    This planning guide was developed under the direction of the U.S. Army and the Federal Emergency Management Agency (FEMA) which jointly coordinate and direct the development of the Chemical Stockpile Emergency Preparedness Program (CSEPP). It was produced to assist state, local, and Army installation planners in formulating and coordinating plans for chemical events that may occur at the chemical agent stockpile storage locations in the continental United States. This document provides broad planning guidance for use by both on-post and off-post agencies and organizations in the development of a coordinated plan for responding to chemical events. It contains checklists to assist in assuring that all important aspects are included in the plans and procedures developed at each Chemical Stockpile Disposal Program (CSDP) location. The checklists are supplemented by planning guidelines in the appendices which provide more detailed guidance regarding some issues. The planning guidance contained in this document will help ensure that adequate coordination between on-post and off-post planners occurs during the planning process. This planning guide broadly describes an adequate emergency planning base that assures that critical planning decisions will be made consistently at every chemical agent stockpile location. This planning guide includes material drawn from other documents developed by the FEMA, the Army, and other federal agencies with emergency preparedness program responsibilities. Some of this material has been developed specifically to meet the unique requirements of the CSEPP. In addition to this guidance, other location-specific documents, technical studies, and support studies should be used as needed to assist in the planning at each of the chemical agent stockpile locations to address the specific hazards and conditions at each location.

  2. Risk communications and the Chemical Stockpile Emergency-Planning Program

    Energy Technology Data Exchange (ETDEWEB)

    Vogt, B.M.; Sorensen, J.H.

    1994-09-01

    The CSEPP (Chemical Stockpile Emergency Preparedness Program) was created to improve emergency planning and response capabilities at the eight sites around the country that store chemical weapons. These weapons are scheduled to be destroyed in the near future. In preparation of the Draft Programmatic Environmental Impact Statement (DPEIS) for the Chemical Stockpile Disposal Program (CSDP), it was proposed that the Army mitigate accidents through an enhanced community emergency preparedness program at the eight storage sites. In 1986, the Army initiated the development of an Emergency Response Concept Plan (ERCP) for the CSDP, one of 12 technical support studies conducted during preparation of the Final Programmatic Environmental Impact Statement (FPEIS). The purpose of this document is to provide a fairly comprehensive source book on risk, risk management, risk communication research and recommended risk communication practices. It does not merely summarize each publication in the risk communication literature, but attempts to synthesize them along the lines of a set of organizing principles. Furthermore, it is not intended to duplicate other guidance manuals (such as Covello et al.`s manual on risk comparison). The source book was developed for the CSEPP in support of the training module on risk communications. Although the examples provided are specific to CSEPP, its use goes beyond that of CSEPP as the findings apply to a broad spectrum of risk communication topics. While the emphasis is on communication in emergency preparedness and response specific to the CSEPP, the materials cover other non-emergency communication settings. 329 refs.

  3. From nuclides to nerve gas: The development of the Chemical Stockpile Emergency Preparedness Exercise Program

    International Nuclear Information System (INIS)

    The Army and the Federal Emergency Management Agency established the Chemical Stockpile Emergency Preparedness Program (CSEPP), to improve emergency preparedness around each location storing the nation's aging stockpile of unitary chemical weapons. The CSEPP requires that a series of exercises be conducted at each location on a regular schedule. The CSEPP exercise program drew upon the existing Army and civilian exercises. Merging the exercise traditions of both the communities and installations into a joint exercise program acceptable to both sides and the particular nature of the hazard required a number of adjustments in the usual approaches. 14 refs., 1 fig

    As part of the Chemical Stockpile Disposal Program mandated by Public Law 99--145 (Department of Defense Authorization Act), an independent review is presented of the US Army Phase I environmental report for the disposal program at the Umatilla Depot Activity (UMDA) in Hermiston, Oregon. The Phase I report addressed new and additional concerns not incorporated in the final programmatic environmental impact statement (FPEIS). Those concerns were addressed by examining site-specific data for the Umatilla Depot Activity and by recommending the scope and content of a more detailed site-specific study. This independent review evaluates whether the new site-specific data presented in the Phase I report would alter the decision in favor of on-site disposal that was reached in the FPEIS, and whether the recommendations for the scope and content of the site-specific study are adequate. Based on the methods and assumptions presented in the FPEIS, the inclusion of more detailed site-specific data in the Phase I report does not change the decision reached in the FPEIS (which favored on-site disposal at UMDA). It is recommended that alternative assumptions about meteorological conditions be considered and that site-specific data on water, ecological, socioeconomic, and cultural resources; seismicity; and emergency planning and preparedness be considered explicitly in the site-specific EIS decision-making process. 7 refs., 1 fig.

    The primary focus of the Chemical Stockpile Emergency Preparedness Program (CSEPP) is to enhance the response capabilities of the eight US Army installations that store chemical weapons agent and of the communities immediately surrounding each Army storage installation. Exercises are a major component of the program and are conducted annually at each of the eight installations. Following each exercise, a report summarizing the results of the exercise is produced. To gain a better perspective on the site-specific and program-wide results of these exercises, the Project Manager for Chemical Stockpile Emergency Preparedness requested that Argonne National Laboratory develop a database containing the results of exercises held through June 1996. This document provides a summary of the process used to develop the CSEPP Exercise Results Database. The database provides CSEPP managers in the Department of the Army and the Federal Emergency Management Agency a method for tracking and analyzing exercise results. The report discusses the collection and coding of exercise data and provides tables to guide coding of future exercise results. An electronic copy of the database (CD-ROM) accompanies the report. This report focuses only on methods used to collect exercise data and develop the database; Volume 2 discusses the analysis of the data collected.

  6. Chemical Stockpile Disposal Program rapid accident assessment

    Energy Technology Data Exchange (ETDEWEB)

    Chester, C.V.

    1990-08-01

    This report develops a scheme for the rapid assessment of a release of toxic chemicals resulting from an accident in one of the most chemical weapon demilitarization plants or storage areas. The system uses such inputs as chemical and pressure sensors monitoring the plant and reports of accidents radioed to the Emergency Operations Center by work parties or monitoring personnel. A size of release can be estimated from previous calculations done in the risk analysis, from back calculation from an open-air chemical sensor measurement, or from an estimated percentage of the inventory of agent at the location of the release. Potential consequences of the estimated release are calculated from real-time meteorological data, surrounding population data, and properties of the agent. In addition to the estimated casualties, area coverage and no-death contours vs time would be calculated. Accidents are assigned to one of four categories: community emergencies, which are involve a threat to off-site personnel; on-post emergencies, which involve a threat only to on-site personnel; advisory, which involves a potential for threat to on-site personnel; and chemical occurrence, which can produce an abnormal operating condition for the plant but no immediate threat to on-site personnel. 9 refs., 20 tabs.

  7. Joint stockpiling and emergency sharing of oil: Arrangements for regional cooperation in East Asia

    International Nuclear Information System (INIS)

    The East Asia region includes three of the world's top five oil-importing nations-China, Japan, and the Republic of Korea. As a consequence, international oil supply disruptions and oil price spikes, and their effects on the economies of the region, have historically been of significant concern. Each of these three nations, as well as other nations in East Asia, has developed or is developing their own strategic oil stockpiles, but regional coordination in stockpiling arrangements and sharing of oil stocks in an emergency could provide significant benefits. This article describes the overall oil supply security situation in East Asia, reviews the attributes of different stockpiling arrangements to address energy supply security concerns, summarizes ongoing national approaches to stockpiling in East Asia, describes the development of joint oil stockpile initiatives in the region, and suggests the most attractive options for regional cooperation on oil stockpiling issues. - Highlights: → Rising oil consumption will make East Asia more vulnerable to energy insecurity. → There have been various dialogs on the need for a joint regional oil stockpile. → No serious joint oil stockpiling efforts have been made in East Asia to date. → Despite various impediments, diverse benefits justify oil stockpile cooperation.

    Some types of public health emergencies could result in large numbers of patients with respiratory failure who need mechanical ventilation. Federal public health planning has included needs assessment and stockpiling of ventilators. However, additional federal guidance is needed to assist states in further allocating federally supplied ventilators to individual hospitals to ensure that ventilators are shipped to facilities where they can best be used during an emergency. A major consideration in planning is a hospital's ability to absorb additional ventilators, based on available space and staff expertise. A simple pro rata plan that does not take these factors into account might result in suboptimal use or unused scarce resources. This article proposes a conceptual framework that identifies the steps in planning and an important gap in federal guidance regarding the distribution of stockpiled mechanical ventilators during an emergency.

  11. Stockpile strategy for China's emergency oil reserve: A dynamic programming approach

    International Nuclear Information System (INIS)

    China is currently accelerating construction of its strategic petroleum reserves. How should China fill the SPR in a cost-effective manner in the short-run? How might this affect world oil prices? Using a dynamic programming model to answer these questions, the objective of this paper is to minimize the stockpiling costs, including consumer surplus as well as crude acquisition and holding costs. The crude oil acquisition price in the model is determined by global equilibrium between supply and demand. Demand, in turn, depends on world market conditions including China's stockpile filling rate. Our empirical study under different market conditions shows that China's optimal stockpile acquisition rate varies from 9 to 19 million barrels per month, and the optimal stockpiling drives up the world oil price by 3–7%. The endogenous price increase accounts for 52% of total stockpiling costs in the base case. When the market is tighter or the demand function is more inelastic, the stockpiling affects the market more significantly and pushes prices even higher. Alternatively, in a disruption, drawdown from the stockpile can effectively dampen soaring prices, though the shortage is likely to leave the price higher than before the disruption. - Highlights: • China's SPR policies are examined by dynamic programming. • The optimal stockpile acquisition rate varies from 9 to 19 million barrels per month. • The optimal stockpiling drives up world oil price by 3–7%

  12. Chemical Stockpile Disposal Program: Review and comment on the Phase 1 environmental report for the Pueblo Depot Activity, Pueblo, Colorado

    International Nuclear Information System (INIS)

    As part of the Chemical Stockpile Disposal Program, an independent review is presented of the US Army Phase I environmental report for the disposal of chemical agents and munitions stored at the Pueblo Depot Activity (PUDA) in Pueblo, Colorado. The Phase I report addresses new and additional concerns not incorporated in the final programmatic environmental impact statement (FPEIS). These concerns are addressed by examining site-specific data for the PUDA. On the basis of our review of the Phase I report, we concluded that on-site meteorological data from December 1988 to June 1992 appear to be of insufficient quality to have been used instead of the off-site Pueblo airport data. No additional meteorological data have been collected since June 1992. The Phase I report briefly mentions problems with the air pollution control system. These problems will likely require the systems to be upgraded at the Johnston Atoll site and at each of the other depots in the continental United States. Without such improvements, the probability of accidents during start-up and shutdown would likely increase. The Army has a lessons-learned program to incorporate improvements into the design of future facilities. The Phase I report does not make any design change commitments. These issues need to be fully evaluated and resolved before any final conclusion concerning the adequacy of the decision in the FPEIS can be made with respect to the PUDA. With the exception of this issue, the inclusion of other more detailed site-specific data in the Phase I report does not change the decision reached in the FPEIS (which favored on-site disposal at the PUDA). We recommend that site-specific data on water, ecological, socioeconomic, and cultural resources and emergency planning and preparedness be considered explicitly in the site-specific EIS decision-making process

    Energy Technology Data Exchange (ETDEWEB)

    Feldman, D.L.; Dobson, J.E.

    1990-08-01

    This report examines the adequacy of current command and control systems designed to make timely decisions that would enable sufficient warning and protective response to an accident at the Edgewood area of Aberdeen Proving Ground (APG), Maryland, and at Pine Bluff Arsenal (PBA), Arkansas. Institutional procedures designed to facilitate rapid accident assessment, characterization, warning, notification, and response after the onset of an emergency and computer-assisted decision-making aids designed to provide salient information to on- and-off-post emergency responders are examined. The character of emergency decision making at APG and PBA, as well as potential needs for improvements to decision-making practices, procedures, and automated decision-support systems (ADSSs), are described and recommendations are offered to guide equipment acquisition and improve on- and off-post command and control relationships. We recommend that (1) a continued effort be made to integrate on- and off-post command control, and decision-making procedures to permit rapid decision making; (2) the pathways for alert and notification among on- and off-post officials be improved and that responsibilities and chain of command among off-post agencies be clarified; (3) greater attention be given to organizational and social context factors that affect the adequacy of response and the likelihood that decision-making systems will work as intended; and (4) faster improvements be made to on-post ADSSs being developed at APG and PBA, which hold considerable promise for depicting vast amounts of information. Phased development and procurement of computer-assisted decision-making tools should be undertaken to balance immediate needs against available resources and to ensure flexibility, equity among sites, and compatibility among on- and off-post systems. 112 refs., 6 tabs.

  15. THE BNL ASTD FIELD LAB - NEAR - REAL - TIME CHARACTERIZATION OF BNL STOCKPILED SOILS TO ACCELERATE COMPLETION OF THE EM CHEMICAL HOLES PROJECT

    International Nuclear Information System (INIS)

    As of October 2001, approximately 7,000 yd3 of stockpiled soil remained at Brookhaven National Laboratory (BNL) after the remediation of the BNL Chemical/Animal/Glass Pits disposal area. The soils were originally contaminated with radioactive materials and heavy metals, depending on what materials had been interred in the pits, and how the pits were excavated. During the 1997 removal action, the more hazardous/radioactive materials were segregated, along with, chemical liquids and solids, animal carcasses, intact gas cylinders, and a large quantity of metal and glass debris. Nearly all of these materials have been disposed of. In order to ensure that all debris was removed and to characterize the large quantity of heterogeneous soil, BNL initiated an extended sorting, segregation, and characterization project directed at the remaining soil stockpiles. The project was co-funded by the Department of Energy Environmental Management Office (DOE EM) through the BNL Environmental Restoration program and through the DOE EM Office of Science and Technology Accelerated Site Technology Deployment (ASTD) program. The focus was to remove any non-conforming items, and to assure that mercury and radioactive contaminant levels were within acceptable limits for disposal as low-level radioactive waste. Soils with mercury concentrations above allowable levels would be separated for disposal as mixed waste. Sorting and segregation were conducted simultaneously. Large stockpiles (ranging from 150 to 1,200 yd3) were subdivided into manageable 20 yd3 units after powered vibratory screening. The 1/2-inch screen removed almost all non-conforming items (plus some gravel). Non-conforming items were separated for further characterization. Soil that passed through the screen was also visually inspected before being moved to a 20 yd3 ''subpile.'' Eight samples from each subpile were collected after establishing a grid of four quadrants: north, east, south and west, and two layers: top and

    2008-04-18

    The future of the US nuclear arsenal continues to be guided by two distinct drivers: the preservation of world peace and the prevention of further proliferation through our extended deterrent umbrella. Timely implementation of US nuclear policy decisions depends, in part, on the current state of stockpile weapons, their delivery systems, and the supporting infrastructure within the Department of Defense (DoD) and the Department of Energy's National Nuclear Security Administration (NNSA). In turn, the present is a product of past choices and world events. Now more than ever, the nuclear weapons program must respond to the changing global security environment and to increasing budget pressures with innovation and sound investments. As the nation transitions to a reduced stockpile, the successes of the Stockpile Stewardship Program (SSP) present options to transition to a sustainable complex better suited to stockpile size, national strategic goals and budgetary realities. Under any stockpile size, we must maintain essential human capital, forefront capabilities, and have a right-sized effective production capacity. We present new concepts for maintaining high confidence at low stockpile numbers and to effectively eliminate the reserve weapons within an optimized complex. We, as a nation, have choices to make on how we will achieve a credible 21st century deterrent.

    Full Text Available In the recent time, considerable interest has grown concerning the presence of the emerging industrial chemicals, EmIC. They are contaminants that have possible pathway to enter to the environment and they are dominantly released by industrial and anthropogenic activities. EmIC are applied in different fields using as industrial chemicals (new and recently recognized, global organic contaminants (flame retardant chemicals, pharmaceuticals (for both human and animal uses, endocrine-modulating compounds, biological metabolites, personal care products, household chemicals, nanomaterial (energy storage products, lubricants, anticorrosive and agriculture chemicals and others that are applied to a wide variety of everyday items such as clothing, upholstery, electronics and automobile interiors. NORMAN (Network of reference laboratories for monitoring of emerging environmental pollutants has established an open, dynamic, list of emerging substances and pollutants. EmIC have been recently detected in the environment due to their long-term presence, pseudo-persistence and increased use. Improvements in sophisticated analytical methods and time integrative passive sampling have enabled the identification and quantification of EmIC, in very low concentrations (ppb, ppt and lower, which likely have been present in all environmental mediums for decades. Passive technology is an innovative technique for the time-integrated measurement of emerging contaminants in water, sediment, soil and air. Passive samplers are simple handling cost-effective tool that could be used in environmental monitoring programmes. These devices are now being considered as a part of an emerging strategy for monitoring a range of emerging industrial chemicals and priority pollutants in the aquatic environment. EmIC are substances that are not included in the routine monitoring programmes and whose fate, behaviour and (ecotoxicological effects are still not well understood. Emerging

  1. Chemical toxicity approach for emergency response

    International Nuclear Information System (INIS)

    In the event of an airborne release of chemical agent or toxic industrial chemical by accidental or intentional means, emergency responders must have a reasonable estimate of the location and size of the resulting hazard area. Emergency responders are responsible for warning persons downwind of the hazard to evacuate or shelter-in-place and must know where to look for casualties after the hazard has passed or dissipated. Given the same source characterization, modern hazard assessment models provide comparable concentration versus location and time estimates. Even urban hazard assessment models often provide similar predictions. There is a major shortcoming, though, in applying model output to estimating human toxicity effects. There exist a variety of toxicity values for non-lethal effects ranging from short-term to occupational to lifetime exposures. For health and safety purposes, these estimates are all safe-sided in converting animal data to human effects and in addressing the most sensitive subset of the population. In addition, these values are usually based on an assumed 1 hour exposure duration at constant concentration and do not reflect either a passing clouds concentration profile or duration. Emergency responders need expected value toxicity parameters rather than the existing safe-sided ones. This presentation will specify the types of toxicity values needed to provide appropriate chemical hazard estimates to emergency responders and will demonstrate how dramatically their use changes the hazard area.(author)

    2013-01-15

    Stockpiled coal undergoes atmospheric oxidation and desorption processes during open air storage. These processes release gases to the environment which may effect health and safety by their toxicity and flammability. In extreme cases, this could lead to a fire. This report discusses gaseous emissions from coal stockpiles. It covers gas emission mechanisms, and gas sampling and testing methods, before examining in more detail the principal gases that have been emitted. It concludes that there is limited research in this area and more data are needed to evaluate the risks of gaseous emissions. Some methods used to prevent coal self-heating and spontaneous combustion can be applied to reduce emissions from coal stockpiles.

    The potential for chemical weapons to be used in terrorism is a real possibility. Classes of chemical weapons include nerve agents, vesicants (blister agents), choking agents, incapacitating agents, riot control agents, blood agents, and toxic industrial chemicals. The nerve agents work by blocking the actions of acetylcholinesterase leading to a cholinergic syndrome. Nerve agents include sarin, tabun, VX, cyclosarin, and soman. The vesicants include sulfur mustard and lewisite. The vesicants produce blisters and also damage the upper airways. Choking agents include phosgene and chlorine gas. Choking agents cause pulmonary edema. Incapacitating agents include fentanyl and its derivatives and adamsite. Riot control agents include Mace and pepper spray. Blood agents include cyanide. The mechanism of toxicity for cyanide is blocking oxidative phosphorylation. Toxic industrial chemicals include agents such as formaldehyde, hydrofluoric acid, and ammonia. PMID:22080590

Though still in the research stage, fusion can be developed in time to meet future military requirements. Much of the necessary technology will be developed by the ongoing magnetic fusion energy program. However, a specific program to develop the nuclear technology required for materials production is needed if fusion is to become a viable option for a new production complex around the turn of the century

    Stockpile stewardship is the retention of nuclear weapons in the stockpile beyond their original design life. These older weapons have potential changes inconsistent with the original design intent and military specifications. The Stockpile Stewardship Program requires us to develop high-fidelity, physics-based capabilities to predict, assess, certify and design nuclear weapons without conducting a nuclear test. Each year, the Lab Directors are required to provide an assessment of the safety, security, and reliability our stockpile to the President of the United States. This includes assessing whether a need to return to testing exists. This is a talk to provide an overview of Stockpile Stewardship's scientific requirements and how stewardship has changed in the absence of nuclear testing. The talk is adapted from an HQ talk to the War college, and historical unclassified talks on weapon's physics.

    Objective: To assess the emergency care outcomes of acute chemical poisoning cases in tertiary care settings in Rawalpindi, Pakistan. Methods: The data were extracted from an injury surveillance study conducted in the emergency departments (ED) of three tertiary care hospitals of Rawalpindi city from July 2007 to June 2008. The World Health Organization standard reporting questionnaire (one page) was used for recording information. Associations of patients' characteristics with ED care outcomes, i.e., admitted vs. discharged were assessed using logistic regression models. Results: Of 62 530 injury cases reported, chemical poisoning was identified in 434 (0.7%) cases. The most frequent patient characteristics were poisoning at home (61.9%), male gender (58.6%), involving self-harm (46.0%), and youth aged 20–29 years (43.3%). Over two-thirds of acute poisoning cases (69.0%) were admitted. Acute poisoning cases were more likely to be admitted if they were youth aged 10–19 years [odds ratio (OR)=4.41], when the poisoning occurred at home (OR=21.84), and was related to self-harm (OR=18.73) or assault (OR=7.56). Conclusions: Findings suggest that controlling access of poisonous substances in youth and at homes might reduce related ED care burden. Safety promotion agencies and emergency physicians can use these findings to develop safety messages.

    Dr. Miller's Introduction: We are becoming more and more aware that many alcoholics and chemically dependent individuals also suffer from a psychiatric disorder. This reality emerges now after a period in which the possibility of coexisting mental and addictive disorders was often denied by the alcoholism and drug fields. Psychiatrists and other mental health professionals need to be alert to patients with these dual disorders so that relapses of both the dependency and the psychiatric disorder can be averted. This month's column presents useful guidelines to help professionals deal effectively with this difficult problem. PMID:2714747

  19. Boltzmann Equation Solver Adapted to Emergent Chemical Non-equilibrium

    Birrell, Jeremiah

    2014-01-01

    We present a novel method to solve the spatially homogeneous and isotropic relativistic Boltzmann equation. We employ a basis set of orthogonal polynomials dynamically adapted to allow emergence of chemical non-equilibrium. Two time dependent parameters characterize the set of orthogonal polynomials, the effective temperature $T(t)$ and phase space occupation factor $\\Upsilon(t)$. In this first paper we address (effectively) massless fermions and derive dynamical equations for $T(t)$ and $\\Upsilon(t)$ such that the zeroth order term of the basis alone captures the number density and energy density of each particle distribution. We validate our method and illustrate the reduced computational cost and the ability to represent final state chemical non-equilibrium by studying a model problem that is motivated by the physics of the neutrino freeze-out processes in the early Universe, where the essential physical characteristics include reheating from another disappearing particle component ($e^\\pm$-annihilation).

  20. From chemical reactions to evolution: Emergence of species

    The Chemoton model constitutes a minimalistic description of a protocell unit. The original formulation assumes three coupled chemical networks, representing a proto-metabolism, a template duplication and the membrane growth. An improved version is here proposed that explicitly incorporates the effects of the volume changes, due to the membrane growth. A stochastic mechanism is also introduced that mimics a stochastic source of error in the template duplication process. Numerical simulations are performed to monitor the time evolution of a family of protocells, under the chemoton hypothesis. An open-ended Darwinian evolution under the pressure of the environment is reproduced thus allowing to conclude that differentiation into species is an emergent property of the model.

    Artificial protocellular compartments and lipid vesicles have been used as model systems to understand the origins and requirements for early cells, as well as to design encapsulated reactors for biotechnology. One prominent feature of vesicles is the semi-permeable nature of their membranes, able to support passive diffusion of individual solute species into/out of the compartment, in addition to an osmotic water flow in the opposite direction to the net solute concentration gradient. Crucially, this water flow affects the internal aqueous volume of the vesicle in response to osmotic imbalances, in particular those created by ongoing reactions within the system. In this theoretical study, we pay attention to this often overlooked aspect and show, via the use of a simple semi-spatial vesicle reactor model, that a changing solvent volume introduces interesting non-linearities into an encapsulated chemistry. Focusing on bistability, we demonstrate how a changing volume compartment can degenerate existing bistable reactions, but also promote emergent bistability from very simple reactions, which are not bistable in bulk conditions. One particularly remarkable effect is that two or more chemically-independent reactions, with mutually exclusive reaction kinetics, are able to couple their dynamics through the variation of solvent volume inside the vesicle. Our results suggest that other chemical innovations should be expected when more realistic and active properties of protocellular compartments are taken into account. PMID:25590570

    The U.S. National Academies released a report in 2012 on technical issues related to the Comprehensive Test Ban Treaty. One important question addressed therein is whether the U.S. could maintain a safe, secure, and reliable nuclear-weapons stockpile in the absence of nuclear-explosion testing. Here we discuss two main conclusions from the 2012 Academies report, which we paraphrase as follows: 1) Provided that sufficient resources and a national commitment to stockpile stewardship are in place, the U.S. has the technical capabilities to maintain a safe, secure, and reliable stockpile of nuclear weapons into the foreseeable future without nuclear-explosion testing. 2) Doing this would require: a) a strong weapons science and engineering program that addresses gaps in understanding; b) an outstanding workforce that applies deep and broad weapons expertise to deliver solutions to stockpile problems; c) a vigorous, stable surveillance program that delivers the requisite data; d) production facilities that meet stewardship needs. We emphasize that these conclusions are independent of CTBT ratification-they apply provided only that the U.S. continues its nuclear-explosion moratorium.

We find stark evidence of both search and stockpiling behavior.

  6. Modeling the filtration ability of stockpiled filtering facepiece

    2016-03-01

    Filtering facepiece respirators (FFR) are often stockpiled for use during public health emergencies such as an infectious disease outbreak or pandemic. While many stockpile administrators are aware of shelf life limitations, environmental conditions can lead to premature degradation. Filtration performance of a set of FFR retrieved from a storage room with failed environmental controls was measured. Though within the expected shelf life, the filtration ability of several respirators was degraded, allowing twice the penetration of fresh samples. The traditional picture of small particle capture by fibrous filter media qualitatively separates the effect of inertial impaction, interception from the streamline, diffusion, settling, and electrostatic attraction. Most of these mechanisms depend upon stable conformational properties. However, common FFR rely on electrets to achieve their high performance, and over time heat and humidity can cause the electrostatic media to degrade. An extension of the Langevin model with correlations to classical filtration concepts will be presented. The new computational model will be used to predict the change in filter effectiveness as the filter media changes with time.

  8. Thorium Nitrate Stockpile Drum Characterization Report

    International Nuclear Information System (INIS)

    Thorium nitrate (ThN) has been stored at depots for several decades and the Defense National Stockpile Center (DNSC) has evaluated options for its disposition. In support of this project, Oak Ridge National Laboratory (ORNL) has directed a characterization campaign for the ThN. The analytical results lead to the following conclusions: the ThN could be classified as LSA-1; the ThN does not contain hazardous contaminants at concentrations that would cause it to be categorized as a mixed waste if were declared to be a waste; the ThN is not required to be classfied as a Division 5.1 oxidizer per the US Dept. of Transportation definition; and, the disposal of the ThN would not be regulated by the Resource Conservation and Recovery Act and thus it could be accepted for disposal at the Nevada Test Site. This report disucsses the regulatory requirements involved with the packaging, transportation, and disposal of the ThN stockpile at the NTS. It also provides background information about the ThN stockpile, the current packaging configurations, and the current storage arrangements. The reader is also provided a description of the ThN and headspace gas sampling activities that wer conducted in 2002 and 2003 respectively. The basis for using ISO containers to transport and dispose of the ThN is discussed

    1999-04-01

    In 1991 the Los Alamos National Laboratory (LANL) launched a program to develop a comprehensive database of warhead storage conditions. Because of the extended lifetimes expected of the Stockpile, it became desirable to obtain as much detailed information on the storage environments as possible. Temperature and relative humidity at various facilities capable of storing and/or handling nuclear weapons were used as monitoring locations. The Stockpile Monitor Program (SMP) was implemented in a variety of locations as illustrated in a figure. Probably the most useful data come from the most extreme conditions monitored. The hottest outside temperatures and relative humidities come from Barksdale, while some of the lowest relative humidity values come from Nellis, which continue to be monitored. The coldest conditions come from Grand Forks, Griffiss, and KI Sawyer, none of which are presently being monitored. For this reason, the authors would like to begin monitoring Minot, ND. The outside extreme temperatures are ameliorated by the structures to a significant degree. For example, the hottest outside temperature (120 F) is contrasted by the corresponding cooler inside temperature (85 F), and the coldest outside temperature ({minus}35 F) is contrasted by the corresponding warmer inside temperature (+25 F). These data have become useful for calculations related to stockpile-to-target sequence (STS) and other analyses. SMP information has been provided to a number of outside agencies.

    For several years, Oak Ridge National Laboratory (ORNL) has been supporting the Defense Logistics Agency-Defense National Stockpile Center with stewardship of a thorium nitrate (ThN) stockpile. The effort for fiscal year 2002 was to prepare a sampling and analysis plan and to use the activities developed in the plan to characterize the ThN stockpile. The sampling was performed in June and July 2002 by RWE NUKEM with oversight by ORNL personnel. The analysis was performed by Southwest Research Institute of San Antonio, Texas, and data validation was performed by NFT, Inc., of Oak Ridge, Tennessee. Of the {approx} 21,000 drums in the stockpile, 99 were sampled and 53 were analyzed for total metals composition, radiological constituents (using alpha and gamma spectrometry), and oxidizing characteristics. Each lot at the Curtis Bay Depot was sampled. Several of the samples were also analyzed for density. The average density of the domestic ThN was found to be 1.89 {+-} 0.08 g/cm{sup 3}. The oxidizer test was performed following procedures issued by the United Nations in 1999. Test results indicated that none of the samples tested was a Division 5.1 oxidizer per Department of Transportation definition. The samples were analyzed for total metals following the U.S. Environmental Protection Agency methods SW-846-6010B and 6020 (EPA 2003) using a combination of inductively coupled plasma--atomic emission spectroscopy and inductively coupled plasma--mass spectroscopy techniques. The results were used to compare the composition of the eight Resource Conservation and Recovery Act metals present in the sample (arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver) to regulatory limits. None of the samples was found to be hazardous for toxicity characteristics. The radiological analyses confirmed, when possible, the results obtained by the inductively coupled plasma analyses. These results--combined with the historical process knowledge acquired on the material

    In response to the end of the Cold War and changes in the world's political regimes, the United States is not producing new-design nuclear weapons. Instead, the emphasis of the U.S. nuclear weapons program is on reducing the size of the Nation's nuclear stockpile by dismantling existing nuclear weapons. The Department of Energy (DOE) has been directed by the President and Congress to maintain the safety and reliability of the reduced nuclear weapons stockpile in the absence of underground nuclear testing. In order to fulfill that responsibility, DOE has developed a Stockpile Stewardship and Management Program to provide a single highly integrated technical program for maintaining the continued safety and reliability of the nuclear stockpile.

  15. Antiviral resistance during pandemic influenza: implications for stockpiling and drug use

    2009-01-01

    Full Text Available Abstract Background The anticipated extent of antiviral use during an influenza pandemic can have adverse consequences for the development of drug resistance and rationing of limited stockpiles. The strategic use of drugs is therefore a major public health concern in planning for effective pandemic responses. Methods We employed a mathematical model that includes both sensitive and resistant strains of a virus with pandemic potential, and applies antiviral drugs for treatment of clinical infections. Using estimated parameters in the published literature, the model was simulated for various sizes of stockpiles to evaluate the outcome of different antiviral strategies. Results We demonstrated that the emergence of highly transmissible resistant strains has no significant impact on the use of available stockpiles if treatment is maintained at low levels or the reproduction number of the sensitive strain is sufficiently high. However, moderate to high treatment levels can result in a more rapid depletion of stockpiles, leading to run-out, by promoting wide-spread drug resistance. We applied an antiviral strategy that delays the onset of aggressive treatment for a certain amount of time after the onset of the outbreak. Our results show that if high treatment levels are enforced too early during the outbreak, a second wave of infections can potentially occur with a substantially larger magnitude. However, a timely implementation of wide-scale treatment can prevent resistance spread in the population, and minimize the final size of the pandemic. Conclusion Our results reveal that conservative treatment levels during the early stages of the outbreak, followed by a timely increase in the scale of drug-use, will offer an effective strategy to manage drug resistance in the population and avoid run-out. For a 1918-like strain, the findings suggest that pandemic plans should consider stockpiling antiviral drugs to cover at least 20% of the population.

    In addition to property damage and loss of lives, environment pollution, such as water pollution and air pollution caused by accidents in chemical industrial parks (CIPs) is a significant issue in China. An emergency response system (ERS) was therefore planned to properly and proactively cope with safety incidents including fire and explosions occurring in the CIPs in this study. Using a scenario analysis, the stages of emergency response were divided into three levels, after introducing the domino effect, and fundamental requirements of ERS design were confirmed. The framework of ERS was composed mainly of a monitoring system, an emergency command center, an action system, and a supporting system. On this basis, six main emergency rescue steps containing alarm receipt, emergency evaluation, launched corresponding emergency plans, emergency rescue actions, emergency recovery, and result evaluation and feedback were determined. Finally, an example from the XiaoHu Chemical Industrial Park (XHCIP) was presented to check on the integrality, reliability, and maneuverability of the ERS, and the result of the first emergency drill with this ERS indicated that the developed ERS can reduce delays, improve usage efficiency of resources, and raise emergency rescue efficiency.

    Because the goal of emergency preparedness for both chemical and nuclear hazards is to reduce human exposure to hazardous materials, this paper examines the interchange of lessons learned from emergency planning and accident experience in both industries. While the concerns are slightly different, sufficient similarity is found for each to draw implications from the others experience. Principally the chemical industry can learn from the dominant planning experience associated with nuclear power plants, while the nuclear industry can chiefly learn from the chemical industry's accident experience. 23 refs

    The current stockpile of energetic materials requiring disposal contains about half a million tons. Through 2001, over 2.1 million tons are expected to pass through the stockpile for disposal. Safe and environmentally acceptable methods for disposing of these materials are needed. This project is developing safe, economical, and environmentally sound processes using biocatalyst (enzymes) to degrade energetic materials and to convert them into economically valuable products. Alternative methods for destroying these materials are hazardous, environmentally unacceptable, and expensive. These methods include burning, detonation, land and sea burial, treatment at high temperature and pressure, and treatment with harsh chemicals. Enzyme treatment operates at room temperature and atmospheric pressure in a water solution.

Methods A face-to-face semi-structured interview was carried out with the Nurse Manager or a nominated deputy in all 18 Emergency Departments in the Region. Results 16/18 departments had a written chemical incident plan but only 7 had the plan available at interview. All had a designated decontamination area but only 11 felt that they were adequately equipped. 12/18 had a current training programme for chemical incident management and 3 had no staff trained in decontamination. 13/18 could contain contaminated water from casualty decontamination and 6 could provide shelter for casualties before decontamination. Conclusion We have identified major inconsistencies in the preparedness of North West Emergency Departments for managing chemical incidents. Nationally recognized standards on incident planning, facilities, equipment and procedures need to be agreed and implemented with adequate resources. Issues of environmental safety and patient dignity and comfort should also be addressed.

    2007-01-01

    Introduction Since the enactment of the Clean Water Act in 1972, awareness of the quality of the Nation's water has continued to improve. Despite improvements to wastewater-treatment systems and increased regulation on waste discharge, bacterial and chemical contamination is still a problem for many rivers and lakes throughout the United States. Pathogenic microorganism and newly recognized chemical contaminants have been found in waters that are used for drinking water and recreation (Rose and Grimes, 2001; Kolpin and others, 2002). This summary of bacteria and emerging-chemical-contaminant monitoring in the St. Clair River/Lake St. Clair Basin (fig. 1) was initiated by the Lake St. Clair Regional Monitoring Project (LSCRMP) in 2003, in cooperation with the Michigan Department of Environmental Quality (MDEQ), the Counties of Macomb, Oakland, St. Clair, and Wayne, and the U.S. Geological Survey (USGS).

  20. CMSMAP : oil, chemical, search and rescue, and marine emergency response crisis management system

    International Nuclear Information System (INIS)

    This paper describes a newly developed Crisis Management System (CMS) which makes it possible to view oil and chemical spills on the seafloor. The CMS is designed to run in a network environment, so that multiple stations can be used cooperatively to respond to a spill incident. It was developed by the Maritime and Port Authority in Singapore and represents a singular integration of a ship's bridge simulator hardware and software. It incorporates numerical models and emergency response software. The CMS is installed in a specifically designed building at the Singapore Polytechnic University, and is integrated with two shipping bridge simulators. One user interface has access to models dealing with oil spills, chemical spills, search and rescues, marine emergencies, and nuclear disasters. The interface is linked to a response management system. The entire system is used to train response personnel to marine emergencies. The histories and costs of planned response activities are described and logged for reference purposes. Estimates of damages associated with spills can be obtained. Alternative response plans can also be determined. Further research in 2002 will focus on developing real time response. 3 refs., 6 figs

  2. Fuel cycle and waste management. 7. Thorium Nitrate Stockpile Stewardship and Disposition Technical Basis

    International Nuclear Information System (INIS)

    Oak Ridge National Laboratory (ORNL) is performing work for the Defense Logistics Agency (DLA) of the U.S. Department of Defense (DOD) to assist in a future determination of the disposition for thorium nitrate hydrate [Th(NO3)4.5H2O] currently stored at Hammond, Indiana, and Curtis Bay, Maryland. The DLA has ∼3500 tons of ThN contained in 21 000 drums of various configurations. This material has been declared surplus to the needs of the DOD. The ORNL efforts will supply technical input to quantify the potential for use in a thorium fuel cycle and identify characterization requirements and processing requirements consistent with available waste disposition pathways. The Defense National Support Command stores ∼7 million pounds of thorium nitrate crystals (hydrate form) at two depot locations in the United States (75 wt% at the Curtis Bay, Maryland, depot and 25 wt% at the Hammond, Indiana, depot). The managing agency is the DLA. An upgrade evaluation is required to define and control risks and costs associated with long-term management of the thorium nitrate stockpile. Technical studies are underway to determine the most viable options to be compared against continued storage in the present conditions. The generalized alternatives for technical analysis include the following: A. Retain the stockpile in the thorium nitrate form for disposal. B. Retain the stockpile in the thorium nitrate form for long-term storage. C. Process the stockpile to reduce the thorium nitrate to a suitable thorium form for disposal, without preserving chemical purity. D. Process the stockpile to reduce the thorium nitrate to pure thorium oxide for long-term storage. The technical assessment of option results is the focus of this paper. The methodology for analytical characterization is included because strategies are impacted by whether or not the ThN falls into a hazardous waste category. Baseline location and other relevant information are presented, as impact options, from

    The Umatilla Depot Activity (UMDA) near Hermiston, Oregon, is one of eight US Army installations in the continental United States where lethal unitary chemical agents and munitions are stored, and where destruction of agents and munitions is proposed under the Chemical Stockpile Disposal Program (CSDP). The chemical agent inventory at UMDA consists of 11.6%, by weight, of the total US stockpile. The destruction of the stockpile is necessary to eliminate the risk to the public from continued storage and to dispose of obsolete and leaking munitions. In 1988 the US Army issued a Final Programmatic Environmental Impact Statement (FPEIS) for the CSDP that identified on-site disposal of agents and munitions as the environmentally preferred alternative (i.e., the alternative with the least potential to cause significant adverse impacts), using a method based on five measures of risk for potential human health and ecosystem/environmental effects; the effectiveness and adequacy of emergency preparedness capabilities also played a key role in the FPEIS selection methodology. In some instances, the FPEIS included generic data and assumptions that were developed to allow a consistent comparison of potential impacts among programmatic alternatives and did not include detailed conditions at each of the eight installations. The purpose of this Phase 1 report is to examine the proposed implementation of on-site disposal at UMDA in light of more recent and more detailed data than those included in the FPEIS. Specifically, this Phase 1 report is intended to either confirm or reject the validity of on-site disposal for the UMDA stockpile. Using the same computation methods as in the FPEIS, new population data were used to compute potential fatalities from hypothetical disposal accidents. Results indicate that onsite disposal is clearly preferable to either continued storage at UMDA or transportation of the UMDA stockpile to another depot for disposal.

  7. Uranium purchasing and stockpiling policies of European utilities

    International Nuclear Information System (INIS)

    Most European utilities almost entirely depend on uranium imports. Around 1970 there was a worldwide oversupply of uranium, and utilities concluded short and medium term supply contracts for initial power plant programs. A few years later the situation had changed, with uranium becoming scarce and expensive. Many European utilities decided to participate, directly or indirectly, in the exploration and development of uranium resources. In 1984 most utilities believed that long term contracts from each of the big producer regions should supply 20-25% of their demand. Some remaining demand was reserved for the spot market and reprocessed fuel. This buying policy has t be supplemented by uranium stockpiles corresponding to the demand for the coming two years. However, with the declining worldwide economy power demand has not grown as predicted, and supply contracts have obliged utilities to take delivery of more uranium than needed. Stockpiles have grown larger than planned. (L.L.) (7 figs.)

  8. Emergency core cooling system sump chemical effects on strainer head loss

    International Nuclear Information System (INIS)

    Chemical precipitates formed in the recovery water following a Loss of Coolant Accident (LOCA) have the potential to increase head loss across the Emergency Core Cooling System (ECCS) strainer, and could lead to cavitation of the ECCS pumps, pump failure and loss of core cooling. AECL, as a strainer vendor and research organization, has been involved in the investigation of chemical effects on head loss for its CANDU® and Pressurized Water Reactor (PWR) customers. The chemical constituents of the recovery sump water depend on the combination of chemistry control additives and the corrosion and dissolution products from metals, concrete, and insulation materials. Some of these dissolution and corrosion products (e.g., aluminum and calcium) may form significant quantities of precipitates. The presence of chemistry control additives such as sodium hydroxide, trisodium phosphate and boric acid can significantly influence the precipitates formed. While a number of compounds may be shown to be thermodynamically possible under the conditions assumed for precipitation, kinetic factors play a large role in the morphology of precipitates. Precipitation is also influenced by insulation debris, which can trap precipitates and act as nucleation sites for heterogeneous precipitation. This paper outlines the AECL approach to resolving the issue of chemical effects on ECCS strainer head loss, which included modeling, bench top testing and reduced-scale testing; the latter conducted using a temperature-controlled variable-flow closed-loop test rig that included an AECL Finned Strainer® test section equipped with a differential pressure transmitter. Models of corrosion product release and the effects of precipitates on head loss will also be presented. Finally, this paper discusses the precipitates found in test debris beds and presents a possible method for chemical effects head loss modeling. (author)

    The chemical-specific risk-based paradigm that informs monitoring and assessment of environmental contaminants does not apply well to the many thousands of new chemicals that are being introduced into ambient receiving waters. We propose a tiered framework that incorporates bioanalytical screening tools and diagnostic nontargeted chemical analysis to more effectively monitor for contaminants of emerging concern (CECs). The framework is based on a comprehensive battery of in vitro bioassays to first screen for a broad spectrum of CECs and nontargeted analytical methods to identify bioactive contaminants missed by the currently favored targeted analyses. Water quality managers in California have embraced this strategy with plans to further develop and test this framework in regional and statewide pilot studies on waterbodies that receive discharge from municipal wastewater treatment plants and stormwater runoff. In addition to directly informing decisions, the data obtained using this framework can be used to construct and validate models that better predict CEC occurrence and toxicity. The adaptive interplay among screening results, diagnostic assessment and predictive modeling will allow managers to make decisions based on the most current and relevant information, instead of extrapolating from parameters with questionable linkage to CEC impacts.

    Hardham, J M; Lamichhane, C M

    2013-01-01

    Veterinary diagnostic products generated ~$3 billion US dollars in global sales in 2010. This industry is poised to undergo tremendous changes in the next decade as technological advances move diagnostic products from the traditional laboratory-based and handheld immunologic assays towards highly technical, point of care devices with increased sensitivity, specificity, and complexity. Despite these opportunities for advancing diagnostic products, the industry continues to face numerous challenges in developing diagnostic products for emerging and foreign animal diseases. Because of the need to deliver a return on the investment, research and development dollars continue to be focused on infectious diseases that have a negative impact on current domestic herd health, production systems, or companion animal health. Overcoming the administrative, legal, fiscal, and technological barriers to provide veterinary diagnostic products for the National Veterinary Stockpile will reduce the threat of natural or intentional spread of foreign diseases and increase the security of the food supply in the US.

    2010-01-01

    Full Text Available Disaster scenarios are dismal and often result in mass displacement and migration of people. In eventuality of emergency situations, people need to be rehabilitated and provided with an adequate supply of drinking water, the most essential natural resource needed for survival, which is often not easily available even during non-disaster periods. In the aftermath of a natural or human-made disaster affecting mankind and livestock, the prime aim is to ensure supply of safe water to reduce the occurrence and spread of water borne disease due to interrupted, poor and polluted water supply. Chemical, biological, radiological and nuclear (CBRN emergencies augment the dilemma as an additional risk of "contamination" is added. The associated risks posed to health and life should be reduced to as low as reasonably achievable. Maintaining a high level of preparedness is the crux of quick relief and efficient response to ensure continuous supply of safe water, enabling survival and sustenance. The underlying objective would be to educate and train the persons concerned to lay down the procedures for the detection, cleaning, and treatment, purification including desalination, disinfection, and decontamination of water. The basic information to influence the organization of preparedness and execution of relief measures at all levels while maintaining minimum standards in water management at the place of disaster, are discussed in this article.

    International Nuclear Information System (INIS)

    In response to the end of the Cold War and changes in the world's political regimes, the United States is not producing new-design nuclear weapons. Instead, the emphasis on the U.S. nuclear weapons program is on reducing the size of the Nation's nuclear stockpile by dismantling existing nuclear weapons. The Department of Energy (DOE) has been directed by the President and Congress to maintain the safety and reliability of the reduced nuclear weapons stockpile in the absence of underground nuclear testing. In order to fulfill that responsibility, DOE has developed a Stockpile Stewardship and Management Program to provide a single highly integrated program for maintaining the continued safety and reliability of the nuclear stockpile.

    2016-03-01

    This year’s summary report updates the Fiscal Year 2016 Stockpile Stewardship and Management Plan (FY 2016 SSMP), the 25-year strategic program of record that captures the plans developed across numerous NNSA programs and organizations to maintain and modernize the scientific tools, capabilities, and infrastructure necessary to ensure the success of NNSA’s nuclear weapons mission. The SSMP is a companion to the Prevent, Counter, and Respond: A Strategic Plan to Reduce Global Nuclear Threats (FY 2017-2021) report, the planning document for NNSA’s nuclear threat reduction mission. New versions of both reports are published each year in response to new requirements and challenges. Much was accomplished in FY 2015 as part of the program of record described in this year’s SSMP. The science-based Stockpile Stewardship Program allowed the Secretaries of Energy and Defense to certify for the twentieth time that the stockpile remains safe, secure, and effective without the need for underground nuclear explosive testing. The talented scientists, engineers, and technicians at the three national security laboratories, the four nuclear weapons production plants, and the national security site are primarily responsible for this continued success. Research, development, test, and evaluation programs have advanced NNSA’s understanding of weapons physics, component aging, and material properties through first-of-a-kind shock physics experiments, along with numerous other critical experiments conducted throughout the nuclear security enterprise. The multiple life extension programs (LEPs) that are under way made progress toward their first production unit dates. The W76-1 LEP is past the halfway point in total production, and the B61-12 completed three development flight tests. Critical to this success is the budget. The Administration’s budget request for NNSA’s Weapons Activities has increased for all but one of the past seven years, resulting in a total increase of

    Full Text Available Lake Orta, located in Piedmont, northwestern Italy, has been severely affected by industrial pollution since the 1930s. A successful liming intervention, performed in 1988-1990, returned pH levels in the lake to neutrality, and accelerated the reduction of aqueous trace metal concentrations. In this paper, we present an update knowledge of the chemical status of Lake Orta, focusing on the data collected from 1990 to 2014. In this period we sampled the lake at its deepest point (Qualba station, on a monthly (1990-2000 or seasonal (since 2001 basis. Samples were collected at nine depths through the water column, and analyzed for pH, conductivity, alkalinity, major ions, nutrients, and trace metals. Collectively, these data allowed us to evaluate the long-term response of the lake to the restoration treatment, with particular regard to its acid-base status; they also provided insights into emerging or potential critical issues, including eutrophication and re-suspension of trace metals that still linger in the lake. Furthermore, the evaluation of the present chemical condition of the lake is a precondition for any successive restoration measure, such as fish introduction. The recent data confirmed the lake’s water quality has recovered, i.e. returned to a pre-pollution chemical state. Lake water values of pH and concentrations of ammonium, sulphate and base cations have stabilized. Alkalinity and nitrate concentrations are also expected to reach stable level in the next few years. Levels of nitrate, reactive silica, and phosphorus compounds are now regulated by algal uptake, providing indirect evidence of a partial biological recovery. For instance, both the inter-annual average decline and the reappearance of a seasonal signal in silica confirmed the presence of a stable diatom community. The lake is presently oligotrophic, and concentrations of both N and P compounds are steady and low throughout the year. However, a monthly check of nutrient

    This thesis describes the synthesis of carbohydrate-based chemical probes to either profile glucosidases, or specifically label the emerging cancer marker galectin-3 in cell lysates. In general, chemical probe based methods can tag certain classes of proteins, and covalently label a protein or a protein family. This method should allow quantification within a mixture of other proteins. It could also give information about the localization of the protein in the cell, and about interactions of ...

    In this paper and Paper II, we outline a general framework for the thermodynamic description of open chemical reaction networks, with special regard to metabolic networks regulating cellular physiology and biochemical functions. We first introduce closed networks "in a box", whose thermodynamics is subjected to strict physical constraints: the mass-action law, elementarity of processes, and detailed balance. We further digress on the role of solvents and on the seemingly unacknowledged property of network independence of free energy landscapes. We then open the system by assuming that the concentrations of certain substrate species (the chemostats) are fixed, whether because promptly regulated by the environment via contact with reservoirs, or because nearly constant in a time window. As a result, the system is driven out of equilibrium. A rich algebraic and topological structure ensues in the network of internal species: Emergent irreversible cycles are associated with nonvanishing affinities, whose symmetries are dictated by the breakage of conservation laws. These central results are resumed in the relation a + b = s(Y) between the number of fundamental affinities a, that of broken conservation laws b and the number of chemostats s(Y). We decompose the steady state entropy production rate in terms of fundamental fluxes and affinities in the spirit of Schnakenberg's theory of network thermodynamics, paving the way for the forthcoming treatment of the linear regime, of efficiency and tight coupling, of free energy transduction, and of thermodynamic constraints for network reconstruction.

  3. Final Programmatic Environmental Impact Statement for stockpile stewardship and management: Volume 3

    International Nuclear Information System (INIS)

    The Department of Energy (DOE) has been directed by the President and Congress to maintain the safety and reliability of the reduced nuclear weapons stockpile in the absence of underground nuclear testing. In order to fulfill that responsibility, DOE has developed a Stockpile Stewardship and Management Program to provide a single highly integrated technical program for maintaining the continued safety and reliability of the nuclear stockpile. The Stockpile Stewardship and Management Programmatic Environmental Impact Statement (PEIS) describes and analyzes alternative ways to implement the proposed actions for the Stockpile Stewardship and Management Program. This document consists of Volume III, Appendix I entitled ''National Ignition Facility Project-Specific Analysis,'' which investigates the environmental impacts resulting from constructing and operating the proposed National Ignition Facility

    Emergency planning for an unintended release of chemical agent from the nation`s chemical weapons stockpile should include preparation for. the period following implementation of immediate emergency response. That period -- the recovery, reentry, and restoration stage -- is the subject of this report. The report provides an overview of the role of recovery, reentry, and restoration planning in the Chemical Stockpile Emergency Preparedness Program (CSEPP), describes the transition from immediate emergency response to restoration, and analyzes the legal framework that would govern restoration activities. Social, economic, and administrative issues, as well as technical ones, need to be considered in the planning effort. Because of possible jurisdictional conflicts, appropriate federal, state, and local agencies need to be included in a coordinated planning process. Advance consideration should be given to the pertinent federal and state statutes and regulations. On the federal level, the principal statutes and regulations to be considered are those associated with the Comprehensive Environmental Response, Compensation, and Liability Act; the Resource Conservation and Recovery Act; and the National Environmental Policy Act. This report recommends that extensive preaccident planning be undertaken for the recovery, reentry, and restoration stage and outlines several key issues that should be considered in that planning. The need for interagency cooperation and coordination at all levels of the planning process is emphasized.

  5. The occurrence of emerging trace organic chemicals in wastewater effluents in Saudi Arabia

    2014-04-01

    Emerging trace organic chemicals (TOrCs) released into the environment via discharge of wastewater effluents have been detected in rivers and lakes worldwide, raising concerns due to their potential persistence, toxicity and bioaccumulation. This study provides the first reconnaissance of TOrC occurrence in wastewater effluents within Saudi Arabia. Four wastewater treatment plants (WWTPs 1-4) located in Western Saudi Arabia were sampled hourly over twelve-hour periods, for a total of six sampling events. All samples were analyzed for a wide range of TOrC encompassing pharmaceuticals, personal care products and household chemicals. Treatment and capacities of the plants varied from non-nitrifying to full biological nutrient removal providing a representative cross section of different types of plants operational within the country. A comparison of TOrC occurrence in effluents in Saudi Arabia with respective effluent qualities in the United States revealed similar levels for most TOrC. Overall, the occurrence of TOrC was higher at two of the plants. The higher TOrC concentrations at WWTP 1 are likely due to the non-nitrifying biological treatment process. The unique TOrC occurrence observed in the WWTP 3 effluent was unlike any other plant and was attributed to the influence of a large number of international visitors in its sewershed. The occurrence of TOrC in this plant was not expected to be representative of the occurrence elsewhere in the country. Bimodal diurnal variation expected for a range of TOrC was not observed, though some hourly variation in TOrC loading was noted for WWTP 3. Since water reclamation and reuse have received increasing interest in Saudi Arabia within the last few years, results from this study provide a good foundation in deciding whether advanced treatment is necessary to attenuate TOrC deemed to be of concern in effluents, or if natural treatment such as managed aquifer recharge provides sufficient protection to public health. © 2014

    I would like to start by working from Vic Reis`s total quality management diagram in which he began with the strategy and then worked through the customer requirements-what the Department of Defense (DoD) is hoping for from the science-based stockpile stewardship program. Maybe our customer`s requirements will help guide some of the issues that we should be working on. ONe quick answer to {open_quotes}why have we adopted a science-based strategy{close_quotes} is that nuclear weapons are a 50-year responsibility, not just a 5-year responsibility, and stewardship without testing is a grand challenge. While we can do engineering maintenance and turn over and remake a few things on the short time scale, without nuclear testing, without new weapons development, and without much of the manufacturing base that we had in the past, we need to learn better just how these weapons are actually working.

  7. Hydroxocobalamin as a Cyanide Antidote: Empirical use , Safety, Efficacy, and Considerations for Stockpiling

    International Nuclear Information System (INIS)

    Cyanide is a well-known toxic terrorism agent and is a major cause of mortality and morbidity in smoke inhalation victims. Terrorist attacks could start enclosed-space fires with cyanide-poisoned victims, even if cyanide itself was not utilized. Cyanide poisoning cannot be emergent confirmed by laboratory analysis and treatment with safe and efficacious antidotes must be administered empirically. Hydroxocobalamin has been recently approved by the US FDA and is a safe and efficacious antidote. Its efficacy is comparable to that of other, more toxic, cyanide antidotes. Its mechanism of action involves both direct cyanide chelation (forming non-toxic cyanocobalamin which is excreted in the urine) and nitric oxide scavenging. Adverse effects are usually limited to transient dark red-brown discoloration of urine, skin, sclera, and mucous membranes. Antidotal doses have not caused allergic reactions in cyanide-poisoned patients and only minor and easily-treated allergic reactions occurred in 2 of 136 normal volunteers. Transient, asymptomatic hypertension and reflex bradycardia have occurred in some normal volunteers, but not in seriously ill smoke inhalation victims not having significant cyanide poisoning. Hydroxocobalamin is a safe and efficacious antidote and can be empirically administered in pre-hospital or emergency department settings. It is therefore suitable for inclusion in national or multinational medication stockpiles and is already included in some national programs in the European Union.(author)

    2014-03-11

    This research program explored the efficacy of using molecular-level manipulation, imaging and scanning tunneling spectroscopy in conjunction with supersonic molecular beam gas-surface scattering to significantly enhance our understanding of chemical processes occurring on well-characterized interfaces. One program focus was on the spatially-resolved emergent behavior of complex reaction systems as a function of the local geometry and density of adsorbate-substrate systems under reaction conditions. Another focus was on elucidating the emergent electronic and related reactivity characteristics of intentionally constructed single and multicomponent atom- and nanoparticle-based materials. We also examined emergent chirality and self-organization in adsorbed molecular systems where collective interactions between adsorbates and the supporting interface lead to spatial symmetry breaking. In many of these studies we combined the advantages of scanning tunneling (STM) and atomic force (AFM) imaging, scanning tunneling local electronic spectroscopy (STS), and reactive supersonic molecular beams to elucidate precise details of interfacial reactivity that had not been observed by more traditional surface science methods. Using these methods, it was possible to examine, for example, the differential reactivity of molecules adsorbed at different bonding sites in conjunction with how reactivity is modified by the local configuration of nearby adsorbates. At the core of this effort was the goal of significantly extending our understanding of interfacial atomic-scale interactions to create, with intent, molecular assemblies and materials with advanced chemical and physical properties. This ambitious program addressed several key topics in DOE Grand Challenge Science, including emergent chemical and physical properties in condensed phase systems, novel uses of chemical imaging, and the development of advanced reactivity concepts in combustion and catalysis including carbon

  11. Diphoterine for emergent eye/skin chemical splash decontamination: a review.

    Science.gov (United States)

    Hall, Alan H; Blomet, Joel; Mathieu, Laurence

    2002-08-01

    Eye/skin chemical splashes are a significant problem. Diphoterine is an hypertonic, polyvalent, amphoteric compound developed in France as an eye/skin chemical splash water-based decontamination solution. In vitro and in vivo, it actively decontaminates approximately 600 chemicals, including acids, alkalis, oxidizing and reducing agents, irritants, lacrimators, solvents, alkylating agents, and radionuclides. Its chemical bond energy for such agents is greater than that of tissue receptors. Its hypertonicity impedes chemical tissue penetration and may remove some amount of skin/cornea-absorbed toxicants not already bound to tissue receptors. Diphoterine chemical reactions are not exothermic. Diphoterine and its acid/alkali decontamination residues are not irritating to the eyes or skin; it is essentially nontoxic. Diphoterine can prevent eye/skin burns following chemical splashes and results in nearly immediate pain relief. PMID:12136973

  13. Designing monitoring programs for chemicals of emerging concern in potable reuse ⋯ What to include and what not to include?

    KAUST Repository

    2012-11-01

    This study discussed a proposed process to prioritize chemicals for reclaimed water monitoring programs, selection of analytical methods required for their quantification, toxicological relevance of chemicals of emerging concern regarding human health, and related issues. Given that thousands of chemicals are potentially present in reclaimed water and that information about those chemicals is rapidly evolving, a transparent, science-based framework was developed to guide prioritization of which compounds of emerging concern (CECs) should be included in reclaimed water monitoring programs. The recommended framework includes four steps: (1) compile environmental concentrations (e.g., measured environmental concentration or MEC) of CECs in the source water for reuse projects; (2) develop a monitoring trigger level (MTL) for each of these compounds (or groups thereof) based on toxicological relevance; (3) compare the environmental concentration (e.g., MEC) to the MTL; CECs with a MEC/MTL ratio greater than 1 should be prioritized for monitoring, compounds with a ratio less than \\'1\\' should only be considered if they represent viable treatment process performance indicators; and (4) screen the priority list to ensure that a commercially available robust analytical method is available for that compound. © IWA Publishing 2013.

  15. Evaluating legacy contaminants and emerging chemicals in marine environments using adverse outcome pathways and biological effects-directed analysis

    International Nuclear Information System (INIS)

    Natural and synthetic chemicals are essential to our daily lives, food supplies, health care, industries and safe sanitation. At the same time protecting marine ecosystems and seafood resources from the adverse effects of chemical contaminants remains an important issue. Since the 1970s, monitoring of persistent, bioaccumulative and toxic (PBT) chemicals using analytical chemistry has provided important spatial and temporal trend data in three important contexts; relating to human health protection from seafood contamination, addressing threats to marine top predators and finally providing essential evidence to better protect the biodiversity of commercial and non-commercial marine species. A number of regional conventions have led to controls on certain PBT chemicals over several years (termed ‘legacy contaminants’; e.g. cadmium, lindane, polycyclic aromatic hydrocarbons [PAHs] and polychlorinated biphenyls [PCBs]). Analytical chemistry plays a key role in evaluating to what extent such regulatory steps have been effective in leading to reduced emissions of these legacy contaminants into marine environments. In parallel, the application of biomarkers (e.g. DNA adducts, CYP1A-EROD, vitellogenin) and bioassays integrated with analytical chemistry has strengthened the evidence base to support an ecosystem approach to manage marine pollution problems. In recent years, however, the increased sensitivity of analytical chemistry, toxicity alerts and wider environmental awareness has led to a focus on emerging chemical contaminants (defined as chemicals that have been detected in the environment, but which are currently not included in regulatory monitoring programmes and whose fate and biological impacts are poorly understood). It is also known that natural chemicals (e.g. algal biotoxins) may also pose a threat to marine species and seafood quality. Hence complex mixtures of legacy contaminants, emerging chemicals and natural biotoxins in marine ecosystems represent

  17. Construction of a technique plan repository and evaluation system based on AHP group decision-making for emergency treatment and disposal in chemical pollution accidents

    International Nuclear Information System (INIS)

    Highlights: • Different chemical pollution accidents were simplified using the event tree analysis. • Emergency disposal technique plan repository of chemicals accidents was constructed. • The technique evaluation index system of chemicals accidents disposal was developed. • A combination of group decision and analytical hierarchy process (AHP) was employed. • Group decision introducing similarity and diversity factor was used for data analysis. - Abstract: The environmental pollution resulting from chemical accidents has caused increasingly serious concerns. Therefore, it is very important to be able to determine in advance the appropriate emergency treatment and disposal technology for different types of chemical accidents. However, the formulation of an emergency plan for chemical pollution accidents is considerably difficult due to the substantial uncertainty and complexity of such accidents. This paper explains how the event tree method was used to create 54 different scenarios for chemical pollution accidents, based on the polluted medium, dangerous characteristics and properties of chemicals involved. For each type of chemical accident, feasible emergency treatment and disposal technology schemes were established, considering the areas of pollution source control, pollutant non-proliferation, contaminant elimination and waste disposal. Meanwhile, in order to obtain the optimum emergency disposal technology schemes as soon as the chemical pollution accident occurs from the plan repository, the technique evaluation index system was developed based on group decision-improved analytical hierarchy process (AHP), and has been tested by using a sudden aniline pollution accident that occurred in a river in December 2012

  18. Innovative Concepts and Operational Techniques for the Strategic National Stockpile

    International Nuclear Information System (INIS)

    This presentation is to discuss the innovative concepts and operational techniques developed by the Center for Disease Control and Prevention's Division of Strategic National Stockpile (DSNS). The primary response model for the SNS is to move from secure strategic storage locations to an area of need within 12 hours to augment local resources. While this 12 hour response is appropriate for most threat scenarios, it clearly cannot meet the needs of first line responders who need to rapidly administer initial dosing of nerve agent antidote. To address the threat of nerve agent poisoning the DSNS developed the CHEMPACK Project which allows centralized SNS management forward placement within hundreds of local jurisdictions. Another variation from the primary mission of the DSNS is addressing the nation's potential shortfall in non-acute care bed capacity. To address this mission, the Federal Medical Station (FMS) program was created to build surge capability to meet a range of non-acute medical needs following a disaster. The FMS model is a pre-configured 250 bed unit that is deployable throughout the Nation and configured to respond rapidly. Operational techniques used to maximize product lifespan and efficacy will also be discussed.(author)

    2016-07-01

    Managing the dynamics of vaccine supply and demand represents a significant challenge with very high stakes. Insufficient vaccine supplies can necessitate rationing, lead to preventable adverse health outcomes, delay the achievements of elimination or eradication goals, and/or pose reputation risks for public health authorities and/or manufacturers. This article explores the dynamics of global vaccine supply and demand to consider the opportunities to develop and maintain optimal global vaccine stockpiles for universal vaccines, characterized by large global demand (for which we use measles vaccines as an example), and nonuniversal (including new and niche) vaccines (for which we use oral cholera vaccine as an example). We contrast our approach with other vaccine stockpile optimization frameworks previously developed for the United States pediatric vaccine stockpile to address disruptions in supply and global emergency response vaccine stockpiles to provide on-demand vaccines for use in outbreaks. For measles vaccine, we explore the complexity that arises due to different formulations and presentations of vaccines, consideration of rubella, and the context of regional elimination goals. We conclude that global health policy leaders and stakeholders should procure and maintain appropriate global vaccine rotating stocks for measles and rubella vaccine now to support current regional elimination goals, and should probably also do so for other vaccines to help prevent and control endemic or epidemic diseases. This work suggests the need to better model global vaccine supplies to improve efficiency in the vaccine supply chain, ensure adequate supplies to support elimination and eradication initiatives, and support progress toward the goals of the Global Vaccine Action Plan.

    The Kami-goto oil stockpiling base located in Kami-nakadori Island in Nagasaki Prefecture is the world`s first off-shore oil stockpiling base. This paper introduces its summary including natural features of the area. Beginning with the first feasibility study in 1978, the site selection was decided in 1981, and Kami-goto Oil Stockpiling Co., Ltd. was established in the following year. The construction has begun in 1984 and was completed as an off-shore base with an oil stockpiling capacity of 4.4 million kilo-liters. The base consists of five oil stockpiling ships each with stockpiling capacity of 880,000 kilo-liters, their mooring facilities, breakwaters built on west and north sides of the base to prevent waves coming into the ship anchoring area, a sea berth for large oil tankers, and ground facilities to manage and operate the base. The base has a land area of 26 ha and a sea area of 40 ha. The base is largely characterized in that the land area is smaller, thus damaging little natural environment in the area, and less affected by earthquakes. The sea berth is capable of mooring a 300,000 DWT crude oil tanker. 4 figs., 2 tabs.

    Full Text Available Marine chemical ecology comprises the study of the production and interaction of bioactive molecules affecting organism behavior and function. Here we focus on bioactive compounds and interactions associated with phytoplankton, particularly bloom-forming diatoms, prymnesiophytes and dinoflagellates. Planktonic bioactive metabolites are structurally and functionally diverse and some may have multiple simultaneous functions including roles in chemical defense (antipredator, allelopathic and antibacterial compounds, and/or cell-to-cell signaling (e.g., polyunsaturated aldehydes (PUAs of diatoms. Among inducible chemical defenses in response to grazing, there is high species-specific variability in the effects on grazers, ranging from severe physical incapacitation and/or death to no apparent physiological response, depending on predator susceptibility and detoxification capability. Most bioactive compounds are present in very low concentrations, in both the producing organism and the surrounding aqueous medium. Furthermore, bioactivity may be subject to synergistic interactions with other natural and anthropogenic environmental toxicants. Most, if not all phycotoxins are classic secondary metabolites, but many other bioactive metabolites are simple molecules derived from primary metabolism (e.g., PUAs in diatoms, dimethylsulfoniopropionate (DMSP in prymnesiophytes. Producing cells do not seem to suffer physiological impact due to their synthesis. Functional genome sequence data and gene expression analysis will provide insights into regulatory and metabolic pathways in producer organisms, as well as identification of mechanisms of action in target organisms. Understanding chemical ecological responses to environmental triggers and chemically-mediated species interactions will help define crucial chemical and molecular processes that help maintain biodiversity and ecosystem functionality.

  7. 1997 toxic chemical release inventory. Emergency Planning and Community Right-To-Know Act, Section 313

    International Nuclear Information System (INIS)

    Two listed toxic chemicals were used at the Hanford Site above established activity thresholds: phosphoric acid and chlorine. Because total combined quantities of chlorine released, disposed, treated, recovered through recycle operations, co-combusted for energy recovery, and transferred to off-site locations for the purpose of recycle, energy recovery, treatment, and/or disposal, amounted to less than 500 pounds, the Hanford Site qualified for the alternate one million pound threshold for chlorine. Accordingly, this Toxic Chemical Release Inventory includes a Form A for chlorine, and a Form B for phosphoric acid

    The maintenance and security of nuclear weapons in the stockpile involves decisions based on risk analysis and quantitative measures of risk. Risk is a factor in all decisions, a particularly important factor in decisions of a large scale. One example of high-risk decisions we will discuss is the risk involved in design diversity within the stockpile of nuclear weapons arsenal. Risk is defined as 'possibility of loss or injury' and the 'degree of probability of such loss' (Kaplan and Garrick 12). To introduce the risk involved with maintaining the weapons stockpile we will draw a parallel to the design and maintenance of Southwest Airlines fleet of Boeing 737 planes. The clear benefits for cost savings in maintenance of having a uniform fleet are what historically drove Southwest to have only Boeing 737s in their fleet. Less money and resources are need for maintenance, training, and materials. Naturally, risk accompanies those benefits. A defect in a part of the plane indicates a potential defect in that same part in all the planes of the fleet. As a result, safety, business, and credibility are at risk. How much variety or diversity does the fleet need to mitigate that risk? With that question in mind, a balance is needed to accommodate the different risks and benefits of the situation. In a similar way, risk is analyzed for the design and maintenance of nuclear weapons in the stockpile. In conclusion, risk must be as low as possible when it comes to the nuclear weapons stockpile. Design and care to keep the stockpile healthy involves all aspects of risk management. Design diversity is a method that helps to mitigate risk, and to help balance options in stockpile stewardship.

    To address oil spillage and chemical leakage accidents, the development of efficient sorbent materials is of global importance for environment and water source protection. Here we report on a new type of carbon nanofiber (CNF) aerogels as efficient sorbents for oil uptake with high sorption capacity and excellent recyclability. Importantly, the oil uptake ability of the CNF aerogels can be maintained over a wide temperature range, from liquid nitrogen temperature up to ca. 400°C, making them ...

  11. 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.

    The Surface PARTiculate mAtter Network (SPARTAN) is a long-term project that includes characterization of chemical and physical attributes of aerosols from filter samples collected worldwide. This paper discusses the ongoing efforts of SPARTAN to define and quantify major ions and trace metals found in fine particulate matter (PM2.5). Our methods infer the spatial and temporal variability of PM2.5 in a cost-effective manner. Gravimetrically weighed filters represent multi-day averages of PM2.5, with a collocated nephelometer sampling air continuously. SPARTAN instruments are paired with AErosol RObotic NETwork (AERONET) sun photometers to better understand the relationship between ground-level PM2.5 and columnar aerosol optical depth (AOD).We have examined the chemical composition of PM2.5 at 12 globally dispersed, densely populated urban locations and a site at Mammoth Cave (US) National Park used as a background comparison. So far, each SPARTAN location has been active between the years 2013 and 2016 over periods of 2-26 months, with an average period of 12 months per site. These sites have collectively gathered over 10 years of quality aerosol data. The major PM2.5 constituents across all sites (relative contribution ± SD) are ammoniated sulfate (20 % ± 11 %), crustal material (13.4 % ± 9.9 %), equivalent black carbon (11.9 % ± 8.4 %), ammonium nitrate (4.7 % ± 3.0 %), sea salt (2.3 % ± 1.6 %), trace element oxides (1.0 % ± 1.1 %), water (7.2 % ± 3.3 %) at 35 % RH, and residual matter (40 % ± 24 %).Analysis of filter samples reveals that several PM2.5 chemical components varied by more than an order of magnitude between sites. Ammoniated sulfate ranges from 1.1 µg m-3 (Buenos Aires, Argentina) to 17 µg m-3 (Kanpur, India in the dry season). Ammonium nitrate ranged from 0.2 µg m-3 (Mammoth Cave, in summer) to 6.8 µg m-3 (Kanpur, dry season). Equivalent black carbon ranged from 0.7 µg m-3 (Mammoth Cave) to over 8 µg m-3 (Dhaka, Bangladesh and Kanpur

    The interim guidance issued by the World Health Organization during the West Africa 2014 Ebola outbreak provides guidelines on the use of convalescent blood from Ebola survivors for transfusion therapy. Here we develop a novel mathematical model, based on the interim guidance, to examine the nonlinear transmission-treatment-donation-stockpile dynamics during an Ebola outbreak and with a large scale use of the transfusion therapy in the population. We estimate the reduction of case fatality ratio by introducing convalescent blood transfusion as a therapy, and inform optimal treatment-donation-stockpile strategies to balance the treatment need for case fatality ratio reduction and the strategic need of maintaining a minimal blood bank stockpile for other control priorities.

    In the preceding paper of this series (Part I [P. Nicolini and D. Frezzato, J. Chem. Phys. 138, 234101 (2013)]) we have unveiled some ubiquitous features encoded in the systems of polynomial differential equations normally applied in the description of homogeneous and isothermal chemical kinetics (mass-action law). Here we proceed by investigating a deeply related feature: the appearance of so-called slow manifolds (SMs) which are low-dimensional hyper-surfaces in the neighborhood of which the slow evolution of the reacting system occurs after an initial fast transient. Indeed a geometrical definition of SM, devoid of subjectivity, "naturally" follows in terms of a specific sub-dimensional domain embedded in the peculiar region of the concentrations phase-space that in Part I we termed as "attractiveness region." Numerical inspections on simple low-dimensional model cases are presented, including the benchmark case of Davis and Skodje [J. Chem. Phys. 111, 859 (1999)] and the preliminary analysis of a simplified model mechanism of hydrogen combustion. PMID:23802946

    The aim of this project is to research the applicability of wooden materials for protection of milled peat stockpile against losses during storaging. Water transmission features of sawdust, wastewood chip and whole tree chip were investigated in laboratory with raining experiments. The plan for raining experiments was made with experiment planning program and results were analysed with multivariate analysis. Freezing features were investigated thorough breaking tests with hydraulic piston vice. Laboratory experiments were completed with field tests in Laakasuo near Sotkamo. On the basis of results covering peat stockpiles with sawdust is fully competitive comparing to present covering methods. Chip materials are technically not as good covering materials as sawdust

  16. U.S. Nuclear Weapons Modernization - the Stockpile Life Extension Program

    Cook, Donald

    2016-03-01

    Underground nuclear testing of U.S. nuclear weapons was halted by President George H.W. Bush in 1992 when he announced a moratorium. In 1993, the moratorium was extended by President Bill Clinton and, in 1995, a program of Stockpile Stewardship was put in its place. In 1996, President Clinton signed the Comprehensive Nuclear Test Ban Treaty (CTBT). Twenty years have passed since then. Over the same time, the average age of a nuclear weapon in the stockpile has increased from 6 years (1992) to nearly 29 years (2015). At its inception, achievement of the objectives of the Stockpile Stewardship Program (SSP) appeared possible but very difficult. The cost to design and construct several large facilities for precision experimentation in hydrodynamics and high energy density physics was large. The practical steps needed to move from computational platforms of less than 100 Mflops/sec to 10 Teraflops/sec and beyond were unknown. Today, most of the required facilities for SSP are in place and computational speed has been increased by more than six orders of magnitude. These, and the physicists and engineers in the complex of labs and plants within the National Nuclear Security Administration (NNSA) who put them in place, have been the basis for underpinning an annual decision, made by the weapons lab directors for each of the past 20 years, that resort to underground nuclear testing is not needed for maintaining confidence in the safety and reliability of the U.S stockpile. A key part of that decision has been annual assessment of the physical changes in stockpiled weapons. These weapons, quite simply, are systems that invariably and unstoppably age in the internal weapon environment of radioactive materials and complex interfaces of highly dissimilar organic and inorganic materials. Without an ongoing program to rebuild some components and replace other components to increase safety or security, i.e., life extending these weapons, either underground testing would again be

    Gray mold, caused by the fungal pathogen Botrytis cinerea, is one of the most destructive diseases of small fruit crops and control is largely dependent on the application of fungicides. As part of a region-wide resistance-monitoring program that investigated 1,890 B. cinerea isolates from 189 fields in 10 states of the United States, we identified seven isolates (0.4%) from five locations in four different states with unprecedented resistance to all seven Fungicide Resistance Action Committee (FRAC) codes with single-site modes of action including FRAC 1, 2, 7, 9, 11, 12, and 17 registered in the United States for gray mold control. Resistance to thiophanate-methyl, iprodione, boscalid, pyraclostrobin, and fenhexamid was based on target gene mutations that conferred E198A and F200Y in β-tubulin, I365N/S in Bos1, H272R/Y in SdhB, G143A in Cytb, and T63I and F412S in Erg27. Isolates were grouped into MDR1 and MDR1h phenotypes based on sensitivity to fludioxonil and variations in transcription factor mrr1. MDR1h isolates had a previously described 3-bp deletion at position 497 in mrr1. Expression of ABC transporter atrB was increased in MDR1 isolates but highest in MDR1h isolates. None of the isolates with seven single resistances (SR) had identical nucleotide variations in target genes, indicating that they emerged independently. Multifungicide resistance phenotypes did not exhibit significant fitness penalties for the parameters used in this study, but MDR1h isolates produced more sclerotia at low temperatures and exhibited increased sensitivity to salt stress. In this study we show that current resistance management strategies have not been able to prevent the geographically independent development of resistance to all seven site-specific fungicides currently registered for gray mold control in the United States and document the presence of MDR1h in North America.

    Needle and syringe program (NSP) coverage is commonly used to assess NSP effectiveness. However, existing measures don't capture whether persons who inject drugs (PWIDs) stockpile syringes, an important and novel aspect of NSP coverage. In this study, we determine the extent of stockpiling in a sample of Australian PWIDs and assess whether including stockpiling enhances NSP coverage measures. As part of the Illicit Drug Reporting System study, PWIDs reported syringes procured and given away, total injections in the last month, and syringes currently stockpiled in 2014. We calculated NSP coverage with and without stockpiling to determine proportional change in adequate NSP coverage. We conducted receiver operating characteristic curve analysis to determine whether inclusion of stockpiled syringes in the measure improved sensitivity in discriminating cases and noncases of risky behaviors. Three-quarters of the sample reported syringe stockpiling, and stockpiling was positively associated with nonindigenous background, stable accommodation, no prison history, longer injecting careers, and more frequent injecting. Compared with previous measures, our measure was significantly better at discriminating cases of risky behaviors. Our results could inform NSP policy to loosen restricted-exchange practice, allowing PWIDs greater flexibility in syringe procurement practices, promoting greater NSP coverage, and reducing PWIDs' engagement in risky behaviors.

  19. Some considerations of the fuel stockpile on the security of energy for thermal and nuclear power plants in Japan

    International Nuclear Information System (INIS)

    By estimating the fuel stockpile for thermal and nuclear power plants, the external costs of the energy security have been calculated. The stockpiles for these power plants are: 32.85 million kilo liters of oil, 3.60 million tons of coal, 2.61 million tons of LNG, and 2892 tons of nuclear fuel, which is contained in the nuclear reactors, the quantity being equivalent to 3 years in the equilibrium cycle. The external costs for the fuel stockpile per year have been estimated at -0.028, -0.090, -0.086, and -4.43 yen/kWh respectively. The fuel stockpile for nuclear power plants contained in the reactors have been to be calculated to be equal to 435 days worth of crude oil. (The amount totals to 580 days worth of the oil, if the stockpile in the fabrication plants was added.) (author)

    The Federal Emergency Management Information System (FEMIS) is an emergency management planning and analysis tool that was developed by the Pacific Northwest National Laboratory (PNNL) under the direction of the US Army Chemical Biological Defense Command. The FEMIS System Administration Guide defines FEMIS hardware and software requirements and gives instructions for installing the FEMIS software package. This document also contains information on the following: software installation for the FEMIS data servers, communication server, mail server, and the emergency management workstations; distribution media loading and FEMIS installation validation and troubleshooting; and system management of FEMIS users, login privileges, and usage. The system administration utilities (tools), available in the FEMIS client software, are described for user accounts and site profile. This document also describes the installation and use of system and database administration utilities that will assist in keeping the FEMIS system running in an operational environment. The FEMIS system is designed for a single Chemical Stockpile Emergency Preparedness Program (CSEPP) site that has multiple Emergency Operations Centers (EOCs). Each EOC has personal computers (PCs) that emergency planners and operations personnel use to do their jobs. These PCs are connected via a local area network (LAN) to servers that provide EOC-wide services. Each EOC is interconnected to other EOCs via telecommunications links.

    An analysis of the scientific areas in High Energy Density (HED) physics that underpin the enduring LANL mission in Stockpile Stewardship (SS) has identified important research needs that are not being met. That analysis has included the work done as part of defining the mission need for the High Intensity Laser Laboratory (HILL) LANL proposal to NNSA, LDRD DR proposal evaluations, and consideration of the Predictive Capability Framework and LANL NNSA milestones. From that evaluation, we have identified several specific and scientifically-exciting experimental concepts to address those needs. These experiments are particularly responsive to physics issues in Campaigns 1 and 10. These experiments are best done initially at the LANL Trident facility, often relying on the unique capabilities available there, although there are typically meritorious extensions envisioned at future facilities such as HILL, or the NIF once the ARC short-pulse laser is available at sufficient laser intensity. As the focus of the LANL HEDP effort broadens from ICF ignition of the point design at the conclusion of the National Ignition Campaign, into a more SS-centric effort, it is useful to consider these experiments, which address well-defined issues, with specific scientific hypothesis to test or models to validate or disprove, via unit-physics experiments. These experiments are in turn representative of a possible broad experimental portfolio to elucidate the physics of interest to these campaigns. These experiments, described below, include: (1) First direct measurement of the evolution of particulates in isochorically heated dense plasma; (2) Temperature relaxation measurements in a strongly-coupled plasma; (3) Viscosity measurements in a dense plasma; and (4) Ionic structure factors in a dense plasma. All these experiments address scientific topics of importance to our sponsors, involve excellent science at the boundaries of traditional fields, utilize unique capabilities at LANL

  11. A suggested approach to the selection of chemical and biological protective clothing--meeting industry and emergency response needs for protection against a variety of hazards.

    Science.gov (United States)

    Stull, Jeffrey O

    2004-01-01

    The paper describes the development of a comprehensive decision logic for selection and use of biological and chemical protective clothing (BCPC). The decision logic recognizes the separate areas of BCPC use among emergency, biological, and chemical hazards. The proposed decision logic provides a system for type classifying BCPC in terms of its compliance with existing standards (for emergency applications), the overall clothing integrity, and the material barrier performance. Type classification is offered for garments, gloves, footwear, and eye/face protection devices. On the basis of multiple, but simply designed flowcharts, the type of BCPC appropriate for specific biological and chemical hazards can be selected. The decision logic also provides supplemental considerations for choosing appropriate BCPC features. PMID:15377412

    1985-08-01

    Operation and specifications are reviewed for stackers and stacker-reclaimer series produced by TAKRAF in the GDR. The equipment is employed in open air coal and mineral stockpile facilities; its haulage capacity varies between 450 and 12,500 m/sup 3//h. Continuous haulage of bulk is based on belt conveyor systems with belt widths between 0.8 and 2.25 m; stacking booms are up to 40 m long. The combined stacker-reclaimer series operates with a reclaiming bucket wheel of 5600 m/sup 3//h maximum capacity. The performance of stockpile equipment series at large bulk handling harbors and at coal power plant storage yards is discussed.

  19. Evaluation of environmental effect of coal stockpile in Muara Telang, Banyuasin, Indonesia

    International Nuclear Information System (INIS)

    Stockpile commonly serves as a temporary dump before the coal is transported through the waterways. This study investigated the effects of coal stockpiles on the surrounding environment: air, water, and soil. The location of the study is in the estuary of Telang, South-Sumatra, Indonesia, which is located at the edge of the river of Telang and close to the residential community. The monitoring of the environmental impact from the stockpile is intended to conduct an environmental assessment owing the existence and operations of coal accumulation. Enviromental impact analysis was conducted based on the value of the effluent, air pollution (dust), soil and water by determining the parameters of the coal wastewater pH, total suspended solid, ferrous dan ferrous metals contents. The results indicate that the total suspended particulate, total suspended solids, noise level, ferrous metal and manganese metal were 10-14 μg/Nm3 249-355 mg/L, 41.3 to 50.3 dBA, 6.074 to7.579 mg/L, and 1.987 to 2.678 mg/L, respectively. Meanwhile the pH of water and soil were 3 to 4 and 2.83 to 4.02 respectively. It is concluded that the pH value are beyond the threshold standard.

  1. Environmental Hazard Assessment of Phosphogypsum Waste Stockpile Material from Jordan

    International Nuclear Information System (INIS)

    Phosphogypsum (PG) is a by-product of the chemical reaction called the 'wet process' whereby sulphuric acid is reacted with phosphate rock (PR) to produce phosphoric acid, needed for fertilizer production. Through the wet process, some impurities naturally present in the PR become incorporated in PG, including U decay-series radionuclides are the main important concern which could have an effect on the surrounding environment and prevent its safe utilization. In order to determine the distribution and bioavailability of radionuclides to the surrounding environment we used a sequential leaching of PG samples from Aqaba and Eshidiya Fertilizer industry. The results show that 226Ra and 210Pb radionuclides fractionate likely in PG, where percentages in the corresponding to PR of 85% of the 226Ra and 85% of the 210Pb were presented. The sequential extraction results exhibit that most of 226Ra and 210Pb are bound in the residual phase (non-CaSO4) fraction ranging from (45-65% and 55-75%) respectively, whereas only 10-15% and 10-20% respectively of these radionuclides are distributed in the most labile fraction. The results obtained from this study that radionuclides are not incorporated with gypsum itself and may not form a threat to the surrounding environment. (author)

    The Emergency Planning and Community Right-to-Know Act of 1986 (EPCIL4), Title III, Section 313 [also known as the Superfund Amendment and Reauthorization Act (SARA)], as modified by Executive Order 12856, requires all federal facilities to submit an annual Toxic Chemical Release Inventory report every July for the preceding calendar year. Owners and operators of manufacturing, processing, or production facilities are required to report their toxic chemical releases to all environmental mediums (air, water, soil, etc.). At Los Alamos National Laboratory (LANL), nitric acid was the only toxic chemical used in 1997 that met the reportable threshold limit of 10,000 lb. Form R is the only documentation required by the Environmental Protection Agency, and it is included in the appendix of this report. This report, as requested by DOE, is provided for documentation purposes. In addition, a detailed description of the evaluation and reporting process for chemicals and processes at LANL has been included.

This assumes no concurrent intervention strategies and no wastage due to non-influenza respiratory infections. A dynamic model can provide a mechanism to consider complex scenarios to support decisions regarding the optimal NAS size under uncertainty.We developed a dynamic model for pandemic influenza in Canada that is structured by age and risk to calculate the demand for antivirals to treat persons with pandemic influenza under a wide-range of scenarios that incorporated transmission dynamics, disease severity, and intervention strategies. The anticipated per capita number of acute respiratory infections due to viruses other than influenza was estimated for the full pandemic period from surveys based on criteria to identify potential respiratory infections.Our results demonstrate that up to two thirds of the population could develop respiratory symptoms as a result of infection with a pandemic strain. In the case of perfect antiviral allocation, up to 39.8% of the population could request antiviral treatment. As transmission dynamics, severity and timing of the emergence of a novel influenza strain are unknown, the sensitivity analysis produced considerable variation in potential demand (median: 11%, IQR: 2-21%. If the next pandemic strain emerges in late spring or summer and a vaccine is available before the anticipated fall wave, the median prediction was reduced to 6% and IQR to 0.7-14%. Under the strategy of offering empirical treatment to all patients with influenza like symptoms who present for care, demand could increase to between 65 and 144%.The demand for antivirals during a pandemic is uncertain. Unless an accurate, timely and cost-effective test is available to identify influenza cases, demand for antivirals from persons infected with other respiratory viruses will be substantial and have a significant impact on the NAS.

  6. Using stockpile delegation to improve China's strategic oil policy: A multi-dimension stochastic dynamic programming approach

    International Nuclear Information System (INIS)

    There has been much attention paid to oil security in China in recent years. Although China has begun to establish its own strategic petroleum reserve (SPR) to prevent potential losses caused by oil supply interruptions, the system aiming to ensure China's oil security is still incomplete. This paper describes and provides evidence for the benefits of an auxiliary strategic oil policy choice, which aims to strengthen China's oil supply security and offer a solution for strategic oil operations with different holding costs. In this paper, we develop a multi-dimension stochastic dynamic programming model to analyze the oil stockpile delegation policy, which is an intermediate policy between public and private oil stockpiles and is appropriate for the Chinese immature private oil stockpile sector. The model examines the effects of the oil stockpile delegation policy in the context of several distinct situations, including normal world oil market conditions, slight oil supply interruption, and serious oil supply interruption. Operating strategies that respond to different oil supply situations for both the SPR and the delegated oil stockpile were obtained. Different time horizons, interruption times and holding costs of delegated oil stockpiles were examined. The construction process of China's SPR was also taken into account. - Highlights: • We provided an auxiliary strategic oil policy rooted in Chinese local conditions. • The policy strengthen China's capability for preventing oil supply interruption. • We model to obtain the managing strategies for China's strategic petroleum reserve. • Both of the public and delegated oil stockpile were taken into consideration. • The three phase's construction process of China's SPR was taken into account

  9. Algal biochar enhances the re-vegetation of stockpiled mine soils with native grass.

    In most countries the mining industry is required to rehabilitate disturbed land with native vegetation. A typical approach is to stockpile soils during mining and then use this soil to recreate landforms after mining. Soil that has been stockpiled for an extended period typically contains little or no organic matter and nutrient, making soil rehabilitation a slow and difficult process. Here, we take freshwater macroalgae (Oedogonium) cultivated in waste water at a coal-fired power station and use it as a feedstock for the production of biochar, then use this biochar to enhance the rehabilitation of two types of stockpiled soil - a ferrosol and a sodosol - from the adjacent coal mine. While the biomass had relatively high concentrations of some metals, due to its cultivation in waste water, the resulting biochar did not leach metals into the pore water of soil-biochar mixtures. The biochar did, however, contribute essential trace elements (particularly K) to soil pore water. The biochar had very strong positive effects on the establishment and growth of a native plant (Kangaroo grass, Themeda australis) in both of the soils. The addition of the algal biochar to both soils at 10 t ha(-1) reduced the time to germination by the grass and increased the growth and production of plant biomass. Somewhat surprisingly, there was no beneficial effect of a higher application rate (25 t ha(-1)) of the biochar in the ferrosol, which highlights the importance of matching biochar application rates to the requirements of different types of soil. Nevertheless, we demonstrate that algal biochar can be produced from biomass cultivated in waste water and used at low application rates to improve the rehabilitation of a variety of soils typical of coal mines. This novel process links biomass production in waste water to end use of the biomass in land rehabilitation, simultaneously addressing two environmental issues associated with coal-mining and processing.

No other EPCRA Section 313 chemicals were used in 2006 above the reportable thresholds. This document was prepared to provide a description of the evaluation of EPCRA Section 313 chemical use and threshold determinations for LANL for calendar year 2006, as well as to provide background information about data included on the Form R reports. Section 313 of EPCRA specifically requires facilities to submit a Toxic Chemical Release Inventory Report (Form R) to the U.S. Environmental Protection Agency (EPA) and state agencies if the owners and operators manufacture, process, or otherwise use any of the listed toxic chemicals above listed threshold quantities. EPA compiles this data in the Toxic Release Inventory database. Form R reports for each chemical over threshold quantities must be submitted on or before July 1 each year and must cover activities that occurred at the facility during the previous year. In 1999, EPA promulgated a final rule on persistent bioaccumulative toxics (PBTs). This rule added several chemicals to the EPCRA Section 313 list of toxic chemicals and established lower reporting thresholds for these and other PBT chemicals that were already reportable. These lower thresholds became applicable in reporting year 2000. In 2001, EPA expanded the PBT rule to include a lower reporting threshold for lead and lead compounds. Facilities that manufacture, process, or otherwise use more than 100 lb of lead or lead compounds must submit a Form R.

    1998-06-26

    The Federal Emergency Management Information Systems (FEMIS) is an emergency management planning and response tool that was developed by the Pacific Northwest National Laboratory (PNNL) under the direction of the US Army Chemical Biological Defense Command. The FEMIS System Administration Guide provides information necessary for the system administrator to maintain the FEMIS system. The FEMIS system is designed for a single Chemical Stockpile Emergency Preparedness Program (CSEPP) site that has multiple Emergency Operations Centers (EOCs). Each EOC has personal computers (PCs) that emergency planners and operations personnel use to do their jobs. These PCs are connected via a local area network (LAN) to servers that provide EOC-wide services. Each EOC is interconnected to other EOCs via a Wide Area Network (WAN). Thus, FEMIS is an integrated software product that resides on client/server computer architecture. The main body of FEMIS software, referred to as the FEMIS Application Software, resides on the PC client(s) and is directly accessible to emergency management personnel. The remainder of the FEMIS software, referred to as the FEMIS Support Software, resides on the UNIX server. The Support Software provides the communication, data distribution, and notification functionality necessary to operate FEMIS in a networked, client/server environment. The UNIX server provides an Oracle relational database management system (RDBMS) services, ARC/INFO GIS (optional) capabilities, and basic file management services. PNNL developed utilities that reside on the server include the Notification Service, the Command Service that executes the evacuation model, and AutoRecovery. To operate FEMIS, the Application Software must have access to a site specific FEMIS emergency management database. Data that pertains to an individual EOC`s jurisdiction is stored on the EOC`s local server. Information that needs to be accessible to all EOCs is automatically distributed by the FEMIS

  16. A Evaluation of Models of Particulate Suspension for a Thorium Ore Stockpile

    Science.gov (United States)

    Smith, W. John, II

    Fifteen mathematical models of particle saltation, suspension, and resuspension were reviewed and categorized. Appropriate models were applied to the estimation of particulate releases from a hypothetical thorium ore storage pile. An assumed location (near Lemhi Pass, Montana) was used to permit the development of site specific information on ore characteristics and environmental influences. The available models were characterized in terms of suitability for representing aspects of the ore pile, such as rough surface features, wide particle size range, and site specific climate. Five models were selected for detailed study. A computer code for each of these is given. Site specific data for the assumed ore stockpile location were prepared. These data were manipulated to provide the input values required for each of the five models. Representative values and ranges for model variables are tabulated. The response of each model to input data for selected variables was determined. Each model was evaluated in terms of the physical realism of its responses and its overall ability to represent the features of an ore stockpile. The two models providing the best representation were a modified version of the dust suspension subroutine TAILPS from the computer code MILDOS, and the dust suspension formulation from the code REDIST. Their responses are physically reasonable, although different from each other for two parameters: ore moisture and surface roughness. With the input values judged most representative of an ore pile near Lemhi Pass, the estimate of the release of suspended particulates is on the order of 1 g/m('2)-yr.

    The slag stockpiles of coal mines in the Ruhr region primarily have been used as a local recreation area to date. Even the last pope once has visited a dump in Bottrop (Federal Republic of Germany) and has left a permanent impression. Even skiers throw themselves from one of these stockpiles into the depths for some time. Only now the electricity producer RWE AG (Essen, Federal Republic of Germany) and the mining company RAG AG (Herne, Federal Republic of Germany) have used the idea to utilize the difference in height between the summit of the stockpiles and the normal environment energetically. An idea that is now being reviewed extensively by the experts of both companies. If all goes as intended, green power will be generated from the black heritage of Ruhrkohle.

    As the nation's nuclear weapons age and the demands placed on them change, significant challenges face the nuclear stockpile. Risks include material supply issues, ever-increasing lifecycle costs, and loss of technical expertise across the weapons complex. For example, non-nuclear materials are becoming increasingly difficult to replace because manufacturing methods and formulations have evolved in such a way as to render formerly available materials unprofitable, unsafe, or otherwise obsolete. Subtle formulation changes in available materials that occur without the knowledge of the weapons community for proprietary reasons have frequently affected the long-term performance of materials in the nuclear weapon environment. Significant improvements in performance, lifetime, or production cost can be realized with modern synthesis, modeling, and manufacturing methods. For example, there are currently supply and aging issues associated with the insensitive high explosive formulations LX-17 and PBX 9502 that are based on triaminotrinitrobenzene (TATB) and Kel-F, neither of which are commercially available today. Assuring the reliability of the stockpile through surveillance and regularly scheduled Life Extension Programs is an increasingly expensive endeavor. Transforming our current stockpile surveillance--a system based on destructive testing of increasingly valuable assets--to a system based on embedded sensors has a number of potential advantages that include long-term cost savings, reduced risk associated with asset transportation, state-of-health assessments in the field, and active management of the stockpile.

    Many environmental endocrine-disrupting compounds act as ligands for nuclear receptors. Among these receptors, the human pregnane X receptor (hPXR) is well described as a xenobiotic sensor to various classes of chemicals, including pharmaceuticals, pesticides, and steroids. To assess the potential use of PXR as a sensor for aquatic emerging pollutants, we employed an in vitro reporter gene assay (HG5LN-hPXR cells) to screen a panel of environmental chemicals and to assess PXR-active chemicals in (waste) water samples. Of the 57 compounds tested, 37 were active in the bioassay and 10 were identified as new PXR agonists: triazin pesticides (promethryn, terbuthryn, terbutylazine), pharmaceuticals (fenofibrate, bezafibrate, clonazepam, medazepam) and non co-planar polychlorobiphenyls (PCBs; PCB101, 138, 180). Furthermore, we detected potent PXR activity in two types of water samples: passive polar organic compounds integrative sampler (POCIS) extracts from a river moderately impacted by agricultural and urban inputs and three effluents from sewage treatment works (STW). Fractionation of POCIS samples showed the highest PXR activity in the less polar fraction, while in the effluents, PXR activity was mainly associated with the dissolved water phase. Chemical analyses quantified several PXR-active substances (i.e., alkylphenols, hormones, pharmaceuticals, pesticides, PCBs, bisphenol A) in POCIS fractions and effluent extracts. However, mass-balance calculations showed that the analyzed compounds explained only 0.03% and 1.4% of biological activity measured in POCIS and STW samples, respectively. In effluents, bisphenol A and 4-tert-octylphenol were identified as main contributors of instrumentally derived PXR activities. Finally, the PXR bioassay provided complementary information as compared to estrogenic, androgenic, and dioxin-like activity measured in these samples. This study shows the usefulness of HG5LN-hPXR cells to detect PXR-active compounds in water samples

    Uncertainty Quantification (UQ) is a critical field within 21st century simulation science that resides at the very center of the web of emerging predictive capabilities. The science of UQ holds the promise of giving much greater meaning to the results of complex large-scale simulations, allowing for quantifying and bounding uncertainties. This powerful capability will yield new insights into scientific predictions (e.g. Climate) of great impact on both national and international arenas, allow informed decisions on the design of critical experiments (e.g. ICF capsule design, MFE, NE) in many scientific fields, and assign confidence bounds to scientifically predictable outcomes (e.g. nuclear weapons design). In this talk I will discuss a major new strategic initiative (SI) we have developed at Lawrence Livermore National Laboratory to advance the science of Uncertainty Quantification at LLNL focusing in particular on (a) the research and development of new algorithms and methodologies of UQ as applied to multi-physics multi-scale codes, (b) incorporation of these advancements into a global UQ Pipeline (i.e. a computational superstructure) that will simplify user access to sophisticated tools for UQ studies as well as act as a self-guided, self-adapting UQ engine for UQ studies on extreme computing platforms and (c) use laboratory applications as a test bed for new algorithms and methodologies. The initial SI focus has been on applications for the quantification of uncertainty associated with Climate prediction, but the validated UQ methodologies we have developed are now being fed back into Science Based Stockpile Stewardship (SSS) and ICF UQ efforts. To make advancements in several of these UQ grand challenges, I will focus in talk on the following three research areas in our Strategic Initiative: Error Estimation in multi-physics and multi-scale codes ; Tackling the "Curse of High Dimensionality"; and development of an advanced UQ Computational Pipeline to enable

    Full Text Available Accidental or deliberate exposure to chemical, biological, radiological, and nuclear (CBRN agents poses considerable threat throughout the world. Under such conditions, ensuring proper nutrition is a difficult task due to contamination of food available in the affected area. Generally, food is not prepared or served in an environment contaminated by CBRN agents. Foods that are properly packed need to be decontaminated from outside before use. These agents get incorporated in to food chain. Therefore, especially the foliage vegetables, milk and meat products from affected area are not fit for consumption. Potassium iodide has protective role, as radioiodine uptake into the thyroid can be blocked by its pharmacological doses. This is most effective when taken before exposure, but still has significant effects up to five to six hours postexposure. The antioxidant vitamins and minerals may be included in therapeutic feeding programs, as they are known to protect against oxidative stress. Minimum requirement of calories and nutrients are similar to other disasters and are discussed in the present review.

    In this work, a method combining polar organic chemical integrative samplers (POCIS) and ultraperformance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS) was assessed for the determination of two corrosion inhibitors (benzotriazole and methylbenzotriazole), seven pesticides (atrazine, diuron, isoproturon, linuron, metolachlor, penconazole, terbuthylazine), and four pharmaceuticals (carbamazepine, diclofenac, metformin, sulfamethoxazole) in river water. As a first step, two POCIS sorbents, hydrophilic-lipophilic balance (HLB) and Strata X-CW, were compared. The comparison of the uptake profiles of the studied compounds showed that the HLB sorbent provides better uptake (higher sampled amount and better linearity) than Strata X-CW except for the basic compound metformin. Since the sampling rate (R s) of POCIS depends on environmental factors, seven compounds were evaluated as potential performance reference compounds (PRCs) through kinetic experiments. Deisopropylatrazine-d5 (DIA-d5) and, as far as we know, for the first time 4-methylbenzotriazole-d3 showed suitable desorption. The efficiency of both compounds to correct for the effect of water velocity was shown using a channel system in which POCIS were exposed to 2 and 50 cm s(-1). Finally, POCIS were deployed upstream and downstream of agricultural wine-growing and tree-growing areas in the Lienne River and the Uvrier Canal (Switzerland). The impact of the studied areas on both streams could be demonstrated. PMID:26637214

    2010-12-01

    Based on a stochastic, nonlinear, open biochemical reaction system perspective, we present an analytical theory for cellular biochemical processes. The chemical master equation (CME) approach provides a unifying mathematical framework for cellular modeling. We apply this theory to both self-regulating gene networks and phosphorylation-dephosphorylation signaling modules with feedbacks. Two types of bistability are illustrated in mesoscopic biochemical systems: one that has a macroscopic, deterministic counterpart and another that does not. In certain cases, the latter stochastic bistability is shown to be a "ghost" of the extinction phenomenon. We argue the thermal fluctuations inherent in molecular processes do not disappear in mesoscopic cell-sized nonlinear systems; rather they manifest themselves as isogenetic variations on a different time scale. Isogenetic biochemical variations in terms of the stochastic attractors can have extremely long lifetime. Transitions among discrete stochastic attractors spend most of the time in "waiting", exhibit punctuated equilibria. It can be naturally passed to "daughter cells" via a simple growth and division process. The CME system follows a set of nonequilibrium thermodynamic laws that include non-increasing free energy F( t) with external energy drive Q hk ≥0, and total entropy production rate e p =- dF/ dt+ Q hk ≥0. In the thermodynamic limit, with a system's size being infinitely large, the nonlinear bistability in the CME exhibits many of the characteristics of macroscopic equilibrium phase transition.

    Under the Chemical Stockpile Disposal Program (CSDP), the US Army proposes to dispose of lethal chemical agents and munitions stored at eight existing Army installations in the continental United States. In 1988, the US Army issued the final programmatic environmental impact statement (FPEIS) for the CSDP. The FPEIS and the subsequent Record of Decision (ROD) identified an on-site disposal process as the preferred method for destruction of the stockpile. That is, the FPEIS determined the environmentally preferred alternative to be on-site disposal in high-temperature incinerators, while the ROD selected this alternative for implementation as the preferred method for destruction of the stockpile. In this Phase I report, the overall CSDP decision regarding disposal of the PUDA Stockpile is subjected to further analyses, and its validity at PUDA is reviewed with newer, more detailed data than those providing the basis for the conclusions in the FPEIS. The findings of this Phase I report will be factored into the scope of a site-specific environmental impact statement to be prepared for the destruction of the PUDA stockpile. The focus of this Phase I report is on those data identified as having the potential to alter the Army`s previous decision regarding disposal of the PUDA stockpile; however, several other factors beyond the scope of this Phase I report must also be acknowledged to have the potential to change or modify the Army`s decisions regarding PUDA.

    Full Text Available Electrocoagulation is one of methods used to treat wastewater in the coal stockpile without using coagulants. Characteristics of wastewater observed are heavy metals (Fe and Mn and pH.  The decrease in the heavy metals content and the increase in the pH of this wastewater treatment process will then be proposed in the adsorption kinetics model. The influence of  variations in currents and processing time were observed. The time variation of the adsorption process were 60 to 120 minutes with current variations from 1.3 to 3.0 Ampere at a fixed 12 voltages. The results obtained that the Fe content could be decreased to 0.03 ppm at 90 minutes while the content of Mn was decreased to 0.01 ppm at the same time. The increase in pH (7.11 was achieved when applying 2.5 A current at 90 minutes process time. The results obtained from the electrocoagulation method was then proposed in the model of the Langmuir isotherm adsorption kinetics and Freundlich isotherm.

  10. Investigation of the stockpiling and reporting incidents at Ranger and Jabiluka 2002. Supervising Scientist report 170

    International Nuclear Information System (INIS)

    The report has resulted from an investigation by the Supervising Scientist of two incidents that occurred at Ranger and Jabiluka during January and February 2002. These were: 1. the incorrect management of the Grade 2 Stockpile at Ranger; and 2. the failure by the Energy Resources of Australia (ERA) to immediately notify authorities of the exceedence of action levels in Ngarradj (Swift Creek) downstream from Jabiluka. ERA has made a number of commitments to address this failure. Many of these commitments are detailed measures designed to improve ERA's environmental performance and these are supported by the Northern Territory Government, the Northern Land Council and the Supervising Scientist. Of greatest significance has been ERA's commitment, following detailed discussions with the principal stakeholders, to obtaining compliance with, and certification against, the International Standard ISO 14001. Preliminary reports presented by ERA are included in the Appendices. An important conclusion regarding these incidents has been that neither resulted in any harm to the environment of Kakadu National Park or to health of people living in the region

    The following paper aims to test and evaluate the accuracy of UAV data for volumetric measurements to the conventional GNSS techniques. For this purpose, an appropriate open pit quarry has been chosen. Two sets of measurements were performed. Firstly, a stockpile was measured by GNSS technologies and later other terrestrial GNSS measurements for modelling the berms of the quarry were taken. Secondly, the area of the whole quarry including the stockpile site was mapped by a UAV flight. Having considered how dynamic our world is, new techniques and methods should be presented in numerous fields. For instance, the management of an open pit quarry requires gaining, processing and storing a large amount of information which is constantly changing with time. Fast and precise acquisition of measurements regarding the process taking place in a quarry is the key to an effective and stable maintenance. In other words, this means getting an objective evaluations of the processes, using up-to-date technologies and reliable accuracy of the results. Often legislations concerning mine engineering state that the volumetric calculations are to present ±3% accuracy of the whole amount. On one hand, extremely precise measurements could be performed by GNSS technologies, however, it could be really time consuming. On the other hand, UAV photogrammetry presents a fast, accurate method for mapping large areas and calculating stockpiles volumes. The study case was performed as a part of a master thesis.

  13. Verification of Chemical Weapons Destruction

    International Nuclear Information System (INIS)

    The Chemical Weapons Convention is the only multilateral treaty that bans completely an entire category of weapons of mass destruction under international verification arrangements. Possessor States, i.e. those that have chemical weapons stockpiles at the time of becoming party to the CWC, commit to destroying these. All States undertake never to acquire chemical weapons and not to help other States acquire such weapons. The CWC foresees time-bound chemical disarmament. The deadlines for destruction for early entrants to the CWC are provided in the treaty. For late entrants, the Conference of States Parties intervenes to set destruction deadlines. One of the unique features of the CWC is thus the regime for verifying destruction of chemical weapons. But how can you design a system for verification at military sites, while protecting military restricted information? What degree of assurance is considered sufficient in such circumstances? How do you divide the verification costs? How do you deal with production capability and initial declarations of existing stockpiles? The founders of the CWC had to address these and other challenges in designing the treaty. Further refinement of the verification system has followed since the treaty opened for signature in 1993 and since inspection work was initiated following entry-into-force of the treaty in 1997. Most of this work concerns destruction at the two large possessor States, Russia and the United States. Perhaps some of the lessons learned from the OPCW experience may be instructive in a future verification regime for nuclear weapons. (author)

    The operation of a health care facility, such as a cholera or Ebola treatment center in an emergency setting, results in the production of pathogen-laden wastewaters that may potentially lead to onward transmission of the disease. The research presented here evaluated the design and operation of a novel treatment system, successfully used by Médecins Sans Frontières in Haiti to disinfect CTC wastewaters in situ, eliminating the need for road haulage and disposal of the waste to a poorly-managed hazardous waste facility, thereby providing an effective barrier to disease transmission through a novel but simple sanitary intervention. The physico-chemical protocols eventually successfully treated over 600 m3 of wastewater, achieving coagulation/flocculation and disinfection by exposure to high pH (Protocol A) and low pH (Protocol B) environments, using thermotolerant coliforms as a disinfection efficacy index. In Protocol A, the addition of hydrated lime resulted in wastewater disinfection and coagulation/flocculation of suspended solids. In Protocol B, disinfection was achieved by the addition of hydrochloric acid, followed by pH neutralization and coagulation/flocculation of suspended solids using aluminum sulfate. Removal rates achieved were: COD >99%; suspended solids >90%; turbidity >90% and thermotolerant coliforms >99.9%. The proposed approach is the first known successful attempt to disinfect wastewater in a disease outbreak setting without resorting to the alternative, untested, approach of 'super chlorination' which, it has been suggested, may not consistently achieve adequate disinfection. A basic analysis of costs demonstrated a significant saving in reagent costs compared with the less reliable approach of super-chlorination. The proposed approach to in situ sanitation in cholera treatment centers and other disease outbreak settings represents a timely response to a UN call for onsite disinfection of wastewaters generated in such emergencies, and the

    Weather classification approaches may be useful tools in modelling the occurrence of respiratory diseases. The aim of the study is to compare the performance of an objectively defined weather classification and the Spatial Synoptic Classification (SSC) in classifying emergency department (ED) visits for acute asthma depending from weather, air pollutants, and airborne pollen variables for Szeged, Hungary, for the 9-year period 1999-2007. The research is performed for three different pollen-related periods of the year and the annual data set. According to age and gender, nine patient categories, eight meteorological variables, seven chemical air pollutants, and two pollen categories were used. In general, partly dry and cold air and partly warm and humid air aggravate substantially the symptoms of asthmatics. Our major findings are consistent with this establishment. Namely, for the objectively defined weather types favourable conditions for asthma ER visits occur when an anticyclonic ridge weather situation happens with near extreme temperature and humidity parameters. Accordingly, the SSC weather types facilitate aggravating asthmatic conditions if warm or cool weather occur with high humidity in both cases. Favourable conditions for asthma attacks are confirmed in the extreme seasons when atmospheric stability contributes to enrichment of air pollutants. The total efficiency of the two classification approaches is similar in spite of the fact that the methodology for derivation of the individual types within the two classification approaches is completely different.

  18. Cell patterns emerge from coupled chemical and physical fields with cell proliferation dynamics: the Arabidopsis thaliana root as a study system.

    Directory of Open Access Journals (Sweden)

    Rafael A Barrio

    Full Text Available A central issue in developmental biology is to uncover the mechanisms by which stem cells maintain their capacity to regenerate, yet at the same time produce daughter cells that differentiate and attain their ultimate fate as a functional part of a tissue or an organ. In this paper we propose that, during development, cells within growing organs obtain positional information from a macroscopic physical field that is produced in space while cells are proliferating. This dynamical interaction triggers and responds to chemical and genetic processes that are specific to each biological system. We chose the root apical meristem of Arabidopsis thaliana to develop our dynamical model because this system is well studied at the molecular, genetic and cellular levels and has the key traits of multicellular stem-cell niches. We built a dynamical model that couples fundamental molecular mechanisms of the cell cycle to a tension physical field and to auxin dynamics, both of which are known to play a role in root development. We perform extensive numerical calculations that allow for quantitative comparison with experimental measurements that consider the cellular patterns at the root tip. Our model recovers, as an emergent pattern, the transition from proliferative to transition and elongation domains, characteristic of stem-cell niches in multicellular organisms. In addition, we successfully predict altered cellular patterns that are expected under various applied auxin treatments or modified physical growth conditions. Our modeling platform may be extended to explicitly consider gene regulatory networks or to treat other developmental systems.

    The objectives of this study were to determine the composition of stockpiled fescue from December through February over 2 yr and to determine the performance of heifers grazing stockpiled fescue with or without supplemental whole cottonseed. In early December, 36 heifers (initial BW 277 +/- 0.70 kg, yr 1; 266 +/- 2.2 kg, yr 2; and initial BCS of 5.0 +/- 0.04) were assigned randomly to 6 groups. Each group was assigned randomly to a 2.4-ha tall fescue pasture (98% endophyte infected), which had received 76 kg of N/ha on September 1. Group was the experimental unit for all measures. Forage DM available during grazing (to ground level) averaged 3,913 and 5,370 kg/ha in yr 1 and 2, respectively. The pasture was strip-grazed for 83 d, with daily forage allocation. Three groups were fed whole cottonseed (0.90 kg of DM/heifer; 24.4% CP, DM basis) daily at 0.33% of BW, and a small amount of a corn-based concentrate (0.19 kg of DM/heifer) to assure complete cottonseed consumption. Nutritive value of forage (dry basis) was determined each week by sampling each pasture to the 5-cm target grazing height. Forage disappearance was estimated every 2 wk from pre- and postgraze forage mass. Forage CP was 16.8% in yr 1 and 12.6% in yr 2. In vitro true organic matter digestibility (IVTOMD) was 82.0 and 71.9%, and ADF was 25.9 and 30.7% in yr 1 and 2, respectively. Most indicators of forage quality declined slightly through the winter, although they recovered in late winter in yr 1. The proportion of fescue that was green declined (P < 0.05) from December (79% in yr 1 and 64% in yr 2) to February (62% in yr 1 and 52% in yr 2). Green tissue averaged 20.4 and 15.2% CP, 91 and 87% IVTOMD, and 22.1 and 23.3% ADF in yr 1 and 2, respectively. Brown tissue averaged 10.3 and 8.5% CP, 64 and 62% IVTOMD, and 35.7 and 37.4% ADF in yr 1 and 2, respectively.

    Full Text Available Aysegul Nalca, Elizabeth E ZumbrunCenter for Aerobiological Sciences, US Army Medical Research Institute of Infectious Diseases (USAMRIID, Fort Detrick, MD, USAAbstract: Smallpox was eradicated more than 30 years ago, but heightened concerns over bioterrorism have brought smallpox and smallpox vaccination back to the forefront. The previously licensed smallpox vaccine in the United States, Dryvax® (Wyeth Laboratories, Inc., was highly effective, but the supply was insufficient to vaccinate the entire current US population. Additionally, Dryvax® had a questionable safety profile since it consisted of a pool of vaccinia virus strains with varying degrees of virulence, and was grown on the skin of calves, an outdated technique that poses an unnecessary risk of contamination. The US government has therefore recently supported development of an improved live vaccinia virus smallpox vaccine. This initiative has resulted in the development of ACAM2000™ (Acambis, Inc.™, a single plaque-purified vaccinia virus derivative of Dryvax®, aseptically propagated in cell culture. Preclinical and clinical trials reported in 2008 demonstrated that ACAM2000™ has comparable immunogenicity to that of Dryvax®, and causes a similar frequency of adverse events. Furthermore, like Dryvax®, ACAM2000™ vaccination has been shown by careful cardiac screening to result in an unexpectedly high rate of myocarditis and pericarditis. ACAM2000™ received US Food and Drug Administration (FDA approval in August 2007, and replaced Dryvax® for all smallpox vaccinations in February 2008. Currently, over 200 million doses of ACAM2000™ have been produced for the US Strategic National Stockpile. This review of ACAM2000™ addresses the production, characterization, clinical trials, and adverse events associated with this new smallpox vaccine.Keywords: smallpox, vaccinia, variola, vaccine, efficacy, safety

  3. Nuclear emergencies and protective actions

    International Nuclear Information System (INIS)

    Although technical improvements have increased the safety of new and old nuclear power plants, many simultaneous component failures and/or human errors are improbable but possible. Both the plant (on-site) and the nearby area (off-site) have emergency plans. Rescue service authorities are responsible of the off-site. The main protective actions are sheltering, evacuation and iodine ingestion. The Loviisa off-site emergency plan assumes that a major part of this population takes care of their own protective actions; Rescue service authorities can then concentrate on the coordination activities and to those people who need help. To be able to carry out the protective actions timely and effectively the people should have information on radiation risk and emergency planning. In case of a potential accident the local population should follow the rescue service information and know how to shelter and how to evacuate themselves. Though there are many stockpiles of iodine pellets in the area the rescue service authorities recommend that each household should purchase iodine pellets for their own need. The utility and the rescue service authorities have distributed information brochures to all homes within 30 km from Loviisa NPP since 1990. This brochure gives information on radiation and protective actions in case of an accident. Because the brochures might not stay available and so also the local telephone book contains this information

    2016-03-01

    Concentrations, spatial distribution, and sources of 16 polycyclic aromatic hydrocarbons (PAHs), listed as priority pollutants by the United States Environmental Protection Agency (USEPA), were investigated in surface soils of three different coal stockpile, agricultural, and residential sites in South Kalimantan Province, Indonesia. Total PAHs concentration ranged from 4.69 to 22.67 mg kg(-1)-dw. PAHs concentrations in soil of coal stockpile sites were higher than those in agricultural and residential soil. A complex of petrogenic origin and pyrolytic sources was found within the study area, as suggested by the isomeric ratios of PAHs. The results of principal component analysis and multiple linear regressions (PCA/MLR) showed that three sources contributed to the PAHs in the study area, including biomass and coal combustion (48.46 %), raw coal (35.49 %), and vehicular emission (16.05 %). The high value of total benzo[a]pyrene equivalent concentration (B[a]Peq) suggests that local residents are exposed to a high carcinogenic potential. PMID:26861742

  6. A study on possible use of Urtica dioica (common nettle) plants as uranium (234U, 238U) contamination bioindicator near phosphogypsum stockpile

    International Nuclear Information System (INIS)

    The aim of this study was to determine uranium concentrations in common nettle (Urtica dioica) plants and corresponding soils samples which were collected from the area of phosphogypsum stockpile in Wislinka (northern Poland). The uranium concentrations in roots depended on its concentrations in soils. Calculated BCF and TF values showed that soils characteristics and air deposition affect uranium absorption and that different uranium species have different affinities to U. dioica plants. The values of 234U/238U activity ratio indicate natural origin of these radioisotopes in analyzed plants. Uranium concentration in plants roots is negatively weakly correlated with distance from phosphogypsum stockpile. (author)

    Stockpiled tall fescue can provide adequate winter forage for beef cattle, although unsupplemented replacement heifers may display marginal performance before breeding. The objective of this study was to determine if protein supplementation and/or additional forage improves growth and reproductive performance of replacement heifers grazing stockpiled fescue. Cattle averaging 272 ± 1.59 kg were stratified by BW and then randomly assigned to 1 of 4 plots within a pasture replication. Treatment combinations were assigned in a 2 × 2 factorial arrangement and included 1) a conservative forage allocation ("normal," targeting 85% forage use) and mineral supplement (normal forage allocation with mineral supplement [FM]), 2) normal forage allocation with protein tub (FT), 3) more liberal forage allocation ("extra," targeting 70% forage use) and mineral supplement (extra forage allocation with mineral supplement [EM]), and 4) "extra forage allocation with protein tub (ET). Treatments were administered for 8 wk from early November to early January. Heifers were fed fescue hay for 1 wk before breeding in late January. Heifers were synchronized with the 7-d CO-Synch + controlled internal drug release device protocol and inseminated in late January. Heifers were checked for pregnancy by ultrasonography at 35 and 90 d after AI. Main and interaction effects between the 2 treatments were determined. Total supplement intake was greater for protein tub than mineral supplement (0.36 vs. 0.11 kg·heifer·d, respectively; heifer·d for FM, FT, EM, and ET, respectively). There was an interaction effect of the 2 treatments on change in BCS ( 0.05). Overall, feeding a protein supplement or providing extra forage increased gain and interacted to increase BCS but did not have an effect on reproductive performance. Supplementing with protein and providing extra forage are strategies that can increase gain in heifers, which could aid heifers in reaching puberty before estrous synchronization

    Sandia National Laboratories has conducted proof-of-concept experiments demonstrating effective knockdown and neutralization of aerosolized CBW simulants using charged DF-200 decontaminant sprays. DF-200 is an aqueous decontaminant, developed by Sandia National Laboratories, and procured and fielded by the US Military. Of significance is the potential application of this fundamental technology to numerous applications including mitigation and neutralization of releases arising during chemical demilitarization operations. A release mitigation spray safety system will remove airborne contaminants from an accidental release during operations, to protect personnel and limit contamination. Sandia National Laboratories recently (November, 2008) secured funding from the US Army's Program Manager for Non-Stockpile Chemical Materials Agency (PMNSCMA) to investigate use of mitigation spray systems for chemical demilitarization applications. For non-stockpile processes, mitigation spray systems co-located with the current Explosive Destruction System (EDS) will provide security both as an operational protective measure and in the event of an accidental release. Additionally, 'tented' mitigation spray systems for native or foreign remediation and recovery operations will contain accidental releases arising from removal of underground, unstable CBW munitions. A mitigation spray system for highly controlled stockpile operations will provide defense from accidental spills or leaks during routine procedures.

    Full Text Available The Chemical Weapons Convention (CWC is briefly characterised by stressing its main pillars, such as verified destruction ofCWstockpiles and destruction/conversion ofCWproduction facilities (CWPFs, verified non-production of CW by the chemical industries, assistance and protection, and international cooperation. The CWC´s leading principle in defining theCW(protecting it generally against scientific and technological development, i. e. so called General Purpose Criterion is thoroughly elucidated showing its relation to the CWC´s sophisticated verification system. Status of implementation (as of August 2005 shows main data obligatory declared by the States Parties (SP, among them 6 possessors of CW stockpiles (Russia, USA, India, South Korea, Albania and Libya. From the declared 71 373 agent-tons, 12 889 have been destroyed, from the declared 8 679 M items of munitions (containers, 2 420 have been destroyed, which means that the anticipated 10 years deadline for CW destruction (after entry into force – EIF will be not managed. For Russia and USA the allowed extension by another 5 years has been already agreed. From the 64 CWPFs (operational after 1946, declared by 12 SPs, 53 have been certified as destroyed/converted. The Organisation for the Prohibition of Chemical Weapons (OPCW is briefly presented and main results of the First Review Conference (2003 analysed on the base of the adopted principal documents. Future problems of implementing the CWC are connected in the first line with its universality, because among 16 non-SPs, several countries (located mainly in the Near East and on the Korean peninsula are presumed to be CW-possessors. Special emphasis is laid on both, threats and benefits of the scientific and technological development for current implementing the CWC as well as of its implementation in future after all CW stockpiles have been destroyed.

    2016-02-01

    Significant strides have been made over the past 10 to 15 years to develop medical countermeasures (MCMs) to address potential disaster hazards, including chemical, biological, radiologic, and nuclear threats. Significant and effective collaboration between the pediatric health community, including the American Academy of Pediatrics, and federal partners, such as the Office of the Assistant Secretary for Preparedness and Response, Centers for Disease Control and Prevention, Federal Emergency Management Agency, National Institutes of Health, Food and Drug Administration, and other federal agencies, over the past 5 years has resulted in substantial gains in addressing the needs of children related to disaster preparedness in general and MCMs in particular. Yet, major gaps still remain related to MCMs for children, a population highly vulnerable to the effects of exposure to such threats, because many vaccines and pharmaceuticals approved for use by adults as MCMs do not yet have pediatric formulations, dosing information, or safety information. As a result, the nation's stockpiles and other caches (designated supply of MCMs) where pharmacotherapeutic and other MCMs are stored are less prepared to address the needs of children compared with those of adults in the event of a disaster. This policy statement provides recommendations to close the remaining gaps for the development and use of MCMs in children during public health emergencies or disasters. The progress made by federal agencies to date to address the needs of children and the shared commitment of collaboration that characterizes the current relationship between the pediatric health community and the federal agencies responsible for MCMs should encourage all child advocates to invest the necessary energy and resources now to complete the process of remedying the remaining significant gaps in preparedness.

    The applicability of thermal photography in determination of basic drying level of a peat production field. Additionally, the utilization of aerial photographs for determination of peat the volumes of peat stockpiles. Suitability of thermal photography for determination of basic drying level of a peat production field was studied by photographing the production field both from an aeroplane and from the ground. Thermal photographing of peat layer was also made in laboratory. Moisture measuring samples were taken from the surface of the peat layer from the depth of 1-2 cm simultaneously with the photographing. On the basis of the research results it has been possible to show the remarkable correlation between the moisture content of the peat surface and the surface temperature when the moisture differences were high (> 20 %). In the case of small moisture differences (< 10 %) no clear correlation was noticed between the moisture content of the peat surface and the surface temperature. The suitability of aerial photography for determination of the volumes of peat stockpiles was studied by photographing 5 stockpiles by recording camera from an aeroplane and by determination of the volumes both photogrammetrically and in the field. According to the results the accuracy of volume determination using volume determination from aerial photographs will probably be sufficient for practical purposes. According to the experiences of the autumns 1991 and 1992 it, however, seems that the operational accuracy of recording camera photography in autumn is not, due to the weather, sufficient to ensure the results in agreed time in large-scale stockpile photography

    In greenhouse experiment, the seed samples of 3 populations were treated with treatments including: cold stratification, Gibberlic Acid (50 ppm and 100 ppm), Potassium nitrate (0.2%, 0.4%), physical scarification (sand paper), chemical scarification (Ethylic alcohol 70%) and distilled water (control), then these treated seed samples were sown in pots as randomize design with three replication. The germination characteristics including: germination percentage, speed of germination, length of root and shoot, seedling length, ratio of root length by shoot length, vigor index, fresh weight arid dry weight, ratio of dry weight by fresh weight were evaluated during 45 days of experiment. Comparing between three populations of Sahandy savory, seed germination characteristics of the Ghazvin population was higher than the other two populations. According to effect of treatment on germination seed characteristics, the species of savory and their population, it was concluded that effect of Gibberlic Acid and Potassium nitrate was higher than physical scarification and chemical scarification comparing with control. With more effective of gibberlic acid and KNO3 and cold treatment on seed germination enhancement of the population, it was clarified that the type of dormancy of some population of Sahandy savory was physiological dormancy.

  4. Factors that elevate the internal radionuclide and chemical retention, dose and health risks to infants and children in a radiological-nuclear emergency

    International Nuclear Information System (INIS)

    The factors that influence the dose and risk to vulnerable population groups from exposure and internal uptake of chemicals are examined and, in particular, the radionuclides released in chemical, biological, radiological, nuclear and explosive events. The paper seeks to identify the areas that would benefit from further research. The intake and body burdens of carbon and calcium were assessed as surrogates for contaminants that either act like or bind to hydrocarbons (e.g. tritium and 14C) or bone-seeking radionuclides (e.g. 90Sr and 239Pu). The shortest turnover times for such materials in the whole body were evaluated for the newborn: 11 d and 0.5 y for carbon and calcium, respectively. However, their biokinetic behaviour is complicated by a particularly high percentage of the gut-absorbed dietary intake of carbon (∼16%) and calcium (∼100%) that is incorporated into the soft tissue and skeleton of the growing neonate. The International Commission on Radiological Protection dose coefficients (Sv Bq-1) were examined for 14 radionuclides, including 9 of concern because of their potential use in radiological dispersal devices. The dose coefficients for a 3-month-old are greater than those for adults (2-56 times more for ingestion and 2-12 times for inhalation). The age-dependent dose and exposure assessment of contaminant intakes would improve by accounting for gender and growth where it is currently neglected. Health risk is evaluated as the product of the exposure and hazard factors, the latter being about 10-fold greater in infants than in adults. The exposure factor is also approximately 10-fold higher for ingestion by infants than by adults, and unity for inhalation varying with the contaminant. Qualitative and quantitative physiological and epidemiological evidence supports infants being more vulnerable to cancer and neurological deficit than older children). (authors)

  6. The Army and chemical weapons destruction: Implementation in a changing context

    International Nuclear Information System (INIS)

    In 1985, Congress directed the Army to destroy the nation's stockpile of chemical weapons. The estimate was that this task could be accomplished by 1994 at a cost of $1.7 billion. By 1998, only a portion of the stockpile has been destroyed, the deadline extended to 2007 and the estimated cost had risen to approximately $16 billion. This paper discusses the factors underlying cost escalation and missed deadlines. It examines the diffusion of control over the implementation process surrounding the chemical weapons demilitarization (Chem Demil) program in the US. Focusing on the role of the Army and its difficulties in adjusting strategies in the face of political change from the Cold War to the post-Cold War setting, it analyzes the course of implementation through three converging streams of political activity. What differentiates the federal, intergovernmental, and international streams are the nature and number of actors, and the type of pressures with which the Army must deal

    The Pine Bluff Arsenal (PBA) near Pine Bluff, Arkansas, is one of eight continental United States (CONUS) Army installations where lethal unitary chemical agents and munitions are stored and where destruction of agents and munitions is proposed under the Chemical Stockpile Disposal Program (CSDP). The chemical agent inventory at PBA consists of approximately 12%, by weight, of the total US stockpile. The destruction of the stockpile is necessary to eliminate the risk to the public from continued storage and to dispose of obsolete and leaking munitions. In 1988 the US Army issued a Final Programmatic Environmental Impact Statement (FPEIS) for the CSDP that identified on-site disposal of agents and munitions as the environmentally preferred alternative (i.e., the alternative with the least potential to cause significant adverse impacts). The purpose of this report is to examine the proposed implementation of on-site disposal at PBA in light of more recent and more detailed data than those on which the FPEIS is based. New population data were used to compute fatalities using the same computation methods and values for all other parameters as in the FPEIS. Results indicate that all alternatives are indistinguishable when the potential health impacts to the PBA community are considered. However, risks from on-site disposal are in all cases equal to or less than risks from other alternatives. Furthermore, no unique resources with the potential to prevent or delay implementation of on-site disposal at PBA have been identified.

    2007-06-01

    A winter grazing experiment was conducted to evaluate the effects of stocking rate and corn gluten feed supplementation on forage mass and composition and the BW and BCS of bred 2-yr-old cows grazing stockpiled forage during winter. Two 12.2-ha blocks containing Fawn, endophyte-free, tall fescue and red clover were each divided into 4 pastures of 2.53 or 3.54 ha. Hay was harvested from the pastures in June and August of 2003 and 2004, and N was applied at 50.5 kg/ha at the initiation of stockpiling in August. On October 22, 2003, and October 20, 2004, twenty-four 30-mo-old Angus-Simmental and Angus cows were allotted by BW and BCS to strip-graze for 147 d at 0.84 or 1.19 cow/ha. Eight similar cows were allotted to 2 dry lots and fed tall fescue-red clover hay ad libitum. Corn gluten feed was fed to cows in 2 pastures to maintain a mean BCS of 5 (9-point scale) at each stocking rate and in the dry lots (high supplementation level) or when weather prevented grazing (low supplementation level) in the remaining 2 pastures at each stocking rate. Mean concentrations of CP in yr 1 and 2 and IVDMD in yr 2 were greater (P corn gluten feed supplemented to cows in yr 1 and 2 were 46 and 60 kg/ cow and did not differ (P = 0.33, yr 1; P = 0.50, yr 2) between cows fed hay or grazing stockpiled forage in either year. Estimated production costs were greater for cows in the dry lots because of hay feeding. PMID:17296771

  20. Emerging images

    KAUST Repository

    Mitra, Niloy J.

    2009-01-01

    Emergence refers to the unique human ability to aggregate information from seemingly meaningless pieces, and to perceive a whole that is meaningful. This special skill of humans can constitute an effective scheme to tell humans and machines apart. This paper presents a synthesis technique to generate images of 3D objects that are detectable by humans, but difficult for an automatic algorithm to recognize. The technique allows generating an infinite number of images with emerging figures. Our algorithm is designed so that locally the synthesized images divulge little useful information or cues to assist any segmentation or recognition procedure. Therefore, as we demonstrate, computer vision algorithms are incapable of effectively processing such images. However, when a human observer is presented with an emergence image, synthesized using an object she is familiar with, the figure emerges when observed as a whole. We can control the difficulty level of perceiving the emergence effect through a limited set of parameters. A procedure that synthesizes emergence images can be an effective tool for exploring and understanding the factors affecting computer vision techniques. © 2009 ACM.

  3. The cause and effect of exclusionary zoning within a jurisdiction, and, The stockpile of petroleum needed to contain OPEC's price shocks

    Science.gov (United States)

    Vatter, Marc H.

    In Part I, I model a jurisdiction where residents differ by income, and housing confers benefits on neighbors. By majority vote, residents choose minima on consumption of housing that differ by neighborhood, and they separate into neighborhoods by income. In practice, such laws take the form of minimum lot sizes, bans on multi-family units, building codes, and other restrictions. This policy maximizes a benefit-cost welfare criterion. Alternative policies include no minima and a uniform minimum citywide, based on libertarian and utilitarian welfare criteria, respectively. I compare the policies in terms of efficiency, implementability, and distributional consequences, and give numerical examples based on U.S. data. Willingness to pay for the benefit-cost optimum is convex in income. This helps to explain why neighborhood stratification by income has outpaced stratification of income itself in U.S metropolitan areas since 1970. In the examples, gains to a rich household are in the thousands and losses to the poor in the hundreds of dollars annually. In Part II, I estimate the stockpile of petroleum sufficient to contain a price shock perpetrated by the OPEC. I estimate world demand for petroleum such that the long run price elasticity exceeds that in the short run, and supply from non-OPEC producers with a similar kind of lagged response. Given this structure for elasticities, OPEC profits from sudden increases in price. I simulate interaction among consumers, non-OPEC producers, OPEC, and an International Energy Agency (IEA) that punishes OPEC by releasing oil onto the market. I endow the IEA with increasingly large stockpiles until they suffice to limit price shocks to specified levels. Every 5 reduction in the shock raises present-valued world GDP by about 650 billion. The IEA now has 1.4 billion barrels of petroleum, including 700 million in the U.S. Strategic Petroleum Reserve. A 3 billion barrel stockpile would suffice to reduce a 35 price shock to 20, raising

  5. Oil and Gas Emergency Policy: Japan 2013 update

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2013-06-01

    Oil remains the most significant energy source in Japan, accounting for some 45% of the country’s total primary energy supply (TPES) in 2011. Japan’s oil demand steadily decreased from 5.71 mb/d in 1997 to 4.47 mb/d in 2010. However, its oil demand increased to 4.48 mb/d in 2011 and 4.73 mb/d in 2012 due to the Great East Japan Earthquake in March 2011 and its subsequent impacts. The transport sector represented around 38% of total consumption in 2010, while the industry sector accounted for 30%. A significant proportion of the industry sector’s oil demand comes from the chemical industry. Of the 4.8 mb/d of oil imported by Japan in 2012, 3.5 mb/d consisted of crude oil, 209 kb/d of NGLs and feedstocks, and some 1.2 mb/d of refined products. About 83% of Japan’s crude oil imports in 2012 came from the Middle East. The country has 27 operational refineries with a total crude distillation capacity of around 4.5 mb/d. Japan meets its 90-day stockholding obligation to the IEA by holding government emergency stocks and by placing a minimum stockholding obligation on industry. JOGMEC’s primary role is to manage public stocks under the Oil Stockpiling Act, while industry (refineries, specified distributors and importers) is obliged to hold the equivalent of 70 days of their daily imports, sales or refinery production, based on the average of the previous 12 months. The public stocks mostly consist of crude oil, but the Administration has expanded its emergency inventory to include four categories of refined products - gasoline, kerosene, fuel oil and diesel oil. Japan held some 591 million barrels (mb) of oil stocks at the end of January 2013, equating to 166 days of 2011 net-imports (92 days of government stocks and 74 days of industry stocks). Around 72% of total stocks were held in the form of crude oil. Japan has consistently met its minimum IEA stockholding obligation. The share of natural gas in the country’s TPES increased significantly from 17% in 2010

    Full Text Available In recent years, the surprising progress made in other areas of hematology (advances in the understanding of leukemogenesis, improved transplant techniques has been conspicuously absent in the management of hematologic emergencies. And yet, every step toward greater knowledge, every new treatment option will be of little value unless we are able to manage the acute complications of hematologic diseases. These complications are better defined as hematologic emergencies, and they are characterized by a high rate of mortality. This review is based on a search of the literature that was initially confined to articles published in the journal Hematology from 2000 to 2009. The search was then extended to the Cochrane Library and to Pub Med in February 2010 with the following Keywords emergencies; urgencies; hematology. The same key words were employed in a search of the archives of Blood and the New England Journal of Medicine from 2000 to 2010. The results confirm that hematologic emergencies can be caused by hematologic malignancies as well as by non-neoplastic hematologic diseases. Within the former category; this review examines the causes; manifestations; treatment and prevention of disseminated intravascular coagulation; superior vena caval syndrome; spinal cord compression; tumor lysis syndrome; hyperleukocytosis; and hypercalcemia. We also review emergency situations associated with non-neoplatic haematological diseases; such as thrombotic thrombocytopenic purpura; drug-induced hemolytic anemia; and acute sickle-cell crisis.

The risk of grave accident is so limited to a very low level of probability. He cannot be however completely pushed aside. The expression ' radiological emergency situation ' indicates a situation which ensues from an incident or of an accident risking to lead to an emission of radioactive materials or a level of radioactivity susceptible to strike a blow at the public health. The term ' nuclear crisis ' is used for the events which can lead to a radiological emergency situation on a nuclear basic installation or during a transport of radioactive materials. The preparation and the management of emergency situations, that they are of natural, accidental or terrorist origin, became a major concern of our society.

    Full Text Available There have been numerous attempts to control fertility after unprotected sexual intercourse. From very bizarre methods like the vaginal application of Coca Cola to the more serious attempts using calcium antagonists influencing fertility parameters in sperm to hormonal methods or intrauterine devices. So far, hormonal methods preventing or delaying ovulation have proved to be the most popular starting with the combination of ethinyl estradiol and levonorgestrel, known as the Yuzpe regimen. The first dose had to be taken within 72 hours of unprotected intercourse, a second one 12 hours later. Later on, levonorgestrel alone, at first in a regimen similar to the Yuzpe method (2 × 0.75 mg 12 hours apart showed to be more successful, eventually resulting in the development of a 1.5 mg levonorgestrel pill that combined good efficacy with a high ease of use. It has become the standard method used up to this day in most countries. Since the mid 1970s copper IUDs have been used for emergency contraception, which show a high efficacy. Their disadvantages lie in the fact that emergency contraception is considered an off label use and that they might not be acceptable for every patient. Mifepristone in doses of 10 or 25 mg is being used successfully as an emergency contraceptive in China, but has never received any significant consideration in Western countries. The most recent development is the approval of the selective progesterone receptor modulator ulipristal acetate in the dosage of 30 mg for emergency contraception up to 5 days after unprotected intercourse, combining the safe and easy application of the single dose levonorgestrel pill with an even higher efficacy. Several efficacious and easy to use methods for emergency contraception are available on the market today with the most widely spread being levonorgestrel in a single dose of 1.5 mg (given as one tablet of 1.5 mg or 2 tablets of 0.75 mg each for administration up to 3 days after

  3. Emerging issues

    International Nuclear Information System (INIS)

    Some formal and informal mechanisms were implemented at the Ontario Ministry of the Environment that allow the identification of emerging environmental issues. The early warning is most often provided through the expertise of the personnel and their contacts. The Ministry commissioned a study to review the process, learn from the processes in place in other organizations, and implement the appropriate changes into its emerging issues procedure. The team conducting the review answered four specific questions. The first question was: What are the necessary elements of an emerging issues tool? The second question was: What are some of the best practices in other jurisdictions? It was followed by the question: How do those jurisdictions implement emerging issues models? The final question was: What implementation is appropriate for the Ontario Ministry of the Environment? The approach involved reviewing the appropriate literature and reviewing the best practices in place in other jurisdictions, both in the United States and in Europe. Senior officials in Canada and the United States were interviewed, and the procedure was identified and described. A case study concerning the acid rain problem in the 1960s and 1970s was used to test the developed procedure retroactively. This procedure involves a variation of the top-down, bottom-up input procedure at the United States Environmental Protection Agency (US EPA), with a formal issues scanning process, and the prioritizing and analysis of the steps. It was noted that if the procedure had been in place in the late 1960s in Ontario, it would have been possible to identify one or more impacts from the acid rain situation ten years earlier. Preventive and remedial action could have been implemented, leading to environmental and economic benefits for the province of Ontario. The broad involvement of stakeholders is required for an open and systematic prioritization of the issues. The authors concluded the study by identifying

    Chemical and biochemical sensors have experienced tremendous growth in the past decade due to advances in material chemistry combined with the emergence of digital communication technologies and wireless sensor networks (WSNs) [1]. The emergence of wearable chemical and biochemical sensors is a relatively new concept that poses unique challenges to the field of wearable sensing. This is because chemical sensors have a more complex mode of operation, compared to physical transducers, in that t...

  5. Emerging Jets

    2015-01-01

    In this work, we propose a novel search strategy for new physics at the LHC that utilizes calorimeter jets that (i) are composed dominantly of displaced tracks and (ii) have many different vertices within the jet cone. Such emerging jet signatures are smoking guns for models with a composite dark sector where a parton shower in the dark sector is followed by displaced decays of dark pions back to SM jets. No current LHC searches are sensitive to this type of phenomenology. We perform a detailed simulation for a benchmark signal with two regular and two emerging jets, and present and implement strategies to suppress QCD backgrounds by up to six orders of magnitude. At the 14 TeV LHC, this signature can be probed with mediator masses as large as 1.5 TeV for a range of dark pion lifetimes, and the reach is increased further at the high-luminosity LHC. The emerging jet search is also sensitive to a broad class of long-lived phenomena, and we show this for a supersymmetric model with R-parity violation. Possibilit...

  7. Hypertensive emergencies.

    1995-11-01

    Hypertensive emergencies are uncommon and physiologically diverse. Consequently, it is difficult for most physicians to develop a familiarity with all the different hypertensive crises and with all drugs available for treating them (Table 4). Clinicians should not agonize over which is the perfect therapeutic agent for a particular emergency, but instead, they should focus on scrupulous monitoring and familiarize themselves with a few agents that will serve in most situations. Generally, these agents will be sodium nitroprusside and nitroglycerin. Vigilant neurologic monitoring is mandatory in all hypertensive emergencies. The early symptoms and signs of cerebral hypoperfusion can be vague and subtle, but if recognized, serious complications of therapy can be avoided. Remember, the patient may still be hypertensive. Avoid acute (during the first hour) reductions in MAP of more than 20% whenever possible; subsequent reductions should be gradual. In patients known to have markedly elevated ICP and who need acute reductions in their BP, serious consideration should be given to direct monitoring of the ICP so that CPP can be maintained within safe limits. In general, oral agents should not be used for the treatment of hypertensive emergencies. Intravenous Labetalol and intravenous nicardipine are not suitable for general use in hypertensive emergencies. In special situations (e.g., perioperative hypertension and subarachnoid hemorrhage), however, they may be employed. Their role may expand with further study. Trimethaphan may be superior to nitroprusside for hypertension complicated by elevated ICP or cerebral dysfunction. Realistically, most physicians will continue to use nitroprusside. Intense neurologic monitoring is more important than the specific agent used. Nitroglycerin is the agent of choice for acute ischemic heart disease complicated by severe hypertension; if it fails, use nitroprusside. For aortic dissection, the combination of nitroprusside and IV

    The Pine Bluff Arsenal (PBA) near Pine Bluff, Arkansas, is one of eight continental United States (CONUS) Army installations where lethal unitary chemical agents and munitions are stored and where destruction of agents and munitions is proposed under the Chemical Stockpile Disposal Program (CSDP). The chemical agent inventory at PBA consists of approximately 12%, by weight, of the total US stockpile. The destruction of the stockpile is necessary to eliminate the risk to the public from continued storage and to dispose of obsolete and leaking munitions. In 1988 the US Army issued a Final Programmatic Environmental Impact Statement (FPEIS) for the CSDP that identified on-site disposal of agents and munitions as the environmentally preferred alternative (i.e., the alternative with the least potential to cause significant adverse impacts). The purpose of this report is to examine the proposed implementation of on-site disposal at PBA in light of more recent and more detailed data than those on which the FPEIS is based. New population data were used to compute fatalities using the same computation methods and values for all other parameters as in the FPEIS. Results indicate that all alternatives are indistinguishable when the potential health impacts to the PBA community are considered. However, risks from on-site disposal are in all cases equal to or less than risks from other alternatives. Furthermore, no unique resources with the potential to prevent or delay implementation of on-site disposal at PBA have been identified.

    Many mechanisms, functions and structures of life have been unraveled. However, the fundamental driving force that propelled chemical evolution and led to life has remained obscure. The second law of thermodynamics, written as an equation of motion, reveals that elemental abiotic matter evolves from the equilibrium via chemical reactions that couple to external energy towards complex biotic non-equilibrium systems. Each time a new mechanism of energy transduction emerges, e.g., by random variation in syntheses, evolution prompts by punctuation and settles to a stasis when the accessed free energy has been consumed. The evolutionary course towards an increasingly larger energy transduction system accumulates a diversity of energy transduction mechanisms, i.e. species. The rate of entropy increase is identified as the fitness criterion among the diverse mechanisms, which places the theory of evolution by natural selection on the fundamental thermodynamic principle with no demarcation line between inanimate and animate.

    The environmental impact of using wood chips instead of straw bedding with feedlot manure on transport and leaching potential from feedlot manure is unknown. Our main objective was to determine if transport of total N, total organic N, NO-N, and nonpurgeable organic C (NPOC) to subsurface soil was lower for soils amended with feedlot manure if combined with wood chips compared with straw. A secondary objective was to compare transport of N and NPOC with organic amendments versus inorganic fertilizer. Stockpiled feedlot manure (SM) with wood chip (SM-WD) or barley straw (SM-ST) bedding at 39 Mg (dry wt.) ha, and inorganic fertilizer (IN) at 100 kg N ha, was applied annually for 13 yr to a clay loam soil in a replicated field experiment in southern Alberta, Canada. Intact soil cores were taken in fall 2011 (0-30 cm depth) from the three treatments, and the residual N and NPOC were eluted from the soil cores. Total N, total organic N, and NPOC were determined on filtered (1.0 μm) effluent samples that are primarily dissolved fraction but may contain some small particulate N and C. Peak concentrations, flow-weighted mean concentrations, and mass loss of total N, total organic N, NO-N, and NPOC were significantly ( ≤ 0.05) lower by 35 to 86% for SM-WD compared with SM-ST. Mean recoveries were also significantly lower for SM-WD than SM-ST by 0.07 to 8% (absolute difference). The transport behavior was similar for SM-WD and IN treatment, but solute transport was greater for SM-ST than for IN. Application of stockpiled feedlot manure with wood chips instead of straw bedding may be a beneficial management practice to reduce transport and leaching potential of N fractions and NPOC.

    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.

    Emergency contraception (EC) may help prevent pregnancy in various circumstances, such as contraceptive method failure, unprotected sexual intercourse, or sexual assault, yet it remains underused. There are 4 approved EC options in the United States. Although ulipristal acetate requires a provider's prescription, oral levonorgestrel (LNG) is available over the counter for women of all ages. The most effective method of EC is the copper intrauterine device, which can be left in place for up to 10 years for efficacious, cost-effective, hormone-free, and convenient long-term primary contraception. Ulipristal acetate tends to be more efficacious in pregnancy prevention than is LNG, especially when taken later than 72 hours postcoitus. The mechanism of action of oral EC is delay of ovulation, and current evidence reveals that it is ineffective postovulation. Women who weigh more than 75 kg or have a body mass index greater than 25 kg/m(2) may have a higher risk of unintended pregnancy when using oral LNG EC; therefore, ulipristal acetate or copper intrauterine devices are preferable in this setting. Providers are often unaware of the range of EC options or are unsure of how to counsel patients regarding the access and use of EC. This article critically reviews current EC literature, summarizes recommendations, and provides guidance for counseling women about EC. Useful tips for health care providers are provided, with a focus on special populations, including breast-feeding women and those transitioning to long-term contraception after EC use. When treating women of reproductive age, clinicians should be prepared to counsel them about EC options, provide EC appropriately, and, if needed, refer for EC in a timely manner. PMID:27261868

    An online questionnaire was developed to explore respiratory protective device (RPD) prevalence in U.S. health care facilities. The survey was distributed to professional nursing society members in 2014 and again in 2015 receiving 322 and 232 participant responses, respectively. The purpose of this study was to explore if the emergency preparedness climate associated with Ebola virus disease changed the landscape of RPD use and awareness. Comparing response percentages from the two sampling time frames using bivariate analysis, no significant changes were found in types of RPDs used in health care settings. N95 filtering facepiece respirators continue to be the most prevalent RPD used in health care facilities, but powered air-purifying respirators are also popular, with regional use highest in the West and Midwest. Understanding RPD use prevalence could ensure that health care workers receive appropriate device trainings as well as improve supply matching for emergency RPD stockpiling. PMID:27462029

    A specific formulation has been approved for use in Italy for emergency contraception (EC) in 2000. As expected, marketing of this levonorgestrel (LNG) only formulation has been accompanied by an increased interest and, often, controversies leading to even strong opposition on the part of those ethically opposed to the use of any method that may act after fertilization. At present, several trials on the exact mechanism of action and safety have been conducted, giving good reason for simplifying access, providing it free or over the counter, in several European countries. EC, also known as ''the morning after pill'' or postcoital contraception, is a modality of preventing the establishment of an unwanted pregnancy after unprotected intercourse and thus, probably, of reducing the number of voluntary pregnancy terminations. Two different forms are available: the hormonal and the intrauterine. Hormonal estrogen only EC was first proposed in the 60s and in 1974 Yuzpe following his studies proposed for the first time his combined regimen, that showed better efficacy and lower side effects. More recently, a new regimen, consisting of LNG, administered alone at the dose of 1.5 mg, was introduced and found in clinical trials to be more effective than the Yuzpe regimen, if taken as early as possible, within 72 h, thereby replacing the latter in common use. Mechanism of action of both hormonal preparations used for EC is inhibiting or delaying ovulation, therefore a prefertilization action. No effect has been reported on the process of implantation nor on an ongoing pregnancy. The WHO have developed a third regimen based on the use of the selective progesterone receptor modulator (antiprogestin) Mifepristone and conducted trials with different dosages, reporting similar efficacy and safety compared to LNG. Intrauterine EC was first proposed by Lippes in 1976. It has the advantage of being effective if inserted within 5 days after unprotected intercourse and the disadvantage

    Full Text Available An emerging infection is defined as aninfection that has newly appeared in a population whilea re-emerging infection would be one that has existedin the past but its incidence has increased in recenttimes. The reasons for the emergence or reemergenceof an infection are not completely understood butthey are multifactorial and complex in the nature oftheir interactions. These factors may be related to theetiological organism, the host or the environment.Human activity appears to be a major driver. Malaysiahad to deal with outbreaks of several emerging infectionsover the last two decades. They include Nipah virusinfection, SARS and avian influenza. Infections likedengue, tuberculosis and leptospirosis are re-emergingin Malaysia. Both human activity and climatic changesappear to be key factors in the emergence and reemergenceof infections in Malaysia. Our countryneeds to put in place a comprehensive plan to meetthe challenge of emerging diseases. A multidisciplinaryapproach is required and the strategies involved shouldnot merely confined to medical and health strategies.

    Chemical crowd control agents are also referred to as riot control agents and are mainly used by civil authorities and government agencies to curtail civil disobedience gatherings or processions by large crowds. Common riot control agents used to disperse large numbers of individuals into smaller, less destructive, and more easily controllable numbers include chloroacetophenone, chlorobenzylidenemalononitrile, dibenzoxazepine, diphenylaminearsine, and oleoresin capsicum. In this paper, we discuss the emergency medical care needed by sufferers of acute chemical agent contamination and raise important issues concerning toxicology, safety and health. PMID:26658556

    2001-08-01

    Although the Chemical Weapons Convention prohibits the development, production, stockpiling, and use of chemical warfare agents (CWAs), the use of these agents persists due to their low cost, simplicity in manufacturing and ease of deployment. These attributes make these weapons especially attractive to low technology countries and terrorists. The military and the public at large require portable, fast, sensitive, and accurate analyzers to provide early warning of the use of chemical weapons. Traditional laboratory analyzers such as the combination of gas chromatography and mass spectroscopy, although sensitive and accurate, are large and require up to an hour per analysis. New, chemical specific analyzers, such as immunoassays and molecular recognition sensors, are portable, fast, and sensitive, but are plagued by false-positives (response to interferents). To overcome these limitations, we have been investigating the potential of surface-enhanced Raman spectroscopy (SERS) to identify and quantify chemical warfare agents in either the gas or liquid phase. The approach is based on the extreme sensitivity of SERS demonstrated by single molecule detection, a new SERS material that we have developed to allow reproducible and reversible measurements, and the molecular specific information provided by Raman spectroscopy. Here we present SER spectra of chemical agent simulants in both the liquid and gas phase, as well as CWA hydrolysis phase.

    An emerging infection is defined as an infection which has newly appeared in a population while a re-emerging infection is one which has existed in the past but its incidence is rapidly increasing. The reasons for the emergence and re-emergence of infections are not well understood but appear to be associated with factors that involve the pathogen, the host and the environment. These factors are often inter-related and act together in a complex manner to bring about changes in patterns of infection. Pathogens are extremely resourceful and possess mechanisms to adapt to new hosts and environments as well as to acquire new virulence traits. Host factors include herd immunity, social behaviour and demographics. Environmental factors like the climate, deforestation and new technologies have an impact on the emergence of infections. The challenge is to contain an infection when it emerges but more importantly to prevent its emergence in the first place. As the emergence of an infection is complex and multifactorial, a multidisciplinary approach is required. Health based strategies alone are insufficient. Social, economic and environmental measures and the political will to implement appropriate policies are equally important. PMID:10972048

Chemical terrorism is a broader phenomenon involving not only misuse of CWs but also of non-weaponised toxic compounds and intended strikes on industrial and social infrastructures with release of toxic, liquefied and inflammable chemicals. Nevertheless, the CWC is an important instrument in combating the most dangerous forms of international chemical terrorism. The effort of OPCW and mainly of SPs national authorities ensure that chemicals produced for peaceful purposes are not misused, provide some guarantees that terrorists will not be able to acquire or make their own CWs. That is why universality of the CWC and respective national implementation measures including comprehensive legislation are of utmost importance. The enforcement by all countries of the CWCs requirement to make the development, production, stockpiling, transfers and use of CWs illegal for anyone means that terrorist could be put on trial for violating the CWC. The OPCWs expertise and knowledge of CWs, verification regime and the system of assistance and protection under the CWC as a reflection of international co-operation are being put to use to prevent and respond to chemical terrorist strikes and thus considerably diminish their potential consequences. It can be added that pursuant to the UN SC Resolution 1540, all nations are obliged to take actions ensuring that non-State actors cannot develop, produce, use or trade CWs in the terms of the CWC. Current status of implementing the CWC is analysed with special emphasis on prevention of and response to terrorist chemical attacks.(author)

    Chemical leukoderma, often clinically mimicking idiopathic vitiligo and other congenital and acquired hypopigmentation, is an acquired form of cutaneous pigment loss caused by exposure to a variety of chemicals that act through selective melanocytotoxicity. Most of these chemicals are phenols and aromatic or aliphatic catechols derivatives. These chemicals, however, are harmful for melanocytes in individuals with an individual susceptibility. Nowadays, chemical leukoderma is fairly common, caused by common domestic products. The presence of numerous acquired confetti- or pea-sized macules is clinically characteristic of chemical leukoderma, albeit not diagnostic. Other relevant diagnostic elements are a history of repeated exposure to a known or suspected depigmenting agent at the sites of onset and a macules distribution corresponding to sites of chemical exposure. Spontaneous repigmentation has been reported when the causative agent is avoided; the repigmentation process is perifollicular and gradual, taking place for a variable period of weeks to months.

    2010-01-01

    Full Text Available Background: Most emergencies in Goa arise due to road traffic accidents and drowning, which have been compounded by the rise in number of recorded accidents in 2007 to be above 4000. It is believed that 11 people meet with an accident on Goa′s roads every day and this is expected to rise by 10% by next year. Similar is the case with drownings and other medical emergencies. We therefore aimed to conduct a cross-sectional survey of medical emergencies and identify various types of emergencies presenting to emergency departments. Materials and Methods: Using a stratified random sampling design, all emergencies presenting to the three government hospitals in Goa, which handle 90% of all emergencies currently, were studied on specially designed data sheets in order to collect data. Emergency medical technicians (ETs were placed in the Casualty Ward of the medical colleges and they recorded all emergencies on the data sheet. The collected data were then analyzed for stratification and mapping of emergencies. Results: GMC Hospital attended to majority of emergencies (62%, which were mainly of the nature of accidents or assaults (17% and fever related (17%. Most emergencies were noncritical and about 1% expired. Maximum emergencies also presented from Salcette and Bardez, and occurred among young males in the age group of 19-45 years. Males were also more prone to accidents while females had pregnancies as emergencies. Conclusion: Potential emergency services need to target young males with higher concentrations required in Salcette in South Goa and Bardez in North Goa.

    Emergency medical care in Ecuador is limited by geographic, economic, political, and infrastructural barriers. Afflictions of the developing world (eg, tropical infections and natural disasters) combine with ailments of the developed world (eg, trauma and cardiovascular disease) to mandate improved emergency medical systems. The nation has recently initiated FASBASE, a program dedicated to the enhancement of both prehospital and emergency department (ED) services. Furthermore, a dedicated residency program in Emergency and Disaster Medicine recently graduated its first class. Although more programs and funding are necessary to sustain the effort, Ecuador has begun to develop a modern emergency medical system. PMID:11555804

    2007-06-01

    There are so many emergency issues in our daily life. Such as typhoons, tsunamis, earthquake, fires, floods, epidemics, etc. These emergencies made people lose their lives and their belongings. Every day, every hour, even every minute people probably face the emergency, so how to handle it and how to decrease its hurt are the matters people care most. If we can map it exactly before or after the emergencies; it will be helpful to the emergency researchers and people who live in the emergency place. So , through the emergency map, before emergency is occurring we can predict the situation, such as when and where the emergency will be happen; where people can refuge, etc. After disaster, we can also easily assess the lost, discuss the cause and make the lost less. The primary effect of mapping is offering information to the people who care about the emergency and the researcher who want to study it. Mapping allows the viewers to get a spatial sense of hazard. It can also provide the clues to study the relationship of the phenomenon in emergency. Color, as the basic element of the map, it can simplify and clarify the phenomenon. Color can also affects the general perceptibility of the map, and elicits subjective reactions to the map. It is to say, structure, readability, and the reader's psychological reactions can be affected by the use of color.

  9. The role of civil organizations in monitoring the convention on the prohibition of the use, stockpiling, production and transfer of anti-personnel mines and on their destruction: a proposal for a cooperative compliance mechanism

    International Nuclear Information System (INIS)

    On December 2, 1997, approximately 100 government representatives will gather in Ottawa, Canada to sign a treaty banning the production, use or stockpiling of landmines. Both the speed with which this treaty was negotiated, and the extent to which it is a product of genuine cooperation between like-minded governments and non-governmental organizations (especially the International Campaign to Ban Landmines) make it a landmark document. Nonetheless, when the Convention on the Prohibition of the Use, Stockpiling, Production and Transfer of Anti-personnel Mines and on their Destruction (hereinafter, the APM Treaty) is reviewed in the context of other arms control agreements, it is clear that the 'compliance mechanism' is extremely soft. There are no sanctions against states who do not live up to the obligations they assume on signing the APM Treaty, although (under Article 8), States Parties may authorize a fact-finding mission to clarify a question regarding alleged non-compliance. This notwithstanding, the primary compliance mechanism is the provision that states voluntarily report once a year on measures they have taken to implement the treaty. (author)

  10. The formation and evolution of hydrogen-deficient post-AGB white dwarfs: the emerging chemical profile and the expectations for the PG1159-DB-DQ evolutionary connection

    CERN Document Server

    Althaus, L G; Panei, J A; Corsico, A H; García-Berro, E; Scoccola, C G

    2005-01-01

    This paper is designed to explore the formation and evolution of hydrogen-deficient post-AGB white dwarfs. To this end, we compute the complete evolution of an initially 2.7 M_sun star from the zero-age main sequence through the thermally pulsing and mass-loss phases to the white dwarf stage. Particular attention is given to the chemical abundance changes during the whole evolution. A time-dependent scheme for the simultaneous treatment of abundance changes caused by nuclear reactions, diffusive overshooting, salt fingers and convection is considered. We employed the double-diffusive mixing-length theory of convection for fluids with composition gradients (Grossman & Taam 1996). The study can therefore be considered as a test of its performance in low-mass stars. Also, time-dependent element diffusion for multicomponent gases is taken into account during the white dwarf evolution. The evolutionary stages corresponding to the last helium thermal pulse on the early white-dwarf cooling branch and the followi...

  11. Defining an emerging disease.

    Science.gov (United States)

    Moutou, F; Pastoret, P-P

    2015-04-01

    Defining an emerging disease is not straightforward, as there are several different types of disease emergence. For example, there can be a 'real' emergence of a brand new disease, such as the emergence of bovine spongiform encephalopathy in the 1980s, or a geographic emergence in an area not previously affected, such as the emergence of bluetongue in northern Europe in 2006. In addition, disease can emerge in species formerly not considered affected, e.g. the emergence of bovine tuberculosis in wildlife species since 2000 in France. There can also be an unexpected increase of disease incidence in a known area and a known species, or there may simply be an increase in our knowledge or awareness of a particular disease. What all these emerging diseases have in common is that human activity frequently has a role to play in their emergence. For example, bovine spongiform encephalopathy very probably emerged as a result of changes in the manufacturing of meat-and-bone meal, bluetongue was able to spread to cooler climes as a result of uncontrolled trade in animals, and a relaxation of screening and surveillance for bovine tuberculosis enabled the disease to re-emerge in areas that had been able to drastically reduce the number of cases. Globalisation and population growth will continue to affect the epidemiology of diseases in years to come and ecosystems will continue to evolve. Furthermore, new technologies such as metagenomics and high-throughput sequencing are identifying new microorganisms all the time. Change is the one constant, and diseases will continue to emerge, and we must consider the causes and different types of emergence as we deal with these diseases in the future. PMID:26470448

    S. N. Upadhyay

    2005-10-01

    Full Text Available Protection of biological systems against radiation damage is of paramount importance during accidental and unavoidable exposure to radiation. Several physico-chemical and biological factors collectively contribute to the damage caused by radiation and are, therefore, targets for developing radioprotectors. Work on the development of chemicals capable of protecting biological systemsfrom radiation damage was initiated nearly six decades ago with cysteine being the first molecule to be reported. Chemicals capable of scavenging free radicals, inducing oxygen depletion,antioxidants and modulators of immune response have been some of the radioprotectors extensively investigated with limited success. Mechanism of action of some chemical radioprotectors and their combinations have been elucidated, while further understanding is required in many instances. The present review elaborates on structure-activity relationship of some of the chemical radioprotectors, their evaluation, and assessment, limitation, and future prospects.

    Objective:To analyze the pros and cons of the US strategic national stockpile ( SNS) from the per-spective of the supply chain and to put forward suitable recommendations for China’s national emergency medicine system. Methods:Literature review and a comprehensive analysis have been utilized to understand the SNS supply chain model and its differences from the Chinese model. Results:From the perspective of the supply chain, the Unit-ed State’s storage of emergency medicine consists of the forward placement of push packages, managed inventory and purchase contracts. The deployment of logistics for emergency medicine must gain approval from the federal government’s “local-state-nation” system, and be conducted at a different time. To transmit information, a large da-tabase, simulation software, and a technical advisory response unit have been established to manage information flow to distribute medicine accurately and promptly. Conclusion:Given the experiences of supply chain management in the US SNS system, it is critical for China to improve the supply chain system of emergency medicine, define the institu-tions and responsibilities within the supply chain, establish disaster relief reserve of emergency medicine and adopt fourth-party logistics for emergency medicine in order to make the China’s emergency preparedness more systemized, standardized, and information-based.%目的:应用供应链管理理论分析美国国家医药品战略储备供应体系的优缺点,提出适用于我国国家应急医药品有效供应的建议。方法:通过文献研究和比较研究方法,了解美国应急医药品战略性国家储备体系的供应链模式与中国的差异性。结果:从供应链的视角,美国战略性国家储备对应急医药品主要采取“应急包预先储备”、“管理型库存”和“合同储备”的应急准备方式;对应急医药品的物流调运采取“地方-州-国家”申报审批管理和分时

    International Nuclear Information System (INIS)

    This bulletin contains information about activities of the Nuclear Regulatory Authority of the Slovak Republic (UJD). In this leaflet the role of UJD in Emergency planning and preparedness is presented. Emergency planning is the set of measures with the aim to find out and to get under control incidents and accidents at nuclear installation, and to find out and to master releases of radioactive materials into the environment. At the national level the Governmental National Emergency Commission for Radiation Accidents (KRH SR) is responsible for the emergency preparedness. This Commission consists of representatives from Ministry of Interior; Ministry of Health, Ministry of Economy, Ministry of Foreign Affairs, Ministry of Transportation, Posts, and Telecommunications, Ministry of Defence, and institutions participating in the emergency planning, including UJD. The UJD Chairman acts as Vice-chairman of this Commission. The assessment of the course and consequences of serious incident and accidents of nuclear installations is carried out by the Emergency Response Centre (KKC) established in 1995 by UJD, which manages its activities according to the Emergency Plan. The Emergency Plan of UJD is the set of technical and organisational measures with the aim to suggest optimal measures for protection of population and environment. In order to fulfill the tasks of the emergency planning UJD established its Emergency Response Group, which consists of four professional groups: (1) Reactor safety group; (2) Radiation protection group; (3) Logistic group; (4) Information group. UJD closely co-operates in the area of emergency planning on the international level. Agreements on co-operation have been signed with all neighbouring countries, International Atomic Energy Agency (IAEA), and other European countries. The emergency preparedness is verified by various types of emergency exercises at national or international level. UJD approved on-site emergency plans of nuclear

    Full Text Available Magnetic flux emergence from the solar convection zone into the overlying atmosphere is the driver of a diverse range of phenomena associated with solar activity. In this article, we introduce theoretical concepts central to the study of flux emergence and discuss how the inclusion of different physical effects (e.g., magnetic buoyancy, magnetoconvection, reconnection, magnetic twist, interaction with ambient field in models impact the evolution of the emerging field and plasma.

  4. Emergency air supply

    International Nuclear Information System (INIS)

    An air supply safety device is described which can operate in an hostile environment. The system ensures that should the ring mains supply or the operator's individual hose fail an emergency air supply is obtained from a compressed air bottle fed to the operator's face mask via a valve. The valve switches from mains/mask to emergency supply/mask when the mains pressure falls below the emergency supply pressure. (U.K.)

  7. Inspection of Emergency Arrangements

    International Nuclear Information System (INIS)

    The Working Group on Inspection Practices (WGIP) was tasked by the NEA CNRA to examine and evaluate the extent to which emergency arrangements are inspected and to identify areas of importance for the development of good inspection practices. WGIP members shared their approaches to the inspection of emergency arrangements by the use of questionnaires, which were developed from the requirements set out in IAEA Safety Standards. Detailed responses to the questionnaires from WGIP member countries have been compiled and are presented in the appendix to this report. The following commendable practices have been drawn from the completed questionnaires and views provided by WGIP members: - RBs and their Inspectors have sufficient knowledge and information regarding operator's arrangements for the preparedness and response to nuclear emergencies, to enable authoritative advice to be given to the national coordinating authority, where necessary. - Inspectors check that the operator's response to a nuclear emergency is adequately integrated with relevant response organisations. - Inspectors pay attention to consider the integration of the operator's response to safety and security threats. - The efficiency of international relations is checked in depth during some exercises (e.g. early warning, assistance and technical information), especially for near-border facilities that could lead to an emergency response abroad. - RB inspection programmes consider the adequacy of arrangements for emergency preparedness and response to multi-unit accidents. - RBs assess the adequacy of arrangements to respond to accidents in other countries. - The RB's role is adequately documented and communicated to all agencies taking part in the response to a nuclear or radiological emergency. - Inspectors check that threat assessments for NPPs have been undertaken in accordance with national requirements and that up-to-date assessments have been used as the basis for developing emergency plans for

    Full Text Available As urgências e as emergências hipertensivas são ocorrências clínicas que podem representar mais de 25% dos atendimentos a urgências médicas. O médico deverá estar habilitado a diferenciá-las, pois o prognóstico e o tratamento são distintos. Estima-se que 3% de todas as visitas às salas de emergência decorrem de elevações significativas da pressão arterial. Nos quadros relacionados a estes atendimentos, a emergência hipertensiva é a entidade clínica mais grave que merece cuidados intensivos. É caracterizada por pressão arterial marcadamente elevada e sinais de lesões de órgãos-alvo (encefalopatia, infarto agudo do miocárdio, angina instável, edema agudo de pulmão, eclâmpsia, acidente vascular encefálico. O objetivo deste estudo foi apresentar os principais pontos sobre o seu apropriado diagnóstico e tratamento. Foi realizada busca por artigos originais com os unitermos "crise hipertensiva" e "emergência hipertensiva" nas bases de dados Pubmed e MedLine nos últimos dez anos. As referências disponíveis destes artigos foram verificadas. Os artigos foram identificados e revisados e o presente estudo condensa os principais resultados descritos. Para esta revisão foram considerados ensaios clínicos em língua inglesa, estudos retrospectivos e artigos de revisão. A crise hipertensiva é a entidade clínica com aumento súbito da PA (> 180 x 120 mmHg, acompanhada por sintomas, que podem ser leves (cefaléia, tontura, zumbido ou graves (dispnéia, dor precordial, coma e até morte, com ou sem lesão aguda de órgãos-alvo. Se os sintomas forem leves e sem lesão aguda de órgãos alvos, define-se a urgência hipertensiva. Se o quadro clínico apresentar risco de vida e refletir lesão aguda de órgãos-alvo têm-se, então, a emergência hipertensiva.

The used method has been an analysis of the emergency surgical interventions more prevalent from February 2007 until October 2008 in our area (a regional hospital, and statistic of those nursing diagnosis that more frequently appeared in these interventions, the previous moment to the intervention and in addition common to all of them. The results were the following ones: the more frequent emergency operations were: Caesarean, ginecological curettage, laparotomy, help in risk childbirth, orthopaedic surgery and appendectomy. The more frequent nursing diagnosis in all the emergency operations at the previous moment of the intervention were: risk of falls, pain, anxiety, deficit of knowledge, risk of infection, movement stress syndrome, risk of hemorrhage, cutaneous integrity deterioration. The conclusion is that users present at the previous moment to an emergency operation several problems, which force to the emergency surgical ward nurse to the introduction of the nursing methodology, in order to identify the problems, to mark results and to indicate the interventions to achieve those results, besides in a humanitarian way and with quality. This can be obtained by performing a Structured Emergency Presurgical Visit.

    2016-04-01

    Acute medical care in hospital emergency departments has experienced rapid development in recent years and gained increasing importance not only from a professional medical point of view but also from an economic and health policy perspective. The present article therefore provides an update on the situation of emergency departments in Germany. Care in emergency departments is provided with an increasing tendency to patients of all ages presenting with varying primary symptoms, complaints, illnesses and injury patterns. In the process, patients reach the emergency department by various routes and structural provision. Cross-sectional communication and cooperation, prioritization and organization of emergency management and especially medical staff qualifications increasingly play a decisive role in this process. The range of necessary knowledge and skills far exceeds the scope of prehospital medical emergency care and the working environment differs substantially. In addition to existing structural and economic problems, the latest developments, as well as future proposals for the design of in-hospital emergency medical care in interdisciplinary emergency departments are described.

    This chapter discusses the fundamental ideas of how chemical networks are build, their strengths and limitations. The chemical reactions that occur in disks combine the cold phase reactions used to model cold molecular clouds with the hot chemistry applied to planetary atmosphere models. With a general understanding of the different types of reactions that can occur, one can proceed in building a network of chemical reactions and use it to explain the abundance of species seen in disks. One on-going research subject is finding new paths to synthesize species either in the gas-phase or on grain surfaces. Specific formation routes for water or carbon monoxide are discussed in more details. 13th Lecture of the Summer School "Protoplanetary Disks: Theory and Modelling Meet Observations"

    Travels, migration and circulation of goods facilitate the emergence of new infectious diseases often unrecognized outside endemic areas. Most of emerging infections are of viral origin. Muscular Sarcocystis infection, an acute illness acquired during short trips to Malaysia, and Chagas disease, a chronic illness with long incubation period found among Latin American migrants, are two very different examples of emerging parasitic diseases. The former requires a preventive approach for travelers going to Malaysia and must be brought forth when they return with fever, myalgia and eosinophilia, while the latter requires a proactive attitude to screen Latin American migrant populations that may face difficulties in accessing care.

  8. Gentilly - 2 NGS emergency plan

    International Nuclear Information System (INIS)

    Since 1970, HQ has developed nuclear emergency plan (NEP). Since that time there were been many changes to take into account operating experience: - After TMI accident (1979) for including the second unit on site: Gentilly 2; - After Chernobyl accident (1986) international feedbacks (Osart, Wano, Workshops...); - In 1995, Atomic Energy Control Board has performed audit. Our on-site EP has been ranked adequate. Main area requiring corrective actions is personnel training. The framework of regulations concerning the Gentilly 2 on-site NEP is based on ICRP, IAEA recommendations, at international level, and on Atomic Energy Control ACT and low of emergency measures at federal level, as well as, on law for the protection of persons and goods in case of emergency and low of environmental quality, at provincial level. Assuming the legal frame the NEP responsibilities are divided into on-site and off-site plans. Around G2 NPP there are two zones where the planning of protective actions must be done.. These zones were defined on the worst credible accident, as exposure planning zone (EPZ) and ingestion planning zone (IPZ). For EPZ an area of 7 km radius around NPP, a population of 15, 000 inhabitants and an industrial park (2-3, 000 workers) are assumed, while for IPZ an area of 70 km radius around NPP and a population of 560, 000 inhabitants are considered. Conventional (fire, chlorine, earthquake intrusion, medical incident, steam line rupture and flooding) and radiological (as external and internal) risks are taken into account and accordingly, the types of alert. The criteria to declare an emergency are: actions on alarm in control room; applications of EOP (Emergency Operations Procedures); witness examples (chemical spill, injured person); external notifications such as bomb threat, technological accident in Becancour industrial park, severe weather event, etc.... These criteria are specified for the cases of sector, site and general alert at level 1 and level 2

    Recent events, including the development of space tourism and commercial spaceflight, have increased the need for specialists in space medicine. With increased duration of missions and distance from Earth, medical and surgical events will become inevitable. Ground-based medical support will no longer be adequate when return to Earth is not an option. Pending the inclusion of sub-specialists, clinical skills and medical expertise will be required that go beyond those of current physician-astronauts, yet are well within the scope of Emergency Medicine. Emergency physicians have the necessary broad knowledge base as well as proficiency in basic surgical skills and management of the critically ill and injured. Space medicine shares many attributes with extreme conditions and environments that many emergency physicians already specialize in. This article is an introduction to space medicine, and a review of current issues in the emergent management of medical and surgical disease during spaceflight. PMID:17239732

  6. Emerging nuclear suppliers

    International Nuclear Information System (INIS)

    Efforts to prevent the spread of nuclear weapons have usually taken two tracks: The traditional approach has concentrated on a potential proliferant's perceived need for nuclear technology and possibly weapons; a second approach has targeted the supply side of the proliferation equation. The issue being examined in this book---emerging nuclear suppliers---falls between these two approaches. The potential proliferants have emerged as possible unrestrained suppliers of nuclear materials and technology. They threaten the entire nonproliferation regime by their exporting, not their weapons development. Analyzing and understanding the issue of emerging suppliers requires a refined definition of suppliers in general. The simple dichotomy of traditional versus emerging suppliers is no longer an adequate framework for analysis. Suppliers differ significantly in their technical capabilities, experience, and regime involvement, and these distinctions result in different nuclear export policies

  10. Global chemical pollution

    International Nuclear Information System (INIS)

    Over the past decade, public and governmental awareness of environmental problems has grown steadily, with an accompanying increase in the regulation of point sources of pollution. As a result, great strides have been made in cleaning polluted rivers and decreasing air pollution near factories. However, traditional regulatory approaches to environmental pollution have focused primarily on protecting the maximally exposed individual located in the immediate vicinity of the pollution source. Little attention has been given to the global implications of human production and use of synthetic chemicals. A consensus is emerging that even trace levels of environmental contamination can have potentially devastating environmental consequences. The authors maintain that ambient levels of pollution have risen to the point where human health is being affected on a global scale. Atmospheric transport is recognized as the primary mode of global distribution and entry into the food chain for organic chemicals. The following are examples of global chemical pollutants that result in human exposure of significant proportions: PCBs, dioxins, benzene, mercury and lead. Current regulatory approaches for environmental pollution do not incorporate ways of dealing with global pollution. Instead the major focus has been on protecting the maximally exposed individual. If we do not want to change our standard of living, the only way to reduce global chemical pollution is to make production and consumption processes more efficient and to lower the levels of production of these toxic chemicals. Thus the only reasonable solution to global pollution is not increased regulation of isolated point sources, but rather an increased emphasis on waste reduction and materials recycling. Until we focus on these issues, we will continue to experience background cancer risk in the 10-3 range

    The term ‘emerging contaminants’ is generally used to refer to compounds previously not considered or known to be significant to groundwater (in terms of distribution and/or concentration) which are now being more widely detected. As analytical techniques improve, previously undetected organic micropollutants are being observed in the aqueous environment. Many emerging contaminants remain unregulated, but the number of regulated contaminants will continue to grow slowly over th...

  14. An emergency exercise experience

    International Nuclear Information System (INIS)

    Emergency exercises are held to satisfy regulatory requirements and to hopefully improve emergency response. Unfortunately, simply satisfying the requirement is often the principle concern of those who plan drills. Argonne National Laboratory has detailed emergency plans, and each Division is required to have an emergency exercise at least once each year. However, the pressure to minimize time taken from research efforts reduces the value of many exercises. During the past year, the Health Physics Section at ANL made an effort to optimize the information and training obtained in the time allotted for a drill. The purpose of this presentation is to share our approach and the results of one experience with the anticipation that it will stimulate others to critically look at emergency exercises in their organizations. To be of value, an emergency response exercise must have clear objectives, allow organized reporting, contain a documented follow-up critique, and provide for correction of deficiencies in training and in the emergency plan. A mock criticality incident at ANL was used to test specific emergency response capabilities. The objectives of the 45 minute exercise included testing: (1) how well Health Physics, Fire Department, and Medical personnel would deal with the unexpected find of an unconscientious, contaminated person in a high radiation field; (2) the capability to quickly predict environmental radioactivity concentration for a surprise mock stack release of fission products; (3) the time required and accuracy for dose assessment from personnel dosimeters, criticality dosimeters and samples of blood and hair which were irradiated to known doses in the Argonne Janus reactor; (4) how well Health Physics personnel would identify and sort 'exposed persons' who had no dosimeters (small radioactive sources were hidden on select persons); and (5) how persons from the evacuated building would be accounted for. As a result of findings, special Health Physics

  15. Accident and emergency management

    International Nuclear Information System (INIS)

    There is an increasing potential for severe accidents as the industrial development tends towards large, centralised production units. In several industries this has led to the formation of large organisations which are prepared for accidents fighting and for emergency management. The functioning of these organisations critically depends upon efficient decision making and exchange of information. This project is aimed at securing and possibly improving the functionality and efficiency of the accident and emergency management by verifying, demonstrating, and validating the possible use of advanced information technology in the organisations mentioned above. With the nuclear industry in focus the project consists of five main activities: 1) The study and detailed analysis of accident and emergency scenarios based on records from incidents and rills in nuclear installations. 2) Development of a conceptual understanding of accident and emergency management with emphasis on distributed decision making, information flow, and control structure sthat are involved. 3) Development of a general experimental methodology for evaluating the effects of different kinds of decision aids and forms of organisation for emergency management systems with distributed decision making. 4) Development and test of a prototype system for a limited part of an accident and emergency organisation to demonstrate the potential use of computer and communication systems, data-base and knowledge base technology, and applications of expert systems and methods used in artificial intelligence. 5) Production of guidelines for the introduction of advanced information technology in the organisations based on evaluation and validation of the prototype system.

    The authors have characterized the optical output and Nd:glass pumping performance of large-scale (120-cm-long, 1.2-cm-inner-diam), metal-oxidizer chemical flashlamps supplied to us by G.T.E. Sylvania. The experimental results were obtained on the same test bed that was used to study xenon electrical flashlamps, as described in Dependence of Flashlamp Performance on Gas Fill and Bore Size, earlier in this section. The peak Nd inversion levels produced by the chemical lamps were less than or equal to 10% of those generated by a xenon lamp of similar size and energy loading. The Peak Nd levels are in good agreement with predictions for the pumping rates in Nd:glass by a blackbody at the color temperatures of 30000 to 50000C, which they have measured during the burn of the pyrotechnic lamp

  2. The Hanford Emergency Dosimetry System

    International Nuclear Information System (INIS)

    The Hanford project is a major atomic industrial complex, including nuclear reactors, fuel fabrication plants, chemical separation facilities and research laboratories. In addition to a surveillance and control programme for personnel radiation exposures, an emergency dosimetry system has been developed to provide rapid assessment of high dose rates, identification and control of employees, staff notifications and formation of staff emergency control centres, assessment of external exposure doses, evaluation of body burdens of radioactive materials, detection and control of radioactive environmental contamination and rapid exposure estimates for guidance of rescue and medical personnel. Primary reliance is placed upon the Hanford Film Badge Dosimeter, worn by all persons within controlled areas. The badge provides positive identification of the wearer and the film can be evaluated within 90 min. Separately, yet simultaneously, the remaining components of the badge can be processed for determinations of the neutron spectrum and dose in five energy groups, as well as provide an early estimate of the single collision neutron dose from a few to several thousand rads. Gamma-ray detection ranges from 20 mr to 1500 r from the film components to 10 to 10 000 r from tantalum shielded fluorods. The emergency system includes programmes that ensure employee understanding, monitor training and management co-operation for fast identification, control and segregation of affected employees. Monitoring personnel, using portable instrumentation, obtain on-site in vivo measurements of Na24 or measurements of activated indium foil in the film-badge dosimeter for preliminary dose estimates. The staff notification and operation of emergency control centres provide technical guidance and mobile supportive equipment including a mobile whole-body counter. Back-up laboratory facilities give supportive dosimetry through the analysis of blood for Na24 activation, P32 hair content

  3. Emergency planning zone reduction

    International Nuclear Information System (INIS)

    This paper describes the process used by a large industrial Department of Energy (DOE) site to communicate changing hazards to its stakeholders and install the confidence necessary to implement the resulting emergency planning changes. Over the last decade as the sites missions have shifted from full-scale production to a greater emphasis on environmental restoration and waste management, the off-site threat from its operations has substantially decreased. The challenge was to clearly communicate the reduced hazards, install confidence in the technical analysis that documented the hazard reduction, and obtain stakeholder buy-in on the path forward to change the emergency management program. The most significant change to the emergency management program was the proposed reduction of the sites Emergency Planning Zone (EPZ). As the EPZ is defined as an area for which planning is needed to protect the public in the event of an accident, the process became politically challenging. An overview of how the site initially approached this problem and then learned to more substantially involve the state and local emergency preparedness agencies and the local Citizens Advisory Board will be presented.

    The Convention on the Prohibition on the Development, Production, Stockpiling and Use of Chemical Weapons and on their Destruction, opened for signature, January 13, 1993, in Paris, France (CWC), is an unprecedented multilateral effort to eradicate an entire category of weapons of mass destruction and assure their continued absence through international verification. The CWC has been signed by over 150 nations, and is expected to enter into force in 1995. With its far-reaching system to verify compliance, the CWC presages a new foundation for international security based neither on fear nor on trust, but on the rule of law. A central feature of the CWC is that it requires each State Party to take implementing measures to make the Convention operative. The CWC goes beyond all prior arms control treaties in this regard. For this approach to succeed, and to inspire the eradication of other categories of mass destruction weaponry, coordination and planning are vital to harmonize CWC national implementation among States Parties. This Manual for National Implementation of the Chemical Weapons Convention is designed to assist States Parties, duly taking into account the distinctive aspects of their legal systems, in maximizing CWC enforcement consistent with their national legal obligations.

    1998-03-01

    Of all the buried landmine identification technologies currently available, sensing the chemical signature from the explosive components found in landmines is the only technique that can classify non-explosive objects from the real threat. In the last two decades, advances in chemical detection methods has brought chemical sensing technology to the foreground as an emerging technological solution. In addition, advances have been made in the understanding of the fundamental transport processes that allow the chemical signature to migrate from the buried source to the ground surface. A systematic evaluation of the transport of the chemical signature from inside the mine into the soil environment, and through the soil to the ground surface is being explored to determine the constraints on the use of chemical sensing technology. This effort reports on the results of simulation modeling using a one-dimensional screening model to evaluate the impacts on the transport of the chemical signature by variation of some of the principal soil transport parameters.

    In work [1], a surface embedded in flat ℝ 3 is associated to any three hermitian matrices. We study this emergent surface when the matrices are large, by constructing coherent states corresponding to points in the emergent geometry. We find the original matrices determine not only shape of the emergent surface, but also a unique Poisson structure. We prove that commutators of matrix operators correspond to Poisson brackets. Through our construction, we can realize arbitrary noncommutative membranes: for example, we examine a round sphere with a non-spherically symmetric Poisson structure. We also give a natural construction for a noncommutative torus embedded in ℝ 3. Finally, we make remarks about area and find matrix equations for minimal area surfaces.

    Phase transitions are well defined in physics through concepts such as spontaneous symmetry breaking, order parameter, entropy, and critical exponents. But emergence --- also exhibiting whole-part relations (such as top-down influence), unpredictability, and insensitivity to microscopic detail --- is a loosely-defined concept being used in many disciplines, particularly in psychology, biology, philosophy, as well as in physics[1,2]. I will review the concepts of emergence as used in the various fields and consider the extent to which the methods of phase transitions can clarify the usefulness of the concept of emergence both within the discipline of physics and beyond.1.

    The epidemiology of foodborne diseases is rapidly changing. Recently described pathogens, such as Escherichia coli O157:H7 and the epidemic strain of Salmonella serotype Typhimurium Definitive Type 104 (which is resistant to at least five antimicrobial drugs), have become important public health problems. Well-recognized pathogens, such as Salmonella serotype Enteritidis, have increased in prevalence or become associated with new vehicles. Emergence in foodborne diseases is driven by the same forces as emergence in other infectious diseases: changes in demographic characteristics, human behavior, industry, and technology; the shift toward a global economy; microbial adaptation; and the breakdown in the public health infrastructure. Addressing emerging foodborne diseases will require more sensitive and rapid surveillance, enhanced methods of laboratory identification and subtyping, and effective prevention and control.

    This presentation highlighted the findings of the 2009 review of the fuel cell industry and emerging markets as they appeared in Fuel Cell Today (FCT), a benchmark document on global fuel cell activity. Since 2008, the industry has seen a 50 per cent increase in fuel cell systems shipped, from 12,000 units to 18,000 units. Applications have increased for backup power for datacentres, telecoms and light duty vehicles. The 2009 review focused on emerging markets which include non-traditional regions that may experience considerable diffusion of fuel cells within the next 5 year forecast period. The 2009 review included an analysis on the United Arab Emirates, Mexico, Brazil and India and reviewed primary drivers, likely applications for near-term adoption, and government and private sector activity in these regions. The presentation provided a forecast of the global state of the industry in terms of shipments as well as a forecast of countries with emerging markets

    This paper will talk about the technologies that have been emerging over the 25 years since the Human Vision and Electronic Imaging conference began that the conference has been a part of, and that have been a part of the conference, and will look at those technologies that are emerging today, such as social networks, haptic technologies, and still emerging imaging technologies, and what we might look at for the future.Twenty-five years is a long time, and it is not without difficulty that we remember what was emerging in the late 1980s. Yet to be developed: The first commercial digital still camera was not yet on the market, although there were hand held electronic cameras. Personal computers were not displaying standardized images, and image quality was not something that could be talked about in a standardized fashion, if only because image compression algorithms were not standardized yet for several years hence. Even further away were any standards for movie compression standards, there was no personal computer even on the horizon which could display them. What became an emergent technology and filled many sessions later, image comparison and search, was not possible, nor the current emerging technology of social networks- the world wide web was still several years away. Printer technology was still devising dithers and image size manipulations which would consume many years, as would scanning technology, and image quality for both was a major issue for dithers and Fourier noise.From these humble beginnings to the current moves that are changing computing and the meaning of both electronic devices and human interaction with them, we will see a course through the changing technology that holds some features constant for many years, while others come and go.

  14. PFP Emergency Lighting Study

    International Nuclear Information System (INIS)

    NFPA 101, section 5-9 mandates that, where required by building classification, all designated emergency egress routes be provided with adequate emergency lighting in the event of a normal lighting outage. Emergency lighting is to be arranged so that egress routes are illuminated to an average of 1.0 footcandle with a minimum at any point of 0.1 footcandle, as measured at floor level. These levels are permitted to drop to 60% of their original value over the required 90 minute emergency lighting duration after a power outage. The Plutonium Finishing Plant (PFP) has two designations for battery powered egress lights ''Emergency Lights'' are those battery powered lights required by NFPA 101 to provide lighting along officially designated egress routes in those buildings meeting the correct occupancy requirements. Emergency Lights are maintained on a monthly basis by procedure ZSR-12N-001. ''Backup Lights'' are battery powered lights not required by NFPA, but installed in areas where additional light may be needed. The Backup Light locations were identified by PFP Safety and Engineering based on several factors. (1) General occupancy and type of work in the area. Areas occupied briefly during a shiftly surveillance do not require backup lighting while a room occupied fairly frequently or for significant lengths of time will need one or two Backup lights to provide general illumination of the egress points. (2) Complexity of the egress routes. Office spaces with a standard hallway/room configuration will not require Backup Lights while a large room with several subdivisions or irregularly placed rooms, doors, and equipment will require Backup Lights to make egress safer. (3) Reasonable balance between the safety benefits of additional lighting and the man-hours/exposure required for periodic light maintenance. In some plant areas such as building 236-Z, the additional maintenance time and risk of contamination do not warrant having Backup Lights installed in all rooms

    In most of today's emergency scenarios information plays a crucial role. Therefore, information has to be constantly collected and shared among all rescue team members and this requires new innovative technologies. In this paper a classification of emergency scenarios is presented, describing their special characteristics and common strategies employed by rescue units to handle them. Based on interviews with professional firefighters, requirements for new systems are listed. The goal of this article is to support developers designing new systems by providing them a deeper look into the work of first responders.

    A practical approach to a spill response, using a chemical/petroleum facility database, was discussed. In response to staff reduction and government changes, the Canadian Coast Guard (CCG) has developed an information database system entitled Port Emergency Response Information System (PERIS). Chemical and petroleum facilities have voluntarily provided information regarding past spill incidents. With this information, PERIS can address issues such as historical/corporate knowledge, training, and can focus on response capabilities of chemical and petroleum facilities. PERIS contains information about CCG equipment, has a spill database of past spills and has the capability to create new spill reports. PERIS can also act as a computerized training tool for new personnel. 15 figs

    Chemical burns are less frequent in routine practice, but could be very serious owing to the complexity and severity of their actions. Influx of casualty after a civil disaster (industrial explosion) or military (war or terrorism) is possible. The action of these agents could be prolonged and deep. In addition to the skin, respiratory lesions and general intoxication could be observed. The urgent local treatment rely essentially on prolonged washing. Prevention and adequate emergency care could limit the serious consequences of these accidents. Accidents (thermal burns or electrisations) due to high or low voltage electricity are frequent. The severity is linked with the affected skin but especially with internal lesions, muscular, neurological or cardiac lesions. All cases of electrisation need hospital care. Locally, the lesions are often deep with difficult surgical repairs and often require amputation. Aesthetic and functional sequela are therefore frequent. Secondary complications could appear several months after the accident: cataract, dysesthesia and hypotonia. PMID:12621941

  4. Applying radiological emergency planning experience to hazardous materials emergency planning within the nuclear industry

    International Nuclear Information System (INIS)

    The nuclear industry has extensive radiological emergency planning (REP) experience that is directly applicable to hazardous materials emergency planning. Recently, the Feed Materials Production Center near Cincinnati, Ohio, successfully demonstrated such application. The REP experience includes conceptual bases and standards for developing plans that have been tested in hundreds of full-scale exercises. The exercise program itself is also well developed. Systematic consideration of the differences between chemical and radiological hazards shows that relatively minor changes to the REP bases and standards are necessary. Conduct of full-scale, REP-type exercises serves to test the plans, provide training, and engender confidence and credibility

  6. Chemical spectroscopy

    International Nuclear Information System (INIS)

    The purpose of chemical spectroscopy with neutrons is to utilize the dependence of neutron scattering cross-sections on isotope and on momentum transfer (which probes the spatial extent of the excitation) to understand fundamental and applied aspects of the dynamics of molecules and fluids. Chemical spectroscopy is divided into three energy ranges: vibrational spectroscopy, 25-500 MeV, for which much of the work is done on Be-filter analyzer instruments; low energy spectroscopy, less than 25 MeV; and high resolution spectroscopy, less than 1 MeV, which typically is performed on backscattering spectrometers. Representative examples of measurements of the Q-depenence of vibrational spectra, higher energy resolution as well as extension of the Q-range to lower values at high energy transfers, and provisions of higher sensitivities in vibrational spectroscopy are discussed. High resolution, high sensitivity, and polarization analysis studies in low energy spectroscopy are discussed. Applications of very high resolution spectroscopy are also discussed

    The operation of liquefied natural gas (LNG) is pioneering within the PETROBRAS System. PETROBRAS Transporte - TRANSPETRO is going to operate two flexible LNG terminals, located in Ceara and Rio de Janeiro. In accordance with the Corporate Health, Safety and Environmental (HSE) Directive - Training, Education and Awareness, PETROBRAS Transporte S.A. - TRANSPETRO has prepared an action plan with the objective of ensuring the operational safety of the undertaking. Among other actions a training program for the emergency control of LNG will be inserted into the timetable. The above mentioned training program was held over a period of 20 hours, and was divided between theory and practice. In the theoretical part, the characteristics of the product, the history of accidents and the emergency response procedures were covered. In the practical part, 3000 gallons of LNG were utilized where the behavior of the product could be confirmed following a confined leak, thereby verifying the efficacy of the emergency control resources. The teaching process of the course was developed in the company through the preparation of specific procedures, emergency plans and the formation of internal instructors. (author)

  16. Paediatric emergencies: non-traumatic abdominal emergencies

    International Nuclear Information System (INIS)

    Presentation with acute abdominal pain or abdominal symptopathology is a very common cause of presentation of children to hospital. The causes are dependent in part on the age of the child, in part on the presence of previous surgery, and can be divided into those that relate to congenital abnormalities at whatever age they present, acquired disease and infection. Children, particularly young children are often poor historians, and therefore the clinical examination and the laboratory investigations are important in helping to come to a diagnosis. Primary imaging of abdominal emergencies in childhood is a radiograph of the abdomen, followed by ultrasound. Further imaging depends on the results of these studies. An ordered review of the abdomen radiograph is important if the salient features on X-ray are not to be missed. Practitioners should be competent with abdominal ultrasound in children and know where to seek the causes of disease, as these are different from those that are obtained in many instances in adults. Familiarity with the likely causes is important. The three commonest causes of acute abdominal pain in childhood are, in young infants, intussusception, appendicitis and mesenteric adenitis. In older children, inflammatory bowel disease and ovarian pathology are also included. This article details the approach to imaging and the salient features of some of the conditions. (orig.)

    Hanczyc, Martin M; Ikegami, Takashi

    2010-01-01

    We have developed a simple chemical system capable of self-movement in order to study the physicochemical origins of movement. We propose how this system may be useful in the study of minimal perception and cognition. The system consists simply of an oil droplet in an aqueous environment. A chemical reaction within the oil droplet induces an instability, the symmetry of the oil droplet breaks, and the droplet begins to move through the aqueous phase. The complement of physical phenomena that is then generated indicates the presence of feedback cycles that, as will be argued, form the basis for self-regulation, homeostasis, and perhaps an extended form of autopoiesis. We discuss the result that simple chemical systems are capable of sensory-motor coupling and possess a homeodynamic state from which cognitive processes may emerge. PMID:20586578

  3. How Emergent is Gravity?

    CERN Document Server

    Bhattacharya, Swastik

    2015-01-01

    General theory of relativity (or Lovelock extensions) is a dynamical theory; given an initial configuration on a space-like hypersurface, it makes a definite prediction of the final configuration. Recent developments suggest that gravity may be described in terms of macroscopic parameters. It finds a concrete manifestation in the fluid-gravity correspondence. Most of the efforts till date has been to relate equilibrium configurations in gravity with fluid variables. In order for the emergent paradigm to be truly successful, it has to provide a statistical mechanical derivation of how a given initial static configuration evolves into another. In this essay, we show that the energy transport equation governed by the fluctuations of the horizon-fluid is similar to Raychaudhuri equation and, hence gravity is truly emergent.

    2014-01-01

    Networks are mathematical structures that are universally used to describe a large variety of complex systems such as the brain or the Internet. Characterizing the geometrical properties of these networks has become increasingly relevant for routing problems, inference and data mining. In real growing networks, topological, structural and geometrical properties emerge spontaneously from their dynamical rules. Nevertheless we still miss a model in which networks develop an emergent complex geometry. Here we show that a single two parameter network model, the growing geometrical network, can generate complex network geometries with non-trivial distribution of curvatures, combining exponential growth and small-world properties with finite spectral dimensionality. In one limit, the non-equilibrium dynamical rules of these networks can generate scale-free networks with clustering and communities, in another limit planar random geometries with non-trivial modularity. Finally we find that these properties of the geo...

    LS Ullmann

    2008-01-01

    Full Text Available Hantaviruses belong to the Bunyaviridae family, which consists of vector-borne viruses. These viruses can provoke two infection types: hemorrhagic fever with renal syndrome (HFRS - which occurs in the Old World - and hantavirus cardiopulmonary syndrome (HCPS - an emergent zoonosis that can be found in many countries of the western hemisphere. Rodents are hantavirus reservoirs and each species seems to host a different virus type. Humans acquire the infection by inhaling contaminated aerosol particles eliminated by infected animals. The factors involved in the emergence of hantavirus infections in the human population include ecological modifications and changes in human activities. The most important risk factor is contact between man and rodents, as a result of agricultural, forestry or military activities. Rodent control remains the primary strategy for preventing hantavirus diseases, including via health education and hygienic habits.

  10. Pediatric oncologic emergencies

    International Nuclear Information System (INIS)

    Oncologic emergencies arise in three ways: disease or therapy induced cytopenias; a space occupying lesion causing pressure on or obstruction of surrounding tissues; or leukemia or tumors creating life-threatening metabolic or hormonal problems. Knowledge of presenting signs and symptoms of these emergencies are essential in pediatric oncologic nursing. Neutropenia opens the door for all manner of infections, but the most life threatening is septicemia progressing to shock. A variety of organisms can cause septic shock in the neutropenic patient, but episodes are most often due to gram-negative organisms and the endotoxins they release. Shock, while still compensated, may present with a elevated or subnormal temperature, flushed, warm, dry skin, widening pulse pressure, tachycardia, tachypnoea and irritability, but without medical intervention will progress to hypo tension, cool, clammy extremities, decreased urinary out- put, and eventually to bradycardia and cardiogenic shock. Another emergency in the cytopenia category is bleeding as a result of thrombocytopenia. Of greatest concern is intracranial hemorrhage that may occur at platelet counts of less than 5,000/mm3. Space-occupying lesions of the chest may produce superior vena cava syndrome (SVGS), pleural and pericardial effusions, and cardiac tamponade. SVGS is most often caused by non-Hodgkin's lymphoma (NHL) and presents as cough, hoarseness, dyspnea, orthopnea and chest pain. Signs include swelling, plethora, cyanosis, edema of conjunctiva and wheezing. Pleural and pericardial effusions present with respiratory or cardiac distress as does cardiac tamponade. Abdominal emergencies arise because of inflammation, mechanical obstruction, hemorrhage (often from steroid induced ulcers), and perforation. Pain is the most common presenting symptom, although vital sign alterations, fever, blood in vomitus or stool, abdominal distension and cessation of flatus are also important components of the acute abdomen

  19. Emergency core cooling device

    International Nuclear Information System (INIS)

    The present invention provides an emergency core cooling device without using a reactor core spray device, in which the reactor core of a BWR type reactor is cooled effectively and certainly by flooding of the reactor core. That is, the emergency core cooling device comprises a high pressure core water injection system as an emergency core cooling system (ECCS) for cooling the inside of the reactor core upon loss of coolants accident (LOCA). By means of the high pressure core water injection system, water is injected from a condensate storage vessel or a suppression pool to the inside of the reactor core shroud upon LOCA. Accordingly, the reactor core is cooled effectively by reactor core flooding. In this device, cooling water can be injected to the inside of the reactor core shroud by means of the high pressure core injection system upon LOCA in which the coolants are discharged from the outside of the reactor core shroud. On the other hand, upon LOCA in which the coolants are discharged from the inside of the reactor core shroud, the cooling water can be supplied to the reactor core by means of a cooling system upon reactor isolation which injects water to the outside of the reactor core or a low pressure water injection system.

    Elliott, William J

    2003-12-01

    Although they have become less common, hypertensive emergencies occur with an incidence of approximately 1 to 2/100,000 people per year. Our knowledge about this problem, its pathophysiology, risk factors, and appropriate treatment options has expanded during the past decade. A hypertensive emergency can be declared when an elevated blood pressure is associated with acute target-organ damage. Rapid evaluation and treatment (typically with an intravenously administered agent) should be instituted, usually in an intensive care unit setting, and the patient should be observed carefully during acute blood-pressure lowering. When properly treated, the prognosis for these patients is not nearly as dismal as it was more than 60 years ago, and the initial level of function of target organs (brain, heart, kidneys) is more indicative of an emergency than the actual level of blood pressure. Therapeutic options include the time-tested sodium nitroprusside (which has toxic metabolic products and is contraindicated in pregnancy, tobacco amblyopia, and Leber's optic atrophy); fenoldopam mesylate; and nicardipine. When properly treated, "malignant hypertension" need be considered malignant no longer. PMID:14594569

  2. Emergency reactor scram system

    International Nuclear Information System (INIS)

    The present invention provides an emergency reactor scram system capable of shut down a reactor safely upon occurrence of pump trip by improving a passive scram performance for an FBR-type reactor. Namely, a driving motor and an electric generator are connected to a main pump of a primary system. An AC/DC convertor is connected to the electric generator. A shielding plug is disposed to the upper end opening of a reactor container, a control rod drive mechanism is erected on the shielding plug, and an extension pipe is attached to scram magnets of the control rod drive mechanism. The extension pipe is connected to a control rod. The rotation of the shaft of the pump is used as a direct rotator to provide an integrated-type electric generator. The electric generator is electrically connected with the power source of a scram magnet of the emergency scram system. Accordingly, the control rod of the emergency scram system is automatically and rapidly inserted to the reactor core using the power source of the electric generator upon trip of the main pump thereby enabling to scram the reactor safely.

    Full Text Available Infectious causes should always be considered in all patients with uveitis and it should be ruled out first. The differential diagnosis includes multiple well-known diseases including herpes, syphilis, toxoplasmosis, tuberculosis, bartonellosis, Lyme disease, and others. However, clinicians should be aware of emerging infectious agents as potential causes of systemic illness and also intraocular inflammation. Air travel, immigration, and globalization of business have overturned traditional pattern of geographic distribution of infectious diseases, and therefore one should work locally but think globally, though it is not possible always. This review recapitulates the systemic and ocular mainfestations of several emergent infectious diseases relevant to the ophthalmologist including Rickettsioses, West Nile virus infection, Rift valley fever, dengue fever, and chikungunya. Retinitis, chorioretinitis, retinal vasculitis, and optic nerve involvement have been associated with these emergent infectious diseases. The diagnosis of any of these infections is usually based on pattern of uveitis, systemic symptoms and signs, and specific epidemiological data and confirmed by detection of specific antibody in serum. A systematic ocular examination, showing fairly typical fundus findings, may help in establishing an early clinical diagnosis, which allows prompt, appropriate management.

  4. Emergency Information Management System

    International Nuclear Information System (INIS)

    Information management is a key element for success for any planned activity. The same gains more importance in managing unplanned or off-normal activity. Availability of timely information is therefore a definite pre-requisite to success in handling the emergency/off-normal situations (mock or real). To meet this requirement of effectively managing various information being received during such conditions, Health Physics Unit at RAPS-5 and 6 has conceived, designed, developed and implemented a comprehensive integrated network based system, named Emergency Information Management System (ElMS). The system is highly scalable in terms of number of users and client systems. In addition, it may be extended to a decision support system which will assist the advisory groups in taking decision in light of incoming inputs/data. This system is highly helpful in organizing, presenting and displaying information in an orderly manner so as to help in handling, re-evaluation and reinforcing steps to mitigate the consequences and ensure optimum utilization of resources. The need of such a system has always been felt and its usage during recent wide scale Off-site emergency exercise at Rawatbhata Rajasthan Site has proven its advantages

  8. CHEMICAL EVOLUTION

    Energy Technology Data Exchange (ETDEWEB)

    Calvin, Melvin

    1965-06-01

    How did life come to be on the surface of the earth? Darwin himself recognized that his basic idea of evolution by variation and natural selection must be a continuous process extending backward in time through that period in which the first living things arose and into the period of 'Chemical Evolution' which preceded it. We are approaching the examination of these events by two routes. One is to seek for evidence in the ancient rocks of the earth which were laid down prior to that time in which organisms capable of leaving their skeletons in the rocks to be fossilized were in existence. This period is sometime prior to approximately 600 million years ago. The earth is believed to have taken its present form approximately 4700 million years ago. We have found in rocks whose age is about 1000 million years certain organic molecules which are closely related to the green pigment of plants, chlorophyll. This seems to establish that green plants were already fluorishing prior to that time. We have now found in rocks of still greater age, namely, 2500 million years, the same kinds of molecules mentioned above which can be attributed to the presence of living organisms. If these molecules are as old as the rocks, we have thus shortened the time available for the generation of the complex biosynthetic sequences which give rise to these specific hydrocarbons (polyisoprenoids) to less than 2000 million years.

  9. Industry's voluntary program: Community Awareness and Emergency Response Program and the Emergency Planning and Community Right-to-Know Act.

    Cooper, J S

    1990-10-01

    This paper describes the chemical industry's Community Awareness and Emergency Response (CAER) Program, and voluntary and mandatory actions by the chemical industry to comply with the major environmental legislation. The chemical industry started the voluntary CAER Program soon after the Bhopal Disaster in 1984; it is coordinated through the Chemical Manufacturer's Association. This program, which began in March 1985, is a long-term industry commitment to develop a community outreach program and to improve local emergency response planning. The Congress of the United States began, in 1985, to consider proposals for mandatory programs. This led to enactment of the Superfund Amendments and Reauthorization Act of 1986, known as SARA. A portion of this Act, entitled Title III is also known as the Emergency Planning and Community Right-to-Know Act. Although this legislation has many mandatory requirements, it should be emphasized that a significant degree of voluntary industrial participation is needed if the purposes of the statute are to be achieved. Title III has created an intricate and still evolving system that ties together the EPA, industrial plant managers, state emergency response commissions, local emergency planning committees and fire departments with jurisdiction over the facility. Each of these groups has a different role and responsibilities but must work cooperatively with other participants. Because of the intricate network of participants, the magnitude of the information flow, and the continuing evolution of the system, unique public relations problems exist in order to comply with Title III.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2274977

  12. Chemical Sensing for Buried Landmines - Fundamental Processes Influencing Trace Chemical Detection

    Energy Technology Data Exchange (ETDEWEB)

    PHELAN, JAMES M.

    2002-05-01

    Mine detection dogs have a demonstrated capability to locate hidden objects by trace chemical detection. Because of this capability, demining activities frequently employ mine detection dogs to locate individual buried landmines or for area reduction. The conditions appropriate for use of mine detection dogs are only beginning to emerge through diligent research that combines dog selection/training, the environmental conditions that impact landmine signature chemical vapors, and vapor sensing performance capability and reliability. This report seeks to address the fundamental soil-chemical interactions, driven by local weather history, that influence the availability of chemical for trace chemical detection. The processes evaluated include: landmine chemical emissions to the soil, chemical distribution in soils, chemical degradation in soils, and weather and chemical transport in soils. Simulation modeling is presented as a method to evaluate the complex interdependencies among these various processes and to establish conditions appropriate for trace chemical detection. Results from chemical analyses on soil samples obtained adjacent to landmines are presented and demonstrate the ultra-trace nature of these residues. Lastly, initial measurements of the vapor sensing performance of mine detection dogs demonstrates the extreme sensitivity of dogs in sensing landmine signature chemicals; however, reliability at these ultra-trace vapor concentrations still needs to be determined. Through this compilation, additional work is suggested that will fill in data gaps to improve the utility of trace chemical detection.

    The scope of French nuclear power led Electricite de France (EDF) to design standard products, manufactured in series but adaptable to different sites. Standardization is based on the decision on a single technology: pressurized water reactors (PWR). Thirty-four 900 MW and seventeen 1300 MW units are in operation on seventeen sites. The specific nature of French organization for normal operation and accident management results from equipment standardization and single licensee. This specificity is based on emergency plan standardization and highly structured national organization. Figs

    International Nuclear Information System (INIS)

    An attempt is made to identify the inhalation hazards associated with the over-exposure of workers and of the general public, following an accidental release of uranium hexafluoride. Maximum emergency concentrations are recommended for periods of 10, 30, and 60 minutes. The quantitative aspect of the assessment is considered in the context of the development of exposure standards for chemical substances and this facilitates the derivation of levels which are compatible with occupational and public health experience and attainable by management, and to which most workers and members of the general public may be exposed without adverse effect. The radiological implications are also considered. (author)

  4. Emergency preparedness and response

    International Nuclear Information System (INIS)

    After the Chernobyl accident, it became painfully obvious to the international community that there was an urgent need to establish a system for the coordination of international disaster assistance. It became the task of the United Nations Office for Disaster Relief (UNDRO) to develop such a system. The former UNDRO was subsumed into the Department of Humanitarian Affairs (DHA), established in January 1992 on the basis of UN General Assembly Resolution 46/182 adopted in December 1991, and the disaster relief system presently found in DHA is a further evolution of the system established by UNDRO. One particular importance in relation to nuclear accidents is the fact that UNDRO and the International Atomic Energy Agency (IAEA) signed a Memorandum of Understanding defining their respective responsibilities and the need for cooperation in case of accidents involving the unintentional release of nuclear radiation. In essence, the MOU makes it clear that the responsibilities of the IAEA, in connection with accidents at Nuclear Power Plants, related to the technical and radiological aspects, in particular to accident prevention, to the on-site preparedness, and to remedial measures within the 30-km zone outside the NPP. DHA's responsibilities, on the other hand, relate to the general preparedness and the rescue efforts outside the 30 km zone. In this respect, the preparedness and emergency response system is no different from the system employed in any other type of sudden-onset emergency

  6. Vascular retroperitoneal emergencies

    International Nuclear Information System (INIS)

    Ruptured abdominal aortic aneurysm is the major surgical emergency in the retroperitoneal compartment. Rupture of an abdominal aortic aneurysm is always fatal without urgent operative repair. Computed tomography is the reference standard for the diagnosis of ruptured abdominal aortic aneurysm in hemo-dynamically stable patients. At CT, the diagnosis is based on the combination of abdominal aortic aneurysm and extra-luminal retroperitoneal blood. Retroperitoneal hemorrhage usually demonstrates both iso-dense and hyperdense areas. In most cases hemorrhage is located in psoas compartments and perirenal space. In the case of ruptured abdominal aortic aneurysm other findings may be demonstrates both iso-dense and hyperdense areas. In the most cases hemorrhage is located in psoas compartments and perirenal space. In the case of ruptured abdominal aortic aneurysm other findings may be demonstrated such as focal interruption of the aortic wall and active extravasation of contrast media in the retroperitoneal compartments. Inflammatory abdominal aortic aneurysm, that may present as acute abdominal pain, should be recognized and differentiated from ruptured abdominal aortic aneurysm. Inflammatory abdominal aortic aneurysm is characterized by a fibrotic process around the abdominal aorta that may entrap adjacent structures such as ureters, duodenum and inferior vena cava. Aortic dissection, mycotic aneurysm, and inferior vena cava thrombosis are less common. Complications occurring after emergency aneurysm replacement are also considered.

  7. Planning for nuclear emergencies

    International Nuclear Information System (INIS)

    A properly developed and executed emergency plan represents an additional level of safety in dealing with potential accidents in nuclear facilities. A state-of-the-art review of the subject is presented which is based primarily on material presented by a variety of speakers during a short course held at the Harvard School of Public Health in May 1975. A certain degree of confusion has existed because of the multitude of federal and state agencies having responsibilities in this field; however, steps are being taken to correct this situation. Although updated Protective Action Guides for airborne releases have been published, similar action is needed for limitations on radionuclide intake via food and water. Indications are that, for a single puff type of airborne release, it may not be possible to evacuate the neighboring population within the short time span available to avoid exposure. For a longer term continuous type of airborne release, however, evacuation can be very useful. Still in need of further evaluation as an adjunct or alternative to evacuation is the use of protective shelter and/or radio-protective prophylaxis. Also in need of additional study and/or development are methods for assessing the nature and course of an accident, techniques for rapidly estimating the pathway of a release and anticipated population doses, assessment of the long-range implications of potential widespread radioactive contamination of land areas, and improvements in the capabilities of state and local agencies in providing radiological emergency response

  8. Communication system for emergency

    International Nuclear Information System (INIS)

    People are apprehensive that a strong earthquake with a magnitude of nearly 8 may occur in Tokai area. The whole area of Shizuoka Prefecture has been specified as the specially strengthened region for earthquake disaster measures. This report outlines the communication system for emergency with respect to atomic disaster caused by an earthquake. Previously, wireless receiving system is stationed in the whole area to simultaneously inform the related news to the residents and so, communications with them are possible at any time by using the system. Since mobile wireless receiving sets are stationed in all town halls, self defense organizations and all the places of refuge, mutual communications are possible. These communication system can be utilized for either earthquake or nuclear disaster. Further, Shizuoka general information network system has been established as a communication system for anti-disaster organization and a wireless network via a communication satellite, ''super bird'' has been constructed in addition to the ground network. Therefore, the two communication routes became usable at emergency and the systems are available in either of nuclear disaster or earthquake. (M.N.)

    Sepsis is defined as "life-threatening organ dysfunction caused by a dysregulated host-response to infection". Presence of organ dysfunction is associated with a mortality of 10% and higher in hospitalized sepsis patients.Introduction of standards in diagnosis and treatment of sepsis in intensive care units has not considerably reduced sepsis mortality. About 80% of patients with sepsis are transferred to intensive care units from usual care wards and emergency departments. Thus, it is tempting to speculate whether opportunities for further improvement of sepsis management exist outside of intensive care units. Performing a "quick sequential organ assessment" (qSOFA; two of following criteria have to be present: respiratory rate >22/min; sytolic blood pressure <100mmHg; altered mental status) supports to identify patients with suspicion of an infection and an increased risk of death within the hospital. Subsequent treatment according to current guidelines on sepsis management will reduce in-hospital mortality of sepsis patients. Indeed, we were able to show a substantial decrease of in-hospital mortality of about 20% in patients presenting with community acquired pneumonia to the emergency department.In summary, decision of further management of sepsis patients has to be done outside intensive care units at the time of initial presentation to professional care givers. Sepsis management in acute care settings should include a structured and standardized protocol to further improve survival in affected patients with even mild organ dysfunction. PMID:27464279

    Full text: The presentation is designed for individuals who are involved in therapeutic administration of radioactive material and the implementation of the radiation safety programme. The United States Nuclear Regulatory Commission (NRC) has regulatory authority over the medical use of by-product material and the radiation from by-product material. The presentation will address how the NRC regulates new medical uses (i.e. emerging technologies) used in radiation oncology that are too new to be covered in the current regulations. NRC's process that allows licensees to get approved for these emerging technologies until regulations are promulgated for the new modalities will be described. The presentation will also cover NRC's reporting requirements for medical events and other radiation safety-related incidents. Some examples of errors that have occurred for these new NRC-regulated activities will be provided. The root causes in these events will be identified to prevent similar additional incidents from occurring in other facilities performing the same type of therapy. (author)

    Gegenhuber, Alfons; Lenz, Kurt

    2003-12-01

    DEFINITION, PATHOPHYSIOLOGY, THERAPY: The hypertensive crisis is characterized by a massive, acute rise in blood pressure. Patients with underlying hypertensive disease usually have an increase in systolic blood pressure values > 220 mmHg and diastolic values > 120 mmHg. The severity of the condition, however, is not determined by the absolute blood pressure level but by the magnitude of the acute increase in blood pressure. Thus, in the presence of primarily normotensive baseline values (such as those in eclampsia), even a systolic blood pressure > 170 mmHg may lead to a life-threatening condition. The most important causes are non-compliance (reduction or interruption of therapy), inadequate therapy, endocrine disease, renal (vessel) disease, pregnancy and intoxication (drugs). The management of this condition greatly depends on whether the patient has a hypertensive crisis with organ manifestation (hypertensive emergency) or a crisis without organ manifestation (hypertensive urgency). By documenting the medical history, the medical status and by simple diagnostic procedures, the differential diagnosis can be established at the emergency site within a very short period of time. In the absence of organ manifestations (hypertensive urgency) the patient may have non-specific symptoms such as palpitations, headache, malaise and a general feeling of illness in addition to the increase in blood pressure. In a hypertensive urgency the patient's blood pressure should not be reduced within a few minutes but within a period of 24 to 48 hours. Such adjustment can be achieved on an out-patient basis, however, only if the patient can be followed up adequately for early detection of a renewed attack. In the absence of follow-up facilities, the patient's blood pressure should be reduced over a period of 4 to 6 hours, if necessary in an out-patient emergency service. While intravenous medication is given preference when a rapid effect is desired, oral medication may be used for

    Konsin, Larry S.

    2004-08-01

    Emergency Responders (Fire, Police, Medical, and Emergency Management) face a high risk of injury or death. Even before September 11, 2001, public and private organizations have been driven to better protect Emergency Responders through education, training and improved technology. Recent research on Emergency Responder safety, health risks, and personal protective requirements, shows infrared (IR) imaging as a critical need. Today"s Emergency Responders are increasingly challenged to do more, facing demands requiring technological assistance and/or solutions. Since the introduction of Fire Service IR imaging in the mid 1990s, applications have increased. Emergency response IR is no longer just seeing through smoke to find victims or the seat of a fire. Many more mission critical needs now exist across the broad spectrum of emergency response. At the same time, Emergency Responder injuries and deaths are increasing. The Office of Domestic Preparedness (ODP) has also recognized IR imaging as critical in protecting our communities -- and in preventing many of the injuries and deaths of Emergency Responders. Currently, only 25% of all fire departments (or less than 7% of individual firefighters) have IR imaging. Availability to Police, EMS and Emergency Management is even lower. Without ERCI, Emergency Responders and our communities are at risk.

  17. Emergent traffic jams

    Nagel, K; Nagel, Kai; Paczuski, Maya

    1995-01-01

    We study a single-lane traffic model that is based on human driving behavior. The outflow from a traffic jam self-organizes to a critical state of maximum throughput. Small perturbations of the outflow far downstream create emergent traffic jams with a power law distribution P(t) \\sim t^{-3/2} of lifetimes, t. On varying the vehicle density in a closed system, this critical state separates lamellar and jammed regimes, and exhibits 1/f noise in the power spectrum. Using random walk arguments, in conjunction with a cascade equation, we develop a phenomenological theory that predicts the critical exponents for this transition and explains the self-organizing behavior. These predictions are consistent with all of our numerical results.

  18. Communication in nuclear emergency

    International Nuclear Information System (INIS)

    In order to take protection measures smoothly at the time of emergency in nuclear power stations and others, it is necessary to prepare information communication facilities mutually among disaster prevention organizations including the state and information transmission network for residents in surrounding areas. The matters decided in ''the measures to be taken for the time being for the countermeasures to prevent disaster in nuclear power stations and others'' are shown. In order to avoid the congestion of communication, the exclusively used communication systems are adopted for disaster prevention organizations, in which facsimile is used to transmit graphic information. The data communication circuits for distributing SPEEDI are installed between Science and Technology Agency, Nuclear Power Safety Technology Center and respective prefectures. The routes, means and order of notices must be confirmed beforehand mutually among the related organizations.

    Obesity is rapidly becoming an emerging disease in developing countries due to the increasing westernization of societies and change in the lifestyle. The etiology of obesity is said to be multifactorial, with a combination of genetic and environmental factors. Literature has been extensively reviewed to provide a broad overview of obesity. Data for this review were obtained from original articles, review articles and textbooks. Internet search engines were also employed. The years searched were from 1993 to 2008. Obesity, classified in terms of the body mass index and the waist-hip ratio, has several associated co-morbidities such as diabetes mellitus, hypertension, degenerative osteoarthritis and infertility. In Nigeria, there is limited information on obesity. A literature review on obesity is necessary to improve the knowledge about obesity in developing countries, its prevention and its management.
