    The Food and Drug Administration (FDA) put in place a general ban on the use of chlorofluorocarbons for the products it regulates (medical devices, drugs, and foods) in 1978, exempting those products where chlorofluorocarbon use was determined to be essential for the public health. In the intervening years, as the international commitment to a full transition away from all chlorofluorocarbon use took shape under the Montreal Protocol, the FDA has worked with industry to facilitate the development and testing of alternative technologies and products for inhalation drug products. As these alternative products begin to move from testing through the approval process and into marketing, the FDA is working collaboratively with the Environmental Protection Agency, other governmental agencies, and nongovernmental stakeholders to develop a transition policy for the United States. The transition policy for metered dose inhalers must be one that achieves the dual aims of first protecting the patients who rely on these vital medical products, while also achieving the public health need of protecting the ozone layer. As a part of developing such a transition strategy, the FDA published an advance notice of proposed rulemaking (ANPRM) in March 1997. The ANPRM proposed mechanisms by which the FDA could determine when chlorofluorocarbon use in a drug product could no longer be considered essential. The ANPRM resulted in a large amount of valuable public debate and input. The FDA is now working to incorporate the knowledge gained from these public comments as it continues the rule-making process.

    A comparison is made of the radiative (greenhouse) forcing of the climate system due to changes of atmospheric chlorofluorocarbons and other trace gases. It is found that CFCs, defined to include chlorofluorocarbons, chlorocarbons, and fluorocarbons, now provide about one-quater of current annual increases in anthropogenic greenhouse climate forcing. If the growth rates of CFC production in the early 1970s had continued to the present, current annual growth of climate forcing due to CFCs would exceed that due to CO2.

    The infrared bands of chlorofluorocarbons and chlorocarbons enhance the atmospheric greenhouse effect. This enhancement may lead to an appreciable increase in the global surface temperature if the atmospheric concentrations of these compounds reach values of the order of 2 parts per billion.

    Chlorofluorocarbons have been among the most useful chemical compounds ever developed. However, after more than forty years of a continuously increasing rate of worldwide use in the industrial and domestic sectors, unequivocal evidence has indicated that, if released into Earth's atmosphere, they are amongst the most devastating of pollutants that could threaten the quality of life for future generations. Thus it is not surprising that, for nearly two decades, this dichotomy of interests has been a prominent issue. This report presents the scientific evidence available concerning the impacts of chlorofluorocarbons on the ambient environment. Regional, national and international policies adopted to try to curb their emissions into the atmosphere are summarised. Economic and social consequences of these policies are discussed, together with some of the available and recommended technological solutions to the environmental problem. It is believed that agreements reached internationally to date are insufficient to ensure the adequate protection of the environment. Even an immediate total ban on the production and use of such chemical compounds would not lead to a reversal of the environmental degradation for at least a century, due to the chlorofluorocarbons already in the atmosphere.

    The destruction of ozone-depleting substances, in particular chlorofluorocarbons and halons, in the PLASCON plasma process is investigated. In particular, the use of oxygen and steam as oxidising gases is compared. Measurements of the exhaust gas composition are compared with the results Of calculations performed using a comprehensive chemical kinetic scheme. It is found that significant interconversion of ozone-depleting substances occurs, particularly for chloro-fluorocarbon destruction Steam is found to be a superior oxidising gas to oxygen, with greatly reduced levels of ozone-depleting substances and CF{sub 4} in the exhaust gas, particularly if the steam is input at close to or greater than stoichiometric levels.

    Full Text Available Ozone depletion by chlorofluorocarbons (CFCs was first proposed by Molina and Rowland in their 1974 Nature paper. Since that time, the scientific connection between ozone losses and CFCs and other ozone depleting substances (ODSs has been firmly established with laboratory measurements, atmospheric observations, and modeling studies. This science research led to the implementation of international agreements that largely stopped the production of ODSs. In this study we use a fully-coupled radiation-chemical-dynamical model to simulate a future world where ODSs were never regulated and ODS production grew at an annual rate of 3%. In this "world avoided" simulation, 17% of the globally-averaged column ozone is destroyed by 2020, and 67% is destroyed by 2065 in comparison to 1980. Large ozone depletions in the polar region become year-round rather than just seasonal as is currently observed in the Antarctic ozone hole. Very large temperature decreases are observed in response to circulation changes and decreased shortwave radiation absorption by ozone. Ozone levels in the tropical lower stratosphere remain constant until about 2053 and then collapse to near zero by 2058 as a result of heterogeneous chemical processes (as currently observed in the Antarctic ozone hole. The tropical cooling that triggers the ozone collapse is caused by an increase of the tropical upwelling. In response to ozone changes, ultraviolet radiation increases, more than doubling the erythemal radiation in the northern summer midlatitudes by 2060.

    Highlights: • Chlorofluorocarbons and halons are potent ozone depleting substances and greenhouse gases. • No provisions in the Montreal or in Kyoto Protocol to destroy stockpiles of concentrated CFCs. • The UNEP recommends 11 technologies for destruction of concentrated CFCs. • No studies have up to now investigated the potential of using cement kilns in developing countries. • The test demonstrated that the local Indian cement kiln was able to destroy high feeding rates of several concentrated CFC-gases effectively. - Abstract: The Montreal Protocol aims to protect the stratospheric ozone layer by phasing out production of substances that contribute to ozone depletion, currently covering over 200 individual substances. As most of these compounds are synthetic greenhouse gases, there is an opportunity to curb both ozone depletion and climate change simultaneously by requiring Parties of both the Montreal and the Kyoto Protocol to destroy their existing stocks of concentrated chlorofluorocarbons (CFCs). Many emerging countries still possess stocks which need to be destroyed in an environmentally sound manner but costs may be prohibitive. The UNEP Technology and Economic Assessment Panel identified in 2002 eleven destruction technologies which meet the criteria for environmentally sound destruction of chlorofluorocarbons. Cement kilns were among these, but no study has been reported in scientific literature assessing its destruction performance under real developing country conditions up to now. In contrast to incinerators and other treatment techniques, high temperature cement kilns are already in place in virtually every country and can, if found technical feasible, be retrofitted and adapted cost-efficiently to destroy chemicals like CFCs. India has the second largest cement industry in the world and several hazardous waste categories have been tested successfully in recent years. The objective of this study was to carry out the first full scale

    The NOAA Chlorofluorocarbon (CFC) Tracer Program at PMEL has been measuring the growing burden of these anthropogenic gases in the thermocline waters of the Pacific Ocean since 1980. The central goals of the NOAA CFC Tracer Program are to document the transient invasion of the CFC tracers into the Pacific Ocean, by means of repeat occupations of key hydrographic sections at 5-year intervals, and to interpret these changing distributions in terms of coupled ocean-atmosphere models. Studies are underway to use the CFC observations in model-validation studies, and to help develop predictive capabilities on the decade-to-century timescale. The report includes measurements of trichlorofluoromethane (CFC-11) and dichlorodifluoromethane (CFC-12) dissolved in seawater samples collected in the Pacific Ocean by the NOAA CFC Tracer Program on six cruises during the period of 1986-1989. Measurements of depth, pressure, salinity, temperature, and dissolved oxygen are included with the CFC data. Measurements of CFC-11 and CFC-12 in air samples collected along the cruise tracks are also included in the report. Data from the report are also available from the authors in digital format

    1997-01-01

    Three gaseous diffusion plants (GDPs) for enriching uranium maintain a large inventory of chlorofluorocarbon-114 (CFC-114) as a coolant. To address the continued use of CFC-114, an ozone-depleting substance, the US Department of Energy (DOE) considered introducing perfluorocarbons (PFCs) by the end of 1995. These PFCs would not contribute to stratospheric ozone depletion but would be larger contributors to global warming than would CFC-114. The paper reports the results of an assessment of the global impacts of four alternatives for modifying GDP coolant system operations over a three-year period beginning in 1996. The overall contribution of GDP coolant releases to impacts on ozone depletion and global warming were quantified by parameters referred to as ozone-depletion impact and global-warming impact. The analysis showed that these parameters could be used as surrogates for predicting global impacts to all resources and could provide a framework for assessing environmental impacts of a permanent coolant replacement, eliminating the need for subsequent resource-specific analyses

    Antarctic Bottom Water (AABW) is the coldest, densest, most prolific water mass in the global ocean. AABW forms at several distinct regions along the Antarctic coast and feeds into the bottom limb of the meridional overturning circulation, filling most of the global deep ocean. AABW has warmed, freshened, and declined in volume around the globe in recent decades, which has implications for the global heat and sea level rise budgets. Over the past three decades, the use of tracers, especially time-varying tracers such as chlorofluorocarbons, has been essential to our understanding of the formation, circulation, and variability of AABW. Here, we review three decades of temperature, salinity, and tracer data and analysis that have led to our current knowledge of AABW and how the southern component of deep-ocean ventilation is changing with time.

  17. Age dating ground water by use of chlorofluorocarbons (CCl3F and CCl2F2), and distribution of chlorofluorocarbons in the unsaturated zone, Snake River Plain aquifer, Idaho National Engineering Laboratory, Idaho

    1993-04-01

    Detectable concentrations of chlorofluorocarbons (CFC's) were observed in ground water and unsaturated-zone air at the Idaho National Engineering Laboratory (INEL) and vicinity. The recharge ages of waters were determined to be from 4 to more than 50 years on the basis of CFC concentrations and other environmental data; most ground waters have ages of 14 to 30 years. These results indicate that young ground water was added at various locations to the older regional ground water (greater than 50 years) within and outside the INEL boundaries. The wells drilled into the Snake River Plain aquifer at INEL sampled mainly this local recharge. The Big Lost River, Birch Creek, the Little Lost River, and the Mud Lake-Terreton area appear to be major sources of recharge of the Snake River Plain aquifer at INEL. An average recharge temperature of 9.7±1.3 degrees C (degrees Celsius) was calculated from dissolved nitrogen and argon concentrations in the ground waters, a temperature that is similar to the mean annual soil temperature of 9 degrees C measured at INEL. This similarity indicates that the aquifer was recharged at INEL and not at higher elevations that would have cooler soil temperatures than INEL. Soil-gas concentrations at Test Area North (TAN) are explained by diffusion theory

    This raster data set delineates the predicted probability of unmixed young groundwater (defined using chlorofluorocarbon-11 concentrations and tritium activities) in groundwater in the Eagle River watershed valley-fill aquifer, Eagle County, North-Central Colorado, 2006-2007. This data set was developed by a cooperative project between the U.S. Geological Survey, Eagle County, the Eagle River Water and Sanitation District, the Town of Eagle, the Town of Gypsum, and the Upper Eagle Regional Water Authority. This project was designed to evaluate potential land-development effects on groundwater and surface-water resources so that informed land-use and water management decisions can be made. This groundwater probability map and its associated probability maps were developed as follows: (1) A point data set of wells with groundwater quality and groundwater age data was overlaid with thematic layers of anthropogenic (related to human activities) and hydrogeologic data by using a geographic information system to assign each well values for depth to groundwater, distance to major streams and canals, distance to gypsum beds, precipitation, soils, and well depth. These data then were downloaded to a statistical software package for analysis by logistic regression. (2) Statistical models predicting the probability of elevated nitrate concentrations, the probability of unmixed young water (using chlorofluorocarbon-11 concentrations and tritium activities), and the probability of elevated volatile organic compound concentrations were developed using logistic regression techniques. (3) The statistical models were entered into a GIS and the probability map was constructed.

    International Nuclear Information System (INIS)

    1991-06-01

    The impetus for minimization or elimination of chlorofluorocarbons (CFCs) comes from the growing body of knowledge concerning depletion of the stratospheric ozone layer and formation of polar ozone 'holes'. The workshop concentrated on solvent usage, which constitutes some 12% of CFCs contribution to ozone depletion and is estimated by the U.S. Environmental Protection Agency (EPA) at a sales dollar volume of $145 million per year for the United States alone. There is widespread solvent use in the electronics, automotive, defense, and spacecraft industries, as well as by a myriad of smaller fabricators and for consumer products. Seventeen major corporations in collaboration with the EPA, have formed the Industry Cooperative for Ozone Layer Protection (ICOLP). Two meetings were held prior to the workshop. The first included presentations by representatives from the ICOLP member companies on the pertinent activities of their respective organizations. The objective of this meeting was to brief the steering committee on the needs, limitations, problems, and successes in the development of alternatives to CFCs. Much of the background material presented in the workshop report was compiled during this first meeting. The objectives of the second meeting of the steering committee were to plan the agenda for the workshop and to identify the industry representatives to be invited

    The recombinant bacterium Pseudomonas putida G786(pHG-2) metabolizes pentachloroethane to glyoxylate and carbon dioxide, using cytochrome P-450CAM and toluene dioxygenase to catalyze consecutive reductive and oxidative dehalogenation reactions (L.P. Wackett, M.J. Sadowsky, L.N. Newman, H.-G. Hur, and S. Li, Nature [London] 368:627-629, 1994). The present study investigated metabolism of brominated and chlorofluorocarbon compounds by the recombinant strain. Under anaerobic conditions, P. putida G786(pHG-2) reduced 1,1,2,2-tetrabromoethane, 1,2-dibromo-1,2-dichloroethane, and 1,1,1,2-tetrachloro-2,2-difluoroethane to products bearing fewer halogen substituents. Under aerobic conditions, P. putida G786(pHG-2) oxidized cis- and trans-1,2-dibromoethenes, 1,1-dichloro-2,2-difluoroethene, and 1,2-dichloro-1-fluoroethene. Several compounds were metabolized by sequential reductive and oxidative reactions via the constructed metabolic pathway. For example, 1,1,2,2-tetrabromoethane was reduced by cytochrome P-450CAM to 1,2-dibromoethenes, which were subsequently oxidized by toluene dioxygenase. The same pathway metabolized 1,1,1,2-tetrachloro-2,2-difluoroethane to oxalic acid as one of the final products. The results obtained in this study indicate that P. putida G786(pHG-2) metabolizes polyfluorinated, chlorinated, and brominated compounds and further demonstrates the value of using a knowledge of catabolic enzymes and recombinant DNA technology to construct useful metabolic pathways.

    2003-01-01

    This article discusses new Swiss regulations on the use of synthetic materials that posses a considerable greenhouse-warming potential. Synthetic materials such as hydro-chlorofluorocarbons HCFCs, perfluoride-hydrocarbons and sulphur hexafluoride have, in recent years, replaced chlorofluorocarbons CFCs, which were banned on account of their ozone depletion characteristics. The use of these persistent substances is now being limited to applications where more environment-friendly alternatives are not available. The measures decreed in the legislation, which include a general ban on HCFCs as of 2004 and a ban on the export of installations and equipment that use ozone-depleting refrigerants are described. Details on the legislation's effects on the Swiss refrigeration industry are listed and discussed

    2010-09-01

    In the framework of the investigation of enrichment processes of nitrate in groundwater of the Kalahari of Botswana near Serowe, recharge processes were investigated. The thick unsaturated zone extending to up to 100 m of mostly unconsolidated sediments and very low recharge rates pose a serious challenge to study solute transport related to infiltration and recharge processes, as this extends past the conventional depths of soil scientific investigations and is difficult to describe using evidence from the groundwater due to the limitations imposed by available tracers. To determine the link between nitrate in the vadose zone and in the uppermost groundwater, sediment from the vadose zone was sampled up to a depth of 15-20 m (in one case also to 65 m) on several sites with natural vegetation in the research area. Among other parameters, sediment and water were analysed to determine chloride and nitrate concentration depth profiles. Using the chloride mass balance method, an estimation of groundwater infiltration rates produced values of 0.2-4 mm a(-1). The uncertainty of these values is, however, high. Because of the extreme thickness of the vadose zone, the travel time in the unsaturated zone might reach extreme values of up to 500 years and more. For investigations using groundwater, we applied the chlorofluorocarbons CFC-113, CFC-12, sulphur hexafluoride (SF(6)) and tritium to identify potential recharge, and found indications for some advective transport of the CFCs and SF(6), which we accounted for as constituting potential active localised recharge. In our contribution, we show the potential and limitations of the applied methods to determine groundwater recharge and coupled solute transport in semi-arid settings, and compare travel time ranges derived from soil science and groundwater investigations.

    1998-01-01

    Stringent regulations to reduce the use of chlorofluorocarbons (CFC) and halogenated chlorofluorocarbons (HCFC) have been set into force by many European countries. A ban for new plants containing HCFCs in 2005 and a total ban of HCFCs in 2020 are discussed within the European Community. Siemens-KWU and Sulzer Escher Wyss have developed a well-proofed procedure to solve the CFC problem for existing refrigeration systems in nuclear power plants. The new refrigerants are fluorinated hydrocarbons and for the centrifugal water chiller R134a is best suited. Prior to the market introduction toxicity, short and long term health effects, inflammability and stability of R134a have been investigated. The mechanical examination included wear, corrosion, lubrication and resistance to decomposition. A well-proven procedure was established which ensures the owner of the plant and the supplier best results

    An assessment of the state of the art in refrigeration and insulation technologies is carried out to evaluate the potential for efficient substitutes for CFCs and HCFCs to facilitate the transition to a CFC-free environment. Opportunities for improved efficiency in domestic refrigeration, building chillers, commercial refrigeration and industrial refrigeration are evaluated. Needs for alternate refrigerants, improved components, and/or alternate cycles are identified. A summary of on-going research is presented in each area, and the potential roles of industry and government are considered. The most promising approaches for refrigeration technology fall into these categories: (1) improved vapor compressor cycles with alternate fluids, (2) Stirling cycle development and (3) advances in absorption technology. A summary of on-going research into advanced insulation, focused on vacuum-based insulation technology refrigeration is developed. Insulation applications considered include appliances, transport refrigeration, and buildings. Specific recommendations for a long-term R&D agenda are presented. The potential benefits, research, general approach, and probability of success are addressed.

    Selected researchers from 21 countries were queried through questionnaires about their current and planned research activities. The results of the survey show that the majority of research being conducted by the respondents is devoted to investigating the hydrogenated fluorocarbon HFC-134a as a replacement for CFC-12 in refrigeration applications. The main issue with this alternative is identifying compatible lubricants that do not reduce its effectiveness.

    This report summarizes international efforts to protect stratospheric ozone. Also included in this report is a discussion of activities in other countries to meet restrictions in the production and use of ozone-depleting substances. Finally, there is a brief presentation of trade and international competitiveness issues relating to the transition to alternatives for the regulated chlorofluorocarbons (CFCs) and halons. The stratosphere knows no international borders. Just as the impact of reduced stratospheric ozone will be felt internationally, so protection of the ozone layer is properly an international effort. Unilateral action, even by a country that produces and used large quantities of ozone-depleting substances, will not remedy the problem of ozone depletion if other countries do not follow suit. 32 refs., 7 tabs.

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

    Based on observations of the chlorofluorocarbons CFC-13 (chlorotrifluoromethane), ΣCFC-114 (combined measurement of both isomers of dichlorotetrafluoroethane), and CFC-115 (chloropentafluoroethane) in atmospheric and firn samples, we reconstruct records of their tropospheric histories spanning nearly 8 decades. These compounds were measured in polar firn air samples, in ambient air archived in canisters, and in situ at the AGAGE (Advanced Global Atmospheric Gases Experiment) network and affiliated sites. Global emissions to the atmosphere are derived from these observations using an inversion based on a 12-box atmospheric transport model. For CFC-13, we provide the first comprehensive global analysis. This compound increased monotonically from its first appearance in the atmosphere in the late 1950s to a mean global abundance of 3.18 ppt (dry-air mole fraction in parts per trillion, pmol mol-1) in 2016. Its growth rate has decreased since the mid-1980s but has remained at a surprisingly high mean level of 0.02 ppt yr-1 since 2000, resulting in a continuing growth of CFC-13 in the atmosphere. ΣCFC-114 increased from its appearance in the 1950s to a maximum of 16.6 ppt in the early 2000s and has since slightly declined to 16.3 ppt in 2016. CFC-115 increased monotonically from its first appearance in the 1960s and reached a global mean mole fraction of 8.49 ppt in 2016. Growth rates of all three compounds over the past years are significantly larger than would be expected from zero emissions. Under the assumption of unchanging lifetimes and atmospheric transport patterns, we derive global emissions from our measurements, which have remained unexpectedly high in recent years: mean yearly emissions for the last decade (2007-2016) of CFC-13 are at 0.48 ± 0.15 kt yr-1 (> 15 % of past peak emissions), of ΣCFC-114 at 1.90 ± 0.84 kt yr-1 (˜ 10 % of peak emissions), and of CFC-115 at 0.80 ± 0.50 kt yr-1 (> 5 % of peak emissions).

    A study was done on dechlorination of 1,1,2-trichloro-1,2,2-trifluoroethane (CFC113) in neutral and alkaline alcohol solutions by means of γ-irradiation. The dechlorination yield (G (Cl - )) was found to depend on the kind of alcohol used as solvents and the presence of hydroxide ion. The order of G (Cl - ) value in alkaline solution was isopropyl alcohol>> ethyl alcohol > methyl alcohol. It was suggested that the high yield obtained in alkaline isopropyl alcohol solution is explained by a chain process in dechlorination reaction. In case of alkaline isopropyl alcohol solution, CFC113 was dechlorinated to lower chlorinated ethane, and 1,1-dichloro-1,2,2-trifluoroetane was a main product. We have discussed on the chain dechlorination mechanism in alkaline isopropyl alcohol solution. (author)

    The distribution of 3 He across the Southern Ocean is depicted on the basis of a meridional section between Antarctica and South Africa measured during the INDIGO-3 survey (1988). A core of δ 3 He values above 10% is observed south of the Polar Front, associated with very low CFC concentrations. This 3 He enriched layer is documented from the GEOSECS and INDIGO 3 He data in the Southern Ocean. It is found at a density level around θ σ =27.8 in all the waters close to Antarctica (i.e. south of 50 degS). Its zonal distribution suggests that it is likely that it originates from the central/eastern Pacific. Hence, it provides an indication of the deep Pacific waters in the Antarctic Circumpolar Current, which are not easily detectable from the standard hydrographic parameters.

  11. Choosing to regulate: does choice enhance craving regulation?

    2018-01-01

    Abstract Goal-directed behavior and lifelong well-being often depend on the ability to control appetitive motivations, such as cravings. Cognitive reappraisal is an effective way to modulate emotional states, including cravings, but is often studied under explicit instruction to regulate. Despite the strong prediction from Self-Determination Theory that choice should enhance task engagement and regulation success, little is known empirically about whether and how regulation is different when participants choose (vs are told) to exert control. To investigate how choice affects neural activity and regulation success, participants reappraised their responses to images of personally-craved foods while undergoing functional neuroimaging. Participants were either instructed to view or reappraise (‘no-choice’) or chose freely to view or reappraise (‘yes-choice’). Choice increased activity in the frontoparietal control network. We expected this activity would be associated with increased task engagement, resulting in better regulation success. However, contrary to this prediction, choice slightly reduced regulation success. Follow-up multivariate functional neuroimaging analyses indicated that choice likely disrupted allocation of limited cognitive resources during reappraisal. While unexpected, these results highlight the importance of studying upstream processes such as regulation choice, as they may affect the ability to regulate cravings and other emotional states.

    The tumor suppressor protein p53 plays important roles in DNA damage repair, cell cycle arrest and apoptosis. Due to its critical functions, the level of p53 is tightly regulated by a negative feedback mechanism to increase its tolerance towards fluctuations and disturbances. Interestingly, the p53 level is controlled by post-translational regulation rather than transcriptional regulation in this feedback mechanism. We analyzed the dynamics of this feedback to understand whether post-translational regulation provides any advantages over transcriptional regulation in regard to disturbance rejection. When a disturbance happens, even though negative feedback reduces the steady-state error, it can cause a system to become less stable and transiently overshoots, which may erroneously trigger downstream reactions. Therefore, the system needs to balance the trade-off between steady-state and transient errors. Feedback control and adaptive estimation theories revealed that post-translational regulation achieves a better trade-off than transcriptional regulation, contributing to a more steady level of p53 under the influence of noise and disturbances. Furthermore, post-translational regulation enables cells to respond more promptly to stress conditions with consistent amplitude. However, for better disturbance rejection, the p53- Mdm2 negative feedback has to pay a price of higher stochastic noise. Our analyses suggest that the p53-Mdm2 feedback favors regulatory mechanisms that provide the optimal trade-offs for dynamic control.

    Derwent, R. G.; Simmonds, P. G.; Greally, B. R.; O'doherty, S.; McCulloch, A.; Manning, A.; Reimann, S.; Folini, D.; Vollmer, M. K.

    The mixing ratios of HCFC-141b (1,1-dichlorofluoroethane) and HCFC-142b (1-chloro-1,1-difluoroethane) have been rising steadily in baseline air at Mace Head, Ireland over the 10-year period from 1994 to 2004. These HCFCs are widely used replacements for the chlorofluorocarbons phased out under the Montreal Protocol and its subsequent amendments. Analysis of the HCFC content of regionally-polluted air arriving at Mace Head from the European continent shows that European emissions reached a peak during 2000-2001 and have declined subsequently, following the phase-out in their usage. European emissions of HCFC-141b have been further constrained by observations at the High-Alpine Jungfraujoch site. The reductions are consistent with the phase-out of HCFC production and use from the year 2001 onwards mandated by European regulations designed to exceed the requirements of the Montreal Protocol.

    More than any other environmental problem, global warming is the product of ordinary human activities. Industry will probably have to be regulated, but the public at large will also have to adjust. Ultimately, the problem is going to be solved by a lot of individual decisions. The question is how to change the individuals making those decisions. Americans can do much to reduce the use of fossil fuels and chlorofluorocarbons on their own. Even without any new legislation, people can adopt many of the energy-saving tactics that caught on temporarily after the last oil crisis. They can become informed consumers, buying products that don't deplete the ozone layer or contribute to emissions of greenhouse gases and trying to reduce pollution from their cars and homes. As voters, individuals can elect officials who take global warming seriously and put pressure on those in office to impose stronger efficiency standards

    1990-03-01

    Low density polymeric foam materials expanded with chlorofluorocarbon (CFC) blowing agents have found widespread use as highly efficient thermal insulation materials in the construction, refrigeration appliance and transportation industries. The advent of regulations which are reducing the production and consumption of the fully halogenated CFCs for environmental reasons has prompted the development of environmentally acceptable substitutes for the CFC blowing agents. This paper summarizes the physical properties and performance of the leading alternatives for CFC-11, which is used to expand rigid polyurethane and polyisocyanurate foams, and the leading alternatives for CFC-12 which is used to expand extruded polystyrene board foam. Although the alternatives, HCFC-123 and HCFC-14lb for CFC-11 and HCFC142b and HCFC-124 for CFC-12, are not perfect matches from the performance viewpoint, they represent the optimum choice given the constraints on environmental acceptability, toxicity, flammability and performance.

    The article reports on a challenge to the UK electricity regulator to defend his record by the Coalition for Fair Electricity Regulation (COFFER). The challenge centres on whether the obligation for the regional electric companies (REC) to purchase power from the cheapest source is being enforced. This is related to the wider issue of whether the REC's support of combined-cycle gas turbine (CCGT) is economic. COFFER considers that uneconomic gas-fired power plants are being allowed to displace economic coal-fired stations. Aspects discussed include the background to the dispute and the costs of CCGT and coal fired power generation. 1 fig., 1 tab.

    The 1987 Montreal Protocol regulating emissions of ozone depleting chlorofluorocarbons (CFCs) was motivated primarily by the harm to human health and ecosystems arising from increased exposure to ultraviolet-B (UV-B) radiation associated with depletion from the ozone layer. It is now known that the Montreal Protocol has reduced global warming since CFCs are greenhouse gases (GHGs). In this paper we show that the Montreal Protocol also significantly protects the Earth's hydroclimate, even though this was also not a motivating factor in the decision-making that led to the Protocol. General Circulation Model (GCM) results show that in the coming decade (2020-29), under the 'World Avoided' scenario of no regulations on CFC emissions, the subtropical dry zones would in general get drier, and the middle and high latitude regions wetter. This change is similar, in both pattern and magnitude, to that in the coming decade caused by projected increases in carbon dioxide concentrations. This implies that because of the Montreal Protocol, and the ozone depletion and global warming associated with CFCs thus avoided, the hydrological cycle changes in the coming decade will be significantly less than what they otherwise would have been.

    Results are presented from experimental studies of the destruction of chlorofluorocarbon (CF 2 Cl 2 ) molecules in a methane-oxygen (air) gas mixture whose combustion is initiated by a high-current slipping surface discharge. It is found that a three-component CH 4 + O 2 (air)+ CF 2 Cl 2 gas mixture (even with a considerable amount of the third component) demonstrates properties of explosive combustion involving chain reactions that are typical of two-component CH 4 + O 2 mixtures. Experiments show the high degree of destruction (almost complete decomposition) of chlorofluorocarbons contained in the mixture during one combustion event. The combustion dynamics is studied. It is shown that the combustion initiated by a slipping surface discharge has a number of characteristic features that make it impossible to identify the combustion dynamics with the formation of a combustion or detonation wave. The features of the effects observed can be related to intense UV radiation produced by a pulsed high-current surface discharge

    Policies designed to restrict marketing, access to, and public use of electronic cigarettes (e-cigarettes) are increasingly under debate in various jurisdictions in the US. Little is known about public perceptions of these policies and factors that predict their support or opposition. Using a sample of US adults from Amazon Mechanical Turk in May 2015, this paper identifies beliefs about the benefits and costs of regulating e-cigarettes and identifies which of these beliefs predict support for e-cigarette restricting policies. A higher proportion of respondents agreed with 8 different reasons to regulate e-cigarettes (48.5% to 83.3% agreement) versus 7 reasons not to regulate e-cigarettes (11.5% to 18.9%). The majority of participants agreed with 7 out of 8 reasons for regulation. When all reasons to regulate or not were included in a final multivariable model, beliefs about protecting people from secondhand vapor and protecting youth from trying e-cigarettes significantly predicted stronger support for e-cigarette restricting policies, whereas concern about government intrusion into individual choices was associated with reduced support. This research identifies key beliefs that may underlie public support or opposition to policies designed to regulate the marketing and use of e-cigarettes. Advocates on both sides of the issue may find this research valuable in developing strategic campaigns related to the issue. Specific beliefs of potential benefits and costs of e-cigarette regulation (protecting youth, preventing exposure to secondhand vapor, and government intrusion into individual choices) may be effectively deployed by policy makers or health advocates in communicating with the public.

    The humankind or anthropogenic influence on ozone primarily originated from the chlorofluorocarbons and halons (chlorine and bromine). Representatives from governments have met periodically over the years to establish international regulations starting with the Montreal Protocol in 1987, which greatly limited the release of these ozone-depleting substances (DDSs). Two global models have been used to investigate the impact of hypothetical reductions in future emissions of ODSs on total column ozone. The investigations primarily focused on chlorine- and bromine-containing gases, but some computations also included nitrous oxide (N2O). The Montreal Protocol with ODS controls have been so successful that further regulations of chlorine- and bromine-containing gases could have only a fraction of the impact that regulations already in force have had. if all anthropogenic ODS emissions were halted beginning in 2011, ozone is calculated to be higher by about 1-2% during the period 2030-2100 compared to a case of no additional ODS restrictions. Chlorine- and bromine-containing gases and nitrous oxide are also greenhouse gases and lead to warming of the troposphere. Elimination of N 20 emissions would result in a reduction of radiative forcing of 0.23 W/sq m in 2100 than presently computed and destruction of the CFC bank would produce a reduction in radiative forcing of 0.005 W/sq m in 2100. This paper provides a quantitative way to consider future regulations of the CFC bank and N 20 emissions

    1995-01-01

    CFC is chemically and thermally stable, and almost harmless to human body, therefore, it has been used widely for various industries, in particular as the heat media for air conditioners and the washing agent for semiconductors and printed circuit substrates. In 1974, it was pointed out that CFC causes the breakdown of ozone layer, and the ozone hole was found, consequently, it was decided to limit its use, and to prohibit the production of specific CFC. The development of the decomposition treatment technology for the CFC now in use, which is friendly to the global environment including mankind and ozone layer, is strongly desired. Recently, the authors have examined the decomposition treatment method for specific CFC solvents by irradiation, and obtained the interesting knowledge. For the experiment, the CFC 113 was used, and its chemical structure is shown. The experimental method is explained. As the results, the effect of hydroxide ions, the decomposition products such as CFC 123, and the presumption of the mechanism of the chain dechlorination reaction of CFC 113 are reported. The irradiation decomposition method was compared with various other methods, and the cost of treatment is high. The development for hereafter is mentioned. (K.I.)

    Some chlorofluorocarbons (CFCs) are well-adapted to coldness production by vapour compression and thus are widely used in the storage of agriculture-food products from the production to the domestic consumer but also in air-conditioning systems and heat pumps. Atmospheric impacts of the use of CFCs (`ozone hole`) led the international community to adopt remedial measures which aim to prohibit the production of CFCs. These constraints led the users of refrigerating fluids to use substitution fluids and to develop new techniques of energy recovery and heat/coldness production. This workshop takes stock of this situation and of the problems encountered by the various actors involved in the replacement of CFCs in thermodynamical systems: evolutions of regulation, point of view of refrigerating fluid producers and of compressors and heat exchangers manufacturers, research studies on substitution fluids, recovery of CFCs and other refrigerating fluids, revival in the use of natural fluids (like ammonia), and use of new thermodynamical systems like compression/absorption (water/ammonia) cycles.

    Leading edge companies throughout the world have embraced management systems to achieve optimal sustainable performance in the ever changing business environment of the 1990s. Given that the natural environment and environmental performance have become major issues affecting organizations, the need for integrating environmental management with all the other components of an organization`s overall management approach is now widely recognized. This paper is organized in five parts. The first explores recently released environmental standards, the interim environmental management systems (EMS) general guidelines standard AS/NZS ISO 14004 (Int) and identifies how this has dealt with the regulator/community/company interface. The second identifies company requirements for addressing environmental issues. The third, considers regulatory theory to identify current requirements for an effective regulatory system and how this can interface with a company`s EMS. These form the basis in the fourth section for identifying some opportunities which occur at the company/ regulator interface. The fifth and final section draws a number of conclusions about the current frontiers of environmental regulation. The coincidence of the requirements of a regulatory framework with the areas of interface between what is referred to in the draft International Standard for EMS as `Interested Parties`, the regulators and community, are identified.

    A peak regulation right concept and corresponding transaction mechanism for an electricity market was presented. The market was based on a power pool and independent system operator (ISO) model. Peak regulation right (PRR) was defined as a downward regulation capacity purchase option which allowed PRR owners to buy certain quantities of peak regulation capacity (PRC) at a specific price during a specified period from suppliers. The PRR owner also had the right to decide whether or not they would buy PRC from suppliers. It was the power pool's responsibility to provide competitive and fair peak regulation trading markets to participants. The introduction of PRR allowed for unit capacity regulation. The PRR and PRC were rated by the supplier, and transactions proceeded through a bidding process. PRR suppliers obtained profits by selling PRR and PRC, and obtained downward regulation fees regardless of whether purchases are made. It was concluded that the peak regulation mechanism reduced the total cost of the generating system and increased the social surplus. 6 refs., 1 tab., 3 figs

    The Title VI Stratospheric Ozone Protection Program of the Clean Air Act (CAA) requires promulgation of regulations to reduce and prevent damage to the earth's protective ozone layer. Regulations pursuant to Title VI of the CAA are promulgated in the Code of Federal Regulations (CFR) at Title 40 CFR, Part 822. The regulations include ambitious production phaseout schedules for ozone depleting substances (ODS) including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, carbon tetrachloride, and methyl chloroform under 40 CFR 82, Subpart A. The regulations also include requirements for recycling and emissions reduction during the servicing of refrigeration equipment and technician certification requirements under Subpart F; provisions for servicing of motor vehicle air conditioners under Subpart B; a ban on nonessential products containing Class 1 ODS under Subpart C; restrictions on Federal procurement of ODS under Subpart D; labeling of products using ODS under Subpart E; and the Significant New Alternatives Policy Program under Subpart G. This paper will provide details of initiatives undertaken at US Department of Energy (DOE) Oak Ridge Reservation (ORR) Facilities for implementation of requirements under the Title VI Stratospheric Ozone Protection Program. The Stratospheric Ozone Protection Plans include internal DOE requirements for: (1) maintenance of ODS inventories; (2) ODS procurement practices; (3) servicing of refrigeration and air conditioning equipment; (4) required equipment modifications or replacement; (5) technician certification training; (6) labeling of products containing ODS; (7) substitution of chlorinated solvents; and (8) replacement of halon fire protection systems.

    The troposphere is chemically complex. Many of the important species in the troposphere are short-lived, with lifetimes less than or of order of a month. Hence, the composition of the troposphere is regionally diverse, leading to regionally diverse chemical processes which control that composition. With the advent of three-dimensional models and regionally-specific estimates of emissions, however, it has become clear that human activity has perturbed the composition of even short-lived species over vast regions of the globe. The list of short-lived species of concern includes the reactive nitrogen oxides, reactive sulfur, ozone, nonmethane hydrocarbons and carbon monoxide. Observations have established that increases in the long-lived species such as carbon dioxide, methane, nitrous oxide, and the chlorofluorocarbons are taking place with important resulting impacts on stratospheric chemistry. Further, there is some indication that carbonyl sulfide (a major precursor to stratospheric aerosols) may have an important anthropogenic source. Growth of pollutants such as these are of concern because they act as greenhouse gases or aerosol precursors (CO2, CH4, O3, N2O, chlorofluorocarbons, carbonyl sufide, reactive sulfur), as agents for depletion of stratospheric ozone (N2O, chlorofluorocarbons), are harmful to vegetation (O3, acids) or act as nutrients (nitrate, sulfate, trace metals). The chemical interactions are important to understand, because the build up of pollutants depends not only on the rates of their release into the troposphere but on their rate of removal in the troposphere. Removal rates depend on processes which determine the rate of oxidation of the component (which for most species proceeds mainly by reaction with the hydroxyl radical) or through precipitation scavenging or dissolution in the ocean (which requires that the pollutant or its oxidation product(s) be soluble in water).

    2013-10-01

    Contemporary emotion regulation research emphasizes intrapersonal processes such as cognitive reappraisal and expressive suppression, but people experiencing affect commonly choose not to go it alone. Instead, individuals often turn to others for help in shaping their affective lives. How and under what circumstances does such interpersonal regulation modulate emotional experience? Although scientists have examined allied phenomena such as social sharing, empathy, social support, and prosocial behavior for decades, there have been surprisingly few attempts to integrate these data into a single conceptual framework of interpersonal regulation. Here we propose such a framework. We first map a "space" differentiating classes of interpersonal regulation according to whether an individual uses an interpersonal regulatory episode to alter their own or another person's emotion. We then identify 2 types of processes--response-dependent and response-independent--that could support interpersonal regulation. This framework classifies an array of processes through which interpersonal contact fulfills regulatory goals. More broadly, it organizes diffuse, heretofore independent data on "pieces" of interpersonal regulation, and identifies growth points for this young and exciting research domain.

    2017-10-01

    Full Text Available Aim/purpose - The aim of the article is to present the essence of ex post approach to sectoral regulation, to show the advantages and disadvantages of ex post regulation and to answer the question whether it is worth using in the electricity sector. Design/methodology/approach - For this purpose, a critical analysis of expert literature was made and an empirical analysis of countries that have applied ex post regulation in the electricity sector in the European Union. Two research methods were used: a case study and a comparison of changes in price and quality of services. The research period covered the period 2000-2016. Findings - It was found that ex post regulation reduces regulatory costs, does not adversely affect the quality of service and long-term rates, gives businesses the freedom of decision-making and the ability to react quickly to changes in the economy. The main disadvantages of ex post regulation are the tendency for companies to over-estimate bills for consumers, the difficulty of pursuing claims by consumers and the need to shift regulatory risk to consumers. Research implications/limitations - In the paper there was identified a research gap, i.e. the effects of ex post regulation in the electricity sector in European Union countries where such regulation was applied. Identifying the research gap will help us understand what are the advantages and disadvantages of ex post regulation and will create a model for when it is good moment to implement this in the economy. Besides identifying the research gap, further studies will be required over ex post regulation. Originality/value/contribution - The additional value of the paper is the study of ex post regulation, its essence and types. The article analyzed the effects of ex post regulation in the electricity sector and provided valuable insights into the potential risks associated with this approach to economic regulation.

A feature of this invention is that the semiconductor elements can be protected from thermal breakage, even at an abnormal ambient temperature rise at the voltage regulator for the battery charging generator, by controlling a maximum conduction ratio of a power transistor in the voltage regulator in accordance with the temperature at the voltage regulator. This is achieved through a switching device connected in series to the field coil of the generator and adapted to be controlled in accordance with an output voltage of the generator and the ambient temperature at the voltage regulator. 6 figs.

  2. Grandfather regulations, new source bias, and state air toxics regulations

    International Nuclear Information System (INIS)

    Levinson, Arik

    1999-01-01

    This paper uses plant-level data from the Census of Manufactures and the variation in toxic air pollution regulations across states to measure the effects of laws that are more stringent for new sources of pollution than for existing sources (so-called 'grandfather' regulations). Of particular interest is the resulting 'new source bias' and its effects on capital vintage and investment. Two industries are examined: commercial printing, which has a local product market; and paint manufacturing, which has a more national market. In general, there seem to be no statistically significant differences in capital vintage or investment between plants in states that grandfather new sources of pollution, plants in states that have no air toxics regulations, and plants in states that regulate both new and existing sources

    The UK Government has committed itself to reducing its carbon dioxide emissions. The challenge of successfully achieving a transition to a sustainable energy system, in the context of the UK's largely privately owned energy industry, rests on the ability of policy makers to encourage and enable the necessary changes or innovation at all levels of the energy system. This paper argues that the UK's current, dominant political paradigm or framework (the regulatory state paradigm (RSP)) and within it, the role of the economic regulator, Ofgem acts as a fundamental block to this challenge. The current economic regulatory system is based on trust in the market, or on predicted (albeit theoretical) known outcomes. To expand our regulatory system to one which can deliver a sustainable energy system requires innovation in a certain direction (as opposed to any innovation). That is the antithesis of the current process of regulation. Trust is required that Ofgem, the economic regulator, will develop rules and incentives which deliver an agreed sustainable energy goal, which is 'trusted' to be the 'right' goal. This requires Ofgem moving away from ex-ante regulation to a type of regulation where all costs, benefits and outcomes cannot be known beforehand and where they cannot necessarily be quantifiable. This has, very provisionally, been called Public Value Regulation (PVR). (author)

  7. NORM regulations

    Energy Technology Data Exchange (ETDEWEB)

    Gray, P. [ed.

    1997-02-01

    The author reviews the question of regulation for naturally occuring radioactive material (NORM), and the factors that have made this a more prominent concern today. Past practices have been very relaxed, and have often involved very poor records, the involvment of contractors, and the disposition of contaminated equipment back into commercial service. The rationale behind the establishment of regulations is to provide worker protection, to exempt low risk materials, to aid in scrap recycling, to provide direction for remediation and to examine disposal options. The author reviews existing regulations at federal and state levels, impending legislation, and touches on the issue of site remediation and potential liabilities affecting the release of sites contaminated by NORM.

  8. Risk-informed regulation

    International Nuclear Information System (INIS)

    Hoffman, D.R.

    2003-01-01

    In assessing safety for nuclear facilities, regulators have traditionally used a deterministic approach. New techniques for assessing nuclear or radiological risks make it possible for regulators to incorporate risk insights into their regulations. By 'risk-informing' the regulatory processes, independent bodies tasked with protecting the health and safety of the public can focus on those design and operational issues most important to safety. Such an approach is a move away from prescriptive regulations that were based on conservative engineering judgments toward regulations focused on issues that contribute significantly to safety. Despite the availability of probabilistic risk assessment (PRA) tools, organisations often struggle with how to best use this capability. Most international regulations are still based largely on deterministic analyses that were developed without the benefit of quantitative or measurable estimates of risk. PRA considers issues of risk in a more comprehensive manner by examining a wider spectrum of initiating events and their frequency, and considers the likelihood of events in a rigorous and comprehensive manner. In some countries, nuclear regulators are actively moving toward increasing the use of risk insights in a variety of strategic arenas, including risk-informed technical specifications (operating limits and conditions), in-service inspection and testing, programs, and assessment and enforcement actions. A risk-informed approach enhances the traditional deterministic approach by explicitly considering a broader range of safety challenges, focusing resources on the basis of risk significance, considering a broader range of counter measures to mitigate challenges, and explicitly identifying and quantifying uncertainties in analyses.

    While anthropological research has long emphasized cultural differences in whether emotions are viewed as beneficial versus harmful, psychological science has only recently begun to systematically examine those differences and their implications for emotion regulation and well-being. Underscoring the pervasive role of culture in people's emotions, we summarize research that has examined links between culture, emotion regulation, and well-being. Specifically, we focus on two questions. First, how does culture lead individuals to regulate their emotions? And second, how does culture modulate the link between emotion regulation and well-being? We finish by suggesting directions for future research to advance the study of culture and emotion regulation.

    This Regulation (No. 434-1993) was made in pursuance of the Radiation Control Act 1990 and replaces the Active Substances Regulations 1959 repealed by the Act. It entered into force on 1 September 1993. The Regulation specifies that the technical radiation protection definitions have the same meaning as in the 1990 recommendations. The Regulation provides for the licensing of persons to use radioactive substances and radiation apparatus. It prescribes activities which may only be carried out by an accredited radiation expert and regulates the use of radiation apparatus and radioactive substances as well as the disposal and transport of radiation apparatus and radioactive substances.

  12. Is self-regulation possible

    International Nuclear Information System (INIS)

    Barkenbus, J.N.

    1983-01-01

    The Nuclear Regulatory Commission's increasingly prescriptive regulation of the nuclear industry can have deleterious effects, perhaps the most serious being the shift in responsibility for safety from the utility to the NRC. Several factors account for this type of regulation including the nature and structure of the nuclear industry, public opinion and bureaucratic incentives, and the nature of the technology itself. The opportunities to create heightened industry self-regulation (performance-based regulation) deserve further examination. The key to self-regulation is to structure incentives so that it is clearly within the nuclear utilities' interests to build and operate nuclear power facilities in the safest manner possible. 27 references

    Due to the ever-increasing amounts under management and their unregulated and opaque nature, hedge funds have emerged as a key concern for policymakers. While until now, hedge funds have been left essentially unregulated, we are seeing increasing calls for regulation for both microprudential and macroprudential reasons. In our view, most calls for the regulation of hedge funds are based on a misperception of the effectiveness of financial regulations, perhaps coupled with a lack of understand...

  15. TOWARD MORE EFFECTIVE REGULATION

    J. GRAF

    2000-06-01

    This paper proposes a model relationship between the operator engaged in a hazardous activity, the regulator of that activity, and the general public. The roles and responsibilities of each entity are described in a way that allows effective communication flow. The role of the regulator is developed using the steam boiler as an example of a hazard subject to regulation; however, the model applies to any regulated activity. In this model the safety analyst has the extremely important role of communicating sometimes difficult technical information to the regulator in a way that the regulator can provide credible assurance to the general public as to the adequacy of the control of the hazardous activity. The conclusion asserts that acceptance of the model, understanding of the roles and responsibilities and definition of who communicates what information to whom will mitigate frustration on the part of each of the three entities.

    The challenges of regulating industrial chemicals remain unresolved in the United States. The Toxic Substances Control Act (TSCA) of 1976 was the first legislation to extend coverage to the regulation of industrial chemicals, both existing and newly registered. However, decisions related to both law and science that were made in passing this law inevitably rendered it ineffectual. Attempts to fix these shortcomings have not been successful. In light of the European Union's passage of innovative principles and requirements for chemical regulation, it is no longer possible to deny the opportunity and need for reform in US law and practice.

  18. Panel presentation: Should some type of incentive regulation replace traditional methods for regulating LDCs?

    International Nuclear Information System (INIS)

    Costello, K.W.

    1992-01-01

    State regulators should consider new approaches to regulating LDCs. They should seriously look at different incentive systems, even if only as an experiment, to address the major inefficiencies they see plaguing LDCs. Regulators have become more receptive in recent years to applying different incentive systems for historically heavily regulated industries such as the telecommunications and electric industries. In view of prevailing conditions in the natural gas industry, there is no good reason why regulators should not be as receptive to applying incentive systems for LDCs. For gas services offered in competitive markets, regulators should ask themselves whether regulation is necessary any longer. For services still requiring regulation, regulators should explore whether changes in traditional regulation are needed. While some PUCs have undertaken new regulatory practices, the question before them today is whether they should do more; whether, for example, states should accelerate their efforts toward adopting more flexible pricing and other incentive-based regulations or toward considering deregulating selected services. PUCs have different options. They can choose from among a large number of incentive systems. Their choices should hinge upon what they view as major sources of inefficiencies. For example, if uneconomical bypass is perceived as a problem then different price rules might constitute the cornerstone of an incentive-based policy. On the other hand, if excessive purchased-gas costs seem to be a major problem, a PUC may want to consider abolishing the PGA or modifying it in a form that would eliminate the cost-plus component

    Full Text Available The emotions has many important functions in our life such as in relation of interpersonal communication, and health. In interpersonal communicative function aimed to signal to other information about internal state. Emotions manifests in specific cognitive, behavioural, and physiological reactions, thus closely related to health. There is wide variety of ways for individuals to regulate their emotion. In this regard, there are two kinds of emotion regulation strategy; first Antecedent-focused emotion regulation consisting of situation selection, situation modification, attentional deployment, cognitive change and second, Response-focused emotion regulation consisting of suppression. The purpose of this research is to investigate personality factors relate with emotion regulation strategies. 339 students from Faculty of Psychology, Universitas Gadjah Mada were participating in this study and given The Big Five Personality Factors (Ramdhani, 2012, adaptation, and the modified version of the Emotion Regulation Scale was used, Emotion Regulation Questionnaire (John & Gross, 2004 which measure personality and emotion regulation respectively. Using multiple regression analysis, the study indicated that personality predicts emotion regulation strategies.

    Although the prolonged use of rapamycin may cause unwanted side effects such as hyperlipidemia, the underlying mechanism remains unknown. Prox1 is a transcription factor responsible for the development of several tissues including lymphatics and liver. There is growing evidences that Prox1 participates in metabolism in addition to embryogenesis. However, whether Prox1 is directly related to lipid metabolism is currently unknown. HepG2 human hepatoma cells were treated with rapamycin and total lipids were analyzed by thin layer chromatography. The effect of rapamycin on the expression of Prox1 was determined by western blotting. To investigate the role of Prox1 in triglycerides regulation, siRNA and overexpression system were employed. Rapamycin was injected into mice for 2 weeks and total lipids and proteins in liver were measured by thin layer chromatography and western blot analysis, respectively. Rapamycin up-regulated the amount of triglyceride and down-regulated the expression of Prox1 in HepG2 cells by reducing protein half-life but did not affect its transcript. The loss-of-function of Prox1 was coincident with the increase of triglycerides in HepG2 cells treated with rapamycin. The up-regulation of triglycerides by rapamycin in HepG2 cells reverted to normal levels by the compensation of Prox1 using the overexpression system. Rapamycin also down-regulated Prox1 expression but increased triglycerides in mouse liver. This study suggests that rapamycin can increase the amount of triglycerides by down-regulating Prox1 expression in hepatocytes, which means that the mammalian target of rapamycin (mTOR) signaling is important for the regulation of triglycerides by maintaining Prox1 expression.

    Methane (CH{sub 4}), nitrous oxide (N{sub 2}O) and chlorofluorocarbon (CFC) emissions contribute considerably to the anthropogenic enhancement of Earth`s greenhouse effect. The limitation of atmospheric concentrations of CH{sub 4} and N{sub 2}O is considered important also in the Climate Convention. Chlorine released from the CFCs in the stratosphere destroys ozone (O{sub 3}) and the emissions are therefore regulated with the Montreal Protocol. The greenhouse impact of CFCs might be, at least to some extent, compensated by the depletion of O{sub 3} which is also a greenhouse gas. The objective of the presentation is to assess the role of anthropogenic CH{sub 4}, N{sub 2}O, and CFC emissions in the total direct greenhouse impact due to human activities in Finland. The emission estimates for the gases are presented, as well as scenarios for emission history, future development and control potential. The greenhouse impact of the gases is compared with that of carbon dioxide (CO{sub 2}) emissions in Finland. (author)

    This paper discusses the initiative to transfer the regulation of Department of Energy (DOE) nuclear facilities to the US Nuclear Regulatory Commission (NRC). The paper gives an overview of some of the major technical, policy and legal issues that accompany this initiative. The paper focuses on specific issues and how they may be affected by external regulation of occupational radiation protection at DOE facilities. Differences between the NRC and the DOE approach to regulating nuclear safety are compared and contrasted. Some projected impacts from this transition are examined. Finally, recommendations are provided that may enhance the transition, increasing the likelihood of successful external NRC regulation

  10. Status of mixed-waste regulation

    International Nuclear Information System (INIS)

    Bahadur, S.

    1988-01-01

    Mixed waste is waste containing radionuclides regulated by the US Nuclear Regulatory Commission (NRC) under the Atomic Energy Act, as well as hazardous waste materials regulated by the Environmental Protection Agency (EPA) under the Resource Conservation and Recovery Act (RCRA). This has led to a situation of dual regulation in which both NRC and EPA regulate the same waste under requirements that at times appear conflicting. The NRC has been working with the EPA to resolve the issues associated with the dual regulation of mixed waste. Discussions between the two agencies indicate that dual regulation of mixed wastes appears technically achievable, although the procedures may be complex and burdensome to the regulated community. The staffs of both agencies have been coordinating their efforts to minimize the burden of dual regulation on state agencies and the industry. Three major issues were identified as sources of potential regulatory conflict: (a) definition and identification of mixed waste, (b) siting guidelines for disposal facilities, and (c) design concepts for disposal units

    International Nuclear Information System (INIS)

    Anderson, B.L.; Banaghan, E.

    1993-01-01

    The operating uranium enrichment gaseous diffusion plants (GDPs) in Portsmouth, Ohio and Paducah, Kentucky, which are operated for the United States Department for Energy by Martin Marietta Energy Systems (MMES), currently use a chlorofluorocarbon (CFC-114) as the primary process stream coolant. Due to recent legislation embodied in the Clean Air Act, the production of this and other related chlorofluorocarbons (CFCS) are to be phased out with no production occurring after 1995. Since the plants lose approximately 500,000 pounds per year of this process stream coolant through various leaks, the GDPs are faced with the challenge of identifying a replacement coolant that will allow continued operation of the plants. MMES formed the CFC Task Team to identify and solve the various problems associated with identifying and implementing a replacement coolant. This report includes a review of the work performed by the CFC Task Team, and recommendations that were formulated based on this review and upon original work. The topics covered include; identifying a replacement coolant, coolant leak detection and repair efforts, coolant safety concerns, coolant level sensors, regulatory issues, and an analytical decision analysis

  13. Comparison of series regulated neutral beam accel supplies with shunt regulated accel supplies

    International Nuclear Information System (INIS)

    Baker, W.; Smith, B.H.

    1976-01-01

    This study was undertaken to get a direct comparison between comparable series and shunt regulated power supplies. It is intended that the two supplies will be strictly equivalent with the same safety factors in the design of each type and the cost estimates made on the same basis. The series regulated power supply is simply a scaled up version of the 2XIIB Accel Supplies. Each supply provides 150 kV, 65 ampere, 500 ms pulse output such as will be used on the TFTR sources. The shunt regulated power supply uses high reactance transformers to provide the series impedance for the shunt regulator. The most significant difference in the performance of the two types of power supplies is that the shunt regulated supply has a minimum interrupt period of 16 ms, whereas the series regulated supply can have about 0.5 ms. Even this difference can be eliminated with a commutator circuit such as is being developed in Berkeley for the 150 kV, 20 ampere system. The 16 ms period is probably not a very serious limitation because it still permits up to 31 interrupts per 500 ms pulse. The shunt regulated system appears to be about 37 percent less expensive than the series system

  14. Effect Mechanism of Penstock on Stability and Regulation Quality of Turbine Regulating System

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available This paper studies the effect mechanism of water inertia and head loss of penstock on stability and regulation quality of turbine regulating system with surge tank or not and proposes the construction method of equivalent model of regulating system. Firstly, the complete linear mathematical model of regulating system is established. Then, the free oscillation equation and time response of the frequency that describe stability and regulation quality, respectively, are obtained. Finally, the effects of penstock are analysed by using stability region and response curves. The results indicate that the stability and regulation quality of system without surge tank are determined by time response of frequency which only depends on water hammer wave in penstock, while, for system with surge tank, the time response of frequency depending on water hammer wave in penstock and water-level fluctuation in surge tank jointly determines the stability and regulation quality. Water inertia of penstock mainly affects the stability and time response of frequency of system without surge tank as well as the stability and head wave of time response of frequency with surge tank. Head loss of penstock mainly affects the stability and tail wave of time response of frequency with surge tank.

    The two forms of natural monopoly regulation that are typically discussed in intermediate microeconomics textbooks are marginal cost pricing and average cost pricing (rate-of-return regulation). However, within the last 20 years, price-cap regulation has largely replaced rate-of-return regulation because of the former's potential to generate more…

  17. Panel presentation: Should some type of incentive regulation replace traditional methods for regulating LDCs?

    International Nuclear Information System (INIS)

    Turner, J.L.

    1992-01-01

    This paper reviews the advantages and disadvantages of using incentive regulation to provide the best service and rates for natural gas consumers and compares it to the traditional rate-of-return regulation. It discusses some of the allegations used to prevent incentive regulation such as the rate-of-return regulation provides an incentive to over-build and pad rate base, thus creating inefficiencies. The author also feels that strict competition is not necessarily beneficial and that some form of regulation is necessary. The paper goes on to outline the author's ideas of how a successful incentive plan should work while emphasizing his preference for a rate-of-return regulation. From the ratepayers' view, the incentives granted should be rewards for improvement in a utility's performance. In other words, there must be clear goals set for management and the fulfillment or lack of fulfillment should result in rewards or penalties. The author feels that incentive regulation could prove to be appropriate in the areas of demand side management such as energy conservation programs

    Hope, E.

    1994-06-01

    The report discusses the organization and behaviour of grid monopolies in the Norwegian power trade and relations to the socio-economic effectiveness. The main attention is laid on analyzing regulation mechanisms and measures leading to an efficient short-term operation and to the investment of optimum production capacity in a long run. Regarding the management, measures are discussed for increasing the efficiency of total power trade by evaluating the existing marketing function of Statnett. Some basic conditions are accounted concerning the regulation problem of grid monopolies with a particular attention to asymmetric information between the authority and the monopoly. In addition, forms of regulation and regulation mechanisms together with the incentive characteristics of these, are discussed. The existing profit regulation principles in relation to an alternative system design such as maximum price regulation combined with standard regulation, are evaluated. 16 refs., 7 figs.

    Within hunting, wildlife populations are estimated to be too high in many countries which is assumed to be due to the market failure, that each hunter harvests too little compared to what the regulator wants. This may be due to the existing regulation which, among other things, requires knowledge...... by an individual, variable tax rate. The variable tax rate is, among other things, based on the difference in marginal value of the population between the hunter and the regulator. The paper shows that the population tax/subsidy secures a first-best optimum. Thus, the population tax is a good alternative...... to the existing regulation....

    While some countries have unbundled distribution and retailing, skeptics argue that the physical attributes of electricity make retailers redundant. Instead, it is claimed that passive pass through of wholesale prices plus regulated charges for transmission and distribution suffice for customers to benefit from competitive generation markets. We review the Chilean experience with regulated retailing and pass through of wholesale prices. We argue that when energy wholesale prices are volatile and prices are stabilized, distortions emerge. Regulated retailers gain little by mitigating or correcting them. On the contrary, sometimes price distortions increase their profits. We estimate the cost of three distortions that neither regulated retailers nor the regulator have shown any interest in correcting. - Highlights: > We review Chile's experience with regulated electricity retailing. > Distortions emerge when energy wholesale prices are volatile and prices stabilized. > Regulated retailers gain little by mitigating or correcting distortions. > Sometimes price distortions increase retailers' profits. > We estimate the cost of three distortions, which retailers have not corrected.

  4. Wrecked regulation of intrinsically disordered proteins in diseases: Pathogenicity of deregulated regulators

    Directory of Open Access Journals (Sweden)

    Vladimir N. Uversky

    2014-07-01

    Full Text Available Biologically active proteins without stable tertiary structure are common in all known proteomes. Functions of these intrinsically disordered proteins (IDPs are typically related to regulation, signaling and control. Cellular levels of these important regulators are tightly regulated by a variety mechanisms ranging from firmly controlled expression to precisely targeted degradation. Functions of IDPs are controlled by binding to specific partners, alternative splicing, and posttranslational modifications among other means. In the norm, right amounts of precisely activated IDPs have to be present in right time at right places. Wrecked regulation brings havoc to the ordered world of disordered proteins, leading to protein misfolding, misidentification, and missignaling that give rise to numerous human diseases, such as cancer, cardiovascular disease, neurodegenerative diseases, and diabetes. Among factors inducing pathogenic transformations of IDPs are various cellular mechanisms, such as chromosomal translocations, damaged splicing, altered expression, frustrated posttranslational modifications, aberrant proteolytic degradation, and defective trafficking. This review presents some of the aspects of deregulated regulation of IDPs leading to human diseases.

  5. Why Do People Regulate Their Emotions? A Taxonomy of Motives in Emotion Regulation.

    Science.gov (United States)

    Tamir, Maya

    2016-08-01

    Emotion regulation involves the pursuit of desired emotional states (i.e., emotion goals) in the service of superordinate motives. The nature and consequences of emotion regulation, therefore, are likely to depend on the motives it is intended to serve. Nonetheless, limited attention has been devoted to studying what motivates emotion regulation. By mapping the potential benefits of emotion to key human motives, this review identifies key classes of motives in emotion regulation. The proposed taxonomy distinguishes between hedonic motives that target the immediate phenomenology of emotions, and instrumental motives that target other potential benefits of emotions. Instrumental motives include behavioral, epistemic, social, and eudaimonic motives. The proposed taxonomy offers important implications for understanding the mechanism of emotion regulation, variation across individuals and contexts, and psychological function and dysfunction, and points to novel research directions. © 2015 by the Society for Personality and Social Psychology, Inc.

  6. The Porphyromonas gingivalis ferric uptake regulator orthologue does not regulate iron homeostasis

    Directory of Open Access Journals (Sweden)

    Catherine Butler

    2015-09-01

    Full Text Available Porphyromonas gingivalis is a Gram-negative anaerobic bacterium that has an absolute requirement for iron which it transports from the host as heme and/or Fe2+. Iron transport must be regulated to prevent toxic effects from excess metal in the cell. P. gingivalis has one ferric uptake regulator (Fur orthologue encoded in its genome called Har, which would be expected to regulate the transport and usage of iron within this bacterium. As a gene regulator, inactivation of Har should result in changes in gene expression of several genes compared to the wild-type. This dataset (GEO accession number GSE37099 provides information on expression levels of genes in P. gingivalis in the absence of Har. Surprisingly, these genes do not relate to iron homeostasis.

    2002-01-01

    The North American gas and electricity markets are fast evolving, and regulators are currently faced with a host of issues such as market-based rates, unbundling, stranded costs, open access, and incentive regulation are surfacing as a result of deregulation. The regulatory environment in Ontario was reviewed by the author. Deregulated markets rule, from commodities to gas and electricity. Additionally, there is an evolution of traditional utility regulation. A look at deregulated markets revealed that there are regulations on boundary conditions on the deregulated market. Under the Ontario Energy Board (OEB), all generators, transmitters, distributors, and retailers of electricity must be licensed. The standard supply service (SSS) offered by electricity distributors and system gas which is still being sold by natural gas distributors continues to be regulated by OEB. One issue that was addressed was separation for revenues and costs of the utility's purchase and sale of gas business, at least for accounting purposes. The next issue discussed was cost of system gas and SSS, followed by timely signals and prudent incurred costs. Historical benefits were reviewed, such as historical commitments to low-cost electricity. Pooling transportation costs, transmission pricing continued, market-based rates, unbundling, stranded costs, open access, incentive regulation/ performance based regulation (PBR) were all discussed. Price cap on PBR, both partial and comprehensive were looked at. A requirement to review guidelines on cost of capital and an application to extend blanket approval provisions for gas storage were discussed, as they are amongst some of the challenges of the future. Other challenges include revised rules and practice and procedure; practice directions for cost awards, appeals, and other functions; confidentiality guidelines; and refinements to the role of and approaches to alternative dispute resolution. The future role of regulators was examined in light

  10. Expression profiling of genes regulated by TGF-beta: Differential regulation in normal and tumour cells

    Directory of Open Access Journals (Sweden)

    Takahashi Takashi

    2007-04-01

    Full Text Available Abstract Background TGF-beta is one of the key cytokines implicated in various disease processes including cancer. TGF-beta inhibits growth and promotes apoptosis in normal epithelial cells and in contrast, acts as a pro-tumour cytokine by promoting tumour angiogenesis, immune-escape and metastasis. It is not clear if various actions of TGF-beta on normal and tumour cells are due to differential gene regulations. Hence we studied the regulation of gene expression by TGF-beta in normal and cancer cells. Results Using human 19 K cDNA microarrays, we show that 1757 genes are exclusively regulated by TGF-beta in A549 cells in contrast to 733 genes exclusively regulated in HPL1D cells. In addition, 267 genes are commonly regulated in both the cell-lines. Semi-quantitative and real-time qRT-PCR analysis of some genes agrees with the microarray data. In order to identify the signalling pathways that influence TGF-beta mediated gene regulation, we used specific inhibitors of p38 MAP kinase, ERK kinase, JNK kinase and integrin signalling pathways. The data suggest that regulation of majority of the selected genes is dependent on at least one of these pathways and this dependence is cell-type specific. Interestingly, an integrin pathway inhibitor, RGD peptide, significantly affected TGF-beta regulation of Thrombospondin 1 in A549 cells. Conclusion These data suggest major differences with respect to TGF-beta mediated gene regulation in normal and transformed cells and significant role of non-canonical TGF-beta pathways in the regulation of many genes by TGF-beta.

    Pancreatic lipase (triacylglycerol lipase EC 3.1.1.3) is an essential enzyme in hydrolysis of dietary fat. Dietary fat, especially polyunsaturated fatty acids (PUFA), regulate pancreatic lipase (PNLIP); however, the molecular mechanism underlying this regulation is mostly unknown. As PUFA are known to regulate expression of proliferator-activated receptor gamma (PPARγ), and as we identified in-silico putative PPARγ binding sites within the putative PNLIP promoter sequence, we hypothesized that PUFA regulation of PNLIP might be mediated by PPARγ. We used in silico bioinformatics tools, reporter luciferase assay, PPARγ agonists and antagonists, PPARγ overexpression in exocrine pancreas AR42J and primary cells to study PPARγ regulation of PNLIP. Using in silico bioinformatics tools we mapped PPARγ binding sites (PPRE) to the putative promoter region of PNLIP. Reporter luciferase assay in AR42J rat exocrine pancreas acinar cells transfected with various constructs of the putative PNLIP promoter showed that PNLIP transcription is significantly enhanced by PPARγ dose-dependently, reaching maximal levels with multi PPRE sites. This effect was significantly augmented in the presence of PPARγ agonists and reduced by PPARγ antagonists or mutagenesis abrogating PPRE sites. Over-expression of PPARγ significantly elevated PNLIP transcript and protein levels in AR42J cells and in primary pancreas cells. Moreover, PNLIP expression was up-regulated by PPARγ agonists (pioglitazone and 15dPGJ2) and significantly down-regulated by PPARγ antagonists in non-transfected rat exocrine pancreas AR42J cell line cells. PPARγ transcriptionally regulates PNLIP gene expression. This transcript regulation resolves part of the missing link between dietary PUFA direct regulation of PNLIP. Copyright © 2016 Elsevier B.V.

  12. Self-regulation: the need to succeed

    The nuclear industry has long complained that it is over-regulated. Others - including the regulator - are now beginning to accept this complaint and acknowledge that perhaps the industry is over regulated and something should be done to provide relief. It is clear that regulation will not simply go away. The industry is perceived by some as one that cannot be trusted and must be closely regulated or serious health and safety consequences will result. Headlines claiming coverup of design deficiencies, allegations concerning construction problems, cheating on exams, mismanagement, intimidation of QA/QC personnel, etc., do little to dispel these concerns for the layman. This paper looks at two areas that must be considered in attempting to decrease the amount of regulator-imposed activities and increase self-regulation: 1) establish greater trust and confidence in the industry's ability to do a good job and be responsible for self-regulation; and 2) establish industry initiatives to regulate itself

  13. Nuclear regulation in transition

    Tomain, J.P.

    1986-01-01

    The current state of nuclear regulations in the USA is examined. Since Three Mile Island the regulation of the nuclear power industry has been undergoing a noticeable transition. It will be argued here that the transition is characterized by two indicia. First, the primary focus of state and federal regulators has been on the financial aspects of the industry: this is best seen in the context of decisions allocating the costs of nuclear plant cancellations. Second, decisionmaking power has been decentralized: although the regulatory history of nuclear power demonstrates the tradition of centralized decisionmaking power (i.e., formerly the primary decisionmaking body was the Atomic Energy Commission), now States share decisionmaking power with the Nuclear Regulatory Commission. In Section 1 a brief legislative history of nuclear regulation is presented to establish the assertion that nuclear regulation, both de jure and de facto, was centralized. Next, Section 2 canvasses recent United States Supreme Court opinions regarding nuclear regulation. The Court frequently acts as policymaker through the consequences of its opinions, if not by its intent. In the area of nuclear policymaking, the Court has paid allegiance recently both to the tradition of centralization and to the movement toward decentralization. This dualism is reflected in other federal court decisions as well which will be briefly mentioned. Continuing the analysis of Federal regulation, Section 3 examines the current reform efforts of the NRC. Section 4 presents an examination of State responses to nuclear plant cancellations. In this section, State administrative agency and court decisions will be examined and recent State legislation will be discussed. (author)

    Objectives Classify and describe the policy approaches used by countries to regulate e-cigarettes. Methods National policies regulating e-cigarettes were identified by (1) conducting web searches on Ministry of Health websites, and (2) broad web searches. The mechanisms used to regulate e-cigarettes were classified as new/amended laws, or existing laws. The policy domains identified include restrictions or prohibitions on product: sale, manufacturing, importation, distribution, use, product design including e-liquid ingredients, advertising/promotion/sponsorship, trademarks, and regulation requiring: taxation, health warning labels and child-safety standards. The classification of the policy was reviewed by a country expert. Results The search identified 68 countries that regulate e-cigarettes: 22 countries regulate e-cigarettes using existing regulations; 25 countries enacted new policies to regulate e-cigarettes; 7 countries made amendments to existing legislation; 14 countries use a combination of new/amended and existing regulation. Common policies include a minimum-age-of-purchase, indoor-use (vape-free public places) bans and marketing restrictions. Few countries are applying a tax to e-cigarettes. Conclusions A range of regulatory approaches are being applied to e-cigarettes globally; many countries regulate e-cigarettes using legislation not written for e-cigarettes. PMID:27903958

  1. International Religion Indexes: Government Regulation, Government Favoritism, and Social Regulation of Religion*

    Grim, Brian J.; Finke, Roger

    2014-01-01

    The study of religion is severely handicapped by a lack of adequate cross-national data. Despite the prominence of religion in international events and recent theoretical models pointing to the consequences of regulating religion, cross-national research on religion has been lacking. We strive to fill this void by developing measurement models and indexes for government regulation, government favoritism, and social regulation of religion. The indexes rely on data from an extensive coding of the 2003 International Religious Freedom Report for 196 countries and territories. Using a series of tests to evaluate the new data and indexes, we find that the measures developed are highly reliable and valid. The three indexes will allow researchers and others to measure the government’s subsidy and regulation of religion as well as the restrictions placed on religion by social and cultural forces beyond the state.

  5. Regulation of the power sector

    CERN Document Server

    2013-01-01

    Regulation of the Power Sector is a unified, consistent and comprehensive treatment of the theories and practicalities of regulation in modern power-supply systems. The need for generation to occur at the time of use occasioned by the impracticality of large-scale electricity storage coupled with constant and often unpredictable changes in demand make electricity-supply systems large, dynamic and complex and their regulation a daunting task. Conceptually arranged in four parts, this book addresses both traditional regulatory frameworks and also liberalized and re-regulated environments. First, an introduction gives a full characterization of power supply including engineering, economic and regulatory viewpoints. The second part presents the fundamentals of regulation and the third looks at the regulation of particular components of the power sector in detail. Advanced topics and subjects still open or subject to dispute form the content of the fourth part. In a sector where regulatory design is the key driver...

  6. The Porphyromonas gingivalis ferric uptake regulator orthologue binds hemin and regulates hemin-responsive biofilm development.

    Directory of Open Access Journals (Sweden)

    Catherine A Butler

    Full Text Available Porphyromonas gingivalis is a Gram-negative pathogen associated with the biofilm-mediated disease chronic periodontitis. P. gingivalis biofilm formation is dependent on environmental heme for which P. gingivalis has an obligate requirement as it is unable to synthesize protoporphyrin IX de novo, hence P. gingivalis transports iron and heme liberated from the human host. Homeostasis of a variety of transition metal ions is often mediated in Gram-negative bacteria at the transcriptional level by members of the Ferric Uptake Regulator (Fur superfamily. P. gingivalis has a single predicted Fur superfamily orthologue which we have designated Har (heme associated regulator. Recombinant Har formed dimers in the presence of Zn2+ and bound one hemin molecule per monomer with high affinity (Kd of 0.23 µM. The binding of hemin resulted in conformational changes of Zn(IIHar and residue 97Cys was involved in hemin binding as part of a predicted -97C-98P-99L- hemin binding motif. The expression of 35 genes was down-regulated and 9 up-regulated in a Har mutant (ECR455 relative to wild-type. Twenty six of the down-regulated genes were previously found to be up-regulated in P. gingivalis grown as a biofilm and 11 were up-regulated under hemin limitation. A truncated Zn(IIHar bound the promoter region of dnaA (PGN_0001, one of the up-regulated genes in the ECR455 mutant. This binding decreased as hemin concentration increased which was consistent with gene expression being regulated by hemin availability. ECR455 formed significantly less biofilm than the wild-type and unlike wild-type biofilm formation was independent of hemin availability. P. gingivalis possesses a hemin-binding Fur orthologue that regulates hemin-dependent biofilm formation.

    Hydrochlorofluorocarbons (HCFCs) are being developed as replacements for chlorofluorocarbons (CFCs) that deplete stratospheric ozone. The depletion of stratospheric ozone may increase the intensity of ultraviolet radiation at the earth's surface, which may be associated with global, adverse human health effects. The greater tropospheric lability of HCFCs, which is due to the presence of C-H bonds, reduces HCFC migration to the stratosphere; HCFCs should, therefore, cause less depletion of str...

    Pragman, Alexa A; Schlievert, Patrick M

    2004-10-01

    Staphylococcus aureus is a pathogenic microorganism that is responsible for a wide variety of clinical infections. These infections can be relatively mild, but serious, life-threatening infections may result from the expression of staphylococcal virulence factors that are coordinated by virulence regulators. Much work has been done to characterize the actions of staphylococcal virulence regulators in broth culture. Recently, several laboratories showed that transcriptional analyses of virulence regulators in in vivo animal models or in human infection did not correlate with transcriptional analyses accomplished in vitro. In describing the differences between in vitro and in vivo transcription of staphylococcal virulence regulators, we hope to encourage investigators to study virulence regulators using infection models whenever possible.

    2015-01-01

    Protein kinase A (PKA) controls diverse cellular processes and homeostasis in eukaryotic cells. Many processes and substrates of PKA have been described and among them are direct regulators of autophagy. The mechanisms of PKA regulation and how they relate to autophagy remain to be fully understood. We constructed a reporter of PKA activity in yeast to identify genes affecting PKA regulation. The assay systematically measures relative protein-protein interactions between the regulatory and catalytic subunits of the PKA complex in a systematic set of genetic backgrounds. The candidate PKA regulators we identified span multiple processes and molecular functions (autophagy, methionine biosynthesis, TORC signaling, protein acetylation, and DNA repair), which themselves include processes regulated by PKA. These observations suggest the presence of many feedback loops acting through this key regulator. Many of the candidate regulators include genes involved in autophagy, suggesting that not only does PKA regulate autophagy but that autophagy also sends signals back to PKA.

    After Fukushima accident, NRA (Nuclear Regulation Authority) was established in Japan as an independent organization from promotion. In order to perform effective and reliable nuclear regulation, it was important management organization such as nuclear regulation commission worked efficiently, and also requirements for nuclear regulation staffs engaged in actual regulatory works were of importance so as for appropriate decision making or judgments of management organization. Since regulation staffs needed professional expertise and technical judgment capabilities in wide areas including other than nuclear energy, various efforts had been done to get able regulation staffs in US, France and UK nuclear regulation organizations concerned, which became clarified after overseas investigation for this article. Since knowledge in nuclear industry could be used for effective regulation, mid-career recruitment had been employed in regulation organization of each country so as to take such knowledge and so it was important how to utilize industrial knowledge under appropriate conditions compatible with independence of regulation organization.

    There are a number of situations where mixed wastes are regulated by dual regulations and regulators. This presentation attempts to show where such duplication exists and how it evolved historically through legislative actions. The presentation includes a discussion of strategies that have been used to deal with the problems that result from duplicate regulations and jurisdictional conflicts. The RCRA and AEA regulations are really more similar than dissimilar. There are significant issues that must be worked through with the regulators. It is most important to work with your regulators early in process. The following are suggestions for dealing with the regulators. (1) Know the regulations in advance of discussions. (2) Begin dialogue with the regulator(s) as early as possible and get to know the people you will be dealing with -- and let them know you. (3) Explain the technical/regulatory issues/problems that you face at your facility in sufficient detail that they are clearly understood, and work with the regulator(s) to reasonably address them in the language/requirements of the permit. (4) Always attempt to comply with the regulations first before going in with a variance request -- document your efforts, and be honest with your assessment of issues. (5) Don't be adversarial -- remember that the regulator has the same objectives as you do. 1 tab

    Using a proven reliable method of CFD to study the regulating performance of a sliding regulation valve with a conical spool and rugby body. The numerical simulation results indicate that no matter where the spool is located, the flow field always has a vortex at the center of the valve body; When the spool is at the origin, the vortex and resistance coefficient of the valve are the minimum; When the spool moves from the origin to the right (the opening of the valve becomes smaller) to reach a certain position later, vortex currents also begin to appear around the tube wall behind the orifice. In addition, the vortex increases as the throttling port decreases whereas the resistance coefficient of the valve ascends slowly with the increase of the deviation of the spool and the rise in series; This type of regulating valve has S type (slow at both ends, sensitive at the center) flow characteristics at the stroke, and is not affected by the size of Re.

    1991-02-01

    The Nuclear Regulatory Commission (NRC) monitors incentive programs established by state regulators in order to obtain current information and to consider the potential safety effects of the incentive programs as applied to nuclear units. The current report is an update of NUREG/CR-5509, Incentive Regulation of Nuclear Power Plants by State Public Utility Commissions, published in December 1989. The information in this report was obtained from interviews conducted with each state regulator and each utility with a minimum entitlement of 10%. The agreements, orders, and settlements from which each incentive program was implemented were reviewed as required. The interviews and supporting documentation form the basis for the individual state reports describing the structure and financial impact of each incentive program. The programs currently in effect represent the adoption of an existing nuclear performance incentive program proposal and one new program. In addition, since 1989 a number of nuclear units have been included in one existing program; while one program was discontinued and another one concluded. 6 refs., 27 tabs

    Energy Technology Data Exchange (ETDEWEB)

    Homburger, F [ed.

    1985-01-01

    This volume assesses the impact of new scientific knowledge on the testing and regulation of chemicals, including food additives, drugs, cosmetics, pesticides, and other commercial substances. Apart from describing the newest tests, regulations, and risk assessment strategies, chapters reflect changes forced by both the growing need for cost containment and the mounting pressure to find alternatives to animal testing. Based on an international congress, the book also brings the advantage of diversity in the background and nationality of the authors, thus allowing a view of central problems according to the different interests of academics, industry scientists, government scientists, and regulators. The book opens with coverage of national and international regulations designed to prevent and control damage to human health and the environment. Topics range from basic problems of policy design and enforcement to the specific requirements for chemical regulation in developing countries. The next chapters cover new tests, systems, and assays used in in vivo safety testing. Readers will find a critical assessment of tests used to determine teratogenicity, mutagenicity, carcinogenicity, neurotoxicity and chemical lethality. Other topics include factors operating in the public perception of chemical hazards, guidelines for decision making in the management and regulation of risks, and future trends in the methodology of safety evaluation. The volume concludes with an overview of in vitro methods for testing hepatotoxicity. Several short-term in vitro test models and limited in vivo bioassays are presented and evaluated in terms of their capacity to substitute for long-term animal studies. Expert and thorough in its coverage, the book offers a wealth of technical and practical information for toxicologists, pharmacologists, industrial policy makers, and government regulators. (orig.).

    2008-12-01

    Full Text Available Although self-regulation research is fragmented over several interdisciplinary areas and theories, the concept of self-regulation could represent a cohesive force for integrating different areas of psychology, such as clinical, educational, or organisational psychology. This paper focuses on self-regulation within the educational framework and elaborates the concept of self-regulated learning. Current advances in self-regulated learning research indicated that concepts, such as cognition and motivation, need to be integrated into a coherent self-regulation model. Two models that integrate cognitive and motivational constructs are described in this paper, namely the motivational and cognitive self-regulation components described by Pintrich and colleagues (e.g., Garcia & Pintrich 1994, and a six component model of self-regulated learning provided by Boekaerts (1997. These models were used to formulate new and parsimonious organisational constructs that classify self-regulation components into proactive and defensive self-regulation patterns. At the end, the applicative value of the models and the need for further research, regarding the question of specific self-regulation failures (the depressive self-regulation pattern, are being discussed.

  8. Targeted genome regulation via synthetic programmable transcriptional regulators

    KAUST Repository

    Piatek, Agnieszka Anna

    2016-04-19

    Regulation of gene transcription controls cellular functions and coordinates responses to developmental, physiological and environmental cues. Precise and efficient molecular tools are needed to characterize the functions of single and multiple genes in linear and interacting pathways in a native context. Modular DNA-binding domains from zinc fingers (ZFs) and transcriptional activator-like proteins (TALE) are amenable to bioengineering to bind DNA target sequences of interest. As a result, ZF and TALE proteins were used to develop synthetic programmable transcription factors. However, these systems are limited by the requirement to re-engineer proteins for each new target sequence. The clustered regularly interspaced palindromic repeats (CRISPR)/CRISPR associated 9 (Cas9) genome editing tool was recently repurposed for targeted transcriptional regulation by inactivation of the nuclease activity of Cas9. Due to the facile engineering, simplicity, precision and amenability to library construction, the CRISPR/Cas9 system is poised to revolutionize the functional genomics field across diverse eukaryotic species. In this review, we discuss the development of synthetic customizable transcriptional regulators and provide insights into their current and potential applications, with special emphasis on plant systems, in characterization of gene functions, elucidation of molecular mechanisms and their biotechnological applications. © 2016 Informa UK Limited, trading as Taylor & Francis Group

  9. Re-Framing Biotechnology Regulation.

    Science.gov (United States)

    Peck, Alison

    Biotechnology is about to spill the banks of federal regulation. New genetic engineering techniques like CRISPR-Cas9 promise revolutionary breakthroughs in medicine, agriculture, and public health—but those techniques would not be regulated under the terms of the Coordinated Framework for Regulation of Biotechnology. This revolutionary moment in biotechnology offers an opportunity to correct the flaws in the framework, which was hastily patched together at the advent of the technology. The framework has never captured all relevant technologies, has never satisfied the public that risk is being effectively managed, and has never been accessible to small companies and publicly-funded labs that increasingly are positioned to make radical, life-saving innovations. This Article offers a proposal for new legislation that would reshape biotechnology regulation to better meet these goals. Key reforms include tying regulation to risk rather than technology category; consolidating agency review; capturing distinct regulatory expertise through inter-agency consultations; creating a clearinghouse to help guide applicants and disseminate information; setting up more comprehensive monitoring of environmental effects; and providing federal leadership to fill key data gaps and address socio-economic impacts.

    The regulation of Natural Gas. Natural gas Regulation clarifies and consolidates the legal and institutional framework for development of the industry through six principal elements: 1) Establishment of a vision of the industry. 2) Development of regulatory objectives. 3) Determination of relationships among industry participants. 4) Clear specification of the role of PEMEX in the industry. 5) Definition of the functions of the Regulatory authority. 6) Creation of a transition regime. In parallel with the development of the substantive legal framework, the law of the Comision Reguladora de Energia (CRE) was also enacted by Congress in October 1995 to strength the institutional framework and implement the legal changes. This law defines the CRE as an agency of the Energy Ministry with technical, operational, and budgetary autonomy, and responsibility for implementing natural gas industry regulation. (Author)

    Genetically modified organisms (GMOs) are created by biotechnology to serve people with much benefit while may impose risks to ecological environment and human health and therefore need careful regulation. During the past two decades, GMOs have been well developed in China and so has their corresponding regulation. This paper reviews and comments the multiple aspects of mainly the agricultural GMOs, including their safety assessment, control measures, trade activities, import, labels, and GM food, which have been prescribed by the corresponding laws, regulations and administrative measures. It is held that till present a framework for regulation of agricultural GMOs and GM food has been established basically in China, while a more comprehensive system for regulation of all kinds of GMOs and all kinds of related activities is still needed at present and in the future.

    Motor-vehicle crashes were the second leading cause of injury death for adults aged 65-84years in 2014. Some older drivers choose to self-regulate their driving to maintain mobility while reducing driving risk, yet the process remains poorly understood. Data from 729 older adults (aged ≥60years) who joined an older adult ride service program between April 1, 2010 and November 8, 2013 were analyzed to define and describe classes of driving self-regulation. Latent class analysis was employed to characterize older adult driving self-regulation classes using driving frequency and avoidance of seven driving situations. Logistic regression was used to explore associations between characteristics affecting mobility and self-regulation class. Three classes were identified (low, medium, and high self-regulation). High self-regulating participants reported the highest proportion of always avoiding seven risky driving situations and the lowest driving frequency followed by medium and low self-regulators. Those who were female, aged 80years or older, visually impaired, assistive device users, and those with special health needs were more likely to be high self-regulating compared with low self-regulating. Avoidance of certain driving situations and weekly driving frequency are valid indicators for describing driving self-regulation classes in older adults. Understanding the unique characteristics and mobility limitations of each class can guide optimal transportation strategies for older adults. Published by Elsevier Ltd.

    A radiation-tolerant, ultra-low-dropout linear regulator can operate between -150 and 150 C. Prototype components were demonstrated to be performing well after a total ionizing dose of 1 Mrad (Si). Unlike existing components, the linear regulator developed during this activity is unconditionally stable over all operating regimes without the need for an external compensation capacitor. The absence of an external capacitor reduces overall system mass/volume, increases reliability, and lowers cost. Linear regulators generate a precisely controlled voltage for electronic circuits regardless of fluctuations in the load current that the circuit draws from the regulator.

    Full Text Available The following article examines the role of parents in the development of children's self-regulation of energy intake. Various paths of parental influence are offered based on the literature on parental influences on children's emotion self-regulation. The parental paths include modeling, responses to children's behavior, assistance in helping children self-regulate, and motivating children through rewards and punishments. Additionally, sources of variation in parental influences on regulation are examined, including parenting style, child temperament, and child-parent attachment security. Parallels in the nature of parents' role in socializing children's regulation of emotions and energy intake are examined. Implications for future research are discussed.

    Young, middle-aged, and older adults' emotion regulation strategies in interpersonal problems were examined. Participants imagined themselves in anger- or sadness-eliciting situations with a close friend. Factor analyses of a new questionnaire supported a 4-factor model of emotion regulation strategies, including passivity, expressing emotions, seeking emotional information or support, and solving the problem. Results suggest that age differences in emotion regulation (such as older adults' increased endorsement of passive emotion regulation relative to young adults) are partially due to older adults' decreased ability to integrate emotion and cognition, increased prioritization of emotion regulation goals, and decreased tendency to express anger.

    Full Text Available The paper looks into the diverse aspects of qualifications system regulation, designed for balancing the supply and demand in the labor and educational service markets. Both the objects and mechanisms of such regulation are described. Special attention is given to institutions, involved in regulation of qualifications, and their jurisdiction. Another emphasis is on the industry-related regulation of qualifications which proved to be effective both on the national and European level. Such structures were first established on the national levels to regulate the qualifications and ensure their comparability and compatibility, given the economic globalization and growing labor and academic mobility. The author points out the role of the ministries of education and labor in maintaining a steady qualifications system, and outlines the positive experience of Great Britain using the industry councils for continuing development of qualifications system.

    The purpose of the present study was to examine relationships between child eating self-regulation, child non-eating self-regulation, and child BMIz in a low-income sample of Hispanic families with preschoolers. The eating in the absence of hunger task as well as parent-report of child satiety responsiveness and food responsiveness were used to assess child eating self-regulation. Two laboratory tasks assessing executive functioning, a parent questionnaire assessing child effortful control (a temperament dimension related to executive functioning), and the delay of gratification and gift delay tasks assessing child emotion regulation were used to assess child non-eating self-regulation. Bivariate correlations were run among all variables in the study. Hierarchical linear regression analyses assessed: (1) child eating self-regulation associations with the demographic, executive functioning, effortful control, and emotion regulation measures; and (2) child BMI z-score associations with executive functioning, effortful control, emotion regulation measures, and eating self-regulation measures. Within child eating self-regulation, only the two parent-report measures were related. Low to moderate positive correlations were found between measures of executive functioning, effortful control, and emotion regulation. Only three relationships were found between child eating self-regulation and other forms of child self-regulation: eating in the absence of hunger was positively associated with delay of gratification, and poor regulation on the gift delay task was associated positively with maternal reports of food responsiveness and negatively with parent-reports of satiety responsiveness. Regression analyses showed that child eating self-regulation was associated with child BMIz but other forms of child self-regulation were not. Implications for understanding the role of self-regulation in the development of child obesity are discussed. Copyright © 2015 Elsevier Ltd. All

    Agricultural pesticide use in Viet Nam has more than tripled since 1990. However, pesticide legislation and regulations have not been developed in response to this large increase in usage, as a result of which pesticides pose a serious threat to human health and the environment. This paper identifies the need to improve pesticide regulations in Viet Nam through a comparative analysis of pesticide regulations in Viet Nam and the United States of America, where the rate of acute poisoning among agricultural workers is much lower than in Viet Nam and where information pertaining to pesticide regulations is made accessible to the public. The analysis identified several measures that would help to improve Viet Nam's pesticide regulations. These include enhancing pesticide legislation, clarifying the specific roles and active involvement of both the environmental and health sectors; performing a comprehensive risk-benefit evaluation of pesticide registration and management practices; improving regulations on pesticide suspension and cancellation, transport, storage and disposal; developing import and export policies and enhancing pesticide-related occupational safety programmes.

    Full Text Available MicroRNAs play a crucial role in the progression of spinal cord ischemia/reperfusion injury (SCII. The role of miR-448 and SIRT1 in SCII was investigated in this study, to provide further insights into prevention and improvement of this disorder. In this study, expressions of miR-448 and SIRT1 protein were determined by qRT-PCR and western blot, respectively. Flow cytometry was used to analyze cell apoptosis. The endogenous expression of genes was modulated by recombinant plasmids and cell transfection. Dual-luciferase reporter assay was performed to determine the interaction between miR-448 and SIRT1. The Basso, Beattie, and Bresnahan score was used to measure the hind-limb function of rat. The spinal cord ischemia reperfusion injury model of adult rats was developed by abdominal aorta clamping, and the nerve function evaluation was completed by motor deficit index score. In SCII tissues and cells treated with hypoxia, miR-448 was up-regulated while SIRT1 was down-regulated. Hypoxia treatment reduced the expression of SIRT1 through up-regulating miR-448 in nerve cells. Up-regulation of miR-448 induced by hypoxia promoted apoptosis of nerve cells through down-regulating SIRT1. Down-regulated miR-448 improved neurological function and hind-limb motor function of rats with SCII by up-regulating SIRT1. Down-regulated miR-448 inhibited apoptosis of nerve cells and improved neurological function by up-regulating SIRT1, which contributes to relieving SCII.

  11. Regulation of gas infrastructure expansion

    De Joode, J.

    2012-01-01

    The topic of this dissertation is the regulation of gas infrastructure expansion in the European Union (EU). While the gas market has been liberalised, the gas infrastructure has largely remained in the regulated domain. However, not necessarily all gas infrastructure facilities - such as gas storage facilities, LNG import terminals and certain gas transmission pipelines - need to be regulated, as there may be scope for competition. In practice, the choice of regulation of gas infrastructure expansion varies among different types of gas infrastructure facilities and across EU Member States. Based on a review of economic literature and on a series of in-depth case studies, this study explains these differences in choices of regulation from differences in policy objectives, differences in local circumstances and differences in the intrinsic characteristics of the infrastructure projects. An important conclusion is that there is potential for a larger role for competition in gas infrastructure expansion.

  12. Measuring Individual Differences in Emotion Regulation: The Emotion Regulation Profile-Revised (ERP-R

    Directory of Open Access Journals (Sweden)

    Delphine Nelis

    2011-02-01

    Full Text Available The main purpose of this study was to validate a new instrument aimed to assess emotion regulation: the Emotion Regulation Profile-Revised (ERP-R. Exploratory factor analyses yielded two theoretically meaningful factors: down-regulation of negative emotions and up-regulation of positive emotions. Internal reliability scores of the two factors were good. Findings showed evidence of convergent/discriminant validity, with ERP-R scores being independent of non verbal reasoning and verbal skills while positively related to emotional intelligence and to relevant personality dimensions. There was also preliminary evidence of criterion validity. ERP-R scores also demonstrated incremental validity to predict a number of criteria over and above emotional intelligence and emotional stability. Overall, the results show a clear 2 factors solution for the ERP-R and high correlations with convergent and divergent scales as well as good criterion and incremental validities.

  14. Successful emotion regulation requires both conviction and skill: beliefs about the controllability of emotions, reappraisal, and regulation success.

    2017-09-01

    To succeed in self-regulation, people need to believe that it is possible to change behaviour and they also need to use effective means to enable such a change. We propose that this also applies to emotion regulation. In two studies, we found that people were most successful in emotion regulation, the more they believed emotions can be controlled and the more they used an effective emotion regulation strategy - namely, cognitive reappraisal. Cognitive reappraisal moderated the link between beliefs about the controllability of emotion and success in emotion regulation, when reappraisal was measured as a trait (Study 1) or manipulated (Study 2). Such moderation was found when examining the regulation of disgust elicited by emotion-inducing films (Study 1), and the regulation of anger elicited by real political events (Study 2). We discuss the implications of our findings for research and practice in emotion regulation.

    2001-07-01

    After much debate and controversy, the Bush administration announced on April 12, 2001, that it would implement the Health Insurance Portability and Accountability Act (HIPAA) privacy regulations issued by the Clinton administration in December of 2000. The privacy regulations became effective on April 14, 2001. Although the regulations are considered final, the Secretary of the Department of Health and Human Services has the power to modify the regulations at any time during the first year of implementation. These regulations affect how a patient's health information is used and disclosed, as well as how patients are informed of their privacy rights. As "covered entities," physicians have until April 14, 2003, to comply fully with the HIPAA privacy regulations, which are more than 1,500 pages in length. This article presents a basic overview of the new and complex regulations and highlights practical information about physicians' compliance with the regulations. However, this summary of the HIPAA privacy regulations should not be construed as legal advice or an opinion on specific situations. Please consult an attorney concerning your compliance with HIPAA and the regulations promulgated thereunder.

  18. Evolving Role of the Power Sector Regulator: A Clean Energy Regulators Initiative Report

    Energy Technology Data Exchange (ETDEWEB)

    Zinaman, O.; Miller, M.; Bazilian, M.

    2014-04-01

    This paper seeks to briefly characterize the evolving role of power sector regulation. Given current global dynamics, regulation of the power sector is undergoing dramatic changes. This transformation is being driven by various factors including technological advances and cost reductions in renewable energy, energy efficiency, and demand management; increasing air pollution and climate change concerns; and persistent pressure for ensuring sustainable economic development and increased access to energy services by the poor. These issues add to the already complex task of power sector regulation, of which the fundamental remit remains to objectively and transparently ensure least-cost service delivery at high quality. While no single regulatory task is trivial to undertake, it is the prioritization and harmonization of a multitude of objectives that exemplifies the essential challenge of power sector regulation. Evolving regulatory roles can be understood through the concept of existing objectives and an additional layer of emerging objectives. Following this categorization, we describe seven existing objectives of power sector regulators and nine emerging objectives, highlighting key challenges and outlining interdependencies. This essay serves as a preliminary installment in the Clean Energy Regulatory Initiative (CERI) series, and aims to lay the groundwork for subsequent reports and case studies that will explore these topics in more depth.

  19. Helping Others Regulate Emotion Predicts Increased Regulation of One's Own Emotions and Decreased Symptoms of Depression.

    Although much research considers how individuals manage their own emotions, less is known about the emotional benefits of regulating the emotions of others. We examined this topic in a 3-week study of an online platform providing training and practice in the social regulation of emotion. We found that participants who engaged more by helping others (vs. sharing and receiving support for their own problems) showed greater decreases in depression, mediated by increased use of reappraisal in daily life. Moreover, social regulation messages with more other-focused language (i.e., second-person pronouns) were (a) more likely to elicit expressions of gratitude from recipients and (b) predictive of increased use of reappraisal over time for message composers, suggesting perspective-taking enhances the benefits of practicing social regulation. These findings unpack potential mechanisms of socially oriented training in emotion regulation and suggest that by helping others regulate, we may enhance our own regulatory skills and emotional well-being.

  5. Epigenetic Regulation of Adipokines

    Directory of Open Access Journals (Sweden)

    Tho X. Pham

    2017-08-01

    Full Text Available Adipose tissue expansion in obesity leads to changes in the expression of adipokines, adipocyte-specific hormones that can regulate whole body energy metabolism. Epigenetic regulation of gene expression is a mechanism by which cells can alter gene expression through the modifications of DNA and histones. Epigenetic mechanisms, such as DNA methylation and histone modifications, are intimately tied to energy metabolism due to their dependence on metabolic intermediates such as S-adenosylmethionine and acetyl-CoA. Altered expression of adipokines in obesity may be due to epigenetic changes. The goal of this review is to highlight current knowledge of epigenetic regulation of adipokines.

    Pashkov, Vitalii; Harkusha, Andrii

    Achieved level of technical progress moves us closer and closer to practical use of 3-d bioprinting technologies in real life. Such perspective raise a wide variety of crucial legal issues from the acceptable model of regulation of the science and its' societal effects to problems of the commercialization of the technology and potential restrictions of its use. Some key points on concept of legal regulation of abovementioned sphere is a base of this study. Scientific discussion on 3-D bioprinting, European Union`s and US experience in patenting of 3-D bioprinting technologies, European Medicine Agency (EMA) or the US Food and Drug Administration (FDA) regulations, European Medical Technology Industry Association (EUCOMED) Acts. Article is based on dialectical, comparative, analytic, synthetic and comprehensive research methods. General debate of last few years comes down to an attempt to resolve hesitation between legal attempts for regulation of 3-D biobrinting and concept of complete prohibition of such activities. An adequate response to the mentioned challenge is a reasonable position between some aspects of prohibition and self-regulation, resulting in a moderate number of regulations and standards for developing and marketing. Such regulations may concern an intellectual property (IP) rights, regulation of distribution, premarket restrictions, control mechanism etc. Scientific approach and regulatory settlement of 3-D bioprinting sphere must unite to achieve a fair balance between the interests of humanity and of individuals - on the one hand, and development of science and business benefits for stakeholders - on the other. The main instruments for this must be balanced regulation of intellectual property (IP) rights, regulation of access and distribution, premarket restrictions, control mechanism etc.

    2006-01-01

    Tetraspanin CD9 has been shown to regulate cell-cell fusion in sperm-egg fusion and myotube formation. However, the role of CD9 in osteoclast, another multinucleated cell type, is not still clear. Therefore, we investigated the role of CD9 in osteoclast differentiation. CD9 was expressed in osteoclast lineage cells and its expression level increased during the progression of RANKL-induced osteoclastogenesis. KMC8, a neutralizing antibody specific to CD9, significantly suppressed RANKL-induced multinucleated osteoclast formation and the mRNA expression of osteoclast differentiation marker genes. To define CD9-regulated osteoclastogenic signaling pathway, MAPK pathways were examined. KMC8 induced long-term phosphorylation of p44/42 MAPK, but not of p38 MAPK. Constitutive activation of p44/42 MAPK by overexpressing constitutive-active mutant of MEK1 almost completely blocked osteoclast differentiation. Taken together, these results suggest that CD9 expressed on osteoclast lineage cells might positively regulate osteoclastogenesis via the regulation of p44/42 MAPK activity

    Full Text Available Excess energy intake, without a compensatory increase of energy expenditure, leads to obesity. Several molecules are involved in energy homeostasis regulation and new ones are being discovered constantly. Appetite regulating hormones such as ghrelin, peptide tyrosine-tyrosine and amylin or incretins such as the gastric inhibitory polypeptide have been studied extensively while other molecules such as fibroblast growth factor 21, chemerin, irisin, secreted frizzle-related protein-4, total bile acids, and heme oxygenase-1 have been linked to energy homeostasis regulation more recently and the specific role of each one of them has not been fully elucidated. This mini review focuses on the above mentioned molecules and discusses them in relation to their regulation by the macronutrient composition of the diet as well as diet-induced weight loss.

    Methyl chloroform and CFC-113 ascended in the cleaning hierarchy as versatile, aggressive, yet safe parts cleaners. Now the U.S. Environmental Protection Agency and its global equivalents want these choice solvents to step down. Saddled with an ozone depletion potential higher than anybody cares to talk about, regulators put methyl chloroform (MCF or 1,1,1-trichloroethane) and CFC-113 (trichlorotrifluoroethane) on a list of chlorofluorocarbons (CFCs) slated for phase-out by Jan. 1, 1996. The phase-out bans production and imports of the blacklisted parts cleaners. But as production declines, the cost of cleaning components with an ozone-depleter gets prohibitive. The steep federal excise tax, shorten shelf-life of CFCs and new labeling rule are reason enough to stop using MCF and CFC-113 and start looking at alternative cleaning processes. The labeling rule mandates warning labels on any component ''manufactured with or containing'' an ozone-depleter as of May 15, 1993. There are no acceptable ''drop-in'' alternatives. Even trichloroethylene (TCE), perchloroethylene (PERC) and methylene chloride (MC) require some equipment modifications. There are plenty of other cleaning alternatives vying for the parts-cleaning throne

    The R-22 refrigerant has been used as a substitute of chlorofluorocarbons in refrigerating machineries but its use will become prohibited very soon. This paper raises the problem of its replacement by other HFC or natural fluids. The problem of natural fluids like ammonia or propane concerns their toxicity, flammability and explosion risk. If a regulation about the greenhouse effect is defined, the performance of the installation will be the decisive parameter for the choice of a refrigerant. R-22 fluid has multiple applications from air-conditioning systems to freezing tunnels and the most suitable substitutes will be different from one application to the other. The different criteria that influence the choice of a refrigerating fluid are: the condensation pressure, the delivery temperature, the compressor volume efficiency, the volume refrigerating power, the coefficient of performance, the variation of vaporization temperature, the global greenhouse effect, the toxicity, flammability and explosive character. A comparison between several fluids has been performed with a single-stage airtight compressor of 10 m{sup 3}/h, at a 40 deg. C constant condensation temperature, a 5 deg. C overheating and a 3 deg. C under-cooling. (J.S.) 6 refs.

    This paper explores quantification of regulator's preference factor (RPF) in electricity-environment coordinated regulation system. Based on social welfare economics, we articulately depict RPF's qualitative concept and its economic meaning. Then, applying abstract functions (i.e., abstract social welfare function, abstract utility function, and abstract production function), we deduce the partial-social-welfare elasticity, and build the mathematics model of maximizing social welfare. We nest this elasticity into the model's Kuhn-Tucker conditions, and obtain RPF's definition formula. By solving the Kuhn-Tucker conditions, we get RPF's quantitative formula, which solves the problem of hard to quantify regulator's preference in electricity-environment coordinated regulation system. The result shows that RPF only has relationship to subsystems' production function, and is independent of social welfare function and subsystems' utility function. Finally, we provide an empirical research based on the western region of China from year 1995 to 2004. It reveals that regulator has relative stability preference to mitigating pollutants. And validity test confirms that the empirical result is fit well to the practice. The RPF is truly a more general and valid instrument to measure regulator's preference in its regulated field.

    Emotion regulation predicts positive academic outcomes like learning, but little is known about "why". Effective emotion regulation likely promotes learning by broadening the scope of what may be attended to after an emotional event. One hundred twenty-six 6- to 13-year-olds' (54% boys) regulation of sadness was examined for changes in…

  3. Deciphering Transcriptional Regulation

    DEFF Research Database (Denmark)

    Valen, Eivind

    The myriad of cells in the human body are all made from the same blueprint: the human genome. At the heart of this diversity lies the concept of gene regulation, the process in which it is decided which genes are used where and when. Genes do not function as on/off buttons, but more like a volume...... mostly near the start of the gene known as the promoter. This region contains patterns scattered in the DNA that the TFs can recognize and bind to. Such binding can prompt the assembly of the pre-initiation complex which ultimately leads to transcription of the gene. In order to achieve the regulation...... on what characterizes a hippocampus promoter. Pairing CAGE with TF binding site prediction we identi¿ed a likely key regulator of hippocampus. Finally, we developed a method for CAGE exploration. While the DeepCAGE library characterized a full 1.4 million transcription initiation events it did not capture...

    The main objective of this paper is to analyse the effect of electricity regulation on economic growth. Although the relationship between electricity consumption and economic growth has been extensively analysed in the empirical literature, this framework has not been used to estimate the effect of electricity regulation on economic growth. Understanding this effect is essential for the assessment of regulatory policy. Specifically, we assess the effects of two major areas of regulation, rene...

  6. Analysis of combinatorial regulation: scaling of partnerships between regulators with the number of governed targets.

    2010-05-01

    Full Text Available Through combinatorial regulation, regulators partner with each other to control common targets and this allows a small number of regulators to govern many targets. One interesting question is that given this combinatorial regulation, how does the number of regulators scale with the number of targets? Here, we address this question by building and analyzing co-regulation (co-transcription and co-phosphorylation networks that describe partnerships between regulators controlling common genes. We carry out analyses across five diverse species: Escherichia coli to human. These reveal many properties of partnership networks, such as the absence of a classical power-law degree distribution despite the existence of nodes with many partners. We also find that the number of co-regulatory partnerships follows an exponential saturation curve in relation to the number of targets. (For E. coli and Bacillus subtilis, only the beginning linear part of this curve is evident due to arrangement of genes into operons. To gain intuition into the saturation process, we relate the biological regulation to more commonplace social contexts where a small number of individuals can form an intricate web of connections on the internet. Indeed, we find that the size of partnership networks saturates even as the complexity of their output increases. We also present a variety of models to account for the saturation phenomenon. In particular, we develop a simple analytical model to show how new partnerships are acquired with an increasing number of target genes; with certain assumptions, it reproduces the observed saturation. Then, we build a more general simulation of network growth and find agreement with a wide range of real networks. Finally, we perform various down-sampling calculations on the observed data to illustrate the robustness of our conclusions.

  7. Believing Is Doing: Emotion Regulation Beliefs Are Associated With Emotion Regulation Behavioral Choices and Subjective Well-Being

    2017-03-01

    Full Text Available Research in emotion regulation has begun to examine various predictors of emotion regulation choices, including individual differences and contextual variables. However, scant attention has been paid to the extent to which people’s beliefs about the specific consequences of emotion regulation strategies for the components of an emotional response and long-term well-being predict their behavioral regulatory choices and, in turn, their subjective well-being. Participants completed measures to assess their beliefs about the consequences of functional and dysfunctional strategies, behavioral choices of emotion regulation strategies in negative scenarios, and subjective well-being. The model that fit the data indicated partial mediation whereby beliefs were associated with approximately 9% of the variance in choices. Emotion regulation choices were related to subjective well-being, with an additional direct effect between beliefs and well-being. This suggests beliefs play a role in people’s regulatory choices. Future research should explore how beliefs interact with individual differences and contextual variables to better understand why people regulate their emotions in different ways and, ultimately, to help individuals make healthy emotion regulation choices.

    Mansfield, Daniel; Kryger, Meir

    2015-12-01

    Current hours of service regulations governing commercial truck drivers in place in the United States, Canada, Australia, and the European Union are summarized and compared to facilitate the assessment of the effectiveness of such provisions in preventing fatigue and drowsiness among truck drivers. Current hours of service provisions governing commercial truck drivers were derived from governmental sources. The commercial truck driver hours of service provisions in the United States, Canada, and the European Union permit drivers to work 14 hours and those of Australia permit drivers to work 12 hours a day on a regular basis. The regulations do not state what a driver may do with time off. They are consistent with a driver being able to drive after 24 hours without sleep. They do not take into account circadian rhythm by linking driving or rest to time of day. Current hours of service regulations governing commercial truck drivers leave gaps--permitting drivers to work long hours on a regular basis, permitting driving after no sleep for 24 hours, and failing to take into account the importance of circadian rhythm, endangering the public safety and the truck drivers themselves.

  11. Panel presentation: Should some type of incentive regulation replace traditional methods for regulating LDC's?

    International Nuclear Information System (INIS)

    Farman, R.D.

    1992-01-01

    This paper discusses the wants and fears of gas utility companies with regards to incentive regulation. The idea of replacing the traditional rate-of-return regulation with incentive regulation sound very desirous in that it should provide greater management flexibility, quicker and more streamlined regulatory processes, and utility financial rewards based on how well customer needs are met. However, the main fear is that this could result in arbitrary, inappropriate productivity or efficiency targets, or would embody a risk/reward ratio skewed more heavily toward financial penalties than opportunities to increase earnings. The paper presents some of the obstacles of traditional regulation which include a lack of incentive to minimize operational costs; a lack of incentive to introduce new technology, products, or services; prevent the need for flexibility to compete in contestable markets; and the diversion caused by utility managers having to manage the regulatory process rather than delivering value to customers. The paper concludes by comparing the incentive regulation program used in the telecommunications industry to the natural gas industry to demonstrate why the success of the telecommunications model doesn't apply to the gas utilities incentive model

    2017-09-01

    Ketamine is an anesthetic commonly used in low-income countries and has recently been shown to be effective for treatment-resistant depression. However, the illicit manufacturing, trafficking, and nonmedical use of ketamine are increasing globally, and its illicit use poses major public health challenges in many countries. To review the nonmedical use of ketamine in selected countries and its regulatory control. We conducted a review of literature identified from searches of the China National Knowledge Infrastructure (CNKI) (1979-2016) and PubMed databases, supplemented by additional references identified by the authors. Special attention was given to the regulation of ketamine. Illicit manufacturing, trafficking, and use of ketamine appear to have begun on a large scale in several Asian nations, and it has subsequently spread to other regions. Regulations governing availability of ketamine vary across countries, but there is a clear trend toward tighter regulations. As nonmedical use of ketamine and its harmful consequences have worsened globally, stricter controls are necessary. Appropriate regulation of ketamine is important for international efforts to control ketamine's cross-border trafficking and its nonmedical use.

  13. Regulating nuclear fuel waste

    International Nuclear Information System (INIS)

    1995-01-01

    When Parliament passed the Atomic Energy Control Act in 1946, it erected the framework for nuclear safety in Canada. Under the Act, the government created the Atomic Energy Control Board and gave it the authority to make and enforce regulations governing every aspect of nuclear power production and use in this country. The Act gives the Control Board the flexibility to amend its regulations to adapt to changes in technology, health and safety standards, co-operative agreements with provincial agencies and policy regarding trade in nuclear materials. This flexibility has allowed the Control Board to successfully regulate the nuclear industry for more than 40 years. Its mission statement 'to ensure that the use of nuclear energy in Canada does not pose undue risk to health, safety, security and the environment' concisely states the Control Board's primary objective. The Atomic Energy Control Board regulates all aspects of nuclear energy in Canada to ensure there is no undue risk to health, safety, security or the environment. It does this through a multi-stage licensing process

    Overall, Nickola C; Simpson, Jeffry A

    2015-02-01

    Insecurely attached people have relatively unhappy and unstable romantic relationships, but the quality of their relationships depends on how their partners regulate them. Some partners find ways to regulate the emotional and behavioral reactions of insecurely attached individuals, which promotes greater relationship satisfaction and security. We discuss attachment theory and interdependence dilemmas, and then explain how and why certain responses by partners assuage the cardinal concerns of insecure individuals in key interdependent situations. We then review recent studies illustrating how partners can successfully regulate the reactions of anxiously and avoidantly attached individuals, yielding more constructive interactions. We finish by considering how these regulation processes can create a more secure dyadic environment, which helps to improve relationships and attachment security across time.

    2012-03-01

    Self-regulation is a core aspect of adaptive human behavior that has been studied, largely in parallel, through the lenses of social and personality psychology as well as cognitive psychology. Here, we argue for more communication between these disciplines and highlight recent research that speaks to their connection. We outline how basic facets of executive functioning (working memory operations, behavioral inhibition, and task-switching) may subserve successful self-regulation. We also argue that temporary reductions in executive functions underlie many of the situational risk factors identified in the social psychological research on self-regulation and review recent evidence that the training of executive functions holds significant potential for improving poor self-regulation in problem populations.

  4. Initial state regulation of investor-owned utilities

    International Nuclear Information System (INIS)

    Savitski, D.W.

    2001-01-01

    This paper examines state initiation of public service (or utility) commission regulation of investor-owned utilities (IOUs) using an economic theory of regulation. The decision to regulate IOUs is assumed to have depended on the strength of competing interest groups, e.g. consumers and producers, and on institutional factors, e.g. whether commissioners were appointed or elected. Regulators, which then had jurisdiction over IOU rates, are assumed to have been optimizing agents. The potential benefits of regulation, in turn, translated into pressure to initiate regulation. To test this, a hazard model is applied to state-level data. On the demand side of the regulation market, the distribution of federal power and population density were unrelated, while a set of time dummies was positively related to the probability that a state initiated regulation. On the supply side, the fraction of the population that was urban and whether the governor was Republican or not were positively and negatively related to this probability

    2000-01-01

    A newly proposed regulation in Ontario will require the mandatory tracking of 358 airborne pollutants by the electricity sector as well as by other large industrial facilities such as iron and steel manufacturers and petroleum refiners. If passed, the regulation would make Ontario the first jurisdiction in the world to require monitoring and reporting of a full suite of major greenhouse gases, including smog and acid-rain causing emissions. The proposed regulation also provides for immediate public access to any reported information. Ontario residents can comment on the proposed regulation through the Environmental Bill of Rights registry. A new, more severe hazardous waste regulation will also take effect on March 31, 2001, whereby testing for 88 contaminants will be done according to a new standard called the Toxicity Characteristic Leaching Procedure (TCLP). This new regulation also introduces a new 'derived from' rule which requires that a listed hazardous waste keep its classification until it can be demonstrated otherwise. Ontario's list of hazardous wastes has been updated to include 129 new chemicals and industrial processes. The Ontario Ministry has also adopted the Canada-wide Standards for Particulate Matter and Ozone, as well as the Canada-wide Standards for mercury emissions from base metal smelters as well as from incineration of sewage sludge and municipal, medical, hazardous waste

    2017-01-01

    Differentiating regulation is a promising approach to agri-environmental regulation that may potentially reduce the environmental impact of agriculture at the lowest possible costs for the farmers and society, but also possesses a number of challenges. In this article, we explore the challenges...... to the legitimacy of agri-environmental regulation that occurs when the regulatory regime changes from general regulation to differentiated regulation. The analysis is based on a case study of the implementation of the Buffer zone act in Denmark – a regulation that prevents agricultural production in a 10 (later 9......) meter fringe around selected waterbodies. We distinguish between two different ways of legitimizing: Producing knowledge and participation. We conclude that to harvest some of the obvious benefits of differentiated regulation a number of challenges must be resolved, 1) ensuring legitimacy...

  7. Redox regulation of cell proliferation: Bioinformatics and redox proteomics approaches to identify redox-sensitive cell cycle regulators.

    Science.gov (United States)

    Foyer, Christine H; Wilson, Michael H; Wright, Megan H

    2018-03-29

    Plant stem cells are the foundation of plant growth and development. The balance of quiescence and division is highly regulated, while ensuring that proliferating cells are protected from the adverse effects of environment fluctuations that may damage the genome. Redox regulation is important in both the activation of proliferation and arrest of the cell cycle upon perception of environmental stress. Within this context, reactive oxygen species serve as 'pro-life' signals with positive roles in the regulation of the cell cycle and survival. However, very little is known about the metabolic mechanisms and redox-sensitive proteins that influence cell cycle progression. We have identified cysteine residues on known cell cycle regulators in Arabidopsis that are potentially accessible, and could play a role in redox regulation, based on secondary structure and solvent accessibility likelihoods for each protein. We propose that redox regulation may function alongside other known posttranslational modifications to control the functions of core cell cycle regulators such as the retinoblastoma protein. Since our current understanding of how redox regulation is involved in cell cycle control is hindered by a lack of knowledge regarding both which residues are important and how modification of those residues alters protein function, we discuss how critical redox modifications can be mapped at the molecular level.

    Infection with pathogens activates the endothelial cell and its sustained activation may result in impaired endothelial function. Endothelial dysfunction contributes to the pathologic angiogenesis that is characteristic of infection-induced inflammatory pathway activation. Nucleotide-binding oligomerization domain-containing protein 1 (NOD1) is a protein receptor which recognizes bacterial molecules and stimulates an immune reaction in various cells; however, the underlying molecular mechanisms in the regulation of inflammation-triggered angiogenesis are not fully understood. Here we report that peroxisome proliferator-activated receptor gamma (PPARγ)-mediated miR-125a serves as an important regulator of NOD1 agonist-mediated angiogenesis in endothelial cells by directly targeting NOD1. Treatment of human umbilical vein endothelial cells with natural PPARγ ligand, 15-Deoxy-Delta12,14-prostaglandin J2, led to inhibition of NOD1 expression; contrarily, protein levels of NOD1 were significantly increased by PPARγ knockdown. We report that PPARγ regulation of NOD1 expression is a novel microRNA-mediated regulation in endothelial cells. MiR-125a expression was markedly decreased in human umbilical vein endothelial cells subjected to PPARγ knockdown while 15-Deoxy-Delta12,14-prostaglandin J2 treatment increased the level of miR-125a. In addition, NOD1 is closely regulated by miR-125a, which directly targets the 3′ untranslated region of NOD1. Moreover, both overexpression of miR-125a and PPARγ activation led to inhibition of NOD1 agonist-induced tube formation in endothelial cells. Finally, NOD1 agonist increased the formation of cranial and subintestinal vessel plexus in zebrafish, and this effect was abrogated by concurrent PPARγ activation. Overall, these findings identify a PPARγ-miR-125a-NOD1 signaling axis in endothelial cells that is critical in the regulation of inflammation-mediated angiogenesis. - Highlights: • Expression of NOD1 is regulated by

  16. A preliminary assessment of sources of nitrate in springwaters, Suwannee River basin, Florida

    Science.gov (United States)

    Katz, B.G.; Hornsby, H.D.

    1998-01-01

    A cooperative study between the Suwannee River Water Management District (SRWMD) and the U.S. Geological Survey (USGS) is evaluating sources of nitrate in water from selected springs and zones in the Upper Floridan aquifer in the Suwannee River Basin. A multi-tracer approach, which consists of the analysis of water samples for naturally occurring chemical and isotopic indicators, is being used to better understand sources and chronology of nitrate contamination in the middle Suwannee River region. In July and August 1997, water samples were collected and analyzed from six springs and two wells for major ions, nutrients, and dissolved organic carbon. These water samples also were analyzed for environmental isotopes [18O/16O, D/H, 13C/12C, 15N/14N] to determine sources of water and nitrate. Chlorofluorocarbons (CCl3F, CCl2F2, and C2Cl3F3) and tritium (3H) were analyzed to assess the apparent ages (residence time) of springwaters and water from the Upper Floridan aquifer. Delta 15N-NO3 values in water from the six springs range from 3.94 per mil (Little River Springs) to 8.39 per mil (Lafayette Blue Spring). The range of values indicates that nitrate in the sampled springwaters most likely originates from a mixture of inorganic (fertilizers) and organic (animal wastes) sources, although the higher delta 15N-NO3 value for Lafayette Blue Spring indicates that an organic source of nitrogen is likely at this site. Water samples from the two wells sampled in Lafayette County have high delta 15N-NO3 values of 10.98 and 12.1 per mil, indicating the likelihood of an organic source of nitrate. These two wells are located near dairy and poultry farms, where leachate from animal wastes may contribute nitrate to ground water. Based on analysis of chlorofluorocarbons in ground water, the mean residence time of water in springs ranges from about 12 to 25 years.

    Background Freon includes a number of gaseous, colorless chlorofluorocarbons. Although freon is generally considered to be a fluorocarbon of relatively low toxicity; significantly detrimental effects may occur upon over exposure. The purpose of the present study is to investigate whether occupational exposure to fluorocarbons can induce arterial hypertension, myocardial ischemia, cardiac arrhythmias, elevated levels of plasma lipids and renal dysfunction. Methods This comparative cross-sectional study was conducted at the cardiology clinic of the Suez Canal Authority Hospital (Egypt). The study included 23 apparently healthy male workers at the refrigeration services workshop who were exposed to fluorocarbons (FC 12 and FC 22) and 23 likewise apparently healthy male workers (unexposed), the control group. All the participants were interviewed using a pre-composed questionnaire and were subjected to a clinical examination and relevant laboratory investigations. Results There were no significant statistical differences between the groups studied regarding symptoms suggesting arterial hypertension and renal affection, although a significantly higher percentage of the studied refrigeration services workers had symptoms of arrhythmias. None of the workers had symptoms suggesting coronary artery disease. Clinical examination revealed that the refrigeration services workers had a significantly higher mean pulse rate compared to the controls, though no significant statistical differences were found in arterial blood pressure measurements between the two study groups. Exercise stress testing of the workers studied revealed normal heart reaction to the increased need for oxygen, while sinus tachycardia was detected in all the participants. The results of Holter monitoring revealed significant differences within subject and group regarding the number of abnormal beats detected throughout the day of monitoring (p < 0.001). There were no significant differences detected in the

    Despite growing research on emotion regulation (ER) strategies and psychopathology, research has primarily focused on identifying one-to-one associations between ER strategies and symptoms. Thus, little is known about how patterns in the repertoires of ER strategies are associated with different mental disorders. We utilised latent class analysis to identify distinct repertoires of ER strategies, and their links with various psychopathology domains (i.e., anxiety, depression, disordered eating, borderline personality). Participants (N = 531) reported on their use of seven ER strategies in six recalled stressful contexts, as well as on their symptoms of psychopathology. We identified five classes of ER strategies: Low Regulators (n = 168), High Regulators (n = 140), Adaptive Regulators (n = 99), Worriers/Ruminators (n = 96) and Avoiders (n = 28). Generally, High Regulators and Worriers/Ruminators endorsed greater levels of psychopathology, relative to Low and Adaptive Regulators. Our findings underscore the importance of characterising the dynamics of ER repertoires when seeking to understand links between ER strategies and psychopathology.

    Full Text Available Histamine is a critical mediator of IgE/mast cell-mediated anaphylaxis, a neurotransmitter and a regulator of gastric acid secretion. Histamine is a monoamine synthesized from the amino acid histidine through a reaction catalyzed by the enzyme histidine decarboxylase (HDC, which removes carboxyl group from histidine. Despite the importance of histamine, transcriptional regulation of HDC gene expression in mammals is still poorly understood. In this review, we focus on discussing advances in the understanding of molecular regulation of mammalian histamine synthesis.

    Fiechter, A.

    1982-12-01

    Metabolic regulation which is based on endogeneous and exogeneous process variables which may act constantly or time dependently on the living cell is discussed. The observed phenomena of the regulation are the result of physical, chemical, and biological parameters. These parameters are identified. Ethanol is accumulated as an intermediate product and the synthesis of biomass is reduced. This regulatory effect of glucose is used for the aerobic production of ethanol. Very high production rates are thereby obtained. Understanding of the regulation mechanism of the glucose effect has improved. In addition to catabolite repression, several other mechanisms of enzyme regulation have been described, that are mostly governed by exogeneous factors. Glucose also affects the control of respiration in a third class of yeasts which are unable to make use of ethanol as a substrate for growth. This is due to the lack of any anaplerotic activity. As a consequence, diauxic growth behavior is reduced to a one-stage growth with a drastically reduced cell yield. The pulse chemostat technique, a systematic approach for medium design is developed and medium supplements that are essential for metabolic control are identified.

Subjects between 18-65 years of age with a body mass index recording within the last two years. serious medical illness, eating disorders or pregnant women. Behavioural variables: self-regulation of body weight (Inventory of self-control of body weight), perceived self-efficacy in weight regulation (Inventory of perceived self-efficacy in weight regulation) and locus control in weight regulation (Inventory of locus control in weight regulation). Anthropometric variables: weight (kg) and height (m), body mass index. One hundred and six participants were included: 32 were obese, 28 overweight and 46 normal weight. Significant differences were found between the 3 study groups for total scale of self-efficacy (F=61.77; pcontrol (F=13.92; p=.019), other weighty influences of locus control (F=9.21; pcontrol (F=3.50; p=.011). The relationship between body mass index and behavioural variables of self-efficacy, self-regulation and locus control, suggests the need for healthcare professionals to include psychological factors of behaviour in any preventive action and intervention directed at weight control.

    International Nuclear Information System (INIS)

    Sridharan, Savitha; Jain, Kirti; Basu, Alakananda

    2011-01-01

    Autophagy is a process of self-degradation that maintains cellular viability during periods of metabolic stress. Although autophagy is considered a survival mechanism when faced with cellular stress, extensive autophagy can also lead to cell death. Aberrations in autophagy are associated with several diseases, including cancer. Therapeutic exploitation of this process requires a clear understanding of its regulation. Although the core molecular components involved in the execution of autophagy are well studied there is limited information on how cellular signaling pathways, particularly kinases, regulate this complex process. Protein kinases are integral to the autophagy process. Atg1, the first autophagy-related protein identified, is a serine/threonine kinase and it is regulated by another serine/threonine kinase mTOR. Emerging studies suggest the participation of many different kinases in regulating various components/steps of this catabolic process. This review focuses on the regulation of autophagy by several kinases with particular emphasis on serine/threonine protein kinases such as mTOR, AMP-activated protein kinase, Akt, mitogen-activated protein kinase (ERK, p38 and JNK) and protein kinase C that are often deregulated in cancer and are important therapeutic targets

    2015-01-01

    The regulatory framework, compliance requirement, efficacy, safety, and marketing of cosmetic products are considered the most important factors for growth of the cosmetic industry. There are different regulatory bodies across the globe that have their own insights for regulation; moreover, governments such as the United States, European Union, and Japan follow a stringent regulatory framework, whereas cosmetics are not so much strictly regulated in countries such as India, Brazil, and China. The alignment of a regulatory framework will play a significant role in the removal of barriers to trade, growth of market at an international level, innovation in the development and presentation of new products, and most importantly safety and efficacy of the marketed products. The present contribution gives insight into the important cosmetic regulations in areas of premarket approval, ingredient control, and labeling and warnings, with a special focus on the cosmetic regulatory environments in the United States, European Union, Japan, and India. Most importantly, the authors highlight the dark side of cosmetics associated with allergic reactions and even skin cancer. The importance of cosmetic regulations has been highlighted by dint of which the society can be healthier, accomplished by more stringent and harmonized regulations.

    Full Text Available I show that it is optimal to separate non-benevolent regulators when regulated projects are large. Separation prevents regulators from coordinating to appropriate all of the agent's informational rent when they know the type of the latter; therefore, there is a trade-off between saving on informational rent and efficiency, since the game between the regulators induced by separation causes further distortions when compared to the allocation under one regulator. When the informational rent at stake is large due to the size of the project, separation is the optimal institutional answer.

    Human reproduction is interrelated with privacy. However, in most countries where new reproductive technologies are used public regulations have been passed to provide a legal framework for such technologies. This interference in private life can be justified by the need to control medical intervention in the human reproductive process. But in order to find a balance between public regulations and other social regulations, this article analyses the impact private regulation may have on issues raised by reproductive technologies. It also addresses the issue of the influence of private bodies on the drafting of public regulations.

    MicroRNAs (miRNAs) regulate gene expression by binding mRNA and inhibiting translation and/or inducing degradation of the associated transcripts. Expression levels of miRNAs have been shown to be altered in response to environmental toxicants, thus impacting cellular function and influencing disease risk. Transcription factors (TFs) are known to be altered in response to environmental toxicants and play a critical role in the regulation of miRNA expression. To date, environmentally-responsive TFs that are important for regulating miRNAs remain understudied. In a state-of-the-art analysis, we utilized an in silico bioinformatic approach to characterize potential transcriptional regulators of environmentally-responsive miRNAs. Using the miRStart database, genomic sequences of promoter regions for all available human miRNAs (n = 847) were identified and promoter regions were defined as − 1000/+500 base pairs from the transcription start site. Subsequently, the promoter region sequences of environmentally-responsive miRNAs (n = 128) were analyzed using enrichment analysis to determine overrepresented TF binding sites (TFBS). While most (56/73) TFs differed across environmental contaminants, a set of 17 TFs was enriched for promoter binding among miRNAs responsive to numerous environmental contaminants. Of these, one TF was common to miRNAs altered by the majority of environmental contaminants, namely SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin, subfamily A, member 3 (SMARCA3). These identified TFs represent candidate common transcriptional regulators of miRNAs perturbed by environmental toxicants. - Highlights: • Transcription factors that regulate environmentally-modulated miRNA expression are understudied • Transcription factor binding sites (TFBS) located within DNA promoter regions of miRNAs were identified. • Specific transcription factors may serve as master regulators of environmentally-mediated microRNA expression.

  9. Risk based regulation: a convenient concept for legislation and regulation in the field of technical risks?

    International Nuclear Information System (INIS)

    Seiler, J.H.

    1998-01-01

    Legislation and regulation concerning risk activities are traditionally based on deterministic safety measures. This may lead to inefficient results: sometimes the law requires safety measures which are - from an economic viewpoint - not justified because of their poor cost-effectiveness; sometimes it does not require safety measures although they would be very efficient. The risk based regulation approach wants to make the law more efficient and to get more safety at less costs. Legislation and regulation should be based on terms of risk rather than on deterministic rules. Risk should be expressed in quantitative terms and risk regulation should be based on the cost-effectiveness of safety measures. Thus a most efficient (in the sense of the economic analysis of the law) strategy for safety and environmental law could be established. The approach is economically reasonable and theoretically convincing. Its practical implementation however raises a lot of technical and legal questions. The project 'Risk Based Regulation' (1996-1999), sponsored by the Swiss National Fund for Scientific Research, intends to evaluate the practical feasibility of the approach from a technical and a legal view. It contains a general part which describes the risk based regulation approach and its legal and technical questions, case studies which try to practically implement the risk based regulation approach; the case studies are: storage and management of explosives in the army, storage and management of explosives for non-military purposes, safety at work, accident prevention in the non-professional field (mainly road accidents), fire protection, transportation of dangerous goods, waste disposal: traditional waste, waste disposal: radioactive waste, nuclear energy (reactor safety), a synthesis with recommendations for the future legislation and regulation in the field of technical risks. The paper presents the project and its preliminary results. (author)

    MicroRNAs (miRNAs) regulate gene expression by binding mRNA and inhibiting translation and/or inducing degradation of the associated transcripts. Expression levels of miRNAs have been shown to be altered in response to environmental toxicants, thus impacting cellular function and influencing disease risk. Transcription factors (TFs) are known to be altered in response to environmental toxicants and play a critical role in the regulation of miRNA expression. To date, environmentally-responsive TFs that are important for regulating miRNAs remain understudied. In a state-of-the-art analysis, we utilized an in silico bioinformatic approach to characterize potential transcriptional regulators of environmentally-responsive miRNAs. Using the miRStart database, genomic sequences of promoter regions for all available human miRNAs (n = 847) were identified and promoter regions were defined as − 1000/+500 base pairs from the transcription start site. Subsequently, the promoter region sequences of environmentally-responsive miRNAs (n = 128) were analyzed using enrichment analysis to determine overrepresented TF binding sites (TFBS). While most (56/73) TFs differed across environmental contaminants, a set of 17 TFs was enriched for promoter binding among miRNAs responsive to numerous environmental contaminants. Of these, one TF was common to miRNAs altered by the majority of environmental contaminants, namely SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin, subfamily A, member 3 (SMARCA3). These identified TFs represent candidate common transcriptional regulators of miRNAs perturbed by environmental toxicants. - Highlights: • Transcription factors that regulate environmentally-modulated miRNA expression are understudied • Transcription factor binding sites (TFBS) located within DNA promoter regions of miRNAs were identified. • Specific transcription factors may serve as master regulators of environmentally-mediated microRNA expression

    The main topic of this report is the economic regulation of the transmission system operators (To) in the Nordic countries (Denmark, Finland, Norway and Sweden). The purpose of this report is to give an overview of the design of the economic regulation and compare the main elements of the regulation between the countries. There is one To in each country. For all countries, the revenues of the Tos are regulated by yearly decisions. In Finland, Norway and Sweden the regulators set an annual revenue cap. In Denmark, the To sets the tariffs according to budget, while the regulator approves the annual report and thereby also approves the tariffs ex post. The economic regulation of TSOs includes both regulation of system operations and the regulation of network operations. Chapter 3 describes in brief the main responsibilities of the system operator in each country and how the costs related to these tasks are regulated. Norway regulates the system operation costs, where 60 percent of the costs are based on a cost-norm which is evaluated periodically. In Finland and Sweden these costs are considered as non-controllable and are passed through directly in the revenue cap. In Denmark only costs considered as necessary at efficient operation shall be included in the tariffs, and the regulators have the opportunity to exclude costs based on this. There are no benchmark or efficiency requirements in the Danish regulation. In chapter 4 the main elements of the economic regulation of network operations are described and compared in tables. All countries regulate the network operations of the TSO. In Denmark there are no explicit efficiency requirements, and the regulation is based on a non-profit principle. The TSO only gets a return based on a price adjustment on its capital base as of 2005. In Finland, Norway and Sweden the regulation include efficiency requirements or benchmarking of costs. In Norway this regards 60 percent of total costs related to the network operations

We introduce a novel experimental design that attempts to disentangle...... potential confounds in previous experiments. A key feature of our experimental design is to have the exact same regulations chosen endogenously as those that are imposed exogenously. When we compare the same regulations chosen endogenously to those externally imposed, we observe no differences in extraction...... endogenous regulations with communication and exogenous regulations without communication. Our results suggest that externally imposed regulations do not crowd out intrinsic motivations in the lab and they confirm that communication facilitates cooperation to reduce extraction....

  15. Social regulation of emotion: messy layers

    Science.gov (United States)

    Kappas, Arvid

    2013-01-01

    Emotions are evolved systems of intra- and interpersonal processes that are regulatory in nature, dealing mostly with issues of personal or social concern. They regulate social interaction and in extension, the social sphere. In turn, processes in the social sphere regulate emotions of individuals and groups. In other words, intrapersonal processes project in the interpersonal space, and inversely, interpersonal experiences deeply influence intrapersonal processes. Thus, I argue that the concepts of emotion generation and regulation should not be artificially separated. Similarly, interpersonal emotions should not be reduced to interacting systems of intraindividual processes. Instead, we can consider emotions at different social levels, ranging from dyads to large scale e-communities. The interaction between these levels is complex and does not only involve influences from one level to the next. In this sense the levels of emotion/regulation are messy and a challenge for empirical study. In this article, I discuss the concepts of emotions and regulation at different intra- and interpersonal levels. I extend the concept of auto-regulation of emotions (Kappas, 2008, 2011a,b) to social processes. Furthermore, I argue for the necessity of including mediated communication, particularly in cyberspace in contemporary models of emotion/regulation. Lastly, I suggest the use of concepts from systems dynamics and complex systems to tackle the challenge of the “messy layers.” PMID:23424049

    Nuclear fuel cycle is regulated as a whole in Japan by the law concerning regulation of nuclear raw materials, nuclear fuel materials and reactors (hereafter referred to as ''the law concerning regulation of reactors''), which was published in 1957, and has been amended 13 times. The law seeks to limit the use of atomic energy to peaceful objects, and nuclear fuel materials are controlled centering on the regulation of enterprises which employ nuclear fuel materials, namely regulating each enterprise. While the permission and report of uses are necessary for the employment of nuclear materials under Article 52 and 61 of the law concerning regulation of reactors, the permission provisions are not applied to three kinds of enterprises of refining, processing and reprocessing and the persons who install reactors as the exceptions in Article 52, when nuclear materials are used for the objects of the enterprises themselves. The enterprises of refining, processing and reprocessing and the persons who install reactors are stipulated respectively in the law. Accordingly the nuclear material regulations are applied only to the users of small quantity of such materials, namely universities, research institutes and hospitals. The nuclear fuel materials used in Japan which are imported under international contracts including the nuclear energy agreements between two countries are mostly covered by the security measures of IAEA as internationally controlled substances.

  18. Does electricity (and heat) network regulation have anything to learn from fixed line telecoms regulation?

    International Nuclear Information System (INIS)

    Pollitt, Michael

    2010-01-01

    The purpose of this paper is to examine the lessons from the recent history of telecoms deregulation for electricity (and by implication heat) network regulation. We do this in the context of Ofgem's RPI-X rate at 20 review of energy regulation in the UK, which considers whether RPI-X-based price regulation is fit for purpose after over 20 years of operation in energy networks. We examine the deregulation of fixed line telecoms in the UK and the lessons which it seems to suggest. We then apply the lessons to electricity networks in the context of a possible increase in distributed generation directly connected to local distribution networks. We conclude that there is the possibility of more parallels over time and suggest several implications of this for the regulation of electricity and heat networks. (author)

  19. Emotion regulation and psychopathology: the role of gender.

    Science.gov (United States)

    Nolen-Hoeksema, Susan

    2012-01-01

    This review addresses three questions regarding the relationships among gender, emotion regulation, and psychopathology: (a) are there gender differences in emotion regulation strategies, (b) are emotion regulation strategies similarly related to psychopathology in men and women, and (c) do gender differences in emotion regulation strategies account for gender differences in psychopathology? Women report using most emotion regulation strategies more than men do, and emotion regulation strategies are similarly related to psychopathology in women and men. More rumination in women compared to men partially accounts for greater depression and anxiety in women compared to men, while a greater tendency to use alcohol to cope partially accounts for more alcohol misuse in men compared to women. The literature on emotion regulation is likely missing vital information on how men regulate their emotions. I discuss lessons learned and questions raised about the relationships between gender differences in emotion regulation and gender differences in psychopathology.

  1. Arabidopsis SUMO protease ASP1 positively regulates flowering time partially through regulating FLC stability

    2016-01-01

    The initiation of flowering is tightly regulated by the endogenous and environment signals, which is crucial for the reproductive success of flowering plants. It is well known that autonomous and vernalization pathways repress transcription of FLOWERING LOCUS C (FLC), a focal floral repressor, but how its protein stability is regulated remains largely unknown. Here, we found that mutations in a novel Arabidopsis SUMO protease 1 (ASP1) resulted in a strong late-flowering phenotype under long-days, but to a lesser extent under short-days. ASP1 localizes in the nucleus and exhibited a SUMO protease activity in vitro and in vivo. The conserved Cys-577 in ASP1 is critical for its enzymatic activity, as well as its physiological function in the regulation of flowering time. Genetic and gene expression analyses demonstrated that ASP1 promotes transcription of positive regulators of flowering, such as FT, SOC1 and FD, and may function in both CO-dependent photoperiod pathway and FLC-dependent pathways. Although the transcription level of FLC was not affected in the loss-of-function asp1 mutant, the protein stability of FLC was increased in the asp1 mutant. Taken together, this study identified a novel bona fide SUMO protease, ASP1, which positively regulates transition to flowering at least partly by repressing FLC protein stability.

  2. Endothelin-1 Regulation of Exercise-Induced Changes in Flow: Dynamic Regulation of Vascular Tone

    2017-10-01

    Full Text Available Although endothelin (ET-1 is a highly potent vasoconstrictor with considerable efficacy in numerous vascular beds, the role of endogenous ET-1 in the regulation of vascular tone remains unclear. The perspective that ET-1 plays little role in the on-going regulation of vascular tone at least under physiologic conditions is supported by findings that potential ET-1 constriction is minimized by the release of the vasodilator and ET-1 synthesis inhibitor, nitric oxide (NO. Indeed, ET-1 release and constriction is self-limited by ET-1-induced, endothelial ETB receptor-mediated release of NO. Moreover, even if the balance between ET-1 and NO were reversed as the result of lowered NO activity, as occurs in a number of pathophysiologies associated with endothelial dysfunction, the well-known resistance of ET-1 constriction to reversal (as determined with exogenous ET-1 precludes ET-1 in the dynamic, i.e., moment-to-moment, regulation of vascular tone. On the other hand, and as presently reviewed, findings of ET-1-dependent modulation of organ blood flow with exercise under physiologic conditions demonstrate the dynamic regulation of vascular tone by ET-1. We speculate that this regulation is mediated at least in part through changes in ET-1 synthesis/release caused by pulsatile flow-induced shear stress and NO.

  7. Situation selection is a particularly effective emotion regulation strategy for people who need help regulating their emotions.

    2018-03-01

    Situation selection involves choosing situations based on their likely emotional impact and may be less cognitively taxing or challenging to implement compared to other strategies for regulating emotion, which require people to regulate their emotions "in the moment"; we thus predicted that individuals who chronically experience intense emotions or who are not particularly competent at employing other emotion regulation strategies would be especially likely to benefit from situation selection. Consistent with this idea, we found that the use of situation selection interacted with individual differences in emotional reactivity and competence at emotion regulation to predict emotional outcomes in both a correlational (Study 1; N = 301) and an experimental field study (Study 2; N = 125). Taken together, the findings suggest that situation selection is an effective strategy for regulating emotions, especially for individuals who otherwise struggle to do so.

    2013-11-01

    Full Text Available Food availability in nature is often irregular, and famine is commonplace. Increased motivation to engage in ingestive behaviors increases the chance of survival, providing additional potential opportunities for reproduction. Because of the advantages conferred by entraining ingestive behavior to environmental conditions, neuroendocrine mechanisms regulating the motivation to acquire and ingest food have evolved to be responsive to exogenous (i.e. food stored for future consumption and endogenous (i.e. body fat stores fuel availability. Motivated behaviors like eating occur in two phases. The appetitive phase brings animals into contact with food (e.g. foraging, food hoarding, and the more reflexive consummatory phase results in ingestion (e.g., chewing, swallowing. Quantifiable appetitive behaviors are part of many the natural ingestive behavioral repertoire of species such as hamsters and humans. This review summarizes current knowledge about neuroendocrine regulators of ingestive behavior, with an emphasis appetitive behavior. We will discuss hormonal regulators of appetitive ingestive behaviors, including the orexigenic hormone ghrelin, which potently stimulates foraging and food hoarding in Siberian hamsters. This section includes a discussion of the hormone leptin, its relation to endogenous fat stores, and its role in food deprivation-induced increases in appetitive ingestive behaviors. Next, we discuss how hormonal regulators interact with neurotransmitters involved in the regulation of ingestive behaviors, such as NPY, AgRP and alpha-MSH, to regulate ingestive behavior. Finally, we discuss the potential impact that perinatal nutrient availability can have on the neuroendocrine regulation of ingestive behavior. Understanding the hormonal mechanisms that connect metabolic fuel availability to central appetite regulatory circuits should provide a better understanding of the neuroendocrine regulation of the motivation to engage in ingestive

  9. Synthetic risks, risk potency, and carcinogen regulation.

    Viscusi, W K; Hakes, J K

    1998-01-01

    This article analyzes a comprehensive sample of over 350 chemicals tested for carcinogenicity to assess the determinants of the probability of regulation. Controlling for differences in the risk potency and noncancer risks, synthetic chemicals have a significantly higher probability of regulation overall: this is due to the greater likelihood of U.S. Food and Drug Administration (FDA) regulation. Measures of risk potency increase the probability of regulation by the U.S. Environmental Protection Agency (EPA), have a somewhat weaker positive effect on regulation by the U.S. Occupational Safety and Health Administration (OSHA), and decrease the likelihood of regulation by the FDA. The overall regulatory pattern is one in which the FDA targets synthetic chemicals and chemicals that pose relatively minor cancer risk. The EPA particularly performed more sensibly than many critics have suggested.

    The work of the Nuclear Technology Committee (NTC) is characterised by the key words 'safety related regulations' and 'nuclear technology'. The rationalisation effect desired from regulations and the not unlimited number of experts qualified for working out regulations, make it necessary to establish priorities. The NTC has almost exclusively worked out regulations for nuclear powerstations and mainly for light water reactors. The program defined at present seems to cover the most important areas. Future developments can be foreseen in the execution of the part of the program not yet concluded, the maintenance of the regulations and, depending on the development of nuclear technology, the greater inclusion of the HTR and possibly the expansion of the regulations to fast breeder reactors and plant of the fuel circuit.

    Efficient implicit emotion regulation processes, which run without awareness, are important for human well-being. In this study, to investigate the influence of implicit emotion regulation on psychological and electrophysiological responses to gains and losses, participants were required to select between two Chinese four-character idioms to match the meaning of the third one before they performed a monetary gambling task. According to whether their meanings were related to emotion regulation, the idioms fell into two categories. Event-related potentials and self-rating emotional experiences to outcome feedback were recorded during the task. Priming emotion regulation reduced subjective emotional experience to both gains and losses and the amplitudes of the feedback-related negativity, while the P3 component was not influenced. According to these results, we suggest that the application of implicit emotion regulation effectively modulated the subjective emotional experience and the motivational salience of current outcomes without the cost of cognitive resources. This study implicates the potential significance of implicit emotion regulation in decision-making processes. © The Author (2014). Published by Oxford University Press.

    Precise regulation is fundamental to the proper functioning of enzymes in a cell. Current opinions about this, such as allosteric regulation and dynamic contribution to enzyme regulation, are experimental models and substantially empirical. Here we proposed a theoretical and thermodynamic model of enzyme regulation. The main idea is that enzyme regulation is processed via the regulation of abundance of active conformation in the reaction buffer. The theoretical foundation, experimental evidence, and experimental criteria to test our model are discussed and reviewed. We conclude that basic principles of enzyme regulation are laws of protein thermodynamics and it can be analyzed using the concept of distribution curve of active conformations of enzymes.

    2017-09-01

    Full Text Available The aim of the article is to summarize the existing approaches regarding the optimal balance of mechanisms of economic regulation and identify factors that influence the formation of the parity of state regulation and market self-regulation of economy. The analysis of the existing studies has made it possible to establish that the mixed economy model, which is organized on the basis of the market price system but uses various forms of government intervention to correct macroeconomic instability, is the most optimal one for effective development. The smoothing, preventing of negative consequences of effects of market regulators is the goal of state regulation of economy. It is substantiated that the optimal correlation of mechanisms of state regulation and market self-regulation is not a constant value. The maximum effective ratio in application of these mechanisms will not always be achieved under condition of equal government intervention and self-regulation. It depends on the country’s potential, its involvement in the system of the world market economy, level of development of the society, as well as historical features of the country’s development and phase of the economic cycle. Prospects for further research are the substantiation of a new paradigm for the formation of the parity of state regulation and market self-regulation in the context of financial uncertainty and effect of supranational regulators, growing contradictions of globalization-regionalization based on the use of the system and synergetic approach.

    2017-03-28

    Carbon catabolite repression is a crucial regulation mechanism in microorganisms, but its characteristic in Rhizopus is still unclear. We extracted a carbon regulation gene, cre , that encoded a carbon catabolite repressor protein (CRE) from Rhizopus stolonifer TP-02, and studied the regulation of CRE by real-time qPCR. CRE responded to glucose in a certain range, where it could significantly regulate part of the cellulase genes ( eg, bg, and cbh2 ) without cbh1 . In the comparison of the response of cre and four cellulase genes to carboxymethylcellulose sodium and a simple carbon source (lactose), the effect of CRE was only related to the concentration of reducing sugars. By regulating the reducing sugars to range from 0.4% to 0.6%, a glucose-containing medium with lactose as the inducer could effectively induce cellulases without the repression of CRE. This regulation method could potentially reduce the cost of enzymes produced in industries and provide a possible solution to achieve the large-scale synthesis of cellulases.

    In 1998, the French public authorities have started an ambitious energy mastery policy under the auspices of the Agency of environment and energy mastery (Ademe). One aspect of this policy concerns the R and D, industrial development and applications of automation and computerized control to the energy systems of buildings. This RCT 2000 seminar takes stock of the recent advances in this domain 7 years after the previous RCT issue. The first day of the seminar was devoted to new developments in regulation and control (ergonomics aspects, lighting systems, air conditioning in accommodations, solar systems etc..). Stress was put on the revolution expected with the introduction of domestic computer applications and Internet. This first day ended with a precise status of the standardization and future regulatory aspects.

    Full Text Available This paper reports findings from a longitudinal project in which secondary teachers were working collaboratively to support adolescents' self-regulated learning through reading (LTR in subject-area classrooms. We build from prior research to “connect the dots” between teachers' engagement in self- and co-regulated inquiry, associated shifts in classroom practice, and student self-regulation. More specifically, we investigated whether and how teachers working within a community of inquiry were mobilizing research to shape classroom practice and advance student learning. Drawing on evidence from 18 teachers and their respective classrooms, we describe findings related to the following research questions: (1 While engaged in self- and co-regulated inquiry, what types of practices did teachers enact to support LTR in their subject-area classrooms? (2 How did teachers draw on research-based resources to inform practice development? (3 What kinds of practices could be associated with gains in students' self-regulated LTR? In our discussion, we highlight contributions to understanding how teachers can be supported to situate research in authentic classroom environments and about qualities of practices supportive of students' self-regulated LTR. We also identify limitations of this work and important future directions.

    A process of making a vegetative and tuber growth regulator. The vegetative and tuber growth regulator is made by growing potato plants in a recirculating hydroponic system for a sufficient time to produce the growth regulator. Also, the use of the vegetative and growth regulator on solanaceous plants, tuber forming plants and ornamental seedlings by contacting the roots or shoots of the plant with a sufficient amount of the growth regulator to regulate the growth of the plant and one more of canopy size, plant height, stem length, internode number and presence of tubers in fresh mass. Finally, a method for regulating the growth of potato plants using a recirculating hydroponic system is described.

    Full Text Available Voluntary Sustainability Standards (VSS might develop into a viable alternative to public regulation. However, it turns on the (regulatory circumstances whether that holds true in practice. If public regulation on CSR topics is lacking, governments are unable to agree upon certain topics on a global level or diverging public regulation exists, VSS can be helpful to set global standards. Obviously, private standards will especially be helpful if they are commensurate with local public legislation (and e.g. treaties and/or are accepted by local governments. If one neglects this, numerous domestic structures might exist that frustrate VSS. Furthermore, governments have to remain vigilant as to whether these private regimes do not result in market disruption, consumer detriment or hamper trade. VSS might also compete with public arrangements which might limit the uptake of VSS. However, if public regulation exists VSS might be a viable alternative if compliance with not too compelling public norms by market participants is rather poor and the public policymaker is aiming to incentivize the better performing part of the market to embark on higher standards and thus only desires to regulate the less performing part of the market. However, of paramount importance is the effectiveness of VSS in order to be a viable alternative to public regulation. The effectiveness of VSS should be assessed using an integrated multi-disciplinary (comparative approach entailing legal, impact-assessment, legitimacy, governance and behavioural aspects. Only effective VSS in the aforementioned sense are a true alternative to public regulation.Beyond that, the legal perspective in connection with (the effectiveness of VSS is discussed, featuring FSC and UTZ Certified as an example. It is important from this perspective that VSS have a clear and sufficiently selective objective and sufficiently specific norms, are regularly evaluated, entail ‘conflict of law rules’ and

    The proper maintenance of body weight and mood are two of the most prevalent health issues present in society today. Obese humans display higher levels of mood-related disorders and the causality of such an association is unknown. A common feature of obesity is the imbalance of regulatory hormones which normally act to maintain stable energy balance and body weight. The adiposity hormone leptin is one such signal elevated in obesity with the capacity to dampen feeding behavior through action on brain circuits which regulate appetite and metabolism. Recent evidence suggests that leptin may regulate motivation through its actions within brain reward circuitry. In addition, leptin signaling within central nervous system regions that regulate cognition and emotion elicits anti-depressant like effects. Together, these data indicate that leptin may regulate the decreased motivation and mood present in obesity and depression. This review describes the capacity of leptin to regulate motivation and depression through actions within brain circuits that modulate effort-based behavior and emotion, respectively.

  5. Regulation of Meiotic Recombination

    Energy Technology Data Exchange (ETDEWEB)

    Gregory p. Copenhaver

    2011-11-09

    Meiotic recombination results in the heritable rearrangement of DNA, primarily through reciprocal exchange between homologous chromosome or gene conversion. In plants these events are critical for ensuring proper chromosome segregation, facilitating DNA repair and providing a basis for genetic diversity. Understanding this fundamental biological mechanism will directly facilitate trait mapping, conventional plant breeding, and development of genetic engineering techniques that will help support the responsible production and conversion of renewable resources for fuels, chemicals, and the conservation of energy (1-3). Substantial progress has been made in understanding the basal recombination machinery, much of which is conserved in organisms as diverse as yeast, plants and mammals (4, 5). Significantly less is known about the factors that regulate how often and where that basal machinery acts on higher eukaryotic chromosomes. One important mechanism for regulating the frequency and distribution of meiotic recombination is crossover interference - or the ability of one recombination event to influence nearby events. The MUS81 gene is thought to play an important role in regulating the influence of interference on crossing over. The immediate goals of this project are to use reverse genetics to identify mutants in two putative MUS81 homologs in the model plant Arabidopsis thaliana, characterize those mutants and initiate a novel forward genetic screen for additional regulators of meiotic recombination. The long-term goal of the project is to understand how meiotic recombination is regulated in higher eukaryotes with an emphasis on the molecular basis of crossover interference. The ability to monitor recombination in all four meiotic products (tetrad analysis) has been a powerful tool in the arsenal of yeast geneticists. Previously, the qrt mutant of Arabidopsis, which causes the four pollen products of male meiosis to remain attached, was developed as a facile system

  7. Neuroendocrine regulation of appetitive ingestive behavior.

    2013-11-15

    Food availability in nature is often irregular, and famine is commonplace. Increased motivation to engage in ingestive behaviors increases the chance of survival, providing additional potential opportunities for reproduction. Because of the advantages conferred by entraining ingestive behavior to environmental conditions, neuroendocrine mechanisms regulating the motivation to acquire and ingest food have evolved to be responsive to exogenous (i.e., food stored for future consumption) and endogenous (i.e., body fat stores) fuel availability. Motivated behaviors like eating occur in two phases. The appetitive phase brings animals into contact with food (e.g., foraging, food hoarding), and the more reflexive consummatory phase results in ingestion (e.g., chewing, swallowing). Quantifiable appetitive behaviors are part of the natural ingestive behavioral repertoire of species such as hamsters and humans. This review summarizes current knowledge about neuroendocrine regulators of ingestive behavior, with an emphasis appetitive behavior. We will discuss hormonal regulators of appetitive ingestive behaviors, including the orexigenic hormone ghrelin, which potently stimulates foraging and food hoarding in Siberian hamsters. This section includes a discussion of the hormone leptin, its relation to endogenous fat stores, and its role in food deprivation-induced increases in appetitive ingestive behaviors. Next, we discuss how hormonal regulators interact with neurotransmitters involved in the regulation of ingestive behaviors, such as neuropeptide Y (NPY), agouti-related protein (AgRP) and α-melanocyte stimulating hormone (α-MSH), to regulate ingestive behavior. Finally, we discuss the potential impact that perinatal nutrient availability can have on the neuroendocrine regulation of ingestive behavior. Understanding the hormonal mechanisms that connect metabolic fuel availability to central appetite regulatory circuits should provide a better understanding of the

  8. Lipasin, a novel nutritionally-regulated liver-enriched factor that regulates serum triglyceride levels.

    2012-08-10

    The metabolic syndrome, a common disorder including glucose intolerance and dyslipidemia, poses a major public health issue. Patients with high blood lipids, such as triglycerides, are at high risk in developing atherosclerotic cardiovascular diseases. To identify genes involved in metabolism, we performed RNA-seq experiments on the liver and fat in mice treated with a high-fat diet or fasting, and identified Gm6484 (named Lipasin) as a novel nutritionally regulated gene. Human LIPASIN is liver specific, while the mouse one is enriched in the liver and fat, including both brown and white adipose tissues. Obesity increases liver Lipasin, whereas fasting reduces its expression in fat. ANGPTL3 (Angiopoietin-like 3) and ANGPTL4 are critical regulators of blood lipids. LIPASIN shares homology with ANGPTL3's N-terminal domain that is needed for lipid regulation, and with ANGPTL4's N-terminal segment that mediates lipoprotein lipase (LPL) binding. Lipasin overexpression by adenoviruses in mice increases serum triglyceride levels, and a recombinant Lipasin inhibits LPL activity. Therefore, a potential mechanism for Lipasin-mediated triglyceride elevation is through reduced triglyceride clearance by LPL inhibition. Lipasin is thus a novel nutritionally-regulated liver-enriched factor that plays a role in lipid metabolism. Copyright © 2012 Elsevier Inc. All rights reserved.

  15. Metabotropic Regulation of Extrasynaptic GABAA Receptors

    Directory of Open Access Journals (Sweden)

    William Martin Connelly

    2013-10-01

    Full Text Available A large body of work now shows the importance of GABAA receptor-mediated tonic inhibition in regulating CNS function. However, outside of pathological conditions, there is relatively little evidence that the magnitude of tonic inhibition is itself under regulation. Here we review the mechanisms by which tonic inhibition is known to be modulated, and outline the potential behavioural consequences of this modulation. Specifically, we address the ability of protein kinase A and C to phosphorylate the extrasynaptic receptors responsible for the tonic GABAA current, and how G-protein coupled receptors can regulate tonic inhibition through these effectors. We then speculate about the possible functional consequences of regulating the magnitude of the tonic GABAA current.

    2016-01-01

    The high circulating levels of histones found in various thrombotic diseases may compromise the anticoagulant barrier of endothelial cells. We determined how histones affect endothelial procoagulant tissue factor (TF) and anticoagulant thrombomodulin (TM). Surface antigens, soluble forms, and mRNA levels of TF and TM were measured by flow cytometry, ELISA, and real-time RT-PCR, respectively. TF and TM activity were measured using procoagulant activity, thrombin generation, or chromogenic assays. Involvement of the toll-like receptor (TLR) was assessed using the neutralizing antibodies. Histones dose-dependently induced surface antigens, activity and mRNA levels of endothelial TF. Histone-treated endothelial cells significantly shortened the lag time and enhanced the endogenous thrombin potential of normal plasma, which was normalized by a TF neutralizing antibody. Histones induced phosphatidylserine and protein-disulfide isomerase expression in endothelial cells. Histones also reduced the surface antigen, activity, and mRNA levels of endothelial TM. Polysialic acid and heparin reversed the histone-induced TF up-regulation and TM down-regulation. Activated protein C did not affect the TF up-regulation, but interrupted TM down-regulation. TLR2, and TLR4 inhibitors partially blocked the TF up-regulation. Histones induced the endothelial procoagulant phenotype through TF up-regulation and TM down-regulation. The effects of histones were partly mediated by TLR2, TLR4. Strategies to inhibit the harmful effects of histones in endothelial cells may be required in order to prevent a thrombotic environment.

  19. Complex regulation controls Neurogenin3 proteolysis

    Directory of Open Access Journals (Sweden)

    Ryan Roark

    2012-10-01

    The ubiquitin proteasome system (UPS is known to be responsible for the rapid turnover of many transcription factors, where half-life is held to be critical for regulation of transcriptional activity. However, the stability of key transcriptional regulators of development is often very poorly characterised. Neurogenin 3 (Ngn3 is a basic helix–loop–helix transcription factor that plays a central role in specification and differentiation of endocrine cells of the pancreas and gut, as well as spermatogonia and regions of the brain. Here we demonstrate that Ngn3 protein stability is regulated by the ubiquitin proteasome system and that Ngn3 can be ubiquitylated on lysines, the N-terminus and, highly unusually, on non-canonical residues including cysteines and serines/threonines. Rapid turnover of Ngn3 is regulated both by binding to its heterodimeric partner E protein and by the presence of cdk inhibitors. We show that protein half-life does appear to regulate the activity of Ngn3 in vivo, but, unlike the related transcription factor c-myc, ubiquitylation on canonical sites is not a requirement for transcriptional activity of Ngn3. Hence, we characterise an important new level of Ngn3 post-translational control, which may regulate its transcriptional activity.

  20. The four key characteristics of interpersonal emotion regulation.

    Science.gov (United States)

    Niven, Karen

    2017-10-01

    Emotion researchers are increasingly interested in processes by which people influence others' feelings. Although one such process, interpersonal emotion regulation, has received particular attention in recent years, there remains confusion about exactly how to define this process. The present article aims to distinguish interpersonal emotion regulation from other, related processes by outlining its four key characteristics. Specifically, interpersonal emotion regulation is presented as a process of (i) regulation, that (ii) has an affective target, (iii) is deliberate, and (iv) has a social target. Considering these characteristics raises questions for future research concerning factors that may influence the process of interpersonal emotion regulation, why interpersonal emotion regulation sometimes fails, and whether interventions can improve people's use of interpersonal emotion regulation.

    Modern state of the problem on hygienic regulation of ionizing radiations is considered. Concepts and principles of the regulation based on risk concept are presented according to ICRP 26 and 27. Two types of risk are designated: ''absolute'' and ''relative'' ones. The concept of acceptable risk on the basis of cost - benefit ratio is substantiated. Special attention is paid to the principle of accounting the complex of health signs, when determining radiation hazard. To determine the level of permissible risk and permissible dose to population the concept of ''inadmissibility of s-tatistically significant risk'' has been developed. Standards, regulating population doses in the USSR, which are valid nowadays, are considered

    Due to increasing concerns about the environment, British Columbia has committed to reducing its 2007 greenhouse gas emissions levels by 33% in 2020 and 80% in 2050. To reach those objectives, emissions trading and offset regulations are being developed by the Climate Action Secretariat. The aim of this document is to present a first draft of the regulations to the various stakeholders, including First Nations and the general public, together with the proposed offset eligibility criteria and related process, and to get their feedback. This document is itself part of the 5-phase process of developing the regulations. Following the 45 days during which comments on the proposed regulation were sought, the climate action secretariat will complete legal drafting of the regulations, drawing on help from this stakeholder input, and the regulation will subsequently be implemented. An accompanying response form was attached to this consultation paper.

    A 40 watt experimental solar array was directly regulated by shorting out appropriate combinations of series and parallel segments of a solar array. Regulation switches were employed to control the array at various set-point voltages between 25 and 40 volts. Regulation to within + or - 0.5 volt was obtained over a range of solar array temperatures and illumination levels as an active load was varied from open circuit to maximum available power. A fourfold reduction in regulation switch power dissipation was achieved with series-parallel regulation as compared to the usual series-only switching for direct solar array regulation.

    2010-01-01

    Most states regulate abortion differently than other health care services. Examples of these regulations include mandating waiting periods and the provision of state-authored information, and prohibiting private and public insurance coverage for abortion. The primary purpose of this paper is to explore abortion patients' perspectives on these regulations. We recruited 20 participants from three abortion providing facilities located in two states in the U.S. South and Midwest. Using a survey and semistructured interview, we collected information about women's knowledge of abortion regulation and policy preferences. During the interviews, women weighed the pros and cons of abortion regulations. We used grounded theory analytical techniques and matrix analysis to organize and interpret the data. We discovered five themes in these women's considerations of regulation: responsibility, empathy, safe and accessible health care, privacy, and equity. Women in the study generally supported policies that they felt protected women or informed decisions. However, most women also opposed laws mandating two-day abortion appointments for women who were traveling long distances. Women tended to favor financial coverage of abortion, arguing that it could help poor women afford abortion or reduce state expenditures. Overall the study participants' opinions on abortion policy reflect key values for advocates and policy makers to consider: responsibility, empathy, safe and accessible health care, privacy, and equity. Future work should examine abortion regulations in light of these shared values. Laws that promote misinformation or prohibit accommodations of unique circumstances are not consistent the positions articulated by the subjects in our study.

    Full Text Available The current study investigated the interactive effects of individual differences in automatic emotion regulation (AER and primed emotion regulation strategy on skin conductance level (SCL and heart rate during provoked anger. The study was a 2 × 2 [AER tendency (expression vs. control × priming (expression vs. control] between subject design. Participants were assigned to two groups according to their performance on an emotion regulation-IAT (differentiating automatic emotion control tendency and automatic emotion expression tendency. Then participants of the two groups were randomly assigned to two emotion regulation priming conditions (emotion control priming or emotion expression priming. Anger was provoked by blaming participants for slow performance during a subsequent backward subtraction task. In anger provocation, SCL of individuals with automatic emotion control tendencies in the control priming condition was lower than of those with automatic emotion control tendencies in the expression priming condition. However, SCL of individuals with automatic emotion expression tendencies did no differ in the automatic emotion control priming or the automatic emotion expression priming condition. Heart rate during anger provocation was higher in individuals with automatic emotion expression tendencies than in individuals with automatic emotion control tendencies regardless of priming condition. This pattern indicates an interactive effect of individual differences in AER and emotion regulation priming on SCL, which is an index of emotional arousal. Heart rate was only sensitive to the individual differences in AER, and did not reflect this interaction. This finding has implications for clinical studies of the use of emotion regulation strategy training suggesting that different practices are optimal for individuals who differ in AER tendencies.

  17. Evolutionary Plasticity of AmrZ Regulation in Pseudomonas

    Science.gov (United States)

    Dougherty, Kevin; Diaz, Beatriz; Murillo, Rachel

    2018-01-01

    ABSTRACT amrZ encodes a master regulator protein conserved across pseudomonads, which can be either a positive or negative regulator of swimming motility depending on the species examined. To better understand plasticity in the regulatory function of AmrZ, we characterized the mode of regulation for this protein for two different motility-related phenotypes in Pseudomonas stutzeri. As in Pseudomonas syringae, AmrZ functions as a positive regulator of swimming motility within P. stutzeri, which suggests that the functions of this protein with regard to swimming motility have switched at least twice across pseudomonads. Shifts in mode of regulation cannot be explained by changes in AmrZ sequence alone. We further show that AmrZ acts as a positive regulator of colony spreading within this strain and that this regulation is at least partially independent of swimming motility. Closer investigation of mechanistic shifts in dual-function regulators like AmrZ could provide unique insights into how transcriptional pathways are rewired between closely related species. IMPORTANCE Microbes often display finely tuned patterns of gene regulation across different environments, with major regulatory changes controlled by a small group of “master” regulators within each cell. AmrZ is a master regulator of gene expression across pseudomonads and can be either a positive or negative regulator for a variety of pathways depending on the strain and genomic context. Here, we demonstrate that the phenotypic outcomes of regulation of swimming motility by AmrZ have switched at least twice independently in pseudomonads, so that AmrZ promotes increased swimming motility in P. stutzeri and P. syringae but represses this phenotype in Pseudomonas fluorescens and Pseudomonas aeruginosa. Since examples of switches in regulatory mode are relatively rare, further investigation into the mechanisms underlying shifts in regulator function for AmrZ could provide unique insights into the

  18. cDREM: inferring dynamic combinatorial gene regulation.

    Genes are often combinatorially regulated by multiple transcription factors (TFs). Such combinatorial regulation plays an important role in development and facilitates the ability of cells to respond to different stresses. While a number of approaches have utilized sequence and ChIP-based datasets to study combinational regulation, these have often ignored the combinational logic and the dynamics associated with such regulation. Here we present cDREM, a new method for reconstructing dynamic models of combinatorial regulation. cDREM integrates time series gene expression data with (static) protein interaction data. The method is based on a hidden Markov model and utilizes the sparse group Lasso to identify small subsets of combinatorially active TFs, their time of activation, and the logical function they implement. We tested cDREM on yeast and human data sets. Using yeast we show that the predicted combinatorial sets agree with other high throughput genomic datasets and improve upon prior methods developed to infer combinatorial regulation. Applying cDREM to study human response to flu, we were able to identify several combinatorial TF sets, some of which were known to regulate immune response while others represent novel combinations of important TFs.

  2. Self-regulation and selective exposure: the impact of depleted self-regulation resources on confirmatory information processing.

    Science.gov (United States)

    Fischer, Peter; Greitemeyer, Tobias; Frey, Dieter

    2008-03-01

    In the present research, the authors investigated the impact of self-regulation resources on confirmatory information processing, that is, the tendency of individuals to systematically prefer standpoint-consistent information to standpoint-inconsistent information in information evaluation and search. In 4 studies with political and economic decision-making scenarios, it was consistently found that individuals with depleted self-regulation resources exhibited a stronger tendency for confirmatory information processing than did individuals with nondepleted self-regulation resources. Alternative explanations based on processes of ego threat, cognitive load, and mood were ruled out. Mediational analyses suggested that individuals with depleted self-regulation resources experienced increased levels of commitment to their own standpoint, which resulted in increased confirmatory information processing. In sum, the impact of ego depletion on confirmatory information search seems to be more motivational than cognitive in nature.

    2012-04-01

    Radioactive wastes are generated during nuclear fuel cycle operation, production and application of radioisotope in medicine, industry, research, and agriculture, and as a by product of natural resource exploitation, which includes mining and processing of ores. To ensure the protection of human health and the environment from the hazard of these wastes, a planned integrated radioactive waste management practice should be applied. The purpose of this study is to develop regulations for radioactive waste management for low and intermediate radioactive level waste (LILW), and other purpose of regulations is to establish requirements with which all organizations must comply in Sudan from LILW in particular disused/spent sources, not including radioactive waste for milling and mining practices. The national regulations regarding the radioactive waste management, should prescribe the allocation of responsibilities and roles of the Country, the regulatory body, user/owner, waste management organization, including regulations on transport packaging of waste and applied a quality assurance programme, to ensure that radioactive waste management is done safely and securely.

    2015-11-01

    Fatty acid and fat synthesis in the liver is a highly regulated metabolic pathway that is important for very low-density lipoprotein (VLDL) production and thus energy distribution to other tissues. Having common features at their promoter regions, lipogenic genes are coordinately regulated at the transcriptional level. Transcription factors, such as upstream stimulatory factors (USFs), sterol regulatory element-binding protein 1C (SREBP1C), liver X receptors (LXRs) and carbohydrate-responsive element-binding protein (ChREBP) have crucial roles in this process. Recently, insights have been gained into the signalling pathways that regulate these transcription factors. After feeding, high blood glucose and insulin levels activate lipogenic genes through several pathways, including the DNA-dependent protein kinase (DNA-PK), atypical protein kinase C (aPKC) and AKT-mTOR pathways. These pathways control the post-translational modifications of transcription factors and co-regulators, such as phosphorylation, acetylation or ubiquitylation, that affect their function, stability and/or localization. Dysregulation of lipogenesis can contribute to hepatosteatosis, which is associated with obesity and insulin resistance.

  11. Compliance with air quality regulations

    Steen, D.V.; Tackett, D.L.

    1990-01-01

    Due to the probable passage of Clean Air Act Amendments in 1990, electric utilities throughout the United States are faced with numerous choices to comply with the new acid rain regulations, expected in 1991. The choice of a compliance plan is not a simple task. Every compliance option will be costly. At Ohio Edison, deliberations are quite naturally influenced by past compliance with air quality regulations. This paper discusses compliance with air quality regulations in the 1970's, clean coal technologies and advanced scrubbers, and compliance with air quality regulations in 1995 - 2000. The choice of a compliance strategy for many utilities will involve serving customer loads through some combination of scrubbers, clean coal technologies, fuel switching, fuel blending, redispatch of units, and emissions trading. Whatever the final choice, it must be economic while providing sufficient flexibility to accommodate the critical uncertainties of load growth, state regulatory treatment, markets for emission allowances, advancements in control technologies, additional federal requirements for air emissions, equipment outages and fuel supply disruptions.s

    Regulated cellular metabolism has emerged as a fundamental process controlling macrophage functions, but there is still much to uncover about the precise signaling mechanisms involved. Lysine acetylation regulates the activity, stability, and/or localization of metabolic enzymes, as well as inflammatory responses, in macrophages. Two protein families, the classical zinc-dependent histone deacetylases (HDACs) and the NAD-dependent HDACs (sirtuins, SIRTs), mediate lysine deacetylation. We describe here mechanisms by which classical HDACs and SIRTs directly regulate specific glycolytic enzymes, as well as evidence that links these protein deacetylases to the regulation of glycolysis-related genes. In these contexts, we discuss HDACs and SIRTs as key control points for regulating immunometabolism and inflammatory outputs from macrophages. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Recent attempts to improve the healthfulness of away-from-home eating include regulations requiring restaurants to post nutrition information. The impact of such regulations on restaurant environments is unknown. To examine changes in restaurant environments from before to after nutrition-labeling regulation in a newly regulated county versus a nonregulated county. Using the Nutrition Environment Measures Survey-Restaurant version audit, environments within the same quick-service chain restaurants were evaluated in King County (regulated) before and 6 and 18 months after regulation enforcement and in Multnomah County (nonregulated) restaurants over a 6-month period. Data were collected in 2008-2010 and analyses conducted in 2011. Overall availability of healthy options and facilitation of healthy eating did not increase differentially in King County versus Multnomah County restaurants aside from the substantial increase in onsite nutrition information posting in King County restaurants required by the new regulation. Barriers to healthful eating decreased in King County relative to Multnomah County restaurants, particularly in food-oriented establishments. King County restaurants demonstrated modest increases in signage that promotes healthy eating, although the frequency of such promotion remained low, and the availability of reduced portions decreased in these restaurants. The healthfulness of children's menus improved modestly over time, but not differentially by county. A restaurant nutrition-labeling regulation was accompanied by some, but not uniform, improvements in other aspects of restaurant environments in the regulated compared to the nonregulated county. Additional opportunities exist for improving the healthfulness of away-from-home eating beyond menu labeling. Copyright © 2012 American Journal of Preventive Medicine. Published by Elsevier Inc.

    Beside new Ordinance on the control of nuclear material and special equipment ('Official Gazette' No. 15/08), from 2006 State Office for Nuclear Safety (SONS) adopted Ordinance on performing nuclear activities ('Official Gazette' No. 74/06) and Ordinance on special requirements which expert organizations must fulfil in order to perform certain activities in the field of nuclear safety ('Official Gazette' No. 74/06), based on Nuclear Safety Act ('Official Gazette' No. 173/03). The Ordinance on performing nuclear activities regulates the procedure of notification of the intent to perform nuclear activities, submitting the application for the issue of a licence to perform nuclear activities, and the procedure for issuing decisions on granting a licence to perform a nuclear activity. The Ordinance also regulates the content of the forms for notification of the intent to perform nuclear activities, as well as of the application for the issue of a licence to perform the nuclear activity and the method of keeping the register of nuclear activities. According to the Nuclear Safety Act, nuclear activities are the production, processing, use, storage, disposal, transport, import, export, possession or other handling of nuclear material or specified equipment. The Ordinance on special requirements which expert organizations must fulfil in order to perform certain activities in the field of nuclear safety regulates these mentioned conditions, whereas compliance is established by a decision passed by the SONS. Special requirements which expert organizations must fulfil in order to perform certain activities in the field of nuclear safety are organizational, technical, technological conditions and established system of quality assurance. In 2007, State Office for Nuclear Safety finalized the text of new Ordinance on conditions for nuclear safety and protection with regard to the siting, design, construction, use and decommissioning of a facility in which a nuclear activity is

    1990-01-01

    During late 1984 the IAEA Regulations were identified as an area of application for an expert system adviser which could offer many advantages. Over the following year some simple tests were carried out to examine its feasibility, but TRANAID did not get underway until 1986 when British Nuclear Fuels (BNFL) Corporate Management services were engaged on the product. By this time a greater choice of suitable software, in the form of expert system shells, had become available. After a number of trial systems the shell Leonardo was finally adopted for the final system. In order for TRANAID to emulate the expert it was necessary to spend time extracting and documenting the expert knowledge. This was a matter of investigating how the regulations are used and was achieved by a series of meetings including opportunity for the computer specialists to interview the regulations experts. There are several benefits in having an expert system advisor in this area. It is useful to both experienced and inexperienced users of regulations. For those who are learning to use the regulations it is an excellent training aid. For those who know the regulations but use them infrequently it can save time and provide a valuable reassurance. The adviser has enabled the expert user's know how to be captured and to be made widely available to those with less experience. (author)

    Depressed patients suffer from an impairment to voluntarily influence and regulate their unpleasant emotional state. Strengthening the mental ability to interfere with dysfunctional emotion processing may be beneficial in treating depression. According to models of emotion processing this may be done by successful down-regulation of enhanced amygdala activity. We investigated short periods of intentional emotion-introspection compared with cognitive self-reflection as two domains of self-awareness in terms of effects on emotion regulation. Thirty depressed patients performed twelve second periods of emotion-introspection, self-reflection and a neutral condition during functional magnetic resonance imaging. We analyzed brain activation in the patients with depression by means of whole brain, region of interest and connectivity analyses. Amygdala activity decreased during emotion-introspection relative to self-reflection and to the neutral condition, whereby left amygdala was inversely activated relative to the left insula. Insula activity itself was correlated with medial and dorsolateral prefrontal cortex (PFC) activation. In conclusion, depressed patients are able to down-regulate amygdala activity by emotion-introspection. This may be interpreted as well-working emotion regulation supposedly induced by PFC connections mediated via insula. The finding supports the application of emotion-introspection, a mindfulness-related process, in a clinical setting as an element of psychotherapy to train and improve emotion regulation.

  10. Modernising medical regulation: where are we now?

    Science.gov (United States)

    Waring, Justin; Dixon-Woods, Mary; Yeung, Karen

    2010-01-01

    This paper aims to outline and comment on the changes to medical regulation in the UK that provide the background to a special issue of the Journal of Health Organization and Management on regulating doctors. This paper takes the form of a review. Although the UK medical profession enjoyed a remarkably stable regulatory structure for most of the first 150 years of its existence, it has undergone a striking transformation in the last decade. Its regulatory form has mutated from one of state-sanctioned collegial self-regulation to one of state-directed bureaucratic regulation. The erosion of medical self-regulation can be attributed to: the pressures of market liberalisation and new public management reforms; changing ideologies and public attitudes towards expertise and risk; and high profile public failures involving doctors. The "new" UK medical regulation converts the General Medical Council into a modern regulator charged with implementing policy, and alters the mechanisms for controlling and directing the conduct and performance of doctors. It establishes a new set of relationships between the medical profession and the state (including its agencies), the public, and patients. This paper adds to the literature by identifying the main features of the reforms affecting the medical profession and offering an analysis of why they have taken place.

  11. Does drug price-regulation affect healthcare expenditures?

    2017-09-01

    Increasing health costs in developed countries are a major concern for decision makers. A variety of cost containment tools are used to control this trend, including maximum price regulation and reimbursement methods for health technologies. Information regarding expenditure-related outcomes of these tools is not available. To evaluate the association between different cost-regulating mechanisms and national health expenditures in selected countries. Price-regulating and reimbursement mechanisms for prescription drugs among OECD countries were reviewed. National health expenditure indices for 2008-2012 were extracted from OECD statistical sources. Possible associations between characteristics of different systems for regulation of drug prices and reimbursement and health expenditures were examined. In most countries, reimbursement mechanisms are part of publicly financed plans. Maximum price regulation is composed of reference-pricing, either of the same drug in other countries, or of therapeutic alternatives within the country, as well as value-based pricing (VBP). No association was found between price regulation or reimbursement mechanisms and healthcare costs. However, VBP may present a more effective mechanism, leading to reduced costs in the long term. Maximum price and reimbursement mechanism regulations were not found to be associated with cost containment of national health expenditures. VBP may have the potential to do so over the long term.

    Abstract BACKGROUND AND OBJECTIVES: Individuals with social anxiety disorder have often been considered inflexible in their emotion regulation. The aim of this study was to investigate emotion regulation flexibility in socially anxious individuals in response to two contextual factors, namely...... different levels of emotion intensity and emotion type. METHODS: A daily diary approach was employed, investigating emotion regulation (i.e., experiential avoidance, expressive suppression and cognitive reappraisal) in college students scoring high (N = 62; HSA) and low (N = 52; LSA) on social anxiety....... RESULTS: Results revealed that HSAs were found to use more experiential avoidance than LSAs, especially at higher levels of negative intensity. The use of this emotion regulation strategy appeared to be driven by guilt, nervousness, and sadness. There were no between-group differences concerning the other...

  18. Regulation of Adult CNS Axonal Regeneration by the Post-transcriptional Regulator Cpeb1

    2018-01-01

    Full Text Available Adult mammalian central nervous system (CNS neurons are unable to regenerate following axonal injury, leading to permanent functional impairments. Yet, the reasons underlying this regeneration failure are not fully understood. Here, we studied the transcriptome and translatome shortly after spinal cord injury. Profiling of the total and ribosome-bound RNA in injured and naïve spinal cords identified a substantial post-transcriptional regulation of gene expression. In particular, transcripts associated with nervous system development were down-regulated in the total RNA fraction while remaining stably loaded onto ribosomes. Interestingly, motif association analysis of post-transcriptionally regulated transcripts identified the cytoplasmic polyadenylation element (CPE as enriched in a subset of these transcripts that was more resistant to injury-induced reduction at the transcriptome level. Modulation of these transcripts by overexpression of the CPE binding protein, Cpeb1, in mouse and Drosophila CNS neurons promoted axonal regeneration following injury. Our study uncovered a global evolutionarily conserved post-transcriptional mechanism enhancing regeneration of injured CNS axons.

    2015-07-03

    Recent research developments have revealed that caspase-dependent apoptosis is not the sole form of regulated cell death. Caspase-independent, but genetically regulated, forms of cell death include pyroptosis, necroptosis, parthanatos, and the recently discovered ferroptosis and autosis. Importantly, regulated necrosis can be modulated by small molecule inhibitors/activators, confirming the cell autonomous mechanism of these forms of cell death. The success of small molecule-mediated manipulation of regulated necrosis has produced great changes in the field of cell death research, and has also brought about significant changes in the fields of pharmacology as well as toxicology. In this review, we intend to summarize the modes of regulated cell death other than apoptosis, and discuss their implications in toxicology. Copyright © 2015 Elsevier Ireland Ltd.

    Effective regulation of negative affective states has been associated with mental health. Impaired regulation of negative affect represents a risk factor for dysfunctional coping mechanisms such as drug use and thus could contribute to the initiation and development of problematic substance use. This study investigated behavioral and neural indices of emotion regulation in regular marijuana users (n = 23) and demographically matched nonusing controls (n = 20) by means of an fMRI cognitive emotion regulation (reappraisal) paradigm. Relative to nonusing controls, marijuana users demonstrated increased neural activity in a bilateral frontal network comprising precentral, middle cingulate, and supplementary motor regions during reappraisal of negative affect (P marijuana users relative to controls. Together, the present findings could reflect an unsuccessful attempt of compensatory recruitment of additional neural resources in the context of disrupted amygdala-prefrontal interaction during volitional emotion regulation in marijuana users. As such, impaired volitional regulation of negative affect might represent a consequence of, or risk factor for, regular marijuana use.

    Nuclear regulation and safety are discussed from the standpoint of a hypothetical country that is in the process of introducing a nuclear power industry and setting up a regulatory system. The national policy is assumed to be in favor of nuclear power. The regulators will have responsibility for economic, reliable electric production as well as for safety. Reactor safety is divided into three parts: shut it down, keep it covered, take out the afterheat. Emergency plans also have to be provided. Ways of keeping the core covered with water are discussed

  13. Reconstructing a Network of Stress-Response Regulators via Dynamic System Modeling of Gene Regulation

    Directory of Open Access Journals (Sweden)

    Wei-Sheng Wu

    2008-01-01

    Full Text Available Unicellular organisms such as yeasts have evolved mechanisms to respond to environmental stresses by rapidly reorganizing the gene expression program. Although many stress-response genes in yeast have been discovered by DNA microarrays, the stress-response transcription factors (TFs that regulate these stress-response genes remain to be investigated. In this study, we use a dynamic system model of gene regulation to describe the mechanism of how TFs may control a gene’s expression. Then, based on the dynamic system model, we develop the Stress Regulator Identification Algorithm (SRIA to identify stress-response TFs for six kinds of stresses. We identified some general stress-response TFs that respond to various stresses and some specific stress-response TFs that respond to one specifi c stress. The biological significance of our findings is validated by the literature. We found that a small number of TFs is probably suffi cient to control a wide variety of expression patterns in yeast under different stresses. Two implications can be inferred from this observation. First, the response mechanisms to different stresses may have a bow-tie structure. Second, there may be regulatory cross-talks among different stress responses. In conclusion, this study proposes a network of stress-response regulators and the details of their actions.

  14. Economic impact of potential NORM regulations

    1995-01-01

    Oil and gas field wastes and sites contaminated with naturally occurring radioactive materials (NORM) have quickly become a focus of substantial attention by regulators both at the state and federal level. Although currently regulated in a number of states, the Environmental Protection Agency (EPA) has indicated a desire to develop federal regulations to address management and disposal of NORM-contaminated wastes. This paper provides a brief overview of current state NORM regulations, currently available technologies for managing and disposing NORM wastes, and the cost of employing these techniques. Based on these characterizations and alternative assumptions about the volume of NORM wastes, four alternative scenarios have been developed to bracket potential future NORM requirements. These scenarios have been used is the basis for an analysis of the potential economic and supply impacts of NORM requirements on the U.S. oil and gas industry. The results illustrate that a reasonable approach to regulation that focuses only on those NORM wastes that pose a risk and allows producers to use safe, low cost disposal methods (downhole or other) would have minimal economic impacts on the oil and gas industry. A very stringent regulatory approach that covered large volumes of wastes, required the use of higher cost disposal techniques, and required extensive site clean-up activities could have a substantial economic impact, resulting in a loss of up to 20 percent of U.S. oil production and 8 percent of U.S. gas production by 2000. The costs of compliance with these alternative approaches could range from $71 million to over $14 billion annually. Between these two cases lies the opportunity for regulators to develop requirements for management and disposal of NORM wastes that will address any environmental and human health risks posed at industry sites without imposing unnecessarily costly regulations on the U.S. oil and gas E ampersand P industry

  15. Factors that regulate embryonic gustatory development

    Directory of Open Access Journals (Sweden)

    Krimm Robin F

    2007-09-01

    Full Text Available Abstract Numerous molecular factors orchestrate the development of the peripheral taste system. The unique anatomy/function of the taste system makes this system ideal for understanding the mechanisms by which these factors function; yet the taste system is underutilized for this role. This review focuses on some of the many factors that are known to regulate gustatory development, and discusses a few topics where more work is needed. Some attention is given to factors that regulate epibranchial placode formation, since gustatory neurons are thought to be primarily derived from this region. Epibranchial placodes appear to arise from a pan-placodal region and a number of regulatory factors control the differentiation of individual placodes. Gustatory neuron differentiation is regulated by a series of transcription factors and perhaps bone morphongenic proteins (BMP. As neurons differentiate, they also proliferate such that their numbers exceed those in the adult, and this is followed by developmental death. Some of these cell-cycling events are regulated by neurotrophins. After gustatory neurons become post-mitotic, axon outgrowth occurs. Axons are guided by multiple chemoattractive and chemorepulsive factors, including semaphorins, to the tongue epithelium. Brain derived neurotrophic factor (BDNF, functions as a targeting factor in the final stages of axon guidance and is required for gustatory axons to find and innervate taste epithelium. Numerous factors are involved in the development of gustatory papillae including Sox-2, Sonic hedge hog and Wnt-β-catenin signaling. It is likely that just as many factors regulate taste bud differentiation; however, these factors have not yet been identified. Studies examining the molecular factors that regulate terminal field formation in the nucleus of the solitary tract are also lacking. However, it is possible that some of the factors that regulate geniculate ganglion development, outgrowth, guidance and

    Grid infrastructure managers worldwide are facing demands for reinvestments in new assets with higher on-grid and off-grid functionality in order to meet new environmental targets. The roles of the current actors will change as the vertical interfaces between regulated and unregulated tasks become blurred. In this paper, we characterize some of the effects of new asset investments policy on the network tasks, assets and costs and contrast this with the assumptions of the current economic network regulation. To provide structure, we present a model of investment provision under regulation between a distribution system operator and a potential investor–generator. The results from the model confirm the hypothesis that network regulation should find a focal point, should integrate externalities in the performance assessment and should avoid wide delegation of contracting-billing for smart-grid investments. - Highlights: ► We review regulatory solutions for smart-grid and DER investments. ► What matters more than upfront incentives is organization and delegation. ► We model regulated investment under private information by a generator or a DSO. ► Highest welfare for high-powered incentives and centralized information. ► Market approaches likely to give poor outcomes for this case.

  18. Risk-based regulation: A regulatory perspective

    International Nuclear Information System (INIS)

    Scarborough, J.C.

    1993-01-01

    In the early development of regulations for nuclear power plants, risk was implicitly considered through qualitative assessments and engineering reliability principles and practices. Examples included worst case analysis, defense in depth, and the single failure criterion. However, the contributions of various systems, structures, components and operator actions to plant safety were not explicitly assessed since a methodology for this purpose had not been developed. As a consequence of the TMI accident, the use of more quantitative risk methodology and information in regulation such as probabilistic risk analysis (PRA) increased. The use of both qualitative and quantitative consideration of risk in regulation has been a set of regulations and regulatory guides and practices that ensure adequate protection of public health and safety. Presently, the development of PRA techniques has developed to the point that safety goals, expressed in terms of risk, have been established to help guide further regulatory decision making. This paper presents the personal opinions of the author as regards the use of risk today in nuclear power plant regulation, areas of further information needs, and necessary plans for moving toward a more systematic use of risk-based information in regulatory initiatives in the future

The Ordinance on performing nuclear activities regulates the procedure of announcing the intention to perform nuclear activity, submitting an application for the issue of a license to perform nuclear activity, and the procedure for adoption a decision on issuing a nuclear activity license. The Ordinance also regulates the contents of the application form for the announcement of the intention to perform nuclear activity, as well as of the application for the issue of a nuclear activity license and the method of keeping a nuclear activity register. The Ordinance on special conditions for individual activities to be performed by expert organizations which perform activities in the area of nuclear safety regulates these mentioned conditions, whereas compliance is established by a decision passed by the SONS. Special conditions for individual activities to be performed by expert organizations which perform activities in the area of nuclear safety are organizational, technical, technological conditions and established system of quality assurance. In 2007, SONS finalized the text of new Ordinance on nuclear safety and protection conditions for location, design, construction, operation and decommissioning of facility in which nuclear activity is performed. This Ordinance regulates nuclear safety and protection conditions for location, design, construction, operation and decommissioning of facility in which nuclear activity is performed.

    To avoid iterative development of core modules in water resource normal regulation and emergency regulation and improve the capability of maintenance and optimization upgrading of regulation models and business logics, a general water resources regulation software framework was developed based on the collection and analysis of common demands for water resources regulation and emergency management. It can provide a customizable, secondary developed and extensible software framework for the three-level platform "MWR-Basin-Province". Meanwhile, this general software system can realize business collaboration and information sharing of water resources regulation schemes among the three-level platforms, so as to improve the decision-making ability of national water resources regulation. There are four main modules involved in the general software system: 1) A complete set of general water resources regulation modules allows secondary developer to custom-develop water resources regulation decision-making systems; 2) A complete set of model base and model computing software released in the form of Cloud services; 3) A complete set of tools to build the concept map and model system of basin water resources regulation, as well as a model management system to calibrate and configure model parameters; 4) A database which satisfies business functions and functional requirements of general water resources regulation software can finally provide technical support for building basin or regional water resources regulation models.

    Poor self-regulation (i.e., inability to harness cognitive, emotional, motivational resources to achieve goals) is hypothesized to contribute to unhealthy behaviors across the lifespan. Enhancing early self-regulation may increase positive health outcomes. Obesity is a major public health concern with early-emerging precursors related to self-regulation; it is therefore a good model for understanding self-regulation and health behavior. Preadolescence is a transition when children increase autonomy in health behaviors (e.g., eating, exercise habits), many of which involve self-regulation. This paper presents the scientific rationale for examining self-regulation mechanisms that are hypothesized to relate to health behaviors, specifically obesogenic eating, that have not been examined in children. We describe novel intervention protocols designed to enhance self-regulation skills, specifically executive functioning, emotion regulation, future-oriented thinking, and approach bias. Interventions are delivered via home visits. Assays of self-regulation and obesogenic eating behaviors using behavioral tasks and self-reports are implemented and evaluated to determine feasibility and psychometrics and to test intervention effects. Participants are low-income 9-12 year-old children who have been phenotyped for self-regulation, stress, eating behavior and adiposity through early childhood. Study goals are to examine intervention effects on self-regulation and whether change in self-regulation improves obesogenic eating. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The IAEA has systematic programmes to provide Member States with the guidance, services and training necessary for establishing a legal and regulatory framework, including the planning and implementation of decommissioning. The model regulations provided in this publication cover all aspects of the planning, conduct and termination of the decommissioning of facilities and management of the associated waste, in accordance with the relevant requirements of the IAEA safety standards. They provide a framework for establishing regulatory requirements and conditions of authorization to be incorporated into individual authorizations for the decommissioning of specific facilities. The model regulations also establish criteria to be used for assessing compliance with regulatory requirements. The publication will be of assistance to Member States in appraising the adequacy of their existing regulations and regulatory guides, and serves as a reference for those Member States developing regulations for the first time.

    Governmental regulation of toxic substances, such as carcinogens and radiation, prompts both legal and scientific controversies. Industry, environmental activist groups, government regulators, and the general public are all concerned with the question of how environmental risk to public health is to be measured and what level of risk warrants government action under the environmental laws. Several recent events shed light on the fundamental scientific and legal problems inherent in such regulation, and these events may affect the direction of future developments. These events include implementation of generic Risk Assessment Guidelines by the US EPA, litigation challenging EPA's regulation of carcinogenic substances, new scientific understanding of the relative risks from human exposure to natural and man-made sources, and the continuing growth of toxic tort litigation in which victims of cancer seek large damages from industrial emitters of pollution

    Kim, Chang H

    2018-03-22

    Commensal microbes and the host immune system have been co-evolved for mutual regulation. Microbes regulate the host immune system, in part, by producing metabolites. A mounting body of evidence indicates that diverse microbial metabolites profoundly regulate the immune system via host receptors and other target molecules. Immune cells express metabolite-specific receptors such as P2X 7 , GPR41, GPR43, GPR109A, aryl hydrocarbon receptor precursor (AhR), pregnane X receptor (PXR), farnesoid X receptor (FXR), TGR5 and other molecular targets. Microbial metabolites and their receptors form an extensive array of signals to respond to changes in nutrition, health and immunological status. As a consequence, microbial metabolite signals contribute to nutrient harvest from diet, and regulate host metabolism and the immune system. Importantly, microbial metabolites bidirectionally function to promote both tolerance and immunity to effectively fight infection without developing inflammatory diseases. In pathogenic conditions, adverse effects of microbial metabolites have been observed as well. Key immune-regulatory functions of the metabolites, generated from carbohydrates, proteins and bile acids, are reviewed in this article. © 2018 John Wiley & Sons Ltd.

    President Carter issued Executive Order 12044 (3/28/78) that required all Federal agencies to distinguish between significant and insignificant regulations, and to determine whether a regulation will result in major impacts. This study gathered information on the impact of the order and the guidelines on the Office of Conservation and Solar Energy (CS) regulatory practices, investigated problems encountered by the CS staff when implementing the order and guidelines, and recommended solutions to resolve these problems. Major tasks accomplished and discussed are: (1) legislation, Executive Orders, and DOE Memoranda concerning Federal administrative procedures relevant to the development and analysis of regulations within CS reviewed; (2) relevant DOE Orders and Memoranda analyzed and key DOE and CS staff interviewed in order to accurately describe the current CS regulatory process; (3) DOE staff from the Office of the General Counsel, the Office of Policy and Evaluation, the Office of the Environment, and the Office of the Secretary interviewed to explore issues and problems encountered with current CS regulatory practices; (4) the regulatory processes at five other Federal agencies reviewed in order to see how other agencies have approached the regulatory process, dealt with specific regulatory problems, and responded to the Executive Order; and (5) based on the results of the preceding four tasks, recommendations for potential solutions to the CS regulatory problems developed.

    Full Text Available Self-regulation and self-regulated learning (SRL are important features in music education. In this research self-regulated learning model is presented as a complex, multidimensional structure. SRL starts with the self-regulation. Self-regulation is formed through interaction with the environment, thus self-learning, self-analysis, self-judgment, self-instruction, and self-monitoring are the main functions in self-regulatory structure. Co-regulation is needed, and helps self-regulation to be activated and monitored. In music education, co-regulation refers to the instructions that teacher introduces in the lessons. These instructions have to enhance learning and develop regulation over emotions, cognitive, auditor, and motor skills in students. Learning techniques and learning strategies are core components in music education. Adapting those, students become aware of their learning processes, actions, thoughts, feelings and behaviors that are involved in learning. It is suggested that every teaching methodology has to develop learning techniques, as well as metamemory and metacognition in students, in order to gain expertise. The author has emphasized her attention to every aspect that is believed to belong to SRL. There are not many articles on the SRL in music education, written by musicians, in compare with those written by psychologists and neurologists,. Therefore, the author has suggested that this paper would encourage music teachers and performers to take an advantage in the research of SRL. These researches would help music educational systems and teachers to develop and promote learning techniques and strategies. The results would show improvement in student’s learning and self-regulation.

    Full Text Available The Biocidal Products Regulation (BPR contains several provisions for nanomaterials (NMs and is the first regulation in the European Union to require specific testing and risk assessment for the NM form of a biocidal substance as a part of the information requirements. Ecotoxicological data are one of the pillars of the information requirements in the BPR, but there are currently no standard test guidelines for the ecotoxicity testing of NMs. The overall objective of this work was to investigate the implications of the introduction of nano-specific testing requirements in the BPR and to explore how these might be fulfilled in the case of copper oxide nanoparticles. While there is information and data available in the open literature that could be used to fulfill the BPR information requirements, most of the studies do not take the Organisation for Economic Co-operation and Development’s nanospecific test guidelines into consideration. This makes it difficult for companies as well as regulators to fulfill the BPR information requirements for nanomaterials. In order to enable a nanospecific risk assessment, best practices need to be developed regarding stock suspension preparation and characterization, exposure suspensions preparation, and for conducting ecotoxicological test.

  13. Progress toward risk informed regulation

    Rogers, K.C.

    1997-01-01

    For the last several years, the NRC, with encouragement from the industry, has been moving in the direction of risk informed regulation. This is consistent with the regulatory principle of efficiency, formally adopted by the Nuclear Regulatory Commission in 1991, which requires that regulatory activities be consistent with the degree of risk reduction they achieve. Probabilistic risk analysis has become the tool of choice for selecting the best of several alternatives. Closely related to risk informed regulation is the development of performance based rules. Such rules focus on the end result to be achieved. They do not specify the process, but instead establish the goals to be reached and how the achievement of those goals is to be judged. The inspection and enforcement activity is based on whether or not the goals have been met. The author goes on to offer comments on the history of the development of this process and its probable development in the future. He also addresses some issues which must be resolved or at least acknowledged. The success of risk informed regulation ultimately depends on having sufficiently reliable data to allow quantification of regulatory alternatives in terms of relative risk. Perhaps the area of human reliability and organizational performance has the greatest potential for improvement in reactor safety. The ability to model human performance is significantly less developed that the ability to model mechanical or electrical systems. The move toward risk informed, performance based regulation provides an unusual, perhaps unique, opportunity to establish a more rational, more effective basis for regulation

    Several cities in Indonesia have the sewerage local regulation such as Banjarmasin, Bantul, Surakarta and Denpasar. Meanwhile, The National Government have guideline in composing domestic sewerage regulation. Each city have their own characteristic and issues that need to be carried out by the local regulation. By using SWOT analysis, this study tries to figure out several aspect that need to be included in the local regulation. International references from developed and developing countries like Japan, Phillipines, Malaysia and Thailand were also used as benchmark without neglecting the local conditions of cities in Indonesia. Several crucial aspect of local regulation are institutional authority, composition on-site and off-site system, tariff, evaluation and monitoring, as well as punishment and rewards. Both tariff and evaluation aspects need to be narrowed down into specific regulations.

    In 1995, hydrographic and chlorofluorocarbon (CFCs, components F11, F12) measurements were carried out in the Gulf of Aden, in the Gulf of Oman, and in the Arabian Sea. In the Gulf of Oman, the F12 concentrations in the Persian Gulf outflow (PGW) at about 300m depth were significantly higher than in ambient surface water with saturations reaching 270%. These high values could not be caused by air-sea gas exchange. The outflow was probably contaminated with oil, and the lipophilic character of...

  16. Greenhouse effect of trace gases, 1970-1980

    Lacis, A.; Hansen, J.; Lee, P.; Lebedeff, S.; Mitchell, T.

    1981-01-01

    Increased abundances were measured for several trace atmospheric gases in the decade 1970-1980. The equilibrium greenhouse warming for the measured increments of CH4, chlorofluorocarbons and N2O is between 50% and 100% of the equilibrium warming for the measured increase of atmospheric CO2 during the same 10 years. The combined warming of CO2 and trace gases should exceed natural global temperature variability in the 1980's and cause the global mean temperature to rise above the maximum of the late 1930's.

  17. N-MYC down-regulated-like proteins regulate meristem initiation by modulating auxin transport and MAX2 expression.

    2013-01-01

    N-MYC down-regulated-like (NDL) proteins interact with the Gβ subunit (AGB1) of the heterotrimeric G protein complex and play an important role in AGB1-dependent regulation of lateral root formation by affecting root auxin transport, auxin gradients and the steady-state levels of mRNA encoding the PIN-FORMED 2 and AUXIN 1 auxin transport facilitators. Auxin transport in aerial tissue follows different paths and utilizes different transporters than in roots; therefore, in the present study, we analyzed whether NDL proteins play an important role in AGB1-dependent, auxin-mediated meristem development. Expression levels of NDL gene family members need to be tightly regulated, and altered expression (both over-expression and down-regulation) confers ectopic growth. Over-expression of NDL1 disrupts vegetative and reproductive organ development. Reduced expression of the NDL gene family members results in asymmetric leaf emergence, twinning of rosette leaves, defects in leaf formation, and abnormal silique distribution. Reduced expression of the NDL genes in the agb1-2 (null allele) mutant rescues some of the abnormal phenotypes, such as silique morphology, silique distribution, and peduncle angle, suggesting that proper levels of NDL proteins are maintained by AGB1. We found that all of these abnormal aerial phenotypes due to altered NDL expression were associated with increases in basipetal auxin transport, altered auxin maxima and altered MAX2 expression within the inflorescence stem. NDL proteins, together with AGB1, act as positive regulators of meristem initiation and branching. AGB1 and NDL1 positively regulate basipetal inflorescence auxin transport and modulate MAX2 expression in shoots, which in turn regulates organ and lateral meristem formation by the establishment and maintenance of auxin gradients.

  2. Naked regulators: moral pluralism, deliberative democracy and authoritative regulation of human embryonic stem cell (hESC) research.

    Science.gov (United States)

    Parker, Malcolm

    2009-02-01

    Bioethical issues pose challenges for pluralist, democratic societies due to the need to arbitrate between incompatible views over fundamental beliefs. The legitimacy of public policy is increasingly seen to depend on taking public consultation seriously, and subsequently regulating contested activities such as therapeutic cloning and hESC research. In December 2006, the Australian Federal Parliament lifted the ban on therapeutic cloning, following recommendations of the Legislation Review Committee (Lockhart Committee), which recently reported on its approach and methods in this journal. This column analyses recent accounts of democratic deliberative processes, authoritative regulation and the committee's own account. Authoritative regulation turns out to be largely an appeasement strategy, directed towards the losers of the contest, in this case the opponents of therapeutic cloning and hESC research. This is because regulation fails to minimise harm as perceived by the losers, and fails to meaningfully limit what it is the winners wish to do. Moreover, regulation adds an unnecessary layer of red tape to the work of the winners. Committees of inquiry in bioethical matters should be more open about their processes and their normative recommendations, at the risk of eroding trust in parts of their processes.

  3. Marketing of food and beverage in Brazil: scientific literature review on regulation and self-regulation of advertisements

    Full Text Available The effects of marketing strategies for promotion of foods and beverages have been investigated due to its potential impacts on populations’ food choices, particularly among children and adolescents. The paper presents an academic literature review on regulation and self-regulation of food and beverage advertisements in Brazil, based on search performed in electronic databases. Majority of studies were based on law analysis or qualitative study of advertisements. There are sufficient evidences on the need for government regulation of advertisements addressed to children and adolescents complementarily to institutional self-regulation in order to tackle ethical transgressions on food and beverage advertisements identified in Brazil. Additionally, there should be imposition of rigorous penalties for noncompliance to ethical rules and proposition of incentives towards actions encouraging healthy food consumption patterns, in order to comprise an actual system for promotion of public health.

    2016-01-01

    Full Text Available Emotion regulation (ER is a basic psychological process that has been broadly linked to psychosocial adjustment. Due to its relationship with psychosocial adjustment, a significant number of instruments have been developed to assess emotion regulation in a reliable and valid manner. Among these, the Emotion Regulation Questionnaire (ERQ; Gross & John, 2003 is one of the most widely used, having shown good psychometric properties with adult samples from different cultures. Studies of validation in children and adolescents are, however, scarce and have only been developed for the Australian and Portuguese populations. The aim of this study was to validate the Spanish version of the ERQ for use in adolescents and determine possible differences according to the gender and age of young people. The sample consisted of 2060 adolescents (52.1% boys. Exploratory and Confirmatory factor analysis (EFA and CFA, multi-group analysis and two-way multivariate analysis of variance (MANOVA were performed and the percentiles calculated. The results of the AFE and CFA corroborated the existence of two factors related to the emotion regulation strategies of cognitive reappraisal and expressive suppression, showing acceptable internal consistency and test-retest reliability. Both factors also showed good criterion validity with personality traits, self-esteem, and social anxiety. Differences in cognitive reappraisal were found with regard to age, with younger students exhibiting the greatest mastery of this strategy. Gender differences were observed regarding the expressive suppression strategy, with boys being more likely to use this strategy than girls. A gender-age interaction effect was also observed, revealing that the use of the expressive suppression strategy did not vary by age in girls, and was more widely used by boys aged 12-14 years than those aged 15-16 years. However, we found evidence of measurement invariance across sex and age groups. The results

    Full Text Available Cybercrime has become a global phenomenon, which is causing more harm to individual citizens, organizations, society and the state. Most countries in the world compare cybercrime with offences such as terrorism and drug trafficking due to its risks and profitability. Cybersecurity is the central category to fight cybercrime in cyberspace. Therefore, the strategic legal regulation of cybersecurity is one of the most relevant problems in EU, including Lithuania. So far cybersecurity legal regulation analysis in scientific literature has been rather limited. The European Commission, together with the High Representative of the Union for Foreign Affairs and Security Policy, has published a cybersecurity strategy alongside a Commission proposed directive on network and information security (NIS. The cybersecurity strategy – “An Open, Safe and Secure Cyberspace” - represents the EU’s comprehensive vision on how best to prevent and respond to cyber disruptions and attacks. The purpose of its is to further European values of freedom and democracy and ensure the digital economy can safely grow. Specific actions are aimed at enhancing cyber resilience of information systems, reducing cybercrime and strengthening EU international cyber-security policy and cyber defence. The main goal of the paper is to analyze and compare the EU cybersecurity strategy and experience of several foreign countries with the strategic legal regulation of cybersecurity in Lithuania. The article consists of four parts. The first part dealt with the EU cybersecurity strategy. The second part of the article examines the comparative aspect of foreign cybersecurity strategic legal regulation. The third part deals with attempts in Lithuania to draft cybersecurity law and the holistic approach of cybersecurity legal regulation. The fourth part examines Lithuanian cybersecurity strategy and comments on the main probleas related with the strategy. Several different approaches

    The NMDA receptor is the most widely studied ionotropic glutamate receptor, and it is central to many physiological and pathophysiological processes in the central nervous system. GluN2A is one of the two main types of GluN2 NMDA receptor subunits in the forebrain. The proper activity of GluN2A is important to brain function, as the abnormal regulation of GluN2A may induce some neuropsychiatric disorders. This review will examine the regulation of GluN2A by endogenous and exogenous regulators in the central nervous system.

    2010-01-01

    Full Text Available The French regulation school sets out to carry out an analysis of Capitalism and its transformations, with the purpose of understanding the periods of stable growth and the moments of structural change. The object of this paper consists of carrying out a critical revision of the contributions of this school, concentrating on the conceptual framework that it has developed. For this, in the first place the influences that marked the regulation approach will be reviewed, with special attention on its recovery from the Marxist tradition. Secondly, the ontological and methodological differences between the regulation approach and the neoclassic economy theory will be highlighted. Thirdly, the fundamental concepts of the regulation school will be examined. In fourth place, it will be seen how, from these concepts, the crisis at the beginning of the 1970s was interpreted. In fifth place, how the regulation approach is thought as to the relation between economy and policy. In sixth place, the question of the international dimension will be examined. Finally, the main objections that have been presented to the regulation approach, will be shown and will be evaluated critically.

  8. Emotions and Behavior Regulation in Decision Dilemmas

    Directory of Open Access Journals (Sweden)

    Joaquin Gómez-Miñambres

    2017-05-01

    Full Text Available We introduce a dynamic model of emotional behavior regulation that can generalize to a wide range of decision dilemmas. Dilemmas are characterized by availability of mutually exclusive goals that a decision maker is dually motivated to pursue. In our model, previous goal pursuant decisions produce negative emotions that regulate an individual’s propensity to further pursue those goals at future times. This emotional regulation of behavior helps explain the non-stationarity and switching observed between so-called “preferences” revealed in repeated decision dilemmas (e.g., by choosing A over B at time 1, then choosing B over A at time 2. We also explain how behavior regulation under dilemma conditions is affected by the set of available options and how the strength and decay rate of emotions affect the tendency to choose behaviors pursuant of extremely (rather than moderately different options over time. We discuss how emotional behavior regulation insights provided by our model can extend to a variety of topics including approach and avoidance, temptation and self-control, moral balancing, impulse buying and shopping momentum, dieting and exercise, work and leisure, sleep regulation, cooperation, and competition.

    Beta cell mass, at any given time, is governed by cell differentiation, neogenesis, increased or decreased cell size (cell hypertrophy or atrophy), cell death (apoptosis), and beta cell proliferation. Nutrients, hormones and growth factors coupled with their signalling intermediates have been...... suggested to play a role in beta cell mass regulation. In addition, genetic mouse model studies have indicated that cyclins and cyclin-dependent kinases that determine cell cycle progression are involved in beta cell replication, and more recently, menin in association with cyclin-dependent kinase...... inhibitors has been demonstrated to be important in beta cell growth. In this review, we consider and highlight some aspects of cell cycle regulation in relation to beta cell replication.

    Bengtsson, G

    1988-07-01

    Decisions to regulate genotoxic substances involve trade-offs between various incomparable factors such as risks to human health and other environmental risks, public perceptions, costs and uncertainties. Two different approaches towards these trade-offs are discussed. In one approach, all relevant factors are defined and trade-offs are considered using a general and very elaborate analysis. Cost-benefit analysis is an exponent of this approach. An illustration is given for the regulation of transboundary releases of radioactive materials. The other approach considers what is politically feasible for the time being and seeks a decision with much room for later corrections. Incrementalism is a philosophy in this vein. It is illustrated by reference to the regulation of transboundary air pollution. Weaknesses and strengths of the two approaches are discussed. (author)

    We empirically investigate the responsiveness of international trade to the stringency of environmental regulation. Stringent environmental regulation may impair the export competitiveness of 'dirty' domestic industries, and as a result, 'pollution havens' emerge in countries where environmental regulation is 'over-lax.' We examine the impact of pollution abatement and control costs on net exports in order to grasp this phenomenon. Theoretically, our analysis is related to a general equilibrium model of trade and pollution nesting the pollution haven motive for trade with the factor endowment motive. We analyze data on two-digit ISIC manufacturing industries during the period 1977-1992 in Germany, the Netherlands and the US, and show that trade patterns in 'dirty' commodities are jointly determined by relative factor endowments and environmental stringency differentials.

    Official attitude towards irradiated food is determined by factors such as: level of scientific knowledge, consumer habits, food shortages, agricultural production and technological know-how. To date, 39 countries have accepted the process for one or more food items while 27 nations carry out the process on a commercial basis. Regulations and codes of practice is essential for consumer confidence while uniformity of regulations, at the international level, will enhance international trade in irradiated food items. The internationally accepted Codex Standard on irradiated food and Codes of Practice for the operation of irradiation facilities, adopted in 1983, forms the basis for International regulations and a template for nations in the development of regulations. This paper discusses the basic legal requirements for licensing the process, procedures, facility and the operator and suggests a framework for a national regulation based on experiences of Hungary, Brazil and Israel

    An important number of newly identified molecular alterations in prostate cancer affect gene encoding master regulators of chromatin biology epigenetic regulation. This review will provide an updated view of the key epigenetic mechanisms underlying prostate cancer progression, therapy resistance, and potential actionable mechanisms and biomarkers. Key players in chromatin biology and epigenetic master regulators has been recently described to be crucially altered in metastatic CRPC and tumors that progress to AR independency. As such, epigenetic dysregulation represents a driving mechanism in the reprograming of prostate cancer cells as they lose AR-imposed identity. Chromatin integrity and accessibility for transcriptional regulation are key features altered in cancer progression, and particularly relevant in nuclear hormone receptor-driven tumors like prostate cancer. Understanding how chromatin remodeling dictates prostate development and how its deregulation contributes to prostate cancer onset and progression may improve risk stratification and treatment selection for prostate cancer patients.

    Like all technologies, nanotechnology will inevitably present risks, whether they result from unintentional effects of otherwise beneficial applications, or from the malevolent misuse of technology. Increasingly, risks from new and emerging technologies are being regulated at the international level, although governments and private experts are only beginning to consider the appropriate international responses to nanotechnology. In this paper, we explore both the potential risks posed by nanotechnology and potential regulatory frameworks that law may impose. In so doing, we also explore the various rationales for international regulation including the potential for cross-boundary harms, sharing of regulatory expertise and resources, controlling protectionism and trade conflicts, avoiding a "race to the bottom" in which governments seek economic advantage through lax regulation, and limiting the "nano divide" between North and South. Finally, we examine some models for international regulation and offer tentative thoughts on the prospects for each.

    With hundreds of chromatin regulators identified in mammals, an emerging issue is how they modulate biological and pathological processes. BRPF1 (bromodomain- and PHD finger-containing protein 1) is a unique chromatin regulator possessing two PHD fingers, one bromodomain and a PWWP domain for recognizing multiple histone modifications. In addition, it binds to the acetyltransferases MOZ, MORF, and HBO1 (also known as KAT6A, KAT6B, and KAT7, respectively) to promote complex formation, restrict substrate specificity, and enhance enzymatic activity. We have recently showed that ablation of the mouse Brpf1 gene causes embryonic lethality at E9.5. Here we present systematic analyses of the mutant animals and demonstrate that the ablation leads to vascular defects in the placenta, yolk sac, and embryo proper, as well as abnormal neural tube closure. At the cellular level, Brpf1 loss inhibits proliferation of embryonic fibroblasts and hematopoietic progenitors. Molecularly, the loss reduces transcription of a ribosomal protein L10 (Rpl10)-like gene and the cell cycle inhibitor p27, and increases expression of the cell-cycle inhibitor p16 and a novel protein homologous to Scp3, a synaptonemal complex protein critical for chromosome association and embryo survival. These results uncover a crucial role of Brpf1 in controlling mouse embryo development and regulating cellular and gene expression programs. PMID:25773539

  1. The significance of translation regulation in the stress response

    Background The stress response in bacteria involves the multistage control of gene expression but is not entirely understood. To identify the translational response of bacteria in stress conditions and assess its contribution to the regulation of gene expression, the translational states of all mRNAs were compared under optimal growth condition and during nutrient (isoleucine) starvation. Results A genome-scale study of the translational response to nutritional limitation was performed in the model bacterium Lactococcus lactis. Two measures were used to assess the translational status of each individual mRNA: the fraction engaged in translation (ribosome occupancy) and ribosome density (number of ribosomes per 100 nucleotides). Under isoleucine starvation, half of the mRNAs considered were translationally down-regulated mainly due to decreased ribosome density. This pattern concerned genes involved in growth-related functions such as translation, transcription, and the metabolism of fatty acids, phospholipids and bases, contributing to the slowdown of growth. Only 4% of the mRNAs were translationally up-regulated, mostly related to prophagic expression in response to stress. The remaining genes exhibited antagonistic regulations of the two markers of translation. Ribosome occupancy increased significantly for all the genes involved in the biosynthesis of isoleucine, although their ribosome density had decreased. The results revealed complex translational regulation of this pathway, essential to cope with isoleucine starvation. To elucidate the regulation of global gene expression more generally, translational regulation was compared to transcriptional regulation under isoleucine starvation and to other post-transcriptional regulations related to mRNA degradation and mRNA dilution by growth. Translational regulation appeared to accentuate the effects of transcriptional changes for down-regulated growth-related functions under isoleucine starvation although m

    The US Environmental Protection Agency (EPA) is currently developing standards for the disposal of low-level radioactive waste (LLW). As part of this Standard, EPA is including regulations for the disposal of naturally occurring and accelerator-produced radioactive material (NARM) wastes not covered under the Atomic Energy Act (AEA). The regulations will cover only higher-activity NARM wastes, defined as NARM waste with specific activity exceeding two nanocuries per gram. The proposed regulations will specify that NARM wastes exceeding the above limits, except for specific exempted items, must be disposed of in regulated radioactive waste disposal facilities. The proposed EPA regulations for NARM wastes will be discussed, as well as the costs and benefits of the regulation, how it will be implemented by EPA, and the rationale for covering only higher-activity NARM wastes exceeding two nanocuries per gram

    The temperature of the APS S-Band linac's high-power rf components is regulated by water from individual closed-loop deionized (DI) water systems. The rf components are all made of oxygen-free high-conductivity copper and respond quickly to temperature changes. The SLED cavities are especially temperature-sensitive and cause beam energy instabilities when the temperature is not well regulated. Temperature regulation better than ± 0.1 F is required to achieve good energy stability. Improvements in the closed-loop water systems have enabled them to achieve a regulation of ± 0.05 F over long periods. Regulation philosophy and equipment are discussed and numerical results are presented

    Government taxation and regulation have a profound influence on mineral operations. In Canada, taxation occurs both on the federal and provincial levels. In addition, both federal and provincial regulations also affect mine operations, sometimes with overlapping, or conflicting, legislation and jurisdiction. Three broad areas of regulation affect the mine production of uranium in Canada: (1) mining law or mineral rights; (2) the licensing procedures; and (3) regulation of occupational health and safety

    The French Space Operation Act(FSOA) stipulates that a prime objective of the National technical regulations is to protect people, property, public health and the environment. Compliance with these technical regulations is mandatory as of 10 December 2010 for space operations by French space operators and for space operations from French territory. The space safety requirements and regulations governing procedures are based on national and international best practices and experience. A critical design review of the space system and procedures shall be carried out by the applicant, in order to verify compliance with the Technical Regulations. An independent technical assessment of the operation is delegated to CNES. The principles applied when drafting technical regulations are as follows: requirements must as far as possible establish the rules according to the objective to be obtained, rather than how it is to be achieved; requirements must give preference to international standards recognised as being the state of the art; requirements must take previous experience into account. Technical regulations are divided into three sections covering common requirements for the launch, control and return of a space object. A dedicated section will cover specific rules to be applied at the Guiana Space Centre. The main topics addressed by the technical regulations are: operator safety management system; study of risks to people, property, public health and the Earth’s environment; impact study on the outer space environment: space debris generated by the operation; planetary protection.

    Both national and international organisations agree that the fundamental objective of all nuclear safety regulatory bodies - the regulator's prime purpose - is to ensure that nuclear licensees operate their facilities at all times in a safe manner. Much has been written about ways to improve regulatory processes or to improve the effectiveness of a regulatory body, including in previous OECD/NEA regulatory guidance booklets. But until now, none have focused on the characteristics of an effective nuclear safety regulator. Effective organisations are those that have good leadership and are able to transform strategic direction into operational programmes. Effectiveness is about how well the organisation is achieving its fundamental purpose - in the case of a nuclear safety regulator, ensuring that licensees operate their facilities and discharge their obligations in a safe manner. This regulatory guidance booklet describes the characteristics of an effective nuclear safety regulator in terms of roles and responsibilities, principles and attributes. Each of the characteristics discussed in this report is a necessary feature of an effective nuclear safety regulator but no one characteristic is sufficient on its own. It is the combination of these characteristics that leads to the effectiveness of a nuclear regulatory body. The report provides a unique resource to countries with existing, mature regulators and can be used for benchmarking as well as training and developing staff. It will also be useful for new entrant countries in the process of developing and maintaining an effective nuclear safety regulator. (authors)

  10. Design of an eight-megawatt series regulator

    DeVore, K.R.

    1977-01-01

    An 8-MW, 100 percent duty cycle, hard tube series regulator used to control the accelerating voltage of a neutral beam source is described. The series tube is a developmental switch/regulator tube capable of holding off 200 kV passing 85 A, and dissipating 2 MW of anode power. The regulator has high-speed interrupt capability to minimize the power delivered to the load in the event of a load fault. Its design is such that it can be used to regulate both positive and negative accelerating voltages. All reference/control signals between the modulator and the control station use optical links to minimize noise interference and ground loop problems. In all cases of optical coupling, the loss of light is the worst-case condition, i.e., loss of light turns off the regulator. The fast interrupt is accomplished by rapid removal of the screen grid voltage from the series tube, and then driving the control grid into cutoff. After the control grid is in cutoff the screen is allowed to recover, and the regulator is then ready to switch back on. The regulator tube driver is a straightforward dc-coupled amplifier with a cathode follower output; dc isolation between various sections of the modulator is accomplished by using optical coupling. The use of optics allows the use of solid-state devices in an extremely hostile environment containing both electromagnetic and nuclear radiation

    The Safe Drinking Water Act amendments of 1996 have imposed new requirements on the US Environmental Protection Agency (USEPA) to establish drinking water regulations. The regulatory process has been revised and now requires the use of sound science. Costs, benefits, and competing risks may also be considered. Current regulations for fluoride, volatile organic chemicals, total coliforms, surface water treatment, Phase 2 and Phase 5 synthetic organic and inorganic contaminants, and lead and copper remain basically unchanged. New deadlines are established for the regulation of arsenic, sulfate, radon, disinfectants and disinfection by-products, enhanced surface water treatment, and groundwater disinfection

    Studies about the effects of aging in the physiology and metabolism are increasingly, one of its objectives is to help implement programs to improve the quality of life and prevent disability in elderly. It is relevant to mention that, during aging, there is a natural metabolic deceleration, a series of changes in the regulation of energy are produced, which contributes to loss of weight and fat; the changes in the regulation of caloric intake contribute to increase the susceptibility to energy imbalance both positive and negative, which is associated with a deterioration in health. However, to grow old, is not a death sentence for metabolism, on the other hand, it can be controlled by maintaining an active lifestyle, coupled with this, research has shown that the metabolism'can be regulated by a synchronized clock (circadian rhythms), which is mediated by regulatory proteins, this relationship ensures the proper functioning of the cells and therefore good health. The aim of this review is to provide updated information on the energy- metabolism-regulation and its relationship with the great variety of components involved in energy expenditure that accompany aging, to analyze the regulation of this system to improve the quality of life and maintenance of health in old age.

  14. Transcription regulation by the Mediator complex.

    2018-04-01

    Alterations in the regulation of gene expression are frequently associated with developmental diseases or cancer. Transcription activation is a key phenomenon in the regulation of gene expression. In all eukaryotes, mediator of RNA polymerase II transcription (Mediator), a large complex with modular organization, is generally required for transcription by RNA polymerase II, and it regulates various steps of this process. The main function of Mediator is to transduce signals from the transcription activators bound to enhancer regions to the transcription machinery, which is assembled at promoters as the preinitiation complex (PIC) to control transcription initiation. Recent functional studies of Mediator with the use of structural biology approaches and functional genomics have revealed new insights into Mediator activity and its regulation during transcription initiation, including how Mediator is recruited to transcription regulatory regions and how it interacts and cooperates with PIC components to assist in PIC assembly. Novel roles of Mediator in the control of gene expression have also been revealed by showing its connection to the nuclear pore and linking Mediator to the regulation of gene positioning in the nuclear space. Clear links between Mediator subunits and disease have also encouraged studies to explore targeting of this complex as a potential therapeutic approach in cancer and fungal infections.

    2014-01-01

    The purpose of this paper is to explore approaches to the regulation of healthcare complaints and disciplinary processes. A literature review was conducted across Medline, Sociological Abstracts, Web of Science, Google Scholar and the health, law and social sciences collections of Informit, using terms tapping both the complaints process and regulation generally. A total of 118 papers dealing with regulation of health complaints or disciplinary proceedings were located. The review reveals a shift away from self-regulation towards greater external oversight, including innovative regulatory approaches including "networked governance and flexible or "responsive" regulation. It reports growing interest in adoption of strategic and responsive approaches to health complaints governance, by rejecting traditional legal forms in favor of more strategic and responsive forms, taking account of the complexity of adverse health events by tailoring responses to individual circumstances of complainants and their local environments. The challenge of how to collect and harness complaints data to improve the quality of healthcare at a systemic level warrants further research. Scope also exists for researching health complaints commissions and other "meta-regulatory" bodies to explore how to make these processes fairer and better able to meet the complex needs of complainants, health professionals, health services and society.

    This report is about the design of economic regulation of electricity companies in the Nordic countries. The purpose is to inform the interested reader on how the regulation of tariffs is designed. The intention is to give a short overview on the current economic regulation with an ambition to focus on differences and similarities. A common feature of the electricity distribution sector is that the industry structure consists of many independent companies with great differences in size and density of customers. This is contrary to what is common in other countries. The regulatory task can be more challenging with many separate utilities to regulate, especially if the industry is very heterogenous. In the appendices, the economic regulation of each country is presented in more detail. In the main text the focus is on differences and similarities. When comparing the regulations one can make two observations. On a superior level there are great similarities. All Nordic countries regulate the network companies by setting revenue caps. The legislation, the goals given to the regulators and the regulators general interpretation of the rules are to a great extent the same. The primary purposes are to prevent the monopolist to overcharge customers and to create a rational network industry. The regulation shall stimulate an effective management resulting in productivity development and optimal quality of the services. The differences in the Nordic economic regulations are in the details - in the setup of the regulatory models and choice of parameters. For instance; the assessment of a reasonable rate-of-return is done in all the regulations. When deciding this rate-of-return some countries use the method of weighted cost of capital (WACC) and capital asset pricing model (CAPM), other do not. Even when using the same method, the inputs in the model are not the same. Common for the regulatory models are the division of costs related to capital costs and operating costs. The
