    Electrochemical cells and systems play a key role in a wide range of industry sectors. These devices are critical enabling technologies for renewable energy; energy management, conservation and storage; pollution control / monitoring; and greenhouse gas reduction. A large number of electrochemical energy technologies have been developed in the past. These systems continue to be optimized in terms of cost, life time and performance, leading to their continued expansion into existing and emerging market sectors. The more established technologies such as deep-cycle batteries and sensors are being joined by emerging technologies such as fuel cells, large format lithium-ion batteries, electrochemical reactors; ion transport membranes and supercapacitors. This growing demand (multi billion dollars) for electrochemical energy systems along with the increasing maturity of a number of technologies is having a significant effect on the global research and development effort which is increasing in both in size and depth. A number of new technologies, which will have substantial impact on the environment and the way we produce and utilize energy, are under development. This paper presents an overview of several emerging electrochemical energy technologies along with a discussion some of the key technical challenges.

    2012-07-30

    In the US and abroad, major research and development initiatives toward establishing a hydrogen-based transportation infrastructure have been undertaken, encompassing key technological challenges in hydrogen production and delivery, fuel cells, and hydrogen storage. However, the principal obstacle to the implementation of a safe, low-pressure hydrogen fueling system for fuel-cell powered vehicles remains storage under conditions of near-ambient temperature and moderate pressure. The choices for viable hydrogen storage systems at the present time are limited to compressed gas storage tanks, cryogenic liquid hydrogen storage tanks, chemical hydrogen storage, and hydrogen absorbed or adsorbed in a solid-state material (a.k.a. solid-state storage). Solid-state hydrogen storage may offer overriding benefits in terms of storage capacity, kinetics and, most importantly, safety.The fervor among the research community to develop novel storage materials had, in many instances, the unfortunate consequence of making erroneous, if not wild, claims on the reported storage capacities achievable in such materials, to the extent that the potential viability of emerging materials was difficult to assess. This problem led to a widespread need to establish a capability to accurately and independently assess the storage behavior of a wide array of different classes of solid-state storage materials, employing qualified methods, thus allowing development efforts to focus on those materials that showed the most promise. However, standard guidelines, dedicated facilities, or certification programs specifically aimed at testing and assessing the performance, safety, and life cycle of these emergent materials had not been established. To address the stated need, the Testing Laboratory for Solid-State Hydrogen Storage Technologies was commissioned as a national-level focal point for evaluating new materials emerging from the designated Materials Centers of Excellence (MCoE) according to

    Cold cesium or rubidium atomic samples have a good potential both for generation and storage of nonclassical states of light. Generation of nonclassical states of light is possible through the high non-linearity of cold atomic samples excited close to a resonance line. Quadrature squeezing......, polarization squeezing and entanglement have been demonstrated. Quantum state storage is made possible by the presence of long-lived angular momentum in the ground state. Cold atoms are thus a promising resource in quantum information....

    1991-09-01

    This document presents some basic ideas about developing plans for dealing with energy shortages and contains a range of topics and considerations that state government officials and planners may wish to review in formulating an energy emergency plan. Those states in advanced stages of plan development might wish to use this document as a means of reviewing their plans or for possible revisions or refinements. This document introduces a number of key factors and options from which states may choose when finalizing their energy emergency plans. The report is intended to serve as a vehicle for improving planning efforts and does not seek to provide criteria by which to judge or compare different states' plans. There are six basic steps to the planning format presented in this report. The remainder of this document builds upon the outline, providing additional detail on such topics as preliminary planning,legal issues, organizational structures, selection of mitigation measures, and historical reviews. Appendix A lists information sources, and Appendix B contains responses to the State Emergency Plan Survey, updated in October 1990.

    Bulk energy storage is generally considered an important contributor for the transition toward a more flexible and sustainable electricity system. Although economically valuable, storage is not fundamentally a "green" technology, leading to reductions in emissions. We model the economic and emissions effects of bulk energy storage providing an energy arbitrage service. We calculate the profits under two scenarios (perfect and imperfect information about future electricity prices), and estimate the effect of bulk storage on net emissions of CO2, SO2, and NOx for 20 eGRID subregions in the United States. We find that net system CO2 emissions resulting from storage operation are nontrivial when compared to the emissions from electricity generation, ranging from 104 to 407 kg/MWh of delivered energy depending on location, storage operation mode, and assumptions regarding carbon intensity. Net NOx emissions range from -0.16 (i.e., producing net savings) to 0.49 kg/MWh, and are generally small when compared to average generation-related emissions. Net SO2 emissions from storage operation range from -0.01 to 1.7 kg/MWh, depending on location and storage operation mode.

  19. State of emergency medicine in Colombia.

    2015-01-01

    Colombia is an upper-middle-income country with a population of 45 million people and one of the best national healthcare and medical education systems in South America. However, its widely diverse and difficult terrains hinder healthcare delivery to rural areas, creating disparities in healthcare access and outcomes between the urban and rural settings. Currently, emergency medical care is overwhelmingly provided by general practitioners without residency training, who obtain specialty consultations based on the medical/surgical condition identified. A few emergency medicine (EM) residency programs have sprouted over the last two decades in renowned academic institutions in the largest cities, producing high-quality EM specialists. With the establishment of EM as a specialty in 2005 and increasing recognition of the specialty, there has been an increasing demand for EM specialists in cities, which is only slowly being met by the current residencies. The critical challenges for EM in Colombia are both, establishing itself as a well-recognized specialty - by increasing academic production and reaching a critical mass of and unity among EM specialists - and providing the highest quality and safest emergency care to the people of Colombia - by improving capacity both in emergency departments and in the regional and national emergency response systems. Historically, the establishment of EM as a strongly organized specialty in other countries has spanned decades (e.g., the United States), and Colombia has been making significant progress in a similar trajectory.

    IEEE SSSWG was chartered in May 1990 to abstract the hardware and software components of existing and emerging storage systems and to define the software interfaces between these components. The immediate goal is the decomposition of a storage system into interoperable functional modules which vendors can offer as separate commercial products. The ultimate goal is to develop interoperable standards which define the software interfaces, and in the distributed case, the associated protocols to each of the architectural modules in the model. The topics are presented in viewgraph form and include the following: IEEE SSSWG organization; IEEE SSSWG subcommittees & chairs; IEEE standards activity board; layered view of the reference model; layered access to storage services; IEEE SSSWG emphasis; and features for MSSRM version 5.

    Full Text Available Seed emergence under field conditions decisively and directly determines the number of plants per hectare, which is one of three basic components of yield in the plant world. Influence of chemical treatment on field emergence of three commercial sunflower hybrids stored in different conditions was tested in 2007 and 2008 on experimental field of Institute of Field and Vegetable Crops in Novi Sad. On average, hybrid H1 had the highest value of field emergence (88.79% and for chemical treatment fl udioxonil + metalaxyl + imidacloprid (87.71%. Seed kept in common storage had the highest emergence value in fi eld (87.92%. Seed treated with fl udioxonil + metalaxyl + imidacloprid and stored for one year in common storage had the highest field emergence (90.18%. Considering interaction between storage conditions and genotype, hybrid H1 seed sown after chemical treatment had the highest field emergence (91.82% and seed kept in common storage (90.48%. Hybrid H1 seed compared with other two had the highest field emergence treated with fludioxonil + metalaxyl + imidacloprid (91.84%.

    The purpose of this report is to provide a summary of the emergency response laws and regulations in place in the various states within the southern region for use by legislators, emergency response planners, the general public and all persons concerned about the existing legal framework for emergency response. SSEB expects to periodically update the report as necessary. Radiation protection regulations without emergency response provisions are not included in the summary. The radiological emergency response laws and regulations of the Southern States Energy Compact member states are in some cases disparate. Several states have very specific laws on radiological emergency response while in others, the statutory law mentions only emergency response to ``natural disasters.`` Some states have adopted extensive regulations on the topic, others have none. For this reason, any general overview must necessarily discuss laws and regulations in general terms. State-by-state breakdowns are given for specific states.

    New Zealand (NZ), is a country subject to a wide range of natural disasters, some of which (e.g., floods and storms) may increase in frequency and severity with the effects of climate change. To improve disaster preparations, we aimed to use scenario development and linear programming to identify the lowest-cost foods for emergency storage. We used NZ food price data (e.g., from the Food Price Index) and nutritional data from a NZ food composition database. Different scenarios were modelled in Excel and R along with uncertainty analysis. A collection of low-cost emergency storage foods that meet daily energy requirements for men were identified e.g., at a median purchase cost of NZ$2.21 per day (equivalent to US$1.45) (95% simulation interval = NZ$2.04 to 2.38). In comparison, the cost of such a collection of foods which did not require cooking, was NZ$3.67 per day. While meeting all nutritional recommendations (and not just energy) is far from essential in a disaster setting, if such nutritionally optimised foods are purchased for storage, then the cost would be higher (NZ$7.10 per day). Where a zero level of food spoilage was assumed (e.g., storage by a government agency), the cost of purchasing food for storage was as low as NZ$1.93 per day. It appears to cost very little to purchase basic emergency foods for storage in the current New Zealand setting. The lists of the foods identified could be considered by organisations who participate in disaster relief (civil defence) but also by citizens.

  7. Creation, Storage, and On-Demand Release of Optical Quantum States with a Negative Wigner Function

    Directory of Open Access Journals (Sweden)

    Jun-ichi Yoshikawa

    2013-12-01

    Full Text Available Highly nonclassical quantum states of light, characterized by Wigner functions with negative values, have been all-optically created so far only in a heralded fashion. In this case, the desired output emerges rarely and randomly from a quantum-state generator. An important example is the heralded production of high-purity single-photon states, typically based on some nonlinear optical interaction. In contrast, on-demand single-photon sources are also reported, exploiting the quantized level structure of matter systems. These sources, however, lead to highly impure output states, composed mostly of vacuum. While such impure states may still exhibit certain single-photon-like features such as antibunching, they are not nonclassical enough for advanced quantum-information processing. On the other hand, the intrinsic randomness of pure, heralded states can be circumvented by first storing and then releasing them on demand. Here, we propose such a controlled release, and we experimentally demonstrate it for heralded single photons. We employ two optical cavities, where the photons are both created and stored inside one cavity and finally released through a dynamical tuning of the other cavity. We demonstrate storage times of up to 300 ns while keeping the single-photon purity around 50% after storage. Our experiment is the first demonstration of a negative Wigner function at the output of an on-demand photon source or a quantum memory. In principle, our storage system is compatible with all kinds of nonclassical states, including those known to be essential for many advanced quantum-information protocols.

    Hydrazine bisborane N2H4(BH3)2 (HBB; 16.8 wt %) recently re-emerged as a potential hydrogen storage material. However, such potential is controversial: HBB was seen as a hazardous compound up to 2010, but now it would be suitable for hydrogen storage. In this context, we focused on fundamentals of HBB because they are missing in the literature and should help to shed light on its effective potential while taking into consideration any risk. Experimental/computational methods were used to get a complete characterization data sheet, including, e.g., XRD, NMR, FTIR, Raman, TGA, and DSC. From the reported results and discussion, it is concluded that HBB has potential in the field of chemical hydrogen storage given that both thermolytic and hydrolytic dehydrogenations were analyzed. In solid-state chemical hydrogen storage, it cannot be used in the pristine state (risk of explosion during dehydrogenation) but can be used for the synthesis of derivatives with improved dehydrogenation properties. In liquid-state chemical hydrogen storage, it can be studied for room-temperature dehydrogenation, but this requires the development of an active and selective metal-based catalyst. HBB is a thus a candidate for chemical hydrogen storage.

    Full Text Available This study examines the Alabama Department of Corrections August 2009 Monthly Statistical Report and Fiscal Year 2008 Annual Report, recent articles to explain the serious public safety issue of prison overcrowding within the state of Alabama, lack of funding and correctional staff, and increasing violence among inmates. It is imperative that the stakeholders take a restorative justice approach to offenders who commit nonviolent crimes or otherwise be prepared to release substantial numbers of violent inmates due to federal court intervention, expanding parole, and other types of early release programs. Violent offenders will pose a greater threat to the community. Correctional workers continue to be exposed daily to the risk of injury or death caused by severe prison overcrowding. The state could experience additional financial hardship to rebuild a destroyed correctional facility in an event of a riot. The excessive use of incarceration for nonviolent offenders is one of the most important issues facing the state of Alabama this decade.

  14. Physical principles and current status of emerging non-volatile solid state memories

    Science.gov (United States)

    Wang, L.; Yang, C.-H.; Wen, J.

    2015-07-01

    Today the influence of non-volatile solid-state memories on persons' lives has become more prominent because of their non-volatility, low data latency, and high robustness. As a pioneering technology that is representative of non-volatile solidstate memories, flash memory has recently seen widespread application in many areas ranging from electronic appliances, such as cell phones and digital cameras, to external storage devices such as universal serial bus (USB) memory. Moreover, owing to its large storage capacity, it is expected that in the near future, flash memory will replace hard-disk drives as a dominant technology in the mass storage market, especially because of recently emerging solid-state drives. However, the rapid growth of the global digital data has led to the need for flash memories to have larger storage capacity, thus requiring a further downscaling of the cell size. Such a miniaturization is expected to be extremely difficult because of the well-known scaling limit of flash memories. It is therefore necessary to either explore innovative technologies that can extend the areal density of flash memories beyond the scaling limits, or to vigorously develop alternative non-volatile solid-state memories including ferroelectric random-access memory, magnetoresistive random-access memory, phase-change random-access memory, and resistive random-access memory. In this paper, we review the physical principles of flash memories and their technical challenges that affect our ability to enhance the storage capacity. We then present a detailed discussion of novel technologies that can extend the storage density of flash memories beyond the commonly accepted limits. In each case, we subsequently discuss the physical principles of these new types of non-volatile solid-state memories as well as their respective merits and weakness when utilized for data storage applications. Finally, we predict the future prospects for the aforementioned solid-state memories for

  16. The state of energy storage in electric utility systems and its effect on renewable energy resources

    Energy Technology Data Exchange (ETDEWEB)

    Rau, N S

    1994-08-01

    This report describes the state of the art of electric energy storage technologies and discusses how adding intermittent renewable energy technologies (IRETs) to a utility network affects the benefits from storage dispatch. Load leveling was the mode of storage dispatch examined in the study. However, the report recommended that other modes be examined in the future for kilowatt and kilowatt-hour optimization of storage. The motivation to install storage with IRET generation can arise from two considerations: reliability and enhancement of the value of energy. Because adding storage increases cost, reliability-related storage is attractive only if the accruing benefits exceed the cost of storage installation. The study revealed that the operation of storage should not be guided by the output of the IRET but rather by system marginal costs. Consequently, in planning studies to quantify benefits, storage should not be considered as an entity belonging to the system and not as a component of IRETS. The study also indicted that because the infusion of IRET energy tends to reduce system marginal cost, the benefits from load leveling (value of energy) would be reduced. However, if a system has storage, particularly if the storage is underutilized, its dispatch can be reoriented to enhance the benefits of IRET integration.

    Health insurance plans serve a critical role in public health emergencies, yet little has been published about their collective emergency preparedness practices and policies. We evaluated, on a national scale, the state of health insurance plans' emergency preparedness and policies. A survey of health insurance plans. We queried members of America's Health Insurance Plans, the national trade association representing the health insurance industry, about issues related to emergency preparedness issues: infrastructure, adaptability, connectedness, and best practices. Of 137 health insurance plans queried, 63% responded, representing 190.6 million members and 81% of US plan enrollment. All respondents had emergency plans for business continuity, and most (85%) had infrastructure for emergency teams. Some health plans also have established benchmarks for preparedness (eg, response time). Regarding adaptability, 85% had protocols to extend claim filing time and 71% could temporarily suspend prior medical authorization rules. Regarding connectedness, many plans shared their contingency plans with health officials, but often cited challenges in identifying regulatory agency contacts. Some health insurance plans had specific policies for assisting individuals dependent on durable medical equipment or home healthcare. Many plans (60%) expressed interest in sharing best practices. Health insurance plans are prioritizing emergency preparedness. We identified 6 policy modifications that health insurance plans could undertake to potentially improve healthcare system preparedness: establishing metrics and benchmarks for emergency preparedness; identifying disaster-specific policy modifications, enhancing stakeholder connectedness, considering digital strategies to enhance communication, improving support and access for special-needs individuals, and developing regular forums for knowledge exchange about emergency preparedness.

  18. On Emergent Physics, "Unparticles" and Exotic "Unmatter" States

    Full Text Available Emergent physics refers to the formation and evolution of collective patterns in systems that are nonlinear and out-of-equilibrium. This type of large-scale behavior often develops as a result of simple interactions at the component level and involves a dynamic interplay between order and randomness. On account of its universality, there are credible hints that emergence may play a leading role in the Tera-ElectronVolt (TeV sector of particle physics. Following this path, we examine the possibility of hypothetical high-energy states that have fractional number of quanta per state and consist of arbitrary mixtures of particles and antiparticles. These states are similar to "un-particles", massless fields of non-integral scaling dimensions that were recently conjectured to emerge in the TeV sector of particle physics. They are also linked to "unmatter", exotic clusters of matter and antimatter introduced few years ago in the context of Neutrosophy.

    We examined the manner in which state public health agencies have organized their operations to accomplish the goals associated with emergency preparedness (EP) funds. We also examined the leadership challenges associated with the effective utilization of preparedness funds. The websites of all 50 state public health organizations in the USA were examined in order to determine the different approaches that states have used to organize for preparedness. Thirty-eight states provided sufficient information to allow for classification of their organizational approach to EP. Telephone interviews were conducted with representatives in three model states to obtain deeper insights into the organizational approach. Three predominant organizational models were identified as a means to address the challenge of organizing for preparedness. The results confirmed the equifinality principle of organization (there may be more than one equally effective way to organize) and demonstrated that, contrary to the prescription of early management thought, there is no 'one best way' to organize. Leadership rather than formal management emerged as the primary contributor to perceived EP. Specifically, interviews with preparedness professionals indicated that they believed expert power was more important than position power and the ability to negotiate and influence through persuasion was more important than formal authority. All three models contained, to a greater or lesser degree, elements of matrix management with the associated leadership challenges for emergency preparedness (EP) directors. Recommendations were provided for successful leadership in the context of EP directors in state departments of public health.

    La Crosse encephalitis is a viral disease that has emerged in new locations across the Appalachian region of the United States. Conventional wisdom suggests that ongoing emergence of La Crosse virus (LACV) could stem from the invasive Asian tiger (Aedes albopictus) mosquito. Efforts to prove this, however, are complicated by the numerous transmission routes and species interactions involved in LACV dynamics. To analyze LACV transmission by Asian tiger mosquitoes, we constructed epidemiologic models. These models accurately predict empirical infection rates. They do not, however, support the hypothesis that Asian tiger mosquitoes are responsible for the recent emergence of LACV at new foci. Consequently, we conclude that other factors, including different invasive mosquitoes, changes in climate variables, or changes in wildlife densities, should be considered as alternative explanations for recent increases in La Crosse encephalitis.

    2015-02-01

    Midlevel providers, including physician assistants (PA), have been recommended by some to fill the current inadequate supply of providers nationally, including in emergency medicine. PA practice is governed by state law. We described the differences in qualifications, scope of practice, prescriptive authority, and physician supervision required by individual states for PA practice and describe the impact this may have on emergency medicine. A cross-sectional analysis of United States laws governing PA practice by abstraction from each state's public website. State characteristics were collected from the American Academy of Physician Assistants and United States Census websites and dichotomized by median values. Only six states (12%), all of which were larger-population states, required physician review of medical records within 1 week of a PA-only patient encounter. However, one state (Virginia) explicitly required onsite physician presence for PA practice in the emergency department. All states allowed PAs to assist in invasive procedures, but 13 (25%) restricted independent performance. Restriction of this practice was more likely in states with a higher population (38%), lower rural proportion (40%), and lower number of PAs per population (40%). Eleven (22%) states restricted performance of sedation or general anesthesia. An expanded scope of practice for disaster situations was allowed by 24 (47%) states and was more likely in larger population states (62%). All but two states (Florida and Kentucky) allowed PA prescribing of schedule III-V medications, and 37 (73%) allowed prescribing of schedule II medications. Laws governing PA practice in emergency departments differ by state, but generally allow for a broad scope of practice and limited direct supervision. Smaller, rural states were less likely to have tighter restrictions or oversight. Copyright © 2015 Elsevier Inc. All rights reserved.

  6. Emergence of advance waves in a steady-state universe

    Energy Technology Data Exchange (ETDEWEB)

    Hobart, R.H.

    1979-10-01

    In standard Wheeler-Feynman electrodynamics advanced waves from any source are absolutely canceled by the advanced waves from the absorber responding to that source. The present work shows this cancellation fails over cosmic distances in a steady-state universe. A test of the view proposed earlier, in a paper which assumed failure of cancellation ad hoc, that zero-point fluctuations of the electromagnetic field are such emergent advanced waves, is posed. The view entails anomalous slowing of spontaneous transition rates at longer emission wavelengths; available data go against this, furnishing additional argument against the suspect assumption that the universe is steady-state.

    The first Administration-wide Quadrennial Energy Review (QER), released in April 2015, found that the “interacting and overlapping” division of authority between “federal, regional and state institutions and regulatory structures” for the electricity sector could “impede development of the grid of the future [and] . . . the development of markets that efficiently integrate” new and emerging technologies.1 While “technology is indifferent to state-Federal boundaries and jurisdictions,” the QER explained, “technology users cannot be.”2 The report concluded that “[b]oth Federal and state governments need to play constructive and collaborative roles in the future to ensure that consumers and industry are able to maximize the value of new technologies.”3 The QER recommended that the Department of Energy (“DOE”) facilitate such collaboration by playing a “convening role” to bring together state and federal regulators and other stakeholders to consider these issues.4 This paper provides background and analysis on these jurisdictional issues and the impact they may have on adoption of emerging energy technologies and coordination of markets for those technologies, in support of future dialogs on these subjects. In particular, this paper reviews the structure of the Federal Power Act (“FPA”),5 and compares the division of authority between the federal and state governments adopted there with other federal energy and energy-related statutes.

    Workshops were conducted in 5 cities to improve communications between the states and the Federal government so that both might be better prepared to avoid or mitigate the impacts of energy emergencies during the winter; to provide a forum for the exchange of technical information regarding selected energy demand restraint measures which could be implemented by individual states or regions in an energy emergency; and to promote the concept of pre-crisis contingency planning and strategy development, with particuliar emphasis on the need for interstate coordination of emergency plans. The major topics addressed by the discussion guide involved net energy use impact, implementation procedures and problems, and social and economic effects. The Task Force performed extensive research into the technical considerations and prior experience in implementing each of the demand restraint measures selected for discussion. Results and conclusions are summarized for reduction of thermostat setting for space conditioning and water heating; reduction in hours of operation and lighting in commercial establishments; reduction in hours of operation in school, and industrial fuel substitution.

    The interest in biomass fuel is continuing to expand globally and in the northeastern United States as wood pellets are becoming a primary source of fuel for residential and small commercial systems. Wood pellets for boilers are often stored in basement storage rooms or large bag-type containers. Due to the enclosed nature of these storage areas, the atmosphere may exhibit increased levels of carbon monoxide. Serious accidents in Europe have been reported over the last decade in which high concentrations of carbon monoxide (CO) have been found in or near bulk pellet storage containers. The aim of this study was to characterize the CO concentrations in areas with indoor storage of bulk wood pellets. Data was obtained over approximately 7 months (December 2013 to June 2014) at 25 sites in New Hampshire and Massachusetts: 16 homes using wood pellet boilers with indoor pellet storage containers greater than or equal to 3 ton capacity; 4 homes with wood pellet heating systems with outdoor pellet storage; 4 homes using other heating fuels; and a university laboratory site. CO monitors were set up in homes to collect concentrations of CO in the immediate vicinity of wood pellet storage containers, and data were then compared to those of homes using fossil fuel systems. The homes monitored in this study provided a diverse set of housing stock spanning two and a half centuries of construction, with homes built from 1774 to 2013, representing a range of air exchange rates. The CO concentration data from each home was averaged hourly and then compared to a threshold of 9 ppm. While concentrations of CO were generally low for the homes studied, the need to properly design storage locations for pellets is and will remain a necessary component of wood pellet heating systems to minimize the risk of CO exposure. This paper is an assessment of carbon monoxide (CO) exposure from bulk wood pellet storage in homes in New Hampshire and Massachusetts. Understanding the CO concentrations

    The historical precedents that support state and local leadership in preparedness for and response to disasters are in many ways at odds with the technical demands of preparedness and response for incidents affecting public health. New and revised laws and regulations, executive orders, policies, strategies, and plans developed in response to biological threats since 2001 address the role of the federal government in the response to public health emergencies. However, financial mechanisms for disaster response-especially those that wait for gubernatorial request before federal assistance can be provided-do not align with the need to prevent the spread of infectious agents or efficiently reduce the impact on public health. We review key US policies and funding mechanisms relevant to public health emergencies and clarify how policies, regulations, and resources affect coordinated responses.

    2015-01-01

    NASA's Marshall Space Flight Center has developed a solid-state ultracapacitor using a novel nanocomposite, dielectric material. The material's design is based on the internal barrier layer capacitance (IBLC) concept, and it uses novel dielectric and metallic conductive ink formulations. Novel processing methods developed by NASA provide for unique dielectric properties at the grain level. Nanoscale raw material powders are tailored using a variety of techniques and then formulated into a special ink. This dielectric ink is used with novel metallic conductive ink to print a capacitor layer structure into any design necessary to meet a range of technical requirements. The innovation is intended to replace current range safety batteries that NASA uses to power the systems that destroy off-course space vehicles. A solid-state design provides the needed robustness and safety for this demanding application.

    Introduction Little is known about the existence, distribution, and characteristics of Emergency Medical Services (EMS) systems in Africa, or the corresponding epidemiology of prehospital illness and injury. A survey was conducted between 2013 and 2014 by distributing a detailed EMS system questionnaire to experts in paper and electronic versions. The questionnaire ascertained EMS systems' jurisdiction, operations, finance, clinical care, resources, and regulatory environment. The discovery of respondents with requisite expertise occurred in multiple phases, including snowball sampling, a review of published scientific literature, and a rigorous search of the Internet. The survey response rate was 46%, and data represented 49 of 54 (91%) African countries. Twenty-five EMS systems were identified and distributed among 16 countries (30% of African countries). There was no evidence of EMS systems in 33 (61%) countries. A total of 98,574,731 (8.7%) of the African population were serviced by at least one EMS system in 2012. The leading causes of EMS transport were (in order of decreasing frequency): injury, obstetric, respiratory, cardiovascular, and gastrointestinal complaints. Nineteen percent of African countries had government-financed EMS systems and 26% had a toll-free public access telephone number. Basic emergency medical technicians (EMTs) and Basic Life Support (BLS)-equipped ambulances were the most common cadre of provider and ambulance level, respectively (84% each). Emergency Medical Services systems exist in one-third of African countries. Injury and obstetric complaints are the leading African prehospital conditions.

    1978-01-01

    Using a special analytical procedure for tracking and assessing events reported in the nation's newspapers, the Center for Policy Process has identified ten emerging trends in the United States that are having a major impact on all our lives and on all businesses and industries--and especially on the electric utility industry. Although the trends may move in contradictory directions and have different degrees of significance, all have been carefully monitored for a considerable length of time. All are firmly established--and are not to be viewed as the momentary interests of certain radical elements of the population. The ten trends are: the fast-emerging clash between nuclear fuel and coal as an environmental health issue; displacement of racism and sexism by ''ageism'' as society's most prominent anti-discrimination preoccupation, and the complete elimination soon of mandatory retirement; in government and technology, the phenomenon of ''appropriate scale'' replacing economies of scale, emergence of single-issue political organizations; coming-of-age of the recycling ethic; emergence of ''access to capital'' as the new equity issue--the new rights issue; continuing shift from centralization to decentralization; movement of society in the dual directions of high technology/high touch; business' increasing involvement with the well-established accountability trend; and shift from a representative democracy to a participatory democracy--this profound change in American democracy actually began about a decade or so ago.

  1. Evaluation of chlorine dispersion from storage unit in a petrochemical complex to providing an emergency response program

    Full Text Available Background and aims  Chlorine gas is a dangerous material that is used in chemical industries. In spite of the attempts for chlorine gas release control, sudden releases still occur in the related installations. Not taking proper emergency measures after chlorine gas dispersion may result in serious harm to health of the personnel and the people residing around the industrial area. The present study considers chlorine gas dispersion scenarios, determines emergency levels and presents an optimized pattern for more effective and faster response with the least required measures for emergency conditions control.   Methods   In the present paper by using Hazard and Operability Study (HAZOP and risk matrix the possible scenarios of chlorine gas dispersion in storage tanks unit of a petrochemical complex were considered. Then the intervals of these scenarios were determined with a view to Emergency Response Planning Guideline 1-2-3. With a view to the intensity of pollution extension and the population exposed to risk the scenarios were classified in the four emergency levels defined by Center for Chemical Process Safety (CCPS. Finally for each class of scenarios with a view to the related emergency level an optimum pattern of response plan in emergency conditions was presented.   Results  On the basis of the results of this study, chlorine gas dispersion scenario of the catastrophic explosion of the tank and scrubber system failure in the summer was classified in emergency level 4, in the winter in emergency level 3, chlorine gas dispersion due to chlorine lines rupture in the summer and winter in emergency level 3 and chlorine gas dispersion due to leakage of flanges and gaskets in emergency level 2 according to emergency levels of CCPS.  Conclusion The results of this study showed that systematic process risks analysis by use of risks recognition methods such as HAZOP and consequence analysis may have an effective role in recognition of the

    Changes in the quality of frozen mango cuboids were investigated during long-term glassy state storage with and without osmotic dehydration pretreatment. The mango cuboids were dehydrated in mixed solutions (sucrose: glucose: fructose in a ratio of 3.6:1:3) of different concentrations (30, 40, and 50% (wt/wt)) prior to freezing and then stored at -55 °C (in the glassy state) for 6 months. The results revealed that compared with the untreated samples, osmotic pretreatment decreased total color difference (reduced by 15.6-62.3%), drip loss (reduced by 8.2-29.5%) and titration acidity (reduced by 1.3-9.4%), while increasing hardness (increased by 48.8-82.3%), vitamin C content (increased by 72.5-120.6%) and total soluble solids (increased by 21.8-53.7%) of frozen mangoes after 6 months. Dehydration with a sugar concentration of 40% was considered as the optimal pretreatment condition. In addition, a storage temperature of -55 °C provided better retention of quality than rubbery state storage at -18 °C. With prolonged storage time, the quality of frozen mangoes continued to change, even in the glassy state. However, the changes in quality of the osmotic-dehydrated samples were less than those of the untreated samples. The current work indicates that osmotic pretreatment and glassy state storage significantly improved the quality of frozen mangoes during long-term storage.

  4. Storage battery operation technique of photovoltaic system to prevent the imbalance of state of charge

    Science.gov (United States)

    Kobayashi, Hirotake; Takigawa, Kiyoshi; Takeda, Yukihiro

    For the large scale storage battery system of a MW class photovoltaic system, simulation analyses were conducted to prevent the imbalance of state of charge. Effects of the charge and discharge I-V characteristics dispersion of individual storage battery on the dispersion of state of charge were elucidated through these analyses. Furthermore, a proper operation method to prevent the imbalance of state of charge was investigated. In the internal resistance and the electromotive voltage which determines the charge and discharge I-V characteristics, when the dispersion is found in the electromotive voltage in particular, the dispersion of state of charge gets larger. The electromotive voltage of storage battery depends on the specific gravity of electrolyte. Consequently, in order to prevent the imbalance of state of charge, it is important to control the specific gravity. For operating the system effectively preventing the imbalance of state of charge, the specific gravity should be controlled within (+ or -) 0.3 percent of approximate mean value.

    In the current industrial scenario there is a serious need for formulating strategies to handle hazardous substances in the safest way. Manufacture, storage, and use of hazardous substances pose a serious risk to industry, people, and the environment. Accidental release of toxic chemicals can lead to emergencies. An emergency response plan (ERP) is inevitable to minimize the adverse effects of such releases. The on-site emergency plan is an integral component of any process safety and risk management system. This paper deals with an on-site emergency response plan for a chlorine manufacturing industry. It was developed on the basis of a previous study on chlorine release and a full scale mock drill has been conducted for testing the plan. Results indicated that properly trained personnel can effectively handle each level of incidents occurring in the process plant. As an extensive guideline to the district level government authorities for off-site emergency planning, risk zone has also been estimated with reference to a chlorine exposure threshold of 3 ppm.

    Although the use of resilience skills (RSs) by emergency department (ED) front-line staff is ubiquitous, the nature and origin of these skills tend to be taken for granted. This study investigates the research question "where do RSs come from"? Case studies in two EDs were undertaken in order to answer the research question: one in Brazil and the other in the United States. The case studies adopted the same data collection and analysis procedures, involving interviews, questionnaires, observations, and analysis of documents. A model for describing RSs as emergent phenomena is proposed. The model indicates that RSs arise from interactions between: work constraints, hidden curriculum, gaps in standardized operating procedures, organizational support for resilience, and RSs themselves. An instantiation of the model is illustrated by a critical event identified from the American ED. The model allows the identification of leverage points for influencing the development of RSs, instead of leaving their evolution purely to chance. Copyright © 2016 Elsevier Ltd.

    2003-01-01

    The optical absorption spectra of BaF sub 2 sub - sub x Cl sub x :Eu in different states of optical storage were measured to clarify the electron trapping mechanism for its optical storage and photo-stimulated luminescence (PSL). Based on the absorption spectra and difference absorption spectra, the electron transfer processes after ultraviolet (UV) light irradiation were investigated. This demonstrates that (1) Eu sup 3 sup + ions are formed upon UV light irradiation at room temperature; (2) the two absorption bands in the visible region (400-600 nm) should be assigned to two different F centres, both of which contribute to the optical storage and PSL, and (3) a third broad difference absorption band around approx 650 nm, which matches the common laser better, was observed.

    Among many types of nanostructured inorganic materials, highly anisotropic 2D nanosheets provide unique advantages in designing and synthesizing efficient electrode and electrocatalyst materials for novel energy storage technologies. 2D inorganic nanosheets boast lots of unique characteristics such as high surface area, short ion diffusion path, tailorable compositions, and tunable electronic structures. These merits of 2D inorganic nanosheets render them promising candidate materials as electrodes for diverse secondary batteries and supercapacitors, and electrocatalysts. A wide spectrum of examples is presented for inorganic nanosheet-based electrodes and electrocatalysts. Future perspectives in research about 2D nanosheet-based functional materials are discussed to provide insight for the development of next-generation energy storage systems using 2D nanostructured materials. © 2018 Wiley-VCH Verlag GmbH & Co.

    Energy storage technology has received significant attention for portable electronic devices, electric vehicle propulsion, bulk electricity storage at power stations, and load leveling of renewable sources, such as solar energy and wind power. Lithium ion batteries have dominated most of the first two applications. For the last two cases, however, moving beyond lithium batteries to the element that lies below-sodium-is a sensible step that offers sustainability and cost-effectiveness. This requires an evaluation of the science underpinning these devices, including the discovery of new materials, their electrochemistry, and an increased understanding of ion mobility based on computational methods. The Review considers some of the current scientific issues underpinning sodium ion batteries. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Introduction: Ready-to-eat (RTE) leafy vegetables have a natural leaf microbiota that changes during different processing and handling steps from farm to fork. The objectives of this study were (i) to compare the microbiota of RTE baby spinach and mixed-ingredient salad before and after seven days of storage at 8°C or 15°C; (ii) to explore associations between bacterial communities and the foodborne pathogens Listeria monocytogenes, pathogenic Yersinia enterocolitica, and pathogen model organism Escherichia coli O157:H7 gfp+ when experimentally inoculated into the salads before storage; and (iii) to investigate if bacterial pathogens may be detected in the 16S rRNA amplicon dataset. Material and methods: The microbiota was studied by means of Illumina 16S rRNA amplicon sequencing. Subsets of samples were inoculated with low numbers (50-100 CFU g-1) of E. coli O157:H7 gfp+, pathogenic Y. enterocolitica or L. monocytogenes before storage. Results and discussion: The composition of bacterial communities changed during storage of RTE baby spinach and mixed-ingredient salad, with Pseudomonadales as the most abundant order across all samples. Although pathogens were present at high viable counts in some samples, they were only detected in the community-wide dataset in samples where they represented approximately 10% of total viable counts. Positive correlations were identified between viable counts of inoculated strains and the abundance of Lactobacillales, Enterobacteriales, and Bacillales, pointing to positive interactions or similar environmental driver variables that may make it feasible to use such bacterial lineages as indicators of microbial health hazards in leafy vegetables. The data from this study contribute to a better understanding of the bacteria present in RTE salads and may help when developing new types of biocontrol agents.​.

    The quality and safety of maize (Zea mays L.) from different grain storage units (GSUs), located in the main producing region of Rondonia State (RO), Northern Brazil were evaluated. Maize grains (n= 76) stored in four GSUs were collected from July to November 2014 and evaluated for grain damages, humidity, fungi and fumonisins (FBs) content. The climate conditions data were also obtained from plant growing to storage periods. Regarding the moisture content and water activity, these varied from 10.0 to 16.1% and 0.5 to 0.8, respectively. As expected, fungi spores were present in 94.8% of the samples, prevailing Fusarium genera, with a fungi colony maximum of 2.2x104 CFU g-1. Regarding FBs, 60.5% of the samples were contaminated, below Brazilian and United States maximum limits, but 9.2% had levels higher than the European legislation.

    This review aims to update knowledge about Ebola virus disease (EVD) and recent advances in its diagnosis, treatment and prevention. A literature review was performed using the following databases: ISI Web of Knowledge, PubMed, IRIS, Scopus and the websites of the CDC and the WHO. Additionally, we have included articles and reports referenced in the basic literature search, and news that were considered relevant. The Ebola virus, endemic in some parts of Africa, is responsible for a severe form of hemorrhagic fever in humans; bats are probably its natural reservoir. It is an extremely virulent virus and easily transmitted by bodily fluids. EVD's complex pathophysiology, characterized by immunosuppression as well as stimulation of an intense inflammatory response, results in a syndrome similar to septic shock. The diagnosis is difficult due to the initial symptoms that mimic other diseases. Despite the high mortality rates that can amount to 90%, a prophylaxis (chemical or vaccine) or effective treatment does not exist. Two vaccines and experimental therapies are being developed for the prevention and treatment of EVD. Although the virus is known for about 40 years, the lack of knowledge obtained and the disinterest of government authorities in the countries involved justify the state of emergency currently exists regarding this infectious agent. Only the coordination of multiple entities and the effective commitment of the international community will facilitate the control and effective prevention of EVD.

    The objective of this article is to determine the monthly variation of emergency department (ED) visits for pediatric headache. We hypothesized youth have increased headache-related ED visits in the months associated with school attendance. Using a United States representative sample of ED visits in the National Hospital Ambulatory Medical Care Survey from 1997 to 2009, we estimated number of visits associated with ICD-9 codes related to headache, migraine, status migrainosus, or tension-type headache in 5- to 18-year-olds. Age-stratified multivariate models are presented for month of visit (July as reference). There was a national estimate of 250,000 ED visits annually related to headache (2.1% of total visits) in 5- to 18-year-olds. In 5- to 11-year-olds, the adjusted rate of headache-related visits was lower in April (OR 0.42, 95% CI 0.20, 0.88). In 12- to 18-year-olds, there were higher rates in January (OR 1.92, 95% CI 1.16, 3.14) and September (OR 1.64, 95% CI 1.06, 2.55). In adolescents we found higher ED utilization in January and September, the same months associated with school return from vacation for a majority of children nationally. No significant reduction in the summer suggests that school itself is not the issue, but rather changes in daily lifestyle and transitions.

    Since 1989, several states have passed laws that make gun owners criminally liable if someone is injured because a child gains unsupervised access to a gun. These laws are controversial, and their effect on firearm-related injuries is unknown. To determine if state laws that require safe storage of firearms are associated with a reduction in child mortality due to firearms. An ecological study of firearm mortality from 1979 through 1994. All 50 states and the District of Columbia. All children younger than 15 years. Unintentional deaths, suicides, and homicides due to firearms. Laws that make gun owners responsible for storing firearms in a manner that makes them inaccessible to children were in effect for at least 1 year in 12 states from 1990 through 1994. Among children younger than 15 years, unintentional shooting deaths were reduced by 23% (95% confidence interval, 6%-37%) during the years covered by these laws. This estimate was based on within-state comparisons adjusted for national trends in unintentional firearm-related mortality. Gun-related homicide and suicide showed modest declines, but these were not statistically significant. State safe storage laws intended to make firearms less accessible to children appear to prevent unintentional shooting deaths among children younger than 15 years.

    Prior studies suggesting that the presence of emergency department (ED) observation units decrease overall ED hospital admissions have been either single-center studies or based on model simulations. The objective of this preliminary national study is to determine if the presence of ED observation units is associated with hospitals having lower ED admission rates. We conducted a retrospective cross-sectional analysis using the 2010 National Hospital Ambulatory Care Survey and estimated ED risk-standardized hospital admission rates (RSHAR) for each center. The following were excluded from the study: ages unit status were also excluded. We used linear regression analysis to determine the association between ED RSHAR and presence of observation units. There were 24,232 ED visits in 315 hospitals in the United States. Of these, 82 (20.6%) hospitals had an ED observation unit. The average ED risk-standardized hospital admission rates for hospitals with observation units and without hospital observation units were 13.7% (95% confidence interval [CI]: 11.3-16.0) and 16.0% (95% CI: 14.1-17.7), respectively. The difference of 2.3% was not statistically significant. In this preliminary study, we did not find an association between the presence of observation units and ED hospital admission rates. Further studies with larger sample sizes should be performed to further evaluate the impact of ED observation units on ED hospital admission rates. © 2015 Society of Hospital Medicine.

    Synchrotrons and storage rings deliver radiation across the electromagnetic spectrum at high repetition rates, and free electron lasers (FELs) produce radiation pulses with high peak brightness. However, at present few light sources can generate both high repetition rate and high brightness outside the optical range. We propose to create steady-state microbunching (SSMB) in a storage ring to produce coherent radiation at a high repetition rate or in continuous wave (CW) mode. In this paper we describe a general mechanism for producing SSMB and give sample parameters for EUV lithography and sub-millimeter sources. We also describe a similar arrangement to produce two pulses with variable spacing for pump-probe experiments. With technological advances, SSMB could reach the soft X-ray range (< 10 nm).

    The Institute of Medicine (IOM)'s "Future of Emergency Care" report recommended the categorization and regionalization of emergency care, but no uniform system to categorize hospital emergency care capabilities has been developed. The absence of such a system limits the ability to benchmark outcomes, to develop regional systems of care, and of patients to make informed decisions when seeking emergency care. The authors sought to pilot the deployment of an emergency care categorization system in two states. A five-tiered emergency department (ED) categorization system was designed, and a survey of all Pennsylvania and Wisconsin EDs was conducted. This 46-item survey described hospital staffing, characteristics, resources, and practice patterns. Based on responses, EDs were categorized as limited, basic, advanced, comprehensive, and pediatric critical care capable. Prehospital transport times were then used to determine population access to each level of care. A total of 247 surveys were received from the two states (247 of 297, 83%). Of the facilities surveyed, roughly one-quarter of hospitals provided advanced care, 10.5% provided comprehensive care, and 1.6% provided pediatric critical care. Overall, 75.1% of the general population could reach an advanced or comprehensive ED within 60 minutes by ground transportation. Among the pediatric population (age 14 years and younger), 56.2% could reach a pediatric critical care or comprehensive ED, with another 19.5% being able to access an advanced ED within 60 minutes. Using this categorization system, fewer than half of all EDs provide advanced or comprehensive emergency care. While the majority of the population has access to advanced or comprehensive care within an hour, a significant portion (25%) does not. This article describes how an ED categorization scheme could be developed and deployed across the United States. There are implications for prehospital planning, patient decision-making, outcomes measurement

    Full Text Available The Democratic Republic of Congo (DRC is the second largest country on the African continent with a population of over 70 million. It is also a major crossroad through Africa as it borders nine countries. Unfortunately, the DRC has experienced recurrent political and social instability throughout its history and active fighting is still prevalent today. At least two decades of conflict have devastated the civilian population and collapsed healthcare infrastructure. Life expectancy is low and government expenditure on health per capita remains one of the lowest in the world. Emergency Medicine has not been established as a specialty in the DRC. While the vast majority of hospitals have emergency rooms or salle des urgences, this designation has no agreed upon format and is rarely staffed by doctors or nurses trained in emergency care. Presenting complaints include general and obstetric surgical emergencies as well as respiratory and diarrhoeal illnesses. Most patients present late, in advanced stages of disease or with extreme morbidity, so mortality is high. Epidemics include HIV, cholera, measles, meningitis and other diarrhoeal and respiratory illnesses. Lack of training, lack of equipment and fee-for-service are cited as barriers to care. Pre-hospital care is also not an established specialty. New initiatives to improve emergency care include training Congolese physicians in emergency medicine residencies and medic ranger training within national parks.

    Integrated Multi-mission Ground Segment for Earth Observation Satellites (IMGEOS) was established with an objective to eliminate human interaction to the maximum extent. All emergency data products will be delivered within an hour of acquisition through FTP delivery. All other standard data products will be delivered through FTP within a day. The IMGEOS activity was envisaged to reengineer the entire chain of operations at the ground segment facilities of NRSC at Shadnagar and Balanagar campuses to adopt an integrated multi-mission approach. To achieve this, the Information Technology Infrastructure was consolidated by implementing virtualized tiered storage and network computing infrastructure in a newly built Data Centre at Shadnagar Campus. One important activity that influences all other activities in the integrated multi-mission approach is the design of appropriate storage and network architecture for realizing all the envisaged operations in a highly streamlined, reliable and secure environment. Storage was consolidated based on the major factors like accessibility, long term data protection, availability, manageability and scalability. The broad operational activities are reception of satellite data, quick look, generation of browse, production of standard and valueadded data products, production chain management, data quality evaluation, quality control and product dissemination. For each of these activities, there are numerous other detailed sub-activities and pre-requisite tasks that need to be implemented to support the above operations. The IMGEOS architecture has taken care of choosing the right technology for the given data sizes, their movement and long-term lossless retention policies. Operational costs of the solution are kept to the minimum possible. Scalability of the solution is also ensured. The main function of the storage is to receive and store the acquired satellite data, facilitate high speed availability of the data for further

    Triage, as it is understood in the context of the emergency department, is the first and perhaps the most formal stage of the initial patient encounter. Bottlenecks during intake and long waiting room times have been linked to higher rates of patients leaving without being seen. The solution in many emergency departments has been to collect less information at triage or use an "immediate bedding" or "pull until full" approach, in which patients are placed in treatment areas as they become available without previous screening. The purpose of this study was to explore emergency nurses' understanding of-and experience with-the triage process, and to identify facilitators and barriers to accurate acuity assignation. An exploratory qualitative study using focus-group interviews (N = 26). Five themes were identified: (1) "Sick or not sick," (2) "Competency/qualifications," (3) "Triaging the emergency department, not the patient," (4) "The unexpected," and (5) "Barriers and facilitators." Our participants described processes that were unit- and/or nurse-dependent and were manipulations of the triage system to "fix" problems in ED flow, rather than a standard application of a triage system. Our participants reported that, in practice, the use of triage scales to determine acuity and route patients to appropriate resources varies in accuracy and application among emergency nurses and in their respective emergency departments. Nurses in this sample reported a prevalence of "quick look" triage approaches that do not rely on physiologic data to make acuity decisions. Future research should focus on intervention and comparison studies examining the effect of staffing, nurse experience, hospital policies, and length of shift on the accuracy of triage decision making.

    As fewer surgeons take emergency general surgery call and hospitals decrease emergency services, a crisis in access looms in the United States. We examined national emergency general surgery capacity and county-level determinants of access to emergency general surgery care with special attention to disparities. To identify potential emergency general surgery hospitals, we queried the database of the American Hospital Association for "acute care general hospital," with "surgical services," and "emergency department," and ≥1 "operating room." Internet search and direct contact confirmed emergency general surgery services that covered the emergency room 7 days a week, 24 hours a day. Geographic and population-level emergency general surgery access was derived from Geographic Information Systems and US Census. Of the 6,356 hospitals in the 2013 American Hospital Association database, only 2,811 were emergency general surgery hospitals. Counties with greater percentages of black, Hispanic, uninsured, and low-education individuals and rural counties disproportionately lacked access to emergency general surgery care. For example, counties above the 75th percentile of African American population (10.2%) had >80% odds of not having an emergency general surgery hospital compared with counties below the 25th percentile of African American population (0.6%). Gaps in access to emergency general surgery services exist across the United States, disproportionately affecting underserved, rural communities. Policy initiatives need to increase emergency general surgery capacity nationwide. Copyright © 2017 Elsevier Inc. All rights reserved.

    1983-11-01

    A set of solid state phase change materials was evaluated for possible use in passive solar thermal energy storage systems. The most promising materials are organic solid solutions of pentaerythritol, pentaglycerine and neopentyl glycol. Solid solution mixtures of these compounds can be tailored so that they exhibit solid-to-solid phase transformations at any desired temperature within the range from less than 25 deg to 188 deg. Thermophysical properties such as thermal conductivity, density and volumetric expansion were measured. Computer simulations were used to predict the performance of various Trombe wall designs incorporating solid state phase change materials. Optimum performance was found to be sensitive to the choice of phase change temperatures and to the thermal conductivity of the phase change material. A molecular mechanism of the solid state phase transition is proposed and supported by infrared spectroscopic evidence.

    A homogeneous ferroelectric single crystal exhibits only two remanent polarization states that are stable over time, whereas intermediate, or unsaturated, polarization states are thermodynamically instable. Commonly used ferroelectric materials however, are inhomogeneous polycrystalline thin films or ceramics. To investigate the stability of intermediate polarization states, formed upon incomplete, or partial, switching, we have systematically studied their retention in capacitors comprising two classic ferroelectric materials, viz. random copolymer of vinylidene fluoride with trifluoroethylene, P(VDF-TrFE), and Pb(Zr,Ti)O3. Each experiment started from a discharged and electrically depolarized ferroelectric capacitor. Voltage pulses were applied to set the given polarization states. The retention was measured as a function of time at various temperatures. The intermediate polarization states are stable over time, up to the Curie temperature. We argue that the remarkable stability originates from the coexistence of effectively independent domains, with different values of polarization and coercive field. A domain growth model is derived quantitatively describing deterministic switching between the intermediate polarization states. We show that by using well-defined voltage pulses, the polarization can be set to any arbitrary value, allowing arithmetic programming. The feasibility of arithmetic programming along with the inherent stability of intermediate polarization states makes ferroelectric materials ideal candidates for multibit data storage.

  18. A national perspective on paleoclimate streamflow and water storage infrastructure in the conterminous United States

    Science.gov (United States)

    Ho, Michelle; Lall, Upmanu; Sun, Xun; Cook, Edward

    2017-04-01

    Large-scale water storage infrastructure in the Conterminous United States (CONUS) provides a means of regulating the temporal variability in water supply with storage capacities ranging from seasonal storage in the wetter east to multi-annual and decadal-scale storage in the drier west. Regional differences in water availability across the CONUS provides opportunities for optimizing water dependent economic activities, such as food and energy production, through storage and transportation. However, the ability to sufficiently regulate water supplies into the future is compromised by inadequate monitoring of non-federally-owned dams that make up around 97% of all dams. Furthermore, many of these dams are reaching or have exceeded their economic design life. Understanding the role of dams in the current and future landscape of water requirements in the CONUS is needed to prioritize dam safety remediation or identify where redundant dams may be removed. A national water assessment and planning process is needed for addressing water requirements, accounting for regional differences in water supply and demand, and the role of dams in such a landscape. Most dams in the CONUS were designed without knowledge of devastating floods and prolonged droughts detected in multi-centennial paleoclimate records, consideration of projected climate change, nor consideration of optimal operation across large-scale regions. As a step towards informing water supply across the CONUS we present a paleoclimate reconstruction of annual streamflow across the CONUS over the past 555 years using a spatially and temporally complete paleoclimate record of summer drought across the CONUS targeting a set of US Geological Survey streamflow sites. The spatial and temporal structures of national streamflow variability are analyzed using hierarchical clustering, principal component analysis, and wavelet analyses. The reconstructions show signals of contemporary droughts such as the Dust Bowl (1930s

    Full Text Available This paper provides the first nationally representative estimates for use of four emerging products. Addressing the issue of land-line substitution with cell phones, we used a mixed-mode survey to obtain two representative samples of US adults. Of 3,240 eligible respondents contacted, 74% completed surveys. In the weighted analysis, 13.6% have tried at least one emerging tobacco product; 5.1% snus; 8.8% waterpipe; 0.6% dissolvable tobacco products; 1.8% electronic nicotine delivery systems (ENDS products. Daily smokers (25.1% and nondaily smokers (34.9% were the most likely to have tried at least one of these products, compared to former smokers (17.2% and never smokers (7.7%, P24 have tried one of these products, P<.01. In multivariable analysis, current daily (5.5, 4.3–7.6, nondaily (6.1, 4.0–9.3, and former smoking status (2.7, 2.1–3.6 remained significant, as did young adults (2.2, 1.6–3.0; males (3.5, 2.8–4.5; higher educational attainment; some college (2.7, 1.7–4.2; college degree (2.0, 1.3–3.3. Use of these products raises concerns about nonsmokers being at risk for nicotine dependence and current smokers maintaining their dependence. Greater awareness of emerging tobacco product prevalence and the high risk demographic user groups might inform efforts to determine appropriate public health policy and regulatory action.

    The research described in this article was performed to develop a more complete picture of how hospital emergency departments (EDs) contribute to the U.S. health care system, which is currently evolving in response to economic, clinical, and political pressures. Using a mix of quantitative and qualitative methods, it explores the evolving role that EDs and the personnel who staff them play in evaluating and managing complex and high-acuity patients, serving as the key decisionmaker for roughly half of all inpatient hospital admissions, and serving as "the safety net of the safety net" for patients who cannot get care elsewhere. The report also examines the role that EDs may soon play in either contributing to or helping to control the rising costs of health care.

    2016-06-01

    Mobile prehospital care is a key component of emergency care. The aim of this study was to analyze the implementation of the State of Rio de Janeiro's Mobile Emergency Medical Service (SAMU, acronym in Portuguese). The methodology employed included document analysis, visits to six SAMU emergency call centers, and semistructured interviews conducted with 12 local and state emergency care coordinators. The study's conceptual framework was based on Giddens' theory of structuration. Intergovernmental conflicts were observed between the state and municipal governments, and between municipal governments. Despite the shortage of hospital beds, the SAMUs in periphery regions were better integrated with the emergency care network than the metropolitan SAMUs. The steering committees were not very active and weaknesses were observed relating to the limited role played by the state government in funding, management, and monitoring. It was concluded that the SAMU implementation process in the state was marked by political tensions and management and coordination weaknesses. As a result, serious drawbacks remain in the coordination of the SAMU with the other health services and the regionalization of emergency care in the state.

  15. An emerging network storage management standard: Media error monitoring and reporting information (MEMRI) - to determine optical tape data integrity

    Podio, Fernando; Vollrath, William; Williams, Joel; Kobler, Ben; Crouse, Don

    1998-01-01

    Sophisticated network storage management applications are rapidly evolving to satisfy a market demand for highly reliable data storage systems with large data storage capacities and performance requirements. To preserve a high degree of data integrity, these applications must rely on intelligent data storage devices that can provide reliable indicators of data degradation. Error correction activity generally occurs within storage devices without notification to the host. Early indicators of degradation and media error monitoring 333 and reporting (MEMR) techniques implemented in data storage devices allow network storage management applications to notify system administrators of these events and to take appropriate corrective actions before catastrophic errors occur. Although MEMR techniques have been implemented in data storage devices for many years, until 1996 no MEMR standards existed. In 1996 the American National Standards Institute (ANSI) approved the only known (world-wide) industry standard specifying MEMR techniques to verify stored data on optical disks. This industry standard was developed under the auspices of the Association for Information and Image Management (AIIM). A recently formed AIIM Optical Tape Subcommittee initiated the development of another data integrity standard specifying a set of media error monitoring tools and media error monitoring information (MEMRI) to verify stored data on optical tape media. This paper discusses the need for intelligent storage devices that can provide data integrity metadata, the content of the existing data integrity standard for optical disks, and the content of the MEMRI standard being developed by the AIIM Optical Tape Subcommittee.

  16. Low temperature thermal energy storage: a state-of-the-art survey

    Baylin, F.

    1979-07-01

    The preliminary version of an analysis of activities in research, development, and demonstration of low temperature thermal energy storage (TES) technologies having applications in renewable energy systems is presented. Three major categories of thermal storage devices are considered: sensible heat; phase change materials (PCM); and reversible thermochemical reactions. Both short-term and annual thermal energy storage technologies based on prinicples of sensible heat are discussed. Storage media considered are water, earth, and rocks. Annual storage technologies include solar ponds, aquifers, and large tanks or beds of water, earth, or rocks. PCM storage devices considered employ salt hydrates and organic compounds. The sole application of reversible chemical reactions outlined is for the chemical heat pump. All program processes from basic research through commercialization efforts are investigated. Nongovernment-funded industrial programs and foreign efforts are outlined as well. Data describing low temperature TES activities are presented also as project descriptions. Projects for all these programs are grouped into seven categories: short-term sensible heat storage; annual sensible heat storage; PCM storage; heat transfer and exchange; industrial waste heat recovery and storage; reversible chemical reaction storage; and models, economic analyses, and support studies. Summary information about yearly funding and brief descriptions of project goals and accomplishments are included.

  17. Storage on the vigor and viability of macauba seeds from two provenances of Minas Gerais State

    Directory of Open Access Journals (Sweden)

    Patrícia Pereira de Souza

    Full Text Available ABSTRACT: Macauba palm stands out for having favorable features to biodiesel production such as the high oil content of its fruit. Considering the great potential of the species and their applicability in the renewable energy field, it becomes indispensable to establish the right conditions for storing the seeds for propagation purpose. The aim of this research was to evaluate the effect of seed moisture content, packaging, and storage conditions such as temperature and relative humidity on the quality of seeds from Minas Gerais State, during a 12-month storage period. The research had two independent assays: (I the seeds were stored with three moisture contents/ranges 4.0≤6.0%; 6.0≤8.0% and 8.0≤10.0% in impermeable packages, under room temperature and at 10ºC; (II seeds with approximately 5.9% of moisture content were stored in three different types of packages: a permeable, b semi-permeable and c impermeable. Three storing conditions were tested: a room temperature and RH under laboratory conditions; b 15ºC and 45% RH; c 20ºC and 55% RH. Water content, germination rate and germination speed index were evaluated at 0, 4, 8 and 12 months of storing. The best germination results were obtained with the moisture range of 6.0≤8.0%, with seeds kept at room temperature; while the seeds stored at 10ºC, regardless the moisture range, did not survive. The stored seeds with 5.9% moisture content and at both 15ºC/45%RH and 20ºC/55% RH conditions, independently of the package type used, showed the best results. Thus, macaw palm seeds can be classified as intermediates seeds.

    2017-09-01

    Full Text Available The world of sports is a reflection of the world of politics. It is becoming increasingly multipolar with the emerging states hosting mega sporting events. Firstly, the article problematizes the concept of multipolarity and, secondly, globalisation by questioning whether the Olympic Games reinforce national identities and promote national interests by using Olympic diplomacy as a soft power tool. In doing so, the article explores the correlation between the changes in international affairs and the hosting of and participation at the Olympic Games by emerging states such as Brazil, China and Russia. The analysis distinguishes globalisation from the role of the nation-state, by highlighting the evident differences between emerging states in terms of hosting the Games, but also takes into consideration geopolitical and geo-economic parameters.

  4. Solid-state supercapacitors with ionic liquid gel polymer electrolyte based on poly (3, 4-ethylenedioxythiophene), carbon nanotubes, and metal oxides nanocomposites for electrical energy storage

    Science.gov (United States)

    Obeidat, Amr M.

    Clean and renewable energy systems have emerged as an important area of research having diverse and significant new applications. These systems utilize different energy storage methods such as the batteries and supercapacitors. Supercapacitors are electrochemical energy storage devices that are designed to bridge the gap between batteries and conventional capacitors. Supercapacitors which store electrical energy by electrical double layer capacitance are based on large surface area structured carbons. The materials systems in which the Faradaic reversible redox reactions store electrical energy are the transition metal oxides and electronically conducting polymers. Among the different types of conducting polymers, poly (3, 4- ethylenedioxythiophene) (PEDOT) is extensively investigated owing to its chemical and mechanical stability. Due to instability of aqueous electrolytes at high voltages and toxicity of organic electrolytes, potential of supercapacitors has not been fully exploited. A novel aspect of this work is in utilizing the ionic liquid gel polymer electrolyte to design solid-state supercapacitors for energy storage. Various electrochemical systems were investigated including graphene, PEDOT, PEDOT-carbon nanotubes, PEDOT-manganese oxide, and PEDOT-iron oxide nanocomposites. The electrochemical performance of solid-state supercapacitor devices was evaluated based on cyclic voltammetry (CV), charge-discharge (CD), prolonged cyclic tests, and electrochemical impedance spectroscopy (EIS) techniques. Raman spectroscopy technique was also utilized to analyze the bonding structure of the electrode materials. The graphene solid-state supercapacitor system displayed areal capacitance density of 141.83 mF cm-2 based on high potential window up to 4V. The PEDOT solid-state supercapacitor system was synthesized in acetonitrile and aqueous mediums achieving areal capacitance density of 219.17 mF cm-2. The hybrid structure of solid-state supercapacitors was also

    This case study evaluated the Mobile Emergency Care Service (SAMU) in Santa Catarina State, Brazil, in 2013/2014. The theoretical log frame and evaluation matrix were validated by expert consensus workshops. Two dimensions were proposed: emergency care management and emergency care, analyzed with 22 indicators. Data collection used interviews, direct observation in the eight regional SAMU dispatches, and a questionnaire sent to the coordinators of the municipal SAMU. The analysis and value judgment according to separate dimensions, sub-dimensions, and indicators allowed identifying strengths and weaknesses amenable to intervention. No regional dispatch performed well in both dimensions; all were classified as "fair" in emergency care and "bad" in emergency management. An important strength was agile communication with callers for help, standardization, and external support for care. The mechanisms for internal and external linkage and communication need to be effectively implemented. The quality of advanced support units requires improvement.

    When quantum fluctuations destroy underlying long-range ordered states, novel quantum states emerge. Spin-liquid (SL) states of frustrated quantum antiferromagnets, in which highly correlated spins fluctuate down to very low temperatures, are prominent examples of such quantum states. SL states often exhibit exotic physical properties, but the precise nature of the elementary excitations behind such phenomena remains entirely elusive. Here, we use thermal Hall measurements that can capture the unexplored property of the elementary excitations in SL states, and report the observation of anomalous excitations that may unveil the unique features of the SL state. Our principal finding is a negative thermal Hall conductivity κxy which the charge-neutral spin excitations in a gapless SL state of the 2D kagomé insulator volborthite Cu3V2O7(OH)2⋅2H2O exhibit, in much the same way in which charged electrons show the conventional electric Hall effect. We find that κxy is absent in the high-temperature paramagnetic state and develops upon entering the SL state in accordance with the growth of the short-range spin correlations, demonstrating that κxy is a key signature of the elementary excitation formed in the SL state. These results suggest the emergence of nontrivial elementary excitations in the gapless SL state which feel the presence of fictitious magnetic flux, whose effective Lorentz force is found to be less than 1/100 of the force experienced by free electrons.

  7. A simple approach to the determination of the charging state of photovoltaic-powered storage batteries

    Science.gov (United States)

    Hamdy, M. A.

    Stand-alone photovoltaic (PV) applications, such as domestic and street lighting systems, usually include a storage battery which is subjected to a daily charge/discharge cycle. During such cycle the battery chargesduring the day and loses a percentage of its charge to the load at night. A knowledge of the battery state-of-charge (SOC) during charging is important since it leads to design information about the desired size of the PV array and battery capacity to satisfy a given load. A simple approach to the theoretical determination of the battery SOC in stand-alone PV systems is presented in this paper. The approach is based on the graphical determination of the system operating points found from the intersection between the I-V curves representing the power source (PV) under varying solar radiation and temperature conditions with the I-V curves representing the load (battery) under varying SOC conditions. The study is restricted to locally manufactured lead/acid batteries used to power TV sets in some of the rural areas of Egypt. It takes into consideration the different factors affecting battery performance. Conclusions are drawn from the analysis that permit a better design of the system for full utilization of the PV output power leading to the appropriate PV size that ensures proper system operation for the designed period.

    Pediatric emergency telemedicine has the potential to improve the quality of pediatric emergency care in underserved areas, reducing socioeconomic disparities in access to care. Yet, telemedicine in the pediatric emergency setting remains underutilized. We aimed to assess the current state of pediatric emergency telemedicine and identify unique success factors and barriers to widespread use. We conducted a telephone survey of current, former, and planned pediatric emergency telemedicine programs in the United States. We surveyed 25 respondents at 20 unique sites, including 12 current, 5 planned, and 3 closed programs. Existing programs were located primarily in academic medical centers and served an average of 12.5 spoke sites (range, 1-30). Respondents identified five major barriers, including difficulties in cross-hospital credentialing, integration into established workflows, usability of technology, lack of physician buy-in, and misaligned incentives between patients and providers. Uneven reimbursement was also cited as a barrier, although this was not seen as major because most programs were able to operate independent of reimbursement, and many were not actively seeking reimbursement even when allowed. Critical success factors included selecting spoke hospitals based on receptivity rather than perceived need and cultivating clinical champions at local sites. Although pediatric emergency telemedicine confronts many of the same challenges of other telemedicine applications, reimbursement is relatively less significant, and workflow disruption are relatively more significant in this setting. Although certain challenges such as credentialing can be addressed with available policy options, others such as the culture of transfer at rural emergency departments require innovative approaches.

    Coronaviruses are known to infect humans and other animals and cause respiratory and gastrointestinal diseases. Here we report the emergence of porcine epidemic diarrhea virus (PEDV) in the United States and determination of its origin, evolution, and genotypes based on temporal and geographical evidence. Histological lesions in small intestine sections of affected pigs and the complete genomic sequences of three emergent strains of PEDV isolated from outbreaks in Minnesota and Iowa were characterized. Genetic and phylogenetic analyses of the three U.S. strains revealed a close relationship with Chinese PEDV strains and their likely Chinese origin. The U.S. PEDV strains underwent evolutionary divergence, which can be classified into two sublineages. The three emergent U.S. strains are most closely related to a strain isolated in 2012 from Anhui Province in China, which might be the result of multiple recombination events between different genetic lineages or sublineages of PEDV. Molecular clock analysis of the divergent time based on the complete genomic sequences is consistent with the actual time difference, approximately 2 to 3 years, of the PED outbreaks between China (December 2010) and the United States (May 2013). The finding that the emergent U.S. PEDV strains share unique genetic features at the 5'-untranslated region with a bat coronavirus provided further support of the evolutionary origin of PEDV from bats and potential cross-species transmission. The data from this study have important implications for understanding the ongoing PEDV outbreaks in the United States and will guide future efforts to develop effective preventive and control measures against PEDV. The sudden emergence of porcine epidemic diarrhea virus (PEDV), a coronavirus, for the first time in the United States causes significant economic and public health concerns. Since its recognition in May 2013, PEDV has rapidly spread across the United States, resulting in high mortality in piglets

    Using forests to mitigate climate change has gained much interest in science and policy discussions. We examine the evidence for carbon benefits, environmental and monetary costs, risks and trade-offs for a variety of activities in three general strategies: (1) land use change to increase forest area (afforestation) and avoid deforestation; (2) carbon management in existing forests; and (3) the use of wood as biomass energy, in place of other building materials, or in wood products for carbon storage. We found that many strategies can increase forest sector carbon mitigation above the current 162-256 Tg C/yr, and that many strategies have co-benefits such as biodiversity, water, and economic opportunities. Each strategy also has trade-offs, risks, and uncertainties including possible leakage, permanence, disturbances, and climate change effects. Because approximately 60% of the carbon lost through deforestation and harvesting from 1700 to 1935 has not yet been recovered and because some strategies store carbon in forest products or use biomass energy, the biological potential for forest sector carbon mitigation is large. Several studies suggest that using these strategies could offset as much as 10-20% of current U.S. fossil fuel emissions. To obtain such large offsets in the United States would require a combination of afforesting up to one-third of cropland or pastureland, using the equivalent of about one-half of the gross annual forest growth for biomass energy, or implementing more intensive management to increase forest growth on one-third of forestland. Such large offsets would require substantial trade-offs, such as lower agricultural production and non-carbon ecosystem services from forests. The effectiveness of activities could be diluted by negative leakage effects and increasing disturbance regimes. Because forest carbon loss contributes to increasing climate risk and because climate change may impede regeneration following disturbance, avoiding

    This publication is the final report of a project to survey the fifty states, the District of Columbia, Puerto Rico, and selected Indian Tribal jurisdictions to ascertain their emergency-preparedness planning and capabilities for responding to transportation incidents involving radioactive materials. The survey was conducted to provide the Nuclear Regulatory Commission and other federal agencies with information concerning the current level of emergency-response preparedness of the states and selected tribes and an assessment of the changes that have occurred since 1980. There have been no major changes in the states' emergency-response planning strategies and field tactics. The changes noted included an increased availability of dedicated emergency-response vehicles, wider availability of specialized radiation-detection instruments, and higher proportions of police and fire personnel with training in the handling of suspected radiation threats. Most Indian tribes have no capability to evaluate suspected radiation threats and have no formal relations with emergency-response personnel in adjacent states. For the nation as a whole, the incidence of suspected radiation threats declined substantially from 1980 to 1988. 58 tabs.

  12. Emergence of low noise frustrated states in E/I balanced neural networks.

    We study emerging phenomena in binary neural networks where, with a probability c synaptic intensities are chosen according with a Hebbian prescription, and with probability (1-c) there is an extra random contribution to synaptic weights. This new term, randomly taken from a Gaussian bimodal distribution, balances the synaptic population in the network so that one has 80%-20% relation in E/I population ratio, mimicking the balance observed in mammals cortex. For some regions of the relevant parameters, our system depicts standard memory (at low temperature) and non-memory attractors (at high temperature). However, as c decreases and the level of the underlying noise also decreases below a certain temperature Tt, a kind of memory-frustrated state, which resembles spin-glass behavior, sharply emerges. Contrary to what occurs in Hopfield-like neural networks, the frustrated state appears here even in the limit of the loading parameter α→0. Moreover, we observed that the frustrated state in fact corresponds to two states of non-vanishing activity uncorrelated with stored memories, associated, respectively, to a high activity or Up state and to a low activity or Down state. Using a linear stability analysis, we found regions in the space of relevant parameters for locally stable steady states and demonstrated that frustrated states coexist with memory attractors below Tt. Then, multistability between memory and frustrated states is present for relatively small c, and metastability of memory attractors can emerge as c decreases even more. We studied our system using standard mean-field techniques and with Monte Carlo simulations, obtaining a perfect agreement between theory and simulations. Our study can be useful to explain the role of synapse heterogeneity on the emergence of stable Up and Down states not associated to memory attractors, and to explore the conditions to induce transitions among them, as in sleep-wake transitions.

    Lu, Xiaonan; Sun, Kai; Guerrero, Josep M.

    2015-01-01

    In this paper, a double-quadrant state-of-charge (SoC) based droop control method for distributed energy storage system (DESS) is proposed to reach the proper power distribution in autonomous DC microgrids. Since DESS is commonly used in DC microgrids, it is necessary to achieve the rational power...... sharing in both charging and discharging process. In order to prolong the lifetime of the energy storage units (ESUs) and avoid the overuse of a certain unit, the SoC of each unit should be balanced and the injected/output power should be gradually equalized. Droop control as a decentralized approach...... is used as the basis of the power sharing method for distributed energy storage units (DESUs). In the charging process, the droop coefficient is set to be proportional to the nth order of SoC, while in the discharging process, the droop coefficient is set to be inversely proportional to the nth order...

    Full Text Available Pupae of Trissolcus basalis (Wollaston and Telenomus podisi Ashmead (Hymenoptera: Scelionidae were stored at 12ºC and 15ºC for 120-210 days, after different periods of parasitism at 18ºC in order to evaluate adult emergence, longevity and ovipositional capacity. There was no emergence of adults at 12ºC. The rate of emergence of parasitoids transferred to 15ºC at the beginning of the pupal stage was 1.5% and 26.3%, for T. basalis and T. podisi respectively, whereas those parasitoids transferred one day before the expected date of emergence at 18ºC showed 86.4% of emergence for T. basalis and 59.9% for T. podisi. Mean adult longevity was also significantly lower when pupae were transferred to 15ºC at the beginning of the pupal stage. Females emerged after storage and maintained for 120 to 210 days at 15ºC parasitized host eggs after transference to 25ºC; however, fecundity of T. podisi was reduced in about 80% after cold storage.Pupas de Trissolcus basalis (Wollaston e Telenomus podisi Ashmead (Hymenoptera: Scelionidae armazenadas a 12ºC e 15ºC por 120 a 210 dias, após diferentes períodos de parasitismo a 18ºC, foram avaliadas quanto à emergência, longevidade e capacidade de parasitismo dos adultos.

    Ambient assisted living can facilitate optimum health and wellness by aiding physical, mental and social well-being. In this paper, patients' psychiatric symptoms are collected through lightweight biosensors and web-based psychiatric screening scales in a smart home environment and then analyzed through machine learning algorithms to provide ambient intelligence in a psychiatric emergency. The psychiatric states are modeled through a Hidden Markov Model (HMM), and the model parameters are estimated using a Viterbi path counting and scalable Stochastic Variational Inference (SVI)-based training algorithm. The most likely psychiatric state sequence of the corresponding observation sequence is determined, and an emergency psychiatric state is predicted through the proposed algorithm. Moreover, to enable personalized psychiatric emergency care, a service a web of objects-based framework is proposed for a smart-home environment. In this framework, the biosensor observations and the psychiatric rating scales are objectified and virtualized in the web space. Then, the web of objects of sensor observations and psychiatric rating scores are used to assess the dweller's mental health status and to predict an emergency psychiatric state. The proposed psychiatric state prediction algorithm reported 83.03 percent prediction accuracy in an empirical performance study.

    Full Text Available In India, the healthcare delivery system starts up from the sub-center at the village level and reaches up to super specialty medical centers providing state of the art emergency medical services (EMS. These highest centers, located in big cities, are considered the last referral points for the patients from nearby cities and states. As the incidents of rail and road accidents have increased in recent years, the role of EMS becomes critical in saving precious lives. But when the facilities and management of these emergency centers succumbs before the patient, then the question arises regarding the adequate availability and quality of EMS. The death of an unknown common man, Rambhor, for want of EMS in three big hospitals in the national capital of India put a big question on the "health" of the emergency health services in India. The emergency services infrastructure seems inadequate and quality and timely provision of EMS to critical patients appears unsatisfactory. There is lack of emergency medicine (EM specialists in India and also the postgraduation courses in EM have not gained foot in our medical education system. Creation of a Centralized Medical Emergency Body, implementation of management techniques, modification of medical curriculum, and fixing accountability are some of the few steps which are required to improve the EMS in India.

    We experimentally demonstrate room-temperature storage of quantum entanglement using two nuclear spins weakly coupled to the electronic spin carried by a single nitrogen-vacancy center in diamond. We realize universal quantum gate control over the three-qubit spin system and produce entangled states in the decoherence-free subspace of the two nuclear spins. By injecting arbitrary collective noise, we demonstrate that the decoherence-free entangled state has coherence time longer than that of other entangled states by an order of magnitude in our experiment.

    One of the limitations to the widespread use of hydrogen as an energy carrier is its storage in a safe and compact form. Herein, recent developments in effective high-capacity hydrogen storage materials are reviewed, with a special emphasis on light compounds, including those based on organic porous structures, boron, nitrogen, and aluminum. These elements and their related compounds hold the promise of high, reversible, and practical hydrogen storage capacity for mobile applications, including vehicles and portable power equipment, but also for the large scale and distributed storage of energy for stationary applications. Current understanding of the fundamental principles that govern the interaction of hydrogen with these light compounds is summarized, as well as basic strategies to meet practical targets of hydrogen uptake and release. The limitation of these strategies and current understanding is also discussed and new directions proposed. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    The recent growth in production and utilization of natural gas offers potential climate benefits, but those benefits depend on lifecycle emissions of methane, the primary component of natural gas and a potent greenhouse gas. This study estimates methane emissions from the transmission and storage (T&S) sector of the United States natural gas industry using new data collected during 2012, including 2,292 onsite measurements, additional emissions data from 677 facilities and activity data from 922 facilities. The largest emission sources were fugitive emissions from certain compressor-related equipment and "super-emitter" facilities. We estimate total methane emissions from the T&S sector at 1,503 [1,220 to 1,950] Gg/yr (95% confidence interval) compared to the 2012 Environmental Protection Agency's Greenhouse Gas Inventory (GHGI) estimate of 2,071 [1,680 to 2,690] Gg/yr. While the overlap in confidence intervals indicates that the difference is not statistically significant, this is the result of several significant, but offsetting, factors. Factors which reduce the study estimate include a lower estimated facility count, a shift away from engines toward lower-emitting turbine and electric compressor drivers, and reductions in the usage of gas-driven pneumatic devices. Factors that increase the study estimate relative to the GHGI include updated emission rates in certain emission categories and explicit treatment of skewed emissions at both component and facility levels. For T&S stations that are required to report to the EPA's Greenhouse Gas Reporting Program (GHGRP), this study estimates total emissions to be 260% [215% to 330%] of the reportable emissions for these stations, primarily due to the inclusion of emission sources that are not reported under the GHGRP rules, updated emission factors, and super-emitter emissions.

    Highlights: •Mechanical alloying with nano-structurizing highly reactive magnesium metal hydrides particles. •Solid reversible hydrogen storage at scale of kg to tons of hydrogen using MgH{sub 2} composite discs. •Natural Expanded Graphite draining heat of reaction during sorption. •Change Phase Material storing reversibly heat of reaction within tank storage as adiabatic system. •Technology fully adapted for renewable energy storage and network energy peak shavings through H{sub 2}. -- Abstract: The renewable resources related, for instance, to solar energies exhibit two main characteristics. They have no practical limits in regards to the efficiency and their various capture methods. However, their intermittence prevents any direct and immediate use of the resulting power. McPhy-Energy proposes solutions based on water electrolysis for hydrogen generation and storage on reversible metal hydrides to efficiently cover various energy generation ranges from MW h to GW h. Large stationary storage units, based on MgH{sub 2}, are presently developed, including both the advanced materials and systems for a total energy storage from ∼70 to more than 90% efficient. Various designs of MgH{sub 2}-based tanks are proposed, allowing the optional storage of the heat of the Mg–MgH{sub 2} reaction in an adjacent phase changing material. The combination of these operations leads to the storage of huge amounts of hydrogen and heat in our so-called adiabatic-tanks. Adapted to intermittent energy production and consumption from renewable sources (wind, sun, tide, etc.), nuclear over-production at night, or others, tanks distribute energy on demand for local applications (on-site domestic needs, refueling stations, etc.) via turbine or fuel cell electricity production.

    Emergency contraception can be used by women after sexual intercourse in an effort to prevent an unintended pregnancy. Roughly one-half of all pregnancies in the United States are unintended (1,2). The FDA first approved emergency contraceptive pills in 1998, but there is evidence of limited use of hormonal contraceptives for emergency contraception since the 1960s (3,4). Now, there are at least four brands of emergency contraceptive pills; most are available over the counter for women aged 17 and over (5). Although insertion of a copper intrauterine device can be used for emergency contraception (1,4), this report focuses only on emergency contraceptive pills. This report describes trends and variation in the use of emergency contraception and reasons for use among sexually experienced women aged 15-44 using the 2006-2010 National Survey of Family Growth. All material appearing in this report is in the public domain and may be reproduced or copied without permission; citation as to source, however, is appreciated.

    During the May 2016 World Health Assembly of 194 member states, the World Health Organization (WHO) announced the process of developing and launching emergency medical teams as a critical component of the global health workforce concept. Over 64 countries have either launched or are in the development stages of vetting accredited teams, both international and national, to provide surge support to national health systems through WHO Regional Organizations and the delivery of emergency clinical care to sudden-onset disasters and outbreak-affected populations. To date, the United States has not yet committed to adopting the emergency medical team concept in funding and registering an international field hospital level team. This article discusses future options available for health-related nongovernmental organizations and the required educational and training requirements for health care provider accreditation.

    Full Text Available Sudan is one of the largest African countries, covering an area of 1.9 million km2—approximately one fifth of the geographic area of the United States. The population is 30 million people, the majority of whom (68% live in rural areas, as compared with the sub-Saharan African average of approximately 62%. Sudan is considered a lower-middle income country—with 47% of the population living below the poverty line and a gross domestic product (GDP of US $62 billion in 2010. In addition to excessive burden of communicable diseases such as malaria, tuberculosis, and schistosomiasis, Sudan is particularly susceptible to both natural and manmade disasters. Drought and flood are quite common due to Sudan’s proximity to and dependency on the Nile, and throughout history Sudan has also been plagued with internal conflicts and outbreaks of violence, which bring about a burden of traumatic disease and demand high quality emergency care. The purpose of this paper is to describe the state of emergency care and Emergency Medicine education, and their context within the Sudanese health care system. As is the case in most African countries, emergency care is delivered by junior staff: new graduates from medical schools and unsupervised medical officers who handle all types of case presentations. In 2001, increased mortality and morbidity among unsorted patients prompted the Ministry of Health to introduce a new triage-based emergency care system. In late 2005, twenty-one Emergency physicians delivered these new Emergency Services. In 2011, following a curriculum workshop in November 2010, the Emergency Medicine residency program was started in Khartoum. Currently there are 27 rotating registrars, the first class of whom is expected to graduate in 2015.

    2014-04-01

    In almost all of the European Union member states, prior consent by a legal representative is used as a substitute for informed patient consent for non-urgent medical research. Deferred (patient and/or proxy) consent is accepted as a substitute in acute emergency research in approximately half of the member states. In 12 European Union member states emergency research is not mentioned in national law. Medical research in the European Union is covered by the Clinical Trial Directive 2001/20/EC. A proposal for a regulation by the European Commission is currently being examined by the European Parliament and the Council and will replace Directive 2001/20/EC. Deferred patient and/or proxy consent is allowed in the proposed regulation, but does not fit completely in the practice of emergency research. For example, deferred consent is only possible when legal representatives are not available. This criterion will delay inclusion of patients in acute life-threatening conditions in short time frames. As the regulation shall be binding in its entirety in all member states, emergency research in acute situations is still not possible as it should be.

    Full Text Available Aim: Sudden neurologic states of various aetiology are the major reason for medical teams to be dispatched and often result in hospitalization of the patient. The purpose of this work was the analysis of the aforementioned neurologic states and pinpointing the type of patients the Emergency Medical Service teams have encountered in Rybnik with respect to the said states. Method: Analysed material consisted of Medical Emergency Action cards that were used by Emergency Medical Service Independent Public Healthcare District Hospital No. 3 in Rybnik in the year 2013. Five hundred and twenty-three cases were selected as consistent with sudden neurologic states. Result: A higher incidence of studied diseases was noted among male patients, whereas in females presenting with these states, the age was higher, with the exception of syncope. The analysis revealed the presence of characteristic symptoms in relevant emergency conditions. During the evaluation of psychomotor abilities, a prevalence of patients whose state qualified as normal, and in the case of stroke as “slowed down” was recorded. Brain damage in all states except for stroke was classified as mild. The study noted high blood glucose level disparities between measurements. Conclusion: Strokes occurred most often in patients over 60 years old. The observed signs were consistent with those described in the literature. Blood glucose test results in some patients allowed suspicion of diabetes, or ruled out hypoglycaemia. The majority of studied patients revealed mild brain injury. Alcohol had a significant effect on the incidence of head injuries and seizures.

    Over the past 15 years, violent threats and acts against hospital patients, staff, and providers have increased and escalated. The leading area for violence is the emergency department (ED) given its 24/7 operations, role in patient care, admissions gateway, and center for influxes during acute surge events. This investigation had three objectives: to assess the current security of Washington State EDs; to estimate the prevalence of and response to threats and violence in Washington State EDs; and to appraise the Washington State ED security capability to respond to acute influxes of patients, bystanders, and media during acute surge events. A voluntary, blinded, 28-question Web-based survey developed by emergency physicians was electronically delivered to all 87 Washington State ED directors in January 2013. We evaluated responses by descriptive statistical analyses. Analyses occurred after 90% (78/87) of ED directors responded. Annual censuses of the EDs ranged from surge event, 35% believed the initial additional security response would not be adequate, with 26% reporting no additional security would be available within 15 minutes. Our study reveals the variability of ED security staffing and a heterogeneity of capabilities throughout Washington State. These deficiencies and vulnerabilities highlight the need for other EDs and regional emergency preparedness planners to conduct their own readiness assessments.

    Although they are infrequent, acute chemical incidents (i.e., uncontrolled or illegal release or threatened release of hazardous substances lasting inherently safer design, developing geographic mapping of chemically vulnerable areas, and adopting the principles of green chemistry (design of chemical products and processes that reduce or eliminate the generation of hazardous substances). Because the more populous states such as New York and Texas had the most incidents, areas with high population density should be carefully assessed for preparedness and prevention measures. NTSIP develops estimated incident numbers for states that do not collect data to help with state and national planning. NTSIP also collects more detailed data on chemical incidents with mass casualties. HSEES and NTSIP data can be used by public and environmental health and safety practitioners, worker representatives, emergency planners, preparedness coordinators, industries, emergency responders, and others to prepare for and prevent chemical incidents and injuries.

    The relation between large-scale brain structure and function is an outstanding open problem in neuroscience. We approach this problem by studying the dynamical regime under which realistic spatiotemporal patterns of brain activity emerge from the empirically derived network of human brain neuroanatomical connections. The results show that critical dynamics unfolding on the structural connectivity of the human brain allow the recovery of many key experimental findings obtained from functional magnetic resonance imaging, such as divergence of the correlation length, the anomalous scaling of correlation fluctuations, and the emergence of large-scale resting state networks.

    Due to its high specific energy content, liquid hydrogen (LH2) is emerging as an alternative fuel for future aircraft. As a result, there is a need for hydrogen tank storage systems, for these aircraft applications, that are expected to provide sufficient capacity for flight durations ranging from a few minutes to several days. It is understood that the development of a large, lightweight, reusable cryogenic liquid storage tank is crucial to meet the goals of and supply power to hydrogen-fueled aircraft, especially for long flight durations. This report provides an annotated review (including the results of an extensive literature review) of the current state of the art of cryogenic tank materials, structural designs, and insulation systems along with the identification of key challenges with the intent of developing a lightweight and long-term storage system for LH2. The broad classes of insulation systems reviewed include foams (including advanced aerogels) and multilayer insulation (MLI) systems with vacuum. The MLI systems show promise for long-term applications. Structural configurations evaluated include single- and double-wall constructions, including sandwich construction. Potential wall material candidates are monolithic metals as well as polymer matrix composites and discontinuously reinforced metal matrix composites. For short-duration flight applications, simple tank designs may suffice. Alternatively, for longer duration flight applications, a double-wall construction with a vacuum-based insulation system appears to be the most optimum design. The current trends in liner material development are reviewed in the case that a liner is required to minimize or eliminate the loss of hydrogen fuel through permeation.

    Limited knowledge and practice of contraception is a global public health problem. Unintended pregnancies are the primary cause of induced abortion. When safe abortions are not available, as in Nigeria with restricted abortion laws, abortion can contribute significantly to maternal mortality and morbidity. Adequate information on the awareness and the use of emergency contraception is necessary for planning interventions in groups vulnerable to unwanted pregnancy. The aim of the following study is to access the awareness, perception and practice of emergency contraception among female undergraduates in Imo State University, South Eastern Nigeria. A questionnaire based cross-sectional survey using female undergraduates selected randomly from Imo State University, Owerri. A total of 700 students participated in the study. Awareness of emergency contraception was very high (85.1%) (596/700). The awareness was significantly higher amongst students in health related faculties than in the non-health related faculties (P = 0.01). The main sources of information were through friends (43.1%) (317/700) and lectures (22.1%) (192/700). High dose progestogen (postinor-2) was the most commonly known type of emergency contraception (70.8%) (422/596). Only 58.1% (346/596) of those who were aware of emergency contraception approved of their use. The major reasons given by the 41.9% (250/596) who disapproved of their use were religious reasons (50.4%) (126/250) and that they were harmful to health (49.2%) (123/250). Two-third (67%) (46 9/700) of the students were sexually active and only 39.9% (187/469) of them used emergency contraception. High dose progestogen (postinor-2) was again the most commonly used method (70.8%) (422/596). The most common situation in which emergency contraception was used was following unprotected sexual intercourse (45.5%) (85/144). Only 34.6% (206/596) of those who were aware of emergency contraception identified correctly the appropriate time interval

  16. State of emergency: behavior of gerbils is affected by the hunger state of their predators.

    2010-02-01

    Predator-prey interactions are usually composed of behaviorally sophisticated games in which the values of the strategies of foraging prey individuals may depend on those of their predators, and vice versa. Therefore, any change in the behavior of the predator should result in changes to the behavior of the prey. However, this key prediction has rarely been tested. To examine the effects of the predator state on prey behavior, we manipulated the state of captive Barn Owls, Tyto alba, and released them into an enclosure containing Allenby's gerbils, Gerbillus andersoni allenbyi, a common prey of the owls. The owls were significantly more active when hungry. In response, the gerbils altered their behavior according to the state of the owl. When the owl was hungry, the gerbils visited fewer food patches, foraged in fewer patches, and harvested less food from each patch. Moreover, the gerbils kept their foraging bouts closer to their burrow, which reduced the overlap among foraging ranges of individual gerbils. Thus, changes in the state of the predator affect the foraging behavior of its prey and can also mediate competition among prey individuals.

    Renewable energy storage is a key issue in our modern electricity-powered society. Lead acid batteries (LABs) are operated at partial state of charge in renewable energy storage system, which causes the sulfation and capacity fading of Pb electrode. Lead-carbon composite electrode is a good solution to the sulfation problem of LAB. In this paper, a rice-husk-derived hierarchically porous carbon with micrometer-sized large pores (denoted as RHC) has been used as the component of lead-carbon composite electrode. Scanning electron microscopy was used to characterize the morphology of lead-carbon composite electrode. Electrochemical impedance spectroscopy was used to determine the charge transfer capability of lead-carbon composite electrode. Both full charge-discharge method and charge-discharge method operating at harsh partial state of charge condition have been used to prove the superior energy storage capability of lead-carbon composite electrode. Experiment results prove that the micrometer-sized pores of RHC are beneficial to the construction and stability of lead-carbon composite electrode. Microporous carbon material with high surface area is not suitable for the construction of lead-carbon electrode due to the ruin of lead-carbon structure caused by severe electrochemical hydrogen evolution.

    2014-01-01

    A relational database management system (RDBMS) is designed based on NAND flash solid-state drive (SSD) for storage. By vertically integrating the storage engine (SE) and the flash translation layer (FTL), system performance is maximized and the internal SSD overhead is minimized. The proposed RDBMS SE utilizes physical information about the NAND flash memory which is supplied from the FTL. The query operation is also optimized for SSD. By these treatments, page-copy-less garbage collection is achieved and data fragmentation in the NAND flash memory is suppressed. As a result, RDBMS performance increases by 3.8 times, power consumption of SSD decreases by 46% and SSD life time is increased by 61%. The effectiveness of the proposed scheme increases with larger erase block sizes, which matches the future scaling trend of three-dimensional (3D-) NAND flash memories. The preferable row data size of the proposed scheme is below 500 byte for 16 kbyte page size.

  4. Cellular Nonlinear Networks for the emergence of perceptual states: application to robot navigation control.

    Arena, Paolo; De Fiore, Sebastiano; Patané, Luca

    2009-01-01

    In this paper a new general purpose perceptual control architecture, based on nonlinear neural lattices, is presented and applied to solve robot navigation tasks. Insects show the ability to react to certain stimuli with simple reflexes, using direct sensory-motor pathways, which can be considered as basic behaviors, inherited and pre-wired. Relevant brain centres, known as Mushroom Bodies (MB) and Central Complex (CX) were recently identified in insects: though their functional details are not yet fully understood, it is known that they provide secondary pathways allowing the emergence of cognitive behaviors. These are gained through the coordination of the basic abilities to satisfy the insect's needs. Taking inspiration from this evidence, our architecture modulates, through a reinforcement learning, a set of competitive and concurrent basic behaviors in order to accomplish the task assigned through a reward function. The core of the architecture is constituted by the so-called Representation layer, used to create a concise picture of the current environment situation, fusing together different stimuli for the emergence of perceptual states. These perceptual states are steady state solutions of lattices of Reaction-Diffusion Cellular Nonlinear Networks (RD-CNN), designed to show Turing patterns. The exploitation of the dynamics of the multiple equilibria of the network is emphasized through the adaptive shaping of the basins of attraction for each emerged pattern. New experimental campaigns on standard robotic platforms are reported to demonstrate the potentiality and the effectiveness of the approach.

    Full Text Available Biological samples collected in biobanks are a resource with significant research potential. The Italian Joint Group cNB - cNBBSV (National committee of Bioethics - National committee for Biosecurity, Biotechnologies and Life Sciences published a document reporting recommendations on storage and use of dried blood spot (DBS and on the development of a National Network of Regional Newborn Screening Repositories for collection of residual DBS. Several ethical questions (about consent, possible use of genetic information, unanticipated possible usages for research purposes rise from residual newborn screening specimens collections. Moreover, legal and ethical controversies are accentuated by the conflicts between the interests of sample donors, biobank holders, researchers and the public. To overcome these difficulties the identification of a few criteria for storage and research usage of DBS is crucial.

  6. Thiol-Disulfide Exchange in Peptides Derived from Human Growth Hormone during Lyophilization and Storage in the Solid State

    Lyophilization (freeze-drying) is frequently used to stabilize protein therapeutics. However, covalent modifications such as thiol-disulfide exchange and disulfide scrambling can occur even in the solid state. The effects of lyophilization and storage of lyophilized powders on the mechanism and kinetics of thioldisulfide exchange have not been elucidated and are explored here. Reaction kinetics were monitored in peptides corresponding to tryptic fragments of human growth hormone (T20 + T20-T21 or T20 + cT20-T21) during different stages of lyophilization and during storage of the lyophilized powders at 22 °C and ambient RH. The concentrations of reactants and products were determined using RP-HPLC and product identity confirmed using LC-MS. Loss of native disulfide was observed for the reaction of T20 with both linear (T20-T21) and cyclic (cT20-T21) peptides during the primary drying step, however, the native disulfides were regenerated during secondary drying with no further change till the end of lyophilization. Deviations from Arrhenius parameters predicted from solution studies and the absence of buffer effects during lyophilization suggest that factors such as temperature, initial peptide concentration, buffer type and concentration do not influence thiol-disulfide exchange during lyophilization. Results from a ‘cold finger’ method used to study peptide adsorption to ice indicate that there is no preferential adsorption to the ice surface and that its presence may not influence disulfide reactivity during primary drying. Overall, reaction rates and product distribution differ for the reaction of T20 with T20-T21 or cT20-T21 in the solid state and aqueous solution, while the mechanism of thiol-disulfide remains unchanged. Increased reactivity of the cyclic peptide in the solid state suggests that peptide cyclization does not offer protection against lyophilization and that damage induced by a process stress further affects storage stability at 22 °C and

    Human insulin is a pivotal protein hormone controlling metabolism, growth, and aging and whose malfunctioning underlies diabetes, some cancers, and neurodegeneration. Despite its central position in human physiology, the in vivo oligomeric state and conformation of insulin in its storage granules in the pancreas are not known. In contrast, many in vitro structures of hexamers of this hormone are available and fall into three conformational states: T6, T3Rf3, and R6 As there is strong evidence for accumulation of neurotransmitters, such as serotonin and dopamine, in insulin storage granules in pancreatic β-cells, we probed by molecular dynamics (MD) and protein crystallography (PC) if these endogenous ligands affect and stabilize insulin oligomers. Parallel studies independently converged on the observation that serotonin binds well within the insulin hexamer (site I), stabilizing it in the T3R3 conformation. Both methods indicated serotonin binding on the hexamer surface (site III) as well. MD, but not PC, indicated that dopamine was also a good site III ligand. Some of the PC studies also included arginine, which may be abundant in insulin granules upon processing of pro-insulin, and stable T3R3 hexamers loaded with both serotonin and arginine were obtained. The MD and PC results were supported further by in solution spectroscopic studies with R-state-specific chromophore. Our results indicate that the T3R3 oligomer is a plausible insulin pancreatic storage form, resulting from its complex interplay with neurotransmitters, and pro-insulin processing products. These findings may have implications for clinical insulin formulations. © 2017 by The American Society for Biochemistry and Molecular Biology, Inc.

    Full Text Available After the green revolution, we are now ushering in the evergreen revolution in the country; food processing is an evergreen activity. It is the key to the agricultural sector. In this paper an attempt has been made to study the workings of food processing units with special references to Red Chilli Cold Storage units in the Byadgi district of Karnataka State. Byadgi has been famous for Red Chilli since the days it’s of antiquity. The vast and extensive market yard in Byadagi taluk is famous as the second largest Red Chilli dealing market in the country. However, the most common and recurring problem faced by the farmer is inability to store enough red chilli from one harvest to another. Red chilli that was locally abundant for only a short period of time had to be stored against times of scarcity. In recent years, due to Oleoresin, demand for Red Chilli has grow from other countries like Sri Lanka, Bangladesh, America, Europe, Nepal, Indonesia, Mexico etc. The study reveals that all the cold storage units of the study area have been using vapour compression refrigeration system or method. All entrepreneurs have satisfied with their turnover and profit and they are in a good economic position. Even though the average turnover and profits are increased, few units have shown negligible amount of decrease in turnover and profit. This is due to the competition from increasing number of cold storages and early established units. The cold storages of the study area have been storing Red chilli, Chilli seeds, Chilli powder, Tamarind, Jeera, Dania, Turmeric, Sunflower, Zinger, Channa, Flower seeds etc,. But the 80 per cent of the each cold storage is filled by the red chilli this is due to the existence of vast and extensivered chilli market yard in the Byadgi. There is no business without problems. In the same way the entrepreneurs who are chosen for the study are facing a few problems in their business like skilled labour, technical and management

    Full Text Available To determine the risk for Chagas disease (American trypanosomiasis in the United States, the characteristics that make the triatomine vector effective and the areas most at risk for transmission were delineated. In addition, the status of Chagas disease awareness among physicians in areas with a potential risk for the disease was determined. A geographical information system (GIS was used to analyze three triatomine species within the United States known to harbor Trypanosoma cruzi and that exhibit qualities of domesticity. An analysis of the minimum temperature threshold for increased triatomine activity delineates the current population at increased risk, and by incorporating temperature predictions for 2030, the population at risk under a future climate scenario was also delineated. Considering both environmental and social factors, a vignette-based physician survey, based on the results of the GIS analysis, was used to gauge the level of awareness of Chagas disease within the delineated higher risk range. The current area at increased risk for Chagas disease includes much of the southern United States, and the higher risk range is expected to expand into the central United States based upon the 1°C (1.8°F increase in temperature predicted by the Intergovernmental Panel on Climate Change (IPCC by the year 2030. Survey results indicate a limited consideration of Chagas disease during differential diagnosis, illustrating that the low number of Chagas disease cases discovered in the United States may be attributable to a lack of disease awareness as opposed to a lack of disease threat. This study combines GIS and survey analyses to evaluate the role that temperature variability and disease awareness among physicians play in the potential emergence of Chagas disease in the United States. This approach indicates that there is a potential for Chagas disease to emerge in the United States.

    Sikkim, India’s model development state, is rapidly urbanising. Producing the model development state requires wide-ranging control over space through laws, regulations, and coercion. Controls over space—and its limits—are most pronounced in the state’s emerging urban areas. Jorethang, a densely...... populated town on Sikkim’s southern border, is the underbelly of the model development state. Jorethang functions as a zone of transgression that blurs urban and rural, migrant and citizen/subject, and licit and illicit. Using a walking ethnography of Jorethang town and surrounds we make three arguments...... to work on infrastructure projects, private construction, services, and illicit trade. Third, Jorethang offers a glimpse of Sikkim’s bifurcated urban future. While model modernity is manifest in showpiece urban areas such as Namchi and Gangtok, Jorethang has become a zone to supply, service, and profit...

    2015-03-01

    Full Text Available This paper historicizes when wearing vintage clothing first became fashionable in the United States. I trace when the trend emerges in the U.S. and explore various ways the press framed secondhand/vintage clothes and anachronistic dressing. I contend that the emergence of vintage occurs as a form of alternative consumption alongside changes that occurred in the U.S. garment industry such as outsourcing and product licensing. These changes led many consumers to seek more authentic consumption experiences. Consumers with cultural capital found in vintage an alternative market for sourcing fashionable street style. Consumers attribute characteristics to vintage clothing that are typically part of authenticity discourse such as it being of exceptional quality, original, handcrafted, made from natural fibers, and providing continuity with the past. The authenticity of vintage is symbolically deployed in opposition to contemporary mass-produced clothing and standardized retail shopping experiences.

  14. Strength analysis and optimization of welding robot mechanism in emergency stop state

    Zdeněk Poruba

    2016-03-01

    Full Text Available The contribution deals with the strength analysis and optimization of the welding robot mechanism in emergency stop state. The common operational positioning of the welding robot is characterized by smooth course of speeds in the time. The resulting load does not differ significantly from the static loading. However the safety requirements given by the norm require the ability of emergency stop function. Since the course of speed in time is rather steep the higher values of acceleration and thus higher excitation force is expected. The dynamical simulation performed describes the response of the robot mechanism in the form of stress course in time, quantifies the peak values of the stress caused by the dynamical component of loading and highlights the potential risks associated with this phenomenon.

    Full Text Available Introduction: Over the past 15 years, violent threats and acts against hospital patients, staff, and providers have increased and escalated. The leading area for violence is the emergency department (ED given its 24/7 operations, role in patient care, admissions gateway, and center for influxes during acute surge events. This investigation had three objectives: to assess the current security of Washington State EDs; to estimate the prevalence of and response to threats and violence in Washington State EDs; and to appraise the Washington State ED security capability to respond to acute influxes of patients, bystanders, and media during acute surge events. Methods: A voluntary, blinded, 28-question Web-based survey developed by emergency physicians was electronically delivered to all 87 Washington State ED directors in January 2013. We evaluated responses by descriptive statistical analyses. Results: Analyses occurred after 90% (78/87 of ED directors responded. Annual censuses of the EDs ranged from < 20,000 to 100,000 patients and represented the entire spectrum of practice environments, including critical access hospitals and a regional quaternary referral medical center. Thirty-four of 75 (45% reported the current level of security was inadequate, based on the general consensus of their ED staff. Nearly two-thirds (63% of EDs had 24-hour security personnel coverage, while 28% reported no assigned security personnel.

    Micro/nano-architectured transition-metal@C hybrids possess unique structural and compositional features toward lithium storage, and are thus expected to manifest ideal anodic performances in advanced lithium-ion batteries (LIBs). Herein, we propose a facile and scalable solid-state coordination and subsequent pyrolysis route for the formation of a novel type of micro/nano-architectured transition-metal@C hybrid (i.e., Ni@C nanosheet-assembled hierarchical network, Ni@C network). Moreover, this coordination-pyrolysis route has also been applied for the construction of bare carbon network using zinc salts instead of nickel salts as precursors. When applied as potential anodic materials in LIBs, the Ni@C network exhibits Ni-content-dependent electrochemical performances, and the partially-etched Ni@C network manifests markedly enhanced Li-storage performances in terms of specific capacities, cycle life, and rate capability than the pristine Ni@C network and carbon network. The proposed solid-state coordination and pyrolysis strategy would open up new opportunities for constructing micro/nano-architectured transition-metal@C hybrids as advanced anode materials for LIBs.

    Full Text Available This paper analysed the factors responsible for the re-emergence of cholera and predicted the future occurrence of Cholera in Lagos State, Nigeria using factor analysis, multiple linear regression analysis and a cellular automata model for the prediction. The study revealed six Local Government Areas (LGAs under very high threat, nine under low threat, and Surulere and some parts of Amuwo Odofin under medium threat in the near future. These areas have an average population of 200,000 people each with the total tending towards millions of people, all under threat of cholera occurring and re-emerging in their communities. The factors relating to the re-emergence of the disease were discovered to be environmental (rainfall, R2=0.017, P0.05; socio-economic (household size R2=0.816, P>0.05; income, R2=0.880, P>0.05; and education, R2=0.827, P>0.05. The Cellular Automata Markov Prediction model showed that by 2016, Lagos State will experience 79 cholera cases which will increase to 143 in 2020. This prediction model revealed that Ikorodu will record 40 cases, Apapa 12, Ojo 5, Mushin 3, while Amuwo-Odofin, Badagry and Ajeromi-Ifelodun LGAs will each record 2 cases between 2011 and 2016. The study concludes that there is a cholera threat in Lagos State and the factors of vulnerability that predispose people to the disease must be tackled over time and space for effective prevention, control and management of the disease.

    The law in Japan requires the declaration of a state of emergency and implementation of countermeasures for an epidemic of a new infectious disease. However, because a state of emergency has never been declared in Japan, its effects remain unknown. The required countermeasures are similar to those implemented in the foot-and-mouth disease epidemic in Miyazaki in 2010. This study aimed to quantitatively estimate the effect of the declaration in 2010 and investigate the nature of the epidemic based on the day on which the declaration took effect. Only publicly available data were used. Data for farms in the most affected town were analyzed. A modified susceptible-infected-recovered model was used to estimate the effect and for the simulation. Another model was used to estimate the effective reproduction number. After the declaration, the intra-bovine transmission rate decreased by 18.1 %, and there were few days when the effective reproduction number was >1.0. A few weeks delay in the declaration significantly increased the possibility of epidemic, number of farms at peak, and final infection scale. Based on the substantial decrease in the transmission rate after the declaration of a state of emergency in 2010, a future declaration will have a similar effect for a new infectious disease even though a direct extrapolation is not valid. Although a declaration should be carefully considered owing to the potential socioeconomic effects, it is essential to prepare for the implementation given that a delay of only a few weeks should be acceptable.

  20. A local control strategy for power systems in transient emergency state; Part 1: functional design

    Aliyu, U.; El-Abiad, A.H.

    1982-11-01

    This paper is concerned with the investigation of a systematic corrective control approach for the transient emergency state problem of the power system. The proposed new control framework involves distributing the task of system transient stability margin improvement among several local facilities dedicated to the various subsystems comprising the power system. The functional design of the various local controllers to undertake local information processing and provide appropriate closed-loop stabilizing control action during severe transient disturbance is presented. An illustrative example is included to demonstrate the effectiveness of the proposed local control framework.

    Resilience has been recognized as an important phenomenon for understanding how individuals overcome difficult situations. However, it is not only individuals who face difficulties; it is not uncommon for teams to experience adversity. When they do, they must be able to overcome these challenges without performance decrements.This manuscript represents a theoretical model that might be helpful in conceptualizing this important construct. Specifically, it describes team resilience as a second-order emergent state. We also include research propositions that follow from the model. PMID:28861013

  2. Do multiple hydrological steady states exist and emerge under stochastic daily forcing?

    Recent work has shown that including positive feedbacks in hydrological models can result in complex behavior with multiple steady states (henceforth attractors) and a finite resilience from a single parameter set. More generally, this is typical of systems with positive feedbacks. However, a limitation of past studies is that multiple attractors were identified using mean annual or monthly forcing. Considering that most hydrological fluxes do not operate at such large time scales, it remains an open question whether multiple hydrological attractors can exist when a catchment is subject to stochastic daily forcing. To explore this question, this paper summarizes three recently submitted WRR papers (Peterson et al. 2012a, 2012b, 2012c) to ask if multiple hydrological attractors can emerge under stochastic daily forcing; and if they emerge, can daily forcing cause a catchment to switch between them. Using a hill-slope Boussinesq-vadose zone semi-distributed model, the attractors were quantified using a new limit-cycle continuation technique (LCC) that up-scaled climate forcing from daily to monthly (model and limit-cycle code is freely available). Multiple attractors were found to exist; but over a narrower range of parameter values compared with that using monthly mean forcing. This suggested that multiple attractors may exist in fewer catchments. To explore if stochastic daily forcing can switch a catchment to both attractors, time-integration simulations under daily stochastic forcing where conducted at a range of saturated lateral conductivity values. Somewhat surprisingly, the emergence (under stochastic forcing) of attractors differed significantly from the attractors that existed (from LCC). Specifically, attractors were found to exist but never emerge; both attractors may exist and both may emerge; and only one attractor may exist and a second temporary attractor may emerge only during certain periods of stochastic forcing. The latter indicates that more

    Full Text Available Distributed energy storage (DES plays an important role in microgrid operation and control, as it can potentially improve local reliability and resilience, reduce operation cost, and mitigate challenges caused by high penetration renewable generation. However, to ensure an acceptable economic and technical performance, DES must be optimally sized and placed. This paper reviews the existing DES sizing methods for microgrid applications and presents a generic sizing method that enables microgrid planners to efficiently determine the optimal DES size, technology, and location. The proposed method takes into consideration the impact of DES operation on its lifetime to enhance the obtained results accuracy and practicality. The presented model can be used for both grid-tied (considering both grid-connected and islanded modes and isolated microgrids.

    2010-07-21

    A system composed of identical spins and described by a quantum mechanical pure state is analyzed within the statistical framework presented in Part I of this work. We explicitly derive the typical values of the entropy, of the energy, and of the equilibrium reduced density matrix of a subsystem for the two different statistics introduced in Part I. In order to analyze their consistency with thermodynamics, these quantities of interest are evaluated in the limit of large number of components of the isolated system. The main results can be summarized as follows: typical values of the entropy and of the equilibrium reduced density matrix as functions of the internal energy in the fixed expectation energy ensemble do not satisfy the requirement of thermodynamics. On the contrary, the thermodynamical description is recovered from the random pure state ensemble (RPSE), provided that one considers systems large enough. The thermodynamic limit of the considered properties for the spin system reveals a number of important features. First canonical statistics (and thus, canonical typicality as long as the fluctuations around the average value are small) emerges without the need of assuming the microcanonical space for the global pure state. Moreover, we rigorously prove (i) the equivalence of the "global temperature," derived from the entropy equation of state, with the "local temperature" determining the canonical state of the subsystems; and (ii) the equivalence between the RPSE typical entropy and the canonical entropy for the overall system.

    Noroviruses are the leading cause of gastroenteritis in the United States, but timely measures of disease are lacking. BioSense, a national-level electronic surveillance system, assigns data on chief complaints (patient symptoms) collected during emergency department (ED) visits to 78 subsyndromes in near real-time. In a series of linear regression models, BioSense visits mapped by chief complaints of diarrhea and nausea/vomiting subsyndromes as a monthly proportion of all visits correlated strongly with reported norovirus outbreaks from 6 states during 2007–2010. Higher correlations were seen for diarrhea (R = 0.828–0.926) than for nausea/vomiting (R = 0.729–0.866) across multiple age groups. Diarrhea ED visit proportions exhibited winter seasonality attributable to norovirus; rotavirus contributed substantially for children norovirus season within 4 weeks of observed dates and could be reliable, timely indicators of norovirus activity.

    In this study, the aim was to establish if loss of DNA integrity is a cause of loss of culturability for probiotic bacteria during storage in dry state. The number of colony forming units (CFU), number of metabolically active cells, and DNA integrity during dry storage of probiotic strains, B. animalis subsp. lactis BB-12 and L. acidophilus LA-5, were investigated. The probiotic strains were freeze-dried and stored at 20°C, with and without oxygen present, and at water activity levels 0.22 or 0.32. Dry storage resulted in a decrease in CFU during the entire storage period. The number of metabolically active cells was unchanged during storage of B. animalis subsp. lactis BB-12, but did decrease during the first week of storage of L. acidophilus LA-5. Loss of DNA integrity was evident for both strains during storage and correlated well with the loss of CFU. Both loss of CFU and loss of DNA integrity were significantly greater for both strains when oxygen was present and when aw was increased. Statistical analysis indicates a possible causal relationship between DNA degradation and loss of culturability and this idea is consistent with the function of DNA at cell division. The study contributes with new knowledge of the cause for loss of CFU during dry storage of probiotic bacteria, which possibly can aid in the improvement of preservation techniques. © 2017 American Institute of Chemical Engineers Biotechnol.

    Full Text Available OBJECTIVE: The objectives of the current study are to provide nationally representative estimates of hospital based emergency department visits (ED attributed to self inflicted injuries and attempted suicides among children in United States; and to identify potential methods of such intentional self inflicted injuries and attempted suicides. METHODS: The Nationwide Emergency Department Sample (year 2007 was used. All ED visits occurring among children (aged ≤18 years with an External Cause of Injury for any of self inflicted injuries were selected. Outcomes examined include hospital ED charges and hospitalization charges. All estimates were projected to national levels. RESULTS: 77,420 visits to hospital based emergency departments were attributed to self inflicted injuries among children (26,045 males and 51,370 females. The average age of the ED visits was 15.7 years. 134 patients died in ED's (106 males and 28 females and 93 died in hospitals following in-patient admission (75 males and 18 females. A greater proportion of male ED visits were discharged routinely as opposed to female ED visits (51.1% versus 44%. A greater proportion of male ED visits also died in the emergency departments compared to female visits (0.4% versus 0.05%. 17,965 ED visits necessitated admission into same hospital. The mean charge for each ED visit was $1,874. Self inflicted injuries by poisoning were the most frequently reported sources accounting for close to 70% of all ED visits. CONCLUSIONS: Females comprise a greater proportion of ED visits attributed to self inflicted injuries. 227 children died either in the ED's or in hospitals. The current study results highlight the burden associated with such injuries among children.

  12. Model describing the effect of employment of the United States military in a complex emergency.

    2005-01-01

    The end of the Cold War vastly altered the worldwide political landscape. With the loss of a main competitor, the United States (US) military has had to adapt its strategic, operational, and tactical doctrines to an ever-increasing variety of non-traditional missions, including humanitarian operations. Complex emergencies (CEs) are defined in this paper from a political and military perspective, various factors that contribute to their development are described, and issues resulting from the employment of US military forces are discussed. A model was developed to illustrate the course of a humanitarian emergency and the potential impact of a military response. The US intervention in Haiti, Northern Iraq, Kosovo, Somalia, Bosnia, and Rwanda serve as examples. A CE develops when there is civil conflict, loss of national governmental authority, a mass population movement, and massive economic failure, each leading to a general decline in food security. The military can alleviate a CE in four ways: (1) provide security for relief efforts; (2) enforce negotiated settlements; (3) provide security for non-combatants; and/or (4) employ logistical capabilities. The model incorporates Norton and Miskel's taxonomy of identifying failing states and helps illustrate the factors that lead to a CE. The model can be used to determine if and when military intervention will have the greatest impact. The model demonstrates that early military intervention and mission assignment within the core competencies of the forces can reverse the course of a CE. Further study will be needed to verify the model.

  13. All-MXene (2D titanium carbide) solid-state microsupercapacitors for on-chip energy storage

    2016-08-01

    On-chip energy storage is a rapidly evolving research topic, opening doors for integration of batteries and supercapacitors at microscales on rigid and flexible platforms. Recently, a new class of two-dimensional (2D) transition metal carbides and nitrides (so-called MXenes) has shown great promise in electrochemical energy storage applications. Here, we report the fabrication of all-MXene (Ti3C2Tx) solid-state interdigital microsupercapacitors by employing a solution spray-coating, followed by a photoresist-free direct laser cutting method. Our prototype devices consisted of two layers of Ti3C2Tx with two different flake sizes. The bottom layer was stacked large-size MXene flakes (typical lateral dimensions of 3-6 μm) serving mainly as current collectors. The top layer was made of small-size MXene flakes (~1 μm) with a large number of defects and edges as the electroactive layer responsible for energy storage. Compared to Ti3C2Tx micro-supercapacitors with platinum current collectors, the all-MXene devices exhibited much lower contact resistance, higher capacitances and better rate-capabilities. The areal and volumetric capacitances of ~27 mF cm-2 and ~337 F cm-3, respectively, at a scan rate of 20 mV s-1 were achieved. The devices also demonstrated their excellent cyclic stability, with 100% capacitance retention after 10,000 cycles at a scan rate of 50 mV s-1. This study opens up a plethora of possible designs for high-performance on-chip devices employing different chemistries, flake sizes and morphologies of MXenes and their heterostructures.

    Herein, the novel concept of a solid-state electrode materials with ionic-liquid (IL) properties is presented. These composite materials are a mixture of electroactive matter, an electronic conductor, a solid-state ionic conductor and a polymeric binder. The approach of a solid-state ionic conductor combines the high safety of an IL with the nanoconfinement of such a liquid in a mesoporous silica framework, an ionogel, thus leading to a solid with liquid-like ionic properties. The same ionic conductor is also used as a solid-state separator to evaluate the properties of our solid-state electrode materials in all-solid-state batteries. Such a concept of a solid-state electrode material contributes to addressing the challenge of energy storage, which is one of the major challenges of the 21{sup st} century. The ionogel, along with its processability, allows a single-step preparation of the assembly of the solid-state electrode and solid-electrolyte separator and can be applied without specific adaptation to present, thick electrodes prepared by the widespread tape-casting technique. The filling of the electrode porosity by an ionogel is shown by elemental mapping using scanning electron microscopy, and is subsequently confirmed by electrochemical measurements. The ionogel approach is successfully applied without specific adaptation to two state-of-the-art, positive electroactive materials developed for future-generation lithium-ion batteries, namely LiFePO{sub 4} and LiNi{sub 1/3}Mn{sub 1/3}Co{sub 1/3}O{sub 2}.

    Pulsed electron paramagnetic resonance spectroscopy of the photoexcited, metastable triplet state of the oxygen-vacancy center in silicon reveals that the lifetime of the m(s)=±1 sublevels differs significantly from that of the m(s)=0 state. We exploit this significant difference in decay rates to the ground singlet state to achieve nearly ~100% electron-spin polarization within the triplet. We further demonstrate the transfer of a coherent state of the triplet electron spin to, and from, a hyperfine-coupled, nearest-neighbor (29)Si nuclear spin. We measure the coherence time of the (29)Si nuclear spin employed in this operation and find it to be unaffected by the presence of the triplet electron spin and equal to the bulk value measured by nuclear magnetic resonance.

    Full Text Available The authors, key functionaries in the Kerala state public health system, review the communicable disease scenario of the state for the past 4 years, and in the background of the One Health concept, opines that the re-emerged discipline is perfectly in tune with the current challenges of the state. The unique model of Kerala state is witnessing newer challenges in its public health arena: The rapidly increasing migrant workforce from relatively poorer states of India, rapid urbanization and its consequent stress on public health, unsolved issues of urban waste disposal, reemergence of many communicable diseases like malaria, more so, the falciparum type, emergence of many zoonotic diseases like Lyme disease, scrub typhus, and Kyasanur forest disease etc. Conventional zoonotic infections such as anthrax and brucellosis remain potential threat for human health as well. Rabies continued to cause major concern from mortality point of view, as well as major drainer of state’s budget every year. Leptospirosis has remained major burden among the communicable disease for the past 10 years, and the annual incidence ranged from 2 to 7 per 100,000 population. Having a large section of its people working in various agriculture and animal rearing occupations, the state has all risk factors for propagation of Leptospirosis, but lacks interdisciplinary collaboration in its control and prevention area, the author highlights major avenues for collaboration. Japanese encephalitis appeared as an epidemic in 2011 in two of the southern districts in Kerala, one of the districts being famous tourist spot for both humans, as well as migrant birds. There is ample scope for collaborative research on the source of the virus, and in the subsequent years, the disease had been detected in more districts. Lyme disease was reported for the first time in India, from one of the districts in Kerala, promptly investigated by a joint team from Human Public Health and Veterinary

    Spatial patterns of coherent activity across different brain areas have been identified during the resting-state fluctuations of the brain. However, recent studies indicate that resting-state activity is not stationary, but shows complex temporal dynamics. We were interested in the spatiotemporal dynamics of the phase interactions among resting-state fMRI BOLD signals from human subjects. We found that the global phase synchrony of the BOLD signals evolves on a characteristic ultra-slow (synchronized brain regions. Synchronized communities reoccurred intermittently in time and across scanning sessions. We found that the synchronization communities relate to previously defined functional networks known to be engaged in sensory-motor or cognitive function, called resting-state networks (RSNs), including the default mode network, the somato-motor network, the visual network, the auditory network, the cognitive control networks, the self-referential network, and combinations of these and other RSNs. We studied the mechanism originating the observed spatiotemporal synchronization dynamics by using a network model of phase oscillators connected through the brain’s anatomical connectivity estimated using diffusion imaging human data. The model consistently approximates the temporal and spatial synchronization patterns of the empirical data, and reveals that multiple clusters that transiently synchronize and desynchronize emerge from the complex topology of anatomical connections, provided that oscillators are heterogeneous.

    Lyophilization (freeze-drying) is frequently used to stabilize protein therapeutics. However, covalent modifications such as thiol-disulfide exchange and disulfide scrambling can occur even in the solid state. The effects of lyophilization and storage of lyophilized powders on the mechanism and kinetics of thiol-disulfide exchange have not been elucidated and are explored here. Reaction kinetics was monitored in peptides corresponding to tryptic fragments of human growth hormone (T20 + T20-T21 or T20 + cT20-T21) during different stages of lyophilization and during storage of the lyophilized powders at 22°C and ambient RH. The concentrations of reactants and products were determined using RP-HPLC and product identity confirmed using liquid chromatography-mass spectrometry. Loss of native disulfide was observed for the reaction of T20 with both linear (T20-T21) and cyclic (cT20-T21) peptides during the primary drying step; however, the native disulfides were regenerated during secondary drying with no further change till the end of lyophilization. Deviations from Arrhenius parameters predicted from solution studies and the absence of buffer effects during lyophilization suggest that factors such as temperature, initial peptide concentration, buffer type, and concentration do not influence thiol-disulfide exchange during lyophilization. Results from a "cold finger" method used to study peptide adsorption to ice indicate that there is no preferential adsorption to the ice surface and that its presence may not influence disulfide reactivity during primary drying. Overall, reaction rates and product distribution differ for the reaction of T20 with T20-T21 or cT20-T21 in the solid state and aqueous solution, whereas the mechanism of thiol-disulfide remains unchanged. Increased reactivity of the cyclic peptide in the solid state suggests that peptide cyclization does not offer protection against lyophilization and that damage induced by a process stress further affects

    Harmonic compensated synchronous detection (HCSD) is a technique that can be used to measure wideband impedance spectra within seconds based on an input sum-of-sines signal having a frequency spread separated by harmonics. The battery (or other energy storage device) is excited with a sum-of-sines current signal that has a duration of at least one period of the lowest frequency. The voltage response is then captured and synchronously detected at each frequency of interest to determine the impedance spectra. This technique was successfully simulated using a simplified battery model and then verified with commercially available Sanyo lithium-ion cells. Simulations revealed the presence of a start-up transient effect when only one period of the lowest frequency is included in the excitation signal. This transient effect appears to only influence the low-frequency impedance measurements and can be reduced when a longer input signal is used. Furthermore, lithium-ion cell testing has indicated that the transient effect does not seem to impact the charge transfer resistance in the mid-frequency region. The degradation rates for the charge transfer resistance measured from the HCSD technique were very similar to the changes observed from standardized impedance spectroscopy methods. Results from these studies, therefore, indicate that HCSD is a viable, rapid alternative approach to acquiring impedance spectra.

    Past nuclear accidents, such as Chernobyl, resulted in a large release of radionuclides into the atmosphere. Radiological assessment of the vicinity of the site of the incident is vital to assess the exposure levels and dose received by the population and workers. Therefore, it is critical to thoroughly understand the situation and risks associated with a particular event in a timely manner in order to properly manage the event. Current atmospheric radiological assessments of alpha emitting radioisotopes include acquiring large quantities of air samples, chemical separation of radionuclides, sample mounting, counting through alpha spectrometry, and analysis of the data. The existing methodology is effective, but time consuming and labor intensive. Autoradiography, and the properties of phosphor imaging films, may be used as an additional technique to facilitate and expedite the alpha analysis process in these types of situations. Although autoradiography is not as sensitive to alpha radiation as alpha spectrometry, autoradiography may benefit alpha analysis by providing information about the activity as well as the spatial distribution of radioactivity in the sample under investigation. The objective for this research was to develop an efficient method for quantification and visualization of air filter samples taken in the aftermath of a nuclear emergency through autoradiography using 241Am and 239Pu tracers. Samples containing varying activities of either 241Am or 239Pu tracers were produced through microprecipitation and assayed by alpha spectroscopy. The samples were subsequently imaged and an activity calibration curve was produced by comparing the digital light units recorded from the image to the known activity of the source. The usefulness of different phosphor screens was examined by exposing each type of film to the same standard nuclide for varying quantities of time. Unknown activity samples created through microprecipiation containing activities of

    To report the availability, utilization, and quality of emergency obstetric care (EmOC) services in Bauchi State, Nigeria. Between June and July 2012, a cross-sectional survey of health facilities was conducted. Data on the performance of EmOC services between June 2011 and May 2012 were obtained from records of 20 general hospitals and 39 primary healthcare centers providing delivery services. Additionally, structured interviews with facility managers were conducted. Only 6 (10.2%) of the 59 facilities met the UN requirements for EmOC centers. None of the three senatorial zones in Bauchi State had the minimum acceptable number of five EmOC facilities per 500 000 population. Overall, 10 517 (4.4%) of the estimated 239 930 annual births took place in EmOC facilities. Cesarean delivery accounted for 3.6% (n=380) of the 10 517 births occurring in EmOC facilities and 0.2% of the 239 930 expected live births. Only 1416 (3.9%) of the expected 35 990 obstetric complications were managed in EmOC facilities. Overall, 45 (3.2%) of 1416 women with major direct obstetric complications treated at EmOC facilities died. Among 379 maternal deaths, 317 (83.6%) were attributable to major direct obstetric complications. Availability, utilization, and quality of EmOC services in Bauchi State, Nigeria, are suboptimal. The health system's capacity to manage emergency obstetric complications needs to be strengthened. Copyright © 2014 International Federation of Gynecology and Obstetrics. All rights reserved.

    Brain fluctuations at rest are not random but are structured in spatial patterns of correlated activity across different brain areas. The question of how resting-state functional connectivity (FC) emerges from the brain's anatomical connections has motivated several experimental and computational studies to understand structure-function relationships. However, the mechanistic origin of resting state is obscured by large-scale models' complexity, and a close structure-function relation is still an open problem. Thus, a realistic but simple enough description of relevant brain dynamics is needed. Here, we derived a dynamic mean field model that consistently summarizes the realistic dynamics of a detailed spiking and conductance-based synaptic large-scale network, in which connectivity is constrained by diffusion imaging data from human subjects. The dynamic mean field approximates the ensemble dynamics, whose temporal evolution is dominated by the longest time scale of the system. With this reduction, we demonstrated that FC emerges as structured linear fluctuations around a stable low firing activity state close to destabilization. Moreover, the model can be further and crucially simplified into a set of motion equations for statistical moments, providing a direct analytical link between anatomical structure, neural network dynamics, and FC. Our study suggests that FC arises from noise propagation and dynamical slowing down of fluctuations in an anatomically constrained dynamical system. Altogether, the reduction from spiking models to statistical moments presented here provides a new framework to explicitly understand the building up of FC through neuronal dynamics underpinned by anatomical connections and to drive hypotheses in task-evoked studies and for clinical applications.

    A study has been carried out on the feasibility of using solid-state phase transitions for thermal energy storage. As part of this study a literature search was made to identify the most promising types of compounds and a synthesis program was carried out to prepare certain of these substances. In addition a large number of compounds for testing were obtained from commercial sources. All of the compounds were screened for transitions using a Perkin Elmer DSC-1B differential scanning calorimeter. From this program seven compounds were found that have transition energies from 20-30 cal/g in the temperatre range of 335-405 K. The most promising compound found is 5-norbornene-2,3-dicarboxylic acid anhydride having a transition of 22.6 cal/g at 366 K and an estimated cost of peparation of $0.40/lb..

    Full Text Available Despite the development of on-farm anaerobic digestion as a process for making profitable use of animal by-products, factors leading to the inactivation of pathogenic bacteria during storage of digestates remain poorly described. Here, a microcosm approach was used to evaluate the persistence of three pathogenic bacteria (Salmonella enterica Derby, Campylobacter coli and Listeria monocytogenes in digestates from farms, stored for later land spreading. Nine samples, including raw digestates, liquid fractions of digestate and composted digestates, were inoculated with each pathogen and maintained for 40 days at 24°C. Concentrations of pathogens were monitored using culture and qPCR methods. The persistence of L. monocytogenes, detected up to 20 days after inoculation, was higher than that of Salmonella Derby, detected for 7-20 days, and of C. coli (not detected after 7 days. In some digestates, the concentration of the pathogens by qPCR assay was several orders of magnitude higher than the concentration of culturable cells, suggesting a potential loss of culturability and induction of Viable but Non-Culturable (VBNC state. The potential VBNC state which was generally not observed in the same digestate for the three pathogens, occurred more frequently for C. coli and L. monocytogenes than for Salmonella Derby. Composting a digestate reduced the persistence of seeded L. monocytogenes but promoted the maintenance of Salmonella Derby. The effect of NH4+/NH3 on the culturability of C. coli and Salmonella Derby was also shown.The loss of culturability may be the underlying mechanism for the regrowth of pathogens. We have also demonstrated the importance of using molecular tools to monitor pathogens in environmental samples since culture methods may underestimate cell concentration. Our results underline the importance of considering VBNC cells when evaluating the sanitary effect of an anaerobic digestion process and the persistence of pathogens during

    To determine the relationship between stress indicators and state anxiety among pediatric emergency department (ED) patients, as a background to develop appropriate psychoeducational and behavioral interventions. Patients with nonchronic conditions aged 10 to 18 years completed questionnaires assessing demographics; (8) life stressors (LSs), such as death in family and marital separation/divorce; (10) anticipatory stressors (ASs) such as fear of needles, blood, or undressing; and the State Trait Anxiety Inventory for Children (a 20-item validated tool). One hundred patients completed the study: the mean age was 13.3 years; 56% were female; and 90% were Latino patients. Notable life stressors (mean, 1.83) included: change in school location (24%), change in school performance (29%), death in family (33%), and marital separation/divorce (48%). Common AS (mean, 4.76) included worry about shots (33%), strangers (41%), talking about personal problems (44%), separation from parents (51%), undressing (56%), hospitalization (57%), and pain (73%). Significant correlations were found between age and state anxiety (r, -0.21; P anxiety (r, 0.20; P anxiety (36%) were more likely to be in the ED with a complaint of pain and/or trauma, had significantly more AS (t, 2.1; P anxiety. The ED experience produces fear/anxiety, particularly in younger patients with a chief complaint of pain and/or trauma. Findings may lead to the development of psychoeducational and behavioral interventions that focus on anxiety reduction.

    Quantum repeaters are critical components for distributing entanglement over long distances in presence of unavoidable optical losses during transmission. Stimulated by Duan-Lukin-Cirac-Zoller protocol, many improved quantum-repeater protocols based on quantum memories have been proposed, which commonly focus on the entanglement-distribution rate. Among these protocols, the elimination of multi-photons (multi-photon-pairs) and the use of multimode quantum memory are demonstrated to have the ability to greatly improve the entanglement-distribution rate. Here, we demonstrate the storage of deterministic single photons emitted from a quantum dot in a polarization-maintaining solid-state quantum memory; in addition, multi-temporal-mode memory with 1, 20 and 100 narrow single-photon pulses is also demonstrated. Multi-photons are eliminated, and only one photon at most is contained in each pulse. Moreover, the solid-state properties of both sub-systems make this configuration more stable and easier to be scalable. Our work will be helpful in the construction of efficient quantum repeaters based on all-solid-state devices.

    More than 200 studies of warning systems and warning response were reviewed for this social science perspective and state-of-the-art assessment of communication of emergency public warnings. The major findings are as follows. First, variations in the nature and content of warnings have a large impact on whether or not the public heeds the warning. Relevant factors include the warning source; warning channel; the consistency, credibility, accuracy, and understandability of the message; and the warning frequency. Second, characteristics of the population receiving the warning affect warning response. These include social characteristics such as gender, ethnicity and age, social setting characteristics such as stage of life or family context, psychological characteristics such as fatalism or risk perception, and knowledge characteristics such as experience or training. Third, many current myths about public response to emergency warning are at odds with knowledge derived from field investigations. Some of these myths include the keep it simple'' notion, the cry wolf'' syndrome, public panic and hysteria, and those concerning public willingness to respond to warnings. Finally, different methods of warning the public are not equally effective at providing an alert and notification in different physical and social settings. Most systems can provide a warning given three or more hours of available warning time. Special systems such as tone-alert radios are needed to provide rapid warning. 235 refs., 8 figs., 2 tabs.

    Controlling quantum critical phenomena in strongly correlated electron systems, which emerge in the neighborhood of a quantum phase transition, is a major challenge in modern condensed matter physics. Quantum critical phenomena are generated from the delicate balance between long-range order and its quantum fluctuation. So far, the nature of quantum phase transitions has been investigated by changing a limited number of external parameters such as pressure and magnetic field. We propose a new approach for investigating quantum criticality by changing the strength of quantum fluctuation that is controlled by the dimensional crossover in metallic quantum well (QW) structures of strongly correlated oxides. With reducing layer thickness to the critical thickness of metal-insulator transition, crossover from a Fermi liquid to a non-Fermi liquid has clearly been observed in the metallic QW of SrVO3 by in situ angle-resolved photoemission spectroscopy. Non-Fermi liquid behavior with the critical exponent α = 1 is found to emerge in the two-dimensional limit of the metallic QW states, indicating that a quantum critical point exists in the neighborhood of the thickness-dependent Mott transition. These results suggest that artificial QW structures provide a unique platform for investigating novel quantum phenomena in strongly correlated oxides in a controllable fashion.

    Objective of the current study is to provide nationally representative estimates of hospital based emergency department (ED) visits attributed to dental implant failures in the United States. The Nationwide Emergency Department sample for the years 2008-2010 was used. All ED visits with a diagnosis of "dental implant failures" were selected for analysis. Patient demographics were examined. Outcomes of interest included disposition status following the ED visit and ED charges. During the study period, a total of 1200 ED visits were due to dental implant failures. Most ED visits with dental implant failures occurred among those aged dental implant occurred in 31.7% of patients while post-osseointegration mechanical failure of dental implant occurred in 30.4% of patients. Following an ED visit, 82.8% were discharged routinely and 13.3% of patients were admitted as in-patients into the same hospital following the ED visit. The mean ED charge per visit was $1167. Highest proportions of these ED visits were comprised of those aged implant failures. Copyright © 2016 Elsevier Inc. All rights reserved.

    This study investigates the epidemiology of cheerleading injuries to children in the United States. Data were analyzed from the National Electronic Injury Surveillance System for children 5 through 18 years of age treated in US emergency departments for cheerleading injuries from 1990 through 2012. An estimated 497 095 children ages 5 to 18 years were treated in US emergency departments for a cheerleading injury during the 23-year study period, averaging 21 613 injured children per year. From 1990 to 2012, the annual cheerleading injury rate increased significantly by 189.1%; and from 2001 to 2012, the annual rate of cheerleading-related concussion/closed head injury increased significantly by 290.9%. Falls were the most common mechanism of injury (29.4%) and were more likely to lead to hospitalization (relative risk = 2.47; 95% confidence interval = 1.67-3.68) compared with other injury mechanisms. The rising number and rate of pediatric cheerleading injuries underscore the need for increased efforts to prevent these injuries.

  18. On the emergence of natural singularities and state transitions in living patterns

    CERN Document Server

    Dobay, Akos

    2014-01-01

    As far as human perceptions and rational thinking are concerned, contradictions constitute a non negligible part of our reality. We often refer to these phenomena, in a more informal way, as the chicken or the egg causality dilemma. However, it is not clear whether the chicken or the egg dilemma exists only within the scope of our perceptions, or contradictions have a deeper meaning towards our understanding of reality. Here we argue that if there is an element of reality such that can be adequately described in terms of the chicken or the egg dilemma, then it might lead to a spontaneous symmetry breaking by creating an alternate entity, capable of ultimately separating the chicken from the egg. We propose a formalism to describe such mechanism and discuss how it can be applied to phenomena to describe the natural emergence of singularities and state transitions in living systems.

    A number of diverse approaches and sciences can contribute to a robust understanding of the I. state, II. vulnerabilities, and III. opportunities for soil carbon in context of its potential contributions to the atmospheric C budget. Soil state refers to the current C stock of a given site, region, or ecosystem/landuse type. Soil vulnerabilities refers to the forms and bioreactivity of C stocks, which determine how soil C might respond to climate, disturbance, and landuse perturbations. Opportunities refer to the potential for soils in their current state to increase capacity for and rate of C storage under future conditions, thereby impacting atmospheric C budgets. In order to capture the state, vulnerability, and opportunities for soil C, a robust C accounting scheme must include at least three science needs: (1) a user-friendly and dynamic database with transparent, shared coding in which data layers of solid, liquid, and gaseous phases share relational metadata and allow for changes over time (2) a framework to characterize the capacity and reactivity of different soil types based on climate, historic, and landscape factors (3) a framework to characterize landuse practices and their impact on physical state, capacity/reactivity, and potential for C change. In order to transfer our science information to practicable implementations for land policies, societal and social needs must also include: (1) metrics for landowners and policy experts to recognize conditions of vulnerability or opportunity (2)communication schemes for accessing salient outcomes of the science. Importantly, there stands an opportunity for contributions of data, model code, and conceptual frameworks in which scientists, educators, and decision-makers can become citizens of a shared, scrutinized database that contributes to a dynamic, improved understanding of our soil system.

    2016-01-01

    Background: There are little demographic data on finger dislocation injuries. This study examines the epidemiological characteristics of patients presenting for emergency care of finger dislocations within the United States. Methods: The National Electronic Injury Surveillance System was queried for finger dislocation injuries treated in US emergency departments between 2004 and 2008. Weighted estimates, in conjunction with Census data, were used to analyze patient demographics, injury locales, and incidence rates within and between, demographic groups. Results: During the 5-year study period, an estimated 166 561 finger dislocations were treated in 1 499 222 917 person-years: an incidence rate of 11.11 per 100 000 person-years. Males were predominantly affected (78.7%) at an incidence rate of 17.8 per 100 000. The rate in females was 4.65 per 100 000 person-years. Most dislocations occurred in the 15- to 19-year age group (38.6 dislocations per 100 000 person-years). Among racial groups, blacks (16.8) were affected more than whites (7.72) or patients characterized as “other” (4.90). In terms of injury venue, 35.9% of cases took place at a sporting or recreational facility. In addition, 44.7% of sports-related dislocations occurred while playing either basketball or football. Conclusions: In the United States, finger dislocations appear to occur most often in black males 15 to 19 years of age and among sports participants, particularly basketball and football players.

    Skaer, Tracy L; Nwude, Azuka C

    2016-06-01

    Rising mortality rates, increased opioid prescription abuse, and a perceived need to provide practitioners with structured guidance in opioid prescribing have prompted the Washington State Legislature to establish new legal standards of practice regarding chronic non-cancer pain management. Clinicians are required to conduct a detailed physical examination and health history prior to treatment. Risk assessments for abuse and detailed periodic reviews of treatment are required at least every 6 months. Those considered "high risk" or who have significant psychiatric comorbidities will be required to sign and follow a written agreement or pain contract, obtain their pain prescriptions from a single provider, and submit to biological drug screening. Unless an exemption exists, patients prescribed > 120 mg of morphine-equivalents daily, considered severe pain nonresponders, necessitating dosage escalation, diagnosed with multifaceted mental health-related comorbidities, demonstrating diagnostic ambiguity, and/or requiring significant treatment individualization are referred to a pain specialist. Episodic care settings should refrain from supplying opioids to chronic pain patients whenever possible. The ER is for Emergencies coalition instituted the Seven Best Practices program throughout the state to reduce unnecessary visits, coordinate prescribing practice, reduce Medicaid expenditures, and improve overall patient care. The state reported approximately $33.65 million in savings in 2013 through the use of these practices and converting Medicaid participants from fee-for-service to managed care plans. Similar legislation to complement clinical practice guidelines is expected to be enacted in other states. It is vital that practitioners comprehend the new guidelines and make appropriate adjustments in their opioid prescribing habits. © 2015 World Institute of Pain.

    This report presents final technical results for the project Simulation Framework for Regional Geologic CO{sub 2} Storage Infrastructure along Arches Province of the Midwest United States. The Arches Simulation project was a three year effort designed to develop a simulation framework for regional geologic carbon dioxide (CO{sub 2}) storage infrastructure along the Arches Province through development of a geologic model and advanced reservoir simulations of large-scale CO{sub 2} storage. The project included five major technical tasks: (1) compilation of geologic, hydraulic and injection data on Mount Simon, (2) development of model framework and parameters, (3) preliminary variable density flow simulations, (4) multi-phase model runs of regional storage scenarios, and (5) implications for regional storage feasibility. The Arches Province is an informal region in northeastern Indiana, northern Kentucky, western Ohio, and southern Michigan where sedimentary rock formations form broad arch and platform structures. In the province, the Mount Simon sandstone is an appealing deep saline formation for CO{sub 2} storage because of the intersection of reservoir thickness and permeability. Many CO{sub 2} sources are located in proximity to the Arches Province, and the area is adjacent to coal fired power plants along the Ohio River Valley corridor. Geophysical well logs, rock samples, drilling logs, and geotechnical tests were evaluated for a 500,000 km{sup 2} study area centered on the Arches Province. Hydraulic parameters and historical operational information was also compiled from Mount Simon wastewater injection wells in the region. This information was integrated into a geocellular model that depicts the parameters and conditions in a numerical array. The geologic and hydraulic data were integrated into a three-dimensional grid of porosity and permeability, which are key parameters regarding fluid flow and pressure buildup due to CO{sub 2} injection.

    Landfills are commonly the final respository for a heterogeneous mixture of waste from residential, commercial, and industrial sources. The use of landfills as a means of waste disposal will likely increase as the global population increases and nations develop. Thus, landfills receiving such waste have the potential to produce leachate containing numerous organic chemicals including contaminants of emerging concern (CECs) such as pharmaceuticals, personal care products, and hormones. This leachate is often discharged to pathways that lead directly (e.g. groundwater, streams) or indirectly (e.g. wastewater treament plants) to the environment. Limited research, however, has been conducted regarding the characterisation of landfill leachate for CECs.To provide the first national-scale assessment of CECs in landfill leachate across the United States, fresh leachate samples (i.e. prior to onsite treatment) from 19 landfills in 16 states were collected in 2011 and analysed for 202 CECs [1]. The targeted CECs were selected for analysis because they were expected to be persistent in the environment; are used, excreted, or disposed of in substantial quantities; may have human or environmental health effects; or are potential indicators of environmentally relevant classes of chemicals or source materials.

    Ethics is a discipline, which primarily deals with what is moral and immoral behavior. Public Health Ethics is translation of ethical theories and concepts into practice to address complex multidimensional public health problems. The primary purpose of this paper was to conduct a narrative literature review-addressing role of ethics in developing curriculum in programs and schools of public health, ethics-related instruction in schools and programs of public health and the role of ethics in developing a competent public health workforce. An open search of various health databases including Google scholar and Ebscohost yielded 15 articles related to use of ethics in public health practice or public health training and the salient features were reported. Results indicated a variable amount of ethics' related training in schools and programs of public health along with public health practitioner training across the nation. Bioethics, medical ethics and public health ethics were found to be subspecialties' needing separate ethical frameworks to guide decision making. Ethics based curricular and non-curricular training for emerging public health professionals from schools and programs of public health in the United States is extremely essential. In the current age of public health challenges faced in the United States and globally, to have an ethically untrained public health force is arguably, immoral and unethical and jeopardizes population health. There is an urgent need to develop innovative ethic based curriculums in academia as well as finding effective means to translate these curricular competencies into public health practice.

    Nuclear spins are promising candidates for quantum information processing because their good isolation from the environment precludes the rapid loss of quantum coherence. Many strategies have been developed to further extend their decoherence times. Some of them make use of decoupling techniques based on the Carr-Purcell and Carr-Purcell-Meiboom-Gill pulse sequences. In many cases, when applied to inhomogeneous samples, they yield a magnetization decay much slower than that of the Hahn echo. However, we have proved that these decays cannot be associated with longer decoherence times, as coherences remain frozen. They result from coherences recovered after their storage as local polarization and thus they can be used as memories. We show here how this freezing of the coherent state, which can subsequently be recovered after times longer than the natural decoherence time of the system, can be generated in a controlled way with the use of field gradients. A similar behaviour of homogeneous samples in inhomogeneous fields is demonstrated. It is emphasized that the effects of inhomogeneities in solid-state nuclear magnetic resonance, independently of their origin, should not be disregarded, as they play a crucial role in multipulse sequences.

    This study aimed to estimate the incidence of emergency department (ED) visits in the neonatal period in a nationally representative sample and to examine variation by race. The National Hospital Ambulatory Medical Care Survey is a nationally representative survey of utilization of ambulatory care services including EDs. We studied all ED visits for patients who were younger than 28 days old from 2003 to 2008. Using the national birth certificate data, we calculated the visit rates by race. Emergency department visits were also characterized by age, insurance status, diagnosis category, region, and hospital type (safety-net vs non-safety-net hospitals). There was an average of 320,540 neonatal ED visits in the United States per year, with an estimated 7.6% of births visiting the ED within 28 days. Estimated rates of ED visits were highest among non-Hispanic blacks, with 14.4% (95% confidence interval [CI], 10.0-19.2) of newborns having an ED visit in the neonatal period, compared with 6.7% (95% CI, 4.9-7.2) for whites and 7.7% (95% CI, 5.7-9.8) for Hispanics. Hispanic and black neonates were more likely to be seen in safety-net hospitals (75.8%-78.2%) than white (57.1%) patients (P = 0.004). In this first nationally representative study of neonatal visits to the ED, visits were common, with the highest rates in non-Hispanic blacks. Hispanic and black neonates were more commonly seen in safety-net hospitals. Reasons for high visit rates deserve further study to determine whether hospital discharge practices and/or access to primary care are contributing factors.

    Infectious hematopoietic necrosis virus (IHNV) occurs in North America as 3 major phylogenetic groups designated U, M, and L. In coastal Washington State, IHNV has historically consisted of U genogroup viruses found predominantly in sockeye salmon Oncorhynchus nerka. M genogroup IHNV, which has host-specific virulence for rainbow and steelhead trout O. mykiss, was detected only once in coastal Washington prior to 2007, in an epidemic among juvenile steelhead trout in 1997. Beginning in 2007 and continuing through 2011, there were 8 IHNV epidemics in juvenile steelhead trout, involving 7 different fish culture facilities in 4 separate watersheds. During the same time period, IHNV was also detected in asymptomatic adult steelhead trout from 6 coastal watersheds. Genetic typing of 283 recent virus isolates from coastal Washington revealed that the great majority were in the M genogroup of IHNV and that there were 2 distinct waves of viral emergence between the years 2007 and 2011. IHNV type mG110M was dominant in coastal steelhead trout during 2007 to 2009, and type mG139M was dominant between 2010 and 2011. Phylogenetic analysis of viral isolates indicated that all coastal M genogroup viruses detected in 1997 and 2007 to 2011 were part of the MD subgroup and that several novel genetic variants related to the dominant types arose in the coastal sites. Comparison of spatial and temporal incidence of coastal MD viruses with that of the rest of the Pacific Northwest indicated that the likely source of the emergent viruses was Columbia River Basin steelhead trout. 

  16. Vaccine escape recombinants emerge after pneumococcal vaccination in the United States.

    Full Text Available The heptavalent pneumococcal conjugate vaccine (PCV7 was introduced in the United States (US in 2000 and has significantly reduced invasive pneumococcal disease; however, the incidence of nonvaccine serotype invasive disease, particularly due to serotype 19A, has increased. The serotype 19A increase can be explained in part by expansion of a genotype that has been circulating in the US prior to vaccine implementation (and other countries since at least 1990, but also by the emergence of a novel "vaccine escape recombinant" pneumococcal strain. This strain has a genotype that previously was only associated with vaccine serotype 4, but now expresses a nonvaccine serotype 19A capsule. Based on prior evidence for capsular switching by recombination at the capsular locus, the genetic event that resulted in this novel serotype/genotype combination might be identifiable from the DNA sequence of individual pneumococcal strains. Therefore, the aim of this study was to characterise the putative recombinational event(s at the capsular locus that resulted in the change from a vaccine to a nonvaccine capsular type. Sequencing the capsular locus flanking regions of 51 vaccine escape (progeny, recipient, and putative donor pneumococci revealed a 39 kb recombinational fragment, which included the capsular locus, flanking regions, and two adjacent penicillin-binding proteins, and thus resulted in a capsular switch and penicillin nonsusceptibility in a single genetic event. Since 2003, 37 such vaccine escape strains have been detected, some of which had evolved further. Furthermore, two new types of serotype 19A vaccine escape strains emerged in 2005. To our knowledge, this is the first time a single recombinational event has been documented in vivo that resulted in both a change of serotype and penicillin nonsusceptibility. Vaccine escape by genetic recombination at the capsular locus has the potential to reduce PCV7 effectiveness in the longer term.

    Concentrated solar thermal power generation is becoming a very attractive renewable energy production system among all the different renewable options, as it has have a better potential for dispatchability. This dispatchability is inevitably linked with an efficient and cost-effective thermal storage system. Thus, of all components, thermal storage is a key one. However, it is also one of the less developed. Only a few plants in the world have tested high temperature thermal energy storage systems. In this paper, the different storage concepts are reviewed and classified. All materials considered in literature or plants are listed. And finally, modellization of such systems is reviewed.

    The purpose of this survey and record review was to characterize emergency department management of unprovoked seizures and status epilepticus in children in Illinois. The survey was sent to 119 participating emergency departments in the Emergency Medical Services for Children program; responses were received from 103 (88% response rate). Only 44% of the emergency departments had a documented protocol for seizure management. Only 12% of emergency departments had child neurology consultation available at all times. Record review showed that 58% of patients were discharged home, 26% were transferred to another institution, and 10% were admitted to a non-intensive care unit setting. Ninety percent of patients were treated with anticonvulsants. Seizure education was provided by the primary emergency department nurse (97%) and the treating physician (79%). This project demonstrated strengths and weaknesses in the current management of pediatric seizure patients in Illinois emergency departments. © The Author(s) 2015.

    Both sheep and goat pox are contagious viral diseases and affect small ruminants and are caused by sheep pox virus and goat pox virus respectively that belong to genus Capripoxvirus of Poxviridae family. Huge economic losses emanating from the disease outbreaks are the results of the wool and hide damage, subsequent production losses and also the morbidities and mortalities associated with the disease. This communication highlights clinico-epidemiological observations from the two sheep pox and one goat pox outbreaks. Grossly, multisystemic nodular lesions, mucopurulent nasal discharges and respiratory symptoms were observed in the affected animals. The morbidity, mortality and case fatality rates were 5.18%, 2.45% and 32.37%, respectively. Histopathological, haematological, molecular and serological techniques and also isolation of virus in embryonated chicken eggs were used for the diagnosis of the diseases. The spatial distribution of the disease signifies the role of common pasturelands used for grazing the animals while temporally all three outbreaks occurred in winters and were probably associated with cold stress and fodder scarcity. This is the first recorded report of Capripoxvirus infection in recent times and it highlights the disease as one of the emerging diseases in the northern state of Himachal Pradesh in India. © 2010 Blackwell Verlag GmbH.

    Background Prior research has documented factors associated with non-traumatic dental condition (NTDC) visits to emergency departments (EDs), but little is known about the care received by patients in EDs for NTDC visits. Objective We examined national trends in prescription of analgesics and antibiotics in EDs for NTDC visits in the United States. Research Design We analyzed data from the National Hospital Ambulatory Medical Care survey for 1997 to 2007. We used a multivariable logistic regression model to examine factors associated with receiving analgesics and antibiotics for NTDC visit in EDs. Results Overall 74% received at least one analgesic, 56% at least one antibiotic and 13% received no medication at all during an NTDC visit to the ED. The prescription of medications at EDs for NTDC visits steadily increased over time for analgesics (OR=1.11/year, p=analgesics. Conclusions Nationally, analgesic and antibiotic prescriptions for NTDC visits to EDs have increased substantially over time. Self-pay patients had significantly higher odds of being prescribed antibiotics. Adults over 53 years and especially those 73 years and older had significantly lower odds of receiving analgesics in EDs for NTDC visits. PMID:22584886

  5. The Resource Hazards Model for the Critical Infrastructure of the State Emergency Management Process

    2014-08-01

    Full Text Available This paper presents an investigation of the relevant factors related to the construction of a resource model which is designed to be useful in the management processes of the operation of critical infrastructure (CI for state emergencies. The genesis of the research lay in the perceived need for effective protection of multidimensional CI methodologies, and it was influenced by the nature of the physical characteristics of the available resources. It was necessary to establish a clear structure and well defined objectives and to assess the functional and structural resources required, as well as the potential relational susceptibilities deriving from a number of possible threats and the possible seriousness of a specific range of incidents and their possible consequences. The interdependence of CI stocks is shown by the use of tables of resource classes. The dynamics of the interaction of CI resources are modeled by examining how using clusters of potential risks can at any given time create a class of compounds related to susceptibilities and threats to the resources. As a result, the model can be used to conduct multi-dimensional risk calculations for crisis management CI resource configurations.

  6. Telehealth in older adults with cancer in the United States: The emerging use of wearable sensors.

    Shen, John; Naeim, Arash

    2017-11-01

    As the aging and cancer populations in the world continue to increase, the need for complements to traditional geriatric assessments and the logical incorporation of fast and reliable telehealth tools have become interlinked. In the United States, studies examining the use of telehealth for chronic disease management have shown promising results in small groups. The implementation of health technology on a broader scale requires older adults to both accept and adapt such innovation into routine medical care. Though the commercial and recreational use of new technology has increased in older individuals, the transition into creating a smart and connected home that can interface with both patients and healthcare professionals is in its early phases. Current limitations include an inherent digital divide, as well as concerns regarding privacy, data volume, rapid change, cost and reimbursement. The emergence of low-cost, high-fidelity wearable sensors with a spectrum of clinical utility may be the key to increased use and adaptation by older adults. An opportunity to utilize wearable sensors for objective and real-time assessment of older patients with cancer for baseline functional status and treatment toxicity may be on the horizon.

    To evaluate the Public Health Emergency Preparedness (PHEP) program's progress toward meeting public health preparedness capability standards in state, local, and territorial health departments. All 62 PHEP awardees completed the Centers for Disease Control and Prevention's self-administered PHEP Impact Assessment as part of program review measuring public health preparedness capability before September 11, 2001 (9/11), and in 2014. We collected additional self-reported capability self-assessments from 2016. We analyzed trends in congressional funding for public health preparedness from 2001 to 2016. Before 9/11, most PHEP awardees reported limited preparedness capabilities, but considerable progress was reported by 2016. The number of jurisdictions reporting established capability functions within the countermeasures and mitigation domain had the largest increase, almost 200%, by 2014. However, more than 20% of jurisdictions still reported underdeveloped coordination between the health system and public health agencies in 2016. Challenges and barriers to building PHEP capabilities included lack of trained personnel, plans, and sustained resources. Considerable progress in public health preparedness capability was observed from before 9/11 to 2016. Support, sustainment, and advancement of public health preparedness capability is critical to ensure a strong public health infrastructure.

  8. Optimal Scheduling and Real-Time State-of-Charge Management of Energy Storage System for Frequency Regulation

    2016-11-01

    Full Text Available An energy storage system (ESS in a power system facilitates tasks such as renewable integration, peak shaving, and the use of ancillary services. Among the various functions of an ESS, this study focused on frequency regulation (or secondary reserve. This paper presents an optimal scheduling algorithm for frequency regulation by an ESS. This algorithm determines the bidding capacity and base point of an ESS in each operational period to achieve the maximum profit within a stable state-of-charge (SOC range. However, the charging/discharging efficiency of an ESS causes SOC errors whenever the ESS performs frequency regulation. With an increase in SOC errors, the ESS cannot respond to an automatic generation control (AGC signal. This situation results in low ESS performance scores, and finally, the ESS is disqualified from performing frequency regulation. This paper also presents a real-time SOC management algorithm aimed at solving the SOC error problem in real-time operations. This algorithm compensates for SOC errors by changing the base point of the ESS. The optimal scheduling algorithm is implemented in MATLAB by using the particle swarm optimization (PSO method. In addition, changes in the SOC when the ESS performs frequency regulation in a real-time operation are confirmed using the PSCAD/EMTDC tool. The simulation results show that the optimal scheduling algorithm manages the SOC more efficiently than a commonly employed planning method. In addition, the proposed real-time SOC management algorithm is confirmed to be capable of performing SOC recovery.

    The project site was identified as an abandoned Underground Storage Tank (UST) to be closed under the Department of Energy/Nevada Operations Office (DOE/NV) Environmental Restoration Division (ERD) Program during Fiscal Year 1993. The United States Environmental Protection Agency (EPA) requires that before permanent closure is completed an assessment of the site must take place. The Nevada Division of Environmental Protection (NDEP) requires assessment and corrective actions for a petroleum substance in the soil which exceeds 100 milligrams per kilogram (mg/kg). Subsequent to the tank removal, a hydrocarbon release was identified at the site. The release was reported to the NDEP by DOE/NV on November 30, 1993. Nevada Division of Environmental Management (NDEM) Case Number H931130E was assigned. This final closure report documents the assessment and corrective actions taken for the hydrocarbon release identified at the site. The Notification of Closure, EPA Form 7530-1 dated March 22, 1994, is provided in Appendix A. A 45-day report documenting the notification for a hydrocarbon release was submitted to NDEP on April 6, 1994.

    2005-11-01

    This article attends to a broad range of practically significant employee motivations and provides insight into how to enhance individual-level performance by examining individual-level state goal orientation emergence in organizational work groups. Leadership and multilevel climate processes are theorized to parallel each dimension of state goal orientation to cue and ultimately induce the corresponding achievement focus among individual work group members. It is argued that the patterns of leader behavior, which elucidate the leader's achievement priority, shape group members' psychological and work group climate to embody this priority. Resulting multilevel climate perceptions signal and compel group members to adopt the ascribed form of state goal orientation. The quality of the leader-member exchange relationship is viewed as a means to clarify leader messages in the formation of group members' psychological climate and internalize these cues in the emergence of state goal orientation. Considerations for future research and practice are discussed. ((c) 2005 APA, all rights reserved).

    Full Text Available Purpose: Smartphone technology offers a multitude of applications (apps that provide a wide range of functions for healthcare professionals. Medical trainees are early adopters of this technology, but how they use smartphones in clinical care remains unclear. Our objective was to further characterize smartphone use by medical trainees at two United States academic institutions, as well as their prior training in the clinical use of smartphones. Methods: In 2014, we surveyed 347 internal medicine and emergency medicine resident physicians at the University of Utah and Brigham and Women’s Hospital about their smartphone use and prior training experiences. Scores (0%–100% were calculated to assess the frequency of their use of general features (email, text and patient-specific apps, and the results were compared according to resident level and program using the Mann-Whitney U-test. Results: A total of 184 residents responded (response rate, 53.0%. The average score for using general features, 14.4/20 (72.2% was significantly higher than the average score for using patient-specific features and apps, 14.1/44 (33.0%, P<0.001. The average scores for the use of general features, were significantly higher for year 3–4 residents, 15.0/20 (75.1% than year 1–2 residents, 14.1/20 (70.5%, P=0.035, and for internal medicine residents, 14.9/20 (74.6% in comparison to emergency medicine residents, 12.9/20 (64.3%, P= 0.001. The average score reflecting the use of patient-specific apps was significantly higher for year 3–4 residents, 16.1/44 (36.5% than for year 1–2 residents, 13.7/44 (31.1%; P=0.044. Only 21.7% of respondents had received prior training in clinical smartphone use. Conclusion: Residents used smartphones for general features more frequently than for patient-specific features, but patient-specific use increased with training. Few residents have received prior training in the clinical use of smartphones.

    The American Society of Anesthesiologist recommends peripheral physiological monitoring during general anesthesia, which offers no information regarding the effects of anesthetics on the brain. Since no "gold standard" method exists for this evaluation, such a technique is needed to ensure patient comfort, procedure quality and safety. In this study we investigated functional near infrared spectroscopy (fNIRS) as possible monitor of anesthetic effects on the prefrontal cortex. Anesthetic drugs, such as sevoflurane, suppress the cerebral metabolism and alter the cerebral blood flow. We hypothesize that fNIRS derived features carry information on the effects of anesthetics on the prefrontal cortex (PFC) that can be used for the classification of the anesthetized state. In this study, patients were continuously monitored using fNIRS, BIS and standard monitoring during surgical procedures under sevoflurane general anesthesia. Maintenance and emergence states were identified and fNIRS features were identified and compared between states. Linear and non-linear machine learning algorithms were investigated as methods for the classification of maintenance/emergence. The results show that changes in oxygenated (HbO2) and deoxygenated hemoglobin (HHb) concentration and blood volume measured by fNIRS were associated with the transition between maintenance and emergence that occurs as a result of sevoflurane washout. We observed that during maintenance the signal is relatively more stable than during emergence. Maintenance and emergence states were classified with 94.7% accuracy with a non-linear model using the locally derived mean total hemoglobin, standard deviation of HbO2, minimum and range of HbO2 and HHb as features. These features were found to be correlated with the effects of sevoflurane and to carry information that allows real time and automatic classification of the anesthetized state with high accuracy.

    The Veterans Health Administration (VHA) has reformed its emergency medical services. This study updates an overview of emergency medicine within VHA. This is a cross-sectional survey of VHA medical facilities offering emergency medical care. Sixty-eight percent (95/140) of facilities had emergency departments (EDs) only, 12% (16/140) had both ED and urgent care centers (UCCs), and 16% (23/140) had only UCCs. The mean (SD) ED/UCC census was 13 371 (7664). A mean (SD) of 53% (27%) of facility admissions were admitted through ED/UCCs. The median of all ED/UCC admissions admitted to intensive care unit level care was 11% (interquartile range, 7-16). Of physicians with any board certification, 16% (209/1331) of physicians had emergency medicine board certification. Emergency medical care is now available at most VHA facilities. The specialty of emergency medicine has an important but minority presence within clinical emergency medical care at VHA. Published by Elsevier Inc.

    Although an estimated 6.5 million United States (US) children aged 6-17 practiced a martial art in 2004, there have been no nationally representative studies comparing pediatric injuries among the three most popular disciplines, karate, taekwondo, and judo. Describe pediatric martial arts injuries presenting to a representative sample of US Emergency Departments (EDs) from 1990 to 2003. We reviewed all martial arts injuries captured by the US Consumer Product Safety Commission's (CPSC), National Electronic Injury Surveillance System (NEISS). An estimated 128,400 children martial arts-related injuries from 1990 to 2003. Injured tended to be male (73.0%) and had a mean age of 12.1 years. Most injuries were attributed to karate (79.5%). The most common mechanism of injury was being kicked (25.6%), followed by falling (20.6%) and kicking (18.0%). The majority of injuries occurred to the lower leg/foot/ankle (30.1%) and hand/wrist (24.5%). The most common injury diagnoses were sprains/strains (29.3%), contusions/abrasions (27.8%), and fractures (24.6%). Participants in judo sustained significantly higher proportions of shoulder/upper arm injuries than karate (IPR=4.31, 95% CI: 2.84-6.55) or taekwondo (IPR=9.75, 95% CI: 3.53-26.91) participants. There were also higher proportions of neck injuries sustained by judo participants compared to karate (IPR=4.73, 95% CI: 1.91-11.70) or taekwondo (IPR=4.17, 95% CI: 1.02-17.06) participants. Pediatric martial arts injuries differ by discipline. Understanding these injury patterns can assist with the development of discipline-specific preventive interventions.

  18. Is the World in a State of Climate Change Planetary Emergency?

    Science.gov (United States)

    Carter, Peter

    2013-04-01

    Leading climate change experts have made public statements that the world is beyond dangerous interference with the climate system, committed to a warming of 3-5°C, facing a risk of global climate catastrophe, and in a state of planetary emergency, but these conclusions are not informing climate change policy. The evidence for these statements is examined and presented in this paper. The main parameters considered are world food security and carbon feedback "runaway" or rapid global warming. 2012 was a record year for Arctic albedo loss, which amplifies Arctic warming and drives Arctic methane feedback emissions. Since 2007, atmospheric methane is experiencing a renewed, sustained increase due to feedback emissions. All potentially large positive Arctic feedbacks are operant. These include albedo loss from disappearing snow and summer sea ice; methane released from peatlands, thawing permafrost and sea floor methane hydrates; and nitrous oxide from cryoperturbed permafrost. Increasing extreme weather events have caused regional crop productivity losses on many continents since 2000. The loss of Arctic albedo might be driving extreme heat and drought in the northern hemisphere. Today the formal national pledges for emissions reductions filed with the UN, combined, commit humanity to a warming of 4.4°C (Climate Interactive) by 2100, which is more than 8°C eventually after 2100, and there are no initiatives to change this. The International Energy Agency warns that the current global economy is on track for a warming of 6°C by 2100. A simple yet novel summation approach of all unavoidable sources of warming estimates the committed unavoidable warming to be 3°C by 2100. What are the implications of these future commitments for world food security and the risk of runaway climate change? The paper considers how these commitments and the policy-relevant research findings can inform policy making with respect to an appropriate science-based mitigation response.

    This article discusses the importance of having a strong vision and culture within the context of emergency preparedness in a home-base state. It proposes a broader vision of public health, one that places public health emergency preparedness and response squarely at the center of the public health mission as a core function. It also lays out work currently underway and the future direction for maximizing the value of response-oriented partnerships at the state and local levels in the Evergreen State. The role of health care professionals and dental providers is specified in more detail. Broadening the public health vision requires recognition of the importance of multisectorial partnerships and their response potential, including the potential roles of all health-related professions and the development of systems to use that potential effectively.

    Patients in a locked-in state (LIS) due to severe neurological disorders such as amyotrophic lateral sclerosis (ALS) require seamless emergency care by their caregivers or guardians. However, it is a difficult job for the guardians to continuously monitor the patients' state, especially when direct communication is not possible. In the present study, we developed an emergency call system for such patients using a steady-state visual evoked potential (SSVEP)-based brain switch. Although there have been previous studies to implement SSVEP-based brain switch system, they have not been applied to patients in LIS, and thus their clinical value has not been validated. In this study, we verified whether the SSVEP-based brain switch system can be practically used as an emergency call system for patients in LIS. The brain switch used for our system adopted a chromatic visual stimulus, which proved to be visually less stimulating than conventional checkerboard-type stimuli but could generate SSVEP responses strong enough to be used for brain-computer interface (BCI) applications. To verify the feasibility of our emergency call system, 14 healthy participants and 3 patients with severe ALS took part in online experiments. All three ALS patients successfully called their guardians to their bedsides in about 6.56 seconds. Furthermore, additional experiments with one of these patients demonstrated that our emergency call system maintains fairly good performance even up to 4 weeks after the first experiment without renewing initial calibration data. Our results suggest that our SSVEP-based emergency call system might be successfully used in practical scenarios. © 2017 Society for Psychophysiological Research.

    Final leachates (leachate after storage or treatment processes) from 22 landfills in 12 states were analyzed for 190 pharmaceuticals and other contaminants of emerging concern (CECs), which were detected in every sample, with the number of CECs ranging from 1 to 58 (median = 22). In total, 101 different CECs were detected in leachate samples, including 43 prescription pharmaceuticals, 22 industrial chemicals, 15 household chemicals, 12 nonprescription pharmaceuticals, 5 steroid hormones, and 4 animal/plant sterols. The most frequently detected CECs were lidocaine (91%, local anesthetic), cotinine (86%, nicotine degradate), carisoprodol (82%, muscle relaxant), bisphenol A (77%, component of plastics and thermal paper), carbamazepine (77%, anticonvulsant), and N,N-diethyltoluamide (68%, insect repellent). Concentrations of CECs spanned 7 orders of magnitude, ranging from 2.0 ng/L (estrone) to 17 200 000 ng/L (bisphenol A). Concentrations of household and industrial chemicals were the greatest (∼1000-1 000 000 ng/L), followed by plant/animal sterols (∼1000-100 000 ng/L), nonprescription pharmaceuticals (∼100-10 000 ng/L), prescription pharmaceuticals (∼10-10 000 ng/L), and steroid hormones (∼10-100 ng/L). The CEC concentrations in leachate from active landfills were significantly greater than those in leachate from closed, unlined landfills (p = 0.05). The CEC concentrations were significantly greater (p < 0.01) in untreated leachate compared with treated leachate. The CEC concentrations were significantly greater in leachate disposed to wastewater treatment plants from modern lined landfills than in leachate released to groundwater from closed, unlined landfills (p = 0.04). The CEC concentrations were significantly greater (p = 0.06) in the fresh leachate (leachate before storage or treatment) reported in a previous study compared with the final leachate sampled for the present study.

    The high rate of unemployment among emerging adults (aged 18 to 25 years) is a public health concern. The risk of depression is higher among the unemployed than among the employed, but little is known about the relationship between unemployment and mental health among emerging adults. This secondary data analysis assessed the relationship between unemployment and depression among emerging adults. Data from the 2010 Behavioral Risk Factor Surveillance System (BRFSS) were analyzed. Responses to the Patient Health Questionnaire-8 provided data about the prevalence of depression. Bivariate relationships were assessed using χ(2) tests, and multivariable adjusted odds ratios were calculated with logistic regressions. Sociodemographic variables were sex, race/ethnicity, marital status, and education. In addition, logistic regression models adjusted for health insurance status, disability, smoking, and body mass index. The analyses were completed using SAS 9.3 survey procedures to account for the complex sampling design. Almost 12% of emerging adults were depressed (PHQ-8 ≥10) and about 23% were unemployed. Significantly more unemployed than employed emerging adults were classified with depression. In the final model, the odds of depression were about 3 times higher for unemployed than employed emerging adults. The relationship between unemployment and depression is significant among emerging adults. With high rates of unemployment for this age group, this population may benefit from employment- and mental-health-focused interventions.

    The 1994 Rwandan war and genocide left more than 1 million people dead; millions displaced; and the country's economic, social, and health infrastructure destroyed. Despite remaining one of the poorest countries in the world, Rwanda has made remarkable gains in health, social, and economic development over the last 20 years, but modern emergency care has been slow to progress. Rwanda has recently established the Human Resources for Health program to rapidly build capacity in multiple sectors of its healthcare delivery system, including emergency medicine. This project involves multiple medical and surgical residencies, nursing programs, allied health professional trainings, and hospital administrative support. A real strength of the program is that trainers work with international faculty at Rwanda's referral hospital, but also as emergency medicine specialty trainers when returning to their respective district hospitals. Rwanda's first emergency medicine trainees are playing a unique and important role in the implementation of emergency care systems and education in the country's district hospitals. While there has been early vital progress in building emergency medicine's foundations in Rwanda, there remains much work to be done. This will be accomplished with careful planning and strong commitment from the country's healthcare and emergency medicine leaders.

    Traumatic brain injury (TBI) has short- and long-term adverse clinical outcomes, including death and disability. TBI can be caused by a number of principal mechanisms, including motor-vehicle crashes, falls, and assaults. This report describes the estimated incidence of TBI-related emergency department (ED) visits, hospitalizations, and deaths during 2013 and makes comparisons to similar estimates from 2007. 2007 and 2013. State-based administrative health care data were used to calculate estimates of TBI-related ED visits and hospitalizations by principal mechanism of injury, age group, sex, and injury intent. Categories of injury intent included unintentional (motor-vehicle crashes, falls, being struck by or against an object, mechanism unspecified), intentional (self-harm and assault/homicide), and undetermined intent. These health records come from the Healthcare Cost and Utilization Project's National Emergency Department Sample and National Inpatient Sample. TBI-related death analyses used CDC multiple-cause-of-death public-use data files, which contain death certificate data from all 50 states and the District of Columbia. In 2013, a total of approximately 2.8 million TBI-related ED visits, hospitalizations, and deaths (TBI-EDHDs) occurred in the United States. This consisted of approximately 2.5 million TBI-related ED visits, approximately 282,000 TBI-related hospitalizations, and approximately 56,000 TBI-related deaths. TBIs were diagnosed in nearly 2.8 million (1.9%) of the approximately 149 million total injury- and noninjury-related EDHDs that occurred in the United States during 2013. Rates of TBI-EDHDs varied by age, with the highest rates observed among persons aged ≥75 years (2,232.2 per 100,000 population), 0-4 years (1,591.5), and 15-24 years (1,080.7). Overall, males had higher age-adjusted rates of TBI-EDHDs (959.0) compared with females (810.8) and the most common principal mechanisms of injury for all age groups included falls (413.2, age

    OBJECTIVE Deep brain stimulation (DBS) is an emerging treatment option for an expanding set of neurological and psychiatric diseases. Despite growing enthusiasm, the patterns and implications of this rapid adoption are largely unknown. National trends in DBS surgery performed for all indications between 2002 and 2011 are reported. METHODS Using a national database of hospital discharges, admissions for DBS for 14 indications were identified and categorized as either FDA approved, humanitarian device exempt (HDE), or emerging. Trends over time were examined, differences were analyzed by univariate analyses, and outcomes were analyzed by hierarchical regression analyses. RESULTS Between 2002 and 2011, there were an estimated 30,490 discharges following DBS for approved indications, 1647 for HDE indications, and 2014 for emerging indications. The volume for HDE and emerging indications grew at 36.1% annually in comparison with 7.0% for approved indications. DBS for emerging indications occurred at hospitals with more neurosurgeons and neurologists locally, but not necessarily at those with the highest DBS caseloads. Patients treated for HDE and emerging indications were younger with lower comorbidity scores. HDE and emerging indications were associated with greater rates of reported complications, longer lengths of stay, and greater total costs. CONCLUSIONS DBS for HDE and emerging indications underwent rapid growth in the last decade, and it is not exclusively the most experienced DBS practitioners leading the charge to treat the newest indications. Surgeons may be selecting younger and healthier patients for their early experiences. Differences in reported complication rates warrant further attention and additional costs should be anticipated as surgeons gain experience with new patient populations and targets.

    Over the past 15 years, the use of cell phones has increased 8-fold in the United States. Cell phone use has been shown to increase crash risks for drivers, but no systematic analyses have described injuries related to ambulatory cell phone use. The purpose of this study is to describe and quantitate injuries and deaths among persons using cell phones while walking. We searched the National Electronic Injury Surveillance System (NEISS) for emergency department (ED) reports of injuries related to phone use. The cases that returned were screened initially using words that would eliminate cases unlikely to be related to cell phone use and walking, possibly linked to distraction. The resulting cases were randomized and evaluated for consistency with predetermined case definitions by two authors blinded to the dates of the incidents. Cases that were disagreed upon were evaluated in a second screening by both authors for final case determination. National ED visit rates were estimated based on NEISS sampling methods. Annual variations were analyzed using linear regression with a restricted maximum likelihood approach. Our screening process identified 5,754 possible cases that occurred between 2000 and 2011, and 310 were agreed on as cases of cell-phone-induced distraction. The majority of the patients were female (68%) and 40 years of age or younger (54%). The primary mechanism of injury was a fall (72%), and most patients were treated and released from the ED (85%). No patients died from their injuries while they were in the ED. Linear modeling by year revealed a statistically significant increase in distraction injury rates over the years of study (pcell phone use has been increasing. More research is needed to determine the risks associated with walking and talking on a cell phone and to develop strategies for intervention. Cell phone use continues to increase both at home and outdoor environments. The use of smart phones, with their more enticing features, increases

    Small states are just as easily seduced by status and glory as other states. When conceived as situated in a stratified international society, small states acquire an inherent tendency to overcome their disadvantage in conventional power terms through the pursuit of status. Hence, it is precisely because of their position in the international hierarchy, not in spite of it, that strategic ideas based on state size stimulate foreign policy change in small states.

Fruits on mid-ripe and fully ripe stages were stored at three temperatures: 5.6 ± 1.57 °C and 72.8 ± 3.8% RH; 10.4 ± 0.5 °C and 95.8 ± 5.5% RH; 21.04 ± 1.63 °C and 96.9 ± 2.6% RH up to 28 storage days (SD . During storage, fruits stored at 21.04 ± 1.63 °C were evaluated every two days until 8 SD, and every four days for fruits stored at other temperatures. The harvest day was assigned as day zero. The variables evaluated were CO2 production, color of the pericarp and pulp, fresh mass loss, flesh firmness, total soluble solids, titratable acidity, contents of ascorbic acid and carotenoids. The fresh mass loss increased during storage, peaking at 5.6 °C. The reduction in ascorbic acid content was higher in fully ripe fruits at all temperatures. Mid-ripe fruits reached the end of the storage period with better quality. The temperature of 10.4 °C was the most efficient in keeping postharvest quality of peach cv.

    The functional design of a local control strategy considered suitable for bulk power system disturbed into transient emergency state was set forth in the companion paper. It utilized a particular control procedure based on an adaptively specified angle velocity threshold limit criteria. In order to consolidate the validity of the strategy, this paper describes its algorithmic implementation and discusses two extensive test results. The design philosophy and implementation of the proposed control framework are based on the hierachical control approach.

    Full Text Available In this paper, we investigate if dividend policy is influenced by ownership type. Within the dividend literature, dividends have a signaling role regarding agency costs, such that dividends may diminish insider conflicts (reduce free cash flow or may be used to extract cash from firms (tunneling effect – which could be predominant in emerging markets. We expect firms with foreign ownership and those that are listed in overseas markets to have different dividend policies and practices than those that are not, and firms with more state ownership and less individual ownership to be more likely to pay cash dividends and less likely to pay stock dividends. Using firms from an emerging economy (China, we examine whether these effects exist in corporate dividend policy and practice. We find that both foreign ownership and cross-listing have significant negative effects on cash dividends, consistent with the signaling effect and the notion of reduced tunneling activities for firms with the ability to raise capital from outside of China. Consistent with the tunneling effect, we find that firms with higher state ownership tend to pay higher cash dividends and lower stock dividends, while the opposite is true for public (individual ownership. Further analysis shows that foreign ownership mediates the effect of state ownership on dividend policy. Our results have significant implications for researchers, investors, policy makers and regulators in emerging markets.

    To investigate the epidemiology of emergency department visits for pediatric patients presenting with electrical burns to the mouth. Cross-sectional analysis of a national database. National Electronic Injury Surveillance System Database. The Consumer Product Safety Commission's National Electronic Injury Surveillance System database was used to derive a national weighted estimate of emergency department visits for oral electrical burns and was queried for each patient's age, sex, race, local of incidence, disposition, and related consumer product. There were an estimated 1042 emergency department visits for pediatric oral electrical burns from 1997 to 2012, or an average of approximately 65.1 cases per year. A total of 59.6% of patients were male. Nearly half of emergency department visits involved patients pediatric oral electrical burns varied substantially within the literature and varied from small case reports to single-year studies. Our multiyear data analysis provides evidence of decreasing annual incidence when compared with historical estimates for a common but potentially morbid injury among the pediatric population. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

    The US DOE cross-statement in the matter of proposed rulemaking in the storage and disposal of nuclear wastes is presented. It is concluded from evidence contained in the document that: (1) spent fuel can be disposed of in a manner that is safe and environmentally acceptable; (2) present plans for establishing geological repositories are an effective and reasonable means of disposal; (3) spent nuclear fuel from licensed facilities can be stored in a safe and environmentally acceptable manner on-site or off-site until disposal facilities are ready; (4) sufficient additional storage capacity for spent fuel will be established; and (5) the disposal and interim storage systems for spent nuclear fuel will be integrated into an acceptable operating system. It was recommended that the commission should promulgate a rule providing that the safety and environmental implications of spent nuclear fuel remaining on site after the anticipated expiration of the facility licenses involved need not be considered in individual facility licensing proceedings. A prompt finding of confidence in the nuclear waste disposal and storage area by the commission is also recommeded. (DMC)

    In preparation for next generation North American Land Data Assimilation System (NLDAS), 3 three advanced land surface models (CLM4.0, Noah-MP, and CLSM-F2.5) were run from 1979 4 to 2014 within the NLDAS-based framework. Monthly total water storage anomaly (TWSA) and 5 its individual water storage components were evaluated against satellite-based and in situ 6 observations, and reference reanalysis products at basin-wide and statewide scales. In general, all 7 three models are able to reasonably capture the monthly and interannual variability and 8 magnitudes for TWSA. However, contributions of the anomalies of individual water 9 components to TWSA are very dependent on the model and basin. A major contributor to the 10 TWSA is the anomaly of total column soil moisture content (SMCA) for CLM4.0 and Noah-MP 11 or groundwater storage anomaly (GWSA) for CLSM-F2.5 although other components such as 12 the anomaly of snow water equivalent (SWEA) also play some role. For each individual water 13 storage component, the models are able to capture broad features such as monthly and 14 interannual variability. However, there are large inter-model differences and quantitative 15 uncertainties in this study. Therefore, it should be thought of as a preliminary synthesis and 16 analysis.

    Full Text Available To reduce hydrological uncertainties in the regular monitoring of poorly gauged lakes and reservoirs, multi-dimensional remote sensing data have emerged as an excellent alternative. In this paper, we propose three methods to delineate the volume of such equipotential water bodies through a combination of altimetry (1D, Landsat (2D and bathymetry (2D data, namely an altimetry-bathymetry-volume method (ABV, a Landsat-bathymetry-volume method (LBV and an altimetry-Landsat-volume-variation method (ALVV. The first two data products are further merged by a Kalman-filter-based state space model (SSM to obtain a combined estimate (CSSME time series and near future prediction. To validate our methods, we tested them on the well-measured Lake Mead and further applied them on the poorly gauged Aral Sea, which has inaccurate bathymetry and very limited ground observation data. We updated the lake bathymetry of the Aral Sea, which was more than half a century old. The resultant remote sensing products have a very good long-term agreement among each other. The Lake Mead volume estimations are very highly coherent with the ground observations for all cases (R2 > 0.96 and NRMSE < 2.1%, except for the forecast (R2 = 0.75 and NRMSE = 3.7%. Due to lack of in situ data for the Aral Sea, the estimated volumes are compared, and the entire Aral Sea LBV and ABV have R2 = 0.91 and NRMSE = 5.5%, and the forecast compared to CSSME has R2 = 0.60 and NRMSE = 2.4%.

    2016-02-01

    To describe the compliance of urgent care centers in the United States with pediatric care recommendations for emergency preparedness as set forth by the American Academy of Pediatrics. An electronic questionnaire was distributed to urgent care center administrators as identified by the American Academy of Urgent Care Medicine directory. A total of 122 questionnaires of the 872 distributed were available for analysis (14% usable response rate). The most common diagnoses reported for pediatric patients included otitis media (72%), upper respiratory illness (69%), strep pharyngitis (61%), bronchiolitis (30%), and extremity sprain/strain (28%). Seventy-one percent of centers have contacted community emergency medical services (EMS) to transport a critically ill or injured child to their local emergency department in the past year. Sixty-two percent of centers reported having an established written protocol with community EMS and 54% with their local emergency department or hospital. Centers reported the availability of the following essential medications and equipment: oxygen source (75%), nebulized/inhaled β-agonist (95%), intravenous epinephrine (88%), oxygen masks/nasal cannula (89%), bag-valve-mask resuscitator (81%), suctioning device (60%), and automated external defibrillator (80%). Centers reported the presence of the following written emergency plans: respiratory distress (40%), seizures (67%), dehydration/shock (69%), head injury (59%), neck injury (67%), significant fracture (69%), and blunt chest or abdominal injury (81%). Forty-seven percent of centers conduct formal reviews of emergent or difficult cases in a quality improvement format. Areas for improvement in urgent care center preparedness were identified, such as increasing the availability of essential medications and equipment, establishing transfer and transport agreements with local hospitals and community EMS, and ensuring a structured quality improvement program.

    2011-12-01

    This poster will present an overview of successes and challenges observed by the authors during this major tsunami response event. The Tohoku, Japan tsunami was the most costly to affect California since the 1964 Alaskan earthquake and ensuing tsunami. The Tohoku tsunami caused at least $50 million in damage to public facilities in harbors and marinas along the coast of California, and resulted in one fatality. It was generated by a magnitude 9.0 earthquake which occurred at 9:46PM PST on Thursday, March 10, 2011 in the sea off northern Japan. The tsunami was recorded at tide gages monitored by the West Coast/Alaska Tsunami Warning Center (WCATWC), which projected tsunami surges would reach California in approximately 10 hours. At 12:51AM on March 11, 2011, based on forecasted tsunami amplitudes, the WCATWC placed the California coast north of Point Conception (Santa Barbara County) in a Tsunami Warning, and the coast south of Point Conception to the Mexican border in a Tsunami Advisory. The California Emergency Management Agency (CalEMA) activated two Regional Emergency Operation Centers (REOCs) and the State Operation Center (SOC). The California Geological Survey (CGS) deployed a field team which collected data before, during and after the event through an information clearinghouse. Conference calls were conducted hourly between the WCATWC and State Warning Center, as well as with emergency managers in the 20 coastal counties. Coordination focused on local response measures, public information messaging, assistance needs, evacuations, emergency shelters, damage, and recovery issues. In the early morning hours, some communities in low lying areas recommended evacuation for their citizens, and the fishing fleet at Crescent City evacuated to sea. The greatest damage occurred in the harbors of Crescent City and Santa Cruz. As with any emergency, there were lessons learned and important successes in managing this event. Forecasts by the WCATWC were highly accurate

    Chest pain is a common complaint in the emergency department often necessitating testing to exclude underlying obstructive coronary artery disease. While the traditional evaluation of patients with suspected acute coronary syndrome often consists of serial electrocardiograms and cardiac biomarkers, followed by selective use of stress testing for further risk stratification, this approach is costly and inefficient. Recently, coronary computed tomographic angiography (CTA) has offered an alternative approach with a high sensitivity and negative predictive value to exclude obstructive coronary artery disease that can rapidly identify patients with low rates of downstream major adverse cardiac events. In this review, the authors provide an overview of available data on the use of CTA for evaluating acute chest pain, while emphasizing its advantages and disadvantages compared to existing strategies. In addition, we provide a suggested algorithm to identify how CTA can be incorporated into the evaluation of acute chest pain and discuss tips for successful implementation of CTA in the emergency department.

  8. Harm reduction or women's rights? Debating access to emergency contraceptive pills in Canada and the United States.

    2007-12-01

    This article compares the ethical pivot points in debates over nonprescription access to emergency contraceptive pills in Canada and the United States. These include women's right to be informed about the contraceptive method and its mechanism of action, pharmacists' conscientious objection concerning the dispensing of emergency contraceptive pills, and rights and equality of access to the method, especially for poor women and minorities. In both countries, arguments in support of expanding access to the pills were shaped by two competing orientations toward health and sexuality. The first, "harm reduction," promotes emergency contraception as attenuating the public health risks entailed in sex. The second orientation regards access to pills as a question of women's right to engage in nonprocreative sex and to choose from among all reproductive health-care options. The authors contend that arguments for expanding access to emergency contraceptive pills that frame issues in terms of health and science are insufficient bases for drug regulation; ultimately, women's health is also a matter of women's rights.

    Leggio, William Joseph

    2014-10-01

    This study investigated how leadership is learned in Emergency Medical Services (EMS) from a multi-national perspective by interviewing EMS providers from multiple nations working in Riyadh, Kingdom of Saudi Arabia. A phenomenological, qualitative methodology was developed and 19 EMS providers from multiple nations were interviewed in June 2013. Interview questions focused on how participants learned EMS leadership as an EMS student and throughout their careers as providers. Data were analyzed to identify themes, patterns, and codes to be used for final analysis to describe findings. Emergency Medical Services leadership is primarily learned from informal mentoring and on-the-job training in less than supportive environments. Participants described learning EMS leadership during their EMS education. A triangulation of EMS educational resources yielded limited results beyond being a leader of patient care. The only course that yielded results from triangulation was EMS Management. The need to develop EMS leadership courses was supported by the findings. Findings also supported the need to include leadership education as part of continuing medical education and training. Emergency Medical Services leadership education that prepares students for the complexities of the profession is needed. Likewise, the need for EMS leadership education and training to be part of continuing education is supported. Both are viewed as a way to advance the EMS profession. A need for further research on the topic of EMS leadership is recognized, and supported, with a call for action on suggested topics identified within the study.

  12. The state-of-the-art of emergency contraception with the cutting edge drug

    Sarkar, Narendra Nath

    2011-01-01

    Full Text Available The objective of this study is to evaluate and elucidated the potential of selective progesterone receptor modulators (SPRMs to be an effective emergency contraception (EC. The data are extracted from the literature through the MEDLINE database service from 2000–2010. The SPRMs are in fact progesterone receptor ligands that could bind to progesterone receptor (PR and exert antagonistic, agonistic or mixed agonist-antagonistic effects. These SPRMs are mifepristone, onapristone, asoprisnil, ulipristal, proellex among other compounds. Currently developed SPRMs may exert contraceptive effects by inhibiting ovulation and retarding endometrial synchronization. Low-doses of progesterone antagonists retard endometrial maturation without affecting ovulation. Mifepristone being a SPRM is effective for prevention of pregnancy but with prostaglandin acts as an excellent abortifacient; yet could not compete with levonorgestrel as EC. However, a single dose of 30 mg ulipristal acetate, another SPRM with similar effectiveness and side effect profiles as 1.5 mg levonorgestrel EC, has shown wider ‘window of effect’ by inhibition of the LH peak even if administered at the advanced pre-ovulatory phase, a time when use of levonorgestrel EC is no longer effective. Thus, ulipristal acetate goes one-step ahead of levonorgestrel in the field of emergency contraception treatment. Further studies are needed to explore the potential of other SPRMs to be cutting edge emergency contraceptive drugs.

    Flexible behaviors are organized by complex neural networks in the prefrontal cortex. Recent studies have suggested that such networks exhibit multiple dynamical states, and can switch rapidly from one state to another. In many complex systems such as the brain, the early-warning signals that may predict whether a critical threshold for state transitions is approaching are extremely difficult to detect. We hypothesized that increases in firing irregularity are a crucial measure for predicting state transitions in the underlying neuronal circuits of the prefrontal cortex. We used both experimental and theoretical approaches to test this hypothesis. Experimentally, we analyzed activities of neurons in the prefrontal cortex while monkeys performed a maze task that required them to perform actions to reach a goal. We observed increased firing irregularity before the activity changed to encode goal-to-action information. Theoretically, we constructed theoretical generic neural networks and demonstrated that changes in neuronal gain on functional connectivity resulted in a loss of stability and an altered state of the networks, accompanied by increased firing irregularity. These results suggest that assessing the temporal pattern of neuronal fluctuations provides important clues regarding the state stability of the prefrontal network. We also introduce a novel scheme that the prefrontal cortex functions in a metastable state near the critical point of bifurcation. According to this scheme, firing irregularity in the prefrontal cortex indicates that the system is about to change its state and the flow of information in a flexible manner, which is essential for executive functions. This metastable and/or critical dynamical state of the prefrontal cortex may account for distractibility and loss of flexibility in the prefrontal cortex in major mental illnesses such as schizophrenia.

    Full Text Available Developing aquifers as underground water supply reservoirs is an advantageous approach applicable to meeting water management objectives. Aquifer storage and recovery (ASR is a direct injection and subsequent withdrawal technology that is used to increase water supply storage through injection wells. Due to site-specific hydrogeological quantification and evaluation to assess ASR suitability, limited methods have been developed to identify suitability on regional scales that are also applicable at local scales. This paper presents an ASR site scoring system developed to qualitatively assess regional and local suitability of ASR using 9 scored metrics to determine total percent of ASR suitability, partitioned into hydrogeologic properties, operational considerations, and regulatory influences. The development and application of a qualitative water well suitability method was used to assess the potential groundwater response to injection, estimate suitability based on predesignated injection rates, and provide cumulative approximation of statewide and local storage prospects. The two methods allowed for rapid assessment of ASR suitability and its applicability to regional and local water management objectives at over 280 locations within 62 watersheds in Washington, USA. It was determined that over 50% of locations evaluated are suitable for ASR and statewide injection potential equaled 6400 million liters per day. The results also indicate current limitations and/or potential benefits of developing ASR systems at the local level with the intent of assisting local water managers in strategic water supply planning.

    The rational design of improved electrode–electrolyte interfaces (EEI) for energy storage is critically dependent on a molecular-level understanding of ionic interactions and nanoscale phenomena. The presence of non-redox active species at EEI has been shown to strongly influence Faradaic efficiency and long-term operational stability during energy storage processes. Herein, we achieve substantially higher performance and long-term stability of EEI prepared with highly dispersed discrete redox-active cluster anions (50 ng of pure ∼0.75 nm size molybdenum polyoxometalate (POM) anions on 25 μg (∼0.2 wt%) carbon nanotube (CNT) electrodes) by complete elimination of strongly coordinating non-redox species through ion soft landing (SL). Electron microscopy provides atomically resolved images of a uniform distribution of individual POM species soft landed directly on complex technologically relevant CNT electrodes. In this context, SL is established as a versatile approach for the controlled design of novel surfaces for both fundamental and applied research in energy storage. PMID:27097686

Medicaid beneficiaries incurred +21.1% and +25.1% higher odds for major or minor amputations, respectively, than Medicare patients (p<0.05). Persons within the lowest income quartile regions were associated with a +38.5% higher odds of major amputation (p<0.05) versus the highest income regions. Diabetic foot complications exact a substantial clinical and economic toll in acute care settings, particularly among the rural and working poor. Clear opportunities exist to reduce costs and improve outcomes for this systematically-neglected condition by establishing effective practice paradigms

    Emergency general surgery (EGS) is a major component of acute care surgery, however, limited data exist on mortality with respect to trauma center (TC) designation. We hypothesized that mortality would be lower for EGS patients treated at a TC vs non-TC (NTC). A retrospective review of the Maryland Health Services Cost Review Commission database from 2009 to 2013 was performed. The American Association for the Surgery of Trauma EGS ICD-9 codes were used to identify EGS patients. Data collected included demographics, TC designation, emergency department admissions, and All Patients Refined Severity of Illness (APR_SOI). Trauma center designation was used as a marker of a formal acute care surgery program. Primary outcomes included in-hospital mortality. Multivariable logistic regression analysis was performed controlling for age. There were 817,942 EGS encounters. Mean ± SD age of patients was 60.1 ± 18.7 years, 46.5% were males; 71.1% of encounters were at NTCs; and 75.8% were emergency department admissions. Overall mortality was 4.05%. Mortality was calculated based on TC designation controlling for age across APR_SOI strata. Multivariable logistic regression analysis did not show statistically significant differences in mortality between hospital levels for minor APR_SOI. For moderate APR_SOI, mortality was significantly lower for TCs compared with NTCs (p surgery patients treated at TCs had lower mortality for moderate APR_SOI, but increased mortality for extreme APR_SOI when compared with NTCs. Additional investigation is required to better evaluate this unexpected finding. Copyright © 2015 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

Methods: A literature review was conducted using Medline, Embase, and Current Contents databases, up to September 1, 2013 to identify publications reporting new contraceptives in development using combinations of the search terms: contraception, contraceptives, oral contraceptives, patch, vaginal ring, implants, intrauterine contraceptives, and emergency contraception (EC. Also, several experts in the field were also consulted to document ongoing projects on contraception development. Additionally, the Clinicaltrial.gov website was searched for ongoing studies on existing contraceptive methods and new and emerging female contraceptives developed over the past 5 years. Information was also obtained from the pharmaceutical industry. Results: Early sexual debut and late menopause means that women may require contraception for up to 30 years. Although oral, injectable, vaginal, transdermal, subdermal, and intrauterine contraceptives are already available, new contraceptives have been developed in an attempt to reduce side effects and avoid early discontinuation, and to fulfill women's different requirements. Research efforts are focused on replacing ethinyl-estradiol with natural estradiol to reduce thrombotic events. In addition, new, less androgenic progestins are being introduced and selective progesterone receptor

Our calculations based on the proposed model reproduce the experimental time-evolution of pressure and temperature with a single set of fitting parameters for hydrogen and deuterium injection. The model we generated with a highly generalized set of formulations can be applied for any combination of a gas species and a catalytic adsorbent/absorbent. Our model can be used as a basis for future research into hydrogen storage and solid-state nuclear fusion technologies.

    2013-11-01

    Sudden cardiac death (SCD) events are tragic. Secondary prevention of SCD depends on availability of automated external defibrillators (AEDs). High school athletes represent a high-risk group for SCD, and current efforts aim to place AEDs in all high schools. The prevalence of AEDs and emergency planning for sudden cardiac arrest (SCA) in Vermont high schools is similar to other states. Understanding specific needs and limitations in rural states may prevent SCD in rural high schools. Cross-sectional survey. A survey was distributed to all 74 Vermont high school athletic directors. Outcome measures included AED prevalence, AED location, individuals trained in cardiopulmonary resuscitation (CPR) and AED utilization, funding methods for AED attainment, and the establishment of an emergency action plan (EAP) for response to SCA. All schools (100%, 74 of 74) completed the survey. Of those, 60 (81%) schools have at least 1 AED on school premises, with the most common location for AED placement being the main office or lobby (50%). Larger sized schools were more likely to have an AED on the premises than smaller sized schools (P = 0.00). School nurses (77%) were the most likely individuals to receive formal AED training. Forty-one schools (55%) had an EAP in place for response to SCA, and 71% of schools coordinated AED placement with local emergency medical services (EMS) responders. In Vermont, more than two-thirds of high schools have at least 1 AED on school premises. However, significant improvement in the establishment of EAPs for SCA and training in CPR and AED utilization is essential given the rural demography of the state of Vermont. Rural high schools inherently have longer EMS response times. In addition to obtaining AEDs, high schools must develop a public access to defibrillation program to maximize the chance of survival following cardiac arrest, especially in rural settings.

    Hypertension is a common chronic condition, but the burden of emergency department (ED) visits due to hypertension and associated patient and hospital characteristics are not well described. The goals of this study were to (1) establish the burden of hypertension-related ED visits, estimated by the total number, proportion of adult visits, and population-based rate, (2) evaluate for change over time, and (3) identify associated patient and hospital characteristics. The Nationwide Emergency Department Sample from 2006 to 2012 was used to identify hypertension-related ED visits (International Classification of Diseases, Ninth Revision, Clinical Modification codes 401 to 405, inclusive, and 437.2), and this was linked to US Census Bureau July population estimates to determine population-based rates for each study year. Negative binomial regression was performed to determine whether rates of hypertension-related ED visits changed over time. A total of 165,946,807 hypertension-related ED visits occurred during the 7-year study period (23.6% of all adult ED visits), and hypertension was the primary diagnosis for 6,399,088 (0.9% of all adult ED visits). The estimated yearly incidence rate increased 5.2% per year (incident rate ratio, 1.052; 95% confidence interval, 1.044 to 1.061; p safety net hospitals and among uninsured patients. In conclusion, these data indicate that hypertension-related ED visits are common and increasing. Published by Elsevier Inc.

    Background To examine temporal trends in emergency departments (ED) visits for bronchiolitis among US children between 2006 and 2010. Methods Serial, cross-sectional analysis of the Nationwide Emergency Department Sample, a nationally-representative sample of ED patients. We used ICD-9-CM code 466.1 to identify children bronchiolitis. Primary outcome measures were rate of bronchiolitis ED visits, hospital admission rate, and ED charges. Results Between 2006 and 2010, weighted national discharge data included 1,435,110 ED visits with bronchiolitis. There was a modest increase in the rate of bronchiolitis ED visits, from 35.6 to 36.3 per 1000 person-years (2% increase; Ptrend=0.008), due to increases in the ED visit rate among children from 12 months to 23 months (24% increase; Ptrendinfants (4% decrease; Ptrendbronchiolitis increased from $337 million to $389 million (16% increase; Ptrendbronchiolitis ED visits by age group. Despite a significant increase in associated ED charges, ED-associated hospital admission rates for bronchiolitis significantly decreased over this same period. PMID:23934206

    Full Text Available The interaction of electrons with a periodic potential of atoms in crystalline solids gives rise to band structure. The band structure of existing materials can be measured by photoemission spectroscopy and accurately understood in terms of the tight-binding model, however not many experimental approaches exist that allow to tailor artificial crystal lattices using a bottom-up approach. The ability to engineer and study atomically crafted designer materials by scanning tunnelling microscopy and spectroscopy (STM/STS helps to understand the emergence of material properties. Here, we use atom manipulation of individual vacancies in a chlorine monolayer on Cu(100 to construct one- and two-dimensional structures of various densities and sizes. Local STS measurements reveal the emergence of quasiparticle bands, evidenced by standing Bloch waves, with tuneable dispersion. The experimental data are understood in terms of a tight-binding model combined with an additional broadening term that allows an estimation of the coupling to the underlying substrate.

    This case-series describes the 6 human infections with Onchocerca lupi, a parasite known to infect cats and dogs, that have been identified in the United States since 2013. Unlike cases reported outside the country, the American patients have not had subconjunctival nodules but have manifested more invasive disease (eg, spinal, orbital, and subdermal nodules). Diagnosis remains challenging in the absence of a serologic test. Treatment should be guided by what is done for Onchocerca volvulus as there are no data for O. lupi. Available evidence suggests that there may be transmission in southwestern United States, but the risk of transmission to humans is not known. Research is needed to better define the burden of disease in the United States and develop appropriately-targeted prevention strategies.

    Full Text Available City Managers came into being in the early 1900.s because of the corruption, waste, and lack of responsiveness of local governments in the United States. Business leaders in large cities had begun to recognise that major changes in their local governments were desperately needed for their businesses to grow and prosper. Andrew Carnegie, a founder of United States Steel, had indicated that business needed a stable society to prosper. Local government had to become responsive to the changing needs of the poor, abused and neglected children, the mentally ill and the elderly, to cite a few examples.

  14. Is the World in a State of Committed Global Climate Change Planetary Emergency?

    Science.gov (United States)

    Carter, P.

    2013-12-01

    The evidence for a planetary climate change emergency (as defined by the WHO) is examined and presented in this paper. The main parameters considered are multiple adverse impacts on world food security as well as multiple positive amplifying Arctic feedbacks. The overriding reason for considering a planetary emergency is global climate change commitment - at today's warming of 0.8C we are committed (locked in) to about double today's warming in the future from the ocean heat lag alone (NRC 2010). Total unavoidable warming commitment is far more than double today's warming. Using a novel policy-relevant yet simple summation approach of all unavoidable sources of warming, it is estimated that, without a drastic emergency response, committed unavoidable warming due to climate system inertias is more than 3C by 2100, which could occur by 2050. Risk is much higher and can be accommodated by taking plausible worst-case results. 2012 was a record year for Arctic albedo loss, which amplifies Arctic warming and drives Arctic methane feedback emissions. All sources of Arctic albedo are on a rapid trend of decline. Since 2007, atmospheric methane is on a renewed, sustained increase - due to planetary feedback source emissions. All potentially large, positive (amplifying), Arctic feedbacks are operant. These include albedo loss from disappearing snow and summer sea ice, more methane released from peat rich wetlands, thawing permafrost and sub seafloor methane pools, and also carbon dioxide and nitrous oxide from thawing permafrost. Recent research finds permafrost is found to hold far more carbon and to be far more sensitive to warming than previously estimated. According to Russian researchers, subsea methane hydrate presents a planetary catastrophic risk. Increasing episodic extreme weather events have caused regional crop productivity losses on many continents (notably in the Northern Hemisphere since 2000), which have been linked to global warming.

  15. The emergence of sociology from political economy in the United States: 1890 to 1940.

    2009-01-01

    Professional sociology in the U.S. began as a field area within economics, but gradually emerged as a separate discipline. Using new data on joint meetings and the separation of departments, I track interdisciplinary relations through three phases: sponsorship (1890-1905), collaboration (1905-1940), and disengagement (post-1940). In the early years, sociology was mostly a branch of economics departments. With the formation of the American Sociological Society, relations with economics began to be more characterized by professionally autonomous collaboration. The 1920s saw a large wave of sociology departments separating from economics. Still, joint annual meetings (including joint presidential addresses) remained the norm until 1940. Paradigmatic conflict between institutional and neoclassical economists was the major force that sustained the economics-sociology collaboration. As institutionalism faded from the scene in the late 1930s, so went interdisciplinary contact.

    Emergency general surgery (EGS) admissions account for more than three million hospitalizations in the US annually; and interhospital transfers (IHTs) are costly. We aimed to better understand the population of transferred EGS patients and their subsequent care in a nationally representative sample. Using the 2002-2011 Nationwide Inpatient Sample, we identified patients aged ≥18 years with an EGS noncardiovascular principal diagnosis who were transferred from another hospital with urgent or emergent admission status. Patient demographics, hospitalization characteristics, rates of operation, and mortality were identified. Procedure codes were classified into surgery and procedures based on the HCUP Surgery Flag. We identified an estimated 525,913 EGS admissions transferred from another acute care hospital. The mean age was 60 years, 51% were female, and >50% were Medicare patients. The rate of EGS IHTs increased while mortality decreased. Surgery was required for only 33% of transferred patients. The most common surgeries were laparoscopic cholecystectomy, lysis of adhesions, and wound debridement. The median length of stay was 4.4 days, 92% of patients were cared for in urban hospitals, and >50% in teaching hospitals. The percent of patients with an EGS diagnosis requiring IHT is increasing, which may reflect a trend toward regionalization of EGS. Transfers require significant resources and may delay care. More than half of the EGS patients did not require surgical intervention. Future studies to identify populations who benefit from IHT and ideal timing of transfer can establish opportunities for optimizing resource utilization and patient outcomes.

    The discipline of emergency medicine (EM) has rapidly changed over the past 10 years, resulting in greater involvement of the specialty in undergraduate medical education. The authors sought to present a review of how, when, and where EM is currently taught in U.S. medical schools and to include general program characteristics, such as number of required clerkships, clinical expectations and experiences, use of the national curriculum guide, didactic content, and methods of assessment and grading. The authors surveyed representatives of the 128 U.S. allopathic medical schools on medical education in 2010. Contacts were drawn from established databases, direct inquiries, and medical school websites. Up to five attempts were made to contact representatives through e-mail and telephone. Descriptive statistics were used to summarize the data. The survey response rate was 83.6%. Fifty-two percent of medical schools now require students to complete EM clerkships. Required EM clerkships usually last 4 weeks and take place during the fourth year of medical school. They require students to complete a mean (±SD) of 14.3 (±2.8) shifts, which average 8.9 (±1.4) hours in length. Programs include a mean (±SD) of 18 (±10.4) hours of didactics. Approximately 60% of respondents report that both residents and attending physicians precept students. Assessments of students primarily include written clinical performance assessments and end-of-rotation written tests. These assessments contribute 66.8 and 24.5%, respectively, to the clerkship grade. Currently more than half of all U.S. medical schools require EM clerkships in their undergraduate medical curricula. This article reports an overview of EM programs at the undergraduate level. © 2013 by the Society for Academic Emergency Medicine.

  18. Emergence of a super-synchronized mobbing state in a large population of coupled chemical oscillators

    Oscillatory phenomena are ubiquitous in Nature. The ability of a large population of coupled oscillators to synchronize constitutes an important mechanism to express information and establish communication among members. To understand such phenomena, models and experimental realizations of globally coupled oscillators have proven to be invaluable in settings as varied as chemical, biological and physical systems. A variety of rich dynamical behavior has been uncovered, although usually in the context of a single state of synchronization or lack thereof. Through the experimental and numerical study of a large population of discrete chemical oscillators, here we report on the unexpected discovery of a new phenomenon revealing the existence of dynamically distinct synchronized states reflecting different degrees of communication. Specifically, we discover a novel large-amplitude super-synchronized state separated from the conventionally reported synchronized and quiescent states through an unusual sharp jump transition when sampling the strong coupling limit. Our results assume significance for further elucidating globally coherent phenomena, such as in neuropathologies, bacterial cell colonies, social systems and semiconductor lasers.

  2. Whole genome sequencing to investigate the emergence of clonal complex 23 Neisseria meningitidis serogroup Y disease in the United States.

    Directory of Open Access Journals (Sweden)

    Mary G Krauland

    Full Text Available In the United States, serogroup Y, ST-23 clonal complex Neisseria meningitidis was responsible for an increase in meningococcal disease incidence during the 1990s. This increase was accompanied by antigenic shift of three outer membrane proteins, with a decrease in the population that predominated in the early 1990s as a different population emerged later in that decade. To understand factors that may have been responsible for the emergence of serogroup Y disease, we used whole genome pyrosequencing to investigate genetic differences between isolates from early and late N. meningitidis populations, obtained from meningococcal disease cases in Maryland in the 1990s. The genomes of isolates from the early and late populations were highly similar, with 1231 of 1776 shared genes exhibiting 100% amino acid identity and an average π(N  =  0.0033 and average π(S  =  0.0216. However, differences were found in predicted proteins that affect pilin structure and antigen profile and in predicted proteins involved in iron acquisition and uptake. The observed changes are consistent with acquisition of new alleles through horizontal gene transfer. Changes in antigen profile due to the genetic differences found in this study likely allowed the late population to emerge due to escape from population immunity. These findings may predict which antigenic factors are important in the cyclic epidemiology of meningococcal disease.

  3. Are physicians likely to adopt emerging mobile technologies? Attitudes and innovation factors affecting smartphone use in the Southeastern United States.

    2012-01-01

    The smartphone has emerged as an important technological device to assist physicians with medical decision making, clinical tasks, and other computing functions. A smartphone is a device that combines mobile telecommunication with Internet accessibility as well as word processing. Moreover, smartphones have additional features such as applications pertinent to clinical medicine and practice management. The purpose of this study was to investigate the innovation factors that affect a physician's decision to adopt an emerging mobile technological device such as a smartphone. The study sample consisted of 103 physicians from community hospitals and academic medical centers in the southeastern United States. Innovation factors are elements that affect an individual's attitude toward using and adopting an emerging technology. In our model, the innovation characteristics of compatibility, job relevance, the internal environment, observability, personal experience, and the external environment were all significant predictors of attitude toward using a smartphone. These influential innovation factors presumably are salient predictors of a physician's attitude toward using a smartphone to assist with clinical tasks. Health information technology devices such as smartphones offer promise as a means to improve clinical efficiency, medical quality, and care coordination and possibly reduce healthcare costs.

  4. Emergence of equilibrium thermodynamic properties in quantum pure states. I. Theory.

    2010-07-21

    Investigation on foundational aspects of quantum statistical mechanics recently entered a renaissance period due to novel intuitions from quantum information theory and to increasing attention on the dynamical aspects of single quantum systems. In the present contribution a simple but effective theoretical framework is introduced to clarify the connections between a purely mechanical description and the thermodynamic characterization of the equilibrium state of an isolated quantum system. A salient feature of our approach is the very transparent distinction between the statistical aspects and the dynamical aspects in the description of isolated quantum systems. Like in the classical statistical mechanics, the equilibrium distribution of any property is identified on the basis of the time evolution of the considered system. As a consequence equilibrium properties of quantum system appear to depend on the details of the initial state due to the abundance of constants of the motion in the Schrodinger dynamics. On the other hand the study of the probability distributions of some functions, such as the entropy or the equilibrium state of a subsystem, in statistical ensembles of pure states reveals the crucial role of typicality as the bridge between macroscopic thermodynamics and microscopic quantum dynamics. We shall consider two particular ensembles: the random pure state ensemble and the fixed expectation energy ensemble. The relation between the introduced ensembles, the properties of a given isolated system, and the standard quantum statistical description are discussed throughout the presentation. Finally we point out the conditions which should be satisfied by an ensemble in order to get meaningful thermodynamical characterization of an isolated quantum system.

    Full Text Available In the likely event that immigration reform will be discussed again in the U.S. Congress in the year 2010, the circumstances and events that have led to the current state of affairs will here be analysed: firstly, the immigration policies implemented from 9/11 until the failed attempt at reforming immigration legislation; secondly, the complex array of recent local and state initiatives which have increasingly served as a substitute for federal immigration control and management. As I examine this evolution and the conflict it has generated, I will devote special attention to undocumented immigrants: from the harsh treatment to which they were subjected during the Bush presidency to the conditions in which they have come to mobilize and have emerged as political actors, even to the point of transforming ideas of citizenship and related rights.

    This paper addresses joint wind-wave induced dynamic responses of a semi-type offshore floating wind turbine (OFWT) under normal states and fault event conditions. The analysis in this paper is conducted in time domain, using an aero-hydro-servo-elastic simulation code-FAST. Owing to the unique viscous features of the reference system, the original viscous damping model implemented in FAST is replaced with a quadratic one to gain an accurate capture of viscous effects. Simulation cases involve free-decay motion in still water, steady motions in the presence of regular waves and wind as well as dynamic response in operational sea states with and without wind. Simulations also include the cases for transient responses induced by fast blade pitching after emergency shutdown. The features of platform motions, local structural loads and a typical mooring line tension force under a variety of excitations are obtained and investigated.

    In 2008, the Institute of Medicine released a letter report identifying 4 research priority areas for public health emergency preparedness in public health system research: (1) enhancing the usefulness of training, (2) improving timely emergency communications, (3) creating and maintaining sustainable response systems, and (4) generating effectiveness criteria and metrics. To (1) identify and characterize public health system research in public health emergency preparedness produced in the United States from 2009 to 2015, (2) synthesize research findings and assess the level of confidence in these findings, and (3) describe the evolution of knowledge production in public health emergency preparedness system research. Search Methods and Selection Criteria. We reviewed and included the titles and abstracts of 1584 articles derived from MEDLINE, EMBASE, and gray literature databases that focused on the organizational or financial aspects of public health emergency preparedness activities and were grounded on empirical studies. We included 156 articles. We appraised the quality of the studies according to the study design. We identified themes during article analysis and summarized overall findings by theme. We determined level of confidence in the findings with the GRADE-CERQual tool. Thirty-one studies provided evidence on how to enhance the usefulness of training. Results demonstrated the utility of drills and exercises to enhance decision-making capabilities and coordination across organizations, the benefit of cross-sector partnerships for successfully implementing training activities, and the value of integrating evaluation methods to support training improvement efforts. Thirty-six studies provided evidence on how to improve timely communications. Results supported the use of communication strategies that address differences in access to information, knowledge, attitudes, and practices across segments of the population as well as evidence on specific

    Radiation regulatory authorities have a responsibility for the management of radioactive waste. This, more often than not, includes the collection and safe storage of radioactive sources in disused radiation devices and devices seized by the regulatory authority following an accident, abandonment or unauthorised use. The public aversion to all things radioactive, regardless of the safety controls, together with the Not In My Back Yard (NIMBY) syndrome combine to make the establishment of a radioactive materials store a near impossible task, despite the fact that such a facility is a fundamental tool for regulatory authorities to provide for the radiation safety of the public. In Queensland the successful completion and operational use of such a storage facility has taken a total of 8 years of concerted effort by the staff of the regulatory authority, the expenditure of over $2 million (AUS) not including regulatory staff costs and the cost of construction of an earlier separate facility. This paper is a summary of the major developments in the planning, construction and eventual operation of the facility including technical and administrative details, together with the lessons learned from the perspective of the overall project.

    Full Text Available Introduction: Traumatic brain injury (TBI can be complicated among older adults due to age-related frailty, a greater prevalence of chronic conditions and the use of anticoagulants. We conducted this study using the latest available, nationally-representative emergency department (ED data to characterize visits for TBI among older adults.Methods: We used the 2006-2008 National Hospital Ambulatory Medical Care – Emergency Department (NHAMCS-ED data to examine ED visits for TBI among older adults. Population-level estimates of triage immediacy, receipt of a head computed tomography (CT and/or head magnetic resonance imaging (MRI, and hospital admission by type were used to characterize 1,561 sample visits, stratified by age <65 and ≥65 years of age.Results: Of ED visits made by persons ≥65 years of age, 29.1% required attention from a physician within 15 minutes of arrival; 82.1% required a head CT, and 20.9% required hospitalization. Persons≥65 years of age were 3 times more likely to receive a head CT or MRI compared to younger patients presenting with TBI (adjusted odds ratio [aOR] 3.2; 95% confidence interval [CI], 1.8-5.8, and were 4 times more likely to be admitted to an intensive care unit, step-down unit, or surgery (aOR 4.1; 95% CI 2.1-8.0 compared to younger patients presenting with TBI, while controlling for sex and race.Conclusion: Results demonstrate increased emergent service delivery for older persons presenting with TBI.

    Full Text Available Post-coma persons in a minimally conscious state (MCS or emerged/emerging from such state (E-MCS, who are affected by extensive motor impairment and lack of speech, may develop an active role and interact with their environment with the help of technology-aided intervention programs. Although a number of studies have been conducted in this area during the last few years, new evidence about the efficacy of those programs is warranted. These three studies were an effort in that direction. Study I assessed a technology-aided program to enable six MCS participants to access preferred environmental stimulation independently. Studies II and III assessed technology-aided programs to enable six E-MCS participants to make choices. In Study II, three of those participants were led to choose among leisure and social stimuli, and caregiver interventions automatically presented to them. In Study III, the remaining three participants were led to choose (a among general stimulus/intervention options (e.g., songs, video-recordings of family members, and caregiver interventions and then (b among variants of those options. The results of all three studies were largely positive with substantial increases of independent stimulation access for the participants of Study I and independent choice behavior for the participants of Studies II and III. The results were analyzed in relation to previous data and in terms of their implications for daily contexts working with MCS and E-MCS persons affected by multiple disabilities.

    Dance is a popular activity associated with many physical and mental health benefits, but injuries are a concern for all skill levels. Previous studies have focused on professional dancers or particular genres, meaning the population-wide characteristics of injuries is unknown. This study's objective was to identify the incidence and types of dance-related injuries evaluated in emergency departments in the United States over the 14-year period 2000-2013. Data were obtained from the nationally representative National Electronic Injury Surveillance System from 2000-2013. National estimates of injuries were determined using complex sample design. Trends using 2-year intervals were calculated using linear regression and injury proportion ratios using Pearson's X2. The average annual incidence of dance-related injuries requiring emergency medical attention was 17,145 per year. The number of injuries grew from 14,204 in 2000/1 to 21,356 in 2012/3, a change of 33.4% after accounting for population growth. Lower limb injuries were most common, particularly ankle and knee sprains. Females presented with a greater proportion of ankle (injury proportion ratio [IPR]=1.34, p=0.029) and foot sprains (IPR=2.11, p<0.001) but a lower proportion of shoulder sprains (IPR=0.41, p<0.001) and face lacerations (IPR=0.13, p<0.001). Younger dancers presented with a lower proportion of knee (IPR=0.79, p=0.006) and low back sprains (IPR=0.68, p=0.019). The average annual incidence of dance-related injuries of a serious enough nature to require presentation to the emergency department in the United States was 17,145 per year, with ankle and knee sprains being the most common. Injury numbers have increased in recent years.

    To quantify and compare the incidence of lower extremity injuries in skiers and snowboarders who present to emergency rooms in the United States. Cross-sectional study of lower extremity injuries in skiers and snowboarders that were evaluated in emergency rooms in the United States. The National Electric Injury Surveillance System (NEISS) database was queried from January 1st, 2014 and December 31st, 2014 and the reported cases of lower extremity injuries in skiers and snowboarders were examined. An estimated total of 13,381 snow skiing and 6061 snowboarding lower extremity injuries presented to the emergency department in 2014 representing a national incidence of 42 injuries per 1,000,000 person-years for skiers and 19 injuries for snowboarders. The most common region of the lower extremity that was injured was the knee for skiers (47%) and the lower trunk (e.g. pelvis, hip, lumbar spine) for snowboarders (34%). The incidence of injuries in the pediatric and young adult population in skiers (62 per 1,000,000 person-years) and snowboarders (40 per 1,000,000 person-years) was significantly higher than the incidence of these injuries in adult population (35 and 12 per 1,000,000 person-years respectively) (Psnowboarding (30 per 1,000,000 person-years vs. 9 per 1,000,000 person-years, P snowboarding injuries down trended approaching significance. The incidence of lower extremity injuries in skiers was higher than that of snowboarders in 2014, with the 0-19year old age group and males being those most likely to sustain an injury. The most common region of the lower extremity that was injured was the knee for skiers and the lower trunk (e.g. pelvis, hip, lumbar spine) for snowboarders. Physicians and consumers alike should be aware of this data when considering participation in these sports as well as strategies for injury prevention. Copyright © 2016 Elsevier Ltd.

    The goal of this study was to determine the epidemiology of injuries associated with nursery products among young children treated in US emergency departments. Data from the National Electronic Injury Surveillance System were retrospectively analyzed for patients aged injuries among children aged injuries per 10 000 children. The annual injury rate decreased significantly by 33.9% from 1991 to 2003, followed by a significant increase of 23.7% from 2003 to 2011. The decrease was driven by a significant decline in baby walker/jumper/exerciser-related injuries; the increase was driven by a significant increase in concussions and closed head injuries. Nursery product-related injuries were most commonly associated with baby carriers (19.5%), cribs/mattresses (18.6%), strollers/carriages (16.5%), or baby walkers/jumpers/exercisers (16.2%). The most common mechanism of injury was a self-precipitated fall (80.0%), and the most frequently injured body region was the head or neck (47.1%). Although successful injury prevention efforts with baby walkers led to a decline in nursery product-related injuries from 1991 to 2003, the number and rate of these injuries have been increasing since 2003. Greater efforts are warranted to prevent injuries associated with other nursery products, especially baby carriers, cribs, and strollers. Prevention of falls and concussions/closed head injuries associated with nursery products also deserves special attention. Copyright © 2017 by the American Academy of Pediatrics.

    Full Text Available Objective: The objective of this study was to analyze cases that had left the Pediatric Emergency Center Al Sadd, Doha (PEC against medical advice, with the aim of developing policies to help reduce this occurrence. Methodology: All patients that were admitted to the main PEC observation room for treatment and/or investigation and subsequently left against medical advice from February 18, 2007 to June 18, 2007, were followed by a phone call, and a questionnaire, which was completed by the departmental patient representative. Results: 99,133 patients attended the facility during the study period. Of those, 106 left the facility against medical advice. Ninety-four guardians were successfully contacted. 90% of the cases were in children below 2 years of age. In 87% of the cases the mother was the main decision maker for leaving against medical advice. Domestic obligations were the leading cause of DAMA (discharge against medical advice, reported in 45% of the cases. Respondents reported that the consequences of DAMA were well explained by medical staff before they left the facility however, they had not met with the departmental patient representative during their stay. Conclusion:As the majority of DAMA cases occurred in infants, medical staff should address the concerns of this group early on in the course of treatment. Maintaining communication and providing support, in particular for mothers of higher risk groups may help to reduce the rate of DAMA cases.

    Over the last few decades obesity has become a major health issue worldwide. Although dietary and lifestyle changes are the cornerstone of obesity management, it still poses a huge challenge for the majority of patients to permanently change their eating habits. Bariatric endoscopy represents an evolving filed of minimally invasive techniques and procedures for weight loss trying to respond to these challenges by developing new methods with the increasing role of endoscopists in the management of obesity. Areas covered: The aim of this article is to review the role and the advantages of bariatric endoscopy in the management of obesity by providing a comprehensive reference source and evaluating the currently available and emerging endoscopic devices and techniques for weight loss. Expert commentary: Endoscopic methods for weight loss represent a useful armamentarium in the management of obesity by providing improved effectiveness compared with medications, with a lower risk profile than traditional bariatric surgery. Although preliminary results of recently introduced methods are encouraging, many questions remain regarding the safety and efficacy of such interventions. Combining scientific background with advancements in technology is the key strategy for the further development of bariatric endoscopy.

    Over the past two decades, neonicotinoid seed treatments have become the primary method to manage tobacco thrips, Frankliniella fusca Hinds, on seedling cotton. Because this insect is highly polyphagous and the window of insecticide exposure is short, neonicotinoid resistance was expected to pose a minimal risk. However, reports of higher than expected F. fusca seedling damage in seed-treated cotton fields throughout the Mid-South and Southeast US production regions suggested neonicotinoid resistance had developed. To document this change, F. fusca populations from 86 different locations in the eastern United States were assayed in 2014 and 2015 for imidacloprid and thiamethoxam resistance to determine the extent of the issue in the region. Approximately 57 and 65% of the F. fusca populations surveyed had reduced imidacloprid and thiamethoxam sensitivity respectively. Survivorship in diagnostic bioassays was significantly different at both the state and regional scales. Multiple-dose bioassays conducted on 37 of the populations documented up to 55- and 39-fold resistance ratios for imidacloprid and thiamethoxam respectively. Estimates of neonicotinoid resistance indicate an emerging issue for management of F. fusca in the eastern United States. Significant variation in survivorship within states and regions indicated that finer-scale surveys were needed to determine factors (genetic, insecticide use) driving resistance evolution. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    Stemming from current emerging paradigms related to the cancer stem cell hypothesis, an existing mathematical model is expanded and used to study cell interaction dynamics in the bone marrow and peripheral blood. The proposed mathematical model is described by a system of nonlinear differential equations with delay, to quantify the dynamics in abnormal hematopoiesis. The steady states of the model are analytically and numerically obtained. Some conditions for the local asymptotic stability of such states are investigated. Model analyses suggest that malignancy may be irreversible once it evolves from a nonmalignant state into a malignant one and no intervention takes place. This leads to the proposition that a great deal of emphasis be placed on cancer prevention. Nevertheless, should malignancy arise, treatment programs for its containment or curtailment may have to include a maximum and extensive level of effort to protect normal cells from eventual destruction. Further model analyses and simulations predict that in the untreated disease state, there is an evolution towards a situation in which malignant cells dominate the entire bone marrow - peripheral blood system. Arguments are then advanced regarding requirements for quantitatively understanding cancer stem cell behavior. Among the suggested requirements are, mathematical frameworks for describing the dynamics of cancer initiation and progression, the response to treatment, the evolution of resistance, and malignancy prevention dynamics within the bone marrow - peripheral blood architecture.

    The viability of modular pumped storage hydro (m-PSH) is examined in detail through the conceptual design, cost scoping, and economic analysis of three case studies. Modular PSH refers to both the compactness of the project design and the proposed nature of product fabrication and performance. A modular project is assumed to consist of pre-fabricated standardized components and equipment, tested and assembled into modules before arrival on site. This technology strategy could enable m-PSH projects to deploy with less substantial civil construction and equipment component costs. The concept of m-PSH is technically feasible using currently available conventional pumping and turbine equipment, and may offer a path to reducing the project development cycle from inception to commissioning.

    To provide national estimates of nonfatal outdoor recreational injuries treated in US emergency departments (EDs). Outdoor recreational injuries from January 2004 through December 2005 were identified using the National Electronic Injury Surveillance System-All Injury Program, a nationally representative sample of ED visits. National estimates of outdoor recreational injuries were calculated, and activities leading to injury, demographic characteristics, principal diagnoses, and primary body parts affected were described. From January 2004 through December 2005, an estimated 212 708 (95% CI = 113 808- 311 608) persons were treated each year in US EDs for outdoor recreational injuries. The annual rate of injuries was 72.1 per 100 000 population (95% CI = 38.6-105.6). Males accounted for 68.2% of the injuries. The lower limb (27%), upper limb (25%), and head and neck region (23.3%) were the most commonly injured body regions. Fractures (27.4%) and sprains or strains (23.9%) were the most common diagnoses. Traumatic brain injuries were diagnosed in 6.5% of injuries, and 5% of injuries resulted in hospitalization or transfer to another hospital. The results of this study provide a starting point for further research into the epidemiology of outdoor and wilderness injury. The results reinforce many common perceptions about the nature of these injuries while highlighting the potential severity and long-term consequences of the injuries. The general recommendations of proper planning, preparation, and problem anticipation for outdoor and wilderness injury prevention should be followed to reduce both the number and severity of injuries.

    In the United States, ticks transmit the greatest diversity of arthropod-borne pathogens and are responsible for the most cases of all vector-borne diseases. In recent decades, the number of reported cases of notifiable tick-borne diseases has steadily increased, geographic distributions of many ticks and tick-borne diseases have expanded, and new tick-borne disease agents have been recognized. In this review, we (1) describe the known disease agents associated with the most commonly human-biting ixodid ticks, (2) review the natural histories of these ticks and their associated pathogens, (3) highlight spatial and temporal changes in vector tick distributions and tick-borne disease occurrence in recent decades, and (4) identify knowledge gaps and barriers to more effective prevention of tick-borne diseases. We describe 12 major tick-borne diseases caused by 15 distinct disease agents that are transmitted by the 8 most commonly human-biting ixodid ticks in the United States. Notably, 40% of these pathogens were described within the last two decades. Our assessment highlights the importance of animal studies to elucidate how tick-borne pathogens are maintained in nature, as well as advances in molecular detection of pathogens which has led to the discovery of several new tick-borne disease agents.

    Trauma is the leading cause of death from ages 1-44-y in the United States and the fifth leading cause of death overall, but there are few studies quantifying trauma education in medical school. This study reviews curriculum hours devoted to trauma education at a northeastern medical school. We reviewed the preclinical curriculum at a northeastern medical school affiliated with three adult and two pediatric level I trauma centers verified by the American College of Surgeons. We reviewed curricular hours and we categorized them according to the leading ten causes of death in the United States. We also compared the number of educational hours devoted to trauma to other leading causes of death. The total amount of time devoted to trauma education in the first 2 y of medical school was 6.5 h. No lectures were given on the fundamentals of trauma management, traumatic brain injury, or chest or abdominal trauma. The most covered topic was heart disease (128 h), followed by chronic lower respiratory disease (80 h). Curricular time for heart disease, chronic lower respiratory disease, cancer, diabetes, renal disease, and influenza and pneumonia far exceeded that devoted to trauma, after adjusting for the mortality burden of these diseases (P curriculum might not be sufficient to expose students to the fundamentals of trauma management. A broader multi-institutional study may shed more insight on these curricular deficiencies in trauma education and detect if these deficiencies are widespread nationally. Published by Elsevier Inc.

    The increase in natural and man-made disasters occurring worldwide places Emergency Medicine (EM) physicians at the forefront of responding to these crises. Despite the growing interest in Disaster Medicine, it is unclear if resident training has been able to include these educational goals. Hypothesis This study surveys EM residencies in the United States to assess the level of education in Disaster Medicine, to identify competencies least and most addressed, and to highlight effective educational models already in place. The authors distributed an online survey of multiple-choice and free-response questions to EM residency Program Directors in the United States between February 7 and September 24, 2014. Questions assessed residency background and details on specific Disaster Medicine competencies addressed during training. Out of 183 programs, 75 (41%) responded to the survey and completed all required questions. Almost all programs reported having some level of Disaster Medicine training in their residency. The most common Disaster Medicine educational competencies taught were patient triage and decontamination. The least commonly taught competencies were volunteer management, working with response teams, and special needs populations. The most commonly identified methods to teach Disaster Medicine were drills and lectures/seminars. There are a variety of educational tools used to teach Disaster Medicine in EM residencies today, with a larger focus on the use of lectures and hospital drills. There is no indication of a uniform educational approach across all residencies. The results of this survey demonstrate an opportunity for the creation of a standardized model for resident education in Disaster Medicine.

For each of these applications, proper energy storage technologies are foreseen, with their advantages, disadvantages and limits. As electricity cannot be stored cheaply in large quantities, energy has to be stored in another form (chemical, thermal, electromagnetic, mechanical) and then converted back into electric power and/or energy using conversion systems. Most of the storage technologies are examined: b

    In the United States we generate greater than 500 million tons of toxic waste per year which pose a threat to human health and the environment. Some of the most toxic of these wastes are those that are radioactively contaminated. This thesis explores the need for permanent disposal facilities to isolate radioactive waste materials that are being stored temporarily, and therefore potentially unsafely, at generating facilities. Because of current controversies involving the interstate transfer of toxic waste, more states are restricting the flow of wastes into - their borders with the resultant outcome of requiring the management (storage and disposal) of wastes generated solely within a state`s boundary to remain there. The purpose of this project is to study nuclear waste storage issues and public perceptions of this important matter. Temporary storage at generating facilities is a cause for safety concerns and underscores, the need for the opening of permanent disposal sites. Political controversies and public concern are forcing states to look within their own borders to find solutions to this difficult problem. Permanent disposal or retrievable storage for radioactive waste may become a necessity in the near future in Colorado. Suitable areas that could support - a nuclear storage/disposal site need to be explored to make certain the health, safety and environment of our citizens now, and that of future generations, will be protected.

    Using first-principles calculations, we investigate the electronic and vibrational properties of monolayer As and AsSb. While the pristine monolayers are semiconductors (direct band gap at the Γ point), fluorination results in Dirac cones at the K points. Fluorinated monolayer As shows a band gap of 0.16 eV due to spin-orbit coupling, and fluorinated monolayer AsSb a larger band gap of 0.37 eV due to inversion symmetry breaking. Spin-orbit coupling induces spin splitting similar to monolayer MoS2. Phonon calculations confirm that both materials are dynamically stable. Calculations of the edge states of nanoribbons by the tight-binding method demonstrate that fluorinated monolayer As is topologically nontrivial in contrast to fluorinated monolayer AsSb.

    The increased frequency and severity of large wildfires in the western United States is an important ecological and management issue with direct relevance to amphibian conservation. Although the knowledge of fire effects on amphibians in the region is still limited relative to most other vertebrate species, we reviewed the current literature to determine if there are evident patterns that might be informative for conservation or management strategies. Of the seven studies that compared pre- and post-wildfire data on a variety of metrics, ranging from amphibian occupancy to body condition, two reported positive responses and five detected negative responses by at least one species. Another seven studies used a retrospective approach to compare effects of wildfire on populations: two studies reported positive effects, three reported negative effects from wildfire, and two reported no effects. All four studies that included plethodontid salamanders reported negative effects on populations or individuals; these effects were greater in forests where fire had been suppressed and in areas that burned with high severity. Species that breed in streams are also vulnerable to post-wildfire changes in habitat, especially in the Southwest. Wildfire is also important for maintaining suitable habitat for diverse amphibian communities, although those results may not be evident immediately after an area burns. We expect that wildfire will extirpate few healthy amphibian populations, but it is still unclear how populations will respond to wildfire in the context of land management (including pre- and post-fire timber harvest) and fragmentation. Wildfire may also increase the risk of decline or extirpation for small, isolated, or stressed (e.g., from drought or disease) populations. Improved understanding of how these effects vary according to changes in fire frequency and severity are critical to form more effective conservation strategies for amphibians in the western United States.

  10. A Study of Emergency Management Policy Regarding the Use of Tornado Sirens during Severe Weather in the State of Missouri

    Ebner, Nicholas William

    In recent years there have been many devastating tornadoes which have hit cities of all sizes across the state of Missouri, including St. Louis (April 22, 2011) rated EF 4, Joplin (May 22, 2011) rated EF 5 and Sedalia (May 25, 2011) rated EF-2. These, along with other catastrophic tornadoes in cities such as Tuscaloosa and Birmingham, Alabama, have increased the conversation regarding public policy of the use of tornado sirens. In many Missouri counties, guidelines and procedures regarding when to warn the public are inconsistent. After the media, emergency management directors and tornado sirens are the largest source and fastest way of informing the public of impending severe weather with the capability of producing tornadoes. With inconsistencies from county to county in Missouri and a lack of oversight by the state, uncertain and unregulated policies can cause citizens to be confused as to the specific meaning of these sirens. These variations in policy can range from who has responsibility over siren activation to the circumstances in which sirens are sounded. Frequently, in these time-sensitive situations, emergency managers do not have the sole responsibility of when to sound sirens. This decision is often left up to an assortment of individuals such as the police or fire department. It is well documented that citizens have become desensitized to tornado sirens based on the frequent number of soundings that have proven either to be a false alarm or siren activation provoked by other non-tornadic weather events. This occurs because many counties use their tornado sirens for reasons other than to alert citizens specifically of the immediate threat of tornadoes. Using a survey and archival research to gather information such as the jurisdiction policies on who activates sirens and the activation guidelines, a better understanding of how the warning process throughout Missouri was achieved. Suggestions are made that can be used by Emergency Management Directors

    A recently proposed technique in storage ring accelerators is applied to provide potential high-power sources of photon radiation. The technique is based on the steady-state microbunching (SSMB) mechanism. As examples of this application, one may consider a high-power DUV photon source for research in atomic and molecular physics or a high-power EUV radiation source for industrial lithography. A less challenging proof-of-principle test to produce IR radiation using an existing storage ring is also considered.

    This report presents final technical results for the project Geomechanical Framework for Secure CO2 Storage in Fractured Reservoirs and Caprocks for Sedimentary Basins in the Midwest United States (DE-FE0023330). The project was a three-year effort consisting of seven technical tasks focused on defining geomechanical factors for CO2 storage applications in deep saline rock formations in Ohio and the Midwest United States, because geomechancial issues have been identified as a significant risk factor for large-scale CO2 storage applications. A basin-scale stress-strain analysis was completed to describe the geomechanical setting for rock formations of Ordovician-Cambrian age in Ohio and adjacent areas of the Midwest United States in relation to geologic CO2 storage applications. The tectonic setting, stress orientation-magnitude, and geomechanical and petrophysical parameters for CO2 storage zones and caprocks in the region were cataloged. Ten geophysical image logs were analyzed for natural fractures, borehole breakouts, and drilling-induced fractures. The logs indicated mostly less than 10 fractures per 100 vertical feet in the borehole, with mostly N65E principal stress orientation through the section. Geophysical image logs and other logs were obtained for three wells located near the sites where specific models were developed for geomechanical simulations: Arches site in Boone County, Kentucky; Northern Appalachian Basin site in Chautauqua County, New York; and E-Central Appalachian Basin site in Tuscarawas County, Ohio. For these three wells, 9,700 feet of image logs were processed and interpreted to provide a systematic review of the distribution within each well of natural fractures, wellbore breakouts, faults, and drilling induced fractures. There were many borehole breakouts and drilling-induced tensile fractures but few natural fractures. Concentrated fractures were present at the Rome-basal sandstone

    DISCOVER-AQ (Deriving Information on Surface conditions from Column and Vertically Resolved Observations Relevant to Air Quality) is a NASA-funded air quality research program that focused on Houston, Texas, United States in September 2013. In conjunction with DISCOVER-AQ, particulate matter was collected for the month of September from four ground-based sampling sites across the Houston metropolitan area. The Houston metropolitan area is one of the most populous cities in the United States. Sampling sites included an upwind and downwind site as well as an urban (i.e. downtown) and industrial/port areas (i.e. Houston Ship Channel). Particulate matter samples were collected to examine both spatial and temporal trends (including day versus night). Particulate matter was collected on quartz fiber filters, which were analyzed for emerging classes of concern including organophosphate esters (OPEs; including flame retardants) and pyrethroids. OPEs have in recent years increased in both use and production as they replaced polybrominated diphenyl ethers flame retardants. Permethrin is one of the most commonly used mosquito adulticides in the United States.

    Full Text Available It is a great challenge for DC microgrids with stochastic renewable sources and volatility loads to achieve better operation performance. This study proposes an energy management strategy based on multiple operating states for a DC microgrid, which is comprised of a photovoltaic (PV array, a proton exchange membrane fuel cell (PEMFC system, and a battery bank. This proposed strategy can share the power properly and keep the bus voltage steady under different operating states (the state of charge (SOC of the battery bank, loading conditions, and PV array output power. In addition, a microgrids test platform is established. In order to verify the effectiveness of the proposed energy management strategy, the strategy is implemented in a hardware system and experimentally tested under different operating states. The experimental results illustrate the good performance of the proposed control strategy for the DC microgrid under different scenarios of power generation and load demand.

    To provide nationally representative estimates of hospital-based emergency department visits (ED) for dental caries, pulp and periapical lesions, gingival/periodontal lesions, and mouth cellulitis occurring among patients who were 21 years old and younger. Nationwide Emergency Department Sample (NEDS) for the year 2008 was used. All ED visits with dental conditions were included. Discharge patterns, demographics, disposition following ED visit, and hospital charges, were examined. NEDS is a uniform, stratified dataset, and can be projected to the national level. A total of 215,073 ED visits with dental conditions occurred among children. These visits included diagnosis of dental caries (50 percent of visits), pulpal and periapical conditions (41 percent), gingival (15 percent) and periodontal diseases (five percent), and mouth abscess/cellulitis (three percent). Forty-two percent were covered by Medicaid, and 32 percent were uninsured. Mean charge per visit was $564, and total ED charge across the United States (US) was $104.2 million. Among those hospitalized following ED visits, total hospitalization charge across US was $162 million. A substantial amount of hospital resources are spent treating dental conditions in the ED. A total of 43 percent of ED visits were covered by Medicaid, and 32 percent were uninsured.

    By 1883 a Veterinary Division had been established within the United States Department of Agriculture, itself established in 1862. Federal concern about animal health in the U.S.A. emerged as early as 1865 when Congress adopted regulations aimed at controlling importation of livestock. It was not until 1884 that the Bureau of Animal Industry (BAI) was formally created by Act of Congress, and shortly after that the Zoological Laboratory was established and assigned responsibility for study of parasites and the diseases they produce in animals. Classically trained parasitologists working in USDA's BAI soon became internationally recognized for their contributions to basic research and development of programs for prevention and control of parasitic diseases. Leadership by a series of BAI-employed parasitologists led to the emergence of veterinary parasitology as a sub-discipline. Maurice C. Hall who served as president of both the American Society of Parasitologists and the American Veterinary Medical Association was a central figure in development of veterinary parasitology in the U.S.A., which flourished in his country and elsewhere today.

    To extend the assessment of a special messaging technology with two adults emerged from a minimally conscious state and showing extensive motor disabilities as well as limited or no oral/verbal skills. The study involved a non-concurrent multiple baseline design across participants. Both participants started with baseline in which the technology was not available, and continued with intervention in which the technology was used. The technology involved a net-book computer provided with specific software, a global system for mobile communication (GSM) modem, microswitches, and pre-recorded lists of persons and messages. Both participants learned to send out and receive (listen to) messages independently during the intervention. They sent out a mean of three or three and a half messages and received a mean of one and a half messages per 20-minute session. Special messaging technology may help post-coma persons with multiple disabilities engage in basic communication with distant partners.

    We evaluated the effectiveness of text messaging versus email, as a delivery method to enhance knowledge retention of emergency medicine (EM) content in EM residents. We performed a multi-centered, prospective, randomized study consisting of postgraduate year (PGY) 1 to PGY 3 & 4 residents in three United States EM residency programs in 2014. Fifty eight residents were randomized into one delivery group: text message or email. Participants completed a 40 question pre- and post-intervention exam. Primary outcomes were the means of pre- and post-intervention exam score differences. Data were analyzed using descriptive statistics, paired t-test, and multiple linear regressions. No significant difference was found between the primary outcomes of the two groups (P=0.51). PGY 2 status had a significant negative effect (P=0.01) on predicted exam score difference. Neither delivery method enhanced resident knowledge retention. Further research on implementation of mobile technology in residency education is required.

    Pachycondyla chinensis (Emery) (Formicidae: Ponerinae), a species introduced into North America > 70 yr ago, is found throughout Southeast Asia. Stinging of zookeepers by P. chinensis at the Greenville Zoo (Greenville, SC) initiated an investigation of this exotic species and a survey of sting victims. Eighty percent of sting victims experienced local reactions, including swelling 5 cm in diameter around the sting site, recurring pain, skin redness, severe urticaria, and symptoms lasting 3-14 d. P. chinensis represents an emerging public health threat throughout its present range in the southeastern United States (i.e., Georgia, North Carolina, South Carolina, and Virginia). Because of reported adverse reactions to stings of P. chinensis, further studies on its ecology and medical and veterinary importance need to be undertaken.

    Solar energy technology becomes more and more important for space and water heating of residential buildings. Compared to small systems for single-family houses, the specific investment cost of big solar plants is lower and a higher contribution of solar energy can be achieved. In central solar heating plants with seasonal storage (CSHPSS), more than 50% of the total heat demand of residential areas can be covered by solar energy. The first pilot plants for CSHPSS are operating in Germany since 1996. The first results of the accompanying monitoring program show good agreement between calculated and actual solar contribution.

  1. Emergency room validation of the revised Suicide Trigger Scale (STS-3: a measure of a hypothesized suicide trigger state.

    Directory of Open Access Journals (Sweden)

    Zimri S Yaseen

    Full Text Available BACKGROUND: The Suicide Trigger Scale (STS was designed to measure the construct of an affective 'suicide trigger state.' This study aims to extend the inpatient setting validation study of the original Suicide Trigger Scale version 2 to the revised Suicide Trigger Scale version 3 (STS-3 in an acute psychiatric emergency room setting. METHODS: The 42-item STS-3 and a brief psychological test battery were administered to 183 adult psychiatric patients with suicidal ideation or attempt in the psychiatric emergency room, and re-administered to subjects at 1 year follow up. Factor analysis, linear and logistic regressions were used to examine construct structure, divergent and convergent validity, and construct validity, respectively. RESULTS: The STS-3 demonstrated strong internal consistency (Cronbach's alpha 0.94. Factor analysis yielded a three-factor solution, which explained 43.4% of the variance. Principal axis factor analysis was used to identify three reliable subscales: Frantic Hopelessness, Ruminative Flooding, and Near-Psychotic Somatization (Cronbach's alphas 0.90, 0.80, and 0.76, respectively. Significant positive associations were observed between Frantic Hopelessness and BSI depression and anxiety subscales, between Ruminative Flooding and BSI anxiety and paranoia subscales, and Near Psychotic Somatization and BSI somatization subscales. Suicidal subjects with suicide attempt history had mean scores 7 points higher than those without history of suicide attempts. Frantic hopelessness was a significant predictor of current suicide attempt when only attempts requiring at least some medical attention were considered. CONCLUSION: The STS-3 measures a distinct clinical entity, provisionally termed the 'suicide trigger state.' Scores on the STS-3 or select subscales appear to relate to degree of suicidality in terms of severity of ideation, history of attempt, and presence of substantive current attempts. Further study is required to

    Erionite, a mineral series within the zeolite group, is classified as a Group 1 known respiratory carcinogen. This designation resulted from extremely high incidences of mesothelioma discovered in three small villages from the Cappadocia region of Turkey, where the disease was linked to environmental exposures to fibrous forms of erionite. Natural deposits of erionite, including fibrous forms, have been identified in the past in the western United States. Until recently, these occurrences have generally been overlooked as a potential hazard. In the last several years, concerns have emerged regarding the potential for environmental and occupational exposures to erionite in the United States, such as erionite-bearing gravels in western North Dakota mined and used to surface unpaved roads. As a result, there has been much interest in identifying locations and geologic environments across the United States where erionite occurs naturally. A 1996 U.S. Geological Survey report describing erionite occurrences in the United States has been widely cited as a compilation of all US erionite deposits; however, this compilation only focused on one of several geologic environments in which erionite can form. Also, new occurrences of erionite have been identified in recent years. Using a detailed literature survey, this paper updates and expands the erionite occurrences database, provided in a supplemental file (US_erionite.xls). Epidemiology, public health, and natural hazard studies can incorporate this information on known erionite occurrences and their characteristics. By recognizing that only specific geologic settings and formations are hosts to erionite, this knowledge can be used in developing management plans designed to protect the public.

  4. Leveraging Regional Exploration to Develop Geologic Framework for CO2 Storage in Deep Formations in Midwestern United States

    Obtaining subsurface data for developing a regional framework for geologic storage of CO{sub 2} can require drilling and characterization in a large number of deep wells, especially in areas with limited pre-existing data. One approach for achieving this objective, without the prohibitive costs of drilling costly standalone test wells, is to collaborate with the oil and gas drilling efforts in a piggyback approach that can provide substantial cost savings and help fill data gaps in areas that may not otherwise get characterized. This leveraging with oil/gas drilling also mitigates some of the risk involved in standalone wells. This collaborative approach has been used for characterizing in a number of locations in the midwestern USA between 2005 and 2009 with funding from U.S. Department of Energy's National Energy Technology Laboratory (DOE award: DE-FC26-05NT42434) and in-kind contributions from a number of oil and gas operators. The results are presented in this final technical report. In addition to data collected under current award, selected data from related projects such as the Midwestern Regional Carbon Sequestration Partnership (MRCSP), the Ohio River Valley CO{sub 2} storage project at and near the Mountaineer Plant, and the drilling of the Ohio Stratigraphic well in Eastern Ohio are discussed and used in the report. Data from this effort are also being incorporated into the MRCSP geologic mapping. The project activities were organized into tracking and evaluation of characterization opportunities; participation in the incremental drilling, basic and advanced logging in selected wells; and data analysis and reporting. Although a large number of opportunities were identified and evaluated, only a small subset was carried into the field stage. Typical selection factors included reaching an acceptable agreement with the operator, drilling and logging risks, and extent of pre-existing data near the candidate wells. The region of study is primarily along

    The overall program goal is to perform a basic investigation of photoelectrochemical and electrochemical effects by electrochromic materials in solid polymer electrolyte (SPE) containing solid-state cells. Initial investigations have been directed towards reversible electrochromic behavior at the interface between lutecium diphthalocyanine deposited onto electronically conducting glass, and the homopolymer poly-2-acrylamido -2-methylpropane sulfonic acid (poly(Amps)). We wish to report here some recent work on solid-state electrochromic cells in which ionic mediation to thin-film deposits of lutecium diphthalocyanine is via the homopolymer poly-2-acrylamido-2-methyl propane sulfonic acid (poly-Amps). Separation between the working (LuH(Pc)2 deposited onto SnO2 conducting glass) and counter (CeCl3 in poly (Amps)) electrodes in these solid-state cells was realized by the use of the insoluble copolymer perfluorosulfonic acid (Nafion). Solid-state electrochromic cells were prepared using the supporting electrolytes (SEs) 0.1M Na2SO4 and 0.1M KCl. Upon subjecting the cell to anodic and cathodic voltage scans, up to four distinct color changes were observed varying from red (at anodic potentials) to violet (at cathodic potentials). Formation of the violet lutecium diphthalocyanine reduction product was not found contingent upon the absence of alkali cations as reported by others.

    Groundnut ringspot virus (GRSV) and Tomato chlorotic spot virus (TCSV) are two emerging tospoviruses in Florida. In a survey of the southeastern United States, GRSV and TCSV were frequently detected in solanaceous crops and weeds with tospovirus-like symptoms in south Florida, and occurred sympatrically with Tomato spotted wilt virus (TSWV) in tomato and pepper in south Florida. TSWV was the only tospovirus detected in other survey locations, with the exceptions of GRSV from tomato (Solanum lycopersicum) in South Carolina and New York, both of which are first reports. Impatiens (Impatiens walleriana) and lettuce (Lactuca sativa) were the only non-solanaceous GRSV and/or TCSV hosts identified in experimental host range studies. Little genetic diversity was observed in GRSV and TCSV sequences, likely due to the recent introductions of both viruses. All GRSV isolates characterized were reassortants with the TCSV M RNA. In laboratory transmission studies, Frankliniella schultzei was a more efficient vector of GRSV than F. occidentalis. TCSV was acquired more efficiently than GRSV by F. occidentalis but upon acquisition, transmission frequencies were similar. Further spread of GRSV and TCSV in the United States is possible and detection of mixed infections highlights the opportunity for additional reassortment of tospovirus genomic RNAs.

In the US, 45% of all pregnancies are either mistimed or unwanted. Mishaps with contraceptives, such as condom breakage, missed pills, incorrect timing of patch or vaginal ring application, contraceptive nonuse, forced intercourse, and other circumstances, place women at risk of unintended pregnancy. There is a critical role for emergency contraception (EC in preventing those pregnancies. There are currently three methods of EC available in the US. Levonorgestrel EC pills have been available with a prescription for over 15 years and over-the-counter since 2013. In 2010, ulipristal acetate EC pills became available with a prescription. Finally, the copper intrauterine device remains the most effective form of EC. Use of EC is increasing over time, due to wider availability and accessibility of EC methods. One strategy to expand access for both prescription and nonprescription EC products is to include pharmacies as a point of access and allow pharmacist prescribing. In eight states, pharmacists are able to prescribe and provide EC directly to women: levonorgestrel EC in eight states and ulipristal

Youth versus adult “weightlifting” injuries presenting to united states emergency rooms: accidental versus nonaccidental injury mechanisms. J Strength Cond Res 23(7): 2054–2060, 2009—Resistance training has previously been purported to be unsafe and ineffective in children. The purpose of this investigation was to evaluate resistance training-related injuries presenting to U.S. emergency rooms by age, type, and mechanism of injury. We hypothesized that older athletes would sustain greater percentages of joint sprains and muscle strains, whereas younger athletes would sustain a greater percentage of accidental injuries that would result in an increased percentage of fractures in youths. The U.S. Consumer Product Safety Commission (CPSC) National Electronic Injury Surveillance System was queried from 2002 to 2005 using the CPSC code for “Weightlifting.” Subjects between the ages of 8 and 30 were grouped by age categories 8 to 13 (elementary/middle school age), 14 to 18 (high school), 19 to 22 (college), and 23 to 30 (adult). Injuries were classified as “accidental” if caused by dropped weight or improper equipment use. Multiple logistic regression was used to compare accidental injuries between age groups. The sample consisted of 4, 111 patients. Accidental injuries decreased (p 14 to 18 > 19 to 22 years = 23 to 30 years. Conversely, sprain/strain injuries increased in each successive age group (p sprains and strains relative to younger age categories (p sprains and muscle strains than adults. The majority of youth resistance training injuries are the result of accidents that are potentially preventable with increased supervision and stricter safety guidelines. PMID:19855330

    The prevalence of atrial fibrillation (AF) is increasing in the United States as the population ages, but national surveillance is lacking. This cross-sectional study (2006 to 2014) analyzed data from the Healthcare Cost and Utilization Project's Nationwide Emergency Department Sample, the National (Nationwide) Inpatient Sample, and the National Vital Statistics System. Event totals were estimated independently for emergency department (ED) visits, hospitalizations, and mortality, and then collectively after applying criteria to identify mutually exclusive events. Rates were calculated for AF as primary diagnosis or underlying cause of death (primary AF), as well as secondary diagnosis or contributing cause of death (co-morbid AF), and standardized by age to the 2010 US population. From 2006 to 2014, event rates increased for primary AF (249 to 268 per 100,000) and co-morbid AF (1,473 to 1,835 per 100,000). In 2014, an estimated 599,790 ED visits, 453,060 hospitalizations, and 21,712 deaths listed AF as primary. A total of 684,470 mutually exclusive primary AF and 4,695,997 mutually exclusive co-morbid AF events occurred. Among ED visits and hospitalizations with primary AF, the most common secondary diagnoses were hypertension, heart failure, ischemic heart disease, and diabetes. The mean cost per hospitalization with primary AF was $8,819. Mean costs were higher for those with co-morbid AF versus those without co-morbid AF among hospitalizations with a primary diagnosis of ischemic heart disease, heart failure, stroke, hypertension, or diabetes (all p ≤0.01). In conclusion, with the substantial health and economic impact of AF and an aging US population, improved diagnosis, prevention, management, and surveillance of AF are increasingly important.

    Solid state amide hydrogen/deuterium exchange with mass spectrometric analysis (ssHDX-MS) was used to assess the conformation of myoglobin (Mb) in lyophilized formulations, and the results correlated with the extent of aggregation during storage. Mb was colyophilized with sucrose (1:1 or 1:8 w/w), mannitol (1:1 w/w), or NaCl (1:1 w/w) or in the absence of excipients. Immediately after lyophilization, samples of each formulation were analyzed by ssHDX-MS and Fourier transform infrared spectroscopy (FTIR) to assess Mb conformation, and by dynamic light scattering (DLS) and size exclusion chromatography (SEC) to determine the extent of aggregation. The remaining samples were then placed on stability at 25 °C and 60% RH or 40 °C and 75% RH for up to 1 year, withdrawn at intervals, and analyzed for aggregate content by SEC and DLS. In ssHDX-MS of samples immediately after lyophilization (t = 0), Mb was less deuterated in solids containing sucrose (1:1 and 1:8 w/w) than in those containing mannitol (1:1 w/w), NaCl (1:1 w/w), or Mb alone. Deuterium uptake kinetics and peptide mass envelopes also indicated greater Mb structural perturbation in mannitol, NaCl, or Mb-alone samples at t = 0. The extent of deuterium incorporation and kinetic parameters related to rapidly and slowly exchanging amide pools (Nfast, Nslow), measured at t = 0, were highly correlated with the extent of aggregation on storage as measured by SEC. In contrast, the extent of aggregation was weakly correlated with FTIR band intensity and peak position measured at t = 0. The results support the use of ssHDX-MS as a formulation screening tool in developing lyophilized protein drug products.

    Full Text Available Objectives. This study was designed to compare the trainees’ perception of emergency medicine (EM training in the United States (US and Saudi Arabia (SA and to identify residents’ levels of confidence and points of satisfaction in education, procedural skills, and work environment. Method. An IRB-exempt anonymous web-based survey was distributed to five EM residency training programs in the USA and three residency regions in SA. Results. 342 residents were polled with a 20% response rate (16.8% USA and 25.8% SA. The Saudi residents responded less positively to the questions about preparation for their boards’ examinations, access to multiple educational resources, and weekly academic activities. The Saudi trainees felt less competent in less common procedures than US trainees. American trainees also more strongly agree that they have more faculty interest in their education compared to the Saudi trainees. The Saudi residents see more patients per hour compared to their US peers. Conclusion. These findings may be due to the differences in training techniques including less formal didactics and simulation experience in SA and more duty hour regulations in the USA.

    The objective of this article is to report psychometric characteristics of the AUDIT, CAGE, RAPS4, and TWEAK and to compare them across three countries: Argentina, Mexico, and the United States which used a similar protocol and methodology. Probability samples of patients 18 years and older were drawn from emergency departments in Mar del Plata, Argentina (n=780), Pachuca, Mexico (n=1624) and Santa Clara, U.S. (n=1220). Concurrent validity was assessed by comparing their performance against a diagnosis of alcohol dependence (DSM-IV) obtained through the Composite International Diagnostic Interview, and for the briefer measures, also by their correlation with the AUDIT. The internal consistency of the CAGE, RAPS4, and TWEAK scores was estimated by the KR-20 formula and by Cronbach's Alpha for the AUDIT. Corrected item-total correlation and D-values were used as item discrimination measures. In Argentina and Mexico the AUDIT and the RAPS4 showed the highest validity. Reliability of all instruments was higher in the US than in Argentina or Mexico. In all three countries, reliability of the TWEAK was lowest, while the AUDIT was highest. With a few exceptions, all items showed good discrimination powers. Copyright 2010 Elsevier Ltd. All rights reserved.

    This study proposed the use of assistive technology (AT) to promote communication and leisure opportunities by three children with traumatic brain injury (TBI). Furthermore, it assessed the effects of such technology on the indices of positive participation and provided a social validation procedure. Three children emerged from a minimal conscious state and presenting extensive motor disabilities were involved. The intervention program allowed the participants to request and to choice preferred items independently and to perform literacy through a keyboard emulator. A multiple probe design across behaviors with post-intervention check was employed. Outcome measures were correct requests, understandable words, intervals with positive participation, and scores of social validation assessment. Request and choice behaviors and literacy improved significantly during intervention phases. During post-intervention check, all participants consolidated their performance. Moreover, indices of positive participation increased during intervention phases. Scores of social validation assessment showed that the combination of both behaviors was preferable to the same considered separately. AT program showed to be suitable for promoting constructive engagement and literacy behaviors by children with TBI. Future research is needed to generalize this data to a larger sample and to develop new technology for people with different levels of disabilities due to TBI.

    Medical education is transitioning from traditional learning methods. Resident interest in easily accessible education materials is forcing educators to reevaluate teaching methodology. To determine emergency medicine residents' current methods of and preferences for obtaining medical knowledge, the authors created a survey and sent it to residents, at all levels of training throughout the United States, whose e-mail addresses were available via their residency's official Web site (June-December 2012). The eight-question voluntary survey asked respondents about demographics, their use of extracurricular time, and the materials they perceived as most beneficial. The authors used descriptive statistics to analyze results. Of the 401 residents who received the e-mailed survey, 226 (56.3%) completed it. Of these, 97.7% reported spending at least one hour per week engaging in extracurricular education, and 34.5% reported spending two to four hours per week (P journals (36.5%), and Google (33.8%; P educators must engage with current learners to guide appropriate use of these.

  19. The political extreme as the new normal: the cases of Brexit, the French state of emergency and Dutch Islamophobia

    2017-06-01

    Full Text Available In this article we carry out a geopolitical analysis of the turbulent breeze driving the EU into uncharted extremes. To do this we zoom in on three cases that we deem both a response to political extremism and a source of political extremism in themselves: France’s state of emergency, Brexit and the pyrrhic victory over the far-right in the Dutch elections of 2017 . Our analysis suggests that even though the political forces behind these events have praised their policies or electoral victories as bulwarks to keep extremism in check, the sort of extremism that they try to keep at bay is not as worrying as the counter-productive realpolitik of the traditional establishment they represent. By surreptitiously adopting precisely the kind of extremist political preferences that they claim to set themselves against, these politics show how the establishment in the EU is normalising the extreme geopolitics of exclusion that are structurally undermining the very principles of rule of law, liberal democracy and overall openness on which the EU is based. The result: what used to be easily dismissed as irrational or evil has become the everyday normal. The extremism we so much fear has become the new normality.

    Memory is a key component of any data processing system. Following the classical Turing machine approach, memories hold both the data to be processed and the rules for processing them. In the history of microelectronics, the distinction has been rather between working memory, which is exemplified by DRAM, and storage memory, exemplified by NAND. These two types of memory devices now represent 90% of all memory market and 25% of the total semiconductor market, and have been the technology drivers in the last decades. Even if radically different in characteristics, they are however based on the same storage mechanism: charge storage, and this mechanism seems to be near to reaching its physical limits. The search for new alternative memory approaches, based on more scalable mechanisms, has therefore gained new momentum. The status of incumbent memory technologies and their scaling limitations will be discussed. Emerging memory technologies will be analyzed, starting from the ones that are already present for niche applications, and which are getting new attention, thanks to recent technology breakthroughs. Maturity level, physical limitations and potential for scaling will be compared to existing memories. At the end the possible future composition of memory systems will be discussed.

    Research into leadership emergence typically focuses on the attributes of the emergent leader. By considering also the attributes of perceivers and the passage of time, we develop a more complete theory of leadership emergence in short-lived groups. Using expectation states theory as an overarching theoretical framework, and integrating it with the surface- and deep-level diversity literature and with theories of self-serving biases, we examine the predictors of leadership emergence in short timeframes. We conduct a field study in a military assessment boot camp (a pilot study, n = 60; and a main study, n = 89). We use cross-sectional and longitudinal exponential random graph models to analyze data on participants' abilities and on their perceptions of who, in their respective groups, were "leaders." We find that the criteria by which people perceive leadership in others change over time, from easily noticeable attributes to covert leadership-relevant attributes, and that people also rely on leadership-relevant attributes that they possess at high levels to inform their perceptions of leadership in others. The integration of expectation states theory, attribute salience over time and theories of self-serving bias is needed for a full understanding of leadership emergence in groups, because perceivers' own abilities are instrumental in shaping their perceptions of emergent leadership over time. Theoretical and practical implications are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    Carbonsheds are regions in which the estimated cost of transporting CO{sub 2} from any (plant) location in the region to the storage site it encompasses is cheaper than piping the CO{sub 2} to a storage site outside the region. We use carbonsheds to analyze the cost of transport and storage of CO{sub 2} in deploying CCS on land and offshore of the continental U.S. We find that onshore the average cost of transport and storage within carbonsheds is roughly $10/t when sources cooperate to reduce transport costs, with the costs increasing as storage options are depleted over time. Offshore transport and storage costs by comparison are found to be roughly twice as expensive but t may still be attractive because of easier access to property rights for sub-seafloor storage as well as a simpler regulatory system, and possibly lower MMV requirements, at least in the deep-ocean where pressures and temperatures would keep the CO{sub 2} negatively buoyant. Agent-based modeling of CCS deployment within carbonsheds under various policy scenarios suggests that the most cost-effective strategy at this point in time is to focus detailed geology characterization of storage potential on only the largest onshore reservoirs where the potential for mitigating emissions is greatest and the cost of storage appears that it will be among the cheapest.

    Full Text Available OBJECTIVES: To describe nationally representative outcomes of physical abuse injuries in children necessitating Emergency Department (ED visits in United States. The impact of various injuries on mortality is examined. We hypothesize that physical abuse resulting in intracranial injuries are associated with worse outcome. MATERIALS AND METHODS: We performed a retrospective analysis of the Nationwide Emergency Department Sample (NEDS, the largest all payer hospital based ED database, for the years 2008-2010. All ED visits and subsequent hospitalizations with a diagnosis of "Child physical abuse" (Battered baby or child syndrome due to various injuries were identified using ICD-9-CM (International Classification of Diseases, 9th Revision, Clinical Modification codes. In addition, we also examined the prevalence of sexual abuse in this cohort. A multivariable logistic regression model was used to examine the association between mortality and types of injuries after adjusting for a multitude of patient and hospital level factors. RESULTS: Of the 16897 ED visits that were attributed to child physical abuse, 5182 (30.7% required hospitalization. Hospitalized children were younger than those released treated and released from the ED (1.9 years vs. 6.4 years. Male or female partner of the child's parent/guardian accounted for >45% of perpetrators. Common injuries in hospitalized children include- any fractures (63.5%, intracranial injuries (32.3% and crushing/internal injuries (9.1%. Death occurred in 246 patients (13 in ED and 233 following hospitalization. Amongst the 16897 ED visits, 1.3% also had sexual abuse. Multivariable analyses revealed each 1 year increase in age was associated with a lower odds of mortality (OR = 0.88, 95% CI = 0.81-0.96, p < 0.0001.

    Energy storage technology is critical if the U.S. is to achieve more than 25% penetration of renewable electrical energy, given the intermittency of wind and solar. Energy density is a critical parameter in the economic viability of any energy storage system with liquid fuels being 10 to 100 times better than batteries. However, the economical conversion of electricity to fuel still presents significant technical challenges. This project addressed these challenges by focusing on a specific approach: efficient processes to convert electricity, water and nitrogen to ammonia. Ammonia has many attributes that make it the ideal energy storage compound. The feed stocks are plentiful, ammonia is easily liquefied and routinely stored in large volumes in cheap containers, and it has exceptional energy density for grid scale electrical energy storage. Ammonia can be oxidized efficiently in fuel cells or advanced Carnot cycle engines yielding water and nitrogen as end products. Because of the high energy density and low reactivity of ammonia, the capital cost for grid storage will be lower than any other storage application. This project developed the theoretical foundations of N2 catalysis on specific catalysts and provided for the first time experimental evidence for activation of Mo 2N based catalysts. Theory also revealed that the N atom adsorbed in the bridging position between two metal atoms is the critical step for catalysis. Simple electrochemical ammonia production reactors were designed and built in this project using two novel electrolyte systems. The first one demonstrated the use of ionic liquid electrolytes at room temperature and the second the use of pyrophosphate based electrolytes at intermediate temperatures (200 – 300 ºC). The mechanism of high proton conduction in the pyrophosphate materials was found to be associated with a polyphosphate second phase contrary to literature claims and ammonia production rates as high as 5X 10

    This paper analyzes the best mix of memories in a tri-hybrid solid-state drive (SSD) with storage class memory (SCM) and multi-level cell (MLC)/triple-level cell (TLC) NAND flash memory. SCM is fast but its cost is high. Although MLC NAND flash memory is slow, it is more cost effective than SCM. For further cost efficiency, TLC NAND flash memory is denser and less expensive than MLC NAND flash. Performance of tri-hybrid SSD is evaluated in various memory configurations. Moreover, the optimum memory configuration is changed according to the application characteristics. If 10% cost increase is allowed compared to the MLC NAND flash only SSD, SCM/MLC NAND flash hybrid SSD provides the best performance with hot/random workload, whereas SCM/MLC/TLC NAND flash tri-hybrid SSD achieves the best for hot/sequential and cold/random workloads. In addition, it is possible to add long latency but low-cost SCM to the tri-hybrid SSD. As a result, tri-hybrid SSD with slow SCM achieves the best performance.

    Malaria is one of the most serious and complex health problems in Sub Saharan Africa. Anemia in Children with malaria may require blood transfusion and has been be associated with high mortality rates. The aim of this study is to evaluate the prevalence, pattern, and severity of malaria parasitemia among children 6 months to 14 years old, requiring blood transfusion. This is a cross-sectional study carried out at the children emergency unit of the Imo state University Teaching Hospital South East Nigeria. Data were analyzed using SPSS version 21, Chicago Il, USA. A total of 409 children were recruited into the study. The overall rate of malaria parasitemia was 83.1% (340/409) lower in males 81.6% (228/276) than in females 86.3% (112/133). The peak of parasitemia is similar in both sexes (5-9 years). Most of the children had medium levels of parasitemia, which decreased with increasing age. The proportion of children transfused also decreased with increasing age. At medium and high levels of parasitemia; in children below 5 years, 92.8% (132/142) were transfused while in 5 years and above only 79.6% (39/49) of the children were transfused. At medium level parasitemia the proportion of children transfused was significantly higher than those not transfused (P transfusion. Targeted measures toward primary prevention of malaria in children should be intensified as this will not only reduce morbidity and mortality of malaria, but will reduce the economic burden of the disease in Semi-rural and rural dwellers in Sub Saharan Africa.

    Health care workers are more likely than most other occupations to experience work-related injuries, and emergency nurses frequently encounter job-related hazards in their daily routine. Risk factors for non-violence-related workplace injuries among nurses include heavy workloads, aging of the nursing workforce, workplace environmental factors, obesity, and non-standard work schedules. These factors impact nurses' decisions regarding whether or not to return to their job or to stay in their field of practice, thereby exacerbating workforce shortages and hindering recruitment and retention efforts. To better understand non-violence-related workplace injuries among emergency nurses, ENA conducted a survey of its members in 2009. Of the 2294 nurses who responded to the survey, one in five nurses (n = 440) reported that they experienced a non-violence-related injury while working in their emergency department during the previous year. The logistic regression model found three factors that were related to the occurrence of a non-violence-related workplace injury: (1) hospitals having safe patient handling policies and programs, (2) access to decontamination and post-exposure treatment, and (3) emergency nurses' perception of staffing in their emergency department. While these results provide only a preliminary understanding of ED non-violence-related workplace injuries, they form the basis of a fundamental model for prevention of workplace injuries among emergency nurses. The model can be used to help establish a culture of ED workplace safety through the integration of safety policies and programs, access to safety equipment and controls, and optimal staffing levels. Support from hospital administrators for ED workplace safety initiatives that address these three components, along with current best practice recommendations from the field of occupational health and safety, have the potential to improve workplace safety for emergency nurses.

    Computer simulation offers the ability to compare diverse interventions for reducing cardiovascular disease risks in a controlled and systematic way that cannot be done in the real world. We used the Prevention Impacts Simulation Model (PRISM) to analyze the effect of 50 intervention levers, grouped into 6 (2 x 3) clusters on the basis of whether they were established or emerging and whether they acted in the policy domains of care (clinical, mental health, and behavioral services), air (smoking, secondhand smoke, and air pollution), or lifestyle (nutrition and physical activity). Uncertainty ranges were established through probabilistic sensitivity analysis. Results indicate that by 2040, all 6 intervention clusters combined could result in cumulative reductions of 49% to 54% in the cardiovascular risk-related death rate and of 13% to 21% in risk factor-attributable costs. A majority of the death reduction would come from Established interventions, but Emerging interventions would also contribute strongly. A slim majority of the cost reduction would come from Emerging interventions. PRISM allows public health officials to examine the potential influence of different types of interventions - both established and emerging - for reducing cardiovascular risks. Our modeling suggests that established interventions could still contribute much to reducing deaths and costs, especially through greater use of well-known approaches to preventive and acute clinical care, whereas emerging interventions have the potential to contribute significantly, especially through certain types of preventive care and improved nutrition.

  3. From the American Civil War to the War on Terror: Three Models of Emergency Law in the United States Supreme Court

    Hartz, Emily

    This book offers a systematic and comprehensive account of the key cases that have come to shape the jurisprudence on emergency law in the United States from the Civil War to the War on Terror. The legal questions raised in these cases concern fundamental constitutional issues such as the status...... of fundamental rights, the role of the court in times of war, and the question of how to interpret constitutional limitations to executive power. At stake in these difficult legal questions is the issue of how to conceive of the very status of law in liberal democratic states. The questions with which...... the Supreme Court justices have to grapple in these cases are therefore as philosophical as they are legal. In this book the Court's arguments are systematized according to categories informed by constitutional law as well as classic philosophical discussions of the problem of emergency. On this basis...

  4. Investigation of multi-state charge-storage properties of redox-active organic molecules in silicon-molecular hybrid devices for DRAM and Flash applications

    Science.gov (United States)

    Gowda, Srivardhan Shivappa

    Molecular electronics has recently spawned a considerable amount of interest with several molecules possessing charge-conduction and charge-storage properties proposed for use in electronic devices. Hybrid silicon-molecular technology has the promise of augmenting the current silicon technology and provide for a transitional path to future molecule-only technology. The focus of this dissertation work has been on developing a class of hybrid silicon-molecular electronic devices for DRAM and Flash memory applications utilizing redox-active molecules. This work exploits the ability of molecules to store charges with single-electron precision at room temperature. The hybrid devices are fabricated by forming self-assembled monolayers of redox-active molecules on Si and oxide (SiO2 and HfO2) surfaces via formation of covalent linkages. The molecules possess discrete quantum states from which electrons can tunnel to the Si substrate at discrete applied voltages (oxidation process, cell write), leaving behind a positively charged layer of molecules. The reduction (erase) process, which is the process of electrons tunneling back from Si to the molecules, neutralizes the positively charged molecular monolayer. Hybrid silicon-molecular capacitor test structures were electrically characterized with an electrolyte gate using cyclic voltammetry (CyV) and impedance spectroscopy (CV) techniques. The redox voltages, kinetics (write/erase speeds) and charge-retention characteristics were found to be strongly dependent on the Si doping type and densities, and ambient light. It was also determined that the redox energy states in the molecules communicate with the valence band of the Si substrate. This allows tuning of write and read states by modulating minority carriers in n- and p-Si substrates. Ultra-thin dielectric tunnel barriers (SiO2, HfO2) were placed between the molecules and the Si substrate to augment charge-retention for Flash memory applications. The redox response was

  5. Optimal control, investment and utilization schemes for energy storage under uncertainty

    Science.gov (United States)

    Mirhosseini, Niloufar Sadat

    Energy storage has the potential to offer new means for added flexibility on the electricity systems. This flexibility can be used in a number of ways, including adding value towards asset management, power quality and reliability, integration of renewable resources and energy bill savings for the end users. However, uncertainty about system states and volatility in system dynamics can complicate the question of when to invest in energy storage and how best to manage and utilize it. This work proposes models to address different problems associated with energy storage within a microgrid, including optimal control, investment, and utilization. Electric load, renewable resources output, storage technology cost and electricity day-ahead and spot prices are the factors that bring uncertainty to the problem. A number of analytical methodologies have been adopted to develop the aforementioned models. Model Predictive Control and discretized dynamic programming, along with a new decomposition algorithm are used to develop optimal control schemes for energy storage for two different levels of renewable penetration. Real option theory and Monte Carlo simulation, coupled with an optimal control approach, are used to obtain optimal incremental investment decisions, considering multiple sources of uncertainty. Two stage stochastic programming is used to develop a novel and holistic methodology, including utilization of energy storage within a microgrid, in order to optimally interact with energy market. Energy storage can contribute in terms of value generation and risk reduction for the microgrid. The integration of the models developed here are the basis for a framework which extends from long term investments in storage capacity to short term operational control (charge/discharge) of storage within a microgrid. In particular, the following practical goals are achieved: (i) optimal investment on storage capacity over time to maximize savings during normal and emergency

    The goal of this study was to examine the adult surgical emergencies seen at the Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, with a view to proffering preventive solutions where appropriate and improving outcome. From the register of patients seen at the Casualty department and from the operations register in the main operation room of NAUTH, names and hospital numbers of adult patients treated as emergencies over a 5-year period, from 7 September 1998 to 6 September 2003, were obtained. The hospital folders were then retrieved from the Records Department. From each folder, the following details about each patient were extracted: age, sex, diagnosis at presentation, causative factors, treatment given, and outcome. A total of 902 adult patients were treated during the period. The commonest emergency operation was appendectomy for acute appendicitis in 139 patients (97 women and 42 men), followed closely by road traffic accidents (RTAs) involving 137 patients (103 men and 34 women). Gunshot injuries, which resulted mainly from armed robbery attacks, accounted for 127 cases. More men (113) sustained gunshot injuries than women (14). Of the 92 cases of acute intestinal obstruction seen, 62 occurred in women and 30 in men. Some 126 men presented with acute urinary retention, and two others presented with priapism. Governments at various levels should provide modern diagnostic tools for the accurate preoperative diagnosis of surgical emergencies in hospitals. Governments should also inculcate strict discipline into drivers using the highways, particularly in relation to abuse of alcohol and drugs. Good roads and adequate security should be provided for the people. The need for Pre-Hospital Care for the efficient evacuation of accident victims is emphasized. These measures will help to improve the management and outcome of surgical emergencies, and decrease the number of surgical emergencies resulting from RTAs and gunshot wounds.

    Full Text Available Objective: In Nigeria the rate of contraceptive use among sexually active adolescents is about 30%, considerably lower than the rates reported for developed countries. This study aimed to determine the knowledge, perception and practice of emergency contraception among female adolescent hawkers in Rigasa community, a suburb of Kaduna town.Materials and Methods: A cross sectional descriptive study of 1200 adolescent female hawkers aged 15–29 years was carried out in 2008, using both self and interviewer administered questionnaires. Results: Vast majority of the respondents are divorcees, constituting 92%. About 46% of them have never attended formal school before marriage. Of the 18 participants who were aware of emergency contraception; none correctly identified 72 hours as the time limit for the method’s use. Antibiotics or home remedies such as dye Robin Blue mixed with Coca cola or mixed with lime or lime mixed with potash and salt water were mentioned as unlisted methods of emergency contraception by responders. Conclusion: It is glaring that there exist a yawning gap of information and knowledge on contraception in general and emergency contraception in particular among female adolescent hawkers. The need to inform this target group about reproductive health generally and unwanted pregnancy in particular would not be out of place.

    A system for converting solar energy to chemical energy, and, subsequently, to thermal energy includes a light-harvesting station, a storage station, and a thermal energy release station. The system may include additional stations for converting the released thermal energy to other energy forms, e.g., to electrical energy and mechanical work. At the light-harvesting station, a photochemically active first organometallic compound, e.g., a fulvalenyl diruthenium complex, is exposed to light and is photochemically converted to a second, higher-energy organometallic compound, which is then transported to a storage station. At the storage station, the high-energy organometallic compound is stored for a desired time and/or is transported to a desired location for thermal energy release. At the thermal energy release station, the high-energy organometallic compound is catalytically converted back to the photochemically active organometallic compound by an exothermic process, while the released thermal energy is captured for subsequent use.

    Full Text Available Abstract Background Maternal mortality in Sub-Saharan Africa remains a challenge with estimates exceeding 1,000 maternal deaths per 100,000 live births in some countries. Successful prevention of maternal deaths hinges on adequate and quality emergency obstetric care. In addition to skilled personnel, there is need for a supportive environment in terms of essential drugs and supplies, equipment, and a referral system. Many household surveys report a reasonably high proportion of women delivering in health facilities. However, the quality and adequacy of facilities and personnel are often not assessed. The three delay model; 1 delay in making the decision to seek care; 2 delay in reaching an appropriate obstetric facility; and 3 delay in receiving appropriate care once at the facility guided this project. This paper examines aspects of the third delay by assessing quality of emergency obstetric care in terms of staffing, skills equipment and supplies. Methods We used data from a survey of 25 maternity health facilities within or near two slums in Nairobi that were mentioned by women in a household survey as places that they delivered. Ethical clearance was obtained from the Kenya Medical Research Institute. Permission was also sought from the Ministry of Health and the Medical Officer of Health. Data collection included interviews with the staff in-charge of maternity wards using structured questionnaires. We collected information on staffing levels, obstetric procedures performed, availability of equipment and supplies, referral system and health management information system. Results Out of the 25 health facilities, only two met the criteria for comprehensive emergency obstetric care (both located outside the two slums while the others provided less than basic emergency obstetric care. Lack of obstetric skills, equipment, and supplies hamper many facilities from providing lifesaving emergency obstetric procedures. Accurate estimation of burden

    Full Text Available Wakefields and beam instabilities are important issues for a storage ring and are described by various theoretical formalisms. Direct measurements of the beam motion related to different dynamical mechanisms are a useful input to accelerator optimization. This paper reports on an experimental method based on a simplified wakefield model, where bunch-by-bunch position information were monitored during the transient injection process at the Shanghai Synchrotron Radiation Facility. Processing the bunch-by-bunch data by means of the principal component analysis allowed for immediate operational improvements—such as in situ compensation of the kicker leakage, and energy matching between the booster and the storage ring.

T8 was used as the control treatment. Temperature and relative humidity of the environment was monitored, the roots were weighed monthly to access the weight loss, sprouting and rot were observed visually and proximate composition of the stored roots were evaluated using standard methods. The lowest percentage weight loss was observed in samples stored in a pit covered with wood ash and those covered with river sand. Samples stored in pits and covered with wood shavings, wood ash and river sand had the lowest percentage of sprouting (1.63%, 3.45% and 6.06% respectively. The dry matter content increased with storage period in all the storage methods. The starch yield varied in the different storage methods with the samplescovered with river sand (13.45% and the samples buried underground in the field(10.53% giving the highest starch yield at the end of the storage period.

    Corynespora cassiicola is a ubiquitous fungus causing emerging plant diseases worldwide, including target spot of cotton, soybean, and tomato, which have rapidly increased in incidence and severity throughout the southeastern United States. The objectives of this study were to understand the causes for the emerging target spot epidemics in the U.S. by comparing phylogenetic relationships of isolates from cotton, tomato, soybean, and other crop plants and ornamental hosts, and through the determination of the host range of isolates from emerging populations. Fifty-three isolates were sampled from plants in the southeastern U.S. and 1,380 nucleotides from four nuclear loci were sequenced. Additionally, sequences of the same loci from twenty-three isolates representing each of the distinct lineages of C. cassiicola described from previous studies were included. Isolates clustered based on host of origin, irrespective of the geographic location of sampling. There was no genetic diversity detected among isolates from cotton, which were genetically distinct from isolates from other host species. Furthermore, pathogenicity and virulence assays of 40 isolates from various hosts onto cotton, soybean, tomato, and cucumber showed that isolates from cotton were more aggressive to cotton than those from other hosts. Soybean and tomato were most susceptible to isolates that originated from the same host, providing evidence of host specialization. These results suggest that emerging target spot epidemics in the U.S. are caused by either the introduction of host-specific isolates or the evolution of more aggressive lineages on each host.

    In the days following a disaster/public health emergency, there is great effort to ensure that everyone receives appropriate care and lives are saved. However, evacuees following a disaster/public health emergency often lack access to personal health information that is vital to receive or maintain quality care. Delayed treatment and interruptions of medication regimens often contribute to excess morbidity and mortality following a disaster/public health emergency. This study sought to define a set of minimum health information elements that can be maintained in a personal health record (PHR) and given to first responders/receivers within the first 96 hours of a disaster/public health response to improve clinical health outcomes. A mixed methods approach of qualitative and quantitative data gathering and analyses was completed. Expert panel members (n = 116) and existing health information elements were sampled for this study; 55% (n = 64) of expert panel members had clinical credentials and determined the health information. From an initial set of 6 sources, a step-wise process using a Likert scale survey and thematic data analyses, including interrater reliability and validity checks, produced a set of minimum health information elements. The results identified 30 essential elements from 676 existing health information elements, a reduction of approximately 95%. The elements were grouped into 7 domains: identification, emergency contact, health care contact, health profile -past medical history, medication, major allergies/diet restrictions, and family information. Leading experts in clinical disaster preparedness identified a set of minimum health information elements that first responders/receivers must have to ensure appropriate and timely care. If this set of elements is used as the fundamental information for a PHR, and automatically updated and validated during clinical encounters and medication changes, it is conceivable that following large

    To examine urban-rural differences in US prevalences of traditional and emerging tobacco product use as well as dual or polytobacco use of these products. Our data were derived from wave 1 (2013-2014) of the Population Assessment of Tobacco and Health (PATH) Study. We estimated weighted prevalences of adult tobacco use across urban-rural geographies and examined prevalences classified by gender, poverty level, and region of the country. Nationally, cigarette use and smokeless tobacco use, as well as dual or polytobacco use of traditional products, were more prevalent in rural than in urban areas. Conversely, cigarillo and hookah use and dual or polytobacco use of emerging products were higher in urban areas. There was no significant urban-rural difference in use of e-cigarettes. Gender, poverty, and region of the country did not seem to be driving most urban-rural differences, although differences related to cigarillo use and dual or polytobacco use of emerging products became nonsignificant after control for covariates. Our findings highlight important urban-rural differences in tobacco use. Whether the changing tobacco product landscape will contribute to a continuation of rural health disparities remains to be seen.

    Anne C Spaulding

    Full Text Available Emergency departments and jails provide medical services to persons at risk for HIV infection and are recommended venues for HIV screening. Our main objective in this study was to analyze the cost per new HIV diagnosis associated with the HIV screening program in these two venues. The emergency department's parallel testing program was conducted at Grady Memorial Hospital in Atlanta, Georgia starting in 2008; the jail's integrated testing program began at the Fulton County (GA Jail in 2011. The two sites, four miles apart from one another, employed the same rapid HIV test. Ascertainment that cases were new differed by site; only the jail systematically checked identities against health department HIV registries. The program in the emergency department used dedicated HIV test counselors and made 242 diagnoses over a 40-month period at a cost of $2,981 per diagnosis. The jail program used staff nurses, and found 41 new HIV cases over 10.5 months at a cost of $6,688 per new diagnosis. Differences in methods for ascertainment of new diagnoses, previously undiagnosed HIV sero-positivity, and methodologies used for assessing program costs prevent concluding that one program was more economical than the other. Nonetheless, our findings show that testing in both venues yielded many new diagnoses, with the costs within the range reported in the literature.

We investigate the effect of various kinds of two-body interlayer couplings on the (330) bilayer state and exactly solve the Hamiltonian for up to 14 electrons on sphere and torus geometries. We consider interlayer tunneling, short-ranged repulsive/attractive pseudopotential interactions, and Coulomb repulsion. We find a 6-fold ground-state degeneracy on the torus when the interlayer hollow-core interaction is dominant. To identify the topological nature of this phase we measure the orbital-cut entanglement spectrum, quasihole counting, topological entanglement entropy, and wave-function overlap. Comparing the numerical results to the theoretical predictions, we interpret this 6-fold ground-state degeneracy phase to be the non-Abelian bilayer Fibonacci state.

  9. 21st Century California Water Storage Strategies

    Full Text Available https://doi.org/10.15447/sfews.2017v15iss4art1The goal of this paper is to analyze storage projects constructed and planned in California since 1980, in contrast with storage constructed before that date. As a result of California’s highly variable climate, storage is an essential tool for agricultural and urban water users. Today, the state regulates approximately 1,250 reservoirs, with a combined storage of 42 million acre-feet. Federal agencies regulate approximately 200 additional reservoirs. The vast majority of this surface storage was constructed before 1978, when New Melones Dam, the last large on-stream water supply reservoir in California, was completed. The role of storage in meeting future needs remains a high-profile issue in the California water debate. For example, funding for new storage was the largest item in Proposition 1, the most recent water bond voters approved. This analysis included a review of existing literature, such as the California Department of Water Resources Division of Dam Safety database, California Water Commission documents about new storage proposals, water agency documents, and interviews with water agency staff and others. Water managers face dramatically different conditions today, in comparison to conditions before 1980. These conditions have led to new approaches to water storage that represent a dramatic departure from past storage projects. During the past 37 years, a wide range of new water storage strategies have been planned and implemented. These facilities have created a combined new storage capacity greater than that of Lake Shasta, California’s largest reservoir. These new storage strategies suggest the need to revisit the fundamental definition of water storage. With limited potential for new storage drawing from the state’s rivers, California must choose storage projects wisely. By learning from successful strategies in recent decades, decision-makers can make better storage investment

    We argue that the modified Landau-Raychaudhuri equations should first be analysed in a large class of spacetimes and in dependence on various equations of states, before endorsing any conclusion about (non)singular Big Bang. From the corrected entropy-area law in a large class of metrics, the generalized uncertainty principle (GUP) and the modified dispersion relation (MDR) approaches, and various equations of states, the modified Friedmann equations are derived. They are applied on Landau-Raychaudhuri equations in emergence of cosmic space framework from fixed point method. We show that any conclusion about (non)singular Big Bang is simply badly model-dependent, especially when utilizing GUP and MDR approaches, which can not replace a good theory for quantum gravity. We conclude that the various quantum gravity approaches, metrics and equations of state lead to different modifications in Friedmann and Landau-Raychaudhuri equations and thus to different (non)singular solutions for Big Bang theory.

    Implementation and adoption of efficient end-use technologies have proven to be one of the key measures for reducing greenhouse gas (GHG) emissions throughout the industries. In many cases, implementing energy efficiency measures is among one of the most cost effective investments that the industry could make in improving efficiency and productivity while reducing CO2 emissions. Over the years, there have been incentives to use resources and energy in a cleaner and more efficient way to create industries that are sustainable and more productive. With the working of energy programs and policies on GHG inventory and regulation, understanding and managing the costs associated with mitigation measures for GHG reductions is very important for the industry and policy makers around the world. Successful implementation of emerging technologies not only can help advance productivities and competitiveness but also can play a significant role in mitigation efforts by saving energy. Providing evaluation and estimation of the costs and energy savings potential of emerging technologies is the focus of our work in this project. The overall goal of the project is to identify and select emerging and under-utilized energy-efficient technologies and practices as they are important to reduce energy consumption in industry while maintaining economic growth. This report contains the results from performing Task 2"Technology evaluation" for the project titled"Research Opportunities in Emerging and Under-Utilized Energy-Efficient Industrial Technologies," which was sponsored by California Energy Commission and managed by CIEE. The project purpose is to analyze market status, market potential, and economic viability of selected technologies applicable to the U.S. In this report, LBNL first performed re-assessments of all of the 33 emerging energy-efficient industrial technologies, including re-evaluation of the 26 technologies that were previously identified by Martin et al. (2000) and

    Migraine is often perceived as a low-impact condition that imposes a limited burden to society and the health-care system. This study reviews the current understanding of the burden of migraine in the U.S., the history of economic understanding of migraine treatment and identifies emergent trends for future studies evaluating clinical and economic outcomes of migraine treatment. This study traced the history of economic articles published on migraine by performing a literature search using PubMed MEDLINE database and ancestral searches of relevant articles. The intention was not to provide an exhaustive review of every article or adjudicate between studies with different findings. Migraine affects millions of individuals worldwide, generally during the most productive years of a person's life. Studies show that migraineurs are underdiagnosed, undertreated, and experience substantial decreases in functioning and productivity, which in turn translates into diminished quality of life for individuals, and financial burdens to both health-care systems and employers. Economic evaluations of migraine therapies have evolved with new clinical developments beginning with cognitive-behavioral therapy, introduction of triptans, concern over medication overuse, and emergence of migraine prophylaxis. Now recent clinical studies suggest that migraine may be a progressive disease with cardiovascular, cerebrovascular, and long-term neurologic effects. Migraine imposes a substantial burden on patients, families, employers and societies. The economic standards by which migraine and treatment are evaluated have evolved in response to clinical developments. Emerging evidence suggests that migraine is a chronic and progressive disease. If confirmed, approaches to acute and prophylactic treatments and economic evaluations of migraine treatment may require major reconsideration.

    Full Text Available http://dx.doi.org/10.5902/1980509810541 The seed germination strategy is important for the survival of species, allowing their maintenance and regeneration in the environment. Seed germination and seedling emergence of Anadenanthera colubrina were studied to examine the reproductive efficiency of this species, typical of Cerrado biome. The fruits were collected in ‘Vale do Rio Araguari’, in MG state. The water content at 105 °C, the germination in controlled laboratory conditions and seedling emergence in semi-open greenhouse were analyzed. The seeds had low water content between 6.7 to 10.7%. The germinating ability and the emergence percentage were high for almost all studied individuals, being registered 68 for seeds of individual number 2 and 85 - 94% for the others; 38% (individual number 2 and 78 - 91% (for the others, respectively. The speed of the processes was high, with the end of germination within 12.8 days and emergence within 18.8 days. The processes were heterogeneous, with values of coefficient of variation of the germination or emergence time above 28.5%; asynchronous, with values of uncertainty above 1.5 bits and synchrony below 0.3812. The seeds of this species were efficient in both processes and the heterogeneity and asynchrony may indicate the effects of environmental fluctuations during the seed formation, besides the genetic variability, intrinsic to each individual of the population. The speed and the high potential of seed germination of this species may also facilitate the programs of reforestation with the production of large numbers of seedlings in short time.

    To characterize the current scope and practices of centers performing extracorporeal cardiopulmonary resuscitation (eCPR) on the undifferentiated patient with cardiac arrest in the emergency department. We contacted all US centers in January 2016 that had submitted adult eCPR cases to the Extracorporeal Life Support Organization (ELSO) registry and surveyed them, querying for programs that had performed eCPR in the Emergency Department (ED ECMO). Our objective was to characterize the following domains of ED ECMO practice: program characteristics, patient selection, devices and techniques, and personnel. Among 99 centers queried, 70 responded. Among these, 36 centers performed ED ECMO. Nearly 93% of programs are based at academic/teaching hospitals. 65% of programs are less than 5 years old, and 60% of programs perform ≤3 cases per year. Most programs (90%) had inpatient eCPR or salvage ECMO programs prior to starting ED ECMO programs. The majority of programs do not have formal inclusion and exclusion criteria. Most programs preferentially obtain vascular access via the percutaneous route (70%) and many (40%) use mechanical CPR during cannulation. The most commonly used console is the Maquet Rotaflow(®). Cannulation is most often performed by cardiothoracic (CT) surgery, and nearly all programs (>85%) involve CT surgeons, perfusionists, and pharmacists. Over a third of centers that submitted adult eCPR cases to ELSO have performed ED ECMO. These programs are largely based at academic hospitals, new, and have low volumes. They do not have many formal inclusion or exclusion criteria, and devices and techniques are variable. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    2015-03-01

    Full Text Available Purpose: to determine the motivation of employees of structural subdivisions of the State Emergency Service of Ukraine to improve their level of professional competence by means of physical training. Material: questionnaire survey of 130 rescue workers aged 25 to 40 years. Results: the main motives of rescue team personnel for physical culture and sports activities are gain in physical health and professional competence, while performing rescue missions. It was established that, when on duty, most of the firefighters and rescue workers are not engaged in physical exercise at all; household chores and poor state of health in case of men prevent rescue team employees from doing exercises outside of working hours. It was found that fire-rescue specialists give preference to the development of muscle strength during professional physical trainings and would like to perform power exercises. Conclusions: the low level of motivation of current fire-rescue workers for physical self-improvement requires optimization of control over professional physical education in departments of the State Emergency Service of Ukraine.

    The rock cavern storage for spent fuel has been assessed to apply in Korea with reviewing the state of the art of the technologies for surface storage and rock cavern storage of spent fuel. The technical feasibility and economic aspects of the rock cavern storage of spent fuel were also analyzed. A considerable area of flat land isolated from the exterior are needed to meet the requirement for the site of the surface storage facilities. It may, however, not be easy to secure such areas in the mountainous region of Korea. Instead, the spent fuel storage facilities constructed in the rock cavern moderate their demands for the suitable site. As a result, the rock cavern storage is a promising alternative for the storage of spent fuel in the aspect of natural and social environments. The rock cavern storage of spent fuel has several advantages compared with the surface storage, and there is no significant difference on the viewpoint of economy between the two alternatives. In addition, no great technical difficulties are present to apply the rock cavern storage technologies to the storage of domestic spent fuel.

    The report contains an overall frame for transformation of knowledge and experience from risk analysis to emergency education. An accident model has been developed to describe the emergency situation. A key concept of this model is uncontrolled flow of energy (UFOE), essential elements are the state, location and movement of the energy (and mass). A UFOE can be considered as the driving force of an accident, e.g., an explosion, a fire, a release of heavy gases. As long as the energy is confined, i.e. the location and movement of the energy are under control, the situation is safe, but loss of confinement will create a hazardous situation that may develop into an accident. A domain model has been developed for representing accident and emergency scenarios occurring in society. The domain model uses three main categories: status, context and objectives. A domain is a group of activities with allied goals and elements and ten specific domains have been investigated: process plant, storage, nuclear power plant, energy distribution, marine transport of goods, marine transport of people, aviation, transport by road, transport by rail and natural disasters. Totally 25 accident cases were consulted and information was extracted for filling into the schematic representations with two to four cases pr. specific domain. (au) 41 tabs., 8 ills.; 79 refs.

    To examine the trend of concussions in skiers and snowboarders from 2010 to 2014; and to quantify and compare the incidence of concussions injuries in skiers and snowboarders who presented to emergency departments in the United States in 2014. Cross-sectional study of concussions in skiers and snowboarders who were evaluated in emergency departments in the United States. Incidence of concussions. The trend of the annual incidence of concussions for skiers and snowboarders remained stable from 2010 to 2014. An estimated total of 5388 skiing-related concussions and 5558 snowboarding-related concussions presented to emergency departments in the United States between January 1st, 2014, and December 31st, 2014. This represented an incidence of 16.9 concussions per 1 000 000 person-years for skiers and 17.4 concussions per 1 000 000 person-years for snowboarders. The incidence of concussions in the pediatric and young adult population of skiers was significantly higher than the incidence in the adult population. Similarly, the incidence of concussions in the pediatric and young adult population of snowboarders was significantly higher than the incidence in the adult population. The incidence of concussions was significantly higher in males compared with females in both skiing and snowboarding. The incidence of concussions from 2010 to 2014 plateaued in both skiers and snowboarders. Pediatric and young adult skiers and snowboarders had significantly higher incidences of concussion than the adult population. In contrast to the higher incidence of concussions in females in several sports including ice hockey, soccer, and basketball, the incidence of concussions was higher in males compared with females in both skiing and snowboarding.

  3. Mother and Infant Talk about Mental States: Systemic Emergence of Psychological Lexicon and Theory of Mind Understanding

    Science.gov (United States)

    Rollo, D.; Buttiglieri, F.

    In recent years, a number of studies that have examined how social experiences are related to children's theory of mind development, have found that: (1) the frequency of mothers' mental state utterances used in mother-child picture-book reading, is correlated with children's theory of mind abilities; (2) mothers' use of cognitive terms is related more strongly to children's theory of mind performances than the mothers' references to other mental states, such as desires or emotions (Adrian, Clemente, Villanueva, Rieffe, 2005; Ruffman, Slade, Crowe, 2002; Taumoepeau, Ruffman, 2006; Dunn, 2002). Despite the evidence for the role of mothers' language, there is disagreement over how exactly it improves children's theory of mind development. In short, mentalistic comments contain distinctive words, grammatical constructions and pragmatic features. The question is, however, which factor is critical (de Rosnay, Pons, Harris, Morrell, 2004). The present study addresses this issue and focuses on relationship between mothers' mental state terms and children's performances in theory of mind tasks (emotion understanding and false belief tasks). Mothers were asked to read some pictures to 10 children between 3;0 and 5;0. Among the different mental state references (perceptual, emotional, volitional, cognitive, moral and communicative), it was found that the frequency and variety of mothers' mental state words were significantly associated with children's mental lexicon. In addition, emotional terms correlated positively with children's false belief performance. Kind of emotional words that are used by the mothers with reference to the Italian language will be discussed.

    Full Text Available Concern about increasing atmospheric concentrations of carbon dioxide (CO2 and other greenhouse gases (GHG and their impact on the earth's climate has grown significantly over the last decade. Many countries, including the United States, wrestle with balancing economic development and meeting critical near-term environmental goals while minimizing long-term environmental risks. One promising solution to the buildup of GHGs in the atmosphere, being pursued by the U.S. Department of Energy's (DOE National Energy Technology Laboratory (NETL and its industrial and academic partners, is carbon sequestration—a process of permanent storage of CO2 emissions in underground geologic formations, thus avoiding CO2 release to the atmosphere. This option looks particularly attractive for point source emissions of GHGs, such as fossil fuel fired power plants. CO2 would be captured, transported to a sequestration site, and injected into an appropriate geologic formation. However, sequestration in geologic formations cannot achieve a significant role in reducing GHG emissions unless it is acceptable to stakeholders, regulators, and the general public, i.e., unless the risks involved are judged to be acceptable. One tool that can be used to achieve acceptance of geologic sequestration of CO2 is risk assessment, which is a proven method to objectively manage hazards in facilities such as oil and natural gas fields, pipelines, refineries, and chemical plants. Although probabilistic risk assessment (PRA has been applied in many areas, its application to geologic CO2 sequestration is still in its infancy. The most significant risk from geologic carbon sequestration is leakage of CO2. Two types of CO2 releases are possible—atmospheric and subsurface. High concentrations of CO2 caused by a release to the atmosphere would pose health risks to humans and animals, and any leakage of CO2 back into the atmosphere negates the effort expended to sequester the CO2

    Full Text Available Turkey's role as a regional power has increased since Justice and Development Party (AKP came to power. AKP leadership not only aspired to become a regional power but also a global player. Turkey has, therefore, assumed different roles: the "natural leader" of the region; a historical "big brother;" and the "protector" of the Muslim minorities. Turkey has also assumed a "mediator" and a "facilitator" role by trying to negotiate a deal with an emerging power such as Brazil in order to attempt to resolve the controversial Iranian nuclear issue. By making use of recent developments, Turkey tried to solidify its long desired role as a "rising power" by increasing its influence in its neighborhood and engaging with other emerging powers. The concept "regional power" is a context-based notion. In other words, the location and geography are contesting and disputed approaches. Notwithstanding the fact that concepts such as "region" and "power" are social constructed reality, this paper analyzes the notion of 'regional power' as a subcategory of 'power'. In this context, this paper will make use of Stefan Schim's criteria while analyzing Turkey's power capacity in the region. Schim posits that the "regional power" needs to have a "role definition," and it should possess material power (hard power. It should also have economic as well as diplomatic and organizational capacity. Its power whether it is 'soft power' (attraction of ones idea's and or the ability to set the political agenda in a way that shapes the preferences of other actors or 'hard power' (material power that can be measured-economic and military power needs to be acknowledged by other actors in the region. It should also be accepted by great powers and emerging powers that are determinant in the international system. dditionally, the regional power (and/ or global power needs to have leverage, thus its power projection needs to yield results.

    The slow pace of Pumped Storage Hydropower development in the US over the past twenty years has led to widespread interest in the feasibility and viability of alternative PSH designs, development schemes, and technologies. Since 2011, Oak Ridge National Lab has been exploring the economic viability of modular Pumped Storage Hydropower (m-PSH) development through targeted case studies, revenue simulations, and analysis of innovative configurations and designs. This paper outlines the development and supporting analysis of a scalable, comprehensive cost modeling tool designed to simulate the initial capital costs for a variety of potential m-PSH projects and deployment scenarios. The tool is used to explore and determine innovative research strategies that can improve the economic viability of m-PSH in US markets.

    Present and future relatively small (30 MW) energy systems, such as solar thermal electric, photovoltaic, wind, fuel cell, storage battery, hydro, and cogeneration can help achieve national energy goals and can be dispersed throughout the distribution portion of an electric utility system. Based on current projections, it appears that dispersed storage and generation (DSG) electrical energy will comprise only a small portion, from 4 to 10 percent, of the national total by the end of this century. In general, the growth potential for DSG seems favorable in the long term because of finite fossil energy resources and increasing fuel prices. Recent trends, especially in the institutional and regulatory fields, favor greater use of the DSGs for the future.

    In past work, Berkeley Lab has developed the Distributed Energy Resources Customer Adoption Model (DER-CAM). Given end-use energy details for a facility, a description of its economic environment and a menu of available equipment, DER-CAM finds the optimal investment portfolio and its operating schedule which together minimize the cost of meeting site service, e.g., cooling, heating, requirements. Past studies have considered combined heat and power (CHP) technologies. Methods and software have been developed to solve this problem, finding optimal solutions which take simultaneity into account. This project aims to extend on those prior capabilities in two key dimensions. In this research storage technologies have been added as well as power quality and reliability (PQR) features that provide the ability to value the additional indirect reliability benefit derived from Consortium for Electricity Reliability Technology Solutions (CERTS) Microgrid capability. This project is intended to determine how attractive on-site generation becomes to a medium-sized commercial site if economical storage (both electrical and thermal), CHP opportunities, and PQR benefits are provided in addition to avoiding electricity purchases. On-site electrical storage, generators, and the ability to seamlessly connect and disconnect from utility service would provide the facility with ride-through capability for minor grid disturbances. Three building types in both California and New York are assumed to have a share of their sensitive electrical load separable. Providing enhanced service to this load fraction has an unknown value to the facility, which is estimated analytically. In summary, this project began with 3 major goals: (1) to conduct detailed analysis to find the optimal equipment combination for microgrids at a few promising commercial building hosts in the two favorable markets of California and New York; (2) to extend the analysis capability of DER-CAM to include both heat and

    Background We aimed to characterize patterns in the timing of initial emergency procedures for patients with open tibia fracture and examine the relationship between initial procedure timing and in-hospital amputation. Study Design Data were analyzed from the Nationwide Inpatient Sample, 2003–2009. Adult patients were included if they had a primary diagnosis code of open tibia fracture. Patients were excluded for the following: transferred from or to another hospital, an immediate amputation was performed, more than one amputation was performed, no emergency procedure was documented, or treated at a facility that did not perform any amputations. We evaluated the association between timing of the first procedure and the outcome of amputation using multiple logistic regression, controlled for patient risk factors and hospital characteristics. Results Of 7,560 patients included in the analysis, 1.3% (n=99 patients) underwent amputation on hospital day 2 or later. The majority of patients (52.6%) underwent first operative procedure on day 0 or 1. In adjusted analyses, timing of first operative procedure beyond the day of admission is associated with more than three times greater odds of amputation (day 1 OR 3.81, 95% CI 1.80–8.07). Conclusions Delay of first operative procedure beyond the day of admission appears to be associated with a significantly increased probability of amputation in patients with open tibia fracture. All practitioners involved in the management of patients with open tibia fracture should seek a solution for any barrier, other than medical stability of the patient, of achieving early operative intervention.

    Full Text Available In 2016, the European Union has launched a new and ambitious project for the future regulation of international trade in the European Union and the rules of its taxation: since the 1 May 2016, the new Union Customs Code (UCC has entered into force. It revokes the old Community Customs Code (CCC, which was applied since 1992, and passed in the form of EU regulation sets brand-new rules for the application of Common Customs Tariff and calculation of customs duties (tariffs in all the EU Member States. It is oriented to the creation of the paperless environment for the formalisation of international trade operations (full electronic declaration of customs procedures and ensuring of a more uniform administration of customs duties in the tax and customs authorities of the Member States in the European Union. Therefore, the article raises and seeks to answer the problematic question whether the Member States of the European Union themselves are ready to implement these ambitious goals and does the actual practice of the Member States support that (considering the practice of the Republic of Lithuania. The research, which is based on the analysis of case law in the Republic of Lithuania (case study of recent tax disputes between the taxpayers and customs authorities that arose immediately before and after the entry into force of the UCC, leads to the conclusion that many problematic areas that may negatively impact the functioning of the new Customs Code remain and must be improved, including an adoption of new legislative solutions.

    The author focused on recent national trends in dental emergency department (ED) visits. Patients who presented at an ED for a dental condition are described and the author look at the extent to which these patients have changed over time. This study was based on the National Ambulatory Medical Care Survey, a national probability survey of hospital ED visits. A dental ED visit was defined using International Classification of Diseases, Ninth Edition, Clinical Modification diagnostic codes. Between 1997/1998 and 2007/2008, dental ED visits increased from 1.15 to 1.87 percent of total ED visits. The largest increase in the number of dental ED visits per 1,000 persons was found for young adults 20-34 years old. Primary payer, a measure of insurance status, suggests that patients from all income levels participated in the increase. Although dental-related ED visits account for a relatively small percentage of total ED visits, both the number and the percentage of such visits grew from 1997/1998 to 2007/2008. Young adults 20-34 years old were most likely to present at an ED with a dental problem. © 2012 American Association of Public Health Dentistry.

    2015-09-03

    This paper (and its supplemental model) presents novel approaches to modeling interactions and related policies among investment, production, and learning in an emerging competitive industry. New biomass-to-biofuels pathways are being developed and commercialized to support goals for U.S. advanced biofuel use, such as those in the Energy Independence and Security Act of 2007. We explore the impact of learning rates and techno-economics in a learning model excerpted from the Biomass Scenario Model (BSM), developed by the U.S. Department of Energy and the National Renewable Energy Laboratory to explore the impact of biofuel policy on the evolution of the biofuels industry. The BSM integrates investment, production, and learning among competing biofuel conversion options that are at different stages of industrial development. We explain the novel methods used to simulate the impact of differing assumptions about mature industry techno-economics and about learning rates while accounting for the different maturity levels of various conversion pathways. A sensitivity study shows that the parameters studied (fixed capital investment, process yield, progress ratios, and pre-commercial investment) exhibit highly interactive effects, and the system, as modeled, tends toward market dominance of a single pathway due to competition and learning dynamics.

    Expanding access to office-based medication-assisted treatment with buprenorphine/naloxone for opioid dependence is a key part of the national strategy to address the opioid abuse epidemic (1). However, as buprenorphine/naloxone prescribing increased, emergency department (ED) visits and hospitalizations for unsupervised ingestions by young children began to increase, with buprenorphine/naloxone ingestions becoming the most common cause of hospitalization for medication ingestions by young children during 2010-2011 (2). Buprenorphine ingestions might be asymptomatic or can cause drowsiness, vomiting, or respiratory depression, which if untreated can result in death (3). Buprenorphine/naloxone was available only as tablets in multidose child-resistant bottles (Suboxone) until late 2010, when film strips packaged in unit-dose, child-resistant pouches were introduced. In 2013, tablets became available in unit-dose packaging (Zubsolv). Because unit-dose, child-resistant packaging encloses each dose until opened, it might limit unintended ingestions by young children compared with traditional child-resistant bottles that must be resecured after every use (4). This study compared ED visits for pediatric buprenorphine/naloxone ingestions before and after these product packaging/formulation changes.

    When chemical or microbial contaminants are assessed for potential effect or possible regulation in ambient and drinking waters, a critical first step is determining if the contaminants occur and if they are at concentrations that may cause human or ecological health concerns. To this end, source and treated drinking water samples from 29 drinking water treatment plants (DWTPs) were analyzed as part of a two-phase study to determine whether chemical and microbial constituents, many of which are considered contaminants of emerging concern, were detectable in the waters. Of the 84 chemicals monitored in the 9 Phase I DWTPs, 27 were detected at least once in the source water, and 21 were detected at least once in treated drinking water. In Phase II, which was a broader and more comprehensive assessment, 247 chemical and microbial analytes were measured in 25 DWTPs, with 148 detected at least once in the source water, and 121 detected at least once in the treated drinking water. The frequency of detection was often related to the analyte's contaminant class, as pharmaceuticals and anthropogenic waste indicators tended to be infrequently detected and more easily removed during treatment, while per and polyfluoroalkyl substances and inorganic constituents were both more frequently detected and, overall, more resistant to treatment. The data collected as part of this project will be used to help inform evaluation of unregulated contaminants in surface water, groundwater, and drinking water.

    Full Text Available Background. Finding a usual source of care (USC is difficult for certain populations. This analysis determines how insurance type and having a USC affect the settings in which patients seek care. Methods. In this cross-sectional study of the 2000–2011 Medical Expenditure Panel Surveys, we assessed the percentage of low-income persons with half or more of their ambulatory visits to the emergency department (ED. Respondents were stratified based on insurance type and presence of a USC. Results. In 2011, among Medicaid enrollees without USCs, 21.6% had half or more of their ambulatory visits to EDs compared to 8.1% for those with USCs. Among the uninsured without USCs, 24.1% went to an ED for half or more of their ambulatory visits compared to 8.8% for those with USCs in 2011. Among the privately insured without USCs, 7.8% went to an ED for half or more of their ambulatory visits compared to 5.0% for those with USCs in 2011. These differences remained in multivariate analyses. Conclusions. Those who lack USCs, particularly the uninsured and Medicaid enrollees, are more likely to rely on EDs.

    2018-01-16

    As part of the National Plan to Address Alzheimer's Disease, reducing potentially avoidable emergency department (ED) use by individuals with dementia has been identified as a component of enhancing the quality and efficiency of care for this population. To help inform the development of interventions to achieve this goal, an integrative review was conducted to: (a) compare rates and reasons for ED visits by community-dwelling individuals with and without dementia, considering also the effect of dementia subtype and severity; and (b) identify other risk factors for increased ED use among community-dwelling individuals with dementia. Nineteen articles met inclusion criteria. Individuals with dementia had higher rates of ED visits compared to those without dementia, although differences were attenuated in the last year of life. Increased symptoms and disability were associated with increased rates of ED visits, whereas resources that enabled effective management of increased need decreased rates. Gerontological nurses across settings are on the frontlines of preventing potentially avoidable ED visits by community-dwelling individuals with dementia through patient and family education and leadership in the development of new models of care.

    The EMS Energy Institute at The Pennsylvania State University (Penn State) has managed the Gas Storage Technology Consortium (GSTC) since its inception in 2003. The GSTC infrastructure provided a means to accomplish industry-driven research and development designed to enhance the operational flexibility and deliverability of the nation's gas storage system, and provide a cost-effective, safe, and reliable supply of natural gas to meet domestic demand. The GSTC received base funding from the U.S. Department of Energy's (DOE) National Energy Technology Laboratory (NETL) Oil & Natural Gas Supply Program. The GSTC base funds were highly leveraged with industry funding for individual projects. Since its inception, the GSTC has engaged 67 members. The GSTC membership base was diverse, coming from 19 states, the District of Columbia, and Canada. The membership was comprised of natural gas storage field operators, service companies, industry consultants, industry trade organizations, and academia. The GSTC organized and hosted a total of 18 meetings since 2003. Of these, 8 meetings were held to review, discuss, and select proposals submitted for funding consideration. The GSTC reviewed a total of 75 proposals and committed co-funding to support 31 industry-driven projects. The GSTC committed co-funding to 41.3% of the proposals that it received and reviewed. The 31 projects had a total project value of $6,203,071 of which the GSTC committed $3,205,978 in co-funding. The committed GSTC project funding represented an average program cost share of 51.7%. Project applicants provided an average program cost share of 48.3%. In addition to the GSTC co-funding, the consortium provided the domestic natural gas storage industry with a technology transfer and outreach infrastructure. The technology transfer and outreach were conducted by having project mentoring teams and a GSTC website, and by working closely with the Pipeline Research Council International (PRCI) to

    The aging of America poses a challenge to emergency departments (EDs). Studies show that elderly patients have poor outcomes despite increased testing, prolonged periods of observation, and higher admission rates. In response, emergency medicine (EM) leaders have implemented strategies for improved ED elder care, enhancing expertise, equipment, policies, and protocols. One example is the development of geriatric EDs gaining in popularity nationwide. To the authors' knowledge, this is the first research to systematically identify and qualitatively characterize the existence, locations, and features of geriatric EDs across the United States. The primary objective was to determine the number, distribution, and characteristics of geriatric EDs in the United States in 2013. This was a survey with potential respondents identified via a snowball sampling of known geriatric EDs, EM professional organizations' geriatric interest groups, and a structured search of the Internet using multiple search engines. Sites were contacted by telephone, and those confirming geriatric EDs presence received the survey via e-mail. Category questions included date of opening, location, volumes, staffing, physical plant changes, screening tools, policies, and protocols. Categories were reported based on general interest to those seeking to understand components of a geriatric ED. Thirty-six hospitals confirmed geriatric ED existence and received surveys. Thirty (83%) responded to the survey and confirmed presence or plans for geriatric EDs: 24 (80%) had existing geriatric EDs, and six (20%) were planning to open geriatric EDs by 2014. The majority of geriatric EDs are located in the Midwest (46%) and Northeast (30%) regions of the United States. Eighty percent serve from 5,000 to 20,000 elder patients annually. Seventy percent of geriatric EDs are attached to the main ED, and 66% have from one to 10 geriatric beds. Physical plant changes include modifications to beds (96%), lighting (90

    2015-10-02

    A large number of nonfatal injuries are treated in U.S. emergency departments (EDs) every year. CDC's National Center for Health Statistics estimates that approximately 29% of all ED visits in 2010 were for injuries. To assess the economic impact of ED-treated injuries, CDC examined injury data from the National Electronic Injury Surveillance System--All Injury Program (NEISS-AIP) for 2013, as well as injury-related lifetime medical and work-loss costs from the Web-Based Injury Statistics Query and Reporting System (WISQARS). NEISS-AIP collects data from a nationally representative sample of EDs, using specific guidelines for recording the primary diagnosis and mechanism of injury. Number of injuries, crude- and age-specific injury rates, and total lifetime work-loss costs and medical costs were calculated for ED-treated injuries, stratified by sex, age groups, and intent and mechanism of injury. ED-treated injuries were further classified as those that were subsequently hospitalized or treated and released. The rate of hospitalized injuries was 950.8 per 100,000, and the rate of treated and released injuries was 8,549.8 per 100,000. Combined medical and work-loss costs for all ED-treated injuries (both hospitalized and treated and released) were $456.9 billion, or approximately 68% of the total costs of $671 billion associated with all fatal and ED-treated injuries. The substantial economic burden associated with nonfatal injuries underscores the need for effective prevention strategies.

    Objective We determined the minimum mortality reduction that helicopter emergency medical services (HEMS) should provide relative to ground EMS for the scene transport of trauma victims to offset higher costs, inherent transport risks, and inevitable overtriage of minor injury patients. Methods We developed a decision-analytic model to compare the costs and outcomes of helicopter versus ground EMS transport to a trauma center from a societal perspective over a patient's lifetime. We determined the mortality reduction needed to make helicopter transport cost less than $100,000 and $50,000 per quality adjusted life year (QALY) gained compared to ground EMS. Model inputs were derived from the National Study on the Costs and Outcomes of Trauma (NSCOT), National Trauma Data Bank, Medicare reimbursements, and literature. We assessed robustness with probabilistic sensitivity analyses. Results HEMS must provide a minimum of a 17% relative risk reduction in mortality (1.6 lives saved/100 patients with the mean characteristics of the NSCOT cohort) to cost less than $100,000 per QALY gained and a reduction of at least 33% (3.7 lives saved/100 patients) to cost less than $50,000 per QALY. HEMS becomes more cost-effective with significant reductions in minor injury patients triaged to air transport or if long-term disability outcomes are improved. Conclusions HEMS needs to provide at least a 17% mortality reduction or a measurable improvement in long-term disability to compare favorably to other interventions considered cost-effective. Given current evidence, it is not clear that HEMS achieves this mortality or disability reduction. Reducing overtriage of minor injury patients to HEMS would improve its cost-effectiveness.

    2012-08-01

    Adaptive wear-resistant coatings produced by physical vapor deposition (PVD) are a relatively new generation of coatings which are attracting attention in the development of nanostructured materials for extreme tribological applications. An excellent example of such extreme operating conditions is high performance machining of hard-to-cut materials. The adaptive characteristics of such coatings develop fully during interaction with the severe environment. Modern adaptive coatings could be regarded as hierarchical surface-engineered nanostructural materials. They exhibit dynamic hierarchy on two major structural scales: (a) nanoscale surface layers of protective tribofilms generated during friction and (b) an underlying nano/microscaled layer. The tribofilms are responsible for some critical nanoscale effects that strongly impact the wear resistance of adaptive coatings. A new direction in nanomaterial research is discussed: compositional and microstructural optimization of the dynamically regenerating nanoscaled tribofilms on the surface of the adaptive coatings during friction. In this review we demonstrate the correlation between the microstructure, physical, chemical and micromechanical properties of hard coatings in their dynamic interaction (adaptation) with environment and the involvement of complex natural processes associated with self-organization during friction. Major physical, chemical and mechanical characteristics of the adaptive coating, which play a significant role in its operating properties, such as enhanced mass transfer, and the ability of the layer to provide dissipation and accumulation of frictional energy during operation are presented as well. Strategies for adaptive nanostructural coating design that enhance beneficial natural processes are outlined. The coatings exhibit emergent behavior during operation when their improved features work as a whole. In this way, as higher-ordered systems, they achieve multifunctionality and high wear

    The Government of Kazakhstan is engaged in a "root and branch" modernisation of the health care sector. One aspect of the raft of modernisation programmes was to revisit the State Guaranteed Health Benefits Package, with the aim to review citizen entitlements to healthcare. This paper reviews the ongoing evolution of the planning of the health benefits package in Kazakhstan, with the main challenges encountered, and critical lessons learned, to be considered for similar attempts elsewhere. The main conclusions are that: the design process requires a blend of technical and socio-political analysis, because it attracts public interest, and therefore political risks; the scale and burden of analysis need to be kept to manageable proportions; and the relationship between the benefits package and funding modalities needs to be carefully managed by the State, to ensure access to declared entitlements to all members, including the most vulnerable, while keeping the package financially feasible. © 2017 The Authors.

    Background: Visceral leishmaniasis (VL) is an emerging zoonosis, and Brazil harbors about 90% of those infected in Latin America. Since 1998, the disease has been spreading quickly in São Paulo state, and the western region is considered an emerging focus of VL in Brazil. Our aim was to evaluate the clinical characteristics and spatial distribution of VL in children referred to a public tertiary hospital located in the western region of São Paulo state, Brazil. Methods: Medical records of children up to 18 years of age who were diagnosed with VL between January 2006 and December 2010 were reviewed. Geospatial analysis was performed using the ArcGIS 10.2 platform. Results: Sixty-three patients were enrolled in the study; the median age was 3.3 ± 3.3 years. The median time interval between the onset of clinical symptoms and diagnosis was 16.1 ± 11.1 days, and the median time in the pediatric ward was 18.0 ± 9.4 days. Liposomal amphotericin B was the first-line treatment in 90.5% of the patients and 9.6% relapsed. One patient died (1.6%), and 19% were submitted to the pediatric intensive care unit. Conclusion: The short interval between the onset of symptoms, diagnosis, and treatment and the reduced number of days of hospitalization certainly influenced the small number of deaths, relapses, and severity among the children infected with VL. However, the disease is spreading fast in the western region of São Paulo state. Thus, integrated actions and effective monitoring of the disease are needed to complement curative practices.

    In order to increase storage capacity and data transfer velocity by about three orders of magnitude compared to CD or magnetic disc it is necessary to work with optical techniques, especially with holography. About 100 TByte can be stored in a waver of an area of 50 cm{sup 2} via holograms which corresponds to a density of 2.10{sup 9} Byte/mm{sup 2}. Every hologram contains data of 1 MByte, so that parallel-processing is possible for read-out. Using high-speed CCD-arrays a read-out velocity of 1 MByte/{mu}sec can be reached. Further, holographic technics are very important in solid state physics. We will discuss the existence of a space charge field in Sr{sub 1-x}Ba{sub x}Nb{sub 2}O{sub 6} doped with cerium and the physical properties of metastable states, which are suited for information storage.

    In recent decades, practitioners and policymakers have turned to value-based payment initiatives to help contain spending on health care and to improve the quality of care. The Robert Wood Johnson Foundation funded 7 grantees across the country to design and implement value-based, multistakeholder payment reform projects in 6 states and 3 regions of the United States. As the external evaluator of these projects, we reviewed documents, conducted Internet searches, interviewed key stakeholders, cross-validated factual and narrative interpretation, and performed qualitative analyses to derive cross-site themes and implications for policy and practice. The nature of payment reform and its momentum closely reflects the environmental context of each project. Federal legislation such as the Patient Protection and Affordable Care Act and federal and state support for the development of the patient-centered medical home and accountable care organizations encourage value-based payment innovation, as do local market conditions for payers and providers that combine a history of collaboration with independent innovation and experimentation by individual organizations. Multistakeholder coalitions offer a useful facilitating structure for galvanizing payment reform. But to achieve the objectives of reduced cost and improved quality, multistakeholder payment innovation must overcome such barriers as incompatible information systems, the technical difficulties and transaction costs of altering existing billing and payment systems, competing stakeholder priorities, insufficient scale to bear population health risk, providers' limited experience with risk-bearing payment models, and the failure to align care delivery models with the form of payment. From the evidence adduced in this article, multistakeholder, value-based payment reform requires a trusted, widely respected "honest broker" that can convene and maintain the ongoing commitment of health plans, providers, and purchasers

    Injection of CO2 into the deep subsurface will affect physical and chemical conditions in the storage environment. Hence, geological CO2 storage can have potential impacts on groundwater resources. Shallow freshwater can only be affected if leakage pathways facilitate the ascent of CO2 or saline formation water. Leakage associated with CO2 storage cannot be excluded, but potential environmental impacts could be reduced by selecting suitable storage locations. In the framework of risk assessment, testing of models and scenarios against operational data has to be performed repeatedly in order to predict the long-term fate of CO2. Monitoring of a storage site should reveal any deviations from expected storage performance, so that corrective measures can be taken. Comprehensive R & D activities and experience from several storage projects will enhance the state of knowledge on geological CO2 storage, thus enabling safe storage operations at well-characterised and carefully selected storage sites while meeting the requirements of groundwater protection.

    Evidence of shifting dominance among major forest disturbance agent classes regionally to globally has been emerging in the literature. For example, climate-related stress and secondary stressors on forests (e.g., insect and disease, fire) have dramatically increased since the turn of the century globally, while harvest rates in the western US and elsewhere have declined. For shifts to be quantified, accurate historical forest disturbance estimates are required as a baseline for examining current trends. We report annual disturbance rates (with uncertainties) in the aggregate and by major change causal agent class for the conterminous US and five geographic subregions between 1985 and 2012. Results are based on human interpretations of Landsat time series from a probability sample of 7200 plots (30 m) distributed throughout the study area. Forest disturbance information was recorded with a Landsat time series visualization and data collection tool that incorporates ancillary high-resolution data. National rates of disturbance varied between 1.5% and 4.5% of forest area per year, with trends being strongly affected by shifting dominance among specific disturbance agent influences at the regional scale. Throughout the time series, national harvest disturbance rates varied between one and two percent, and were largely a function of harvest in the more heavily forested regions of the US (Mountain West, Northeast, and Southeast). During the first part of the time series, national disturbance rates largely reflected trends in harvest disturbance. Beginning in the mid-90s, forest decline-related disturbances associated with diminishing forest health (e.g., physiological stress leading to tree canopy cover loss, increases in tree mortality above background levels), especially in the Mountain West and Lowland West regions of the US, increased dramatically. Consequently, national disturbance rates greatly increased by 2000, and remained high for much of the decade. Decline

  5. Emergency planning for industrial hazards

    The European Communities have produced a Directive on the Major Accident Hazards of Certain Industrial Activities which sets out standards for the control and mitigation of the hazards presented by sites and storages which contain significant quantities of dangerous substances. An essential element of these controls is the provision of effective on-and off-site emergency plans. This conference explores the considerable research effort which is going on throughout the world in the improvement of systems for emergency planning. Attention was also drawn to areas where difficulties still exist, for example in predicting the consequences of an accident, the complexities of communication problems and the difficulties arising from involvement of the public. The proceedings are in six parts which deal with organisation implementing emergency planning; on- and off-site emergency planning and design; techniques for emergency plans; expenses and auditing of emergency plans; lessons learnt from the emergency management of major accidents; information to the public to and during emergencies.

    We theoretically study the propagation and storage of a classical field in a Λ -type atomic medium using coherent population oscillations (CPOs). We show that the propagation eigenmodes strongly relate to the different CPO modes of the system. Light storage in such modes is discussed by introducing a "populariton" quantity, a mixture of populations and field, by analogy to the dark state polariton used in the context of electromagnetically induced transparency light storage protocol. As experimentally shown, this memory relies on populations and is then—by contrast with usual Raman coherence optical storage protocols—robust to dephasing effects.

    We give a brief account of some aspects of Finkelstein’s quantum relativity, namely an extension of it that derives elements of macroscopic geometry and the Lagrangians of the standard model including gravity from a presumed quantum version of spacetime. These emerge as collective effects in this quantal substrate. Our treatment, which is largely self-contained, differs mathematically from that originally given by Finkelstein.

    During the 2009-2010 H1N1 pandemic, children and high-risk adults had priority for vaccination. Vaccine in short supply was allocated to states pro-rata by population, but vaccination rates as of January 2010 varied among states from 21.3% to 84.7% for children and 10.4% to 47.2% for high-risk adults. States had different campaign processes and decisions. To determine program and system factors associated with higher state pandemic vaccination coverage for children and high-risk adults during an emergency response with short supply of vaccine. Regression analysis of factors predicting state-specific H1N1 vaccination coverage in children and high-risk adults, including state campaign information, demographics, preventive or health-seeking behavior, preparedness funding, providers, state characteristics, and surveillance data. Our modeling explained variation in state-specific vaccination coverage with an adjusted R-squared of 0.82 for children and 0.78 for high-risk adults. We found that coverage of children was positively associated with programs focusing on school clinics and with a larger proportion of doses administered in public sites; negatively with the proportion of children in the population, and the proportion not visiting a doctor because of cost. The coverage for high-risk adults was positively associated with shipments of vaccine to "general access" locations, including pharmacy and retail, with the percentage of women with a Pap smear within the past 3 years and with past seasonal influenza vaccination. It was negatively associated with the expansion of vaccination to the general public by December 4, 2009. For children and high-risk adults, coverage was positively associated with the maximum number of ship-to-sites and negatively associated with the proportion of medically underserved population. Findings suggest that distribution and system decisions such as vaccination venues and providers targeted can positively impact vaccination rates for

    Full Text Available "It is not a coincidence that the century of war coincided with the century of central banking,” wrote Ron Paul, the libertarian candidate "sensation" for the presidential elections in 2008 and 2012, in the book End the Fed. This discussion explores in short, the powerful pamphlet by Major General Smedley Butler, "War is a Racket", demonstrating, specifically, who profited economically and who, in turn, bore the weight and violence of WW1, assuming that a war is never fought with the acquiescence of the population. However, this monograph goes further, looking for a reinterpretation of the official American history of the First World War through the lens of libertarian discourse. The aim is thus to understand, from another perspective, the fundamental cause of the paradigm shift from nonintervention to intervention taking place during this war, linking it to the project which led to the creation of the League of Nations and the growing importance of the US in the world. Finally, a fundamental connection will be established, exploring the theories argued in the book A Foreign Policy of Freedom, between the policies of Woodrow Wilson and the foreign policy of the United States throughout the 20th century and the beginning of the 21st.

  11. Effects of cold storage on field and laboratory performance of Trichogramma carverae (Hymenoptera: Trichogrammatidae) and the response of three Trichogramma spp. (T. carverae, T. nr. brassicae, and T. funiculatum) to cold.

    Delaying emergence of Trichogramma spp. is critical for commercial production. Here, diapause induction was considered for three species (Trichogramma nr. brassicae Bezdenko, Trichogramma carverae Oatman & Pinto, and Trichogramma funiculatum Carver), and the effect of storage temperature (4 degrees C, 8 degrees C, and 10 degrees C) and time (1-8 wk) was investigated for T. carverae. For all species, percentage of emergence was lowered after an initial diapause induction period (28 d at 14 degrees C and a photoperiod of 8:16 [L:D] h) and lowered further after 1-mo storage at 3 degrees C and a photoperiod of 0:24 (L:D) h. No wasps emerged after 2 mo of storage, suggesting that true diapause was not induced. The effect of 1-8-wk storage on wasp quality was investigated for T. carverae both in the laboratory and the field. Initial fieldwork suggested that this species could be successfully stored at 10 degrees C under continuous light (after 5-d development at 25 degrees C and a photoperiod of 16:8 [L:D] h) without reducing the ability of wasps to parasitize eggs in the field. In a second experiment, storage temperatures lower than 10 degrees C and storage times 3 wk or longer had a negative impact on emergence and longevity, and effects were not additive. Negative effects may partly reflect size changes, because size decreased in response to storage time, and there was an interaction between time and temperature effects on size. Storage time was the major factor influencing fecundity and field success; both fitness measures were reduced after storage of 3 wk or longer. T. carverae can therefore be successfully stored for up to 2 wk without detrimental effects, and 10 degrees C is the preferred storage temperature. T. carverae seems to survive unfavorable temperature conditions by entering a state of quiescence.

    Full Text Available When producing and utilizing hydrogen, its storage is one of the biggest problems. Hydrogen, as a gas, is extremely fluid with very low specific weight. Moreover, at a certain rate, the hydrogen-oxygen mixture is explosive. Therefore, the storage of hydrogen is relatively dangerous. A storage of liquid hydrogen in the natural zeolite, which is placed in large capacity battery, appears to be a suitable hydrogen storage method. Proposed and constructed pressure tank, large capacity battery, allows long-term and safe storage of liquid hydrogen, with the possibility to change its state from liquid to gaseous or contrarily in real time. Natural zeolite is an inert material with large internal surface area and high thermal capacity. In the future, presented large capacity battery VAZEP can be a part of the system for production and storage of electric energy generated by photovoltaic modules from the sun.

    Substance use and risk-taking are common during emerging adulthood, a transitional period when peer influences often increase and family influences decrease. Investigating relationships between social network features and substance use can inform community-based prevention programs. This study investigated whether substance use among emerging adults living in disadvantaged urban areas was influenced by peer and family social network messages that variously encouraged and discouraged substance use. Cross-sectional, naturalistic field study. Lower-income neighborhoods in Birmingham, Alabama, USA with 344 participants (110 males, 234 females, ages 15-25 years; mean = 18.86 years), recruited via respondent-driven sampling. During structured interviews conducted in community locations, the Alcohol, Smoking and Substance Involvement Screening Test assessed substance use and related problems. Predictor variables were network characteristics, including presence of substance-using peers, messages from friends and family members about substance use and network sources for health information. Higher substance involvement was associated with friend and family encouragement of use and having close peer network members who used substances (Ps risk (b = - 1.46, P < 0.05), whereas family discouragement had no protective association. Social networks appear to be important in both promoting and preventing substance use in disadvantaged young adults in the United States. © 2015 Society for the Study of Addiction.

    Using the Social Ecological Model, the individual, partner, social, and structural factors related to recent Latina immigrants' contraceptive use in an emerging immigrant community were explored. During September 2013-January 2014, door-to-door sampling was used in Birmingham, Alabama to recruit Latina immigrants who had lived in the United States (U.S.) for less than 5 years. Ten women with foreign-born children and 10 with only U.S.-born children completed in-depth interviews about their contraceptive use following migration. Women's narratives revealed interrelated barriers to using highly effective contraception after migrating to the U.S. Women had nuanced concerns about using hormonal contraception, which, when combined with other factors, led them to rely on condoms and withdrawal. Limited partner communication was a barrier to effective method use for some women, but partner attitudes that women should be responsible for contraception were less important. Weak female networks made it difficult for immigrants to learn about the U.S. health-care system, especially those with only U.S.-born children. Even once women accessed services, a full range of highly effective methods was not available or affordable. In emerging communities, integrated strategies that address immigrants' need for information and ensure access to affordable contraception would help women achieve their reproductive life goals.

    Full Text Available BACKGROUND: In 2009 the state government of Madhya Pradesh, India launched an emergency obstetric transportation service, Janani Express Yojana (JEY, to support the cash transfer program that promotes institutional delivery. JEY, a large scale public private partnership, lowers geographical access barriers to facility based care. The state contracts and pays private agencies to provide emergency transportation at no cost to the user. The objective was to study (a the utilization of JEY among women delivering in health facilities, (b factors associated with usage, (c the timeliness of the service. METHODS: A cross sectional facility based study was conducted in facilities that carried out > ten deliveries a month. Researchers who spent five days in each facility administered a questionnaire to all women who gave birth there to elicit socio-demographic characteristics and transport related details. RESULTS: 35% of women utilised JEY to reach a facility, however utilization varied between study districts. Uptake was highest among women from rural areas (44%, scheduled tribes (55%, and poorly educated women (40%. Living in rural areas and belonging to scheduled tribes were significant predictors for JEY usage. Almost 1/3 of JEY users (n = 104 experienced a transport related delay. DISCUSSION: The JEY service model complements the cash transfer program by providing transport to a facility to give birth. A study of the distribution of utilization in population subgroups suggests the intervention was successful in reaching the most vulnerable population, promoting equity in access. While 1/3 of women utilized the service and it saved them money; 30% experienced significant transport related delays in reaching a facility, which is comparable to women using public transportation. Further research is needed to understand why utilization is low, to explore if there is a need for service expansion at the community level and to improve the overall time

    Ophthalmic emergencies are common presenting complaints in an emergency room. Most ophthalmic emergencies can be treated and stabilized until an ophthalmologist can be consulted. Most ocular emergencies involve loss of vision, compromised globe integrity, or severe ocular pain. Delay in treating true emergencies may result ina blind eye or loss of an eye. This article discusses the clinical signs,diagnosis, and treatment as well as the prognosis of some of the more common ophthalmic emergencies.
