    Monitoring removal of lead (Pb) paint from steel structures usually involves analysis of environmental samples for total lead and determination of blood Pb levels of employees involved in the Pb paint removal. We used high precision Pb isotopic tracing for a bridge undergoing Pb paint removal to determine if Pb in the environmental and blood samples originated from the bridge paint. The paint system on the bridge consisted of an anti-corrosive red Pb primer top-coated with a Micaceous Iron Oxide (MIO) alkyd. Analysis of the red Pb primer gave uniform isotopic ratios indicative of Pb from the geologically-ancient Broken Hill mines in western New South Wales, Australia. Likewise waste abrasive material, as anticipated, had the same isotopic composition as the paint. The isotopic ratios for other samples lay on 2 separate linear arrays on a(207)Pb/(204)Pb versus (206)Pb/(204)Pb diagram, one largely defined by gasoline and the majority of the ambient air data, and the other by data for one sample each of gasoline and ambient air and underwater sediments. Isotopic ratios in background ambient air samples for the project were characteristic of leaded gasoline. Air sampling during paint removal showed a contribution of paint Pb ranging from about 20 to 40%. Isotopic ratios in the blood of 8 employees prior to the commencement of work showed that 6 of these had been previously exposed to the Broken Hill Pb possibly from earlier bridge paint removal projects. One subject appeared to have increased exposure to Pb probably from the paint renovations.

  9. Lead-based paint in dwellings: The potential for contamination of the home environment during renovation.

    Science.gov (United States)

    Inskip, M J; Hutton, M

    1987-12-01

    The quantity and particle size characteristics of lead in dust released during three different paint removal techniques was determined under controlled conditions and in situ in a dwelling. Air-lead and deposited dust-lead levels were highest after sanding but 'burning-off' and 'hot-air' removal methods also produced significant contamination. The importance of dust particle-size and lead is discussed in relation to the potential hazard to home renovators via inhalation and to children via the 'hand-to-mouth' route.

  10. Lead exposure among workers renovating a previously deleaded bridge: comparison of trades, work tasks.

    2000-01-01

    Airborne and surface lead exposures were evaluated for construction trade groups at a previously deleaded bridge renovation site in the midwestern United States. Although all lead-based paint should have been removed, old layers of leaded paint were still present on some sections of the bridge. Ironworkers performing metal torch cutting had the highest exposures (188 microg/m3), followed by workers engaged in clean-up operations and paint removal (p contaminated with lead. Heavy equipment operators with low airborne lead exposure had the highest levels of surface contamination in personal vehicles (3,600 microg/m2). Laborers cleaning structural steel with compressed air and ironworkers exposed to lead fumes from cutting had the highest concentrations of lead dust on clothing (mean 4,766 microg/m2). Handwashing facilities were provided, but were infrequently used. No separate clothes changing facility was available at the site. The potential for "take-home" contamination was high, even though this site was thought to be relatively free of lead. Construction contractors and their workers need to be aware that previous deleading of a site may not preclude exposure to significant amounts of lead.

    In the framework of the IEA SHC Programme, a Task on building renovation was initiated, `Task 20, Solar Energy in Building Renovation`. In a part of the task, Subtask C `Design of Solar Renovation Projects`, different solar renovation demonstration projects were developed. The objective of Subtask C was to demonstrate the application of advanced solar renovation concepts on real buildings. This report documents 16 different solar renovation demonstration projects including the design processes of the projects. The projects include the renovation of houses, schools, laboratories, and factories. Several solar techniques were used: building integrated solar collectors, glazed balconies, ventilated solar walls, transparent insulation, second skin facades, daylight elements and photovoltaic systems. These techniques are used in several simple as well as more complex system designs. (au)

    Scientists at universities across Iraq are actively working to report actual incidents and accidents occurring in their laboratories, as well as structural improvements made to improve safety and security, to raise awareness and encourage openness, leading to widespread adoption of robust Chemical Safety and Security (CSS) practices. The improvement of students’ understanding of concepts in science and its applications, practical scientific skills and understanding of how science and scientists work in laboratory experiences have been considered key aspects of education in science for over 100 years. Facility requirements for the necessary level of safety and security combined with specific requirements relevant to the course to be conducted dictate the structural design of a particular laboratory, and the design process must address both. This manuscript is the second in a series of five case studies describing laboratory incidents, accidents, and laboratory improvements. We summarize the process used to guide a major renovation of the chemistry instructional laboratory facilities at Al-Nahrain University and discuss lessons learned from the project.

    Full Text Available Building owners are encouraged to reduce energy use in order to both contribute to national energy-saving goals and reduce the costs of heating and operation. It is important to choose the most optimal renovation measures available so as to achieve cost-effective energy use while maintaining excellent indoor environments, without sacrificing architectural quality or negatively affecting the environment. Building owners and managers often have neither the time nor the expertise required to properly evaluate the available renovation options before making a final decision. Renovation measures are often calculated to repay investments in a short time, rather than taking into account life-cycle costs (LCC, despite the fact that a thoughtful, comprehensive renovation is often more cost-effective in the long run. This paper presents a systematic approach for evaluating different renovation alternatives based on a number of sustainability criteria. The methodology has been verified using three multi-family apartment buildings in Sweden. The benefit of using the proposed methodology is made clear through a comparison between the different renovation alternatives from a sustainability perspective, and will hopefully serve as encouragement to choose renovation measures which involve marginally increased investments but lead to significant environmental and social benefits in the long-term.

  9. Investigation of Contemporary Performance Measurement Systems for Production Management of Renovation Projects

    Directory of Open Access Journals (Sweden)

    Yash Singh

    2014-01-01

    Full Text Available Renovation projects exhibit complex characteristics due to the presence of constraints that lead to cost and schedule overruns. Numerous researchers have concluded that the performance of renovation projects is typically lower than that of new construction projects. This paper discusses the initial phases of a research conducted at Michigan State University, which focused on developing a framework for production management of renovation projects. The emphasis of this paper is on the findings from literature review and interviews, pertinent to performance measurement in renovation projects that led to the framework development. However, the framework development and the framework itself have not been discussed. This paper primarily addresses two questions: (1 what are the complexities of renovation projects that lead to underperformance in cost, time, and quality? and (2 what are the limitations of state-of-the-art construction performance measurement systems for managing production in renovation projects? Interviews of 10 construction companies were conducted to identify current practices of production management in renovation projects. This research observed a lack of a formal production management process in renovation projects, with a limited use of performance measurement systems. The research identified essential attributes for avoiding schedule and cost overruns on renovation projects.

    2014-07-01

    Full Text Available In Sweden and in other countries, building owners are encouraged to help reduce energy consumption, both in order to contribute to national energy saving goals and, in terms of their own interests, to reduce the costs of heating and operation of the building. However, it is important to pursue the most optimal strategy available so as to achieve cost-effective energy usage while simultaneously maintaining excellent indoor environments, without sacrificing the architectural quality or negatively affecting the environment. Building managers often do not have the time or expertise required to make a proper evaluation of the available options before making a final decision. Renovation measures are often considered in the light of repaying investments in a short time rather than taking into account life cycle costs, despite the fact that a thoughtful, comprehensive renovation is often more cost-effective in the long run. This article presents a systematic approach for evaluating different renovation alternatives based on sustainability criteria. A methodology has been developed to evaluate different renovation alternatives from environmental, economic, and social perspectives. The benefit of using the proposed methodology is that building managers who face a major renovation work are provided with a clear comparison between the different renovation options, viewed from a sustainability perspective, this may facilitate, in the long run, a culture in which renovation measures which involve marginally increased costs, but are seen to lead to significant environmental and social benefits, will be considered and carried out.

    Full Text Available Renovation processes are complex and there is a risk of underestimating architectural, cultural, and social values in favor of exterior and interior upgrading, energy efficiency and financing. A synthesized, systematic process is needed for making decisions about renovation measures. The aim of this paper is to survey decision-making procedures aimed for sustainable renovation. We inventory existing tools and methodologies based on (a a literature review and (b results from a workshop with participants from the Swedish buildings sector, academia, and other stakeholders. Our results show that there are many tools available but few seem to have reached acceptance in renovation. None of the more established methods and tools addresses a complexity that balances material and immaterial values and they are often too specific. There is a need for simplified tools, especially for evaluating more intangible, experienced values. Instead of one comprehensive tool preferably a methodology for renovation should be developed with references to different tools. In the building sector, renovation should be considered a service-minded process rather than a merely technical one as often is the case in new construction. There is a need to clarify the process and the meaning of the terms, and that need is even more urgent when it comes to the values that are more difficult to define.

  8. Energy and environmental assessment in connection with renovation; Energi- og miljoevurdering ved renovering

    Environmental assessments were carried out for renovation projects that more energy saving measures than usual for renovation projects and also for more traditional renovation of small flats. These environmental assessments were carried out primarily with a view to test the suitability of the BEAT 2000 simulation program for energy and environmental assessments for renovation projects, but also with a view to clarify the importance of doing more comprehensive environmental assessments. BEAT 2000 tests will show whether the assessment tool should be changed to include renovation projects and also of the tool's database should be extended with specific materials and building elements used in renovation. Experience gained on the project shows that environmental assessment of renovation projects does not in principle differ from assessments of new building. Further data need to be collected, especially in relation to new and not commonly used energy-saving solutions and the selected materials. These are characterised by occurring not only in connection with renovation but also with new buildings where they can generally be used. It may be added that an extended database including materials for new and not commonly used energy-saving solutions will facilitate environmental assessment of most traditional plumbing and electrical installations as the same materials are extensively used. They can also be used in connection with renovation and new building. Moreover the database should be extended to include a number of typical building elements used for renovating. However, it should be expected that new and not commonly used building elements will be used in connection with renovation, their use dictated by specific physical conditions of old houses. Therefore it will be impossible to establish a database of building elements for renovation that will be as comprehensive as building elements for new buildings. It will often be necessary for the user himself to define

  9. Distinctiveness of Initial Preform Properties in Renovation

    Full Text Available Technologies of renovation form a special group of resource-and energy saving technological processes as they are, by definition, already aimed either at increasing resource of the objects satisfying needs of the society life support and practical activities in different spheres, or at extension of their life cycle including a reuse of material from which they are made. Renovation is used where there is a material object, which does not meet requirements of standard or technical documentation.A characteristic feature of the renovation technologies is lack of procedure for a choice of the preform as in all cases an initial preform is the renovation object itself. Thus each object, acting as an initial preform, has the exclusively individual properties, including technological ones.Distinctiveness of renovation object properties is correlated, first of all, with the personified conditions of formation and (or change of condition of their properties in time at all stages of life cycle (production – transportation – warehousing – operation starting with a preform material when manufacturing under all types of loadings (technological and operational. As a result each object forms its "history" of loading and damages and, therefore, its information base which has to consider the phenomenon of “heredity of life cycle”. The term "heredity of life cycle" characterizes information support of object at any moment under review, including both information of technological inheritance, and data of operational heredity.As a result at every moment of time we have a product with a set of new, uncertain properties caused by the phenomena of heredity of life cycle. These properties are individual for each object to be renovated, which changed its status for the status of initial preform for different types of renovation technologies. This is one of the most important distinctions of renovation technology from the technology used to manufacture a new

    V. M. Yaroslavtsev

    2014-01-01

    Full Text Available Nowadays, technologists in charge of repair, restoration, modernization, and utilization of engineering and other tangible objects widely use the concepts "renovation" and "renovation technologies" pioneered at BMSTU. In forming a new field of science these concepts, in the proper sense of the word, are of composite, generalized character. They concern all the activities and technologies aimed at increasing an object resource or its lifecycle extension, including object material recycling.In the cutting-edge renovation technologies an object (part, assembly, machine, etc. damaged in the operating process is considered to be an initial billet. In renovation, one of the most widespread kinds of initial billets is a damaged part.Such a part can be used again, if, for example, it has saved its material properties in full measure while only contact surfaces or parts of these surfaces have become damaged, and at a point of renovation they can be restored for recycling. If a part has lost its initial properties in full bulk of material, it may be reusable in the assemblies and machines with less rigid requirements for material properties.Or in case of properties loss below the permissible level a damaged part-billet is utilized. Thus, the part-billet state at the point of renovation defines the kind of renovation technology and the main (basic technological method to effect on the damaged part, as well as a set and a sequence of technological methods in general manufacturing process of renovation.However renovation technologies are used not only at the repair and restoration stages after operation-service. So, at the manufacturing stage of a new product to provide the quality to raise a resource are applied the same technological methods as renovation technologies for the objects damaged at the stage of operation. Besides, it is known that at the manufacturing stage a part quality depends not only on the last operation, but also on the features of

  15. Integrated project delivery methods for energy renovation of social housing

    studies is on analysing the implementation of integrated project delivery methods from the demand side, the social housing organisation. However, it has been also identified that the use of integrated project delivery methods have consequences for the supply side actors. Especially for the architect because his central role in the design process could be affected. This study, which is based on the analysis of the role of the architect in thirteen renovation projects that used integrated contracts, concludes that the main role of the architect, as having principal responsibility for the design choices made, does not change when integrated contracts are used. However, the decision-making power of the architect does decrease. With the use of integrated contracts, the main contractor and some specialised contractors can also influence the design choices – an influence that they would not otherwise have. In cases where the main contractor plays an active leading role in the consortium, the reduction of the decision-making power of the architect may become even more evident, and in the opinion of some architects, turn the role of architect into a role more akin to that of technical and aesthetic advisor. The changes in how design decisions are taken do not have a negative impact on the quality of the relationship between the architect and the SHO, and has a positive influence on the quality of the relationship between the architect and the construction companies involved in the project. Some changes were reported relating to the workload for each project compared to Design-Bid-Build projects. In some cases, architects were no longer involved in project management tasks, while in other cases architects were assigned additional responsibilities, such as communicating with tenants. It is not possible, therefore, to establish a direct relationship between the use of integrated contracts and the size of the architect’s workload.Where there is an evident change is in the

    This comprehensive final report for the Swiss Federal Office of Energy (SFOE) presents the results of a study that examined the question of building renewal in Switzerland - should one rebuild or renovate? The report first examines the age-profile of Swiss buildings, defines renewal strategies and ideas, looks at renewal cycles and, in the light of future renewal demands, describes scenarios for replacement with new buildings instead of carrying out total renovations. The housing owners and their methods of management for multiple-apartment housing are described and the various factors involved in making decisions on how to renovate are discussed from the technical, legal and fiscal points of view. The report goes on to examine the ecological and energy aspects of renewal, presenting figures on energy consumption and material flows. Building renewal is also discussed from the social and regional planning points of view. The report is concluded with a discussion on rebuilding or renewal that takes current renewal deficits, costs and social aspects into account and makes recommendations for further action. An appendix presents renewal case studies.

The conducted experiments were aimed at analyzing partitions of 120 mm brick mounted gypsum panels while other walls were 520 mm thick and plastered on both sides. Under natural conditions, sound insulation factors of facades were measured and compared according to comfort classes. The obtained results revealed that thick brick walls of 520 mm insulated the sound of 58 decibels (dB (class B. In contrast, 120 mm brick masonry partition reduced sound only to 48 dB which is class E and agrees with the lowest class of sound insulation. We also calculated the sound insulation factor applying three formulas considering the mass law of sound insulation and comparing it with other previous studies.

    The installation or renovation of a cleanroom is an increasing priority among compounders who, to offer sterile preparations, must comply with the most recent version of United States Pharmacopeia revised General Chapter 797 guidelines. To upgrade their pharmacy facilites, many compounders have worked successfully with a large-scale mechanical engineering firm or a specialized construction company dedicated to cleanroom installation. However, a qualified local mechanical contractor with design capability is a valuable and often overlooked resource for the construction of customized stae-of-the-art cleanrooms. In this report, we describe the installation of such a facility in a busy pharmacy and suggest ways in which compounding pharmacists can identify competent local contractors and control the cost of construction and upgrades. The addition of a cleanroom has enabled The Compounding Pharmacy in Hickory, North Carolina, to achieve accreditation from the Pharmacy Compounding Accreditation Board.

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Due to pollution in second water supply system (SWSS), nine renovation alternative plans were proposed and comprehensive evaluations of different plan based on Analytical Hierarchy Process (AHP) were presented in this paper. Comparisons of advantages and disadvantages among the plans of SWSS renovations provided solid foundation for selecting the most appropriate plan for engineering projects. In addition, a mathematical model of the optimal combination of renovation plans has been set up and software Lingo was used to solve the model. As a case study, the paper analyzed 15 buildings in Tianjin City. After simulation of the SWSS renovation system, an optimal scheme was obtained, the result of which indicates that 10 out of those 15 buildings need be renovated in priority. The renovation plans selected for each building are the ones ranked higher in the comprehensive analysis. The analysis revealed that the optimal scheme, compared with two other randomly calculated ones, increased the percentage of service population by 19.6% and 13.6% respectively, which significantly improved social and economical benefits.

  2. Neural Pathway of Renovative and Innovative Products Appreciation

    Huang, Furong; Chiu, Chiyue; Luo, Jing

    2016-12-01

    According to the level of change an invention makes on existing things and how it overrides people’s mental schemas on established categories, new inventions can be classified into two groups: incremental inventions (i.e., renovations), which make minor improvements on existing designs, and radical inventions (i.e., innovations), which make major developments that enable people to do things they have never been able to do before. Although innovation and renovation are two fundamentally different types of creation that feature new changes ranging from those in product development to those in large scale social changes, and people tend to report higher subjective preferences for incremental inventions compared to radical inventions, the cognitive brain mechanisms underlying the mental representation of these two types of inventions remains unknown. Through the use of innovative and renovative designs as materials, we found that relative to non-creative designs, creative (renovative &innovative) designs enhanced memory or association-related activation in the right parahippocampus. In particular, innovations evoked more activation in the conceptual pathway for representing objects than did renovations, whereas renovations evoked more activation in the motor pathway than innovations. These results suggest that operating experiences may provide advantages for understanding and appreciating creative designs.

  3. The building stock from perspective of change - renovation roadmap

    Energy Technology Data Exchange (ETDEWEB)

    By 2050, population, society and economic structures will have changed several times. The long and short-term goals and objectives concerning our built environment are mutually contradictory. Determining objectives or creating scenarios for the future built environment is fruitless. We should approach the development of the built environment from the perspective of change and improve the flexibility and adaptability of the built environment. For the users, a built environment meeting their basic needs is part of sustainable development. Identified short-range renovation needs include eliminating damp and mould problems, improving energy and eco-efficiency, removing obstacles to mobility and adapting buildings to accommodate the needs of the elderly. Vacated areas and buildings should be recycled and offered a new life supporting a sense of community and service production. Improved energy efficiency reduces greenhouse gas emissions. Instead of renovating individual buildings, renovation of the entire area is recommended. Sustainability in construction translates into favouring recycling and renewable materials and building-specific energy systems using renewable and/or low-emission resources. It is recommended that renovations to improve energy efficiency are scheduled to coincide with other maintenance/ renovations so as to reduce costs. In renovation construction, the role of service improvement is more important than products. Improved services help to identify a solution that fulfils several customer needs, meets financial limitations and can be implemented efficiently. Companies are advised to view renovation construction as an innovative market segment entitled to its own service portfolio. Truths about new building should be discarded and new services developed based on recent study results and new technologies. (orig.)

    Otitis media (OM) is a common infection in early childhood with repeated attacks that lead to long-term complications and sequelae, but its risk factors still remain unclear. To examine the risk of childhood OM for different indoor and outdoor air pollutants during different timing windows, with a purpose to identify critical windows of exposure and key components of air pollution in the development of OM. We conducted a retrospective cohort study of 1617 children aged 3-4 years in Changsha, China (2011-2012). Children's life-time prevalence of OM and exposure to indoor air pollution related to home renovation activities were surveyed by a questionnaire administered by the parents. Children's exposure to outdoor air pollution, including nitrogen dioxide (NO2), sulfur dioxide (SO2), and particulate matter with an aerodynamic diameter ≤ 10 μm (PM10), was estimated using the measured concentrations at municipal monitoring stations. The odds ratio (OR) and 95% confidence interval (CI) of childhood OM for prenatal and postnatal exposure to indoor and outdoor air pollution were examined by using logistic regression model. Life-time prevalence of OM in preschool children (7.3%) was associated not only with prenatal exposure to industrial air pollutant with adjusted OR (95% CI) = 1.44 (1.09-1.88) for a 27 μg/m(3) increase in SO2 but also with postnatal exposure to indoor renovations with OR (95% CI) = 1.62 (1.05-2.49) for new furniture and 1.81 (1.12-2.91) for redecoration, particularly in girls. Combined exposure to outdoor SO2 and indoor renovation significantly increased OM risk. Furthermore, we found that exposure to outdoor SO2 and indoor renovation were significantly associated with the onset but not repeated attacks of OM. Prenatal exposure to outdoor industrial air pollution and postnatal exposure to indoor renovation are independently associated with early childhood OM in China and may cause the OM onset.

    Heating of dwellings represents a major policy challenge for the transition to a low carbon society. In Denmark, heating of dwellings represents about 25% of the total Danish final energy consumption and about 13% of the total CO2 emission. The majority of this is related to heating of older dwellings, and as the rate of replacement is low, the main potential for energy saving is to improve the energy efficiency of the existing dwelling stock through energy renovation. This paper provides an analysis of Danish experiences with energy labels (also known as the Energy Performance Certificate, EPC), which indicate the energy efficiency of buildings and include recommendations for improvements. The aim of the EPC is to motivate homeowners to do energy improvements. In Denmark, energy audit schemes date back to the early 1980s and energy rating of houses (energy labelling) was introduced in 1997. The long history of energy audit schemes and energy labelling makes Denmark an interesting case for the study of the experiences with and impact of this kind of policy measure. With the EU Energy Performance of Buildings Directive (EPBD) from 2002, an energy labelling scheme similar to the Danish scheme introduced in 1997 is now in use in all EU member states. The focus of this paper is on the homeowners' experience and use of the EPC and the key research questions are: How do the homeowners understand and use the EPC? Does the EPC have an influence on home energy renovation practices? The analysis is based on results from a survey of Danish homeowners who have purchased a home with an EPC within recent years. The Danish survey is part of the European project IDEAL EPBD, which was funded by the European Commission under the Intelligent Energy Europe programme and run from 2008 to 2011. The results indicate a rather limited influence of the EPC on Danish homeowners' home energy renovation practices. Also, the results show that even though most homeowners find the label

    DOE funding was used to renovate 4,500 square feet of aging laboratories and classrooms that support science, engineering, and mathematics disciplines (specifically environmental science, and computer engineering). The expansion of the labs was needed to support robotics and environmental science research, and to better accommodate a wide variety of teaching situations. The renovated space includes a robotics laboratory, two multi-use labs, safe spaces for the storage of instrumentation, modern ventilation equipment, and other “smart” learning venues. The renovated areas feature technologies that are environmentally friendly with reduced energy costs. A campus showcase, the laboratories are a reflection of the University’s commitment to the environment and research as a tool for teaching. As anticipated, the labs facilitate the exploration of emerging technologies that are compatible with local and regional economic plans.

    The Thacher School is in the process of renovating the campus observatory with a new meter class telescope and full automation capabilities for the purpose of scientific research and education. New equipment on site has provided a preliminary site characterization including seeing and V-band sky brightness measurements. These data, along with commissioning data from the MINERVA project (which uses comparable hardware) are used to estimate the capabilities of the observatory once renovation is complete. Our V-band limiting magnitude is expected to be better than 21.3 for a one minute integration time, and we estimate that milli-magnitude precision photometry will be possible for a V=14.5 point source over approximately 5 min timescales. The quick response, autonomous operation, and multi-band photometric capabilities of the renovated observatory will make it a powerful follow-up science facility for exoplanets, eclipsing binaries, near-Earth objects, stellar variability, and supernovae.

    From 2010 to 2012, librarians at the University of Florida Health Science Center Library (HSCL) used an online survey and focus groups to gather user input on preferences for an ideal library space. User input guided the HSCL's renovation plans and put a clear focus on enhancing technology, improving infrastructure, enabling group collaboration, and creating comfortable spaces. Additional communication with users during renovation was vital in ensuring continued usability of nonconstruction spaces and shared understanding of the construction timeline. While specific user suggestions are particular to the HSCL, overall themes and methods for eliciting input will be useful to other libraries undergoing space planning.

    This study sought to determine whether renovating low-income housing using "green" and healthy principles improved resident health and building performance. We investigated resident health and building performance outcomes at baseline and one year after the rehabilitation of low-income housing using Enterprise Green Communities green specifications, which improve ventilation; reduce moisture, mold, pests, and radon; and use sustainable building products and other healthy housing features. We assessed participant health via questionnaire, provided Healthy Homes training to all participants, and measured ventilation, carbon dioxide, and radon. Adults reported statistically significant improvements in overall health, asthma, and non-asthma respiratory problems. Adults also reported that their children's overall health improved, with significant improvements in non-asthma respiratory problems. Post-renovation building performance testing indicated that the building envelope was tightened and local exhaust fans performed well. New mechanical ventilation was installed (compared with no ventilation previously), with fresh air being supplied at 70% of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers standard. Radon was < 2 picocuries per liter of air following mitigation, and the annual average indoor carbon dioxide level was 982 parts per million. Energy use was reduced by 45% over the one-year post-renovation period. We found significant health improvements following low-income housing renovation that complied with green standards. All green building standards should include health requirements. Collaboration of housing, public health, and environmental health professionals through integrated design holds promise for improved health, quality of life, building operation, and energy conservation.

    With a special matter, Chinese literature has differences with traditional theories from western countries in essence, so that Chinese literature demonstrates its renovation and involution. The main reason is its trends of modernity. The transformation from oversea exchange is very important. This paper mainly explains the specific content of paradox of Chinese literature in mo-dernity, and explores the reasons for differences between China and western countries.

  5. On the Testing of Renovations Inside Historical Opera Houses

    2002-11-01

    Due to the large number of historical opera houses in Italy, many theatres have been renovated in the past, but still more will undergo major restoration in the near future. Unfortunately in this context, the quality and protection of acoustics is rarely considered as an issue of its own. As a consequence, the renovations are hardly ever accompanied by proper scientific and technical support. In this paper, the acoustical impact of works inside the Teatro Municipale "R.Valli" in Reggio Emilia, including the restoration of the main hall and the construction of a new acoustic shell, will be dealt with. Surveys were held in the theatre before renovation and were repeated with identical procedure and instruments after its completion. By means of a comparative analysis of the architectural project and of acoustical data, the impact of major changes in the theatre can be predicted. It is shown that this approach can help in drafting an operational scheme for safeguarding the acoustics of historical opera houses.

    The renovation work under way in the CERN Main Building should be completed by June. From the floors to the ceilings, everything has been done to give this historic building a new lease of life.     Taken in the early 60s, this picture illustrates how light maintenance was a challenge for the auditorium in CERN’s main building.   Nobody who has recently had to shimmy between the cables, ladders and toolboxes deposited around the main hall of Building 500 to get to the post office, the bank or Restaurant 1 can be oblivious to the fact that the ground floor of the Main Building has been getting a face-lift. The renovation work, which started with the first-floor concourse in June 2010, should be finished over the next couple of months. The first-floor renovations, now almost complete, set the tone for the rest of the project. The floor and ceiling, both fitted with special acoustic materials for efficient noise damping, have been completely refurbished and the Building ...

  7. Mean-field dynamo action in renovating shearing flows.

    2012-08-01

    We study mean-field dynamo action in renovating flows with finite and nonzero correlation time (τ) in the presence of shear. Previous results obtained when shear was absent are generalized to the case with shear. The question of whether the mean magnetic field can grow in the presence of shear and nonhelical turbulence, as seen in numerical simulations, is examined. We show in a general manner that, if the motions are strictly nonhelical, then such mean-field dynamo action is not possible. This result is not limited to low (fluid or magnetic) Reynolds numbers nor does it use any closure approximation; it only assumes that the flow renovates itself after each time interval τ. Specifying to a particular form of the renovating flow with helicity, we recover the standard dispersion relation of the α(2)Ω dynamo, in the small τ or large wavelength limit. Thus mean fields grow even in the presence of rapidly growing fluctuations, surprisingly, in a manner predicted by the standard quasilinear closure, even though such a closure is not strictly justified. Our work also suggests the possibility of obtaining mean-field dynamo growth in the presence of helicity fluctuations, although having a coherent helicity will be more efficient.

    Renovation of the control system of the CERN LHC injectors was initiated in 2007 in the scope of the Injector Controls Architecture (InCA) project. One of its main objectives was to homogenize the controls software across CERN accelerators and reuse as much as possible the existing modern sub-systems, such as the settings management used for the LHC. The project team created a platform that would permit coexistence and intercommunication between old and new components via a dedicated gateway, allowing a progressive replacement of the former. Dealing with a heterogeneous environment, with many diverse and interconnected modules, implemented using different technologies and programming languages, the team had to introduce all the modifications in the smoothest possible way, without causing machine downtime. After a brief description of the system architecture, the paper discusses the technical and non-technical sides of the renovation process such as validation and deployment methodology, operational applicatio...

    Many thousands of tonnes of asbestos were used in buildings in the past, especially for thermal insulation of pipes and boilers in power plants. Occupational exposure to asbestos dust now mainly occurs during demolition, renovation and routine maintenance activities. The objective of this study was to evaluate occupational exposure to airborne asbestos during renovation of solid oil-shale fuelled power plants carried out in 2001-2003. Air monitoring inside and outside of the renovation area was performed. The concentration of airborne fibres in the working environment increased during renovation but the valid limit value (0.1 fibres/cm(3)) was not exceeded.

  10. Analysis of the quality renovated continuous steel casting roller

    2013-06-01

    This paper presents the possibility of restoration of worn contact surfaces of rollers for continuous casting of steel. Permanent effort of steel producers to extend the lifespan of these components requires the implementation of new filler materials or modifying technological renovation processes to reduce the economic costs. This matter seems to be very important for the world leaders in steel production, e.g., ArcelorMittal, Tata Steel, but also for smaller concerns such as Magnitogorsk Iron and Steel Works, Salzgitter, etc. Renovation of continuous steel casting rollers, made of X12Cr13 EN 10088-1-97, was realised using submerged arc surfacing technology. Worn surface of roller was machined and surfaced using one interlayer and two cover layers. The quality of deposited layers was verified using non-destructive and destructive tests. The influence of filler material on the tribological properties of contact surfaces of deposited layers was analysed by abrasive wear test. Studies were made in the influence of surfacing parameters on cladding metal mixing (mixed) with base metal and also influence of heat introduced by welding using metallographic analysis. The experiments confirmed very good wear resistance of the applied filler metal due to dispersion strengthening caused by finely dispersed carbides and nitrides in the weld coating. The measures to be taken into account in renovation of rollers using hard surfacing, as well as the development of research in this area were also given. The experiments have confirmed that parameters used are suitable for studying filler materials.

    The solar energy manifests itself in different forms and its application has been fundamental for the humankind development. These forms are known as renewable energies, since they are energy forms that are renewed or remade with time or that are so abundant on Earth, that they will last for hundreds or thousands of years, either we use them or not. The main advantage of the utilization of the renewable energies in comparison with hydrocarbons is the one of having smaller impact on the environment, which brings about the conservation of nonrenewable resources, and to postpone its exhaustion. They allow the distributed generation, diminishing the power losses in the transmission and distribution systems, which increases the overall efficiency. In addition they can be the drive for regional development and generation of employment, because when having applications in remote zones and being a field still not completely developed in Mexico, the possibility exists of enabling professionals and technicians. From the point of view of the power sector, the renewable energies extend the supply and availability of energy, making more flexible and independent the operation and reliability of the national power system. [Spanish] La energia solar se manifiesta de diversas formas y su aplicacion ha sido fundamental para el desarrollo de la humanidad. A estas formas se les conoce como energias renovables, ya que son formas de energia que se van renovando o rehaciendo con el tiempo o que son tan abundantes en la tierra, que perduraran por cientos o miles de anos, las usemos o no. La principal ventaja del aprovechamiento de las energias renovables en comparacion con los hidrocarburos es la de tener menor impacto al medio ambiente, lo que trae consigo la conservacion de recursos no renovables, y posponer su termino. Permiten la generacion distribuida, disminuyendo las perdidas energeticas en los sistemas de transmision y distribucion, lo que incrementa la eficiencia general. Ademas

  2. Decreasing emission factor of pollutants in an oil refinery by renovating the furnace design

    Directory of Open Access Journals (Sweden)

    A. Zabihi

    2016-05-01

    Full Text Available The significant consumption of gas in the World results in the emission of greenhouse gases into atmosphere. Abadan refinery has always been the biggest and oldest oil refinery in the Middle East and has a variety of refined products. After six months of collecting data about pollutant concentration emitted from a stack of old furnaces of units 75 and new unit 200, the emission factor of the pollutant was calculated. The result showed that the emission factor of some hazardous pollutants emitted from old unit 75 was tremendously higher than that of unit 200. This study suggests the installation of a forced fan to provide the excess air and a feed temperature controlling system to control fuel gas consumption. These would make the fuel combustion complete and decrease its consumption. Meanwhile, further results showed that the renovation of unit 75 could lead to a significant annual reduction of some pollutants such as CO, H2S, and CxHx to 66 ton, 3 ton, and 800 kg, respectively; this would increase the emission rate of pollutant SO2 up to 150 ton annually. Finally, the new data of pollution coming from unit 75 were compared to pollution standard at American refineries. Results showed that the emission factor of most pollutants were below the American standard limits. However, the emission factor of sulfur dioxide emitted from upgraded furnace of unit 75 surpassed the American standard values. Fuel gas needs to be free of hydrogen sulfide in order to decrease SO2 emission in unit 75. It is predicted that the renovation of other 11 old furnaces belonging to Abadan refinery will result in significant decrease of pollutants CO, CxHx and H2S up to 320, 94 and 76 ton annually.

The report covers the renovation of a concrete office building in Copenhagen as an example. Here it has been proved that the studied measures, that have focused on the building envelope and ventilation and supply of renewable energy, split into two categories. Measures which focus on ventilation and utilization of solar energy in the form of both solar heat and solar cells lead to economic benefits. The insulation of the building envelope, however, is not economically attractive. Other measures like replacement of lighting systems have not been studied. (ln)

    Full Text Available The article marks out stages of planning of the moment of renovation, considers an algorithm of selection of the best variant of renovation out of alternative variants with consideration of such aspects as the degree of risk of each investment project, financial capabilities and economic efficiency of renovation. The article studies the scheme of analysis of alternative variants of technical and technological renovation, which includes preliminary, financial and economic, technical and other types of analysis. The article forms an economic model of assessment of introduction of a new technology at an enterprise moving by the technological scheme of development and realisation of novelty; it calculates expenses (engineering and design, material, technical and personnel training costs and identifies economic possibilities of an enterprise on the conduct of renovation. In the result it allocates the indicator of realisation of a new technology in general by an aggregate group of factors. Due to absence of indicators of assessment of efficiency of renovation adapted to market conditions, the article offers to calculate the indicator of assessment of efficiency of investing into renovation, showing what portion of the investment is returned in the form of profit during one period of planning.

    Plasmodium parasites, the causative agents of malaria, have developed elaborate strategies that they use to survive and thrive within different intracellular environments. During the blood stage of infection, the parasite is a master renovator of its erythrocyte host cell, and the changes in cell morphology and function that are induced by the parasite promote survival and contribute to the pathogenesis of severe malaria. In this Review, we discuss how Plasmodium parasites use the protein trafficking motif Plasmodium export element (PEXEL), protease-mediated polypeptide processing, a novel translocon termed the Plasmodium translocon of exported proteins (PTEX) and exomembranous structures to export hundreds of proteins to discrete subcellular locations in the host erythrocytes, which enables the parasite to gain access to vital nutrients and to evade the immune defence mechanisms of the host.

    2015-08-01

    Hospital construction and renovation activities are an ever-constant phenomenon in healthcare facilities, causing dust contamination and possible dispersal of fungal spores. We reviewed fungal outbreaks that occurred during construction and renovation over the last 4 decades as well as current infection prevention strategies and control measures. Fungal outbreaks still occur in healthcare settings, especially among patients with hematological malignancies and those who are immunocompromised. The causative pathogens of these outbreaks were usually Aspergillus species, but Zygomycetes and other fungi were occasionally reported. Aspergillus most commonly caused pulmonary infection. The overall mortality of construction/renovation-associated fungal infection was approximately 50%. The minimal concentration of fungal spores by air sampling for acquisition of fungal infections remains to be determined. Performing infection control risk assessments and implementing the recommended control measures is essential to prevent healthcare-associated fungal outbreaks during construction and renovation.

    Full Text Available Renovation of an existing building is an accomplished stem of the construction industry because it supplies financial diversification for construction stakeholders. Although several construction planning tools and stakeholder alignment exercises have been developed, no tool exists to assist project owners to decide between renovating an existing building and new construction with a comprehensive decision criteria. The objective of this research is to create and test a renovation versus new building support decision tool for construction project stakeholders. The renovation versus new building support decision tool was created based on an extensive review of existing support tools and construction industry needs. The created tool was implemented to evaluate decisions of educational facilities by university officials experienced in project management. Results show the tool was effective in identifying relevant topics for discussion and guiding a group of stakeholders through an exercise in decision-making. Specifically, the tool was implemented by construction management personnel for university facilities currently under construction to evaluate the decision to renovate an existing building or new construction. The main contribution of this research is a framework and support decision tool readily implementable for construction project stakeholders desiring to determine if renovation or new construction is the optimal path for their specific objectives.

    2013-12-01

    Full Text Available Environmental, commercial and societal developments in the Netherlands stimulate the environmental improvement of the existing office building stock. In the Netherlands, about 15% of all office area was vacant in 2012, and the majority of offices have a relative poor energy performance. To measure the improvement, different assessment tools are applied. These tools either focus on one aspect, such as operation energy, and result in a specific outcome such as MJ/m2, or these tools combine different aspects, such as energy and materials, through a weighted system and result in a generic outcome, such as ‘excellent’.In this research, the relation between assessment outcome and actual environmental impact is investigated of both types of tools, by reflecting the outcome of the tool to the carrying capacity of a system. The relation is investigated through a comparison of the energy and material aspect of three office façade renovation solutions using four different assessment tools. Using a tool in which energy and material impact is related to the carrying capacity, current energy focused optimization might lead to a sub optimization of actual environmental impact. To illustrate this, a calculated façade solution is presented with minimal environmental impact based on carrying capacity.

    Recolonization of enterococci, at a non-point source beach known to contain high background levels of bacteria, was studied after a full-scale beach renovation project. The renovation involved importation of new exogenous sand, in addition to infrastructure improvements. The study's objectives were to document changes in sand and water quality and to evaluate the relative contribution of different renovation activities towards these changes. These objectives were addressed: by measuring enterococci levels in the sand and fecal indicator bacteria levels (enterococci and fecal coliform) in the water, by documenting sediment characteristics (mineralogy and biofilm levels), and by estimating changes in observable enterococci loads. Analysis of enterococci levels on surface sand and within sediment depth cores were significantly higher prior to beach renovation (6.3-72 CFU/g for each sampling day) when compared to levels during and after beach renovation (0.8-12 CFU/g) (P < 0.01). During the renovation process, sand enterococci levels were frequently below detection limits (<0.1 CFU/g). For water, exceedances in the regulatory thresholds that would trigger a beach advisory decreased by 40% for enterococci and by 90% for fecal coliform. Factors that did not change significantly between pre- and post- renovation included the enterococci loads from animals (approx. 3 × 10(11) CFU per month). Factors that were observed to change between pre- and post- renovation activities included: the composition of the beach sand (64% versus 98% quartz, and a significant decrease in biofilm levels) and loads from direct stormwater inputs (reduction of 3 × 10(11) CFU per month). Overall, this study supports that beach renovation activities contributed to improved sand and water quality resulting in a 50% decrease of observable enterococci loads due to upgrades to the stormwater infrastructure. Of interest was that the change in the sand mineralogy also coincided with changes in biofilm

    In the present project a predesign for an energy efficient renovation of a multi storey housing in the city of Vejle has been developed. The project is based on the experiences from IEA Task 20 'Solar Energy in Building Renovation' and has been coordinated with the ongoing work of Task 20 regarding the development of new and improved concepts for the use of solar energy in building renovation. The key goals of the energy conscious design, which was developed through an integrated design process, are: Implementation of newly developed flexible facade concept, improved thermal comfort and air quality conditions, substantial energy savings, facade integration of solar energy components and design development through an integrated process. The main energy elements are: Usage optimised energy efficient glazed balconies, unventilated solar mass wall with transparent insulation, ventilated solar walls, convector integrated fresh air in-lets and demand controlled moisture regulated ventilation. Besides the energy related aspects, the project has focussed on logistical aspects of ecology and modular mass production. Therefore, also Life Cycle Cost analyses have been an important tool in the design phase. The energy demand for heating and ventilation is expected to be reduced by 50% compared to a standard renovation. The renovation has been implemented during 2000 and it is expected to be finished in the middle of 2002. (BA)

    What factors increase the chance that residents/owners in housing cooperatives agree on sustainable energy efficient renovation? Based on 30 qualitative interviews with professional advisors in cooperative housing associations and chairman/board and residents in three chosen case studies, an analysis of opportunities and barriers for making a common decision on renovation is performed. Success criteria and barriers are found on the societal level as well as on the organizational/individual level. The barriers and success criteria identified on the societal level are: knowledge level on energy-efficient renovation among relevant actors, owner structure of the housing cooperative, and existing regulations and incentives. On the organizational and individual level, the following categories influencing renovation processes were identified: the time frame and organization of the process, understanding the residents' needs, economy, the information given, and the existence of available exemplary projects and role models. Based on the results of the study, ten guidelines that contribute to more successful decision making processes and increase the chances of sustainable energy efficient renovation in housing cooperatives are presented.

    The aim of the DEMOHOUSE project is to develop minimum standards and recommendations for energy-efficient and sustainable renovation of social housing estates. Within this, the Decision Support Tool is one of the final results and uses knowledge gathered throughout the DEMOHOUSE project. In many European countries, social housing is owned by housing associations, municipalities or housing co-operations. To facilitate the decision makers in these organisations a simple instrument which helps to select relevant information for making decisions is developed within the DEMOHOUSE project. There are several phases in the process of renovation of dwellings. Main decisions in relation to ambitions of the renovation in energy-efficiency, sustainability, economic feasibility and occupants participation take place in the first so called initiative phase. It is this phase that the DST is focusing on to guide the decision makers, hosing managers and home owners associations alike, through decision making process towards achieving energy-efficient and sustainable renovation of dwellings. As any building renovation is a complex process with many stages, the tool also contains practical information and offers guidance and links to further more in-depth information of relevance to other stakeholders for example: architects, energy experts, building contractors, and building users.

    Heading for possible use for clinical trial, THOR (Tsing Hua Open-pool Reactor) at Taiwan was shutdown for renovation of a new epithermal neutron beam in January 2003. In November 2003, concrete cutting was finished for closer distance from core and larger treatment room. This article presents the design base that the construction of the new beam is based on. The filter/moderator design along the beam is Cd(0.1 cm)+Al(10 cm)+FLUENTAL{sup TM}(16 cm)+Al(10 cm)+FLUENTAL(24 cm)+Void(18 cm)+Cd(0.1 cm)+Bi(10 cm) with 6 cm Pb as reflector. Following the filter/moderator is an 88 cm long, 6 cm thick Bi-lined collimator with Li{sub 2}CO{sub 3}-PE at the end. The collimator is surrounded by Li{sub 2}CO{sub 3}-PE and Pb. The calculated beam parameters under 2 MW at the beam exit is phi{sub epi}=3.4x10{sup 9} n/cm{sup 2}/s, D{sub f}/phi{sub epi}=2.8x10{sup -11} cGy cm{sup 2}/n, D{sub {gamma}}/phi{sub epi}=1.3x10{sup -11} cGy cm{sup 2}/n, and J{sub +}/phi= 0.8. For a phantom placed 10 cm from beam exit, MCNP calculation shows that the advantage depth is 8.9 cm, and advantage ratio is 5.6 if boron concentration in tumor and normal tissue are assumed to be 65 and 18 ppm. The maximum dose rate for normal tissue is 50 cGy/min. The maximum therapeutic ratio is 6. The construction of the beam is scheduled to be finished by the end of April 2004.

    Temperate grasslands constitute over 30% of the Earth's naturally-occurring biomes and make an important contribution towards the partial mitigation of anthropogenic greenhouse gas emissions by terrestrial ecosystems. In permanent temperate grasslands, biomass production and sward quality can deteriorate over time and periodic renovation activities, involving soil tillage and reseeding, are commonly carried out to halt this decline. Long-term cultivation of agricultural land has been associated with soil aggregate degradation and reduced soil carbon storage. However, the impact of these single tillage disturbances on C cycling in grasslands is less clear. This study evaluated gaseous and dissolved organic carbon (DOC) losses following a single tillage event by subjecting grassland lysimeters with contrasting soil drainage characteristics to simulated conventional inversion or minimum tillage. Field-scale CO2 emissions after conventional tillage were also quantified and empirically modelled over short- and medium-term timeframes to delineate the ecosystem response to environmental variables. Soil moisture was the limiting determinant of ecosystem carbon release following conventional tillage. Freshly-tilled soils were associated with reduced water retention and increased sensitivity to soil moisture, which was particularly pronounced following rewetting events. Significantly elevated but ephemeral CO2 effluxes were detected in the hours following inversion ploughing, however tillage disturbance did not generate significantly enhanced C emission rates in the medium term. Equally, DOC losses were not significantly amplified by conventional tillage compared with conservative minimum tillage and were predominantly controlled by soil drainage across tillage regimes. Our results suggest that a net ecosystem source of 120 to 210 g C m-2 over an approximately two-month period was most likely a consequence of reduced productivity and C input rather than enhanced soil CO2

    2016-01-01

    In 1895, Percival Lowell hired eminent telescope maker Alvan G. Clark to build a 24-inch refractor. Lowell intended the telescope intitally for observing Mars in support of his controversial theories about life on that planet. Clark finished the telescope within a year and at a cost of $20,000. Lowell and his staff of assistants and astronomers began observing through it on July 23, 1896, setting off a long and productive career for the telescope.While Lowell's Mars studies dominated early work with the Clark, V.M. Slipher by the 1910s was using it to observe planetary rotations and atmospheric compositions. He soon revolutionized spectroscopic studies, gathering excruciatingly long spectra - some in excess of 40 hours - of the so-called white nebula and determining startling radial velocities, evidence of an expanding universe. In the 1960s, scientists and artists teamed up on the Clark and created detailed lunar maps in support of the Apollo program.In recent decades, the Clark has played a central role in the education programs at Lowell, with general public audiences, students, and private groups all taking advantage of this unique resource.With this nearly 120 years of contant use, the Clark had been wearing down in recent years. The telescope was becoming more difficult to move, old electrical wiring in the dome was a fire hazard, and many of the telescope's parts needed to be repaired or replaced.In 2013, Lowell Observatory began a fundraising campaign, collecting $291,000 to cover the cost of dome and telescope renovation. Workers removed the entire telescope mount and tube assembly from the dome, examining every part from tube sections to individuals screws. They also stabilized the dome, adding a water vapor barrier and new outer wall while reinforcing the upper dome. The project lasted from January, 2014 through August, 2015. The facility reopened for daytime tours in September, 2015 and evening viewing the following month.

    Full Text Available Captive African (Loxodonta africana and Asian (Elephas maximus elephants can experience foot pathologies and arthritis. As a preventative measure against these pathologies and to alleviate the potential discomfort due to concrete substrates, some zoological institutions have renovated elephant housing to increase the amount of natural or shock-absorbent substrates. The objective of this study was to compare behavioral (diurnal and nocturnal and glucorticoid (e.g., serum cortisol responses of three female African elephants before, during, and after renovation to their indoor housing floor to assess whether renovations had short-term effects on the elephants' behavior and stress physiology. Behavioral data were collected using scan-sampling methods, and activity budgets were constructed for each of the three elephants. In addition, the duration of all lying rest activities were recorded. Weekly serum cortisol concentrations were determined with enzyme immunoassay (EIA. Overall, eating was the most prevalent behavior exhibited outdoors during the day, while resting (either in a lying or standing position were most common during the indoor, nocturnal periods. Although variation existed among the three elephants, all three females spent significantly more time walking and less time eating during the day after the completion of the renovations. The extent to which the three elephants exhibited nocturnal lying rest behavior varied among the elephants, with the oldest elephant exhibiting the least amount (an average of 13.2 ± 2.8% of the nightly behavioral scans compared to the two younger elephants (an average of 34.5 ± 2.1% and 56.6 ± 2.8% of the nightly behavioral scans. There was a significant increase in lying rest behavior for one elephant and standing rest for a second elephant following renovations.

    2012-11-01

    The study estimates the feasible energy savings potential in the 2010 building stock by 2050. The focus is on energy-saving measures related to renovation of residential and service buildings. The calculations were done by building types and age groups using the EKOREM calculation model. The calculations indicate the building types and structural elements where potential for savings exists. The study did not consider energy-saving measures related to changes in heating systems, electrical equipment, property maintenance or use habits. The study disproved the common belief that considerably more energy savings could be achieved faster by focussing on the existing building stock instead of new construction. That is mainly due the fact that it generally pays to implement structural energy-saving measures only when the targeted elements also require other significant repairs besides energy-efficiency improvements. Thus, energy renovations cannot be speeded up very much. The clearest exception are the extra insulations added to roof assemblies that are easy to implement. Attempts to save more energy in the building stock than can be achieved at a small additional cost in connection with needed renovations may multiply costs, and the saving in energy costs will not necessarily cover the additional investments. The efficiency of energy-saving measures can be affected by recommending or ordering use of more energy efficient windows, thicker extra insulations or more efficient ventilation heat recovery systems than the standard solution selected in connection with renovations. The goal of preserving the characteristics of buildings of cultural-historical or architectural value and the typical solutions and materials used in all buildings of a certain period limit the repair and renovation of structural elements. In the case of these buildings, improvement of energy efficiency can be considered in connection with the planning of renovations and the buildings' use and

    Full Text Available Abstract Background Children in poor and minority neighborhoods often lack adequate environmental support for healthy physical development and community interventions designed to improve physical activity resources serve as an important approach to addressing obesity. In Denver, the Learning Landscapes (LL program has constructed over 98 culturally-tailored schoolyard play spaces at elementary schools with the goal to encourage utilization of play spaces and physical activity. In spite of enthusiasm about such projects to improve urban environments, little work has evaluated their impact or success in achieving their stated objectives. This study evaluates the impacts of LL construction and recency of renovation on schoolyard utilization and the physical activity rates of children, both during and outside of school, using an observational study design. Methods This study employs a quantitative method for evaluating levels of physical activity of individuals and associated environmental characteristics in play and leisure environments. Schools were selected on the basis of their participation in the LL program, the recency of schoolyard renovation, the size of the school, and the social and demographic characteristics of the school population. Activity in the schoolyards was measured using the System for Observing Play and Leisure Activity (SOPLAY, a validated quantitative method for evaluating levels of physical activity of individuals in play and leisure environments. Trained observers collected measurements before school, during school recess, after school, and on weekends. Overall utilization (the total number of children observed on the grounds and the rate of activity (the percentage of children observed who were physically active were analyzed. Observations were compared using t-tests and the data were stratified by gender for further analysis. In order to assess the impacts of LL renovation, recently-constructed LL schoolyards were

    Buildings account for a substantial part of the total energy consumption. In Denmark this number is about 40 % and this is approximately the same in most industrial countries. On this background there is an urgent need to develop strategies for reducing the energy demand in the building sector....... Renovation of existing buildings must have high priority as houses often last for 50 to 100 years, while the time perspective for the desired transformation to low-energy houses is less than 30 years in order to mitigate global warming and avoid irreversible tipping-points. The only sustainable energy supply...... investments in energy conservation measures with investments in the supply side, in order to avoid overinvestment in supply systems and thus to minimize the total costs of the transformation to Smart Energy Systems.

    Zirconia-based ceramics is widely used in dentistry. Different compositions of ceramics have different features. Our self-renovated ceramics become more machinable without scarifying its dental restoration properties after adjusting ratio of lanthanum phosphate (LaPO4)/yttrium oxide (Y2O3). In order to evaluate its safety, here, we tested its genotoxicity in primary human peripheral lymphocytes. The human lymphocytes cultured on three groups of different ratios of LaPO4/Y2O3 diphase ceramics for 6 days showed little effect of growth inhibition and similar effect of growth trend to the negative control. Furthermore, single-cell gel electrophoresis (comet assay) indicated that there was no significant difference of the value of tail moment between the tested ceramics and negative control, the IPS Empress II (P > 0.05). Our findings implicate that our self-renovated ceramics do not induce DNA damages in human peripheral lymphocytes and support their future clinic application.

    Samarin Oleg Dmitrievich

    2012-10-01

    Full Text Available The implementation of energy saving actions in the course of renovation of residential houses is considered by the author in the article. The need to change the mode of operation of heat supply systems and the employment of steam-gas co-generation power plants as a source of heat is demonstrated. Therefore, the problem of power saving in the course of renovation of residential houses comprises several constituents, and its resolution involves the implementation of a number of interrelated organizational and process-related actions. This is the only way to avoid conflicts and to reduce power consumption and losses at each stage of power generation and transmission absent of any deterioration of the internal microclimate in renovated premises. The implementation of the aforementioned actions will make it possible to convert to the automatic energy consumption reduction mode through the implementation of engineering solutions and without any immediate involvement of legal entities. This methodology may arouse the interest of both producers and consumers of thermal and electric energy.

    2011-06-01

    The paper discusses the background and results of research focused on the action of a high-speed water jet on concrete with different qualities. The sufficient and careful removal of degraded concrete layers is very important for the renovation of concrete structures. High-speed water jet technology is one of the most common methods used for removing degraded concrete layers. Different types of high-speed water jets were tested in the experimental part. The classical technology of a single continuous water jet generated with one nozzle was tested as well as the technology of revolving water jets generated by multiple nozzles (used mainly for the renovation of larger areas). A continuous flat water jet and pulsating flat water jet were tested the first time, because the connection of a water jet with the acoustic generator of a pulsating jet offers new possibilities for the use of a water jet (see [1] and [2]). A water jet with such a modification is capable of efficient action and can even be used for cutting solid concrete with a relatively low consumption of energy. A flat pulsating water jet which can be newly used for renovation seems to be a promising technology.

    The renovation of a building involves not just the fulfilment of functional requirements, but also considerations such as energy consumption, investment costs, environmental impact and wellbeing. As things stand, new design methods and tools are needed, and the aim of the research presented in this article was to develop a multicriteria tool, MultiOpt, for the optimization of renovation operations, with an emphasis on building envelopes, heating and cooling loads and control strategies. MultiOpt is based on existing assessment software and methods: it uses a genetic algorithm (NSGA-II) coupled to TRNSYS, and economic and environmental databases. This article illustrates its utilization in the renovation of a school in the southern French city of Nice which was representative of France's building stock. The study started with the monocriterion optimization of energy consumption, cost, thermal comfort, and life-cycle environmental impact. It then moved onto multicriteria optimizations. The monocriterion analyses focussed on the building's characteristics and performance; the multicriteria analyses were concerned with the interactions between the different objectives, and with identifying their convergences and divergences. The results demonstrated that MultiOpt can be used to compare different combinations of options and constraints, thus constituting a basis for operational decision-making. (author)

  1. A District Approach to Building Renovation for the Integral Energy Redevelopment of Existing Residential Areas

    Directory of Open Access Journals (Sweden)

    Mira Conci

    2017-05-01

    Full Text Available Building energy renovation quotas are not currently being met due to unfavorable conditions such as complex building regulations, limited investment incentives, historical preservation priorities, and technical limitations. The traditional strategy has been to incrementally lower the energy consumption of the building stock, instead of raising the efficiency of the energy supply through a broader use of renewable sources. This strategy requires an integral redefinition of the approach to energy building renovations. The joint project SWIVT elaborates on a district redevelopment strategy that combines a reduction in the energy demand of existing buildings and their physical interconnection within a local micro-grid and heating network. The district is equipped with energy generation and distribution technologies as well as hybrid thermal and electrical energy storage systems, steered by an optimizing energy management controller. This strategy is explored through three scenarios designed for an existing residential area in Darmstadt, Germany, and benchmarked against measured data. Presented findings show that a total primary energy balance at least 30% lower than that of a standard building renovation can be achieved by a cluster of buildings with different thermal qualities and connected energy generation, conversion, and storage systems, with only minimal physical intervention to existing buildings.

    The renovation of a building will certainly affect the quality of air in the vicinity of where associated activities were undertaken, this includes the quality of air inside the building. Indoor air pollutants such as particulate matter, heavy metals, and fine fibers are likely to be emitted during renovation work. This study was conducted to determine the concentration of heavy metals, asbestos and suspended particulates in the Biology Building, at the Universiti Kebangsaan, Malaysia (UKM). Renovation activities were carried out widely in the laboratories which were located in this building. A low-volume sampler was used to collect suspended particulate matter of a diameter size less than 10 μm (PM₁₀) and an air sampling pump, fitted with a cellulose ester membrane filter, were used for asbestos sampling. Dust was collected using a small brush and scope. The concentration of heavy metals was determined through the use of inductively coupled plasma-mass spectroscopy and the fibers were counted through a phase contrast microscope. The concentrations of PM₁₀ recorded in the building during renovation action (ranging from 166 to 542 μg m⁻³) were higher than the value set by the Department of Safety and Health for respirable dust (150 μg m⁻³). Additionally, they were higher than the value of PM₁₀ recorded in indoor environments from other studies. The composition of heavy metals in PM₁₀ and indoor dust were found to be dominated by Zn and results also showed that the concentration of heavy metals in indoor dust and PM₁₀ in this study was higher than levels recorded in other similar studies. The asbestos concentration was 0.0038 ± 0.0011 fibers/cc. This was lower than the value set by the Malaysian Department of Occupational, Safety and Health (DOSH) regulations of 0.1 fibers/cc, but higher than the background value usually recorded in indoor environments. This study strongly suggests that renovation issues need to be considered seriously

    Green eco-friendly housing includes approaches to reduce indoor air pollutant sources and to increase energy efficiency. Although sealing/tightening buildings can save energy and reduce the penetration of outdoor pollutants, an adverse outcome can be increased buildup of pollutants with indoor sources. The objective of this study was to determine the differences in the indoor air quality (IAQ) between green and non-green homes in low-income housing complexes. In one housing complex, apartments were renovated using green principles (n = 28). Home visits were conducted immediately after the renovation, and subsequently at 6 months and at 12 months following the renovation. Of these homes, eight homes had pre-renovation home visits; this allowed pre- and post-renovation comparisons within the same homes. Parallel visits were conducted in non-green (control) apartments (n = 14) in a nearby low-income housing complex. The IAQ assessments included PM{sub 2.5}, black carbon, ultrafine particles, sulfur, total volatile organic compounds (VOCs), formaldehyde, and air exchange rate. Data were analyzed using linear mixed-effects models. None of the indoor pollutant concentrations were significantly different between green and non-green homes. However, we found differences when comparing the concentrations before and after renovation. Measured immediately after renovation, indoor black carbon concentrations were significantly lower averaging 682 ng/m{sup 3} in post-renovation vs. 2364 ng/m{sup 3} in pre-renovation home visits (p = 0.01). In contrast, formaldehyde concentrations were significantly higher in post-renovated (0.03 ppm) than in pre-renovated homes (0.01 ppm) (p = 0.004). Questionnaire data showed that opening of windows occurred less frequently in homes immediately post-renovation compared to pre-renovation; this factor likely affected the levels of indoor black carbon (from outdoor sources) and formaldehyde (from indoor sources) more than the renovation status

    25% of US households utilize onsite wastewater treatment systems (OWTS) for wastewater management. Advanced technologies were designed to overcome the inadequate wastewater treatment by conventional OWTS in critical shallow water table areas, such as coastal zones, in order to protect ground water quality. In addition to the septic tank and soil drainfield that comprise a conventional OWTS, advanced systems claim improved water renovation with the addition of sand filtration, timed dosing controls, and shallow placement of the infiltrative zone. We determined water quality renovation functions under current water table and temperature conditions, in anticipation of an experiment to measure OWTS response to a climate change scenario of 30-cm increase in water table elevation and 4C temperature increase. Replicate (n=3) intact soil mesocosms were used to evaluate the effectiveness of drainfields with a conventional wastewater delivery (pipe-and-stone) compared to two types of pressurized, shallow narrow drainfield. Results under steady state conditions indicate complete removal of fecal coliform bacteria, phosphorus and BOD by all soil-based systems. By contrast, removal of total nitrogen inputs was 16% in conventional and 11% for both advanced drainfields. Effluent waters maintained a steady state pH between 3.2 - 3.7 for all technologies. Average DO readings were 2.9mg/L for conventional drainfield effluent and 4.6mg/L for advanced, showing the expected oxygen uptake with shallow placement of the infiltrative zone. The conventional OWTS is outperforming the advanced with respect to nitrogen removal, but renovating wastewater equivalently for all other contaminants of concern. The results of this study are expected to facilitate development of future OWTS regulation and planning guidelines, particularly in coastal zones and in the face of a changing climate.

    The built environment supports the safe care of patients in health care facilities. Infection preventionists and health care epidemiologists have expertise in prevention and control of health care-associated infections (HAIs) and assist with designing and constructing facilities to prevent HAIs. However, design elements are often missing from initial concepts. In addition, there is a large body of evidence that implicates construction and renovation as being associated with clusters of HAIs, many of which are life threatening for select patient populations. This article summarizes known risks and prevention strategies within a framework for patient safety.

    Full Text Available The use of steel bracings is possible in all four stages of engineering activities in the renovation and modernization of historic buildings, i. e.: protecting, repairing, strengthening and rebuilding. Steel bracings are auxiliary structural systems, which, due to their relatively small cross-section dimensions and low weight, provide an efficient way to achieve the required resistance and stability of the original historic building structural systems. The steel structure in most cases is the tissue that differs in style and material of genuine tissue which is present in a renewed historic building, but is also often a rational solution acceptable to the conservation and structural point of view.

    Highlights: ► We developed a waste estimation system leveraging the BIM technology. ► The system can calculate waste disposal charging fee and pick-up truck demand. ► We presented an example scenario demonstrating this system. ► Automatic, time-saving and wide applicability are the features of the system. - Abstract: Due to the rising worldwide awareness of green environment, both government and contractors have to consider effective construction and demolition (C and D) waste management practices. The last two decades have witnessed the growing importance of demolition and renovation (D and R) works and the growing amount of D and R waste disposed to landfills every day, especially in developed cities like Hong Kong. Quantitative waste prediction is crucial for waste management. It can enable contractors to pinpoint critical waste generation processes and to plan waste control strategies. In addition, waste estimation could also facilitate some government waste management policies, such as the waste disposal charging scheme in Hong Kong. Currently, tools that can accurately and conveniently estimate the amount of waste from construction, renovation, and demolition projects are lacking. In the light of this research gap, this paper presents a building information modeling (BIM) based system that we have developed for estimation and planning of D and R waste. BIM allows multi-disciplinary information to be superimposed within one digital building model. Our system can extract material and volume information through the BIM model and integrate the information for detailed waste estimation and planning. Waste recycling and reuse are also considered in our system. Extracted material information can be provided to recyclers before demolition or renovation to make recycling stage more cooperative and more efficient. Pick-up truck requirements and waste disposal charging fee for different waste facilities will also be predicted through our system. The results

    Due to the rising worldwide awareness of green environment, both government and contractors have to consider effective construction and demolition (C&D) waste management practices. The last two decades have witnessed the growing importance of demolition and renovation (D&R) works and the growing amount of D&R waste disposed to landfills every day, especially in developed cities like Hong Kong. Quantitative waste prediction is crucial for waste management. It can enable contractors to pinpoint critical waste generation processes and to plan waste control strategies. In addition, waste estimation could also facilitate some government waste management policies, such as the waste disposal charging scheme in Hong Kong.

  10. The Phenomenon of Trust in Flat Owners’ Collective Renovation Strategies in Estonia

    Directory of Open Access Journals (Sweden)

    Liis Ojamäe

    2015-12-01

    Full Text Available Mobilising fl at owners into renovating residential blocks in post-socialist countries has been a complicated process. Evidence from Estonia shows that the success of collective renewal strategies depends not only on economic issues but also on ways investments are organised and, signifi cantly, the relationship of trust between diff erent actors. The paper aims at conceptualising the issue of institutional trust upon the experience of urban housing renewal in Estonia. It is contended that trust is crucial for the joint decision-making in a block as well as for facilitating negotiations between fl at owners’ associations, local municipalities and market actors. The paper draws on three qualitative studies conducted in Estonia during the 2000s, which allow asserting that trust towards new strategies of housing renewal can be achieved and maintained by ‘best practices’, which by concentrating expert knowledge also denote direct communication between experts and fl at owners. While it is important to raise the residents’ technical knowledgeability, it is indispensable to develop abilities to manage and communicate the renovation process between diff erent parties. The public sector is conceived to be a central actor in sustaining trust between actors who have no previous positive experience from collective residential strategies

This is very difficult problem for biped and quadruped robot to realize a stable walking in the case that actuator or sensor is broken. And, in walking of mammal, gait pattern is generated by neural oscillator existing in the spinal cord. In the case that a lower neural system is injured, mammal realize a walking by a higher neural system. Thus, mammal has a self renovation function. In this study, in order to realize the stable walking of the quadruped robot with fault, we discuss the control method with self renovation function for the fault of the decentralized controller and the angular sensor. First, we design the centralized controller of one leg by sliding mode control for the fault of decentralized controller. Second, Sky Hook Suspension Control is applied for the fault of the angular sensor. The proposed methods are verified by 3D simulations by CAD and experiments. (author)

    A 602-bed capacity hospital underwent complete renovation from 1999 to 2004. In April 2005, the Infection Control Team was informed of the occurrence of three consecutive cases of Bacillus cereus bacteremia in a ward for patients with hematologic malignancies. A retrospective analysis of patients with Bacillus isolates was initiated. We found more Bacillus cereus isolates from blood samples in 2004 compare to the preceding years. Swab samples were collected in the particular ward from the surface of a working desk, filter unit of the air-conditioners, entrance of air inlet ducts, exit of the air outlet ducts and three-way valves of the particular ward under the consideration of iatrogenic contamination. Towels and gowns used in the ward were examined. Dens dust was noted in the filter of the air-conditioner and inlets/outlets of the air-ventilation system of the ward. Bacillus cereus was isolated from the dust, and from cleaned towels and gowns. PFGE fingerprinting differed among four patients' sample. We considered the present case as an undetected Bacillus cereus pseudo-outbreak that lasted for about one year after the renovation work of the hospital. We also considered that filters of the HVAC-system and towels and gowns were probable sources of the outbreak.

    Aiming at serious slag on the water wall around the burner of corner-fired boiler with low-ash-fusion-point coal, cold experimental model has been established. In this experiment, particle image velocimetry (PIV) has been employed to accurately measure aerodynamic field of burner region, and the experimental research of furnace slag renovation has been conducted through changing the burner jet arrangement. The experiment results show that it has significantly effect on aerodynamic field in the furnace by changing burner jet deflection angle. A reasonable actual tangential circle diameter can be formed through adjusting the burner jet deflection angle, to prevent primary air attacking the wall, and further more, to effectively prevent serious slag on the water wall around the burner.

    Questions of whether past nuclear regulatory body of Korea is not a proper system to monitor and check the country's nuclear energy policy and utilization have been raised. Moreover, a feeling of insecurity regarding nuclear safety after the nuclear accident in Japan has spread across the public. This has stimulated a renovation of the nuclear safety regime in Korea. The Nuclear Safety and Security Commission (NSSC) was launched on October 26, 2011 as a regulatory body directly under the President in charge of strengthening independence and nuclear safety. This was a meaningful event as the NSSC it is a much more independent regulatory system for Korea. However, the NSSC itself does not guarantee an enhanced public acceptance of the nuclear policy and stable use nuclear energy. This study introduces the new NSSC system and its details in terms of organization structure, appropriateness of specialty, budget stability, and management system. (authors)

  15. Energy Efficiency and Universal Design in Home Renovations - A Comparative Review.

    Science.gov (United States)

    Kapedani, Ermal; Herssens, Jasmien; Verbeeck, Griet

    2016-01-01

    Policy and societal objectives indicate a large need for housing renovations that both accommodate lifelong living and significantly increase energy efficiency. However, these two areas of research are not yet examined in conjunction and this paper hypothesizes this as a missed opportunity to create better renovation concepts. The paper outlines a comparative review on research in Energy Efficiency and Universal Design in order to find the similarities and differences in both depth and breadth of knowledge. Scientific literature in the two fields reveals a disparate depth of knowledge in areas of theory, research approach, and degree of implementation in society. Universal Design and Energy Efficiency are part of a trajectory of expanding scope towards greater sustainability and, although social urgency has been a driver of the research intensity and approach in both fields, in energy efficiency there is an engineering, problem solving approach while Universal Design has a more sociological, user-focused one. These different approaches are reflected in the way home owners in Energy Efficiency research are viewed as consumers and decision makers whose drivers are studied, while Universal Design treats home owners as informants in the design process and studies their needs. There is an inherent difficulty in directly merging Universal Design and Energy Efficiency at a conceptual level because Energy Efficiency is understood as a set of measures, i.e. a product, while Universal Design is part of a (design) process. The conceptual difference is apparent in their implementation as well. Internationally energy efficiency in housing has been largely imposed through legislation, while legislation directly mandating Universal Design is either non-existent or it has an explicit focus on accessibility. However, Energy Efficiency and Universal Design can be complementary concepts and, even though it is more complex than expected, the combination offers possibilities to advance

    Since September 2005, Charity Hospital of New Orleans has been closed due to Hurricane Katrina. A debate following the closing arose about whether this public hospital should be renovated or a new medical center affiliated with the Louisiana State University should be built. Using academic literature, government statistics, and popular press reports, we describe the economic implications that support the view that Charity Hospital should have been renovated. We also address why this policy was not pursued by demonstrating the influence politics and individual stakeholders (specifically, Louisiana State University) had on the eventual policy pursued. In this commentary we also note the political identity movement away from public-sector provision of services to private-sector interests.

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

    Full Text Available This article analyzes results of an unique experience of the Dao Wai historic district renovation project in Harbin of the 2010th. It includes an interpretation of the stylistic features of the Dao Wai building. Also, there was made a presumptive conclusion about the origins of the “Chinese Baroque”, which is now famous Dao Wai, combining European order architecture and far Eastern decorative tradition. Presumptive conclusion was based on the construction area observing in 2011-2016 and on the Chinese sources. As a result of renovation, there was formed a new public space with high tourism potential. Social value and status of the Dao Wai has significantly grown. The significant cost increase of real estate and provided services is an essential consequence of the gentrification method. There are were noted increased problems of the native people forced to move from the center to the outskirts of the city. Also, this article analyzes the current stage of the second phase design of Dao Wai renovation project and the perspectives for its implementation.

    The advanced spent fuel conditioning process facility (ACPF) of the irradiated materials examination facility (IMEF) at the Korea Atomic Energy Research Institute (KAERI) has been renovated to implement a lab scale electrolytic reduction process for pyroprocessing. The interior and exterior structures of the ACPF hot cell have been modified under the current renovation project for the experimentation of the electrolytic reduction process using spent nuclear fuel. The most important aspect of this renovation was the installation of the argon compartment within the hot cell. For the design and system implementation of the argon compartment system, a full-scale mock-up test and a three-dimensional (3D) simulation test were conducted in advance. The remodeling and repairing of the process cell (M8a), the maintenance cell (M8b), the isolation room, and their utilities were also planned through this simulation to accommodate the designed argon compartment system. Based on the considered refurbishment workflow, previous equipment in the M8 cell, including vessels and pipes, were removed and disposed of successfully after a zoning smear survey and decontamination, and new equipment with advanced functions and specifications were installed in the hot cell. Finally, the operating area and isolation room were also refurbished to meet the requirements of the improved hot cell facility.

    Negative pollution effects from atmospheric discharges by aluminium facilities exerted on population health can be traced by the parameters of the reproductive function in women, physical development of newborns, general and differential morbidity of children aged below one year as well as by anthropometric signs in birth, morbidity of children and adults, mortality, including due to oncology. The introduction of modern technologies including the preliminarily fire anode treatment and the use of highly effective methods of purification of industrial wastes cut the concentration (in atmospheric air) of anhydrous hydrogen fluoride and of solid fluorides as well as of aluminium to maximum permissible concentration; it also essentially reduced the content of benzapilene. A better atmospheric air observed yet in the course of renovation contributed to a lower morbidity of children, aged below one year, as well as to the prevalence of diseases affecting the eyes, respiratory and digestive organs, skin and subcutaneous cellular tissue; it also cuts the number of congenital anomalies versus the data obtained in a neighboring district.

    Maslow’s pyramid of human needs, proposed in 1943, has been one of the most cognitively contagious ideas in the behavioral sciences. Anticipating later evolutionary views of human motivation and cognition, Maslow viewed human motives as based in innate and universal predispositions. We revisit the idea of a motivational hierarchy in light of theoretical developments at the interface of evolutionary biology, anthropology, and psychology. After considering motives at three different levels of analysis, we argue that the basic foundational structure of the pyramid is worth preserving, but that it should be buttressed with a few architectural extensions. By adding a contemporary design feature, connections between fundamental motives and immediate situational threats and opportunities should be highlighted. By incorporating a classical element, these connections can be strengthened by anchoring the hierarchy of human motives more firmly in the bedrock of modern evolutionary theory. We propose a renovated hierarchy of fundamental motives that serves as both an integrative framework and a generative foundation for future empirical research. PMID:21874133

    The paper deals with analysis of welds-on quality of traverse crane wheels made from gr. 90–60 material, ASTM A148. Three types of welding-on technology with various filling materials were used. On wheel after wearing was welded-on one interlayer by a combination of additional materials, wire A 106 with F 11 addition and two cover layers made by a combination of A 508 wire with F 13 addition. Wheel surface was hardened after welding-on to a depth of 3 mm. A second welds-on technology was a combination of A 106 wire with F 11 addition. Two cover layers were made by a combination of RD 520 wire with F 56 addition. Third welds-on technology was realized to face one layer by C 113 wire in inert atmosphere: 80% Ar + 20% CO2. Two cover layers were made by wire with self protect Lincore 40-O. Properties of renovated traverse crane wheels were compared with the properties of new wheels with surface hardened layer. The welds-on were exposed to adhesive wearing where surface resistance was examined according to their weight loss. Influence of a particular element on the welds-on chemical composition was examined by EDX analyses.

  6. Thermal and Economic Analysis of Renovation Strategies for a Historic Building in Mediterranean Area

    Full Text Available Around 30% of the European building stock was built before 1950, when no regulations about energy efficiency were in force. Since only a small part of them has been renovated by now, the energy performance of this building stock is on average quite poor, resulting in a significant impact on the energy balance of European countries, as confirmed by data published by ISTAT (Italian National Statistical Institute. However, energy retrofit in historic edifices is a quite demanding issue as any intervention must take into account the need to preserve existing building materials and appearances while also allowing reversibility and low invasiveness. As an example, in these buildings it is not possible to apply an ETICS (External Thermal Insulation Composite System, since this would alter the historic and architectural value of the façade. On the other hand, internal insulation would have the drawback of reducing the net useful floor area, which also implies a loss of economic value. Moreover, internal insulation may induce overheating risks and mold formation. In this paper, all these issues are investigated with reference to an existing historic building located in southern Italy, showing that a retrofit strategy aimed at energy savings and cost-effectiveness is still possible if suitable materials and solutions are adopted.

    The aim of this article is to describe a set of participatory methods that we have either developed or modified for developing future work and service environments to better suit renewable rehabilitation processes. We discuss the methods in a larger framework of change process model and participatory design. Rehabilitation organizations are currently in transition; customer groups, financing, services, and the processes of rehabilitation centers are changing. The pressure for change challenges the centers to develop both their processes and facilities. There is a need for methods that support change management. Four participatory methods were developed: future workshop, change survey, multi-method assessment tool, and participatory design generator cards. They were tested and evaluated in three rehabilitation centers at the different phases of their change process. The developed methods were considered useful in creating a mutual understanding of the change goals between different stakeholders, providing a good picture of the work community's attitudes toward the change, forming an integrated overview of the built and perceived environment, inspiring new solutions, and supporting the management in steering the change process. The change process model described in this article serves as a practical framework that combined the viewpoints of organizational and facility development. However, participatory design continues to face challenges concerning communication between different stakeholders, and further development of the methods and processes is still needed. Intervention studies could provide data on the success factors that enhance the transformations in the rehabilitation sector.

    These Guidelines are intended to help current and future tenants of the Presidio work with designers and contractors to incorporate energy efficiency and sustainable practices into the renovations of the buildings. This guide is designed to complement the detailed Guidelines for Rehabilitating Buildings at the Presidio of San Francisco, available from the National Park Service. Energy efficiency yields benefits far beyond energy savings. Daylighting and efficient electric lighting, natural ventilation and cooling, and other conservation strategies improve tenant health, comfort, and productivity, while preserving the historical heritage of Presidio buildings. This guide examines the use of energy and resources and opportunities for efficiency in Presidio buildings on the basis of individual components and systems. The authors begin with recommended and discouraged practices for roofs, walls, and foundations, then move to windows and other opening. Next they address efficiency issues in building interiors--lighting, office equipment, and spacing planning. The authors follow with recommendations for mechanical and plumbing systems and conclude with insights on miscellaneous outdoor energy and resource concerns. A concise listing of sources of more detailed information is provided at the end of the document. The authors expect this guide to help tenants begin the process of using energy-efficient and sustainable practices throughout the Presidio of San Francisco.

    The purpose of this study was to evaluate the repair effects of chondrocytes that were cultured in vitro on osteoarthritis (OA). Chondrocytes were isolated from fetal rabbits and cultured in Biosilon microcarriers. Sixty rabbits were randomly divided into three groups equally (blank group, model group, treatment group). The rabbit knee OA model was established by inducing papain. Rabbits in the treatment group were injected with the chondrocytes that were cultured in vitro. Hematoxylin-eosin (HE) staining and gross morphologic observation were conducted. Expression level of cytokines such as IL-1bβ, IL-6, and TNF-α in cartilage synovial cells was also analyzed by an ELISA assay. The cultured chondrocyte was validated by a positive stain of type II collagen and vimentin by immunofluorescence. Compared to the model group, the articular cartilage of the rabbit knee in the treatment group showed a normal color, smooth surface, and none of malacia and coloboma. HE staining indicated that the articular surface of the treatment group tended to be smooth and flat; the matrix stained tinge and the cartilage destruction and fiber hyperplasia of the synovia were lightened. The expression levels of IL-1bβ, IL-6, and TNF-α also declined in the treatment group. OA symptoms were improved by treating with chondrocytes. In summary, the animal experiment in the present study indicated that chondrocyte injection played an active effect on renovation of OA.

  10. A Reflection on Low Energy Renovation of Residential Complexes in Southern Europe

    2016-09-01

    Full Text Available The transformation of European existing building stock towards very low energy buildings requires a new approach. In this context, it seems reasonable to think that buildings should no longer be renovated individually but as part of a global energy system. Focusing on larger urban units may present some scale advantages and may constitute an opportunity to change the urban environment in a smart energy way. Specificities of Southern European countries are addressed. Due either to the climate or the life style, there are large differences in energy consumption per dwelling among southern and northern European countries. How much heating energy will be saved by over-insulating building envelopes if people do not feel the need to heat their houses in the first place? In addition, real energy use in buildings frequently shows major differences with respect to the predicted consumption. The definition of realistic solutions demands the availability of realistic predictions. A case of a residential complex in Portugal is used to illustrate the main questions and to conclude that moving from a building to a group of buildings scale may be an interesting challenge for policy makers to look closer in the near future.

    The Nuclear Materials Storage Facility (NMSF) at the Los Alamos National Laboratory (LANL) was a Fiscal Year (FY) 1984 line-item project completed in 1987 that has never been operated because of major design and construction deficiencies. This renovation project, which will correct those deficiencies and allow operation of the facility, is proposed as an FY 97 line item. The mission of the project is to provide centralized intermediate and long-term storage of special nuclear materials (SNM) associated with defined LANL programmatic missions and to establish a centralized SNM shipping and receiving location for Technical Area (TA)-55 at LANL. Based on current projections, existing storage space for SNM at other locations at LANL will be loaded to capacity by approximately 2002. This will adversely affect LANUs ability to meet its mission requirements in the future. The affected missions include LANL`s weapons research, development, and testing (WRD&T) program; special materials recovery; stockpile survelliance/evaluation; advanced fuels and heat sources development and production; and safe, secure storage of existing nuclear materials inventories. The problem is further exacerbated by LANL`s inability to ship any materials offsite because of the lack of receiver sites for mate rial and regulatory issues. Correction of the current deficiencies and enhancement of the facility will provide centralized storage close to a nuclear materials processing facility. The project will enable long-term, cost-effective storage in a secure environment with reduced radiation exposure to workers, and eliminate potential exposures to the public. It is organized into seven parts. Part I - Design Concept describes the selected solution.

    The code REX [H.C. Kaufmann and K.R. Akselsson, Adv. X-ray Anal. 18 (1975) 353] and its successor, HEX were developed at Florida State University and University of Lund in the early seventies for quantitative reduction of PIXE spectra. HEX modelled many of the physical processes, including target self-absorption. Lack of adequate documentation and several inherent software related problems hampered widespread adoption and further development. HEX was designed using a hierarchical functional design approach, coded in FORTRAN IV. Its element library and request list are tightly constrained. ANSI standard FORTRAN provides few structured constructs, nor does it support dynamic data structures. HEX has a batch mode of interaction which affords minimal (interim) user interactions. To overcome these limitations we have modernised the program to run on IBM PC compatible computers by using object-oriented design techniques, documented in Program Description Language (pseudo-code) and implemented in a modern programming language, Pascal. Turbo Pascal 5.5 provides an integrated program development environment, a high resolution graphics library, an operating system interface and many software development tools to improve programmer productivity. A menu-based highly interactive screen management library is used for the user interface. A demonstration version is available for user evaluation. Further rigorous testing and the development of user acquired spectra interfacing code will be developed before the first release. The renovated code, WITS-HEX, has extracted the intellectual value embodied in HEX. It will be inherently more stable, reliable, versatile, maintainable and easy to use to facilitate future process modifications.

    The JOIDES Resolution (JR) has conducted 121 scientific drilling expeditions during the Ocean Drilling Program (ODP) and the first phase of the Integrated Ocean Drilling Program (IODP) (1983-2006). The vessel and scientific systems have just completed an NSF-sponsored renovation (2005-2008). Shipboard analytical systems have been upgraded, within funding constraints imposed by market driven vessel conversion cost increases, to include: (1) enhanced shipboard analytical services including instruments and software for sampling and the capture of chemistry, physical properties, and geological data; (2) new data management capabilities built around a laboratory information management system (LIMS), digital asset management system, and web services; (3) operations data services with enhanced access to navigation and rig instrumentation data; and (4) a combination of commercial and home-made user applications for workflow- specific data extractions, generic and customized data reporting, and data visualization within a shipboard production environment. The instrumented data capture systems include a new set of core loggers for rapid and non-destructive acquisition of images and other physical properties data from drill cores. Line-scan imaging and natural gamma ray loggers capture data at unprecedented quality due to new and innovative designs. Many instruments used to characterize chemical compounds of rocks, sediments, and interstitial fluids were upgraded with the latest technology.

    2016-03-01

    Full Text Available The objective of this article is to develop and apply a specific discounting cash flow (DCF approach to evaluate investment in renovation to improve building quality, thus increasing energy efficiency. In this article, we develop and apply a specific net present value (NPV and an internal rate of return (IRR approach to quantify the value created for the owners of the building by the investment in renovation via energy-saving investments that produce positive externalities. The model has an applied interest because, in recent years, a lot of investments in real estate were made by owners in order to increase the green quality of the buildings, and several funds of public aid were provided by the government to stimulate these energy-saving investments. The model proposed here is applied to a case study of a 16-apartment building located in northern Italy considers the model attempts to quantify the initial investment value, the energy savings, the tax deduction of the initial investment and the terminal value of the investment as the increase in building value. The analysis shows that the model is consistent in evaluating investments to improve building quality, and investments within the context of the specific case study considered in the research have IRRs ranging from a minimum of 4.907% to a maximum of 12.980%. It could even be useful to consider a sample of cases to verify whether our results are representative of this specific case study. The model could represent a useful tool for consumers in evaluating their own investments in building renovation, from a stand-alone perspective and even by comparing them with other types of investment. The research could be developed in the future to quantify the social welfare generated by public spending via tax deductions to reduce the costs of investment in energy savings for buildings and could even be applied to new real estate projects in comparing different construction technologies and even

    2007-01-01

    Major renovations were carried out in occupied dementia care units at the Lodge at Broadmead, Victoria, British Columbia. A 32-bed lodge was divided into two, requiring the relocation of three sets of doors. Home-like kitchens and living and dining rooms were built and furnished in each unit. A silent resident call system was installed. Nursing stations were moved off the unit. Murals added atmosphere and camouflaged exit doors. The process, while challenging, was successful due to comprehensive planning, careful phasing, the contractor's daily presence, the education of construction workers about residents, constant communication among key people and cooperation of lodge staff. Preliminary results are positive.

    2010-08-15

    The project has aimed to develop methods and examples related to the design of energy extensive renovations (low energy class 1), thereby stimulating energy conservation and increased use of renewable energy in existing buildings. This report is based on analysis of a specific type of school building from the 1970s on how it is technically and economically feasible to implement an extensive energy renovation. The survey shows that no single approach is able to bring the building's energy consumption down to BR08 (building code 2008) level. The study also shows that to achieve the BR08's low energy class one level, it is necessary to use a solar heating system. Economic calculations show that 12 out of 15 proposed energy-saving measures are economically viable. With longer lifetimes than specified in BR08 largely all actions are profitable. This profitability of most of the actions depends on some of the investment being considered as general maintenance or as a measure that also improves comfort and indoor climate. (ln)

    2014-01-01

    Human factors analyses have been used to improve efficiency and safety in various work environments. Although generally limited to humans, the universality of these analyses allows for their formal application to a much broader domain. This paper outlines a model for the use of human factors to enhance zoo exhibits and optimize spaces for all user groups; zoo animals, zoo visitors, and zoo staff members. Zoo exhibits are multi-faceted and each user group has a distinct set of requirements that can clash or complement each other. Careful analysis and a reframing of the three groups as interdependent coworkers can enhance safety, efficiency, and experience for all user groups. This paper details a general creation and specific examples of the use of the modified human factors tools of function allocation, operational sequence diagram and needs assessment. These tools allow for adaptability and ease of understanding in the design or renovation of exhibits.

    Full Text Available Among the multiple possible interventions on historical and consolidated urban contexts, two different approaches are the most diffused today: interpreting the project as a discontinuity with the surrounding environment, on one side, and reading it as a form of continuity with the existing fabric, on the other. Starting from these methods and through the analysis of the international state-of-the-art in the field of adaptive reuse, the article explores the opportunities of a third possible direction, resulting as synthesis of the above and showing different levels of controlled densification. This new language seems particularly suitable today for supporting deep renovation processes of existing and historic buildings, thanks to its ability of enhancing their tangible and intangible values.

    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

    To determine whether lead-containing shields have lead dust on the external surface. Institutional review board approval was obtained for this descriptive study of a convenience sample of 172 shields. Each shield was tested for external lead dust via a qualitative rapid on-site test and a laboratory-based quantitative dust wipe analysis, flame atomic absorption spectrometry (FAAS). The χ(2) test was used to test the association with age, type of shield, lead sheet thickness, storage method, and visual and radiographic appearance. Sixty-three percent (95% confidence interval [CI]: 56%-70%) of the shields had detectable surface lead by FAAS and 50% (95% CI: 43%-57%) by the qualitative method. Lead dust by FAAS ranged from undetectable to 998 μg/ft(2). The quantitative detection of lead was significantly associated with the following: (1) visual appearance of the shield (1 = best, 3 = worst): 88% of shields that scored 3 had detectable dust lead; (2) type of shield: a greater proportion of the pediatric patient, full-body, and thyroid shields were positive than vests and skirts; (3) use of a hanger for storage: 27% of shields on a hanger were positive versus 67% not on hangers. Radiographic determination of shield intactness, thickness of interior lead sheets, and age of shield were unrelated to presence of surface dust lead. Sixty-three percent of shields had detectable surface lead that was associated with visual appearance, type of shield, and storage method. Lead-containing shields are a newly identified, potentially widespread source of lead exposure in the health industry. Copyright © 2016 American College of Radiology. Published by Elsevier Inc.

    Energy savings are still the best form of alternative energy. While newly-built houses generally meet at least the heat loss protection codes for wintertime, the thermal improvement of the old building stock is a nation-wide economically relevant energy conservation, despite the fact that modern user habits and demands enforce such measurements anyway. However, the old construction is to be changed only asmuch as no damages can occur. New heating systems, insulation between the rafters in the roof section, additional insulation of the basement ceiling, and above all, heat-loss-protected and air-tight windows often lead to surface condensation and mould formation on the walls. If the outside wall is to be insulated, but the facade to be kept in its original appearance, then only an interior insulation is possible for a thermal retrofitting. The main goal of this project is to realise the idea of a gently capillary active inside insulation without additional vapour barrier for a reference building, to control it with measurement technology over a period of at least two winter- and summertimes, and to quantify the heat- and moisture content by means of a numerical simulation. As specific object with a worth-preserving facade for the application of the above-mentioned inside insulation was chosen, together with the City Redeveloping Association Dresden, a typical 'Gruenderzeit'-apartment house, built 1895 in Dresden-Neustadt, and extensively renovated from 1995 to 97. The main emphasis of the thermal retrofitting lies in the application of a 30 mm strong Calcium-Silicate slab along the inside of the exterior wall of the street facade. This wall made of brick is covered with square sandstone blocks all over the ground level and covered with a clinker layer typical for that time. With this project, the proof of a thermally sufficient and hygrically unproblematic retrofitting of an old building structure by means of inside insulation is given, and the foundation

However, silicone rubber is easy to get aged under the influence of surface discharge and corona discharge. After a certain duration of years'running, several phenomena will appear in the silicone rubber composite bushings, such as less hydrophobic, embrittling, chalking, cracking and other degradation, which will result in performance degradation of electrical insulation, and eventually leads to the grid accidents and high-voltage power equipment faults. When silicone rubber composite bushing is aging, the common approach is to replace by a new one, but this method is time consuming, laborious and expensive.

    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. The result reveals that the system performs well and its solutions are more successful than the actions undertaken by decision-makers. This system can improve traditional hospital building condition assessment while making it more effective and efficient.

    The project for the erection of a windmill park and the renovation/modernisation of the hydro power plants reached with the finishing of the pre-investigation a milestone. The results of the investigations show that the project is fully corresponding with both EU and polish politic aims of increased utilisation of renewable energy sources for electricity production. Further the pre-investigation notified, that in Poland there exists a lack of experience of the utilisation of wind for electricity production, as there exists only 12 windmill/windmill parks, so that the project is evaluated to have a high demonstration effect on the production of renewable energy based on wind. During the pre-investigation there were elaborated among others feasibility studies on the erection of the windmill park and the renovation of the hydro power plants. The economic feasibility calculations on both parts of the project, found that erection of the windmill park and the renovation of the hydro power plants are fully feasible under the existing conditions. It is foreseen that KEW, the local electricity production company as investor will obtain a loan under the Danish environmental soft loan program for Eastern Europe for the equipment and installation of the equipment. Associated specialist work is applied for support by the Danish Environmental Agency and the Danish Energy Agency. That these institutions and the Danish State Export Credit Agency (EKF) approve their principal willingness to support this project is the next necessary step for the projects implementation. (au)

    The building of the Nowa Sól public library is located on Bankowa Street, in the Lubuskie Voivodeship. The new seat of the library has been here since 2011; it had previously been located in the building on Parafialna and Szkolna Streets, which did not comply with the requirements of a comfortable library and reading room. Renovations and reconstructions of this neoclassical building began in 2007 and took four years to finish. Over the years, the century- old building had changed, its function - from a residential villa, to a children's hospital, and finally, a clinic for children. During construction works, rib and slab (Ackerman) floors were changed to concrete slabs with higher load-bearing strength and roof truss system replaced to accordingly to the original design. A new lift was built, and the library reading rooms and archives were expanded. The building also gained a new facade as well as new wooden windows and doors. The entire building is surrounded by a park.

    Full Text Available La gestión eficiente de ciertos recursos renovables caracterizados por la propiedad común y el libre acceso ha estado mediatizada por la denominada «Tragedia de los Comunes». La literatura pionera en este campo enfatizaba la necesidad de un marco regulatorio que superara esta tendencia hacia la sobreexplotación y agotamiento del recurso. Elinor Ostrom, sin embargo, en un trabajo seminal, se apartaba de esta línea y reivindicaba, paradójicamente, soluciones basadas en la propiedad y gestión comunal, que parecían estar en el origen del problema. El presente trabajo tiene, en este sentido, un doble objetivo. En primer lugar, realizar una revisión de la literatura económica sobre la explotación de recursos naturales en los espacios comunales y de libre acceso, con especial referencia al caso de la pesca. En segundo, y trascendiendo lo anterior, llamar la atención sobre el hecho de que la solución de Ostrom, que devuelve a la gestión del recurso su componente territorial y local, queda en el caso de la pesca fuertemente comprometida por un progreso tecnológico que está acabando con las pesquerías locales.

    Lead, which can be found in old paint, soil, and dust, has been clearly shown to have adverse health effects on the neurological systems of both children and adults. As part of an ongoing effort to reduce childhood lead poisoning, the US Environmental Protection Agency promulgated the Lead Renovation, Repair, and Painting Program (RRP) rule requiring that paint in target housing built prior to 1978 be tested for lead before any renovation, repair, or painting activities are initiated. This rule has led to a need for a rapid, relatively easy, and an inexpensive method for measuring lead in paint. This paper presents a new method for measuring lead extracted from paint that is based on turbidimetry. This method is applicable to paint that has been collected from a surface and extracted into 25% (v/v) of nitric acid. An aliquot of the filtered extract is mixed with an aliquot of solid potassium molybdate in 1 M ammonium acetate to form a turbid suspension of lead molybdate. The lead concentration is determined using a portable turbidity meter. This turbidimetric method has a response of approximately 0.9 NTU per microg lead per mL extract, with a range of 1-1000 Nephelometric Turbidity Units (NTUs). Precision at a concentration corresponding to the EPA-mandated decision point of 1 mg of lead per cm(2) is measurement using the new turbidimetric method, and the other half was analyzed using microwave extraction and measurement by ICP-AES. The average relative percent difference between the turbidimetric method and the ICP-AES method for the 24 sets measured as milligrams of lead per cm(2) is -0.63 +/- 32.5%; the mean difference is -2.1 +/- 7.0 mg lead per cm(2). Non-parametric and parametric statistical tests on these data showed no difference in the results for the two procedures. At the federal regulated level of 1 mg of lead per cm(2) paint, this turbidimetric method meets the performance requirements for EPA's National Lead Laboratory Accreditation Program (NLLAP

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

    Based on a concrete single-family house from the 70s it is investigated if it is technically and economically feasible to introduce extensive energy renovations of single houses from the 60s and 70s. The investigations show that it is not possible with one single action to bring the energy demand down to the level of BR08. In addition, the investigations show that it often is technically difficult to implement the proposed solutions and limited savings are often obtained for the single measures - eg. an increase in the insulation level of the floor is in the example difficult as the floor slab is bearing and the height of the rooms only allows for a small increase in the internal thickness of the insulation. The investigations show that in order to reach low energy class 1 level of BR08 energy production in the form of solar heating and/or pv is necessary. The economical calculations show that 7 out of 16 proposed single action are economically profitable. With a longer life time than indicated in BR08, another 3 actions becomes profitable. For most of the actions, profitability depends on the fact that part of the investment may be regarded as ordinary maintenance or a measure to increase comfort and indoor climate - so the entire investment does not have to be paid back through energy savings. Upgrading of the house to low energy class 1 of BR08 is not profitable no matter which of the three applied economical indicators are used. But if the house after all is being upgraded to the level of BR08 it is profitable to go all the way and future proof the house to low energy class 1. (LN)

    In June 2008, the Cedar River crested flooding more than 5,000 Cedar Rapids homes. Residents whose homes were flooded were invited to participate in this study. Household assessments and resident interviews were conducted between November 2008 and April 2009. We characterized exposures and symptoms experienced by individuals inhabiting 73 flood-damaged homes. Active air sampling and passive electrostatic dust collectors were used to assess exposures to: culturable mold, culturable bacteria, fungal spores, inhalable particulate matter (iPM), endotoxin, glucans, allergens, lead, asbestos, radon, carbon dioxide, and carbon monoxide. Wall moisture levels and relative humidity were also measured. Exposures and questionnaire-based health assessments were compared at two levels of remediation, in-progress and completed. Homes with remediation in-progress (n=24), as compared to the completed homes (n=49), had significantly higher airborne concentrations of mold, bacteria, iPM, endotoxin and glucan. Residents of in-progress homes had a significantly higher prevalence of doctor diagnosed allergies (adjusted OR=3.08; 95%CI: 1.05–9.02) and all residents had elevated prevalence of self-reported wheeze (adjusted OR=3.77; 95%CI: 2.06–6.92) and prescription medication use for breathing problems (adjusted OR=1.38; 95%CI: 1.01–1.88) after the flood as compared to before. Proper post-flood remediation led to improved air quality and lower exposures among residents living in flooded homes. PMID:22519834

    Full Text Available En este trabajo se analizan discursos del ámbito empresarial en los que se defienden propuestas ideológicas en el tema económico; en concreto, se analizan varios discursos en los que la Asociación Española de Productores de Energías Renovables (APPA, en adelante responde a las críticas vertidas desde determinadas multinacionales del sector de la energía por las subvenciones públicas otorgadas a las empresas de energías renovables, en particular a los productores de energía fotovoltaica. Los resultados del análisis (pragmático-discursivo y argumentativo revelan que el recurso principal que utiliza APPA para la defensa de este tipo de energías es la recontextualización de las críticas recibidas por parte de las multinacionales del sector de la energía, transformando estas críticas en una macroestrategia de deslegitimación de las energías renovables por parte de estas multinacionales. En el conjunto de los discursos analizados y del resto de estrategias argumentativas utilizadas, se puede observar, además, cómo esta deslegitimación es utilizada por APPA como prueba argumentativo-persuasiva para mostrar lo absurdo de tales críticas. Desde la perspectiva teórico-metodológica, este trabajo muestra la importancia en estos discursos de los recursos retóricoselocutivos; es decir, de aquellos capaces de activar marcos cognitivos determinados que evocan emociones, porque tanto transmiten intenciones como mueven a la acción.

Para reducir las producidas por el uso de gasóleo y electricidad, el proyecto europeo LIFE REWIND aborda el suministro desde fuentes renovables. Para ello, se ha caracterizado la demanda energética y recursos renovables en viñedo y bodega. Se ha buscado el diseño óptimo económico y medioambiental de la generación. Se ha instalado un prototipo en una explotación vitivinícola, con generación fotovoltaica, incluyendo un conjunto flotante sobre una balsa. Esto evita el uso de terreno, reduce la pérdida de agua de la balsa y mejora el rendimiento de los paneles fotovoltaicos. La electricidad producida alimenta la depuración de agua y el bombeo de riego por goteo del viñedo. Con la energía sobrante, un electrolizador produce hidrógeno mediante electrólisis del agua, que es utilizado por un vehículo todoterreno con pila de combustible. Los resultados muestran la viabilidad técnica y económica de los sistemas autónomos de energía renovable para alimentar el riego estacional en los viñedos. Así se evitan las extensiones indiscriminadas de la red y los grupos electrógenos diésel. Adicionalmente se muestra la posibilidad de reemplazar el gasóleo por electricidad o hidrógeno producido en la propia explotación.

    Many building-related health problems coincide with moisture damage and mold growth within a building. Their elimination is assumed to improve indoor air quality. The aim of this study was to follow the success of remediation in two individual buildings by analyzing the microbial flora and immunotoxicological activity of filter samples. We compare results from samples collected from indoor air in the moisture-damaged buildings before and after renovation and results from matched reference buildings and outdoor air. The microbial characteristics of the samples were studied by analyzing ergosterol content and determining the composition of fungal flora with quantitative polymerase chain reaction (QPCR). In addition, the concentrations of particles were monitored with optical particle counter (OPC). The immunotoxicological activity of collected particle samples was tested by exposing mouse macrophages (RAW264.7) for 24 h to particle suspension extracted from the filters, and measuring the viability of the exposed cells (MTT-test) and production of inflammatory mediators (nitric oxide, IL-6 and TNF*) in cell culture medium by enzyme-linked immunoassay (ELISA). The results show that for Location 1 the renovation decreased the immunotoxicological activity of the particles collected from damaged building, whereas no difference was detected in the corresponding samples collected from the reference building. Interestingly, only slight differences were seen in the concentration of fungi. In the Location 2, a decrease was seen in the concentration of fungi after the renovation, whereas no effect on the immunotoxicological responses was detected. In this case, the immunotoxicological responses to the indoor air samples were almost identical to those caused by the samples from outdoor air. This indicates that the effects of remediation on the indoor air quality may not necessarily be readily measurable either with microbial or toxicological parameters. This may be associated

    Residents in older homes may experience increased lead (Pb) exposures due to release of lead from interior paints manufactured in past decades, especially pre-1960s. The objective of the study was to determine the speciation of Pb in settled dust from an urban home built during WWII. X-ray absorption near-edge structure (XANES) and micro-X-ray diffraction (XRD) analyses were performed on samples of paint (380-2,920 mg Pb kg{sup -1}) and dust (200-1,000 mg Pb kg{sup -1}) collected prior to renovation. All dust samples exhibited a Pb XANES signature similar to that of Pb found in paint. Bulk XANES and micro-XRD identified Pb species commonly found as white paint pigments (Pb oxide, Pb sulfate, and Pb carbonate) as well as rutile, a titanium-based pigment, in the <150 {micro}m house dust samples. In the dust fraction <36 {micro}m, half of the Pb was associated with the Fe-oxyhydroxides, suggesting additional contribution of outdoor sources to Pb in the finer dust. These results confirm that old paints still contribute to Pb in the settled dust for this 65-year-old home. The Pb speciation also provided a clearer understanding of the Pb bioaccessibility: Pb carbonate > Pb oxide > Pb sulfate. This study underscores the importance of taking precautions to minimize exposures to Pb in house dust, especially in homes where old paint is exposed due to renovations or deterioration of painted surfaces.

X-ray absorption near-edge structure (XANES) and micro-X-ray diffraction (XRD) analyses were performed on samples of paint (380-2,920 mg Pb kg{sup -1}) and dust (200-1,000 mg Pb kg{sup -1}) collected prior to renovation. All dust samples exhibited a Pb XANES signature similar to that of Pb found in paint. Bulk XANES and micro-XRD identified Pb species commonly found as white paint pigments (Pb oxide, Pb sulfate, and Pb carbonate) as well as rutile, a titanium-based pigment, in the <150 m house dust samples. In the dust fraction <36 {mu}m, half of the Pb was associated with the Fe-oxyhydroxides, suggesting additional contribution of outdoor sources to Pb in the finer dust. These results confirm that old paints still contribute to Pb in the settled dust for this 65-year-old home. The Pb speciation also provided a clearer understanding of the Pb bioaccessibility: Pb carbonate > Pb oxide > Pb sulfate. This study underscores the importance of taking precautions to minimize exposures to Pb in house dust, especially in homes where old paint is exposed due to renovations or deterioration of painted surfaces.

    分析某装置反应器循环泵机械密封频繁泄漏量及端面温度高的原因.指出介质端密封载荷系数选择不当,导致密封端面比压偏小,是介质侧密封失效的主要原因;泵送环输送能力低,循环隔离液不能有效将密封摩擦热传递出去是导致大气侧端面温度高过高的主要原因.通过调整载荷系数和提高机械密封泵送能力,密封改造后使用寿命大幅提高,解决了循环泵机械密封频繁泄漏的问题.%The reason for the frequent leak on the mechanical seal of the circulating pump outside the reactor and for the high temperature on the seal end face was analyzed. Inappropriate load factor of the medium side seal leading to the low pressure on the seal end face was the main reason for the leakage of the seal. High temperature on atmospheric side was mainly caused by the low delivery capacity of pump ring and failure friction heat transfer of cycle fluid. By adjusting the load factor and improving the delivery capacity of the mechanical seal, the life of the mechanical seal is increased greatly after the renovation and the problem of frequently leak on mechanical seal of the circulating pump is solved.

  12. Lead toxicity: Current concerns

    Energy Technology Data Exchange (ETDEWEB)

    Goyer, R.A. (Univ. of Western Ontario, London (Canada))

    1993-04-01

    Over the 20-year period since the first issue of Environmental Health Perspectives was published, there has been considerable progress in the understanding of the potential toxicity of exposure to lead. Many of these advances have been reviewed in published symposia, conferences, and review papers in EHP. This brief review identifies major advances as well as a number of current concerns that present opportunities for prevention and intervention strategies. The major scientific advance has been the demonstration that blood lead (PbB) levels of 10-15 micrograms/dL in newborn and very young infants result in cognitive and behavioral deficits. Further support for this observation is being obtained by prospective or longitudinal studies presently in progress. The mechanism(s) for the central nervous system effects of lead is unclear but involve lead interactions within calcium-mediated intracellular messenger systems and neurotransmission. Effects of low-level lead exposure on blood pressure, particularly in adult men, may be related to the effect of lead on calcium-mediated control of vascular smooth muscle contraction and on the renin-angiotensin system. Reproductive effects of lead have long been suspected, but low-level effects have not been well studied. Whether lead is a carcinogen or its association with renal adenocarcinoma is a consequence of cystic nephropathy is uncertain. Major risk factors for lead toxicity in children in the United States include nutrition, particularly deficiencies of essential metals, calcium, iron, and zinc, and housing and socioeconomic status. A goal for the year 2000 is to reduce prevalence of blood lead levels exceeding 15 micrograms/dL. 97 refs.

    Nearly all scrap dealers, smelters and other recyclers routinely monitor for radioactivity in shipments entering their facility. These sensitive radiation gate monitors easily detect radium-226 and most other radioactive nuclides. However, the type of detector normally used, sodium iodide scintillation crystals, will not detect the low energy gamma radiation emitted by lead-210 and its progeny. Since lead-210 is a common radioactive contaminant in certain industries, contaminated scrap metal from these industries may avoid detection at the recycler. Lead-210 is a decay product of radon-222 which is produced in small concentrations with natural gas. As the natural gas liquids, particularly ethane and propane, are separated from the natural gas, the radon concentrates in the ethane/propane fraction. The natural gas industry, particularly gas processing facilities and industries using ethane and propane as feed stocks can be significantly contaminated with the radon decay products, especially lead-210, bismuth-210 and polonium-210. Unless the scrap metal is decontaminated before sending to the recycler, the lead-210 contaminated scrap may be processed, resulting in some degree of radioactive contamination of the recycling facilities. Methods of detecting the low energy gamma radiation associated with lead-210 include the pancake G-M detector and the thin crystal-thin window scintillation detector.

  4. Magnesium Diboride Current Leads

    2010-01-01

    A recently discovered superconductor, magnesium diboride (MgB2), can be used to fabricate conducting leads used in cryogenic applications. Dis covered to be superconducting in 2001, MgB2 has the advantage of remaining superconducting at higher temperatures than the previously used material, NbTi. The purpose of these leads is to provide 2 A of electricity to motors located in a 1.3 K environment. The providing environment is a relatively warm 17 K. Requirements for these leads are to survive temperature fluctuations in the 5 K and 11 K heat sinks, and not conduct excessive heat into the 1.3 K environment. Test data showed that each lead in the assembly could conduct 5 A at 4 K, which, when scaled to 17 K, still provided more than the required 2 A. The lead assembly consists of 12 steelclad MgB2 wires, a tensioned Kevlar support, a thermal heat sink interface at 4 K, and base plates. The wires are soldered to heavy copper leads at the 17 K end, and to thin copper-clad NbTi leads at the 1.3 K end. The leads were designed, fabricated, and tested at the Forschungszentrum Karlsruhe - Institut foer Technische Physik before inclusion in Goddard's XRS (X-Ray Spectrometer) instrument onboard the Astro-E2 spacecraft. A key factor is that MgB2 remains superconducting up to 30 K, which means that it does not introduce joule heating as a resistive wire would. Because the required temperature ranges are 1.3-17 K, this provides a large margin of safety. Previous designs lost superconductivity at around 8 K. The disadvantage to MgB2 is that it is a brittle ceramic, and making thin wires from it is challenging. The solution was to encase the leads in thin steel tubes for strength. Previous designs were so brittle as to risk instrument survival. MgB2 leads can be used in any cryogenic application where small currents need to be conducted at below 30 K. Because previous designs would superconduct only at up to 8 K, this new design would be ideal for the 8-30 K range.

    Full Text Available O acúmulo de resíduos poliméricos tem crescido nos últimos anos e os subsolos dos lixões já estão saturados com resíduos plásticos. Isso possivelmente se deve à elevada produção de resíduos sólidos de plásticos (cerca de 25 mil t/dia em 2008, segundo a Lei de Resíduos. Em vista disso, este trabalho apresenta uma análise comparativa do estudo do potencial de (biodegradação de compostos de PVC utilizando um plastificante de origem vegetal renovável (PFR com estrutura de éster de milho com massa molar 296,5 g.mol- 1 e dois plastificantes sintéticos, ftalato de dioctila (DOP e adipato de dioctila (DOA, buscando inovar na obtenção de um composto de PVC com um plastificante de fonte renovável. Os resultados de FTIR evidenciaram maior interação do PFR com a resina de PVC para o teor de 30 phr, e para o teor de 40 phr observou-se que os plastificantes DOP e PFR apresentaram os mesmos valores de variação da banda atática. Já os ensaios mecânicos reforçaram os resultados de FTIR com maior compatibilidade para as composições contendo PFR. Uma maior estabilidade térmica no composto de PVC foi observada por TGA para a amostra contendo 40 phr de DOA, o que foi confirmado por RMN, e para a amostra com PFR nos teores de 30 e 40 phr. Por fim, uma perda significativa de massa foi observada nos ensaios de resistência à extração por solvente para os compostos contendo DOA, sendo que a amostra com 30 phr mostrou menor valor de extração. A biodegradação em solo simulado mostrou maior perda de massa para as amostras plastificadas com DOA (40phr e PFR (40phr. Isso indica que é viável usar plastificante de fonte renovável nos compostos de PVC, devido à compatibilidade deste com esta resina.

    1976-03-01

    Twenty-seven dogs with lead poisoning were admitted to the University of Pennsylvania Veterinary Hospital from July, 1963, to April, 1975. The major source of the lead was paint. A common history was ingestion of plaster or paint scrapings during room renovation. Most of the dogs were less than 1 year old and had clinical signs referable to the gastrointestinal or the nervous system, or both. The gastrointestinal signs, in order of frequency, were vomiting, anorexia, tender abdomen, diarrhea, and constipation. The neurologic signs, in order of frequency, were hysteria, convulsions, ataxia, blindness, and mydriasis. The finding of many nucleated erythrocytes without severe anemia was nearly pathognomonic for lead poisoning. Of 14 affected dogs subjected to abdominal radiography, 9 had evidence of ingested radiopaque material. A mean blood lead concentration of 18.8 ..mu..g/100 ml, with a range of 0 to 50 ..mu..g/100 ml, was found for 26 dogs that were hospitalized for problems unrelated to lead poisoning. Of the 27 dogs with lead poisoning, 22 had their blood analyzed for lead. This group had blood lead values ranging from 40 to 530 ..mu..g/100 ml. Seven of the affected dogs were monitored throughout their period of treatment with calcium ethylene-diaminetetraacetate. The concentration of lead in the blood decreased quickly after the initiation and treatment but leveled off after 2 or 3 days. The initial rapid phase probably corresponded to the removal of weakly bound or extracellular lead, whereas the slow phase probably corresponded to strongly bound or intracellular lead. 22 references.

    Healthcare institutions and providers are in complexity. Networks of interconnections from relationships and technology create conditions in which interdependencies and non-linear dynamics lead to surprising, unpredictable outcomes. Previous effective approaches to leadership, focusing on top-down bureaucratic methods, are no longer effective. Leading in complexity requires leaders to accept the complexity, create an adaptive space in which innovation and creativity can flourish and then integrate the successful practices that emerge into the formal organizational structure. Several methods for doing adaptive space work will be discussed. Readers will be able to contrast traditional leadership approaches with leading in complexity. They will learn new behaviours that are required of complexity leaders, along with challenges they will face, often from other leaders within the organization.

    Ten years ago, Sarah Stevens-Rayburn and Ellen Bouton presented a paper entitled "If it's not on the Web, it doesn't exist at all: Electronic Information Resources — Myth and Reality." How much has changed since this paper was presented? The STScI Library is in a unique position to explore this question. In 2008, we underwent a massive renovation during which time our print collection was sequestered in a storage area for nine months. Our newly refurbished library had 30% less shelf space than the original. This prompted us to ask the questions "How much of it is online?" "Do we need to keep the print?" "How can we tie our print collection to online research tools?" and "How do different parts of our collection behave?"

    As a ecological treating techniques, the land treatment systemsare of good developing prospects because of its advantages, such as simple of facilities, economization of investment, convenience of operation, lower cost of energy and better effect of purgation. This paper summarizes the research status of wastewater land treatment system home and abroad. From the characteristics of municipal water supplying, draining and application in China at present, this paper also presents three aspects of carrying out wastewater renovation on using the techniques of land treatment in municipal water circulation as follows:renovation of domestic wastewater produced by inhabitants in cities or towns, renovation of wastewater of cities by land treatment techniques and light polluted original water pretreatment for supplement. Among them, sand filter system and wetland system used for renovation of domestic wastewater have problems of lower hydraulic loading and disposal capability. How to solve the problems is a meaningful study. The techniques used for disposing of city wastewater have been mature,but the problem is that the covered land is too large. Therefore, adjusting measures to local conditions depending on the local circumstance is a good way. Application of land treatment techniques to pretreatment of lighter polluted water for drinking water supply is a new study direction. The application offers some possibilities for solving the problem of positivity of Ames test and others, which could not be solved by biological pretreatment techniques, and it is also a cheap and effective method too%土地处理作为一种生态处理技术以其设备简单、投资少、操作管理方便、能耗低,以及净化效果良好而具有广阔的发展前景。文中系统总结了污水土地处理系统国内外研究现状,结合当前中国城市供、排水以及用水的特点,提出了在城市水循环中应用土地处理技术,实现污水资源化的三个方向

All of these observations except that of Daunt were made by the direct measurement of electrical resistance. Daunt`s method involved the shielding effect of persistent currents in a hollow cylinder. In the authors work on columbium to be described in a forthcoming paper an a.c. induction method was used for the measurement of superconducting transitions. The superconductor was mounted as a cylindrical core of a coil which functioned as the secondary of a mutual inductance. The primary coil was actuated by an oscillator which provided a maximum a.c. field within the secondary of 1.5 oersteds at a frequency of 1000 cycles per second. The secondary e.m.f. which was dependent for its magnitude on the permeability of the core was amplified, rectifie, and observed on a recording potentiometer. During the application of this method to the study of columbium it appeared that a further check on the zero-field transition temperature of lead would be worth while especially if agreement between results for very pure samples could be obtained using this method. Such result would help in establishing the lead transition temperature as a reasonably reproducible reference point in the region between 4 deg and 10 deg K.

  14. lead glass brick

    CERN Multimedia

    When you look through the glass at a picture behind, the picture appears raised up because light is slowed down in the dense glass. It is this density (4.06 gcm-3) that makes lead glass attractive to physicists. The refractive index of the glass is 1.708 at 400nm (violet light), meaning that light travels in the glass at about 58% its normal speed. At CERN, the OPAL detector uses some 12000 blocks of glass like this to measure particle energies.

    For years the field of entrepreneurship has been blinded by the alchemical promise of turning lead into gold, of finding the ones most likely to become the next Branson, Zuckerberg or Gates. The promise has been created in the midst of political and scientific agendas where certain individuals...... is not to accumulate state or market wealth, but for entrepreneurial skills to become tools towards the liberation of the individual from oppressive systems of control – essentially to add public value rather than economic value. In this presentation I will sketch an anarchist perspective on entrepreneurship, looking...

The land base of rural residential areas is experiencing a reverse development trend of "population decrease but land increase". The main reason is that the rural residential areas have been in a disordered development state with a chaotic layout for a long time. Under the platform of the new round of land renovation planning, rural settlement remediation is being launched all over the country. Estimation of land-renovation potential and determination of the mode of rural residential areas is an important constituent part of land renovation planning. The study area belongs to the "5.12" earthquake disaster area, an earthquake that caused great damage to residents’ production and life. According to

    2005-01-01

    Cofilin has emerged as a key regulator of actin dynamics at the leading edge of motile cells. Through its actin-severing activity, it creates new actin barbed ends for polymerization and also depolymerizes old actin filaments. Its function is tightly regulated in the cell. Spatially, its activity is restricted by other actin-binding proteins, such as tropomyosin, which compete for accessibility of actin filament populations in different regions of the cell. At the molecular level, it is regulated by phosphorylation, pH and phosphatidylinositol (4,5)-bisphosphate binding downstream of signaling cascades. In addition, it also appears to be regulated by interactions with 14-3-3zeta and cyclase-associated protein. In vivo, cofilin acts synergistically with the Arp2/3 complex to amplify local actin polymerization responses upon cell stimulation, which gives it a central role in setting the direction of motility in crawling cells.

  3. Lead telluride alloy thermoelectrics

    2011-11-01

    Full Text Available The opportunity to use solid-state thermoelectrics for waste heat recovery has reinvigorated the field of thermoelectrics in tackling the challenges of energy sustainability. While thermoelectric generators have decades of proven reliability in space, from the 1960s to the present, terrestrial uses have so far been limited to niche applications on Earth because of a relatively low material efficiency. Lead telluride alloys were some of the first materials investigated and commercialized for generators but their full potential for thermoelectrics has only recently been revealed to be far greater than commonly believed. By reviewing some of the past and present successes of PbTe as a thermoelectric material we identify the issues for achieving maximum performance and successful band structure engineering strategies for further improvements that can be applied to other thermoelectric materials systems.

    many environmental obstacles exist. Bolivia, Ecuador and Peru are the South American countries that still have the greatest availability of economically viable water resources to be exploited, since those countries do not even use 7% of the available potential. Venezuela and Paraguay stand out in South America as using more than 50% of the economically available potential for hydroelectric generation in the region. Geothermal energy is an important resource in Mexico and Central America, with an installed capacity of 965 MW and 502 MW in 2008, respectively. In those two cases, this is the primary source of power generation. Argentina's high-enthalpy fields are sufficient for geothermal use to generate energy, but there is no estimate of the generation potential. Chile is another country that tries to develop its geothermal potential. In 2009, the government of Chile requested bids for 20 contracts for geothermal energy exploitation. During the geothermal bidding process, 59 offers from exploitation projects were received and 9 companies were granted licenses for the 20 areas solicited. Biomass is an especially important energy resource in Brazil, where it has already surpassed CHP. It is also relevant in Argentina and Colombia, where it is associated with the alcohol-sugar industry and a growing interest in cogeneration systems.

  7. Leading from the boardroom.

    2008-04-01

    These days, boards are working overtime to comply with Sarbanes-Oxley and other governance requirements meant to protect shareholders from executive wrongdoing. But as directors have become more hands-on with compliance, they've become more hands-off with long-range planning. That exposes corporations and their shareholders to another--perhaps even greater--risk, say professors Lorsch, of Harvard Business School, and Clark, of Harvard Law School. Boards are giving the long term short shrift for a number of reasons. Despite much heavier workloads, directors haven't rethought their patterns of operating - their meetings, committees, and other interactions. Compliance has changed their relationship with executives, however, turning directors into micromanagers who closely probe executives' actions instead of providing high-level guidance. Meanwhile, the pressure to meet quarterly expectations intensifies. Directors need to do a better job of balancing compliance with forward thinking. Boardroom effectiveness hinges most on the quality of directors and their interactions, the authors' research shows. Directors must apply their wisdom broadly, handling compliance work more efficiently and staying out of the weeds on strategic issues. Using their power with management to evangelize for long-term planning, they must take the lead on discussions about financial infrastructure, talent development, and strategy. Reserving sacrosanct time for such discussions, as Philips Electronics' board does at annual retreats, is an effective practice: After one recent retreat, Philips decided to exit the semiconductor business, where it was losing ground. Individual directors also must not shy away from asking tough questions and acting as catalysts on critical issues, such as grooming a successor to the CEO. In short, directors must learn to lead from the boardroom.

  11. Drowning: a leading killer!

    Directory of Open Access Journals (Sweden)

    Nuno Domingos Garrido

    2016-10-01

    Full Text Available Drowning kills at least 372,000 people worldwide every year and is the 3rd leading cause of unintentional death, accounting for 7% of all deaths stemming from accidents (WHO, 2014. Conceptually, “drowning” is a complex and multi-faceted phenomenon, characterized as a chain of events (Bierens, 2006. Drowning is defined as the process of experiencing respiratory impairment from immersion or submersion in liquid. Research on drowning as a phenomenon presents several difficulties - most of all, that global data concerning the number of occurrences are not accurate. Nevertheless, detailed analysis of the registered incidents allows the identification of risk factors of drowning. An in-depth analysis of the risk factors is the basis for the creation of targeted and effective strategies to prevent drowning. Due to variability of situations which could lead to a drowning episode, experts suggest the adoption of a multi-layer prevention model, rather than opting for isolated measures, since no single measure can prevent all deaths and injuries caused by submersion. Among the preventive measures we would like to emphasize instruction in swimming and water safety. So, what does "knowing how to swim" really mean? Some authors define mastery of this competence as swimming a given distance, while others put the emphasis on how this/any given distance is swum (Stallman, Junge, & Blixt, 2008. It has long been realized that there is no contradiction between learning those competencies which make a person less susceptible to drowning and those competencies which prepare the path towards higher levels of performance and competition. Aquatic movement researchers and practitioners and drowning prevention researchers and practitioners, share in the responsibility for drowning prevention though they are often unaware of it. The question “What should be taught to children?” is too infrequently asked. There remains great variation in what is taught and programs

  12. Leading Your Leaders

    Science.gov (United States)

    Hale, Wayne N.

    2008-01-01

    life is good. More often when an unbelievably difficult test fails, we are left with a very long discussion of why and what was wrong in the design or execution of the test. Make sure that the test is well defined. Even then, it is important to explain to your leaders what inherent accuracy (or error) the test conditions or equipment have and what the assumptions or initial conditions were for the test. Test results without a good understanding of the test's accuracy or the pedigree of the test assumptions are worth very little. Finally, there is flight test data. Always limited, never at the edge of the envelope, it still shows how the real hardware works in a combined environment. Flight experience is dangerous because it typically doesn't show how close to the edge of the cliff the equipment is operating, but it does demonstrate how the hardware really works. A flight test is the ultimate test, again taken with the knowledge that it is probably not the extreme but something more like the middle of the environmental and systems performance. Good understanding of a problem and its solution always relies on a combination of all these methods. Be sure to lead your leaders by using all the tools you have at your disposal. At the end of the day, decisions in space flight always come down to a risk trade. Our business is not remotely safe, not in the sense that the public, the media, or our legislators use the term. Everything we do has a risk, cost, schedule, or performance trade-off. For your leaders to make an appropriate decision, you need to educate them, lead them, talk with them, and engage them in the discussion until full understanding takes place. It's your job. *

    2012-01-01

    运用西方政治经济学公共选择理论的“经济人理性-利益最大化-公共选择”的理论框架,分析广州市“三旧”改造实践,验证了“公共选择”理论的适用性,即“经济人”作出的政治决策和经济决策同样追求自身利益的最大化.并以完成改造的若干旧村为实例,深入解析了旧城改造过程中市(区)政府、开发商、村集体、村民之间的公共选择行为动机和结果.肯定了“三旧”改造对于提高土地集约利用效率和提升城市品质方面的积极意义,同时反思了政府强力推进旧城改造的“公平与效率”问题.%Based on the analysis framework of "rational economic man-benefit maximization-public choice" which comes from the western political and economic public choice theory, this paper analyzes the practice of Guangzhou old city renovation and proves the applicability of that theory: the "economic man" pursues his maximum interests both in political decision-making and economic decision-making. Furthermore, through some examples of finished old village renovation projects, this paper analyzes the motives and results of the public choice behaviors of the municipal government, developers, village collective, and villagers during the old city renovation process. The paper affirms the positive effects of old city renovation on improving land-use efficiency and promoting city quality, and also rethinks the problem of "justice and efficiency" in the renovation.

    Tsing Hua University was recently granted by National Science Council a five-year project to renovate its Open-Pool reactor (THOR) for boron neutron capture therapy. With this support, the whole graphite blocks in the original thermal column region can be removed for redesigning and constructing a better epithermal neutron beam. THOR is a 1 MW research reactor. The cross section area of the core facing the thermal column is 60 cm x 50 cm. By using 60 cm FLUENTAL plus 10 cm Pb, with cross section area of 70 cm x 60 cm and surrounded by 6 cm thick PbF{sub 2} reflector, the epithermal neutron flux at the filter/moderator exit can reach {approx}8.5 x 10{sup 9} n/cm{sup 2}/s. When the collimator is added, the epithermal neutron beam intensity at the beam exit is reduced to 3 x 10{sup 9} n/cm{sup 2}/sec, but is still six times higher than the previous beam. Facing the clinical trials scheduled 3 and half years from now, a preliminary version of treatment planning system is developed. It includes a pre-processor to read CT scan and post-processors to display dose distributions. (author)
