  2. Efficiency of European emissions markets: Lessons and implications

    Krishnamurti, Chandrasekhar; Hoque, Ariful

    2011-01-01

    While prior studies have shown that emission rights and futures contracts on emission rights are efficiently priced, there are no studies on the efficiency of the options market. Therefore, this study fills the gap. We examine empirical evidence regarding the efficiency of the options market for emissions rights in Europe. We employ the put-call parity approach to test the efficiency of options on emission rights traded in the European market. This implies that firms can trade options on emission rights in addition to other existing strategies in order to manage their greenhouse gas emissions. - Highlights: → Efficiency of the European options market for emissions. → Design implications for the development of emissions trading schemes in other countries. → Governance issues pertaining to emissions trading.

    We examine how state-level factors affect greenhouse gas (GHG) reduction policy preference across the United States by analyzing climate action plans (CAPs) developed in 11 states and surveying the CAP advisory group members. This research offers insights into how states approach the problem of choosing emissions-abatement options that maximize benefits and minimize costs, given their unique circumstances and the constellation of interest groups with power to influence state policy. The state CAPs recommended ten popular GHG reduction strategies to accomplish approximately 90% of emissions reductions, but they recommended these popular strategies in different proportions: a strategy that is heavily relied on in one state's overall portfolio may play a negligible role in another state. This suggests that any national policy to limit GHG emissions should encompass these key strategies, but with flexibility to allow states to balance their implementation for the state's unique geographic, economic, and political circumstances. Survey results strongly support the conclusion that decisions regarding GHG reductions are influenced by the mix of actors at the table. Risk perception is associated with job type for all strategies, and physical and/or geographic factors may underlie the varying reliance on certain GHG reduction strategies across states. - Highlights: > This study analyzed climate action plans from 12 states and surveyed the advisory group members. > Ten strategies supply 90% of recommended emission reductions, but states weigh them differently. > Advisory group members perceived different opportunities and risks in the top-ten strategies. > Both geographic and socio-political factors may underlie the varying reliance on certain strategies. > Cost, business practices and consumer behavior were ranked as the top barriers to reducing emissions.

  5. The program of reclaim negotiable emission licensing: situation and lessons

    Soleille, S.

    2004-01-01

    RECLAIM is an innovative and ambitious program of emission trading that concerns the nitrogen oxides emitted by stationary sources in the Basin of Los Angeles ( United States). It began in 1994 and suffered from various weaknesses. Faced with the Californian energy crisis during the summer of 2000, it could not overcome it. Some power plants have been ejected from the market and are now regulated by a traditional command-and-control approach. The analysis of the RECLAIM program and a comparison with similar markets enable us to point out the weaknesses that led to RECLAIM partial failure and to give some insight into the future evolution of the other emission trading markets.

  6. Multi-model comparison of CO2 emissions peaking in China: Lessons from CEMF01 study

    Oleg Lugovoy

    2018-03-01

    Full Text Available The paper summarizes results of the China Energy Modeling Forum's (CEMF first study. Carbon emissions peaking scenarios, consistent with China's Paris commitment, have been simulated with seven national and industry-level energy models and compared. The CO2 emission trends in the considered scenarios peak from 2015 to 2030 at the level of 9–11 Gt. Sector-level analysis suggests that total emissions pathways before 2030 will be determined mainly by dynamics of emissions in the electric power industry and transportation sector. Both sectors will experience significant increase in demand, but have low-carbon alternative options for development. Based on a side-by-side comparison of modeling input and results, conclusions have been drawn regarding the sources of emissions projections differences, which include data, views on economic perspectives, or models' structure and theoretical framework. Some suggestions have been made regarding energy models' development priorities for further research.

  7. Multi-lateral emission trading: lessons from inter-state NOx control in the United States

    Farrell, A.

    2001-01-01

    Marketable emission permit mechanisms are increasingly proposed as efficient means of managing environmental pollution problems such as greenhouse gas emissions. Existing examples of emissions trading in the literature have so far been limited to domestic efforts put in place through the action of a national legislature, which has no parallel in international politics. This paper examines two efforts to establish multi-lateral emissions trading for nitrogen oxides among various states with the US. One, the Ozone Transport Commission's NO x Budget program is a success. The other, the Ozone Transport Assessment Group and the federal government's subsequent NO x SIP Call has not resulted in a multi-lateral emissions control program, let alone an efficient, market-based one. Due to the relative similarities of the states (compared to highly heterogeneous nations of the world) these are ''best case'' examples, and explaining the vast differences in outcomes will help explain the potential and the challenges in developing an international emission trading program to control greenhouse gas emissions.

  8. The choice of emission trading to combat global warming. Lessons from an economic analysis

    Helioui, K.

    2004-06-01

    The Kyoto Protocol adopted Emission Trading (ET) to control world's greenhouse house gas emissions. However, the viability of this system is under question. This thesis assesses it potential sources of efficiency losses: transaction costs, market power, and dynamic distortions. We show that the last phenomenon is the most worrying. To what extent a control on domestic policies might reduce these distortions? The idea proves impracticable: too many uncertainties surround the relevant control parameters. Comparing quantity against price instruments, we propose a hybrid scheme, ET combined with an international carbon tax, as a compromise between economic efficiency and political acceptability. While ET remains relevant to initiate and enlarge a climate coalition, the introduction of an international carbon tax could, in a second stage, strengthen coordination performances: since it diminishes permit value, it would reduce dynamic distortions and facilitate an agreement on the allocation of future emission rights. Such a hybrid instrument may ensure the long term viability of ET and contribute to the revival of a renewed climate action. (author)

  9. Addressing the CO2 emissions of the world's largest coal producer and consumer: Lessons from the Haishiwan Coalfield, China

    China is now the world's largest user of coal, and also has the highest greenhouse gas emissions associated with the mining and use of coal. In the mining sector, the interests of workforce safety coincide with those of GHG (greenhouse gas) management. While the traditional approach to ensuring workforce safety in coal mines was simply to vent the hazardous gases to the atmosphere, thus increasing GHG emissions, recent innovations have seen elements of CCS (carbon capture and storage) being used to simultaneously ensure workforce safety and minimization of GHG emissions. The Haishiwan Coalfield represents a particularly challenging environment for applying this approach, as the coal-bearing strata host both oil shales and a naturally-occurring CO 2 reservoir, disturbance of which could both imperil workers and lead to elevated GHG emissions. A low-carbon, CCS-based model of gas management developed in the Haishiwan Coalfield offers attractive lessons for application to other coal mines, within and beyond China. This approach achieves multiple benefits: energy production, enhanced workforce safety and minimization of GHG emissions. Given the extreme nature of the Haishiwan case, it ought to be even easier to implement these approaches elsewhere. - Highlights: • Boreholes coalbed CO 2 capture involving oil shales pyrolysis and retorting gas power generation. • A gas hydrate separation and CO 2 injection into abandoned mine for CO 2 capture and storage. • A low-carbon, CCS-based model of gas management developed in the Haishiwan Coalfield

  10. Monte Carlo calculations of neutron and gamm-ray energy spectra for fusion-reactor shield design: comparison with experiment

    Santoro, R.T.; Barnes, J.M.

    1983-08-01

    Neutron and gamma-ray spectra resulting from the interactions of approx. 14-MeV neutrons in laminated slabs of stainless steel type-304 and borated polyethylene have been calculated using the Monte Carlo code MCNP. The calculated spectra are compared with measured data as a function of slab thickness and material composition and as a function of detector location behind the slabs. Comparisons of the differential energy spectra are made for neutrons with energies above 850 keV and for gamma rays with energies above 750 keV. The measured neutron spectra and those calculated using Monte Carlo methods agree within 5% to 50% depending on the slab thickness and composition and neutron energy. The agreement between the measured and calculated gamma-ray energy spectra is also within this range. The MCNP data are also in favorable agreement with attenuated data calculated previously by discrete ordinates transport methods and the Monte Carlo code SAM-CE

    Low emission development strategies (LEDS) articulate economy-wide policies and implementation plans designed to enable a country to meet its long-term development objectives while reducing greenhouse gas emissions. A development impact assessment tool was developed to inform an analytically robust and transparent prioritization of LEDS actions based on their economic, social, and environmental impacts. The graphical tool helps policymakers communicate the development impacts of LEDS options and identify actions that help meet both emissions reduction and development goals. This paper summarizes the adaptation and piloting of the tool in Kenya and Montenegro. The paper highlights strengths of the tool and discusses key needs for improving it.

  12. Nutrient losses and greenhouse gas emissions from dairy production in China: Lessons learned from historical changes and regional differences.

    The dairy industry in China was rapidly expanded and intensified from 1980 to 2010, engendering potential long-term impacts on the environment and natural resources. However, impacts of dairy intensification on nitrogen (N) and phosphorus (P) losses and greenhouse gas (GHG) emissions were unknown. This study was undertaken to examine these relations using the NUtrient flows in Food chains, Environment and Resources use (NUFER)-dairy model. Results showed that milk yield increased by 64% from 1980 to 2010 on average, and the use of concentrate feeds increased by 57% associated with a shift of production from traditional and grassland systems to collective and industrialized systems. At herd level, the N use efficiency (NUE; conversion of N inputs to products) doubled from 7 to 15%, and the P use efficiency (PUE) increased from 10 to 17%, primarily resulting from increased milk yield per cow. In contrast, at the system level, NUE showed a small increase (from 10 to 15%, associated with reduced gaseous losses) while PUE decreased from 46 to 30% due to a large increase in manure discharges. This is attributed to decoupling of feed and dairy production, as the proportion of manure N and P recycled to cropland decreased by 52% and 54%, respectively. Despite this, the average total N loss decreased from 63 to 48gkg -1 milk, and the average GHG emissions from 1.7 to 1.1kgCO 2 equivalentkg -1 milk associated with increased per-cow productivity. However, average P loss increased from 1.4 to 2.8gPkg -1 milk due to higher discharge rate to wastewater and landfill in collective and industrialized systems. Anyhow, average N and P losses exceeded levels in developed countries. There were large regional variations in nutrient use efficiency, nutrient losses and GHG emissions in China, largely determined by the dairy production structure. Average N losses and GHG emissions per unit of milk showed a negative correlation with production intensification based on the proportion of

  13. Extent and agenda of emission reduction policies in front of climate risks: lessons learned from integrated models

    Ambrosi, Ph.

    2004-05-01

    After having highlighted the main difficulties met when trying to take decisions on emission reductions (i.e. disequilibrium between short term action and long term dynamics, series of uncertainties, lack of a clear information on threats), this research aims at studying the extent and the agenda of CO 2 emission reduction efforts at a global scale. First, the author explores under various perspectives the relationship between the extent of climate change and the extent of its impacts and modes of analysis of climate policies. Then, he examines how different attitudes towards the climate risk are translated into recommendations for action which are obtained by always more complex models. In order to compare results, simulations are performed, based on optimal control models belonging to the RESPONSE family. Three different options or attitudes are then studied and assessed with RESPONSE: firstly, the uncertainty on impact and damage assessment is still too important to have confidence in present assessments; secondly, while being sceptical on damage assessment, more confidence is given to climate model results, and thirdly, an explicit representation of climate damages is used to introduce rationality issues in the debate on risks

  14. Lesson of the month 1: Large vessel vasculitis - a diagnostic challenge and the role of 18-fluorodeoxyglucose positron emission tomography.

    Allard, Andrew; Mootoo, Ramesh

    2017-07-01

    Large vessel vasculitis can pose a significant diagnostic challenge. It may be insidious in onset with the only presenting symptoms consisting of constitutional compromise. It may mimic other pathologies and the only serological abnormalities may be abnormal inflammatory markers. Conventional imaging modalities may not be diagnostic. We present a case of large vessel vasculitis that proved a significant diagnostic challenge with diagnosis established on 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) computerised tomography (CT) imaging. This is one of five cases of large vessel vasculitis that were diagnosed in the rheumatology department at our trust over a 12-month period with diagnosis established with the use of 18F-FDG PET CT. We discuss the advantages of 18F-FDG PET CT over more conventional imaging modalities in diagnosing large vessel vasculitis. © Royal College of Physicians 2017. All rights reserved.

  15. Building local institutions for national conservation programs: lessons for developing Reducing Emissions from Deforestation and Forest Degradation (REDD+ programs

    Wain Collen

    2016-06-01

    Full Text Available For programs that aim to promote forest conservation and poverty alleviation, such as Reducing Emissions from Deforestation and Forest Degradation (REDD+, the participation of indigenous communities is essential to meet program goals. Using Ostrom's theory of collective action for common pool resource management, we evaluated the institutions governing indigenous participation in the Programa Socio Bosque incentive-based conservation program in Ecuador. We conducted structured interviews with 94 members in 4 communities to assess community institutions for 6 of Ostrom's principles, using 12 measures we developed for the principles. We found substantial variation between communities in terms of their institutional performance. The best-performing community performed well (>50% of interviewees reported successfully meeting the measure on 8 of the 12 measures. The weakest performed well on only 2 out of 12 measures. Overall, our results indicate that there is stronger performance for constitutional-level institutions, which determine who gets to make the rules, and some collective-choice institutions, which determine how local rules are made. We identified specific challenges with the day-to-day operational institutions that arise from participation in nation state-community conservation programs, such as restricted resource appropriation, monitoring and compliance, and conflict resolution. We found that top-down policy making has an important role to play in supporting communities to establish constitutional-level and some collective-choice institutions. However, developing operational institutions may take more time and depend on local families' day-to-day use of resources, and thus may require a more nuanced policy approach. As some countries and donors find a jurisdictional REDD+ approach increasingly attractive, complementing top-down policy measures with bottom-up institutional development could provide a stronger platform to achieve the

  16. The impacts of emission trends of POPs on human concentration dynamics: Lessons learned from a longitudinal study in Norway (1979-2007).

    Nøst, Therese Haugdahl; Sandanger, Torkjel Manning; Nieboer, Evert; Odland, Jon Øyvind; Breivik, Knut

    2017-06-01

    In this short communication, our focus is on the relationship between human concentrations of select persistent organic pollutants (POPs) and environmental emissions. It is based on a longitudinal study (1979-2007) conducted in Norway. Our aim was to extract general insights from observed and predicted temporal trends in human concentrations of 49 POPs to assist in the design and interpretation of future monitoring studies. Despite considerable decline for polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) since 1986, the sum of the targeted POPs increased from 1979 until 2001, with per- and polyfluorinated alkyl substances (PFASs) dominating recent blood burden measurements. Specifically, the time trends in serum concentrations of POPs, exemplified by PCB-153, 1,1'-(2,2,2-Trichloroethane-1,1-diyl)bis(4-chlorobenzene) (DDT) and perfluorooctane sulfonic acid (PFOS), resembled the trends in available data on their emissions, production or use. These observations suggest that interpretations of human biomonitoring data on persistent compounds must consider historic emissions, which likely vary spatially across the globe. Based on the different temporal trends observed across POP groups, it is evident that generalizations regarding temporal aspects have limitations. The discussion herein underscores the importance of understanding temporal variations in environmental emissions when designing and interpreting human biomonitoring studies.

  18. Lessons Learned

    Amanda Phelan BNS, MSc, PhD

    2015-03-01

    Full Text Available The public health nurses’ scope of practice explicitly includes child protection within their role, which places them in a prime position to identify child protection concerns. This role compliments that of other professions and voluntary agenices who work with children. Public health nurses are in a privileged position as they form a relationship with the child’s parent(s/guardian(s and are able to see the child in its own environment, which many professionals cannot. Child protection in Ireland, while influenced by other countries, has progressed through a distinct pathway that streamlined protocols and procedures. However, despite the above serious failures have occurred in the Irish system, and inquiries over the past 20 years persistently present similar contributing factors, namely, the lack of standardized and comprehensive service responses. Moreover, poor practice is compounded by the lack of recognition of the various interactional processes taking place within and between the different agencies of child protection, leading to psychological barriers in communication. This article will explore the lessons learned for public health nurses practice in safeguarding children in the Republic of Ireland.

  9. Phagocytosis: history's lessons.

    Garg, Manish; Chandawarkar, Rajiv Y

    2013-01-01

    The assimilation of lessons from the past is an essential component of education for scientists of tomorrow. These lessons are not easy to find. History books on science are few and usually highly dramatized and biographies of scientists tend to exaggerate the pomp of scientific discovery. Both underplay the hard and laborious work that is integral to any scientific pursuit. Here we illustrate one such example. A century ago, the Nobel Prize in Medicine was awarded to two scientists: Ilya Metchnikoff, a Russian zoologist, for the discovery ofphagocytosis-a cell-mediated ingestion ofmicrobes; and Paul Ehrlich, a distinguished physician-scientist, for discovering a highly antigen-specific serum-derived antibody-based immune defense. These two diametrically opposing views of the host-pathogen interaction set the stage for a strife that led to seminal advancements in immunology. Mirrored in this journey are important lessons for scientists today--ubiquitously as applicable to modern scientific life as they were a century ago. This commentaryhighlights these lessons--a fitting centenary to a well-deserved recognition.

  2. Lessons on collisionless reconnection from quantum fluids

    Yasuhito eNarita

    2014-12-01

    Full Text Available Magnetic reconnection in space plasmas remains a challenge in physics in that the phenomenon is associated with the breakdown of frozen-in magnetic field in a collisionless medium. Such a topology change can also be found in superfluidity, known as the quantum vortex reconnection. We give a plasma physicists' view of superfluidity to obtain insights on essential processes in collisionless reconnection, including discussion of the kinetic and fluid pictures, wave dynamics, and time reversal asymmetry. The most important lesson from the quantum fluid is the scenario that reconnection is controlled by the physics of topological defects on the microscopic scale, and by the physics of turbulence on the macroscopic scale. Quantum vortex reconnection is accompanied by wave emission in the form of Kelvin waves and sound waves, which imprints the time reversal asymmetry.

    Full Text Available Abstract: Hypnoteaching in History Lesson. Historical learning is a science that can’t be separated in educating the younger generation. Through this lesson, teachers in secondary schools can provide the foundation of nationality through important events in the study of the social sciences. Many of the problems that occur in learning history, such as the boring and make sleepy. Everyone must have heard the term hypnosis, hypnotism, or hypnotherapy. Each person must also have a different view or understanding when hearing these terms. Hypnoteaching is one of the learning methods by using the art of communicating to influence learners. Hypnoteaching is a combination of five teaching-learning methods such as quantum learning, accelerate learning, power teaching, neuro-linguistic programming (NLP and hypnosis. Hypnoteaching can be done using informal hypnosis as well as formal hypnosis. Informal hypnosis is also called indirect hypnosis ie teachers can naturally make the Critical Area learners become no longer critical, through a very persuasive communication pattern. Here's what the teacher can do in Informal hypnosis: (1 get attention; (2 establishing Themes; (3 presenting the structure and regulations; (4 building relationships. If the learners are already comfortable and interested, the next step is to do a formal hypnosis before the lesson begins. Here are the steps that must be done: (1 Induction; (2 Deepening; (3 Deep level test; (4 Suggestion, and; (5 Termination.   Keywords: Historical learning, hypnoteaching, hypnosis, hypnotism, hypnotherapy, history Abstrak: Hipnoteaching dalam Pembelajaran Sejarah.

  7. Lessons of nuclear power

    Collingridge, D.

    1984-01-01

    In an earlier article the author has argued that the turbulent history of nuclear power in Britain and the USA stems from the technology itself, and has little to do with the very different institutional arrangements made for the new technology in the two countries. Nuclear plant has various features which make its planning extraordinarily difficult. Its long lead time, large unit size, capital intensity and dependence on complex infrastructure combine to ensure that mistakes are likely to be made in planning the technology and that what mistakes do occur are expensive. This article aims to expand on the earlier one in two ways; by looking at the apparent success of the French nuclear programme which seems to run counter to the thesis of the earlier article, and by trying to draw lessons from the earlier analysis for the breeder reactor.

  8. Lesson "Balance in Nature

    Chapanova, V.

    2012-04-01

    Lesson "Balance in Nature" This simulation game-lesson (Balance in Nature) gives an opportunity for the students to show creativity, work independently, and to create models and ideas. It creates future-oriented thought connected to their experience, allowing them to propose solutions for global problems and personal responsibility for their activities. The class is divided in two teams. Each team chooses questions. 1. Question: Pollution in the environment. 2. Question: Care for nature and climate. The teams work on the chosen tasks. They make drafts, notes and formulate their solutions on small pieces of paper, explaining the impact on nature and society. They express their points of view using many different opinions. This generates alternative thoughts and results in creative solutions. With the new knowledge and positive behaviour defined, everybody realizes that they can do something positive towards nature and climate problems and the importance of individuals for solving global problems is evident. Our main goal is to recover the ecological balance, and everybody explains his or her own well-grounded opinions. In this work process the students obtain knowledge, skills and more responsible behaviour. This process, based on his or her own experience, dialogue and teamwork, helps the participant's self-development. Making the model "human↔ nature" expresses how human activities impact the natural Earth and how these impacts in turn affect society. Taking personal responsibility, we can reduce global warming and help the Earth. By helping nature we help ourselves. Teacher: Veselina Boycheva-Chapanova " Saint Patriarch Evtimii" Scholl Str.

  9. Lessons learned in radiology

    Goodenough, D.J.

    2001-01-01

    The paper reviews aspects of the history of radiology with the goal of identifying lessons learned, particularly in the area of radiological protection of the patient in diagnostic and interventional radiology, nuclear medicine and radiotherapy. It is pointed out that since the days of Roentgen there has been a need not only to control and quantify the amount of radiation reaching the patient but also to optimize the imaging process to offer the greatest diagnostic benefit within allowable levels of patient dose. To this end, in diagnostic radiology, one finds the development of better films, X rays tubes, grids, screens and processing techniques, while in fluoroscopy, one sees the increased luminance of calcium tungstate. In interventional radiology, one finds an improvement in catheterization techniques and contrast agents. In nuclear medicine, the development of tracer techniques into modern cameras and isotopes such as technetium can be followed. In radiotherapy, one sees the early superficial X rays and radium sources gradually replaced with radon seeds, supervoltage, 60 Co and today's linear accelerators. Along with the incredible advances in imaging and therapeutic technologies comes the growing realization of the potential danger of radiation and the need to protect the patient (as well as physicians, ancillary personnel and the general population) from unnecessary radiation. The important lesson learned is that we must walk a tightrope, balancing the benefits and risks of any technology utilizing radiation to produce the greatest benefits at the lowest acceptable risk. The alternative techniques using non-ionizing radiation will have to be considered as part of the general armamentarium for medical imaging whenever radiation consequences are unacceptable. (author)

  10. Lessons Learned from FUSRAP

    Castillo, Darina [U.S. Department of Energy, Office of Legacy Management; Carpenter, Cliff [U.S. Department of Energy, Office of Legacy Management; Miller, Michele [Navarro Research and Engineering

    2016-03-06

    The US DOE Office of Legacy Management (LM) is the long-term steward for 90 sites remediated under numerous regulatory regimes including the Formerly Utilized Sites Remedial Action Program (FUSRAP) sites. In addition, LM holds considerable historical information, gathered in the 1970s, to determine site eligibility for remediation under FUSRAP. To date, 29 FUSRAP sites are in LM’s inventory of sites for long-term surveillance and maintenance (LTS&M), and 25 are with the US Army Corps of Engineers (USACE) for remediation or in the process of being transitioned to LM. It is forecasted that 13 FUSRAP sites will transfer from the USACE to LM over the next 10 years; however, the timing of the transfers is strongly dependent upon federal funding of the ongoing remedial actions. Historically, FUSRAP sites were generally cleaned up for “unrestricted” industrial use or remediated to the “cleanup standards” at that time, and their use remained unchanged. Today, these sites as well as the adjacent properties are now changing or envisioned to have changes in land use, typically from industrial to commercial or residential uses. The implication of land-use change affects DOE’s LTS&M responsibility for the sites under LM stewardship as well as the planning for the additional sites scheduled to transition in time. Coinciding with land-use changes at or near FUSRAP sites is an increased community awareness of these sites. As property development increases near FUSRAP sites, the general public and interested stakeholders regularly inquire about the sufficiency of cleanups that impact their neighborhoods and communities. LM has used this experience to address a series of lessons learned to improve our program management in light of the changing conditions of our sites. We describe these lessons learned as (1) improved stakeholder relations, (2) enhanced LTS&M requirements for the sites, and (3) greater involvement in the transition process.

  18. Lessons from independence

    Hauptfuhrer, R.R.

    1990-01-01

    The recent history of Oryx provides invaluable lessons for those who plan future energy strategies, relates the author of this paper. When Oryx became an independent oil and gas company, its reserves were declining, its stock was selling below asset values, and the price of oil seemed stuck below $15 per barrel. The message from Oryx management to Oryx employees was: We are in charge of our own destiny. We are about to create our own future. Oryx had developed a new, positive corporate culture and the corporate credit required for growth. This paper points to two basic principles that have guided the metamorphosis in Oryx's performance. The first objective was to improve operational efficiency and to identify the right performance indicators to measure this improvement. It states that the most critical performance indicator for an exploration and production company must be replacement and expansion of reserves at a competitive replacement cost. Oryx has cut its finding costs from $12 to $5 per barrel, while the BP acquisition provided proven reserves at a cost of only $4 per barrel. Another performance indicator measures Oryx's standing in the financial markets

  19. Patient safety: lessons learned

    Bagian, James P.

    2006-01-01

    The traditional approach to patient safety in health care has ranged from reticence to outward denial of serious flaws. This undermines the otherwise remarkable advances in technology and information that have characterized the specialty of medical practice. In addition, lessons learned in industries outside health care, such as in aviation, provide opportunities for improvements that successfully reduce mishaps and errors while maintaining a standard of excellence. This is precisely the call in medicine prompted by the 1999 Institute of Medicine report ''To Err Is Human: Building a Safer Health System.'' However, to effect these changes, key components of a successful safety system must include: (1) communication, (2) a shift from a posture of reliance on human infallibility (hence ''shame and blame'') to checklists that recognize the contribution of the system and account for human limitations, and (3) a cultivation of non-punitive open and/or de-identified/anonymous reporting of safety concerns, including close calls, in addition to adverse events.

    Rhatigan, Jennifer; Neubek, Deborah J.; Thomas, L. Dale

    2011-01-01

    These lessons learned are part of a suite of hardware, software, test results, designs, knowledge base, and documentation that comprises the legacy of the Constellation Program. The context, summary information, and lessons learned are presented in a factual format, as known and described at the time. While our opinions might be discernable in the context, we have avoided all but factually sustainable statements. Statements should not be viewed as being either positive or negative; their value lies in what we did and what we learned that is worthy of passing on. The lessons include both "dos" and "don ts." In many cases, one person s "do" can be viewed as another person s "don t"; therefore, we have attempted to capture both perspectives when applicable and useful. While Volume I summarizes the views of those who managed the program, this Volume II encompasses the views at the working level, describing how the program challenges manifested in day-to-day activities. Here we see themes that were perhaps hinted at, but not completely addressed, in Volume I: unintended consequences of policies that worked well at higher levels but lacked proper implementation at the working level; long-term effects of the "generation gap" in human space flight development, the need to demonstrate early successes at the expense of thorough planning, and the consequences of problems and challenges not yet addressed because other problems and challenges were more immediate or manifest. Not all lessons learned have the benefit of being operationally vetted, since the program was cancelled shortly after Preliminary Design Review. We avoid making statements about operational consequences (with the exception of testing and test flights that did occur), but we do attempt to provide insight into how operational thinking influenced design and testing. The lessons have been formatted with a description, along with supporting information, a succinct statement of the lesson learned, and

  2. Lessons of nuclear robot history

    Oomichi, Takeo

    2014-01-01

    Severe accidents occurred at Fukushima Daiichi Nuclear Power Station stirred up people's great expectation of nuclear robot's deployment. However unexpected nuclear disaster, especially rupture of reactor building caused by core meltdown and hydrogen explosion, made it quite difficult to introduce nuclear robot under high radiation environment to cease accidents and dispose damaged reactor. Robotics Society of Japan (RSJ) set up committee to look back upon lessons learned from 50 year's past experience of nuclear robot development and summarized 'Lessons of nuclear robot history', which was shown on the home page website of RSJ. This article outlined it with personal comment. History of nuclear robot developed for inspection and maintenance at normal operation and for specific required response at nuclear accidents was reviewed with many examples at home and abroad for TMI, Chernobyl and JCO accidents. Present state of Fukushima accident response robot's introduction and development was also described with some comments on nuclear robot development from academia based on lessons. (T. Tanaka)

  3. Overview of lessons learnt

    Pescatore, C.; Federline, M.; Duncan, A.

    2004-01-01

    During the Tarragona International Seminar the participating high-level specialists had very open and fruitful discussion concerning strategic decommissioning issues. The lessons learnt and possible solutions for future work issues can be found below. Although there appears to be a trend towards early dismantling, there seemed to be general agreement that technical solutions support a wide variety of safe decommissioning approaches. Thus, in terms of decommissioning strategy, it appears that no one size fits all. A flexible regulatory approach is needed in order to recognize the changing operational risks and physical conditions of facilities with time, and to optimise their dismantling. The NEA has released a comprehensive study on decommissioning strategies and costs that indicates world-wide progress. According to this report, over 50% of countries with nuclear facilities have a framework of decommissioning requirements and 60% have defined radioactive waste clearance levels. Up to about 70% of the costs of D and D are attributable to dismantling and waste management. The provisions for safety of the D and D process are closely linked to the availability of the necessary funds as and when required. A number of common factors were defined for successful implementation of decommissioning strategies: i.e. safety, technical feasibility of decommissioning options, risk-informed progression of D and D activities as project proceeds, maintenance of competency and corporate memory throughout project, waste management and disposal capability, financing that suits the scope of the project, a well-defined risk-informed and performance-based regulatory process, and establishment of effective communication with local and regional governments and key stakeholders, particularly personnel, at the earliest opportunity before decommissioning.

  5. Lessons learned related to packaging and transportation

    Wallen, C.

    1995-01-01

    The use of lessons learned as a tool for learning from past experiences is well established, especially by many organizations within the nuclear industry. Every person has, at some time, used the principles of lessons learned to adopt good work practices based on their own experiences or the experiences of others. Lessons learned can also help to avoid the recurrence of adverse practices, which is often an area that most lessons-learned programs tend to focus on. This paper will discuss how lessons learned relate to packaging and transportation issues and events experienced at Department of Energy (DOE) facilities. It will also discuss the role performed by the Office of Nuclear and Facility Safety's Office of Operating Experience Analysis and Feedback in disseminating lessons learned and operating experience feedback to the DOE complex. The central concept of lessons learned is that any organization should be able to learn from its own experiences and events. In addition, organizations should implement methodologies to scan external environments for lessons learned, to analyze and determine the relevance of lessons learned, and to bring about the necessary changes learned from these experiences. With increased concerns toward facility safety, the importance of utilizing the lessons-learned principles and the establishment of lessons-learned programs can not be overstated

  6. Governance of CO2 markets: Lessons from the EU ETS

    Perthuis, Christian de; Trotignon, Raphael

    2014-01-01

    The European emissions trading scheme (EU ETS) is the centerpiece of Europe's climate policy. The system has been undermined variously by the weakness of its regulation, an undesirable overlap with other public policies and the far-reaching economic and financial crisis that caused the market price of allowances to plunge. This article attempts to identify the conditions for making the coming years of the EU ETS a success. It draws historical lessons from the eight years the scheme has been in operation, and then presents the various interventions by the public authorities currently under discussion in order to revive the market. Finally, the article proposes to draw lessons from monetary policy by outlining what might be the mandate of an Independent Carbon Market Authority, with responsibility for the dynamic management of the supply of allowances, and whose main mission would be to ensure the optimal linkage between the different temporal horizons of the climate strategy. This article could provide important lessons for schemes developing in the rest of the world, especially in South Korea or in China. - Highlights: • History suggest that ex ante expectations tend to overestimate the constraint. • Economic conditions, policy overlaps, and Kyoto credits cause the current weakness. • “Set aside” or “backloading” does not resolve structural issues. • Changing/extending the reduction target is necessary but not sufficient. • An independent authority could ensure the credibility of the constraint over time

  3. EMU Lessons Learned Database

    Matthews, Kevin M., Jr.; Crocker, Lori; Cupples, J. Scott

    2011-01-01

    As manned space exploration takes on the task of traveling beyond low Earth orbit, many problems arise that must be solved in order to make the journey possible. One major task is protecting humans from the harsh space environment. The current method of protecting astronauts during Extravehicular Activity (EVA) is through use of the specially designed Extravehicular Mobility Unit (EMU). As more rigorous EVA conditions need to be endured at new destinations, the suit will need to be tailored and improved in order to accommodate the astronaut. The Objective behind the EMU Lessons Learned Database(LLD) is to be able to create a tool which will assist in the development of next-generation EMUs, along with maintenance and improvement of the current EMU, by compiling data from Failure Investigation and Analysis Reports (FIARs) which have information on past suit failures. FIARs use a system of codes that give more information on the aspects of the failure, but if one is unfamiliar with the EMU they will be unable to decipher the information. A goal of the EMU LLD is to not only compile the information, but to present it in a user-friendly, organized, searchable database accessible to all familiarity levels with the EMU; both newcomers and veterans alike. The EMU LLD originally started as an Excel database, which allowed easy navigation and analysis of the data through pivot charts. Creating an entry requires access to the Problem Reporting And Corrective Action database (PRACA), which contains the original FIAR data for all hardware. FIAR data are then transferred to, defined, and formatted in the LLD. Work is being done to create a web-based version of the LLD in order to increase accessibility to all of Johnson Space Center (JSC), which includes converting entries from Excel to the HTML format. FIARs related to the EMU have been completed in the Excel version, and now focus has shifted to expanding FIAR data in the LLD to include EVA tools and support hardware such as

  4. UNLEARNED LESSONS OF CONTEMPORARY HISTORY

    А Н Данилов

    2017-12-01

    Full Text Available The article considers the complex geopolitical situation in the global world at the end of the second decade of the 21st century as determined by the consequences of the collapse of the Soviet Union and by the new world order. The author seeks to answer the questions who will define the current geopolitical situation, whose aims it will reflect, what will become the basis of new geopolitical realities, the basis of moral solidarity of humankind, and the spiritual basis of future civilizations. The new challenges give rise to a desperate struggle for different scenarios for building a happy life. Moreover, it is not clear which ideal of the future world will be widely supported as a development guideline. The recognition as such of the standard of living and development of the strongest ones becomes a real threat to the new civilization for it leads to the loss of national interests of sovereign states, and to the loss of an independent future. Today, there is an active search for new theories and concepts that will adequately explain con-temporary global processes. In this thematic context, the author identifies main lessons not learned by the world political elites. The first lesson: new states are not born in an empty place, their common history is a great advantage ensuring prospects for the further development of interstate cooperation. The second lesson: the widespread falsification of history has a negative impact on national, cultural and social-group identity in transforming societies. The third lesson: after the collapse of the Soviet Union, the post-war balance of power was destroyed together with the system of checks and balances in world politics (a bipolar model of the world. The fourth lesson: under radical social transformations, the moral system of the population devaluates with numerous crisis consequences.

  5. Base line definitions and methodological lessons from Zimbabwe

    Maya, R.S.

    1995-01-01

    The UNEP Greenhouse Gas Abatement Costing Studies carried out under the management of the UNEP Collaborating Centre On Energy and Environment at Risoe National Laboratories in Denmark has placed effort in generating methodological approaches to assessing the cost of abatement activities to reduce CO 2 emissions. These efforts have produced perhaps the most comprehensive set of methodological approaches to defining and assessing the cost of greenhouse gas abatement. Perhaps the most importance aspect of the UNEP study which involved teams of researchers from ten countries is the mix of countries in which the studies were conducted and hence the representation of views and concepts from researchers in these countries particularly those from developing countries namely, Zimbabwe, India, Venezuela, Brazil, Thailand and Senegal. Methodological lessons from Zimbabwe, therefore, would have benefited from the interactions with methodological experiences form the other participating countries. Methodological lessons from the Zimbabwean study can be placed in two categories. One relates to the modelling of tools to analyze economic trends and the various factors studied in order to determine the unit cost of CO 2 abatement. The other is the definition of factors influencing the levels of emissions reducible and those realised under specific economic trends. (au)

  7. The Employed Neurosurgeon: Essential Lessons.

    Benzil, Deborah L; Zusman, Edie E

    2017-04-01

    Neurosurgeons are highly specialized surgeons whose pride is mastery of the complexity of form and function that is the nervous system and then knowing when and how these require surgical intervention. Following years of arduous postgraduate education, neurosurgeons enter the world of practice that is not only daunting in its intricacies of regulations, mandates, and unknown business practices, but also changing at a meteoric pace. Overwhelmingly, graduating residents and fellows are choosing to practice as employed physicians, a trend that is new in its magnitude and also changed because of the rapid evolution of large health systems. Case studies of challenges other employed surgical specialists have faced can provide critical and important education for any neurosurgeon in this arena. As with the lessons of all case studies, the teachings are remarkably universal, but how those lessons apply to an individual's specific situation will require personalized adaptation.

    Full Text Available Including in a novel information about relief, climate, vegetation, fauna and various aspects of socio-economic life can make literature a real source of geographical information. Using realistic literary works in Geography lessons has multiple benefits, which are not limited only to geographical knowledge. In this paper there are some fragments from literature, suggestions of activities about how to integrate the fragments during Geography lessons and the results of these activities. The activities are from fifth to twelfth grade, passing through a first example of water pollution resulting from a Hercules labour, through the lyricism of the aurora borealis description, through the dramatic life of a refugee from Darfur, through the Dobrudgea winter landscape, through the grey urban landscape of Bucharest in the 90s and so on. Students were put into learning situations that stimulated their creativity, developed communication competencies and enriched their general knowledge.

    The purpose of this report is to document lessons learned in the installation of the hydrogen fueling station at the National Park Service Brentwood site in Washington, D.C., to help further the deployment of hydrogen infrastructure required to support hydrogen and other fuel cell technologies. Hydrogen fueling is the most difficult infrastructure component to build and permit. Hydrogen fueling can include augmenting hydrogen fueling capability to existing conventional fuel fueling stations as well as building brand new hydrogen fueling stations. This report was produced as part of the Brentwood Lessons Learned project. The project consisted of transplanting an existing modular hydrogen fueling station from Connecticut to the National Park Service Brentwood site. This relocation required design and construction at the Brentwood site to accommodate the existing station design as well as installation and validation of the updated station. One of the most important lessons learned was that simply moving an existing modular station to an operating site was not necessarily straight-forward - performing the relocation required significant effort and cost. The station has to function at the selected operating site and this functionality requires a power supply, building supports connecting to an existing alarm system, electrical grounding and lighting, providing nitrogen for purging, and providing deionized water if an electrolyzer is part of the station package. Most importantly, the station has to fit into the existing site both spatially and operationally and not disrupt existing operations at the site. All of this coordination and integration requires logistical planning and project management. The idea that a hydrogen fueling station can be simply dropped onto a site and made immediately operational is generally not realistic. Other important lessons learned include that delineating the boundaries of the multiple jurisdictions that have authority over a project for

  20. Physically active academic lessons in elementary children.

    Bartholomew, John B; Jowers, Esbelle M

    2011-06-01

    Although schools are an ideal location to conduct interventions that target children, the emphasis on standardized testing makes it difficult to implement interventions that do not directly support academic instruction. In response, physically active academic lessons have been developed as a strategy to increase physical activity while also addressing core educational goals. Texas I-CAN! is one incarnation of this approach. We will review the on-going research on the impact of these active lessons on: teacher implementation, child step count, child attention control, and academic performance. The collected studies support the impact of physically active academic lessons on each area of interest. If these data can be replicated, it suggests that teachers might find these lessons of benefit to their primary role as educators, which should ease dissemination of these and other physically active lessons in elementary schools.

    The Chernobyl accident led to a drastic increase the incidents of thyroid cancer in children living at territories contaminated with radionuclides. The incidents of hemoblastoses which are etiologically closely related to radiation did not change after the incident. The lessons of the decade that passed since the accident necessitate measures aimed at alleviation of the medical consequences of the accident which are to be implemented for many years. The program of such measures should be based on a strictly scientific evaluation of each factor, that will be conductive to a most adequate state financing of this work [ru

  4. Southwest Airlines: lessons in loyalty.

    D'Aurizio, Patricia

    2008-01-01

    Southwest Airlines continues to garner accolades in the areas of customer service, workforce management, and profitability. Since both the health care and airlines industries deal with a service rather than a product, the customer experience depends on the people who deliver that experience. Employees' commitment or "loyalty" to their customers, their employer, and their work translates into millions of dollars of revenue. What employee wants to work for "the worst employer in town?" Nine loyalty lessons from Southwest can be carried over to the health care setting for the benefit of employees and patients.

  6. Intergenerational Lessons and 'Fabulous Stories'.

    Lewenson, Sandra B; Welch, Cathryne A; Hassmiller, Susan B

    2015-10-01

    While directing the Future of Nursing: Campaign for Action, Susan B. Hassmiller, the Robert Wood Johnson Foundation's senior adviser for nursing, realized the value that nursing history could bring to the campaign. She decided to interview her mother, Jacqueline J. Wouwenberg, a 1947 graduate of the Bellevue Hospital School of Nursing, in order to better understand and contextualize changes that had occurred in the nursing profession during the 20th century. In collaboration with nurse historians Cathryne A. Welch and Sandra B. Lewenson, Hassmiller participated in interviewing her mother and was also interviewed herself. The stories that emerged revealed a great deal: each woman had found that nursing had given them countless opportunities that reflected the time periods in which they lived. Wouwenberg's experiences, transmitted to Hassmiller through words and actions, also served as important lessons for her daughter. This article shares five lessons: be independent and courageous, know that nursing has no bounds, follow your passion, honor diversity, and give back. It also asks readers to reflect on the relevance of nurses' work from one generation to the next..

  7. Lessons Learned for Decommissioning Planning

    Sohn, Wook; Kim, Young-gook; Kim, Hee-keun

    2015-01-01

    The purpose of this paper is to introduce the U.S. nuclear industrial's some key lessons learned especially for decommissioning planning based on which well informed decommissioning planning can be carried out. For a successful decommissioning, it is crucial to carry out a well-organized decommissioning planning before the decommissioning starts. This paper discussed four key factors which should be decided or considered carefully during the decommissioning planning period with introduction of related decommissioning lessons learned of U.S. nuclear industry. Those factors which have been discussed in this paper include the end state of a site, the overall decommissioning strategy, the management of the spent fuels, and the spent fuel pool island. Among them, the end state of a site should be decided first as it directs the whole decommissioning processes. Then, decisions on the overall decommissioning strategy (DECON vs. SAFSTOR) and the management of the spent fuels (wet vs. dry) should follow. Finally, the spent fuel pool island should be given due consideration because its implementation will result in much cost saving. Hopefully, the results of this paper would provide useful inputs to performing the decommissioning planing for the Kori unit 1

  8. Alternative Energy Lessons in Scotland

    Boyle, Julie

    2010-05-01

    In Scotland the new science curriculum for pupils aged 12 to 15 shall include the following outcomes: "Using my knowledge and understanding, I can express an informed view on a national or global environmental issue;" "I have participated in constructing a model to harness a renewable source of energy and can investigate how to optimise the output;" and "I can discuss why it is important to me and to the future of the world that alternatives to fossil fuels are developed." There will be an emphasis on creating lessons that will nurture responsible citizens, improve pupil engagement and allow students to develop their team working skills. To help teachers plan lessons to address this, the Scottish Schools Equipment Research Centre and Edinburgh University made teaching materials on four renewable energy resources. This poster describes how their suggested activities on solar cells, wind turbines, hydroelectric power stations and wave power were used in science lessons with twelve year old students. After an initial class discussion based on issues related to climate change and diminishing fossil fuel supplies, a workshop activity was carried out in three stages. The students were issued with a fact sheet about one of four imaginary islands (Skisdale, Cloudy Island, Surfsville and Sun City) and they were asked to work in teams to choose the most suitable method of generating electricity for their island. Issues such as costs, where it will be sited and environmental implications were considered. They were then asked to conduct practical activities by constructing and testing models for these forms of renewable energy. To conclude, they presented their proposal to the rest of the class with reasoned explanations. The kits used in the lessons can be purchased from Anderson Scientific (sales@andersonscientific.co.uk). The solar cells were simply connected to a voltmeter. The wind and hydroelectric groups used the same basic equipment. This was made using a small water

  9. Experience gained with energy taxes in Europe - Lessons for Switzerland

    Peter, M.; Lueckge, H.; Iten, R.; Trageser, J.; Goerlach, B.; Blobel, D.; Kraemer, A.

    2007-12-01

    This comprehensive final report for the Swiss Federal Office of Energy (SFOE) takes a look at experience gained with energy taxes in Europe and the lessons that can be learned for Switzerland. The variety of energy and CO 2 taxes that have been introduced in Europe since the early 1990s is reviewed. These are intended to reduce energy consumption and CO 2 emissions and complement conventional mineral oil taxes. Some of these non-fiscal energy and CO 2 taxes that have been created within the scope of the EU directive on energy taxation are examined and commented on, as is their impact on energy consumption. The situation in EU member states is described and commented on. Success-factors and general conditions are examined and conclusions that can be drawn for Switzerland are examined.

    Unnerstall, Thomas

    2017-07-01

    The book presents a comprehensive and systematic account of the concept, the current status and the costs of the German energy transition: the Energiewende. Written by an insider who has been working in the German energy industry for over 20 years, it follows a strictly non-political, neutral approach and clearly outlines the most relevant facts and figures. In particular, it describes the main impacts of the Energiewende on the German power system and Germany's national economy. Furthermore, it addresses questions that are of global interest with respect to energy transitions, such as the cost to the national economy, the financial burden on private households and companies and the actual effects on CO{sub 2} emissions. The book also discusses what could have been done better in terms of planning and implementing the Energiewende, and identifies important lessons for other countries that are considering a similar energy transition.

  12. Health communication: lessons from research.

    Shanmugam, A V

    1981-01-01

    In discussing the lessons learned from research in the area of health communication, focus is on basic strategic issues; the scope of health communications in terms of audience, information, education and motivation approaces and India's satellite Instructional Television Experiment (SITE). Health communication is the process by which a health idea is transferred from a source, such as a primary health center, to a receiver, community, with the intention of changing the community's behavior. This involves the formulation of specific strategies for the conduct of health and family welfare communication. In the processs of health communication, it has been a common practice in India as well as in other developing countries to depend upon a plethora of communication media. Yet, despite maximum utilization of the mass media and interpersonal channels of communication, questions remain about the efficacy of the system in bringing about change. Thus, the need to draw upon lessons from research becomes obvious. Communication effectiveness researches have concentrated on 3 basic strategic issues: the question of physical reception of messages by the audience; interpretation or understanding of messages on the part of the audience in accordance with the intention of the communicator; and effectiveness of communication on the cognitive, affective and behavioral dimensions of the audience. Innumberable researches in communication have provided several lessons which have expanded the scope of health communication. This expansion can be observed in terms of audiences reached, information disseminated, education undertaken, and motivation provided. Research has identified several distinct groups to whom specific health messages have to be addressed. These include government and political elites, health and family welfare program administrators, and the medical profession and clinical staff. Information on health needs to include both the concept of health and the pertinent ideas

  18. Lessons from World War I

    John Scales Avery

    2014-05-01

    Full Text Available The history of World War I is reviewed, starting with a discussion of the development of nationalist movements in Europe. It is pointed out that the global disaster started with a seemingly small operation by Austria, which escalated uncontrollably into an all-destroying conflagration. A striking feature of the war was that none of the people who started it had any idea of what it would be like. Technology had changed the character of war, but old patterns of thought remained in place. We also examine the roots of the war in industrial and colonial competition, and in an arms race. Finally, parallels with current events, and the important lessons for today’s world are discussed.

  19. WPPSS debacle: explanations and lessons

    Meyer, M.B.

    1984-01-01

    Principal explanations for the WPPSS events to date can be more or less satisfactorily derived. Five explanations appear to dominate: (1) the long and previously successful history of public power in the Pacific Northwest; (2) overoptimism by architect/engineers and consulting engineers about construction costs and construction durations; (3) laxness by bond counsel in scrutinizing and disclosing potential legal impediments to the various transactions involved; (4) WPPSS easy access to capital markets, combined with naivete in those markets; and (5) the inability of WPPSS to manage and oversee the construction process. This paper explains the specific reasons for, and the importance of, each of these five explanations for the WPPSS debacle. It then develops lessons and conclusions for the future which can be derived from this debacle. 12 references

    This paper presents a study performed by the European Clearinghouse of the Joint Research Centre on Operational Experience for nuclear power plants in cooperation with IRSN and GRS covering events reported by nuclear power plants in relation to external hazards. It summarizes the review of 235 event reports from 3 different databases. The events were grouped in 9 categories according to the nature of the external hazard involved, and the specific lessons learned and recommendations that can be derived from each of these categories are presented. Additional 'cross-cutting' recommendations covering several or all the external hazards considered are also discussed. These recommendations can be useful in preventing this type of events from happening again or in limiting their consequences. The study was launched in 2010 and therefore it does not cover the Fukushima event. This paper presents the main findings and recommendations raised by this study. (orig.)

  1. Lessons learned: wrong intraocular lens.

    2012-10-01

    To report cases involving the placement of the wrong intraocular lens (IOL) at the time of cataract surgery where human error occurred. Retrospective small case series, convenience sample. Seven surgical cases. Institutional review of errors committed and subsequent improvements to clinical protocols. Lessons learned and changes in procedures adapted. The pathways to a wrong IOL are many but largely reflect some combination of poor surgical team communication, transcription error, lack of preoperative clarity in surgical planning or failure to match the patient, and IOL calculation sheet with 2 unique identifiers. Safety in surgery involving IOLs is enhanced both by strict procedures, such as an IOL-specific "time-out," and the fostering of a surgical team culture in which all members are encouraged to voice questions and concerns.

  2. Emergency preparedness lessons from Chernobyl

    Martin, J.B.

    1987-09-01

    Emergency preparedness at nuclear power plants in the US has been considerably enhanced since the Three Mile Island accident. The Chernobyl accident has provided valuable data that can be used to evaluate the merit of some of these enhancements and to determine the need for additional improvements. For example, the USSR intervention levels of 25 rem and 75 rem for evacuation are contrasted with US Environmental Protection Agency protective action guides. The manner in which 135,000 persons were evacuated from the 30-km zone around Chernobyl is constrasted with typical US evacuation plans. Meteorological conditions and particulate deposition patterns were studied to infer characteristics of the radioactive plume from Chernobyl. Typical plume monitoring techniques are examined in light of lessons learned by the Soviets about plume behavior.

  8. Energy efficiency and renewable energies: first lessons learned from AFD and FFEM funding

    Ries, Alain; Dubus, Koulm; Naudet, Jean David

    2008-04-01

    The French Agency for Development (AFD) has been always more involved in projects dealing with issues related to global warming, and more particularly in projects aiming at developing energy efficiency and renewable energies, these projects involved different expertises (energy, urban planning, transports, agriculture, and so on). In order to highlight lessons learned from these diversity of projects and interventions, this report first proposes an analysis of these projects related to energy efficiency and renewable energies in terms of concerned sectors, of intervener, of funding type, and of evolution in time. Then, the authors highlight lessons learned in terms of project starting conditions (national framework, funding, technical abilities, social and environmental factors), in terms of funding conditions for these projects (concessional financing, specialised credit lines), and in terms of climatic impact assessment and of criteria of project selection (practices and reductions of greenhouse gas emissions, improvement of the climatic impact for project financed by the AFD)

  9. Emissions trading for climate policy - US and European perspectives

    Bernd Hansjuergens (ed.) [Martin Luther-Universitaet Halle-Wittenburg (Germany)

    2005-07-01

    The 1997 Kyoto Conference introduced emissions trading as a new policy instrument for climate protection. Bringing together scholars in the fields of economics, political science and law, this book provides a description, analysis and evaluation of different aspects of emissions trading as an instrument to control greenhouse gases. The authors analyse theoretical aspects of regulatory instruments for climate policy, provide an overview of US experience with market-based instruments, draw lessons from existing trading schemes for the control of greenhouse gases, and discuss options for emissions trading in climate policy. They also highlight the background of climate policy and instrument choice in the US and Europe and of the emerging new systems in Europe, particularly the new EU's directive for a CO{sub 2} emissions trading system. 8 figs., 15 tabs.

  10. Analysing the integration of engineering in science lessons with the Engineering-Infused Lesson Rubric

    Peterman, Karen; Daugherty, Jenny L.; Custer, Rodney L.; Ross, Julia M.

    2017-09-01

    Science teachers are being called on to incorporate engineering practices into their classrooms. This study explores whether the Engineering-Infused Lesson Rubric, a new rubric designed to target best practices in engineering education, could be used to evaluate the extent to which engineering is infused into online science lessons. Eighty lessons were selected at random from three online repositories, and coded with the rubric. Overall results documented the strengths of existing lessons, as well as many components that teachers might strengthen. In addition, a subset of characteristics was found to distinguish lessons with the highest level of engineering infusion. Findings are discussed in relation to the potential of the rubric to help teachers use research evidence-informed practice generally, and in relation to the new content demands of the U.S. Next Generation Science Standards, in particular.

    Cox, S.; Benioff, R.

    2011-05-01

    The Coordinated Low Emissions Assistance Network (CLEAN) is a voluntary network of international practitioners supporting low-emission planning in developing countries. The network seeks to improve quality of support through sharing project information, tools, best practices and lessons, and by fostering harmonized assistance. CLEAN has developed an inventory to track and analyze international technical support and tools for low-carbon planning activities in developing countries. This paper presents a preliminary analysis of the inventory to help identify trends in assistance activities and tools available to support developing countries with low-emission planning.

  17. N Reactor Lessons Learned workshop

    Heaberlin, S.W.

    1993-07-01

    This report describes a workshop designed to introduce participants to a process, or model, for adapting LWR Safety Standards and Analysis Methods for use on rector designs significantly different than LWR. The focus of the workshop is on the ''Lessons Learned'' from the multi-year experience in the operation of N Reactor and the efforts to adapt the safety standards developed for commercial light water reactors to a graphite moderated, water cooled, channel type reactor. It must be recognized that the objective of the workshop is to introduce the participants to the operation of a non-LWR in a LWR regulatory world. The total scope of this topic would take weeks to provide a through overview. The objective of this workshop is to provide an introduction and hopefully establish a means to develop a longer term dialogue for technical exchange. This report provides outline of the workshop, a proposed schedule of the workshop, and a description of the tasks will be required to achieve successful completion of the project

  18. Achievements and Lessons from Tevatron

    Shiltsev, V.

    2011-01-01

    For almost a quarter of a century, the Tevatron proton-antiproton collider was the centerpiece of the world's high energy physics program - beginning operation in December of 1985 until it was overtaken by LHC in 2011. The aim of the this unique scientific instrument was to explore the elementary particle physics reactions with center of mass collision energies of up to 1.96 TeV. The initial design luminosity of the Tevatron was 10 30 cm -2 s -1 , however as a result of two decades of upgrades, the accelerator has been able to deliver 430 times higher luminosities to each of two high luminosity experiments, CDF and D0. Tevatron will be shut off September 30, 2011. The collider was arguably one of the most complex research instruments ever to reach the operation stage and is widely recognized for many technological breakthroughs and numerous physics discoveries. Below we briefly present the history of the Tevatron, major advances in accelerator physics, and technology implemented during the long quest for better and better performance. We also discuss some lessons learned from our experience.

  19. FRMAC-93 lessons learned report

    Kerns, K.C.

    1994-03-01

    FRMAC-93 simulated a radiological accident at the Fort Calhoun nuclear power plant, 25 miles north of Omaha, Nebraska. The exercise involved the state Iowa and Nebraska, NRC as the lead Federal agency, FRMAC (Federal Radiological Monitoring and Assessment Center), and several federal agencies with statutory emergency responsibility. FRMAC-93 was a major 2-day field exercise designed to determine the effectiveness, coordination, and operations of a DOE-managed FRMAC. Other objectives were to ensure that appropriate priorities were established and assistance was provided to the states and the lead Federal agency by FRMAC. Day 1 involved the Fort Calhoun evaluated plume phase exercise. On Day 2, the flow of data, which was slow initially, improved so that confidence of states and other federal responders in FRMAC support capabilities was high. The impact and lessons learned from FRMAC-93 provided the necessary impetus to make organizational and operational changes to the FRMAC program, which were put into effect in the DOE exercise FREMONT at Hanford 3 months later

  20. Science and Sandy: Lessons Learned

    Werner, K.

    2013-12-01

    Following Hurricane Sandy's impact on the mid-Atlantic region, President Obama established a Task Force to '...ensure that the Federal Government continues to provide appropriate resources to support affected State, local, and tribal communities to improve the region's resilience, health, and prosperity by building for the future.' The author was detailed from NOAA to the Task Force between January and June 2013. As the Task Force and others began to take stock of the region's needs and develop plans to address them, many diverse approaches emerged from different areas of expertise including: infrastructure, management and construction, housing, public health, and others. Decision making in this environment was complex with many interests and variables to consider and balance. Although often relevant, science and technical expertise was not always at the forefront of this process. This talk describes the author's experience with the Sandy Task Force focusing on organizing scientific expertise to support the work of the Task Force. This includes a description of federal activity supporting Sandy recovery efforts, the role of the Task Force, and lessons learned from developing a science support function within the Task Force.

  7. ELPSA AS A LESSON DESIGN FRAMEWORK

    Tom Lowrie

    2015-07-01

    Full Text Available This paper offers a framework for mathematics lesson design that is consistent with the way we learn about, and discover, most things in life. In addition, the framework provides a structure for identifying how mathematical concepts and understanding are acquired and developed. This framework is called ELPSA and represents five learning components, namely: Experience, Language, Pictorial, Symbolic and Applications. This framework has been used in developing lessons and teacher professional programs in Indonesia since 2012 in cooperation with the World Bank. This paper describes the theory that underlines the framework in general and in relation to each inter-connected component. Two explicit learning sequences for classroom practice are described, associated with Pythagoras theorem and probability. This paper then concludes with recommendations for using ELPSA in various institutional contexts.Keywords: ELPSA, lesson design framework, Pythagoras theorem, probability DOI: dx.doi.org/10.22342/jme.62.77

  8. Applying Lessons from SN Studies to GRBs

    Fryer, Chris L.

    2009-01-01

    Supernovae and Gamma-Ray bursts display many similarities, both in their observational qualities and in the engines behind these powerful explosions. Although not identical, there is a strong synergy in the study of these two objects. There is much the gamma-ray burst field can learn from the lessons of the more-developed supernova field, but the supernova field can also learn from new techniques developed for gamma-ray burst studies. Here I review some of the 'lessons learned' from these fields to help foster this synergy.

  9. Lessons learned from early criticality accidents

    Malenfant, R.E.

    1996-01-01

    Four accidents involving the approach to criticality occurred during the period July, 1945, through May, 1996. These have been described in the format of the OPERATING EXPERIENCE WEEKLY SUMMARY which is distributed by the Office of Nuclear and Facility Safety. Although the lessons learned have been incorporated in standards, codes, and formal procedures during the last fifty years, this is their first presentation in this format. It is particularly appropriate that they be presented in the forum of the Nuclear Criticality Technology Safety Project Workshop closest to the fiftieth anniversary of the last of the four accidents, and that which was most instrumental in demonstrating the need to incorporate lessons learned

  10. Lessons Learned In Developing The VACIS Products

    Orphan, Victor J.

    2011-01-01

    SAIC's development of VACIS provides useful 'lessons learned' in bridging the gap from an idea to a security or contraband detection product. From a gamma densitometer idea for solving a specific Customs Service (CS) requirement (detection of drugs in near-empty tanker trucks) in mid-1990's, SAIC developed a broad line of vehicle and cargo inspections systems (over 500 systems deployed to date) based on a gamma-ray radiographic imaging technique. This paper analyzes the reasons for the successful development of VACIS and attempts to identify ''lessons learned'' useful for future security and contraband detection product developments.

  12. Lessons Learned from ISS Cooperation

    Jolly, C.

    2002-01-01

    Forty years of human spaceflight activities are now culminating in the International Space Station program (ISS). The ISS involves fifteen nations, working together to create a permanently occupied orbital facility that will support scientific and potentially, commercial endeavours. The assembly of the ISS is scheduled to be completed later in this decade, after which it will be operated for at least ten years. At the strategic level, such a complex international project is highly dependent on the fifteen Partners' respective internal politics and foreign policies. On the operational level, Partners still have certain difficulties in issuing and agreeing to common technical procedures. As with almost all aspects of International Space Station cooperation, the Partners are going through a constant learning process, where they have to deal with complex political, legal and operational differences. Intergovernmental Agreement and the Memoranda of Understanding, the instruments forming the legal backbone of the International Space Station cooperation, are still lacking a fair number of arrangements that need to be created for completing and operating the Station. The whole endeavour is also a constant learning process at the operational level, as astronauts, cosmonauts, engineers and technicians on the ground with different cultural and educational backgrounds, learn to work together. One recent Space Shuttle mission to the Station showed the importance of standardising even trivial system components such as packaging labels, as it took the astronauts half a day more than planned to correctly unpack the equipment. This paper will provide a synthesis of some of the main lessons learned during the first few years of International Space Station's lifetime. Important political, legal and operational issues will be addressed and combined. This analysis will provide some guidelines and recommendations for future international space projects, such as an international human

  13. Lessons from Fukushima - February 2012

    Morris-Suzuki, Tessa; Boilley, David; McNeill, David; Gundersen, Arnie; Beranek, Jan; Blomme, Brian; Hanaoka, Wakao; Schulz, Nina; Stensil, Shawn-Patrick; Teule, Rianne; Tumer, Aslihan; McCann, Christine; Otani, Nanako; Hirsch, Helmut

    2012-01-01

    It has been almost 12 months since the Fukushima nuclear disaster began. Although the Great East Japan earthquake and the following tsunami triggered it, the key causes of the nuclear accident lie in the institutional failures of political influence and industry-led regulation. It was a failure of human institutions to acknowledge real reactor risks, a failure to establish and enforce appropriate nuclear safety standards and a failure to ultimately protect the public and the environment. This report, commissioned by Greenpeace International, addresses what lessons can be taken away from this catastrophe. The one-year memorial of the Fukushima accident offers a unique opportunity to ask ourselves what the tragedy - which is far from being over for hundreds of thousands of Japanese people - has taught us. And it also raises the question, are we prepared to learn? There are broader issues and essential questions that still deserve our attention: - How it is possible that - despite all assurances - a major nuclear accident on the scale of the Chernobyl disaster of 1986 happened again, in one of the world's most industrially advanced countries? - Why did emergency and evacuation plans not work to protect people from excessive exposure to the radioactive fallout and resulting contamination? Why is the government still failing to better protect its citizens from radiation one year later? - Why are the over 100,000 people who suffer the most from the impacts of the nuclear accident still not receiving adequate financial and social support to help them rebuild their homes, lives and communities? These are the fundamental questions that we need to ask to be able to learn from the Fukushima nuclear disaster. This report looks into them and draws some important conclusions: 1. The Fukushima nuclear accident marks the end of the 'nuclear safety' paradigm. 2. The Fukushima nuclear accident exposes the deep and systemic failure of the very institutions that are supposed to

  15. Plasma emission mechanisms

    Melrose, D.B.

    1985-01-01

    Only three emission processes are thought to play a role in solar radio emission: plasma emission, gyromagnetic emission and bremsstrahlung. In this chapter plasma emission is discussed and the processes involved in its production are treated, namely, the generation of Langmuir turbulence, the partial conversion into fundamental transverse radiation, production of secondary Langmuir waves and the generation of second-harmonic transverse radiation. (U.K.)

  16. Ion cyclotron emission by spontaneous emission

    Da Costa, O [Commission of the European Communities, Abingdon (United Kingdom). JET Joint Undertaking; Gresillon, D [Ecole Polytechnique, 91 - Palaiseau (France). Lab. de Physique des Milieux Ionises

    1994-07-01

    The goal of the study is to examine whether the spontaneous emission can account for ICE (ion cyclotron emission) experimental results, or part of them. A straightforward approach to plasma emission is chosen, investigating the near equilibrium wave radiation by gyrating ions, and thus building from the majority and fast fusion ions the plasma fluctuations and emission on the fast magnetoacoustic or compressional Alfven wave mode in the IC frequency range. Similarities with the ICE experiments are shown: the emission temperature in the presence of fast ions (even in a very small amount), the strong fast ion emission increase with the harmonic, the fine double-line splitting of each peak, the linear but not proportional increase of the peak width with the harmonic. 3 refs., 2 figs.

  18. GHG legislation: Lessons from Taiwan

    Huang, W.M.; Lee, Grace W.M.

    2009-01-01

    Taiwan has drafted a Greenhouse Gas (GHG) Reduction Bill in 2006, which is currently undergoing the legislative process in the Congress. The purpose of this study is to reexamine the legal framework and contents of this Bill, evaluate potential problems and propose recommendations. This study advocates that setting the GHG reduction targets should be settled in this Bill. In addition, based on the analysis of international experiences, it is recommenced that emissions trading scheme in the Bill should be focused on large emission sources and the share of allowance auction should be increased to reduce gratis allocation. Furthermore, from the calculation results based on the long-range energy alternative planning (LEAP) model, a conflict is observed for the existing energy policy and GHG reduction efforts in Taiwan. That is, coal-burning power plants will be the most important source of energy for Taiwan in the future. In order to reduce this conflict, the authors have recommended that the Bill should also be integrated with other relevant existing legislation to achieve a complementary effect.

  7. Lessons learned on digital systems safety

    Sivertsen, Terje

    2005-06-01

    A decade ago, in 1994, lessons learned from Halden research activities on digital systems safety were summarized in the reports HWR-374 and HWR-375, under the title 'A Lessons Learned Report on Software Dependability'. The reports reviewed all activities made at the Halden Project in this field since 1977. As such, the reports provide a wealth of information on Halden research. At the same time, the lessons learned from the different activities are made more accessible to the reader by being summarized in terms of results, conclusions and recommendations. The present report provides a new lessons learned report, covering the Halden Project research activities in this area from 1994 to medio 2005. As before, the emphasis is on the results, conclusions and recommendations made from these activities, in particular how they can be utilized by different types of organisations, such as licensing authorities, safety assessors, power companies, and software developers. The contents of the report have been edited on the basis of input from a large number of Halden work reports, involving many different authors. Brief summaries of these reports are included in the last part of the report. (Author)

    Janna Linnansaari

    2015-05-01

    Full Text Available The decreasing number of students who are engaged in science learning has been recognised as a problem. The pre-conditions of engagement and actual engagement were examined using a novel research method to obtain detailed information on Finnish students’ engagement in different situations and to gain a better understanding of this phenomenon. The study’s participants consisted of 68 students (31 girls, 37 boys from 9th grade and 67 students (46 girls, 21 boys from 1st grade in upper secondary school. The research aimed to answer the following question: How does Finnish students’ engagement occur in exact and life science lessons? Participants received smartphones equipped with a smartphone application that included an experience sampling method questionnaire. The smartphones were programmed to emit a signal during every science lesson and otherwise randomly during the day (from 8 am to 8 pm. The results reveal that situation and grade had significant effects on students’ pre-conditions of engagement and actual engagement. Our results also show that girls had the highest interest in life science lessons and boys in exact science lessons.

  8. Vehicle Emissions Risk Management

    Ibrahem, L.G.

    2004-01-01

    Vehicle emissions are considered as a main source for air pollution. Emissions regulation is now well developed in most countries to meet cleaner air quality. Reducing emissions by using cleaner fuels, which meet certain specification, is not enough to get cleaner air, yet the vehicle technology is not improved. Here we will outline the following: - development in fuel specification and emissions regulation. main facts linking vehicle emissions, fuel properties and air quality. catalytic converter technology. Emissions sources: In modem cities, vehicle traffic is potentially a major source of emissions. However sometimes other sources of emissions from industry and other stationary sources can be equally important and include emissions that are of greater toxicity than those from vehicles

  9. Lessons learned from failure analysis

    Le May, I.

    2006-01-01

    Failure analysis can be a very useful tool to designers and operators of plant and equipment. It is not simply something that is done for lawyers and insurance companies, but is a tool from which lessons can be learned and by means of which the 'breed' can be improved. In this presentation, several failure investigations that have contributed to understanding will be presented. Specifically, the following cases will be discussed: 1) A fire at a refinery that occurred in a desulphurization unit. 2) The failure of a pipeline before it was even put into operation. 3) Failures in locomotive axles that took place during winter operation. The refinery fire was initially blamed on defective Type 321 seamless stainless steel tubing, but there were conflicting views between 'experts' involved as to the mechanism of failure and the writer was called upon to make an in-depth study. This showed that there were a variety of failure mechanism involved, including high temperature fracture, environmentally-induced cracking and possible manufacturing defects. The unraveling of the failure sequence is described and illustrated. The failure of an oil transmission was discovered when the line was pressure tested some months after it had been installed and before it was put into service. Repairs were made and failure occurred in another place upon the next pressure test being conducted. After several more repairs had been made the line was abandoned and a lawsuit was commenced on the basis that the steel was defective. An investigation disclosed that the material was sensitive to embrittlement and the causes of this were determined. As a result, changes were made in the microstructural control of the product to avoid similar problems in future. A series of axle failures occurred in diesel electric locomotives during winter. An investigation was made to determine the nature of the failures which were not by classical fatigue, nor did they correspond to published illustrations of Cu

  20. Lessons learned in CMAM implementation

    Dent, Nicky; Brown, Rebecca

    2014-01-01

    -going. Despite the need to adapt protocols and approaches to each specific context, there is a need for a common research agenda and sharing of what works and does not. Concerted efforts have been made to improve information-sharing and to draw on lessons learned to advance technical and organisational challenges. However many health workers have limited access to quality information due to barriers such as internet access and language. For example, one recent initiative identified less than 10% of resources are available in French, despite high caseloads of acute malnutrition in francophone West Africa. Key actions to address challenges in information-sharing include: -Improve availability of and access to translated information -Increase use of social media, e-learning and audio-visual materials for extended reach and use of information -Stimulate interactive dialogue and sharing between practitioners for improved problem solving and learning -Strengthen the collaboration between complementary initiatives. In one decade significant advances in the adaptation and implementation of community-based management of acute malnutrition approach have been made in various contexts, but challenges to quality service delivery, scale-up and sustainability remain. It is time to draw on what we know to support scale-up and have equitable access to treatment to the millions of children who still remain outside of existing services. (author)

  1. Blue Emission in Proteins

    Sarkar, Sohini; Sengupta, Abhigyan; Hazra, Partha; Mandal, Pankaj

  4. Sharing Lessons Learned Between Industries in EU

    Muehleisen, A.; Strucic, M.

    2012-01-01

    Recent events in nuclear industry remind us on importance of continuous sharing of the knowledge and experience gained through evaluations of incidents and accidents. We frequently use experience from our daily life activities to improve our performance and avoid some mistakes or unwanted events. In the similar way we can use other industries experience. These experiences can be applied to improve nuclear safety. For example, Safety Culture, which has a great influence on the level of nuclear power plants safety, is similarly presented in other industries. Mechanisms which led to accidents from weak safety culture in one branch of other industry could be comparable to those in nuclear industry. Some other industries have many more cumulative years of experience than nuclear industry. Aviation and Oil industries are typical representatives. Part of their experience can be used in nuclear industry too. Number of reports from nuclear power plants showed us that not only specific equipment related causes lay behind accidents; there are also other causes and contributors which are more common for all industries. Hence lessons learned in other industry should be assessed and used in nuclear industry too. In the European Union, a regional initiative has been set up in 2008 in support of EU Member State nuclear safety authorities, but also EU technical support organizations, international organizations and the broader nuclear community, to enhance nuclear safety through improvement of the use of lessons learned from operational experience of nuclear power plants (NPPs). The initiative, called ''the EU Clearinghouse on Operational Experience Feedback for NPP'', is organized as a network operated by a centralized office located at the Joint Research Centre of the European Commission. The reduction of occurrence and significance of events in NPPs and their safe operation is its ultimate goal. Among others EU Clearinghouse provides services such as technical and scientific

  5. Lessons learned from fatique failures in major FWR components

    Ware, A.G.; Shah, V.N.

    1992-01-01

    This paper evaluates the field fatigue failure experience and describes the lessons learned that can be employed in managing fatigue damage at the sites of these failures and at other susceptible sites. Fatigue damage has resulted in cracks on the inside surfaces of vessels and piping, and in some cases, through-wall cracks resulting in coolant leakage. All of the fatigue failures resulted from conditions or stressors that were not accounted for in the original design analyses. In some cases, it has proven difficult to discover fatigue cracks using conventional inservice inspection methods; several cracks were detected because of leakage. Supplementary monitoring and inspection techniques such as fatigue monitoring, acoustic emission monitoring, and time-of-flight-diffraction ultrasonic testing can be used to assist in identifying susceptible sites, estimating crack growth, and sizing existing fatigue cracks. It is important to identify the root cause of failures because once the stressors and degradation mechanisms are known, changes in operating procedures and designs can be implemented to mitigate future fatigue damage

  6. Sustainable Fashion Supply Chain: Lessons from H&M

    Bin Shen

    2014-09-01

    Full Text Available Sustainability is significantly important for fashion business due to consumers’ increasing awareness of environment. When a fashion company aims to promote sustainability, the main linkage is to develop a sustainable supply chain. This paper contributes to current knowledge of sustainable supply chain in the textile and clothing industry. We first depict the structure of sustainable fashion supply chain including eco-material preparation, sustainable manufacturing, green distribution, green retailing, and ethical consumers based on the extant literature. We study the case of the Swedish fast fashion company, H&M, which has constructed its sustainable supply chain in developing eco-materials, providing safety training, monitoring sustainable manufacturing, reducing carbon emission in distribution, and promoting eco-fashion. Moreover, based on the secondary data and analysis, we learn the lessons of H&M’s sustainable fashion supply chain from the country perspective: (1 the H&M’s sourcing managers may be more likely to select suppliers in the countries with lower degrees of human wellbeing; (2 the H&M’s supply chain manager may set a higher level of inventory in a country with a higher human wellbeing; and (3 the H&M CEO may consider the degrees of human wellbeing and economic wellbeing, instead of environmental wellbeing when launching the online shopping channel in a specific country.

  7. International emissions trading

    Boom, Jan Tjeerd

    This thesis discusses the design and political acceptability of international emissions trading. It is shown that there are several designs options for emissions trading at the national level that have a different impact on output and thereby related factors such as employment and consumer prices....... The differences in impact of the design make that governments may prefer different designs of emissions trading in different situations. The thesis furthermore establishes that international emissions trading may lead to higher overall emissions, which may make it a less attractive instrument....

  8. Shipping emissions in ports

    Merk, Olaf

    2014-01-01

    Shipping emissions in ports are substantial, accounting for 18 million tonnes of CO2 emissions, 0.4 million tonnes of NOx, 0.2 million of SOx and 0.03 million tonnes of PM10 in 2011. Around 85% of emissions come from containerships and tankers. Containerships have short port stays, but high emissions during these stays. Most of CO2 emissions in ports from shipping are in Asia and Europe (58%), but this share is low compared to their share of port calls (70%). European ports have much less emi...

  9. Lessons learned in terms of crisis management

    2006-01-01

    This document outlines that nobody was prepared to the crisis which occurred after the Chernobyl accident, whether in Russia, Europe or France. In order to illustrate the fact that crisis management has been different from one country to another, the report describes how the crisis has been managed in Norway (which has been quickly reached by fallouts and with a rather high level) and in Switzerland. It comments radioactivity measurements performed in France during spring 1986 by the SCPRI, the CEA and the ISPN. It discusses the lessons drawn in France in terms of emergency situation management regarding the protection of the population, crisis management, and the French post-accidental doctrine. It comments the lessons drawn in eastern European countries, with the cooperative implication of the IRSN. International projects are evoked: the Chernobyl Centre, the French-German Initiative, the European projects (EURANOS, NERIS, FARMING, STRATEGY, MOSES and SAMEN)

  10. ELPSA as A Lesson Design Framework

    Tom Lowrie

    2015-07-01

    Full Text Available This paper offers a framework for mathematics lesson design that is consistent with the way we learn about, and discover, most things in life. In addition, the framework provides a structure for identifying how mathematical concepts and understanding are acquired and developed. This framework is called ELPSA and represents five learning components, namely: Experience, Language, Pictorial, Symbolic and Applications. This framework has been used in developing lessons and teacher professional programs in Indonesia since 2012 in cooperation with the World Bank. This paper describes the theory that underlines the framework in general and in relation to each inter-connected component. Two explicit learning sequences for classroom practice are described, associated with Pythagoras theorem and probability. This paper then concludes with recommendations for using ELPSA in various institutional contexts.

  11. WHC significant lessons learned 1993--1995

    Bickford, J.C.

    1997-12-12

    A lesson learned as defined in DOE-STD-7501-95, Development of DOE Lessons Learned Programs, is: A ``good work practice`` or innovative approach that is captured and shared to promote repeat applications or an adverse work practice or experience that is captured and shared to avoid a recurrence. The key word in both parts of this definition is ``shared``. This document was published to share a wide variety of recent Hanford experiences with other DOE sites. It also provides a valuable tool to be used in new employee and continuing training programs at Hanford facilities and at other DOE locations. This manual is divided into sections to facilitate extracting appropriate subject material when developing training modules. Many of the bulletins could be categorized into more than one section, however, so examination of other related sections is encouraged.

  12. Rock slopes and reservoirs - lessons learned

    Moore, D.P.

    1999-01-01

    Lessons learned about slope stability in the course of four decades of monitoring, and in some cases stabilizing, slopes along British Columbia's hydroelectric reservoirs are discussed. The lessons are illustrated by short case histories of some of the more important slopes such as Little Chief Slide, Dutchman's Ridge, Downie Slide, Checkerboard Creek and Wahleach. Information derived from the monitoring and other investigations are compared with early interpretations of geology and slope performance. The comparison serves as an indicator of progress in slope stability determination and as a measure of the value of accumulated experience in terms of the potential consequences to safety and cost savings over the long life-span of hydroelectric projects.14 refs., 2 tabs., 15 figs

  13. Cryptography and the Internet: lessons and challenges

    McCurley, K.S.

    1996-12-31

    The popularization of the Internet has brought fundamental changes to the world, because it allows a universal method of communication between computers. This carries enormous benefits with it, but also raises many security considerations. Cryptography is a fundamental technology used to provide security of computer networks, and there is currently a widespread engineering effort to incorporate cryptography into various aspects of the Internet. The system-level engineering required to provide security services for the Internet carries some important lessons for researchers whose study is focused on narrowly defined problems. It also offers challenges to the cryptographic research community by raising new questions not adequately addressed by the existing body of knowledge. This paper attempts to summarize some of these lessons and challenges for the cryptographic research community.

  14. A Lesson in Knitting [In Bulgarian

    R. Pankova - Karadjova

    2016-11-01

    Full Text Available This is a non-fiction story about a grandmother teaching her six-year-old granddaughter how to knit. The child helps to wind the yarn into a ball and then patiently follows her granny's instructions, making stitch after stitch. The little girl's work is often uneven and is gently corrected. However, the small piece the child had knitted is used to patch up a tear in her grandfather's woolen glove. The lesson in knitting is transformed into a lesson in appreciation of one's work, no matter how small and insignificant it may seem. The narrative is permeated with the love between the grandmother and the child, who is the writer of the story.

  15. Material science lesson from the biological photosystem.

    Kim, Younghye; Lee, Jun Ho; Ha, Heonjin; Im, Sang Won; Nam, Ki Tae

    2016-01-01

    Inspired by photosynthesis, artificial systems for a sustainable energy supply are being designed. Each sequential energy conversion process from light to biomass in natural photosynthesis is a valuable model for an energy collection, transport and conversion system. Notwithstanding the numerous lessons of nature that provide inspiration for new developments, the features of natural photosynthesis need to be reengineered to meet man's demands. This review describes recent strategies toward adapting key lessons from natural photosynthesis to artificial systems. We focus on the underlying material science in photosynthesis that combines photosystems as pivotal functional materials and a range of materials into an integrated system. Finally, a perspective on the future development of photosynthesis mimetic energy systems is proposed.

  16. TMI-2 lessons have been learned

    Long, R.L.

    1994-01-01

    This paper is an introduction to the more detailed papers which are presented in this session titled ''Advanced Light Water Reactors -- 15 Years After TMI.'' Many of the advances in the design, operation and maintenance of nuclear power plants are the direct result of applying lessons learned from the 1979 TMI-2 accident. The authors believe the ''reality awakening'' which occurred following the accident should never be forgotten. Thus, this paper briefly reviews the TMI-2 accident and identifies the broad lessons learned following the accident. Then it describes briefly some indicators which show the very impressive improvements in nuclear power plant performance that have occurred over the past 10-15 years. This sets the stage for Dr. Ransom's paper which shows the continuing need for nuclear power, Dr. Beckjord's paper which describes the ''final'' TMI-2 research project and the subsequent papers which focus on advanced light water reactor developments

  17. Implementing greenhouse gas trading in Europe. Lessons from economic literature and international experiences

    Boemare, Catherine; Quirion, Philippe

    2002-01-01

    The European Commission (document COM (2001) 581) has recently presented a directive proposal to the European Parliament and Council in order to implement a greenhouse gas emission trading scheme. If this proposal survives the policy process, it will create the most ambitious trading system ever implemented. However, the legislative process is an opportunity for various interest groups to amend environmental policies, which as a result generally deviate further from what economic literature proposes. A close look at implemented emission trading schemes, stressing their discrepancies with economic literature requests, is thus useful to increase the chances of forthcoming emission trading schemes to go through the political process. We thus review ten emission trading systems, which are either implemented or at an advanced stage of the policy process. We draw attention to major points to be aware of when designing an emission trading system: sectoral and spatial coverage, permits allocation, temporal flexibility, trading organisation, monitoring, enforcement, compliance, and the harmonisation vs. subsidiarity issue. The aim is to evaluate how far experiences in emission trading move away from theory and why. We then provide some lessons and recommendations on how to implement a greenhouse gas emission trading program in Europe. We identify some pros of the Commission proposal (spatial and sectoral coverage, temporal flexibility, trading organisation, compliance rules), some potential drawbacks (allocation rules, monitoring and enforcement) and items on which further guidance is needed (monitoring and allocation rules). Lastly, the European Commission should devote prominent attention to the US NO X Ozone Transport Commission budget program, as the only example of integration between the federal and state levels

  3. Measuring and controlling greenhouse gas emissions

    Bourrier, Herve; LAFONT, Bruno; Fischer, Severin; Leonard, Damien; Tutenuit, Claire

    2011-05-01

    As providing a reporting of their greenhouse gas emissions has become mandatory for a large number of French companies, this publication proposes a methodology to perform an assessment or measurement, and a control of such emissions. In its first part, it explains why measurements are required: indication of concerned gases, international consensus to limit temperature rise, definition and chronology of the main steps adopted at the international level and which must be considered in the approach adopted by enterprises in this respect. It outlines the benefits of such a measurement for the enterprise in terms of competitiveness, personnel commitment, new markets and products, image, compliance with the law, operational and financial aspects, and so on. It identifies the various stakeholders to be informed: civil society, financial community, public authorities, clients and consumers, personnel, suppliers. It outlines the diversity and evolution of legal frameworks at the international level as well as at national levels. While evoking many examples of French companies (SNCF, EDF, Seche Environnement, RTE, Michelin, Arcelormittal, AREVA, Air France, EADS-Airbus, AXA, Veolia, and so on), the next part addresses how to measure emissions. It outlines the complexity of the methodological landscape with its various criteria, evokes the various existing standards, outlines the distinction between organisation-based, product-based and project-based approaches, and the distinction between direct and indirect emissions in relationship with the notion of scope. It comments the existence of sector-based methodologies and guidelines, and discusses some difficulties and methodological decisions. The third part proposes some lessons learned from the experience which could lead to a harmonisation of methodologies, proposes a synthesis of reporting approaches, outlines risks and opportunities related to communication

  15. Organizational safety factors research lessons learned

    Ryan, T.G.

    1995-01-01

    This Paper reports lessons learned and state of knowledge gained from an organizational factors research activity involving commercial nuclear power plants in the United States, through the end of 1991, as seen by the scientists immediately involved in the research. Lessons learned information was gathered from the research teams and individuals using a question and answer format. The following five questions were submitted to each team and individual: (1) What organizational factors appear to influence safety performance in some systematic way, (2) Should organizational factors research focus at the plant level, or should it extend beyond the plant level to the parent company, rate setting commissions, regulatory agencies, (3) How important is having direct access to plants for doing organizational factors research, (4) What lessons have been learned to date as the result of doing organizational factors research in a nuclear regulatory setting, and (5) What organizational research topics and issues should be pursued in the future? Conclusions based on the responses provided for this report are that organizational factors research can be conducted in a regulatory setting and produce useful results. Technologies pioneered in other academic, commercial, and military settings can be adopted for use in a nuclear regulatory setting. The future success of such research depends upon the cooperation of regulators, contractors, and the nuclear industry

  16. Enhancing mathematics teachers' quality through Lesson Study.

    Lomibao, Laila S

    2016-01-01

    The efficiency and effectivity of the learning experience is dependent on the teacher quality, thus, enhancing teacher's quality is vital in improving the students learning outcome. Since, the usual top-down one-shot cascading model practice for teachers' professional development in Philippines has been observed to have much information dilution, and the Southeast Asian Ministers of Education Organization demanded the need to develop mathematics teachers' quality standards through the Southeast Asia Regional Standards for Mathematics Teachers (SEARS-MT), thus, an intensive, ongoing professional development model should be provided to teachers. This study was undertaken to determine the impact of Lesson Study on Bulua National High School mathematics teachers' quality level in terms of SEARS-MT dimensions. A mixed method of quantitative-qualitative research design was employed. Results of the analysis revealed that Lesson Study effectively enhanced mathematics teachers' quality and promoted teachers professional development. Teachers positively perceived Lesson Study to be beneficial for them to become a better mathematics teacher.

  17. Research Data Curation Pilots: Lessons Learned

    David Minor

    2014-07-01

    Full Text Available In the spring of 2011, the UC San Diego Research Cyberinfrastructure (RCI Implementation Team invited researchers and research teams to participate in a research curation and data management pilot program. This invitation took the form of a campus-wide solicitation. More than two dozen applications were received and, after due deliberation, the RCI Oversight Committee selected five curation-intensive projects. These projects were chosen based on a number of criteria, including how they represented campus research, varieties of topics, researcher engagement, and the various services required. The pilot process began in September 2011, and will be completed in early 2014. Extensive lessons learned from the pilots are being compiled and are being used in the on-going design and implementation of the permanent Research Data Curation Program in the UC San Diego Library. In this paper, we present specific implementation details of these various services, as well as lessons learned. The program focused on many aspects of contemporary scholarship, including data creation and storage, description and metadata creation, citation and publication, and long term preservation and access. Based on the lessons learned in our processes, the Research Data Curation Program will provide a suite of services from which campus users can pick and choose, as necessary. The program will provide support for the data management requirements from national funding agencies.

  18. Low level waste shipment accident lessons learned

    Rast, D.M.; Rowe, J.G.; Reichel, C.W.

    1995-01-01

    On October 1, 1994 a shipment of low-level waste from the Fernald Environmental Management Project, Fernald, Ohio, was involved in an accident near Rolla, Missouri. The accident did not result in the release of any radioactive material. The accident did generate important lessons learned primarily in the areas of driver and emergency response communications. The shipment was comprised of an International Standards Organization (ISO) container on a standard flatbed trailer. The accident caused the low-level waste package to separate from the trailer and come to rest on its top in the median. The impact of the container with the pavement and median inflicted relatively minor damage to the container. The damage was not substantial enough to cause failure of container integrity. The success of the package is attributable to the container design and the packaging procedures used at the Fernald Environmental Management Project for low-level waste shipments. Although the container survived the initial wreck, is was nearly breached when the first responders attempted to open the ISO container. Even though the container was clearly marked and the shipment documentation was technically correct, this information did not identify that the ISO container was the primary containment for the waste. The lessons learned from this accident have DOE complex wide applicability. This paper is intended to describe the accident, subsequent emergency response operations, and the lessons learned from this incident

  20. BP's emissions trading system

    Victor, David G.; House, Joshua C.

    2006-01-01

    Between 1998 and 2001, BP reduced its emissions of greenhouse gases by more than 10%. BP's success in cutting emissions is often equated with its use of an apparently market-based emissions trading program. However no independent study has ever examined the rules and operation of BP's system and the incentives acting on managers to reduce emissions. We use interviews with key managers and with traders in several critical business units to explore the bound of BP's success with emissions trading. No money actually changed hands when permits were traded, and the main effect of the program was to create awareness of money-saving emission controls rather than strong price incentives. We show that the trading system did not operate like a 'textbook' cap and trade scheme. Rather, the BP system operated much like a 'safety valve' trading system, where managers let the market function until the cost of doing so surpassed what the company was willing to tolerate

  1. Prompt neutron emission

    Sher, R.

    1959-01-01

    It is shown that Ramanna and Rao's tentative conclusion that prompt fission neutrons are emitted (in the fragment system) preferentially in the direction of fragment motion is not necessitated by their angular distribution measurements, which are well explained by the usual assumptions of isotropic emission with a Maxwell (or Maxwell-like) emission spectrum. The energy distribution (Watt spectrum) and the angular distribution, both including the effects of anisotropic emission, are given. (author) [fr

  2. Radio emission from Jupiter

    Velusamy, T.

    1976-01-01

    The basic features of the different radio emissions from the planet Jupiter are reviewed. These radio emissions characterized into three types as thermal, decimetric and decametric, are discussed. The coherent emission mechanism for the origin of the decametric bursts and the acceleration mechanism for relativistic electrons in the decimetric radiation have not been properly understood. The emissions are much related to the magnetic field of Jupiter. The system III rotation period for Jupiter has been calculated as 092 55 m 29.74 S. (A.K.)

  5. Emissions Trading: The Ugly Duckling in European Climate Policy?

    Wraake, Markus

    2009-07-15

    The initial years of the European Union's Emissions Trading System (EU ETS) have provided a large-scale testing ground for trading of a new environmental commodity, carbon dioxide. This paper provides an overview of the origins and characteristics of the EU ETS. It then goes on to analyse the most contentious issues that have been discussed in the economics literature and in the public debate surrounding the trading system. The lessons learned are diverse and not all experiences are positive. Nevertheless, invaluable information has been gained from the EU ETS and policy makers in Europe and elsewhere would be wise to make use of it, be they supporters of emissions trading or sceptics to such policies. The paper concludes with a look toward the future, highlighting some upcoming revisions of the EU ETS and at what issues remain unresolved

    CHARLIE P. NACARIO

    2014-08-01

    Full Text Available This study determined the effectiveness of the lessons in Chemistry integrating UNESCO ICT-based instructional material on the achievement of Chemistry students at Central Bicol State University of Agriculture. It aimed to identify lessons that may be developed integrating UNESCO ICT-based instructional materials, determine the effect of the developed lessons using the material on: conceptual understanding; science process skills; and attitude towards chemistry and gather insights from the experiences of the students and teacher. The study used the single group pretest and posttest experimental design. Descriptive, quantitative and qualitative techniques were also utilized. Quantitative data were taken from the pretest-posttest results on the Test on Conceptual Understanding, Science Process Skills and Chemistry Attitudinaire. Qualitative data were drawn from the experts’ assessment of the developed lessons and research instruments, and the insights of students and teacher. The developed lessons integrating UNESCO ICT-based instructional materials were Atomic Model and Structure, Periodic Table of Elements, Chemical Bonding, and Balancing Chemical Equation. These lessons increased the conceptual understanding of the students by topic and skill from very low mastery to average mastery level. The students have slightly improved along the different science process skills. After teaching the lessons, the students’ attitude also improved. The students became more motivated and interested in Chemistry and the lessons were student centered and entailed teacher’s competence and flexibility in computer use.

  8. Outsourcing CO2 Emissions

    Davis, S. J.; Caldeira, K. G.

    2009-12-01

    CO2 emissions from the burning of fossil fuels are the primary cause of global warming. Much attention has been focused on the CO2 directly emitted by each country, but relatively little attention has been paid to the amount of emissions associated with consumption of goods and services in each country. This consumption-based emissions inventory differs from the production-based inventory because of imports and exports of goods and services that, either directly or indirectly, involved CO2 emissions. Using the latest available data and reasonable assumptions regarding trans-shipment of embodied carbon through third-party countries, we developed a global consumption-based CO2 emissions inventory and have calculated associated consumption-based energy and carbon intensities. We find that, in 2004, 24% of CO2 emissions are effectively outsourced to other countries, with much of the developed world outsourcing CO2 emissions to emerging markets, principally China. Some wealthy countries, including Switzerland and Sweden, outsource over half of their consumption-based emissions, with many northern Europeans outsourcing more than three tons of emissions per person per year. The United States is both a big importer and exporter of emissions embodied in trade, outsourcing >2.6 tons of CO2 per person and at the same time as >2.0 tons of CO2 per person are outsourced to the United States. These large flows indicate that CO2 emissions embodied in trade must be taken into consideration when considering responsibility for increasing atmospheric greenhouse gas concentrations.

  12. Carbon Monitoring System Applications Framework: Lessons Learned from Stakeholder Engagement Activities

    Sepulveda Carlo, E.; Escobar, V. M.; Delgado Arias, S.; Forgotson, C.

    2017-12-01

    The NASA Carbon Monitoring System initiated by U.S. Congress in 2010 is developing products that characterize and quantify carbon sources and sinks in the United States and the global tropics. In 2013, an applications effort was selected to engage potential end users and gather feedback about their data needs. For the past four years the CMS applications efforts has expanded and implemented a number of strategies to connect carbon scientists to decision-makers, contributing to the societal benefits of CMS data products. The applications efforts use crowd sourcing to collects feedback from stakeholders on challenges and lessons learned in the use of CMS data products. Some of the most common data needs from engaged organizations include above and below-ground biomass and fluxes in forestlands and wetlands, and greenhouse gas (GHG) emissions across all land use/cover and land use changes. Stakeholder organizations' needs for CMS data products support national GHG inventories following the Paris Agreement, carbon markets, and sub-national natural resources management and policies. The lessons learned report presents stakeholder specific applications, challenges, and successes from using CMS data products. To date, the most common uses of CMS products include: conservation efforts, emissions inventory, forestry and land cover applications, and carbon offset projects. The most common challenges include: the need for familiar and consistent products over time, budget constraints, and concern with uncertainty of modeled results. Recurrent recommendations from stakeholder indicate that CMS should provide high resolution (30m) and frequent data products updates (annually). The applications efforts have also helped identified success stories from different CMS projects, including the development of the GHG emissions inventory from Providence, RI, the improvement of the U.S. GHG Inventory though the use of satellite data, and the use of high resolution canopy cover maps for

    2000-01-01

    MONJU sodium leak accident was a small accident with a large public impact. There was no injures or exposure to radiation, nor was there any loss of safety function such as reactor shutdown or reactor cooling. On the contrary a social impact is considerably large, whereby the plant remains shutdown. This paper describes the lessons learned from the accident, i.e. the impact of the accident and its cause, and the features on risk management in view of social aspect as well as technical aspect.

    1998-01-01

    A review of competitive retail electricity markets in Argentina, New Zealand, Australia and California were discussed, highlighting lessons for Alberta policy makers, market designers and electricity retailers. Some of the emerging strategies in the retail electricity marketplace such as horizontal integration, generation retailing, defensive retailing and virtual vertical integration were explored. Emphasis was on showing that electricity retailing is not an easy business. It is a business for large and existing players, and although horizontal and vertical integration have growth and profit potential, there are also risks

  4. The Fernald Closure Project: Lessons Learned

    Murphy, Cornelius M.; Carr, Dennis

    2008-01-01

    For nearly 37 years, the U.S. Department of Energy site at Fernald - near Cincinnati, Ohio - produced 230,000 metric tons (250,000 short tons) of high-purity, low-enriched uranium for the U.S. Defense Program, generating more than 5.4 million metric tons (6 million short tons) of liquid and solid waste as it carried out its Cold War mission. The facility was shut down in 1989 and clean up began in 1992, when Fluor won the contract to clean up the site. Cleaning up Fernald and returning it to the people of Ohio was a $4.4 billion mega environmental-remediation project that was completed in October 2006. Project evolved through four phases: - Conducting remedial-investigation studies to determine the extent of damage to the environment and groundwater at, and adjacent to, the production facilities; - Selecting cleanup criteria - final end states that had to be met that protect human health and the environment; - Selecting and implementing the remedial actions to meet the cleanup goals; - Executing the work in a safe, compliant and cost-effective manner. In the early stages of the project, there were strained relationships - in fact total distrust - between the local community and the DOE as a result of aquifer contamination and potential health effects to the workers and local residents. To engage citizens and interested stakeholders groups in the decision-making process, the DOE and Fluor developed a public-participation strategy to open the channels of communication with the various parties: site leadership, technical staff and regulators. This approach proved invaluable to the success of the project, which has become a model for future environmental remediation projects. This paper will summarize the history and shares lessons learned: the completion of the uranium-production mission to the implementation of the Records of Decision defining the cleanup standards and the remedies achieved. Lessons learned fall into ten categories: - Regulatory approach with end

  5. Lessons Learned from Environmental Remediation Programmes

    NONE

    2014-03-15

    Several remediation projects have been developed to date, and experience with these projects has been accumulated. Lessons learned span from non-technical to technical aspects, and need to be shared with those who are beginning or are facing the challenge to implement environmental remediation works. This publication reviews some of these lessons. The key role of policy and strategies at the national level in framing the conditions in which remediation projects are to be developed and decisions made is emphasized. Following policy matters, this publication pays attention to the importance of social aspects and the requirement for fairness in decisions to be made, something that can only be achieved with the involvement of a broad range of interested parties in the decision making process. The publication also reviews the funding of remediation projects, planning, contracting, cost estimates and procurement, and issues related to long term stewardship. Lessons learned regarding technical aspects of remediation projects are reviewed. Techniques such as the application of cover systems and soil remediation (electrokinetics, phytoremediation, soil flushing, and solidification and stabilization techniques) are analysed with respect to performance and cost. After discussing soil remediation, the publication covers issues associated with water treatment, where techniques such as ‘pump and treat’ and the application of permeable barriers are reviewed. Subsequently, there is a section dedicated to reviewing briefly the lessons learned in the remediation of uranium mining and processing sites. Many of these sites throughout the world have become orphaned, and are waiting for remediation. The publication notes that little progress has been made in the management of some of these sites, particularly in the understanding of associated environmental and health risks, and the ability to apply prediction to future environmental and health standards.

We review the lessons learned from recent observations and from theory and identify outstanding questions and areas where more theoretical and observational work is needed. We also consider upcoming observing facilities that can be used to study tidal disruption events and speculate what these new facilities may contribute to the field.

  7. [Lessons from a heart valve prosthesis controversy].

    Vandenbroucke, J P; Grobbee, D E

    1998-07-18

    Two lessons are to be learnt from the Björk-Shiley heart valve prosthesis tragedy. In the first place pharmacoepidemiologic studies are seriously hampered by recent privacy legislation. Individual patients carrying such a prosthesis cannot be traced and advised as to their health risks any more, because their legal autonomy has to be respected. This is clearly not to their advantage. In the second place the atmosphere of marketing and litigation and the increasing dependency of researchers on money from sources with conflicting interests is not conducive to a well-informed and balanced judgement of the epidemiological evidence of safety and efficacy of medical treatments.

    Madden, D.

    2009-01-01

    This paper examines the lessons to be learnt from the organ retention controversy in the Republic of Ireland. The paper emphasises the importance of good communication between clinicians and families of deceased persons and a move away from a medical culture based on paternalism to a partnership approach between clinicians and patients based on mutual trust and understanding. A model of authorisation rather than consent is proposed as the way forward for dealing with the difficult and traumatic experience of asking families for permission to carry out a post mortem examination on their deceased child.

  11. Observed Barium Emission Rates

    Stenbaek-Nielsen, H. C.; Wescott, E. M.; Hallinan, T. J.

    1993-01-01

    The barium releases from the CRRES satellite have provided an opportunity for verifying theoretically calculated barium ion and neutral emission rates. Spectra of the five Caribbean releases in the summer of 1991 were taken with a spectrograph on board a U.S. Air Force jet aircraft. Because the line of sight release densities are not known, only relative rates could be obtained. The observed relative rates agree well with the theoretically calculated rates and, together with other observations, confirm the earlier detailed theoretical emission rates. The calculated emission rates can thus with good accuracy be used with photometric observations. It has been postulated that charge exchange between neutral barium and oxygen ions represents a significant source for ionization. If so. it should be associated with emissions at 4957.15 A and 5013.00 A, but these emissions were not detected.

  13. The California experience : lessons learned and prospects for the future

    Levin, J. [AC Transit, Oakland, CA (United States)

    2007-07-01

    AC Transit operates 650 hydrogen-powered mass transit buses that serve 1.5 million people in 13 cities in California. This presentation discussed the impact of the buses on public health, quality of life and cost savings. Hydrogen has been touted as a diversified and renewable energy supply that can provide energy independence and reduction in global warming. Mass transit systems have proven to be well suited for testing the limits of hydrogen-powered vehicles primarily because of the centralized fueling and maintenance structure. AC Transit began ZEbus testing in November 1999 and became involved in the California Fuel Cell Partnership in 2000. The NeBus test was performed in 2000, followed by the ISE/UTC Thor Bus in 2003/2004. The governor's inauguration of the zero emission buses was in January 2007. The lessons learned from the California experience were: (1) motivation must be for the right reason, (2) a champion is required, (3) community and political support is required, (4) capital investment is required, (5) a strong management team is required, (6) partners must be chosen wisely, (7) the end user or customer must be allowed to drive the design, (8) inform the public about plans, (9) evaluation is essential to industry-wide application, (10) all resources must be considered for outreach and education, (11) optimism is required to surpass challenges, (12) the technology should be promoted for future generations. The presentation concluded with comments on market value of hydrogen and fuel cell vehicles, their fuel efficiency, reliability and durability. tabs., figs.

  14. Motivation Matters: Lessons for REDD+ Participatory Measurement, Reporting and Verification from Three Decades of Child Health Participatory Monitoring in Indonesia.

    Ekowati, Dian; Hofstee, Carola; Praputra, Andhika Vega; Sheil, Douglas

    2016-01-01

    Participatory Measurement, Reporting and Verification (PMRV), in the context of reducing emissions from deforestation and forest degradation with its co-benefits (REDD+) requires sustained monitoring and reporting by community members. This requirement appears challenging and has yet to be achieved. Other successful, long established, community self-monitoring and reporting systems may provide valuable lessons. The Indonesian integrated village healthcare program (Posyandu) was initiated in the 1980s and still provides effective and successful participatory measurement and reporting of child health status across the diverse, and often remote, communities of Indonesia. Posyandu activities focus on the growth and development of children under the age of five by recording their height and weight and reporting these monthly to the Ministry of Health. Here we focus on the local Posyandu personnel (kaders) and their motivations and incentives for contributing. While Posyandu and REDD+ measurement and reporting activities differ, there are sufficient commonalities to draw useful lessons. We find that the Posyandu kaders are motivated by their interests in health care, by their belief that it benefits the community, and by encouragement by local leaders. Recognition from the community, status within the system, training opportunities, competition among communities, and small payments provide incentives to sustain participation. We examine these lessons in the context of REDD+.

  16. Assessing environmental impacts of offshore wind farms: lessons learned and recommendations for the future.

    Bailey, Helen; Brookes, Kate L; Thompson, Paul M

    2014-01-01

    Offshore wind power provides a valuable source of renewable energy that can help reduce carbon emissions. Technological advances are allowing higher capacity turbines to be installed and in deeper water, but there is still much that is unknown about the effects on the environment. Here we describe the lessons learned based on the recent literature and our experience with assessing impacts of offshore wind developments on marine mammals and seabirds, and make recommendations for future monitoring and assessment as interest in offshore wind energy grows around the world. The four key lessons learned that we discuss are: 1) Identifying the area over which biological effects may occur to inform baseline data collection and determining the connectivity between key populations and proposed wind energy sites, 2) The need to put impacts into a population level context to determine whether they are biologically significant, 3) Measuring responses to wind farm construction and operation to determine disturbance effects and avoidance responses, and 4) Learn from other industries to inform risk assessments and the effectiveness of mitigation measures. As the number and size of offshore wind developments increases, there will be a growing need to consider the population level consequences and cumulative impacts of these activities on marine species. Strategically targeted data collection and modeling aimed at answering questions for the consenting process will also allow regulators to make decisions based on the best available information, and achieve a balance between climate change targets and environmental legislation.

  17. CLIL in physics lessons at grammar school

    Štefančínová, Iveta; Valovičová, Ľubomíra

    2017-01-01

    Content and Language Integrated Learning (CLIL) is one of the most outstanding approaches in foreign language teaching. This teaching method has promising prospects for the future of modern education as teaching subject and foreign languages are combined to offer a better preparation for life in Europe, especially when the mobility is becoming a highly significant factor of everyday life. We realized a project called Foreign languages in popularizing science at grammar school. Within the project five teachers with approbation subjects of English, French, German and Physics attended the methodological courses abroad. The teachers applied the gained experience in teaching and linking science teaching with the teaching of foreign languages. Outputs of the project (e.g. English-German-French-Slovak glossary of natural science terminology, student activity sheets, videos with natural science orientation in a foreign language, physical experiments in foreign languages, multimedia fairy tales with natural contents, posters of some scientists) are prepared for the CLIL-oriented lessons. We collected data of the questionnaire for students concerning attitude towards CLIL. The questionnaire for teachers showed data about the attitude, experience, and needs of teachers employing CLIL in their lessons.

  18. Lessons learned from accidents in radiotherapy

    Ortiz-Lopez, P.; Haywood, J.

    1996-01-01

    Radiotherapy is the only application of radiation which intentionally delivers very high doses to humans. A gross deviation from the prescribed dose or dose distribution can have severe, or even fatal consequences. Since the patient is placed directly in the beam or sources are inserted in the body, any mistake made with the beam or the sources leads almost certainly to an accidental exposure. Lessons learned from previous incidents can be used to test the vulnerability of a given facility, provided that these are adequately disseminated. The purpose of this paper is to present a summary of the lessons learned from a relatively large sample of events. The analysis has been presented as a short description followed by an identification of the triggering event and the contributing factors. These have been grouped as follows: errors in commissioning or calibration machines and sources affecting many patients; mistakes affecting individual patients such as irradiating the wrong patient, the wrong, field or site, and mistakes when entering data into or reading from the patient's chart; error due to unusual treatments or situations; equipment failure and human machine problems, including maintenance.

  19. Arms control: moral, political and historical lesson

    Thompson, K.W.

    1990-01-01

    Many of the world's most influential policy-makers and analysts view arms control as a scientific and technological problem. They measure a nation's nuclear power exclusively by megatonnage and throw-weights leaving the intangible elements of military and political power to philosophers and historians. They tend to ignore the human and qualitative aspects of power. This is a book that shift the emphasis to aspects of the nuclear problem which are sometimes overlooked. Basically, these elements are bound up in the moral, political, and historical lessons of the nuclear age. Nonquantitative factors have been central to studies of national defense and military power since the rise of the modern nation state system. However, most students of present-day nuclear weapons tend to stress their revolutionary character. Because they are considered wholly unique, analysts tend to write about them in a historical and apolitical terms. One purpose of the collection of papers in this little volume is to redirect attention to the moral, political, and historical lessons that the nuclear age presents. What most distinguishes the writings of contributors to this volume is their use of certain well-established principles and concepts long acknowledged in military and foreign policy analysis. Thus Father Hehir asks many of the same questions that students of ethics and foreign policy have asked for four hundred years

  20. Dynasting Theory: Lessons in learning grounded theory

    Johnben Teik-Cheok Loy, MBA, MTS, Ph.D.

    2011-06-01

    Full Text Available This article captures the key learning lessons gleaned from the author’s experience learning and developing a grounded theory for his doctoral dissertation using the classic methodology as conceived by Barney Glaser. The theory was developed through data gathered on founders and successors of Malaysian Chinese family-own businesses. The main concern for Malaysian Chinese family businesses emerged as dynasting . the building, maintaining, and growing the power and resources of the business within the family lineage. The core category emerged as dynasting across cultures, where founders and successors struggle to transition from traditional Chinese to hybrid cultural and modernized forms of family business from one generation to the next. The key learning lessons were categorized under five headings: (a sorting through different versions of grounded theory, (b educating and managing research stakeholders, (c embracing experiential learning, (d discovering the core category: grounded intuition, and (e recognizing limitations and possibilities.Keywords: grounded theory, learning, dynasting, family business, Chinese

  1. Governing nanobiotechnology: lessons from agricultural biotechnology regulation

    Johnson, Robbin S.

    2011-01-01

    This article uses lessons from biotechnology to help inform the design of oversight for nanobiotechnology. Those lessons suggest the following: first, oversight needs to be broadly defined, encompassing not just regulatory findings around safety and efficacy, but also public understanding and acceptance of the technology and its products. Second, the intensity of scrutiny and review should reflect not just risks but also perceptions of risk. Finally, a global marketplace argues for uniform standards or commercially practical solutions to differences in standards. One way of designing oversight to achieve these purposes is to think about it in three phases—precaution, prudence, and promotion. Precaution comes early in the technology or product’s development and reflects real and perceived uncertainties. Prudence governs when risks and hazards have been identified, containment approaches established, and benefits broadly defined. Transparency and public participation rise to the fore. The promotional phase moves toward shaping public understanding and acceptance and involves marketing issues rather than safety ones. This flexible, three-phase approach to oversight would have avoided some of the early regulatory problems with agricultural biotechnology. It also would have led to a more risk-adjusted pathway to regulatory approval. Furthermore, it would avoid some of the arbitrary, disruptive marketing issues that have arisen.

  2. 10 lessons learned by a misguided physician.

    Levin, Barry E

    2017-07-01

    It was a great and humbling honor to receive the 2016 Distinguished Career Award from my SSIB colleagues. This paper summarizes the major points of my DCA talk at the 2016 annual meeting. It is a reflection on my 50year medical and research career and 10 lessons I have learned over those years which might be of help to young investigators near the beginning of their own research careers. These lessons include: the value of being receptive to the opportunities provided you; how clinician-scientists can serve as critical role models for young investigators like me and a history of how my career developed as a result of their influence; the importance of carefully examining your own data, particularly when it doesn't agree with your preconceived ideas; the critical role that students, postdocs and PhD (and even veterinarian) colleagues can play in developing one's career; the likelihood that your career path will have many interesting twists and turns determined by changes in your own scientific interests and how rewarding various areas of research focus are to you; the importance of building a close-knit laboratory staff family; the fact that science and romance can mix. Finally, I offer 3 somewhat self-evident free pieces of advice for building and maintaining a rewarding career. Copyright © 2016 Elsevier Inc. All rights reserved.

  3. Lessons learned on stakeholder issues in decommissioning

    O'Sullivan, P.; Pescatore, C.

    2008-01-01

    Issues of public concern during decommissioning and dismantling (D and D) are partly the same and partly different from those of the preceding phases (planning, construction and operation). While in the course of construction and operation the main challenges include meeting expectations of a higher quality of life, accommodating a growing population, mitigating construction nuisances, and assuring the safe operation of the facility, the main concerns in the D and D phase are decreasing employment rate, the eventual reduction of revenues for the municipality, the future use of the affected land and negative social impacts (e.g., out-migration). The decommissioning phase is characterised by heterogeneity of stakeholder interests and values, difficulties of reaching consensus or compromise, and difficulties in connection with the harmonization of energy production, environmental protection and sustainable socio-economic development considerations. Typically, there might also be tensions between local and regional decisions. As in other phases, the building of trust between stakeholder is crucial from the point of view of conflict management, and social lessons learnt from the siting and developments of nuclear facilities are widely applicable in the field of D and D as well. A review is presented of major lessons to be learnt from NEA activities in the field of decommissioning and stakeholder involvement. (author)

    2001-01-01

    Information on the emissions and energy consumption of different vehicles per transported amount of goods has up to last years been minimal. The unit emissions mean the amount of harmful compounds in the flue gases of a vehicle per service, time or energy unit. National three-year MOBILE 2-research program, started in 1999, determines the unit emissions of all the traffic sectors in Finland. VTT Building and Transport mainly carry out the research, but the Institute of Transportation Engineering of the Tampere University of Technology (TTKK) is responsible for a part of the research. The objective of the project is to create common rules for the determination of unit emissions values, and to determine the best possible values for Finnish conditions. Unit emission data is mainly needed for evaluation of the environmental impacts of production plants and other activities containing transportation of commodities. At the web sites of VTT Building and Transport there are about 60 pages of text and tables (about 4000 values) on unit emissions. The URL of the pages is http://www.vtt.fi/rte/projects/lipastoe/index.htm. These web pages present data on all the transportation sectors (road, railroad, water and air transportation), most of the materials concerning road transportation. Following compounds and values are included: CO, HC, NO x , particulates, SO 2 , CO 2 and energy consumption. Methane and nitrous oxide emissions values have also been presented

  10. Development of short Indonesian lesson plan to improve teacher performance

    Yulianto, B.; Kamidjan; Ahmadi, A.; Asteria, P. V.

    2018-01-01

    The developmental research was motivated by the results of preliminary study through interviews, which revealed almost all of the teachers did not create lesson plan themselves. As a result of this load, the performance of the real learning in the classroom becomes inadequate. Moreover, when lesson plan was not made by teachers themselves, the learning process becomes ineffective. Therefore, this study designed to develop a prototype of the short lesson plan, in particular, Indonesian language teaching, and to investigate its effectiveness. The participants in the study were teachers who were trained through lesson study group to design short model’s lesson plan. Questionnaires and open-ended questions were used, and the quantitative and qualitative data obtained were analyzed accordingly. The analysis of the quantitative data, aided with SPSS, were frequency, percentage, and means, whereas the qualitative data were analyzed descriptively. The results showed that the teachers liked the model, and they were willing to design their own lesson plan. The observation data revealed that the classroom learning process became more interactive, and classroom atmosphere was more engaging and natural because the teachers did not stick to the lesson plan made by other teachers.

    It was broadcasted to all Cuba from March to December 2005, one lesson per week, transmitting three times each lesson, this means 90 hours of broadcasting. It was one of the courses of the Program "University for All", that Educative Channel produced. The Thematic: Sky Coordinates and Constellations; Astronomical Instruments; Solar System; Planets and their Moons; Comets, Asteroids and Meteoroids; Sun; Cosmic Environment and Space Weather; Stars; Galaxy and Quasars; Observable Universe; Life, Intelligent Life and Civilizations in the Universe; and History of Astronomy in Cuba. The professor staff was a group of 5 researchers of the Astronomy Department. They did an effort that each lesson had the best information level with a minimum of mathematical expressions. And were used more than 60 slides and various astronomical films fragments per lesson. To make one lesson was analyzed several astronomical films, selected a group of fragments and pre-edited into various blocks with the TV specialists, later a power point presentation was conformed using all available information on-line and bibliography. Then the lesson was recorded by the TV specialist at the Educative Channel and latter reviewed and improved by one AVID edition. The Course groundwork began in April 2003, with the first list of 12 lessons, later in June was increased to18 lessons, and started the work of "Tabloide" making; it is a journal-type book of 32 pages, equivalent to about 120 normal pages including 64 illustrations. At December 2004 the Course was increased to 30 lessons and the "Tabloide" was send to editor, later 200,000 exemplars was published. Many people followed Course and "Tabloide" was shopped in some months.

  15. Emission sources and quantities

    Heinen, B.

    1991-01-01

    The paper examines emission sources and quantities for SO 2 and NO x . Natural SO 2 is released from volcanic sources and to a much lower extent from marsh gases. In nature NO x is mainly produced in the course of the chemical and bacterial denitrification processes going on in the soil. Manmade pollutants are produced in combustion processes. The paper concentrates on manmade pollution. Aspects discussed include: mechanism of pollution development; manmade emission sources (e.g. industry, traffic, power plants and domestic sources); and emission quantities and forecasts. 11 refs., 2 figs., 5 tabs

  19. The application of micro-lesson in optics teaching

    Yuan, Suzhen; Mao, Xuefeng; Lu, Yongle; Wang, Yan; Luo, Yuan

    2017-08-01

    In order to improve students' ability on self-study, this paper discusses the application of micro-lesson as a supplementary way in the course of optics teaching. Both geometric optics and wave optics require a lot of demos, fortunately, micro-lesson just meets this requirement. Nowadays, college education focuses on quality education, so the new nurture scheme of most universities shortened the class hours. However, the development of students and the social needs also require students to have a solid foundation. The effective way to solve this contradiction is to improve the efficiency of classroom teaching and provide the repeatable learning form, micro-lesson.

    Positron emission tomography is an intrinsically tool that provide a unique and unparalleled approach for clinicians and researchers to interrogate the heart noninvasively. The ability to label substances of physiological interest with positron-emitting radioisotopes has permitted insight into normal blood flow and metabolism and the alterations that occur with disease states. Positron emission tomography of the heart has evolved as a unique, noninvasive approach for the assessment of myocardial perfusion, metabolism, and function. Because of the intrinsic quantitative nature of positron emission tomography measurements as well as the diverse compounds that can be labeled with positron- emitting radioisotopes, studies with positron emission tomography have provided rich insight into the physiology of the heart under diverse conditions

  6. Photon enhanced thermionic emission

    Schwede, Jared; Melosh, Nicholas; Shen, Zhixun

    2014-10-07

    Photon Enhanced Thermionic Emission (PETE) is exploited to provide improved efficiency for radiant energy conversion. A hot (greater than 200.degree. C.) semiconductor cathode is illuminated such that it emits electrons. Because the cathode is hot, significantly more electrons are emitted than would be emitted from a room temperature (or colder) cathode under the same illumination conditions. As a result of this increased electron emission, the energy conversion efficiency can be significantly increased relative to a conventional photovoltaic device. In PETE, the cathode electrons can be (and typically are) thermalized with respect to the cathode. As a result, PETE does not rely on emission of non-thermalized electrons, and is significantly easier to implement than hot-carrier emission approaches.

  13. Spent Fuel Storage Operation - Lessons Learned

    2013-12-01

    Experience gained in planning, constructing, licensing, operating, managing and modifying spent fuel storage facilities in some Member States now exceeds 50 years. Continual improvement is only achieved through post-project review and ongoing evaluation of operations and processes. This publication is aimed at collating and sharing lessons learned. Hopefully, the information provided will assist Member States that already have a developed storage capability and also those considering development of a spent nuclear fuel storage capability in making informed decisions when managing their spent nuclear fuel. This publication is expected to complement the ongoing Coordinated Research Project on Spent Fuel Performance Assessment and Research (SPAR-III); the scope of which prioritizes facility operational practices in lieu of fuel and structural components behaviour over extended durations. The origins of the current publication stem from a consultants meeting held on 10-12 December 2007 in Vienna, with three participants from the IAEA, Slovenia and USA, where an initial questionnaire on spent fuel storage was formulated (Annex I). The resultant questionnaire was circulated to participants of a technical meeting, Spent Fuel Storage Operations - Lessons Learned. The technical meeting was held in Vienna on 13-16 October 2008, and sixteen participants from ten countries attended. A consultants meeting took place on 18-20 May 2009 in Vienna, with five participants from the IAEA, Slovenia, UK and USA. The participants reviewed the completed questionnaires and produced an initial draft of this publication. A third consultants meeting took place on 9-11 March 2010, which six participants from Canada, Hungary, IAEA, Slovenia and the USA attended. The meeting formulated a second questionnaire (Annex II) as a mechanism for gaining further input for this publication. A final consultants meeting was arranged on 20-22 June 2011 in Vienna. Six participants from Hungary, IAEA, Japan

  14. Transient Infrared Emission Spectroscopy

    Jones, Roger W.; McClelland, John F.

    1989-12-01

    Transient Infrared Emission Spectroscopy (TIRES) is a new technique that reduces the occurrence of self-absorption in optically thick solid samples so that analytically useful emission spectra may be observed. Conventional emission spectroscopy, in which the sample is held at an elevated, uniform temperature, is practical only for optically thin samples. In thick samples the emission from deep layers of the material is partially absorbed by overlying layers.1 This self-absorption results in emission spectra from most optically thick samples that closely resemble black-body spectra. The characteristic discrete emission bands are severely truncated and altered in shape. TIRES bypasses this difficulty by using a laser to heat only an optically thin surface layer. The increased temperature of the layer is transient since the layer will rapidly cool and thicken by thermal diffusion; hence the emission collection must be correlated with the laser heating. TIRES may be done with both pulsed and cw lasers.2,3 When a pulsed laser is used, the spectrometer sampling must be synchronized with the laser pulsing so that only emission during and immediately after each laser pulse is observed.3 If a cw laser is used, the sample must move rapidly through the beam. The hot, transient layer is then in the beam track on the sample at and immediately behind the beam position, so the spectrometer field of view must be limited to this region near the beam position.2 How much self-absorption the observed emission suffers depends on how thick the heated layer has grown by thermal diffusion when the spectrometer samples the emission. Use of a pulsed laser synchronized with the spectrometer sampling readily permits reduction of the time available for heat diffusion to about 100 acs .3 When a cw laser is used, the heat-diffusion time is controlled by how small the spectrometer field of view is and by how rapidly the sample moves past within this field. Both a very small field of view and a

    Failure can be a major driver for the advance of any engineering discipline and Software Engineering is no exception. But failures are useful only if lessons are learned from them. In this article we aim to make a strong defence of, and set the requirements for, lessons learned systems for safety-critical software. We also present a prototype lessons learned system that includes many of the features discussed here. We emphasize that, apart from individual organizations, lessons learned systems should target industrial sectors and even the Software Engineering community. We would like to encourage the Software Engineering community to use this kind of systems as another tool in the toolbox, which complements or enhances other approaches like, for example, standards and checklists

  20. Considerations for implementing an organizational lessons learned process.

    Fosshage, Erik D

    2013-05-01

    This report examines the lessons learned process by a review of the literature in a variety of disciplines, and is intended as a guidepost for organizations that are considering the implementation of their own closed-loop learning process. Lessons learned definitions are provided within the broader context of knowledge management and the framework of a learning organization. Shortcomings of existing practices are summarized in an attempt to identify common pitfalls that can be avoided by organizations with fledgling experiences of their own. Lessons learned are then examined through a dual construct of both process and mechanism, with emphasis on integrating into organizational processes and promoting lesson reuse through data attributes that contribute toward changed behaviors. The report concludes with recommended steps for follow-on efforts.

    Mote, P. W.; Miles, E. L.; Whitely Binder, L.

    2008-12-01

    Since its founding in 1995, the Climate Impacts Group (CIG) at the University of Washington (UW) has achieved remarkable success at translating global- and regional-scale science into forms and products that are useful to, and used by, decision-makers. From GCM scenarios to research on the connection between global climate patterns and locally important factors like floods and wildfires, CIG's strong physical science foundation is matched by a vigorous and successful outreach program. As a result, CIG and its partner the Office of Washington State Climatologist at UW have made substantial progress at bridging the gap between climate science and decision-making, and are deeply involved in advising all levels of government and many business interests on adapting to climate variability and change. This talk will showcase some of the specific activities and tools, describe lessons learned, and illustrate how such efforts fit into a "National Climate Service."

  14. The lessons of SARS in Hong Kong.

    Lai, Thomas Sik To; Yu, Wai Cho

    2010-02-01

    Severe acute respiratory syndrome (SARS) is a novel coronavirus infection which broke out in Hong Kong in March 2003. Princess Margaret Hospital was designated to manage this new, mysterious and serious disease. Healthcare workers had to work under extremely stressful and often risky conditions to care for patients. Despite manpower and equipment reinforcements, staff infection occurred as a result of bodily exhaustion, working in an unfamiliar environment and lapses in infection control. Patients suffered even more, not only due to physical discomfort, but also because of the fear of isolation and death away from family and friends. Health authorities learnt their lessons in the outbreak and formulated emergency plans for future infectious disease epidemics. The healthcare infrastructure has been examined and upgraded with regard to intensive care capacity, infection control measures, professional training, manpower deployment, staff facilities, and stockpiling of drugs and personal protective equipment.

  15. Microplastics: addressing ecological risk through lessons learned.

    Syberg, Kristian; Khan, Farhan R; Selck, Henriette; Palmqvist, Annemette; Banta, Gary T; Daley, Jennifer; Sano, Larissa; Duhaime, Melissa B

    2015-05-01

    Plastic litter is an environmental problem of great concern. Despite the magnitude of the plastic pollution in our water bodies, only limited scientific understanding is available about the risk to the environment, particularly for microplastics. The apparent magnitude of the problem calls for quickly developing sound scientific guidance on the ecological risks of microplastics. The authors suggest that future research into microplastics risks should be guided by lessons learned from the more advanced and better understood areas of (eco) toxicology of engineered nanoparticles and mixture toxicity. Relevant examples of advances in these two fields are provided to help accelerate the scientific learning curve within the relatively unexplored area of microplastics risk assessment. Finally, the authors advocate an expansion of the "vector effect" hypothesis with regard to microplastics risk to help focus research of microplastics environmental risk at different levels of biological and environmental organization. © 2015 SETAC.

  16. Important lessons to be learnt from 'Daimler'

  17. Digital control for nuclear reactors - lessons learned

    Bernard, J.A.; Aviles, B.N.; Lanning, D.D.

    1992-01-01

    Lessons learned during the course of the now decade-old MIT program on the digital control of nuclear reactors are enumerated. Relative to controller structure, these include the importance of a separate safety system, the need for signal validation, the role of supervisory algorithms, the significance of command validation, and the relevance of automated reasoning. Relative to controller implementation, these include the value of nodal methods to the creation of real-time reactor physics and thermal hydraulic models, the advantages to be gained from the use of real-time system models, and the importance of a multi-tiered structure to the simultaneous achievement of supervisory, global, and local control. Block diagrams are presented of proposed controllers and selected experimental and simulation-study results are shown. In addition, a history is given of the MIT program on reactor digital control

  18. Lessons learnt from WLCG service deployment

    Shiers, J D

    2008-01-01

    This paper summarises the main lessons learnt from deploying WLCG production services, with a focus on Reliability, Scalability, Accountability, which lead to both manageability and usability. Each topic is analysed in turn. Techniques for zero-user-visible downtime for the main service interventions are described, together with pathological cases that need special treatment. The requirements in terms of scalability are analysed, calling for as much robustness and automation in the service as possible. The different aspects of accountability - which covers measuring/tracking/logging/monitoring what is going on - and has gone on - is examined, with the goal of attaining a manageable service. Finally, a simple analogy is drawn with the Web in terms of usability - what do we need to achieve to cross the chasm from small-scale adoption to ubiquity?

  19. Lessons learned using Snodgrass hypospadias repair.

    O'Connor, K M

    2012-02-03

    BACKGROUND: This is a review of our experience with the Snodgrass technique for distal hypospadias repair and we point to lessons learned in improving results. METHODS: We reviewed all patients who underwent Snodgrass hypospadias repair for distal hypospadias over a four-year period by a single surgeon. Chart review followed by parental telephone interview was used to determine voiding function, cosmesis and complication rate. RESULTS: Thirty children and three adults were identified. Age at surgery ranged from seven months to 39 years. The urinary stream was straight in 94%, and 97% reported a good or satisfactory final cosmetic outcome. One patient (3.3%) developed a urethral fistula and 21% developed meatal stenosis which required general anaesthetic. CONCLUSION: The Snodgrass urethroplasty provides satisfactory cosmetic and functional results. High rates of meatal stenosis initially encountered have improved with modifications to technique which include modified meatoplasty and routine meatal dilatation by the parents.

  20. Lessons learned in wake of WPPSS

    Koenen, A.V.; Gillespie, J.W.

    1984-01-01

    Several fundamentals of public power financial management have become more critical in the wake of the Washington Public Power Supply System (WPPSS) default: the human and financial costs of trying to resolve problems of this complexity after they occur will require an almost unimaginable amount of time and money that could be productively employed elsewhere; the economic feasibility of the project is paramount, and is far more important than its legal security or its attractiveness to utility managers; the ratepayers' ability and willingness to pay is the key security in public power financing; management performance, not promises, will be the measure of the post WPPSS marketplace; financial flexibility is crucial. Using these lessons, the author outlines a five-step program of strategic planning for planning and managing long-term projects

  1. Lessons learned during Type A Packaging testing

    O'Brien, J.H.; Kelly, D.L.

    1995-11-01

    For the past 6 years, the US Department of Energy (DOE) Office of Facility Safety Analysis (EH-32) has contracted Westinghouse Hanford Company (WHC) to conduct compliance testing on DOE Type A packagings. The packagings are tested for compliance with the U.S. Department of Transportation (DOT) Specification 7A, general packaging, Type A requirements. The DOE has shared the Type A packaging information throughout the nuclear materials transportation community. During testing, there have been recurring areas of packaging design that resulted in testing delays and/or initial failure. The lessons learned during the testing are considered a valuable resource. DOE requested that WHC share this resource. By sharing what is and can be encountered during packaging testing, individuals will hopefully avoid past mistakes

  2. Vacuum performances and lessons for 2012

    Baglin, V.; Bregliozzi, G.; Jimenez, J.M.; Lanza, G.

    2012-01-01

    During the LHC run 2011, a tremendous progress has been made towards the machine operation with design parameters. In the same time, the run confirmed the sensitivity of the beam vacuum system to the machine parameters. As expected, a successful scrubbing period allowed mitigating the effects of the electron cloud giving room to an entire filling of the ring with 50 ns beams. In parallel issues such as the impact of the beam screen regulation, pressures spikes and local outgassing were observed during the year. On-line mitigations and immediate compensatory measures implemented during the winter technical stop are reviewed together with their efficiencies. All unexpected pressure behaviours observed during 2011 are understood. The expected limitations while waiting for LS1 consolidation or when running with 25 ns beams are addressed. Lessons for 2012 are discussed. (authors)

  3. Sellafield Decommissioning Programme - Update and Lessons Learned

    Lutwyche, P. R.; Challinor, S. F.

    2003-01-01

    The Sellafield site in North West England has over 240 active facilities covering the full nuclear cycle from fuel manufacture through generation, reprocessing and waste treatment. The Sellafield decommissioning programme was formally initiated in the mid 1980s though several plants had been decommissioned prior to this primarily to create space for other plants. Since the initiation of the programme 7 plants have been completely decommissioned, significant progress has been made in a further 16 and a total of 56 major project phases have been completed. This programme update will explain the decommissioning arrangements and strategies and illustrate the progress made on a number of the plants including the Windscale Pile Chimneys, the first reprocessing plan and plutonium plants. These present a range of different challenges and requiring approaches from fully hands on to fully remote. Some of the key lessons learned will be highlighted

  4. Lessons taught by the Chernobyl accident

    Anon.

    2002-01-01

    On nuclear development, it is natural that safety is the most important condition. However, when occurring an accident in spite of earnest efforts on safety pursuit, it is essential for a technical developer to absorb some lessons from its contents as much as possible and show an attitude to use thereafter. The Chernobyl accident brought extraordinarily large damage in the history of nuclear technology development. Therefore, the edition group of the Japan Society of Atomic Energy introduced opinions of three groups of the Society (that is, groups on reactor physics, nuclear power generation, and human-machine system research) with some description on cause analysis of the accident and its result and effect. And, here was also shown four basic difference on design between RMBK type reactor in Chernobyl and LWR type reactor supplied in Japan. (G.K.)

  5. Lessons from the history of medicine.

    Waller, John

    2008-01-01

    What is the point of teaching the history of medicine? Many historians and clinicians find it regrettable that some medical students today will graduate knowing almost nothing of such "greats" of the past as Hippocrates, Galen, Vesalius, Harvey, Lister, and Pasteur. But does this really matter? After all, traditional history of medicine curricula tended to distort medicine's past, omitting the countless errors, wrong turns, fads, blunders, and abuses, in order to tell the sanitized stories of a few scientific superheroes. Modern scholarship has seriously challenged most of these heroic dramas; few of our heroes were as farsighted, noble, or obviously correct as once thought. Joseph Lister, for example, turns out to have had filthy wards, whereas William Harvey was devoted to the Aristotelianism he was long said to have overthrown [1]. But as the history of medicine has become less romanticized, it has also become much more relevant, for it promises to impart useful lessons in the vital importance of scientific scepticism.

  6. Lessons learned from the 1994 Northridge Earthquake

    Eli, M.W.; Sommer, S.C.

    1995-01-01

    Southern California has a history of major earthquakes and also has one of the largest metropolitan areas in the United States. The 1994 Northridge Earthquake challenged the industrial facilities and lifetime infrastructure in the northern Los Angeles (LA) area. Lawrence Livermore National Laboratory (LLNL) sent a team of engineers to conduct an earthquake damage investigation in the Northridge area, on a project funded jointly by the United States Nuclear Regulatory Commission (USNRC) and the United States Department of Energy (USDOE). Many of the structures, systems, and components (SSCs) and lifelines that suffered damage are similar to those found in nuclear power plants and in USDOE facilities. Lessons learned from these experiences can have some applicability at commercial nuclear power plants

  7. XML technology planning database : lessons learned

    Some, Raphael R.; Neff, Jon M.

    2005-01-01

    A hierarchical Extensible Markup Language(XML) database called XCALIBR (XML Analysis LIBRary) has been developed by Millennium Program to assist in technology investment (ROI) analysis and technology Language Capability the New return on portfolio optimization. The database contains mission requirements and technology capabilities, which are related by use of an XML dictionary. The XML dictionary codifies a standardized taxonomy for space missions, systems, subsystems and technologies. In addition to being used for ROI analysis, the database is being examined for use in project planning, tracking and documentation. During the past year, the database has moved from development into alpha testing. This paper describes the lessons learned during construction and testing of the prototype database and the motivation for moving from an XML taxonomy to a standard XML-based ontology.

  8. LESSONS LEARNED IN TESTING OF SAFEGUARDS EQUIPMENT

    Pepper, S.; Farnitano, M.; Carelli, J.; Hazeltine, J.; Bailey, D.

    2001-01-01

    The International Atomic Energy Agency's (IAEA) Department of Safeguards uses complex instrumentation for the application of safeguards at nuclear facilities around the world. Often, this equipment is developed through cooperation with member state support programs because the Agency's requirements are unique and are not met by commercially available equipment. Before approving an instrument or system for routine inspection use, the IAEA subjects it to a series of tests designed to evaluate its reliability. In 2000, the IAEA began to observe operational failures in digital surveillance systems. In response to the observed failures, the IAEA worked with the equipment designer and manufacturer to determine the cause of failure. An action plan was developed to correct the performance issues and further test the systems to make sure that additional operational issues would not surface later. This paper addresses the steps taken to address operation issues related to digital image surveillance systems and the lessons learned during this process

  9. Keynote on lessons from major radiation accidents

    Ortiz, P.; Oresegun, M.; Wheatley, J.

    2000-01-01

    Generic lessons have been learned from a relatively large number of accidents in the most relevant practices (a set of analysis have been made on about 90 radiotherapy events, 43 industrial radiography and nine from industrial irradiations); more specific lessons have been drawn from in-depth investigations of individual accidents. The body of knowledge is grouped as follows: a) radiotherapy is very unique in that humans (patients) are purposely given very high radiation doses (20-75 Gy) by placing them in the radiation beam or by placing radioactive sources in contact with tissues. Intended deterministic effects are the essence of the normal radiotherapy practice and relatively small deviation from the intended doses, i.e,, slightly higher or lower than intended may cause increased rate of severe complication or reduce probability of cure. Consequences of major accidents have been devastating, affecting tens, even hundreds of patients and causing death (directly or indirectly) to a large number of them; b) accidents involving industrial radiography are the most frequent cause of overexposure to workers (radiographers); c) accidents with industrial irradiators have lower probability of occurrence, however, they are deemed to be fatal, especially when whole body exposure to panoramic gamma irradiators occur; partial body irradiation from industrial or research accelerator beams has led to amputation of hands and legs; d) when control of sources was relinquished ('orphan' sources) this has resulted in severe injuries, in some cases death and widespread contamination of the environment. A tool for further dissemination of lessons will be an international reporting system of unusual radiation events (RADEV), being introduced world-wide. Accidents were rarely due to a single human error or isolated equipment failure. In most cases there was a combination of elements such as: a) unawareness of the potential for an accident, b) poor education, which usually did not

  10. Software Engineering Team Project - lessons learned

    Bogumiła Hnatkowska

    2013-06-01

    Full Text Available In the 2010/11 academic year the Institute of Informatics at Wroclaw University of Technology issued ’Software Engineering Team Project’ as a course being a part of the final exam to earn bachelor’s degree. The main assumption about the course was that it should simulate the real environment (a virtual IT company for its participants. The course was aimed to introduce issues regarding programming in the medium scale, project planning and management. It was a real challenge as the course was offered for more than 140 students. The number of staff members involved in its preparation and performance was more than 15. The paper presents the lessons learned from the first course edition as well as more detailed qualitative and quantitative course assessment.

  11. Abatement of CO2 emissions in the European Union

    Lesourne, J.; Keppler, J.H.; Jaureguy-Naudin, Maite; Smeers, Yves; Bouttes, Jean-Paul; Trochet, Jean-Michel; Dassa, Francois; Neuhoff, Karsten

    2008-01-01

    This first monograph of the Ifri program on European Governance and Geopolitics of Energy is devoted to the control of carbon dioxide emissions within the European Union. Since it is almost unanimously accepted that Greenhouse Gas emissions constitute the main cause of the observed increase of the world average temperature, the system implemented by the European Union to limit and decrease the CO 2 emissions is a significant pillar of the EU energy policy, the two others being the acceptance by the Member States of long-term commitments (for instance on the future share of renewable energy sources in their energy balance sheet) and the establishment of an internal market for electricity and gas. Though simple in principle, the European Union Greenhouse Gas Emission Trading Scheme (EU ETS) is in fact rather complex, and only experts really understand its merits and its deficiencies. These deficiencies are real and will have to be corrected in the future for the system to be effective. At this moment, when the 2005-2007 trial phase of the EU ETS is ending, the monograph has the purpose to stimulate the discussion between experts and to enable all those interested in the topic to understand the issues and to take part in the public debates on the subject. The monograph contains five papers: - 'An Overview of the CO 2 Emission Control System in the European Union' by Jacques Lesourne and Maite Jaureguy-Naudin. - 'Description and Assessment of EU CO 2 Regulations' by Yves Smeers. - 'Assessment of EU CO 2 Regulations' by Jean-Paul Bouttes, Jean-Michel Trochet and Francois Dassa. - 'Investment in Low Carbon Technologies, Policies for the Power Sector' by Karsten Neuhoff. - 'Lessons Learned from the 2005-2007 Trial Phase of the EU Emission Trading System' by Jan Horst Keppler

  12. SMART-1: Development and lessons learnt

    Rathsman, Peter; Kugelberg, Joakim; Bodin, Per; Racca, Giuseppe D.; Foing, Bernard; Stagnaro, Luca

    2005-07-01

    SMART-1 is the first of the small missions for advanced research and technology as part of ESA's science programme “Cosmic vision”. It was successfully launched on September 27, 2003 and is presently traveling towards its destination, the Moon. The main objective of the mission, to demonstrate solar electric primary propulsion for future Cornerstones (such as Bepi-Colombo), has already been achieved. At the time of writing the electric propulsion system has been working already for more than 3400 h and has provided a Delta-V to the spacecraft of more than 2500 m/s. The other technology objectives are also being fulfilled by the verification of the proper functioning of such on-board experiments like the X-Ka band transponder, the X-ray spectrometer, the near IR spectrometer, the laser link, etc. The scientific objectives are related to lunar science and will be fulfilled once the spacecraft enters its operational lunar orbit, currently expected for January 2005. SMART-1 lunar science investigations will include studies of the chemical composition of the Moon, of geophysical processes, environment and high-resolution studies in preparation for future steps of lunar exploration. SMART-1 has been an innovative mission in many aspects and we are now drawing some preliminary conclusions about the lessons to be learnt. The paper describes the spacecraft and the technology elements with particular emphasis to the technology nature of the mission. The on-board avionics employs many novel designs for spacecraft, including a serial CAN bus for data communication, autonomous star trackers and extensive use of auto-code generation for implementing the attitude control system and the failure, detection, isolation and recovery (FDIR). Finally, the orbital operation phase currently ongoing, including the routine electric propulsion operations and the instrument commissioning, is providing a wealth of data and lesson-learnt useful for future autonomous planetary missions.

  13. NAPAP: A lesson in science, policy

    Russell, M.

    1993-01-01

    Perplexing environmental questions, such as acid rain and global warming, cry out for policy solutions based upon solid scientific evidence. Scientists and politicians agree on this but have trouble finding an effective way to do it. Milton Russell of the University of Tennessee and Oak Ridge National Laboratory describes a major, but only partially successful, effort that he believes contains valuable lessons for scientists and policy makers in the future. It is the National Acid Precipitation Assessment Program (NAPAP), launched in 1980 to generate the latest scientific evidence to guide national debate on clean-air legislation. The program open-quotes created an unprecedented body of scientific research on an environmental issue of the first order,close quotes Russell says. Yet, he admits, its influence was virtually nil on the legislation that ultimately emerged on the subject. Russell blames this lack of influence on NAPAP's failure to provide adequate assessment of its research findings, its failure to communicate the results on a timely and effective basis, and on open-quotes political forces that sought legislation rather than a full explication of issues.close quotes Out of the experience, Russell finds lessons for the future: open-quotes First, if the scientific finding are to have an impact on policy, assessment must become a priority as important as scientific research. Second, for projects designed to help decision makers, scientific research must be considered a resource, not an end product. Third, timely, lucid communication must be an essential element of the project, not a marginal activity.close quotes NAPAP, Russell concludes, open-quotes proved a long-term scientific success and a short-term policy disappointment.close quotes Then he warns, open-quotes Future science programs ignore the NAPAP experience at their own risk.close quotes

  14. Leading in crisis: lessons for safety leaders.

    George, William W; Denham, Charles R; Burgess, L Hayley; Angood, Peter B; Keohane, Carol

    2010-03-01

    The National Quality Forum (NQF) Safe Practices are a group of 34 evidence-based Safe Practices that should be universally used to reduce the risk of harm to patients. Four of these practices specifically address leadership. A recently published book, 7 Lessons for Leading in Crisis, offers practical advice on how to lead in crisis. An analysis of how concepts from the 7 lessons could be applied to the Safe Practices was presented nationally by webinar to assess the audience's reaction to the information. The objective of this article was to present the information and the audience's reaction to it. Recommendations for direct actions that health care leaders can take to accelerate adoption of NQF Safe Practices were presented to health care leaders, followed by an immediate direct survey that used Reichheld's "Net Promoter Score" to assess whether the concepts presented were considered applicable and valuable to the audience. In a separate presentation, the challenges and crises facing nursing leaders were addressed by nursing leaders. Six hundred seventy-four hospitals, with an average of 4.5 participants per hospital, participated in the webinar. A total of 272 safety leaders responded to a survey immediately after the webinar. A Net Promoter Score assessment revealed that 58% of those surveyed rated the value of the information at 10, and 91% scored the value of the webinar to be between 8 and 10, where 10 is considered a strong recommendation that those voting would recommend this program to others. The overwhelmingly high score indicated that the principles presented were important and valuable to this national audience of health care leadership. The 2010 environment of uncertainty and shrinking financial resources poses significant risk to patients and new challenges for leaders at all levels. A values-grounded focus on personal accountability for leading in crisis situations strongly resonates with those interested in or leading patient safety initiatives.

  15. Lessons learned -- NREL Village Power Program

    Flowers, L.

    1998-07-01

    In 1993, a workshop was convened at the National Renewable Energy Laboratory (NREL) to discuss the issues of applying renewable energy in a sustainable manner to international rural development. One of the summary recommendations was that NREL could assist in the renewable energy for rural electrification effort by developing and supplying six related activities: resource assessment, comparative analysis and modeling, performance monitoring and analysis, pilot project development, internet-based project data, communications, and training. In response to this recommendation, NREL launched its Village Power Program consisting of these activities that cut across NREL technologies and disciplines. Currently NREL is active in 20 countries, with pilot projects in 12 of those countries. At this time the technologies include photovoltaics, wind, biomass, and hybrids. The rural applications include home lighting and communications, water pumping, schools and health posts, battery charging stations, ecotourism, and village systems. These pilot projects are central to the renewable energy village power development through the demonstration of three aspects critical to replication and implementation of the projects on a significant scale. The three aspects are technical functionality, economic competitiveness, and institutional sustainability. It is important to note that the pilot projects from which NREL's experience has been gained were funded and, in many cases, developed by other organizations and agencies. NREL's role has been one of technical assistance or project management or both. The purpose of this paper is to describe the lessons NREL staff has gleaned from their participation in the various pilot projects. The author hopes that these lessons will help the Renewable Energy-Based Rural Electrification (RERE) community in implementing sustainable projects that lead to replication.

    2016-01-01

    The Lessons Learned Process Improvement Team was tasked to gain an understanding of the existing lessons learned environment within the major programs at Sandia National Laboratories, identify opportunities for improvement in that environment as compared to desired attributes, propose alternative implementations to address existing inefficiencies, perform qualitative evaluations of alternative implementations, and recommend one or more near-term activities for prototyping and/or implementation. This report documents the work and findings of the team.

  1. Constellation Program: Lessons Learned. Volume 1; Executive Summary

    Rhatigan, Jennifer L. (Editor)

    2011-01-01

    This document (Volume I) provides an executive summary of the lessons learned from the Constellation Program. A companion Volume II provides more detailed analyses for those seeking further insight and information. In this volume, Section 1.0 introduces the approach in preparing and organizing the content to enable rapid assimilation of the lessons. Section 2.0 describes the contextual framework in which the Constellation Program was formulated and functioned that is necessary to understand most of the lessons. Context of a former program may seem irrelevant in the heady days of new program formulation. However, readers should take some time to understand the context. Many of the lessons would be different in a different context, so the reader should reflect on the similarities and differences in his or her current circumstances. Section 3.0 summarizes key findings developed from the significant lessons learned at the program level that appear in Section 4.0. Readers can use the key findings in Section 3.0 to peruse for particular topics, and will find more supporting detail and analyses in Section 4.0 in a topical format. Appendix A contains a white paper describing the Constellation Program formulation that may be of use to readers wanting more context or background information. The reader will no doubt recognize some very similar themes from previous lessons learned, blue-ribbon committee reviews, National Academy reviews, and advisory panel reviews for this and other large-scale human spaceflight programs; including Apollo, Space Shuttle, Shuttle/Mir, and the ISS. This could represent an inability to learn lessons from previous generations; however, it is more likely that similar challenges persist in the Agency structure and approach to program formulation, budget advocacy, and management. Perhaps the greatest value of these Constellation lessons learned can be found in viewing them in context with these previous efforts to guide and advise the Agency and its

  2. Economical benzene emission reduction

    Schuetz, R.

    1999-01-01

    Benzene has been classified as a toxic compound under the Canadian Environmental Protection Act. This has prompted the Alberta Energy and Utilities Board (AEUB) to introduce specific reporting and monitoring guidelines for the oil and gas industry regarding excessive benzene emissions. Glycol dehydration units have been determined to be the major single source of benzene emissions causing air and soil pollution. DualTank Corp. has designed a condensation and storage tank unit to enhance emission reduction, odour elimination and liquid recovery from dehydration units. Their newly designed combined tank unit consists of a large, uninsulated surface area for cooling, and an excessive internal volume for increased retention time. The first prototype was installed in December 1998 at an Enerplus Resources Site. The system provides excellent benzene emission reduction and the elimination of odours and visual plumes. Effective January 1, 1999, the petroleum and natural gas industry must either clean up excessive emissions voluntarily or face government imposed regulations, facility shutdowns and/or fines. 1 fig

  5. Practical acoustic emission testing

    2016-01-01

    This book is intended for non-destructive testing (NDT) technicians who want to learn practical acoustic emission testing based on level 1 of ISO 9712 (Non-destructive testing – Qualification and certification of personnel) criteria. The essential aspects of ISO/DIS 18436-6 (Condition monitoring and diagnostics of machines – Requirements for training and certification of personnel, Part 6: Acoustic Emission) are explained, and readers can deepen their understanding with the help of practice exercises. This work presents the guiding principles of acoustic emission measurement, signal processing, algorithms for source location, measurement devices, applicability of testing methods, and measurement cases to support not only researchers in this field but also and especially NDT technicians.

  6. Instantaneous wave emission model

    Kruer, W.L.

    1970-12-01

    A useful treatment of electrostatic wave emission by fast particles in a plasma is given. First, the potential due to a fast particle is expressed as a simple integration over the particle orbit; several interesting results readily follow. The potential in the wake of an accelerating particle is shown to be essentially that produced through local excitation of the plasma by the particle free-streaming about its instantaneous orbit. Application is made to one dimension, and it is shown that the wave emission and adsorption synchronize to the instantaneous velocity distribution function. Guided by these calculations, we then formulate a test particle model for computing the instantaneous wave emission by fast particles in a Vlasov plasma. This model lends itself to physical interpretation and provides a direct approach to many problems. By adopting a Fokker-Planck description for the particle dynamics, we calculate the broadening of the wave-particle resonance due to velocity diffusion and drag

    1999-01-01

    The tomography by positrons emission is a technology that allows to measure the concentration of positrons emission in a tri dimensional body through external measurements. Among the isotope emissions have carbon isotopes are ( 11 C), of the oxygen ( 15 O), of the nitrogen ( 13 N) that are three the element that constitute the base of the organic chemistry. Theses have on of the PET's most important advantages, since many biological interesting organic molecules can be tracer with these isotopes for the metabolism studies 'in vivo' through PET, without using organic tracers that modify the metabolism. The mentioned isotopes, also possess the characteristic of having short lifetime, that constitute on of PET's advantages from the dosimetric point of view. Among 11 C, 15 O, and 13 N, other isotopes that can be obtained of a generator as the 68 Ga and 82 Rb

  8. Carbon emissions control strategies

    Chandler, W.U.

    1990-01-01

    This study was undertaken to address a fundamental issue: the cost of slowing climate change. Experts in eight nations were asked to evaluate, using the best economic models available, the prospects for reducing fossil fuel-based carbon emissions in their respective nations. The nations selected as case studies include: the Soviet Union, Poland, the United States, Japan, Hungary, France, the United Kingdom, and Canada. As important contributors to the greenhouse effect, these industrialized nations must find ways to substantially reduce their emissions. This is especially critical given that developing nations' emissions are expected to rise in the coming decades in the search for economic development. Ten papers have been processed separately for inclusion in the appropriate data bases

  10. Groups of bats improve sonar efficiency through mutual suppression of pulse emissions.

    Jenna eJarvis

    2013-06-01

    Full Text Available How bats adapt their sonar behavior to accommodate the noisiness of a crowded day roost is a mystery. Some bats change their pulse acoustics to enhance the distinction between theirs and another bat’s echoes, but additional mechanisms are needed to explain the bat sonar system’s exceptional resilience to jamming by conspecifics. Variable pulse repetition rate strategies offer one potential solution to this dynamic problem, but precisely how changes in pulse rate could improve sonar performance in social settings is unclear. Here we show that bats decrease their emission rates as population density increases, following a pattern that reflects a cumulative mutual suppression of each other’s pulse emissions. Playback of artificially-generated echolocation pulses similarly slowed emission rates, demonstrating that suppression was mediated by hearing the pulses of other bats. Slower emission rates did not support an antiphonal emission strategy but did reduce the relative proportion of emitted pulses that overlapped with another bat’s emissions, reducing the relative rate of mutual interference. The prevalence of acoustic interferences occurring amongst bats was empirically determined to be a linear function of population density and mean emission rates. Consequently as group size increased, small reductions in emission rates spread across the group partially mitigated the increase in interference rate. Drawing on lessons learned from communications networking theory we show how modest decreases in pulse emission rates can significantly increase the net information throughput of the shared acoustic space, thereby improving sonar efficiency for all individuals in a group. We propose that an automated acoustic suppression of pulse emissions triggered by bats hearing each other's emissions dynamically optimizes sonar efficiency for the entire group.

    This book is dedicated to field emission electronics, a promising field at the interface between “classic” vacuum electronics and nanotechnology. In addition to theoretical models, it includes detailed descriptions of experimental and research techniques and production technologies for different types of field emitters based on various construction principles. It particularly focuses on research into and production of field cathodes and electron guns using recently developed nanomaterials and carbon nanotubes. Further, it discusses the applications of field emission cathodes in new technologies such as light sources, flat screens, microwave and X-ray devices.

  12. Positron emission tomography

    Wienhard, K.; Heiss, W.D.

    1984-01-01

    The principles and selected clinical applications of positron emission tomography are described. In this technique a chemical compound is labeled with a positron emitting isotope and its biochemical pathway is traced by coincidence detection of the two annihilation photons. The application of the techniques of computed tomography allows to reconstruct the spatial distribution of the radioactivity within a subject. The 18 F-deoxyglucose method for quantitative measurement of local glucose metabolism is discussed in order to illustrate the possibilities of positron emission tomography to record physiological processes in vivo.

    1981-01-01

    Positron emitting radiopharmaceuticals have special applications in in-vivo studies of biochemical processes. The combination of a cyclotron for the production of radionuclides and a positron emission tomograph for the registration of the distribution of radioactivity in the body enables the measurement of local radioactivity concentration in tissues, and opens up new possibilities in the diagnosis and examination of abnormalities in the metabolism. The principles and procedures of positron emission tomography are described and the necessary apparatus considered, with emphasis on the positron camera. The first clinical applications using 55 Co bloemycine for tumor detection are presented. (C.F.)

    Krohn, V.E.

    1976-01-01

    The Saha-Langmuir equation that describes the equilibrium emission process, surface ionization, has also been used to describe ion yields observed in the non-equilibrium emission process, sputtering. In describing sputtering, it is probably best to include the potential due to an image charge in the expression for negative as well as positive ion yield and to treat the work function and the temperature as parameters having limited physical significance. Arguments are presented to suggest that sputtered material is not emitted from a plasma. (Auth.)

  15. A Cancun stake: to revitalize climate cooperation while improving transparency about national greenhouse gas emissions

    2010-12-01

    After having recalled the instruments which are available for the UNFCCC (United Nations Framework Convention on Climate Change) to ensure an as much as transparent as possible information transmission between states about greenhouse gas emissions, this article questions the way the Copenhagen agreement can be implemented while considering the discussions which took place. It draws lessons from other previous examples of international cooperation: WTO agreements, the Clean Development Mechanism. Three propositions are made in the perspective of the Cancun conference: to create a reliable world inventory of emissions, to organize cooperation with countries wishing to define statistics for their emission monitoring, and to reinforce transparency and control of measures (with the MRV criteria) which are subsidized by the international community

  16. Connecting polar research to NGSS STEM classroom lessons

    Brinker, R.; Kast, D.

    2016-12-01

    Next Generation Science Standards (NGSS) are designed to bring consistent, rigorous science teaching across the United States. Topics are categorized as Performance Expectations (PE), Disciplinary Core Ideas (DCI), Cross-Cutting Concepts (CCC), and Science and Engineering Practices (SEP). NGSS includes a focus on environmental science and climate change across grade levels. Earth and planetary sciences are required at the high school level. Integrating polar science lessons into NGSS classrooms brings relevant, rigorous climate change curriculum across grade levels. Polar science provides opportunities for students to use current data during lessons, conduct their own field work, and collaborate with scientists. Polar science provides a framework of learning that is novel to most students. Inquiry and engagement are high with polar science lessons. Phenomenon related to polar science provide an excellent tool for science teachers to use to engage students in a lesson, stimulate inquiry, and promote critical thinking. When taught effectively, students see the connections between their community, polar regions and climate change, regardless of where on the planet students live. This presentation describes examples of how to effectively implement NGSS lessons by incorporating polar science lessons and field research. Examples of introductory phenomenon and aligned PEs, CCCs, DCIs, and SEPs are given. Suggested student activities, assessments, examples of student work, student research, labs, and PolarTREC fieldwork, use of current science data, and connections to scientists in the field are provided. The goals of the presentation are to give teachers a blueprint to follow when implementing NGSS lessons, and give scientists an understanding of the basics of NGSS so they may be better able to relate their work to U.S. science education and be more effective communicators of their science findings.

  18. Serbian SNF Repatriation Operation. Issues, Solving, Lesson

    Smirnov, A. [Research and Development Company ' Sosny' , Moscow (Russian Federation)

    2011-07-01

    For now the removal of SNF from RA reactor site (PC NFS, Serbia) is the most time-consuming and technically complicated operation under RRRFR Program. The most efficient techniques and lessons learned from other projects of the RRRFR Program as well as new unique technical decisions were used. Two big challenges were resolved during implementation of Serbian Project: (1) preparation of damaged fuel located in the packages unsuitable for transport, taking into account insufficient infrastructure of RA reactor site and (2) removal of large amount of fuel in one multimodal shipment through several transit countries. The main attention was paid to safety justification of all activities. All approvals were obtained in Russia, Serbia and transit countries. Special canisters were designed for transportation of specific RA reactor fuel (of small dimensions, unidentifiable, damaged due to corrosion). The canister design was selected to be untight - it was the most expedient decision for that case from safety perspective. The technology and a set of equipment were designed for remote removal of the fuel from the existing package (aluminum barrels and reactor channels) and placing of the fuel into the new canisters. After fabrication and assembling of the equipment theoretical and practical training of the personnel was performed. Fuel repackaging took about 5 months. SNF was transported in TUK-19 and SKODA VPVR/M casks. The baskets of large capacity were designed and fabricated for SKODA VPVR/M casks. Special requirements to drying the packages and composition of gaseous medium inside were justified to ensure fire and explosion safety. Specialized ISO-containers and transfer equipment designed under Romanian Project were used together with TUK-19 casks. A forklift and mobile rail system were used to handle SKODA VPVR/M casks under conditions of low capacity of the cranes at the facility. Due to the tight schedule of RRRFR Program as well as geographical peculiarities of RA

  19. Existing facilities and past practices: Lessons learned

    Huizenga, D.; Tonkay, D.W.; Owens, K.

    2000-01-01

    Article 12 of the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management (Joint Convention) requires parties to the Joint Convention to review the safety of existing radioactive waste management facilities 'to ensure that, if necessary, all reasonably practicable improvements are made to upgrade the safety of such a facility'. Also required is a review of the results of past practices to determine 'whether any intervention is needed for reasons of radiation protection' and to consider whether the benefits of the intervention or remediation are sufficient, with regard to the costs and the impact on workers, the public and the environment. This paper discusses the experience of the United States Department of Energy in terms of the lessons learned from operating radioactive waste management facilities and from undertaking intervention or remedial action, and from decision making in an international context. Overarching safety principles are discussed, including integrating safety into all work practices and minimizing the generation of waste. Safety review lessons learned with existing facilities are discussed with respect to: applying new requirements to old facilities, taking a life-cycle perspective of waste management, improving high level waste facility management, and blending current and past practices with respect to the process used to arrive at decisions for intervention. Special emphasis is placed on the need to provide for early and substantive input from the involved regulatory agencies, Native American tribes, and those citizens and groups with an interest in the decisions. Examples of intervention decisions are discussed, including examples taken from uranium mill tailings operations, from cleanup of a former uranium processing plant site, from evaluation of pre-1970 buried 'transuranic waste' sites, and from decommissioning or closure of high level waste storage tanks. The paper concludes that on the

  20. Calibration Lessons Learned from Hyperion Experience

    Casement, S.; Ho, K.; Sandor-Leahy, S.; Biggar, S.; Czapla-Myers, J.; McCorkel, J.; Thome, K.

    2009-12-01

    The use of hyperspectral imagers to provide climate-quality data sets, such as those expected from the solar reflective sensor on the Climate Absolute Radiance and Refractivity Observatory (CLARREO), requires stringent radiometric calibration requirements. These stringent requirements have been nearly met with broadband radiometers such as CERES, but high resolution spectrometers pose additional challenges. A review of the calibration processes for past space-based HSIs provide guidance on the calibration processes that will be needed for future sensors. In November 2000, the Earth Observer-1 (EO-1) platform was launched onboard a Boeing Delta II launch vehicle. The primary purpose of the EO-1 mission was to provide a technological testbed for spaceborne components. The platform has three sensors onboard, of which, the hyperspectral imager (HSI) Hyperion, is discussed here. The Hyperion sensor at the time had no comparable sensor in earth orbit, being the first grating-based, hyperspectral, civilian sensor in earth orbit. Ground and on-orbit calibration procedures including all cross-calibration activities have achieved an estimated instrument absolute radiometric error of 2.9% in the Visible channel (0.4 - 1.0 microns) and 3.4% in the shortwave infrared (SWIR, 0.9 - 2.5 microns) channel (EO-1/Hyperion Early Orbit Checkout Report Part II On-Orbit Performance Verification and Calibration). This paper describes the key components of the Hyperion calibration process that are applicable to future HSI missions. The pre-launch methods relied on then newly-developed, detector-based methods. Subsequent vicarious methods including cross-calibration with other sensors and the reflectance-based method showed significant differences from the prelaunch calibration. Such a difference demonstrated the importance of the vicarious methods as well as pointing to areas for improvement in the prelaunch methods. We also identify areas where lessons learned from Hyperion regarding

  2. Emissions - problems and benefits

    Rossi, C.; Hurd, P.J.

    1992-01-01

    Air pollution due to emissions arising from the use of biomass in electricity generation is discussed. One of the most attractive aspects of the use of biomass is that there is no net increase of carbon dioxide in the atmosphere. During growth biomass absorbs CO 2 ; during combustion, either directly or as biomass derived fuels, it releases CO 2 , making a closed cycle. Another benefit from the use of biomass is its typically very low sulphur content and the consequent low sulphur oxide emissions from biomass-fired generation plants. Biomass is, however, less satisfactory in relation to nitrogen oxides (NO x ). Control of the nitrogen content of the biomass feedstock, advanced high technology combustion techniques and some post-engine treatment may all be necessary to comply with the legal limits for NO x emissions. The low ash content of biomass, particularly biomass derived oils, makes it possible to limit particulate emission to very low levels. It will be important, though, to bear in mind the need to limit the sodium and potassium content to below 1 ppm by mass in bio-oil to be used in a high temperature gas turbine. Levels of micropollutants will be low if the chlorine content of biomass feedstock is low. However, residence times at peak temperature in typical gas turbines combustors are too short to destroy some micropollutants. (UK)

  6. Quantifying Anthropogenic Dust Emissions

    Webb, Nicholas P.; Pierre, Caroline

    2018-02-01

    Anthropogenic land use and land cover change, including local environmental disturbances, moderate rates of wind-driven soil erosion and dust emission. These human-dust cycle interactions impact ecosystems and agricultural production, air quality, human health, biogeochemical cycles, and climate. While the impacts of land use activities and land management on aeolian processes can be profound, the interactions are often complex and assessments of anthropogenic dust loads at all scales remain highly uncertain. Here, we critically review the drivers of anthropogenic dust emission and current evaluation approaches. We then identify and describe opportunities to: (1) develop new conceptual frameworks and interdisciplinary approaches that draw on ecological state-and-transition models to improve the accuracy and relevance of assessments of anthropogenic dust emissions; (2) improve model fidelity and capacity for change detection to quantify anthropogenic impacts on aeolian processes; and (3) enhance field research and monitoring networks to support dust model applications to evaluate the impacts of disturbance processes on local to global-scale wind erosion and dust emissions.

  13. Refining MARGINS Mini-Lessons Using Classroom Observations

    Iverson, E. A.; Manduca, C. A.; McDaris, J. R.; Lee, S.

    2009-12-01

    One of the challenges that we face in developing teaching materials or activities from research findings is testing the materials to determine that they work as intended. Traditionally faculty develop material for their own class, notice what worked and didn’t, and improve them the next year. However, as we move to a community process of creating and sharing teaching materials, a community-based process for testing materials is appropriate. The MARGINS project has piloted such a process for testing teaching materials and activities developed as part of its mini-lesson project (http://serc.carleton.edu/margins/index.html). Building on prior work developing mechanisms for community review of teaching resources (e.g. Kastens, 2002; Hancock and Manduca, 2005; Mayhew and Hall, 2007), the MARGINS evaluation team developed a structured classroom observation protocol. The goals of field testing are to a) gather structured, consistent feedback for the lesson authors based on classroom use; b) guide reviewers of these lessons to reflect on research-based educational practice as a framework for their comments; c) collect information on the data and observations that the reviewer used to underpin their review; d) determine which mini-lessons are ready to be made widely available on the website. The protocol guides faculty observations on why they used the activity, the effectiveness of the activity in their classroom, the success of the activity in leading to the desired learning, and what other faculty need to successfully use the activity. Available online (http://serc.carleton.edu/margins/protocol.html), the protocol can be downloaded and completed during instruction with the activity. In order to encourage review of mini-lessons using the protocol, a workshop focused on review and revision of activities was held in May 2009. In preparation for the workshop, 13 of the 28 participants chose to field test a mini-lesson prior to the workshop and reported that they found this

  14. Chinese haze versus Western smog: lessons learned.

    Zhang, Junfeng Jim; Samet, Jonathan M

    2015-01-01

    Air pollution in many Chinese cities has been so severe in recent years that a special terminology, the "Chinese haze", was created to describe China's air quality problem. Historically, the problem of Chinese haze has developed several decades after Western high-income countries have significantly improved their air quality from the smog-laden days in the early- and mid-20(th) century. Hence it is important to provide a global and historical perspective to help China combat the current air pollution problems. In this regard, this article addresses the followings specific questions: (I) What is the Chinese haze in comparison with the sulfurous (London-type) smog and the photochemical (Los Angeles-type) smog? (II) How does Chinese haze fit into the current trend of global air pollution transition? (III) What are the major mitigation measures that have improved air quality in Western countries? and (IV) What specific recommendations for China can be derived from lessons and experiences from Western countries?

  15. The real leadership lessons of Steve Jobs.

    Isaacson, Walter

    2012-04-01

    The author, whose biography of Steve Jobs was an instant best seller after the Apple CEO's death in October 2011, sets out here to correct what he perceives as an undue fixation by many commentators on the rough edges of Jobs's personality. That personality was integral to his way of doing business, Isaacson writes, but the real lessons from Steve Jobs come from what he actually accomplished. He built the world's most valuable company, and along the way he helped to transform a number of industries: personal computing, animated movies, music, phones, tablet computing, retail stores, and digital publishing. In this essay Isaacson describes the 14 imperatives behind Jobs's approach: focus; simplify; take responsibility end to end; when behind, leapfrog; put products before profits; don't be a slave to focus groups; bend reality; impute; push for perfection; know both the big picture and the details; tolerate only "A" players; engage face-to-face; combine the humanities with the sciences; and "stay hungry, stay foolish."

  16. Lessons Learned in Risk Management on NCSX

    Neilson, G.H.; Gruber, C.O.; Harris, Jeffrey H.; Rej, D.J.; Simmons, R.T.; Strykowsky, R.L.

    2010-01-01

    The National Compact Stellarator Experiment (NCSX) was designed to test physics principles of an innovative stellarator design developed by Princeton Plasma Physics Laboratory and Oak Ridge National Laboratory. Construction of some of the major components and subassemblies was completed, but the estimated cost and schedule for completing the project grew as the technical requirements and risks became better understood, leading to its cancellation in 2008. The project's risks stemmed from its technical challenges, primarily the complex component geometries and tight tolerances that were required. The initial baseline, which was established in 2004, was supported by a risk management plan and risk-based contingencies, both of which proved to be inadequate. Technical successes were achieved in the construction of challenging components and subassemblies, but cost and schedule growth was experienced. As part of an effort to improve project performance, a new risk management program was devised and implemented in 2007-2008. It led to a better understanding of project risks, a sounder basis for contingency estimates, and improved management tools. Although the risks were ultimately unacceptable to the sponsor, valuable lessons in risk management were learned through the experiences with the NCSX project.

  17. Media advocacy: lessons from community experiences.

    Jernigan, D H; Wright, P A

    1996-01-01

    Media advocacy is the strategic use of mass media and community organizing as a resource for advancing a social or public policy initiative. Across the United States, communities are using media advocacy to promote healthier public policies and environments. The U.S. Center for Substance Abuse Prevention commissioned numerous case studies of media advocacy on alcohol and tobacco issues in a diverse array of communities, including efforts in African-American and Latino communities or using computer-based electronic communication systems. The paper describes these efforts briefly, and summarizes lessons learned, including: media advocacy can lead to larger victories when used as a complement to community organizing in the context of a larger strategic vision for policy change; like policy advocacy, media advocacy is best done in the context of clear long-term goals; conscious framing, guiding the choice of spokespeople, visuals, and messages, can alter media coverage and public debate of health policies; advocates need to respect the media but also remember that they have power in relation to the media; and media advocacy is often controversial and not suited to every situation. The case studies show that media advocacy is a potent tool for public health workers, making an important contribution to campaigns to promote healthier public policies.

  18. Four lessons on Randstad-Holland

    Joan Moreno

    2014-10-01

    Full Text Available The Dutch delta, at the confluence of the courses of the Rhine, Meuse and Scheldt rivers, is the paradigmatic territory of networks from the earliest stages of the human settlement. In an unsteady landscape, made up of a mosaic of marshes, bogs and sand dunes; irrigated by a maze with rivers, streams and canals; transportation network is the element that strengthens and unites the urban structure for centuries. This article discusses the integration of the Dutch transport network and the urban network from four noted episodes in the history of mobility in the Netherlands: the Trekvaarten [towpaths], the Oude Lijn [Old railway line], the Halsketting [nodal corridor], and finally, the intermodal center Zuidas-Amsterdam. The aim of this article is to show how the development of the Dutch urban network is conditioned by structural changes in the transportation network, and how the evolution of the urban mobility system determines simultaneously both: regional and local spheres. Ultimately, four lessons in mobility and urbanity in the Randstad-Holland that take the case of study further and are a model in the development of an integrated metropolitan system.

    Hill, P.; Hille, R.

    1999-01-01

    This report presents results and lessons learned by one of the so far largest assessments of a post-accidental situation. Funded by the Federal Republic of Germany the German Chernobyl Project investigated in the years 1991-1993 the radiological situation in contaminated regions of the Russian Federation, Belarus and Ukraine. Measurements included a mass screening of the population in order to determine the Cesium body burdens of 250,000+ individuals in more than 240 settlements as well as the evaluation of external doses in selected settlements with soil contaminations varying from less than 74 kBq/m 2 to about 3700 kBq/m 2 including some, where decontamination measures had previously been taken. Also in many settlements environmental monitoring was undertaken. For most individuals doses did not exceed the international annual limits set for the general population. Open and comprehensive communication of results was favourably accepted by the public. In a few settlements the radiological situation has been followed up till to date. (author)

  20. Transradial access: lessons learned from cardiology.

    Snelling, Brian M; Sur, Samir; Shah, Sumedh Subodh; Marlow, Megan M; Cohen, Mauricio G; Peterson, Eric C

    2018-05-01

    Innovations in interventional cardiology historically predate those in neuro-intervention. As such, studying trends in interventional cardiology can be useful in exploring avenues to optimise neuro-interventional techniques. One such cardiology innovation has been the steady conversion of arterial puncture sites from transfemoral access (TFA) to transradial access (TRA), a paradigm shift supported by safety benefits for patients. While neuro-intervention has unique anatomical challenges, the access itself is identical. As such, examining the extensive cardiology literature on the radial approach has the potential to offer valuable lessons for the neuro-interventionalist audience who may be unfamiliar with this body of work. Therefore, we present here a report, particularly for neuro-interventionalists, regarding the best practices for TRA by reviewing the relevant cardiology literature. We focused our review on the data most relevant to our audience, namely that surrounding the access itself. By reviewing the cardiology literature on metrics such as safety profiles, cost and patient satisfaction differences between TFA and TRA, as well as examining the technical nuances of the procedure and post-procedural care, we hope to give physicians treating complex cerebrovascular disease a broader data-driven understanding of TRA. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  1. Marketing healthcare: lessons for smaller hospitals.

    Chowdhary, N R

    2000-02-01

    Recently, I have noted ubiquitous trends that lead me to conclude that we are on the brink of a fundamental change in the structure of healthcare delivery. Hospitals are changing. The hospital, that enduring and pervasive organization, which for decades has delivered the vast majority of acute care services is being re-conceptualized. Administrators and executives in today's hospitals are beginning to recognize the disaffection of constituents and the necessity to change from placing their own agenda or that of their profession over the needs of the customer. A lesson that is increasingly being heeded, particularly by the leading hospitals, is that a belief in one's own importance or a feeling of invulnerability represents an anachronistic stance. No hospital today can afford to retain a view that it is more important than the patients it serves, or that it is invulnerable. The external pressures are already clear--the actors, factors and forces in the external environment are forcing hospitals to re-evaluate efficiency, effectiveness and delivery arrangements. The rise to prominence of the outcomes movement is part of this trend. The present study was an attempt to assess the practices and trends in the modern smaller hospitals as a part of their strategy to match the competitive pressures.

  2. Lessons Learned in Risk Management on NCSX

    Neilson, G.H.; Gruber, C.O.; Harris, J.H.; Rej, D.J.; Simmons, R.T.; Strykowsky, R.L.

    2009-01-01

    The National Compact Stellarator Experiment (NCSX) was designed to test physics principles of an innovative stellarator design developed by the Princeton Plasma Physics Laboratory and Oak Ridge National Laboratory. Construction of some of the major components and sub-assemblies was completed, but the estimated cost and schedule for completing the project grew as the technical requirements and risks became better understood, leading to its cancellation in 2008. The project's risks stemmed from its technical challenges, primarily the complex component geometries and tight tolerances that were required. The initial baseline, established in 2004, was supported by a risk management plan and risk-based contingencies, both of which proved to be inadequate. Technical successes were achieved in the construction of challenging components and subassemblies, but cost and schedule growth was experienced. As part of an effort to improve project performance, a new risk management program was devised and implemented in 2007-08. It led to a better understanding of project risks, a sounder basis for contingency estimates, and improved management tools. Although the risks ultimately were unacceptable to the sponsor, valuable lessons in risk management were learned through the experiences with the NCSX project

  3. Value-Based Requirements Traceability: Lessons Learned

    Egyed, Alexander; Grünbacher, Paul; Heindl, Matthias; Biffl, Stefan

    Traceability from requirements to code is mandated by numerous software development standards. These standards, however, are not explicit about the appropriate level of quality of trace links. From a technical perspective, trace quality should meet the needs of the intended trace utilizations. Unfortunately, long-term trace utilizations are typically unknown at the time of trace acquisition which represents a dilemma for many companies. This chapter suggests ways to balance the cost and benefits of requirements traceability. We present data from three case studies demonstrating that trace acquisition requires broad coverage but can tolerate imprecision. With this trade-off our lessons learned suggest a traceability strategy that (1) provides trace links more quickly, (2) refines trace links according to user-defined value considerations, and (3) supports the later refinement of trace links in case the initial value consideration has changed over time. The scope of our work considers the entire life cycle of traceability instead of just the creation of trace links.

  4. Forest fires in 2017: a useful lesson

    2017-08-01

    Full Text Available Forest fires in 2017: a useful lesson. Forest fires, together with the decline of silviculture practice, are one of the most important natural disturbances affecting Mediterranean forests. The year 2017 is shaping up to be a record breaking fire season all around Southern Europe and especially in Italy for the sheer amount of hectares burned. Here we discuss about the importance of forest fire management, highlighting the role of prescribed burning and mechanical treatment (e.g., manual removal, thinning in reducing the risk of high-intensity wildfires. We report on the successful applications of those fire management techniques on the pinewoods of Vesuvio National Park and Castel Fusano Natural Reserve. The information compiled in the present article aims to demonstrate the potential relevance and impact of forest resources management for fire hazard reduction and shows the necessity of strong interaction among not only the scientific community, but also forest managers, decision makers and the civic responsibility of society at large.

  5. Lessons from the Fukushima nuclear power accident

    Hatamura, Yotaro

    2013-01-01

    Through the investigation of the Fukushima Nuclear Power Accident as the chairman of the related Government's Committee, many things had been considered. Essence of the accident could be not only what occurred in the Fukushima nuclear power station, but also dispersed radioactive materials forced many residents to move and not to be returned. Such events as indication errors of water level meter occurring in severe accident could no be thought and remote mechanical operation of valves under high radiation environment were not prepared. Contamination by radioactive clouds caused the evacuation of residents for a long period. Lessons learned from the accident were described such as; (1) the verification of the road to failure connecting selected accident sequence and road to success with another supposed choice, (2) considering what might occur and then what should be needed on the contrary, (3) nuclear power, if should be continued, should be used with the premise of its hazards, and (4) advise to nuclear engineer for adequate information dissemination and technical explanation to the public and keeping nuclear technologies alive.

  6. Intelligence and Nuclear Proliferation: Lessons Learned

    Hansen, Keith A.

    2011-09-01

    Intelligence agencies play a fundamental role in the prevention of nuclear proliferation, as they help to understand other countries' intentions and assess their technical capabilities and the nature of their nuclear activities. The challenges in this area remain, however, formidable. Past experiences and the discoveries of Iraq's WMD programs, of North Korean nuclear weapon program, and of Iranian activities, have put into question the ability of intelligence to monitor small, clandestine proliferation activities from either states or non-state entities. This Proliferation Paper analyzes the complex challenges intelligence faces and the various roles it plays in supporting national and international nuclear non-proliferation efforts, and reviews its track record. In an effort to shed light on the role and contribution of intelligence in national and international efforts to halt, if not prevent, further nuclear weapon proliferation, this paper first analyzes the challenges intelligence faces in monitoring small, clandestine proliferation activities and the role it plays in supporting non-proliferation efforts. It then reviews the intelligence track record in monitoring proliferation including the lessons learned from Iraq. Finally, it addresses whether it is possible for intelligence to accurately monitor future clandestine proliferation efforts. (author)

  7. Lessons for the control of AIDS.

    Weller, T H

    1987-11-15

    A balanced perspective that places acquired immunodeficiency syndrome (AIDS) in the context of the social needs of a global society is needed to overcome the hysteria and stigmatizing that presently surrounds this public health issue. The migration of poor, rural, sexually active young people to urban centers in the Third World has clearly played a role in the dissemination of AIDS and other infectious diseases. It is necessary, however, to examine the major cause of such population movement--private enterprise. Migrant workers are used to perform menial jobs in the urban labor force. Another cause of population movements is war and political repression. The fact that young people are becoming increasingly mobile has serious implications for the control of AIDS, and this phenomenon cannot be addressed without looking at its causes. Similarly, the disproportionate mortality of minorities- -seen in the AIDS epidemic as well--calls for discrimination. To prevent and control AIDS, the 1st step is to increase understanding of its natural history and epidemiology. Then, lessons must be learned from successful public health programs rooted in a primary health care system, including the Expanded Program on Immunization and oral rehydration campaigns. Although funds should not be diverted from such programs to combat AIDS, their logistic structure should be studied. Above all, however, it must be kept in mind that the constructive influence of health education will be thwarted as long as social inequities remain.

  8. The Tamiflu fiasco and lessons learnt.

    Gupta, Yogendra Kumar; Meenu, Meenakshi; Mohan, Prafull

    2015-01-01

    Oseltamivir (Tamiflu), a neuraminidase inhibitor, was approved for seasonal flu by US Food and Drug Administration in 1999. A number of randomized controlled trials, systematic reviews, and meta-analysis emphasized a favorable efficacy and safety profile. Majority of them were funded by Roche, which also first marketed and promoted this drug. In 2005 and 2009, the looming fear of pandemic flu led to recommendation by prominent regulatory bodies such as World Health Organization (WHO), Centers for Disease Control and Prevention, European Medicines Agency and others for its use in treatment and prophylaxis of influenza, and it's stockpiling as a measure to tide over the crisis. Serious Adverse Events, especially neuropsychiatric events associated with Tamiflu started getting reported leading to a cascade of questions on clinical utility of this drug. A recent Cochrane review and related articles have questioned the risk-benefit ratio of the drug, besides raising doubts about the regulatory decision of approving it. The recommendations for stockpiling the said drug as given by various international organizations viz WHO have also been put to scrutiny. Although many reviewers have labeled the Tamiflu saga as a "costly mistake," the episode leaves us with some important lessons. This article takes a comprehensive relook on the subject, and we proceed to suggest some ways and means to avoid a similar situation in the future.

  9. Cellular uptake: lessons from supramolecular organic chemistry.

    Gasparini, Giulio; Bang, Eun-Kyoung; Montenegro, Javier; Matile, Stefan

    2015-07-04

    The objective of this Feature Article is to reflect on the importance of established and emerging principles of supramolecular organic chemistry to address one of the most persistent problems in life sciences. The main topic is dynamic covalent chemistry on cell surfaces, particularly disulfide exchange for thiol-mediated uptake. Examples of boronate and hydrazone exchange are added for contrast, comparison and completion. Of equal importance are the discussions of proximity effects in polyions and counterion hopping, and more recent highlights on ring tension and ion pair-π interactions. These lessons from supramolecular organic chemistry apply to cell-penetrating peptides, particularly the origin of "arginine magic" and the "pyrenebutyrate trick," and the currently emerging complementary "disulfide magic" with cell-penetrating poly(disulfide)s. They further extend to the voltage gating of neuronal potassium channels, gene transfection, and the delivery of siRNA. The collected examples illustrate that the input from conceptually innovative chemistry is essential to address the true challenges in biology beyond incremental progress and random screening.

  10. Lessons learned in NEPA public involvement

    Stevens, A.D.; Glore, D.M.

    1995-01-01

    'In recent years Uncle Sam has been asking citizens for their help in improving the environment. The government is learning that with public input it can better prioritize environmental problems and more effectively direct limited funding.' The National Environmental Policy Act (NEPA), like many other government regulations, is a 'living law.' Although there are agency and Council guidelines, it is practical application, based on past practices and case law that refines the Act's broad concepts. The specifics of how to meet requirements are constantly being honed and melded to fit the unique situational needs of an agency, a project, or a public. This fluidity presents a challenge for stakeholder involvement activities. Communication practioners and project managers may have room for creativity and customized approaches, but they also find less than clear direction on what it takes to successfully avoid challenges of non-compliance. Because of the continuing uncertainty on how to involve the public meaningfully, it is vital to share important lessons learned from NEPA projects. The following practical suggestions are derived primarily from experiences with the Department of Energy's first ever complex-wide and site-specific environmental impact statement (EIS)-the Programmatic Spent Nuclear Fuel Management and Idaho National Engineering Laboratory Environmental Restoration and Waste Management Programs EIS (SNF ampersand INEL EIS)

  11. Lessons learnt from Ignalina NPP decommissioning project

    NAISSE, Jean-Claude

    2007-01-01

    The Ignalina Nuclear Power Plant (INPP) is located in Lithuania, 130 km north of Vilnius, and consists of two 1500 MWe RBMK type units, commissioned respectively in December 1983 and August 1987. On the 1. of May 2004, the Republic of Lithuania became a member of the European Union. With the protocol on the Ignalina Nuclear Power in Lithuania which is annexed to the Accession Treaty, the Contracting Parties have agreed: - On Lithuanian side, to commit closure of unit 1 of INPP before 2005 and of Unit 2 by 31 December 2009; - On European Union side, to provide adequate additional Community assistance to the efforts of Lithuania to decommission INPP. The paper is divided in two parts. The first part describes how, starting from this agreement, the project was launched and organized, what is its present status and which activities are planned to reach the final ambitious objective of a green field. To give a global picture, the content of the different projects that were defined and the licensing process will also be presented. In the second part, the paper will focus on the lessons learnt. It will explain the difficulties encountered to define the decommissioning strategy, considering both immediate or differed dismantling options and why the first option was finally selected. The paper will mention other challenges and problems that the different actors of the project faced and how they were managed and solved. The paper will be written by representatives of the Ignalina NPP and of the Project Management Unit. (author)

  12. Effective Lesson Planning: Field Trips in the Science Curriculum

    Rieger, C. R.

    2010-10-01

    Science field trips can positively impact and motivate students. However, if a field trip is not executed properly, with appropriate preparation and follow-up reinforcement, it can result in a loss of valuable educational time and promote misconceptions in the students. This study was undertaken to determine if a classroom lesson before an out-of-the-classroom activity would affect learner gain more or less than a lesson after the activity. The study was based on the immersive theater movie ``Earth's Wild Ride'' coupled with a teacher-led Power Point lesson. The participants in the study were students in a sixth grade physical science class. The order of lessons showed no detectable effect on final learner outcomes. Based on pre- and post-testing, improvement in mean learning gain came from the teacher-led lesson independent of the movie. The visit to the immersive theater, however, had significant positive effects that did not show up in the quantitative results of the testing.

    Phaikhumnam, Wuttichai; Yuenyong, Chokchai

    2018-01-01

    The study aimed to develop primary school science lesson plan based on inquiry cycle (5Es) through lesson study. The study focused on the development of 4 primary school science lesson plans of force and motion for Grade 3 students in KKU Demonstration Primary School (Suksasart), first semester of 2015 academic year. The methodology is mixed method. The Inthaprasitha (2010) lesson study cycle was implemented in group of KKU Demonstration Primary School. Instruments of reflection of lesson plan developing included participant observation, meeting and reflection report, lesson plan and other document. The instruments of examining students' learning include classroom observation and achievement test. Data was categorized from these instruments to find the issues of changing and improving the good lesson plan of Thai primary school science learning. The findings revealed that teachers could develop the lesson plans through lesson study. The issues of changing and improving were disused by considering on engaging students related to societal issues, students' prior knowledge, scientific concepts for primary school students, and what they learned from their changing. It indicated that the Lesson Study allowed primary school science teachers to share ideas and develop ideas to improve the lesson. The study may have implications for Thai science teacher education through Lesson Study.

  8. The costs of REDD: lessons from Amazonas

    Viana, Virgilio M.; Ribenboim, Gabriel [Amazonas Sustainable Foundation (Brazil); Mea, Rosana Della [Rainforest Concern (Brazil); Grieg-Gran, Maryanne

    2009-11-15

    Reducing tropical deforestation is a major climate and development issue: forest clearing is responsible for roughly a fifth of greenhouse gas emissions, and the forest-dependent poor number over a billion. In the runup to the Copenhagen climate summit, REDD – reducing emissions from deforestation and (forest) degradation by providing incentives to tropical forest countries – has been touted as one of the most cost-effective mitigation mechanisms on the table. But the benefits would be only temporary if forests saved today are cleared once incentives cease. Would the expense of maintaining such incentives over decades raise the price to uncompetitive levels? A forest reserve in Amazonas, Brazil, offers some of the first real-world data on the costs of REDD. Even with pessimistic assumptions about future pressures, the project's carbon cuts look highly affordable.

  10. Pre-equilibrium gamma emissions

    Ghosh, Sudip

    1993-01-01

    Together with the direct reaction and the compound nuclear emissions the pre-equilibrium (PEQ) or pre-compound processes give a fairly complete picture of nuclear reactions induced by light ions at energies of some tens of MeV. PEQ particle emissions covering the higher energy continuum spectra have been investigated in detail both experimentally and theoretically. In contrast, very little work has been done on PEQ γ- emissions. The reason is that in spite of extensive work done on PEQ particle emissions, the mechanism is not yet fully understood. Also, the PEQ γ-emission cross-sections (∼ micro barns) are very small compared to the PEQ particle emission cross-sections (∼ milli barns). Yet apart from the academic interest the understanding of PEQ γ-emissions is important for applied fusion research etc. In this paper the PEQ γ-emissions is discussed and the work done in this field is reviewed.

  13. Global emissions inventories

    Dignon, J.

    1995-07-01

    Atmospheric chemistry determines the concentrations of most of the important greenhouse gases except for carbon dioxide. The rate of removal of the greenhouse gases from the atmosphere is also controlled by atmospheric chemistry. The indirect effects of chemical forcing resulting from the chemical interactions of other species can also affect the concentrations of radiatively important gases such as ozone. In order to establish the contribution of any possible climatic change attributable to individual greenhouse gases, spatially and temporally resolved estimates of their emissions need to be established. Unfortunately, for most of the radiatively important species the global magnitudes of their individual fluxes are not known to better than a factor of two and their spatial distributions are even more poorly characterized. Efforts to estimate future projections of potential impacts and to monitor international agreements will require continued research to narrow the uncertainties of magnitude and geographical distribution of emissions

  14. Positron emission tomography

    Yamamoto, Y.L.; Thompson, C.J.; Diksic, M.; Meyer, E.; Feindel, W.H.

    1984-01-01

    One of the most exciting new technologies introduced in the last 10 yr is positron emission tomography (PET). PET provides quantitative, three-dimensional images for the study of specific biochemical and physiological processes in the human body. This approach is analogous to quantitative in-vivo autoradiography but has the added advantage of permitting non-invasive in vivo studies. PET scanning requires a small cyclotron to produce short-lived positron emitting isotopes such as oxygen-15, carbon-11, nitrogen-13 and fluorine-18. Proper radiochemical facilities and advanced computer equipment are also needed. Most important, PET requires a multidisciplinary scientific team of physicists, radiochemists, mathematicians, biochemists and physicians. The most recent trends are reviewed in the imaging technology, radiochemistry, methodology and clinical applications of positron emission tomography. (author)

  15. Forecasting carbon dioxide emissions.

    Zhao, Xiaobing; Du, Ding

    2015-09-01

    This study extends the literature on forecasting carbon dioxide (CO2) emissions by applying the reduced-form econometrics approach of Schmalensee et al. (1998) to a more recent sample period, the post-1997 period. Using the post-1997 period is motivated by the observation that the strengthening pace of global climate policy may have been accelerated since 1997. Based on our parameter estimates, we project 25% reduction in CO2 emissions by 2050 according to an economic and population growth scenario that is more consistent with recent global trends. Our forecasts are conservative due to that we do not have sufficient data to fully take into account recent developments in the global economy. Copyright © 2015 Elsevier Ltd. All rights reserved.

  16. Lessons Learned from Real-Time, Event-Based Internet Science Communications

    Phillips, T.; Myszka, E.; Gallagher, D. L.; Adams, M. L.; Koczor, R. J.; Whitaker, Ann F. (Technical Monitor)

    2001-01-01

    For the last several years the Science Directorate at Marshall Space Flight Center has carried out a diverse program of Internet-based science communication. The Directorate's Science Roundtable includes active researchers, NASA public relations, educators, and administrators. The Science@NASA award-winning family of Web sites features science, mathematics, and space news. The program includes extended stories about NASA science, a curriculum resource for teachers tied to national education standards, on-line activities for students, and webcasts of real-time events. The focus of sharing science activities in real-time has been to involve and excite students and the public about science. Events have involved meteor showers, solar eclipses, natural very low frequency radio emissions, and amateur balloon flights. In some cases, broadcasts accommodate active feedback and questions from Internet participants. Through these projects a pattern has emerged in the level of interest or popularity with the public. The pattern differentiates projects that include science from those that do not, All real-time, event-based Internet activities have captured public interest at a level not achieved through science stories or educator resource material exclusively. The worst event-based activity attracted more interest than the best written science story. One truly rewarding lesson learned through these projects is that the public recognizes the importance and excitement of being part of scientific discovery. Flying a camera to 100,000 feet altitude isn't as interesting to the public as searching for viable life-forms at these oxygen-poor altitudes. The details of these real-time, event-based projects and lessons learned will be discussed.

    2013-11-01

    Full Text Available In the information era that we experience today, there is a rapid change in the methods, techniques and materials used for education and teaching. The usage of information and communication technology-assisted teaching materials are becoming more commonplace. Parallel to these developments, the Ministry of National Education took steps to develop IT substructures of all schools in the country and implemented many projects. The purpose of this study is to determine whether or not the multimedia lesson content used by teachers affect effective learning. This study is a qualitative study, conducted with 45 teachers working in primary schools during the 2011-2012 academic year. According to the study findings, participants believe that using multimedia lesson content during lectures increases student motivation, makes students more curious and interested, and think that using multimedia lesson content has positive effects.

  1. The relationships within the mathematical content of teachers’ lesson sequences

    Shahrill, M.; Prahmana, R. C. I.; Roslan, R.

    2017-12-01

    This study explored how mathematics content is carried through by means of the problems presented during lessons. Following the definitions and the coding criteria from the TIMSS 1999 Video Study, a total of 163 mathematics problems were identified in the video- recorded lesson sequences of four Bruneian mathematics teachers teaching at the Year 8 level. These problems were classified according to the four basic kinds of relationships: mathematically related, thematically related, repetition and unrelated. Drawing on the mathematical content of the teachers’ lesson sequences, the findings revealed variations among the mathematical problems coded as repetition and thematically related, between the four Brunei classes. The aggregated results obtained from the four classes highlighted several points of discussion, such as the relatively higher proportion of repetition problems (52%) from one teacher in particular; the percentage similarities of thematically related problems for all four classes (ranging from 26% to 33%); and the incredibly varied results for mathematically related problems across the four Brunei classes.

  2. Lessons learned from radiological accidents at medical exposures in radiotherapy

    Fagundes, J.S.; Ferreira, A.F.; Lima, C.M.A.; Silva, F.C.A. da

    2017-01-01

    An exposure is considered accidental in radiotherapy when there is a substantial deviation in the prescription of treatment. In this work, an analysis of published radiological accidents, both in Brazil and internationally, was performed during medical exposures in radiotherapy treatments, removing the main lessons learned. Of the research carried out, we highlight Brazil with four radiological accidents and one death in the period between 2011 and 2014; the United States of America with 169 accidents with two deaths from 2000 to 2010 and France from 2001 to 2014 had 569 deaths without patients. Lessons learned have been described, for example, that maintenance personnel training should specify limitations or restrictions on the handling or adjustment of critical parts on the accelerator. It is recommended to apply the 10 main lessons learned due to radiological accidents during medical exposures in radiotherapy treatments to avoid future events

    Electron field emission limits the accelerating gradient in superconducting cavities. It is shown how and why it is an important problem. The phenomenology of field emission is then described, both in DC and RF regimes. Merits of a few plausible 'remedies' to field emission are discussed. (author)

  4. Emission trading: A discussion paper

    1992-05-01

    Emission trading is a market-based incentive program designed to control air emissions in which a cap is placed on the total quantity of pollutants allowed to be emitted in an airshed. Appropriate shares of this amount are allocated among participating emission sources, and participants can buy or sell their shares. Advantages of emission trading include its potential to achieve air emission targets at a lower cost than the traditional command and control approach, and its ability to accommodate economic growth without compromising environmental quality. A study was conducted to evaluate the potential use of emission trading programs to achieve emission reduction goals set for nitrogen oxides, volatile organic compounds (VOC), and sulfur oxides. Emission trading programs in the USA are reviewed and a set of factors important for the success of emission trading are identified. Key policy and design issues related to an emission trading program are identified, explained, and discussed. Administrative issues are then analyzed, such as legislative authority, monitoring and enforcement requirements, and trading between jurisdictions. A preliminary assessment of emission trading for control of NOx and VOC in the Lower Fraser Valley indicates that emission trading would be feasible, but legislative authority to implement such a program would have to be introduced

  5. Emissions trading stalls

    Milne, R.

    1998-01-01

    A brief article examines prospects for emission trading of greenhouse gas emissions in the UK. Topics covered include a checklist of principles for any trading system, plans for oil companies to do it internally, the possibility for carbon sinks as well as emissions and developments around the world. (UK) alt. Directly northward of the Sigsbee Escarpment, there is a relatively thin, low-velocity zone known as a ''gumbo zone''. Here two other pressure compartments are proposed. The origin of them is two-fold. First, initial sedimentation consists of pelagic clay draped over oceanic and transitional crust. Later, as the continental margin progrades nearer sedimentation becomes hemipelagic and coarser as gravity-driven sediments predominate. Secondly, as the salt wedge overrides a given spot of the basement, it is possible to develop a shear couple between the migrating salt and the stationary basement. The resultant shear (the site of the next strike-slip fault) may change pressures beneath the salt such that the shear may create two pressure compartments. The differences between the two compartments may be accentuated by lithologic changes caused by depositional mechanisms. (author)

  6. Graduate students teaching elementary earth science through interactive classroom lessons

    Caswell, T. E.; Goudge, T. A.; Jawin, E. R.; Robinson, F.

    2014-12-01

    Since 2005, graduate students in the Brown University Department of Earth, Environmental, and Planetary Studies have volunteered to teach science to second-grade students at Vartan Gregorian Elementary School in Providence, RI. Initially developed to bring science into classrooms where it was not explicitly included in the curriculum, the graduate student-run program today incorporates the Providence Public Schools Grade 2 science curriculum into weekly, interactive sessions that engage the students in hypothesis-driven science. We will describe the program structure, its integration into the Providence Public Schools curriculum, and 3 example lessons relevant to geology. Lessons are structured to develop the students' ability to share and incorporate others' ideas through written and oral communication. The volunteers explain the basics of the topic and engage the students with introductory questions. The students use this knowledge to develop a hypothesis about the upcoming experiment, recording it in their "Science Notebooks." The students record their observations during the demonstration and discuss the results as a group. The process culminates in the students using their own words to summarize what they learned. Activities of particular interest to educators in geoscience are called "Volcanoes!", "The "Liquid Race," and "Phases of the Moon." The "Volcanoes!" lesson explores explosive vs. effusive volcanism using two simulated volcanoes: one explosive, using Mentos and Diet Coke, and one effusive, using vinegar and baking soda (in model volcanoes that the students construct in teams). In "Liquid Race," which explores viscosity and can be integrated into the "Volcanoes!" lesson, the students connect viscosity to flow speed by racing liquids down a ramp. "Phases of the Moon" teaches the students why the Moon has phases, using ball and stick models, and the terminology of the lunar phases using cream-filled cookies (e.g., Oreos). These lessons, among many others

    2010-03-01

    Influences of electric fields on the emission from organic light-emitting diodes (OLEDs) based on poly (N-vinylcarbazole) (PVK); 2, 9-dimethyl-4, 7-diphenyl-1, 10-phenanthroline (BCP); and tris (8-hydroxyquinoline) aluminum (Alq3) were studied. There are three emission peaks at 420 nm, 520 nm, and 620 nm of the device ITO/PEDOT: PSS/PVK/BCP/LiF/Al under different driving voltages. The emissions at 420 nm and 520 nm should be from the exciton emission of PVK and Alq3, respectively. The last emission at 620 nm could be attributed to electroplex emission at the interface between the PVK and BCP layers. A high intensity white emission via electroplex formation was obtained with Commission International d'Eclairage (CIE) coordinates (0.33, 0.34) at 15 V, which is very close to the equienergy white point (0.33, 0.33).

  8. Emission inventory for fugitive emissions from fuel in Denmark

    Plejdrup, Marlene Schmidt; Nielsen, Ole-Kenneth; Nielsen, Malene

    This report presents the methodology and data used in the Danish inventory of fugitive emissions from fuels for the years until 2013. The inventory of fugitive emissions includes CO2, CH4, N2O, SO2, NOx, NMVOC, CO, particulate matter, Black carbon, heavy metals, dioxin and PAHs. In 2013 the total...... Danish emission of greenhouse gasses was 54 584 Gg CO2 equivalents. Fugitive emissions from fuels account for 387 Gg CO2 equivalents or approximately 1 %. The major part of the fugitive emissions are emitted as CO2 (61 %) mainly from flaring in upstream oil and gas production. The major source...... of fugitive CH4 emission is production of oil and gas in the North Sea, refining of oil and loading of oil onto ships both offshore and onshore. The fugitive emissions of NMVOC originate for the major part from oil and gas production, loading of ships, transmission and distribution of oil, and to a less...

  9. Mapping UV properties throughout the Cosmic Horseshoe: lessons from VLT-MUSE

    James, Bethan L.; Auger, Matt; Pettini, Max; Stark, Daniel P.; Belokurov, V.; Carniani, Stefano

    2018-05-01

    We present the first spatially resolved rest-frame ultraviolet (UV) study of the gravitationally lensed galaxy, the `Cosmic Horseshoe' (J1148+1930) at z = 2.38. Our gravitational lens model shows that the system is made up of four star-forming regions, each ˜4-8 kpc2 in size, from which we extract four spatially exclusive regional spectra. We study the interstellar and wind absorption lines, along with C III] doublet emission lines, in each region to investigate any variation in emission/absorption line properties. The mapped C III] emission shows distinct kinematical structure, with velocity offsets of ˜±50 km s-1 between regions suggestive of a merging system, and a variation in equivalent width that indicates a change in ionization parameter and/or metallicity between the regions. Absorption line velocities reveal a range of outflow strengths, with gas outflowing in the range -200 ≲ v (km s-1) ≲ -50 relative to the systemic velocity of that region. Interestingly, the strongest gas outflow appears to emanate from the most diffuse star-forming region. The star formation rates remain relatively constant (˜8-16 M⊙ yr-1), mostly due to large uncertainties in reddening estimates. As such, the outflows appear to be `global' rather than `locally' sourced. We measure electron densities with a range of log (Ne) = 3.92-4.36 cm-3, and point out that such high densities may be common when measured using the C III] doublet due to its large critical density. Overall, our observations demonstrate that while it is possible to trace variations in large-scale gas kinematics, detecting inhomogeneities in physical gas properties and their effects on the outflowing gas may be more difficult. This study provides important lessons for the spatially resolved rest-frame UV studies expected with future observatories, such as James Webb Space Telescope.

  10. Assessing the Climate Impacts of Cookstove Projects: Issues in Emissions Accounting

    Carrie M. Lee

    2014-03-01

    Full Text Available An estimated 2.6 billion people rely on traditional biomass for home cooking and heating, so improving the efficiency of household cookstoves could provide significant environmental, social and economic benefits. Some researchers have estimated that potential greenhouse gas emission reductions could exceed 1 billion tons of carbon dioxide equivalent (CO2e per year. Carbon finance offers a policy mechanism for realizing some of this potential and could also bring improved monitoring to cookstove projects. However, there are formidable methodological challenges in estimating emission reductions. This paper evaluates the quantification approaches to three key variables in calculating emission impacts: biomass fuel consumption, fraction of non-renewable biomass, and emission factors for fuel consumption. It draws on a literature review as well as on interviews with technical experts and market actors, and identifies lessons learned and knowledge gaps. Key research needs identified include incorporating accounting for uncertainty; development of additional default factors for biomass consumption for baseline stoves; refinement of monitoring approaches for cookstove use; broadened scope of emission factors used for cookstoves; accounting for non-CO2 gases and black carbon; and refinement of estimates and approaches to considering emissions from bioenergy use across methodologies.

  11. Stand-alone photovoltaic applications. Lessons learned

    Loois, G.; Van Hemert, B.

    1999-02-01

    The IEA Photovoltaic Power Systems Programme (PVPS) is one of the collaborative R and D agreements established within the IEA. The objective of Task III is to promote and facilitate the exchange of information and experiences in the field of PV Systems in Stand-alone and Island Applications (SAPV). The book focuses on the practical experiences gained, and does not aim to provide a complete manual on SAPV. When Task III started its activities in 1993, a collection of 50 'State of the art' projects was published in the book 'Examples of Stand-Alone Photovoltaic Systems'. This publication marked the base line for the work of the task. Now, in 1998, the showcases from each country demonstrate the lessons learned in five years of cooperation. The book consists of two parts. The first part contains eight chapters dealing with a specific aspect of stand-alone PV. The second part introduces 14 national showcase projects in a systematic presentation. Each chapter and showcase can be read independently from the rest of the book. Chapter 2, contributed by The Netherlands, analyses the market for stand-alone PV systems. It gives an overview of the 'traditional' application of stand-alone PV, which is the electrification of remote buildings and which has been addressed in depth in other publications. The focus is on the market niches of service applications that are also interesting for more densely populated areas, e.g. in industrialised countries. The United Kingdom illustrates the economic aspects in Chapter 3. Cost comparisons are made, but more important is the illustration of the non-financial considerations that make PV the preferred choice as a power source for many applications. Switzerland explores in Chapter 4 (financing aspects) different financing mechanisms, and financial policies used to overcome the initial cost barrier. Most of these approaches have been applied in developing countries rather than in the western world. Using various examples from all over the

  12. What lessons can history teach us about the Charcot foot?

    Sanders, Lee J

    2008-01-01

    Regrettably, physicians today receive very little instruction in the history of medicine. Most health care providers have a very limited, contemporary knowledge of the condition that we know of as the Charcot foot. Yet, historical concepts of the pathogenesis and natural history of this condition provide us with important lessons that enhance our understanding, recognition, and management of this rare but debilitating neurogenic arthropathy. It is my belief that knowledge of the history of medicine provides us with a better understanding of present-day issues and clearer vision as we look to the future. This article describes some of the important lessons learned from the history of the Charcot foot.

    1998-09-01

    Renewable energy solutions for village power applications can be economical, functional, and sustainable. Pilot projects are an appropriate step in the development of a commercially viable market for rural renewable energy solutions. Moreover, there are a significant number of rural electrification projects under way that employ various technologies, delivery mechanisms, and financing arrangements. These projects, if properly evaluated, communicated, and their lessons incorporated in future projects and programs, can lead the way to a future that includes a robust opportunity for cost-effective, renewable-based village power systems. This paper summarizes some of NREL`s recent experiences and lessons learned.

  17. Crisis communication. Lessons from 9/11.

    Argenti, Paul

    2002-12-01

    The sheer enormity of last year's terrorist attacks on the World Trade Center and the Pentagon gave new meaning to the term "crisis management." Suddenly, companies near Ground Zero, as well as those more than a thousand miles away, needed a plan. Because the disasters disrupted established channels not only between businesses and customers but between businesses and employees, internal crisis-communications strategies that could be quickly implemented became a key responsibility of top management. Without these strategies, employees' trauma and confusion might have immobilized their firms and set their customers adrift. In this article, executives from a range of industries talk about how their companies, including Morgan Stanley, Oppenheimer Funds, American Airlines, Verizon, the New York Times, Dell, and Starbucks, went about restoring operations and morale. From his interviews with these individuals, author and management professor Paul Argenti was able to distill a number of lessons, each of which, he says, may "serve as guideposts for any company facing a crisis that undermines its employees' composure, confidence, or concentration." His advice to senior executives includes: Maintain high levels of visibility, so that employees are certain of top management's command of the situation and concern; establish contingency communication channels and work sites; strive to keep employees focused on the business itself, because a sense of usefulness enhances morale and good morale enhances usefulness; and ensure that employees have absorbed the firm's values, which will guide them as they cope with the unpredictable. The most forward-thinking leaders realize that managing a crisis-communications program requires the same dedication and resources they give to other dimensions of their business. More important, they realize that their employees always come first.

  18. Lessons learned from accidental exposures in radiotherapy

    2000-01-01

    The medical use of radiation is unique in that patients are intentionally exposed to radiation. The aim in radiation therapy is twofold: to deliver a dose and dose distribution that is adequate for tumour control, but which also minimizes complications in normal tissues. In therapeutic applications, the doses are high and a deviation from the prescribed dose may have severe or even fatal consequences. There is therefore a great need to ensure adequate radiation protection and safety in radiotherapy by verifying that all personnel involved are appropriately trained for their duties, that the equipment used meets relevant international specifications for radiation safety and that safety culture is embedded in routine activities in radiotherapy departments. Many individuals must interact and work together on highly technical measurements and calculations, and therefore the potential for mistakes is great. A review of the mistakes shows that most are due to human error. The International Basic Safety Standards for Protection against Ionizing Radiation and the Safety of Radiation Sources (IAEA Safety Series No. 115) require that a prompt investigation be conducted whenever an accidental medical exposure of patients occurs. The report of the investigation is to be disseminated to the appropriate parties so that lessons can be learned to prevent similar accidents or mitigate their consequences in the future. This Safety Report is a collection of a large number of events that may serve as a checklist against which to test the vulnerability of a facility to potential accidents, and to provide a basis for improving safety in the use of radiation in medical applications. A further purpose of this report is to encourage readers to develop a questioning and learning attitude, adopt measures for the prevention of accidents, and prepare for mitigation of the consequences of accidents if they occur

  19. Integrated Programme Control Systems: Lessons Learned

    Brown, C. W. [Babcock International Group PLC (formerly UKAEA Ltd) B21 Forss, Thurso, Caithness, Scotland (United Kingdom)

    2013-08-15

    Dounreay was the UK's centre of fast reactor research and development from 1955 until 1994 and is now Scotland's largest nuclear clean up and demolition project. After four decades of research, Dounreay is now a site of construction, demolition and waste management, designed to return the site to as near as practicable to its original condition. Dounreay has a turnover in the region of Pounds 150 million a year and employs approximately 900 people. It subcontracts work to 50 or so companies in the supply chain and this provides employment for a similar number of people. The plan for decommissioning the site anticipates all redundant buildings will be cleared in the short term. The target date to achieve interim end state by 2039 is being reviewed in light of Government funding constraints, and will be subject to change through the NDA led site management competition. In the longer term, controls will be put in place on the use of contaminated land until 2300. In supporting the planning, management and organisational aspects for this complex decommissioning programme an integrated programme controls system has been developed and deployed. This consists of a combination of commercial and bespoke tools integrated to support all aspects of programme management, namely scope, schedule, cost, estimating and risk in order to provide baseline and performance management data based upon the application of earned value management principles. Through system evolution and lessons learned, the main benefits of this approach are management data consistency, rapid communication of live information, and increased granularity of data providing summary and detailed reports which identify performance trends that lead to corrective actions. The challenges of such approach are effective use of the information to realise positive changes, balancing the annual system support and development costs against the business needs, and maximising system performance.

  20. Lessons Learnt of Thai Women Environmental Leaders

    Sittipong Dilokwanich

    2015-07-01

    Full Text Available During the past few decades, Thai women have learned how to extent their roles from a care taker of children and a household to natural resources and environmental protection and management in local and inter-regional communities. Due to the application of National Economic and Social Development Plans, rapid resource exploitation has brought in natural resource and environmental degradation all over the country threatening communal security. For this reason, there have been a number of emerging environmental leaders who want to correct directions of national development, especially Thai woman environmental leaders who are taking a successful role of environmental guardian in their communities. This research attempts to explore why they took leadership role in environment, how they work so successful as an environmental guardian, and what their next move is. During early 2013 till mid-2014, there are 28 Thai woman leaders who received the award of Thai Environmental Conservation Mother from the Faculty of Environment and Resource Studies, Mahidol University between 2004 and 2012. They were in-depth interviewed and collected data were preceded by content analysis. Their lessons learnt show that most leaders saved their communities' environment and natural resources from the intervention of new development activities. Most of them had their parents as a good role model in environmental management who provide knowledge of morals and environmental ethics as a good basic of leadership while some shared their husband's responsibility in the same matter. Significantly, teamwork is their working style with the assistance of public participation to hold teamwork and collaboration of the community. Almost all leaders had systematic working with talents of patience, gentleness and sensitivity. The working network also broadens their new information and knowledge between practitioners. In the same time, more than half of the leaders can prepare their

    2013-04-01

    Full Text Available Despite some school efforts to offer students the best second language learning, English language lessons are often taught with an overuse of the mother tongue. Hence, an action research project was conducted in order to discover how to adapt some features of the Sheltered Instruction Observation Protocol (SIOP component: Lesson delivery, for the teaching of English in sixth grade at a public school in Bogotá, Colombia. Data collection included observation checklists, field notes, surveys and artifacts. The findings demonstrated that the overuse of Spanish–the students’ mother tongue–was reduced when in addition to implementing the lesson delivery component, the teacher developed vocabulary activities. Finally, it was suggested that teachers have SIOP training for teaching content andto focus more on students needs.A pesar de algunos esfuerzos para ofrecer a los estudiantes un mejor aprendizaje de una segunda lengua, a menudo se recurre al uso excesivo de la lengua materna en las clases de inglés. Con el objetivo de hallar la forma de adaptar algunas características del componente del protocolo deobservación SIOP para la instrucción ‘Sheltered’: Desarrollo de clase, para la enseñanza de inglés en grado séptimo, se realiz�� un proyecto de investigación acción en un colegio público en Bogotá, Colombia. En la recolección de datos se emplearon formatos de observación, notas de campo,cuestionarios y evidencias documentales. Los resultados demostraron que el uso excesivo de español –la lengua materna de los estudiantes– se redujo porque además de la implementación del componente Desarrollo de clase, se llevaron a cabo actividades de vocabulario. Con esta investigación se sugiere que los profesores adquieran conocimientos acerca del citado modelo para la enseñanza de contenidos, y que se enfoquen más en las necesidades de los estudiantes.

  2. Beyond the Inventory: An Interagency Collaboration to Reduce Greenhouse Gas Emissions in the Greater Yellowstone Area

    Kandt, A.; Hotchkiss, E.; Fiebig, M.

    2010-10-01

    As one of the largest, intact ecosystems in the continental United States, land managers within the Greater Yellowstone Area (GYA) have recognized the importance of compiling and understanding agency greenhouse gas (GHG) emissions. The 10 Federal units within the GYA have taken an active role in compiling GHG inventories on a unit- and ecosystem-wide level, setting goals for GHG mitigation, and identifying mitigation strategies for achieving those goals. This paper details the processes, methodologies, challenges, solutions, and lessons learned by the 10 Federal units within the GYA throughout this ongoing effort.

  3. Summary of Session 1 'Lessons from 2011'

    Lamont, M; Bracco, C [European Organization for Nuclear Research, Geneva (Switzerland)

    2012-07-01

    Review of 2011 LHC Run from The Experiments Perspective, M. Ferro-Luzzi (PH-LBD): M. Ferro-Luzzi highlighted the excellent performance of the machine and the experiments in 2011 and the fast and impressive achievements both when operating with protons and Pb ions. In a month the same luminosity as during the full 2010 proton run was delivered, and a factor 16 higher luminosity was produced with Pb ions. The excellent machine performance allowed ATLAS and CMS to make interesting observations in the context of the Higgs’ boson search and LHCb found some evidence of CP violation in time-integrated D0 which could open the way for a new physics. Input from Evian, M. Lamont (BE-OP): M. Lamont presented a summary of what discussed in Evian about lessons learnt during 2011 operation and improvements foreseen for 2012. He underlined that 2011 was a remarkable year with a continuously faster increase in luminosity production and without real show stoppers. The machinewas characterized by operational robustness, a good reproducibility, stability, beam lifetime, optics control and an excellent performance of the Machine Protection system (MPs) and of the injectors. The 2011 Run: Availability Analysis, A. Macpherson (BE-OP): A. Macpherson spoke about machine availability in 2011 and gave some statistics of fills for p-p and Pb-Pb runs. He calculated a machine availability of 76.7% and that 33% of the operation time was spent in stable beam. The Hubner factor, which gives an estimate of the luminosity production duration, was slightly bigger than the expected 0.2 value both for the proton (0.22) and lead ion (0.24) runs. Stable beams lasted in average ∼6 hours but about 50% of the fills were shorter than 4 hours. Injection and Lessons for 2012, C. Bracco (TE-ABT): C. Bracco made a presentation on the performance of the injection system. The injection of 144 bunches became fully operational in 2011 in agreement with what predicted during the last Chamonix workshop. Moreover

  5. A Text Mining Approach for Extracting Lessons Learned from Project Documentation: An Illustrative Case Study

    Benjamin Matthies

    2017-12-01

    Full Text Available Lessons learned are important building blocks for continuous learning in project-based organisations. Nonetheless, the practical reality is that lessons learned are often not consistently reused for organisational learning. Two problems are commonly described in this context: the information overload and the lack of procedures and methods for the assessment and implementation of lessons learned. This paper addresses these problems, and appropriate solutions are combined in a systematic lesson learned process. Latent Dirichlet Allocation is presented to solve the first problem. Regarding the second problem, established risk management methods are adapted. The entire lessons learned process will be demonstrated in a practical case study

  7. Sulfur dioxide control in China: policy evolution during the 10th and 11th Five-year Plans and lessons for the future

    China's Central government established national goals to reduce sulfur dioxide (SO 2 ) emissions by 10% in both the 10th and 11th Five-year Plan periods, 2001–2005 and 2006–2010, respectively. But the early policies were unsuccessful at reducing emissions—emissions increased 28% during the 10th Five-year Plan. After adapting a number of policies and introducing new instruments during the 11th Five-year Plan, SO 2 emissions declined by 14%. We examine the evolution of these policies, their interplay with technical and institutional factors, and capture lessons from the 11th Five-year Plan to guide future pollution control programs. We find that several factors contributed to achievement of the 11th Five-year Plan SO 2 reduction goal: (1) instrument choice, (2) political accountability, (3) emission verification, (4) political support, (5) streamlined targets, and (6) political and financial incentives. The approach integrated multiple policy instruments—market-based, command-and-control, and administrative instruments specific to the Chinese context. The evolution of SO 2 reduction policies and programs has implications for further SO 2 reductions from power plants and other sources, as well as control of other atmospheric pollutants such as nitrogen oxides (NO X ) and carbon dioxide (CO 2 ) in China. - Highlights: ► This paper assesses China's SO 2 reduction policies between 2000 and 2010. ► Government used a variety of policy instruments to achieve emission targets. ► Experience shows that accountability, incentives, and political support were key. ► The policy lessons can aid future policies for SO 2 , NO x , and CO 2 reductions.

  8. 1972-1997, Twenty-five years of energy and environmental history : lessons learned.

    Drucker, H.

    1997-12-17

    Given the events of the past 25 years concerning energy and environmental issues and our reaction to them, what lessons can we learn? First, the individual American consumer wants and expects energy to be a stable commodity with low prices and easy availability. As evidenced by the heated debate over increasing the federal gasoline tax by $.05 per gallon (which would still leave Americans paying only one-third of what Europeans pay for gasoline), increases in energy prices elicit very strong public and political opposition. As further evidence, it has been argued that the general public support of the Gulf War was due, in part, to a recognition of the need to maintain a stable source of cheap oil from the region. The American public wants to maintain the benefits of cheap and abundant energy and expects its political leaders to make it happen. A second lesson is that if constraints on the energy supply do occur (e.g., the OPEC-imposed oil embargo) ardor environmental impacts from energy use do appear to be significant (e.g., SO{sub 2} and CO{sub 2} emissions), the preference is for a technology fix rather than a behavioral change. This is evidenced by our reliance on moving low-sulfur coal more than 1,000 miles from Wyoming to burn in Illinois power plants rather than reducing the demand for electricity with energy-efficient measures in residential, commercial, and industrial activities. National research programs to produce an automobile that gets 80+ miles per gallon take higher priority over working to get people to use mass transit to reduce their driving mileage. Americans expect that advanced technology can be relied upon to come up with solutions to energy and environmental problems without having to change their lifestyles. The experience with natural gas, in which a regulatory change (deregulation) was combined with technology developments (horizontal drilling and improved gas turbines for electricity generation) to increase available supply and hold

  9. Aspects related to 'emission trading'

    Tutuianu, Ovidiu

    1999-01-01

    The paper presents the aspects of international GHG (greenhouse gases) emission trading, such as: quality of GHG emission data, possible partners, monitoring activity, market mechanisms and difficulties. The following conclusions are drown: - debates on international trade with GHG emissions are currently in a very early stage; - actions are possible and feasible, particularly after Kyoto Conference, as versatile mechanism (besides the Joint Implementation Projects) which have in view the lowering of the global emission costs in different zones of the planet; - difficulties concerning monitoring, reporting and verification, practically preclude implementing a system of emission trading covering all the GHG, all the sources and reservoirs; - an international viable system of emission trading could initiate with a limited number of participants and consideration of only emission categories easy to be confined and surveyed; - existence of a national market and corresponding institutions for monitoring which could booster an international system development

  10. Lessons offered, lessons learned: reflections on how doing family therapy can affect therapists.

    Heatherington, Laurie; Friedlander, Myrna L; Diamond, Gary M

    2014-08-01

    Only in working conjointly with couples and families do therapists literally witness clients struggling to improve their most intimate relationships. In writing this article, we realized that, in true systemic fashion, not only have many of our clients benefited from working with us, but also we have learned some invaluable lessons from them. Indeed, practicing couple and family therapy gives therapists many opportunities to learn about themselves, especially when it is done thoughtfully. In this article, we reflect on myriad ways in which couples and family therapy has affected each of us personally-as individuals, as partners, as parents, as adult children in our families of origin, and as educators. © 2014 Wiley Periodicals, Inc.

    Welch, M.J.

    1990-01-01

    Positron emission tomography (PET) assesses biochemical processes in the living subject, producing images of function rather than form. Using PET, physicians are able to obtain not the anatomical information provided by other medical imaging techniques, but pictures of physiological activity. In metaphoric terms, traditional imaging methods supply a map of the body's roadways, its, anatomy; PET shows the traffic along those paths, its biochemistry. This document discusses the principles of PET, the radiopharmaceuticals in PET, PET research, clinical applications of PET, the cost of PET, training of individuals for PET, the role of the United States Department of Energy in PET, and the futures of PET. 22 figs

  13. Acoustic emission intrusion detector

    Carver, D.W.; Whittaker, J.W.

    1980-01-01

    An intrusion detector is provided for detecting a forcible entry into a secured structure while minimizing false alarms. The detector uses a piezoelectric crystal transducer to sense acoustic emissions. The transducer output is amplified by a selectable gain amplifier to control the sensitivity. The rectified output of the amplifier is applied to a Schmitt trigger circuit having a preselected threshold level to provide amplitude discrimination. Timing circuitry is provided which is activated by successive pulses from the Schmitt trigger which lie within a selected time frame for frequency discrimination. Detected signals having proper amplitude and frequency trigger an alarm within the first complete cycle time of a detected acoustical disturbance signal

    1978-01-01

    In order to improve the security of handling special nuclear materials at the Oak Ridge Y-12 Plant, a sensitive acoustic emission detector has been developed that will detect forcible entry through block or tile walls, concrete floors, or concrete/steel vault walls. A small, low-powered processor was designed to convert the output from a sensitive, crystal-type acoustic transducer to an alarm relay signal for use with a supervised alarm loop. The unit may be used to detect forcible entry through concrete, steel, block, tile, and/or glass

    Paans, A M J

    2006-01-01

    Positron Emission Tomography (PET) is a method for measuring biochemical and physiological processes in vivo in a quantitative way by using radiopharmaceuticals labelled with positron emitting radionuclides such as 11C, 13N, 15O and 18F and by measuring the annihilation radiation using a coincidence technique. This includes also the measurement of the pharmacokinetics of labelled drugs and the measurement of the effects of drugs on metabolism. Also deviations of normal metabolism can be measured and insight into biological processes responsible for diseases can be obtained. At present the combined PET/CT scanner is the most frequently used scanner for whole-body scanning in the field of oncology.

  17. VOC emissions control systems

    Spessard, J.E.

    1993-01-01

    The air pollution control equipment marketplace offers many competing technologies for controlling emissions of volatile organic compounds (VOC) in air. If any technology was economically and technically superior under all conditions, it would be the only one on the market. In fact, each technology used to control VOCs is superior under some set of conditions. The reasons for choosing one control technology over another are situation-specific. Some general guidelines to VOC control technologies and the situations where each may be appropriate are presented in this article. The control technologies and applications are summarized in a table
