    On 27 March 2013, the European Commission published its first Renewable Energy Progress Report under the framework of the 2009 Renewable Energy Directive. Since the adoption of this directive and the introduction of legally binding renewable energy targets, most Member States experienced significant growth in renewable energy consumption. 2010 figures indicate that the EU as a whole is on its trajectory towards the 2020 targets with a renewable energy share of 12.7%. Moreover, in 2010 the majority of Member States already reached their 2011/2012 interim targets set in the Directive. However, as the trajectory grows steeper towards the end, more efforts will still be needed from the Member States in order to reach the 2020 targets. With regard to the EU biofuels and bioliquids sustainability criteria, Member States' implementation of the biofuels scheme is considered too slow. In accordance with the reporting requirements set out in the 2009 Directive on Renewable Energy, every two years the European Commission publishes a Renewable Energy Progress Report. The report assesses Member States' progress in the promotion and use of renewable energy along the trajectory towards the 2020 renewable energy targets. The report also describes the overall renewable energy policy developments in each Member State and their compliance with the measures outlined in the Directive and the National Renewable Energy Action Plans. Moreover, in accordance with the Directive, it reports on the sustainability of biofuels and bioliquids consumed in the EU and the impacts of this consumption. A consortium led by Ecofys was contracted by the European Commission to perform support activities concerning the assessment of progress in renewable energy and sustainability of biofuels.

    We have been working mainly on five inter-related subprojects: (1) derivation of the intermediate range nucleon-nucleon interaction with the new dramatically altered ππ s-wave interaction and using a new method that utilizes much shorter and simpler analytic continuation through the unphysical region that lies between the πN and ππ physical regions of the N anti N→ππ amplitude (with significantly improved accuracy for the nucleon-nucleon interaction); (2) construction of a short range phenomenological potential that, with the theoretical part mentioned above, gives a precise fit to the nucleon-nucleon data and is parameterized for easy use in nucleon calculations; (3) phase shift analyses of the world data below 400 MeV, especially the large amount of very precise data below 20 MeV and the new data near 55 MeV that have never been analyzed properly, and determining which phrases are given by theory at which energies; (4) the introduction of our K-matrix formulation of the Optimal Polynomial Expansion in order to accelerate convergence of the partial wave series at LAMPF energies; and (5) setting up of a cooperatively evaluated and verified permanent nucleon-nucleon data bank in the 0-1200 range that can be used by all nucleon-nucleon researchers (or anyone else) via Telenet dial-in and by means of a published compendium.

    Over the past 18 years a large inventory of glasses which have undergone leach testing has been built up at the Vitreous State Laboratory of The Catholic University of America. These glasses include a very wide range of compositions, most from actual mixed wastes and many natural analogs. A variety in the test protocol have been used, including PCT, ANSI, TCLP, IAEA, Flow, Soxhlet, MCC1, MCC3, and DIN. Many of these tests have been conducted for over a decade and are still ongoing. The progress of the tests is monitored by periodic sampling with fluid replacement. Twenty different leachants (including groundwaters, humic acid and pH buffers) have been employed. Occasionally, some of the glass is removed from the leaching vessels to observe the altered layers forming on the glass and to identify reaction products. Slight variations in the composition of the glass, subjected to PCT leaching, exhibit widely differing leaching behaviors. The evolution of leachate composition over time often shows a basically stable leach rate followed by a dramatic increase, with times of onset varying considerably, primarily as a function of glass composition. The same rapid rise in leachate has also been observe for a given glass composition studied at different S/V ratio. The study of such non-linearity in glass leaching is the subject of this review.

    In 2001, Australia introduced legislation requiring investment in new renewable electricity generating capacity. The legislation was significantly expanded in 2009 to give effect to a 20% Renewable Energy Target (RET). Importantly, the policy was introduced with bipartisan support and is consistent with global policy trends. In this article, we examine the history of the policy and establish that the ‘stop/start’ nature of renewable policy development has resulted in investors withholding new capital until greater certainty is provided. We utilise the methodology from Simshauser and Nelson (2012) to examine whether capital market efficiency losses would occur under certain policy scenarios. The results show that electricity costs would increase by between $51 million and $119 million if the large-scale RET is abandoned even after accounting for avoided renewable costs. Our conclusions are clear: we find that policymakers should be guided by a high level public policy principle in relation to large-scale renewable energy policy: constant review is not reform. -- Highlights: •We examine the history of Australian renewable energy policy. •We examine whether capital market efficiency losses occur under certain policy scenarios. •We find electricity prices increase by up to $119 million due to renewable policy uncertainty. •We conclude that constant review of policy is not reform and should be avoided

    Activin belongs to transforming growth factor (TGF)-β super family of growth and differentiation factors and activin pathway participated in broad range of cell process. Studies elaborated activin pathway maintain pluripotency in human stem cells and suggest that the function of activin/nodal signaling in self-renew would be conserved across embryonic and adult stem cells. In this study, we tried to determine the effect of activin signaling pathway in regulation of cancer stem cells as a potential target for cancer therapy in clinical trials. A population of colorectal cancer cells was selected by the treatment of activin A. This population of cell possessed stem cell character with sphere formation ability. We demonstrated activin pathway enhanced the colorectal cancer stem cells self-renew and contribute to colorectal cancer progression in vivo. Targeting activin pathway potentially provide effective strategy for colorectal cancer therapy. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Power quality improvement of low voltage grid is a great challenge that confronts the sophisticated power applications, because their performance is highly sensitive to the quality of power supply. Dynamic Voltage Restorer (DVR used widely as an efficient and skillful device to adjust electrical disturbances of the distribution grids. This paper introduces an overview of the components of the 3-phase dynamic voltage restorer and design its own control circuit. The performance of DVR was developed on the basis of the appropriate selection of Photovoltaic (PV module instead of the present conventional designs. Through this design, the need of series converter (DVR for the current from an electrical grid will end and the problems of power losses will curb. The PV-module is selected to meet the requirements of the DVR during voltage sag/swell on voltage line. The proposed system is mimicked in MATLAB software/Simulink and the findings are presented to prove the success of the design in terms of: Full congruence of the load voltage waveform with source voltage waveform, attaining 0.77% of THD analysis for the load voltage and the waveforms of PV system.

    Full Text Available The benefits of distributed generation (DG based on renewable energy sources leads to its high integration in the distribution network (DN. Despite its well-known benefits, mainly in improving the distribution system reliability and security, there are challenges encountered from a protection system perspective. Traditionally, the design and operation of the protection system are based on a unidirectional power flow in the distribution network. However, the integration of distributed generation causes multidirectional power flows in the system. Therefore, the existing protection systems require some improvement or modification to address this new feature. Various protection strategies for distribution system have been proposed so that the benefits of distributed generation can be fully utilized. This paper reviews the current progress in protection strategies to mitigate the impact of distributed generation in the distribution network. In general, the reviewed strategies in this paper are divided into: (1 conventional protection systems and (2 modifications of the protection systems. A comparative study is presented in terms of the respective benefits, shortcomings and implementation cost. Future directions for research in this area are also presented.

    The evolution of renewable energy over the past decade has surpassed all expectations. Global installed capacity and production from all renewable technologies have increased substantially, and supporting policies have continued to spread to more countries in all regions of the world. Developments in the early 2000's showed upward trends in global renewable energy investment, capacity, and integration across all sectors, yet most mainstream projections did not predict the extraordinary expansion of renewables that was to unfold over the decade ahead. Several factors set the foundation for this rapid growth. The various energy crises-beginning in the 1970's - and the subsequent economic downturns underscored the role of energy for both national and economic security. At the same time, a handful of pioneering countries-such as Germany, Denmark, Spain, and the United States-created critical markets for renewables, which drove early technological advances and economies of scale, setting the stage and helping to fuel the past decade of explosive market expansion. Growing emphasis on mitigating climate change and adapting to its impacts has further contributed to the momentum. Renewable energy's contribution to the global heat, power and transport sectors has increased steadily. While growth in renewable's share of total energy use has been moderated by increases in both population and world energy demand-most notably in developing and emerging economies-renewable energy markets and technology developments have accelerated quickly, even when compared to other rapidly developing technologies such as mobile phones. Although the last decade has seen tremendous advances in the electricity sector, the renewable heating and cooling sector has lagged behind. This is despite the marked growth since 2004 in the use of geothermal, solar thermal, and biomass heating technologies for water and space heating, process heat, and cooling. Given that the share of

    In Canada, the technology for disposal of uranium mine wastes and reclamation of mines has evolved over a period of 52 years. Early practice involved dumping untreated wastes into the nearest depression or lake and leaving rock and infrastructure in place. Now, the practice is to deposit chemically-stabilized tailings, waste rock and building rubble into highly engineered waste management facilities or mine openings. Similarly the ''footprint'' of the mining activity has been reduced to a very small area and the site is restored as-close-as-possible to pre-mining status. This paper describes the evolution of disposal and reclamation methods and the criteria which have determined the development path followed. Remediation techniques to bring older and now unacceptable tailings deposits into satisfactory compliance with current regulations are reviewed. Some monitoring results are presented. All of the uranium mines in Elliot Lake, Ontario, a large uranium producer since 1957, are now permanently closed. Considerable progress has been made on decommissioning the tailings areas by developing long term maintenance of water covers on some, and water treatment plants and stable soil covers on the others. The innovative methods being used to develop the water covers are described, along with the challenges remaining. Methods now under development in Saskatchewan for subaqueous deposition of paste tailings for permanent disposal in mined out open pits are also described. This method will provide for the first time, ''walkaway'', meaning no long term monitoring and maintenance will be required

    The Endangered Species Act (originally passed in 1973) is a Federal statute that protects both animal and plant species. The Endangered Species Act identifies species which are, without careful management, in danger of becoming extinct and species that are considered threatened. Along with the designation of threatened or endangered, the Endangered Species Act provides for the identification of appropriate habitat for these species. Since 1993, the United States Department of Energy`s (DOE) Environmental Restoration (ER) Program has supported a program to survey the Oak Ridge Reservation (ORR) for threatened and endangered species. The Environmentally Sensitive Areas Surveys Program initiated vascular plant surveys during fiscal year 1993 and vertebrate animal surveys during fiscal year 1994 to determine the baseline condition of threatened and endangered species on the ORR at the present time. Data collected during these surveys are currently aiding Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Remedial Investigations on the ORR. They also provide data for ER and Waste Management decision documents, ensure that decisions have technical and legal defensibility, provide a baseline for ensuring compliance with principal legal requirements and will increase public confidence in DOE`s adherence to all related environmental resources rules, laws, regulations, and instructions. This report discusses the progress to date of the threatened and endangered species surveys of the ORR.

  3. Conservation of coral reefs through active restoration measures: recent approaches and last decade progress.

    2005-06-15

    The scientific discipline of active restoration of denuded coral reef areas has drawn much attention in the past decade as it became evident that this ecosystem does not often recover naturally from anthropogenic stress without manipulation. Essentially, the choices are eitherthe continuous degradation of the reefs or active restoration to encourage reef development. As a result, worldwide restoration operations during the past decade have been recognized as being a major tool for reef rehabilitation. This situation has also stirred discussions and debates on the various restoration measures suggested as management options, supplementary to the traditional conservation acts. The present essay reviews past decade's (1994-2004) approaches and advances in coral reef restoration. While direct coral transplantation is still the primer vehicle of operations used, the concept of in situ and ex situ coral nurseries (the gardening concept), where coral materials (nubbins, branches, spats) are maricultured to a size suitable for transplantation, has been gaining recognition. The use of nubbins (down to the size of a single or few polyps) has been suggested and employed as a unique technique for mass production of coral colonies. Restoration of ship grounding sites and the use of artificial reefs have become common tools for specific restoration needs. Substrate stabilization, 3-D structural consideration of developing colonies, and the use of molecular/biochemical tools are part of novel technology approaches developed in the past decade. Economic considerations for reef restoration have become an important avenue for evaluating success of restoration activities. It has been suggested that landscape restoration and restoration genetics are important issues to be studied. In the future, as coral reef restoration may become the dominant conservation act, there would be the need not only to develop improved protocols but also to define the conceptual bases.

    During the restoration of degraded bogs and other peatlands, both habitat and functional recovery can be closely linked with nutrient cycling, which is reflected in pore- and surface-water chemistry. Several peatland restoration studies have shown that the time required for recovery of target conditions is slow (>10 years); for heavily-impacted, drained and afforested peatlands of northern Scotland, recovery time is unknown. We monitored pore- and surface-water chemistry across a chronosequence of formerly drained, afforested bog restoration sites spanning 0-17 years, using a space-for-time substitution, and compared them with open blanket bog control sites. Our aims were to measure rate of recovery towards bog conditions and to identify the best suite of water chemistry variables to indicate recovery. Our results show progress in recovery towards bog conditions over a 0-17 year period post-restoration. Elements scavenged by trees (Mg, Na, S) completely recovered within that period. Many water chemistry variables were affected by the restoration process itself, but recovered within 11 years, except ammonium (NH 4 + ), Zn and dissolved organic carbon (DOC) which remained elevated (when compared to control bogs) 17 years post restoration. Other variables did not completely recover (water table depth (WTD), pH), exhibiting what we term "legacy" effects of drainage and afforestation. Excess N and a lowered WTD are likely to slow the recovery of bog vegetation including key bog plants such as Sphagnum mosses. Over 17 years, we measured near-complete recovery in the chemistry of surface-water and deep pore-water but limited progress in shallow pore-water. Our results suggest that at least >17 years are required for complete recovery of water chemistry to bog conditions. However, we expect that newer restoration methods including conifer harvesting (stem plus brash) and the blocking of plough furrows (to increase the WTD) are likely to accelerate the restoration process

These humancaused, higher levels of CO{sub 2} may enhance the atmospheric greenhouse effect and may contribute to climate change. Many reclaimed coal-surface mine areas in the eastern U.S. are not in productive use. Reforestation of these lands could provide societal benefits, including sequestration of atmospheric carbon. The goal of this project was to determine the biological and economic feasibility of restoring high-quality forests on the tens of thousands of hectares of mined land and to measure carbon sequestration and wood production benefits that would be achieved from large-scale application of forest restoration procedures. We developed a mine soil quality model that can be used to estimate the suitability of selected mined sites for carbon sequestration projects. Across the mine soil quality gradient, we tested survival and growth performance of three species assemblages under three levels of silvicultural. Hardwood species survived well in WV and VA, and survived better than the other species used in OH, while white pine had the poorest survival of all species at all sites. Survival was particularly good for the site-specific hardwoods planted at each site. Weed control plus tillage may be the optimum treatment for hardwoods and white pine, as any increased growth resulting from fertilization may not offset the decreased survival that accompanied fertilization. Grassland to forest conversion costs may be a major contributor to the lack of reforestation of previously reclaimed mine lands in the Appalachian coal-mining region. Otherwise profitable forestry opportunities may be precluded by these conversion costs, which for many combinations of factors (site class, forest type, timber prices, regeneration intensity, and interest rate) result in negative land expectation values

    In May 2004, a team of experienced Australian specialists in the field of renewable energy technology conducted a Mission to the United States of America led by the Renewable and Sustainable Energy ROUNDTABLE. The Mission was made possible by a generous grant from the Department of Education Science and Training (DEST), administered through the Australian Academy of Technological Sciences and Engineering (ATSE) under the Innovation Access Programme. Mission participants engaged in a three day structured workshop with the US National Renewable Energy Laboratory (NREL), and the opportunity was taken to meet leading USA research teams and visit relevant facilities ranging from solar thermal and photovoltaic testing, wind through to bioenergy an biorefining. The Mission concluded in Washington DC with a series of meetings with the US Department of Energy, the World Bank and Austrade. The Mission was extremely successful in terms of relationship building, technical learning and the development of future commercial opportunities for Australian businesses. It was conducted within the context of the United States - Australia Climate Action Partnership (CAP). This paper provides an overview of the Mission, its objectives and key outcomes

  10. The progressive inefficiency of replacing renewable obligation certificates with contracts-for-differences in the UK electricity market

    International Nuclear Information System (INIS)

    Bunn, Derek; Yusupov, Tim

    2015-01-01

    This paper looks at the emerging risk/return profile for new renewable assets as a conventional wholesale electricity market progressively decarbonises. Using a detailed fundamental model of price formation risks, under increasing replacement of fossil fuel facilities with onshore and offshore wind, we show that the risk return profile becomes less attractive over time, and may therefore need sustained and possibly increasing policy support. Furthermore, we show that green certificate trading may become progressively more attractive as a supplementary support to wholesale prices, compared to fixed feed-in-tariffs. This is because the increasingly negative correlation between renewable output and wholesale prices reduces its revenue risk compared to fixed feed-in tariffs, if other factors remain constant, and thereby improves conventional financial performance risk metrics. In particular, this suggests that the recent energy policy change in Britain to move away from green certificates and into contracts-for-differences may have been ill-founded. -- Highlights: •The asset performance risk of wind investments deteriorates with greater wind penetration. •Green certificates may offer lower investment risk than feed-in tariffs. •Detailed fundamental modelling reveals subtle asset performance risks for wind. •Recent UK policy changes may be ill-founded

    Succinic acid is a four-carbon dicarboxylic acid, which has attracted much interest due to its abroad usage as a precursor of many industrially important chemicals in the food, chemicals, and pharmaceutical industries. Facing the shortage of crude oil supply and demand of sustainable development, biological production of succinic acid from renewable resources has become a topic of worldwide interest. In recent decades, robust producing strain selection, metabolic engineering of model strains, and process optimization for succinic acid production have been developed. This review provides an overview of succinic acid producers and cultivation technology, highlight some of the successful metabolic engineering approaches. Copyright © 2017 Elsevier Ltd.

    After more dm 35 years of operation, the uranium mining and milling activities in Hungary will be finally shut down by the end of 1997. The surveying programme on the affected area was started in 1991, and the first phase of the remediation project was launched in 1992-93. In the last few years a new concept and strategy has been prepared for the next phase of restoration tasks. The restoration will mainly follow the principle of application of step by step approach to the solution of each task. Due to lack of approved national regulations, authorization in the form of letters are obtained on specific issues of remedial action on a case by case basis. The radiological requirements for both reuse and restoration of the affected areas call for setting up radiation limits. The radiation monitoring and radiological characterization of the affected areas both during operation as well as after restoration are being systematically performed. The monitoring of water contamination is given high priority, because the uranium milling and milling sites have a lot of surface water and aquifers. So far, 3 mines have been shut down while 2 mines are still operating. After final close down the mines will be flooded, and the monitoring system will be expanded and upgraded. Major portion of waste rock piles have been restored, and a number of experiments and investigations have been performed for decreasing the contamination of heap leaching and for selection of cover layers of tailings ponds. As a prelude to decommissioning of milling facility preliminary survey of items and equipment for reuse or disposal has been started. (author)

  16. Progress and renewal in gustation: new insights into taste bud development.

    Science.gov (United States)

    Barlow, Linda A

    2015-11-01

    The sense of taste, or gustation, is mediated by taste buds, which are housed in specialized taste papillae found in a stereotyped pattern on the surface of the tongue. Each bud, regardless of its location, is a collection of ∼100 cells that belong to at least five different functional classes, which transduce sweet, bitter, salt, sour and umami (the taste of glutamate) signals. Taste receptor cells harbor functional similarities to neurons but, like epithelial cells, are rapidly and continuously renewed throughout adult life. Here, I review recent advances in our understanding of how the pattern of taste buds is established in embryos and discuss the cellular and molecular mechanisms governing taste cell turnover. I also highlight how these findings aid our understanding of how and why many cancer therapies result in taste dysfunction. © 2015. Published by The Company of Biologists Ltd.

  17. Feed-in tariffs versus quotas: how to promote renewable s and stimulate technical progress for cost decrease?

    International Nuclear Information System (INIS)

    2002-01-01

    Incentive schemes for the development of renewable energy sources may focus on quantities (defining national targets and setting up bidding systems, or quota systems providing for green certificate trading), or they may focus on prices (feed-in tariffs). Whatever the system chosen, the role of the public authorities is quite specific: to stimulate technical progress and speed up the technological learning processes so that ultimately renewable energy technologies will be able to compete with conventional technologies, once the environmental costs have been internalized. A comparison of instruments must thus take into account the characteristics of the innovation process and adoption conditions (uncertainties regarding cost curves, learning effects) which means also looking at dynamic efficiency criteria. The paper concludes that a system of feed-in tariffs is more efficient than a bidding system, but highlights the theoretical interest of green certificate trading which must be confirmed through practice, given the influence of market structures and rules on the performance of this type of approach.

  18. Environmental restoration in regions of uranium mining and milling in Ukraine: Progress, problems and perspectives

    International Nuclear Information System (INIS)

    Rudy, C.

    1997-01-01

    Uranium exploration activities in Ukraine were initiated in 1946. So far 21 uranium reserves have been identified in the Southern regions of Ukraine. Industrial scale mining has been undertaken in two main areas -ZhovtiVody (Dnipropetrovsk region) and more recently - near the city of Kirovograd. Uranium milling capabilities were created in ZhovtiVody and Dniprodzerzhinsk. At Dniprodzerzhinsk Prydniprovsky Chemical Plant uranium milling started in the late 40's, initially using ores from the countries of Central Europe. Lack of relevant environmental standards and appropriate technologies for uranium extraction contributed to contamination of both industrial and residential areas. As a result, about 1340 ha of industrial areas were contaminated and ecologically affected. Extensive utilization of waste rock pile for road and building construction in the 50's and 60's resulted in contamination of residential areas in the region. To provide a comprehensive solution to the radioecological problems of the ZhovtiVody area a State Programme of Actions up to the year 2005 was adopted by the Ukrainian government in 1995. A timely methodological and information support for national activities on environmental restoration in Ukraine was provided by IAEA regional project RER/9/022. In April 1996 under the framework of the RER/9/022 project, seminar on environmental restoration in regions of uranium mining and milling took place in the town of Zhovti Vody, that allowed involvement of local experts and organizations into the project activities directly. The proposed paper is based on the vast amount of data accumulated in Ukraine during RER/9/022 covering the period 1993-1996. Severe lack of finance adversely affected all activities within the nuclear sector, environmental restoration implementation being the most affected. In such circumstances RER/9/022 remained as one of the most valuable contributing factors in the development of regulations, guidance and practices in the

    The worldwide unrestrained emission of carbon dioxide (CO 2 ) has caused serious environmental pollution and climate change issues. For the sustainable development of human civilization, it is very desirable to convert CO 2 to renewable fuels through clean and economical chemical processes. Recently, electrocatalytic CO 2 conversion is regarded as a prospective pathway for the recycling of carbon resource and the generation of sustainable fuels. In this review, recent research advances in electrocatalytic CO 2 reduction are summarized from both experimental and theoretical aspects. The referred electrocatalysts are divided into different classes, including metal-organic complexes, metals, metal alloys, inorganic metal compounds and carbon-based metal-free nanomaterials. Moreover, the selective formation processes of different reductive products, such as formic acid/formate (HCOOH/HCOO - ), monoxide carbon (CO), formaldehyde (HCHO), methane (CH 4 ), ethylene (C 2 H 4 ), methanol (CH 3 OH), ethanol (CH 3 CH 2 OH), etc. are introduced in detail, respectively. Owing to the limited energy efficiency, unmanageable selectivity, low stability, and indeterminate mechanisms of electrocatalytic CO 2 reduction, there are still many tough challenges need to be addressed. In view of this, the current research trends to overcome these obstacles in CO 2 electroreduction field are summarized. We expect that this review will provide new insights into the further technique development and practical applications of CO 2 electroreduction.

    This renewal proposal requests continued funding for our program in experimental medium-energy nuclear physics. The focus of our program remains the understanding of the short-range part of the strong interaction in the nuclear medium. In the past three years we have focused our attention ever more sharply on experiments with real tagged photons at CEBAF. We are part of the Hall-B Collaboration at CEBAF. We are co-spokespersons on two approved CEBAF experiments, Photoreactions on 3 He and Photoabsorption and Photofission of Nuclei, and we are preparing another, Nondiffractive Photoproduction of the ρ Meson with Linearly Polarized Photons, for presentation to the next CEBAF PAC. We are part of the team that is instrumenting the Photon Tagger and a high-energy tagged polarized-photon beam for Hall B; some of the instrumentation for these projects is being built at our Nuclear Detector Laboratory, under the auspices of The George Washington University Center for Nuclear Studies. Our recent measurements of pion scattering from 3 H and 3 He at LAMPF and of cluster knockout from few-body nuclei at NIKHEF have yielded very provocative results, showing the importance of the very light nuclei as a laboratory for quantifying important aspects of the nuclear many-body force. We look forward to expanding our studies of short-range forces in nuclei, particularly the very fight nuclei using electromagnetic probes and employing the extraordinary power of CEBAF and the CLAS

    Wind energy has been the promising energy technology since 1980s in terms of percentage of yearly growth of installed capacity. However the progress of wind energy has not been evenly distributed around the world. Particularly, in South East Asian countries like Malaysia and Singapore, though the Governments are keen on promoting wind energy technology, it is not well practiced due to the low wind speeds. Owing to the recent advancements in wind turbine designs, even Malaysia is well suited for wind energy by proper choice of wind turbines. As evidence, this paper presents successful wind turbines with simulated study outcomes to encourage wind power developments in Malaysia.

    Five patients underwent preoperative embolization of osseous metastases from renal cell carcinoma. The group consisted of four men and one woman who ranged in age from 46 to 79 years. The lesions were located in the pubic ramus and acetabulum, proximal femur, femoral midshaft, proximal humerus, and proximal tibia. All embolizations were performed within 24 hours of surgery. The internal fixation and tumor curettage was accomplished with estimated perioperative blood loss ranging from 10 ml to 1,250 ml. All patients had significant restoration of function following surgery. The authors suggest that preoperative embolization is an important and efficacious adjunct in the management of hypervascular renal cell osseous metastases

    Uranium ores have been mined in Bohemian Massif in different mining districts i.e. in West Bohemia, Pribram region and Middle Bohemia, Rozna district and in Straz pod Ralskem district. The latter is represented by stratiform sandstone type of deposit where acid in-situ leaching has been applied as mining method since 1968. More than 4 million tons of leaching acids have been injected into the ore bearing sandstones. The district falls in an area of natural water protection in North Bohemian Cretaceous platform. A complex evaluation of negative impact of uranium mining and milling in this area has been clearly articulated in Government Decrees Nos.:366/92, 429/93, 244/95 and 170/96. A special declining regime of mining has been ordered for the implementation of which together with the Government Commission of Experts a remediation programme has been designed and put into operation in 1996. The uranium producer DIAMO a.s. prepared a Concept of Restoration of the area affected by in-situ leaching and MEGA a.s. has prepared the Environmental Impact Assessment (E.I.A.) according to the law No.244/1992. The Ministry of the Environment issued an Environmental Impact Statement which included evaluation of the condition of mining and restoration programme because both activities will influence the environment of the district.

    The overall purpose of this project is to evaluate the biological and economic feasibility of restoring high-quality forests on mined land, and to measure carbon sequestration and wood production benefits that would be achieved from forest restoration procedures. In this quarterly report, we present a preliminary comparison of the carbon sequestration benefits for two forest types used to convert abandoned grasslands for carbon sequestration. Annual mixed hardwood benefits, based on total stand carbon volume present at the end of a given year, range from a minimum of $0/ton of carbon to a maximum of $5.26/ton of carbon (low prices). White pine benefits based on carbon volume range from a minimum of $0/ton of carbon to a maximum of $18.61/ton of carbon (high prices). The higher maximum white pine carbon payment can primarily be attributed to the fact that the shorter rotation means that payments for white pine carbon are being made on far less cumulative carbon tonnage than for that of the long-rotation hardwoods. Therefore, the payment per ton of white pine carbon needs to be higher than that of the hardwoods in order to render the conversion to white pine profitable by the end of a rotation. These carbon payments may seem appealingly low to the incentive provider. However, payments (not discounted) made over a full rotation may add up to approximately $17,493/ha for white pine (30-year rotation), and $18,820/ha for mixed hardwoods (60-year rotation). The literature suggests a range of carbon sequestration costs, from $0/ton of carbon to $120/ton of carbon, although the majority of studies suggest a cost below $50/ ton of carbon, with van Kooten et al. (2000) suggesting a cutoff cost of $20/ton of carbon sequestered. Thus, the ranges of carbon payments estimated for this study fall well within the ranges of carbon sequestration costs estimated in previous studies.

    The overall purpose of this project is to evaluate the biological and economic feasibility of restoring high-quality forests on mined land, and to measure carbon sequestration and wood production benefits that would be achieved from forest restoration procedures. We are currently estimating the acreage of lands in VA, WV, KY, OH, and PA mined under SMCRA and reclaimed to non-forested post-mining land uses that are not currently under active management, and therefore can be considered as available for carbon sequestration. To determine actual sequestration under different forest management scenarios, a field study was installed as a 3 x 3 factorial in a random complete block design with three replications at each of three locations, Ohio, West Virginia, and Virginia. The treatments included three forest types (white pine, hybrid poplar, mixed hardwood) and three silvicultural regimes (competition control, competition control plus tillage, competition control plus tillage plus fertilization). Each individual treatment plot is 0.5 acres. Each block of nine plots requires 4.5 acres, and the complete installation at each site requires 13.5 acres. The plots at all three locations have been installed and the plot corners marked with PVC stakes. GPS coordinates of each plot have been collected. Soil samples were collected from each plot to characterize the sites prior to treatment. Baseline soil carbon was determined for each of the eighty-one plots. Fertility analysis of soil samples was completed and these data were used to prepare fertilizer prescriptions and the pre-designated plots were fertilized. We also evaluated economic-based policy instruments that are designed to mitigate the reforestation burden borne by the owner of reclaimed mined land. Results suggest that although profitability of reforestation of these previously reclaimed mine lands may be achievable on better sites under lower interest rates, substantial payments would be required to reach &apos

    The overall purpose of this project is to evaluate the biological and economic feasibility of restoring high-quality forests on mined land, and to measure carbon sequestration and wood production benefits that would be achieved from forest restoration procedures. In this quarterly report we present data that show the spatial distribution of carbon in mine soils. Soil carbon data from deep soil pits from grassland minelands located in Ohio, Virginia, and West Virginia were analyzed to determine the vertical distribution and variability of soil organic carbon (SOC) down to a 2-m depth. Regression analyses were used to describe and model the distribution by soil depth of C(wt%), BD{sub fines}(g cm{sup -3}), and fines (vol%) in mine soils. The volume of excavated mine soil samples was transformed in terms of costs of digging and sampling, including sample collection and preparation, and C(wt%) analysis, in order to determine the maximum cost-effective depth (MCD) for carbon inventorying on the mined sites analyzed. Based on the horizontal variation of SOC(g m{sup -2}), we determined the sampling intensity required to achieve a desired accuracy of the amount of sequestered SOC(g m{sup -2}) at certain probability levels. The MCD and sampling intensity measurements were used to determine the minimum detectable difference (MDD) of SOC(g m{sup -2}) between two consecutive carbon inventories. We also proposed a method to determine the minimum number of years before a future C inventory event is carried out so that the measured SOC(g m{sup -2}) differences were greater than MDD. We used geostatistical analyses procedures to determine spatial dependence predictability of surface SOC(g m{sup -2}) data on the minelands analyzed. Kriging techniques were used to create surface SOC(g m{sup -2}) maps for the sites in Ohio and West Virginia. The average C sequestration rate in the surface soil layer for the Ohio (age 9) sites was estimated at 124 g C m{sup -2} yr{sup -1}, and it was

During the reporting period we compiled and evaluated all soil properties measured on the study sites. Statistical analysis of the properties was conducted, and first year survival and growth of white pine, hybrid poplars, and native hardwoods was assessed. Hardwood species survived better at all sites than white pine or hybrid poplar. Hardwood survival across treatments was 80%, 85%, and 50% for sites in Virginia, West Virginia, and Ohio, respectively, while white pine survival was 27%, 41%, and 58%, and hybrid poplar survival was 37%, 41%, and 72% for the same sites, respectively. Hybrid poplar height and diameter growth were superior to those of the other species tested, with the height growth of this species reaching 126.6cm after one year in the most intensive treatment at the site in Virginia.

    The work of the Stony Brook Nuclear Theory Group covers a broad range of topics in theoretical nuclear structure. Primary emphasis is placed on understanding the origin of the nucleon-nucleon and meson-nucleon interactions. Phenomenological treatments of QCD, using chiral invariance as a guide, are central to our efforts here; through the chiral bag model they give us also an improved understanding of the structure of hadrons. Starting from the free interaction, many-body techniques have been used to construct the effective interaction between nucleons in nuclei. Analysis of a wide range of nuclear phenomena has been carried out using such effective interactions. Among the most interesting are nuclear giant resonances for which we offer a dynamical theory of nuclear vibrations which emphasizes the energy dependence of the effective interaction. Continuing our earlier description of the collapse of large stars, we have worked out the formation of the shock wave upon bounce, and its progress out through the star. We believe this shock wave to blow off the mantle and envelope of the star, leaving a compact remnant, the pulsar. Computer calculations follow this scenario until the shock is some distance beyond the neutrino sphere, where the shock then runs out of energy. We are extending these calculations to a description of explosive nucleosynthesis. We have also been studying heavy ion reactions. In the low-energy regime, we have concentrated on nuclear quasimolecular states, and on the angular dependence of deep inelastic scattering. In the relativistic regime, we wish to extend our old work on states of dense matter

    Pharmacotherapy is effective in helping many patients suffering from psychiatric and neurological disorders, and both psychotherapeutic and stimulation-based techniques likewise have important roles to play in their treatment. However, therapeutic progress has recently been slow. Future success for improving the control and prevention of brain disorders will depend upon deeper insights into their causes and pathophysiological substrates. It will also necessitate new and more rigorous methods for identifying, validating, developing and clinically deploying new treatments. A field of Research and Development (R and D) that remains critical to this endeavour is Neuropsychopharmacology which transformed the lives of patients by introducing pharmacological treatments for psychiatric disorder some 60 years ago. For about half of this time, the European College of Neuropsychopharmacology (ECNP) has fostered efforts to enhance our understanding of the brain, and to improve the management of psychiatric disorders. Further, together with partners in academia and industry, and in discussions with regulators and patients, the ECNP is implicated in new initiatives to achieve this goal. This is then an opportune moment to survey the field, to analyse what we have learned from the achievements and failures of the past, and to identify major challenges for the future. It is also important to highlight strategies that are being put in place in the quest for more effective treatment of brain disorders: from experimental research and drug discovery to clinical development and collaborative ventures for reinforcing "R and D". The present article sets the scene, then introduces and interlinks the eight articles that comprise this Special Volume of European Neuropsychopharmacology. A broad-based suite of themes is covered embracing: the past, present and future of "R and D" for psychiatric disorders; complementary contributions of genetics and epigenetics; efforts to improve the

    We previously reported frequent loss of microRNA‑218 (miR‑218) in human cervical cancer, which was associated with tumor progression and poor prognosis. In this study, we investigated whether restoration of the miR‑218 level is a valid strategy for the treatment of cervical cancer. The expression of miR‑218 in cervical cancer samples and cell lines was quantified by reverse transcription TaqMan quantitative (RT‑q)PCR. Overexpression of miR‑218 was achieved by both transient and stable transfection, using a miR‑218 mimic and a miR‑218‑expressing plasmid, respectively. Alterations in cellular proliferation and cell‑cycle progression were measured by the MTT assay and flow cytometry analysis. Nude mice bearing SiHa xenografts were used to investigate the functions of miR‑218 and carboplatin on tumor growth and weight. The expression of cycle‑related proteins was detected by western blotting and immunohistochemical staining. In vitro, miR‑218 significantly inhibited cellular growth in all four cell lines tested (P=0.021 for CaSki, P=0.009 for HeLa, P=0.016 for SiHa, and P=0.029 for C33A). Overexpression of miR‑218 induced G1 phase arrest and reduced expression of cyclin D1 and CDK4. In vivo, restoration of miR‑218 notably inhibited tumor growth and decreased tumor weight. In primary cultured samples, tumors with high levels of miR‑218 were more sensitive to carboplatin (R2=0.3319, P=0.0026); consistently, miR‑218 overexpression suppressed tumor growth, induced cell‑cycle arrest, and reduced the cyclin D1 level. Based on these and previous results, we conclude that restoration of the miR‑218 level inhibits the growth of cervical cancer cells both in vitro and in vivo; furthermore, overexpression of miR‑218 sensitizes cervical cancer cells to carboplatin. Our findings suggest a novel therapy for cervical cancer based on miR‑218, especially in patients with reduced levels of miR‑218.

    The overall purpose of this project is to evaluate the biological and economic feasibility of restoring high-quality forests on mined land, and to measure carbon sequestration and wood production benefits that would be achieved from forest restoration procedures. We are currently estimating the acreage of lands in Virginia, West Virginia, Kentucky, Ohio, and Pennsylvania mined under SMCRA and reclaimed to non-forested post-mining land uses that are not currently under active management, and therefore can be considered as available for carbon sequestration. To determine actual sequestration under different forest management scenarios, a field study was installed as a 3 x 3 factorial in a random complete block design with three replications at each of three locations, one each in Ohio, West Virginia, and Virginia. The treatments included three forest types (white pine, hybrid poplar, mixed hardwood) and three silvicultural regimes (competition control, competition control plus tillage, competition control plus tillage plus fertilization). Each individual treatment plot is 0.5 acres. Each block of nine plots is 4.5 acres, and the complete installation at each site is 13.5 acres. During the reporting period we determined that by grinding the soil samples to a finer particle size of less than 250 μm (sieve No. 60), the effect of mine soil coal particle size on the extent to which these particles will be oxidized during the thermal treatment of the carbon partitioning procedure will be eliminated, thus making the procedure more accurate and precise. In the second phase of the carbon sequestration project, we focused our attention on determining the sample size required for carbon accounting on grassland mined fields in order to achieve a desired accuracy and precision of the final soil organic carbon (SOC) estimate. A mine land site quality classification scheme was developed and some field-testing of the methods of implementation was completed. The classification model

    'The purpose of this project is to develop a computer code for joint inversion of seismic and electrical data, to improve underground imaging for site characterization and remediation monitoring. The computer code developed in this project will invert geophysical data to obtain direct estimates of porosity and saturation underground, rather than inverting for seismic velocity and electrical resistivity or other geophysical properties. This is intended to be a significant improvement in the state-of-the-art of underground imaging, since interpretation of data collected at a contaminated site would become much less subjective. Potential users include DOE scientists and engineers responsible for characterizing contaminated sites and monitoring remediation of contaminated sites. In this three-year project, the authors use a multi-phase approach consisting of theoretical and numerical code development, laboratory investigations, testing on available laboratory and borehole geophysics data sets, and a controlled field experiment, to develop practical tools for joint electrical and seismic data interpretation. This report summarizes work after about 1.7 years of a 3-year project. Progress on laboratory measurements is described first, followed by progress on developing algorithms for the inversion code to relate geophysical data to porosity and saturation.'

    The case is of a mid-40s patient who developed progressive muscle weakness and loss of mobility over 6 weeks due to primary progressive multiple sclerosis. 2.5 days before admission, she became bed bound with weakness of 1/5 on the Oxford scale. She normally rested for a couple of days after similar periods of worsening symptoms and then got back on her feet although with worse balance. She was treated with optokinetic chart stimulation and sensory interaction for balance (OKCSIB) protocol. Within 2 days of intervention, she was mobile with a delta frame and supervision of one. By the end of a week, she was independently mobile with her delta frame. It is recommended that instead of just practising function, the OKCSIB protocol be used to regain antigravity extensor control loss of which leads to deteriorating function in neurological conditions. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    This report gives a brief status and description of new developments in the remediation activities which are going on at Zirovski Vrh Uranium Mine site during the last two years. The progress of the implementation has slowed down compared to the plans. Reasons for that are: (a) legal problems (responsibilities between two authorized governmental agencies) in the procedure for obtaining location permit for the long-term site remediation of the wide exploitation area, particularly for the mill tailings disposal site; (b) lack of funding. However, some tasks have been performed during this period in the field of investigations, reporting to the authorities, design and to a lesser extent actual implementation. The investigations have concentrated on the hydrology of the site underground waters, radiological site characterization and investigation of locally available materials for constructing the cover of the waste disposal sites. On the basis of R2Vs Environmental Impact Report, Slovenian Health Inspectorate has officially set authorized limits for radioactive pollutants emission for mine water and mill tailings and mine waste disposal sites. Detailed drawings of the mill site decommissioning have been presented to the authorities. Approval by the authorities is expected to be granted soon. This represents the last stage in the procedures for obtaining permissions before the field work at the mill site can be formally started. The problem of the mill tailings earth slide has been successfully solved by constructing geotechnical underground water drainage structures including vertical dewatering wells. Some research and investigation projects are in progress to promote knowledge on radiological site characterization, water pathway emission of the pollutants and to identify required materials locally available for the mine waste and the mill tailings cover construction.

    2009-03-31

    The goal of this project is to provide temporary upstream passage of bull trout around Albeni Falls Dam on the Pend Oreille River, Idaho. Our specific objectives are to capture fish downstream of Albeni Falls Dam, tag them with combination acoustic and radio transmitters, release them upstream of Albeni Falls Dam, and determine if genetic information on tagged fish can be used to accurately establish where fish are located during the spawning season. In 2007, radio receiving stations were installed at several locations throughout the Pend Oreille River watershed to detect movements of adult bull trout; however, no bull trout were tagged during that year. In 2008, four bull trout were captured downstream of Albeni Falls Dam, implanted with transmitters, and released upstream of the dam at Priest River, Idaho. The most-likely natal tributaries of bull trout assigned using genetic analyses were Grouse Creek (N = 2); a tributary of the Pack River, Lightning Creek (N = 1); and Rattle Creek (N = 1), a tributary of Lightning Creek. All four bull trout migrated upstream from the release site in Priest River, Idaho, were detected at monitoring stations near Dover, Idaho, and were presumed to reside in Lake Pend Oreille from spring until fall 2008. The transmitter of one bull trout with a genetic assignment to Grouse Creek was found in Grouse Creek in October 2008; however, the fish was not found. The bull trout assigned to Rattle Creek was detected in the Clark Fork River downstream from Cabinet Gorge Dam (approximately 13 km from the mouth of Lightning Creek) in September but was not detected entering Lightning Creek. The remaining two bull trout were not detected in 2008 after detection at the Dover receiving stations. This report details the progress by work element in the 2008 statement of work, including data analyses of fish movements, and expands on the information reported in the quarterly Pisces status reports.

  3. The B-MYB transcriptional network guides cell cycle progression and fate decisions to sustain self-renewal and the identity of pluripotent stem cells.

    Embryonic stem cells (ESCs) are pluripotent and have unlimited self-renewal capacity. Although pluripotency and differentiation have been examined extensively, the mechanisms responsible for self-renewal are poorly understood and are believed to involve an unusual cell cycle, epigenetic regulators and pluripotency-promoting transcription factors. Here we show that B-MYB, a cell cycle regulated phosphoprotein and transcription factor critical to the formation of inner cell mass, is central to the transcriptional and co-regulatory networks that sustain normal cell cycle progression and self-renewal properties of ESCs. Phenotypically, B-MYB is robustly expressed in ESCs and induced pluripotent stem cells (iPSCs), and it is present predominantly in a hypo-phosphorylated state. Knockdown of B-MYB results in functional cell cycle abnormalities that involve S, G2 and M phases, and reduced expression of critical cell cycle regulators like ccnb1 and plk1. By conducting gene expression profiling on control and B-MYB deficient cells, ChIP-chip experiments, and integrative computational analyses, we unraveled a highly complex B-MYB-mediated transcriptional network that guides ESC self-renewal. The network encompasses critical regulators of all cell cycle phases and epigenetic regulators, pluripotency transcription factors, and differentiation determinants. B-MYB along with E2F1 and c-MYC preferentially co-regulate cell cycle target genes. B-MYB also co-targets genes regulated by OCT4, SOX2 and NANOG that are significantly associated with stem cell differentiation, embryonic development, and epigenetic control. Moreover, loss of B-MYB leads to a breakdown of the transcriptional hierarchy present in ESCs. These results coupled with functional studies demonstrate that B-MYB not only controls and accelerates cell cycle progression in ESCs it contributes to fate decisions and maintenance of pluripotent stem cell identity.

    Khoshkbar Sadigh, Arash

    Part I: Dynamic Voltage Restorer In the present power grids, voltage sags are recognized as a serious threat and a frequently occurring power-quality problem and have costly consequence such as sensitive loads tripping and production loss. Consequently, the demand for high power quality and voltage stability becomes a pressing issue. Dynamic voltage restorer (DVR), as a custom power device, is more effective and direct solutions for "restoring" the quality of voltage at its load-side terminals when the quality of voltage at its source-side terminals is disturbed. In the first part of this thesis, a DVR configuration with no need of bulky dc link capacitor or energy storage is proposed. This fact causes to reduce the size of the DVR and increase the reliability of the circuit. In addition, the proposed DVR topology is based on high-frequency isolation transformer resulting in the size reduction of transformer. The proposed DVR circuit, which is suitable for both low- and medium-voltage applications, is based on dc-ac converters connected in series to split the main dc link between the inputs of dc-ac converters. This feature makes it possible to use modular dc-ac converters and utilize low-voltage components in these converters whenever it is required to use DVR in medium-voltage application. The proposed configuration is tested under different conditions of load power factor and grid voltage harmonic. It has been shown that proposed DVR can compensate the voltage sag effectively and protect the sensitive loads. Following the proposition of the DVR topology, a fundamental voltage amplitude detection method which is applicable in both single/three-phase systems for DVR applications is proposed. The advantages of proposed method include application in distorted power grid with no need of any low-pass filter, precise and reliable detection, simple computation and implementation without using a phased locked loop and lookup table. The proposed method has been verified

    Progress is reported on studies on hereditary anemias of mice. At present under study are four macrocytic anemias, four hemolytic anemias, nonhemolytic microcytic anemia, transitory siderocytic anemia, sex-linked iron-transport anemia, and the autoimmune hemolytic anemia of NZB. Each of these blood dyscrasias is caused by the action of a unique mutant gene, each of which determines the structure of different intracellular molecules, and thus controls a different metabolic process. Thus our wide range of different hereditary anemias has considerable potential for uncovering many different aspects of hemopoietic homeostatic mechanisms in the mouse.

It has gradually abandoned militant writing to become a historic object submitted to a critical view. Despite having been for a long time considered as a nearly forgotten period, it has of late aroused a renewed interest which is made evident by the extension of themes, and by the increasing weight of cultural history which penetrates political, social and religious history. However, the economic history, as well as the compared history of the Restorations in Europe still remains embryonic, in spite of some recent initiatives. | La historiografía francesa sobre la Restauración está marcada por algunos importantes jalones. Poco a poco ha ido escapando de la escritura militante para convertirse en un objeto histórico sometido a una mirada crítica.

A pesar de ello, la historia económica o la historia comparada de las Restauraciones en Europa se encuentran todavía en un estado embrionario, a pesar de algunas iniciativas recientemente puestas en marcha.

    With the translocation and release of 90 fishers (Pekania pennanti) from British Columbia to Olympic National Park during 2008–2010, the National Park Service and Washington Department of Fish and Wildlife accomplished the first phase of fisher restoration in Washington State. Beginning in 2013, we initiated a new research project to determine the current status of fishers on Washington’s Olympic Peninsula 3–5 years after the releases and evaluate the short-term success of the restoration program. Objectives of the study are to determine the current distribution of fishers and proportion of the recovery area that is currently occupied by fishers, determine several genetic characteristics of the reintroduced population, and determine reproductive success of the founding animals through genetic studies. During 2014, we continued working with a broad coalition of cooperating agencies, tribes, and nongovernmental organizations (NGO) to collect data on fisher distribution and genetics using noninvasive sampling methods. The primary sampling frame consisted of 157 24-square-kilometer hexagons (hexes) distributed across all major land ownerships within the Olympic Peninsula target survey area. In 2014 we expanded the study by adding 58 more hexes to an expanded study area in response to incidental fisher observations outside of the target area obtained in 2013; 49 hexes were added south and 9 to the east of the target area. During 2014, federal, state, tribal and NGO biologists and volunteers established three baited motion-sensing camera stations, paired with hair snaring devices, in 80 hexes; 69 in the targeted area 11 in the expansion areas. Each paired camera/hair station was left in place for approximately 6 weeks, with three checks on 2-week intervals. We documented fisher presence in 5 of the 80 hexagons, and identified 5 different fishers through a combination of microsatellite DNA analyses and camera detections.

    Adult skeletal muscle is endowed with regenerative potential through partially recapitulating the embryonic developmental program. Upon acute injury or in pathological conditions, quiescent muscle-resident stem cells, called satellite cells, become activated and give rise to myogenic progenitors that massively proliferate, differentiate, and fuse to form new myofibers and restore tissue functionality. In addition, a proportion of activated cells returns back to quiescence and replenish the pool of satellite cells in order to maintain the ability of skeletal muscle tissue to repair. Self-renewal is the process by which stem cells divide to make more stem cells to maintain the stem cell population throughout life. This process is controlled by cell-intrinsic transcription factors regulated by cell-extrinsic signals from the niche and the microenvironment. This chapter provides an overview about the general aspects of satellite cell biology and focuses on the cellular and molecular aspects of satellite cell self-renewal. To date, we are still far from understanding how a very small proportion of the satellite cell progeny maintain their stem cell identity when most of their siblings progress through the myogenic program to construct myofibers. © 2018 Elsevier Inc.

  17. Renewable Substitutability Index: Maximizing Renewable Resource Use in Buildings

    Directory of Open Access Journals (Sweden)

    Ravi S. Srinivasan

    2015-05-01

    Full Text Available In order to achieve a material and energy balance in buildings that is sustainable in the long run, there is an urgent need to assess the renewable and non-renewable resources used in the manufacturing process and to progressively replace non-renewable resources with renewables. Such progressive disinvestment in the non-renewable resources that may be substituted with renewable resources is referred to as “Renewable Substitutability” and if implemented, this process will lead to a paradigm shift in the way building materials are manufactured. This paper discusses the development of a Renewable Substitutability Index (RSI that is designed to maximize the use of renewable resources in a building and quantifies the substitution process using solar emergy (i.e., the solar equivalent joules required for any item. The RSI of a building or a building component, i.e., floor or wall systems, etc., is the ratio of the renewable resources used during construction, including replacement and maintenance, to the building’s maximum renewable emergy potential. RSI values range between 0 and 1.0. A higher RSI achieves a low-energy building strategy promoting a higher order of sustainability by optimizing the use of renewables over a building’s lifetime from formation-extraction-manufacturing to maintenance, operation, demolition, and recycle.

    'The purpose of this project is to develop a computer code for joint in-version of seismic and electrical data, to improve underground imaging for site characterization and remediation monitoring. The computer code developed in this project will invert geophysical data to obtain direct estimates of porosity and saturation underground, rather than inverting for seismic velocity and electrical resistivity or other geophysical properties. This is intended to be a significant improvement in the state-of-the-art of under-ground imaging, since interpretation of data collected at a contaminated site would become much less subjective. The schedule of this project is as follows: In the first year, investigators perform laboratory measurements of elastic and electrical properties of sand-clay mixtures containing various fluids. Investigators also develop methods of relating measurable geophysical properties to porosity and saturation by using rock physics theories, geostatistical, and empirical techniques together with available laboratory measurements. In the second year, investigators finish any necessary laboratory measurements and apply the methods developed in the first year to invert available borehole log data to predict measured properties of cores and sediments from a borehole. Investigators refine the inversion code in the third year and carry out a field experiment to collect seismic and electrical data. Investigators then use the inversion code to invert the field data to produce estimates of porosity and saturation in the field area where the data were collected. This report describes progress made in the first year of this three-year project.'

    This Pinellas County, Florida, Site Environmental Restoration Project Semiannual Progress Report for the 4.5 Acre Site describes environmental restoration activities for the 4.5 Acre Site located in Pinellas County, Largo, Florida (Figure 1). The former U.S. Department of Energy (DOE) Pinellas Plant facility consisted of the 4.5 Acre Site and what is now the STAR Center (Young - Rainey Science, Technology, and Research Center). Both the 4.5 Acre Site and the STAR Center are part of the overall Pinellas County, Florida, Site (Figure 2). The 4.5 Acre Site is located immediately northwest of the STAR Center, in the northeast quarter of Section 13, Township 30 South, Range 15 East. DOE owned this parcel from 1957 to 1972, at which time it was sold to a private landowner. During the period of DOE ownership, the property was used for the disposal of drums of waste resins and solvents. As a result of this practice, the surficial aquifer was impacted by volatile organic compounds (VOCs)—trichloroethene (TCE), cis-1,2-dichloroethene (cDCE), trans-1,2-dichloroethene (tDCE), vinyl chloride (VC), and benzene. Detailed background information for the site is contained in the Long-Term Surveillance and Maintenance Plan for the Pinellas Site (DOE 2016). That document and other site-related documents can be accessed at this website: http://www.lm.doe.gov/Pinellas/Sites.aspx. Recent remediation activities consist of the injection of emulsified soybean oil and the microorganism Dehalococcoides mccartyi (formerly known as Dehalococcoides ethenogenes) into the subsurface in February 2010 and again in July 2013 to enhance contaminant biodegradation (hereafter described as bioinjection). Monitoring the performance of these actions, in the form of monitoring well sampling, is ongoing.

    A reduction in energy consumption by the energy intensive sectors will be rewarded by a tax credit. The advantages of renewable sources of energy in terms of reducing emissions of carbon dioxide are extolled. The Government will reward the use of renewables through exemption from the Climate Change Levy. Many major companies are now committed to renewables and Shell predict that 50% of world energy will come from renewables by 2050. World-wide there is now 10,000 MW of installed wind power and the annual rate of growth is more than 20%. Other renewables such as biomass, energy from waste, solar power, hydropower, wind power and tidal power are discussed. The Government would like to see 10% of the UK's electricity coming from renewables by 2010. (UK)

    Restoration and preservation of coastal dunes is urgently needed because of the increasingly rapid loss and degradation of these ecosystems because of many human activities. These activities alter natural processes and coastal dynamics, eliminate topographic variability, fragment, degrade or eliminate habitats, reduce diversity and threaten endemic species. The actions of coastal dune restoration that are already taking place span contrasting activities that range from revegetating and stabilizing the mobile substrate, to removing plant cover and increasing substrate mobility. Our goal was to review how the relative progress of the actions of coastal dune restoration has been assessed, according to the ecosystem attributes outlined by the Society of Ecological Restoration: namely, integrity, health and sustainability and that are derived from the ecological theory of succession. We reviewed the peer reviewed literature published since 1988 that is listed in the ISI Web of Science journals as well as additional references, such as key books. We exclusively focused on large coastal dune systems (such as transgressive and parabolic dunefields) located on natural or seminatural coasts. We found 150 articles that included "coastal dune", "restoration" and "revegetation" in areas such as title, keywords and abstract. From these, 67 dealt specifically with coastal dune restoration. Most of the studies were performed in the USA, The Netherlands and South Africa, during the last two decades. Restoration success has been assessed directly and indirectly by measuring one or a few ecosystem variables. Some ecosystem attributes have been monitored more frequently (ecosystem integrity) than others (ecosystem health and sustainability). Finally, it is important to consider that ecological succession is a desirable approach in restoration actions. Natural dynamics and disturbances should be considered as part of the restored system, to improve ecosystem integrity, health and

    This article gives an overview of the process of license renewal for nuclear power plants. It explains what is meant by license renewal, the significance of license renewal, and goes over key elements involved in the process of license renewal. Those key elements are NRC requirements embodied in 10 CFR Part 54 (Reactor Safety) and 10 CFR Part 51 (Environmental Issues). In addition Industry Reports must be developed and reviewed. License renewal is essentially the process of applying for a 20 year extension to the original 40 year operating license granted for the plant. This is a very long term process, which involves a lot of preparation, and compliance with regulatory rules and guidelines. In general it is a process which is expected to begin when plants reach an operating lifetime of 20 years. It has provisions for allowing the public to become involved in the review process

    Full Text Available A review of the science and practice of ecosystem restoration led me to identify key ecological theories and concepts that are relevant to planning, implementing, and sustaining restoration efforts. From experience with actual restoration projects, I provide guidance for improving the restoration process. Despite an abundance of theory and guidance, restoration goals are not always achieved, and pathways toward targets are not highly predictable. This is understandable, since each restoration project has many constraints and unique challenges. To improve restoration progress, I advise that sites be designed as experiments to allow learning while doing. At least the larger projects can be restored in phases, each designed as experimental treatments to test alternative restoration approaches. Subsequent phases can then adopt one or more of the treatments that best achieved goals in earlier phases while applying new tests of other restoration measures. Both science and restoration can progress simultaneously. This phased, experimental approach (called “adaptive restoration” is an effective tool for improving restoration when monitoring, assessment, interpretation and research are integrated into the process.

    Renewable energy sources have a small environmental impact and can be easily integrated within existing structures. Moreover, the use of renewable energy sources can contribute to achieve a zero emission of carbon dioxide by 2100, provided an efficient environmental policy during the next 40 years. This includes a correct pricing policy of renewable energy sources with respect to nuclear energy and fossil fuel. The latter energy sources have been favoured in the past. In addition, an open market policy, the restructuring or conversion of existing international energy institutes, and international treaties for the protection of the natural environment are needed in view of achieving the zero carbon dioxide emission objective.

    The use of renewable energy is tightly connected to solving social problems in Estonia by creating more new jobs. It is essential that Estonia should increase the use of biofuels. One of the biofuels, firewood, has been used already for centuries. For wider use of renewable energy in Estonia, it is not enough to rely only on enterprices. Rather, before any serious progress can take place, the state should create the appropriate legal environment. Due to its many social and environmental aspects, renewable energy is more important to the state than a sole enterprice. Unfortunately, Estonian government has been delaying its duties. Estonia has two resources that should be taken advantage of, fertile spare land and people still used to the country life. The country people would get work by growing different energy crops on the spare land. (author)

    The Energy Committee of the Royal Swedish Academy of Sciences has in a series of projects gathered information and knowledge on renewable energy from various sources, both within and outside the academic world. In this article, we synthesize and summarize some of the main points on renewable energy from the various Energy Committee projects and the Committee's Energy 2050 symposium, regarding energy from water and wind, bioenergy, and solar energy. We further summarize the Energy Committee's scenario estimates of future renewable energy contributions to the global energy system, and other presentations given at the Energy 2050 symposium. In general, international coordination and investment in energy research and development is crucial to enable future reliance on renewable energy sources with minimal fossil fuel use.

    Ambitious Danish and European energy and environment objectives make a point of using renewable energy sources in the electricity supply. Denmark has been leading country in successful development and commercialization of wind turbines and is as yet one of the leading manufacturers of the world. Danish governments have successfully invested a lot in this development. Other countries have spent more money without achieving a similar success. The questions are why things have gone so well in Denmark and if the Danish success can be repeated for other renewable energy technologies. The starting point of this book is that a political decision on subsidizing the developmental process of a specific technology not in itself guarantees that the technology will turn out reliable and efficient enough to compete successfully in a liberalized electricity market. An understanding of this development is necessary in order to affect a technological development. This book goes through the development of different renewable energy technologies and two theories used for discussing the technological development: experience curves and innovation theory. Based on the discussions and a description of causal relations, an analytical model for different phases of renewable energy technologies' developmental progress and technological life cycle is made. The model is used for evaluating the subsidies for chosen renewable technologies in Denmark. With wind energy as example an analysis of what went well or badly, what might be done and which actions might be efficient is made. (BA)

  14. Economics of nuclear and renewables

    Khatib, Hisham; Difiglio, Carmine

    2016-01-01

    This paper provides an assessment of the economic challenges faced by both nuclear power and “new” renewable electricity technologies. The assessment reflects the need to incorporate new renewables into power grids and issues faced in dispatching power and their effect on traditional electricity technologies as well as the need for transmission extension and/or grid reinforcement. Wider introduction of smart grids and the likely demise of nuclear in some OECD countries are bound to enhance the future prospects for new renewables. However, their immediate future expansion will depend on continued subsidies, which are becoming difficult to sustain in present economic circumstances. Development of large energy storage facilities and carbon pricing could significantly enhance future renewable energy prospects. Correspondingly, expanding renewable energy, in spite of their popularity with some governments and sections of the public, is likely to face challenges which will slow their present rapid progress. Nuclear is now shied away from in many industrialized countries and having mixed prospects in developing economies. In many instances, it suffers from high initial costs, long lead times and often excessive construction delays. Nuclear power also faces challenging risks – investment as well as regulatory. In contrast to renewables, its share of global energy consumption is declining. - Highlights: •Renewables are increasing their energy share. •Renewables system cost is higher than their production cost. •Nuclear share is not increasing and their costs are not reduced. •Discount rate and subsidies are important in economics of renewables and nuclear.

    If one compares the progress in research and development of renewable energy applications with the finding which has been granted to these activities during the 23 years after the first oil shock, one cannot but be very impressed. It is indicated in this paper hoe comprehensive the potential of renewable energy is. One should take into account that the methods described form a broad interdisciplinary field in contrast to fossil and nuclear technologies. From technical point of view the present and future energy demand can be met by the broad spectrum of renewable energies in combination with energy conservation. Many of these techniques are already economically competitive: solar architecture, wind energy, hydropower, low temperature heat production, photovoltaic for remote areas, various types of biomass application, geothermal energy although not exactly renewable. The future of renewable energies will depend on opening markets for these techniques

    The objective of this paper is to present the ecological impact on environment as a consequence of more than 30 years of activity in the field of uranium exploration, mining and ore processing in Romania and a brief description of the measures taken for limiting the effects of contamination on the affected zones including the proposed restructuring and rehabilitation programmes. The Autonomous Regie for Rare Metals (RAMR), the coordinator of the activities in the uranium field is responsible to implement the provisions of the IAEA Technical Cooperation Project on Environmental Restoration in Central and Eastern Europe joined by Romania in 1993. The characterization of radioactively contaminated areas is dealt with broadly under two categories, one pertaining to sites where the mining and milling activities have already ceased and the other where the units are still operational but are going to be closed down in the near future and will be placed under surveillance. Generally speaking, the activity in the uranium field is developed by observing the national Norms of Nuclear Safety for the Activity of Geological Investigation, Mining and Milling of Nuclear Raw Material. This report includes an evaluation of the necessary investments for the first stage of the programme dealing with the environmental restoration and the necessary research activities. This will be followed by studies for closing down and surveillance of the mines with special problems taking into account their depth and complex hydrology

    Interim restorations are a critical component of fixed prosthodontic treatment, biologically and biomechanically. Interim restoration serves an important diagnostic role as a functional and esthetic try-in and as a blueprint for the design of the definitive prosthesis. When selecting materials for any interim restoration, clinicians must consider physical properties, handling properties, patient acceptance, and material cost. Although no single material meets all the requirements and material classification alone of a given product is not a predictor of clinical performance, bis-acryl materials are typically best suited to single-unit restorations, and poly(methylmethacrylate) interim materials are generally ideal for multi-unit, complex, long-term, interim fixed prostheses. As with most dental procedures, the technique used for fabrication has a greater effect on the final result than the specific material chosen.

    Renewable energy markets, industries, and policy frameworks have evolved rapidly in recent years. The Renewables Global Status Report provides a comprehensive and timely overview of renewable energy market, industry, investment, and policy developments worldwide. It relies on the most recent data available, provided by many contributors and researchers from around the world, all of which is brought together by a multi-disciplinary authoring team. The report covers recent developments, current status, and key trends; by design, it does not provide analysis or forecasts. This latest Renewables Global Status Report saw: a shift in investment patterns that led to a global decrease in clean energy investment; continuing growth in installed capacity due to significant technology cost reductions and increased investment in developing countries; renewables progressively supplementing established electricity systems, demonstrating that the implementation of suitable policies can enable the successful integration of higher shares of variable renewables; and the emergence of integrated policy approaches that link energy efficiency measures with the implementation of renewable energy technologies.

    Full Text Available Rehabilitation of a patient with severely worn dentition after restoring the vertical dimension is a complex procedure and assessment of the vertical dimension is an important aspect in these cases. This clinical report describes the full mouth rehabilitation of a patient who was clinically monitored to evaluate the adaptation to a removable occlusal splint to restore vertical dimension for a period 1 month and provisional restorations to determine esthetic and functional outcome for a period of 3 months. It is necessary to recognizing that form follows function and that anterior teeth play a vital role in the maintenance of oral health. Confirmation of tolerance to changes in the vertical dimension of occlusion (VDO is of paramount importance. Articulated study casts and a diagnostic wax-up can provide important information for the evaluation of treatment options. Alteration of the VDO should be conservative and should not be changed without careful consideration.

    The impact of male hair loss as a personal and social marker of aging is tremendous and its persistence as a human concern throughout recorded history places it in the forefront of male concern about the physical signs of aging. Restoration of the frontal hairline has the visual effect of re-establishing facial symmetry and turning back time. Follicular unit transplantation has revolutionized hair restoration, with its focus on redistributing large numbers of genetically stable hair to balding scalp in a natural distribution. Follicular unit hair restoration surgery is a powerful tool for the facial plastic surgeon in male aesthetic facial rejuvenation because it offers high-impact, natural-appearing results with minimal downtime and risk for adverse outcome.

    2017-01-01

    The first version of REN21's Renewables Global Futures Report (GFR) published in January 2013 identified a panorama of likely future debates related to the renewable energy transition. As a reflection of the wide range of contemporary thinking by the many experts interviewed for the report, it did not present just one vision of the future but rather a 'mosaic' of insights. Given the positive feedback in response to the first edition, a new edition has been prepared, continuing where the last one left off. The objective of this report is to gather opinions about the feasibility of a 100% renewable energy future, and the macro-economic impacts it would entail. In so doing, the report reflects on the debates of 2013, and tracks their evolution to the present time. Some remain, some have changed, some have been overtaken by progress, and new ones have arisen. They are summarised here as the Great Debates in renewable energy. The questionnaire for the survey was developed in close cooperation between the REN21 Secretariat, the Institute for Sustainable Future (ISF) of the University of Technology Sydney/Australia (UTS) and the Institute for Advanced Sustainability Studies (IASS) in Potsdam/Germany. It covered the following topics: 1. How much renewables?; 2. Power sector; 3. Heating and cooling; 4. Transport; 5. Storage; 6. Demand-side management and energy efficiency; 7. Integration of sectors; 8. Macro-economic considerations; 9. Technology and costs; 10. Policy; 11. Cities; 12. Distributed renewable energy/energy access; 13. Barriers/challenges/enablers. 114 experts were interviewed in total; the average interview time was approximately one hour. The interviews were conducted between May and October 2016. The questionnaire was also mirrored in an online version and used both by interviewers and interviewees to record the interview process. Interviewees were selected from the following regions: Africa, Australia and Oceania, China, Europe, India, Japan, Latin America

  17. Renewing governance.

    Science.gov (United States)

    Loos, Gregory P

    2003-01-01

    Globalization's profound influence on social and political institutions need not be negative. Critics of globalization have often referred to the "Impossible Trinity" because decision-making must 1. respect national sovereignty, 2. develop and implement firm regulation, and 3. allow capital markets to be as free as possible. To many, such goals are mutually exclusive because history conditions us to view policy-making and governance in traditional molds. Thus, transnational governance merely appears impossible because current forms of governance were not designed to provide it. The world needs new tools for governing, and its citizens must seize the opportunity to help develop them. The rise of a global society requires a greater level of generality and inclusion than is found in most policy bodies today. Politicians need to re-examine key assumptions about government. States must develop ways to discharge their regulatory responsibilities across borders and collaborate with neighboring jurisdictions, multilateral bodies, and business. Concepts such as multilateralism and tripartism show great promise. Governments must engage civil society in the spirit of shared responsibility and democratic decision-making. Such changes will result in a renewal of the state's purpose and better use of international resources and expertise in governance.

    The Young - Rainey STAR Center (Science, Technology, and Research Center) at the Pinellas County, Florida, Site is a former U.S. Department of Energy (DOE) facility constructed in the mid-1950s. The 96-acre STAR Center is located in Largo, Florida, and lies in the northeast quarter of Section 13, Township 30 South, Range 15 East (Figure 1). While it was owned by DOE, the purpose of the site was to develop and manufacture components for the nation’s nuclear weapons program. In 1987, the U.S. Environmental Protection Agency (EPA) performed a Resource Conservation and Recovery Act Facility Assessment (EPA 1988) at the site to gather information on potential releases of hazardous materials. In February of 1990, EPA issued a Hazardous and Solid Waste Amendments permit to DOE, requiring DOE to investigate and perform remediation activities in those areas designated as solid-waste management units (SWMUs) contaminated by hazardous materials resulting from DOE operations. A total of 17 SWMUs were identified and investigated at the STAR Center. By 1997, 13 of the 17 SWMUs had been remediated or approved for no further action. More recently, the Florida Department of Environmental Protection (FDEP) executed Conditional Site Rehabilitation Completion Orders for the Northeast Site and the Wastewater Neutralization Area on July 27, 2016, stating that no further action is required for those SWMUs. The Building 100 Area (a combination of the Old Drum Storage Site and the Building 100-Industrial Drain Leaks SWMUs) comprises the only two active SWMUs at the STAR Center (Figure 2). This document serves as the semiannual progress report for the SWMUs by providing the results of recent monitoring activities and a summary of ongoing and projected work. The STAR Center is owned by the Pinellas County Industrial Development Authority, but DOE is responsible for remediation activities at the site. Additional background information for the site is contained in the Long-Term Surveillance

    2012-01-01

    Criminal defendants adjudicated incompetent to stand trial are typically hospitalized for competence restoration in state institutions. Prolonged restoration hospitalizations involve civil rights concerns and increasing financial costs, and there remains interest in determining which individuals are likely to be successfully restored. We retrospectively reviewed hospital records of 455 male defendants admitted to a forensic treatment center for competence restoration in an effort to determine whether psychiatric diagnoses, demographic factors, or psycholegal abilities were predictive of successful or failed restoration. At varying stages of restoration efforts, psychotic disorder, mental retardation, and previous state hospitalization predicted unsuccessful restoration, while substance use and personality disorders were predictive of successful restoration. Psycholegal abilities were predictive of successful restoration and appeared to form a continuum, with basic behavior and outlook, factual legal understanding, and rational attorney assistance factors demonstrating progressively increased importance in successful restoration.

  13. Renewal of radiological equipment.

    Science.gov (United States)

    2014-10-01

    In this century, medical imaging is at the heart of medical practice. Besides providing fast and accurate diagnosis, advances in radiology equipment offer new and previously non-existing options for treatment guidance with quite low morbidity, resulting in the improvement of health outcomes and quality of life for the patients. Although rapid technological development created new medical imaging modalities and methods, the same progress speed resulted in accelerated technical and functional obsolescence of the same medical imaging equipment, consequently creating a need for renewal. Older equipment has a high risk of failures and breakdowns, which might cause delays in diagnosis and treatment of the patient, and safety problems both for the patient and the medical staff. The European Society of Radiology is promoting the use of up-to-date equipment, especially in the context of the EuroSafe Imaging Campaign, as the use of up-to-date equipment will improve quality and safety in medical imaging. Every healthcare institution or authority should have a plan for medical imaging equipment upgrade or renewal. This plan should look forward a minimum of 5 years, with annual updates. Teaching points • Radiological equipment has a definite life cycle span, resulting in unavoidable breakdown and decrease or loss of image quality which renders equipment useless after a certain time period.• Equipment older than 10 years is no longer state-of-the art equipment and replacement is essential. Operating costs of older equipment will be high when compared with new equipment, and sometimes maintenance will be impossible if no spare parts are available.• Older equipment has a high risk of failure and breakdown, causing delays in diagnosis and treatment of the patient and safety problems both for the patient and the medical staff.• Every healthcare institution or authority should have a plan for medical imaging equipment upgrade or replacement.

    2017-07-01

    Full Text Available The last restoration of Michelangelo’s frescoes in the Sistine Chapel was directed and conducted by the internal staff of the Vatican Museums, in the period from June 1980 to April 1994. The historical importance of this restoration is found in the recovery of the unexpected chromatic tones used by Michelangelo and hidden for centuries by the dust, black smoke and grease produced by candles and braziers, and by the animal glue, gum resin and ox bile used by restorers in the past to revive the colors. The important result was obtained without any risk, thanks to developments in the field of methods and materials, the progress made in diagnostics, and the elaboration of a theory of restoration (Brandi C. 1950 which still acts as a support to the scientific and technical guidelines used in restoration today. The good preservation of the frescoes in the Chapel is entrusted to a filter and air conditioning system which was renewed and upgraded in 2015, and to modern LED lighting installed in the same year. The cleaning of the frescoes, which were almost perfectly preserved thanks to Michelangelo’s technique, allowed us to study the artist’s painting technique and to learn that some of the techniques he employed in marble sculpting were applied to his painting, and that he introduced novel methods, such as the technique used to give three-dimensionality to figures or his particular brushstrokes, which anticipated divisionism and pointillism.

  17. Renewable energy sources and Estonian national interests

    International Nuclear Information System (INIS)

    Veski, Rein

    2002-01-01

    There is only one national level document, The Long-term National Development Plan for the Fuel and Energy sector, regulating the development of renewable energy for Estonia. It was approved by the Parliament (Riigikogu) in 1998. This document planned a 2/3 (66,7%) increase in the share of renewable (according to the document: peat, biofuels and other renewables) to the year 2010 against 1996. At the same time a decrease of the share of domestic oil shale was planned 1/5 to the year 2010 against 1995. That means the use of domestic energy sources, both renewable and non-renewable, will decrease by 16,8% altogether. In reality the rapid projected growth of renewables in Estonia (+66,7% between 1996 and 2010) was changed with decrease of 20% by 2000. So the security of supply must shift to the first place in Estonia. It is also an issue of national sovereignty. Estonia is rich in renewable energy sources, mainly in wood, peat and wind, to achieve the goals set in the National Development Plan. Forest resources amount 352,7, total felling 6,44, allowed felling 7,81 million cubic meters solid volume in 2000. The future of fuel peat usage in Estonia is uncertain, as most of the EU member states, which have burned up their peat resources and/or drained their mires do not consider peat as a renewable fuel. Obviously Estonia has to explain its opinion about the renewability of its resources. Although progress is needed in all directions of additional use of all renewable energy sources in tactical consideration finance must be directed first to guarantee better use of wastes of woodworking and timber industry

    The United Nations Economic Commission for Europe (UNECE) covers a large and diverse region comprising 56 member states. These countries have different energy situations and vary in their potential for and progress in renewable energy and energy efficiency. The present report covers 17 UNECE countries, with the aim of establishing a data baseline and providing a general overview of their renewable energy situations. Over the past decade, the national governments of the selected countries have been working actively to leverage this renewable energy potential. Energy security and access to reliable, affordable, sustainable and modern energy are the key concerns driving renewable energy deployment. These countries require more substantial investment to fully realise its renewable potential and to bring innovative solutions to tackle their energy challenges, such as heating in urban and rural areas. A reliable data baseline is a pre-requisite and an enabler for more investment activity. The UNECE has contributed actively to fulfilling the 17 countries' aspirations in renewable energy by providing them with a platform for collaboration among UNECE member states. In 2014, a UNECE Group of Experts on Renewable Energy was established to step up these efforts. Its mandate is to carry out action-oriented, practical activities to significantly increase the uptake of renewable energy, in line with the United Nations Secretary-General's Sustainable Energy for All (SE4All) initiative. This UNECE Renewable Energy Status Report strives to present analysis of up-to-date data and information on the status of renewable energy and energy efficiency in the selected countries of the UNECE region

    1999-01-01

    In spite of increased attention to wetland conservation following the Ramsar Convention on Wetlands of International Importance, the peat-harvesting industry in many countries is still interested in the further exploitation of peatlands. In some of the most industrialised countries, all natural peatlands have already been lost. In others, only small areas of native peatland remain. Among other possible uses for cut-over peatlands, peatland restoration is one: there is an urgent need for the development of measures for regenerating peat-accumulation processes. The redevelopment of a fen or bog peat landscape is a long-term process, which will probably take centuries. The restoration of any peatland may therefore be considered successful if the outcome is the development and growth of plant communities able to produce peat. The renewal of the hydrological regime of such areas is a major factor which determines the re-colonisation of cut-over peat fields by peat-forming plants. The aim of this paper is to give a brief survey of wetlands, and especially of peatland restoration options, for use in terminated peat-cuttings. It aims to show how peatland management may be made sustainable by means of existing and tried methods and principles, with the goal of returning cut-over peat fields to their former peat-accumulating state. A glossary of peat and peatland terminology is included 105 refs, 5 figs

    Renewable energy facilities have been installed in many regions, because of their possibility to be an alternative to fossil fuels for mitigating global warming. Besides the profitability of renewable energy businesses, indirect economic effects of installing renewable energy facilities should be clarified. This study examines the possibility that the renewable energy facilities give renewed impetus to regional economic progress. The economic effects are analysed with input-output techniques in a rural area in Japan. As a consequence, both positive and negative effects on the rural economy are derived. In addition, we will focus on the changes in sectors such as construction, business services, banking, etc. as a result of economic activities for renewable systems. The business benefits of renewable energy system are discussed. (author)

    1993-07-01

    The Lawrence Berkeley Laboratory (LBL) has applied to the California Environmental Protection Agency, Department of Toxic Substances Control (DTSC), for renewal of its Hazardous Waste Handling Facility Permit. A permit is required under Resource Conservation and Recovery Act (RCRA) regulations. The permit will allow LBL to continue using its current hazardous waste handling facility, upgrade the existing facility, and construct a replacement facility. The new facility is scheduled for completion in 1995. The existing facility will be closed under RCRA guidelines by 1996. As part of the permitting process, LBL is required to investigate areas of soil and groundwater contamination at its main site in the Berkeley Hills. The investigations are being conducted by LBL`s Environmental Restoration Program and are overseen by a number of regulatory agencies. The regulatory agencies working with LBL include the California Environmental Protection Agency`s Department of Toxic Substances Control, the California Regional Water Quality Control Board, the Bay Area Air Quality Management District, the East Bay Municipal Utilities District, and the Berkeley Department of Environmental Health. RCRA requires that the public be informed of LBL`s investigations and site cleanup, and that opportunities be available for the public to participate in making decisions about how LBL will address contamination issues. LBL has prepared this Community Relations Plan (CRP) to describe activities that LBL will use to keep the community informed of environmental restoration progress and to provide for an open dialogue with the public on issues of importance. The CRP documents the community`s current concerns about LBL`s Environmental Restoration Program. Interviews conducted between February and April 1993 with elected officials, agency staff, environmental organizations, businesses, site neighbors, and LBL employees form the basis for the information contained in this document.

    This paper builds on IEA publications, Deploying Renewables, Principles for Effective Policies and Deploying Renewables, Best and Future Policy Practice, that discuss the 'integrated policy approach,' whereby renewable energy technologies require different support policies at different stages of their maturity pathways. The paper discusses how the integrated policy approach applies to renewable heat. It attempts to provide guidance for policy-makers on renewable heat throughout the different phases of the policy lifecycle, allowing for the specific challenges of renewable heat and needs of the many stakeholders involved. Stimulating a market for heat involves challenges that are different and, often, more difficult to overcome than in the electricity and transport sectors.

    The main objectives of this thesis are: to investigate technological change and cost reduction for a number of renewable electricity technologies by means of the experience curve approach; to address related methodological issues in the experience curve approach, and, based on these insights; and to analyze the implications for achieving the Dutch renewable electricity targets for the year 2020 within a European context. In order to meet these objectives, a number of research questions have been formulated: What are the most promising renewable electricity technologies for the Netherlands until 2020 under different technological, economic and environmental conditions?; To what extent is the current use of the experience curve approach to investigate renewable energy technology development sound, what are differences in the utilization of this approach and what are possible pitfalls?; How can the experience curve approach be used to describe the potential development of partially new energy technologies, such as offshore wind energy? Is it possible to describe biomass fuel supply chains with experience curves? What are the possibilities and limits of the experience curve approach when describing non-modular technologies such as large (biomass) energy plants?; What are the main learning mechanisms behind the cost reduction of the investigated technologies?; and How can differences in the technological progress of renewable electricity options influence the market diffusion of renewable electricity technologies, and what implications can varying technological development and policy have on the implementation of renewable electricity technologies in the Netherlands? The development of different renewable energy technologies is investigated by means of some case studies. The possible effects of varying technological development in combination with different policy backgrounds are illustrated for the Netherlands. The thesis focuses mainly on the development of investment

    India has done a significant progress in the power generation in the country. The installed generation capacity was 1300 megawatt (MW) at the time of Independence i.e. about 60 years back. The total generating capacity anticipated at the end of the Tenth Plan on 31-03-2007, is 1, 44,520 MW which includes the generation through various sectors like Hydro, Thermal and Nuclear. Emphasis is given to the renewable energy programme towards gradual commercialization. This programme is looked after by the Ministry of Non-Conventional Sources of energy. Since the availability of fossil fuel is on the decline therefore, in this backdrop the norms for conventional or renewable sources of energy (RSE) is given importance not only in India but has attracted the global attention. The main items under RSE are as follows: (i) Hydro Power (ii) Solar Power (iii) Wind Power (iv) Bio-mass Power (v) Energy from waste (vi) Ocean energy, and (vii) Alternative fuel for surface transportation. Evolution of power transformer technology in the country during the past five decades is quite impressive. There are manufacturers in the country with full access to the latest technology at the global level. Some of the manufacturers have impressive R&D set up to support the technology. Renewable energy is very much promoted by the Chinese Government. At the same time as the law was passed, the Chinese Government set a target for renewable energy to contribute 10% of the country's gross energy consumption by 2020, a huge increase from the current 1%. It has been felt that there is rising demand for energy, food and raw materials by a population of 2.5 billion Chinese and Indians. Both these countries have large coal dominated energy systems in the world and the use of fossil fuels such as coal and oil releases carbon dioxide (CO2) into the air which adds to the greenhouse gases which lead to global warming.

    A Renewable Energy Exporters Network (REEN) has recently been established, following a meeting of renewable energy exporters and government agencies on 30 October 2000. REEN will assist the Australian renewable energy industry to take advantage of the opportunities offered by the burgeoning global market for renewable energy goods and services. Recent estimates of the significant potential global growth is renewable energy demand have reinforced the industry and Government's view that, in the medium to long-term, growth in the Australian renewable energy industry will largely depend on capturing export market share. Expanding the export market was identified as a crucial component in the Renewable Energy Action Agenda, developed jointly by industry and Government and released in June 2000. It was estimated that, for the industry to achieve its vision of sales of $4 billion per year by 2010, exports would need to comprise approximately 50% of the forecast growth in sales. As such, the need for a specific export strategy for the Australian renewable energy industry was recognised in the Action Agenda, and the establishment of the REEN is one of the first initiatives undertaken as part of the Renewable Energy Export Strategy. The REEN comprises approximately 50 export-ready renewable energy companies, the Department of Industry, Science and Resources, Austrade, and Stage Government agencies such as NSW's Sustainable Energy Development Authority. The Export Network will operate electronically, with face-to-face meetings held as appropriate. The Department of Industry, Science and Resources will facilitate the Export Network and has published a website at www.isr.gov.au/industry/reen. The site includes: a members directory; a discussion forum; information on opportunities to showcase Australian renewable; energy products and services; and Iinks to sites containing information that may be useful to renewable energy exporters.

    During the next 10 years, nuclear plant license renewal is expected to become a significant issue. Recent Electric Power Research Institute (EPRI) studies have shown license renewal to be technically and economically feasible. Filing an application for license renewal with the Nuclear Regulatory Commission (NRC) entails verifying that the systems, structures, and components essential for safety will continue to perform their safety functions throughout the license renewal period. This paper discusses the current proposed requirements for this verification and the current industry knowledge regarding age-related degradation of structures. Elements of a license renewal program incorporating NRC requirements and industry knowledge including a schedule are presented. Degradation mechanisms for structural components, their significance to nuclear plant structures, and industry-suggested age-related degradation management options are also reviewed

    In order to provide for the continuity of the current generation of nuclear power plant operating licenses and at the same time ensure the health and safety of the public, and the quality of the environment, the US Nuclear Regulatory Commission (NRC) established a goal of developing and issuing regulations and regulatory guidance for license renewal in the early 1990s. This paper will discuss some of those activities underway to achieve this goal. More specifically, this paper will discuss the Commission's regulatory philosophy for license renewal and the two major license renewal rule makings currently underway. The first is the development of a new Part 54 to address procedural and technical requirements for license renewal; the second is a revision to existing Part 51 to exclude environmental issues and impacts from consideration during the license renewal process.

    Over the past three years, the Union of Concerned Scientists (UCS) has evaluated the potential for using renewable energy for electricity in the Midwest, and has been carrying out a multifaceted effort to expand the use of renewables in the region. The UCS study presents a strategy for developing renewable-electric technologies and resources in 12 midwestern states. UCS analysts used a geographic information system (GIS) to create data-bases of renewable resources, land uses, vegetation cover, terrain elevation and locations of utility transmission lines, and to analyze and present information on a .6 mi x .6 mi (1 km x 1 km) grid scale. In addition, UCS developed a model to calculate the net employment impact of renewable versus conventional electricity technologies on a state-by-state basis. In evaluating the costs and benefits of renewable energy sources, UCS analysts explored a cost assessment that accounted for the impact of pollution from fossil fuels on energy resource cost. Researchers also considered the risks associated with fuel-price volatility, environmental regulation, construction lead times and other uncertainties. Finally, UCS researchers suggested steps to remove the institutional, regulatory and legislative barriers that inhibit renewable energy development, and proposed policies to expand the use of the region's renewable resources. The UCS analysis showed that wind is currently the least expensive renewable resource. UCS also found numerous opportunities to expand biomass-electric generation in the near term, such as converting small coal-fired power plants to wood fuel, making greater use of logging residues and co-firing a small percentage of biomass with fossil fuel at large power plants

    Given that few ecosystems on the Earth have been unaffected by humans, restoring them holds great promise for stemming the biodiversity crisis and ensuring ecosystem services are provided to humanity. Nonetheless, few studies have documented the recovery of ecosystems globally or the rates at which ecosystems recover. Even fewer have addressed the added benefit of actively restoring ecosystems versus allowing them to recover without human intervention following the cessation of a disturbance. Our meta-analysis of 400 studies worldwide that document recovery from large-scale disturbances, such as oil spills, agriculture and logging, suggests that though ecosystems are progressing towards recovery following disturbances, they rarely recover completely. This result reinforces conservation of intact ecosystems as a key strategy for protecting biodiversity. Recovery rates slowed down with time since the disturbance ended, suggesting that the final stages of recovery are the most challenging to achieve. Active restoration did not result in faster or more complete recovery than simply ending the disturbances ecosystems face. Our results on the added benefit of restoration must be interpreted cautiously, because few studies directly compared different restoration actions in the same location after the same disturbance. The lack of consistent value added of active restoration following disturbance suggests that passive recovery should be considered as a first option; if recovery is slow, then active restoration actions should be better tailored to overcome specific obstacles to recovery and achieve restoration goals. We call for a more strategic investment of limited restoration resources into innovative collaborative efforts between scientists, local communities and practitioners to develop restoration techniques that are ecologically, economically and socially viable. © 2018 The Author(s).

    With limited indigenous conventional energy resources, Taiwan imports over 99% of its energy supply from foreign countries, mostly from the Middle East. Developing independent renewable energy resources is thus of priority concern for the Taiwanese government. A medium subtropical island surrounded by the Pacific Ocean, Taiwan has enormous potential to develop various renewable energies, such as solar energy, biomass energy, wind power, geothermal energy, hydropower, etc. However, owing to the importance of conventional fossil energy in generating exceptionally cheap electricity, renewable energy has not yet fully developed in Taiwan, resulting from a lack of market competition. Consequently, numerous promotional and subsidy programs have recently been proclaimed by the Taiwanese government, focused on the development of various renewables. This study reviews the achievements, polices and future plans in this area. (author)

The relevance of ACRE to developing country communities which lack reliable, adequate power supplies, is discussed. The opportunities for mutual collaboration between Australia and the developing countries in the application of renewable energy have never been stronger. Renewable energy promises real advantages to those who deploy it wisely, as well as significant job creation. Education at all level together with operational training, public awareness of what is possible and increased system reliability, are also vital ingredients for acceptance of these new technologies. They underpin successful commercialisation. The author concludes with the hope for a united international cooperative approach to the development of the renewable energy industry. (author)

  19. Promoting renewable energy technologies

    Technologies using renewable energy sources are receiving increasing interest from both public authorities and power producing companies, mainly because of the environmental advantages they procure in comparison with conventional energy sources. These technologies can be substitution for conventional energy sources and limit damage to the environment. Furthermore, several of the renewable energy technologies satisfy an increasing political goal of self-sufficiency within energy production. The subject of this thesis is promotion of renewable technologies. The primary goal is to increase understanding on how technological development takes place, and establish a theoretical framework that can assist in the construction of policy strategies including instruments for promotion of renewable energy technologies. Technological development is analysed by through quantitative and qualitative methods. (BA)

    With limited indigenous conventional energy resources, Taiwan imports over 99% of its energy supply from foreign countries, mostly from the Middle East. Developing independent renewable energy resources is thus of priority concern for the Taiwanese government. A medium subtropical island surrounded by the Pacific Ocean, Taiwan has enormous potential to develop various renewable energies, such as solar energy, biomass energy, wind power, geothermal energy, hydropower, etc. However, owing to the importance of conventional fossil energy in generating exceptionally cheap electricity, renewable energy has not yet fully developed in Taiwan, resulting from a lack of market competition. Consequently, numerous promotional and subsidy programs have recently been proclaimed by the Taiwanese government, focused on the development of various renewables. This study reviews the achievements, polices and future plans in this area. (author)

    Spurred by innovation, increased competition, and policy support in a growing number of countries, renewable energy technologies have achieved massive technological advances and sharp cost reductions. Renewables have come to the forefront of the global energy transition, with nearly every country adopting a renewable energy target. Yet progress has been uneven in different countries and sectors. Technology and financial risks still hamper the expansion of renewables into new markets. As the power sector develops further, the increased adoption of variable renewables like solar and wind requires more flexible systems. Compared to power generation, the regulatory framework for end-use sectors lags behind. This report, prepared jointly by the International Renewable Energy Agency (IRENA), the International Energy Agency (IEA) and the Renewable Energy Policy Network for the 21. Century (REN21), identifies key barriers and highlights policy options to boost renewable energy deployment. After reviewing current policies and targets worldwide, it examines sector-specific policies for heating and cooling, transport and power, as well as measures for integrating variable renewables. An updated policy classification and terminology list can serve as a global reference for renewable energy policy instruments. Among the key findings: Renewable energy policies must focus on end-use sectors, not just power generation; The use of renewables for heating and cooling requires greater policy attention, including dedicated targets, technology mandates, financial incentives, generation-based incentives, and carbon or energy taxes; Policies in the transport sector require further development, including integrated policies to de-carbonise energy carriers and fuels, vehicles and infrastructure; Policies in the power sector must also evolve further to address new challenges. Measures are needed to support the integration of variable renewable energy, taking into account the specific

    2004-01-01

    The purpose of this paper is to provide information about license renewal process, as defined by Nuclear Regulatory Commission (NRC). The Atomic Energy Act and NRC regulations limit commercial power reactor licenses to an initial 40 years but also permit such licenses to be renewed. This original 40-year term for reactor licenses was based on economic and antitrust considerations not on limitations of nuclear technology. Due to this selected time period; however, some structures and components may have been engineered on the basis of an expected 40-year service life. The NRC has established a timely license renewal process and clear requirements codified in 10 CFR Part 51 and 10 CFR Part 54, that are needed to assure safe plant operation for extended plant life. The timely renewal of licenses for an additional 20 years, where appropriate to renew them, may be important to ensuring an adequate energy supply during the first half of the 21st Century. License renewal rests on the determination that currently operating plants continue to maintain adequate levels of safety, and over the plant's life, this level has been enhanced through maintenance of the licensing bases, with appropriate adjustments to address new information from industry operating experience. Additionally, NRC activities have provided ongoing assurance that the licensing bases will continue to provide an acceptable level of safety. This paper provides additional discussion of license renewal costs, as one of key elements in evaluation of license renewal justifiability. Including structure of costs, approximately value and two different approaches, conservative and typical. Current status and position of Nuclear Power Plant Krsko, related to license renewal process, will be briefly presented in this paper. NPP Krsko is designed based on NRC Regulations, so requirements from 10 CFR 51, and 10 CFR 54, are applicable to NPP Krsko, as well. Finally, this paper will give an overview of current status of

    The tax loads associated with constructing and owning current and advanced solar central receiver, biomass-electric, and flash and binary cycle geothermal projects are compared to the tax loads incurred by natural gas-fired generation matched in size, hours of operation, and technology status. All but one of the eight renewable projects carry higher tax burdens under current tax codes. These higher tax loads proportionately reduce the competitiveness of renewables. Three tax neutralizing policies are applied to the renewable projects, each restoring competitiveness for some of the projects. The results show that RD and D must be accompanied with such public initiatives as tax neutrality in order for the majority of renewable projects to compete with advanced gas turbines in the emerging electric services market

Managers need more firmly grounded process-understanding. The key idea of this paper is to dynamically conceptualize key activities of strategic renewal, and possible sources of break-down as they relate to the managment of speed and timing. Based on a case from the media industry, we identi...

    PRETIR is the acronym for Progress of Renewable Energy: Target Setting, Implementation and Realisation. The PRETIR project aims at developing a monitoring protocol, including a set of transparent indicators, through which monitoring of policy development with regard to renewable energy sources in the 15 European Union (EU) Member States can take place; i.e. the degree to which the national and European targets are translated to national action plans and policy instruments to realise the targeted implementation of renewable energy sources. By analysing the results of this monitoring process conclusions can be drawn on the likeliness of achieving the goals as set in the White Paper, the Directive on electricity from renewable energy sources, the draft Directive on biofuels and the Campaign for Take-Off. This report holds the results of the monitoring of renewable energy policies for the European Union. Chapters 2 and 3 start with a brief outline of the used definitions and monitoring methodology. A more detailed description of the methodology is available in the monitoring report, published separately. Chapter 4 provides an overview of the renewable energy policies in the EU Member States and is followed by chapters dealing with each of the distinguished renewable energy sources. Finally, chapter 11 holds the conclusions on the progress on implementation of renewable energy sources in the European Union.

    Europe's increasing demand for energy and its environmental preoccupations are creating a favourable environment for the development of renewable energy sources. This article stated that although many European countries have adopted voluntary policies since the 1990s to increase the use of renewable energy sources, they have not been developed in an equal or consistent manner. A table was included to show the consumption of renewable energies by country; the percentage of renewable energies in 1995 as compared to 2006; and the consumption of primary energy resources. Combined, Germany, Spain and Denmark produce 75 per cent of wind energy in Europe, while 75 per cent of Europe's hydroelectricity is produced in Norway, Sweden, France, Italy, Austria and Switzerland. Germany has also made significant contributions in developing biomass energy. The article emphasized that the development of renewable energy sources is limited by the fact that it cannot keep up with growing energy demands. In addition, renewable energies cannot yet replace all fossil fuel consumption in Europe because of the variation in development from one country to another. 1 ref., 2 tabs., 4 figs.

    TNB has a big role to play in Malaysia 's pursuit for modernization and socioeconomic progress. The most important task is to fulfill the nation's electricity demand in the most reliable manner and at the lowest cost possible with minimal of environmental impacts. TNB is committed to the development of renewable energy in this country. In fact, hydropower, which is a form of renewable energy, contributed significant proportion of the generating capacity in TNB. Research works on other forms of renewable energy like solar, wind, and biomass are actively being pursued by Tenaga Nasional Research and Development Sdn Bhd. As solar and wind energy systems are by nature emission-free, they provide a ready solution to the current air pollution and global warming problems. With the depletion of conventional non-renewable energy resources like oil, gas, and coal, the emergence of renewable energy as a reliable, alternative source of fuel would enhance security of energy supply in the long run. Because renewable energy is sourced locally, the country will benefit economically due to the cut on imported fuel and hence foreign exchange losses. For the policy makers, the most challenging task ahead is how to re-strategised the present policy on fuels in order to accommodate the contributions from other forms of renewable energy (other than hydro) without compromising on system reliability and cost to the customers. On DSM and Energy Efficiency programs pursued by TNB, the objective in is to discourage wasteful and expensive patterns of energy consumption. In that way, new electricity demand need not necessarily be met by new investment on new power stations. (Author)

    By the end of the 21 century, according to United National projections, the number of people on the earth is likely to have approximately doubled. How can a world of 10 to 12 billion people be provided with adequate supplies of energy, cleanly, safely and substantially? There is a growing consensus that renewable energy sources will be a very important part of the answer. The growing interest in 'renewables' has been prompted in part, by increasing concern over the pollution, resource depletion and possible climate change implications of our continuing use of conventional fossil and nuclear fuels. But recent technological developments have also improved the cost-effectiveness of many of the renewables, making their economic prospects look increasingly attractive. It describes the achievements and progress made in hydropower, biomass conversion, geothermal, solar thermal technology, wind energy conversion and the increasing usage of photovoltaics. It is evident that global warming is setting in and is going to change the climate as well as the terrain of many countries unless drastic measures are taken. The Kyoto meeting emphasised the importance of limiting CO 2 emissions and to abide by some form of agreement to reduce emissions. Present study concludes that renewable energy penetration into the energy market is much faster than was expected in recent years and by 2030, 15-20 percent of our prime energy will be met by renewable energy.

    2000-09-01

    New and renewable energies (hydro-power, wind-power, solar, biomass, biogas, geothermal and fuel cells) are progressively entering the industrialization phase (except for hydro-power which is already largely developed). Thus they are no more considered as solutions for utopian ecologists but have reached the status of alternative technologies. This study takes stock of the following questions: what are the applications of renewable energies, what is their stage of development and their potential with respect to fossil fuels, what are their perspectives of development, and what are the strategies developed by the actors of the sector? The main stakes of the renewable energy sector are: fulfilling the increasing power needs (in particular with the wind and solar power in isolated areas), improving the competitiveness (reduction of the investment costs), developing financial incentives (tax relief, financial helps, eco-taxes..), participating to the reduction of pollutant emissions. The renewable energy sector is progressively structuring and profits by the increasing implication of major energy actors, such as the oil companies. The behaviour and strategy of 14 major actors of the renewable energy sector is also analyzed. (J.S.)

    The last 10 years have witnessed a substantial progress in understanding the neural mechanisms for the renewal of the extinguished fear memory. Based on the theory of fear extinction, exposure therapy has been developed as a typical cognitive behavioral therapy for posttraumatic stress disorder. Although the fear memory can be extinguished by repeated presentation of conditioned stimulus without unconditioned stimulus, the fear memory is not erased and tends to relapse outside of extinction context, which is referred to as renewal. Therefore, the renewal is regarded as a great obstruction interfering with the effect of exposure therapy. In recent years, there has been a great deal of studies in understanding the neurobiological underpinnings of fear renewal. These offer a foundation upon which novel therapeutic interventions for the renewal may be built. This review focuses on behavioral, anatomical and electrophysiological studies that interpret roles of the hippocampus, prelimbic cortex and amygdala as well as the connections between them for the renewal of the extinguished fear. Additionally, this review suggests the possible pathways for the renewal: (1) the prelimbic cortex may integrate contextual information from hippocampal inputs and project to the basolateral amygdala to mediate the renewal of extinguished fear memory; the ventral hippocampus may innervate the activities of the basolateral amygdala or the central amygdala directly for the renewal. © 2017 IUBMB Life, 69(7):470-478, 2017. © 2017 International Union of Biochemistry and Molecular Biology.

    Full Text Available China is the most densely populated country in the world with high rate of economic growth resulting in higher demand for energy resources and in strive to guarantee stable supply of these resources. Chinese annual GDP growth in 2012 and 2013 was down to 7.7% comparing to 10% in 2000-2011 [7]. In 2012 and 2013 economic growth stumbled because of slowdown in manufacturing and exports, taking into account that Chinese government was eager to cut inflation and excessive investments in some segments of the market. Speaking about energy sector Chinese government is aimed at promotion of market-based pricing systems, activities for advanced energy efficiency and higher competition between energy companies, and increased investment in renewable energy resources. Considering renewables as one of many ways to diversify energy supplies, lower dependence on coal and improve environmental situation Chinese government actively supports and develops programs aimed at support of renewable energy industry in China. Chinese economic development is tightly attached to five-year plans. It seems important to mention the fact that main energy goals for current 12-th "five-year plan" are to achieve 15% renewables consumption and CO2 sequestration up to 40-45% by2020 in order to lower dependency on coal and improve environmental situation. As a result of Chinese state policy to develop renewables China achieved certain results in wind energy, helioenergetics, hydroenergetics and energy from waste recycling.

    The potential for renewable energy use in Canada is examined. It is pointed out that Canada can choose to begin to diversify its energy supply now, moving rapidly and smoothly towards an efficient energy society based on renewable energy sources; or, it can continue on its present course and face the possibility of being forced by necessity to make a later transition to renewable sources, probably with a great deal of economic and political disruption. The handbook begins with a discussion on major issues and options available. This second section deals with the technology, applications, and costs of direct solar energy utilization, solar thermal electricity generation, photovoltaic conversion, wind energy, biomass energy, tidal power, wave energy, ocean thermal energy, geothermal energy, heat pumps, and energy storage. Section three discusses how renewable energy might realistically supply Canada's energy requirements within a reasonable period of time. Some issues on how government, industry, and the individual may become involved to make this happen are suggested. A list of resource people and renewable energy businesses is provided in the last section. A recommended reading list and bibliography complete the handbook. (MCW)

    This paper focuses on the role of non-governmental organization (NGO) citizen groups in Ontario in the use and production of electricity. NGOs have the potential to act both directly on their own accord, and indirectly by pressuring government and others. Current demand for electricity is divided between industrial, commercial and residential users. Citizens have an important role to play in reducing energy demand. On the supply side, there is a revival of interest in renewable energy based on wind, photovoltaic and local-hydro technologies as a result of the escalating environmental and economic costs of coal and nuclear generation. However, citizen groups have greater interest and enthusiasm than technical expertise, creating a mismatch between technological solutions and human need or use of them. This paper discusses how this mismatch applies to renewable-energy technologies, many of which are not especially user-friendly, or accessible. While alternative technologies are increasingly welcomed by government, industry is developing a large and growing array of technological devices. In between this is the citizen, who, despite keen interest, can be overwhelmed by the complexity of the situation. This paper links the theoretical perspective to the real world with a discussion of the dynamics between people and renewable energy in citizen groups and makes particular reference to one group, Citizens for Renewable Energy, that has been making renewable energy technology more accessible to its members for over a decade

    In almost all geothermal projects worldwide, the rate of extraction of heat energy exceeds the pre-exploitation rate of heat flow from depth. For example, current production of geothermal heat from the Wairakei-Tauhara system exceeds the natural recharge of heat by a factor of 4.75. Thus, the current rate of heat extraction from Wairakei-Tauhara is not sustainable on a continuous basis, and the same statement applies to most other geothermal projects. Nevertheless, geothermal energy resources are renewable in the long-term because they would fully recover to their pre-exploitation state after an extended shut-down period. The present paper considers the general issue of the renewability of geothermal resources and uses computer modeling to investigate the renewability of the Wairakei-Tauhara system. In particular, modeling is used to simulate the recovery of Wairakei-Tauhara after it is shut down in 2053 after a hundred years of production. (author)

    The paper examines some of the factors which will influence the future mix of energy from fossil fuels and renewable sources in Australia. Aspects covered include: the present energy situation; impact of environmental issues; potential for renewable energy; motivators for change; and research and development. It is concluded that the future for fossil fuels and renewable energy is dependent on a number of complex factors, many of which are currently unknown. The key factor is economic viability and that will be influenced by a range of factors such as policies of the Australian and overseas governments in relation to pollution and environment protection (reflected in the cost of meeting such requirements), exploration and production costs (also influenced by government policies), availability of supply, rate of technological development and the size of export markets. 8 refs., 2 figs., 1 tab.

  13. Retributive and restorative justice.

    2008-10-01

    The emergence of restorative justice as an alternative model to Western, court-based criminal justice may have important implications for the psychology of justice. It is proposed that two different notions of justice affect responses to rule-breaking: restorative and retributive justice. Retributive justice essentially refers to the repair of justice through unilateral imposition of punishment, whereas restorative justice means the repair of justice through reaffirming a shared value-consensus in a bilateral process. Among the symbolic implications of transgressions, concerns about status and power are primarily related to retributive justice and concerns about shared values are primarily related to restorative justice. At the core of these processes, however, lies the parties' construal of their identity relation, specifically whether or not respondents perceive to share an identity with the offender. The specific case of intergroup transgressions is discussed, as are implications for future research on restoring a sense of justice after rule-breaking.

  14. Environmental Restoration Program Control Management System

    1992-01-01

    Environmental Restoration managers need to demonstrate that their programs are under control. Unlike most industrial programs, the public is heavily involved in Environmental Restoration activities. The public is demanding that the country prove that real progress is being made towards cleaning up the environment. A Program Control Management System can fill this need. It provides a structure for planning, work authorization, data accumulation, data analysis and change control. But it takes time to implement a control system and the public is losing its patience. This paper describes critical items essential to the quick development and implementation of a successful control system

    Energy Technology Data Exchange (ETDEWEB)

    Baker, B.; Cummings, J.

    1981-12-01

    The era of fossil fuel alternatives began with no clear definition or consensus on which energy supplies are alternatives or renewables. It also brought a technological search for diverse solutions, with solar getting the most adherents. Debate centered on how much solar and other renewables can realistically contribute to the total energy demand, what that contribution means in terms of barrels of oil and tons of coal, and how to attract the political and financial support necessary to develop new energy industries. The current status of renewable energy technologies underscores the critical juncture facing research because of inflation, budget cuts, the dismantlement of DOE, and a philosophical opposition to government participation. Some solar technologies can continue commercial development, but fusion is unique in its classification as a high-risk venture justifying government support. If research on renewable and synthetic energy sources is to progress, American industry must regroup and organize in support of technical, institutional, and social innovation. A timetable of development and commercialization for those technologies expected to be making a significant contribution by 2030 follows the article. (DCK)

    Many excavated quarries are subsequently used for waste disposal operations and frequently imported landfill provides the only means of restoring a former quarry to some beneficial afteruse. Concentrating solely on the final surface cover, this paper sets out some of the principles, which should be considered by those involved in landfill operations to ensure the long term success of restoration schemes. With the emphasis on restoration to agriculture, factors such as availability of cover materials and depths necessary are discussed in terms of requirements to support plant growth, protect clay capping layers and prevent damage to agricultural implements. Soil handling and appropriate after care management are considered. 4 refs.

    This document proposes a synthesis of debates organised within the frame the two sessions of a conference on renewable energies. The first session addressed the place given to renewable energies in the French energy mix. Contributions proposed an overview of industrial ambitions for the different sectors: wind energy (bidding projects leading to a French specialisation in offshore wing energy), photovoltaic (issue of re-structuration and development, and of technology selection), sea energy (French position, European situation), hydraulic (renewal of the sector through a renewal of hydroelectric concessions), biomass (level of exploitation), and biogas-bio-diesel-bio-ethanol (issue of economic viability). A second set of contributions addressed the financing cost of sector development (results of an inquiry commission on electricity cost, question of the efficiency of mechanisms of financial support of renewable energies, CSPE and purchase tariff, energy cost for the consumer with a sustainable energy mix, education opportunities for future jobs). The second session addressed the relationship between renewable energies and economic growth. A first set of contribution addressed the technological orientations (super grids, European cooperation, investment programs for transport and connection to renewable energies, returns on experience on smart grids), and a second set addressed the synergies between innovation and territories (partnership between research centres and local communities or private sector, supporting small and medium enterprises in their innovation and export efforts, implementation of local energy policy tools such as PCET and SRCAE, integration of protection of the environment in urban equipment and furniture, progress in energy renovation and struggle against fuel poverty)

    Full Text Available It is widely held that humankind's destructive tendencies when exploiting natural resources leads to irreparable harm to the environment. Yet, this thinking runs counter to evidence that many ecological systems damaged by severe natural environmental disturbances (e.g., hurricanes can restore themselves via processes of natural recovery. The emerging field of restoration ecology is capitalizing on the natural restorative tendencies of ecological systems to build a science of repairing the harm inflicted by humans on natural environment. Evidence for this, for example, comes from a new meta-analysis of 124 studies that synthesizes recovery of impacted wetlands worldwide. While it may take up to two human generations to see full recovery, there is promise, given human will, to restore many damaged wetlands worldwide.

    renewable energies. This is particularly important for the residential sector - but also for mobility - where the share of renewables is currently very low. We have shown that efficiency measures could potentially greatly conserve GHG emissions and fossil fuels. This implicates a prioritized use of state-of-the-art fossil technologies rather than expensive renewable energies. This would allow sufficient time for technological progress and cost reduction for renewable energies. This applies not only to the residential, but also to the mobility sector, where renewable energies are expensive and still in an early stage of development. The same is true with regard to the power sector, where, on the one hand a substitution of coal by natural gas could reduce GHG emissions. On the other hand, a temporal optimization of building up the different renewable energies could cut investment costs given a substantial decrease of costs in time. Currently, this could apply for offshore wind energy. In both cases, we were able to show the potential for considerable savings of GHG emissions, and, respectively, investment costs. Still, it is also always possible to reduce GHG emissions and costs by reducing the demand for power via efficiency measures. However, our results are subject to considerable uncertainty. As stated above, for the last ten years, the only constant in the rapidly changing energy sector has been the dynamic development of renewable energies. Empirical findings like Swanson's law may persist for many years. This assumption seems plausible, since renewable technologies are still not mature. Hence, the fundamental element of uncertainty might no longer be energy and climate politics, but rather technological progress. The evaluation of the importance of technological progress yields, however, to a fundamental question: what does ''Energiewende'' mean? There are two possible (extreme) points of view: on the one hand, one could argue that it is a

    Latvia is among those countries that do not have gas, coal and, for the time being, also oil resources of its own. The amount of power produced in Latvia does not meet the demand, consequently a part of the power has to be purchased from neighbouring countries. Firewood, peat and hydro resources are the only significant domestic energy resources. Massive decrease of energy consumption has been observed since Latvia regained independence. Domestic and renewable energy resources have been examined and estimated. There are already 13 modern boiler houses operating in Latvia with total installed capacity 45 MW that are fired with wood chips. Latvian companies are involved in the production of equipment. 7 small HPPs have been renewed with the installed capacity 1.85 MW. Wind plant in Ainazi has started its operation, where two modern wind turbines with the capacity of 0.6 MW each have been installed. Mechanism of tariff setting is aligned.

The amount of power produced in Latvia does not meet the demand, consequently a part of the power has to be purchased from neighbouring countries. Firewood, peat and hydro resources are the only significant domestic energy resources. Massive decrease of energy consumption has been observed since Latvia regained independence. Domestic and renewable energy resources have been examined and estimated. There are already 13 modern boiler houses operating in Latvia with total installed capacity 45 MW that are fired with wood chips. Latvian companies are involved in the production of equipment. 7 small HPPs have been renewed with the installed capacity 1.85 MW. Wind plant in Ainazi has started its operation, where two modern wind turbines with the capacity of 0.6 MW each have been installed. Mechanism of tariff setting is aligned. Favourable power energy purchasing prices are set for renewable energy sources and small cogeneration plants

  12. Cool energy. Renewal solutions to environmental problems

    This book begins with a chapter describing some of the economic and environmental consequences of America's fossil-fuel-based economy. It makes the case that, despite some progress in reducing pollution from fossil fuels, no lasting cure for the deteriorating environment - in particular, the looming threat of global warming - is possible without developing alternative fuel sources. That renewable energy can provide the bulk of the new supplies needed is the theme of the second chapter, which discusses the relative advantages of these resources compared to fossil fuels and nuclear power and evaluates their long-term potential. The bulk of the book considers five broad categories of renewable energy sources: solar, wind, biomass (plant matter), rivers and oceans, and geothermal. For each of these sources, the book describes its current application, discusses its costs, analyzes new technologies under development, and assesses its positive and negative environmental impacts. This book shows the vital role renewable sources can and should play in America's energy future. It cites studies indicating that, with the right policies, renewable energy could provide as much as half of America's energy within 40 years, and an even larger fraction down the road. Such a rapid shift from existing energy sources would be dramatic but not unprecedented. In 1920, coal supplied 70% of US energy, but within 40 years its share had dropped to just 20% as oil and natural gas use increased. Sooner or later, oil and natural gas will also fade in importance. The real question is when. This book makes the case that the time to move decisively toward a renewable energy economy has arrived

  13. The observational approach in environmental restoration

    The US Department of Energy (DOE) has committed to completing environmental restoration of its facilities within the next 28 years (DOE 1990b). In order to achieve this, DOE must ensure that its restoration activities are both effective and efficient. A key aspect of fulfilling this commitment is the recognition and management of uncertainty that is inherent in waste-site clean-up actions. The DOE Office of Environmental Restoration (DOE-ER) requested Pacific Northwest Laboratory (PNL) to investigate the applicability and implementation of what is known as the ''observational approach'' to better address these needs. PNL's initial investigation resulted in the positive conclusion that the observational approach had potential benefit to DOE during environmental restoration. In a follow-on effort, PNL supported by CH2M HILL, has been providing guidance to DOE field-offices on observational approach fundamentals, implementation, and application to waste-site remediation. This paper outlines the fundamentals of the observational approach and discusses the progress in integrating the observational approach in DOE's environmental restoration efforts. 9 refs., 2 figs

    This viewpoint reviews renewable energy development in 14 markets that differ in market structure (restructured vs. not restructured), use of feed-in-tariff (FIT) (yes vs. no), transmission planning (anticipatory vs. reactive), and transmission interconnection cost allocated to a renewable generator (high vs. low). We find that market restructuring is not a primary driver of renewable energy development. Renewable generation has the highest percent of total installed capacity in markets that use a FIT, employ anticipatory transmission planning, and have loads or end-users paying for most, if not all, of the transmission interconnection costs. In contrast, renewable developers have been less successful in markets that do not use a FIT, employ reactive transmission planning, and have generators paying for most, if not all, of the transmission interconnection costs. While these policies can lead to higher penetration of renewable energy in the short run, their high cost to ratepayers can threaten the economic sustainability of renewable energy in the long-run. - Highlights: → Market structure seems to have little effect on renewable energy development. → Renewable energy development is more successful in markets that use a FIT. → Anticipatory transmission planning aids renewable energy development. → Low interconnection costs for developers also aids renewable energy development.

    Utilization of renewable energy sources and the application of environmentally sound energy technologies are essential to sustainable development and will help to secure the quality of living and the well-being of the future generations. Turkey presently has considerable renewable energy sources. The most important renewable sources are hydropower, wind, solar, geothermal, and biomass. The use of renewable energy as a topic to study energy and its forms permits a novel way to motivate students, particularly those who energy topics taking conscience with the environment. This paper presents the analysis and classification of renewable energy sources and how to find out their origin and a way to motivate students in energy topics related to renewable sources and also, the development of didactic competencies in special blended learning arrangements for educationalists, trainers and lecturers in adult education in the field of renewable energies in Turkey.

    Public policy and funding are basically different, but both are needed to develop the renewable energy market. Public policy creates incentives, but also obligations. The setting up of a 'repurchase rate' also called a 'feed-in tariff' or 'clean energy cash back scheme' obliges electric power companies to buy back energy of renewable origin at a fixed, guaranteed rate. The extra-cost generated, although usually low, is passed on to all customers and does not cost the State anything. Funding is characterized by its source, the manner in which it is obtained and who supplies it, whether it be banks, mutual funds, development agencies, electric power companies, local governments or the consumers themselves. Repurchasing yields regular cash flows over a given period at a lower risk and allows banks to provide funding. This is one of the reasons for its success. This solution is also very popular with political leaders because it does not weigh down public funding. Both these reasons explain why repurchasing is so appreciated in Europe and in a growing number of countries, more than seventy having adopted it in 2010. In addition, it is regularly discounted in relation to technological breakthroughs and lower costs. As is the case in Europe, the problem lies in maintaining an acceptable rate while avoiding excessive project profitability. In Europe, for instance, the number of renewable energy projects is such that consumers are starting to complain about seeing their electricity rates rise because of the famous feed-in tariff, even though the cost of renewable energies continues to drop on a regular basis. The United States and a few other countries, including China, prefer the quota system, or RPS (Renewable Portfolio Standards), which requires electric power companies to generate a minimal share of electric power by a renewable energy source. These companies consequently invest in renewable energy projects or purchase this energy from other suppliers. Like the

    A long-lasting immunological suppression action seems to be produced by total lymphoid irradiation; some authors emphasize the favorable effect of this treatment on chronic progressive multiple sclerosis. In order to evaluate the actual role of TLI, 6 patients affected with chronic progressive multiple sclerosis were submitted to TLI with shaped and personalized fields at the Istituto del Radio, University of Brescia, Italy. The total dose delivered was 19.8 Gy in 4 weeks, 1.8 Gy/day, 5d/w; a week elapsed between the first and the second irradiation course. Disability according to Kurtzke scale was evaluated, together with blood lymphocyte count and irradiation side-effects, over a mean follow-up period of 20.8 months (range: 13-24). Our findings indicate that: a) disease progression was not markedly reduced by TLI; b) steroid hormones responsivity was restored after irradiation, and c) side-effects were mild and tolerable

    In vertebrate retina, histogenesis occurs over an extended period. To sustain the temporal generation of diverse cell types, retinal progenitor cells (RPCs) must self-renew. However, self-renewal and regulation of RPCs remain poorly understood. Here, we demonstrate that cell-extrinsic factors coordinate with the epigenetic regulator high-mobility group AT-hook 2 (Hmga2) to regulate self-renewal of late retinal progenitor cells (RPCs). We observed that a small subset of RPCs was capable of clonal propagation and retained multipotentiality of parents in the presence of endothelial cells (ECs), known self-renewal regulators in various stem cell niches. The self-renewing effects, also observed in vivo, involve multiple intercellular signaling pathways, engaging Hmga2. As progenitors exhaust during retinal development, expression of Hmga2 progressively decreases. Analyses of Hmga2-expression perturbation, in vitro and in vivo, revealed that Hmga2 functionally helps to mediate cell-extrinsic influences on late-retinal progenitor self-renewal. Our results provide a framework for integrating the diverse intercellular influences elicited by epigenetic regulators for self-renewal in a dynamic stem cell niche: the developing vertebrate retina. © 2014.

    Renewable energy technologies increase their hold across developing and emerging economies throughout the year The year 2016 saw several developments and ongoing trends that all have a bearing on renewable energy, including the continuation of comparatively low global fossil fuel prices; dramatic price declines of several renewable energy technologies; and a continued increase in attention to energy storage. For the third consecutive year, global energy-related carbon dioxide emissions from fossil fuels and industry were nearly flat in 2016, due largely to declining coal use worldwide but also due to improvements in energy efficiency and to increasing use of renewable energy. As of 2015, renewable energy provided an estimated 19.3% of global final energy consumption, and growth in capacity and production continued in 2016. The power sector experienced the greatest increases in renewable energy capacity in 2016, whereas the growth of renewables in the heating and cooling and transport sectors was comparatively slow. Most new renewable energy capacity is installed in developing countries, and largely in China, the single largest developer of renewable power and heat over the past eight years. In 2016, renewable energy spread to a growing number of developing and emerging economies, some of which have become important markets. For the more than 1 billion people without access to electricity, distributed renewable energy projects, especially those in rural areas far from the centralised grid, offer important and often cost-effective options to provide such access. The renewable energy sector employed 9.8 million people in 2016, an increase of 1.1% over 2015. By technology, solar PV and biofuels provided the largest numbers of jobs. Employment shifted further towards Asia, which accounted for 62% of all renewable energy jobs (not including large-scale hydropower), led by China. The development of community renewable energy projects continued in 2016, but the pace of

    Long-term changes and fluctuations in river flow, water properties, tides, and sediment transport in the Columbia River and its estuary have had a profound effect on Columbia River salmonids and their habitat. Understanding the river-flow, temperature, tidal, and sediment-supply regimes of the Lower Columbia River (LCR) and how they interact with habitat is, therefore, critical to development of system management and restoration strategies. It is also useful to separate management and climate impacts on hydrologic properties and habitat. This contract, part of a larger project led by the National Oceanic and Atmospheric Administration (NOAA), consists of three work elements, one with five tasks. The first work element relates to reconstruction of historic conditions in a broad sense. The second and third elements consist, respectively, of participation in project-wide integration efforts, and reporting. This report focuses on the five tasks within the historic reconstruction work element. It in part satisfies the reporting requirement, and it forms the basis for our participation in the project integration effort. The first task consists of several topics related to historic changes in river stage and tide. Within this task, the chart datum levels of 14 historic bathymetric surveys completed before definition of Columbia River Datum (CRD) were related to CRD, to enable analysis of these surveys by other project scientists. We have also modeled tidal datums and properties (lower low water or LLW, higher high water or HHW, mean water level or MWL, and greater diurnal tidal range or GDTR) as a function of river flow and tidal range at Astoria. These calculations have been carried for 10 year intervals (1940-date) for 21 stations, though most stations have data for only a few time intervals. Longer-term analyses involve the records at Astoria (1925-date) and Vancouver (1902-date). Water levels for any given river flow have decreased substantially (0.3-1.8 m, depending

    The hematopoietically expressed homeobox transcription factor (Hhex) is important for the maturation of definitive hematopoietic progenitors and B-cells during development. We have recently shown that in adult hematopoiesis, Hhex is dispensable for maintenance of hematopoietic stem cells (HSCs) and myeloid lineages but essential for the commitment of common lymphoid progenitors (CLPs) to lymphoid lineages. Here, we show that during serial bone marrow transplantation, Hhex-deleted HSCs are progressively lost, revealing an intrinsic defect in HSC self-renewal. Moreover, Hhex-deleted mice show markedly impaired hematopoietic recovery following myeloablation, due to a failure of progenitor expansion. In vitro, Hhex-null blast colonies were incapable of replating, implying a specific requirement for Hhex in immature progenitors. Transcriptome analysis of Hhex-null Lin - Sca + Kit + cells showed that Hhex deletion leads to derepression of polycomb repressive complex 2 (PRC2) and PRC1 target genes, including the Cdkn2a locus encoding the tumor suppressors p16 Ink 4 a and p19 Arf . Indeed, loss of Cdkn2a restored the capacity of Hhex-null blast colonies to generate myeloid progenitors in vitro, as well as hematopoietic reconstitution following myeloablation in vivo. Thus, HSCs require Hhex to promote PRC2-mediated Cdkn2a repression to enable continued self-renewal and response to hematopoietic stress. Stem Cells 2017;35:1948-1957. © 2017 AlphaMed Press.

    We are building a multidisciplinary research program linking researchers in agriculture, business, earth science, engineering, humanities and social science. Our goal is to match renewable energy supply and reformed energy demands. The program will be focused on (i) understanding and modifying energy demand, (ii) design and implementation of diverse renewable energy networks. Geomatics technology will be used to map existing energy and waste flows on a neighbourhood, municipal, and regional level. Optimal sites and combinations of sites for solar and wind electrical generation (ridges, rooftops, valley walls) will be identified. Geomatics based site and grid analyses will identify best locations for energy production based on efficient production and connectivity to regional grids and transportation. Design of networks for utilization of waste streams of heat, water, animal and human waste for energy production will be investigated. Agriculture, cities and industry produce many waste streams that are not well utilized. Therefore, establishing a renewable energy resource mapping and planning program for electrical generation, waste heat and energy recovery, biomass collection, and biochar, biodiesel and syngas production is critical to regional energy optimization. Electrical storage and demand management are two priorities that will be investigated. Regional scale cooperatives may use electric vehicle batteries and innovations such as pump storage and concentrated solar molten salt heat storage for steam turbine electrical generation. Energy demand management is poorly explored in Canada and elsewhere - our homes and businesses operate on an unrestricted demand. Simple monitoring and energy demand-ranking software can easily reduce peaks demands and move lower ranked uses to non-peak periods, thereby reducing the grid size needed to meet peak demands. Peak demand strains the current energy grid capacity and often requires demand balancing projects and

These are: the fuel deposits becoming exhausted, hazard to environment (especially carbon dioxide) and accessibility of these sources for under-developed countries. An interrelation is shown between these sources and the energy circulations connected with atmosphere and ocean systems. The chief ones from among them that are being used now are discussed, i.e. solar radiation, wind, water waves energy, tides, geothermal heat, and the like. Problems of conversion of the forms of these kinds of energy are also given a mention. (author)

    The expansion of electricity generation from renewable sources in Germany is promoted by the Erneuerbare-Energien-Gesetz (EEG), which was last amended in June 2008. In a review of the EEG the political parameters, the progress achieved, and the impacts of the Act itself are set out. This Progress Report addresses cross-sectoral aspects, notably CO 2 emissions reduction, job creation, investment and turnover in the renewables industry, and that industry's prospects for the future. Trends in the individual renewables sectors are described and policy recommendations formulated, as appropriate, on this basis. The policy recommendations have been incorporated into the new EEG from 6 June 2008. The overarching goal of the new EEG is to achieve a renewables share of at least 30% in Germany's electricity consumption in 2020. This underlines the need for radical modernisation of the energy system as a whole. This article presents an overview of the content of the Progress Report and supplements it with current statistical data and research findings contained in other publications from the Federal Ministry for the Environment (BMU). It also highlights the points on which the new EEG diverges from the policy recommendations contained in the Progress Report.

    from conventional sources (including gas, coal, oil, and nuclear). Renewable energy industries boomed during most of 2008. Global solar PV production increased by 90 percent to 6.9 GW in 2008. China usurped Japan to become the new world leader in PV cell production and also experienced huge growth in its wind power industry, with many new companies producing wind turbines and components. Globally, the wind industry continued to push turbine sizes higher, with models of 3 MW or larger becoming more widespread. The concentrating solar power (CSP) industry saw many entrants and new manufacturing facilities. The ethanol and bio-diesel industries similarly expanded, particularly in North America and Latin America, and the cellulosic ethanol industry was in the process of booming, with 300 million liters per year of capacity under construction. Although the clean energy sector initially weathered the financial crisis in late 2008 better than many other sectors, renewable investment did experience a downturn after September 2008. However, projects continued to progress and many economic stimulus bills included components for supporting renewable energy. At the same time, development assistance for renewables in developing countries expanded greatly, reaching about $2 billion in 2008. By early 2009, policy targets existed in at least 73 countries, and at least 64 countries had policies to promote renewable power generation, including 45 countries and 18 states/provinces/territories with feed-in tariffs (many of these recently updated). The number of countries/states/ provinces with renewable portfolio standards increased to 49. Policy targets for renewable energy were added, supplemented, revised, or clarified in a large number of countries in 2008. Many forms of policy support for renewables were added, supplemented, or extended in a number of countries during 2008. For example, new solar PV subsidy programs were adopted in Australia, China, Japan, Luxembourg, the Netherlands

    The economic contribution of the CEPA (Canadian Energy Pipeline Association) member companies to Canada's trade balance was discussed. CEPA member companies transport 95 per cent of the crude oil and natural gas produced in Canada to domestic and export markets. This represents a total of 5.6 Tcf of gas annually. Half of Canada's natural gas and oil production is exported to U.S. markets. All of these exports are transported by pipeline. CEPA member companies operate 90,000 km of pipeline from British Columbia to Quebec. Expansions are needed as a result of a significant increase in demand for natural gas and crude oil since 1990. Several issues exist for regulatory renewal. They include the need to create a level playing field, the overseeing of tolls and contract renewal terms, changing risk/reward trade-offs, the right to confidentiality of information and price discovery mechanism. The drivers for regulatory reform at Westcoast Energy are the need for pricing flexibility, customers desire for toll certainty, decontracting and opposition to rolled-in expansions for gathering and processing. An overview of Westcoast Energy's negotiated toll settlement, its implications, and the components of Westcoast Energy's 'light handed regulation' (LHR) was presented

    The renewable energy sector is evolving, and today, renewable energy has become a viable alternative for many facilities. Because this sector is in its infancy stage, lack of experience has resulted in failing solar projects. This project involves the design and implementation of a functioning web application that streamlines and automates the planning, risk assessment and financing of a solar development project. The three key stakeholders, the host facility, solar installer and financier are seamlessly integrated into a single marketplace. By designing a project development workflow, projects are vetted early on and terminated if deemed infeasible, saving time and resources. By risk assessing the project using the proposed scoring model, one can inherit more confident investors. The project scoring model also serves as a debt rating system, where investors can measure the risk/rewards. The platform will also serve as a communication medium between the three stakeholders. Besides storing documents like engineering drawings, permits, etc., the platform auto-generates all necessary transactional documents, legal documents and agreements among the three stakeholders.

    Two renewable electricity bills have been proposed in Congress since 2005 in Mexico. The first one was rejected by the Senate and the second one was approved by both the House of Representatives and the Senate in October 2008. Our objective is to explain the nature of both bills and to analyze each of them bearing in mind the Mexican electricity sector management scheme. In the Mexican electricity sector single-buyer scheme, the state-owned companies (Comision Federal de Electricidad and Luz y Fuerza del Centro) are responsible of the public services and the private sector generates electricity under six modalities: self-supply, cogeneration, independent production, small production, export, and import, which are not considered a public service. This scheme has caused controversies related to the constitutionality of the 1992 Power Public Services Law that allowed this scheme to be implemented. Both bills, the rejected one and the approved one, were formulated and based on that controversial law and their objectives are linked precisely more to the controversial issues than to the promotion of renewable electricity technologies; consequently, the gap among environmental, economic and social issues related with sustainability notion is wider.

  1. Renewable Energy in Reunion: Potentials and Outlook

    International Nuclear Information System (INIS)

    Baddour, Julien; Percebois, Jacques

    2011-01-01

    Renewable, environmentally friendly and evenly distributed across the globe, renewable energy (RES for Renewable Energy Resources) is an excellent means of taking up the global energy challenge, i.e. enabling developing countries in the south to make progress without harming the environment. Since it is particularly well suited to an island territory's character and local needs, RE is also an excellent tool that could enable France's overseas Departments and Territories to reduce their energy dependence, preserve their environment and ensure their sustainable development. In Reunion, RES benefit from marked political support and from a very favourable financial and institutional environment, which has allowed the Reunion region to become a national pioneer in the realm of thermal energy and photovoltaics. Nonetheless, RES are not a panacea as they are subject to a number of flaws. It is currently expensive and uncompetitive, intermittent and insufficiently powerful, and not always available to keep up with demand. This explains why RES cannot aspire to be a complete substitute for fossil fuels. The two energy systems complement one another to meet the region's total energy needs. This article also highlights the negative consequences of the support measures for RES (inflated costs and negative prices on the electricity markets) and underscores the need for a complementary energy policy in pricing electricity, as well as effecting energy savings, which must remain our priority.

  2. Understanding China's renewable energy technology exports

    2013-01-01

    China became a major player in renewable energy (RE) technology during the 2000s. Chinese solar PV cell and module makers quickly dominated global sales in that industry, while the country's wind turbine producers became poised for significant exports after capturing their rapidly growing home market. In countries like the US, Chinese RE technology strength has been met with claims of excessive governmental support of exports. This study examines to what extent Chinese firms' solar PV and wind technology successes have been enabled by policy supports, and whether those policies appear to have been driven by broader goals versus RE export promotion per se. The evidence suggests that governmental policy toward both wind and solar originated in a push for export-competitive Chinese companies. But the specifics differed substantially due to the particular requirements of building technological capabilities in each: export readiness necessitated substantial support for domestic installation of wind but not solar PV power. The findings also suggest that as the decade of the 2000s progressed, environmental goals played an increasing role alongside export promotion in motivating and shaping Chinese RE technology policies. - Highlights: ► Export policy in the rise of Chinese renewable energy technologies is studied. ► Policy supported wind turbine firms' capabilities via domestic uptake, not exports. ► Pre-2009 solar module exports enjoyed, but did not depend on, export subsidies. ► Renewables development also fit wider technology and environmental policy goals.

    In 2007, more than $100 billion was invested in new renewable energy capacity, manufacturing plants, and research and development-a true global milestone. Yet perceptions lag behind the reality of renewable energy because change has been so rapid in recent years. This report captures that reality and provides an overview of the status of renewable energy worldwide in 2007. The report covers trends in markets, investments, industries, policies, and rural (off-grid) renewable energy. (By design, the report does not provide analysis, discuss current issues, or forecast the future.) Many of the trends reflect increasing significance relative to conventional energy

  6. Sustainable Elastomers from Renewable Biomass.

    2017-07-18

    Sustainable elastomers have undergone explosive growth in recent years, partly due to the resurgence of biobased materials prepared from renewable natural resources. However, mounting challenges still prevail: How can the chemical compositions and macromolecular architectures of sustainable polymers be controlled and broadened? How can their processability and recyclability be enabled? How can they compete with petroleum-based counterparts in both cost and performance? Molecular-biomass-derived polymers, such as polymyrcene, polymenthide, and poly(ε-decalactone), have been employed for constructing thermoplastic elastomers (TPEs). Plant oils are widely used for fabricating thermoset elastomers. We use abundant biomass, such as plant oils, cellulose, rosin acids, and lignin, to develop elastomers covering a wide range of structure-property relationships in the hope of delivering better performance. In this Account, recent progress in preparing monomers and TPEs from biomass is first reviewed. ABA triblock copolymer TPEs were obtained with a soft middle block containing a soybean-oil-based monomer and hard outer blocks containing styrene. In addition, a combination of biobased monomers from rosin acids and soybean oil was formulated to prepare triblock copolymer TPEs. Together with the above-mentioned approaches based on block copolymers, multigraft copolymers with a soft backbone and rigid side chains are recognized as the first-generation and second-generation TPEs, respectively. It has been recently demonstrated that multigraft copolymers with a rigid backbone and elastic side chains can also be used as a novel architecture of TPEs. Natural polymers, such as cellulose and lignin, are utilized as a stiff, macromolecular backbone. Cellulose/lignin graft copolymers with side chains containing a copolymer of methyl methacrylate and butyl acrylate exhibited excellent elastic properties. Cellulose graft copolymers with biomass-derived polymers as side chains were

  7. The share of renewable energy in the EU. Country Profiles. Overview of Renewable Energy Sources in the Enlarged European Union

    2004-01-01

    The promotion of renewable energy has an important role to play in addressing the growing dependence on energy imports in Europe and in tackling climate change. Since 1997, the Union has been working towards the ambitious target of a 12% share of renewable energy in gross inland consumption by 2010. In 1997, the share of renewable energy was 5.4%; by 2001 it had reached 6%. This Staff Working Document gives an overview of the different situations of renewable energy sources in the European Union. It includes part of the formal report that the Commission is required to make under Article 3 of Directive 2001/77/EC on electricity from renewable energy sources, and it completes the overall picture with information at a country level on the heat produced from renewable energies and biofuels in the transport sector. This Staff Working Document complements the Communication on 'The share of Renewable Energy sources in the EU'. Data is based on different sources. Firstly, on the reports from Member States on national progress in achieving the targets on electricity from renewable energy sources. Secondly, on a study launched by the Commission on the evolution of renewable energy sources. And thirdly, on a variety of sources like the European Barometer of renewable energies, data from the industry, etc. With the enlargement of the European Union, the new Member States are required to adopt the RES-E Directive (renewable energy sources for electricity) by 1 May 2004. In the accession treaty, national indicative targets are set and the overall renewable electricity target for the enlarged Union will therefore be 21% of gross electricity consumption by 2010. The Commission has the legal obligation to report on the degree of achievement of new Member States' targets by 2006. Although it is too early to assess RES-policy in the new Member States due to very recently adopted regulations, this document also includes national information on the States now joining the European Union

    Renewable energy is now a mainstream concern among businesses and governments across the world, and could be considered a characteristic preoccupation of our time. It is interesting to note that many of the energy technologies currently being developed date back to very different eras, and even predate the industrial revolution. The fuel cell was first invented as long ago as 1838 by the Swiss--German chemist Christian Friedrich Schönbein [1], and the idea of harnessing solar power dates back to ancient Greece [2]. The enduring fascination with new means of harnessing energy is no doubt linked to man's innate delight in expending it, whether it be to satisfy the drive of curiosity, or from a hunger for entertainment, or to power automated labour-saving devices. But this must be galvanized by the sustained ability to improve device performance, unearthing original science, and asking new questions, for example regarding the durability of photovoltaic devices [3]. As in so many fields, advances in hydrogen storage technology for fuel cells have benefited significantly from nanotechnology. The idea is that the kinetics of hydrogen uptake and release may be reduced by decreasing the particle size. An understanding of how effective this may be has been hampered by limited knowledge of the way the thermodynamics are affected by atom or molecule cluster size. Detailed calculations of individual atoms in clusters are limited by computational resources as to the number of atoms that can studied, and other innovative approaches that deal with force fields derived by extrapolating the difference between the properties of clusters and bulk matter require labour-intensive modifications when extending such studies to new materials. In [4], researchers in the US use an alternative approach, considering the nanoparticle as having the same crystal structure as the bulk but relaxing the few layers of atoms near the surface.

    Full Text Available Ecological restoration and the mainstreaming of the concept of ecosystem services will be critical if global society is to move toward sustainability. Conference of the Parties 21 (COP21 of the United Nations Framework Convention on Climate Change and COP12 of the Convention on Biological Diversity should help foster support for vastly increased investment in the better management and restoration of natural capital. Large-scale restoration demonstrably improves ecological functioning to sustain both biodiversity and human well-being. However, much progress is needed to improve the effectiveness and cost efficiency of any restoration. The ecosystem services concept provides a framework for identifying the types of restorative interventions needed to target different forms and degrees of degradation, and achieve goals related to both ecosystem health and delivery of services to people. Moreover, it can strengthen the argument for, and planning of, large-scale restoration and conservation of natural capital. We use case studies from four continents to help demonstrate how the interconnection between ecological restoration and the ecosystem services concept is being utilized in land-use planning and enlightened ecosystem management. We offer ways in which this relationship can be better understood and communicated to support the scaling up of restoration activities to the landscape and regional scales across the full spectrum of land uses and ecosystem types.

    Acrylonitrile (ACN) is a petroleum-derived compound used in resins, polymers, acrylics, and carbon fiber. We present a process for renewable ACN production using 3-hydroxypropionic acid (3-HP), which can be produced microbially from sugars. The process achieves ACN molar yields exceeding 90% from ethyl 3-hydroxypropanoate (ethyl 3-HP) via dehydration and nitrilation with ammonia over an inexpensive titanium dioxide solid acid catalyst. We further describe an integrated process modeled at scale that is based on this chemistry and achieves near-quantitative ACN yields (98 +/- 2%) from ethyl acrylate. This endothermic approach eliminates runaway reaction hazards and achieves higher yields than the standard propylene ammoxidation process. Avoidance of hydrogen cyanide as a by-product also improves process safety and mitigates product handling requirements.

    In 1987 an American-style fridge freezer would use about 950 kWh of electricity and cost about 150 (£80) a year to run. Two decades on, a comparable appliance uses half the electricity and costs less than half as much to run. In 1975 there were about 3780 000 cars on the streets of Los Angeles, whereas today there are more than 5200 000 - yet air-pollution levels have fallen by half and an increasing number of those vehicles are hybrids or rely on renewable fuels like bio-diesel. Last year, half a million homes in Southern California were receiving direct solar power, either from solar electricity plants or from rooftop photovoltaic panels.

    2016-03-01

    Full Text Available Energy production based on fossil fuel reserves is largely responsible for carbon emissions, and hence global warming. The planet needs concerted action to reduce fossil fuel usage and to implement carbon mitigation measures. Ocean energy has huge potential, but there are major interdisciplinary problems to be overcome regarding technology, cost reduction, investment, environmental impact, governance, and so forth. This article briefly reviews ocean energy production from offshore wind, tidal stream, ocean current, tidal range, wave, thermal, salinity gradients, and biomass sources. Future areas of research and development are outlined that could make exploitation of the marine renewable energy (MRE seascape a viable proposition; these areas include energy storage, advanced materials, robotics, and informatics. The article concludes with a sustainability perspective on the MRE seascape encompassing ethics, legislation, the regulatory environment, governance and consenting, economic, social, and environmental constraints. A new generation of engineers is needed with the ingenuity and spirit of adventure to meet the global challenge posed by MRE.

    Full Text Available The article consists of two parts. The first deals with the theoretical framework of urban rehabilitation. Literature provides the basis for a conclusion, which is that the key issue in rehabilitation projects is legitimate negotiation of various interests between participating individuals and institutions. In the second part this presentation and analyses of events that took place at the urban design workshop organised within the framework of the research project Renewal of housing estates in Ljubljana, provide experiential confirmation of the starting thesis. We established that the directly involved residents were willing to actively participate in rehabilitation procedures, however the process is never triggered, because of insufficient capacities in institutional frameworks. In conclusion several real proposals are shown, namely, how to surmount obstacles in urban rehabilitation and especially in larger housing estates built after World War 2.

    Grazi, Laure; Souletie, Arthur

    2016-03-01

    Renewable energy sources (RES) are low-carbon energies available right within our borders, and as such can be of great value in addressing the challenges of climate change and energy security. In 2014, renewable energies accounted for 14.6% of France's gross final energy consumption. The French Energy Transition Act for Green Growth sets renewables targets of 23% and 32% as a share of gross final energy consumption by 2020 and 2030, respectively. However, renewable energies are still more costly than conventional energies. A significant share of this additional cost is borne by energy consumers, particularly in the form of energy taxation and biofuels blending obligations. Public aid is also provided to support heat production from renewable energy sources (RES-H). The two most significant aids available today are the Energy Transition Tax Credit (CITE) and the Heat Fund. Comparing the various types of renewable energies shows sharp disparities in terms of the cost of avoiding one tonne of CO 2 , which ranges from euros 59 to more than euros 500 for electricity production it follows that the cost of the energy transition is likely to vary significantly depending on which renewable energy sources are pushed to the fore. The combustion of biomass for heat production appears to offer an economically efficient way to reduce CO 2 emissions. Of the various renewable technologies available for the production of electricity (with the exception of hydropower, which was excluded from the scope of this study), onshore wind power is the least costly

    The County of Somerset, New Jersey, through the Somerset County Improvement Authority (SCIA), applied Federal funding through the U.S. Department of Energy to will apply project funds to buy-down the capital costs of equipment associated with the installation of solar photovoltaic (PV) systems at two sites owned by the County. This Renewable Energy Initiative allows the County to take advantage of clean renewable energy, without any adverse debt impacts, and at a price that results in operating budget savings beyond what is presently available in the marketplace. This project addressed the objectives of the Office of Energy Efficiency and Renewable Energy by making the acquisition of renewable energy more affordable for the County, thereby, encouraging other counties and local units to develop similar programs and increase the deployment of solar energy technologies. The two sites that were funded by the DOE grant are part of a much larger, ambitious, and unique renewable energy project, described in the next section.

    Flomenbom, Ophir

    2010-01-01

    Renewal-anomalous-heterogeneous files are solved. A simple file is made of Brownian hard spheres that diffuse stochastically in an effective 1D channel. Generally, Brownian files are heterogeneous: the spheres' diffusion coefficients are distributed and the initial spheres' density is non-uniform. In renewal-anomalous files, the distribution of waiting times for individual jumps is not exponential as in Brownian files, yet obeys: ψ α (t)∼t -1-α , 0 2 >, obeys, 2 >∼ 2 > nrml α , where 2 > nrml is the MSD in the corresponding Brownian file. This scaling is an outcome of an exact relation (derived here) connecting probability density functions of Brownian files and renewal-anomalous files. It is also shown that non-renewal-anomalous files are slower than the corresponding renewal ones.

  12. Modeling renewable energy company risk

    International Nuclear Information System (INIS)

    Sadorsky, Perry

    2012-01-01

    The renewable energy sector is one of the fastest growing components of the energy industry and along with this increased demand for renewable energy there has been an increase in investing and financing activities. The tradeoff between risk and return in the renewable energy sector is, however, precarious. Renewable energy companies are often among the riskiest types of companies to invest in and for this reason it is necessary to have a good understanding of the risk factors. This paper uses a variable beta model to investigate the determinants of renewable energy company risk. The empirical results show that company sales growth has a negative impact on company risk while oil price increases have a positive impact on company risk. When oil price returns are positive and moderate, increases in sales growth can offset the impact of oil price returns and this leads to lower systematic risk.

  13. Renewable energies for power generation

    2009-01-01

    Power generation from renewable energy sources is different from power generation from classical energies (nuclear, thermal..). Therefore, the integration into the grid of the electricity supplied by renewable sources requires a deep thinking. The reason is that these power sources are controlled by variable elements, like wind, water and sun, which condition production. This book deals with the following aspects in detail: characteristics of classical and intermittent generators; grid balancing between supply and demand; conversion methods of renewable energies into electricity; power systems; privatizing of power generation and birth of new markets, in particular the 'green' power market; development of renewable energies thanks to technical advances. It gives a comprehensive overview of the present day available renewable energy sources for power generation. (J.S.)

    Morris, Douglas R; DeYoung, Nathaniel J

    2014-01-01

    While the United States Supreme Court's Jackson v. Indiana decision and most state statutes mandate determinations of incompetent defendants' restoration probabilities, courts and forensic clinicians continue to lack empirical evidence to guide these determinations and do not yet have a consensus regarding whether and under what circumstances incompetent defendants are restorable. The evidence base concerning the restoration likelihood of those defendants who fail initial restoration efforts is even further diminished and has largely gone unstudied. In this study, we examined the disposition of a cohort of defendants who underwent long-term competence restoration efforts (greater than six months) and identified factors related to whether these defendants were able to attain restoration and adjudicative success. Approximately two-thirds (n = 52) of the 81 individuals undergoing extended restoration efforts were eventually deemed restored to competence. Lengths of hospitalization until successful restoration are presented with implications for the reasonable length of time that restoration efforts should persist. Older individuals were less likely to be restored and successfully adjudicated, and individuals with more severe charges and greater factual legal understanding were more likely to be restored and adjudicated. The significance of these findings for courts and forensic clinicians is discussed.

    The choice of the most appropriate restoration for anterior teeth is often a difficult decision. Numerous clinical and technical factors play an important role in selecting the treatment option that best suits the patient and the restorative team. Experienced clinicians have developed decision processes that are often more complex than may seem. Less experienced professionals may find difficulties making treatment decisions because of the widely varied restorative materials available and often numerous similar products offered by different manufacturers. The authors reviewed available evidence and integrated their clinical experience to select relevant factors that could provide a logical and practical guideline for restorative decisions in anterior teeth. The presented concept of restorative volume is based on structural, optical, and periodontal factors. Each of these factors will influence the short- and long-term behavior of restorations in terms of esthetics, biology, and function. Despite the marked evolution of esthetic restorative techniques and materials, significant limitations still exist, which should be addressed by researchers. The presented guidelines must be regarded as a mere orientation for risk analysis. A comprehensive individual approach should always be the core of restorative esthetic treatments. The complex decision process for anterior esthetic restorations can be clarified by a systematized examination of structural, optical, and periodontal factors. The basis for the proposed thought process is the concept of restorative volume that is a contemporary interpretation of restoration categories and their application. © 2012 Wiley Periodicals, Inc.

  20. Restoring proximal caries lesions conservatively with tunnel restorations

    Full Text Available Chun-Hung Chu1, May L Mei,1 Chloe Cheung,1 Romesh P Nalliah2 1Faculty of Dentistry, The University of Hong Kong, Hong Kong, People's Republic of China; 2Department of Restorative Dentistry and Biomaterials Sciences, Harvard School of Dental Medicine, Boston, MA, USA Abstract: The tunnel restoration has been suggested as a conservative alternative to the conventional box preparation for treating proximal caries. The main advantage of tunnel restoration over the conventional box or slot preparation includes being more conservative and increasing tooth integrity and strength by preserving the marginal ridge. However, tunnel restoration is technique-sensitive and can be particularly challenging for inexperienced restorative dentists. Recent advances in technology, such as the contemporary design of dental handpieces with advanced light-emitting diode (LED and handheld comfort, offer operative dentists better vision, illumination, and maneuverability. The use of magnifying loupes also enhances the visibility of the preparation. The advent of digital radiographic imaging has improved dental imaging and reduced radiation. The new generation of restorative materials has improved mechanical properties. Tunnel restoration can be an option to restore proximal caries if the dentist performs proper case selection and pays attention to the details of the restorative procedures. This paper describes the clinical technique of tunnel restoration and reviews the studies of tunnel restorations. Keywords: operative, practice, tunnel preparation, composite, amalgam, glass ionomer

  1. Restoration of longitudinal images.

    Hu, Y; Frieden, B R

    1988-01-15

    In this paper, a method of restoring longitudinal images is developed. By using the transfer function for longitudinal objects, and inverse filtering, a longitudinal image may be restored. The Fourier theory and sampling theorems for transverse images cannot be used directly in the longitudinal case. A modification and reasonable approximation are introduced. We have numerically established a necessary relationship between just-resolved longitudinal separation (after inverse filtering), noise level, and the taking conditions of object distance and lens diameter. An empirical formula is also found to well-fit the computed results. This formula may be of use for designing optical systems which are to image longitudinal details, such as in robotics or microscopy.

    We consider two different forms for a relativistic version of a linear restoring force. The pair comes from taking Hooke's law to be the force appearing on the right-hand side of the relativistic expressions: d"p"/d"t" or d"p"/d["tau"]. Either formulation recovers Hooke's law in the non-relativistic limit. In addition to these two forces, we…

    This document represents work conducted as part of the Wind River Watershed Restoration Project during its first year of funding through the Bonneville Power Administration (BPA). The project is a comprehensive effort involving public and private entities seeking to restore water quality and fishery resources in the basin through cooperative actions. Project elements include coordination, watershed assessment, restoration, monitoring, and education. Entities involved with implementing project components are the Underwood Conservation District (UCD), USDA Forest Service (USFS), U.S. Geological Survey--Columbia River Research Lab (USGS-CRRL), and WA Department of Fish & Wildlife (WDFW). Following categories given in the FY1999 Statement of Work, the broad categories, the related objectives, and the entities associated with each objective (lead entity in boldface) were as follows: Coordination--Objective 1: Coordinate the Wind River watershed Action Committee (AC) and Technical Advisory Committee (TAC) to develop a prioritized list of watershed enhancement projects. Monitoring--Objective 2: Monitor natural production of juvenile, smolt, and adult steelhead in the Wind River subbasin. Objective 3: Evaluate physical habitat conditions in the Wind River subbasin. Assessment--Objective 4: Assess watershed health using an ecosystem-based diagnostic model that will provide the technical basis to prioritize out-year restoration projects. Restoration--Objective 5: Reduce road related sediment sources by reducing road densities to less than 2 miles per square mile. Objective 6: Rehabilitate riparian corridors, flood plains, and channel morphology to reduce maximum water temperatures to less than 61 F, to increase bank stability to greater than 90%, to reduce bankfull width to depth ratios to less than 30, and to provide natural levels of pools and cover for fish. Objective 7: Maintain and evaluate passage for adult and juvenile steelhead at artificial barriers. Education

    The US Army Corps of Engineers has retained Idaho National Laboratory (INL) to conduct a study of past INL experiences and complete a report that identifies the processes that are needed for the development of renewable energy projects on government properties. The INL has always maintained expertise in power systems and applied engineering and INL’s renewable energy experiences date back to the 1980’s when our engineers began performing US Air Force wind energy feasibility studies and development projects. Over the last 20+ years of working with Department of Defense and other government agencies to study, design, and build government renewable projects, INL has experienced the do’s and don’ts for being successful with a project. These compiled guidelines for government renewable energy projects could include wind, hydro, geothermal, solar, biomass, or a variety of hybrid systems; however, for the purpose of narrowing the focus of this report, wind projects are the main topic discussed throughout this report. It is our thought that a lot of what is discussed could be applied, possibly with some modifications, to other areas of renewable energy. It is also important to note that individual projects (regardless the type) vary to some degree depending on location, size, and need but in general these concepts and directions can be carried over to the majority of government renewable energy projects. This report focuses on the initial development that needs to occur for any project to be a successful government renewable energy project.

    Changes in renewable energy markets, investments, industries, and policies have been so rapid in recent years that perceptions of the status of renewable energy can lag years behind the reality. This report captures that reality and provides a unique overview of renewable energy worldwide as of early 2011. The report covers both current status and key trends; by design, it does not provide analysis or forecast the future. Global energy consumption rebounded in 2010 after an overall downturn in 2009. Renewable energy, which experienced no downturn in 2009, continued to grow strongly in all end-use sectors - power, heat and transport - and supplied an estimated 16% of global final energy consumption. Renewable energy accounted for approximately half of the estimated 194 gigawatts (GW) of new electric capacity added globally during the year. Renewables delivered close to 20% of global electricity supply in 2010, and by early 2011 they comprised one quarter of global power capacity from all sources. In several countries, renewables represent a rapidly growing share of total energy supply, including heat and transport

    1969-01-01

    Some of the physical interpretations about image restoration are discussed. From the theory of information the unrealizability of an inverse filter can be explained by degradation of information, which is due to distortion on the recorded image. The image restoration is a time and space problem, which can be recognized from the theory of relativity (the problem of image restoration is related to Heisenberg's uncertainty principle in quantum mechanics). A detailed discussion of the relationship between information and energy is given. Two general results may be stated: (1) the restoration of the image from the distorted signal is possible only if it satisfies the detectability condition. However, the restored image, at the best, can only approach to the maximum allowable time criterion. (2) The restoration of an image by superimposing the distorted signal (due to smearing) is a physically unrealizable method. However, this restoration procedure may be achieved by the expenditure of an infinite amount of energy.

    2017-08-01

    Full Text Available Energy justice is increasingly being used as a framework to conceptualize the impacts of energy decision making in more holistic ways and to consider the social implications in terms of existing ethical values. Similarly, renewable energy technologies are increasingly being promoted for their environmental and social benefits. However, little work has been done to systematically examine the extent to which, in what ways and in what contexts, renewable energy technologies can contribute to achieving energy justice. This paper assesses the potential of renewable electricity technologies to address energy justice in various global contexts via a systematic review of existing studies analyzed in terms of the principles and dimensions of energy justice. Based on publications including peer reviewed academic literature, books, and in some cases reports by government or international organizations, we assess renewable electricity technologies in both grid integrated and off-grid use contexts. We conduct our investigation through the rubric of the affirmative and prohibitive principles of energy justice and in terms of its temporal, geographic, socio-political, economic, and technological dimensions. Renewable electricity technology development has and continue to have different impacts in different social contexts, and by considering the different impacts explicitly across global contexts, including differences between rural and urban contexts, this paper contributes to identifying and understanding how, in what ways, and in what particular conditions and circumstances renewable electricity technologies may correspond with or work to promote energy justice.

  1. Restoring Soil Quality to Mitigate Soil Degradation

    2015-05-01

    Full Text Available Feeding the world population, 7.3 billion in 2015 and projected to increase to 9.5 billion by 2050, necessitates an increase in agricultural production of ~70% between 2005 and 2050. Soil degradation, characterized by decline in quality and decrease in ecosystem goods and services, is a major constraint to achieving the required increase in agricultural production. Soil is a non-renewable resource on human time scales with its vulnerability to degradation depending on complex interactions between processes, factors and causes occurring at a range of spatial and temporal scales. Among the major soil degradation processes are accelerated erosion, depletion of the soil organic carbon (SOC pool and loss in biodiversity, loss of soil fertility and elemental imbalance, acidification and salinization. Soil degradation trends can be reversed by conversion to a restorative land use and adoption of recommended management practices. The strategy is to minimize soil erosion, create positive SOC and N budgets, enhance activity and species diversity of soil biota (micro, meso, and macro, and improve structural stability and pore geometry. Improving soil quality (i.e., increasing SOC pool, improving soil structure, enhancing soil fertility can reduce risks of soil degradation (physical, chemical, biological and ecological while improving the environment. Increasing the SOC pool to above the critical level (10 to 15 g/kg is essential to set-in-motion the restorative trends. Site-specific techniques of restoring soil quality include conservation agriculture, integrated nutrient management, continuous vegetative cover such as residue mulch and cover cropping, and controlled grazing at appropriate stocking rates. The strategy is to produce “more from less” by reducing losses and increasing soil, water, and nutrient use efficiency.

Moreover, BMIs are applied in conjunction with robotic orthoses for rehabilitation of lost motor function via neurofeedback training (restorative BMI. Using assistive BMI in a rehabilitation context does not automatically turn them into restorative devices. This perspective article suggests key features of restorative BMI and provides the supporting evidence:In summary, BMI may be referred to as restorative tools when demonstrating subsequently (i operant learning and progressive evolution of specific brain states/dynamics, (ii correlated modulations of functional networks related to the therapeutic goal, (iii subsequent improvement in a specific task, and (iv an explicit correlation between the modulated brain dynamics and the achieved behavioral gains.

    Changes in renewable energy markets, investments, industries, and policies have been so rapid in recent years that perceptions of the status of renewable energy can lag years behind the reality. This report captures that reality and provides a unique overview of renewable energy worldwide as of early 2010. The report covers both current status and key trends. By design, the report does not provide analysis, discuss current issues, or forecast the future. Many of the trends reflect the increasing significance of renewable energy relative to conventional energy sources (including coal, gas, oil, and nuclear). By 2010, renewable energy had reached a clear tipping point in the context of global energy supply. Renewables comprised fully one quarter of global power capacity from all sources and delivered 18 percent of global electricity supply in 2009. In a number of countries, renewables represent a rapidly growing share of total energy supply-including heat and transport. The share of households worldwide employing solar hot water heating continues to increase and is now estimated at 70 million households. And investment in new renewable power capacity in both 2008 and 2009 represented over half of total global investment in new power generation. Trends reflect strong growth and investment across all market sectors-power generation, heating and cooling, and transport fuels. Grid-connected solar PV has grown by an average of 60 percent every year for the past decade, increasing 100-fold since 2000. During the past five years from 2005 to 2009, consistent high growth year-after-year marked virtually every other renewable technology. During those five years, wind power capacity grew an average of 27 percent annually, solar hot water by 19 percent annually, and ethanol production by 20 percent annually. Biomass and geothermal for power and heat also grew strongly. Much more active policy development during the past several years culminated in a significant policy milestone

    Full Text Available Among the most visually striking river restoration projects are those that involve the creation of a new channel, often in a new alignment and generally with a form and dimensions that are different from those of the preproject channel. These channel reconstruction projects often have the objective of creating a stable, single-thread, meandering channel, even on rivers that were not historically meandering, on rivers whose sediment load and flow regime would not be consistent with such stable channels, or on already sinuous channels whose bends are not symmetrical. Such meandering channels are often specified by the Rosgen classification system, a popular restoration design approach. Although most projects of this type have not been subject to objective evaluation, completed postproject appraisals show that many of these projects failed within months or years of construction. Despite its, at best, mixed results, this classification and form-based approach continues to be popular because it is easy to apply, because it is accessible to those without formal training in fluvial geomorphology, and probably because it satisfies a deep-seated, although unrecognized, cultural preference for single-thread meandering channels. This preference is consistent with 18th-century English landscape theories, which held the serpentine form to be ideal and led to widespread construction of meandering channels on the country estates of the era. The preference for stability in restored channels seems to be widely accepted by practitioners and funders despite the fact that it is antithetical to research showing that dynamically migrating channels have the greatest ecological richness.

It comments the application of the Energy multi-year plan (PPE), evokes the content of a report by the French Court of Auditors about costs and means of implementation of transition (with notably the issue of maintenance of nuclear plants). It also shows that European Union is not a leader in renewable energies any more, that some European countries are changing sides, that figures and trends must be carefully compared with those in the field of fossil and nuclear energies, that all energies are not all the same, that jobs and system integration are also important, that investments and attractiveness of countries in renewable energies must be assessed, and that a mobilisation on small scale and consumer-based renewable energies is required. Ten recommendations are made for France to support the EU leadership development

    Morgado, A.M.L.S.; Simoes, J.B.; Correia, C.M.

    1996-01-01

    A good performance of high resolution nuclear spectrometry systems, at high pulse rates, demands restoration of baseline between pulses, in order to remove rate dependent baseline shifts. This restoration is performed by circuits named baseline restorers (BLRs) which also remove low frequency noise, such as power supply hum and detector microphonics. This paper presents simple circuits for baseline restoration based on a commercial current conveyor (CCII01). Tests were performed, on two circuits, with periodic trapezoidal shaped pulses in order to measure the baseline restoration for several pulse rates and restorer duty cycles. For the current conveyor based Robinson restorer, the peak shift was less than 10 mV, for duty cycles up to 60%, at high pulse rates. Duty cycles up to 80% were also tested, being the maximum peak shift 21 mV. The peak shift for the current conveyor based Grubic restorer was also measured. The maximum value found was 30 mV at 82% duty cycle. Keeping the duty cycle below 60% improves greatly the restorer performance. The ability of both baseline restorer architectures to reject low frequency modulation is also measured, with good results on both circuits

    2016-11-01

    Full Text Available This article offers an overview of what has been done until now on restorative research with children and opens up new inquires for future research. Most of the work has studied children’s exposure to nature and the restorative benefits this contact provides, focusing on the renewal of children’s psychological resources. The paper begins with an introduction to children’s current tendency toward an alienation from the natural world and sets out the objectives of the article. It is followed by four main sections. The first two sections report on what we already know in this research area, distinguishing between children with normal mental capabilities and those suffering from attention-deficit hyperactivity disorder (ADHD. The findings gathered in these sections suggest that children’s contact with nature improves their mood and their cognitive functioning, increases their social interactions and reduces ADHD symptoms. The next section describes five suggestions for future research: 1 the need for considering the relational dynamics between the child and the environment in restoration research, and the concept of constrained restoration; 2 the possibility of restorative needs arising from understimulation; 3 the importance of considering children’s social context for restoration; 4 the relationship between restoration and pro-social and pro-environmental behaviors and 5 children’s restorative environments other than nature. We close by making some final remarks about the importance of restoring daily depleted resources for children’s healthy functioning.

    Hepatocellular carcinoma (HCC) exhibits cellular heterogeneity and embryonic stem-cell-related genes are preferentially overexpressed in a fraction of cancer cells of poorly differentiated tumors. However, it is not known whether or how these cancer cells contribute to tumor initiation and progression. Here, our data showed that increased expression of pluripotency transcription factor Nanog in cancer cells correlates with a worse clinical outcome in HCC. Using the Nanog promoter as a reporter system, we could successfully isolate a small subpopulation of Nanog-positive cells. We demonstrate that Nanog-positive cells exhibited enhanced ability of self-renewal, clonogenicity, and initiation of tumors, which are consistent with crucial hallmarks in the definition of cancer stem cells (CSCs). Nanog(Pos) CSCs could differentiate into mature cancer cells in in vitro and in vivo conditions. In addition, we found that Nanog(Pos) CSCs exhibited resistance to therapeutic agents (e.g., sorafenib and cisplatin) and have a high capacity for tumor invasion and metastasis. Knock-down expression of Nanog in Nanog(Pos) CSCs could decrease self-renewal accompanied with decreased expression of stem-cell-related genes and increased expression of mature hepatocyte-related genes. Overexpression of Nanog in Nanog(Neg) cells could restore self-renewal. Furthermore, we found that insulin-like growth factor (IGF)2 and IGF receptor (IGF1R) were up-regulated in Nanog(Pos) CSCs. Knock-down expression of Nanog in Nanog(Pos) CSCs inhibited the expression of IGF1R, and overexpression of Nanog in Nanog(Neg) cells increased the expression of IGF1R. A specific inhibitor of IGF1R signaling could significantly inhibit self-renewal and Nanog expression, indicating that IGF1R signaling participated in Nanog-mediated self-renewal. These data indicate that Nanog could be a novel biomarker for CSCs in HCC, and that Nanog could play a crucial role in maintaining the self-renewal of CSCs through the IGF1R

    On January 23, 2008, the European Commission presented proposals in the form of a directive in an effort to give more specific shape to the objective adopted in the spring, i.e. to increase to 20% by 2020 the share of renewable energies in energy consumption in the Community. The proposal was to include legally binding goals for the overall share of renewable energy sources and the share of biofuels in the transport sector. The proposed directive on 'promoting the use of energy from renewable sources' calls upon each member state to ensure that its share of energy from renewable sources in the total energy consumption in 2020 at least corresponds to the target mentioned in Annex I Part A. In addition to the targets, the EU Commission charted a tentative course towards a minimum increase in the share of renewable energies in the period between 2011 and 2020. Finally, the member states are obliged to adopt national action plans. Unfortunately, the EU is missing an important target in its proposed directive: It should establish a framework for harmonized conditions promoting the use of renewable energies. One aspect to be welcomed is the introduction of a system of certificates of origin. It represents the entry, in principle, into a trading system with certificates of origin. The Green Package incorporates a wealth of new approaches. They will have to be tested and, if necessary, supplemented. Something else is evident, however: The directive established the foundations of a vast number of new regulations and red tape. (orig.)

    1998-12-31

    This publication includes a compiled presentation of various aspects concerning the possible transformation of some European islands into renewable energy communities and these projects were presented by a selection of pioneer islands at the first European Seminar on Renewable Energy Islands, held on the Danish island of Samsoee, 29-30 June 1998. This issue has increased in importance with the presentation of the ambitious EU-White Paper: `Energy for the future: Renewable Sources of Energy` which was adopted in 1998. One of the key elements of the strategy for an accelerated implementation of renewable energy is to transform 100 localities within Europe into communities which are to be 100% self-sufficient with renewable energy before 2010. In line with this strategy, the Danish Government appointed the island of Samsoe towards the end of 1997 to be the first `official` Danish, renewable energy island. This is to serve as a demonstration project for other local communities, both in Denmark as well as in the rest Europe. Gothland, Madeira, Canary Islands, Cape Verde, Arki, Crete, Minorca and Orkney Islands were represented. Environmental advantages of wind, solar and wave power for distant island communities were indicated. Serious savings would be achieved by limitation of fossil fuel import and utilization of local resources. (EG)

    This paper analyzes China's policy approach to renewable energies and assesses how effectively China has met the ideal of appropriate interactions between renewable energy policy and renewable energy industrial policy. First we briefly discuss the interactions between these two policies. Then we outline China's key renewable energy and renewable industrial policies and find that China's government has well recognized the need for this policy interaction. After that, we study the achievements and problems in China's wind and solar PV sector during 2005–2012 and argue that China's policy approach to renewable energies has placed priority first on developing a renewable energy manufacturing industry and only second on renewable energy itself, and it has not effectively met the ideal of appropriate interactions between renewable energy policy and renewable energy industrial policy. Lastly, we make an in-depth analysis of the three ideas underlying this policy approach, that is, the green development idea, the low-carbon leadership idea and indigenous innovation idea. We conclude that Chinas' policy approach to renewable energies needs to enhance the interactions between renewable energy policy and renewable energy industrial policy. The paper contributes to a deeper understanding of China's policy strategy toward renewable energies. -- Highlights: •Interactions between renewable energy policy and renewable energy industrial policy are discussed. •China's key renewable energy and renewable energy industrial policies are outlined. •Two empirical cases illustrate China's policy approach to renewable energies. •We argue that China needs to enhance the interactions between the two policies. •Three ideas underlie China's policy approach to renewable energies

  19. The role of renewables in the energy crisis

    2014-03-01

    Full Text Available The recent progress of human kind has so far been strongly related to the use of fossil fuels. Nowadays, the uncontrolled growth of their use is producing a series of threats such as local pollution, global warming, and the unbalance between their growing demand and their progressive depletion is creating serious geopolitical frictions which may put at risk our civilization. While the nuclear option is seriously questioned in the Western world, the growth of renewable energy sources (RES is creating the illusion that they may just replace fossil fuels and become a sort of panacea overcoming all aforementioned threats. Some of the shortcomings of this way of thinking are underlined in this paper. Actually, the correct answer is a combination of two factors: on one side the use of renewable energy sources, but on the other side the adoption of energy efficiency measures in order to rationalize the energy demand.

    Full Text Available In Poland, as in other European Union countries, the project finance structure is used to finance investments in the field of energy. This method investment financing is often used in the world. The upward trend inhibition in recent periods has been due to the global financial crisis and financial instability in the euro zone. On account of the necessity to develop the energy infrastructure associated with renewable sources, the considerable strengthening in the use of project finance techniques can be expected. The particular progression may be observed in the case of public-private partnership (ppp, where public investments are carried out by private companies. Companies, in case of investment realization in the field of ppp, almost always use project finance, because it is a beneficial way to separate the risks associated with an investment from the balance sheet of the compa-ny.

  1. Predictable repair of provisional restorations.

    Science.gov (United States)

    Hammond, Barry D; Cooper, Jeril R; Lazarchik, David A

    2009-01-01

    The importance of provisional restorations is often downplayed, as they are thought of by some as only "temporaries." As a result, a less-than-ideal provisional is sometimes fabricated, in part because of the additional chair time required to make provisional modifications when using traditional techniques. Additionally, in many dental practices, these provisional restorations are often fabricated by auxillary personnel who may not be as well trained in the fabrication process. Because provisionals play an important role in achieving the desired final functional and esthetic result, a high-quality provisional restoration is essential to fabricating a successful definitive restoration. This article describes a method for efficiently and predictably repairing both methacrylate and bis-acryl provisional restorations using flowable composite resin. By use of this relatively simple technique, provisional restorations can now be modified or repaired in a timely and productive manner to yield an exceptional result. Successful execution of esthetic and restorative dentistry requires attention to detail in every aspect of the case. Fabrication of high-quality provisional restorations can, at times, be challenging and time consuming. The techniques for optimizing resin provisional restorations as described in this paper are pragmatic and will enhance the delivery of dental treatment.

  2. When renewable energy met sustainable growth. Regulation, cost reduction, and the rise of renewable energy in the United States

    International Nuclear Information System (INIS)

    Stephens, Samantha

    2016-01-01

    Historically and famously fossil-fuel dependent, the U.S. energy and electricity mixes are evolving quickly as costs fall for renewables, regulations mandate their implementation, and fiscal policy incentivizes their installation. The investment and production tax credits (ITC and PTC) as well as power purchase agreements (PPAs) are well-known for their contributions to the development of solar and wind capacity, and the recent extensions of these credits has led to a positive outlook for continued growth in installations and generation. In addition, the green power market is experiencing record participation, as tracking the positive environmental externalities of renewable power has become important to meet renewable portfolio standards, which mandate implementation of renewable energy by state. Cost reduction is further taking place globally due to technological advances and economies of scale, which serves as another key driver for development. Of course, challenges are still present, particularly due to a plentiful and inexpensive domestic fossil fuel supply, uneven application of regulation and incentives state-by-state, and the uncertainty of continued political support. Even so, a progressive lowering of traditional barriers is leading to the potential for widespread deployment of renewables across the American landscape. (author)

    Full Text Available Lakes are suffering from different stress factors and need to be restored using different approaches. The eutrophication remains as the main water quality management problem for inland waters: both lakes and reservoirs. The way to curb the degradation is to stop the nutrient sources and to accelerate the restoration with help of in-lake technologies. Especially lakes with a long retention time need (eco- technological help to decrease the nutrient content in the free water. The microbial and other organic matter from sewage and other autochthonous biomasses, causes oxygen depletion, which has many adverse effects. In less developed countries big reservoirs function as sewage treatment plants. Natural aeration solves problems only partly and many pollutants tend to accumulate in the sediments. The acidification by acid rain and by pyrite oxidation has to be controlled by acid neutralizing technologies. Addition of alkaline chemicals is useful only for soft waters, and technologies for (microbial alkalinization of very acidic hardwater mining lakes are in development. The corrective measures differ from those in use for eutrophication control. The salinization and water shortage mostly occurs if more water is used than available. L. Aral, L. Tschad, the Dead Sea or L. Nasser belong to waters with most severe environmental problems on a global scale. Their hydrologic regime needs to be evaluated. The inflow of salt water at the bottom of some mining lakes adds to stability of stratification, and thus accumulation of hydrogen sulphide in the monimolimnion of the meromictic lakes. Destratification, which is the most used technology, is only restricted applicable because of the dangerous concentrations of the byproducts of biological degradation. The contamination of lakes with hazardous substances from industry and agriculture require different restoration technologies, including subhydric isolation and storage, addition of nutrients for better self

    The EurObserv'ER policy profiles give a snapshot of the renewable energy policy in the EU Member States. The promotion of renewable electricity in Romania relies primarily on a renewable quota scheme. Since 2017 the scheme has been closed for new projects. Renewable heating and cooling is promoted through investment subsidies. Renewable energy sources in the transport sector are promoted by a bio-fuels quota scheme and indirectly through a subsidy scheme for the purchase of electric vehicles

    1999-01-01

    A short analysis of the main topics of the IPS Symposium Peatland Restoration and Reclamation, Duluth, Minnesota, USA, 1998 is given. It has been single-mindedly recommended in Estonia so far that harvested peatland surfaces should be levelled and outflows shut. But following these recommendations will lead to an unfounded formation of marshy areas with a very low growth of plants. The reclamation of harvested peatlands for agricultural purposes is expensive and there is no commercial need for agricultural land in today's Estonia now. In the author's opinion the foreflows and intermediate ditches should be left open which would favour the growth of the brushwood to grow later into the forest of commercial value. (author)

    2008-01-01

    Whereas the contribution from renewable energies in the electrical power market is increasing rapidly, similar progress in the heat market is yet to be made. A prerequisite for progress is the development of innovative support instruments that transcend the usual support through public subsidies or tax reductions. We present an overview of the various classes of possible instruments. Some particularly interesting instruments will be selected and evaluated, comparing them qualitatively and quantitatively for the case of Germany. The most favourable model is found to be a new, allocation-financed model known as the Bonus Model. This model will be described in more detail

  11. Restorative Justice in Children.

    An important, and perhaps uniquely human, mechanism for maintaining cooperation against free riders is third-party punishment. Our closest living relatives, chimpanzees, will not punish third parties even though they will do so when personally affected. Until recently, little attention has been paid to how punishment and a sense of justice develop in children. Children respond to norm violations. They are more likely to share with a puppet that helped another individual as opposed to one who behaved harmfully, and they show a preference for seeing a harmful doll rather than a victim punished. By 6 years of age, children will pay a cost to punish fictional and real peers, and the threat of punishment will lead preschoolers to behave more generously. However, little is known about what motivates a sense of justice in children. We gave 3- and 5-year-old children--the youngest ages yet tested--the opportunity to remove items and prevent a puppet from gaining a reward for second- and third-party violations (experiment 1), and we gave 3-year-olds the opportunity to restore items (experiment 2). Children were as likely to engage in third-party interventions as they were when personally affected, yet they did not discriminate among the different sources of harm for the victim. When given a range of options, 3-year-olds chose restoration over removal. It appears that a sense of justice centered on harm caused to victims emerges early in childhood and highlights the value of third-party interventions for human cooperation.

    The MENA Renewables Status Report is an outcome of ADIREC, the Abu Dhabi International Renewable Energy Conference. The report provides a status overview of renewable energy markets, industry, policy and investment trends in the region, drawing on the most recent data available. It is produced in cooperation with over 50 contributors and researchers in the region and reveals massive growth in the renewable energy markets of the Middle East and North Africa (MENA). Regional investment topped US$2.9 billion in 2012, up 40% from 2011 and 650% from 2004. With over 100 projects under development, the region could see a 450% increase in non-hydro renewable energy generating capacity in the next few years. For the report, the 21 MENA countries were clustered into two sub-groups: Net Oil-Exporting Countries (NOEC) -- Algeria, Bahrain, Egypt, Iran, Iraq, Kuwait, Libya, Oman, Qatar, Saudi Arabia, Syria, United Arab Emirates, and Yemen; and Net Oil-Importing Countries (NOIC) -- Djibouti, Israel, Jordan, Lebanon, Malta, Morocco, Palestine, and Tunisia.

This restoration provides habitat for a number of plant and animal species that are restricted to or found mostly in longleaf pine...

  19. Restoration of Lost Lake, recovery of an impacted Carolina Bay

    International Nuclear Information System (INIS)

    Wike, L.D.; Gladden, J.B.; Mackey, H.E. Jr.; Rogers, V.A.

    1995-01-01

    Lost Lake is one of approximately 200 Carolina bays found on the Savannah River Site (SRS). Until 1984 Lost Lake was contaminated by heavy metals and solvents overflowing from a nearby settling basin. Up to 12 inches of surface soil and all vegetation was removed from the bay as part of a RCRA removal action. A plan for restoration was initiated in 1989 and implemented in 1990 and 1991. Extensive planning led to defined objectives, strategies, treatments, and monitoring programs allowing successful restoration of Lost Lake. The primary goal of the project was to restore the wetland ecosystem after a hazardous waste clean up operation. An additional goal was to study the progress of the project and the success of the restoration activity. Several strategy considerations were necessary in the restoration plan. The removal of existing organic soils had to have compensation, a treatment scheme for planting and the extent of manipulation of the substrate had to be considered, monitoring decisions had to be made, and the decision whether or not to actively control the hydrology of the restored system

    Full Text Available The Energy-CSOP facilitates broad equity participation of citizens without assets or savings in a regulated public energy utility. As the CSOP is designed for regulated markets with guaranteed prices, regulated market access and long-term relationships between producer and consumer, the energy market is predestined. A CSOP trust can be set up for a renewable energy plant (e.g., a biogas reactor, a solar panel, a windmill or a geothermic drill. European states have set an ambitious target to reach 20% share of energy from renewable sources by 2020. Germany as Europe’s green energy leader could become a pioneer in CSOP implementation. Small communities in Europe would benefit from the increased share of renewable energy resources.

    2005-01-01

    About 3 quarter of the Italian electric power comes from fossil fuel power plants. The rest is generated from hydropower, few comes from biomass and wind energy and a very few from geothermal energy (2% of the national production). However, the situation is changing and geothermal energy, with only 5 TWh, makes Italy the European leader in this domain and the world number 4 behind USA, Philippines and Mexico. The renewable sources represent 18.5% of the total Italian energy production. During the last five years, the renewable energy sources have developed rapidly: +80% per year for the wind energy, +32% per year for biomass and about +3% per year for geothermal energy. Moreover, the Italian government is implementing incentives for the development of renewable energy sources. This article gives an overview of the situation. (J.S.)

  8. China's renewable energy policy: Commitments and challenges

    International Nuclear Information System (INIS)

    Wang Feng; Yin Haitao; Li Shoude

    2010-01-01

    The passing of the Renewable Energy Law (REL) in 2005 demonstrated China's commitment to renewable energy development. In the 3 years after the REL, China's renewable electricity capacity grew rapidly. From 2006 to 2008, China's wind capacity installation more than doubled every year for 3 years in a row. However, three facts prevent us from being optimistic about China's renewable electricity future. First, considered as a share of total capacity, renewable electricity capacity is decreasing instead of increasing. This is due simply to the rapid growth of fossil fuel capacity. Second, a significant amount of renewable generation capacity is wasted because it is not connected to the electricity grid. Finally, renewable electricity plants are running at a low level of efficiency. Based on an in-depth analysis of China's existing renewable energy policy, we suggest that these challenges should be dealt with by introducing a market-based mandatory renewable portfolio requirement coupled with strong regulatory monitoring of grid enterprises.

  9. Renewable energy technology acceptance in Peninsular Malaysia

    International Nuclear Information System (INIS)

    Kardooni, Roozbeh; Yusoff, Sumiani Binti; Kari, Fatimah Binti

    2016-01-01

    Despite various policies, renewable energy resources have not been developed in Malaysia. This study investigates the factors that influence renewable energy technology acceptance in Peninsular Malaysia and attempts to show the impact of cost and knowledge on the perceived ease of use and perceived usefulness of renewable energy technology. The results show that cost of renewable energy has an indirect effect on attitudes towards using renewable energy through the associated impact on the perceived ease of use and perceived usefulness. The results also indicate that public knowledge in Peninsular Malaysia does not affect perceived ease of use, although the positive impact of knowledge on perceived usefulness is supported. Furthermore, our results show that the current business environment in Peninsular Malaysia does not support the adoption of renewable energy technology, and thus, renewable energy technology is not commercially viable in Peninsular Malaysia. Additionally, the population of Peninsular Malaysia associates the use of renewable energy with a high level of effort and therefore has a negative attitude towards the use of renewable energy technology. There is, therefore, a definite need to pay more attention to the role of public perception and awareness in the successes and failures of renewable energy policy. - Highlights: • Public acceptance is an essential element in the diffusion of renewable energy. • Perceived ease of use and perceived usefulness affect intention to use renewables. • It is important to reduce the cost of renewable energy, particularly for end users. • Renewable energy policies should address issues of public perception and awareness.

    1991-07-01

    A comprehensive analysis, region by region, of the actually accessible renewable energies at a given horizon, is presented. The same methodology as the one employed to derive ``proven fossil energy reserves`` from ``energy resources`` is adopted, in which resources are defined by quantitative information on physical potential, while reserves take into account technical and economical accessibility. As renewable resources are fluctuating with time and are diluted in space and not readily transportable or storeable, it is necessary to consider the presence of populations or activities near enough to be able to profit by these diluted and volatile energies.

    2011-01-01

    The world has to face increasing energy needs while it is today dependent of fossil fuels at 80%. Getting out of the fossil fuels dependence model requires an important effort to promote the energy saving and the carbon-free energies as well, and in particular the renewable energy sources. Taking all this information into account, the authors evaluate the global share that renewable energies could represent in the energy mix, in France and in the entire world. This share represents today only 10% of the energy consumed, but will it remain marginal or will it become important and eventually prominent? (J.S.)

    This work expands upon Swallow's theoretical analysis of interactions between renewable and non-renewable resources. In this comment the interaction is such that the renewable resource prefers the non-renewable environment, as opposed to SwallowÕs (op cit) case of the non-renewable environment being essential to the renewable resource. We find that this difference strongly affects the results, and makes the resources change from being complements to being substitutes, i.e. in the essential ca...

    We study the transition between non-renewable and renewable energy sources with adjustment costs over the production capacity of renewable energy. Assuming constant variable marginal costs for both energy sources, convex adjustment costs and a more expensive renewable energy, we show the following. With sufficiently abundant non-renewable energy endowments, the dynamic equilibrium path is composed of a first time phase of only non-renewable energy use followed by a transition phase substituti...

  18. Analysis and perspectives of the government programs to promote the renewable electricity generation in Brazil

    International Nuclear Information System (INIS)

    Ruiz, B.J.; Rodriguez, V.; Bermann, C.

    2007-01-01

    Government programs to encourage renewable electricity production in Brazil are analyzed in order to evaluate aims and identify problems in the execution of such programs in order to provide ideas to channel them. In terms of methodology, the analysis is based in a chronologic study of the programs, in order to establish whether or not renewable energy policies have been linked. The paper concludes that already-executed programs and those in progress have deficiencies that hinder the achievement of their goals; therefore diversification policies for renewable energy will not be achieved in the foreseen timeframe. Therefore, certain policy changes are proposed

    2017-04-01

    Gastric cancer is a leading cause of cancer-related mortality worldwide. Cancer stem cells are the source of tumor recurrence and metastasis. Self-renewal is a marker of cancer stem cells and also the basis of long-lasting survival and tumor progression. Although the mechanism of gastric cancer stem cell self-renewal is not clear, there are several signaling pathways and environmental factors known to be involved. This mini review describes recent developments in the self-renewal signaling pathway of gastric cancer stem cell research. Advancements made in this field of research will likely support the development of novel therapeutic strategies for gastric cancer.

  20. Sustainability of hydropower as source of renewable and clean energy

    International Nuclear Information System (INIS)

    Luis, J; Sidek, L M; Desa, M N M; Julien, P Y

    2013-01-01

    Hydroelectric energy has been in recent times placed as an important future source of renewable and clean energy. The advantage of hydropower as a renewable energy is that it produces negligible amounts of greenhouse gases, it stores large amounts of electricity at low cost and it can be adjusted to meet consumer demand. This noble vision however is becoming more challenging due to rapid urbanization development and increasing human activities surrounding the catchment area. Numerous studies have shown that there are several contributing factors that lead towards the loss of live storage in reservoir, namely geology, ground slopes, climate, drainage density and human activities. Sediment deposition in the reservoir particularly for hydroelectric purposes has several major concerns due to the reduced water storage volume which includes increase in the risk of flooding downstream which directly effects the safety of human population and properties, contributes to economic losses not only in revenue for power generation but also large capital and maintenance cost for reservoir restorations works. In the event of functional loss of capabilities of a hydropower reservoir as a result of sedimentation or siltation could lead to both economical and environmental impact. The objective of this paper is aimed present the importance of hydropower as a source of renewable and clean energy in the national energy mix and the increasing challenges of sustainability.

  1. Dynamic life cycle assessment (LCA) of renewable energy technologies

    Energy Technology Data Exchange (ETDEWEB)

    Pehnt, M. [Institut for Energy and Environmental Research, Heidelberg (Germany)

    2006-01-01

    Before new technologies enter the market, their environmental superiority over competing options must be asserted based on a life cycle approach. However, when applying the prevailing status-quo Life Cycle Assessment (LCA) approach to future renewable energy systems, one does not distinguish between impacts which are 'imported' into the system due to the 'background system' (e.g. due to supply of materials or final energy for the production of the energy system), and what is the improvement potential of these technologies compared to competitors (e.g. due to process and system innovations or diffusion effects). This paper investigates a dynamic approach towards the LCA of renewable energy technologies and proves that for all renewable energy chains, the inputs of finite energy resources and emissions of greenhouse gases are extremely low compared with the conventional system. With regard to the other environmental impacts the findings do not reveal any clear verdict for or against renewable energies. Future development will enable a further reduction of environmental impacts of renewable energy systems. Different factors are responsible for this development, such as progress with respect to technical parameters of energy converters, in particular, improved efficiency; emissions characteristics; increased lifetime, etc.; advances with regard to the production process of energy converters and fuels; and advances with regard to 'external' services originating from conventional energy and transport systems, for instance, improved electricity or process heat supply for system production and ecologically optimized transport systems for fuel transportation. The application of renewable energy sources might modify not only the background system, but also further downstream aspects, such as consumer behavior. This effect is, however, strongly context and technology dependent. (author)

    2003-01-01

    Renewable energy today is at a critical stage of development: renewable technologies are maturing, and costs for some technologies are in the competitive range. Beyond the energy they produce, renewable energy technologies offer a variety of other benefits towards the achievement of sustainable development goals. This promise has led to all IEA governments to support their greater development. But, while renewables markets are growing strongly, additional steps must be taken to accelerate the achievement of sustainable, large-scale markets. This report by the IEA's Renewable Energy Working Party outlines those steps, and the benefits of moving renewable energy into the mainstream

    .4%. Global energy demand increased an estimated 2.1% in 2017 due to economic growth in emerging economies as well as population growth. Renewable energy uptake is not keeping pace with this increasing energy demand and the continuous investment in fossil and nuclear capacity. In the power sector, the transition to renewables is under way but is progressing more slowly than is possible or desirable. A commitment made under the 2015 Paris climate agreement to limit global temperature rise to 'well below' 2 degrees Celsius above pre-industrial levels makes the nature of the challenge much clearer. If the world is to achieve the target set in the Paris agreement, then heating, cooling and transport will need to follow the same path as the power sector - and fast. These sectors have seen: Little change in renewables uptake in heating and cooling: Modern renewable energy supplied approximately 10% of total global heat production in 2015. National targets for renewable energy in heating and cooling exist in only 48 countries around the world, whereas 146 countries have targets for renewable energy in the power sector. Small changes are under way. In India, for example, installations of solar thermal collectors rose approximately 25% in 2017 as compared to 2016. China aims to have 2% of the cooling loads of its buildings come from solar thermal energy by 2020. In transport, increasing electrification is offering possibilities for renewable energy uptake despite the dominance of fossil fuels: More than 30 million two- and three-wheeled electric vehicles are being added to the world's roads every year, and 1.2 million passenger electric cars were sold in 2017, up about 58% from 2016. Electricity provides 1.3% of transport energy needs, of which about one-quarter is renewable, and biofuels provide 2.9%. Overall, however, 92% of transport energy demand continues to be met by oil, and only 42 countries have national targets for the use of renewable energy in transport. For

    IRENA Renewable Energy Country Profiles take stock of the latest developments in the field of renewables at country level around the world. Each profile combines analysis by IRENA's specialists with the latest available country data and additional information from a wide array of sources. The resulting reports provide a brief yet comprehensive picture of the situation with regard to renewable energy, including energy supply, electrical generation and grid capacity, and access. Energy policies, targets and projects are also considered, along with each country's investment climate and endowment with renewable energy resources. The energy statistics presented here span the period from 2009 until 2012, reflecting varying timelines in the source material. Since data availability differs from country to country, wider regional comparisons are possible only for the latest year with figures available for every country included. Despite the time lag in some cases, the evident differences and disparities between countries and regions around the world remain striking. The current package of country profiles is just a starting point. The geographic scope will continue to expand, and existing profiles will be enhanced with new indicators, with the whole series maintained as a live product on the IRENA website (www.irena.org)

  8. The USNCR license renewal process

    International Nuclear Information System (INIS)

    Kuo, Pao-Tsin

    2002-01-01

    The US Congress promulgated a law in 1954, entitled 'Atomic Energy Act'. This Act states that operating licenses for commercial nuclear power plants are limited to a fixed term of 40 years, but they may be renewed for a period not to exceed 20 years. The terms were established mainly for economic considerations, not based on technical limitations. The U.S. Nuclear Regulatory Commission (USNRC) published the license renewal rule, Title 10 of the Code of Federal Regulations, Part 54 (10 CFR Part 54), in December, 1991. The rule has since been amended in May, 1995. The underlying principle of the rule is that the regulatory process is adequate for ensuring safety of operating plants. The regulatory process includes NRC's issuance of Orders, Bulletins, Generic Letters, and Information Notices, as well as a number of special inspections in addition to the continuous oversight and routine inspection activities performed by on-site inspectors. Because of this comprehensive regulatory process, compilation of the current license basis or re-verification of the current licensing basis is not considered necessary for a license renewal review. The USNRC also determined on the basis of the findings of its research programs that active structures and components are well maintained by the existing programs. Therefore, the focus of the license renewal review is on passive, long-lived structures and components and on time-limited ageing analyses. The time-limited ageing analyses are for those structures and components which were originally designed to a 40 year service life

    On June 27 and 28, 1989, the US Department of Energy (DOE) national laboratories were convened to discuss plans for the development of a National Energy Strategy (NES) and, in particular, the analytic needs in support of NES that could be addressed by the laboratories. As a result of that meeting, interlaboratory teams were formed to produce analytic white papers on key topics, and a lead laboratory was designated for each core laboratory team. The broad-ranging renewables assignment is summarized by the following issue statement from the Office of Policy, Planning and Analysis: to what extent can renewable energy technologies contribute to diversifying sources of energy supply What are the major barriers to greater renewable energy use and what is the potential timing of widespread commercialization for various categories of applications This report presents the results of the intensive activity initiated by the June 1989 meeting to produce a white paper on renewable energy.

  15. Power marketing and renewable energy

    International Nuclear Information System (INIS)

    Fang, J.M.

    1997-01-01

    Power marketing refers to wholesale and retail transactions of electric power made by companies other than public power entities and the regulated utilities that own the generation and distribution lines. The growth in power marketing has been a major development in the electric power industry during the last few years, and power marketers are expected to realize even more market opportunities as electric industry deregulation proceeds from wholesale competition to retail competition. This Topical Issues Brief examines the nature of the power marketing business and its relationship with renewable power. The information presented is based on interviews conducted with nine power marketing companies, which accounted for almost 54% of total power sales by power marketers in 1995. These interviews provided information on various viewpoints of power marketers, their experience with renewables, and their respective outlooks for including renewables in their resource portfolios. Some basic differences exist between wholesale and retail competition that should be recognized when discussing power marketing and renewable power. At the wholesale level, the majority of power marketers stress the commodity nature of electricity. The primary criteria for developing resource portfolios are the same as those of their wholesale customers: the cost and reliability of power supplies. At the retail level, electricity may be viewed as a product that includes value-added characteristics or services determined by customer preferences

    1998-04-01

    The recent formation of the Quebec Association for the Production of Renewable Energy (l`Association quebecoise de la production d`energie renouvelable - AQPER) was announced. The Association is becoming the centre of the Quebec private electricity generation industry. By communicating the industry`s message to the public the organization gives much needed visibility to renewable resources, new forms of energy and sustainable development. The new group is an outgrowth of the former Quebec Association of Private Hydroelectricity Producers. In its new reincarnation, the organization represents all forms of renewables, small and medium hydro, wind, solar, forest and agricultural biomass and urban waste. With deregulation of the electricity market, specifically the creation of the Regie de l`energie` in Quebec, the wider role is a welcome boost for renewable energy development in the province. In one of its first actions the AQPER recommended that all hydroelectric sites up to 50 MW be reserved for development exclusively by the private sector, in conformity with the Quebec energy policy announced in 1996.

    2004-01-01

    The Dutch policy goal is to achieve a share of 17% renewable electricity in the domestic demand in 2020, corresponding to 18-24 TWh. It is uncertain whether and under which conditions this aim can be achieved. This paper aims to explore the feasible deployment of renewable electricity production in the Netherlands until 2020 by evaluating different images representing policies and societal preferences. Simultaneously, the most promising technologies for different settings are investigated and identified. First Dutch policy goals, governmental policy measures and definitions of renewable electricity are discussed. Second, a comparison is made of four existing studies that analyze the possible developments of renewable electricity production in the coming decades. Finally, three images are set up with emphasis on the different key factors that influence the maximum realizable potential. Results indicate onshore wind, offshore wind and large-scale biomass plants as most promising, robust options in terms of economical performance, ecological sustainability and high technical implementation rate. In the image with high implementation rates, an annual production of 42 TWh may be achieved in 2020, while under stringent economical or ecological criteria, about 25 TWh may be reached. When only the robust options are considered, 9-22 TWh can be realized. The analysis illustrates the importance of taking the different key factors mentioned influencing implementation into account. Doing so allows for identification of robust and less robust technological options under different conditions

    As cleanup workers excavate pits and tear down buildings at the Fernald site in southwest Ohio, site ecologists are working side-by-side to create thriving wetlands and develop the early stages of forest, prairie, and savanna ecosystems to restore natural resources that were impacted by years of site operations. In 1998, the U.S. Department of Energy-Fernald Office (DOE-FN) and its cleanup contractor, Fluor Fernald, Inc., initiated several ecological restoration projects in perimeter areas of the site (e.g., areas not used for or impacted by uranium processing or waste management). The projects are part of Fernald's final land use plan to restore natural resources over 904 acres of the 1,050-acre site. Pete Yerace, the DOE-FN Natural Resource Trustee representative is working with the Fernald Natural Resource Trustees in an oversight role to resolve the state of Ohio's 1986 claim against DOE for injuries to natural resources. Fluor Fernald, Inc., and DOE-FN developed the ''Natural Resource Restoration Plan'', which outlines 15 major restoration projects for the site and will restore injured natural resources at the site. In general, Fernald's plan includes grading to maximize the formation of wetlands or expanded floodplain, amending soil where topsoil has been removed during excavation, and establishing native vegetation throughout the site. Today, with cleanup over 35 percent complete and site closure targeted for 2006, Fernald is entering a new phase of restoration that involves heavily remediated areas. By working closely with engineers and cleanup crews, site ecologists can take advantage of remediation fieldwork (e.g., convert an excavated depression into a wetland) and avoid unnecessary costs and duplication. This collaboration has also created opportunities for relatively simple and inexpensive restoration of areas that were discovered during ongoing remediation. To ensure the survival of the plant material in heavily

In partnership with the Oregon Military Department, the Department of Energy used the award to assess and evaluate renewable resources in a 2,622-acre location in Lake County, central Oregon, leading to future development of up to 200 MW of solar electricity. The Oregon Military Department (Military) acquired a large parcel of land located in south central Oregon. The land was previously owned by the US Air Force and developed for an Over-the-Horizon Backscatter Radar Transmitter Facility, located about 10 miles east of the town of Christmas Valley. The Military is investigating a number of uses for the site, including Research and Development (R&D) laboratory, emergency response, military operations, developing renewable energy and related educational programs. One of the key potential uses would be for a large scale solar photovoltaic power plant. This is an attractive use because the site has excellent solar exposure; an existing strong electrical interconnection to the power grid; and a secure location at a moderate cost per acre. The project objectives include: 1. Site evaluation 2. Research and Development (R&D) facility analysis 3. Utility interconnection studies and agreements 4. Additional on-site renewable energy resources analysis 5. Community education, outreach and mitigation 6. Renewable energy and emergency readiness training program for veterans

    Although the need to decarbonise our global economy and thus in particular the supply of energy to limit the global temperature increase is internationally undisputed the German politics in 2014 has significantly contributed less compared to previous years in order to attain this objective. The expansion of renewable energies in the electricity sector has decelerated significantly; and in the heating and mobility area no new impulses were set in relation to renewable energies. In addition, a dramatic fallen oil price makes it difficult to increase the use of renewable energy supply. Based on these deteriorated framework conditions compared to conditions of the previous years, the developments in Germany of 2014 are shown in the electricity, heat and transport sector in the field of renewable energy. For this purpose - in addition to a discussion of the current energy economic framework - for each option to use renewable energies the state and looming trends are analyzed. [German] Obwohl die Notwendigkeit zur Dekarbonisierung unserer globalen Wirtschaft und damit insbesondere der Energiebereitstellung zur Begrenzung des globalen Temperaturanstiegs international unstrittig ist, hat die deutsche Politik im Jahr 2014 im Vergleich zu den Vorjahren deutlich weniger zur Erreichung dieses Zieles beigetragen. Der Ausbau der Stromerzeugung aus erneuerbaren Energien im Stromsektor wurde deutlich verlangsamt; und im Waerme- und Mobilitaetsbereich wurden keine neuen Impulse in Bezug auf regenerative Energien gesetzt. Zusaetzlich erschwert ein drastisch gefallener Rohoelpreis die verstaerkte Nutzung des erneuerbaren Energieangebots. Ausgehend von diesen im Vergleich zu den Vorjahren verschlechterten Rahmenbedingungen werden nachfolgend die Entwicklungen in Deutschland des Jahres 2014 im Strom-, Waerme- und Transportsektor fuer den Bereich der erneuerbaren Energien aufgezeigt.

    1993-01-01

    Today, 111 nuclear power plants provide over 20 percent of the electrical energy generated in the United States. The operating license of the oldest operating plant will expire in 2003, one-third of the existing operating licenses will expire by 2010 and the newest plant's operating license will expire in 2033. The National Energy Strategy (NES) prepared by the Department of Energy (DOE) assumes that 70 percent of the current operating plants will continue to operate beyond their current license expiration. Power from current operating plants can assist in ensuring an adequate, diverse, and environmentally acceptable energy supply for economic growth and improved U.S. competitiveness. In order to preserve this energy resource, three major tasks must be successfully completed: (1) establishment of regulations, technical standards, and procedures for the preparation and review of License Renewal Applications (LRAs); (2) development of technical criteria and bases for monitoring, refurbishing or replacing plant equipment; and (3) demonstration of the regulatory process by a plant obtaining a renewed license. Since 1986, the DOE has been working with the nuclear industry and the Nuclear Regulatory Commission (NRC) to establish and demonstrate the option to extend the life of a nuclear power plant by renewing the operating license. The Monticello Lead Plant demonstration project was initiated in September 1988, following the Pilot Plant studies. This paper is primarily focused on the status and insights gained from the Northern States Power Company (NSP) Monticello Lead Plant demonstration project. The following information is included: (1) Current Status - Monticello License Renewal Application; (2) Economic Analysis; (3) License Renewal Regulatory Uncertainty Issues; (4) Key Decisions; (5) Management Structure; (6) Technical and Licensing Perspective; (7) NRC Interactions; (8) Summary

  7. Renewables for sustainable village power

    1997-03-01

    It is estimated that two billion people live without electricity and its services. In addition, there is a sizeable number of rural villages that have limited electrical service, with either part-day operation by diesel gen-sets or partial electrification (local school or community center and several nearby houses). For many villages connected to the grid, power is often sporadically available and of poor quality. The U.S. National Renewable Energy Laboratory (NREL) in Golden, Colorado, has initiated a program to address these potential electricity opportunities in rural villages through the application of renewable energy (RE) technologies. The objective of this program is to develop and implement applications that demonstrate the technical performance, economic competitiveness, operational viability, and environmental benefits of renewable rural electric solutions, compared to the conventional options of line extension and isolated diesel mini-grids. These four attributes foster sustainability; therefore, the program is entitled Renewables for Sustainable Village Power (RSVP). The RSVP program is a multi-technology, multi-application program composed of six activities, including village applications development, computer model development, systems analysis, pilot project development, technical assistance, and Internet-based village power project data base. While the current program emphasizes wind, photovoltaics (PV), and their hybrids with diesel gen-sets, micro-hydro and micro-biomass technologies may be integrated in the future. NREL's RSVP team is currently involved in rural electricity projects in thirteen countries, with U.S., foreign, and internationally based agencies and institutions. The integration of the technology developments, institutional experiences, and the financial solutions for the implementation of renewables in the main line rural electrification processes in both the developing world and remote regions of the developed world is the goal

    Resveratrol (RSV) has been shown to affect the differentiation of several types of stem cells, while the detailed mechanism is elusive. Here, we aim to investigate the function of RSV in self-renewal of mouse embryonic stem cells (ESCs) and the related mechanisms. In contrast with its reported roles, we found unexpectedly that differentiated ESCs or iPSCs treated by RSV would not show further differentiation, but regained a naïve pluripotency state with higher expressions of core transcriptional factors and with the ability to differentiate into all three germ layers when transplanted in vivo. In accordance with these findings, RSV also enhanced cell cycle progression of ESCs via regulating cell cycle-related proteins. Finally, enhanced activation of JAK/STAT3 signaling pathway and suppressed activation of mTOR were found essential in enhancing the self-renewal of ESCs by RSV. Our finding discovered a novel function of RSV in enhancing the self-renewal of ESCs, and suggested that the timing of treatment and concentration of RSV determined the final effect of it. Our work may contribute to understanding of RSV in the self-renewal maintenance of pluripotent stem cells, and may also provide help to the generation and maintenance of iPSCs in vitro. J. Cell.

    2017-07-01

    The EurObserv'ER policy profiles give a snapshot of the renewable energy policy in the EU Member States. In Slovenia, electricity from renewable sources is promoted through a feed-in tariff (so called 'guaranteed purchase') and a premium tariff (so called 'operating premium'), both granted through a tender procedure. Renewable energy sources for heating purposes are promoted mainly through loans on concessional terms and subsidies. The main incentive for renewable energy use in transport are tax exemptions and subsidies

    As many jurisdictions move towards more retributive measures as a means to address public discontent with crime, a parallel movement has developed in regard to restorative justice. This article presents three restorative initiatives currently in use in Canada. Each initiative addresses offender behavior and community engagement at a different point in the justice continuum. The use of Sentencing Circles is an example of how restorative justice principles can be instituted at the front end, prior to an offender becoming lodged in the system. The Restorative Justice Options to Parole Suspension project demonstrates how community engagement can assist in preventing offenders from being returned to the system once they have achieved conditional release. The Circles of Support and Accountability project has enlisted the support of professionally supported volunteers in the community reintegration of high-risk sexual offenders. These initiatives are presented within a framework of effective correctional interventions and increased empowerment for a variety of stakeholders. Copyright 2002 John Wiley & Sons, Ltd.

    Recently, the importance of renewable energy sources has increased significantly as climate change has become an important long term threat to global ecosystems and the world economy. In the face of increased concern about climate change and high fossil fuel costs together with a reduction in the primary energy sources such as oil, natural gas and coal, alternative energy sources (renewables) are increasingly needed to respond to the threat of climate change and growing energy demand in the world. Recent developments in Turkey, such as the liberalization of the electricity market and improvements in the renewable legislations, have accelerated the growth process and investment opportunities in the field of renewable energy. Turkey′s naturally endowed potential for renewables, such as solar, geothermal and wind, also accompanied these developments and attracted world attention to this market. In Turkey, renewable energy sources have gained great importance in the last decades due to growing energy demand and incentive policies which foster the utilization of renewable energy sources. This study aims to explore the availability and potential of renewable energy sources in Turkey and discuss the government policies and economic aspects. - highlights: • Turkey′s potential for renewable energy has attracted world attention. • Turkey has specific energy objectives in promoting renewable energy. • This paper evaluates recent incentives for renewable energy in Turkey. • Incentives in Turkey have led to more investment in renewable energy generation

    The National Atomic Energy Commission (CNEA) started its activities 50 years ago and obtained significant results. At the present time, the CNEA is defined as an Institution of research and development in the nuclear field. It is also responsible for the management of radioactive wastes and the dismantling of nuclear and radioactive facilities. Mining and milling activities have been carried out during the past 40 years and at present the CNEA is undertaking the Uranium Mining Environmental Restoration Project (PRAMU). The aim of this project is to restore the environment as much as is possible in all places where uranium mining and milling activities were developed when taking into consideration both economic and technical reality. First, the characteristics of the problems in each site are determined through appropriate studies which identify the existing or potential impacts, the possible pathways of contamination, etc. The sites being studied are: MALARGUE (Mendoza Province), CORDOBA (Cordoba Province), LOS GIGANTES (Cordoba Province), HUEMUL (Mendoza Province), PICHINAN (Chubut Province), TONCO (Salta Province), LA ESTELA (San Luis Province), LOS COLORADOS (La Rioja Province). PRAMU seeks to improve the current conditions of the tailings deposits and mines and to ensure the long term protection of people and the environment. The CNEA is required to comply with all legislation that is in force and is under the control of various national, provincial and local State institutions. The main objectives of the project for the various sites are: (a) Malargue site: to implement the actions necessary for environmental restoration and management of the tailings derived from the uranium ores processed in the industrial plant; (b) Cordoba and Los Gigantes sites: to design, engineer and execute the activities required for closure of the sites; (c) Other sites (Huemul, Pichinan, Tonco, La Estela, Los Colorados): to develop an environmental evaluation and, on the basis of

    The study's key objectives, as set by the Renewables Advisory Board, the Carbon Trust and DTI, are as follows: To undertake a forward renewables capacity mapping exercise derived from the generation companies' investment plans to 2010, and if the capacity mapping exercise indicates that the planned level of activity is unlikely to meet the 2010 target, to devise and consider a small number of scenarios whereby the 10% target could be achieved; To determine how the transmission and distribution networks need to evolve to enable the Government's 2010 target of 10% of electricity supplied from renewable sources and the aspiration to double that percentage; To investigate the network issues regarding the intermittent nature of renewable generation and the characterisation of renewable generation with regard to grid code compliance; To provide insights into the actions and the stepping stones required between now and 2020 for the key decisions and investments relating to the transformation of the transmission and distribution network, and those issues likely to affect the rate of progress toward the targets. The study also analyses whether there are potential network impacts on renewables expansion from a simultaneous expansion of the UK's CHP capacity to meet the Government target of 10GW of CHP by 2010. The study (which was largely completed ahead of the Government's announcement on extension of the Renewables Obligation Order to 2015, and the raising of the renewables target to 15% of electricity sales by 2015) has found that based on business plans, developers can meet about 72% of the 2010 target by 20061. The Government's announcement has been welcomed by the renewables community and is expected to give added confidence to developers and investors that the Government is intent on creating a long term stable regime to incentivise investment in renewable energy technologies. However, in parallel with tackling what was a decline in

  13. Regulation - renewable energies finally liberated?

    International Nuclear Information System (INIS)

    Blosseville, Thomas

    2016-01-01

    Within the context defined by the new French policy for energy transition, notably in terms of share of renewable energies in final energy consumption, France seems to be somehow late in the development of these energies: about 1 GW of wind energy are installed each year when the expected pace would be 1,5 GW, and the photovoltaic market is shrinking. As the legal context is important, this article proposes an overview of the evolution of the French policy during the last four years which started with interesting measures. Recently, the government showed its will to liberate renewable energies from several constraints. Some legal procedures tend to slow down the development. Some advances could therefore be made, for example to make rules less complex and numerous. The different situations of the wind and biogas sectors are evoked, as well as new opportunities created by a new decree on investment planning

  14. Are renewable energies too expensive?

    International Nuclear Information System (INIS)

    2015-01-01

    As hydroelectricity is known to be profitable, and as biomass displayed good results when used for heating buildings, the issue of the cost of electricity produced by wind and photovoltaic energies is still a matter of debate. This article outlines how to take different factors into account to assess a discount rate. These factors are location which determines wind and sun resource, the future prices of fossil energies, rates of interest, and so on. It indicates that ground based wind and solar farms now have a kWh cost which is close to that of fossil energies, and lower than that of nuclear energy when taking investment and operation cost into account. The production cost of renewable energies has been dramatically reduced during the last years and this trend will probably continue during the years to come. Thus, the article states that a 100 per cent renewable mix seems possible for France by 2050 without significant over-costs

    Our current fossil-fuel-based system is causing potentially catastrophic changes to our planet. The quest for renewable, nonpolluting sources of energy requires us to understand, predict, and ultimately control matter and energy at the electronic, atomic, and molecular levels. Light-source facilities - the synchrotrons of today and the next-generation light sources of tomorrow - are the scientific tools of choice for exploring the electronic and atomic structure of matter. As such, these photon-science facilities are uniquely positioned to jump-start a global revolution in renewable and carbonneutral energy technologies. In these pages, we outline and illustrate through examples from our nation's light sources possible scientific directions for addressing these profound yet urgent challenges.

    2015-04-01

    Renewable energy utilization in transportation (RES-T) is a long way behind its utilization in power (RES-E) and heat (RES-H) sectors. International and national environmental policies have recently given a lot of emphasis on this problem. For that reason information is sought on how to implement solutions both politically and technologically. As Sweden is a global leader in this area, it can provide valuable examples. In 2012 Sweden became the first country to reach the binding requirement of the European Union for at least 10 % share for renewable energy in transport energy consumption. But qualitative development has been even stronger than quantitative. Among the success stories behind qualitative progress, most noteworthy are those created by innovative municipal policies. By 2030 Sweden aims to achieve fossil fuel independent road transport system and by 2050 completely carbon neutral transport system in all modes of transport.

  9. Endogenous production of fibronectin is required for self-renewal of cultured mouse embryonic stem cells.

    Science.gov (United States)

    Hunt, Geoffrey C; Singh, Purva; Schwarzbauer, Jean E

    2012-09-10

    Pluripotent cells are attached to the extracellular matrix (ECM) as they make cell fate decisions within the stem cell niche. Here we show that the ubiquitous ECM protein fibronectin is required for self-renewal decisions by cultured mouse embryonic stem (mES) cells. Undifferentiated mES cells produce fibronectin and assemble a fibrillar matrix. Increasing the level of substrate fibronectin increased cell spreading and integrin receptor signaling through focal adhesion kinase, while concomitantly inducing the loss of Nanog and Oct4 self-renewal markers. Conversely, reducing fibronectin production by mES cells growing on a feeder-free gelatin substrate caused loss of cell adhesion, decreased integrin signaling, and decreased expression of self-renewal markers. These effects were reversed by providing the cells with exogenous fibronectin, thereby restoring adhesion to the gelatin substrate. Interestingly, mES cells do not adhere directly to the gelatin substrate, but rather adhere indirectly through gelatin-bound fibronectin, which facilitates self-renewal via its effects on cell adhesion. These results provide new insights into the mechanism of regulation of self-renewal by growth on a gelatin-coated surface. The effects of increasing or decreasing fibronectin levels show that self-renewal depends on an intermediate level of cell-fibronectin interactions. By providing cell adhesive signals that can act with other self-renewal factors to maintain mES cell pluripotency, fibronectin is therefore a necessary component of the self-renewal signaling pathway in culture.

    Two restoration trials involving four oak species have been implemented as part of a larger restoration program for Catalina Island. In 1997 the Catalina Island Conservancy began an active program of restoration after 50 years of ranching and farming activities on the island. The restoration program includes removing feral goats and pigs island-wide and converting 80...

  15. Renewable Energy Policy Fact sheet - Ireland

    2017-09-01

    The EurObserv'ER policy profiles give a snapshot of the renewable energy policy in the EU Member States. With Ireland's current 'trajectory' of renewable energy growth, it is likely to slightly fall short of its 2020 nationally binding renewable energy target. Ireland initiated a 'moratorium' on its REFIT (Renewable Energy Feed-in Tariff) support scheme in December 2015, with the aim of introducing a revised scheme in 2017 in line with market developments. Grants and tax relief remain in place for renewable heat promotion. An Offshore Renewable Energy Development Plan (OREDP) was introduced in 2014, which sets out Government policy in relation to the sustainable development of Ireland's abundant offshore renewable energy resource

    This project examines renewable energy deployment in the United States using a version of the GCAM integrated assessment model with detailed a representation of renewables, the GCAM-RE. Electricity generation was modeled in four generation segments and 12-subregions. This level of regional and sectoral detail allows a more explicit representation of renewable energy generation. Wind, solar thermal power, and central solar PV plants are implemented in explicit resource classes with new intermittency parameterizations appropriate for each technology. A scenario analysis examines a range of assumptions for technology characteristics, climate policy, and long-distance transmission. We find that renewable generation levels grow over the century in all scenarios. As expected, renewable generation increases with lower renewable technology costs, more stringent climate policy, and if alternative low-carbon technology are not available. The availability of long distance transmission lowers policy costs and changes the renewable generation mix.

  17. Renewable energy - an attractive marketing proposition

    The Global Utilities arm of international business consultants PriceWaterhouseCoopers (PWC) has provided a unique insight into the investment plans of Australian utilities regarding renewable energy. PWC has released the findings of a survey of electricity generators and retailers that neatly illustrates the risks and opportunities facing corporations liable under the mandatory renewable energy targets (MRET). Probably the most revealing finding of the PWC report- 'The Future of Australian Renewable Energy' was that the majority of respondents have not yet formulated a comprehensive renewable energy strategy aimed at meeting their obligations under MRET, or maximising the benefit of renewable energy certificates (RECs) produced. Notably, the majority of those surveyed believed that the strongest incentives for investing in new renewable energy generation was the company's 'green image'. In contrast investment characteristics such as low risk returns, the achievement of cost efficiencies or attractive revenue streams were not critical reasons for investing in renewable generation

    Renewable energy can become the major energy supply option in low-carbon energy economies. Disruptive transformations in all energy systems are necessary for tapping widely available renewable energy resources. Organizing the energy transition from non-sustainable to renewable energy is often described as the major challenge of the first half of the 21st century. Technological innovation, the economy (costs and prices) and policies have to be aligned to achieve full renewable energy potentials, and barriers impeding that growth need to be removed. These issues are also covered by IPCC's special report on renewable energy and climate change to be completed in 2010. This article focuses on the interrelations among the drivers. It clarifies definitions of costs and prices, and of barriers. After reviewing how the third and fourth assessment reports of IPCC cover mitigation potentials and commenting on definitions of renewable energy potentials in the literature, we propose a consistent set of potentials of renewable energy supplies.

    In recent years, sociological examinations of genetics, therapeutic cloning, neuroscience and tissue engineering have suggested that 'life itself' is currently being transformed through technique with profound implications for the ways in which we understand and govern ourselves and others...... in much the same way that mortality rates, life expectancy or morbidity rates can. By analysing the concrete ways in which human progress has been globally measured and taxonomised in the past two centuries or so, I will show how global stratifications of countries according to their states...
