  11. The Value of Green Infrastructure on Vacant and Residential Land in Roanoke, Virginia

    Directory of Open Access Journals (Sweden)

    Gunwoo Kim

    2016-03-01

    Full Text Available Using the City of Roanoke, Virginia as a study site, this paper quantifies the forest structure, ecosystem services and values of vacant and residential land. Single family residential land had more trees (1,683,000 than vacant land (210,000 due largely to the differences in land area (32.44 km2 of vacant land vs. 57.94 km2 residential. While the percentage of tree coverage was almost identical across land uses (30.6% in vacant to 32.3% in residential, the number of trees per ha is greater on residential land (290.3 than on vacant land (63.4. The average healthy leaf surface area on individual trees growing on vacant land was greater than that of individual trees on residential land. The fact that trees in vacant land were found to provide more ecosystem services per tree than residential trees was attributed to this leaf area difference. Trees on vacant land are growing in more natural conditions and there are more large trees per ha. Assessing the forest structure and ecosystem services of Roanoke’s vacant and residential land provides a picture of the current extent and condition of the vacant and residential land. Understanding these characteristics provides the information needed for improved management and utilization of urban vacant land and estimating green infrastructure value.

  12. Vacant habitats in the Universe.

    Science.gov (United States)

    Cockell, Charles S

    2011-02-01

    The search for life on other planets usually makes the assumption that where there is a habitat, it will contain life. On the present-day Earth, uninhabited habitats (or vacant habitats) are rare, but might occur, for example, in subsurface oils or impact craters that have been thermally sterilized in the past. Beyond Earth, vacant habitats might similarly exist on inhabited planets or on uninhabited planets, for example on a habitable planet where life never originated. The hypothesis that vacant habitats are abundant in the Universe is testable by studying other planets. In this review, I discuss how the study of vacant habitats might ultimately inform an understanding of how life has influenced geochemical conditions on Earth. Copyright © 2010 Elsevier Ltd.

  18. Artificial Metalloproteins Exploiting Vacant Space: Preparation, Structures, and Functions

    Science.gov (United States)

    Abe, Satoshi; Ueno, Takafumi; Watanabe, Yoshihito

    Molecular design of artificial metalloproteins is one of the most attractive subjects in bioinorganic chemistry. Protein vacant space has been utilized to prepare metalloproteins because it provides a unique chemical environment for application to catalysts and to biomaterials bearing electronic, magnetic, and medical properties. Recently, X-ray crystal structural analysis has increased in this research area because it is a powerful tool for understanding the interactions of metal complexes and protein scaffolds, and for providing rational design of these composites. This chapter reviews the recent studies on the preparation methods and X-ray crystal structural analyses of metal/protein composites, and their functions as catalysts, metal-drugs, etc.

    2011-12-01

    Greening of vacant urban land may affect health and safety. The authors conducted a decade-long difference-in-differences analysis of the impact of a vacant lot greening program in Philadelphia, Pennsylvania, on health and safety outcomes. "Before" and "after" outcome differences among treated vacant lots were compared with matched groups of control vacant lots that were eligible but did not receive treatment. Control lots from 2 eligibility pools were randomly selected and matched to treated lots at a 3:1 ratio by city section. Random-effects regression models were fitted, along with alternative models and robustness checks. Across 4 sections of Philadelphia, 4,436 vacant lots totaling over 7.8 million square feet (about 725,000 m(2)) were greened from 1999 to 2008. Regression-adjusted estimates showed that vacant lot greening was associated with consistent reductions in gun assaults across all 4 sections of the city (P vandalism in 1 section of the city (P < 0.001). Regression-adjusted estimates also showed that vacant lot greening was associated with residents' reporting less stress and more exercise in select sections of the city (P < 0.01). Once greened, vacant lots may reduce certain crimes and promote some aspects of health. Limitations of the current study are discussed. Community-based trials are warranted to further test these findings.

    2016-05-01

    Full Text Available This study reviews scholarly papers and case studies on urban vacant land to gain a stronger understanding of its public value in terms of the ecological and social benefits it can bring. This literature review offers a conceptual overview of the potential benefits of vacant land with the goal of addressing gaps in knowledge about vacant land and to provide suggestions to planners and designers on how vacant properties can be integrated with other green infrastructure in cities. There are many opportunities to redevelop vacant land to enhance its ecological and social value, and many design professionals and scholars are becoming interested in finding new ways to exploit this potential, especially with regard to planning and design. A better appreciation of the public value of urban vacant land is vital for any effort to identify alternative strategies to optimize the way these spaces are utilized for both short-term and long-term uses to support urban regeneration and renewal. This study will help planners and designers to understand and plan for urban vacant land, leading to better utilization of these spaces and opening up alternative creative approaches to envisioning space and landscape design in our urban environments.

  11. Experimental plan for the Single-Family Study

    Energy Technology Data Exchange (ETDEWEB)

    1991-09-01

    The national evaluation of the Weatherization Assistance Program (WAP) consists of five separate studies. The Single-Family Study is one of three studies that will estimate program energy savings and cost effectiveness in principal WAP submarkets. This report presents the experimental plan for the Single-Family Study, which will be implemented over the next three years (1991--1993). The Single-Family Study will directly estimate energy savings for a nationally representative sample of single-family and small multifamily homes weatherized in the 1989 program year. Savings will be estimated from gas and electric utility billing records using the Princeton Scorekeeping Method (PRISM). The study will also assess nonenergy impacts (e.g., health, comfort, safety, and housing affordability), estimate cost effectiveness, and analyze factors influencing these outcomes. For homes using fuels such as wood, coal, fuel oil, kerosene, and propane as the primary source of space conditioning, energy savings will be studied indirectly. The study will assemble a large nationally representative data base. A cluster sampling approach will be used, in which about 400 subgrantees are selected in a first stage and weatherized homes are selected in a second range. To ensure that the Single-Family Study is able to identify promising opportunities for future program development, two purposively selected groups of subgrantees will be included: (1) subgrantees that install cooling measures (such as more efficient air conditioning equipment or radiant barriers), and (2) exemplary subgrantees that use state-of-the-art technologies and service delivery procedures (such as advanced audit techniques, blower door tests, infrared scanners, extensive client education, etc.). These two groups of subgrantees will be analyzed to identify the most effective program elements in specific circumstances. 14 refs., 4 figs., 3 tabs.

    2010-01-01

    This paper presents a strategy for a simple demand controlled ventilation system for single family houses where all sensors and controls are located in the air handling unit. The strategy is based on sensing CO2-concentration and moisture content in the outdoor air and exhaust air. The CO2......-concentration is used to ensure adequate ventilation during occupancy and the moisture content is used to ensure adequate removal of moisture produced in the house. The ventilation rate can be switched between two flow rates: a high rate and a low rate. The high flow rate is based on existing requirements...... in the Danish building regulations and the low flow rate is based on minimum requirements in indoor air quality standards. Measurements were performed on an existing single family house where the controls were installed on the existing mechanical ventilation system. The results showed that the ventilation can...

  15. Tobin's q for Danish single-family houses

    DEFF Research Database (Denmark)

    Haagerup, Christian Deichmann

    The rising price of single-family houses in Denmark and it's relation to the activity in the construction sector has given renewed interest in the theory of Tobin's q. Prices for single-family houses in Denmark have risen by 153 percent from 1993 to 2007 in real terms, with a particular steep rise...... from 2003 to 2006. The activity in the construction sector has been increasing too, but with some time lag caused by what seems to be an inelastic supply. In the long run, house prices will be determined by the replacement cost of houses, e.g. the cost of constructing a similar house including the cost...... of land. This can be used as a guide as to how much prices are to fall, in order to bring them back to the fundamental value. It can also be seen as a warning or indication of a price bubble.

    Urban decline, disinvestment, and blight have not traditionally been addressed by the environmental conservation movement. In this article, we describe an environmental justice-focused intervention located in Pittsburgh, Pennsylvania, that aimed to increase community empowerment to address urban environmental injustices by training residents to reclaim vacant land. We use a case study approach to illustrate resident perceptions of the impact of vacant land and urban decay. The results suggest that these residents viewed vacancy as an important indicator of community well-being and social inequality. We use a social and environmental justice framework to describe results and implications for practitioners and researchers.

    Knowing where vacant taxis are and will be at a given time and location helps the users in daily planning and scheduling, as well as the taxi service providers in dispatching. In this paper, we present a predictive model for the number of vacant taxis in a given area based on time of the day, day of the week, and weather condition. The history is used to build the prior probability distributions for our inference engine, which is based on the naïve Bayesian classifier with developed error-based learning algorithm and method for detecting adequacy of historical data using mutual information. Based on 150 taxis in Lisbon, Portugal, we are able to predict for each hour with the overall error rate of 0.8 taxis per 1x1 km2 area.

  11. Towards Regenerated and Productive Vacant Areas through Urban Horticulture: Lessons from Bologna, Italy

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available In recent years, urban agriculture has been asserting its relevance as part of a vibrant and diverse food system due to its small scale, its focus on nutrition, its contribution to food security, its employment opportunities, and its role in community building and social mobility. Urban agriculture may also be a tool to re-appropriate a range of abandoned or unused irregular spaces within the city, including flowerbeds, roundabouts, terraces, balconies and rooftops. Consistently, all spaces that present a lack of identity may be converted to urban agriculture areas and, more specifically, to urban horticulture as a way to strengthen resilience and sustainability. The goal of this paper is to analyse current practices in the requalification of vacant areas as urban gardens with the aim of building communities and improving landscapes and life quality. To do so, the city of Bologna (Italy was used as a case study. Four types of vacant areas were identified as places for implementing urban gardens: flowerbeds along streets and squares, balconies and rooftops, abandoned buildings and abandoned neighbourhoods. Six case studies representing this variety of vacant areas were identified and evaluated by collecting primary data (i.e., field work, participant observations and interviews and performing a SWOT analysis. For most cases, urban horticulture improved the image and quality of the areas as well as bringing numerous social benefits in terms of life quality, food access and social interaction among participants. Strong differences in some aspects were found between top-down and bottom-up initiatives, being the later preferable for the engagement of citizens. Policy-making might focus on participatory and transparent planning, long-term actions, food safety and economic development.

    2014-01-01

    We assessed the potential for vacant lots and other non-residential settings to serve as source environments for Aedes (Stegomyia) aegypti (L.) in Mérida City, México. Mosquito immatures were collected, during November 2011 – June 2013, from residential premises (n = 156 site visits) and non-residential settings represented by vacant lots (50), parking lots (18), and streets/sidewalks (28). Collections totaled 46,025 mosquito immatures of 13 species. Ae. aegypti was the most commonly encountered species accounting for 81.0% of total immatures, followed by Culex quinquefasciatus Say (12.1%). Site visits to vacant lots (74.0%) were more likely to result in collection of Ae. aegypti immatures that residential premises (35.9%). Tires accounted for 75.5% of Ae. aegypti immatures collected from vacant lots. Our data suggest that vacant lots should be considered for inclusion in mosquito surveillance and control efforts in Mérida City, as they often are located near homes, commonly have abundant vegetation, and frequently harbor accumulations of small and large discarded water-holding containers that we now have demonstrated to serve as development sites for immature mosquitoes. Additionally, we present data for associations of immature production with various container characteristics, such as storage capacity, water quality and physical location in the environment.

    2016-12-01

    Full Text Available In Japan, local cities experience a number of problems related to deterioration of residential environment, quality of public service, and vitalization of commercial land. Specifically, the presence of large vacant lots behind sizable stores, office buildings, hospitals, and factories devitalize urban activity and its landscape. Many local cities are seeking to actualize a sustainable compact city with an integrated population, commerce, traffic and other public services in ways that promote a low carbon and energy-conserving society. Against the backdrop of these issues, this study examines the occurrence of large vacant lots and their utilization by local governments in Japan based on a questionnaire and field survey. It highlights several cases in which a large vacant lot is used to forward the development of a compact city by a local government.

    The study examines the feasibility of incorporating the use of earth-coupled heat pump technology in single-family housing rehabilitation projects, based on energy conservation attributes and financial considerations. Following evaluation of a theoretical model which indicated that installations of the heat pumps were feasible, the heat pumps were tested under actual conditions in five single family housing units which were part of the Urban Homesteading Program, and were matched with comparable units which did not receive special treatment. Energy consumption information was collected for all units for twelve months. Variables were identified, and the data was analyzed for individual housing units and compared with the results predicted by the theoretical model to determine the practicality of incorporating such technology in large scale rehabilitation projects. 14 refs., 14 figs., 3 tabs.

  12. National impacts of the Weatherization Assistance Program in single-family and small multifamily dwellings

    Energy Technology Data Exchange (ETDEWEB)

    Brown, M.A.; Berry, L.G.; Balzer, R.A.; Faby, E.

    1993-05-01

    Since 1976, the US Department of Energy (DOE) has operated one of the largest energy conservation programs in the nation -- the low-income Weatherization Assistance Program. The program strives to increase the energy efficiency of dwellings occupied by low-income persons in order to reduce their energy consumption, lower their fuel bills, increase the comfort of their homes, and safeguard their health. It targets vulnerable groups including the elderly, people with disabilities, and families with children. The most recent national evaluation of the impacts of the Program was completed in 1984 based on energy consumption data for households weatherized in 1981. DOE Program regulations and operations have changed substantially since then: new funding sources, management principles, diagnostic procedures, and weatherization technologies have been incorporated. Many of these new features have been studied in isolation or at a local level; however, no recent evaluation has assessed their combined, nationwide impacts to date or their potential for the future. In 1990, DOE initiated such an evaluation. This evaluation is comprised of three ``impact`` studies (the Single-Family Study, High-Density Multifamily Study, and Fuel-Oil Study) and two ``policy`` studies. Altogether, these five studies will provide a comprehensive national assessment of the Weatherization Assistance Program as it existed in the 1989 Program Year (PY 1989). This report presents the results of the first phase of the Single-Family Study. It evaluates the energy savings and cost effectiveness of the Program as it has been applied to the largest portion of its client base -- low-income households that occupy single-family dwellings, mobile homes, and small (2- to 4-unit) multifamily dwellings. It is based upon a representative national sample that covers the full range of conditions under which the program was implemented in PY 1989.

    White sponge nevus (WSN) is an interesting hereditary oral mucosal disorder that commonly manifests as bilaterally symmetrical, thickened white, corrugated or velvety, diffuse plaques that predominantly affects the buccal mucosa. The lesions may develop at birth or later in childhood or adolescence. Because it is asymptomatic and benign, WSN requires no treatment. Recognition of this disorder is important due to its potential confusion with other lesions that may be found in the oral cavity. Emphasis should be given to the early and correct diagnosis of this disorder to avoid unnecessary treatment. This report presents three affected members of a single family. PMID:27601826

    2008-03-01

    We estimate spatiotemporal models of average neighborhood single family home prices to use in predicting individual property prices. Average home-price variations are explained in terms of changes in average neighborhood house attributes, spatial attributes, and temporal economic variables. Models adopting three different definitions of neighborhoods are estimated with quarterly cross-sectional data over the period 2000 2004 from four cities in Southern California. Heteroscedasticity and autocorrelation problems are detected and adjusted for via a sequential routine. Results of these models suggest that forecasts obtained using city neighborhood average price equations may have advantage over forecasts obtained using city aggregated price equations.

  16. On the thermal inertia and time constant of single-family houses

    Energy Technology Data Exchange (ETDEWEB)

    Hedbrant, J.

    2001-08-01

    Since the 1970s, electricity has become a common heating source in Swedish single-family houses. About one million small houses can use electricity for heating, about 600.000 have electricity as the only heating source, A liberalised European electricity market would most likely raise the Swedish electricity prices during daytime on weekdays and lower it at other times. In the long run, electrical heating of houses would be replaced by fuels, but in the shorter perspective, other strategies may be considered. This report evaluates the use of electricity for heating a dwelling, or part of it, at night when both the demand and the price are low. The stored heat is utilised in the daytime some hours later, when the electricity price is high. Essential for heat storage is the thermal time constant. The report gives a simple theoretical framework for the calculation of the time constant for a single-family house with furniture. Furthermore the comfort time constant, that is, the time for a house to cool down from a maximum to a minimum acceptable temperature, is derived. Two theoretical model houses are calculated, and the results are compared to data from empirical studies in three inhabited test houses. The results show that it was possible to store about 8 kWh/K in a house from the seventies and about 5 kWh/K in a house from the eighties. The time constants were 34 h and 53 h, respectively. During winter conditions with 0 deg C outdoor, the 'comfort' time constants with maximum and minimum indoor temperatures of 23 and 20 deg C were 6 h and 10 h. The results indicate that the maximum load-shifting potential of an average single family house is about 1 kw during 16 daytime hours shifted into 2 kw during 8 night hours. Upscaled to the one million Swedish single-family houses that can use electricity as a heating source, the maximum potential is 1000 MW daytime time-shifted into 2000 MW at night.

    Full Text Available Given the relatively high mobility of individuals at the level of the European Union, as an expression of the free movement of people, it is necessary to have an evaluation of the EU legislation in the area of unclaimed/vacant inheritances. The necessity for this evaluation results out of the fact that the state, through its public authorities, collects this category of inheritances, becoming, following some special provisions, the owner of mobile and immobile goods. Also, the state will become the holder of rights and obligations in connection to these goods, having the obligation to secure the juridical protection of these goods as well as having the right to collect the benefits of the inherited goods.

  19. Selected cost considerations for geothermal district heating in existing single-family residential areas

    Energy Technology Data Exchange (ETDEWEB)

    Rafferty, K.

    1996-06-01

    In the past, district heating (geothermal or conventionally fueled) has not been widely applied to the single-family residential sector. Low-heat load density is the commonly cited reason for this. Although it`s true that load density in these areas is much lower than for downtown business districts, other frequently overlooked factors may compensate for load density. In particular, costs for distribution system installation can be substantially lower in some residential areas due to a variety of factors. This reduced development cost may partially compensate for the reduced revenue resulting from low-load density. This report examines cost associated with the overall design of the system (direct or indirect system design), distribution piping installation, and customer branch lines. It concludes with a comparison of the costs for system development and the revenue from an example residential area.

    1981-08-01

    The extent to which certain energy conservation modifications to the envelope design of a new, single family house are economically justified for a wide range of climates and projected energy costs were investigated factors that give rise to space heating and cooling loads in buildings are provided thermal inter-dependencies within and among envelope components that can greatly affect heating and cooling loads are examined. Economic criteria for determining a minimum life cycle cost building envelope design are formulated and a priority ranking method is developed to assist in the calculation of these designs. An expanded version of the NBS load determination program is used to calculated the annual heating and cooling requirements and maximum heating and cooling loads for a 1200 square foot, wood frame house with a wide range of thermal improvements in 14 geographic locations. It is demonstrated that the optimal envelope design configuration varies over a wide rang depending on climate, energy costs, and modification costs.

    Science.gov (United States)

    The Houston Construction Company solar energy system is designed to provide 62 percent of the space heating and domestic hot water energy requirements for a single-family detached residence containing 1796 square feet. The residence is in Eden Prairie, MN. Energy collection is accomplished by 468 square feet of Solaron flat-plate collectors which face south at an angle of 60 degrees from the horizontal. air is the medium for transfer of solar energy from the collectors to either the conditioned space or storage. Storage is a 314 cubic foot bin containing approximately 24,000 lbs of crushed rock located in a utility room. when solar energy is inadequate to satisfy the requirements of the space heating subsystem, auxiliary thermal energy is supplied from an 80,000 Btu per hour natural gas furnace. Domestic hot water is provided by a 30,000 Btu per hour natural gas water heater if the solar contribution is insufficient.

    , modern SWPs, such as I-joists, LVL, and OSB, have replaced lumber and plywood products. The needs of the US single family housing industry have been met by a smaller mass of SWPs per unit area constructed. The mass of SWP present in construction wastes was influenced strongly by building cycles....... Production of construction waste peaked in 2005, when 3.31 million tonnes of SWPs were produced by 1.72 million single family housing starts. It diminished to 0.874 million tonnes of SWPs as the housing starts fell to 445,000 in 2009. In contrast, the mass of demolition wastes produced was affected...... substantially by the number of houses in the stock and their half-lives. Approximately 4.5 million tonnes of SWP demolition waste were produced in 2010, and in the same year, the stock of SWPs in US single family homes reached 1,220 million tonnes. © Forest Products Society 2012....

    1991-02-01

    The energy bill for US single-family households was over $77 billion in 1987 (excluding auto fuel purchases), accounting for approximately 20% of national energy expenditures. Large sums are spent on residential retrofits by individual homeowners, government agencies, and utilities. As of late 1987, over 21 million households indicated that they had added at least one energy-saving measure in the previous two years, while a recent Electric Power Research Institute (EPRI) study estimated that nearly 15 million residential customers have participated in some kind of demand-side management (DSM) program. Given the level of continuing investments in residential energy efficiency, accurate estimates of savings from various conservation measures are increasingly necessary, especially as new technologies become more sophisticated and incremental efficiency gains more difficult to achieve. This report provides a comparative analysis of measured data on the performance and cost-effectiveness of energy-saving measures in existing single-family homes, based on information in the Buildings Energy-Use Compilation and Analysis (BECA) data base. The initial BECA report on measured data for single-family retrofits was completed seven years ago. In updating the single-family database, we have added 135 data points, representing over 33,000 houses, to the original database of 145 retrofit projects. The report is organized in two volumes. Volume 1 provides a summary of energy savings and costs of individual retrofit measures and strategies and results from federal/state low-income and utility weatherization programs. we also discuss measurement issues, predicted versus actual savings, trends in single-family retrofit programs, and implications for the next generation'' of cost-effective single-family retrofits. Volume 2 contains a written summary of each retrofit project and complete data tables. 87 refs., 20 figs., 16 tabs.

    As regulatory pressure to reduce the environmental impact of urban stormwater intensifies, US municipalities increasingly seek a dedicated source of funding for stormwater programs, such as a stormwater utility. In rare instances, single family residences are eligible for utility discounts for installing green infrastructure. This study examined the hydrologic and economic efficacy of four such programs at the parcel scale: Cleveland (OH), Portland (OR), Fort Myers (FL), and Lynchburg (VA). Simulations were performed to model the reduction in stormwater runoff by implementing bioretention on a typical residential property according to extant administrative rules. The EPA National Stormwater Calculator was used to perform pre- vs post-retrofit comparisons and to demonstrate its ease of use for possible use by other cities in utility planning. Although surface slope, soil type and infiltration rate, impervious area, and bioretention parameters were different across cities, our results suggest that modeled runoff volume was most sensitive to percent of total impervious area that drained to the bioretention cell, with soil type the next most important factor. Findings also indicate a persistent gap between the percentage of annual runoff reduced and the percentage of fee reduced.

    The National Savings and Loan League (NSLL) has been researching techniques that may be used to finance energy-conservation measures in the residential sector. Twelve techniques developed and tested by NSLL are: future-advances clause under open-end mortgages; borrowing against existing savings accounts; home-improvement loans; variable-rate mortgages; second trusts or second mortgages; variable-payment mortgages; balloon-payment mortgages; deferred monthly payments for periods of excessive energy use; renegotiation of terms at set intervals; lower interest rates offered on mortgages in return for lender sharing in equity appreciation of the property; graduated payments; and deferred-interest loans. The testing took place in Pittsburgh, PA. The program consisted of 8 specific tasks, including several directed at different financial innovations for the financing of retrofits. Details are presented on findings; legal research; relationship of utilities to installation of retrofits; financing techniques applicable to retrofits; and national energy program for single-family residences. Some extensive attachments include information on: legal aspects, energy loan advertisements, and potential savings to be realized from various residential retrofit energy-conservation measures.

  13. Building America Case Study: Indirect Solar Water Heating Systems in Single-Family Homes, Greenfield, Massachusetts

    Energy Technology Data Exchange (ETDEWEB)

    2016-04-01

    Solar water heating systems are not new, but they have not become prevalent in most of the U.S. Most of the country is cold enough that indirect solar thermal systems are required for freeze protection, and average installed cost of these systems is $9,000 to $10,000 for typical systems on single-family homes. These costs can vary significantly in different markets and with different contractors, and federal and regional incentives can reduce these up-front costs by 50% or more. In western Massachusetts, an affordable housing developer built a community of 20 homes with a goal of approaching zero net energy consumption. In addition to excellent thermal envelopes and PV systems, the developer installed a solar domestic water heating system (SDHW) on each home. The Consortium for Advanced Residential Buildings (CARB), a research consortium funded by the U.S. Department of Energy Building America program, commissioned some of the systems, and CARB was able to monitor detailed performance of one system for 28 months.

    Full Text Available Mercury pollution (MeHg up the aquatic food chains in the Amazonian ecosystems has been a major concern in environmental health. Riverside people (ribeirinhos along the Upper Madeira river are heavy fish eaters. Hair is the best biomarker for MeHg exposure. By assuming a constant hair growth rate, it is possible to evaluate a temporal profile of Hg exposure over the recent defined past. In this paper we present the segmental total hair Hg concentrations from a single family from which some of the 10 persons investigated had high hair Hg concentrations (peak of 339 ppm. We also presented the hair MeHg content from 4 out of the 10 family members investigated. There was a wide variation in total hair Hg concentrations (8 to 339 ppm among these individuals, who were mostly sharing their meals; there was also a wide variation in total Hg concentrations in the same individual over time (136 to 274 ppm. Hg speciation showed a mean and standard deviation in the MeHg content of 62% and 6%, respectively. The wide variation in total hair Hg concentration strongly indicated that it is possible to mitigate critical Hg exposure levels by conducting a fish advisory.

    Full Text Available Abstract Background Hypertrophic cardiomyopathy (HCM is an extremely heterogeneous disease. An under recognized and very often missed subgroup within this broad spectrum concerns patients with left ventricular (LV apical aneurysms in the absence of coronary artery disease. Case presentation We describe a case of HCM with midventricular obstruction and apical aneurysm formation in 3 patients coming from a single family. This HCM pattern was detected by 2D-echocardiography and confirmed by cardiac magnetic resonance imaging. A cardioverter defibrillator was implanted in one of the patients because of non-sustained ventricular tachycardia detected in 24-h Holter monitoring and an abrupt drop in systolic blood pressure during maximal exercise test. The defibrillator activated 8 months after implantation by suppression of a ventricular tachycardia providing anti-tachycardia pacing. The patient died due to refractory heart failure 2 years after initial evaluation. The rest of the patients are stable after a 2.5-y follow-up period. Conclusion The detection of apical aneurysm by echocardiography in HCM patients may be complicated. Ventricular tachycardia arising from the scarred aneurysm wall may often occur predisposing to sudden death.

    A growing body of literature examines urban water sustainability with increasing evidence that locally-based physical and social spatial interactions contribute to water use. These studies however are based on single-city analysis and often fail to consider whether these interactions occur more generally. We examine a multi-city comparison using a common set of spatially-explicit water, socioeconomic, and biophysical data. We investigate the relative importance of variables for explaining the variations of single family residential (SFR) water uses at Census Block Group (CBG) and Census Tract (CT) scales in four representative western US cities - Austin, Phoenix, Portland, and Salt Lake City, - which cover a wide range of climate and development density. We used both ordinary least squares regression and spatial error regression models to identify the influence of spatial dependence on water use patterns. Our results show that older downtown areas show lower water use than newer suburban areas in all four cities. Tax assessed value and building age are the main determinants of SFR water use across the four cities regardless of the scale. Impervious surface area becomes an important variable for summer water use in all cities, and it is important in all seasons for arid environments such as Phoenix. CT level analysis shows better model predictability than CBG analysis. In all cities, seasons, and spatial scales, spatial error regression models better explain the variations of SFR water use. Such a spatially-varying relationship of urban water consumption provides additional evidence for the need to integrate urban land use planning and municipal water planning.

    2009-10-01

    The Agaricales is the largest and most diverse order of mushroom-forming Basidiomycota, with over 100 natural groups recognized in recent Fungal Tree of Life studies. Most agarics are either saprotrophic or ectomycorrhizal fungi, but the family Hygrophoraceae is in part characterized by a unique and remarkable diversity of lichenized forms. The most familiar of these is the chlorolichen genus Lichenomphalia, whose phylogenetic position in the Agaricales has been established. Recent limited evidence suggested that Hygrophoraceae also contains cyanolichens in the genus Dictyonema, which indicates a remarkable concentration and diversity of lichen-formers in a single family of agarics. To demonstrate the relationships of lichen-formers to other fungi in the family, we assembled ribosomal sequences from 52 species representing recognized groups within the Hygrophoraceae, among them new sequences representing Acantholichen and most species and forms of Dictyonema. The molecular data were evaluated using parsimony, likelihood, Bayesian, and distance analyses, including coding of ambiguous regions by means of INAASE and ARC, all of which indicate that Dictyonema and Acantholichen form a monophyletic clade derived from the primarily bryophilous genus Arrhenia and sister to the enigmatic Athelia pyriformis, a species unrelated to the Atheliales for which we are proposing a new genus name Eonema. The chlorolichen genus Lichenomphalia may be polyphyletic. Fungi in the Dictyonema-Acantholichen clade are typically tropical, entirely lichenized, and associate with cyanobacterial photobionts. Our data indicate a transition from agaricoid-omphalinoid basidiomes observed in Arrhenia to stereoid-corticioid forms in Dictyonema, and also support a previous suggestion of a connection between loss of clamp connections and lichenization. The diverse basidiome and thallus morphologies and nutritional ecologies of these fungi indicate a remarkable evolutionary flexibility that appears to

  3. The low-income single-family house and the effectiveness of architects in affecting affordability

    2012-12-01

    Full Text Available Architects are increasingly engaged in efforts to provide affordable, owner-occupied housing in the United States. Yet architects’ roles in broadly addressing affordable housing remain marginal as was anecdotally evident by the absence of architects at a recent university-sponsored affordable housing workshop. Apparently, the potential contributions of architects in “the development of innovative approaches and best practices” related to affordable, owner-occupied housing is not always valued to housing policymakers and planners such as those who organized this workshop. This paper speculatively explores the gap between the potential value of architects and their actual effectiveness at realizing widespread relevancy, innovation, and change in improving the quality and attainability of affordable, owner occupied housing and how this gap may contribute to the undervaluation and marginalization of architects’ efforts to address affordable housing needs in the United States. Case studies of several recent U.S. house design competitions exemplify these gaps. Potential strategies for closing these gaps and thus appreciating the value of architects’ efforts in this endeavor are identified.To become central in providing much-needed affordable, owner-occupied housing, architects must make the value of their potential contributions evident. This requires a clear definition of design goals, a rigorous assessment of built projects, and the thorough dissemination of findings and methodologies. Architects must engage those fields to which they have, in the U.S., long relinquished affordable, single-family housing. Architects must demonstrate that qualitative design improvements are not just possible within the frameworks and agendas of those other fields but that good design will better enable the achievement of those extra-disciplinary goals.

    Two models are developed that can estimate derived fuel demands in single-family dwellings, given fixed final demand for space heat by states. One is an extension of a single-period linear programming model of the nation's energy system, the Brookhaven Energy System Optimization Model. In it the demand for single-family space heat is disaggregated by state and type of home-heating system. The other is a multiple-period dynamic programming model of single-family space heat demand, also disaggregated by state and type of system. Preliminary results for each model are presented and compared.

    The quality of the environment is an essential point in the care of preterm newborns. The design of neonatal intensive care units (NICUs) (open-bay, single-patient room, single-family room) directly affects both the preterm newborns and their caregivers (parents, healthcare staff). The aim of this systematic review was to evaluate the impact of single-family rooms on the preterm newborn, its parents, and the staff. Single-family rooms improve outcome for the preterm newborn, with increasing parental involvement and better control of the environment (fewer inappropriate stimulations such as high levels of noise and illumination). This kind of NICU design also improves parental and staff satisfaction.

    Much attention has been paid to hospitals environments since modern pandemics have emerged. The building sector is considered to be the largest world energy consumer, so many global organizations are attempting to create a sustainable environment in building construction by reducing energy consumption. Therefore, maintaining high standards of hygiene while reducing energy consumption has become a major task for hospitals. This study develops a decision model based on genetic algorithms and A* graph search algorithms to evaluate existing hospital environmental conditions and to recommend an optimal scheme of sustainable renovation strategies, considering trade-offs among minimal renovation cost, maximum quality improvement, and low environmental impact.

    Much attention has been paid to hospitals environments since modern pandemics have emerged. The building sector is considered to be the largest world energy consumer, so many global organizations are attempting to create a sustainable environment in building construction by reducing energy consumption. Therefore, maintaining high standards of hygiene while reducing energy consumption has become a major task for hospitals. This study develops a decision model based on genetic algorithms and A* graph search algorithms to evaluate existing hospital environmental conditions and to recommend an optimal scheme of sustainable renovation strategies, considering trade-offs among minimal renovation cost, maximum quality improvement, and low environmental impact. Reusing vacant buildings is a global and sustainable trend. In Taiwan, for example, more and more school space will be unoccupied due to a rapidly declining birth rate. Integrating medical care with local community elder-care efforts becomes important because of the aging population. This research introduces a model that converts a simulated vacant school building into a community public hospital renovation project in order to validate the solutions made by hospital managers and suggested by the system.

    Full Text Available Citizens protest development when they consider it undesirable. One type of development commonly perceived as undesirable by single-family home owners is proximate multifamily housing, often considered a cause of property devaluation. This study assesses multifamily housing, by typology, and its monetary association with proximate single-family housing prices. The research design is a cross-sectional study using multivariate regression. The unit of analysis is the detached single-family dwelling. The study population is a sample taken from all arms-length owner-occupied, primary residence, detached single-family property transactions recorded in Tallahassee-Leon County, Florida, USA, during 2008. The key findings show no statistically significant negative associations between multifamily housing and single-family property selling prices in the sample; in fact, the two were positively correlated. These findings address single-family homeowner concerns about proximate multifamily housing and should bolster the political feasibility of Smart Growth policy, which recommends denser urban infill.

    This study involved the development of a model for evaluating the potential costs and benefits of ozone control by activated carbon filtration in single-family homes. The modeling effort included the prediction of indoor ozone with and without activated carbon filtration in the HVAC system. As one application, the model was used to predict benefit-to-cost ratios for single-family homes in 12 American cities in five different climate zones. Health benefits were evaluated using disability-adjusted life-years and included city-specific age demographics for each simulation. Costs of commercially available activated carbon filters included capital cost differences when compared to conventional HVAC filters of similar particle removal efficiency, energy penalties due to additional pressure drop, and regional utility rates. The average indoor ozone removal effectiveness ranged from 4 to 20% across the 12 target cities and was largely limited by HVAC system operation time. For the parameters selected in this study, the mean predicted benefit-to-cost ratios for 1-inch filters were >1.0 in 10 of the 12 cities. The benefits of residential activated carbon filters were greatest in cities with high seasonal ozone and HVAC usage, suggesting the importance of targeting such conditions for activated carbon filter applications.

    The purpose of this study was to determine whether there were differences in staff quality of work life and parent satisfaction when a neonatal intensive care unit moved from an open-bay design to a single-room model of care. This descriptive study measured staff quality of work life and family satisfaction before and at 2 time periods after the relocation of a perinatal centre and the introduction of single-family room care. Differences in work life quality and satisfaction were determined using 2-sample t-tests. There were improvements in staff quality of work life and family satisfaction at both time periods following the move. Lessons learned may be of value to other units considering such a move. A neonatal intensive care unit designed to contribute to parental and staff well-being is a model to be considered for future neonatal designs.

    Rapid urbanization has accelerated land use and land cover changes, and generated the urban heat island effect (UHI). Previous studies have reported positive effects of neighborhood landscapes on mitigating urban surface temperatures. However, the influence of neighborhood landscape spatial patterns on enhancing cooling effects has not yet been fully investigated. The main objective of this study was to assess the relationships between neighborhood landscape spatial patterns and land surface temperatures (LST) by using multi-regression models considering spatial autocorrelation issues. To measure the influence of neighborhood landscape spatial patterns on LST, this study analyzed neighborhood environments of 15,862 single-family houses in Austin, Texas, USA. Using aerial photos, geographic information systems (GIS), and remote sensing, FRAGSTATS was employed to calculate values of several landscape indices used to measure neighborhood landscape spatial patterns. After controlling for the spatial autocorrelation effect, results showed that larger and better-connected landscape spatial patterns were positively correlated with lower LST values in neighborhoods, while more fragmented and isolated neighborhood landscape patterns were negatively related to the reduction of LST.

    This paper explores how changes in regulatory requirements for energy efficiency in buildings (in the US also known as building energy codes) affect household energy consumption. The focus in this paper is on natural gas consumption by Danish single-family owner-occupied houses. Unlike most other papers investigating household energy consumption this paper uses a unique panel data set constructed by merging several administrative data bases. The data set describes house and household characteristics, outdoor temperature and actual metered natural gas consumption over 6 years (1998-2003). Applying advanced econometric methods we examine differences in heating energy consumption due to different building regulation requirements at the time of house construction. As for the effect of the building regulation, we find that changes in Danish building regulations have led to significant reductions in energy used for heating. The latest revision of the Danish building regulation covered by this paper is that of 1998. This revision has resulted in a 7 percent reduction in natural gas consumption. (Author)

    A vacant niche in alpine habitats of the Krkonoše Mts. (Western Sudetes, Czech Republic) was colonised by a non-native butterfly Erebia epiphron (Lepidoptera: Nymphalidae, Satyrinae) as a result of artificial introduction of 50 females in 1932 and 1933. The species established a large population occupying an entire area above the timberline on one of parallel ridges (East) of the mountains, but it has not yet colonised the parallel Western ridge, which is almost identical in area, altitude and vegetation. We compared altitudinal distribution and adult habitats of the alien species and of its native congener, E. euryale. Distribution of both species was significantly affected by altitude, but habitat type predicted butterfly numbers better than altitude in regression models. The introduced species was sympatric with the native one near the timberline, but its altitudinal optimum was higher, within tundra grasslands, where the native E. euryale did not occur. Peak adult emergence of E. euryale was later than in E. epiphron and followed identical pattern in allopatry. The failure of E. epiphron to colonise the Western ridge is attributable to its incapability to disperse across wooded areas. The Krkonoše alpine communities are unsaturated with species, which is striking in comparison with native butterfly fauna of lower Hrubý Jeseník Mts. We interpret this by a past encroachment of alpine grasslands in the Krkonoše Mts. by the dwarf pine Pinus mugo.

    We found un-occupied dwellings; the vacant houses and the second houses in the map of Hirato castle town on 1792. There were 69 vacant houses belonging to the second houses and 19 vacant houses belonging non-dwellers at Hirato castle town on 1792. There were 937 lots and 79 lodging households at there, then public watch boxis were eleven spots, public wells were four lots and six warehouses on 1792, so the upper limits of households were 995 and the under limits of households were 916 at there. Thus the ratio of the unoccupied houses in total dwellings was between 8.84 % and 9.61 % at Hirato castle town on 1792. the second houses were composed of three elements; 1st was own-using (Kake-Mochi), 2nd was rental houses (Kariya) and 3rd was vacants (kake-mochi Akiya). The own-using houses were thirty-one, the rental houses were thirty-seven and the vacants of the second houses were sixty-nine. The total of the second houses were 137. We couldn't find the names of some owners of the second houses and vacants in Hirato on 1792, perhaps the non-dweller was died without any heir or heiress, or transfered to another town for the some reasons. Sooner or later these unoccupied dwellings belonging non-dwellers in this town would belonged to some citizens in Hirato, therefore these vacants shall enter on their second houses. So these second house shall be divided into own-using, rental houses or vacants. As mentioned above the second houses-or the third and more-were 110 lots, but the four lots owner was only one, the three lots owners were four cases and the two lots owners were ten cases, the single owners were 118 cases. The four lots owner was Kimono Fabric. The three lots owners were three Sake-Brewing and a Dyer, both were subordinative offices. In the cases of two lots owner; Oil Dealer were three and Unknown were two, Sake-Brewing, Wholesale, Dyer, Kimono Fabric and Mason was one. Except two cases of duplicated lots were all subordinative.

    During the winter of 1985-86, a retrofit field test was performed in 66 occupied, low-income, single-family homes in Madison, Wisconsin. The primary objectives of the field test were to (1) determine the measured energy savings and the relative benefits of a combination of envelope and mechanical equipment retrofits that were selected following a new audit-directed retrofit procedure, (2) determine the energy savings and benefits due to performing infiltration reduction work following a recently developed infiltration reduction procedure, and (3) study general occupant behavior and house thermal characteristics and their possible change following retrofit installation. This report provides an overview of the project and summarizes the findings which will be presented in detail in separate reports. Major findings from the field test include: (1) The audit-directed retrofit procedure produced an average savings of 207 therms/year/house. The procedure also more than doubled the overall cost-effectiveness of the low-income weatherization assistance program as compared with the priority system formerly used in Wisconsin. Wall insulation and condensing furnaces were the major retrofits (predicted annual energy savings greater than 100 therms/year) most often selected under the procedure. The respective average energy savings of the houses receiving wall insulation and condensing furnace. s was 14.6 and 14.3 therms/year for each $100 spent on them under the program. (2) The blower-door-guided infiltration reduction procedure reduced expenditures for infiltration reduction to about one-fourth of previous program costs (from $570/house to $106/house). The procedure also reduced the average air leakage rate in the treated houses by 16%, whereas, in a previous study, no significant reduction was found following the installation of typical infiltration reduction measures. (3) Twenty to 60% of the deviation between predicted and measured savings can be attributed to incorrect

    随着城市化进程的推进,城市车辆数量呈现激增的趋势.城市交通为居民的出行提供便利的同时,也带来了比如打车难问题.为了解决这个问题,首先采用对大规模的出租车GPS轨迹数据进行预处理,并生成道路特征索引;然后利用非齐次泊松过程NPP进行预测和推荐工作.用此方法与其它相关先进方法进行对比,实验结果表明,此方法在准确率和运行效率方面更具优势.%With the development of urbanization, the number of cars was proliferating fast. Urban transportation provides convenience for city resident, meanwhile, it also brings many challenges, such as causing a difficulty for taking a taxi. To solve the problem, main work was composed of two parts: first, a method was proposed to estimate the probability and waiting time for a vacant taxi at a given time and place, second, an recommendations was provided for passengers of where to wait for a taxi. In order to complete the main work, the Large-scale Taxi GPS Traces was preprocessed and the road characteristic index was generated. Then NPP ( Nonhomogeneous Poisson Process) was used to predict and recommend. Compared with other related advanced methods, the results show that the method has more advantages in accuracy and efficiency.

  7. Comparing the capitalisation benefits of light-rail transit and overlay zoning for single-family houses and condos by neighbourhood type in metropolitan Phoenix, Arizona.

    Light rail transit (LRT) is increasingly accompanied by overlay zoning which specifies the density and type of future development to encourage landscapes conducive to transit use. Neighbourhood type (based on land use mix) is used to partition data and investigate how pre-existing land use, treatment with a park-and-ride (PAR) versus walk-and-ride (WAR) station and overlay zoning interrelate. Hedonic models estimate capitalisation effects of LRT-related accessibility and overlay zoning on single-family houses and condos in different neighbourhoods for the system in metropolitan Phoenix, Arizona. Impacts differ by housing and neighbourhood type. Amenity-dominated mixed-use neighbourhoods-predominantly WAR communities-experience premiums of 6 per cent for single-family houses and over 20 per cent for condos, the latter boosted an additional 37 per cent by overlay zoning. Residential neighbourhoods-predominantly PAR communities-experience no capitalisation benefits for single-family houses and a discount for condos. The results suggest that land use mix is an important variable to select comparable neighbourhoods.

    Full Text Available Our study was conducted in 2003–2012 in Eastern Ukraine, in the basin of the Seversky Donets river. The total surveyed area was ca. 900 km2 of nesting habitats suitable for raptors. A total of 69 vacant nests were found, i.e. 33.2 % of the total number of nests (208. Nests occupied by recipient species, i.e. the so-called ‘effective nest pool’, were 23–24, i.e. 33.3–34.7 % of the pool of available nests. Up to 25 % of all pairs of raptors depend on the availability of vacant nests of heterospecifics. Ravens (Corvus corax are the most significant donors of nests: 42.5 % of the pool of available nests is built by this species, and more than 60 % of them are occupied by recipient species. Common Buzzard (Buteo buteo comes second with 26.09 and 58.3 %, respectively. The most common recipients of nests are Hobbies (Falco subbuteo, Common Kestrel (Falco tinnunculus and Booted Eagles (Hieraaetus pennatus. The most significant factors that govern occupation of vacant nests by recipient species are: availability of nests in the marginal zone of forest plots, i.e. within 500 m from the forest edge, large distance from human settlements (>1500 m, presence of nests located on trees in the canopy storey, and mature and submature age of forest stands. For seven species considered in our research (n=227, the most important factors were position of nests, in the forest canopy layer, no logging activity within300 m of the nest, no regular human disturbance, and presence of “windows” in the canopy made by fallen trees.

    Quantitative trait locus (QTL) mapping has been used to dissect the genetic architecture of complex traits and predict phenotypes for marker-assisted selection. Many QTL mapping studies in plants have been limited to one biparental family population. Joint analysis of multiple biparental families offers an alternative approach to QTL mapping with a wider scope of inference. Joint-multiple population analysis should have higher power to detect QTL shared among multiple families, but may have lower power to detect rare QTL. We compared prediction ability of single-family and joint-family QTL analysis methods with fivefold cross-validation for 6 diverse traits using the maize nested association mapping population, which comprises 25 biparental recombinant inbred families. Joint-family QTL analysis had higher mean prediction abilities than single-family QTL analysis for all traits at most significance thresholds, and was always better at more stringent significance thresholds. Most robust QTL (detected in >50% of data samples) were restricted to one family and were often not detected at high frequency by joint-family analysis, implying substantial genetic heterogeneity among families for complex traits in maize. The superior predictive ability of joint-family QTL models despite important genetic differences among families suggests that joint-family models capture sufficient smaller effect QTL that are shared across families to compensate for missing some rare large-effect QTL.

    Full Text Available The construction and building process depends on substantial consumption of natural resources with far-reaching impacts beyond their development area. In general, a significant portion of annual resource consumption by the building and construction industry is a result of applying traditional building strategies and practices such as designing and selecting types of development (e.g. multi-unit condo and single-family house, etc., building materials and structure, heating/cooling systems, and planning renovation and maintenance practices. On the other hand, apart from structural suitability, building developers mostly consider the basic requirements of public owners or private occupants of the buildings, where the main criteria for selecting building strategies are costs, and long-term environmental and socio-economic impacts are generally ignored. The main purpose of this paper is to develop an improved building sustainability assessment framework to measure and integrate different sustainability factors, i.e. long-term environmental upstream and downstream impacts and associated socio-economic costs, in a unified and quantitative basis. The application of the proposed framework has been explained through a case study of single-family houses and multi-unit residential buildings in Canada. A comprehensive framework based on the integration of emergy synthesis and life cycle assessment (LCA has been developed and applied. The results of this research prove that the proposed emergy-based life cycle assessment (Em-LCA framework offers a practical sustainability assessment tool by providing quantitative and transparent results for informed decision-making.

    There are about 1.1 million single-family houses in Finland. 75% of these houses were built before year 1990. Majority of the houses remain at the energy- and eco-efficiency level of their construction time. If all of these houses were renovated to meet the state-of-the- art energy-efficiency requirements, the savings in nationwide consumption of heating energy would be 11.8 TWh. There are lots of typical single-family houses in the Finnish housing stock from the construction period. Renovation concepts with typical solutions can be developed for these typical houses. However, it must always be ensured that the selected concept suits the particular house. Comprehensive, full-service or one-stop-shop service models can be developed based on the renovation concepts. These may also include other services such as a building condition survey or a study, energy certificate, equipment and system installations, financial services, operation and maintenance services, and energy-monitoring and consumption analysis. It is natural to connect the one-stop-shop service model into the renovation process. The process includes stages for marketing, preliminary building inspection and energy audit, a detailed building inspection and energy analysis, a proposal for an integrated solution, the actual repair work, and quality assurance and continuous commissioning. Different stages involve different actors and service providers. There are several options for which type of organization or agent takes the main responsibility for the one-stop-shop service. Depending on the responsible organization, the content provider's business model and priorities differ. The one-stop-shop services business has been a narrow part of actors' whole business, so far. Some actors have already stopped providing the services, either due to the lack of demand or unprofitableness of the services. In an ideal model, the value promise and the main features of the model are the same, but the service

    Full Text Available Björn Lemmer Institute of Experimental and Clinical Pharmacology and Toxicology, Ruprecht-Karls-University of Heidelberg, Mannheim, Germany Abstract: This is the first report in which seasonal patterns in nativity and mortality were analyzed in a single family, branches of which have resided in the middle of Europe as well as in South Africa for several hundreds of years. The family included a total of 3,645 members. The data convincingly demonstrate the effect of the seasonal amplitude of the photoperiod, as represented by the different latitudes, on the seasonal rhythm in nativity and mortality, discernible from 1500–1950 in Europe at 51° N but not in South Africa at 30° S. Most interestingly, this pattern in Germany was lost in the second half of the 20th century, possibly because of socioeconomic conditions and masking effects from the introduction of new technology to better control environmental conditions, greater use of artificial light, further incorporation of shiftwork schedules in industry, stronger advances in medical treatment of many diseases (including increased availability of intensive care in hospitals, and finally, greater longevity of the population.

    2013-02-01

    Full Text Available System cost reductions and development of standardised plug-and-function systems are some of the most important goals for solar heating technology development. Retrofitting hot water boilers in single-family houses when installing solar collectors has the potential to significantly reduce both material and installation costs. In this study, the TRNSYS simulation models of the retrofitting solar thermal system were validated against measurements. Results show that the validated models are in good agreement with measurements. On an annual basis a deviation of 2.5% out of 1099 kWh was obtained between the auxiliary energy from results and from the simulation model for a complete system. Using the validated model a system optimization was carried out with respect to control strategies for auxiliary heating, heat losses and volume of auxiliary storage. A sensitivity analysis was carried out regarding different volumes of retrofitted hot water boiler, DHW profiles and climates. It was estimated that, with adequate improvements, extended annual solar fractions of 60%, 78% and 81% can be achieved for Lund (Sweden, Lisbon (Portugal and Lusaka (Zambia, respectively. The correspondent collector area was 6, 4 and 3 m2, respectively. The studied retrofitted system achieves a comparable performance with conventional solar thermal systems with the potential to reduce the investment cost.

    Full Text Available One of the biggest obstacles to economic profitability of solar water heating systems is the investment cost. Retrofitting existing domestic hot water heaters when a new solar hot water system is installed can reduce both the installation and material costs. In this study, retrofitting existing water heaters for solar water heating systems in Swedish single-family houses was theoretically investigated using the TRNSYS software. Four simulation models using forced circulation flow with different system configurations and control strategies were simulated and analysed in the study. A comparison with a standard solar thermal system was also presented based on the annual solar fraction. The simulation results indicate that the retrofitting configuration achieving the highest annual performance consists of a system where the existing tank is used as storage for the solar heat and a smaller tank with a heater is added in series to make sure that the required outlet temperature can be met. An external heat exchanger is used between the collector circuit and the existing tank. For this retrofitted system an annual solar fraction of 50.5% was achieved. A conventional solar thermal system using a standard solar tank achieves a comparable performance for the same total storage volume, collector area and reference conditions.

    Multi-family therapy (MFT) has yet to be evaluated in families of adults with anorexia nervosa (AN). The study aims were: (i) assess the feasibility of MFT for AN; and, (ii) assess whether MFT is associated with improved outcomes for families compared with single-family therapy (SFT). Adult patients with AN consecutively referred to an eating disorder treatment program were assigned (non-randomly) to receive eight sessions of SFT or MFT. Assessment occurred pre-therapy, immediately post-therapy, and at 3-month follow-up. A total of 37 female patients (13 SFT, 24 MFT) and 45 family members (16 SFT, 29 MFT) completed treatment. There were significant time effects for patients' BMI, eating disorder-related psychopathology and multiple family outcome measures. There were no differences between MFT and SFT on family outcome measures at end of treatment and 3 months post treatment. MFT is a feasible intervention that can be used in adult intensive treatment for those with AN.

  8. Retrofitted Solar Domestic Hot Water Systems for Swedish Single-Family Houses—Evaluation of a Prototype and Life-Cycle Cost Analysis

    2016-11-01

    Full Text Available According to recent technology road maps, system cost reductions and development of standardised plug-and-function systems are some of the most important goals for solar heating technology development. Retrofitting hot water boilers in single-family houses when installing solar collectors has the potential to significantly reduce both material and installation costs. Previous studies have investigated such retrofitting, using theoretical simulations and laboratory tests, but no actual installations were made and tested in practice. This article describes the installation, measured performance and cost effectiveness of a retrofitting solution that converts existing domestic hot water heaters to a solar domestic hot water system. The measured performance is characterised by the monthly and annual solar fractions. The cost effectiveness is evaluated by a life-cycle cost analysis, comparing the retrofitted system to a conventional solar domestic hot water system and the case without any solar heating system. Measurements showed that approximately 50% of the 5000 kWh/year of domestic hot water consumption was saved by the retrofitted system in south Sweden. Such savings are in agreement with previous estimations and are comparable to the energy savings when using a conventional solar domestic hot water system. The life-cycle cost analysis showed that, according to the assumptions and given climate, the return on investment of the retrofitted system is approximately 17 years, while a conventional system does not reach profitability during its lifetime of 25 years.

    An evaluation of a variety of efficient water heating strategies for an all-electric single family home located in a mixed-humid climate is conducted using numerical modeling. The strategies considered include various combinations of solar thermal, heat pump, and electric resistance water heaters. The numerical model used in the study is first validated against a year of field data obtained on a dual-tank system with a solar thermal preheat tank feeding a heat pump water heater that serves as a backup. Modeling results show that this configuration is the most efficient of the systems studied over the course of a year, with a system coefficient of performance (COPsys) of 2.87. The heat pump water heater alone results in a COPsys of 1.9, while the baseline resistance water heater has a COPsys of 0.95. Impacts on space conditioning are also investigated by considering the extra energy consumption required of the air source heat pump to remove or add heat from the conditioned space by the water heating system. A modified COPsys that incorporates the heat pump energy consumption shows a significant drop in efficiency for the dual tank configuration since the heat pump water heater draws the most heat from the space in the heating season while the high temperatures in the solar storage tank during the cooling season result in an added heat load to the space. Despite this degradation in the COPsys, the combination of the solar thermal preheat tank and the heat pump water heater is the most efficient option even when considering the impacts on space conditioning.

    2016-12-22

    In the Swedish Building Energy, Technical Status and Indoor environment study, a total of 1160 adults from 605 single-family houses answered a questionnaire on respiratory health. Building inspectors investigated the homes and measured temperature, air humidity, air exchange rate, and wood moisture content (in attic and crawl space). Moisture load was calculated as the difference between indoor and outdoor absolute humidity. Totally, 7.3% were smokers, 8.7% had doctor' diagnosed asthma, 11.2% current wheeze, and 9.5% current asthma symptoms. Totally, 50.3% had respiratory infections and 26.0% rhinitis. The mean air exchange rate was 0.36/h, and the mean moisture load 1.70 g/m(3) . Damp foundation (OR=1.79, 95% CI 1.16-2.78) was positively associated while floor constructions with crawl space (OR=0.49, 95% CI 0.29-0.84) was negatively associated with wheeze. Concrete slabs with overlying insulation (OR=2.21, 95% CI 1.24-3.92) and brick façade (OR=1.71, 95% CI 1.07-2.73) were associated with rhinitis. Moisture load was associated with respiratory infections (OR=1.21 per 1 g/m(3) , 95% CI 1.04-1.40) and rhinitis (OR=1.36 per 1 g/m(3) , 95% CI 1.02-1.83). Air exchange rate was associated with current asthma symptoms (OR=0.85 per 0.1/h, 95% CI 0.73-0.99). Living in homes with damp foundation, concrete slabs with overlying insulation, brick façade, low ventilation flow, and high moisture load are risk factors for asthma, rhinitis, and respiratory infections.

    Full Text Available Abstract Background Ophthalmopathy is a common manifestation of Graves’ disease (GD occurring in up to 50% of patients. Mild eye signs are also common in patients with Hashimoto’s thyroiditis. Whilst a genetic predisposition to GD has been demonstrated this is not the case for the ophthalmopathy which often runs a separate course. Objective We determined the prevalences of eye and eyelid signs and positive thyroid and orbital antibody tests in first and second degree relatives from a single family with multiple cases of Graves’ disease, ophthalmopathy and Hashimoto’s thyroiditis. Design The study cohort comprised 16 subjects from the same family, 4 probands namely, 3 with GD and one with Hashimoto’s thyroiditis and hypothyroidism and 12 of their euthyroid first or second degree relatives. We measured antibodies against calsequestrin (CASQ1 and collagen XIII in an enzyme-linked-immunosorbent assays and TSH-Receptor (TSH-R antibodies as i TSH-R binding inhibiting immunoglobulin (TBII and ii thyroid stimulating immunoglobulin (TSI. Eye signs were classified and quantified using the clinical activity score (CAS, NOSPECS classes, Nunery types 1 and 2 and the margin-reflex-distance (MRD as a measure of upper eyelid retraction (UER. Main outcomes Whilst significant ophthalmopathy was uncommon in the relatives, mild eye signs, in particular UER, were demonstrated in about a third of them. The presence of eye signs was moderately, but not significantly, associated with the detection of CASQ1 and collagen XIII antibodies, but not TSH-R antibodies. Conclusion Our study demonstrates a significant prevalence of positive orbital antibody tests and ophthalmopathy in probands with thyroid autoimmunity and their euthyroid relatives, favouring a role of genetic factors in the development of ophthalmopathy in patients with thyroid autoimmunity.

    Microorganisms are known to produce a range of volatile organic compounds, so-called microbial VOC (MVOC). Chamber studies where humans were exposed to MVOC addressed the acute effects of objective and/or subjective signs of mucosal irritation. However, the effect of MVOC on inhabitants due to household exposure is still unclear. The purpose of this epidemiological study was to measure indoor MVOC levels in single family homes and to evaluate the relationship between exposure to them and sick building syndrome (SBS). All inhabitants of the dwellings were given a self-administered questionnaire with standardized questions to assess their symptoms. Air samples were collected and the concentrations of eight selected compounds in indoor air were analyzed by gas chromatography/mass spectrometry - selective ion monitoring mode (GC/MS-SIM). The most frequently detected MVOC was 1-pentanol at a detection rate of 78.6% and geometric mean of 0.60 {mu}g/m{sup 3}. Among 620 participants, 120 (19.4%) reported one or more mucous symptoms; irritation of the eyes, nose, airway, or coughing every week (weekly symptoms), and 30 (4.8%) reported that the symptoms were home-related (home-related symptoms). Weekly symptoms were not associated with any of MVOC, whereas significant associations between home-related mucous symptoms and 1-octen-3-ol (per log{sub 10}-unit: odds ratio (OR) 5.6, 95% confidence interval (CI): 2.1 to 14.8) and 2-pentanol (per log{sub 10}-unit: OR 2.3, 95% CI: 1.0 to 4.9) were obtained after adjustment for gender, age, and smoking. Associations between home-related symptoms and 1-octen-3-ol remained after mutual adjustment. However, concentrations of the selected compounds in indoors were lower than the estimated safety level in animal studies. Thus, the statistically significant association between 1-octen-3-ol may be due to a direct effect of the compounds or the associations may be being associated with other offending compounds. Additional studies are needed

    The vanishing of Tibetan rural lifestyle described in Alai's novel The Vacant Mountain:A Legend is pertinent with the utopian and the dystopian tradition, but divergent from either. In the petty narrative, the matter-of-factly related endeavors of some characters to build an earthly modern paradise are appealing to the implied reader who is familiar with previous works depicting and embellishing Chinese and/or Tibetan farmers'life in the era of socialist construction, or that of modernization. Abandoning kitsch and adhering to a Zen Buddhist's primitive simplicity, the author betrays his own understanding of the rural world undergo-ing modernization. His tremendous success should be attributed to his meticulously selected"objective cor-relatives"as outlets of his primal and ardent emotions.%《空山:机村传说》是一部后顾式、意欲解构乌托邦的小说.在现代化冲击下,乡村生活逐渐消逝的主题在传统意义上的乌托邦与反乌托邦叙事之间徘徊,游移不定.与以往同类题材、同等篇幅的作品不同,这部小说平实地描写人们企图建造人间乐园的努力,具有小叙事的明显特征.作者哀而不怨的叙事功力固然令读者倾倒,作品获得成功的主要原因则应归功于作者对素材的选取以及他本真的情感寄托,这种深厚的情感寄托是以摈弃媚俗,继承传统的禅意、古朴的诗性为基础的.

  16. Conductivity and superconductivity in heavily vacant diamond

    Directory of Open Access Journals (Sweden)

    S A Jafari

    2009-08-01

    Full Text Available   Motivated by the idea of impurity band superconductivity in heavily Boron doped diamond, we investigate the doping of various elements into diamond to address the question, which impurity band can offer a better DOS at the Fermi level. Surprisingly, we find that the vacancy does the best job in producing the largest DOS at the Fermi surface. To investigate the effect of disorder in Anderson localization of the resulting impurity band, we use a simple tight-binding model. Our preliminary study based on the kernel polynomial method shows that the impurity band is already localized at the concentration of 10-3. Around the vacancy concentration of 0.006 the whole spectrum of diamond becomes localized and quantum percolation takes place. Therefore to achieve conducting bands at concentrations on the scale of 5-10 percent, one needs to introduce correlations such as hopping among the vacancies .

    Durability of building envelope is important to new homes that are increasingly built with improved levels of airtightness. It is also important to weatherized homes such that energy savings from retrofit measures, such as air sealing, are persistent. We presented a comparison of air leakage measurements collected in November 2013 through March 2014, with two sets of prior data collected between 2001-2003 from 17 new homes located near Atlanta, GA, and 17 homes near Boise, ID that were weatherized in 2007-2008. The purpose of the comparison is to determine if there are changes to the airtightness of building envelopes over time. The air leakage increased in all but one of the new homes, with a mean increase of about 25%. The weatherized homes also showed an increase in the mean air leakage (12%). We performed a regression analysis to describe the relationship between prior and current measurements in terms of normalized leakage (NL). The best estimate of the aging factor predicts a 15% increase in NL over ten years. Further analysis using ResDB data (LBNL’s Residential Diagnostic Database) showed the expected changes in air leakage if aging were modeled. These results imply that we should examine the causes of increased leakage and methods to avoid them. This increase in leakage with time should be accounted for in long-term population-wide energy savings estimates, such as those used in ratings or energy savings programs.

    Full Text Available Mercury pollution (MeHg up the aquatic food chains in the Amazonian ecosystems has been a major concern in environmental health. Riverside people (ribeirinhos along the Upper Madeira river are heavy fish eaters. Hair is the best biomarker for MeHg exposure. By assuming a constant hair growth rate, it is possible to evaluate a temporal profile of Hg exposure over the recent defined past. In this paper we present the segmental total hair Hg concentrations from a single family from which some of the 10 persons investigated had high hair Hg concentrations (peak of 339 ppm. We also presented the hair MeHg content from 4 out of the 10 family members investigated. There was a wide variation in total hair Hg concentrations (8 to 339 ppm among these individuals, who were mostly sharing their meals; there was also a wide variation in total Hg concentrations in the same individual over time (136 to 274 ppm. Hg speciation showed a mean and standard deviation in the MeHg content of 62% and 6%, respectively. The wide variation in total hair Hg concentration strongly indicated that it is possible to mitigate critical Hg exposure levels by conducting a fish advisory.A poluição por mercúrio orgânico (MeHg das cadeias alimentares aquáticas nos ecossistemas amazônicos constitui tema de relevância na saúde ambiental.

    Full Text Available The increasing prevalence of chronic diseases throughout the world is an undeniable phenomenon; 395,000 deaths occurred in Iran in 2014 and about 76% of them were related to chronic diseases.1 Cancer is one of the chronic diseases that are progressing rapidly. In Iran, cancer is known as the third cause of death. Adult morbidity rate of cancer in different regions of Iran is estimated 48-112 cases per million people among the females and 51-144 cases per million people among the males.2 Also, mortality rate related to cancer was about 53500 people in 2014.3 In fact, 13% of all deaths related to chronic diseases are caused by cancer1 and the majority of cancer patients expire in the intensive care units (ICU, whereas bed occupancy of ICUs is in crises, being about 100% in Iran. For each ICU bed, 4 people are applicants. In this situation, firstly, a number of patients do not have access to the ICU beds, and secondly, because of the need to ICU beds, the admitted patients in ICU wards are discharged earlier than the standard time for each disease. According to the head of the Intensive Care association, the shortage of ICU beds is about ten thousand in Iran, whereas setting up each ICU bed requires a high cost.4 In the current condition, due to the high cost and shortage of nurses in Iran, setting up of ICU beds is a challenge for the health system. WHO introduced home-based palliative care to improve the quality of life, quality of care, quality of death and patient satisfaction; decrease burnout in staffing and mortality in hospitals; reduce the cost, accept end of life as live days; neither accelerate death nor prolong life; consider all dimensions of human; help the patients to be active until the time of death; help the patient’s family to cope with the disease and loss of patient; and release the beds in hospitals.5 Although hospital beds are considered for healing the patients not a hospice for them, the majority of cancer patients die in the hospital and on the ICU beds, and to the last moments of life, they receive specialized cure, and occupy ICU beds, while the specialists are aware that this treatment is unfruitful, and this reality is supported by science. In the developed countries, the gap between death and specific cures is considered as an indicator of the quality of physician services and more length of time will be better indicator for physician services, while cancer patients in health system of Iran receive specific treatment and chemotherapy even to moment of death. To consider countless benefits of home care6 and the patients’ desire to receive services at home,7 if we can provide the conditions that at least 20% of end stage cancer patients in receive home based palliative care, 1000 deaths will occur at home yearly, and 1000 ICU beds will be released for use for other patients with better prognosis for survival. Therefore, health system authorities in Iran should considered home-based palliative care of cancer patients as a priority.

  20. Experimental Evaluation of Ventilation Systems in a Single-Family Dwelling

    CERN Document Server

    Koffi, Juslin; Akoua, Jean-Jacques

    2010-01-01

    The French regulation on residential building ventilation relies on an overall and continuous air renewal. The fresh air should enter the building through the "habitable rooms" while the polluted air is extracted in the service rooms. In this way, internal air is drained from the lowest polluted rooms to the highest polluted ones. However, internal pressure equilibrium and air movements in buildings result from the combined effects ventilation system and parameters such as wind, temperature difference or doors opening. This paper aims to analyse the influence of these parameters on pollutant transfer within buildings. In so doing, experiments are carried out using tracer gas release for representing pollution sources in an experimental house. Mechanical exhaust, balanced and natural ventilation systems are thus tested. Results show the followings: - For all cases, internal doors' opening causes the most important pollutant spread. - When doors are closed, the best performances are obtained with balanced venti...

  1. Analysis of advanced conceptual designs for single-family-sized absorption chillers. Semi-annual report

    1978-04-05

    The objective of the research program is to develop and analyze new concepts for absorption cycles to improve the performance or reduce the cost (or both) of a 3-ton absorption chiller that can be used with solar-collected heat. New refrigerant-absorbent pairs, additives to currently used refrigerant-absorbent pairs, and modifications to the cycle are being investigated. For the initial analyses the use of a fluid at 160 to 230/sup 0/F from a solar collector as a heating source is assumed. In the initial analyses the chiller is to provide chilled water at 45/sup 0/F at full load; alternatively, if a new refrigerant-absorbent pair appears to be amenable for direct cooling of the occupied space, the temperature of the evaporator is to be 45/sup 0/F. Both water cooling and air cooling of the absorber and the condenser are being studied. The use of ambient air at 95/sup 0/F dry bulb and 75/sup 0/F wet bulb temperatures is assumed. With the water-cooled cycles, the initial and operating costs of a properly sized cooling tower will be included. The research consists of five principal tasks: (a) acquisition of information for analysis, (b) definition of criteria for selection of promising refrigerant-absorbent pairs, additives for currently used pairs, or cycle modifications, (c) preparation and analysis of conceptual designs, (d) comparison and selection of the promising new systems that warrant further study, and (e) recommendations for further research for each promising new system. Progress on each of these tasks is described. (WHK)

    Food waste prevention remains the first priority in the European Waste Framework Directive, which aimed to halve the amount of food wasted within the EU Member States by 2025. Thus, reliable data on food waste composition and quantity are crucial for assessing the current food waste situation...... and determine potential improvements. In Denmark, although many sorting campaigns involving household waste has been conducted, little attention has been placed on food waste. Comparison of recent studies made for examples in Austria, and the UK suggests that quantity and material composition of food waste vary...... significantly among the studies and differ from one country to another. Here, we provide a consistent methodology for characterization of household food waste, so that data comparability and source information are ensured. In this study, residual household waste was sampled and manually sorted from more than...

  3. Variable myopathic presentation in a single family with novel skeletal RYR1 mutation.

    Directory of Open Access Journals (Sweden)

    Ruben Attali

    Full Text Available We describe an autosomal recessive heterogeneous congenital myopathy in a large consanguineous family. The disease is characterized by variable severity, progressive course in 3 of 4 patients, myopathic face without ophthalmoplegia and proximal muscle weakness. Absence of cores was noted in all patients. Genome wide linkage analysis revealed a single locus on chromosome 19q13 with Zmax = 3.86 at θ = 0.0 and homozygosity of the polymorphic markers at this locus in patients. Direct sequencing of the main candidate gene within the candidate region, RYR1, was performed. A novel homozygous A to G nucleotide substitution (p.Y3016C within exon 60 of the RYR1 gene was found in patients. ARMS PCR was used to screen for the mutation in all available family members and in an additional 150 healthy individuals. This procedure confirmed sequence analysis and did not reveal the A to G mutation (p.Y3016C in 300 chromosomes from healthy individuals. Functional analysis on EBV immortalized cell lines showed no effect of the mutation on RyR1 pharmacological activation or the content of intracellular Ca(2+ stores. Western blot analysis demonstrated a significant reduction of the RyR1 protein in the patient's muscle concomitant with a reduction of the DHPRα1.1 protein. This novel mutation resulting in RyR1 protein decrease causes heterogeneous clinical presentation, including slow progression course and absence of centrally localized cores on muscle biopsy. We suggest that RYR1 related myopathy should be considered in a wide variety of clinical and pathological presentation in childhood myopathies.

    Lee, Taekhee; Grinshpun, Sergey A.; Martuzevicius, Dainius; Adhikari, Atin; Crawford, Carlos M.; Reponen, Tiina

    In this study, the culturability of indoor and outdoor airborne fungi was determined through long-term sampling (24-h) using a Button Personal Inhalable Aerosol Sampler. The air samples were collected during three seasons in six Cincinnati area homes that were free from moisture damage or visible mold. Cultivation and total microscopic enumeration methods were employed for the sample analysis. The geometric means of indoor and outdoor culturable fungal concentrations were 88 and 102 colony-forming units (CFU) m -3, respectively, with a geometric mean of the I/ O ratio equal to 0.66. Overall, 26 genera of culturable fungi were recovered from the indoor and outdoor samples. For total fungal spores, the indoor and outdoor geometric means were 211 and 605 spores m -3, respectively, with a geometric mean of I/ O ratio equal to 0.32. The identification revealed 37 fungal genera from indoor and outdoor samples based on the total spore analysis. Indoor and outdoor concentrations of culturable and total fungal spores showed significant correlations ( r=0.655, pvalue of culturability (38% and 33% for indoor and outdoor, respectively) followed by Aspergillus/Penicillium (9% and 2%) among predominant genera of fungi. Increased culturability of fungi inside the homes may have important implications because of the potential increase in the release of allergens from viable spores and pathogenicity of viable fungi on immunocompromised individuals.

  14. Method for planning extensive energy renovation of detached single-family houses

    . This will take time, so both areas must be considered already now, but it will be beneficial to work on reducing the consumption before the sustainable energy supply is fully developed, so that we can avoid expensive over-production. Some 30% of the total energy consumption in Denmark takes place in households...... that the use of this approach produced a better renovation with a larger energy saving. The initial evaluation helped the house owners identify a maintenance backlog, and the use of an independent advisor helped ensure quality throughout the process. Renovations are too often carried out for just one purpose......: maintenance, to update functions or to reduce energy consumption. But a lot can be gained by combining these efforts, which can reduce expenses for planning and execution and avoid doing things twice. Research for this thesis demonstrated this approach by carrying out a renovation based on maintenance...

  15. Chaos and robustness in a single family of genetic oscillatory networks.

    Directory of Open Access Journals (Sweden)

    Daniel Fu

    Full Text Available Genetic oscillatory networks can be mathematically modeled with delay differential equations (DDEs. Interpreting genetic networks with DDEs gives a more intuitive understanding from a biological standpoint. However, it presents a problem mathematically, for DDEs are by construction infinitely-dimensional and thus cannot be analyzed using methods common for systems of ordinary differential equations (ODEs. In our study, we address this problem by developing a method for reducing infinitely-dimensional DDEs to two- and three-dimensional systems of ODEs. We find that the three-dimensional reductions provide qualitative improvements over the two-dimensional reductions. We find that the reducibility of a DDE corresponds to its robustness. For non-robust DDEs that exhibit high-dimensional dynamics, we calculate analytic dimension lines to predict the dependence of the DDEs' correlation dimension on parameters. From these lines, we deduce that the correlation dimension of non-robust DDEs grows linearly with the delay. On the other hand, for robust DDEs, we find that the period of oscillation grows linearly with delay. We find that DDEs with exclusively negative feedback are robust, whereas DDEs with feedback that changes its sign are not robust. We find that non-saturable degradation damps oscillations and narrows the range of parameter values for which oscillations exist. Finally, we deduce that natural genetic oscillators with highly-regular periods likely have solely negative feedback.

    Science.gov (United States)

    1982-04-01

    A house with approximately 1360 square feet of conditioned space heated by a direct gain system with manually operated insulated curtains is discussed. Solar heating is augmented by electric resistance heating, and a wood burning stove may be installed. Sunlight is admitted through both south facing windows and through clerestory collector panels and is absorbed and stored as heat in a concrete floor and wall. Heat is then distributed by natural convection and radiation. Temperature regulation is assisted by Earth beams. Three modes of operation are described: collector-to-storage, storage-to-space heating, and passive space cooling, which is accomplished by shading, movable insulation, and ventilation. The instrumentation for the National Solar Data Network is described. The solar energy portion of the construction costs is estimated.

  20. Measurement-Based Evaluation of Installed Filtration System Performance in Single-Family Homes

    Chan, Wanyu Rengie; Singer, Brett C.

    2014-04-03

    This guide discusses important study design issues to consider when conducting an on-site evaluation of filtration system performance. The two most important dichotomies to consider in developing a study protocol are (1) whether systems are being evaluated in occupied or unoccupied homes and (2) whether different systems are being compared in the same homes or if the comparison is between systems installed in different homes. This document provides perspective and recommendations about a suite of implementation issues including the choice of particle measurement devices, selection of sampling locations, ways to control and/or monitor factors and processes that can impact particle concentrations, and data analysis approaches.

    Durability of the building envelope is important to new homes that are increasingly built with improved levels of airtightness. It is also important to weatherized homes such that energy savings from retrofit measures, such as air sealing, are persistent. This paper presents a comparison of air leakage measurements collected in November 2013 through March 2014, with two sets of prior data collected between 2001-2003 from 17 new homes located near Atlanta, GA, and 17 homes near Boise, ID that were weatherized in 2007-2008. The purpose of the comparison is to determine if there are changes to the airtightness of building envelopes over time. The air leakage increased in all but one of the new homes, with a mean increase of about 25%. A regression analysis was performed to describe the relationship between prior and current measurements in terms of normalized leakage (NL).

    2014-05-01

    Full Text Available In the formulation of hedonic models, in addition to locational factors and building structures which affect the house prices, the generation of the omitted variable bias is thought to occur in cases when local environmental variables and the individual characteristics of house buyers are not taken into consideration. However, since it is difficult to obtain local environmental information in a small neighborhood unit and to observe individual characteristics of house buyers, these variables have not been sufficiently considered in previous studies. We demonstrated that non-negligible levels of omitted variable bias are generated if these variables are not considered.

  5. Demand controlled ventilation in single-family homes; Behovstyret ventilation til enfamiliehuse

    Energy Technology Data Exchange (ETDEWEB)

    Rammer Nielsen, T.; Drivsholm, C.; Rudolph Hansen, M.P.; Kragh, J.

    2009-12-15

    This project investigated two different control strategies: A simple and cheap strategy and an advanced and expensive strategy: 1. Simple control: The ventilation rate is varied only on the whole building level giving an average ventilation rate of either 0.1 l/(s m{sup 2}) or 0.35 l/(s m{sup 2}). The air change rate is controlled by sensors in the air handling unit measuring relative humidity, temperature and CO{sub 2}. The control is based on the CO{sub 2}-concentration and absolute humidity in the supply air and exhaust air. A fixed set point for the difference in CO{sub 2}-concentration between the exhaust and supply is used to decide if the ventilation rate is low or high. As supplement to the CO{sub 2} control the difference in absolute humidity between exhaust and supply is used to assure that the ventilation remain at the high level if there is a high level of humidity in the house. 2. Advanced control: The air change rate is varied dynamically for all living rooms giving an average air change for the house between 0.1 l/(s m{sup 2}) and 0.35 l/(s m{sup 2}). The air change rate in the living rooms is controlled by CO{sub 2}-sensors in each room and dampers in the room supply duct. Relative humidity is measured in the rooms with high moisture production to ensure that the highest air exchange is activated if the relative humidity in one of these rooms is too high. Even though the two strategies have been implemented and tested for a long period of time, only the simple control can be recommended. The simple control ensures that the air quality is almost the same as if the house was ventilated constantly at the high ventilation rate. Also the simple control only requires two CO{sub 2} sensors, two relative humidity sensors and two temperature sensors in the air handling unit. These sensors should be checked from time to time e.g. when filters are exchanged. The simple control is today used in meeting rooms, office rooms and daycare facilities in a modified form. The advanced control has some potential advantages compared to the simple control. This is mainly the possibility to achieve better use of the air by supplying it where it is needed. To achieve energy savings compared to the simple control it is necessary to also reduce the air change rate during occupancy. This will lead to a discussion on whether this control results in reduced air quality and whether this reduction is acceptable. There is at present time not enough knowledge on how the indoor climate affects health of the occupants to recommend that the air change rate can be reduced during occupancy. More results are needed from laboratory and field experiments before the advanced control can be recommended. (LN)

    While the reaction of [PW(11)O(39)](7-) with first row transition-metal ions M(n+) under usual bench conditions only leads to monosubstituted {PW(11)O(39)M(H(2)O)} anions, we have shown that the use of this precursor under hydrothermal conditions allows the isolation of a family of novel polynuclear discrete magnetic polyoxometalates (POMs). The hybrid asymmetric [Fe(II)(bpy)(3)][PW(11)O(39)Fe(2) (III)(OH)(bpy)(2)]12 H(2)O (bpy=bipyridine) complex (1) contains the dinuclear {Fe(micro-O(W))(micro-OH)Fe} core in which one iron atom is coordinated to a monovacant POM, while the other is coordinated to two bipyridine ligands. Magnetic measurements indicate that the Fe(III) centers in complex 1 are weakly antiferromagnetically coupled (J=-11.2 cm(-1), H=-JS(1)S(2)) compared to other {Fe(micro-O)(micro-OH)Fe} systems. This is due to the long distances between the iron center embedded in the POM and the oxygen atom of the POM bridging the two magnetic centers, but also, as shown by DFT calculations, to the important mixing of bridging oxygen orbitals with orbitals of the POM tungsten atoms. The complexes [Hdmbpy](2)[Fe(II)(dmbpy)(3)](2)[(PW(11)O(39))(2)Fe(4) (III)O(2)(dmbpy)(4)]14 H(2)O (2) (dmbpy=5,5'-dimethyl-2,2'-bipyridine) and H(2)[Fe(II)(dmbpy)(3)](2)[(PW(11)O(39))(2)Fe(4) (III)O(2)(dmbpy)(4)]10 H(2)O (3) represent the first butterfly-like POM complexes. In these species, a tetranuclear Fe(III) complex is sandwiched between two lacunary polyoxotungstates that are pentacoordinated to two Fe(III) cations, the remaining paramagnetic centers each being coordinated to two dmbpy ligands. The best fit of the chi(M)T=f(T) curve leads to J(wb)=-59.6 cm(-1) and J(bb)=-10.2 cm(-1) (H=-J(wb)(S(1)S(2)+S(1)S(2*)+S(1*)S(2)+S(1*)S(2*))-J(bb)(S(2)S(2*))). While the J(bb) value is within the range of related exchange parameters previously reported for non-POM butterfly systems, the J(wb) constant is significantly lower. As for complex 1, this can be justified considering Fe(w)--O distances. Finally, in the absence of a coordinating ligand, the dimeric complex [N(CH(3))(4)](10)[(PW(11)O(39)Fe(III))(2)O]12 H(2)O (4) has been isolated. In this complex, the two single oxo-bridged Fe(III) centers are very strongly antiferromagnetically coupled (J=-211.7 cm(-1), H=-JS(1)S(2)). The electrochemical behavior of compound 1 both in dimethyl sulfoxide (DMSO) and in the solid state is also presented, while the electrochemical properties of complex 2, which is insoluble in common solvents, have been studied in the solid state.

    This study was intended to characterize the perceived risks of urban agriculture by residents of four low-income neighborhoods in which the potential exists for further urban agriculture development and to provide data to support whether any chemical hazards and foodborne pathogens as potential food safety hazards were present. Sixty-seven residents participated in focus groups related to environmental health, food security, and urban gardening. In addition, soils from six locations were tested. Residents expressed interest in the development of urban gardens to improve access to healthy, fresh produce, but they had concerns about soil quality. Soils were contaminated with lead (Pb), zinc, cadmium (Cd), and copper, but not arsenic or chromium. Results from our study suggest paint was the main source of soil contamination. Detectable polyaromatic hydrocarbon (PAH) levels in urban soils were well below levels of concern. These urban soils will require further management to reduce Pb and possibly Cd bioavailability to decrease the potential for uptake into food crops. Although the number of locations in this study is limited, results suggest lower levels of soil contaminants at well-established gardens. Soil tillage associated with long-term gardening could have diluted the soil metal contaminants by mixing the contaminants with clean soil. Also, lower PAH levels in long-term gardening could be due to enhanced microbial activity and PAH degradation, dilution, or both due to mixing, similar to metals. No foodborne pathogen targets were detected by PCR from any of the soils. Residents expressed the need for clearness regarding soil quality and gardening practices in their neighborhoods to consume food grown in these urban areas. Results from this study suggest long-term gardening has the potential to reduce soil contaminants and their potential threat to food quality and human health and to improve access to fresh produce in low-income urban communities.

    The current state of Deep Energy Retrofit (DER) performance in the U.S. has been assessed in 116 homes in the United States, using actual and simulated data gathered from the available domestic literature. Substantial airtightness reductions averaging 63% (n=48) were reported (two- to three-times more than in conventional retrofits), with average post-retrofit airtightness of 4.7 Air Changes per House at 50 Pascal (ACH50) (n=94). Yet, mechanical ventilation was not installed consistently. In order to avoid indoor air quality (IAQ) issues, all future DERs should comply with ASHRAE 62.2-2013 requirements or equivalent. Projects generally achieved good energy results, with average annual net-site and net-source energy savings of 47%±20% and 45%±24% (n=57 and n=35), respectively, and carbon emission reductions of 47%±22% (n=23). Net-energy reductions did not vary reliably with house age, airtightness, or reported project costs, but pre-retrofit energy usage was correlated with total reductions (MMBtu).

    The current state of Deep Energy Retrofit (DER) performance in the U.S. has been assessed in 116 homes in the United States (US), using actual and simulated data gathered from the available domestic literature. Substantial airtightness reductions averaging 63% (n=48) were reported (two- to three-times more than in conventional retrofits), with average post-retrofit airtightness of 4.7 Air Changes per House at 50 Pascal (ACH50) (n=94). Yet, mechanical ventilation was not installed consistently. In order to avoid indoor air quality (IAQ) issues, all future DERs should comply with ASHRAE 62.2-2013 requirements or equivalent. Projects generally achieved good energy results, with average annual net-site and net-source energy savings of 47%±20% and 45%±24% (n=57 and n=35), respectively, and carbon emission reductions of 47%±22% (n=23). Net-energy reductions did not vary reliably with house age, airtightness, or reported project costs, but pre-retrofit energy usage was correlated with total reductions (MMBtu). Annual energy costs were reduced $1,283±$804 (n=31), from a pre-retrofit average of $2,738±$1,065 to $1,588±$561 post-retrofit (n=25 and n=39). The average reported incremental project cost was $40,420±$30,358 (n=59). When financed on a 30-year term, the median change in net-homeownership cost was only $1.00 per month, ranging from $149 in savings to an increase of $212 (mean=$15.67±$87.74; n=28), and almost half of the projects resulted in reductions in net-cost. The economic value of a DER may be much greater than is suggested by these net-costs, because DERs entail substantial non-energy benefits (NEBs), and retrofit measures may add value to a home at resale similarly to general remodeling, PV panel installation, and green/energy efficient home labels. These results provide estimates of the potential of DERs to address energy use in existing homes across climate zones that can be used in future estimates of the technical potential to reduce household energy use and greenhouse gas emissions through DERs.

  20. 1996-2004 Trends in the Single-Family Housing Market: Spatial Analysis of the Residential Sector

    This report provides a detailed geographic analysis of two specific topics affecting the residential sector. First, we performed an analysis of new construction market trends using annual building permit data. We report summarized tables and national maps to help illustrate market conditions. Second, we performed a detailed geographic analysis of the housing finance market. We analyzed mortgage application data to provide citable statistics and detailed geographic summarization of the residential housing picture in the US for each year in the 1996-2004 period. The databases were linked to geographic information system tools to provide various map series detailing the results geographically. Looking at these results geographically may suggest potential new markets for TD programs addressing the residential sector that have not been considered previously. For example, we show which lenders affect which regions and which income or mortgage product classes. These results also highlight the issue of housing affordability. Energy efficiency R&D programs focused on developing new technology for the residential sector must be conscious of the costs of products resulting from research that will eventually impact the home owner or new home buyer. Results indicate that home values as a proportion of median family income in Building America communities are closely aligned with the national average of home value as a proportion of median income. Other key findings: • The share of home building and home buying activity continues to rise steadily in the Hot-Dry and Hot-Humid climate zones, while the Mixed-Humid and Cold climate zone shares continue to decline. Other zones remain relatively stable in terms of share of housing activity. • The proportion of home buyers having three times the median family income for their geography has been steadily increasing during the study period. • Growth in the Hispanic/Latino population and to a lesser degree in the Asian population has translated into proportional increases in share of home purchasing by both groups. White home buyers continue to decline as a proportion all home buyers. • Low interest rate climate resulted in lenders moving back to conventional financing, as opposed to government-backed financing, for cases that would be harder to financing in higher rate environments. Government loan products are one mechanism for affecting energy efficiency gains in the residential sector. • The rate environment and concurrent deregulation of the finance industry resulted unprecedented merger and acquisition activity among financial institutions during the study period. This study conducted a thorough accounting of this merger activity to inform the market share analysis provided. • The home finance industry quartiles feature 5 lenders making up the first quartile of home purchase loans, 18 lenders making up the second quartile, 111 lenders making up the third quartile, and the remaining nearly 8,000 lenders make up the fourth quartile.

    Efforts have been made in Brazil to improve the thermal performance of low-cost buildings. Since 1997 studies on low-cost housing have been developed by Nucleo Orientado para a Inovacao da Edificacao, the construction sector of the Engineering College of the Rio Grande do Sul University, Brazil. In 2000 a prototype of a low-cost house was built on the university campus. This prototype has undergone several evaluations in an attempt to assess its thermal and environmental performance, like: energy consumption, rainwater harvesting, use of sustainably managed wood for window frames and doors, besides a detailed accounting of overall costs. The thermal performance of the house was monitored, by recording outdoor and indoor air temperatures and relative humidity, over the period of whole year. A brief appraisal of such results, as well as the annual heating and cooling degree-hours are presented. Daily swings in outdoor are a common climatic event in Porto Alegre and the building response to daily temperature swings, greater than 10 K, and hot and cold spells are presented. The results show that the thermal performance of the prototype is fairly satisfactory, considering the limitations of a low-cost house, when artificial heating and cooling is not affordable.

Previous reports have documented positive influence of the dNICU in cardiorespiratory status, physiologic stability, and weight gain of the infants. The objective of this study was to explore selected nutrition outcomes of infants in the dNICU versus tNICU.Method: A prospective cohort study was conducted on infants with birth weight of 1500 g or less cared for in dNICU (n = 42 or tNICU (n = 31. Differences between days to reach full parenteral nutrition, full enteral nutrition, or full bottling were determined using analysis of covariance controlling for gestational age, birth weight, and clinical risk index for babies (CRIB acuity score.Results: There were no differences between the two groups in days to reach full parenteral and bottle feeding. The infants in the dNICU took fewer days to reach full enteral nutrition (20.8 days, 95% confidence intervals [CI]: 17, 24.6 (dNICU vs 23.3 days, 95% CI: 17.1, 29.6 (tNICU, P = 0.04 than those in the tNICU.Conclusions: Although the two groups of infants only differed in the days to reach full enteral feeding, it is important to remember that the lack of difference may be clinically significant. Clinically, the infants in the dNICU were younger (gestational age and sicker (CRIB acuity score than the infants in the tNICU. Consequently, the results of this study support the change to dNICU, as the private room model provides a supportive environment for growth as evidenced by similar nutritional outcome measures.

    In 2011, Rural Development, Inc. (RDI) completed the construction of Wisdom Way Solar Village (WWSV), which is a development of 20 very efficient homes in Greenfield, Massachusetts. The homes feature R-40 walls, triple-pane windows, R-50 attic insulation, and airtight construction. All homes also have photovoltaic (PV) systems and solar domestic hot water (SDHW) systems. Auxiliary water heating is provided by tankless gas water heaters. With the SDHW systems, RDI hoped to eliminate most of the need for gas for water heating and get the homes closer to zero energy.

    Full Text Available Screens and brains are peculiar processual frames and/or framing devices. This essay which is part of a larger project intends to demonstrate the value of neurocinematic frames for both cultural studies and scientific considerations. The fusion of theories of cinema and neuroscience needs a media theory that is informed by the affective turn in the humanities. The delicacy of neurocinematic frames becomes visible once they get torn and ruined by diverse depressed, entropic, and disaffected minds as trains of thought that seem to disperse and combust. These phenomena give the project traction and focus. A certain kind of film theory might challenge traditional scholarly concepts of the mind but leads towards a fertile enunciation of the volatile and fragile (en-trails of thought itself.It is a film theory that includes autopoietic psychological systems in the sense of Humberto Maturana and others which was formulated first and foremost by Gilles Deleuze in his two monographs on movement-images and time-images (2006, 2009.

    Currently available photovoltaic (PV) battery systems make it possible to increase the proportion of self-consumed as well as of self-produced electricity, in other words: to raise the degree of energy self-sufficiency. The next step towards greater private electricity autarky, surpassing the high rates of private consumption and self-production already achievable today, could come from PV hybrid systems. However this still presupposes the presence of a base-load capable generator for covering the residual load. But is electricity self-sufficiency economically desirable at all? This article undertakes a simulation-based analysis of the economic efficiency of a PV hybrid system consisting of a PV plant, a battery and a diesel generator.

    We have identified three mutations associated with transferase-deficiency galactosemia in a three-generation family including affected members in two generations and have modeled all three mutations in a yeast-expression system. A sequence of pedigree, biochemical, and molecular analyses of the galactose-1-phosphate uridyltransferase (GALT) enzyme and genetic locus in both affected and carrier individuals revealed three distinct base substitutions in this family, two (Q188R and S135L) that had been reported previously and one (V151A) that was novel. Biochemical analyses of red-blood-cell lysates from the relevant family members suggested that each of these mutations was associated with dramatic impairment of GALT activity in these cells. While this observation was consistent with our previous findings concerning the Q188R mutation expressed both in humans and in a yeast-model system, it was at odds with a report by Reichardt and colleagues, indicating that in their COS cell-expression system the S135L substitution behaved as a neutral polymorphism. To address this apparent paradox, as well as to investigate the functional significance of the newly identified V151A substitution, all three mutations were recreated by site-directed mutagenesis of the otherwise wild-type human GALT sequence and were expressed both individually and in the appropriate allelic combinations in a GALT-deficient strain of the yeast Saccharomyces cerevisiae. The results of these yeast-modeling studies were fully consistent with the patient data, leading us to conclude that, at least within the context of the cell types studied, in the homozygous state Q188R is a mutation that eliminates GALT activity, and S135L and V151A are both mutations that impair GALT activity to <6% of wild-type values. 22 refs., 5 figs.

    Galactosemia is an autosomal recessive disorder of galactose metabolism. In the very first instance of its kind from India, the authors report the presence of three different galatose-1-phosphate uridyl transferase (GALT) gene mutations, associated with galactosemia, in a single Indian family. One of the three mutations, S307X, is a novel mutation (GenBank Accession number GQ355273) and is of nonsense nature causing the truncation of the GALT protein resulting in the decreased enzyme activity. The authors have also emphasized the importance of introduction of new born screening program for galactosemia and its genetic analysis in select settings across the country.

    Full Text Available Abstract Background Tuberous sclerosis complex (TSC is an autosomal dominant disorder characterised by seizures, mental retardation and the development of hamartomas in a variety of organs and tissues. The disease is caused by mutations in either the TSC1 gene on chromosome 9q34, or the TSC2 gene on chromosome 16p13.3. The TSC1 and TSC2 gene products, TSC1 and TSC2, interact to form a protein complex that inhibits signal transduction to the downstream effectors of the mammalian target of rapamycin (mTOR. Methods We have used a combination of different assays to characterise the effects of a number of pathogenic TSC2 amino acid substitutions on TSC1–TSC2 complex formation and mTOR signalling. Results We used these assays to compare the effects of 9 different TSC2 variants (S132C, F143L, A196T, C244R, Y598H, I820del, T993M, L1511H and R1772C identified in individuals with symptoms of TSC from 4 different families. In each case we were able to identify the pathogenic mutation. Conclusion Functional characterisation of TSC2 variants can help identify pathogenic changes in individuals with TSC, and assist in the diagnosis and genetic counselling of the index cases and/or other family members.

  1. Field Test Evaluation of Conservation Retrofits of Low-Income, Single-Family Buildings in Wisconsin: Blower-Door-Directed Infiltration Reduction Procedure, Field Test Implementation and Results

    Energy Technology Data Exchange (ETDEWEB)

    Gettings, M.B.

    2001-05-21

    A blower-door-directed infiltration retrofit procedure was field tested on 18 homes in south central Wisconsin. The procedure, developed by the Wisconsin Energy Conservation Corporation, includes recommended retrofit techniques as well as criteria for estimating the amount of cost-effective work to be performed on a house. A recommended expenditure level and target air leakage reduction, in air changes per hour at 50 Pascal (ACH50), are determined from the initial leakage rate measured. The procedure produced an average 16% reduction in air leakage rate. For the 7 houses recommended for retrofit, 89% of the targeted reductions were accomplished with 76% of the recommended expenditures. The average cost of retrofits per house was reduced by a factor of four compared with previous programs. The average payback period for recommended retrofits was 4.4 years, based on predicted energy savings computed from achieved air leakage reductions. Although exceptions occurred, the procedure's 8 ACH50 minimum initial leakage rate for advising retrofits to be performed appeared a good choice, based on cost-effective air leakage reduction. Houses with initial rates of 7 ACH50 or below consistently required substantially higher costs to achieve significant air leakage reductions. No statistically significant average annual energy savings was detected as a result of the infiltration retrofits. Average measured savings were -27 therm per year, indicating an increase in energy use, with a 90% confidence interval of 36 therm. Measured savings for individual houses varied widely in both positive and negative directions, indicating that factors not considered affected the results. Large individual confidence intervals indicate a need to increase the accuracy of such measurements as well as understand the factors which may cause such disparity. Recommendations for the procedure include more extensive training of retrofit crews, checks for minimum air exchange rates to insure air quality, and addition of the basic cost of determining the initial leakage rate to the recommended expenditure level. Recommendations for the field test of the procedure include increasing the number of houses in the sample, more timely examination of metered data to detect anomalies, and the monitoring of indoor air temperature. Though not appropriate in a field test of a procedure, further investigation into the effects of air leakage rate reductions on heating loads needs to be performed.

    目的 探讨铊中毒患者的临床表现和治疗方法.方法 对2008年5月就诊于我院的6例确诊急慢性铊中毒患者的临床表现和治疗经过进行回顾性分析.结果 6例患者中男性4例,女 性2例,年龄12~50岁,来自同一家庭(为一对姐妹和各自的丈夫及儿子).其中5例患者[3例为急性中毒,2例为慢性中毒(半年内第2次中毒)]均以多发性周围神经炎起病,表现为肢体末端麻木、疼痛、感觉异常,伴或不伴消化道症状;1例为12岁男性患儿,尿铊浓度超过中毒量,却无相关的临床表现.治疗上采用补钾、利尿、导泻、口服普鲁士蓝(氰化铁合亚铁)、肌注二巯基丙磺酸钠等措施,其中2例同时采用血液灌流治疗.最后2例患者好转出院,2例转专科医院进一步治疗,另2例慢性铊中毒患者病情进展迅速,最后昏迷,因多器官功能衰竭而死亡.结论 铊中毒临床表现主要包括多发性周围神经炎、胃肠道症状和皮肤损害,对于出现类似症状的患者应高度警惕铊中毒的可能性,避免漏诊、误诊.治疗上除传统的普鲁士蓝效果肯定外,血液灌流亦可能是疗效更加肯定的措施.%Objective To further investigate clinical manifestations and management for thallium poisoning. Methods Clinical data of 6 patients who were hospitalized in Union Hospital of Tongji Medical College in May 2008 with diagnosis of acute or chronic thallium poisoning,were retrospectively analyzed.Results Six patients (4 male and 2 female) ,aged from 12 to 50,came from one family (two sisters with their husbands and sons). Five of them (3 acute and 2 chronic,for the second time in half a year,thallium poisoning) initiated with peripheral neuritis,represented with severe burning pain,numbness,paresthesia in the lower limbs,accompanied with or without gastrointestinal symptoms. A 12 year-old boy with obviously elevated urinary thallium concentration was asymptomatic. Blood and urinary thallium concentrations of the patients were determined by atomic absorption spectrophotometry and were all significantly elevated.Treatment was initiated using potassium supplementation,diuresis,oral laxatives,Prussian blue and intramuscular injection of dimercaptopropansulfonate sodium.Meanwhile two of them were treated with hemoperfusion. Finally,two of them recovered,another two were transferred to a specialized hospital for continuous treatment,and the rest two deteriorated rapidly with occurrence of unconsciousness and died of multiple organ failure. Conclusions The main clinical manifestations of thallium poisoning are multiple peripheral neuritis,gastrointestinal symptoms and dermatological changes. In order to avoid missed diagnosis and misdiagnosis,a high suspicion should be arose for thallium poisoning when a patient suffering from the above symptoms.Prussian blue was considered traditionally as an effective therapeutic strategy for the condition,and hemoperfusion may be a more effective treatment for acute thallium poisoning.

    In view of increasing electricity costs and the remuneration by the EEG, systematic measures to enhance the own consumption of photovoltaic power increasingly come to the fore of public discussion - in spite of recent reductions of the remunerations by the EEG. In order to increase own consumption and the rate of self-sufficiency, the so-called own coverage, the first commercial battery storage systems are available. The Research Center for Energy Economics (Forschungsstelle fuer Energiewirtschaft e.V., FfE) developed a model that simulates a decentralized domestic power supply by a photovoltaic system, battery and connection to the grid. This simulation model enables the determination of the rate of own consumption and own coverage for different constellations of the power supply of a household. (orig.)

    Full Text Available With the decrease in the demand for large-scale apartments as a result of an aging society and a decrease in population, there has been an increase in vacant houses due to a supply that exceeds the projected demands. As a method of urban regeneration in rural areas and activation of citizen communities, the utilization of vacant houses has become one of the ways to promote a new lifestyle, active movement for citizen participation, and business model for long-term revitalization. This study aims to uncover and examine the major causes and factors behind the upswing in vacant houses. We investigated the current state of vacant houses, the recent policies concerning them, and the types of vacant houses in Korea’s Gyeonggi province. We then categorized and analyzed the causes of houses being vacant, their types, and the methods of utilizing them under different local conditions in order to understand the efficient processes and strategies for their utilization. The results showed that an excess of building construction (especially recent construction permits, the number of recipients of the national basic livelihood scheme, and the number of elderly people showed the strongest correlation with vacant houses.

    2011-10-12

    It is demonstrated that, on a silver oxide surface, direct formation of ethylene oxide (EO) through the reaction between gas phase ethylene and surface oxygen is possible. The direct reaction channel produces EO selectively without competing with acetaldehyde (AA) formation. The oxometallacycle (OMC) forms on an oxygen vacant surface and reduces EO selectivity. Cl adsorption removes these surface vacant sites and hence prevents the formation of the OMC intermediate.

    We study a directed flipping process that underlies the performance of the random edge simplex algorithm. In this stochastic process, which takes place on a one-dimensional lattice whose sites may be either occupied or vacant, occupied sites become vacant at a constant rate and simultaneously cause all sites to the right to change their state. This random process exhibits rich phenomenology. First, there is a front, defined by the position of the leftmost occupied site, that propagates at a nontrivial velocity. Second, the front involves a depletion zone with an excess of vacant sites. The total excess {Delta}{sub k} increases logarithmically, {Delta}{sub k} {approx_equal}ln k, with the distance k from the front. Third, the front exhibits ageing -- young fronts are vigorous but old fronts are sluggish. We investigate these phenomena using a quasi-static approximation, direct solutions of small systems and numerical simulations.

    2009-01-01

    The characteristics of Pb2+ adsorption on the surface of birnessites with different average oxidation states (AOS) of Mn, synthesized under acidic and alkali conditions, were investigated. The results indicated that the amount of adsorbed Pb2+ increased with the increase of Mn AOS in birnessites. The amount of Pb2+ adsorbed positively correlated with the amount of released Mn2+, H+ and K+ (r = 0.9962 > 0.6614, n = 14, α = 0.01). The released Mn2+, H+ and K+ were derived mostly from the corresponding cations adsorbed on the vacant sites. The maximum amount of adsorbed Pb2+ increased with the increasing vacant cation sites, leading to an increase of the total amount of released Mn2+, H+ and K+, and the increased likelihood for two Pb2+ adsorbed in the region of one side of a vacant site.

    Disorder in Gd2(Ti(1-y)Zry)2O7 pyrochlores, for y = 0.0-1.0, is investigated by Ti 2p and O 1s near-edge X-ray absorption fine structure spectroscopy. Ti(4+) ions are found to occupy octahedral sites in Gd2Ti2O7 with a tetragonal distortion induced by vacant oxygen sites. As Zr substitutes for Ti, the tetragonal distortion decreases, and Zr coordination increases from 6 to 8. The migration of oxygen ions from 48f or 8b sites to vacant 8a sites compensate for the increased Zr coordination, thereby reducing the number of vacant 8a sites, which further reduces the tetragonal distortion and introduces more disorder around Ti. This is evidence for simultaneous cation disorder with anion migration.

  14. Methods used by accredited dental specialty programs to advertise faculty positions: results of a national survey.

    2011-01-01

    The various reasons for the current and projected shortages of dental faculty members in the United States have received much attention. Dental school deans have reported that the top three factors impacting their ability to fill faculty positions are meeting the requirements of the position, lack of response to position announcement, and salary/budget limitations. An electronic survey sent to program directors of specialty programs at all accredited U.S. dental schools inquired about the number of vacant positions, advertised vacant positions, reasons for not advertising, selection of advertising medium, results of advertising, and assistance from professional dental organizations. A total of seventy-three permanently funded full-time faculty positions were reported vacant, with 89.0 percent of these positions having been advertised in nationally recognized professional journals and newsletters. Networking or word-of-mouth was reported as the most successful method for advertising. The majority of those responding reported that professional dental organizations did not help with filling vacant faculty positions, but that they would utilize the American Dental Association's website or their specialty organization's website to post faculty positions if they were easy to use and update.

    1993-11-01

    In 1990, DOE initiated a nationwide evaluation of its Weatherization Program, with assistance from Oak Ridge National Laboratory and an advisory group of 40 weatherization professionals, program managers, and researchers. The evaluation is comprised of three impact studies covering the Program`s major market segments: Single-family homes, mobile homes, and dwellings in small (2 to 4-unit) multifamily buildings (the Single-Family Study), Single-family homes heated primarily with fuel oil (the Fuel-Oil Study), and Dwellings in buildings with five or more units (the Multifamily Study). The Single-Family Study, the subject of this report, is a critical part of this coordinated evaluation effort. Its focus on single-family dwellings, mobile homes, and dwellings in small multifamily buildings covers 83% of the income-eligible population and 96% of the dwellings weatherized during Program Year 1989. The first phase of the Single-Family Study involved the analysis of a massive data base of information collected from 368 local weatherization agencies and 543 electric and gas utilities. This analysis resulted in energy-saving and cost-effectiveness estimates for the Weatherization Program and the identification of a set of ten high-performing agencies located throughout the country. The second phase, which is the subject of this report, involves a ``process`` evaluation of these ten high performers, aimed at identifying those weatherization practices that explain their documented success.

  11. Evaluation of Kolmogorov - Smirnov Test and Energy Detector Techniques for Cooperative Spectrum Sensing in Real Channel Conditions

    Directory of Open Access Journals (Sweden)

    D. Lekomtcev

    2015-06-01

    Full Text Available The cognitive radio technology allows solving one of the main issues of current wireless communication technologies, namely a deficit of vacant spectrum. A dynamic spectrum access used in the cognitive radio networks (CRN gives an ability to access an unused spectrum in real time. Cooperative spectrum sensing is the most effective method for spectrum holes detecting. It combines sensing information of multiple cognitive radio users. In this paper, an experimental evaluation of spectrum sensing methods based on the Kolmogorov - Smirnov statistical test and Energy Detector using the Universal Software Radio Peripheral (USRP devices synchronized through a MIMO cable and with further processing in the GNU Radio and Matlab software are presented. Three hard decision fusion schemes are analyzed. Simulation comparison between these rules is presented via Receiver Operating Characteristic (ROC curves. The influence of real channel with interferences is compared in contrast to commonly assumed AWGN channel model of vacant channel noise.

  12. Web placement in sympatric linyphiid spiders ( Arachnida, Araneae): Individual foraging decisions reveal inter-specific competition

    Science.gov (United States)

    Herberstein, Marie Elisabeth

    1998-02-01

    The distribution of two sympatric web spiders, Frontinellina frutetorum (C. L. Koch) and Neriene radiata (Walckenaer) (Araneae: Linyphiidae) was studied on an area of forest regrowth in eastern Austria. Both species utilised significantly different heights on young conifer trees to construct their webs. F. frutetorum selected higher vegetation layers, whereas N. radiata constructed its webs, closer to the ground. This distribution may either be evidence of competition for web space or it may reflect specific distribution patterns unrelated to spider density. An experiment showed that when spiders of either species were released onto vacant trees they selected similar vegetation heights for web construction. On trees already occupied by a heterospecific individual however, F. frutetorum placed its webs significantly higher and N. radiata significantly lower compared to web placement on vacant trees suggesting that F. frutetorum and N. radiata compete for web space.

    Zhang, Pei-feng; Hu, Yuan-man; He, Hong-shi; Xiong, Zai-ping; Liu, Miao

    2010-12-01

    In this paper, three-dimensional building information was extracted from high resolution satellite image based on Barista software. Combined with ArcGIS software, the dynamic changes of the building landscape in Tiexi District of Shenyang City during urban renewal process were analyzed from the conversion contribution rate, building density, average building height, and built-up area rate. It was found that during this urban renewal process, four dominant landscape types (vacant lot, residential building, industrial building, and road) were the main parts of the landscape changes. The areas of vacant lot, residential building, commercial building, and road increased, while that of industrial building decreased. The building density decreased, while the average building height increased. There was an obvious regional variation in building landscape. The building density in industrial district was higher than that in residential district, while the average building height was in adverse. The further from the city center, the lower the building density and building average height.

    Ghémard, Geneviève; Etienne, Jean; Schiffmacher, Gérard; Flahaut, Jean

    1982-11-01

    The ( LS) 2Te 1 + x compounds have an orthorhombic subcell, with a layered structure and vacant Te sites, and a monoclinic superstructure ( a = b = 6.658, c = 13.657 Å, γ = 102°43' for (HoS) 2Te 1.34). The order-disorder transition occurs at about 450°C. In the superstructure Te planes between ( L4S) tetrahedra layers are ordered with {B2}/{m} symmetry; however, some sites remain partially vacant. The S atoms conserve mmm symmetry, but the metallic atoms are slightly displaced from their substructure position ( R = 0.037). Ordering occurs so that each Te plane can be oriented in two different ways. Therefore, there are two kinds of domains, with respect to a twinning rule. These domains are observed by direct-imaging high-resolution electronic microscopy and are about 100 Å wide.

  15. Comparative theoretical study of adsorption of lithium polysulfides (Li2Sx) on pristine and defective graphene

    Science.gov (United States)

    Jand, Sara Panahian; Chen, Yanxin; Kaghazchi, Payam

    2016-03-01

    Adsorption of Li2Sx on pristine and defective (Stone-Wales (SW) and vacancy) graphene is studied using density functional theory. Results show that the interaction between Li2Sx and graphene is dominated by dispersion interaction (physisorption), which depends on the size of molecule as well as the existence and type of defect sites on graphene. We find that single Li2Sx molecules interact only slightly stronger to the SW sites than to the defect-free sites, but they interact very strongly with single-vacant defects. In the later cases, the vacant site catches one S atom from the Li2Sx molecule, leading to the formation of a Li2Sx-1 molecule, which adsorbs weakly on the created S-doped graphene. This study suggests that defect sites can not improve the ability of graphene to catch lithium polysulfides in Li-S batteries.

    2016-12-01

    To determine if blight remediation of abandoned buildings and vacant lots can be a cost-beneficial solution to firearm violence in US cities. We performed quasi-experimental analyses of the impacts and economic returns on investment of urban blight remediation programs involving 5112 abandoned buildings and vacant lots on the occurrence of firearm and nonfirearm violence in Philadelphia, Pennsylvania, from 1999 to 2013. We adjusted before-after percent changes and returns on investment in treated versus control groups for sociodemographic factors. Abandoned building remediation significantly reduced firearm violence -39% (95% confidence interval [CI] = -28%, -50%; P urban residents that may create physical opportunities for violence by sheltering illegal activity and illegal firearms. Urban blight remediation programs can be cost-beneficial strategies that significantly and sustainably reduce firearm violence.

  18. Current organic waste recycling and the potential for local recycling through urban agriculture in Metro Manila.

    Hara, Yuji; Furutani, Takashi; Murakami, Akinobu; Palijon, Armando M; Yokohari, Makoto

    2011-11-01

    Using the solid waste management programmes of three barangays (the smallest unit of local government in the Philippines) in Quezon City, Metro Manila, as a case study, this research aimed to further the development of efficient organic waste recycling systems through the promotion of urban agricultural activities on green and vacant spaces. First, the quantity of organic waste and compost produced through ongoing barangay projects was measured. The amount of compost that could potentially be utilized on farmland and vacant land within the barangays was then identified to determine the possibility of a local recycling system. The results indicate that, at present, securing buyers for compost is difficult and, therefore, most compost is distributed to large neighbouring farm villages. However, the present analysis of potential compost use within the barangay demonstrates that a more local compost recycling system is indeed feasible.

    Rotational Supercavitating Evaporator (RSCE) has been proposed as a new technology for seawater desalination. However, thermodynamic characteristics of rotational supercavitation are still vacant. In this paper, numerical simulations are conducted on the supercavitating flows around a 3D rotating blade of RSCE with different rotational speeds and extraction pressures. Energy effect is taken into consideration in the simulation and thermodynamic characteristics of rotational supercavitation are obtained. Rotational supercavitation has a larger convective heat transfer coefficient than the boiling on a heated wall.

    Urban authorities in Europe are confronted with increasing demands by urban dwellers for allotment gardens, but vacant urban soil tends to be scarce and/or polluted by past industrial activities. A possible solution for local authorities could therefore be to promote rooftop gardening. However little technical information exists on certain forms of rooftop urban agriculture, called Z-Farming. In 2012, a pilot experiment was run in Paris (France). Simple and cheap systems of rooftop gardening ...

    Full Text Available Los investigadores han sido consistentes en el asesoramiento a los directivos de que inviertan en la marca del empleador de la organización, con base en el argumento de que se beneficiará la práctica del reclutamiento. Sin embargo, esta premisa ha sido mayormente sostenida siguiendo un punto de vista organizativo. Como tal, los efectos de marca del empleador sobre el comportamiento de búsqueda de empleo de los candidatos que solicitan una vacante siguen siendo indeterminados. El objetivo principal de este estudio es conocer si la marca del empleador limita la conducta de búsqueda de los solicitantes. Nosotros proponemos que los candidatos desarrollan el deseo de solicitar una vacante a través de un proceso que tiene los atributos de la organización como predictor y el atractivo como su mediador. A continuación, investigamos si y cómo la marca del empleador restringe este proceso, mediante la evaluación de su efecto moderador. Utilizando la metodología de análisis confirmatorio, encontramos que la marca del empleador modera el proceso de búsqueda de trabajo propuesto. Una marca de empleador positiva ha fortalecido el proceso conducente a la intención de solicitar una vacante, en comparación con marcas de empleador neutrales o negativas. Esto explica el deseo de los candidatos de solicitar a una vacante. En base a nuestros resultados, sugerimos recomendaciones a los profesionales, relativas a la eficacia del reclutamiento.

    Techniques for fabricating nanospaced electrodes suitable for studying electron tunneling through metal-molecule-metal junctions are described. In one approach, top contacts are deposited/placed on a self-assembled monolayer or Langmuir-Blodgett film resting on a conducting substrate, the bottom contact. The molecular component serves as a permanent spacer that controls and limits the electrode separations. The top contact can be a thermally deposited metal film, liquid mercury drop, scanning probe tip, metallic wire or particle. Introduction of the top contact can greatly affect the electrical conductance of the intervening molecular film by chemical reaction, exerting pressure, or simply migrating through the organic layer. Alternatively, vacant nanogaps can be fabricated and the molecular component subsequently inserted. Strategies for constructing vacant nanogaps include mechanical break junction, electromigration, shadow mask lithography, focused ion beam deposition, chemical and electrochemical plating techniques, electron-beam lithography, and molecular and atomic rulers. The size of the nanogaps must be small enough to allow the molecule to connect both leads and large enough to keep the molecules in a relaxed and undistorted state. A significant advantage of using vacant nanogaps in the construction of metal-molecule-metal devices is that the junction can be characterized with and without the molecule in place. Any electrical artifacts introduced by the electrode fabrication process are more easily deconvoluted from the intrinsic properties of the molecule.

    2015-11-01

    Full Text Available While the multiple benefits of urban greening are known, implementing green projects in post-industrial urban centers—where economic development, community revitalization and job creation are prioritized—requires accurate data that are relevant to local advocates and decision-makers. Municipal tax rolls are often used to identify vacant properties but are not necessarily up-to-date or do not contain detailed attributes about vacant properties. The Rutgers University Center for Urban Environmental Sustainability (CUES partnered with the City of Trenton and Isles, Inc., a local non-governmental organization (NGO, to conduct a unique smart-phone based city-wide property survey that captured property data not available in the city's tax rolls. Spatial analysis of data was completed and compared to a baseline vacant property survey. Having current and accurate data has empowered Trenton to develop a strategy to redevelop their unproductive tax base, and has given an NGO the tools needed to draft a Master Plan Revision to institutionalize the need for green redevelopment. This paper discusses data collection and analysis methodology and recommendations to “green” the City of Trenton.

    2015-07-01

    Full Text Available Policies focusing on enforcing property code violations and the improvement of vacant properties are argued to be more efficacious than demolition policies to fight urban blight. This study applies parcel level data to a multi-year hybrid modeling structure. A fine-grained analysis is conducted on the dynamic patterns of abandonment and demolition for a unique period of four years before and after the City of Buffalo’s stepped-up demolition efforts. Results showed that proximity to vacant and abandoned properties, sustained over the years, had the greatest impact on the possibility of a property being abandoned. The second greatest positive impact on property abandonment was small lot front size. Results also showed that neighborhood vacancy density had the greatest negative impact on surrounding housing sales prices over the years. There was no significant impact of demolition on housing sales prices. These findings suggested that the City should aim to have more incentive programs that are tailored to control the number of vacant properties, rather than focusing primarily on demolition-oriented programs.

    2016-12-01

    In 1785 William Herschel published a paper in the Philosophical Transactions containing the remarkable section "An opening or hole". It describes an unusual vacant place in Scorpius. This matter falls into oblivion until Caroline Herschel initiated a correspondence with her nephew John in 1833. It contains Herschel's spectacular words "Hier ist wahrhaftig ein Loch im Himmel" ("Here truly is a hole in the sky"). About a hundred years later, Johann Georg Hagen, Director of the Vatican Observatory, presented a spectacular candidate for the 'hole', discovered in 1857 by Angelo Secchi in Sagittarius and later catalogued by Edward E. Barnard as the dark nebula B 86. Hagen's claim initiated a debate, mainly in the Journal of the British Astronomical Association, about the identity of Herschel's 'object'. Though things could be partly cleared up, unjustified claims still remain. This is mainly due to the fact that original sources were not consulted. A comprehensive study of the curious 'hole' is presented here. It covers major parts of the epochal astronomical work of William, Caroline and John Herschel. This includes a general study of 'vacant places', found by William Herschel and others, and the speculations about their nature, eventually leading to the finding that dark nebulae are due to absorbing interstellar matter. Some of the 'vacant places' could be identified in catalogues of dark nebulae and this leads to a 'Herschel Catalogue of Dark Nebulae' - the first historic catalogue of its kind.

  13. Data-Driven Rightsizing: Integrating Preservation Into the Legacy Cities Landscape

    2017-08-01

    Legacy cities, whose built environments are undergoing transformations due to population loss, are at a critical juncture in their urban history and the historic preservation field has an important role to play. Rapid mobile surveys provide an opportunity for data collection that expands beyond traditional historic criteria, and positions preservationists to be proactive decision-makers and to align with multi-disciplinary partners. Rapid mobile surveys are being utilized in conjunction with in-depth data analysis of comprehensive livability metrics at the parcel, neighborhood, and citywide levels to develop recommendations for reactivating vacant properties. Historic preservationists are spearheading these efforts through a tool called Relocal, which uses 70-85 distinct metrics and a community priority survey to generate parcel-level recommendations for every vacant lot and vacant building in the areas in which it is applied. Local volunteer-led rapid mobile surveys are key to gathering on-the-ground, real-time metrics that serve as Relocal's foundation. These new survey techniques generate usable data sets for historic preservation practitioners, land banks, planners, and other entities to inform strategic rightsizing decisions across legacy cities.

    Voluntary nurse turnover, which is costly and disrupts patient care, has not been studied as an organizational phenomenon within substance abuse treatment organizations. In this exploratory study, we examined the frequency and correlates of nurse turnover within treatment programs affiliated with the National Drug Abuse Treatment Clinical Trials Network (CTN). During face-to-face interviews conducted in 2005–2006, 215 program administrators reported the number of nurses currently employed. Leaders of programs with nursing staff then described the number of nurses who had voluntarily quit in the past year, the degree to which filling vacant nursing positions was difficult, and the average number of days to fill a vacant position. About two-thirds of these programs had at least one nurse on staff. In programs with nurses, the average rate of voluntary turnover was 15.0%. Turnover was significantly lower in hospital-based programs and programs offering adolescent treatment, but higher in facilities offering residential treatment. The majority of administrators indicated that filling vacant nurse positions was difficult and took more than two months to complete. These findings suggest that nurse turnover is a significant issue facing many substance abuse treatment facilities. Efforts to improve retention of the addiction treatment workforce should be expanded to include nursing professionals. PMID:21177062

    One of a dairy production company producing pasteurized milk and yoghurt drink, whose brand has widely known in East Java, has a factory plant in Batu City, one of tourism destinations in Indonesia. Behind the factory plant, there is a vacant land with an estimated total area of 2.3 ha and a vacant cowshed which had not been used for cattle ranching. Because of that, the company planned to develop the vacant land as a dairy farm and plant based ecotourism. In addition, dairy farm and dairy plant based tourism attractions are still rarely found in Batu. Thus, the first aim of this study was to analyse the potencies of the company that related to future plans of ecotourism built. The second aim was to set up the strategies that can be done in order to actualize the ecotourism project. The next aim was to plan the ecotourism, especially the facilities planning and the facilities arrangement on the vacant land. Strategic management approach was used to analyse the potencies and to determine the strategies. To select the proper facilities, tourists were asked to give appraisal by using questionnaire. Appraisal result was mapped onto four quadrants spatial map to see advantages and shortcomings of each facility along with choosing the right facilities to be built. Those facilities and tourist activities were compared with ecotourism criteria to make sure that the facilities were appropriate to provide not only entertainment but also ecotourism function. To arrange the chosen facilities, the step in Systematic Layout Planning were conducted to generate a propose layout of facilities arrangement. Based on potencies analysis, in Internal-External matrix, the company current position was on quadrant 2 (grow and build), with the most appropriate strategy was intensive or integrative. The proposed strategies were to build the new infrastructure, to renovate cowshed, and to add new tourism facilities on the land. There were 11 selected facilities based on MDS. Moreover, based

    The report presents an evaluation of the potential for energy improvements in existing dwellings based on calculations. The evaluation concludes that it is possible to save at least 30 PJ by isolating outer walls, floors, roofs, and optimize windows in existing dwellings. The saving potential is dependent on year of construction and type. The largest energy savings can be reached in dwellings build before 1930, but also single-family houses build in the period 1961 to 1972 have a large energy saving potential. Overall the energy saving potential is largest in the group of single-family houses as they constitute almost half of the total inhabited area of Denmark. (BA)

    More than 80% of energy used in households is dedicated to space heating. Large potential energy savings have been identified in the existing housing stock. Energy labelling of single-family houses is seen as an important instrument to provide new house owners with information on efficient energy saving investments that can be made on the house. This paper evaluates the effects of the Danish Energy Labelling Scheme on energy consumption in existing single-family houses with propensity score matching using actual consumption of energy and register data describing the houses and households. We do not find significant energy savings due to the Danish Energy Labelling Scheme. (Author)

    About 25 to 30% of all newly constructed single-family houses in Switzerland are equipped with heat pump systems. This increasing attractivity is partly due to new techniques, e.g. microprocessor control, as well as to higher component efficiencies, a more efficient heat exchange technology, and to the compactness of systems. Active solar energy conversion, i.e. by means of solar collectors, is another technique which is predominantly applied for water heating in single-family buildings. Public investments in this field are scarce. (BWI).

  8. Structural characterization of birnessite: influence of the way of synthesis; Caracterisation structurale de la birnessite: influence du protocole de synthese

    Birnessite is a lamellar manganese oxide whose layers are built up of edge sharing MnO{sub 6} octahedra. The presence of hetero-valent Mn cations and/or of vacant sites in these layers leads to a charge deficit compensated for by the presence of hydrated cations in the interlayer space. Because of their high specific area and of their strong oxidative character, these ubiquitous manganese oxides play a fundamental role in the fate of organic and metallic pollutants in the environment, but our imperfect knowledge of their structure limits the understanding and the modeling of this impact. This study aimed at classifying all different kinds of birnessite obtained using existing synthesis protocols according to two relevant criteria: layer symmetry and layer stacking mode, and at determining the structure of several essential varieties using X-ray and electron diffraction. Layers of hydrothermal birnessite contain vacant sites and, as a result, possess an hexagonal symmetry. Their stacking mode is 3R. In high-temperature birnessites, adjacent layers have an opposite orientation, which results in a two-layer polytype. The symmetry of these layers, linked to the origin of the layer charge deficit, depends on the temperature of synthesis. At 800 C the presence of vacant sites results in an hexagonal symmetry (2H polytype). At 1000 C, the layer charge deficit originates from the presence of Mn{sup 3+} cations in the layer lowering the layer symmetry (2O polytype). A variety of chemical and structural heterogeneities was also described in these samples, along with the occurrence of a new type of structural disorder. Finally we proved both the fundamental link between the origin of the layer charge and the layer symmetry, and the influence of physico-chemical parameters during synthesis (temperature, average manganese oxidation degree, nature of the interlayer cation) on the structure of the obtained compound. The chemical and thermal stabilities of these birnessites are

    Acid birnessite was treated with Na4P2O7 at pH 2, 4, 5 respectively. After the treatments, the species and content of manganese ion in the complex solution, and the variation of average oxidation state (AOS) of Mn in birnessite, and the amount of adsorbed Pb2+ and released Mn2+, H+ during the Pb2+ adsorption were investigated. The results indicate that after acid birnessite, the AOS of Mn is 3.670 which is treated by Na4P2O7 at different pH, Mn( III) located in the layer edge and part of Mn(III) located in the interlayer are released to the solution through complexation with Na4P2O7. The content of Mn(III) in the structure of original birnessite is very low. Small amount of Mn(II), which accounts for 4.70%-7.46% in the molar percentage of total released Mn, is also released simultaneously. The AOS of Mn of birnessites after treatment increases to 3.783 (pH 2), 3.786 (pH 4), 3.824 (pH 5) respectively. While the crystal structure of birnessite does not change after treatment, the amount of Mn(III) located above or below vacant cation sites decreases, and the amount of H+ located above or below vacant cation sites goes up in the structure of birnessites. The amount of vacant cation sites responsible for Pb2+ adsorption increases, which lead to the increase of the maximum amount of adsorbed Pb2+. Additionally, the distribution of Mn(III) in the structure of acid birnessite is deduced. About one sixth of Mn(III) locates in the layer edge, and five sixths of Mn(III) locates in the interlayer and the non layer edge.

    An adolescent girl with blond hair, her family, and classmates noted that her hair was progressively turning green. Initially the green color was thought to be secondary to chlorine from the local swimming pool. This was not the real cause. The chlorotrichosis was actually caused by an excessive amount of dissolved copper from copper pipes in the home plumbing system. Copper had leached from the plumbing and accumulated in the pipes because the rented house had been vacant for many months. Risk factors for chlorotrichosis include light-colored hair, copper plumbing, long periods when the water was not thoroughly flushed out of the copper pipes, and frequent shampooing.

    2012-01-01

    The planet Kepler-16b is known to follow a circumbinary orbit around a double system of two main-sequence stars. We construct stability diagrams in the "pericentric distance - eccentricity" plane, which show that Kepler-16b is in a hazardous vicinity to the chaos domain - just between the instability "teeth" in the space of orbital parameters. Kepler-16b survives, because it is close to the half-integer 11/2 orbital resonance with the central binary. The neighbouring resonance cells are vacant, because they are "purged" by Kepler-16b, due to overlap of first-order resonances with the planet.

    Combining in-depth neutron diffraction and systematic bulk studies, we discover that the √5 × √5 Fe vacancy order, with its associated block antiferromagnetic order, is the ground state with varying occupancy ratios of the iron 16i and vacancy 4d sites across the phase-diagram of KxFe2-ySe2. The orthorhombic order, with one of the four Fe sites vacant, appears only at intermediate temperatures as a competing phase. The material experiences an insulator to metal crossover when the √5 × √5 order is highly developed. Superconductivity occurs in such a metallic phase.

    We define the model of two-dimensional random interlacements using simple random walk trajectories conditioned on never hitting the origin, and then obtain some properties of this model. Also, for a random walk on a large torus conditioned on not hitting the origin up to some time proportional to the mean cover time, we show that the law of the vacant set around the origin is close to that of random interlacements at the corresponding level. Thus, this new model provides a way to understand the structure of the set of late points of the covering process from a microscopic point of view.

    Further investigations on the recently reported YBCO-PbS HTS system are reported. The system is found to have conducting BaPbO[sub 3] as a second phase, which fills the intergrain vacant spaces forming a composite-like microstructure. Thermoanalytical investigations revealed that PbS addition enhances the synthesis of the Y-123-phase and lowers the temperature of partial melting of this phase, which is essential to further reduce the voids. The metallurgical reaction occurring during sintering is also determined and investigated. It is shown that these composite superconducting materials have better normal-state, superconducting, and mechanical properties. (orig.)
