Globalization of the economy will probably coincide with more transport, as a result of which the environmental burden will increase. Thus, the Kyoto standards will be difficult to realize. Based on four economic scenarios with different levels of globalization insight is gained into the possible consequences of future developments (economic development, investment, consumption, (regional) specializations, and trade up to 2020) in the transportation sector, focusing on the Netherlands. Those developments have been made concrete by means of the Worldscan model, developed by the Netherlands Bureau for Economic Policy Analysis (CPB). 8 refs.

Biogenesis of mitochondrial β-barrel proteins requires two preprotein translocases, the general translocase of the outer membrane (TOM) and the sorting and assembly machinery (SAM). TOM and SAM form a supercomplex that promotes transfer of β-barrel precursors. The SAM core complex contains the channel protein Sam50, which cooperates with Sam35 in precursor recognition, and the peripheral membrane protein Sam37. The molecular function of Sam37 has been unknown. We report that Sam37 is crucial for formation of the TOM-SAM supercomplex. Sam37 interacts with the receptor domain of Tom22 on the cytosolic side of the mitochondrial outer membrane and links TOM and SAM complexes. Sam37 thus promotes efficient transfer of β-barrel precursors to the SAM complex. We conclude that Sam37 functions as a coupling factor of the translocase supercomplex of the mitochondrial outer membrane. © 2015 Wenz et al.

Pla-García, J.; Rafkin, S. C.

2017-12-01

The aim of this work is to establish the amount of mixing during all martian seasons to test whether CH4 releases inside or outside of Gale crater are consistent with MSL-SAM observations. Several modeling scenarios were configured, including instantaneous and steady releases, both inside and outside the crater. A simulation to mimic the 2003 Earth-based detections (Mumma et al. 2009 or M09) was also performed. In the instantaneous release inside Gale experiments, Ls270 was shown to be the faster mixing season when air within and outside the crater was well mixed: all tracer mass inside the crater is diluted after just 8 hours. The mixing of near surface crater air with the external environment in the rest of the year is potentially rapid but slower than Ls270.In the instantaneous release outside Gale (NW) experiment, in just 12 hours the CH4 that makes it to the MSL landing location is diluted by six orders of magnitude. The timescale of mixing in MRAMS experiments is on the order of 1 sol regardless of season. The duration of the CH4 peak observed by SAM is 100 sols. Therefore there is a steady release inside the crater, or there is a very large magnitude steady release outside the crater. In the steady release Gale experiments, CH4 flux rate from ground is 1.8 kg m-2 s-1 (derived from Gloesener et al. 2017 clathrates fluxes) and it is not predictive. In these experiments, 200 times lower CH4 values detected by SAM are modeled around MSL location. There are CH4 concentration variations of orders of magnitude depending on the hour, so timing of SAM measurements is important. With a larger (but further away) outside crater release area compared to inside, similar CH4 values around MSL are modeled, so distance to source is important. In the steady experiments mimicking M09 detection release area, only 12 times lower CH4 values detected by SAM are modeled around MSL. The highest value in the M09 modeled scenario (0.6 ppbv) is reached in Ls270. This value is the

Urban landscape of Okazaki in Kyoto

Full Text Available Kyoto has been the capital of Japan from 794 until when the capital has moved in 1868 to Tokyo with the end of Tokugawa Shoguns and the beginning of the Meiji Restoration. The loss of the seat of government was a shock to citizens of Kyoto as the city had been the Imperial and Cultural center of the nation for over 1.000 years. The combination of the court and the great temples had enlivened and enriched the life of the city. At the beginning of the founding of the capital, in the Heian period (794-1185 to east of Kyoto, was built a noble and religious place. This area is Okazaki. Here the Emperor Kammu (736-805 had created the city of Heian-kyo (Kyoto in 794. This area was full of Temples and Shrines. Only in the Edo period (1603-1867 Okazaki area assumed the role of suburban agricultural zone which provided the food production to the urban habitants. But after the Meiji Restoration (1868-1912, the role of Okazaki area changes completely. In 1885, Kyoto prefecture started the great public canalization project as the water supply between Kyoto and Otsu of Shiga prefecture. Kyoto prefecture also planed the industrial district construction in Okazaki area. From the late nineteenth century Okazaki area became a symbol of the modernization of Kyoto city. This contribution intends to analyze the urban landscape composed of the different styles of architecture especially constructed after the Meiji period (1868-1912. Tangible and intangible signs remained as modern gardens, significant museums and cultural institutions among the ancient temples provide opportunities to reflect on the important role of suburban area of the historic city. These studies are supported by archival documents and by current measures and policies for landscape conservation by Kyoto Municipality.

The Kyoto Protocol Emissions Trading Mechanisms - A Model for financing future nuclear development in Romania

International Nuclear Information System (INIS)

Purica, Ionut; John Saroudis

2001-01-01

At the beginning of 2001 Romania ratified the Kyoto Protocol (Law 3/2001) thus becoming the first European country to do so. The mechanisms of the Kyoto Protocol are now opening new ways to sponsor the financing of nuclear projects. In May 2001 Societatea Nationala Nuclearoelectrica S.S. (SNN) and Atomic Energy of Canada Limited and ANSALDO of Italy signed a contract to complete the second CANDU unit at Cernavoda thus giving a new momentum to the nuclear program in Romania. The Government of Romania has indicated its desire to proceed with the completion of the other units on the Cernavoda site and is open to explore every potential financing mechanism to make this a reality. Although the Kyoto Protocol was not ratified by those countries that have the greatest need to reduce emissions, a market for emissions trading has developed, Canada being one of the important players in this market. Since the emission reduction per dollar invested in the Romanian nuclear program would bring much more reduction than the marginal reduction per dollar invested in environmental protection programs in Canada, where the saturation effect is already taking place, we consider that the application of the Kyoto Protocol mechanisms represents a realistic source for a sustainable cooperation of the two countries. This trend is in line with the latest activities of the International Atomic Energy Agency (IAEA). This paper analyzes the impact that the use of emissions credits would have on a typical financing scheme for a future CANDU project in Romania given the present situation and also proposes a model for the structure of the emissions trade that would generate a source of funding for the project. The conclusion is that there is real potential in using Kyoto Protocol mechanisms for financing nuclear development with benefits for both Romania and Canada. (authors)

Carbon Sequestered, Carbon Displaced and the Kyoto Context

Marland, G.; Schlamadinger, B.

The integrated system that embraces forest management, forest products, and land-use change impacts the global carbon cycle - and hence the net emission of the greenhouse gas carbon dioxide - in four fundamental ways. Carbon is stored in living and dead biomass, carbon is stored in wood products and landfills, forest products substitute in the market place for products made from other materials, and forest harvests can be used wholly or partially to displace fossil fuels in the energy sector. Implementation of the Kyoto Protocol to the United Nations Framework Convention on Climate Change would result in the creation of international markets for carbon dioxide emissions credits, but the current Kyoto text does not treat all carbon identically. We have developed a carbon accounting model, GORCAM, to examine a variety of scenarios for land management and the production of forest products. In this paper we explore, for two simple scenarios of forest management, the carbon flows that occur and how these might be accounted for under the Kyoto text. The Kyoto protocol raises questions about what activities can result in emissions credits, which carbon reservoirs will be counted, who will receive the credits, and how much credit will be available? The Kyoto Protocol would sometimes give credits for carbon sequestered, but it would always give credits when fossil-fuel carbon dioxide emissions are displaced

Is Kyoto Fatally Flawed? An Analysis with MacGEM

International Nuclear Information System (INIS)

Eyckmans, J.; Van Regemorter, D.; Van Steenberghe, V.

2002-06-01

In this paper we present some numerical simulations with the MacGEM model to evaluate the consequences of the recent Marrakesh agreements and the defection of the USA for the Kyoto Protocol. MacGEM is a global marginal abatement cost model for carbon emissions from fossil fuel use based on the GEM-E3-World general equilibrium. Nonparticipation of the USA causes the equilibrium carbon price in Annex B countries to fall by approximately 50% since an important share of permit demand falls out. Carbon sinks enhancement activities enable Parties to fulfil their reduction commitment at lower compliance costs and cause the equilibrium permit price to decrease by 40%. Finally, it is shown that the former Soviet Union and central European countries have substantial monopoly power in the Kyoto carbon permit market. We conclude that the recent accords have eroded completely the Kyoto Protocol's emission targets but that they have the merit to have saved the international climate change negotiation framework

The lipid phosphatase Ship2 represents a drug discovery target for the treatment of different diseases, including cancer. Its C-terminal sterile alpha motif domain (Ship2-Sam) associates with the Sam domain from the EphA2 receptor (EphA2-Sam). This interaction is expected to mainly induce pro-oncogenic effects in cells therefore, inhibition of the Ship2-Sam/EphA2-Sam complex may represent an innovative route to discover anti-cancer therapeutics. In the present work, we designed and analyzed several peptide sequences encompassing the interaction interface of EphA2-Sam for Ship2-Sam. Peptide conformational analyses and interaction assays with Ship2-Sam conducted through diverse techniques (CD, NMR, SPR and MST), identified a positively charged penta-amino acid native motif in EphA2-Sam, that once repeated three times in tandem, binds Ship2-Sam. NMR experiments show that the peptide targets the negatively charged binding site of Ship2-Sam for EphA2-Sam. Preliminary in vitro cell-based assays indicate that -at 50 µM concentration- it induces necrosis of PC-3 prostate cancer cells with more cytotoxic effect on cancer cells than on normal dermal fibroblasts. This work represents a pioneering study that opens further opportunities for the development of inhibitors of the Ship2-Sam/EphA2-Sam complex for therapeutic applications.

Dosimetric comparison of the specific anthropomorphic mannequin (SAM) to 14 anatomical head models using a novel definition for the mobile phone positioning

This paper presents new definitions for obtaining reproducible results in numerical phone dosimetry. Numerous numerical dosimetric studies have been published about the exposure of mobile phone users which concluded with conflicting results. However, many of these studies lack reproducibility due to shortcomings in the description of the phone positioning. The new approach was tested by two groups applying two different numerical program packages to compare the specific anthropomorphic mannequin (SAM) to 14 anatomically correct head models. A novel definition for the positioning of mobile phones next to anatomically correct head models is given along with other essential parameters to be reported. The definition is solely based on anatomical characteristics of the head. A simple up-to-date phone model was used to determine the peak spatial specific absorption rate (SAR) of mobile phones in SAM and in the anatomically correct head models. The results were validated by measurements. The study clearly shows that SAM gives a conservative estimate of the exposure in anatomically correct head models for head only tissue. Depending on frequency, phone position and head size the numerically calculated 10 g averaged SAR in the pinna can be up to 2.1 times greater than the peak spatial SAR in SAM. Measurements in small structures, such as the pinna, will significantly increase the uncertainty; therefore SAM was designed for SAR assessment in the head only. Whether SAM will provide a conservative value for the pinna depends on the pinna SAR limit of the safety standard considered

We present the program package GoSam which is designed for the automated calculation of one-loop amplitudes for multi-particle processes in renormalisable quantum field theories. The amplitudes, which are generated in terms of Feynman diagrams, can be reduced using either D-dimensional integrand-level decomposition or tensor reduction. GoSam can be used to calculate one-loop QCD and/or electroweak corrections to Standard Model processes and offers the flexibility to link model files for theories Beyond the Standard Model. A standard interface to programs calculating real radiation is also implemented. We demonstrate the flexibility of the program by presenting examples of processes with up to six external legs attached to the loop. (orig.)

Three distinct classes of S-adenosyl-L-methionine (SAM)-responsive riboswitches have been identified that regulate bacterial gene expression at the levels of transcription attenuation or translation inhibition. The SMK box (SAM-III) translational riboswitch has been identified in the SAM synthetase gene in members of the Lactobacillales. Here we report the 2.2-{angstrom} crystal structure of the Enterococcus faecalis SMK box riboswitch. The Y-shaped riboswitch organizes its conserved nucleotides around a three-way junction for SAM recognition. The Shine-Dalgarno sequence, which is sequestered by base-pairing with the anti-Shine-Dalgarno sequence in response to SAM binding, also directly participates in SAM recognition. The riboswitch makes extensive interactions with the adenosine and sulfonium moieties of SAM but does not appear to recognize the tail of the methionine moiety. We captured a structural snapshot of the SMK box riboswitch sampling the near-cognate ligand S-adenosyl-L-homocysteine (SAH) in which SAH was found to adopt an alternative conformation and fails to make several key interactions.

RimO, a radical-S-adenosylmethionine (SAM) enzyme, catalyzes the specific C 3 methylthiolation of the D89 residue in the ribosomal S 12 protein. Two intact iron-sulfur clusters and two SAM cofactors both are required for catalysis. By using electron paramagnetic resonance, Mössbauer spectroscopies, and site-directed mutagenesis, we show how two SAM molecules sequentially bind to the unique iron site of the radical-SAM cluster for two distinct chemical reactions in RimO. Our data establish that the two SAM molecules bind the radical-SAM cluster to the unique iron site, and spectroscopic evidence obtained under strongly reducing conditions supports a mechanism in which the first molecule of SAM causes the reoxidation of the reduced radical-SAM cluster, impeding reductive cleavage of SAM to occur and allowing SAM to methylate a HS - ligand bound to the additional cluster. Furthermore, by using density functional theory-based methods, we provide a description of the reaction mechanism that predicts the attack of the carbon radical substrate on the methylthio group attached to the additional [4Fe-4S] cluster.

Carbon credits after Kyoto

1998-01-01

In the Kyoto Protocol to the FCCC three different forms of GHG emission reduction titles through market-based international cooperation are defined: emission reduction units under Article 6; certified emission reductions in the framework of the Clean Development Mechanism (CDM) under Article 12; and emissions trading under Article 17. Although defined under different Articles in the Protocol, it seems reasonable to assume that the three mechanisms will not operate separately. After CoP3 the author registered several comments, opinions and concerns related to the flexibility provisions under the Kyoto Protocol

Application of the Kyoto Mechanisms in Finland's climate policy. Report of the Finnish Committee on the Kyoto mechanisms

International Nuclear Information System (INIS)

2001-01-01

By the flexible mechanisms under the Kyoto Protocol are meant project-specific Joint Implementation, JI, intended for emissions reduction in the industrialised countries and the Clean Development Mechanism, CDM, designed for emissions reduction in the developing countries. Joint Implementation Projects can be found particularly in the economies-in-transition The flexible mechanisms under the Protocol also include Emissions Trading, ET, which States - and according to the view of several parties, enterprises, too - can conduct subject to rules to be later agreed upon in connection with emissions rights The international climate negotiations on the Kyoto Protocol and on drafting more detailed rules on the use of the mechanisms are still pending. In fact, the Working Group thinks that the uncertainties so far connected with the flexible mechanisms will lead to a situation in which the national climate policy must, at this stage, be primarily based on domestic reduction measures. Even if Finland were prepared to meet her climate policy obligations through domestic measures, there is, in the Working Group's opinion, skill reason to continue the preparations for the possibilities of using the Kyoto flexible mechanisms, too. The prime goal of the flexible mechanisms is an internationally cost-efficient climate policy, which creates the preconditions for the gradual tightening of emission limitations in a manner that will hinder economic and other societal activity as little as possible. Thus the flexible mechanisms can become more important during later commitment periods. According to model calculations, using the mechanisms would probably be inexpensive compared to the domestic emission reduction measures. It seems that the international markets for assigned amount units obtained through the use of the mechanisms would be big enough in view of the relatively limited immediate needs of the Finnish Climate Policy.

Benchmark Simulation of Natural Circulation Cooling System with Salt Working Fluid Using SAM

Ahmed, K. K.; Scarlat, R. O.; Hu, R.

2017-09-03

Liquid salt-cooled reactors, such as the Fluoride Salt-Cooled High-Temperature Reactor (FHR), offer passive decay heat removal through natural circulation using Direct Reactor Auxiliary Cooling System (DRACS) loops. The behavior of such systems should be well-understood through performance analysis. The advanced system thermal-hydraulics tool System Analysis Module (SAM) from Argonne National Laboratory has been selected for this purpose. The work presented here is part of a larger study in which SAM modeling capabilities are being enhanced for the system analyses of FHR or Molten Salt Reactors (MSR). Liquid salt thermophysical properties have been implemented in SAM, as well as properties of Dowtherm A, which is used as a simulant fluid for scaled experiments, for future code validation studies. Additional physics modules to represent phenomena specific to salt-cooled reactors, such as freezing of coolant, are being implemented in SAM. This study presents a useful first benchmark for the applicability of SAM to liquid salt-cooled reactors: it provides steady-state and transient comparisons for a salt reactor system. A RELAP5-3D model of the Mark-1 Pebble-Bed FHR (Mk1 PB-FHR), and in particular its DRACS loop for emergency heat removal, provides steady state and transient results for flow rates and temperatures in the system that are used here for code-to-code comparison with SAM. The transient studied is a loss of forced circulation with SCRAM event. To the knowledge of the authors, this is the first application of SAM to FHR or any other molten salt reactors. While building these models in SAM, any gaps in the code’s capability to simulate such systems are identified and addressed immediately, or listed as future improvements to the code.

Controlled surface adhesion of non - pathogenic gram positive strain, Staphylococcus aureus is interesting as a model system due to possible development of respective biosensors for prevention and detection of the pathogenic strain methicillin resistant Staphylococcus aureus (MRSA) and further as a study for bio-machine interfacing. Self Assembled Monolayers (SAM) with engineered surfaces of linear thiols on Au(111) were used as the substrate. Sub cultured S. aureus were used for the analysis. The SAM layered surfaces were dipped in 2 -- 4 Log/ml S. aureus solution. Subsequent surface adhesion at different bacterial dilutions on surfaces will be discussed, and correlated with quantitative and qualitative adhesion properties of bacteria on the engineered SAM surfaces. The bacteria adhered SAM surfaces were investigated using intermittent contact, noncontact, lateral force and contact modes of Atomic Force Microscopy (AFM).

The Kyoto mechanisms and technological innovation

International Nuclear Information System (INIS)

Lund, Henrik

2006-01-01

Climate change response, including the implementation of the Kyoto targets as the first step, calls for technological innovation of future sustainable energy systems. Based on the Danish case, this paper evaluates the type of technological change necessary. During a period of 30 years, Denmark managed to stabilize primary energy supply, and CO 2 emissions decreased by 10%, during a period of 20 years. However, after the introduction of the Kyoto Mechanisms, Denmark has changed its strategy. Instead of continuing the domestic CO 2 emission controls, Denmark plans to buy CO 2 reductions in other countries. Consequently, the innovative technological development has changed. This paper evaluates the character of such change and makes preliminary recommendations for policies to encourage the use of the Kyoto Mechanisms as an acceleration of the necessary technological innovation.

The purpose of this facility is to accept outside demands concerning the application of the research reactor. The building is a two story building, and has the floor area of 901.47 m 2 . There are an exhibition room, a library, and a big lecture room. In the exhibition room, models of the Kyoto University Research Reactor and the Kyoto University Critical Assembly are placed. Various pictures concerning the application of the reactor are on the wall. In the library, people from outside of the Institute can use various books on science. Books for boys and girls are also stocked and used for public use. At the lecture room, various kinds of meeting can be held. (Kato, T.)

From Kyoto to Copenhagen: the carbon markets expansion

International Nuclear Information System (INIS)

Alberola, Emilie; Fages, Emmanuel

2009-01-01

The article examines the development of carbon markets in the world. Such markets are the main economic instrument of the international climate policy established by the Kyoto Protocol in 1997 and are being implemented by most industrialized countries. They are experimented by Europe since 2005 for industrial facilities and since 2008 by industrialized countries under Kyoto. The development of carbon markets will likely continue beyond 2012, when the Kyoto Protocol expires. Their expansion will be largely determined by the future international climate policy to be negotiated in Copenhagen in December 2009 and by the commitment of the largest economies like the United States. The authors describe the emergence of carbon markets, their basic principles and the experience of Kyoto and European markets. Then, they deal with the expected developments beyond 2012

On LAM's and SAM's for Halley's rotation

Science.gov (United States)

Peale, Stanton J.

1992-01-01

Non principal axis rotation for comet Halley is inferred from dual periodicities evident in the observations. The modes where the spin axis precesses around the axis of minimum moment of inertia (long axis mode or LAM) and where it precesses around the axis of maximum moment of inertia (short axis mode or SAM) are described from an inertial point of view. The currently favored LAM model for Halley's rotation state satisfies observational and dynamical constraints that apparently no SAM can satisfy. But it cannot reproduce the observed post perihelion brightening through seasonal illumination of localized sources on the nucleus, whereas a SAM can easily produce post or pre perihelion brightening by this mechanism. However, the likelihood of a LAM rotation for elongated nuclei of periodic comets such as Halley together with Halley's extreme post perihelion behavior far from the Sun suggest that Halley's post perihelion brightening may be due to effects other than seasonal illumination of localized sources, and therefore such brightening may not constrain its rotation state.

The costs of the Kyoto Protocol in the European Union

We estimate reference CO 2 emission projections in the European Union, and quantify the economic impacts of the Kyoto commitment on Member States. We consider the case where each EU member individually meets a CO 2 emissions target, applying a country-wide cap and trade system to meet the target but without trade among countries. We use a version of the MIT Emissions Prediction and Policy Analysis (EPPA) model, here disaggregated to separately include 9 European Community countries and commercial and household transportation sectors. We compare our results with that of four energy-economic models that have provided detailed analyses of European climate change policy. In the absence of specific additional climate policy measures, the EPPA reference projections of carbon emissions increase by 14% from 1990 levels. The EU-wide target under the Kyoto Protocol to the Framework Convention on Climate Change is a reduction in emissions to 8% below 1990 levels. EPPA emissions projections are similar to other recent modeling results, but there are underlying differences in energy and carbon intensities among the projections. If EU countries were to individually meet the EU allocation of the Community-wide carbon cap specified in the Kyoto Protocol, we find using EPPA that carbon prices vary from $91 in the United Kingdom to $385 in Denmark; welfare costs range from 0.6% to 5%

Past and Future of the Kyoto Protocol. Final report

International Nuclear Information System (INIS)

Wijen, F.; Zoeteman, K.

2004-01-01

The present report reflects findings from a study on the realization of and prospects for the Kyoto Protocol. The purpose of the study was (1) to obtain insights into the factors that enabled the realization of the Kyoto Protocol, in particular the interactions among major parties involved; (2) to assess the future opportunities and threats of the Kyoto Protocol, in particular against the backdrop of an increasingly globalised world. The study was conducted from February up to December 2003 by (a) reviewing the literature, especially publications on the negotiation history of the Kyoto process, the social interactions enabling the realization of the Protocol, analyses of strengths and weaknesses, and future climate regimes; (b) conducting a series of interviews with representatives from government, academia, non-governmental organisations, and business, who have been - directly or indirectly - involved in the Kyoto process; (c) internal discussions,brainstorming and analysing the Protocol's strengths and weaknesses, possible future scenarios (including policy options), and the management of a possible failure of the Kyoto Protocol. The present report reflects and integrates the different sources. The first section deals with the past and the present. It discusses how the Kyoto Protocol could be realized despite the divergent interests, reflects on its architecture, and analyses major strengths and weaknesses. In the second section, we present possible future scenarios. We explore how different combinations of domestic and international commitment provide possible realities that national government may face when crafting climate policy. The third section provides an in-depth analysis of the possible event that the Kyoto Protocol fails. We discuss its definition and policy implications. The final section is reserved for overall conclusions and policy recommendations

Analyzing the economic cost of the Kyoto protocol

International Nuclear Information System (INIS)

Khanna, N.

2001-01-01

This paper examines the cost of meeting the Kyoto Protocol commitments under alternative assumptions regarding technology and technical change. Real GDP is modeled as a function of the capital, labor, and energy inputs. The analysis is based on data for 23 Annex 1 countries from 1965 to 1999. Two important results emerge. First, the standard assumption of Hicks neutral technical change and time and scale independent output elasticities is not supported by the data. Second, when technical change is allowed to be biased in favor of the energy and capital inputs, and when the output elasticities vary with the level of factor use and over time, the loss in real GDP due to the Kyoto commitments rises substantially. On average, the loss in real GDP is one and a half times higher than obtained under the standard assumptions. 26 refs

Kyoto : implications for utility regulation

Dunsky, P.

2003-01-01

The author provided a historical perspective of energy use and the role of carbon in the western hemisphere by displaying a series of graphs showing carbon intensity of energy, carbon emissions from energy, and the long path to green power. The 1990s represented a decade of progress. Almost three times as much wind capacity as nuclear capacity was added worldwide in 2001. The main challenge for the 21st century will be to bring under-developed countries into the fold while perpetuating the economic and human progress of the twentieth century. It was emphasized that environmental damage caused by utilities must be reversed. The contemporary context for the Kyoto Protocol was reviewed. Canada's commitment under the Kyoto Protocol is to reduce greenhouse gas emissions by 6 per cent below 1990 levels. The challenge for utility regulators to meet this commitment was examined. The costs are not entirely excessive. Some of the regulatory issues were discussed, namely revising a broad rate making framework, cost recovery and others. The Kyoto compliance plan was also reviewed with reference to internal options, external options, identification of regulatory barriers, and consideration of greenhouse gas credit markets. figs

Progress Report on SAM Reduced-Order Model Development for Thermal Stratification and Mixing during Reactor Transients

This report documents the initial progress on the reduced-order flow model developments in SAM for thermal stratification and mixing modeling. Two different modeling approaches are pursued. The first one is based on one-dimensional fluid equations with additional terms accounting for the thermal mixing from both flow circulations and turbulent mixing. The second approach is based on three-dimensional coarse-grid CFD approach, in which the full three-dimensional fluid conservation equations are modeled with closure models to account for the effects of turbulence.

The majority of climate protection experts believe that the Kyoto Protocol in its present version provides a basis for preventing the climate change from taking on disastrous dimensions. In the meantime however a mainstream of opinion has developed which advocates the establishment of a functioning global climate protection system for the post-Kyoto phase. Kyoto Plus, a global climate certification system, is a concept developed by the author of three expert opinions for the state of Baden-Wuerttemberg which takes the principles of the Kyoto Protocol a step forward while striving to eliminate its weaknesses and which has matured sufficiently to be put into practice. Systems of this or a similar kind could enable Germany to make a decisive additional contribution to global climate protection, as the author stated at the BT Hearing on 23 May 2007.

Hydro in the Kyoto era

Quebec has the best performance in North America in terms of greenhouse gas (GHG) emissions. Unlike neighbouring provinces and states which rely heavily on coal for power generation, Quebec generates 96 per cent of its electricity from hydroelectric power. However, no new dams have been built in the past decade in Quebec due to land disputes with Aboriginal communities and general distrust among many ecologists. It takes about 12 years for a hydroelectric project to come to fruition. For that reason, and in order to capitalize on energy market opportunities, Hydro-Quebec is seriously considering expanding its generating capability beyond the needs of Quebec consumers, with gas-fired thermal generating stations. Environmental groups claim that the proposal to build the Suroit combined-cycle facility near the United States border destroys Quebec's efforts to honour the Kyoto Protocol. Economists argue that it is entirely in the spirit of Kyoto if exports of hydroelectricity or natural gas from Canada to the United States leads to less use of oil or coal. But one energy modeling expert at INRS-Energie et Materiaux claims that Quebec has a moral obligation to develop hydroelectricity for its own use as well as for export purposes, noting that any country with the good fortune to have renewable forms of energy, such as wind and hydro, should develop them to lower world GHG emissions. Quebec has many opportunities to sell hydroelectricity even while domestic demand grows. Hydroelectricity from Quebec should interest some states that have adopted their own GHG reduction standards, despite the U.S. government's refusal to ratify Kyoto. It should also interest Ontario and the Maritimes because they will be trying to reduce emissions from their thermal plants. The current situation does not favour the Kyoto Protocol. Exports of electricity from Quebec have dropped because no new dams have been built in recent years and gas-fired plants are looking more attractive to power

Clean Development Mechanism: Core of Kyoto Mechanism

Kyoto protocol is a foundation for achieving an ultimate goal of UNFCCC, which is to stabilizing greenhouse gas concentration in the air. The clean development system is a core element for successful implementation of Kyoto protocol with other Kyoto mechanisms. While UNFCCC requires a new paradigm changing to sustainable development considering demand and future environment from the past supply-oriented resource consumption, the clean development system will be used as a means of successful establishment of a new paradigm in 21st century. As environmental problem is integrated with economic problem and each country is thriving for securing its own economic benefit in the issue of environmental conservation, Korea should do its best to have both of global environmental conservation and economic benefit for its own. 1 tab.

Setting the stage: Outcome from Kyoto

The commitment of the upstream oil and gas industry to implement actions to help Canadians become more efficient in their use of energy was discussed. The goals of the Rio Framework convention revolved around achieving greenhouse gas emissions reductions in the least costly manner. The industrial sector responded to that challenge through voluntary efforts to reduce greenhouse gases. However, from an industry perspective, the VCR (voluntary challenge registry) performance was inconsistent. While the upstream oil and gas industry participated aggressively, other industrial sectors, particularly the transportation sector, failed to participate. Progress was too slow and too late. The Third Conference of the Parties in Kyoto, resulted in a binding commitment of between 20 and 25 per cent per annum reduction for Canada. Emissions trading among developed countries is also included in the Kyoto Protocols. The speaker considered the reduction commitment of 20 to 25 per cent for Canada unrealistic, and suggested that the Kyoto protocol may be flawed, if only because so many of the details have not been spelled out. The importance of the roles of the federal and provincial governments in enforcing their consultative processes was emphasized. In the view of this speaker and that of the Canadian Association of Petroleum Producers, the biggest disappointments coming out of Kyoto, was the failure to gain meaningful involvement from the developing world. A global effort to reduce emissions cannot be achieved without the participation of the developing countries

Croatia energy planning and Kyoto Protocol

Croatia as an Annex I country of the UN Framework Convention on Climate Change and a country that has pledged in the Annex B of the Kyoto Protocol to reduce its GHG emissions by 5% will have to envisage a new energy strategy. Compared to the energy consumption collapse in some transitional countries, Croatia has passed through a relatively short-term reduction of GHG emissions since 1990 because of higher energy efficiency of its pretransition economy. It is expected that in case of baseline scenario, it will breach the Kyoto target in 2003. Several scenarios of power generation are compared from the point of view of GHG emissions. The cost-effective scenario expects a mixture of coal and gas fired power plants to be built to satisfy the new demand and to replace the old power plants that are being decommissioned. More Kyoto friendly scenario envisages forcing the compliance with the Protocol with measures only in power generation sector by the construction of mainly zero emission generating capacity in the future, while decommissioning the old plants as planned, and is compared to the others from the GHG emissions point of view. The conclusion is that by measures tackling only power generation, it will not be possible to keep GHG emission under the Kyoto target level. The case of including the emissions from Croatian owned power plants in former Yugoslavia is also discussed

The Kyoto Protocol. An economic appraisal

International Nuclear Information System (INIS)

Grubb, M.

2000-05-01

This paper examines the overall economics of the Kyoto Protocol on climate change, in three main parts. The first part explores the structure of the Protocol and how this matches against classical economic criteria of an 'optimal' climate change agreement. This discussion also considers the nature of and reasons for shortcomings, and the prospects for its evolution. Given the various flexibilities in the agreement, the Kyoto Protocol is far more economically efficient in its structure than any previous global environmental agreement. The central conclusion is that, from an economic perspective, the Protocol's structure for industrialised country commitments is as good as could reasonably be expected. The second part of the paper explores more closely the economics of the commitments themselves and how they combine with the various flexibilities, briefly reviewing the available literature and using a simple spreadsheet model of how the commitments might combine with trading mechanisms under a range of assumptions. Flexibility is intrinsic and necessary, but it is argued that the allocations to Russia and Ukraine in particular mean that unlimited flexibility could render the Protocol's commitments weaker in their impacts than is economically desirable to address climate change. It is argued that, should this prove to be the case, access to the large surplus in the transition economies could be used as a control valve to limit the costs of the Protocol to within acceptable limits. Finally, the paper considers the issues of developing country involvement in the Kyoto Protocol, and the Protocol's longer-term impact and evolution, including its impact on technological evolution and dissemination and the evolution of future commitments. It is argued that taking account of such issues critically affects views of the Protocol

The Kyoto embryo collection was begun in 1961 by Dr. Hideo Nishimura. The collection has been continuously developed and currently contains over 44,000 human normal and abnormal specimens. Beginning online in 1997, the internet provided an opportunity to make embryos from the collection widely available for research and educational purposes (http://tiny.cc/Embryo). These embryonic development resources have been continuously published and available from that time until today. Published in Japanese as an Atlas of Embryonic Development. Published online as the Kyoto Human Embryo Visualization Project (http://atlas.cac.med.kyoto-u.ac.jp) and also as the Human Embryo Atlas (http://tiny.cc/Human_Embryo_Atlas). Published now electronically as a digital eBook (http://tiny.cc/Kyoto_Collection_eBook). This new digital format allows incorporation of whole embryo and histology manipulable images, labels, and a linked glossary. New imaging modalities of magnetic resonance imaging (MRI) and episcopic fluorescence image capture (EFIC) can also be easily displayed as animations. For research, the collection specimens and histological sections have been extensively studied and published in several hundred papers, discussed here and elsewhere in this special edition. I will also describe how the Kyoto collection will now form a major partner of a new international embryology research group, the Digital Embryology Consortium (https://human-embryology.org). The digital Kyoto collection will be made available for remote researcher access, analysis, and comparison with other collections allowing new research and educational applications.

Ocean fertilization, carbon credits and the Kyoto Protocol

Science.gov (United States)

Westley, M. B.; Gnanadesikan, A.

2008-12-01

Commercial interest in ocean fertilization as a carbon sequestration tool was excited by the December 1997 agreement of the Kyoto Protocol to the United Nations Convention on Climate Change. The Protocol commits industrialized countries to caps on net greenhouse gas emissions and allows for various flexible mechanisms to achieve these caps in the most economically efficient manner possible, including trade in carbon credits from projects that reduce emissions or enhance sinks. The carbon market was valued at 64 billion in 2007, with the bulk of the trading (50 billion) taking place in the highly regulated European Union Emission Trading Scheme, which deals primarily in emission allowances in the energy sector. A much smaller amount, worth $265 million, was traded in the largely unregulated "voluntary" market (Capoor and Ambrosi 2008). As the voluntary market grows, so do calls for its regulation, with several efforts underway to set rules and standards for the sale of voluntary carbon credits using the Kyoto Protocol as a starting point. Four US-based companies and an Australian company currently seek to develop ocean fertilization technologies for the generation of carbon credits. We review these plans through the lens of the Kyoto Protocol and its flexible mechanisms, and examine whether and how ocean fertilization could generate tradable carbon credits. We note that at present, ocean sinks are not included in the Kyoto Protocol, and that furthermore, the Kyoto Protocol only addresses sources and sinks of greenhouse gases within national boundaries, making open-ocean fertilization projects a jurisdictional challenge. We discuss the negotiating history behind the limited inclusion of land use, land use change and forestry in the Kyoto Protocol and the controversy and eventual compromise concerning methodologies for terrestrial carbon accounting. We conclude that current technologies for measuring and monitoring carbon sequestration following ocean fertilization

NAFTA's shadow hangs over Kyoto's implementation

2007-01-01

The Canadian government recently stated that it will not meet its Kyoto targets by the end of the first period in 2012, and instead proposed a twofold solution to reduce greenhouse gas emissions. The solutions involve the development of a Clean Air Act that will seek a 50 per cent reduction in emissions by 2050; and, participation in negotiations to determine the next steps for the Kyoto Protocol, post-2012. It was noted that as a ratified member of the Kyoto Protocol, Canada is still legally obligated to achieve its reduction requirements. However, as a co-signatory of the North American Free-Trade Agreement (NAFTA), Canada may be impeded from introducing and maintaining GHG reducing initiative since there are elements of NAFTA which may be used to block efforts that are considered discriminatory to trade. Chapter 11 of NAFTA assigns rights to Canadian, American and Mexican private investors to promote investment, ensure equal treatment and protect their investments against discrimination by NAFTA governments other than their own. These rights may challenge independent action by member states to reduce environmental risks. The authors emphasized that in order to avoid the possibility of legal challenges through Chapter 11 of NAFTA, it is important for the Canadian government to address various aspects of the flexibility mechanisms in the Kyoto Protocol. Three of these mechanisms were designed to reduce the financial burden and technological capacity issues associated with mitigating GHG emissions. These include emissions trading system, clean development mechanism, and joint implementation. The authors presented some policy recommendations to avoid future conflict. 26 refs

By means of the Kyoto Mechanisms Joint Implementation, the Clean Development Mechanism and International Emissions Trading it will be possible to produce abroad and trade internationally the greenhouse gas emission reductions needed to satisfy cost-efficiently the respective demand of industrialized countries. The paper analyses options available in the natural gas sector for realizing Joint Implementation and Clean Development Mechanism projects. Furthermore, it examines strategies that might be economically viable for companies operating in the natural gas sector for taking advantage of the Kyoto Mechanisms. (author)

Teleconnection stationarity, variability and trends of the Southern Annular Mode (SAM) during the last millennium

The Southern Annular Mode (SAM) is the leading mode of atmospheric interannual variability in the Southern Hemisphere (SH) extra-tropics. Here, we assess the stationarity of SAM spatial correlations with instrumental and paleoclimate proxy data for the past millennium. The instrumental period shows that temporal non-stationarities in SAM teleconnections are not consistent across the SH land areas. This suggests that the influence of the SAM index is modulated by regional effects. However, within key-regions with good proxy data coverage (South America, Tasmania, New Zealand), teleconnections are mostly stationary over the instrumental period. Using different stationarity criteria for proxy record selection, we provide new austral summer and annual mean SAM index reconstructions over the last millennium. Our summer SAM reconstructions are very robust to changes in proxy record selection and the selection of the calibration period, particularly on the multi-decadal timescale. In contrast, the weaker performance and lower agreement in the annual mean SAM reconstructions point towards changing teleconnection patterns that may be particularly important outside the summer months. Our results clearly portend that the temporal stationarity of the proxy-climate relationships should be taken into account in the design of comprehensive regional and hemispherical climate reconstructions. The summer SAM reconstructions show no significant relationship to solar, greenhouse gas and volcanic forcing, with the exception of an extremely strong negative anomaly following the AD 1257 Samalas eruption. Furthermore, reconstructed pre-industrial summer SAM trends are very similar to trends obtained by model control simulations. We find that recent trends in the summer SAM lie outside the 5-95% range of pre-industrial natural variability.

Full Text Available Samâ‘ in Tasawuf has been a very important element in the dissemination of this spiritual dimension of Islam. Yet, it has received very little both from the practitioners of Tasawuf and its intellectuals. This paper tries to expose this simply in a hope to make it heard in the academic and popular circle. Here, samâ‘ is not only understood as a form of music, as many would do, but also as an art of listening of which music is certainly part. The paper will explore the meaning and definition of this term, putting emphasis on its many-faceted function in the formation and development of one’s soul and spirituality. It is argued that soul is musical and artistic. Using art and music to talk to soul is therefore the proper way and means. The paper will also try to show that samâ‘ is also an indispensable part of spiritual method to reach and know God. Knowledge of God in other words, can be gained through this practice. Hence, samâ‘ is treated not only as a form of entertainment, but also a kind of practical epistemology.

Amine terminated SAMs: Investigating why oxygen is present in these films

Self-assembled monolayers (SAMs) on gold prepared from amine-terminated alkanethiols have long been employed as model positively charged surfaces. Yet in previous studies significant amounts of unexpected oxygen containing species are always detected in amine terminated SAMs. Thus, the goal of this investigation was to determine the source of these oxygen species and minimize their presence in the SAM. The surface composition, structure, and order of amine-terminated SAMs on Au were characterized by X-ray photoelectron spectroscopy (XPS), time-of-flight secondary ion mass spectroscopy (ToF-SIMS), sum frequency generation (SFG) and near edge X-ray absorption fine structure (NEXAFS) spectroscopy. XPS determined compositions of amine-terminated SAMs in the current study exhibited oxygen concentrations of 2.4 ± 0.4 atomic %, a substantially lower amount of oxygen than reported in previously published studies. High-resolution XPS results from the S 2p , C 1s and N 1s regions did not detect any oxidized species. Angle-resolved XPS indicated that the small amount of oxygen detected was located at or near the amine head group. Small amounts of oxidized nitrogen, carbon and sulfur secondary ions, as well as ions attributed to water, were detected in the ToF-SIMS data due to the higher sensitivity of ToF-SIMS. The lack of N-O, S-O, and C-O stretches in the SFG spectra are consistent with the XPS and ToF-SIMS results and together show that oxidation of the amine-terminated thiols alone can only account for, at most, a small fraction of the oxygen detected by XPS. Both the SFG and angle-dependent NEXAFS indicated the presence of gauche defects in the amine SAMs. However, the SFG spectral features near 2865 cm -1 , assigned to the stretch of the methylene group next to the terminal amine unit, demonstrate the SAM is reasonably ordered. The SFG results also show another broad feature near 3200 cm -1 related to hydrogen-bonded water. From this multi-technique investigation it is

This study aimed to evaluate the effectiveness of the MARKAL comprehensive model in the development of coherent medium-term strategies and sound climate protection policies at local level. The local case study (Val d'Agri, Basilicata region, Italy) discusses the possible role of local communities in the achievement of the national objectives derived by the Kyoto Protocol, investigating the traditional sectors responsible for air pollution and providing a full picture of the main energy and material flows. A scenario analysis was performed to analyse the response of the modelled system to the introduction of an exogenous constraint on carbon dioxide (CO 2 ) emissions. The main effects are presented with reference to fuel mix, technology choice, real market prices and reduced costs of competing options. The comparison of the solutions obtained for the different scenarios is useful to point out the effects of the CO 2 constraint on the total system cost and on the emission levels of other atmospheric pollutants. A further multiobjective optimisation was performed to analyse the effects of combined environmental constraints (CO 2 and particulate) on the overall system cost as well as in terms of marginal costs.

A further multiobjective optimisation was performed to analyse the effects of combined environmental constraints (CO{sub 2} and particulate) on the overall system cost as well as in terms of marginal costs.

Picornavirus infection can lead to disruption of nuclear pore traffic, shut-off of cell translation machinery, and cleavage of proteins involved in cellular signal transduction and the innate response to infection. Here, we demonstrated that the FMDV 3C pro induced the cleavage of nuclear RNA-binding protein Sam68 C-terminus containing the nuclear localization sequence (NLS). Consequently, it stimulated the redistribution of Sam68 to the cytoplasm. The siRNA knockdown of Sam68 resulted in a 1000-fold reduction in viral titers, which prompted us to study the effect of Sam68 on FMDV post-entry events. Interestingly, Sam68 interacts with the internal ribosomal entry site within the 5′ non-translated region of the FMDV genome, and Sam68 knockdown decreased FMDV IRES-driven activity in vitro suggesting that it could modulate translation of the viral genome. The results uncover a novel role for Sam68 in the context of picornaviruses and the proteolysis of a new cellular target of the FMDV 3C pro .

Impact of the Kyoto Protocol on the Iberian Electricity Market: A scenario analysis

Reneses, Javier; Centeno, Efraim

2008-01-01

This paper presents an assessment of the impact of the Kyoto Protocol on the Iberian Electricity Market during two periods: the first phase (2005-2007) and the second phase (2008-2012). A market-equilibrium model is used in order to analyze different conditions faced by generation companies. Scenarios involving CO 2 -emission prices, hydro conditions, demand, fuel prices and renewable generation are considered. This valuation will show the significance of CO 2 -emission prices as regards Spanish and Portuguese electricity prices, generation mix, utilities profits and the total CO 2 emissions. Furthermore, the results will illustrate how energy policies implemented by regulators are critical for Spain and Portugal in order to mitigate the negative impact of the Kyoto Protocol. In conclusion, the Iberian electricity system will not be able to reach the Kyoto targets, except in very favorable conditions (CO 2 -emission prices over Euro 15/ton and the implementation of very efficient energy policies)

The environmental agreement may lead to large losses for the oil producers. The Kyoto mechanisms are very important to Norway

International Nuclear Information System (INIS)

1999-01-01

The article presents an economic model study of the implications of an climatic agreement. Two main scenarios are presented: 1) The Kyoto protocol is extended to 2020. 2) All counties ratify a climatic agreement. The conclusions are that the Kyoto protocol may have great effects on the oil and gas markets and large economic consequences for Norway. It is therefore mandatory to extensively use the Kyoto mechanisms such as trade with quotas, common implementation and the green development mechanism

A 2004 view of the Kyoto Protocol

It may not be a household word, but by now the Kyoto Protocol has become a well-known political slogan. It is either ''fundamentally flawed'' (George W. Bush) or it is essential for saving the climate and humanity (Al Gore). There seems to be no in between. The Kyoto Protocol is a treaty to limit (i.e., ration) the use of energy to satisfy the concerns of environmental groups and other believers in global warming catastrophes. This group includes not only certified kooks but also such notables as former Treasury Secretary Paul O'Neill and Sir David King, chief scientific adviser to Her Majesty's government who equates the threat of warming with that of international terrorism. But Kyoto is quite ineffective, that is, it cannot really affect climate or even change the composition of the atmosphere. It is costly. And it is probably also defunct. Where did this treaty come from? Why is it being adopted by some countries but not by others? And what is its likely future?

The characteristic of the building damage from historical large earthquakes in Kyoto

Science.gov (United States)

Nishiyama, Akihito

2016-04-01

The Kyoto city, which is located in the northern part of Kyoto basin in Japan, has a long history of >1,200 years since the city was initially constructed. The city has been a populated area with many buildings and the center of the politics, economy and culture in Japan for nearly 1,000 years. Some of these buildings are now subscribed as the world's cultural heritage. The Kyoto city has experienced six damaging large earthquakes during the historical period: i.e., in 976, 1185, 1449, 1596, 1662, and 1830. Among these, the last three earthquakes which caused severe damage in Kyoto occurred during the period in which the urban area had expanded. These earthquakes are considered to be inland earthquakes which occurred around the Kyoto basin. The damage distribution in Kyoto from historical large earthquakes is strongly controlled by ground condition and earthquakes resistance of buildings rather than distance from estimated source fault. Therefore, it is necessary to consider not only the strength of ground shaking but also the condition of building such as elapsed years since the construction or last repair in order to more accurately and reliably estimate seismic intensity distribution from historical earthquakes in Kyoto. The obtained seismic intensity map would be helpful for reducing and mitigating disaster from future large earthquakes.

Information System through ANIS at CeSAM

Moreau, C.; Agneray, F.; Gimenez, S.

2015-09-01

ANIS (AstroNomical Information System) is a web generic tool developed at CeSAM to facilitate and standardize the implementation of astronomical data of various kinds through private and/or public dedicated Information Systems. The architecture of ANIS is composed of a database server which contains the project data, a web user interface template which provides high level services (search, extract and display imaging and spectroscopic data using a combination of criteria, an object list, a sql query module or a cone search interfaces), a framework composed of several packages, and a metadata database managed by a web administration entity. The process to implement a new ANIS instance at CeSAM is easy and fast : the scientific project has to submit data or a data secure access, the CeSAM team installs the new instance (web interface template and the metadata database), and the project administrator can configure the instance with the web ANIS-administration entity. Currently, the CeSAM offers through ANIS a web access to VO compliant Information Systems for different projects (HeDaM, HST-COSMOS, CFHTLS-ZPhots, ExoDAT,...).

Domo arigato Kyoto: Four key lessons from the Kyoto Protocol for a new agreement in Paris 2015. Climate Brief no. 35

International Nuclear Information System (INIS)

Morel, Romain; Shishlov, Igor; Bellassen, Valentin

2014-05-01

The results from the first commitment period of the Kyoto Protocol (KP) show that developed countries fulfilled their commitments through varied strategies. However, the Kyoto protocol did not manage to stabilize global GHG concentrations; furthermore its direct impact on domestic emissions reductions is unclear. Nevertheless, the KP has likely paved the way for a low-carbon transition by establishing international standards on emissions monitoring and on emission reductions projects. Yet, domestic policies - especially the EU ETS - are the main driver of emissions reductions and the principal catalyzers of private finance flows. A new, more effective, agreement would therefore need to expand its coverage, and take down the specter of 'internationally binding' emission reductions commitments in order to focus on MRV requirements. Similar to Kyoto, a Paris outcome could take the form of a framework agreement setting up requirements and mechanisms with subsequent implementing agreements expected by 2020. (authors)

Estimates of the costs of Kyoto: Marrakesh versus the McKibbin-Wilcoxen blueprint

International Nuclear Information System (INIS)

McKibbin, Warwick J.; Wilcoxen, Peter J.

2004-01-01

In this paper, we update our earlier estimates of the cost of the Kyoto Protocol using the G-Cubed model, taking into account the new sink allowances from recent negotiations as well as allowing for multiple gases and new land clearing estimates. We then compare the protocol to an alternative policy outlined in McKibbin et al. (Brookings Policy Brief, No. 17. June, The Brookings Institution, Washington, 1997; Climate Change Policy After Kyoto: A Blueprint for a Realistic Approach, The Brookings Institution, Washington, 2002a; J. Econom. Perspect. 16(2) (2002b) 107) that does not impose rigid emissions targets. We focus particular attention on the sensitivity of compliance costs under each policy to unexpected changes in future economic conditions. To illustrate the issue, we evaluate the policies under two plausible alternative assumptions about a single aspect of the future world economy: the rate of productivity growth in Russia. We find that moderate growth in Russia would raise the cost of the Kyoto Protocol by as much as 50 percent but would have little effect on the cost of the alternative policy. We conclude that the Kyoto Protocol is inherently unstable because unexpected future events could raise compliance costs substantially and place enormous pressure on governments to abrogate the agreement. The alternative policy would be far more stable because it does not subject future governments to adverse shocks in compliance costs

The Project Based Mechanisms of the Kyoto Protocol. Credible Instruments or Challenges to the Integrity of the Kyoto Protocol?

Energy Technology Data Exchange (ETDEWEB)

Takeuchi Waldegren, Linn

2006-03-15

The project based mechanisms of the Kyoto Protocol are innovative instruments which allow projects to earn credits for reducing greenhouse gas (GHG) emissions. The credits can in turn be used by countries to reach their emissions targets according to the Kyoto Protocol. The Project based mechanisms are known as the Clean Development Mechanism (CDM) and the Joint Implementation (JI). If the project based mechanisms are to be effective policy instruments they must ensure the integrity of the Kyoto Protocol, and their ability to promote and prove real emission reductions is critical. The environmental credibility of the project based mechanisms will also ensure their ability to promote cost effectiveness. Key concepts in this context are environmental and project additionality, and their role and value for the project based mechanisms are analyzed. Environmental additionality is established by comparing a project's emissions to a baseline. The baseline's credibility is thus vital. The concept of project additionality is somewhat controversial, but is nonetheless of equal importance. The case studies of CDM approved methodologies (AMs) and proposed projects suggest that there are credibility issues that need to be addressed if the project based mechanisms are to promote real emissions reductions.

The costs and benefits of early action before Kyoto compliance

International Nuclear Information System (INIS)

Pan, Haoran; Regemorter, D. van

2004-01-01

Transaction costs have negative effects on emissions trading. Recent debates on the Kyoto Protocol have emphasized the potential threat of transaction costs to the implementation of emissions trading for the Protocol and consequently to the successful implementation of the Protocol. One way to suppress transaction costs is to use experience. In line with the EU Green Paper, we propose that an experimental early action before the Kyoto period could be helpful to reduce the transaction costs in emissions trading for the Kyoto compliance. However, because early action will incur additional costs, the final gain due to early action will be the cost-saving net of the costs of early action. This paper explores the relationship between the transaction costs in emissions trading and the early action effort to reduce transaction costs in the case of Kyoto Protocol. We find that in general early action can effectively offset transaction costs and thus are economically efficient. Only in the case of high transaction costs and constantly slow learning process, early action may become inefficient

Making it work: Kyoto, trade and politics : Executive summary

Urquhar, I.

2002-11-01

In this document, the author examines the constraints that would be placed on policy makers in the event of the implementation of the Kyoto Protocol, and how it would affect trade agreements and federalism in Canada. A description of the Protocol and the concessions (carbon sinks and international emissions trading) gained by Canada are presented at the beginning of the document. The author offers several conclusions that could disturb both proponents and opponents of the Kyoto Protocol. It is said that the implementation of Kyoto can take a route other than that of drastic domestic emissions reductions, and this position is explored in the second section. The author indicates that corporate competitiveness could be boosted by strict environmental regulations. A range of policies that could be adopted by Canada, as proposed by numerous organizations, are highlighted in the third section of the document. The point of the World Trade Organization and the constraints imposed are not necessarily preventing all types of actions. However, the author is of the opinion that the North America Free Trade Agreement represents a real threat to the implementation of the Kyoto Protocol. Finally, it is indicated that Canada requires a national electricity policy, where big hydro utilities and public investment have major roles to play.

Carbon tax effects on the poor: a SAM-based approach

Science.gov (United States)

Chapa, Joana; Ortega, Araceli

2017-09-01

A SAM-based price model for Mexico is developed in order to assess the effects of the carbon tax, which was part of the fiscal reform approved in 2014. The model is formulated based on a social accounting matrix (SAM) that distinguishes households by the official poverty condition and geographical area. The main results are that the sector that includes coke, refined petroleum and nuclear fuel shows the highest price increase due to the direct impact of the carbon tax; in addition, air transport and inland transport are the most affected sectors, in an indirect manner, because both employ inputs from the former sector. Also, it is found that welfare diminishes more in the rural strata than in the urban one. In the urban area, the carbon tax is regressive: the negative impact of carbon tax on family welfare is greater on the poorest families.

The Kyoto Protocol Is Cost-effective

Marino Gatto

2002-06-01

Full Text Available Despite recent advances, there is a high degree of uncertainty concerning the climate change that would result from increasing atmospheric greenhouse gas concentrations. Also, opponents of the Kyoto Protocol raised the key objection that reducing emissions would impose an unacceptable economic burden on businesses and consumers. Based on an analysis of alternative scenarios for electricity generation in Italy, we show that if the costs in terms of damage to human health, material goods, agriculture, and the environment caused by greenhouse gas emissions are included in the balance, the economic argument against Kyoto is untenable. Most importantly, the argument holds true even if we exclude global external costs (those due to global warming, and account for local external costs only (such as those due to acidic precipitation and lung diseases resulting from air pollution.

Vibrational Stark Effect of the Electric-Field Reporter 4-Mercaptobenzonitrile as a Tool for Investigating Electrostatics at Electrode/SAM/Solution Interfaces

Directory of Open Access Journals (Sweden)

Peter Hildebrandt

2012-06-01

Full Text Available 4-mercaptobenzonitrile (MBN in self-assembled monolayers (SAMs on Au and Ag electrodes was studied by surface enhanced infrared absorption and Raman spectroscopy, to correlate the nitrile stretching frequency with the local electric field exploiting the vibrational Stark effect (VSE. Using MBN SAMs in different metal/SAM interfaces, we sorted out the main factors controlling the nitrile stretching frequency, which comprise, in addition to external electric fields, the metal-MBN bond, the surface potential, and hydrogen bond interactions. On the basis of the linear relationships between the nitrile stretching and the electrode potential, an electrostatic description of the interfacial potential distribution is presented that allows for determining the electric field strengths on the SAM surface, as well as the effective potential of zero-charge of the SAM-coated metal. Comparing this latter quantity with calculated values derived from literature data, we note a very good agreement for Au/MBN but distinct deviations for Ag/MBN which may reflect either the approximations and simplifications of the model or the uncertainty in reported structural parameters for Ag/MBN. The present electrostatic model consistently explains the electric field strengths for MBN SAMs on Ag and Au as well as for thiophenol and mercaptohexanoic acid SAMs with MBN incorporated as a VSE reporter.

Industrial output restriction and the Kyoto protocol. An input-output approach with application to Canada

International Nuclear Information System (INIS)

Lixon, Benoit; Thomassin, Paul J.; Hamaide, Bertrand

2008-01-01

The objective of this paper is to assess the economic impacts of reducing greenhouse gas emissions by decreasing industrial output in Canada to a level that will meet the target set out in the Kyoto Protocol. The study uses an ecological-economic Input-Output model combining economic components valued in monetary terms with ecologic components - GHG emissions - expressed in physical terms. Economic and greenhouse gas emissions data for Canada are computed in the same sectoral disaggregation. Three policy scenarios are considered: the first one uses the direct emission coefficients to allocate the reduction in industrial output, while the other two use the direct plus indirect emission coefficients. In the first two scenarios, the reduction in industrial sector output is allocated uniformly across sectors while it is allocated to the 12 largest emitting industries in the last one. The estimated impacts indicate that the results vary with the different allocation methods. The third policy scenario, allocation to the 12 largest emitting sectors, is the most cost effective of the three as the impacts of the Kyoto Protocol reduces Gross Domestic Product by 3.1% compared to 24% and 8.1% in the first two scenarios. Computed economic costs should be considered as upper-bounds because the model assumes immediate adjustment to the Kyoto Protocol and because flexibility mechanisms are not incorporated. The resulting upper-bound impact of the third scenario may seem to contradict those who claim that the Kyoto Protocol would place an unbearable burden on the Canadian economy. (author)

Cooperation between Magnesium and Metabolite Controls Collapse of the SAM-I Riboswitch.

Science.gov (United States)

Roy, Susmita; Onuchic, José N; Sanbonmatsu, Karissa Y

2017-07-25

The S-adenosylmethionine (SAM)-I riboswitch is a noncoding RNA that regulates the transcription termination process in response to metabolite (SAM) binding. The aptamer portion of the riboswitch may adopt an open or closed state depending on the presence of metabolite. Although the transition between the open and closed states is critical for the switching process, its atomistic details are not well understood. Using atomistic simulations, we calculate the effect of SAM and magnesium ions on the folding free energy landscape of the SAM-I riboswitch. These molecular simulation results are consistent with our previous wetlab experiments and aid in interpreting the SHAPE probing measurements. Here, molecular dynamics simulations explicitly identify target RNA motifs sensitive to magnesium ions and SAM. In the simulations, we observe that, whereas the metabolite mostly stabilizes the P1 and P3 helices, magnesium serves an important role in stabilizing a pseudoknot interaction between the P2 and P4 helices, even at high metabolite concentrations. The pseudoknot stabilization by magnesium, in combination with P1 stabilization by SAM, explains the requirement of both SAM and magnesium to form the fully collapsed metabolite-bound closed state of the SAM-I riboswitch. In the absence of SAM, frequent open-to-closed conformational transitions of the pseudoknot occur, akin to breathing. These pseudoknot fluctuations disrupt the binding site by facilitating fluctuations in the 5'-end of helix P1. Magnesium biases the landscape toward a collapsed state (preorganization) by coordinating pseudoknot and 5'-P1 fluctuations. The cooperation between SAM and magnesium in stabilizing important tertiary interactions elucidates their functional significance in transcription regulation. Published by Elsevier Inc.

Submission to the British Columbia government on the Kyoto Protocol

2002-09-01

The Business Council provided its comments concerning the Kyoto Protocol and climate change to the government of British Columbia, recommending that a clear position be established quickly on the matter. The adopted position should also be disseminated broadly to allow stake holders sufficient time to prepare for the upcoming meetings of the Joint Ministers and First Ministers. The federal government has announced that the decision on whether to ratify the Kyoto Protocol will be made before the end of 2002, and this decision will have numerous effects on the people of British Columbia, businesses, workers, and consumers alike. The Business Council of British Columbia believes that the unique interests of the province can best be protected by a proactive approach. Actions plans are being prepared by several of the other provinces and territories, who have already stated their position concerning the Kyoto Protocol. The long-term risks of climate change for British Columbia have not been determined nor have the elements of a provincial approach. The following elements should be included in British Columbia's position on the Kyoto Protocol, according to the Business Council of British Columbia: (1) a credible and cost-effective implementation plan that does not unduly burden the province and other jurisdictions must be developed before Canada decides to ratify the Protocol. British Columbia should go on the record stating it does not support the ratification of the Kyoto Protocol in its present form. (2) the province should advocate for a national approach to climate change that can be achieved within a reasonable time frame, reflects the long-term nature of the problem, and is in agreement with the economic development objectives of British Columbia, (3) a plan detailing how the province intends to deal with the growth of greenhouse gas emissions should supplement and support the position of the province on the Kyoto Protocol. Consumers and business should be engaged

Kyoto protocol and Nepal's energy sector

International Nuclear Information System (INIS)

Pokharel, Shaligram

2007-01-01

Nepal has recently ratified Kyoto Protocol, which considers justifiable use of resources to limit or reduce the emission of gases that contribute to green house gas inventory in the atmosphere. Nepal's per capita green gas (GHG) emission from energy use is insignificant. However, it is important for Nepal to adopt environmentally friendly energy options based on local resources like hydropower and biomass. Nepal can benefit from the provisions of clean development mechanism (CDM) under the Kyoto Protocol of the United Nations Framework Convention on Climate Change (UNFCC) or carbon funds being promoted by various organizations in order to obtain funding for new projects that reduce GHG emissions (ER). Funding can be generated through Carbon trading in international market as well. In this paper, the country's current contribution to GHG due to energy consumption is evaluated. Options for promoting more sustainable and environmentally friendly projects have also been discussed

Influence of outdoor advertisement colors on psychological evaluation of townscape in Kyoto

Onishi, Ayumi; Ishida, Taiichiro; Katsuya, Yoshiko

2002-06-01

Outdoor advertisements must be one of the major factors that affect our psychological impression for townscapes. They often conflict with propr color environments in cities particularly in historic cities like Kyoto. In this study we investigated how outdoor advertisements influenced our visual evaluation of townscapes in Kyoto. In recent years, a new regulation for outdoor advertisements came into operation in Kyoto and some of the advertisements have been replaced or removed gradually. We examined psychological evaluation for the townscapes before and after their changes. In the experiment, subjects evaluated 'visual harmony,' 'visual busyness,' 'visual comfort' and 'suitability to Kyoto' of townscapes projected on a screen. The results indicated that the evaluation of 'visual busyness' significantly decreased with the amount of the advertisements. The relations between the advertisements and the psychological evaluation of the townscape are discussed.

The Kyoto mechanisms and the diffusion of renewable energy technologies in the BRICS

Bodas Freitas, Isabel Maria; Dantas, Eva; Iizuka, Michiko

2012-01-01

This paper examines whether the Kyoto mechanisms have stimulated the diffusion of renewable energy technologies in the BRICS, i.e. Brazil, Russian, India China and South Africa. We examine the patterns of diffusion of renewable energy technologies in the BRICS, the factors associated with their diffusion, and the incentives provided by the Kyoto mechanisms. Preliminary analysis suggests that the Kyoto mechanisms may be supporting the spread of existing technologies, regardless if such technologies are still closely tied to environmental un-sustainability, rather than the development and diffusion of more sustainable variants of renewable energy technologies. This raises questions about the incentives provided by the Kyoto mechanisms for the diffusion of cleaner variants of renewable energy technologies in the absence of indigenous technological efforts and capabilities in sustainable variants, and national policy initiatives to attract and build on Kyoto mechanism projects. We provide an empirical analysis using aggregated national data from the World Development Indicators, the International Energy Agency, the United Nations Framework Convention on Climate Change and secondary sources. - Highlights: ► The Kyoto mechanisms may be supporting the diffusion of existing technologies. ► They may not be supporting the diffusion of sustainable renewable energy technologies. ► In the absence of appropriate capabilities and policies further diffusion is limited.

The ALICE Glance Shift Accounting Management System (SAMS)

Science.gov (United States)

Martins Silva, H.; Abreu Da Silva, I.; Ronchetti, F.; Telesca, A.; Maidantchik, C.

2015-12-01

ALICE (A Large Ion Collider Experiment) is an experiment at the CERN LHC (Large Hadron Collider) studying the physics of strongly interacting matter and the quark-gluon plasma. The experiment operation requires a 24 hours a day and 7 days a week shift crew at the experimental site, composed by the ALICE collaboration members. Shift duties are calculated for each institute according to their correlated members. In order to ensure the full coverage of the experiment operation as well as its good quality, the ALICE Shift Accounting Management System (SAMS) is used to manage the shift bookings as well as the needed training. ALICE SAMS is the result of a joint effort between the Federal University of Rio de Janeiro (UFRJ) and the ALICE Collaboration. The Glance technology, developed by the UFRJ and the ATLAS experiment, sits at the basis of the system as an intermediate layer isolating the particularities of the databases. In this paper, we describe the ALICE SAMS development process and functionalities. The database has been modelled according to the collaboration needs and is fully integrated with the ALICE Collaboration repository to access members information and respectively roles and activities. Run, period and training coordinators can manage their subsystem operation and ensure an efficient personnel management. Members of the ALICE collaboration can book shifts and on-call according to pre-defined rights. ALICE SAMS features a user profile containing all the statistics and user contact information as well as the Institutes profile. Both the user and institute profiles are public (within the scope of the collaboration) and show the credit balance in real time. A shift calendar allows the Run Coordinator to plan data taking periods in terms of which subsystems shifts are enabled or disabled and on-call responsible people and slots. An overview display presents the shift crew present in the control room and allows the Run Coordination team to confirm the presence

Background of SAM atom-fraction profiles

Ernst, Frank

2017-01-01

Atom-fraction profiles acquired by SAM (scanning Auger microprobe) have important applications, e.g. in the context of alloy surface engineering by infusion of carbon or nitrogen through the alloy surface. However, such profiles often exhibit an artifact in form of a background with a level that anti-correlates with the local atom fraction. This article presents a theory explaining this phenomenon as a consequence of the way in which random noise in the spectrum propagates into the discretized differentiated spectrum that is used for quantification. The resulting model of “energy channel statistics” leads to a useful semi-quantitative background reduction procedure, which is validated by applying it to simulated data. Subsequently, the procedure is applied to an example of experimental SAM data. The analysis leads to conclusions regarding optimum experimental acquisition conditions. The proposed method of background reduction is based on general principles and should be useful for a broad variety of applications. - Highlights: • Atom-fraction–depth profiles of carbon measured by scanning Auger microprobe • Strong background, varies with local carbon concentration. • Needs correction e.g. for quantitative comparison with simulations • Quantitative theory explains background. • Provides background removal strategy and practical advice for acquisition

The proposed method of background reduction is based on general principles and should be useful for a broad variety of applications. - Highlights: • Atom-fraction–depth profiles of carbon measured by scanning Auger microprobe • Strong background, varies with local carbon concentration. • Needs correction e.g. for quantitative comparison with simulations • Quantitative theory explains background. • Provides background removal strategy and practical advice for acquisition.

Kyoto Protocol: Debate on environment and development in the discussions on Climate Change

Rodriguez S, Liliana

2007-01-01

The climatic behavior of the planet and its consequences has favored debates about the models of development of the countries responsible for the accelerated deterioration of the atmosphere and of the natural phenomena by these recurrent days. Nevertheless, countries as United States, after signing commitments as the Convention on Climatic Change, refuse to acquire the obligations of the Kyoto Protocol, from fear of undergoing deterioration in their economies. In this setting, where the nation responsible for the emission of approximately 36% of the turned out effect greenhouse gases result of the human action in the planet does not commit itself to adopt restrictive policies to make its models of production but friendly with the nature although these measures begin to be imposed to other nations as determining factors in the international commercial negotiations, seems to be that the adoption of the Kyoto Protocol for developing countries as Colombia is not absolutely beneficial

The Cost of Compliance: A CGE Assessment of Canada's Policy Options under the Kyoto Protocol

Canada is committed under the Kyoto Protocol to reduce greenhouse gas emissions between 2008 and 2012 to a level six percent below the 1990 reference value. To date, however, Canada's greenhouse gas emissions remain far above 1990 levels. Stringent short-term policy measures are needed if Canada is to meet this legally binding commitment. This paper uses a multi-region, multi-commodity static general equilibrium model to quantify the economic impacts of alternative compliance strategies for Canada in the context of climate policies undertaken by other Kyoto Parties. The numerical results confirm fears among Canadian policy makers of larger economic adjustment cost should Canada fulfill its Kyoto commitment solely through domestic action. Comprehensive use of flexible mechanisms - in particular the Clean Development Mechanism - could allow Canada to live up with its international climate policy commitment at a substantially lower economic cost

Will OPEC lose from the Kyoto Protocol?

International Nuclear Information System (INIS)

Barnett, Jon; Dessai, Suraje; Webber, Michael

2004-01-01

A range of energy-economy models forecast losses to members of the Organisation of Petroleum Exporting Countries (OPEC) should the Kyoto Protocol come into force. These forecasts are a powerful influence in the United Nations Framework Convention on Climate Change negotiations. They are used by OPEC to advance the agenda on the impacts of response measures, covertly arguing for compensation for lost oil revenues arising from implementation of the Protocol. This paper discusses this issue, and explores the key assumptions of these models and their uncertainties. Assumptions about carbon leakage, future availability of oil reserves, substitution, innovation, and capital turnover are considered. The paper suggests that losses will not affect OPEC countries equally, and that these losses are not likely to be as substantial as the models forecast. A range of policy measures are proposed to lessen any impact the Protocol may have on OPEC

Emission trading and Kyoto's protocol: discussions concerning rules and international coordination

International Nuclear Information System (INIS)

Baron, R.

2000-01-01

The Kyoto Protocol of the Climate Convention introduced the possibility to trade greenhouse gas emission reductions among industrialized countries, as a means to reduce the total cost of achieving the agreed emission goals. The rules for this international co-ordination regime are still debated, even if its principle is generally agreed. This article, written before the negotiation in the Hague, summarizes how the notion of emission trading made its way in the Framework Convention on Climate Change. The authors show what economic gains could realistically be expected from emission trading, based on macro-economic modelling results and a simulation of trading in the conditions of the Kyoto Protocol. They stress the critical contribution that emission trading could make, provided that the Protocol's environmental basis is not undermined. In the end, the negotiation collapsed over this issue. Beyond this near-term obstacle, the international emission trading system represents a significant progress towards an efficient resolution of man-made global climate change. (author)

Climate change ratification of the Kyoto Protocol : clearing the air on the debate

International Nuclear Information System (INIS)

2002-01-01

The Kyoto Protocol on Climate Change would commit Canada to limit emissions of greenhouse gases to 6 per cent below 1990 levels by 2008-2012. The Canadian Chamber of Commerce has outlined the following 3 key prerequisites that the federal government should and will have in place before any decision on ratification is made: (1) a detailed plan for achieving the Kyoto reductions, (2) a detailed analysis of environmental and economic impacts associated with Kyoto implementation, and (3) consultations with all stakeholder and the Canadian public once the plan has been released. Currently, Canadian businesses are taking voluntary actions to reduce industrial sector emissions through programs such as the Canadian Industry Program for Energy Conservation. Between 1990 and 1999, industrial sector emissions fell by 6 per cent. However, it was emphasized that despite these efforts, the gap between Canada's Kyoto target and its current greenhouse gas emissions continues to grow because of population and economic growth and rising exports. At the current rate of growth, it is estimated that meeting the Kyoto target could cost the economy up to $30 billion in 2010. The paper also discusses the implementation of key flexibility mechanisms such as carbon sinks, Joint Implementation, the Clean Development Mechanism and credits for export of cleaner energy to the United States, a non-Kyoto country. It is argued that ratification of Kyoto could hurt investments and impact jobs in Canada by making Canadian industries uncompetitive relative to their American counterparts. It is emphasized that full participation by the Canadian public is required in adapting to major lifestyle changes to reduce the use of fossil fuels and other sources of greenhouse gases. In conclusion, the Canadian Chamber of Commerce does not believe that the Kyoto Protocol is the most effective and efficient way of moving forward on the climate change issue and recommends that the federal government develop a made

Soil respiration and its role in Russia's terrestrial C flux balance for the Kyoto baseline year

International Nuclear Information System (INIS)

Stolbovoi, Vladimir

2003-01-01

This study introduces a transparent, operational model of estimating soil respiration (SR) to meet the requirements of the Kyoto Protocol of the United Nation Framework Convention on Climate Change within a framework of full carbon accounting (Nilsson et al.; 2000). By applying this model, we are able to define SR for the Kyoto 1990 baseline year for Russia (3200 Tg C), and establish soil emission thresholds for any spatial units, e.g. vegetation zones and land-use patterns. This model is built upon a fundamental biogeochemical cycle and provides a scientific basis for carbon management. SR comprised about 74% of the photosynthetically assimilated carbon in 1990, with the remainder accounted for in several areas. The carbon flux balance is, therefore, found to be closed for Russia. Our findings suggest that incomplete accounting is the reason for missing carbon globally

Sam68 (Src-associated in mitosis of 68 kD), a KH domain RNA-binding protein, is not only important in signaling transduction cascades, but crucial in a variety of cellular processes. Sam68 is reported to be involved in the phospoinositide3-kinase (PI3K) and nuclear factor-kappa B (NF-κB) signaling pathways, and it is closely associated with cell proliferation, RNA metabolism, and tumor progression. However, we know little about the role of Sam68 during peripheral nervous system injury and regeneration. In this study, we investigated the expression of Sam68 and its biological significances in sciatic nerve crush. Interestingly, we found Sam68 had a co-localization with S100 (Schwann cell marker). Moreover, after crush, Sam68 had a spatiotemporal protein expression, which was in parallel with proliferation cell nuclear antigen (PCNA). In vitro, we also observed increased expression of Sam68 during the process of TNF-α-induced Schwann cell proliferation model. Besides, flow cytometry analyses, CCK-8, and EDU were all performed with the purpose of investigating the role of Sam68 in the regulation of Schwann cell proliferation. Even more importantly, we discovered that Sam68 could enhance the phosphorylation of Akt while LY294002 (a PI3K inhibitor) obviously reversed Sam68-induced cell proliferation. Finally, we detected the variance during regeneration progress through the rat walk footprint test. In summary, all these evidences demonstrated that Sam68 might participate in Schwann cell proliferation partially via PI3K/Akt pathway and also regulate regeneration after sciatic nerve crush. -- Highlights: •The dynamic changes and location of Sam68 after sciatic nerve crush. •Sam68 promoted Schwann cell proliferation via PI3K/Akt pathway. •Sam68 modulated functional recovery after sciatic nerve crush.

The role of RNA-binding proteins in the central nervous system and more specifically their role in motor coordination and learning are poorly understood. We previously reported that ablation of RNA-binding protein Sam68 in mice results in male sterility and delayed mammary gland development and protection against osteoporosis in females. Sam68 however is highly expressed in most regions of the brain especially the cerebellum and thus we investigated the cerebellar-related manifestations in Sam68-null mice. We analyzed the mice for motor function, sensory function, and learning and memory abilities. Herein, we report that Sam68-null mice have motor coordination defects as assessed by beam walking and rotorod performance. Forty-week-old Sam68-null mice (n=12) were compared to their wild-type littermates (n=12). The Sam68-null mice exhibited more hindpaw faults in beam walking tests and fell from the rotating drum at lower speeds and prematurely compared to the wild-type controls. The Sam68-null mice were, however, normal for forelimb strength, tail-hang reflex, balance test, grid walking, the Morris water task, recognition memory, visual discrimination, auditory stimulation and conditional taste aversion. Our findings support a role for Sam68 in the central nervous system in the regulation of motor coordination.

Two roads to Kyoto: more or less

Energy Technology Data Exchange (ETDEWEB)

Stanford, J. [Canadian Auto Workers Union (Canada)

2003-01-01

According to this author, in implementing the Kyoto Protocol Canadians are faced with two alternatives: one is consuming less, driving less, and turning down the thermostat, the other is to follow the route of using energy more efficiently, which would allow us to continue to do what we like to do, including driving and staying warm in the winter. The author contends that the federal government's plan relies too heavily on moral suasion, guilt-tripping consumers into reducing their driving and reducing their GHG emissions by turning down their thermostats. The method more likely to succeed would be to encourage fuel-efficient technologies, providing incentives to promote the early commercial production in Canada of low-emission vehicles, along with tax incentives and mandatory market penetration targets. Sensible measures to push automakers to continue improving the average fuel efficiency of new vehicles, shaping and regulating the auto industry to speed up the development of hybrid fuel vehicles and other technological innovations such as continuously variable transmissions, variable valve control and direct injection technologies in engines would also advance the cause of energy efficiency. Regulations regarding motor vehicle recycling, other policies to promote steel recycling, incentives, including higher gasoline taxes, and measures which would mesh with a broader strategy to help Canadians to meet their own Kyoto challenges, are also badly needed. The right decisions on these matters will determine whether ratifying the Kyoto Protocol will be beneficial or detrimental to the Canadian economy.

In the last two decades increasing attention has been paid to the relationship between environmental degradation and economic development. According to the Environmental Kuznets Curve (EKC) hypothesis this relationship may be described by an inverted-U curve. However, recent evidence rejects the EKC hypothesis for GHG emissions in a broad sense. In this paper we aim to investigate whether the EKC behavior for CO2 emissions could be proved on the behalf of institutional regulations. We analyze the driving factors of CO2 for developed and developing countries to test the theory of the EKC in the context of environmental regulations using a static and dynamic panel data model. We consider the Kyoto Protocol and the Clean Development Mechanism (CDM). The results from this study indicate that the Kyoto obligations have a reducing effect on CO2 emissions in developed and developing countries. (orig.)

Understanding bacterial adhesion on a surface is a crucial step to design new materials with improved properties or to control biofilm formation and eradication. Sum Frequency Generation (SFG) vibrational spectroscopy has been employed to study in situ the conformational response of a self-assembled monolayer (SAM) of octadecanethiol (ODT) on a gold film to the adhesion of hydrophilic and hydrophobic ovococcoid model bacteria. The present work highlights vibrational SFG spectroscopy as a powerful and unique non-invasive biophysical technique to probe and control bacteria interaction with ordered surfaces. Indeed, the SFG vibrational spectral changes reveal different ODT SAM conformations in air and upon exposure to aqueous solution or bacterial adhesion. Furthermore, this effect depends on the bacterial cell surface properties. The SFG spectral modeling demonstrates that hydrophobic bacteria flatten the ODT SAM alkyl chain terminal part, whereas the hydrophilic ones raise this ODT SAM terminal part. Microorganism-induced alteration of grafted chains can thus affect the desired interfacial functionality, a result that should be considered for the design of new reactive materials. © 2011 American Chemical Society

GHG emission in the upstream step of fossil fuel chains could give an environmental as well as economic opportunity for traditional sectors. This study deepens the matter showing an increasing number of initiative over the last few years taken both the involved sectors and by various stake holders (public and private subjects) within the Kyoto flexible mechanism (CDM and JI) or linked to voluntary national or at a global level actions. The above undertakings give evidence for an increased interest and an actual activity dealing with GHG reduction whose results play an evident and positive role for the environment too. Part 1. of this study deals with fossil fuel actions within the Kyoto protocol mechanism. Part 2. will show international and national voluntary initiative [it

Exploring the ancillary benefits of the Kyoto Protocol for air pollution in Europe

An integrated approach to climate change and regional air pollution can harvest considerable ancillary benefits in terms of environmental impacts and costs. This is because both problems are caused to a large extent by the same activity (fossil fuel combustion). Substantial ancillary benefits were found for regional air pollution (SO 2 , NO x , VOC and particulate matter) of implementing the Kyoto Protocol (intended to control greenhouse gas emissions) in Europe. For instance, while three different scenarios on Kyoto implementation were found to reduce European CO 2 emissions by 4-7%, they also reduced European emissions of SO 2 by 5-14% compared with a no Kyoto policies case. The magnitude of ancillary benefits depends on how flexible mechanisms and surplus emission allowances are used in meeting the Kyoto targets. The total cost savings for implementing current policies for regional air pollution of the Kyoto Protocol are of an order of 2.5-7 billion Euro. In all cases, this is in the order of half the costs of the climate policy (4-12 billion Euro). Using flexible mechanisms reduces emissions of air pollutants for Europe as a whole even further than domestic implementation (e.g. 10-14% versus 5% for SO 2 emissions), but the reductions are shifted from Western Europe to Central and Eastern Europe and Russia. The use of surplus emission allowances to achieve the Kyoto targets decreases the ancillary benefits, in particular for the latter group of countries (e.g. unprotected area against acidification increases from 1.3 to 1.7 million ha)

Highlights: • Identification of cis elements responsible for SamDC expression by in silico analysis. • qPCR analysis of SamDC expression to abiotic and biotic stress treatments. • Detection of SamDC regulators using identified cis-elements as probe by EMSA. • Southwestern Blot analysis to predict the size of the trans-acting factors. - Abstract: Abiotic stress affects the growth and productivity of crop plants; to cope with the adverse environmental conditions, plants have developed efficient defense machinery comprising of antioxidants like phenolics and flavonoids, and osmolytes like polyamines. SamDC is a key enzyme in the polyamine biosynthesis pathway in plants. In our present communication we have done in silico analysis of the promoter region of SamDC to look for the presence of different cis-regulatory elements contributing to its expression. Based on the presence of different cis-regulatory elements we completed comparative analysis of SamDC gene expression in rice lamina of IR-29 and Nonabokra by qPCR in response to the abiotic stress treatments of salinity, drought, cold and the biotic stress treatments of ABA and light. Additionally, to explore the role of the cis-regulatory elements in regulating the expression of SamDC gene in plants we comparatively analyzed the binding of rice nuclear proteins prepared from IR-29 and Nonabokra undergoing various stress treatments. The intensity of the complex formed was low and inducible in IR-29 in contrast to Nonabokra. Southwestern blot analysis helped in predicting the size of the trans-acting factors binding to these cis-elements. To our knowledge this is the first report on the comprehensive analysis of SamDC gene expression in rice and identification of the trans-acting factors regulating its expression.

Radical SAM enzymes generally contain a [4Fe-4S](2+/1+) (RS cluster) cluster bound to the protein via the three cysteines of a canonical motif CxxxCxxC. The non-cysteinyl iron is used to coordinate SAM via its amino-carboxylate moiety. The coordination-induced proximity between the cluster acting as an electron donor and the adenosyl-sulfonium bond of SAM allows for the homolytic cleavage of the latter leading to the formation of the reactive 5'-deoxyadenosyl radical used for substrate activation. Most of the structures of Radical SAM enzymes have been obtained in the presence of SAM, and therefore, little is known about the situation when SAM is not present. In this report, we show that RimO, a methylthiotransferase belonging to the radical SAM superfamily, binds a Tris molecule in the absence of SAM leading to specific spectroscopic signatures both in Mössbauer and pulsed EPR spectroscopies. These data provide a cautionary note for researchers who work with coordinative unsaturated iron sulfur clusters.

The study of age-related changes in the central nervous system due to irradiation is being carried out in our laboratory. The senescence accelerated mouse (SAM P/1, male) was used for this investigation concerning the one-trial passive avoidance reaction. The experimental group of SAM P/1 was irradiated with 4 Gy at 8 weeks old, and passive avoidance reaction (PAR) was measured for 180 seconds as a learning task. At the age of 7 months, statistical analysis of PAR was conducted using the life time analysis method. The passive avoidance reaction of the irradiated group was more impaired than that of the control group. The results of this investigation suggested that the learning and/or memory disturbance of irradiated SAM P/1 is similar to the changes of more aged SAM P/1. (author)

Climate policy after Kyoto

International Nuclear Information System (INIS)

Gerholm, T.R.

2002-01-01

The Kyoto Convention recommends reductions in emissions of CO 2 and other greenhouse gases, to mitigate the rate of climate change. Lively debate has taken place in many countries, not least over the political and economic implications. The basis for the Kyoto discussions was a set of studies commissioned, compiled and published by the UN's International Panel on Climate Change (IPCC). At first glance this scientific foundation plainly shows that significant climate change will occur unless emissions of greenhouse gases are sharply curtailed. On closer examination, the scientific evidence provided in the IPCC material is far from clear. Reputable scientists have expressed critical views about the interpretation of the scientific results and, even more, of the way the material is being used for policy purposes. The main purpose of this book is to voice this critique. To give the reader some context, a central section from the IPCC's basic document is presented first. There follow nine papers, by prominent natural and social scientists, in which the reasons for their sceptical attitudes are developed. A final paper by Professor Bert Bolin, chairman of the IPCC during the time when most of the material was produced, provides a response and commentary to the critique. The aim of the editor and authors, in presenting the material in this way, rather than as a polemical tract, is to leave open to the reader the question: Is global warming a consequence of man's activities, or are there other reasons; if so, is adopting policies with significant economic consequences, a reasonable response?

Buonanno, Paolo; Carraro, Carlo; Galeotti, Marzio

2003-01-01

We present a model for climate change policy analysis which accounts for the possibility that technology evolves endogenously and that technical change can be induced by environmental policy measures. Both the output production technology and the emission-output ratio depend upon a stock of knowledge, which accumulates through R and D activities. Two versions of this model are studied, one with endogenous technical change but exogenous environmental technical change and the other with both endogenous and induced technical change. A third version also captures technological spillover effects. As an application, the model is simulated allowing for trade of pollution permits as specified in the Kyoto Protocol and assessing the implications in terms of cost efficiency, economic growth and R and D efforts of the three different specifications of technical change

2005-01-01

The Kyoto Protocol to the United Nations Framework Convention on Climate Change aims to reduce greenhouse gas emissions by urging the international community to take measures preventing 'dangerous man-made interference with the climate system'. Since its publication in 1997, the Kyoto Protocol has triggered heated debates among scientists and politicians. According to a number of critics, the questions as to whether global warming is caused by human intervention, and whether taking appropriate measures could reduce the trend, has not yet been conclusively answered. In a limited number of countries, this situation has led to a delay in the ratification process. Only when these disputes were settled in February 2005 the Kyoto Protocol became legally binding on all the signatories. If predictions are accurate, measures have to be taken to prevent a global catastrophe. This leads to another, much overlooked, but no less important question, namely how mankind can be motivated to accept the burden attached to the measures proposed by the Kyoto Protocol; in other words, how do we find and formulate an ethical basis for measures forcing us to sacrifice some of our wealth and riches, for a cleaner, more sustainable world?

A polarized ion source developed under the National Laboratory of High Energy Physics was transferred to the tandem accelerator in Kyoto University at beginning of 1993 to constitute a displacement of incidence into the accelerator. This was an atomic beam type polarized ion source, which is designed to adopt permanent magnets for 6 poles magnet to polarize the electron, to take out atomic nucleus on a shape of positive ion by ECR ionizer after transferring its polarization through transition using radio frequency (RFT), to make it negative ion by charge conversion using alkaline metal vapor, and to put it into the tandem accelerator. Test of the positive ion was finished at the National Laboratory of High Energy Physics, and test in Kyoto University was required after its negative ionization. As the estimated cost was unsufficient and entrance into the ion source facility in the tandem accelerator building was limited in Kyoto University, step of development was slow. Here is reported on present state of the ion source which is now operating stably. (G.K.)

Kyoto Protocol Objectives in Croatia Energy Planning: Nuclear Scenario

Croatia as an Annex I country of the United Nations Framework Convention on Climate Change (UNFCCC) and a country that has pledged in the Annex B of the Kyoto Protocol to reduce its greenhouse gases (GHG) emissions by 5% from the pre-transition level by the budget period 2008-12, will have to envisage a new energy strategy. Compared to the energy consumption collapse in some transitional countries like Russia and Ukraine, Croatia has passed through a relatively limited long term reduction of GHG emissions since 1990 because of higher efficiency of its pre-transition economy. It is expected that in case of business as usual scenario it will breach the Kyoto target in 2003 since the demand for energy will be high, especially as the income continues to rise, particularly in domestic use for heating, for transport and for electricity generation. Several scenarios of developing energy system are compared from the point of view of GHG emissions. The energy sector that will most probably be the most influenced by the UNFCCC objectives is electricity generation. Several scenarios are compared. The cost-effective scenario expects a mixture of coal and gas fired power plants to be built to satisfy the new demand and to replace the old power plants that are being decommissioned. More Kyoto friendly scenario envisages the construction of mostly nuclear power plants in the future, while decommissioning the old ones as planned, and is compared to the others from the GHG emissions point of view. The conclusion is that by measures tackling only electricity generation it will not be possible to keep GHG emission under the Kyoto target level, but that choosing the nuclear option might reduce significantly the cost of compliance.

The Kyoto Protocol to the United Nations Framework Convention on Climate Change contains quantified, legally binding commitments to limit or reduce greenhouse gas emissions to 1990 levels and allows carbon emissions to be balanced by carbon sinks represented by vegetation. The issue of using vegetation cover as an emission offset raises a debate about the adequacy of current remote sensing systems and data archives to both assess carbon stocks/sinks at 1990 levels, and monitor the current and future global status of those stocks. These concerns and the potential ratification of the Protocol among participating countries is stimulating policy debates and underscoring a need for the exchange of information between the international legal community and the remote sensing community. On October 20-22 1999, two working groups of the International Society for Photogrammetry and Remote Sensing (ISPRS) joined with the University of Michigan (Michigan, USA) to convene discussions on how remote sensing technology could contribute to the information requirements raised by implementation of, and compliance with, the Kyoto Protocol. The meeting originated as a joint effort between the Global Monitoring Working Group and the Radar Applications Working Group in Commission VII of the ISPRS, co-sponsored by the University of Michigan. Tile meeting was attended by representatives from national government agencies and international organizations and academic institutions. Some of the key themes addressed were: (1) legal aspects of transnational remote sensing in the context of the Kyoto Protocol; (2) a review of the current and future and remote sensing technologies that could be applied to the Kyoto Protocol; (3) identification of areas where additional research is needed in order to advance and align remote sensing technology with the requirements and expectations of the Protocol; and 94) the bureaucratic and research management approaches needed to align the remote sensing

While the popularity of smartphones has given enormous convenience to our lives, their pathological use has created a new mental health concern among the community. Hence, intensive research is being conducted on the etiology and treatment of the condition. However, the traditional clinical approach based surveys and interviews has serious limitations: health professionals cannot perform continual assessment and intervention for the affected group and the subjectivity of assessment is questionable. To cope with these limitations, a comprehensive ICT (Information and Communications Technology) system called SAMS (Smartphone Addiction Management System) is developed for objective assessment and intervention. The SAMS system consists of an Android smartphone application and a web application server. The SAMS client monitors the user's application usage together with GPS location and Internet access location, and transmits the data to the SAMS server. The SAMS server stores the usage data and performs key statistical data analysis and usage intervention according to the clinicians' decision. To verify the reliability and efficacy of the developed system, a comparison study with survey-based screening with the K-SAS (Korean Smartphone Addiction Scale) as well as self-field trials is performed. The comparison study is done using usage data from 14 users who are 19 to 50 year old adults that left at least 1 week usage logs and completed the survey questionnaires. The field trial fully verified the accuracy of the time, location, and Internet access information in the usage measurement and the reliability of the system operation over more than 2 weeks. The comparison study showed that daily use count has a strong correlation with K-SAS scores, whereas daily use times do not strongly correlate for potentially addicted users. The correlation coefficients of count and times with total K-SAS score are CC = 0.62 and CC =0.07, respectively, and the t-test analysis for the

Emission Trading and the Kyoto protocol: Are they efficient economic instruments?

International Nuclear Information System (INIS)

Ibanez Londono, Ana Maria

1998-02-01

The Kyoto Protocol establishes a tradeable permits market for green house gases -GHG- emissions to reduce the costs of meeting the Protocol obligations. Economic theory provides the arguments to support the creation of GHG tradeable permits. Several economic researches have shown that vis-a-vis command and control regulations, tradeable permits induce economic agents to achieve environmental goals at a minimum cost. However, the conditions to minimize costs through tradeable permits are stringent. Tradeable permits require well functioning markets, e.g. perfect competition and perfect information. The tradeable permits market created by the Kyoto Protocol hardly meet these necessary conditions. Some countries like Japan, Great Britain and the United Stated are large emitters and thus may exert market power. Price manipulation may have implications over the static and dynamic efficiency of the permits. This paper takes a first look to the consequences of imperfect markets on the tradeable permit system of the Kyoto Protocol

For each NPP, severe accident management (SAM) strategies shall make use of components or systems and human resources to limit as far as possible the consequences of any severe accident on-site and off-site. L2 PSA is one of the tools that can be used to verify and improve these strategies. The present report (deliverable D40.5 of the project ASAMPSA-E) provides an opportunity for a comparison of objectives in the different countries in terms of SAM strategies verification and improvement. The report summarizes also experience of each partner (including potential deficiencies) involved in this activity, in order to derive some good practices and required progress, addressing: - SAM modeling in L2 PSA, - Positive and negative aspects in current SAM practices, - Discussion on possible criteria related to L2 PSA for verification and improvement: risk reduction (in relation with WP30 activities on risk metrics), reduction of uncertainties on the severe accident progression paths until NPP stabilization, reduction of human failure conditional probabilities (depending on the SAM strategy, the environmental conditions...), - Review with a perspective of verification and improvement of the main SAM strategies (corium cooling, RCS depressurization, control of flammable gases, reactivity control, containment function, containment pressure control, limitation of radioactive releases,...), - SAM strategies to be considered in the context of an extended L2 PSA (as far possible, depending on existing experience), taking into account all operating modes, accidents also occurring in the SFPs and long term and multi-unit accidents. The deliverable D40.5 is developed from the partners' experience. Many of the topics described here are beyond the common practices of L2 PSA applications: in some countries, L2 PSA application is limited to the calculations of frequencies of release categories with no formal requirement for SAM verification and improvement.

Introduction: An important goal of upcoming missions to Mars is to understand if life could have developed there. The task of the Sample Analysis at Mars (SAM) suite of instruments [1] and the other Curiosity investigations [2] is to move us steadily toward that goal with an assessment of the habitability of our neighboring planet through a series of chemical and geological measurements. SAM is designed to search for organic compounds and inorganic volatiles and measure isotope ratios. Other instruments on Curiosity will provide elemental analysis and identify minerals. SAM will analyze both atmospheric samples and gases evolved from powdered rocks that may have formed billions of years ago with Curiosity providing access to interesting sites scouted by orbiting cameras and spectrometers. SAM Instrument Suite: SAM’s instruments are a Quadrupole Mass Spectrometer (QMS), a 6-column Gas Chromatograph (GC), and a 2-channel Tunable Laser Spectrometer (TLS). SAM can identify organic compounds in Mars rocks to sub-ppb sensitivity and secure precise isotope ratios for C, H, and O in carbon dioxide and water and measure trace levels of methane and its carbon 13 isotope. The SAM gas processing system consists of valves, heaters, pressure sensors, gas scrubbers and getters, traps, and gas tanks used for calibration or combustion experiments [2]. A variety of calibrant compounds interior and exterior to SAM will allow the science and engineering teams to assess SAM’s performance. SAM has been calibrated and tested in a Mars-like environment. Keeping Educators and the Public Informed: The Education and Public Outreach (EPO) goals of the SAM team are to make this complex chemical laboratory and its data widely available to educators, students, and the public. Formal education activities include developing templates for professional development workshops for educators to teach them about SAM and Curiosity, incorporating data into Mars Student Data Teams, and writing articles

Alternative function for the mitochondrial SAM complex in biogenesis of alpha-helical TOM proteins.

Science.gov (United States)

Stojanovski, Diana; Guiard, Bernard; Kozjak-Pavlovic, Vera; Pfanner, Nikolaus; Meisinger, Chris

2007-12-03

The mitochondrial outer membrane contains two preprotein translocases: the general translocase of outer membrane (TOM) and the beta-barrel-specific sorting and assembly machinery (SAM). TOM functions as the central entry gate for nuclear-encoded proteins. The channel-forming Tom40 is a beta-barrel protein, whereas all Tom receptors and small Tom proteins are membrane anchored by a transmembrane alpha-helical segment in their N- or C-terminal portion. Synthesis of Tom precursors takes place in the cytosol, and their import occurs via preexisting TOM complexes. The precursor of Tom40 is then transferred to SAM for membrane insertion and assembly. Unexpectedly, we find that the biogenesis of alpha-helical Tom proteins with a membrane anchor in the C-terminal portion is SAM dependent. Each SAM protein is necessary for efficient membrane integration of the receptor Tom22, whereas assembly of the small Tom proteins depends on Sam37. Thus, the substrate specificity of SAM is not restricted to beta-barrel proteins but also includes the majority of alpha-helical Tom proteins.

Ten years have passed since December 1997, when the United Nations Framework Convention on Climate Change (UNFCCC) was signed in Kyoto. It's been a decade of tough international negotiations, leading to the beginnings of an international CO{sub 2} emissions trading market, whose future past 2012 remains uncertain. The December negotiations in Bali may not have produced a successor to the Kyoto Protocol, but they did get all parties to the Convention to sign an agreement in principle to post- Kyoto negotiations.

As if Kyoto mattered: The clean development mechanism and transportation

International Nuclear Information System (INIS)

Christopher Zegras, P.

2007-01-01

Transportation is a major source of greenhouse gas (GHG) emissions and the most rapidly growing anthropogenic source. In the future, the developing world will account for the largest share of transport GHG increases. Four basic components drive transportation energy consumption and GHG emissions: activities (A), mode share (S), fuel intensity (I) and fuel choice (F) (ASIF). Currently, the Kyoto Protocol's clean development mechanism (CDM) serves as the main international market-based tool designed to reduce GHG emissions from the developing world. Theoretically, the CDM has the dual purpose of helping developing countries achieve 'sustainable development' goals and industrialized countries meet their Kyoto emissions reduction commitments. This paper reviews overall CDM activities and transportation CDM activities to date and then presents findings from three case studies of transportation CDM possibilities examined with the ASIF framework in Santiago de Chile. The analysis suggests that bus technology switch (I) provides a fairly good project fit for the CDM, while options aimed at inducing mode share (S) to bicycle, or modifying travel demand via land use changes (ASI) face considerable challenges. The implications of the findings for the CDM and the 'post-Kyoto' world are discussed

Non-Photolithographic Manufacturing Processes for Micro-Channels Functioned by Micro-Contact-Printed SAMs

Science.gov (United States)

Saigusa, Hiroki; Suga, Yasuo; Miki, Norihisa

In this paper we propose non-photolithographic fabrication processes of micro-fluid channels with patterned SAMs (Self-Assembled-Monolayers). SAMs with a thiol group are micro-contact printed on a patterned Au/Ti layer, which is vapor-deposited through a shadow mask. Ti is an adhesion layer. Subsequently, the micro-channels are formed by bonding surface-activated PDMS onto the silicon substrate via a silanol group, producing a SAMs-functioned bottom wall of the micro-channel. No photolithographic processes are necessary and thus, the proposed processes are very simple, quick and low cost. The micro-reactors can have various functions associated with the micro-contact-printed SAMs. We demonstrate successful manufacturing of micro-reactors with two types of SAMs. The micro-reactor with patterned AUT (11-amino-1-undecanethiol) successfully trapped nano-particles with a carboxylic acid group, indicating that micro-contact-printed SAMs remain active after the manufacturing processes of the micro-reactor. AUT -functioned micro-channels are applicable to bioassay and to immobilize proteins for DNA arrays. ODT (1-octadecanethiol) makes surfaces hydrophobic with the methyl terminal group. When water was introduced into the micro-reactor with ODT-patterned surfaces, water droplets remained only in the hydrophilic areas where ODT was not patterned. ODT -functioned micro-channels are applicable to fluid handling.

Nuclear electricity and Canada's domestic response to the Kyoto Protocol: modeling the economics of alternative scenarios

International Nuclear Information System (INIS)

Kanudia, A.; Loulou, R.; Morrison, R.; Pendergast, D.

2001-03-01

Canada's National Climate Change Process has undertaken extensive analysis of the implications of implementing the greenhouse gas reduction commitments of the Kyoto Protocol. The results of work undertaken by the Issue Tables are documented on the National Climate Change Process Internet World Wide Web site. The final reports from the Analysis and Modeling Group have been interpreted by some as evidence that nuclear energy has no role to play in reducing greenhouse gas emissions in Canada as it is uneconomic. Yet nuclear energy is a proven means of generating electricity in Canada that does not emit greenhouse gases and that can be economic under a range of circumstances. This paper reviews the analysis and modeling work to establish the reasons for this apparent anomaly. It turns out that modeling of nuclear electricity production is highly constrained by some of the modeling input assumptions initiated with the modeling work of the Electricity Table. These constraints were subsequently carried through to modeling of the entire Canadian economy. The constraints are derived from consideration of historical political, social and economic limitations on nuclear energy deployment and development, which may be overcome in a greenhouse gas constrained Canada. These constraints, which were imposed on decision and construction time, are not technical in nature and do not realistically reflect newer technology. A key modeling scenario is re-evaluated to consider the effect of a shorter decision time and to reflect current nuclear industry capability with respect to construction time. We also take into account revised input parameters to account for a reduced capital cost system which is the goal of the CANDU designer. These changes result in the model choosing more nuclear energy as a least cost source of electricity. The increase in nuclear electricity is substantial for the scenarios that investigate the role of reduced capital cost nuclear power plant systems. The

We have measured environmental radiation dose rates in several Prefectures, such as Ai chi Prefecture, Gifu Prefecture, and Mie Prefecture, in central Japan. Recently, we measured the environmental radiation dose rates in Kyoto and Shiga Prefectures that are also located in central Japan with a car-borne survey system. At the time of measurement, Kyoto Prefecture (area: 4,613 km 2 ) had a total of 36 districts, and Shiga Prefecture (area: 3,387 km 2 ) a total of 26. Terrestrial gamma ray dose rates and secondary cosmic ray dose rates were measured by a 2 inches ψ x 2 inches NaI(Tl) scintillation counter and a handy-type altimeter (GPS eTrex Legend by Gamin), respectively. The following factors were taken into consideration the shielding effect of the car body, the effect of the road pavement, radon progeny borne by precipitation, and increases in tunnels and near the walls. Terrestrial gamma ray dose rates in Kyoto and Shiga Prefectures were estimated to be 51.7 ± 6.0 n Gy/h (district average: 52.4 ± 4.7 n Gy/h), 52.2 ± 10.5 n Gy/h (district average: 51.9 ± 8.1 n Gy/h), respectively. Secondary cosmic ray dose rates in Kyoto and Shiga Prefectures were 30.0 ± 0.6 n Gy/h (district average: 29.9 ±0.3 n Gy/h), 30.1 ± 0.3 n Gy/h (district average: 30.0 ± 0.2 n Gy/h), respectively. The environmental radiation dose rates due to the sum dose rates of terrestrial gamma ray and secondary cosmic ray in Kyoto and Shiga Prefectures were 81.7 ± 6.2 n Gy/h (district average: 82.3 ± 4.8 n Gy/h), 82.3 ± 10.6 n Gy/h (district average: 82.0 ± 8.1 n Gy/h), respectively. We confirmed that the environmental radiation dose rates in Kyoto and Shiga Prefectures mainly depended on the change of the terrestrial gamma ray dose rates, since the secondary cosmic ray dose rates had little change. Therefore, radiation dose-rate maps of the terrestrial gamma rays as well as maps of the environmental radiation dose-rate were drawn. (author)

Reflections on Sam Harris' "Free Will"

Directory of Open Access Journals (Sweden)

Daniel C. Dennett

2017-12-01

Full Text Available In his book Free Will Sam Harris tries to persuade us to abandon the morally pernicious idea of free will. The following contribution articulates and defends a more sophisticated model of free will that is not only consistent with neuroscience and introspection but also grounds a variety of responsibility that justifies both praise and blame, reward and punishment. This begins with the long lasting parting of opinion between compatibilists (who argue that free will can live comfortably with determinism and incompatibilists (who deny this. While Harris dismisses compatibilism as a form of theology, this article aims at showing that Harris has underestimated and misinterpreted compatibilism and at defending a more sophisticated version of compatibilism that is imprevious to Harris’ criticism.

During operations, NOvA produces between 5,000 and 7,000 raw files per day with peaks in excess of 12,000. These files must be processed in several stages to produce fully calibrated and reconstructed analysis files. In addition, many simulated neutrino interactions must be produced and processed through the same stages as data. To accommodate the large volume of data and Monte Carlo, production must be possible both on the Fermilab grid and on off-site farms, such as the ones accessible through the Open Science Grid. To handle the challenge of cataloging these files and to facilitate their off-line processing, we have adopted the SAM system developed at Fermilab. SAM indexes files according to metadata, keeps track of each file's physical locations, provides dataset management facilities, and facilitates data transfer to off-site grids. To integrate SAM with Fermilab's art software framework and the NOvA production workflow, we have developed methods to embed metadata into our configuration files, art files, and standalone ROOT files. A module in the art framework propagates the embedded information from configuration files into art files, and from input art files to output art files, allowing us to maintain a complete processing history within our files. Embedding metadata in configuration files also allows configuration files indexed in SAM to be used as inputs to Monte Carlo production jobs. Further, SAM keeps track of the input files used to create each output file. Parentage information enables the construction of self-draining datasets which have become the primary production paradigm used at NOvA. In this paper we will present an overview of SAM at NOvA and how it has transformed the file production framework used by the experiment. (paper)

The colombian private sector and climate change: the road from kyoto

International Nuclear Information System (INIS)

Olander, Jacob

1998-02-01

Because of its profound economic implications, the Kyoto Protocol merits careful study and active, continued participation on the part of the Colombian private sector. The article presents a brief summary of the main elements of the Protocol and its implications for Colombian business. For the business sector in Colombia, Joint implementation has been a key theme in motivating interest and participation on the issue of climate change. Now, after Kyoto, a new instrument has been created, the Clean Development Mechanism, which may permit international investment in forestry and energy projects that reduce greenhouse gas GHG- emissions. The Kyoto Protocol reduces the risk that Colombia need to assume new emissions reductions commitments, and in this new phase it is logical to focus on the opportunities created by the Protocol and the Framework Convention, especially the Clean Development Mechanism. Colombian business leaders should continue to participate actively in the international negotiations that will establish the rules of the game and in the development of private projects in industry, energy and forestry that capture

Ephrin A2 receptor (EphA2) plays a key role in cancer, it is up-regulated in several types of tumors and the process of ligand-induced receptor endocytosis, followed by degradation, is considered as a potential path to diminish tumor malignancy. Protein modulators of this mechanism are recruited at the cytosolic Sterile alpha motif (Sam) domain of EphA2 (EphA2-Sam) through heterotypic Sam-Sam associations. These interactions engage the C-terminal helix of EphA2 and close loop regions (the so called End Helix side). In addition, several studies report on destabilizing mutations in EphA2 related to cataract formation and located in/or close to the Sam domain. Herein, we analyzed from a structural point of view, one of these mutants characterized by the insertion of a novel 39 residue long polypeptide at the C-terminus of EphA2-Sam. A 3D structural model was built by computational methods and revealed partial disorder in the acquired C-terminal tail and a few residues participating in an α-helix and two short β-strands. We investigated by CD and NMR studies the conformational properties in solution of two peptides encompassing the whole C-terminal tail and its predicted helical region, respectively. NMR binding experiments demonstrated that these peptides do not interact relevantly with either EphA2-Sam or its interactor Ship2-Sam. Molecular dynamics (MD) simulations further indicated that the EphA2 mutant could be represented only through a conformational ensemble and that the C-terminal tail should not largely wrap the EphA2-Sam End-Helix interface and affect binding to other Sam domains.

We have investigated the effect of two different self-assembled monolayers (SAMs) on electrical characteristics of bilayer graphene (BLG)/n-Si Schottky diodes. Novel 4″bis(diphenylamino)-1, 1‧:3″-terphenyl-5‧ carboxylic acids (TPA) and 4,4-di-9H-carbazol-9-yl-1,1‧:3‧1‧-terphenyl-5‧ carboxylic acid (CAR) aromatic SAMs have been used to modify n-Si surfaces. Cyclic voltammetry (CV) and Kelvin probe force microscopy (KPFM) results have been evaluated to verify the modification of n-Si surface. The current-voltage (I-V) characteristics of bare and SAMs modified devices show rectification behaviour verifying a Schottky junction at the interface. The ideality factors (n) from ln(I)-V dependences were determined as 2.13, 1.96 and 2.07 for BLG/n-Si, BLG/TPA/n-Si and BLG/CAR/n-Si Schottky diodes, respectively. In addition, Schottky barrier height (SBH) and series resistance (Rs) of SAMs modified diodes were decreased compared to bare diode due to the formation of a compatible interface between graphene and Si as well as π-π interaction between aromatic SAMs and graphene. The CAR-based device exhibits better diode characteristic compared to the TPA-based device. Computational simulations show that the BLG/CAR system exhibits smaller energy-level-differences than the BLG/TPA, which supports the experimental findings of a lower Schottky barrier and series resistance in BLG/CAR diode.

The Kyoto Protocol : Canada's risky rush to judgement

International Nuclear Information System (INIS)

McKitrick, R.; Wigle, R.M.

2002-01-01

This paper outlined the 4 proposed policy options to implement the Kyoto Protocol in Canada and presented reasons why the Canadian timetable to ratify the Kyoto Protocol is an unrealistic and unsound policy. The Canadian Prime Minister will ask Parliament to ratify the agreement before the end of 2002 but the authors claim that before any decision regarding ratification is made, the government should cost out all relevant options, under all reasonable contingencies. For policy purposes, this paper focuses on reductions of carbon dioxide. Canada's obligation is to reduce them 6 per cent below 1990 levels by 2010, but because of economic growth, emissions among participating countries may be 30 per cent above their aggregate target. In addition, the withdrawal of the United States means that about two-thirds of the world's emissions are not covered by Kyoto. The first policy option involves the selling of emission permits covering about 80 per cent of domestic emitters. It results in 16 MT of domestic emissions reductions being accomplished and 128 MT of foreign permits being purchased. This first option is considered to be the least costly of the four. The second option relies on command-and-control measures in which 104 MT worth of new targeted measures are forced through. Although the government has not provided cost estimates for option 2, it is likely to be much more costly than option 1. The third option slightly adjusts the mix of permits trading and command-and-control measures, and distributes the permits freely instead of selling them. Only the large emitters are involved in the trading system, covering 40 per cent of domestic emission sources. The cost of emissions reductions would be lower than under option 1. The fourth and final option combines tradable permits systems in which only large emitters are involved, but where permits are distributed according to sectoral emission reduction costs, expected future emission growth rates as well as economic

We propose a novel framework for management of cancer survivorship: electronic patient Self-Assessment and Management (SAM). SAM is a framework for transfer of information to and from patients in such a way as to increase both the patient's and the health care provider's understanding of the patient's progress, and to help ensure that patient care follows best practice. Patients who participate in the SAM system are contacted by email at regular intervals and asked to complete validated questionnaires online. Patient responses on these questionnaires are then analyzed in order to provide patients with real-time, online information about their progress and to provide them with tailored and standardized medical advice. Patient-level data from the questionnaires are ported in real time to the patient's health care provider to be uploaded to clinic notes. An initial version of SAM has been developed at Memorial Sloan-Kettering Cancer Center (MSKCC) and the University of California, San Francisco (UCSF) for aiding the clinical management of patients after surgery for prostate cancer. Pilot testing at MSKCC and UCSF suggests that implementation of SAM systems are feasible, with no major problems with compliance (> 70% response rate) or security. SAM is a conceptually simple framework for passing information to and from patients in such a way as to increase both the patient's and the health care provider's understanding of the patient's progress, and to help ensure that patient care follows best practice.

In order to verify validation of that, CPC Axial Power Distribution is compared with Axial Power Distribution based on ICI every week. The difference between CPC Axial Power Distribution and Axial Power Distribution based on ICI increases according as fuels are burned. It is called CPC Axial Power Distribution Root Mean Square Error (CPC RMS Error). SAM and calibration of ex-core detector are important factors influencing the magnitude of the difference. According to vendor, the difference is limited by 8%. Otherwise, CPC penalty increases as many as difference increase. Therefore, KHNP developed Constrained Simulated Annealing Method (CSAM), which has better performance than that of Least Square Method (LSM), to calculate SAM constant. The CSA SAM contributed largely to maintain CPC operating margin. Somewhat, KHNP is developing the technology to be able to operate nuclear power plants for 24 month to optimize their efficiency. This paper shows trends of CPC RMS Error in a case of 24 months operation. Trends are based on data of a few OPR1000s under operation. It is data of OPR1000s that CSA SAM is applied. KHNP is developing the technology to extend operation cycle length in order to optimize the operation efficiency of OPR1000. To verify effect of extended operation cycle length on CPC, CPC Axial Power Distribution RMS Error in a case of 24 months operation was expected using operation data of six cycles in OPR1000. In cases that CPC Axial Power Distribution RMS Error exceeds threshold, operation margin is decreased due to CPC penalty. To prevent CPC operation margin from being decreased, improved method to calculate SAM or to calibrate ex-core detector is required. KHNP will consider the way to maintain CPC operation margin along with 24 month operation technology development, hereafter.

Beniwal, Neetu; Ameta, Gaurav; Chahar, Chandra Kumar

2017-05-01

To evaluate the prevalence and clinical features of Celiac disease among children with severe acute malnutrition (SAM). This prospective observational study was conducted in PBM Children Hospital, Bikaner from July 2012 through December 2013. All consecutively admitted children with SAM were recruited. All subjects were screened for Celiac disease by serological test for IgA-anti tissue Transglutaminase (IgA tTG) antibodies. All seropositive children underwent upper gastrointestinal endoscopy for small bowel biopsy for the confirmation. Clinical features of patients with and without celiac disease were compared. The sero-prevalence (IgA tTg positivity) of Celiac disease was found to be 15.38% while prevalence of biopsy confirmed Celiac disease was 14.42% among SAM children. Abdominal distension, diarrhea, anorexia, constipation, pain in abdomen, vitamin deficiencies, edema, clubbing and mouth ulcers were more common in patients of Celiac disease compared to patients without Celiac disease but the difference was statistically significant only for abdominal distension and pain abdomen. There is a high prevalence of Celiac disease in SAM. Screening for Celiac disease (especially in presence of pain abdomen and abdominal distension) should be an essential part of work-up in all children with SAM.

Pericyclic reactions—which proceed in a concerted fashion through a cyclic transition state—are among the most powerful synthetic transformations used to make multiple regioselective and stereoselective carbon-carbon bonds. They have been widely applied to the synthesis of biologically active complex natural products containing contiguous stereogenic carbon centres. Despite the prominence of pericyclic reactions in total synthesis, only three naturally existing enzymatic examples (the intramolecular Diels-Alder reaction, and the Cope and the Claisen rearrangements) have been characterized. Here we report a versatile S-adenosyl-L-methionine (SAM)-dependent enzyme, LepI, that can catalyse stereoselective dehydration followed by three pericyclic transformations: intramolecular Diels-Alder and hetero-Diels-Alder reactions via a single ambimodal transition state, and a retro-Claisen rearrangement. Together, these transformations lead to the formation of the dihydropyran core of the fungal natural product, leporin. Combined in vitro enzymatic characterization and computational studies provide insight into how LepI regulates these bifurcating biosynthetic reaction pathways by using SAM as the cofactor. These pathways converge to the desired biosynthetic end product via the (SAM-dependent) retro-Claisen rearrangement catalysed by LepI. We expect that more pericyclic biosynthetic enzymatic transformations remain to be discovered in naturally occurring enzyme ‘toolboxes’. The new role of the versatile cofactor SAM is likely to be found in other examples of enzyme catalysis.

The Porter-Whitesides Discrepancy: Revisiting Odd-Even Effects in Wetting Properties of n-Alkanethiolate SAMs

Directory of Open Access Journals (Sweden)

Zhengjia Wang

2015-12-01

Full Text Available This review discusses the Porter-Whitesides discrepancy in wetting properties of n-alkanethiolate self-assembled monolayers (SAMs. About 25 years ago, Whitesides and coworker failed to observe any odd-even effect in wetting, however, Porter and his coworker did, albeit in select cases. Most previous studies agreed with Whitesides’ results, suggesting the absence of the odd-even effect in hydrophobicity of n-alkanethiolate SAMs. Recent reports have, however, found the odd-even effect in hydrophobicity of n-alkanethiolate SAMs on smooth substrates, indicating that hydrophobicity, and analogous interfacial properties, of n-alkanethiolate SAMs significantly depends on the properties of substrate. Unfortunately, the Whitesides and Porter papers do not report on the quality of the surfaces used. Based on recent work, we inferred that the original discrepancy between Whitesides and Porter can be attributed to the quality of the surface. Odd-even effect of SAMs in charge transport, capacitance, friction, and SAM structure are also discussed in this review to inform the general discussion. The discrepancy between Porter's group and Whitesides’ group could be due to surface roughness, morphology, oxidation, and adventitious contaminants.

New Wistar Kyoto and spontaneously hypertensive rat transgenic models with ubiquitous expression of green fluorescent protein

Full Text Available The Wistar Kyoto (WKY rat and the spontaneously hypertensive (SHR rat inbred strains are well-established models for human crescentic glomerulonephritis (CRGN and metabolic syndrome, respectively. Novel transgenic (Tg strains add research opportunities and increase scientific value to well-established rat models. We have created two novel Tg strains using Sleeping Beauty transposon germline transgenesis, ubiquitously expressing green fluorescent protein (GFP under the rat elongation factor 1 alpha (EF1a promoter on the WKY and SHR genetic backgrounds. The Sleeping Beauty system functioned with high transgenesis efficiency; 75% of new rats born after embryo microinjections were transgene positive. By ligation-mediated PCR, we located the genome integration sites, confirming no exonic disruption and defining a single or low copy number of the transgenes in the new WKY-GFP and SHR-GFP Tg lines. We report GFP-bright expression in embryos, tissues and organs in both lines and show preliminary in vitro and in vivo imaging data that demonstrate the utility of the new GFP-expressing lines for adoptive transfer, transplantation and fate mapping studies of CRGN, metabolic syndrome and other traits for which these strains have been extensively studied over the past four decades.

Greenhouse gas emission trends and projections in Europe 2012. Tracking progress towards Kyoto and 2020 targets

At the end of 2011, almost all European countries were on track towards their Kyoto targets for 2008-2012. The EU-15 also remained on track to achieve its Kyoto target. Italy, however, was not on track. Spain plans to acquire a large quantity of Kyoto units through the KP's flexible mechanisms to achieve its target. With emission caps already set for the economic sectors under the EU Emissions Trading Scheme (EU ETS), emissions reductions during 2012 in the sectors outside the EU ETS together with reductions by carbon sinks will set the frame for how many Kyoto units Member States need to acquire to reach their individual targets. Hence, both the development and delivery of adequate plans to acquire enough Kyoto credits is becoming increasingly important. ETS emissions from 2008 to 2011 were on average 5 % below these caps, which results in an oversupply of allowances. The EU ETS is undergoing important changes in view of the third trading phase from 2013 to 2020. Most EU Member States project that in 2020, their emissions outside the EU ETS will be lower than their national targets set under the Climate and Energy Package. However, further efforts will be necessary to achieve longer term reductions. (Author)

Modelling Energy Systems and International Trade in CO2 Emission Quotas - The Kyoto Protocol and Beyond

International Nuclear Information System (INIS)

Persson, Tobias A.

2002-01-01

A transformation of the energy system in the 21st century is required if the CO 2 concentration in the atmosphere should be stabilized at a level that would prevent dangerous anthropogenic interference with the climate system. The industrialized countries have emitted most of the anthropogenic CO 2 released to the atmosphere since the beginning of the industrial era and still account for roughly two thirds of global fossil fuel related CO 2 emissions. Industrial country CO 2 emissions on a per capita basis are roughly five to ten times higher than those of developing countries. However, a global atmospheric CO 2 concentration target of 450 ppm, if adopted would require that global average per capita CO 2 emissions by the end of this century have to be comparable to those of developing countries today. The industrialized countries would have to reduce their emissions substantially and the emissions in developing countries could not follow a business-as-usual scenario. The transformation of the energy system and abatement of CO 2 emissions would need to occur in industrialized and developing countries. Energy-economy models have been developed to analyze of international trading in CO 2 emission permits. The thesis consists of three papers. The cost of meeting the Kyoto Protocol is estimated in the first paper. The Kyoto Protocol, which defines quantitative greenhouse gas emission commitments for industrialized countries over the period 2008-2012, is the first international agreement setting quantitative goals for abatement of CO 2 emissions from energy systems. The Protocol allows the creation of systems for trade in emission permits whereby countries exceeding their target levels can remain in compliance by purchasing surplus permits from other developed countries. However, a huge carbon surplus, which has been christened hot air, has been created in Russia and Ukraine since 1990 primarily because of the contraction of their economies.

An assessment of the economic and environmental implications for Canada of the Kyoto Protocol

International Nuclear Information System (INIS)

2000-11-01

The National Climate Change Process was launched in April 1998 to examine the feasibility and implications of Canada's commitment to the Kyoto Protocol. The Analysis Modelling Group (AMG) was designated to assess the economic and environmental consequences for Canada in achieving the target. This report summarizes the analytical approach, the assumptions, the results and the main findings of the AMG's efforts to analyse the macro-/micro-economic, social, health and environmental implications of the Kyoto Protocol. The role of the AMG was to provide policymakers with guidance on some issues such as the economic implications of different broad policy approaches, the potential costs of greater access to the Kyoto flexibility mechanisms, the sectoral and regional distributions of emissions reductions, and the degree to which Canada's competitive position could be affected by the achievement of the Protocol. The relative importance of greenhouse gas reduction was also discussed along with a review of actions that offer significant potential for emissions reductions. The AMG examined five policy packages or Paths which are differentiated by different degrees of reliance on specific measures and tradable permit systems and by the imposition of sectoral versus national targets. It was concluded that at the national level, attainment of the target results in sustained, long-term negative economic impacts. In the long run, the reduction in gross domestic product (GDP) relative to the business-as-usual case, ranges from 0 to 3 per cent depending on the path-scenario combination. It was emphasized that it is important to provide perspective on these estimates. 37 refs., 64 figs

The EphA2 receptor controls diverse physiological and pathological conditions and its levels are often upregulated in cancer. Targeting receptor overexpression, through modulation of endocytosis and consequent degradation, appears to be an appealing strategy for attacking tumor malignancy. In this scenario, the Sam domain of EphA2 plays a pivotal role because it is the site where protein regulators of endocytosis and stability are recruited by means of heterotypic Sam-Sam interactions. Because EphA2-Sam heterotypic complexes are largely based on electrostatic contacts, we have investigated the possibility of attacking these interactions with helical peptides enriched in charged residues. Several peptide sequences with high predicted helical propensities were designed, and detailed conformational analyses were conducted by diverse techniques including NMR, CD, and molecular dynamics (MD) simulations. Interaction studies were also performed by NMR, surface plasmon resonance (SPR), and microscale thermophoresis (MST) and led to the identification of two peptides capable of binding to the first Sam domain of Odin. These molecules represent early candidates for the generation of efficient Sam domain binders and antagonists of Sam-Sam interactions involving EphA2. © 2016 Wiley-VCH Verlag GmbH & Co.

Full Text Available Climate change is one of the most important challenges that humanity faces in the 21st century, which is seriously considered by the European Union. In this context, the objective of this paper is to analyze the extent to which the EU has fulfilled its obligations in the first commitment period of the Kyoto Protocol, and also to expose the obligations stipulated for the second period (2013-2020. The approach is to display in the first part of the work the fulfillment by the European Union of the Kyoto objectives, and in the second part, to analyze the successful implementation in the EU of the flexible mechanisms provided through the Protocol.

SAM-CE, Time-Dependent 3-D Neutron Transport, Gamma Transport in Complex Geometry by Monte-Carlo

International Nuclear Information System (INIS)

2003-01-01

1 - Nature of physical problem solved: The SAM-CE system comprises two Monte Carlo codes, SAM-F and SAM-A. SAM-F supersedes the forward Monte Carlo code, SAM-C. SAM-A is an adjoint Monte Carlo code designed to calculate the response due to fields of primary and secondary gamma radiation. The SAM-CE system is a FORTRAN Monte Carlo computer code designed to solve the time-dependent neutron and gamma-ray transport equations in complex three-dimensional geometries. SAM-CE is applicable for forward neutron calculations and for forward as well as adjoint primary gamma-ray calculations. In addition, SAM-CE is applicable for the gamma-ray stage of the coupled neutron-secondary gamma ray problem, which may be solved in either the forward or the adjoint mode. Time-dependent fluxes, and flux functionals such as dose, heating, count rates, etc., are calculated as functions of energy, time and position. Multiple scoring regions are permitted and these may be either finite volume regions or point detectors or both. Other scores of interest, e.g., collision and absorption densities, etc., are also made. 2 - Method of solution: A special feature of SAM-CE is its use of the 'combinatorial geometry' technique which affords the user geometric capabilities exceeding those available with other commonly used geometric packages. All nuclear interaction cross section data (derived from the ENDF for neutrons and from the UNC-format library for gamma-rays) are tabulated in point energy meshes. The energy meshes for neutrons are internally derived, based on built-in convergence criteria and user- supplied tolerances. Tabulated neutron data for each distinct nuclide are in unique and appropriate energy meshes. Both resolved and unresolved resonance parameters from ENDF data files are treated automatically, and extremely precise and detailed descriptions of cross section behaviour is permitted. Such treatment avoids the ambiguities usually associated with multi-group codes, which use flux

Turkish support to Kyoto Protocol: A reality or just an illusion

International Nuclear Information System (INIS)

Erdogdu, Erkan

2010-01-01

The long-term increase in Earth's temperature is known as the global warming or the greenhouse effect. Taking into account the fact that the ice age only involved a global temperature variation of around 4 C, it is clear climate change is arguably one of the greatest environmental threats the world is facing today. The impacts of disruptive change leading to catastrophic events such as storms, droughts, sea level rise and floods are already being felt across the world. In this context, the signing of the Kyoto Protocol in 1997 has been argued to be a historic step in reversing the inexorable increase in the emission of the greenhouse gases. The primary achievement of the Protocol has been so-called commitment of countries referred in the Annex I of the Protocol to reduce their emission of GHGs some 5% below their country specific 1990 level. On February 5, 2009, Turkish Parliament ratified an agreement to sign the Kyoto Protocol after intense pressure from both the European Union and international environmental organizations; however, so far it has not taken any step to bring about real reductions in emissions. In short, Turkey simply signed but ignored the Protocol. Present paper investigates Turkish position vis-a-vis Kyoto Protocol and critically questions Turkish policies in that area. (author)

Monovalent Cation Activation of the Radical SAM Enzyme Pyruvate Formate-Lyase Activating Enzyme.

Pyruvate formate-lyase activating enzyme (PFL-AE) is a radical S-adenosyl-l-methionine (SAM) enzyme that installs a catalytically essential glycyl radical on pyruvate formate-lyase. We show that PFL-AE binds a catalytically essential monovalent cation at its active site, yet another parallel with B 12 enzymes, and we characterize this cation site by a combination of structural, biochemical, and spectroscopic approaches. Refinement of the PFL-AE crystal structure reveals Na + as the most likely ion present in the solved structures, and pulsed electron nuclear double resonance (ENDOR) demonstrates that the same cation site is occupied by 23 Na in the solution state of the as-isolated enzyme. A SAM carboxylate-oxygen is an M + ligand, and EPR and circular dichroism spectroscopies reveal that both the site occupancy and the identity of the cation perturb the electronic properties of the SAM-chelated iron-sulfur cluster. ENDOR studies of the PFL-AE/[ 13 C-methyl]-SAM complex show that the target sulfonium positioning varies with the cation, while the observation of an isotropic hyperfine coupling to the cation by ENDOR measurements establishes its intimate, SAM-mediated interaction with the cluster. This monovalent cation site controls enzyme activity: (i) PFL-AE in the absence of any simple monovalent cations has little-no activity; and (ii) among monocations, going down Group 1 of the periodic table from Li + to Cs + , PFL-AE activity sharply maximizes at K + , with NH 4 + closely matching the efficacy of K + . PFL-AE is thus a type I M + -activated enzyme whose M + controls reactivity by interactions with the cosubstrate, SAM, which is bound to the catalytic iron-sulfur cluster.

The Potential of the Market for the Kyoto Mechanisms

International Nuclear Information System (INIS)

Zhang, Z.X.

2000-01-01

The Kyoto Protocol is the first international environmental agreement to set legally binding greenhouse gas (GHG) emissions targets and timetables for Annex I countries. It incorporates emissions trading and two project-based flexibility mechanisms, namely joint implementation (JI) and the clean development mechanism (CDM) to help Annex I countries to meet their Kyoto targets at a lower overall cost. The extent to which their compliance cost can be lowered depends on the size of the market for all three flexibility mechanisms under the Protocol. This article estimates the size of such a market and demonstrates that restrictions on the use of flexibility mechanisms not only reduce potential of the Annex I countries' efficiency gains, but are furthermore not beneficial to developing countries since they restrict the total financial flows to developing countries under the CDM. Thus, from the perspective of husbanding the world's limited resources, the fewer the restrictions on the use of flexibility mechanisms, the greater are the gains from their use

This article presents a brief historical record concerning the Brazilian institutional arrangement given to the Kyoto Protocol and, based on the Brazilian emissions profile, discusses general perspectives to the use of the CDM, mainly in projects involving co-generation in the agricultural sector. It is observed high uncertainty about the liquidity and development of the carbon credit market, above all, with reference to the definition of the second period of the Kyoto Protocol commitments. Even so, with the consolidation of the institutional environment, the carbon credit market must become favorable to the projects of co-generation in agricultural sector, especially in countries as Brazil.

Among the different possibilities to slow down the increase of greenhouse gas emissions, several participants of the Kyoto conference (December 11, 1997) held the nuclear power resort in a good position. This short paper reports on some extracts of talks given during the conference by participants who take a definite position in favour of the development of nuclear power: FORATOM (European Atomic Forum), Nuclear Energy Institute (US), Japan Atomic Industrial Forum, the Uranium Institute, WONUC (World Council of Nuclear Workers) and SFEN (French Society of Nuclear Energy).

Highlights: • n-Alkyltrimethoxysilanes with various chain lengths were self-assembled on silicon. • Effect of alkyl chain lengths (C6, C12, or C18) on the SAMs was investigated. • Surface roughness of the SAMs decreased with increasing the alkyl chain lengths. • The C 12 -SAM possessed superior friction reduction and wear resistance. - Abstract: It is well known that the self-assembled organic molecules on a solid surface exhibit the friction-reducing performance. However, the effect of the molecular size of the self-assembled organic molecules has not been established. In the present work, self-assembled monolayers (SAMs) of n-alkyltrimethoxysilanes with different alkyl chain lengths (C 6 , C 12 , or C 18 ) were fabricated on silicon substrate. The water contact angles of the SAMs increased from 26.8° of the hydroxylated silicon substrate to near 60° after self-assembly. The atomic force microscopy (AFM) analysis results showed that the mean roughness (R a ) of the SAMs decreased with increasing the alkyl chain length. The tribological properties of the SAMs sliding against Al 2 O 3 ball were evaluated on an UMT-2 tribometer, and the worn surfaces of the samples were analyzed by means of Nano Scratch Tester and surface profilometry. It was found that lowest friction coefficient and smallest width of wear were achieved with the SAMs of C 12 alkyl chain (C 12 -SAM). The superior friction reduction and wear resistance of the SAMs in comparison with the bare silicon substrate are attributed to good adhesion of the self-assembled films to the substrate, especially the C 12 -SAM with desirable alkyl chain length.

Considering WTO law in the design of climate change regimes beyond Kyoto

Science.gov (United States)

Gaines, Sanford E.

2009-11-01

This article describes the most important provisions of World Trade Organization (WTO) agreements that should be considered in designing laws and regulations under likely post-Kyoto climate change mitigation regimes. The Kyoto Protocol and the expected post-Kyoto international climate agreement depend on national measures to implement market-based mitigation measures. This market strategy promotes international exchanges of goods, investments, and services such as cross-border trading of credits for emissions reductions and transnational financing for projects that avoid emissions through the Clean Development Mechanism. Moreover, the United States and other countries, concerned over "leakage" of greenhouse gas (GHG) emissions through relocation of industry to other countries coupled with political worry over manufacturing competitiveness, have proposed national climate legislation containing border adjustments on imported goods or implicit subsidies for national producers, raising additional WTO considerations. The article assesses the likely effectiveness of such trade-related measures in achieving climate change mitigation goals and the potential trade policy infringements and trade distortions that they might bring about. Alternative strategies for achieving GHG mitigation goals in closer conformity with WTO law and policy will be suggested.

Full Text Available An accelerator-driven system consists of a subcritical reactor and a controllable external neutron source. The reactor in an accelerator-driven system can sustain fission reactions in a subcritical state using an external neutron source, which is an intrinsic safety feature of the system. The system can provide efficient transmutations of nuclear wastes such as minor actinides and long-lived fission products and generate electricity. Recently at Kyoto University Research Reactor Institute (KURRI; Kyoto, Japan, a series of reactor physics experiments was conducted with the Kyoto University Critical Assembly and a Cockcroft–Walton type accelerator, which generates the external neutron source by deuterium–tritium reactions. In this paper, neutronic analyses of a series of experiments have been re-estimated by using the latest Monte Carlo code and nuclear data libraries. This feasibility study is presented through the comparison of Monte Carlo simulation results with measurements.

Market-based implementation of Kyoto commitments: how the financial/insurance sector can support industry

International Nuclear Information System (INIS)

Knoepfel, Ivo

1999-01-01

The implementation of the Kyoto Protocol in the context of the Framework Convention on Climate Change will probably lead to economic winners and losers in various sectors of the economy. Especially carbon intensive industries will need to develop hedging strategies to prevent potential negative effects and to optimise market opportunities. Such strategies can be based on technological innovation, market and product diversification, and on financial/legal offsets. The Kyoto Protocol has introduced new market-based instruments, which can, in a near future provide such hedging opportunities. These include joint implementation, the so-called clean development mechanism, and international emissions trading. The financial services and insurance sector are the natural partners of industry in designing tailored hedging strategies. It is recommended that industry, financial services and insurance companies take a more proactive role in further developing the market-based instruments established by the Kyoto Protocol. (Author)

Fabrication and Surface Properties of Composite Films of SAM/Pt/ZnO/SiO 2

KAUST Repository

Yao, Ke Xin

2008-12-16

Through synthetic architecture and functionalization with self-assembled monolayers (SAMs), complex nanocomposite films of SAM/Pt/ZnO/SiO2 have been facilely prepared in this work. The nanostructured films are highly uniform and porous, showing a wide range of tunable wettabilities from superhydrophilicity to superhydrophobicity (water contact angles: 0° to 170°). Our approach offers synthetic flexibility in controlling film architecture, surface topography, coating texture, crystallite size, and chemical composition of modifiers (e.g., SAMs derived from alkanethiols). For example, wettability properties of the nanocomposite films can be finely tuned with both inorganic phase (i.e., ZnO/SiO2 and Pt/ZnO/SiO2) and organic phase (i.e., SAMs on Pt/ZnO/SiO2). Due to the presence of catalytic components Pt/ZnO within the nanocomposites, surface reactions of the organic modifiers can further take place at room temperature and elevated temperatures, which provides a means for SAM formation and elimination. Because the Pt/ZnO forms an excellent pair of metal-semiconductors for photocatalysis, the anchored SAMs can also be modified or depleted by UV irradiation (i.e., the films possess self-cleaning ability). Potential applications of these nanocomposite films have been addressed. Our durability tests also confirm that the films are thermally stable and structurally robust in modification- regeneration cycles. © 2008 American Chemical Society.

Necrosis-Driven Systemic Immune Response Alters SAM Metabolism through the FOXO-GNMT Axis

Directory of Open Access Journals (Sweden)

Fumiaki Obata

2014-05-01

Full Text Available Sterile inflammation triggered by endogenous factors is thought to contribute to the pathogenesis of acute and chronic inflammatory diseases. Here, we demonstrate that apoptosis-deficient mutants spontaneously develop a necrosis-driven systemic immune response in Drosophila and provide an in vivo model for studying the organismal response to sterile inflammation. Metabolomic analysis of hemolymph from apoptosis-deficient mutants revealed increased sarcosine and reduced S-adenosyl-methionine (SAM levels due to glycine N-methyltransferase (Gnmt upregulation. We showed that Gnmt was elevated in response to Toll activation induced by the local necrosis of wing epidermal cells. Necrosis-driven inflammatory conditions induced dFoxO hyperactivation, leading to an energy-wasting phenotype. Gnmt was cell-autonomously upregulated by dFoxO in the fat body as a possible rheostat for controlling energy loss, which functioned during fasting as well as inflammatory conditions. We propose that the dFoxO-Gnmt axis is essential for the maintenance of organismal SAM metabolism and energy homeostasis.

Environmental and economic effects of post-Kyoto carbon regimes. Results of simulations with the global model GINFORS

International Nuclear Information System (INIS)

Lutz, Christian; Meyer, Bernd

2009-01-01

Using the extensive and disaggregated global GINFORS model, consequences of different possible post-Kyoto regimes on the German and European economy and other major economies in the medium run until 2020 are depicted. The approach is very extensive and detailed in comparison to already existing analyses: this holds for the number of explicitly modelled countries (50 and 2 regions) and 41 economic sectors, input-output tables, the bilateral trade flows, the detailed coverage of behavioural parameters, the coverage of energy balances and CO 2 emissions as well as for the number and precise economic-political design of simulation runs. Global emissions will double until 2030 compared to 1990 levels without the existence of a far-reaching climate regime after 2012. A unilateral commitment of the EU would only be a 'drop in the bucket', which solely strengthens the credibility of the EU in international negotiations. A stabilisation of global emissions in 2020 compared to 2010, which is consistent with the 2 target of the EU can only be achieved, if all developed and at least the large emerging economies participate and if all possible existing market-ready reduction technologies are used.

The SAM-CE Monte Carlo system (for three dimensional neutron, gamma ray and electron transport) has been expanded to include a reactivity capability. The implemented code modifications have effected the following improvements: (a) Doppler broadening of ENDF/B-IV based nuclear data (including fission); (b) probability table representation for the unresolved resonance range; (c) utilization of thermal scattering law data for the moderator; (d) free gas model in the absence of thermal scattering law data; (e) generalization of the nuclear element data tape structure to facilitate data management; (f) generalization of data management routines; (g) extension of the SAM-CE Complex Combinatorial Geometry capability to facilitate treatment of hexagonal lattices; (h) simultaneous use of 4 different eigenvalue estimators; (i) estimation of the eigenfunction in user prescribed spatial domains; and (j) variance reduction via stratification of source (position, energy, direction) and absorption (based on a quota sampling technique), as well as optional suppression of absorption. The new coding has undergone extensive testing, both specific (via drivers and idealized data) and integral (via comparison with previous computations). Base data have been examined for internal consistency and checked for reasonableness. A documented TRX-1 benchmark calculation has been performed. Agreement with other calculations, as well as with experiment, has served to validate the reactivity mode of SAM-CE. Further refinement of the cross section data processing component of SAM-CE (i.e., SAM-X) is suggested

Histological gastritis is associated with gastric cancer, but its diagnosis requires biopsy. Many classifications of endoscopic gastritis are available, but not all are useful for risk stratification of gastric cancer. The Kyoto Classification of Gastritis was proposed at the 85th Congress of the Japan Gastroenterological Endoscopy Society. This cross-sectional study evaluated the usefulness of the Kyoto Classification of Gastritis for risk stratification of gastric cancer. From August 2013 to September 2014, esophagogastroduodenoscopy was performed and the gastric findings evaluated according to the Kyoto Classification of Gastritis in a total of 4062 patients. The following five endoscopic findings were selected based on previous reports: atrophy, intestinal metaplasia, enlarged folds, nodularity, and diffuse redness. A total of 3392 patients (1746 [51%] men and 1646 [49%] women) were analyzed. Among them, 107 gastric cancers were diagnosed. Atrophy was found in 2585 (78%) and intestinal metaplasia in 924 (27%). Enlarged folds, nodularity, and diffuse redness were found in 197 (5.8%), 22 (0.6%), and 573 (17%), respectively. In univariate analyses, the severity of atrophy, intestinal metaplasia, diffuse redness, age, and male sex were associated with gastric cancer. In a multivariate analysis, atrophy and male sex were found to be independent risk factors. Younger age and severe atrophy were determined to be associated with diffuse-type gastric cancer. Endoscopic detection of atrophy was associated with the risk of gastric cancer. Thus, patients with severe atrophy should be examined carefully and may require intensive follow-up. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

World CO_2-energy emissions balance and impacts of the Kyoto Protocol in Europe

International Nuclear Information System (INIS)

Chateau, Bertrand

2005-01-01

industrial sector and the other sectors do not emit more in 2003 than in 1990. All large countries and zones of the Annex B, except the CIS and Eastern Europe countries, resolutely deviate from the Kyoto objectives; relatively, the UE-15 performs better than the other zones. Despite the Russian hot air, global emissions from the Annex B countries are 1.5 GtCO_2 higher than the Kyoto objectives for 2003. Only 5 countries are less than 12% from the objective in 2003: Germany, France, Greece, UK, Sweden. 4 countries are more than 35% higher from the objective: Austria, Spain, Ireland, Luxemburg. There are 3 principal drivers explaining emissions dynamics: Economic and demographic growths generate higher emissions; Emissions/capita disparities are also linked to energy fuel mix, in particular for electricity generation: this fuel mix evolution partly explains the differences among countries performance vs. Kyoto; The various sectors emitting CO_2-energy weight unequally within total emissions: differences in dynamics by sector partly explain the evolutions observed. The natural gas penetration and relative coal receding slow the emissions increase and is even more accentuated in Europe. The electric sector and transport, main drivers of world emissions increase. Situations and evolutions are more contrasted in Europe for the energy sector. Contrasted positions in the industry sector vs. CO_2 emissions (including process) within the Annex B countries. A similar contrast is observed in the EU. Anticipation of carbon prices: a market simulated by the POLES model, based on carbon supply and offer. In particular, the POLES model assesses the effect of the USA withdrawal and Russian 'hot air' on the carbon market. The implementation of the EU ETS will lead to an increase in gas prices. Energy prices will be more affected by carbon price in the industry sector than in other sectors

It is well known that the self-assembled organic molecules on a solid surface exhibit the friction-reducing performance. However, the effect of the molecular size of the self-assembled organic molecules has not been established. In the present work, self-assembled monolayers (SAMs) of n-alkyltrimethoxysilanes with different alkyl chain lengths (C6, C12, or C18) were fabricated on silicon substrate. The water contact angles of the SAMs increased from 26.8° of the hydroxylated silicon substrate to near 60° after self-assembly. The atomic force microscopy (AFM) analysis results showed that the mean roughness (Ra) of the SAMs decreased with increasing the alkyl chain length. The tribological properties of the SAMs sliding against Al2O3 ball were evaluated on an UMT-2 tribometer, and the worn surfaces of the samples were analyzed by means of Nano Scratch Tester and surface profilometry. It was found that lowest friction coefficient and smallest width of wear were achieved with the SAMs of C12 alkyl chain (C12-SAM). The superior friction reduction and wear resistance of the SAMs in comparison with the bare silicon substrate are attributed to good adhesion of the self-assembled films to the substrate, especially the C12-SAM with desirable alkyl chain length.

1998-01-01

The compatibility of the Kyoto Protocol flexible instruments and the lessons that can be learned form the AIJ-phase (AIJ stands for Activities Implemented Jointly) are discussed. The key point to be made is that there may be various applications of flexible instruments which can create situations where the various instruments would crowd out each other. On the other hand, applying flexible instruments may create a leverage for Parties in terms of achieving domestic environmental objectives. In addition, several issues related to the implementation of Joint Implementation (JI) , Clean Development Mechanism (CDM) and international emissions trading are discussed. The issues concern mainly those that have been included in the working programme on flexible instruments for CoP4 and CoP5 (CoP stands for Convention of Parties). As such the report discusses the consequences of possible negotiations outcomes at CoP for the effectiveness of flexible instruments, Parties' capabilities to achieve their Kyoto Protocol commitments cost-effectively, and the role of the private sector on the national and international credits markets(s). 106 refs

An important goal of upcoming missions to Mars is to understand if life could have developed there. The task of the Sample Analysis at Mars (SAM) suite of instruments [1] and the other Curiosity investigations [2] is to move us steadily toward that goal with an assessment of the habitability of our neighboring planet through a series of chemical and geological measurements. SAM is designed to search for organic compounds and inorganic volatiles and measure isotope ratios. Other instruments on Curiosity will provide elemental analysis and identify minerals. SAM will analyze both atmospheric samples and gases evolved from powdered rocks that may have formed billions of years ago with Curiosity providing access to interesting sites scouted by orbiting cameras and spectrometers.

A magnesium-induced triplex pre-organizes the SAM-II riboswitch.

Directory of Open Access Journals (Sweden)

Susmita Roy

2017-03-01

Full Text Available Our 13C- and 1H-chemical exchange saturation transfer (CEST experiments previously revealed a dynamic exchange between partially closed and open conformations of the SAM-II riboswitch in the absence of ligand. Here, all-atom structure-based molecular simulations, with the electrostatic effects of Manning counter-ion condensation and explicit magnesium ions are employed to calculate the folding free energy landscape of the SAM-II riboswitch. We use this analysis to predict that magnesium ions remodel the landscape, shifting the equilibrium away from the extended, partially unfolded state towards a compact, pre-organized conformation that resembles the ligand-bound state. Our CEST and SAXS experiments, at different magnesium ion concentrations, quantitatively confirm our simulation results, demonstrating that magnesium ions induce collapse and pre-organization. Agreement between theory and experiment bolsters microscopic interpretation of our simulations, which shows that triplex formation between helix P2b and loop L1 is highly sensitive to magnesium and plays a key role in pre-organization. Pre-organization of the SAM-II riboswitch allows rapid detection of ligand with high selectivity, which is important for biological function.

Do foreign direct investment and renewable energy consumption affect the CO2 emissions? New evidence from a panel ARDL approach to Kyoto Annex countries.

Science.gov (United States)

Mert, Mehmet; Bölük, Gülden

2016-11-01

This study examines the impact of foreign direct investment (FDI) and the potential of renewable energy consumption on carbon dioxide (CO 2 ) emissions in 21 Kyoto countries using an unbalanced panel data. For this purpose, Environmental Kuznets Curve (EKC) hypothesis was tested using panel cointegration analysis. Panel causality tests show that there are significant long-run causalities from the variables to carbon emissions, renewable energy consumption, fossil fuel energy consumption and inflow foreign direct investments. The results of our model support the pollution haloes hypothesis which states that FDI brings in clean technology and improves the environmental standards. However, an inverted U-shaped relationship (EKC) was not supported by the estimated model for the 21 Kyoto countries. This means that economic growth cannot ensure environmental protection itself or environmental goals cannot await economic growth. Another important finding is that renewable energy consumption decreases carbon emissions. Based on the empirical results, some important policy implications emerge. Kyoto countries should stimulate the FDI inflows and usage of renewable energy consumption to mitigate the air pollution and meet the emission targets. This paper provides new insights into environment and energy policies through FDI inclusion.

Greenhouse gas emission trends and projections in Europe 2011. Tracking progress towards Kyoto and 2020 targets

At the end of 2010, the EU-15 was on track to achieve its Kyoto target but three EU-15 Member States (Austria, Italy and Luxembourg) were not on track to meet their burden-sharing targets. These countries must therefore seriously consider further action to ensure compliance, in particular revising their plans on using flexible mechanisms. Among the EEA member countries outside the EU, Liechtenstein and Switzerland were not on track to achieve their Kyoto target at the end of 2009. All other European countries are on track to meet their targets, either based on domestic emissions only or with the assistance of Kyoto mechanisms. The economic recession had a significant impact on the EU's total greenhouse gas (GHG) emission trends but a more limited effect on progress towards Kyoto targets. This is because emissions in the sectors covered by the EU Emissions Trading Scheme (ETS), which were most affected by the crisis, do not affect Kyoto compliance once ETS caps have been set. With existing national measures, Member States do not project enough emission reductions for the EU to meet its unilateral 20 % reduction commitment in 2020. Additional measures currently planned by Member States will help further reduce emissions but will be insufficient to achieve the important emission cuts needed in the longer term. By 2020 Member States must enhance their efforts to reduce emissions in non-EU ETS sectors, such as the residential, transport or agriculture sectors, where legally binding national targets have been set under the EU's 2009 climate and energy package.

On the Consequences of the U.S. Withdrawal from the Kyoto/Bonn Protocol

Buchner, B.; Cersosimo, I.; Carraro, C.

2001-12-01

The US decision not to ratify the Kyoto Protocol and the recent outcomes of the Bonn and Marrakech Conferences of the Parties have important implications for both the effectiveness and the efficiency of future climate policies. Among these implications, those related with technical change and with the functioning of the international market for carbon emissions are particularly relevant, because these variables have the largest impact on the overall abatement cost to be borne by Annex B countries in the short and in the long run. This paper analyses the consequences of the US decision to withdraw from the Kyoto/Bonn Protocol both on technological innovation and on the price of emission permits (and, as a consequence, on abatement costs). A first goal is to assess the impact of the US defection on the price of permits and compliance costs when technological innovation and diffusion is taken into account (the model embodies international technological spillovers). A second goal is to understand for what reasons in the presence of endogenous and induced technical change the reduction of the price of permits is lower than in most empirical analyses recently circulated. A third goal is to assess the role of Russia in climate negotiations, its increased bargaining power and its eventual incentives to follow the US defections

From small to insignificant. Climate impact of the Kyoto Protocol with and without US

American president George W. Bush has declared that he will not ask the Senate to ratify the Kyoto Protocol. This commentary explores the potential impact of implementing the Kyoto Protocol without the participation of the United States. Because, in practice, the United States would have taken on a relatively large share of the Protocol's abatement commitments, we conclude that implementing the Protocol without the participation of United States will lead to significantly less reductions in global emissions. The international permit price will be considerably lower if the United States does not participate. (author)

Severe accident management (SAM), operator training and instrumentation capabilities - Summary and conclusions

for SAM. In most cases existing instrumentation should be able to provide usable information. Additional instrumentation requirements may arise from particular accident management measures implemented in some plants. In any case, depending on the time frame where the instrumentation should be relied upon, it should be assessed whether it is likely to survive the harsh environmental conditions it will be exposed to. Though uncertainties still remain in the understanding of some severe accident phenomena, this should not be considered as a de-facto impediment against using simplified models both as operator aids in the course of an accident and as an option of a simulator severe accident mathematical model. These tools, however, should be based on state-of-the-art physics and calibrated using more sophisticated codes. Having the capability for periodic assessment of trends and predictions against real plant parameter evolution, and subsequent correction, is also advised for such tools. Being prepared for the unexpected is the major objective pursued in training, especially when capabilities extend into severe accident situations. When training for severe accidents is contemplated, skill-oriented sessions should be emphasized as they allow evaluating operator reactions in highly perturbed situations. However, it is also advised to increase operator awareness in case of severe accident situations through tailored sessions stressing knowledge of basic phenomena involved in degraded situations. Though computer-based training could well prevail in the long run, table-top exercises as currently implemented by many utilities also bring extremely valuable results

Beginnings of the study of Western sciences, "Rangaku," in Kyoto and Osaka in the late 18th century are reviewed. Profiles and achievements of several active learners are briefly described; they include Koishi Genzui (Osaka-Kyoto), Tsuji Ranshitsu (Kyoto), Kimura Kenkadō (Osaka), and Hashimoto Sōkichi (Osaka). Genzui, after having successfully made good relations with Sugita Genpaku and Ohtsuki Gentaku, leading masters of the Edo school, played a role of an advocator for promoting "Rangaku" in Osaka and Kyoto. As a result, Kenkadō attained the publication of his book "Ikkaku Sankō," a monograph of the Western crude drug unicorn, with the help of Gentaku, who had translated a Dutch reference into Japanese for him. Ranshitsu and Sōkichi were taught the Dutch language by Gentaku; Sōkichi is known as the founder of "Rangaku" in Osaka.

Kyoto and the absence of leadership in Canada's capitals

Urquhart, I. [Alberta Univ., Dept. of Political Science, Edmonton, AB (Canada)

2003-01-01

A critique of Alberta's response to the Kyoto Protocol is presented. According to this author, Alberta's approach rests on a dubious foundation and is therefore 'wrongheaded'. Rather than being the economic disaster as characterized by the provincial government and the oil industry, the implementation costs of the Kyoto Protocol are likely to be much more incremental than Alberta's apocalyptic scenario suggests. With respect to cost, the author bolsters his case by citing the experience of British Petroleum Limited which has already reduced GHG emissions to 10 per cent below 1990 levels at 'no economic cost'. He argues that the 'made-in-Canada' environmental policy suggested by Alberta is no more likely to succeed than did the 'made-in-Canada' oil price policy in 1980. He makes a strong argument for the Kyoto Protocol as an opportunity to create federal-provincial strategies for all of Canada, and makes a strong case for institutional changes that would respect the legitimacy of federal and provincial interests in environmental policy issues. Given genuine effective leadership in Ottawa and in the provincial capitals, such changes could be an important step in the direction of increased reliance on one another as we try to secure a better future for all Canadians, and at the same time doing our bit in ensuring the survival of the planet.

This report sheds light on the economic issues surrounding climate change. The objective is to fuel a longer term reflexions. The greenhouse effect raises many questions dealing with economic policy. In particular what is the right agenda for action taking into account the low reversibility of the increasing concentration of greenhouse gases? What about the Kyoto protocol architecture? How to deal with countries that will not participate in the effort for controlling emissions, while enjoying the benefits of the preservation of the climate, a collective good? How to protect the competitiveness of countries that impose environmental constraints on their producers? This report is then discussed by P. Champsaur and A. Lipietz. (A.L.B.)

Development of the criticality capability for the SAM-CE Monte Carlo System

International Nuclear Information System (INIS)

Lichtenstein, H.; Troubetzkoy, E.; Steinberg, H.; Cohen, M.O.

1979-04-01

A criticality capabilty has been developed and implemented in the SAM-CE Monte Carlo system. The data processing component, SAM-X, preserves, to any required accuracy, the data quality inherent in the ENDF/B library. The generated data is Doppler-broadened and includes (where applicable) probability tables for the unresolved resonance range, and thermal-scattering law data. Curves of several total and partial cross sections are generated and displayed. The Monte Carlo component, SAM-F, includes several eigenvalue estimators and variance reduction schemes. Stratification was found to effect significant improvement in calculational efficiency, but the usefulness of importance sampling is marginal in criticality problems. The entire system has been installed at BNL, for the analysis of TRX benchmarks. The TRX-1 and TRX-2 cell calculations have been performed, with estimated eigenvalues of 1.1751 +- 0.0016 and 1.1605 +- .0015, respectively. These results are shown to be statistically consistent with other sources

Global property rights. The Kyoto protocol and the knowledge revolution

International Nuclear Information System (INIS)

Chichilnisky, G.

2006-01-01

This paper is about the origin of today's global environmental problems, and how to resolve them. At stake are catastrophic risks from global warming and damage to the world's biodiversity that ranks as the planet' sixth great extinction. The origin of today's global environmental problems is a historic difference in property rights regimes between industrial and developing countries, the North and the South. The solutions we suggest involve redefining property rights in the use of the global environment as well as in knowledge. We discuss the Kyoto Protocol's new systems of property rights on the use of the planet's atmosphere, and propose a parallel system of property rights on knowledge. Resources such as forests and oil and other mineral deposits are owned as private property in industrial countries but they are treated as common or government property in developing countries. Ill-defined protected property rights lead to the over-extraction of resources in the South, such as timber and oil. They are exported at low prices to the North that over-consumes them. The international market amplifies the tragedy of the commons, leading to inferior solutions for the world economy as a whole (Chichilnisky 1994). Updating property rights on resources in developing countries would face formidable opposition. The lack of property rights in inputs to production, such as timber and oil, could be compensated by assigning property rights on by-products of outputs. The 1997 Kyoto Protocol provides an example as it limits the countries' rights to emit carbon, a by-product of burning fossil fuels. Our suggestions for trading emissions rights (Chichilnisky 1995, 96) was adopted in the Kyoto Protocol, yet the atmosphere's carbon concentration is a global public good, which makes trading tricky. Trading rights to forests' carbon sequestration services or to genetic blueprints would also be trading global public goods. Markets that trade public goods have been shown to require a

Canada's nuclear industry, greenhouse gas emissions, and the Kyoto Protocol

Pendergast, D.R.; Duffey, R.B.; Tregunno, D.

1998-01-01

The Kyoto Protocol of the United Nations Framework Convention on Climate change, dated December 10, 1997 committed Canada to reduce greenhouse gases to 6% below 1990 levels by 2008-2012. Other nations also committed to varying degrees of reduction. The Protocol includes provisions for credit to the 'developed' counties for initiatives which lead to greenhouse gas reduction in the 'developing' countries and for the sharing of credit between 'developed' countries for projects undertaken jointly. The rules and details for implementation of these guidelines remain to be negotiated. We begin our study by establishing the magnitude of greenhouse gas emissions already avoided by the nuclear industry in Canada since the inception of commercial power plants in 1971. We then review projections of energy use in Canada and anticipated increase in electricity use up to the year 2020. These studies have anticipated no (or have 'not permitted') further development of nuclear electricity production in spite of the clear benefit with respect to greenhouse gas emission. The studies also predict a relatively small growth of electricity use. In fact the projections indicate a reversal of a trend toward increased per capita electricity use which is contrary to observations of electricity usage in national economies as they develop. We then provide estimates of the magnitude of greenhouse gas reduction which would result from replacing the projected increase in fossil fuel electricity by nuclear generation through the building of more plants and/or making better use of existing installations. This is followed by an estimate of additional nuclear capacity needed to avoid CO 2 emissions while providing the electricity needed should per capita usage remain constant. Canada's greenhouse gas reduction goal is a small fraction of international commitments. The Kyoto agreement's 'flexibility mechanism' provisions provide some expectation that Canada could obtain some credit for greenhouse gas

DnaSAM: Software to perform neutrality testing for large datasets with complex null models.

Patterns of DNA sequence polymorphisms can be used to understand the processes of demography and adaptation within natural populations. High-throughput generation of DNA sequence data has historically been the bottleneck with respect to data processing and experimental inference. Advances in marker technologies have largely solved this problem. Currently, the limiting step is computational, with most molecular population genetic software allowing a gene-by-gene analysis through a graphical user interface. An easy-to-use analysis program that allows both high-throughput processing of multiple sequence alignments along with the flexibility to simulate data under complex demographic scenarios is currently lacking. We introduce a new program, named DnaSAM, which allows high-throughput estimation of DNA sequence diversity and neutrality statistics from experimental data along with the ability to test those statistics via Monte Carlo coalescent simulations. These simulations are conducted using the ms program, which is able to incorporate several genetic parameters (e.g. recombination) and demographic scenarios (e.g. population bottlenecks). The output is a set of diversity and neutrality statistics with associated probability values under a user-specified null model that are stored in easy to manipulate text file. © 2009 Blackwell Publishing Ltd.

The self-assembled monolayers (SAMs) of 6-mercaptopurine (6MP) were formed at the roughened polycrystalline gold surfaces in acid and alkaline media. The time-dependent Raman mapping spectral analysis in conjunction with the quantum calculations for the vibrational modes using ab initio BLYP/6-31G method suggested that both of the resulted 6MP SAMs adopted the same adsorption mode through the S atom of pyrimidine moiety and the N7 atom of the imidazole moiety anchoring the gold surface in a vertical way. The in situ surface-enhanced Raman scattering spectroelectrochemical experiment was conducted to examine the stability of the SAMs at various bias potentials. It was found that the detaching process of the 6MP SAMs from the surface involved one electron reduction as the voltage was applied at ca. 0.7 V vs a standard calomel electrode.

Self-assembled monolayers (SAMs) of 6-mercaptopurine (6MP) on a silver electrode in acid and alkaline media were investigated by a combination protocol of the SERS technique with Raman mapping, and it was found that the adsorption mode of 6MP SAMs changed with the pH value of the environment. Quantum calculations for the vibrational mode were performed by the BLYP/6-31G method. 6MP was adsorbed on the silver electrode with a tilted orientation via S, N1, and N7 atoms in acid medium, while the SAMs adopted head-on adsorption modes with the S atom and the N1 atom anchoring the silver surface in alkaline medium. However, 6MP SAMs turned to the same upright orientation on the electrode through the S and N7 atoms when either acid or basic solution was removed. Stability of 6MP SAMs was observed by in situ SERS spectroelectrochemical measurements. The results reveal that the desorption potentials of 6MP SAMs formed under acid and alkaline conditions from the Ag electrode were at ca. -1.3 V and -1.6 V vs SCE, respectively.

UNFINISHED BUSINESS: The Economics of The Kyoto Protocol

The Kyoto Protocol to the Framework Convention on Climate Change (FCCC) was completed on the morning of December 11, 1997, following over two years of negotiations. The product of these deliberations is a complex and incomplete document knitting together the diversity of interests and perspectives represented by the more than 150 delegations. Because the document is complex, its implications are not immediately obvious. If it enters into force, the Kyoto Protocol will have far-reaching implications for all nations--both nations with obligations under the Protocol and those without obligations. National energy systems, and the world's energy system, could be forever changed. In this paper the authors develop an assessment of the energy and economic implications of achieving the goals of the Kyoto Protocol. They find that many of the details of the Protocol that remain to be worked out introduce critical uncertainties affecting the cost of compliance. There are also a variety of uncertainties that further complicate the analysis. These include future non-CO{sub 2} greenhouse gas emissions and the cost of their mitigation. Other uncertainties include the resolution of negotiations to establish rules for determining and allocating land-use emissions rights, mechanisms for Annex 1 trading, and participation by non-Annex 1 members in the Clean Development Mechanism. In addition, there are economic uncertainties, such as the behavior of Eastern Europe and the former Soviet Union in supplying emissions credits under Annex 1 trading. These uncertainties in turn could affect private sector investments in anticipation of the Protocol's entrance into force. The longer the nature of future obligations remains unclear, the less able decision makers will be to incorporate these rules into their investment decisions. They find that the cost of implementing the Protocol in the US can vary by more than an order of magnitude. The marginal cost could be as low as $26 per

The liquid-metal eutectic of gallium and indium (EGaIn) is a useful electrode for making soft electrical contacts to self-assembled monolayers (SAMs). This electrode has, however, one feature whose effect on charge transport has been incompletely understood: a thin (approximately 0.7 nm) film-consisting primarily of Ga(2)O(3)-that covers its surface when in contact with air. SAMs that rectify current have been measured using this electrode in Ag(TS)-SAM//Ga(2)O(3)/EGaIn (where Ag(TS) = template-stripped Ag surface) junctions. This paper organizes evidence, both published and unpublished, showing that the molecular structure of the SAM (specifically, the presence of an accessible molecular orbital asymmetrically located within the SAM), not the difference between the electrodes or the characteristics of the Ga(2)O(3) film, causes the observed rectification. By examining and ruling out potential mechanisms of rectification that rely either on the Ga(2)O(3) film or on the asymmetry of the electrodes, this paper demonstrates that the structure of the SAM dominates charge transport through Ag(TS)-SAM//Ga(2)O(3)/EGaIn junctions, and that the electrical characteristics of the Ga(2)O(3) film have a negligible effect on these measurements.

CE-SAM: a conversational interface for ISR mission support

There is considerable interest in natural language conversational interfaces. These allow for complex user interactions with systems, such as fulfilling information requirements in dynamic environments, without requiring extensive training or a technical background (e.g. in formal query languages or schemas). To leverage the advantages of conversational interactions we propose CE-SAM (Controlled English Sensor Assignment to Missions), a system that guides users through refining and satisfying their information needs in the context of Intelligence, Surveillance, and Reconnaissance (ISR) operations. The rapidly-increasing availability of sensing assets and other information sources poses substantial challenges to effective ISR resource management. In a coalition context, the problem is even more complex, because assets may be "owned" by different partners. We show how CE-SAM allows a user to refine and relate their ISR information needs to pre-existing concepts in an ISR knowledge base, via conversational interaction implemented on a tablet device. The knowledge base is represented using Controlled English (CE) - a form of controlled natural language that is both human-readable and machine processable (i.e. can be used to implement automated reasoning). Users interact with the CE-SAM conversational interface using natural language, which the system converts to CE for feeding-back to the user for confirmation (e.g. to reduce misunderstanding). We show that this process not only allows users to access the assets that can support their mission needs, but also assists them in extending the CE knowledge base with new concepts.

A set of thermal reactor benchmark calculations with SAM-CE which have been conducted at both MAGI and at BNL are described. Their purpose was both validation of the SAM-CE reactor eigenvalue capability developed by MAGI and a substantial contribution to the data testing of both ENDF/B-IV and ENDF/B-V libraries. This experience also resulted in increased calculational efficiency of the code and an example is given. The benchmark analysis included the TRX-1 infinite cell using both ENDF/B-IV and ENDF/B-V cross section sets and calculations using ENDF/B-IV of the TRX-1 full core and TRX-2 cell. BAPL-UO2-1 calculations were conducted for the cell using both ENDF/B-IV and ENDF/B-V and for the full core with ENDF/B-V

Kyoto discord: who bears the cost?

International Nuclear Information System (INIS)

Rubin, J.; Buchanan, P.

Since 1990, Canada's greenhouse gas emissions are up 20 per cent, meaning that Canada must reduce its emissions by 30 per cent between 2005 and 2010 to meet its commitment under the Kyoto Protocol. Ottawa has indicated that no one sector of the economy should bear the burden of this adjustment. The energy production sector accounts for almost 40 per cent of all greenhouse gas emissions. Our per capita emissions have risen 50 per cent faster than emissions in the United States. The authors compared our situation to that of Europe, where only a 5 per cent reduction is required, which can be explained by high taxes on energy users, and the closure of obsolete East German capacity which led to reductions of 100 million tonne in carbon dioxide emissions. Transportation is the second largest generator of greenhouse gas emissions with approximately 16 per cent. A quick overview of the energy sector was provided, touching on topics such as electric power generation, including coal-fired electrical production, and tar sands with its increasing importance to Canada's economy. Ottawa has released a plan in October 2002, where it indicates that industrial emitters will be required to cut 80 million tonnes through investments in more efficient technology. Tighter vehicle fuel and home insulation standards would account for 35 to 40 million tonnes of reduction, and 40 million tonnes would come from agriculture and forest management. It means there is a 60 million shortfall, and the tar sands industry will more than likely have to adjust, raising investor uncertainty over further development in that area. Climate change is unlikely to be modified by meeting the objectives of the Kyoto Protocol. The authors questioned whether the government shouldn't instead devote its resources to addressing the actual impact of climate change. 9 figs

Kyoto convention signed in December 1997 will, pending ratification, introduce legal obligations to countries of Annex I of the Convention to reduce CO 2 emission. Reductions will be obligatory for a number of small and medium European countries. Croatia will have to reduce its emission to 95% of the 1990 level. Possibility to meet this target without the use of new nuclear facility is doubtful. (author)

The rate of participation in breast cancer screening carried out by inspection and palpation associated with mammography in Kyoto Prefecture has been still low. In order to decrease the rate of breast cancer death, a high rate of screening participation must be achieved. We have organized the Kyoto Executive Committee of Pink Ribbon Activity aiming at the goal of achieving a 50% rate of participation in mammography screening by the end of 2010, and undertaken the following campaign activities: performing free screening, distribution and display of posters and leaflets about breast cancer screening, cooperation with various media to spread educational and informative messages, cooperation with a commercial institute in Kyoto City to distribute useful information, performing free breast cancer screening, and holding public lecture meetings, distribution of leaflets at student festivals at universities and colleges in Kyoto, and holding a ''Pink Ribbon symposium'' in a cosponsored company. All the above projects were performed successfully and many participants attended. We will continue these activities until the 50% participation rate is achieved. (author)

The new critical assembly type of nuclear reactor having three cores for the first time in the world was completed successfully at the Research Reactor Institute of Kyoto University in autumn of 1974. It is called KUCA (Kyoto University Critical Assembly). Safety of the critical assembly was considered sufficiently in consequence of discussions between the researchers of the institute and the design group of our company, and then many bright ideas were created through the discussions. This paper is described the new safety design of main equipments - oil pressure type center core drive mechanism, removable water overflow mechanism, core division mechanism, control rod drive mechansim, protection instrumentation system and interlock key system - for the critical assembly.

1998-01-01

The achievements of the Kyoto Protocol were highlighted. These achievements include recognition of the need for Annex 1 countries (developed countries) to define concrete emissions reduction targets to be accomplished by 2012; recognition of specific needs of developing countries; need for measures to anticipate, prevent or minimize the causes of climate change; recognition of the need that climate change policies and measures be cost effective; taking into account that economic development is essential for adopting measures to address climate change; recognition of the principle that corporations should promote a supportive and open international economic system leading to sustainable growth; and recognition that measures taken to combat climate change should not lead to unjustifiable discrimination in international trade. If the targets set at Kyoto are achieved, there will be an effective reduction in greenhouse gases of 5.2 per cent in relation to 1990 levels. The meeting in Buenos Aires should focus on strengthening the guidelines for actions agreed upon in Kyoto. Other major issues on the Buenos Aires Conference of Parties (COP 4) agenda should be to discuss ways and means to helping developing countries to deal with climate change issues within their own territories, agreement about definitive status of the Global Environmental Fund, arriving at a more precise definition of the Clean Development Mechanism, and first and foremost the development of credible national systems (i.e. Annex 1 countries) for the estimation of anthropogenic emission sources and removal by sinks of all greenhouse gases not controlled by the Montreal Protocol on the Ozone Layer, and shaping an adequate non-compliance system

Human fibroblasts were engineered to express the CRISPR-based synergistic activation mediator (SAM) complex: dCas9-VP64 and MS2-P65-HSF1. Two induced pluripotent stem cells (iPSCs) clones expressing SAM were established by transducing these fibroblasts with lentivirus expressing OCT4, SOX2, KLF4 and C-MYC. We have validated that the reprogramming cassette is silenced in the SAM iPSC clones. Expression of pluripotency genes (OCT4, SOX2, LIN28A, NANOG, GDF3, SSEA4, and TRA-1-60), differentiation potential to all three germ layers, and normal karyotypes are validated. These SAM-iPSCs provide a novel, useful tool to investigate genetic regulation of stem cell proliferation and differentiation through CRISPR-mediated activation of endogenous genes.

Approaching the national Kyoto Protocol (KP) targets involves a re-definition of the actual configuration of local energy systems. This study deals with a local scale application of the IEA-MARKAL models generator, in which the anthropogenic system of Basilicata Region (Southern Italy) is investigated to support the definition of coherent long- term strategies and sound climate protection policies. A scenario by scenario analysis points out the behaviour of the optimal mix of fuels and technologies in the presence of carbon dioxide emissions constraints. Trade off curves and reduced costs analyses outline the most effective actions for contributing to the national KP targets, with particular emphasis on the interventions in Civil (Residential, Commercial and Services) and waste management sectors.

Full Text Available American myth of material success had been orchestrated five basic beliefs that were reflected in Sam Walton’s biography, Sam Walton: Made in America-My Story. Those beliefs were: 1 Having a strong will to be successful man in America, Sam Walton was aware that the American democracy allowed its citizens to rise above any limitation in which they may have been born; 2 Then, he rose up from his limitation by hard work. His hard work successfully brought him to the riches and physical comforts; 3 He believed that those rewards came to those who were deserving of them (virtuous; 4 He also believed that those rewards came to those who had the drive and ambition to attain them. Therefore, he was optimistic to attain success in America; 5 Hard work to attain success made Sam Walton a lucky man who received good luck in his life. As a result, his dream of being a successful man in America came true. Keywords: the myth of material success, American dream, hard work

This paper focuses on the in-vessel phase of Severe Accident Management (SAM) strategy for a Korean 1000 MWe Pressurized Water Reactor (PWR) with reference to ROAAM+ framework approach. To apply ROAAM+, it is needed to identify epistemic and aleatory uncertainties. The selected scenario is a station blackout (SBO) and the corresponding SAM strategy is RCS depressurization followed by water injection into the reactor pressure vessel (RPV). The analysis considers the depressurization timing and the flow rate and timing of in-vessel injection for scenario variations. For the phenomenological uncertainties, the core melting and relocation process is considered to be the most important phenomenon in the in-vessel phase of SAM strategy. Accordingly, a sensitivity analysis is carried out to assess the impact of the cut-off porosity below which the flow area of a core node is zero (EPSCUT), and the critical temperature for cladding rupture (TCLMAX) on the core melting and relocation process. In this paper, the SAM strategy for maintaining the integrity of RPV is derived after quantification of the scenario and phenomenological uncertainties.

Enterovirus 71 (EV71) recruits various cellular factors to assist in the replication and translation of its genome. Identification of the host factors involved in the EV71 life cycle not only will enable a better understanding of the infection mechanism but also has the potential to be of use in the development of antiviral therapeutics. In this study, we demonstrated that the cellular factor 68-kDa Src-associated protein in mitosis (Sam68) acts as an internal ribosome entry site (IRES) trans-acting factor (ITAF) that binds specifically to the EV71 5' untranslated region (5'UTR). Interaction sites in both the viral IRES (stem-loops IV and V) and the heterogeneous nuclear ribonucleoprotein K homology (KH) domain of Sam68 protein were further mapped using an electrophoretic mobility shift assay (EMSA) and biotin RNA pulldown assay. More importantly, dual-luciferase (firefly) reporter analysis suggested that overexpression of Sam68 positively regulated IRES-dependent translation of virus proteins. In contrast, both IRES activity and viral protein translation significantly decreased in Sam68 knockdown cells compared with the negative-control cells treated with short hairpin RNA (shRNA). However, downregulation of Sam68 did not have a significant inhibitory effect on the accumulation of the EV71 genome. Moreover, Sam68 was redistributed from the nucleus to the cytoplasm and interacts with cellular factors, such as poly(rC)-binding protein 2 (PCBP2) and poly(A)-binding protein (PABP), during EV71 infection. The cytoplasmic relocalization of Sam68 in EV71-infected cells may be involved in the enhancement of EV71 IRES-mediated translation. Since Sam68 is known to be a RNA-binding protein, these results provide direct evidence that Sam68 is a novel ITAF that interacts with EV71 IRES and positively regulates viral protein translation. The nuclear protein Sam68 is found as an additional new host factor that interacts with the EV71 IRES during infection and could potentially

Post-translational modification of ribosomally synthesized peptides by a radical SAM epimerase in Bacillus subtilis

2017-07-01

Ribosomally synthesized peptides are built out of L-amino acids, whereas D-amino acids are generally the hallmark of non-ribosomal synthetic processes. Here we show that the model bacterium Bacillus subtilis is able to produce a novel type of ribosomally synthesized and post-translationally modified peptide that contains D-amino acids, and which we propose to call epipeptides. We demonstrate that a two [4Fe-4S]-cluster radical S-adenosyl-L-methionine (SAM) enzyme converts L-amino acids into their D-counterparts by catalysing Cα-hydrogen-atom abstraction and using a critical cysteine residue as the hydrogen-atom donor. Unexpectedly, these D-amino acid residues proved to be essential for the activity of a peptide that induces the expression of LiaRS, a major component of the bacterial cell envelope stress-response system. Present in B. subtilis and in several members of the human microbiome, these epipeptides and radical SAM epimerases broaden the landscape of peptidyl structures accessible to living organisms.

SAM is a suite of instruments that will be onboard the Mars Science Laboratory (MSL) rover. The SAM team consist of scientists and engineers at GSFC, U. Paris/CNRS, JPL, and Honeybee Robotics, along with many additional external partners. SAM's five science goals will address three of the most fundamental questions about the ability of Mars to support life -past, present, and future. Question 1: What does the inventory of carbon compounds near the surface of Mars tell us about its potential habitability? 1.Goal 1: Survey carbon compound sources and evaluate their possible mechanism of formation and destruction. 2.Goal 2: Search for organic compounds of biotic and prebiotic importance expecially methane. Question 2: What are the chemical and isotopic states of the lighter elements in the solids and atmosphere of Mars and what do they tell us about its potential habitability? 1.Goal 3: Reveal the chemical and isotopic state of elements (i.e., N, H, O, S and others) that are important for life as we know it. 2.Goal 4: Evaluate the habitability of Mars by studying its atmospheric chemistry and the composition of trace species that are evidence of interactions between the atmosphere and soil. Question 3: Were past habitability conditions different from today's? 1.Goal 5: Understand atmospheric and climatic evolution through measurements of noble gas and light element isotopes.

A low-carbon scenario creation method for a local-scale economy and its application in Kyoto city

International Nuclear Information System (INIS)

Gomi, Kei; Shimada, Kouji; Matsuoka, Yuzuru

2010-01-01

On May 2008, Kyoto city government set up a low-carbon target of a 50% GHG reduction by 2030 compared to the 1990 level. To contribute to these discussions, we developed a local (city-scale) low-carbon scenario creation method. An estimation model was developed to show a quantitative and consistent future snapshot. The model can explicitly treat the uncertainty of future socio-economic situations, which originate from the openness of local economy. The method was applied to Kyoto city, and countermeasures to achieve the low-carbon target were identified. Without countermeasures, emissions would increase 12% from 2000. Among the measures, the reduction potential of energy efficiency improvements to residential and commercial sectors was found to be relatively large (15% and 18% of total reductions, respectively). The reduction potential of the passenger transport sector, in which the city government's policy is especially important, was 17% of the total amount. A sensitivity analysis showed that a 10% increase in exports leads to an 8.5% increase in CO 2 emissions, and a 20% increase in the share of the commuters from outside the city leads to a 3.5% decrease of CO 2 emissions because of the smaller number of residents in the city.

Abstract Background CASKIN2 is a homolog of CASKIN1, a scaffolding protein that participates in a signaling network with CASK (calcium/calmodulin-dependent serine kinase). Despite a high level of homology between CASKIN2 and CASKIN1, CASKIN2 cannot bind CASK due to the absence of a CASK Interaction Domain and consequently, may have evolved undiscovered structural and functional distinctions. Results We demonstrate that the crystal structure of the Sterile Alpha Motif (SAM) domain tandem (SAM1-SAM2) oligomer from CASKIN2 is different than CASKIN1, with the minimal repeating unit being a dimer, rather than a monomer. Analytical ultracentrifugation sedimentation velocity methods revealed differences in monomer/dimer equilibria across a range of concentrations and ionic strengths for the wild type CASKIN2 SAM tandem and a structure-directed double mutant that could not oligomerize. Further distinguishing CASKIN2 from CASKIN1, EGFP-tagged SAM tandem proteins expressed in Neuro2a cells produced punctae that were distinct both in shape and size. Conclusions This study illustrates a new way in which neuronal SAM domains can assemble into large macromolecular assemblies that might concentrate and amplify synaptic responses.

Reference Manual for the System Advisor Model's Wind Power Performance Model

Energy Technology Data Exchange (ETDEWEB)

Freeman, J.; Jorgenson, J.; Gilman, P.; Ferguson, T.

2014-08-01

This manual describes the National Renewable Energy Laboratory's System Advisor Model (SAM) wind power performance model. The model calculates the hourly electrical output of a single wind turbine or of a wind farm. The wind power performance model requires information about the wind resource, wind turbine specifications, wind farm layout (if applicable), and costs. In SAM, the performance model can be coupled to one of the financial models to calculate economic metrics for residential, commercial, or utility-scale wind projects. This manual describes the algorithms used by the wind power performance model, which is available in the SAM user interface and as part of the SAM Simulation Core (SSC) library, and is intended to supplement the user documentation that comes with the software.

'Charles River Associates analysis : impact of the world implementing the Kyoto Protocol : analysis of the impact on the Canadian upstream oil and gas industry of the global implementation of the Kyoto Protocol

International Nuclear Information System (INIS)

1999-09-01

A study was conducted to estimate the impacts on the Canadian oil and gas industry from the changes in demand for oil and natural gas fuels caused by implementation of the Kyoto Protocol throughout the Canadian economy. The multi-sector, multi-region trade (MS-MRT) model was used in the study. The MS-MRT was designed to study the effects of carbon restrictions on industrial output, trade and economic welfare in different regions of the world. An overview of the model was presented. The regions in the MS-MRT model are divided as follows: Canada; United States; European Union; Other OECD; Eastern Europe and Former Soviet Union; Non-OECD Asia; Mexico and OPEC; and all other countries. This paper also described how production, consumption and trade are modelled. The cases under which the impacts on the Canadian oil and gas sectors are modelled were also presented. refs., tabs., figs

Improving and minimizing challenging behaviors seen in psychiatric conditions, including behavioral and psychological symptoms of dementia are important in the care of people with these conditions. Yet there is a lack of systematic evaluation of these as a part of routine clinical care. The Neuropsychiatric Inventory is a validated and reliable tool for rating the severity and disruptiveness of challenging behaviors. We report on the evaluation of a Web-based symptom assessment manager (SAM), designed to address the limitation of previous tools using some of the Neuropsychiatric Inventory functions, to monitor behaviors by staff caring for people with dementia and other psychiatric conditions in inpatient and residential care settings. The SAM was piloted in an 8-bed inpatient neuropsychiatry unit over 5 months. Eleven nurses and 4 clinicians were trained in usage of SAM. Primary outcomes were usage of SAM and perceived usability, utility, and acceptance of SAM. Secondary outcomes were the frequencies of documented behavior. Usage data were analyzed using chi-square and logistic regression analyses. The SAM was used for all admitted patients regardless of diagnosis, with a usage rate of 64% for nurses regularly employed in the unit. Staff provided positive feedback regarding the utility of SAM. The SAM appeared to offer individualized behavior assessment by providing a quick, structured, and standardized platform for assessing behavior in a real-world setting. Further research would involve trialing SAM with more staff in alternative settings such as in home or residential care settings. Copyright © 2017 John Wiley & Sons, Ltd.

Implementing the Kyoto Protocol. The role of environmental agreements

Energy Technology Data Exchange (ETDEWEB)

Torvanger, Asbjoern; Skodvin, Tora

1999-09-01

This report examines under what circumstances voluntary agreements to curb greenhouse gas emissions could be an attractive policy option from the government`s perspective. The report begins by defining the term Environmental Agreement (EA) and then explores EAs in three steps: (1) Advantages and disadvantages of EAs compared to other policy tools (direct regulation, taxes and tradable permits), based on theoretical studies and experience from practical use, (2) The potential of EAs as an international policy tool, either in a bilateral or regional setting, (3) The attractiveness of EAs to implement the Kyoto Protocol, and the relation to joint implementation and international emissions trading. The main conclusions are: (1) Experience from OECD countries suggests that EAs are most attractive as a supplement to traditional command and control, or to market-based policy tools. (2) Skillful design of EAs can improve their efficiency. (3) Bilateral EAs is an interesting policy option to regulate pollution from other countries. (4) Regional EAs are rare but could have important advantages. (5) EAs can play a role in a soft transition stage from traditional command and control to domestic emission trading, and further on to a Kyoto Protocol regime of emission trading and joint implementation. 52 refs., 2 figs., 2 tabs.

Toposelective electrochemical desorption of thiol SAMs from neighboring polycrystalline gold surfaces.

Science.gov (United States)

Tencer, Michal; Berini, Pierre

2008-11-04

We describe a method for the selective desorption of thiol self-assembled monolayers from gold surfaces having micrometer-scale separations on a substrate. In an electrolyte solution, the electrical resistance between the adjacent areas can be much lower than the resistance between a surface and the counter electrode. Also, both reductive and oxidative thiol desorption may occur. Therefore, the potentials of the surfaces must be independently controlled with a multichannel potentiostat and operating windows for a given thiol/electrolyte system must be established. In this study operating windows were established for 1-dodecanethiol-based SAMs in phosphate buffer, phosphate-buffered saline, and sodium hydroxide solution, and selective SAM removal was successfully performed in a four-electrode configuration.

Fulfilling the Kyoto protocol in Spain: A matter of economic crisis or environmental policies?

2012-01-01

In 2008, Spain exceeded by 20.9% the CO 2 emissions allowed by the Kyoto Protocol for 2012. The financial and economic crisis has transformed these figures: as production fell so did energy demand and with it CO 2 emissions. Will the Spanish economic crisis allow Spain to fulfill its commitments? With this in mind, we have developed an extended input–output model able to forecast energy demand and compute CO 2 emissions linked to the consumption of energy goods: petroleum products, gas and coal. The results show that the crisis, and in particularly, the stagnation of the construction industry, is only one of the pillars which help to contain these emissions at −6.81%. The possibility of incorporating environmental policies, new technologies and increases in the price of crude oil in these simulations, means an even greater reduction of emissions than the impact of the crisis (−9.76%). The final result of our most pessimistic/realistic scenario is that, in 2012, Spain will exceed its CO 2 emissions, linked to the combustion of energy goods, by only 0.9%. - Highlights: ► We use an extended input–output model to forecast the evolution of CO 2 emissions. We evaluate the economic crisis impact on emissions figures (2008–2012). ► The environmental policies are introduced by considering structural trends. ► In our reference scenario, Spain exceeds Kyoto commitments only by 0.9% in 2012. ► The 16.6% emissions reduction is explained by trends (−9.8%) and crisis (−6,8%).

A not well managed drastic reduction of greenhouse emissions might result in significant decrease of living standards, but without such reduction efforts, climate change might have five to twenty times higher costs. Thus, while indicating estimated consequences or evolutions of greenhouse emissions and temperature, the author stresses the need of emission reduction. She discusses the role of economic instruments which can be used in policies aimed at the struggle against climate change. She recalls the emission reduction commitments specified in the Kyoto protocol, discusses the present status, operation and results of the international emission trading scheme, the lessons learned after the first years of operation, comments the involvement of emerging countries in relationship with another mechanism defined in the protocol: the Clean Development Mechanism

No kudos for Kyoto from Imperial Oil : one company kicks at CO2 compliance, while others assume Ottawa's posturing

International Nuclear Information System (INIS)

Hope, P.

1998-01-01

Imperial Oil Ltd.'s criticisms over the high cost of complying with the carbon dioxide reduction targets set at Kyoto were discussed. Imperial Oil's document entitled 'The high cost of Kyoto' cites various independent economic-impact studies which show that Canada's commitment to lower greenhouse gas emissions to six per cent below 1990 levels by 2010 would jeopardize Canada's current prosperity and would drop the gross domestic product 3 per cent below projected growth. Several other major oil companies including Suncor share the opinion that the science on global warming is uncertain and that more research and greater public involvement is needed in the debate over the Kyoto Protocol. The oil companies are also of one mind about the need for third world countries doing their share of emission reduction. They go as far as to say that third world countries such as China and Brazil should be forced to join Canada in restricting emissions. The major oil companies operating in Canada hope that the government will consider oil industry concerns before the Kyoto Protocol is ratified. 1 fig

This document provides data and operations needed to evaluate the impacts of the nuclear phaseout on the respect of the Kyoto protocol. The data are based on the belgium electricity production. The author concludes that the nuclear power plants shutdown will lead to a non respect of the kyoto protocol in unacceptable limits. To respect the protocol, he presents two possibilities: the today nuclear park and the use of 1600 wind turbines of 2 MW, or the improvement of the energy efficiency of the thermal power plants.

Red auroras were observed in Japan during an extreme magnetic storm that occurred on 17 September 1770. We show new evidence that the red aurora extended toward the zenith of Kyoto around midnight. The basic appearance of the historical painting of the red aurora is geometrically reproduced based on the inclination of the local magnetic field and a detailed description in a newly discovered diary. The presence of the inclined zenith aurora over Kyoto suggests that the intensity of the September 1770 magnetic storm is comparable to, or slightly larger than that of the September 1859 Carrington storm.

Kyoto or non-Kyoto - people or politics: results of recent public opinion surveys on energy and climate change

2007-01-01

Full text: We present the results of a survey of an Australian public opinion survey in the area of climate change and energy technologies and compare the results with similar studies conducted in the other major non-Kyoto-adherent party, the United States, as well as to Kyoto-adherent countries including the UK, Japan, Sweden and Spain. We explore some of the differences and similarities in attitudes and understandings. In our survey, Australians place environment, health care and petrol prices as the most important issues facing their country, while in America it is terrorism, health care and the economy and in the UK it is asylum seekers, crime and health care. In many other areas, the differences are considerably smaller and there are some remarkable similarities. Whereas climate change is increasingly cited as the leading environmental issue in most countries surveyed, in Australia, climate change is second to water availability as the top environmental concern. The study examines where climate change and energy technologies fit within these broader national and environmental priorities and identifies the general public's preferred solutions. We find clear support in Australia and the other countries surveyed for renewable energy technologies, particularly solar energy and to a lesser extent wind and biomass energy. We also find considerable disagreement in all countries regarding the future of nuclear power as well as with regard to carbon dioxide capture and storage technologies (albeit the latter with much larger uncertainty). The paper also explores the current knowledge levels of the general public in a number of countries about carbon dioxide emissions and how much as individuals, they are prepared to pay to mitigate greenhouse gas emissions. We find that, in general, at a more detailed level in terms of both attitudes and understandings of energy and climate issues there is considerable agreement across disparate countries Gudged on their national

Cooperation mechanisms of the EU renewable energy directive and flexible mechanisms of the Kyoto Protocol: comparison and lessons learnt. Working paper

2013-07-15

This working paper discusses similarities and differences between the cooperation mechanisms of the EU renewable energy directive (RES directive) and the flexible mechanisms of the Kyoto Protocol. The cooperation mechanisms allow the (virtual) trade of renewable energy and were introduced with the RES directive to provide Member States (MS) with greater flexibility to achieve their national targets for renewable energy sources (RES). A similar kind of flexibility is known from the flexible mechanisms of the Kyoto Protocol which aim at the cost efficient achievement of emission reduction targets. Lessons learned from the Kyoto mechanisms may allow conclusions to be drawn on the design and implementation of the renewable energy cooperation mechanisms. This paper first gives an overview of the cooperation mechanisms regarding their potential, advantages and disadvantages, barriers and preconditions. This is followed by a brief explanation of and a systematic comparison with the flexible mechanisms of the Kyoto Protocol – Joint Implementation (JI); Clean Development Mechanism (CDM); and International Emissions Trading (IET). A gamut of factors influenced the success of the Kyoto mechanisms in general and in specific national contexts. Therefore, it is not possible to directly transfer past experiences with the Kyoto mechanisms to the capability of specific nations to make use of the renewable energy cooperation mechanisms. A comparison of specific features, such as the mechanism type (transfer, project-based, support scheme), price building and specific barriers can, however, help anticipate the possible dynamics and challenges of the cooperation mechanisms. Experiences with the Kyoto mechanisms show that predictions based on supply-demand analysis were valid only to a limited extent and that specific factors such as institutional capacity constraints or legal uncertainties delayed or prevented the use of the mechanisms in some cases. Similarly, for the cooperation

This report sheds light on the economic issues surrounding climate change. The objective is to fuel a longer term reflexions. The greenhouse effect raises many questions dealing with economic policy. In particular what is the right agenda for action taking into account the low reversibility of the increasing concentration of greenhouse gases? What about the Kyoto protocol architecture? How to deal with countries that will not participate in the effort for controlling emissions, while enjoying the benefits of the preservation of the climate, a collective good? How to protect the competitiveness of countries that impose environmental constraints on their producers? This report is then discussed by P. Champsaur and A. Lipietz. (A.L.B.)

Is the Kyoto Protocol an adequate environmental agreement to resolve the climate change problem?

International Nuclear Information System (INIS)

Arcas, R.L.

2001-01-01

The lack of understanding on how to handle the issue of global warming, which is embodied by the Kyoto Protocol, among the various nations of the world reached a point where environmental policy-makers saw a number of possible scenarios to global warming before the last meeting on Climate Change in July 2001 in Bonn: Amendments to the Kyoto Protocol, by changing the current targets and timetable into a long-term view of the global warming issue. The U.S. does not agree with the Kyoto Protocol Therefore, it will not do anything about it in terms of its ratification. A middle ground between the two previous options. The idea is the creation of a new mechanism where nations meet in international environmental for a voluntarily exchange of views with no legal commitments. In order to move forward, we should stop thinking of the global warming issue only in a cost-benefit analysis and instead take more into account public health and safety requirements. Since the U.S. and EU representatives may well find themselves deadlocked again when they meet at the end of October 2001 in Morocco for the next climate change convention, the author would like to make some recommendations at the end of this article.

Written materials are frequently used to provide education to stroke patients and their carers. However, poor quality materials are a barrier to effective information provision. A quick and reliable method of evaluating material quality is needed. This study evaluated the interrater reliability of the Suitability Assessment of Materials (SAM) checklist in a sample of written stroke education materials. Two independent raters evaluated the materials (n = 25) using the SAM, and ratings were analyzed to reveal total percentage agreements and weighted kappa values for individual items and overall SAM rating. The majority of the individual SAM items had high interrater reliability, with 17 of the 22 items achieving substantial, almost perfect, or perfect weighted kappa value scores. The overall SAM rating achieved a weighted kappa value of 0.60, with a percentage total agreement of 96%. Health care professionals should evaluate the content and design characteristics of written education materials before using them with patients. A tool such as the SAM checklist can be used; however, raters should exercise caution when interpreting results from items with more subjective scoring criteria. Refinements to the scoring criteria for these items are recommended. The value of the SAM is that it can be used to identify specific elements that should be modified before education materials are provided to patients.

The application of a recently developed method for the deposition of Pd and Pt on top of a SAM, has been successfully extended to Rh, thus proving the versatility of the new concept. Experimental evidence from cyclic voltammetry, in situ STM and ex situ X-ray photoemission spectroscopy is presented for the deposition of monoatomic high rhodium islands onto a 4-mercaptopyridine self-assembled monolayer on a Au(1 1 1) electrode. By repetitive complexation of the Rh ions to the ring-nitrogen and reduction in a Rh-ion free solution, an almost completely covered SAM is obtained. The consequences of making contacts for molecular electronics are briefly discussed.

One of the most serious and current environmental global problems is the Climate Change generated by the increasing of Green House gas (GHG) level. Romania has signed the United Nation Framework Convention on Climate Change and is the first country listed in Convention Annex I which ratified Kyoto Protocol. Romania committed itself to lower the level of GHG emissions with 8% as compared with the GHG emissions level in 1989, what is similar to the commitment of EU countries. In order to satisfy the requirements of accession to the European Union, Romania has also developed several national strategies to promote sustainable development. Hidroelectrica's Environmental Policy includes international partnership to finance the hydropower projects under Kyoto Protocol of United Nation Framework Convention on Climate Change. Hidroelectrica has submitted Joint Implementation projects to the PCF program of World Bank and ERUPT programs of Dutch Government. The paper reflects Hidroelectrica's experience in that field: the actions necessary to initiate and promote such projects, the steps recommended in developing their implementation, difficulties and barriers, results obtained, learned lessons.

The System Advisor Model (SAM) is a free software tool that performs detailed analysis of both system performance and system financing for a variety of renewable energy technologies. This report provides detailed validation of the SAM flat plate photovoltaic performance model by comparing SAM-modeled PV system generation data to actual measured production data for nine PV systems ranging from 75 kW to greater than 25 MW in size. The results show strong agreement between SAM predictions and field data, with annualized prediction error below 3% for all fixed tilt cases and below 8% for all one axis tracked cases. The analysis concludes that snow cover and system outages are the primary sources of disagreement, and other deviations resulting from seasonal biases in the irradiation models and one axis tracking issues are discussed in detail.

Head-to-tail polymers of sterile alpha motifs (SAM) can scaffold large macromolecular complexes. Several SAM-domain proteins that bind each other are mutated in patients with cystic kidneys or laterality defects, including the Ankyrin (ANK) and SAM domain-containing proteins ANKS6 and ANKS3, and the RNA-binding protein Bicc1. To address how their interactions are regulated, we first determined a high-resolution crystal structure of a Bicc1-SAM polymer, revealing a canonical SAM polymer with a high degree of flexibility in the subunit interface orientations. We further mapped interactions between full-length and distinct domains of Bicc1, ANKS3, and ANKS6. Neither ANKS3 nor ANKS6 alone formed macroscopic homopolymers in vivo. However, ANKS3 recruited ANKS6 to Bicc1, and the three proteins together cooperatively generated giant macromolecular complexes. Thus, the giant assemblies are shaped by SAM domains, their flanking sequences, and SAM-independent protein-protein and protein-mRNA interactions. Copyright © 2017 Elsevier Ltd. All rights reserved.

The surface Fermi level of semi-insulating and n{sup +}-type GaAs(0 0 1) was determined before and after passivation with n-alkanethiol self-assembled monolayers (SAMs) by X-ray photoelectron spectroscopy. Fermi level positioning was achieved using Au calibration pads integrated directly onto the GaAs surface, prior to SAM deposition, in order to provide a surface equipotential binding energy reference. Fermi level pinning within 50 meV and surface barrier characteristics according to the Advanced Unified Defect Model were observed. Our results demonstrate the effectiveness of the Au integration technique for the determination of band-edge referenced Fermi level positions and are relevant to an understanding of emerging technologies based on the molecular-semiconductor junction.

The kyoto university reactor physics experiments on the university critical assembly is used to benchmark validate the NCNSRC calculations methodology. This methodology has two lines, diffusion and Monte Carlo. The diffusion line includes the codes WIMSD4 for cell calculations and the two dimensional diffusion code DIXY2 for core calculations. The transport line uses the MULTIKENO-Code vax Version. Analysis is performed for the criticality, and the temperature coefficients of reactivity (TCR) for the light water moderated and reflected cores, of the different cores utilized in the experiments. The results of both Eigen value and TCR approximately reproduced the experimental and theoretical Kyoto results. However, some conclusions are drawn about the adequacy of the standard wimsd4 library. This paper is an extension of the NCNSRC efforts to assess and validate computer tools and methods for both Et-R R-1 and Et-MMpr-2 research reactors. 7 figs., 1 tab

This paper presents the results of two computational large scale studies using highly realistic exposure scenarios, MRI based human head and hand models, and two mobile phone models. The objectives are (i) to study the relevance of age when people are exposed to RF by comparing adult and child heads and (ii) to analyze and discuss the conservativeness of the SAM phantom for all age groups. Representative use conditions were simulated using detailed CAD models of two mobile phones operating between 900 MHz and 1950 MHz including configurations with the hand holding the phone, which were not considered in most previous studies. The peak spatial-average specific absorption rate (psSAR) in the head and the pinna tissues is assessed using anatomically accurate head and hand models. The first of the two mentioned studies involved nine head-, four hand- and two phone-models, the second study included six head-, four hand- and three simplified phone-models (over 400 configurations in total). In addition, both studies also evaluated the exposure using the SAM phantom. Results show no systematic differences between psSAR induced in the adult and child heads. The exposure level and its variation for different age groups may be different for particular phones, but no correlation between psSAR and model age was found. The psSAR from all exposure conditions was compared to the corresponding configurations using SAM, which was found to be conservative in the large majority of cases.

The aim of this study is to discuss the long term analysis of post-Kyoto commitments, with the modelling tool ETSAP-TIAM-FR. Through the specification of CO2 mitigation targets scenarios covering the period 2000-2050, this analysis focuses on the effects of these carbon constraints on several indicators such as global and regional CO2 emissions, the cost of the climate policy, carbon marginal costs, the primary energy consumption and the energy mix. This paper compares global efforts of CO2 mitigation with the cost of carbon and finally discusses the development of CCS technologies.

The characterisation of the chemical and mineralogical composition of regolith samples collected with the Curiosity rover is a primary objective of the SAM experiment. These data should provide essential clues on the past habitability of Gale crater. Amongst the SAM suite of instruments [1], SAM-GC (Gas Chromatograph) is devoted to identify and quantify volatiles evolved from the thermal (heating up to about 900°C)/chemical (derivatization procedure) treatment of any soil sample collected by the Curiosity rover. With the aim to search for potential organic molecules outgassed from the samples, a SAM-GC analytical channel composed of thermal-desorption injector and a MXT-CLP chromatographic column was chosen to achieve all the measurements done up today, as it was designed for the separation of a wide range of volatile organic molecules. Three solid samples have been analyzed with GCMS, one sand sample collected at the Rocknest site, and two rock samples (John Klein and Cumberland respectively) collected at the Yellowknife Bay site using the Curiosity driller. All the measurements were successful and they produced complex chromatograms with both detectors used for SAM GC, i.e. a thermal conductivity detector and the SAM quandrupole mass spectrometer. Their interpretation already revealed the presence of an oxychlorine phase present in the sample which is at the origin of chlorohydrocarbons clearly identified [2] but this represents only a fraction of the GCMS signal recorded [3,4]. This work presents a systematic comparison of the GCMS measurements done for the different samples collected, supported by reference data obtained in laboratory with different spare models of the gas chromatograph, with the aim to bring new elements of interpretation of the SAM measurements.

Ethylene plays critical roles in plant development and biotic stress response, but the mechanism of ethylene in host antiviral response remains unclear. Here, we report that Rice dwarf virus (RDV) triggers ethylene production by stimulating the activity of S-adenosyl-L-methionine synthetase (SAMS), a key component of the ethylene synthesis pathway, resulting in elevated susceptibility to RDV. RDV-encoded Pns11 protein specifically interacted with OsSAMS1 to enhance its enzymatic activity, leading to higher ethylene levels in both RDV-infected and Pns11-overexpressing rice. Consistent with a counter-defense role for ethylene, Pns11-overexpressing rice, as well as those overexpressing OsSAMS1 , were substantially more susceptible to RDV infection, and a similar effect was observed in rice plants treated with an ethylene precursor. Conversely, OsSAMS1- knockout mutants, as well as an osein2 mutant defective in ethylene signaling, resisted RDV infection more robustly. Our findings uncover a novel mechanism which RDV manipulates ethylene biosynthesis in the host plants to achieve efficient infection.

Jelavic, V.; Sestic, M.; Juric, Z.; Stanic, Z.

1998-01-01

The Kyoto Protocol obliges the Republic of Croatia to reduce greenhouse gas emissions by 5 percent till the year 2010, taking a base year from the period between 1985 and 1990. Thermal power plants of Hrvatska Elektroprivreda (HEP) represent significant source of the most important greenhouse gas - CO 2 - and consequently HEP is expected to make a significant contribution to the national activities aiming to meet the Kyoto Protocol requirements. This issue is of particular importance, as Croatia has not submitted its base year to the Conference of the Parties in form of The National Communication on Climate Change, which is one of the requirements of UN Climate Change Convention and the Kyoto Protocol. Related to this, it is interesting to include emissions from the thermal power plants located in Bosnia and Herzegovina and Serbia (650 MWe) that had supplied electricity to the Croatian power supply system in the base year period and on which HEP claims legal ownership. This article presents HEP greenhouse gas emissions from the period of 1985 to 1990, as well as its contribution in total greenhouse gas emissions of Croatia. Furthermore, future HEP greenhouse gas emissions, according to its business development scenario till the year 2010, will be estimated. (author)

Development of Taiwanese government’s climate policy after the Kyoto protocol: Applying policy network theory as an analytical framework

International Nuclear Information System (INIS)

Shyu, Chian-Woei

2014-01-01

Given its limited involvement in and recognition by international organizations, Taiwan is not presently a signatory to the United Nations Framework Convention on Climate Change (UNFCCC) or the Kyoto Protocol. The objective of this study is to analyze how and the extent to which changes in an exogenous factor, namely the Kyoto Protocol and Post-Kyoto climate negotiations, affect and ultimately lead to the formulation of and changes in the Taiwanese government's climate policy. This study applies policy network theory to examine the development of and changes in the Taiwanese government's climate policy. The results demonstrate that international climate agreements and negotiations play a key role in the development of, changes to, and transformation of Taiwan's climate policy. Scarce evidence was found in this study to demonstrate that domestic or internal factors affect climate change policy. Despite its lack of participation in the UNFCCC and the Kyoto Protocol, Taiwan has adopted national climate change strategies, action plans, and programs to reduce greenhouse gas emissions. However, these climate policies and measures are fairly passive and aim to only conform to the minimal requirements for developing countries under international climate agreements and negotiations. This process results in inconsistent and variable climate policies, targets, and regulations. - Highlights: • Taiwan is not a signatory to the UNFCCC or its Kyoto Protocol. • International climate agreements strongly affected Taiwan's climate policy. • Little evidence was found that domestic factors affect Taiwan's climate policy. • New climate policies, regulations, and laws are formulated and implemented. • Climate policies, targets, and regulations change frequently and are inconsistent

Observations of microtremors were carried out to estimate the S-wave velocity structure by using arrays of seismographs around the Kyoto Research Park. The observation points were so arranged that equilateral triangle arrays may be formed with maximum radii at 0.2 km, 0.4 km and 0.8 km respectively with the premises of the Kyoto Research Park as the center. The seismographs have used seven vertical movement components (PELS), and were adjusted to a period of eight seconds. In addition, high-cut filters of 4 Hz were used because the observation areas are located in urban areas with heavy traffic. The analysis has used the spatial self-correlation method as a means to estimate phase velocity of surface waves contained in microtremors. As a result, phase velocity estimation has become possible for frequencies from about 0.4 Hz to 2 Hz, whereas the S-wave velocity structure was estimated to a depth of down to about 900 m by using as reference the result of the reflection method exploration having been carried out in the present areas. In addition, it was suggested that microtremors with frequencies higher than 1 Hz are in unsteady state in terms of time or space. 4 refs., 7 figs., 1 tab.

Endogenous induced technical change and the costs of Kyoto

International Nuclear Information System (INIS)

Buonanno, Paolo; Carraro, Carlo; Galeotti, M.

2001-09-01

Many predictions and conclusions in the climate change literature have been made and drawn on the basis of theoretical analyses and quantitative models that are either static or that allow for simple forms of changes in technology, often along exogenously given time paths. It is therefore not clear a priori whether those conclusions and policy recipes still hold in the more realistic case of endogenously evolving technologies. In this paper, a quantitative tool with the features of an endogenous growth model is presented, which also accounts for the possibility that technical change can be induced by environmental policy measures. Both the output production technology and the emission-output ratio depend upon the stock of knowledge, which accumulates through R and D activities. R and D is thus an additional policy variable that comes into play along with pollution abatement and capital investment. Two versions of this climate model are studied, one with endogenous technical change but exogenous environmental technical change (i.e. no induced technical change) and the other with both endogenous and induced technical change. Hence, in both models technical change evolves endogenously as far as the production technology is concerned, but endogenous environmental (or induced) technical change is only accounted for in the second version. Finally, a third version of the model also captures technological spillover effects. As an application, the three versions of the model are simulated allowing for trade of pollution permits as specified in the Kyoto Protocol and assessing the implications in terms of cost efficiency, economic growth and R and D efforts of the three different specifications of technical change

The peak spatial-average specific absorption rate (psSAR) in the head and the pinna tissues is assessed using anatomically accurate head and hand models. The first of the two mentioned studies involved nine head-, four hand- and two phone-models, the second study included six head-, four hand- and three simplified phone-models (over 400 configurations in total). In addition, both studies also evaluated the exposure using the SAM phantom. Results show no systematic differences between psSAR induced in the adult and child heads. The exposure level and its variation for different age groups may be different for particular phones, but no correlation between psSAR and model age was found. The psSAR from all exposure conditions was compared to the corresponding configurations using SAM, which was found to be conservative in the large majority of cases. (paper)

Kyoto commitments: CHP will help the UK

International Nuclear Information System (INIS)

Knowles, Michael

1998-01-01

In order to meet the United Kingdom's targets for carbon dioxide emissions reduction, agreed at the Kyoto Summit, the UK Government is promoting the use of combined heat and power (CHP) plants. Such schemes need to offer over 70% efficiency, have on-site or nearby heat uses, and allow flexibility for the export of electricity where this is appropriate. Electricity trading arrangements will need to be re-organised in line with similar commodities, in order to facilitate and promote the growth of CHP and renewable energy schemes. Financial incentives and regulation of electricity prices will also contribute to the promotion of CHP schemes, ultimately leading to reduced CO 2 pollution as a result of the growth in the UK's CHP capacity.

In this paper, SAMS, a novel health information system architecture for developing intelligent health information systems is proposed and also some strategies for developing such systems are discussed. The systems fulfilling this architecture will be able to store electronic health records of the patients using OWL ontologies, share patient records among different hospitals and provide physicians expertise to assist them in making decisions. The system is intelligent because it is rule-based, makes use of rule-based reasoning and has the ability to learn and evolve itself. The learning capability is provided by extracting rules from previously given decisions by the physicians and then adding the extracted rules to the system. The proposed system is novel and original in all of these aspects. As a case study, a system is implemented conforming to SAMS architecture for use by dentists in the dental domain. The use of the developed system is described with a scenario. For evaluation, the developed dental information system will be used and tried by a group of dentists. The development of this system proves the applicability of SAMS architecture. By getting decision support from a system derived from this architecture, the cognitive gap between experienced and inexperienced physicians can be compensated. Thus, patient satisfaction can be achieved, inexperienced physicians are supported in decision making and the personnel can improve their knowledge. A physician can diagnose a case, which he/she has never diagnosed before, using this system. With the help of this system, it will be possible to store general domain knowledge in this system and the personnel's need to medical guideline documents will be reduced.

Implementation of the Kyoto protocol

International Nuclear Information System (INIS)

2006-07-01

The Rio Earth summit in 1992 has been the starting point of an international awareness about the global risk of climatic change. At this occasion, the richest countries committed themselves to stabilize their greenhouse gas emissions and to reach by the year 2000 an emissions level equivalent to the one of 1990. The Kyoto protocol in 1997 has permitted to convert this will into juridically constraining quantitative commitments. In 2005, Russia ratified the protocol while in 2001 the USA refused to do so. Because the commitments signed are ambitious, flexibility mechanisms have been implemented: 'emission permits' (emissions trading), 'joint implementation' allowing the investments abroad for greenhouse gases abatement in another developed country, and 'clean development mechanisms' when investments are made in a developing country. The Marrakech conference of December 2001 has permitted to fix up the eligibility criteria of projects belonging to the joint implementation and clean development mechanisms. The effective implementation of these mechanisms still raises technical difficulties to evaluate and measure the effective abatement of greenhouse gas emissions. (J.S.)

Full Text Available The aim of this paper is to compare various meditative states, such as Buddhist dhyāna‑s, yogic nirbīja samādhi and nondual awareness (Tib. gñis‑med. The primary source texts I refere to are Yogasūtras of Patañjali, Ānāpānasmṛtisūtra (MN 118, Samādhisūtra (AN 4.41, The Tibetan Yogas of Dream and Sleep. I also discuss some relevant claims of contemporary empirical studies. First, I define the key terms used in Eastern meditation studies as well as in neurophenomenology, a contemporary method applied to examining the meditative states of mind, such as samādhi, dhyāna, and śamatha. Inspired by Shinzen Young, I distinguish three groups of meditative states that might be identified with nondual awareness. These three groups are: (1 the second, the third and fourth Buddhist dhyāna being equivalent to nirvicāra samādhi and nirānanda samādhi in the classical Indian yoga; (2 nirbīja samādhi and (3 nondual awareness, typical to the Mahayāna contemplative traditions. I explain why we can recognize each of the above states as nondual awareness and how they differ from each other. Then, I make a comparison between meditation practice explained in Ānāpānasmṛtisūtra and nondual awareness presented in the Tibetan Buddhism. Besides, I discuss the above kinds of mental states in terms of recent neurophenomenological findings. While doing so, I am trying to demonstrate that our understanding of meditation can benefit from the empirical studies which help us to objectify this kind of subjective experience, to some degree, if they are given an adequate place in our study.

Polarisation-dependent sum frequency generation (SFG) spectroscopy is used to investigate the orientation of molecules on metallic surfaces. In particular, self-assembled monolayers (SAMs) of dodecanethiol (DDT) and of p-nitrothiophenol (p-NTP), grown on Pt and on Au, have been chosen as models to highlight the ability of combining ppp and ssp polarisations sets (representing the polarisation of the involved beams in the conventional order of SFG, Vis and IR beam) to infer orientational information at metallic interfaces. Indeed, using only the ppp set of data, as it is usually done for metallic surfaces, is not sufficient to determine the full molecular orientation. We show here that simply combining ppp and ssp polarisations enables both the tilt and rotation angles of methyl groups in DDT SAMs to be determined. Moreover, for p-NTP, while the SFG active vibrations detected with the ppp polarisation alone provide no orientational information, however, the combination with ssp spectra enables to retrieve the tilt angle of the p-NTP 1,4 axis. Though orientational information obtained by polarisation-dependent measurements has been extensively used at insulating interfaces, we report here their first application to metallic surfaces.

2011-01-01

Full Text Available Abstract Background Next Generation Sequencing (NGS technology generates tens of millions of short reads for each DNA/RNA sample. A key step in NGS data analysis is the short read alignment of the generated sequences to a reference genome. Although storing alignment information in the Sequence Alignment/Map (SAM or Binary SAM (BAM format is now standard, biomedical researchers still have difficulty accessing this information. Results We have developed a Graphical User Interface (GUI software tool named SAMMate. SAMMate allows biomedical researchers to quickly process SAM/BAM files and is compatible with both single-end and paired-end sequencing technologies. SAMMate also automates some standard procedures in DNA-seq and RNA-seq data analysis. Using either standard or customized annotation files, SAMMate allows users to accurately calculate the short read coverage of genomic intervals. In particular, for RNA-seq data SAMMate can accurately calculate the gene expression abundance scores for customized genomic intervals using short reads originating from both exons and exon-exon junctions. Furthermore, SAMMate can quickly calculate a whole-genome signal map at base-wise resolution allowing researchers to solve an array of bioinformatics problems. Finally, SAMMate can export both a wiggle file for alignment visualization in the UCSC genome browser and an alignment statistics report. The biological impact of these features is demonstrated via several case studies that predict miRNA targets using short read alignment information files. Conclusions With just a few mouse clicks, SAMMate will provide biomedical researchers easy access to important alignment information stored in SAM/BAM files. Our software is constantly updated and will greatly facilitate the downstream analysis of NGS data.

Kyoto, coal and sharing the cost burden

International Nuclear Information System (INIS)

Daley, J.

1998-01-01

Parties to the UN Framework Convention on Climate Change (the Rio Treaty) at their first conference in 1995 agreed that the commitments entered into under the Convention were 'not adequate' to achieve its objective. These nations determined to proceed to strengthen those commitments under a protocol to be prepared for the third conference at Kyoto. Also it was to contain 'quantified emissions limitation objectives' (binding targets) on the industrial countries. For such targets to be consistent with Australia's interests, they would need to recognise Australia's relatively fast population and economic growth (both of which imply relatively faster growth in emissions), the increasing preponderance of energy intensive industries in the Australian economy, and our dependence on the export of energy intensive manufactures (like aluminium and other metals) and direct export of fossil fuels (including coal and natural gas). Major parties to the protocol negotiations - the USA and the EU - were advocates of uniform percentage emissions reductions from 1990 levels. Uniform percentage reductions, however intuitively appealing, impose widely different costs on different parties on account of their different circumstances. Australia would have been penalised by uniform reductions because our projected business-as-usual emissions trajectory is relatively steep, and measures adopted internationally to mitigate greenhouse gas emissions impact disproportionately on this economy (notably on account of reduced demand for Australian coal). The accompanying charts depict ABAREs 'less stringent' emissions scenario - addressing a goal of stabilising industrial countries' emissions of C0 2 rather than reducing them. ABARE's simulation for Australia by sector shows big negative impacts on output of non-ferrous metals, iron and steel, and coal. The metals industries, directly or indirectly are the coal industry's most important domestic customers. It is argued that because of the impact

The Seismic Aftershock Monitoring System (SAMS) for OSI - Experiences from IFE14

An on-site inspection (OSI) is the third of four elements of the verification regime of the Comprehensive Nuclear-Test-Ban Treaty (CTBT). The sole purpose of an OSI is to confirm whether a nuclear weapon test explosion or any other nuclear explosion has been carried out in violation of the treaty and to gather any facts which might assist in identifying any possible violator. It thus constitutes the final verification measure under the CTBT if all other available measures are not able to confirm the nature of a suspicious event. The Provisional Technical Secretariat (PTS) carried out the Integrated Field Exercise 2014 (IFE14) in the Dead Sea Area of Jordan from 3 November to 9. December 2014. It was a fictitious OSI whose aim was to test the inspection capabilities in an integrated manner. The technologies allowed during an OSI are listed in the Treaty. The aim of the Seismic Aftershock Monitoring System (SAMS) is to detect and localize aftershocks of low magnitudes of the triggering event or collapses of underground cavities. The locations of these events are expected in the vicinity of a possible previous explosion and help to narrow down the search area within an inspection area (IA) of an OSI. The success of SAMS depends on the main elements, hardware, software, deployment strategy, the search logic and not least the effective use of personnel. All elements of SAMS were tested and improved during the Built-Up Exercises (BUE) which took place in Austria and Hungary. IFE14 provided more realistic climatic and hazardous terrain conditions with limited resources. Significant variations in topography of the IA of IFE14 in the mountainous Dead Sea Area of Jordan led to considerable challenges which were not expected from experiences encountered during BUE. The SAMS uses mini arrays with an aperture of about 100 meters and with a total of 4 elements. The station network deployed during IFE14 and results of the data analysis will be presented. Possible aftershocks of

A comparative study on the energy policies in Japan and Malaysia in fulfilling their nations' obligations towards the Kyoto Protocol

Lau, Lee Chung; Tan, Kok Tat; Lee, Keat Teong; Mohamed, Abdul Rahman

2009-01-01

Global warming and the associated changes in the world climate pattern have been accepted world wide as the gravest threat to humanity in the 20th century. To mitigate the impacts of global warming, the Kyoto Protocol was established in 1997 with the objective of reducing global greenhouse gases (GHGs) emission, in particular carbon dioxide (CO 2 ), by 5.2% below 1990 levels. Developed nations that ratified the Protocol are committed to GHG reduction targets while developing nations are encouraged to reduce GHG emissions on a voluntary basis. Since most of the GHGs emissions come from the energy sector, energy policy plays an important role in fulfilling the Kyoto Protocol obligations. This year marks the beginning of the commitment period for the 2012 Kyoto Protocol. In this case, it would be worthwhile to compare the energy policies in Malaysia and Japan as these nations move towards fulfilling their obligations towards the Kyoto Protocol; bearing in mind that both countries ratified the Protocol, but that Japan commits a reduction target of 6% while Malaysia bears no obligation. Based on the comparison, recommendations were made on how a developing nation like Malaysia could adopt the policies implemented in Japan to suit local conditions and contribute significantly to GHG reduction.

Kyoto Protocol implementation in Serbia as precognition of sustainable energetic and economic development

International Nuclear Information System (INIS)

Golusin, Mirjana; Munitlak Ivanovic, Olja

2011-01-01

The paper gives reasons for low energy efficiency typical of the Serbian economy, which is based on outdated and dirty technologies. The comparison of selected economic indicators and indicators of energy efficiency in both Serbia and the European Union points out the benefits of the Kyoto Protocol implementation due to the growth of competitiveness in the global market. Serbia has no obligation to reduce GHG emissions, the authors point to the proposals whose implementation along with the mechanisms of the Protocol can enable Serbia the access to markets that trade GHG emissions and the access to dedicated funds, self-financing or attracting foreign investments to raise energy efficiency, which will be accompanied by adequate economic benefits. A similar principle can be applied in all countries that are not obliged to reduce GHG emissions. The application of different mechanisms aiming to increase energy efficiency in Serbia, could contribute to the increase of GDP annual growth rate from 5% to 7%, which cannot be achieved by any other economic instrument. Energy efficiency, which is actually a question of competitiveness of each economy, can finance itself through the mechanisms of the Kyoto Protocol by selling excess emissions resulting from improved energy efficiency. - Research highlights: → Serbia is a country with the outdated technology and low energy efficiency values. → Sustainable economic and energetic growth can be stirred by inserting Kyoto Protocol. → By investing in modern technology Serbia could lessen emission into the atmosphere. → Cut of emission in the atmosphere could help reaching certain carbon credit values. → By selling the carbon credit Serbia could do economic growth of 5-7% on a year level.

Detailed Physical Trough Model for NREL's Solar Advisor Model: Preprint

Energy Technology Data Exchange (ETDEWEB)

Wagner, M. J.; Blair, N.; Dobos, A.

2010-10-01

Solar Advisor Model (SAM) is a free software package made available by the National Renewable Energy Laboratory (NREL), Sandia National Laboratory, and the US Department of Energy. SAM contains hourly system performance and economic models for concentrating solar power (CSP) systems, photovoltaic, solar hot-water, and generic fuel-use technologies. Versions of SAM prior to 2010 included only the parabolic trough model based on Excelergy. This model uses top-level empirical performance curves to characterize plant behavior, and thus is limited in predictive capability for new technologies or component configurations. To address this and other functionality challenges, a new trough model; derived from physical first principles was commissioned to supplement the Excelergy-based empirical model. This new 'physical model' approaches the task of characterizing the performance of the whole parabolic trough plant by replacing empirical curve-fit relationships with more detailed calculations where practical. The resulting model matches the annual performance of the SAM empirical model (which has been previously verified with plant data) while maintaining run-times compatible with parametric analysis, adding additional flexibility in modeled system configurations, and providing more detailed performance calculations in the solar field, power block, piping, and storage subsystems.

The Kyoto Meteor Radar is a monostatic coherent pulsed Doppler radar operating on the frequency of 31.57 MH. The system is computer controlled and uses radio interferometry for echo height determination. The antenna, an improvement, can be directed either to the north or the east. The system has been continuously collecting data on winds at meteor heights by radar observation. The meteor echo rate was also measured, the echo rate distribution with height and the daily variation in height integrated echo rate are discussed. Investigations of atmospheric tides are being pursued by cooperative observations. A novel approach to the study of gravity waves was attempted using the meteor radar which is able to detect the horizontal propagation of the waves by observing the changing phase through the region illuminated by the radar

The road from Kyoto : A U.S. industry view

Energy Technology Data Exchange (ETDEWEB)

O`Keefe, W.F. [American Petroleum Inst., Washington, DC (United States)

1998-05-01

An American industry perspective of the Kyoto Protocol and its ability to produce a viable solution to global warming was offered. The Protocol would require most industrialized nations (including Canada and the United States) to cut their carbon dioxide emissions by 6 to 8 per cent below 1990 levels by year 2008 to 2012. Developing countries would not have to meet this target. It was argued that this set of targets and timetables assumes that climate risks are known with great certainty, when in fact, the long term risks of climate change are highly uncertain and near-term risks are small. It was also argued that developing countries account for more than half of the growth in CO{sub 2} emissions, therefore, their exemption from the Kyoto Protocol would make the Protocol ineffective against even a moderate warming scenario. Furthermore, the Protocol has the potential to create reactionary incentives for energy-intensive industries to move their facilities and jobs to countries without the curbs on CO{sub 2} emissions. It was suggested that a better climate policy would include all countries in CO{sub 2} reductions. It would be less expensive to achieve a target CO{sub 2} atmospheric concentration by curbing emissions slowly at first, developing technology to do so more cheaply and moving more aggressively in later years. The reality is that if the climate policy is too expensive, it is less practical and more difficult to achieve, both economically and politically. 1 tab., 2 figs.

Flexible mechanisms in the corporate greenhouse: implementation of the Kyoto Protocol and the globalization of the electric power industry

Energy Technology Data Exchange (ETDEWEB)

Schreuder, Y.; Sherry, C. [University of Delaware, Newark, DE (United States). Center for Energy and Environmental Policy

2001-07-01

The contradictions and unresolved tensions between economic globalization and climate change negotiations have added urgency to the climate change debate. The paper argues that the declining role of the nation state in the global economy and the increasing reach of transnational corporations throughout the world present a serious challenge to the environmental integrity and success of international environmental treaties such as the Kyoto Protocol. In particular efficacy and equity of the flexible mechanism under the Kyoto Protocol are questioned as illustrated by the patterns of Foreign Direct Investment (FDI) of the US electric power industry in the developing world. US FDI in the electric power sectors of developing countries supports continued carbon-intensive development patterns which will make the long-term goals of the Kyoto Protocol more difficult to achieve. Consequently, FDI raises questions about justifiability of giving credit to Annex I countries through CDM projects undertaken by transnational electric power corporations. 13 refs.

To present results of the Kyoto Global Consensus Meeting, which was convened to develop global consensus on (1) classification of chronic gastritis and duodenitis, (2) clinical distinction of dyspepsia caused by Helicobacter pylori from functional dyspepsia, (3) appropriate diagnostic assessment of gastritis and (4) when, whom and how to treat H. pylori gastritis. Twenty-three clinical questions addressing the above-mentioned four domains were drafted for which expert panels were asked to formulate relevant statements. A Delphi method using an anonymous electronic system was adopted to develop the consensus, the level of which was predefined as ≥80%. Final modifications of clinical questions and consensus were achieved at the face-to-face meeting in Kyoto. All 24 statements for 22 clinical questions after extensive modifications and omission of one clinical question were achieved with a consensus level of >80%. To better organise classification of gastritis and duodenitis based on aetiology, a new classification of gastritis and duodenitis is recommended for the 11th international classification. A new category of H. pylori-associated dyspepsia together with a diagnostic algorithm was proposed. The adoption of grading systems for gastric cancer risk stratification, and modern image-enhancing endoscopy for the diagnosis of gastritis, were recommended. Treatment to eradicate H. pylori infection before preneoplastic changes develop, if feasible, was recommended to minimise the risk of more serious complications of the infection. A global consensus for gastritis was developed for the first time, which will be the basis for an international classification system and for further research on the subject.

Carbon emissions: the economic benefits of the Kyoto Protocol

Leo, G.A. de; Gatto, M.

2001-01-01

The third Conference of the Parties in Kyoto set the target of reducing greenhouse-gas emissions by an average of 5.3 per cent with respect to 1990 values by 2008 - 2012. One of the main objections to the protocol's ratification is that compliance would pose an unbearable economic burden on the countries involved. But we show here that this is not the case if costs apart from the direct costs of energy production are also considered. Costs are also incurred in rectifying damage to human health, material goods, agriculture and the environment related to greenhouse-gas emissions. (author)

The liberalization of the Greek electric market (Law 2773/99, updated with Laws 3175/2003 and 3426/2005 for incorporating Directive 2003/54 into the Greek legislation) is in its final structural transformation, which includes the fact that from 1.7.2007 each customer can select its electricity provider. This new status together with the procedure towards the formation of a post-Kyoto plan, raise the need of examining different energy saving strategies in the consumption side for evaluating their economic and environmental consequences. Such strategies may be useful for the decision makers or the electricity retail companies. This paper examines the influence of several post-Kyoto electricity consumption strategies in the Greek interconnected electric system for the period 2005-2025. The aim of the paper is to be used as a decision makers' tool for investigating the potential of electricity consumption policies. The results show that policies related either to seasonal peak demand control, or targeting at the total electric consumption lead to significant gains and emission reduction. Moreover the influence of factors, such as the weather conditions, the discount rate of the energy investments, the fuel prices evolution and the consumers' behavior linkage with oil prices are examined

Sam68 and T-STAR are members of the STAR family of proteins that directly link signal transduction with post-transcriptional gene regulation. Sam68 controls the alternative splicing of many oncogenic proteins. T-STAR is a tissue-specific paralogue that regulates the alternative splicing of neuronal pre-mRNAs. STAR proteins differ from most splicing factors, in that they contain a single RNA-binding domain. Their specificity of RNA recognition is thought to arise from their property to homodimerize, but how dimerization influences their function remains unknown. Here, we establish at atomic resolution how T-STAR and Sam68 bind to RNA, revealing an unexpected mode of dimerization different from other members of the STAR family. We further demonstrate that this unique dimerization interface is crucial for their biological activity in splicing regulation, and suggest that the increased RNA affinity through dimer formation is a crucial parameter enabling these proteins to select their functional targets within the transcriptome.

Molecular tilt-dependent and tyrosine-enhanced electron transfer across ITO/SAM/[DPPC–Au NP–Tyrosine] Janus nanoparticle junction

Enhanced interfacial electron transfer (ET) across the otherwise insulating indium tin oxide/alkanethiol self-assembled monolayer (SAM)/redox molecule junction was accomplished when a Janus gold nanoparticle (JNP) protected by bioinspired phosphatidylcholine (DPPC) lipid and tyrosine amino acid ligands was anchored on it. In addition to the most theoretical and experimental investigations on the distance-dependent ET across Metal–Organic SAM–Nanoparticle (NP) architectures, the current results succinctly illustrate molecular tilt angle of the SAM and the characteristic of JNP as key factors in expediting the ET rate via electron tunneling. In the absence of JNP, electron tunneling with a tunneling factor β = 1.1 Å{sup −1} across the SAM was the rate-limiting step, evidenced from electrochemical impedance spectroscopy (EIS). The apparent electron transfer rate constant (k{sub app}{sup 0}) for anchored SAM was enhanced by at least one order of magnitude than the DPPC-only protected nanoparticle, suggesting the potential role of tyrosine towards the enhanced ET. The asymmetric and biogenic nature of the construct sheds light on a potential bioelectronic device for novel electronic attributes.Graphical abstractEntry of TOC .

The multi-state energy landscape of the SAM-I riboswitch: A single-molecule Förster resonance energy transfer spectroscopy study

RNA (ribonucleic acid) molecules are highly flexible biopolymers fluctuating at physiological temperatures among many different conformations that are represented by minima in a hierarchical conformational free energy landscape. Here we have employed single-molecule FRET (smFRET) to explore the energy landscape of the B. subtilis yitJ SAM-I riboswitch (RS). In this small RNA molecule, specific binding of an S-adenosyl-L-methionine (SAM) ligand in the aptamer domain regulates gene expression by inducing structural changes in another domain, the expression platform, causing transcription termination by the RNA polymerase. We have measured smFRET histograms over wide ranges of Mg2+ concentration for three RS variants that were specifically labeled with fluorescent dyes on different sites. In the analysis, different conformations are associated with discrete Gaussian model distributions, which are typically fairly broad on the FRET efficiency scale and thus can be extremely challenging to unravel due to their mutual overlap. Our earlier work on two SAM-I RS variants revealed four major conformations. By introducing a global fitting procedure which models both the Mg2+ concentration dependencies of the fractional populations and the average FRET efficiencies of the individual FRET distributions according to Mg2+ binding isotherms, we were able to consistently describe the histogram data of both variants at all studied Mg2+ concentrations. With the third FRET-labeled variant, however, we found significant deviations when applying the four-state model to the data. This can arise because the different FRET labeling of the new variant allows two states to be distinguished that were previously not separable due to overlap. Indeed, the resulting five-state model presented here consistently describes the smFRET histograms of all three variants as well as their variations with Mg2+ concentration. We also performed a triangulation of the donor position for two of the constructs

Drilled samples of mudstone from the Sheepbed unit at Yellowknife Bay were analyzed by MSL instruments including the Sample Analysis at Mars (SAM) and Chemistry and Mineralogy (CheMin) instruments in MSL's Analytical Laboratory. CheMin analyses revealed the first in situ X-ray diffraction based evidence of clay minerals on Mars, which are likely trioctahedral smectites (e.g., saponite) and comprise approx 20% of the mudstone sample (e.g., Bristow et al., this meeting). SAM analyses, which heated the mudstone samples to 1000 C and monitored volatiles evolved to perform in situ evolved gas analysis mass spectrometry (EGA-MS), resulted in a H2O trace exhibiting a wide evolution at temperatures smectite interlayer H2O, and structural H2O/OH from bassanite and akaganeite (identified by CheMin) and H2O/OH from amorphous phases in the sample. The high temperature H2O is consistent with the evolution of H2O from the dehydroxylation of the smectite clay mineral. Comparison to EGA-MS data collected under SAM-like conditions on a variety of clay mineral reference materials indicate that a trioctahedral smectite, such as saponite, is most consistent with the high temperature H2O evolution observed. There may also be SAM EGA-MS evidence for a small high temperature H2O evolution from scoop samples from the Yellowknife Bay Rocknest sand shadow bedform. As in the mudstone samples, this evolution may indicate the detection of smectite clays, and the idea that minor clays may be present in Rocknest materials that could be expected to be at least partially derived from local sources is reasonable. But, because smectite clays were not definitively observed in CheMin analyses of Rocknest materials, they must be present at much lower abundances than the approx 20% observed in the mudstone samples. This potential detection underscores the complementary nature of the MSL CheMin and SAM instruments for investigations of martian sample mineralogy. Information on the nature of Yellowknife

Selective translational repression of HIV-1 RNA by Sam68DeltaC occurs by altering PABP1 binding to unspliced viral RNA

Directory of Open Access Journals (Sweden)

Soros Vanessa

2008-10-01

Full Text Available Abstract HIV-1 structural proteins are translated from incompletely spliced 9 kb and 4 kb mRNAs, which are transported to the cytoplasm by Crm1. It has been assumed that once in the cytoplasm, translation of incompletely spliced HIV-1 mRNAs occurs in the same manner as host mRNAs. Previous analyses have demonstrated that Sam68 and a mutant thereof, Sam68ΔC, have dramatic effects on HIV gene expression, strongly enhancing and inhibiting viral structural protein synthesis, respectively. While investigating the inhibition of incompletely spliced HIV-1 mRNAs by Sam68ΔC, we determined that the effect was independent of the perinuclear bundling of the viral RNA. Inhibition was dependent upon the nuclear export pathway used, as translation of viral RNA exported via the Tap/CTE export pathway was not blocked by Sam68ΔC. We demonstrate that inhibition of HIV expression by Sam68ΔC is correlated with a loss of PABP1 binding with no attendant change in polyadenosine tail length of the affected RNAs. The capacity of Sam68ΔC to selectively inhibit translation of HIV-1 RNAs exported by Crm1 suggests that it is able to recognize unique characteristics of these viral RNPs, a property that could lead to new therapeutic approaches to controlling HIV-1 replication.

Nuclear power for greenhouse gas mitigation under the Kyoto protocol: The Clean Development Mechanism (CDM)

International Nuclear Information System (INIS)

Rogner, H.-H.

2000-01-01

At the 43rd regular session of the IAEA General Conference, Member States requested the IAEA to help countries in assessing nuclear power's role in light of global environmental challenges and energy needs. Such assistance should include support for implementing national case studies, and facilitating access to relevant information about nuclear power's role in achieving sustainable development in developing countries and in mitigating GHG emissions. The dissemination of information on CDM is of particular importance to developing countries, so as to enable Member States interested in the mechanism to take an active and informed role in the debate regarding the Kyoto Protocol and eligible CDM technologies. Therefore, the Secretariat organized a series of information seminars, workshops and training courses for Member States on the Kyoto Protocol, the Clean Development Mechanism, Joint Implementation and Emissions Trading with particular emphasis on the potential role of nuclear power for GHG mitigation. On request, the Secretariat also provided training and assistance to several Member States in the preparation of national case studies that explore the potential role of nuclear power as a CDM technology. These case studies will be presented by the respective national study teams during this side event at the 44th IAEA General Conference. Within the general criteria included in the Kyoto Protocol, the decision on which technologies are eligible for GHG mitigation under the flexibility mechanisms is a sovereign decision of each country

Kyoto and beyond : A plan of action to meet and exceed Manitoba's Kyoto targets

International Nuclear Information System (INIS)

2002-10-01

This document represents the next step in Manitoba's effort to mitigate the effects of climate change. A message from the Manitoba Premier and the Minister of Conservation of Manitoba are included in the introduction. The Action Plan is based in part on the discussion among climate experts and public input gathered in the course of the 2001 task force and the 2001 public forum on climate change. A rise in average global temperatures is affecting most of the planet, which is due in part to the upsetting of the balance of greenhouse gases in the atmosphere as a result of human activities. It is affecting weather patterns, water, agriculture, forests, health and welfare, and life in the North. The Manitoba government is committed to meeting and exceeding the reduction targets set under the Kyoto Protocol through renewable electricity, Selkirk conversion, ethanol, methane capture, and other measures targeted toward industry. Energy efficiency also plays a big part in the process of reducing greenhouse gas emissions. The government is leading by example, and also investing in knowledge. It is promoting technology development and innovation while enhancing awareness and understanding. All sectors are being encouraged to implement appropriate measures. The various initiatives undertaken by each department and organization under each of those headings are described. figs

Commitments obtained by the Kyoto protocol will end in 2012. An impressive series of conferences - Bali (2007), Copenhagen (2009), Cancun (2010) to mention the main ones - were organised to prepare the post-2012 regime. Everything was supposed to be decided at the Copenhagen meeting but the state representatives came up against the obstacle. The pre-Copenhagen hope has given place to disillusion and has led to a turn-off towards a weekly coordinated regime which requires a strategic revision of approaches. This book presents the lessons learnt from the relative failure of these negotiations and proposes new paths for the future. It puts forward some strategic stakes that have to be taken into account for the future: the equity between very heterogeneous countries and populations, the industrial competitiveness, the carbon leaks and the violation of the most ambitious climate policies due to the heterogeneity of commitment levels, and the geopolitical reality. The world will have to live for a long time with heterogeneous carbon prices, themselves reflecting heterogeneous commitment levels. New modalities have to be defined which would manage to combine justice and efficiency. Two complementary paths are developed in this book: the establishing of adjustment mechanisms at borders and of international sectoral agreements. (J.S.)

Ocean iron fertilization in the context of the Kyoto protocol and the post-Kyoto process

International Nuclear Information System (INIS)

Bertram, Christine

2010-01-01

Ocean iron fertilization is currently discussed as a potential measure to mitigate climate change by enhancing oceanic CO 2 uptake. Its mitigation potential is not yet well explored, and carbon offsets generated through iron fertilization activities could currently not be traded on regulated carbon markets. Still, commercial interests in ocean iron fertilization already exist, which underlines the need to investigate a possible regulatory framework for it. To this end, I first discuss important basic aspects of ocean iron fertilization, namely its scientific background, quantitative potential, side effects, and costs. In a second step, I review regulatory aspects connected to ocean iron fertilization, like its legal status and open access issues. Moreover, I analyze how the regulations for afforestation and reforestation activities within the framework of the Kyoto Clean Development Mechanism (CDM) could be applied to ocean iron fertilization. Main findings are that the quantitative potential of ocean iron fertilization is limited, that costs are higher than initially hoped, and that potential adverse side effects are severe. Moreover, the legal status of ocean iron fertilization is currently not well defined, open access might cause inefficiencies, and the CDM regulations could not be easily applied to ocean iron fertilization.

The Kyoto University critical assembly experimental facilities belong to the Kyoto University Research Reactor Institute, and are the versatile critical assembly constructed for experimentally studying reactor physics and reactor engineering. The facilities are those for common utilization by universities in whole Japan. During more than ten years since the initial criticality in 1974, various experiments on reactor physics and reactor engineering have been carried out using many experimental facilities such as two solidmoderated cores, a light water-moderated core and a neutron generator. The kinds of the experiment carried out were diverse, and to find out the required data from them is very troublesome, accordingly it has become necessary to make a data base which can be processed by a computer with the data accumulated during the past more than ten years. The outline of the data base, the data base CAEX using personal computers, the data base supported by a large computer and so on are reported. (Kako, I.)

How the negotiators tackled the 'hot air' issue for the second commitment period of the Kyoto Protocol

International Nuclear Information System (INIS)

2013-02-01

In 1997, when the Kyoto Protocol was approved, developed countries set their greenhouse gas (GHG) reduction commitments in relation to a 'base year' level. For the Kyoto Protocol, the year 1990 was chosen in most cases. However, irrespective of GHG mitigation action, the countries of the former Soviet Union have seen their emissions of greenhouse gases significantly decreasing after the collapse of the USSR. Given that their emissions were and still are today far below the commitments they established in 1997, these countries have a significant surplus of allowances referred to as 'hot air'. Before the COP 18 that took place in Doha (Qatar) late 2012, many countries and observers raised concern about this 'hot air'. Typically, there were two separate questions: What should we do with the accumulated surplus from the first commitment period of the Kyoto Protocol (CP1)? And will a new 'hot air' be created during the second commitment period (CP2)? This analysis explores the implications of the decisions made in Doha, using the case of Ukraine to illustrate responses to the questions raised. Indeed, as the European Union regulation forbids European countries to use CP1 units to achieve CP2 targets, Ukraine is the principal country committing to CP2 with a substantial reserve of CP1 units

Methyl group balance in brain and liver: role of choline on increased S-adenosyl methionine (SAM) demand by chronic arsenic exposure.

Science.gov (United States)

Ríos, Rosalva; Santoyo, Martha E; Cruz, Daniela; Delgado, Juan Manuel; Zarazúa, Sergio; Jiménez-Capdeville, María E

2012-11-30

Arsenic toxicity has been related to its interference with one carbon metabolism, where a high demand of S-adenosylmethionine (SAM) for arsenic methylation as well as a failure of its regeneration would compromise the availability of methyl groups for diverse cellular functions. Since exposed animals show disturbances of methylated products such as methylated arginines, myelin and axon membranes, this work investigates whether alterations of SAM, choline and phosphatidylcholine (PC) in the brain of arsenic exposed rats are associated with myelin alterations and myelin basic protein (MBP) immunoreactivity. Also these metabolites, morphologic and biochemical markers of methyl group alterations were analyzed in the liver, the main site of arsenic methylation. In adult, life-long arsenic exposed rats through drinking water (3 ppm), no changes of SAM, choline and PC concentrations where found in the brain, but SAM and PC were severely decreased in liver accompanied by a significant increase of choline. These results suggest that choline plays an important role as methyl donor in arsenic exposure, which could underlie hepatic affections observed when arsenic exposure is combined with other environmental factors.

The Mars Science Laboratory (MSL) is scheduled for launch in 2011. The science objectives for MSL are to assess the past or present biological potential, to characterize the geology, and to investigate other planetary processes that influence habitability at the landing site. The Sample Analysis at Mars (SAM) is a key instrument on the MSL payload that will explore the potential habitability at the landing site [1]. In addition to searching for organic compounds, SAM will have the capability to characterized evolved gases as a function of increasing temperature and provide information on the mineralogy of volatile-bearing phases such as carbonates, sulfates, phyllosilicates, and Fe-oxyhydroxides. The operating conditions in SAM ovens will be maintained at 30 mb pressure with a He carrier gas flowing at 1 sccm. We have previously characterized the thermal and evolved gas behaviors of volatile-bearing species under reduced pressure conditions that simulated operating conditions of the Thermal and Evolved Gas Analyzer (TEGA) that was onboard the 2007 Mars Phoenix Scout Mission [e.g., 2-8]. TEGA ovens operated at 12 mb pressure with a N2 carrier gas flowing at 0.04 sccm. Another key difference between SAM and TEGA is that TEGA was able to perform differential scanning calorimetry whereas SAM only has a pyrolysis oven. The operating conditions for TEGA and SAM have several key parameter differences including operating pressure (12 vs 30 mb), carrier gas (N2 vs. He), and carrier gas flow rate (0.04 vs 1 sccm). The objectives of this study are to characterize the thermal and evolved gas analysis of calcite under SAM operating conditions and then compare it to calcite thermal and evolved gas analysis under TEGA operating conditions.

The Sample Analysis at Mars (SAM) instrument aboard the Mars Science Laboratory rover has analyzed 10 samples from Gale Crater. All SAM evolved gas analyses have yielded a multitude of volatiles (e.g, H2O, SO2, H2S, CO2, CO, NO, O2, HC1). The objectives of this work are to 1) Characterize the evolved H2O, SO2, CO2, and O2 gas traces of sediments analyzed by SAM through sol 1178, 2) Constrain sediment mineralogy/composition based on SAM evolved gas analysis (SAM-EGA), and 3) Discuss the implications of these results releative to understanding the geochemical history of Gale Crater.

Radical SAM Enzymes in the Biosynthesis of Ribosomally Synthesized and Post-translationally Modified Peptides (RiPPs

2017-11-01

Full Text Available Ribosomally-synthesized and post-translationally modified peptides (RiPPs are a large and diverse family of natural products. They possess interesting biological properties such as antibiotic or anticancer activities, making them attractive for therapeutic applications. In contrast to polyketides and non-ribosomal peptides, RiPPs derive from ribosomal peptides and are post-translationally modified by diverse enzyme families. Among them, the emerging superfamily of radical SAM enzymes has been shown to play a major role. These enzymes catalyze the formation of a wide range of post-translational modifications some of them having no counterparts in living systems or synthetic chemistry. The investigation of radical SAM enzymes has not only illuminated unprecedented strategies used by living systems to tailor peptides into complex natural products but has also allowed to uncover novel RiPP families. In this review, we summarize the current knowledge on radical SAM enzymes catalyzing RiPP post-translational modifications and discuss their mechanisms and growing importance notably in the context of the human microbiota.

The characterisation of the chemical and mineralogical composition of solid surface samples collected with the Curiosity rover is a primary objective of the SAM experiment. These data should provide essential clues on the past habitability of Gale crater. Amongst the SAM suite of instruments [1], SAM-GC (Gas Chromatograph) is devoted to identify and quantify volatiles evolved from the thermal (heating up to about 900°C)/chemical (derivatization procedure) treatment of any soil sample collected by the Curiosity rover. With the aim to search for potential organic molecules outgassed from the samples, SAM-GC analytical channels composed of thermal-desorption injector, and a MXT-CLP or a MXT-Q chromatographic column was chosen to achieve all the measurements done up today, with the aim to separate of a wide range of volatile inorganic and organic molecules. Four solid samples have been analyzed with GCMS, one sand sample collected at the Rocknest site, two rock samples (John Klein and Cumberland respectively) collected at the Yellowknife Bay site using the Curiosity driller, and one rock sample collected at the Kimberly site. All the measurements were successful and they produced complex chromatograms with both detectors used for SAM GC, i.e. a thermal conductivity detector and the SAM quandrupole mass spectrometer. Their interpretation already revealed the presence of an oxychlorine phase present in the sample which is at the origin of chlorohydrocarbons clearly identified [2] but this represents only a fraction of the GCMS signal recorded [3,4]. This work presents a systematic comparison of the GCMS measurements done for the different samples collected, supported by reference data obtained in laboratory with different spare models of the gas chromatograph, with the aim to bring new elements of interpretation of the SAM measurements.

The Kyoto Protocol attempts through political negotiations to guide participating industrialized countries' greenhouse gas (GHG) emissions from a positive growing trend, to reach a peak point (or turning point), and then be reduced to a negative growth. That means the relationship between decreasing GHG emissions and economic growth may be described by an inverted-U curve (or called a bell-shaped curve), which is consistent with the concept of the Environmental Kuznets Curve (EKC) hypothesis. This research observed that the economic development and GHG emissions in Economies in Transition (EITs) exhibit a hockey-stick curve trend (or called quasi-L-shape curve), that also generates a lot of 'hot air' which is significant to the implementation of the Kyoto Protocol. In addition, through the analysis of single-country time series data and GDP data, this research demonstrated that statistical data for most of the Annex II countries do not possess evidence that supports the EKC hypothesis for GHG emissions. The results from this study also indicated that the 38 industrialized countries are unable to meet their targets under the Kyoto Protocol within the specified time period, which are probably caused by the econometric method's inability to predict accurately the extents and development of innovative technologies and Clean Development Mechanism (CDM) projects. If the international community truly wants to reduce the GHG emissions, the effectiveness of the existing international framework for emissions reduction needs to be reconsidered seriously, and the global cooperation mechanism also needs to be greatly enhanced.

Immediate and delayed anxiety- and depression-like profiles in the adolescent Wistar-Kyoto rat model of endogenous depression following postweaning social isolation.

Science.gov (United States)

Shetty, Reshma A; Sadananda, Monika

2017-03-01

In order to understand links that exist between inherited risk or predisposition, brain and behavioural development, endocrine regulation and social/environmental stimuli, animal models are crucial. The Wistar-Kyoto (WKY) rat has been shown to have validity as a model of adult and adolescent depression. While sex- and age-specific differences in some of the face, predictive and construct validities of the model such as depression-like behaviours have been established, anhedonia and anxiety using other induced anxiety paradigms such as elevated plus maze remain equivocal. First, post-weaning social isolation effects on inherent and induced anxiety behaviours were tested during two critical time periods, early- and mid-adolescence. Isolation induced immediate effects on novel environment-induced hyperactivity and anxiety-related behaviours. Adolescent WKYs demonstrated reduced 50-kHz ultrasonic vocalizations suggesting agoraphobia-like behaviours. Second, isolated rats, despite being subsequently social-/group-housed demonstrated longer lasting effects on social interaction measures and anhedonia. This establishes that the depression-like profile observed during early- and mid-adolescence persists into late adolescence and early adulthood in WKY. Further, that interventions at a later stage during adolescence may not be able to reverse early adolescent effects in the context of pre-disposition, thus highlighting the irreversibility of being double-hit during critical time periods of brain and behavioural development and maturation.

Climate economics: post-Kyoto tracks

Godard, Olivier; Ponssard, Jean-Pierre

2011-01-01

Commitments obtained by the Kyoto protocol will end in 2012. An impressive series of conferences - Bali (2007), Copenhagen (2009), Cancun (2010) to mention the main ones - were organised to prepare the post-2012 regime. Everything was supposed to be decided at the Copenhagen meeting but the state representatives came up against the obstacle. The pre-Copenhagen hope has given place to disillusion and has led to a turn-off towards a weekly coordinated regime which requires a strategic revision of approaches. This book presents the lessons learnt from the relative failure of these negotiations and proposes new paths for the future. It puts forward some strategic stakes that have to be taken into account for the future: the equity between very heterogeneous countries and populations, the industrial competitiveness, the carbon leaks and the violation of the most ambitious climate policies due to the heterogeneity of commitment levels, and the geopolitical reality. The world will have to live for a long time with heterogeneous carbon prices, themselves reflecting heterogeneous commitment levels. New modalities have to be defined which would manage to combine justice and efficiency. Two complementary paths are developed in this book: the establishing of adjustment mechanisms at borders and of international sectoral agreements. (J.S.)

Increased Energy Efficiency in Slovenian Industry - A Contribution to the Kyoto Target

Selan, B.; Urbancic, A.

1998-01-01

In Slovenia the actual fast growth of greenhouse emissions will require substantial efforts to fulfil the target set in Kyoto. The end-use emissions in the in the industrial sectors represented one third of the total CO 2 emissions in the country in 1996. The cost-effective potential in the sector for CO 2 emission reduction is significant. In the paper, the most important ongoing energy efficiency activities in the industrial sector are presented: information and awareness building, energy advising to larger industrial consumers, energy audition programme, demonstration programme of energy efficiency technologies, financial incentives for energy efficiency investment and the energy efficiency investment fund. A CO 2 tax has been in force since 1997. The results of an evaluation of energy efficiency strategies in industry in the frame of the project 'Integrated resource planning for the energy efficiency in Slovenia' are discussed from the viewpoint of greenhouse gases reduction targets set by Slovenia, and a brief information on the ongoing and expected post Kyoto activities and studies is given. The most important points of the future GHG reduction strategy related to industrial sector in Slovenia will be focused on intensified energy efficiency programme, increased combined heat and power production (CHP), and the effects of incentives through the CO 2 tax.

The objective of the ISOE Expert Group on Occupational Radiation Protection in Severe Accident Management and Post-accident Recovery (EG-SAM) is to develop a report on best radiation protection management procedures for proper radiation protection job coverage during severe accident initial response and recovery efforts to identify good radiation protection practices and to organise and communicate radiation protection lessons learned from previous reactor accidents. The outcome of the work will be a new ISOE publication on Occupational Radiation Protection in severe accident management that will find broad use within the NPP radiation protection community. The EG-SAM has finalized an interim report which was presented at the Washington workshop. The interim report covered the following topics: RP Management and Organisation; RP Training and Exercises related to Severe Accident Management; Facility Configuration and Readiness; Overall Approach for Worker Protection; Monitoring and Managing the Radioactive Releases and Contamination; Key Lessons Learned from Past Accidents; Conclusions. Utilities and Regulatory Authorities have identified the factors and aspects which play key roles in achieving good practices on occupational radiation protection in severe accident management and post-accident recovery: knowledge, experience, technology, regulatory requirements and guidance, worker involvement, information exchange, training aspects, etc. They have analysed and quantified their impact on worker doses, and submitted recommendations for further work. The next step will be a final meeting of the EG-SAM for the finalization of the report with workshop inputs before its submission for approval

Complying with the Kyoto Protocol under uncertainty: Taxes or tradable permits?

International Nuclear Information System (INIS)

Quirion, Philippe

2010-01-01

The Kyoto Protocol allocates tradable emission allowances (AAUs) to developed countries, but they are free to choose a set of policy instruments to comply with these targets. We compare two different policy instruments: a tax and purely domestic tradable permits, for the European Union, the US and Japan. Information on abatement costs and international permit price is imperfect and stems from nine global economic models. For a country party to the Protocol, the benefit of emission reduction is that it can sell more or has to buy less AAUs. We show that in this context, permits entail a slightly lower expected cost than a tax for the US and Japan, whereas both instruments yield an almost equal outcome for Europe. Applying Weitzman's framework (Prices vs. quantities, RES, 1974) in this context, we show the importance of the positive correlation between costs and benefits: technology shocks that lead to low abatement costs in one country generally lead to low abatement costs in other countries too, thereby leading to a low international permit price in the true-up period.

The Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change (COP3) will be held in Kyoto in December 1997. Described herein are the current status and issues of the convention. USA and Japan, which hold important keys to set up the abatement target, have issued no proposals concretely at the current AGBM (Ad-hoc Group Berlin Mandate) 7, and the conference for the concrete targets will be decided in the next AGBM 8 to be held in October. The final target will be set by the ministerial segment of COP3, because the negotiations for the treaty are political in nature. USA proposes reduction at a uniform, realistic rate, and Japan proposes reduction at a uniform rate or setting up the emission target per capita, each being different from reduction at a much higher uniform rate proposed by EU. Within EU, however, 10% out of 15% reduction rate it proposes is agreed by the member countries, and the remaining rate of % may not be agreed. It is necessary for the advanced parties to set up realistic and legally binding solutions, including ratification by USA, which can persuade the developing countries. tab.1

Kyoto Protocol, constraint or opportunity for coal based electricity producers

International Nuclear Information System (INIS)

Balasoiu, Constantin; Alecu, Sorin

2006-01-01

Coming into force of Kyoto Protocol (KP) in February 2005, as a result of its signing by Russian Federation, created the lawfulness of its provisions and mechanisms in order to reduce the average emission of Greenhouse Gases (GHG) at a global level down to 5.2 %. Passing this environment problem from a constrained area (regulations, directives) to an opportunity area (business) created the possibility that the achievement of KP objectives to be not an exclusive financial task of 'polluting actors', but opened the opportunity of bringing on stage all the necessary elements of a modern business environment: banks, investments from founds companies, consultants, buyers, sellers, stocks exchange. Until now, the investments and emissions transactions based by KP mechanisms at the worldwide level was focused on renewable energy area. Because for the most of countries, including Romania, the production of electricity based on fossil fuels (special coal) is one of the main option, bringing the KP mechanisms in operation in this area is difficult for at least two reasons: - the investments are huge; - the emissions reduction is not spectacular. In these circumstances, this paper gives an overview of the present GHG emission market, transaction mechanisms on this market and of the ways through which coal based electricity producers from Romania can access this market. We consider that the filtration of the information in this area from electricity producer point of view makes the content of this paper a good start for a new approach of environment management and its conversion from constraint (financial resources consumer) to opportunity ( financial resources producer). The paper contains are as follows: 1. Kyoto Protocol at a glance; 2. Emission trading mechanisms; 2.1. Transaction mechanisms under KP; 2.1.1. Joint Implementation (JI); 2.1.2 Clean Development Mechanism (CDM); 2.1.3. Emissions Trading (ET); 2.2. Other transactions mechanisms; 2.2.1. European Union Emissions

EV car sharing/rental pilot project in Kyoto : an outline of the project

This paper presented a demonstration project in the City of Kyoto, Japan, which is aimed at determining if a Public Car System is an economically viable option for the twenty first century. The Kyoto electric vehicle (EV) car sharing project comprises advanced systems for EV reservation, check-out and return, and fleet operation and management. The most unique feature of this project is that it utilizes the ever expanding Internet and advanced mobile phones with Internet capabilities. Initially, 35 two-seater EVs will be shared by employees and visitors for business-related trips on weekdays and by tourists on weekends. The car sharing will be only short-term for only a single trip. The EV can be checked out and returned to any service depot located at railroad stations, major business centers and tourist attractions for user convenience. The ultimate goal of the project is to promote energy and resource conservation while providing adequate levels of mobility for people. Converting existing fleets to EVs which produce no exhaust gases is considered to be a viable solution to the problem of air pollution caused by traffic jams. tabs., figs.

Elp3 and RlmN: A tale of two mitochondrial tail-anchored radical SAM enzymes in Toxoplasma gondii.

Science.gov (United States)

Padgett, Leah R; Lentini, Jenna M; Holmes, Michael J; Stilger, Krista L; Fu, Dragony; Sullivan, William J

2018-01-01

Radical S-adenosylmethionine (rSAM) enzymes use a 5'-deoxyadensyl 5'-radical to methylate a wide array of diverse substrates including proteins, lipids and nucleic acids. One such enzyme, Elongator protein-3 (TgElp3), is an essential protein in Toxoplasma gondii, a protozoan parasite that can cause life-threatening opportunistic disease. Unlike Elp3 homologues which are present in all domains of life, TgElp3 localizes to the outer mitochondrial membrane (OMM) via a tail-anchored trafficking mechanism in Toxoplasma. Intriguingly, we identified a second tail-anchored rSAM domain containing protein (TgRlmN) that also localizes to the OMM. The transmembrane domain (TMD) on Toxoplasma Elp3 and RlmN homologues is required for OMM localization and has not been seen beyond the chromalveolates. Both TgElp3 and TgRlmN contain the canonical rSAM amino acid sequence motif (CxxxCxxC) necessary to form the 4Fe-4S cluster required for tRNA modifications. In E. coli, RlmN is responsible for the 2-methlyadenosine (m2A) synthesis at purine 37 in tRNA while in S. cerevisiae, Elp3 is necessary for the formation of 5-methoxycarbonylmethyl-2-thiouridine (mcm5s2U) at the wobble tRNA position. To investigate why these two rSAM enzymes localize to the mitochondrion in Toxoplasma, and whether or not TgRlmN and TgElp3 possess tRNA methyltransferase activity, a series of mutational and biochemical studies were performed. Overexpression of either TgElp3 or TgRlmN resulted in a significant parasite replication defect, but overexpression was tolerated if either the TMD or rSAM domain was mutated. Furthermore, we show the first evidence that Toxoplasma tRNAGlu contains the mcm5s2U modification, which is the putative downstream product generated by TgElp3 activity.

The Long Road from Ljubljana to Kyoto: Implementing Emission Trading Mechanisms and CO2 Tax

Full Text Available According to the Kyoto Protocol, Slovenia is required to reduce GHG emissions to an average of 8% below base year 1986 emissions in the period 2008-2012. Slovenia established different measures for reducing GHG emissions long before its ratification. It was first transition country who implemented CO2 tax in the 1997. Several changes in CO2 tax have not brought the desired results. CO2 emissions have actually increased. At the beginning of 2005, Slovenia joined other EU member states by implementing the emissions trading instrument, defined by new EU Directive. At the same time, Slovenia has adopted a new CO2 tax system, which is compatible with the new circumstances. The main purpose of this paper is to present the characteristics of Slovenian approach to national allocation plan for emissions trading and analyze the problems of the CO2 tax in Slovenia. Paper also describes the compliance cost of achieving the Kyoto target and expected movements on the Slovenian allowances market.

Formation of the supported planar bilayer of dipalmitoylphosphatidylcholine (DPPC) on SiO{sub 2} surfaces modified with the self-assembled monolayer (SAM) of octadecyltrichlorosilane (OTS) has been investigated by atomic force microscopy (AFM). DPPC was deposited by the fusion of vesicles on SiO{sub 2} surfaces with OTS-SAM islands of different sizes and densities. The DPPC bilayer membrane formed self-organizingly on the SiO{sub 2} surface with small and sparse OTS islands, while did not when the OTS islands were larger and denser. The relative size between the vesicles and the SiO{sub 2} regions is the critical factor for the formation of the DPPC bilayer membrane.

The Wistar-Kyoto (WKY) rat is an established depression model characterized by elevated anxiety- and depression-like behavior across a variety of tests. Here we further characterized specific behavioral and functional domains relevant to depression that are altered in WKY rats. Moreover, since early-life experience potently shapes emotional behavior, we also determined whether aspects of WKYs' phenotype were modifiable by early-life factors using neonatal handling or maternal separation. We first compared WKYs' behavior to that of Sprague-Dawley (SD), Wistar, and Spontaneously Hypertensive (SHR) rats in: the open field test, elevated plus maze, novelty-suppressed feeding test, a social interaction test, and the forced swim test (FST). WKYs exhibited high baseline immobility in the FST and were the only strain to show increased immobility on FST Day 2 vs. Day 1 (an indicator of learned helplessness). WKYs also showed greater social avoidance, along with enlarged adrenal glands and hearts relative to other strains. We next tested whether neonatal handling or early-life maternal separation stress influenced WKYs' behavior. Neither manipulation affected their anxiety- and depressive-like behaviors, likely due to a strong genetic underpinning of their phenotype. Our findings indicate that WKY rats are a useful model that captures specific functional domains relevant to clinical depression including: psychomotor retardation, behavioral inhibition, learned helplessness, social withdrawal, and physiological dysfunction. WKY rats appear to be resistant to early-life manipulations (i.e., neonatal handling) that are therapeutic in other strains, and may be a useful model for the development of personalized anti-depressant therapies for treatment resistant depression.

WKYs also showed greater social avoidance, along with enlarged adrenal glands and hearts relative to other strains. We next tested whether neonatal handling or early-life maternal separation stress influenced WKYs’ behavior. Neither manipulation affected their anxiety- and depressive-like behaviors, likely due to a strong genetic underpinning of their phenotype. Our findings indicate that WKY rats are a useful model that captures specific functional domains relevant to clinical depression including: psychomotor retardation, behavioral inhibition, learned helplessness, social withdrawal, and physiological dysfunction. WKY rats appear to be resistant to early-life manipulations (i.e. neonatal handling that are therapeutic in other strains, and may be a useful model for the development of personalized anti-depressant therapies for treatment resistant depression.

2013-01-01

By using a simple random-walk model, we simulate the growth of a self-assembled monolayer (SAM) pattern generated in dip pen nanolithography (DPN). In this model, the SAM pattern grows mainly via the serial pushing of molecules deposited from the tip. We examine various SAM patterns, such as lines, crosses, and letters by changing the tip scan speed.

Creare Incorporated and NASA Goddard Space Flight Center developed and space qualified two wide range pumps (WRPs) that were included in the Sample Analysis at Mars (SAM) instrument. This instrument was subsequently integrated into the Mars Science Laboratory (MSL) "Curiosity Rover," launched aboard an Atlas V rocket in 2011, and landed on August 6, 2012, in the Gale Crater on Mars. The pumps have now operated for more than 18 months in the Gale Crater and have been evacuating the key components of the SAM instrument: a quadrupole mass spectrometer, a tunable laser spectrometer, and six gas chromatograph columns. In this paper, we describe the main design challenges and the ways in which they were solved. This includes the custom design of a miniaturized, high-speed motor to drive the turbo drag pump rotor, analysis of rotor dynamics for super critical operation, and bearing/lubricant design/selection.

In this paper we evaluate the compliance mechanisms in the Kyoto Protocol as agreed at the seventh Conference of Parties to the United Nations Framework Convention on Climate Change (UNFCCC) in Marrakech. We differ from the literature since we concentrate on the complete set of compliance rules agreed in Marrakech and, as a new element, we systematically discuss these compliance incentives in conjunction with the implicit compliance incentives: reputation protection, emission trading and banking. We conclude that effectiveness and efficiency go hand in hand for all explicit and implicit compliance incentives except one--emission trading. Trading improves efficiency but this can also occur at the cost of increasing non-compliance

Tobacco-free economy: A SAM-based multiplier model to quantify the impact of changes in tobacco demand in Bangladesh.

Husain, Muhammad Jami; Khondker, Bazlul Haque

2016-01-01

In Bangladesh, where tobacco use is pervasive, reducing tobacco use is economically beneficial. This paper uses the latest Bangladesh social accounting matrix (SAM) multiplier model to quantify the economy-wide impact of demand-driven changes in tobacco cultivation, bidi industries, and cigarette industries. First, we compute various income multiplier values (i.e. backward linkages) for all production activities in the economy to quantify the impact of changes in demand for the corresponding products on gross output for 86 activities, demand for 86 commodities, returns to four factors of production, and income for eight household groups. Next, we rank tobacco production activities by income multiplier values relative to other sectors. Finally, we present three hypothetical 'tobacco-free economy' scenarios by diverting demand from tobacco products into other sectors of the economy and quantifying the economy-wide impact. The simulation exercises with three different tobacco-free scenarios show that, compared to the baseline values, total sectoral output increases by 0.92%, 1.3%, and 0.75%. The corresponding increases in the total factor returns (i.e. GDP) are 1.57%, 1.75%, and 1.75%. Similarly, total household income increases by 1.40%, 1.58%, and 1.55%.

Among the publications of CDC Climat Research, 'Climate Reports' offer in-depth analyses on a given subject. This issue addresses the following points: During the Phase II of the European Trading Scheme, installations had the option to surrender carbon credits from project-based mechanisms of the Kyoto Protocol (CERs and ERUs). The rules set by Member States and approved by the European Commission capped the demand at around 1,400 MtCO 2 between 2008 and 2012. In the end, over 1 billion Kyoto credits (675 million CERs and 383 million ERUs) have been surrendered by EU ETS installations. What conclusions can be drawn from this unique experience in a CO 2 allowance market?

Land Use: the Kyoto protocol, the FAO definition of forest and the Italian Inventory of Forests and Carbon Stocks

Directory of Open Access Journals (Sweden)

2005-01-01

Full Text Available In 2000, after the international agreement on the Kyoto Protocol of the United Nations Framework Convention on Climate Change, the United Nation Food and Agriculture Organization decided to adopt a new set of basic forest and forest change definitions. The main change is that new definitions are no more related to land cover but to land use. The entry into force of the Kyoto Protocol requires now that national forest related data must be based on land use concept. Thus, national forest inventory shall be designed in order to collect data which are consistent with current land-use related definitions. In this paper the authors analyze the case of the Italian forest inventory.

Analyzing the Kyoto Protocol under the Marrakesh Accords. Economic efficiency and environmental effectiveness

Den Elzen, Michel G.J.; De Moor, Andre P.G.

2002-01-01

This article evaluates the environmental effectiveness and economic implications of the Kyoto Protocol (KP) after the Bonn agreement and the Marrakesh Accords. We will break it down into several components that correspond with major steps in the international process: pre-COP 6 version of the KP, with unrestricted international emissions trading but without sinks; withdrawal of the USA; and decisions on sinks in Bonn and Marrakesh. The Marrakesh Accords bring Annex-I emissions in 2010 without the USA at 0.5% under base-year levels; this corresponds to nearly 2% above the 1990-levels. The US withdrawal has by far the greatest impact in reducing the environmental effectiveness of the KP, whereas the impact of the decision on sinks is comparatively small. The US withdrawal also substantially reduces the permit demand and permit prices will drop dramatically. Hot air becomes increasingly dominant and may threaten the viability of the Kyoto Mechanisms (KM), especially in lower baseline (business-as-usual (BaU)) scenarios. Therefore, banking of hot air is of absolute importance to improve the environmental effectiveness of the protocol at moderately higher costs, while enhancing the development of a viable emission trading market. A strategy of curtailing and banking permit supply is also in the interest of the dominant seller, Russia

Recently, it has becoming increasingly important to control the organization of self-assembled monolayers (SAMs) of {omega}-functionalized thiols for its potential applications in the construction of more complex molecular architectures. In this paper, we report on the spontaneous formation of a SAM of octanedithiol (ODT) as a function of the modification time. Electrochemical techniques such as cyclic voltammetry, double layer capacitance and electrochemical impedance spectroscopy are used for the characterization of this monolayer. The increase in modification time brings about changes in the octanedithiol self-assembled monolayer (ODT-SAM) reductive desorption voltammograms that indicate an evolution toward a more ordered and compact monolayer. This trend has also been found by following the changes in the electron transfer processes of the redox probe K{sub 3}Fe(CN){sub 6}. In fact, the ODT-SAM formed at low-modification time does not significantly perturb the electrochemical response as it is typical of either a low coverage or of the presence of large defects in the layer. Upon increasing the modification time, the voltammograms of the redox probe adopt a sigmoidal shape indicating the existence of pinholes in the monolayer distributed as an array of microelectrodes. The surface coverage as well as the size and distribution of these pinholes have been determined by the impedance technique that gives a more reliable evaluation of these monolayer structural parameters.

The presence of antibiotics in aquatic environments has attracted global concern. Fenton process is an attractive yet challenging method for antibiotics degradation, especially when such a reaction can be conducted at neutral pH values. In this study, a novel composite Fe/Co catalyst was synthesized via the modification of steel converter slag (SCS) by salicylic acid-methanol (SAM) and cobalt nitrate (Co(NO 3 ) 2 ). The catalysts were characterized by N 2 -Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD), Fourier transform infrared (FT-IR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). The results indicated that the Co-SAM-SCS/H 2 O 2 Fenton-like system was very effective for sulfamethazine (SMZ) degradation at a wide pH range. At initial pH of 7.0, the degradation rate of SMZ in Co-SAM-SCS/H 2 O 2 system was 2.48, 3.20, 6.18, and 16.21 times of that in Fe-SAM-SCS/H 2 O 2 , SAM-SCS/H 2 O 2 , Co(NO 3 ) 2 /H 2 O 2 and SCS/H 2 O 2 system, respectively. The preliminary analysis suggested that high surface area of Co-SAM-SCS sample and synergistic effect between introduced Co and SAM-SCS are responsible for the efficient catalytic activity. During the degradation, three main intermediates were identified by high performance liquid chromatography-mass spectrometry (HPLC-MS) analysis. Based on this, a possible degradation pathway was proposed. The SEM images, XRD patterns and XPS spectra before and after the reactions demonstrate that the crystal and chemical structure of Co-SAM-SCS after five cycles are almost unchanged. Besides, the Co-SAM-SCS presented low iron and cobalt leaching (0.17 mg/L and 2.36 mg/L, respectively). The studied Fenton-like process also showed high degradation of SMZ in river water and municipal wastewater. The progress will bring valuable insights to develop high-performance heterogeneous Fenton-like catalysts for environmental remediation. Copyright © 2018

Latest approaches of Kyoto protocol

Recently EURELECTRIC welcome the proposal of new EC Directive concerning the inclusion in the EU Emissions Trading Scheme (ETS) of credits from the project mechanisms - Joint Implementation (JI) and Clean Development Mechanism (CDM). The proposed Directive is an amendment to the EU Emissions Trading Directive adopted in June 2003. EURELECTRIC calls for unlimited use of credits in ETS. The draft Directive provides for the application of these mechanisms to begin as of 2008, on condition that the Kyoto Protocol does actually enter into force, an event which is still dependent on Russia's ratification. Such ratification has been subject to contradictory statements from the Russian Government, and the question of whether their signature to the Protocol is forthcoming is still fraught with uncertainty. Although it is not anticipated that significant quantities of JI or CDM certified credits will be available in the period 2005-2007, those that do become available would provide some additional liquidity in the emissions trading market. There is a direct relation between the coming ETS and electricity pricing: environmental policy is the driver, based on the need to switch to a low-carbon future and manage the necessary investments in a rational manner - and emissions trading is the best solution available. Romania has good opportunities to be involved in the greenhouse gases market, both in ETS and JI mechanisms. Some JI projects between Romanian and The Netherlands are already done or underway.

Emission Trading under the Kyoto Protocol

Holtsmark, Bjart; Hagem, Cathrine

1998-12-01

This report discusses the potential gains from emission trading and raises some crucial questions. It shows that the total costs of the Kyoto Protocol could be reduced by about 95% through emission trading. Emission trading is an option also in the domestic arenas. The governments of the Annex B countries may allocate emission quotas to local enterprises as emission permits. Thus new markets for greenhouse gas emission quotas may emerge, domestically and internationally. It is emphasized that emission trading at the national and international levels must be discussed separately. The Nordic governments, for example, will find several good reasons for supporting emission trading at the international level if not necessarily domestically. The Nordic countries have already implemented domestic taxes on CO{sub 2} emissions and this tax policy could be sustained while these governments support and take part in emission trading at the international level.The report also considers a possible side effect of emission trading: free emission trading among Annex B countries could reduce the total abatement compared to a non-tradable policy as a consequence of the fact that some of the countries that are in transition to a market economy may be given emission limitations above their business-as-usual emissions. 40 refs., 7 figs., 4 tabs.

One among the main objectives of the Sample Analysis at Mars (SAM) experiment is the in situ molecular analysis of gases evolving from solid samples heated up to approximately 850 degrees Centigrade, and collected by Curiosity on Mars surface/sub-surface in Gale crater. With this aim, SAM uses a gas-chromatograph coupled to a quadrupole mass spectrometer (GC-QMS) devoted to separate, detect and identify both volatile inorganic and organic compounds. SAM detected chlorinated organic molecules produced in evolved gas analysis (EGA) experiments. Several of these were also detected by the Viking experiments in 1976. SAM also detected oxychlorine compounds that were present at the Phoenix landing site. The oxychlorines may be prevelant over much of the martian surface. The C1 to C3 aliphatic chlorohydrocarbons (chloromethane and di- and trichloromethane) detected by SAM were attributed to reaction products occurring between the oxychlorines phases and the organic compounds coming from SAM instrument background. But SAM also showed the presence of a large excess of chlorobenzene and C2 to C4 dichloroalkanes among the volatile species released by the Cumberland sample of the Sheepbed mudstone. For the first time in the history of the Mars exploration, this proved the presence of Mars indigenous organic material at the Mars' surface. However, the identification of the precursor organic compounds of these chlorohydrocarbons is difficult due to the complexity of the reactions occurring during the sample pyrolysis. Laboratory pyrolysis experiments have demonstrated that oxychlorines phases such as perchlorates and chlorates, decomposed into dioxygen and volatile chlorine bearing molecules (HCl and/or Cl2) during the pyrolysis. These chemical species can then react with the organic molecules present in the martian solid samples through oxidation, chlorination and oxychlorination processes.

The Intergovernmental Panel on Climate Change (IPCC) was established by the World Meteorological Organization and the United Nations Environment Program in 1988 to assess the available scientific, technical, and socioeconomic information in the field of climate change. The most recent report of the IPCC concluded that ``Our ability to quantify the human influence on global climate is currently limited because the expected signal is still emerging from the noise of natural variability, and because there are uncertainties in key factors. These include the magnitudes and patterns of long-term variability and the time-evolving pattern of forcing by, and response to, changes in concentrations of greenhouse gases and aerosols, and land surface changes. Nevertheless the balance of evidence suggests that there is a discernible human influence on global climate. The first and second Conference of the Parties in 1995 and 1996 agreed to address the issue of greenhouse gas emissions for the period beyond 2000, and to negotiate quantified emission limitations and reductions for the third Conference of the Parties. On December 1 through 11, 1997, representatives from more than 160 countries met in Kyoto, Japan, to negotiate binding limits on greenhouse gas emissions for developed nations. The resulting Kyoto Protocol established emissions targets for each of the participating developed countries--the Annex 1 countries--relative to their 1990 emissions levels. 114 refs., 138 figs., 33 tabs.

miCLIP-MaPseq, a Substrate Identification Approach for Radical SAM RNA Methylating Enzymes.

Although present across bacteria, the large family of radical SAM RNA methylating enzymes is largely uncharacterized. Escherichia coli RlmN, the founding member of the family, methylates an adenosine in 23S rRNA and several tRNAs to yield 2-methyladenosine (m 2 A). However, varied RNA substrate specificity among RlmN enzymes, combined with the ability of certain family members to generate 8-methyladenosine (m 8 A), makes functional predictions across this family challenging. Here, we present a method for unbiased substrate identification that exploits highly efficient, mechanism-based cross-linking between the enzyme and its RNA substrates. Additionally, by determining that the thermostable group II intron reverse transcriptase introduces mismatches at the site of the cross-link, we have identified the precise positions of RNA modification using mismatch profiling. These results illustrate the capability of our method to define enzyme-substrate pairs and determine modification sites of the largely uncharacterized radical SAM RNA methylating enzyme family.

This article notices on the internal difficulties that will be generated around the ratification of the Kyoto Protocol in developed countries as United States, Canada and Japan, given the position of industries like the vehicles and the energetic, that try to dilate the commitments assumed in December of 1997. It is emphasized in the North American case, taking into account their contribution in the global greenhouse gases emissions and the importance of their participation in an international agreement on the topic of the climate change, assuming a critical position about the Senate's decision of conditioning the agreement's ratification to the assumption of commitments of developing countries

Objective The Kyoto gastritis classification categorizes the endoscopic characteristics of Helicobacter pylori (H. pylori) infection-associated gastritis and identifies patterns associated with a high risk of gastric cancer. We investigated its efficacy, comparing scores in patients with H. pylori-associated gastritis and with gastric cancer. Methods A total of 1,200 patients with H. pylori-positive gastritis alone (n=932), early-stage H. pylori-positive gastric cancer (n=189), and successfully treated H. pylori-negative cancer (n=79) were endoscopically graded according to the Kyoto gastritis classification for atrophy, intestinal metaplasia, fold hypertrophy, nodularity, and diffuse redness. Results The prevalence of O-II/O-III-type atrophy according to the Kimura-Takemoto classification in early-stage H. pylori-positive gastric cancer and successfully treated H. pylori-negative cancer groups was 45.1%, which was significantly higher than in subjects with gastritis alone (12.7%, pgastritis scores of atrophy and intestinal metaplasia in the H. pylori-positive cancer group were significantly higher than in subjects with gastritis alone (all pgastritis classification may thus be useful for detecting these patients.

Capping the Cost of Compliance with the Kyoto Protocol and Recycling Revenues into Land-Use Projects

Full Text Available There is the concern among some countries that compliance costs with commitments under the Kyoto Protocol may be unacceptably high. There is also the concern that technical difficulties with the inclusion of land use, land-use change, and forestry activities in non-Annex I countries might lead to an effective exclusion of such activities from consideration under the Protocol. This paper is proposing a mechanism that addresses both these concerns. In essence, it is suggested that parties should be able to purchase fixed-price offset certificates if they feel they cannot achieve compliance through other means alone, such as by improved energy efficiency, increased use of renewable energy, or use of the flexible mechanisms in the Kyoto Protocol. These offset certificates would act as a price cap for the cost of compliance for any party to the Protocol. Revenues from purchase of the offset certificates would be directed to forest-based activities in non-Annex I countries such as forest protection that may carry multiple benefits including enhancing net carbon sequestration.

Full Text Available El comportamiento climático del planeta y sus consecuencias han propiciado debates sobre los modelos de desarrollo de los países responsables del deterioro acelerado del ambiente y de los fenómenos naturales por estos días recurrentes. Sin embargo, países como Estados Unidos, luego de firmar compromisos como la Convención sobre Cambio Climático, rehúsan adquirir las obligaciones del Protocolo de Kyoto, por temor a sufrir deterioro en sus economías. En este escenario, donde la nación responsable de la emisión de aproximadamente 36% de los gases efecto invernadero resultado de la acción humana en el planeta no se compromete a adoptar políticas restrictivas tendientes a hacer sus modelos de producción más amigables con la naturaleza a pesar de que dichas medidas empiezan a ser impuestas a otras naciones como condicionantes en las negociaciones comerciales internacionales, parece ser que la adopción del Protocolo de Kyoto para países en desarrollo como Colombia no es del todo benéfica.

In this article the possible effects they are analyzed that the implementation of the proposals on control emissions of greenhouse gases contained in the kyoto protocol would have about the energy system and the economy of the country. In particular, the mechanism of clean development, proposed are discussed to facilitate the execution of reduction goals agreed for the developed countries and to link to the countries in development toward a strategy of sustainable development. Use of a methodological proposal is made carried out in collaboration with the institute Paul Scherrer, consistent in the development of a combined model that integrates national models Markal, as tool for the identification of efficient technologies for the reduction of emissions in the energy sector. The results of the application exercise are presented for selection of projects that Switzerland could finance in Colombia and it thinks about the convenience of integral evaluations and definition of rules for the participation of the country in this mechanism and in the negotiations that were carried out in the coming years in this matter. It is clear that it cannot be ignored the necessity that the country goes toward a more and more rational exploitation of the natural resources

Tomato ACC synthase is inactivated by its substrate SAM, with the moiety of aminobutyrate being covalently linked to ACC synthase during the catalytic reactions. A partial purified ACC synthase (the catalytic activity 100 μmol/h·mg protein) from pellets of apple extract was incubated with [3,4 14 C] SAM. Only one radioactive peak was revealed in a C-4 reverse phase HPLC and one radioactive band on SDS-PAGE with an M.W. of 48 kDa. Apple ACC synthase in native form is resistant to V8, α-chromtrypsin and carboxylpeptidase A digestion, but effectively inactivated by trypsin and ficin, as demonstrated by both the activity assay and SAM labeling. The radioactive protein cut from the SDS-PAGE was injected to three mice, two of the mice showed responses to the protein in western blot analysis. The antibodies from mice is currently under characterization

In this way the substrates adoption methodology helps to achieve “fast, flexible, future (F3)” pharmaceutical production processes by adapting a recently designed generic modular process-plant. The supporting tools for the substrate adoption are: (1) an ontological knowledge......There is a significant cost associated with process development of a portfolio of pharmaceutical products, few of which will reach the market. Continuous processing will increase the “chemical space” which can increase development efficiency.

Recently, it has becoming increasingly important to control the organization of self-assembled monolayers (SAMs) of {omega}-functionalized thiols for its potential applications in the construction of more complex molecular architectures. In this paper, we report on the spontaneous formation of a SAM of octanedithiol (ODT) as a function of the modification time. Electrochemical techniques such as cyclic voltammetry, double layer capacitance and electrochemical impedance spectroscopy are used for the characterization of this monolayer. The increase in modification time brings about changes in the octanedithiol self-assembled monolayer (ODT-SAM) reductive desorption voltammograms that indicate an evolution toward a more ordered and compact monolayer. This trend has also been found by following the changes in the electron transfer processes of the redox probe K{sub 3}Fe(CN){sub 6}. In fact, the ODT-SAM formed at low-modification time does not significantly perturb the electrochemical response as it is typical of either a low coverage or of the presence of large defects in the layer. Upon increasing the modification time, the voltammograms of the redox probe adopt a sigmoidal shape indicating the existence of pinholes in the monolayer distributed as an array of microelectrodes. The surface coverage as well as the size and distribution of these pinholes have been determined by the impedance technique that gives a more reliable evaluation of these monolayer structural parameters.

SAM II satellite measurements during the July 1979 Poker Flat mission, yielded an aerosol extinction coefficient of 0.0004/km at 1.0 micron wavelength, in the region of the stratospheric aerosol mixing ratio peak (12-16 km). The stratospheric aerosol optical depth for these data, calculated from the tropopause through 30 km, is approximately 0.001. These results are consistent with the average 1979 summertime values found throughout the Arctic.

Why Nature Uses Radical SAM Enzymes so Widely: Electron Nuclear Double Resonance Studies of Lysine 2,3-Aminomutase Show the 5'-dAdo• "Free Radical" Is Never Free.

Horitani, Masaki; Byer, Amanda S; Shisler, Krista A; Chandra, Tilak; Broderick, Joan B; Hoffman, Brian M

2015-06-10

Lysine 2,3-aminomutase (LAM) is a radical S-adenosyl-L-methionine (SAM) enzyme and, like other members of this superfamily, LAM utilizes radical-generating machinery comprising SAM anchored to the unique Fe of a [4Fe-4S] cluster via a classical five-membered N,O chelate ring. Catalysis is initiated by reductive cleavage of the SAM S-C5' bond, which creates the highly reactive 5'-deoxyadenosyl radical (5'-dAdo•), the same radical generated by homolytic Co-C bond cleavage in B12 radical enzymes. The SAM surrogate S-3',4'-anhydroadenosyl-L-methionine (anSAM) can replace SAM as a cofactor in the isomerization of L-α-lysine to L-β-lysine by LAM, via the stable allylic anhydroadenosyl radical (anAdo•). Here electron nuclear double resonance (ENDOR) spectroscopy of the anAdo• radical in the presence of (13)C, (2)H, and (15)N-labeled lysine completes the picture of how the active site of LAM from Clostridium subterminale SB4 "tames" the 5'-dAdo• radical, preventing it from carrying out harmful side reactions: this "free radical" in LAM is never free. The low steric demands of the radical-generating [4Fe-4S]/SAM construct allow the substrate target to bind adjacent to the S-C5' bond, thereby enabling the 5'-dAdo• radical created by cleavage of this bond to react with its partners by undergoing small motions, ∼0.6 Å toward the target and ∼1.5 Å overall, that are controlled by tight van der Waals contact with its partners. We suggest that the accessibility to substrate and ready control of the reactive C5' radical, with "van der Waals control" of small motions throughout the catalytic cycle, is common within the radical SAM enzyme superfamily and is a major reason why these enzymes are the preferred means of initiating radical reactions in nature.

Economic impact assessment of Turkey's post-Kyoto vision on emission trading

For the post-Kyoto period, Turkey strongly emphasizes the establishment of national emission trading system by 2015 and its integration with the EU ETS along its accession process to the EU. In this paper, we study the mechanisms of adjustment and economic welfare consequences of various ETS regimes that Turkey considers to apply by 2020, i.e. regional ETS and international trading within the EU ETS. We conduct our analysis under the current EU 20–20–20 emission target, 20%, and also under its revised version, 30%. We find that Turkey has economic gains from linking with the EU ETS under the 20% cap, in comparison to the domestic ETSs. Despite the EU's welfare loss under linkage in comparison to the case where Turkey has domestic abatement efforts, it still prefers linking as it increases economic well being compared to the case where Turkey does not abate. Under 30% cutback, Turkey has critical output loss under linkage due to high abatement burden on the EU, while the EU is better off as it passes some of its abatement burden to Turkey. Therefore, emission quotas and their allocation across the ETS and non ETS sectors become highly critical in distributing the overall economic gains from bilateral trading. - Highlights: • We conduct welfare analysis of Turkey's post-Kyoto vision on emission trading. • Welfare impacts of having Turkey in the EU ETS via EU accession are analyzed. • Analysis is done with the current EU target of 20%, and the revised target of 30%. • Welfare impacts of linkage on both regions highly depend on the emission targets. • The EU has welfare gains when Turkey engages in abatement actions

Kyoto and beyond : the low emission path to innovation and efficiency

Torrie, R.; Parfett, R.; Steenhof, P.

This paper presents a scenario in which greenhouse gas emissions in Canada are brought down to half the current levels over the next 28 years, surpassing the Kyoto target and putting Canada on a course for even greater emission reductions in the long term. The rationale for this action is based on information which states that concentration of greenhouses gases in the upper atmosphere will continue to increase until emissions are brought down to about half their current levels on a global basis. Just to stop emissions from growing on a global level would require a reduction of about 50 per cent in Canada. It is noted that achieving the Kyoto targets would not stop atmospheric concentrations of greenhouse gases from continuing to rise unless they are implemented with a plan to reduce emissions even further for the long term. The design principles that were followed in coming up with a plan to achieve 50 per cent emission reductions include: an energy demand focus; efficiency; renewable energy sources; energy services that are provided by technologies that are environmentally benign; energy services provided at least cost; and diversity of energy sources. It was concluded that the key to achieving sustainable reductions in greenhouse gas emissions is on the demand side of the energy economy, suggesting there is a need for basic changes in the climate policy debate in Canada. Studies have confirmed that technological innovation and energy saving measures can meet environmental objectives while creating economic growth and employment opportunities. It was suggested that these measures could provide economic renewal in regions that are in decline. They will also reduce air pollution which is becoming a major economic and public health issue in several Canadian communities. refs., tabs., figs

Tracking the MSL-SAM methane detection source location Through Mars Regional Atmospheric Modeling System (MRAMS)

Pla-García, Jorge

2016-04-01

1. Introduction: The putative in situ detection of methane by Sample Analysis at Mars (SAM) instrument suite on Curiosi-ty at Gale crater has garnered significant attention because of the potential implications for the presence of geological methane sources or indigenous Martian organisms [1, 2]. SAM reported detection of back-ground levels of atmospheric methane of mean value 0.69±0.25 parts per billion by volume (ppbv) at the 95% confidence interval (CI). Additionally, in four sequential measurements spanning a 60-sol period, SAM observed elevated levels of methane of 7.2±2.1 ppbv (95% CI), implying that Mars is episodically producing methane from an additional unknown source. There are many major unresolved questions regard-ing this detection: 1) What are the potential sources of the methane release? 2) What causes the rapid decrease in concentration? and 3) Where is the re-lease location? 4) How spatially extensive is the re-lease? 5) For how long is CH4 released? Regarding the first question, the source of methane, is so far not identified. It could be related with geo-logical process like methane release from clathrates [3], serpentinisation [4] and volcanism [5]; or due to biological activity from methanogenesis [6]. To answer the second question, the rapid decrease in concentration, it is important to note that the photo-chemical lifetime of methane is of order 100 years, much longer than the atmospheric mixing time scale, and thus the gas should tend to be well mixed except near a source or shortly after an episodic release. The observed spike of 7 ppb from the background of System (MRAMS). The model was focused on rover locations using nested grids with a spacing of 330 meters on the in-nermost grid that is centered over the landing [8, 9]. MRAMS is ideally suited for this investigation; the model is explicitly designed to simulate Mars' at-mospheric circulations at the mesoscale and smaller with realistic, high-resolution surface properties [10, 11

Paper presented to the Commission des transports et de l'environnement in the context of the general consultation concerning the implementation of the Kyoto Protocol in Quebec

International Nuclear Information System (INIS)

2003-02-01

Climate change is a major issue facing Quebec's population and future generations. The scientific community generally agrees on the negative effects resulting from global climate change on human health, the environment and the economy. In 1997, the Kyoto Protocol was adopted by industrialized countries, whereby countries agreed to reduce their emissions of greenhouse gases (GHG) by a certain percentage, calculated from 1990 levels. In the case of Canada, this percentage was 6 per cent, for the first commitment period covering 2008-2012. Quebec's performance on the issue of GHG emissions compares favorably to that of other Canadian provinces, even to that of other industrialized countries. Canada ratified the Kyoto Protocol in December 2002. The Quebec National Assembly called for a parliamentary committee to meet on 18 February 2003 on the implementation of the Kyoto Protocol. Hydro-Quebec, since 1997, has favored the ratification of the Kyoto Protocol by the Canadian government. In this document, Hydro-Quebec makes its position known in the context of this debate and the commercial context of the electric power industry in 2003. The first section of the document was devoted to the favorable performance of Hydro-Quebec, on the retroactive and prospective aspects of GHG emissions with regard to the entire electric power industry in Canada. In the second section, an explanation was provided, in the context of deregulation of the electricity market in North America, on the implementation of the Kyoto Protocol in Quebec and in Canada and how it becomes a major commercial issue for Hydro-Quebec. The analysis was conducted in light of the mandate of Hydro-Quebec to provide a secure and reliable service to its customers. refs., 1 fig

Rainfall declines over Queensland from 1951-2007 and links to the Subtropical Ridge and the SAM

Cottrill, D A; Ribbe, J

2010-01-01

Much of southern and eastern Australia including Queensland have experienced rainfall declines over recent decades affecting agricultural production and accelerating water infrastructure development. Rainfall declines from southern Australia have now been directly related to changes in the Southern Annular Mode (SAM) and the subtropical ridge. In southern and coastal Queensland, the rainfall declines have occurred mostly in the austral summer and autumn. Observations from this region reveal the rainfall decline is correlated to an increase in the mean sea level pressure (MSLP) at many stations. The largest increases in MSLP are over southeast Queensland and coastal regions, where some of the largest rainfall declines occur. This study indicates the subtropical ridge as one of the main factors in the rainfall decline over this region. SAM is also likely to be important, although its seasonal influence, apart from winter, is harder to determine.

A new materials irradiation facility with improved control capabilities has been installed at the Kyoto University Reactor (KUR). Several deficiencies of conventional fission neutron material irradiation systems have been corrected. The specimen temperature is controlled both by an electric heater and by the helium pressure in the irradiation tube without exposure to neutrons at temperatures different from the design test conditions. The neutron spectrum is varied by the irradiation position. Irradiation dose is changed by pulling the irradiation capsule up and down during irradiation. Several characteristics of the irradiation field were measured. The typical irradiation intensity is 9.4x10 12 n/cm 2 s (>0.1 MeV) and the irradiation temperature of specimens is controllable from 363 to 773 K with a precision of ±2 K

The oxidize form was obtained from the electrochemical oxidation of a monolayer of SAM-TOA-ANTA-Co2+. The results suggest that the HRP-NHis is attached to both monolayers in a similar way; on the contrary, the desortion of the attached protein is dramatically different. Thus, whereas the ligand-Co2+ bonds are reversible, which allows that the anchored protein is easily replaced by imidazol molecules. The 3+ oxidation state of the metal does not allow the interchange of protein by the imidazol molecules.

Since the Research Reactor Institute of Kyoto University was established as an inter-university research institute in 1963, a large number of cooperative research projects have been achieved by visiting scientists and its own staff in various research fields, making use of facilities centered around the Kyoto University Reactor, as well as the other experimental facilities. Ten years ago, the construction of the 'KURRIP' data base was initiated to grasp the whole aspect of the research activities at the Institute, in commemoration of its 20th anniversary. At the present time, KURRIP contains the information on 5,910 papers published for 29 years from 1963 to 1991. As this academic year is the 30th anniversary of the Institute, the history of its research activities was reviewed again using this data base. All of the publications were classified by authors's affiliations, kinds of papers, publishers, fields of studies, and research facilities used, and their historical variations are checked and discussed.

2010-01-01

Full Text Available The present work has as main objective to build a model to identify the sun apparent movement (SAM as well as estimate the time interval in which it is above the horizon, to anywhere in the world and in any season. We begin with a brief reflection on the genesis of astronomy and some of its basic concepts, from which the model is built. The model basically consists of a transparent cylinder, in which are shown the paths of the SAM over the year. As applications of the model, are proposed some examples, such as the duration of "daylight" in different places of the globe. Making and using this model, besides the low cost and easy feasibility, provides a good understanding of the SAM.

SAM: Support Vector Machine Based Active Queue Management

International Nuclear Information System (INIS)

Shah, M.S.

2014-01-01

Recent years have seen an increasing interest in the design of AQM (Active Queue Management) controllers. The purpose of these controllers is to manage the network congestion under varying loads, link delays and bandwidth. In this paper, a new AQM controller is proposed which is trained by using the SVM (Support Vector Machine) with the RBF (Radial Basis Function) kernal. The proposed controller is called the support vector based AQM (SAM) controller. The performance of the proposed controller has been compared with three conventional AQM controllers, namely the Random Early Detection, Blue and Proportional Plus Integral Controller. The preliminary simulation studies show that the performance of the proposed controller is comparable to the conventional controllers. However, the proposed controller is more efficient in controlling the queue size than the conventional controllers. (author)

The KART (Kumatori Accelerator-driven Reactor Test facility) project started in Research Reactor Institute, Kyoto University in fiscal year 2002 with the grant by the Japanese Ministry of Education, Culture, Sports, Science and Technology. The purpose of this research project is to demonstrate the basis feasibility of accelerator driven system (ADS), studying the effect of incident neutron energy on the effective multiplication factor in a subcritical nuclear fuel system. For this purpose, a variable-energy FFAG (Fixed Field Alternating Gradient) accelerator complex is being constructed to be coupled with the Kyoto University Critical Assembly (KUCA). The FFAG proton accelerator complex consists of ion-beta, booster and main rings. This system aims to attain 1 μA proton beam with energy range from 20 to 150 MeV with a repetition rate of 120 Hz. The first beam from the FFAG complex is expected to be available by the end of FY 2005, and the experiment on ADS with KUCA and the FFAG complex (FFAG-KUCA experiment) will start in FY 2006. Before the FFAG-KUCA experiment starts, preliminary experiments with 14 MeV neutrons are currently being performed using a Cockcroft-Walton type accelerator coupled with the KUCA. Experimental data are analyzed using continuous energy Monte-Carlo codes MVP, MCNP and MNCP-X. (author)

With the use of the Kyoto University Critical Assembly (KUCA), a joint reactor laboratory course of graduate level is offered every summer since 1975 by nine associated Japanese universities (Hokkaido University, Tohoku University, Tokyo Institute of Technology, Musashi Institute of Technology, Tokai University, Nagoya University, Osaka University, Kobe University of Mercantile Marine and Kyushu University) in addition to a reactor laboratory course of undergraduate level for Kyoto University. These courses are opened for three weeks (two weeks for the joint course and one week for the undergraduate course) to students majoring in nuclear engineering and a total of 1,360 students have taken the course in the last 21 years. The joint course has been institutionalized with the background that it is extremely difficult for a single university in Japan to have her own research or training reactor. By their effort, the united faculty team of the joint course have succeeded in giving an effective, unique one-week course, taking advantage of their collaboration. Last year, an enquete (questionnaire survey) was conducted to survey the needs for the educational experiments of graduate level and precious data have been obtained for promoting reactor laboratory courses.

The United Nations Framework Convention on Climate Change (UNFCCC) was approved in 1992 to respond to the worl-wide concern about the warming of the planet. The primary target was the stabilization of the concentration of greenhouse gases in the atmosphere, in an attempt to reduce to the minimum the degradation of the environment caused by humans. By virtue of the Convention, the Parts2 are committed to reach their objectives in the reduction of the emissions. A Conference of the Parts was stablished to promote the effective application of the Convention. The third Conference of the Parts, celebrated in Kyoto (Japan, 1997) approved, by consensus, the denominated Kyoto Protocol, in which 39 developed countries and countries with economies in transition were committed to reduce their emissions of greenhouse gases between years 2008 and 2012 in a 5.2 global percent with respect to the 1990 levels. Three {sup f}lexibility mechanisms{sup w}ere stablished to help the Parts to reach their objectives: the emissions trading, the clean development mechanism and the joint implementation. Within the European Union (EU), a redistribution of the general objective among his States Members is allowed: {sup G}reenhouse gas emissions trading{sup .} (Author)

As a Party to the United Nations Framework on Climate Change (UNFCCC), since 1994 Germany has been obliged to prepare, publish and regularly update national emission inventories of greenhouse gases. In February 2005, the Kyoto Protocol entered into force. As a result, for the first time ever the international community of nations is required to implement binding action objectives and instruments for global climate protection. This leads to extensive obligations vis-a-vis the preparation, reporting and review of emissions inventories. As a result of Europe's own implementation of the Kyoto Protocol, via the adoption of EU Decision 280/20041, these requirements became legally binding for Germany in spring 2004. Pursuant to Decision 3/CP.5, all The purpose of such reports is to ensure the transparency, consistency and comparability of inventories and support the independent review process. The Secretariat of the Framework Convention on Climate Change has made submission of the inventory report a pre-requisite for performance of the agreed inventory reviews. Germany now presents its eighth National Inventory Report (NIR 2010), following its inventories for the years 1990 to 2008. This latest report covers the same period (1990 to 2008), and it describes the methods and the data sources on which the calculations are based. This year, the NIR contains, for the first time, an additional Part II, along with additional sub-chapters in the existing part, in conformance with expanded requirements under the Kyoto Protocol and the relevant decisions at the European level. Part I of the NIR presents, in Chapters 1 to 10, all the information relevant to the annual greenhouse gas inventory. Chapter 1 provides background information about climate change and about greenhouse gas inventories, as well as further information relative to the Kyoto Protocol. In addition, this chapter describes the basic principles and methods with which the emissions and sinks of the IPCC categories

Statistical shape and appearance models of bones.

When applied to bones, statistical shape models (SSM) and statistical appearance models (SAM) respectively describe the mean shape and mean density distribution of bones within a certain population as well as the main modes of variations of shape and density distribution from their mean values. The availability of this quantitative information regarding the detailed anatomy of bones provides new opportunities for diagnosis, evaluation, and treatment of skeletal diseases. The potential of SSM and SAM has been recently recognized within the bone research community. For example, these models have been applied for studying the effects of bone shape on the etiology of osteoarthritis, improving the accuracy of clinical osteoporotic fracture prediction techniques, design of orthopedic implants, and surgery planning. This paper reviews the main concepts, methods, and applications of SSM and SAM as applied to bone. Copyright © 2013 Elsevier Inc. All rights reserved.

Why Nature Uses Radical SAM Enzymes so Widely: Electron Nuclear Double Resonance Studies of Lysine 2,3-Aminomutase Show the 5′-dAdo• “Free Radical” Is Never Free

Horitani, Masaki; Byer, Amanda S.; Shisler, Krista A.; Chandra, Tilak; Broderick, Joan B.; Hoffman, Brian M.

2015-01-01

Lysine 2,3-aminomutase (LAM) is a radical S-adenosyl-L-methionine (SAM) enzyme and, like other members of this superfamily, LAM utilizes radical-generating machinery comprising SAM anchored to the unique Fe of a [4Fe-4S] cluster via a classical five-membered N,O chelate ring. Catalysis is initiated by reductive cleavage of the SAM S–C5′ bond, which creates the highly reactive 5′-deoxyadenosyl radical (5′-dAdo•), the same radical generated by homolytic Co–C bond cleavage in B12 radical enzymes. The SAM surrogate S-3′,4′-anhydroadenosyl-L-methionine (anSAM) can replace SAM as a cofactor in the isomerization of L-α-lysine to L-β-lysine by LAM, via the stable allylic anhydroadenosyl radical (anAdo•). Here electron nuclear double resonance (ENDOR) spectroscopy of the anAdo• radical in the presence of 13C, 2H, and 15N-labeled lysine completes the picture of how the active site of LAM from Clostridium subterminale SB4 “tames” the 5′-dAdo• radical, preventing it from carrying out harmful side reactions: this “free radical” in LAM is never free. The low steric demands of the radical-generating [4Fe-4S]/SAM construct allow the substrate target to bind adjacent to the S–C5′ bond, thereby enabling the 5′-dAdo• radical created by cleavage of this bond to react with its partners by undergoing small motions, ~0.6 Å toward the target and ~1.5 Å overall, that are controlled by tight van der Waals contact with its partners. We suggest that the accessibility to substrate and ready control of the reactive C5′ radical, with “van der Waals control” of small motions throughout the catalytic cycle, is common within the radical SAM enzyme superfamily and is a major reason why these enzymes are the preferred means of initiating radical reactions in nature.

Approximately 50% of the deaths of children under the age of 5 can be attributed to undernutrition, which also encompasses severe acute malnutrition (SAM). Diarrhoea is strongly associated with these deaths and is commonly diagnosed solely based on stool frequency and consistency obtained through maternal recall. This trial aims to determine whether this approach is equivalent to a 'directly observed method' in which a health care worker directly observed stool frequency using diapers in hospitalised children with complicated SAM. This study was conducted at 'Moyo' Nutritional Rehabilitation Unit, Queen Elizabeth Central Hospital, Malawi. Participants were children aged 5-59 months admitted with SAM. We compared 2 days of stool frequency data obtained with next-day maternal-recall versus a 'gold standard' in which a health care worker observed stool frequency every 2 h using diapers. After study completion, guardians were asked their preferred method and their level of education. We found poor agreement between maternal recall and the 'gold standard' of directly observed diapers. The sensitivity to detect diarrhoea based on maternal recall was poor, with only 75 and 56% of diarrhoea cases identified on days 1 and 2, respectively. However, the specificity was higher with more than 80% of children correctly classified as not having diarrhoea. On day 1, the mean stool frequency difference between the two methods was -0.17 (SD; 1.68) with limits of agreement (of stool frequency) of -3.55 and 3.20 and, similarly on day 2, the mean difference was -0.2 (SD; 1.59) with limits of agreement of -3.38 and 2.98. These limits extend beyond the pre-specified 'acceptable' limits of agreement (±1.5 stool per day) and indicate that the 2 methods are non-equivalent. The higher the stool frequency, the more discrepant the two methods were. Most primary care givers strongly preferred using diapers. This study shows lack of agreement between the assessment of stool frequency in SAM

This third meeting of the Parties to the UN Framework Convention on Climate Change, held from 1-10 December 1997 in Kyoto/Japan, on which high expectations had been placed, just as on the Berlin meeting two years ago, has certainly not come up to expectations, but still agreed upon a Protocol that can be called an important signpost in international policy for protection of the environment. The envisaged greenhouse gas reduction by 5.2 per cent (of 1990 emissions) laid down in the Protocol, to be achieved by the industrialized countries either individually or by Joint Implementation over the period from 2008 until 2012, is a positive result considering the present situation. Although the agreed cutback falls short of the figures given by climate experts (who demand at least a 20% reduction by the year 2005), the obligation of the USA, the worldwide biggest emitter of greenhouse gases, to achieve a mandatory minimum cutback in emissions of 7% can be considered a big success.

Wenngleich damit die Forderung der Klimaforscher (mindestens 20%-Reduktion bis 2005) nicht erreicht wurde, muss die 7%-Minderungsverpflichtung des weltgroessten Treibhausgasemittenten USA als grosser Erfolg gesehen werden.

Full Text Available Bioengineering of dermal and epidermal cells on surface modified substrates is an active area of research. The cytotoxicity, maintenance of cell phenotype and long-term functionality of human dermal fibroblast (HDF cells on conducting indium tin oxide (ITO and semi-conducting, silicon (Si and gallium arsenide (GaAs, surfaces modified with self-assembled monolayers (SAMs containing amino (–NH2 and methyl (–CH3 end groups have been investigated. Contact angle measurements and infrared spectroscopic studies show that the monolayers are conformal and preserve their functional end groups. Morphological analyses indicate that HDFs grow well on all substrates except GaAs, exhibiting their normal spindle-shaped morphology and exhibit no visible signs of stress or cytoplasmic vacuolation. Cell viability analyses indicate little cell death after one week in culture on all substrates except GaAs, where cells died within 6 h. Cells on all surfaces proliferate except on GaAs and GaAs-ODT. Cell growth is observed to be greater on SAM modified ITO and Si-substrates. Preservation of cellular phenotype assessed through type I collagen immunostaining and positive staining of HDF cells were observed on all modified surfaces except that on GaAs. These results suggest that conducting and semi-conducting SAM-modified surfaces support HDF growth and functionality and represent a promising area of bioengineering research.

The Curiosity rover is exploring sedimentary rock sequences in Gale Crater for evidence of habitability and searching for organic compounds using the Sample Analysis at Mars (SAM) instrument suite. SAM includes a gas chromatograph mass spectrometer (GC-MS) and pyrolysis ovens. SAM has the ability to perform wet chemistry experiments, one of which uses tetramethylammonium hydroxide (TMAH) thermochemolysis to liberate bound lipids, making them sufficiently volatile for detection by GC-MS. To determine the effectiveness of the SAM-like TMAH experiment on fatty acid methyl ester (FAME) biomarker identification, rock and sediment samples were collected from a variety of Mars analog environments including iron oxides from a modern mineral precipitate and older surface gossan at Iron Mountain, CA, as well as modern acid salt and neutral lake sediments with mixed iron oxides and clays from Western Australia; siliceous sinter from recently inactive and modern near-vent Icelandic hot springs deposits; modern carbonate ooids from The Bahamas, and organic-rich shale from Germany. Samples underwent pyrolysis with TMAH. Fatty acids were analyzed by pyro-GC-MS using a SAM-like heating ramp (35°C/min) as well as a 500°C flash on a Frontier pyrolyzer and Agilent GC-MS instrument. Results reveal that FAMEs were detectable with the TMAH experiment in nearly all samples. Low molecular weight (MW) C6:0-C10:0 FAMEs were present in all samples, medium MW C11:0-C18:2 FAMEs were present in select samples, and high MW (HMW) C20:0-C30:0 FAMEs were present in the shale sample. Many of these samples exhibited an even-over-odd carbon number preference, indicating biological production. These experiments demonstrate that TMAH thermochemolysis with SAM-like pyro-GC-MS is effective in fatty acid analysis from natural Mars-analog samples that vary in mineralogy, age, and microbial community input. HMW FAMEs are not detected in iron-dominated samples, and may not be detectable at low

Swedish industry and Kyoto - An assessment of the effects of the European CO2 emission trading system

International Nuclear Information System (INIS)

Braennlund, Runar; Lundgren, Tommy

2007-01-01

We assess the effects on Swedish industry input demands and output of different climate policy scenarios connected to energy policy induced by the Kyoto protocol. We use a unique dataset containing firm-level data on outputs and inputs between 1991 and 2001 to estimate a factor demand model, which we use to simulate different policy scenarios. Sector-specific estimation suggests that the proposed quadratic profit function specification exhibits properties and robustness that are consistent with economic theory; that is, all own-price elasticities are negative and all output elasticities are positive. Furthermore, the elasticities show that the input demands are, in most cases, relatively inelastic. Simulation of the model for six different policy scenarios reveal that effects on the Swedish base industry of a EU-level permit-trading system depends on (i) the removal or maintenance of the current CO 2 tax, (ii) the price of permits, and (iii) the future price of electricity. Our analysis shows that changes in electricity price may be more important than the price of permits for some sectors. (author)

This paper reviews uncertainties in the oil sands industry in relation to climate change, greenhouse gas emissions and the Kyoto Protocol. Other issues contributing to uncertainties in the industry were also discussed, including water and natural gas issues, refinery capacity and markets, price and exchange rates as well as capital availability and project cost overruns. The potential economic impact of the Kyoto Protocol on oil sands was outlined with prices per barrel. Government regulations were examined in the context of the evolving expectations of the Canadian public. U.S. actions on climate change were examined at the federal and state level. Emissions trading systems were reviewed with reference to a post 2012 regime. The 2005 budget was discussed, along with the Canadian legislative agenda and domestic offsets program, as well as the regulatory agenda in June of 2005. Post 2012 issues were examined, including discussions on the next commitment period, with reference to the fact that there was no support for new commitments among developing countries but that domestic pressures was building in the U.S. for air and climate regulations. Pressures from shareholders and the scientific community were discussed. Emissions trading in the European Union was reviewed. Stabilization goals will mean significant cuts to emissions in order to accommodate growth. Scenario planning and climate change uncertainties were also reviewed. The benefits of scenario planning in complex situations were outlined and were seen to encourage the development of strategic options. Issues concerning environmental stewardship and possible responses by the Unites States were discussed. Three scenarios were outlined: that climate change is not man-made and all the problems will go away; that technology will evolve to accommodate changes; and that policy will be insensitive to the economy, technology will lag and the energy sector will be faced with much higher costs.

Radical S-adenosyl-L-methionine (SAM) en-zymes comprise a vast superfamily catalyzing diverse reactions essential to all life through ho-molytic SAM cleavage to liberate the highly-reactive 5-deoxyadenosyl radical (5-dAdo•). Our recent observation of a catalytically compe-tent organometallic intermediate Ω that forms dur-ing reaction of the radical SAM (RS) enzyme py-ruvate formate-lyase activating-enzyme (PFL-AE) was therefore quite surprising, and led to the question of its broad relevance in the superfamily. We now show that Ω in PFL-AE forms as an in-termediate under a variety of mixing order condi-tions, suggesting it is central to catalysis in this enzyme. We further demonstrate that Ω forms in a suite of RS enzymes chosen to span the totality of superfamily reaction types, implicating Ω as essential in catalysis across the RS superfamily. Finally, EPR and electron nuclear double reso-nance spectroscopy establish that Ω involves an Fe-C5 bond between 5-dAdo• and the [4Fe-4S] cluster. An analogous organometallic bond is found in the well-known adenosylcobalamin (co-enzyme B12) cofactor used to initiate radical reac-tions via a 5'-dAdo• intermediate. Generation of a 5'-dAdo• intermediate via homolytic metal-carbon bond cleavage thus appears to be similar for Ω and coenzyme B12. However coenzyme B12 is involved in enzymes catalyzing of only a small number (~12) of distinct reactions, while the RS superfamily has more than 100,000 distinct se-quences and over 80 reaction types character-ized to date. The appearance of Ω across the RS superfamily therefore dramatically enlarges the sphere of bio-organometallic chemistry in Nature.

In situ measurements of atmospheric methane have been made over a 5-year period at Gale Crater on Mars using the Tunable Laser Spectrometer (TLS) instrument in the Sample Analysis at Mars (SAM) suite on the Curiosity rover. We report two important observations: (i) a background level of mean value of 0.41 ±0.11 (2sem) that is about 5 times lower than some model predictions based on generation from UV degradation of micro-meteorites or interplanetary dust delivered to the martian surface; (ii) "spikes" of elevated levels of 7 ppbv attributed to episodic releases from small local sources, probably to the north of Gale crater1. Reports of plumes, patches or episodic releases of methane in the Martian atmosphere have to date eluded explanation in part because of their lack of repeatability in time or location. Our in situ measurements of the background methane levels exhibit a strong, repeatable seasonal variability. The amplitude of the observed seasonal cycle is 3 times greater than both that expected from the annual sublimation and freezing of polar carbon dioxide and that expected from methane production from ultraviolet (UV) degradation of exogenously-delivered surface material. The observed large seasonal variation in the background, and sporadic observations of higher pulses of 7 ppbv appear consistent with localized small sources of methane release from Martian surface reservoirs that may be occurring throughout the planet. We will present our updated data set, correlations of Mars methane with various other measurements from SAM, REMS, RAD and ChemCam instruments on Curiosity, as well as empirical models of UV surface insolation, and provide preliminary interpretation of results. 1 "Mars Methane Detection and Variability at Gale Crater", C.

Surveillance and Measurement System (SAMS). Innovative Technology Summary Report

International Nuclear Information System (INIS)

2001-01-01

The United States Department of Energy (DOE) continually seeks safer and more cost-effective technologies for the decontamination and decommissioning (D and D) of nuclear facilities. The Deactivation and Decommissioning Focus Area (DDFA) of the DOE's Office of Science and Technology sponsors large-scale demonstration and deployment projects (LSDDPs) to identify and demonstrate technologies that will be safer and more cost-effective. At these LSDDPs, developers and vendors of improved or innovative technologies showcase products that are potentially beneficial to the DOE's projects as well as others in the D and D community. Benefits sought include decreased health and safety risks to personnel and the environment, increased productivity, and decreased cost of operation. The Idaho National Engineering and Environmental Laboratory (INEEL) LSDDP generated a list of need statements defining specific needs or problems where improved technologies could be incorporated into ongoing D and D tasks. Advances in characterization technologies are continuously being sought to decrease the cost of sampling and increase the speed of obtaining results. Currently it can take as long as 90 days to receive isotopic analysis of radioactive samples from laboratories on soil, liquid, and paint samples. The cost to analyze these types of samples for radionuclides is about $150 per sample. This demonstration investigated the feasibility of using the Surveillance and Measurement System (SAMS) (innovative technology) to make in situ isotopic radiation measurements in paint and soil. Sample collection and on-site laboratory analysis (baseline technology) is currently being used on D and D sampling activities. Benefits expected from using the innovative technology include: Significant decrease in time to receive results on radiological samples; Decrease in cost associated with sample collection, preparation, analysis, and disposal; Equivalent data quality to laboratory analysis; and Fewer

Mahaffy, P. R.; Cabane, M.; Webster, C. R.

2008-01-01

The 2009 Mars Science Laboratory (MSL) with a substantially larger payload capability that any other Mars rover, to date, is designed to quantitatively assess a local region on Mars as a potential habitat for present or past life. Its goals are (1) to assess past or present biological potential of a target environment, (2) to characterize geology and geochemistry at the MSL landing site, and (3) to investigate planetary processes that influence habitability. The Sample Analysis at Mars (SAM) Suite, in its final stages of integration and test, enables a sensitive search for organic molecules and chemical and isotopic analysis of martian volatiles. MSL contact and remote surface and subsurface survey Instruments establish context for these measurements and facilitate sample identification and selection. The SAM instruments are a gas chromatograph (GC), a mass spectrometer (MS), and a tunable laser spectrometer (TLS). These together with supporting sample manipulation and gas processing devices are designed to analyze either the atmospheric composition or gases extracted from solid phase samples such as rocks and fines. For example, one of the core SAM experiment sequences heats a small powdered sample of a Mars rock or soil from ambient to -1300 K in a controlled manner while continuously monitoring evolved gases. This is followed by GCMS analysis of released organics. The general chemical survey is complemented by a specific search for molecular classes that may be relevant to life including atmospheric methane and its carbon isotope with the TLS and biomarkers with the GCMS.

To be ready for the computing-everywhere age to come, it is necessary to create environments in which the barrier-free utilization is ensured of various apparatuses of the daily routine, such as various bodily function substituting apparatuses capable of compensating for the degraded functions of disabled or aged individuals. Under the circumstances, a system for building man-machine interfaces in the home or the like is required, and fundamental technologies of architecture and information infrastructure have to be established on which the development of technologies for the field involved will proceed. Concerning the technologies already in existence in this field of research, a survey is conducted of the status of research and development of information interface techniques primarily at Stanford University, and a report is made thereon. Also reported is the information obtained at Technology and Persons with Disabilities Conference 1999. The result of a survey of the trend of research and development of the smart house under the TIDE (Technology Initiative for Disabled and Elderly People) project and the result of a survey of an information standardization project for equipment control in Europe are reported, and the result of a survey of the approach of Kyoto's welfare apparatus distributors to the development of equipment is made known.

Among the experiments which explore the martian soil aboard the Curiosity Rover, SAM experiment is mainly dedicated to the search for indigenous organic compounds. To reach its goals SAM can operate in different analysis modes: Pyrolysis-GC-MS and Pyrolysis-MS (EGA). In addition SAM includes wet chemistry experiments [1] to supports extraction of polar organic compounds from solid samples that improves their detection either by increasing the release of chemical species from solid sample matrices, or by changing their chemical structure to make compounds more amenable to gas chromatography mass spectrometry (GCMS). The two wet chemistry experimental capabilities of SAM provide alternatives to the nominal inert-thermal desorption/pyrolysis analytical protocol and are more aptly suited for polar components: MTBSTFA derivatization [2-3] and TMAH thermochemolysis [4-5]. Here we focus on the MTBSTFA derivatization experiment. In order to build a support used to help the interpretation of SAM results, we have investigated the artifacts and backgrounds sources generated by the all analysis process: Solid sample were heated up to approximately 840°C at a rate of 35°C/min under He flow. For GC analyses, the majority of the gas released was trapped on a hydrocarbon trap (Tenax®) over a specific temperature range. Adsorbed volatiles on the GC injection trap (IT) were then released into the GC column (CLP-MXT 30m x 0.25mm x 0.25μm) by rapidly heating the IT to 300°C. Then, in order better understand the part of compounds detected coming from internal reaction we have performed several lab experiments to mimic the SAM device: Among the sources of artifact, we test: (1) the thermal stability and the organic material released during the degradation of Tenax® and carbosieve, (2) the impact of MTBSTFA and a mixture of DMF and MTBSTFA on the adsorbent, (3) the reaction between the different adsorbents (Tenax® and Carbosieve) and calcium perchlorate and then (4) the sources

Fragrance materials are widely used in cosmetics and other consumer products. The Research Institute for Fragrance Materials (RIFM) evaluates the safety of these ingredients and skin absorption is an important parameter in refining systemic exposure. Currently, RIFM's safety assessment process assumes 100% skin absorption when experimental data are lacking. This 100% absorption default is not supportable and alternate default values were proposed. This study aims to develop and validate a practical skin absorption model (SAM) specific for fragrance material. It estimates skin absorption based on the methodology proposed by Kroes et al. SAM uses three default absorption values based on the maximum flux (J(max)) - namely, 10%, 40%, and 80%. J(max) may be calculated by using QSAR models that determine octanol/water partition coefficient (K(ow)), water solubility (S) and permeability coefficient (K(p)). Each of these QSAR models was refined and a semi-quantitative mechanistic model workflow is presented. SAM was validated with a large fragrance-focused data set containing 131 materials. All resulted in predicted values fitting the three-tiered absorption scenario based on Jmax ranges. This conservative SAM may be applied when fragrance material lack skin absorption data.

To implicate the private sector in funding: The Kyoto mechanisms and SUMO policies

International Nuclear Information System (INIS)

Leguet, Benoit; Morel, Romain

2015-01-01

Internationally set objectives in the fight against climate change cannot be reached without funding from the private sector. Public money, a scarce resource, must be used as best possible, in particular when it has a leverage effect on private funding. In this respect, feedback from the Kyoto Protocol's clean development mechanism is of interest. On the eve of the 2015 Paris Climate Conference, we must ramp up the mobilization of private resources. Smart unconventional monetary (SUMO) policies could help us toward this goal. Several countries have adopted such policies to cope with macro-economic circumstances or systemic risks. Is the destabilization of the climate not a risk of this sort?

Political realities and economic realities towards a Kyoto protocol

Bourdaire, J.M.

1997-01-01

The current climate change commitments and the negotiating positions of Annex I countries were discussed. It was pointed out that the energy sector is not homogeneous and therefore, climate change should focus on the areas all over the world which are most sensitive to a carbon value. It was also noted that while the present time is ripe for action on climate change, actions should not take place at any cost. A scenario based on the three principal functions of energy, i.e. to supply mobility, electricity and heat was proposed. It was claimed that this proposal had the potential to bridge the gap between the political reality of Kyoto and the economic realities of the energy sector. The essence of the proposal centred around the concept of 'carbon value'. The effect of establishing carbon values for each of the different energy services worldwide, was discussed. Various mechanisms for establishing carbon values, such as emission trading, joint implementation with non-Annex I parties, penalties for non-compliance, mitigation efforts in least-cost options, were also reviewed

Swedish Industry and Kyoto. An Assessment of the Effects of the European CO2 Emission Permit Trading System

International Nuclear Information System (INIS)

Braennlund, Runar; Lundgren, Tommy

2005-01-01

We assess the effects on Swedish industry input and output demands of different climate policy scenarios connected to energy policy induced by the Kyoto protocol. A unique data set containing firm level data on outputs and inputs during the years 1991-2001 is used to estimate a factor demand model, which is then simulated for different policy scenarios. Sector specific estimation suggests that the proposed quadratic profit function specification exhibit properties and robustness that are consistent with economic theory; that is, all own-price elasticities are negative and all output elasticities are positive. Furthermore, the elasticities show that the input demands are, in most cases, relatively inelastic. Simulation of the model for 6 different policy scenarios reveal that the effects on Swedish base industry of a EU level permit trade system is dependent on (i) removal or no removal of current CO 2 tax, (ii) the established price of permits, and (iii) what will happen to the electricity price. Our analysis show that changes in electricity price may be more important than the price of permits for some sectors

Implementing the Kyoto protocol in Europe: Interactions between international and Community controls

International Nuclear Information System (INIS)

Tabau, Anne-Sophie

2011-07-01

This bibliographical note presents a book which discusses the coexistence of the Kyoto protocol and of a regional regime within the European Union for the actual application of rules requiring mechanisms of control. The international regime implements a continuous monitoring which combines conventional techniques and more intrusive procedures. The European Community introduced a non-contentious mechanism with a large and strong law basis and sanction ability. The author assesses the ability of the monitoring system as a whole to ensure the very credibility of the Protocol. She also assesses the reliability of international and community economic tools which aim at reducing greenhouse gas emissions at a minimum cost. She also discusses the desirable evolutions of the regime of struggle against climate changes

A database of research publication was constructed for the purpose of grasping all of the research activities at the Research Reactor Institute, Kyoto University. The database named KURRIP collects all of the research publications of the Institute by not only its own staff but also visiting scientists. The publications are in the form of original papers, review papers, papers in proceedings, short notes and letters, synopses over 3 pages presented orally at scientific meeting, books and doctoral theses. At present, the KURRIP database contains the information on 6,210 items which have been published for 30 years since the Institute was established as an interuniversity research institute for joint use of a research reactor and other related large facilities in 1963. By utilizing the KURRIP database, the analyses have been done: (1) affiliation of the authors, (2) kind of publications, (3) classification of publishers, (4) research fields, and (5) experimental facilities. The KURRIP database is now stored in the Data Processing Center of Kyoto University and can be utilized through a computer center at one of the main national universities in Japan. (author)

PDS4 vs PDS3 - A Comparison of PDS Data for Two Mars Rovers - Existing Mars Curiosity Mission Mass Spectrometer (SAM) PDS3 Data vs Future ExoMars Rover Mass Spectrometer (MOMA) PDS4 Data

The Sample Analysis at Mars (SAM) instrument is a suite of instruments on Mars aboard the Mars Science Laboratory rover. Centered on a mass spectrometer, SAM delivers its data to the PDS Atmosphere's node in PDS3 format. Over five years on Mars the process of operating SAM has evolved and extended significantly from the plan in place at the time the PDS3 delivery specification was written. For instance, SAM commonly receives double or even triple sample aliquots from the rover's drill. SAM also stores samples in spare cups for long periods of time for future analysis. These unanticipated operational changes mean that the PDS data deliveries are absent some valuable metadata without which the data can be confusing. The Mars Organic Molecule Analyzer (MOMA) instrument is another suite of instruments centered on a mass spectrometer bound for Mars. MOMA is part of the European ExoMars rover mission schedule to arrive on Mars in 2021. While SAM and MOMA differ in some important scientific ways - MOMA uses an linear ion trap compared to the SAM quadropole mass spectrometer and MOMA has a laser desorption experiment that SAM lacks - the data content from the PDS point of view is comparable. Both instruments produce data containing mass spectra acquired from solid samples collected on the surface of Mars. The MOMA PDS delivery will make use of PDS4 improvements to provide a metadata context to the data. The MOMA PDS4 specification makes few assumptions of the operational processes. Instead it provides a means for the MOMA operators to provide the important contextual metadata that was unanticipated during specification development. Further, the software tools being developed for instrument operators will provide a means for the operators to add this crucial metadata at the time it is best know - during operations.

Political and technical issues of coal fire extinction in the Kyoto framework

Science.gov (United States)

Meyer, U.; Chen-Brauchler, D.; Rüter, H.; Fischer, C.; Bing, K.

It is a highly desirable effort to extinguish as much coal fires as possible in short time to prevent large losses of energy resources and to minimise CO2 and other exhaust gas releases from such sources. Unfortunately, extinguishing coal fires needs massive financial investments, skilled man power, suited technology and a long time. Even mid to small scale coal fires need several months of extinguishing measures and of monitoring time after extinction resulting in expenditures of a minimum of several hundred thousand Euros. Large companies might be willing to spend money for coal fire extinction measures but smaller holdings or regional governments might not have the monetary resources for it. Since there is no law in China that demands coal fire extinction, measures under the Kyoto framework may be applied to sell CO2 certificates for prevented emissions from extinguished coal fires and thus used as a financial stimulus for coal fire extinction activities. The set-up for methodologies and project designs is especially complex for coal fire extinction measures and thus for necessary exploration, evaluation and monitoring using geophysical and remote sensing methods. A brief overview of most important formal and technical aspects is given to outline the conditions for a potentially successful CDM application on coal fires based on geophysical observations and numerical modelling.

The expression, purification and crystallization of nosiheptide-resistance methyltransferase (NSR) from Streptomyces actuosus is described. Nosiheptide-resistance methyltransferase (NSR) methylates 23S rRNA at the nucleotide adenosine 1067 in Escherichia coli and thus contributes to resistance against nosiheptide, a sulfur-containing peptide antibiotic. Here, the expression, purification and crystallization of NSR from Streptomyces actuosus are reported. Diffracting crystals were grown by the hanging-drop vapour-diffusion method in reservoir solution consisting of 0.35 M ammonium chloride, 24%(w/v) PEG 3350, 0.1 M MES pH 5.7 at 293 K. Native data have been collected from the apo enzyme and a SAM complex, as well as apo SeMet SAD data. The diffraction patterns of the apo form of NSR, of NSR complexed with SAM and of SeMet-labelled NSR crystals extended to 1.90, 1.95 and 2.25 Å resolution, respectively, using synchrotron radiation. All crystals belonged to space group P2 1 , with approximate unit-cell parameters a = 64.6, b = 69.6, c = 64.9 Å, β = 117.8°
