    Costs for disposal of sludges from a municipal wastewater treatment plant normally represents greater than or equal to 25% of the total plant operating cost. The following 5 sludge handling options are considered: chemical conditioning followed by vacuum filtration, and incineration; high-pressure wet-air oxidation and vacuum filtration or filter press prior to incineration; thermal conditioning, vacuum filtraton, and incineration; high-pressure wet-air oxidation and vacuum filtration, with ash to landfill; aerobic or anaerobic digestion, followed by chemical conditioning, vacuum filtration, and disposal on land; and chemical conditioning, followed by a filter press, flash dryer, and sale as fertilizer. The 1st 2 options result in the ultimate disposal of small amounts of ash in a landfill; the digestion options require a significant landfill; the fertilizer option requires a successful marketing and sales effort. To compare the economies of scale for the options, analyses were performed for 3 plant capacities - 10, 100, and 500 mgd; as plant size increases, the economies of scale for incineration system are quite favorable. The anaerobic digestion system has a poorer capital cost-scaling factor. The incinerator options which start with chemical conditioning consume much less electrical power at all treatment plant sizes; incinerator after thermal conditioning uses more electricity but less fuel. Digestion requires no direct external fossil fuel input. The relative use of fuel is constant at all plant sizes for other options. The incinerator options can produce a significant amount of steam which may be used. The anaerobic digestion process can be a significant net producer of fuel gas.

    It has traditionally been argued that recycling municipal solid waste (MSW) is usually not economically viable and that only when externalities, long-term dynamic considerations, and/or the entire product life cycle are taken into account, recycling becomes worthwhile from a social point of view. This article explores the results of a wide study conducted in Israel in the years 2000 2004. Our results reveal that recycling is optimal more often than usually claimed, even when externality considerations are ignored. The study is unique in the tools it uses to explore the efficiency of recycling: a computer-based simulation applied to an extensive database. We developed a simulation for assessing the costs of handling and treating MSW under different waste-management systems and used this simulation to explore possible cost reductions obtained by designating some of the waste (otherwise sent to landfill) to recycling. We ran the simulation on data from 79 municipalities in Israel that produce over 60% of MSW in Israel. For each municipality, we were able to arrive at an optimal method of waste management and compare the costs associated with 100% landfilling to the costs born by the municipality when some of the waste is recycled. Our results indicate that for 51% of the municipalities, it would be efficient to adopt recycling, even without accounting for externality costs. We found that by adopting recycling, municipalities would be able to reduce direct costs by an average of 11%. Through interviews conducted with representatives of municipalities, we were also able to identify obstacles to the utilization of recycling, answering in part the question of why actual recycling levels in Israel are lower than our model predicts they should be.

    This paper reports that it has been estimated that the burning of fossil fuels and the clearing of forests account for 6-7 billion tons of carbon emissions each year. Combustion also results in significant emissions of sulfur oxides and nitrogen oxides. While the growth in the use of fuels has slowed considerably in the developed regions of North America, western Europe, and Japan over the past decade, pressure for increased energy use and the clearing of forests can be expected with even moderate economic and population growth in the developing regions of Asia, Africa, and Latin America. Researchers at the Institute for Economic Analysis have begun the formulation and analysis of alternative scenarios describing environmentally sound economic development over the next 50 years. These scenarios include activities aimed at improving the standards of living in developing countries while reducing emissions of the aforementioned gases or removing carbon from the atmosphere. Specific alternatives include tropical forestation; the adoption of relatively clean and efficient boilers, especially for the production of electricity in developing countries, as well as greater use of cogeneration systems and hydroelectricity; alternative transportation strategies; and conservation of energy in households of rich and middle-income countries (e.g., efficient lighting fixtures, appliances, and cooling equipment)

    Full Text Available The article focuses on the need of integration of municipal government into a unified hierarchy of strategic planning in the country. The basic positions of the acting version of the Federal law no.131 “On general principles of organization of local self-government” and the Federal law no. 172 “On strategic planning” don’t provide clear legal framework for the solution of this problem. Besides, the practical integration of municipal management into a unified hierarchy of strategic planning meets serious economic obstacles, the main of which consist in the negative situation within the system of local finance, characterized by trends of deficiency, high dependence on subsidies and, as a consequence, volatility and lack of predictability in relation to any plans and programs of long-term nature. The main idea of the article is to prove the need for a systemic approach to solving tasks, related to the integration of municipal management in a unified vertical of strategic planning in the country. The essence of this approach is the combination of a number of legal innovations in the legislation on strategic planning and local government with a set of measures, aimed to strengthen the fiscal basis of Russian local self-government together with institutional ensuring of municipal planning and its interaction with the practice of strategic planning at the level of subjects of the Russian Federation.

    The universalization of basic care and commitment budget of the Ministry of Health with the Family Health Strategy (ESF) through new systematic financing incentives have been highlighted in the Brazilian health policy scenario. One of the great problems observed is the expansion of the strategy for large urban centres. This paper studies the economic-financial sustainability of ESF in Brazilian municipalities of more than 100 thousand inhabitants according to some selected indicators, considering the geographical region to which they belong, their population size and participation in Project for the Expansion and Consolidation Family Health (Proesf). Municipalities belonging to the Southeast region, more developed of the country, have on average better economic-financial performance, but lower average values of coverage of ESF. Municipalities from the North and Northeast, with the lowest average for economic-financial sustainability indicators, were the ones that made more effort to developments in the period. Thus, we observed the dynamics between bigger fiscal capacity and budgetary commitment with the Health Sector for biggest municipalities and in more economically developed regions, and greater vulnerability and dependence of federative transferences for municipalities with less people, in less developed areas.

    This paper points out the advantages and disadvantages of municipal solid waste processing methods incorporating different energy and/or materials recovery techniques, i.e., those involving composting or incineration and those with a mix of composting and incineration. The various technologies employed are compared especially with regard to process reliability, flexibility, modularity, pollution control efficiency and cost effectiveness. For that which regards composting, biodigestors are examined, while for incineration, the paper analyzes systems using combustion with complete recovery of vapour, combustion with total recovery of available electric energy, and combustion with cogeneration. Each of the processing methods examined includes an iron recovery cycle

  16. The cost of LLW disposal - Is it sound economics?

    1992-01-01

    Low-level radioactive waste (LLW) management is a growth industry. Since 1980, when the LLW Policy Act was passed, regional and state LLW bureaucracies have grown, and LLW services and consulting businesses have prospered. Most states and federal agencies have LLW programs with increased regulation of LLW management. Costs of all these programs have soared as facilities for LLW disposal are proposed in sixteen, or more, locations in the country. LLW management costs have also increased as licensees implement comprehensive programs for volume reduction and waste form stabilization. Yet, the total cost of LLW management service is borne by nearly the same universe of payers as in 1980: taxpayers and radioactive materials licensees. Those costs are, in turn, passed on through taxes and consumer costs. Ultimately, everybody pays. Despite this investment, the LLW situation is adrift. New facilities have not been built, and existing facilities are closing or limiting access. LLW management has not advanced to a respected field of engineering and science. Nor does it include exceptional benefit and opportunity to host communities. A new focus is needed to allow an economically sound solution to emerge, one where the supply of LLW management and disposal fits the demand for service. (author)

    Full Text Available This paper evaluates the importance of infrastructure on economic growth for the Mexican northern border municipalities. From the growth literature, we know that infrastructure, besides other factors, has been pointed out as a key factor in the long run perspectives of regional growth. Nevertheless, and within this thematic context, works that use a disaggregated analysis down to the level of the municipality are still scarce, which in the case of the northern border constitutes a scenario of much relevance given the development model adopted by the Mexican economy in recent decades. Empirical models results indicate that the municipalities of Piedras Negras, Nogales and Torreon maintain a positive relationship between physical infrastructure and growth. In the case of other municipalities like Tijuana, its elevated population growth inhibits a proper infrastructure allocation, although the positive effect induced by infrastructure on growth remains.

    The application of Directive 2008/98/CE on Municipal Solid Waste (MSW) implies the need to introduce technologies to generate energy from waste. Incineration, the most widely used method, is difficult to implement in low populated areas because it requires a large amount of waste to be viable (100,000 tons per year). This paper analyses the economic and environmental costs of different MSW-to-Energy technologies (WtE) in an area comprising of 13 municipalities in southern Spain. We analyse anaerobic digestion (Biomethanization), the production of solid recovered fuel (SRF) and gasification, and compare these approaches to the present Biological Mechanical Treatment (BMT) with elimination of the reject in landfill, and incineration with energy recovery. From an economic standpoint the implementation of WtE systems reduces the cost of running present BMT systems and incineration; gasification presents the lowest value. From the environmental standpoint, Life Cycle Assessment shows that any WtE alternatives, including incineration, present important advantages for the environment when compared to BMT. Finally, in order to select the best alternative, a multi-criteria method is applied, showing that anaerobic digestion is the optimal solution for the area studied. Copyright © 2017 Elsevier Ltd.

    2015-09-08

    While previous research already exists on the impact of the current economic crisis and whether it leads to an increase in mortality by suicide, our objective in this paper is to determine if the increase in the suicide rate in Catalonia, Spain from 2010 onwards has been statistically significant and whether it is associated with rising unemployment. We used hierarchical mixed models, separately considering the crude death rate of suicides for municipalities with more than and less than 10,000 inhabitants as dependent variables both unstratified and stratified according to gender and/or age group. In municipalities with 10,000 or more inhabitants there was an increase in the relative risk of suicide from 2009 onwards. This increase was only statistically significant for working-aged women (16-64 years). In municipalities with less than 10,000 inhabitants the relative risk showed a decreasing trend even after 2009. In no case did we find the unemployment rate to be associated (statistically significant) with the suicide rate. The increase in the suicide rate from 2010 in Catalonia was not statistically significant as a whole, with the exception of working-aged women (16-64 years) living in municipalities with 10,000 or more inhabitants. We have not found this increase to be associated with rising unemployment in any of the cases. Future research into the effects of economic recessions on suicide mortality should take into account inequalities by age, sex and size of municipalities.

    Khe Sun, Pak; Vorona-Slivinskaya, Lubov; Voskresenskay, Elena

    2017-10-01

    The article highlights the necessity of a complex approach to assess economic security of municipalities, which would consider municipal management specifics. The approach allows comparing the economic security level of municipalities, but it does not describe parameter differences between compared municipalities. Therefore, there is a second method suggested: parameter rank order method. Applying these methods allowed to figure out the leaders and outsiders of the economic security among municipalities and rank all economic security parameters according to the significance level. Complex assessment of the economic security of municipalities, based on the combination of the two approaches, allowed to assess the security level more accurate. In order to assure economic security and equalize its threshold values, one should pay special attention to transportation system development in municipalities. Strategic aims of projects in the area of transportation infrastructure development in municipalities include the following issues: contribution into creating and elaborating transportation logistics and manufacture transport complexes, development of transportation infrastructure with account of internal and external functions of the region, public transport development, improvement of transport security and reducing its negative influence on the environment.

  7. The spatial distribution of gambling and its economic benefits to municipalities in the Czech Republic

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available Gambling is a specific type of economic activity that significantly affects many aspects of society. It is associated mainly with negative impacts on the lives of individuals and their families, but it also has a positive economic impact on the public budgets of states, regions and municipalities. In this article, we focus on a geographic assessment of the development of gambling in the Czech Republic, which is based on a spatial analysis of data on licensed games and data on the revenues of municipalities arising from gambling. It turns out that the occurrence of gambling is strongly influenced by binary centre/periphery dichotomy, with the exception of the Czech-Austrian and Czech-German border areas which are characterised by a high concentration of casinos resulting from more rigid regulation of gambling on the other side of the border. In this research, the authors develop an innovative scientific discipline within Czech human geography: The geography of gambling.

    2014-01-01

    Commuting is one of the main contributors to the high energy consumption patterns in modern economies. The need to reduce the energy spent in commuting has attracted the attention of academics and policy makers. The main goal of this research is to improve knowledge of the economic, social, energy and environmental opportunity costs of inter-municipality commuting and to support policy-oriented strategies that explicitly take them into account. For this, we use hypothetical assumptions based on the baseline scenario that Portuguese households do not travel between municipalities for commuting purposes coupled with the expected changes in private final consumption. Accordingly, the direct, indirect and induced opportunity costs of inter-municipality commuting are assessed using an input–output model. The significance of the estimated virtual net benefits of commuting is analyzed according to their macroeconomic (GVA, taxes, international imports and employment), energy (primary energy consumption) and environmental (CO 2 emissions) dimensions. The results obtained empirically indicate that inter-municipality commuting has significant opportunity costs in the GVA and GDP as well as in primary energy consumption and CO 2 emissions. The results also indicate that commuters in metropolitan regions and long-distance commuters are responsible for a major share of these opportunity costs. - Highlights: • This paper provides an insight into the magnitude of opportunity costs of commuting. • Input–output modeling is valuable to assess changes in final consumption patterns. • About 25% of household's fuel consumption is due to inter-municipality commuting. • Inter-municipality commuting has net negative effects on GDP, GVA and employment. • The main opportunity costs come from metropolitan and long distance commuting

    Muddled about what makes music? Stuck on the study of harmonics? Dumbfounded by how sound gets around? Now you no longer have to struggle to teach concepts you really don t grasp yourself. Sound takes an intentionally light touch to help out all those adults science teachers, parents wanting to help with homework, home-schoolers seeking necessary scientific background to teach middle school physics with confidence. The book introduces sound waves and uses that model to explain sound-related occurrences. Starting with the basics of what causes sound and how it travels, you'll learn how musical instruments work, how sound waves add and subtract, how the human ear works, and even why you can sound like a Munchkin when you inhale helium. Sound is the fourth book in the award-winning Stop Faking It! Series, published by NSTA Press. Like the other popular volumes, it is written by irreverent educator Bill Robertson, who offers this Sound recommendation: One of the coolest activities is whacking a spinning metal rod...

  10. Municipal waste processing: Technical/economic comparison of composting and incineration options

    Bertanza, G.

    1993-01-01

    The first part of this paper which assessed the state-of-the-art of municipal waste composting and incineration technologies indicated that the advanced level of available technologies in this field now allows the realization of reliable and safe plants. This second part of the paper deals with the economics of the composting and incineration options. Cost benefit analyses using the discounted cash flow method are made for waste processing plants featuring composting alone, incineration only and mixed composting and incineration. The economic analyses show that plants employing conventional composting techniques work well for the case of exclusively organic waste materials. Incineration schemes are shown to be economically effective when they incorporate suitable energy recovery systems. The integrated composting-incineration waste processing plant appears to be the least attractive option in terms of economics. Current R ampersand D activities in this field are being directed towards the development of systems with lower environmental impacts and capital and operating costs

    2010-01-01

    Recycling of paper and glass from household waste is an integrated part of waste management in Denmark, however, increased recycling is a legislative target. The questions are: how much more can the recycling rate be increased through improvements of collection schemes when organisational and technical limitations are respected, and what will the environmental and economic consequences be? This was investigated in a case study of a municipal waste management system. Five scenarios with alternative collection systems for recyclables (paper, glass, metal and plastic packaging) were assessed by means of a life cycle assessment and an assessment of the municipality's costs. Kerbside collection would provide the highest recycling rate, 31% compared to 25% in the baseline scenario, but bring schemes with drop-off containers would also be a reasonable solution. Collection of recyclables at recycling centres was not recommendable because the recycling rate would decrease to 20%. In general, the results showed that enhancing recycling and avoiding incineration was recommendable because the environmental performance was improved in several impact categories. The municipal costs for collection and treatment of waste were reduced with increasing recycling, mainly because the high cost for incineration was avoided. However, solutions for mitigation of air pollution caused by increased collection and transport should be sought.

    This paper analyzes the implications of municipal budget revenue growth and the monetary policy's inflation rates goals in the availability of public health resources of municipalities. This is a descriptive, exploratory, quantitative, retrospective and longitudinal cross-sectional study covering the period 2002-2011. We analyzed health financing and expenditure variables in the municipalities of the state of Pernambuco, Brazil, describing the trend and the relationship between them. Data showed the growth of the variables and trend towards homogeneity. The exception was for the participation of Intergovernmental Transfers in the Total Health Expenditure of the Municipality. We found a significant correlation between Budget Revenue per capita and Health Expenditure per capita and a strong significant negative correlation between Inflation Rate, Budget Revenue per capita and Health Expenditure per capita. We concluded that increased health expenditure is due more to higher municipal tax revenue than to increased transfers that, in relative terms, did not increase. The strong inverse relationship between inflation rate and the Financing and Expenditure variables show that the monetary policy's inflation goals have restricted health financing to municipalities.

    The main aim of this study was to perform a Life cycle assessment study as well as an economic evaluation of the recovery of recyclable materials in a municipal solid waste management system. If citizens separate erroneously waste fractions, they produce both environmental and economic damages. The environmental and economic evaluation was performed for the case study of Nola (34.349 inhabitants) in Southern Italy, with a kerbside system that assured a source separation of 62% in 2014. The economic analysis provided a quantification of the economic benefits obtainable for the population in function of the achievable percentage of source separation. The comparison among the environmental performance of four considered scenarios showed that the higher the level of source separation was, the lower the overall impacts were. This occurred because, even if the impacts of the waste collection and transport increased, they were overcome by the avoided impacts of the recycling processes. Increasing the source separation by 1% could avoid the emission of 5 kg CO 2 eq. and 5 g PM10 for each single citizen. The economic and environmental indicators defined in this study provide simple and effective information useful for a wide-ranging audience in a behavioural change programme perspective.

    Sound therapy coupled with appropriate counseling has gained widespread acceptance in the audiological management of tinnitus. For many years, ear level sound generators (SGs) have been used to provide masking relief and to promote tinnitus habituation. More recently, an alternative treatment device was introduced, the Neuromonics Tinnitus Treatment (NTT), which employs spectrally-modified music in an acoustic desensitization approach in order to help patients overcome the disturbing consequences of tinnitus. It is unknown, however, if one treatment plan is more efficacious and cost-effective in comparison to the other. In today's economic climate, it has become critical that clinicians justify the value of tinnitus treatment devices in relation to observed benefit. To determine perceived benefit from, and economic value associated with, two forms of sound therapy, namely, SGs and NTT. Retrospective between-subject clinical study. A sample of convenience comprised of 56 patients drawn from the Tinnitus Management Clinic at the Cleveland Clinic participated. Twenty-three patients selected SGs, and 33 patients selected NTT as their preferred sound therapy treatment option. Sound therapy benefit was quantified using the Tinnitus Handicap Inventory (THI). The questionnaire was administered before and 6 mo after initiation of tinnitus treatment. Prior to device fitting, all patients participated in a 1.5 hr group education session about tinnitus and its management. Economic value comparisons between sound therapy options were made using a cost-effectiveness analysis (CEA) and cost-utility analysis (CUA). THI scores indicated a significant improvement (p 0.05) between the treatment alternatives at baseline or 6 mo postfitting. The magnitude of improvement for both SGs and NTT was dependent on initial perceived tinnitus handicap. Based on the CEA and CUA economic analyses alone, it appears that the SGs may be the more cost-effective alternative; however, the magnitude of

    Research highlights: → Legal and economic opinions of free interstate trade of MSW in the US are reviewed. → Economic theory of landfill space as the article of commerce can align opinions. → Waste management policies implied by this economic theory are compared/contrasted. - Abstract: Managing municipal solid waste (MSW) within and across regions is a complex public policy problem. One challenge regards conceptualizing precisely what commodity is to be managed across space and time. The US Supreme Court view is that waste disposal is the article of commerce per se. Some justices, however, have argued that while waste disposal is the article of commerce, its interstate flow could be impeded by states on the grounds that they have the authority to regulate natural resource quality within their boundaries. The argument in this paper is that adopting the economic theory view of the article of commerce as landfill space brings the majority and dissenting US Supreme Court views-and the resulting sides of the public policy dispute-into closer alignment. We discuss waste management policy tools that emerge from this closer alignment that are more likely to both withstand judicial scrutiny and achieve economic efficiency.

    Several celebrated scholars argue that diverse preferences and coordination failure due to ethnic and cultural diversity hamper the social cohesion necessary for good economic management, leading to development failure. Using several measures of diversity, we find that higher levels of ethno-linguistic and cultural fractionalization are conditioned positively on higher economic growth by an index of economic freedom, which is often heralded as a good measure of sound economic management. High diversity in turn is associated with higher levels of economic freedom. We do not find any evidence to suggest that high diversity hampers change towards greater economic freedom and institutions supporting liberal policies. The effect of diversity, moreover, is conditioned positively by higher democracy. Our results raise serious doubt about the centrality of social diversity for explaining economic failure, nor is there evidence to suggest that autocratic measures are required under conditions of social diversity to implement growth-promoting policies. This is good news because history and culture seem to matter less than rational agency for ensuring sound economic management. Copyright © 2016 Elsevier Inc. All rights reserved.

    The article presents the technical and economic analysis of the production of fuels from municipal sewage sludge. The analysis involved the production of two types of fuel compositions: sewage sludge with sawdust (PBT fuel) and sewage sludge with meat and bone meal (PBM fuel). The technology of the production line of these sewage fuels was proposed and analysed. The main objective of the study is to find the optimal production capacity. The optimisation analysis was performed for the adopted technical and economic parameters under Polish conditions. The objective function was set as a maximum of the net present value index and the optimisation procedure was carried out for the fuel production line input capacity from 0.5 to 3 t h(-1), using the search step 0.5 t h(-1). On the basis of technical and economic assumptions, economic efficiency indexes of the investment were determined for the case of optimal line productivity. The results of the optimisation analysis show that under appropriate conditions, such as prices of components and prices of produced fuels, the production of fuels from sewage sludge can be profitable. In the case of PBT fuel, calculated economic indexes show the best profitability for the capacity of a plant over 1.5 t h(-1) output, while production of PBM fuel is beneficial for a plant with the maximum of searched capacities: 3.0 t h(-1). Sensitivity analyses carried out during the investigation show that influence of both technical and economic assessments on the location of maximum of objective function (net present value) is significant. © The Author(s) 2015.

    1999-09-01

    The objective of this work is to show the fundamental decisions that are necessary for planning municipal sewage treatment systems in rural areas and to assess the consequences of the possible alternatives. The analysis shows that the specific costs depend strongly on the chosen technology, the structure of the system and the type of organization. For instance constructed wetlands used on small scales are much more favorable than complex technical sewage plants. Whether a central or decentral structured sewage treatment system is preferable depends on the local topographic conditions. The fact that private and cooperative organizations mostly cause lower costs per capita as public organizations can be explained with the principal-agent-theory of the New Institutional Economics. Further economical and important ecological criteria are discussed in the analysis, too. The conclusions drawn from analysis aim especially to improve the process of planing sewage treatment systems. Especially recommended are the implementation of a professional project management, a complete survey of the given local conditions, the use of modern planning methods, an early participation of the population, the particularly consideration of innovative technologies as well as the development of integrated concepts of water management.

    Finding environmentally benign methods related to sound municipal solid waste (MSW) management is of highest priority in Southeast Asia. It is very important to study new approaches which can reduce waste generation and simultaneously enhance energy recovery. One concrete example of particular significance is the concept of hybrid dual-fuel power plants featuring MSW and another high-quality fuel like natural gas. The hybrid dual-fuel cycles provide significantly higher electrical efficiencies than a composite of separate single-fuel power plant (standalone gas turbine combined cycle and MSW incineration). Although hybrid versions are of great importance for energy conversion from MSW, an economic assessment of these systems must be addressed for a realistic appraisal of these technologies. This paper aims to further examine an economic assessment and energy model analysis of different conversion technologies. Energy models are developed to further refine the expected potential of MSW incineration with regards to energy recovery and environmental issues. Results show that MSW incineration can play role for greenhouse gas reduction, energy recovery and waste management. In Bangkok, the electric power production via conventional incineration and hybrid power plants can cover 2.5% and 8% of total electricity consumption, respectively. The hybrid power plants have a relative short payback period (5 years) and can further reduce the CO 2 levels by 3% in comparison with current thermal power plants.

    Nowadays, there is a concern in development of environmentally friendly methods for a municipal solid waste (MSW) management and demand for renewable energy sources. The source of waste is increasing, and the capacity and availability Landfill treatment and disposal are coming to be insufficient. In Sao Paulo City, the 10 million inhabitants produce 10,000 t of residential solid waste daily, being that 76% this quantity goes to landfill sites. In order to adopt a new treatment technology for MSW that will promote a solution minimizing this problem, within the order of priorities regarding waste management, the MSW incineration with energy recovery shown as the leading choice on the point of view of efficiency in converting energy. MSW incineration with energy recovery received wide acceptance from various countries including European Union members and the rest of the world in the past 15 years. Incineration has the ability decrease 90 % the volume of waste to be used in landfills, increasing the useful life of existing as well as a reduction in the emission of greenhouse gases. MSW incineration systems have a low global warming potential (GWP). now has become a less important source of dioxins and furans due to the current available technology. MSW incineration with energy recovery could contribute considerably in the energy matrix, thus promote the conservation of non-renewable resources. This paper proposes the assessment the technical and economic feasibility of a steam cycle with conventional steam generator for MSW incineration with energy recovery for power generation in Sao Paulo City. Will be developed a thermoeconomic analysis aiming at the total power generation product of MSW incineration, and the assessment investment cost regarding the total sale of power generated. The study shows that Sao Paulo City has potential for power generation from the MSW incineration, although it has a high cost investment this technology shown as a suitable alternative for

    A preliminary process model and techno-economic analysis (TEA) was completed for fuel produced from hydrothermal liquefaction (HTL) of sludge waste from a municipal wastewater treatment plant (WWTP) and subsequent biocrude upgrading. The model is adapted from previous work by Jones et al. (2014) for algae HTL, using experimental data generated in fiscal year 2015 (FY15) bench-scale HTL testing of sludge waste streams. Testing was performed on sludge samples received from MetroVancouver’s Annacis Island WWTP (Vancouver, B.C.) as part of a collaborative project with the Water Environment and Reuse Foundation (WERF). The full set of sludge HTL testing data from this effort will be documented in a separate report to be issued by WERF. This analysis is based on limited testing data and therefore should be considered preliminary. Future refinements are necessary to improve the robustness of the model, including a cross-check of modeled biocrude components with the experimental GCMS data and investigation of equipment costs most appropriate at the smaller scales used here. Environmental sustainability metrics analysis is also needed to understand the broader impact of this technology pathway. The base case scenario for the analysis consists of 10 HTL plants, each processing 100 dry U.S. ton/day (92.4 ton/day on a dry, ash-free basis) of sludge waste and producing 234 barrel per stream day (BPSD) biocrude, feeding into a centralized biocrude upgrading facility that produces 2,020 barrel per standard day of final fuel. This scale was chosen based upon initial wastewater treatment plant data collected by the resource assessment team from the EPA’s Clean Watersheds Needs Survey database (EPA 2015a) and a rough estimate of what the potential sludge availability might be within a 100-mile radius. In addition, we received valuable feedback from the wastewater treatment industry as part of the WERF collaboration that helped form the basis for the selected HTL and upgrading

    This paper shows the results of economic regionalization and zoning of the Republic of Tatarstan, conducted in 2017. The latest experience of economic regionalization and zoning of the Republic of Tatarstan in 2007 - 2015 is exposed. The economic regionalization problem is solved on the basis of new method and algorithm that uses quantitative measures which characterize spatial and economic features of generated economic regions including their internal and average connectivity, homogeneity, compactness, socio-economic development level and life quality of the population. Three nodal and one homogeneous economic region in the Republic of Tatarstan were identified. The results of economic zoning within homogeneous economic region led to the conclusion about two existing economic zones. They have the potential for developing new economic growth pole and three economic centers - growth points with specialization on agro-industrial sector.

    2007-07-01

    The proximity principle - disposing of waste close to its origin - has been a central value in municipal solid waste (MSW) management in Japan for the last 30 years and its widespread adoption has helped resolve numerous "Not in My Backyard" issues related to MSW management. However, MSW management costs have soared, in large part because of aggressive recycling efforts and because most MSW is incinerated in a country that has scarce landfill capacity. In addition, smaller, less sophisticated incinerators have been closed because of high dioxin emissions. Rising costs combined with the closure of smaller incinerators have shifted MSW management policy toward regionalization, which is the sharing of waste management facilities across municipalities. Despite the increased use of regionalized MSW facilities, the proximity principle remains the central value in Japanese MSW management. Municipal solid waste management has become increasingly regionalized in the United States, too, but different driving forces are at work in these two countries. The transition to regionalized MSW management in Japan results from strong governmental control at all levels, with the central government providing funds and policy direction and prefectures and municipalities being the primary implementing authorities. By contrast, market forces are a much stronger force with US MSW management, where local governments - with state government oversight - have primary responsibility for MSW management. We describe recent changes in Japan's MSW programs. We examine the connections between MSW facility regionalization, on the one hand, and, on the other hand, the proximity principle, coordination among local governments, central government control, and financing mechanisms.

    This literature review summarizes and synthesizes the available information regarding the impacts of socioeconomic factors on coastal and watershed restoration in the Puget Sound, Wash. Major topic areas which are explored include: institutions and restoration; beliefs, behaviors, and knowledge about restoration and the environment; stakeholder involvement in restoration, communication of restoration issues, and economic issues in restoration. The review revealed that socioeconomic factors play an important role in determining the designation, process, and success of restoration projects. Socioeconomic factors can facilitate or obstruct restoration, but few large-scale restoration projects emphasize them in either prioritization or monitoring procedures. Additionally, there are substantial gaps in the literature regarding restoration in the Puget Sound across all of the topics addressed in this review. The lack of research makes it difficult to provide a holistic view of the social and economic dimensions of restoration in the Sound but provides opportunity for future research.

    Waste management is something that affects most people. The waste amounts are still increasing, but the waste treatment is changing towards recycling and integrated solutions. In Sweden producers' responsibility for different products, a tax and bans on deposition of waste at landfills implicates a reorganisation of the municipal solid waste management. Plans are made for new incineration plants, which leads to that waste combustion comes to play a role in the reorganisation of the Swedish energy system as well. The energy system is supposed to adapt to governmental decisions on decommission of nuclear plants and decreased use of fossil fuels. Waste from private households consists of hazardous waste, scrap waste, waste electronics and wastes that to a large extent are generated in the kitchen. The latter type has been studied in this thesis, except for newsprint, glass- and metal packages that by source separation haven't ended up in the waste bin. Besides the remaining amount of the above mentioned fractions, the waste consists of food waste, paper, cardboard- and plastic packages and inert material. About 80-90 % of this mixed household waste is combustible, and the major part of that is also possible to recycle. Several systems analyses of municipal solid waste management have been performed. Deposition at landfill has been compared to energy recovery, recycling of material (plastic and cardboard) and recycling of nutrients (in food waste). Environmental impact, fuel consumption and costs are calculated for the entire lifecycle from the households, until the waste is treated and the by-products have been taken care of. To stop deposition at landfills is the most important measure to take as to decrease the environmental impact from landfills, and instead use the waste as a resource, thereby substituting production from virgin resources (avoiding resource extraction and emissions). The best alternative to landfilling is incineration, but also material recycling

    Economic competitiveness is one of the key factors in making decisions towards the development of waste conversion facilities and devising a sustainable waste management strategy. The goal of this study is to develop a framework, as well as to develop and demonstrate a comprehensive techno-economic model to help county and municipal decision makers in establishing waste conversion facilities. The user-friendly data-intensive model, called the FUNdamental ENgineering PrinciplEs-based ModeL for Estimation of Cost of Energy and Fuels from MSW (FUNNEL-Cost-MSW), compares nine different waste management scenarios, including landfilling and composting, in terms of economic parameters such as gate fees and return on investment. In addition, a geographic information system (GIS) model was developed to determine suitable locations for waste conversion facilities and landfill sites based on integration of environmental, social, and economic factors. Finally, a case study on Parkland County and its surrounding counties in the province of Alberta, Canada, was conducted and a sensitivity analysis was performed to assess the influence of the key technical and economic parameters on the calculated results.

    Economic instruments provide significant potential for countries with low municipal waste management performance in decreasing landfill rates and increasing recycling rates for municipal waste. In this research, strengths and weaknesses of landfill tax, pay-as-you-throw charging systems, deposit-refund systems and extended producer responsibility schemes are compared, focusing on conditions in countries with low waste management performance. In order to prioritise instruments for implementation in these countries, the analytic hierarchy process is applied using results of a literature review as input for the comparison. The assessment reveals that pay-as-you-throw is the most preferable instrument when utility-related criteria are regarded (wb = 0.35; analytic hierarchy process distributive mode; absolute comparison) mainly owing to its waste prevention effect, closely followed by landfill tax (wb = 0.32). Deposit-refund systems (wb = 0.17) and extended producer responsibility (wb = 0.16) rank third and fourth, with marginal differences owing to their similar nature. When cost-related criteria are additionally included in the comparison, landfill tax seems to provide the highest utility-cost ratio. Data from literature concerning cost (contrary to utility-related criteria) is currently not sufficiently available for a robust ranking according to the utility-cost ratio. In general, the analytic hierarchy process is seen as a suitable method for assessing economic instruments in waste management. Independent from the chosen analytic hierarchy process mode, results provide valuable indications for policy-makers on the application of economic instruments, as well as on their specific strengths and weaknesses. Nevertheless, the instruments need to be put in the country-specific context along with the results of this analytic hierarchy process application before practical decisions are made. © The Author(s) 2016.

    Full Text Available This feminist study examines the working conditions of preschool teachers, a female dominated occupation, in two municipalities in Iceland and asks, in light of government policy, if and then how the municipalities facilitate preschool teachers professionalism following the 2008 bank collapse. Weber´s (2001 theoretical framework is applied to explore the professional status of the preschools and the impact of local government on preschool teachers’ position. Qualitative methods were used and data was gathered in 2011 and 2012. Thirteen interviews were conducted with women and men in two preschools and the schools administrative environment. Preschool teachers employed in management and non-management positions as well as assistants were interviewed. The study’s results show that financial cutbacks in local government affect preschool teachers and assistants and thus the position of women in the labour market by preserving their subordination. Furthermore, preschool children seem to be affected by the cutbacks which possibly have negative consequences on their well-being. Reforms and developments of the preschool teachers education seem to be met with considerable opposition from local government and more emphasis is placed on operational costs rather than strengthening the preschool teachers in their role as professionals. The results thus point to a gap between government policy and the municipalities’ local version of that same policy.

    A holistic assessment procedure has been used in this study for comparing conventional activated sludge (CAS) and membrane bioreactor (MBR) processes for the treatment of municipal wastewater. Technical, social, administrative, economic and environmental impacts have been evaluated based on 1 year of operational data from three full-scale lines (one MBR and two CAS) working in parallel in a large municipal treatment plant. The comparative assessment evidences a slight advantage of the conventional process in the studied case, essentially due to lower costs, complexity and energy consumption. On the other hand, the MBR technology has a better social acceptance and similar overall environmental footprint. Although these results are influenced by site-specific parameters and cannot be generalized, the assessment procedure allowed identifying the most important factors affecting the final scores for each technology and the main differences between the compared technologies. Local conditions can affect the relative importance of the assessed impacts, and the use of weighting factors is proposed for better tailoring the comparative assessment to the local needs and circumstances. A sensitivity analysis on the weighted final scores demonstrated how local factors are very important and must be carefully evaluated in the decision making process.

    This article describes an accurate methodology for an operational, economic, and environmental assessment of municipal solid waste collection. The proposed methodological tool uses key performance indicators to evaluate independent operational and economic efficiency and performance of municipal solid waste collection practices. These key performance indicators are then used in life cycle inventories and life cycle impact assessment. Finally, the life cycle assessment environmental profiles provide the environmental assessment. We also report a successful application of this tool through a case study in the Portuguese city of Porto. Preliminary results demonstrate the applicability of the methodological tool to real cases. Some of the findings focus a significant difference between average mixed and selective collection effective distance (2.14 km t(-1); 16.12 km t(-1)), fuel consumption (3.96 L t(-1); 15.37 L t(-1)), crew productivity (0.98 t h(-1) worker(-1); 0.23 t h(-1) worker(-1)), cost (45.90 € t(-1); 241.20 € t(-1)), and global warming impact (19.95 kg CO2eq t(-1); 57.47 kg CO2eq t(-1)). Preliminary results consistently indicate: (a) higher global performance of mixed collection as compared with selective collection; (b) dependency of collection performance, even in urban areas, on the waste generation rate and density; (c) the decline of selective collection performances with decreasing source-separated material density and recycling collection rate; and (d) that the main threats to collection route efficiency are the extensive collection distances, high fuel consumption vehicles, and reduced crew productivity. © The Author(s) 2014.

    Full Text Available This issue was carried out in the municipalities of San Pablo Huixtepec, San Sebastián Abasolo and Culiapan of Guerrero as part of the Central Valleys of Oaxaca, Mexico. We studied the production system of Agua Chile, using the technique of structured interview,information was obtained that allowed us to determine and meet the current models of socio-economic benefits in the form of productionof this vegetable. The importance of this study is that the chile de agua despite being a highly profitable crop has been little studied, so it is not known the extent that can have, there are markets that offer potentially greater benefits to farmers, therefore it is important to know the current situation of farmers in order to provide alternatives to improve their economic situation. The results indicate that according to the practices of peasant production and the low level of technology that includes the type of fertilizers, agrochemicals to combat pests and diseases and low use of agricultural machinery, yields of 3.97 t ha-1 allow total revenues are higher than the costs of production. Besides the existence of limited marketing networks (primarily in local markets and in the Oaxaca city, is a competitive crop in terms of profitability for finance of small production units and furthermore, it is growing factor relevant food security of farming families.

    The aim of the present paper is to evaluate cancer survival in patients resident in the municipality of Florence according to different deprivation levels. We used data from the Tuscan Cancer Registry and data from the national census 2001. We used a deprivation index, measured as a continue variable, classified in tertiles according to the distribution of the resident population. We compared more deprived patients (category 3) vs less deprived ones (category 1-2). 10-year relative survival has been computed for patients diagnosed with 27 different cancer sites during 1997-2002, for different deprivation categories. Cancer sites were split into three groups of the same dimension, on the basis of 10-year survival (bad, intermediate and good prognosis). For each category the relative excess risk of death (RER) for most deprived patients has been computed using a Generalized Liner Model. We evaluated also the effect of marital status, classified as married and non-married. We analysed 14 549 invasive cancer cases (out of skin epithelioma). Overall bad prognosis cancers did not show any RER of dying for most deprived patients. For intermediate prognosis cancers RER was 1.13 (1.02 ; 1.24). A excess occurs in the most disadvantaged tertile for tumors diagnosed under 50 years. For good prognosis cancers the RER was 1.06 (0.89 ; 1.26). We found a relative excess of mortality for non-married vs married. In the area of Florence there is an effect of deprivation level of survival for median-better prognosis cancers, for tumours diagnosed under 50 years and for unmarried people compared to unmarried ones.

  6. Municipal Local Economic Development and the Multiplier effect: Piloting a Community Enterprise Identification Method in South Africa and Namibia

    Directory of Open Access Journals (Sweden)

    Lucienne Heideman

    2011-12-01

    Full Text Available Local Economic Development (LED is a contested concept in southern Africa, and has become synonymous with delivery of generic job-creation projects, often grant-dependent and unsustainable. Municipal LED has followed this pattern in South Africa since 1994, with little lasting success. Each local economy is unique, and has its own problems and opportunities. The ’Plugging the Leaks’ method recognizes that communities themselves know best how money enters and exits their area. By asking people to analyse their local economy as a 'leaky bucket', the method puts control back in the hands of local people, rather than external experts, and allows them to analyse their own local economy to identify gaps and opportunities for enterprise. By better networking and working collectively to improve their local economy, local communities are able to re-circulate cash internally. This circulation of cash is explained as the local multiplier effect in the workshops. A pilot process of running ‘Plugging the Leaks’ workshops in low income communities in South Africa and Namibia revealed that spending choices in these communities are severely limited in a context where there is no effective welfare state. Therefore, empowerment with this method came from the discovery of collective action and networking, rather than from individual spending choices. Local start-up business tends to be limited to survivalist and copy-cat one-person ventures, and are a last resort when formal employment is absent. In this context collective enterprise offers the necessary empowerment for people to attempt financially sustainable ventures that respond to a gap in the local economy. The pilot project is attempting to show that municipal LED staff can play the role of facilitator for initiating the enterprise-identification process and further mobilise state enterprise support agencies around the locus of LED, without crossing the line between facilitation and implementation

    After a ban on the depositing of untreated sludge in landfills, the sludge from municipal and industrial water-treatment plants can be regarded as a problem. Waste products of the water treatment process can be a problem or an opportunity - a source for obtaining raw materials. In the European Union, raw sludge and fats, oil and grease (FOG) from municipal and industrial wastewater treatment plants (WWTP) cannot be deposited in any natural or controlled environment. For this reason, it must be processed (stabilized, dried) to be used later as a fertilizer, building material, or alternative fuel source suitable for co-incineration in high temperature furnaces (power plants or concrete plants). The processes of drying sludge, where heat and electricity are used, are energy consuming and economically unattractive. Beside energy efficiency, the main problem of sludge drying is in its variability of quality as a raw material. In addition to this, sludge can be contaminated by a number of organic and inorganic pollutants and organisms. Due to the presence or absence of pollutants, different end products can be economically interesting. For example, if the dried sludge contains coliform bacteria, viruses, helminths eggs or smaller quantities of heavy metals, it cannot be used as a fertilizer but can still be used as a fuel. The objectives of the current article is to present a batch-processing pilot device of sludge or digestate that allows the following: (1) low pressure and low temperature energy effective drying of from 10 to 40% remaining water content, (2) disinfection of pathogen (micro)organisms, (3) heavy metal reduction, (4) production of products of predetermined quality (e.g. containing different quantities of water; it can be used as a fertilizer, or if the percentage of water in the dry sludge is decreased to 10%, then the dried sludge can be used as a fuel with a calorific value similar to coal). An important feature is also the utilization of low

    Full Text Available This paper explores one aspect of early literacy development in a low socio-economic context in South Africa. Assessments conducted with a sample of children from two disadvantaged communities in Cape Town indicated that in this context, almost half of the learners entering Grade One were unable to recognise any letters. A Grade R intervention conducted by volunteers showed that children from this context were able to learn letter-sounds in Grade R through a programme that focused on teaching letter-sounds in the context of building language skills, emergent writing and concepts about print. In order to strengthen the effectiveness of the intervention, the volunteer programme was supplemented by support for the Grade R teacher and teaching assistant. Follow-up assessments of one of the intervention groups at the end of Grade One revealed significant correlations between early Grade One letter knowledge and end of Grade One word reading and spelling skills. The findings of this exploratory study are in line with research that shows the importance of letter-sound knowledge in the earliest stages of learning to read. This raises concerns about the historical lack of emphasis in the Grade R curriculum on this aspect of early literacy development. Although the study has a narrow focus and conclusions cannot be drawn about other aspects of early literacy learning in this context, the results suggest an urgent need for quality Grade R teacher training programmes with a specific focus on emergent literacy.

    The relative economics of radiation treatment and other sludge treatment processes are reported. The desirability of radiation treatment is assessed in terms of cost and the quality of the treated sludge product. The major conclusions of this study are: radiation treatment is a high-level disinfection process. Therefore, it should only be considered if high levels of disinfection are required for widespread reuse of the sludge; the handling, transporting and pathogen growback problems associated with disinfected wet sludge makes it less attractive for reuse than dry sludge; radiation of composted sludge produces a product of similar quality at less cost than any thermal treatment and/or flash drying treatment option for situations where a high degree of disinfection is required; and heavy metal concerns, especially cadmium, may limit the reuse of sludge despite high disinfection levels. It is recommended that radiation treatment of sludge, particularly dry sludge, continue to be studied. A sensitivity analysis investigating the optimal conditions under which sludge irradiation operates should be instigated. Furthermore, costs of adding sludge irradiation to existing sludge treatment schemes should be determined

    Phosphorus (P) is an essential and limited resource. Municipal wastewater is a promising source of P via reuse and could be used to replace P derived from phosphate rocks. The agricultural use of sewage sludge is restricted by legislation or is not practiced in several European countries due to environmental risks posed by organic micropollutants and pathogens. Several technologies have been developed in recent years to recover wastewater P. However, these technologies target different P-containing flows in wastewater treatment plants (effluent, digester supernatant, sewage sludge, and sewage sludge ash), use diverse engineering approaches and differ greatly with respect to P recycling rate, potential of removing or destroying pollutants, product quality, environmental impact and cost. This work compares 19 relevant P recovery technologies by considering their relationships with existing wastewater and sludge treatment systems. A combination of different methods, such as material flow analysis, damage units, reference soil method, annuity method, integrated cost calculation and a literature study on solubility, fertilizing effects and handling of recovered materials, is used to evaluate the different technologies with respect to technical, ecological and economic aspects. With regard to the manifold origins of data an uncertainty concept considering validity of data sources is applied. This analysis revealed that recovery from flows with dissolved P produces clean and plant-available materials. These techniques may even be beneficial from economic and technical perspectives under specific circumstances. However, the recovery rates (a maximum of 25%) relative to the wastewater treatment plant influent are relatively low. The approaches that recover P from sewage sludge apply complex technologies and generally achieve effective removal of heavy metals at moderate recovery rates (~40-50% relative to the WWTP input) and comparatively high costs. Sewage sludge ash is

    A technical, economic and environmental assessment is realized of a thermal treatment technology. The energetic valorization from municipal solid waste and electric power generation in the zone of Los Santos, Costa Rica, are made by the multicriteria hierarchical analysis methodology. The national and cantonal situation is examined in the integral management of municipal solid waste (GIRS), with emphasis on the cantons from the zone of Los Santos. A comparative analysis is developed among some cantons of Costa Rica that have had GIRS studies, and the zone of Los Santos to know the fraction of municipal solid waste that can be valued energetically and calorific power that present. The similarity in the characterization, composition and physico-chemical properties is determined in the study of residues between the cantons analyzed and the zone of Los Santos. The legislation relating the waste processing is analyzed, according Law 8839 for integral management of waste and laws similar to the implementation of a power generation plant. An analysis is developed for the environmental compliance of thermal treatment technologies, including aspects for control of contaminants. The main technologies of energy valorization from waste are investigated and some real cases of Latin America and the world are exposed. A thermal treatment technology of municipal solid waste is selected through a decision-making methodology to evaluate technical, environmental and economic aspects. Operation requirements and functioning of the devices that conform a power generation plant are described by municipal solid waste of the technology selected. The economic viability of the selected proposal has determined by an economic analysis, to extend on the most influential aspects developing alternative scenarios. The diagnosis of the situation of solid waste in the zone of Los Santos has specified that the cardboard, paper and plastics have been the most adequate for the thermal utilization

    A preliminary process model and techno-economic analysis (TEA) was completed for fuel produced from hydrothermal liquefaction (HTL) of sludge waste from a municipal wastewater treatment plant (WWTP) and subsequent biocrude upgrading. The model is adapted from previous work by Jones et al. (2014) for algae HTL, using experimental data generated in fiscal year 2015 (FY15) bench-scale HTL testing of sludge waste streams. Testing was performed on sludge samples received from Metro Vancouver’s Annacis Island WWTP (Vancouver, B.C.) as part of a collaborative project with the Water Environment and Reuse Foundation (WERF). The full set of sludge HTL testing data from this effort will be documented in a separate report to be issued by WERF. This analysis is based on limited testing data and therefore should be considered preliminary. In addition, the testing was conducted with the goal of successful operation, and therefore does not represent an optimized process. Future refinements are necessary to improve the robustness of the model, including a cross-check of modeled biocrude components with the experimental GCMS data and investigation of equipment costs most appropriate at the relatively small scales used here. Environmental sustainability metrics analysis is also needed to understand the broader impact of this technology pathway. The base case scenario for the analysis consists of 10 HTL plants, each processing 100 dry U.S. ton/day (92.4 ton/day on a dry, ash-free basis) of sludge waste and producing 234 barrel per stream day (BPSD) biocrude, feeding into a centralized biocrude upgrading facility that produces 2,020 barrel per standard day of final fuel. This scale was chosen based upon initial wastewater treatment plant data collected by PNNL’s resource assessment team from the EPA’s Clean Watersheds Needs Survey database (EPA 2015a) and a rough estimate of what the potential sludge availability might be within a 100-mile radius. In addition, we received

    A strategy is proposed for deployment of an advanced nuclear-electric power sector that is ultimately fueled only by recycled uranium. The sector is optimized on a system basis to meet several objectives in the context of international safeguards against diversion of plutonium and proliferation of nuclear weapons. These objectives include: generation of electric power efficiently and economically; performance with utmost predictable safety; minimization of environmental impacts through conservation of natural resources, consumption of actinides and long-lived fission products, and responsible disposal of unavoidable waste; and consumption of spent fuel from currently used reactors.

    2007-06-01

    Assessment and economic valuation of services provided by ecosystems to humans has become a crucial phase in environmental management and policy-making. As primary valuation studies are out of the reach of many institutions, secondary valuation or benefit transfer, where the results of previous studies are transferred to the geographical, environmental, social, and economic context of interest, is becoming increasingly common. This has brought to light the importance of environmental valuation databases, which provide reliable valuation data to inform secondary valuation with enough detail to enable the transfer of values across contexts. This paper describes the role of next-generation, intelligent databases (IDBs) in assisting the activity of valuation. Such databases employ artificial intelligence to inform the transfer of values across contexts, enforcing comparability of values and allowing users to generate custom valuation portfolios that synthesize previous studies and provide aggregated value estimates to use as a base for secondary valuation. After a general introduction, we introduce the Ecosystem Services Database, the first IDB for environmental valuation to be made available to the public, describe its functionalities and the lessons learned from its usage, and outline the remaining needs and expected future developments in the field.

    As society evolves its welfare level increases, and as a consequence the amount of municipal solid waste increases, imposing great challenges to municipal authorities. In developed countries, municipalities have established integrated management schemes to handle, treat, and dispose of municipal solid waste in an economical and environmentally sound manner. Municipalities of developing and transition countries are not exempted from the challenges involving municipal solid waste handling, but their task is not easy to accomplish since they face budget deficits, lack of knowledge, and deficiencies in infrastructure and equipment. In the northern territory of Mexico, the municipality of Durango is facing the challenge of increased volumes of waste with a lack of adequate facilities and infrastructure. This article analyses the evolution of the municipal solid waste management of Durango city, which includes actions such as proper facilities construction, equipment acquisition, and the implementation of social programmes. The World Bank, offering courses to municipal managers on landfill operation and waste management, promoted the process of knowledge and technology transfer. Thereafter, municipal authorities attended regional and some international workshops on waste management. In addition they followed suggestions of international contractors and equipment dealers with the intention to improve the situation of the waste management of the city. After a 15-year period, transfer of knowledge and technology resulted in a modern municipal solid waste management system in Durango municipality. The actual system did not reach the standard levels of an integrated waste management system, nevertheless, a functional evaluation shows clear indications that municipality actions have put them on the right pathway. © The Author(s) 2014.

    There is no difference in principle between the infrasonic and ultrasonic sounds, which are inaudible to humans (or other animals) and the sounds that we can hear. In all cases, sound is a wave of pressure and particle oscillations propagating through an elastic medium, such as air. This chapter...... is about the physical laws that govern how animals produce sound signals and how physical principles determine the signals’ frequency content and sound level, the nature of the sound field (sound pressure versus particle vibrations) as well as directional properties of the emitted signal. Many...... of these properties are dictated by simple physical relationships between the size of the sound emitter and the wavelength of emitted sound. The wavelengths of the signals need to be sufficiently short in relation to the size of the emitter to allow for the efficient production of propagating sound pressure waves...

    Full Text Available One way that helps maintain the sustainability of agro-ecosystems land is the application of compost from municipal solid waste as fertilizer, because it can recover the nutrients contained in them, minimizing the negative impact on the environment. Composting as a method for preparing organic fertilizers and amendments is economically and ecologically sound and may well represent an acceptable solution for disposing of municipal solid waste. In the present work, the quality of compost is studied made from municipal solid waste; the content of mineral nutrients: potassium, calcium, magnesium, sodium, zinc, manganese, cupper, iron, nickel, chromium and lead has been investigated. The objective was to evaluate the changes in mineral nutrient concentration during the composting process. The compost was prepared in a pilot-plant using the turning-pile system. Temperature was used as a monitoring parameter to follow the composting progress, which underwent the typical trend of municipal solid waste composting mixtures. The results showed a similar evolution on the content of mineral nutrients of the mixture of municipal solid waste. This evolution originated in a mature compost (end sample with an adequate content of mineral elements and physical-chemical characteristics for its use in agriculture. So, the use of compost of municipal solid waste represents an important tool for fertilization requirements for its use in agriculture.

    Full Text Available This paper discusses the relationship between the levels of investment in health and education made by the municipalities and the collection of property taxes. A data panel methodology was used with a sample of 97 municipalities in the department of Antioquia (Colombia for the period 2000 - 2008. According to the results, it is possible to conclude that there is no relationship between the levels of autonomous investment in education and the collection of property taxes. On the other hand, in relation to health investments, a negative relationship was found between property tax collection and autonomous investment in health. Finally, in addition to the initial scope proposed, a positive relationship was shown between the collection of property taxes and investments in the development of roads and infrastructure.

    At present acquiring safe drinking water in rural or remote areas of Pakistan is a challenging task for dwellers. Coast line of Karachi is a sporadic habitat of villages not having access to safe drinking water. Many incidents of waterborne diseases have been reported in that area and attributed to contaminated municipal water supply. Solution of the problem is disinfection however, general methods of water disinfection such as boiling, UV-lamp, ozonation and chemical additive are costly or require skilled manpower. Present study investigates the solar disinfection method to treat municipal water supply at Karachi Institute of Power Engineering (KINPOE) located at the coastal belt of Karachi. Effect of exposure time, bottle material and turbidity of water on the process performance was evaluated. Model indicator bacteria total coliform (TC) was used to evaluate the solar disinfection process. Study revealed that in order to disinfect the municipal water, samples should be filled in PET transparent bottles, having turbidity below 23 NTU, and expose to solar radiation in the study area at least for one hour. Study shows that solar disinfection may provide safe drinking water meeting national and international water quality standards at minimum cost and effort in sunshine rich areas and not having access to other water purification systems.

    Full Text Available The disposal of solid residues has been a critical factor in urban management. Sanitary landfilling treatment systems predominate, but new alternatives have been developed, supported by high-tech. Nevertheless, financial investment exerts a strong restriction to that choice. Thus, is it economically viable to implement an Alfa equipment to replace sanitary landfills? This study aimed to measure the costs of landfilling and to implement a heat treatment system. The methodology was an applied and exploratory research characterized as a case study in the municipality of Marechal Cândido Rondon, in the State of Paraná. The results demonstrate that such a replacement is not economically viable, and sanitary landfilling is still the chosen method.. The new technology has a great environmental and social potential, essentially in the cities where physical space is very restricted or costly.

    Highlights: • 3E impact of WTE derived from MSW were performed. • MSW treatment technologies significantly effects the economic and environmental benefits of WTE. • Different scenarios are conducted based on the waste projections and production. • Comprehensive discussion on the trade-off of both incineration and anaerobic digestion for MSWM. - Abstract: The utilisation of municipal solid waste (MSW) for energy production has been implemented globally for many decades. Malaysia, however, is still highly dependent on landfills for MSW management. Because of the concern for greenhouse gases (GHG) emission and the scarcity of land, Malaysia has an urgent need for a better waste management strategy. This study aims to evaluate the energy, economic and environmental (3E) impact of waste-to-energy (WTE) for municipal solid waste management. An existing landfill in Malaysia is selected as the case study for consideration to adopt the advanced WTE technologies including the landfill gas recovery system (LFGRS), incineration, anaerobic digestion (AD), and gasification. The study presented an interactive comparison of different WTE scenarios and followed by further discussion on waste incineration and AD as the two potential WTE options in Malaysia. The 3E assessment reveals incineration as the superior technology choice when the production of electricity and heat were considered; however, AD is found to be more favourable under the consideration of electricity production only

    Gold mining has played an important role in Ghana’s economy, however the negative environmental and socio-economic effects on the host communities associated with gold mining have overshadowed these economic gains. It is within this context that this paper assessed in an integrated manner the environmental and socio-economic impacts of artisanal gold mining in the Tarkwa Nsuaem Municipality from a natural and social science perspective. The natural science group collected 200 random samples on bi-weekly basis between January to October 2013 from water bodies in the study area for analysis in line with methods outlined by the American Water Works Association, while the social science team interviewed 250 residents randomly selected for interviews on socio-economic issues associated with mining. Data from the socio-economic survey was analyzed using logistic regression with SPSS version 17. The results of the natural science investigation revealed that the levels of heavy metals in water samples from the study area in most cases exceeded GS 175-1/WHO permissible guideline values, which are in tandem with the results of inhabitants’ perceptions of water quality survey (as 83% of the respondents are of the view that water bodies in the study area are polluted). This calls for cost-benefits analysis of mining before new mining leases are granted by the relevant authorities. PMID:26821039

    Full Text Available The aim of this study was to verify possible differences in the levels of physical activity related to the socio-economic conditions of schoolchildren in the municipality of Santa Cruz do Sul-RS. It is of transversal-descriptive character, and its subjects are 350 schoolchildren, aged 7 to 17, of both genders. For data collection a previously validated and adapted questionnaire was used, while the chi-quadrat-test was used for statistical analysis. Significant statistical differences were detected in the manner of locomotion, with regard to the school level and socio-economic status, for both genders. The results showed that students from urban areas and of inferior socio-economic levels showed more active in this respect. In the practice of physical activities, the results pointed to a reverse relation of this variable with the socio-economic level. At school level, a prevalence of inactive subjects from the rural area was observed. The difference in the form of locomotion and the physical activities of the evaluated schoolchildren, both at school level and at their socio-economic level, demonstrates different profiles of schoolchildren, which should be considered in future intervention programs.

    The business case for climate protection activities is like a road map, indicating the right direction to go in. It estimates how long it will take to achieve desired results and highlights possible obstacles. Triple bottom line accounting considers all economic, environmental, and social factors of any given project. It is used by municipal governments to create these road maps. Sound fiscal management is addressed by clearly showing how to reduce costs, improve service delivery, create jobs and support local industries, while also protecting human health and the environment. For example, money can be saved and air pollution can be reduced by reducing energy consumption in a municipal building. Staff absenteeism can be reduced through improved air quality. The Federation of Canadian Municipalities has introduced a Partners for Climate Protection (PCP) initiative which guides municipal governments through steps leading to the development of a business case. 21 refs.

    Full Text Available Decision-making for the selection of treatment alternatives and landfilling of municipal solid waste (MSW is based on the experience and judgment of those management responsible, without considering multicriteria analysis. Therefore, the purpose of this research was to determine the treatment scenario and landfilling of MSW with the lowest environmental and economic costs in a medium-sized city. The methodology included the definition and data processing of the project (population, generation, and composition of MSW, for 16 years. In the design of scenarios, recycling, composting, incineration with energy recovery, and landfilling treatments were proposed; later, the combinations of treatments for each type of residue were generated. The results showed 36 scenarios, then the ELECTRE method was applied to the five with the lowest economical and environmental costs. Finally from the latter, one dominant scenario was determined: organic waste in composting; plastic, paper, and glass in recycling; and ‘others’ in landfilling. It is concluded that the final decision on the scenario is adapted to the particular conditions of the locality.

    Waste causes environmental pollution and greenhouse gas (GHG) emissions when it is not managed sustainably. In Bangladesh, municipal organic waste (MOW) is partially collected and landfilled. Thus, it causes deterioration of the environment urging a recycle-oriented waste management system. In this study, we propose a waste management system through pyrolysis of selective MOW for biochar production and composting of the remainder with biochar as an additive. We estimated the carbon (C), nitrogen (N), phosphorus (P) and potassium (K) recycling potentials in the new techniques of waste management. Waste generation of a city was calculated using population density and per capita waste generation rate (PWGR). Two indicators of economic development, i.e., gross domestic product (GDP) and per capita gross national income (GNI) were used to adopt PWGR with a projected contribution of 5-20% to waste generation. The projected PWGR was then validated with a survey. The waste generation from urban areas of Bangladesh in 2016 was estimated between 15,507 and 15,888 t day -1 with a large share (∼75%) of organic waste. Adoption of the proposed system could produce 3936 t day -1 biochar blended compost with an annual return of US $210 million in 2016 while it could reduce GHG emission substantially (-503 CO 2 e t -1 municipal waste). Moreover, the proposed system would able to recover ∼46%, 54%, 54% and 61% of total C, N, P and K content in the initial waste, respectively. We also provide a projection of waste generation and nutrient recycling potentials for the year 2035. The proposed method could be a self-sustaining policy option for waste management as it would generate ∼US$51 from each tonne of waste. Moreover, a significant amount of nutrients can be recycled to agriculture while contributing to the reduction in environmental pollution and GHG emission. Copyright © 2018 Elsevier Ltd.

    Full text of publication follows. The decommissioning of the Vandellos-I nuclear power plant was a big challenge for the host community of Vandellos i l'Hospitalet de l'Infant and the close-by region. Closing down of the facility resulted in a rise of unemployment and a decrease of municipal income. The public was concerned with three issues: safety, transparency and information about the decommissioning, and economic future. Therefore, from the very beginning, municipal governments entered into negotiations with ENRESA on socio-economic benefits, including local employment in dismantling activities, and other types of financial and non-financial compensation. The ADE business association, i.e. a network of business organisations was created that guided the allotment of work to local firms. To satisfy public demand, local municipalities focused on the triad of safety, dialogue and local development, considered the three 'pillars of trust'. A Municipal Monitoring Commission was created, made up of representatives of affected municipalities, the regional government, the ADE business association, trade unions, the local university, the NPP management and ENRESA to monitor the dismantling process and regularly inform the local public. Items that were handled by this Commission included: - Work process monitoring. - Workers. - Materials Control. - Conventional and radioactive or contaminated waste management. - Emanation waste management (liquid and gas) - Safety (training and accidents). - Surveillance (radiological and environmental: dust, noise). - Effects. - Fulfillment of agreed conditions. A number of communication tools and channels were used, e.g., public information meetings, an information centre, the municipal magazine, the municipal radio station, and meetings with representatives of the local press. Particularly innovative was the idea to ask academics from the University of Tarragona to help with 'translating' technical information into language that could

    The objective of this paper is to assess the technical and economic feasibility of a new process for co-liquefying coal and plastic wastes. This assessment is based on incorporating recent experimental data on plastic/coal liquefaction within a conceptual process framework. A preliminary design was developed for two process configurations. The primary difference between the configurations is the source of hydrogen (coal versus cellulosic waste). The assessment was based on co-liquefying 720 tons per day of plastic waste with an equivalent amount of coal on a weight basis. The plant products include hydrocarbon gases, naphtha, jet fuel and diesel fuel. Material and energy balances along with plant-wide simulation were conducted for the process. Furthermore, the data on plastic-waste availability, disposal and economics have been compiled. The results from the economic analysis identify profitability criteria for gross profit and thus return on investment based on variable conversion, yield and tipping fee for plastic waste processed. 11 refs., 6 figs

    Brazil's Unified National Health System is financed according to a model known as fiscal federalism, the fund-sharing rules of the Social Security Budget, Ministry of Health norms, and Constitutional Amendment 29 (EC-29), which links Federal, State, and municipal resources to health. This article discusses the sustainability of public spending on health at the municipal level. Twenty-one municipalities were studied, using municipal budget data. From 1996 to 2006, total current per capita revenues increased by 280% above the accumulated inflation and Gross Domestic Product, varying by size of municipality, which also defined the composition of the municipal budgets. Meanwhile, the budget comprising the basis for EC-29 increased less (178%), thus placing limits on the municipal share of health spending. The results observed in these municipalities are believed to reflect the reality in thousands of other Brazilian municipalities, thus jeopardizing the capacity for municipal investment in health, especially beginning in 2008. The situation may become even worse, considering the repeal of the so-called Bank Transaction Tax (CPMF), Bills of Law 306/08 and 233/08 (currently under review in the National Congress), and the world recession stemming from the U.S. financial crisis.

    The panel discussing market opportunities for municipal electric companies was moderated by Markham Mayor Don Cousens. He expressed himself in favour of deregulation and was optimistic about the benefits it will bring to municipal electric utilities and their customers. Barry Chuddy, General Manager of Business Development for TransAlta Energy discussed the advantages of recent cogeneration and district energy for municipal utilities in Ontario and Quebec, and expressed his support for incentive-based regulation based on a level playing field, competitive generation, and a reasonable charge for stranded assets. Toronto City Councillor Dan Leckie described cogeneration and district energy as a tremendous opportunity to reduce the cost of doing business in the city core through local job creation and by keeping money in the local economy. Karl Wahl, General Manager of Hydro Mississauga expressed optimism that the government will move expeditiously toward competition, choice and lower-cost supply.

    Nowadays the treatment of the solid and liquid remainders in the municipal slaughter houses is small because of the idea that the treatment is expensive; nevertheless, it is important to take advantage of them, since this can reduce to the environmental impacts they cause, as well as the discharge of greenhouse effect gas. The use of bio digesters for the treatment of these remainders has become an efficient process to avoid the exit of methane gas to the atmosphere, taking advantage of the biogas and other residues to produce electricity. The elaboration of a technical-economical evaluation of a pilot plant shows the costs of investment, maintenance, as well as the income that can be obtained by the total usage of these residues and the savings in the electrical power consumption. The analysis of this study demonstrates that the use of biogas through bio-digesters for the generation of electrical energy is a profitable option for the treatment of the residues, because the income by the sale of compost, blood flour, as well as the diminution of the electrical tariff, justifies the initial investment. These projects will be more attractive, if they use financing and are registered as MDL projects.

    Emergy Accounting and Synthesis, developed by Howard Odum in the 1980s, accounts for both the work of nature and that of humans as part of it in generating products and services. Since the 1990s, when Odum's system theories and emergy approach were introduced to China, a great attention was paid to them, since they appeared to Chinese scholars very important, comprehensive, and rich with application opportunities to China's economic development and environmental management. Until now more than 150 papers related to emergy theories were published in Chinese scientific journals, more than 20 dissertations presented in all Chinese Universities, and a large number of emergy-based papers were authored by Chinese scholars in international journals. Also, several reports dealing with emergy evaluation of different provinces of China were presented to local governments for decision-making. Emergy theories were applied to valuation of ecosystems and eco-industrial parks, as well as to studies of benefits/cost analysis and feasibility of ecological engineering. Meanwhile, a series of monographs and translated books related to emergy theories were published in China, some of which are used as text books in Chinese universities and institutes. Compared with the great potential of emergy application, there are many new fields that should be addressed in China, including: assessing the environmental impact of processes based on matching of high-quality and low-quality resources, establishing new frameworks and systems for environmental accounting, evaluating natural capital and services and applying research results to the process of decision-making, and finally studying the patterns and the available development options of China regional eco-economic systems.

To argue this, we look at the evidence from auditory science, neuroscience, and philosophy, briefly present some new conceptual thinking on sound...... that accounts for this view, and then use this to look at what the future might hold in the context of imagining sound and developing technology....

    Limited to insufficient land resources, incinerators are considered in many countries such as Japan and Germany as the major technology for a waste management scheme capable of dealing with the increasing demand for municipal and industrial solid waste treatment in urban regions. The evaluation of these municipal incinerators in terms of secondary pollution potential, cost-effectiveness, and operational efficiency has become a new focus in the highly interdisciplinary area of production economics, systems analysis, and waste management. This paper aims to demonstrate the application of data envelopment analysis (DEA) - a production economics tool - to evaluate performance-based efficiencies of 19 large-scale municipal incinerators in Taiwan with different operational conditions. A 4-year operational data set from 2002 to 2005 was collected in support of DEA modeling using Monte Carlo simulation to outline the possibility distributions of operational efficiency of these incinerators. Uncertainty analysis using the Monte Carlo simulation provides a balance between simplifications of our analysis and the soundness of capturing the essential random features that complicate solid waste management systems. To cope with future challenges, efforts in the DEA modeling, systems analysis, and prediction of the performance of large-scale municipal solid waste incinerators under normal operation and special conditions were directed toward generating a compromised assessment procedure. Our research findings will eventually lead to the identification of the optimal management strategies for promoting the quality of solid waste incineration, not only in Taiwan, but also elsewhere in the world.

    From new years, also in Italy is increasing the awareness of the not deferability of the problems about energetic consumption and with environmental pollution. In this contest, in the present note it's pointed out the risk of the sell of unloading of the MSW (Municipal Solid Wastes) and also the importance of legislative directions promulgate recently to face correctly the problem. In this work is considered the qualitative-quantitative aspects of the municipal solid wastes in the province of Cosenza with some reference to the experiences made in this sector. It's also shown that a MSW incinerator with energy recovery is principally characterized for a strong contribution to the environmental healing and, in second step, but not less important, for a energetic saving of the fossil fuels [it

    Science.gov (United States)

    Fuchs, H. V.; Möser, M.

    Sound absorption indicates the transformation of sound energy into heat. It is, for instance, employed to design the acoustics in rooms. The noise emitted by machinery and plants shall be reduced before arriving at a workplace; auditoria such as lecture rooms or concert halls require a certain reverberation time. Such design goals are realised by installing absorbing components at the walls with well-defined absorption characteristics, which are adjusted for corresponding demands. Sound absorbers also play an important role in acoustic capsules, ducts and screens to avoid sound immission from noise intensive environments into the neighbourhood.

    The aim of this study is to give an up-to-date assessment of the effects the construction of the final disposal facility for spent nuclear fuel in Eurajoki, based on latest knowledge. The disposal facility's effects on employment, population, housing construction, community structure and economy are estimated in the municipality of Eurajoki and in the wider region under the influence of the facility. The time-span of the report reaches from 2001 to the early 2020's when the facility will be in operation. The investment in research and construction of the disposal facility during the years 2004-2020 will be all together approximately 290 million euros. The estimation for the overall effect on national employment during the years 2001-2020 is circa 6 800 manyears, of which 4 200 man-years are from direct effects and 2 600 from indirect effects. The direct employment effects of the project will be at its highest approximately 325 man-year per year in 2020. The direct effect on employment during the operational period is estimated to be circa 130 man-years per year, of which the share of regular employees of Posiva is slightly over 100 man-years. At its highest, about 45 man-years per year of the total effect on employment (direct + indirect effects) will be directed to Eurajoki municipality. During the operational phase the share of Eurajoki is estimated to be circa 30 man-years per year. For the whole region, the effect of the disposal facility on employment will be significant, at its height in 2020, approximately 220 man-years per year. The disposal facility will also have an effect on the size and the structure of the population due to changes in employment and jobs. The estimation for the cumulative effect on the growth of the population caused by the facility is 80 more inhabitants in Eurajoki by 2020, which corresponds to 1,4 % of the municipality's current population. The growth of the population brought about by the facility in the whole region is estimated

    The challenges and special issues which arise through the sale of a municipal electric utility were discussed. The recent sales of two utilities, the Kentville Electric Commission in Nova Scotia and Cornwall Electric in Ontario, were used as examples to show how the sale of an electric utility differs from the sale of most business enterprises. Municipal utilities are integral parts of the communities they serve which introduces several complexities into the sale. Factors that require special attention in the sale of the utilities, including electricity rates, local accountability, treatment of employees and local economic development, and the need for a comprehensive communication program to deal with the substantial public interest that sale of a municipal utility will engender, were reviewed

    In terms of the Law nr. 9.478 of August 6{sup th}, 1997, called Petroleum Law, all rights to oil and natural gas Exploration and Production - E and P on Brazil territory, are federal property, and is administered by the National Petroleum, Natural Gas and Biofuels Agency - ANP. The E and P activities are carried out since 1998 through concession contracts, preceded by tender, as established by the above mentioned law. The concession contract disposes on the government participation, including signature bonus; royalties; special participation; and fees for the occupation or retention of area, which are distributed to Federal, States and Municipalities institutions. The royalties are paid monthly in local currency, as from date of the start up of the commercial production of each field, in an amount corresponding to 10% (ten percent) of the production of oil or natural gas. In case of a large production volume, or great profitability, the concessionaires must to pay a special participation regulated by Presidential Decree This work presents the evaluation of Social-Economic Development Impact of the E and P Onshore Activities in Brazilians Municipalities, regarding the performance of local Gross Domestic Product - GDP and the Human Development Index - IDH in these areas. For that, it is used the Differences-in-Differences Estimator - DD and an Artificial Neural Networks as general non-linear function approximation. The results, in both methodologies, confirm the importance of E and P activities to municipal economy and for its social development, despite the short period in force of the Law and the IDH database used, 1991 and 2000.

    Full Text Available Modern society is characterised not only by a fascination with scientific technology as a means of solving all problems, especially those that stand in the way of material progress (technicism, but also by an obsessive interest in everything that has to do with money (economism or mammonism. The article discusses the relationship between technicism and economism, on the basis of their relationship to utilitarian thinking: the quest for the greatest happiness for the greatest number of people. Recent major studies of neo-liberalism (seen as an intensification of utilitarianism by Laval and Dardot are used as reference to the development of utilitarianism. It is suggested that the western view of the world, as expressed in economism and technicism, with a utilitarian ethics, features three absolutisations: those of theoretical thinking, technology and economics. In a second part, the article draws on the framework of reformational philosophy to suggest an approach that, in principle, is not marred by such absolutisations.

    Sound zones, i.e. spatially confined regions of individual audio content, can be created by appropriate filtering of the desired audio signals reproduced by an array of loudspeakers. The challenge of designing filters for sound zones is twofold: First, the filtered responses should generate...... an acoustic separation between the control regions. Secondly, the pre- and post-ringing as well as spectral deterioration introduced by the filters should be minimized. The tradeoff between acoustic separation and filter ringing is the focus of this paper. A weighted L2-norm penalty is introduced in the sound...

    Full Text Available The developing countries, especially in the Balkans, barely use the municipal bonds as an alternative way of financing their activities. This paper is part of the project “The municipal bonds as an alternative source of financing municipals activities and the effective management of funds, with a special emphasis to the Municipality of Stip, R. Macedonia”. The paper has an important impact, according to both academic and practical perspective. It combines the experts’ academic analysis with the municipals potential in order to facilitate a successful municipal bond emission that would support the local economic growth. The purpose of this paper is to investigate the ability and willingness of the Municipality of Stip to issue municipal bonds. The main hypothesis states that the Municipality of Stip is able to issue a municipal bond as an alternative way of financing its investment activities. The research includes the classical SWOT analysis regarding the Municipality of Stip and continues with a statistical analysis based on correlation and regression relationships within the accounts of the Municipality’s annual reports. The methodological framework is based on quantitative research methods (correlations and regression methods which result in acceptance of the main hypothesis in the paper - the municipal bonds as an alternative source for funding municipal’s activities are justified, especially if the funds are associated with a specific revenue-generating project. The findings would serve as a basis for the municipal bonds prospect, which would be the ultimate goal of combining the academic knowledge with the practical potential of the Municipality of Stip. The conclusions reveal that this would be the first municipal bond emission in the Republic of Macedonia. However, this fact can serve as an advantage in the market in terms of introducing financial instrument innovation. This paper suggests that the usage of municipal bonds is

  5. Municipal Governments and Development in Latin America

    1999-10-01

    Full Text Available The processes of democratization, State reforms and administrative de-concentration that have marked the last 15 years of Latin American societies have brought about a reevaluation of the role of municipalities. The decentralization of the State has been put forth as basic objective and the economic productive restructuring happening around the world calls for a response from local initiatives: that is to say, initiatives to effect a new strategy of development “from the bottom up” that values territory as a geographic space bounded by a community of interests. One of the important actors in these local initiatives are the municipal governments who, as a first government resort, must respond to the vast demands of the population. These institutions are not consolidated, however. Instead, they are generally weak, with little economic, political and ideological power, and are limited in their autonomy, authority, legitimacy and capacity for management. In the first part of the article, and in an effort to characterize the political autonomy of the region’s municipalities, their distinct elements are analyzed – the system of representative democracy, competencies and resources, etc.. The most notorious deficiencies of Latin American municipalities are also studied. The second section analyzes the roles that these municipalities should take on to overcome these deficiencies, and goes on to offer action proposals towards creating a new model for municipal management, new ways of making policy from the municipality, and an analysis of the different instruments for promoting the local economy.

    Wambach, J.

    1991-01-01

    Nuclei, like more familiar mechanical systems, undergo simple vibrational motion. Among these vibrations, sound modes are of particular interest since they reveal important information on the effective interactions among the constituents and, through extrapolation, on the bulk behaviour of nuclear and neutron matter. Sound wave propagation in nuclei shows strong quantum effects familiar from other quantum systems. Microscopic theory suggests that the restoring forces are caused by the complex structure of the many-Fermion wavefunction and, in some cases, have no classical analogue. The damping of the vibrational amplitude is strongly influenced by phase coherence among the particles participating in the motion. (author)

  17. PREFACE: Aerodynamic sound Aerodynamic sound

    Science.gov (United States)

    Akishita, Sadao

    2010-02-01

    The modern theory of aerodynamic sound originates from Lighthill's two papers in 1952 and 1954, as is well known. I have heard that Lighthill was motivated in writing the papers by the jet-noise emitted by the newly commercialized jet-engined airplanes at that time. The technology of aerodynamic sound is destined for environmental problems. Therefore the theory should always be applied to newly emerged public nuisances. This issue of Fluid Dynamics Research (FDR) reflects problems of environmental sound in present Japanese technology. The Japanese community studying aerodynamic sound has held an annual symposium since 29 years ago when the late Professor S Kotake and Professor S Kaji of Teikyo University organized the symposium. Most of the Japanese authors in this issue are members of the annual symposium. I should note the contribution of the two professors cited above in establishing the Japanese community of aerodynamic sound research. It is my pleasure to present the publication in this issue of ten papers discussed at the annual symposium. I would like to express many thanks to the Editorial Board of FDR for giving us the chance to contribute these papers. We have a review paper by T Suzuki on the study of jet noise, which continues to be important nowadays, and is expected to reform the theoretical model of generating mechanisms. Professor M S Howe and R S McGowan contribute an analytical paper, a valuable study in today's fluid dynamics research. They apply hydrodynamics to solve the compressible flow generated in the vocal cords of the human body. Experimental study continues to be the main methodology in aerodynamic sound, and it is expected to explore new horizons. H Fujita's study on the Aeolian tone provides a new viewpoint on major, longstanding sound problems. The paper by M Nishimura and T Goto on textile fabrics describes new technology for the effective reduction of bluff-body noise. The paper by T Sueki et al also reports new technology for the

    Karhu, V.; Nissinen, T.; Valkama, P.

    1999-01-01

    The objective of the empirical part of the study (Chapter 6) is to evaluate the equitableness of profits on capital invested of the 16 municipal energy boards selected for this study and, at the same time, to create a general evaluation basis for equity decisions made by the authorities case by case. In this part of the study, answers are sought for the following questions: (1) how has the economic situation of the energy boards studied been recently developing based on various economic parameters? (2) have there been differences in the returns and profitability of energy boards operating as public utilities or energy boards operating in company form? (3) what kind of a price level the energy boards studied have maintained in relation to the national averages of this field? (4) is a city in a weaker economic position more tempted to require higher profits on capital invested than a city with a sound economic basis? (5) how high profits on capital invested can be considered reasonable for the whole energy board and particularly for a network business holding a monopoly? The structure of the study is as follows. Chapter 2 contains a brief description of the energy boards selected for this study and of the economic situation of the cities owning them. The theoretical part of the study is included in Chapter 3 'Municipal Self-Government and Business'. It analyses rather deeply the terminology of the municipal business, norm basis, steering of actions, restructuring of companies into business profit centres and privatisation, as well as application of the Act on Restrictions on Competition from the standpoint of a municipal self-government. Chapter 4 deals with the establishment of energy board activity, the legal basis and the criteria for pricing electricity, network services and district heat.

    Objective of the study is measuring economy feasibility of Kridosono urban park as a public goods that expected directly addresses the issues of natural environmental quality. Data were obtained from interviews toward local resident of Yogyakarta municipality. Hereafter, willingness to pay (WTP toward demand models were estimated by contingent valuation method (CVM and used to derive total consumer surplus. The results indicate that economic value of Kridosono Stadium land is about US$ 27 million (IDR 257 billion per annum, more than its market price i.e. amount US$ 7.8 million or IDR 74 billion. Thus, the study gives stakeholders knowledge of decision making for managing, funding and alocating resources. Utilization part of Kridosono Stadium land as urban park will give bigger benefit than it would be this for commercial interest. Auspicious is hanging on the urban park, because it will help eliminate greenhouse gases i.e. Carbon dioxide, Methane, Nitrous oxide, Hydro-fluorocarbons, Perflurocarbon and Sulfur hexafluoride which is produced by motor vehicle.

    Full Text Available ABSTRACT: The objective of this study was to evaluate the economic benefit of coffee cultivation, with a focus on the distinction between conventional and irrigated coffee production systems. For the development of the study, the various productive systems were delineated from the data provided by a sample of producers to generate a matrix of average technical coefficients. The methodology used to estimate the operating cost of production is the one used by the Instituto de Economia Agrícola (IEA. Profitability indicators were also evaluated. Results indicated that the effective operational cost (EOC incurred in the irrigated production system is higher than that in the conventional system. As regards the cost composition, in the conventional coffee production system, the largest cost incurred is on fertilizers among all inputs, whereas in the irrigated production system, the largest cost incurred is on machinery and equipment that are mainly used in harvesting, for the period 2013-2015. Profitability index of the conventional coffee production system in 2015 was 44.8%, and that of the drip irrigated production system was 49.7%. In 2014, profitability rates were negative for both the conventional (-13.9% and irrigated coffee production systems (-8.6%. The most preferable choice was found to be the irrigated production system, as it allows reducing the risk of loss in production during prolonged periods of water shortage as well as greater yields due to a larger production of grains.

    2014-03-01

    Full Text Available The goal of the article is justification of the necessity of legal regulation of actions of the bodies of local self-government when detecting signs of insolvency. Each stage of municipal loans management is analysed from the point of view of availability of legal rules, which do not allow making municipal loans by territorial communities of the cities with weak financial state or regulate sequence of actions of municipalities in default times. The following results were obtained: majority of legal restrictions in the sphere of local finance management are directed at prevention of ungrounded loans or have the form of sanctions, applied to local bodies, which perform their debt obligations with delay; the state formally controls the process of making municipal loans, avoiding financial responsibility; the national legislation does not contain the mechanism of regulation of actions of territorial communities, which experience difficulties when performing debt obligations. The article proves expediency of adoption of a uniform regulatory-legal act in Ukraine, which would regulate all economic relations connected with making municipal loans. This legal document shall contain a section about actions of the municipality-debtor when signs of default start to appear, announcement of default and declaration of the debtor insolvent (bankrupt. The article recommends the following structure of this section: regulation of the procedure of default announcement avoidance; announcement of default with the pre-trial restoration of the debtor’s solvency; and announcement of default with declaring the debtor bankrupt juridically.

    Full Text Available Soy occupies the largest area of agricultural land in Brazil, spreading from southern states to the Amazon region. Soy is also the most important agricultural commodity among Brazilian exports affecting food security and land use nationally and internationally. Here we pose the question of whether soy expansion affects only economic growth or whether it also boosts socioeconomic development, fostering education and health improvements in Brazilian municipalities where it is planted. To achieve this objective, we divided more than 5000 municipalities into two groups: those with >300 ha of soy (soy municipalities and those with <300 ha of soy (non-soy municipalities. We compared the Human Development Index (HDI and the Gini coefficient for income for these two groups of municipalities in 1991, 2000, and 2010. We made such comparison at the municipality level for the whole country, but we also grouped the municipalities by major geographical regions and states. We found that the HDI was higher in soy municipalities, especially in the agricultural frontier. That effect was not so clear in more consolidated agricultural regions of the country. Soy municipalities also had a higher Gini coefficient for income than non-soy municipalities. We concluded that soy could be considered a precursor of socioeconomic development under certain conditions; however, it also tends to be associated with an increase in income inequality, especially in the agricultural frontier.

  14. TOURISM AS A FACTOR OF MUNICIPAL DEVELOPMENT

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Tourism is one of the fastest growing industries in the world, which has extremely diverse impact on the lifestyle of the local population on the one hand and on the other for the modern traveler. At the same time, this modern "phenomenon" plays an important role in the socio-economic and political development of the host country, region or municipality, offering new employment opportunities for the local population and improving the way of life by providing additional income. The development of tourism in a municipality is based on a certain resource base, which consists of a variety of natural and anthropogenic resources, a prerequisite for the development of various alternative types of tourism. Its importance as a form of recreation consists mainly of its potential to be a leading factor in the development of municipalities and in diversifying their economic structure. Tourism has significant effects manifested by positive migratory balance, especially where the tourism industry is leading and is a driver of positive development. For the successful realization of tourism as a leading economic and social factor, it is important to make a real and precise system for its planning and management, adequate human resources competence as well as close cooperation between the public and private sector, legal tourist base, development and the implementation of tourism projects and last but not least, a real development strategy in the relevant municipality.

  15. Requirements for, and benefits of, environmentally sound and economically viable management of battery recycling in the Philippines in the wake of Basel Convention trade restrictions

    Science.gov (United States)

    Hoffmann, U.; Wilson, B.

    The ban on the export of used lead-acid batteries (ULAB) from Annex VII to non-Annex VII countries pursuant to decision III/1 of the Basel Convention reduced the availability of imported scrap feedstock for battery recycling in the Philippines. As ULAB supply from other developing countries becomes scarcer, the ban is likely to encourage and enhance collection and recuperation for domestically generated scrap. From a short-term perspective, this study explores the technological and managerial opportunities for improving the environmental and occupational health performance of the formal battery recycling sector and unregulated reconditioning. From a medium- and long-term point of view, the study investigates restructuring the informal ULAB's collection and recycling sector. The objective has been to make the smaller battery recyclers and reconditioners in the informal sector part of an effective and efficient collection infrastructure that supports an environmentally sound secondary lead sector. This approach gradually phases out uncontrolled, inefficient and environmentally unacceptable methods of secondary lead recovery. Due attention has also been paid to the logistical peculiarities of an archipelago, in particular the regional spread of collection infrastructure, collection and shipment costs as well as the assurance of environmentally safe transport.

  19. Energy utilization: municipal waste incineration. Final report

    Energy Technology Data Exchange (ETDEWEB)

    LaBeck, M.F.

    1981-03-27

    An assessment is made of the technical and economical feasibility of converting municipal waste into useful and useable energy. The concept presented involves retrofitting an existing municipal incinerator with the systems and equipment necessary to produce process steam and electric power. The concept is economically attractive since the cost of necessary waste heat recovery equipment is usually a comparatively small percentage of the cost of the original incinerator installation. Technical data obtained from presently operating incinerators designed specifically for generating energy, documents the technical feasibility and stipulates certain design constraints. The investigation includes a cost summary; description of process and facilities; conceptual design; economic analysis; derivation of costs; itemized estimated costs; design and construction schedule; and some drawings.

  3. Canadian municipal carbon trading primer

    Seskus, A.

    2002-01-01

    The trading of greenhouse gas (GHG) emissions is being suggested as an effective economic way to meet Canada's Kyoto target. Emissions trading is a market-based instrument that can help achieve environmental improvements while using the market to absorb the economical and effective measures to achieve emissions reductions. Placing a value on emissions means that in order to minimize costs, companies will be motivated to apply the lowest-cost emission reductions possible for regulatory approval. The two main types of emissions trading that exist in Canada are the trading of emissions that lead to the formation of smog or acid rain, and the trading of greenhouse gas emissions that lead to climate change. Since carbon dioxide is the most prevalent GHG, making up approximately 75 per cent of Canadian GHG emissions, the trading of units of GHGs is often referred to as carbon trading. The impact that emissions trading will have on municipal operations was the focus of this primer. The trading of GHG involves buying and selling of allowances of GHGs between contracting parties, usually between one party that is short of GHG credits and another that has excess credits. The 3 common approaches to emissions trading include allowance trading (cap and trade), credit trading (baseline and credit), and a hybrid system which combines both credit and allowance trading systems. The issues that impact municipalities include the debate regarding who owns the credits from landfills, particularly if power is generated using landfill gas and the power is sold as green power. Other viable questions were also addressed, including who can claim emission reduction credits if a city implements energy efficiency projects, or fuel substitution programs. Also, will municipalities be allowed to trade internationally, for example, with municipalities in the United States, and how should they spend their money earned from selling credits. This report also presents highlights from 3 emissions

    Austin, R.

    2006-01-01

    'Full text:' This paper explores the Municipal perspective of the Port Hope Area Initiative (PHAI). The PHAI is unique in that it emerged from proposals to the Federal Government and subsequently a tri-partite agreement between the Federal Government and the Municipalities of Port Hope and Clarington for the cleanup and management of historic low-level radioactive wastes in long-term waste management facilities in their Municipalities. A key feature of the Port Hope Project is the remediation of many major and small scale sites in the urban area. As part of this Legal Agreement, each Municipality is required to give consent at key milestones for the project to proceed to the next stage. In addition, the Municipality also has veto authority if the preferred option is changed by the federal government during its final review. The Agreement also ensures that the Municipalities have the resources to conduct an independent assessment of the work completed by the federal proponent and to advise the Municipality on related matters. While this Legal Agreement provides the Municipalities with influence over the outcome of the EA and the project description, especially when compared with the typical role of municipalities in other Federal EAs, there are many challenges that Port Hope faces as partner in this process. These include: Balancing Port Hope's interests with those of the Federal Government; Reaching agreement on how clean the remediation sites should be; Considering the interests of future generations while meeting the needs of existing residents; Ensuring that the Project will have a positive legacy for Port Hope; Ensuring that institutional controls are in place and that Port Hope has a partnership role in monitoring the Project performance during the Construction Phase and the long term Maintenance and Monitoring Phase. In this context, this paper presents the unique aspects of the Municipal involvement in the process to finally achieve a safe, environmentally

    Full Text Available The data of annual per capita income estimated by the United Nations Development Programme (UNDP for the municipal human development index in Mexico shows that, in Chiapas, during the period 2000-2005, there was a strong convergence at the municipal level while there was no regional convergence. To explain this apparent inconsistency, the article «Regression towards mediocrity in hereditary stature», published by Galton in 1886, is examined, concluding that the clustering level of the data (municipal or regional determines the convergence analysis results, because the grouping of municipalities in regions causes loss of information that can generate phenomena of «regression towards the mean» or just the opposite, as is the case. In Chiapas, the municipal convergence would have led to convergence within the regions but not between regions.A partir de los datos de ingreso per cápita anual estimados por el Programa de las Naciones Unidas para el Desarrollo (PNUD en la elaboración del índice de desarrollo humano municipal en México, se comprueba que, en el interior de Chiapas durante el periodo 2000- 2005, se dio un proceso de fuerte convergencia a nivel municipal al tiempo que no hubo convergencia regional. Para explicar esta aparente inconsistencia, se reexamina el artículo «Regression towards mediocrity in hereditary stature» publicado por Galton en 1886, concluyendo que el nivel de agrupación de los datos (municipal o regional condiciona los resultados del análisis de convergencia, ya que la agrupación de los municipios en regiones origina pérdidas de información que pueden generar fenómenos de «regresión hacia la media» o justo lo contrario, como es el caso.

  12. Determinants of municipal solid waste management in Portugal

    Directory of Open Access Journals (Sweden)

    Ana Luísa Mota Freitas

    2016-07-01

    Full Text Available Municipal solid waste management has been a topic of interest of several authors over time, in particular the implementation and maintenance of waste collection programmes. Initially, pioneering studies focused on the economic aspects of the provided services. However, many authors later argued the costs of providing solid waste collection services should also be influenced by socio-economic and behavioural factors, exogenous to the municipalities. The present study will be developed in this context, looking, more broadly, to explain the factors influencing the decision-making of the Portuguese municipalities in implementing and maintaining programs of selective collection of solid waste, considering the economic, financial, technological and sociodemographic factors. The results show that, indeed as presented by several authors before, economic factors aren’t the only determinants that influence municipal costs concerning these services, as demographic, geographic and technological factors must be taken into account. Moreover, the enforced legislation also impacts the municipal costs due to municipalities being obliged to contribute to the success of these collection programs in order to fulfil the waste recovery targets. This implies that the costs of these services and the inherent infrastructures are usually financed by its citizens in the form of utilization taxes and also the state.

    On 1 and 2 July, municipal energy managers from all over Europe met in Stuttgart, Germany. On these two days, more the 150 participants form 22 countries listened to presentations, took part in excursions to cutting-edge energy conservation projects in Stuttgart and, above all, participated in a broad array of workshops presented by experts firmly grounded in local practice. 27 experts drawn from 11 European countries showcased their projects and imparted their experience. The event has been accompanied by an exhibition of companies and service providers offering energy-conservation products and planning services. The first workshop dealt with energy management in Europe and examples from different active municipalities; the second one with energy management in Germany and best practice in the leading cities; the third one with non-municipal and European projects.

    Primer is a very low budget science-fiction film that deals with the subject of time travel; however, it looks and sounds quite distinctively different from other films associated with the genre. While Hollywood blockbuster sci-fi relies on “sound spectacle” as a key attraction, in contrast Primer sounds “lo-fi” and screen-centred, mixed to two channel stereo rather than the now industry-standard 5.1 surround sound. Although this is partly a consequence of the economics of its production, the...

  20. Types, risks and market of municipal bonds

    Directory of Open Access Journals (Sweden)

    Grujić Miloš

    2012-01-01

    Full Text Available Municipal bonds are issued by cities, municipalities or other local communities in order to quickly raise funds to cover current budget deficits, finish infrastructure projects for production and distribution of thermal energy, improve water supply, road construction, sports and recreation centers, schools or to fund such projects on more favorable terms than to borrow from banks. In this manner, necessary conditions are created for faster development of the real sector. The aim of this study is to evaluate the importance, possibilities and effects of the bond issue in the Republika Srpska aimed at securing funding for and development of local communities. Good examples that local government bonds enhance community development include capital markets in countries that have made the transition from the socialist system design, similar to the market of the Republika Srpska, like the Polish, Slovakian, Hungarian and Croatian markets. Issues of municipal bonds in the Republika Srpska succeeded mostly due to the workings of Investment-Development Bank of RS. However, it certainly shows that further high-quality municipal bonds could attract more interest from various institutional investors, especially mutual funds and insurance companies, and investors who are more risk-averse will be able to familiarize and inform themselves with the functioning of capital markets. In this manner, our capital market would confirm its essential role and thus become a generator of overall economic development of the Republika Srpska because it would enable more efficient collection and allocation of capital resources.

    This article examines the role that sound plays in making fictions perceptually real to film audiences, whether these fictions are realist or non-realist in content and narrative form. I will argue that some aspects of film sound practices and the kind of experiences they trigger are related...... to basic rules of human perception, whereas others are more properly explained in relation to how aesthetic devices, including sound, are used to characterise the fiction and thereby make it perceptually real to its audience. Finally, I will argue that not all genres can be defined by a simple taxonomy...... of sounds. Apart from an account of the kinds of sounds that typically appear in a specific genre, a genre analysis of sound may also benefit from a functionalist approach that focuses on how sounds can make both realist and non-realist aspects of genres sound real to audiences....

    2015-06-01

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

    Yamada, Izumi; Matsui, Yuji.

    1995-01-01

    Only components synchronized with rotation of pumps are sampled from detected acoustic sounds, to judge the presence or absence of abnormality based on the magnitude of the synchronized components. A synchronized component sampling means can remove resonance sounds and other acoustic sounds generated at a synchronously with the rotation based on the knowledge that generated acoustic components in a normal state are a sort of resonance sounds and are not precisely synchronized with the number of rotation. On the other hand, abnormal sounds of a rotating body are often caused by compulsory force accompanying the rotation as a generation source, and the abnormal sounds can be detected by extracting only the rotation-synchronized components. Since components of normal acoustic sounds generated at present are discriminated from the detected sounds, reduction of the abnormal sounds due to a signal processing can be avoided and, as a result, abnormal sound detection sensitivity can be improved. Further, since it is adapted to discriminate the occurrence of the abnormal sound from the actually detected sounds, the other frequency components which are forecast but not generated actually are not removed, so that it is further effective for the improvement of detection sensitivity.

  14. The effects of Smoke Free Work Hours in Danish municipalities

    Directory of Open Access Journals (Sweden)

    Tina Termansen

    2017-05-01

    Full Text Available Since 2011, 15 Danish municipalities have implemented smoke free work hours, meaning that an employee working for the municipality may not smoke in his or her work time (about 7,5 hours a day. This is a much stricter prevention method, than former strategies preventing smoking mostly at locations and not during working hours. Research concerning the effects of smoke free work hours is non-existing. We therefore wish to look into the specific outcomes of smoke free work hours related to smoking prevalence, sickness leave and work place culture through a semi-experimental study. As the decision to implement smoke free work hours is administrative and/or political, we will not be able to randomize the intervention. Instead, we use one or more Danish municipality who are planning to implement smoke free work hours as an intervention-group and similar municipalities as control group. Data will be collected both through questionnaires about employees smoking prevalence, sickness leave and work place community, and through register data about the citizens employed in the municipalities in question. This will primarily be data on socio-economic status and health. In this way we can compare the municipalities implementing smoke free work hours with each other and find similar control municipalities. We hope, that this study can contribute to understanding the specific outcomes of implementing smoke free work hours, focusing both on health outcomes and work place culture.

    International Nuclear Information System (INIS)

    2004-01-01

    The establishment of the Municipality of Sopishte was preceded by the development of a kind of suburban settlement of Skopje, basically composed of illegally constructed individual houses for living. As a result from economic activities in the Municipality and the impacts from human factor, there are problems related to the disturbance of the quality of the basic environmental quality factors (water, air and soil), as well as threat to biological diversity and natural values and rarities. The Municipality of Sopishte is situated in hilly-mountain area. Significant sources of air pollution have not been recorded (in terms of industrial facilities) caused by the household neglectible air pollution caused by traffic. The Municipality is very poor in water resources. Almost 90% of the Municipality's territory are without river or stream. A potential source of water supply in this area is the river of Patishka, which is currently not used for water supply purposes. The solid waste, generated basically by the households, is not properly disposed (most frequently dumped on illegal dumping sites on the territory of the Municipality) and represents a serious problem making impacts on the quality of the environment. On the basis of the evaluation of identified environmental problems, priority activities required to be undertaken in short and medium term have been set up. Financial constrains have been taken into account in this regard. The proposed Action Plan reflects the observed needs of the population of the Municipality of Sopishte and the perception of the key problems

    2015-12-01

    Full Text Available Centralization of municipal procurement in the KwaZulu-Natal Province is faced with several challenges. There were two aims for this study: to identify factors influencing municipal procurement and to design a model of the factors influencing municipal procurement, in an attempt to improve the understanding of municipal procurement. The proposed model is based on sound theoretical frameworks like knowledge management theory and the application of theory and practice ethics as well as the secondary data. The study found that the biographic factors as well as internal and external factors have strong influences on the success or failure of municipal procurement. The significance of these factors formed the basis for a proposed model and is subject to further experiments by other scholars.

    Sound is integral to how we experience the world, in the form of noise as well as music. But what is sound? What is the physical basis of pitch and harmony? And how are sound waves exploited in musical instruments? Sound: A Very Short Introduction looks at the science of sound and the behaviour of sound waves with their different frequencies. It also explores sound in different contexts, covering the audible and inaudible, sound underground and underwater, acoustic and electronic sound, and hearing in humans and animals.

    2016-07-01

    Full Text Available In order to promote sustainable socio-economic development in a municipality, its local authorities face the task of establishing an industrial and financial base on their territory, it will help increase its level of economic independence. On the basis of foreign experience and domestic research on territorial development it can be concluded that one of the most effective ways to enhance the level of socio-economic development of the municipality is to boost its small business. Effective management of this economic sector requires adequate assessment of its functioning at the municipal level. The analysis of existing methodologies for assessing the functioning of small business at the municipal level shows that none of them meets the criteria that the author of the present paper has selected and that are necessary for efficient research into the small business sector. In this regard, a methodology for estimating the work of small business at the municipal level was elaborated, and tested on the statistic data of municipal formations of the Vologda Oblast. The study reveals municipalities with the highest and lowest levels of small business development. In addition, municipalities were grouped in three blocks that represent different characteristics of their functioning. Taking into account the problems of business subjects, the study has developed measures to increase the level of development for each group of municipalities. Implementing these activities will help intensify the work of the sector of the economy under consideration, and increase the economic independence of territorial formations in the region. The paper can be used to assess the effectiveness of activities aimed to support small business in the region and to help regional and municipal authorities to work out a strategy for further development of this economic sector

In this study, we investigated the influence of vowels on sound–shape matching in toddlers, using four contrasting pairs of nonsense words differing in vowel sound (/i/ as in feet vs. /o/ as in boat and four rounded–jagged shape pairs. Crucially, we used reduplicated syllables (e.g., kiki vs. koko rather than confounding vowel sound with consonant context and syllable variability (e.g., kiki vs. bouba. Toddlers consistently matched words with /o/ to rounded shapes and words with /i/ to jagged shapes (p < 0.01. The results suggest that there may be naturally biased correspondences between vowel sound and shape.

    Waste management planning requires reliable data concerning waste generation, influencing factors on waste generation and forecasts of waste quantities based on facts. This paper aims at identifying and quantifying differences between different municipalities' municipal solid waste (MSW) collection quantities based on data from waste management and on socio-economic indicators. A large set of 116 indicators from 542 municipalities in the Province of Styria was investigated. The resulting regression model included municipal tax revenue per capita, household size and the percentage of buildings with solid fuel heating systems. The model explains 74.3% of the MSW variation and the model assumptions are met. Other factors such as tourism, home composting or age distribution of the population did not significantly improve the model. According to the model, 21% of MSW collected in Styria was commercial waste and 18% of the generated MSW was burned in domestic heating systems. While the percentage of commercial waste is consistent with literature data, practically no literature data are available for the quantity of MSW burned, which seems to be overestimated by the model. The resulting regression model was used as basis for a waste prognosis model (Beigl and Lebersorger, in preparation). Copyright © 2011 Elsevier Ltd. All rights reserved.

    The efficient handling of the economic and natural resources of the municipalities, is nowadays so much complex, that it requires a formal planning. In the public service of potable water supply, two fundamental approaches are conjugated to consider: the rational use of the water resource and the efficient use of the electrical energy, for its extraction from the underground deep reservoirs. In the paper that is presented, the individual features of the previous matters are described and the positive results in a municipality of the Guanajuato's Low Lands (Bajio ), where already the dual objectives are obtained and that with a more professional municipal hydraulic planning, these will be permanent, with the inherent benefit towards the population. [Spanish] El manejo eficiente de los recursos economicos y naturales de los municipios, es hoy en dia cada vez mas complejo, que requiere una planeacion formal. En el servicio publico de abastecimiento de agua potable, se conjugan dos enfoques primordiales a considerar: el uso racional del recurso agua y la utilizacion eficiente de la energia electrica, para su extraccion de los acuiferos subterraneos profundos. En el trabajo que se presenta, se describen las particularidades de lo anterior y los resultados positivos en un municipio del Bajio guanajuatense, donde ya se logran los objetivos duales y que con una planeacion hidraulica municipal mas profesional, estos seran permanentes, con el beneficio inherente hacia la poblacion.

  7. Waveform analysis of sound

    CERN Document Server

    Tohyama, Mikio

    2015-01-01

    What is this sound? What does that sound indicate? These are two questions frequently heard in daily conversation. Sound results from the vibrations of elastic media and in daily life provides informative signals of events happening in the surrounding environment. In interpreting auditory sensations, the human ear seems particularly good at extracting the signal signatures from sound waves. Although exploring auditory processing schemes may be beyond our capabilities, source signature analysis is a very attractive area in which signal-processing schemes can be developed using mathematical expressions. This book is inspired by such processing schemes and is oriented to signature analysis of waveforms. Most of the examples in the book are taken from data of sound and vibrations; however, the methods and theories are mostly formulated using mathematical expressions rather than by acoustical interpretation. This book might therefore be attractive and informative for scientists, engineers, researchers, and graduat...

    Computing practice today depends on visual output to drive almost all user interaction. Other senses, such as audition, may be totally neglected, or used tangentially, or used in highly restricted specialized ways. We have excellent audio rendering through D-A conversion, but we lack rich general facilities for modeling and manipulating sound comparable in quality and flexibility to graphics. We need coordinated research in several disciplines to improve the use of sound as an interactive information channel. Incremental and separate improvements in synthesis, analysis, speech processing, audiology, acoustics, music, etc. will not alone produce the radical progress that we seek in sonic practice. We also need to create a new central topic of study in digital audio research. The new topic will assimilate the contributions of different disciplines on a common foundation. The key central concept that we lack is sound as a general-purpose information channel. We must investigate the structure of this information channel, which is driven by the cooperative development of auditory perception and physical sound production. Particular audible encodings, such as speech and music, illuminate sonic information by example, but they are no more sufficient for a characterization than typography is sufficient for characterization of visual information. To develop this new conceptual topic of sonic information structure, we need to integrate insights from a number of different disciplines that deal with sound. In particular, we need to coordinate central and foundational studies of the representational models of sound with specific applications that illuminate the good and bad qualities of these models. Each natural or artificial process that generates informative sound, and each perceptual mechanism that derives information from sound, will teach us something about the right structure to attribute to the sound itself. The new Sound topic will combine the work of computer

  11. Potential use of feebate systems to foster environmentally sound urban waste management

    International Nuclear Information System (INIS)

    Puig-Ventosa, Ignasi

    2004-01-01

    Waste treatment facilities are often shared among different municipalities as a means of managing wastes more efficiently. Usually, management costs are assigned to each municipality depending on the size of the population or total amount of waste produced, regardless of important environmental aspects such as per capita waste generation or achievements in composting or recycling. This paper presents a feebate (fee+rebate) system aimed to foster urban waste reduction and recovery. The proposal suggests that municipalities achieving better results in their waste management performance (from an ecological viewpoint) be recompensated with a rebate obtained from a fee charged to those municipalities that are less environmentally sound. This is a dynamic and flexible instrument that would positively encourage municipalities to reduce waste whilst increasing the recycling

  20. The impact of municipal budgets and land-use management on the hazardous waste production of Malaga municipalities

    International Nuclear Information System (INIS)

    Soler, Ismael P.; Gemar, German; Jimenez-Madrid, Alberto

    2017-01-01

    Economic development and the search for competitiveness have become key issues in regions' economic success. However, despite the direct relationship between economic and environmental management, few land-use plans consider the latter aspect, and city managers delegate the responsibility for environmental impacts to state legislation and private initiatives. This myopic search for competitiveness has meant that a holistic view of environmental issues is often not integrated into municipal decision-making processes. Therefore, this study's objective was to determine the relevant direct and indirect relationships of land management and budgetary procedures of municipalities with overall production levels of hazardous waste. To this end, a primary tourist region, Málaga, was examined in terms of how this waste's environmental impacts can affect the region's vital tourism sector. This research used principal component analysis, regression by ordinary least squares, cluster analysis in two stages and a means test to compare the data for the Province of Malaga's subregions. The results confirm a positive relationship between municipal expenditure and waste production and highlight the environmental benefits of land use involving environmentally non-aggressive crops. The results also reveal a negative relationship between waste production and financial assets and a direct relationship between unproductive land and the production of hazardous waste. The findings also highlight the necessity of raising awareness about the need for collaboration between different agents, especially in the development of inter-municipal strategies.

    The existence of different classifications of municipal solid waste (MSW) creates confusion and makes it difficult to interpret and compare the results of generation analyses. In this paper, MSW is conceptualized as the solid waste generated within the territorial limits of a municipality, independently of its source of generation. Grounded on this assumption, and based on the economic activity that generates a solid waste with determinate physical and chemical characteristics, a hierarchical source classification of MSW is suggested. Thus, a connection between the source and the type of waste is established. The classification categorizes the sources into three divisions and seven classes of sources: residential, commercial, institutional, construction/demolition, agricultural-animal husbandry, industrial, and special. When applied at different geographical scales, this classification enables the assessment of the volume of MSW generated, and provides an overview of the types of residues expected to be generated in a municipality, region or state.

    The nuclear policies of the most important countries in Western Europe, already influenced by the evolution of the public opinion, have experimented strong changes together with political evolution. The future of NNP in some important countries is doubtful, as for the case of Sweden, Germany, Spain, Holland, Belgium, The large democratic discussions that affect permanently our society, as well as the new society of information that is being implanted, have turned the decision making processes into what is referred to as public participation and transparency, especially when these affect the environment or the immediate future of the citizens. The installation policies of nuclear plants are very similar in all the countries. Most of them are located in low density population areas, with low activity rate, high rate of elder people. These territories have many water resources, low communication infrastructure level, etc. So the typographic aspects of the European municipalities are alike (in eastern countries as well). Nuclear energy whose existence is sometimes called in question by press media, citizens and inhabitants, needs full agreement within the territory in order to work at its best. Moreover, the territory on which the plant is installed must have the necessary means of infrastructure ( development from a social and economic point of view) as well as the dues for its future and for a new positive reality as far as the citizens are concerned in order to face the corresponding challenges. Having got to this point, a territorial debate should be focused on the balance between the state's general interest and the local one as normalised operation of nuclear facilities is and will be possible only in a context of mutual respect. The new European political map and the last governmental decisions in energetic strategies grant more value to the opinion of the local authorities on the territories affected by these facilities.

    Full Text Available This paper presents the results of research on the application of neural networks modelling of municipal real estate market rent rates. The test procedure was based on selected networks trained on the local real estate market data and transformation of the detected dependencies – through established models – to estimate the potential market rent rates of municipal premises. On this basis, the assessment of the adequacy of the actual market rent rates of municipal properties was made. Empirical research was conducted on the local real estate market of the city of Olsztyn in Poland. In order to describe the phenomenon of market rent rates formation an unidirectional three-layer network and a network of radial base was selected. Analyses showed a relatively low degree of convergence of the actual municipal rent rents with potential market rent rates. This degree was strongly varied depending on the type of business ran on the property and its’ social and economic impact. The applied research methodology and the obtained results can be used in order to rationalize municipal property management, including the activation of rental policy.

    Large urban centers have a huge demand for electricity, for the needs of its residents, and a growing problem of management of solid waste generated by it, that becomes an public administrative and great social problem. The correct disposal of solid waste generated by large urban centers is now one of the most complex engineering problems involving logistics, safety, environment, energy spent among other tools for sound management of municipal solid waste (MSW). This study was carried out a study of the use of incinerators and residue derived fuel and MSW with combined cycles, with the aim of producing thermal and mechanical energy (this later becomes electrical energy) and solid waste treatment in Sao Paulo. We used existing models and real plants in the European Union in this case, with the aim of making it the most viable and compatible with the current context of energy planning and resource today. A technical and economic feasibility study for a plant of this nature, using the scheme, is presented. It is expected a good attractiveness of using incinerators combined-cycle, due to its high efficiency and its ability to thermoelectric generation. (author)

    Full Text Available Background: Due to the lack of a proper waste management system, Tehran Municipality Region 20 is facing economic and environmental problems such as the high costs of a disposal system and source pollution. Life cycle assessment (LCA is a method for collecting and evaluating the inputs, outputs, and potential environmental impacts of a product system throughout its life cycle. The current study purposed to provide a stable and optimized system of solid waste management in Tehran Municipality Region 20. Methods: The LCA method was used to evaluate various scenarios and compare the effects on environmental aspects of management systems. Four scenarios were defined based on existing and possible future waste management systems for this region. These scenarios were considered with different percentages for source separation, composting, recycling, and energy recovery. Results: Based on the results of this study, Scenario 4 (source separation [14%] + composting [30%] + municipal recycling facility [MRF] [20%] + energy recovery [10%] + landfilling [26%] was found to be the option with the minimum environmental impact. In the absence of government support and sufficient funds for establishing energy recovery facilities, the third scenario (source separation [14%] + composting [30%] +MRF [20%] + landfilling [36%] is recommended. Conclusion: The results acquired from this investigation will confirm the belief that LCA as an environmental device may be successfully used in an integrated solid waste management system (ISWMS as a support tool for decision-making.

    The Mississippi Sound Remote Sensing Study was initiated as part of the research program of the NASA Earth Resources Laboratory. The objective of this study is development of remote sensing techniques to study near-shore marine waters. Included within this general objective are the following: (1) evaluate existing techniques and instruments used for remote measurement of parameters of interest within these waters; (2) develop methods for interpretation of state-of-the-art remote sensing data which are most meaningful to an understanding of processes taking place within near-shore waters; (3) define hardware development requirements and/or system specifications; (4) develop a system combining data from remote and surface measurements which will most efficiently assess conditions in near-shore waters; (5) conduct projects in coordination with appropriate operating agencies to demonstrate applicability of this research to environmental and economic problems.

  12. Tourist valorization of the municipality of Negotin

    2010-01-01

    Full Text Available According to its physical-geographical and socio-economical characteristics, the municipality of Negotin belongs to the territories with favorable tourist potentials. In order to scientifically validate this fact, in this paper tourist valorization has been performed using quantitative-qualitative method, giving attractiveness ranking values, based on which conclusions have been made on the direction and forms of tourist potential. The results obtained from tourist valorization have shown that the hydrographic potential and fauna are rated as good (3, and have the highest general tourist value among natural resources. General values are graded as satisfactory (1.8 and the climate is graded as unsatisfactory (1.2. Valorization of anthropogenic characteristics gave the maximal general value (4 to cultural-historical objects including sacral objects - monasteries and churches and the Rajac pimnice. The Rajac pimnice have an especially high value, as they represent, for us, a unique value that can be considered in diverse ways and adjusted to tourist utilization. Based on the performed tourist valorization it can be noted that the general tourist value of the municipality of Negotin is of regional ranking, though anthropogenic potentials are of national ranking and part of them, as emphasized, are objects that are internationally important. The basic shortcoming is the low road quality leading to places of important tourist value, even though the road network is favorable, and there are also many weaknesses in the receptive tourist base. Improvement of these shortcomings would create a good image of the municipality of Negotin in continental tourism of the Republic of Serbia.

  13. Do Municipal Governments Need More Tax Powers? A Background Paper on Municipal Finance in Alberta

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available Local governments in Alberta have faced considerable and variable challenges over the past 60 years. For example, the rapid population and economic growth during the 1950s, ’60s and ’70s created exceptional demands for schools, schooling and municipal infrastructure; demands exceeding those of the last 30 years. Local and especially municipal financing has relied heavily on the property tax throughout. Questions are being asked today about whether the property tax is sufficient for municipal government. Our historical analysis provides insights into the fiscal situation of Alberta’s municipalities that can assist in addressing those questions. The main findings are highlighted here. We conclude that current demands, though considerable, are not creating stress on the property tax as a source of municipal revenue. • The property tax burden in Alberta during the past decade is the lowest that it has been over the past 60 years. Presently, property taxes are about 3.5 per cent of personal income. They were as high as seven per cent during much of the 1960s and averaged in the four to five per cent range from 1950 to 2000. Local and provincial school taxes were responsible for most of the fluctuations in the property tax burden. Municipal property taxes ranged from two to three per cent of personal incomes and recently amounted to about 2.5 per cent, a level typical of that over the past 20 years. • Investment in local infrastructure has over the past 30 years been at half the rate of that of the previous 30 years. Only since 2006, with the assistance of provincial capital grants, has infrastructure spending shown upward movement. Capital spending lagged population growth for many years and probably contributed to a deterioration of infrastructure. • Municipal current or operating expenditures (about three-quarters of the total have been a declining share of personal incomes since the late 1980s and, since 2000, are a smaller share than

    Sensory experiences are often considered triggers of memory, most famously a little French cake dipped in lime blossom tea. Sense memory can also be evoked in public history research through techniques of elicitation. In this article I reflect on different social science methods for eliciting sound memories such as the use of sonic prompts, emplaced interviewing, and sound walks. I include examples from my research on medical listening. The article considers the relevance of this work for the conduct of oral histories, arguing that such methods "break the frame," allowing room for collaborative research connections and insights into the otherwise unarticulatable.

    2005-01-01

    District heating (DH) and cogeneration of heat power (CHP) are well known technologies in the energy business and are often included in municipal policies as well. Some of the major benefits of DH and CHP are less known and the barriers faced by further development of DH and CHP are substantial. The main barriers are institutional. Municipalities can play a powerful role in facilitating local DH and CHP development in order to achieve the economic and environmental benefits of DH and CHP. This report is produced to assist municipalities in promoting efficient and environmental beneficial DH and CHP. The focus of the report is on the economies in transition, where the institutional barriers are acute. The report addresses the issues of organisational framework, price regulation and financing, energy demand, rehabilitation of DH systems and benchmarking of DH and CHP. The municipality may influence the DH development by a number of means. The most important means, discussed in the various chapters of the report, are: (1) City planning impacts on the heat load density. A high density is an important factor for the economics of DH and city planning may promote DH in areas with high density and individual heating modes in the areas with low density; (2) Managing the building stock owned by the municipality to join the DH system and paying for the heating services; (3) Setting strategic goals for the District Heating Enterprise (DHE), which they usually own, regarding the quality and the costs of heating. The DHE shall be given sufficient resources to work towards such goals; (4) Providing guarantees for financing DH rehabilitation and development. The DHE may not have access to commercial credits without municipal guarantees; and, (5) Supporting the DHE management by giving operational independence, supervising the management performance regularly and encouraging the co-operation with other DHEs and equipment manufacturers.

    Full Text Available The relationship between meanings of words and their sound shapes is to a large extent arbitrary, but it is well known that languages exhibit sound symbolism effects violating arbitrariness. Evidence for sound symbolism is typically anecdotal, however. Here we present a systematic approach. Using a selection of basic vocabulary in nearly one half of the world’s languages we find commonalities among sound shapes for words referring to same concepts. These are interpreted as due to sound symbolism. Studying the effects of sound symbolism cross-linguistically is of key importance for the understanding of language evolution.

    It is common that a physical system resonates at a particular frequency, whose frequency depends on physical parameters which may change in time. Often, one would like to automatically track this signal as the frequency changes, measuring, for example, its amplitude. In scientific research, one would also like to utilize the standard methods, such as lock-in amplifiers, to improve the signal to noise ratio. We present a complete He ii second sound system that uses positive feedback to generate a sinusoidal signal of constant amplitude via automatic gain control. This signal is used to produce temperature/entropy waves (second sound) in superfluid helium-4 (He ii). A lock-in amplifier limits the oscillation to a desirable frequency and demodulates the received sound signal. Using this tracking system, a second sound signal probed turbulent decay in He ii. We present results showing that the tracking system is more reliable than those of a conventional fixed frequency method; there is less correlation with temperature (frequency) fluctuation when the tracking system is used.

    High-speed photometric observations of meteor fireballs have shown that they often produce high-amplitude light oscillations with frequency components in the kHz range, and in some cases exhibit strong millisecond flares. We built a light source with similar characteristics and illuminated various materials in the laboratory, generating audible sounds. Models suggest that light oscillations and pulses can radiatively heat dielectric materials, which in turn conductively heats the surrounding air on millisecond timescales. The sound waves can be heard if the illuminated material is sufficiently close to the observer’s ears. The mechanism described herein may explain many reports of meteors that appear to be audible while they are concurrently visible in the sky and too far away for sound to have propagated to the observer. This photoacoustic (PA) explanation provides an alternative to electrophonic (EP) sounds hypothesized to arise from electromagnetic coupling of plasma oscillation in the meteor wake to natural antennas in the vicinity of an observer.

    Full Text Available When the South African Government in 1998 re-demarcated its 283 municipalities so that they completely cover the country in a “wall-to-wall” manner, their main focus was on growing local economies and maintaining the provision of an increased number of diverse and more complex basic municipal services to new geographical areas consisting of millions of citizens who might previously had been neglected. In most of the instances the newly established and merged municipalities were demarcated according to geographical aspects inherited from the previous political dispensation, historical municipal areas and magisterial district farm names. The fact that these municipal government jurisdictions for the purpose of improving co-operative municipal- and integrated water resources management (IWRM, in most instances do not correspond with environmental and physical land features such as the demarcated surface water (rivers drainage regions’ boundaries, could lead to the ineffective, inefficient and non-economic municipal management of water, sanitation and environmental services. The aforementioned is a case with reference to water services management in the Free State Province town of Lindley located in the Vals River catchment and the Nketoana Local Municipality’s area of jurisdiction. An extensive literature review, the use and study of geographic tools such as maps, ortho- photos and information data bases, as well as two field visits to the area, enabled the researchers to identify the essential geographical, geo-hydrological and municipal management aspects of importance for the potable water service providers and managers in the Lindley municipal area. The researchers argue that effective trans-boundary municipal management through simunye-type co-operative governance and IWRM must be facilitated in the Vals River surface water catchment between the respective local- and district municipalities for the benefit of the Lindley, Arlington

  8. Teatro Municipal, en Gelsenkirchen

    Ruhnau, Werner

    1963-10-01

    Full Text Available Two very up to date principles have been tried at Gelsenkirchen, namely that of «transformable theatre», and the integration of the style of a building with that of the town and the landscape. Following these principles, two municipal theatres have been built, one seating 1,050 and the other 450 spectators. They are situated in the centre of the city, and constitute the nucleus of a new cultural centre in the midst of a highly industrial town; This is a project not aimed at any particular social group, but placed at the service of every man with an intellectual or artistic interest. These two buildings have reinforced concrete structures, metal roofs, and the trusses are protected against Are by means of a special asbestos treatment. Efficient air conditioning ducts are taken inside suspended concrete tubing, which run over the main theatre hall. This air conditioning produces no audible noise. The «transformability» of the theatre presented other difficult accoustical problems, which were overcome by means of plates which osciIate and open out. Aluminium laminas, with a large number of tiny holes to absorb noise, have also been fitted. These two buildings involve a close cooperation between the plastic artist and the architect. A number of works by Paul Dierkes and Yves Klein are placed inside these theatres. Externally. they are adorned with a concrete sculpture by Robert Adams, seeking to express the power of the spirit over matter.Dos principios muy de actualidad —de «teatro transformable» y de integración de la arquitectura en la ciudad y paisaje— han sido intentados en Gelsenkirchen, donde se construyeron dos teatros municipales: uno con 1.050 localidades y otro con 450. Emplazados en el centro de la ciudad, constituyen, como el núcleo de un nuevo foro, una obra al servicio del arte, del espíritu, en medio de una urbe industrial: una obra destinada no a una determinada clase social, sino para cada hombre interesado intelectual

    International Nuclear Information System (INIS)

    1991-03-01

    EPA believes that the most effective and equitable means of assuring viability of this infrastructure is through environmentally preferred pollution prevention approaches especially through application of Municipal Water Pollution Prevention (MWPP). These approaches may enhance worker safety, improve the usability of sludge, increase the ability for local community expansion, and reduce operation and compliance costs. State-based municipal pollution prevention programs focus attention on a series of actions to prevent pollution in advance rather than taking more expensive corrective actions. MWPP encourages resource conservation to reduce water and energy use, appropriate pricing, toxicity reductions at the source, BOD reductions, recycling, proper treatment of wastes, and beneficial uses of sludge

    2006-01-01

    The author explains how local politicians look upon the dialogue regarding nuclear installations in their municipalities. As seen from the map of European reactors there is a lot of local districts affected by nuclear operations. What has a mayor from such a community to say about the shut-down phase of such operations and especially about the need for communication between stakeholders when closing and decommissioning a nuclear power reactor? To answer this question the author has structured his presentation into 4 parts as follows: 1. The European municipalities ? some characteristics; 2. The siting of NPPs (nuclear power plants) in Europe; 3. The shutdown, decommissioning and the dismantling phases; 4. Lessons learnt

    2005-12-01

    Starting in the early 1960s, spacecraft-borne plasma wave instruments revealed that space is filled with an astonishing variety of radio and plasma wave sounds, which have come to be called "sounds of space." For over forty years these sounds have been collected and played to a wide variety of audiences, often as the result of press conferences or press releases involving various NASA projects for which the University of Iowa has provided plasma wave instruments. This activity has led to many interviews on local and national radio programs, and occasionally on programs haviang world-wide coverage, such as the BBC. As a result of this media coverage, we have been approached many times by composers requesting copies of our space sounds for use in their various projects, many of which involve electronic synthesis of music. One of these collaborations led to "Sun Rings," which is a musical event produced by the Kronos Quartet that has played to large audiences all over the world. With the availability of modern computer graphic techniques we have recently been attempting to integrate some of these sound of space into an educational audio/video web site that illustrates the scientific principles involved in the origin of space plasma waves. Typically I try to emphasize that a substantial gas pressure exists everywhere in space in the form of an ionized gas called a plasma, and that this plasma can lead to a wide variety of wave phenomenon. Examples of some of this audio/video material will be presented.

    2001-01-01

    This paper is focussed on how municipal elected leaders in three Swedish feasibility study municipalities - Nykoeping, Oskarshamn and Tierp - have tried to ensure that future decisions by their respective municipalities will be based both on factual knowledge and on existing opinions held by the general public. These efforts have contributed to an empowerment of the legitimacy of municipal decision-making within the nuclear waste management field and, probably, also served as a factor contributing to trust building with regard to these issues. The three cases show three ways to handle the problem, although there are also common features. The municipalities of Nykoeping and Oskarshamn have been facing these issues since 1995. In the case of Tierp, the municipality was confronted in late 1998 with the task to choose a strategy for its involvement in the site selection process and then, immediately, implement that strategy. A decision to construct a final repository for spent nuclear fuel has an obvious local dimension. It is not enough that an implementer is capable of developing a method that is considered to be safe enough by the regulatory authorities and by the Government. Nor is it enough that the implementer has succeeded to choose a site that these institutions consider to be suitable. A vital condition for a successful result is also that the general public, especially people living close to the site, have trust in the process leading up to the decision - and of course also that the general public is confident that the implementer and the regulator have agreed on a sound technical solution of the disposal problem. In other words, decisions in this area by Government and regulatory authorities do not only have to comply with existing legislation (obviously decisions by such bodies have to be 'legal'); they also should have a democratic legitimacy. In a representative democracy like Sweden, with high voting participation, it may seem self-evident that the

    Full Text Available Municipal infrastructure is a fundamental facility for the normal operation and development of an urban city and is of significance for the stable progress of sustainable urbanization around the world, especially in developing countries. Based on the municipal infrastructure data of the prefecture-level cities in China, municipal infrastructure development is assessed comprehensively using a FA (factor analysis model, and then the stochastic model STIRPAT (stochastic impacts by regression on population, affluence and technology is examined to investigate key factors that influence municipal infrastructure of cities in various stages of urbanization and economy. This study indicates that the municipal infrastructure development in urban China demonstrates typical characteristics of regional differentiation, in line with the economic development pattern. Municipal infrastructure development in cities is primarily influenced by income, industrialization and investment. For China and similar developing countries under transformation, national public investment remains the primary driving force of economy as well as the key influencing factor of municipal infrastructure. Contribution from urbanization and the relative consumption level, and the tertiary industry is still scanty, which is a crux issue for many developing countries under transformation. With economic growth and the transformation requirements, the influence of the conventional factors such as public investment and industrialization on municipal infrastructure development would be expected to decline, meanwhile, other factors like the consumption and tertiary industry driven model and the innovation society can become key contributors to municipal infrastructure sustainability.

    Highlights: • We have modelled household waste generation in Biscay municipalities. • We have identified relevant characteristics regarding household waste generation. • Factor models are used in order to identify the best subset of explicative variables. • Biscay’s municipalities are grouped by means of hierarchical clustering. - Abstract: The planning of waste management strategies needs tools to support decisions at all stages of the process. Accurate quantification of the waste to be generated is essential for both the daily management (short-term) and proper design of facilities (long-term). Designing without rigorous knowledge may have serious economic and environmental consequences. The present works aims at identifying relevant socio-economic features of municipalities regarding Household Waste (HW) generation by means of factor models. Factor models face two main drawbacks, data collection and identifying relevant explanatory variables within a heterogeneous group. Grouping similar characteristics observations within a group may favour the deduction of more robust models. The methodology followed has been tested with Biscay Province because it stands out for having very different municipalities ranging from very rural to urban ones. Two main models are developed, one for the overall province and a second one after clustering the municipalities. The results prove that relating municipalities with specific characteristics, improves the results in a very heterogeneous situation. The methodology has identified urban morphology, tourism activity, level of education and economic situation as the most influencing characteristics in HW generation.

    Though per capita waste generation in Nepalese urban cities is not so high, the lack of proper waste management is considered one of the severe problems to be faced by urban people in future. With rapid urbanization, life style of people is changing their habits and consuming more materials and producing a large volume of waste in urban areas in Nepal. The nature and amount of waste generated in municipality is dependent of demography and geography. But most common aspect of municipal waste in Nepal is more than 60% of the waste biodegradable. Whatever the nature and amount of waste generated, the most common practice of managing municipal waste is to dispose in the riverside nearby or dumped elsewhere. The involvement of private sector in waste management is a new concept adopted by many municipalities in Nepal. One of the most progress approaches, 4R (reduces, reuse, recycle and refuse) principle is being practiced. The need of awareness progressive like segregation of wastes at collection point also being practiced in Nepal. Finally, Proper formulation of program and legislation and its application is one of the major challenges for local authorities in Nepal. (author)

    2010-01-01

    Energy management systems are highly complicated with greenhouse-gas emission reduction issues and a variety of social, economic, political, environmental and technical factors. To address such complexities, municipal energy systems planning models are desired as they can take account of these factors and their interactions within municipal energy management systems. This research is to develop an interval-parameter two-stage stochastic municipal energy systems planning model (ITS-MEM) for supporting decisions of energy systems planning and GHG (greenhouse gases) emission management at a municipal level. ITS-MEM is then applied to a case study. The results indicated that the developed model was capable of supporting municipal energy systems planning and environmental management under uncertainty. Solutions of ITS-MEM would provide an effective linkage between the pre-regulated environmental policies (GHG-emission reduction targets) and the associated economic implications (GHG-emission credit trading).

    The unique mechanical and acoustical properties of wood and its aesthetic appeal still make it the material of choice for musical instruments and the interior of concert halls. Worldwide, several hundred wood species are available for making wind, string, or percussion instruments. Over generations, first by trial and error and more recently by scientific approach, the most appropriate species were found for each instrument and application. Using material property charts on which acoustic properties such as the speed of sound, the characteristic impedance, the sound radiation coefficient, and the loss coefficient are plotted against one another for woods. We analyze and explain why spruce is the preferred choice for soundboards, why tropical species are favored for xylophone bars and woodwind instruments, why violinists still prefer pernambuco over other species as a bow material, and why hornbeam and birch are used in piano actions.

    Full Text Available A strong underlying structure in the economic, demographic, and entrepreneurial domains of local authorities (municipalities in the Free State, South Africa was detected through cluster and other analyses. The structure is indicative of a system in which economic value addition, population size, employment creation, and entrepreneurial domains are dynamically linked. The agriculture, mining, and fuel and chemicals sectors dominate the economic value addition in some municipalities, whereas others are without a single dominating economic sector (i.e. they have well-balanced economies. The agriculture and households sectors are significant sources of employment in all municipalities. Cluster sequence analyses of the municipalities revealed statistically significant recurring patterns of value addition, employment, and entrepreneurship, further strengthening the detection of orderliness, which can promote mutual learning. The Metsimaholo municipality with a significant manufacturing base is an atypical Free State municipality and provides an outstanding example of the economic, demographic, and entrepreneurial impacts of value addition to local or external primary products.

    To analyse the ecological association between the demographic and socio-economic characteristics of the Brazilian municipalities and average leprosy incidence rate in the period 2009-2011. An ecological study taking the Brazilian municipalities as its units of analysis. The local empirical Bayes estimation method was used to obtain smoothed incidence rates (SIR) for leprosy. The mean, median, first quartile (Q1) and third quartile (Q3) of the SIR were calculated per 100 000 inhabitants. Hierarchical log-linear negative binomial regression models were used to estimate the incidence rate ratios (IRR). In the period 2009-2011, the average SIR of leprosy in Brazil was 20.2 per 100 000 inhabitants, and the median incidence rate among municipalities was 9.1 per 100 000 inhabitants. Significantly higher adjusted IRR were identified for large municipalities (IRR = 1.67) compared to small municipalities, as well as in municipalities with higher illiteracy rates (IRR = 2.15), more urbanised municipalities (IRR = 1.53), those with greater social inequality as per the Gini index (IRR = 1.26), high percentage of households with inadequate sanitation (IRR = 1.63), higher average number of people per room (IRR = 1.41), high proportions of Family Health Programme coverage (IRR = 1.29), high percentage of household contacts investigated (IRR = 2.30) and those with percentage of cases with grade 2 disability considered to be the medium (IRR = 1.26).

    Full Text Available Aiming to know which local characteristics influence the own tax revenues of municipalities in Minas Gerais, the bibliographic referential of this article versa on federalism and fiscal decentralization, indicating variables identified in the literature as determinants of municipal tax collection. The own tax revenues depends mainly on municipal tax bases and the rates levied on these bases. Thus, the municipality's income, as well as the weight of urban activities and the degree of formalization of economic activity, determine the size of this tax base and consequently the amount of funds raised. To analyze the local characteristics, secondary data were collected on the fiscal capacity of Minas Gerais municipalities for 2010, in view of the availability of data for this year. Was used factor analysis to group the variables, and quantile regression (RQ to check the effect of these in different stages of Municipal Own Revenues (MOR. Were obtained three factors: "Economic Aspects"; "Structural Aspects" and "Financial Aspects", which grouped the variables according to the correlation shown between them. With the RQ could be seen that these factors affect differently the quantile MOR (q.10, q.25, q.50, q.75 and q.90, and the highest rates are attributed to higher own tax revenues levels, demonstrating that these factors are most influential in the municipalities of higher own tax revenues. Knowing the conditions of own revenues of municipalities allows the public administration to implement actions to avoid the tax collection inefficiency, promoting the main economic activities that make up your tax base.

  3. Characteristic sounds facilitate visual search.

    In a natural environment, objects that we look for often make characteristic sounds. A hiding cat may meow, or the keys in the cluttered drawer may jingle when moved. Using a visual search paradigm, we demonstrated that characteristic sounds facilitated visual localization of objects, even when the sounds carried no location information. For example, finding a cat was faster when participants heard a meow sound. In contrast, sounds had no effect when participants searched for names rather than pictures of objects. For example, hearing "meow" did not facilitate localization of the word cat. These results suggest that characteristic sounds cross-modally enhance visual (rather than conceptual) processing of the corresponding objects. Our behavioral demonstration of object-based cross-modal enhancement complements the extensive literature on space-based cross-modal interactions. When looking for your keys next time, you might want to play jingling sounds.

    2006-01-01

    Full Text Available Complex relationships, following from numerous and complex links between the social-economic factors and the natural advantages of the area (favorable positions of hills and valleys in the relief, availability of water and waterfowls, a moderate continental climate, and a great wealth of high-quality agricultural surfaces are the basis for the development of the villages and of the agricultural production in the Ljig municipality. Research has been conducted with the purpose of showing, on the basis of available resources of the municipality, how the agriculture and village spaces could best be developed, towards an optimum; local marketable surpluses of farm products could be processed, industrially, for sale, and this means that the existing industrial capacities should be better used and new ones built. Also, the natural and human resources could be used in the servicing sector, and in other non-agricultural businesses. On the basis of analyzed factors, our results suggest that in the Ljig municipality, further development must be based on improvements in the rural zones as multifunctional and integral; these must serve for production, but also for social and cultural purposes. The farms should become economically stronger, and they should more elastically take part in the market economy, using an adequate combination of factors such as: natural resources, demographic processes, and connectedness by traffic infrastructure and other infra- and supra-structures.

    1977-01-01

    Radio sounding of the plasmapause from a geostationary satellite has been investigated to observe time variations of the plasmapause structure and effects of the plasma convection. In the equatorial plane, the plasmapause is located, on the average, at 4 R sub(E) (R sub(E); Earth radius), and the plasma density drops outwards from 10 2 -10 3 /cm 3 to 1-10/cm 3 in the plasmapause width of about 600 km. Plasmagrams showing a relation between the virtual range and sounding frequencies are computed by ray tracing of LF-VLF waves transmitted from a geostationary satellite, using model distributions of the electron density in the vicinity of the plasmapause. The general features of the plasmagrams are similar to the topside ionograms. The plasmagram has no penetration frequency such as f 0 F 2 , but the virtual range of the plasmagram increases rapidly with frequency above 100 kHz, since the distance between a satellite and wave reflection point increases rapidly with increasing the electron density inside the plasmapause. The plasmapause sounder on a geostationary satellite has been designed by taking account of an average propagation distance of 2 x 2.6 R sub(E) between a satellite (6.6 R sub(E)) and the plasmapause (4.0 R sub(E)), background noise, range resolution, power consumption, and receiver S/N of 10 dB. The 13-bit Barker coded pulses of baud length of 0.5 msec should be transmitted in direction parallel to the orbital plane at frequencies for 10 kHz-2MHz in a pulse interval of 0.5 sec. The transmitter peak power of 70 watts and 700 watts are required respectively in geomagnetically quiet and disturbed (strong nonthermal continuum emissions) conditions for a 400 meter cylindrical dipole of 1.2 cm diameter on the geostationary satellite. This technique will open new area of radio sounding in the magnetosphere. (auth.)

    2016-01-01

    Full Text Available Border municipalities in eastern Serbia have peripheral position in relation to the central state territory: geographical distance from the administrative, political, economic and cultural center shaping their overall social development, which is generally far behind the devel­opment of other parts of Serbia. At various stages of transition, starting from the nineties to the present, the border municipalities were, it seems, more exposed to the negative effects of the neoliberal development strategy: there was a change of ownership of industry, as well as a deindustrialization, which led to significant reduction of the workforce. The devastation of the economies in these areas has intensified negative demographic processes in the border municipalities of Eastern Serbia with the onset of the economic crisis in the eighties and the subsequent processes there caused: (a depopulation (population between census periods from 1991 to 2011 fell by more than 20% of the territory of Bor district, (b reduction in the birth rate, which for decades was showing negative trends (eg. natural growth rate in the Negotin krajina, according to the Census of 2011, amounts to -6.7 % annually (v migration of the young, working population (Census 2011 shows that nearly one-quarter of the economically active population of the Bor district 'work abroad', ie. employment is found in western European countries, they educate their own children there and, apparently, do not intend to return to the place of birth. The devastation of the economy leads to a legitimate social devastation and collapse of culture (Mitrović, 2009 and education. The main parameter to be monitored in the new neoliberal strategies of development is economic growth, which points to the direction of changes in macroeconomic processes, but not to the improvement of the quality of life of people who participate in these processes.

  13. LEAP: local environmental action plan. Municipality of Dolneni

    International Nuclear Information System (INIS)

    2004-01-01

    The Municipality of Dolneni is situated in the northern part of the Pelagonia Valley, at about 600 meters above the sea level. It is surrounded on three sides (north, northeast, east and northwest) by the mountain massifs of Dautica, Babuna and Busova Planina. The assesment of the state of the environment in the Municipality of Dolneni presented in this document is based on several principles, including, before all, human health, as well as impacts from human activities on urban and natural environment, social and economic development, etc. The impacts from environmental pollution on human health in the Municipality of Dolneni are evident. Major problem is the lack of sewerage system to collect wastewater and absence of organized landfill(s) for solid waste disposal. In addition, the improper drinking water supply in most of the settlements contributes to the increased human health risk in the Municipality. The absence of urban planning has lead to developments and uncontrolled use of natural resources that cause degradation of the environment and consequently decrease in quality of living for the population. The above problems affect the quality of living conditions and human health both directly and indirectly. In recent years, incidence of epidemics of communicable hepatitis was recovered (Debreste, Desovo), and there is a concern for a high risk of appearance of intestinal and other infectious diseases. There are no indicators of the soil quality of surface running water resources with regard to pollution. In any case, on the basis of the manner of land use and specific human activities on the territory of the Municipality, as well as on the basis of the above mentioned solid waste and waste water related problems, it may be concluded that these resources are in a rather poor condition. Other aspects of determining the quality of the environment (atmosphere, noise, natural ecosystems and biodiversity in general) are not under serious human pressure at present

    To describe how registered nurses (RNs) perceive delegation to unlicensed personnel (UP) in a municipal healthcare context in Sweden. Within municipal health care RNs often delegate tasks to UP. The latter have practical training, but lack formal competence. Twelve RNs were interviewed and the material was analysed using a phenomenographic approach. Owing to a shortage of RNs, delegation is seen as a prerequisite for a functioning organization. This necessity also involves a number of perceived contradictions in three areas: (1) the work situation of RNs - facilitation and relief vs. lack of control, powerlessness, vagueness regarding responsibility, and resignation; (2) the relationship with unlicensed personnel - stimulation, possibility for mentoring, use of UP competence and the creation of fairness vs. questioning UP competence; and (3) The patients - increase in continuity, quicker treatment, and increased security vs. insecurity (with respect to, for example, the handling of medicine). Registered nurses perceptions of delegation within municipal healthcare involve their own work situation, the UP and the patients. Registered nurses who delegate to UP must be given time for mentoring such that the nursing care is safe care of high quality. © 2011 The Authors.

  15. The relationship between the Municipal Master Plan and local Watershed Plans in water management

    Directory of Open Access Journals (Sweden)

    2015-07-01

    Full Text Available The National Water Resources Policy has as one of its tools the drafting of local Water Resource Plans. In view of water resources planning and its relationship to land use planning, the aim of this work is to analyze the institutional and legal difficulties and the potential for an integrated system of water resources management. For this, we used the method of documentary and bibliographic research, beginning with the “Estatuto da Cidade”, a law for urban policy in Brazil, and literature on water management at the municipal and watershed levels. At the municipal level, the “Master Plan” (municipal plan of land use planning became the main instrument of territorial and municipal management, defining the parameters for the compliance of social, environmental and economic functions of real property. In this sense, the municipalities have a responsibility to protect water resources and, without local support, territorial and water management cannot be integrated in the context of the river basin. Despite the difficulties of including environmental variable in urban planning, the Master Plan has the potential to shape local water management systems that are environmentally sustainable and that progressively improve water quality and quantity within the watershed. Similarly, with more significant participation of the municipality in the Basin Committee, it is possible that the forms of municipal land use and occupation can be considered during the development and implementation of the Basin Plan. Thus, the management of water resources can occur integrally.

  16. Biogas Production Potential from Economically Usable Green Waste

    Full Text Available Biomass production for energy purposes on agricultural land competes with food production. This is a serious problem, considering the limited availability of farmland, rising demand for varied food products, demand for more organic crop production resulting in considerably reduced yields per area and the need for more environmentally sound agricultural practices meeting long-term sustainability criteria. Residual land currently not used for agricultural production has been considered a promising resource, but in terms of potentials, difficult to estimate for biomass for use in the energy sector. Biomass potentials associated with “green waste” from residual grasslands were assessed for Schwäbisch Hall County in the Federal State of Baden-Württemberg, Germany. Roadside edges, conservation grasslands subject to low intensity use (landscape maintenance sites, riparian stretches along ditches and streams, and municipal green spaces (public lawns, parks and sports fields were the area types considered. Data for biomass and biogas yields were either determined through a sampling program or obtained from the literature and through interviews with experts. In an iterative process and distinguishing between theoretical, technical and realized (economic potentials, unsuitable areas and fractions were subtracted from the theoretical potentials. Theoretical potentials for Schwäbisch Hall County were originally estimated at 21 million m3 of biogas. The results of the investigation suggest that a very high percentage of the theoretical residual biomass potential cannot be accessed due to various technical, legal, ecological or management (economic constraints. In fact, in the end, only municipal lawns and green spaces were found to provide suitable substrates. Current use of residual biomass in the model communities did not exceed 0.4% of the theoretical potentials. Provided all residual biomass available under current management practices

  18. National parks and local development in Poland: A municipal perspective

    Directory of Open Access Journals (Sweden)

    Bernadetta Zawilińska

    2013-05-01

    Full Text Available The article is addressing the problem of local authorities seeing in national parks a stimulus or a barrier for local development in Poland. The results of surveys conducted among representatives of authorities of selected municipalities (n=61, in which there are national park areas show that the assessment of the role and impact of this type of protected areas varies. In most cases the presence of national parks is viewed positively. Emphasis is put on their importance to the local socio-economic development. The economic benefit is seen mainly in the tourism sector and the development of associated services. However, local communities experience many restrictions resulting from functioning of protected areas, especially in regard to the possibility of increasing revenues to the budgets of municipalities, production entrepreneurship development and intensification of agricultural production and fisheries. It is believed that in the future parks should stimulate local development to a larger extent. To achieve this, it is necessary to see a national park as a system linked to the socio-economic environment and to take planning actions based on a holistic look at natural, social and economic issues of a national park and its neighbourhood. The cooperation between local authorities, parks’ management, non-governmental organisations and local tourism business should be strengthened as well as steps should be taken in order to increase social participation in shaping the development of these areas.

  19. Sound Velocity in Soap Foams

    2012-01-01

    The velocity of sound in soap foams at high gas volume fractions is experimentally studied by using the time difference method. It is found that the sound velocities increase with increasing bubble diameter, and asymptotically approach to the value in air when the diameter is larger than 12.5 mm. We propose a simple theoretical model for the sound propagation in a disordered foam. In this model, the attenuation of a sound wave due to the scattering of the bubble wall is equivalently described as the effect of an additional length. This simplicity reasonably reproduces the sound velocity in foams and the predicted results are in good agreement with the experiments. Further measurements indicate that the increase of frequency markedly slows down the sound velocity, whereas the latter does not display a strong dependence on the solution concentration

  20. Analysis of environmental sounds

    Science.gov (United States)

    Lee, Keansub

    Environmental sound archives - casual recordings of people's daily life - are easily collected by MPS players or camcorders with low cost and high reliability, and shared in the web-sites. There are two kinds of user generated recordings we would like to be able to handle in this thesis: Continuous long-duration personal audio and Soundtracks of short consumer video clips. These environmental recordings contain a lot of useful information (semantic concepts) related with activity, location, occasion and content. As a consequence, the environment archives present many new opportunities for the automatic extraction of information that can be used in intelligent browsing systems. This thesis proposes systems for detecting these interesting concepts on a collection of these real-world recordings. The first system is to segment and label personal audio archives - continuous recordings of an individual's everyday experiences - into 'episodes' (relatively consistent acoustic situations lasting a few minutes or more) using the Bayesian Information Criterion and spectral clustering. The second system is for identifying regions of speech or music in the kinds of energetic and highly-variable noise present in this real-world sound. Motivated by psychoacoustic evidence that pitch is crucial in the perception and organization of sound, we develop a noise-robust pitch detection algorithm to locate speech or music-like regions. To avoid false alarms resulting from background noise with strong periodic components (such as air-conditioning), a new scheme is added in order to suppress these noises in the domain of autocorrelogram. In addition, the third system is to automatically detect a large set of interesting semantic concepts; which we chose for being both informative and useful to users, as well as being technically feasible. These 25 concepts are associated with people's activities, locations, occasions, objects, scenes and sounds, and are based on a large collection of

    I recently accompanied my son Dan to one of his guitar lessons. As I sat in a separate room, I focused on the music he was playing and the beautiful, robust sound that comes from a well-played guitar. Later that night, I woke up around 3 am. I tend to have my best thoughts at this hour. The trouble is I usually roll over and fall back asleep. This time I was still awake an hour later, so I got up and jotted some notes down in my study. I was thinking about the pure, honest sound of a well-played instrument. From there my mind wandered into the realm of high-performance teams and successful projects. (I know this sounds weird, but this is the sort of thing I think about at 3 am. Maybe you have your own weird thoughts around that time.) Consider a team in relation to music. It seems to me that a crack team can achieve a beautiful, perfect unity in the same way that a band of brilliant musicians can when they're in harmony with one another. With more than a little satisfaction I have to admit, I started to think about the great work performed for you by the Knowledge Sharing team, including this magazine you are reading. Over the past two years I personally have received some of my greatest pleasures as the APPL Director from the Knowledge Sharing activities - the Masters Forums, NASA Center visits, ASK Magazine. The Knowledge Sharing team expresses such passion for their work, just like great musicians convey their passion in the music they play. In the case of Knowledge Sharing, there are many factors that have made this so enjoyable (and hopefully worthwhile for NASA). Three ingredients come to mind -- ingredients that have produced a signature sound. First, through the crazy, passionate playing of Alex Laufer, Michelle Collins, Denise Lee, and Todd Post, I always know that something startling and original is going to come out of their activities. This team has consistently done things that are unique and innovative. For me, best of all is that they are always

    2017-12-01

    'Musical Sound, Instruments, and Equipment' offers a basic understanding of sound, musical instruments and music equipment, geared towards a general audience and non-science majors. The book begins with an introduction of the fundamental properties of sound waves, and the perception of the characteristics of sound. The relation between intensity and loudness, and the relation between frequency and pitch are discussed. The basics of propagation of sound waves, and the interaction of sound waves with objects and structures of various sizes are introduced. Standing waves, harmonics and resonance are explained in simple terms, using graphics that provide a visual understanding. The development is focused on musical instruments and acoustics. The construction of musical scales and the frequency relations are reviewed and applied in the description of musical instruments. The frequency spectrum of selected instruments is explored using freely available sound analysis software. Sound amplification and sound recording, including analog and digital approaches, are discussed in two separate chapters. The book concludes with a chapter on acoustics, the physical factors that affect the quality of the music experience, and practical ways to improve the acoustics at home or small recording studios. A brief technical section is provided at the end of each chapter, where the interested reader can find the relevant physics and sample calculations. These quantitative sections can be skipped without affecting the comprehension of the basic material. Questions are provided to test the reader's understanding of the material. Answers are given in the appendix.

The highway was strongly resisted and it became the site of one of the country’s longest and largest anti-road struggles. The chapter addresses specifically Graeme Miller’s sound walk LINKED (2003), which for more than a decade has been broadcasting memories and stories...... of people who were violently displaced by the road as well as those who actively sought to halt it. Attention is given to the walk’s interruption of senses of the given and inevitable in two main ways. The first is in relation to the pace of the work and its deployment of slowness and arrest in a context...

    Commercials offer the opportunity for intergenerational memory and impinge on cultural memory. TV commercials for foodstuffs often make reference to past times as a way of authenticating products. This is frequently achieved using visual cues, but in this paper I would like to demonstrate how...... such references to the past and ‘the good old days’ can be achieved through sounds. In particular, I will look at commercials for Danish non-dairy spreads, especially for OMA margarine. These commercials are notable in that they contain a melody and a slogan – ‘Say the name: OMA margarine’ – that have basically...... remained the same for 70 years.

  14. The sounds of science

    Science.gov (United States)

    Carlowicz, Michael

    As scientists carefully study some aspects of the ocean environment, are they unintentionally distressing others? That is a question to be answered by Robert Benson and his colleagues in the Center for Bioacoustics at Texas A&M University.With help from a 3-year, $316,000 grant from the U.S. Office of Naval Research, Benson will study how underwater noise produced by naval operations and other sources may affect marine mammals. In Benson's study, researchers will generate random sequences of low-frequency, high-intensity (180-decibel) sounds in the Gulf of Mexico, working at an approximate distance of 1 km from sperm whale herds. Using an array of hydrophones, the scientists will listen to the characteristic clicks and whistles of the sperm whales to detect changes in the animals' direction, speed, and depth, as derived from fluctuations in their calls.

  8. An Industrial Ecology Approach to Municipal Solid Waste ...

    Science.gov (United States)

    The organic fraction of municipal solid waste provides abundant opportunities for industrial ecology-based symbiotic use. Energy production, economics, and environmental aspects are analyzed for four alternatives based on different technologies: incineration with energy recovery, gasification, anaerobic digestion, and fermentation. In these cases electricity and ethanol are the products considered, but other products and attempts at symbiosis can be made. The four technologies are in various states of commercial development. To highlight their relative complexities some adjustable parameters which are important for the operability of each process are discussed. While these technologies need to be considered for specific locations and circumstances, generalized economic and environmental information suggests relative comparisons for newly conceptualized processes. The results of industrial ecology-based analysis suggest that anaerobic digestion may improve seven emission categories, while fermentation, gasification, and incineration successively improve fewer emissions. A conceptual level analysis indicates that gasification, anaerobic digestion, and fermentation alternatives lead to positive economic results. In each case the alternatives and their assumptions need further analysis for any particular community. Presents information useful for analyzing the sustainability of alternatives for the management of municipal solid waste.

    2017-12-01

    The production of municipal solid waste (MSW) represents one of the greatest challenges currently faced by waste managers all around the world. In Brazil, the situation with regard to solid waste management is still deficient in many aspects. In 2015, only 58.7% of the MSW collected in Brazilian cities received appropriate final disposal. It was only as late as 2010 that Brazil established the National Policy on Solid Waste (NPSW) based on the legislation and programmes established in the 1970s in more developed countries. However, the situation with regard to MSW management has changed little since the implementation of the NPSW. Recent data show that, in Brazil, disposal in sanitary landfills is practically the only management approach to MSW. Contrary to expectations, despite the economic recession in 2015 the total annual amount of MSW generated nationwide increased by 1.7%, while in the same period the Brazilian population grew by 0.8% and economic activity decreased by 3.8%. The article describes the panorama with regard to MSW in Brazil from generation to final disposal and discusses the issues related to the delay in implementing the NPSW. The collection of recyclable material, the recycling process, the application of reverse logistics and the determination of the gravimetric composition of MSW in Brazil are also addressed in this article. Finally, a brief comparison is made between MSW management in Brazil and in other countries, the barriers to developing effective waste disposal systems are discussed and some recommendations for future MSW management development in Brazil are given.

    Troschinetz, Alexis M.; Mihelcic, James R.

    2009-01-01

    This research focuses on recycling in developing countries as one form of sustainable municipal solid waste management (MSWM). Twenty-three case studies provided municipal solid waste (MSW) generation and recovery rates and composition for compilation and assessment. The average MSW generation rate was 0.77 kg/person/day, with recovery rates from 5-40%. The waste streams of 19 of these case studies consisted of 0-70% recyclables and 17-80% organics. Qualitative analysis of all 23 case studies identified barriers or incentives to recycling, which resulted in the development of factors influencing recycling of MSW in developing countries. The factors are government policy, government finances, waste characterization, waste collection and segregation, household education, household economics, MSWM (municipal solid waste management) administration, MSWM personnel education, MSWM plan, local recycled-material market, technological and human resources, and land availability. Necessary and beneficial relationships drawn among these factors revealed the collaborative nature of sustainable MSWM. The functionality of the factor relationships greatly influenced the success of sustainable MSWM. A correlation existed between stakeholder involvement and the three dimensions of sustainability: environment, society, and economy. The only factors driven by all three dimensions (waste collection and segregation, MSWM plan, and local recycled-material market) were those requiring the greatest collaboration with other factors

    Full Text Available The economical crisis that hit Greece after 2009, significantly affected its energy consumption profile due to the increased price of domestic heating oil and gasoline. The specific study aims at the quantification of the carbon dioxide emissions in municipal level due to energy and fuel consumption. Three different municipalities in North Greece (Kavala, Alexandroupolis and Drama were assessed with the application of three different carbon footprint estimation approaches in each one of them, including two life cycle assessment methods. Results ranged from 511,799 to 571,000, 435,250 to 489,000 and 355,207 to 398,000 tons CO2 and tons CO2-eq. for Kavala, Alexandroupolis and Drama respectively. The analysis per energy type indicated the electrical energy consumption as the key factor affecting the results due to the relatively high CO2 emission coefficient of the electricity produced in Greece. The analysis per sector indicated that a percentage of nearly 75% of the total carbon footprint is assigned to the building sector whereas the private and commercial transport is accountable for the rest. Municipal activities (buildings, facilities, lighting and fleet contributed to a small percentage to the total carbon footprint (approx. 3-8%.

    Trump, J.G.; Wright, K.A.; Sinskey, A.J.; Shah, D.N.; Fernald, R.

    1979-01-01

    Laboratory studies at M.I.T. and high flow rate studies at the M.D.C. Deer Island Wastewater Treatment Plant in Boston have shown the practicality and cost effectiveness of disinfecting liquid municipal sludges by injecting energized electrons. A dosage of 400 Kilorads (4 Kilograys) reduces gram-negative bacteria, including coliforms, fecal coliforms, salmonellae and shigellae, in primary raw or anaerobically digested sludges to undetectable levels. Enteric viruses are reduced by one to two orders of magnitude. This treatment also destroys parasite eggs or renders them non-infectious. Model system studies indicate that trace toxic compounds such as PCBs in water are degraded. The estimated cost of sludge disinfection by electron treatment is about $0.80 per liquid tonne for modular systems of 650 liquid tonnes per day capacity. About 6 Kilowatt-hours of input electric power per tonne is required. The temperature rise of the disinfected watery sludge is about 2 0 C. Electron disinfection combined with subsurface soil injection offers an environmentally attractive, energy-efficient, and economic two -step process for land disposal of municipal sludges with water conservation and soil improvement benefits. Combined with widely-distributed ocean feeding, electron disinfection of the municipal sludge of coastal communities offers a safe marine nutrient for increasing fish population in treated ocean areas. The electron disinfection of effluent wastewater, in lieu of chlorination, is a future application which avoids the production of potentially toxic chlorinated hydrocarbons. (Author) [pt

  19. Sustainable kerbside recycling in the municipal garbage contract.

    Science.gov (United States)

    Chowdhury, Moe

    2009-12-01

    In an era of global warming, rising energy costs and increasing volumes of wastes destined for landfills and incinerators, communities should set up environmentally sustainable services that are cost-effective for their citizens and revenue generators for municipalities. A win-win garbage collection and kerbside recycling program established more than eight years ago in a small rural community in Ohio, US is still going strong. It is offering a relatively inexpensive way for waste disposal by providing an incentive-based and highly participatory kerbside recycling and at the same time bringing in substantial franchise fees for the municipal coffers. Unlike garbage contracts in most communities that are designed for only residential waste collection, this program extends disposal and recycling services to non-residential establishments. It picks up hard-to-dispose household furniture, appliances and other bulky items without additional costs to the residents. By being creative and assessing local political and socio-economic milieu, public officials can implement a comprehensive service package for taking care of their community throwaways. However, before establishing such programs in partnership with a private firm, city administrators must understand the intricacies of bid specifications customized for municipal wastes and recyclable materials.

  8. An exploration into municipal waste charges for environmental management at local level: The case of Spain.

    Science.gov (United States)

    Puig-Ventosa, Ignasi; Sastre Sanz, Sergio

    2017-11-01

    Municipal waste charges have been widely acknowledged as a crucial tool for waste management at the local level. This is because they contribute to financing the costly provision of waste collection and treatment services and they can be designed to provide an economic stimulus to encourage citizens and local businesses to improve separate collection and recycling. This work presents a methodology to evaluate a sample of 125 municipal waste charges in Spain for the year 2015, covering 33.91% of the Spanish population. The qualitative benchmarking of municipal waste charges shows that flat fees are frequent, whereas variable fees are set according to criteria that are weakly related to waste generation. The average fee per household is €82.2 per year, which does not provide full cost recovery. The current configuration of municipal waste charges penalises taxpayers contributing to source separation of waste, while subsidising less environmentally friendly behaviours. In this sense, municipal waste charges in Spain are far from applying the polluter pays principle. Furthermore, it is argued that municipal waste charges are ineffective for promoting the proper application of the so-called 'waste hierarchy'.

    During the first half of this year (CY 1996), the EUVS project began preparations of the EUVS payload for the upcoming NASA sounding rocket flight 36.148CL, slated for launch on July 26, 1996 to observe and record a high-resolution (approx. 2 A FWHM) EUV spectrum of the planet Venus. These preparations were designed to improve the spectral resolution and sensitivity performance of the EUVS payload as well as prepare the payload for this upcoming mission. The following is a list of the EUVS project activities that have taken place since the beginning of this CY: (1) Applied a fresh, new SiC optical coating to our existing 2400 groove/mm grating to boost its reflectivity; (2) modified the Ranicon science detector to boost its detective quantum efficiency with the addition of a repeller grid; (3) constructed a new entrance slit plane to achieve 2 A FWHM spectral resolution; (4) prepared and held the Payload Initiation Conference (PIC) with the assigned NASA support team from Wallops Island for the upcoming 36.148CL flight (PIC held on March 8, 1996; see Attachment A); (5) began wavelength calibration activities of EUVS in the laboratory; (6) made arrangements for travel to WSMR to begin integration activities in preparation for the July 1996 launch; (7) paper detailing our previous EUVS Venus mission (NASA flight 36.117CL) published in Icarus (see Attachment B); and (8) continued data analysis of the previous EUVS mission 36.137CL (Spica occultation flight).

  12. Sound Clocks and Sonic Relativity

    2017-10-01

    Sound propagation within certain non-relativistic condensed matter models obeys a relativistic wave equation despite such systems admitting entirely non-relativistic descriptions. A natural question that arises upon consideration of this is, "do devices exist that will experience the relativity in these systems?" We describe a thought experiment in which `acoustic observers' possess devices called sound clocks that can be connected to form chains. Careful investigation shows that appropriately constructed chains of stationary and moving sound clocks are perceived by observers on the other chain as undergoing the relativistic phenomena of length contraction and time dilation by the Lorentz factor, γ , with c the speed of sound. Sound clocks within moving chains actually tick less frequently than stationary ones and must be separated by a shorter distance than when stationary to satisfy simultaneity conditions. Stationary sound clocks appear to be length contracted and time dilated to moving observers due to their misunderstanding of their own state of motion with respect to the laboratory. Observers restricted to using sound clocks describe a universe kinematically consistent with the theory of special relativity, despite the preferred frame of their universe in the laboratory. Such devices show promise in further probing analogue relativity models, for example in investigating phenomena that require careful consideration of the proper time elapsed for observers.

    Full Text Available OBJECTIVE: The aim of this study was to determine the effects of occupational noise on sound localization in different spatial planes and frequencies among normal hearing firefighters. METHOD: A total of 29 adults with pure-tone hearing thresholds below 25 dB took part in the study. The participants were divided into a group of 19 firefighters exposed to occupational noise and a control group of 10 adults who were not exposed to such noise. All subjects were assigned a sound localization task involving 117 stimuli from 13 sound sources that were spatially distributed in horizontal, vertical, midsagittal and transverse planes. The three stimuli, which were square waves with fundamental frequencies of 500, 2,000 and 4,000 Hz, were presented at a sound level of 70 dB and were randomly repeated three times from each sound source. The angle between the speaker's axis in the same plane was 45°, and the distance to the subject was 1 m. RESULT: The results demonstrate that the sound localization ability of the firefighters was significantly lower (p<0.01 than that of the control group. CONCLUSION: Exposure to occupational noise, even when not resulting in hearing loss, may lead to a diminished ability to locate a sound source.

    The Puget Sound Area Electric Reliability Plan Draft Environmental Impact Statement (DEIS) identifies the alternatives for solving a power system problem in the Puget Sound area. This Plan is undertaken by Bonneville Power Administration (BPA), Puget Sound Power & Light, Seattle City Light, Snohomish Public Utility District No. 1 (PUD), and Tacoma Public Utilities. The Plan consists of potential actions in Puget Sound and other areas in the State of Washington. A specific need exists in the Puget Sound area for balance between east-west transmission capacity and the increasing demand to import power generated east of the Cascades. At certain times of the year, there is more demand for power than the electric system can supply in the Puget Sound area. This high demand, called peak demand, occurs during the winter months when unusually cold weather increases electricity use for heating. The existing power system can supply enough power if no emergencies occur. However, during emergencies, the system will not operate properly. As demand grows, the system becomes more strained. To meet demand, the rate of growth of demand must be reduced or the ability to serve the demand must be increased, or both. The plan to balance Puget Sound`s power demand and supply has these purposes: The plan should define a set of actions that would accommodate ten years of load growth (1994--2003). Federal and State environmental quality requirements should be met. The plan should be consistent with the plans of the Northwest Power Planning Council. The plan should serve as a consensus guideline for coordinated utility action. The plan should be flexible to accommodate uncertainties and differing utility needs. The plan should balance environmental impacts and economic costs. The plan should provide electric system reliability consistent with customer expectations. 29 figs., 24 tabs.

    With the evolutionary change in the production activities of human societies, the concept of development has also been changing. In the recent years the emphasis has been on the environmentally sound and sustainable development. The environmentally sound and sustainable development can be obtained through judicious use of technology. Technology as a resource transformer has emerged as the most important factor which can constitute to economic growth. But technology is not an independent and autonomous force, it is only an instrument which needs to be used carefully, properly and appropriately which necessitates technology management. (author)

    Full Text Available Urbanization tends bring out a number of problems, such as inadequate housing and urban services, increase land prices and construction costs, propagation of slums, pollution and deterioration of the urban environment. Currently, spatial development activities focusing on major cities of Sri Lanka are demanding urban infrastructure and services where municipalities are facing challenges on provision of the infrastructure and proper urban management too. This study seeks to identify the relevant criteria, indicators and a method for assessing the urban management performance of municipalities in Sri Lanka since specific measurement criteria and related indicators are not yet identified to evaluate urban management by the central government or local government levels. Based on Literature review, five criteria and 25 indicators were selected considering their applicability for the context of Sri Lanka. The Full Permutation Polygon Synthetic Indicator Method (FPPSI was applied to synthesize indicators and the Synthetic indicator has been used to show the performance of each criterion in terms of urban service delivery. Colombo Municipal Council (CMC, Sri Jayawardenapura Kotte Municipal Council (SJKMC and Moratuwa Municipal Council (MMC have been selected as the case studies for this research. Although selected cases are within Colombo Metropolitan Region, none of the municipalities were achieved the “High” or “Very High” level of synthetic indicator (SR>= 0.50 that shows the standard of municipal service delivery of Sri Lanka as a whole. This research lays the platform to evaluate the functional performance of Municipal Councils to guide the future scenario and to make decisions at the grass root level for managing the urbanization related issues in the country. Also this research helps the government to know the current trends of development impact and to take necessary policy level decisions to guide the economic growth in a correct

    We compute fourth sound for superfluids dual to a charged scalar and a gauge field in an AdS 4 background. For holographic superfluids with condensates that have a large scaling dimension (greater than approximately two), we find that fourth sound approaches first sound at low temperatures. For condensates that a have a small scaling dimension it exhibits non-conformal behavior at low temperatures which may be tied to the non-conformal behavior of the order parameter of the superfluid. We show that by introducing an appropriate scalar potential, conformal invariance can be enforced at low temperatures.

    The construction of an electric generating station may have socio-economic effects upon the community in which it is located. Among the possible effects during construction are changes in population leading to strains in housing, schools, employment, transportation, and increased demands on local government services. The scale of the effects varies according to the population base of the county in which the plant is located and the distance of the site from major metropolitan areas. Increased demands for county and municipal public services also vary during the construction period. In some instances the increased cost of public services can result in large budget deficits at both the county and municipal level as construction period revenue increases fail to keep pace with service costs. In the study case of potential Eastern Shore power plant sites, annual municipal budget deficits were estimated to range from 3 to 21% for nuclear plant construction. The same study projected the largest county deficit at 4%, with other counties experiencing revenues and expenditures which were essentially in balance. After a new plant starts operation, the tax revenue to county government is on the order of several million dollars per year or greater depending on plant size and local tax rates, and the service costs are small

The article strongly challenges the view that the cause of informal settlements in EMM and other parts of South Africa is predominantly the apartheid government and agrees with literature which provides evidence that to a larger extent, the present government, not the apartheid government, is one of the dominant causes of informal settlements. The article further establishes a common and fertile ground for the convergence of the different views and perspectives into variables which, in addition to the present government, include population growth, government economic policies, economic variables, housing shortage, unavailability of land and unaffordability as the real causes of informal settlements in EMM.

  6. An industrial ecology approach to municipal solid waste ...

    Science.gov (United States)

    Municipal solid waste (MSW) can be viewed as a feedstock for industrial ecology inspired conversions of wastes to valuable products and energy. The industrial ecology principle of symbiotic processes using waste streams for creating value-added products is applied to MSW, with examples suggested for various residual streams. A methodology is presented to consider individual waste-to-energy or waste-to-product system synergies, evaluating the economic and environmental issues associated with each system. Steps included in the methodology include identifying waste streams, specific waste components of interest, and conversion technologies, plus steps for determining the economic and environmental effects of using wastes and changes due to transport, administrative handling, and processing. In addition to presenting the methodology, technologies for various MSW input streams are categorized as commercialized or demonstrated to provide organizations that are considering processes for MSW with summarized information. The organization can also follow the methodology to analyze interesting processes. Presents information useful for analyzing the sustainability of alternatives for the management of municipal solid waste.

    The economic and environmental problems of handling the increasingly huge amounts of urban and/or suburban organic municipal solid wastes MSW, from collection to end disposal, in addition to the big fluctuations in power supply and other energy form costs for the various civilian needs, is studied for Baghdad city, the ancient and glamorous capital of Iraq, and a simple control device is suggested, built and tested by carbonizing these dried organic wastes in simple environment friendly bio-reactor in order to produce low pollution potential, economical and local charcoal capsules that might be useful for heating, cooking and other municipal uses. That is in addition to the solve of solid wastes management problem which involves huge human and financial resources and causes many lethal health and environmental problems. Leftovers of different social level residential campuses were collected, classified for organic materials then dried in order to be supplied into the bio-reactor, in which it is burnt and then mixed with small amounts of sugar sucrose that is extracted from Iraqi planted sugar cane, to produce well shaped charcoal capsules. The burning process is smoke free as the closed burner’s exhaust pipe is buried 1m underground hole, in order to use the subsurface soil as natural gas filter. This process has proved an excellent performance of handling about 120kg/day of classified MSW, producing about 80-100 kg of charcoal capsules, by the use of 200 l reactor volume.

  8. Statistics of natural binaural sounds.

    Directory of Open Access Journals (Sweden)

    Wiktor Młynarski

    Full Text Available Binaural sound localization is usually considered a discrimination task, where interaural phase (IPD and level (ILD disparities at narrowly tuned frequency channels are utilized to identify a position of a sound source. In natural conditions however, binaural circuits are exposed to a stimulation by sound waves originating from multiple, often moving and overlapping sources. Therefore statistics of binaural cues depend on acoustic properties and the spatial configuration of the environment. Distribution of cues encountered naturally and their dependence on physical properties of an auditory scene have not been studied before. In the present work we analyzed statistics of naturally encountered binaural sounds. We performed binaural recordings of three auditory scenes with varying spatial configuration and analyzed empirical cue distributions from each scene. We have found that certain properties such as the spread of IPD distributions as well as an overall shape of ILD distributions do not vary strongly between different auditory scenes. Moreover, we found that ILD distributions vary much weaker across frequency channels and IPDs often attain much higher values, than can be predicted from head filtering properties. In order to understand the complexity of the binaural hearing task in the natural environment, sound waveforms were analyzed by performing Independent Component Analysis (ICA. Properties of learned basis functions indicate that in natural conditions soundwaves in each ear are predominantly generated by independent sources. This implies that the real-world sound localization must rely on mechanisms more complex than a mere cue extraction.

    The planning of waste management strategies needs tools to support decisions at all stages of the process. Accurate quantification of the waste to be generated is essential for both the daily management (short-term) and proper design of facilities (long-term). Designing without rigorous knowledge may have serious economic and environmental consequences. The present works aims at identifying relevant socio-economic features of municipalities regarding Household Waste (HW) generation by means of factor models. Factor models face two main drawbacks, data collection and identifying relevant explanatory variables within a heterogeneous group. Grouping similar characteristics observations within a group may favour the deduction of more robust models. The methodology followed has been tested with Biscay Province because it stands out for having very different municipalities ranging from very rural to urban ones. Two main models are developed, one for the overall province and a second one after clustering the municipalities. The results prove that relating municipalities with specific characteristics, improves the results in a very heterogeneous situation. The methodology has identified urban morphology, tourism activity, level of education and economic situation as the most influencing characteristics in HW generation. Copyright © 2015 The Authors.

    Highlights: • An optimization approach for the sustainable management of municipal solid waste is proposed. • The proposed model optimizes the entire supply chain network of a distributed system. • A case study for the sustainable waste management in the central-west part of Mexico is presented. • Results shows different interesting solutions for the case study presented. - Abstract: The increasing generation of municipal solid waste (MSW) is a major problem particularly for large urban areas with insufficient landfill capacities and inefficient waste management systems. Several options associated to the supply chain for implementing a MSW management system are available, however to determine the optimal solution several technical, economic, environmental and social aspects must be considered. Therefore, this paper proposes a mathematical programming model for the optimal planning of the supply chain associated to the MSW management system to maximize the economic benefit while accounting for technical and environmental issues. The optimization model simultaneously selects the processing technologies and their location, the distribution of wastes from cities as well as the distribution of products to markets. The problem was formulated as a multi-objective mixed-integer linear programing problem to maximize the profit of the supply chain and the amount of recycled wastes, where the results are showed through Pareto curves that tradeoff economic and environmental aspects. The proposed approach is applied to a case study for the west-central part of Mexico to consider the integration of MSW from several cities to yield useful products. The results show that an integrated utilization of MSW can provide economic, environmental and social benefits.

    Municipalities are directly affected by the liberalization of the energy markets. Because they all consume or even produce energy, whether it be for their own consumption or to resell it, they often distribute gas, electricity or heat, they plan urban areas and organize the energy networks on their territory, while in addition citizens expect municipalities to inform them and even protect them against the possible excesses of energy salesmen. Elected representatives administrations, local agencies, municipal companies, citizens' associations etc., all have to innovate. This supplement to Energie-Cites INFO is intended to provide you with practical information and further analyses of the liberalization process. (authors)

    Acoustic Oscillations in Solar-Twin "Alpha Cen A" Observed from La Silla by Swiss Team Summary Sound waves running through a star can help astronomers reveal its inner properties. This particular branch of modern astrophysics is known as "asteroseismology" . In the case of our Sun, the brightest star in the sky, such waves have been observed since some time, and have greatly improved our knowledge about what is going on inside. However, because they are much fainter, it has turned out to be very difficult to detect similar waves in other stars. Nevertheless, tiny oscillations in a solar-twin star have now been unambiguously detected by Swiss astronomers François Bouchy and Fabien Carrier from the Geneva Observatory, using the CORALIE spectrometer on the Swiss 1.2-m Leonard Euler telescope at the ESO La Silla Observatory. This telescope is mostly used for discovering exoplanets (see ESO PR 07/01 ). The star Alpha Centauri A is the nearest star visible to the naked eye, at a distance of a little more than 4 light-years. The new measurements show that it pulsates with a 7-minute cycle, very similar to what is observed in the Sun . Asteroseismology for Sun-like stars is likely to become an important probe of stellar theory in the near future. The state-of-the-art HARPS spectrograph , to be mounted on the ESO 3.6-m telescope at La Silla, will be able to search for oscillations in stars that are 100 times fainter than those for which such demanding observations are possible with CORALIE.

The Plan consists of potential actions in Puget Sound and other areas in the State of Washington. A specific need exists in the Puget Sound area for balance between east-west transmission capacity and the increasing demand to import power generated east of the Cascades. At certain times of the year, there is more demand for power than the electric system can supply in the Puget Sound area. This high demand, called peak demand, occurs during the winter months when unusually cold weather increases electricity use for heating. The existing power system can supply enough power if no emergencies occur. However, during emergencies, the system will not operate properly. As demand grows, the system becomes more strained. To meet demand, the rate of growth of demand must be reduced or the ability to serve the demand must be increased, or both. The plan to balance Puget Sound's power demand and supply has these purposes: The plan should define a set of actions that would accommodate ten years of load growth (1994--2003). Federal and State environmental quality requirements should be met. The plan should be consistent with the plans of the Northwest Power Planning Council. The plan should serve as a consensus guideline for coordinated utility action. The plan should be flexible to accommodate uncertainties and differing utility needs. The plan should balance environmental impacts and economic costs. The plan should provide electric system reliability consistent with customer expectations. 29 figs., 24 tabs.

    The strong acceptance for vehicles powered by turbo-charged diesel engines encourages several manufacturers to think about sportive diesel concepts. The approach of suppressing unpleasant noise by the application of distinctive insulation steps is not adequate to satisfy sportive needs. The acoustics cannot follow the engine's performance. This report documents, that it is possible to give diesel-powered vehicles a sportive sound characteristic by using an advanced MAHLE motor-sound-system with a pressure-resistant membrane and an integrated load controlled flap. With this the specific acoustic disadvantages of the diesel engine, like the ''diesel knock'' or a rough engine running can be masked. However, by the application of a motor-sound-system you must not negate the original character of the diesel engine concept, but accentuate its strong torque characteristic in the middle engine speed range.

    separation techniques make it possible to distinguish between outgoing and incoming waves from the two sides, and thus NAH can be applied. In this paper, a separation method based on the measurement of the particle velocity in two layers and another method based on the measurement of the pressure...... and the velocity in a single layer are proposed. The two methods use an equivalent source formulation with separate transfer matrices for the outgoing and incoming waves, so that the sound from the two sides of the array can be modeled independently. A weighting scheme is proposed to account for the distance......In conventional near-field acoustic holography (NAH) it is not possible to distinguish between sound from the two sides of the array, thus, it is a requirement that all the sources are confined to only one side and radiate into a free field. When this requirement cannot be fulfilled, sound field...

  4. Sounds of silence: How to animate virtual worlds with sound

    Astheimer, Peter

    1993-01-01

    Sounds are an integral and sometimes annoying part of our daily life. Virtual worlds which imitate natural environments gain a lot of authenticity from fast, high quality visualization combined with sound effects. Sounds help to increase the degree of immersion for human dwellers in imaginary worlds significantly. The virtual reality toolkit of IGD (Institute for Computer Graphics) features a broad range of standard visual and advanced real-time audio components which interpret an object-oriented definition of the scene. The virtual reality system 'Virtual Design' realized with the toolkit enables the designer of virtual worlds to create a true audiovisual environment. Several examples on video demonstrate the usage of the audio features in Virtual Design.

    Improved fiscal management is a frequent justification for promoting boundary consolidations. However, whether or not this is actually the case is rarely placed under rigorous empirical scrutiny. Hence, this article investigates if fiscal outcomes are improved when municipalities are merged....... The basic argument is that the conceptualisation of fiscal management in political science is often too narrow as it focuses on the budget and pays hardly any attention to balances in the final accounts and debts – elements of management which are central to policy making. On this background, the causal...... relationship between municipal mergers and fiscal outcomes is analysed.

    1993-12-31

    Full scale experience exists and justifies implementing anaerobic digestion for pretreatment of high strength industrial waste water and side streams. Anaerobic treatment of sludge and manure have demonstrated cost effective, environmentally sound treatment of these wastes. Recent attention has focused on the potential for anaerobically treating high solids municipal solid wastes to assist in meeting state waste reduction goals and provide a new renewable source of energy. This paper focuses on the fundamental facility design and process protocol considerations necessary for a high solids anaerobic digesting facility. The primary design and equipment considerations are being applied to a 5 to 10 ton per day demonstration anaerobic digestion facility in Bergen, New York.

  13. AWARENESS LEVEL STUDY FOR IMPLEMENTING SEPARATION OF MUNICIPAL SOLID WASTE PROGRAM IN THE MUNICIPALITY OF ARANDAS, JALISCO

    Directory of Open Access Journals (Sweden)

    Norberto Santiago-Olivares

    2017-07-01

    Full Text Available The Arandas municipality government in Jalisco, has been looking for solutions to the problem of its municipal solid waste (MSW disposal for some years. Nowadays there is a “dumping site" where these residues are deposited without any established control, promoting the generation of vermin and rodents such as: flies, cockroaches, rats, mouses, etc.; adding up to the air, soil and water pollution. The solution starts with the separation of municipal solid waste from the generation sites, but it does not make any sense to separate the waste if there is not a subsequent treatment system established. The population awareness for garbage separation at home is quite necessary, because if it is not carried out correctly, it won’t be able to give an effective further treatment to the municipal solid waste MSW generated. In countries and municipalities where garbage separation is already practiced, it was because the community is forced to do so, whether their garbage is not collected if it is not properly separated, or by the implementation of economic fines. With the support of the H. Ayuntamiento de Arandas and José Mario Molina Pasquel and Henríquez Technological Institute Campus Arandas, was carried out a study to determine the level of awareness that the population of Arandas has about the necessity to separate garbage at home. For this purpose, a survey was designed and applied to parents or guardians of students from educational institutions: CONALEP Arandas, UDG Regional High School, CBTIS and José Mario Molina Pasquel and Henríquez Technological Institute Campus Arandas. The research carried out was quantitative and descriptive type, where the selection of the sample was “for convenience” (to optimize time and costs in the application of the survey. According to the results obtained in the survey analysis, it was observed that Arandas population was concerned about the preservation of environment and they are willing to do garbage

    1993-12-31

    With the support of the US Agency for International Development, the National Rural Electric Cooperative Association (NRECA) is assisting their utility counterparts in Bolivia to improve electric service in the country`s rural population. In remote areas, the cost of extending transmission lines to small communities is prohibitive, and diesel generators represent an expensive alternative, especially for baseload power. This has led to serious consideration of electric generating systems using locally available renewable resources, including biomass, hydro, wind, and solar energy. A project has recently been initiated in Riberalta, in the Amazonian region of Bolivia, to convert waste Brazil nut shells and sawmill residues to electricity. Working in tandem with diesel generators, the biomass-fired plant will produce base-load power in an integrated system that will be able to provide reliable and affordable electricity to the city. The project will allow the local rural electric cooperative to lower the price of electricity by nearly forty percent, enable the local Brazil nut industry to increase its level of mechanization, and reduce the environmental impacts of dumping waste shells around the city and in an adjacent river. The project is representative of others that will be funded in the future by NRECA/AID.

    For sound studies, the publication of a 593-page handbook, not to mention the establishment of at least one society - the European Sound Studies Association - might seem to signify the emergence of a new academic discipline. Certainly, the books under consideration here, alongside many others, testify to an intensification of concern with the aural dimensions of culture. Some of this work comes from HPS and STS, some from musicology and cultural studies. But all of it should concern members of our disciplines, as it represents a long-overdue foregrounding of the aural in how we think about the intersections of science, technology and culture.

  3. Conditioned sounds enhance visual processing.

    Directory of Open Access Journals (Sweden)

    Fabrizio Leo

    Full Text Available This psychophysics study investigated whether prior auditory conditioning influences how a sound interacts with visual perception. In the conditioning phase, subjects were presented with three pure tones ( =  conditioned stimuli, CS that were paired with positive, negative or neutral unconditioned stimuli. As unconditioned reinforcers we employed pictures (highly pleasant, unpleasant and neutral or monetary outcomes (+50 euro cents, -50 cents, 0 cents. In the subsequent visual selective attention paradigm, subjects were presented with near-threshold Gabors displayed in their left or right hemifield. Critically, the Gabors were presented in synchrony with one of the conditioned sounds. Subjects discriminated whether the Gabors were presented in their left or right hemifields. Participants determined the location more accurately when the Gabors were presented in synchrony with positive relative to neutral sounds irrespective of reinforcer type. Thus, previously rewarded relative to neutral sounds increased the bottom-up salience of the visual Gabors. Our results are the first demonstration that prior auditory conditioning is a potent mechanism to modulate the effect of sounds on visual perception.

    Context Built environment-focused interventions and policies are recommended as sustainable approaches for promoting physical activity. Physical activity has not traditionally been considered in land use and transportation decision making. Effective collaboration with non-public health partners requires knowledge of their perceived barriers to consideration of physical activity in decision making. Objective This study aimed to 1) identify barriers to the consideration of physical activity in community design and planning decisions among municipal decision makers and 2) explore differences in these barriers among a wide range of job functions and departments in a geographically diverse sample. Design A web-based survey was conducted among municipal officials in 94 cities and towns with populations of at least 50,000 residents in eight states. Participants 453 municipal officials from public health, planning, transportation/public works, community and economic development, parks and recreation, city management, and municipal legislatures responded to the survey. Main Outcome Measures Five barriers to consideration of physical activity in community design and layout were assessed. Results The most common barriers included lack of political will (23.5%), limited staff (20.4%) and lack of collaboration across municipal departments (16.2%). Fewer participants reported opposition from the business community or residents as barriers. Compared to other professionals, public health department personnel were more likely to report the barriers of limited staff and lack of collaboration across municipal departments. They were also more likely to report lack of political will compared to city managers or mayors and municipal legislators. Conclusions Barriers to increasing consideration of physical activity in decision making about community design and layout are encouragingly low. Implications for public health practice include the need to strategically increase political will

    It is known that fluoridation has a contextual effect on oral health socioeconomic inequalities, but broad public policies have not been investigated. Thus, the aim of this study was to determine the effects of municipal public policies on oral health across different social strata. This was a cross-sectional study with 7328 12-year-old children and 5445 15-19-year-old adolescents from 177 Brazilian municipalities. Information at municipal level was collated for dental services, educational services, sanitation and water fluoridation. The main individual-level exposure was the disposable equivalent household income. The dichotomous outcomes were as follows: untreated dental caries (≥1 tooth), missing teeth (≥1 tooth) and filled teeth (≥1 tooth). Analyses were carried out using multilevel logistic regression. Interaction terms were tested between individual-level income and policy variables. The prevalence of untreated dental caries, missing and filled teeth was 47.0%, 15.1% and 47.5%, respectively. There was no significant interaction between income and policy indicators. Individuals living in municipalities with no water fluoridation had 1.42 (95% CI: 1.08-1.86) higher odds of having untreated dental caries; the odds ratio (OR) for those in municipalities with less education policies was 1.36 (95% CI: 1.07-1.73); those in municipalities with less sanitation had OR = 1.05 (95% CI: 0.78-1.40); and those in municipalities with less dental care had OR = 1.36 (95% CI: 1.02-1.80). Fluoridation and policies about sanitation, education and dental care were similarly associated with oral health in different social strata. Other policies on social and economic fields may be further explored. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Built environment-focused interventions and policies are recommended as sustainable approaches for promoting physical activity. Physical activity has not traditionally been considered in land use and transportation decision making. Effective collaboration with non-public health partners requires knowledge of their perceived barriers to such consideration. This analysis sought to (a) establish prevalence estimates of selected barriers to the consideration of physical activity in community design and layout decisions and (b) describe how barrier reporting by public health officials differs from other municipal officials among a wide range of job functions and departments in a geographically diverse sample. A Web-based survey was conducted among municipal officials in 94 cities and towns with populations of at least 50 000 residents in 8 states. A total of 453 municipal officials from public health, planning, transportation/public works, community and economic development, parks and recreation, city management, and municipal legislatures in 83 cities and towns responded to the survey. Five barriers to consideration of physical activity in community design and layout were assessed. The most common barriers included lack of political will (23.5%), limited staff (20.4%), and lack of collaboration across municipal departments (16.2%). Fewer participants reported opposition from the business community or residents as barriers.

  8. Valuation Bases and Accounting System Entries in Financial Analysis of the Municipal Real Property

    Directory of Open Access Journals (Sweden)

    Daniela Feschiyan

    2013-08-01

    Full Text Available The paper introduces a conceptual framework for an accounting of the municipal real property, and defines a respective system of indicators. The development of this framework is seen as an important prerequisite for the efficient property management. It aims to overcome the lack or poor accessibility of the information, and thus to ensure the successful municipal real property management in a strategic context. The developing of the applied approach implies that accounting indicators are divided into three main groups – values, revenues, and costs. Beside the above mentioned classification, the municipal revenues and costs are classified also as existing and proposed. The existing indicators are defined by International Accounting Standards in public sector, and some of them are considered as being appropriate for the inclusion in the financial analysis as accounting system entries. The proposed indicators are perceived as appropriate to carry out a detailed analysis of the municipal property at a lower level of desegregations. The first two paragraphs explain the main bases for the municipal property valuation - historical cost, current price, market value, present value, with a special emphasis on the use of the historical value, and the types of valuation respectively. The next three paragraphs are concentrated mainly on the accounting indicators for the municipal property assessment. The sixth paragraph represents several major accounting bases - an accounting value, a carrying value, a market value, an accumulated depreciation, revenues from the sale of assets and services, costs by economic elements, revenues from future periods and costs for future periods, and revenues from other events and costs for other events. The seventh section presents a brief comparative analysis of accounting systems of 6 municipalities in South-Eastern Europe and the last paragraph highlights the identified “good practices”.

    2011-01-01

    Photogates are probably the most commonly used electronic instruments to aid experiments in the field of mechanics. Although they are offered by many manufacturers, they can be too expensive to be widely used in all classrooms, in multiple experiments or even at home experimentation. Today all computers have a sound card - an interface for analogue signals. It is possible to make very simple yet highly accurate photogates for cents, while much more sophisticated solutions are also available at a still very low cost. In our paper we show several experimentally tested ways of implementing sound card photogates in detail, and we also provide full-featured, free, open-source photogate software as a much more efficient experimentation tool than the usually used sound recording programs. Further information is provided on a dedicated web page, www.noise.physx.u-szeged.hu/edudev.

    2016-08-01

    Full Text Available The article scientifically substantiates the insights on the theory and the practice of using microchromatic in modern musical art, defines compositional and expressive possibilities of microtonal system in the works of composers of XXI century. It justifies the author's interpretation of the concept of “ultrahromatizm”, as a principle of musical thinking, which is connected with the sound space conception as the space-time continuum. The paper identifies the correlation of the notions “microchromatism” and “ultrahromatizm”. If microchromosome is understood, first and for most, as the technique of dividing the sound into microparticles, ultrahromatizm is interpreted as the principle of musical and artistic consciousness, as the musical focus of consciousness on the formation of the specific model of sound meditation and understanding of the world.

    Vieira, Victor H Argentino de Morais; Matheus, Dácio R

    2018-01-01

    Social factors have not been sufficiently explored in municipal solid waste management studies. Latin America has produced even fewer studies with this approach; technical and economic investigations have prevailed. We explored the impacts of socioeconomic factors on municipal solid waste generation in Greater Sao Paulo, which includes 39 municipalities. We investigated the relations between municipal solid waste generation and social factors by Pearson's correlation coefficient. The Student's t-test (at p ← 0.01) proved significance, and further regression analysis was performed with significant factors. We considered 10 socioeconomic factors: population, rural population, density, life expectancy, education (secondary, high and undergraduate level), income per capita, inequality and human development. A later multicollinearity analysis resulted in the determination of inequality (r p = 0.625) and income per capita (r p = 0.607) as major drivers. The results showed the relevance of considering social aspects in municipal solid waste management and isolated inequality as an important factor in planning. Inequality must be used as a complementary factor to income, rather than being used exclusively. Inequality may explain differences of waste generation between areas with similar incomes because of consumption patterns. Therefore, unequal realities demand unequal measures to avoid exacerbation, for example, pay-as-you-throw policies instead of uniform fees. Unequal realities also highlight the importance of tiering policies beyond the waste sector, such as sustainable consumption.

    This study fills demand for data on access and use of information and communication technologies (ICT) in the Brazilian legal Amazon, a region of localities with identical economic, political, and social problems. We use the 2010 Brazilian Demographic Census to compile data on urban and rural households (i) with computers and Internet access, (ii) with mobile phones, and (iii) with fixed phones. To compare the concentration of access to ICT in the municipalities of the Brazilian Amazon with other regions of Brazil, we use a concentration index to quantify the concentration of households in the following classes: with computers and Internet access, with mobile phones, with fixed phones, and no access. These data are analyzed along with municipal indicators on income, education, electricity, and population size. The results show that for urban households, the average concentration in the municipalities of the Amazon for computers and Internet access and for fixed phones is lower than in other regions of the country; meanwhile, that for no access and mobile phones is higher than in any other region. For rural households, the average concentration in the municipalities of the Amazon for computers and Internet access, mobile phones, and fixed phones is lower than in any other region of the country; meanwhile, that for no access is higher than in any other region. In addition, the study shows that education and income are determinants of inequality in accessing ICT in Brazilian municipalities and that the existence of electricity in rural households is directly associated with the ownership of ICT resources.

  13. Market forces in municipal and industrial waste-to-energy

    The market for municipal and industrial waste-to-energy can be characterized simply as currently soft with continued excellent long-term prospects. But as in all markets large and small, niche opportunities exist now which can be profitable with proper definition and strategy. Economics of several projects have proven marginal, cost overruns are common, and revenue projections are sometimes overstates. Also contributing to poorer economics of late are lower prices for the electric power produced from these plants. New environmental restrictions are adding 10-15% to the capital costs of a given project. On the industrial front, the strength of waste-fuel firing continues to be evident for independent power production. Important fuel-niche markets have sprung up over the last decade including petroleum coke, coal-mining wastes, hospital or redbag wastes, biomass, used tires, and so on. Another fuel niche is hazardous waste incineration. In the municipal arena, realism has not yet hit the recycling and source reduction enthusiasts. Only 25-35% recycling is considered practical by experts. There are also limits to how often material can be recycled. Finally, in spite of the best efforts of the population to control the amount of refuse generated and to recycle that which is, population and economic growth may overtake any new sense of environmental responsibility. And, yes, the additional refuse still has to go somewhere exclamation point The best somewhere option continues to be a waste-to-energy plant. Current market opportunities and two other market forces (international activities and the role of US utilities) are discussed

    Based on the Huygens-Fresnel principle, a metasurface structure is designed to generate a sound vortex beam in airborne environment. The metasurface is constructed by a thin planar plate perforated with a circular array of deep subwavelength resonators with desired phase and amplitude responses. The metasurface approach in making sound vortices is validated well by full-wave simulations and experimental measurements. Potential applications of such artificial spiral beams can be anticipated, as exemplified experimentally by the torque effect exerting on an absorbing disk.

  18. Sound symbolism: the role of word sound in meaning.

    Svantesson, Jan-Olof

    2017-09-01

    The question whether there is a natural connection between sound and meaning or if they are related only by convention has been debated since antiquity. In linguistics, it is usually taken for granted that 'the linguistic sign is arbitrary,' and exceptions like onomatopoeia have been regarded as marginal phenomena. However, it is becoming more and more clear that motivated relations between sound and meaning are more common and important than has been thought. There is now a large and rapidly growing literature on subjects as ideophones (or expressives), words that describe how a speaker perceives a situation with the senses, and phonaesthemes, units like English gl-, which occur in many words that share a meaning component (in this case 'light': gleam, glitter, etc.). Furthermore, psychological experiments have shown that sound symbolism in one language can be understood by speakers of other languages, suggesting that some kinds of sound symbolism are universal.

    The increasing generation of municipal solid waste (MSW) is a major problem particularly for large urban areas with insufficient landfill capacities and inefficient waste management systems. Several options associated to the supply chain for implementing a MSW management system are available, however to determine the optimal solution several technical, economic, environmental and social aspects must be considered. Therefore, this paper proposes a mathematical programming model for the optimal planning of the supply chain associated to the MSW management system to maximize the economic benefit while accounting for technical and environmental issues. The optimization model simultaneously selects the processing technologies and their location, the distribution of wastes from cities as well as the distribution of products to markets. The problem was formulated as a multi-objective mixed-integer linear programing problem to maximize the profit of the supply chain and the amount of recycled wastes, where the results are showed through Pareto curves that tradeoff economic and environmental aspects. The proposed approach is applied to a case study for the west-central part of Mexico to consider the integration of MSW from several cities to yield useful products. The results show that an integrated utilization of MSW can provide economic, environmental and social benefits. Copyright © 2013 Elsevier Ltd. All rights reserved.

    This research investigates the embodied energy associated with water use. A geographic information system (GIS) was tested using data from Loudoun County, Virginia. The objective of this study is to estimate the embodied energy and carbon emission levels associated with water service at a geographical location and to improve for sustainability planning. Factors that affect the carbon footprint were investigated and the use of a GIS based model as a sustainability planning framework was evaluated. The carbon footprint metric is a useful tool for prediction and measurement of a system's sustainable performance over its expected life cycle. Two metrics were calculated: tons of carbon dioxide per year to represent the contribution to global warming and watt-hrs per gallon to show the embodied energy associated with water consumption. The water delivery to the building, removal of wastewater from the building and associated treatment of water and wastewater create a sizable carbon footprint; often the energy attributed to this water service is the greatest end use of electrical energy. The embodied energy in water depends on topographical characteristics of the area's local water supply, the efficiency of the treatment systems, and the efficiency of the pumping stations. The questions answered by this research are: What is the impact of demand side sustainable water practices on the embodied energy as represented by a comprehensive carbon footprint? What are the major energy consuming elements attributed to the system? What is a viable and visually identifiable tool to estimate the carbon footprint attributed to those Greenhouse Gas (GHG) producing elements? What is the embodied energy and emission associated with water use delivered to a building? Benefits to be derived from a standardized GIS applied carbon footprint estimation approach include: (1) Improved environmental and economic information for the developers, water and wastewater processing and municipal

    2008-01-01

    Full Text Available Planning of tourism development and its spatial disposition in Europe and world today are an important segment of the overall economic development. Having in mind its important economic and social functions, as well as its capability to intensify its other economic branches (agricultural and economic potentials, services of various types, transport and other in a certain territory, it is necessary to realize a precise valorization of tourist values in the spatial plan of municipality and to conclude at what point and at which places the tourism can represent on of development components of the entire economy of the territory to be planed. The example of the spatial plan of Subotica and main guidelines, concept and planning priorities which can be expected in the forthcoming period are presented in this paper. It is without any doubt that the municipality of Subotica with its geostrategic position, the proximity of the EU and important natural and cultural tourist potentials is a suitable space for application of contemporary principles of the tourism development planning and their correlation with other segments of integral development for the whole municipality.

  6. Vocal Imitations of Non-Vocal Sounds

    2016-01-01

    Imitative behaviors are widespread in humans, in particular whenever two persons communicate and interact. Several tokens of spoken languages (onomatopoeias, ideophones, and phonesthemes) also display different degrees of iconicity between the sound of a word and what it refers to. Thus, it probably comes at no surprise that human speakers use a lot of imitative vocalizations and gestures when they communicate about sounds, as sounds are notably difficult to describe. What is more surprising is that vocal imitations of non-vocal everyday sounds (e.g. the sound of a car passing by) are in practice very effective: listeners identify sounds better with vocal imitations than with verbal descriptions, despite the fact that vocal imitations are inaccurate reproductions of a sound created by a particular mechanical system (e.g. a car driving by) through a different system (the voice apparatus). The present study investigated the semantic representations evoked by vocal imitations of sounds by experimentally quantifying how well listeners could match sounds to category labels. The experiment used three different types of sounds: recordings of easily identifiable sounds (sounds of human actions and manufactured products), human vocal imitations, and computational “auditory sketches” (created by algorithmic computations). The results show that performance with the best vocal imitations was similar to the best auditory sketches for most categories of sounds, and even to the referent sounds themselves in some cases. More detailed analyses showed that the acoustic distance between a vocal imitation and a referent sound is not sufficient to account for such performance. Analyses suggested that instead of trying to reproduce the referent sound as accurately as vocally possible, vocal imitations focus on a few important features, which depend on each particular sound category. These results offer perspectives for understanding how human listeners store and access long

  7. Municipal consultation key to understanding haul road maintenance agreements for Saskatchewan rural municipalities

    1998-01-01

    Current municipal perspectives regarding the oil and gas industry in Saskatchewan were described. Municipal jurisdiction and authority regarding road development and heavy haul road maintenance agreements were defined. Based on actual work experience, collaborative working relationships between the oil and gas industry and the municipal sector is well worth some industry time and effort since it will result in cost savings for the industry. In general, rural municipalities receive very limited tax benefits to recapture the costs of road reconstruction and maintenance caused by heavy industry traffic. Road servicing costs can be recaptured only if companies respect the weight limits, hauling regulations and road bans. On the whole, municipalities in Saskatchewan are favourably disposed towards the oil and gas industry, and have done well in the past to accommodate industry's needs. It is not unreasonable therefore to expect that industry show sensitivity to the impact of its activities on the local municipality, and does its level best to be on good terms with the municipalities through early two-way communication. Text of some relevant acts of the Legislature respecting the powers and authorities of rural municipalities are appended

    Visual information is extremely important to generate internal spatial representations. In the auditory modality, the absence of visual cues during early infancy does not preclude the development of some spatial strategies. However, specific spatial abilities might result impaired. In the current study, we investigated the effect of early visual deprivation on the ability to localize static and moving auditory stimuli by comparing sighted and early blind individuals’ performance in different spatial tasks. We also examined perceptual stability in the two groups of participants by matching localization accuracy in a static and a dynamic head condition that involved rotational head movements. Sighted participants accurately localized static and moving sounds. Their localization ability remained unchanged after rotational movements of the head. Conversely, blind participants showed a leftward bias during the localization of static sounds and a little bias for moving sounds. Moreover, head movements induced a significant bias in the direction of head motion during the localization of moving sounds. These results suggest that internal spatial representations might be body-centered in blind individuals and that in sighted people the availability of visual cues during early infancy may affect sensory-motor interactions.

    The amount of solid waste generated in developing countries is rising from time to time due to economic growth, change in consumer behavior and lifestyles of people. But it is hard to manage and handle the increase of solid waste with existing waste management infrastructure. Thus, the management system of solid waste is very poor and become a serious problem. The main purpose of this study is to quantify the volume of solid waste generated and investigate factors affecting generation and disposal of wastes in the study area. The result of this study indicated that total waste generated from households was about 97.092kg/day.Furthermore, the study reveals that the solid waste generation rate of the town is 0.261kg/person/day.About 57.5% of solid waste is properly disposed of to landfill site whereas the remaining 42.5% is illegally dumped at the roadsides and open fields. Implication Statement Nowadays, in developing countries there is high concentration of people in urban areas and cause for the generation of enormous concentration of municipal waste in urban areas. Therefore this finding will be important for various policy makers and town planners. It may also serve as a benchmark for the municipal authorities of the town for whom the problem is still invisible and negligible and can push environmental protection authorities to reexamine the implementation of their policies and strategies with regard to the broader issues of human and environmental health condition of town dwellers.

    Dumping of municipal waste to disposal areas has caused environmental problems, and this has led to more sophisticated disposal systems and high prices. That and a general demand to reduce the quantity of waste require new solutions, and a question has been arisen whether combustion could be used to treat waste. This project is concentrating to bum waste in a small-scale power plant. The background is one 10-MW pilot in Tampere city based on smelting furnace and a 0.3-MW pyrolyse furnace. The results of these from the viewpoint of operation and effluent were satisfactory and the burning process used is in line with the latest regulations. The second aspect is the economy of waste handling. The minipower plant is designed for reasonable small municipalities, abt 20 000 inhabitants or 1 - 20 MW heat input. According to several feasibility studies this method is the cheapest way to handle waste. A local heat demand is used to support the economy. The prices of products, heat and power, and cost are of the same level as the market prices. Thus, we expect a economical and environmentally safe operation with the minipower plant and it will also give a hint to solve a higher capacity demand of one unit. (orig.)

    The article has for objective to demonstrate the positive and negative impacts of the exploration of petroleum in the Municipal districts, giving emphasis to the destination of the resources obtained by the referred royalties in those federal entities. It is known that the economical activities linked directly to the industry of the petroleum are temporary. The announcement of the perspective of current economical activities of the implantation of that industry creates the expectation of generation of offer of abundant labor. The phenomenon raises migratory demographic pressure uncontrollable on the production areas and neighbors. The migration generates overloads of public services and lack of community equipment, already insufficient to assist to the existent demands. Besides, it happens environmental degradation and the consequent reduction of the tourist activities in the municipal districts that stand out for their natural beauties.

    Full Text Available One of the most important development banks which finances private initiatives in the Central and Eastern Europe countries is the European Bank for Reconstruction and Development (EBRD. EBRD as international financial institution plays a very important role in the development of many sectors such as agribusiness, energy efficiency, financial institutions, manufacturing, municipal and environmental infrastructure, natural resources, power and energy, property and tourism, telecommunications, information technology and media, transport. Its objectives aim to promote transition to market economies by investing mainly in the private sector, to mobilize significant foreign direct investment, to support privatization, restructuring and better municipal services to improve people’s lives and to encourage environmentally sound and sustainable development. The present scientific article focuses on the last objective respectively the bank commitment to promote environmentally sound and sustainable development and shortly presents EBRD environmental policy because EBRD, unlike other development banks, has strong and imperative regulations regarding this issue. This is why all the EBRD potential beneficiaries must prove that their projects are environmentally sound.

    1978-05-01

    Sediment cores from Narragansett Bay and Rhode Island Sound have been analyzed for petroleum hydrocarbons and compared with a relatively unpolluted sediment core from the Gulf of Maine. The sediments were analyzed for unbound hydrocarbons, hydrocarbons bound or closely associated with humic substances, and residual hydrocarbons bound or closely associated with the clay mineral or kerogen matrix. Results indicated that in general 90-100% of the hydrocarbons were in the unbound form and could be easily extracted with organic solvents. The petroleum hydrocarbons decreased with depth at all stations. Biogenic hydrocarbons (nC/sub 25/, nC/sub 27/, nC/sub 29/, and nC/sub 31/) made up an increasingly greater percentage of the total with increasing depth. The hydrocarbons in the Narragansett Bay sediments and near surface Rhode Island Sound sediments strongly resembled the hydrocarbons previously reported for the Providence River and upper Narragansett Bay. These petroleum-like hydrocarbons were shown to be largely introduced to the river and bay through chronic inputs from a municipal wastewater treatment plant. These hydrocarbons then undergo sedimentation throughout the entire bay and into Rhode Island Sound. Preliminary calculations indicate that over 0.2 million t (tonne) of petroleum hydrocarbons may be transported to the marine environment annually from municipal treatment plants. Most of these hydrocarbons appear to accumulate in estuarine and coastal sediments.

    Municipal solid waste management (MSWM) in China warrants particular attention as China has become the largest MSW generator in the world and the total amount of MSW it produces continues to increase. In recent years, central and local governments have made great efforts to improve MSWM in China. New regulations and policies have been issued, urban infrastructure has been improved, and commercialization and international cooperation have been encouraged. Considering these developments, an overview is necessary to analyze the current state as well as new opportunities and challenges regarding MSWM in China. This paper shows that since the late 1990s, the amount of MSW collected has been largely decoupled from economic growth and incineration has become an increasingly widespread treatment method for MSW. We identify and discuss four major challenges and barriers related to China's MSWM, and propose an integrated management framework to improve the overall eco-efficiency of MSWM.

    Rapid economic development and population growth, inadequate infrastructure and expertise, and land scarcity make the management of municipal solid waste become one of Malaysia's most critical environmental issues. The study is aimed at evaluating the generation, characteristics, and management of solid waste in Malaysia based on published information. In general, the per capita generation rate is about 0.5-0.8 kg/person/day in which domestic waste is the primary source. Currently, solid waste is managed by the Ministry of Housing and Local Government, with the participation of the private sector. A new institutional and legislation framework has been structured with the objectives to establish a holistic, integrated, and cost-effective solid waste management system, with an emphasis on environmental protection and public health. Therefore, the hierarchy of solid waste management has given the highest priority to source reduction through 3R, intermediate treatment and final disposal.

    Data for the composition of municipal solid waste is a critical basis for any assessment of waste technologies and waste management systems. The detailed quantification of waste fractions is absolutely needed for a better technological development of waste treatment. The current waste composition...... comparability to characterize municipal solid waste. This methodology was applied to residual waste collected from 1,442 households in three municipalities in Denmark. The main fractions contributing to the residual household waste were food waste and miscellaneous waste. Statistical analysis suggested...... of standardised and commonly accepted waste characterization methodologies, various approaches have been reported in literature. This limits both comparability and applicability of the results. The purpose of this study was to introduce a consistent methodology that reduces uncertainties and ensures data...

    Full Text Available The globalization is breaking-down the idea of national state, which was the base for the development of economic theory which is dominant today. Global economic crisis puts emphasis on limited possibilities of national governments in solving economic problems and general problems of society. Does it also mean that globalization and global economic crisis points out the need to think about new economic theory and new understanding of economics? In this paper I will argue that globalization reveals the need to change dominant economic paradigm - from traditional economic theory (mainstream with macroeconomic stability as the goal of economic policy, to the “quantum economics“, which is based on “economic quantum” and immanent to the increase of wealth (material and non-material of every individual in society and promoting set of values immanent to the wealth increase as the goal of economic policy. Practically the question is how we can use global market for our development!

    In recent years, in Russia both official and media discourses have emphasized the need to modernize, optimize and reform the institutions of public and municipal administration as basic means of socio-economic and political development of the country. Unfortunately, quite often different organizational forms within the system of social management encounter not only institutional or objective obstacles, but also subjective problems determined by the “quality” of human resources. For decades, t...

    Many countries in the European Union (EU) have very developed waste management systems. Some of its members have managed to reduce their landfilled waste to values close to zero during the last decade. Thus, European Union legislation is very stringent regarding waste management for their members and candidate countries, too. This raises the following questions: Is it possible for developing and developed countries to comply with the European Union waste legislation, and under what conditions? How did waste management develop in relation to the economic development in the countries of the European Union? The correlation between waste management practices and economic development was analysed for 27 of the European Union Member States for the time period between 1995 and 2007. In addition, a regression analysis was performed to estimate landfilling of waste in relation to gross domestic product for every country. The results showed a strong correlation between the waste management variables and the gross domestic product of the EU27 members. The definition of the municipal solid waste management development phases followed a closer analysis of the relation between gross domestic product and landfilled waste. The municipal solid waste management phases are characterised by high landfilling rates at low gross domestic product levels, and landfilling rates near zero at high gross domestic product levels. Hence the results emphasize the importance of wider understanding of what is required for developing countries to comply with the European Union initiatives, and highlight the importance of allowing developing countries to make their own paths of waste management development. © The Author(s) 2015.

    Full Text Available Waste removal (collection and landfilling in the Republic of Croatia is the responsibility of the municipalities and local governments in 21 administrative units (counties. They entrust the respective economic activity to 208 private and public companies specialized in waste collection and treatment. Organised waste collection affects 99 % of the population. The mixed waste from households and enterprises is at various frequencies collected at the door (kerbside collection and transported by truck to a landfill, or processing plant. This article aims to estimate fuel consumption and fuel-related airborne emissions from the collection of mixed municipal waste in Croatia in 2013. The input data and emission results are shown for Croatia and each Croatian county, in total, and relative to the number of inhabitants and mass of collected waste. Annual consumption of diesel for the collection of mixed waste is estimated at 10.6 million litres. At the county level, fuel consumption ranges from 87 thousand litres to 2.2 million litres, on average 504 thousand litres per county. Total emission of CO2 is estimated at 28 000 t, which at county level ranges from 231 to 5711 t. Relative emission ranges from 3.3 to 13 kg CO2 per capita (average 6.6 kg per capita, or 8.6–28.1 kg t−1 of municipal waste (average 17 kg CO2 per ton of municipal waste. The average values of CO2 emission from MSW collection that should also be the target values are 7–9 kg for mixed waste, and 8–15 kg CO2 for separate waste streams. Apart from CO2 emission, this research estimates emission of other, diesel combustion related compounds, such as NOx, CO, lubricant related CO2, NMVOC, PM, f-BC, N2O, SO2, NH3, Pb, ID[1,2,3-cd]P, B[k]F, B[b]F, B[a]P, as well as total distance of transport.

    While much attention has been devoted to analyzing how the institutional framework and entrepreneurship impact growth, how economic policy and institutional design affect entrepreneurship appears to be much less analyzed. We try to explain cross-country differences in the level of entrepreneurship...... by differences in economic policy and institutional design. Specifically, we use the measures of economic freedom to ask which elements of economic policy making and the institutional framework that are responsible for the supply of entrepreneurship (our data on entrepreneurship are derived from the Global...... Entrepreneurship Monitor). The combination of these two datasets is unique in the literature. We find that the size of government is negatively correlated with entrepreneurial activity but that sound money is positively correlated with entrepreneurial activity. Other measures of economic freedom...

    Following a planktonic dispersal period of days to months, the larvae of benthic marine organisms must locate suitable seafloor habitat in which to settle and metamorphose. For animals that are sessile or sedentary as adults, settlement onto substrates that are adequate for survival and reproduction is particularly critical, yet represents a challenge since patchily distributed settlement sites may be difficult to find along a coast or within an estuary. Recent studies have demonstrated that the underwater soundscape, the distinct sounds that emanate from habitats and contain information about their biological and physical characteristics, may serve as broad-scale environmental cue for marine larvae to find satisfactory settlement sites. Here, we contrast the acoustic characteristics of oyster reef and off-reef soft bottoms, and investigate the effect of habitat-associated estuarine sound on the settlement patterns of an economically and ecologically important reef-building bivalve, the Eastern oyster (Crassostrea virginica). Subtidal oyster reefs in coastal North Carolina, USA show distinct acoustic signatures compared to adjacent off-reef soft bottom habitats, characterized by consistently higher levels of sound in the 1.5-20 kHz range. Manipulative laboratory playback experiments found increased settlement in larval oyster cultures exposed to oyster reef sound compared to unstructured soft bottom sound or no sound treatments. In field experiments, ambient reef sound produced higher levels of oyster settlement in larval cultures than did off-reef sound treatments. The results suggest that oyster larvae have the ability to respond to sounds indicative of optimal settlement sites, and this is the first evidence that habitat-related differences in estuarine sounds influence the settlement of a mollusk. Habitat-specific sound characteristics may represent an important settlement and habitat selection cue for estuarine invertebrates and could play a role in driving
