    We conducted syndromic surveillance for the Hokkaido, Japan, Toyako Group of Eight (G8) summit meeting in July 2008 as a counter-measure to bioterrorism attacks and other health emergencies. Surveys were conducted from June 23, two weeks before the summit, to July 23 two weeks after it, with part of those for prescription drugs fully automated, and part by manual input over the World-Wide-Web. Those for ambulance transfer were done similarly. We bought over-the-counter (OTC) sales data from two private research firms in Japan and had the monitor, who had contacts with a private research company, report health conditions via personal computer (PC) or cellphone. We had a virtual conference daily at 9:00 with the local Hokkaido government, local public health center, local Hokkaido public laboratory, the National Institute of Infectious Diseases, and the Ministry of Health, Labor and Welfare to decide whether local public health centers would be required to investigate. Fully automated syndromic surveillance was conducted by 23 pharmacies for prescriptions drugs, and 71 pharmacies provided manual corporate input. One fire department covering Toyako and a VIP support team used fully automated syndromic surveillance and seven Toyako fire departments used manual input. For 79 pharmacies providing OTC sales data, data provision was delayed one day and analysis could not be automated. Four hundred and seventy two households corporate web search for their health conditions. It also automatically analyzed and feed backed. No notable outbreak occurred during the summit, but public health centers investigated seven aberration detected by syndrome surveillance for ambulance transfer. Although a fully automated system was concidered best for early outbreak detection manual input and analysis were also required. Routine, fully automatied syndromic surveillance remains to be realized in Japan.

    In 18 weeks, Health Protection Scotland (HPS) deployed a syndromic surveillance system to early-detect natural or intentional disease outbreaks during the G8 Summit 2005 at Gleneagles, Scotland. The system integrated clinical and non-clinical datasets. Clinical datasets included Accident & Emergency (A&E) syndromes, and General Practice (GPs) codes grouped into syndromes. Non-clinical data included telephone calls to a nurse helpline, laboratory test orders, and hotel staff absenteeism. A cumulative sum-based detection algorithm and a log-linear regression model identified signals in the data. The system had a fax-based track for real-time identification of unusual presentations. Ninety-five signals were triggered by the detection algorithms and four forms were faxed to HPS. Thirteen signals were investigated. The system successfully complemented a traditional surveillance system in identifying a small cluster of gastroenteritis among the police force and triggered interventions to prevent further cases.

    The construct of delivering high-quality and cost-effective health care is in flux, and the profession must strategically plan how to meet the needs of society. In 2006, the House of Delegates of the American Physical Therapy Association passed a motion to convene a summit on "how physical therapists can meet current, evolving, and future societal health care needs." The Physical Therapy and Society Summit (PASS) meeting on February 27-28, 2009, in Leesburg, Virginia, sent a clear message that for physical therapists to be effective and thrive in the health care environment of the future, a paradigm shift is required. During the PASS meeting, participants reframed our traditional focus on the physical therapist and the patient/client (consumer) to one in which physical therapists are an integral part of a collaborative, multidisciplinary health care team with the health care consumer as its focus. The PASS Steering Committee recognized that some of the opportunities that surfaced during the PASS meeting may be disruptive or may not be within the profession's present strategic or tactical plans. Thus, adopting a framework that helps to establish the need for change that is provocative and potentially disruptive to our present care delivery, yet prioritizes opportunities, is a critical and essential step. Each of us in the physical therapy profession must take on post-PASS roles and responsibilities to accomplish the systemic change that is so intimately intertwined with our destiny. This article offers a perspective of the dynamic dialogue and suggestions that emerged from the PASS event, providing further opportunities for discussion and action within our profession.

    The policies of the G8 countries (the G7 industrialized countries plus Russia) matter for population health and the determinants of health worldwide. In the years before the 2005 Summit, relevant G7 commitments were more often broken than kept, representing an inadequate response to the scale of health crises in countries outside the industrialized world. The commitments made in 2005 by some G7 countries to increase development assistance to the longstanding target of 0.7% of Gross National Income, and by the G7 as a whole to additional debt cancellation for some developing countries, were welcome and overdue. However, Canada and the United States did not state timetables for reaching the development assistance target, and new conditionalities attached to debt relief may undermine the benefits for population health. Lack of adequate funding for the Global Fund to Fight AIDS, Tuberculosis and Malaria, even after the September 2005 replenishment meeting, is unconscionable; yet even if those funds were provided, additional resources for developing country health systems would be needed. Similarly, widespread agreement on the need for improving market access for developing country exports was not met with any concrete policy response to the "asymmetrical" nature of recent trade liberalization; neither was the need to control the deadly trade in small arms. To respond adequately to global health needs, the G8 will need to adopt an agenda that more fundamentally alters the distribution of economic and political power, within and among nations.

    Fiber continues to be singled out as a nutrient of public health concern. Adequate intakes of fiber are associated with reduced risk for cardiovascular disease, cancer, diabetes, certain gastrointestinal disorders and obesity. Despite ongoing efforts to promote adequate fiber through increased vegetable, fruit and whole-grain intakes, average fiber consumption has remained flat at approximately half of the recommended daily amounts. Research indicates that consumers report increasingly attempting to add fiber-containing foods, but there is confusion around fiber in whole grains. The persistent and alarmingly low intakes of fiber prompted the "Food & Fiber Summit," which assembled nutrition researchers, educators and communicators to explore fiber's role in public health, current fiber consumption trends and consumer awareness data with the objective of generating opportunities and solutions to help close the fiber gap. The summit outcomes highlight the need to address consumer confusion and improve the understanding of sources of fiber, to recognize the benefits of various types of fibers and to influence future dietary guidance to provide prominence and clarity around meeting daily fiber recommendations through a variety of foods and fiber types. Potential opportunities to increase fiber intake were identified, with emphasis on meal occasions and food categories that offer practical solutions for closing the fiber gap.

    Why do informal, plurilateral summit institutions such as the Group of Eight (G8) major market democracies succeed in advancing costly public health priorities such as maternal, newborn, and child health (MNCH), even when the formal, multilateral United Nations (UN) system fails to meet such goals, when G8 governments afflicted by recession, deficit, and debt seek to cut expenditures, and when the private sector is largely uninvolved, despite the growing popularity of public-private partnerships to meet global health and related nutrition, food, and agriculture needs? Guided by the concert-equality model of G8 governance, this case study of the G8's 2010 Muskoka Initiative on MNCH traces the process through which that initiative was planned within Canada, internationally prepared through negotiations with Canada's G8 partners, produced at Muskoka by the leaders in June, multiplied in its results by the UN summit in September, and reinforced by the new accountability mechanism put in place. It finds that the Muskoka summit succeeded in mobilizing major money and momentum for MNCH. This was due to the initiative and influence of children-focused nongovernmental organizations (NGOs), working with committed individuals and agencies within the host Canadian government, as well as supportive public opinion and the help of those in the UN responsible for realizing its Millennium Development Goals. Also relevant were the democratic like-mindedness of G8 leaders and their African partners, the deference of G8 members to the host's priority, and the need of the G8 to demonstrate its relevance through a division of labor between it and the new Group of Twenty summit. This study shows that G8 summits can succeed in advancing key global health issues without a global shock on the same subject to galvanize agreement and action.

    The delivery of healthcare that meets the requirements for quality, safety and cost-effectiveness relies on a well-trained medical workforce, including clinical academics whose career includes a specific commitment to research, education and/or leadership. In 2011, the Medical Deans of Australia and New Zealand published a review on the clinical academic workforce and recommended the development of an integrated training pathway for clinical academics. A bi-national Summit on Clinical Academic Training was recently convened to bring together all relevant stakeholders to determine how best to do this. An important part understood the lessons learnt from the UK experience after 10 years since the introduction of an integrated training pathway. The outcome of the summit was to endorse strongly the recommendations of the medical deans. A steering committee has been established to identify further stakeholders, solicit more information from stakeholder organisations, convene a follow-up summit meeting in late 2015, recruit pilot host institutions and engage the government and future funders.

    The American Association of Sleep Technologists (AAST) Board of Directors hosted a Sleep Technology Summit on September 21, 2013 with the goals of identifying changes in the delivery of diagnostic and treatment services to sleep disorders patients, predicting the impact on sleep technologists, identifying new roles for sleep technologists, and determining appropriate education to prepare technologists for the future. A carefully chosen panel of speakers focused on the business skills necessary to provide care cost effectively and the clinical skills that will be essential for the technologist of the future to help care for patients with sleep disorders. A group of selected leaders, educators, and industry professionals reviewed the current state of affairs and examined opportunities to sustain the profession and define the role of the sleep technologist of the future. Facilitated group discussions of these critical topics followed each session. There was a clear consensus that regulatory and economic pressures are changing the way sleep disorders patients are diagnosed and treated. Private insurers are requiring pre-authorization for laboratory sleep studies and are incentivizing home sleep testing for most patients suspected of obstructive sleep apnea. Reimbursement for home testing will be lower than for laboratory testing, and further reductions in overall reimbursement are anticipated. These factors will almost certainly reduce the need for technologists to perform laboratory diagnostic studies and pressure sleep centers to reduce payrolls. Remaining laboratory patients will have more complicated sleep disorders, have more comorbidity, and require a higher level of care than most of the patients currently tested in sleep centers. Testing these patients will require technologists with a higher level of training, experience, and sophistication. A second area of consensus was that the focus in medicine is changing from diagnosis to outcomes. New models of

    The Medical Informatics and Health Care Systems group in the Office of Space Medicine at NASA Johnson Space Center (JSC) has been tasked by NASA with improving overall medical care on the International Space Station (ISS) and providing insights for medical care for future exploration missions. To accomplish this task, a three day Operational and Research Musculoskeletal Summit was held on August 23-25th, 2005 at Space Center Houston. The purpose of the summit was to review NASA#s a) current strategy for preflight health maintenance and injury screening, b) current treatment methods in-flight, and c) risk mitigation strategy for musculoskeletal injuries or syndromes that could occur or impact the mission. Additionally, summit participants provided a list of research topics NASA should consider to mitigate risks to astronaut health. Prior to the summit, participants participated in a web-based pre-summit forum to review the NASA Space Medical Conditions List (SMCL) of musculoskeletal conditions that may occur on ISS as well as the resources currently available to treat them. Data from the participants were compiled and integrated with the summit proceedings. Summit participants included experts from the extramural physician and researcher communities, and representatives from NASA Headquarters, the astronaut corps, JSC Medical Operations and Human Adaptations and Countermeasures Offices, Glenn Research Center Human Research Office, and the Astronaut Strength, Conditioning, and Reconditioning (ASCR) group. The recommendations in this document are based on a summary of summit discussions and the best possible evidence-based recommendations for musculoskeletal care for astronauts while on the ISS, and include recommendati ons for exploration class missions.

  3. It's a long way to Auchterarder! 'Negotiated management' and mismanagement in the policing of G8 protests.

    PubMed

    Gorringe, Hugo; Rosie, Michael

    2008-06-01

    Recent analyses of protest policing in Western democracies argue that there has been a marked shift away from oppressive or coercive approaches to an emphasis on consensus based negotiation. King and Waddington (2005) amongst others, however, suggest that the policing of international summits may be an exception to this rule. This paper examines protest policing in relation to the 2005 G8 summit in Gleneagles, Scotland. We argue that 'negotiated management' cannot be imported wholesale as a policing strategy. Rather it is mediated by local history, forms of police knowledge and modes of engagement. Drawing on interviews and participant observation we show that 'negotiated management' works best when both sides are committed to negotiation and that police stereotyping or protestor intransigence can lead to the escalation of any given event. In closing we note the new challenges posed by forms of 'global' protest and consider the implications for future policing of protest. PMID:18498591

    One of the most persistent and controversial issues facing the global community is climate change. With the creation of the UN Framework Convention on Climate Change (UNFCCC) in 1992 and the Kyoto Protocol (1997), the global community established some common ground on how to address this issue. However, the last several climate summits have failed…

    Abstract The CARICOM Summit on Chronic Non-Communicable Diseases – the first government summit ever devoted to noncommunicable diseases (NCDs) – was convened by the Caribbean Community (CARICOM) in Trinidad and Tobago in September 2007. Leaders in attendance issued the declaration of Port of Spain, a call for the prevention and control of four major NCDs and their risk factors. An accountability instrument for monitoring compliance with summit commitments was developed for CARICOM by the University of the West Indies in 2008 and revised in 2010. The instrument – a one-page colour-coded grid with 26 progress indicators – is updated annually by focal points in Caribbean health ministries, verified by each country’s chief medical officer and presented to the annual Caucus of Caribbean Community Ministers of Health. In this study, the G8 Research Group’s methods for assessing compliance were applied to the 2009 reporting grid to assess each country’s performance. Given the success of the CARICOM Summit, a United Nations high-level meeting of the General Assembly on the prevention and control of NCDs was held in September 2011. In May 2013 the World Health Assembly adopted nine global targets and 25 indicators to measure progress in NCD control. This study shows that the CARICOM monitoring grid can be used to document progress on such indicators quickly and comprehensibly. An annual reporting mechanism is essential to encourage steady progress and highlight areas needing correction. This paper underscores the importance of accountability mechanisms for encouraging and monitoring compliance with the collective political commitments acquired at the highest level. PMID:24700994

    An unrecognized affliction is striking certain gifted performers at the top of their game. Its cause, paradoxically, is success itself. These stars, who thrive on conquering new challenges, can lose their bearings and question their purpose once a job has been mastered. A vague dissatisfaction gives way to confusion and then to inner turmoil. Left unattended, this summit syndrome can derail promising careers. The syndrome has three phases. In the approach phase, when most of the challenges of a current job have been met, sufferers tend to push harder in a vain attempt to recapture the adrenaline rush of the climb. Then, in the plateauing phase, when virtually all the challenges have been conquered, these individuals, who are incapable of coasting, bear down to try to produce ever more stellar results, but to less effect and greater dissatisfaction. This leads to the terminal descending phase, when performance slips noticeably. As their superstar status fades, they jump ship, accept demotions, or take lateral transfers. It's a terrible waste, for if the syndrome is recognized, steps can be taken before performance slips to dispel the confusion and set the stage for productive growth to the next assignment. There are four parts to this process: First, understand your "winning formula"--the characteristic way you approach a situation--and the vital part it plays in feeling stale or losing your edge. Second, reconnect with your core purpose in life. Third, recast your current, or future, job to better align your inner aspirations with the external requirements of your work. And fourth, create a developmental path by honing a handful of core leadership competencies. None of this is easy, but for talented individuals--and the organizations that rely on them--the vaccine of preventive awareness is far better than gambling on an after-the-fact cure once the crisis is full-blown.

    A mouse monoclonal antibody (MAb) was generated against swine leukocyte antigen (SLA) class I alpha chain. A newly developed series of MAb clones that react with pan leukocytes were selected and tested by immuno-histochemistry using SLA class I alpha chain expressing Cos-7 cells. Among them, MAb 4G8 was characterized by the following features: (1) 4G8 reacted with Cos-7 cells transfected with SLA class I alpha chain from the d haplotype, (2) 4G8 recognized epitopes that were different from those of commercially available anti-SLA class I MAbs 74-11-10 and PT85A, and (3) 4G8 could be used to immunostain frozen sections of thymus, spleen, lymph node, kidney, and liver tissues with good results.

  9. Beyond the World Food Summit.

    While most speakers at the 1996 World Food Summit expressed concern about the injustice that forces more than 800 million people worldwide to live with hunger, some sought solutions through economic and social development while others called for a more liberal marketplace. Among world leaders, only Fidel Castro raised issues and challenges that addressed some of the underlying causes of malnutrition. The Plan of Action that grew out of the Summit has only one measurable commitment, which is to halve the number of undernourished people by 2015. The other six commitments, while diluted, contain important objectives even though they give little emphasis to the underlying causes of poverty or hunger. The Summit process, however, did contribute to the fact that food-related issues are now placed higher on the world agenda because many of these issue were raised by civil service organizations (CSOs) at the Summit's parallel NGO (nongovernmental organization) forum. In fact, one of the most positive outcomes of the Summit may prove to be the increased effectiveness of the CSOs as a result of the creation of improved networks in preparation for the Summit. The CSOs contributed examples of how food security could be improved, published an active site on the World Wide Web, and challenged the statements of governments. In addition to raising trade issues, CSOs also lobbied for sustainable agriculture and agricultural biodiversity. In fact, CSOs may have to set a new action agenda for the formal sector to encourage development of new institutions and new global forums that give NGOs a place at the table. PMID:12348317

    Background and Problem Definition: To evaluate NASA s current standards and practices related to atrial arrhythmias in astronauts, Space Medicine s Advanced Projects Section at the Johnson Space Center was tasked with organizing a summit to discuss the approach to atrial arrhythmias in the astronaut cohort. Since 1959, 11 cases of atrial fibrillation, atrial flutter, or supraventricular tachycardia have been recorded among active corps crewmembers. Most of the cases were paroxysmal, although a few were sustained. While most of the affected crewmembers were asymptomatic, those slated for long-duration space flight underwent radiofrequency ablation treatment to prevent further episodes of the arrhythmia. The summit was convened to solicit expert opinion on screening, diagnosis, and treatment options, to identify gaps in knowledge, and to propose relevant research initiatives. Summit Meeting Objectives: The Atrial Arrhythmia Summit brought together a panel of six cardiologists, including nationally and internationally renowned leaders in cardiac electrophysiology, exercise physiology, and space flight cardiovascular physiology. The primary objectives of the summit discussions were to evaluate cases of atrial arrhythmia in the astronaut population, to understand the factors that may predispose an individual to this condition, to understand NASA s current capabilities for screening, diagnosis, and treatment, to discuss the risks associated with treatment of crewmembers assigned to long-duration missions or extravehicular activities, and to discuss recommendations for prevention or management of future cases. Summary of Recommendations: The summit panel s recommendations were grouped into seven categories: Epidemiology, Screening, Standards and Selection, Treatment of Atrial Fibrillation Manifesting Preflight, Atrial Fibrillation during Flight, Prevention of Atrial Fibrillation, and Future Research

    Central nervous system (CNS) diseases and, in particular, mental health disorders, are becoming recognized as the health challenge of the 21(st) century. Currently, at least 10% of the global population is affected by a mental health disorder, a figure that is set to increase year on year. Meanwhile, the rate of development of new CNS drugs has not increased for many years, despite unprecedented levels of investment. In response to this state of affairs, the Collegium Internationale Neuro-Psychopharmacologicum (CINP) convened a summit to discuss ways to reverse this disturbing trend through new partnerships to accelerate CNS drug discovery. The objectives of the Summit were to explore the issues affecting the value chain (i.e. the chain of activities or stakeholders that a company engages in/with to deliver a product to market) in brain research, thereby gaining insights from key stakeholders and developing actions to address unmet needs; to identify achievable objectives to address the issues; to develop action plans to bring about measurable improvements across the value chain and accelerate CNS drug discovery; and finally, to communicate recommendations to governments, the research and development community, and other relevant stakeholders. Summit outputs include the following action plans, aligned to the pressure points within the brain research-drug development value chain: Code of conduct dealing with conflict of interest issues, Prevention, early diagnosis, and treatment, Linking science and regulation, Patient involvement in trial design, definition of endpoints, etc., Novel trial design, Reproduction and confirmation of data, Update of intellectual property (IP) laws to facilitate repurposing and combination therapy (low priority), Large-scale, global patient registries, Editorials on nomenclature, biomarkers, and diagnostic tools, and Public awareness, with brain disease advocates to attend G8 meetings and World Economic Forum (WEF) Annual meetings in

  16. Foreign policy matters: a normative view of the G8 and population health.

    PubMed

    Labonte, Ronald; Schrecker, Ted

    2007-03-01

    The Group of Eight (G8) countries occupy a dominant position in the international economic and political order. Given what is known about influences on the social determinants of health in an interconnected world, the G8 are a logical starting point for any enquiry into the relations between foreign policy and health. We first make five arguments for adopting an explicitly normative, equity-oriented perspective on the performance of G8 policy in areas related to population health. We then examine G8 performance with respect to the crucial policy triad of development assistance, debt relief and trade, finding that neither rhetoric nor promising institutional innovation has been matched by resources commensurate with demonstrated levels of need. We conclude that it is necessary to pursue advocacy efforts based on the normative perspective we have put forward and that doing so effectively requires further investigation of why some policies are more receptive than others to policies of redistribution both within and outside their borders.

    Human G8 Rotavirus A (RVA) strains are commonly detected in Africa but are rarely detected in Japan and elsewhere in the world. In this study, the whole genome sequence of the first human G8 RVA strain designated AU109 isolated in a child with acute gastroenteritis in 1994 was determined in order to understand how the strain was generated including the host species origin of its genes. The genotype constellation of AU109 was G8-P[4]-I2-R2-C2-M2-A2-N2-T2-E2-H2. Phylogenetic analyses of the 11 genome segments revealed that its VP7 and VP1 genes were closely related to those of a Hungarian human G8P[14] RVA strain and these genes shared the most recent common ancestors in 1988 and 1982, respectively. AU109 possessed an NSP2 gene closely related to those of Chinese sheep and goat RVA strains. The remaining eight genome segments were closely related to Japanese human G2P[4] strains which circulated around 1985-1990. Bayesian evolutionary analyses revealed that the NSP2 gene of AU109 and those of the Chinese sheep and goat RVA strains diverged from a common ancestor around 1937. In conclusion, AU109 was generated through genetic reassortment event where Japanese DS-1-like G2P[4] strains circulating around 1985-1990 obtained the VP7, VP1 and NSP2 genes from unknown ruminant G8 RVA strains. These observations highlight the need for comprehensive examination of the whole genomes of RVA strains of less explored host species.

    We present a detailed analysis of the GeV gamma-ray emission toward the supernova remnant (SNR) G8.7-0.1 with the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope. An investigation of the relationship between G8.7-0.1 and the TeV unidentified source HESS J1804-216 provides us with an important clue on diffusion process of cosmic rays if particle acceleration operates in the SNR. The GeV gamma-ray emission is extended with most of the emission in positional coincidence with the SNR G8.7-0.1 and a lesser part located outside the western boundary of G8.7-0.1. The region of the gamma-ray emission overlaps spatially connected molecular clouds, implying a physical connection for the gamma-ray structure. The total gamma-ray spectrum measured with LAT from 200 MeV-100 GeV can be described by a broken power-law function with a break of 2.4 {+-} 0.6 (stat) {+-} 1.2 (sys) GeV, and photon indices of 2.10 {+-} 0.06 (stat) {+-} 0.10 (sys) below the break and 2.70 {+-} 0.12 (stat) {+-} 0.14 (sys) above the break. Given the spatial association among the gamma rays, the radio emission of G8.7-0.1, and the molecular clouds, the decay of p0s produced by particles accelerated in the SNR and hitting the molecular clouds naturally explains the GeV gamma-ray spectrum. We also find that the GeV morphology is not well represented by the TeV emission from HESS J1804-216 and that the spectrum in the GeV band is not consistent with the extrapolation of the TeV gamma-ray spectrum. The spectral index of the TeV emission is consistent with the particle spectral index predicted by a theory that assumes energy-dependent diffusion of particles accelerated in an SNR. We discuss the possibility that the TeV spectrum originates from the interaction of particles accelerated in G8.7-0.1 with molecular clouds, and we constrain the diffusion coefficient of the particles.

An investigation of the relationship between G8.7-0.1 and the TeV unidentified source HESS J1804-216 provides us with an important clue on diffusion process of cosmic rays if particle acceleration operates in the SNR. The GeV gamma-ray emission is extended with most of the emission in positional coincidence with the SNR G8.7-0.1 and a lesser part located outside the western boundary of G8.7-0.1. The region of the gamma-ray emission overlaps spatially connected molecular clouds, implying a physical connection for the gamma-ray structure. The total gamma-ray spectrum measured with LAT from 200 MeV-100 GeV can be described by a broken power-law function with a break of 2.4 {+-} 0.6 (stat) {+-} 1.2 (sys) GeV, and photon indices of 2.10 {+-} 0.06 (stat) {+-} 0.10 (sys) below the break and 2.70 {+-} 0.12 (stat) {+-} 0.14 (sys) above the break. Given the spatial association among the gamma rays, the radio emission of G8.7-0.1, and the molecular clouds, the decay of {pi}{sup 0}s produced by particles accelerated in the SNR and hitting the molecular clouds naturally explains the GeV gamma-ray spectrum. We also find that the GeV morphology is not well represented by the TeV emission from HESS J1804-216 and that the spectrum in the GeV band is not consistent with the extrapolation of the TeV gamma-ray spectrum. The spectral index of the TeV emission is consistent with the particle spectral index predicted by a theory that assumes energy-dependent diffusion of particles accelerated in an SNR. We discuss the possibility that the TeV spectrum originates from the interaction of particles accelerated in G8.7-0.1 with molecular clouds, and we constrain the diffusion coefficient of the particles.

    The Summit Members' Working Group on Controlled Thermonuclear Fusion (Fusion Working Group (FWG)) was established in 1983 in response to the Declaration of the Heads of State and Government at the Versailles Economic Summit meeting of 1982, and in response to the subsequent report of the Working Group in Technology, Growth and Employment (TGE) as endorsed at the Williamsburg Summit meeting, 1983. This document contains the complete written record of each of the three FWG meetings which include the minutes, lists of attendees, agendas, statements, and summary conclusions as well as the full reports of the Technical Working Party. In addition, there is a pertinent exchange of correspondence between FWG members on the role of the Technical Working Party and a requested background paper on the modalities associated with a possible future ETR project.

    As the first Meeting Chairman for the Spring and Fall meetings, Martin Walt has achieved notable success in realizing the many goals set forth by the Union for its annual meetings. Under his guidance, the Meeting Program Committee has been able to reduce the number of conflicting sessions and provide for the presentation of well-organized and effectively displayed poster sessions. The early planning of Union sessions and the introduction of ‘mini-frontiers,’ along with careful scheduling, has provided an increased opportunity for participation. A record high of 2785 registrants was recorded during the 1981 Fall Meeting, topping very slightly the old record of 2775 for the 1974 Spring Meeting.

    Group A rotaviruses (RVAs) are enteric pathogens with well-documented zoonotic transmissions to humans. The segmented genome of the virus enables reassortment events which might alter host susceptibility and/or disease course. Genetic analysis of rotavirus in dogs has so far only revealed RVAs with the VP7 and VP4 genome constellation G3P[3]. RVA G3P[3] have also been found in cats, humans, monkeys and bats. In the present study, we described an unusual RVA of genotype G8P[1] which was isolated from an asymptomatically infected young dog. The dog did not show signs of diarrhoea. Analysis of full-length segments of VP2, VP6 and VP7 as well as NSP1-NSP5 revealed a typical bovine-like genotype constellation G8-P[1]-I2-Rx-C2-Mx-A3-N2-T6-E2-H3. Phylogenetic analysis supported the hypothesis of an interspecies transmission from a bovine/artiodactyl species or from humans to the young dog. The isolate was likely to represent a multiple reassortant virus. PMID:25304653

    Across Europe, the role of the welfare state is constantly being questioned and even eroded. At the same time, funding sources for post-graduate medical education and training are under attack as regulators review the working relationships between physicians and industry. Both of these issues have profound consequences for cardiologists and their patients, and were, therefore, chosen as the themes of the European Heart Rhythm Association (EHRA) 2014 Spring Summit held at Heart House, Sophia Antipolis, 25-26 March 2014. The meeting noted that some of the changes are already affecting patient care standards and that this is exacerbated by a reduction in research and education programmes. The principle conclusion was that EHRA must find better means of engagement with the authorities across Europe to ensure that its views are considered and that ethical patient care is preserved. Participants were particularly alarmed by the example from Sweden in which future healthcare planning appears to exclude the views of physicians, although this is not yet the case in other countries. The demand for greater transparency in relationships between physicians and industry was also discussed. Although intended to eliminate corruption, concern was expressed that such moves would cause long-term damage to education and research, threatening the future of congresses, whose role in these areas appears underestimated by the authorities.

    “We understand from the science that we have no choice between mitigation and adaptation. We have to do both,” John Holdren, President Barack Obama's science and technology advisor, said at a 29 September meeting where he was presented with a new report about national and regional preparations for adapting to changing climate. The report is based on the National Climate Adaptation Summit, which was convened by the University Corporation for Atmospheric Research in May 2010. Stating that the United States must adapt to a changing climate now and prepare for increasing impacts on urban infrastructure, food, water, human health, and ecosystems in the coming decades, the report identifies a set of priorities for near-term action. Among the priorities are developing an overarching national strategy, with research, planning, and management components to guide federal climate change adaptation programs. Other priorities include improving coordination of federal plans and programs and creating a federal climate information portal and a clearinghouse of best practices and tool kits for adaptation. The report also identifies other priorities, including the need for support for assessments in the U.S. Global Change Research Program agency budgets, for increasing funding for research on vulnerability and impacts, and for initiating a regional series of ongoing climate adaptation forums.

    This study analyzed eleven genomic segments of three Korean porcine G8P[7] group A rotavirus (RVA) strains. Phylogenetically, these strains contained two bovine-like and nine porcine-like genomic segments. Eight genes (VP1, VP2, VP6 and NSP1-NSP5) of strains 156-1 and 42-1 and seven genes (VP1, VP2, VP6 and NSP2-NSP5) of strain C-1 clustered closely with porcine and porcine-like animal strains and distantly from typical human Wa-like strains. The VP3-M2 genotype of these strains clustered closely with bovine-like strains, but distantly with typical human DS-1-like strains. These data indicate that multiple reassortments involving porcine and bovine RVA strains in Korea must have occurred. PMID:27393603

    Bold scarps and extensional features (grabens) record multiple stages of caldera collapse at the summit of Olympus Mons. The wrinkle ridges are contractional features, and probably formed during the cooling of an ancient lava lake, prior to the collapse events. Olympus Mons is the largest volcano in our solar system, reaching heights of over 40 km tall from base to summit, with the base covering an area as large as the state of Arizona.

    RotaTeqTM is a pentavalent rotavirus vaccine based on a bovine rotavirus genetic backbone in vitro reassorted with human outer capsid genes. During clinical trials of RotaTeqTM in Sub-Saharan Africa, the vaccine efficacy over a 2-year follow-up was lower against the genotypes contained in the vaccine than against the heterotypic G8P[6] and G8P[1] rotavirus strains of which the former is highly prevalent in Africa. Complete genome analyses of 43 complete rotavirus genomes collected during phase III clinical trials of RotaTeqTM in Sub-Saharan Africa, were conducted to gain insight into the high level of cross-protection afforded by RotaTeqTM against these G8 strains. Phylogenetic analysis revealed the presence of a high number of bovine rotavirus gene segments in these human G8 strains. In addition, we performed an in depth analysis on the individual amino acid level which showed that G8 rotaviruses were more similar to the RotaTeqTM vaccine than non-G8 strains. Because RotaTeqTM possesses a bovine genetic backbone, the high vaccine efficacy against G8 strains might be partially explained by the fact that all these strains contain a complete or partial bovine-like backbone. Altogether, this study supports the hypothesis that gene segments other than VP7 and VP4 play a role in vaccine-induced immunity.

    This special section highlights some of the important work presented at the Breath Analysis Summit 2011, which was held in Parma (Italy) from 11 to 14 September 2011. The meeting, which was jointly organized by the International Association for Breath Research and the University of Parma, was attended by more than 250 delegates from 33 countries, and offered 34 invited lectures and 64 unsolicited scientific contributions. The summit was organized to provide a forum to scientists, engineers and clinicians to present their latest findings and to meet industry executives and entrepreneurs to discuss key trends, future directions and technologies available for breath analysis. A major focus was on nitric oxide, exhaled breath condensate, electronic nose, mass spectrometry and newer sensor technologies. Medical applications ranged from asthma and other respiratory diseases to gastrointestinal disease, occupational diseases, critical care and cancer. Most people identify breath tests with breathalysers used by police to estimate ethanol concentration in blood. However, breath testing has far more sophisticated applications. Breath analysis is rapidly evolving as a new frontier in medical testing for disease states in the lung and beyond. Every individual has a breath fingerprint-or 'breathprint'-that can provide useful information about his or her state of health. This breathprint comprises the many thousands of molecules that are expelled with each breath we exhale. Breath research in the past few years has uncovered the scientific and molecular basis for such clinical observations. Relying on mass spectrometry, we have been able to identify many such unique substances in exhaled breath, including gases, such as nitric oxide (NO) and carbon monoxide (CO), and a wide array of volatile organic compounds. Exhaled breath also carries aerosolized droplets that can be collected as an exhaled breath condensate that contains endogenously produced non-volatile compounds. Breath

The process began with the adoption of Resolution 321 (A-08) at an AMA Annual House of Delegates meeting in June 2008. Resolution 321 (A-08) states, in part, that "...the AMA encourages relevant specialties to collaborate in studying: 1) the scope and practice and body of knowledge encompassed by the field of Pain Medicine; 2) the adequacy of undergraduate, graduate, and post graduate education in the principles and practices of the field of Pain Medicine, considering the current and anticipated medical need for the delivery of quality pain care; and 3) appropriate training and credentialing criteria for this multi-disciplinary field of medical practice." The next step was delegating the responsibility for implementing Resolution 321 (A-08) to the Pain and Palliative Medicine Specialty Section Council (PPMSSC). The PPMSSC, under the direction of its chairman, Philipp M. Lippe, MD, FACS, assumed responsibility in November 2008 for identifying a process that would achieve the goals established by Resolution 321 (A-08). The PPMSSC in turn established an Advisory Committee, charged with strategic planning, and an Implementation Committee, charged with tactical operations. The two groups began work immediately. The process included three distinct phases centered on a Pain Medicine Summit. Phase One involved a modified Delphi process identifying the five most pressing and relevant themes in pain care. Phase Two consisted of the Pain Medicine Summit itself, including a gathering of representatives from across the pain care spectrum to address the previously identified five most pressing themes. Phase Three was the preparation of this report, which describes the conclusions drawn and recommendations developed by the attendees at the Pain Medicine Summit.

    The Mushroom Council convened the Mushrooms and Health Summit in Washington, DC, on 9-10 September 2013. The proceedings are synthesized in this article. Although mushrooms have long been regarded as health-promoting foods, research specific to their role in a healthful diet and in health promotion has advanced in the past decade. The earliest mushroom cultivation was documented in China, which remains among the top global mushroom producers, along with the United States, Italy, The Netherlands, and Poland. Although considered a vegetable in dietary advice, mushrooms are fungi, set apart by vitamin B-12 in very low quantity but in the same form found in meat, ergosterol converted with UV light to vitamin D2, and conjugated linoleic acid.

    The Mushroom Council convened the Mushrooms and Health Summit in Washington, DC, on 9-10 September 2013. The proceedings are synthesized in this article. Although mushrooms have long been regarded as health-promoting foods, research specific to their role in a healthful diet and in health promotion has advanced in the past decade. The earliest mushroom cultivation was documented in China, which remains among the top global mushroom producers, along with the United States, Italy, The Netherlands, and Poland.

    Ultrasound (US) is a widely used imaging modality throughout the world, yet differences in usage remain among countries or regions, according to the results of the International Summit, organised by the ESR during the European Congress of Radiology last March in Vienna. The International Summit is held each year by the ESR and its partner national and international societies of radiology from outside Europe with the primary goal of gathering information about a particular topic in radiology from a worldwide perspective. In 2014, some aspects of the practice of US imaging within and outside radiology were discussed, following a list of items prepared by the ESR Working Group on Ultrasound. Results showed that radiological US has similar problems throughout the world. At the same time, however, there are profound differences in how US is practised and the results of this meeting should be considered with caution. The results of the International Summit offer an overview of the major trends and differences in the use of US worldwide, but as a whole suggest that this imaging technique still plays a major role in radiology and health care.Main messages• US is a widely used modality and constitutes a great part of radiological workload.• The use of ultrasound is split between radiological and non-radiological services.• Training differs among countries and the presence of local subspecialty societies improves training quality.• The shortage of local radiologists and lack of interest among young radiologists are worrying.• US use should not be limited to radiologists alone, especially in sparsely populated areas.

    A series of novel anion exchange composite membrane (QCS/PS-G8-2-8) were synthesized based on the quaternized chitosan (QCS, DQ = 89.20 (±3.50)%) blended with block polymer of polystyrene (PS) and G8-2-8 (maleic acid diethyl brace base pairs [octyl dimethyl chloride/ammonium bromide]). Then the QCS was cross-linked by glutaraldehyde (GA). The parameters including adsorption time (t), pH, and initial concentration of Rhodamine B (C0), temperature (T), the mass fraction of G8-2-8 and GA (WGA) on the adsorption were investigated to determine the optimum condition for the removal of RB. The kinetic and thermodynamic properties of the adsorption process were also discussed. The optimum adsorption condition was that the adsorption time was 100 min, pH was 4, the initial concentration of RB was 100 mg L-1, the mass fraction of G8-2-8 was 5.0 wt%, the mass fraction of GA was 2.0 wt%, the temperature was 40 °C. Thus, RB optimum adsorption capacity (q) of the composite membrane QCS/PS-G8-2-8 (5.0%) (G8-2-8 mass content (wt.%) was 5.0%) was 17.04 mg g-1. The adsorption isotherm of the RB on the composite membrane can be well fitted with the Temkin equation. The adsorption kinetics can be well described by the pseudo-second-order kinetics model. The values of ΔG, ΔH and ΔS indicated that the adsorption of RB onto QCS/PS-G8-2-8 was spontaneous and exothermic.

    SUMMiT (Sandia Ultra-planar Multi-level MEMS Technology) at the Sandia National Laboratories' MDL (Microelectronics Development Laboratory) is a standardized MEMS (Microelectromechanical Systems) technology that allows designers to fabricate concept prototypes. This technology provides four polysilicon layers plus three sacrificial oxide layers (with the third oxide layer being planarized) to enable fabrication of complex mechanical systems-on-a-chip. Quantified reproducibility of the SUMMiT process is important for process engineers as well as designers. Summary statistics for critical MEMS technology parameters such as film thickness, line width, and sheet resistance will be reported for the SUMMiT process. Additionally, data from Van der Pauw test structures will be presented. Data on film thickness, film uniformity and critical dimensions of etched line widths are collected from both process and monitor wafers during manufacturing using film thickness metrology tools and SEM tools. A standardized diagnostic module is included in each SWiT run to obtain post-processing parametric data to monitor run-to-run reproducibility such as Van der Pauw structures for measuring sheet resistance. This characterization of the SUMMiT process enables design for manufacturability in the SUMMiT technology.

    During the COP15 climate summit meeting a physical and virtual installation of time was performed at a linear scale of 1 mm per 100 years. The "track of time" was carefully anchored geographically so that highlights in time history coincided with landmarks of historical and cultural significance to both tourists and the local Danish population; with Big Bang at the site of early royal settlements from the Viking age (13.7 billion years ~ 137 km from now), Earth origin at Kronborg in Elsinore (4.6 bil. Years ~ 46 km), and fish go on land at The Little Mermaid (390 mil. Years ~ 3900 m). The venue of the COP15 meeting coincided with the position of severe global warming, driven by the steady solar constant increase, to be expected 600 million years into the future. Nested in this grand track of time were the Quaternary ice-ages (2.6 mil. years ~ 26 m), human origin as species (100,000 years ~ 1 m), human history (< 10,000 years ~ 100 mm), personal life and the scope of political consequences of voting action (100 years ~ 1 mm). This installation of time involved several media. Highlights in time history and future were installed as a kml-file so that the convenient user interface of Google Earth could be utilized to provide both overview of time and understanding of details and proportions events antropo-geo-cosmo-history. Each Google Earth marker-balloon gave short explanations and linked to "on location" video-narratives. A classical printed text-folder was prepared as a tour guide for those who wanted to actually walk the Phanerozoic (~5 km). Credit-card-shaped graphs of temperature, CO2 and sealevel development and scenarios were prepared to scale for the period 4000 BP to 1000 years into the future. Along the time line from "Fish on land" to the present 3900 chalk marks were placed on the street surface, one for every metre = time span of Man as a species so far. A "NowGate" marking the present was implemented physically as a door frame, where citizens could meet

    In June 2007, representatives from federal, state, and academic institutions met to discuss the role of innovative science, technology, and policy in meeting future energy and water demands in the Snake-Columbia River Basin. Conference members assessed the state-of-the-science, technology, and associated research to develop cost-effective and environmentally sound methodologies and technologies to maximize the production of energy and availability of water and to minimize the consumption of both water and energy in the Snake-Columbia River system. Information on all phases of science and technology development, theoretical analysis, laboratory experiments, pilot tests, and field applications were relevant topics for discussion. An overview of current management needs was presented the first day. On the second day, five focus groups were created: ? Energy Generation and Use ? Water Allocation and Use ? Energy/Water Storage ? Environmental Considerations ? Social, Economic, Political, and Regulatory Considerations. Each group started with a list of status items and trends, and discussed the future challenges and research needed to reach four goals: ? Balance energy production and resource consumption ? Balance water availability and competing needs ? Balance water consumption/energy production and competing needs ? Balance environmental impacts and water use/energy production ? Balance costs and benefits of water use. The resulting initiatives were further broken down into three categories of importance: critical, important, and nice to do but could be delayed. Each initiative was assigned a number of dots to show a more refined ranking. The results of each focus group are given in the pages that follow. These results are intended to help local and regional researchers 1.

    There is no place on Earth like the Galapagos Islands and no better destination to discuss the reality of evolution. Under the theme ‘Why Does Evolution Matter’, the University San Francisco of Quito (USFQ), Ecuador, and its Galapagos Institute for the Arts and Sciences (GAIAS), organized the III World Evolution Summit in San Cristóbal Island. The 200-attendee meeting took place on 1 to 5 June 2013; it included 12 keynote speakers, 20 oral presentations by international scholars, and 31 posters by faculty, postdocs, and graduate and undergraduate students. The Summit encompassed five sessions: evolution and society, pre-cellular evolution and the RNA world, behavior and environment, genome, and microbes and diseases. USFQ and GAIAS launched officially the Lynn Margulis Center for Evolutionary Biology and showcased the Galapagos Science Center, in San Cristóbal, an impressive research facility conceptualized in partnership with the University of North Carolina at Chapel Hill, USA. USFQ and GAIAS excelled at managing the conference with exceptional vision and at highlighting the relevance of Galapagos in the history of modern evolutionary thinking; Charles Darwin’s visit to this volcanic archipelago in 1835 unfolded unprecedented scientific interest in what today is a matchless World Heritage.

    The first Chile-U.S. Astronomy Education Outreach Summit occurred March 22-28, 2015. The Summit was organized and supported by the U.S. Embassy in Chile, Associated Universities Inc., Association of Universities for Research in Astronomy, the Carnegie Institution for Science, the Image of Chile Foundation, the National Science Foundation, and La Comisión Nacional de Investigación Científica y Tecnológica. The Summit brought together a team of leading experts and officials from Chile and the U.S. to share best practices in astronomy education and outreach. In addition, Summit participants discussed enhancing existing partnerships, and building new collaborations between U.S. Observatories and astronomy education outreach leaders in Chile.The Summit was an exciting and intense week of work and travel. Discussions opened in Santiago on March 22 with a variety of astronomy education and public outreach work sessions, a public forum, and on March 23 the U.S. Embassy sponsored a Star Party. On Tuesday, March 24, the Summit moved to San Pedro de Atacama, where activities included work sessions, a visit to the Atacama Large Millimeter/Submillimeter Array telescope facilities, and a second public forum. From San Pedro, the team traveled to La Serena for additional work sessions, visits to Gemini and Cerro Tololo, a third public forum, and the closing session. At each stop, authorities and the broader community were invited to participate and provide valuable input on the current state, and the future, of astronomy education and public outreach.Following the Summit a core working committee has continued meeting to draft a “roadmap document” based on findings from the Summit. This document will help to identify potential gaps in astronomy outreach efforts, and how the U.S. facilities and Chilean institutions might work together strategically to address these needs. The first draft of this “roadmap document” will be made available for comment in both Spanish and

    Since 2007, the Italian Rotavirus Surveillance Program (RotaNet-Italy) has monitored the diversity and distribution of genotypes identified in children hospitalized with rotavirus acute gastroenteritis. We report the genomic characterization of two rare human G8P[14] rotavirus strains, identified in two children hospitalized with acute gastroenteritis in the southern Italian region of Apulia during rotavirus strain surveillance in 2012. Both strains showed a G8-P[14]-I2-R2-C2-M2-A11-N2-T6-E2-H3 genomic constellation (DS-1-like genomic background). Phylogenetic analysis of each genome segment revealed a mixed configuration of genes of animal and zoonotic human origin, indicating that genetic reassortment events generated these unusual human strains. Eight out of 11 genes (VP1, VP2, VP3, VP6, VP7, NSP3, NSP4 and NSP5) of the Italian G8P[14] strains exhibited close identity with a Spanish sheep strain, whereas the remaining genes (VP4, NSP1 and NSP2) were more closely related to human strains. The amino acid sequences of the antigenic regions of outer capsid proteins VP4 and VP7 were compared with vaccine and field strains, showing high conservation between the amino acid sequences of Apulia G8P[14] strains and human and animal strains bearing G8 and/or P[14] proteins, and revealing many substitutions with respect to the RotaTeq™ and Rotarix™ vaccine strains. Conversely, the amino acid analysis of the four antigenic sites of VP6 revealed a high degree of conservation between the two Apulia strains and the human and animal strains analyzed. These results reinforce the potential role of interspecies transmission and reassortment in generating novel rotavirus strains that might not be fully contrasted by current vaccines. PMID:27449953

    Mid-infrared shells or bubbles around expanding H II regions have received much attention due to their ability to initiate a new generation of star formation. We present multi-wavelength observations around two bubbles associated with a southern massive star-forming region G8.14+0.23, to investigate the triggered star formation signature on the edges of the bubbles by the expansion of the H II region. We have found observational signatures of the collected molecular and cold dust material along the bubbles and the {sup 12}CO(J = 3-2) velocity map reveals that the molecular gas in the bubbles is physically associated around the G8.14+0.23 region. We have detected 244 young stellar objects (YSOs) in the region and about 37% of these YSOs occur in clusters. Interestingly, these YSO clusters are associated with the collected material on the edges of the bubbles. We have found good agreement between the dynamical age of the H II region and the kinematical timescale of bubbles (from the {sup 12}CO(J = 3-2) line data) with the fragmentation time of the accumulated molecular materials to explain possible 'collect and collapse' process around the G8.14+0.23 region. However, one cannot entirely rule out the possibility of triggered star formation by compression of the pre-existing dense clumps by the shock wave. We have also found two massive embedded YSOs (about 10 and 22 M{sub Sun }) which are associated with the dense fragmented clump at the interface of the bubbles. We conclude that the expansion of the H II region is also leading to the formation of these two young massive embedded YSOs in the G8.14+0.23 region.

    Herpes simplex virus 1 (HSV-1) mRNAs are exported to the cytoplasm through the export receptor TAP/NFX1. HSV-1 multifunctional protein ICP27 interacts with TAP/NXF1, binds viral RNAs, and is required for efficient viral RNA export. In ICP27 mutant infections, viral RNA export is reduced but not ablated, indicating that other export adaptors can aid in viral RNA export. Export adaptor protein Aly/REF is recruited to viral replication compartments, however, Aly/REF knockdown has little effect on viral RNA export. SR proteins SRp20 and 9G8 interact with TAP/NXF1 and mediate export of some cellular RNAs. We report that siRNA knockdown of SRp20 or 9G8 resulted in about a 10 fold decrease in virus yields and in nuclear accumulation of polyA+ RNA. In infected cells depleted of SRp20, newly transcribed Bromouridine-labeled RNA also accumulated in the nucleus. We conclude that SRp20 and 9G8 contribute to HSV-1 RNA export. PMID:20227104

    A capability for measuring the thermal conductivity of microelectromechanical systems (MEMS) materials using a steady state resistance technique was developed and used to measure the thermal conductivities of SUMMiT{trademark} V layers. Thermal conductivities were measured over two temperature ranges: 100K to 350K and 293K to 575K in order to generate two data sets. The steady state resistance technique uses surface micromachined bridge structures fabricated using the standard SUMMiT fabrication process. Electrical resistance and resistivity data are reported for poly1-poly2 laminate, poly2, poly3, and poly4 polysilicon structural layers in the SUMMiT process from 83K to 575K. Thermal conductivity measurements for these polysilicon layers demonstrate for the first time that the thermal conductivity is a function of the particular SUMMiT layer. Also, the poly2 layer has a different variation in thermal conductivity as the temperature is decreased than the poly1-poly2 laminate, poly3, and poly4 layers.

  10. From the Earth Summit to Rio+20: integration of health and sustainable development.

    2012-06-01

    In 2012, world leaders will meet at the Rio+20 conference to advance sustainable development--20 years after the Earth Summit that resulted in agreement on important principles but insufficient action. Many of the development goals have not been achieved partly because social (including health), economic, and environmental priorities have not been addressed in an integrated manner. Adverse trends have been reported in many key environmental indicators that have worsened since the Earth Summit. Substantial economic growth has occurred in many regions but nevertheless has not benefited many populations of low income and those that have been marginalised, and has resulted in growing inequities. Variable progress in health has been made, and inequities are persistent. Improved health contributes to development and is underpinned by ecosystem stability and equitable economic progress. Implementation of policies that both improve health and promote sustainable development is urgently needed.

    Genetic variation at the ABCG5/G8 locus has been associated with markers of cholesterol homeostasis. As data originate from small-scale studies, we performed a meta-analysis to study these associations in a large dataset. We first investigated associations between five common ABCG5/G8 polymorphisms (p.Q604E, p.D19H, p.Y54C, p.T400K, and p.A632V) and plasma sterol levels in 245 hypercholesterolaemic individuals. No significant associations were found. Subsequently, our data were pooled into a meta-analysis that comprised 3,364 subjects from 16 studies (weighted mean age, 46.7 ± 10.5 years; BMI, 23.9 ± 3.5 kg/m2). Presence of the minor 632V allele correlated with reduced LDL-C concentrations (n = 367) compared with homozygosity for the 632A variant [n = 614; −0.11 mmol/l (95% CI, range: −0.20 to −0.02 mmol/l); P = 0.01]. The remaining polymorphisms were not associated with plasma lipid levels. Carriers of the 19H allele exhibited lower campesterol/TC (n = 83; P < 0.001), sitosterol/TC (P < 0.00001), and cholestanol/TC (P < 0.00001), and increased lathosterol/TC ratios (P = 0.001) compared with homozygous 19D allele carriers (n = 591). The ABCG8 632V variant was associated with a clinically irrelevant LDL-C reduction, whereas the 19H allele correlated with decreased cholesterol absorption and increased synthesis without affecting the lipid profile. Hence, associations between frequently studied missense ABCG5/G8 polymorphisms and markers of cholesterol homeostasis are modest at best. PMID:20581104

  12. Stimulation of murine biliary cholesterol secretion by thyroid hormone is dependent on a functional ABCG5/G8 complex

    Abstract Secretion of cholesterol into bile is important for the elimination of cholesterol from the body. Thyroid hormone (TH) increases biliary cholesterol secretion and hepatic gene expression of adenosine triphosphate (ATP)-binding cassette, subfamily G (WHITE), member 5 (ABCG5) and ATP-binding cassette, subfamily G (WHITE), member 8 (ABCG8), two half-transporters that act as a heterodimeric complex promoting sterol secretion. In addition, nuclear liver x receptor-alpha (LXRa), also regulated by TH, induces gene expression of ABCG5/G8. We here investigated if the TH-induced stimulation of biliary cholesterol secretion is mediated by the ABCG5/G8 complex in vivo, and if so, whether LXRa is involved. Mice homozygous for disruption of Abcg5 (Abcg5−/−) or Lxra (Lxra−/−) and their wild-type counterparts were treated with triiodothyronine (T3) for 14 days and compared to untreated mice of corresponding genetic backgrounds. Bile was collected by gallbladder cannulation, and liver samples were analyzed for gene expression levels. Basal biliary cholesterol secretion in Abcg5−/− mice was 72% lower than in Abcg5+/+ mice. T3 treatment increased cholesterol secretion 3.1-fold in Abcg5+/+ mice, whereas this response was severely blunted in Abcg5−/− mice. In contrast, biliary cholesterol secretion in T3-treated Lxra+/+ and Lxra−/− mice was increased 3.5- and 2.6-fold, respectively, and did not differ significantly. Conclusions: TH-induced secretion of cholesterol into bile is largely dependent on an intact ABCG5/G8 transporter complex, whereas LXRa is not critical for this effect.

  13. Deletion of Huntington's disease-linked G8 (D4S10) locus in Wolf-Hirschhorn syndrome.

    Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder characterized by progressive involuntary movements and dementia. The symptoms of the disease, although devastating in severity, do not usually appear until the third to fourth decade of life. The gene defect is highly penetrant, and results in the loss of neurones in the basal ganglia, globus pallidus, and more diffusely in the cortex. A DNA marker, G8 (or D4S10), is tightly linked to Huntington's disease and this gene has been localized to chromosome 4 (ref. 3). The discovery of this linkage marker raises the possibility of developing a presymptomatic test for the disorder, and of eventually isolating the disease gene based on its map position. We have now regionally localized the DNA marker G8 to the terminal band of the short arm of the chromosome, a region representing approximately 0.5% of the total human genome. The assignment was made by examining DNA from patients with Wolf-Hirschhorn syndrome, a birth defect resulting from partial heterozygous deletion of the short arm of chromosome 4.

    The Emory University Center for Public Health Preparedness held two summits for nurses that were evaluated by survey. Participants cited multiple deficiencies and challenges with integrating emergency preparedness into nursing curricula. The summits and the related materials were reported as highly useful by survey respondents. More than three fourths of respondents reported incorporating emergency preparedness education into their curricula after summit attendance. Nursing professionals could use summits to encourage active practitioners to pursue continuing education and to initiate efforts to incorporate emergency preparedness and related health care issues into the curricula of schools of nursing.

  17. Summit geomorphology of western Pacific guyots

    NASA Astrophysics Data System (ADS)

    Van Waasbergen, Robert J.; Winterer, Edward L.

    Bathymetric and seismic reflection data for 21 guyots in the Japanese, Wake and Mid Pacific Mountains seamount groups show that many guyots bear thick shallow-water limestone deposits that represent nearly undeformed Cretaceous rudist-reef-bounded carbonate platforms. Three types of guyot summits are distinguished: those with more than 200 m of shallow-water limestone, sufficient to bury the underlying volcanic relief, follow the same basic morphologic patterns as their coral/algal-dominated modern counterparts. Surface morphology is controlled by the original reef/platform configuration, modified by subaerial erosion and by long-term deformation of the sedimentary deposits and the underlying volcanic edifice. These seamounts range in age from Barremian to Aptian, with Barremian or Aptian to late Albian limestone deposits. Guyots with thin limestone deposits represent reef-bearing volcanic islands at various stages of fringing-reef and barrier-reef development. These edifices and their overlying limestone deposits are of Albian age. Reef growth on these was suddenly halted when regional emergence led to cessation of shallow-water-limestone accumulation on all guyots in the western Pacific, probably during the latest Albian. The karstic surfaces were resubmerged by middle Turonian time and, in latitudes south of about 20°N, blanketed by pelagic ooze. Guyots without reef deposits appear to be products of post-Albian volcanism and erosion at sea level. Among the three types of summit-configurations a range of stages of development of Cretaceous carbonate-platforms can be observed. The exposure of the guyot summits indicated by the occurence of karstic relief of 100-200 m on many of the limestone caps suggests that the sea floor of the western Pacific was raised several hundred meters. The age and platform thickness-relationships among the different types of guyots suggests that this uplift occurred at late Albian time.

  2. The social summit: a gender perspective.

    PubMed

    1995-01-01

    This editorial introduction to an issue of INSTRAW News notes that the UN has undertaken a year long series of important international conferences, starting with the September 1994 Conference on Population and Development. The second major conference is the World Summit for Social Development, and the third is the Fourth World Conference on Women. At these conferences, the international community is coming together to rescue the people whose lives have been threatened by the legacy of the Cold War: ethnic, religious, and cultural violence and exacerbation of the gap between rich and poor. Women are an integral part of the developing social agenda because women are a magnifying glass, rather than simply a mirror, of the problems of society. This issue of INSTRAW News provides a broad overview of how gender issues have evolved and the changes which occurred as a result. Specific gender issues are analyzed as they impact the three core items of the Social Summit agenda: attacking poverty, creating jobs, and building social solidarity. PMID:12157783

    Background Organochlorine pesticides (OCPs) are one kind of persistent organic pollutants. Although they are reported to be associated with metabolic disorders, the underlying mechanism is unclear. We explored the association of OCPs with gallstone disease and its influence on hepatic lipid metabolism. Materials and Methods OCPs levels in omentum adipose tissues from patients with and without gallstone disease between 2008 and 2011 were measured by GC-MS. Differences of gene expression involved in hepatic lipid metabolism and hepatic lipids content were compared in liver biopsies between groups with high and low level of OCPs. Using HepG2 cell lines, the influence on hepatic lipid metabolism by individual OCP was evaluated in vitro. Results In all patients who were from non-occupational population, there were high levels of β-hexachlorocyclohexane (β-HCH) and p',p'-dichloroethylene (p',p'-DDE) accumulated in adipose tissues. Both β-HCH and p', p'-DDE levels were significantly higher in adipose tissues from patients with gallstone disease (294.3± 313.5 and 2222± 2279 ng/g of lipid) than gallstone-free controls (282.7± 449.0 and 2025±2664 ng/g of lipid, P< 0.01) and they were strongly related with gallstone disease (P for trend = 0.0004 and 0.0138). Furthermore, higher OCPs in adipose tissue led to increase in the expression of hepatic cholesterol transporters ABCG5 and G8 (+34% and +27%, P< 0.01) and higher cholesterol saturation index in gallbladder bile, and induced hepatic fatty acids synthesis, which was further confirmed in HepG2 cells. Conclusion OCPs might enhance hepatic secretion of cholesterol into bile via ABCG5/G8 which promoting gallstone disease as well as lipogenesis. PMID:27203212

    Students simulated the 2011 Durban Climate Summit in order to experience two roles: global diplomats attempting to solve a significant global problem and scientists as contributors of knowledge. Together, they worked to develop a framework to provide global solutions as world leaders. This project demonstrated [highlighted?] student work from the climate summit, describing how students promoted dialogue and provided climate science information to their diplomatic peers, who then used this information in diplomatic negotiations. By focusing on increasing student climate literacy, students engaged in both climate science and global diplomacy through meaningful simulations to understand the global and political issues surrounding Climate Change mitigation. Three classes of international middle school students attending Johns Hopkins Center for Talented Youth summer programs enacted the 2011 Durban Model United Nations meeting. One class developed a deep understanding of climate and climate science by working with computer models and data to represent members of the IPCC. Members of this class collaborated with climate scientists, conducted experiments, and developed a well-rounded understanding of paleoclimate, current climatic trends, carbon cycling, and modeling future outcomes. Two additional classes took on the roles of UN diplomats, researched their respective nations, engaged in practice UN simulations, and developed a working understanding of the diplomatic process. Students representing the IPCC assisted their diplomatic peers in developing and proposing possible UN resolutions. All three classes worked together to enact the Durban Climate Summit with the underlying focus of developing diplomatic Climate Change mitigation strategies and ultimately resolutions for member nations.

  6. The Education Summit; A Different Signal

    The last National Education Summit held by the Governors occurred in Charlottesville, Virginia in 1989. That Summit, chaired by then Governor Clinton, produced the national goals for education announced by President Bush. These top-down goals are unfulfilled and are, for all practical purposes, dead. The 1996 Education Summit seems different, although its recommendations may suffer the same fate of those of the 1989 Summit. The 1996 Education Summit was held at IBM's Executive Conference Center in Palisades, New York. The Governors invited 44 executives of major businesses from virtually every state. CEO's from IBM, AT&T, Bell South, Eastman Kodak, Procter & Gamble, and Boeing were a part of the planning committee. Absent, for the most part, were professional educators and their organizations. The constitution of the 1996 Education Summit sent a clear signal, viz., that the "professional educators," whatever their individual talents, as a group have failed the nation's public schools and now its time for someone else to try. The "someone else" is the group of individuals that are the ultimate consumers of the output of the American education system. The collective point of view of the attending CEO's is that companies have undergone radical changes to become globally competitive, now it's time to keep the work force equally competitive. And this can only come through radical changes in the educational system. The CEO's point out that the companies they represent live or die by the (international) standards they establish, some of which are expressed in the principles of Total Quality Management (TQM), which represents a systemic approach to the changes American industry had to undergo to stay competitive. The executives clearly have run out of patience with the current system of public education. Many feel that they are running out of talented people to fill the important jobs that this society will need to fill to keep it moving forward. That talent is not being

    Tuberculosis (TB) poses a grave predicament to the world as it is not merely a scientific challenge but a socio-economic burden as well. A prime cause of mortality in human due to an infectious disease; the malady and its cause, Mycobacterium tuberculosis have remained an enigma with many questions that remain unanswered. The ability of the pathogen to survive and switch between varied physiological states necessitates a protracted therapeutic regimen that exerts an excessive strain on low-resource countries. To complicate things further, there has been a significant rise of antimicrobial resistance. Existing control measures, including treatment regimens have remained fairly uniform globally for at least half a century and require reinvention. Overcoming the societal and scientific challenges requires an increase in dialog to identify key regions that need attention and effective partners with whom successful collaborations can be fostered. In this report, we explore the discussions held at the International TB Summit 2015 hosted by EuroSciCon, which served as an excellent platform for researchers to share their recent findings. Ground-breaking results require outreach to affect policy design, governance and control of the disease. Hence, we feel it is important that meetings such as these reach a wider, global audience.

    Background The association of ATP-binding cassette (ABC) transporter single nucleotide polymorphisms (SNPs) and serum lipid profiles is inconsistent. The present study was undertaken to detect the association of ABCG5/G8 SNPs and several environmental factors with serum lipid levels. Methodology/Principal Findings Genotyping of the ABCG5 (rs4131229 and rs6720173) and ABCG8 (rs3806471 and rs4148211) SNPs was performed in 719 unrelated subjects of Mulao nationality and 782 participants of Han nationality. There were no differences in the genotypic and allelic frequencies of four SNPs between the two ethnic groups besides the genotypic frequencies of rs4131229 SNP in Han. The levels of triglyceride (TG), apolipoprotein (Apo) A1, and ApoA1/ApoB ratio (rs4131229); low-density lipoprotein cholesterol (LDL-C) and ApoB (rs6720173); high-density lipoprotein cholesterol (HDL-C), ApoA1, ApoB, and ApoA1/ApoB ratio (rs3806471); and HDL-C, ApoA1, and ApoA1/ApoB ratio (rs4148211) in Han were different among their genotypes (P<0.05–0.001). The levels of LDL-C (rs6720173) and ApoA1 (rs3806471) in Mulao were also different among their genotypes (P<0.05 for each). The levels of TC, TG, HDL-C, ApoA1, and ApoA1/ApoB ratio (rs4131229); LDL-C and ApoB (rs6720173); HDL-C, ApoA1, and ApoA1/ApoB ratio (rs3806471); and TG, HDL-C, ApoA1, and ApoA1/ApoB ratio (rs4148211) in Han males; and ApoA1/ApoB ratio (rs4131229); LDL-C, ApoB, and ApoA1/ApoB ratio (rs3806471); HDL-C, ApoA1, and ApoA1/ApoB ratio (rs4148211) in Han females were different between the genotypes (P<0.05–0.001). The levels of LDL-C in Mulao females were also different between GG and GC/CC genotypes of rs6720173 (P<0.05). The correlation between serum lipid parameters and genotypes of four SNPs was observed in Han, especially in Han males. Serum lipid parameters were also correlated with several environmental factors.

The rover took the images on Martian days, or sols, 672 to 677 (Nov. 23 to 28, 2005 -- the Thanksgiving holiday weekend).

    This image is an approximately true-color rendering using camera's 750-, 530-, and 430-nanometer filters. Seams between individual frames have been eliminated from the sky portion of the mosaic to better simulate the vista a person standing on Mars would see.

    'Home Plate,' a bright, semi-circular feature scientists hope to investigate, is harder to discern in this image than in earlier views taken from higher up the hill. Spirit acquired this more oblique view, known as the 'Seminole panorama,' from about halfway down the south flank of Husband Hill, 50 meters (164 feet) or so below the summit. Near the center of the panorama, on the horizon, are 'McCool Hill' and 'Ramon Hill,' named, like Husband Hill, in honor of the fallen astronauts of the space shuttle Columbia. Husband Hill is visible behind the rover, on the right and left sides of the panorama. An arc of rover tracks made while avoiding obstacles and getting into position to examine rock outcrops can be traced over a long distance by zooming in to explore the panorama in greater detail.

    Spirit is now significantly farther downhill toward the center of this panorama, en route to Home Plate and other enigmatic soils and outcrop rocks in the quest to uncover the history of Gusev Crater and the 'Columbia Hills.'

  16. The Education Summit; A Different Signal

    The last National Education Summit held by the Governors occurred in Charlottesville, Virginia in 1989. That Summit, chaired by then Governor Clinton, produced the national goals for education announced by President Bush. These top-down goals are unfulfilled and are, for all practical purposes, dead. The 1996 Education Summit seems different, although its recommendations may suffer the same fate of those of the 1989 Summit. The 1996 Education Summit was held at IBM's Executive Conference Center in Palisades, New York. The Governors invited 44 executives of major businesses from virtually every state. CEO's from IBM, AT&T, Bell South, Eastman Kodak, Procter & Gamble, and Boeing were a part of the planning committee. Absent, for the most part, were professional educators and their organizations. The constitution of the 1996 Education Summit sent a clear signal, viz., that the "professional educators," whatever their individual talents, as a group have failed the nation's public schools and now its time for someone else to try. The "someone else" is the group of individuals that are the ultimate consumers of the output of the American education system. The collective point of view of the attending CEO's is that companies have undergone radical changes to become globally competitive, now it's time to keep the work force equally competitive. And this can only come through radical changes in the educational system. The CEO's point out that the companies they represent live or die by the (international) standards they establish, some of which are expressed in the principles of Total Quality Management (TQM), which represents a systemic approach to the changes American industry had to undergo to stay competitive. The executives clearly have run out of patience with the current system of public education. Many feel that they are running out of talented people to fill the important jobs that this society will need to fill to keep it moving forward. That talent is not being

    Here, we describe the methodologies adopted to ensure that natural seawater, used as "influent water" for the land test, complies with the requirement that should be fulfilled to show the efficacy of the new ballast water treatment system (BWTS). The new BWTS was located on the coast of SW Sicily (Italy), and the sampled seawater showed that bacteria and plankton were two orders of magnitude lower than requested. Integrated approaches for preparation of massive cultures of bacteria (Alcanivorax borkumensis and Marinobacter hydrocarbonoclasticus), algae (Tetraselmis suecica), rotifers (Brachionus plicatilis), and crustaceans (Artemia salina) suitable to ensure that 200 m(3) of water fulfilled the international guidelines of MEPC.174(58)G8 are here described. These methodologies allowed us to prepare the "influent water" in good agreement with guidelines and without specific problems arising from natural conditions (seasons, weather, etc.) which significantly affect the concentrations of organisms at sea. This approach also offered the chance to reliably run land tests once every two weeks. PMID:26403705

  2. Summit Lake landslide and geomorphic history of Summit Lake basin, northwestern Nevada

    1990-01-01

    The Summit Lake landslide, northwestern Nevada, composed of Early Miocene pyroclastic debris, Ashdown Tuff, and basalt and rhyolite of the Black Rock Range, blocked the upper Soldier Creek-Snow Creek drainage and impounded Summit Lake sometimes prior to 7840 yr B.P. The slide covers 8.2 km2 and has geomorphic features characteristic of long run-out landslides, such as lobate form, longitudinal and transverse ridges, low surface gradient (7.1 ??), and preservation of original stratigraphic position of transported blocks. However, estimated debris volume is the smallest reported (2.5 ?? 105 m3) for a landslide of this type. The outflow channel of the Summit Lake basin was a northward-flowing stream valley entrenched by Mahogany Creek. Subsequent negative tectonic adjustment of the basin by about 35 m, accompanied by concommitant progradation of a prominent alluvial fan deposited by Mahogany Creek, argues for a probable diversion of drainage from the Alvord basin southward into the Lahontan basin. The landslide occurred while the creek flowed southward, transferring about 147 km2 of watershed from the Lahontan basin back to the Alvord basin. Overflow northward occurred during high stands of Pluvial Lake Parman in the basin; otherwise, under drier climates, the Summit Lake basin has been closed. Within large depressions on the slide surface, the ca. 6800 yr old Mazama Bed and other sediments have buried a weakly developed soil. Disseminated humus in the soil yields an age of 7840 ?? 310 yr B.P. Absence of older tephra (such as St. Helens M) brackets the slide age between 7840 and 19,000 yr B.P. Projectile points found on the highest strandlines of Pluvial Lake Parman suggest a ca 8700 yr B.P. age by correlation with cultural artifacts and radiocarbon ages from nearby Last Supper Cave, Nevada. Organic matter accumulation in landslide soils suggests ages ranging from 9100 to 16,250 yr B.P. Estimation of the age of the slide from morphologic data for the isolated Summit

    We report the genomic characterization of a rare human G8P[14] rotavirus strain, identified in a stool sample from Guatemala (GTM) during routine rotavirus surveillance. This strain was designated as RVA/Human-wt/GTM/2009726790/2009/G8P[14], with a genomic constellation of G8-P[14]-I2-R2-C2-M2-A13-N2-T6-E2-H3. The VP4 gene occupied lineage VII within the P[14] genotype. Phylogenetic analysis of each genome segment revealed close relatedness to several zoonotic simian, guanaco and bovine strains. Our findings suggest that strain RVA/Human-wt/GTM/2009726790/2009/G8P[14] is an example of a direct zoonotic transmission event. The results of this study reinforce the potential role of interspecies transmission and reassortment in generating novel and rare rotavirus strains which infect humans.

    The metabolic fate of newly absorbed cholesterol and phytosterol is orchestrated through adenosine triphosphate-binding cassette transporter G5 and G8 heterodimer (G5G8), and acyl CoA:cholesterol acyltransferase 2 (ACAT2). We hypothesized that intestinal G5G8 limits sterol absorption by reducing substrate availability for ACAT2 esterification and have attempted to define the roles of these two factors using gene deletion studies in mice. Male ACAT2−/−, G5G8−/−, ACAT2−/−G5G8−/− (DKO), and wild-type (WT) control mice were fed a diet with 20% of energy as palm oil and 0.2% (w/w) cholesterol. Sterol absorption efficiency was directly measured by monitoring the appearance of [3H]sitosterol and [14C]cholesterol tracers in lymph after thoracic lymph duct cannulation. The average percentage (± SEM) absorption of [14C]cholesterol after 8 h of lymph collection was 40.55 ± 0.76%, 19.41 ± 1.52%, 32.13 ± 1.60%, and 21.27 ± 1.35% for WT, ACAT2−/−, G5G8−/−, and DKO mice, respectively. [3H]sitosterol absorption was <2% in WT and ACAT2−/− mice, whereas it was up to 6.8% in G5G8−/− and DKO mice. G5G8−/− mice also produced chylomicrons with ∼70% less cholesterol ester mass than WT mice. In contrast to expectations, the data demonstrated that the absence of G5G8 led to decreased intestinal cholesterol esterification and reduced cholesterol transport efficiency. Intestinal G5G8 appeared to limit the absorption of phytosterols; ACAT2 more efficiently esterified cholesterol than phytosterols. The data indicate that handling of sterols by the intestine involves both G5G8 and ACAT2 but that an additional factor (possibly Niemann-Pick C1-like 1) may be key in determining absorption efficiency.

  12. Unexpected Melt at Summit, Greenland: Its Potential Legacy

    NASA Astrophysics Data System (ADS)

    2012-12-01

    Summit, Greenland is a high altitude cold site where snow on the ice sheet rarely melts; it was the site where the GISP2 ice core was drilled almost two decades ago. In July 2012, unusual meteorological events caused the surface snow at Summit to experience a very rare true melt event. The melt period was short-lived, and subfreezing temperatures soon turned the melt into an ice layer. Modern satellite-born sensing technologies provided the first opportunity to witness and confirm that indeed the melt was very widespread over most of the surface of the Greenland Ice Sheet. Many tens of meters beneath the firn surface at Summit is the next significantly thick ice layer, dating to 1889; this layer also has been identified at a number of other sites in Greenland. The 2012 melt at Summit provided an unusual opportunity to investigate the way in which the melt alters the properties of the snow at this site. Measurements of the nature of the melt at Summit in 2012 and its impact on stratigraphy, density, permeability, and grain size are presented. Insights from the observations we made in July 2012 and comparisons with characteristics of the 1889 ice layer from Summit are employed in a description of the potential impacts of refrozen melt layers on polar snow and firn processes in the dry snow zones of ice sheets. The potential legacy that the 2012 ice layer may imprint on future ice core records is discussed.

  13. IS PROTOSTELLAR HEATING SUFFICIENT TO HALT FRAGMENTATION? A CASE STUDY OF THE MASSIVE PROTOCLUSTER G8.68-0.37

    If star formation proceeds by thermal fragmentation and the subsequent gravitational collapse of the individual fragments, how is it possible to form fragments massive enough for O and B stars in a typical star-forming molecular cloud where the Jeans mass is about 1 M{sub sun} at the typical densities (10{sup 4} cm{sup -3}) and temperatures (10 K)? We test the hypothesis that a first generation of low-mass stars may heat the gas enough that subsequent thermal fragmentation results in fragments {>=}10 M{sub sun}, sufficient to form B stars. We combine ATCA and Submillimeter Array observations of the massive star-forming region G8.68-0.37 with radiative transfer modeling to derive the present-day conditions in the region and use this to infer the conditions in the past, at the time of core formation. Assuming that the current mass/separation of the observed cores equals the fragmentation Jeans mass/length and the region's average density has not changed requires the gas temperature to have been 100 K at the time of fragmentation. The postulated first generation of low-mass stars would still be around today, but the number required to heat the cloud exceeds the limits imposed by the observations. Several lines of evidence suggest the observed cores in the region should eventually form O stars yet none have sufficient raw material. Even if feedback may have suppressed fragmentation, it was not sufficient to halt it to this extent. To develop into O stars, the cores must obtain additional mass from outside their observationally defined boundaries. The observations suggest that they are currently fed via infall from the very massive reservoir ({approx}1500 M{sub sun}) of gas in the larger parsec scale cloud around the star-forming cores. This suggests that massive stars do not form in the collapse of individual massive fragments, but rather in smaller fragments that themselves continue to gain mass by accretion from larger scales.

    Outcomes of the World Humanitarian Summit were mixed with some refreshing new directions being endorsed and a lack of systemic reform. The selective agenda and OCHAs lack of success in engaging pre-meeting political participation not only hampered the Summit's ability to deal with global issues and institutional reform, but also alienated it from leading aid agencies and governments. The UN's failure to commit to humanitarian principles and global disarray of the humanitarian system indicates the need for extensive reform or a new global humanitarian body. This agency needs to employ a decentralized model to manage aid funds, assume coordination of international responses, resolve civil-military coordination, cater for people affected by both conflict and disasters, and professionalize the humanitarian career.

    The splicing regulatory SR protein, 9G8, has recently been proposed to function in mRNA export in conjunction with the export protein, Tap/NXF1. Tap interacts directly with the Mason-Pfizer monkey virus constitutive transport element (CTE), an element that enables export of unspliced, intron-containing mRNA. Based on our previous finding that Tap can promote polysome association and translation of CTE-RNA, we investigated the effect of 9G8 on cytoplasmic RNA fate. 9G8 was shown to enhance expression of unspliced RNA containing either the Mason-Pfizer monkey virus-CTE or the recently discovered Tap-CTE. 9G8 also enhanced polyribosome association of unspliced RNA containing a CTE. Hyperphosphorylated 9G8 was present in monosomes and small polyribosomes, whereas soluble fractions contained only hypophosphorylated protein. Our results are consistent with a model in which hypophosphorylated SR proteins remain stably associated with messenger ribonucleoprotein (mRNP) complexes during export and are released during translation initiation concomitant with increased phosphorylation. These results provide further evidence for crucial links between RNA splicing, export and translation. PMID:17513303

    High above the world-class observatories that dot Hawaii's dormant Mauna Kea volcano, floating farther yet over the hostile and nearly inaccessible peaks of Mt. Everest, lies a summit waiting to be conquered. Here above the clouds and city lights and over 99.7% of the atmosphere is a platform on the edge of space, home to a broad range of astronomy and physics experiments. Today, balloons are lifting experiments longer, higher and more inexpensively than ever before, and returning them safely to Earth for reuse. Week-long flights at altitudes of approximately 35 kilometers carrying payloads in excess of several tons are the norm. NASA now plans to extend this platform and create a new generation of balloons capable of staying afloat with such cargo for 100 days and ultimately 1,000 days. What do some scientists hope to accomplish with 100 or even 1,000 days at the edge of space? To name but a few proposals on the table: Jupiter-size planet searches, large-aperture solar astronomy, large-aperture infrared astronomy, cosmic-ray investigations, long-duration Earth science missions, and hard x-ray imaging experiments. Olympus defines a new era in scientific ballooning. Advances in material science and trajectory control are enabling revolutionary capabilities. Very large scientific payloads can now be reliably launched and retrieved for reflight at a range of altitudes. Balloon flight still remains a fraction of the cost of a rocket launch. The ultra long duration balloon, with its 100-day maiden flight planned for 2001, provides a long-term facility in a near-space environment for many types of science. This is a stratospheric mountaintop well worth the climb.

    The Mushroom Council convened the Mushrooms and Health Summit in Washington, DC, on 9–10 September 2013. The proceedings are synthesized in this article. Although mushrooms have long been regarded as health-promoting foods, research specific to their role in a healthful diet and in health promotion has advanced in the past decade. The earliest mushroom cultivation was documented in China, which remains among the top global mushroom producers, along with the United States, Italy, The Netherlands, and Poland. Although considered a vegetable in dietary advice, mushrooms are fungi, set apart by vitamin B-12 in very low quantity but in the same form found in meat, ergosterol converted with UV light to vitamin D2, and conjugated linoleic acid. Mushrooms are a rare source of ergothioneine as well as selenium, fiber, and several other vitamins and minerals. Some preclinical and clinical studies suggest impacts of mushrooms on cognition, weight management, oral health, and cancer risk. Preliminary evidence suggests that mushrooms may support healthy immune and inflammatory responses through interaction with the gut microbiota, enhancing development of adaptive immunity, and improved immune cell functionality. In addition to imparting direct nutritional and health benefits, analysis of U.S. food intake survey data reveals that mushrooms are associated with higher dietary quality. Also, early sensory research suggests that mushrooms blended with meats and lower sodium dishes are well liked and may help to reduce intakes of red meat and salt without compromising taste. As research progresses on the specific health effects of mushrooms, there is a need for effective communication efforts to leverage mushrooms to improve overall dietary quality. PMID:24812070

    To address lagging vaccine coverage among adults in the United States, over 150 organizations representing a wide range of immunization partners convened in Atlanta, GA from May 15-16, 2012 for the inaugural National Adult Immunization Summit. The meeting called for solution-oriented discussion toward improving current immunization levels, implementing the 2011 National Vaccine Advisory Committee adult immunization recommendations, and capitalizing on new opportunities to improve coverage. Provisions in the federal health reform law that increase access to preventive services, including immunizations, and the increasing numbers of complementary vaccine providers such as pharmacists, create new opportunities to increase access for immunization services and improve coverage for adults. The Summit organized around five focal areas: empowering providers, quality and performance measures, increasing access and collaboration, educating patients, and informing decision-makers. These focal areas formed the basis of working groups, charged to coordinate efforts by the participating organizations to address gaps in the current immunization system. Summit participants identified priority themes to address as tasks during the coming year, including better communicating the value of immunizations to increase demand for immunizations, creating a central repository of resources for providers, patients, and others interested in improving adult immunization levels, examining performance and quality measures and evaluating means to use such measures to motivate vaccine providers, increasing engagement with employer and employee groups to increase awareness and demand for vaccinations, improving the use of immunization information systems and electronic health reports, decreasing barriers to all vaccine providers including pharmacists and community vaccinators, decreasing the complexity of the adult vaccine schedule where possible, engaging adult immunization champions and leaders in

    To address lagging vaccine coverage among adults in the United States, over 150 organizations representing a wide range of immunization partners convened in Atlanta, GA from May 15-16, 2012 for the inaugural National Adult Immunization Summit. The meeting called for solution-oriented discussion toward improving current immunization levels, implementing the 2011 National Vaccine Advisory Committee adult immunization recommendations, and capitalizing on new opportunities to improve coverage. Provisions in the federal health reform law that increase access to preventive services, including immunizations, and the increasing numbers of complementary vaccine providers such as pharmacists, create new opportunities to increase access for immunization services and improve coverage for adults. The Summit organized around five focal areas: empowering providers, quality and performance measures, increasing access and collaboration, educating patients, and informing decision-makers. These focal areas formed the basis of working groups, charged to coordinate efforts by the participating organizations to address gaps in the current immunization system. Summit participants identified priority themes to address as tasks during the coming year, including better communicating the value of immunizations to increase demand for immunizations, creating a central repository of resources for providers, patients, and others interested in improving adult immunization levels, examining performance and quality measures and evaluating means to use such measures to motivate vaccine providers, increasing engagement with employer and employee groups to increase awareness and demand for vaccinations, improving the use of immunization information systems and electronic health reports, decreasing barriers to all vaccine providers including pharmacists and community vaccinators, decreasing the complexity of the adult vaccine schedule where possible, engaging adult immunization champions and leaders in

    Group A rotavirus is a major cause of severe gastroenteritis in children and young animals. During a retrospective analysis of samples collected from Paraguayan children under 5 years old with diarrhea, and previously negative for rotavirus and norovirus, we detected the presence of bovine rotavirus sequences by viral metagenomics. Nucleic acid was extracted direct from stool sample and determined to be G8P[1]. The genomic analyzes revealed that the strain presents an Artiodactyl-like genome (G8-P[1]-I2-R2-C2-M1-Ax-N2-T6-E12-H3) suggesting a direct animal-to-human transmission.

    The RASCALS (Radiation, Snow Characteristics and Albedo at Summit) campaign [1] was carried out at the Greenland Summit camp research station during June - July 2010. The collection of surface roughness, dielectric constant and density profiles of snow were carried out concurrently with snow albedo and bidirectional reflectance distribution function (BRDF) measurements. Polarimetric interferometry of Radarsat-2 quad pol fine beam images is used to study the snow surface anisotropy at Summit, Greenland. Various methods of determining the polarimetric coherence are tested and the results are compared with the in situ surface roughness results, which show a clear anisotropy varying with time. In addition, surface backscattering modelling is used to check the fraction of the surface backscattering.

    The orientations and ages of elongate summit calderas on major polygenetic volcanoes were compiled to document Miocene to Pleistocene Sh (minimum horizontal stress) directions on the western and northern flanks of the West Antarctic rift system. Miocene to Pleistocene summit calderas along the western Ross Sea show relatively consistent ENE long axis trends, which are at a high angle to the Transantarctic Mountain Front and parallel to the N77ºE Sh direction at Cape Roberts. The elongation directions of many Miocene to Pleistocene summit calderas in Marie Byrd Land parallel the alignment of polygenetic volcanoes in which they occur, except several Pleistocene calderas with consistent NNE to NE trends. The overall pattern of elongate calderas in Marie Byrd Land is probably due to a combination of structurally controlled orientations and regional stress fields in which Sh is oriented NNE to NE at a moderate to high angle to the trace of the West Antarctic rift system.

    at Summit, Greenland suggest that the annual mean near-surface air temperature increased at 0.09 ± 0.01°C/a over the 1982-2011 climatology period. This rate of warming, six times the global average, places Summit in the 99th percentile of all globally observed warming trends over this period. The rate of warming at Summit is increasing over time. During the instrumental period (1987-2011), warming has been greatest in the winter season, although the implications of summer warming are more acute. The annual maximum elevation of the equilibrium line and dry snow line has risen at 44 and 35 m/a over the past 15 and 18 years, respectively. Extrapolation of this observed trend now suggests, with 95% confidence intervals, that the dry snow facies of the Greenland Ice Sheet will inevitably transition to percolation facies. There is a 50% probability of this transition occurring by 2025.

  7. The World Summit for Social Development.

    PubMed

    1995-01-01

    The three goals of the UN World Summit for Social Development are to attack poverty, build solidarity, and create jobs. Unprecedented population growth has led to recognition of the need for a new, people-centered vision of development to counter the mutually reinforcing threats posed to world stability by poverty, unemployment, and social disintegration. This population growth may result in an inability of humanity to adapt and create unrelenting pressure on the world's natural resources. It has become increasingly recognized that improvements in the status of women will be vital to ensuring the future of humanity. Giving women the ability to decide their family size will eliminate hundreds of thousands of maternal deaths each year and will slow population growth while it increases women's productivity and control over resources. As the industrialized nations engage in unsustainable patterns of production and consumption, the lowest-income countries are caught in a "poverty-population-environment spiral." Although population growth is gradually slowing, the population of the world could double by 2050, with 95% of the growth occurring in developing countries. Concern is also mounting over the increasing urbanization of the world as well as the fact that while the populations of poor countries are becoming larger and younger, the population of industrialized countries are becoming older and smaller. The new vision of sustainable development involves generating economic growth, distributing benefits equitably, and allowing the regeneration of the environment. Without such security, the world can not achieve peace. The symptoms of social discrimination include social exclusion, which affects 90% of the world's population; sex and racial discrimination, which lowers the quality of life and increases life-threatening risks for women, indigenous people, and Blacks; violence and abuse, reflected in fact that the US has the highest incidence of murder in the world, in the

    2003-01-01

    This report consists of a large map sheet and a pamphlet. The map shows the geology, some photographs, description of map units, and correlation of map units. The pamphlet gives the full text about the geologic map. The area covered by this map includes parts of four U.S. Geological Survey 7.5' topographic quadrangles (Kilauea Crater, Volcano, Ka`u Desert, and Makaopuhi). It encompasses the summit, upper rift zones, and Koa`e Fault System of Kilauea Volcano and a part of the adjacent, southeast flank of Mauna Loa Volcano. The map is dominated by products of eruptions from Kilauea Volcano, the southernmost of the five volcanoes on the Island of Hawai`i and one of the world's most active volcanoes. At its summit (1,243 m) is Kilauea Crater, a 3 km-by-5 km collapse caldera that formed, possibly over several centuries, between about 200 and 500 years ago. Radiating away from the summit caldera are two linear zones of intrusion and eruption, the east and the southwest rift zones. Repeated subaerial eruptions from the summit and rift zones have built a gently sloping, elongate shield volcano covering approximately 1,500 km2. Much of the volcano lies under water; the east rift zone extends 110 km from the summit to a depth of more than 5,000 m below sea level; whereas the southwest rift zone has a more limited submarine continuation. South of the summit caldera, mostly north-facing normal faults and open fractures of the Koa`e Fault System extend between the two rift zones. The Koa`e Fault System is interpreted as a tear-away structure that accommodates southward movement of Kilauea's flank in response to distension of the volcano perpendicular to the rift zones.

    An inverse relationship exists between the summit deflation of Kilauea, as recorded by summit tilt, and the elevation of associated eruptive vents on the East Rift Zone. This relationship implies that East Rift eruptions drain the summit magma reservior to pressure levels that are dependent on the elevation of the eruptive vents.

  13. Compliant membranes for the development of MEMS dual-backplate capacitive microphone using the SUMMiT V fabrication process.

    2005-11-01

    The objective of this project is the investigation of compliant membranes for the development of a MicroElectrical Mechanical Systems (MEMS) microphone using the Sandia Ultraplanar, Multilevel MEMS Technology (SUMMiT V) fabrication process. The microphone is a dual-backplate capacitive microphone utilizing electrostatic force feedback. The microphone consists of a diaphragm and two porous backplates, one on either side of the diaphragm. This forms a capacitor between the diaphragm and each backplate. As the incident pressure deflects the diaphragm, the value of each capacitor will change, thus resulting in an electrical output. Feedback may be used in this device by applying a voltage between the diaphragm and the backplates to balance the incident pressure keeping the diaphragm stationary. The SUMMiT V fabrication process is unique in that it can meet the fabrication requirements of this project. All five layers of polysilicon are used in the fabrication of this device. The SUMMiT V process has been optimized to provide low-stress mechanical layers that are ideal for the construction of the microphone's diaphragm. The use of chemical mechanical polishing in the SUMMiT V process results in extremely flat structural layers and uniform spacing between the layers, both of which are critical to the successful fabrication of the MEMS microphone. The MEMS capacitive microphone was fabricated at Sandia National Laboratories and post-processed, packaged, and tested at the University of Florida. The microphone demonstrates a flat frequency response, a linear response up to the designed limit, and a sensitivity that is close to the designed value. Future work will focus on characterization of additional devices, extending the frequency response measurements, and investigating the use of other types of interface circuitry.

  5. Opsonin-independent ligation of Fc gamma receptors. The 3G8-bearing receptors on neutrophils mediate the phagocytosis of concanavalin A- treated erythrocytes and nonopsonized Escherichia coli

    PubMed Central

    1987-01-01

    We report that phagocytosis by human neutrophils of Con A-treated erythrocytes (E-Con A) and nonopsonized Escherichia coli with mannose- binding adhesions is mediated by the Fc gamma receptor bearing the 3G8 epitope. Modulation of Fc receptors by pretreating with aggregated-IgG or with 3G8 anti-Fc gamma receptor mAb markedly inhibited internalization of E-Con A and E. coli without altering their cell surface attachment. Phagocytosis of these probes was specifically blocked by alpha-methylmannoside and D-mannose and not by other monosaccharides. Thus, recognition of E-Con A and E. coli by the Fc receptor is dependent upon the mannose-specific interaction with lectin or lectin-like adhesions. These data demonstrate that ligands other than the classical IgG opsonins can bind to classical immune receptors for IgG through lectin-carbohydrate interactions. PMID:2445895

    2006-01-01

    Introduction: Continuously evolving medical standards of care, limited crew training time, and the inherent constraints of space flight necessitate regular revisions of the mission medical support infrastructure and methodology. A three-day Operational and Research Musculoskeletal Summit was held to review NASA s current strategy for preflight health maintenance and injury screening, risk mitigation for musculoskeletal injuries or syndromes, treatment methods during flight, and research topics to mitigate risks to astronaut health. The Summit also undertook consideration of the best evidence-based terrestrial musculoskeletal practices to recommend their adaptation for use in space. Methods: The types and frequencies of musculoskeletal injuries sustained by short- and long-duration astronauts were obtained from the Longitudinal Study of Astronaut Health. The Summit panel was comprised of experts from the clinical and research communities, as well as representatives from NASA Headquarters, the Astronaut corps, and the offices of JSC Medical Operations, JSC Human Adaptation and Countermeasures, Glenn Research Center Human Research, and Astronaut Strength Conditioning and Rehabilitation. Before the summit, panelists participated in a Web-based review of NASA s Space Medical Conditions List (SMCL). Results: The Summit generated seventy-five operational and research recommendations to the NASA Office of Space Medicine, including changes to the SMCL and to the musculoskeletal section of the ISS debrief questionnaire. From these recommendations, seven were assigned highest value and priority, and could be immediately adopted for the exploration architecture. Discussion: Optimized exercise and conditioning to improve performance and forestall musculoskeletal damage on orbit were the primary area of focus. Special attention was paid to exercise timing and muscle group specificity. The panel s recommendations are currently in various stages of consideration or integration

    Lake Michigan diversion accounting is the process used by the U. S. Army Corps of Engineers to quantify the amount of water that is diverted from the Lake Michigan watershed into the Illinois and Mississippi River Basins. A network of streamgages within the Chicago area waterway system monitor tributary river flows and the major river flow on the Chicago Sanitary and Ship Canal near Lemont as one of the instrumental tools used for Lake Michigan diversion accounting. The mean annual discharges recorded by these streamgages are used as additions or deductions to the mean annual discharge recorded by the main stream gaging station currently used in the Lake Michigan diversion accounting process, which is the Chicago Sanitary and Ship Canal near Lemont, Illinois (station number 05536890). A new stream gaging station, Summit Conduit near Summit, Illinois (station number 414757087490401), was installed on September 23, 2010, for the purpose of monitoring stage, velocity, and discharge through the Summit Conduit for the U.S. Army Corps of Engineers in accordance with Lake Michigan diversion accounting. Summit Conduit conveys flow from a small part of the lower Des Plaines River watershed underneath the Des Plaines River directly into the Chicago Sanitary and Ship Canal. Because the Summit Conduit discharges into the Chicago Sanitary and Ship Canal upstream from the stream gaging station at Lemont, Illinois, but does not contain flow diverted from the Lake Michigan watershed, it is considered a flow deduction to the discharge measured by the Lemont stream gaging station in the Lake Michigan diversion accounting process. This report offers a technical summary of the techniques and methods used for the collection and computation of the stage, velocity, and discharge data at the Summit Conduit near Summit, Illinois stream gaging station for the 2011 and 2012 Water Years.

    Spectral analysis of 46 days of record from a current meter deployed above the summit of Cross Seamount (approximately 300 km west of the Hawaiian Islands) indicates that the strongest current fluctuations were driven by the semidiurnal tide. The tides accounted for 28% of the variance in the current spectrum, were mainly baroclinic in character, and were propagated towards the west-northwest. The amplitude of the S2 current flowing parallel to the major axis of the current ellipse ranged between 4 and 9 cm-1 s. The S2 current was 1.5 times larger than the M2 current. This ratio is 4 times larger than is expected for this region of the Pacific and is not a general characteristics of flows over seamounts. Instantaneous current speeds over the seamount often exceeded 20 cm s-1 and were probably responsible for the small ripples observed on the sediment-covered regions of the summit. ?? 1990.

    Maunakea, a dormant shield volcano on the Big Island of Hawai'i, rises 13,796 feet above sea level, making it the highest point in the Pacific Basin. From sea floor to summit, it's the tallest mountain in the world. The high elevation, low air and light pollution, as well as dry weather year round make it the best location in the world for astronomy observations. The summit is home to 13 ground based telescope facilities. Like all alpine regions, it is an extremely fragile and unique ecosystem because of the harsh conditions and short growing seasons located at high altitudes. The summit is home to several federal and/or state protected species. It supports 11 species of arthropods found nowhere else on Earth. Most noted of these is the Wēkiu bug, whose habitat has been altered by the infrastructural development on the mountain. Arthropod habitat model development has highlighted gaps in climate information, for example, lack of climate precipitation data, snow data and reliable temperature data. Furthermore, in tropical regions, precipitation is the most variable climate component due to topography and local winds. The telescopes collect weather data for the purpose of knowing when it is dry and clear for astronomical observation. Although existing weather stations associated with the telescopes meet some weather and climate monitoring needs, it cannot address the full range of issues needed due to technological limitation and site design. Precipitation does not occur often and is likely to be in the form of snow or ice. Snow cover data has not been directly recorded despite astronomical recording of other meteorological data that began in the1960s. Therefore, the need to monitor the weather and climate in a long-term and well-calibrated way is critical for management of the ecosystems on the slopes of Maunakea. Long-term weather and climate monitoring stations are the primary building blocks for research partnerships, which encourage collaboration and ultimately

    Liver X receptor (LXR) is a nuclear receptor that plays a crucial role in orchestrating the trafficking of sterols between tissues. Treatment of mice with a potent and specific LXR agonist, T0901317, is associated with increased biliary cholesterol secretion, decreased fractional cholesterol absorption, and increased fecal neutral sterol excretion. Here we show that expression of two target genes of LXRalpha, the ATP-binding cassette (ABC) transporters Abcg5 and Abcg8, is required for both the increase in sterol excretion and the decrease in fractional cholesterol absorption associated with LXR agonist treatment. Mice expressing no ABCG5 and ABCG8 (G5G8(-/-) mice) and their littermate controls were treated for 7 days with T0901317. In wild type animals, treatment with the LXR agonist resulted in a 3-fold increase in biliary cholesterol concentrations, a 25% reduction in fractional cholesterol absorption, and a 4-fold elevation in fecal neutral sterol excretion. In contrast, the LXR agonist did not significantly affect biliary cholesterol levels, fractional cholesterol absorption, or neutral fecal sterol excretion in the G5G8(-/-) mice. Thus Abcg5 and Abcg8 are required for LXR agonist-associated changes in dietary and biliary sterol trafficking. These results establish a central role for ABCG5 and ABCG8 in promoting cholesterol excretion in vivo. PMID:12601003

    Atmospheric nitrate deposition to snow surfaces results from reactions of NOx (NO + NO2) with oxidants to produce HNO3. There has been enormous interest in using the isotopic composition of nitrate in ice cores to trace past NOx chemistry and sources. With the rapid cycling of NO and NO2, the oxygen isotopic signal reflects the oxidants that NOx reacts with to form nitrate, while the nitrogen isotopes could contain information about the NOx sources. In two spring/summer field seasons at Summit, Greenland (May-June 2010 and 2011), surface snow was collected at high time resolution and was measured for the complete N and O isotopic composition of nitrate. The oxygen isotopes (δ18O and Δ17O = δ17O - 0.52*δ18O) display the same very strong linear relationship (Δ17O = 0.46 * δ18O - 6.9, R2 = 0.9) in both seasons. This relationship indicates that there is very little photolysis of the nitrate at Summit and an unaltered nitrate signal is preserved in the snowpack. In addition, a suite of atmospheric measurements was made at Summit and none of the constituents measured show any correlation with concentration or isotopes of nitrate in the snow. This indicates that local chemistry is not contributing significantly to the nitrate in the snow. The combination of nitrogen and oxygen isotopes provides a richer picture of the data. There are three nitrate signatures that contribute to total nitrate deposition to Summit in both seasons. These sources can be described by the following isotopic compositions: δ15N, Δ17O, δ18O (per mil vs. air N2 or VSMOW): (1) -8, 27, 74 (2) 6, 40, 100 and (3) 16, 0, 23. While the same three nitrate sources are contributing in the two years, there is a very different balance of importance in 2010 compared to 2011. With limited source δ15N data it is difficult to assign each point to a specific NOx source, however the complete isotopic composition, atmospheric measurements and differences between the two seasons allow for tentative source

    Wound care issues and the ability to establish intravenous (IV) access among injured or ill crew members are a source of concern for NASA flight surgeons. Indeed, the microgravity environment and the remote nature of the International Space Station (ISS) pose unique challenges in diagnosing and treating an injured astronaut. Therefore, it is necessary to identify and adapt the best evidence based terrestrial practices regarding wound care, hemostasis, and IV access for use on the ISS. Methods: A panel of consultants was convened to evaluate the adequacy of the current ISS in-flight medical system for diagnosis and treatment of wounds and establishing IV access by a nonclinician crew medical officer. Participants were acknowledged experts in terrestrial wound care and/or operational medicine. Prior to the meeting, each panelist was encouraged to participate in a pre-summit online forum. Results: Eight external experts participated in a face-to-face meeting held at NASA-Johnson Space Center. Recommendations were made to augment the space station pharmacopoeia, as well as current wound care diagnostic, therapeutic, and deorbit criteria protocols. Additionally, suggestions were offered regarding IV access techniques and devices for use in the microgravity environment. Discussion: The results of the expert panel provide an evidence-based approach to the diagnosis and care of wounds in an injured astronaut on aboard the ISS. The results of the panel underscored the need for further research in wound therapy and IV access devices.

    UV irradiation of cellular DNA leads to the formation of a number of defined mutagenic DNA lesions. Here we report the discovery of new intrastrand C(4-8)G and G(8-4)C cross-link lesions in which the C(4) amino group of the cytosine base is covalently linked to the C(8) position of an adjacent dG base. The structure of the novel lesions was clarified by HPLC-MS/MS data for UV-irradiated DNA in combination with chemical synthesis and direct comparison of the synthetic material with irradiated DNA. We also report the ability to generate the lesions directly in DNA with the help of a photoactive precursor that was site-specifically incorporated into DNA. This should enable detailed chemical and biochemical investigations of these lesions. PMID:21425860

    With the majority of HIV infections resulting from mucosal transmission, induction of an effective mucosal immune response is thought to be pivotal in preventing transmission. HIV-specific IgA, but not IgG, has been detected in genital tract, seminal fluid, urethral swabs, urine and vaginal wash samples of HIV-negative sex workers and HIV-status discordant couples. Purified mucosal and plasma IgA from some individuals with highly exposed, persistently sero-negative (HEPS) can neutralize infection and present cross-clade neutralization activity though present at low levels. We generated a CD4i human monoclonal antibody (mAb) F425A1g8 and characterized the impact of its isotype variants on HIV neutralizing activity. The result showed that, in contrast to little neutralization by the F425A1g8 IgG1 in the absence of sCD4, the IgA1 variant of the antibody (Ab) displayed significant independent neutralization activity against a range of HIV clade B isolates in the absence of sCD4. The studies of the neutralizing function of IgA isotypes, and the functional relationship between different antigenic epitopes and IgA antibodies, may also suggest strategies for the intervention of virus transmission and spread within the mucosa of host, as well as serve to inform the design of vaccine strategies that may be more effective at preventing mucosal transmission. This research clearly suggests that IgA isotype because of its unique molecular structure may play an important role in HIV neutralization. PMID:23183895

    The C2S2: Climate Change Student Summit project has completed four years of activities plus a year-long longitudinal evaluation with demonstrated positive impacts beyond the life of the project on both students and teachers. This presentation will share the lessons learned about implementing this climate change science education program and suggest that it is a successful model that can be used to scale up from its Midwestern roots to achieve measurable national impact. A NOAA Environmental Literacy grant allowed ANDRILL (ANtarctic geological DRILLing) to grow a 2008 pilot program involving 2 Midwestern sites, to a program 4 years later involving 10 sites. The excellent geographical coverage included 9 of the U.S. National Climate Assessment regions defined by the U.S. Global Change Research Program. Through the delivery of two professional development (PD) workshops, a unique opportunity was provided for both formal and informal educators to engage their classrooms/audiences in understanding the complexities of climate change. For maximum contact hours, the PD experience was extended throughout the school year through the use of an online grouphub. Student teams were involved in a creative investigative science research and presentation experience culminating in a Climate Change Student Summit, an on-site capstone event including a videoconference connecting all sites. The success of this program was based on combining multiple aspects, such as encouraging the active involvement of scientists and early career researchers both in the professional development workshops and in the Student Summit. Another key factor was the close working relationships between informal and formal science entities, including involvement of informal science learning facilities and informal science education leaders. The program also created cutting-edge curriculum materials titled the ELF, (Environmental Literacy Framework with a focus on climate change), providing an earth systems

    The Grains for Health Foundation's Whole Grains Summit, held May 19-22, 2012 in Minneapolis, was the first meeting of its kind to convene >300 scientists, educators, food technologists, grain breeders, food manufacturers, marketers, health professionals, and regulators from around the world. Its goals were to identify potential avenues for collaborative efforts and formulate new approaches to whole-grains research and health communications that support global public health and business. This paper summarizes some of the challenges and opportunities that researchers and nutrition educators face in expanding the knowledge base on whole grains and health and in translating and disseminating that knowledge to consumers. The consensus of the summit was that effective, long-term, public-private partnerships are needed to reach across the globe and galvanize the whole-grains community to collaborate effectively in translating whole-grains science into strategies that increase the availability and affordability of more healthful, grain-based food products. A prerequisite of that is the need to build trust among diverse multidisciplinary professionals involved in the growing, producing, marketing, and regulating of whole-grain products and between the grain and public health communities.

  7. A look behind the arms control agenda at the US-Russian and Sino-US summits

    When President Bill Clinton met in New York with Russian President Boris Yeltsin on October 23 and Chinese President Jiang Zemin the following day, the leaders discussed a broad spectrum of arms control issues-including START II ratification, limits on Russian conventional weapons in the Caucasus, the nuclear test ban treaty, nuclear exports to Iran and NATO expansion. The crisis in Bosnia, however, dominated the administration`s pre- and post-summit briefings as well as the media`s coverage of the meetings. On October 20, the Arms Control Association (ACA) held a news conference to highlight the key arms control issues involved in the two sets of talks. Because these vital national security issues were virtually ignored by the press, the ACA press briefing remains the most comprehensive coverage of the full range of issues that were, in fact, addressed at the mini-summits. Panel speakers included Spurgeon M. Keeny, Jr., ACA president and executive director and former deputy director of the Arms Control and Disarmament Agency; Jack Mendelsohn, ACA deputy director and a former member of the US SALT II and START I delegations; Stanley Resor, ACA board chairman and former chief US delegate to the Mutual and Balanced Force Reduction talks, former defense undersecretary for policy and former secretary of the Army; and William Dircks, director of the Atlantic Council`s Program on Nuclear Policy and former deputy director general of the International Atomic Energy Agency.

    2015-01-01

    Simultaneous summit and rift zone eruptions at Kīlauea starting in 2008 reflect a shallow eruptive plumbing system inundated by a bourgeoning supply of new magma from depth. Olivine-hosted melt inclusions, host glass, and bulk lava compositions of magma erupted at both the summit and east rift zone demonstrate chemical continuity at both ends of a well-worn summit-to-rift pipeline. Analysis of glass within dense-cored lapilli erupted from the summit in March – August 2008 show these are not samplings of compositionally distinct magmas stored in the shallow summit magma reservoir, but instead result from remelting and assimilation of fragments from conduit wall and vent blocks. Summit pyroclasts show the predominant and most primitive component erupted to be a homogenous, relatively trace-element-depleted melt that is a compositionally indistinguishable from east rift lava. Based on a “top-down” model for the geochemical variation in east rift zone lava over the past 30 years, we suggest that the apparent absence of a 1982 enriched component in melt inclusions, as well as the proposed summit-rift zone connectivity based on sulfur and mineral chemistry, indicate that the last of the pre-1983 magma has been flushed out of the summit reservoir during the surge of mantle-derived magma from 2003-2007.

    The Earth Summit (United Nations Conference on Environmental and Development (UNCED)), held in Rio de Janeiro in June 1992, was unique in the history of international conferences. Never before had so many heads of state participated in such an international negotiation. UNCED was also unique in both the breadth of environmental and development issues addressed and in the nature of the cross-cutting dimensions that were examined (for example, from poverty, population growth, and the role of indigenous peoples to unsustainable patterns of consumption (in the North), the role of women, and technology transfer). The chapter devoted to oceans and coasts was the longest and, in some ways, the most comprehensive, of the 40 chapters making up the action plan (Agenda 21) that was approved at Rio. This article provides an overview of the events leading up the Earth Summit, describes the principal outputs of the conference and their potential effects on ocean and coastal governance, discusses the main tension seen at UNCED and some of the negotiating processes, and, finally, considers current efforts at implementation of its recommendations. 43 refs., 1 fig.

    During the opening session of the EFRC Summit, Senator Jeff Bingaman (D-NM) explained how the EFRCs play an important role in the U.S. energy innovation ecosystem. The 2011 EFRC Summit and Forum brought together the EFRC community and science and policy leaders from universities, national laboratories, industry and government to discuss "Science for our Nation's Energy Future." In August 2009, the Office of Science established 46 Energy Frontier Research Centers. The EFRCs are collaborative research efforts intended to accelerate high-risk, high-reward fundamental research, the scientific basis for transformative energy technologies of the future. These Centers involve universities, national laboratories, nonprofit organizations, and for-profit firms, singly or in partnerships, selected by scientific peer review. They are funded at $2 to $5 million per year for a total planned DOE commitment of $777 million over the initial five-year award period, pending Congressional appropriations. These integrated, multi-investigator Centers are conducting fundamental research focusing on one or more of several “grand challenges” and use-inspired “basic research needs” recently identified in major strategic planning efforts by the scientific community. The purpose of the EFRCs is to integrate the talents and expertise of leading scientists in a setting designed to accelerate research that transforms the future of energy and the environment.

The selective agenda and OCHAs lack of success in engaging pre-meeting political participation not only hampered the Summit’s ability to deal with global issues and institutional reform, but also alienated it from leading aid agencies and governments. The UN’s failure to commit to humanitarian principles and global disarray of the humanitarian system indicates the need for extensive reform or a new global humanitarian body. This agency needs to employ a decentralized model to manage aid funds, assume coordination of international responses, resolve civil-military coordination, cater for people affected by both conflict and disasters, and professionalize the humanitarian career.  PMID:27679738

    The potential for space weather effects has been increasing significantly in recent years. For instance, in 2008 airlines flew about 8000 transpolar flights, which experience greater exposure to space weather than nontranspolar flights. This is up from 368 transpolar flights in 2000, and the number of such flights is expected to continue to grow. Transpolar flights are just one example of the diverse technologies susceptible to space weather effects identified by the National Research Council's Severe Space Weather Events—Understanding Societal and Economic Impacts: A Workshop Report (2008). To discuss issues related to the increasing need for reliable space weather information, experts from industry and government agencies met at the third summit of the Commercial Space Weather Interest Group (CSWIG) and the National Oceanic and Atmospheric Administration's (NOAA) Space Weather Prediction Center (SWPC), held 30 April 2009 during Space Weather Week (SWW), in Boulder, Colo.

    This study aimed to present currently known basic science and on-ice influences of sport-related concussion (SRC) in hockey, building upon the Ice Hockey Summit I action plan (2011) to reduce SRC. The prior summit proceedings included an action plan intended to reduce SRC. As such, the proceedings from Summit I served as a point of departure for the science and discussion held during Summit II (Mayo Clinic, Rochester, MN, October 2013). Summit II focused on (1) Basic Science of Concussions in Ice Hockey: Taking Science Forward, (2) Acute and Chronic Concussion Care: Making a Difference, (3) Preventing Concussions via Behavior, Rules, Education, and Measuring Effectiveness, (4) Updates in Equipment: Their Relationship to Industry Standards, and (5) Policies and Plans at State, National, and Federal Levels To Reduce SRC. Action strategies derived from the presentations and discussion described in these sectors were voted on subsequently for purposes of prioritization. The following proceedings include the knowledge and research shared by invited faculty, many of whom are health care providers and clinical investigators. The Summit II evidence-based action plan emphasizes the rapidly evolving scientific content of hockey SRC. It includes the most highly prioritized strategies voted on for implementation to decrease concussion. The highest-priority action items identified from the Summit include the following: (1) eliminate head hits from all levels of ice hockey, (2) change body checking policies, and (3) eliminate fighting in all amateur and professional hockey.

    Advances in PET and SPECT and imaging hardware and software are vastly improving the noninvasive evaluation of myocardial perfusion and function. PET perfusion imaging has benefitted from the introduction of novel detectors that now allow true 3D imaging, and precise attenuation correction (AC). These developments have also resulted in perfusion images with higher spatial and contrast resolution that may be acquired in shorter protocols and/or with less patient radiation exposure than traditional PET or SPECT studies. Hybrid PET/CT cameras utilize transmission computed tomographic (CT) scans for AC, and offer the additional clinical advantages of evaluating coronary calcium and myocardial anatomy but at a higher cost than PET scanners that use (68)Ge radioactive line sources. As cardiac PET systems continue to improve, dedicated cardiac SPECT systems are also undergoing a profound change in their design. The scintillation camera general purpose design is being replaced with systems with multiple detectors focused on the heart yielding 5 to 10 times the sensitivity of conventional SPECT. As a result, shorter acquisition times and/or lower tracer doses produce higher quality SPECT images than were possible before. This article reviews these concepts and compares the attributes of PET and SPECT instrumentation. PMID:25824018

  16. Deep magma body beneath the summit and rift zones of Kilauea Volcano, Hawaii

    A magnitude 7.2 earthquake in 1975 caused the south flank of Kilauea Volcano, Hawaii, to move seaward in response to slippage along a deep fault. Since then, a large part of the volcano's edifice has been adjusting to this perturbation. The summit of Kilauea extended at a rate of 0.26 meter per year until 1983, the south flank uplifted more than 0.5 meter, and the axes of both the volcano's rift zones extended and subsided; the summit continues to subside. These ground-surface motions have been remarkably steady and much more widespread than those caused by either recurrent inflation and deflation of the summit magma chamber or the episodic propagation of dikes into the rift zones. Kilauea's magmatic system is, therefore, probably deeper and more extensive than previously thought; the summit and both rift zones may be underlain by a thick, near vertical dike-like magma system at a depth of 3 to 9 kilometers.

  17. Transcription of viral late genes is dependent on expression of the viral intermediate gene G8R in cells infected with an inducible conditional-lethal mutant vaccinia virus.

    There are three temporal classes of vaccinia virus genes: early, intermediate, and late. The object of this study was to determine the effects on virus replication of regulating the expression of G8R, an intermediate gene that encodes a late transcription factor. We inserted the lac operator adjacent to the RNA start site of the G8R gene in a recombinant vaccinia virus that constitutively expresses the Escherichia coli lac repressor to make expression of the G8R gene dependent on the inducer isopropyl-beta-D-thiogalactopyranoside (IPTG). In case repression would not be complete, we also weakened the promoter of the G8R gene by making a single-nucleotide substitution designed to reduce its basal level of transcription. The mutant virus replicated well in the presence of the inducer, although synthesis of the G8R-encoded 30,000-M(r) protein was only 10% of that of the wild-type virus. In the absence of IPTG, (i) synthesis of the G8R protein was inhibited by more than 99% relative to that of the wild-type virus, (ii) synthesis of early and intermediate mRNAs appeared to be unaffected, (iii) intermediate proteins accumulated to higher than normal levels, (iv) synthesis of late mRNA and protein was reduced by about 90%, (v) viral DNA was replicated but incompletely resolved concatemeric molecules accumulated, (vi) not even the earliest stages of virion assembly were detectable by transmission electron microscopy, and (vii) virus yield under one-step growth conditions and plaque formation were 10(-3) and 10(-4) times the wild-type values, respectively. The defect in late gene expression could be overcome by transfection of a G8R gene that was not under lac operator control, as well as by addition of IPTG, further demonstrating the specificity of the repression. The correlation between decreased expression of the G8R intermediate gene and inhibition of late mRNA synthesis is consistent with the notion that the G8R product serves as an essential late transcription factor

    The opening of a new vent within Halema'uma'u Crater in March 2008 ended a 26-year period of no eruptive activity at the summit of Kilauea Volcano. It also heralded the first explosive activity at Kilauea's summit since 1924 and the first of eight discrete explosive events in 2008. At the onset of the eruption, the Hawaiian Volcano Observatory (HVO) initiated a rigorous program of sample collection to provide a temporally constrained suite of tephra samples for petrographic, geochemical, and isotopic studies. Petrologic studies help us understand conditions of magma generation at depth; processes related to transport, storage, and mixing of magma within the shallow summit region; and specific circumstances leading to explosive eruptions. This report provides a catalog of tephra samples erupted at Kilauea's summit from March 19, 2008, through the end of 2008. The Kilauea 2008 Summit Sample Catalog is tabulated in the accompanying Microsoft Excel file, of2009-1134.xls (four file types linked on right). The worksheet in this file provides sampling information and sample descriptions. Contextual information for this catalog is provided below and includes (1) a narrative of 2008 summit eruptive activity, (2) a description of sample collection methods, (3) a scheme for characterizing a diverse range in tephra lithology, and (4) an explanation of each category of sample information (column headers) in the Microsoft Excel worksheet.

    2013-12-01

    New and advanced technologies in firn studies continue to emerge in both remote sensing tools and the platforms that deploy them. A new autonomous robot, called GROVER, was tested and deployed in May 2013 at Summit, Greenland. The robot operates a 8 GHz bandwidth frequency-modulated continuous-wave (FMCW) radar capable of imaging the near-surface firn at very high vertical resolution (~2 cm). The radar penetrated to depths of ~10 m with identifiable annual layers. Here we briefly describe GROVER's capabilities and applications for firn studies. We present the nearly 25 km of accumulation measurements derived from annual layering in the radar echograms. The GROVER-made measurements are compared to radar-derived accumulation from previous studies using a similar FMCW system in 2009 pulled by a snowmobile, as well as, with airborne laser altimetry and GPS measurements taken over the roved lines. Discrepancies and similarities between the measurement methods are investigated and explained. The robot-based firn echograms are also used to estimate the depth and extent of the 2012 melt layer over the roved lines. Near-surface radars have proven useful for monitoring and calculating snow and firn processes such as SWE and accumulation; moving firn studies onto an autonomous rover can reduce costs and increase spatial coverage for validation of future satellite missions.

    Undulating bands of dark and light sand, sloping dunes, and scattered cobbles form an apron around a ridge of light-colored rock that stands in bold relief against distant plains, as viewed by NASA's 'Spirit' rover from the top of 'Husband Hill' on Mars. 'The view of the summit is spectacular where we are right now,' said geologist Larry Crumpler, with the New Mexico Museum of Natural History and Science, Albuquerque.

    From here, Spirit is looking north-northeast en route to examining more of the local geology of the 'Columbia Hills' in Gusev Crater. A few days after taking this picture, Spirit investigated the small, sinuous drifts on the left, located north-northeast of the rover's position in this image. The last previous time Spirit examined a drift was on the rim of 'Bonneville Crater' almost 500 martian days, or sols, ago, in March 2004.

    The largest light-colored rock in the foreground is nicknamed 'Whittaker.' The cliff beyond it and slightly to the left is nicknamed 'Tenzing.' The highest rock on the ridge ahead has been dubbed 'Hillary.' Science team members selected the nicknames in honor of the earliest climbers to scale Mount Everest on Earth. This view covers approximately 50 degrees of the compass from left to right. It is a mosaic assembled from frames Spirit took with the panoramic camera on sol 603 (Sept. 13, 2005). It was taken through a blue (430-nanometer) filter and is presented as a cylindrical projection.

    This report is the outcome of the meeting: “Environmental and Human Health Consequences of Arsenic”, held at the MDI Biological Laboratory in Salisbury Cove, Maine, August 13–15, 2014. Human exposure to arsenic represents a significant health problem worldwide that requires immediate attention according to the World Health Organization (WHO). One billion people are exposed to arsenic in food and more than 200 million people ingest arsenic via drinking water at concentrations greater than international standards. Although the U.S. Environmental Protection Agency (EPA) has set a limit of 10 micrograms per liter (10 μg/L) in public water supplies and the WHO has recommended an upper limit of 10 μg/L, recent studies indicate that these limits are not protective enough. In addition, there are currently few standards for arsenic in food. Those who participated in the Summit support citizens, scientists, policymakers, industry and educators at the local, state, national and international levels to: (1) Establish science-based evidence for setting standards at the local, state, national, and global levels for arsenic in water and food; (2) Work with government agencies to set regulations for arsenic in water and food, to establish and strengthen non-regulatory programs, and to strengthen collaboration among government agencies, NGOs, academia, the private sector, industry and others; (3) Develop novel and cost-effective technologies for identification and reduction of exposure to arsenic in water; (4) Develop novel and cost-effective approaches to reduce arsenic exposure in juice, rice, and other relevant foods, and (5) Develop an Arsenic Education Plan to guide the development of science curricula as well as community outreach and education programs that serve to inform students and consumers about arsenic exposure and engage them in well water testing and development of remediation strategies.

    The World Summit on Sustainable Development (WSSD) was held in Johannesburg in 2002 to review progress since the Rio conference in 1992, and to agree a new global deal on sustainable development. Unlike its predecessor, it was primarily concerned with implementation rather than with new treaties and targets, although a number of new targets were agreed, for example one on sanitation. Failure to agree a target on renewable energy was regarded as a major disappointment of the conference. While relatively modest in its achievements, and with difficulties in achieving consensus in key areas such as energy, trade, finance and globalisation, WSSD nevertheless succeeded in placing sustainable development back on the political agenda, giving new impetus, in particular to the environment and development needs of Africa, with a strong focus on local issues like household energy, water and sanitation. Health was singled out as one of five priority areas, along with water, energy, agriculture and biodiversity, and was devoted a separate chapter in the resulting Plan of Implementation, which highlighted a range of environmental health issues as well as issues relating to health services, communicable and non-communicable diseases. A number of new partnerships were formed at WSSD, including the Healthy Environments for Children Alliance (HECA) launched by WHO, which will form an important platform for implementation. The Commission on Sustainable Development has been designated main responsibility for monitoring and follow up, with its programme of work reorganised to focus on thematic clusters of issues. From the perspective of health, WSSD must be seen as a reaffirmation of the central place of health on the sustainable development agenda, and in the broader context of a process which began in Rio and was given added impetus with the Monterrey Financing for Development conference and the World Trade Organisation meeting held in Doha.

    Mountain summits present a unique challenge to manage sustainably: they are ecologically important and, in many circumstances, under high demand for recreation and tourism activities. This article presents recent advances in the assessment of resource conditions and visitor disturbance in mountain summit environments, by drawing on examples from a multiyear, interdisciplinary study of summits in the northeastern United States. Primary impact issues as a consequence of visitor use, such as informal trail formation, vegetation disturbance, and soil loss, were addressed via the adaption of protocols from recreation ecology studies to summit environments. In addition, new methodologies were developed that provide measurement sensitivity to change previously unavailable through standard recreation monitoring protocols. Although currently limited in application to the northeastern US summit environments, the methods presented show promise for widespread application wherever summits are in demand for visitor activities.

    This article reports on the design, evaluation framework, and results from the Meta-Leadership Summit for Preparedness Initiative. The Meta-Leadership Summit for Preparedness was a 5-year initiative based on the premise that national preparedness and emergency response is not solely the responsibility of government. From 2006 to 2011, 36 Meta-Leadership Summits were delivered in communities across the country. Summits were customized, 10-hour leadership development, networking, and community action planning events. They included participation from targeted federal, state, local, nonprofit/philanthropic, and private sector leaders who are directly involved in decision making during a major community or state-wide emergency. A total of 4,971 government, nonprofit, and business leaders attended Meta-Leadership Summits; distribution of attendees by sector was balanced. Ninety-three percent of respondents reported the summit was a valuable use of time, 91% reported the overall quality as "good" or "outstanding," and 91% would recommend the summit to their colleagues. In addition, approximately 6 months after attending a summit, 80% of respondents reported that they had used meta-leadership concepts or principles. Of these, 93% reported that using meta-leadership concepts or principles had made a positive difference for them and their organizations. The Meta-Leadership Summit for Preparedness Initiative was a value-added opportunity for communities, providing the venue for learning the concepts and practice of meta-leadership, multisector collaboration, and resource sharing with the intent of substantively improving preparedness, response, and recovery efforts.

    The Cerro Summit quadrangle covers 58 square miles of dissected plateau on the south flank of the Gunnison uplift in southwestern Colorado. It lies east of the Uncompahgre River valley and south of the Black Canyon of the Gunnison River. Rocks dip gently in most of the quadrangle, but they are locally upturned and faulted on the margin of the Gunnison uplift and are intensely deformed in the core of the uplift. The rocks exposed are of Precambrian, late Mesozoic, and Cenozoic age. Precambrian rocks include metasedimentary schist and gneiss, granitic pegmatite, and olivine gabbro. The oldest Mesozoic rocks exposed are continental, fresh-water, and lagoonal deposits in the Late Jurassic Entrada Sandstone, Wanakah Formation, and Morrison Formation. Channel-fill deposits that unconformably overlie the Jurassic rocks are possibly the Burro Canyon Formation of Early Cretaceous age. Upper Cretaceous rocks include marine and nearshore deposits of the Dakota Sandstone, Mancos Shale, and Pictured Cliffs Sandstone, and the fresh- and brackish-water sandstone, shale, and coal of the Fruitland Formation. Rocks of Late Cretaceous age that crop out in the adjacent Cimarron Ridge area may also have been deposited in this quadrangle but are now eroded; these rocks include the nonmarine Kirtland Shale and an unnamed volcanic conglomerate and tuff breccia. Nine faunal zones in the Mancos Shale help to establish the correct correlation of units in the Upper Cretaceous. The Pictured Cliffs Sandstone, Fruitland Formation, and Kirtland Shale of the Cerro Summit area have been mapped by some geologists as the Mesaverde Formation. Fossils indicate that the rocks are younger than the type Mesaverde. The unnamed volcanic rocks represent major volcanism in nearby areas. A Late Cretaceous (Maestrichtian) age for the volcanism is indicated by palynological evidence and an isotopic age of approximately 66 million years. Middle Tertiary rocks are conglomerate and tuff breccia. Upper Tertiary or

    Firn-temperature profiles are calculated in a thermal model using continuous surface temperatures derived from Automatic Weather Station (AWS) data and passive microwave data in the Greenland Summit region during the period 1987-1999. The results show that significant interannual variations of mean summer (June to August) and annual temperatures occur in the top 15 m, in addition to the normal seasonal cycle of firn temperature. At 5 m depth, the seasonal cycle is damped to 13% of the surface seasonal amplitude, but even at 15 m about 1% or 0.6 C of the seasonal cycle persists. Both summer and mean annual temperatures decrease from 1987 to 1992, followed by a general increasing trend. Interannual variability is 5 C at the surface, but only is only dampened to 3.2 C at 10 m depth and 0.7 C at 15 m depth. Dampening of the interannual variability with depth is slower than dampening of the seasonal cycle, because of the longer time constant of the interannual variation. The warmer spring and summer temperatures experienced in the top 5 m, due to both the seasonal cycle and interannual variations, affect the rate of firn densification, which is non-linearly dependent on temperature. During the 12 year period 1987-1999, the mean annual surface temperature is -29.2 C, and the mean annual 15 m temperature is -30. 1 C, which is more than 1 C warmer than a 15-m borehole temperature representing the period of about 1959 and warmer than the best-fit temperature history by Alley and Koci back to 1500 A.D..

  12. Descent from the Summit of 'Husband Hill' (False Color)

    NASA Technical Reports Server (NTRS)

    2005-01-01

    In late November 2005 while descending 'Husband Hill,' NASA's Mars Exploration Rover Spirit took the most detailed panorama so far of the 'Inner Basin,' the rover's next target destination. Spirit acquired the 405 individual images that make up this 360-degree view of the surrounding terrain using five different filters on the panoramic camera. The rover took the images on Martian days, or sols, 672 to 677 (Nov. 23 to 28, 2005 -- the Thanksgiving holiday weekend).

    This image is a false-color rendering using camera's 750-, 530-, and 430-nanometer filters, emphasizing some colors more than others to enhance striking but subtle color differences among rocks, soils, hills, and plains.

    'Home Plate,' a bright, semi-circular feature scientists hope to investigate, is harder to discern in this image than in earlier views taken from higher up the hill. Spirit acquired this more oblique view, known as the 'Seminole panorama,' from about halfway down the south flank of Husband Hill, 50 meters (164 feet) or so below the summit. Near the center of the panorama, on the horizon, are 'McCool Hill' and 'Ramon Hill,' named, like Husband Hill, in honor of the fallen astronauts of the space shuttle Columbia. Husband Hill is visible behind the rover, on the right and left sides of the panorama. An arc of rover tracks made while avoiding obstacles and getting into position to examine rock outcrops can be traced over a long distance by zooming in to explore the panorama in greater detail.

    Spirit is now significantly farther downhill toward the center of this panorama, en route to Home Plate and other enigmatic soils and outcrop rocks in the quest to uncover the history of Gusev Crater and the 'Columbia Hills.'

    At the UN Conference on the Environment and Development, commonly referred to as the Earth Summit, questions of population and family planning tended to become politicized and controversial. The Catholic Church succeeded in eliminating all specific references to family planning and contraception in the official documents. The UN General Assembly Resolution calling for convocation of the conference and the early planning documents made no reference to the impact of demographic growth on the environment. But in the months preceding the conference, the UN Population Fund and other interest groups succeeded in calling greater attention to population questions. The Vatican exercised its influence to change the wording concerning population, aided by disagreement between the developed and developing countries on the weight that should be given to overconsumption in the developed world and population growth in the developing countries. The wealthier countries, the poor countries, the Vatican, feminist groups opposing coercive population control, and ecological and demographic interest groups supporting family planning were the main contenders in the battle to influence the eventual statement. The words "family planning" were replaced in the text by "responsible planning of family size, in a spirit of liberty and dignity and in accordance with personal values, taking into account moral and cultural considerations". Although it was impossible to change the timid wording during the Conference, concern about rapid growth was expressed in numerous Conference statements. The final document lacked vigor in calling for rapid stabilizing of population growth and universal access to family planning. But the significant result of the Conference as a whole was that the intrinsic links between population dynamics, the environment, and economic development were acknowledged. PMID:12319664

    Policies supporting the rapid and open sharing of genomic data have directly fueled the accelerated pace of discovery in large-scale genomics research. The proteomics community is starting to implement analogous policies and infrastructure for making large-scale proteomics data widely available on a precompetitive basis. On August 14, 2008, the National Cancer Institute (NCI) convened the "International Summit on Proteomics Data Release and Sharing Policy" in Amsterdam, The Netherlands, to identify and address potential roadblocks to rapid and open access to data. The six principles agreed upon by key stakeholders at the summit addressed issues surrounding (1) timing, (2) comprehensiveness, (3) format, (4) deposition to repositories, (5) quality metrics, and (6) responsibility for proteomics data release. This summit report explores various approaches to develop a framework of data release and sharing principles that will most effectively fulfill the needs of the funding agencies and the research community.

    INTRODUCTION The area covered by this map includes parts of four U.S. Geological Survey (USGS) 7.5' topographic quadrangles (Kilauea Crater, Volcano, Ka`u Desert, and Makaopuhi). It encompasses the summit, upper rift zones, and Koa`e Fault System of Kilauea Volcano and a part of the adjacent, southeast flank of Mauna Loa Volcano. The map is dominated by products of eruptions from Kilauea Volcano, the southernmost of the five volcanoes on the Island of Hawai`i and one of the world's most active volcanoes. At its summit (1,243 m) is Kilauea Crater, a 3 km-by-5 km collapse caldera that formed, possibly over several centuries, between about 200 and 500 years ago. Radiating away from the summit caldera are two linear zones of intrusion and eruption, the east and the southwest rift zones. Repeated subaerial eruptions from the summit and rift zones have built a gently sloping, elongate shield volcano covering approximately 1,500 km2. Much of the volcano lies under water: the east rift zone extends 110 km from the summit to a depth of more than 5,000 m below sea level; whereas, the southwest rift zone has a more limited submarine continuation. South of the summit caldera, mostly north-facing normal faults and open fractures of the Koa`e Fault System extend between the two rift zones. The Koa`e Fault System is interpreted as a tear-away structure that accommodates southward movement of Kilauea's flank in response to distension of the volcano perpendicular to the rift zones. This digital release contains all the information used to produce the geologic map published as USGS Geologic Investigations Series I-2759 (Neal and Lockwood, 2003). The main component of this digital release is a geologic map database prepared using ArcInfo GIS. This release also contains printable files for the geologic map and accompanying descriptive pamphlet from I-2759.

  18. Kilauea summit overflows: Their ages and distribution in the Puna District, Hawai'i

    The tube-fed pahoehoe lava flows covering much of the northeast flank of Kilauea Volcano are named the 'Aila'au flows. Their eruption age, based on published and six new radiocarbon dates, is approximately AD 1445. The flows have distinctive paleomagnetic directions with steep inclinations (40??-50??) and easterly declinations (0??-10??E). The lava was transported ~40 km from the vent to the coast in long, large-diameter lava tubes; the longest tube (Kazumura Cave) reaches from near the summit to within several kilometers of the coast near Kaloli Point. The estimated volume of the 'Aila'au flow field is 5.2 ?? 0.8 km3, and the eruption that formed it probably lasted for approximately 50 years. Summit overflows from Kilauea may have been nearly continuous between approximately AD 1290 and 1470, during which time a series of shields formed at and around the summit. The 'Aila'au shield was either the youngest or the next to youngest in this series of shields. Site-mean paleomagnetic directions for lava flows underlying the 'Aila'au flows form only six groups. These older pahoehoe flows range in age from 2750 to 2200 years. Lava flows from most of these summit eruptions also reached the coast, but none appears as extensive as the 'Aila'au flow field. The chemistry of the melts erupted during each of these summit overflow events is remarkably similar, averaging approximately 6.3 wt.% MgO near the coast and 6.8 wt.% MgO near the summit. The present-day caldera probably formed more recently than the eruption that formed the 'Aila'au flows (estimated termination ca. AD 1470). The earliest explosive eruptions that formed the Keanakako'i Ash, which is stratigraphically above the 'Aila'au flows, cannot be older than this age.

  3. Carbon dioxide emission rate of Kīlauea Volcano: Implications for primary magma and the summit reservoir

    2002-01-01

     We report a CO2 emission rate of 8500 metric tons per day (t d−1) for the summit of Kīlauea Volcano, several times larger than previous estimates. It is based on three sets of measurements over 4 years of synchronous SO2 emission rates and volcanic CO2/SO2concentration ratios for the summit correlation spectrometer (COSPEC) traverse. Volcanic CO2/SO2 for the traverse is representative of the global ratio for summit emissions. The summit CO2 emission rate is nearly constant, despite large temporal variations in summit CO2/SO2 and SO2 emission rates. Summit CO2 emissions comprise most of Kīlauea's total CO2 output (∼9000 t d−1). The bulk CO2 content of primary magma determined from CO2emission and magma supply rate data is ∼0.70 wt %. Most of the CO2 is present as exsolved vapor at summit reservoir depths, making the primary magma strongly buoyant. Turbulent mixing with resident reservoir magma, however, prevents frequent eruptions of buoyant primary magma in the summit region. CO2 emissions confirm that the magma supply enters the edifice through the summit reservoir. A persistent several hundred parts per million CO2 anomaly arises from the entry of magma into the summit reservoir beneath a square kilometer area east of Halemaumau pit crater. Since most of the CO2 in primary magma is degassed in the summit, the summit CO2 emission rate is an effective proxy for the magma supply rate. Both scrubbing of SO2 and solubility controls on CO2and S in basaltic melt cause high CO2/SO2 in summit emissions and spatially uncorrelated distributions of CO2 and SO2 in the summit plume.

    Introduction Haemoglobin A1c (HbA1c) is widely used in the management of diabetes. Therefore, the reliability and comparability among different analytical methods for its detection have become very important. Materials and methods A comparative evaluation of the analytical performances (precision, linearity, accuracy, method comparison, and interferences including bilirubin, triglyceride, cholesterol, labile HbA1c (LA1c), vitamin C, aspirin, fetal haemoglobin (HbF), and haemoglobin E (Hb E)) were performed on Capillarys 2 Flex Piercing (Capillarys 2FP) (Sebia, France), Tosoh HLC-723 G8 (Tosoh G8) (Tosoh, Japan), Premier Hb9210 (Trinity Biotech, Ireland) and Roche Cobas c501 (Roche c501) (Roche Diagnostics, Germany). Results A good precision was shown at both low and high HbA1c levels on all four systems, with all individual CVs below 2% (IFCC units) or 1.5% (NGSP units). Linearity analysis for each analyzer had achieved a good correlation coefficient (R2 > 0.99) over the entire range tested. The analytical bias of the four systems against the IFCC targets was less than ± 6% (NGSP units), indicating a good accuracy. Method comparison showed a great correlation and agreement between methods. Very high levels of triglycerides and cholesterol (≥ 15.28 and ≥ 8.72 mmol/L, respectively) led to falsely low HbA1c concentrations on Roche c501. Elevated HbF induced false HbA1c detection on Capillarys 2FP (> 10%), Tosoh G8 (> 30%), Premier Hb9210 (> 15%), and Roche c501 (> 5%). On Tosoh G8, HbE induced an extra peak on chromatogram, and significantly lower results were reported. Conclusions The four HbA1c methods commonly used with commercial analyzers showed a good reliability and comparability, although some interference may falsely alter the result. PMID:27812304

    2010-07-01

    Over the past three decades, the staff of the MMT observatory used a variety of techniques to predict the summit wind characteristics including wind tunnel modeling and the release of smoke bombs. With the planned addition of a new instrument repair facility to be constructed on the summit of Mt. Hopkins, new computational fluid dynamic (CFD) models were made to determine the building's influence on the thermal environment around the telescope. The models compared the wind profiles and density contours above the telescope enclosure with and without the new building. The results show the steeply-sided Mount Hopkins dominates the summit wind profiles. In typical winds, the height of the telescope remains above the ground layer and is sufficiently separated from the new facility to insure the heat from the new building does not interfere with the telescope. The results also confirmed the observatories waste heat exhaust duct location needs to be relocated to prevent heat from being trapped in the wind shadow of the new building and lofting above the telescope. These useful models provide many insights into understanding the thermal environment of the summit.

    The flattop mountains (tepuis) of South America are ancient remnants of the Precambrian Guiana Shield plateau. The tepui summits, isolated by their surrounding cliffs that can be up to 1000 m tall, are thought of as "islands in the sky," harboring relict flora and fauna that underwent vicariant speciation due to plateau fragmentation. High endemicity atop tepui summits support the idea of an ancient "Lost World" biota. However, recent work suggests that dispersal between lowlands and summits has occurred long after tepui formation indicating that tepui summits may not be as isolated from the lowlands as researchers have long suggested. Neither view of the origin of the tepui biota (i.e., ancient vicariance vs. recent dispersal) has strong empirical support owing to a lack of studies. We test diversification hypotheses of the Guiana Shield highlands by estimating divergence times of an endemic group of treefrogs, Tepuihyla. We find that diversification of this group does not support an ancient origin for this taxon; instead, divergence times among the highland species are 2-5 Ma. Our data indicate that most highland speciation occurred during the Pliocene. Thus, this unparalleled landscape known as "The Lost World" is inhabited, in part, not by Early Tertiary relicts but neoendemics.

    On 2 May 2013, the European Scientific Working group on Influenza (ESWI) held its third influenza summit at the Institute of European Studies at the Free University of Brussels. ESWI brought together more than 90 representatives of organizations of healthcare providers, senior citizens, at-risk patients and public health authorities for a day of tailored lectures, Q&A sessions and networking. Since recent studies, surveys and reviews have shed new light on some of the most intriguing influenza issues, the Summit faculty translated the newest scientific data into practice. The first part of the Summit programme focused on the current flu status in Europe, paying special attention to the protection of pregnant women and the elderly as well as to the issues of vaccine safety and effectiveness. The programme continued to highlight future challenges and evolutions like novel antiviral drugs against influenza, improved flu vaccines and the prospect of a universal flu vaccine. The annual ESWI flu summits are the pinnacles of ESWI's efforts to bridge the gap between science and society. ESWI's members are convinced that the fight against influenza can only be won when all parties are well informed and ready to work together.

    The Summit Framework is a gyrokinetic particle-in-cell turbulence simulation environment written in Fortran90 providing a unified object-based facility for sharing common components in a massively parallel setting [http://www.nersc.gov/scidac/summit/]. The Summit Framework is part of the US Department of Energy SciDAC Plasma Microturbulence Project. Work is under way to include kinetic electron models and electromagnetic effects, realistic magnetic geometry and global effects under one software environment. General geometry, realistic equilibria capabilities are being incorporated in the Summit Framework through the pg3eq_nc module, itself an extension of the circular geometry pg3eq module [Dimits et al. Phys. Rev. Letts 77, 71 (1996)]. These modules use quasi-ballooning coordinates to solve the three-dimensional, toroidal, delta-f, gyrokinetic equations for ions in order to model ITG turbulence. Realistic geometry is introduced through an interface to data from the EFIT equilibrium code[ http://fusion.gat.com/efit/]. Massively parallel implementation has been effected using MPI. Successful nonlinear comparisons for a sample shaped and finite beta equilibrium have yielded equivalent results between serial, one-processor and multi-processor parallel implementations. Linear and nonlinear tests are currently under way between the general geometry and circular geometry modules with a circular equilibrium which can be accommodated in both modules. Results from all of these tests will be reported, along with strategies for the global extension of both the circular and general geometry modules.

    Minnesota has the lowest overall coronary heart disease mortality rate in the United States. Yet disparities between men and women persist with regard to prevention, detection, and treatment. This has led to a gender gap not only in terms of care but also in survival rates. In an effort to better understand and close the gender gap, the Minneapolis Heart Institute, the Minneapolis Heart Institute Foundation, the University of Minnesota, and Mayo Clinic hosted a multidisciplinary Women's Heart Summit in April 2010. The goals of the summit were to stimulate dialogue and devise strategies to eliminate untimely deaths of women from heart disease. Summit participants were asked to contribute suggestions--called "Bold Ideas"--to address sex-based differences in the prevention, detection, and treatment of heart disease. Ideas were categorized according to three themes: educational programming, modifications to the health care system, and government involvement and funding. From these, several solutions emerged: 1) Involve obstetric/gynecologic physicians in providing heart-health education; 2) involve mid-level providers (midwives and other advanced practice women's health care providers) and other health professionals in women's heart health education, and 3) maximize the use of social media and online newsfeeds to raise awareness of heart disease in women. This article summarizes the discussion of the main ideas submitted by summit participants.

    Summit Station began its life at the summit of the Greenland Ice Sheet (72°N, 38°W, 3200 m.a.s.l.), as the drilling camp for the GISP2 ice core in 1989. Since then, the station has hosted both summer campaign science, and since 1997, year-round observations of atmospheric and cryospheric processes, both chemical and physical. After "experimental" winter seasons in 1997-98 and 2000-2002, the station has been continuously occupied since 2003. While most of the science activities at the station are supported by the US NSF Polar Division, the station also hosts many interagency and international investigations in physical glaciology, atmospheric chemistry, and other disciplines. Projects requiring access to the only high elevation observatory North of the Arctic circle providing clean air or snow for chemistry experiments will find Summit a unique and suitable location. In addition to investigator-driven projects, Summit hosts a cooperative NOAA-NSF Long Term Observatory (LTO) program committed to maintaining year-round measurements of key baseline variables of climate change at the site., The facility is operated by CH2M HILL Polar Services (CPS) with guidance from the Science Coordination Office (SCO), and the cooperation of the Government of Greenland. Facility support is primarily from NSF ARSL. Summit has historically served as a logistical hub for wider-ranging field studies in central Greenland and also stationary projects seeking a convenient location in the dry-snow zone. These functions conflict with the goal of reducing emissions at Summit in support of clean science. In recent years and into the future, projects without a need for the unique clean-snow / air characteristics will be increasingly directed to alternate locations in the dry-snow zone. These locations include a new logistical-hub to the north that will serve as the base of operations for projects not requiring a direct connection to the historical climate records of Summit , or locations

    The Mauna Kea summit region is largely comprised of cinder cones and lava flows that form the cap of the Mauna Kea Volcano. The cones and flows at the summit are part of the Laupahoehoe Volcanic series. The Laupa hoehoe volcanism occurred both during and after the late Pleistocene Makanaka glacial episode at the summit. In addition, a few Laupahoehoe cones have been glacially eroded as evidenced by oversteepened slopes, which suggests that they predate the Makanaka glacial period. Two notable examples of possible preglacial cones are Puu Waiau and Puu Poliahu. These two cones are also significantly altered, most likely by hydrothermal activity that has weakly cemented the materials on the cones. Well-crystalline sulfates (alunite and jarosite), phyllosilicates, and zeolites, have been found in samples collected from altered cones at the summit. In addition, palagonitic tephra, which have nanophase ferric oxide, allophane, and other poorly crystalline forms of weakly altered basaltic glass (i.e., no phyllosilicates), have been described at several locations on Mauna Kea. While several studies have discussed the occurrence of alteration products on Mauna Kea, the distribution of these materials exposed at the summit has not been extensively mapped. Hyperspectral imaging can provide information for identifying and mapping lithologic units containing alteration minerals, such as are found on Mauna Kea. The Airborne Visible Infrared Imaging Spectrometer (AVIRIS) is a hyperspectral imaging instrument that covers the wavelength range from about 0.4 to 2.5 micron in 224 bands, with a band spacing of 10 nm and average band width of 10 nm

    Since the construction of Dillon Reservoir, in Summit County, Colorado, in 1963, its drainage area has been the site of rapid urban development and the continued influence of historical mining. In an effort to assess changes in water quality within the drainage area, sediment cores were collected from Dillon Reservoir in 1997. The sediment cores were analyzed for pesticides, polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and trace elements. Pesticides, PCBs, and PAHs were used to determine the effects of urban development, and trace elements were used to identify mining contributions. Water-quality and streambed-sediment samples, collected at the mouth of three streams that drain into Dillon Reservoir, were analyzed for trace elements. Of the 14 pesticides and 3 PCBs for which the sediment samples were analyzed, only 2 pesticides were detected. Low amounts of dichloro-diphenyldichloroethylene (DDE) and dichloro-diphenyldichloroethane (DDD), metabolites of dichlorodiphenyltrichloroethane (DDT), were found at core depths of 5 centimeters and below 15 centimeters in a core collected near the dam. The longest core, which was collected near the dam, spanned the entire sedimentation history of the reservoir. Concentrations of total combustion PAH and the ratio of fluoranthene to pyrene in the core sample decreased with core depth and increased over time. This relation is likely due to growth in residential and tourist populations in the region. Comparisons between core samples gathered in each arm of the reservoir showed the highest PAH concentrations were found in the Tenmile Creek arm, the only arm that has an urban area on its shores, the town of Frisco. All PAH concentrations, except the pyrene concentration in one segment in the core near the dam and acenaphthylene concentrations in the tops of three cores taken in the reservoir arms, were below Canadian interim freshwater sediment-quality guidelines.

    1. Summit metabolism of lambs declined steadily from about 3·5 l. O2/kg.hr during the first day of life, to about 2·0 l. O2/kg.hr at 2 months of age. 2. The contributions of shivering and non-shivering thermogenesis to these changes were estimated by three independent methods; non-shivering thermogenesis was stimulated by catecholamines in a thermoneutral environment, shivering was suppressed by curariform drugs during summit metabolism, and an attempt was made to suppress non-shivering thermogenesis during summit metabolism by use of the sympatholytic drugs phentolamine and propranolol. Drugs were given by intravenous infusion during measurement of oxygen consumption in a closed circuit respiration chamber. 3. `Resting' metabolic rate of lambs during the first day of life was increased two to three-fold, from 1 l. O2/kg.hr, by either adrenaline or noradrenaline infused at 1-10 μg/kg.min. The increase declined with increasing age of lamb and was virtually absent by 3 weeks. The response to catecholamines appeared maximal at the dose levels used. 4. Muscular paralysis induced by suxamethonium or gallamine reduced summit metabolism by about 2 l. O2/kg.hr in all lambs examined within the first 2 months of life. The residual metabolic rate, and the metabolic response to catecholamines under thermoneutral conditions, declined with age in the same manner, and their magnitudes were similar. 5. Summit metabolism in lambs aged up to 2 months was depressed to varying degrees by the sympathetic inhibitors phentolamine, propranolol and hexamethonium. The depression with propranolol was greater, and the decline with age clearer, than with phentolamine. Hexamethonium and phentolamine depressed blood pressure, propranolol decreased heart rate and phentolamine and propranolol each suppressed shivering in some experiments. 6. In 1 day-old lambs estimates of non-shivering thermogenesis, by the various methods, ranged from 0·8 to 1·4 l. O2/kg.hr (mean 1·1 l. or 31% of summit

    Advances in technology show promise as tools to optimize functional mobility, independence, and participation in infants and children with motor disability due to brain injury. Although technologies are often used in adult rehabilitation, these have not been widely applied to rehabilitation of infants and children. In October 2015, the Academy of Pediatric Physical Therapy sponsored Research Summit IV, "Innovations in Technology for Children With Brain Insults: Maximizing Outcomes." The summit included pediatric physical therapist researchers, experts from other scientific fields, funding agencies, and consumers. Participants identified challenges in implementing technology in pediatric rehabilitation including accessibility, affordability, managing large data sets, and identifying relevant data elements. Participants identified 4 key areas for technology development: to determine (1) thresholds for learning, (2) appropriate transfer to independence, (3) optimal measurement of subtle changes, and (4) how to adapt to growth and changing abilities.

    The 2013 North American Agricultural Safety Summit, an unprecedented gathering of industry leaders and safety experts, was held September 25-27 in Minneapolis, MN. Hosted by the industry-led Agricultural Safety and Health Council of America (ASHCA), there were 250 attendees, 82 speakers, 76 abstracts with poster presentations, along with "best practices" videos, genius bars sessions, learning stations, exhibits, breakfast roundtable topics, and receptions. The event was a mix of knowledge, inspiration and networking to enable participants to influence the adoption of safety practices in their home/work settings. Given the agriculture industry's commitment to feed nine billion people, the projected world population by 2050, it is imperative that producers and agribusiness strive to do it safely, humanely and sustainably. Evaluation feedback was very positive, indicating ASHCA's original objectives for the Summit were achieved.

    In this video Bill Brinkman, Director of DOE's Office of Science, introduces the session, "Leading Perspectives in Energy Research," at the 2011 EFRC Summit and Forum. During the introduction of the senior representatives from both the public and private sector, Dr. Brinkman explained the motivation for creating the Energy Frontiers Research Centers program. The 2011 EFRC Summit and Forum brought together the EFRC community and science and policy leaders from universities, national laboratories, industry and government to discuss "Science for our Nation's Energy Future." In August 2009, the Office of Science established 46 Energy Frontier Research Centers. The EFRCs are collaborative research efforts intended to accelerate high-risk, high-reward fundamental research, the scientific basis for transformative energy technologies of the future. These Centers involve universities, national laboratories, nonprofit organizations, and for-profit firms, singly or in partnerships, selected by scientific peer review. They are funded at $2 to $5 million per year for a total planned DOE commitment of $777 million over the initial five-year award period, pending Congressional appropriations. These integrated, multi-investigator Centers are conducting fundamental research focusing on one or more of several “grand challenges” and use-inspired “basic research needs” recently identified in major strategic planning efforts by the scientific community. The purpose of the EFRCs is to integrate the talents and expertise of leading scientists in a setting designed to accelerate research that transforms the future of energy and the environment.

    1997-12-01

    FAO [UN Food and Agriculture Organization] does not stand alone in implementing and monitoring the Summit Plan of Action. Commitments 7.2 and 7.3 give responsibility to the UN's Administrative Committee on Coordination (ACC) for coordinating interagency follow-up and to the Economic and Social Committee (ECOSOC) for receiving progress reports from FAO and other agencies. The UN General Assembly in December 1996 welcomed the outcome of the Summit and received FAO's first report on it at its 1997 session. The ACC has launched interagency follow-up by establishing the ACC Network on Rural Development and Food Security, as proposed jointly by FAO and the International Fund for Agricultural Development (IFAD). More than 16 UN agencies have joined and the UN Secretary-General has welcomed the intention to involve civil society and the emphasis placed on country-level action in the two-tiered network. All FAO country representatives and UN resident coordinators have been asked to help in setting up interagency thematic groups on rural development and food security at the country level. FAO has introduced a website for the network within SD Dimensions (http://www.fao.org/waicent/faoinfo/sustdev). ECOSOC has welcomed the ACC's decision to include follow-up to the World Food Summit within the context of the integrated follow-up process of all major UN conferences and summits. With these decisions, the machinery has been set in motion for early and sustained support from both interagency and intergovernmental bodies to national efforts to implement the Plan of Action.

    Epithelial hyperplasia has been found to occur after photorefractive keratectomy in eyes treated with small (5 mm or less) ablation zone diameters with the Summit laser, but not with large zones (6 mm) with the VISX laser (Gauthier et al. 1995a). The aim of this study was to further investigate the effect of surgical parameters on epithelial hyperplasia by comparing eyes treated with the same zone diameter but two different lasers. We examined 11 subjects who had photorefractive keratectomy for myopia performed with 5 mm ablation zones with the Summit excimer laser in one eye and the VISX 20/20 laser in the fellow eye an average of 21 months previously. Epithelial thickness and corneal topography were measured. The mean epithelial thickness was not statistically different (p = 0.083) between the eyes treated with the Summit (66 +/- 12 microns) and VISX (60 +/- 14 microns) lasers. Postoperative corneal dioptric power showed a similar profile between the two eyes at the edge of the zone, with the VISX-treated corneas being more shallow centrally. There was a trend towards greater epithelial thickness with deeper ablations. This study supports the hypothesis that epithelial hyperplasia is dependent on ablation zone diameter and ablation depth.

    The Federation of Pediatric Organizations engaged members of the pediatric community in an 18-month process to envision the future of the workforce in pediatrics, culminating in a Visioning Summit on the Future of the Workforce in Pediatrics. This article documents the planning process and methods used. Four working groups were based on the 4 domains that are likely to affect the future workforce: Child Health Research and Training, Diversity and Inclusion, Gender and Generations, and Pediatric Training Along the Continuum. These groups identified the issues and trends and prioritized their recommendations. Before the summit, 5 key megatrends cutting across all domains were identified:1. Aligning Education to the Emerging Health Needs of Children and Families 2. Promoting Future Support for Research Training and for Child Health Research 3. Striving Toward Mastery Within the Profession 4. Aligning and Optimizing Pediatric Practice in a Changing Health Care Delivery System 5. Taking Advantage of the Changing Demographics and Expertise of the Pediatric Workforce At the Visioning Summit, we assembled members of each of the working groups, the Federation of Pediatric Organizations Board of Directors, and several invited guests to discuss the 5 megatrends and develop the vision, solutions, and actions for each megatrend. Based on this discussion, we offer 10 recommendations for the field of pediatrics and its leading organizations to consider taking action.

    The mass balance of a glacier reflects how the mass of the ice sheet changes over time, which reflects climate change and could affect sea level rise. The rate at which snow accumulates is essential for calculating the mass balance of the Greenland ice sheet. We examine the accumulation measured monthly from 2006 to 2011 at 121 stakes in a stepping line near Summit, Greenland. We investigate the temporal patterns in accumulation with a monthly resolution. We find that seasonally, September experiences the most accumulation. We also determine that there is no significant change in accumulation rates over the study period. We then examine the spatial patterns of accumulation in order to determine if the accumulation record from the stakes can be considered an accurate estimate for regional accumulation patterns. We find that the accumulation surface is very smooth at our sampling scale; there are no ridge or trough features that might cause unrepresentative data. However, the stake line experiences increased accumulation in the South, which may be a snowdrift caused by the structures of nearby Summit Camp. Considering the possibility of drift from Summit, the accumulation measurements near the southern end of the stake line cannot be used as a regional estimate for accumulation.

    The Greenland Ice Sheet (GIS) is a large and unique feature in the Arctic. Long-term changes in the mass balance of the ice sheet, precipitation, runoff, and ice discharge have been observed on the GIS, along with recent extreme events such as the exceptional warm period and associated melting in July 2012. Clouds are important modulators of the surface energy budget and transporters of moisture; thus clouds influence these observations. Few measurements of clouds had been made over the GIS until the spring of 2010 when the Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation at Summit (ICECAPS) atmospheric observatory began collecting data at Summit Station [72 N, 38 W, 3200 m]. ICECAPS observations of clouds and the atmosphere include those from an infrared spectrometer, lidar, radar, microwave radiometers, and radiosondes, among others. Brightness temperatures in cloud-sensitive microwindows from the ICECAPS infrared spectrometer, the Polar Atmospheric Emitted Radiance Interferometer (PAERI), and downwelling longwave fluxes are good indicators of cloud presence and cloud energy impact; thus, over time they are also good indicators of cloud variability. In this study, we examine these parameters to gain a more detailed understanding of the variability over Summit Station between spring 2010 and summer 2012, and how the variability might be connected to synoptic activity in the northern mid-latitudes. This information will be useful in evaluating model performance and in establishing a baseline for cloud temporal variability over the GIS.

    Toxicology and careers in toxicology, as well as many other scientific disciplines, are undergoing rapid and dramatic changes as new discoveries, technologies, and hazards advance at a blinding rate. There are new and ever increasing demands on toxicologists to keep pace with expanding global economies, highly fluid policy debates, and increasingly complex global threats to public health. These demands must be met with new paradigms for multidisciplinary, technologically complex, and collaborative approaches that require advanced and continuing education in toxicology and associated disciplines. This requires paradigm shifts in educational programs that support recruitment, development, and training of the modern toxicologist, as well as continued education and retraining of the midcareer professional to keep pace and sustain careers in industry, government, and academia. The Society of Toxicology convened the Toxicology Educational Summit to discuss the state of toxicology education and to strategically address educational needs and the sustained advancement of toxicology as a profession. The Summit focused on core issues of: building for the future of toxicology through educational programs; defining education and training needs; developing the "Total Toxicologist"; continued training and retraining toxicologists to sustain their careers; and, finally, supporting toxicology education and professional development. This report summarizes the outcomes of the Summit, presents examples of successful programs that advance toxicology education, and concludes with strategies that will insure the future of toxicology through advanced educational initiatives.

    Hydrothermal activity above Loihi submarine volcano was characterized by water column distributions of methane, pH and helium-3. It was found that the southern Loihi summit is almost covered with hydrothermal plumes, which have anomalously high concentrations of methane (maximum: 569 {times} 10{sup {minus}6} cm{sup 3} kg{sup {minus}}1) accompanied by high concentrations of helium-3 and low pH values (minimum: 7.18). The plumes consist of two layers: a shallow plume (about 200 m above the summit) and a deep plume (about 100 m above the summit), probably derived from different hydrothermal vents. The shallow and deep plumes showed different CH{sub 4}/{sup 3}He and CH{sub 4}/pH ratios with the same {sup 3}He/pH ratio, which implies that methane concentrations differ between the hydrothermal end members for the two plumes. The variation of methane between the end members is suggested to result from inter-vent inhomogeneity of bacterial activities that consume or produce methane within the vents. Comparison of the CH{sub 4}/{sup 3}He ratios of the two plumes with the previous data for Loihi and other submarine hydrothermal areas confirms that the Loihi hotspot has one to two orders of magnitude smaller CH{sub 4}/{sup 3}He value than those of the East Pacific Rise and the Galapagos spreading centers.

    There is a growing mandate from the public, payers, hospitals, and Centers for Medicare & Medicaid Services (CMS) to measure and improve emergency department (ED) performance. This creates a compelling need for a standard set of definitions about the measurement of ED operational performance. This Concepts article reports the consensus of a summit of emergency medicine experts tasked with the review, expansion, and update of key definitions and metrics for ED operations. Thirty-two emergency medicine leaders convened for the Second Performance Measures and Benchmarking Summit on February 24, 2010. Before arrival, attendees were provided with the original definitions published in 2006 and were surveyed about gaps and limitations in the original work. According to survey responses, a work plan to revise and update the definitions was developed. Published definitions from key stakeholders in emergency medicine and health care were reviewed and circulated. At the summit, attendees discussed and debated key terminology and metrics and work groups were created to draft the revised document. Workgroups communicated online and by teleconference to reach consensus. When possible, definitions were aligned with performance measures and definitions put forth by the CMS, the Emergency Nurses Association Consistent Metrics Document, and the National Quality Forum. The results of this work are presented as a reference document. PMID:21067846

  11. SR proteins Asf/SF2 and 9G8 interact to activate enhancer-dependent intron D splicing of bovine growth hormone pre-mRNA in vitro.

    The alternative splicing of the last intron (intron D) of bovine growth hormone (bGH) pre-mRNA requires a down-stream exonic splicing enhancer (FP/ESE). The presence of at least one SR protein has been shown to be essential for FP/ESE function and splicing of intron D in in vitro splicing assays. However, in vitro reconstitution of splicing using individual purified SR proteins may not accurately reflect the true complexity of alternative splicing in an intact nucleus, where multiple SR proteins in varying amounts are likely to be available simultaneously. Here, a panel of recombinant baculovirus-expressed SR proteins was produced and tested for the ability to activate FP/ESE-dependent splicing. Individual recombinant SR proteins differed significantly in their activity in promoting intron D splicing. Among the recombinant SR proteins tested, SRp55 was the most active, SC35 showed very little activity, and ASF/SF2 and 9G8 individually had intermediate activity. At least one SR protein (ASF/SF2) bound to the FP/ESE with characteristics of a cooperative interaction. Most interestingly, low concentrations of ASF/SF2 and 9G8 acted synergistically to activate intron D splicing. This was due in part to synergistic binding to the FP/ESE. Splicing of bGH intron D is inherently complex, and is likely controlled by an interaction of the FP/ESE with several trans-acting protein factors acting both independently and cooperatively. This level of complexity may be required for precise control of alternative splicing by an exon sequence, which simultaneously is constrained to maintain translational integrity of the mature mRNA.

  12. A Structural and Paleomagnetic Analysis of the Basalts of Summit Creek, central Cascades, Washington

    This study is a detailed analysis of the structural geology and paleomagnetism of the Basalts of Summit Creek. Located southeast of Mount Rainier, this section of layered basaltic flows formed during the Eocene Epoch (55 to 45 Ma). During the Eocene, this region underwent a time of unique volcanism that has shaped the modern landscape of the Pacific Northwest. Over the course of the available field season, five excursions were taken into the field to conduct structural mapping and paleomagnetic core drilling. Although exposure is limited by vegetation, nineteen sites were mapped and ten of those were drilled for cores. Cores were analyzed using alternating field demagnetization and thermal demagnetization. Mapping data was integrated into a preliminary structural map of the section. This study attempts to provide a greater understanding of the emplacement and deformation of the Basalts of the Summit Creek and any possible relationship with the Crescent Basalts located in the Olympic Peninsula of Washington state. Once paleomagnetic directions were corrected for core orientation and bedding tilt, none of the flows yielded orientations consistent enough to provide reliable magnetic directions for the section. This scatter is believed to be due, in part, to hydrothermal alteration that has subsequently influenced the Basalts of the Summit Creek. The scattered magnetic orientations are quite similar to those observed in the Crescent Basalts. This is does not demonstrate a definite connection between the two chemically similar Eocene volcanic sequences, but it does provide another similarity on the growing list. The lava flows along the north, middle, and south of the area and, with a few exceptions, have a northeast strike and a northwest dip. Along the middle transect of the section, nearest to Pony Creek and Carleton Ridge, bedding orientation has greater variability and suggests that there may still be unidentified structures that are influencing the area.

    Reactive halogens, and in particular bromine oxide (BrO), have frequently been observed in regions with large halide reservoirs, for example during bromine catalyzed coastal polar ozone depletion events. Much less is known about the presence and impact of reactive halogens in areas without obvious halide reservoirs, such as the polar ice sheets or continental snow. We report the first LP-DOAS measurements of BrO at Summit research station in the center of the Greenland ice sheet at an altitude of 3200 m. BrO mixing ratios in May 2007 and June 2008 were typically between 1-3 pmol mol-1, with maxima of up to 5 pmol mol-1. These measurements unequivocally show that halogen chemistry is occurring in the remote Arctic, far from known bromine reservoirs, such as the ocean. During periods when FLEXPART retroplumes show that airmasses resided on the Greenland ice sheet for 3 or more days, BrO exhibits a clear diurnal variation, with peak mixing ratios of up to 3 pmol mol-1 in the morning and at night. The diurnal cycle of BrO can be explained by a changing boundary layer height combined with photochemical formation of reactive bromine driven by solar radiation at the snow surface. The shallow stable boundary in the morning and night leads to an accumulation of BrO at the surface, leading to elevated BrO despite the expected smaller release from the snowpack during these times of low solar radiation. During the day when photolytic formation of reactive bromine is expected to be highest, efficient mixing into a deeper neutral boundary layer leads to lower BrO mixing ratios than during mornings and nights. The extended period of contact with the Greenland snowpack combined with the diurnal profile of BrO, modulated by boundary layer height, suggests that photochemistry in the snow is a significant source of BrO measured at Summit during the 2008 experiment.

The third approach requires individual nodes within the value chain to maintain electronic records for its own data and make them available for querying during a traceback for outbreak investigation. The major advantage of this approach is the protection of confidential information and the potential for quicker access during a trace. However, the primary disadvantage of this approach is the need for greater computational power and a more complex mechanism to linking the value chain through the data. As next steps, a subgroup will work on clarifying the approach to meeting the goals of traceability, better defining critical tracking events, and articulating the strategy and return on investment from a regulatory and industry perspective. This will result in improved alignment of on-going traceability pilots and initiatives as well as a more actionable guidance document for public review. PMID:23216103

During the introduction of the senior representatives from both the public and private sector, Dr. Brinkman explained the motivation for creating the Energy Frontiers Research Centers program. The 2011 EFRC Summit and Forum brought together the EFRC community and science and policy leaders from universities, national laboratories, industry and government to discuss "Science for our Nation's Energy Future." In August 2009, the Office of Science established 46 Energy Frontier Research Centers. The EFRCs are collaborative research efforts intended to accelerate high-risk, high-reward fundamental research, the scientific basis for transformative energy technologies of the future. These Centers involve universities, national laboratories, nonprofit organizations, and for-profit firms, singly or in partnerships, selected by scientific peer review. They are funded at $2 to $5 million per year for a total planned DOE commitment of $777 million over the initial five-year award period, pending Congressional appropriations. These integrated, multi-investigator Centers are conducting fundamental research focusing on one or more of several “grand challenges” and use-inspired “basic research needs” recently identified in major strategic planning efforts by the scientific community. The purpose of the EFRCs is to integrate the talents and expertise of leading scientists in a setting designed to accelerate research that transforms the future of energy and the environment.

  19. The preservation of long-range transported nitrate in snow at Summit, Greenland (Invited)

    NASA Astrophysics Data System (ADS)

    Hastings, M. G.

    2013-12-01

    Nitrate is one of the major anions found in polar and alpine snow, both today and in the past. Deposition of nitrate to snow surfaces results from reactions of nitrogen oxides (NOx) with oxidants in the atmosphere, resulting in the production of HNO3 that is incorporated into precipitation or reacts on the surface of particles. Several factors motivate studying nitrate concentration in ice cores including reconstructing past levels of NOx, tropospheric oxidant concentrations and natural variability in NOx sources. The link between the atmospheric concentration of NOx and nitrate concentration in ice core records is problematic because post-depositional processing, such as photolysis and evaporation, can impact the concentration of nitrate in snow. Recent work has shown that the isotopic ratios of nitrate (15N/14N, 18O/16O, 17O/16O) can be a powerful tool for tracing post-depositional loss of nitrate from surface snow. The isotopic composition of nitrate has been shown to contain information about the source of the nitrate (i.e, NOx sources) and the oxidation processes that convert NOx to nitrate in the atmosphere prior to deposition. Results from a number of studies at Summit, Greenland reveal limited loss of nitrate from surface snow during highly photoactive periods, and the oxygen isotopic signatures in snow nitrate appear to be representative of atmospheric deposition of nitrate from outside of Summit. Higher than expected oxygen isotope ratios (18O/16O, 17O/16O) found in Summit summertime nitrate were expected to be dependent upon local photochemistry in which nitrate in the snow is photolyzed to NOx that is then oxidized above the snow by BrO to reform nitrate (i.e., BrONO2). However, the oxygen isotopic composition of nitrate collected at high time resolution in surface snow does not show any link to local gas phase concentrations of a number of species, including BrO. Furthermore, the combination of nitrogen and oxygen isotope data reveals interesting

    With the current warming trend of the Earth's climate, the Greenland Ice Sheet (GIS) has been melting on its fringes and experiencing mass loss. However, the mass balance of the GIS as a whole is not well understood due to a deficiency of knowledge of the interior. Central to understanding this mass balance is precipitation, of which non-satellite derived observations over the central GIS are sparse. Here a conditional snowfall retrieval for the ground-based Precipitation Occurrence Sensor System (POSS), which is part of the Integrated Characterization of Energy, Clouds, Atmospheric state and Precipitation at Summit (ICECAPS) project in Greenland, is described. The conditional restraints for the POSS retrieval are based on qualitative ice particle habit information derived from relating periodic on-site ice crystal images to ranges of cloud base temperature derived from instantaneous lidar and interpolated radiosonde measurements. The snowfall from this habit-dependent retrieval is compared to various fixed-habit retrievals for the POSS, as well as other coinciding snowfall measurements taken at Summit by a vertical-pointing Ka-band cloud radar. Providing a broader perspective, this radar-based precipitation data is analyzed alongside weekly measurements from an accumulation forest, that includes a 10x10 grid of bamboo stakes that are used to measure the height change in the snow surface. In addition to snowfall, surface height changes include contributions from deposition, sublimation, melting, drifting, and compaction that must be accounted for. Using these three perspectives on snowfall, the annual cycle of precipitation at Summit, Greenland over the past three years is examined.

  1. Reconstructing thermal properties of firn at Summit, Greenland from a temperature profile

    NASA Astrophysics Data System (ADS)

    Giese, A. L.; Hawley, R. L.

    2013-12-01

    Thermodynamic properties of firn are important factors when considering energy balance and temperature-dependent physical processes in the near-surface of glaciers. Of particular interest is thermal diffusivity, which can take a range of values and which governs both the temperature gradient and its evolution through time. Given that temperature is a well-established driver of firn densification, a better understanding of heat transfer will permit greater accuracy in the compaction models essential for interpreting inter-annual and seasonal ice surface elevation changes detected by airborne and satellite altimetry. Due to its dependence on microstructure, diffusivity can vary significantly by location. Rather than directly measuring diffusivity or one of its proxies (e.g. density, hardness, shear strength), this study inverts the heat equation to reconstruct diffusivity values. This is a less logistically-intensive approach which circumvents many of the challenges associated with imperfect proxies and snow metamorphism during measurement. Hourly records (May 2004 - July 2008) from 8 thermistors placed in the top 10 m at Summit, Greenland provide temperature values for Summit's firn, which is broadly representative of firn across the ice sheet's dry snow zone. In this study, we use both physical analysis and a finite-difference numerical model to determine a diffusivity magnitude and gradient; we find that diffusivity of Summit firn falls in the lower end of the range expected from local density and temperature conditions alone (i.e. 15 - 36 m^2/a for firn at -30C). Further, we assess the utility of our modeling approach, explore the validity of assuming bulk conductive heat transfer when modeling temperature changes in non-homogeneous firn, and investigate the implications of a low-end diffusivity value for surface compaction modeling in Greenland.

    Quantifying surface elevation change is essential for ice sheet mass balance estimates. We assessed surface elevation and elevation change of the Greenland Ice Sheet at a range of spatial scales using six years of monthly GPS surveys conducted near Summit between 8/2007 and 3/2013. The ~11 km route consists of 15 transects that run parallel and orthogonal to IceSat's groundtrack 412 and includes 121 repeat locations spatially distributed along the route (Figure 1). Horizontal velocities and velocity gradients derived from base station and transect positions agree closely with previous studies. At the survey scale, no significant linear elevation trend is evident over the study period. However, local- and transect-scale time series revealed significant elevation increases of 1--2 cm per year in the central and southern regions of the survey that spatially and temporally may correlate with wind transport events from Summit station. This finding illustrates how sample scale (e.g., density, location and extent) affects surface elevation estimates critical to remote sensing validation and mass balance estimation. Spectral time series analysis showed that the expected annual elevation cycle was dwarfed by a two-year periodicity that dominated nearly all time series. The elevation maximum of Winter 2012-2013 fell short of the expected elevation peak, possibly due to accelerated compaction forced by high temperatures in the preceding Summer of 2012. We also highlight spatial comparisons with elevation products from three NASA altimeters, including the Airborne Topographic Mapper (ATM), the Land, Vegetation, and Ice Sensor (LVIS), and the Multiple Altimeter Beam Experiment Lidar (MABEL). This unique long-term GPS dataset is valuable for assessing ice sheet elevation change at a range of spatial-temporal scales, and for validating remote sensing products. With continued effort this survey will provide invaluable ground-based observations linking ICESat, IceBridge and ICESat

    Radiosondes are balloon-borne meteorological sensors used to acquire profiles of temperature and humidity. Radiosonde data are essential inputs for numerical weather prediction models and are used for climate research, particularly in the creation of reanalysis products. However, radiosonde programs are costly to maintain, in particular in the remote regions of the Arctic (e.g., $440,000/yr at Summit, Greenland), where only 40 of approximately 1000 routine global launches are made. The climate of this data-sparse region is poorly understood and forecast data assimilation procedures are designed for global applications. Thus, observations may be rejected from the data assimilation because they are too far from the model expectations. For the most cost-efficient deployment of resources and to improve forecasting methods, analyses of the effectiveness of individual radiosonde programs are necessary. Here, we evaluate how radiosondes launched twice daily (0 and 12 UTC) from Summit Station, Greenland, (72.58⁰N, 38.48⁰W, 3210 masl) influence the European Centre for Medium Range Weather Forecasting (ECMWF) operational forecasts from June 2013 through May of 2015. A statistical analysis is conducted to determine the impact of the observations on the forecast model and the meteorological regimes that the model fails to reproduce are identified. Assimilation rates in the inversion layer are lower than any other part of the troposphere. Above the inversion, assimilation rates range from 85%-100%, 60%-98%, and > 99% for temperature, humidity, and wind, respectively. The lowest assimilation rates are found near the surface, possibly associated with biases in the representation of the temperature inversion by the ECMWF model at Summit. Consequently, assimilation rates are lower near the surface during winter when strong temperature inversions are frequently observed. Our findings benefit the scientific community who uses this information for climatological analysis of the

    As a major sink of atmospheric nitrogen oxides (NOx = NO + NO2), nitrate (NO3-) in polar snow can reflect the long-range transport of NOx and related species (e.g., peroxyacetyl nitrate). On the other hand, because NO3- in snow can be photolyzed, potentially producing gas phase NOx locally, NO3- in snow (and thus, ice) may reflect local processes. Here we investigate the relationship between local atmospheric composition at Summit, Greenland (72°35'N, 38°25'W) and the isotopic composition of NO3- to determine the degree to which local processes influence atmospheric and snow NO3-. Based on snow and atmospheric observations during May-June 2010 and 2011, we find no connection between the local atmospheric concentrations of a suite of gases (BrO, NO, NOy, HNO3, and nitrite (NO2-)) and the NO3- isotopic composition or concentration in snow. This suggests that (1) the snow NO3- at Summit is primarily derived from long-range transport and (2) this NO3- is largely preserved in the snow. Additionally, three isotopically distinct NO3- sources were found to be contributing to the NO3- in the snow at Summit during both 2010 and 2011. Through the complete isotopic composition of NO3-, we suggest that these sources are local anthropogenic particulate NO3- from station activities (δ15N = 16‰, Δ17O = 4‰, and δ18O = 23‰), NO3- formed from midlatitude NOx (δ15N = -10‰, Δ17O = 29‰, δ18O = 78‰) and a NO3- source that is possibly influenced by or derived from stratospheric ozone NO3- (δ15N = 5‰, Δ17O = 39‰, δ18O = 100‰).

    Prior to the summit, there was general concern that the proposed expansion of NATO would prevent a successful summit and prevent agreement on any measures leading to the ratification of START II. The Duma has held up START II ratification for a number of reasons, but basically the Russians felt that START II was an inequitable agreement that would force them into a major, expensive buildup that they could not afford. There were also serious concerns in the Duma about US intentions in the area of ballistic missile defenses, which would affect their willingness to enter into substantial reductions. There are some very serious questions that remain, and it`s not even clear in some instances what was and wasn`t agreed to at the summit. With regard to NATO expansion, it was formally stated that the two sides disagreed on the desirability and acceptability of expansion. Yeltsin, however, accepted that he, in any case, could not stop the expansion process. He sought to get some amelioration for the problems that it would cause in Russian eyes. He did not get a formal charter between Russia and NATO outlining the limits of expansion and Russian rights, but rather a commitment to a document that was intended to minimize the potential consequences of disagreement. This document would seek, to some extent, to compensate Russian concerns. However, it was specifically indicated that it would not be a formal treaty but rather a heads-of-government document constituting a political commitment. This document does not exist, and it may not be that easy to formalize it between Russia and NATO. The Duma will be very disappointed in this outcome with regard to NATO expansion.

  8. Validation of MODIS Terra and Aqua Ice Surface Temperatures at Summit, Greenland

    Ice-surface temperature (IST) is used in many studies, for example for validation of model output and for detection of leads and thin ice in sea ice. The MODerate-resolution Imaging Spectroradiometer (MODIS) instruments on the Terra and Aqua satellites are useful for mapping IST of sea ice and the Greenland ice sheet (Hall et al., 2012), and validation of the ISTs derived from MODIS has been an ongoing effort (e.g., Koenig & Hall, 2010; Shuman et al., 2014). Recent results call into question the calibration of the MODIS-derived ISTs at very cold temperatures that are characteristic of the Greenland ice sheet high interior during winter (Shuman et al., 2014). In the present work, we investigate the calibration of MODIS IR bands 31 (10.780 - 11.280 µm) and 32 (11.770 - 12.270 µm) under very cold conditions. MODIS IR bands are calibrated using a quadratic algorithm. In Collection 6 (C6), the offset and nonlinear calibration coefficients are computed from data collected during the blackbody cool-down vs the warm-up data used in Collection 5 (C5). To improve the calibration accuracy for low-temperature scenes, the offset terms are set to 0. In general, Aqua MODIS bands 31 and 32 perform better than Terra MODIS bands 31 and 32. One of the reasons is that the Aqua bands have a lower saturation temperature (~340 K) than the Terra (~380 K) bands, and lower saturation or smaller dynamic range means better resolution. As compared to ~2-m NOAA air temperatures (TA) at Summit, Greenland, Shuman et al. (2014) show a small (~0.5°C) offset in Terra MODIS-derived IST vs TA near 0°C, and an increasingly larger offset (up to ~5°C) as TA drops to -60°C. To investigate this further, we compare Terra and Aqua C5 and C6 ISTs with TA data from Summit. This work will document the calibration of bands 31 and 32 at very low temperatures in C5 and C6.

    The Southern Patagonian Andes are known among mountain climbers for a meteorological phenomenon that occurs there but is unknown in many other mountain areas. The phenomenon is the buildup of rime ice in large bulbous or mushroom-shaped accretions on the windward side of projecting mountain summits, ridges and exposed near-vertical rock faces. These "ice mushrooms" have never been investigated scientifically. This talk will introduce the audience to ice mushrooms, describe where they are found, consider the meteorological factors leading to their formation, and illustrate how they are negotiated by mountain climbers using photographs and descriptions from Southern Patagonia.

    Concentrations of bromine oxide (BrO) >0.5 pptv have been detected regularly above the snowpack at Summit, Greenland [72°35'N, 38°25'W] during the spring and early summer. BrO often shows a diurnal cycle, with concentrations reaching as high as 10 pptv shortly after solar noon, although more typically found to be between 0.5 - 3.0 pptv. Our goal is to investigate the influence of BrO on the formation of nitrate (i.e. via BrONO2) based upon the oxygen isotopic composition of atmospheric and snow nitrate. Increased understanding of local nitrate post-depositional processing compared to transported nitrate will improve our ability to interpret nitrate in snow and ice core records. Deposition of nitrate results from reactions of NOx (NO and NO2) with oxidants in the atmosphere. The major oxidants in tropospheric nitrate formation, e.g. ozone (O3) and hydroxyl radical (OH), have distinctive isotopic compositions such that their relative contribution to NOx oxidation can be quantified based on Δ17O (Δ17O = δ17O - .52δ18O) of nitrate. In particular, O3 has a unique "mass independent fractionation" signature with Δ17O = 25-35% (per mil); BrO, formed from Br reacting with O3, is expected to carry a Δ17O = 30-42% (Morin et al., ACP, 2007); while OH has a Δ17O of 0%. Models of local photochemical post-depositional processing of NO3- utilizing the Δ17O of nitrate at Summit, Greenland cannot fully explain observed values (Kunasek et al., JGR, 2008; Jarvis et al., GRL, 2008). These O-D models do not include bromine chemistry. In a campaign consisting of two springtime (May-June) field seasons at Summit, Greenland, atmospheric and surface snow measurements were made to quantify the effect of bromine on the formation of atmospheric nitrate. Further, we look to use Δ17O of NO3- to investigate the influence of BrO on locally processed nitrate versus nitrate transported to Summit. Gas phase BrO, NO, NOy and soluble Br, NO3-, and NO2- were measured concurrently. In addition

    In the excited vibronic states of naphthalene, there exist various interesting interactions such as intramolecular vibrational energy redistribution (IVR), intersystem crossing (ISC), and internal conversion (IC). More than thirty yeas ago, Beck et al. showed that IVR became remarkable when the excess energy exceeded about 2000 cm-1^, ^a. In the present study, we observe Doppler-free two-photon absorption spectra of A^1B1u ← X^1A_g 8^1_04^1_0 band of naphthalene around 34281 cm-1. The excess energy is 2261 cm-1, which is just above the threshold of IVR. Thus we expect this band is suitable to analyze the dynamics in the excited vibronic states. In our experiment, the spectral resolution is about 100 kHz, and rovibronic lines are well-resolved. To decide the transition frequencies, frequency shifts, and spectral linewidths with high accuracy and precision, we employed the comb-referenced Doppler-free two-photon absorption spectroscopic system^b. We proceed to assign the rovibronic lines in ^qQ transition, and to determine molecular constants in the excited vibronic state. ^a S. M. Beck, J. B. Hopkins, D. E. Powers, and R. E. Smalley, J.

    The summit magma storage reservoir of Kīlauea Volcano is one of the most important components of the magmatic plumbing system of this frequently active basaltic shield-building volcano. Here we use new high-precision Pb isotopic analyses of Kīlauea summit lavas—from 1959 to the active Halema‘uma‘u lava lake—to infer the number, size, and interconnectedness of magma bodies within the volcano's summit reservoir. From 1971 to 1982, the 206Pb/204Pb ratios of the lavas define two separate magma mixing trends that correlate with differences in vent location and/or pre-eruptive magma temperature. These relationships, which contrast with a single magma mixing trend for lavas from 1959 to 1968, indicate that Kīlauea summit eruptions since at least 1971 were supplied from two distinct magma bodies. The locations of these magma bodies are inferred to coincide with two major deformation centers identified by geodetic monitoring of the volcano's summit region: (1) the main locus of the summit reservoir ∼2–4 km below the southern rim of Kīlauea Caldera and (2) a shallower magma body <2 km below the eastern rim of Halema‘uma‘u pit crater. Residence time modeling suggests that the total volume of magma within Kīlauea's summit reservoir during the late 20th century (1959–1982) was exceedingly small (∼0.1–0.5 km3). Voluminous Kīlauea eruptions, such as the ongoing, 32-yr old Pu‘u ‘Ō‘ō rift eruption (>4 km3 of lava erupted), must therefore be sustained by a nearly continuous supply of new melt from the mantle. The model results show that a minimum of four compositionally distinct, mantle-derived magma batches were delivered to the volcano (at least three directly to the summit reservoir) since 1959. These melt inputs correlate with the initiation of energetic (1959 Kīlauea Iki) and/or sustained (1969–1974 Mauna Ulu, 1983-present Pu‘u ‘Ō‘ō and 2008-present Halema‘uma‘u) eruptions.

    The first Organ Banking Summit was convened from Feb. 27 - March 1, 2015 in Palo Alto, CA, with events at Stanford University, NASA Research Park, and Lawrence Berkeley National Labs. Experts at the summit outlined the potential public health impact of organ banking, discussed the major remaining scientific challenges that need to be overcome in order to bank organs, and identified key opportunities to accelerate progress toward this goal. Many areas of public health could be revolutionized by the banking of organs and other complex tissues, including transplantation, oncofertility, tissue engineering, trauma medicine and emergency preparedness, basic biomedical research and drug discovery - and even space travel. Key remaining scientific sub-challenges were discussed including ice nucleation and growth, cryoprotectant and osmotic toxicities, chilling injury, thermo-mechanical stress, the need for rapid and uniform rewarming, and ischemia/reperfusion injury. A variety of opportunities to overcome these challenge areas were discussed, i.e. preconditioning for enhanced stress tolerance, nanoparticle rewarming, cyroprotectant screening strategies, and the use of cryoprotectant cocktails including ice binding agents.

    An evolving temperature record from the Greenland Summit Station, at approximately 3216 m in elevation, has documented unusual periods of near and above freezing air temperatures in July 2012. Since August 2005, data has been collected from well-calibrated and actively-ventilated temperature sensors at a NOAA-ESRL climate observatory. Comparison of these data from a nominal 2 m height above the ice sheet surface over the past seven summers reveals several periods of unusual warmth at the highest elevations of the ice sheet in 2012. Detailed analysis of the available data indicates that temperatures rose to or above freezing for almost 6.5 hours on July 11 at Summit Station. A maximum air temperature of 1 degree C was recorded repeatedly in the 1-minute averages during this period. NOAA's data also indicated brief periods at or above zero on July 12th and 29th as well. These anomalously warm air-temperature periods can now be compared and contrasted with equivalent-quality data from earlier records (automatic weather stations began operating in May 1987 during the GISP2 project) and used to calibrate indications of warm surface temperatures derived from multi-decadal satellite passive microwave and infrared sensors.

    Eric Issacs, Director of DOE's Argonne National Laboratory, discussed the role of the EFRC Program and National Laboratories in developing game-changing energy technologies in the EFRC Summit session titled "Leading Perspectives in Energy Research." The 2011 EFRC Summit and Forum brought together the EFRC community and science and policy leaders from universities, national laboratories, industry and government to discuss "Science for our Nation's Energy Future." In August 2009, the Office of Science established 46 Energy Frontier Research Centers. The EFRCs are collaborative research efforts intended to accelerate high-risk, high-reward fundamental research, the scientific basis for transformative energy technologies of the future. These Centers involve universities, national laboratories, nonprofit organizations, and for-profit firms, singly or in partnerships, selected by scientific peer review. They are funded at $2 to $5 million per year for a total planned DOE commitment of $777 million over the initial five-year award period, pending Congressional appropriations. These integrated, multi-investigator Centers are conducting fundamental research focusing on one or more of several “grand challenges” and use-inspired “basic research needs” recently identified in major strategic planning efforts by the scientific community. The purpose of the EFRCs is to integrate the talents and expertise of leading scientists in a setting designed to accelerate research that transforms the future of energy and the environment.

    The 2008 explosion that started a new eruption at the summit of Kīlauea Volcano, Hawai'i, was not preceded by a dramatic increase in earthquakes nor inflation, but was associated with increases in SO2 emissions and seismic tremor. Here we perform shear wave splitting analysis on local earthquakes spanning the onset of the eruption. Shear wave splitting measures seismic anisotropy and is traditionally used to infer changes in crustal stress over time. We show that shear wave splitting may also vary due to changes in volcanic degassing. The orientation of fast shear waves at Kīlauea is usually controlled by structure, but in 2008 showed changes with increased SO2 emissions preceding the start of the summit eruption. This interpretation for changing anisotropy is supported by corresponding decreases in Vp/Vs ratio. Our result demonstrates a novel method for detecting changes in gas flux using seismic observations and provides a new tool for monitoring under-instrumented volcanoes.

    A dearth of high-spatial and temporal resolution measurements of atmospheric state variables in the Arctic directly inhibits scientific understanding of radiative and precipitation impacts on the changing surface environment. More reliable and frequent measurements are needed to better understand Arctic weather processes and constrain model predictions. To partially address the lack of Artic observations, a new autonomous Raman lidar system, which will measure water vapor mixing ratio, temperature, extinction, and cloud phase profiles through the troposphere, is designed for deployment to Summit Camp, Greenland (72° 36' N, 38° 25' W, 3250 [m]). This high-altitude Arctic field site has co-located ancillary equipment such as a Doppler millimeter cloud radar, microwave radiometers, depolarization lidars, ceiliometer, an infrared interferometer and twice-daily radiosondes. The current suite of instruments allows for a near comprehensive picture of the atmospheric state above Summit but increased spatial and temporal resolution of water vapor and temperature will reveal detailed microphysical information. A system description will be provided with an emphasis on the Monte Carlo safety analysis done to ensure eye safety in all relevant weather conditions.

    In 1975, 3.2 km of Summit Creek, Idaho were fenced by the Bureau of Land Management to exclude livestock from the riparian area. Six stream sections were electrofished in 1979 to determine differences in trout abundance, size, and growth between grazed and ungrazed stream sections. Electrofishing stations were paired by habitat type. There were more trout in ungrazed sections than in grazed sections in all three habitat types sampled. With one exception, there were more catachable-sized (200 mm long or longer) rainbow trout (Salmo gairdneri) and brook trout (Salvelinus fontinalis) in the ungrazed area than in the grazed area. There was also evidence that the average size of the fish was less in grazed sections. Fish population data were not collected prior to fencing; therefore, it cannot be firmly concluded that the trout population increased within the livestock enclosure as a result of fencing the riparian area. However, the combined results of previous trout habitat improvements documented for Summit Creek, as a result of the fencing, and this study support the conclusion that trout prefer stream areas in ungrazed habitat over grazed habitat.

    The first Organ Banking Summit was convened from Feb. 27 - March 1, 2015 in Palo Alto, CA, with events at Stanford University, NASA Research Park, and Lawrence Berkeley National Labs. Experts at the summit outlined the potential public health impact of organ banking, discussed the major remaining scientific challenges that need to be overcome in order to bank organs, and identified key opportunities to accelerate progress toward this goal. Many areas of public health could be revolutionized by the banking of organs and other complex tissues, including transplantation, oncofertility, tissue engineering, trauma medicine and emergency preparedness, basic biomedical research and drug discovery - and even space travel. Key remaining scientific sub-challenges were discussed including ice nucleation and growth, cryoprotectant and osmotic toxicities, chilling injury, thermo-mechanical stress, the need for rapid and uniform rewarming, and ischemia/reperfusion injury. A variety of opportunities to overcome these challenge areas were discussed, i.e. preconditioning for enhanced stress tolerance, nanoparticle rewarming, cyroprotectant screening strategies, and the use of cryoprotectant cocktails including ice binding agents.

    On 2-3 June 2012, the University of Tromsoe hosted a conference about the cultural and scientific history of the transits of Venus. The conference took place in Tromsoe for two very specific reasons. First and foremost, the last transit of Venus of this century lent itself to be observed on the disc of the Midnight Sun in this part of Europe during the night of 5 to 6 June 2012. Second, several Venus transit expeditions in this region were central in the global enterprise of measuring the scale of the solar system in the eighteenth century. The site of the conference was the Nordnorsk Vitensenter (Science Centre of Northern Norway), which is located at the campus of the University of Tromsoe. After the conference, participants were invited to either stay in Tromsoe until the midnight of 5-6 June, or take part in a Venus transit voyage in Finnmark, during which the historical sites Vardoe, Hammerfest, and the North Cape were to be visited. The post-conference program culminated with the participants observing the transit of Venus in or near Tromsoe, Vardoe and even from a plane near Alta. These Proceedings contain a selection of the lectures delivered on 2-3 June 2012, and also a narrative description of the transit viewing from Tromsoe, Vardoe and Alta. The title of the book, Meeting Venus, refers the title of a play by the Hungarian film director, screenwriter and opera director Istvan Szabo (1938-). The autobiographical movie Meeting Venus (1991) directed by him is based on his experience directing Tannhauser at the Paris Opera in 1984. The movie brings the story of an imaginary international opera company that encounters a never ending series of difficulties and pitfalls that symbolise the challenges of any multicultural and international endeavour. As is evident from the many papers presented in this book, Meeting Venus not only contains the epic tales of the transits of the seventeenth, eighteenth and nineteenth centuries, it also covers the conference

    Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life. In a global scenario where hunger and obesity affect millions of people, public actions have been developed towards Food and Nutrition Security (FNS). In 1996 during the World Food Summit, 186 countries signed the Rome Declaration, committing themselves to assess and address Food and Nutrition Insecurity. In this exploratory study, we compile secondary internet data using keywords in four languages to map the global distribution, among signatories, of FNS public initiatives and assess their association with key national-level socioeconomic indicators. As a result, we found FNS public policies in 123 countries, reports on the state of FNS in 139 countries, and the presence of both in 114 countries (61%). The proportion of countries with any type of, as well as with specific, FNS policy or diagnostic was higher in least developed countries. There was a statistically significant association between these proportions and selected national-level socioeconomic variables. The results are discussed along with population vulnerability, international cooperation mechanisms and political discourse and how these factors impact the existence of FNS public actions.

    Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life. In a global scenario where hunger and obesity affect millions of people, public actions have been developed towards Food and Nutrition Security (FNS). In 1996 during the World Food Summit, 186 countries signed the Rome Declaration, committing themselves to assess and address Food and Nutrition Insecurity. In this exploratory study, we compile secondary internet data using keywords in four languages to map the global distribution, among signatories, of FNS public initiatives and assess their association with key national-level socioeconomic indicators. As a result, we found FNS public policies in 123 countries, reports on the state of FNS in 139 countries, and the presence of both in 114 countries (61%). The proportion of countries with any type of, as well as with specific, FNS policy or diagnostic was higher in least developed countries. There was a statistically significant association between these proportions and selected national-level socioeconomic variables. The results are discussed along with population vulnerability, international cooperation mechanisms and political discourse and how these factors impact the existence of FNS public actions.

    Colima Volcano, located in the West of the Volcanic Mexican Belt, has shown a new cycle of explosive activity beginning May 30 1999, and reaching its maximum in March and April of 2005. This year the explosive activity increased gradually, having the largest event on May 23, when a new dome was created. Hours later this dome was destroyed by a strong explosion, forming an ash column 5.6 km high with subsequent pyroclastic flows that reached a distance of 4.2 km flowing along the ravines of the South sector. On May 30 the most intense explosion in 1999 occurred, when the plume reached heights in excess of 4.4 km above the crater, and piroclastic flows were created. On the same year in July two explosive events occurred of characteristics similar to those in May. These constant explosions caused continuos morphological changes in the summit, the most significant being the collapse of the North and South walls of the crater, in the first week of June of 2005, and the creation of a new crater in July. In 2006 the most significant explosive activity took place during April, May and July, when the eruptive columns reached heights of more than 1500 meters above the crater, occasionally forming small pyroclastic flows. In May of 2007 morphological changes were observed in the summit. Among them a crater explosion on the East side, a new dome was formed on the West side, with 20 m in high and 50 m in diameter. The explosive events continue to date, but they have diminished in size and intensity. This activity was similar to the one observed in 1902-1903 and reported by Severo Diaz (1906), but without reaching the maximum levels of activity reported for 1903, where it had levels of three to five maximum explosive events per day. The photographs and the digital mapping have provided detailed information to quantify the dynamic evolution of the volcanic structures that developed on the summit of the volcano in the course of the last for years.

  6. Chemistry of surface water at a volcanic summit area, Norikura, central Japan: multivariate statistical approach.

    PubMed

    Anazaw, K; Ohmori, L H

    2001-11-01

    Many hydrochemical studies on chemical formation of shallow ground water have been reported as results of water-rock interaction, and contamination of paleo-brine or human activities, whereas the preliminary formation of precipitation source in the recharged region has not been established yet. The purpose of this research work is to clarify the geochemical process of water formation from a water source unpolluted by seawater or human activity. Norikura volcano, located in western part of central Japan provided a suitable source for this research purpose, and hence chemical compositions of water samples from the summit and the mountainside area of Norikura volcano were determined. Most samples in the summit area showed very low electrical conductivity, and lower than 12 microS/cm. On the basis of the chemical compositions, principal component analysis (PCA) and factor analysis (FA), such as kinds of multivariate statistical techniques were used to extract geochemical factors affecting hydrochemical process. As a result, three factors were extracted. The first factor showed high loading on K+, Ca2+, SO2 and SiO2, and this factor was interpreted due to influence of the chemical interaction between acidic precipitated water and rocks. The second factor showed high loading on Na+ and Cl-, and it was assumed to be an influence of seawater salt. The third factor showed loading on NO3-, and it was interpreted to be caused by biochemical effect of vegetation. The proportionate contributions of these factors to the evolution of water chemical composition were found to be 45%, 20%, and 10% for factors 1, 2 and 3, respectively. The same exploration at the mountainside of Norikura volcano revealed that the chemical variances of the non-geothermal water samples were highly influenced by water-rock interactions. The silicate dissolution showed 45% contribution for all chemical variances, while the adsorption of Ca2+ and Mg2+ by precipitation or ion exchange showed 20

    We report the first detailed study of diffuse emission of carbon dioxide (CO2), hydrogen sulfide (H2S), helium (He), and hydrogen (H2) from the summit crater of Pico do Fogo volcano, Cape Verde. Diffuse CO2, H2S, He, and H2 gas fluxes were measured at 57 sampling sites and ranged up to 12,800, 13, 1, and 6 g m-2 day-1, respectively. Soil temperature measurements at each sampling site were used to evaluate the heat flux. Most of the summit crater shows relatively high CO2 efflux, with highest values close to the fumarolic area, suggesting a structural control of the degassing process. In contrast, H2S effluxes were negligible or very low at the summit crater, except close to the fumarolic area where anomalously high CO2 efflux and soil temperatures were also measured. We estimate total CO2, H2S, He, and H2 diffuse gas fluxes of 219 t day-1, 25, 4, and 33 kg day-1, respectively. Based on a H2O/CO2 mass ratio of 1.52 measured at the fumaroles, we estimate a diffuse steam flux from the summit crater of approximately 330 t day-1. The enthalpy of this steam is equivalent to a heat flux of about 10.3 MW. The diffuse gas emission and thermal energy released from the summit crater of Pico do Fogo volcano are comparable to those observed at other volcanoes. Sustained surveillance of Pico do Fogo using these methods will be valuable for monitoring the activity of one of the most active volcanoes in the Atlantic Ocean.

    Characterizing climatic changes in the high-altitude mountain regions helps scientists and policy makers understand the effects of such changes on water resources, economic development, and the health of ecosystems. This paper proposes a change-point analysis to determine the time and magnitude of summer temperature changes in the summit areas of Romanian Carpathians between 1961 and 2007. Due to their altitude, massiveness, and position, Romanian Carpathians are an important barrier for different types of air masses between Western and Southeastern Europe. The results show that the change in summer temperatures occurred shortly after 1980. The average magnitude of this change is consistent with changes occurring in other parts of Southern Europe in the same time period although the magnitude of changes at individual weather stations may differ substantially. We aided our analysis by a statistical method based on regression models with serially correlated ARMA errors.

  9. Disturbance of the Boundary Layer at Summit Station, Greenland by an Atmospheric River

    Neff, William; Shupe, Mathew; Ralph, Marty

    2014-05-01

    On 11 July 2012, a rare melt episode occurred at Summit Station Greenland. As described by Neff et al. 2014 (Submitted JGR), a major factor in this melt event was an Atmospheric River (AR), a narrow corridor of high water-vapor content. This AR transited the western Atlantic and theen moved up the west coast of Greenland and thence over Greenland. Back trajectories also indicated significant warm air advection from mid-North America during a major heat wave. We present here the boundary layer changes during this event using sodar to distinguish well-mixed from stable periods and relate these to changes in synoptic forcing and resulting changes in radiative forcing by low-level, shallow, warm clouds. A second near-melt episode also occurred on 29 July which provides an opportunity to compare and contrast boundary layer responses in the two cases.

    The paper characterizes the mineralogy and spectral properties of three slightly palagonitized basaltic tephra samples collected near the summit of Mauna Kea in order to contribute to the basis for inferring mineralogy and processes for Martian surface materials. The mineralogy of size fractions of these samples is examined by diffuse reflectance and FIR spectroscopy, optical microscopy, X-ray diffraction, Moessbauer spectroscopy, magnetic analysis, EMPA, TEM, and SEM. For the 20-1000 micron size fraction, sample HWMK11 (red) is essentially completely oxidized and has a hematite (Ti-hematite) pigment dispersed throughout the silicate matrix. Sample HWMK12 (black) has the lowest proportion of ferric-bearing phases and is thus least weathered. For HWMK11, the amount of hematite is essentially constant, and mica is present only in the coarse clay-sized fraction; smectites are low in structural Fe.

    A fast-response chemiluminescence ozone analyzer was used to measure ozone as a function of both height and time in the near surface atmosphere at Summit Camp, Greenland during the summer 2009 season. The sampling line inlet for this ozone analyzer was mounted on a unique motorized moving platform which continuously sampled vertical ozone profiles between approximately 0.02 to 2 meters above the snowpack. Measurement periods lasted between one and 24 hours. Ozone concentrations showed significant temporal and vertical variability. Various meteorological data as well as turbulence parameters derived from measurements by three sonic anemometers located on a nearby 10-m flux tower are utilized to show the dependence of ozone behavior on atmospheric stability regimes and exchanges at the snowpack surface.

    The Western Area Power Administration (Western) needs to rebuild the existing Summit-Watertown 115-kV transmission line, located in northeastern South Dakota, and western Minnesota. Nearly 60 percent of the existing facility was replaced in 1965 after severe ice-loading broke structures and wires. Because of the extensive loss of the line, surplus poles had to be used to replace the damaged H-frame structures. These were of varying sizes, causing improper structure loading. Additionally, the conductors and overhead shield wires have been spliced in numerous places. This provides additional space on these wires for icing and wind resistance, which in turn create problems for reliability. Finally, a progressive fungal condition has weakened the poles and, along with the improper loading, has created an unsafe condition for maintenance personnel and the general public.

    The paper characterizes the mineralogy and spectral properties of three slightly palagonitized basaltic tephra samples collected near the summit of Mauna Kea in order to contribute to the basis for inferring mineralogy and processes for Martian surface materials. The mineralogy of size fractions of these samples is examined by diffuse reflectance and FIR spectroscopy, optical microscopy, X-ray diffraction, Moessbauer spectroscopy, magnetic analysis, EMPA, TEM, and SEM. For the 20-1000 micron size fraction, sample HWMK11 (red) is essentially completely oxidized and has a hematite (Ti-hematite) pigment dispersed throughout the silicate matrix. Sample HWMK12 (black) has the lowest proportion of ferric-bearing phases and is thus least weathered. For HWMK11, the amount of hematite is essentially constant, and mica is present only in the coarse clay-sized fraction; smectites are low in structural Fe.

    Pico do Fogo volcano is the youngest and most active volcano of the Cape Verde archipelago and rises over 2,800 m above sea level. It is located to the east of the Bordiera semicircular escarpment at Fogo Island and is capped by a 500-m-wide, 150-m-deep summit crater. Soil gas geochemical surveys in volcanic areas are useful tool to identify changes in volcanic activity related to magmatic processes. Among these studies, to monitor spatial and secular variations of soil CO2 and H2S effluxes pattern can provide important information about the state of activity of the volcanic system. CO2 has been one of the most studied gases in volcanic environments. Many studies have shown that significant amounts of CO2 are released to the atmosphere by quiescent volcanoes and geothermal systems through soil diffuse degassing. Since the emission rate of diffuse CO2 can increase dramatically prior to an eruption (e.g., Hernández et al. 2001a; Carapezza et al. 2004), efforts have to be made to obtain a CO2 flux baseline for a given volcanic system. However, and mainly due to analytical limitations, very few works on diffuse H2S emission have been carried out at volcanic-hydrothermal areas. With the aim of improving the geochemical surveillance program of Pico do Fogo, periodic soil degassing surveys have been performed at the summit crater of this volcano, focusing on the diffuse CO2 and H2S emissions. Temporal and spatial variations of CO2 and H2S efflux have been used to improve the knowledge about the degassing processed and their relationships with the volcanic activity. Each diffuse CO2 and H2S survey has been carried out following the accumulation chamber method at 40-65 sites homogeneously distributed at Pico do Fogo summit crater covering an area of about 0.142 km2. Soil CO2 and H2S efflux distribution maps were constructed following a Sequential Gaussian Simulation (sGs) in order to distinguish areas with anomalous CO2 and H2S emission rates and to compute the total gas

    The third annual ARPA-E Energy Innovation Summit was held in Washington D.C. in February, 2012. The event brought together key players from across the energy ecosystem - researchers, entrepreneurs, investors, corporate executives, and government officials - to share ideas for developing and deploying the next generation of energy technologies. Dr. Steven Chu, Energy Secretary, gave the first keynote presentation of the day. He discusses how President Obama's 'all-of-the-above' approach to energy will help the Unites States solve 21st century global energy challenges and maintain its leadership as an exporter of energy technology. Secretary of Energy Steven Chu highlighted our vulnerability to price fluctuations in the fuel markets, most recently to oil and gasoline, as well as our inability to drill our way out of the problem. Secretary Chu made the case for leveraging energy innovation in order to reduce our exposure to oil price fluctuations and improve the U.S.'s economic competitiveness.

    This report describes the SummitView 1.0 computer code developed at Sandia National Laboratories. SummitView is designed to generate a 3D solid model, amenable to visualization and meshing, that represents the end state of a microsystem fabrication process such as the SUMMiT (Sandia Ultra-Planar Multilevel MEMS Technology) V process. Functionally, SummitView performs essentially the same computational task as an earlier code called the 3D Geometry modeler [1]. However, because SummitView is based on 2D instead of 3D data structures and operations, it has significant speed and robustness advantages. As input it requires a definition of both the process itself and the collection of individual 2D masks created by the designer and associated with each of the process steps. The definition of the process is contained in a special process definition file [2] and the 2D masks are contained in MEM format files [3]. The code is written in C++ and consists of a set of classes and routines. The classes represent the geometric data and the SUMMiT V process steps. Classes are provided for the following process steps: Planar Deposition, Planar Etch, Conformal Deposition, Dry Etch, Wet Etch and Release Etch. SummitView is built upon the 2D Boolean library GBL-2D [4], and thus contains all of that library's functionality.

    A colleague walked by my office one time as I was conducting a meeting. There were about five or six members of my team present. The colleague, a man who had been with our institution (The Johns Hopkins Applied Physics Lab, a.k.a. APL) for many years, could not help eavesdropping. He said later it sounded like we we re having a raucous argument, and he wondered whether he should stand by the door in case things got out of hand and someone threw a punch. Our Advanced Composition Explorer (ACE) team was a hot group, to invoke the language that is fashionable today, although we never thought of ourselves in those terms. It was just our modus operandi. The tenor of the discussion got loud and volatile at times, but I prefer to think of it as animated, robust, or just plain collaborative. Mary Chiu and her "hot" team from the Johns Hopkins Applied Physics Laboratory built the Advanced Composition Explorer spacecraft for NASA. Instruments on the spacecraft continue to collect data that inform us about what's happening on our most important star, the Sun.

    Multi-instrument, ground-based measurements provide unique and comprehensive data sets of the atmosphere for a specific location over long periods of time and resulting data compliment past and existing global satellite observations. This paper explores the effect of ice hydrometeors on ground-based, high-frequency passive microwave measurements and attempts to isolate an ice signature for summer seasons at Summit, Greenland, from 2010 to 2013. Data from a combination of passive microwave, cloud radar, radiosonde, and ceilometer were examined to isolate the ice signature at microwave wavelengths. By limiting the study to a cloud liquid water path of 40 g m-2 or less, the cloud radar can identify cases where the precipitation was dominated by ice. These cases were examined using liquid water and gas microwave absorption models, and brightness temperatures were calculated for the high-frequency microwave channels: 90, 150, and 225 GHz. By comparing the measured brightness temperatures from the microwave radiometers and the calculated brightness temperature using only gas and liquid contributions, any residual brightness temperature difference is due to emission and scattering of microwave radiation from the ice hydrometeors in the column. The ice signature in the 90, 150, and 225 GHz channels for the Summit Station summer months was isolated. This measured ice signature was then compared to an equivalent brightness temperature difference calculated with a radiative transfer model including microwave single-scattering properties for several ice habits. Initial model results compare well against the 4 years of summer season isolated ice signature in the high-frequency microwave channels.

  2. The Thermal Circulation on Kilimanjaro, Tanzania and its Relevance to Summit Ice-Field Mass Balance.

    It is well known that mountains create their own climates. On Kilimanjaro, which is the tallest free standing mountain in Africa, the intense tropical sunlight generates a strong diurnal mountain circulation which transports moisture up the mountain during the day and back downslope at night. This process has strong consequences for development of cloud cover, precipitation, and hence ice-field mass balance on the summit crater. We compare surface climate (temperature, moisture and wind) measured at ten elevations on Kilimanjaro, with equivalent observations in the free atmosphere from NCEP/NCAR reanalysis data for September 2004 to July 2008. There are no simple temporal trends over this period in either surface of free- air data. Correlations between daily surface and free air temperatures are greatest below 2500 metres, meaning that synoptic (inter-diurnal) variability is the major control here. In contrast, temperatures and moisture on the higher slopes above treeline (about 3000 m) are strongly decoupled from the free atmosphere, showing intense heating/cooling by day/night (more than 5°C). The sparsely vegetated upper slopes are the focus for the most intense heating and upslope winds develop by mid-morning. The forest on the lower slopes acts as a moisture source, with large vapour pressure excesses reported (5 mb) which move upslope reaching the crater in the afternoon before subsiding downslope at night. The montane thermal circulation is more effective at upslope moisture transport during January as compared with July. Fluctuations in upper air flow strength and direction (at 500 mb) surprisingly have limited influence on the strength of surface heating and upslope moisture advection. This finding suggests that local changes in surface characteristics such as deforestation could have a strong influence on the mountain climate and the summit ice fields on Kilimanjaro, and make mass-balance somewhat divorced from larger-scale advective changes associated

    Multibeam (1 m resolution) and side scan data collected from an autonomous underwater vehicle, and lava samples, radiocarbon-dated sediment cores, and observations of flow contacts collected by remotely operated vehicle were combined to reconstruct the geologic history and flow emplacement processes on Axial Seamount's summit and upper rift zones. The maps show 52 post-410 CE lava flows and 20 precaldera lava flows as old as 31.2 kyr, the inferred age of the caldera. Clastic deposits 1–2 m thick accumulated on the rims postcaldera. Between 31 ka and 410 CE, there are no known lava flows near the summit. The oldest postcaldera lava (410 CE) is a pillow cone SE of the caldera. Two flows erupted on the W rim between ∼800 and 1000 CE. From 1220 to 1300 CE, generally small eruptions of plagioclase phyric, depleted, mafic lava occurred in the central caldera and on the east rim. Larger post-1400 CE eruptions produced inflated lobate flows of aphyric, less-depleted, and less mafic lava on the upper rift zones and in the N and S caldera. All caldera floor lava flows, and most uppermost rift zone flows, postdate 1220 CE. Activity shifted from the central caldera to the upper S rift outside the caldera, to the N rift and caldera floor, and then to the S caldera and uppermost S rift, where two historical eruptions occurred in 1998 and 2011. The average recurrence interval deduced from the flows erupted over the last 800 years is statistically identical to the 13 year interval between historical eruptions.

    Condensate samples were collected in 1992 from a high-temperature (300?? C) fumarole on the floor of the Halemaumau Pit Crater at Kilauea. The emergence about two years earlier of such a hot fumarole was unprecedented at such a central location at Kilauea. The condensates have hydrogen and oxygen isotopic compositions which indicate that the waters emitted by the fumarole are composed largely of meteoric water, that any magmatic water component must be minor, and that the precipitation that was the original source to the fumarole fell on a recharge area on the slopes of Mauna Loa Volcano to the west. However, the fumarole has no tritium, indicating that it taps a source of water that has been isolated from atmospheric water for at least 40 years. It is noteworthy, considering the unstable tectonic environment and abundant local rainfall of the Kilauea and Mauna Loa regions, that waters which are sources to the hot fumarole remain uncontaminated from atmospheric sources over such long times and long transport distances. As for the common, boiling point fumaroles of the Kilauea summit region, their 18O, D and tritium concentrations indicate that they are dominated by recycling of present day meteoric water. Though the waters of both hot and boiling point fumaroles have dominantly meteoric sources, they seem to be from separate hydrological regimes. Large concentrations of halogens and sulfur species in the condensates, together with the location at the center of the Kilauea summit region and the high temperature, initially suggested that much of the total mass of the emissions of the hot fumarole, including the H2O, might have come directly from a magma body. The results of the present study indicate that it is unreliable to infer a magmatic origin of volcanic waters based solely on halogen or sulfur contents, or other aspects of chemical composition of total condensates. ?? 1995 Springer-Verlag.

    Sun-lit snow is increasingly recognized as a chemical reactor that plays an active role in uptake, transformation, and release of atmospheric trace gases. Snow is known to influence boundary layer air on a local scale, and given the large global surface coverage of snow may also be significant on regional and global scales. We present a new detailed one-dimensional snow chemistry module that has been coupled to the 1-D atmospheric boundary layer model MISTRA. The new 1-D snow module, which is dynamically coupled to the overlaying atmospheric model, includes heat transport in the snowpack, molecular diffusion, and wind pumping of gases in the interstitial air. The model includes gas phase chemical reactions both in the interstitial air and the atmosphere. Heterogeneous and multiphase chemistry on atmospheric aerosol is considered explicitly. The chemical interaction of interstitial air with snow grains is simulated assuming chemistry in a liquid-like layer (LLL) on the grain surface. The coupled model, referred to as MISTRA-SNOW, was used to investigate snow as the source of nitrogen oxides (NOx) and gas phase reactive bromine in the atmospheric boundary layer in the remote snow covered Arctic (over the Greenland ice sheet) as well as to investigate the link between halogen cycling and ozone depletion that has been observed in interstitial air. The model is validated using data taken 10 June-13 June, 2008 as part of the Greenland Summit Halogen-HOx experiment (GSHOX). The model predicts that reactions involving bromide and nitrate impurities in the surface snow can sustain atmospheric NO and BrO mixing ratios measured at Summit, Greenland during this period.

    The Central European Watershed divides the Rhine-Main catchment and the Danube catchment. In the Early Medieval period, when ships were important means of transportation, Charlemagne decided to link both catchments by the construction of a canal connecting the Schwabian Rezat and the Altmühl rivers. The artificial waterway would provide a continuous inland navigation route from the North Sea to the Black Sea. The shortcut is known as Fossa Carolina and represents one of the most important Early Medieval engineering achievements in Europe. Despite the important geostrategic relevance of the construction it is not clarified whether the canal was actually used as a navigation waterway. We present new geophysical data and in situ findings from the trench fills that prove for the first time a total length of the constructed Carolingian canal of at least 2300 metres. We have evidence for a conceptual width of the artificial water course between 5 and 6 metres and a water depth of at least 60 to 80 cm. This allows a crossing way passage of Carolingian cargo scows with a payload of several tons. There is strong evidence for clayey to silty layers in the trench fills which reveal suspension load limited stillwater deposition and, therefore, the evidence of former Carolingian and post-Carolingian ponds. These findings are strongly supported by numerous sapropel layers within the trench fills. Our results presented in this study indicate an extraordinarily advanced construction level of the known course of the canal. Here, the excavated levels of Carolingian trench bottoms were generally sufficient for the efficient construction of stepped ponds and prove a final concept for a summit canal. We have evidence for the artificial Carolingian dislocation of the watershed and assume a sophisticated Early Medieval hydrological engineering concept for supplying the summit of the canal with adequate water.

  9. New field and laboratory evidence for the origin of hyaloclastite flows on seamount summits

    Smith, Terri L.; Batiza, Rodey

    1989-03-01

    New field observations with the submersible ALVIN and photographic evidence from a study of the summits of seamounts near the East Pacific Rise show that hyaloclastite deposits occur commonly. Hyaloclastite outcrops were found on six volcanoes at depths from 1240 to 2500 m. These new observations plus laboratory study of new hyaloclastite specimens extend the results of previous studies. Most of the hyaloclastite samples are of hydrovolcanic eruptive origin, but a few show evidence of a predominantly sedimentary origin. Primarily from morphology, we identify several vent areas from which hyaloclastite presumably erupted. The surface appearance of the hyaloclastite deposits varies with distance to these vents, leading us to propose a facies model for deep-sea hyaloclastites on seamount summits. Hyaloclastites of hydromagmatic origin exhibit weak normal grading and bedding-parallel alignment of platy shards. They consist of blocky, sliver and fluidal basalt glass shards and lithics in a matrix that contains pelagic sediment. The shards themselves are remarkably free of even the tiniest crystals and are usually chemically homogeneous. We propose that the shards form mainly by cooling-contraction granulation, but cannot rule out the possibility of limited steam explosivity. Hyaloclastites are closely associated with submarine pahoehoe and we propose that a very rapid eruption rate, promoting clastic-dominated versus flow-dominated eruptive behavior, is the dominant control on hyaloclastite formation. We propose that shard formation occurs during submarine lava fountaining. Gravitational instability of the resulting slurry of shards, sea water and possibly steam causes gravity flow that carries the shards outward from the vent. Further field and modelling studies are needed to test these ideas and more quantitatively constrain the ascent mechanism, eruption dynamics and deposition of deep-sea hyaloclastites.

    The Central European Watershed divides the Rhine-Main catchment and the Danube catchment. In the Early Medieval period, when ships were important means of transportation, Charlemagne decided to link both catchments by the construction of a canal connecting the Schwabian Rezat and the Altmühl rivers. The artificial waterway would provide a continuous inland navigation route from the North Sea to the Black Sea. The shortcut is known as Fossa Carolina and represents one of the most important Early Medieval engineering achievements in Europe. Despite the important geostrategic relevance of the construction it is not clarified whether the canal was actually used as a navigation waterway. We present new geophysical data and in situ findings from the trench fills that prove for the first time a total length of the constructed Carolingian canal of at least 2300 metres. We have evidence for a conceptual width of the artificial water course between 5 and 6 metres and a water depth of at least 60 to 80 cm. This allows a crossing way passage of Carolingian cargo scows with a payload of several tons. There is strong evidence for clayey to silty layers in the trench fills which reveal suspension load limited stillwater deposition and, therefore, the evidence of former Carolingian and post-Carolingian ponds. These findings are strongly supported by numerous sapropel layers within the trench fills. Our results presented in this study indicate an extraordinarily advanced construction level of the known course of the canal. Here, the excavated levels of Carolingian trench bottoms were generally sufficient for the efficient construction of stepped ponds and prove a final concept for a summit canal. We have evidence for the artificial Carolingian dislocation of the watershed and assume a sophisticated Early Medieval hydrological engineering concept for supplying the summit of the canal with adequate water.

    The differential availability of iron during hypoxia is presumed to affect the functioning of cardiac and skeletal myocytes. Rat H9C2 cardiomyocytes and L6G8C5 myocytes were cultured for 48 h in normoxic or hypoxic conditions at the optimal, reduced or increased iron concentration. The mRNA expression levels of markers of apoptosis [B‑cell lymphoma‑2 (Bcl2; inhibition) and Bcl‑2‑activated X protein (Bax; induction)], atrophy (Atrogin), glycolysis (pyruvate kinase 2; PKM2) and iron metabolism [transferrin receptor 1 (TfR1; iron importer), ferroportin 1 (FPN1; iron exporter), ferritin heavy chain (FTH; iron storage protein) and hepcidin (HAMP; iron regulator)] were determined using reverse transcription‑quantitative polymerase chain reaction, and cell viability was measured using an tetrazolium reduction assay. Cardiomyocytes and myocytes, when exposed to hypoxia, demonstrated an increased Bax/Bcl‑2 gene expression ratio (P<0.05). Additional deferoxamine (DFO) treatment resulted in further increases in Bax/Bcl‑2 in each cell type (P<0.001 each) and this was associated with the 15% loss in viability. The analogous alterations were observed in both cell types upon ammonium ferric citrate (AFC) treatment during hypoxia; however, the increased Bax/Bcl‑2 ratio and associated viability loss was lower compared with that in case of DFO treatment (P<0.05 each). Under hypoxic conditions, myocytes demonstrated an increased expression of PKM2 (P<0.01). Additional DFO treatment caused an increase in the mRNA expression levels of PKM2 and Atrogin‑1 (P<0.001 and P<0.05, respectively), whereas AFC treatment caused an increased mRNA expression of PKM2 (P<0.01) and accompanied decreased mRNA expression of Atrogin‑1 (P<0.05). The expression augmentation of PKM2 during hypoxia was greater upon low iron compared with that of ferric salt treatment (P<0.01). Both cell types upon DFO during hypoxia demonstrated the increased expression of TfR1

    BACKGROUND. In September 2008, under the French Presidency of the European Union and with the support of the Polish Minister of Health, a European Summit on Age-Related Disease was organised inWroclaw (Poland). At this meeting, European politicians, gerontologists and geriatricians gathered to discuss a common approach to future challenges related to age-related disease. Politicians and decision-makers from the European Union and Ministers of Health and their deputies from many European countries raised the problems and difficulties to be tackled in a growing population with a high burden of disease, and asked scientists to write a consensus document with recommendations for future actions and decisions. Scientists and clinicians worked in parallel in three different groups, on health promotion and preventive actions, basic research in age-related disease, and clinical aspects of disease in older people. Beforehand, the format of the paper with recommendations was discussed, and it was finally agreed that, for a better understanding by decision- makers, it would be divided in two different columns: one with facts that were considered settled and agreed by most experts (under the heading We know), and a second with recommendations related to each fact (We recommend). No limit on the number of topics to be discussed was settled. After careful and detailed discussion in each group, which in most cases included the exact wording of each statement, chairpersons presented the results in a plenary session, and new input from all participants was received, until each of the statements and recommendations were accepted by a large majority. Areas with no consensus were excluded from the document. Immediately after the Summit, the chairpersons sent the document both to the main authors and to a list of experts (see footnote) who had made presentations at the summit and agreed to review and critically comment on the final document, which is presented below.

    Colima Volcano, located in the West of the Volcanic Mexican Belt (19° 30.696 N, 103° 37.026 W), has shown a new cycle of explosive activity beginning May 30 1999, and reaching its maximum in March-April of 2005 and January 2013. In the 2005 the explosive activity increased gradually, having the largest event on May 23, when a new dome was created. Hours later this dome was destroyed by a strong explosion, forming an ash column 5.6 km high with subsequent pyroclastic flows that reached a distance of 4.2 km flowing along the ravines of the South sector. On May 30 the most intense explosion in 1999 occurred, when the plume reached heights in excess of 4.4 km above the crater, and pyroclastic flows were created. On the same year in July two explosive events occurred of characteristics similar to those in May. These constant explosions caused continuous morphological changes in the summit, the most significant being the collapse of the North and South walls of the crater, in the first week of June of 2005, and the creation of a new crater in July. In 2006 the most significant explosive activity took place during April, May and July, when the eruptive columns reached heights of more than 1500 meters above the crater, occasionally forming small pyroclastic flows. In May of 2007 morphological changes were observed in the summit. Among them a crater explosion on the East side, a dome was formed on the West side, with 20 m in high and 50 m in diameter. Since the end of 2008 to December of 2012 the volcano remained calm, with a dome diameter of 220 m and height of 60 m, in January 2013 three explosions occurred, destroying the dome and throwing a volume of 1.5 million cubic meters. The eruptive column reached a height of 3000 above the crater. It reported light ashfall to the NE to 100 km away from the volcano. The explosive events continue to date, but they have diminished in size and intensity. This activity was similar to the one observed in 1902-1903 and reported by

    The emission rate of carbon dioxide escaping from the summit of Kīlauea Volcano, Hawaiʻi, proved highly variable, averaging 4900 ± 2000 metric tons per day (t/d) in June–July 2003 during a period of summit inflation. These results were obtained by combining over 90 measurements of COSPEC-derived SO2emission rates with synchronous CO2/SO2 ratios of the volcanic gas plume along the summit COSPEC traverse. The results are lower than the CO2 emission rate of 8500 ± 300 t/d measured by the same method in 1995–1999 during a period of long-term summit deflation [Gerlach, T.M., McGee, K.A., Elias, T., Sutton, A.J. and Doukas, M.P., 2002. Carbon dioxide emission rate of Kīlauea Volcano: Implications for primary magma and the summit reservoir. Journal of Geophysical Research-Solid Earth, 107(B9): art. no.-2189.]. Analysis of the data indicates that the emission rates of the present study likely reflect changes in the magma supply rate and residence time in the summit reservoir. It is also likely that emission rates during the inflation period were heavily influenced by SO2 pulses emitted adjacent to the COSPEC traverse, which biased CO2/SO2 ratios towards low values that may be unrepresentative of the global summit gas plume. We conclude that the SO2 pulses are consequences of summit re-inflation under way since 2003 and that CO2 emission rates remain comparable to, but more variable than, those measured prior to re-inflation.

    It is proposed that many summit basins along the Aleutian Arc form from the clockwise rotation of blocks of the arc massic. Summit basins are arc-parallel grabens or half-grabens formed within the arc massif and are commonly located near or along the axis of late Cenozoic volcanism. Geomorphically, the Aleutian Arc appears to consist of contiguous rhombic blocks of varying size, 10's to 100's of km in length. Presents a model for block rotation that involves translation of blocks parallel to an arc. It is suggested that block rotation, which appears to have accelerated in late Cenozoic time, is linked to: 1) a shift in the Euler pole for the Pacific plate; 2) the consequential start-up of late Cenozoic volcanism; 3) improved interplate coupling instigated by sediment flooding of the Aleutian Trench; and 4) westward subduction of NE striking segments of the inactive Kula-Pacific Ridge.-from Authors

  5. Holocene collapse of a mountain summit in the Belledonne massif (France): evidence from geomorphological mapping

    Rock avalanching is a high magnitude / low frequency process in mountain environment. It is an extremely rapid flow of fragmenting rock particles, with a volume > 1 M m3, involving a large amount of energy and travelling farther than expected with a normal sliding friction law. Rock avalanches are not uncommon in the Alps, in particular because of debuttressing of rock slopes due to glacier retreat and downwasting since the last Glacial maximum. The upper Vorz catchment basin is one of the few still glaciarized basins in the Belledonne massif (French external crystalline massif, peaking at 2977 m a.s.l.). A deposit related to a rock avalanche lies at the Habert du Mousset (1680 m a.s.l.), covering an area of 95 000 m2, tens of meters-thick and with a volume exceeding 1 M of m3. A geomorphological study suggests that the deposit should result from the collapse of the palaeo-summit of Roche Rousse (2753 m a.s.l. at present). The main part of the collapsed volume fell on the east side of the mountain ridge, but a smaller part probably travelled along the west side to form the deposit of the Habert du Mousset. Vertical and horizontal travel distances would have been 1100 m and 2750 m, respectively. The apparent coefficient of friction (height-over-length H/L ratio) is 0.4, indicating a highly mobile rock avalanche (H/L ratio is 0.62 with a ‘normal' coefficient of friction). Two elements support the hypothesis of a Holocene collapse: (i) glacial striations, rat tails, chattermarks and grooves are present on roches moutonnées up to 20 m to the crest. Those inherited glacial forms required a glacier thick enough to erode the bedrock. Because the surface of the Last Glacial Maximum glacier was standing well below this site (> 1000 m), only a local glacier could have form, which would have been impossible with the present topography. Thus, the palaeo-summit of Roche Rousse collapsed not before the Lateglacial. As suggested by (ii) the very steep, sometimes overhanging

    In our study, two temperature values were extracted from model data fields for comparisons to NOAA's near-surface temperature data at the Greenland Summit. For each model, a 2-m temperature (interpolated between the surface and 1st model layer) and the modeled surface temperature were extracted. Five models were studied for the following dates, resolutions, grid sizes, and model elevations. The models investigated are: 1) NASA's Modern-Era Retrospective Analysis for Research and Applications (MERRA, 2008-2013, 1 hr, ½ deg. lat. by 2/3 deg. lon., 3184.94 m); 2) MERRA-Replay, (2008-2013, 3 hr, 1 degree, 3157.2 m); 3) the Ohio State University's Arctic System Reanalysis (ASR, 2008-2012, 3 hr, 30x30 km, 3121.75 m); 4) the NCEP Climate Forecast System Reanalysis (CFSR, 2008-2009, 6 hr, ~0.25 degree, 3167.99 m); and 5) the ECMWF-Interim Re-Analysis (ERAI, 2008-2014, 6 hr, ~1/2 degree, 3168.78 m). Temperature comparisons were done by aligning the closest 1-minute mean temperatures from the in situ sensor with the model temperatures (all times are UTC). Preliminary results were assessed primarily from scatter plots and detailed temperature comparisons during the unusual July 2012 melt event at Summit. Our results show considerable spread in the modeled temperatures across the annual temp range (±10K) relative to the NOAA data. Curiously, the 2-meter temperatures are typically at a different slope than surface temperatures (i.e. rotation of the point cloud). In general, MERRA surface temperatures are too cold whereas the 2-m temperatures are too cold at the upper end of the temperature range and too warm at the low end (point cloud rotation). ASR surface temps are too cold at the lower end and slightly too warm at the upper end and also have an imposed 273.15 K maximum temperature at this location. ASR 2-meter temperatures are very close to the NOAA values overall but have a curving structure to the point cloud across the temperature range. CFSR surface temperatures are

    The axial summit trough is a nearly continuous feature along the East Pacific Rise from 9-10 deg. N. The AST marks the central spreading axis of the ridge, is the site of the bulk of the volcanic eruptions, and hosts the majority of hydrothermal vent sites. In the past, the AST has been interpreted to be a purely tectonic or purely volcanic feature. Detailed analysis of sidescan imagery and high-resolution microbathymetry are used to identify the morphology and structural variability of the axial summit trough (AST) along the EPR crest in the study area. We use these data to address questions related to the causes for variability in width and character of the AST and how those parameters relate to the morphology and volcanic history of adjacent seafloor, relationships between lava flows and faults and fissures developed within ~4 km of the AST, and the frequency and size of volcanic eruptions. With constraints from microbathymetry data and knowledge of the detailed volcanic contacts along the EPR 9-10N AST derived from Alvin and towed camera data, we explore models of AST formation in an effort to better understand relationships between dike intrusion and how extensional strain is accommodated across the EPR axis. Assuming purely tectonic origins for the AST, 3D boundary element modeling suggests that dike widths and the levels to which dikes rise beneath the EPR axis are variable along-axis. For well-mapped portions of the AST we are able to infer the number of dikes needed to produce its current geometry, and as a result, the timescale of formation. Where the ridge is most volcanically active, we find that modeled dike widths and depths are unreasonable, and suggest that volcanic overprinting has modified the character of the AST. We conclude that both volcanic and tectonic processes are responsible for the formation of the AST and that the balance between these parameters controls the physical characteristics of the AST observed on the seafloor today.

  8. Evidence Acquisition and Evaluation for Evidence Summit on Enhancing Provision and Use of Maternal Health Services through Financial Incentives

    Recognizing the need for evidence to inform US Government and governments of the low- and middle-income countries on efficient, effective maternal health policies, strategies, and programmes, the US Government convened the Evidence Summit on Enhancing Provision and Use of Maternal Health Services through Financial Incentives in April 2012 in Washington, DC, USA. This paper summarizes the background and methods for the acquisition and evaluation of the evidence used for achieving the goals of the Summit. The goal of the Summit was to obtain multidisciplinary expert review of literature to inform both US Government and governments of the low- and middle-income countries on evidence-informed practice, policies, and strategies for financial incentives. Several steps were undertaken to define the tasks for the Summit and identify the appropriate evidence for review. The process began by identifying focal questions intended to inform governments of the low-and middle-income countries and the US Government about the efficacy of supply- and demand-side financial incentives for enhanced provision and use of quality maternal health services. Experts were selected representing the research and programme communities, academia, relevant non-governmental organizations, and government agencies and were assembled into Evidence Review Teams. This was followed by a systematic process to gather relevant peer-reviewed literature that would inform the focal questions. Members of the Evidence Review Teams were invited to add relevant papers not identified in the initial literature review to complete the bibliography. The Evidence Review Teams were asked to comply with a specific evaluation framework for recommendations on practice and policy based on both expert opinion and the quality of the data. Details of the search processes and methods used for screening and quality reviews are described.

    From 10 May through 17 June 2007 and 6 June through 9 July 2008 intensive sampling campaigns at Summit, Greenland confirmed that active bromine chemistry is occurring in and above the snow pack at the highest part of the Greenland ice sheet (72°36´ N, 38°25´ W and 3.2 km above sea level). Direct measurements found BrO and soluble gas phase Br- mixing ratios in the low pptv range on many days (maxima < 10 pptv). Conversion of up to 200 pg m-3 of gaseous elemental mercury (GEM) to reactive gaseous mercury (RGM) and enhanced OH relative to HO2 plus RO2 confirm that active bromine chemistry is impacting chemical cycles even at such low abundances of reactive bromine species. However, it does not appear that Bry chemistry can fully account for observed perturbations to HOx partitioning, suggesting unknown additional chemical processes may be important in this unique environment, or that our understanding of coupled NOx-HOx-Bry chemistry above sunlit polar snow is incomplete. Rapid transport from the north Atlantic marine boundary layer occasionally caused enhanced BrO at Summit (just two such events observed during the 12 weeks of sampling over the two seasons). In general observed reactive bromine was linked to activation of bromide (Br-) in, and release of reactive bromine from, the snowpack. A coupled snow-atmosphere model simulated observed NO and BrO at Summit during a three day interval when winds were weak. The source of Br- in surface and near surface snow at Summit is not entirely clear, but concentrations were observed to increase when stronger vertical mixing brought free tropospheric air to the surface. Reactive Bry mixing ratios above the snow often increased in the day or two following increases in snow concentration, but this response was not consistent. On seasonal time scales concentrations of Br- in snow and reactive bromine in the air were directly related.

    Samples from Summit County, Colo., were fractionated for analyses of organic content and uranium. The uranium is related to organic content but not to type of organic matter. In one area uranium values are around 100 ppm in bulk samples and as much as 200 ppm in certain separated fractions of the samples; this is much higher than the 1-10 ppm normal uranium values for peat.

    Eruptive activity has occurred in the summit region of Mount Erebus over the last 95 ky, and has included numerous lava flows and small explosive eruptions, at least one plinian eruption, and at least one and probably two caldera-forming events. Furnace and laser step-heating 40Ar/39Ar ages have been determined for 16 summit lava flows and three englacial tephra layers erupted from Mount Erebus. The summit region is composed of at least one or possibly two superimposed calderas that have been filled by post-caldera lava flows ranging in age from 17 ?? 8 to 1 ?? 5 ka. Dated pre-caldera summit flows display two age populations at 95 ?? 9 to 76 ?? 4 ka and 27 ?? 3 to 21 ??4 ka of samples with tephriphonolite and phonolite compositions, respectively. A caldera-collapse event occurred between 25 and 11 ka. An older caldera-collapse event is likely to have occurred between 80 and 24 ka. Two englacial tephra layers from the flanks of Mount Erebus have been dated at 71 ?? 5 and 15 ?? 4 ka. These layers stratigraphically bracket 14 undated tephra layers, and predate 19 undated tephra layers, indicating that small-scale explosive activity has occurred throughout the late Pleistocene and Holocene eruptive history of Mount Erebus. A distal, englacial plinian-fall tephra sample has an age of 39 ?? 6 ka and may have been associated with the older of the two caldera-collapse events. A shift in magma composition from tephriphonolite to phonolite occurred at around 36 ka. ?? Springer-Verlag 2004.

    The 1989 Loma Prieta, California, earthquake is characterized by the lack of major, throughgoing, coseismic, right-lateral faulting along strands of the San Andreas fault zone in the epicentral area. Instead, throughout the Summit Ridge area there are zones of tension cracks and left-lateral fracture zones oriented about N45 deg W, that is, roughly parallel to the San Andreas fault in this area. The left-lateral fractures zones are enigmatic because their left-lateral slip is opposite to the right-lateral sense of the relative motion between the Pacific and North American plates. We suggest that the enigmatic fractures can be understood if we assume that coesiesmic deformation was by right-lateral shear across a broad zone, about 0.5 km wide and 4 km long, beneath Summit Ridge. Contrary to most previous reports on the Loma Prieta earthquake, which assert that coseismic, right-lateral ground rupture was restricted to considerable (greater than 4 km) depths in the epicentral area, we find that nearly all the right-lateral offset is represented at the ground surface by the Summit Ridge shear zone.

    Abstract Despite growing social acceptance of lesbians, gay men, bisexuals, and transgender (LGBT) persons and the extension of marriage rights for same-sex couples, LGBT persons experience stigma and discrimination, including within the healthcare system. Each population within the LGBT umbrella term is likely at elevated risk for cancer due to prevalent, significant cancer risk factors, such as tobacco use and human immunodeficiency virus infection; however, cancer incidence and mortality data among LGBT persons are lacking. This absence of cancer incidence data impedes research and policy development, LGBT communities' awareness and activation, and interventions to address cancer disparities. In this context, in 2014, a 2-day National Summit on Cancer in the LGBT Communities was convened by a planning committee for the purpose of accelerating progress in identifying and addressing the LGBT communities' concerns and needs in the spheres of cancer research, clinical cancer care, healthcare policy, and advocacy for cancer survivorship and LGBT health equity. Summit participants were 56 invited persons from the United States, United Kingdom, and Canada, representatives of diverse identities, experiences, and knowledge about LGBT communities and cancer. Participants shared lessons learned and identified gaps and remedies regarding LGBT cancer concerns across the cancer care continuum from prevention to survivorship. This white paper presents background on each of the Summit themes and 16 recommendations covering the following: sexual orientation and gender identity data collection in national and state health surveys and research on LGBT communities and cancer, the clinical care of LGBT persons, and the education and training of healthcare providers.

    Recognizing the need for evidence to inform policies, strategies, and programs to care for vulnerable children, the U.S. Government convened an Evidence Summit on Protecting Children Outside of Family Care on December 12-13, 2011, in Washington, DC, USA. This paper summarizes the background and methods for the acquisition and evaluation of the evidence used to achieve the goals of the Summit. A multistep process was undertaken to identify the appropriate evidence for review. It began by identifying crucial focal questions intended to inform low and middle income governments and the U.S. Government about effective systems for protecting children outside family care. This was followed by a systematic attempt to gather relevant peer reviewed and gray literature that would inform these focal questions. The search processes, methods used for screening and quality reviews are described. In addition, members of the Evidence Review Teams were invited to add relevant papers not identified in the initial literature review to complete the bibliographies. These teams were asked to comply with a specific evaluation framework for recommendations on practice and policy based on both expert opinion and the quality of the data. This was the first U.S. Government Evidence Summit originating in the U.S. Agency for International Development Global Health Bureau and valuable lessons were learned on the identification and assessment of evidence informing complex development challenges.

    The expectations of attendees, the evaluations of themes, and the implications for continuing medical education (CME) identified by "Congress 2000: A Continuing Medical Education Summit on the Practices, Opportunities and Priorities for the New Millennium" are reviewed. A vision was identified with significant opportunities for CME to become a more valuable partner in and contributor to quality health care. The vision suggests that CME should be linked more closely to physician learning at the point of care and that technology might be used more successfully to address physician-learner needs by helping them to manage volumes of evidence for treating patients more effectively. At the same time, health care outcome data to analyze the need for and measure the effectiveness of educational interventions should become integrated into standards of practice for CME providers. Continuous improvement based on research about effective learning processes and outcomes should become an essential construct of the CME culture. Implications are summarized for the profession, organizational CME providers, individual CME professionals, and CME research from this new vision of CME crafted at Congress 2000.

    The 2002 United Nations World Summit On Sustainable Development (WSSD) at Johannesburg, South Africa wrought in significant turn-around on attitudes toward energy as the delegates came to recognize that energy is at the heart of sustainable development. As history demonstrates, developing countries will not suppress their need to convert environmental resources into energy to generate economic growth. Nations require the capability to generate local and regional incomes, not “transfer wealth” if they are to develop. And the WSSD also brought acknowledgement that developing countries cannot be expected to invest in expensive efforts to curb their production of greenhouse gasses. When the need for energy gained WSSD recognition, the European Union intensified their demand for renewable energy targets. Such targets quickly became a stumbling block for energy negotiations as the developed countries recognized that most of the challenge would fall upon them. The U.S. target, for instance, would require that 12% of all U.S. energy be generated by renewables by the year 2012.

    The SERI results for the Photovoltaic Solar Energy Project (PEP) 1987 summit round robin are presented and the proposed International Electrotechnical Commission (IEC) technical committee TC82 global calibration method is evaluated in this report. The global calibration method has a +-4% uncertainty in the short-circuit current (I/sub sc/) including random and nonrandom error sources. This uncertainty can be reduced +-3% if the global normal method is used and the direct component of the total irradiance is measured with a primary absolute cavity radiometer. Nearly half of the uncertainty for various primary and secondary PV calibration methods is nonrandom. If a +-4% uncertainty in I/sub sc/ under standard reporting conditions is acceptable, then the global calibration method with spectral corrections is suitable for cells or modules. If a primary reference device with an uncertainty less than +-3% is required, then the global method is unsuitable. The SERI primary direct normal calibration method has a +-1% uncertainty in I/sub sc/ as verified by comparison with primary AMO cells. If a +-1% primary reference cell is used for secondary calibrations, then a +-2% uncertainty could be achieved for reference cells or modules. 37 refs., 29 figs., 42 tabs.

    Understanding the state of the Greenland Ice Sheet (GIS) and how it is responding to climate change is critical to assessing the state of the cryosphere and the potential impacts of climate change on natural systems and society. This study assesses the state of the GIS in northern Greenland, using current and historical observations over a 1200 km transect from Thule to Summit. Historical observations made by Benson (1962) between 1952-1955 include snowpits and shallow cores that characterized the physical properties of (the preceding) one to two decades of accumulation, and allowed him to identify transitions between glacial facies. Our observations, collected in 2010 and 2011, include comparable measures as well as kinematic GPS, ground-penetrating radar, near infrared photography, and extensive chemistry. By linking physical measures with remotely sensed data, physical properties associated with snow accumulation and glacier facies can be examined over large distances. We highlight initial findings from the '2Barrels' field site located between Thule and Camp Century, spatially coincident with a NASA Operation IceBridge (OIB) flight line. Using physical observations and near infrared imagery, we evaluate ground-penetrating radar for characterizing snow and firn stratigraphy. We also present an initial comparison between our ground-based measurements and OIB airborne sensors.

    This study considers whether spurious peaks in nitrate ions in snow sampled at Summit, Greenland from August 2000 to August 2002 are related to solar proton events. After identifying tropospheric sources of nitrate on the basis of correlations with sulfate, ammonium, sodium, and calcium, we use the three-dimensional global Whole Atmosphere Community Climate Model (WACCM) to examine unaccounted for nitrate spikes. Model calculations confirm that solar proton events significantly impact HOx, NOx, and O3 levels in the mesosphere and stratosphere during the weeks and months following the major 9 November 2000 solar proton event. However, SPE-enhanced NOy calculated within the atmospheric column is too small to account for the observed nitrate ion peaks in surface snow. Instead, our WACCM results suggest that nitrate spikes not readily accounted for by measurement correlations are likely of anthropogenic origin. These results, consistent with other recent studies, imply that nitrate spikes in ice cores are not suitable proxies for individual SPEs and motivate the need to identify alternative proxies.

    Objective The objective of this project was to develop core competencies in pain assessment and management for prelicensure health professional education. Such core pain competencies common to all prelicensure health professionals have not been previously reported. Methods An interprofessional executive committee led a consensus-building process to develop the core competencies. An in-depth literature review was conducted followed by engagement of an interprofessional Competency Advisory Committee to critique competencies through an iterative process. A 2-day summit was held so that consensus could be reached. Results The consensus-derived competencies were categorized within four domains: multidimensional nature of pain, pain assessment and measurement, management of pain, and context of pain management. These domains address the fundamental concepts and complexity of pain; how pain is observed and assessed; collaborative approaches to treatment options; and application of competencies across the life span in the context of various settings, populations, and care team models. A set of values and guiding principles are embedded within each domain. Conclusions These competencies can serve as a foundation for developing, defining, and revising curricula and as a resource for the creation of learning activities across health professions designed to advance care that effectively responds to pain.

    The Chestnut Ridge anticline is the westernmost of the High Plateau folds in southwestern Pennsylvania and north-central West Virginia that are detached primarily in the Marcellus Shale, and the Martinsburg, Salina, and Rome Formations. The primary, basal detachment at the Summit field occurs in the Salina salt. Production from fracture porosity in the Devonian Oriskany Sandstone commenced in 1936. During the late 1980s and early 1990s, 14 wells were drilled preparatory to conversion of the reservoir to gas storage. Schlumberger`s Formation MicroScanner (FMS) logs were run in each of these wells to provide information on the structural configuration and fracture patterns of the reservoir. These data indicate that two inward-facing, tight folds at the Oriskany level form the upper flanks and core of the anticline at the northern end of the field, whereas the main part of the field to the south is a comparatively simple, broad closure at the Oriskany level. The structure is a broad, slightly asymmetric open fold in the Mississippian Greenbrier Formation at the surface. Fracture patterns mapped using FMS logs indicate a complex fracture system which varies slightly along the trend of the fold and among the units analyzed, including the Helderberg Formation, Huntersville Chert, Oriskany Sandstone, and Onondaga Formation. An orthogonal joint system strikes toward the northwest and northeast slightly askew to the trend of the fold`s crestal trace. A similar, but more complex fracture pattern is found in an oriented core of these units.

    Abstract The Third International Right Heart Summit was organized for the purpose of bringing an interdisciplinary group of expert physician-scientists together to promote dialogue involving emerging concepts in the unique pathophysiology, clinical manifestation, and therapies of pulmonary vascular disease (PVD) and right heart failure (RHF). This review summarizes key ideas addressed in the section of the seminar entitled “Transplantation in End-Stage Pulmonary Hypertension.” The first segment focused on paradigms of recovery for the failing right ventricle (RV) within the context of lung-alone versus dual-organ heart-lung transplantation. The subsequent 2-part section was devoted to emerging concepts in RV salvage therapy. A presentation of evolving cell-based therapy for the reparation of diseased tissue was followed by a contemporary perspective on the role of mechanical circulatory support in the setting of RV failure. The final talk highlighted cutting-edge research models utilizing stem cell biology to repair diseased tissue in end-stage lung disease—a conceptual framework within which new therapies for PVD have potential to evolve. Together, these provocative talks provided a novel outlook on how the treatment of PVD and RHF can be approached. PMID:25610607

    Measurements of ground-level visible sunlight (400-600 nm) from Summit, Greenland over the period August 2004 through October 2014 define the attenuation provided by cloudiness, including its dependence on solar elevation and season. The long-term mean cloud-attenuation increases with increasing solar zenith angle, consistent with radiative transfer calculations which treat a cloud as a plane parallel layer with a strong bias toward forward scattering and an albedo for diffuse radiation near 0.1. The ratio of measured irradiance to clear-sky irradiance for solar zenith angles greater than 66° has a small, but statistically significant, positive correlation with the previous day's magnetic activity as measured by the daily Ap index, but no clear relationship exists between the irradiance ratio and daily changes in the ground-level neutron flux measured at Thule over the time frame considered. A high value of Ap on one day tends to be followed by a day whose ground-level solar irradiance is slightly greater than would occur otherwise. In an average sense, the visible irradiance following a day with Ap>16 exceeds that following a day with Ap≤16 by 1.2-1.3% with a 95% confidence range of approximately ±1.0%. The results are broadly compatible with small changes in atmospheric scattering following magnetic disturbances.

    The 2007 Summit on “Environmental Challenges to Reproductive Health and Fertility” convened scientists, health care professionals, community groups, political representatives and the media to hear presentations on the impact of environmental contaminants on reproductive health and fertility and to discuss opportunities to improve health through research, education, communication and policy. Environmental reproductive health focuses on exposures to environmental contaminants, particularly during critical periods of development, and their potential effects on future reproductive health, including conception, fertility, pregnancy, adolescent development and adult health. Approximately 87,000 chemical substances are registered for use in commerce in the US, with ubiquitous human exposures to environmental contaminants in air, water, food and consumer products. Exposures during critical windows of susceptibility may result in adverse effects with lifelong and even intergenerational health impacts. Effects can include impaired development and function of the reproductive tract and permanently altered gene expression, leading to metabolic and hormonal disorders, reduced fertility and fecundity and illnesses such as testicular, prostate, uterine and cervical cancers later in life. This executive summary reviews effects of pre- and post-natal exposures on male and female reproductive health and provides a series of recommendations for advancing the field in the areas of research, policy, health care and community action.

    A study was made of possible hazardous working conditions at Consolidated Freightways, Pocono Summit, Pennsylvania. The request concerned potential exposure of dock workers to exhaust emissions from diesel-powered forklift trucks brought about by the health complaints of several of the workers there. Twenty-one workers were identified as symptomatic of exposure to diesel exhaust fumes. This included at least half of the midnight shift. Upper respiratory tract irritation was mentioned by all of these workers. Some reported eye irritation, cough productive of black-tinged sputum, and sore throat. These symptoms lessened during periods away from work. Airborne concentrations of all components measured at the site were well below the applicable exposure limits. A potential health hazard associated with exposure to diesel engine exhaust existed. The authors recommend that whenever a forklift truck is to be left unattended for more than the shortest of periods, the motor should be turned off. The newer forklifts should be used on a shift before the older, less emission controlled, lifts. Roof exhaust fans ordered are to be installed at the facility and their effectiveness evaluated.

    Non-methane hydrocarbons (NMHC) were measured in the ambient air and in the snowpack interstitial firn air at ˜1 m depth continuously for nearly two years at Summit, Greenland, from fall 2008 through summer 2010. Additionally, five firn air depth profiles were conducted to a depth of 3 m spanning winter, spring, and summer seasons. Here we report measurements of ethane, ethene, ethyne, propane, propene, i-butane, n-butane, i-pentane, n-pentane, and benzene and discuss the seasonal behavior of these species in the ambient and firn air. The alkanes, ethyne, and benzene in the firn air closely reflect the ambient air concentrations during all the seasons of the year. In spring and summer seasons, ethene and propene were enhanced in the near-surface firn over that in the ambient air, indicating a photochemical production mechanism for these species within the snowpack interstitial air. Evaluation of the NMHC ratios of i-butane/n-butane, i-pentane/n-pentane, and benzene/ethyne in both ambient and firn air does not provide evidence for chlorine or bromine radical chemistry significantly affecting these gases, except in a few summer samples, where individual data points may suggest bromine oxidation influence.

    The present study looks into aerosols collected by a land-based, seven-wavelength Aethalometer, from the lower-free troposphere close to the summit of the Pico mountain (top height: 2351 m; sampling height: 2225 m), in Pico island, Azores, Portugal. Following suitable handling and preparation procedures, all samples were put through instrumental neutron activation analysis (INAA; k{sub 0}-variant) for elemental assessment. Archival data have been used as an input to the HYSPLIT model (courtesy of NOAA ARL READY Website) for computing isentropic, backward trajectories of air masses reaching the Pico atmosphere. The results point to significant enrichments of molybdenum and uranium in high-altitude aerosols, especially in the summer samples. A local origin for either element is most unlikely though: Pico is a rural island, and there are no comparable records from low-altitude stations in the Azores at large. On the contrary, long-range transport from remote sources in continental areas--Europe and North-Central America--is rather compatible with the synoptic, elemental pathways converging over the Pico observatory for the period under study.

    The melt extent of the Greenland Ice Sheet (GIS) has been increasing in recent decades. According to a NASA press release, satellite observations show that the GIS melt extent was an anomalously high 97% in mid-July 2012, including rare melting at high altitude locations such as Summit, Greenland. This event was also captured by ground-based observations at Summit, collected by the ICECAPS (Integrated Characterization of Energy, Clouds, Atmospheric State, and Precipitation at Summit) project. The observational data also recorded increased variability in the atmospheric state for July 2012 compared to the July 2010 and 2011. One of the outliers on 11 July 2012 produced ice melt temperatures at Summit, Greenland for the first time since observational records began. The origin of the warm airmass that affected Summit on 11 July 2012 was traced to the central United States on 1 July 2012. Instead of flowing around the southern tip of Greenland, the airmass was forced over central Greenland and thus lifted to over 3200m by the thickness of the GIS. Temperature retrievals from a microwave radiometer (MWR) observed a warm front arriving on 10 July 2012, which included RH values close to saturation as recorded by a NOAA met tower. Elevated precipitable water vapor levels suggest ripe conditions for liquid water clouds. A low level liquid cloud was observed by a micropulse lidar (MPL) and a millimeter cloud radar (MMCR) from 10-11 July 2012 with elevated liquid water content retrieved from the MWRs. Observations from an infrared spectrometer (PAERI) instrument indicate increased downwelling longwave fluxes during this time. The liquid water cloud effectively traps the heat thus limiting the surface's ability to cool radiatively. Surface-based inversions are common during clear sky scenes but liquid bearing clouds often weaken these inversions. In combination with solar heating, this can create surface temperatures warmer than the air aloft. A conceptual surface energy

    Summit explosive activity and collapses that form pit craters and calderas represent major volcanic hazards on a dominantly effusive, frequently active volcano like Piton de la Fournaise. Only three summit collapse events (1986, 2002, 2007) have been recorded since the foundation of the Piton de la Fournaise volcano observatory (OVPF) in 1979, and two of them (1986 and 2007) were associated with weak phreatic activity. At Piton de la Fournaise, the normal explosive activity consists of short-lived and mild (< 20 m-high) lava fountains, which quickly evolve into strombolian activity during the eruptions. Based on comprehensive literature review and high-resolution image analysis of surface outcrops and summit caldera walls, we reconstructed the time distribution of recent explosive events (phreatomagmatic; phreatic) and their link with summit collapses and lateral (flank) effusive eruptions. In historical time (post-1640 CE), we recognise two main clusters of explosive events. Frequent and violent phreatomagmatic to phreatic explosions occurred during the oldest cluster (1708-1878) and alternated with long-lasting periods (years to decades) of summit effusive activity. In contrast, scarce, and on average, weak explosions occurred during the youngest cluster (1897-2012), when discrete and short-lived (< 6 months) effusive eruptions represent the main eruptive dynamics. Historical summit collapses (pit craters and caldera), all localised at the top of the summit cone, were related to voluminous lateral eruptions and were followed by a significant decrease in eruptive rate. However, magma draining during lateral eruptions was not systematically associated with summit collapses or explosions. The long-lasting occurrence of magma at very shallow depth below the volcano summit, followed by a rapid lateral drainage, apparently represents a critical condition favouring magma-groundwater interaction to produce explosive activity. The prehistoric growth of the Piton de la

    The 2706-2696 Ma Blake River megacaldera complex of the Archean Abitibi greenstone belt is composed of (1) the E-W, 40x80 km, ellipsoid, Misema caldera (MC) of predominantly tholeiitic basaltic composition, and (2) the NW-striking, 14x35 km, New Senator caldera (NSC) of both tholeiitic and calc-alkaline composition, and (3) the felsic, ENE-striking, 15x20k km, Noranda caldera (NC). The subaqueous Misema caldera, the size of Toba, hosts the two nested graben calderas NSC and NC. This megacaldera complex represents a world class gold-massive sulfide mining camp with abundant rock-Archean seawater interaction, km-scale hydrothermal alteration, and a recently discovered site of inferred early life in basalts. Between the inner and outer ring faults of the MC are circular to ellipsoid 2-12 km-scale gabbro to quartz diorite ring dyke complexes that represent the roots of summit calderas. The studied mafic summit calderas, comparable to the present day Axial Seamount, are centres of extensive subaqueous pyroclastic deposits and their reworked counterparts. The Montsabrais and Reneault volcanic centres (RVC) have 200-1000 m-thick volcaniclastic units in the core of the ring dyke complexes, and extensive km-long outflow facies. The 80-100 m-thick Jevis South Tuff and the Kino North Tuff are related to the RVC. The pyroclastic density current deposits are traceable on outcrop 500 metres along strike. Pyroclastic deposits are interstratified with pillowed mafic flows and black shale suggesting a calm, deep-water, subaqueous environment. Individual flow units are 5-50 m-thick and display fining-upward. Internal deposit geometry shows 3 main divisions: A) massive, matrix or clast supported, lapilli tuff breccia (2 - 25 m-thick); B) lapilli tuff with normal or inverse grading (1 - 10 m-thick); C-1) coarse- to fine-grained tuff with parallel to wavy stratification and low-angle crossbeds with erosive bases (0.5 - 15 m-thick), or C-2) beds of fine- to very fine-grained tuff with

    Flexible metabolic phenotypes allow animals to adjust physiology to better fit ecological or environmental demands, thereby influencing fitness. Summit metabolic rate (Msum = maximal thermogenic capacity) is one such flexible trait. Skeletal muscle and heart masses and myocyte metabolic intensity are potential drivers of Msum flexibility in birds. We examined correlations of skeletal muscle and heart masses and pectoralis muscle citrate synthase (CS) activity (an indicator of cellular metabolic intensity) with Msum in house sparrows (Passer domesticus) and dark-eyed juncos (Junco hyemalis) to determine whether these traits are associated with Msum variation. Pectoralis mass was positively correlated with Msum for both species, but no significant correlation remained for either species after accounting for body mass (Mb) variation. Combined flight and leg muscle masses were also not significantly correlated with Msum for either species. In contrast, heart mass was significantly positively correlated with Msum for juncos and nearly so (P = 0.054) for sparrows. Mass-specific and total pectoralis CS activities were significantly positively correlated with Msum for sparrows, but not for juncos. Thus, myocyte metabolic intensity influences Msum variation in house sparrows, although the stronger correlation of total (r = 0.495) than mass-specific (r = 0.378) CS activity with Msum suggests that both pectoralis mass and metabolic intensity impact Msum. In contrast, neither skeletal muscle masses nor pectoralis metabolic intensity varied with Msum in juncos. However, heart mass was associated with Msum variation in both species. These data suggest that drivers of metabolic flexibility are not uniform among bird species. PMID:24992186

  17. Thermal structure and heat loss at the summit crater of an active lava dome

    Forward-Looking Infrared (FLIR) nighttime thermal images were used to extract the thermal and morphological properties for the surface of a blocky-to-rubbley lava mass active within the summit crater of the Caliente vent at Santiaguito lava dome (Guatemala). Thermally the crater was characterized by three concentric regions: a hot outer annulus of loose fine material at 150-400°C, an inner cold annulus of blocky lava at 40-80°C, and a warm central core at 100-200°C comprising younger, hotter lava. Intermittent explosions resulted in thermal renewal of some surfaces, mostly across the outer annulus where loose, fine, fill material was ejected to expose hotter, underlying, material. Surface heat flux densities (radiative + free convection) were dominated by losses from the outer annulus (0.3-1.5 × 104 s-1m-2), followed by the hot central core (0.1-0.4 × 104 J s-1m-2) and cold annulus (0.04-0.1 × 104 J s-1m-2). Overall surface power output was also dominated by the outer annulus region (31-176 MJ s-1), but the cold annulus contributed equal power (2.41-7.07 MJ s-1) as the hot central core (2.68-6.92 MJ s-1) due to its greater area. Cooled surfaces (i.e. the upper thermal boundary layer separating surface temperatures from underlying material at magmatic temperatures) across the central core and cold annulus had estimated thicknesses, based on simple conductive model, of 0.3-2.2 and 1.5-4.3 m. The stability of the thermal structure through time and between explosions indicates that it is linked to a deeper structural control likely comprising a central massive plug, feeding lava flow from the SW rim of the crater, surrounded by an arcuate, marginal fracture zone through which heat and mass can preferentially flow.

  18. Basalt of Summit Creek: Eocene Magmatism Associated with Farallon Slab Break Off

    In the Pacific Northwest the Early-Middle Eocene was a time of widespread magmatism and tectonic reorganization that included accretion of the Siletzia terrane, Challis volcanism, and establishment of the modern Cascade arc. Although individual events are well documented our knowledge of the underlying tectonic framework is incomplete. To better understand the tectonic changes that occurred during this interval we studied the ~48 Ma Basalt of Summit Creek (BSC), a 1500m section of lavas located south of Mt. Rainier that erupted during the critical time period between the docking of Siletzia and the initiation of the modern Cascade arc. The BSC consists mainly of tholeiitic basalts (wt. % SiO2 = 45.54-63.45, Mg# = 0.68-0.30) with EMORB traits (La/YbN = 1.2-5.9; 206Pb/204Pb = 19.005-19.102; 207Pb/204Pb = 15.538-15.593; 208Pb/204Pb = 38.560-38.714). These lavas lack arc signatures (e.g., HFSE depletions) but overlap in elemental and isotopic composition with oceanic basalts of the Crescent Formation (part of Siletzia) located ~100 km to the west. We suggest that emplacement of lavas that lack arc traits in what was the forearc was a response to break off of the Farallon slab, which occurred as a result of the accretion of Siletzia at ~49 Ma (Wells et al., 2014). Break off opened a gap in the subducted slab, allowing upwelling and subsequent decompression melting. BSC lavas are consistent in age, location and composition with this model. After break off subduction resumed outboard of Siletzia, initiating the Cascade arc. Thus, BSC provides evidence of Farallon slab break off and furthers our understanding of the tectonic transition from widespread magmatism of the Early-Middle Eocene to the Cascade arc.

  19. Revised Record of Decision for the Electrical Interconnection of the Summit/Westward Project

    2004-10-21

    The Bonneville Power Administration (BPA) has decided to amend its July 25, 2003, Record of Decision (ROD) regarding the proposed Summit/Westward Project (Project) to offer contract terms for an optional interconnection of this Project into the Federal Columbia River Transmission System (FCRTS). Under this optional interconnection plan, BPA would integrate electric power from the Project into the FCRTS at a point adjacent to Clatskanie People's Utility District (CPUD) existing Wauna Substation. In order to deliver power to this location, CPUD would develop a new substation (Bradbury Substation) at a site near the Project and a new 230-kV transmission line from there to CPUD's Wauna Substation, which is already connected to the FCRTS. As part of this revised decision, BPA will facilitate CPUD development of the Bradbury-Wauna transmission line by allowing joint use of BPA right-of-way. This will involve reconstructing a section of BPA's 115-kV Allston-Astoria No. 1 transmission line from single-circuit H-frame wood-pole design to double-circuit single metal pole design. Terms of BPA participation in CPUD's development of the Bradbury-Wauna transmission line will be documented in a Construction Agreement. This optional interconnection plan is in addition to BPA's previous offer for interconnection of the Project at BPA's Allston Substation, as documented in the July 25, 2003, ROD. As with the initial interconnection plan, the decision to offer terms to interconnect the Project through the optional interconnection plan is consistent with BPA's Business Plan Final Environmental Impact Statement (BP EIS) (DOE/EIS-0183, June 1995), and the Business Plan Record of Decision (BP ROD, August 1995). This decision thus is similarly tiered to the Business Plan ROD.

    With more than 30 therapeutic monoclonal antibodies (mAbs) approved and annual global sales of the products at ~$50 billion in 2010, these products have proven to be successful in many ways. Nevertheless, there is room for improvement in performance, and substantial unmet medical needs remain. As a consequence, numerous organizations are devoting resources to engineering novel mAbs such as bispecific antibodies that have increased functionality compared with unmodified IgG molecules. The World Bispecific Antibody Summit, organized by Hanson Wade, drew over 100 participants to Boston to discuss engineering novel bispecific antibodies, generating lead candidates and clinical study and commercialization of the molecules. Approaches such as the trifunctional antibody (TRION), dual variable domain-Ig (Abbott), two-in-one (Genentech), dual affinity retargeting (MacroGenics), kappa-lambda body (NovImmune), bispecific T-cell engager (Micromet) and chemical generation (CovX/Pfizer) were discussed in detail. In addition, posters describing bispecific Affibody® molecules for targeting of EGFR and HER2 (Affibody), T-cell receptor based bi-specifics that target HLA-peptides (Immunocore), a novel mAb-Fv bispecific antibody format utilizing Fc region (Xencore), generation of a tetravalent bispecific antibody against IL4 and IL13 for the treatment of idiopathic pulmonary fibrosis (Sanofi), Combining Affibody® molecules and the Albumod™ technology to create long acting multispecific protein therapeutics (Royal Institute of Technology, Affibody) and COVA301 as a highly potent bispecific inhibitor of IL-17A and TNF-α (Covagen) were presented.

    Bulk deposition samples were collected at three elevated summits in different parts of the Alps from 2005 to 2010. Deposition samples were analyzed for a wide range of organochlorine pesticides (OCPs). HCHs, DDT, DDD, DDE, chlordanes, cis-heptachlor, HCB, dieldrin and endrin were found in all samples, only aldrin was found less frequently. Differences in the mean deposition rates between the three sites reflect the different amounts of precipitation at these sites. At the northern edge of the Alps with the highest annual total precipitations, mean annual deposition rates were at least twice those at the Swiss site for most of the investigated OCP. Average annual deposition of α-HCH amounted to 602, 461 and 216 ng m-2 year-1, the sum of DDT, DDD and DDE to 579, 210 and 144 ng m-2 year-1 and the sum of trans- and cis-chlordane to 35, 47, 16 ng m-2 year-1 at Zugspitze, Sonnblick, and Weissfluhjoch, respectively. A quite distinct seasonal pattern of OPC deposition was observed at all three locations. For most of the HCH isomers, higher deposition rates were observed in summer than in winter at all three sites, which may be caused by enhanced re-volatilization due to higher summer temperatures and the ongoing application of HCH-containing products in some regions as well. For the other investigated OCPs, higher summer deposition rates were found only at Weissfluhjoch. This site is more often affected by air masses crossing the river Po basin than the other two sites, an area exhibiting higher summer temperatures compared to other regions adjacent to the Alps.

    The NSF-sponsored Summit on the Future of Undergraduate Geoscience Education made major progress toward developing a collective community vision for the geosciences. A broad spectrum of the geoscience education community, ~200 educators from research universities/four and two year colleges, focused on preparation of undergraduates for graduate school and future geoscience careers, pedagogy, use of technology, broadening participation/retention of underrepresented groups, and preparation of K-12 science teachers. Participants agreed that key concepts, competencies and skills learned throughout the curriculum were more important than specific courses. Concepts included understanding Earth as complex, dynamic system, deep time, evolution of life, natural resources, energy, hazards, hydrogeology, surface processes, Earth materials and structure, and climate change. Skills/competencies included ability to think spatially and temporally, reason inductively and deductively, make and use indirect observations, engage in complex open, coupled systems thinking, and work with uncertainty, non-uniqueness, and incompleteness, as well as critical thinking, problem solving, communication, and ability to think like a scientist and continue to learn. Successful ways of developing these include collaborative, integrative projects involving teams, interdisciplinary projects, fieldwork and research experiences, as well as flipped classrooms and integration and interactive use of technology, including visualization, simulation, modeling and analysis of real data. Wider adoption of proven, effective best practices is our communities' main pedagogical challenge, and we focused on identifying implementation barriers. Preparation of future teachers in introductory and general geoscience courses by incorporating Next Generation Science Standards and using other sciences/math to solve real world geoscience problems should help increase diversity and number of future geoscientists and

    Dust originating from the Sahara desert can be uplifted during storms, transported across the Mediterranean towards the Alpine region and deposited during snowfalls. The microbes associated with dust particles can be involved in establishing microbiota in icy environments as well as affect ecosystem and human health. Our objective was to use a culture-free DNA-based approach to assess bacterial content and diversity and furthermore, to identify ‘icy' microbes which could be brought on the Mont Blanc (MtBl) summit with Saharan dust and became living in the snow. Saharan dust fallout on MtBl summit from one event (MB5, event June 2006) vs. control libraries and that from another event (May 2008) were collected in Grenoble (SD, 200 m a.s.l.) and at Col du Dome (MB-SD, 4250 m a.s.l.). Soil from Ksar Ghilane (SS, Saharan desert, Tunisia, March 2008) was taken for overall comparison as a possible source population. Fresh snow falling in Grenoble (85) was collected as example of diversity in this area. To assess the microbial diversity 16S rRNA gene libraries (v3-v5 region) were constructed for corresponding dust-snow samples (MB5, SS, SD, 85 and MB-SD) along with clear snow samples and several controls. For both MB5 and MB-SD samples full-gene technique was evoked in attempt to differentiate reproduced bacteria from damaged DNA. Before sequencing the clones were rybotyped. All clone libraries were distinct in community composition except for some single phylotypes (or closely related groups) overlap. Thus, clone libraries from two different events that were collected at Col du Dome area within 2 year interval (MB5 and MB-SD) were different in community composition except one of the abundant phylotype from MB-SD library (Geodermatophilus sp.) which was shared (98% sequence similarity) with single representative from MB-5 library. These bacteria are pigmented and radiation-resistant, so it could be an indicator of desert origin for our sequences. For MB5 library two

  14. A Comparison of Process-Scale Modeling and Measurements of Atmosphere-Snowpack Exchange of Nitrogen Oxides at Summit, Greenland

    Snowpack over glacial ice is a reservoir for reactive nitrogen gases. Previous studies indicate nitrogen oxides (NOx) are generated in snowpack interstitial air through photolysis of nitrate (NO3-). Gradients in NOx mixing ratios between snowpack interstitial air and the overlying atmosphere regulate NOx surface exchange, which affects the Arctic ozone budget and climate. To better understand the dynamics of cryosphere-atmosphere exchange of NOx in the Arctic, we use a 1-D process-scale model to evaluate measurements of NOxin and above the snowpack during March-May 2009 at Summit, Greenland. The model is based upon the processes previously presented in the snowpack chemistry and physics model, MISTRA-SNOW, which represents snow grains as spheres with surfaces uniformly coated by an aqueous phase. Modeled profiles of NO, NO2, and O3 up to ~ 2 meters deep into the snowpack for March-May 2009 have been compared to measured profiles and will be presented. During the March-May time period at Summit, low irradiances are observed during March, diurnal irradiance profiles are observed during April, and the sun never sets in May. The model results suggest a key chemical pathway for the formation of NO2 during "nighttime" that was previously unexplained. In addition, modeled 24-hour NOx fluxes are compared to measured NOx fluxes from a MET tower at Summit. Modeled fluxes of NOx in April 2009 are the same order of magnitude as the measurements; however, modeled fluxes of NOx deviate up to one order of magnitude from measurements in May 2009. A detailed analysis of the modeled/measured flux comparison will be presented.

  15. Digital Elevation Model Creation Using SfM on High-Altitude Snow-Covered Surfaces at Summit, Greenland

    NASA Astrophysics Data System (ADS)

    Millstein, J. D.; Hawley, R. L.

    2015-12-01

    Structure from Motion (SfM) provides a means through which a digital elevation model (DEM) can be constructed with data acquired at a relatively low cost when compared to other current alternatives. Using an Unmanned Aerial Vehicle (UAV), a large area can be efficiently covered at high spatial resolution to quantify regional topography. Structure from Motion applied to photogrammetric techniques from a UAV has proven to be a successful tool, but challenges to UAV-based SfM include high-altitude locations with few distinctive surface features and minor textural differences. In June 2015, we piloted a small UAV (Quest) in order to conduct a topographical survey of Summit Camp, Greenland using SfM. Summit Camp sits at a surface elevation of 3200 meters above sea level, and occupies a snow-covered surface. The flat, very uniform terrain proved to be a challenge when flying the UAV and processing imagery using SfM techniques. In this presentation we discuss the issues both with operating a UAV instrument platform at high-altitude in the polar regions and interpreting the resulting DEM from a snow-covered region. The final DEM of Summit Camp covers a large portion of the surface area directly impacted by camp activities. In particular, volume calculations of drifting snow gauge an estimate of the equipment hours that will be required to clear and unearth structures. Investigation of surface roughness at multiple length scales can similarly provide insight on the accuracy of the DEM when observing texturally uniform surfaces.

    Through a NOAA Environmental Literacy grant, ANDRILL (ANtarctic geological DRILLing) created a unique opportunity for both formal and informal educators to engage their classrooms/audiences in understanding the complexities of climate change. The program, entitled C2S2: Climate Change Student Summits, included excellent geographical coverage through an exceptional two-workshop professional development series for teachers in each of nine different regions representing the U.S. National Climate Assessment regions defined by the U.S. Global Change Research Program. The program also included a creative, investigative science research and presentation experience for teams of students in each region, culminating in the Climate Change Student Summit, an on-site capstone event including a videoconference connecting all sites. The success of this program is based on combining multiple aspects, such as providing professional development for educators and encouraging the active involvement of research scientists, both in the professional development workshops and in the Student Summit. Another key factor is the close working relationships between informal and formal education entities, including the involvement of informal science learning facilities and informal science education leaders. The program includes the creation and use of cutting-edge curriculum materials available in the ELF, (Environmental Literacy Framework with a focus on climate change) and hands-on resources for teachers and students that provide an earth systems approach to climate change education, which have been successfully used in grades 5-12 as well as at numerous science museums. The C2S2 project has completed four years of activities with demonstrated positive impacts on both students and teachers. This presentation will share the lessons learned about implementing this climate change science education program and suggest that it is a successful model that can be used to scale up this project from

    Analysis of microgravity and surface displacement data collected at the summit of Kīlauea Volcano, Hawaii (USA), between December 2009 and November 2012 suggests a net mass accumulation at ~1.5 km depth beneath the northeast margin of Halema‘uma‘u Crater, within Kīlauea Caldera. Although residual gravity increases and decreases are accompanied by periods of uplift and subsidence of the surface, respectively, the volume change inferred from the modeling of interferometric synthetic aperture radar deformation data can account for only a small portion (as low as 8%) of the mass addition responsible for the gravity increase. We propose that since the opening of a new eruptive vent at the summit of Kīlauea in 2008, magma rising to the surface of the lava lake outgasses, becomes denser, and sinks to deeper levels, replacing less dense gas-rich magma stored in the Halema‘uma‘u magma reservoir. In fact, a relatively small density increase (<200 kg m−3) of a portion of the reservoir can produce the positive residual gravity change measured during the period with the largest mass increase, between March 2011 and November 2012. Other mechanisms may also play a role in the gravity increase without producing significant uplift of the surface, including compressibility of magma, formation of olivine cumulates, and filling of void space by magma. The rate of gravity increase, higher than during previous decades, varies through time and seems to be directly correlated with the volcanic activity occurring at both the summit and the east rift zone of the volcano.

    From 10 May through 17 June, 2007 and 6 June through 9 July, 2008 intensive sampling campaigns at Summit, Greenland confirmed that active bromine chemistry is occurring in and above the snow pack at the highest part of the Greenland ice sheet (72°36' N, 38° 25' W and 3.2 km a.s.l.). Direct measurements found BrO and soluble gas phase Br- mixing ratios in the low pptv range on many days (maxima <10 pptv). Conversion of up to 200 pg m-3 of gaseous elemental mercury (GEM) to reactive gaseous mercury (RGM) and enhanced OH relative to HO2 plus RO2 confirm that active bromine chemistry is impacting chemical cycles even at such low abundances of reactive bromine species. However, it does not appear that Bry chemistry can fully account for observed perturbations to HOx partitioning, suggesting unknown additional chemical processes may be important in this unique environment, or that our understanding of coupled NOx-HOx-Bry chemistry above sunlit polar snow is incomplete. Rapid transport from the North Atlantic marine boundary layer occasionally caused enhanced BrO at Summit (just two such events observed during the 12 weeks of sampling over the two seasons). In general observed reactive bromine was linked to activation of bromide (Br-) in, and release of reactive bromine from, the snowpack. A coupled snow-atmosphere one-dimensional model that assumed snow photochemistry as the only source successfully simulated observed NO and BrO at Summit during a three day interval when winds were weak (transport not a factor). The source of Br- in surface and near surface snow at Summit is not entirely clear, but concentrations were observed to increase when stronger vertical mixing brought free tropospheric air to the surface. Reactive Bry mixing ratios above the snow often increased in the day or two following increases in snow concentration, but this response was not consistent. On seasonal time scales concentrations of Br- in snow and reactive bromine in the air were directly

    Nitrogen and oxygen isotopes of nitrate (NO3-) can be used to examine changes in nitrogen sources over time, as NO3- is the primary sink of nitrogen oxides (NOx) emissions from the atmosphere. This study presents a high-resolution, seasonal analysis of δ15N and δ18O of NO3- from an ice core collected at Summit, Greenland in 2010. The relationship between the δ15N record and major sources of NOx (fossil fuel combustion, biomass burning, and soil emission) was investigated using emissions data as well as isotopic, elemental, and molecular tracers, including tracers for oil and coal combustion (lead, sulfur, thallium, and cadmium) and biomass burning (black carbon and ammonium). The results show a marked negative trend in δ15N-NO3-, dropping 10‰ (vs. air N2) since pre-Industrial times from an average of 12.9‰ (1760-1810) to 2.9‰ (1952-2002), with the most rapid change occurring between 1960 and 1980. This overall trend can be attributed to significant changes in NOx sources since the Industrial Revolution. The relationships between the δ15N-NO3- signal and the tracers suggest that fossil fuel and soil NOx emissions have negative δ15N signatures, while biomass burning has a positive δ15N signature. The δ18O of NO3-, on the other hand, is not representative of source signals, but of the oxidation pathways in the atmosphere. The δ18O-NO3- ice core record displayed little change between pre- and post-Industrial eras, with only a slight increase of 2.6‰ from a pre-Industrial average of 73.2‰ (vs. VSMOW) to a post-Industrial average of 75.8‰. Importantly, the seasonality of the δ18O-NO3- signal, with higher values found in wintertime snow and lower values in summer, did not change throughout the record. The lack of any trend in the δ18O-NO3- signal is expected because seasonal photochemistry, the driving force of the seasonal δ18O signal, has not changed markedly during the past 250 years. In summary, the data from this study show that investigation

    During the summer 2005 and 2006 field seasons at Summit (3270 m) Greenland we collected snow core samples for comprehensive geochemical characterization. This sampling effort was one facet of our larger program with the overall objective of improving our understanding of the sourcing and post depositional diagenesis of organic carbon depositing on the Greenland ice sheet. From snow pits of 3-meter depth, representing ~4 years of recent accumulation, detailed profiles of a suite of chemical variables were obtained, including: total and water soluble organic carbon, particulate organic and elemental carbon, inorganic ions, and comprehensive elemental and isotopic analysis. The elemental characterization supports our source reconciliation efforts in providing sub-seasonal data on aerosol particulate matter chemistry from which sourcing vectors can be inferred. Elemental and isotopic analyses on the melted snow cores were carried-out using high-resolution (sector-field) ICP-MS (Finnegan Element 2). A large suite of elements were quantified, including: the major/crustal elements (Al, Ca, K, Fe. Na, Mg, Si), minor crustal elements (Ba, Cs, Li, Rb, Sc, Sr, Ti) light transition metals (Co, Cr, Cu, Mn, Ni, Zn), heavy transition metals (Ag, Cd, Hg, Pb, Tl, W), oxyanion metals (As, Mo, U, V), platinum group metals (Rh, Pd, Pt), rare earths (Ce, Er, Eu, La, Nd, Sm, Y, Yb), as well as, Be, Sb, Sn, sulfur and phosphorus. Very large (>30x) temporal variation in snow core concentrations were measured for Al, Ba, Cr, Cu, Fe, Mg, P, Rb, Sr, Ti, U, Zn and all the rare earths, while low variation (~5x) is observed for the elements As, Cd, Hg, Mo, S and Sn. The later group is representative of the more mobile, anthropogenically dominated/sourced trace metals. Principal crustal elements (Al, Ca, Fe, K, Mg, Na) and sulfate (S) present similar profiles, with significant burial peaks in spring. Major burial peaks are relatively uniformly spaced (~70 cm apart), indicating some consistency

  3. Downwelling longwave flux over Summit, Greenland, 2010-2012: Analysis of surface-based observations and evaluation of ERA-Interim using wavelets

    This study analyzes the downwelling longwave radiation (DLW) over the Greenland Ice Sheet (GrIS) using surface-based observations from Summit Station (72°N, 38°W; 3210 m) and the European Centre for Medium-Range Weather Forecasts Interim Reanalysis (ERA-Interim) DLW fields. Since surface-based observations are sparse in the Arctic, the accuracy of including reanalyses for spatial context is assessed. First, the DLW at Summit is reported, including the significant time scales of variability using time-frequency decomposition (wavelet analysis). A new method for evaluating reanalyses is then introduced that also uses wavelet analysis. ERA-Interim DLW performs reasonably well at Summit, but because it includes too many thin clouds and too few thick clouds, it is biased low overall. The correlation between the observations and ERA-Interim drops from r2 > 0.8 to near 0 for time series reconstructed from time scales less than ~4 days. These low correlations and additional analyses suggest that the spatial resolution of the data sets is a factor in representing variability on short time scales. The bias is low across all time scales and is thus likely tied to cloud generation processes in the model rather than the spatial representation of the atmosphere across the GrIS. The exception is autumn, when ERA-Interim overestimates the influence of clouds at time scales of 1 and 4 weeks. The spatial distribution of cloud influence on the DLW across the GrIS indicates that Summit is located in a transition zone with respect to cloud properties. The gradient across this transition zone is steepest near Summit in autumn, so the spatial characteristics of the atmosphere near Summit may contribute to the ERA-Interim bias during this time.

    2014-05-01

    Clouds and the atmospheric state play fundamental roles in the cryospheric mass budget of the Greenland Ice Sheet both as a source, via precipitation, and a potential sink, via modulation of the surface energy budget. In this study we use regional climate model simulations to identify the differing impact of local and remote moisture sources on cloud formation and the surface energy budget at Summit, Greenland. A focus of these studies is to investigate air mass sources that cause both mid-tropospheric ice clouds and mixed-phase stratocumulus to form and the interaction between these different cloud types. For example, how the modification of air masses aloft may prevent stratocumulus from forming by producing ice clouds through homogeneous freezing that precipitate ice into the boundary layer. Sensitivity studies will be presented and discussed that explore how perturbations to local and remote moisture sources, due to changes in sea surface temperatures and sea ice extent, impact cloud formation and the surface energy budget at Summit.

    Canada has one of the highest rates of inflammatory bowel disease (IBD) and the disease represents a significant health, social, and economic burden. There is currently no cure for IBD, although earlier diagnosis and new therapies have improved the overall health outcomes and quality of life for patients. Crohn's and Colitis Canada is Canada's only national, volunteer-based charity dedicated to finding cures for IBD and improving the lives of those affected, through research, education, patient programs, advocacy, and increased awareness. On April 30, 2015, Crohn's and Colitis Canada hosted the "Patient and Healthcare Professional Summit on the Burden of Disease in IBD" to obtain a deeper understanding of the unmet needs of IBD patients and their caregivers. Through personal vignettes, patients articulated a pressing need to increase understanding of the challenges faced by people suffering from IBD among both health care professionals and the general public, develop best practices for navigating life transitions and addressing the unique challenges faced by children with IBD, and provide equitable access to appropriate, effective, and affordable treatments. The recommendations that emerged from the summit will inform about efforts to increase public awareness, inform about advocacy strategies, and contribute to the development of research priorities.

  10. Brief report: pressure support ventilation during an ascent and on the summit of Mt. Everest? A theoretical approach.

    2002-01-01

    At extreme altitude, air has an almost identical composition compared to air at sea level, while its pressure is altitude-dependently lower. When supplementary oxygen is used to achieve an acceptable inspiratory pressure of oxygen (PI(O2)) during climbing, the barometric pressure difference to lower altitudes is not compensated for. In this report, we tried theoretically to apply pressure support ventilation (PSV) to partially compensate for low barometric pressures. PSV is widely used for respiratory home care and is applicable via a nasal mask. Since there are light-weight units with long battery lives on the market, we speculated that these units may to some extent replace bottled oxygen. PSV was in theory applied at barometric pressures of 400 torr (Everest Base Camp), 284 torr (South Col), and 253 torr (summit of Mt. Everest). We found that during PSV at a mean airway pressure of 16.5 torr on the summit of Mt. Everest, a fraction of inspired oxygen (FI(O2)) of 0.34 sufficed to achieve an alveolar partial pressure (PA(O2)) of 67 torr. PSV increases PI(O2) by 3.5 torr, which in theory elevates the maximum oxygen consumption (V(O2max)) by 218 mL.min(-1) in an acclimatized climber in this setting. An additional benefit of PSV at extreme altitude may come from the unloading of the respiratory muscles.

    A conference specific to the education and training of clinical neuropsychology was held in 1997, which led to a report published in the Archives of Clinical Neuropsychology (Hannay, J., Bieliauskas, L., Crosson, B., Hammeke, T., Hamsher, K., & Koffler, S. (1998). Proceedings of the Houston Conference on Specialty Education and Training in Clinical Neuropsychology. Archives of Clinical Neuropsychology, 13, 157-250.). The guidelines produced by this conference have been referred to as the Houston Conference (HC) guidelines. Since that time, there has been considerable discussion, and some disagreement, about whether the HC guidelines produced a positive outcome in the training of neuropsychologists. To explore this question and determine how widely the HC guidelines were implemented, a meeting was held in 2006. Present and past leaders of the American Psychological Association Division 40 (Clinical Neuropsychology), the National Academy of Neuropsychology, and the Association of Postdoctoral Programs in Clinical Neuropsychology met to discuss the possible need for an Inter-Organizational Summit on Education and Training (ISET). A decision was reached to have the ISET Steering Committee conduct a survey of clinical neuropsychologists that could address the extent to which HC guidelines were present in the specialty and whether the influence of the HC guidelines was positive. An online survey was constructed, with data gathered in 2010. The current paper presents and discusses the ISET survey results. Specific findings need to be viewed cautiously due to the relatively low response rate. However, with some direct parallels to a larger recent survey of clinical neuropsychologists, the following general conclusions appear well founded: (a) the demographics of respondents in the ISET survey are comparable with a recent larger professional practice survey and thus may reasonably represent the specialty; (b) the HC guidelines appear to have been widely adopted by training

    Phylogenetic analysis of three genes of Penguinpox virus, a novel Avipoxvirus isolated from African penguins, reveals its relationship to other poxviruses. The genes corresponding to Vaccinia virus G8R (VLTF-1), A3L (P4b) and H3L were sequenced and phylogenetic trees (Neighbour-Joining and UPGMA) constructed from MUSCLE nucleotide and amino acid alignments of the equivalent sequences from several different poxviruses. Based on this analysis, PEPV was confirmed to belong to the genus Avipoxvirus, specifically, clade A, subclade A2 and to be most closely related to Turkeypox virus (TKPV), Ostrichpox virus (OSPV)and Pigeonpox virus (PGPV).

    Increasing residential and commercial development is placing increased demands on the ground- and surface-water resources of Snyderville Basin, Park City, and adjacent areas in the southwestern corner of Summit County, Utah. Data collected during 1993-95 were used to assess the quantity and quality of the water resources in the study area. Ground water within the study area is present in consolidated rocks and unconsolidated valley fill. The complex geology makes it difficult to determine the degree of hydraulic connection between different blocks of consolidated rocks. Increased ground-water withdrawal during 1983- 95 generally has not affected ground-water levels. Ground-water withdrawal in some areas, however, caused seasonal fluctuations and a decline in ground-water levels from 1994 to 1995, despite greater-than-normal recharge in the spring of 1995. Ground water generally has a dissolved-solids concentration that ranges from 200 to 600 mg/L. Higher sulfate concentrations in water from wells and springs near Park City and in McLeod Creek and East Canyon Creek than in other parts of the study area are the result of mixing with water that discharges from the Spiro Tunnel. The presence of chloride in water from wells and springs near Park City and in streams and wells near Interstate Highway 80 is probably caused by the dissolution of applied road salt. Chlorofluorocarbon analyses indicate that even though water levels rise within a few weeks of snowmelt, the water took 15 to 40 years to move from areas of recharge to areas of discharge. Water budgets for the entire study area and for six subbasins were developed to better understand the hydrologic system. Ground-water recharge from precipitation made up about 80 percent of the ground-water recharge in the study area. Ground-water discharge to streams made up about 40 percent of the surface water in the study area and ground-water discharge to springs and mine tunnels made up about 25 percent. Increasing use of

    During the summer 2005 and 2006 field seasons at Summit (3270 m) Greenland we collected snow core samples for comprehensive geochemical characterization. From snow pits of 3-meter depth, dug in the clean-air sector, representing ~4 years of recent accumulation, detailed profiles (10 cm intervals) of: total and water soluble organic carbon, particulate organic and elemental carbon, inorganic ions, organic acids (LMWA), and comprehensive elemental and isotopic species were obtained. The elemental characterization supports our source reconciliation efforts in providing sub-seasonal data on aerosol particulate matter chemistry from which sourcing vectors can be inferred. Elemental analysis on the snow core sections was carried-out using magnetic-sector ICP-MS. A large suite of elements was quantified, including: the major/crustal elements (Al, Ca, K, Fe, Na, Mg, Si); minor crustal elements (Ba, Be, Cs, Li, Rb, Sc, Sr, Ti); light transition metals (Co, Cr, Cu, Mn, Ni, Zn); heavy transition metals (Ag, Cd, Hg, Pb, Tl, W); oxyanion metals (As, Mo, U, V); platinum group metals (Rh, Pd, Pt); rare earths (Ce, Er, Eu, La, Nd, Sm, Y, Yb); as well as semi- and non-metals Sb, Sn, S, and P. Signal-noise was adequate to quantify all but 4 of the 52 elements studied. Chemical profiles from separate cores collected in 2005 and 2006 exhibited excellent coherence (when offset by the 45 cm of annual snow deposition) between years, indicating that the deposition archive is relatively uniform and that the sampling and analytical methods applied were robust. Clearly resolved intra- and inter-annual burial patterns were apparent for most elements, with strong covariance between many; indicating that relatively few deposition modalities are represented. Large (>30x) temporal variation in snow core concentrations were measured for Al, Ba, Cr, Cu, Fe, Mg, P, Rb, Sr, Ti, U, Zn and all the rare earths, while low variation (~5x) was observed for the elements As, Cd, Hg, Mo, Pt, S and Sn.
