    1991-01-01

    This paper reports on wireline logging problems which have plagued the reservoir section of development wells in Welton oil field in the East Midlands area of England. And resulting incomplete or poor-quality logging data spurred a look at ways of improving hole conditions. Oil-based muds often are seen as the ideal solution, but they are expensive. Their use also commits the operator to additional costs from safeguarding personnel and limiting environmental impact. Such expense was initiated to develop a cheaper, more environmentally friendly, water-based alternative. A wide-ranging review was carried out to determine the most cost-effective options to obtain reservoir information. This included an examination of lithology, casing design, bit selection, hydraulics, logging requirements and techniques, and development of a suitable water-based mud. This holistic approach was seen as the most effective method of avoiding use of oil-based mud. After successful experimentation, a water-based mud was used in subsequent wells at Welton. A high-salt mud system and the drilling principles discussed here produced significant improvement in hole conditions. Application of a holistic approach led to many operational improvements. For instance, the casing shoe was deepened to case off the most troublesome zone in the local Edlington formation. There also was a better awareness of alternative logging techniques, the commercial factors that influenced their use and their operational and technical limitations. Logging problems were reduced but not eliminated. Where there were problems, application of improved techniques minimized their impact. Last, but not least, there was an unexpected spin-off in that the bit chosen to reduce hole erosion also reduced the time taken to drill the section

    The alternate wetting and drying (AWD) technology for rice production does not only save 15-30% of irrigation water, it also reduces methane emissions by up to 70%. AWD is defined by periodic drying and re-flooding of a rice field. Due to its high mitigation potential and its simplicity to execute this practice AWD has gained a lot of attention in recent years. The Climate and Clean Air Coalition (CCAC) has put AWD high on its agenda and funds a project to guide implementation of this technology in Vietnam, Bangladesh and Colombia. One crucial activity is a biophysical suitability assessment for AWD in the three countries. For this, we analyzed rainfall and soil data as well as potential evapotranspiration to assess if the water balance allows practicing AWD or if precipitation is too high for rice fields to fall dry. In my talk I will outline key factors for a successful large-scale implementation of AWD with a focus on the biophysical suitability assessment. The seasonal suitability maps that we generated highlight priority areas for AWD implementation and guide policy makers to informed decisions about meaningful investments in infrastructure and extension work.

    Full Text Available This study reviewed and analyzed the specific practices, implementation effects and applicable conditions of fertilizer reduction policies in the EU, US and Japan, explored the common laws and general conditions in the formulation of environmental orientation, and pro vided feasible policy recommendations for the formulation of fertilizer reduction policies in China. This study showed that fertilizer reduction policies in each country had their own advantages and disadvantages, and the applicable conditions were different. The EU's command and control policy was applicable to the situation of less farm households and the same agricultural planting type or farm type. The economic in centive policy in the US was applicable to the situation of more farm households, relatively perfect agricultural market system and sensitive price formation mechanism, while the public participation policy in Japan was applicable to regions with more relevant agricultural groups and strong economy. China should learn from each of these policies and make a comprehensive choice in the formulation of fertilizer reduc tion policies. Therefore, China should proceed from improving the agricultural price mechanism and the pollution-free agricultural products certification system as well as encouraging and supporting the development of large scale production units, and then promote the adoption of environmentally friendly technology through the guidance of market mechanism, ensure the effective implementation of environmental stan dards through farmers' integration and improve farmers' environmental awareness through propaganda guidance, so as to ensure the effective implementation of different types(command and control policy, economic incentive policy and public participation policyof fertilizer reduc tion policies.

    Aw, M.; Wagner, M.R.

    1993-01-01

    Saline pulp and paper wastewater produced by Stone Container Corporation in Snowflake, Arizona was used to irrigate 32 different species/genotypes/hybrids of woody plants to test their suitability as an alternative treatment to the current wastewater disposal method. Suitability was measured in terms of survival and height growth. Among the 32 species, six were found to be a very good choice for wastewater treatment and biomass production. Their suitability is further justified by the fact that some have salt tolerance and others fix nitrogen. These species are Tamarix ramosissima, Atriplex canescens, Robinia pseudoacacia, Eleagnus angustifoliz, Ulmus pumila, and Populus deltoides x Populus nigra. Three other species are possible candidates. These include Caragana arborescens, Gleditsia triacanthos and Populus deltoides var. siouxland. In general, conifers performed poorly because of the harsh environment and other silvicultural problems

    Because of worldwide growing concerns about global climate change, great interest has been expressed in the potential of alternative climate policies to reduce global carbon emissions. In this paper, we compare cross-country implications of alternative climate policies, including unilateral and multilateral climate policies. Our main findings are as follows. Firstly, there are large differences in cross-country effects of alternative unilateral climate policies, when the same given carbon emission reductions are achieved in each abating country respectively. Meanwhile, cross-border externalities undermine efficiency of unilateral climate policies. Secondly, there are significant differences in cross-country implications of alternative multilateral climate policies, when the same global emission reductions are allocated in several different ways among abating countries. Thirdly, it is difficult to reach a stable global climate treaty, since any abating country has the incentive to argue for small carbon emission reductions. Finally, multilateral climate policies can reduce the negative impacts of cross-border externalities, but cannot cure all cross-border externalities. Looking ahead, it will be a great policy challenge for the world to reduce carbon emissions in a cost-effective way. - highlights: • We compare impacts of unilateral climate policies across countries. • We compare effects of alternative multilateral climate policies. • We explore whether cross-border externalities disappear under multilateral climate policies

    The economy of climate policy is characterized by notions as cost-benefit analysis, optimal policy and optimal timing. It is argued that the use of such notions reflects an unjustified optimism with respect to the contribution of economic science to the discussion on climate policy. The complexity of the biosphere and the uncertainty about climatic change, as well as their socio-economic consequences, are extensive. Another economic approach of the climate problem is suggested, based on complexity and historical justice. 12 refs [nl

    1997-01-01

    Accessible reports on risk assessment of interim spent nuclear fuel storage facilities presume that only releases of radioactive substances represent undesired consequences. However, only certain part of the undesired consequences is represented by them. Many other events are connected with safety and are able to cause losses to the operating company. The following two presumptions are pronounced based on this. 1. Any event causing a disturbance of a safety function of the storage facility is an incident event. 2. Any disturbance of a safety function is an undesired consequence. If the facility safety functions are identified and if the severity of their disturbances is quantified, then it is possible to combine consequence severity quantifications and event frequencies into a risk measure. Construction and application of such a risk measure is described in this paper. The measure is shown to be a tool suitable for comparison of interim storage technology design alternatives. (author)

    Transparent glass-ceramics have shown interesting optical properties for several photonic applications. In particular, compositions based on oxide glass matrices with fluoride crystals embedded inside, known as oxyfluoride glass-ceramics, have gained increasing interest in the last few decades. Melt-quenching is still the most used method to prepare these materials but sol-gel has been indicated as a suitable alternative. Many papers have been published since the end of the 1990s, when these materials were prepared by sol-gel for the first time, thus a review of the achievements obtained so far is necessary. In the first part of this paper, a review of transparent sol-gel glass-ceramics is made focusing mainly on oxyfluoride compositions. Many interesting optical results have been obtained but very little innovation of synthesis and processing is found with respect to pioneering papers published 20 years ago. In the second part we describe the improvements in synthesis and processing obtained by the authors during the last five years. The main achievements are the preparation of oxyfluoride glass-ceramics with a much higher fluoride crystal fraction, at least double that reported up to now, and the first synthesis of NaGdF₄ glass-ceramics. Moreover, a new SiO₂ precursor was introduced in the synthesis, allowing for a reduction in the treatment temperature and favoring hydroxyl group removal. Interesting optical properties demonstrated the incorporation of dopant ions in the fluoride crystals, thus obtaining crystal-like spectra along with higher efficiencies with respect to xerogels, and hence demonstrating that these materials are a suitable alternative for photonic applications.

    Full Text Available Disposal of raw municipal wastewater or effluent of preliminary treatment into the sea and ocean is economically more accepted and technically more efficient than secondary treatment. In this method, the wastewater disposed at the bottom of the sea in some points from diffuser. Nowadays, lots of researchers select outfall as a suitable alternative treatment method for coastal cities. The goal of this paper was to introduce the outfall as a wastewater treatment method and its design criteria considering different characteristics of the sea such as salinity, density, temperature, stratification etc. In addition, stagnant sea and thermal stratification is reviewed. In this paper the latest information were reviewed. In this alternative the wastewater treated under dilution, mixing and natural conditions. Moreover, sensitive coastal point are preserved from different wastewater pollutants. Usually, there is no limitation regarding discharge of coliform, DO, BOD, and nutrient concentrations in initial mixing zoom. The parameters such as thermal stratification, salinity stratification, density stratification, marine flows influence design of outfall.

    Photodynamic therapy (PDT) outcome depends on the conditions under which it is carried out. Maintaining the tumour tissue oxygen level is important for PDT efficacy and using a low fluence rate can improve outcome. In this work we studied the response of human nasopharyngeal carcinoma tumours in murine models to hypericin-PDT carried out under low fluence and fluence rate. A drug-light interval (DLI) of 1h or 6h was used for 1h-PDT and 6h-PDT, respectively. Evan's blue test was used to assess necrosis and TUNEL staining for apoptosis. Nuclear microscopy was used to quantify elemental concentrations in tumours. Serum vascular endothelial growth factor (VEGF) levels were also determined. TUNEL results showed that 6h-PDT induced significantly more apoptosis compared to 1h-PDT (ptreatment regime is suitable for the alternative approach of multi-fraction PDT in which the tumour can be exposed to multiple PDT fractions for complete tumour response. This alternative approach might yield improved outcome.

    The exponential increase of the energy consumption has reduced the possibility to pollute air and land so much that the detrimental external effects of economic activities must be regarded in energy modelling. That means to analyse the interdependent connections between the economic system and the environment and to picture the structure of the real system on a mathematical model. To do this, System Dynamics models were developed. Beside the relevant technical variables also sociological variables such as 'public pressure' or 'lobby pressure' were regarded. So it was possible to break open the 'ceteris paribus' assumption of the constant sociological and political influences. The environmental effect of various policies to meet the energy demand were critically examined in simulation runs. It was demonstrated that the pollution of the atmosphere will decrease in the beginning of the 80ies. This is based on the implementation of a new energy technology with a lower pollution and, on the other side, on the increasing amount of pollution control. (orig.) [de

    Anthropogenic activities along streams and rivers are increasingly recognized to be a major concern for fluvial ecosystems. The management of water resources, by means of e.g. flow diversions and dams, for industrial, agricultural, water-supply, hydropower production and flood protection purposes induces significant changes to the natural streamflow regime of a river. Indeed, the river flow regime is known to be a major abiotic factor influencing fluvial ecosystems. An established approach aimed at preserving the behaviour and distribution of fluvial species relies on the definition of minimum streamflow requirements (i.e., environmental flows) downstream of dams and diversion structures. Such environmental flows are normally identified through methodologies that have an empirical nature and may not be representative of local ecological and hydraulic conditions. While the effect of imposing a minimum discharge release is easily predictable in terms of e.g. loss of hydropower production, the advantages in terms of species preferences are often poorly understood and seldom assessed. To analyze the interactions between flow releases and the behaviour and distribution of fluvial species (i.e., from periphyton, to benthic invertebrate and fish), one may use a habitat suitability curve, which is a fundamental tool capable of describing species preferences influenced by any generic environmental variable. The outcomes of a real case study applied to several Italian rivers, located in the Marche administrative district in Central Italy (∽10000km2), in which we quantitatively assess the effects of alternative environmental flow scenarios on the existing hydropower network and on two fish species that are quite abundant in the study area (i.e., Leuciscus cephalus cabeda and Barbus barbus plebejus), will be presented and discussed. The proposed analysis, which can be easily adapted to different riparian habitats and hydrological contexts, is a useful tool to guide the

    The search for alternative fuels and new fuel resources is a top priority for Turkey, as is the case in the majority of countries throughout the world. The fuel policies pursued by governmental or civil authorities are of key importance in the success of alternative fuel use, especially for widespread and efficient use. Following the 1973 petroleum crisis, many users in Turkey, especially in transportation sector, searched for alternative fuels and forms of transportation. Gasoline engines were replaced with diesel engines between the mid-1970s and mid-1980s. In addition, natural gas was introduced to the Turkish market for heating in the early 1990s. Liquid petroleum gas was put into use in the mid-1990s, and bio-diesel was introduced into the market for transportation in 2003. However, after long periods of indifference governmental action, guidance and fuel policies were so weak that they did not make sense. Entrepreneurs and users experienced great economical losses and lost confidence in future attempts to search for other possible alternatives. In the present study, we will look at the history of alternative fuel use in the recent past and investigate the alternative engine fuel potential of Turkey, as well as introduce possible future policies based on experience.

    2016-01-01

    Existing policies of household biogas projects focus mainly on supports on construction, but less consider management and maintenance, resulting in high scrap rate and waste of resources. Alternative policies must be explored to balance construction and operation. Taking the costs and benefits from a typical rural household biogas project, this paper assesses the economic performance at three different subsidy levels, i.e., no subsidy, existing standard and positive externality based standard. Furthermore three subsidy alternatives, one-time, annual and combined option are applied to the externality based standard. The results show that household biogas digesters have unsatisfactory economic performance without any subsidy and even in current subsidy policies. Environmental benefits of the digester were estimated as 2732 Chinese Yuan, significantly larger than existing subsidy standard. To keep continuous work during the 20-year lifespans of digesters, the income disparity of farmers among regions must be considered for policy application. With the increasing of labor costs, the ratio of initial subsidies must be reduced. These results provide policy implications to the future development of biogas projects in terms of both their construction and follow-up management, reuse of the abandoned digesters as well as the exploitation of other emerging renewable energy projects. - Highlights: •Cost-benefit analysis of biogas was conducted involving its positive externalities. •Current subsidy level and scheme discourages sustained biogas use. •Biogas subsidy level should be raised based on the value of positive externalities. •Regionalized subsidy system is needed to address the current inefficiency.

    Abstract Finnish agriculture is likely to undergo major changes in the near and intermediate future. The ifuture policy context can be examined at a general level by strategic scenario building. Computer-based modelling in combination with agricultural policy scenarios can in turn create a basis for the assessments of changes in environmental quality following possible changes in Finnish agriculture. The analysis of economic consequences is based on the DREMFIA model, which is applied to study effects of various agricultural policies on land use, animal production, and farmers' income. The model is suitable for an impact analysis covering an extended time span--here up to the year 2015. The changes in land use, obtained with the DREMFIA model assuming rational economic behaviour, form the basis when evaluating environmental impacts of different agricultural policies. The environmental impact assessment is performed using the field scale nutrient transport model ICECREAM. The modelled variables are nitrogen and phosphorus losses in surface runoff and percolation. In this paper the modelling strategy will be presented and highlighted using two case study catchments with varying environmental conditions and land use as an example. In addition, the paper identifies issues arising when connecting policy scenarios with impact modelling.

  15. The market and environmental effects of alternative biofuel policies

    Science.gov (United States)

    Drabik, Dusan

    This dissertation analyzes market and environmental effects of alternative U.S. and Brazilian biofuel policies. Although we focus on corn- and sugarcane-ethanol, the advanced analytical framework can easily be extended to other biofuels and biofuel feedstocks, such as biodiesel and soybean. The dissertation consists of three chapters. The first chapter develops an analytical framework to assess the market effects of a set of biofuel policies (including subsidies to feedstocks). U.S. corn-ethanol policies are used as an example to study the effects of biofuel policies on corn prices. We determine the 'no policy' ethanol price, analyze the implications for the 'no policy' corn price and resulting 'water' in the ethanol price premium due to the policy, and generalize the surprising interaction effects between mandates and tax credits to include ethanol and corn production subsidies. The effect of an ethanol price premium depends on the value of the ethanol co-product, the value of production subsidies, and how the world ethanol price is determined. U.S. corn-ethanol policies are shown to be a major reason for recent rises in corn prices. The ethanol policy-induced increase in corn prices is estimated to be 33 -- 46.5 percent in the period 2008 -- 2011. The second chapter seeks to answer the question of what caused the significant increase in ethanol, sugar, and sugarcane prices in Brazil in the period 2010/11 to 2011/12. We develop a general economic model of the Brazilian fuel-ethanol-sugar complex. Unlike biofuel mandates and tax exemptions elsewhere, Brazil's fuel-ethanol-sugar markets and fuel policies are unique in that each policy, in this setting, theoretically has an ambiguous impact on the market price of ethanol and hence on sugarcane and sugar prices. Our empirical analysis shows that there are two policies that seemingly help the ethanol industry but do otherwise in reality: a low gasoline tax and a high anhydrous tax exemption result in lower ethanol

  16. Single-Case Research Methods: History and Suitability for a Psychological Science in Need of Alternatives.

    Hurtado-Parrado, Camilo; López-López, Wilson

    2015-09-01

    This paper presents a historical and conceptual analysis of a group of research strategies known as the Single-Case Methods (SCMs). First, we present an overview of the SCMs, their history, and their major proponents. We will argue that the philosophical roots of SCMs can be found in the ideas of authors who recognized the importance of understanding both the generality and individuality of psychological functioning. Second, we will discuss the influence that the natural sciences' attitude toward measurement and experimentation has had on SCMs. Although this influence can be traced back to the early days of experimental psychology, during which incipient forms of SCMs appeared, SCMs reached full development during the subsequent advent of Behavior Analysis (BA). Third, we will show that despite the success of SCMs in BA and other (mainly applied) disciplines, these designs are currently not prominent in psychology. More importantly, they have been neglected as a possible alternative to one of the mainstream approaches in psychology, the Null Hypothesis Significance Testing (NHST), despite serious controversies about the limitations of this prevailing method. Our thesis throughout this section will be that SCMs should be considered as an alternative to NHST because many of the recommendations for improving the use of significance testing (Wilkinson & the TFSI, 1999) are main characteristics of SCMs. The paper finishes with a discussion of a number of the possible reasons why SCMs have been neglected.

  18. Policy alternatives in reforming energy utilities in developing countries

    International Nuclear Information System (INIS)

    Gabriele, Alberto

    2004-01-01

    This paper examines the policy alternatives faced by developing countries in their endeavor to preserve and develop their electricity and gas systems, two service-oriented industries which--along with oil--provide the bulk of energy supply both in developed and in developing countries. Even in very poor countries, industrially generated energy is indispensable for carrying out most economic activities. Therefore, governments traditionally recognize that the supply of gas and electricity entails a fundamental public service dimension. The Introduction presents the case for reforming of energy utilities, discusses in general terms the pros and cons of privatization, and attempts to locate the reforms in a broader historical framework in which developing countries' governments faced characterized by increasing financial hardship. Section 2 constitutes the core of the paper. It reviews the main features of gas and power sector reforms in the developing world and analyzes specifically the cases of five semi-industrialized countries in Latin America and Asia. Section 3 (Concluding remarks) briefly evaluates the country experiences reviewed above and indicates a few policy lessons which can be learnt from them. The main conclusion is that, in a long-run development perspective, full-scale privatization of gas and power sectors in developing countries entails significant risks, and therefore a flexible policy approach is preferable to a rigid commitment to extensive liberalization

    Diethyl ether (ether) had been widely used in Japan for anesthesia, despite its explosive properties and toxicity to both humans and animals. We also had used ether as an anesthetic for euthanizing rats for research in the Toxicogenomics Project (TGP). Because the use of ether for these purposes will likely cease, it is required to select an alternative anesthetic which is validated for consistency with existing TGP data acquired under ether anesthesia. We therefore compared two alternative anesthetic candidates, isoflurane and pentobarbital, with ether in terms of hematological findings, serum biochemical parameters, and gene expressions. As a result, few differences among the three agents were observed. In hematological and serum biochemistry analysis, no significant changes were found. In gene expression analysis, four known genes were extracted as differentially expressed genes in the liver of rats anesthetized with ether, isoflurane, or pentobarbital. However, no significant relationships were detected using gene ontology, pathway, or gene enrichment analyses by DAVID and TargetMine. Surprisingly, although it was expected that the lung would be affected by administration via inhalation, only one differentially expressed gene was extracted in the lung. Taken together, our data indicate that there are no significant differences among ether, isoflurane, and pentobarbital with respect to effects on hematological parameters, serum biochemistry parameters, and gene expression. Based on its smallest affect to existing data and its safety profile for humans and animals, we suggest isoflurane as a suitable alternative anesthetic for use in rat euthanasia in toxicogenomics analysis.

  2. Essays on alternative energy policies affecting the US transportation sector

    Science.gov (United States)

    O'Rear, Eric G.

    This dissertation encompasses three essays evaluating the impacts of different policies targeting the greenhouse gas (GHG) emissions, fuel demands, etc. of the transportation sector. Though there are some similarities across the three chapters, each essay stands alone as an independent work. The 2010 US EPA MARKAL model is used in each essay to evaluate policy effects. Essay 1 focuses on the recent increases in Corporate Average Fuel Economy (CAFE) standards, and the implications of a "rebound effect." These increases are compared to a carbon tax generating similar reductions in system-wide emissions. As anticipated, the largest reductions in fuel use by light-duty vehicles (LDV) and emissions are achieved under CAFE. Consideration of the rebound effect does little to distort CAFE benefits. Our work validates many economists' belief that a carbon tax is a more efficient approach. However, because the tax takes advantage of cheaper abatement opportunities in other sectors, reductions in transportation emissions will be much lower than what we observe with CAFE. Essay 2 compares CAFE increases with what some economists suggest would be a much more "efficient" alternative -- a system-wide oil tax internalizing some environmental externalities. Because oil taxes are likely to be implemented in addition to CAFE standards, we consider a combined policy case reflecting this. Our supplementary analysis approximates the appropriate tax rates to produce similar reductions in oil demands as CAFE (CAFE-equivalent tax rates). We discover that taxes result in greater and more cost-effective reductions in system-wide emissions and net oil imports than CAFE. The current fuel tax system is compared to three versions of a national vehicle miles traveled (VMT) tax charged to all LDVs in Essay 3. VMT taxes directly charge motorists for each mile driven and help to correct the problem of eroding tax revenues given the failure of today's fuel taxes to adjust with inflation. Results

    2014-06-01

    Full Text Available Carbon corrosion is a severe issue limiting the long-term stability of carbon-supported catalysts, in particular in the highly dynamic conditions of automotive applications. (Doped oxides have been discussed as suitable alternatives to replace carbon, but often suffer from poor electron conductivity. That is why non-oxide ceramics, such as tungsten carbide and titanium nitride, have been discussed recently. Titanium diboride has also been proposed, due to its promising activity and stability in an aqueous electrochemical cell. In this work, Pt nanoparticles were deposited onto μm-sized TiB2 particles with improved grain size, manufactured into porous gas diffusion electrodes and tested in a realistic polymer electrolyte membrane (PEM fuel cell environment. In contrast to the model studies in an aqueous electrochemical cell, in the presence of oxygen and high potentials at the cathode side of a real fuel cell, TiB2 becomes rapidly oxidized as indicated by intensely colored regions in the membrane-electrode assembly (MEA. Moreover, already the electrode manufacturing process led to the formation of titanium oxides, as shown by X-ray diffraction measurements. This demonstrates that Cyclic Voltammetry (CV measurements in an aqueous electrochemical cell are not sufficient to prove stability of novel materials for fuel cell applications.

    Significant resources and effort have been expended by EPRI over the past few years in modeling and understanding issues related to high-level radioactive waste disposal. Previous reports have documented the general model used in the EPRI work and specific inputs to that model for examination of the potential repository at Yucca Mountain, Nevada. Modeling of the potential Yucca Mountain site is an on-going process, and new data are being collected with which to evaluate and modify models of physical processes. This report is divided into two parts. The first part presents results from specific calculational cases of repository performance, updated for the most recent data and conceptual models. The second part discusses possible alternatives for the components of the assessment context for a repository at Yucca Mountain. Part 2 also presents additional information on time frames and a interaction matrix method of documenting TSPA model interactions. The main purposes of Part of this report is to describe the subsystem and total system performance models and present results and analysis of the results. Part 1 includes presentation of new models of waste container failure that accounts for new container material, a new model of the effect of hydrothermal activity and heterogeneous groundwater flow in the unsaturated zone on temperatures and the distribution of groundwater capable of dripping into the repository drifts. Part 1 also: identifies the key technical components of the candidate spent fuel and HLW disposal facility at Yucca Mountain using IMARC Phase 4; makes recommendations regarding the prioritization of the technical development work remaining; and provides an assessment of the overall technical suitability of the candidate HLW disposal facility at Yucca Mountain

    2011-11-01

    Several scenarios are possible for future international climate policies, each with a different role in the climate negotiations under the United Nations Framework Convention on Climate Change (UNFCCC). These scenarios assume policies that are comparable to the current policies, as well as more fragmented and more integrated international climate policies. The various alternative routes have been assessed with respect to their potential consequences. These assessments showed that none of the proposed routes could fully replace the current negotiation process under the UNFCCC, but rather that they could contribute to generating societal support for future climate policies. In addition, the report presents an analysis of how the Netherlands could use this development of alternative routes for international climate policy. Possible responses by the Netherlands to each of these scenarios would depend on the degree to which climate change as a policy topic is considered a priority in the Netherlands.

  11. Dynamic model of a natural water circulation boiler suitable for on-line monitoring of fossil/alternative fuel plants

    2014-01-01

    Highlights: • Derivation of dynamic model of a natural water circulation boiler is presented. • Model is derived by employing basic laws of conservation of mass, energy and momentum. • Thus obtained boiler model does not include empirical relationships. • Model is validated against experimental data related to an external disturbance event. • The final model is used for simulation analysis/assessment of key boiler quantities. - Abstract: The environmental protection policies and legal obligations motivate process industries to implement new low-emission and high-efficiency technologies. For the purpose of production process optimization and related control system design it is worthwhile to first build an appropriate process model. Apart from favorable execution speed, accuracy, and reliability features, the model also needs to be straightforward and only include the physical and design characteristics of the overall plant and its individual components, instead of relying on empirical relationships. To this end, this paper presents a nonlinear dynamic model of the single-drum natural-circulation steam boiler evaporator circuit, based exclusively on the fundamental physical laws of conservation of mass, energy and momentum, wherein the reliance upon empirical relationships has been entirely avoided. The presented boiler system modeling approach is based on the analysis of the physical phenomena within the boiler drum, as well as within downcomer and furnace tubes, and it also takes into account the boiler system design-specific features such as cyclone steam separators, thus facilitating the derivation of a fully-physical process model. Due to the straightforwardness of the derived process model, it should also be useful for the analysis of similar steam boiler facilities, requiring only adjustments of key operational and design parameters such as operating pressure, temperature, steam capacity and characteristics of ancillary equipment such as pumps.

    2006-01-01

    Full Text Available DTT is one of the existing platforms that can deliver audiovisual content and digital services. Such profile is precisely what includes it in the European Union’s agenda to ensure access to the benefits of Information Society (IS and presents it as the natural successor for the role of offering universal television services once switch-off has taken place. In 1993, a new phase in the history of the European audiovisual policy began, characterized by the concern around the IS and the Convergence. In this context, a positioning regarding digital television arose, conditioning the European policies related to the digitalization of the terrestrial nets in a polarized and subordinated sense. To the study of these DTT policies is devoted this article, which defends the need of its democratization to reach a more efficient terrestrial television service, enabling at the same time, a digital platform that could offer IS services to the whole population.

  13. Economic Impact Assessment of Alternative Climate Policy Strategies

    International Nuclear Information System (INIS)

    Kemfert, C.

    2001-10-01

    This paper investigates the world economic implications of climate change policy strategies, especially the evaluation of impacts by an implementation of Clean Development Mechanisms, Joint Implementation and Emissions trading with a world integrated assessment model. Of special interest in this context are the welfare spill over and competitiveness effects that result from diverse climate policy strategies. In particular, this study elaborates and compares multi gas policy strategies and explores the impacts of the inclusion of sinks. Because of the recent decision of an isolated climate policy strategy by the United States of America, we examine the economic impacts of all world regions by a non cooperative and free rider position of the USA. It turns out that Clean Development Mechanisms and Joint Implementation show evidence of improvement in the economic development in the host countries and increase the share of new applied technologies. The decomposition of welfare effects demonstrates that the competitiveness effect including the spill over effects from trade have the strongest importance because of the intense trade relations between countries. Climatic effects have a significant impact within the next 50 years, cause considerable welfare losses to world regions and will intensify if some highly responsible nations like the USA do not reduce their emissions

  18. New Metrics for Economic Evaluation in the Presence of Heterogeneity: Focusing on Evaluating Policy Alternatives Rather than Treatment Alternatives.

    Science.gov (United States)

    Kim, David D; Basu, Anirban

    2017-11-01

    Cost-effectiveness analysis (CEA) methods fail to acknowledge that where cost-effectiveness differs across subgroups, there may be differential adoption of technology. Also, current CEA methods are not amenable to incorporating the impact of policy alternatives that potentially influence the adoption behavior. Unless CEA methods are extended to allow for a comparison of policies rather than simply treatments, their usefulness to decision makers may be limited. We conceptualize new metrics, which estimate the realized value of technology from policy alternatives, through introducing subgroup-specific adoption parameters into existing metrics, incremental cost-effectiveness ratios (ICERs) and Incremental Net Monetary Benefits (NMBs). We also provide the Loss with respect to Efficient Diffusion (LED) metrics, which link with existing value of information metrics but take a policy evaluation perspective. We illustrate these metrics using policies on treatment with combination therapy with a statin plus a fibrate v. statin monotherapy for patients with diabetes and mixed dyslipidemia. Under the traditional approach, the population-level ICER of combination v. monotherapy was $46,000/QALY. However, after accounting for differential rates of adoption of the combination therapy (7.2% among males and 4.3% among females), the modified ICER was $41,733/QALY, due to the higher rate of adoption in the more cost-effective subgroup (male). The LED metrics showed that an education program to increase the uptake of combination therapy among males would provide the largest economic returns due to the significant underutilization of the combination therapy among males under the current policy. This framework may have the potential to improve the decision-making process by producing metrics that are better aligned with the specific policy decisions under consideration for a specific technology.

    Wahl, Richard

    This quote from the book leads one to speculate as to what will happen to water policy in these times of increased concern for reducing federal spending, for more reliance on state and local governments as opposed to the federal government, and for more reliance on the private sector as opposed to any level of governmental control. Remembering that a wrenching debate preceded deregulation of oil and other energy prices, what are the opportunities for deregulation in the water resources field?Western Water Resources consists of the proceedings of a symposium held in Denver in September 1979 and Hosted by the Federal Reserve Bank of Kansas City. As in any conference, there is, in addition to the organized substantive content of the papers, a mixture of the clever and the banal, peppered with some humor and chit-chat. Among the contributors are economists, including Charles Howe, Allen Kneese, Emery Castle, and Kenneth Boulding; legal scholars, such as George Radosevich and Frank Trelease; and political figures, such as Scott Matheson, Governor of Utah, Guy Martin, former Assistant Secretary for Land and Water Resources of the Department of the Interior, and Leo Eisel, former Director of the Water Resources Council.

    Lenaerts, S; Van Der Borght, M; Callens, A; Van Campenhout, L

    2018-07-15

    Freeze drying represents the current practice to stabilize mealworms, even though it is an energy demanding technique. Therefore, it was examined in the present study whether microwave drying could be a proper alternative. To this end, the impact of both drying techniques on the proximate composition, vitamin B 12 content, fatty acid profile, oxidation status and colour parameters of mealworms was investigated. Furthermore, the influence of the application of vacuum during microwave drying was studied. The different drying technologies resulted in small differences in the proximate composition, while the vitamin B 12 content was only reduced by microwave drying. The fat fraction of freeze dried mealworms showed a higher oxidation status than the fat of microwave dried mealworms. Application of a vacuum during the microwave drying process did not appear to offer advantages. This research shows that for mealworms microwave drying can be a proper alternative to freeze drying.

    To address the climate change issue, developed nations have considered introducing carbon pricing mechanisms in the form of a carbon tax or an emissions trading scheme (ETS). Despite the small number of programmes actually in operation, these mechanisms remain under active discussion in a number of countries, including Japan. Using an input–output model of the Japanese economy, this article analyses the effects of carbon pricing on Japan′s industrial sector. We also examine the impact of a rebate programme of the type proposed for energy-intensive trade-exposed (EITE) industries in U.S. legislation, the Waxman–Markey Bill (H.R. 2454), and in the European Union′s ETS. We find that a carbon pricing scheme would impose a disproportionate burden on a limited number of sectors – namely, pig iron, crude steel (converters), cement and other EITE industries. Out of 401 industries, 23 would be eligible for rebates according to the Waxman–Markey-type programme, whereas 122 industries would be eligible for rebates according to the E.U.-type programme, if adopted in Japan. Overall, despite the differences in coverage, we find that the Waxman–Markey and E.U. rebate programmes have roughly similar impacts in reducing the average burden on EITE industries. - Highlights: • Energy-intensive trade-exposed (EITE) industries suffer the most due to carbon pricing policies. • Twenty-three industries will be eligible under a Waxman–Markey (WM)-type rebate programme. • The E.U. emissions trading scheme (ETS)-type programme identifies 122 industries. • Both WM- and E.U.-type programmes will lower the cost of production to similar levels. • Industries eligible for rebates must be determined carefully

    Instrumental equipment unsuitable or unavailable for fieldwork as well as lack of ship space can necessitate the preservation of seawater samples prior to analysis in a shore-based laboratory. Mercuric chloride (HgCl2) is routinely used for such preservation, but its handling and subsequent disposal incur environmental risks and significant expense. There is therefore a strong motivation to find less hazardous alternatives. Benzalkonium chloride (BAC) has been used previously as microbial inhibitor for freshwater samples. Here, we assess the use of BAC for marine samples prior to the measurement of oxygen-to-argon (O2 / Ar) ratios, as used for the determination of biological net community production. BAC at a concentration of 50 mg dm-3 inhibited microbial activity for at least 3 days in samples tested with chlorophyll a (Chl a) concentrations up to 1 mg m-3. BAC concentrations of 100 and 200 mg dm-3 were no more effective than 50 mg dm-3. With fewer risks to human health and the environment, and no requirement for expensive waste disposal, BAC could be a viable alternative to HgCl2 for short-term preservation of seawater samples, but is not a replacement for HgCl2 in the case of oxygen triple isotope analysis, which requires storage over weeks to months. In any event, further tests on a case-by-case basis should be undertaken if use of BAC was considered, since its inhibitory activity may depend on concentration and composition of the microbial community.

  6. Climate-Determined Suitability of the Water Saving Technology "Alternate Wetting and Drying" in Rice Systems: A Scalable Methodology demonstrated for a Province in the Philippines.

    Andrew Nelson

    Full Text Available 70% of the world's freshwater is used for irrigated agriculture and demand is expected to increase to meet future food security requirements. In Asia, rice accounts for the largest proportion of irrigated water use and reducing or conserving water in rice systems has been a long standing goal in agricultural research. The Alternate Wetting and Drying (AWD technique has been developed to reduce water use by up to 30% compared to the continuously flooded conditions typically found in rice systems, while not impacting yield. AWD also reduces methane emissions produced by anaerobic archae and hence has applications for reducing water use and greenhouse gas emissions. Although AWD is being promoted across Asia, there have been no attempts to estimate the suitable area for this promising technology on a large scale. We present and demonstrate a spatial and temporal climate suitability assessment method for AWD that can be widely applied across rice systems in Asia. We use a simple water balance model and easily available spatial and temporal information on rice area, rice seasonality, rainfall, potential evapotranspiration and soil percolation rates to assess the suitable area per season. We apply the model to Cagayan province in the Philippines and conduct a sensitivity analysis to account for uncertainties in soil percolation and suitability classification. As expected, the entire dry season is climatically suitable for AWD for all scenarios. A further 60% of the wet season area is found suitable contradicting general perceptions that AWD would not be feasible in the wet season and showing that spatial and temporal assessments are necessary to explore the full potential of AWD.

    Road traffic noise is one of the most significant environmental impacts generated by transport systems. To this regard, the recent implementation of the European Environmental Noise Directive by Public Administrations of the European Union member countries has led to various noise action plans (NAPs) for reducing the noise exposure of EU inhabitants. Every country or administration is responsible for applying criteria based on their own experience or expert knowledge, but there is no regulated process for the prioritization of technical measures within these plans. This paper proposes a multi-criteria decision methodology for the selection of suitable alternatives against traffic noise in each of the road stretches included in the NAPs. The methodology first defines the main criteria and alternatives to be considered. Secondly, it determines the relative weights for the criteria and sub-criteria using the fuzzy extended analytical hierarchy process as applied to the results from an expert panel, thereby allowing expert knowledge to be captured in an automated way. A final step comprises the use of discrete multi-criteria analysis methods such as weighted sum, ELECTRE and TOPSIS, to rank the alternatives by suitability. To illustrate an application of the proposed methodology, this paper describes its implementation in a complex real case study: the selection of optimal technical solutions against traffic noise in the top priority road stretch included in the revision of the NAP of the regional road network in the province of Almeria (Spain).

    Full Text Available The impacts of AMD pollution on biological systems are mostly severe and the problem may persist from many decadesto thousands of years. Consequently AMD prior to being released into the environment must be treated to meet government standardsfor the amount of metal and non-metal ions contained in the water. One of the best available technologies for the removal of metals fromAMD is precipitation as metal sulphides. SRB applications for AMD treatment involve a few principal stages. The first stageis the cultivation of SRB i.e. the bacterial sulphate reduction. At the laboratory conditions the sodium lactate is the energetic substratefor the growth of bacteria. Its price is not economic for the application in the practice and is needed investigate the alternativesubstitutes. The aim of this work was the cultivation of SRB using the selected energetic substrates such as: calcium lactate, ethanol,saccharose, glucose and whey. Experimental studies confirm that in the regard to the amount of reduced sulphates the calcium lactateand ethanol are the best alternative substrates for the bacterial sulphate-reduction.

    Yang, Honglin; Wang, Lin; Tian, Lixin

    2015-01-01

    This work is devoted to the evolution of the competition of energy alternative pathway in China, and the influence of energy policy on economic growth by using a dynamical system method. Firstly, the relation between energy and economic growth is taken into account, and a dynamic evolution model is established. It is observed that Hopf bifurcation and chaotic behavior occurs with the varying investment in renewable energy production. Secondly, when there is no policy intervention in energy market, the evolution of competition in energy alternative pathway is also investigated. Thirdly, the system parameters are also identified by using an artificial neural network method on the basis of certain empirical statistical data in China, and the dynamics of the parameters-identified system are studied. Finally, the influences of energy policy on economic growth are empirically analyzed, and some policy recommendations are given based on the results of empirical analysis. - Highlights: • Modeling the energy economy system via the method of dynamic system. • Attaining the chaotic attractor of the energy production and economic system. • Discovering the Hopf bifurcation when the investment changes. • Proposing the alternative pathway of free competition in energy production. • Determining the turning points of parameters related to policy regulation

  14. Environmental cost-effectiveness of bio diesel production in Greece: Current policies and alternative scenarios

    Iliopoulos, Constantine; Rozakis, Stelios

    2010-01-01

    Following European Directive 2003/30/EC, the Greek Government adapted legislation that introduces and regulates the bio diesel market. The implemented quota scheme allocates the country's annual, predetermined, tax exempt production of bio diesel to industries based on their ability to meet several criteria. A number of bio diesel supply chain stakeholders have criticized this policy for being efficiency-robbing and vague. This paper uses 2007 data from energy crop farms and three bio diesel-producing companies in order to assess these criticisms. We study the economic and environmental aspects of the currently adopted policy and compare them to three alternative scenarios. We conclude that such criticisms have a merit and that policy makers need to reconsider their alternative options regarding the promotion of bio diesel in transport. Permission of sales directly to local consumers and promotion of forward integration by farmers are efficiency enhancing and environment-friendly means of promoting the use of bio diesel in transport.

  15. Is Grey Level a Suitable Alternative to Low-Contrast Penetration as a Serial Measure of Sensitivity in Computerised Ultrasound Quality Assurance?

    Science.gov (United States)

    Dudley, Nicholas J; Gibson, Nicholas M

    2017-02-01

    The aim of this study was to test the hypothesis that grey levels are a suitable alternative measure of sensitivity in ultrasound imaging quality assurance, as there are several caveats in the use of penetration depth. In a primary cohort of nine probes, where measurements had been made for 6 to 34 mo, both penetration depth and mean grey level fell below tolerance for six probes; both penetration depth and mean grey level remained within tolerance for three probes. In a secondary cohort where a measurement programme had been in place for a shorter period, grey level and/or penetration depth fell below tolerance in 15 of 66 probes; the sensitivity and specificity of at least 10% loss of grey level in predicting >5% loss in penetration depth were 91% and 93%, respectively. A loss of grey level accompanies a loss of penetration and provides a suitable alternative measure of sensitivity. Crown Copyright © 2016. Published by Elsevier Inc. All rights reserved.

    benefits of RES, there may be valid reasons for policy makers not to employ auctions, since under particular circumstances it may be desirable not to control quantities but the price. As such, they raise the question whether pure support cost minimisation should be the only goal when implementing......This report concludes the work carried out in the course of Task 6.2 of the AURES project. It is its aim to compare auctions with alternative policy instruments and in particular, to examine under which circumstances auctions may be superior and inferior to achieve intended policy targets....... For that purpose, we identify a number of potential drivers that might affect an instrument’s effectiveness, its efficiency and further success criteria. Among this list of relevant drivers, the basis for our analysis is the factor risk, where our core focus is on risk for policy makers. Assuming a world...

  17. Alternative energy facility siting policies for urban coastal areas: executive summary of findings and policy recommendations

    Energy Technology Data Exchange (ETDEWEB)

    Morell, D; Singer, G

    1980-11-01

    An analysis was made of siting issues in the coastal zone, one of the nation's most critical natural resource areas and one which is often the target for energy development proposals. The analysis addressed the changing perceptions of citizens toward energy development in the coastal zone, emphasizing urban communities where access to the waterfront and revitalization of waterfront property are of interest to the citizen. The findings of this analysis are based on an examination of energy development along New Jersey's urban waterfront and along the Texas-Louisiana Gulf Coast, and on redevelopment efforts in Seattle, San Francisco, Boston, and elsewhere. The case studies demonstrate the significance of local attitudes and regional cooperation in the siting process. In highly urbanized areas, air quality has become a predominant concern among citizen groups and an influential factor in development of alternative energy facility siting strategies, such as consideration of inland siting connected by pipeline to a smaller coastal facility. The study addresses the economic impact of the permitting process on the desirability of energy facility investments, and the possible effects of the location selected for the facility on the permitting process and investment economics. The economic analysis demonstrates the importance of viewing energy facility investments in a broad perspective that includes the positive or negative impacts of various alternative siting patterns on the permitting process. Conclusions drawn from the studies regarding Federal, state, local, and corporate politics; regulatory, permitting, licensing, environmental assessment, and site selection are summarized. (MCW)

    2013-07-01

    Full Text Available Recent increases in global demand for palm oil have resulted in rapid, widespread deforestation in Indonesia, making Indonesia the third largest emitter of greenhouse gases in the world. Although the Indonesian government has sought to pursue progressive environmental policies to curb deforestation, such as through REDD+, implementation has been hampered by legal loopholes, corruption and weak rule of law. This paper will examine two alternative carbon sequestration policies to REDD+: a drying up of the palm oil market and a buy-out of palm oil plantations.

    Johnson, Bruce D; Golub, Andrew; Dunlap, Eloise; Sifaneck, Stephen J

    2008-01-01

    During the 1990s, the New York Police Department (NYPD) instituted a policy of arresting and detaining people for minor offenses that occur in public as part of their quality-of-life (hereafter QOL) policing initiative. The number of NYPD arrests for smoking marijuana in public view (MPV) increased from 3,000 in 1994 to over 50,000 in 2000, and have been about 30,000 in the mid 2000s. Most of these arrestees (84%) have been minority; blacks have been 2.7 more likely and Hispanics 1.8 times more likely to be detained than whites for an MPV arrest. Minorities have been most likely to receive more severe dispositions, even controlling for demographics and prior arrest histories.This paper examines the pros and cons of the current policy; this is compared with possible alternatives including the following: arrest and issue a desk appearance ticket (DAT); issue a non-criminal citation (violation); street warnings; and tolerate public marijuana smoking. The authors recommend that the NYPD change to issuing DATs on a routine basis. Drug policy reformers might wish to further pursue changing statutes regarding smoking marijuana in public view into a violation (noncriminal) or encourage the wider use of street warnings. Any of these policy changes would help reduce the disproportionate burden on minorities associated with the current arrest and detention policy. These policies could help maintain civic norms against smoking marijuana in public.

    1995-01-01

    Public acceptance has become an important factor in nuclear power program particularly after Chernobyl accident and recent rapid democratization in Korea. A method reflecting public opinions in order to improve public acceptance is to find out the public preference values for its policy alternatives. In this study, the conjoint analysis was applied to find out the quantitative values of public preferences for twelve policy alternatives to support communities surrounding nuclear power plants in Korea. To implement the analysis, questionnaires of trade-off matrix form were mailed to the science teachers of middle or high school through-out the country who had the experience of visiting nuclear power plant. The quantitative preference values for potential policy alternatives were estimated, which made it possible to forecast the effectiveness of each option. It was revealed that the improvement of reactor safety 100 times and the establishment of civilian monitoring system for nuclear safety would be two best options to improve public acceptance of nuclear power in Korea.

    1997-01-01

    Feasible policy alternatives are searched for, which could tackle the job market problem, thus achieving the first step towards solving the biomass dependency issue. To do this, an economic model is built which includes specific characteristics of biomass collection and use, such as non-monetary income, determinants of time allocation between formal and informal activities, and energy sources substitutability. The economic features of biomass production and use is studied in order to understand the underlying principles at work at the cross-roads between rural labour market and energy consumption patterns. The issue of fuelwood plantation is examined on a commercial basis using a spread-sheet model to assess its viability and the constraints for the policy maker. An economic model is developed to test the effects of a variety of policy changes on the local economy as described in the spread-sheet framework. The case of India is studied. (K.A.)

  6. Welfare Implications of Alternative Monetary Policy Rules: A New Keynesian DSGE Model for Turkey

    Directory of Open Access Journals (Sweden)

    Yağcıbaşı Özge Filiz

    2017-12-01

    Full Text Available In recent years, there has been extensive research on the conduct of monetary policy in small open economies that are subject to inflation and output fluctuations. Policymakers should decide whether to implement strict inflation targeting or to respond to the changes in output fluctuations while conducting monetary policy rule. This study aims to examine the response of alternative monetary policy rules to Turkish economy by means of a DSGE model that is subject to demand and technology shocks. The New Keynesian model we used is borrowed from Gali (2015 and calibrated for the Turkish economy. Welfare effects of alternative Taylor rules are evaluated under different specifications of central bank loss function. One of the main findings of this paper is that in the case of a technology shock, strict inflation targeting rules provide the minimum welfare loss under all loss function configurations. On the contrary, the losses are weakened if the monetary authority responds to output fluctuations in the presence of a demand shock. Finally, there exists a trade-off between the volatility of output and inflation in case of a technology shock, while the volatility of both variables moves in the same direction in response to a demand shock.

    2015-08-28

    In this report, we examine and compare how tradable mass-based polices and tradable rate-based policies create different incentives for energy efficiency investments. Through a generalized demonstration and set of examples, we show that as a result of the output subsidy they create, traditional rate-based policies, those that do not credit energy savings from efficiency measures, reduce the incentive for investment in energy efficiency measures relative to an optimally designed mass-based policy or equivalent carbon tax. We then show that this reduced incentive can be partially addressed by modifying the rate-based policy such that electricity savings from energy efficiency measures are treated as a source of zero-carbon generation within the framework of the standard, or equivalently, by assigning avoided emissions credit to the electricity savings at the rate of the intensity target. These approaches result in an extension of the output subsidy to efficiency measures and eliminate the distortion between supply-side and demand-side options for GHG emissions reduction. However, these approaches do not address electricity price distortions resulting from the output subsidy that also impact the value of efficiency measures. Next, we assess alternative approaches for crediting energy efficiency savings within the framework of a rate-based policy. Finally, we identify a number of challenges that arise in implementing a rate-based policy with efficiency crediting, including the requirement to develop robust estimates of electricity savings in order to assess compliance, and the requirement to track the regionality of the generation impacts of efficiency measures to account for their interstate effects.

    2006-01-01

    Energy is often known as the catalyst for development. Globally, the per capita consumption of energy is often used as a barometer to measure the level of economic development in a particular country. Realizing the importance of energy as a vital component in economic and social development, the government of Malaysia has been continuously reviewing its energy policy to ensure long-term reliability and security of energy supply. Concentrated efforts are being undertaken to ensure the sustainability of energy resources, both depletable and renewable. The aim of this paper is to describe the various energy policies adopted in Malaysia to ensure long-term reliability and security of energy supply. The role of both, non-renewable and renewable sources of energy in the current Five-Fuel Diversification Strategy energy mix will also be discussed. Apart from that, this paper will also describe the various alternative energy and the implementation of energy efficiency program in Malaysia

  10. California's greenhouse gas law, Assembly Bill 1493: Deficiencies, alternatives, and implications for regulatory climate policy

    International Nuclear Information System (INIS)

    Johnson, Kenneth C.

    2007-01-01

    California's Air Resources Board has finalized regulations implementing Assembly Bill (AB) 1493, which requires 'maximum feasible and cost-effective reduction of greenhouse gas emissions from motor vehicles'. By 2030, when California's light-duty vehicle stock has been substantially replaced by regulation-compliant vehicles, total emissions from regulated vehicles are projected to be reduced by 27% relative to 'business-as-usual', but are nevertheless expected to be 8.7% higher than 2004 emissions. If an 8.7% increase truly represents the 'maximum feasible and cost-effective' emissions reduction from transportation vehicles, then global climate stabilization clearly will not be attained within limits of 'feasibility' and 'cost-effectiveness', and climate sustainability will only be achievable through severely draconian measures. On the other hand, if significantly greater emissions reduction would be feasible and cost-effective, then the AB 1493 regulations fail to satisfy the legislative policy mandate and the task is to find a regulatory mechanism that will. The thesis of this paper is that the regulations do not satisfy the mandate for several reasons, the most important being the conflicting policy objectives of the 'cost-constrained' legislative mandate and the 'quantity-constrained', standard-based regulatory instrument. An alternative policy instrument that would better fit legislative policy and environmental objectives would be a feebate-type system (although not necessarily a conventional vehicle feebate)

Recent work with businesses and communities indicates that creating a shared vision is the most effective engine for change in the desired direction, yet most effort in "futures modeling" has focused on extrapolating past trends rather than envisioning alternative futures. Science and economics as applied to policy are in conflict more often over alternative visions of the world than purely "scientific" disagreements. Likewise, governance has gotten bogged down in mediating short term conflicts between special interests rather than its more basic role of creating broadly shared visions that can guide dispute resolution. This paper addresses the question of what policies are most appropriate for society now, given alternative visions of the future and the enormous uncertainty about the reality of the assumptions underlying these visions. Four specific visions are laid out as being representative of the major alternatives. For each vision the benefits of achieving the vision, the assumptions that would have to be true in order for it to be achieved, and the implications of it being attempted but not achieved are explored. It is argued that dealing with uncertainty about the nature of the world, its carrying capacity for humans, the impacts of climate change, and other aspects of its future can best be done at this level of future visions and assumptions, not at more detailed levels (like the parameter uncertainty in models. Application of this vision/uncertainty analysis can help us both to design the future society we want and to maximize the chances of our getting there safely.

    Full Text Available This paper is a review of the social conflicts of indigenous peoples especially in North Maluku. The purpose of this review is to find out some factors causing indigenous peoples social conflicts in North Maluku and to produce alternative solutions as a policy to develop indigenous peoples livelihoods. The review resulted in several factors causing social conflicts of indigenous peoples such as the unclear boundary between the two parties the customary violations by the forest businessmen the injustice of the law enforcement officers in solving the problems the destruction of the indigenous people and the forest community narrow forest the lack positive contribution of forest management so far to indigenous peoples and forest communities companies do not involve indigenous peoples andor forest communities in forest exploitation destruction of customary buildings as places of worship deforestation timber exploitation while timber by indigenous peoples is sacred wood or abstinence to be felled. Alternative solutions are required by local government such as policy on legal recognition of indigenous peoples indigenous peoples empowerment implementation of indigenous peoples aspirations indigenous peoples economic development based on local wisdom and dispute resolution of indigenous peoples through special courts of a holistic nature.

  15. Alternative Monetary Policy Rules in a Small Open Economy with Financial Frictions: The Case of Korea

    2011-09-01

    Full Text Available This paper first shows an empirical result of VAR that Korean economy has experienced a severe economic contraction to an exogenous country spread shock. To analyze the effect of alternative monetary policy on the economy, the paper sets up a multi-sector small open economy new Keynesian (NK hereafter model with financial frictions due to asymmetric information between firms and financial intermediaries along the line of Bernanke et al. (1999. It shows that the small economy with financial frictions is more vulnerable to the exogenous shocks such as the foreign exchange rate shock under the fixed exchange rate regime than under the flexible exchange regime. It also shows that the interest rate rule that responds to financial market conditions is better than any other interest rate rules only if it does not react to the exchange rate fluctuations. Moreover, an interest rate rule that responds to the exchange rate fluctuations, i.e. the monetary policy under the managed floating exchange rate regime is inferior to the monetary policy rules that do not respond to the exchange rate fluctuations. Finally, it shows that the monetary authority needs to stabilize a narrow price index such as domestic price index rather than a general price index such as consumer price index under the financial friction circumstances.

    This research assesses climate, technological, and policy impacts on consumptive water use from electricity generation in the Southwest over a planning horizon of nearly a century. We employed an integrated modeling framework taking into account feedbacks between climate change, air temperature and humidity, and consequent power plant water requirements. These direct impacts of climate change on water consumption by 2095 differ with technology improvements, cooling systems, and policy constraints, ranging from a 3-7% increase over scenarios that do not incorporate ambient air impacts. Upon additional factors being changed that alter electricity generation, water consumption increases by up to 8% over the reference scenario by 2095. With high penetration of wet recirculating cooling, consumptive water required for low-carbon electricity generation via fossil fuels will likely exacerbate regional water pressure as droughts become more common and population increases. Adaptation strategies to lower water use include the use of advanced cooling technologies and greater dependence on solar and wind. Water consumption may be reduced by 50% in 2095 from the reference, requiring an increase in dry cooling shares to 35-40%. Alternatively, the same reduction could be achieved through photovoltaic and wind power generation constituting 60% of the grid, consistent with an increase of over 250% in technology learning rates.

  17. Input-output analysis of alternative policies implemented on the energy activities: An application for Catalonia

    2008-01-01

    The aim of this paper is to analyze the economic impact of alternative policies implemented on the energy activities of the Catalan production system. Specifically, we analyze the effects of a tax on intermediate energy uses, a reduction in intermediate energy demand, and a tax on intermediate uses combined with a reduction in intermediate energy demand. The methodology involves two versions of the input-output price model: a competitive price formulation and a mark-up price formulation. The input-output price framework will make it possible to evaluate how the alternative measures modify production prices, consumption prices, private real income, and intermediate energy uses. The empirical application is for the Catalan economy and uses economic data for the year 2001. The combination of a tax on energy uses and an improvement in the energy efficiency of the production system is a measure that accomplishes both economic and environmental goals, since it has no effects on prices, it has a positive effect on private real income and, finally, energy consumption is considerably reduced.

    Two competing approaches to policy analysis are distinguished: a credibility approach, and a truth approach. According to the credibility approach, the policy analyst's role is to search for plausible argument rather than truth. Each approach has pragmatic tradeoffs in fulfilling the goal of providing usable knowledge to decision makers. (TJH)

  19. Resource acquisition policy: Multiple account evaluation of electricity resource alternatives [and] resource acquisition strategy

    1994-06-01

    British Columbia Hydro has been directed by the provincial government to develop evaluation procedures to rank electricity resource alternatives in terms of their social benefits and costs, and to acquire resources on the basis of need. The current state of development of social costing at BC Hydro is detailed along with its application to the multiple account evaluation of resources. In this evaluation, BC Hydro's corporate costs, customer cost, transfer payments to the province, direct costs incurred by provincial or regional governments or other Crown agences, direct environmental impact costs from air emissions and land/water use, community and social impact costs, and economic development impacts are taken into account. The BC Hydro resource acquisition strategy is also described as it was developed in response to provincial policy on electricity supply from independent power producers. This strategy includes a determination of need, a decision to acquire need-determined resources either by itself or from a private sector developer, and decisions to acquire resources in advance of need for reasons such as economic opportunity, long-term strategies, or load displacement. Background information is included on calculation of air emissions costs. An illustrative example is provided of the multiple account evaluation of several types of resource projects. 1 fig., 5 tabs

    2016-09-01

    The purpose of this project was to examine the policy implications of politically defining complementary and alternative medicine (CAM) professions by their treatment modalities rather than by their full professional scope. This study used a 2-stage exploratory grounded approach. In stage 1, we identified how CAM is represented (if considered as professions vs modalities) across a purposely sampled diverse set of policy topic domains using exemplars to describe and summarize each. In stage 2 we convened 2 stakeholder panels (12 CAM practitioners and 9 health policymaker representatives), and using the results of stage 1 as a starting point and framing mechanism, we engaged panelists in a discussion of how they each see the dichotomy and its impacts. Our discussion focused on 4 licensed CAM professions: acupuncture and Oriental medicine, chiropractic, naturopathic medicine, and massage. Workforce policies affected where and how members of CAM professions could practice. Licensure affected whether a CAM profession was recognized in a state and which modalities were allowed. Complementary and alternative medicine research examined the effectiveness of procedures and modalities and only rarely the effectiveness of care from a particular profession. Treatment guidelines are based on research and also focus on procedures and modalities. Health plan reimbursement policies address which professions are covered and for which procedures/modalities and conditions. The policy landscape related to CAM professions and modalities is broad, complex, and interrelated. Although health plan reimbursement tends to receive the majority of attention when CAM health care policy is discussed, it is clear, given the results of our study, that coverage policies cannot be addressed in isolation and that a wide range of stakeholders and social institutions will need to be involved.

  4. Economic and environmental performance of alternative policy measures to reduce nutrient surpluses in Finnish agriculture

    Directory of Open Access Journals (Sweden)

    H. LEHTONEN

    2008-12-01

    Full Text Available This paper provides an economic sector level analysis of the effectiveness of different policy measures in decreasing nitrogen (N and phosphorus (P surpluses from agriculture in order to reduce nutrient runoff from agricultural fields to watercourses and to improve water quality of surface waters. Assuming no changes in the EU level policies after CAP reform 2003 we focus on national level policy measures such as full or partial de-coupling of national support from production, payments for reduced nutrient surpluses of N and P, and N fertiliser tax. None of the analysed policy measures is superior one with respect to environmental performance, since full decoupling of national support would be the most effective in reducing P surpluses while payment for reduced nutrient surplus performed best with respect to N surpluses. Economic performance (farmers’ compliance cost per %-reduction of N or P surplus of full and partial de-coupling of national support is clearly better than that of specialised agri-environmental policy instruments, because both decoupling scenarios result in the increase of farmers’ income in comparison to base scenario, and thus compliance costs are in fact negative in these two cases. Our analysis confirms the fact that the overall policy package matters a lot for the effectiveness of agrienvironmental policy measures. Environmental performance of agri-environmental policy measures may be significantly reduced, if they are implemented jointly with production coupled income support policies. Thus, in order to increase the effectiveness of agri-environmental policy measures agricultural income support policies should be decoupled from production and this alone would bring substantial reduction in nutrient surpluses.;

    2010-01-01

    The Chinese government has enacted policies to promote alternative vehicle fuels (AVFs) and alternative fuel vehicles (AFVs), including city bus fleets. The life cycle (LC), energy savings (ES) and GHG reduction (GR) profiles of AVFs/AFVs are critical to those policy decisions. The well-to-wheels module of the Tsinghua-CA3EM model is employed to investigate actual performance data. Compared with conventional buses, AFVs offer differences in performance in terms of both ES and GR. Only half of the AFVs analyzed demonstrate dual benefits. However, all non-oil/gas pathways can substitute oil/gas with coal. Current policies seek to promote technology improvements and market creation initiatives within the guiding framework of national-level diversification and district-level uniformity. Combined with their actual LC behavior and in keeping with near- and long-term strategies, integrated policies should seek to (1) apply hybrid electric technology to diesel buses; (2) encourage NG/LPG buses in gas-abundant cities; (3) promote commercialize electric buses or plug-in capable vehicles through battery technology innovation; (4) support fuel cell buses and hydrogen technology R and D for future potential applications; and (5) conduct further research on boosting vehicle fuel efficiency, applying low-carbon transportation technologies, and addressing all resultant implications of coal-based transportation solutions to human health and natural resources.

    1995-01-01

    Public acceptance has become an important factor in nuclear power program particularly after Chernobyl accident and recent rapid democratization in Korea. Methods reflection public opinions in order to improve public acceptance are firstly to understand what the public think about nuclear power plant and secondly to find out the public preference values for its policies. For this purpose, simplified multi-attribute utility(MAU) model was applied to analyze the public perception for five power production system. And the conjoint analysis was applied to find out he quantitative values of public preferences for twelve policy alternatives to improve the safety and support communities surrounding nuclear power plants in Korea. To implement these perception and preference analyses, mail survey was conducted to the qualified sample who had the experience of visiting nuclear power plant. Diagnosis of their perception pattern for five power production systems was made by the simplified MAU model. Estimation of the quantitative preference values for potential policy alternatives was made by the conjoint measurement technique, which made it possible to forecast the effectiveness of each option. The results from the qualified sample and the methods used in this study would be helpful to set up new policy of nuclear power plant. 4 figs., 7 tabs., 18 refs. (Author)

  10. Stimulating learning-by-doing in advanced biofuels: effectiveness of alternative policies

    International Nuclear Information System (INIS)

    Chen Xiaoguang; Khanna, Madhu; Yeh, Sonia

    2012-01-01

    This letter examines the effectiveness of various biofuel and climate policies in reducing future processing costs of cellulosic biofuels due to learning-by-doing. These policies include a biofuel production mandate alone and supplementing the biofuel mandate with other policies, namely a national low carbon fuel standard, a cellulosic biofuel production tax credit or a carbon price policy. We find that the binding biofuel targets considered here can reduce the unit processing cost of cellulosic ethanol by about 30% to 70% between 2015 and 2035 depending on the assumptions about learning rates and initial costs of biofuel production. The cost in 2035 is more sensitive to the speed with which learning occurs and less sensitive to uncertainty in the initial production cost. With learning rates of 5–10%, cellulosic biofuels will still be at least 40% more expensive than liquid fossil fuels in 2035. The addition of supplementary low carbon/tax credit policies to the mandate that enhance incentives for cellulosic biofuels can achieve similar reductions in these costs several years earlier than the mandate alone; the extent of these incentives differs across policies and different kinds of cellulosic biofuels.

  11. Alternative policy impacts on US GHG emissions and energy security: A hybrid modeling approach

    International Nuclear Information System (INIS)

    Sarica, Kemal; Tyner, Wallace E.

    2013-01-01

    This study addresses the possible impacts of energy and climate policies, namely corporate average fleet efficiency (CAFE) standard, renewable fuel standard (RFS) and clean energy standard (CES), and an economy wide equivalent carbon tax on GHG emissions in the US to the year 2045. Bottom–up and top–down modeling approaches find widespread use in energy economic modeling and policy analysis, in which they differ mainly with respect to the emphasis placed on technology of the energy system and/or the comprehensiveness of endogenous market adjustments. For this study, we use a hybrid energy modeling approach, MARKAL–Macro, that combines the characteristics of two divergent approaches, in order to investigate and quantify the cost of climate policies for the US and an equivalent carbon tax. The approach incorporates Macro-economic feedbacks through a single sector neoclassical growth model while maintaining sectoral and technological detail of the bottom–up optimization framework with endogenous aggregated energy demand. Our analysis is done for two important objectives of the US energy policy: GHG reduction and increased energy security. Our results suggest that the emission tax achieves results quite similar to the CES policy but very different results in the transportation sector. The CAFE standard and RFS are more expensive than a carbon tax for emission reductions. However, the CAFE standard and RFS are much more efficient at achieving crude oil import reductions. The GDP losses are 2.0% and 1.2% relative to the base case for the policy case and carbon tax. That difference may be perceived as being small given the increased energy security gained from the CAFE and RFS policy measures and the uncertainty inherent in this type of analysis. - Highlights: • Evaluates US impacts of three energy/climate policies and a carbon tax (CT) • Analysis done with bottom–up MARKAL model coupled with a macro model • Electricity clean energy standard very close to

    Dittman, D A; Morey, R C

    1983-01-01

    This paper applies and extends the use of a nonlinear hospital pricing model, recently posited in the literature by Dittman and Morey [1]. That model applied a hospital profit-maximizing behavior and studied the effects of optimal pricing of hospital ancillary services on the incidence of payment by private insurance companies and the Medicare trust fund. Here, we examine variations of the above model where both hospital profit-maximizing and profit-satisficing postures are of interest. We apply the model to three types of Medicare reimbursement policies currently in use or under legislative mandate to implement. The policies differ according to hospital size and whether cross-subsidies are allowed. We are interested in determining the effects of profit-maximizing and -satisficing behaviors of these three reimbursement policies on the levels of profits received, and on the respective implications for private payors and the Medicare trust fund.

    2006-01-01

    This paper assessed the economic impact of alternative depreciation methods on the development of combined heat-and-power (CHP) systems in the Brazilian industrial sector. Alternative depreciation methods were proposed and the case study of a Brazilian chemical plant showed that the most effective depreciation method for the promotion of CHP plants in Brazil was the Matheson method with an accelerated depreciation schedule of 7 years. This alternative method was then applied to the Brazilian chemical industry as a whole, increasing its installed capacity in CHP systems by 24%. Therefore, fiscal incentives can be an interesting tool for promoting energy efficiency in the Brazilian industrial sector, promoting the expansion of CHP plants. It reduces government fiscal revenues, but it also induces the technological reposition and improves the feasibility of ventures that are not installed without this kind of incentive

Whether it is in the form of oil, gasoline or electricity, a country's prosperity and welfare depends on having access to reliable and secure supplies of energy at affordable prices. However, it is also one of the benefits taken for granted by many people, knowing little about the impact of electricity on their lives. Having dependent mainly on oil and gas for half a century, Malaysia has started to realize the importance to adopt renewable energy in the energy mix and continuously reviewed its energy policy to ensure sustainable energy supply and security. This paper examines and discusses the intricacy of the existing and new energy policies, issues and challenges in Malaysia. The overall approach in addressing the energy issues and challenges will continue to focus on adequacy, quality, security and sustainability of both non-renewable and renewable energy supply in the country's development and the promotion and implementation of its energy efficiency programs. The recently launched National Green Technology Policy is also discussed. (author)

    The potential instability of a fixed monetary rule combined with automatic fixed stabilisers is a well-established feature of closed economy IS/LM models with wealth effects and asset accumulation. This paper examines the stability issue in a general open economy macromodel with alternative expectations mechanisms (rational or adaptive) in both the labour market and the foreign exchange market. The fixed monetary rule is found to be stabilising only in special cases, notably when post-tax rea...

    Grassland bird habitat has declined substantially in the United States. Remaining grasslands are increasingly fragmented, mostly privately owned, and vary greatly in terms of habitat quality and protection status. A coordinated strategic response for grassland bird conservation is difficult, largely due to the scope and complexity of the problem, further compounded by biological, sociological, and economic uncertainties. We describe the results from a collaborative Structured Decision Making (SDM) workshop focused on linking social and economic drivers of landscape change to grassland bird population outcomes. We identified and evaluated alternative strategies for grassland bird conservation using a series of rapid prototype models. We modeled change in grassland and agriculture cover in hypothetical landscapes resulting from different landowner decisions in response to alternative socio-economic conservation policy decisions. Resulting changes in land cover at all three stages of the annual cycle (breeding, wintering, and migration) were used to estimate changes in grassland bird populations. Our results suggest that successful grassland bird conservation may depend upon linkages with ecosystem services on working agricultural lands and grassland-based marketing campaigns to engage the public. With further development, spatial models that link landowner decisions with biological outcomes can be essential tools for making conservation policy decisions. A coordinated non-traditional partnership will likely be necessary to clearly understand and systematically respond to the many conservation challenges facing grassland birds.

    This report is the first of a series of studies that will analyze the economic and social impacts of research, development, and demonstration plans of the Energy Research and Development Administration. Two policy proposals were examined against a Base Case set of economic and energy projections for the years 1985, 1990, and 2000: (1) the introduction of RD and D-initiated energy supply and end-use conversion technologies to expand domestic energy supply and to improve the efficiency and flexibility of its use; and (2) the imposition of taxes and tariffs on petroleum and natural gas to reduce demand for these primary energy sources. Targets for the amounts of imports of oil and gas were specified by ERDA as follows: 10 percent (or less) of total U.S. energy consumption in 1985; 8 percent (or less) of total U.S. energy consumption in 1990; and 5 percent (or less) of total U.S. energy consumption in 2000. The purpose of the analysis was to first identify the degree to which the introduction of new energy technologies and/or the imposition of energy taxes could reduce oil and gas imports toward the target levels; and second, to estimate the effects of these policies on the economy and the environment. These economic and environmental effects are thus a measure of the costs associated with meeting the import targets. The benefits of these policies, in the form of increased economic and political security were not measured. The analysis was based on an analytic framework which linked detailed mathematical process engineering and economic models to more aggregate econometric models. The four models employed are described.

  7. Assessment of Climate Suitability of Maize in South Korea

    Assessing suitable areas for crops would be useful to design alternate cropping systems as an adaptation option to climate change adaptation. Although suitable areas could be identified by using a crop growth model, it would require a number of input parameters including cultivar and soil. Instead, a simple climate suitability model, e.g., EcoCrop model, could be used for an assessment of climate suitability for a major grain crop. The objective of this study was to assess of climate suitability for maize using the EcoCrop model under climate change conditions in Korea. A long term climate data from 2000 - 2100 were compiled from weather data source. The EcoCrop model implemented in R was used to determine climate suitability index at each grid cell. Overall, the EcoCrop model tended to identify suitable areas for maize production near the coastal areas whereas the actual major production areas located in inland areas. It is likely that the discrepancy between assessed and actual crop production areas would result from the socioeconomic aspects of maize production. Because the price of maize is considerably low, maize has been grown in an area where moisture and temperature conditions would be less than optimum. In part, a simple algorithm to predict climate suitability for maize would caused a relatively large error in climate suitability assessment under the present climate conditions. In 2050s, the climate suitability for maize increased in a large areas in southern and western part of Korea. In particular, the plain areas near the coastal region had considerably greater suitability index in the future compared with mountainous areas. The expansion of suitable areas for maize would help crop production policy making such as the allocation of rice production area for other crops due to considerably less demand for the rice in Korea.

    In most western cities the present-day car is by far the principal mode of transport. The wrong side of it is that automobile circulation is a source of air-pollution, noise and traffic jam, inconveniences against which public opinion shows itself more and more susceptible. Facing this situation governments in succession have since several years encouraged by different measures the development of fitted or alternative vehicles: electric, natural gas (NG) fuelled and liquefied petroleum gas (LPG) vehicles. These vehicles have the advantage of responding both to pollution problem and energy diversification challenge. The present-day regulation system gathers a number of attractive provisions: - maintaining para-fiscal taxes upon gas fuels at a level much lower than for other fuels; - VAT refunding for these gas fuels and electricity consumed by vehicles of this type; - general councils can be totally or partially exonerated from automobile taxation; - assigning future green label allowing these vehicles to be excepted from traffic restrictions applied to cope with pollution peaks. Other additional advantages are provided by the law on air and rational use of energy of 30 December 1996. Merits and drawbacks of each of the mentioned types of alternative vehicles are reviewed. So, although entirely un-polluting the electric cars are not cheap and what is even more hindering is their very limited range which for current batteries does not exceed 80 km. Only little over 3000 electric vehicles were sold, a third of them to EDF. The natural gas is rather pure a fuel at burning of which the release of sulfur and solid particles are practically negligible. Due to its characteristics, the short and medium term development of this alternative seems to reside only in buses and service vehicles, the only able to support the supplementary load of high pressure gas tanks. Being formed of liquefied butane and propane at low pressure, LPG is as attractive as NG, with respect to the

    three primary drivers of sustainability of the water supply: demand, recharge, and sea level rise. We then determined the secondary drivers shaping the primary drivers and separated them into two groups: policy-relevant drivers and external drivers. We developed a simple water balance model to calculate maximum sustainable yield based on soil properties, land cover, daily precipitation and temperature. To identify critical scenarios, the model was run over the full forecasted ranges of external drivers, such as temperature, precipitation, sea level, and population. Only the status quo of the policy drivers such as land use, water use per capita, and habitat protection has been modeled to date. However, our next steps include working with stakeholders to elicit policy strategies such as conservation regulations or zoning plans, and testing the robustness of proposed strategies with the model developed.

We employ unique longitudinal traffic offense data and exploit the introduction of a point-recording scheme in Denmark. We....... In contrast, a stricter traffic punishment that conditionally suspends the driving license seems to have significant short-run and long-run effects. Our investigation into the types of offenses suggests that the deterrence effects are specific to the offense type for which they are imposed rather than generic...... improvements in driving behavior. These results imply that the effects of some of the existing traffic punishments are not only short-lived but also provide “specific deterrence”....

    Flexible Alternating Current Transmission Systems (FACTS) devices are installed on electric power transmission lines to stabilize and regulate power flow. Power lines protected by FACTS devices can increase power flow and better respond to contingencies. The University of Missouri Rolla (UMR) is currently working on a multi-year project to examine the potential use of multiple FACTS devices distributed over a large power system region in a cooperative arrangement in which the FACTS devices work together to optimize and stabilize the regional power system. The report describes operational and security challenges that need to be addressed to employ FACTS devices in this way and recommends references, processes, technologies, and policies to address these challenges.

    It is feasible for EU member states to meet their commitments regarding transport fuels under the Renewable Energy Directive (RED) and the Fuel Quality Directive (FQD) without resorting to biofuels from food crops. The RED target (10% renewable transport energy in 2020) can be met by a mix of measures aimed at improving energy efficiency, combined with a strong focus on growth of renewable electricity use and biofuels and biomethane from waste and residues. These measures also contribute to the FQD target (6% reduction in carbon intensity of fuels by 2020), but will need to be complemented by other measures such as reduced flaring and venting during oil production. The report shows how EU transport energy policy could reduce its reliance on biofuels from food crops that are likely to cause land use change. This alternative vision for the transport sector in 2020 would cut CO2 emissions by 205 million tonnes.

    Prisoners in South Africa face problems of overcrowding, violence and poor nutrition. Added to this burden in recent times is the increased threat from HIV. The HIV epidemic has been relatively late in coming to South Africa but infection rates are now 20% in the adult population. However, there is no data available on the level of HIV infection in the prison population. Overseas studies suggest that the characteristics of prisoners place them at much greater risk of HIV infection. Factors which contribute to increased levels of HIV infection include poor health care facilities, lack of condoms and lack of disinfectants. Current policies and practices on HIV in prison attempt to balance the constraints of limited resources with the need to preserve prisoner human rights. The outcomes include: mass testing not freely available, HIV education is limited, and early release of prisoners with advanced AIDS is not allowed. Constraints on the implementation of effective HIV prevention strategies include: bureaucratic inefficiency, lack of resources, and a reluctance by prison authorities to address the issue of HIV in prison. These problems can possibly be overcome by addressing the issue from both management and prisoner perspectives. On the management side, increased resources, increased training of prison officials, and increased political commitment to address the issue are required. Outside partnerships are probably required for an effective response. Prisoners require better nutrition, better living conditions, better health care, freely available condoms and disinfectants.

    Full Text Available An important challenge of the environmental policy is conceivingappropriate economic instruments able to account for the positive externalities provided by forest ecosystems. This issue is extremely important for implementing the provisions of the Romanian Forest Act, which states that forest owners shall be compensated for the opportunity costs of giving up harvesting operations due to various conservation purposes. The paper presents a statistical method based on analytical assessment of the effective forgone revenues brought about by banning the harvesting operations in 96 cases, each case being a distinctive forest management plan conceived for a large forest area, i.e. a production unit. Doing so, the scale effect has been taken into account because all legal provisions referring to forest management planning systems are focused on production units, considered the basic reference elements for sustainable forest management. The multiple regression function produced by the statistical analysis was turned into a simple formula allowing for a straightforward set up of the average compensation worth being paid per year and hectare. In order to better fetch the real opportunity cost paid for each hectare of protected forest, the algorithmwas further improved in order to account for the differences in stumpage residual value. Actually, the average compensation is differentiated onto five categories of hauling distances, using the same algorithm used by the National Forest Administration for differentiating the average reservation price established at national level on the ground of full-cost method stumpage pricing system.

Little is known about the psychological consequences of alternative management policies for these women. We compared, over 30-months, psychosocial outcomes of two policies: cytological surveillance (repeat cervical cytology tests in primary care and a hospital-based colposcopy examination.Women attending for a routine cytology test within the UK NHS Cervical Screening Programmes were eligible to participate. 3399 women, aged 20-59 years, with low-grade abnormal cytology, were randomised to cytological surveillance (six-monthly tests; n = 1703 or initial colposcopy with biopsies and/or subsequent treatment based on colposcopic and histological findings (n = 1696.

Twenty years ago, when Congress adopted the Nuclear Waste Policy Act of 1982 (NWPA or ''the Act''), it recognized the overwhelming consensus in the scientific community that the best option for such a facility would be a deep underground repository. Fifteen years ago, Congress directed the Secretary of Energy to investigate and recommend to the President whether such a repository could be located safely at Yucca Mountain, Nevada. Since then, our country has spent billions of dollars and millions of hours of research endeavoring to answer this question. I have carefully reviewed the product of this study. In my judgment, it constitutes sound science and shows that a safe repository can be sited there. I also believe that compelling national interests counsel in favor of proceeding with this project. Accordingly, consistent with my responsibilities under the NWPA, today I am recommending that Yucca Mountain be developed as the site for an underground repository for spent fuel and other radioactive wastes. The first consideration in my decision was whether the Yucca Mountain site will safeguard the health and safety of the people, in Nevada and across the country, and will be effective in containing at minimum risk the material it is designed to hold. Substantial evidence shows that it will. Yucca Mountain is far and away the most thoroughly researched site of its kind in the world. It is a geologically stable site, in a closed groundwater basin, isolated on thousands of acres of Federal land, and farther from any metropolitan area than the great majority of less secure, temporary nuclear waste storage sites that exist in the country today.

    2017-12-01

    China's remarkable progress in building a comprehensive social health insurance (SHI) system was swift and impressive. Yet the country's decentralized and incremental approach towards universal coverage has created a fragmented SHI system under which a series of structural deficiencies have emerged with negative impacts. First, contingent on local conditions and financing capacity, benefit packages vary considerably across schemes, leading to systematic inequity. Second, the existence of multiple schemes, complicated by massive migration, has resulted in weak portability of SHI, creating further barriers to access. Third, many individuals are enrolled on multiple schemes, which causes inefficient use of government subsidies. Moral hazard and adverse selection are not effectively managed. The Chinese government announced its blueprint for integrating the urban and rural resident schemes in early 2016, paving the way for the ultimate consolidation of all SHI schemes and equal benefits for all. This article proposes three policy alternatives to inform the consolidation: (1) a single-pool system at the prefectural level with significant government subsidies, (2) a dual-pool system at the prefectural level with risk-equalization mechanisms, and (3) a household approach without merging existing pools. Vertical integration to the provincial level is unlikely to happen in the near future. Two caveats are raised to inform this transition towards universal health coverage.

    Aim: During the past decade stress-echocardiography has gained increasing popularity for detection of myocardial ischemia in patients with coronary artery disease. However, about 10% to 15% of the patients submitted for stress-echocardiography do not have an adequate acoustic window. The purpose of this study was to compare high-dose dobutamine-stress magnetic resonance imaging (dobutamine-MRI) with dipyridamole-Tl-201-SPECT (dipyridamole-SPECT) as alternative strategies for detection of myocardial ischemia in patients with inadequate image quality by stress-echocardiography. Patients and Methods: Of 296 patients which were consecutively submitted to stress-echo-cardiography 45 patients (15%) had two or more segments that could not be evaluated according to the 16-segment-model of the American Society of Echocardiography. They underwent dobutamine-MRI and dipyridamole-SPECT studies, which were evaluated using a 28-segment modell. Myocardial segments were attributed to perfusion territories of the coronary arteries. The results of ischemia detection were compared to the results of coronary angiography (stenosis ≥50%). Results: In comparison to coronary angiography dobutamine-MRI yielded a sensitivity of 87%, a specificity of 86%, a positive predictive value of 93%, a negative predictive value of 75% and a diagnostic accuracy of 86%. For dipyridamole-SPECT results were 90%, 86%, 93%, 80% and 89%, respectively. These values were not significantly different. Conclusions: In patients not suitable for stress-echocardiography, both dobutamine-MRI and dipyridamole-SPECT are reliable strategies for detection of myocardial ischemia. Selection is dependent on the patient criteria, technical considerations, local logistics and experience of the observer. (orig.) [de

    At the request of its member countries, the OECD Nuclear Energy Agency (NEA) has become involved in global efforts to ensure a reliable supply of molybdenum-99 ({sup 99}Mo) and its decay product, technetium-99m ({sup 99m}Tc), the most widely used medical radioisotope. The NEA established the High-level Group on the Security of Supply of Medical Radioisotopes (HLG-MR). The main objective of the HLG-MR is to strengthen the reliability of {sup 99}Mo and {sup 99m}Tc supply in the short, medium and long term. In order to reach this objective, the group has been reviewing the {sup 99}Mo supply chain, working to identify the key areas of vulnerability, the issues that need to be addressed and the mechanisms that could be used to help resolve them. The collective efforts of HLG-MR members and nuclear medicine stakeholders have allowed for a comprehensive assessment of the key areas of vulnerability in the supply chain and an identification of the issues that need to be addressed. As a result of the work undertaken to date, the NEA has released three reports under the new The Supply of Medical Radioisotopes series. These reports discuss the uneconomical situation of the supply chain, other vulnerabilities within the supply chain and alternative technologies to produce {sup 99}Mo/{sup 99m}Tc. From this work, the NEA Secretariat and the HLG-MR have started to develop the policy approach and recommendations for governments, industry and other stakeholders that will outline the foundation for ensuring the long-term supply of {sup 99}Mo/{sup 99m}Tc.

    2017-12-01

    Full Text Available Alternative energetics is an important component of the competitiveness and security of the national economy. Its rapid development over the past 10 years is caused by both the attempts of individual countries to maintain and strengthen their competitive advantage in the world markets and the efforts of international organizations (UN, IRENA, IEA to consolidate different stakeholders to achieve energy and fiscal security, protection of environment and improvement of climate conditions. The article is aimed at generalizing global trends in alternative energetics in the context of development of the State policy in the sphere of fiscal security. A brief overview of the latest trends in the alternative energetics development, most of which focus on identifying the basic sectoral trends, has been provided. However, the issues of fiscal security in the energy sector remain poorly researched, especially in terms of formation of the State policy, consolidating interests of different groups of stakeholders. It has been determined that in the developed countries a significant growth of alternative energetics is caused by the consistent State policy on creation of conditions for formation of effective branch markets and the solving of so-called energy trilemma.

    Since 2015, a major economic crisis in Brazil has led to increasing poverty and the implementation of long-term fiscal austerity measures that will substantially reduce expenditure on social welfare programmes as a percentage of the country's GDP over the next 20 years. The Bolsa Família Programme (BFP)-one of the largest conditional cash transfer programmes in the world-and the nationwide primary healthcare strategy (Estratégia Saúde da Família [ESF]) are affected by fiscal austerity, despite being among the policy interventions with the strongest estimated impact on child mortality in the country. We investigated how reduced coverage of the BFP and ESF-compared to an alternative scenario where the level of social protection under these programmes is maintained-may affect the under-five mortality rate (U5MR) and socioeconomic inequalities in child health in the country until 2030, the end date of the Sustainable Development Goals. We developed and validated a microsimulation model, creating a synthetic cohort of all 5,507 Brazilian municipalities for the period 2017-2030. This model was based on the longitudinal dataset and effect estimates from a previously published study that evaluated the effects of poverty, the BFP, and the ESF on child health. We forecast the economic crisis and the effect of reductions in BFP and ESF coverage due to current fiscal austerity on the U5MR, and compared this scenario with a scenario where these programmes maintain the levels of social protection by increasing or decreasing with the size of Brazil's vulnerable populations (policy response scenarios). We used fixed effects multivariate regression models including BFP and ESF coverage and accounting for secular trends, demographic and socioeconomic changes, and programme duration effects. With the maintenance of the levels of social protection provided by the BFP and ESF, in the most likely economic crisis scenario the U5MR is expected to be 8.57% (95% CI: 6.88%-10.24%) lower

    An estimated 1 of 3 Americans uses some form of complementary and alternative medicine (CAM), such as acupuncture, homeopathy, or herbal medicine. In 1995, the National Institutes of Health Office of Alternative Medicine convened an expert panel to examine the role of clinical practice guidelines in CAM. The panel concluded that CAM practices currently are unsuitable for the development of evidence-based practice guidelines, in part because of the lack of relevant outcomes data from well-designed clinical trials. Moreover, the notions of standardization and appropriateness, inherent in guideline development, face challenging methodologic problems when applied to CAM, which considers many different treatment practices appropriate and encourages highly individualized care. Due to different belief systems and divergent theories about the nature of health and illness, CAM disciplines have fundamental differences in how they define target conditions, causes of disease, interventions, and outcome measures of effectiveness. These differences are even more striking when compared with those used by Western medicine. The panel made a series of recommendations on strategies to strengthen the evidence base for future guideline development in CAM and to meet better the current information needs of clinicians, patients, and guideline developers who seek information about CAM treatments.

    Most of the power generated in Eastern Ontario comes from the fossil-fired Lennox Generating Station, plus nuclear power from the Darlington plant near Toronto. Limited local power generation is provided by small hydro plants on the Rideau River system. Ontario provincial policy has favoured the expansion of nuclear power, to the detriment of all other sources. This has resulted in billions of dollars invested in the Greater Toronto Area and western Ontario. Investors are now gaining interest in cost-competitive renewable energy sources as energy industries face greater competition and increased environmental regulation. However, investment in renewable energy sources is not happening because of slow implementation and poorly thought-out processes. The author emphasized that the success of future alternative energy policies lies in partnerships where interested parties can work mutually to effect policy and political change. The International Energy Agency has stated that in the past 5 years, prices for renewable energies have become cost competitive with fossil technologies, but a long-term strategy and policy framework is needed to ensure that the full potential of renewable energy is not bypassed. The changes that are underway within the energy sector should be led by new policies that reflect social, economic and environmental priorities. It was suggested that Canada should follow the example of the European Union and require that a specific percentage of generation must come from renewable energy sources. 4 refs.

    Minors' access to tobacco has become an important public health issue. Little is known, however, about the knowledge, attitudes, beliefs, and behavior toward access among executives from businesses that sell tobacco. This study examined access from the perspective of corporate and regional headquarters of retail chains and franchises that sell tobacco. A total of 148 U.S. companies with the largest overall retail sales volume that sold tobacco were asked to participate; 91 agreed. The sample included grocery stores, convenience stores, gas station mini-marts, liquor stores, and drug stores. Data revealed at least moderate support for policies limiting youth tobacco access. Although most companies reported having in place policies to prevent minors from purchasing tobacco, these policies did not seem intensive. In addition, executives underestimated the extent of youth access. We conclude that the time is right for passage of bold policies to protect young people from tobacco.

  11. Are vehicle travel reduction targets justified? Evaluating mobility management policy objectives such as targets to reduce VMT and increase use of alternative modes

    Litman, T.

    2009-09-17

    This article presented several reasons for reforming current transportation policies to include targets to reduce vehicle miles of travel (VMT) and encourage use of alternative modes such as walking, cycling or public transit. Demographic and economic trends are increasing the demand for alternative modes, and economic competitiveness will require increased efficiency. As such, a variety of integrated transportation and land use policy reforms are needed to prepare for the future. Mobility management strategies that reduce vehicle travel include efficient road and parking pricing; more flexible zoning codes; and ridesharing incentives. Most mobility management strategies help solve a variety of problems and provide many benefits, including congestion reduction, road and parking cost savings, consumer savings, traffic safety, improved mobility for non-drivers, energy conservation, emission reductions, efficient land development, and improved public fitness and health. Improvements to public transit, road and parking pricing, and commute trip reduction programs also tend to reduce urban-peak traffic. The article suggested that VMT reduction targets are the first step in implementing mobility management policies. Although automobile travel will not disappear, it will decrease compared with current planning practices. 55 refs., 8 tabs., 6 figs.

    The aim of this study was to describe the current state of home visit nursing services in the Korean context and to suggest future policy directions. First, the three home visit nursing services that have developed in Korea are compared using the analytic framework provided by Gilbert and Terrell in 2012. The framework is based on four dimensions of social welfare: users, services, source of funds, and service delivery process. Second, we perform a strength, weakness, opportunity, and threat analysis to suggest comprehensive and constructive home visit nursing service policies for the future. Specifically, we advocate the creation of an organization that steers the central government to operate an integrated management organization to distribute services and reduce redundancy for preventing the waste of both medical and state financial resources. This study also recommends the development of educational programs to improve the quality of services and service evaluation criteria for the objective assessment of those services. These policy guidelines may prove useful both for Korea and for other countries that intend to prepare or revise their home visit nursing service systems. © 2014 Wiley Periodicals, Inc.

    Agricultural suitability maps are a key input for land use zoning and projections of cropland expansion. Suitability assessments typically consider edaphic conditions, climate, crop characteristics, and sometimes incorporate accessibility to transportation and market infrastructure. However, correct weighting among these disparate factors is challenging, given rapid development of new crop varieties, irrigation, and road networks, as well as changing global demand for agricultural commodities. Here, we compared three independent assessments of cropland suitability to spatial and temporal dynamics of agricultural expansion in the Brazilian state of Mato Grosso during 2001 2012. We found that areas of recent cropland expansion identified using satellite data were generally designated as low to moderate suitability for rainfed crop production. Our analysis highlighted the abrupt nature of suitability boundaries, rather than smooth gradients of agricultural potential, with little additional cropland expansion beyond the extent of the flattest areas (0-2% slope). Satellite-based estimates of the interannual variability in the use of existing crop areas also provided an alternate means to assess suitability. On average, cropland areas in the Cerrado biome had higher utilization (84%) than croplands in the Amazon region of northern Mato Grosso (74%). Areas of more recent expansion had lower utilization than croplands established before 2002, providing empirical evidence for lower suitability or alternative management strategies (e.g., pasture soya rotations) for lands undergoing more recent land use transitions. This unplanted reserve constitutes a large area of potentially available cropland (PAC)without further expansion, within the management limits imposed for pest management and fallow cycles. Using two key constraints on future cropland expansion, slope and restrictions on further deforestation of Amazon or Cerrado vegetation, we found little available flat land for

    The Nuclear Waste Policy Act of 1982 requires that the Enviromental Impact Statement prepared for the recommendation of a repository site must consider three sites -- the one selected for the repository and at least two alternatives. All of these sites must have been characterized, and the Secretary of Energy must have made a preliminary determination that each is suitable for development as a repository. There is great disagreement about whether that ''preliminary determination of suitability'' is to be made before or after site characterization. If the Act is interpreted as requiring the determination to be made after characterization is completed, DOE cannot recommend the first site for licensing until it has three sites that appear suitable after full characterization; if the determination can be made before characterization, DOE can proceed to licensing even if only one site survives characterization. While DOE plans to make the preliminary determination before starting characterization, the uncertainty about how a court might ultimately interpret the Act injects a significant institutional uncertainty into the schedule for the repository, and complicates contingency planning for the siting process. Early resolution of the interpretation would greatly aid DOE's planning for the siting program

    If a society decides to make use of the advantages of technologies that at the same time bear extensive potentials of harm, society has to prevent abuse of these potentials. Physical protection and other security measures inevitably entail a curtailment of personal liberty. The civil rights will not provide sufficient protection against such creeping loss of personal freedom. The high priority of the objects of legal protection in question will make it necessary to specify the civil rights according to conditions if the security measures are to become effective in practice. Weighing the legal merits and the principle of reasonableness will be the main instruments that will pave the way for a camouflaged change of legal concepts and, finally, a factual restriction of civil rights. Any policy of law intended to protect the civil rights therefore will have to clain responsible participation in research activities, technological development, and energy policy. The policy of law has to take care that the criterion of compatibility with the constitution, the weakening or strengthening effect of a technological system on the civil rights, will duly be taken into account in the process of democratic technology steering, and as early as possible.

    A collection of essays were presented to address the issue of rising oil and gas prices. This issue has significant social and environmental implications and the public wants to know what is driving prices up and who is profiting. The myth that gas taxes are driving price increases was dispelled. It was argued that price hikes are mainly due to crude oil price increases and to refining and marketing price increases. The link between rising prices and free trade was also emphasized. The North American Free Trade Agreement (NAFTA) tied Canada into a North American energy market in which U.S. demand sets prices in Canada. It was suggested that trade rules regarding energy should be changed. Other short and longer-term progressive policy alternatives were also presented in the second part of this report. One possible short-term policy response would be to tax windfall oil and gas profits and direct the resulting revenues to rebates for low-income households and for energy conservation initiatives. It was noted that the environmental benefit of rising prices is that it encourages conservation and improved fuel efficiency. The final part of this report discussed the issue of protecting electricity from deregulation and sited lessons learned from the deregulation of natural gas. 2 tabs., 4 figs

    Water Management in the U.S. Southwest is under increasing scrutiny as many areas endure persistent drought. The impact of these prolonged dry conditions is a product of regional climate and hydrological conditions, but also of a highly engineered water management infrastructure and a complex web of social arrangements whereby water is allocated, shared, exchanged, used, re-used, and finally consumed. We coupled an agent-based model with a regional hydrological model to understand the dynamics in one richly studied and highly populous area: southern Arizona, U.S.A., including metropolitan Phoenix and Tucson. There, multiple management entities representing an array of municipalities and other water providers and customers, including private companies and Native American tribes are enmeshed in a complex legal and economic context in which water is bought, leased, banked, and exchanged in a variety of ways and on multiple temporal and physical scales. A recurrent question in the literature of adaptive management is the impact of management structure on overall system performance. To explore this, we constructed an agent-based model to capture this social complexity, and coupled this with a physical hydrological model that we used to drive the system under a variety of water stress scenarios and to assess the regional impact of the social system's performance. We report the outcomes of ensembles of runs in which varieties of alternative policy constraints and management strategies are considered. We hope to contribute to policy discussions in this area and connected and legislatively similar areas (such as California) as current conditions change and existing legal and policy structures are revised. Additionally, we comment on the challenges of integrating models that ostensibly are in different domains (physical and social) but that independently represent a system in which physical processes and human actions are closely intertwined and difficult to disentangle.

    Commercial electric power generation, nuclear weapons production, the operation of naval reactors, and research and development activities produce spent nuclear fuel and high-level radioactive waste. Spent nuclear fuel and high-level radioactive waste have been accumulating at commercial reactor sites and storage facilities across the country since 1957. Spent nuclear fuel and high-level radioactive waste have been accumulating at sites now managed by U.S. Department of Energy (DOE) since the mid-1940s. The DOE has the statutory obligation to dispose of these wastes. The U.S. has studied methods for the safe storage and disposal of radioactive waste for more than 40 years. Many organizations and government agencies have participated in these studies. In the 1950s, the U.S. Atomic Energy Commission requested the National Academy of Sciences to evaluate options for land disposal of radioactive waste. The U.S. Atomic Energy Commission and its successor agencies, the Energy Research and Development Administration and the DOE, continued to analyze radioactive waste management options throughout the 1960s and 1970s. In 1979, an Interagency Review Group that included representatives of 14 federal government entities provided findings and recommendations to the President. After analyzing a range of options, disposal in a geologic repository emerged as the preferred long-term environmental solution. This consensus is reflected in the Nuclear Waste Policy Act of 1982 (NWPA). The NWPA and related statutes established the framework for addressing the issues of radioactive waste disposal and designated the roles and responsibilities of the federal government and the owners and generators of the waste

  5. LNG as a marine and inland waterway fuel. Contribution of AFG (French gas association) to the national policy framework for the deployment of alternative fuel infrastructures (AFNPF)

    International Nuclear Information System (INIS)

    2016-06-01

    Here in the early 21. Century, the environmental footprint of marine and inland waterway transport is a major concern on a global scale. Under the authority of the International Maritime Organisation (IMO), regulations on atmospheric emissions are becoming increasingly tighter. The European Union (EU) is deeply committed to this endeavour and in particular has adopted Directive 2014/94/EU which aims to facilitate the deployment of an alternative fuels infrastructure. The Directive calls upon Member States to develop by 18 November 2016, national policy frameworks for the deployment of alternative fuel infrastructures (AFNPF) that must designate an appropriate number of LNG refuelling points in maritime and inland ports for maritime and inland waterway transport purposes. In light of this, the French Gas Association (AFG), in cooperation with all affected stakeholders and interested parties, has discussed the role of LNG as a marine and inland waterway fuel in the energy transition toward green growth, in order to contribute to the development of France's 'national policy framework' (AFNPF) under the Directive mentioned above. To assess the prospects of the LNG bunkering market in France, as well as the implementation of the corresponding infrastructures, the AFG adopted a scenario-based approach from the user's perspective. Considering that we are in an early stage, the study focuses on the types of ships that are most likely to use LNG, and it examines their traffic in France's major metropolitan ports, along with forecasted activity based on the strategic plans for those ports. Two scenarios - one being rather conservative (baseline) and the other being more optimistic - were examined over three timelines: 2020, 2025 and 2030. The scenarios lead to a gradual implementation of LNG fuel in French ports, on the three coastlines and along the five inland waterway corridors. They show LNG fuel needs in all the ports of the central TEN

    A strain of Fusarium oxysporum fungus is killing coca plants in the Chapare coca growing region of Bolivia. Coca farmers are already constrained in the amount of coca they can grow under the government's community-based coca control approach, "social control." Coca leaf is the main ingredient in cocaine, but it is also a traditional medicine and food, is economically vital to household incomes, and is a political symbol of the current government administration. Bolivia's approach to coca control, now administered without any United States military intervention, is an innovative example of experimentation with drug policy reform. This paper is based on ethnographic research including semi-structured interviews and observation. Coca growers are worried about the dire economic, social, and political consequences of the fungus' appearance and spread since summer 2013. They have two explanations for its origins: First, that it was sent by the United States government, which in the past was developing a strain of F. oxysporum for use in the drug war; Second, and the explanation of scientists, is that the outbreak is caused by the overuse of agrochemicals and other intensive agricultural practices. More than a matter of agroecology, the practices identified in the second explanation must be understood in terms of the persistence of the international drug prohibition regime. Bolivia's social control approach is a successful alternative to violent eradication measures, however the country is constrained to uphold the fundamental principles of supply-side control in order to be a respected partner in global drug control. The supply-side logics restricting social control make intensive agriculture practices attractive, but may have contributed to the fungus' proliferation and its continued spread. The fungus draws attention to the challenges of policy reform, new collateral damages of drug control, and role environmental factors can play in drug control politics. Copyright

    According to the Energy Information Administration (EIA) of the U.S. Department of Energy (DOE), geothermal energy generation in the United States is projected to more than triple by 2040 (EIA 2013). This addition, which translates to more than 5 GW of generation capacity, is anticipated because of technological advances and an increase in available sources through the continued development of enhanced geothermal systems (EGSs) and low-temperature resources (EIA 2013). Studies have shown that air emissions, water consumption, and land use for geothermal electricity generation have less of an impact than traditional fossil fuel–based electricity generation; however, the long-term sustainability of geothermal power plants can be affected by insufficient replacement of aboveground or belowground operational fluid losses resulting from normal operations (Schroeder et al. 2014). Thus, access to water is therefore critical for increased deployment of EGS technologies and, therefore, growth of the geothermal sector. This paper examines water issues relating to EGS development from a variety of perspectives. It starts by exploring the relationship between EGS site geology, stimulation protocols, and below ground water loss, which is one of the largest drivers of water consumption for EGS projects. It then examines the relative costs of different potential traditional and alternative water sources for EGS. Finally it summarizes specific state policies relevant to the use of alternative water sources for EGS, and finally explores the relationship between EGS site geology, stimulation protocols, and below ground water loss, which is one of the largest drivers of water consumption for EGS projects.

    The designated successor to fossil fuels is nuclear fission/fusion and that turns out to be problematic. Alternative Energy Systems have great potential but political forces seem to be hampering their development and introduction. The technologies are flexible in their use and scale of operation. The learning curve will not be short but neither will it be as long and as costly as nuclear power. It is time that this is recognised and some serious rethinking takes place in what presently passes for energy policies both in the industrialised countries and in the Third World. Alternative energy systems are defined and some of them which are relevant to the United Kingdom are discussed. (author)

    Tsita, Katerina G.; Pilavachi, Petros A.

    2012-01-01

    This paper evaluates alternative fuels for the Greek road transport sector, using the Analytic Hierarchy Process. Seven different alternatives of fuel mode are considered in this paper: internal combustion engine (ICE) and its combination with petroleum and 1st and 2nd generation biofuels blends, fuel cells, hybrid vehicles, plug-in hybrids and electric vehicles. The evaluation of alternative fuel modes is performed according to cost and policy aspects. In order to evaluate each alternative fuel, one base scenario and ten alternative scenarios with different weight factors selection per criterion are presented. After deciding the alternative fuels’ scoring against each criterion and the criteria weights, their synthesis gives the overall score and ranking for all ten alternative scenarios. It is concluded that ICE blended with 1st and 2nd generation biofuels are the most suitable alternative fuels for the Greek road transport sector. - Highlights: ► Alternative fuels for the Greek road transport sector have been evaluated. ► The method of the AHP was used. ► Seven different alternatives of fuel mode are considered. ► The evaluation is performed according to cost and policy aspects. ► The ICE with 1st and 2nd generation biofuels are the most suitable fuels.

    The Yarmouk River, the main tributary to the Jordan River, is shared but not jointly managed by three countries: Syria, Jordan and Israel. Political distrust and conflicts mean that the equitable sharing of its waters has never materialized despite the signature of bilateral agreements. This state of affairs culminated in the 90ies and led to a rapid change in the flow regime of the Yarmouk River, where both peak and base flows almost disappeared at the turn of the millennium. Jordan blames Syria for building more dams than agreed on in 1987, while Syria blames Israel for doing the same in the Golan Heights. Even though less water is available for downstream Jordan and Israel, these two countries keep exchanging water, following updated rules since the 1994 Peace Treaty. While both literature and stakeholders in the region concur that most freshwater resources are consumed in Syria, there is actually no study that tracks agricultural and storage changes, both legal and illegal, in the Yarmouk basin in relation to the flow regime. This exercise is compounded by unavailability of information on water uses due to the long-standing lack of cooperation in the region, an issue exacerbated more recently by the ongoing civil war in Syria. Using a modeling framework based on remote sensing and a multi-agent simulation model, changes in the Yarmouk River flow regime are explained for three different development stages corresponding to the years 1984, 1998 and 2014. Landsat images, coupled with the analysis of land surface temperature, made possible the distinction of rainfed and irrigated crops, as well as the estimation of reservoirs' storage. For each stage, the impact on downstream riparian countries is assessed using a simulation model of the Israel-Jordan Peace Treaty. Other scenarios are also analyzed to assess the effectiveness of alternative policy and cooperation scenarios including water demand management measures in Syria, the reoperation of illegal reservoirs and

    2015-06-01

    Full Text Available Climate change is putting infrastructure, food supply, water resources, ecosystems, and human health at risk. These risks will be exacerbated depending on the degree of additional greenhouse gas emissions. Urgent action is needed to limit the severity of impacts associated with further warming. British Columbia (BC has taken action to reduce greenhouse gas emissions from carbon-based fuels by introducing a carbon tax in 2008. As an innovative approach to climate change mitigation, especially in North America, studies evaluating its effectiveness are valuable. We assessed the long-term viability potential of the BC carbon tax using common pool resource design principles, a novel application of the design principles to environmental policy. We found that the design principles can be applied productively to environmental policy and larger scale air pollution problems. With regard to the BC carbon tax, our findings suggest that closer monitoring of user behavior, further increases of the tax over time, and pursuing efforts for a more elaborate system of nested enterprises and interjurisdictional cooperation could increase the long-term success of the BC carbon tax. We also found that the design principles allowed us to more comprehensively reach conclusions regarding the broader effectiveness of the tax when compared to existing policy analysis. Traditionally, climate policy evaluation has focused on the end goal without considering broader constraints and issues of resource allocation. We suggest that common pool resource theory, which is based on strong theoretical principles and encourages reflexivity, will be able to address those limitations.

  3. Alternative additives; Alternative additiver

    Energy Technology Data Exchange (ETDEWEB)

    2007-08-15

    In this project a number of industrial and agricultural waste products have been characterised and evaluated in terms of alkali-getter performance. The intended use is for biomass-fired power stations aiming at reducing corrosion or slagging related problems. The following products have been obtained, characterised and evaluated: 1) Brewery draff 2) Danish de-gassed manure 3) Paper sludge 4) Moulding sand 5) Spent bleaching earth 6) Anorthosite 7) Sand 8) Clay-sludge. Most of the above alternative additive candidates are deemed unsuitable due to insufficient chemical effect and/or expensive requirements for pre-treatment (such as drying and transportation). 3 products were selected for full-scale testing: de-gassed manure, spent bleaching earth and clay slugde. The full scale tests were undertaken at the biomass-fired power stations in Koege, Slagelse and Ensted. Spent bleaching earth (SBE) and clay sludge were the only tested additive candidates that had a proven ability to react with KCl, to thereby reduce Cl-concentrations in deposits, and reduce the deposit flux to superheater tubes. Their performance was shown to nearly as good as commercial additives. De-gassed manure, however, did not evaluate positively due to inhibiting effects of Ca in the manure. Furthermore, de-gassed manure has a high concentration of heavy metals, which imposes a financial burden with regard to proper disposal of the ash by-products. Clay-sludge is a wet clay slurring, and drying and transportation of this product entails substantial costs. Spent bleaching does not require much pre-treatment and is therefore the most promising alternative additive. On the other hand, bleaching earth contains residual plant oil which means that a range of legislation relating to waste combustion comes into play. Not least a waste combustion fee of 330 DKK/tonne. For all alternative (and commercial) additives disposal costs of the increase ash by-products represents a significant cost. This is

  4. Incentive policies for promoting wind power production in Brazil: Scenarios for the Alternative Energy Sources Incentive Program (PROINFA) under the New Brazilian electric power sector regulation

    International Nuclear Information System (INIS)

    Dutra, Ricardo Marques; Szklo, Alexandre Salem

    2008-01-01

    The Alternative Energy Sources Incentive Program (PROINFA) was designed in 2002 to stimulate the electricity generation from three energy sources (wind, biomass and small-scale hydro) in Brazil. The Program was divided into two phases. The first one uses feed-in tariffs for promoting the development of 3300 MW. The second one that was originally based on feed-in tariffs was modified in 2003, in order to be based on biddings for renewables. These biddings are capped to limit their impact on the final electricity tariff. Due to this bound, the highest-cost power option promoted by PROINFA (wind power generation) might have development problems. Simulating different scenarios for the biddings, it was verified that the only way to reach the original goal set by PROINFA (10% of the annual electricity consumption provided by alternative sources up to 2020) and, simultaneously, not overcome the bidding bound is to promote biomass-fired power generation alone, during the Program's second phase. However, this action contradicts one of the targets of the Program, which is to diversify the energy matrix. An alternative option could be biddings for renewables according to specific criteria (complementarities, industrial and technological development and cost), based not only on their cost-effectiveness.

  5. Suitable footwear for enhanced safety

    2004-01-01

    Safety shoes are the theme of a new safety campaign. Always remember that accidents can happen - even to your feet! When entering hazardous areas such as underground halls, work sites, experiment assembly sites, workshops etc., sandals, ordinary shoes or similar light footwear should not be worn. Whatever the risks to which you may be exposed, always think safety and wear suitable footwear, i.e. safety shoes, which have non-slip soles and steel reinforcements to protect your feet from being crushed, fractured or pierced. Is it serious, Doctor? "Some traumas resulting from foot-related accidents - open fractures for instance - can be quite serious," explains CERN Works Doctor Véronique Fassnacht. "But the most common injuries are sprained ankles sustained during simple falls caused by differences in floor-levels (e.g. false floors). Fractures, bruising, surface wounds or deep wounds caused by objects falling onto the top of the foot are also quite common." ...

    Variant Creutzfeldt-Jakob disease (vCJD) has been transmitted by blood transfusion (TTvCJD). The US Food and Drug Administration (FDA) recommends deferring blood donors who resided in or traveled to 30 European countries where they may have been exposed to bovine spongiform encephalopathy (BSE) through beef consumption. Those recommendations warrant re-evaluation, because new cases of BSE and vCJD have markedly abated. The FDA developed a risk-ranking model to calculate the geographic vCJD risk using country-specific case rates and person-years of exposure of US blood donors. We used the reported country vCJD case rates, when available, or imputed vCJD case rates from reported BSE and UK beef exports during the risk period. We estimated the risk reduction and donor loss should the deferral be restricted to a few high-risk countries. We also estimated additional risk reduction by leukocyte reduction (LR) of red blood cells (RBCs). The United Kingdom, Ireland, and France had the greatest vCJD risk, contributing approximately 95% of the total risk. The model estimated that deferring US donors who spent extended periods of time in these three countries, combined with currently voluntary LR (95% of RBC units), would reduce the vCJD risk by 89.3%, a reduction similar to that achieved under the current policy (89.8%). Limiting deferrals to exposure in these three countries would potentially allow donations from an additional 100,000 donors who are currently deferred. Our analysis suggests that a deferral option focusing on the three highest risk countries would achieve a level of blood safety similar to that achieved by the current policy. © 2016 AABB.

    Full Text Available This paper addresses the comparative analysis of discrete institutional alternatives in organizing transactions among distinct economic entities. The theoretical framework for understanding this issue was introduced by Ronald Coase 80 years ago. Following this seminal contribution, a standard theoretical distinction now exists between the institutionally embedded set of economic exchanges (the transactions and the institutional settings within which these transactions are organized, firms and markets being the epitomized polar cases. On the normative side, this approach facilitated better understanding of failures and flaws in the organization of numerous transactions and of how to fix them. Three examples are provided to illustrate the issues at stake: contracting on large diameter pipes for PJSC “Gazprom” infrastructure projects, contracting in commercial real estate, and determining governance mechanisms for companies facing significant switching costs in highly concentrated markets.

    2008-01-01

    Energy policy objectives and the suitability of traditional instruments to achieve them are currently under review. The main goals are to improve the balance among the three priorities of energy policy-making, to make a transition to both a more sustainable energy mix and, at the same time, improve the security of that mix during the transition to it. As this policy will only produce result in the longer term, an alternative in EU external energy policy-making should be found to coercing reluctant members states into accepting the usually top down, generic approach of the EU and into giving up competencies that serve national interests. This pragmatic route to policy-making could be to explore a path that turns EU weakness in the foreign and energy policy sphere into strengths by the smart use of diversity, asymmetry and subsidiarity in a bottom up, more tailor-made approach

    International Nuclear Information System (INIS)

    Kocoloski, Matthew; Griffin, W Michael; Matthews, H Scott

    2009-01-01

    Biofuel debates often focus heavily on carbon emissions, with parties arguing for (or against) biofuels solely on the basis of whether the greenhouse gas emissions of biofuels are less than (or greater than) those of gasoline. Recent studies argue that land use change leads to significant greenhouse gas emissions, making some biofuels more carbon intensive than gasoline. We argue that evaluating the suitability and utility of biofuels or any alternative energy source within the limited framework of plus and minus carbon emissions is too narrow an approach. Biofuels have numerous impacts, and policy makers should seek compromises rather than relying solely on carbon emissions to determine policy. Here, we estimate that cellulosic ethanol, despite having potentially higher life cycle CO 2 emissions (including from land use) than gasoline, would still be cost-effective at a CO 2 price of $80 per ton or less, well above estimated CO 2 mitigation costs for many alternatives. As an example of the broader approach to biofuel policy, we suggest the possibility of using the potential cost reductions of cellulosic ethanol relative to gasoline to balance out additional carbon emissions resulting from indirect land use change as an example of ways in which policies could be used to arrive at workable solutions.

    Shang, Ning; Weng, Chunhua; Hripcsak, George

    2017-09-08

    To contribute a conceptual framework for evaluating data suitability to satisfy the research needs of observational studies. Suitability considerations were derived from a systematic literature review on researchers' common data needs in observational studies and a scoping review on frequent clinical database design considerations, and were harmonized to construct a suitability conceptual framework using a bottom-up approach. The relationships among the suitability categories are explored from the perspective of 4 facets of data: intrinsic, contextual, representational, and accessible. A web-based national survey of domain experts was conducted to validate the framework. Data suitability for observational studies hinges on the following key categories: Explicitness of Policy and Data Governance, Relevance, Availability of Descriptive Metadata and Provenance Documentation, Usability, and Quality. We describe 16 measures and 33 sub-measures. The survey uncovered the relevance of all categories, with a 5-point Likert importance score of 3.9 ± 1.0 for Explicitness of Policy and Data Governance, 4.1 ± 1.0 for Relevance, 3.9 ± 0.9 for Availability of Descriptive Metadata and Provenance Documentation, 4.2 ± 1.0 for Usability, and 4.0 ± 0.9 for Quality. The suitability framework evaluates a clinical data source's fitness for research use. Its construction reflects both researchers' points of view and data custodians' design features. The feedback from domain experts rated Usability, Relevance, and Quality categories as the most important considerations. © The Author 2017.

    2010-08-01

    By applying the theories of ecological suitability and the methods of fuzzy mathematics, this paper established a climatic suitability model for citrus, calculated and evaluated the climatic suitability and its spatiotemporal differences for citrus production in subtropical China, and analyzed the climatic suitability of citrus at its different growth stages and the mean climatic suitability of citrus in different regions of subtropical China. The results showed that the citrus in subtropical China had a lower climatic suitability and a higher risk at its flower bud differentiation stage, budding stage, and fruit maturity stage, but a higher climatic suitability and a lower risk at other growth stages. Cold damage and summer drought were the key issues affecting the citrus production in subtropical China. The citrus temperature suitability represented a latitudinal zonal pattern, i. e., decreased with increasing latitude; its precipitation suitability was high in the line of "Sheyang-Napo", medium in the southeast of the line, low in the northwest of the line, and non in high mountainous area; while the sunlight suitability was in line with the actual duration of sunshine, namely, higher in high-latitude areas than in low-latitude areas, and higher in high-altitude areas than in plain areas. Limited by temperature factor, the climatic suitability was in accordance with temperature suitability, i. e., south parts had a higher suitability than north parts, basically representing latitudinal zonal pattern. From the analysis of the inter-annual changes of citrus climatic suitability, it could be seen that the citrus climatic suitability in subtropical China was decreasing, and had obvious regional differences, suggesting that climate change could bring about the changes in the regions suitable for citrus production and in the key stages of citrus growth.

    The purpose of this document is to discuss issues related to the implementation of each of the five down-selected INEEL/INTEC radioactive liquid waste (sodium-bearing waste - SBW) treatment alternatives and summarize information in three main areas of concern: process/technical, environmental permitting, and schedule. Major implementation options for each treatment alternative are also identified and briefly discussed. This report may touch upon, but purposely does not address in detail, issues that are programmatic in nature. Examples of these include how the SBW will be classified with respect to the Nuclear Waste Policy Act (NWPA), status of Waste Isolation Pilot Plant (WIPP) permits and waste storage availability, available funding for implementation, stakeholder issues, and State of Idaho Settlement Agreement milestones. It is assumed in this report that the SBW would be classified as a transuranic (TRU) waste suitable for disposal at WIPP, located in New Mexico, after appropriate treatment to meet transportation requirements and waste acceptance criteria (WAC).

    The suitability of geoenvironment for waste disposal depends mainly on its stability and on the danger of groundwater pollution. Besides them, on the land suitability maps for the given purpose also those factors of the factors of the geoenvironment and the landscape should be taken into account, which enable another way of the land use, such as mineral resources, water resources, fertile soils, nature reserves, etc. On the base of the relevant factors influence evaluation - suitable, moderately suitable and unsuitable territorial units are delimited on the maps. The different way of various scale maps compilation is applied, taken into account their different representing feasibilities. (authors)

    The concept that alternative therapies can eliminate toxins and toxicants from the body, i.e. 'alternative detox' (AD) is popular. Selected textbooks and articles on the subject of AD. The principles of AD make no sense from a scientific perspective and there is no clinical evidence to support them. The promotion of AD treatments provides income for some entrepreneurs but has the potential to cause harm to patients and consumers. In alternative medicine, simplistic but incorrect concepts such as AD abound. AREAS TIMELY FOR RESEARCH: All therapeutic claims should be scientifically tested before being advertised-and AD cannot be an exception.

    Site selection for waste disposal is a complex task that should meet the requirements of communities and stakeholders. In this article, three decision support methods (Boolean logic, index overlay and fuzzy gamma) are used to perform land suitability analysis for landfill siting. The study was carried out in one of the biggest metropolitan regions of Italy, with the objective of locating suitable areas for waste disposal. Physical and socio-economic information criteria for site selection were decided by a multidisciplinary group of experts, according to state-of-the-art guidelines, national legislation and local normative on waste management. The geographic information systems (GIS) based models used in this study are easy to apply but require adequate selection of criteria and weights and a careful evaluation of the results. The methodology is arranged in three steps, reflecting the criteria defined by national legislation on waste management: definition of factors that exclude location of landfills or waste treatment plants; classification of the remaining areas in terms of suitability for landfilling; and evaluation of suitable sites in relation to preferential siting factors (such as the presence of quarries or dismissed plants). The results showed that more than 80% of the provincial territory falls within constraint areas and the remaining territory is suitable for waste disposal for 0.72% or 1.93%, according to the model. The larger and most suitable sites are located in peripheral areas of the metropolitan system. The proposed approach represents a low-cost and expeditious alternative to support the spatial decision-making process. © The Author(s) 2014.

    the travel range of large vans is an important barrier for electrification due to the battery weight and the limitation of 3.5 tonnes gross vehicle weight for driving with a normal driving licence. The rule needs amendments for electric vehicles, as has been done in Germany. The paper recommends EU countries......This paper identifies commercial sectors suitable for a shift to electric mobility. The paper concludes that the construction and the health care service sectors are the most suitable for electric mobility because many vehicles are registered in these sectors and daily mileage is reasonably low....... They should be primary target groups of specific policy measures to promote the use of electric vehicles. Denmark has only had a few incentives to promote the use of commercial electric vehicles. Until now electric vehicles do generally not show economic benefits unless travel distance is high. However, today...

  11. Less is more: Strategic scale site suitability for concentrated solar thermal power in Western Australia

    International Nuclear Information System (INIS)

    Dawson, Lucas; Schlyter, Peter

    2012-01-01

    Concentrated Solar Thermal Power (CSP) represents a technology with a great deal of promise for low-emissions electricity generation. Several recent studies have identified large swathes of the world’s ‘sunbelt’ as technically suitable for the technology, but current estimates grossly overestimate site suitability for CSP. There is a need for more realistic suitability estimations in order to provide a more accurate basis for policy and investment decisions. This paper establishes a generally applicable GIS-based methodology to better enable identification of CSP-suitable sites at the continental scale. We test the methodology, identifying a large number of CSP suitable sites in Western Australia (WA). Our results indicate a 99.4% reduction from technically suitable areas to areas showing medium-to-very-high suitability in the current and near term in WA. The availability of infrastructure is critical to site suitability and the introduction of new major loads and infrastructure in currently under-developed regions is likely to open up further areas with medium to very high suitability. Despite the fact that current global/continental scale estimates of CSP potentials are likely overestimated by at least two orders of magnitude, truly CSP-suitable areas remain more than sufficient to motivate investment in utility-scale CSP and power potentials from this technology remain enormous. - Highlights: ► 1.78 million km 2 of Western Australia is identified as technically suitable. ► Hypothetical production potential of technically suitable area ≈908,000 TW h/year. ► Only 0.6% of technically suitable areas considered to be medium-very highly suitable. ► Site suitability highly dependent on availability of infrastructure and load. ► Suitable areas still more than sufficient to motivate CSP production.

    In this document we compare the performance of the Amazon Web Services (AWS), also known as Amazon Cloud, with the CLARREO (Climate Absolute Radiance and Refractivity Observatory) cluster and assess its suitability for computational needs of the CLARREO mission. A benchmark executable to process one month and one year of PARASOL (Polarization and Anistropy of Reflectances for Atmospheric Sciences coupled with Observations from a Lidar) data was used. With the optimal AWS configuration, adequate data-processing times, comparable to the CLARREO cluster, were found. The assessment of alternatives to the CLARREO cluster continues and several options, such as a NASA-based cluster, are being considered.

    Golder Associates Inc. (GAI) has developed a probabilistic total system performance assessment and strategy evaluation model (RIP) which can be applied in an iterative manner to evaluate repository site suitability and guide site characterization. The major portion of the software is the performance assessment model, which consists of a series of coupled component models for radionuclide transfer. The performance model itself is embedded within a decision analysis model which allows the user to evaluate alternative site characterization strategies. This paper provides an overview of the methodology, and summarizes the basic concepts of RIP

    The information in the US ERDA ''Technical Alternatives Document'' is summarized. The first two points show that waste treatment, interim storage and transportation technologies for all wastes are currently available. Third, an assessment of integrated waste management systems is needed. One such assessment will be provided in our expanded waste management environmental statement currently planned for release in about one year. Fourth, geologies expected to be suitable for final geologic storage are known. Fifth, repository system assessment methods, that is a means to determine and assess the acceptability of a terminal storage facility for nonretrievable storage, must and will be prepared. Sixth, alternatives to geologic storage are not now available. Seventh, waste quantities and characteristics are sensitive to technologies and fuel-cycle modes, and therefore an assessment of these technologies and modes is important. Eighth, and most important, it is felt that the LWR fuel cycle can be closed with current technologies

  17. Land Suitability and Insurance Premiums: A GIS-based Multicriteria Analysis Approach for Sustainable Rice Production

    2018-05-01

    Full Text Available The purpose of this research is to develop a land suitability model for rice production based on suitability levels and to propose insurance premiums to obtain maximum returns based on the harvest index and subsidy dependence factor for the marginal and moderately suitable lands in the northern part of Bangladesh. A multicriteria analysis was undertaken and a rice land suitability map was developed using geographical information system and analytical hierarchy process. The analysis identified that 22.74% of the area was highly suitable, while 14.86% was marginally suitable, and 28.54% was moderately suitable for rice production. However, 32.67% of the area, which was occupied by water bodies, rivers, forests, and settlements, is permanently not suitable; 1.19% is presently not suitable. To motivate low-quality land owners to produce rice, there is no alternative but to provide protection through crop insurance. We suggest producing rice up to marginally suitable lands to obtain support from insurance. The minimum coverage is marginal coverage (70% to cover the production costs, while the maximum coverage is high coverage (90% to enable a maximum return. This new crop insurance model, based on land suitability can be a rational support for owners of different quality land to increase production.

    2009-04-01

    "Cosmologists are often in error but never in doubt." This pithy characterization by the Soviet physicist Lev Landau sums up the raison d'être of Facts and Speculations in Cosmology. Authors Jayant Narlikar and Geoffrey Burbidge are proponents of a "steady state" theory of cosmology, and they argue that the cosmological community has become fixated on a "Big Bang" dogma, suppressing alternative viewpoints. This book very much does what it says on the tin: it sets out what is known in cosmology, and puts forward the authors' point of view on an alternative to the Big Bang.

  6. Mapping grasslands suitable for cellulosic biofuels in the Greater Platte River Basin, United States

    Science.gov (United States)

    Wylie, Bruce K.; Gu, Yingxin

    2012-01-01

    Biofuels are an important component in the development of alternative energy supplies, which is needed to achieve national energy independence and security in the United States. The most common biofuel product today in the United States is corn-based ethanol; however, its development is limited because of concerns about global food shortages, livestock and food price increases, and water demand increases for irrigation and ethanol production. Corn-based ethanol also potentially contributes to soil erosion, and pesticides and fertilizers affect water quality. Studies indicate that future potential production of cellulosic ethanol is likely to be much greater than grain- or starch-based ethanol. As a result, economics and policy incentives could, in the near future, encourage expansion of cellulosic biofuels production from grasses, forest woody biomass, and agricultural and municipal wastes. If production expands, cultivation of cellulosic feedstock crops, such as switchgrass (Panicum virgatum L.) and miscanthus (Miscanthus species), is expected to increase dramatically. The main objective of this study is to identify grasslands in the Great Plains that are potentially suitable for cellulosic feedstock (such as switchgrass) production. Producing ethanol from noncropland holdings (such as grassland) will minimize the effects of biofuel developments on global food supplies. Our pilot study area is the Greater Platte River Basin, which includes a broad range of plant productivity from semiarid grasslands in the west to the fertile corn belt in the east. The Greater Platte River Basin was the subject of related U.S. Geological Survey (USGS) integrated research projects.

  7. The alternative energy future

    Spitzley, H.

    1989-02-01

    The alternative energy future can be achieved only by making energy conservation programmes successful, and by fully committing to the utilization of soft energy sources. This is the perspective drawn by the author who in this book investigates the fundamentals of an ecologically and socially sound energy policy for the future. Looking at California, USA, where completely near concepts have been put to work in the energy sector since the mid-seventies, the author shows how it can be done, by rewarding energy conserving activities, using available energy sources more efficiently, developing the means for renewable energy exploitation wherever appropriate. A turn in energy policy is feasible also in West Germany, both in technical and political terms. Starting from the experience gained in the USA, the author presents an outline of options and potentials of a new energy strategy for the Federal Republic of Germany. (orig./HP) [de

    The aim of the study was to assess the suitability of radiofrequency ablation (RFA), endovenous laser ablation (EVLA), and foam sclerotherapy (FS) for patients with symptomatic varicose veins (VVs). The study comprised 403 consecutive patients with symptomatic VVs. Data on 577 legs from 403 consecutive patients with symptomatic VVs were collected for the year 2006. Median patient age was 55 years (interquartile range 45-66), and 62% patients were women. A set of criteria based on duplex ultrasonography was used to select patients for each procedure. Great saphenous vein (GSV) reflux was present in 77% (446 of 577) of legs. Overall, 328 (73%) of the legs were suitable for at least one of the endovenous options. Of the 114 legs with recurrent GSV reflux disease, 83 (73%) were suitable to receive endovenous therapy. Patients with increasing age were less likely to be suitable for endovenous therapy (P = 0.03). Seventy-three percent of patients with VVs caused by GSV incompetence are suitable for endovenous therapy.

    Indonesian government currently has policies to improve the performance of the tourism sector, including marine tourism. One of the attractions of marine tourism is the coral ecosystem especially through scuba diving activities. The purpose of this study was to determine the suitability of the coral ecosystem on Saebus Island, East Java, to find appropriate locations for scuba diving activities. Purposive samplings were done around the island to determine four stations which will be assessed through suitability analysis. Tourism Suitability Index was used to assess all stations for scuba diving activities. The result showed that all four stations were categorized as very suitable with the score: 85%, 85%, 85% and 83%, respectively. Several aspects that need to be improved and anticipated for diving at all stations are coral coverage and water current. These results suggest that there are several spots around Saebus Island that are suitable for diving site, and can be promoted as marine tourism destination.

    Although eastern elk (Cervus elaphus canadensis) were extirpated from the eastern United States in the 19th century, they were successfully reintroduced in the North Carolina portion of the Great Smoky Mountains National Park in the early 2000s. The North Carolina Wildlife Resources Commission (NCWRC) is evaluating the prospect of reintroducing the species in other locations in the state to augment recreational opportunities. As a first step in the process, we created a state-wide elk habitat suitability map. We used medium-scale data sets and a two-component approach to iden- tify areas of high biological value for elk and exclude from consideration areas where elk-human conflicts were more likely. Habitats in the state were categorized as 66% unsuitable, 16.7% low, 17% medium, and <1% high suitability for elk. The coastal plain and Piedmont contained the most suitable habitat, but prospective reintroduction sites were largely excluded from consideration due to extensive agricultural activities and pervasiveness of secondary roads. We ranked 31 areas (≥ 500 km2) based on their suitability for reintroduction. The central region of the state contained the top five ranked areas. The Blue Ridge Mountains, where the extant population of elk occurs, was ranked 21st. Our work provides a benchmark for decision makers to evaluate potential consequences and trade-offs associated with the selection of prospective elk reintroduction sites.

    1992-01-01

    Surplus cereal production in the EEC and decreasing product prices, mainly for cereals, has prompted considerable interest for new earnings in arable farming. The objective was to examine whether suggested new crops (fibre, oil, medicinal and alternative grains crops) could be considered as real alternatives. Whether a specific crop can compete economically with cereals and whether there is a market demand for the crop is analyzed. The described possibilities will result in ca. 50,000 hectares of new crops. It is expected that they would not immediately provide increased earnings, but in the long run expected price developments are more positive than for cereals. The area for new crops will not solve the current surplus cereal problem as the area used for new crops is only 3% of that used for cereals. Preconditions for many new crops is further research activities and development work as well as the establishment of processing units and organizational initiatives. Presumably, it is stated, there will then be a basis for a profitable production of new crops for some farmers. (AB) (47 refs.)

    Resource-management techniques must be applied to assess the risks, benefits, priorities, and potentials of the different energy options as prospective slowdowns in the flow of crude oil threaten recurring energy crises. The 23 contributors to this book use various managerial approaches in the formulation of energy policies. There is little agreement among the remedies put forth as to which policies will best achieve a balanced energy system. While some experts argue that Canadian energy policy should emphasize intensive development of coal, others claim that it ought to strive for greater reliance on electricity, and still others contend that the transition to soft energy paths is a preferable policy approach. The essays offer a broad range of policy responses, examining not only technical and economic possibilities, but political and institutional alternatives as well. 147 references, 18 figures, 30 tables.

  4. Bell's inequality without alternative settings

    2003-01-01

    A suitable generalized measurement described by a 4-element positive operator-valued measure (POVM) on each particle of a two-qubit system in the singlet state is, from the point of view of Einstein, Podolsky, and Rosen's (EPR's) criterion of elements of reality, equivalent to a random selection between two alternative projective measurements. It is shown that an EPR-experiment with a fixed POVM on each particle provides a violation of Bell's inequality without requiring local observers to choose between the alternatives. This approach could be useful for designing a loophole-free test of Bell's inequality

    Full Text Available The investigation of aviation alternative fuels has increased significantly in recent years in an effort to reduce the environment and climate impact by aviation industry. Special requirements have to be met for qualifying as a suitable aviation fuel. The fuel has to be high in energy content per unit of mass and volume, thermally stable and avoiding freezing at low temperatures. There are also many other special requirements on viscosity, ignition properties and compatibility with the typical aviation materials. There are quite a few contending alternative fuels which can be derived from coal, natural gas and biomass.[...

    2007-04-01

    Full Text Available Abstract Consumption of trans fats is associated with an increase of cardiovascular disease (CVD risk. To comply with regulatory policies and public health authorities recommendations, trans fats should be replaced in food products. The study by Sundram et al. (Nutrition & Metabolism 2007, 4:3 reporting the effect on CVD risk factors of interesterified fat (IE and partially hydrogenated soybean oil (PHSO compared to palm olein (POL has been critically analyzed. The study design and in particular the composition of the tested fats was not suitable to properly answer the question raised regarding the effect of alternative ingredients to trans fats on plasma lipids. The observed effects are divergent with predicted data derived from the literature model consolidated using the individual results of 60 randomized clinical trials. The results of the study published by Sundram and co-workers have to be considered with awareness.

  7. Cost-effective design of economic instruments in nutrition policy

    Full Text Available Abstract This paper addresses the potential for using economic regulation, e.g. taxes or subsidies, as instruments to combat the increasing problems of inappropriate diets, leading to health problems such as obesity, diabetes 2, cardiovascular diseases etc. in most countries. Such policy measures may be considered as alternatives or supplements to other regulation instruments, including information campaigns, bans or enhancement of technological solutions to the problems of obesity or related diseases. 7 different food tax and subsidy instruments or combinations of instruments are analysed quantitatively. The analyses demonstrate that the average cost-effectiveness with regard to changing the intake of selected nutritional variables can be improved by 10–30 per cent if taxes/subsidies are targeted against these nutrients, compared with targeting selected food categories. Finally, the paper raises a range of issues, which need to be investigated further, before firm conclusions about the suitability of economic instruments in nutrition policy can be drawn.

  8. Preliminary geological suitability assessment for LILW disposal

    International Nuclear Information System (INIS)

    Tomse, P.; Mele, I.

    2001-01-01

    Due to the growing need for a final disposal of LILW, the final solution for the short-lived LILW is the key issue of radioactive waste management in Slovenia at the moment. ARAO - the Slovenian Agency for Radwaste Management - is intensely involved in the re-initiated site selection process for a LILW repository. In this new process we are trying to combine as best as possible the technical, geologically-led and the advocacy-site selection processes. By a combination of technical and volunteer approach to the site selection we wish to guarantee high public involvement and sufficient flexibility of the process to adapt to specific conditions or new circumstances while the project is ongoing. In the technical phase, our tendency is to retain a larger number of potential areas/sites. We also keep open the possibility of choosing the type of repository. The decision between the surface and underground option will be made only once the site has been defined. In accordance with the IAEA recommendations the site selection process is divided into four stages: the conceptual and planning stage, area survey stage, site characterisation stage and site confirmation stage. Last year the area survey stage was started. In the preliminary geological suitability assessment the required natural predisposition of Slovene territory was assessed in order to locate geologically suitable formations. The assessment of natural conditions of the system was based on consideration of the main geological, hydro-geological and seismotectonic conditions. It was performed with ARC/INFO technology. The results are compiled in a map, showing potential areas for underground and surface disposal of LILW in Slovenia. It has been established that there is a potential suitability for both surface and underground disposal on about 10 000 km 2 of the Slovenian territory, which represents almost half of the entire Slovenian territory. These preliminary results are now being carefully re-examined. As an

    English. A special committe of the Canadian House of Commons was established on 23 May 1980 to investigate the use of alternative energy sources such as 'gasohol', liquified coal, solar energy, methanol, wind and tidal power, biomass, and propane. In its final report, the committee envisions an energy system for Canada based on hydrogen and electricity, using solar and geothermal energy for low-grade heat. The committe was not able to say which method of generating electricty would dominate in the next century, although it recommends that fossil fuels should not be used. The fission process is not specifically discussed, but the outlook for fusion was investigated, and continued governmental support of fusion research is recommended. The report proposes some improvements in governmental energy organizations and programs

    A new approach for constructing a projective-synchronized chaotic slave system is proposed in this paper. This method is based on suitable separation by decomposing the system as the linear part and the nonlinear one. From matrix measure theory, some simple but efficient criteria are derived for projective synchronization of chaotic system. Numerical simulations for the Lorenz system show that this control method works very well

    Pleasance, L.D.

    1979-11-01

    One objective of research on inertial confinement fusion is the development of a power generating system based on this concept. Realization of this goal will depend on the availability of a suitable laser or other system to drive the power plant. The primary laser systems used for laser fusion research, Nd 3+ : Glass and CO 2 , have characteristics which may preclude their use for this application. Glass lasers are presently perceived to be incapable of sufficiently high average power operation and the CO 2 laser may be limited by and issues associated with target coupling. These general perceptions have encouraged a search for alternatives to the present systems. The search for new lasers has been directed generally towards shorter wavelengths; most of the new lasers discovered in the past few years have been in the visible and ultraviolet region of the spectrum. Virtually all of them have been advocated as the most promising candidate for a fusion driver at one time or another

  12. Alternative energy review

    International Nuclear Information System (INIS)

    1991-09-01

    A review is presented of electricity generation technologies which are considered to be alternatives to more conventional technologies. The review is limited to those technologies which have application in Ontario, and provides descriptions, technical and economic assessments, environmental information, and forecasts of potential use of solar energy, wind energy, fuel cells, biomass energy, peat, and municipal solid wastes. Of these technologies, only municipal solid waste combustion is economically viable under current conditions, but government policies prohibit the implementation of new facilities. Certain photovoltaic and wind energy technologies are being found viable for remote sites unconnected to the power grid. Wood waste combustion is viable in the forest products industry. The total potential contribution of these six alternative technologies to Ontario's energy production is forecast at under 190 MW to a range of 685-1,465 MW by the year 2005, according to three different scenarios. The technologies showing the greatest future promise are fuel cells, photovoltaics, and biomass. Except for municipal waste combustion, cost continues to be a significant barrier to utility-scale application of alternative generation technologies in Ontario. However, private individuals and corporations (non-utility generators) may adopt some of these technologies in the absence of access to the power grid, in cogeneration applications, or for demonstration purposes. 120 refs., 79 figs., 93 tabs

    Bretteville, Camilla; Soefting, Guri Bang

    2000-09-01

    Taxation as an instrument for environmental policy (green taxes) has been a topic of heated debate in Norway for almost 30 years. The subject of environmental taxes has time after time inflamed both policy makers and scholars alike. The suitability of green taxes as a policy instrument was first discussed in the 1970s. The 1980s introduced the idea that income from green taxes would make reductions in other taxes possible: a green tax reform. In the 1990s, the tax discussion boiled down to whether or not all polluters should face the same carbon tax. Lately, however, the discussion around the Kyoto Protocol has led to increased interest around the alternative of introducing a system of tradable emission quotas. Environmental taxation might thus be a declining policy instrument in Norway. This is contrary to recent developments in several other European countries such as the United Kingdom, Germany, and the Netherlands. This paper explores why the idea of a green tax reform never got off the ground in Norway by providing an overview of Norwegian environmental policy in the period from 1972 to early 2000. (author)

    2016-04-01

    Full Text Available Overhead systems are the dominant irrigation technology in many parts of the world, but they are not widely used in California even though they have higher water application efficiency than furrow irrigation systems and lower labor requirements than drip systems. With water and labor perennial concerns in California, the suitability of overhead systems merits consideration. From 2008 through 2013, in studies near Five Points, California, we evaluated overhead irrigation for wheat, corn, cotton, tomato, onion and broccoli as an alternative to furrow and drip irrigation. With the exception of tomato, equal or increased yields were achieved with overhead irrigation. Many variables are involved in the choice of an irrigation system, but our results suggest that, with more research to support best management practices, overhead irrigation may be useful to a wider set of California farmers than currently use it.

  18. Choosing a suitable sample size in descriptive sampling

    International Nuclear Information System (INIS)

    Lee, Yong Kyun; Choi, Dong Hoon; Cha, Kyung Joon

    2010-01-01

    Descriptive sampling (DS) is an alternative to crude Monte Carlo sampling (CMCS) in finding solutions to structural reliability problems. It is known to be an effective sampling method in approximating the distribution of a random variable because it uses the deterministic selection of sample values and their random permutation,. However, because this method is difficult to apply to complex simulations, the sample size is occasionally determined without thorough consideration. Input sample variability may cause the sample size to change between runs, leading to poor simulation results. This paper proposes a numerical method for choosing a suitable sample size for use in DS. Using this method, one can estimate a more accurate probability of failure in a reliability problem while running a minimal number of simulations. The method is then applied to several examples and compared with CMCS and conventional DS to validate its usefulness and efficiency

  19. Niche suitability affects development: skull asymmetry increases in less suitable areas.

    Directory of Open Access Journals (Sweden)

    Renan Maestri

    Full Text Available For conservation purposes, it is important to take into account the suitability of a species to particular habitats; this information may predict the long-term survival of a species. In this sense, morphological measures of developmental stress, such as fluctuating asymmetry, can be proxies for an individual's performance in different regions. In this study, we conducted tests to determine whether areas with different levels of suitability for a species (generated by ecological niche models were congruent with morphological markers that reflect environmental stress and morphological variance. We generated a Maxent niche model and compared the suitability assessments of several areas with the skull morphology data (fluctuating asymmetry and morphological disparity of populations of the Atlantic forest endemic to Brazil rodent Akodon cursor. Our analyses showed a significant negative relationship between suitability levels and fluctuating asymmetry levels, which indicates that in less suitable areas, the individuals experience numerous disturbances during skull ontogeny. We have not found an association between morphological variance and environmental suitability. As expected, these results suggest that in environments with a lower suitability, developmental stress is increased. Such information is helpful in the understanding of the species evolution and in the selection of priority areas for the conservation of species.

  20. Agroforestry suitability analysis based upon nutrient availability mapping: a GIS based suitability mapping

    Directory of Open Access Journals (Sweden)

    2017-05-01

    Full Text Available Agroforestry has drawn the attention of researchers due to its capacity to reduce the poverty and land degradation, improve food security and mitigate the climate change. However, the progress in promoting agroforestry is held back due to the lack of reliable data sets and appropriate tools to accurately map and to have an adequate decision making system for agroforestry modules. Agroforestry suitability being one special form of land suitability is very pertinent to study in the current times when there is tremendous pressure on the land as it is a limited commodity. The study aims for applying the geo-spatial tools towards visualizing various soil and environmental data to reveal the trends and interrelationships and to achieve a nutrient availability and agroforestry suitability map. Using weight matrix and ranks, individual maps were developed in ArcGIS 10.1 platform to generate nutrient availability map, which was later used to develop agroforestry suitability map. Watersheds were delineated using DEM in some part of the study area and were evaluated for prioritizing it and agroforestry suitability of the watersheds were also done as per the schematic flowchart. Agroforestry suitability regions were delineated based upon the weight and ranks by integrated mapping. The total open area was identified 42.4% out of which 21.6% area was found to have high suitability towards agroforestry. Within the watersheds, 22 village points were generated for creating buffers, which were further evaluated showing its proximity to high suitable agroforestry sites thus generating tremendous opportunity to the villagers to carry out agroforestry projects locally. This research shows the capability of remote sensing in studying agroforestry practices and in estimating the prominent factors for its optimal productivity. The ongoing agroforestry projects can be potentially diverted in the areas of high suitability as an extension. The use of ancillary data in GIS

  3. Environmental siting suitability analysis for commercial scale ocean renewable energy: A southeast Florida case study

    Science.gov (United States)

    Mulcan, Amanda

    This thesis aims to facilitate the siting and implementation of Florida Atlantic University Southeast National Marine Renewable Energy Center (FAU SNMREC) ocean current energy (OCE) projects offshore southeastern Florida through the analysis of benthic anchoring conditions. Specifically, a suitability analysis considering all presently available biologic and geologic datasets within the legal framework of OCE policy and regulation was done. OCE related literature sources were consulted to assign suitability levels to each dataset, ArcGIS interpolations generated seafloor substrate maps, and existing submarine cable pathways were considered for OCE power cables. The finalized suitability map highlights the eastern study area as most suitable for OCE siting due to its abundance of sand/sediment substrate, existing underwater cable route access, and minimal biologic presence. Higher resolution datasets are necessary to locate specific OCE development locales, better understand their benthic conditions, and minimize potentially negative OCE environmental impacts.

    2012-09-01

    The next generation reactors in the U.S. are an opportunity for vendors to build new reactor technology with advanced Instrumentation and Control Systems (control rooms, DCS, etc.). The advances made in the development of many current generation operating reactors in other parts of the world are being used in the design and construction of new plants. These new plants are expected to have fully integrated digital control rooms, computerized procedures, integrated surveillance testing with on-line monitoring and a major effort toward improving the O&M and fault survivability of the overall systems. In addition the designs are also incorporating major improvements in the man-machine interface based on lessons learned in nuclear and other industries. The above relates primarily to the scope of supply in instrumentation and control systems addressed by Chapter 7 of the Standard Review Plan (SRP) NUREG-0800 (Reference 9.5), and the associated Balance of Plant (BOP) I&C systems. This does not relate directly to the actuator and motor, breaker, initiation circuitry, valve position, etc. which is the subject of this report and normally outside of the traditional Distributed Control System (DCS), for both safety and non-safety systems. The recommendations presented in this report will be used as input to I&C research programming for the implementation of lessons learned during the early phases of new build both for large light water reactors (LWR) and also small modular reactors (SMR). This report is intended to support current research plans and provide user (vendor, owner-operator) input to the optimization of these research plans.

    The results obtained in different international intercomparisons on passive radon monitors have been analysed with the aim of identifying a suitable radon monitoring device for workplaces. From this analysis, the passive radon device, first developed for personal dosimetry in mines by the National Radiation Protection Board, UK (NRPB), has shown the most suitable set of characteristics. This radon monitor consists of a diffusion chamber, made of conductive plastic with less than 2 cm height, containing a CR-39 film (Columbia Resin 1939), as track detector. Radon detectors in workplaces may be exposed only during the working hours, thus requiring the storage of the detectors in low-radon zones when not exposed. This paper describes how this problem can be solved. Since track detectors are also efficient neutron dosemeters, care should be taken when radon monitors are used in workplaces, where they may be exposed to neutrons, such as on high altitude mountains, in the surroundings of high energy X ray facilities (where neutrons are produced by (gamma, n) reactions) or around high energy particle accelerators. To this end, the response of these passive radon monitors to high energy neutron fields has been investigated. (author)

    Advancement of U.S. scientific, security, and economic interests requires high performance propulsion systems to support missions beyond low Earth orbit. A robust space exploration program will include robotic outer planet and crewed missions to a variety of destinations including the moon, near Earth objects, and eventually Mars. Past studies, in particular those in support of both the Strategic Defense Initiative (SDI) and the Space Exploration Initiative (SEI), have shown nuclear thermal propulsion systems provide superior performance for high mass high propulsive delta-V missions. In NASA's recent Mars Design Reference Architecture (DRA) 5.0 study, nuclear thermal propulsion (NTP) was again selected over chemical propulsion as the preferred in-space transportation system option for the human exploration of Mars because of its high thrust and high specific impulse (∼900 s) capability, increased tolerance to payload mass growth and architecture changes, and lower total initial mass in low Earth orbit. The recently announced national space policy2 supports the development and use of space nuclear power systems where such systems safely enable or significantly enhance space exploration or operational capabilities. An extensive nuclear thermal rocket technology development effort was conducted under the Rover/NERVA, GE-710 and ANL nuclear rocket programs (1955-1973). Both graphite and refractory metal alloy fuel types were pursued. The primary and significantly larger Rover/NERVA program focused on graphite type fuels. Research, development, and testing of high temperature graphite fuels was conducted. Reactors and engines employing these fuels were designed, built, and ground tested. The GE-710 and ANL programs focused on an alternative ceramic-metallic 'cermet' fuel type consisting of UO2 (or UN) fuel embedded in a refractory metal matrix such as tungsten. The General Electric program examined closed loop concepts for space or terrestrial applications as well as

    The conditioning of radioactive waste from nuclear power plants and in some countries even of weapons plutonium is an important issue for science and society. Therefore the research on appropriate matrices for the immobilization of fission products and actinides is of great interest. Beyond the widely used borosilicate glasses, ceramics are promising materials for the conditioning of actinides like U, Np, Pu, Am, and Cm. Monazite-type ceramics with general composition LnPO{sub 4} (Ln = La to Gd) and solid solutions of monazite with cheralite or huttonite represent important materials in this field. Monazite appears to be a promising candidate material, especially because of its outstanding properties regarding radiation resistance and chemical durability. This article summarizes the most recent results concerning the characterization of monazite and respective solid solutions and the study of their chemical, thermal, physical and structural properties. The aim is to demonstrate the suitability of monazite as a secure and reliable waste form for actinides. (orig.)

Previous research has begun to explore the suitability of internal versus external successor in family firms with regard to relevant knowledge types. This paper builds on the contingency model...... of family business succession in order to understand when family successors are preferred because of their family-specific experiential knowledge. A case study analysis from the German-Danish border region explores how a family firm has used internal successors for the last 12 successions.

    Previous work had identified glass compositions that were suitable for vitrifying current and future high level wastes from the Prototype Fast Reactor (PFR) fuel reprocessing plant. Further work on these glasses has shown that: a) Foaming and crystallisation can occur under certain conditions, both probably associated with the presence of iron in the waste. Either of these could lead to greater difficulties in processing. b) Inconel 690, the preferred JCM (Joule-heated Ceramic Melter) electrode material has an acceptable corrosion rate at 1200 0 C: ca 0.6mm.y -1 . c) The leach rates are unaffected by radiation damage. The density of the glass decreases slightly with α-dose, with a dependency that extrapolates, at infinite time, to an 0.13% linear expansion. d) The concentrations of the radiologically important elements Tc, Np, Pu and Am, observed in a 'repository simulation' leach test, were satisfactorily low.

  19. Alternatives to nuclear energy

    International Nuclear Information System (INIS)

    Terrado, E.N.

    1981-01-01

    This article discusses several possibilities as alternatives to nuclear energy and their relevance to the Philippine case. The major present and future fuel alternatives to petroleum and nuclear energy are coal, geothermal heat, solar energy and hydrogen, the first two of which are being used. Different conversion technologies are also discussed for large scale electricity production namely solar thermal electric conversion (STC), photovoltaic electric power system (PEPS) and ocean thermal energy conversion (OTEC). Major environmental considerations affect the choice of energy sources and technologies. We have the problem of long term accumulation of radioactive waste in the case of nuclear energy; in geothermal and fossil-fuels carbon dioxide uranium and accumulation may cause disastrous consequences. With regard to Philippine option, the greatest considerations in selecting alternative energy options would be resources availability - both energy and financial and technology status. For the country's energy plan, coal and geothermal energy are expected to play a significant role. The country's coal resources are 1.4 billion metric tons. For geothermal energy, 25 volcanic centers were identified and has a potential equivalent to 2.5 x 10 6 million barrels of oil. Solar energy if harnessed, being in the sunbelt, averaging some 2000 hours a year could be an energy source. The present dilemma of the policy maker is whether national resources are better spent on large scale urban-based energy projects or whether those should be focused on small scale, rural oriented installations which produced benefits to the more numerous and poorer members of the population.

  1. Evaluating sub-national building-energy efficiency policy options under uncertainty: Efficient sensitivity testing of alternative climate, technological, and socioeconomic futures in a regional integrated-assessment model

    Improving the energy efficiency of building stock, commercial equipment, and household appliances can have a major positive impact on energy use, carbon emissions, and building services. Sub-national regions such as the U.S. states wish to increase energy efficiency, reduce carbon emissions, or adapt to climate change. Evaluating sub-national policies to reduce energy use and emissions is difficult because of the large uncertainties in socioeconomic factors, technology performance and cost, and energy and climate policies. Climate change itself may undercut such policies. However, assessing all of the uncertainties of large-scale energy and climate models by performing thousands of model runs can be a significant modeling effort with its accompanying computational burden. By applying fractional–factorial methods to the GCAM-USA 50-state integrated-assessment model in the context of a particular policy question, this paper demonstrates how a decision-focused sensitivity analysis strategy can greatly reduce computational burden in the presence of uncertainty and reveal the important drivers for decisions and more detailed uncertainty analysis. - Highlights: • We evaluate building energy codes and standards for climate mitigation. • We use an integrated assessment model and fractional factorial methods. • Decision criteria are energy use, CO2 emitted, and building service cost. • We demonstrate sensitivity analysis for three states. • We identify key variables to propagate with Monte Carlo or surrogate models

  2. Mapping suitability of rice production systems for mitigation: Strategic approach for prioritizing improved irrigation management across scales

    2016-04-01

    After the successful conclusion of the COP21 in Paris, many developing countries are now embracing the task of reducing emissions with much vigor than previously. In many countries of South and South-East Asia, the agriculture sector constitutes a vast share of the national GHG budget which can mainly be attributed to methane emissions from flooded rice production. Thus, rice growing countries are now looking for tangible and easily accessible information as to how to reduce emissions from rice production in an efficient manner. Given present and future food demand, mitigation options will have to comply with aim of increasing productivity. At the same time, limited financial resources demand for strategic planning of potential mitigation projects based on cost-benefit ratios. At this point, the most promising approach for mitigating methane emissions from rice is an irrigation technique called Alternate Wetting and Drying (AWD). AWD was initially developed for saving water and subsequently, represents an adaptation strategy in its own right by coping with less rainfall. Moreover, AWD also reduces methane emissions in a range from 30-70%. However, AWD is not universally suitable. It is attractive to farmers who have to pump water and may save fuel under AWD, but renders limited incentives in situations where there is no real pressing water scarcity. Thus, planning for AWD adoption at larger scale, e.g. for country-wide programs, should be based on a systematic prioritization of target environments. This presentation encompasses a new methodology for mapping suitability of water-saving in rice production - as a means for planning adaptation and mitigation programs - alongside with preliminary results. The latter comprises three new GIS maps on climate-driven suitability of AWD in major rice growing countries (Philippines, Vietnam, Bangladesh). These maps have been derived from high-resolution data of the areal and temporal extent of rice production that are now

    1995-09-01

    The focus of this news brief is on the Community-based Sustainable Family Planning/Maternal and Child Health (FP/MCH) Project promoted in Bangladesh, Laos, Nepal, and the Philippines. The project emphasizes women's involvement as policy makers and evaluators. The aim is to involve women at all project levels as part of an effort to correct gender imbalances. Programs are being directed toward sustainability. Women are placed in positions at each level of the tiered system of steering committees, which range from local village committees to central committees. Men may still retain the top positions, but women are given decision making power at the highest levels of policy and program development and implementation. The Asia region is challenged by quality of care issues related to reproductive health services. Program expansion is proceeding into rural areas with outreach services and fee charging. Projects are community-based, which means mobilization of community people. The community approach is suitable to an Asian culture that does not adhere to strict rules of privacy. Women's groups are eager to discuss sensitive issues such as contraception and to offer personal experiences and solutions to problems. Mass meetings and individual counseling sessions are available. IEC materials are available to the Asian FP/MCH program from JOICFP. Some of these materials promote the concept of the Asian community spirit as a building block of development. The Asian approach is an alternative to Western models and may be valid for other regions.

    Heavy metals are a hazard to marine fauna and human health. In this study we assess stable isotopes and metal content in Prionace glauca and Isurus oxyrinchus and analyse these results within and among other species and across regions and geographical areas. Also, we evaluate their suitability, together with Raja clavata and Galeorhinus galeus, as Mid-Atlantic bioindicators. Prionace glauca and I. oxyrinchus shared the same trophic level in a pelagic food web and did not present significant differences between genders or metals, except for As. Arsenic and Hg accumulated while Cd and Pb were not detected. One I. oxyrinchus presented Hg values above regulatory limits. A high Hg exposure was associated with I. oxyrinchus since its maximum weekly intake was exceeded. Elasmobranchs can be used as metal sentinels, each presenting different key features which defines a good marine bioindicator, allowing long-term monitoring at different temporal and spatial scales. - Highlights: • We analysed P. glauca and I. oxyrinchus muscle from Mid-Atlantic. • We determined stable isotopes, trophic ecology and heavy metal content. • Results reflect bioaccumulation for As and Hg. • Oxyrinchus already presented Hg values above regulatory limits. • Mid-Atlantic elasmobranchs appear to be effective metal bioindicators.

    It cannot be assumed that storage enclosures considered safe for traditionally printed images and documents are suitable for modern, digitally printed materials. In this project, a large variety of digital print types were tested using a modified version of the ISO 18916 Imaging materials-Processed imaging materials-Photographic activity test for enclosure materials standard to assess the risk to digital prints by paper enclosures known to be inert or reactive with traditional photographic prints. The types of enclosures tested included buffered and non-buffered cotton papers, and groundwood paper. In addition, qualitative filter paper that had been wetted and dried with either an acidic or basic solution was also tested to determine the effects of enclosure pH on digitally printed materials. It was determined that, in general, digital prints tended to be less reactive with various enclosure types than traditional prints. Digital prints were most sensitive to paper that contained groundwood. The enclosure reactivity test results were then integrated with previous published work on the tendencies of various enclosure types to abrade, ferrotype, or block to digital prints in order to create a comprehensive set of recommendations for digital print storage enclosures.

  10. Perspective in site-suitability modelling

    International Nuclear Information System (INIS)

    Chartier, M.

    1989-01-01

    The Steering Committee for Nuclear Energy of the OECD-Nuclear Energy Agency decided in April 1981 to set up a Co-ordinated Research and Environmental Surveillance Programme relevant to sea disposal of radioactive waste (CRESP) with the objective of reinforcing the scientific basis of future assessments of the continued suitability of the North-East Atlantic site to be made under the NEA Multilateral Consultation and Surveillance Mechanism. A major component of the initial CRESP plan was the development of a site-specific model to predict radionuclide transfer rates and patterns in the marine environment. A new general approach to the design of such a site-specific model is discussed.Although this approach originates partly from methodologies presented in GESAMP partly from an approach put forward within the NEA Seabed Working Group/Geochemical and Physical Oceanography Task Group and partly from methods previously agreed by the CRESP Modelling Task Group, the modelling philosophy developed in the text expressed the personal viewpoint of the author. This text aims to state the present methods of modelling the marine transfer of radionuclides and to anticipate modelling strategies which may be adopted in the future (in France for example), but it does not necessarily meet present NEA viewpoints and the philosophy of other CRESP participating countries

    Translocations are important tools in the field of conservation. Despite increased use over the last few decades, the appropriateness of translocations for amphibians and reptiles has been debated widely over the past 20 years. To provide a comprehensive evaluation of the suitability of amphibians and reptiles for translocation, we reviewed the results of amphibian and reptile translocation projects published between 1991 and 2006. The success rate of amphibian and reptile translocations reported over this period was twice that reported in an earlier review in 1991. Success and failure rates were independent of the taxonomic class (Amphibia or Reptilia) released. Reptile translocations driven by human-wildlife conflict mitigation had a higher failure rate than those motivated by conservation, and more recent projects of reptile translocations had unknown outcomes. The outcomes of amphibian translocations were significantly related to the number of animals released, with projects releasing over 1000 individuals being most successful. The most common reported causes of translocation failure were homing and migration of introduced individuals out of release sites and poor habitat. The increased success of amphibian and reptile translocations reviewed in this study compared with the 1991 review is encouraging for future conservation projects. Nevertheless, more preparation, monitoring, reporting of results, and experimental testing of techniques and reintroduction questions need to occur to improve translocations of amphibians and reptiles as a whole.

    Ewen Speed and Russell Mannion correctly identify several contours of the challenges for health policy in what it is useful to think of as a post-democratic era. I argue that the problem for public health is not populism per se, but rather the distinctive populism of the right coupled with the failure of the left to develop compelling counternarratives. Further, defences of 'science' must be tempered by recognition of the unavoidably political dimensions of the (mis)use of scientific findings in public policy. © 2017 The Author(s); Published by Kerman University of Medical Sciences.

    2015-07-01

    Full Text Available Densified Biomass Solid Fuel (DBSF is a typical solid form of biomass, using agricultural and forestry residues as raw materials. DBSF utilization is considered to be an alternative to fossil energy, like coal in China, associated with a reduction of environmental pollution. China has abundant biomass resources and is suitable to develop DBSF. Until now, a number of policies aimed at fostering DBSF industry have been proliferated by policy makers in China. However, considering the seasonality and instability of biomass resources, these inefficiencies could trigger future scarcities of biomass feedstocks, baffling the resilience of biomass supply chains. Therefore, this review paper focuses on DBSF policies and strategies in China, based on the supply chain framework. We analyzed the current developing situation of DBSF industry in China and developed a framework for policy instruments based on the supply chain steps, which can be used to identify and assess the deficiencies of current DBSF industry policies, and we proposed some suggestions. These findings may inform policy development and identify synergies at different steps in the supply chain to enhance the development of DBSF industry.

    NHS policy encourages general practices to introduce alternatives to the face-to-face consultation, such as telephone, email, e-consultation systems, or internet video. Most have been slow to adopt these, citing concerns about workload. This project builds on previous research by focusing on the experiences of patients and practitioners who have used one or more of these alternatives. To understand how, under what conditions, for which patients, and in what ways, alternatives to face-to-face consultations present benefits and challenges to patients and practitioners in general practice. Focused ethnographic case studies took place in eight UK general practices between June 2015 and March 2016. Non-participant observation, informal conversations with staff, and semi-structured interviews with staff and patients were conducted. Practice documents and protocols were reviewed. Data were analysed through charting and the 'one sheet of paper' mind-map method to identify the line of argument in each thematic report. Case study practices had different rationales for offering alternatives to the face-to-face consultation. Beliefs varied about which patients and health issues were suitable. Co-workers were often unaware of each other's practice; for example, practice policies for use of e-consultations systems with patients were not known about or followed. Patients reported benefits including convenience and access. Staff and some patients regarded the face-to-face consultation as the ideal. Experience of implementing alternatives to the face-to-face consultation suggests that changes in patient access and staff workload may be both modest and gradual. Practices planning to implement them should consider carefully their reasons for doing so and involve the whole practice team. © British Journal of General Practice 2018.

Ainda que se considere os recuos, obstáculos e entraves que caracterizam as mudanças de paradigmas em políticas públicas educacionais, é de se ressaltar que, nos últimos anos, tem-se construído, em várias cidades do país, novas formas de fazer política pública em educação. Tais experiências refletem projetos que trazem consigo a concepção de democratização das relações entre Estado e sociedade, e podem representar novas esperanças de solução para velhos problemas.This paper examines the possibility of constructing alternative public education policies, not only theoretical proposals, but also educational policies that have been constructed in opposition to the Brazilian tradition of vertical relations between the state and civil society. Even taking into account the difficulties that characterise paradigm shift in education policies, it can be seen that new approaches to such policies have been constructed in a number of brazilian cities in recent years. These experiences reflect forms of government that involve the concept of democratisation of the relations between state and society, which may represent new hope for solving old problems.

    1989-04-01

    The Director General of the IAEA stressed the need for energy policies and other measures which would help to slow and eventually halt the present build-up of carbon dioxide, methane and other so-called greenhouse gases, which are held to cause global warming. He urged that nuclear power and various other sources of energy, none of which contribute to global warming, should not be seen as alternatives, but should all be used to counteract the greenhouse effect. He pointed out that the commercially used renewable energies, apart from hydropower, currently represent only 0.3% of the world's energy consumption and, by contrast, the 5% of the world's energy consumption coming from nuclear power is not insignificant. Dr. Blix noted that opposition for nuclear power stems from fear of accidents and concern about the nuclear wastes. But no generation of electricity, whether by coal, hydro, gas or nuclear power, is without some risk. He emphasized that safety can never be a static concept, and that many new measures are being taken by governments and by the IAEA to further strengthen the safety of nuclear power

The purpose of the report is: (1) to provide background information on alternative transportation fuels and replacement fuels compared with gasoline and diesel fuel, and (2) to furnish preliminary estimates of alternative transportation fuels and alternative fueled vehicles as required by the Energy Policy Act of 1992 (EPACT), Title V, Section 503, ``Replacement Fuel Demand Estimates and Supply Information.`` Specifically, Section 503 requires the EIA to report annually on: (1) the number and type of alternative fueled vehicles in existence the previous year and expected to be in use the following year, (2) the geographic distribution of these vehicles, (3) the amounts and types of replacement fuels consumed, and (4) the greenhouse gas emissions likely to result from replacement fuel use. Alternative fueled vehicles are defined in this report as motorized vehicles licensed for on-road use, which may consume alternative transportation fuels. (Alternative fueled vehicles may use either an alternative transportation fuel or a replacement fuel.) The intended audience for the first section of this report includes the Secretary of Energy, the Congress, Federal and State agencies, the automobile manufacturing industry, the transportation fuel manufacturing and distribution industries, and the general public. The second section is designed primarily for persons desiring a more technical explanation of and background for the issues surrounding alternative transportation fuels.

    This study evaluated the technical suitability of Yucca Mountain, Nevada, as a potential site for a mined geologic repository for the permanent disposal of radioactive waste. The evaluation was conducted primarily to determine early in the site characterization program if there are any features or conditions at the site that indicate it is unsuitable for repository development. A secondary purpose was to determine the status of knowledge in the major technical areas that affect the suitability of the site. This early site suitability evaluation (ESSE) was conducted by a team of technical personnel at the request of the Associate Director of the US Department of Energy (DOE) Office of Geologic Disposal, a unit within the DOE's Office of Civilian Radioactive Waste Management. The Yucca Mountain site has been the subject of such evaluations for over a decade. In 1983, the site was evaluated as part of a screening process to identify potentially acceptable sites. The site was evaluated in greater detail and found suitable for site characterization as part of the Environmental Assessment (EA) (DOE, 1986) required by the Nuclear Waste Policy Act of 1982 (NWPA). Additional site data were compiled during the preparation of the Site Characterization Plan (SCP) (DOE, 1988a). This early site suitability evaluation has considered information that was used in preparing both-documents, along with recent information obtained since the EA and SCP were published. This body of information is referred to in this report as ''current information'' or ''available evidence.''

    The New Brunswick Market Design Committee will address environmental concerns within the context of the new energy policy and market rules for the newly restructured electric power industry. The new rules that come with power restructuring will in some ways facilitate environmental protection but they can also complicate it. With open access markets, it will be possible to coordinate evolving energy frameworks with current environmental objectives. Restructuring provides an opportunity to create incentives and guidelines to operate in an environmentally sustainable manner, as suggested in the New Brunswick Energy Policy, White Paper which outlines green pricing, the development of a provincial Climate Change Action Plan, and promotion of alternative energy. The Market Design Committee examined the environmental concerns listed within the White Paper that pertain to the generation and transmission of electricity. These include the integration of energy and environmental policy. Other issues addressed in this report were trans-boundary and global air emissions, the development of a provincial climate change action plan, and a federal-provincial climate change framework agreement. New Brunswick will encourage the development of pilot studies that demonstrate the benefits of renewable and alternative technologies and that help promote the market to manufacture, sell and maintain renewable and alternative technologies in small-scale on-site power generation. This report also discussed the 4 key air pollutants for which specific treatment has been defined, including sulphur dioxide, nitrogen oxides, mercury and carbon dioxide. Recommendations for reducing these emissions include the use of renewable energy sources, the use of lower carbon fuels, increased efficiency of power transmission/generation/distribution systems, reducing power demand by the industrial sector, and promoting energy efficient building codes. 34 refs., 1 tab

    Patient blood management is introduced as a new concept that involves the combined use of transfusion alternatives. In elective adult total hip- or knee-replacement surgery patients, the authors conducted a large randomized study on the integrated use of erythropoietin, cell saver, and/or postoperative drain reinfusion devices (DRAIN) to evaluate allogeneic erythrocyte use, while applying a restrictive transfusion threshold. Patients with a preoperative hemoglobin level greater than 13 g/dl were ineligible for erythropoietin and evaluated for the effect of autologous blood reinfusion. Patients were randomized between autologous reinfusion by cell saver or DRAIN or no blood salvage device. Primary outcomes were mean intra- and postoperative erythrocyte use and proportion of transfused patients (transfusion rate). Secondary outcome was cost-effectiveness. In 1,759 evaluated total hip- and knee-replacement surgery patients, the mean erythrocyte use was 0.19 (SD, 0.9) erythrocyte units/patient in the autologous group (n = 1,061) and 0.22 (0.9) erythrocyte units/patient in the control group (n = 698) (P = 0.64). The transfusion rate was 7.7% in the autologous group compared with 8.3% in the control group (P = 0.19). No difference in erythrocyte use was found between cell saver and DRAIN groups. Costs were increased by €298 per patient (95% CI, 76 to 520). In patients with preoperative hemoglobin levels greater than 13 g/dl, autologous intra- and postoperative blood salvage devices were not effective as transfusion alternatives: use of these devices did not reduce erythrocyte use and increased costs.

  1. Is wartime mobilisation a suitable policy model for rapid national climate mitigation?

    International Nuclear Information System (INIS)

    Delina, Laurence L.; Diesendorf, Mark

    2013-01-01

    Climate science suggests that, to have a high probability of limiting global warming to an average temperature increase of 2 °C, global greenhouse gas emissions must peak by 2020 and be reduced to close to zero by 2040. However, the current trend is heading towards at least 4 °C by 2100 and little effective action is being taken. This paper commences the process of developing contingency plans for a scenario in which a sudden major global climate impact galvanises governments to implement emergency climate mitigation targets and programs. Climate activists assert that rapid mitigation is feasible, invoking the scale and scope of wartime mobilisation strategies. This paper draws upon historical accounts of social, technological and economic restructurings in several countries during World War 2 in order to investigate potential applications of wartime experience to radical, rigorous and rapid climate mitigation strategies. We focus on the energy sector, the biggest single contributor to global climate change, in developed and rapidly developing countries. We find that, while wartime experience suggests some potential strategies for rapid climate mitigation in the areas of finance and labour, it also has severe limitations, resulting from its lack of democratic processes. - Highlights: • The paper explores the strengths and weaknesses of using wartime experience as a model for rapid climate mitigation. • Wartime experience suggests some potential strategies for rapid climate mitigation in the areas of finance and labour. • Wartime experience also has severe limitations, resulting from its lack of democratic processes

  2. Data Policy

    Full Text Available The first purpose of data policy should be to serve the objectives of the organization or project sponsoring the collection of the data. With research data, data policy should also serve the broader goals of advancing scientific and scholarly inquiry and society at large. This is especially true with government-funded data, which likely comprise the vast majority of research data. Data policy should address multiple issues, depending on the nature and objectives of the data. These issues include data access requirements, data preservation and stewardship requirements, standards and compliance mechanisms, data security issues, privacy and ethical concerns, and potentially even specific collection protocols and defined data flows. The specifics of different policies can vary dramatically, but all data policies need to address data access and preservation. Research data gain value with use and must therefore be accessible and preserved for future access. This article focuses on data access. While policy might address multiple issues, at a first level it must address where the data stand on what Lyon (2009 calls the continuum of openness. Making data as openly accessible as possible provides the greatest societal benefit, and a central purpose of data policy is to work toward ethically open data access. An open data regime not only maximizes the benefit of the data, it also simplifies most of the other issues around effective research data stewardship and infrastructure development.

  3. The suitability of EDXRF for compositional classification of archaeological pottery

    International Nuclear Information System (INIS)

    Padilla Alvarez, Roman

    2007-01-01

    Many investigations have been carried out trying to enlarge the information that can be gathered through the chemical analysis of archaeological findings. Chemical composition data sets, properly interpreted with multivariate analysis techniques, have been used extensively to supplement investigations involving provenance studies or more complex socio-economic aspects of the past communities. Correct inferences from the gathered compositional data are only possible if well documented background information about the studied samples is available, such as a correct interpretation of the archaeological contexts, knowledge about the nature of the used raw materials or procurement sources (geology of the territories), among others. The combined use of Instrumental Neutron Activation Analysis (INAA) and Scanning Electron Microscopy X-ray analysis (SEM-EDX) has been widely applied to the classification of archaeological pottery. However the need to remove at least a minimal part (invasion) of the sample and the time delay required for radioisotope decay and the high costs involved in INAA often restrict its use. Energy Dispersive x-ray Fluorescence spectrometry (EDXRF) is advantageous to perform a completely non-destructive analysis in a relatively fast way, but several problems have restricted its wider use in the past. The highly matrix-dependent attenuation of x-rays in the analysed sample hampers the use of the standard-less quantification procedures as an alternative when suitable certified reference materials are not at hand, and the relatively limited instrumental sensitivity of the conventional spectrometers has not allowed the determination of some trace elements that are relevant for compositional differentiation and provided a comparatively higher uncertainties. This contribution presents the results of several investigations aimed to achieving classification of archaeological pottery using reliable quantitative EDXRF procedures. The main factors affecting the

    With the introduction of the Medicare Access and Children's Health Insurance Program Reauthorization Act, clinicians who are not eligible for an exemption must choose to participate in 1 of 2 new reimbursement models: the Merit-based Incentive Payment System or Alternative Payment Models (APMs). Although most dermatologists are expected to default into the Merit-based Incentive Payment System, some may have an interest in exploring APMs, which have associated financial incentives. However, for dermatologists interested in the APM pathway, there are currently no options other than joining a qualifying Accountable Care Organization, which make up only a small subset of Accountable Care Organizations overall. As a result, additional APMs relevant to dermatologists are needed to allow those interested in the APMs to explore this pathway. Fortunately, the Medicare Access and Children's Health Insurance Program Reauthorization Act establishes a process for new APMs to be approved and the creation of bundled payments for skin diseases may represent an opportunity to increase the number of APMs available to dermatologists. In this article, we will provide a detailed review of APMs under the Medicare Access and Children's Health Insurance Program Reauthorization Act and discuss the development and introduction of APMs as they pertain to dermatology.

  12. Modeling water scarcity and droughts for policy adaptation to climate change in arid and semiarid regions

    Science.gov (United States)

    Kahil, Mohamed Taher; Dinar, Ariel; Albiac, Jose

    2015-03-01

    Growing water extractions combined with emerging demands for environment protection increase competition for scarce water resources worldwide, especially in arid and semiarid regions. In those regions, climate change is projected to exacerbate water scarcity and increase the recurrence and intensity of droughts. These circumstances call for methodologies that can support the design of sustainable water management. This paper presents a hydro-economic model that links a reduced form hydrological component, with economic and environmental components. The model is applied to an arid and semiarid basin in Southeastern Spain to analyze the effects of droughts and to assess alternative adaptation policies. Results indicate that drought events have large impacts on social welfare, with the main adjustments sustained by irrigation and the environment. The water market policy seems to be a suitable option to overcome the negative economic effects of droughts, although the environmental effects may weaken its advantages for society. The environmental water market policy, where water is acquired for the environment, is an appealing policy to reap the private benefits of markets while protecting ecosystems. The current water management approach in Spain, based on stakeholders' cooperation, achieves almost the same economic outcomes and better environmental outcomes compared to a pure water market. These findings call for a reconsideration of the current management in arid and semiarid basins around the world. The paper illustrates the potential of hydro-economic modeling for integrating the multiple dimensions of water resources, becoming a valuable tool in the advancement of sustainable water management policies.

    2018-02-01

    National public health policies in Norway are based on a Health in All Policies (HiAP) approach. At the local level, this means that public health, as a cross-sectional responsibility, should be implemented in all municipal sectors by integrating public health policies in municipal planning and management systems. The paper investigates these local processes, focusing on the use of public health terminology and how this terminology is translated from national to local contexts. We ask whether the terms 'public health' and 'public health work' are suitable when implementing an HiAP approach. A qualitative case study based on analyses of interviews and planning documents was performed in three Norwegian municipalities. The results present dilemmas associated with using public health terminology when implementing an HiAP approach. On the one hand, the terms are experienced as wide, complex, advanced and unnecessary. On the other hand, the terms are experienced as important for a systematic approach towards understanding public health ideology and cross-sectional responsibility. One municipality used alternative terminology. This paper promotes debate about the appropriateness of using the terms 'public health' and 'public health work' at the local level. It suggests that adaptation is suitable and necessary, unless it compromises knowledge, responsibility and a systematic approach. This study concludes that the use of terminology is a central factor when implementing the Norwegian Public Health Act at the local level.

    The Environmental Policy Analysis Program was established to improve the formation of energy development and environmental policies with due mutual regard for national environmental and energy development needs. As a separate office under the Assistant Secretary for Environment, the program is implemented by the Director and by Offices of Environmental Policy Analysis in the eight DOE multiprogram laboratories. The program provides the Assistant Secretary with information on alternatives for decision making and early warning of environmental problems and considerations that may affect energy policy decisions. The program is intended to be a continuing activity, with its scope determined progressively as issues are defined. During FY-1977 the program focused on information compilation on levels of Pu and other transuranic elements in soils that would render the area unsafe for unlimited use; the impact of water pollution control laws on energy technologies; an analysis of the comparative health risks associated with various energy technologies; and the cost and related impacts on the nuclear industry arising from changes in radiation standards during the past 15 years

    Energy Technology Data Exchange (ETDEWEB)

    1995-01-01

    In recent years, gasoline and diesel fuel have accounted for about 80 percent of total transportation fuel and nearly all of the fuel used in on-road vehicles. Growing concerns about the environmental effects of fossil fuel use and the Nation`s high level of dependence on foreign oil are providing impetus for the development of replacements or alternatives for these traditional transportation fuels. (The Energy Policy Act of 1992 definitions of {open_quotes}replacement{close_quotes} and {open_quotes}alternative{close_quotes} fuels are presented in the following box.) The Alternative Motor Fuels Act of 1988, the Clean Air Act Amendments of 1990 (CAAA90) and the Energy Policy Act of 1992 (EPACT) are significant legislative forces behind the growth of replacement fuel use. Alternatives to Traditional Transportation Fuels 1993 provides the number of on-road alternative fueled vehicles in use in the United States, alternative and replacement fuel consumption, and information on greenhouse gas emissions resulting from the production, delivery, and use of replacement fuels for 1992, 1993, and 1995.

    Full Text Available Camelina (Camelina sativa L. is an oilseed with potential for use as a raw material in second-generation biofuels. Camelina has a seed yield of up to 2380 kg·ha−1 and contains around 45% fatty acids. Selection of a suitable site is critical for production optimization. The objective of this study was to determine Chilean agro-climatic suitability for establishing camelina as a productive alternative. Climate and soil requirements and geographical restraints were evaluated for the species, considering the climatological characteristics of its regions of origin, as well as regions where camelina is successfully grown in the rest of the world. The variables considered included factors (maximum temperatures of the warmest month, water deficits, and degree days and limitations (altitude, geomorphology, and current land use, which permitted the evaluation of the national territory for a certain level of suitability. It was determined that 1.3% of the national territory (960,664 ha has some degree of suitability for camelina adoption. Between the Biobío and Los Lagos regions, 49.0% of the land (471,203 ha is in the category of no thermic restrictions, with mild water restrictions, and mild soil restrictions or without information, which can be used for camelina production. The Los Ríos region has 21.4% surface area (321,176 ha with some level of suitability for camelina, the most suitable region to establish this crop in Chile.

    The main goal of this research was to establish a spatial model for identification of suitable land for cotton in Punjab, Pakistan through evaluation of multidisciplinary variables by applying geographic information system (GIS) and analytical hierarchy process (AHP) approach. In this model, rivers were used as constraint and seven factors were temperature, soil physical and chemical properties, soil pH, aridity classes, agro-ecological zones, and river command area. On the basis of these parameters suitability maps were generated. By pair-wise comparison matrix (PWCM) of AHP, weights were extracted by means of principal Eigen vector by Saaty method, with accepted consistency ratio of 0.09. Multi-criteria evaluation (MCE) employing weighted linear combination aggregates all suitability maps to generate final suitability map. It was found that more potential sites exist along with existing cotton practiced area. The result provided important information for farmers to establish linkage between policy decisions and regulatory actions and to improve agricultural land management. (author)

    Full Text Available This study examines the legal framework for ocean current energy policy and regulation to develop a metric for assessing the biological and geological characteristics of a seabed area with respect to the siting of OCE devices, a framework of criteria by which to assess seabed suitability (seabed suitability framework that can facilitate the siting, and implementation of ocean current energy (OCE projects. Seafloor geology and benthic biological data were analyzed in conjunction with seafloor core sample geostatistical interpolation to locate suitable substrates for OCE anchoring. Existing submarine cable pathways were considered to determine pathways for power transmission cables that circumvent biologically sensitive areas. Suitability analysis indicates that areas east of the Miami Terrace and north of recently identified deep-sea coral mounds are the most appropriate for OCE siting due to abundance of sand/sediment substrate, existing underwater cable route access, and minimal biological presence (i.e., little to no benthic communities. Further reconnaissance requires higher resolution maps of geological substrate and benthic community locations to identify specific OCE development locations, classify benthic conditions, and minimize potentially negative OCE environmental impacts.

    We discuss two alternative methods, based on the Lindstedt-Poincare technique, for the removal of secular terms from the equations of perturbation theory. We calculate the period of an anharmonic oscillator by means of both approaches and show that one of them is more accurate for all values of the coupling constant. We believe that present discussion and comparison may be a suitable exercise for teaching perturbation theory in advanced undergraduate courses on classical mechanics

    On the relation between the suitable environment and the distribution areas of Carya cathayensis Sarg., the current studies are mainly committed to qualitative descriptions, but did not consider quantitative models. The objective of this study was to establish a environment-suitability evaluation model which used to predict potential suitable areas of C. cathayensis. Firstly, the 3 factor data of soil type, soil parent material and soil thickness were obtained based on 2-class forest resource survey, and other factor data, which included elevation, slope, aspect, surface curvature, humidity index, and solar radiation index, were extracted from DEM (Digital Elevation Model). Additionally, the key affecting factors were defined by PCA (Principal Component Analysis), the weights of evaluation factors were determined by AHP (Analysis Hierarchy Process) and the quantitative classification of single factor was determined by membership function with fuzzy mathematics. Finally, a comprehensive environment-suitability evaluation model was established and which was also used to predict the potential suitable areas of C. cathayensis in Daoshi Town in the study region. The results showed that 85.6% of actual distribution areas were in the most suitable and more suitable regions and 11.5% in the general suitable regions

    To investigate the readability and suitability of sexual health promotion leaflets. Application of SMOG, FRY and SAM tests to assess the readability and suitability of a selection of sexual health leaflets. SMOG and FRY scores illustrate an average reading level of grade 9. SAM scores indicate that 59% of leaflets are superior in design and 41% are average in design. Leaflets generally perform well in the categories of content, literacy demand, typography and layout. They perform poorly in use of graphics, learning stimulation/motivation and cultural appropriateness. Sexual health leaflets have a reading level that is too high. Leaflets perform well on the suitability scores indicating they are reasonably suitable. There are a number of areas where sexual health leaflets could improve their design. Numerous practical techniques are suggested for improving the readability and suitability of sexual health leaflets. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available The main objective of this paper isto highlight the dynamics, diversity and especially the availability of an alternative financial market, developed outside of the traditional banking system, on online trading platforms, a market that can constitute an efficient solution, at the expense of entities open to fast funding, wide raging, with limited guaranties and minimum procedural and legislative formalities. For this purpose, we shall analyze briefly the main alternative financing methods, both empirically and qualitatively, in terms of similarities and differences between the two of them, inclusively of the amount that can be employed in this process through different methods. The current paper aims to be a practical guide meant to support those facing difficulties in obtaining financing for start-ups, implementing or/and developing business and entrepreneurship initiatives, and also a guide for those who want to be informed regarding the latest funding techniques. Another aspect to be considered is the legal framework in which this process takes place, because the regulation for these levers remains constantly behind the development process of new methods. The classic financiers should also consider reviewing the lending policy as the amounts attracted and accessed through these alternative methods increase exponentially from one year to the other, the volume of sums involved surpassing each time the forecasts, making thus possible the transformations of these paradigms from the financial sector into preponderant financial funding’s.

    Full Text Available Terrestrial long-distance migrations are declining globally: in North America, nearly 75% have been lost. Yet there has been limited research comparing habitat suitability and connectivity models to identify migration corridors across increasingly fragmented landscapes. Here we use pronghorn (Antilocapra americana migrations in prairie habitat to compare two types of models that identify habitat suitability: maximum entropy (Maxent and expert-based (Analytic Hierarchy Process. We used distance to wells, distance to water, NDVI, land cover, distance to roads, terrain shape and fence presence to parameterize the models. We then used the output of these models as cost surfaces to compare two common connectivity models, least-cost modeling (LCM and circuit theory. Using pronghorn movement data from spring and fall migrations, we identified potential migration corridors by combining each habitat suitability model with each connectivity model. The best performing model combination was Maxent with LCM corridors across both seasons. Maxent out-performed expert-based habitat suitability models for both spring and fall migrations. However, expert-based corridors can perform relatively well and are a cost-effective alternative if species location data are unavailable. Corridors created using LCM out-performed circuit theory, as measured by the number of pronghorn GPS locations present within the corridors. We suggest the use of a tiered approach using different corridor widths for prioritizing conservation and mitigation actions, such as fence removal or conservation easements.

    Participants in the Seminar on Population Policies for Top-level Policy Makers and Program Managers, meeting in Thailand during January 1987, examined the challenges now facing them regarding the implementation of fertility regulation programs in their respective countries -- Bangladesh, China, India, Indonesia, Malaysia, Nepal, Pakistan, the Philippines, the Republic of Korea, and Thailand. This Seminar was organized to coincide with the completion of an Economic and Social Commission for Asia and the Pacific (ESCAP) study investigating the impact and efficiency of family planning programs in the region. Country studies were reviewed at the Seminar along with policy issues about the status of women, incentive and disincentive programs, and socioeconomic factors affecting fertility. In Bangladesh the government recognizes population growth as its top priority problem related to the socioeconomic development of the country and is working to promote a reorientation strategy from the previous clinic-oriented to a multidimensional family welfare program. China's family planning program seeks to postpone marraige, space the births of children between 3-5 years, and promote the 1-child family. Its goal is to reduce the rate of natural increase from 12/1000 in 1978 to 5/1000 by 1985 and 0 by 2000. India's 7th Five-Year-Plan (1986-90) calls for establishing a 2-child family norm by 2000. In Indonesia the government's population policy includes reducing the rate of population growth, achieving a redistribution of the population, adjusting economic factors, and creating prosperous families. The government of Indonesia reversed its policy to reduce the population growth rate in 1984 and announced its goal of achieving a population of 70 million by 2100 in order to support mass consumption industries.

  18. A methodology for assessing the market benefits of alternative motor fuels: The Alternative Fuels Trade Model

    Energy Technology Data Exchange (ETDEWEB)

    Leiby, P.N.

    1993-09-01

    This report describes a modeling methodology for examining the prospective economic benefits of displacing motor gasoline use by alternative fuels. The approach is based on the Alternative Fuels Trade Model (AFTM). AFTM development was undertaken by the US Department of Energy (DOE) as part of a longer term study of alternative fuels issues. The AFTM is intended to assist with evaluating how alternative fuels may be promoted effectively, and what the consequences of substantial alternative fuels use might be. Such an evaluation of policies and consequences of an alternative fuels program is being undertaken by DOE as required by Section 502(b) of the Energy Policy Act of 1992. Interest in alternative fuels is based on the prospective economic, environmental and energy security benefits from the substitution of these fuels for conventional transportation fuels. The transportation sector is heavily dependent on oil. Increased oil use implies increased petroleum imports, with much of the increase coming from OPEC countries. Conversely, displacement of gasoline has the potential to reduce US petroleum imports, thereby reducing reliance on OPEC oil and possibly weakening OPEC`s ability to extract monopoly profits. The magnitude of US petroleum import reduction, the attendant fuel price changes, and the resulting US benefits, depend upon the nature of oil-gas substitution and the supply and demand behavior of other world regions. The methodology applies an integrated model of fuel market interactions to characterize these effects.

    The Government of Nepal has identified opportunities in agricultural commercialization, responding to a growing internal demand and expansion of export markets to reduce the immense trade deficit. Several cash crops, including coffee and bananas, have been identified in the recently approved Agriculture Development Strategy. Both of these crops have encouraged smallholder farmers to convert their subsistence farming practices to more commercial cultivation. Identification of suitable agro-ecological zones and understanding climate-related issues are important for improved production and livelihoods of smallholder farmers. Here, the suitability of coffee and banana crops is analyzed for different agro-ecological zones represented by Global Environmental Stratification (GEnS). Future shifts in these suitability zones are also predicted. Plantation sites in Nepal were geo-referenced and used as input in species distribution modelling. The multi-model ensemble model suggests that climate change will reduce the suitable growing area for coffee by about 72% across the selected emission scenarios from now to 2050. Impacts are low for banana growing, with a reduction in suitability by about 16% by 2050. Bananas show a lot of potential for playing an important role in Nepal as a sustainable crop in the context of climate change, as this study indicates that the amount of area suited to banana growing will grow by 40% by 2050. Based on our analysis we recommend possible new locations for coffee plantations and one method for mitigating climate change-related problems on existing plantations. These findings are expected to support planning and policy dialogue for mitigation and support better informed and scientifically based decision-making relating to these two crops. PMID:27689354

  1. German Energiewende and the heating market – Impact and limits of policy

    International Nuclear Information System (INIS)

    Bauermann, Klaas

    2016-01-01

    The German Energiewende envisages achieving a climate-neutral building stock in 2050 by means of two major pillars of regulation. First, residential buildings should consume 80% less primary energy and second; the remaining energy demand should be covered primarily with renewables. This paper simulates the future German heating market under different policy scenarios in order to evaluate the impact and limits of recent and conceivable policies. The investigation is based upon a dual model approach, linking a residential heating model to a discrete choice model. The major finding is that current regulations are not suitable for the achievement of governmental targets. Scenario calculations show that additional carbon emission reductions, triggered by the current regulatory regime, are falling short of expectations. In terms of economic efficiency, all calculated policy alternatives outperform the regulation currently in place. This allows to draw the conclusion that carbon emission reductions can be achieved without a major increase in cost. The model results highlight two policy implications. First, a rising mandatory share of renewables in the heating market is needed for target achievement and can be cost effectively. Second, renewable obligations for heating systems must include the existing building stock to achieve the postulated political targets. - Highlights: •The residential heating market accounts for major share of carbon emissions. •The disregard of the building stock weakens the impact of recent regulation. •Current regulation preserves a heating market dominated by fossil fuels. •A significant renewable share can be achieved through direct regulation. •Alternative policy leads to emission reductions without major increases in costs.

    Decision analysis-a systematic approach to solving complex problems-offers tools and frameworks to support decision making that are increasingly being applied to environmental challenges. Alternatives analysis is a method used in regulation and product design to identify, compare, and evaluate the safety and viability of potential substitutes for hazardous chemicals. We assessed whether decision science may assist the alternatives analysis decision maker in comparing alternatives across a range of metrics. A workshop was convened that included representatives from government, academia, business, and civil society and included experts in toxicology, decision science, alternatives assessment, engineering, and law and policy. Participants were divided into two groups and were prompted with targeted questions. Throughout the workshop, the groups periodically came together in plenary sessions to reflect on other groups' findings. We concluded that the further incorporation of decision science into alternatives analysis would advance the ability of companies and regulators to select alternatives to harmful ingredients and would also advance the science of decision analysis. We advance four recommendations: a ) engaging the systematic development and evaluation of decision approaches and tools; b ) using case studies to advance the integration of decision analysis into alternatives analysis; c ) supporting transdisciplinary research; and d ) supporting education and outreach efforts. https://doi.org/10.1289/EHP483.

    The aim of this study was to analyse the content, design, and readability of printed hearing aid user guides to determine their suitability for older adults, who are the main users of hearing aids. Hearing aid user guides were assessed using four readability formulae and a standardized tool to assess content and design (SAM - Suitability Assessment of Materials). A sample of 36 hearing aid user guides (four user guides from nine different hearing aid manufacturers) were analysed. Sixty nine percent of user guides were rated 'not suitable' and 31% were rated 'adequate' for their suitability. Many scored poorly for scope, vocabulary, aspects of layout and typography, and learning stimulation and motivation. The mean reading grade level for all user guides was grade 9.6 which is too high for older adults. The content, design, and readability of hearing aid user guides are not optimal for older adults and thus may serve as a barrier to successful hearing aid outcomes for this population.

    Gasoline consumption by passenger cars and light trucks is a major source of air pollution. It also adds to the economy's dependence on petroleum and vulnerability to oil price shocks. Despite these environmental and other costs, called external cost, the price of gasoline, adjusted for inflation, has generally been declining since 1985, encouraging increased consumption. This paper reports that with these concerns in mind, the Chairman, Subcommittee on Environment, House Committee on Science, Space, and Technology, requested that GAO assess policy options for addressing the external costs of gasoline consumption. To do this, GAO identified six major policy options and evaluated whether they addressed several relevant objectives, including economic growth, environmental quality, equity, petroleum conservation, visibility of costs, energy security, traffic congestion, competitiveness, and administrative feasibility

    Full Text Available In this study we propose a novel method for the estimation of ecological indices describing the habitat suitability of brown trout (Salmo trutta. Traditional hydrological tools are coupled with an innovative regional geostatistical technique, aiming at the prediction of the brown trout habitat suitability index where partial or totally ungauged conditions occur. Several methods for the assessment of ecological indices are already proposed in the scientific literature, but the possibility of exploiting a geostatistical prediction model, such as Topological Kriging, has never been investigated before. In order to develop a regional habitat suitability model we use the habitat suitability curve, obtained from measured data of brown trout adult individuals collected in several river basins across the USA. The Top-kriging prediction model is then employed to assess the spatial correlation between upstream and downstream habitat suitability indices. The study area is the Metauro River basin, located in the central part of Italy (Marche region, for which both water depth and streamflow data were collected. The present analysis focuses on discharge values corresponding to the 0.1-, 0.5-, 0.9-empirical quantiles derived from flow-duration curves available for seven gauging stations located within the study area, for which three different suitability indices (i.e. ψ10, ψ50 and ψ90 are evaluated. The results of this preliminary analysis are encouraging showing Nash-Sutcliffe efficiencies equal to 0.52, 0.65, and 0.69, respectively.

    Existing modeling approaches are divided between a focus on the constitutive (micro) elements of systems or on higher (macro) organization levels. Micro-level models enable consideration of individual histories and interactions, but can be unstable and subject to cumulative errors. Macro-level models focus on average population properties, but may hide relevant heterogeneity at the micro-scale. We present a framework that integrates both approaches through the use of temporally structured matrices that can take large numbers of variables into account. Matrices are composed of several bidimensional (time×age) grids, each representing a state (e.g. physiological, immunological, socio-demographic). Time and age are primary indices linking grids. These matrices preserve the entire history of all population strata and enable the use of historical events, parameters and states dynamically in the modeling process. This framework is applicable across fields, but particularly suitable to simulate the impact of alternative immunization policies. We demonstrate the framework by examining alternative strategies to accelerate measles elimination in 15 developing countries. The model recaptured long-endorsed policies in measles control, showing that where a single routine measles-containing vaccine is employed with low coverage, any improvement in coverage is more effective than a second dose. It also identified an opportunity to save thousands of lives in India at attractively low costs through the implementation of supplementary immunization campaigns. The flexibility of the approach presented enables estimating the effectiveness of different immunization policies in highly complex contexts involving multiple and historical influences from different hierarchical levels.

    The Internet is now widely regarded as essential infrastructure for our global economy and society. It is in our homes and businesses. We use it to communicate and socialize, for research, and as a platform for E-commerce. In the late 1990s, much was predicted about what the Internet has become at present; but now, we have actual experience living with the Internet as a critical component of our everyday lives. Although the Internet has already had profound effects, there is much we have yet to realize. The present volume represents a third installment in a collaborative effort to highlight the all-encompassing, multidisciplinary implications of the Internet for public policy. The first installment was conceived in 1998, when we initiated plans to organize an international conference among academic, industry, and government officials to discuss the growing policy agenda posed by the Internet. The conference was hosted by the European Commission in Brussels in 1999 and brought together a diverse mix of perspectives on what the pressing policy issues would be confronting the Internet. All of the concerns identified remain with us today, including how to address the Digital Divide, how to modify intellectual property laws to accommodate the new realities of the Internet, what to do about Internet governance and name-space management, and how to evolve broadcast and telecommunications regulatory frameworks for a converged world.

    Full Text Available In many countries of the world investments are made for obtaining energy efficiency, pursuing to increase the generation of non-polluting fuels due to the fact that energy is vital for any economy. The increase in non-polluting fuels and in renewable energy generation might lead to diminishing the dependence of countries less endowed with conventional energy resources on oil and natural gas from Russia or from Arab countries. Nevertheless, environmental issues represent serious questions facing the mankind, requiring the identification, prevention, and why not, their total solving.European Union countries depend on imports of energy, especially on oil imports. At the same time, the European Union countries record a high volume of greenhouse gas emissions, substances adding to global warming. The transport sector is the main consumer of fossil fuels and generator of greenhouse gas emissions. Therefore, diversifying the energy supply used in the transport sector with less polluting sources is an essential objective of the European Union policy in the transport, energy and environment sector. Road transports’ is the sector recording the highest consumption of energy and the highest volume of greenhouse gas emissions.The use of ecologic fuels in the transport sector is an important factor for achieving the objectives of European policies in the field. It is yet to be seen to what extent alternative energy sources are damaging to the environment, as it is a known fact that even for them is recorded a certain level of negative externalities.

  15. Alternative Energy Development and China's Energy Future

    2011-06-15

    In addition to promoting energy efficiency, China has actively pursued alternative energy development as a strategy to reduce its energy demand and carbon emissions. One area of particular focus has been to raise the share of alternative energy in China’s rapidly growing electricity generation with a 2020 target of 15% share of total primary energy. Over the last ten years, China has established several major renewable energy regulations along with programs and subsidies to encourage the growth of non-fossil alternative energy including solar, wind, nuclear, hydro, geothermal and biomass power as well as biofuels and coal alternatives. This study thus seeks to examine China’s alternative energy in terms of what has and will continue to drive alternative energy development in China as well as analyze in depth the growth potential and challenges facing each specific technology. This study found that despite recent policies enabling extraordinary capacity and investment growth, alternative energy technologies face constraints and barriers to growth. For relatively new technologies that have not achieved commercialization such as concentrated solar thermal, geothermal and biomass power, China faces technological limitations to expanding the scale of installed capacity. While some alternative technologies such as hydropower and coal alternatives have been slowed by uneven and often changing market and policy support, others such as wind and solar PV have encountered physical and institutional barriers to grid integration. Lastly, all alternative energy technologies face constraints in human resources and raw material resources including land and water, with some facing supply limitations in critical elements such as uranium for nuclear, neodymium for wind and rare earth metals for advanced solar PV. In light of China’s potential for and barriers to growth, the resource and energy requirement for alternative energy technologies were modeled and scenario analysis

    Indonesia has been widely known as the best Arabica coffee (Coffea arabica) producer, in terms of both aspects, quality and number of product. Currently, its production, however, declines to the 3rd rank internationally. Issues emerged in the coffee cultivation are: land unsuitability, low quality of seeds, and poor management. Among Arabica coffee types, wild civet coffee is the most expensive one and harvested from the coffee beans which have been digested naturally. The study aims to determine the physical suitability of land as well as the constraints related to land for civet Arabica coffee in selected study cases, e.g., Bandung and Bandung Barat. The research methods employ multi-criteria analysis, and combined with weighted overlaying techniques for mapping. The criteria include temperature, rainfall, humidity, duration of dry season, slope, altitude, type of soil, soil texture, and erosion potential. Parameters of civet (Paradoxurus hermaphroditus) are land use, altitude, and temperature. Local policy strongly supports the extensive management for land and the increase of coffee export. Processing data involved matching the comparison between guideline requirements for the land suitability classes, characteristics of Arabica coffee and civet habitat. The results covered the profile suitable land of the civet Arabica coffee in the study areas.

    Over the last 30 years, the Asian tiger mosquito, Aedes albopictus, has rapidly spread around the world. The European distribution comprises the Mediterranean basin with a first appearance in Switzerland in 2003. Early identification of the most suitable areas in Switzerland allowing progressive invasion by this species is considered crucial to suggest adequate surveillance and control plans. We identified the most suitable areas for invasion and establishment of Ae. albopictus in Switzerland. The potential distribution areas linked to the current climatic suitability were assessed using remotely sensed land surface temperature data recorded by the MODIS satellite sensors. Suitable areas for adult survival and overwintering of diapausing eggs were also identified for future climatic conditions, considering two different climate change scenarios (A1B, A2) for the periods 2020-2049 and 2045-2074. At present, the areas around Lake Geneva in western Switzerland provide suitable climatic conditions for Ae. albopictus. In northern Switzerland, parts of the Rhine valley, around Lake Constance, as well as the surroundings of Lake Neuchâtel, appear to be suitable for the survival at least of adult Ae. albopictus. However, these areas are characterized by winters currently being too cold for survival and development of diapausing eggs. In southern Switzerland, Ae. albopictus is already well-established, especially in the Canton of Ticino. For the years 2020-2049, the predicted possible spread of the tiger mosquito does not differ significantly from its potential current distribution. However, important expansions are obtained if the period is extended to the years 2045-2074, when Ae. albopictus may invade large new areas. Several parts of Switzerland provide suitable climatic conditions for invasion and establishment of Ae. albopictus. The current distribution and rapid spread in other European countries suggest that the tiger mosquito will colonize new areas in Switzerland

    Full Text Available After 1989, the demographic situation of Romania population experienced a dramatic, very concerning and dangerous evolution trend. One of the first measures of the new political power was to abolish the very restrictive, anti-human and abusive legal regulation adopted in 1966 by the communist regime concerning abortion and the whole old demographic policy. As a result of this measure and of the worsening economic and social situation of the great majority of Romanian population, the birth rate declined sharply and, from 1992, the natural demographic growth rate became a negative one. The absolute number of Romanian population decreased more and more and, if nothing changes, in the next few decades it will be no bigger than 15 million people. At the same time, the process of demographic ageing of population will accentuate, generating serious problems from demographic and social-economic point of view, Taking into account the present demographic situation and, especially, the foreseen trend of evolution, it is more than clear that there should be taken some urgent, coherent and consistent measures in order to stop this dangerous demographic evolution, until it is not too late, and to avoid, as much as possible, a potential demographic disaster. The problem is: what kind of measures should be taken and what kind of policy should be adopted? Some social scientists believe that a new population policy should be adopted; some others believe that rather a social policy should be adopted. The purpose of my paper is to analyze this different opinions and to show that, behind the dispute on the terminology, should be taken consistent measures, at governmental level, in order to assure a substantial improvement of demographic situation, not only from a quantitative, but from a qualitative point of view as well, and to identify some of these kind of measures.

    Full Text Available Continuous gravity-fed column experiments using the methylene blue (MB discoloration method were performed to characterize the suitability of a pozzolan (PZ specimen as alternative admixing aggregate for metallic iron filters (Fe0-filters. Investigated systems were: (i pure sand, (ii pure PZ, (iii pure Fe0, (iv Fe0/sand, (v Fe0/PZ, and (vi Fe0/sand/PZ. The volumetric proportion of Fe0 was 25%. The volumetric proportions of the Fe0/sand/PZ system was 25/45/30. The initial MB concentration was 2.0 mg·L−1, 6.0 g of Fe0 was used, and the experiments lasted for 46 days. The individual systems were fed with 3.9 to 8.4 L (7.80 to 16.69 mg of MB and were characterized by the time-dependent changes of: (i the pH value, (ii the iron breakthrough, (iii the MB breakthrough, and (iv the hydraulic conductivity. Results showed that the Fe0/sand/PZ system was the most efficient. This ternary system was also the most permeable and therefore the most sustainable. The suitability of MB as a powerful operative indicator for the characterization of processes in the Fe0/H2O system was confirmed. The tested PZ is recommended as an alternative material for efficient but sustainable Fe0 filters.

    Habitat Suitability Index (SI) curves are one method of presenting species habitat suitability criteria. The curves are often used with the Habitat Evaluation Procedures (HEP) and are necessary components of the Instream Flow Incremental Methodology (IFIM) (Armour et al. 1984). Bovee (1986) described three categories of SI curves or habitat suitability criteria based on the procedures and data used to develop the criteria. Category I curves are based on professional judgment, with 1ittle or no empirical data. Both Category II (utilization criteria) and Category III (preference criteria) curves have as their source data collected at locations where target species are observed or collected. Having Category II and Category III curves for all species of concern would be ideal. In reality, no SI curves are available for many species, and SI curves that require intensive field sampling often cannot be developed under prevailing constraints on time and costs. One alternative under these circumstances is the development and interim use of SI curves based on expert opinion. The Delphi technique (Pill 1971; Delbecq et al. 1975; Linstone and Turoff 1975) is one method used for combining the knowledge and opinions of a group of experts. The purpose of this report is to describe how the Delphi technique may be used to develop expert-opinion-based SI curves.

    This paper presents an investigation of suitability natural fibre as replacement material for table tennis blade, due to low cost, lightweight and apparently environmentally. Nowadays, natural fibre are one of the materials often used in replaced the main material on manufacturing sector, such as automotive, and construction. The objective of this study is to investigate and evaluate the suitability natural fiber materials to replace wood as a structure on table tennis blade. The mechanical properties of the different natural fibre material were examined, and correlated with characteristic of table tennis blade. The natural fibre selected for the study are kenaf (Hibiscus Cannabinus), jute, hemp, sisal (Agave Sisalana) and ramie. A further comparison was made with the corresponding properties of each type of natural fiber using Quality Function Deployment (QFD) and Theory of Inventive Problem Solving (TRIZ). TRIZ has been used to determine the most appropriate solution in producing table tennis blade. The results showed the most appropriate solution in producing table tennis blade using natural fibre is kenaf natural fibre. The selected on suitability natural fibre used as main structure on table tennis blade are based on the characteristics need for good performance of table tennis blade, such as energy absorption, lightweight, strength and hardness. Therefore, it shows an opportunity for replacing existing materials with a higher strength, lower cost alternative that is environmentally friendly.

    Full Text Available The suitability of the soils surrounding the sugarcane plantation at "Herois de Caxito" (7068 ha is assessed. The main goal is to identify land suitability for the enlargement of the present plantation, using FAO land evaluation models (modified to suit Herois de Caxito conditions and GIS. Calculations of the radiationthermal production potential (RPP, land production potential (LPP, irrigation suitability index, and evaluation of the irrigation water quality are done. The water-limited production potential (WPP is found equal to the RPP, because water needs were fully met under irrigation. Maps showing the spatial distribution of the LPP and the suitability for irrigation are generated. The matching of irrigation and fertility indices has shown that, about 40% of the soils with good fertility for sugarcane production present low suitability for irrigation, the main limitations being the very fine texture and the drainage. The available surface water at Herois de Caxito (Dande river is of very good quality for irrigation of sugarcane.

    To study the ecological suitability regionalization of Eucommia ulmoides, for selecting artificial planting base and high-quality industrial raw material purchase area of the herb in Guizhou. Based on the investigation of 14 Eucommia ulmoides producing areas, pinoresinol diglucoside content and ecological factors were obtained. Using spatial analysis method to carry on ecological suitability regionalization. Meanwhile, combining pinoresinol diglucoside content, the correlation of major active components and environmental factors were analyzed by statistical analysis. The most suitability planting area of Eucommia ulmoides was the northwest of Guizhou. The distribution of Eucommia ulmoides was mainly affected by the type and pH value of soil, and monthly precipitation. The spatial structure of major active components in Eucommia ulmoides were randomly distributed in global space, but had only one aggregation point which had a high positive correlation in local space. The major active components of Eucommia ulmoides had no correlation with altitude, longitude or latitude. Using the spatial analysis method and statistical analysis method, based on environmental factor and pinoresinol diglucoside content, the ecological suitability regionalization of Eucommia ulmoides can provide reference for the selection of suitable planting area, artificial planting base and directing production layout.

    Regulative policy means those governmental attempts to steer the course of things which can fall back on a certain repertoire of instruments for actions in order to warrant the causal and temporal connection between the making available and the employment of means. The fact that environmental protection needs regulative policy is substantiated by the thesis that the market has failed; consequently only government can manage the public goods 'environment' in a suitable way, and it is a matter of fact that environmental protection at present is operated preferably via regulative policy. The problems of regulative enviromental policy are manifold. Its implementation often miscarries because of limited administrative resources on the one hand - making sufficient control impossible for instance -, and because of poor quality regulative instruments on the other hand. One way out would be to increase the efficiency of regulative policy by sophisticating judicial techniques. Other ways out point to the executing level and aim at improving implementation strategies or are concerned with post-regulative law. The latter refers to a new legal quality which demonstrates itself already in corporatistical crisis regulation or in induction programs such as pollution limits. A final way out favours deregulation strategies which includes the introduction of environmental levies or the allocation of environmental licences. An interdisciplinary discourse is to find out what would happen if these ways were taken. Pointers to solutions from varying scientific disciplines resulting from this discourse are to be found in this volume. (orig./HSCH).

    The HL-LHC parameters assume unexplored regimes for hadron colliders in various aspects of accelerator beam dynamics and technology. This paper reviews three alternatives that could potentially improve the LHC performance: (i) the alternative filling scheme 8b+4e, (ii) the use of a 200 MHz RF system in the LHC and (iii) the use of proton cooling methods to reduce the beam emittance (at top energy and at injection). The alternatives are assessed in terms of feasibility, pros and cons, risks versus benefits and the impact on beam availability.

    For the past ten years, alternative loop rings have intrigued mathematicians from a wide cross-section of modern algebra. As a consequence, the theory of alternative loop rings has grown tremendously. One of the main developments is the complete characterization of loops which have an alternative but not associative, loop ring. Furthermore, there is a very close relationship between the algebraic structures of loop rings and of group rings over 2-groups. Another major topic of research is the study of the unit loop of the integral loop ring. Here the interaction between loop rings and group ri

    Full Text Available In order to reduce soil erosion and desertification, the Sloping Land Conversion Program has been conducted in China for more than 15 years, and large areas of farmland have been converted to forest and grassland. However, this large-scale vegetation-restoration project has faced some key problems (e.g. soil drying that have limited the successful development of the current ecological-recovery policy. Therefore, it is necessary to know about the land use, vegetation, and soil, and their inter-relationships in order to identify the suitability of vegetation restoration. This study was conducted at the watershed level in the ecologically vulnerable region of the Loess Plateau, to evaluate the land suitability using the analytic hierarchy process (AHP. The results showed that (1 the area unsuitable for crops accounted for 73.3% of the watershed, and the main factors restricting cropland development were soil physical properties and soil nutrients; (2 the area suitable for grassland was about 86.7% of the watershed, with the remaining 13.3% being unsuitable; (3 an area of 3.95 km(2, accounting for 66.7% of the watershed, was unsuitable for forest. Overall, the grassland was found to be the most suitable land-use to support the aims of the Sloping Land Conversion Program in the Liudaogou watershed. Under the constraints of soil water shortage and nutrient deficits, crops and forests were considered to be inappropriate land uses in the study area, especially on sloping land. When selecting species for re-vegetation, non-native grass species with high water requirements should be avoided so as to guarantee the sustainable development of grassland and effective ecological functioning. Our study provides local land managers and farmers with valuable information about the inappropriateness of growing trees in the study area along with some information on species selection for planting in the semi-arid area of the Loess Plateau.

    In the early 1990s, the tight job market for Ph.D. recipients in physics led to a reexamination of graduate programs by some departments. The speaker participated in this reanalysis at his graduate institution and arranged presentations of alternative careers to the physics graduate student body. What became clear was that diverse options were open; job seekers just needed flexible expectations. However, there are a number of additions or modifications to graduate programs which could further help to prepare Ph.D. recipients as they move into non-traditional roles, such as additional and more formal experience in communicating science to a wide range of audiences. In particular, it would be advantageous to learn how to explain the role that basic scientific research projects play in the larger public policy arena. Examples from the speaker's experience of working as a staff member in the U.S. Congress will be presented to illustrate the skills needed in that environment.

    The author gives an overlapping socialpolitical history of the decision-making process on nuclear energy in the Federal Republic of Germany. He follows the path on which within about two decades an investment strategy planned in the long term by a few international multis has become the issue of the century at all political and economic levels and instances. The study analyses the conditions of the fact that a conflict has arisen, and of the conflict development within the political system of the Federal Republic of Germany. As a result, the author shows that the present conflict has been provoked by the systematic ruling-out of all those concerned who have contrary interests. The escalation of the conflict during the 70s has led to a paralysis of the political decision-making process, because neither existing policies nor distinct alternatives could be ca rried through.

    1990-01-01

    Although general relativity is a well-established discipline the theory deserves efforts aimed at producing alternative or more general frameworks for investigating the classical properties of gravity. These are either devoted to producing alternative viewpoints or interpretations of standard general relativity, or at constructing, discussing and proposing experimental tests for alternative descriptions of the dynamics of the gravitational field and its interaction (or unification) with external matter fields. Classical alternative theories of gravitation can roughly classified as follows; theories based on a still 4-dimensional picture, under the assumption that the dynamics of the gravitational field is more complicated than Einstein's and theories based on higher-dimensional pictures. This leads to supergravity and strings which are not included here. Theories based on higher-dimensional pictures on the assumption that space-time is replaced by a higher-dimensional manifold. Papers on these classifications are reviewed. (author)

Overall, the sealing system has the purpose of reducing to the extent possible the potential for fluids (either gas or liquid) from entering or leaving the repository. The sealing system is divided into three subsystems: drift and panel seals within the repository horizon, shaft seals in each of the four shafts, and borehole seals. Alternatives to the baseline configuration for the WIPP seal system design included evaluating different geometries and schedules for seal component installations and the use of different materials for seal components. Order-of-magnitude costs for the various alternatives were prepared as part of the study. Firm recommendations are not presented, but the advantages and disadvantages of the alternatives are discussed. Technical information deficiencies are identified and studies are outlined which can provide required information

    Full Text Available Ongoing climate change can alter conditions for plant growth, in turn affecting ecological and social systems. While there have been considerable advances in understanding the physical aspects of climate change, comprehensive analyses integrating climate, biological, and social sciences are less common. Here we use climate projections under alternative mitigation scenarios to show how changes in environmental variables that limit plant growth could impact ecosystems and people. We show that although the global mean number of days above freezing will increase by up to 7% by 2100 under "business as usual" (representative concentration pathway [RCP] 8.5, suitable growing days will actually decrease globally by up to 11% when other climatic variables that limit plant growth are considered (i.e., temperature, water availability, and solar radiation. Areas in Russia, China, and Canada are projected to gain suitable plant growing days, but the rest of the world will experience losses. Notably, tropical areas could lose up to 200 suitable plant growing days per year. These changes will impact most of the world's terrestrial ecosystems, potentially triggering climate feedbacks. Human populations will also be affected, with up to ~2,100 million of the poorest people in the world (~30% of the world's population highly vulnerable to changes in the supply of plant-related goods and services. These impacts will be spatially variable, indicating regions where adaptations will be necessary. Changes in suitable plant growing days are projected to be less severe under strong and moderate mitigation scenarios (i.e., RCP 2.6 and RCP 4.5, underscoring the importance of reducing emissions to avoid such disproportionate impacts on ecosystems and people.

    2014-02-01

    The incidence of drug abuse with alternative agents is increasing. The term "alternative drugs of abuse" is a catch-all term for abused chemicals that do not fit into one of the classic categories of drugs of abuse. The most common age group abusing these agents range from 17 to 25 years old and are often associated with group settings. Due to their diverse pharmacological nature, legislative efforts to classify these chemicals as a schedule I drug have lagged behind the development of new alternative agents. The potential reason for abuse of these agents is their hallucinogenic, dissociative, stimulant, anti-muscarinic, or sedative properties. Some of these drugs are easily obtainable such as Datura stramonium (Jimson Weed) or Lophophora williamsii (Peyote) because they are natural plants indigenous to certain regions. The diverse pharmacology and clinical effects of these agents are so broad that they do not produce a universal constellation of signs and symptoms. Detailed physical exams are essential for identifying clues leading one to suspect an alternative drug of abuse. Testing for the presence of these agents is often limited, and even when available, the results do not return in a timely fashion. Intoxications from these agents pose unique challenges for health care providers. Physician knowledge of the physiological effects of these alternative agents and the local patterns of drug of abuse are important for the accurate diagnosis and optimal care of poisoned patients. This review summarizes the current knowledge of alternative drugs of abuse and highlights their clinical presentations.

    The Coventry (Lanchester) Polytechnic Wave Energy Group has been involved in the United Kingdom wave energy research programme since its inception in 1975. Whilst the work of the group is mainly concerned with wave energy, and currently is directed towards the design of a wave energy device tailored to the needs of isolated/island communities, it has some involvement with other aspects of the alternatives. This conference, dealing with alternative energy systems and their electrical integration and utilisation was engendered by the general interest which the Polytechnic group members have in the alternatives and their use. The scope for electrical integration and utilisation is very broad. Energy for family groups may be provided in a relatively unsophisticated way which is acceptable to them. Small population centres, for example island communities relying upon diesel equipment, can reap the benefits of the alternatives through their ability to accept novel integration schemes and a flexible approach to the use of the energy available. Consumers already enjoying the benefits of a 'firm' electricity grid supply can use energy from a variety of alternative systems, via the grid, without having to modify their energy consumption habits. In addition to the domestic and industrial applications and coastal possibilities, specialist applications in isolated environments have also emerged. The Proceedings detail practical, technical and economic aspects of the alternatives and their electrical integration and utilisation.

    Then-President Gerald Ford outlines the potential benefits of nuclear power as opposed to the danger of proliferation. He points out that not all nations have the same interest or views toward nuclear energy; but also he says that if a choice must be made, nonproliferation objectives must take precedence over economic and energy benefits. It is pointed out that the management of nuclear energy can be only partial and temporary by technical measures, and that full management can result only if nations realistically face the task prepared to forego preconceived short-term advantages in favor of long-term gains. Coordination of the policies of all nations toward the common goal of nonproliferation is predicted to lead to success

    Full Text Available Stream control transmission protocol (SCTP is a transport layer protocol, which is efficient, reliable, and connection-oriented as compared to transmission control protocol (TCP and user datagram protocol (UDP. Additionally, SCTP has more innovative features like multihoming, multistreaming and unordered delivery. With multihoming, SCTP establishes multiple paths between a sender and receiver. However, it only uses the primary path for data transmission and the secondary path (or paths for fault tolerance. Concurrent multipath transfer extension of SCTP (CMT-SCTP allows a sender to transmit data in parallel over multiple paths, which increases the overall transmission throughput. Parallel data transmission is beneficial for higher data rates. Parallel transmission or connection is also good in services such as video streaming where if one connection is occupied with errors the transmission continues on alternate links. With parallel transmission, the unordered data packets arrival is very common at receiver. The receiver has to wait until the missing data packets arrive, causing performance degradation while using CMT-SCTP. In order to reduce the transmission delay at the receiver, CMT-SCTP uses intelligent retransmission polices to immediately retransmit the missing packets. The retransmission policies used by CMT-SCTP are RTX-SSTHRESH, RTX-LOSSRATE and RTX-CWND. The main objective of this paper is the performance analysis of the retransmission policies. This paper evaluates RTX-SSTHRESH, RTX-LOSSRATE and RTX-CWND. Simulations are performed on the Network Simulator 2. In the simulations with various scenarios and parameters, it is observed that the RTX-LOSSRATE is a suitable policy.

    Highlights: • Six intervals of additive noises divided according to the two constraints. • Derivation of the suitable additive noise to meet the two constraints. • Formulation of the suitable noise for improvability or nonimprovability. • Optimal noises to minimize P FA , maximize P D and maximize the overall improvement. - Abstract: We present an effective way to generate the suitable or the optimal additive noises which can achieve the three goals of the noise enhanced detectability, i.e., the maximum detection probability (P D ), the minimum false alarm probability (P FA ) and the maximum overall improvement of P D and P FA , without increasing P FA and decreasing P D in a binary hypothesis testing problem. The mechanism of our method is that we divide the discrete vectors into six intervals and choose the useful or partial useful vectors from these intervals to form the additive noise according to different requirements. The form of the optimal noise is derived and proven as a randomization of no more than two discrete vectors in our way. Moreover, how to choose suitable and optimal noises from the six intervals are given. Finally, numerous examples are presented to illustrate the theoretical analysis, where the background noises are Gaussian, symmetric and asymmetric Gaussian mixture noise, respectively.

  13. Alternatives to conventional evaluation of rideability in horse performance tests: suitability of rein tension and behavioural parameters.

    König von Borstel, Uta; Glißman, Chantal

    2014-01-01

    Rideability, i.e. the ease and comfort with which a horse can be ridden, is considered to be one of the most important traits in riding horses. However, at present rideability is evaluated rather subjectively in breeding horse performance tests. The aim of the present study was to evaluate the role horse behaviour as well as degree and quality of rein tension might play in judges' evaluation of horses' rideability. Mares (n=33) and stallions (n=13) from two different mare- and one stallion-testing station were observed twice during their performance test dressage training. During these rides, rein tension was measured continuously, and frequency of behaviour patterns such as head-tossing, tail swishing, and snorting was recorded. Rein tension parameters showed reasonable repeatabilities within horse-rider pairs (e.g. mean rein tension: r(2)=0.61 ± 0.11; variance of rein tension: r(2)=0.52 ± 0.14). Regression analysis revealed that a larger proportion of variance in rideability scores could be explained by maximum (17%), mean (16%) and variance (15%) of rein tension compared to horses' or riders' behavioural parameters (tail-swishing: 5% and rider's use of hands: 5%, respectively). According to mixed model analysis, rideability scores dropped (all Prein tension (e.g. -0.37 ± 0.14 scores per additional 10 Newton in mean tension). However, mean rein tension differed between testing stations (Prein tension is either directly or indirectly an important factor for judges to derive rideability scores. Given the importance of rein tension parameters to both rider comfort and horse welfare, potentially, measurements of rein tension along with behaviour observations assessing the quality of rein contact (e.g. distinguishing a light contact from attempts to evade contact) might be used to make the assessment of rideability more impartial.

    Full Text Available Yu-Guo Yuan,1 Yan-Hong Wang,1 Hui-Hui Xing,1 Sangiliyandi Gurunathan2 1Jiangsu Co-Innovation Center for Prevention and Control of Important Animal Infectious Diseases and Zoonosis, College of Veterinary Medicine, Yangzhou University, Yangzhou, Jiangsu, People’s Republic of China; 2Department of Stem Cell and Regenerative Biotechnology, Konkuk University, Seoul, Republic of Korea Background: Graphene and graphene-related materials have gained substantial interest from both academia and industry for the development of unique nanomaterials for biomedical applications. Graphene oxide (GO and silver nanoparticles (AgNPs are a valuable platform for the development of nanocomposites, permitting the combination of nanomaterials with different physical and chemical properties to generate novel materials with improved and effective functionalities in a single platform. Therefore, this study was conducted to synthesize a graphene oxide–silver nanoparticle (GO-AgNPs nanocomposite using the biomolecule quercetin and evaluate the potential cytotoxicity and mechanism of GO-AgNPs in human neuroblastoma cancer cells (SH-SY5Y.Methods: The synthesized GO-AgNPs were characterized using various analytical techniques. The potential toxicities of GO-AgNPs were evaluated using a series of biochemical and cellular assays. The expression of apoptotic and anti-apoptotic genes was measured by quantitative real-time reverse transcription polymerase chain reaction. Further, apoptosis was confirmed by caspase-9/3 activity and a terminal deoxynucleotidyl transferase dUTP nick end labeling assay, and GO-AgNPs-induced autophagy was also confirmed by transmission electron microscopy.Results: The prepared GO-AgNPs exhibited significantly higher cytotoxicity toward SH-SY5Y cells than GO. GO-AgNPs induced significant cytotoxicity in SH-SY5Y cells by the loss of cell viability, inhibition of cell proliferation, increased leakage of lactate dehydrogenase, decreased level of mitochondrial membrane potential, reduced numbers of mitochondria, enhanced level of reactive oxygen species generation, increased expression of pro-apoptotic genes, and decreased expression of anti-apoptotic genes. GO-AgNPs induced caspase-9/3-dependent apoptosis via DNA fragmentation. Finally, GO-AgNPs induced accumulation of autophagosomes and autophagic vacuoles.Conclusion: In this study, we developed an environmentally friendly, facile, dependable, and simple method for the synthesis of GO-AgNPs nanocomposites using quercetin. The synthesized GO-AgNPs exhibited enhanced cytotoxicity compared with that of GO at very low concentrations. This study not only elucidates the potential cytotoxicity against neuroblastoma cancer cells, but also reveals the molecular mechanism of toxicity.

  17. Reassessing nuclear nonproliferation policy

    International Nuclear Information System (INIS)

    Smith, G.; Rathjens, G.

    1981-01-01

    Unresolved proliferation problems are as serious issues for the Reagan Administration as East-West relations and dependence on imported oil. The linkage of nuclear weapons to power reactors is debatable, but developing and industrialized countries alike feel that nuclear power is an important option. A review of Carter policies finds them flawed in several respects. Although they heightened worldwide concern about proliferation, they fell short because (1) most governments and the nuclear industry reacted negatively; (2) they offered no way to deal with countries which construct only weapons facilities; (3) they did not help the US image as a reliable supplier; (4) no realistic fuel-cycle alternatives emerged; and (5) little has been done about fuel assurances and international spent-fuel storage. Past policies need to be restructured under new premises to deal effectively with the motivation to acquire nuclear weapons. The effort should stress collective rather than unilateral action and a renewed effort for a comprehensive test ban treaty. 10 references

    Over 72% of Americans use online health information to assist in health care decision-making. Previous studies of lymphedema literature have focused only on reading level of patient-oriented materials online. Findings indicate they are too advanced for most patients to comprehend. This, more comprehensive study, expands the previous analysis to include critical elements of health materials beyond readability using assessment tools to report on the complexity and density of data as well as text design, vocabulary, and organization. The top 10 highest ranked websites on lymphedema were identified using the most popular search engine (Google). Website content was analyzed for readability, complexity, and suitability using Simple Measure of Gobbledygook, PMOSE/iKIRSCH, and Suitability Assessment of Materials (SAM), respectively. PMOSE/iKIRSCH and SAM were performed by two independent raters. Fleiss' kappa score was calculated to ensure inter-rater reliability. Online lymphedema literature had a reading grade level of 14.0 (SMOG). Overall complexity score was 6.7 (PMOSE/iKIRSCH) corresponding to "low" complexity and requiring a 8th-12th grade education. Fleiss' kappa score was 80% (P = 0.04, "substantial" agreement). Overall suitability score was 45% (SAM) correlating to the lowest level of "adequate" suitability. Fleiss' kappa score was 76% (P = 0.06, "substantial" agreement). Online resources for lymphedema are above the recommended levels for readability and complexity. The suitability level is barely adequate for the intended audience. Overall, these materials are too sophisticated for the average American adult, whose literacy skills are well documented. Further efforts to revise these materials are needed to improve patient comprehension and understanding. Copyright © 2017 Elsevier Inc. All rights reserved.

  19. Alternative fuels for vehicles; Alternative drivmidler

    Energy Technology Data Exchange (ETDEWEB)

    2012-02-15

    Up until 2020 and onwards the analysis indicates that especially electricity, biogas and natural gas as propellants is economically attractive compared to conventional gasoline and diesel while other fuels have the same or higher costs for petrol and diesel. Especially biogas and electricity will also offer significant reductions in CO{sub 2} emissions, but also hydrogen, methanol, DME and to a lesser extent the second generation bioethanol and most of the other alternative fuels reduce CO{sub 2} emissions. Use of the traditional food-based first generation biofuels involves, at best, only modest climate benefits if land use changes are counted, and at worst, significant negative climate effects. Natural gas as a propellant involves a moderate climate gain, but may play a role for building infrastructure and market for gaseous fuels in large fleets, thereby contributing to the phasing in of biogas for transport. The electric-based automotive fuels are the most effective due to a high efficiency of the engine and an increasing proportion of wind energy in the electricity supply. The methanol track also has a relatively high efficiency. Among the others, the track based on diesel engines (biodiesel) is more effective than the track based on gasoline/Otto engines (gas and ethanol) as a result of the diesel engine's better efficiency. For the heavy vehicles all the selected alternative fuels to varying degrees reduce emissions of CO{sub 2}, particularly DME based on wood. The only exception to this is - as for passenger cars - the propellant synthetic diesel based on coal. (LN).

    This study evaluated the technical suitability of Yucca Mountain, Nevada, as a potential site for a mined geologic repository for the permanent disposal of radioactive waste. The evaluation was conducted primarily to determine early in the site characterization program if there are any features or conditions at the site that indicate it is unsuitable for repository development. A secondary purpose was to determine the status of knowledge in the major technical areas that affect the suitability of the site. This early site suitability evaluation (ESSE) was conducted by a team of technical personnel at the request of the Associate Director of the US Department of Energy (DOE) Office of Geologic Disposal, a unit within the DOE`s Office of Civilian Radioactive Waste Management. The Yucca Mountain site has been the subject of such evaluations for over a decade. In 1983, the site was evaluated as part of a screening process to identify potentially acceptable sites. The site was evaluated in greater detail and found suitable for site characterization as part of the Environmental Assessment (EA) (DOE, 1986) required by the Nuclear Waste Policy Act of 1982 (NWPA). Additional site data were compiled during the preparation of the Site Characterization Plan (SCP) (DOE, 1988a). This early site suitability evaluation has considered information that was used in preparing both-documents, along with recent information obtained since the EA and SCP were published. This body of information is referred to in this report as ``current information`` or ``available evidence.``

  5. Comparison of Prime Movers Suitable for USMC Expeditionary Power Sources

    This report documents the results of the ORNL investigation into prime movers that would be desirable for the construction of a power system suitable for the United States Marine Corps (USMC) expeditionary forces under Operational Maneuvers From The Sea (OMFTS) doctrine. Discrete power levels of {approx}1, 5, 15, and 30 kW are considered. The only requirement is that the prime mover consumes diesel fuel. A brief description is given for the prime movers to describe their basic scientific foundations and relative advantages and disadvantages. A list of key attributes developed by ORNL has been weighted by the USMC to indicate the level of importance. A total of 14 different prime movers were scored by ORNL personnel in four size ranges (1,5, 15, & 30 kW) for their relative strength in each attribute area. The resulting weighted analysis was used to indicate which prime movers are likely to be suitable for USMC needs. No single engine or prime mover emerged as the clear-cut favorite but several engines scored as well or better than the diesel engine. At the higher load levels (15 & 30 kW), the results indicate that the open Brayton (gas turbine) is a relatively mature technology and likely a suitable choice to meet USMC needs. At the lower power levels, the situation is more difficult and the market alone is not likely to provide an optimum solution in the time frame desired (2010). Several prime movers should be considered for future developments and may be satisfactory; specifically, the Atkinson cycle, the open Brayton cycle (gas turbine), the 2-stroke diesel. The rotary diesel and the solid oxide fuel cell should be backup candidates. Of all these prime movers, the Atkinson cycle may well be the most suitable for this application but is an immature technology. Additional demonstrations of this engine will be conducted at ORNL. If this analysis is positive, then the performance of a generator set using this engine, the open Brayton and the 2-stroke diesel should

    Reference genes are commonly used as a reliable approach to normalize the results of quantitative polymerase chain reaction (qPCR), and to reduce errors in the relative quantification of gene expression. Suitable reference genes belonging to numerous functional classes have been identified for various types of species and tissue. However, little is currently known regarding the most suitable reference genes for bone, specifically for the sheep mandibular condyle. Sheep are important for the study of human bone diseases, particularly for temporomandibular diseases. The present study aimed to identify a set of reference genes suitable for the normalization of qPCR data from the mandibular condyle of sheep. A total of 12 reference genes belonging to various functional classes were selected, and the expression stability of the reference genes was determined in both the normal and fractured area of the sheep mandibular condyle. RefFinder, which integrates the following currently available computational algorithms: geNorm, NormFinder, BestKeeper, and the comparative ΔCt method, was used to compare and rank the candidate reference genes. The results obtained from the four methods demonstrated a similar trend: RPL19, ACTB, and PGK1 were the most stably expressed reference genes in the sheep mandibular condyle. As determined by RefFinder comprehensive analysis, the results of the present study suggested that RPL19 is the most suitable reference gene for studies associated with the sheep mandibular condyle.

    Degraded forest of North Korea (DPRK; The Democratic People's Republic of Koprea) is not only confined itself, it could cause serious problem in Korean Peninsula. The importance of restoration for degraded land has increased to improve an healthy ecosystem and solve a shortage of food in North Korea lately. On the other hand, although effort of North Korea government, degraded problem have consistently got worse. There are two main reasons it does not show effectively. The most critical one is absence of technique and information to restore, they concentrate urgent problem which is related to a poor food supply. The other problem is that they demand an efficiency plan in a short period. In these aspect, this study aims selecting suitable tree by spatial characteristics and establishing phased restoration plan to support policy decision about a degraded land in North Korea. The suitable tree for restoration is taken from references which involve natural plant distribution of North and South Korea (ROK; Republic of Korea). Optimal environmental predicted map is deducted from accumulated data of plant physiology whose endemic environmental optimal range individually. It is integrated a map by order of priorities that first is suitable tree species according to the region, and second is clustering distribution rate in a same species. The two types of priority is applied to weighting method. The research result shows that 23 afforestation species fit to restore, and lager distributed plants agree with the major species in Korean Peninsula. The integrated map considers weight of priorities, and it appears that Picea jezoensis is matched the widest. The integrated map shows a view of suitable restoration according to the space, but this is finespun to utilize in a policy. Therefore It provides 3 step plan to support policy decision by Block Statistics, as 12.5km (long-term general plan), 5km (medium-term detailed plan), 1km (short-term implementation plan).

    The obstacles to bringing about consumer response to environmental dangers are particularly challenging for global problems like ozone depletion and the greenhouse effect. In this situation, there is the danger of what is commonly termed the tragedy of the commons, the ecological destruction that can occur from uncontrolled use of shared resources like the atmosphere. There is probably no country for which reductions in global warming provide an adequate economic incentive to reduce greenhouse gas emissions unilaterally, even though such action could yield substantial global benefits. From any one country's viewpoint, the costs of controlling emissions may exceed the benefits since, without international agreement, reductions achieved by one nation may be offset by another. Therefore, even though the entire world may be better off as a result of efforts to lower emissions, new economic incentives are necessary to lead the market to a socially efficient outcome. This paper describes the range of domestic and international policies that could be adopted to reduce emissions of greenhouse gases, and also discusses the results of modeling analyses of government actions that could reduce or increase such emissions

    With the increased interest in competitive market forces and growing recognition of the deficiencies in current practices, FERC and others are exploring alternatives to embedded cost pricing. A number of these alternatives are discussed in this chapter. Marketplace pricing, discussed briefly here, is the subject of the next chapter. Obviously, the pricing formula may combine several of these methodologies. One utility of which the authors are aware is seeking a price equal to the sum of embedded costs, opportunity costs, line losses, value of service, FERC's percentage adder formula and a contract service charge

    Certifications of trace elements in existing CRMs, especially biological CRMs, are far from satisfactory. Neutron activation analysis (NAA) for its inherent advantages combined with newly established parametric standardization, may contribute to improve this situation. The continuing progress of the hybrid extended k 0 -relative NAA technique developed in our laboratory is discussed. Examples are given to show the reliability of the method in certification of multielements. RNAA is still one of the best methods, or even the method of choice, in analysis at sub-μg/g concentration levels. The suitability of the technique for this purpose has been studied through the determination of rare earth elements at ng/g concentration level in two Chinese biological CRMs using both RNAA and ICPMS. Sampling behaviors of multielements in CRMs have been studied by INAA in an effort to develop CRMs suitable for analysis with small sample sizes. (author)

    Approximately 3% to 3.5% of the US population donates whole blood each year. Physicians might be approached by a blood donor because of a donor suitability issue, a positive postdonation test, or a donation-related complication. Approximately 83% of blood donors successfully donate; but 13% are rejected because of a donor suitability issue; 1% have a positive test, which is often nonspecific or false-positive; and 2% to 4% of the phlebotomies are not successful. The most common adverse physical events based on donor interviews are bruise (23%), sore arm (10%), fatigue (8%), and vasovagal reaction (7%), while uncommon events include nerve irritation (0.9%), syncope (0.1-0.3%), and arterial puncture (0.01%). One in 3400 donors (0.033%) report seeking outside medical care. Serious injuries occur but are very rare. More often, blood donors do well and feel satisfied with the blood donation experience.

    One of the habitat-based methodologies for impact assessment currently in use by the U.S. Fish and Wildlife Service is the Habitat Evaluation Procedures (HEP) (U.S. Fish and Wildlife Service 1980). HEP is based on the assumption that the quality of an area as wildlife habitat at a specified target year can be described by a single number, called a Habitat Suitability Index (HSI). An HSI of 1.0 represents optimum habitat: an HSI of 0.0 represents unsuitable habitat. The verbal or mathematical rules by which an HSI is assigned to an area are called an HSI model. A series of Habitat Suitability Index (HSI) models, described by Schamberger et al. (1982), have been published to assist users in applying HEP. HSI model building approaches are described in U.S. Fish and Wildlife Service (1981). One type of HSI model described in detail requires the development of Suitability Index (SI) graphs for habitat variables believed to be important for the growth, survival, standing crop, or other measure of well-being for a species. Suitability indices range from 0 to 1.0, with 1.0 representing optimum conditions for the variable. When HSI models based on suitability indices are used, habitat variable values are measured, or estimated, and converted to SI's through the use of a Suitability Index graph for each variable. Individual SI's are aggregated into an HSI. Standard methods for testing this type of HSI model did not exist at the time the studies reported in this document were performed. A workshop was held in Fort Collins, Colorado, February 14-15, 1983, that brought together biologists experienced in the use, development, and testing of aquatic HSI models, in an effort to address the following objectives: (1) review the needs of HSI model users; (2) discuss and document the results of aquatic HSI model tests; and (3) provide recommendations for the future development, testing, modification, and use of HSI models.

    Since 1974 Oak Ridge National Laboratory (ORNL) has been engaged in developing an automated procedure for land use suitability screening. The Nuclear Regulatory Commission has funded the project to aid in the selection of power plant sites in Maryland. Its purpose is to identify candidate areas from which specific candidate sites can be chosen for detailed analyses. The ORNL approach assures that certain key variables are examined empirically for every cell in the study region before candidate sites are selected. Each variable is assigned an importance weight and compatibility score based upon its effect on the economic, social, or ecologic costs associated with construction in a given cell. The weighted scores for each variable are aggregated and output as a suitability score for each cell

    The ability to reliably predict the end quality of software under development presents a significant advantage for a development team. It provides an opportunity to address high risk components earlier in the development life cycle, when their impact is minimized. This research proposes a model that captures the evolution of the quality of a software product, and provides reliable forecasts of the end quality of the software being developed in terms of product suitability. Development team skill, software process maturity, and software problem complexity are hypothesized as driving factors of software product quality. The cause-effect relationships between these factors and the elements of software suitability are modeled using Bayesian Belief Networks, a machine learning method. This research presents a Bayesian Network for software quality, and the techniques used to quantify the factors that influence and represent software quality. The developed model is found to be effective in predicting the end product quality of small-scale software development efforts.

    Irradiated foods can be detected by thermoluminescence (TL) of contaminating minerals. Altogether about 300 lots of herbs, spices, berries, mushrooms and seafood were studied by the TL method. Irradiated herbs and spices were easily differentiated from unirradiated ones two years after irradiation of a 10 kGy dose. The mineral composition of seafood was variable; and while calcite was suitable for the TL analysis, aragonite and smectite gave unreliable results. Control analyses during two years confirmed the reliability of TL method. (author)
