  1. Twenty-Five Year Site Plan FY2013 - FY2037

    Energy Technology Data Exchange (ETDEWEB)

    Jones, William H. [Los Alamos National Laboratory

    2012-07-12

    Los Alamos National Laboratory (the Laboratory) is the nation's premier national security science laboratory. Its mission is to develop and apply science and technology to ensure the safety, security, and reliability of the United States (U.S.) nuclear stockpile; reduce the threat of weapons of mass destruction, proliferation, and terrorism; and solve national problems in defense, energy, and the environment. The fiscal year (FY) 2013-2037 Twenty-Five Year Site Plan (TYSP) is a vital component for planning to meet the National Nuclear Security Administration (NNSA) commitment to ensure the U.S. has a safe, secure, and reliable nuclear deterrent. The Laboratory also uses the TYSP as an integrated planning tool to guide development of an efficient and responsive infrastructure that effectively supports the Laboratory's missions and workforce. Emphasizing the Laboratory's core capabilities, this TYSP reflects the Laboratory's role as a prominent contributor to NNSA missions through its programs and campaigns. The Laboratory is aligned with Nuclear Security Enterprise (NSE) modernization activities outlined in the NNSA Strategic Plan (May 2011) which include: (1) ensuring laboratory plutonium space effectively supports pit manufacturing and enterprise-wide special nuclear materials consolidation; (2) constructing the Chemistry and Metallurgy Research Replacement Nuclear Facility (CMRR-NF); (3) establishing shared user facilities to more cost effectively manage high-value, experimental, computational and production capabilities; and (4) modernizing enduring facilities while reducing the excess facility footprint. Th is TYSP is viewed by the Laboratory as a vital planning tool to develop an effi cient and responsive infrastructure. Long range facility and infrastructure development planning are critical to assure sustainment and modernization. Out-year re-investment is essential for sustaining existing facilities, and will be re-evaluated on an annual

  2. Twenty years of JHEP

    International Nuclear Information System (INIS)

    Amati, Daniele; Bonora, Loriano

    2017-01-01

    On July 1st of twenty years ago we launched the first issue of JHEP. It was a real challenge to try the adventure of a scientific journal thought and managed by scientists, independent of private or institutional publishers. The idea was that physicists who were performing the work, writing the papers, and refereeing those of their peers, could also edit them in an electronic format. Thus, at a limited cost which could be handled by academic or scientific institutions, giving open access to the published information, and avoiding the heavy burden at that time placed on our libraries. In order to avoid the failure that - as we well remember was predicted to us by publishing companies and institutions, we needed the active support of the scientific community. A support in collaborating to the scrutiny of papers and scientific policies but, mainly, in sending to us their good papers. We contacted in that sense several of our most active and renowned colleagues, restricting of course to our high energy physics field. We received many enthusiastic responses as can be specifically seen from the papers that appear in the first issues of the journal, as well as the respected names listed in the advisory and in the editorial boards featuring in the opening page of the first issue of JHEP attached to this letter. We were optimists, but perhaps not as much as to foresee the success of the journal, which, in his first 20 years, turned out to be one of the most (if not the most) prestigious one in our field. Success for which --- as first project chairman and executive editor - we must essentially thank the scientific community who supported JHEP by considering it ''their journal'', as was our intention from the start. In this occasion we would like to recall the important contribution of Marco Fabbrichesi who designed the software on which the journal is based, and the technical personnel who implemented it and made it work. It is our pleasure to mention

    A study is presented of people who were supporters or leaders in the Campaign for Nuclear Disarmament (CND) in the 1950s and 1960s. Information is given from questionnaires completed by 403 respondents, about their social and political development during the past 20 years. (author)

  4. Outlook: The Next Twenty Years

    Energy Technology Data Exchange (ETDEWEB)

    Murayama, Hitoshi

    2003-12-07

    I present an outlook for the next twenty years in particle physics. I start with the big questions in our field, broken down into four categories: horizontal, vertical, heaven, and hell. Then I discuss how we attack the bigquestions in each category during the next twenty years. I argue for a synergy between many different approaches taken in our field.

  5. Deformation quantization: Twenty years after

    International Nuclear Information System (INIS)

    Sternheimer, Daniel

    1998-01-01

    We first review the historical developments, both in physics and in mathematics, that preceded (and in some sense provided the background of) deformation quantization. Then we describe the birth of the latter theory and its evolution in the past twenty years, insisting on the main conceptual developments and keeping here as much as possible on the physical side. For the physical part the accent is put on its relations to, and relevance for, 'conventional' physics. For the mathematical part we concentrate on the questions of existence and equivalence, including most recent developments for general Poisson manifolds; we touch also noncommutative geometry and index theorems, and relations with group theory, including quantum groups. An extensive (though very incomplete) bibliography is appended and includes background mathematical literature

  6. The next twenty years - IAEA's role

    International Nuclear Information System (INIS)

    Tape, G.F.

    1977-01-01

    The twentieth anniversary of an institution is an appropriate time to look back and to ask what has been achieved. It is also an appropriate time to look ahead and to ask what should be the mission for the future. How can the strengths of the International Atomic Energy Agency (IAEA) be best utilized, what new opportunities should be seized upon, and what challenges should the IAEA be prepared to meet in the next twenty years? Forward planning is a very necessary activity in today's world. There are so many demands on national or institutional resources that careful analysis of options is necessary to establish priorities and ultimately to provide for implementation. But such planning must be done carefully with full appreciation for the validity and sensitivity of the input assumptions and data. Furthermore, today's plan, while setting goals and directions, cannot be so inflexible that it cannot be responsive to ever-changing political, economic and technical constraints or opportunities. Thus in looking ahead, the plan must contain provisions for flexibility to provide for further modifications in the light of ever-changing knowledge, attitudes, and world conditions. The experience of the past five years in the energy field, and especially in nuclear energy, underscores this need. In looking ahead for the next twenty years, we are attempting to describe the International Atomic Energy Agency and its role through the twentieth century. In doing so, we are automatically laying the base for the Agency's work going into the twenty-first century. In short, we are trying to visualize a programme that can serve the coming generation and, in doing so, creating a base from which the needs of the succeeding generation can be met. This is a large order and the crystal ball is less than clear. (author)

    This paper reviews the direct and indirect oil import costs and examines actions that can be taken to reduce future imports. We find that the USA could greatly reduce its oil imports during the next 20 years by increasing energy efficiency and accelerating the introduction of fuels derived from renewable energy sources, particularly in the transport sector.

    The author discusses the reactor accident of Chernobyl, the information on its consequences so contradictory in the former USSR countries, the status of the effects observed, the forecasting concerning the onset of cancers in the coming years among the populations that were exposed to radiations, the public opinion facing the pessimists. He concludes on the lessons which can be drawn from Chernobyl. (A.L.B.)

  9. Which Russia, twenty years later?

    Full Text Available Russia is proud of its position among the emerging powers, of the strength provided by its ample energetic resources and its nuclear potential with which it can influence the world and always be taken into account. Nevertheless, the perception within the country is that stagnation has become Russia’s dominant characteristic at present. The objective of this article is to explore how this situation came about, analysing the evolution of domestic processes in Russia during both of its most defining periods: Yeltsin and Putin’s leadership, since the ephemeral presidency of Medvedev proved to be basically a continuation of the latter. During the eight years of Boris Yeltsin’s tenure, the state of crisis, latent or open, developed into the way that political processes are carried out in Russia. With Putin’s arrival, however, stability and State control are imposed, against the backdrop of economic growth, and they become values in themselves, far from the democratic discourse of the first years.

    2002-01-01

    The first training simulator for nuclear power plant personnel in Germany was commissioned twenty-five years ago. The strategy of training by simulators was developed and pursued consistently and continuously in order to ensure sound training of nuclear power plant personnel. The present thirteen simulators cover a broad range of plants. A systematic training concept also helps to ensure a high level of competence and permanent qualification of plant personnel. The anniversary was marked by a festive event at which Erich K. Steiner read a paper on 'The Importance of Simulator Training', and Professor Dr. Adolf Birkhofer spoke about 'Nuclear Technology Education and Training'. (orig.)

    Garnett, J.L.

    1995-01-01

    Progress in UV/EB curing during the past twenty five years is briefly reviewed. During this time developments in unique polymer chemistry, novel equipment design and the introduction of relevant educational programmes has enabled radiation curing to become an established technology with specific strengths in certain industries. Possible reasons for the emergence of the technology in these niche markets are discussed. Despite the worldwide recession, radiation curing is shown to be expanding at 5% per annum with the prospect of higher growth with improving economic conditions. (Author)

    1993-01-01

    Between 1964 and 1968, the liberal Catholic press had prepared the laity for the change expected to occur after the release of Pope Paul VI's encyclical "Humanae Vitae," but almost no one read it when it was released in July 1968. The media gave the impression that no one agreed with the Pope. The Archbishop of Baltimore denounced his dissenting priests. The media publicized the discord, resulting in his fellow bishops not supporting him or the Pope. Sound theology was limited then. Today many Catholic leaders and scholars openly defend the encyclical, e.g., since 1978, Pope John Paul II has supported the doctrine of marital noncontraception. Pope Pius XII called for every woman to breast feed. The 1969 publication of the Breastfeeding and Natural Child Spacing was the catalyst for 10 years of research which confirmed breast feeding's contraceptive effect. Family planning specialists and demographers agreed in the Bellagio Consensus in 1988 that mothers who practiced exclusive breast feeding and were amenorrheic need not use a contraceptive for the first 6 months postpartum. Recent research shows that this rule depends on the population, e.g., women in Bangladesh meeting the criteria do not need to use contraceptives for 1 year. Few natural family planning groups existed in 1968 (e.g., 1 diocese), but today there are natural family planning teachers in 49 US states and in 13 countries. Some Catholics are calling for couples wanting to marry to take a course in natural family planning. The media widely publicized the new unnatural family planning methods, especially the pill. Recently a baby magazine allocated natural family planning 2/3rd of a page. A reporter for the "Washington Post" plans to interview a Catholic leader about natural family planning, completely on his/her own initiative.

  15. Twenty five years of fundamental theory

    International Nuclear Information System (INIS)

    Bell, J.S.

    1980-01-01

    In reviewing the last twenty five years in fundamental physics theory it is stated that there has been no revolution in this field. In the absence of gravitation, Lorentz invariance remains a requirement on fundamental laws. Einstein's theory of gravitation inspires increasing conviction on the astronomical scale. Quantum theory remains the framework for all serious effort in microphysics, and quantum electrodynamics remains the model of a fully articulated microphysical theory, completely successful in its domain. However,a number of ideas have appeared, of great theoretical interest and some phenomenological success, which may well contribute to the next decisive step. Recent work on the following topics is mentioned; gravitational radiation, singularites, black body radiation from black holes, gauge and hidden symmetry in quantum electrodynamics, the renormalization of electromagnetic and weak interaction theory, non-Abelian gauge theories, magnetic monopoles as the most striking example of solitons, and supersymmetry.

  16. Twenty years after the Chernobyl accident

    International Nuclear Information System (INIS)

    2006-01-01

    Full text: The April 1986 accident at the Chernobyl nuclear power plant remains a painful memory in the lives of the hundreds of thousands of people who were most affected by the accident. In addition to the emergency rescue workers who died, thousands of children contracted thyroid cancer, and thousands of other individuals will eventually die of other cancers caused by the release of radiation. Vast areas of cropland, forests, rivers and urban centres were contaminated by environmental fallout. Hundreds of thousands of people were evacuated from these affected areas - forced to leave behind their homes, possessions, and livelihoods - and resettled elsewhere, in a traumatic outcome that has had long-lasting psychological and social impacts. The commemoration of the Chernobyl tragedy is taking place in many forums this month - in Minsk, in Kiev and in other locations. At the IAEA, it might be said that we have been responding to the accident and its consequences for twenty years, in a number of ways: first, through a variety of programmes designed to help mitigate the environmental and health consequences of the accident; second, by analyzing the lessons of what went wrong to allow such an accident to occur at all; and third, by working to prevent any such accident from occurring in the future. Building a strong and effective global nuclear safety regime is a central objective of our work. This requires effective international cooperation. The explosions that destroyed the Unit 4 reactor core, and discharged its contents in a cloud of radionuclides, made painfully clear that the safety risks associated with nuclear and radiological activities extend beyond national borders. International cooperation on nuclear safety matters - sharing information, setting clear safety standards, assisting with safety upgrades, and reviewing operational performance - has therefore become a hallmark of IAEA activity, particularly at a time when we are witnessing an expansion of

    2012-12-01

    There have been few studies of patients with renal allografts functioning for more than 20 years. We sought to identify clinical factors associated with ultra long-term (>20 year) renal allograft survival and to describe the clinical features of these patients. We performed a retrospective analysis of the Irish Renal Transplant Database and included 1174 transplants in 1002 patients. There were 255 (21.74%) patients with graft function for 20 years or more. Multivariate analysis identified recipient age (HR 1.01, CI 1.01-1.02), gender (male HR 1.25, CI 1.08-1.45), acute rejection (HR 1.26, CI 1.09-1.45) and transplant type (living related donor vs. deceased donor) (HR 0.52, CI 0.40-0.66) as significantly associated with long-term graft loss. Median serum creatinine was 115 μmol\\/L. The 5-year graft survival in 20-year survivors was 74.7%. The mean age at death was 62.7 years (±10.6). The most common causes of death were cardiovascular disease and malignancy. The two major causes of graft loss were death (with function) and interstitial fibrosis\\/tubular atrophy. Comorbidities included skin cancer (36.1%), coronary heart disease (17.3%) and other malignancies (14.5%). This study identifies factors associated with long-term allograft survival and a high rate of morbidity and early mortality in long-term transplant recipients.

    2004-09-01

    The development of radiation processing in Croatia is described from its inception 20 years ago up to the present time. Annual throughputs of treated materials are given by the categories of materials and pertaining volumes. The pasteurization of hard gelatine capsules occured during the early stages, while sterilization of disposable medical supplies has been dominant in the later stages. Irradiation of foods and of cosmetics and toiletries has been a minor fraction of the total throughput. Since the recovery of everyday life and economy of the country after the war, the total throughput has increased steadily to reach 13,000 m 3 kGy in 2002, 90% of which are medical supplies. Estimates of the present maximum capacity of 30,000 m 3 kGy and of future needs indicate that the present rate of growth could be sustained for the next several years only, unless a major upgrading is undertaken. An estimate of potential future needs is made.

  3. Cryogenic air separation: the last twenty years

    International Nuclear Information System (INIS)

    Grenier, M.; Petit, P.

    1986-01-01

    In the last 20 years cryogenic air separation plant sizes have increased from 150 tons per day to 2800 tons per day. Progressively reversing heat exchangers have replaced regenerators. However, with this arrangement, the quantity of pure product output is limited to about 50% of the air input. With the appearance on the market of molecular sieve, another arrangement was developed, which allows one to produce a combined pure product flow equivalent to 85% of the air input. Recently, there has been a strong tendency for the reversing exchangers to be superseded by this arrangement. Due to the ever increasing cost of energy, optimization studies are today pushed much further than they used to be; as a consequence there have been major changes in the size of equipment, improvements in the machinery, and simultaneous developments in instrumentation

  4. Twenty years of immunocontraceptive research: lessons learned.

    Science.gov (United States)

    Miller, Lowell A; Fagerstone, Kathleen A; Eckery, Douglas C

    2013-12-01

    The National Wildlife Research Center (NWRC) began immunocontraception vaccine research by testing porcine zona pellucida (PZP) on white-tailed deer (Odocoileus virginianus). Early PZP research demonstrated that PZP induced infertility; however, increased length of the rut was observed in PZP-treated deer. An alternative vaccine using a keyhole limpet hemocyanin-gonadotropin-releasing hormone (KLH-GnRH) conjugate formulated with modified Freund's adjuvant was developed at NWRC. Suppression of GnRH has reduced reproduction in both sexes but is most effective in females. This vaccine was effective in preventing contraception in female deer for several years after a prime and boost. Due to adverse side effects of Freund's adjuvant, NWRC developed a new adjuvant called AdjuVac, a mineral oil/surfactant adjuvant with the addition of Mycobacterium avium as an immunostimulant. The price of KLH prompted a search for a more economical hemocyanin carrier protein for the GnRH peptide. Blue protein, derived from the mollusk Concholepas concholepas, proved to be a successful option. Formulation improvements resulted in a vaccine that can be effective as a single injection for multiple years, now called GonaCon. GonaCon is registered with the Environmental Protection Agency (EPA) for use in white-tailed deer in urban/suburban areas and for wild horses (Equus caballus) and burros (Equus asinus). Future GonaCon applications may include reducing reproduction to manage populations of other wildlife species, such as prairie dogs (Cynomys ludovicianus) in urban areas and suppressing reproduction to reduce the spread of venereal diseases such as brucellosis. Research is being conducted to develop a GnRH vaccine used in combination with the rabies vaccine to control population growth in free-roaming dogs, with the secondary effect of managing the spread of rabies. The EPA would regulate all these uses. Research is also ongoing on a GnRH vaccine to delay the onset of adrenocortical

  5. Paleolithic nutrition: twenty-five years later.

    Science.gov (United States)

    Konner, Melvin; Eaton, S Boyd

    2010-12-01

    A quarter century has passed since the first publication of the evolutionary discordance hypothesis, according to which departures from the nutrition and activity patterns of our hunter-gatherer ancestors have contributed greatly and in specifically definable ways to the endemic chronic diseases of modern civilization. Refinements of the model have changed it in some respects, but anthropological evidence continues to indicate that ancestral human diets prevalent during our evolution were characterized by much lower levels of refined carbohydrates and sodium, much higher levels of fiber and protein, and comparable levels of fat (primarily unsaturated fat) and cholesterol. Physical activity levels were also much higher than current levels, resulting in higher energy throughput. We said at the outset that such evidence could only suggest testable hypotheses and that recommendations must ultimately rest on more conventional epidemiological, clinical, and laboratory studies. Such studies have multiplied and have supported many aspects of our model, to the extent that in some respects, official recommendations today have targets closer to those prevalent among hunter-gatherers than did comparable recommendations 25 years ago. Furthermore, doubts have been raised about the necessity for very low levels of protein, fat, and cholesterol intake common in official recommendations. Most impressively, randomized controlled trials have begun to confirm the value of hunter-gatherer diets in some high-risk groups, even as compared with routinely recommended diets. Much more research needs to be done, but the past quarter century has proven the interest and heuristic value, if not yet the ultimate validity, of the model.

  6. [The Gulf War Syndrome twenty years on].

    Auxéméry, Y

    2013-10-01

    After Operation Desert Storm which took place in Iraq from August 1990 to July 1991 involving a coalition of 35 countries and a 700,000 strong contingent of mainly American men, some associations of war veterans, the media and researchers described a new diagnostic entity: the Gulf War Syndrome (GWS). GWS seems to be a new disorder which associates a litany of functional symptoms integrating the musculoskeletal, digestive, tegumentary and neurosensory systems. The symptoms presented do not allow a syndrome already known to be considered and the aetiology of the clinical picture remains unexplained, an increasing cause for concern resulting from the extent of the phenomenon and its media coverage. It quickly appears that there is no consensus amongst the scientific community concerning a nosographic description of GWS: where can all these functional complaints arise from? Different aetiopathogenic hypotheses have been studied by the American administration who is attempting to incriminate exposure to multiple risks such as vaccines and their adjuvants, organophosphorous compounds, pyridostigmine (given to the troops for the preventive treatment of the former), impoverished uranium, and the toxic emanations from oil well fires. But despite extremely in-depth scientific investigations, 10 years after the end of the war, no objective marker of physical suffering has been retained to account for the disorders presented. It would appear that the former soldiers are in even better objective health than the civil population whereas their subjective level of health remains low. Within this symptomatic population, some authors have begun to notice that the psychological disorders appear and persist associating: asthenia, fatigability, mood decline, sleep disorders, cognitive disorders and post-traumatic stress disorder (PTSD). Within the nosological framework, does GWS cause functional disorders or somatisation? Finally, 20 years after the end of the fighting, only PTSD has

    Developments in the area of clustering aspects of nuclear structure and reactions over the past twenty-five years are reviewed. The viewpoint is that the nucleus is an assembly of clusters. The question is whether clusters actually exist in the nucleus. Although there is abundant evidence for this in light nuclei, the situation for more complex clusters in heavier nuclei is much worse. Differential cross sections for scattering of alpha particles and heavy ions are shown

    The Russian RERTR Program started approximately 20 years ago. The USSR always supported principles and goals of the policy of nonproliferation and at the end of 70's the Soviet Government decided to create such national program. Twenty years is the sufficient time to estimate preliminary results of the realization of the program and its prospects on the future. After the first successes of the program, when the enrichment of uranium in fuel elements for foreign supplies was reduced from 80 % to 36 %, the realization of the program was suspended in connection with financial difficulties. But in the beginning of the 90's the Program has received a new pulse connected to the inclusion of Russian scientists and engineers in the international Program. Now basic directions in development of new kinds of fuel are development of works on fuel on a basis dioxide of uranium and development of fuel on a basis of U-Mo alloy. In the future to basic goals of the program the problem of the management of the spent nuclear fuel should be added. The management of HEU at the final stage of a fuel cycle becomes an important objective of the program, since the basic amount of HEU is concentrated in storage of SNF. (author)

  17. Twenty years of operation of Ljubljana's TRIGA Mark II reactor

    International Nuclear Information System (INIS)

    Dimic, V.

    1986-01-01

    Twenty years have now passed since the start of the TRIGA Mark II reactor in Ljubljana. The reactor was critical on May 31, 1966. The total energy produced until the end of May 1986 was 14.048 MWh or 585 MWd. For the first 14 years (until 1981) the yearly energy produced was about 600 MWh, since 1981 the yearly energy produced was 1000 MWh when a routine radioactive isotopes production started for medical use as well as other industrial applications, such as doping and irradiation with fast neutrons of silicon monocrystals, production of level indicators (irradiated cobalt wire), production of radioactive iridium for gamma-radiography, leak detection in pipes by sodium, etc. Besides these, applied research around the reactor is being conducted in the following main fields, where- many unique methods have been developed or have found their way into the local industry or hospitals: neutron radiography, neutron induced auto-radiography using solid state nuclear track detectors, nondestructive methods for assessment of nuclear burn-up, neutron dosimetry, calculation of core burn-up for the optimal in-core fuel management strategy. The solvent extraction method was developed for the everyday production of 99m Tc, which is the most widely used radionuclide in diagnostic nuclear medicine. The methods were developed for the production of the following isotopes: 18 F, 85m Kr, 24 Na, 82 Br, 64 Zn, 125 I. Neutron activation analysis represents one of the major usages for the TRIGA reactor. Basic research is being conducted in the following main fields: solid state physics (elastic and inelastic scattering of the neutrons), neutron dosimetry, neutron radiography, reactor physics and neutron activation analysis. The reactor is used very extensively as a main instrument in the Reactor Training Centre in Ljubljana where manpower training for our nuclear power plant and other organisations has been performed. Although the reactor was designed very carefully in order to be used for

  18. Twenty years on: Poverty and hardship in urban Fiji

    Directory of Open Access Journals (Sweden)

    Jenny Bryant-Tokalau

    2012-09-01

    Full Text Available Through ‘official statistics’, academic and donor interpretations as well as the eyes of Suva residents, this paper presents an overview and case study of twenty years of growing poverty and hardship in the contemporary Pacific. Focusing on the past two decades, the paper notes how much, and yet so little, has changed for those attempting to make a living in the rapidly developing towns and cities. Changing interpretations of poverty and hardship are presented, moving from the ‘no such thing’ view, to simplification, and finally to an understanding that Pacific island countries, especially Fiji, are no longer an ‘extension’ of Australia and New Zealand, but independent nations actively trying to find solutions to their issues of economic, social and political hardship whilst facing challenges to traditional institutions and networks. Fiji is in some respects a very particular case as almost half of the population has limited access to secure land, but the very nature of that vulnerability to hardship and poverty holds useful lessons for wider analysis.

    This article aims to provide a framework for analysing social opposition In Italy against the construction and management of electric power plants (nuclear and thermoelectric) and big electricity power lines in the past twenty years. First The author provide a history of social environmental opposition in the electric sector. This is followed by a typology of reason for opposition in terms of risk perception, which has been applied to about forty cases of social opposition against electric plants. This study an original experimental methodology which could also yield useful results when applied to other complex social phenomena. In the third phase of the study the author analyse the various roles of the social and institutional actors involved in the opposition, and the obstacles to future consensus building. The most interesting result of the study is the not only social but political nature opposition. This factor necessitates integration of the traditional individual risk perception approach with an approach which analyses political and social action of NGO's

  20. The deep, hot biosphere: Twenty-five years of retrospection.

    2017-07-03

    Twenty-five years ago this month, Thomas Gold published a seminal manuscript suggesting the presence of a "deep, hot biosphere" in the Earth's crust. Since this publication, a considerable amount of attention has been given to the study of deep biospheres, their role in geochemical cycles, and their potential to inform on the origin of life and its potential outside of Earth. Overwhelming evidence now supports the presence of a deep biosphere ubiquitously distributed on Earth in both terrestrial and marine settings. Furthermore, it has become apparent that much of this life is dependent on lithogenically sourced high-energy compounds to sustain productivity. A vast diversity of uncultivated microorganisms has been detected in subsurface environments, and we show that H 2 , CH 4 , and CO feature prominently in many of their predicted metabolisms. Despite 25 years of intense study, key questions remain on life in the deep subsurface, including whether it is endemic and the extent of its involvement in the anaerobic formation and degradation of hydrocarbons. Emergent data from cultivation and next-generation sequencing approaches continue to provide promising new hints to answer these questions. As Gold suggested, and as has become increasingly evident, to better understand the subsurface is critical to further understanding the Earth, life, the evolution of life, and the potential for life elsewhere. To this end, we suggest the need to develop a robust network of interdisciplinary scientists and accessible field sites for long-term monitoring of the Earth's subsurface in the form of a deep subsurface microbiome initiative.

  1. Twenty years of ABACC: Accomplishments, lessons learnt and future perspectives

    From the inception of the implementation of the Quadripartite Agreement (INFCIRC/435), in 1991, ABACC has had an important role at the non-proliferation agenda and has also been an active player in the international safeguards. It was necessary for ABACC to develop a technical capacity to face the challenges to be a safeguards agency and to gain credibility in the nuclear safeguards world. This capacity means to develop and implement safeguards systems in the technical area, in the inspection framework, in the conceptual analysis of processes and approaches and in the political scenario. These tasks conducted the strategic plan of ABACC on the last 20 years. Among the accomplishments, ABACC has been involved in the application of safeguards to sensitive and complex installations, in developing safeguards instrumentation, in establishing a technical and trained inspectorate, in constructing a cooperative and coordinate environment with IAEA for safeguards application. Other challenges as R and D of equipment and quality assurance systems were also managed during all these years. ESARDA is one forum that ABACC is involved and always shares experience and ideas. On July 18th, 2011 ABACC will formally complete 20 years. This paper summarizes the accomplishments, lessons learnt and future actions for strengthen the ABACC safeguards role. It also addresses the collaboration of ABACC with other organizations in the non-proliferation and international safeguards arena.

  2. Understanding Contamination; Twenty Years of Simulating Radiological Contamination

    Energy Technology Data Exchange (ETDEWEB)

    2012-02-01

    A wide variety of simulated contamination methods have been developed by researchers to reproducibly test radiological decontamination methods. Some twenty years ago a method of non-radioactive contamination simulation was proposed at the Idaho National Laboratory (INL) that mimicked the character of radioactive cesium and zirconium contamination on stainless steel. It involved baking the contamination into the surface of the stainless steel in order to 'fix' it into a tenacious, tightly bound oxide layer. This type of contamination was particularly applicable to nuclear processing facilities (and nuclear reactors) where oxide growth and exchange of radioactive materials within the oxide layer became the predominant model for material/contaminant interaction. Additional simulation methods and their empirically derived basis (from a nuclear fuel reprocessing facility) are discussed. In the last ten years the INL, working with the Defense Advanced Research Projects Agency (DARPA) and the National Homeland Security Research Center (NHSRC), has continued to develop contamination simulation methodologies. The most notable of these newer methodologies was developed to compare the efficacy of different decontamination technologies against radiological dispersal device (RDD, 'dirty bomb') type of contamination. There are many different scenarios for how RDD contamination may be spread, but the most commonly used one at the INL involves the dispersal of an aqueous solution containing radioactive Cs-137. This method was chosen during the DARPA projects and has continued through the NHSRC series of decontamination trials and also gives a tenacious 'fixed' contamination. Much has been learned about the interaction of cesium contamination with building materials, particularly concrete, throughout these tests. The effects of porosity, cation-exchange capacity of the material and the amount of dirt and debris on the surface are very important factors

  4. Cost in medical education: one hundred and twenty years ago.

    Science.gov (United States)

    Walsh, Kieran

    2015-10-01

    The first full paper that is dedicated to cost in medical education appears in the BMJ in 1893. This paper "The cost of a medical education" outlines the likely costs associated with undergraduate education at the end of the nineteenth century, and offers guidance to the student on how to make financial planning. Many lessons can be gleaned from the paper about the cost and other aspects of nineteenth century medical education. Cost is viewed almost exclusively from the domain of the male gender. Cost is viewed not just from the perspective of a young man but of a young gentleman. There is a strong implication that medicine is a club and that you have to have money to join the club and then to take part in the club's activities. Cost affects choice of medical school and selection into schools. The paper places great emphasis on the importance of passing exams at their first sitting and progressing through each year in a timely manner-mainly to save costs. The subject of cost is viewed from the perspective of the payer-at this time students and their families. The paper encourages the reader to reflect on what has and has not changed in this field since 1893. Modern medical education is still expensive; its expense deters students; and we have only started to think about how to control costs or how to ensure value. Too much of the cost of medical education continues to burden students and their families.

    Over the past 25 years, the incidence of newborns with congenital defects in Spain has fallen by 56.7% primarily due to the practice of "fetal risk" abortion, after prenatal diagnosis. In some cases, such as people with Down syndrome, the strategy involves the removal of 80-90% of those affected in pregnancy. After presenting the techniques used today and statistical data, we will make a reflection about the ethical justification for prenatal diagnosis programs and practice of "eugenic" abortion.

  1. Isar-2 nuclear power station twenty-five years

    Fischer, Erwin; Luginger, Markus

    2013-01-01

    The Isar-2 nuclear power station (KKI 2) began commercial power operation on April 9, 1988. In these past 25 years the plant generated a total of approx. 285 billion kWh of electricity. The annual electricity production of KKI 2 of approx. 12 billion kWh corresponds to a share of approx. 15 % in the cumulated Bavarian electricity production. This amount of electricity, theoretically, could supply some 3 million three person households, or meet two thirds of the electricity requirement of the Bavarian industry, for one year. In its 25 years of power operation the Isar-2 nuclear power plant has recorded the highest annual gross electricity production of all nuclear power plants in the world nine times so far. A plant performance as impressive as this necessitates a plant availability far above the average. This, in turn, is based on short revision times and faultfree plant operation. However, high plant safety and availability must not be taken for granted, but are the result of responsible, safety-minded plant operation combined with continuous plant optimization and permanent execution of comprehensive checks, inspections, and maintenance measures. Besides plant technology also organization and administration were permanently advanced and adapted to changing requirements so as to safeguard reliable, safe, and non-polluting plant operation.

    1998-12-31

    Archaeological investigations on a range of sites in the Pacific Region identified four well separated obsidian flows which varied in terms of their spatial scale, ease of extraction of raw material, and quality of obsidian for artefact manufacture. Extensive deposits of the by-products from quarrying and artefact manufacture were associated with each flow. Using enhancements in PIXE-PIGME, a finer discrimination was achieved that has allowed each artefact to be assigned to one of the four sub-regions in the Willaumez Peninsular group. These results have led to a better understanding of ancient trade practices. Further analyses of archaeological materials from multiple sites in the Bismarck Archipelago have shown: 1. During the Pleistocene (20,000 - 10,000 years ago) obsidian from both major source regions was repeatedly moved to New Ireland, a distance of some 600 km. The Mopir source predominated. 2. In the period 3500-1500 years ago Mopir was very rare probably because the source was cut off due to a massive volcanic eruption. 3. Although proximity to outcrop is usually the major factor in determining which obsidian was used, one excellent sub-source, Baki on Garua Island, was almost never traded and was not always even the preferred source locally

    Climate change and the urgency of decarbonizing the built environment are driving technological innovation in the way we deliver thermal comfort to occupants. These changes, in turn, seem to be setting the directions for contemporary thermal comfort research. This article presents a literature review of major changes, developments, and trends in the field of thermal comfort research over the last 20 years. One of the main paradigm shift was the fundamental conceptual reorientation that has taken place in thermal comfort thinking over the last 20 years; a shift away from the physically based determinism of Fanger's comfort model toward the mainstream and acceptance of the adaptive comfort model. Another noticeable shift has been from the undesirable toward the desirable qualities of air movement. Additionally, sophisticated models covering the physics and physiology of the human body were developed, driven by the continuous challenge to model thermal comfort at the same anatomical resolution and to combine these localized signals into a coherent, global thermal perception. Finally, the demand for ever increasing building energy efficiency is pushing technological innovation in the way we deliver comfortable indoor environments. These trends, in turn, continue setting the directions for contemporary thermal comfort research for the next decades. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    It is twenty years this year since the first unit WWER 440 of Slovak Nuclear Power Plant Jaslovske Bohunice was commissioned. There are four units WWER 440 in operation Jaslovske Bohunice site. First two units of older soviet PWR design V-230 (also known as V-1) and other two units of newer V-213 type (also known as V-2). The goal of this presentation is to summarize and evaluate the operation of Unit 1 and 2 for this period of time and mainly to describe what has been done and what is planned to be done to increase the nuclear safety and operational reliability of both units. The operating organization and regulatory authority assume that an internationally acceptable level of safety will be reached by accomplishing of the upgrading program.(author)

    After 20 years of sometimes quiet growth, fragment-based drug discovery (FBDD) has become mainstream. More than 30 drug candidates derived from fragments have entered the clinic, with two approved and several more in advanced trials. FBDD has been widely applied in both academia and industry, as evidenced by the large number of papers from universities, non-profit research institutions, biotechnology companies and pharmaceutical companies. Moreover, FBDD draws on a diverse range of disciplines, from biochemistry and biophysics to computational and medicinal chemistry. As the promise of FBDD strategies becomes increasingly realized, now is an opportune time to draw lessons and point the way to the future. This Review briefly discusses how to design fragment libraries, how to select screening techniques and how to make the most of information gleaned from them. It also shows how concepts from FBDD have permeated and enhanced drug discovery efforts.

    1998-03-01

    This report provides a brief overview on the contribution of some CSNI International Standard Problems (ISPs) to nuclear reactor safety issues (41 ISPs performed over the last 22 years). This CSNI activity on ISPs has been one of the major activities of the Principal Working Group no.2 on Coolant System Behaviour. Its domain extended from thermal-hydraulics to several other accident domains following the main concerns of nuclear reactor safety, e.g., LOCA predictions fuel behaviour, operator procedures, containment thermal-hydraulics severe accidents, VVERs, etc. ISPs are providing unique material and benefits for some safety related issues. Clearly, all the technical findings and benefits provided by ISPs are still needed and contribute to advancement of nuclear safety. The report provides some overview on the general objectives of ISPs, content and types of ISPs, and technical domains covered by ISPs, followed by a synthesis of technical findings and benefits to the scientific community

    In Hungary, radiation protection training for radiation workers has been introduced in very early, just following the publication of the ICRP recommendation No. 26. Before that, in some of the institutions, radiation protection training was recommended for technicians and medical doctors working in nuclear medicine, X-ray diagnostic radiology and radiation therapy, as well as in some of industrial applications, but not on regular way. Since 1988, radiation protection training regulated by the Ministry of Health and required for all of the workers in radiation workplaces licensed by the authority the State Public Health and Medical Officers Service (SPHAMOS). Decree No. 16/2000. (VI. 8.) EuM of the Minister of Health on the enforcement of Clauses of the Nuclear Law 116/1996 regulates the radiation protection training of Radiation Workers (RW). Annex 4 of Decree sees radiation protection training and in-service training: Persons performing conducted work in the field of the use of the nuclear energy and any other work within legal relationship shall be educated in training and in-service training at an interval of 5 years. Three levels of the training introduced; basic, extended and comprehensive, based on radiation risk related to the given job. Several institutions are involved in performing radiation protection training, such universities, scientific institutions, Regional Radiological Health Centers (RRHC) of SPHAMOS, private enterprises etc. All training course material is subject to accreditation. Most of the faculties of the universities involved in training of natural sciences and engineering provide subjects on the fundamentals of dosimetry, radiobiology and radiation protection within the courses of physics, biophysics, chemistry, biology, ecology etc. These courses take 5-10 contact hours per week on average. The members of the Hungarian Committee of EUTERP Platform summarize their broad experience collected in the past 20 year. (author)

    Easy access to communication and information technologies has increased our dependence on technology for various aspects of our lives. Nevertheless, this remarkable growth of Internet Usage has been inextricably paired with a rise of excessive and dysfunctional Internet use. Conceptualized around 1996, a few years after the inception of the World Wide Web, Internet addiction has developed into a global issue influencing varying segments of the population at different levels. Despite heated debates on its addictive nature, consensus is emerging regarding the existence of this problematic behavior. In this paper we provide a comprehensive overview of the literature on Internet addiction in last 20 years. Purpose of this paper is to present crucial findings on Internet addiction to health profession. Besides numerous benefits of Internet use, the virtual environment brings various risks in every age group. The Internet is very significant in the everyday activities of children and youth and professional interventions with this age group should be specific considering their developmental characteristics. Exposure to online risks can have long-lasting and intense negative effects. Effective programs in prevention and treatment should include a multi-sectoral and interdisciplinary approach. Detail review of the symptomatology, diagnosis model an possibilities of treatment can be multiple beneficial to the health professionals and other helping professions due to actual needs for interventions in the field of the internet addiction treatment. Internet addiction is slowly becoming a societal concern as it particularly affects adolescents and children, who are more exposed and consequently more vulnerable. Findings presented in the paper can benefit in practice of treatment internet addiction and also as framework for further researches in the field.

    To describe disease progression and treatment outcomes over a 20-year period (ages 5-25) in a young man with Norrie disease (occuloacousticocerebral dysplasia), ND; OMIM #310600. Affected individuals are born blind and develop progressive sensory loss with onset in adolescence. This disease is X-linked and has been associated with mutations of the NDP gene (Xp11.4). The patient was followed using repeated audiograms, as well as reports of educational progress and hearing aid use. The specific mutation was found by molecular analysis. The patient demonstrated progressive sensory loss with good preservation of word recognition. The loss was initially high frequency and asymmetric in adolescence and became more severe, more symmetric and affected practically all frequencies by the end of childhood. Educational progress was affected by the cognitive effects of the syndrome, and hearing aid use was very effective. A bilateral progressive sensory loss with good preservation of word recognition was documented in detail. The residual word recognition supported good use of hearing aids in this case.

    The Technical Support Organization was established by the Atomic Energy Commission in January 1968 at Brookhaven National Laboratory (BNL). The original idea came from a small group of scientists at BNL. The group included Willy Higinbotham, Herb Kouts, Frank Miles, Richard Dodson, and Gerhardt Friedlander. The AEC endorsed the idea of a technical support group to provide technical assistance to AEC's Office of Safeguards and Materials Management and they sent requests for expressions of interest throughout the complex. For a number of reasons, to be discussed in the paper, the Technical Support Organization was established at BNL. An early project was the Conceptual Design for Safeguarding Nuclear Material which formed the first logical and systematic description of the integration of several elements into a safeguards system for protecting nuclear materials. Many other projects were undertaken over the years. TSO today provides technical assistance to the DOE Office of Safeguards and Secuirty, the Office of Classification and Technology Policy, and the Office of Security Evaluations. Technical support to the IAEA is provided under the Program of Technical Assistance to Agency Safeguards (POTAS). Recently, TSO began a program of technical assistance to the Air Force Weapons Laboratory in the area of nuclear systems security

    Women in Neuroscience (WIN) is an international organization whose major goal is to promote the professional advancement of women neuroscientists. To this end, WIN facilitates contacts and communication among women working in neuroscience, and organizes appropriate activities at the annual Society for Neuroscience (SfN) meeting. WIN was created in 1980, when despite major changes and advances in 'equal opportunities', women were still not achieving a proportionate level of success in the subdiscipline of neurosciences. In 1980, women made up 40 to 50% of entering classes in medical schools or graduate programs, but often comprised only 5 to 15% of leadership in respective organizations. Although there had been women elected to serve as SfN presidents, council, and committee members, women were under-represented in other positions of the Society, such as symposium and session chairs. There was an even lesser degree of representation in leadership positions at universities and medical schools in terms of full professorships, chairs, and program directors, as well as on editorial boards, advisory boards, and councils. Over the years, WIN has worked with success toward increasing the participation of women in neuroscience.

    There is little left to be said about abortion in the US; most Americans are either bored with the issue or the issue has simply lost its immediacy. The world today is certainly different from the 1970s, when the US Supreme Court issued its Roe vs. Wade decision. That era was marked by societal and economic generosity manifest by greater acceptance of civil rights, liberal sexual mores, acceptance of divorce, ignorance of infertility, and a focus on alleviating the readily apparent suffering of women made desperate by an unwanted pregnancy. In the 25 intervening years, abortion has remained legal even as the US has become more conservative. It may be, therefore, that pro-choices forces are safe enough to attempt to regain the moral edge and lead the way out of the abortion wars. In order to do this, the values that informed early commitment to women's right to make the abortion decision must finally be clearly expressed, explained, and advocated. Also, pro-choice groups must initiate a more meaningful public dialogue about the morality of abortion and offer answers to the hard questions such as whether it is not better to encourage teenagers to talk to their parents about an unwanted pregnancy, what is the moral significance of developing life, is viability a significant threshold, are there better and worse reasons for abortion, and are some pro-abortion arguments morally dubious. While some may consider this course of action threatening, the visionary leadership that is desperately needed involves addressing both the underlying values and hard questions.

  16. Twenty Years of Research on Cytokine-Induced Sickness Behavior*

    2007-01-01

    Cytokine-induced sickness behavior was recognized within a few years of the cloning and expression of interferon-α, IL-1 and IL-2, which occurred around the time that the first issue of Brain, Behavior, and Immunity was published in 1987. Phase I clinical trials established that injection of recombinant cytokines into cancer patients led to a variety of psychological disturbances. It was subsequently shown that physiological concentrations of proinflammatory cytokines that occur after infection act in the brain to induce common symptoms of sickness, such as loss of appetite, sleepiness, withdrawal from normal social activities, fever, aching joints and fatigue. This syndrome was defined as sickness behavior and is now recognized to be part of a motivational system that reorganizes the organism's priorities to facilitate recovery from the infection. Cytokines convey to the brain that an infection has occurred in the periphery, and this action of cytokines can occur via the traditional endocrine route via the blood or by direct neural transmission via the afferent vagus nerve. The finding that sickness behavior occurs in all mammals and birds indicates that communication between the immune system and brain has been evolutionarily conserved and forms an important physiological adaptive response that favors survival of the organism during infections. The fact that cytokines act in the brain to induce physiological adaptations that promote survival has led to the hypothesis that inappropriate, prolonged activation of the innate immune system may be involved in a number of pathological disturbances in the brain, ranging from Alzheimers' disease to stroke. Conversely, the newly-defined role of cytokines in a wide variety of systemic co-morbid conditions, ranging from chronic heart failure to obesity, may begin to explain changes in the mental state of these subjects. Indeed, the newest findings of cytokine actions in the brain offer some of the first clues about the

    This paper provides a review of the dose assessment of discharges to air of two industries processing NORM (Naturally Occurring Radioactive Materials) in the Netherlands. An industrial plant producing elemental phosphorus (thermal process, unique within Europe) reports since 1987 its emission data to the Dutch Ministry of the Environment (VROM: Ministry of Housing, Spatial Planning and the Environment). This plant accounts for the highest release of Po-210 to air in the Netherlands, with a yearly average of approximately 500 GBq. Other significant NORM discharges to air arise from an industrial plant with blast-furnaces for steel production. Yearly discharges fall under permit, and are reported, since 1993. RIVM, the National Institute for Public Health and the Environment, is tasked by the Ministry to assess the dose to the general public arising from these discharges to air. Air transport modelling is used to determine both air concentration (for inhalation exposure) and deposition rate of the radionuclides. A (conservative) committed ingestion dose is determined by modelling the uptake of radionuclides from contaminated farmland, and assuming a food basket to be fairly representative for the population of the Netherlands. Discharges to water in the Netherlands have decreased in the past twenty years, due both to the closure of two phosphoric acid plants a decade ago and the improved treatment of waste fluids by other NORM industries. The collective dose assessed from discharges to air since 1987 is presented here. (author)

    The failure of central planning in the totalitarian systems of the USSR and its satellites adversely affected not only the economy and social relations but also the population health. While in the countries with established democracy (DEM) the general health and the life expectancy (LE) steadily improved, in countries declaring socialism (SOC) the LE was stagnant and in the USSR even decreased. Dramatic changes in Russia after the demise of Soviet Union resulted in an extraordinary destabilization of LE that reached a minimum in 1994. Remarkably, even twenty years after the breakdown of the Iron Curtain there persists a gap in the general health between the DEM and the SOC regions of Europe. Within the territory of the former Soviet influence there are additional differences in LE: Central Europe is much better off than Russia and its neighbours. Main cause of relatively high mortality in the post totalitarian Europe is the cardiovascular disease (CVD). Among females about 80% difference in LE between DEM and SOC countries is related to premature CVD mortality. In SOC males compared to DEM, about 50% of the higher mortality is caused by CVD, 20% is related to external factors (trauma, suicide) and 10% is oncologic disorders. The main suggested cause of such excess mortality, besides a low socioeconomic level and limited funding for health care, is an improper life style: alcoholism, smoking and inadequate intake of protective nutrients. Alcoholism, especially binge drinking is a prominent factor in Russia, Belarus, Ukraine and in the Baltic Republics (Fig. 6, Tab. 4, Ref. 20).

    The Defense TRU Waste Program (DTWP) is the focal point for the Department of Energy in national planning, integration, operation, and technical development for TRU waste management. The scope of this program extends from the point of TRU waste generation through delivery to a permanent repository. The TRU program maintains a close interface with repository development to ensure program compatibility and coordination. The defense TRU program does not directly address commercial activities that generate TRU waste. Instead, it is concerned with providing alternatives to manage existing and future defense TRU wastes. The FY 87 Program Plan is consistent with the Defense TRU Waste Program goals and objectives stated in the Defense Transuranic Waste Program Strategy Document, January 1984. The roles of participants, the responsibilities and authorities for Operations, and Research ampersand Development (R ampersand D), the organizational interfaces and communication channels for R ampersand D and the establishment of procedures for planning, reporting, and budgeting of Operations and R ampersand D activities meet requirements stated in the Technical Management Plan for the Transuranic Waste Management Program. Detailed budget planning (i.e., programmatic funding and capital equipment) is presented for FY 87; outyear budget projections are presented for future years

    The commercial service at Imperial College was maintained for twenty years by juggling staff, equipment and irradiation facilities, building when required and downsizing when necessary. At no point was the service entirely self-sufficient since staff had more than one role and participated in teaching and research as well as the analytical service. The balance was of benefit everyone concerned, including students who have studied with us and gained experience of working within a well maintained and quality assured laboratory. The benefits of collaborating with industry cannot be overestimated, with the secondary effects for research and teaching identified previously. A key change took place in the early 2000s, which can be seen in Figure 5 by the fall in income from 2002. The author’s academic department became a separate cost centre to the Reactor Centre, and irradiations were charged at a more realistic price. Once the true costs were built in, including space, overheads and irradiation charges, it was not possible to maintain a viable business plan without reducing staff to a non-viable number. As a result, in 2003 the analytical service was handed to the Reactor Centre, in which the business could remain viable because the irradiation charge became income not expenditure. Without the continued interactions that academic research generated, the NAA service has diminished with very few customers in the past few years. Staff are occupied with internal work for the reactor such as routine monitoring using gamma spectrometry. In summary the introduction and operation of a commercial service is to be recommended, particularly in those situations where it can complement other parts of the organisation such other analytical or academic activities. It is not practical to fund reactor operations entirely on commercial activities, but it can result in a number of spin-offs that can increase other income streams such as teaching and research projects.

    Lyczkowski, R.W.

    1999-01-01

    This presentation will cover some of the highlights of multiphase modeling in collaboration with Professor Dimitri Gidaspow (DG) over the last roughly twenty-five years. It all started in 1972 in Idaho Falls with Charles Solbrig, who planned and initiated a project for the former USAEC to develop a computer code to replace RELAP4 to analyze the loss of coolant accident (LOCA). DG spent his sabbatical on the project in 1973. One highlight was the discovery of complex characteristics, the implications of which are still pondered by some. Fluidization research began in 1978 when the author collaboratively developed a step-by-step building-block approach to understanding the hydrodynamics of fluidized beds, an approach closely coupled to validation experiments. A grant from the USDOE to study solids circulation around a jet in a fluidized bed was awarded to DG in 1978. Following that, grants from GRI, NSF, and a contract from Westinghouse Electric Corp. allowed the early work to continue. Progress was slow since computer costs were high. Subsequent continuing support from the USDOE, NSF, EPRI, and industry has allowed research to continue, as has his collaboration. A highlight of this collaboration was the development of the monolayer energy dissipation (MED) erosion model. Multiphase flow and fluidization theory took quantum leaps with the publication of DG's Multiphase Flow and Fluidization: Continuum and Kinetic Theory Descriptions (MFF), Academic Press, San Diego (1994), for which there is essentially no competition. Only the late Professor S.L. Soo's Particulates and Continuum: Multiphase Fluid Dynamics, Hemisphere Publishing Corp., New York (1989), a textbook version of the classic monograph Multiphase Fluid Dynamics, Science Press, Beijing, China (1990), comes close. In MFF, the kinetic theory of granular flow has evolved as a potentially viable adjunct to the continuum multiphase theory, of which fluidization is one important manifestation. It must be

    Obstructive sleep apnea (OSA) is a common disorder, and continuous airway positive pressure (CPAP) is considered to be the gold standard of therapy. CPAP however is known to have problems with adherence, with many patients eventually abandoning the device. The purpose of this paper is to assess secular trends in CPAP adherence over the long term to see if there have been meaningful improvements in adherence in light of the multiple interventions proposed to do so. A comprehensive systematic literature review was conducted using the Medline-Ovid, Embase, and Pubmed databases, searching for data regarding CPAP adherence over a twenty year timeframe (1994-2015). Data was assessed for quality and then extracted. The main outcome measure was reported CPAP non-adherence. Secondary outcomes included changes in CPAP non-adherence when comparing short versus long-term, and changes in terms of behavioral counseling. Eighty-two papers met study inclusion/exclusion criteria. The overall CPAP non-adherence rate based on a 7-h/night sleep time that was reported in studies conducted over the twenty year time frame was 34.1 %. There was no significant improvement over the time frame. Behavioral intervention improved adherence rates by ~1 h per night on average. The rate of CPAP adherence remains persistently low over twenty years worth of reported data. No clinically significant improvement in CPAP adherence was seen even in recent years despite efforts toward behavioral intervention and patient coaching. This low rate of adherence is problematic, and calls into question the concept of CPAP as gold-standard of therapy for OSA.

    The Canadian government recently announced approval of a five-year-plan for TRIUMF, giving the Vancouver Laboratory assured funding until the year 2000. Besides continuation of the multidisciplinary cyclotron, this will allow construction of ISAC-1, a new on-line isotope separator. At the same time, TRIUMF will also be responsible for Canadian ''in-kind'' contributions to international science at CERN's LHC proton-proton collider (see page 1). The federal plan strengthens TRIUMF's role as a national facility, run by a consortium of universities across Canada. In addition, TRIUMF will have even stronger international links. The federal government has allocated a total of $166.6 million to TRIUMF over the next five years. In addition, the provincial British Columbia government, a long-time supporter of TRIUMF, has already agreed to provide approximately $10 million for conventional construction. The nature of the accelerator contributions to the LHC has not been finally decided, although two areas are under discussion - the upgrade of the accelerator chain, and construction of the two 'beam cleaning' insertions. The former would involve provision of various new systems (radiofrequency, magnets, power supplies, kickers, etc) for the Booster, PS and SPS synchrotrons; indeed activity is already underway in some areas, such as model studies for a new 40 MHz system for the PS. The acronym of the new facility, ISAC-1, is short for Isotope Separator & Accelerator. A prototype first stage already exists in TRIUMF. ISAC-1 will use the intense proton beam from the TRIUMF cyclotron to create powerful beams of exotic, short-lived, radioactive nuclei which will be accelerated in a new structure

    In July 1976, an industrial accident contaminated a residential area surrounding Seveso, Italy, with high levels of 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD). The exposure was acute, relatively pure, and affected more than 45,000 men, women, and children. By February 1978, 193 chloracne cases, mostly children, had been identified in the exposed population. Twenty years after, we conducted a case-control study on subjects diagnosed with chloracne and control subjects, who had not developed chloracne after the accident, to evaluate their TCDD plasma levels, as well as the exposure-response relationship and possible determinants of susceptibility to TCDD effects in this population.

    In this paper, we discuss a number of issues emerged from our twenty-year long experience in applying the Residue Number System (RNS) to DSP systems. In early days, RNS was mainly used to reach the maximum performance in speed. Today, RNS is also used to obtain powerefficient (tradeoffs speed......-power) and reliable systems (redundant RNS). Advances in microelectronics and CAD tools play an important role in favoring one technology over another, and a winning choice of the past may become at disadvantage today. In this paper, we address a number of factors influencing the choice of RNS as the winning solution...

    The accident at the Chernobyl NPP (nuclear power plant) was the most serious ever to have occurred in the history of nuclear energy. The consumption of contaminated foodstuffs in affected areas was a significant source of irradiation for the population. A wide range of different countermeasures have been used to reduce exposure of people and to mitigate the consequences of the Chernobyl accident for agriculture in affected regions in Belarus, Russia and Ukraine. This paper for the first time summarises key data on countermeasure application over twenty years for all three countries and describes key lessons learnt from this experience. (review)

The vicious circle determined by three crises – one political, another social-institutional and last, but not least, a cultural one, continuously weakened the state for the last twenty years. Romania will overcome the economic crisis but the key for walking out of the above-mentioned circle would be the real transformation of its core systems – political, institutional and educational.

    The accident at the Chernobyl NPP (nuclear power plant) was the most serious ever to have occurred in the history of nuclear energy. The consumption of contaminated foodstuffs in affected areas was a significant source of irradiation for the population. A wide range of different countermeasures have been used to reduce exposure of people and to mitigate the consequences of the Chernobyl accident for agriculture in affected regions in Belarus, Russia and Ukraine. This paper for the first time summarises key data on countermeasure application over twenty years for all three countries and describes key lessons learnt from this experience. (review)

  11. Twenty-five years of post-Bretton Woods experience: some lessons

    Full Text Available In 1971 many academic economists were predicting that the Bretton Woods system of fixed parities would collapse. Some, most notably Milton Friedman, became excited about the possibility of a floating system because the benefits of international capital mobility can only be achieved through the flexibility in the exchange rate. These economists argued that a floating exchange rate system can ensure positive results more than the fixed parities system. Twenty-five years later, however, there is still no consensus on the matter. The author reviews the post-Bretton Woods experience to highlight some policies and approaches that might be helpful for the future.

    Space breeding is a novel effective approach to crop mutational improvement, which was firstly founded by the chinese scientists in 1987. A national collaborative research network has been established and significant achievements have been made during the past twenty years. More than forty new mutant varieties derived from space mutagenesis in rice, wheat, cotton, sweet pepper, tomato, sesame and alfalfa have been developed, officially released and put into production. A series of useful rare mutant germplasms which might make a great breakthrough in crop grain yield and/or quality improvement have been obtained. Technique innovations in space breeding and ground simulation of space environmental factors have been made good progresses. Intellective property right protection and industrialization of space mutation techniques and mutant varieties, exploration of the mechanism of space mutation induction have also been stably advanced. In this paper, the main achievements of crop space breeding in the past twenty years had been reviewed. The perspective development strategies of space breeding were also discussed. (authors)

    1978-01-01

    Twenty-five years have passed since the European Coal and Steel commmunity was established. An attempt is made to show what economic integration is, what problems have arisen, and how the community has tried to overcome them. Three phases can be distinguished during the period under review--a first phase of growth in the coal industry between 1953 and 1957; a second phase marked by a plentiful supply of cheap hydrocarbons and a rapid reduction in coal output despite exceptional growth, linked with a parallel increase in overall energy requirements; and a third phase from 1973, marked by sharp price increases by the oil producing countries with repercussions on the world market in coal.

  17. Twenty years of renewable energy law; 20 Jahre Recht der Erneuerbaren Energien

    Mueller, Thorsten (ed.)

    2012-07-01

    The present volume was compiled as part of a project funded by the German Federal Ministry for Environment, Nature Conservation and Reactor Safety, one event under which was the seventh Wuerzburg conference on environmental energy law with the title ''Twenty Years of Renewable Energy Law'' which took place on 13/14 October 2010. It comprises 36 contributions which, from different scientific perspectives, take stock of the significance of renewable energies for climate protection and the energy supply, examine the developments of the past 20 years and draw conclusions for the future use of renewable energy. The authors are scientists from the areas of climate research, economics, political science, engineering, environmental psychology and jurisprudence who have dedicated their work to issues that directly or indirectly relate to the expansion of renewable energies. Together they have created an overall picture of renewable energies with its many different aspects and related topics, a picture that necessarily cannot be complete but which nevertheless provides many rich insights. The great majority of articles were written around the turn of the year to 2011, just after the granting of lifetime extension for German nuclear power plants. They thus only take sparse account of the diverse and for some part far-reaching changes in German energy policy that came about after the reactor disaster in Fukushima.

  18. Reactions to combat stress in Israeli veterans twenty years after the 1982 Lebanon war.

    During the war or shortly thereafter, the most common manifestation of combat induced psychopathology is combat stress reaction (CSR). The long-term consequences of CSR have so far received little scientific attention. The aim of this study was to examine whether CSR is a marker for long-term PTSD and other psychiatric comorbidities. Two groups of veterans from the 1982 Lebanon war were assessed 20 years after the war: one comprised 286 CSR casualties and the other comprised 218 matched non-CSR soldiers. Participants were assessed for PTSD, psychiatric symptomatology, social functioning, physical health, and postwar life events. Twenty years after the war, veterans with antecedent CSR reported more PTSD, psychiatric symptomatology and distress, social dysfunction, and health problems than did non-CSR veterans. We conclude that CSR should be seen as a marker for long-term psychiatric distress and impairment. In addition, the implications of combat-related trauma are broad and varied, and go beyond the narrow scope of PTSD.

  19. Twenty Years After the 1988 Yellowstone Fires: Lessons About Disturbance and Ecosystems

    The 1988 Yellowstone fires were among the first in what has proven to be an upsurge in large severe fires in the western USA during the past 20 years. At the time of the fires, little was known about the impacts of such a large severe disturbance because scientists had had few previous opportunities to study such an event. Ecologists predicted short- and long-term effects of the 1988 fires on vegetation, biogeochemistry, primary productivity, wildlife, and aquatic ecosystems based on scientific understanding of the time. Twenty-plus years of subsequent study allow these early predictions to be evaluated. Most of the original predictions were at least partially supported, but some predictions were refuted, others nuanced, and a few postfire phenomena were entirely unexpected. Post-1988 Yellowstone studies catalyzed advances in ecology focused on the importance of spatial and temporal heterogeneity, contingent influences, and multiple interacting drivers. Post-1988 research in Yellowstone also has changed public perceptions of fire as an ecological process and attitudes towards fire management. Looking ahead to projected climate change and more frequent large fires, the well-documented ecological responses to the 1988 Yellowstone fires provide a foundation for detecting and evaluating potential changes in fire regimes of temperate mountainous regions. ?? 2011 Springer Science+Business Media, LLC.

  20. Higher Alu methylation levels in catch-up growth in twenty-year-old offsprings.

    Directory of Open Access Journals (Sweden)

    Kittipan Rerkasem

    Full Text Available Alu elements and long interspersed element-1 (LINE-1 or L1 are two major human intersperse repetitive sequences. Lower Alu methylation, but not LINE-1, has been observed in blood cells of people in old age, and in menopausal women having lower bone mass and osteoporosis. Nevertheless, Alu methylation levels also vary among young individuals. Here, we explored phenotypes at birth that are associated with Alu methylation levels in young people. In 2010, 249 twenty-years-old volunteers whose mothers had participated in a study association between birth weight (BW and nutrition during pregnancy in 1990, were invited to take part in our present study. In this study, the LINE-1 and Alu methylation levels and patterns were measured in peripheral mononuclear cells and correlated with various nutritional parameters during intrauterine and postnatal period of offspring. This included the amount of maternal intake during pregnancy, the mother's weight gain during pregnancy, birth weight, birth length, and the rate of weight gain in the first year of life. Catch-up growth (CUG was defined when weight during the first year was >0.67 of the standard score, according to WHO data. No association with LINE-1 methylation was identified. The mean level of Alu methylation in the CUG group was significantly higher than those non-CUG (39.61% and 33.66 % respectively, P < 0.0001. The positive correlation between the history of CUG in the first year and higher Alu methylation indicates the role of Alu methylation, not only in aging cells, but also in the human growth process. Moreover, here is the first study that demonstrated the association between a phenotype during the newborn period and intersperse repetitive sequences methylation during young adulthood.

  1. Ten Years, Twenty Issues, and Two Hundred Papers of Numeracy: Toward International Reach and Transdisciplinary Utility

    2017-07-01

    Full Text Available This issue completes the first ten years of Numeracy. The purpose of this introductory editorial is to review what has happened to the journal in those ten years. In the twenty issues, Numeracy’s output has been 201 papers counting the one or two editorials per issue. More than 50% of the papers are full, peer-reviewed articles, including 13 papers in two theme collections. The others are peer-reviewed notes and perspectives, editor-reviewed book reviews (15% of the total, and a column by contributing co-editor, Dorothy Wallace. The current issue marks an upswing in the number of notes, and our first discussion/reply. The number of papers per year has been increasing (e.g., 66% more in the last three years than in the first three years. The download rate has increased from about 5,000 in the first two years to 5,000 in about 40 days now. The editorial goes on to document two main outcomes. First, the journal is gaining an international reach: more than half the downloads occur outside the United States now, and the number of contributions from outside the United States has increased from 4 in the first five years to 15 in the second five years. Second, the across-the-curriculum nature of quantitative literacy is coming to the fore. The transdisciplinarity of QL is strikingly evident in this issue, which is discussed in some detail, especially how it conforms to the mission of the Association of American Colleges and Universities. The editorial ends with some results from a small ad hoc study of Google Scholar Citation Profiles. The question was, of the profiles that used “numeracy” or “quantitative literacy” as keywords, what other keywords did those profiles use, and what were the source countries? The results show that (1 QL is very much an American term, (2 there is, metaphorically, a vast and interesting numeracy ecosystem out there for Numeracy to engage and serve, and (3 as we become more global, the transdisciplinary relevance

    Background Annals of Botany is a peer-reviewed plant biology journal. It was started in 1887, making it the oldest continuously published plant science title. A previous article [Jackson MB. 2015. One hundred and twenty-five years of the Annals of Botany. Part 1: the first 50 years (1887–1936). Annals of Botany 115: 1–18] summarized events leading to its founding, highlighted the individuals involved and examined the Journal’s achievements and management practices over the first 50 years to 1937. This second article covers the next 75 years. Sources of information The account draws principally on the Journal’s own records, minute books, financial accounts, original letters and notes held by the Annals of Botany Company, the Journal’s owners and managers. Content In 1937, its 51st year, the Journal was re-launched as Annals of Botany New Series and its volume numbers were reset to No. I. The present article evaluates the evolution of the New Series up to 2012, Annals of Botany’s 125th anniversary year. The period includes a 2-year run-up to World War II, six war years and their immediate aftermath, and then on through increasingly competitive times. The ebb and flow of the Journal’s fortunes are set against a roll-call of the often highly distinguished scientists who managed and edited the Journal. The article also examines an internal crisis in the 1980s that radically altered the Journal’s organization in ways that were, ultimately, to its benefit. The narrative is set against changes to economic conditions in Great Britain over the period, to the evolving nature and geographical distribution of much experimental plant science and to the digital revolution that, from the late 20th century, transformed the workings of Annals of Botany and of scientific publishing more generally.

    For nearly twenty five years, EDF has been checking that the actual operating transients are neither more severe nor more numerous than the design basis transients. This activity of transient cycle counting and bookkeeping has enabled EDF to own a database of more than 800 reactor.years for the PWR units. The current method of transient cycle counting is presented. In the paper, we will point out the main results of transient cycle counting and lessons learned. In general, the frequencies of transients are lower than the design frequencies. In few cases, they are higher, such as the transient frequencies of the RCS lines connected to auxiliary systems often due to operating procedures or particular periodic testing. Few periodic tests were not taken into account in the design basis transient file ; they have been detected thanks to the transient cycle counting. In the last 1980's, we achieved the first updating of the design basis transient file for the PWR 900 MWe series. In the early 1990's, we updated the design basis transient file of the PWR 1300 MWe series. In fact, since design and start-up, the operating conditions have been modified (fuel cycle with stretch-out, modification of the hot leg and cold leg temperatures for the PWR 1300 MWe,...). This was the cause of many unclassified transients. In the new design basis transient file, we have created new transients and increased the frequencies of some of them. This has enabled to consider the updated design basis transient file more representative of actual operating transients. For some years, we have increasingly associated the operators with the transient cycle counting concern. We noticed progress (decreased frequencies of most transients). (authors)

    The 25 year consolidation project was a result of a major re-thinking of CERN’s strategy for consolidating the LHC operation and the decision not to build a new PS Ring or a new Superconducting Proton Linac in early 2010. The work packages envisaged under this consolidation exercise came to a budget estimation of nearly 500 MCHF and were subjected to risk analyses to establish priorities and allocated funds based on limited spending profiles permitted under the CERN’s rolling Medium Term Plan, MTP.

    In April 1992, i.e. 20 years ago, fast train services started in Spain when high-speed trains were put into operation on the almost 500 km long Madrid-Cordoba-Sevilla railway line. Both the 1,435 mm UIC standard gauge and the 1 AC 25 kV 50 Hz overhead line voltage level meant a big step in the development. Today the Spanish high-speed network covers some 2,200 km of railway line, and more lines are planned or already under construction. (orig.)

    2006-12-01

    Full Text Available Twenty years ago, reading culture, library skills’ development used to be one of the core directions in research and teaching policy of the Department of Library Science at Vilnius University. Lateron, the topic was marginalized and today we return to the field that meanwhile has developed huge knowledge and experience base worldwide. A stimulus for the return was participation in BIBLIONOVA project. The aim of the article is to present a holistic approach towards information competency development in a modern academic institution. Prescriptive approach based on information literacy standards proved to be limited and not always effective in the academic environment.Information competency development is problem-specific, domain-specific, and disciplinespecific. It is interrelated with critical thinking, analytical skills as well as creativity and computerliteracy skills. Holistically, information competency development is an integral part of university’s life-long learning strategy. Critical success factors for information competency development areopen and problem-based learning and cooperative, inclusive strategies of the whole university. Academic libraries continue to play a major role in the process but the connections with faculty and administration in the process are of major importance.

  9. Twenty years research of chronic gamma-ray irradiation on seed crops

    International Nuclear Information System (INIS)

    Yamashita, Atsushi

    1983-01-01

    Twenty years of the works on the chronic gamma-ray irradiation of seed crops are summarized. Radiosensitivity and the mutation rate per unit exposure varies not only with the genetic factor but also depend on whether treatment is given to seeds or growing plants. The relation between the radiosensitivity of seeds and growing plants also varies with plant species. In Hordeum, Avena and Nicotiana, the highest mutation rate obtained by the chronic irradiation of growing plants is similar to that in seed irradiation, but in Oryza and Setalia, chronic irradiation was two to three times more effective for attaining a higher mutation rate. The mutation spectrum also varies with the mutagen, the factors modifying the effects of mutagen, and the dose of mutagen. The suitability of a particular mutagenic treatment to a species should be taken into consideration in the evaluation of mutagenic treatment. For instance, NaN 3 is highly mutagenic to barley, but less mutagenic to rice. The gene ea7 controlling the maturing earliness of barley seems to be mutable in chronic irradiation, and the mutants obtained by chronic irradiation are healthy. The author emphasized that the chronic irradiation at the gamma-field is a useful mutagenic treatment, even though some negative results have been reported in European countries. (Kaihara, S.)

    2006-01-01

    Full Text Available The hypopigmented variant of mycosis fungoides (MF is charactrized by the presence of hypopigmented patches as the sole manifestation of the disease. This variant is usually observed in the dark skin of African or Asian individuals particularly children, but nevertheless is an uncommonly reported presentation of the disease. The incidence of hypopigmented MF in Caucasian patients and others of fair skin color is rare. We describe hypopigmented lesions arising in a twenty-year-old Saudi woman with type IV skin color. The diagnosis of mycosis fungoides stage IA was made based on the clinico-radiological and histological features. The patient responded well to PUVA therapy and is currently clear of lesions. MF should be considered in the differential diagnosis of hypopigmented macular lesions in patients of any skin color and age. Multiple skin biopsies must be performed on different occasions so as not to miss the diagnosis; and long term follow up is recommended since recurrence is common and occasional cases behave aggressively.

  11. Twenty Years of National Minority Protection in the Republic of Croatia

    Directory of Open Access Journals (Sweden)

    Siniša Tatalović

    2011-12-01

    Full Text Available The paper contains a review of policies towards national minorities in the Republic of Croatia in the past twenty years, with reference to the perspective of minority rights implementation. The topic has been analysed in relation to two independent variables – the influence of external factors, i.e. the international community, and internal political processes that have had influence on the realisation of national minority rights. Today, as a country and society on the eve of accession to the European Union, along with a legislatively developed and institutionally branched model of the implementation of national minority rights, we can not claim to have established permanent protection of their rights. The degree of national minority integration in society is the only true indicator of policy success in relation to national minorities. The goal of this policy ought to be complete integration of national minorities into public, cultural, economic and political life, but accompanied by the preservation of their cultural and national identity. The Croatian model has been set up in such a way, but the manner in which it functions will depend on the political will to implement it, the willingness of national minority members to be active subjects of social and political life, as well as on civil society and Croatian society as a whole.

  12. Twenty years of student sexual behavior: subcultural adaptations to a changing health environment.

    Netting, Nancy S; Burnett, Matthew L

    2004-01-01

    This twenty-year study analyzes changes in sexual behavior among students at Okanagan University College in British Columbia, Canada. Surveys conducted in 1980, 1990, and 2000 reveal a steady increase in safer sexual practices. Most students now question potential partners about their past, use condoms with a new sexual partner, and maintain fairly long-term monogamous relationships. Three sexual subcultures continue to coexist in fairly stable proportions: celibacy (about 30%), monogamy (about 60%), and free experimentation (about 10%). Each subculture has created its own response to the danger of HIV/AIDS: celibates exaggerate the danger they face, monogamists rely on love and fidelity for protection, and free experimenters have increased their use of condoms. While romantic feelings lead many monogamous couples to abandon condoms without objective HIV/AIDS knowledge, free experimenters still face the highest risk. Although they now use condoms more than half the time, their lifestyle, which involves multiple partners, risky sexual acts, and frequent drug and/or alcohol use, clearly remains dangerous. The persistence of distinct subcultures has implications for health education programs, which would be most effective if based on key values held by specific target groups.

    2017-09-01

    Full Text Available Salman Rushdie’s memoirs, essays and novels contribute to the appreciation of the contradictions in his outlook on life. His experiences in his family enable Rushdie to make efforts for objective and tolerant judgement of British lifestyle and culture. However, his isolation from the society in Britain despite his struggle for adaptation to British cultural values cause contradictions in his cultural identity. While Rushdie expresses his allegiance to India and its culture in The Ground Beneath Her Feet (1999, he reflects his alienation from his homeland in this novel as well. Similarly, in his Imaginary Homelands (1981-1991 whereas Rushdie questions the injustice and inequality caused by imperialism in The New Empire within Britain (1982, he justifies the colonialist discourse in Kipling (1990. He elaborates on the contradictions in his outlook on life in terms of his cultural ambivalence in his fictions such as Midnight’s Children (1981 and Shame (1983. However, in his latest novel, Two Years, Eight Months and Twenty-Eight Nights (2015, Rushdie reflects his cultural identity conflict in terms of rationalism-mysticism dichotomy. With the use of allegory as well as the lack of linearity in time and space, Rushdie justifies his cultural ambivalence in relation to the dynamism of contemporary world. Thus, Rushdie’s latest novel invites reading for its representation of the oppositions in his approach to life.

    At the University Department of Cardiovascular Surgery in Zagreb, Croatia, we treated 81 patients with primary intracardiac myxoma, in a period from January 1975 to December 1994. There were 55 female and 26 male pts, in age from 1 month to 80 years, mean 46+/-15 years. Clinical manifestations varied from no symptoms and very poor or no clinical signs to various manifestations of chronic or acute congestive heart failure, syncope and arrhythmias with or without systemic findings such as high erythrocyte sedimentation rate, anaemia, leucocytosis, elevated gamma globulin, thrombocytopenia or low grade fever, as well as cerebrovascular accidents due to tumour embolization. Cardiac symptoms were predominant in 54 pts (66.6%) and cerebrovascular in 20 pts (24.7%). Seven pts (8.6%) were symptomless and discovered accidentally, mostly regarding on an unexplained heart murmur. In almost all the patients preoperative diagnosis of intracardiac myxoma was sufficiently established by echocardiography. The tumour was located in the left atrium in 62 pts (76.5%) and in the right atrium in 19 pts (23.5%). Delay from the onset of symptoms to the diagnosis was 6 months in average (range 10 days to 25 months). The average waiting for the operation was 9 days (range from 1 to 60 days). The echocardiographic diagnosis was confirmed during intraoperative examination followed by histological analysis. All pts underwent excision of myxoma using cardiopulmonary bypass with core and topical hypothermia and cold crystaloid cardioplegia. According to the additional preoperative and intraoperative findings, in 6 pts sinchronous mitral valve reconstruction, in 3 pts artificial mitral valve implantation and in 2 pts atrial wall reconstruction was performed. There was no perioperative mortality. After the operation, we could not evaluate all the patients long enough, mostly because of some paramedical circumstancies, such as war, migrations, etc. Twenty two pts undevent evaluation for at least 5

    As the number of studies in the literature is increasing, orthopaedic surgeons highly depend on meta-analyses as their primary source of scientific evidence. The objectives of this review were to assess the scientific quality and number of published meta-analyses on orthopaedics-related topics over time. We conducted, in duplicate and independently, a systematic review of published meta-analyses in orthopaedics in the years 2005 and 2008 and compared them with a previous systematic review of meta-analyses from 1969 to 1999. A search of electronic databases (MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews) was performed to identify meta-analyses published in 2005 and 2008. We searched bibliographies and contacted content experts to identify additional relevant studies. Two investigators independently assessed the quality of the studies, using the Oxman and Guyatt index, and abstracted relevant data. We included forty-five and forty-four meta-analyses from 2005 and 2008, respectively. While the number of meta-analyses increased fivefold from 1999 to 2008, the mean quality score did not change significantly over time (p = 0.067). In the later years, a significantly lower proportion of meta-analyses had methodological flaws (56% in 2005 and 68% in 2008) compared with meta-analyses published prior to 2000 (88%) (p = 0.006). In 2005 and 2008, respectively, 18% and 30% of the meta-analyses had major to extensive flaws in their methodology. Studies from 2008 with positive conclusions used and described appropriate criteria for the validity assessment less often than did those with negative results. The use of random-effects and fixed-effects models as pooling methods became more popular toward 2008. Although the methodological quality of orthopaedic meta-analyses has increased in the past twenty years, a substantial proportion continues to show major to extensive flaws. As the number of published meta-analyses is increasing, a routine checklist for

    The first Summer Institute in Clinical Dental Research Methods, a faculty development program at the University of Washington, was offered in the summer of 1992 for sixteen participants. The primary objective of the program was to give clinical faculty members in dentistry an introduction to and an understanding of the fundamental principles and methods used in good clinical research. In the twentieth offering of the institute in 2011, there were thirty-five participants, and over the twenty institutes, there has been a cumulative total of 463 participants who have come from thirty U.S. states as well as forty-three countries outside the United States. The curriculum has expanded from the initial offering of biostatistics, clinical epidemiology, behavioral research methods, and ethics in clinical research to now include clinical trials, grantsmanship, data analysis, an elective in molecular biology, and a team project that provides participants with hands-on experience in research proposal development as members of an interdisciplinary team. Enrollment has doubled since the first year, yet exit evaluations of the program content have remained consistently high (rated as very good to excellent). One of the indicators of program quality is that at least 50 percent of recent participants indicated that they attended because the program was recommended by colleagues who had attended. There seems to be an ever-increasing pool of dental faculty members who are eager to learn more about clinical research methodology through the institute despite the intensive demands of full-time participation in a six-week program.

  18. Some Observations on Cultural Opposites in Contemporary China: Kunming and Beijing Twenty Years Later

    Directory of Open Access Journals (Sweden)

    2016-02-01

    Full Text Available This paper considers the cultural opposites observed in various segments of Chinese culture during the author's three stays in China over a period of twenty years. The first and second stay, in 1986 and 1989 respectively, coincided with the initial period of the implementation of modernization reforms in China, when their results were just beginning to be felt. The third stay was in 2009, towards the end of the third decade of reform implementation, at the time of an already developed marketoriented communism. The paper's main thesis is that most of the phenomena observed in present-day urban China can be assigned to opposite categories, namely Chinese-Western and traditional- contemporary. Cultural opposites have been observed in the sphere of tourism and the behavior of both Chinese and foreign visitors, in the use of Chinese and English in notices and signs in public places, and in the promotion of traditional and modern architecture. In addition, they have been noted in the presentation of arts and crafts and industrial products, in the manner of consumption of hot drinks, and in the combining of Chinese and foreign cuisine. They are also evident in a Beijing Opera performance adapted both to the modern Chinese and to foreigners, and in the traditional Chinese exercises and western dances performed in public parks. In conclusion, the paper suggests that the process of establishing connections between China and the West is being carried on in a moderate and controlled way. In the globalization process cultural opposites coexist and merge, imparting new features to Chinese culture.

    2016-02-01

    This is the Japanese translation of the Ukrainian National Report 'Twenty-five Years after Chernobyl Accident: Safety for the Future', published by the Ministry of Ukraine of Emergencies in 2011 (in Ukrainian and English). This Japanese translation is published as an outcome of the KAKENHI research project on liquidations of Nuclear Disasters in the World (headed by Tetsuji Imanaka), in which Shindo participates, and as a KUR report of the Research Reactor Institute at Kyoto University. The objective of publishing this Japanese translation is to provide basic information on how to overcome the consequences of a large-scale Nuclear Disaster for the wide range of public, including decision-makers and administrative staff. By doing so, this publication aims at invigorating discussions over measures to be applied for overcoming the consequences of the TEPCO Nuclear Disaster (started in 11th March 2011 at Fukushima), and at forming proper schemes to minimise the consequences on current and future generations. The original text of this translation tightly summarised the whole picture of the Chernobyl Nuclear Disaster, which had been the only large-scale Nuclear Disaster until 11th March 2011. More importantly, it describes all sorts of measures and schemes taken in Ukraine from 1986 to 2011 in order to overcome the consequences of the Chernobyl Nuclear Disaster, in a quite well structured manner. In other words, from the contents of this text, Japanese readers are able to learn a lot about the very problems currently facing with. Therefore, I wish many Japanese readers will read this text, and utilise the knowledge written here effectively to overcome the consequences of the TEPCO Nuclear Disaster. (J.P.N.)

  20. Twenty-six years experience of commercialization on potato irradiation at Shihoro, Japan

    Science.gov (United States)

    Kameyama, K.; Ito, H.

    2000-03-01

    The township of Shihoro is Japan's biggest and most advanced dairy and field farming district which has been producing potatoes as a key crop. The potato irradiation plant was built at Shihoro in 1973 with a potato processing complex and has been shipping some 15,000 tons of sprout-inhibited potatoes a year during the sprouting season. From a technical viewpoint, the radiation efficiency of the Shihoro irradiator is lower than that of the usual irradiation facility using a carton box. The success of the Shihoro irradiator is shown in that radiation processing has been effectively included into one of the storage systems of a huge potato distribution facility. The sprout-inhibited potatoes as such are no guarantee of better business derived from potatoes, but producers see the merit of this process, because it makes possible year-round plant operations and planned shipments, keeps employees in year-round service and prevents rural depopulation, with an increase in the volume of business by expanding the area under crop. Recently in Japan, many companies have interests in commercial irradiation of spices, medical herbs and farm animal feeds before application to common foods.

  2. Twenty-five years of co-management of caribou in northern Québec

    2003-04-01

    Full Text Available The Hunting Fishing and Trapping Co-ordinating Committee (HFTCC, created at the signature of the James Bay and Northern Quebec Agreement has been meeting regularly since 1977. Early in the process, it became clear that the perception of the role and powers of the Committee were not commonly shared by the native and non-native members of the Committee. Nevertheless, the Committee has been used primarily as a consultative body for wildlife related issues. Of all the files on which the Committee worked, Caribou management, (including the development of outfitting and commercial hunting for this species has been among one of the most discussed subjects during the meetings. An analysis of important decisions taken and of the process that led to them reveal that very rarely was the Committee able to formulate unanimous resolutions to the Governments concerning caribou management. In fact, only a few unanimous resolutions could be traced and many were ignored. This took place during a period of abundance and growth of the caribou herds. As a result, the Committee has gone through the cycle of growth of the George River Herd without a management plan, without a long term outfitting management plan and for the last 8 years, without a population estimate of the herds. This situation did not prevent the Committee from allocating quotas for a commercial hunt, open a winter sport hunt and to give permanent status to outfitting camps that were once established as mobile camps. It was hoped then that increased harvest would help maintain the population at carrying capacity. This short-term reaction however, never evolved into a more elaborate plan. Of course this must be looked at in the context of the HFTCC having a lot more to worry about than the Caribou. Although all members know of the population cycles of caribou, the decision process that must be triggered, should a crisis occur is not in place. This presently results into a polarization of concerned

    solution is no longer easily justifiable. The research efforts undertaken to better understand and control calcium carbonate precipitation and scale formation have paid off and have resulted in the standardisation of the treatment process and the control procedure of the cooling circuits by ELECTRABEL. The initial experience gained in the fossil power plants of AMERCOEUR (2 x 125 MW units) was finally successfully applied to plants 2 and 3 at TIHANGE. Since then, all of the conventional or combined cycle power plants have adopted the same treatment philosophy. Six units of between 125 and 1000 MW have been treated in this manner, some of them for over twenty years, without showing any signs of scale deposits. It is true that adaptations have had to be made in the control recommendations defined during the pilot trials, in order to allow for the impact of cathodic protections and certain cooling tower fills.

    This presentation emphasized the importance of developing an emergency plan to minimize any impacts in the event that something may go wrong when the clock changes over at midnight on December 31, 1999. It is usually impossible to anticipate what kinds of emergencies will happen. Planning for emergencies does not have to be an intimidating task. Hazard analysis is a subjective way to investigate what can go wrong, the likelihood of it happening relative to some other potential emergency, and the seriousness of the event. In general, emergency planning for Y2K should not be significantly different from planning for any other type of emergency. Y2K is not the emergency. The events that occur as a consequence of Y2K are. It is these events that should be the focus of a Year 2000 emergency plan

    Purpose: The authors designed data, methods, and metrics that can serve as a standard, independent of any software package, to evaluate dose-volume histogram (DVH) calculation accuracy and detect limitations. The authors use simple geometrical objects at different orientations combined with dose grids of varying spatial resolution with linear 1D dose gradients; when combined, ground truth DVH curves can be calculated analytically in closed form to serve as the absolute standards. Methods: DICOM RT structure sets containing a small sphere, cylinder, and cone were created programmatically with axial plane spacing varying from 0.2 to 3 mm. Cylinders and cones were modeled in two different orientations with respect to the IEC 1217 Y axis. The contours were designed to stringently but methodically test voxelation methods required for DVH. Synthetic RT dose files were generated with 1D linear dose gradient and with grid resolution varying from 0.4 to 3 mm. Two commercial DVH algorithms—PINNACLE (Philips Radiation Oncology Systems) and PlanIQ (Sun Nuclear Corp.)—were tested against analytical values using custom, noncommercial analysis software. In Test 1, axial contour spacing was constant at 0.2 mm while dose grid resolution varied. In Tests 2 and 3, the dose grid resolution was matched to varying subsampled axial contours with spacing of 1, 2, and 3 mm, and difference analysis and metrics were employed: (1) histograms of the accuracy of various DVH parameters (total volume, D{sub max}, D{sub min}, and doses to % volume: D99, D95, D5, D1, D0.03 cm{sup 3}) and (2) volume errors extracted along the DVH curves were generated and summarized in tabular and graphical forms. Results: In Test 1, PINNACLE produced 52 deviations (15%) while PlanIQ produced 5 (1.5%). In Test 2, PINNACLE and PlanIQ differed from analytical by >3% in 93 (36%) and 18 (7%) times, respectively.

    Purpose: A prospective study of sequential surgery, abdominopelvic radiotherapy and single agent alkylating chemotherapy was conducted to evaluate survival and toxicity in the management of ovarian carcinoma. Methods: From 1970-1976, 95 women with stage I-III epithelial ovarian carcinoma were scheduled to receive postoperative radiotherapy consisting of 20.0 Gy to the whole abdomen (1.0 Gy/day), a 29.75 Gy pelvic boost (1.75 Gy/day) and 10 subsequent courses of Melphalan (1 mg/kg/course). Endpoints were overall survival, disease-free survival(DFS), and acute and chronic toxicity. Results: The evaluable 94 patients included 19 stage I, 25 stage II, and 50 stage III. Of the latter, 21 had no palpable disease postoperatively (IIIN) and 29 had postoperative palpable disease (IIIP). Overall survival at 5, 10, 15 and 20 years was 42%, 30%, 23% and 22%. DFS for the entire group was 54% at 5 years and remained 50% from 10 to 25 years. All but two recurrences were noted within the first 27 months. No recurrence or treatment-related deaths occurred after 8 years. After 10 years, the survival of the study group became parallel to the general population. Prognostic factors were only related to stage (p<.001) and the presence of postoperative palpable disease(p<.001). DFS at 25 years was 95 % for stage I, 71% at 5 years and 66% from 10 to 25 years for stage II, and 17% at 5 years and 11% thereafter for stage III patients(p<.001). Although no stage IIIP patients were cured, 25% lived beyond 2 years. Five year DFS was significantly better in IIIN (45%) vs. IIIP (0%) patients (p<.001). The 65 patients without postoperative palpable disease, (stage I-IIIN) achieved DFS at 5 and 25 years of 69%, and 61%, respectively. Of 31 patients undergoing a second-look surgery, 84% were found to be free of tumor. Two recurred at 3.5 and 7 years after surgery. Acute tolerance was acceptable. Chronic toxicity included an 11.7% rate of small bowel obstruction requiring surgery and a 3% rate of

    Full Text Available Abstract Background Human metapneumovirus (HMPV is an important cause of acute respiratory illness in children. We examined the diversity and molecular evolution of HMPV using 85 full-length F (fusion gene sequences collected over a 20-year period. Results The F gene sequences fell into two major groups, each with two subgroups, which exhibited a mean of 96% identity by predicted amino acid sequences. Amino acid identity within and between subgroups was higher than nucleotide identity, suggesting structural or functional constraints on F protein diversity. There was minimal progressive drift over time, and the genetic lineages were stable over the 20-year period. Several canonical amino acid differences discriminated between major subgroups, and polymorphic variations tended to cluster in discrete regions. The estimated rate of mutation was 7.12 × 10-4 substitutions/site/year and the estimated time to most recent common HMPV ancestor was 97 years (95% likelihood range 66-194 years. Analysis suggested that HMPV diverged from avian metapneumovirus type C (AMPV-C 269 years ago (95% likelihood range 106-382 years. Conclusion HMPV F protein remains conserved over decades. HMPV appears to have diverged from AMPV-C fairly recently.

    A summary is presented of results of medical examinations of inhabitants of the Marshall Islands during the 20-year period following the exposure of Rongelap people to radioactive fallout in 1954. The initial effect observed was β burns of the skin of some individuals. Few significant findings were observed during the subsequent 9-year period, although an increase in miscarriages and stillbirths among the exposed women was noted. In 1963 some thyroid abnormalities and growth retardation of some children were noted. (177 references)

    Since 1993, the National Atomic Energy Commission (Argentina) has been involved in several IAEA Technical Cooperation Projects at interregional, regional and national levels, covering different aspects of the uranium production cycle. The TC referred projects can be listed as follows: - INT 2/015 “Supporting Uranium Exploration Resource Augmentation and Production Using Advanced Techniques” (2012 – Present). - RLA 3/006 - 010 “Upgrading of Uranium Exploration, Exploitation and Yellowcake Production Techniques taking Environmental Problems into Account” (2007 - Present). - ARG 2/014 “Development and Strengthening of the Uranium Mining Cycle Human Resources” (2012 – Present). - ARG 3/012 - 014 "Geology favourability, production feasibility and environmental impact assessment of uranium deposits exploitable by the in situ leaching technology (ISL)'' (2007 - Present). - ARG 3/009 “Development and use of biological techniques for uranium production (ARG 3/009)” (2003 - 2006). - ARG 3/008 “Prospection of uranium and other elements using gamma-ray spectrometry surveys” (2001 – 2005). - ARG 3/007 “Uranium Favorability and Exploration in Argentina” (1993 - 1997). It can be considered that the role of the technological transfer by the IAEA has been highly relevant for increasing the capability of strategically plan and more efficiently carry out the uranium production cycle projects in Argentina.

    Trends in the utilization of Heller myotomy for achalasia in the U.S. over time have not been previously described. Using the Nationwide Inpatient Sample (NIS) database, we analyzed patients undergoing Heller myotomy for achalasia over a 20-year period (1992-2011) to estimate rates of Heller myotomy, locations where the procedures were performed (rural, urban or teaching) and changes in technique (laparoscopic vs open) as well as outcomes of length of stay and in-hospital mortality. Over the last 20 years, the total number of Heller myotomies performed in the U.S. has increased (1576 cases in 1992 to 5046 cases in 2011, p = 0.001). These procedures are now being performed laparoscopically (0.9%-67.0%, p Heller myotomy at teaching institutions with decreased in-hospital mortality and shorter LOS. Copyright © 2017.

    After running a summer school for enthusiastic high school students for 25 years, we reached the point where three of my colleagues at the physics department, are exstudents from two physics courses offered (more than ten years ago) within our program. There are also graduates in some others Faculties in different universities. Here we would like to describe the evolution of this project since its beginning, with 60 students in an introductory physics class to the 3000 now attending (January 2014) the around 60 courses offered in almost all areas of knowledge, from theater to Biotechnology. Lately, as we became aware of the relevance of teaching sciences to young kids in elementary school, we started a winter section addressing this group of students. The courses are mainly a hands on experience. In this talk we will comment about our learning experience working on this kind of projects and our projections for the future.

    Estrogens play a critical role in many aspects of physiology, particularly female reproductive function, but also in pathophysiology, and are associated with protection from numerous diseases in premenopausal women. Steroids and the effects of estrogen have been known for ∼90 years, with the first evidence for a receptor for estrogen presented ∼50 years ago. The original ancestral steroid receptor, extending back into evolution more than 500 million years, was likely an estrogen receptor, whereas G protein-coupled receptors (GPCRs) trace their origins back into history more than one billion years. The classical estrogen receptors (ERα and ERβ) are ligand-activated transcription factors that confer estrogen sensitivity upon many genes. It was soon apparent that these, or novel receptors may also be responsible for the "rapid"/"non-genomic" membrane-associated effects of estrogen. The identification of an orphan GPCR (GPR30, published in 1996) opened a new field of research with the description in 2000 that GPR30 expression is required for rapid estrogen signaling. In 2005-2006, the field was greatly stimulated by two studies that described the binding of estrogen to GPR30-expressing cell membranes, followed by the identification of a GPR30-selective agonist (that lacked binding and activity towards ERα and ERβ). Renamed GPER (G protein-coupled estrogen receptor) by IUPHAR in 2007, the total number of articles in PubMed related to this receptor recently surpassed 1000. In this article, the authors present personal perspectives on how they became involved in the discovery and/or advancement of GPER research. These areas include non-genomic effects on vascular tone, receptor cloning, molecular and cellular biology, signal transduction mechanisms and pharmacology of GPER, highlighting the roles of GPER and GPER-selective compounds in diseases such as obesity, diabetes, and cancer and the obligatory role of GPER in propagating cardiovascular aging, arterial

    Full Text Available Objective: This study was conducted to reassess the concepts established over the past 20 years, in particular in the last 5 years, about the use of methylene blue in the treatment of vasoplegic syndrome in cardiac surgery. Methods: A wide literature review was carried out using the data extracted from: MEDLINE, SCOPUS and ISI WEB OF SCIENCE. Results: The reassessed and reaffirmed concepts were 1 MB is safe in the recommended doses (the lethal dose is 40 mg/kg; 2 MB does not cause endothelial dysfunction; 3 The MB effect appears in cases of NO up-regulation; 4 MB is not a vasoconstrictor, by blocking the cGMP pathway it releases the cAMP pathway, facilitating the norepinephrine vasoconstrictor effect; 5 The most used dosage is 2 mg/kg as IV bolus, followed by the same continuous infusion because plasma concentrations sharply decrease in the first 40 minutes; and 6 There is a possible "window of opportunity" for MB's effectiveness. In the last five years, major challenges were: 1 Observations about side effects; 2 The need for prophylactic and therapeutic guidelines, and; 3 The need for the establishment of the MB therapeutic window in humans. Conclusion: MB action to treat vasoplegic syndrome is time-dependent. Therefore, the great challenge is the need, for the establishment the MB therapeutic window in humans. This would be the first step towards a systematic guideline to be followed by possible multicenter studies.

    The aim of this study was to analyze maxillofacial region fractures during the past 20 years in the Department of Maxillofacial Surgery in Prishtina. We have analyzed the histories of all patients with trauma who were hospitalized in the Department of Maxillofacial Surgery in Prishtina since the opening of the clinic in 1983 through 2005. Narrowing the subject of our research, we concentrated on fractures of the maxillofacial region treated at the Clinic of Maxillofacial Surgery for the period 2001-2005. We have analyzed those fractures and compared them with the period from 1983 to 2005 only when it was reasonable. During this period, 1,945 patients were treated for trauma in the maxillofacial region by the Department of Maxillofacial Surgery. This group included 19.8% females and 80.2% males. The largest age group were those between 20 and 20 years of age. Causes of trauma for both periods were predominantly traffic accidents; however, during the period 2001-2005, interpersonal conflicts were increasingly the cause of fractures. Interpersonal conflict as a cause of maxillofacial trauma has risen in recent years. With this increase the methods of treating fractures in this region are also changing.

  15. The fate of stranded oil at the BIOS site twenty years after the experiment

    As part of the 1981 Baffin Island Oil Spill (BIOS) Project, 15 cubic metres of aged crude oil was released onto the shores of an experimental beach at Cape Hatt, northern Baffin Island, Canada. The oil was left to weather naturally and the distribution, quantity and character of the oil was monitored over time. The experiment provided a unique opportunity to study and sample oil as it weathers over a 20 year period in a low-energy, arctic environment. Over the 20 years of the study, the oil was exposed to weathering processes for about 40 months during ice-free periods. While most of the stranded oil was removed in the first few months of open water immediately following the experiment, some small surface patches still persist. It was noted that there has been very little change in the distribution or in the physical condition of the oil patches between 1993 and 2001. Geochemical analysis reveals that some samples are unaltered despite more than 20 years of exposure to elements. Other samples indicate that biodegradation and photo-oxidation play a major role in removing most of the components of the oil in this low-energy arctic environment. Some highly biodegraded samples had less than 87 per cent of the original hydrocarbons. The study revealed that there are 4 stages in the evolution of the stranded oil: (1) initial rapid refloating of oil during the first 24 to 48 hours in 1981, (2) period of relative stability up to the formation of an asphalt pavement within 4 open-water months, (3) degradation of an asphalt pavement in the upper intertidal zone over a 10-month open-water period from August 1983 to August 1989, and (4) disintegration of the pavement after 1989 and before August 1991, with soft interstitial surface oil still present in 2001. 21 refs., 1 tab., 1 fig

    Epicardial pacemaker implantation is the favored approach in children weighing pacemaker implantation in neonates and infants from 1987. To date there have been no long-term follow-up reports of what is for many a controversial strategy. Between 1987 and 2003, 37 neonates and infants-median age 6.7 months (1 day to 3 years) and median weight 4.6 kg (2.7-10 kg)-had a permanent transvenous pacing system implanted. Pacing leads were placed into the right ventricular apex/outflow tract through a subclavian vein puncture with a redundant loop in the atrium. Three patients were lost to follow-up, 4 patients died from complications of cardiac surgery, and 2 patients had their system removed. At long-term follow-up in 28 patients at a median of 17.2 (range, 11.2-27.4) years, 10 patients have a single chamber ventricular pacemaker, 14 a dual chamber pacemaker, 3 a biventricular pacemaker, and 1 has a single chamber implantable cardioverter defibrillator. Subclavian vein patency was assessed in 26 patients. The overall subclavian vein occlusion rate was 10 of 13 (77%) 5 kg during long-term follow-up. After a median of 14.3 (range, 13.4-17.6) years of pacing, 7 patients continue with their original lead. Transvenous pacing in infants <10 kg results in encouraging short- and long-term clinical outcomes. Subclavian vein occlusion remains an important complication, occurring predominantly in those weighing <5 kg. © 2016 American Heart Association, Inc.

    Purpose: To evaluate the prognostic factors, patterns of failure, and late toxicity in patients treated with chemoradiation (CRT) for anal cancer. Methods and Materials: Consecutive patients with nonmetastatic squamous cell carcinoma of the anus treated by CRT with curative intent between February 1983 and March 2008 were identified through the institutional database. Chart review and telephone follow-up were undertaken to collect demographic data and outcome. Results: Two hundred eighty-four patients (34% male; median age 62 years) were identified. The stages at diagnosis were 23% Stage I, 48% Stage II, 10% Stage IIIA, and 18% Stage IIIB. The median radiotherapy dose to the primary site was 54 Gy. A complete clinical response to CRT was achieved in 89% of patients. With a median follow-up time of 5.3 years, the 5-year rates of locoregional control, distant control, colostomy-free survival, and overall survival were 83% (95% confidence interval [CI] 78-88), 92% (95% CI, 89-96), 73% (95% CI, 68-79), and 82% (95% CI, 77-87), respectively. Higher T stage and male sex predicted for locoregional failure, and higher N stage predicted for distant metastases. Locoregional failure occurred most commonly at the primary site. Omission of elective inguinal irradiation resulted in inguinal failure rates of 1.9% and 12.5% in T1N0 and T2N0 patients, respectively. Pelvic nodal failures were very uncommon. Late vaginal and bone toxicity was observed in addition to gastrointestinal toxicity. Conclusions: CRT is a highly effective approach in anal cancer. However, subgroups of patients fare relatively poorly, and novel approaches are needed. Elective inguinal irradiation can be safely omitted only in patients with Stage I disease. Vaginal toxicity and insufficiency fractures of the hip and pelvis are important late effects that require prospective evaluation.

    Full Text Available The objective of this study was to determine time trends (1982–2006 in total fat intake and changes in fatty acid structure intake in adolescents from Warsaw in view of increasing prevalence of obesity. Data come from four successive surveys randomly selected samples of adolescents (aged 11–15 years old, from Warsaw region. In total 9747 pupils have been examined, with response rate varying from 55% to 87% depending on year. Surveys were done always in the spring season of the year. Food intake was assessed by using 24 hours recall method of consumption by the pupils all products, including enriched, dishes and beverages as well as diet supplements, in the last 24 hours preceding the examination. The content of energy and nutrients was calculated by means of own computer softwares (DIET 2 and 4, taking into account successive revisions of the tables of food composition and nutritional values, as well as current Polish DRI. A significant decreasing trend was found in intake of total fat, of saturated fatty acids (SFA and cholesterol. The percentage of energy from total fat, also decreased both in boys (to 35,1% and girls (to 33,7%, what failed to reach the desired level below 30% of energy from fat which is recommended. Also significant decrease of SFA consumption was not satisfactory enough to approach the values <10% of energy recommended as was from 13% to 15%. Decreasing trends in fat intake was not in accordance with the trend in obesity prevalence in the adolescents as average BMI is going up. To stabilize the health-oriented changes especially in the diets of adolescents, further activity is desired from professionals working with prevention of adolescents obesity.

  20. Actinomycosis of Distal Phalanx Twenty Years after Flap Reconstruction of Index Finger: A Case Report

    Full Text Available Actinomycosis is a chronic granulomatous suppurative infection caused by anaerobic bacteria from genus Actinomyces which are normal flora of mouth, colon and vagina. Actinomycosis of upper extremity is rare. We report a case of actinomycosis of the distal phalanx of finger many years after flap reconstruction. The patient presented with two months’ history of chronic discharging sinus from the tip of his right index finger, which had sustained a degloving injury 20 years previously. It had been treated with an anterior chest wall flap which had healed uneventfully but was bulky due to excess tissue from the donor site. Radiograph revealed osetomyelitis changes of distal phalanx. Debulking surgery with curettage of the distal phalanx was done. Wound healing was uneventful. He was treated with six weeks of metronidazole and ciprofloxacin. The discharge from the distal phalanx cultured actinomycosis odontolyticus. Histopathology of the debrided tissue showed chronic inflammation. As far as we are aware, there are no reports of actinomycosis in a flap involving the finger treated previously with a chest wall skin flap. The infection was probably dormant for many years before manifesting as a discharging sinus. Although the finger flap was bulky, it was not problematic until it started to have serous discharge. With a thorough debridement of all infected tissue, six weeks of antibiotic was adequate. Ciprofloxacin was prescribed based on discharge culture sensitivity. Metronidazole was added as actinomycosis is anaerobic. Response was prompt as patient was not immunocompromised. At follow-up six months post-surgery the finger had recovered with good function. If not for the discharging sinus, patient would probably have tolerated his bulky finger for the rest of his life.

    Research on moderate drinking has focused on the average level of drinking. Recently, however, investigators have begun to consider the role of the pattern of drinking, particularly heavy episodic drinking, in mortality. The present study examined the combined roles of average drinking level (moderate vs. high) and drinking pattern (regular vs. heavy episodic) in 20-year total mortality among late-life drinkers. The sample comprised 1,121 adults ages 55-65 years. Alcohol consumption was assessed at baseline, and total mortality was indexed across 20 years. We used multiple logistic regression analyses controlling for a broad set of sociodemographic, behavioral, and health status covariates. Among individuals whose high level of drinking placed them at risk, a heavy episodic drinking pattern did not increase mortality odds compared with a regular drinking pattern. Conversely, among individuals who engage in a moderate level of drinking, prior findings showed that a heavy episodic drinking pattern did increase mortality risk compared with a regular drinking pattern. Correspondingly, a high compared with a moderate drinking level increased mortality risk among individuals maintaining a regular drinking pattern, but not among individuals engaging in a heavy episodic drinking pattern, whose pattern of consumption had already placed them at risk. Findings highlight that low-risk drinking requires that older adults drink low to moderate average levels of alcohol and avoid heavy episodic drinking. Heavy episodic drinking is frequent among late-middle-aged and older adults and needs to be addressed along with average consumption in understanding the health risks of late-life drinkers.

    The aim of this study was to compare the etiology, clinical course, selected diagnostic methods and efficacy of the treatment used in patients with infective endocarditis (IE) in the nineteen eighties and nineties. The study group comprised 300 patients with infective endocarditis hospitalized in the Institute of Cardiology in Warsaw in the following years: from 1982 to 1987 (150 patients: 75 successive patients with IE on the prosthetic valve and 75 successive patients with IE on the native valve), as well as from 1990 to 2003 (150 patients: 75 successive patients with IE on the prosthetic valve and 75 successive patients with IE on the native valve). In the nineties, immunological symptoms, embolism formation and progressive heart failure were diagnosed decidedly more frequently. Early prosthetic valve endocarditis (PVE) (up to 60 days after operation) occurred significantly more frequently in the eighties. The quantity of negative blood cultures in PVE has not decreased, it is still observed in over 20% of cases. For 20 years the etiology of PVE has remained the same, the dominant pathogen remains Staphylococcus. The frequency of PVE caused by Streptococci has markedly reduced. In both the decades analyzed the etiology of native valve endocarditis (NVE) was similar. In the eighties Streptococcus was predominant. In successive years the number of infections caused by Staphylococci was the same as that caused by Streptococci. The incidence of early PVE decreased in the nineties. More patients were treated surgically with lesser peri-operative mortality. A lower incidence of infective endocarditis on prosthetic valves caused by streptococci may signify better prophylaxis against infective endocarditis. Infective endocarditis with sterile blood cultures continues to occur frequently.

    Since 1968 we have employed supervoltage orbital radiation as treatment for severe progressive Graves' ophthalmopathy. A numerical ophthalmic index was used to asess pre- and post-treatment serverity. In the past 20 years we have treated 311 patients of whom 275 have been followed for {le} 1 year or until any eye surgery was performed. An orbital radiation dosage of 2000 rads in 2 weeks was used for the majority of patients (Series I and III). Series II patients received an orbital dose of 3000 rads in 3 weeks. Demographic differences were observed between these series, thus mandating presentation of the results of each separately. Analyses excluded any result achieved by any post-radiation surgical procedure on the eyes. Post-theraphy worsening of ophtalmopathy occurred in only 29 of 1025 observations. Improvement or complete resolution was observed within each category of eye involvement, but lack of favorable response was also recorded in significant numbers. Improvement in proptosis occurred with the lowest frequency and magnitude. About 30% of the patients required eye muscle surgery to correct residual diplopia. Analysis of the data by step-wise linear regression analysis enabled us a. to derive formulae predicting the problable response to radiation therapy according to sign and severity, and b. identify parameters which diminished the likelihood or the extent of a favorable response. The latter included male sex, never thyrotoxic, age greater than 60 years, and requirement for concomitant treatment for hyperthyroidism. No long-term adverse reactions attributable to the radiotherapy have been observed. We conclude that supervoltage orbital radiotherapy, combined with later eye muscle surgery if necessary, is an effective treatment strategy for progressive Graves' ophthalmopathy. (author).

    To investigate survival up to early adulthood for children with intellectual disability and compare their risk of mortality with that of children without intellectual disability. This was a retrospective cohort study of all live births in Western Australia between January 1, 1983 and December 31, 2010. Children with an intellectual disability (n = 10 593) were identified from the Western Australian Intellectual Disability Exploring Answers Database. Vital status was determined from linkage to the Western Australian Mortality database. Kaplan-Meier product limit estimates and 95% CIs were computed by level of intellectual disability. Hazard ratios (HRs) and 95% CIs were calculated from Cox proportional hazard regression models adjusting for potential confounders. After adjusting for potential confounders, compared with those without intellectual disability, children with intellectual disability had a 6-fold increased risk of mortality at 1-5 years of age (adjusted HR [aHR] = 6.0, 95%CI: 4.8, 7.6), a 12-fold increased risk at 6-10 years of age (aHR = 12.6, 95% CI: 9.0, 17.7) and a 5-fold increased risk at 11-25 years of age (aHR = 4.9, 95% CI: 3.9, 6.1). Children with severe intellectual disability were at even greater risk. No difference in survival was observed for Aboriginal children with intellectual disability compared with non-Aboriginal children with intellectual disability. Although children with intellectual disability experience higher mortality at all ages compared with those without intellectual disability, the greatest burden is for those with severe intellectual disability. However, even children with mild to moderate intellectual disability have increased risk of death compared with unaffected children. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full text: A 21-year-old female with multiple granulomas an the right iris with concomitant therapy refractive panuveitis was referred to the Department of Ophthalmology to exclude an ocular malignancy. The patient had a history of minimal change glomerulonephritis and cutaneous granulomas at the age of six years that were successfully treated with cyclophosphamide. Her visual acuity initially already reduced to 30 % decreased rapidly to 'counting fingers'. A clinical work-up including chest x-ray, spiral computed tomography of the lungs and a detailed serological examination including angiotensin converting enzyme showed no evidence of infection or neoplasia. Planar scintigraphy 24 hours after administration of 185 MBq Gallium-67 citrate demonstrated an intense tracer accumulation in both lacrimal glands. Salivary gland uptake was normal and there was only a faint accumulation in the mediastinum interpreted as normal. A biopsy of the right iris revealed a granulomatous non caseating inflammation diagnosed as sarcoidosis. A systemic combination treatment with prednisolone and methotrexate for 4 months could not control the inflammation. After therapy was changed to cyclosporine the inflammation decreased and visual acuity decreased to 60 %. Neither a 'lambda sign' (characteristic uptake of Ga-67 in intrathoracic lymph nodes resembling the Greek letter lambda) nor a typical 'panda sign' (bilateral salivary and lacrimal gland uptake of Ga-67) commonly present in sarcoidosis were seen in our patient. This case demonstrates that in individual patients with sarcoidosis, lacrimal gland uptake of Ga-67 may be the only significant noninvasive finding. (author)

    The purpose of this study was to examine gender disparities in dental leadership and academics in the United States. Nine journals that represent the dental specialties and high published impact factors were selected to analyze the percentage of female dentists' first and senior authorship for the years 1986, 1990, 1995, 2000, 2005, and 2008. Data on appointment status and female deanship were collected from the American Dental Association (ADA) survey, and the trends were studied. The proportion of female presidents in ADA-recognized specialty organizations was also calculated. Overall, the increase in first female authorship was not statistically significant, but the increase of last female authorship was statistically significant in a linear trend over the years. The percentage of tenured female faculty members and female deans in U.S. dental schools increased by factors of 1.7 and 9, respectively, during the study period. However, female involvement in professional organizations was limited. Findings from this study indicate that female participation in authorship and leadership has increased over time. Nevertheless, females are still a minority in dental academics and leadership.

  12. Twenty years of universal vaccination against hepatitis B in Italy: achievements and challanges

    2012-04-01

    Full Text Available Viral hepatitis B is a vaccine-preventable disease. Vaccination has proved to be safe and highly effective in reducing the incidence, the carrier rate and HBV-related mortality on a global scale. In Italy, universal vaccination against hepatitis B started in 1991 in infants as well as in adolescents, providing an outstanding record of safety and effectiveness. Within a few years, over 95% coverage was consistently reported. Today, some 17 million people are immune against hepatitis B and their immunity has been shown to be long-lasting. At present, no booster is required in healthy vaccinated people to sustain protection. Surveillance data from Italy have shown a clear overall decline in hepatitis B among successfully vaccinated individuals. Furthermore, a generation of children and young people (at present cohorts ranging from 0 to 32 years is emerging with practically no markers of HBV infection. Italy’s vaccination programme has resulted in substantial progress being made towards the prevention and control of hepatitis B. The vaccination programme must continue. Maintaining mandatory vaccination of infants and increasing HBV vaccination coverage in high-risk groups, including households of HBsAg carriers as well as immigrants, remain a priority for the future.

    2016-04-01

    The Modified Allan Variance (MAVAR) was originally defined in 1981 for measuring frequency stability in precision oscillators. Due to its outstanding accuracy in discriminating power-law noise, it attracted significant interest among telecommunications engineers since the early 1990s, when it was approved as a standard measure in international standards, redressed as Time Variance (TVAR), for specifying the time stability of network synchronization signals and of equipment clocks. A dozen years later, the usage of MAVAR was also introduced for Internet traffic analysis to estimate self-similarity and long-range dependence. Further, in this field, it demonstrated superior accuracy and sensitivity, better than most popular tools already in use. This paper surveys the last 25 years of progress in extending the field of application of the MAVAR in telecommunications. First, the rationale and principles of the MAVAR are briefly summarized. Its adaptation as TVAR for specification of timing stability is presented. The usage of MAVAR/TVAR in telecommunications standards is reviewed. Examples of measurements on real telecommunications equipment clocks are presented, providing an overview on their actual performance in terms of MAVAR. Moreover, applications of MAVAR to network traffic analysis are surveyed. The superior accuracy of MAVAR in estimating long-range dependence is emphasized by highlighting some remarkable practical examples of real network traffic analysis.

    The Astronomy Department and McDonald Observatory at the University of Texas at Austin has and continues to offer a suite of different astronomy based K-12 teacher professional development programs. One of our longest running, and most successful programs, is reaching its 20th anniversary, the EXES Teacher Associate Program, which was started in 1998. The EXES Teacher Associate program features sustained and continued professional development opportunities for K-12 science and math educators. It consists of 6 times per year day-long meetings, coupled with other professional development opportunities provided at various times. In total, there are approximately 30 active members of the group currently, but more than 90 teachers have participated in this group over its 20 year history. The program has had astronomy education as its focus throughout its history, but different partnerships and collaborations with other programs have supported the group and have allowed for a variety of professional development opportunities and themes for educators to engage in. We will give an overview of this program, present evaluation data and teacher feedback related to program success and student impact, and highlight a few specific program opportunities that are unique and have been shown to be most impactful for participants.

    At global and regional scales, primary productivity strongly correlates with richness patterns of extant animals across space, suggesting that resource availability and climatic conditions drive patterns of diversity. However, the existence and consistency of such diversity–productivity relationships through geological history is unclear. Here we provide a comprehensive quantitative test of the diversity–productivity relationship for terrestrial large mammals through time across broad temporal and spatial scales. We combine >14,000 occurrences for 690 fossil genera through the Neogene (23–1.8 Mya) with regional estimates of primary productivity from fossil plant communities in North America and Europe. We show a significant positive diversity–productivity relationship through the 20-million-year record, providing evidence on unprecedented spatial and temporal scales that this relationship is a general pattern in the ecology and paleo-ecology of our planet. Further, we discover that genus richness today does not match the fossil relationship, suggesting that a combination of human impacts and Pleistocene climate variability has modified the 20-million-year ecological relationship by strongly reducing primary productivity and driving many mammalian species into decline or to extinction.

    Full Text Available Objective: To describe the sociodemographic and clinical profile of patients who underwent electroconvulsive therapy (ECT at a university general hospital. Method: In this retrospective study, records from all patients undergoing ECT between January 1988 and January 2008 at the psychiatric unit of the general hospital of Universidade Estadual de Campinas (UNICAMP were reviewed. Telephone contact was made with patients/relatives to collect follow-up data. Results: A total of 200 charts were reviewed. The majority of patients were women, with a mean age of 39 years, and history of psychiatric hospitalization. The main indications for ECT were depression and catatonia. Complications were observed in less than half of the cases, and most were temporary and not severe. There was a good psychiatric outcome for 89.7% of the patients, especially for catatonic patients (100%, p = 0.02. Thirty-four percent of the cases were later contacted by telephone calls, at a mean of 8.5 years between the procedure and the contact. Among these, three (1.5% reported persistent memory disorders and 73% considered ECT a good treatment. Conclusion: ECT has been performed according to international guidelines. In the vast majority of cases, undesirable effects were temporary and not severe. Response to ECT was positive in most cases, particularly in catatonic patients.

    A physically inactive lifestyle is associated with maladaptive patterns of personality development over relatively short follow-up periods. The present study extends existing research by examining whether this association persists over 20 years. Participants (total N = 8,723) were drawn from the Wisconsin Longitudinal Study Graduates and Siblings samples and the Midlife in the United States Study. Controlling for demographic factors and disease burden, baseline physical inactivity was related to steeper declines in conscientiousness in all three samples and a meta-analysis (β=-.06). The meta-analysis further showed that lower physical activity was associated with declines in openness (β=-.05), extraversion (β=-.03), and agreeableness (β=-.03). These findings provide evidence that a physically inactive lifestyle is associated with long-term detrimental personality trajectories.

    The union of catalysts and the automobile has been one of the greatest successes of heterogeneous catalysis over the last 25 years. Here, the history of automotive catalysis is briefly reviewed, followed by an assessment of where automotive catalysis stands today and where it is headed in the future. A key distinction between past automotive catalysis experience and that projected for the future is an increased focus on catalysts in upstream of power plant applications, such as on-board fuel processing units for fuel cell vehicles. Driven by ever tighter regulations, there will be continued research and development activity focused also on downstream applications (i.e. exhaust emission aftertreatment), especially for fuel-efficient, lean-burn vehicles, both diesel and spark-ignited.

    Infective endocarditis (IE) is still a disease with high morbidity and mortality. Its diagnosis and treatment are still a major challenge in clinical practice. There have been very few studies published about IE in Argentina. We reviewed all the studies about IE published in the Argentine Medicine Society from 1980 to 2003 and we analyzed demographic, clinical and bacteriological data. 27 studies with 628 patients were included. Mean age of patients was 50.7 years old. The most frequent clinical data were fever, murmur and elevated sedimentation rate. Stafilococcus spp was the most common causative organism, followed by streptococcus spp. The echocardiographic demonstration allowed the definitive diagnosis in 2/3 of the patients. The IE data of Argentina are not different from other data published in different countries and this study shows some clinical features of IE in Argentina.

    Along the last tventy years, in our country the quality assurance systems and the occupational medicine deeply interacted both in theoretical and practical fields of interest at three levels: (i) the need of preventive and therefore of occupational medicine in quality assurance systems; (ii) the need on reverse of quality in prevention and occupational mnedicine mainly in qualification and updating process; (iii) the evidence, proofs of efficacy or appropriateness of different preventive procedures and occupational physician activities; (iv) the connection with European and national legal directives and with technical or good practice norms. Finally we discuss about the role of occupational physician as the global consultant for enterprise, as a mandatory strategic technical figure in a typical multidisciplinary processes as the implementation of the quality systems.

    In Canada, nurse educators from five postsecondary institutions in the province of British Columbia established a collaborative nursing education initiative in 1989, with a vision to transform RN college diploma programs to baccalaureate degree programs. The principles, processes, and structures that served to develop and sustain this nursing education initiative are briefly reviewed. Curriculum, scholarship, and education legislation serve as platforms to critically explore a 25-year history (1989-2014) of successes, challenges, and transitions within this unique nursing education collaboration. The importance of curriculum development as faculty development, program evaluation as an adjunct to pedagogical scholarship, diversity of cross-institutional mandates, political interplay in nursing education, collegiality, and courageous leadership are highlighted. Nurse educators seeking to create successful collaborations must draw upon well-defined principles and organizational structures and processes to guide pedagogical practices and inquiry while remaining mindful of and engaged in professional and societal developments.

    Full Text Available Our contribution attempts to review basic vocational education programmes in Spain over the past 25 years. We intend to compare the evolution of these programmes in terms of conception and conditions of delivery in order to find out how different they are as skill-formation and remedial systems, as well as analysing how different political views have an impact upon such provision. We will focus on the current programmes in two regions in Spain where tourism is the main economic strength and source of employment. The authors have been working on several research projects investigating these issues since the late 1990s and we are currently working on two of them.

    Creativity has been a growing topic within the ACM community since the 1990s. However, no clear overview of this trend has been offered. We present a thorough survey of 998 creativity-related publications in the ACM Digital Library collected using keyword search to determine prevailing approaches......, topics, and characteristics of creativity-oriented Human-Computer Interaction (HCI) research. . A selected sample based on yearly citations yielded 221 publications, which were analyzed using constant comparison analysis. We found that HCI is almost exclusively responsible for creativity......-oriented publications; they focus on collaborative creativity rather than individual creativity; there is a general lack of definition of the term ‘creativity’; empirically based contributions are prevalent; and many publications focus on new tools, often developed by researchers. On this basis, we present three...

    1992-01-01

    A three year field study of 20 energy efficient houses and four conventional dwellings was conducted in Winnipeg, Manitoba to evaluate the performance of their building envelope systems. Ten of the houses were built with polyethylene air barriers and 14 using the Airtight Drywall Approach (ADA). All were newly constructed and used dry wood for the framing members with a wood moisture content (WMC) below 19 percent. Building envelope performance was evaluated by developing a comprehensive monitoring program which included measurements of wall, attic, and floor joist WMC levels, detailed thermographic examinations and regular airtightness testing. Over 13,000 WMC measurements were performed, 1,013 thermographic images recorded, and 167 airtightness tests conducted.

    In its 20th year, the Physician Assistant Clinical Knowledge Rating and Assessment Tool (PACKRAT) is a student self-assessment that can assist physician assistant (PA) students and PA program faculty in identifying strengths and areas in need of improvement in the didactic and clinical phases of PA education. In this reflection, we provide an overview of the history of PACKRAT and outline some of its benefits for students and PA programs, as well as its generative role in assessment within PA studies. Taking a broader view of PACKRAT's impact on assessment for the PA profession, we outline the research on its benefits and its use to maximize student performance, as well as how it has promoted the development of additional assessment tools.

    An overview of nearly thirty years development of waste gasification and pyrolysis technology is given, and some major general conclusions are drawn. The aim has been to give new developers an overview of earlier major attempts to treat MSW/RDF with thermochemical processes, gasification or pyrolysis. Research work in general is not covered, only R and D efforts that have led to substantial testing in pilot scale or demonstration. For further details, especially related to ongoing R and D, readers are referred to other recent reviews. The authors' view is that gasification of RDF with appropriate gas cleaning can play an important role in the future, for environmentally acceptable and efficient energy production. A prerequisite is that some of the major mistakes can be avoided, such as: (1) too rapid scale-up without experimental base, (2) unsuitable pretreatment of MSW to RDF and poor integration with material recycling, and (3) too limited gas/flue gas cleaning.

  9. Twenty Years of Progress on Global Ocean Tides: The Impact of Satellite Altimetry

    Egbert, Gary; Ray, Richard

    2012-01-01

    At the dawn of the era of high-precision altimetry, before the launch of TOPEX/Poseidon, ocean tides were properly viewed as a source of noise--tidal variations in ocean height would represent a very substantial fraction of what the altimeter measures, and would have to be accurately predicted and subtracted if altimetry were to achieve its potential for ocean and climate studies. But to the extent that the altimetry could be severely contaminated by tides, it also represented an unprecedented global-scale tidal data set. These new data, together with research stimulated by the need for accurate tidal corrections, led to a renaissance in tidal studies in the oceanographic community. In this paper we review contributions of altimetry to tidal science over the past 20 years, emphasizing recent progress. Mapping of tides has now been extended from the early focus on major constituents in the open ocean to include minor constituents, (e.g., long-period tides; non-linear tides in shelf waters, and in the open ocean), and into shallow and coastal waters. Global and spatially local estimates of tidal energy balance have been refined, and the role of internal tide conversion in dissipating barotropic tidal energy is now well established through modeling, altimetry, and in situ observations. However, energy budgets for internal tides, and the role of tidal dissipation in vertical ocean mixing remain controversial topics. Altimetry may contribute to resolving some of these important questions through improved mapping of low-mode internal tides. This area has advanced significantly in recent years, with several global maps now available, and progress on constraining temporally incoherent components. For the future, new applications of altimetry (e.g., in the coastal ocean, where barotropic tidal models remain inadequate), and new mission concepts (studies of the submesoscale with SWOT, which will require correction for internal tides) may bring us full circle, again pushing

    Early research of work disability in the 1980s showed a complexity of factors influencing pain and health-related functional limitation at work; hence, multidisciplinary perspectives were necessary to understand the complex interplay between biomechanical, organizational, social, and psychological factors impacting work disability. To address this need, the Journal of Occupational Rehabilitation was founded in 1991 with the goal of providing a scientific, yet practical forum for presenting multidisciplinary research and practice in work disability. Now, the 20-year collection of articles in the Journal reflects important trends and directions in the field of occupational rehabilitation. We conducted a retrospective summary of the past 20 years of the Journal of Occupational Rehabilitation, including its inaugural goals and intent, rates of submission and acceptance, trends in the types of articles published, study topics, global distribution of authors, and future directions. The original goal of providing a multidisciplinary scientific and practical forum has been met, but current trends reflect a maturing scientific evidence base, with less representation of employer-based case studies and practical innovations. There has been a dramatic increase in the international representation of studies, authors, and peer reviewers outside of the US. Also, published studies now address work disability for a larger number of health concerns. Contributions to the Journal continue to reflect a multidisciplinary perspective, but the Journal has seen significant changes with respect to international representation, the expanding study of non-musculoskeletal sources of work disability, and the maturing scientific evidence base in the field of occupational rehabilitation. Future volumes of the Journal will likely reflect continuing changes in the global economy, workforce fitness, and job demands.

  11. Twenty-year trends in benzodiazepine dispensing in the Australian population.

    Considerable concern has been expressed about overprescribing of benzodiazepines and related harms. Past analyses have relied on World Health Organization-defined daily doses (DDD) which are sometimes out of keeping with clinical usage. This study examines 20-year (1992-2011) trends of benzodiazepine dispensing in Australia using both DDD and Ashton equivalent dose. Data from the Drug Utilisation Sub-Committee and the Pharmaceutical Benefits Scheme (PBS) website were analysed. Trends in number of prescriptions, DDD/1000 people/day and DDD/prescription were examined over time, and between states/territories. In the 20-year period, 174 080 904 scripts were recorded, with temazepam the most dispensed benzodiazepine (35% of scripts), followed by diazepam (23%). Overall recorded utilisation fell from 27.7 DDD/1000 people/day in 1992 to 20.8 in 2011 (24.9% decrease). There were striking changes in use of individual benzodiazepines over time, with reductions in oxazepam and flunitrazepam and dramatic increases in alprazolam. Since 1998, there has been a steady increase, albeit modest, in per script DDD. The DDD/1000 people/day for items dispensed through PBS/Repatriaton-PBS was highest in Tasmania and lowest in Northern Territory. Despite a modest overall decline in the amount of benzodiazepine dispensed, the level of use is still likely to reflect relative over-prescribing given the paucity of accepted indications for long-term use. Since 1998, there was a polynomial increase in quantity dispensed per script. The WHO-defined DDD for clonazepam seems inappropriate and could impede monitoring of its abuse. Other problems include lack of national data for medications not subsidised on PBS/Repatriation PBS. A broad policy approach is required, not one which targets only one particular benzodiazepine. © 2013 The Authors; Internal Medicine Journal © 2013 Royal Australasian College of Physicians.

    Splenic preservation is the standard of care for hemodynamically stable children with splenic injuries. We report a 20-year single-institutional series of children with splenic injuries managed without a splenectomy. Children evaluated and treated for blunt splenic injury at Boston Children's Hospital from 1994 to 2014 were extracted from the trauma registry. Demographics, clinical characteristics, complications, and outcomes were reviewed. Three time-periods were evaluated based upon the development and modification of splenic injury clinical pathway guidelines (CPGs). Survival was defined as being discharged from the hospital alive. 502 suffered isolated splenic injuries. The median AAST grade of splenic injury increased across the three CPG time periods (psplenic-injury related mortalities occurred. Hospital length of stay decreased significantly secondary to splenic injury CPGs (psplenic injury, no patient died or underwent splenectomy. Hospital length of stay decreased across time, despite an increase in the severity of splenic injuries encountered. Splenectomy has become so unusual in the management of hemodynamically stable children with a splenic injury that it may no longer be a legitimate outcome marker. Copyright © 2015 Elsevier Inc.

    Selective attention allows us to ignore what is task-irrelevant and focus on what is task-relevant. The cognitive and neural mechanisms that underlie this process are key topics of investigation in cognitive psychology. One of the more prominent theories of attention is perceptual load theory, which suggests that the efficiency of selective attention is dependent on both perceptual and cognitive load. It is now more than 20 years since the proposal of load theory, and it is a good time to evaluate the evidence in support of this influential model. The present article supplements and extends previous reviews (Lavie, Trends in Cognitive Sciences, 9, 75-82. doi: 10.1016/j.tics.2004.12.004 , 2005, Current Directions in Psychological Science, 19, 143-148. doi: 10.1177/0963721410370295 , 2010) by examining more recent research in what appears to be a rapidly expanding area. The article comprises five parts, examining (1) evidence for the effects of perceptual load on attention, (2) cognitive load, (3) individual differences under load, (4) alternative theories and criticisms, and (5) the future of load theory. We argue that the key next step for load theory will be the application of the model to real-world tasks. The potential benefits of applied attention research are numerous, and there is tentative evidence that applied research would provide strong support for the theory itself, as well as real-world benefits related to activities in which attention is crucial, such as driving and education.

    The therapeutic drug monitoring (TDM) of antiepileptic drugs is a tool widely used in the management of epilepsy. In Morocco, this monitoring is carried out by the Centre Anti Poison et Pharmacovigilance (CAPM) since April 1995. This is a retrospective study spanning 20 years. It concerns the therapeutic drug monitoring of Phenobarbital (PB) of carbamazepine (CBZ) and valproic acid (VPA). Therapeutic drug monitoring of the 3 antiepileptic drugs represent 58.85% of all applications received by the CAPM. The dosage of PB was ranked first followed by that of CBZ and finally by the VPA. Weak demand for therapeutic drug monitoring in Morocco could be explained by the low number of neurologists in addition to social factors. With its affordable price by patients, PB is the most prescribed antiepileptic drug in our country, which explains the high demand for its dosage. As for the therapeutic drug monitoring of the antiepileptic drug, they were mainly related to age, the occurrence of adverse effects, the association antiepileptic drugs or in the case of verification of patient compliance. Efforts are required for promoting the interests of therapeutic drug monitoring of antiepileptic drug in the management of epilepsy in Morocco.

    2008-02-15

    In this historical review covering the past 25 years, we reflect on the content of manuscripts relevant to the Sport Performance section of the Journal of Sports Sciences. Due to the wide diversity of sport performance research, the remit of the Sport Performance section has been broad and includes mathematical and statistical evaluation of competitive sports performances, match- and notation-analysis, talent identification, training and selection or team organization. In addition, due to the academic interests of its section editors, they adopted a quality-assurance role for the Sport Performance section, invariably communicated through key editorials that subsequently shaped the editorial policy of the Journal. Key high-impact manuscripts are discussed, providing readers with some insight into what might lead an article to become a citation "classic". Finally, landmark articles in the areas of "science and football" and "notation analysis" are highlighted, providing further insight into how such articles have contributed to the development of sport performance research in general and the Journal of Sports Sciences in particular.

  20. Twenty Years of Precise Radial Velocities at Keck and Lick Observatories

    2015-10-01

    The precise radial velocity survey at Keck Observatory began over 20 years ago. Its survey of thousands of stars now has the time baseline to be sensitive to planets with decade-long orbits, including Jupiter analogs. I present several newly-finished orbital solutions for long-period giant planets. Although hot Jupiters are generally ``lonely'' (i.e. they are not part of multiplanet systems), those that are not appear to often have giant companions at 5 AU or beyond. I present two of the highest period-ratios among planets in a two-planet system, and some of the longest orbital periods ever measured for exoplanets. In many cases, combining Keck radial velocities from those from other long-term surveys at Lick Observatory, McDonald Observatory, HARPS, and, of course, OHP spectrographs, produces superior orbital fits, constraining both period and eccentricity better than could be possible with any single set alone. Stellar magnetic activity cycles can masquerade as long-period planets. In most cases this effect is very small, but a loud minority of stars, including, apparently, HD 154345, show very strong RV-activity correlations.

    1. Blag Slough, located in Indiana Dunes National Lakeshore, has received leachates from nearby fly-ash ponds for 13 years (1967-1980). We have monitored vegetation and sediment of Blag Slough since 1982, two years after the sealing of the fly-ash ponds and one year after the substrate was first exposed. The pH of the soil has increased one order of magnitude from 3.0 to 4.0 over the 23 years (1982-2005). If the pH further increases the solubility of many heavy metals will decrease, except for arsenic. We provide evidence that boron and zinc were bioaccumulating in the leaves of woody plants in 1984. The ratio of leaf concentration and soil concentration of aluminum suggests this element was not bioaccumulating in woody plants in 1984. 2. Soil concentrations of iron, aluminum, arsenic, and strontium were higher nearest the fly-ash ponds in 2005. The southwest corner of Blag Slough and middle position of transect X had the highest elevated levels of these metals and correlated with the occurrence of mixed spikerush association (dominated by Eleocharis olivacea). 3. Only a few exotic species occurred in the Blag Slough. Common reed (Phragmites australis) was among such species that occurred in three large clones. Other exotic species included dandelion (Taraxacum officinale), mullein (Verbascum thapsis), Jerusalem oak goosefoot (Chenopodium botrys), and sheep sorrel (Rumex acetosella). Ruderal species have occurred including thistle (Cirsium spp.), fire weed (Erechtites hieracifolium), and horseweed (Conyza canadensis). While occasional cattail (Typha) have been sampled and mapped in Blag Slough they have never persisted for very long. 4. Species richness leveled off between 1991 and 2005, except for Transect X that had a peak in 1986-7. After an extreme rainfall event in August 18, 1990, Transect V had an average water depth of 0.70 cm, W had 7.1 cm, and X had 26.90 cm. Richness in Transect X declined to a low level in 1990 and 1991 after the extreme flooding event

    Full Text Available ABSTRACT Objective: To report and compare the number and grade of major complications presented with non-endoscopic thermal discectomy and nucleoplasty for the treatment of discogenic axial lumbar pain using laser and radiofrequency. Methods: A 21 years retrospective study was conducted of the clinical charts of patients whose reason for consultation was axial lumbar pain from degenerative disc disease, and who underwent surgery using non-endoscopic discectomy and nucleoplasty (NEDN. Two groups were established; the first, NEDN with laser, and second, NEDN with radiofrequency. The number and types of complications reported in the case-series were counted, and their statistical differences determined. Results: The inclusion criteria were fulfilled by 643 of the medical charts. 26 complications were reported, the most common being radiculitis (n=12. Statistically significant differences were found between the complications occurring in the two groups (p=0.01. Conclusion: The number of complications showed statistically significant difference. The severity of the complications and adverse outcomes provide an argument for choosing one technology over the other. Training and the learning curve stage are important factors to be taken into account, to avoid complications.

    Full Text Available When looking ahead, it is really important to know where we have come from. This allows us to project identified trends and to reflect on the tremendous amount of change that can happen over a relatively short period.Reflect for a moment on the intensity of the debate regarding the use of intraocular lenses (IOLs in low-income settings in the 1990s. As they were still very expensive, some insisted that aphakic correction after surgery was the best approach for these countries. The subsequent availability of low-cost IOLs made the debate irrelevant. It dramatically changed our ability to provide modern IOL cataract surgery and control cataract blindness worldwide, and it laid the basis for VISION 2020. Other dramatic changes occurred with the introduction of ivermectin for onchocerciasis and azithromycin for trachoma, which gave us the ability to eliminate these two devastating and previously intractable causes of blindness. Our medical management of glaucoma or of age-related macular degeneration today is totally different from what it was 20 years ago, although there is still a long way to go. Our approach to refractive error has also altered dramatically, thanks to the recognition of its importance and the availability of high-quality, low-cost spectacles.So, given what we know about the past, what are the challenges we face in the future?

    This 25-y study monitored aquatic and terrestrial gamma-ray-emitting radionuclide levels near a nuclear power plant. It is the only known, long-term environmental survey of its kind. It was conducted neither by a utility owner, nor by a government agency, but rather by a private, environmental research institution. Compared to dozens of other flora and fauna, periphyton was found to be the best indicator to biomonitor the Susquehanna River, which runs near PPL Susquehanna's nuclear plant. Sampling began in 1979 before the first plant start-up and continued for the next 24 years. Monitoring began two months after the Three Mile Island accident of 28 March 1979 and includes Three Mile Island area measurements. Ongoing measurements detected fallout from Chernobyl in 1986, as well as I not released from PPL Susquehanna. Although this paper concentrates on radionuclides found in periphyton, the scope of the entire environmental program includes a wide variety of aquatic and land-based plants, animals, and inorganic matter. Other species and matter studied were fish, mussels, snails, crayfish, insects, humus, mushrooms, lichens, squirrels, deer, cabbage, tomatoes, coarse and flocculated sediment, and more. Results show periphyton works well for detection of radionuclide activity, even in concentrations less than 100 Bq kg (picocuries per gram amounts). Data indicate that PPL Susquehanna's radionuclide releases have had no known environmental or human health impact.

  5. Twenty years of children’s health monitoring: organization, results, conclusions

    Full Text Available Deep understanding of human potential reproduction, presenting it as a continuous cycle and reflecting the continuity of generations, is significant for the formation of health and development of children. Today’s children will determine the future of Russian society. It is they who in 10–15 years will be a major part of the labor and creative population, a demographic base of the country. The research into children’s problems through the prism of socio-economic development helps identify targets of the state many-sided policy. The article presents results of the long-term medical sociological monitoring on the formation of child health carried out by the Institute of Socio-Economic Development of Territories of RAS with the support of the Vologda Oblast Healthcare Department since 1995. The special monitoring study of health dynamics in real time is unique not only for the Vologda Oblast, but for Russia as well. It reveals the transformation of a personality and the dependence of these changes on direct and indirect factors. The work’s feature is that it addresses an extremely important and wide range of issues: whether man was born healthy or not, if he/she is unhealthy, then why and why he/she was born unhealthy; whether his/her health after the birth is improving or deteriorating; if health is changing, what causes the changes. The 15 year observations disclose the dynamics of child health in the conditions of transformation processes taking place in the country. If the official statistics only records certain health trends, the monitoring results allow us to talk about them at a qualitatively new level. They reveal the underlying causes of demographic processes. The conclusion is, on the one hand, obvious and, on the other hand, it can not be neglected: economic stability and orderly development of the social sphere are critical for family well-being and child health. The reverse situation leads to the destruction of the family

    Primary intestinal lymphangiectasia is a rare congenital disease described by Waldmann in 1961 that is a consequence of obstruction of the lymphatic drainage of the small bowel with secondary lymph vessel dilation. This distorts the architecture of the villi and causes a leakage of lymph into the intestinal lumen, resulting in protein-losing enteropathy and malabsorption. To describe the clinical, biochemical, radiologic, endoscopic, and histologic characteristics in children with primary intestinal lymphangiectasia. A retrospective observational, descriptive, cross-sectional study was conducted that reviewed the case records of children diagnosed with primary intestinal lymphangiectasia that were seen at the Department of Gastroenterology and Nutrition of the Instituto Nacional de Pediatría within the time frame of January 1, 1992 to September 30, 2012. Four patients were found that presented with primary intestinal lymphangiectasia. Three of them had been diagnosed before 3 years of age. All the patients presented with chronic diarrhea, edema, lymphopenia, hypocalcemia, and hypogammaglobulinemia, and 3 patients presented with hypocholesterolemia. Bowel transit time, endoscopy, and intestinal biopsies were characteristic of this pathology. Intestinal lymphangiectasia should be suspected when there is a clinical picture of chronic diarrhea and protein-losing enteropathy accompanied with edema at any level, as well as hypoalbuminemia, hypocalcemia, lymphopenia, hypogammaglobulinemia, and hypocholesterolemia, which are the main biochemical findings of this pathology. All children presenting with intestinal lymphangiectasia should undergo an upper gastrointestinal series with bowel transit time and endoscopy with biopsies taken at the level of the duodenum. Treatment includes diet and the periodic administration of albumin and gamma globulin. Copyright © 2013 Asociación Mexicana de Gastroenterología. Published by Masson Doyma México S.A.

    Background: Dietary patterns provide a summary of dietary intake, but to our knowledge, few studies have assessed trends in dietary patterns in the population. Objective: The aim was to assess 20-y trends in dietary patterns in a representative sample of the Geneva, Switzerland, population with the consideration of age, sex, education, and generation. Design: Repeated, independent cross-sectional studies were conducted between 1993 and 2014. Dietary intake was assessed by using a validated food-frequency questionnaire. Dietary patterns were assessed by using principal components analyses. Results: Among 18,763 adults, 1 healthy ("fish and vegetables") and 2 unhealthy ("meat and chips" and "chocolate and sweets") patterns were identified. Scores for the "fish and vegetables" pattern increased, whereas the "meat and chips" and "chocolate and sweets" pattern scores decreased in both sexes and across all age groups. The stronger increase in the "fish and vegetables" pattern score among the less well-educated participants led to a narrowing of educational differences (mean ± SD scores in 1993: -0.56 ± 1.39 compared with -0.05 ± 1.58 in low- compared with highly educated groups, respectively; P Generational analysis showed that older age groups tended to show smaller changes than younger age groups: the yearly score change in "chocolate and sweets" was -0.021 (95% CI: -0.027, -0.014; P y cohort compared with -0.002 (95% CI: -0.009, 0.005; P = 0.546) for the 45- to 54-y cohort. Conclusions: Three dietary patterns were identified; scores for the "fish and vegetables" pattern increased, whereas the "meat and chips" and the "chocolate and sweets" pattern scores decreased. The stronger increases in the "fish and vegetables" pattern score among the less well-educated participants led to a smaller difference in dietary intake across the different educational levels. © 2017 American Society for Nutrition.

    The Deckers Creek watershed in northern West Virginia (United States), containing a land area of 166 km{sup 2}, has along history of industrial development and attendant environmental abuses from both land and Water pollution practices. The water in Deckers Creek was sampled in 1974 at 9 locations along the main stem and resampled in 1999-2000 to determine water quality changes over this 25-year period. Water samples were analyzed for pH, acidity, alkalinity, iron, and calcium at both times, while aluminum, manganese, zinc, and fecal coliform (FC) bacteria densities were added in 1999-2000. Water at almost all sampling points showed lower acidity and metal contents in 1999-2600 compared with 1974. Water pH increased at the mouth from 5.4 in 1974 to 6.0 in 1999-2000. Acidity and iron concentrations, were decreased an average of 70% in the upper stretches of the creek. however, one major untreated point source of water from an abandoned underground mining complex continues to degrade the quality of-the creek in its lower stretches. In the upper section, the. water quality in Deckers Creek has improved due to decreased surface and underground coal-mining activities, reclamation of abandoned and recently permitted surface mined lands, and natural healing of past land use scars from timbering and mining over time. The decrease in mineral. extraction activities and the reclamation of disturbed lands has occurred due to the passage and enforcement of water quality and land reclamation laws and regulations.

    1992-05-01

    A three year field study of 20 energy efficient houses and four conventional dwellings was conducted to evaluate the performance of their building envelope systems. Ten of the houses were built with polyethylene air barriers and 14 using the airtight drywall approach (ADA). All were newly built and used dry wood for framing members, i.e. with a wood moisture content (WMC) below 19%. Building envelope performace was evaluated by developing a comprehensive monitoring program which included measurements of wall, attic and floor joist WMC levels, detailed thermographic examinations and regular airtightness testing. Over 13,000 WMC measurements were performed, 1013 thermographic images recorded and 167 airtightness tests conducted. Both the energy efficient and conventional building envelope systems performed satisfactory manner although fewer problems were found in the energy efficient houses. Lower mean WMC levels were measured in the walls and attics and fewer WMC excursions above 19% were recorded. The energy efficient houses also displayed fewer thermographic anomalies, particulary those of a severe nature. The energy efficient houses were found to be more airtight. No evidence of envelope degradation was found in the energy efficient houses. Both the polyethylene air barriers and the ADA system demonstrated predominately stable WMC levels, thermographic characteristics and airtightness. The building envelopes constructed using polyethylene barriers generally performed in a superior fashion to those which used ADA, although both systems provided satisfactory performance. WMC levels were slightly lower in the polyethylene houses as were the number of thermographic faults, particularly those of a severe nature. 11 refs., 28 figs., 10 tabs.

  10. Twenty-five years of biomonitoring lead in the Frankfurt/Main area.

    2002-01-01

    The present study is an example of the historical monitoring of heavy metals. The specific question it aims to explore is: to what extent has the lead content of selected organisms used for biomonitoring in Frankfurt/Main--one of the cities in Germany most heavily affected by automobile traffic--changed as a result of legislation on leaded gasoline? Data on the lead content of the moss species Bryum argenteum Hedw. from the years 1974, 1975 and 1978 and data on the lead content of the outer bark of the ash species Fraxinus excelsior L. from 1973 served as the basis for the repeated measurements. Remeasurement was successful in 76.5% (i.e. 124 trees at 26 growth sites). The study produced the following results: As was expected, the lead content of the short-term accumulator Bryum argenteum Hedw. was distinctly lowered with a decreasing particulate lead concentration. However, the reduction factor varied greatly between the different growth sites. On the other hand, the lead content measured in the outer bark layers of Fraxinus excelsior L. has risen markedly during the past two decades. Whereas in 1973 nearly all trees examined displayed very low concentrations of lead (225 ppm). Various factors have to be taken into account to explain this increase. First of all, bark is a long-term accumulator for heavy metals like lead and its enrichment capacity could have increased as the surface becomes rougher over time. Furthermore, lead is most probably leached out of the bark to a lesser degree now than in the 1970s, owing to the reduced concentration of sulphuric acid in the rain. The dramatic growth of automobile traffic in the Frankfurt/Main area during the period covered by the study undoubtedly plays an important role as well.

  11. Leibstadt nuclear power station (KKL): The Future after twenty years of operation

    2005-01-01

    Switzerland's largest power plant, KKL (1 165 MW BWR), is situated on the Swiss side of the Rhine River, not far from the entry of the Aare River. In 2003, the plant generated some 17% of the electricity consumed in the country. In line with the importance of the plant, it shareholders are all major Swiss power utilities. KKL was connected to the power grid in December 1984. Its construction cost amounted to approx. euro 3 200 million. After some backfitting measures at an expense of approx. euro 200 million, the plant is now in excellent technical shape. Generating costs, which were very high in the beginning, have been greatly reduced in the meantime. This was helped by a decrease of borrowed capital, the favorable development of interest rates and, above all, the rise in annual production. This, in turn, was achieved in various programs increasing plant power, and by shortening the annual revision outages. From the coming year onward, costs could be below Eurocent 3.3/kWh. Also the organization and the staff of te plant are prepared for the future. They have demonstrated their fitness in various national and international reviews. Also the political environment is favorable, by and large. In 2003, the Swiss voting population so clearly rejected the two opt-out initiatives that there has been a lasting positive change in the policy of continuing the operation of existing plants. Also for KKL, the waste management problem is still unsolved. This is due primarily to political reasons. The envisaged repository for low-level waste was rejected in a referendum in 2003. Technically and in its organization, the Leibstadt Nuclear Power Station is ready for the future. The electricity generated at Leibstadt is desired and accepted politically. (orig.)

    Full Text Available Throughout the 20th century, as well as in these early years of the 21th, several memoirs, autobiographical novels and orally-transmitted testimonies by Sephardic Jews have been published. These people knew the traditional community lifestyle of the Ottoman Empire before living through the social, cultural and political changes around the turn of the 20th century which brought about the decomposition of their Sephardic communities. Later they recreate —often in the new countries where they settled— this world that disappeared. The author analyzes here more than a dozen of such works, published by Sephardic women between 1987 and 2006. She calls attention to the way these women reconstruct their past and their identity in evoking the lifestyle, manners and customs of their original communities. Their testimonies differ significantly from those of the men, especially with regard to subjects such as family and social relationships.A lo largo del siglo XX y en lo que va del XXI se han publicado muchos libros de memorias, novelas autobiográficas y testimonios de historia oral de judíos sefardíes. Son gentes que conocieron la vida tradicional de las comunidades del antiguo imperio otomano, experimentaron los cambios sociales, culturales y políticos del paso de los siglos XIX al XX y la descomposición de las comunidades. Hoy recrean —la mayor parte de las veces, desde los nuevos países de emigración— ese mundo ya desaparecido. En este artículo la autora analiza una docena larga de este tipo de obras, publicadas por mujeres sefardíes entre 1987 y 2006. Enfatiza cómo estas mujeres reconstruyen su pasado y su identidad, evocando la vida, los usos y las costumbres de sus comunidades. Sus descripciones difieren sustancialmente de las de los hombres, en especial en lo que atañe a las relaciones familiares y sociales.

    The aim of this paper is to clarify and discuss how quality, relevance, attitudes, beliefs and transfer value act as underlying driving forces in the development of the Cultural Heritage theme in EIAs. One purpose is to identify and discuss some conditions that can better environmental assessment in order to increase the significance of EIA in decision-making with regard to Cultural Heritage. The main tools used are different research methods designed for analyses of quality and quality changes, primarily based on the relevant opinions of 160 people occupied with Cultural Heritage in EIA in Norway. The study is based on a review of 40 types of EIAs from 1991 to 2000, an online questionnaire to 319 (160 responded) individuals from 14 different backgrounds, and interviews with three institutions in Sweden and Denmark. The study confirms a steadily increasing quality on EIRs over time, parallel with an improvement of the way in which Cultural Heritage is treated in EIA. This is supported by both the interviews and the qualitative comments regarding the survey. Potential for improvements is shown to be a need for more detailed background material as well as more use of adequate methods. The survey shows the existence of a wide variety of negative views, attitudes and beliefs, but the consequences of this are difficult to evaluate. However, most certainly, negative attitudes and beliefs have not been powerful enough to be detrimental to the quality of Cultural Heritage component, as nothing in the study indicates that negative attitudes and myths are undermining the system of EIA. The study shows the importance of having on-going discussions on quality and quality change over time by people involved in EIA, and how this is a necessary condition for successful implementation and acceptance. Beliefs and negative attitudes can also be a catalyst for developing better practice and advancing new methodology. In addition, new EIA countries must be prepared for several years

  14. Twenty-four year record of Northern Hemisphere snow cover derived from passive microwave remote sensing

    Snow cover is an important variable for climate and hydrologic models due to its effects on energy and moisture budgets. Seasonal snow can cover more than 50% of the Northern Hemisphere land surface during the winter resulting in snow cover being the land surface characteristic responsible for the largest annual and interannual differences in albedo. Passive microwave satellite remote sensing can augment measurements based on visible satellite data alone because of the ability to acquire data through most clouds or during darkness as well as to provide a measure of snow depth or water equivalent. It is now possible to monitor the global fluctuation of snow cover over a 24 year period using passive microwave data (Scanning Multichannel Microwave Radiometer (SMMR) 1978-1987 and Special Sensor Microwave/Imager (SSM/I), 1987-present). Evaluation of snow extent derived from passive microwave algorithms is presented through comparison with the NOAA Northern Hemisphere snow extent data. For the period 1978 to 2002, both passive microwave and visible data sets show a smiliar pattern of inter-annual variability, although the maximum snow extents derived from the microwave data are consistently less than those provided by the visible statellite data and the visible data typically show higher monthly variability. During shallow snow conditions of the early winter season microwave data consistently indicate less snow-covered area than the visible data. This underestimate of snow extent results from the fact that shallow snow cover (less than about 5.0 cm) does not provide a scattering signal of sufficient strength to be detected by the algorithms. As the snow cover continues to build during the months of January through March, as well as on into the melt season, agreement between the two data types continually improves. This occurs because as the snow becomes deeper and the layered structure more complex, the negative spectral gradient driving the passive microwave algorithm

    Faragó, S.

    Full Text Available The Lajta Project covers 3,065 ha. Within this area crop cultivation is dominant. Fields are separated from each other by forest belts and tree rows, extending altogether over roughly 120 ha. This habitat structure characterized by cultivation of 12–15 field crops sustained partridge population with densities of 1.75 birds/km2 (1991. The Project started in 1991/1992 and aimed to increase the carrying capacity for grey partridge and other small game species living in the area. A full–time gamekeeper was employed and habitat improvements were initiated. Four years later, the breeding population increased to 10.1 birds/km2. Besides increased numbers of nesting pairs, the number of reared chicks also increased, from 5.1–11.2 individuals/km2 in 1990 to 27.3–38.4 individuals/km2 in 1994. However, field sizes did not change significantly. Although the lengths of field margins increased by approximately 25% (from 82 m/ha to 115 m/ha under the influence of habitat management, they still reached only half those found in the countries of Central Europe where private ownership of land properties is dominant. After the privatisation of fields in 1995 as part of the political change in Hungary —affecting approximately 50% of the project area— the possibilities of habitat improvement decreased, and the technological pressure on large–scale farming area increased. Following these processes the grey partridge population again decreased to 1.43 birds/km2 in 1997. As a result of the new management strategy applied in the project since 1996 we observed a slow increase in the breeding population, which stabilized at around 5 birds/km2, between 2007 and 2009. The August density increased in the same period from 4.5 birds/km2 to 13–17 birds/km2. During the two decades in which this research was conducted, chick mortality and winter mortality were extremely high. The key factors influencing grey partridge population dynamics in our study area seem to be

    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

The Forum was created as a contribution to the United Nations' ten years strategy for Chernobyl, launched in 2002 with the publication of Human Consequences of the Chernobyl Nuclear Accident - A Strategy for Recovery. In 2003-2004, two groups of experts from twelve countries, including Belarus, Russia and Ukraine, and from relevant international organizations have assessed the accident's environmental and health consequences. In early 2005, the group Environment, Coordinated by the IAEA, and the group Health, coordinated by the WHO, have presented their reports for Forum consideration. Both reports were considered and approved by the Forum at its meeting on 18-20 April 2005. This meeting also decided, inter alia, 'to consider he approved reports - as a common position of the Forum members, i.e., of the eight United Nations organizations and the three more affected countries, regarding environmental and health consequences of the Chernobyl accident, as well as recommended future actions, i.e., as a consensus within the United Nations system. Tis report presents the findings and recommendations of the Chernobyl Forum concerning Environmental effects of the Chernobyl accident. The Forum's report considering health effects is in process of publication under WHO responsibility.

    In 1979, about 2000 people in central Taiwan were intoxicated via rice oil consumption that was contaminated with polychlorinated biphenyls (PCBs). This 'Yu-cheng' incident was one of the two known major human PCB intoxication episodes. Twenty years after the intoxication, serum samples of 435 Yu-cheng victims, 414 adults and 21 children, were collected. Sixteen PCB congeners were analyzed with a gas chromatograph-electron capture detector. We found the median concentration of total PCBs in the adult serum was 1500 ng/g lipid, still substantially higher than that of the general population in Taiwan (3.7-fold) and most seafood consumers in the world. Most of analyzed PCB congeners in children were below or around the detection limits. Congener no. 138, however, had the highest concentrations, approximately accounting for 55% and 29% in the child and adult groups, respectively. Given that PCBs are persistent organic pollutants and endocrine disruptors, the concentrations and congener-specific profiles regarding the Yu-cheng victims provide valuable information for the investigation of such chemicals in humans. - Total serum PCBs in the Yu-cheng adult victims twenty years after the incident were still higher than that of the general population in Taiwan.

    To identify the frequency and causes of uveitis leading to visual impairment in patients referred to the Low Vision Service - Department of Ophthalmology - UNIFESP, over a twenty years period. In a retrospective study, medical records of 5,461 patients were reviewed. Data from the first clinical evaluation at the Low Vision Service were collected, patient's age, gender and cause of visual impairment were analyzed. Patients with uveitis had their chart reviewed for anatomical classification and clinical diagnosis. The mean age of the patients referred to the Low Vision Service was 42.86 years and the mean age of patients with uveitis diagnosis was 25.51 years. Retinal disorders were the most common cause of visual impairment (N=2,835 patients; 51.9%) followed by uveitis (862 patients, 15.7%). Uveitis was posterior in 792 patients (91.9% of uveitis) and toxoplasmosis was the most common diagnosis (765 patients, 88.7%). In our study, uveitis represents the second cause of visual impairment in patients referred for visual rehabilitation and toxoplasmic retinochoroiditis was the most common clinical diagnosis. It affects a young working age population with a relevant social and economic impact, but the early diagnosis and treatment can improve the quality of life of these patients.

    Population policy and the 5-year plans since 1951 in India are reivewed and evaluated in terms of limiting population growth. The family planning (FP) programs have not had a major impact on people's attitudes, practice of contraceptives, or the average fertility rate. Not enough attention has been paid to the interaction of demographic structure and economic and social development, and the implications for limiting population growth. Vital elements of a population policy are containing population growth, limiting births among the young and reproductive age groups, enhancing employment options for males and females, diversifying the economy, improving literacy and educational standards, improving urban/rural ratios, and balancing male/female ratios. Several approaches to FP programs are possible: long term measures to improve the social, economic, and demographic structure, and short term measures to immediately avert births. Long term approaches recognize the complexity of the problem. Rapid socioeconomic development is the best contraceptive for controlling India's population. A well conceived population education program can help, as will increasing the marriage age, preventing children from entering the labor market, increasing female education levels, providing old age pension and social security and other insurance, and providing maternity benefits for small families. Short term measures may provide temporary or permanent methods of averting births; i.e., contraceptives, sterilization, penalties and rewards for small families. However, it must not be a bureaucratic measure imposed from above. It must be a self generating process. The author suggests that simultaneous long and short term approaches are necessary. Research should be conducted to delineate which measures have the most impact on reducing fertility and policy be formulated in accordance with these answers. Compulsion is required, and government should not hesitate to step in. In rural areas

    Pickett, Susan E.

    2009-01-01

    Nuclear power technology has developed significantly over the past 60 years to the point that today it supplies the world with 15% of its electricity; and there are plans for continued development. However, the continued growth of nuclear power is not without challenges. The nuclear industry must remain competitive in the face of challenges ranging from environmental considerations and proliferation concerns to ensuring safe and often transparent operations. Understanding these and other issues, as well as their underlying causes, can help the industry leaders create more robust strategies and effectively implement nuclear fuel cycle decisions. Robust strategies are ones that can be effective even when circumstances change, due to events such as opposition, new scientific information, changes in resource availability, or introduction of competing technologies. Scenario planning is tool which can help planners and decision makers create a strategic conversation about the future and how to manage and plan in a time of accelerated change and complexity. In this paper, scenario planning is introduced and the development of nuclear power is examined against the back drop of four future scenarios, specifically looking at how variations in environmental quality, resource availability, security and proliferation, and safety may affect the development of nuclear power. The scenarios discussed provide a starting point to improve the understanding of issues and opportunities facing the global nuclear power industry and ultimately, to improve strategies for technology development. Such scenarios may be employed as a basis for collaboration and communication amongst the stakeholders involved in the development of nuclear technology. (author)

    A twenty-year follow-up study was carried out at Baiyun Obo Rare-earth Iron Mine in China, This mine has been mined since 1958. Its ore contains 0.04% of ThO 2 and 10% of SiO 2 . The purpose of this study is to investigate possible health effects in dust-exposed miners following long-term exposure to thorium-containing dusts and thoron progeny. By using the negative high voltage exhaled thoron progeny measurement system to estimate the miner's thorium lung burden. The highest thorium lung burden among 1 158 measurements of 638 miners was 11.11 Bq. The incidence of stage 0 + pneumoconiosis was increased among dust-exposed miners. An epidemiological study showed that the lung cancer mortality of the dust-exposed miners was significantly (p 2 and SiO 2 ) and thoron progeny. This is the first evidence in humans of the carcinogenicity after long-term inhalation of thorium-containing dusts and thoron progeny. The total person-years of observation for the dust-exposed miners and the controls were 62 712 and 34 672 respectively. (author)

  8. Twenty-Five Years of Gene Therapy for ADA-SCID: From Bubble Babies to an Approved Drug.

    2017-11-01

    Twenty-five years have passed since first attempts of gene therapy (GT) in children affected by severe combined immunodeficiency (SCID) due to adenosine deaminase (ADA) defect, also known by the general public as bubble babies. ADA-SCID is fatal early in life if untreated. Unconditioned hematopoietic stem cell (HSC) transplant from matched sibling donor represents a curative treatment but is available for few patients. Enzyme replacement therapy can be life-saving, but its chronic use has many drawbacks. This review summarizes the history of ADA-SCID GT over the last 25 years, starting from first pioneering studies in the early 1990s using gamma-retroviral vectors, based on multiple infusions of genetically corrected autologous peripheral blood lymphocytes. HSC represented the ideal target for gene correction to guarantee production of engineered multi-lineage progeny, but it required a decade to achieve therapeutic benefit with this approach. Introduction of low-intensity conditioning represented a crucial step in achieving stable gene-corrected HSC engraftment and therapeutic levels of ADA-expressing cells. Recent clinical trials demonstrated that gamma-retroviral GT for ADA-SCID has a favorable safety profile and is effective in restoring normal purine metabolism and immune functions in patients >13 years after treatment. No abnormal clonal proliferation or leukemia development have been observed in >40 patients treated experimentally in five different centers worldwide. In 2016, the medicinal product Strimvelis™ received marketing approval in Europe for patients affected by ADA-SCID without a suitable human leukocyte antigen-matched related donor. Positive safety and efficacy results have been obtained in GT clinical trials using lentiviral vectors encoding ADA. The results obtained in last 25 years in ADA-SCID GT development fundamentally contributed to improve patients' prognosis, together with earlier diagnosis thanks to newborn screening. These advances

    Pallavi Pharkya thinks a lot about the future. Pharkya, a Ph.D. candidate in materials science and engineering, works in the area of corrosion science, predicting how materials will perform over extended periods of time. Her particular focus is a nickel-chromium-molybdenum alloy called C-22, a highly corrosion-resistant metal. Pharkya's aim is to help determine whether containers made from C-22 can be used to store high-energy nuclear waste--for 10,000 years and longer. Pharkya's work is part of a plan by the U.S. Department of Energy to consolidate the country's nuclear waste in a single proposed repository. The proposed repository is in Yucca Mountain located in a remote Nevada desert. Currently about 70,000 metric tons of spent nuclear fuel and high-level radioactive waste are divided between approximately 100 sites around the country. The undertaking, Pharkya emphasizes, is massive. To study just the corrosion aspects of the packaging, Case is collaborating with eight other universities, five national labs and Atomic Energy of Canada Limited. Even with so many players, the study will likely take several years to complete. Heading the entire group is Joe Payer, a professor of materials science and engineering at Case and Pharkya's mentor. ''I came here to have the opportunity to work with Dr. Payer, an expert in corrosion, but I didn't know specifically what I would be working on'', Pharkya recalls. ''I was pretty thrilled when I learned about the vastness of the project--my research would be just a small part of this huge topic--and the impact of the research we would be doing''

    The first Björk-Shiley convexoconcave (BSCC) prosthetic heart valves were implanted in 1978. The 25th anniversary provided a stimulus to summarize the research data relevant to BSCC valve fracture, patient management, and current clinical options. Published and unpublished data on the risks of BSCC valve fracture and replacement were compiled, and strategies for identifying candidates for prophylactic valve reoperation were summarized. By December 2003, outlet strut fractures (OSFs), often with fatal outcomes, had been reported in 633 BSCC valves (0.7% of 86,000 valves implanted). Fractures still continue to occur, but average rates of OSFs in 60 degrees valves are now valve characteristics, especially valve angle and size, with weaker effects associated with other manufacturing variables. OSF risks are mildly lower among women than men but decline sharply with advancing age. The risks of valve replacement typically greatly exceed those of OSF. By comparing individualized estimated risks of OSF versus valve replacement, guidelines have been developed to identify the small percentage of BSCC patients (mostly younger men) who would be expected to have a gain in life expectancy should reoperative surgery be performed. Twenty-five years after the initial BSCC valve implants, fractures continue to occur. Continued monitoring of BSCC patients is needed to track and quantify risks and enable periodic updating of guidelines for patients and their physicians.

    Full Text Available Since its publication in 1933, Muiris O’Sullivan’s Fiche Blian ag Fás (Twenty Years A-Growing has been limited and distorted by critics who view the memoir through a lens shaped by prior assessments of Tomás Ó Criomhthain’s earlier Blasket autobiography, An tOileánach (The Islandman. Muiris Mac Conghail voices the standard perspective when he states, “It was the publication of Tomás Ó Criomhthain’s An tOileánach, in 1929, which both acted as an incentive and provided an exemplar to Muiris” (150. O’Crohan’s autobiography certainly inspired O’Sullivan; however, Muiris’s more literary sensibility set him on his own inscriptive journey during which he creates a new type of narrative, one which creatively interweaves oral traditions with the contours of the novel. As we investigate what Pádraig Ó Fiannachta terms the author’s nua scéalaíocht, or “new storytelling” techniques, we can more fully appreciate O’Sullivan’s subtle dexterities as both traditional storyteller and novelistic craftsman.

    Our survey used to collect data during a twenty-year long investigation into the science literacy of undergraduates (see Impey et al., this meeting), contains several questions addressing how students conceptualize astrology, and other pseudoscientific ideas. This poster presents findings from the quantitative analysis of some of these question responses from almost 10,000 undergraduate students enrolled in introductory astronomy courses from 1989 to 2009. The results from our data reveal that a large majority of students (78%) and half of science majors (52%) consider astrology either "very” or "sort of” scientific. Students performed comparatively better on all other pseudoscientific questions, demonstrating that belief in astrology is pervasive and deeply entrenched. We compare our results to those obtained by the NSF Science Indicators series, and suggest possible reasons for the high susceptibility to belief in astrology. These findings call into question whether our education system is adequately preparing students to be scientifically literate adults. You can help! Stop by our poster and fill out a new survey that will give us important parallel information to help us continue to analyze our valuable data set.

    Full Text Available Abstract All the Italian Centres in charge of screening, diagnosis, and follow-up of infants with congenital hypothyroidism participate in the Italian National Registry of affected infants, which performs the nationwide surveillance of the disease. It was established in 1987 as a program of the Health Ministry and is coordinated by the Istituto Superiore di Sanità. The early diagnosis performed by the nationwide newborn screening programme, the prompt treatment and the appropriate clinical management of the patients carried out by the Follow-up Centres, and the surveillance of the disease performed by the National Register of infants with congenital hypothyroidism are the components of an integrated approach to the disease which has been successfully established in our country. The aim of the Register is to monitor efficiency and effectiveness of neonatal screening, to provide disease surveillance and to allow identification of possible aetiological risk factors for the disease. During the past twenty years the active and continuous collaboration between the Register and the Italian Screening and Follow up Centres for Congenital Hypothyroidism allowed to perform a standardization of screening procedures and considerable improvements in the time at starting treatment and in the dose of therapy. Furthermore, the large amount and the high quality of information collected in the Register provided a unique opportunity for research into the disease. This because data collected in the Register are highly representative as referred to the entire Italian population with congenital hypothyroidism. The results derived from the epidemiological studies performed in these years, by using the Register database, contributed to deepen the knowledge of congenital hypothyroidism, to start identifying the most important risk factors for the disease, and to orient molecular studies aimed at identifying new genes involved in the aetiology of this condition.

  16. Twenty-Eight Years of Poliovirus Replication in an Immunodeficient Individual: Impact on the Global Polio Eradication Initiative.

    2015-08-01

    There are currently huge efforts by the World Health Organization and partners to complete global polio eradication. With the significant decline in poliomyelitis cases due to wild poliovirus in recent years, rare cases related to the use of live-attenuated oral polio vaccine assume greater importance. Poliovirus strains in the oral vaccine are known to quickly revert to neurovirulent phenotype following replication in humans after immunisation. These strains can transmit from person to person leading to poliomyelitis outbreaks and can replicate for long periods of time in immunodeficient individuals leading to paralysis or chronic infection, with currently no effective treatment to stop excretion from these patients. Here, we describe an individual who has been excreting type 2 vaccine-derived poliovirus for twenty eight years as estimated by the molecular clock established with VP1 capsid gene nucleotide sequences of serial isolates. This represents by far the longest period of excretion described from such a patient who is the only identified individual known to be excreting highly evolved vaccine-derived poliovirus at present. Using a range of in vivo and in vitro assays we show that the viruses are very virulent, antigenically drifted and excreted at high titre suggesting that such chronic excreters pose an obvious risk to the eradication programme. Our results in virus neutralization assays with human sera and immunisation-challenge experiments using transgenic mice expressing the human poliovirus receptor indicate that while maintaining high immunisation coverage will likely confer protection against paralytic disease caused by these viruses, significant changes in immunisation strategies might be required to effectively stop their occurrence and potential widespread transmission. Eventually, new stable live-attenuated polio vaccines with no risk of reversion might be required to respond to any poliovirus isolation in the post-eradication era.

    As result of the nuclear integration between Brazil and Argentina, in July 1991 the Agreement for Peaceful Uses of the Nuclear Energy (Bilateral Agreement) was signed and the Brazilian Argentine Agency for Accountancy and Control of Nuclear Material (ABACC) was created [1]. The main role assigned to ABACC was the implementation and administration of the regional control system and the coordination with the International Atomic Energy Agency (IAEA) in order to apply safeguards to all nuclear material in all nuclear activities of Argentina and Brazil. In December 1991 the IAEA, ABACC, Argentina and Brazil signed the Quadripartite Agreement (INFCIRC/435) [2]. The agreement establishes obligations similar to those established by model INFCIRC/153 comprehensive agreements. The Bilateral Agreement establishes that the Parties should make available financial and technical capabilities to support ABACC activities. In order to accomplish this challenge, the National Systems had to improve their structure and capabilities. Through the close interaction with the IAEA and ABACC, the national systems have been enriched by adopting new methodologies, implementing innovative safeguards approaches and providing specialized training to the regional inspectors. All of this also resulted in relevant technical improvements to the regional system as a whole. The approach of both neighborhoods controlling each other increased the confidence between the partners and permitted a better knowledge of their potentialities. The recognized performance of the regional system in the implementation of innovative, efficient and credible safeguards measures increased the confidence of the international community on the implementation of nuclear safeguards in Argentina and Brazil. In this paper, after twenty years of the creation of the ABACC System, the view of the Brazilian and Argentine National Authorities is presented. (authors)

    On its deadly run through the Caribbean last September, Hurricane Irma lashed northern Cuba, inundating coastal settlements and scouring away vegetation. Irma lent new urgency to a Cuban national plan, called Tarea Vida, or Project Life, that bans construction of new homes in threatened coastal areas, mandates relocating people from communities doomed by rising sea levels, calls for an overhaul of the country's agricultural system to shift crop production away from saltwater-contaminated areas, and spells out the need to shore up coastal defenses, including by restoring degraded habitat. Project Life stands out for taking a long view: It intends to prepare Cuba for climatological impacts over the next century. Much of the initial funding could come from a $100 million proposal that Cuba plans to submit soon to the Global Climate Fund.

    The Federal Government is committed to following sustainable principles. At its heart, sustainability integrates environmental, societal and economic solutions for present needs without compromising the ability of future generations to meet their needs. Building upon its pledge towards environmental stewardship, the Administration generated a vision of sustainability spanning ten goals mandated within Executive Order (EO) 13693, Planning for Federal Sustainability in the Next Decade. In November 2015, the National Aeronautics and Space Administration (NASA) responded to this EO by incorporating it into a new release of the NASA Strategic Sustainability Performance Plan (SSPP). The SSPP recognizes the importance of aligning environmental practices in a manner that preserves, enhances and strengthens NASA's ability to perform its mission indefinitely. The Kennedy Space Center (KSC) is following suit with KSC's Sustainability Plan (SP) by promoting, maintaining and pioneering green practices in all aspects of our mission. KSC's SP recognizes that the best sustainable solutions use an interdisciplinary, collaborative approach spanning civil servant and contractor personnel from across the Center. This approach relies on the participation of all employees to develop and implement sustainability endeavors connected with the following ten goals: Reduce greenhouse gas (GHG) emissions. Design, build and maintain sustainable buildings, facilities and infrastructure. Leverage clean and renewable energy. Increase water conservation. Improve fleet and vehicle efficiency and management. Purchase sustainable products and services. Minimize waste and prevent pollution. Implement performance contracts for Federal buildings. Manage electronic equipment and data centers responsibly. Pursue climate change resilience. The KSC SP details the strategies and actions that address the following objectives: Reduce Center costs. center dot Increase energy and water efficiencies.

The Commission believes that this mission must be the foundation for making decisions about what activities the agency should perform. Thus, the Commission's programmatic decisions will not be fee-driven but will be based on their contributions to public health and safety. This strategic plan establishes a strategic framework that will guide future decision-making and will help the NRC continue to meet its responsibility for protecting public health and safety, promoting the common defense and security, and protecting the environment. Meeting these responsibilities requires the collective efforts of the NRC and its licensees, since the regulatory oversight of licensees is the responsibility of the NRC and the safe and secure use of nuclear materials for civilian purposes is the responsibility of NRC licensees. Finally, the development and implementation of the strategic plan will meet the requirements of the Government Performance and Results Act

In this work the more recent discoveries on the effects in the health, the environment and economic that have been reported, as well as the current advances regarding the solution of the problems with the sarcophagus are commented. Other aspects little mentioned that consequences of the accident can be considered are discussed also, like they are the increment in the nuclear safety in the reactors in operation in the entire world and the termination of the cold war with the consequent dismantlement of a great one numbers of nuclear weapons. Finally it is remembered that the lessons learned in Chernobyl should never be forgotten. (Author)

    For most college students, lack of career planning wastes time and resources and may result in years of "career drift." Lack of planning can also lead to deception once students begin seeking career-related employment. Faced with a competitive job market, some students inflate and exaggerate their resumes. The five-year resume exercise helps…

    1989-01-01

    Airtightness tests were performed on 20 new houses over a 2-year period in Winnipeg. The houses were constructed with a variety of air/vapor barrier systems and 3 different types of main walls. Polyethylene was used as the air/vapor barrier in 6 of the houses while the remaining 14 used the airtight drywall approach (ADA). The houses had similar floor plans and were constructed by the same builder. Both the polyethylene and ADA systems were found to be capable of meeting the airtightness requirements of the R-2000 standard with the tightest structures being double wall houses. No significant or permanent change in airtightness was observed for any of the houses over the monitoring period. Application of stucco as an exterior finish was found to improve airtightness of the ADA houses, but not of the double wall houses with polyethylene vapor barriers. Consistent sources of air leakage in the ADA houses were found to be the electrical outlets on exterior walls. Window leakage was also noted in many houses and the frequency of this leakage increased over the monitoring period. A significant leakage source was found to be an integrated mechanical system, which ducted in large volumes of outdoor air. It was also concluded there is a need to re-examine the design pressure requirements for residential air barrier systems. Specifically, this should investigate how transient wind-induced pressure loads are resisted by air barrier systems and whether some portion of the load is taken by other envelope components. An air leakage detection system was proposed consisting of a simple non-instrumented blower, which would be suitable for use by builders to aid in the construction of low leakage houses. 17 refs., 10 figs., 8 tabs.

    The purpose of this mixed prospective and retrospective case series was to evaluate the long-term health-related quality of life and physical disability after in situ arthrodesis for high-grade isthmic spondylolisthesis. Thirty-five of forty consecutive patients who had in situ spinal arthrodesis for high-grade isthmic spondylolisthesis at a mean age of fifteen years (range, nine to twenty-five years) completed validated questionnaires (Short Form-36 [SF-36], EuroQol-5 Dimensions [EQ-5D], Zung depression scale, Oswestry disability index [ODI], Million score, and back and leg pain visual analog scale [VAS]) and underwent physical examination twenty-nine years (range, twenty-three to thirty-five years) after surgery. The mean age at the time of follow-up was forty-three years (range, thirty-seven to fifty-one years). In the absence of a formal control group, the scores on the SF-36 and EQ-5D were compared with Swedish normative data. The proportion of patients at work was compared with an age-matched control group derived from official statistics of Sweden. The Million score at the long-term follow-up was compared with the corresponding results at the mid-term follow-up of the same patients at a mean age of twenty-two years. The scores on the SF-36 and EQ-5D were similar to the scores of the general Swedish population. The mean Zung depression scale score was 30 (range, 20 to 52), the mean ODI score was 10 (range, 0 to 34), the mean back pain VAS score was 13 (range, 0 to 72), and the mean leg pain VAS score was 9 (range, 0 to 60). The Million score averaged 28 (range, 0 to 109) and was slightly worsened compared with the score of 19 (range, 0 to 94) at the mid-term follow-up (p = 0.034). The proportion of patients at work was the same as that for the age-matched general Swedish population. Our study shows good outcomes in health-related quality of life, disability, pain, and ability to work at up to twenty-nine years after in situ lumbar spine arthrodesis for high

In his words, he set out to "ponder the developments in the several subfields of anthropol­ogy over this period of time, as reflected in the topics selected for review in this enterprise" (p. 8. To this end Siegel, a cultural anthropologist, mined the collective knowledge contained within twenty years of the ARA. In his presentation, he considers the intellectual developments within each of the five subdisciplines separately (he includes applied anthropology, concluding with some brief remarks on the importance of maintaining a four or five field approach to anthropology. For our purposes here, I will limit my comments to his section on archaeology.

    1988-01-01

    As to the electric power facility plan in fiscal year 1988, 15 designated electric power enterprises made the notification to the Minister of International Trade and Industry in March, 1988. This outline of the facility plan summarized the plans of 66 enterprises in total, including the plans of municipally operated, joint thermal power and other enterprises in addition to the above 15. In order to ensure the stable supply of electric power, the Ministry of International Trade and Industry considers that it is indispensable to purposefully develop electric power sources and the facilities for distribution along this facility plan. The forecast for fiscal year 1997 is : total electric power demand 778.2 billion kWh, maximum power demand 151.21 million kW, and yearly load factor 56.9 %. This is equivalent to the yearly growth of 2.4 %. In fiscal year 1988, it is planned to present 29 plants of 2760 MW to the Power Source Development Coordination Council. The breakdown is : hydroelectricity 140 MW, thermal power 2010 MW, and nuclear power 610 MW. The Ministry guides electric power enterprises so as to realize the diversification of electric power sources. Also the increase of transmission and transformation facilities, the plan of equipment investment and others are reported. (Kako, I.)

    2003-04-01

    This paper presents an exploratory trend analysis of the statistics published over the past twenty-four editions of the Annual Statistics of Medical School Libraries in the United States and Canada. The analysis focuses on the small subset of nineteen consistently collected data variables (out of 656 variables collected during the history of the survey) to provide a general picture of the growth and changing dimensions of services and resources provided by academic health sciences libraries over those two and one-half decades. The paper also analyzes survey response patterns for U.S. and Canadian medical school libraries, as well as osteopathic medical school libraries surveyed since 1987. The trends show steady, but not dramatic, increases in annual means for total volumes collected, expenditures for staff, collections and other operating costs, personnel numbers and salaries, interlibrary lending and borrowing, reference questions, and service hours. However, when controlled for inflation, most categories of expenditure have just managed to stay level. The exceptions have been expenditures for staff development and travel and for collections, which have both outpaced inflation. The fill rate for interlibrary lending requests has remained steady at about 75%, but the mean ratio of items lent to items borrowed has decreased by nearly 50%.

    The incidence of stroke in Sweden increased between 1989 and 2000 among people aged ≤65 years, but more recent data on those aged >65 years are lacking. Through the Swedish Hospital Discharge and Cause of Death registries, we identified all cases of nonfatal and fatal ischemic stroke (IS) among people aged 18 to 84 years during 1987-2010 in Sweden. Of the 391 081 stroke cases identified, 1.6% were 18 to 44 years, 16.7% were 45 to 64 years, and 81.7% were 65 to 84 years. Among people aged 18 to 44 years, there was a continuous increase in the incidence of stroke of 1.3% (95% confidence interval, 0.8%-1.8%) per year for men and 1.6% (1.0%-2.3%) per year for women. Among men and women aged 45 to 64 years, slightly declining rates were observed from the late 1990s, with a mean annual decrease of 0.4% (0.1%-0.7%) among men and 0.6% (0.2%-1.0%) among women. Among men aged 65 to 84 years, a decrease of 3.7% in IS (3.4%-4.0%) per year was observed from the late 1990s. This was more marked in women, where an initial decrease of 2.5% (2.1%-2.9%) per year was followed by an accelerated decrease of 5.1% (4.4%-5.8%) after 2005. Mortality from IS decreased markedly in all age groups. The incidence of IS in elderly people in Sweden is now decreasing, whereas the decline in IS incidence in the middle-aged people is much less steep. The increasing incidence of stroke in the young, particularly if carried forward to an older age, is concerning.

    Full Text Available Management of arid ecosystems (MEZA by its Spanish acronym is a Master of Science program that started in 1990 when very few interdisciplinary programs in environmental management existed in the world. Graduates and current students recognize the importance of a group of pioneers in multidisciplinary practice who have translated the scientific findings and insights of a diverse scholarly community into practical applications within the city in which the University of Baja California, El Sauzal campus, is located and its surrounding arid and coastal rural areas. Students and teachers have produced 20 ecosystem management plans, which have trained the students in practical teamwork. Most of these plans addressed an inquiry by a local community or government decision maker, which is considered to be the key origin of a project. In this paper, the MEZA program that the teachers designed is briefly described, and a series of projects are given as examples of their work. Two projects are more thoroughly explained because all of the coauthors (2009 and 2010 students participated in these projects and believe that it is a valuable experience to share with others.

    Background The Annals of Botany is a peer-reviewed scientific journal publishing papers on a wide range of topics in plant biology. It first appeared in 1887, making it the oldest continuously published botanical title. The present article gives a historical account of events leading to the founding of the Journal and of its development over the first 50 years. Sources of Information Much of the content is drawn from the Journal’s own records and from extensive Minutes, financial accounts, personal letters and notes relating to the Annals of Botany that were repatriated from University College, University of London in 1999. Documents held at the Royal Botanic Gardens, Kew and at the Oxford University Press Museum were also consulted. Content Emphasis is placed on the individuals who instigated, edited and managed the Annals of Botany up to 1937, especially the nine founding members of the Journal and the background that brought them together and motivated them to start the Annals of Botany. A falling out between two of the founders in 1899 is highlighted since not only did this threaten the Journal’s future but also gives much insight into the personalities of those most closely involved in the Journal during its formative years. The article also examines the way the Journal was funded and how it dealt with its publisher (the University of Oxford’s Clarendon Press), turned itself into a registered company (the Annals of Botany Company) and coped with the travails of the First World War, currency inflation and the Great Depression. Plans to re-start the Journal as a New Series, beginning in 1937, are discussed in the context of the competition the Annals of Botany then faced from younger journals. PMID:25561090

    This plan covers 5 years (fiscal years 1986 through 1990) of work in the repository sealing materials program to support design decisions and licensing activities for a salt repository. The plan covers a development activity, not a research activity. There are firm deliverables as the end points of each part of the work. The major deliverables are: development plans for code development and materials testing; seal system components models; seal system performance specifications; seal materials specifications; and seal materials properties ''handbook.'' The work described in this plan is divided into three general tasks as follows: mathematical modeling; materials studies (salt, cementitious materials, and earthen materials); and large-scale testing. Each of the sections presents an overview, status, planned activities, and summary of program milestones. This plan will be the starting point for preparing the development plans described above, but is subject to change if preparation of the work plan indicates that a different approach or sequence is preferable to achieve the ultimate goal, i.e., support of design and licensing

    Full Text Available Background: In most cases, the work of medical doctors, be they general practitioners or specialists, involves some dimension of health promotion (HP. There is thus ample justification for increasing the awareness of medical students vis-à-vis HP and its relevance for their future practice.Methods: In the context of a major curriculum reform (problem-based learning [PBL] at the Faculty of Medicine of the University of Geneva in the mid-1990s, several steps were taken to strengthen HP throughout the curriculum and include HP in its key domains as defined by the Ottawa Charter (OC.Results: First, the political dimension of HP was developed in a series of first- and fifth-year lectures and third-year workshops; second, community action was strengthened through a third year one-month community immersion program; third, the development of personal skills was integrated into second- and third-year PBL cases and into fourth-and fifth-year learning activities in clinical settings as well as second- and third-year HP electives; in terms of reorienting health services, the chosen approach included the development of a HP-specific track in the context of a Certificate of Advanced Studies (CAS in Community Health and a Master of Advanced Studies(MAS in Public Health. Furthermore, a supportive intra-university environment was created through a collaborative convention with Health Promotion Switzerland, which is in charge of coordinating HP in Switzerland.Conclusion: In our view, HP teaching for medical students seems all the more relevant given that future medical doctors will have to take care of an increasing number of patients likely to develop chronic non-communicable diseases.

    "The essay analyzes the immigration policy pursued by Sweden from 1966, the year in which the first commission was established for this particular area, till 1985, the year in which an important reform was passed regarding the reception of refugees. The focal point of this immigration policy is singled out halfway in the 70's when the assimilation model is repudiated in favor of multiculturalism. One of the main features of this policy is the priority role accorded to research. The author examines the main fields of interest pursued by researchers, in particular the more recent studies on the ethnic-cultural dimension of the immigration phenomenon."

    Background Firearm-related deaths are a serious public-health problem in South Africa, which has the second-highest rate of firearm-related deaths in the world. Objective The aim of this study was to examine the trend in firearm deaths in the Transkei subregion of South Africa. Method An autopsy record review study was conducted at the Forensic Pathology Laboratory at Mthatha over a period of 23 years (1993-2015). Results Over a 23-year period (1993-2015), 27,036 autopsies were performed at the Mthatha Forensic Pathology Laboratory on people who had died from unnatural causes. Of these, 3935 (14.2%) deaths were related to firearm injuries. The average gunshot death rate during the study period was 29/100,000 of the population annually. The majority (3236; 82%) were males, among whom the death rate was 24.4/100,000 of the population per year. The rate of gunshot deaths was 27/100,000 of the population in 1993, while in 2015 it was 12.8/100,000. About a third (1207; 31%) of victims were between 21 and 30 years of age. Conclusion The gunshot death rate is at an unacceptably high level in the Transkei subregion of South Africa, especially among young people.

    Full Text Available The Nakhodka, a Russian tanker loaded with 19,000 kL of C-type heavy oil, was broken up into sections and submerged off Oki Island, Shimane Prefecture, Japan on 2 January 1997. The bow, after drifting for four days, was wrecked off Anto, Sakai City (Mikuni, Fukui Prefecture, threatening the environment throughout the various shores of Ishikawa Prefecture. The accident, caused by a heavy oil spill of 6200 kL, created serious environmental problems along the shores of Hokuriku District. We report the characterization of C-type heavy oil 20 years after the accident at the Atake seashore, Wajima City, Ishikawa Prefecture, in the Sea of Japan, based on observations in the field on 18 January 2017. We studied the microstructure, mineralogy, chemical composition, and radioactivity associated with microorganisms in the soils, and buried fishing nets and ropes that were contaminated with C-type heavy oil from this spill. The analyses used a combination of micro techniques, analytical data based on a CHN analyzer, X-ray powder diffraction (XRD, and two kinds of scanning electron microscopy equipped with energy dispersive spectroscopy (SEM-EDS. Hydrocarbon-degrading bacteria, paraffin wax, cristobalite, graphite, calcite, halite, and biotite from the Nakhodka oil spill were recognized on the surface of ropes and in the soil of the polluted seashores after 20 years. The chemical compositions indicated that high concentrations of C, O, Na, Al, Si, P, S, Ca, Fe, Cl, Sr, and Pb were predominantly indigenous to the Nakhodka oil spill. In the XRD analysis of the oil-contaminated soils on the rope at the Atake seashore indicated paraffin wax, graphite, sulfate, calcite and halite refractions with clay minerals, after 20 years. To date, no report has described the results of electron microscopy observations, such as Micrococcus bacillus and filamentous fungi, found in oil-contaminated soils after 20 years. In this research, such observations are introduced as

    The impact of human activities on the health of the population and of the wider environment has prompted action to monitor the presence of toxic compounds in the atmosphere. Toxic organic micropollutants (TOMPs) are some of the most insidious and persistent of these pollutants. Since 1991 the United Kingdom has operated nationwide air quality networks to assess the presence of TOMPs, including polycyclic aromatic hydrocarbons (PAHs), in ambient air. The data produced in 2010 marked 20 years of nationwide PAH monitoring. This paper marks this milestone by providing a novel and critical review of the data produced since nationwide monitoring began up to the end of 2011 (the latest year for which published data is available), discussing how the networks performing this monitoring has evolved, and elucidating trends in the concentrations of the PAHs measured. The current challenges in the area and a forward look to the future of air quality monitoring for PAHs are also discussed briefly.

    Disturbance shapes plant communities over a wide variety of spatial and temporal scales. How natural and anthropogenic disturbance interact to shape ecological communities is highly variable and begs a greater understanding. We used five censuses spanning the years 1990–2011 from the 16-ha Luquillo Forest Dynamics Plot (LFDP) in northeast Puerto Rico to investigate the interplay of human land-use legacies dating to the early 20th century and two recent hurricanes (Hugo, 1989 and Georges, 1998...

    2016-10-01

    Hallucinations are a salient feature of both psychotic and mood disorders. Currently there is a call for more research on the phenomenology of different forms of hallucinations, in a broader array of disorders, to further both theoretical knowledge and clinical utility. We investigated auditory, visual, and olfactory hallucinations at index hospitalization and auditory and visual hallucinations prospectively for 20years in 150 young patients, namely 51 schizophrenia, 25 schizoaffective, 28 bipolar, and 79 unipolar depression. For the index hospitalization, the data showed schizophrenia and schizoaffective patients had a greater rate of auditory and visual hallucinations than bipolar and depression patients. However, over the longitudinal trajectory of their illness, a greater percentage of schizophrenia patients had auditory and visual hallucinations than schizoaffective patients, as well as bipolar and depression patients. Also, in contrast to the initial period, schizoaffective patients did not differentiate themselves over the follow-up period from bipolar patients. Bipolar and depression patients did not significantly differ at index hospitalization or at follow-up. We found visual hallucinations differentiated the groups to a greater degree over the 20year course than did auditory hallucinations. These findings suggest the longitudinal course is more important for differentiating schizophrenia and schizoaffective disorder, whereas the initial years may be more useful to differentiate schizoaffective disorder from bipolar disorder. Furthermore, we found that the early presence of auditory hallucinations was associated with a reduced likelihood for a future period of recovery. No olfactory hallucinations were present at the index hospitalization in any patients. Over the course of 20years, a minority of schizophrenia patients presented with olfactory hallucinations, and very few schizoaffective and bipolar patients presented with olfactory hallucinations.

    Full Text Available BACKGROUND: Few studies have formally assessed whether treatment outcomes have improved substantially over the years for patients with extensive disease small-cell lung cancer (ED-SCLC enrolled in phase III trials. The objective of the current investigation was to determine the time trends in outcomes for the patients in those trials. METHODS AND FINDINGS: We searched for trials that were reported between January 1981 and August 2008. Phase III randomized controlled trials were eligible if they compared first-line, systemic chemotherapy for ED-SCLC. Data were evaluated by using a linear regression analysis. RESULTS: In total, 52 trials were identified that had been initiated between 1980 and 2006; these studies involved 10,262 patients with 110 chemotherapy arms. The number of randomized patients and the proportion of patients with good performance status (PS increased over time. Cisplatin-based regimens, especially cisplatin and etoposide (PE regimen, have increasingly been studied, whereas cyclophosphamide, doxorubicin, and vincristine-based regimens have been less investigated. Multiple regression analysis showed no significant improvement in survival over the years. Additionally, the use of a PE regimen did not affect survival, whereas the proportion of patients with good PS and the trial design of assigning prophylactic cranial irradiation were significantly associated with favorable outcome. CONCLUSIONS AND SIGNIFICANCE: The survival of patients with ED-SCLC enrolled in phase III trials did not improve significantly over the years, suggesting the need for further development of novel targets, newer agents, and comprehensive patient care.

  4. Environmental restoration and waste management five year plan, fiscal years 1994--1998

    International Nuclear Information System (INIS)

    1993-01-01

    In March 1989, Secretary of Energy James D. Watkins outlined his vision for a changed Department of Energy (DOE) culture. This culture is one of envirorunental responsibility, increased knowledge and involvement in environmental management, a new openness to public input, and overall accountability to the Nation for its actions. Secretary Watkins also requested all the near-term activities necessary to bring DOEactivities into compliance with all applicable environmental requirements to be detailed in one plan. The Five-Year Plan was to be based on a ''bottom up'' approach to planning by using Activity Data Sheets to collect financial and technical information at the installation level. Over the past three years, the Five-Year Plan has evolved into the primary planning tool for the DOE Environmental Restoration and Waste Management Program, looking beyond the current three-year Federal budget horizon. The FY 1994--1998 Five-Year Plan demonstrates DOE's commitment to a culture based on the principles of openness, responsiveness, and accountability; reports on the progress made in carrying out DOE's environmental mission; identifies what must be accomplished during a five-year planning period; and describes strategies for achieving critical program objectives. This plan represents another step towards the implementation of the culture change Secretary Watkins envisioned. The Five-Year Plan is not exclusively focused on near-term activities. Italso expresses the DOE commitment to a 30-year goal for the cleanup of the 1989 inventory of inactive sites. The FY 1994--1998 Five-Year Plan reiterates the DOE commitment to meeting this and other important environmental goals

    Review the authors' institutional experience of the induction and perioperative airway management of children with tetralogy of Fallot with an absent pulmonary valve. Retrospective chart review. Large academic children's hospital. Patients with the diagnosis of tetralogy of Fallot with absent pulmonary valve undergoing primary cardiac repair over a 20-year period. None. Forty-four patients were identified with tetralogy of Fallot with an absent pulmonary valve from January 1995 through August 2014. Forty-two patients (95%) required surgery in their first year of life. Sixteen patients (36%) required mechanical ventilation preoperatively, including 11 neonates. Of the 28 patients not intubated preoperatively, only 1 (3.8%) exhibited minor airway obstruction following induction that was managed uneventfully. All intubations in the operating room were performed in the supine position. Five patients who were mechanically ventilated preoperatively in a lateral or prone position were supinated in the operating room without significant cardiopulmonary compromise. There were no patients who suffered cardiopulmonary arrest or required mechanical circulatory support. The median time to extubation was 2 days (range 1-13 days) in those patients who were not mechanically ventilated prior to their surgery. Ultimately, 5 patients required tracheostomy and 1 patient underwent lobectomy. Although, there was no mortality at 30 days, 4 children died within 1 year of their surgery. All the children who died had a genetic syndrome and required mechanical ventilation preoperatively. While there are theoretical concerns specific to the induction and airway management of tetralogy of Fallot with an absent pulmonary valve, there were no episodes of cardiorespiratory arrest or extracorporeal membrane oxygenation in the authors' series. Neonatal age at the time of surgery, preoperative need for mechanical ventilation, and concomitant genetic syndromes are risk factors for respiratory

    The natural history of Fanconi anemia remains hard to establish because of its rarity and its heterogeneous clinical presentation; since 1994, the Italian Fanconi Anemia Registry has collected clinical, epidemiological and genetic data of Italian Fanconi Anemia patients. This registry includes 180 patients with a confirmed diagnosis of Fanconi anemia who have either been enrolled prospectively, at diagnosis, or later on. After enrollment, follow-up data were periodically collected to assess the clinical course, possible complications and long-term survival; the median follow up was 15.6 years. The main goal of the study was to describe the natural history of Fanconi anemia, focusing on the following variables: family history, disease presentation, development of hematological manifestations, development of malignancies, occurrence of hematopoietic stem cell transplantation and survival. Typical morphological and/or hematological abnormalities and/or growth retardation were the most common manifestations at diagnosis; the majority of patients (77%) exhibited hematological abnormalities at the initial presentation, and almost all (96%) eventually developed hematological manifestations. More than half of the patients (57%) underwent a bone-marrow transplant. The occurrence of cancer was quite rare at diagnosis, whereas the cumulative incidence of malignancies at 10, 20 and 30 years was 5%, 8% and 22%, respectively, for hematological cancers and 1%, 15% and 32%, respectively, for solid tumors. Overall survival at 10, 20 and 30 years were 88%, 56% and 37%, respectively; the main causes of death were cancer, complications of the hematological presentation and complications of transplantation. These data clearly confirm the detrimental outcome of Fanconi anemia, with no major improvement in the past decades. Copyright© Ferrata Storti Foundation.

    Background Transkei is regarded as a rural part of South Africa. It was one of the black homelands where rigorous apartheid was practised. The incidence of firearm-related deaths used to be very high, but after the implementation of the Firearm Control Act in 2002, the trend changed. However, the murder rate is still a major public-health problem in this region of South Africa. Objective The aim of this study was to investigate 23 years (1993-2015) of homicide trends in the Transkei region of South Africa. Method A review of records of medico-legal autopsies performed at Mthatha Forensic Pathology Laboratory from 1993 to 2015 was undertaken. Results Between 1993 and 2015, the number of autopsies performed on people who had died unnatural deaths was 24,693. The records of 12,618 (51%) autopsies on victims of homicide between 1993 and 2015 were available for study. The average rate of murder was 85/100,000 of the population in this region. Of these deaths, on average 34/100,000 were caused by sharp-edged instruments, 30/100,000 by gunshot wounds and 21/100,000 by blunt trauma. The rate of murder of males was significantly higher than that of females, with a ratio of 5.7:1, and over the period of 23 years covered by this study, the incidence was highest (30.5/100,000) in the young age group between 21 and 30 years. Conclusion The rate of homicide is very high in the Transkei region of South Africa. It needs urgent intervention to curb unnecessary deaths.

    Efforts to implement family cord blood banking have been developed in the past decades for siblings requiring stem cell transplantation for conditions such as sickle cell disease. However, public banks are faced with challenging decisions about the units to be stored, discarded, or used for other endeavors. We report here 20 years of experience in family cord blood banking for sickle cell disease in two dedicated public banks. Participants were pregnant women who had a previous child diagnosed with homozygous sickle cell disease. Participation was voluntary and free of charge. All mothers underwent mandatory serological screening. Cord blood units were collected in different hospitals, but processed and stored in two public banks. A total of 338 units were stored for 302 families. Median recipient age was six years (11 months-15 years). Median collected volume and total nucleated cell count were 91 mL (range 23-230) and 8.6×10 8 (range 0.7-75×10 8 ), respectively. Microbial contamination was observed in 3.5% (n=12), positive hepatitis B serology in 25% (n=84), and homozygous sickle cell disease in 11% (n=37) of the collections. Forty-four units were HLA-identical to the intended recipient, and 28 units were released for transplantation either alone (n=23) or in combination with the bone marrow from the same donor (n=5), reflecting a utilization rate of 8%. Engraftment rate was 96% with 100% survival. Family cord blood banking yields good quality units for sibling transplantation. More comprehensive banking based on close collaboration among banks, clinical and transplant teams is recommended to optimize the use of these units. Copyright© Ferrata Storti Foundation.

    1980-01-01

    In March 1954, radioactive debris from a thermonuclear weapon test at Bikini Atoll deviated from predicted trajectories and contaminated several atolls in the northern Marshall Islands. As a result, 239 native inhabitants of these islands along with 28 American servicemen and 23 Japanese fishermen received variably severe exposures to diverse ionizing radiations. Fallout material consisted largely of mixed fission products with small amounts of neutron-induced radionuclides and minimal amounts of fissionable elements, producing a complex spectrum of electromagnetic and particulate radiation. Individuals were exposed to deeply penetrating, whole-body gamma irradiation, to internal radiation emitters assimilated either by inhalation or by ingestion of contaminated water and food, and to direct radiation from material accumulating on body surfaces. That accident initiated a cascade of events, medical, social and political, which continue in varying forms to this day. Most of these have been discussed in the open medical literature and in periodic reports issued by the medical team headquartered at Brookhaven National Laboratory. This report attempts to summarize some of the principal findings of medical significnce that have been observed during the subsequent 26 years with particular emphasis on the last six years

    In 1983 Finland became the second country in the world, after Sweden, to adopt a law prohibiting all kinds of physical punishment towards children, also by parents. The present investigation was carried out in 2011, 28 years after the law was adopted. Changes in exposure to various types of physical punishment towards respondents born between 1931 and 1996 are presented. A representative sample from Western Finland, consisting of 4,609 respondents (2,632 females, 1,977 males) between 15 and 80 years, filled in a paper-and-pencil questionnaire. A number of psychosocial concomitants were measured. The results showed a significant drop in reports of being slapped and beaten with an object among respondents who were born after the law was adopted. The decline in physical punishment was associated with a similar decline in the number of murdered children. Respondents who had been exposed to higher amounts of physical punishment than average scored significantly higher on alcohol abuse, depression, mental health problems, and schizotypal personality. Divorced respondents had been significantly more physically punished than others. Respondents who had attempted suicide during the last 12 months had been exposed to physical punishment during childhood significantly more often than those who had not attempted suicide. © 2014 Wiley Periodicals, Inc.

    In this study, we investigated at the genome-wide level if 20 years of artificial directional selection based on boar genetic evaluation obtained with a classical BLUP animal model shaped the genome of the Italian Large White pig breed. The most influential boars of this breed (n = 192), born from 1992 (the beginning of the selection program of this breed) to 2012, with an estimated breeding value reliability of >0.85, were genotyped with the Illumina Porcine SNP60 BeadChip. After grouping the boars in eight classes according to their year of birth, filtered single nucleotide polymorphisms (SNPs) were used to evaluate the effects of time on genotype frequency changes using multinomial logistic regression models. Of these markers, 493 had a PBonferroni  selection program. The obtained results indicated that the genome of the Italian Large White pigs was shaped by a directional selection program derived by the application of methodologies assuming the infinitesimal model that captured a continuous trend of allele frequency changes in the boar population. © 2015 Stichting International Foundation for Animal Genetics.

    Chemotherapy (Cht) for rhabdomyosarcoma (RMS) given before local treatment can prevent mutilating surgery and high-dose irradiation (RT). Fine needle aspiration biopsy (FNAB) can confirm the diagnosis and neoadjuvant treatment can start without delay. The purpose of our study was to assess the role of FNAB in the management of childhood RMS in Slovenia. A total of 78 children and young adults were included. FNAB provided the pre-treatment diagnosis in 37 and surgical biopsy in 41 patients. In 61 cases recurrent/metastatic disease was aspirated. Cytological diagnoses were compared to the original histological diagnoses. All case histories, cytological and histological material were reviewed and immunocytochemical staining performed when necessary. FNAB provided a correct diagnosis of malignancy in all 37 primary tumours, a specific diagnosis of RMS was given in 29 (78%). With the use of immunocytochemistry during the last 15 years, the accuracy has risen to 87%. FNAB provided the diagnosis of recurrence/metastasis in 57/61 cases. No complications of FNAB were noted. Review of histology reclassified five original diagnoses of RMS into one malignant rhabdoid tumour and four sarcomas NOS. In review of cytology we were able to sub classify 80% of RMS. FNAB is a safe method, which enables us to establish the pre-treatment diagnosis of RMS, and to some extent even its type, without delay. In our study, FNAB successfully replaced surgical biopsy in 87% of RMS patients during the last 15 years. Neoadjuvant Cht was started immediately, surgery was delayed and more conservative. Consequently, the risk for treatment sequelae was considerably reduced. Copyright 2002 Wiley-Liss, Inc.

    This paper describes a model for multi-year transmission network expansion to be used in long-term system planning. The network is represented by a linearized (DC) power flow and, for each year, operation costs are evaluated by a linear programming (LP) based algorithm that provides sensitivity indices for circuit reinforcements. A Backward/Forward approaches is proposed to devise an expansion plan over the study period. A case study with the southeastern Brazilian system is presented and discussed.

    2006-04-01

    Airborne effluents of 5 stacks (stacks 1-5) of three nuclear power plants, with 9 pressurized water reactors VVER of 4,520 MWe total power, were searched for transuranium isotopes in different time periods. The search started in 1985. The subject of this work is a presentation of discharge data for the period of 1998-2003 and a final evaluation. It was found that 238Pu, 239,240Pu, 241Am, 242Cm, and 244Cm can be present in airborne effluents. Transuranium isotope contents in most of the quarterly effluent samples from stacks 2, 4 and 5 were not measurable. Transuranium isotopes were present in the effluents from stack l during all 9 years of the study and from stack 3 since the 3rd quarter of 1996 as a result of a defect in the fuel cladding. A relatively high increase of transuranium isotopes in effluents from stack 3 occurred in the 3rd quarter of 1999, and a smaller increase occurred in the 3rd quarter of 2003. In each instance 242Cm prevailed in the transuranium isotope mixtures. 238Pu/239,240Pu, 241Am/239,240Pu, 242Cm/239,240Pu, and 244Cm/239,240Pu ratios in fuel for different burn-up were calculated, and comparison of these ratios in fuel and effluents was performed.

  1. Vingt ans après (Twenty years after). Comment on "Disentangling DNA molecules" by Alexander Vologodskii

    Grosberg, Alexander Y.

    2016-09-01

    The effect of DNA topology simplification by type II topoisomerase enzymes was discovered experimentally by Rybenkov et al. [1] 20 years ago - which motivates me to borrow the title for this comment from Alexandre Dumas [2]. Ever since the original discovery, the effect keeps entertaining theorists - but the most surprising fact is that the original experiment was never repeated, let alone improved. I do not understand why it is so. In my opinion, there is an acute need of new experiments, not only repeating the original measurements, but also examining numerous other aspects of the phenomenon. In this sense, the review [3] by Vologodskii, one of the original discoverers, is both timely and important. In his review, Vologodskii concentrates on what I would call mechanical aspect of the problem - how bent are T- and G-segments, what kinds of juxtaposition are relevant, etc. The importance of these issues notwithstanding, I want to complement this approach, and to consider in greater detail the thermodynamics of the process. My main points are as follows: action of topo II enzyme violates detailed balance for DNA, leading to circular currents and dissipation (which is indeed quite a common occurrence in many living systems). These currents are potentially observable, and dissipation measurable, which should challenge experimenters. The main goal of this comment is to show how general phenomenological point of view allows to formulate theoretical prediction for the energy dissipation rate.

  2. Twenty years of Internet-based research at SCiP: A discussion of surviving concepts and new methodologies.

    This discussion of the symposium 20 Years of Internet-Based Research at SCiP: Surviving Concepts, New Methodologies compares the issues faced by the pioneering Internet-based psychology researchers who presented at the first symposia on the topic, at the 1996 annual meeting of the Society for Computers in Psychology, to the issues facing researchers today. New methodologies unavailable in the early days of Web-based psychological research are discussed, with an emphasis on mobile computing with smartphones that is capitalizing on capabilities such as touch screens and gyro sensors. A persistent issue spanning the decades has been the challenge of conducting scientific research with consumer-grade electronics. In the 1996 symposia on Internet-based research, four advantages were identified: easy access to a geographically unlimited subject population, including subjects from very specific and previously inaccessible target populations; bringing the experiment to the subject; high statistical power through large sample size; and reduced cost. In retrospect, it appears that Internet-based research has largely lived up to this early promise-with the possible exception of sample size, since the public demand for controlled psychology experiments has not always been greater than the supply offered by researchers. There are many reasons for optimism about the future of Internet-based research. However, unless courses and textbooks on psychological research methods begin to give Web-based research the attention it deserves, the future of Internet-based psychological research will remain in doubt.

    The purpose of the study was to evaluate our experience with enteric duplication cysts in 40 children during the past 26 years, while assessing the variability of their presentations and to propose an algorithm for surgical management. We retrospectively analysed sex, age, clinical presentations, duplication site, surgical treatment, presence of ectopic tissue, complications, associated anomalies, and prognosis of 40 patients with gastrointestinal tract duplications who were surgically treated in our clinic. Overall, there was a predominance of boys (28 males, 70 %; 12 females, 30 %). The presenting symptom was vomiting in 23 patients, rectal bleeding in 11 patients, abdominal mass in 10 patients, abdominal pain in 9 patients, constipation in 6 patients, cough in 2 patients, and respiratory distress in 2 patients. In 30 patients, a complete excision of the cyst with additional segmental intestinal resection and anastomosis was performed. Cystectomy was performed in seven patients, while complete excision of the cyst with additional wedge resection was performed in two. A Wrenn procedure (mucosectomy) was performed in one patient. Due to the variability in the site of enteric duplications, a wide range of presenting symptoms can exist, which is challenging for diagnosis. In children with a diagnosis of acute abdomen, enteric duplication cysts should be considered, and these children should be further investigated for additional skeletal, urogenital, and gastrointestinal system pathologies. Surgical treatment depends on the site and type of the cyst.

    A survey of the transport of spent fuel in and from Germany during the last 20 years is presented. The spent fuel is now transported from the German nuclear power facilities to the reprocessing plants in France and the United Kingdom. In the past, there were also shipments to the former reprocessing plant WAK Karlsruhe (Germany), to the long-term storage facility CLAB (Sweden) and also from the former German Democratic Republic to the USSR. The transport of the spent fuel is carried out in specially built flasks requiring an extensive quality assurance programme. Due to the heavy weight of these packages, the shipments are mostly carried out by rail, but also by road and sea. An overview is given of the following matters: (i) quantities of spent fuel transport, (ii) organisation of transport (iii) licensing matters, and (iv) reported incidents. In addition, an analysis is included of the radiation exposure for normal conditions of transport, especially of the transport workers. Difficulties and hindrances during transport are also reported.

    The aim of the study was to analyse associations of religiosity and mortality in a secular region. The sample consisted of 734 Danish, community dwelling elderly persons, living in a secular culture, and all aged 70 when primary data were collected. Secondary data consisted of a 20 year follow-up on vital status or exact age of death. The study was designed to be highly comparable to studies conducted in more religious environments in order to compare results. Three variables of religion were investigated in relation to survival: importance of affiliation, church attendance and listening to religious media. Relative hazards (RH) of dying were controlled in models including gender, education, medical and mental health, social relations, help given and received, and health behaviour. The results showed significant and positive associations between claiming religious affiliation important and survival (relative hazard of dying=RH .70; 95% CI .58-.85) and church attendance and survival (RH .73; 95% CI .64-.87). Results decreased and only stayed significant regarding church attendance when controlled for covariates. Nearly all significant effects were seen in women, but not in men. The effect size of the full sample is less than in more religious environments in United States samples. Although the positive overall RHs are comparable to those of other studies, the mediating variables and pathways of effects seem dissimilar in this sample from a secular environment. Receiving and especially giving help to others are suggested as variables of explanatory value.

    To analyze the trend in socioeconomic inequalities in all-cause mortality in Barcelona from 1983 to 2004. We performed an ecological study of trends over 4 cross-sections (1983-1988, 1989-1994, 1995-1999 and 2000-2004), with the basic health area (BHA) as the unit of analysis. The study population consisted of men and women aged 20 years or more living in Barcelona. The information sources were the mortality registry, the municipal census and the census of inhabitants and dwellings. The age- and sex-specific mortality rate (ASMR) for all causes was used as the dependent variable. As the independent variable, a composite index of socioeconomic deprivation of the BHA was calculated; BHAs were grouped in quartiles according to the values on the index. Poisson models were adjusted to estimate the relative risk of mortality from all causes in the 4 groups of BHA, stratified by age groups and sex. In all the study periods, inequalities in mortality were found, depending on the BHA of residence, both for men and for women: the ASMR of the most deprived BHAs were greater than those of less deprived BHA, and were greater among men than among women. Likewise, relative risks in the youngest age groups were higher than in the oldest age groups. However, from the second to fourth study periods, inequalities decreased in absolute and relative terms, especially among men. Inequalities in mortality persist in BHA in Barcelona but have decreased over the last 2 decades. Public policies should take this information into account when tackling inequalities among BHA.

    2015-02-01

    Full Text Available The Tropical Mockingbird Mimus gilvus (Vieillot, 1808 is a widespread species in the Neotropics, but its southernmost populations in Brazil are ecologically (and possibly taxonomically distinct, occurring only along the coast in restinga vegetation. Once considered the most common bird in restinga, it is becoming increasingly rare, likely due to habitat loss and illegal capture of nestlings. We conducted field surveys to provide an up-to-date distribution of the Tropical Mockingbird in the southernmost portion of the species' range, in the state of Rio de Janeiro, supplying an estimate of its current regional population size and conservation status. We surveyed 21 restinga remnants in Rio de Janeiro, covering all major restinga areas in the state. For sites where the species' presence was confirmed through transect line surveys, we estimated the local population size. The species was found at only four sites. The mean local population density was 52 individuals per km-2. The estimated current and historical Extent of Occurrence (EOO were 256 km2 and 653 km2, respectively. Combining the population size and EOO results, we estimated that the population of the state of Rio de Janeiro currently ranges from 2,662 to 13,312 individuals, corresponding to an estimated reduction of 61% to 92% in population size in the last 20 years. The species, therefore, can be considered "Endangered" in the state of Rio de Janeiro. We recommend that a taxonomic study of the southernmost populations is carried out in order to clarify whether they represent a different, likely threatened species. We also recommend that the environmental regulations that protect restingas are used towards the protection of these populations.

    In the last years the European Union has decided to specifically include nickel, cadmium, plumb and TBT in its list of priority substances in water. Trace metals pose a significant threat to organisms because above threshold availability, act as enzyme inhibitors resulting in adverse ecological effects to sediment-associated biota (e.g. macrophytes, benthos, demersal fish) and to higher-biota (e.g. pelagic fish and aquatic birds). Since 2003 International Maritime Organization called for a ban of the application of tributyltin-based paints. Wide distribution, high hydrophobicity, and persistence of organotin compounds have raised concern about their bioaccumulation, their potential biomagnification in the food webs, and their adverse effects to human health and environment, particularly most recent reviews focuses on possible endocrine disrupting effects of OT's (Galloway, 2006; Nakanishi, 2007; Takahashi et al., 1999; Veltman et al., 2006). Saltmarshes are highly heterogeneous environments that have been suffered pressures by the increasing urbanization and industrialization in the adjacent areas. Saltmarsh sediments integrate inputs of contaminants, like metals and organotin compounds and may act as long-term sources of contaminants. At the Ria Formosa saltmarsh several activities were responsible for long-term contaminants, some of them considered priority substances. This work aims to provide information about the present levels and temporal evolution in the last decades of metals (Mn, Zn, Cu, Cr, Ni, Pb, Mo, Cd and Ag, in addition to Fe and Al) and butyltins (TBT, DBT and MBT) in saltmarsh sediments at south of Portugal. Metals were analysed by atomic absorption spectrometry-AAS. Butyltins were determined, after derivatization, by solid phase micro extraction combined with gas chromatography with mass spectrometry (MS/MS). Results showed that legislation was an effective instrument for the decreasing of contamination levels, to sustainable values to ecosystem

  9. Twenty-five years of Brown Boveri experience in development, design and fabrication of circulators for HTGR

    The two circulators for the AVR experimental reactor in Juelich, Federal Republic of Germany, were supplied. The circulators, which are equipped with oil bearings, have been operating troublefree since the start of commissioning in 1966. As a consequence of a water ingress into the reactor resulting from a steam generator damage one bearing was replaced in 1977 after 72,000 operating hours. Up to the present date, each of the circulators has scored 115,000 hours of operation, one of them without any disassembly. In the THTR 300 in Schmehausen, Federal Republic of Germany, 6 BBC circulators are in operation. The insertable circulator units equipped with oil bearings have successfully proven their operating capability without any problems during the commissioning phase and the 100% power operation which was started recently. Currently active magnetic bearings are being developed for advanced gas-cooled reactors such as the HTR 100, the HTR 500 and the heating reactor after excellent results have been furnished by a small prototype in a test loop. This ADI circulator has since scored more than 15,000 operating hours without any trouble. A retainer bearing test stand also equipped with active magnetic bearings has been in operation for nearly 2 years. This test stand serves for developing the conditions for safe rundown of the rotors of even the largest circulators after the magnetic bearings have been deenergized unintentionally. Development work is conducted on the prototype of a safety-relevant circulator held in magnetic bearings, to be used for decay heat removal in the HTR 500. The original aim to have circulators without auxiliary medium for bearing lubrication will thus be reached. The advantages to be obtained in process and systems design are a supplementary support to the inherent safety characteristics of high-temperature reactors. Another advantage of these bearings is cost reduction. 5 refs, 7 figs

    Musculoskeletal allografts are now commonly used. To decrease the potential risks of transmission of pathogenic bacteria, fungi, or viruses to the transplant recipients, certain issues regarding the management of patients who receive contaminated allografts need to be addressed. We aimed to clarify the incidence and extent of disease transmission from allografts by analyzing the allografting procedures performed in the bone bank of our hospital over the past 20 years. We retrospectively reviewed the data from our allograft registry center on 3979 allografts that were implanted in 3193 recipients throughout a period of two decades, from July 1991 to June 2011. The source of the allografts, results of all screening tests, dates of harvesting and implantation, and recipients of all allografts were checked. With the help of the Center for Infection Control of our hospital, a strict prospective, hospital-wide, on-site surveillance was conducted, and every patient with healthcare-associated infection was identified. Fisher's exact test was used to compare the infection rate between recipients with sterile allografts and those with contaminated allografts. The overall discard and infection rates were, respectively, 23% and 1.3% in the first decade (1991-2001); and 18.4% and 1.25% in the second decade (2001-2011). The infection rate of contaminated allograft recipients was significantly higher than that of sterile allograft recipients (10% vs. 1.15%, P bank are comparable with those of international bone banks. Strict allograft processing and adequate prophylactic use of antibiotics are critical to prevent infection and disease transmission in such cases.

  12. Environmental restoration and waste management five-year plan, Fiscal years 1994--1998

    International Nuclear Information System (INIS)

    1993-01-01

    In March 1989, Secretary of Energy James D. Watkins outlined his vision for a changed Department of Energy (DOE) culture. This culture is one of environmental responsibility, increased knowledge and involvement in environmental management, a new openness to public input, and overall accountability to the Nation for its actions. Over the past three years, the Five Year Plan has evolved into the primary planning tool for the DOE Environmental Restoration and Waste Management Program, looking beyond the current three-year Federal budget horizon. The FY 1994--1998 Five-Year Plan demonstrates DOE's commitment to a culture based on the principles of openness, responsiveness, and accountability; reports on the progress made in carrying out DOE's environmental mission; identifies what must be accomplished during a five-year planning period; and describes strategies for achieving critical program objectives. The Five-Year Plan is not exclusively focused on near-term activities. It also expresses the DOE commitment to a 30-year goal for the cleanup of the 1989 inventory of inactive sites. This goal was established in response to recommendations from the State and Tribal Government Working Group (STGWG) that DOE define a specific end point for completing necessary remediation and restoration activities. The FY 1994--1998 Five-Year Plan reiterates the DOE commitment to meeting this and other important environmental goals

    1976-01-01

    A survey is presented of the most important results of scientific research efforts of the Nuclear Research Institute (UJV) attained in the 20 years of the Institute's existence. In 1975 the proportion of the individual fields of research was as follows: reactor technology 37%, reactor materials 19%, nuclear fuel processing including waste processing 18%, ionizing radiation applications 16%, others 10%. In the field of reactor technology, orientation is evident to light-water and fast reactors (1975): light-water reactors 40%, fast reactors 44%, heavy-water reactors 16%. The most significant contribution of the Institute to the first Czechoslovak nuclear power plant A-1 in the past period included the construction of the TR-0 heavy-water critical assembly, the choice of suitable uranium alloys and their thermal and mechanical treatment for the A-1 fuel elements, corrosion and mechanical stability study of cladding materials and post-irradiation fuel study performed in the UJV hot chambers. Significant for the development of light-water reactors are mainly the study of water regimes of radiation-exposed circuits, the solution of primary circuit chemical problems, participation in the international research programme of the CMEA countries related to the ZR-6 (Budapest) critical assembly, and the study of Zr-based cladding materials. UJV is the main Czechoslovak study centre for the development of a fast reactor and its staff have written a number of programmes for the computation of such a reactor and its fuel cycle. Also available is a suitable experimental facility. The Institute also participates in the research of UO 2 -based ceramic fuel, and in the field of spent fuel and radioactive waste processing in the development of extraction processes and the application of fluoride technology. As for ionizing radiation applications, UJV has since 1960 been manufacturing radioactive preparations including, to a limited extent, radiopharmaceuticals. It is envisaged that

    Disturbance and succession have long been of interest in ecology, but how landscape patterns of ecosystem structure and function evolve following large disturbances is poorly understood. After nearly 25 years, lodgepole pine (Pinus contorta var. latifolia) forests that regenerated after the 1988 Yellowstone Fires (Wyoming, USA) offer a prime opportunity to track the fate of disturbance-created heterogeneity in stand structure and function in a wilderness setting. In 2012, we resampled 72 permanent plots to ask (1) How have postfire stand structure and function changed between 11 and 24 yr postfire, and what variables explain these patterns and changes? (2) How has landscape-level (among-stand) variability in postfire stand structure and function changed between 11 and 24 yr postfire? We expected to see evidence of convergence beginning to emerge, but also that initial postfire stem density would still determine trajectories of biomass accumulation. After 24 yr, postfire lodgepole pine density remained very high (mean = 21,738 stems/ha, range = 0-344,067 stems/ha). Stem density increased in most plots between 11 and 24 yr postfire, but declined sharply where 11-yr-postfire stem density was > 72,000 stems/ha. Stems were small in high-density stands, but stand-level lodgepole pine leaf area, foliage biomass, and live aboveground biomass increased over time and with increasing stem density. After 24 yr, mean annual lodgepole pine aboveground net primary production (ANPP) was high (mean = 5 Mg · ha⁻¹ · yr⁻¹, range = 0-16.5 Mg · ha⁻¹ · yr⁻¹). Among stands, lodgepole pine ANPP increased with stem density, which explained 69% of the variation; another 8% of the variation was explained by environmental covariates. Early patterns of postfire lodgepole pine regeneration, which were contingent on prefire serotiny and fire severity, remained the dominant driver of stand structure and function. We observed mechanisms that would lead to convergence in stem density

    2011-01-01

    The Co-operative Programme for the Exchange of Scientific and Technical Information Concerning Nuclear Installation Decommissioning (CPD) is a joint undertaking according to Article 5 of the Statute of the NEA. Concluded in 1985, the Agreement constituting the CPD has been continuously extended, although modified in 2003, with the current programme period lasting until the end of 2013. This report provides information about the participants, structure and achievements of the Co-operative Programme and the projects involved. The projects in the Programme have a broad range of characteristics and cover various types of reactors and fuel facilities. The number of projects in the programme has grown from 42 to 59 over the past five years. The Programme now covers 35 reactor related projects and 24 fuel related projects representing a wide selection of facility types in each category. Also, all phases of decommissioning - from active dismantling to safe store and to completed decommissioning back to 'green field conditions' - are represented. Over the 25 years of experience of the Co-operative Programme on Decommissioning, and in particular through the information exchange and review within the TAG, it has become evident that: - decommissioning can and has been done in a safe, cost-effective and environmentally friendly manner; - the evolution of technologies have demonstrated their effectiveness in performance improvements in all aspects of conducting decommissioning projects; - the upkeep and maintenance of design, construction and operational records can significantly enhance performance through all stages of a decommissioning project; - in the absence of waste disposal facilities, interim waste storage facilities with integrated waste processing facilities can effectively be used to keep all levels of waste streams moving and avoid delays to project schedules; - cleanup of material for recycle and reuse or disposal as conventional waste is cost

    1983-01-01

    Twenty years ago a radioisotope department was established in the old building of the 3rd Medical Clinic in Prague 2. The department is suitably placed and meets present requirements. It was set up as part of the 3rd Medical Clinic and of the Laboratory for endocrinology and Metabolism which gave it its main orientation and scope. Its present scope is much broader. In the twenty years since it was established 115,800 examinations were carried out, some 40 examination methods were introduced, 103 publications published, members of the department were co-authors of another 113 publications, they completed 11 research projects. The production of the department represents a substantial part of laboratory material especially in the diagnosis of endocrinopathy and metabolic disorders at the Clinic and is a significant part of the material of a number of research projects.

    1993-02-10

    In June of 1992, the U. S. Department of Energy (DOE) awarded assistance Medical University of South Carolina (MUSC) for the Environmental Hazards Assessment Program, The first year of the program is primarily a planning year. We have aggressively pursued input into the EHAP program to begin to understand where our efforts fit within other efforts underway nationally. We have also begun some direct activities at MUSC to begin the program. Part of this report is devoted to informing DOE of what we have accomplished so far this year. In our efforts to plan, we have identified several changes in emphasis for the program. These changes affect the original plan in terms of projected milestones and budget allocations. Part of this report describes these changes and describes the proposed changes to the budget. We are not requesting additional funds for this year. Simply, we are requesting some change in allocations to budget categories. Therefore, our report to DOE is a combination status report, program plan, and request for reallocation of budget.

    The Tank Waste Remediation System (TWRS) Multi-Year Work Plan (MYWP) documents the detailed total Program baseline and was constructed to guide Program execution. The TWRS MYWP is one of two elements that comprise the TWRS Program Management Plan. The TWRS MYWP fulfills the Hanford Site Management System requirement for a Multi-Year Program Plan and a Fiscal-Year Work Plan. The MYWP addresses program vision, mission, objectives, strategy, functions and requirements, risks, decisions, assumptions, constraints, structure, logic, schedule, resource requirements, and waste generation and disposition. Sections 1 through 6, Section 8, and the appendixes provide program-wide information. Section 7 includes a subsection for each of the nine program elements that comprise the TWRS Program. The foundation of any program baseline is base planning data (e.g., defendable product definition, logic, schedules, cost estimates, and bases of estimates). The TWRS Program continues to improve base data. As data improve, so will program element planning, integration between program elements, integration outside of the TWRS Program, and the overall quality of the TWRS MYWP. The MYWP establishes the TWRS baseline objectives to store, treat, and immobilize highly radioactive Hanford waste in an environmentally sound, safe, and cost-effective manner. The TWRS Program will complete the baseline mission in 2040 and will incur costs totalling approximately 40 billion dollars. The summary strategy is to meet the above objectives by using a robust systems engineering effort, placing the highest possible priority on safety and environmental protection; encouraging open-quotes out sourcingclose quotes of the work to the extent practical; and managing significant but limited resources to move toward final disposition of tank wastes, while openly communicating with all interested stakeholders

    The Marine Biodiversity Observation Network (MBON) is a partnership between academic, private, and government researchers seeking to understand how marine biodiversity changes over long periods of time. In this context, a study of the multi-agency Reef Visual Census (RVC) data, collected over twenty years in the Florida Keys National Marine Sanctuary (FKNMS), was analyzed to measure possible changes in reef fish abundances as a result of possible predation by lionfish predation or due to related trophic cascading. Lionfish were first sighted in the FKNMS in January 2009, with abundances and frequency of occurrence increasing three to six fold throughout the sanctuary by 2011. Their high consumption rates of smaller fish, coupled with their rapidly increasing densities may be having a significant effect on coral reef fish communities. The study compares the natural variability in reef fish abundances from 1994-2009 in the FKNMS, 15 years prior to the first lionfish detected in the sanctuary, to changes in reef fish abundances 5 years after the invasion. The MBON project also aims to develop environmental DNA (eDNA) technology for conducting biodiversity assessments. eDNA is an emerging technique that seeks to quantify biodiversity in an area by obtaining genetic material directly from environmental samples (soil, sediment, water, etc.) without any obvious signs of biological source material. All marine organisms shed DNA into their surrounding habitat, leaving a "fingerprint." Similar to forensic science, the DNA can be collected from seawater and analyzed to determine what species were recently present. The MBON team is evaluating whether eDNA can be used to adequately monitor reef fish biodiversity in coral reef ecosystems. We will compare species detected in our samples to the taxonomic composition of reef fish communities at the sample site as recorded over the past twenty years in the Reef Visual Census data.

    2016-01-01

    Complying with the European and French laws, each year, RTE prepares and publicizes a Ten-Year Network Development Plan (NDP) to meet the expectations of its stakeholders and customers. The NDP lists the network development projects that RTE plans to complete and commission over a 3-year period and presents the main power transmission infrastructure work envisaged for the next Ten-years. Beyond, it outlines the possible network adaptation needs for a variety of energy transition scenarios. Over the next 10 years, the network investments will make it possible to: - Meet the goals of the Regional Climate Air Energy Plans, - Create 4 GW of extra offshore wind generation integration capacity and 10 GW of additional interconnection capacity, 2/3 more than the current capacity, - Enable the development of economically and demographically dynamic areas, with safe and high-standard electricity supply. In the coming decade, RTE plans: - 1,200 km of new underground and sub-sea DC links, along with their associated converter stations; - 600 km of existing equipment upgrades or new overhead 400 kV AC circuits substituting existing power lines. - and, at the same time, nearly 900 km of underground lines and just over 400 km of overhead 225 kV AC lines should be built. 400 projects are listed in this NDP: - 21% of the operations are on overhead lines (for 3/4 new lines or upgrade and for 1/4 dismantling of existing assets) - 27% concern new underground lines; - 52% on substation adaptations (about 20 new RTE substations and 100 new customer substations connected). Globally, nearly 80% of the network is developed underground or sub-sea. This edition of the Network Development plan is further enriched. In particular, it explains more thoroughly the link between the integration of renewable energy and the entailed development of the transmission network. It also provides a focus on smart grids. This edition relies on mid and long term scenarios describing the evolution of the

  13. Safety and health five-year plan, Fiscal years 1995--1999

    International Nuclear Information System (INIS)

    1994-10-01

    This report describes efforts by the Department of Energy (DOE) to size and allocate funding to safety and health activities that protect workers and the public from harm. Although it is well recognized that virtually every aspect of an operation has health and safety implications, this effort is directed at identifying planned efforts specifically directed at health and safety. The initial effort, to compile information for the period covering FY 1994--1998, served two primary needs: (1) to document what was actually taking place in the DOE Complex, from a budget and resource utilization standpoint (how the complex was reacting to the calls for greater protection for workers and the public); and (2) to embark on an effort to utilize forward-looking management plans to allocate resources to meet safety and health needs (to begin to be proactive). It was recognized that it would take several years to achieve full acceptance and implementation of a single, DOE-wide approach toward planning for safety and health, and to develop plans that emphasized the benefits from both risk management and accident prevention strategies. This report, describing safety and health plans and budgets for FY 1995, reflects the increasing acceptance of risk-based strategies in the development of safety and health plans. More operations are using the prioritization methodology recommended for the safety and health planning process, and more operations have begun to review planned expenditures of resources to better assure that resources are allocated to the highest risk reduction activities

    This article addresses the continued need for the behavior change process that must be managed long after materiel requirements planning (MRP II) implementation. Mason & Hanger, Pantex Plant is the final assembly and dismantlement facility for all United States nuclear weapons. On October 1, 1990, Mason & Hanger implemented a full production cutover to MRP II. One year later, following class A certification, the MRP II implementation team is still actively managing the change process through education and training programs and overall continuous improvement initiatives. Actual behavior change problems are identified together with the proven solutions implemented in a government-owned, contractor-operated facility environment. Performance measurements ranging from senior management planning to shop floor accomplishments and cost variance reports are shown as normal management tools used to identify target improvement areas.

    The aims of this study were to introduce our experience with treating patients with pancreatic solid pseudopapillary tumors (SPTs) and to investigate the clinical risk factors for recurrence of SPTs because no consensus has been established to date. One hundred twenty-one patients underwent surgical resection from January 2008 to December 2015 in our institution. Clinical data were collected from the standardized reports. Of the 121 patients, 93 (76.9%) were women, 28 (23.1%) were men, and the mean age at diagnosis was 33.7 years (range, 11-68 years). Sixty patients were subjected to short-term complications, and 8 patients experienced long-term complications, some of whom may require surgery. The tumor located in the distal pancreas (P = 0.02), and a Ki-67 index value > 1.5 (P = 0.01) indicated malignancy according to the World Health Organization 2000 classification. One hundred three patients responded to follow-up, and 3 cases (2.9%) were subject to liver metastases. Recurrence was more frequently observed in tumors classified as high-grade malignancies according to the World Health Organization 2010 classification (P = 0.013), synchronous metastases (P < 0.001), peripancreatic fat infiltration (P = 0.018), and lymphovascular invasion (P < 0.001). Evaluating the risk of the recurrence of SPTs still requires systematic and multicenter trials in the future, even some pathological features showed statistical differences.

    Children with Down syndrome (DS) are an everyday casuistry of pediatric clinical medicine. The prevalence of DS is dependent on socio-demographic and cultural conditions of a community. Antenatal screening is not carried out mainly due to religious views, and the prevalence of DS in our region is really considered a "natural phenomenon". The aim of the study was to analyze some epidemiological characteristics of infants with Down syndrome in the western region of Herzegovina in the period between year 1994-2013. We performed a retrospective analysis of hospital records of children who were supervised and treated at Children's Hospital through the twenty-year period. In this period there were 44,100 liveborn infants. Down syndrome was detected in 78 children (54 male and 24 female). The prevalence is estimated at 1.8/1,000 of live births. Aborted fetuses and stillbirths were not analyzed. 37 (47%) of the parent couples were over 35 years of age. Out of that 65 cytogenetic analysis, a regular type of trisomy 21 was found in 94% of cases, and the translocation in 6%. From major malformations (MM) heart failure was more often present (47%), then the anomaly of the gastrointestinal and genitourinary systems. Ten children (12%) died, most often in the early period of infancy due to complications of the cardiovascular system. The prevalence of DS throughout these two decades has been uniform in the region of western Herzegovina. Improvement in perinatal care in recent years caused higher survival and a better quality of life for the children with DS and thus their families. DS is less a desirable family tragedy, and increasingly a tolerable family fate.

    Introduction: The acquisition, management, communication, and long-term stewardship of natural science data, information, and knowledge are fundamental mission responsibilities of the U.S. Geological Survey (USGS). USGS scientists collect, maintain, and exchange raw scientific data and interpret and analyze it to produce a wide variety of science-based products. Managers throughout the Bureau access, summarize, and analyze administrative or business-related information to budget, plan, evaluate, and report on programs and projects. Information professionals manage the extensive and growing stores of irreplaceable scientific information and knowledge in numerous databases, archives, libraries, and other digital and nondigital holdings. Information is the primary currency of the USGS, and it flows to scientists, managers, partners, and a wide base of customers, including local, State, and Federal agencies, private sector organizations, and individual citizens. Supporting these information flows is an infrastructure of computer systems, telecommunications equipment, software applications, digital and nondigital data stores and archives, technical expertise, and information policies and procedures. This infrastructure has evolved over many years and consists of tools and technologies acquired or built to address the specific requirements of particular projects or programs. Developed independently, the elements of this infrastructure were typically not designed to facilitate the exchange of data and information across programs or disciplines, to allow for sharing of information resources or expertise, or to be combined into a Bureauwide and broader information infrastructure. The challenge to the Bureau is to wisely and effectively use its information resources to create a more Integrated Information Environment that can reduce costs, enhance the discovery and delivery of scientific products, and improve support for science.

    Western, like many other Federal agencies, will face significant and challenging human capital issues in the next decade. The Federal workforce is aging; baby boomers, with their valuable skills and experience, are drawing nearer to retirement and new employees joining the Federal workforce today have different career expectations from the generation that preceded them. The average age of Western’s workforce is approaching 48. Almost a third of the workforce is between 50 and 54 years and most will be eligible to retire in five years. Western has almost twice as many employees who are 55 and older as it has who are 35 and younger. As the workforce ages, the proportion of younger workers is shrinking. The U.S. Census Bureau says you can expect these developments for the next 20 years. The 45 to 65 year-old work group will grow by 54 percent but the 18 to 44 population will rise by only 4 percent. According to the Bureau of Labor Statistics workers age 25 to 44 will decline by 3 million, dropping from 51 percent of the labor force in 1998 to 44 percent in 2008. Western employees who will retire include highly skilled workers in fields such as information technology, engineering, and craft occupations. Deregulation of the electric utility industry and the establishment of regional transmission organizations and independent system operators are also demanding new and different skill mixes than those currently available in Western. Changes in workforce demographic, in the education and skills that will be required in the future, and an increasingly competitive job market, will require flexible and responsive human capital tools to attract and retain talented employees. These trends were the reason for a comprehensive review of Western’s human capital programs to determine its readiness for the future. In July 2001, a team of managers conducted a comprehensive assessment of Western’s human capital needs. The team used the assessment to draft a framework that

  8. The chemical and biological response of two remote mountain lakes in the Southern Central Alps (Italy to twenty years of changing physical and chemical climate

    Directory of Open Access Journals (Sweden)

    Andrea LAMI

    2004-02-01

    Full Text Available Two small high mountain lakes in the Alps were monitored in 1984-2003 to follow their response to changes in human impact, such as deposition of atmospheric pollutants, fish stocking and climate change. The results were compared to occasional samplings performed in the 1940s, and to the remains found in sediment cores. When monitoring started, the most acid-sensitive of them, Lake Paione Superiore, was acidified, with evident effects in its flora and fauna: benthic diatoms assemblage was shifted towards acidophilous species, and zooplankton lost the dominant species, Arctodiaptomus alpinus. Palaeolimnological studies outlined that lake acidification paralleled the increasing input of long-range transported industrial pollutants, traced by spherical carbonaceous particles. On the contrary, the biota of Lake Paione Inferiore appeared to be mainly affected by fish stocking. In the last twenty years, decrease in acid load from the atmosphere led to an improvement in lake water quality, with an increase in both pH and alkalinity. First signs of biological recovery were identified, such as change in diatom flora and appearance of sensitive species among benthic insects. However, climate change and episodic deposition of Saharan dust were important driving factors controlling lake water chemistry. Further monitoring to assess the effects of climate change and of the increasing load of nitrogen and other pollutants is recommended.

    We are a mother and daughter, both health care professionals, who offer a follow-up to an article we published twenty years ago about the impact of each other's ongoing, serious medical problems on our relationship. In this article, we contribute a long-term perspective on the differences between having an illness that is well or poorly understood by medical professionals and the lay community. We also discuss health in the context of identity formation and life stage, as during this interval the daughter left home, graduated college, married, and had two children. Also in this period, the mother survived a third breast cancer and other life-threatening illnesses. We discuss the impact of these experiences on each other and in other important relationships in our lives. Current discourses on daughters of breast cancer survivors do not fit our experience and we speculate about why our story differs. We find that although we continue to contend with serious medical issues that impact our own, each other's, and our families' lives, nonetheless, our lives are rich, rewarding, and "appropriate" for our life stage. That is the news. © 2015 Family Process Institute.

    This retrospective analysis aims to report results of patients with cancer of uterine cervix treated with external-beam radiotherapy (EBR) and high-dose rate (HDR) brachytherapy, using manual treatment planning. From 1975 to 1995, 237 patients with FIGO stages IIB-IVA and mean age of 54.31 years were treated. EBR dose to the whole pelvis was 50 Gy in 25 fractions. Brachytherapy with HDR after-loading cobalt source (Cathetron) was performed following EBR completion with a dose of 30 Gy in three weekly fractions of 10 Gy to point A. Survival, local control, and genitourinary and gastrointestinal complications were assessed. In a median follow-up of 60.2 months, the 10-year overall and disease-free survival rate was 62.4%. Local recurrence was seen in 12.2% of patients. Distant metastases to the lymph nodes, peritoneum, lung, liver, and bone occurred in 25.3% of patients. Less than 6% of patients experienced severe genitourinary and/or gastrointestinal toxicity that were relieved by surgical intervention. No treatment-related mortality was seen. This series suggests that 50 Gy to the whole pelvis together with three fractions of 10 Gy to point A with HDR brachytherapy is an effective fractionation schedule in the treatment of locally advanced cancer of cervix. To decrease the complications, newer devices and treatment planning may be beneficial.

  13. Multi-Year SSL Market Development Support Plan

    2012-05-01

    This plan sets out a strategic, five year framework for guiding DOE's market development support activities for high-performance solid-state lighting (SSL) products for the U.S. general illumination market. The market development support activities described in this plan, which span federal fiscal years 2012 to 2016, are intended to affect the types of SSL general illumination products adopted by the market, to accelerate commercial adoption of those products, and to support appropriate application of those products to maximize energy savings. DOE has established aggressive FY16 goals for these activities, including goals for the types of products brought to market, the market adoption of those products, and the energy savings achieved through use of SSL products. These goals are for the combined effect of DOE's SSL market development support and R and D investment, as well as the leveraged activities of its partners. Goals include: (1) inducing the market introduction of SSL products achieving 140 lumens per Watt (lm/W) for warm white products, and 155 lm/W for cool white products, and (2) inducing sales of high-performance SSL products that achieve annual site electricity savings of 21 terawatt hours (0.25 quadrillion Btus primary energy) by FY16. To overcome identified market barriers and to achieve the above five year goals, DOE proposes to carry out the following strategy. DOE will implement a multi-year program to accelerate adoption of good quality, high performance SSL products that achieve significant energy savings and maintain or improve lighting quality. Relying on lessons learned from past emerging technology introductions, such as compact fluorescent lamps, and using newly developed market research, DOE will design its efforts to minimize the likelihood that the SSL market will repeat mistakes that greatly delayed market adoption of earlier emerging technology market introductions. To achieve the maximum effect per dollar invested, DOE will

    This document summarizes Lawrence Livermore National Laboratory's (LLNL) plan for fusion research on the DIII-D Tokamak, located at General Atomics (GA) in San Diego, California, in the time period FY04-FY08. This document is a companion document to the DIII-D Five-Year Program Plan; which hereafter will be referred to as the ''D3DPP''. The LLNL Collaboration on DIII-D is a task-driven program in which we bring to bear the full range of expertise needed to complete specific goals of plasma science research on the DIII-D facility. This document specifies our plasma performance and physics understanding goals and gives detailed plans to achieve those goals in terms of experimental leadership, code development and analysis, and diagnostic development. Our program is designed to be consistent with the long-term mission of the DIII-D program as documented in the D3DPP. The overall DIII-D Program mission is ''to establish the scientific basis for the optimization of the tokamak approach to fusion energy production''. LLNL Magnetic Fusion Energy (MFE) supports this mission, and we contribute to two areas of the DIII-D program: divertor physics and advanced tokamak (AT) physics. We lead or contribute to the whole cycle of research: experimental planning, diagnostic development, execution of experiments, and detailed analysis. We plan to continue this style in the next five years. DIII-D has identified three major research themes: AT physics, confinement physics, and mass transport. The LLNL program is part of the AT theme: measurement of the plasma current profile, and the mass transport theme: measurement and modeling of plasma flow. In the AT area, we have focused on the measurement and modeling of the current profile in Advanced Tokamak plasmas. The current profile, and it's effect on MHD stability of the high-β ''AT'' plasma are at the heart of the DIII-D program. LLNL has played a key role in the development of the Motional Stark Effect (MSE) diagnostic. Starting

    2016-09-15

    Effects of sewage sludge disposal on sediments and infauna are presented in a unique long-term (22years) data set from the Eastern Mediterranean. While organic carbon (Corg) and metals affected sediment quality in an area which size varied seasonally, the infauna exhibited seasonal "boom and bust" cycle. Metal concentrations declined following load reduction. However, Corg did not decrease and infaunal abundance, closely related to Corg, varied with changes in environmental forcing. Mild winters affected the infaunal populations at the heavily impacted stations, due to anoxic conditions. Planned cessation of disposal is estimated to reduce Corg and metal concentrations to pre-discharge levels. Yet the resettling biota is expected to differ significantly from the pre-discharge one and consist in large part of Erythraean non indigenous species. Copyright © 2016 Elsevier Ltd.

    Over the last 20 years, HIV emerged as the #1 cause of death in African adults, and the Rwanda genocide became the most concentrated mass murder in recorded history. Though one catastrophe surfaced slowly and inexorably while the other smoldered for years before exploding in 1994, the lessons learned are similar. In both situations, the international community has combined moral bankruptcy with a spectacular display of incompetence. Genocide masterminds continue living in Michigan, Minneapolis and Boston, brazenly planning the final extermination of the Tutsi. Students of law, diplomacy and international development are astoundingly sanguine about this, as though our current abdication of responsibility today is mitigated by the centuries of unprincipled idiots who preceded us. If medicine operated this way we'd still be treating syphilis with arsenic. Unfortunately, medicine has lost the moral high ground in Africa through missed opportunities and misappropriation of resources. In the last five years we have spent 20% of the US bilateral foreign assistance budget putting 2.5 million Africans on anti-retroviral treatment (ART), while twice that number of new HIV infections occurred. We tested 50 million Africans for HIV without acting on the evidence and common sense: rather than-transmission happens between two people. Had we tested Africans as couples, a prevention strategy proven to be effective in multiple publications since the early '90s, we could have averted more HIV infections than we are now treating, and at a fraction of the cost.

    Astronomy is enjoying a golden age of fundamental, exciting discoveries. Europe is at the forefront, thanks to 50 years of progress in cooperation. To remain ahead over the next two to three decades, Europe must prioritise and coordinate the investment of its financial and human resources even more closely. The ASTRONET network, backed by the entire European scientific community, supported by the European Commission, and coordinated by the CNRS, today presents its Roadmap for a brilliant future for European astronomy. ESO's European Extremely Large Telescope is ranked as one of two top-priority large ground-based projects. Astronet and the E-ELT ESO PR Photo 43a/08 The E-ELT Europe is a leader in astronomy today, with the world's most successful optical observatory, ESO's Very Large Telescope, and cutting-edge facilities in radio astronomy and in space. In an unprecedented effort demonstrating the potential of European scientific cooperation, all of European astronomy is now joining forces to define the scientific challenges for the future and construct a common plan to address them in a cost-effective manner. In 2007, a top-level Science Vision was prepared to assess the most burning scientific questions over the next quarter century, ranging from dark energy to life on other planets. European astronomy now presents its Infrastructure Roadmap, a comprehensive 20-year plan to coordinate national and community investments to meet these challenges in a cost-effective manner. The Roadmap not only prioritises the necessary new frontline research facilities from radio telescopes to planetary probes, in space and on the ground, but also considers such key issues as existing facilities, human resources, ICT infrastructure, education and outreach, and cost -- of operations as well as construction. This bold new initiative -- ASTRONET -- was created by the major European funding agencies with support from the European Commission and is coordinated by the National Institute

    Twenty years after the Chernobyl accident, above 1.5 million people in 14 subjects of the Russian Federation continue to live in the area of radioactive contamination. More than 180,000 of the Russians were affected by radiation, when participating in elimination of the accident and its consequences. Since the first days of the accident, the public health service faced a task to develop and implement the measures on minimization of medical effects of the accident and public provision with medical assistance, including the employees of the nuclear power plant and the participants in mitigation of the accident. The health of the liquidators and the public living in the contaminated areas is the most socially significant issue being solved in the process of elimination of the Chernobyl consequences. Radiological effects have been the focus of attention for the overall 20-year period. The radiation protection system was based on performance of the two conditions, namely: absolute prevention of acute (deterministic) effects and reduction in the risk of remote (stochastic) effects to acceptable (justified) levels. As early as in 1986, a decision was made to create the unified system of medical observation for the individuals affected by radiation as a result of the Chernobyl accident. The Russian State Medical and Dosimetry Register (RSMDR) was established on the basis of the Medical Radiological Research Center of the Russian Academy of Medical Sciences. The two most suffered public groups were defined as a result of research activity of the Register. These are the children (at the moment of the accident) living in the highly contaminated areas and the liquidators who have obtained the exposure dose above 150 mGy. According to the Register's data, 122 cases (54%) out of 226 thyroid cancers revealed during the years 1991-2003 among the children (at the moment of the Chernobyl catastrophe) from the Bryansk region can be considered as radiation-stipulated.

Retrospective analysis of the records of PMRC, Research Centre, Jinnah Postgraduate Medical Centre, Karachi, from 1987 to 2007 were reviewed. A special flow sheet was made where information of all patients with viral liver disease was entered. Patients having complete information of viral markers were included in the analysis. Cases with HBsAg, Anti HBc IgM positive and raised ALT were considered as acute Hepatitis B. HBs Ag/ Anti HBc IgG positive were considered as chronic Hepatitis B. Delta antibody positive with or without HBsAg were considered as Delta Hepatitis. Anti HCV positive and raised ALT more than ten times for less than 6 months were considered as acute Hepatitis C, whereas Anti HCV and HCV-RNA positive with or without raised ALT for more than six months were considered as chronic Hepatitis C. Anti HEV IgM and Anti HAV IgM positive were considered as acute Hepatitis E and A respectively. A total of 5193 cases fulfilling all criteria of viral hepatitis were seen in the past 21 years. Of the total 3247 (62.5 %) were males and 1946 (37.5 %) females giving a male to female ratio of 1.7:1 Hepatitis C was the most common infection seen in 2896 cases (55.8 %), followed by Hepatitis B in 1691 cases (32.6 %). Seventy five percent cases of Hepatitis B were males and 25 % females while 55% Hepatitis C cases were males and 45 % females. Hepatitis B was seen a decade earlier in different age groups than hepatitis C. Overall, out of the total 5193 cases, 2294 (44.2%) were of chronic hepatitis, 1430 (27.5%) cirrhosis, 1083 (20.8%) carriers and 346 (6.7%) had acute hepatitis (hepatitis B; 214 (61.8%), hepatitis C; 21 (6.0%). While hepatitis B and hepatitis C both were present in 3 (1.3%). Hepatitis E was 70 (20.2%) hepatitis A 12 (3.5%) and all markers were negative in 26 (7.5%) cases).

    As reflected in the U.S. ''National Energy Policy'', nuclear energy has a strong role to play in satisfying our nation's future energy security and environmental quality needs. The desirable environmental, economic, and sustainability attributes of nuclear energy give it a cornerstone position, not only in the U.S. energy portfolio, but also in the world's future energy portfolio. Accordingly, on September 20, 2002, U.S. Energy Secretary Spencer Abraham announced that, ''The United States and nine other countries have agreed to develop six Generation IV nuclear energy concepts''. The Secretary also noted that the systems are expected to ''represent significant advances in economics, safety, reliability, proliferation resistance, and waste minimization''. The six systems and their broad, worldwide research and development (R and D) needs are described in ''A Technology Roadmap for Generation IV Nuclear Energy Systems'' (hereafter referred to as the Generation IV Roadmap). The first 10 years of required U.S. R and D contributions to achieve the goals described in the Generation IV Roadmap are outlined in this Program Plan

    The River Protection Project (RPP), formerly the Tank Waste Remediation System (TWRS), is a major part of the U.S. Department of Energy's (DOE) Office of River Protection (ORP). The ORP was established as directed by Congress in Section 3139 of the Strom Thurmond National Defense Authorization Act for Fiscal Year (FY) 1999. The ORP was established to elevate the reporting and accountability for the RPP to the DOE-Headquarters level. This was done to gain Congressional visibility and obtain support for a major $10 billion high-level liquid waste vitrification effort

    Autism spectrum disorder (ASD) is characterized by persistent deficits in social communication and interaction, and restrictive and repetitive patterns of behavior, interests or activities. This study aimed to analyze trends in ASD diagnosis and intervention in 20 years of data from the Beijing Stars and Rain Education Institute for Autism (SR), the first autism intervention center in mainland China, and from a recent survey of members of the Heart Alliance, an industry association of autism intervention centers in China. We analyzed the registration data at the SR from 1993 to 2012 for a total of 2,222 children who had a parent-reported diagnosis of ASD and 612 of 'autistic tendencies'. Most of the children who were the primary focus of our analyses were age six and under. We also analyzed results of a survey we conducted in 2013 of 100 member centers of the Heart Alliance. Generalized Estimating Equations, multiple linear regression and the Mann-Whitney test were used for data analysis. Statistically significant findings are reported here. The number of hospitals where SR children received their diagnosis increased from several in the early 1990s to 276 at present. The proportion of 'autistic tendencies' diagnosis increased 2.04-fold from 1998 to 2012 and was higher for children diagnosed at a younger age. The mean age at first diagnosis of ASD or 'autistic tendencies' decreased by 0.27 years every decade. A higher level of parental education was statistically significantly associated with an earlier diagnosis of the child. The mean parental age at childbirth increased by about 1.48 years per decade, and the mean maternal age was 1.40 and 2.10 years higher than that in the national population censuses of 2000 and 2010, respectively. At the time of the survey 3,957 children with ASD were being trained at the 100 autism intervention centers. Ninety-seven of these centers opened after the year 2000. Economically underdeveloped regions are still underserved. This

    This huge report proposes a rather detailed overview of the evolution of the French policy to reduce greenhouse gas emissions in order to struggle against climate change and global warming. The introduction proposes a large synthesis by addressing the challenges of this struggle, the French attenuation trajectory within the European framework, the relationship between energy and climate policies, the progressive development of a method, the increasing number of involved actors, the commitment of the various economic sectors and local communities. Some recommendations are made within the perspective of the next Conference on Climate (COP21) and beyond. Then, the report first part addresses the 1992-2014 period, describes the international context (evolutions of greenhouse gas emissions in the world and per sector), presents the different international agreements (Kyoto protocol, Doha amendment, European commitments, the role of France in the world and European dynamics), gives an overview of the progressive emergence of a climate policy in France and of its results (global decrease of emissions, but with variations among sectors), proposes a comparison of climate policies debated and implemented in different countries (China, USA, Swede, United Kingdom, Italy, Germany). An analysis discusses the obtained results, the difficult implementation of Climate plans in France, the coherence of public policies, the territorialisation of the climate challenge, and the influence of the economic context on the evolution of emissions. The next part outlines and comments how the French population becomes always more aware of the climate challenge, how intermediate bodies tend to take charge of this issue, how economic activities progressively integrate the reduction of greenhouse gas emissions, and how local policies can also tackle the problem. Perspectives are then discussed: on the long term (factor 4 objective for the various sectors), on the medium term (by 2020-2030), and

    To assess the 5-year progression of erosions and joint space narrowing (JSN) and their associations with rheumatoid factor (RF) status in 2 large, multicenter, early rheumatoid arthritis cohorts, spanning 25 years. Radiographic joint damage was recorded using the Sharp/van der Heijde (SHS) method in the Early Rheumatoid Arthritis Study (ERAS), 1986-2001, and the Early Rheumatoid Arthritis Network (ERAN), 2002-2013. Mixed-effects negative binomial regression estimated changes in radiographic damage over 5 years, including erosions and JSN, separately. RF, along with age, sex, and baseline markers of disease activity were controlled for. A total of 1,216 patients from ERAS and 446 from ERAN had radiographic data. Compared to ERAS, ERAN patients had a lower mean total SHS score at baseline (ERAN 6.2 versus ERAS 10.5; P < 0.001) and mean annual rate of change (ERAN 2.5 per year versus ERAS 6.9 per year; P < 0.001). Seventy-four percent of ERAS and 27% of ERAN patients progressed ≥5 units. Lower scores at baseline in ERAN were largely driven by reductions in JSN (ERAS 3.9 versus ERAN 1.2; P < 0.001), along with erosions (ERAS 1.9 versus ERAN 0.8; P < 0.001). RF was associated with greater progression in each cohort, but the absolute difference in mean annual rate of change for RF-positive patients was substantially higher for ERAS (RF positive 8.6 versus RF negative 5.1; P < 0.001), relative to ERAN (RF positive 2.0 versus RF negative 1.9; P = 0.855). Radiographic progression was shown to be significantly reduced between the 2 cohorts, and was associated with lower baseline damage and other factors, including changes in early disease-modifying antirheumatic drug use. The impact of RF status as a prognostic marker of clinically meaningful change in radiographic progression has markedly diminished in the context of more modern treatment. © 2017, American College of Rheumatology.

    Time-series sediment traps were deployed for nearly 20 years (1990-2009) at two long-term locations: Station SA (49°N, 174°W, trap depth 4,800 m, water depth 5,400 m) in the central subarctic Pacific, and Station AB (53.5°N, 177°W, trap depth 3,200 m, water depth 3,800 m) in the southern Bering Sea. Among many biogenic particles, calcareous nannoplankton represented nearly half or more of the entire calcium carbonate fluxes of the regions. Dominant taxa include Coccolithus pelagicus and Emiliania huxleyi. The flux maxima of the former taxon occurred twice a year during June and October-November, whereas that of the latter taxon only occurred primarily once a year in November at both stations, indicating environmental preferences of the taxa. Among many environmental conditions, the fluxes of Emiliania huxleyi showed strong correlations with both water temperatures above 45 m depth and air temperatures (these parameters taken with one-month lag [earlier values] considering sinking time of ca. a month to the respective trap depths). Coccolithus pelagicus, on the other hand, showed lower values in the correlation with temperatures (Tsutsui et al., 2016), indicating that this taxon is somewhat more dependent on other factors such as nutrients compared to those of E. huxleyi. The timings of the seasonal flux maxima of calcareous nannoplankton are quite different from and later than those of other taxonomic groups such as diatoms and silicoflagellates. The primary seasonal flux maxima of diatoms and silicoflagellates, for example, occurred in May, a month earlier than the June maximum of C. pelagicus, and secondary seasonal flux maxima occurred in August, 2-3 months earlier than those of calcareous nannoplankton at both stations, based on 8 year flux records for diatoms (Onodera and Takahashi, 2009) and 4 year records for silicoflagellates (Onodera and Takahashi, 2012).

Several promising varieties were selected and released for farmers to produce in the large areas that occupied 50-90% percentage of soybean cultivated areas in Vietnam. These varieties have high-yield 1.5-3.5 tons/ha, short growth duration 75-100 days, tolerance to cold and hot temperature and can be planted in 3 crops per year (Winter, Spring and Summer season) over 35-40 thousands ha/year. At present, the mutagens are being used for defect- orientated repair of some promising hybrid lines, in order to contribute new good varieties to soybean production in Vietnam. (author)

    Hepatitis B virus (HBV) and human immunodeficiency virus (HIV) share common risk factors. The parallel description of their frequency over time may help capture their similarities and differences. Using data from the National Transfusion Center of Abidjan, we estimated the following over a 20-year period: (1) the prevalence of HIV and hepatitis B surface antigen (HBsAg) positivity at first contact; and (2) the incidence of HIV and HBsAg seroconversion in negative first-time blood donors. Between 1992 and 2012, 422319 donors (men [M] = 74%) provided 1063825 blood donations. For first-time donors, HIV prevalence decreased from 7.1% (M = 5.9%, women [W] =11.0%) in 1992-1994 to 1.1% (M = 0.8%, W = 2.0%) in 2010-2012. Prevalence of HBsAg positivity remained stable at 10.8% (M = 11.7%, W = 7.3%) in 1992-1994 to 11.1% (M = 12.5%, W = 7.1%) in 2010-2012. Among regular donors (N = 129256), the incidence of becoming HIV or HBsAg positive, respectively, decreased from 4.9 per 100 (M = 4.5, W = 8.6) and 7.3 per 100 person-years (M = 7.8, W = 2.3) in 1992-1994 to 0.07 (M = 0.06, W = 0.11) and 0.2 per 100 person-years (M = 0.2, W = 0.2) in 2010-2012. Human immunodeficiency virus prevalence and incidence decreased dramatically over time, whereas HBV prevalence remained stable. Incidence of HBsAg seroconversion, although decreasing, still reached unexpected levels, suggesting that the risk of HBV infection in adults may be higher than expected. Hepatitis B surface antigen-negative blood-donors should be offered HBV vaccination.

    This report examines the association between mortality from all causes during a 21-year period and frequency of consumption of 28 specific foods among 27,530 adult California members of the Seventh-Day Adventist Church. Food consumption was measured at the beginning of the study (1960) by a self-administered questionnaire. Deaths were identified by computer-assisted matching of study subjects to the file of death certificates for all deaths that occurred in California during 1960-1980. All-cause mortality showed a significant negative association with green salad consumption and a significant positive association with consumption of eggs and meat. For green salad and eggs, the association was stronger for women; for meat, the association was stronger for men. All the observed associations were adjusted for age, sex, smoking history, history of major chronic disease, and age at initial exposure to the Adventist Church.

    After severe reactor emergencies with release of radioactive iodine, elevated thyroid cancer risk in children and adolescents is considered the main health consequence for the population exposed. We studied thyroid cancer outcome after 11.3 years' median follow-up in a selected, very high-risk cohort, 234 Chernobyl-exposed Belarusian children and adolescents undergoing postsurgical radioiodine therapy (RIT) in Germany. Cumulatively 100 children with or (without; n = 134) distant metastasis received a median 4 (2) RITs and 16.9 (6.6) GBq, corresponding to 368 (141) MBq/kg iodine-131. Outcomes were response to therapy and disease status, mortality, and treatment toxicity. Of 229 patients evaluable for outcome, 147 (64.2%) attained complete remission [negative iodine-131 whole-body scan and TSH-stimulated serum thyroglobulin (Tg) 10 μg/L, decrease from baseline in radioiodine uptake intensity in ≥ 1 focus, in tumor volume or in Tg). Except for 2 recurrences (0.9%) after partial remission, no recurrences, progression, or disease-specific mortality were noted. One patient died of lung fibrosis 17.5 years after therapy, 2 of apparently thyroid cancer-unrelated causes. The only RIT side effect observed was pulmonary fibrosis in 5 of 69 patients (7.2%) with disseminated lung metastases undergoing intensive pulmonary surveillance. Experience of a large, very high-risk pediatric cohort with radiation-induced differentiated thyroid carcinoma suggests that even when such disease is advanced and initially suboptimally treated, response to subsequent RIT and final outcomes are mostly favorable.

    Most manipulation experiments simulating global change in tundra were short-term or did not measure plant growth directly. Here, we assessed the growth of three shrubs (Cassiope tetragona, Empetrum hermaphroditum and Betula nana) at a subarctic heath in Abisko (Northern Sweden) after 22 years of warming (passive greenhouses), fertilisation (nutrients addition) and shading (hessian fabric), and compare this to observations from the first decade of treatment. We assessed the growth rate of current-year leaves and apical stem (primary growth) and cambial growth (secondary growth), and integrated growth rates with morphological measurements and species coverage. Primary- and total growth of Cassiope and Empetrum were unaffected by manipulations, whereas growth was substantially reduced under fertilisation and shading (but not warming) for Betula. Overall, shrub height and length tended to increase under fertilisation and warming, whereas branching increased mostly in shaded Cassiope. Morphological changes were coupled to increased secondary growth under fertilisation. The species coverage showed a remarkable increase in graminoids in fertilised plots. Shrub response to fertilisation was positive in the short-term but changed over time, likely because of an increased competition with graminoids. More erected postures and large, canopies (requiring enhanced secondary growth for stem reinforcement) likely compensated for the increased light competition in Empetrum and Cassiope but did not avoid growth reduction in the shade intolerant Betula. The impact of warming and shading on shrub growth was more conservative. The lack of growth enhancement under warming suggests the absence of long-term acclimation for processes limiting biomass production. The lack of negative effects of shading on Cassiope was linked to morphological changes increasing the photosynthetic surface. Overall, tundra shrubs showed developmental plasticity over the longer term. However, such plasticity

    Objective: “History, Theory, Ethics of Medicine” (German: “Geschichte, Theorie, Ethik der Medizin”, abbreviation: GTE) forms part of the obligatory curriculum for medical students in Germany since the winter semester 2003/2004. This paper presents the results of a national survey on the contents, methods and framework of GTE teaching. Methods: Semi-structured questionnaire dispatched in July 2014 to 38 institutions responsible for GTE teaching. Descriptive analysis of quantitative data and content analysis of free-text answers. Results: It was possible to collect data from 29 institutes responsible for GTE teaching (response: 76%). There is at least one professorial chair for GTE in 19 faculties; two professorial chairs or professorships remained vacant at the time of the survey. The number of students taught per academic year ranges from 350. Teaching in GTE comprises an average of 2.18 hours per week per semester (min: 1, max: 6). Teaching in GTE is proportionally distributed according to an arithmetic average as follows: history: 35.4%, theory 14.7% and ethics 49.9%. Written learning objectives were formulated for GTE in 24 faculties. The preferred themes of teaching in history, theory or ethics which according to respondents should be taught comprise a broad spectrum and vary. Teaching in ethics (79 from a max. of 81 possible points) is, when compared to history (61/81) and theory (53/81), attributed the most significance for the training of medical doctors. Conclusion: 10 years after the introduction of GTE the number of students and the personnel resources available at the institutions vary considerably. In light of the differences regarding the content elicited in this study the pros and cons of heterogeneity in GTE should be discussed. PMID:28584871

    Within the first month after being confirmed as this country's sixth secretary of energy, Admiral James D. Watkins (US Navy, Retired) promised Congress that he would deliver a comprehensive plan that outlines specific actions to undertake over the next 5 yr to achieve compliance with US environmental laws and to begin to clean up and restore those sites that we have contaminated over the past 40 yr. The Environmental Restoration and Waste Management Five-Year Plan was published in August 1989. As the admiral committed, the plan established and documented an agenda for compliance and cleanup against which progress in the area of environmental restoration and waste management would be measured and specifically identified actions and commitments to achieve this progress. In November 1989, an additional chapter identifying the applied research, development, demonstration, testing, and evaluation (RDDT and E) activities that would support the implementation of the plan was published. Last June, the US Department of Energy (DOE) issued the first annual update of the 5-yr plan. This update covers the years 1992-1996, notes the progress achieved during the past year, and incorporates the scope of both the original plan and the RDDT and E plan. The plan is divided into five sections: corrective activities, environmental restoration, waste operations, technology development, and transportation. Each section explains DOE's overall policies and plans for achieving compliance and cleanup at DOE's nuclear-related facilities

    1978-11-01

    This estimate covers decommissioning costs of facilities for the receipt, handling, and storage in bedded salt of canistered spent fuel assemblies from both BWR and PWR commercial power plants. The estimate includes all decommissioning costs for a repository, based on 25-year retrievability, constructed in accordance with the design shown in Conceptual Design Report (CDR), as modified by Special Study No. 1 (KE Report No. 78-60-RE) and decommissioned in accordance with the program outlined in the Conceptual Design Description Report, KE Report No. 78-58-R. Costs for Operating Contractor personnel on the site at this time are included in this report and not in the Operating Cost Estimate (KE Report 78-63-RE). The operating cost estimates end with the completion of storage room backfilling. The three major elements of decommissioning are: demolition of surface facilities, backfilling of main entries and airways, and shaft liner removal and shaft plugging. EDIT, ECON, and DELOX computer programs and a chart of accounts were furnished by UCC-ND under direction of the Government and the line item-capital-cost estimate was prepared according to the prescribed format. The decommissioning cost estimate referenced herein is in the same format as its companion line item-capital-cost estimate KE Report 78-62-RE

    For 20 years, the Ministry of Health, Labour and Welfare (MHLW, formerly Ministry of Health and Welfare (MHW)) has been trying to increase transparency of the review process for approving reports in order to promote the rational use of newly approved drugs and medical devices. The first Summary Basis of Approval (SBA) was published by MHW in 1994. In 1999, evaluation reports were prepared by MHW and the Pharmaceuticals and Medical Devices Evaluation Center to make them available to the public. In 2005, a notice from the Chief Executive of the Pharmaceuticals and Medical Devices Agency (PMDA) made procedures for public release of information on reviewing applications for new drugs. In 2006, 90 review reports of newly approved drugs and eight medical devices were revealed on PMDA websites. The dissemination of information by the United States Food and Drug Administration (FDA) and that of the European Medicines Agency (EMA) were studied and compared with that of the MHLW and PMDA. While common technical documents (CTD) for new drugs and summary technical documents (STED) for new medical devices have been released by PMDA, such documents are not released by the FDA and EMA. The European Public Assessment Report (EAPR) summary for the public is an interesting questionnaire approach that uses the "What," "How" and "Why" format. Finally, future proposals for the next decade are also outlined.

    2007-01-01

    The accident in the title occurred in April, 1986 and 20 years after, the international conference of Chernobyl Forum was held in Kiev of Ukraine on details of health problems, of which report is given in World Health Organization (WHO) hp (www.who.int./ionizing r adiation/Chernobyl/ern). The purpose of making the report was the scientific, objective evaluation of health problem to provide residents the correct information and to make recommendation to governments of Russia, Belarus and Ukraine. This paper describes the outline of the WHO report and characteristics of pediatric thyroid cancer increased after the accident. The report has the description about the effect of the accident on human beings including thyroid diseases, tumors, death numbers, mental and genetic influences, and cataract. The increased pediatric thyroid cancer is found mostly the papillocaricinoma, of which pathogenesis is considered to be due to DNA break of the region encoding MAP kinase pathways. Analyses of mitochondrial DNA mutations, by micro-array, of chromosome, and of SNPs have been also performed and have given many suggestive findings. Further continuation of the CTB (Chernobyl Tissue Bank, where nucleic acids of the cancer are stored by international cooperation) activity is concluded to be important for release of residents' anxiety and for understanding of radiation carcinogenesis.

    Over the past 25 years, unionid mussels in the Laurentian Great Lakes of North America have been adversely impacted by invasive dreissenid mussels, which directly (e.g., by attachment to unionid shells) and indirectly (e.g., by competing for food) cause mortality. Despite the invasion, unionids have survived in several areas in the presence of dreissenid mussels. We investigated current spatial patterns in these native mussel refuges based on surveys for unionid mussels across 48 sampling locations (141 sites) in 2011 and 2012, and documented species abundance and diversity in coastal areas of lakes St. Clair and Erie. The highest-quality assemblages of native mussels (densities, richness, and diversity) appear to be concentrated in the St. Clair delta, where abundance continues to decline, as well as in in Thompson Bay of Presque Isle in Lake Erie and in just a few coastal wetlands and drowned river-mouths in the western basin of Lake Erie. The discovery of several new refuge areas suggests that unionids have a broader distribution within the region than previously thought.

    The Chicago Follow-up Study has followed the course of severe mental illness among psychiatric patients for over 20 years after their index hospitalization. Among these patients are 97 schizophrenia patients, 45 patients with schizoaffective disorders, 102 patients with unipolar nonpsychotic depression, and 53 patients with a bipolar disorder. Maximum suicidal activity (suicidal ideation, suicidal attempts and suicide completions) generally declines over the three time periods (early, middle, and late follow-ups) following discharge from the acute psychiatric hospitalization for both males and females across diagnostic categories with two exceptions: female schizophrenia patients and female bipolar patients. A weighted mean suicidal activity score tended to decrease across follow-ups for male patients in the schizophrenia, schizoaffective and depressive diagnostic groups with an uneven trend in this direction for the male bipolars. No such pattern emerges for our female patients except for female depressives. Males’ suicidal activity seems more triggered by psychotic symptoms and potential chronic disability while females’ suicidal activity seems more triggered by affective symptoms. PMID:26881891

    2006-01-01

    Chernobyl Forum in 2003. The mission of the Forum was - through a series of managerial and expert meetings - to generate 'authoritative consensual statements' on the environmental consequences and health effects attributable to radiation exposure arising from the accident, as well as to provide advice on environmental remediation and special health care programmes, and to suggest areas in which further research is required. The Forum was created as a contribution to the United Nations' ten year strategy for Chernobyl, launched in 2002 with the publication of Human Consequences of the Chernobyl Nuclear Accident - A Strategy for Recovery. Over a two year period, two groups of experts from 12 countries, including Belarus, the Russian Federation and Ukraine, and from relevant international organizations, assessed the accident's environmental and health consequences. In early 2005 the Expert Group 'Environment', coordinated by the IAEA, and the Expert Group 'Health', coordinated by the WHO, presented their reports for the consideration of the Chernobyl Forum. Both reports were considered and approved by the Forum at its meeting on 18-20 April 2005. This meeting also decided, inter alia, 'to consider the approved reports... as a common position of the Forum members, i.e., of the eight United Nations organizations and the three most affected countries, regarding the environmental and health consequences of the Chernobyl accident, as well as recommended future actions, i.e., as a consensus within the United Nations system.' This report presents the findings and recommendations of the Chernobyl Forum concerning the environmental effects of the Chernobyl accident. The Forum's report considering the health effects of the Chernobyl accident is being published by the WHO

    The presentation summarizes studies of 1 37Cs and 9 0Sr pollution of the Black Sea Basin carried out by Institute of Biology of the Southern Seas during 1986-2005 following the Chernobyl NPP accident. Its goal was to assess inflows of 1 37Cs and 9 0Sr from the Dnieper and the Danube Rivers, outflow through the Bosphorus Strait, inventories in bottom sediments and temporary evolution of 1 37Cs and 9 0Sr inventories in the Black Sea water column. Besides, the temporary evolution of 1 37Cs and 9 0Sr profiles in the Black Sea deep-water basin was used to estimations of a large-scale vertical water mixing. It has been estimated that the atmospheric fall outs during the first days of May 1986 have deposited 1.7-2.4 PBq of 1 37Cs on the Black Sea surface (nearly 2% of total 1 37Cs release in the environment). Therefore, 1 37Cs inventory in the 0-50 m layer have increased by a factor of 6-10 and the total 1 37Cs inventory in the whole basin have increased at least by a factor of 2 in comparison with the pre-Chernobyl value - 1.4+/-0.3 PBq. 1 37Cs input from the Danube and the Dnieper Rivers was insignificant in comparison with short-term atmospheric fall outs. The results of observations and mathematical modelling are testified that in the surface layers 0-50 and 0-200 m of the Black Sea deep-water basin in 1986-2000 an exponential decreases of the 1 37Cs inventories with an effective half-lifes of 5-6 years and 9-13 years, respectively, have been observed. The process of vertical water mixing has been observed mainly in the 0-200 m layer. The contribution of Chernobyl-origin 9 0Sr from atmospheric fallout was estimated around in 0.1-0.3 PBq. Pre-accident 9 0Sr level nearly 20 Bq m - 3 was reached by 1988. At the same time, an active input of 9 0Sr from the Dnieper and Danube Rivers has been observed. The total amount of 9 0Sr delivered by the two rivers into the Black Sea was estimated to be nearly 0.1 PBq in the 1986-1995. Under conditions of insignificant river input

    Full Text Available Ageing western societies are facing an increasing prevalence of chronic inflammatory and degenerative diseases for which often no effective treatments exist, resulting in increasing health care expenditure. Despite high investments in drug development, the number of promising new drug candidates decreases. We propose that preclinical research in non-human primate can help to bridge the gap between drug discovery and drug prescription.Translational research covers various stages of drug development of which pre-clinical efficacy tests in valid animal models is usually the last stage. Pre-clinical research in non-human primates may be essential in the evaluation of new drugs or therapies when a relevant rodent model is not available. Non-human primate models for life-threatening or severely debilitating diseases in humans are available at the Biomedical Primate Research Centre (BPRC. These have been instrumental in translational research for several decades.In order to stimulate European health research and innovation from bench to bedside, the European Commission (EC has invested heavily in access to non-human primate research for more than 20 years. BPRC has hosted European users in a series of transnational access programs covering a wide range of research areas with the common theme being immune-mediated inflammatory disorders. We present an overview of the results and give an account of the studies performed as part of European Union Framework Programme (EU FP-funded translational non-human primate research performed at the BPRC. The data illustrate value of translational non-human primate research for the development of new therapies and emphasize the importance of EU FP funding

    Full Text Available Objectives. The purpose of this retrospective evaluation of advanced-stage ovarian cancer patients was to compare outcome with published findings from other centers and to discuss future options for the management of advanced ovarian carcinoma patients. Methods. A retrospective series of 340 patients with a mean age of 58 years (range: 17–88 treated for FIGO stage III and IV ovarian cancer between January 1985 and January 2005 was reviewed. All patients had primary cytoreductive surgery, without extensive bowel, peritoneal, or systematic lymph node resection, thereby allowing initiation of chemotherapy without delay. Chemotherapy consisted of cisplatin-based chemotherapy in combination with alkylating agents before 2000, whereas carboplatin and paclitaxel regimes were generally used after 1999-2000. Overall survival and disease-free survival were analyzed by the Kaplan-Meier method and the log-rank test. Results. With a mean followup of 101 months (range: 5 to 203, 280 events (recurrence or death were observed and 245 patients (72% had died. The mortality and morbidity related to surgery were low. The main prognostic factor for overall survival was postoperative residual disease (P<.0002, while the main prognostic factor for disease-free survival was histological tumor type (P<.0007. Multivariate analysis identified three significant risk factors: optimal surgery (RR=2.2 for suboptimal surgery, menopausal status (RR=1.47 for postmenopausal women, and presence of a taxane in the chemotherapy combination (RR=0.72. Conclusion. These results confirm that optimal surgery defined by an appropriate and comprehensive effort at upfront cytoreduction limits morbidity related to the surgical procedure and allows initiation of chemotherapy without any negative impact on survival. The impact of neoadjuvant chemotherapy to improve resectability while lowering the morbidity of the surgical procedure is discussed.

    Mean annual concentration of SO4(-2) in wet-only deposition has decreased between 1988 and 2006 at the paired watershed study at Bear Brook Watershed in Maine, USA (BBWM) due to substantially decreased emissions of SO(2). Emissions of NO(x) have not changed substantially, but deposition has declined slightly at BBWM. Base cations, NH4+, and Cl(-) concentrations were largely unchanged, with small irregular changes of Bear Brook (EB), the reference stream, has been slowly responding to reduced but still elevated acid deposition. Calcium and Mg have declined fairly steadily and faster than SO4(-2), with consequent acidification (lower pH and higher inorganic Al). Eighteen years of experimental treatment with (NH(4))(2)SO(4) enhanced acidification of West Bear Brook's (WB) watershed. Despite the manipulation, NH4+ concentration remained below detection limits at WB, while leaching of NO3- increased. The seasonal pattern for NO3- concentrations in WB, however, remained similar to EB. Mean monthly concentrations of SO4(-2) have increased in WB since 1989, initially only during periods of high flow, but gradually also during base flow. Increases in mean monthly concentrations of Ca(2+), Mg(2+), and K(+) due to the manipulation occurred from 1989 until about 1995, during the depletion of base cations in shallow flow paths in WB. Progressive depletion of Ca and Mg at greater soil depth occurred, causing stream concentrations to decline to pre-manipulation values. Mean monthly Si concentrations did not change in EB or WB, suggesting that the manipulation had no effect on mineral weathering rates. DOC concentrations in both streams did not exhibit inter- or intra-annual trends.

    The Retrovirus Epidemiology Donor Study (REDS), conducted from 1989–2001, and the Retrovirus Epidemiology Donor Study-II (REDS-II), conducted from 2004–2012, were National Heart Lung and Blood Institute (NHLBI) funded multicenter programs focused on improving blood safety and availability in the United States. REDS-II also included international study sites in Brazil and China. The three major research domains of REDS/REDS-II have been infectious disease risk evaluation, blood donation availability, and blood donor characterization. Both programs have made significant contributions to transfusion medicine research methodology by the use of mathematical modeling, large-scale donor surveys, innovative methods of repository sample storage, and establishing an infrastructure that responded to potential emerging blood safety threats such as XMRV. Blood safety studies have included protocols evaluating epidemiologic and/or laboratory aspects of HIV, HTLV I/II, HCV, HBV, WNV, CMV, HHV-8, B19V, malaria, CJD, influenza, and T. cruzi infections. Other analyses have characterized: blood donor demographics, motivations to donate, factors influencing donor return, behavioral risk factors, donors’ perception of the blood donation screening process, and aspects of donor deferral. In REDS-II, two large-scale blood donor protocols examined iron deficiency in donors and the prevalence of leukocyte antibodies. This review describes the major study results from over 150 peer-reviewed articles published by these two REDS programs. In 2011, a new seven year program, the Recipient Epidemiology and Donor Evaluation Study-III (REDS-III), was launched. REDS-III expands beyond donor-based research to include studies of blood transfusion recipients in the hospital setting, and adds a third country, South Africa, to the international program.

    I present a compilation of data describing Mexico's economic performance as it relates to demographic and natural resource characteristics. Statistical correlations suggest that long term economic output and energy efficiency are influenced mostly by human population numbers and fuel consumption rate, although its fluctuations have been clearly driven by those of the world-market oil price throughout 1970-90. Neither energy production, agricultural yield, OPEC's oil price or forest coverage appeared important in determining Mexican GDP response for this 20-year period. Significant relations of these fluctuations were found also in the rates of deforestation, air pollution and agricultural production, being all of these variables seemingly independent of the intrinsic human population growth rate. I discuss how Mexico could bridge the GDP gap with its current Nafta partners from this system-energy perspective. [Spanish] Presento una coleccion de datos que describen el comportamiento de la economia de Mexico relacionado con las caracteristicas demograficas y de sus recursos naturales. Las correlaciones estadisticas sugieren que la produccion economica a largo plazo y la eficiencia de la energia estan influenciadas principalmente por las cifras de poblacion humana y por el regimen de consumo de combustible, si bien sus fluctuaciones han sido claramente impulsadas por los precios del petroleo en mercado mundial a traves de 1970 a 1990. Ni la produccion de energia, el rendimiento agricola, el precio del petroleo de OPEC o la extension de los bosques resultaron importantes en la determinacion de la respuesta del PIB de Mexico para este periodo de 20 anos. Se encontraron relaciones significativas de estas fluctuaciones tambien en los regimenes de deforestacion, contaminacion del aire y produccion agricola, siendo todas esta variables de forma similar independientes de regimen intrinseco del crecimiento de la poblacion humana.

    Full Text Available Hepatitis delta virus (HDV increases morbidity in Hepatitis B virus (HBV-infected patients. In the mid-eighties, an outbreak of HDV fulminant hepatitis (FH in the Central African Republic (CAR killed 88% of patients hospitalized in Bangui. We evaluated infections with HBV and HDV among students and pregnant women, 25 years after the fulminant hepatitis (FH outbreak to determine (i the prevalence of HBV and HDV infection in this population, (ii the clinical risk factors for HBV and/or HDV infections, and (iii to characterize and compare the strains from the FH outbreak in the 1980s to the 2010 HBV-HDV strains. We performed a cross sectional study with historical comparison on FH-stored samples (n = 179 from 159 patients and dried blood-spots from volunteer students and pregnant women groups (n = 2172. We analyzed risk factors potentially associated with HBV and HDV. Previous HBV infection (presence of anti-HBc occurred in 345/1290 students (26.7% and 186/870 pregnant women (21.4%(p = 0.005, including 110 students (8.8% and 71 pregnant women (8.2%, who were also HBsAg-positive (p = 0.824. HDV infection occurred more frequently in pregnant women (n = 13; 18.8% than students (n = 6; 5.4% (p = 0.010. Infection in childhood was probably the main HBV risk factor. The risk factors for HDV infection were age (p = 0.040, transfusion (p = 0.039, and a tendency for tattooing (p = 0.055 and absence of condom use (p = 0.049. HBV-E and HDV-1 were highly prevalent during both the FH outbreak and the 2010 screening project. For historical samples, due to storage conditions and despite several attempts, we could only obtain partial HDV amplification representing 25% of the full-length genome. The HDV-1 mid-eighties FH-strains did not form a specific clade and were affiliated to two different HDV-1 African subgenotypes, one of which also includes the 2010 HDV-1 strains. In the Central African Republic, these findings indicate a high prevalence of previous and

    The well lauded community-based palliative care programme of Kerala, India provides medical and social support, through home-based care, for patients with terminal illness and diseases requiring long-term support. There is, however, limited information on patient characteristics, caregivers and programme performance. This study was carried out to describe: i) the patients enrolled in the programme from 1996 to 2016 and their diagnosis, and ii) the care-giver characteristics and palliative care support from nurses and doctors in a cohort of patients registered during 2013-2015. A descriptive study was conducted in the oldest community-based palliative clinic in Kerala. Data were collected from annual patient registers from 1996 to 2016 and patient case records during the period 2013-2015. While 91% of the patients registered in the clinic in 1996 had cancer, its relative proportion came down to 32% in 2016 with the inclusion of dementia-related illness (19%) cardiovascular accidents (17%) and severe mental illness (5%).Among patients registered during 2013-15, the median number of home visits from nurses and doctors in 12 months were five and one respectively. In the same cohort, twelve months' post-enrolment, 56% of patients died, 30% were in continuing in active care and 7% opted out. Those who opted out of care were likely to be aged care-giver at home, 85% of these care-givers being female. The changing dynamics over a 20-year period of this palliative care programme in Kerala, India, highlights the need for similar programmes to remain flexible and adapt their services in response to a growing global burden of Non Communicable Diseases. While a high death rate is expected in this population, the high proportion of patients choosing to stay in the programme suggests that home-based care is valued within this particular group.

    nonsurgical therapy. The research agenda of RCTs for surgery of CNLBP has not changed substantially in the last 20 years. Technical trials evaluating nuances of surgical techniques significantly predominate. Despite the publication of four RCTs reporting equivocal benefits of surgery for CNLBP between 2001 and 2006, there was no change in the research agenda of subsequent RCTs, and technical trials continued to outnumber indication trials. Rather than clarifying what, if any, indications for surgery exist, investigators in the field continue to analyze variations in surgical technique, which will probably have relatively little impact on patient outcomes. As a result, clinicians unfortunately have little evidence to advise patients regarding surgical intervention for CNLBP. Copyright © 2013 Elsevier Inc. All rights reserved.

    countries were also affected as a result of the atmospheric transfer of radioactive material. These countries also encountered problems in the radiation protection of their populations, but to a lesser extent than the three most affected countries. Although the accident occurred nearly two decades ago, controversy still surrounds the real impact of the disaster. Therefore the IAEA, in cooperation with the Food and Agriculture Organization of the United Nations (FAO), the United Nations Development Programme (UNDP), the United Nations Environment Programme (UNEP), the United Nations Office for the Coordination of Humanitarian Affairs (OCHA), the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), the World Health Organization (WHO) and the World Bank, as well as the competent authorities of Belarus, the Russian Federation and Ukraine, established the Chernobyl Forum in 2003. The mission of the Forum was - through a series of managerial and expert meetings - to generate 'authoritative consensual statements' on the environmental consequences and health effects attributable to radiation exposure arising from the accident, as well as to provide advice on environmental remediation and special health care programmes, and to suggest areas in which further research is required. The Forum was created as a contribution to the United Nations' ten year strategy for Chernobyl, launched in 2002 with the publication of Human Consequences of the Chernobyl Nuclear Accident - A Strategy for Recovery. Over a two year period, two groups of experts from 12 countries, including Belarus, the Russian Federation and Ukraine, and from relevant international organizations, assessed the accident's environmental and health consequences. In early 2005 the Expert Group 'Environment', coordinated by the IAEA, and the Expert Group 'Health', coordinated by the WHO, presented their reports for the consideration of the Chernobyl Forum. Both reports were considered and approved by

    Environmental monitoring of pollutants in international or local programmes has enabled authorities to evaluate the success of political measures over time. Strict environmental legislation and the introduction of cleaner technologies have already led to significant improvements of the air and water quality in many countries. Still, the discharge and deposition of anthropogenic long-range transported pollutants often remain above the critical thresholds and long-term targets defined for terrestrial and aquatic ecosystems even in EU countries. In order to determine the spatial and temporal variation of pollutant and nutrient loads in different environmental media a unique ecological response cadastre (Okologisches Wirkungskataster, OKWI) was set up in the Land of Baden-Württemberg (SW Germany) in the mid 1980s. As a part of the program a state-wide bioindicator network was established in 64 forest and 18 permanent grassland ecosystems, in which selected chemical elements were measured over time. Here, we report on the results of these analyses and discuss the general spatio-temporal trends in pollution loads. Sixty-four forest and 18 permanent grassland plots were established in state-owned forest and nature conservation areas of SW Germany representing different landscapes and geologies of the State of Baden-Württemberg. Apart from performing vegetation relevées in marked plots of either the grassland or forest sites, plant samples were collected in intervals of 2 to 3 years following a standardised protocol. To be able to compare the different monitoring sites, four common species were chosen as indicator species in the grasslands. Later on, also bulk grassland samples were taken regardless of the species. In the forests, foliage of the dominant tree species (Fagus sylvatica, Abiea alba or Fraxinus excelsior) was sampled in the crown of marked trees and from the same species in the herb layer. The elements analysed in the plant material were the essential plant

    This plan covers robotics Research, Development, Demonstration, Testing, activities in the Program for the next five years. These activities range from bench-scale R ampersand D to fullscale hot demonstrations at DOE sites. This plan outlines applications of existing technology to near-term needs, the development and application of enhanced technology for longer-term needs, and an initiation of advanced technology development to meet those needs beyond the five-year plan. The objective of the Robotic Technology Development (RTDP) is to develop and apply robotics technologies that will enable Environmental Restoration and Waste Management operations at DOE sites to be safer, faster and cheaper. Five priority DOE sites were visited in March 1990 to identify needs for robotics technology in ER ampersand WM operations. This 5-Year Program Plan for the RTDP detailed annual plans for robotics technology development based on identified needs. This 5-Year Program Plan discusses the overall approach to be adopted by the RTDP to aggressively develop robotics technology and contains discussions of the Program Management Plan, Site Visit and Needs Summary, Approach to Needs-Directed Technical Development, Application-Specific Technical Development, and Cross-Cutting and Advanced Technology. Integrating application-specific ER ampersand WM needs, the current state of robotics technology, and the potential benefits (in terms of faster, safer, and cheaper) of new technology, the Plan develops application-specific road maps for robotics RDDT ampersand E for the period FY 1991 through FY 1995. In addition, the Plan identifies areas where longer-term research in robotics will have a high payoff in the 5- to 20-year time frame. 12 figs

    The discovery of neutrino mass marks a turning point in elementary particle physics, with important implications for nuclear and astroparticle physics. Here I give a brief update, where I summarize the current status of three-neutrino oscillation parameters from current solar, atmospheric, reactor and accelerator neutrino data, discuss the case for sterile neutrinos and LSND, and also the importance of tritium and double beta decay experiments probing the absolute scale of neutrino mass. In this opinionated look at the present of neutrino physics, I keep an eye in the future, and a perspective of the past, taking the opportunity to highlight Joe Schechter's pioneering contribution, which I have had the fortune to share, as his PhD student back in the early eighties

    Full Text Available The concept of ecotourism evolves differently in developing and developed nations due to which the basic principles of ecotourism are in question. The existing literature on ecotourism suggests ambiguity in conceptual understanding of ecotourism. Due to this qualm, ecotourism is evolving into various forms. Different stakeholders with varying objectives related to ecotourism make it further difficult to form the consensus on what constitutes ecotourism. Without the clear understanding of ecotourism, it is difficult to evolve ethics on which the ecotourism principles are based. The focus of this research is to find out the principle components or themes of ecotourism using a content analysis for the development of ecotourism policy and applications. This study identified six key components of ecotourism which are widely accepted by researchers and could be used to shape the fundamental understanding of ecotourism. These themes are: (1 Nature oriented travel; (2 Support of conservation; (3 Learning and appreciation; (4 Socio-economic development of local area; (5 Support and respect for local culture and (6 Local people (area participation.

    The laboratories of the International Atomic Energy Agency were started in 1959 with a physics laboratory, a chemistry laboratory and an electronics workshop. Early work centred on absolute radionuclide calibrations and on assessments of the consequences of radioactive fallout from atomic weapons testing on the health of the people in Member States. Subsequently, work was started on the use of radioactive and stable isotopes in agriculture, in hydrology, in medical applications, in pest and insect control and with the entry into force of the Nuclear Non-Proliferation Treaty a Safeguard Analytical Laboratory was established to provide support for the Agency's safeguards inspection responsibilities. Together with WHO a network of 43 Secondary Standard Dosimetry Laboratories were set up in Member States to improve dosimetric accuracy in medicine and radiation protection worldwide. Throughout their history, the laboratories of the IAEA have lent great importance on their training programmes that have enabled many workers in nuclear or nuclear related research to gain experience. This emphasis on training has been stressed particularly to benefit research workers from developing countries

  3. Twenty years of molecular beam epitaxy

    Science.gov (United States)

    Cho, A. Y.

    1995-05-01

    The term "molecular beam epitaxy" (MBE) was first used in one of our crystal growth papers in 1970, after having conducted extensive surface physics studies in the late 1960's of the interaction of atomic and molecular beams with solid surfaces. The unique feature of MBE is the ability to prepare single crystal layers with atomic dimensional precision. MBE sets the standard for epitaxial growth and has made possible semiconductor structures that could not be fabricated with either naturally existing materials or by other crystal growth techniques. MBE led the crystal growth technologies when it prepared the first semiconductor quantum well and superlattice structures that gave unexpected and exciting electrical and optical properties. For example, the discovery of the fractional quantized Hall effect. It brought experimental quantum physics to the classroom, and practically all major universities throughout the world are now equipped with MBE systems. The fundamental principles demonstrated by the MBE growth of III-V compound semiconductors have also been applied to the growth of group IV, II-VI, metal, and insulating materials. For manufacturing, the most important criteria are uniformity, precise control of the device structure, and reproducibility. MBE has produced more lasers (3 to 5 million per month for compact disc application) than any other crystal growth technique in the world. New directions for MBE are to incorporate in-situ, real-time monitoring capabilities so that complex structures can be precisely "engineered". In the future, as environmental concerns increase, the use of toxic arsine and phosphine may be limited. Successful use of valved cracker cells for solid arsenic and phosphorus has already produced InP based injection lasers.

    1993-08-01

    In March 1993, the US Department of Energy, Richland Operations Office (DOE-RL) published its annual Site-Specific Five-Year Plan. The Site-Specific Plan is published to inform the public about the background, status, and plans for Environmental Restoration (ER) and Waste Management (WM) activities at the Hanford site. It is the only document that seeks to bring all ER and WM elements together in one document. The Site-Specific Plan is a companion document to the National Five-Year Plan that deals with all the sites within the DOE complex on a summary level. This Response to Comments document does not try to address every question or concern raised during the public comment period. Some questions were outside the scope of the Five-Year Plan, some we could not decipher, others were variations of the same question. The initial round of public meetings was held in Portland, Oregon, and Seattle, Pasco, and Olympia, Washington. At the request of the Oregon Department of Energy (ODOE) and the Washington State Department of Ecology (Ecology), a second round of meetings was held in Portland and Olympia. Both agencies felt that the first two meetings were held with too little advance notice, and before the Plan could be distributed. Once the public meetings were over and the comment period closed, we then compiled the public comments, largely from audio tapes of the meetings. Individual functions within Hanford were asked to consider and respond to the comments

    A central objective of recent U.S. healthcare policy reform, most notably the Affordable Care Act's (ACA) Health Insurance Marketplace, has been to increase access to stable, affordable health insurance. However, changing market dynamics (rising premiums, changes in issuer participation and plan availability) raise significant concerns about the marketplaces' ability to provide a stable source of healthcare for Americans that rely on them. By looking at the effect of instability on changes in the consumer choice set, we can analyze potential incentives to switch plans among price-sensitive enrollees, which can then be used to inform policy going forward. Data on health plan features for non-tobacco users in 2512 counties in 34 states participating in federally-facilitated exchanges from 2014 to 2016 was obtained from the Centers for Medicaid & Medicare Services. We examined how changes in individual plan features, including premiums, deductibles, issuers, and plan types, impact consumers who had purchased the lowest-cost silver or bronze plan in their county the previous year. We calculated the cost of staying in the same plan versus switching to another plan the following year, and analyzed how costs vary across geographic regions. In most counties in 2015 and 2016 (53.7 and 68.2%, respectively), the lowest-cost silver plan from the previous year was still available, but was no longer the cheapest plan. In these counties, consumers who switched to the new lowest-cost plan would pay less in monthly premiums on average, by $51.48 and $55.01, respectively, compared to staying in the same plan. Despite potential premium savings from switching, however, the majority would still pay higher average premiums compared to the previous year, and most would face higher deductibles and an increased probability of having to change provider networks. While the ACA has shown promise in expanding healthcare access, continued changes in the availability and affordability of health

    The Landlord Program mission is to maintain, preserve, or upgrade the strategic assets of the Hanford Site to meet the overall cleanup mission. This encompasses innovative, appropriate, and cost effective general purpose infrastructure support, services, and long range strategic site planning that is the foundation for seven major Hanford programs. These programs are (1) Environmental Restoration, (2) Tank Waste Remediation System, (3) Solid/Liquid Waste Decontamination, (4) Facility Transition, (5) Spent Fuel, (6) Technology Development, and (7) the Multi-Program Laboratory. General infrastructure support consists of facilities, systems, and equipment that by design or use are not essentially dedicated to a single program mission. Facilities include laboratories, shops, warehouses, and general work space. Systems include electrical, process sewers, rail, roads, telecommunications, water, fire and emergency response, and steam supply and distribution. Funding also supports capital equipment critical to maintaining, upgrading, or operating the general infrastructure. Paramount to these objectives is compliance with all applicable laws, orders, agreements, codes, standards, best management and safety practices. The objectives for general infrastructure support are reflected in five programmatic functions, (1) Program Integration, (2) Capital Equipment, (3) Expense Funded Projects, (4) General Plant Projects, and (5) Line Items

Study’s results in 2011 showed that RHA activities was not maximum that pre-disaster activities should be evaluated. Based on management functions, planning is the very first step. Evaluation of pre-disaster planning is the earliest thing to do to minimize the disasters impact. This study aimed to evaluate activities of floods pre-disaster planning in Bojonegoro year 2014. Data were collected by interview anddocument study. Data were analyzed descriptively. The results showed that based on input components, SOP and facilities had met the standard, while the staff, the type of data, and funds had’nt metthe standard yet. Based on process component, contingency planning had been done according to the standard. Both geomedic mapping and identification of social and economic in the process of activities planning of prevention, mitigation, and disaster response preparedness actions didn’t conduct. Based on the output component, the health department already had a contingency plan, but didn’t have geomedic maps and prevention, mitigation, and disaster response preparedness actions plan. This study concluded that pre-disaster planning activities of Bojonegoro Regency Health Office wasn’t good. The suggestion given are control SOP, increase the staff amount, complete thedata types, allocate funds, make budgettaryplanning, provide vehicles, conduct identification of social and economic, give training to staffs, and make outline of the geomedicmap and prevention, mitigation, and disaster response preparedness actions plan.

    The Columbia River Basin Fish and Wildlife Program Annual Implementation Work Plan (AIWP) for Fiscal Year (FY) 1992 presents Bonneville Power Administration's (BPA) plans for implementing the Columbia River Basin Fish and Wildlife Program (Program) in FY 1992. The AIWP focuses on individual Action Items found in the 1987 Program for which BPA has determined that it has authority and responsibility to implement. Each of the entries in the AIWP includes objectives, background, progress to date in achieving the objectives, and a summary of plans for implementation in FY 1992. Most Action Items are implemented through one or more BPA-funded projects. Each Action Item entry is followed by a list of completed, ongoing, and planned projects, along with objectives, results, schedules, and milestones for each project. In October 1988, BPA and the Columbia Basin Fish and Wildlife Authority (CBFWA) initiated a collaborative and cooperative Implementation Planning Process (IPP). The IPP provided opportunities in FY 1991 for the fish and wildlife agencies. Tribes, and other interested parties to be involved in planning FY 1992 Program implementation. This planing process contributed to the development of this year's AIWP. The joint BPA/CBFWA IPP is expected to continue in FY 1992. The FY 1992 AIWP emphasizes continuation of 143 ongoing, or projected ongoing Program projects, tasks, or task orders, most of which involve protection, mitigation, or enhancement of anadromous fishery resources. The FY 1992 AIWP also contains 10 new Program projects or tasks that are planned to start in FY 1992
