SF 6 and SF 6 /N 2 mixtures. Depending on the nature of the gas and the experimental conditions, processes as diffusion, ionization, attachment, detachment, conversion and secondary emission are observed. Values of parameters with which these processes can be described, are derived from an analysis of the current waveforms. For this analysis already published theories and new theories described in this thesis are used. The drift velocity of both the electrons and the ions could be easily determined from measured avalanche currents. Special attention is paid to avalanches in air becasue of the practical importance of air insulation. (Auth.)

  19. Noble gases solubility in water

    International Nuclear Information System (INIS)

    Crovetto, Rosa; Fernandez Prini, Roberto.

    1980-07-01

    The available experimental data of solubility of noble gases in water for temperatures smaller than 330 0 C have been critically surveyed. Due to the unique structure of the solvent, the solubility of noble gases in water decreases with temperature passing through a temperature of minimum solubility which is different for each gas, and then increases at higher temperatures. As aresult of the analysis of the experimental data and of the features of the solute-solvent interaction, a generalized equation is proposed which enables thecalculation of Henry's coefficient at different temperatures for all noble gases.

    International Nuclear Information System (INIS)

    1995-01-01

    From previous articles we have learned about the complexities of our environment, its atmosphere and its climate system. we have also learned that climate change and, therefore global warm and cool periods are naturally occurring phenomena. Moreover, all scientific evidence suggests that global warming, are likely to occur again naturally in the future. However, we have not yet considered the role of the rates of climate change in affecting the biosphere. It appears that how quickly the climate changes may be more important than the change itself. In light of this concern, let us now consider the possibility that, is due to human activity. We may over the next century experience global warming at rates and magnitudes unparalleled in recent geologic history. The following questions are answered; What can we learn from past climates? What do we know about global climates over the past 100 years? What causes temperature change? What are the greenhouse gases? How much have concentration of greenhouse gases increased in recent years? Why are increases in concentrations of greenhouse of concern? What is the e nhanced greenhouse effect ? How can human activity impact the global climate? What are some reasons for increased concentrations of greenhouse gases? What are fossil fuel and how do they transform into greenhouse gases? Who are the biggest emitters of greenhouse gases? Why are canada per capita emissions of greenhouse gases relatively high? (Author)

    2007-11-15

    Between 1999 and 2006, home energy audits were conducted in 770 scattered houses belonging to the Toronto Community Housing Corporation (TCHC). Over the course of the project, 126 houses were retrofitted with energy saving measures based on calculations of the most cost-effective measures. This report outlined the work that was conducted by the contractor, GreenSaver over the course of the project. The report discussed the project players and project execution. It included a profile of audited houses; auditing procedure; house reports; retrofit work; contractor arranging service; and post-retrofit inspections. Comments on retrofit work not carried out were also provided. The report also discussed the results of the project, including energy savings and emission reductions and participant feedback. A summary of the energy efficiency retrofit survey was also presented along with lessons learned. These included the availability of a contingency fund; the importance of tenant involvement; and making arrangements for other repair work. It was concluded that the amount of expected energy savings on space heating bills varied from house to house, and fell between 15 and 74 per cent. The report recommended that tenants and staff in the social housing sector could benefit from a greater awareness of energy issues and its more efficient use, allowing even greater and longer lasting benefits from a project like this. 8 tabs.

    2018-03-01

    Nowadays, the housing demand of young adults in Indonesia is important issues for the sustainable development of the market. Facing differences of life phases, such as marriage, leaving home after graduation, and new job positioning, young adults become the main segment facing constant housing choice decisions in the housing market. In their particular phase of life, young adults have distinct preferences for housing attributes which bring a great influence on their lives in the future. Data was gathered from a survey questionnaire that was answered by 180 young adults in Indonesia, ranging from age 22-33 years. The findings suggest that the green area and view, location, simplicity, home design, and accessibility are the significant parts as housing attributes for young adults’ housing preferences in Indonesia. The effect of these attributes has many consequences such as security, personalization, mood/ambiance, maintenance, interaction, image, flexibility, environmental, economy, durability, convenience, comfort, and circulation. The biggest group of young adults who prefer comfort as their wanted consequences tend to have high preferences on housing attributes of the green area and view, and simplicity.

    This article draws on the concept of residential context of housing and its relationship to health. It considers a bundle of changes through implementation of a housing renewal initiative as part of the Carlton Housing Estate Upgrading Project in Melbourne, Australia. Beyond the quality and appropriateness of the housing, pertinent factors explored include social networks, safety and security, and green open space. Data collection for the research project included in-depth interviews with public housing tenants, private residents, and service providers who live on and service the estate, as well as neighborhood observations and participation in on-site events. A key finding was that the relational processes of how tenants were related to by others-specifically, the way housing was reallocated during the processes of renewal-affected social housing tenants' self-perceived health and well-being.

    Object: To efficiently and safely separate and recover raw gases such as krypton which requires radioactive attenuation by a long term storage. Structure: A mixture of krypton and xenon is separated by liquefaction from raw gases at a first distillation column, using latent heat of liquid nitrogen. The krypton and xenon mixture separated by liquefaction at the first distillation column is separated into krypton and xenon, by controlling operation pressure of a second distillation column at about 3 - 5 atm., using sensible heat of low temperature nitrogen gas discharged from a top of the first distillation column and a condenser.

    The formalism of statistical mechanics of particles slower than light has been considered from the point of view of the application of this formalism for the description of tachyons. Properties of ideal gases of tachyons have been discussed in detail. After finding general formulae for quantum, Bose and Fermi gases the classical limit has been considered. It has been shown that Bose-Einstein condensation occurs. The tachyon gas of bosons violates the third principle of thermodynamics. Degenerated Fermi gas has been considered and in this case the entropy vanishes at zero temperature. Difficulties of formulating covariant statistical mechanics have been discussed

  18. A microscope for Fermi gases

    International Nuclear Information System (INIS)

    Omran, Ahmed

    2016-01-01

    This thesis reports on a novel quantum gas microscope to investigate many-body systems of fermionic atoms in optical lattices. Single-site resolved imaging of ultracold lattice gases has enabled powerful studies of bosonic quantum many-body systems. The extension of this capability to Fermi gases offers new prospects to studying complex phenomena of strongly correlated systems, for which numerical simulations are often out of reach. Using standard techniques of laser cooling, optical trapping, and evaporative cooling, ultracold Fermi gases of 6 Li are prepared and loaded into a large-scale 2D optical lattice of flexible geometry. The atomic distribution is frozen using a second, short-scaled lattice, where we perform Raman sideband cooling to induce fluorescence on each atom while maintaining its position. Together with high-resolution imaging, the fluorescence signals allow for reconstructing the initial atom distribution with single-site sensitivity and high fidelity. Magnetically driven evaporative cooling in the plane allows for producing degenerate Fermi gases with almost unity filling in the initial lattice, allowing for the first microscopic studies of ultracold gases with clear signatures of Fermi statistics. By preparing an ensemble of spin-polarised Fermi gases, we detect a flattening of the density profile towards the centre of the cloud, which is a characteristic of a band-insulating state. In one set of experiments, we demonstrate that losses of atom pairs on a single lattice site due to light-assisted collisions are circumvented. The oversampling of the second lattice allows for deterministic separation of the atom pairs into different sites. Compressing a high-density sample in a trap before loading into the lattice leads to many double occupancies of atoms populating different bands, which we can image with no evidence for pairwise losses. We therefore gain direct access to the true number statistics on each lattice site. Using this feature, we can

    A pilot program was developed to provide the housing industry with a means to field test innovative technologies, products and building systems, and to evaluate their overall performance. Under Canada`s Advanced House Program, ten demonstration houses were designed, built and monitored. Ottawa`s Innova House, was one of the ten houses built for this program. The innovative energy saving features of the house included (1) air distribution with small diameter ducts and an electronically commutated motor, a 2.6 kW grid-connected photovoltaic system, (3) an energy recovery ventilator (ERV) with free-cooling mode, (4) a 94 per cent efficient integrated gas heating and hot water system, (5) airtight drywall construction, (6) CFC-free exterior insulation, (7) a natural-gas-engine heat pump for air conditioning, (8) a prototype sealed combustion gas range and clothes dryer, and (9) a manifold plumbing system to conserve water. It was designed to consume one half of the energy consumed in an R-2000 home and one third of the energy of a conventional house. Several of the mechanical elements did not perform at expected levels, (lower than expected efficiencies from the heating and cooling systems and a malfunctioning ERV), nevertheless, overall performance of the house was still very close to the targets. The construction and operation of the house was described. tabs., figs.

    The report seeks an answer to the question as to the kind of policy decisions (steps) by which preconditions for green growth may be created in Finland. The proposed steps are based on a review of earlier research and studies relating to Finland's key consumption and production systems (food, housing, transport and energy) and to certain path finding countries in terms of the green economy (the Netherlands, Germany, Sweden, Brazil). In addition, the report examines various models by which systemic change towards a green economy may be supported. The report also highlights successful examples of green business activity and measures to promote green growth. Green Growth is defined as low-carbon, resource-efficient economic growth based on safeguarding the functional capacity of ecosystems while promoting wellbeing and social justice. Green growth is considered to have significant worldwide potential, which is currently evident particularly in the rapid growth of cleantech demand. Successful future actors will be more material- and energy-efficient than their competitors, and they will be able to provide services and products flexibly for a low-carbon society. There are opportunities for green growth in all sectors of society. Green growth may consist of an entirely new kind of business activity and create new companies, but there are also opportunities in our traditional energy- and resource-intensive industries. Companies have a key role in growth, but realising green growth also requires changes in consumption. Central, regional and local government will act as facilitators in creating the preconditions for green growth. The report presents a number of policy measures and processes by which Finland can support green growth. Proposals for steps towards green growth include: (A.) Creating preconditions for green growth through a joint vision and political commitment. (B.) Stimulating companies' green growth potential and boosting green demand. (C

    The permeability of gases through uncompressed cork was investigated. More than 100 samples were assessed from different plank qualities to provide a picture of the permeability distribution. A novel technique based on a mass spectrometer leak detector was used to directly measure the helium flow through the central area of small disks 10 mm in diameter and 2 mm thick. The permeability for nitrogen, oxygen, and other gases was measured by the pressure rise technique. Boiled and nonboiled cork samples from different sections were evaluated. An asymmetric frequency distribution ranging 3 orders of magnitude (roughly from 1 to 1000 μmol/(cm·atm·day)) for selected samples without macroscopic defects was found, having a peak below 100 μmol/(cm·atm·day). Correlation was found between density and permeability: higher density samples tend to show lower permeability. However, boiled cork showed a mean lower permeability despite having a lower density. The transport mechanism of gases through cork was also examined. Calculations suggest that gases permeate uncompressed cork mainly through small channels between cells under a molecular flow regime. The diameter of such channels was estimated to be in the range of 100 nm, in agreement with the plasmodesmata size in the cork cell walls.

  6. Essays on Housing Markets

    DEFF Research Database (Denmark)

    Bäckman, Claes

    In Denmark and in many countries around the world, housing markets are of considerable importance for households and policy-makers alike. As the boom and bust in the US and Danish housing market so aptly demonstrated, disruptions in the housing market potentially have wide-ranging consequences...... for individual households and for the aggregate economy. Housing is important because we all have to live somewhere, but also because it serves as a considerable source of both wealth and debt. As such, housing market policy can not only create vast benefits for many, but can also have substantial negative...... impacts for all, and should therefore be a topic of major interest for economists and policy makers alike. This Ph.D. thesis, entitled “Essays on Housing Markets”, analyzes the Danish housing market during the 2000s, with a focus on how policy changes affected house prices and how changes in house prices...

    According to Catholic social teaching, housing is not a commodity but a human right. To ensure that all people--especially low-income elderly and other vulnerable populations--have access to affordable housing, the church has established a variety of programs, services, and advocacy efforts. Much of this work is based on key concepts: preserving existing housing stock, creating new programs to provide more options for the underserved, empowering residents and communities to deal with housing issues, establishing partnerships to make organizations' efforts more successful, making housing affordable, and ending discrimination in housing. Although church ministries, community groups, the private sector, and other players must work together to find solutions to the housing crisis, federal leadership is essential. Especially with the housing affordability gap growing and the U.S. population aging, the federal government must provide the resources, leadership, and direction for effective housing solutions.

    Historically, early identification and characterization of adverse effects of industrial chemicals was difficult because conventional toxicological test methods did not meet R&D needs for rapid, relatively inexpensive methods amenable to small amounts of test material. The pharmaceutical industry now front-loads toxicity testing, using in silico, in vitro, and less demanding animal tests at earlier stages of product development to identify and anticipate undesirable toxicological effects and optimize product development. The Green Chemistry movement embraces similar ideas for development of less toxic products, safer processes, and less waste and exposure. Further, the concept of benign design suggests ways to consider possible toxicities before the actual synthesis and to apply some structure/activity rules (SAR) and in silico methods. This requires not only scientific development but also a change in corporate culture in which synthetic chemists work with toxicologists. An emerging discipline called Green Toxicology (Anastas, 2012) provides a framework for integrating the principles of toxicology into the enterprise of designing safer chemicals, thereby minimizing potential toxicity as early in production as possible. Green Toxicology`s novel utility lies in driving innovation by moving safety considerations to the earliest stage in a chemical`s lifecycle, i.e., to molecular design. In principle, this field is no different than other subdisciplines of toxicology that endeavor to focus on a specific area - for example, clinical, environmental or forensic toxicology. We use the same principles and tools to evaluate an existing substance or to design a new one. The unique emphasis is in using 21st century toxicology tools as a preventative strategy to "design out" undesired human health and environmental effects, thereby increasing the likelihood of launching a successful, sustainable product.

    2017-10-01

    Well established and maintained green areas have a key role on reaching the high quality of life and sustainability in urban environments. Therefore, green areas must be carefully accounted and evaluated in the urban planning affairs. In this context, the European Green Capitals, which attach a great importance to the green areas, have a great potential to act as a role model for both small and big cities in all around the world. These leading cities (chronologically, Stockholm, Hamburg, Vitoria-Gasteiz, Nantes, Copenhagen, Bristol, Ljubljana, Essen and Nijmegen) are inspiring for the other cities which seek to achieve more sustainable and environmentally friendly places through green areas. From this point of view, the aim of this paper was to investigate the green areas of the European Green Capitals. The paper covered whole European Green Capitals, and the application form of each Green Capital was used as a primary data source. Consequently, the paper put forwarded that the European Green Capitals have considerably large amount and high proportion of green areas. Further, these cities provide an excellent access to the public green areas. As a result of abundant provision and proper distribution, the almost all citizens in most of the Green Capitals live within a distance of 300 meters to a green area. For further researches, the paper suggested that these green capitals should be investigated in terms of their efforts, measures, goals and plans, policies and implications to administer, to protect, to enhance and to expand the green areas.

    High technology and environment applications of the Rare Earth Elements (REE) have grown dramatically in diversity and importance over the past few decades. The REE forms largest economical coherent group in the periodic table. The versatility and specialty of the REE has given them a level of technological, environment and economical importance. As technological applications of REE have multiplied over the past several decades, the demand for them has increased dramatically. The green energy is the segment, which is largely contributed in its performance by the REE. The increasing concern about the impact of green house gases around the globe has made countries to explore clean energy technologies to reduce emissions. India has ambitious plans for generating solar power of 30,000 MW and wind energy of 50,000 MW by 2013. Critical component with respect to wind energy is the high strength rare earth permanent magnet, while in hybrid electrical motors REEs like lanthanum are used in LiMH battery pack

  1. Soliton Gases and Generalized Hydrodynamics

    Science.gov (United States)

    Doyon, Benjamin; Yoshimura, Takato; Caux, Jean-Sébastien

    2018-01-01

    We show that the equations of generalized hydrodynamics (GHD), a hydrodynamic theory for integrable quantum systems at the Euler scale, emerge in full generality in a family of classical gases, which generalize the gas of hard rods. In this family, the particles, upon colliding, jump forward or backward by a distance that depends on their velocities, reminiscent of classical soliton scattering. This provides a "molecular dynamics" for GHD: a numerical solver which is efficient, flexible, and which applies to the presence of external force fields. GHD also describes the hydrodynamics of classical soliton gases. We identify the GHD of any quantum model with that of the gas of its solitonlike wave packets, thus providing a remarkable quantum-classical equivalence. The theory is directly applicable, for instance, to integrable quantum chains and to the Lieb-Liniger model realized in cold-atom experiments.

    2012-01-01

    Highlights: ► The PVT-vibrating wire technique and PVT-scanning transitiometry. ► Polymer swelling with measured gas sorption and gas–polymer interaction energies. ► Experimental measurements up to 373 K and 100 MPa. ► Hydrostatic and plasticization effects under high pressure gas and induced T g -shifts. ► Thermodynamic study of the (gas + polymer) systems polystyrene with CO 2 , N 2 , and freons. - Abstract: Foaming constitutes one of the most important industrial activities in polymer engineering to produce efficient thermal insulating materials. In particular, rigid insulating boards are produced worldwide on a large scale using blowing agents which eventually are released in the environment where they adversely impact the natural friendly stratospheric ozone layer. Concomitantly, the chemicals used as blowing agents contribute to the creation of the unfriendly tropospheric ozone layer generating the disastrous green house effect around our planet. The traditional foaming intermediates currently named freons, like chlorofluorocarbons (CFCs) currently used as blowing agents as well as the hydrochlorofluorocarbons (HCFCs) often considered as alternative blowing agents, must be banned from industrial processes and new (friendly) foaming agents have to be suggested and evaluated in terms of both easy engineering and environmental neutrality. Undoubtedly thermodynamics plays a major role in assessing the effective capability of those chemicals. Some CFCs still accepted and other possible simple gases like carbon dioxide and nitrogen have been considered. The in-depth thermodynamic investigation has been made possible thanks to new experimental developments to determine gas solubility in polymers and associated swelling as well as the thermodynamic properties of (gas + polymer) systems, including the thermophysical properties of polymers under gas sorption. Pertinent data have been generated for such properties over extended T and p ranges.

    A grand challenge facing government, industry, and academia in the relationship of our technological society to the environment is reinventing the use of materials. To address this challenge, collaboration from an interdisciplinary group of stakeholders will be necessary. Traditionally, the approach to risk management of materials and chemicals has been through inerventions intended to reduce exposure to materials that are hazardous to health and the environment. In 1990, the Pollution Prevention Act encouraged a new tact-elimination of hazards at the source. An emerging approach to this grand challenge seeks to embed the diverse set of environmental perspectives and interests in the everyday practice of the people most responsible for using and creating new materials--chemists. The approach, which has come to be known as Green Chemistry, intends to eliminate intrinsic hazard itself, rather than focusing on reducing risk by minimizing exposure. This chapter addresses the representation of downstream environmental stakeholder interests in the upstream everyday practice that is reinventing chemistry and its material inputs, products, and waste as described in the '12 Principles of Green Chemistry'

    Full Text Available Tourism and other culture-based types of small business, which are the leitmotif in the planning of the Europark Ruardi, are becoming the guiding motif in the spatial development of urban centres that are influenced by dynamic transformation processes. The system should build upon the exploitation of both local and regional environmental features. This would encourage the quest for special environmental features, with an emphasis on their conservation, i.e. sustainable development, and connections in a wider context.The Europark is seen as a new strategic point of the Zasavje Region (the region of the central Sava Valley, which is linked to other important points in a region relevant for tourism. Due to the "smallness" of the region and/or the proximity of such points, development can be fast and effective. The interaction of different activities in space yields endless opportunities for users, who choose their own goals and priorities in the use of space. Four theme areas of the Europark area planning are envisaged. The organisation of activities is based on the composition of the mosaic field patterns, where green fields intertwine with areas of different, existing and new, urban functions. The fields of urban and recreation programmes are connected with a network of green areas and walking trails, along which theme park settings are arranged.

  17. Inadequate housing in Ghana

    Directory of Open Access Journals (Sweden)

    Franklin Obeng-Odoom

    2011-01-01

    Full Text Available Two themes are evident in housing research in Ghana. One involves the study of how to increase the number of dwellings to correct the overall housing deficit, and the other focuses on how to improve housing for slum dwellers. Between these two extremes, there is relatively little research on why the existing buildings are poorly maintained. This paper is based on a review of existing studies on inadequate housing. It synthesises the evidence on the possible reasons for this neglect, makes a case for better maintenance and analyses possible ways of reversing the problem of inadequate housing.

  1. Green LPG

    Energy Technology Data Exchange (ETDEWEB)

    Hulteberg, Christian; Brandin, Jan; Leveau, Andreas (Biofuel-Solution AB, Limhamn (Sweden))

    2010-12-15

    The use of energy gases with renewable origins will become important with diminishing fossil resources. This as the infrastructure of the gaseous fuels is well built out and the distribution networks already exist. LPG is one of the most versatile fuels around, perfect for rural areas and in many other applications. The fossil origin of the fuel will, in today's climate and environmental debate, however position it as a thing of the past and not part of the future energy supply. The technology and development performed under this and previous programs with the Swedish Gas Centre will however suggest a way to bridge this conception and make LPG a part of the future energy mix. This report constitutes the results from the development performed under the SGC program 210 and is aimed at verifying the results from the previous SGC program 198, proving the concept for producing propane from renewable glycerol. Attractive and potentially profitable LPG premium segments that can be reached by producing bio-propane would be the autogas market. Another attractive segment to target is the outdoor and camping segment, where there already exist awareness for nature and the environment. A third interesting segment is in small-scale heat or combined heat and power generation, where a premium price can be reaped for renewable energy as well as the addition of LPG to biogas. Another important aspect of the renewable LPG is that it motivates external stakeholders, such as local, regional, national and international governments as well as environmental and other lobby groups to consider LPG a part of the future energy mix and not a thing of the past. A good starting point for two and three carbon energy gases is glycerine, with its three carbon backbone. The reason for focusing on glycerine is its benign chemical nature, it is: - Harmless from a toxic standpoint; - Chemically inert; - Non-corrosive; - Relatively high energy density; - Zero carbon dioxide emissions. It is also

    Results of a workshop on the title subject (25 March 1997) are presented. The purpose of the workshop was to transfer knowledge and disseminate information about the fiscal options and regulations in the Netherlands to invest in environment-friendly projects (EIA, VAMIL, Regeling Groenprojecten). Next to presentations of representatives of a bank, involved in green funding projects, a public utility and a housing corporation, four cases were discussed in which green investment options for solar energy system projects have been evaluated: (1) large-scale solar boiler project (150 m 2 ) in a health care home (utility building); (2) large-scale photovoltaic (PV) project (1000 m 2 ) in the facade of a new office building; (3) application of solar water heaters in a housing project of 1000 private property houses; and (4) a cluster project of 100 private property houses with a 5 m 2 roof-integrated PV-system for each house

  3. Influence of the gray gases number in the weighted sum of gray gases model on the radiative heat exchange calculation inside pulverized coal-fired furnaces

    Full Text Available The influence of the number of gray gases in the weighted sum in the gray gases model on the calculation of the radiative heat transfer is discussed in the paper. A computer code which solved the set of equations of the mathematical model describing the reactive two-phase turbulent flow with radiative heat exchange and with thermal equilibrium between phases inside the pulverized coal-fired furnace was used. Gas-phase radiative properties were determined by the simple gray gas model and two combinations of the weighted sum of the gray gases models: one gray gas plus a clear gas and two gray gases plus a clear gas. Investigation was carried out for two values of the total extinction coefficient of the dispersed phase, for the clean furnace walls and furnace walls covered by an ash layer deposit, and for three levels of the approximation accuracy of the weighting coefficients. The influence of the number of gray gases was analyzed through the relative differences of the wall fluxes, wall temperatures, medium temperatures, and heat transfer rate through all furnace walls. The investigation showed that there were conditions of the numerical investigations for which the relative differences of the variables describing the radiative heat exchange decrease with the increase in the number of gray gases. The results of this investigation show that if the weighted sum of the gray gases model is used, the complexity of the computer code and calculation time can be reduced by optimizing the number of gray gases.

    It all started with two words. Climate change. The carbon dioxide trading scheme, which was the politicians' idea on solving the number one global problem, followed. Four years ago, when the project was begun, there was no data for project initiation. Quotas for polluters mainly from energy production and other energy demanding industries were distributed based on spreadsheets, maximum output and expected future development of economies. Slovak companies have had a chance to profit from these arrangements since 2005. Many of them took advantage of the situation and turned the excessive quotas into an extraordinary profit which often reached hundreds of million Sk. The fact that the price of free quotas offered for sale dropped basically to 0 in 2006 only proved that the initial distribution was too generous. And the market reacted to the first official measurements of emissions. Slovak companies also contributed to this development. However, when planning the maximum emission volumes for 2008-2012 period, in spite of the fact that actual data were available, their expectations were not realistic. A glance at the figures in the proposal of the Ministry of Environment is sufficient to realize that there will be no major change in the future. And so for many Slovak companies business with a green future will remain green for the next five years. The state decided to give to selected companies even more free space as far as emissions are concerned. The most privileged companies can expect quotas increased by tens of percent. (author)

    2014-09-01

    Full Text Available No prior literature explores the influence of green transformational leadership on green performance, thus, this study develops a novel research framework to fill the research gap. This study investigates the influence of green transformational leadership on green performance and discusses the mediation effects of green mindfulness and green self-efficacy by means of structural equation modeling (SEM. The results indicate that green transformational leadership positively influences green mindfulness, green self-efficacy, and green performance. Moreover, this study demonstrates that the positive relationship between green transformational leadership and green performance is partially mediated by the two mediators: green mindfulness and green self-efficacy. It means that green transformational leadership can not only directly affect green performance positively but also indirectly affect it positively through green mindfulness and green self-efficacy. Therefore, firms need to raise their green transformational leadership, green mindfulness, and green self-efficacy to increase their green performance.

  8. Investigation of Sustainable Housing Criteria

    Full Text Available Recently, much attention has been paid to sustainable development in cities. The quality of human life is directly related to environmental quality. Because many people live in cities as a place of social, economic and cultural relationships, certain issues such as environmental crises, energy, air and noise pollution and traffic jams are some of the factors that can alter the quality of human life. Therefore, in order to improve the quality of human life, attention to sustainable development (or sustainability in cities is proposed. Sustainable building has a comprehensive significance that begins with the conception of negative and positive impacts on the environment. Several descriptions of sustainable or green buildings have been created; however, they all pursue one goal, which is to create sustainable urban developments and protection of the environment. The quality of indoor environments, materials, and energy consumption, water usage, the impact of building construction processes and building maintenance are some of the factors that affect the environment and sustainability. Sustainable building is an attempt to relieve the minus impacts on the environment that occur during a building’s lifetime. This research investigates the important factors that have relevance to green buildings and introduces several criteria of sustainable housing.

    International Nuclear Information System (INIS)

    Welsh, L.

    1998-01-01

    A discussion about generating electricity from renewable energy sources was presented. The Environment Canada/ENMAX green power contract stipulates that in order for electricity to quality as green power it must be generated by renewable energy sources such as wind, solar, combustion of sustainably produced biomass, or run-of-the-river hydroelectricity. The contract also includes emissions reduction credit (ERC) ownership for greenhouse gases, sulphur dioxide, nitrogen oxides, particulates, and toxics. By using green power in some of its own facilities the government demonstrates its support for renewable energy sources, and provides the initial market for the industry to build up its capacity to service larger markets. The emission reduction credits 'earned' could be added to the government inventories as environmental assets

    Szirmai, Gergely; Szepfalusy, Peter; Kis-Szabo, Krisztian

    2003-01-01

    The finite temperature Green's function technique is used to calculate the energies and damping rates of the elementary excitations of homogeneous, dilute, spin-1 Bose gases below the Bose-Einstein condensation temperature in both the density and spin channels. For this purpose a self-consistent dynamical Hartree-Fock model is formulated, which takes into account the direct and exchange processes on equal footing by summing up certain classes of Feynman diagrams. The model is shown to satisfy the Goldstone theorem and to exhibit the hybridization of one-particle and collective excitations correctly. The results are applied to gases of 23 Na and 87 Rb atoms

    Reports from interdisciplinary areas including microbiology, biochemistry, animal nutrition, agricultural engineering and economics are integrated in this proceedings. The major theme of this book is environmental preservation by controlling release of undesirable greenhouse gases to realize the sustainable development of animal agriculture. Technology exists for the effective collection of methane generated from anaerobic fermentation of animal effluent and its use as a biomass energy source. Fossil fuel consumption can be reduced and there can be increased use of locally available energy sources. In addition, promoting environmentally-conscious agriculture which does not rely on the chemical fertilizer can be realized by effective use of animal manure and compost products.

    A nationwide investigation of radon levels in Syrian houses was carried out during the period 1991-1993. Passive radon diffusion dosemeters using polycarbonate detectors were distributed in houses all over Syria. Detectors were subjected to electrochemical etching to reveal latent tracks of alpha particles. The mean radon concentration in Syrian houses was found to be 45 Bq m -3 with some values several times higher. This investigation indicated that there were a few houses in Syria that require remedial action. Most houses that have high levels of radon were found in the southern area, especially in the Damascus governorate. The study also indicated that radon concentrations were higher in old houses built from mud with no tiling. (author)

  17. Growing community : rooftop gardens for affordable housing

    Weeks, K.N. [California Univ., Berkeley, CA (United States)

    2007-07-01

    This paper reviewed the processes used in recently designed affordable housing roof garden projects in California, Montana and Georgia. Gardens create a sense of community through shared space and social interactions. As such, roof gardens can give residents of affordable housing the opportunity to experience the community-fostering benefits of gardening, with the added advantages of potentially lower energy bills and wastewater fees. The factors that should be considered in planning, design, construction and maintenance of roof gardens for affordable housing were also outlined. As places of refuge, gardens help people relax and promote healing, which is particularly important for physical, emotional, social and economic well-being. For the many residents of affordable housing who earn less than 50 per cent of the area median income, gardens offer a venue for establishing relationships with neighbours, many of whom they might otherwise never meet. They also offer a means to improved nutrition and food security, education and positive recreation for youth, and better aesthetic surroundings. While motivations for choosing green roofs varied widely across the projects, affordability was linked to 3 main areas, namely saving costs in design, construction and operations; getting the roof to generate funding; and, improving the quality of life in affordable housing. 17 refs., 12 figs.

    Renewable energy is an important piece of the puzzle in meeting growing energy demands and mitigating climate change, but the potentially adverse effects of such technologies are often overlooked. Given that climate and ecology are inextricably linked, assessing the effects of energy technologies requires one to consider their full suite of global environmental concerns. We review here the ecological impacts of three major types of renewable energy - hydro, solar, and wind energy - and highlight some strategies for mitigating their negative effects. All three types can have significant environmental consequences in certain contexts. Wind power has the fewest and most easily mitigated impacts; solar energy is comparably benign if designed and managed carefully. Hydropower clearly has the greatest risks, particularly in certain ecological and geographical settings. More research is needed to assess the environmental impacts of these 'green' energy technologies, given that all are rapidly expanding globally. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Industry in Quebec is reported to be taking measures to reduce their greenhouse gas emissions even before government regulations are imposed. In 2002, close to 89 million tonnes of greenhouse gases were dispersed into the atmosphere in Quebec, two and one half million tonnes more than in 1990, the reference year for the Kyoto Protocol. To meet the obligations imposed by the Kyoto Protocol objectives Quebec must reduce its greenhouse gas emissions by 5.2 per cent , or 6.5 million tonnes to help Canada to reach its stated emission reduction objective between now and 2012. All sectors of the economy, industry, buildings, agriculture, transport, must do their part in cutting back on their emissions. This article discusses a variety of initiatives that could be taken to move us all toward the goal. Roof gardens, such as the one installed at the Hotel Hilton Bonaventure in Montreal, increased use of solar energy as exemplified by one of the largest solar capture panels facility installed at its Montreal plant by Canadair Bombardier, an innovative use of electric refrigeration in its 1,600 ice cream trucks fleet by a large ice cream supplier, which allows each truck to reduce its annual emission by 16.38 tonnes, for a fleet total of 10,000 tonnes of greenhouse gases. Other examples cited include recovery and reuse of methane from a neighbouring landfill by the Cascade Paper Mill in Sainte-Jerome, a pig farm in Saint-Isidore de Beauce that plans to 'wash' the waste produced by its 2,000 pigs, removing 90 per cent of the phosphates in the process, prior to discharging the enriched manure on the neighbouring fields, a cheese factory in Lac Saint-Jean reducing its water consumption by 83 per cent through recycling, using 11 per cent less natural gas and emitting 31 tonnes less carbon dioxide in the process, and the solar heating pilot project in a rental housing complex in Montreal, which is expected to reduce greenhouse gas emissions by .065 to 0.95 tonne per

    By means of the Green Deal, the Dutch government aims to accelerate the sustainability of the economy by supporting initiatives in the field of energy, water, feedstocks and mobility. Businesses, organizations and authorities have submitted over 200 proposals, of which 59 have been selected and elaborated into Green Deals. A previous note has mapped the additional effects of the Green Deals on the share of renewable energy and the emission of non-ETS greenhouse gases. This note addressed questions such as: Which positive effects may occur?; Do the Green Deals lead to additional activities?; Can the results be scaled up?; Can the effects be measured?; Which effects can be observed for renewable energy and emissions in 2020? The note subsequently discusses in which ways the positive effects of the Green Deals could be enhanced. [nl

    2005-07-01

    Livingroofs.org is a non-profit organization that was established to provide a resource for promoting green roofs in the United Kingdom (UK). Current policies in the UK related to the planning and development of green roofs are a constraint to their uptake. The emerging emphasis on sustainable development is bringing about a revision of planning policies that may make green roofs more desirable. However, green roof design standards are still being developed by a largely unmonitored industry furthering a product with which most people are unfamiliar. This paper reviewed a number of issues that need to be addressed to assist in the wider adoption of green roofs, including increased awareness; an identification of the real benefits of green roofs; guidance and research; planning policies; fiscal incentives; industry standards and codes of practice. Details of the current policy frameworks for construction, urban design and climate change were also outlined. Two specific projects were reviewed to provide an insight into the way in which Livingroofs.org intends to promote green roof technology: a roof owned by the Birmingham city council and a collaboration with a Swiss partner to design a roof for the Komodo Dragon House at the London Zoo. It was concluded that there is now a real likelihood that the widespread adoption of green roofs will occur in the UK within the next 5 years, both in terms of new developments and the vast potential for retro-fitting on existing buildings. 47 refs., 2 tabs.

    2016-06-01

    Full Text Available The conservative family lifestyle in the Ottoman State affected the ways that houses were planned and decorated. Different decorative programs emerged with major differences in each period. New techniques and styles began to be seen in the 18th century thanks to the influence of the West. This article will focus on the decoration of Dedebayrak House in Ankara. Decoration in the architecture found within the boundaries of Ankara consist mostly of geometrical or floral decorations and various inscriptions. The Dedebayrak House not only has these kind of decorations, but also it has these decorations in its architectural descriptions, so it makes this house the only one to have survived in Ankara. Moreover, this building is especially important as the décor included work belonging to Nakkaş Mustafa. However, these decorative features do not remain today. The situation in Turkey is such that architecture is not conserved, which leads to many historically important buildings vanishing. Neither local authorities, nor the owner of these buildings look after these buildings properly, leading their specific historical features to be lost. This situation both damages the urban fabric and harms the historical heritage of the city. Therefore, decorative features in the building will be analysed both on their own and compared to other buildings in Ankara in order to create an overall picture.

    The term house doctor may be generalized to include persons skilled in the use of instruments and procedures necessary to identify, diagnose, and correct indoor air quality problems as well as energy, infiltration, and structural problems in houses. A radon house doctor would then be a specialist in radon house problems. Valuable experience in the skills necessary to be developed by radon house doctors has recently been gained in an extensive radon monitoring and mitigation program in upstate New York sponsored by Niagara Mohawk Power Corporation and the New York State Energy Research and Development Authority. These skills, to be described in detail in this paper, include: (i) the use of appropriate instruments, (ii) the evaluation of the symptoms of a radon-sick house, (iii) the diagnostic procedures required to characterize radon sources in houses, (iv) the prescription procedures needed to specify treatment of the problem, (v) the supervision of the implementation of the treatment program, (vi) the check-up procedures required to insure the house cured of radon problems. 31 references, 3 tables

  18. Noble gases in nuclear medicine

    1973-01-01

    Radioactive noble gases have made a significant contribution to diagnostic nuclear medicine. In the area of regional assessment of pulmonary function, 133 Xe has had its greatest clinical impact. Following a breath of 133 Xe gas, pulmonary ventilation can be measured using a scintillation camera or other appropriate radiation detector. If 133 Xe dissolved in saline is injected intravenously, both pulmonary capillary perfusion and ventilation can be measured since 90 percent of the highly insoluble xenon escapes into the alveoli during the first passage through the lungs. Radionuclide pulmonary function tests provide the first qualitative means of assessing lung ventilation and blood flow on a regional basis, and have recently been extended to include quantification of various parameters of lung function by means of a small computer interfaced to the scintillation camera. 133 Xe is also used in the measurement of organ blood flow following injection into a vessel leading into an organ such as the brain, heart kidneys, or muscles

  20. Energy efficiency and greenhouse gases

    International Nuclear Information System (INIS)

    Hamburg, A.; Martins, A.; Pesur, A.; Roos, I.

    1996-01-01

    Estonia's energy balance for 1990 - 1994 is characterized by the dramatic changes in the economy after regaining independence in 1991. In 1990 - 1993, primary energy supply decreased about 1.9 times. The reasons were a sharp decrease in exports of electric energy and industrial products, a steep increase in fuel prices and the transition from the planned to a market-oriented economy. Over the same period, the total amount of emitted greenhouse gases decreased about 45%. In 1993, the decrease in energy production and consumption stopped, and in 1994, a moderate increase occurred (about 6%), which is a proof stabilizing economy. Oil shale power engineering will remain the prevailing energy resource for the next 20 - 25 years. After stabilization, the use of oil shale will rise in Estonia's economy. Oil shale combustion in power plants will be the greatest source of greenhouse gases emissions in near future. The main problem is to decrease the share of CO 2 emissions from the decomposition of carbonate part of oil shale. This can be done by separating limestone particles from oil shale before its burning by use of circulating fluidized bed combustion technology. Higher efficiency of oil shale power plants facilitates the reduction of CO 2 emissions per generated MWh electricity considerably. The prognoses for the future development of power engineering depend essentially on the environmental requirements. Under the highly restricted development scenario, which includes strict limitations to emissions (CO 2 , SO 2 , thermal waste) and a severe penalty system, the competitiveness of nuclear power will increase. The conceptual steps taken by the Estonian energy management should be in compliance with those of neighboring countries, including the development programs of the other Baltic states

  4. City of Austin: Green habitat learning project. A green builder model home project

    1995-12-01

    The purpose of the Year 14 UCETF project was to design and construct a residential structure that could serve as a demonstration facility, training site, and testing and monitoring laboratory for issues related to the implementation of sustainable building practices and materials. The Model Home Project builds on the previous and existing efforts, partially funded by the UCETF, of the City of Austin Green Builder Program to incorporate sustainable building practices into mainstream building activities. The Green Builder Program uses the term {open_quotes}green{close_quotes} as a synonym for sustainability. In the research and analysis that was completed for our earlier reports in Years 12 and 13, we characterized specific elements that we associate with sustainability and, thus, green building. In general, we refer to a modified life cycle assessment to ascertain if {open_quotes}green{close_quotes} building options reflect similar positive cyclical patterns found in nature (i.e. recyclability, recycled content, renewable resources, etc.). We additionally consider economic, human health and synergistic ecological impacts associated with our building choices and characterize the best choices as {open_quotes}green.{close_quotes} Our ultimate goal is to identify and use those {open_quotes}green{close_quotes} materials and processes that provide well for us now and do not compromise similar benefits for future generations. The original partnership developed for this project shifted during the year from a project stressing advanced (many prototypical) {open_quotes}green{close_quotes} building materials and techniques in a research and demonstration context, to off-the-shelf but underutilized {open_quotes}green{close_quotes} materials in the practical social context of using {open_quotes}green{close_quotes} technologies for low income housing. That project, discussed in this report, is called the Green Habitat Learning Project.

    The rises of house price in the market is so drastic that it effects the younger generation nowadays especially young executives and young couples who could not afford to buy their first home. The factors that determine the house price presumably are the interior and exterior structural of the house itself. So to lessen the house price, we have to minimize the usage of wet construction thus the idea of having a sustainable green inner-wall implemented into the house with a flexible floor plan. This concept is user-friendly as it is built on needs and the ownership's affordability. They can design the interior of the house however they want with using minimal cost because it does not involve wet construction.

    Based on Chinese city-level data from 1999 to 2012 and controlling for geological, environmental, and social diversity, this study suggests that credit plays a significant role in driving up house prices after the Great Recession, whereas property prices only influence bank lending before 2008. Local amenities such as higher education, green infrastructure, healthcare, and climate also positively affect house prices. Moreover, the impacts of bank loans on housing prices tend to be related to ...

    As a follow-up activity of the Macedonian First National Communication under the UNFC-CC, Technology Needs Assessment is conducted, evaluating by GACMO model the measures related mainly to energy efficient and renewable energy technologies. An abatement cost curve is constructed and used as an illustrative tool for recognizing priorities in GHG abatement policy. About half of the measures are shown to be of 'win-win' type, reducing 3% of the baseline GHG emissions, while the total reduction which can be achieved by all measures amounts to 20%. For each measure difficulties for implementation are identified, being the highest for the measures with largest GHG abatement potential. Generally, these difficulties include lack of financing and low prospects for attracting foreign investments as well as legislative and administrative barriers. It must be recognized that climate change issues could not be of high priority in a country with economy in transition. Consequently, in our case the main issues which should be integrated within the framework of ongoing transition reforms, in an effort to implement a GHG emission reduction policy, would be: institutional capacity building, attracting foreign investment, emphasis on energy efficiency and considering the switch toward less carbon intensive fuels.

    2006-01-01

    During the 20. Century the great increase of energy uses, nearly all from fossil sources, have brought on more and more significant growth of the CO 2 rate in the atmosphere. As we know, this has produced important environmental effects, which are getting worse and worse. Certainly, the importance of this problem forces the research of various solutions which can reduce or limit CO 2 emissions in atmosphere. Up at the present day, world policies about the reduction of fossil fuel uses, have failed. Consequently the aim could be to develop production cycles which convert the greenhouse CO 2 , recovered from power plant or human activities, into a resource. In fact there are a lot of different cycles that use CO 2 such as physical states: gaseous, liquid, solid and supercritical. In this paper the present and future situation is analysed. After a short examination of different uses of CO 2 , the best innovative and environmental among are studied. A particular CO 2 use (biomass production) has been examinated

  14. Three Smoking Guns Prove Falsity of Green house Warming

    Fong, P.

    2001-12-01

    Three observed facts: 1, the cloud coverage increased 4.1% in 50 years; 2. the precipitation increased 7.8% in 100 years; 3. the two rates are the same. {Interpretation}. 1, By the increased albedo of the clouds heat dissipation is increased 3.98 W/m2 by 2XCO2 time, canceling out greenhouse warming of 4 W/m{2}. Thus no global warming. 2, The precipitation increase show the increased release of latent heat of vaporization, which turns out to be equal to that absorbed by ocean due to increased evaporation by the greenhouse forcing. This all greenhouse heat is used up in evaporation and the warming of the earth is zero. 3, The identity of the two rates double-checked the two independent proofs. Therefore experimentally no greenhouse warming is triply proved. A new branch of science Pleistocene Climatology is developed to study the theoretical origin of no greenhouse warming. Climatology, like mechanics of a large number of particles, is of course complex and unwieldy. If totally order-less then there is no hope. However, if some regularity appears, then a systematic treatment can be done to simplify the complexity. The rigid bodies are subjected to a special simplifying condition (the distances between all particles are constant) and only 6 degrees of freedom are significant, all others are sidetracked. To study the spinning top there is no need to study the dynamics of every particle of the top by Newton's laws through super-computer. It only needs to solve the Euler equations without computer. In climate study the use of super-computer to study all degrees of freedom of the climate is as untenable as the study of the spinning top by super-computer. Yet in spite of the complexity there is strict regularity as seen in the ice ages, which works as the simplifying conditions to establish a new science Pleistocene climatology. See my book Greenhouse Warming and Nuclear Hazards just published (www.PeterFongBook.com). This time the special condition is the presence of a permanent body of ice (thus Pleistocene), and the existence of two thermostats, the polar ice and the clouds, with the specific simplifying condition being the neutral equilibrium condition of phase transition of ice and water. As Boltzmann has done, the equilibrium condition staffs off all trivial degrees of freedom an simplifies the problem. Indeed it is the equilibrium condition that determines no greenhouse warming. The very fact that in the past century no decent theory of ice ages has been developed means that the climate study has missed the essential point(like the Euler equations for the spinning top). The greenhouse warming theory is now worked out as a special case (pp. 145-179) of the ice age theory (pp.113-144) in a canonical formulation that distinguishes itself from all makeshift theories. On neutral equilibrium of phase transition: 1. No restoring force so that a small forcing can drive a large change, such as the ice age. 2,The temperature is always constant, the origin of thermostat, the basis of no global warming. Then why is the earth not at 100oC? New Idea. Cloud is the fourth phase of water, lowering the ``boiling point" to the dew point of the cloud (pp.145-179). What if the cloud covers the whole sky, then the dreaded global warming will commence in earnest? But this will happen 2000 years later yet the fossil fuels will be gone in 300 years. Phase transition is a chemical equilibrium, not in the general circulation model , which cannot solve climate problems with super-computer.

    ANCA vasculitis encompasses several autoimmune conditions characterised by destruction of small vessels, inflammation of the respiratory tract and glomerulonephritis. Most patients harbour autoantibodies to myeloperoxidase (MPO) or proteinase 3 (PR3). Clinical and experimental data suggest that pathogenesis is driven by ANCA-mediated activation of neutrophils and monocytes. We investigated a potential role for distinct monocyte subsets. We found that the relative proportion of intermediate monocytes is increased in patients versus control individuals, and both MPO and PR3 are preferentially expressed on these cells. We demonstrate that MPO and PR3 are expressed independently of each other on monocytes and that PR3 is not associated with CD177. MPO expression correlates with that of Fc receptor CD16 on intermediate monocytes. Monocyte subsets respond differently to antibodies directed against MPO and PR3, with anti-MPO but not anti-PR3 leading to increased IL-1β, IL-6 and IL-8 production. In concordance with the observed higher surface expression of MPO on intermediate monocytes, this subset produces the highest quantity of IL-1β in response to anti-MPO stimulation. These data suggest that monocytes, specifically, the intermediate subset, may play a role in ANCA vasculitis, and also indicate that substantial differences exist between the effect of anti-MPO and anti-PR3 antibodies on these cells.

  17. Study on the factors that influence the intention of college students to participate in the green building

    Full Text Available The concept of green building has been extended for a period of time on both sides of the Taiwan Strait. However, there still is curiosity and skepticism in Fujian on green building. While in Taiwan, villages are filled with green-evolved houses and modern environmental farmhouses. With Theory of Planned Behavior as the framework, this study investigates influences of college students’ attitude toward green building, subjective norms of green building and perceived behavioral control of green building on the intention to participate in the green building. Findings show that college students’ attitude toward green building and the perceived behavioral control of green building significantly influence the intention to participate in the green building, but “subjective norms of green building” doesn’t have significant influence. The reason is probably that college students are at the rebellious stage and have high self consciousness and independent viewpoints.

    The University of Texas at Austin and The Technical University of Munich 2015 Solar Decathlon house is called Nexushaus because it combines UT Austin and TUM students in an affordable modular residential green building in the context of Austin, Texas, based on shape forming principles found in nature that demonstrates transformative technologies in Zero Net Energy, Zero Net Water and Carbon Neutrality. To meet the needs of the competition, a portable modular design has been developed with an assembly that enables ease of installation and both quantitative and qualitative performance in the design. The prefabricated house sits lightly on the land and forms the superstructure for photovoltaic technologies, rainwater collection, aquaculture and permaculture gardening and indoor/outdoor living. The ultimate goal of Nexushaus is to serve as a potential prototype for a next-generation modular home that could be reproduced in mass in an assembly plant in Austin.

    Object: To safely and securely store radioactive rare gases for a long period of time. Structure: The waste gases produced in nuclear power plant are cooled by a cooler and then introduced into a low temperature adsorbing device so that the gases are adsorbed by adsorbents, and then discharged into atmosphere through the purifying gas discharge line. When the radioactive rare gases reach a level of saturation in the amount of adsorption, they are heated and extracted by a suction pump and heated by a heater. The gases are then introduced into an oxygen-impurity removing device and the purified rare gases containing no oxygen and impurities are cooled by a cooler and fed into a gas holder. When the amount of radioactive rare gases stored within the gas holder reaches a given level, they are compressed and sealed by a compressure into a storing cylinder and residual gases in the piping are sucked and recovered into the gas holder, after which the cylinder is removed and stored in a fixed room.

    2017-11-01

    A very limited number of green and sustainable construction studies have explored factors related to Urban Heat Island (UHI) in tropical middle-class housing. This paper aimed to investigate the correlation of Urban Heat Island in tropical middle-class housing in three urban housing for middle-class residents of Palembang, which were Taman Sari Kenten, TOP Jakabaring, and Talang Kelapa. Samples consisted of 125 Taman Sari Kenten housing, 27 Talang Kelapa housing, and 12 TOP Jakabaring housing. Independent variables were the resident density, socioeconomic status, house location, roof type, green area ratio, weather, time, air conditioner, pro-environment institution, and NEP scale. The Analytic method included correlation and regression. We identified that all housing had different UHI profiles where Taman Sari Kenten had the highest UHI (4.17 K), followed by Talang Kelapa (2.66 K) and TOP Jakabaring (0.66 K) against temperature in measuring station nearby, owned by BMKG (National Meteorological Station). UHI correlated with the resident density, roof type, green area ratio, weather, time, and air conditioner. The results should add to the design of ideal housing in the tropical climate for middle-class residents, focusing on its ability to mitigate Urban Heat Island.

    2001-01-01

    This paper analyzes the economic and environmental impact of a policy instrument that is related to the tax deductibility of interest returns and dividend yields from specified 'green' projects. We investigate this so-called 'Green Project Facility' (Regeling Groenprojecten) in the Netherlands during 1995-1999. We analyze the effect on tax income, economic growth, employment, as well as on the emission of a number of gases and on solid waste production. We find that the economic effects in general are positive. This policy instrument increases growth, employment, and net tax income. However, the environmental effects are quite mixed. This especially results from the fact that a lot of projects would have been undertaken anyhow. Furthermore, we find that this green fiscal policy instrument is skewed towards energy and building. It appears to neglect environmental problems with consumer households, industry, and transport. 8 refs

  9. Evolution of Greenery in Housing Estates

    Kłopotowski, Maciej

    2017-10-01

    One of the basic values of multi-family housing estates which were built in the second half of the 20th century was their green areas. It was assumed that open spaces would serve both recreational and health purposes (related to air ventilation or air purification). In Poland, as in other socialist countries, these areas were parameterized and their size was defined in the relevant legislative documents. The principles of location of these sites in the structure of the estate as well as their equipment have changed during the period taken under consideration. Comparative analysis of specific realizations allows for their characterization and evaluation and reference to contemporary views. In the 1940s and 1950s, these areas were designed in the form of small squares and green areas located in the neighbourhood of the streets. In the sixties and seventies there were small residential parks (usually less than 1 ha). In the 1980s, extensive green areas were being developed which, for economic reasons, remained untouched in a functional way. Another decade (1990s) is associated with political and economic changes in Poland. In the case of estate greenery, it resulted in a complete deviation from its implementation. However, green was introduced on the roofs of buildings (including underground garages). Nowadays, the return to the design of large areas of greenery connected with housing development is being re-established. Their main function is recreational and leisure. One of the new tasks assigned to them is the task of gathering precipitation water. As a result of the analyses conducted, the author indicates which of the historical realizations (chosen periods) best meet modern needs and which can be adapted.

  10. Method of contacting solids and gases

    A continuous method is described for contacting solids and gases. The process involves passing a confined stream of gases through an extended path including a treating zone and imposing a pressure on the stream of gases at least sufficient to overcome the resistence of said path to the flow of said gases. A solid in finely divided form is then introduced into said stream of gases, maintaining a vertical column of finely divided solid in fluidized state of a height which will produce a pressure at the column bottom at least equal to the gas pressure at the point of entry of the solids into the stream. The solids then pass from the bottom of the column into the stream.

    The depletion of world fossil fuel reserves and the involvement of greenhouse gases in the global warming has led to change the industrial and energy policies of most developed countries. The goal is now to reserve petroleum to the uses where it cannot be substituted, to implement renewable raw materials obtained from plants cultivation, and to consider the biodegradability of molecules and of manufactured objects by integrating the lifetime concept in their expected cycle of use. The green chemistry includes the design, development and elaboration of chemical products and processes with the aim of reducing or eliminating the use and generation of harmful compounds for the health and the environment, by adapting the present day operation modes of the chemical industry to the larger framework of the sustainable development. In addition to biofuels, this book reviews the applications of green chemistry in the different industrial processes in concern. Part 1 presents the diversity of the molecules coming from renewable carbon, in particular lignocellulose and the biotechnological processes. Part 2 is devoted to materials and treats of the overall available technological solutions. Part 3 focusses on functional molecules and chemical intermediates, in particular in sugar- and fats-chemistry. Part 4 treats of biofuels under the aspects of their production and use in today's technologies. The last part deals with the global approaches at the environmental and agricultural levels. (J.S.)

    Full Text Available The article gives an overview of key aspect of housing in Municipality of Ljubljana. The characteristics of households, of housing and their relation influence the housing situation in the city. Characteristic of housing refer mainly to quality of the dwellings, affordability and correspondence to the wishes of the inhabitants. The second important dimensions are households and their characteristics. In Europe and Slovenia increase in number of household can be observed, which in turn are becoming smaller. The housing policy has a role in establishing a balance between households and housing, i.e. ensuring that housing corresponds to the needs of individual households and to their number. For achieving this, knowledge and appropriate data are of vital importance. In the article we present the results of the Housing survey 2005. We observe housing conditions in a comparative perspective (Ljubljana in comparison to Maribor, Slovenia and selected European cities and according to three dimensions: housing fund, households and housing conditions.

    Granular gases are composed of macroscopic bodies kept in motion by an external energy source such as a violent shaking. The behaviour of such systems is quantitatively different from that of ordinary molecular gases: due to the size of the constituents, external fields have a stronger effect on the dynamics and, more importantly, the kinetic energy of the gas is no longer a conserved quantity. The key role of the inelasticity of collisions has been correctly appreciated for about fifteen years, and the ensuing consequences in terms of phase behaviour or transport properties studied in an increasing and now vast body of literature. The purpose of this book is to help the newcomer to the field in acquiring the essential theoretical tools together with some numerical techniques. As emphasized by the authors-who were among the pioneers in the domain- the content could be covered in a one semester course for advanced undergraduates, or it could be incorporated in a more general course dealing with the statistical mechanics of dissipative systems. The book is self-contained, clear, and avoids mathematical complications. In order to elucidate the main physical ideas, heuristic points of views are sometimes preferred to a more rigorous route that would lead to a longer discussion. The 28 chapters are short; they offer exercises and worked examples, solved at the end of the book. Each part is supplemented with a relevant foreword and a useful summary including take-home messages. The editorial work is of good quality, with very few typographical errors.

    Since 1850, that is to say the beginning of the industrial era,the concentration of carbon dioxide in the atmosphere has risen from 280 ppm to 370 ppm, this increase is mainly due to the combustion of fossil fuels. Today fossil fuels represent 85% of all the energy used in the world. Fearing progressive climatic changes, more and more governments become aware of the necessity of reducing the emission of greenhouse gases. A more efficient use of energy and the promoting of renewable energies and of the nuclear energy are the most evident solutions but they appear to be insufficient. A third solution is the storage of carbon dioxide in geological layers. This technique has been put into use since 1996 in Norway. An off-shore natural gas platform injects carbon dioxide in a geological reservoir situated 1000 meters below the ocean bed. The injection of CO 2 could be used in oil fields in order to facilitate the extraction of petroleum. Far more large and efficient reservoirs would be the oceans, they already hold up 40000 10 9 tons of dissolved CO 2 . Even if the double of the carbon dioxide accumulated in the atmosphere since 1850 were injected, the concentration of carbon in sea waters would rise by less than 2%. The safety of CO 2 storage and the impact on the environment of ocean injection sites are being studied. (A.C.)

    Global cooperation is essential in cutting greenhouse-gas emissions, say Alice LeBlanc and Daniel J. Dudek of the Environmental Defense in New York City. The first step, they continue, is agreement among nations on an overall global limit for all greenhouse gases, followed by an allocation of the global limit among nations. The agreements must contain effective reporting and monitoring systems and enforcement provisions, they add. The Framework Convention on Climate Change, signed by most nations of the world in Brazil in 1992, provides the foundation for such an agreement, LeBlanc and Dudek note. open-quotes International emissions trading is a way to lower costs and expand reduction options for the benefit of all,close quotes they contend. Under such an arrangement, an international agency would assign allowances, stated in tons of carbon dioxide. Countries would be free to buy and sell allowances, but no country could exceed, in a given year, the total allowances it holds. By emitting less than its allowed amount, a country would accumulate more allowances, which it could sell. The authors claim such a system would offer benefits to the world economy by saving billions of dollars in pollution-reduction costs while still achieving emission limits established in an international agreement

    The Eco House is a former park keeper's lodge on the periphery of Leicester's largest public park. Taken over by Leicester Ecology Trust in 1990, the Eco House was a successor to the Trust's earlier low energy house. This has been a local authority decant house, retrofitted to show the potential for increased energy efficiency in older buildings. Many of the ideas from the earlier project were adopted by the new with a widening of its remit to include all matters of environmental concern connected with people's homes. So in addition to energy efficiency, other issues addressed include conservation of resources, wildlife, organic gardening, food production, water, environmental consumerism, recycling and health. Given that the use of energy is regarded by many environmentalists to be the single most important environmental issue today, and one which is easiest for households to address, it remains the project's dominant theme.

    Laboratory animal procedures using gas anesthetics may amass elevated waste gas concentrations in operating rooms if controls are not implemented for capturing and removing the vapors. Area sampling using an infrared analyzer indicated isoflurane concentrations likely to exceed occupational exposure guidelines. Our study showed environmental concentrations of oxygen as high as 40% and isoflurane concentrations >100 ppm when no controls or merely passive controls were utilized. These extraneous isoflurane emissions were determined to be originating from the pre-procedural induction process as well as the gas delivery nose cone. A novel waste gas collection cylinder was designed to enclose the gas delivery nose cone and animal head during the administration of anesthetic gases. The vented cylinder utilized a house vacuum to remove the waste anesthetic gases from the surgical field. A commercially available induction chamber designed to be actively and externally exhausted was used to lower concentrations during the induction process. With implementation of local exhaust ventilation controls, waste anesthetic gas concentrations decreased to below recommended occupational exposure levels. In vitro (sham) testing compared favorably to in vivo measurements validating the reduction capability of active ventilation during rodent anesthetic administration. In vivo isoflurane reductions for the induction chamber emissions, the operating room, and the surgeon's breathing zone were 95%, 60%, and 53%, respectively. The same measurements for an in vitro procedure were 98%, 84%, and 87%, respectively.

  12. Passive houses in Norway

    Energy Technology Data Exchange (ETDEWEB)

    2008-12-15

    The paper analyzes the introduction of passive houses in the Norwegian house market. Passive houses are houses with extremely low levels of energy consumption for heating, and have not yet been built in Norway, but have started to enter the market in Germany and some other countries. The construction sector is analyzed as a sectoral innovation system. The different elements of the innovation system are studied. This includes government agencies, producers, consumers, finance and education. The analysis shows that passive and low-energy houses are on the verge of market breakthrough. This can partly be explained by economic calculations, and partly by processes of learning and change in the institutional set-up of the sector. The construction sector is a sector characterized by low innovative intensity and little interaction between different agents. Those working to promote passive houses have to some extent managed to cope with these challenges. This has happened by breaking away from the traditional focus of Norwegian energy efficiency policies on technology and the economically rational agents, by instead focusing on knowledge and institutional change at the level of the producers.

    The connection between housing and health is well established. Physical, chemical, and biological aspects of the child's home, such as cleanliness, moisture, pests, noise, accessibility, injury risks, and other forms of housing environmental quality, all have the potential to influence multiple aspects of the health and development of children. Basic sanitation, reduced household crowding, other improvements in housing and expanded, and improved housing regulations have led to advances in children's health. For example, lead poisoning prevention policies have profoundly reduced childhood lead exposure in the United States. This and many other successes highlight the health benefits for families, particularly children, by targeting interventions that reduce or eliminate harmful exposures in the home. Additionally, parental mental health problems, food insecurity, domestic violence, and the presence of guns in children's homes all are largely experienced by children in their homes, which are not as yet considered part of the Healthy Homes agenda. There is a large movement and now a regulatory structure being put in place for healthy housing, which is becoming closely wedded with environmental health, public health, and the practice of pediatrics. The importance of homes in children's lives, history of healthy homes, asthma, and exposures to lead, carbon monoxide, secondhand/thirdhand smoke, radon, allergy triggers is discussed, as well as how changes in ambient temperature, increased humidity, poor ventilation, water quality, infectious diseases, housing structure, guns, electronic media, family structure, and domestic violence all affect children's health.

    The positive relationships between urban green space and health have been well documented. Little is known, however, about the role of residents' emotional attachment to local green spaces in these relationships, and how attachment to green spaces and health may be promoted by the availability of accessible and usable green spaces. The present research aimed to examine the links between self-reported health, attachment to green space, and the availability of accessible and usable green spaces. Data were collected via paper-mailed surveys in two neighborhoods (n = 223) of a medium-sized Dutch city in the Netherlands. These neighborhoods differ in the perceived and objectively measured accessibility and usability of green spaces, but are matched in the physically available amount of urban green space, as well as in demographic and socio-economic status, and housing conditions. Four dimensions of green space attachment were identified through confirmatory factor analysis: place dependence, affective attachment, place identity and social bonding. The results show greater attachment to local green space and better self-reported mental health in the neighborhood with higher availability of accessible and usable green spaces. The two neighborhoods did not differ, however, in physical and general health. Structural Equation Modelling confirmed the neighborhood differences in green space attachment and mental health, and also revealed a positive path from green space attachment to mental health. These findings convey the message that we should make green places, instead of green spaces.

    The Amazon plays an important role on the global carbon cycle, as changing as carbon storage, since Amazon Basin is the biggest area of tropical forest, around 50% of global. Natural's process, deforestation, and use land are CO 2 sources. The Amazon forest is a significant source of N 2 O by soil process, and CH 4 by anaerobic process like flooded areas, rice cultures, and others sources. This project is part of the LBA project (Large-Scale Biosphere Atmosphere Experiment in Amazonia), and this project is 'Vertical profiles of carbon dioxide and other trace gas species over the Amazon basin using small aircraft'. Since December 2000 vertical profiles of CO 2 , CH 4 , CO, H 2 , N 2 O and SF 6 have been measured above central Amazonia. The local sampling was over Tapajos National Forest, a primary forest in Para State, where had a CO 2 flux tower and an east impact area with sources like animals, rice cultivation, biomass burning, etc, to compare the influence of an impact area and a preserved area in the profiles. The Reserva Biologica de Cuieiras, at Amazon State, is the other studied place, where there already exists a CO 2 flux tower, and an east preserved area at this State, to compare with the Cuieiras. The sampling has been carried out on vertical profile from 1000 ft up to 12000 ft using a semi-automated sampling package developed at GMD/NOAA and a small aircraft. The analysis uses the MAGICC system (Multiple Analysis of Gases Influence Climate Change) which is installed at the Atmospheric Chemistry Laboratory (LQA) in IPEN (Instituto de Pesquisas Energeticas e Nucleares). The results showed that all gases studied, except H 2 gas, has been following the global trend. At the Para State, for the studied years, the Amazonian Forest performed as small CO 2 sink. To compare Wet and Dry Seasons, subtracted the Ascension concentration values in the period to remove the global influence. So that, in the 2004 and 2005 wet seasons and 2004 dry season comparison it was

  7. Dipolar quantum gases of erbium

    International Nuclear Information System (INIS)

    Frisch, A.

    2014-01-01

    Since the preparation of the first Bose-Einstein condensate about two decades ago and the first degenerate Fermi gas following four years later a plethora of fascinating quantum phenomena have been explored. The vast majority of experiments focused on quantum degenerate atomic gases with short-range contact interaction between particles. Atomic species with large magnetic dipole moments, such as chromium, dysprosium, and erbium, offer unique possibilities to investigate phenomena arising from dipolar interaction. This kind of interaction is not only long-range but also anisotropic in character and imprints qualitatively novel features on the system. Prominent examples are the d-wave collapse of a dipolar Bose-Einstein condensate of chromium atoms realized by the group in Stuttgart, the spin magnetization and demagnetization dynamics observed by groups in Stuttgart, Paris, and Stanford, and the deformation of the Fermi surface observed by our group in Innsbruck. This thesis reports on the creation and study of the first Bose-Einstein condensate and degenerate Fermi gas of erbium atoms. Erbium belongs to the lanthanide group of elements and has a large magnetic moment of seven Bohr magneton. In particular, this thesis describes the experimental apparatus and the sequence for producing a dipolar quantum gas. There is an emphasis on the production of the narrow-line magneto-optical trap of erbium since this represents a very efficient and robust laser-cooling scheme that greatly simplifies the experimental procedure. After describing the experimental setup this thesis focuses on several fundamental questions related to the dipolar character of erbium and to its lanthanide nature. A first set of studies centers on the scattering properties of ultracold erbium atoms, including the elastic and the inelastic cross section and the spectrum of Feshbach resonances. Specifically, we observe that identical dipolar fermions do collide and rethermalize even at low temperatures

It is based on the measurement of the local pressure inside a trapped gas from the analysis of its in situ image. We first apply this method to the study of a Fermi gas with resonant interactions, a weakly-interacting 7 Li gas acting as a thermometer. Surprisingly, none of the existing many-body theories of the unitary gas accounts for the equation of state deduced from our study over its full range. The virial expansion extracted from the high-temperature data agrees with the resolution of the three-body problem. At low temperature, we observe, contrary to some previous studies, that the normal phase behaves as a Fermi liquid. Finally we obtain the critical temperature for superfluidity from a clear signature on the equation of state. We also measure the pressure of the ground state as a function of spin imbalance and interaction strength - measure directly relevant to describe the crust of neutron stars. Our data validate Monte-Carlo simulations and quantify the Lee-Huang-Yang corrections to mean-field interactions in low-density fermionic or bosonic superfluids. We show that, in most cases, the partially polarized normal phase can be described as a Fermi liquid of polarons. The polaron effective mass extracted from the equation of state is in agreement with a study of collective modes. (author)

  9. Rare gases in Samoan xenoliths

    The rare gas isotopic compositions of residual harzburgite xenoliths from Savai'i (SAV locality) and an unnamed seamount south of the Samoan chain (PPT locality) provide important constraints on the rare gas evolution of the mantle and atmosphere. Despite heterogeneous trace element compositions, the rare gas characteristics of the xenoliths from each of the two localities are strikingly similar. SAV and PPT xenoliths have 3He/ 4He ratios of11.1 ± 0.5 R A and21.6 ± 1 R A, respectively; this range is comparable to the 3He/ 4He ratios in Samoan lavas and clearly demonstrates that they have trapped gases from a relatively undegassed reservoir. The neon results are not consistent with mixing between MORB and a plume source with an atmospheric signature. Rather, the neon isotopes reflect either a variably degassed mantle (with a relative order of degassing of Loihi Honda et al. that the 20Ne/ 22Ne ratio in the mantle more closely resembles the solar ratio than the atmospheric one. 40Ar/ 36Ar ratios in the least contaminated samples range from 4,000 to 12,000 with the highest values in the 22 RA PPT xenoliths. There is no evidence for atmospheric 40Ar/ 36Ar ratios in the mantle source of these samples, which indicates that the lower mantle may have 40Ar/ 36Ar ratios in excess of 5,000. Xenon isotopic anomalies in 129Xe and 136Xe are as high as 6%, or about half of the maximum MORB excess and are consistent with the less degassed nature of the Samoan mantle source. These results contradict previous suggestions that the high 3He/ 4He mantle has a near-atmospheric heavy rare gas isotopic composition.

    This study explores factors contributing to delays and relocations during the implementation of the Housing First model in Toronto, Ontario. While interruptions in housing tenure are expected en route to recovery and housing stability, consumer and service provider views on finding and keeping housing remain largely unknown. In-person interviews and focus groups were conducted with 48 study participants, including 23 case managers or housing workers and 25 consumers. The following three factors contributed to housing delays and transfers: (1) the effectiveness of communication and collaboration among consumers and service providers, (2) consumer-driven preferences and ambivalence, and (3) provider prioritization of consumer choice over immediate housing access. Two strategies--targeted communications and consumer engagement in housing searches--supported the housing process. Several factors affect the timing and stability of housing. Communication between and among providers and consumers, and a shared understanding of consumer choice, can further support choice and recovery.

  11. Constructing passive houses

    Everybody can learn to build energy-efficient. It needs theoretical and practical experience. 1997 we built the first freestanding Passive House in Europe, the Passive House Oehler. There had been a lot of questions, starting with the insecurity, whether the calculation program of the Passive House Institute, the PHPP, is working properly in our case. Nobody knew at that time because nobody tried it out before. It took us a lot of time to find out and every detail of the construction hat to be invented to meet the very high demand of thermal quality. All the following houses needed less time and had fewer open questions, adding one piece of experience with every building. 2002 we realised the biggest Passive House, the office building Energon Ulm with 420 working spaces. In the meantime we have learned a lot like how to produce prefabricated timber elements for the facades, providing good insulation, air tightness and avoiding serious thermal bridges. We have proofed, that any kind of building type can be a Passive House. And with increasing experience the freedom of design and construction is growing. Even the economical efficiency increased. The Energon Ulm is providing a much better indoor climate than any other office building and was build 10 % cheaper than an average German office building. At present the Passive House Standard is the most efficient solution for the user to live in the desired comfort zone between 20 C and 25 C. This zone of individual feeling-well can be described with the term ''operative temperature''. This term is defined by factors like air temperature, radiation temperature of warm and cold surfaces, air speed and humidity. The result of all these factors has to be within 18 C to 25 C without accepting one of the factors getting extreme.

    PEP stands for 'Promotion of European Passive Houses' and is a consortium of European partners, supported by the European Commission, Directorate General for Energy and Transport. In this working paper an overview is given of Passive House solutions. An inventory has been made of Passive House solutions for new build residences applied in each country. Based on this, the most common basic solutions have been identified and described in further detail, including the extent to which solutions are applied in common and best practice and expected barriers for the implementation in each country. An inventory per country is included in the appendix. The analysis of Passive House solutions in partner countries shows high priority with regard to the performance of the thermal envelope, such as high insulation of walls, roofs, floors and windows/ doors, thermal bridge-free construction and air tightness. Due to the required air tightness, special attention must be paid to indoor air quality through proper ventilation. Finally, efficient ((semi-)solar) heating systems for combined space and DHW heating still require a significant amount of attention in most partner countries. Other basic Passive House solutions show a smaller discrepancy with common practice and fewer barriers have been encountered in partner countries. In the next section, the general barriers in partner countries have been inventoried. For each type of barrier a suggested approach has been given. Most frequently encountered barriers in partner countries are: limited know-how; limited contractor skills; and acceptation of Passive Houses in the market. Based on the suggested approaches to overcoming barriers, this means that a great deal of attention must be paid to providing practical information and solutions to building professionals, providing practical training to installers and contractors and communication about the Passive House concept to the market.

    This present time, Indonesia just began applying the concept of Green Architecture. The actions require community participation as residents and the users of the building. The built environment is designed around the idea of Green Architecture but inhabited and managed improperly; the goal of sustainable built environment is not achieved. The aspect of behaviour is the key factor in the implementation of Green Architecture’s concept. This research is a descriptive exploratory which is to identify the problems to the implementation of Green Architecture’s concept in planned housing. Then the study will explore the components causes of the problems used as a problem solver. The study conducted on the living behaviour in Citraland Bagya City’s resident. The estate is designed and built with the concept of Green Architecture in Medan city. The research was carried out by the four aspects of housing are the physical, social and cultural, policy, and management issue. These three components will indirectly relate to the economic issues that are the efficiency and effectiveness of living behaviour. The results showed that the increasing of green behavior is still small and the occupant requires motivation and socialization of living green.

    This report looks at discussions on a green economy and green jobs in international organizations such as the OECD, EU and UNEP. It also studies the structural change in the green economy in Finland and how this change will be brought forward by the year 2050 through low carbon technology and innovations. It draws special attention to how citizens' perception of risks and their development impact the approval and acceptance of climate policies and measures. Finland will continue to be a country that utilises natural resources, and where a large part of its industrial sector will be energy- and material-intensive forest, mining and basic metal industries. The following factors will have an impact on work: Energy production is mainly based on renewable energy sources such as bio-, wind and solar power. Energy and material efficiency are important targets; emissions will decrease also in work places. Repairs and wood-based building will increase; new houses will produce energy. Reuse will increase; former waste disposal sites will function as mines. Organic and GMO foodstuffs will become popular. Electric and hybrid cars will take over the markets. Environmental applications of gene- and nanotechnology will become widely used. Physical workplaces and strictly controlled working times will lose their importance; virtual offices and remote work become popular. Products will be produced to last, with renewable usage in mind, and repair and maintenance of products will become more common. Occupational health and safety issues are of paramount importance especially in bio-energy production, repair and maintenance work, as well as waste management. Especially nano- and biotechnology and hazardous chemicals require careful risk management; the precautionary principle is applied to them. Studies on a green economy and green jobs usually look very positively at the possibilities of creating new jobs through environmental policies. Employment estimates done in the past may

    1999-01-01

    The dissipative nature of the particle interactions in granular systems renders granular gases mesoscopic and bearing some similarities to regular gases in the ''continuum transition regime'' where shear rates and/or thermal gradients are very large). The following properties of granular gases support the above claim: (i). Mean free times are of the same order as macroscopic time scales (inverse shear rates); (ii). Mean free paths can be macroscopic and comparable to the system's dimensions; (iii). Typical flows are supersonic; (iv). Shear rates are typically ''large''; (v). Stress fields are scale (resolution) dependent; (vi). Burnett and super-Burnett corrections to both the constitutive relations and the boundary conditions are of importance; (vii). Single particle distribution functions can be far from Gaussian. It is concluded that while hydrodynamic descriptions of granular gases are relevant, they are probing the boundaries of applicability of hydrodynamics and perhaps slightly beyond

    1996-12-01

    Green thunderstorms have been observed from time to time in association with deep convection or severe weather events. Often the green coloration has been attributed to hail or to reflections of light from green foliage on the ground. Some skeptics who have not personally observed a green thunderstorm do not believe that green thunderstorms exist. They suggest that the green storms may be fabrications by excited observers. The authors have demonstrated the existence of green thunderstorms objectively using a spectrophotometer. During the spring and summer of 1995 the authors observed numerous storms and recorded hundreds of spectra of the light emanating corn these storms. It was found that the subjective judgment of colors can vary somewhat between observers, but the variation is usually in the shade of green. The authors recorded spectra of green and nongreen thunderstorms and recorded spectral measurements as a storm changed its appearance from dark blue to a bluish green. The change in color is gradual when observed from a stationary position. Also, as the light from a storm becomes greener, the luminance decreases. The authors also observed and recorded the spectrum of a thunderstorm during a period of several hours as they flew in an aircraft close to a supercell that appeared somewhat green. The authors' observations refute the ground reflection hypothesis and raise questions about explanations that require the presence of hail.

  17. Analysis of electron interactions in dielectric gases

    Olivet, Aurelio; Duque, Daniel; Vega, Lourdes F.

    2007-01-01

    We present and discuss results concerning electron interactions processes of dielectric gases and their relationship with the macroscopic behavior of these gases, in particular, with their dielectric strength. Such analysis is based on calculating energies of reactions for molecular ionization, dissociative ionization, parent negative ion formation, and dissociative electron attachment processes. We hypothesize that the estimation of the required energy for a reduced number of processes that take place in electrically stressed gases could be related to the gas' capability to manage the electron flow during an electrical discharge. All calculations were done with semiempirical quantum chemistry methods, including an initial optimization of molecular geometry and heat of formation of the dielectric gases and all of species that appear during electron interaction reactions. The performance of semiempirical methods Austin model 1 and Parametric model 3 (PM3) was compared for several compounds, PM3 being superior in most cases. Calculations performed for a sample of nine dielectric gases show that electron attachment and detachment processes occur in different energy bands that do not overlap for any value of the dielectric strength. We have also analyzed the relationship between dielectric strength and two physical properties: electron affinity and ionization energy. Calculations performed for 43 dielectric gases show no clear correlation between them, although certain guidelines for the qualitative estimation of dielectric strength can still be assessed

    2013-08-01

    Working with builder partners on a test homes allows for vetting of whole-house building strategies to eliminate any potential unintended consequences prior to implementing these solution packages on a production scale. To support this research, CARB partnered with Preferred Builders Inc. on a high-performance test home in Old Greenwich, CT. The philosophy and science behind the 2,700 ft2 'Performance House' was based on the premise that homes should be safe, healthy, comfortable, durable, efficient, and adapt with the homeowners. The technologies and strategies used in the 'Performance House' were not cutting-edge, but simply 'best practices practiced'. The focus was on simplicity in construction, maintenance, and operation. When seeking a 30% source energy savings targets over a comparable 2009 IECC code-built home in the cold climate zone, nearly all components of a home must be optimized. Careful planning and design are critical. To help builders and architects seeking to match the performance of this home, a step-by-step guide through the building shell components of DOE's Challenge Home are provided in a pictorial story book. The end result was a DOE Challenge Home that achieved a HERS Index Score of 20 (43 without PV, the minimum target was 55 for compliance). This home was also awarded the 2012 HOBI for Best Green Energy Efficient Home from the Home Builders & Remodelers Association of Connecticut.

  3. GREEN MANAGEMENT: THE REALITY OF BEING GREEN IN BUSINESS

    OpenAIRE

    Tran, Ben

    2009-01-01

    Green management and going green are not as clear cut and easy as hyped by the general media. While going ecologically green is indeed beneficial and appropriate, the process and procedure of becoming green is anything but easy. Firstly, turning green is largely not a legal requirement, but a voluntary process. Thus, even though LEED (which is by far the more publicly known green certification standard) governs the certification of the green management effort, it is not a compulsory condition...

    2014-01-01

    The Hood River Passive Project was developed by Root Design Build of Hood River Oregon using the Passive House Planning Package (PHPP) to meet all of the requirements for certification under the European Passive House standards. The Passive House design approach has been gaining momentum among residential designers for custom homes and BEopt modeling indicates that these designs may actually exceed the goal of the U.S. Department of Energy's (DOE) Building America program to "reduce home energy use by 30%-50% (compared to 2009 energy codes for new homes). This report documents the short term test results of the Shift House and compares the results of PHPP and BEopt modeling of the project. The design includes high R-Value assemblies, extremely tight construction, high performance doors and windows, solar thermal DHW, heat recovery ventilation, moveable external shutters and a high performance ductless mini-split heat pump. Cost analysis indicates that many of the measures implemented in this project did not meet the BA standard for cost neutrality. The ductless mini-split heat pump, lighting and advanced air leakage control were the most cost effective measures. The future challenge will be to value engineer the performance levels indicated here in modeling using production based practices at a significantly lower cost.

    Sales of green power products are booming in Europe: 50,000 customers in the United Kingdom, 775,000 in the Netherlands and 300,000 in Germany. Laws of physics are however formal: the way in which electricity flows within the grid does not allow suppliers to assure customers that they are directly receiving electricity produced exclusively from renewable energy sources. What are marketers selling their customers then? Laetitia Ouillet, Greenprices, takes a closer look and focuses on the potential of selling green energy in the forms of renewable energy certificates.

    2013-11-01

    After having recalled the definition and origin of shale gases, the different non conventional gases and their exploitation techniques (hydraulic fracturing and horizontal drilling) this report examines whether these gases are an opportunity for France. Some characteristics and data of the fossil and gas markets are presented and commented: world primary energy consumption, proved reserves of non conventional gases and their locations, European regions which may possess reserves of shale gases and coal-bed methane, origins of gas imports in France. The second part addresses shale gas deposits and their exploitation: discussion of the influence of the various rock parameters, evolution of production. The third part discusses the exploitation techniques and specific drilling tools. The issue of exploitation safety and security is addressed as well as the associated controversies: about the pollution of underground waters, about the fact that deep drillings result in pollution, about the risks associated with hydraulic fracturing and injections of chemical products, about the hold on ground and site degradation, about water consumption, about pollution due to gas pipeline leakage, about seismic risk, about noise drawbacks, about risks for health, about exploration and production authorization and license, and about air pollution and climate. The last part addresses the French situation and its future: status of the energy bill, recommendations made by a previous government, cancellation of authorizations, etc. Other information are provided in appendix about non conventional hydrocarbons, about shale gas exploitation in the USA, and about the Lacq gas

  1. Retrofitted green roofs and walls and improvements in thermal comfort

    Science.gov (United States)

    Feitosa, Renato Castiglia; Wilkinson, Sara

    2017-06-01

    Increased urbanization has led to a worsening in the quality of life for many people living in large cities in respect of the urban heat island effect and increases of indoor temperatures in housing and other buildings. A solution may be to retrofit existing environments to their former conditions, with a combination of green infrastructures applied to existing walls and rooftops. Retrofitted green roofs may attenuate housing temperature. However, with tall buildings, facade areas are much larger compared to rooftop areas, the role of green walls in mitigating extreme temperatures is more pronounced. Thus, the combination of green roofs and green walls is expected to promote a better thermal performance in the building envelope. For this purpose, a modular vegetated system is adopted for covering both walls and rooftops. Rather than temperature itself, the heat index, which comprises the combined effect of temperature and relative humidity is used in the evaluation of thermal comfort in small scale experiments performed in Sydney - Australia, where identical timber framed structures prototypes (vegetated and non-vegetated) are compared. The results have shown a different understanding of thermal comfort improvement regarding heat index rather than temperature itself. The combination of green roof and walls has a valid role to play in heat index attenuation.

    President Clinton has directed the White House office on Environmental Policy to coordinate an interagency process to develop a plan to fulfill the commitment he made in his Earth Day address on April 21, 1993. This plan will become the cornerstone of the Climate Change Plan that will be completed shortly after the Rio Accord enters into force. The Office on Environmental Policy established the Interagency Climate Change Mitigation Group to draw on the expertise of federal agencies including the National Economic Council; the Council of Economic Advisors; the Office of Science and Technology Policy; the Office of Management and Budget; the National Security Council; the Domestic Policy Council; the Environmental Protection Agency; and the Departments of Energy, Transportation, Agriculture, Interior, Treasury, Commerce, and State. Working groups have been established to examine six key policy areas: energy demand, energy supply, joint implementation, methane and other gases, sinks, and transportation. The purpose of the White House Conference on Global Climate Change was to ``tap the real-world experiences`` of diverse participants and seek ideas and information for meeting the President`s goals. During the opening session, senior administration officials defined the challenge ahead and encouraged open and frank conversation about the best possible ways to meet it.

    International Nuclear Information System (INIS)

    Anglin, J. R.; Ketterle, W.

    2003-01-01

    The early experiments on Bose-Einstein condensation in dilute atomic gases accomplished three longstanding goals. First, cooling of neutral atoms into their motional state, thus subjecting them to ultimate control, limited only by Heisenberg uncertainty relation. Second, creation of a coherent sample of atoms, in which all occupy the same quantum states, and the realization of atom lasers - devices that output coherent matter waves. And third, creation of gaseous quantum fluid, with properties that are different from the quantum liquids helium-3 and helium-4. The field of Bose-Einstein condensation of atomic gases has continued to progress rapidly, driven by the combination of new experimental techniques and theoretical advances. The family of quantum degenerate gases has grown, and now includes metastable and fermionic atoms. condensates have become an ultralow-temperature laboratory for atom optics, collisional physics and many-body physics, encompassing phonons, superfluidity, quantized vortices, Josephson junctions and quantum phase transitions.

  15. Density Fluctuations in Uniform Quantum Gases

    International Nuclear Information System (INIS)

    Bosse, J.; Pathak, K. N.; Singh, G. S.

    2011-01-01

    Analytical expressions are given for the static structure factor S(k) and the pair correlation function g(r) for uniform ideal Bose-Einstein and Fermi-Dirac gases for all temperatures. In the vicinity of Bose Einstein condensation (BEC) temperature, g(r) becomes long ranged and remains so in the condensed phase. In the dilute gas limit, g(r) of bosons and fermions do not coincide with Maxwell-Boltzmann gas but exhibit bunching and anti-bunching effect respectively. The width of these functions depends on the temperature and is scaled as √(inverse atomic mass). Our numerical results provide the precise quantitative values of suppression/increase (antibunching and bunching) of the density fluctuations at small distances in ideal quantum gases in qualitative agreement with the experimental observation for almost non-trapped dilute gases.

  16. Method of processing radioactive rare gase

    International Nuclear Information System (INIS)

    Tagusagawa, Atsushi; Tuda, Kazuaki.

    1988-01-01

    Purpose: To obtain a safety processing method without using mechanical pumps or pressure-proof containers and, accordingly, with no risk for the leakage of radioactive rare gas. Method: A container filled with zeolige is inserted with a cover being opened into an autoclave. Meanwhile, krypton-containing gases are supplied to an adsorption tower filled with adsorbents, cooled, adsorbed and then heated to desorb adsorbed krypton. The krypton-containing gases are introduced due to the pressure difference to the autoclave thereby causing krypton to adsorb at ambient temperature to zeolite. Then, the inside of the autoclave is heated to desorb krypton and adsorbed moistures from zeolite and the pressure is elevated. After sending the gases under pressure to the adsorption tower, the zeolite-filled container is taken out from the autoclave, tightly closed and then transferred to a predetermined site.

  17. GREENHOUSE GASES AND MEANS OF PREVENTION

    Directory of Open Access Journals (Sweden)

    Dušica Stojanović

    2013-09-01

    Full Text Available The greenhouse effect can be defined as the consequence of increased heating of the Earth's surface, as well as the lower atmosphere by carbon dioxide, water vapor, and other trace amounts gases. It is well-known that human industrial activities have released large amounts of greenhouse gases in the atmosphere, about 900 billion tons of carbon dioxide, and it is estimated that up to 450 billion are still in the atmosphere. In comparison to greenhouse gases water vapor is one of the greatest contributors to the greenhouse effect on Earth. Many projects, as does the PURGE project, have tendences to build on the already conducted research and to quantify the positive and negative impacts on health and wellbeing of the population with greenhouse gas reduction strategies that are curently being implemented and should be increasingly applied in various sectors and urban areas, having offices in Europe, China and India.

A Kadomtsev—Petviashvili I (KPI) solitary wave has been realized for superfluid Fermi gases in the limited cases of Bardeen—Cooper—Schrieffer (BCS) regime, Bose—Einstein condensate (BEC) regime, and unitarity regime. One-lump solution as well as one-line soliton solutions for the KPI equation are obtained, and two-line soliton solutions with the same amplitude are also studied in the limited cases. The dependence of the lump propagating velocity and the sound speed of two-dimensional superfluid Fermi gases on the interaction parameter are investigated for the limited cases of BEC and unitarity.

  20. The development of a green certificate market

    International Nuclear Information System (INIS)

    Morthost, P.E.

    2000-01-01

    Liberalizing the electricity industry and attempting to reduce the emissions of greenhouse gases are the two dominant trends in European energy policy. The last-mentioned issue might require the contribution from renewable energy technologies, but at present most renewables cannot compete on their own with conventional technologies. Thus, it can be expected that if renewables must compete solely on market conditions alone this will slow down or even halt the development of new renewable capacity. One model in which additional payments to renewable technologies are generated is based on the development of a separate green market. In Holland, a voluntary green certificate has existed since the beginning of 1998. In Denmark a comprehensive restructuring of the legislation for the electric power industry has just been completed, including the framework for developing a separate green market for renewable electricity production. The main objectives of introducing this type of electricity market in Denmark is to secure the development of renewable energy technologies (including contributions to greenhouse gas reductions), while at the same time releasing the Government from the (by now) quite heavy burden of subsidising renewable technologies. Finally, a green market will make it possible for these renewable technologies to be partly economically compensated for the environmental benefits, which they generate compared to conventional power production. With the recent Danish legislation as starting point this paper analyzes possible ways to set up a green certificate market, treating as well some of the consequences produced when the market is actually functioning. The analysis is applicable for all renewable technologies, but special attention is given to wind power. (author)

  5. Origins of geothermal gases at Yellowstone

    Science.gov (United States)

    Lowenstern, Jacob B.; Bergfeld, Deborah; Evans, William C.; Hunt, Andrew G.

    2015-01-01

    Gas emissions at the Yellowstone Plateau Volcanic Field (YPVF) reflect open-system mixing of gas species originating from diverse rock types, magmas, and crustal fluids, all combined in varying proportions at different thermal areas. Gases are not necessarily in chemical equilibrium with the waters through which they vent, especially in acid sulfate terrain where bubbles stream through stagnant acid water. Gases in adjacent thermal areas often can be differentiated by isotopic and gas ratios, and cannot be tied to one another solely by shallow processes such as boiling-induced fractionation of a parent liquid. Instead, they inherit unique gas ratios (e.g., CH4/He) from the dominant rock reservoirs where they originate, some of which underlie the Quaternary volcanic rocks. Steam/gas ratios (essentially H2O/CO2) of Yellowstone fumaroles correlate with Ar/He and N2/CO2, strongly suggesting that H2O/CO2 is controlled by addition of steam boiled from water rich in atmospheric gases. Moreover, H2O/CO2 varies systematically with geographic location, such that boiling is more enhanced in some areas than others. The δ13C and 3He/CO2 of gases reflect a dominant mantle origin for CO2 in Yellowstone gas. The mantle signature is most evident at Mud Volcano, which hosts gases with the lowest H2O/CO2, lowest CH4 concentrations and highest He isotope ratios (~16Ra), consistent with either a young subsurface intrusion or less input of crustal and meteoric gas than any other location at Yellowstone. Across the YPVF, He isotope ratios (3He/4He) inversely vary with He concentrations, and reflect varied amounts of long- stored, radiogenic He added to the magmatic endmember within the crust. Similarly, addition of CH4 from organic-rich sediments is common in the eastern thermal areas at Yellowstone. Overall, Yellowstone gases reflect addition of deep, high-temperature magmatic gas (CO2-rich), lower-temperatures crustal gases (4He- and CH4-bearing), and those gases (N2, Ne, Ar) added

  10. Indoor air pollution caused by geothermal gases

    International Nuclear Information System (INIS)

    Durand, Michael

    2006-01-01

    This paper discusses the little-known but potentially serious indoor air quality problems that may occur where buildings are constructed on geothermal ground. The main problems are related to seepage of carbon dioxide, hydrogen sulphide, radon and other gases from soil cavities directly into indoor air through perforations in the structure. These gases present a health hazard, and hydrogen sulphide, which is particularly corrosive, may cause problems electrical and electronic systems. Counter-measures are not always effective, so developments in such areas should only be undertaken with a clear understanding of site-specific issues and their possible solutions. (author)

  15. Belgrade: Waning houses

    Jakšić Milica

    2002-01-01

    Full Text Available In some streets of Belgrade we can still find old houses, which hold an ancient dream of dignity, comfort and beauty. They probably live their last days, staring somewhere in the distance - into foggy spaces of their forgetfulness. They stand in fragile rows, increasingly dilapidated disappearing one by one, pretty and sad in their loneliness. They fade attacked by winds, by sunshine, by rains, sorrowed by coldness of their empty rooms. We have no right to let them disappear without any remembrance, to allow them to vanish from of our lives, because - if that happens - that will make poorer both our legacy and us for the future. Thus, we must find ways to hold these old houses, to read and understand their messages, to keep the prints of their spirit and shapes. How to achieve that? If it is true that the beauty of the landscape is hidden in the eyes, which look at it, then drawing is certainly one of the modes to record the wonderful secret of these pretty old houses, silently disappearing from the urban life.

His 'morality fairytales', 'fantasies of good will' imbued with belief in restoration of old-new principles, offer complex reflections on an idealised Americanism of the 1930s which have become the foundation of representations of the American political system. The Capraesque narrative - 'a blend of optimism, humor, patriotism, and, to those who really understand his work, (and darkness, despair, and the need to fight for things you care about...'

  17. Radionuclides in house dust

    Energy Technology Data Exchange (ETDEWEB)

    Fry, F A; Green, N; Dodd, N J; Hammond, D J

    1985-04-01

    Discharges of radionuclides from the British Nuclear Fuel plc (BNFL) reprocessing plant at Sellafield in Cumbria have led to elevated concentrations radionuclides in the local environment. The major routes of exposure of the public are kept under review by the appropriate authorising Government departments and monitoring is carried out both by the departments and by BNFL itself. Recently, there has been increasing public concern about general environmental contamination resulting from the discharges and, in particular, about possible exposure of members of the public by routes not previously investigated in detail. One such postulated route of exposure that has attracted the interest of the public, the press and Parliament arises from the presence of radionuclides within houses. In view of this obvious and widespread concern, the Board has undertaken a sampling programme in a few communities in Cumbria to assess the radiological significance of this source of exposure. From the results of our study, we conclude that, although radionuclides originating rom the BNFL site can be detected in house dust, this source of contamination is a negligible route of exposure for members of the public in West Cumbria. This report presents the results of the Board's study of house dust in twenty homes in Cumbria during the spring and summer of 1984. A more intensive investigation is being carried out by Imperial College. (author)

    Full Text Available This study aimed to identify the relationships between green brand dimension (green brand awareness, green brand image, and green brand trust, green perceived value and customer’s intention to use green products. Data was collected through structured survey questionnaire from 384 customers of three hypermarkets in Kuala-Lumpur. Data was analyzed based on multiple regression analysis. The results indicate that there are significant relationships between green brand awareness, green brand trust, green perceived value, and customer’s intention to use green products. However, green brand image was not found to have significant relationship with customer’s intention to use green products. The discussion presented suggestions for marketers and researchers interested in green branding.

  19. Mental health and housing.

    Kari-Koskinen, O; Karvonen, P

    1976-01-01

    With the present trend away from the designing of individual buildings and towards the systematic planning of whole residential communities, it should be possible to take mental health requirements into account at the planning stage. At present, sociologists are all too seldom consulted on matters of residential planning. When discussing the relationship between housing and mental health one cannot restrict oneself only to the external aspects of the house, but rather one must also consider the opportunities available for the members of the family to satisfy their own needs, both within the home and in its immediate surroundings. Factors which may affect residential requirements include geographical location, type and standard of dwelling and time and continuity of occupation. A move between two districts or groups representing different housing norms and values may lead to withdrawal symptoms in the individual. This may arise equally well from the remoteness of the country districts as from the conflicting pressures brought on by the abundance of contacts available in the large towns. Town life tends to heighten susceptibility to neuroses and personality conflicts. The character of a residential area may affect the mental health of its occupants. Faris & Dunham (4), in studying the incidence of various types of mental illness with an urban population, observed that schizophrenia was most common among people who were in some way isolated from social involvement. The striving for spaciousness in residential areas and the creation of a "summer city" or "garden city" image or a "family-centred way of life" may lead to unexpected problems and have a variety of social consequences. Mental health difficulties have been noted, for example, among housewives in "dormitory" towns or suburbs (11). The institutions required by a community may be grouped into four categories, representing the basic needs of its members. These are (1) economic institutions, (2) social and

    Green building design is becoming broadly adopted, with one green building standard reporting over 3.5 billion square feet certified to date. By definition, green buildings focus on minimizing impacts to the environment through reductions in energy usage, water usage, and minimizing environmental disturbances from the building site. Also by definition, but perhaps less widely recognized, green buildings aim to improve human health through design of healthy indoor environments. The benefits related to reduced energy and water consumption are well-documented, but the potential human health benefits of green buildings are only recently being investigated. The objective of our review was to examine the state of evidence on green building design as it specifically relates to indoor environmental quality and human health. Overall, the initial scientific evidence indicates better indoor environmental quality in green buildings versus non-green buildings, with direct benefits to human health for occupants of those buildings. A limitation of much of the research to date is the reliance on indirect, lagging and subjective measures of health. To address this, we propose a framework for identifying direct, objective and leading "Health Performance Indicators" for use in future studies of buildings and health.

  7. Theoretical evaluation of thermal and energy performance of tropical green roofs

    International Nuclear Information System (INIS)

    Tsang, S.W.; Jim, C.Y.

    2011-01-01

    The thermal and energy efficiency of tropical green roofs is assessed by a theoretical model to clarify the contribution of underlying factors. The suitability of 1400 high-rise public housing blocks in Hong Kong for rooftop greening was assessed by remote sensing images. Weather and microclimatic-soil monitoring data of an experimental green roof provided the basis for computations. Roof greening prevented a huge amount of solar energy at 43.9 TJ in one summer from penetrating the buildings to bring significant energy saving. Thermal performance of humid-tropical green roofs, with greater latent heat dissipation, is twice more effective than the temperate ones. The energy balance model shows that solar energy absorption by bare and green roofs depends on shortwave rather than longwave radiation. Heat flux into a building indicates a one-day time lag after a sunshine day. With restricted evapotranspiration, bare roofs have more sensible heat and heat storage than green roofs. The bare roof albedo of 0.15, comparing with 0.30 of green roof, renders 75% higher heat storage. Small increase in convection coefficient from 12 to 16 could amplify 24% and 45% of latent heat dissipation respectively for bare and green roofs. Doubling the soil water availability could halve the heat storage of green roofs. -- Highlights: → We developed a theoretical model to calculate the thermal performance of tropical green roofs. → Bare roofs have more sensible heat and heat storage than green roofs. → Latent heat dissipation of tropical green roofs is twice that of temperate counterparts. → Heat flux through the roof into a building demonstrates a one-day time lag after a long sunshine day. → Green roofs can block 43.9 TJ of solar energy penetration into public housing buildings in one summer.

  12. Fate of Gases generated from Nuclear Wastes

    The backfill materials such as cement, bentonite or crushed rock are used as engineered barriers against groundwater infiltration and radionuclide transport. Gas generation from radioactive wastes is attributed to radiolysis, corrosion of metals, and degradation of organic materials. Corrosion of steel drums and biodegradation of organic materials in L/ILW can generate gas which causes pressure build up and has the potential to compromise the integrity of waste containers and release the radionuclides and other contaminants into the environment. Performance assessment therefore requires a detailed understanding of the source and fate of gas generation and transport within the disposal system. Here we review the sources and fate of various type of gases generated from nuclear wastes and repositories. Studies on modeling of the fate and transport of repository gases primarily deal with hydrogen and CO{sub 2}. Although hydrogen and carbon dioxide are the major gases of concern, microbial transformations of these gases in the subterranean environments could be significant. Metabolism of hydrogen along with the carbon dioxide results in the formation of methane, low molecular weight organic compounds and cell biomass and thus could affect the total inventory in a repository environment. Modeling studies should take into consideration of both the gas generation and consumption processes over the long-term.

    1977-01-01

    The outline of the pilot plant to remove and recover radioactive rare gases generated from nuclear power plants, reprocessing installations for nuclear fuel, nuclear research installations, etc. is described below. Among the studies of various processes such as liquefaction and distillation, absorption into solvents, active carbon adsorption, diaphragm method, etc., the liquefaction and distillation process by rectification at low temperature has been positively developed. It is in the stage of practical application for removing rare gases in waste gases from reprocessing and nuclear power plants. This is the process with high safety and excellent rare gas removing capability. Further research and development have been also made for selective adsorption and desorption method at low temperature which is very efficient as there is no release of long life nuclides such as Krypton-85. Rare gases recovered by the above mentioned removal systems must be stored safely for a long time as their half lives are long and specific radioactivities are high. The study has been made continuously on the storage methods including adsorption in cylinders and remotely automatically sealing storing system. (Kobatake, H.)

  4. Building the green way.

    Science.gov (United States)

    Lockwood, Charles

    2006-06-01

    Just five or six years ago, the term "green building" evoked visions of barefoot, tie-dyed, granola-munching denizens. There's been a large shift in perception. Of course, green buildings are still known for conserving natural resources by, for example, minimizing on-site grading, using alternative materials, and recycling construction waste. But people now see the financial advantages as well. Well-designed green buildings yield lower utility costs, greater employee productivity, less absenteeism, and stronger attraction and retention of workers than standard buildings do. Green materials, mechanical systems, and furnishings have become more widely available and considerably less expensive than they used to be-often cheaper than their standard counterparts. So building green is no longer a pricey experiment; just about any company can do it on a standard budget by following the ten rules outlined by the author. Reliable building-rating systems like the U.S. Green Building Council's rigorous Leadership in Energy and Environmental Design (LEED) program have done much to underscore the benefits of green construction. LEED evaluates buildings and awards points in several areas, such as water efficiency and indoor environmental quality. Other rating programs include the UK's BREEAM (Building Research Establishment's Environmental Assessment Method) and Australia's Green Star. Green construction is not simply getting more respect; it is rapidly becoming a necessity as corporations push it fully into the mainstream over the next five to ten years. In fact, the author says, the owners of standard buildings face massive obsolescence. To avoid this problem, they should carry out green renovations. Corporations no longer have an excuse for eschewing environmental and economic sustainability. They have at their disposal tools proven to lower overhead costs, improve productivity, and strengthen the bottom line.

  5. Is Housing a Health Insult?

    Baker, Emma; Beer, Andrew; Lester, Laurence; Pevalin, David; Whitehead, Christine; Bentley, Rebecca

    2017-05-26

    In seeking to understand the relationship between housing and health, research attention is often focussed on separate components of people's whole housing 'bundles'. We propose in this paper that such conceptual and methodological abstraction of elements of the housing and health relationship limits our ability to understand the scale of the accumulated effect of housing on health and thereby contributes to the under-recognition of adequate housing as a social policy tool and powerful health intervention. In this paper, we propose and describe an index to capture the means by which housing bundles influence health. We conceptualise the index as reflecting accumulated housing 'insults to health'-an Index of Housing Insults (IHI). We apply the index to a sample of 1000 low-income households in Australia. The analysis shows a graded association between housing insults and health on all outcome measures. Further, after controlling for possible confounders, the IHI is shown to provide additional predictive power to the explanation of levels of mental health, general health and clinical depression beyond more traditional proxy measures. Overall, this paper reinforces the need to look not just at separate housing components but to embrace a broader understanding of the relationship between housing and health.

    The introduction of low-impact renewable energy in Canada's electricity supply is being accomplished using a relatively new, market-based initiative called green power marketing. Consumers now have the option of choosing their electricity supplier in two provinces, as a result of electricity market restructuring in those provinces. In some jurisdictions, green power is being offered at a premium price. Green power options are also available in other jurisdictions through the existing vertically integrated power companies. Green power programs are available to residential and commercial sector consumers in Alberta by ENMAX Energy and EPCOR Energy Services Inc. Prince Edward Island (Maritime Electric Company Ltd.) and Saskatchewan (SaskPower) both offer green power programs. The basis for those programs is specific amounts of electricity purchased. The success of the various programs was examined by the Pembina Institute for Appropriate Development, based on installed capacity of green power, consumer enrolment, product design, and environmental benefits. This report presented the results of this evaluation. For the purpose of this report, only those programs in place by the end of 2001 were considered. The environmental impacts of new generation technologies that were implemented as a result of green power marketing programs were analyzed. Historical emission data of the primary generation sources was used as a basis for the investigation and the quantification of the benefits in each province, since different types of power generation are used in the provinces. Greenhouse gases, acid deposition precursors, ground-level ozone precursors, particulate matter, and carbon monoxide are the significant emissions avoided through the use of green power. Included in the emissions reduction analysis in each province considered were life cycle emissions from conventional power sources and green power sources. Alberta, Saskatchewan and Prince Edward Island were the provinces

  7. Environmental Health Disparities in Housing

    The physical infrastructure and housing make human interaction possible and provide shelter. How well that infrastructure performs and which groups it serves have important implications for social equity and health. Populations in inadequate housing are more likely to have environmental diseases and injuries. Substantial disparities in housing have remained largely unchanged. Approximately 2.6 million (7.5%) non-Hispanic Blacks and 5.9 million Whites (2.8%) live in substandard housing. Segregation, lack of housing mobility, and homelessness are all associated with adverse health outcomes. Yet the experience with childhood lead poisoning in the United States has shown that housing-related disparities can be reduced. Effective interventions should be implemented to reduce environmental health disparities related to housing. PMID:21551378

    The advancement of business and social practices based on information and social practices based on information and communication technologies (ICTs) in the last few decades has transformed many, if not most, economies and businesses into e-economies and businesses into e-businesses. For economies, ICTs are increasingly playing a critical role in transforming and generating economic opportunities. Technology has a potential to create sustainable business and society both in grim and green economic times. Especially, the recovery from the current economic crisis is going to lead to more greener and energy efficient industries. Data centers are found to be major culprits in consuming too much energy and generating higher level of CO/sub 2/ in their overall operations. In order to handle the sheer magnitude of today's data, servers have become larger, denser, hotter, and significantly more costly operate using more power than being used earlier. This paper determines the properties and attributes of green IT infrastructures and the way they will be helpful in achieving green sustainable businesses. The proposed attributes and characteristics of green IT using Virtualization technology are very productive and efficient and green, hence reducing the emission of greenhouse gases so that their overall effect on global warming can be reduced or even eliminated. The proposed attributes indicate the qualities of green IT to enhance the proper utilization of hardware and software resources available in the data center. (author)

    British Columbia Hydro, a Crown Corporation embarked on a strategy to become a sustainable energy company in 2001. An integral part of that strategy was to include reliable green and alternative energy sources in its power generation mix. In this framework, green and alternative energy contributes substantially to future investment decisions, revenue and competitive positioning in the market place. This paper presents a case study for green energy resources in the context of British Columbia Hydro. It discusses methods to quantify Greenhouse Emissions and ways to reduce Greenhouse Gases by choosing cleaner power with examples from a demonstration project on Vancouver Island

    The building is located in urban Horsens on CHR. M. Østergaardsvej. Originally it was designed as part of a bigger social housing project and executed in 1956 by architect J. Broch Christensen. The project consisted of 7 very similar blocks but we are mainly focusing on block 6. The original design of the buildings was a traditional danish design with external bricks and roof tiles - all in red. Inside, the apartments were quite typical of that time. Our concept for the new building is to m...
