Nuclear power plant post-earthquake fires will cause not only personnel injury, severe economic loss, but also serious environmental pollution. For the moment, nuclear power is in a position of rapid development in China. Considering the earthquake-prone characteristics of our country, it is of great engineering importance to investigate the nuclear power plant post-earthquake fires. This article analyzes the cause, influential factors and development characteristics of nuclear power plant post-earthquake fires in details, and summarizes the three principles should be followed in fighting and preventing nuclear power plant post-earthquake fires, such as solving problems in order of importance and urgency, isolation prior to prevention, immediate repair and regular patrol. Three aspects were pointed out that should be paid attention in fighting and preventing post-earthquake fires. (authors)

Criticality and fire-fighting - Recent developments at Westinghouse, Springfields Fuels Limited

Fire-fighting advice in criticality-controlled areas has traditionally presented unique challenges to the nuclear industry, primarily because of the introduction of moderators / reflectors from water and foam and the potential rearrangement of materials. In an actual emergency, the decision to use water-based fire extinguishing methods is best influenced by a consensus between the criticality and fire specialists as part of the emergency planning process. A recent review of the fire-fighting arrangements at the site operated by Springfields Fuels Limited (SFL) in Preston in the United Kingdom has identified that more detailed guidance may be valuable relating to the specific areas and materials at risk, particularly to highlight the degree of risk and provide guidance on the risk of criticality if water-based fire extinguishing methods were deemed necessary. This has prompted consideration of a criticality 'Fire Tag' system, consisting of colour coded markers in the area (an immediate visual indicator of both the degree of risk and the appropriate fire-fighting response) and single sheet cards (specific guidance for the areas and materials at risk), with the process supported by appropriate training. The approach is currently being trialled on a small scale, and initial feedback from personnel has been positive. (authors)

On July 1, 2005 a fire occurred within an electrical switch room at Forsmark Nuclear Power Plant. At the evaluation of the incident it was identified that the pre-fire plans did not give sufficient information in order to make the appropriate decisions. Questions raised based on the incident are how decisions are made and orders are delegated with respect to the incident command, which fire fighting tactic should be used, which types of extinguishing media should be used, what are the risks with respect to safety of staff and safety of the reactor. Lessons learned from the fire at Forsmark were that pre-incident planning was at hand but the information was not sufficient to make the correct initial decisions that might be critical for life and property. One of the most crucial ingredients in all safety related work is to utilize previous experience in order to maintain a high degree of safety. Lessons learnt are also the foundation on which the ability to construct or create strong barriers against a certain fault phenomena, fault mechanism or type of initial event. In the case of nuclear processes, fire is considered as an important and critical initial event which has to be recognized in a number of cases in order to maintain a safe process. The likelihood for a fire to represent an initial event should not be underestimated and can therefore not be neglected, probabilistically or deterministically, unless the inherent safety systems can not control the event in an acceptable manner. Regardless of safety measures and lessons learnt from previous experiences in the construction and the operation of the nuclear facility, fires can occur. Previous experiences point out that process system, e.g. systems that are part of the turbine, are more frequently subject to fire incidents compared to ordinary safety systems. Fires in electrical components, often electrical cabinets, can be difficult to handle and to extinguish quickly. This report presents the background work

Subsurface coal fires destroy millions of tons of coal each year, have an immense impact to the ecological surrounding and threaten further coal reservoirs. Due to enormous dimensions a coal seam fire can develop, high operational expenses are needed. As part of the Sino-German coal fire research initiative "Innovative technologies for exploration, extinction and monitoring of coal fires in Northern China" the research team of University of Wuppertal (BUW) focuses on fire extinction strategies and tactics as well as aspects of environmental and health safety. Besides the choice and the correct application of different extinction techniques further factors are essential for the successful extinction. Appropriate tactics, well trained and protected personnel and the choice of the best fitting extinguishing agents are necessary for the successful extinction of a coal seam fire. The chosen strategy for an extinction campaign is generally determined by urgency and importance. It may depend on national objectives and concepts of coal conservation, on environmental protection (e.g. commitment to green house gases (GHG) reductions), national funding and resources for fire fighting (e.g. personnel, infrastructure, vehicles, water pipelines); and computer-aided models and simulations of coal fire development from self ignition to extinction. In order to devise an optimal fire fighting strategy, "aims of protection" have to be defined in a first step. These may be: - directly affected coal seams; - neighboring seams and coalfields; - GHG emissions into the atmosphere; - Returns on investments (costs of fire fighting compared to value of saved coal). In a further step, it is imperative to decide whether the budget shall define the results, or the results define the budget; i.e. whether there are fixed objectives for the mission that will dictate the overall budget, or whether the limited resources available shall set the scope within which the best possible results shall be

A physiological status monitor (PSM) has been embedded in a fire-resistant shirt. The purpose of this research study was to examine the ability of the PSM-shirt to accurately detect heart rate (HR) and respiratory rate (RR) when worn under structural fire fighting personal protective equipment (PPE) during the performance of various activities relevant to fire fighting. Eleven healthy, college-aged men completed three activities (walking, searching/crawling, and ascending/descending stairs) that are routinely performed during fire fighting operations while wearing the PSM-shirt under structural fire fighting PPE. Heart rate and RR recorded by the PSM-shirt were compared to criterion values measured concurrently with an ECG and portable metabolic measurement system, respectively. For all activities combined (overall) and for each activity, small differences were found between the PSM-shirt and ECG (mean difference [95% CI]: overall: -0.4 beats/min [-0.8, -0.1]; treadmill: -0.4 beats/min [-0.7, -0.1]; search: -1.7 beats/min [-3.1, -.04]; stairs: 0.4 beats/min [0.04, 0.7]). Standard error of the estimate was 3.5 beats/min for all tasks combined and 1.9, 5.9, and 1.9 beats/min for the treadmill walk, search, and stair ascent/descent, respectively. Correlations between the PSM-shirt and criterion heart rates were high (r = 0.95 to r = 0.99). The mean difference between RR recorded by the PSM-shirt and criterion overall was 1.1 breaths/min (95% CI: -1.9 to -0.4). The standard error of the estimate for RR ranged from 4.2 breaths/min (treadmill) to 8.2 breaths/min (search), with an overall value of 6.2 breaths/min. These findings suggest that the PSM-shirt provides valid measures of HR and useful approximations of RR when worn during fire fighting duties.

New technological developments in oil well fire fighting equipment and methods

Since Drake`s first oil well in 1859, well fires have been frequent and disastrous. Hardly a year has passed in over a century without a well fire somewhere in the world. In the 1920`s the classic method of fire fighting using explosives to starve the fire of oxygen was developed and it has been used extensively ever since. While explosives are still one of the most frequently used methods today, several other methods are used to supplement it where special conditions exist. Tunneling at an angle from a safe distance is used in some cases, especially where the fire is too hot for a close approach on the ground surface. Pumping drilling muds into a well to plug it is another method that has been used successfully for some time. Diverter wells are occasionally used, and sometimes simply pumping enough water on a well fire is sufficient to extinguish it. Of course, prevention is always the best solution. Many advances in blow-out prevention devices have been developed in the last 50 years and the number of fires has been substantially reduced compared to the number of wells drilled. However, very little in new technology has been applied to oil well fire fighting in the 1960s, 1970s, or 1980s. Overall technological progress has accelerated tremendously in this period, of course, but new materials and equipment were not applied to this field for some reason. Saddam Hussein`s environmental holocaust in Kuwait changed that by causing many people throughout the world to focus their creative energy on more efficient oil well fire fighting methods.

Three-dimensional tracking for efficient fire fighting in complex situations

Each year, hundred millions hectares of forests burn causing human and economic losses. For efficient fire fighting, the personnel in the ground need tools permitting the prediction of fire front propagation. In this work, we present a new technique for automatically tracking fire spread in three-dimensional space. The proposed approach uses a stereo system to extract a 3D shape from fire images. A new segmentation technique is proposed and permits the extraction of fire regions in complex unstructured scenes. It works in the visible spectrum and combines information extracted from YUV and RGB color spaces. Unlike other techniques, our algorithm does not require previous knowledge about the scene. The resulting fire regions are classified into different homogenous zones using clustering techniques. Contours are then extracted and a feature detection algorithm is used to detect interest points like local maxima and corners. Extracted points from stereo images are then used to compute the 3D shape of the fire front. The resulting data permits to build the fire volume. The final model is used to compute important spatial and temporal fire characteristics like: spread dynamics, local orientation, heading direction, etc. Tests conducted on the ground show the efficiency of the proposed scheme. This scheme is being integrated with a fire spread mathematical model in order to predict and anticipate the fire behaviour during fire fighting. Also of interest to fire-fighters, is the proposed automatic segmentation technique that can be used in early detection of fire in complex scenes.

2010-03-08

The University of Nevada, Reno Fire Science Academy (FSA) applied for grant funding to develop and deliver programs for municipal, rural, and volunteer firefighters. The FSA specializes in preparing responders for a variety of emergency events, including flammable liquid fires resulting from accidents, intentional acts, or natural disasters. Live fire training on full scale burnable props is the hallmark of FSA training, allowing responders to practice critical skills in a realistic, yet safe environment. Unfortunately, flammable liquid live fire training is often not accessible to municipal, rural, or volunteer firefighters due to limited department training budgets, even though most department personnel will be exposed to flammable liquid fire incidents during the course of their careers. In response to this training need, the FSA developed a course during the first year of the grant (Year One), Responding to Terrorist Incidents in Your Community: Flammable-Liquid Fire Fighting Techniques for Municipal and Rural Firefighters. During the three years of the grant, a total of 2,029 emergency responders received this training. In Year Three, two new courses, a train-the-trainer for Responding to Terrorist Incidents in Your Community and Management of Large-Scale Disasters for Public Officials were developed and pilot tested during the Real-World Disaster Management Conference held at the FSA in June of 2007. Two research projects were conducted during Years Two and Three. The first, conducted over a two year period, evaluated student surveys regarding the value of the flammable liquids training received. The second was a needs assessment conducted for rural Nevada. Both projects provided important feedback and a basis for curricula development and improvements.

The present study investigates the characteristics of obscuring media inside an optical smoke cell, which is a bench-scale testing facility for the evaluation of thermal imaging cameras used by fire fighters. Light extinction coefficient and visibility through the smoke cell is characterized by the measured laser transmittance. The laser transmittance along the axial direction of the smoke cell is relatively uniform at upper and lower part for various air/fuel volume flow rate. Contrast level based image quality of visible CCD camera through the smoke cell is compared with that of thermal imaging camera. The optical smoke cell can be used as well-controlled and effective laboratory-scale test apparatus to evaluate the performance of thermal imaging camera for fire fighting application

Climate change will lead to a dramatic increase in damage from forest fires in Europe by the end of this century. In the Mediterranean region, the average annual area affected by forest fires has quadrupled since the 1960s (WWF, 2012). The number of forest fires is also on the increase in Central and Northern Europe. The Austrian forest fire database shows a total of 584 fires for the period 2012 to 2014, while even large areas of Sweden were hit by forest fires in August 2014, which were brought under control only after two weeks of intense fire-fighting efforts supported by European civil protection modules. Based on these facts, the improvements in forest fire control are a major international issue in the quest to protect human lives and resources as well as to reduce the negative environmental impact of these fires to a minimum. Within this paper the development of a multi-functional airborne management support system within the frame of the Austrian national safety and security research programme (KIRAS) is described. The main goal of the developments is to assist crisis management tasks of civil emergency teams and armed forces in disaster management by providing multi spectral, near real-time airborne image data products. As time, flexibility and reliability as well as objective information are crucial aspects in emergency management, the used components are tailored to meet these requirements. An airborne multi-functional management support system was developed as part of the national funded project AIRWATCH, which enables real-time monitoring of natural disasters based on optical and thermal images. Airborne image acquisition, a broadband line of sight downlink and near real-time processing solutions allow the generation of an up-to-date geo-referenced situation map. Furthermore, this paper presents ongoing developments for innovative extensions and research activities designed to optimize command operations in national and international fire-fighting

In the German hard coal mining industry approximately since the 1970ies, automatically releasing stationary powder snow based fire fighting systems are built on diesel vehicles due to reasons of fire protection. These fire fighting systems are to recognize a developing fire by sensors and to extinguish the fire by an automatic output of a fire fighting agent with high rate (HRD = High Rate Discharge) into a closed engine compartment or within the range of hydraulics. Simultaneously with the releasing of the fire extinguishing system the engine of the vehicle is stop automatically. Due to the stationary fire fighting systems diesel vehicles are not classified with views of risk as fire load.

Yuan, Diping; Jin, Xuesheng; Zhang, Jin; Han, Dong

There's a growing need for fire departments to adopt a safe and fair method of training to ensure that the firefighting commander is in a position to manage a fire incident. Visual simulation training systems, with their ability to replicate and interact with virtual fire scenarios through the use of computer graphics or VR, become an effective and efficient method for fire ground education. This paper describes the system architecture and functions of a visual simulated training system of fire fighting on oil storage, which adopting Delat3D, a open source game and simulation engine, to provide realistic 3D views. It presents that using open source technology provides not only the commercial-level 3D effects but also a great reduction of cost.

Numerical modelling of the work of a pulsed aerosol system for fire fighting at the ignitions of liquid hydrocarbon fuels

2009-06-01

The work of a pulsed aerosol system for fire fighting is modelled, which is designed for fire fighting at oil storages and at the spills of oil products, whose vapors were modelled by gaseous methane. The system represents a device for separate installation, which consists of a charge of solid propellant (the gas generator) and a container with fine-dispersed powder of the flame-damper substance. The methane combustion was described by a one-stage gross-reaction, the influence of the concentration of vapors of the flame-damper substance on the combustion process was taken into account by reducing the pre-exponent factor in the Arrhenius law and was described by an empirical dependence. The computational experiment showed that the application of the pulsed aerosol system for fire fighting ensures an efficient transport of fine-dispersed aerosol particles of the flame-damping substance and its forming vapors to the combustion zone; the concentration of particles ensures the damping of the heat source.

Foam formation in low expansion fire fighting equipment

This thesis describes an investigation into the foam generation mechanisms involved in producing foam from a low expansion fire fighting branchpipe. The investigation was carried out using scale models of branchpipes, and a high-speed video camera was used to study the formation of the foam. The experiments provided evidence of three possible methods of bubble formation within this type of system: Stage 1 - Mixing within the branchpipe; Stage 2 - Air entrainment and bubble growth during the flight of the jet; Stage 3 - Aeration produced from the collision of the high speed jet onto a surface. Each stage is described in detail and the mechanism which has the greatest effect on the expansion ratio of the foam produced has been determined. The relevance of these findings to the design of branchpipes is discussed. (author)

Full Text Available Abstract Background Clinimetric data for the fire fighting simulation test (FFST, a new test proposed for the Workers' Health Surveillance (WHS of Dutch fire fighters, were evaluated. Methods Twenty-one fire fighters took the FFST three times with one and three weeks between testing. Clinimetric quality was determined by means of reliability, agreement and validity. For reliability and agreement, the intraclass correlation coefficient (ICC, and standard error of measurement (SEM, were analysed. For construct validity, the tests from 45 fire fighters were correlated with their own and their supervisors' rated work ability. Results The ICCs were 0.56 and 0.79 at the one-week and three-week test-retest periods, respectively. Testing times ranged from 9 to 17 minutes; the SEMs were 70 s at the one-week and 40 s at the three-week test-retest periods. The construct validity was moderate (-0.47 ≤ r ≤ -0.33; p Conclusions The FFST was reliable with acceptable agreement after three weeks. Construct validity was moderate. We recommend using FFST as a part of the WHS for Dutch fire fighters. It is advised that fire fighters should perform the FFST once as a trial before judging their performance in testing time during the second performance.

Autonomous mobile robot have been implemented to assist humans in their daily activity. Autonomous robots Have also contributed significantly in human safety. An example of the autonomous robot in the human safety sector is the fire fighting robot, which is the main topic of this paper. As an autonomous robot, the fire fighting robot needs a robust navigation ability to execute a given task in the shortest time interval. Wall-following algorithm is one of several navigating algorithm that simplifies this autonomous navigation problem. As a contribution, we propose two methods that could be combined to make the existing wall-following algorithm more robust. The combined wall-flowing algorithm will be compared to the original wall-following algorithm. By doing so, we could determine which method has more impact on the robot’s navigation robustness. Our goal is to see which method is more effective when combined with the wall-following algorithm.

Organic materials are a great source of energy and so biomass is in big demand. But wherever large amounts of wood, waste and straw are stored in huge silos, there is also a risk of smouldering fires and even explosions. Conventional methods are relatively ineffective at extinguishing fires such as these. But a new extinguishing system from Linde uses CO{sub 2} to effectively fight smouldering fires at the source.

In this paper, we present a millimeter wave radar system which will enhance the performance of infrared cameras used for fire-fighting applications. The radar module is compact and lightweight such that the system can be combined with inertial sensors and integrated in a hand-held infrared camera. This allows for precise distance measurements in harsh environmental conditions, such as tunnel or industrial fires, where optical sensors are unreliable or fail. We discuss the design of the RF front-end, the antenna and a quasi-optical lens for beam shaping as well as signal processing and demonstrate the performance of the system by in situ measurements in a smoke filled environment.

The study addresses a knowledge-gap in the long-term ecological consequences of fire and fire-fighting chemicals. Ten years after a prescribed fire and the application of three fire-fighting chemicals, their effects on the soil-plant system were evaluated. Five treatments were established: unburnt soils (US) and burnt soils treated with water alone (BS), foaming agent (BS+Fo), Firesorb (BS+Fi) and ammonium polyphosphate (BS+Ap). Soils (0-2 cm depth) and foliar material of shrubs (Erica umbellata, Pterospartum tridentatum and Ulex micranthus) and trees (Pinus pinaster) were analysed for total N, δ(15)N, and soil-available and plant total macronutrients and trace elements. Soil pH, NH₄(+)-N and NO₃(-)-N; pine basal diameter and height; and shrub cover and height were also measured. Compared with US plots, burnt soils had less nitrates and more Mo. Although differences were not always significant, BS+Ap had the highest levels of soil available P, Na and Al. Plants from BS+Ap plots had higher values of δ(15)N (P. pinaster and E. umbellata), P (all species), Na (P. tridentatum and U. micranthus) and Mg (E. umbellata and P. tridentatum) than other treatments; while K in plants from BS+Ap plots was the highest among treatments for P. pinaster and the lowest for the shrubs. Pines in US plots were higher and wider than in burnt treatments, except for BS+Ap, where the tallest and widest trees were found, although half of them were either dead (the second highest mortality after BS+Fi) or had a distorted trunk. BS+Ap was the treatment with strongest effects on plants, showing E. umbellata the lowest coverage and height, P. tridentatum the highest coverage, U. micranthus one of the lowest coverages and being the only treatment where Genista triacanthos was absent. Consequently, it is concluded that both fire and ammonium polyphosphate application had significant effects on the soil-plant system after 10 years. Copyright © 2015 Elsevier B.V.

Since the Browns Ferry incident, the specter of fires at nuclear plants has been the focus of attention by NRC, the utilities, and the public. There are sophisticated hardware and software available - in the form of fire-protection systems and equipment and training and fire-protection programs. Potential fire losses at nuclear faclities can be staggering. Thus, it behooves all those involved to maximize fire-protection security while simultaneously minimizing the chance of human error, which cancels out the effectiveness of the most up-to-date protective systems and devices

Anton, V.

1997-01-01

In this work a computer code structure for Fire Protection Measures (FPM) and Fire Fighting Capability (FFC) at Nuclear Power Plants (NPP) is presented. It allows to evaluate the category (satisfactory (s), needs for further evaluation (n), unsatisfactory (u)) to which belongs the given NPP for a self-control in view of an IAEA inspection. This possibility of a self assessment resulted from IAEA documents. Our approach is based on international experience gained in this field and stated in IAEA recommendations. As an illustration we used the FORTRAN programming language statement to make clear the structure of the computer code for the problem taken into account. This computer programme can be conceived so that some literal message in English and Romanian languages be displayed beside the percentage assessments. (author)

The development of a remotely-controlled valve to operate a fire hydrant is described. Assembled from off-the-shelf components, the prototype illustrates that a valve light enough to be handled by one man is possible. However, it does not have the ruggedness or reliability needed for actual fire-fighting operations. Preliminary testing by City of Tacoma fire department personnel indicates that the valve may indeed contribute significantly to fire-fighting efficiency

Normalization of water flow rate for external fire fighting of the buildings in settlements with zone water supply

Directory of Open Access Journals (Sweden)

Deryushev Leonid Georgievich

2014-12-01

Full Text Available In the article the requirements for fire safety assurance are justified for the objects, in which water is supplied with account for serial and parallel area zoning. In the process of zoning the district is segregated into such parts, for which head rate in any point of selection of water from network will not exceed 6 bar. In the current regulatory rules the requirements for the calculation of the costs of water points are stated, as well as in case of extinguishing fires at the sites with water-supply systems zones. It is recommended to analyze each zone of the system of water-supply separately, without interrelation with the common water feeders, water consumers and services of fire extinguishing. Such an approach to assign water discharge for fire extinguishing results in the decrease of fire safety of an object, deforms calculation technique of outside systems of water-supply of the similar-type objects located in different parts of the terrain. Taking the number of fires and water consumption for fire suppression by the number of residents in each zone, we thus underestimate the capacity of the pipeline system. It is offered to make changes in Norms and Standards in force on fire safety of settlements. The recommendations on regulation of the number of fires and water flow for fire fighting in residential objects with zoned systems of water-supply are formulated.

1988-03-01

From the nuclear and conventional fire safety audits of both Dutch nuclear power plants performed under supervision of the Nuclear Safety Inspectorate and the Inspectorate for the Fire Services it turns out that the fire safety is sufficient however amenable for improvement. Besides a detailed description of the method of examination, the study 'Fire Safety' contains the results of the audit and 14 respectively 15 recommendations for improvement of the fire safety in Dodewaard and Borssele. The suggested recommendations which are applicable to both power plants are the following: fire fighting training for operators and guards, a complete emergency ventilation system of the control room, increase in the number of detectors and alarms, an increase in the quantity of water available for high-pressure fire fighting, improvement of fire barriers between several redundancies of nuclear safety systems, an investigation and possible improvement of the heat and radiation protection offered by presently used fire fighting suits. For Dodewaard a closed emergency staircase in the reactor building (secondary containment) is deemed necessary for personnel emergency escape routes and continued fire fighting if required

Family Physician (FP) trainees are expected to be provided with high quality training in well organized practice settings. This study examines differences between FP trainers and non-trainers and their practices to see whether there are differences in trainers and non-trainers and in how their practices are organized and their services are delivered. 203 practices (88 non-training and 115 training) with 512 FPs (335 non-trainers and 177 trainers) were assessed using the "Visit Instrument Practice organization (VIP)" on 369 items (142 FP-level; 227 Practice level). Analyses (ANOVA, ANCOVA) were conducted for each level by calculating differences between FP trainees and non-trainees and their host practices. Trainers scored higher on all but one of the items, and significantly higher on 47 items, of which 13 remained significant after correcting for covariates. Training practices scored higher on all items and significantly higher on 61 items, of which 23 remained significant after correcting for covariates. Trainers (and training practices) provided more diagnostic and therapeutic services, made better use of team skills and scored higher on practice organization, chronic care services and quality management than non-training practices. Trainers reported more job satisfaction and commitment and less job stress than non-trainers. There are positive differences between FP trainers and non-trainers in both the level and the quality of services provided by their host practices. Training institutions can use this information to promote the advantages of becoming a FP trainer and training practice as well as to improve the quality of training settings for FPs.

Therefore it is necessary that these measurements have to be integrated into the activities mentioned above at an early stage in order to guarantee their effectiveness. With regard to fire accidents the statistics of the insurance companies concerned show that the damage caused increased in the last years mainly due to high concentration of material. Organization of fire prevention and fire fighting, reasons of fire break out, characteristics and behaviour of fire, smoke and fire detection, smoke and heat venting, fire extinguishers (portable and stationary), construction material in presence of fire, respiratory protection etc. will be discussed.

Forest Monitoring and Wildland Early Fire Detection by a Hierarchical Wireless Sensor Network

Directory of Open Access Journals (Sweden)

Antonio Molina-Pico

2016-01-01

Full Text Available A wildland fire is an uncontrolled fire that occurs mainly in forest areas, although it can also invade urban or agricultural areas. Among the main causes of wildfires, human factors, either intentional or accidental, are the most usual ones. The number and impact of forest fires are expected to grow as a consequence of the global warming. In order to fight against these disasters, it is necessary to adopt a comprehensive, multifaceted approach that enables a continuous situational awareness and instant responsiveness. This paper describes a hierarchical wireless sensor network aimed at early fire detection in risky areas, integrated with the fire fighting command centres, geographical information systems, and fire simulators. This configuration has been successfully tested in two fire simulations involving all the key players in fire fighting operations: fire brigades, communication systems, and aerial, coordination, and land means.

On September 26, 2003, a magnitude (M) 8.3 offshore earthquake struck Hokkaido, Japan. The earthquake and ensuing tsunami injured hundreds of people and resulted in significant damage to port and coastal communities. Immediately following the earthquake, a major fire occurred at an oil storage facility of a refinery (Idematsu Kosan Company Ltd) located in the west part of Tomakomai, a Pacific coast city in southern Hokkaido. Idemitsu Kosan Company is the second largest oil refinery in Japan, with a capacity of 140,000 barrels per day (bpd) in Tomakomai. Forty five of the 105 oil storage tanks were damaged following the earthquake and resulted in release of petroleum naphtha, which ignited accidentally. The first fire was reported immediately after the earthquake on 26 September 2003 and was extinguished after 7 hours. The second fire occurred on 28 September and lasted for 44 h. More than three hundred fireman and about one hundred fire engines were brought from several prefectures by air carriers to extinguish the fire. More than 130,000 L of fire fighting foams (FFF) was delivered to extinguish these fires and at least 40,000 L was used. Detailed information regarding the type of FFF used was not available, but aqueous film forming foams (AFFF) have been used in the control of fuel-related fires. Perfluorooctane sulfonate (PFOS) and related perfluorinated acids are a component of AFFF. The issue of environmental pollution by perfluorinated compounds (PFCs) including perfluorinated carboxylates and sulfonates has received much attention in the last four years. PFCs possess unique physicochemical properties and exhibit a wide range of volatility/ water solubility depending on the functional group. Environmental dynamics of PFCs is complex due to their unique characteristics and to their release from multitude of sources with various compositions. Previous studies have reported on environmental contamination by PFCs due to accidental release of AFFF. Large amount of

Malet, JC.

1989-01-01

This document gives a general idea of how one may deal with the safety of an installation in case of a sodium leak generating either a sodium pool fire, or a sodium spray fire, or a combined sodium fire, and in case of a sodium leak either with or without fire and/or any aggravating phenomenon such as aerosols or sodium-concrete reactions, for example. This paper describes the means used to reduce fire consequences. These means are either design codes used for dimensioning premises with their ventilation system or for defining a course of action to be taken in case of fire, or equipment and components (fire fighting equipment, detection devices, etc.) used to prevent or to fight fires, or finally, to repair the installation after a fire, the latter operation including the processing of the residues.

Context: Very few women have leadership positions in athletic training (ie, head athletic training positions) in intercollegiate athletics. Research exists on the barriers to attaining the role; however, our understanding about the experiences of those currently engaged in the role is limited. Objective: To examine the experiences of female head athletic trainers as they worked toward and attained the position of head athletic trainer. Design: Qualitative study. Setting: National Collegiate Athletic Association Division I setting. Patients or Other Participants: Eight female athletic trainers serving in the role of head athletic trainer participated in our study. The mean age of the participants was 45 ± 12 years, with 5 ± 1.5 years of experience in the role of head athletic trainer and 21 ± 10 years of experience as athletic trainers. Data Collection and Analysis: We conducted phone interviews with the 8 participants following a semistructured format. Interviews were transcribed verbatim and analyzed following a general inductive approach as described by Thomas. To establish credibility, we used a peer reviewer, member checks, and multiple-analyst triangulation. Results: Six major themes emerged from our analysis regarding the experiences of female head athletic trainers. Opportunities to become a head athletic trainer, leadership qualities, and unique personal characteristics were discussed as factors leading to the assumption of the role of the head athletic trainer. Where women hold back, family challenges, and organizational barriers speak to the potential obstacles to assuming the role of head athletic trainer. Conclusions: Female head athletic trainers did not seek the role, but through persistence and encouragement, they find themselves assuming the role. Leadership skills were discussed as important for success in the role of head athletic trainer. Life balancing and parenting were identified as barriers to women seeking the role of head athletic

Review of the IAEA fire symposium

International Nuclear Information System (INIS)

Fischer, J.

1991-01-01

The IAEA Symposium on Fire Protection and Fire Fighting in Nuclear Installations covered a large scope in the field in order to provide the opportunity for screening all aspects of present technology, research and development, standardization, licensing and fire fighting practices. Although application to any nuclear facility was within its scope, the majority of presentations concerned nuclear power plants. The approach to fire protection is the classical one in all plant designs: reduction of fire loads, appropriate zoning, manual and automatic extinguishment. However, methods of analysis and consequence prediction are changing. Computerized fire modelling is becoming a powerful tool in this area; probabilistic analytical methods are being improved, though they are not yet used widely for fire hazards. Differences in opinion were revealed in the definition of barrier resistance, the prediction of cable insulation behaviour and the optimal design of extinguishing systems. Greater international co-operation, especially in these areas, may be a good way of optimizing results with limited resources. Discussion contributions showed interest in exchange of experience in more specialized topics and encouraged the IAEA to increase its activity in the area of fire protection. (orig.)

Regardless of the fire prevention measures which are taken, plant experience indicates that fires will occur in a nuclear power plant. When a fire occurs, the plant staff must handle the fire emergency. Pre-fire planning is a method of developing detailed fire attack plans and salvage operations to protect equipment from damage due to fire and fire fighting operations. This paper describes the purpose and use of a pre-fire plan to achieve these goals in nuclear power plants

Short- and medium-term effects of three fire fighting chemicals on the properties of a burnt soil

International Nuclear Information System (INIS)

Couto-Vazquez, A.; Gonzalez-Prieto, S.J.

2006-01-01

The impact of three fire fighting chemicals (FFC) on 11 chemical soil properties and on soil recovery (0-2 cm depth) was evaluated 1, 30, 90 and 365 days after a prescribed fire. Five treatments were considered: unburnt soil (United States) and burnt soil with 2 l m -2 of water alone (BS) or mixed with the foaming agent Auxquimica RFC-88 at 1% (BS + Fo), Firesorb at 1.5% (BS + Fi) and FR Cross ammonium polyphosphate at 20% (BS + Ap). At t = 1 day, soil pH increases in the order US 15 N decreased in all burnt soils (significatively in BS + Ap) due to the inputs of 15 N depleted ashes from leguminous vegetation. Compared with US, soil δ 15 N increased significantly in all burnt plots between t = 90 days (30 days in BS + Ap) and t = 365 days, suggesting a medium-term fire-triggered increment of N outputs ( 15 N depleted). As is habitually the case, there was a transient post-fire increase of NH 4 + -N levels (significative for BS + FFC plots) that lasted for 30 (BS, BS + Fo and BS + Fi) to 90 days (BS + Ap). The high initial NH 4 + -N levels in BS + Ap (200x that of US; 9-18x those of BS, BS + Fo and BS + Fi), and its persistence can delay the post-fire vegetation recovery due to the toxicity of NH 4 + to seeds and seedlings. NO 3 -N levels changed significantly only in BS + Ap between t = 30 and t = 90 days due to the nitrification of its large NH 4 + -N pool. Except in BS + Ap, whose soil P levels were 70-140x (t = 1 days) and 10-20x (t = 365 days) higher than in the other treatments, available P content in BS and BS + FFC was not significatively higher than in US. The concentrations of available cations in BS and BS + FFC were higher (not always significatively, except for K) than in US until t = 90 days, likely due to ashes- and FFC-derived cations. Contrarily to divalent cations, monovalent cations (more soluble and easily leached) decreased slowly until t = 90 days

Dobes, P.; Danihelka, P.; Janickova, S.; Marek, J.; Bernatikova, S.; Suchankova, J.; Baudisova, B.; Sikorova, L.; Soldan, P.

2012-04-01

As shown at several case studies, waste waters from extinguishing of industrial fires involving hazardous chemicals could be serious threat primary for surrounding environmental compartments (e.g. surface water, underground water, soil) and secondary for human beings, animals and plants. The negative impacts of the fire waters on the environment attracted public attention since the chemical accident in the Sandoz (Schweizerhalle) in November 1986 and this process continues. Last October, special Seminary on this topic has been organized by UNECE in Bonn. Mode of interaction of fire waters with the environment and potential transport mechanisms are still discussed. However, in many cases waste water polluted by extinguishing foam (always with high COD values), flammable or toxic dangerous substances as heavy metals, pesticides or POPs, are released to surface water or soil without proper decontamination, which can lead to environmental accident. For better understanding of this type of hazard and better coordination of firemen brigades and other responders, the ecotoxicity of such type of waste water should be evaluated in both laboratory tests and in water samples collected during real cases of industrial fires. Case studies, theoretical analysis of problem and toxicity tests on laboratory model samples (e.g. on bacteria, mustard seeds, daphnia and fishes) will provide additional necessary information. Preliminary analysis of waters from industrial fires (polymer material storage and galvanic plating facility) in the Czech Republic has already confirmed high toxicity. In first case the toxicity may be attributed to decomposition of burned material and extinguishing foams, in the latter case it can be related to cyanides in original electroplating baths. On the beginning of the year 2012, two years R&D project focused on reduction of extinguish waste water risk for the environment, was approved by Technology Agency of the Czech Republic.

Personal trainers play an integral role in the day-to-day operation of the facilities in which they work. Research has identified a number of qualities and competencies necessary to be an effective exercise leader, but there is little scholarly work addressing clients' attitudes related to the performance of personal trainers. Utilizing focus group methodology, female clients of personal trainers were recruited to provide viewpoints related to the desirable qualities of personal trainers, as well as opinions regarding trainer certification and academic preparation. Responses of the participants were transcribed, coded, and analyzed for themes. Four global themes emerged: Selection Rationale, Personal Trainer Rationale, Loyalty Rationale and Negative Characteristics. Selection Rationale consisted of qualities that influence a client's decision to hire a particular trainer (e.g., physique, results observed in other clients, social skills). Personal Trainer Rationale referred to the clients' reasons (e.g., frustration with current fitness level) for hiring a specific trainer. Loyalty Rationale referred to the credentials of a personal trainer that solidify the client/trainer relationship and Negative Characteristics referred to qualities considered unethical or unprofessional. The results suggest that undergraduate exercise science programs should devote additional time toward the development of future fitness trainers' affective qualities and that clients' would benefit from information about the credentials of personal trainers.

Fire prevention, fire fighting and fire automatic alarms are three aspects which be included in fire protection system in nuclear power plants. The fire protection system can protect personnel, equipment etc in the fire, so their performance will have a direct influence on the safe operation in nuclear power plants. The disabled accidents caused by aging have happened continuously with the extension of time in the fire protection system, which is the major security risk during the running time in nuclear power plants. In view of the importance of fire protection system and the severity of aging problems, the aging are highly valued by the plant operators and related organizations. Though the feedback of operating experience in nuclear power plant, the impact of the fire-fighting equipment aging on system performance and reliability be assessed, the aging sensitive equipment be selected to carry out the aging analysis and to guide the management and maintenance to guarantee the healthy operation in life time of fire protection system in nuclear power plant.

Full Text Available Continuing education and training provides a means to improve performance among health care professionals (HCP. Research shows, however, that continuing professional education activities have inconsistent effects on HCP competence, performance, and patient health outcomes. Furthermore, the trainer’s role as a facilitator of knowledge translation (KT has been understudied. To understand how clinical trainers support their trainees in translating what they learned into practice, we conducted 16 in-depth interviews with expert trainers. These interviews yielded a variety of KT-enhancing strategies, including tailoring training activities to their trainees’ needs. In addition, participants recommended trainers familiarize themselves with their trainees’ work environments, be able to identify their knowledge deficits, and devote time to provide trainees with post-training support. Creating an effective training, one that leads to transfer, requires active planning, communication, and command of the training topic by skilled trainers.

Weather Observation Systems and Efficiency of Fighting Forest Fires

Science.gov (United States)

Khabarov, N.; Moltchanova, E.; Obersteiner, M.

2007-12-01

Weather observation is an essential component of modern forest fire management systems. Satellite and in-situ based weather observation systems might help to reduce forest loss, human casualties and destruction of economic capital. In this paper, we develop and apply a methodology to assess the benefits of various weather observation systems on reductions of burned area due to early fire detection. In particular, we consider a model where the air patrolling schedule is determined by a fire hazard index. The index is computed from gridded daily weather data for the area covering parts Spain and Portugal. We conduct a number of simulation experiments. First, the resolution of the original data set is artificially reduced. The reduction of the total forest burned area associated with air patrolling based on a finer weather grid indicates the benefit of using higher spatially resolved weather observations. Second, we consider a stochastic model to simulate forest fires and explore the sensitivity of the model with respect to the quality of input data. The analysis of combination of satellite and ground monitoring reveals potential cost saving due to a "system of systems effect" and substantial reduction in burned area. Finally, we estimate the marginal improvement schedule for loss of life and economic capital as a function of the improved fire observing system.

Methods and means for reducing pressure in systems for fire fighting and water spraying in mines

Kozlyuk, A I; Grin' , G V; Yushchenko, Yu N

1986-01-01

Valves are evaluated used in water systems for fire fighting and dust suppression in underground black coal mines in the USSR. Specifications of the KR-2, the KR-3 and the R-86 pressure-reducing valves used in deep mines are analyzed. The valves are characterized by low reliability, low capacity and low pressure reducing range. Therefore groups (parallel arrangement) of pressure-reducing valves are used. Using valve groups increases equipment cost. The pressure-reducing systems should consist of no more than 2 valves. The VNIIGD Institute developed the RKGD pressure-reducing valve with the following specifications: inlet pressure 6.87 MPa, outlet pressure from 0.98 to 2.45 MPa, water discharge 100 m/sup 3//h). The RKGD valves are characterized by high reliability but extremely high weight. Therefore, the VNIIGD Institute developed a modified version of pressure-reducing valve, called the PRK (with maximum inlet pressure of 5 MPa, outlet pressure ranging from 0.5 to 1.5 MPa, water discharge 80 m/sup 3//h and weighing 5 kg). Design of the PRK pressure-reducing valve is shown.

1985-01-01

'Fire countermeasures in radiation handling facilities' published in 1961 is still widely utilized as a valuable guideline for those handling radiation through the revision in 1972. However, science and technology rapidly advanced, and the relevant laws were revised after the publication, and many points which do not conform to the present state have become to be found. Therefore, it was decided to rewrite this book, and the new book has been completed. The title was changed to 'Fire and earthquake countermeasures in radiation handling facilities', and the countermeasures to earthquakes were added. Moreover, consideration was given so that the book is sufficiently useful also for those concerned with fire fighting, not only for those handling radiation. In this book, the way of thinking about the countermeasures against fires and earthquakes, the countermeasures in normal state and when a fire or an earthquake occurred, the countermeasures when the warning declaration has been announced, and the data on fires, earthquakes, the risk of radioisotopes, fire fighting equipment, the earthquake counter measures for equipment, protectors and radiation measuring instruments, first aid, the example of emergency system in radiation handling facilities, the activities of fire fighters, the example of accidents and so on are described.

Organizing for Emergencies - Issues in Wildfire Fighting in Croatia

Directory of Open Access Journals (Sweden)

Robert Fabac

2015-01-01

Full Text Available Croatia's accession to the European Union implies inevitable changes in the national emergency management system. New requirements for adjustment in accordance with the EU standards and practices also apply to the fire-services organization. Harmonious functioning of a large number of relatively autonomous organizations related to the National Protection and Rescue Directorate necessitates clear decision-making authority and coordination mechanisms as well as a high level of interoperability and core competencies development. This paper gives an overview of the Croatian fire protection organization along with its accompanying legislation, followed by an analysis of identified problems, especially those concerning fighting of wildfire. In our research a survey questionnaire comprised of Likert-scale items was used to assess the attitudes and experiences of trained fire department members. The respondents reported a relatively low evaluation of effectiveness and appropriateness of the following key fire service attributes: organizational structure, legislation and firefighting logistics support. From the obtained results guidelines can be drawn for possible redesign of the emergency management organization, especially those concerning the fire protection service.

Models for fleet sizing and localization of fire-fighting for attendance to accidents in platforms; Modelos para dimensionamento de frota e localizacao de embarcacoes fire-fighting para atendimento a acidentes em plataformas

Energy Technology Data Exchange (ETDEWEB)

Medina, Afonso Celso; Brinati, Marco Antonio [Sao Paulo Univ., SP (Brazil). Escola Politecnica

The increasing degree of use of maritime resources claims the establishment of a modern protection and assistance system to prevent and control maritime accidents. The usual safety systems for maritime accidents, generally, have the aid of specialized fleets in the attendance. This work presents models to determine the location and the profile of a specialized fleet for fire fighting, in order to guarantee the adequate attendance to expected accidents in a marine oil field. To modelling the problem, two means of analysis are considered: a deterministic model of integer programming and a probabilistic model. Considering the geographic location and the size of platforms as input data, the deterministic model establishes, among the available vessels, the fleet profile and location in order to minimize the fleet cost assuring the attendance to each platform within the standard requirements. The probabilistic model starts from a given solution for the fleet profile and vessel location and, by means of estimating the utilization factors of each vessel, proposes possible improvements in the fleet location, in order to maximize the probability of attending the accidents. A simulation model was elaborated to validate the results from the probabilistic model. The obtained results indicate the usefulness of every model, not only to a rational location problem solution, but also, for the analysis of the operational fleet performance.

Based on the application of comprehensive heat balance calculations the whole parameters like geometry, fire load, ventilation conditions etc. of a German PWR were covered. A practical design procedure based on diagrams was developed whereby separate diagrams for oil and cable fires were presented. A probabilistic safety concept was employed as to account for the specific variations of fire parameters as fire load and area, ventilation condition, rate of burning. With respect to the frequency of fire occurrences and the impact of fire fighting measures on the spread of fires latest statistical data of a special BMI investigation were used. (orig./HP) [de

Full Text Available Abstract Background This study investigates approaches for translating evidence-based knowledge for use by fitness trainers. Specific questions were: Where do fitness trainers get their evidence-based information? What types of interventions are effective for translating evidence-based knowledge for use by fitness trainers? What are the barriers and facilitators to the use of evidence-based information by fitness trainers in their practice? Methods We describe a systematic review of studies about knowledge translation interventions targeting fitness trainers. Fitness trainers were defined as individuals who provide exercise program design and supervision services to the public. Nurses, physicians, physiotherapists, school teachers, athletic trainers, and sport team strength coaches were excluded. Results Of 634 citations, two studies were eligible for inclusion: a survey of 325 registered health fitness professionals (66% response rate and a qualitative study of 10 fitness instructors. Both studies identified that fitness trainers obtain information from textbooks, networking with colleagues, scientific journals, seminars, and mass media. Fitness trainers holding higher levels of education are reported to use evidence-based information sources such as scientific journals compared to those with lower education levels, who were reported to use mass media sources. The studies identified did not evaluate interventions to translate evidence-based knowledge for fitness trainers and did not explore factors influencing uptake of evidence in their practice. Conclusion Little is known about how fitness trainers obtain and incorporate new evidence-based knowledge into their practice. Further exploration and specific research is needed to better understand how emerging health-fitness evidence can be translated to maximize its use by fitness trainers providing services to the general public.

Full-scale horizontal cable-tray tests: Fire-propagation characteristics

International Nuclear Information System (INIS)

Anon.

1991-01-01

At the Fermi National Accelerator Center (Fermilab), as at any high-energy physics laboratory, the experimental program depends on complex arrays of equipment that require years to assemble and place in service. These equipment arrays are typically located in enclosed tunnels or experimental halls and could be destroyed by rapidly propagating, uncontrolled fire. Cable trays, both vertical and horizontal, are an integral and ubiquitous component of these installations. Concurrently, throughout industry and within the professional fire-fighting community, there has been concern over the flammability and fire propagation characteristics of electrical cables in open cable trays. While some information was available concerning fire propagation in vertical cable trays, little was known about fires in horizontal cable trays. In view of the potential for loss of equipment and facilities, not to mention the programmatic impact of a fire, Fermilab initiated a program of full-scale, horizontal cable-tray fire tests to determine the flammability and rate of horizontal fire propagation in cable-tray configurations and cable mixed typical of those existing in underground tunnel enclosures and support buildings as Fermilab. This series of tests addressed the effects of ventilation rates and cable-tray fill, fire-fighting techniques, and the effectiveness and value of automatic sprinklers, smoke detection, and cable-coating fire barriers in detecting, controlling, or extinguishing a cable-tray fire. Detailed descriptions of each fire test, including sketches of cable-tray configuration and contents, instrumentation, ventilation rates, Fermilab Fire Department personnel observations, photographs, and graphs of thermocouple readings are available in a report of these tests prepared by the Fermilab Safety Section

Every year, hundreds of thousands of hectares of European forests are destroyed by fires. Due to the particular topography, landscape and demographic distribution in Europe (very different from typical scenarios of China, USA, Canada and Australia), rapidity in fire sighting is still the determining factor in limiting damages to people and goods. Moreover, the possibility of early fire detection means also potentially to reduce the size of the event to be faced, the necessary fire fighting resources and, therefore, even the reaction times. In such a context, integration of satellite technologies (mainly high temporal resolution data) and traditional surveillance systems within the fire fighting procedures seems to positively impact on the effectiveness of active fire fighting as demonstrated by recent experiences over Italian territory jointly performed by University of Basilicata, IMAA-CNR and Local Authorities. Real time implementation was performed since 2007, during fire seasons, over several Italian regions with different fire regimes and features, in order to assess the actual potential of different satellite-based fire detection products to support regional and local authorities in efficiently fighting fires and better mitigating their negative effects. Real-time campaigns were carried out in strict collaboration with end-users within the framework of specific projects (i.e. the AVVISA, AVVISTA and AVVISA-Basilicata projects) funded by Civil Protection offices of Regione Lombardia, Provincia Regionale di Palermo and Regione Basilicata in charge of fire risk management and mitigation. A tailored training program was dedicated to the personnel of Regional Civil Protection offices in order to ensure the full understanding and the better integration of satellite based products and tools within the existing fire fighting protocols. In this work, outcomes of these practices are shown and discussed, especially highlighting the impact that a real time satellite

Spontaneous uncontrolled coal seam fires are a well known phenomenon that causes severe environmental problems and severe impact on natural coal reserves. Coal fires are a worldwide phenomenon, but in particular in Xinjiang, that covers 17.3 % of Chinas area and hosts approx 42 % of its coal resources. In Xinjiang since more than 50 years a rigorous strategy for fire fighting on local and regional scale is persued. The Xinjiang Coalfield Fire Fighting Bureau (FFB) has developed technologies and methods to deal with any known fire. Many fires have been extinguished already, but the problem is still there if not even growing. This problem is not only a problem for China due to the loss of valuable energy resources, but it is also a worldwide threat because of the generation of substantial amounts of greenhouse gases. Through the FFB, China is struggling to overcome this, but the activities could be much enhanced by the continuation of the already successful conjoint operations. The last ten years have seen two successful cooperative projects between China and Germany on the field of coal-fire fighting, namely the German Technical Cooperation Project on Coal Fire in Xinjiang and the Sino-German Coal Fire Research Initiative funded by the corresponding ministeries of both countries. A persistent task in the fire fighting is the identification and supervision of areas with higher risks for the ignition of coal fires, the exploration of already ignited fire zones to extinguish the fires and the monitoring of extinguished fires to detect as early as possible process that may foster re-ignition. This can be achieved by modeling both the structures and the processes that are involved. This has also been a promising part of the past cooperation projects, yet to be transformed into a standard application of fire fighting procedures. In this contribution we describe the plans for a new conjoint project between China and Germany where on the basis of field investigations and

Insurance companies represent not only damage compensation systems, but also a worldwide financial services operating compensation of damages against the insurance premium. The insurance industry has adapted itself to the industrial development. The comprehensive risk management was supplemented increasingly. Especially in the case of damage prevention and fire fighting, the insurance industry falls back on the comprehensive risk management. The fire insurance companies have learned to evaluate fire risks more technically and economically and to impact the design concepts of fire fighting. Under these conditions, in the case of major industrial risks the fire insurance companies are willing to provide an extensive insurance coverage.

The fire brigade renovates

CERN Multimedia

2002-01-01

The new fire engine at CERN's Fire Station. A shiny brand-new fire engine is now attracting all the attention of the members of CERN's fire brigade. Since the beginning of last week this engine has taken over from an 18-year-old one, which has now been 'retired' from service. This modern vehicle, built in Brescia, Italy, is much lighter and more powerful than the old one and is equipped to allow the fire service to tackle most call-outs without the support of at least one other vehicle, as is currently necessary. The new fire engine is designed to transport six fire-fighters, 2000 litres of water, and is equipped not only for fire fighting actions but also to respond initially to any other kind of call-out, such as traffic accidents, chemical incidents, pollution, lightning, etc. It goes almost without saying that it is provided with the most modern safety measures, a low centre of gravity, as well as a special chassis and a combination pump (low and high pressure), which improve the safety and performance ...

Combustible, porous materials may self-ignite during their storage time in silos as a result of internal heating. The self-ignition process may be slow, and it results in smouldering fires that are extremely difficult to extinguish. Suitable means to fight the smouldering fire were studied both theoretically and experimentally. General heat and mass transfer equations for porous media subject to fires and suppression were written. The equations together with dimensional analysis revealed critical parameters, like the grain size and moisture content, affecting the combustion and suppression process, but they also revealed the complexity of the problem. Experimental results of over 50 tests with varying combustibles and suppression agents were used as the basis for proposed qualitative guidelines on how to fight a smouldering silo fire. Among the potential gaseous agents, CO{sub 2} was found to be the most efficient one. Low expansion foam was also found to be a potential candidate, but its applicability requires further confirmation. Quantifying the guidelines requires a whole new study on the detection of a smouldering fire. The same detection system should be capable of monitoring the suppression process and - most importantly - verifying the extinguishment. (orig.) 46 refs.

An empirical test of Lanchester's square law: mortality during battles of the fire ant Solenopsis invicta

Science.gov (United States)

Plowes, Nicola J.R; Adams, Eldridge S

2005-01-01

Lanchester's models of attrition describe casualty rates during battles between groups as functions of the numbers of individuals and their fighting abilities. Originally developed to describe human warfare, Lanchester's square law has been hypothesized to apply broadly to social animals as well, with important consequences for their aggressive behaviour and social structure. According to the square law, the fighting ability of a group is proportional to the square of the number of individuals, but rises only linearly with fighting ability of individuals within the group. By analyzing mortality rates of fire ants (Solenopsis invicta) fighting in different numerical ratios, we provide the first quantitative test of Lanchester's model for a non-human animal. Casualty rates of fire ants were not consistent with the square law; instead, group fighting ability was an approximately linear function of group size. This implies that the relative numbers of casualties incurred by two fighting groups are not strongly affected by relative group sizes and that battles do not disproportionately favour group size over individual prowess.

Educational CPD: how UK GP trainers develop themselves as teachers.

Science.gov (United States)

Waters, Mark; Wall, David

2007-09-01

There is little in the literature giving the perspective of UK General Practice (GP) trainers on their development as teachers. What motivates GP trainers develop themselves as teachers? What obstacles to their professional development do GP trainers perceive? A questionnaire to all GP trainers in the West Midlands Deanery in 2004. 360/444 (81%) questionnaires were returned. 56.6% of GP trainers had another educational role in addition to training GP Registrars in the practice. 15.8% of trainers possessed an educational qualification. 13 had completed a Certificate in Medical Education and 28 were engaged in study towards that qualification. Trainers wanted more time to spend on their development as teachers than they presently have, and would then be interested in a wider variety of learning methods. However, 56.6% of trainers would still not choose to undertake a university-accredited course. Female GP trainers perceived more difficulty in obtaining protected time for their development as teachers (Educational CPD) (p = 0.021), were significantly less sure of their partners' support for this development (p = 0.033), and were more likely to agree with trainers undertaking a Certificate in Medical Education (p = 0.003). Having an additional educational role did not affect trainers' ability to take protected time, but significantly increased the amount of time aspired to (p = 0.005). Nothing made more difference to trainers' perception of their ability to undertake Educational CPD than did the perceived attitude of their partners. Educational CPD was very important to GP trainers, but getting protected time was difficult. Consideration of the needs and opinions of partners was a very strong barrier to trainers taking sufficient protected time. Given more available time, GP trainers would be more likely to consider gaining academic qualifications in education. However, this was not be something that all trainers wanted.

Each summer fires rage through European forests, burning hundreds of thousands of hectares per year, as a result of the many (up to 60000) forest fires that usually occur annually in Europe. Fires can threaten public health and safety, destroy property and cause economic damages. Despite of their medium extension (the average burnt area is less than 6 ha), much smaller if compared with other regions like the USA and Canada, the number of simultaneous active fires in Europe can be very high, fomented by weather conditions that, especially in summer times and for countries of South Europe, are particularly favourable to a rapid and dramatic development of flames. Fires still are not only a social problem, but also an environmental emergency, producing a continuous impoverishment of forests and possibly indirectly triggering other natural hazards (e.g. making slopes, without the trees action, more prone to landslides). Additionally, there is a general concern about the loss of biodiversity and the contribution to land degradation that fires may cause. Earth Observation satellite systems have been largely tested for fire detection and monitoring from space. Their spectral capability, synoptic view and revisit times can offer an added value in the operational use not only in real time, during fires fighting activities, but also in near-real or delay time during the phases of risk management and mitigation. However, the practice of an actual operational use of satellite products by end-users is still not usual at European level. This work is based on the experience carried out jointly by CNR-IMAA and the National Civil Protection Department (DPC), in the framework of a five-year agreement in which the operational use of an Earth observation satellite system for fires spotting and monitoring is tested. Satellite-based products, developed not only for detecting fires but also for continuously monitoring their evolution in time domain, have been provided to Civil Protection

Planning for fire control and protection of personnel

International Nuclear Information System (INIS)

Rule, A.V.

1989-01-01

Because nuclear installations are designed and built to high standards with segregation and fire barriers included, the risk from fires is not high. However, small fires can become large and nuclear sites present additional hazards to fire fighters because of radiation release and from metal fires (magnesium alloys and sodium) which require special techniques of firefighting. All sites have their own fire fighting force which would tackle a fire initially and these should train and work in close cooperation with the Local Authority fire service. The main points raised concern radiation protection for the fire fighters including the issuing of emergency dosemeters and potassium iodate tablets, decontamination of personnel, vehicles and equipment, communications, and the need for standardisation of plans at all installations throughout the country.

Fatigue risk management by volunteer fire-fighters: Use of informal strategies to augment formal policy.

Science.gov (United States)

Dawson, Drew; Mayger, Katherine; Thomas, Matthew J W; Thompson, Kirrilly

2015-11-01

An increasing number and intensity of catastrophic fire events in Australia has led to increasing demands on a mainly volunteer fire-fighting workforce. Despite the increasing likelihood of fatigue in the emergency services environment, there is not yet a systematic, unified approach to fatigue management in fire agencies across Australia. Accordingly, the aim of this study was to identify informal strategies used in volunteer fire-fighting and examine how these strategies are transmitted across the workforce. Thirty experienced Australian volunteer fire-fighters were interviewed in August 2010. The study identified informal fatigue-management behaviours at the individual, team and brigade level that have evolved in fire-fighting environments and are regularly implemented. However, their purpose was not explicitly recognized as such. This apparent paradox - that fatigue proofing behaviours exist but that they are not openly understood as such - may well resolve a potential conflict between a culture of indefatigability in the emergency services sector and the frequent need to operate safely while fatigued. However, formal controls require fire-fighters and their organisations to acknowledge and accept their vulnerability. This suggests two important areas in which to improve formal fatigue risk management in the emergency services sector: (1) identifying and formalising tacit or informal fatigue coping strategies as legitimate elements of the fatigue risk management system; and (2) developing culturally appropriate techniques for systematically communicating fatigue levels to self and others.

The forest-fire not only brings great loss to natural resources, but also destructs the ecosystem and reduces the soil fertility, causing some natural disasters as soil erosion and debris flow. However, due to the lack of the prognosis for forest fire spreading trend in forest fire fighting, it is difficult to formulate rational and effective fire-fighting scheme. In the event of forest fire, achieving accurate judgment to the fire behavior would greatly improve the fire-fighting efficiency, and reduce heavy losses caused by fire. Researches on forest fire spread simulation can effectively reduce the loss of disasters. The present study focused on the simulation of "29 May 2012" wildfire in windthrow area of Changbai Mountain. Basic data were retrieved from the "29 May 2012" wildfire and field survey. A self-development forest fire behavior simulated program based on Rothermel Model was used in the simulation. Kappa coefficient and Sørensen index were employed to evaluate the simulation accuracy. The results showed that: The perimeter of simulated burned area was 4.66 km, the area was 56.47 hm2 and the overlapped burned area was 33.68 hm2, and the estimated rate of fire spread was 0.259 m/s. Between the simulated fire and actual fire, the Kappa coefficient was 0.7398 and the Sørensen co-efficient was 0.7419. This proved the application of Rothermel model to conduct fire behavior simulation in windthrow meadow was feasible. It can achieve the goal of forecasting for the spread behavior in windthrow area of Changbai Mountain. Thus, our self-development program based on the Rothermel model can provide a effective forecast of fire spread, which will facilitate the fire suppression work.

This study aims to analyze the potential aplication of of palm oil-based foaming agent as peat fires fighter in Indonesia. From literature review, it has been known that the foaming agent able to form foam to extinguish fire, wrap and refrigerate the burning peat. It is necessary to develop the production and application of foaming agent in Indonesia because peat fires occur almost every year that caused smoke haze. Potential raw material for the production of environmental friendly foaming agent as foam extinguishing for peat fires in Indonesia aong other is palm oil due to abundant availability, sustainable, and foam product easily degraded in the environment of the burnt areas. Production of foaming agent as fire-fighting in Indonesia is one alternative to reduce the time to control the fire and smog disaster impact. Application of palm oil as a raw material for fire-fighting is contribute to increase the value added and the development of palm oil downstream industry.

As a part of Fire PSA for KAPS, a pilot study has been taken up identifying CWPH as the important zone vulnerable to fire. As the CWPH houses pumps belonging to all important cooling (APWC, FFW, NAHPPW, NALPW, etc.) of both the units, a single fire leads to failure of multiple safety/safety support system cooling affecting the safety of the plant. The objective of this study is as follows: Familiarising with the various published Fire-PSA study, comparing and finalisation of the computer code amongst various codes available with DAE, identifying and sequencing different activities involved for carrying out Fire PSA, i.e. Zoning and Sub-Zoning of Fire Source Area, Fire vulnerability of System and Component surrounding Fire Source, etc., finalization of report format and documentation. Computer Code FDS is used to carry out Fire Hazard Analysis. FDS is the latest state-of the-art software package extensively used for Fire Hazard Analysis. It develops a 3D scenario for any given fire giving credit to actual physical location of fire load and ventilation. It gives the time dependent of any fire in a specific zone crediting the time required by operator to take necessary preventive action which helps in quantifying the probability of error for any particular operator's for PSA study. To identify the most vulnerable sub-zone in CWPH, a walk down was organized and physical location of each load; their separation, fire barrier, ventilator in the room, arrangement of fire protection/fighting system, localized operator's room were reviewed. Fire in the middle diesel tank with pump is considered as initiating event in the sub-zone of CWPH. The Event Tree for this initiating event for CWPH was developed. Event Tree end states are identified as large fire i.e. fire which is failed to be detected by both means, i.e. early and late and failure in fighting by both means i.e. early and late. (author)

1995-01-01

The Ministry of Education, Culture and Social Welfare (MOECSW), as part of the Population Education Programs (formal and informal), undertook a series of training programs to upgrade the knowledge and skills of master trainers, supervisors, and resource persons. As part of the Population Education in the Formal School Sector Project (NEP/93/P01), under the Curriculum Development Centre five training courses were organized to train 220 master trainers. Under the "Three Steps Training Strategy," these 220 master trainers would teach 825 secondary school headmasters who would reach 2025 secondary school teachers. The training courses were held in Dhangadi, April 23-27, 1995; in Pokhara, April 2-7; and in Biratnagar, February 20-24. The areas covered included: 1) the pedagogical aspect of population education (content, scope, objectives, nature, teaching methodologies); 2) demography and population dynamics (composition, distribution and density, sources of population data, demographic transition, consequences and determinants of population growth); 3) family life and adolescence and human sexuality education, including acquired immunodeficiency syndrome (AIDS) education; 4) maternal and child health, and family planning; 5) environment; and 6) population policy and programs. As part of the Population Education Programme (NEP/93/P08), a Master Trainers Training Workshop was held in Makwanpur, March 26-28, 1995. These master trainers would train trainers who would train the facilitators and teachers at learning centers for adult learners under the literacy and post literacy programs. This course focused on the approaches and strategies for integrating population education in development programs, and non-formal education, adult literacy, post literacy, and out-of-school children programs. Dr. D. de Rebello and Mr. S. Hutabarat, CST Advisors on Population Education, organized the training courses and served as resource persons.

Performance of a Protected Wireless Sensor Network in a Fire. Analysis of Fire Spread and Data Transmission

Antoine-Santoni, Thierry; Santucci, Jean-François; de Gentili, Emmanuelle; Silvani, Xavier; Morandini, Frederic

2009-01-01

The paper deals with a Wireless Sensor Network (WSN) as a reliable solution for capturing the kinematics of a fire front spreading over a fuel bed. To provide reliable information in fire studies and support fire fighting strategies, a Wireless Sensor Network must be able to perform three sequential actions: 1) sensing thermal data in the open as the gas temperature; 2) detecting a fire i.e., the spatial position of a flame; 3) tracking the fire spread during its spatial and temporal evolution. One of the great challenges in performing fire front tracking with a WSN is to avoid the destruction of motes by the fire. This paper therefore shows the performance of Wireless Sensor Network when the motes are protected with a thermal insulation dedicated to track a fire spreading across vegetative fuels on a field scale. The resulting experimental WSN is then used in series of wildfire experiments performed in the open in vegetation areas ranging in size from 50 to 1,000 m2. PMID:22454563

A mechanized gait trainer for restoration of gait.

Science.gov (United States)

Hesse, S; Uhlenbrock, D

2000-01-01

The newly developed gait trainer allows wheel-chair-bound subjects the repetitive practice of a gait-like movement without overstressing therapists. The device simulates the phases of gait, supports the subjects according to their abilities, and controls the center of mass (CoM) in the vertical and horizontal directions. The patterns of sagittal lower limb joint kinematics and of muscle activation for a normal subject were similar when using the mechanized trainer and when walking on a treadmill. A non-ambulatory hemiparetic subject required little help from one therapist on the gait trainer, while two therapists were required to support treadmill walking. Gait movements on the trainer were highly symmetrical, impact free, and less spastic. The vertical displacement of the CoM was bi-phasic instead of mono-phasic during each gait cycle on the new device. Two cases of non-ambulatory patients, who regained their walking ability after 4 weeks of daily training on the gait trainer, are reported.

2018-01-01

The aim of the study was to compare exercise recommendations, attitudes, and behaviors of personal trainers toward clients of different weight statuses. Fifty-two personal trainers participated in the study. The data collection was organized into two phases. In phase one, trainers read a profile and watched the video displaying an interview of either an obese or an average-weight client. Profiles and video interviews were identical except for weight status. Then, trainers provided exercise recommendations and rated their attitude toward the client. In phase two, trainers personally met an obese or an average-weight mock client. Measures were duration and number of advices provided by the trainer to a question posed by the client and sitting distance between trainer and client. There were no significant differences in exercise intensity ( p = .94), duration of first session ( p = .65), and total exercise duration of first week ( p = .76) prescribed to the obese and average-weight clients. The attitude of the personal trainers toward the obese client were not significantly different from the attitude of personal trainers toward the average-weight client ( p = .58). The number of advices provided ( p = .49), the duration of the answer ( p = .55), and the distance personal trainers sat from the obese client ( p = .68) were not significantly different from the behaviors displayed toward the average-weight client. Personal trainers did not discriminate against obese clients in professional settings.

Fire Source Accessibility of Water Mist Fire Suppression Improvement through Flow Method Control

Recently, nuclear power plants set CO{sub 2} fire suppression system. However it is hard to establish and to maintain and it also has difficulties performing function test. Therefore, it needs to develop a new fire suppression system to replace the existing CO{sub 2} fire suppression systems in nuclear power plant. In fact, already, there exist alternatives - gas fire suppression system or clean fire extinguishing agent, but it is hard to apply because it requires a highly complicated plan. However, water mist fire suppression system which has both water system and gas system uses small amount of water and droplet, so it is excellent at oxygen displacement and more suitable for nuclear power plant because it can avoid second damage caused by fire fighting water. This paper explains about enclosure effect of water mist fire suppression. And it suggests a study direction about water mist fire source approach improvement and enclosure effect improvement, using flow method control of ventilation system. Water mist fire suppression can be influenced by various variable. And flow and direction of ventilation system are important variable. Expectations of the plan for more fire source ventilation system is as in the following. It enhances enclosure effects of water mists, so it improves extinguish performance. Also the same effect as a inert gas injection causes can be achieved. Lastly, it is considered that combustible accessibility of water mists will increase because of descending air currents.

Lamuth, P.; Lernout, L.A.; Bonneval, F.; Cottaz, M.

1996-01-01

In the context of fire protection in technical buildings of French nuclear facilities, three principles have been adopted: prevention, detection and fire-fighting. Their implementation makes it possible on the one hand to limit the fire ignition and the fire growth, and on the other hand to prevent fire extent which would lead to unavailability of several safety related equipment. Although progress has been made in this direction, the fire risks have still not been eliminated. It is therefore essential to evaluate the fire effects and to assess their consequences. To this end, three main R and D programs have been conducted into fires. Part I sets out the fire PSA methodology used for a 900 MWe PWR. Part II gives an outline of two fire and ventilation computer codes useful for the fire PSA. Finally, part III gives an outline of the tests already performed and those currently under way in the two laboratories of the Institut de Protection et de Surete Nucleaire (IPSN) in order to qualify the codes and provide useful information for the safety assessment.

2013-01-01

Fire protection concepts are supposed to be a decision guide for the definition of measures and priorities in fire fighting and fire prevention. In case of reactor dismantling a fire protection concept for the actual status is required. Following the fuel removal from the reactor the protection goals are reduced to the safe confinement of radioactive materials and the restriction of radiation exposure. A dynamic fire protection concept was developed to allow the compliance with the required protection measures with respect to the protection targets. The implementation of the dynamic fire protection concept simplifies the planning of the dismantling steps and to adjust the fire protection measured in the frame of changes in the plant.

Aerial wildfire fighting: history, current situation, problems and perspectives

Directory of Open Access Journals (Sweden)

2017-10-01

Full Text Available Nowadays aviation is among the most effective ways of early detection and suppression of wildfires. At the moment for the aerial wildfire fighting a few dozen models of aircraft are used worldwide, which are regularly modernized and renewed. In this article, authors give information about the history of fighting wildfires from the air, as well as analyze the current state of the issue with the use of aircraft and helicopter airtankers for firefighting, both at international level and in the territory of the Russian Federation. It is revealed that the most popular in the world still are the ground-based firefighting aircraft (regardless of the class of the carrying capacity. Amphibious firefighting aircraft now exist only in light (carrying capacity up to 5 tons and in medium type (capacity up to 15 tons. Among the helicopter aviation, heavy firefighting helicopters are mostly widely spread, as well as medium multipurpose helicopters, which are, apart from suppression, involved into delivery of people and goods to forest fire sites. The article is devoted to the main directions, according to which the development of aircraft tanker equipment abroad and in Russia occurs. The attention is directed to the most promising developments, and specific recommendations on how to increase the effectiveness of the fire aviation usage in Russia are given. Based on the studies carried out, a conclusion is drawn that for different countries there can be promising different types of firefighting aircraft, considering their landing field infrastructure, characteristics of forests and hydro systems, as well as the total area of the forest fund.

The purpose of this workshop will be to provide a bridge between engineering practices, modeling, and measurement of fires and explosions, and use this information in a practical manner to improve the fire safety of the process facility. New techniques and information are available on the means to prevent, predict and mitigate fires and explosions. A review of BLEVEs and methods for preventing and protecting against the effects of BLEVES in large petrochemical facilities. Observations and the use of models that have been successful in predicting the effects of vapor explosions for the prevention of collapse of structures and mitigation of the effects of vapor explosions in process facilities are presented. Recent work involving the measurement of radiation from large jet fires at the Kuwaiti oil fields and fire tests of crude oil spills on the sea is discussed. Fire radiation measurement can be used to predict effects on structures, facilities, and the complexity of fire fighting operations required for control of spill and pool fires. Practical applications of techniques for prevention and control of explosions within building, resulting from failures of autoclaves or release of flammable gas to the atmosphere of the building are discussed.

1976-02-05

Spontaneous combustion ahead of the face occurred in an over-worked and under-worked seam. When the first cavity containing hot ash was found, an attempt to extinguish the fire with water was abandoned because of the quantity of steam produced, but the fire was extinguished by covering it with paste containing magnesium chloride and hydroxide and calcium chloride. Mining operations continued while the coal surrounding the hot region was cooled with water. The steps taken to detect and deal with other fires in advance of the face are described. These included pre-infusion with calcium chloride solution via boreholes and treatment of the hot cavities encountered with magnesium chloride paste. This method of fire-fighting was more successful than the use of water alone.

2017-12-01

Few studies have examined the sources of practice knowledge fitness trainers use to inform their training methods and update knowledge. This study aims to describe sources of practice knowledge among Australian fitness trainers. In July 2014, 9100 Australian fitness trainers were invited to complete an online survey. Respondents reported the frequency of use of eight sources of practice knowledge (e.g. fitness magazines, academic texts). In a separate survey, exercise science experts (n = 27) ranked each source as either (1) 'high-quality' or (2) 'low-quality'. Proportions of users of 'high-quality' sources were calculated across demographic (age, sex) and fitness industry-related characteristics (qualification, setting, role). A multivariate logistic regression analysis assessed the odds of being classified as a user of high-quality sources, adjusting for demographic and fitness industry-related factors. Out of 1185 fitness trainers (response rate = 13.0%), aged 17-72 years, 47.6% (95% CI, 44.7-50.4%) were classified as frequent users of high-quality sources of practice knowledge. In the adjusted analysis, compared to trainers aged 17-26 years, those aged ≥61 years (OR, 2.15; 95% CI, 1.05-4.38) and 40-50 years (OR, 1.54; 95% CI, 1.02-2.31) were more likely to be classified as a user of high-quality sources. When compared to trainers working in large centres, those working in outdoor settings (OR, 1.81; 95% CI, 1.23-2.65) and medium centres (OR, 1.59; 95% CI, 1.12-2.29) were more likely to be classified as users of high-quality sources. Our findings suggest that efforts should be made to improve the quality of knowledge acquisition among Australian fitness trainers.

The mechanics of movement of a liquid in the diffuser of the injector of an automatic extinguishing installation with preaeration of the fire-fighting substance was theoretically investigated. An integral solution of the equation for movement of the preaerated fire-fighting gas-liquid mixture in the indicated diffuser has been obtained. A mathematical model of two-phase liquid flow in this diffuser, which allows one to calculate the distribution of the average pressure in the diffuser along its length and to determine the loss in this pressure, has been developed. This model can be used for designing the output region of a hydraulic system with a hydrodynamic drag providing the operation of its injector in a definite regime.

Kandrac, J.; Lukac, L.

1987-01-01

Fire protection of cable ducts in the Bohunice and Dukovany V-2 nuclear power plants is of a fourtier type. The first level consists in preventive measures incorporated in the power plant design and layout. The second level consists in early detection and a quick repressive action provided by an electric fire alarm system and a stationary spray system, respectively. Fire partitions and glands represent the third level while special spray, paint and lining materials represent the fourth level of the protection. Briefly discussed are the results of an analysis of the stationary spray system and the effects reducing the efficiency of a fire-fighting action using this system. The analysis showed the need of putting off cable duct fires using mobile facilities in case the stationary spray system cannot cope any longer. (Z.M.). 3 figs., 2 refs

A Forest Fire Sensor Web Concept with UAVSAR

Science.gov (United States)

Lou, Y.; Chien, S.; Clark, D.; Doubleday, J.; Muellerschoen, R.; Zheng, Y.

2008-12-01

We developed a forest fire sensor web concept with a UAVSAR-based smart sensor and onboard automated response capability that will allow us to monitor fire progression based on coarse initial information provided by an external source. This autonomous disturbance detection and monitoring system combines the unique capabilities of imaging radar with high throughput onboard processing technology and onboard automated response capability based on specific science algorithms. In this forest fire sensor web scenario, a fire is initially located by MODIS/RapidFire or a ground-based fire observer. This information is transmitted to the UAVSAR onboard automated response system (CASPER). CASPER generates a flight plan to cover the alerted fire area and executes the flight plan. The onboard processor generates the fuel load map from raw radar data, used with wind and elevation information, predicts the likely fire progression. CASPER then autonomously alters the flight plan to track the fire progression, providing this information to the fire fighting team on the ground. We can also relay the precise fire location to other remote sensing assets with autonomous response capability such as Earth Observation-1 (EO-1)'s hyper-spectral imager to acquire the fire data.

Winterstein, A P

1998-01-01

To 1) examine the commitment of head athletic trainers to their intercollegiate work environments, 2) develop a model that better reflects the head athletic trainer's daily work setting, and 3) use new techniques to describe the various ways head athletic trainers demonstrate commitment to their organizations. Organizational commitment (OC) surveys were sent to 461 head athletic trainers identified for the sample. A response rate of 71.5% (330/461) was obtained from the mail survey. A proportional random sample of head athletic trainers was taken from a population identified in the National Association of Collegiate Directors of Athletics (NACDA) directory of intercollegiate athletics as Division I, II, and III institutions. Returned OC surveys were analyzed using descriptive and inferential statistics for all demographic and OC variables. Exploratory cluster analysis was performed to examine naturally clustering groups. Exploratory cluster analysis revealed five naturally clustering groups that represent the head athletic trainers' patterns of commitment across the specific organizational targets. Paired t tests indicated that the continuance commitment scores were significantly lower than the affective and normative scores across the sample. Analysis of variance tests indicated significant differences for specific commitment dimensions based on gender and NCAA division demographics. Beyond that, the five-cluster solution revealed no particular demographic characteristics that predisposed individuals to specific clusters. THE FINDINGS REINFORCE A CENTRAL THEME IN INTERCOLLEGIATE ATHLETIC TRAINING: that student-athletes and student athletic trainers are the primary focus of the head athletic trainers' commitment. Positive attachment and obligation directed toward student-athletes and student athletic trainers link the five clusters. Commitment patterns in areas other than student-athletes and student athletic trainers define the cluster membership or head athletic

After summarising the key findings of the review, it focuses on mental health, briefly exploring the links between mental and physical health before discussing what differences engagement with a health trainer made to people's sense of self-efficacy and wellbeing. Health trainers are a non-clinical workforce introduced in 2004,(2) who receive training in competencies to enable them to support people in disadvantaged communities to improve their health.(3) The population groups or settings that health trainers focus on varies from service to service, but all work one-to-one, most spending at least an hour with a client at their first appointment, supporting and enabling them to decide what they want to do. The emphasis is on the client determining their own priorities and how to achieve them. Generally, health trainers see clients for a total of six sessions, where how to achieve goals and progress towards them is discussed. The Data Collection and Reporting System (DCRS) is used by approximately 60% of Health Trainer Services to record monitoring data. Around 90% of Health Trainer Services using DCRS record ethnographic data on health trainers and clients, plus the issues clients worked on and the progress they made. There is also a wide range of other data which can be recorded, including before and after mental health and wellbeing scores. We were given access to aggregate data in order to conduct an analysis. Descriptive statistics were generated to calculate percentage change pre- to post-intervention. A total of 1,377 (= 919 full time equivalents) health trainers were recorded in the DCRS system as working with 97,248 clients in England during 2013/2014. The health trainer model embodies the principle of lay support,(4) and services aim to recruit a high proportion of their staff from similar

The Reactor Trainer is a professional, PC based, graphically enhanced, training resource specifically developed and customized for Class Room teaching of and learning about, reactor behavior. This unique, and focused, learning-target sets The Trainer apart from the panorama of the more common PC plant simulator. Its educational scope extends along a logical learning path, starting with important fundamental behavioral concepts of delayed neutrons, neutron multiplying factors, and reactor rate, moving to simple reactor transients in real time, and culminating with more complex operational evolutions. The Trainer empowers the Instructor with a dynamic Class Room demonstrator and the student with a superior hands-on learning tool. The Trainer's versatility encompasses a wide variety of educational needs, including initial operator training, requalification training, Shift Technical Advisor training, and other advanced or specialized training. In addition, The Reactor Trainer enhances prerequisite preparation of operator candidates for full-scale control room training and, in so doing, PC economics relieves full-scale simulator hours.

To investigate whether a virtual reality simulator (LapSim) and traditional box trainer are effective tools for the acquisition of basic laparoscopic skills, and whether the LapSim is superior to the box trainer in surgical education. In a study at Ege University School of Medicine, Izmir, Turkey, between September 2008 and March 2013, 40 first- and second-year residents were randomized to train via the LapSim or box trainer for 4 weeks, and 20 senior residents were allocated to a control group. All 3 groups performed laparoscopic bilateral tubal ligation. Video records of each operation were assessed via the general rating scale of the Objective Structured Assessment of Laparoscopic Salpingectomy and by operation time in seconds. Compared with the control group, the LapSim and box trainer groups performed significantly better in total score (Peducation. Training with a virtual reality simulator or box trainer should be considered before actual laparoscopic procedures are carried out.

A virtual trainer concept for robot-assisted human motor learning in rowing

Directory of Open Access Journals (Sweden)

Baumgartner L.

2011-12-01

Full Text Available Keeping the attention level and observing multiple physiological and biomechanical variables at the same time at high precision is very challenging for human trainers. Concurrent augmented feedback, which is suggested to enhance motor learning in complex motor tasks, can also hardly be provided by a human trainer. Thus, in this paper, a concept for a virtual trainer is presented that may overcome the limits of a human trainer. The intended virtual trainer will be implemented in a CAVE providing auditory, visual and haptic cues. As a first application, the virtual trainer will be used in a realistic scenario for sweep rowing. To provide individual feedback to each rower, the virtual trainer quantifies errors and provides concurrent auditory, visual, and haptic feedback. The concurrent feedback will be adapted according to the actual performance, individual maximal rowing velocity, and the athlete’s individual perception.

Fire safety in nuclear power stations

International Nuclear Information System (INIS)

Kench, R.L.

1988-01-01

This is the first of a three-part report on the fire hazards in nuclear power stations and some of the precautions necessary. This part lists the United Kingdom reactors, outlines how they work, the fuels used, the use of moderators and coolants and the control systems. Although the risk of fire is no higher than in fossil-fuel stations the consequences can be more serious. The radioactive materials used mean that there is biological shielding round the core, limitations on waste emissions allowed and limited access to some zones. Reliable shut-down systems are needed. Care in the use of water to fight fires must be exercised -it can act as a moderator and cause an otherwise safe core to go critical. The Wigner effect in graphite moderated reactors is explained. Fires in graphite can be extinguished by carbon dioxide. Argon, chlorine and sodium silicate can also be effective. In sodium cooled reactors fires can be allowed to burn themselves out, or TEC and argon could be used to extinguish the flame. (UK)

The safety goal for nuclear installations is to prevent the dispersal of radioactive substances, both in the work area and outside the buildings into the environment. It is therefore at the design stage, then during construction and subsequent operation that it is necessary to take preventive measures against the outbreak of fire, and to take precautions to ensure that the consequences will always be limited. The paper describes the arrangements made by the French safety authorities to provide protection against fire in both nuclear plants and nuclear fuel cycle installations at all these stages

Fighting forest fires not only depends on the forest type, topography, and weather conditions, but is also closely related to the technical properties of fire-fighting equipment. Firefighting is an important part of fire management planning. However, because of the complex nature of forests, creating thematic layers to generate potential fire risk maps is difficult. The use of remote sensing data has become an efficient method for the discrete classification of potential fire risks. The study was located in the Central District of the Kastamonu Regional Forest Directorate, covering an area of 24,320 ha, 15,685 ha of which is forested. On the basis of stand age, crown closure, and tree species, the sizes and distributions of potential fire risk zones within the study area were determined using high-resolution GeoEye satellite imagery and geographical information system data. The status of pumper truck intervention in zones with high fire risk and the sufficiency of existing forest roads within an existing forest network were discussed based on combustible matter characteristics. Pumper truck intervention was 83% for high-risk zones, 79% for medium-risk zones, and 78% for low-risk zones. A pumper truck intervention area map along existing roads was also created.

Foam for combating mine fires

Energy Technology Data Exchange (ETDEWEB)

1989-09-01

The application of foam in dealing with underground fire is well known due to its smothering action by cutting off air feed to burning fuel as well as acting as coolant. Besides plugging air feed to fire, water could be virtually reached to the fire affected areas much beyond the jet range as underground galleries with low roof restrict jet range of water. This method also enables a closer approach of a fire fighting team by isolating the toxic gases and smoke with a foam plug. The paper describes the development of high expansion foam composition and its application technology in order that foam plug method can be suitably utilized for combating mine fires in India. Three compositions were recommended for generation of high expansion foam: (a) 0.5% sodium/ammonium lauryl sulphate, 0.15 to 0.2% sodium carboxy methyl cellulose, 0.1% booster; (b) 0.5% sodium/ammonium lauryl sulfate, 0.12 to 0.15% alkaline solution of gum arabic, 0.1 to 0.2% ferrous gluconate; and (c) 0.35% sodium/ammonium lauryl sulfate, 0.20% booster, 0.2% xylene sulfonate.

Pediatric emergency medicine (PEM) physicians have minimal experience in life saving procedures and have turned to task trainers to learn these skills. Realism of these models is an important consideration that has received little study. PEM physicians and trainees participated in a day long procedural training course that utilized commercially available and homemade task trainers to teach pericardiocentesis, chest tube insertion, cricothyroidotomy and central line insertion. Participants rated the realism of the task trainers as part of a post-course survey. The homemade task trainers received variable realism ratings, with 91% of participants rating the pork rib chest tube model as realistic, 82% rating the gelatin pericardiocentesis mold as realistic and 36% rating the ventilator tubing cricothyroidotomy model as realistic. Commercial trainers also received variable ratings, with 45% rating the chest drain and pericardiocentesis simulator as realistic, 74% rating the crichotracheotomy trainer as realistic and 80% rating the central line insertion trainer as realistic. Task training models utilized in our course received variable realism ratings. When deciding what type of task trainer to use future courses should carefully consider the desired aspect of realism, and how it aligns with the procedural skill, balanced with cost considerations.

2011-01-01

With the occurrence of a fire at Kashiwazaki Kariwa No. 3 unit on a site transformer when Niigata Chuetsu Offshore Earthquake occurred in 2007, the movement of establishing station fire brigade broke out all over Japan. Fire brigade of U.S. power stations is an organization structured with the standards of clear requirements. Some of station fire event reports include examples of activation of station fire brigade. Preparing station fire brigade with good expertise is quite meaningful on the viewpoint of ruling out significant threats of fire against nuclear safety, such as Browns Ferry station fire occurred in 1975. The purpose of this study is to extract useful knowledge through making research on examples of operations of station fire brigade of both Japan and the U.S. As for fire occurrence, relatively frequent fires are seen at Japanese stations with miscellaneous components or some material for works. In the U.S., on the other hand, we can identify relatively frequent fires occurred with important equipment. This might make fire brigades of the U.S. well-prepared for fire fighting by establishing fire-coping strategies for every location in the station. Also, in some stations, fire brigade is continuously trained to enhance its firefighting and rescuing abilities. With the aspect of training of brigades, they are often assembled with devoted staff, which enable them acquiring frequent training and educations to improve their skills further. Fire fighting and rescuing are inevitably dangerous task. This is why frequent training is essential in order to prevent injuries and to keep up their motivation. Unfortunately, the circumstance for brigades in Japan is not helpful enough in experiencing special training needed for them. We have to figure out some way to get over such disadvantages. (author)

Developing programs and actions to fight stigma and discrimination against people living with mental disorders is a priority both internationally and in France. Involving mental health service users in these anti-stigma programs has proved to be a key element for effective programs. The present study evaluates the impact of user-trainers in an anti-stigma campaign with job counselors on their knowledge, beliefs, and desire for social distance with regard to mental illness and the mentally ill. Eighty-nine professionals participated in eight mental health awareness days from December 2008 to June 2009. Each training day was built around two pedagogical units: firstly, a psychiatrist providing a theoretical overview of mental illness and care and secondly, user-trainers describing their point of view on mental illness and exchanging with participants. A questionnaire administered at the beginning and at the end of the mental health awareness day assessed the impact of the day on participants' knowledge, beliefs, and desire for social distance. Answers to open questions were evaluated using thematic qualitative analysis. The intervention had statistically significant positive effects on all three training objectives: knowledge, beliefs and desire for social distance. Analysis of qualitative data confirmed participants' need for information and training with regard to providing support to clients with mental health problems; participants frequently attributed their improved self-confidence at the end of the day with regard to providing job coaching for this population group to the presence of user-trainers. A mental health awareness day using mental health service users and psychiatrists as trainers had significant positive effects in terms of reducing stigma with regard to people with mental illness. Further research is needed to understand whether the impact of such awareness approaches can be maintained in everyday professional practice over time. Copyright © 2013

A passenger compartment surrounded by a fire-retardant shell, to protect the occupants long enough for the fire to burn out or for fire-fighting equipment to reach the aircraft and extinguish it, is proposed as a new concept for saving lives in crash fires. This concept is made possible by the recent development of two new fire-retardant materials: a very lightweight foam plastic, called polyisocyanurate foam, and an intumescent paint. Exposed to heat, the intumescent paint expands to many times its original thickness and insulates the surface underneath it. Demonstration tests are illustrated, described and discussed. However, some problems, such as preventing fuselage rupture and protecting windows, must be solved before such a system can be used.

The Royal College of General Practitioners in partnership with the South African Academy of Family Physicians obtained funding to run a series of 'Training the Trainers' courses for trainers of family medicine registrars, with a view to strengthening clinical supervision of postgraduate registrars. The authors wanted to establish whether it was worthwhile for the course to be provided on an ongoing basis after the funded project was completed. Development of a pilot tool for evaluation visits after a faculty development course. The authors developed a pre-visit pack and conducted five site visits to registrar trainers who had been on the course between 12 and 24 months earlier. Before the series of visits and after each visit we debriefed and modified our approach. Optimising the use of the pre-visit pack will require greater orientation of the trainer. Administrative support for the visits will be vital. The visits were experienced very positively. However, in a context in which these visits are not the norm, the trainers need support and encouragement to participate in an activity which made them feel quite vulnerable. The tool enabled course participants to show evidence of their behaviour change, enabled their colleagues to report on the impact on their own teaching practices, and enabled registrars to voice their opinions of their trainer's supervision skills. A post-course formative evaluation visit has the potential to catalyse the impact of the training course. It will be necessary to train the family physicians who conduct these visits.

We developed the iTrainer (iT) as a portable laparoscopic trainer, which incorporates the iPad tablet. We then compared the iT with a standard pelvic trainer (SPT) to assess surgical skills as well as its image quality, resolution, brightness, comfort, and overall performance. We designed and constructed the iT to be compatible with the Apple iPad 3 and standard laparoscopic instruments. Participants were assigned to perform the thread-the-loops task on both trainers and were prospectively randomized to start on either the iT or the SPT. Each participant was allowed a 2-minute warm-up before the 2-minute testing period. We scored participants using the product of skill quality (0-4 scale) and quantity of loops threaded (0-10 scale). Participants then rated each trainer on image quality, resolution, brightness, comfort, and overall performance on a 5-point Likert scale. A total of 45 subjects including 10 undergraduates, 10 medical students, 10 general surgery and urology residents, and 15 experts (fellows and attending surgeons) participated in this study. There was no significant difference between thread-the-loops task scores completed on the iT when compared with the SPT for all groups tested (p > 0.05) with the exception of the medical student group, who performed better on the SPT (p < 0.05). On evaluation of each trainer, participants rated the iT as having superior image quality and resolution when compared with the SPT (p < 0.05) but rated the SPT higher in overall performance (p < 0.05). Brightness and comfort were rated similarly for both trainers. We have demonstrated face validity and criterion validity for the thread-the-loops task on the iT. The iT rated superior in image quality and resolution but inferior in overall performance compared with the SPT. The iT provides trainees a unique advantage over SPT as an additional resource to laparoscopic training as it is inexpensive, portable, and can be readily available for training. Copyright © 2014

Addressing inequalities in health--what is the contribution of health trainers?

The role that members of the public (non-professional lay people) can play in improving health is being increasingly recognised in research and policy. This paper explores what contribution lay people employed as health trainers are making to addressing health inequalities in England. Data from eight local evaluations of health trainer services were synthesised using a data-extraction framework to find out about client populations, any lifestyle changes made, health trainers' background and community engagement activities. These data were compared with national data to assess how findings relating to addressing inequalities compared with the national picture. Local data largely matched national data and showed that health trainers are reaching people living with disadvantage and enabling them to make lifestyle changes. The data suggest that they do this by engaging with communities and taking a person-centred approach. Being non-clinical peers is also important. However, no evidence was found that health trainers were impacting on health inequalities at a population level. Health trainers are contributing to addressing health inequalities but the services evaluated were small and had been operating for a limited time, so to expect reductions in inequalities at a population level within districts would be unrealistic. The findings of this synthesis present a challenge to primary care and public health to employ health trainers in order to engage marginalised communities as one element of plans to address health inequalities.

To assess the efficacy of a novel high-fidelity epistaxis simulator in teaching epistaxis management to junior otolaryngology head and neck surgery residents. Prospective cohort study. A novel high-fidelity epistaxis task trainer was developed using a cadaver head, intravenous tubing, and a food coloring-filled saline bag to emulate blood. Learners were instructed on two techniques of nasal packing (formal nasal pack and nasal tampon) for the management of epistaxis using the task trainer. Learners were videotaped attempting to pack the nose of the task trainer pre- and postintervention (verbal instruction, and practice time with task trainer). Five board-certified otolaryngologists (blinded to pre- and postintervention status) evaluated the packing technique using standardized subjective outcome measures. There were 13 junior otolaryngology residents enrolled in the study. This cohort showed a statistically significant increase in global rating scores (P epistaxis simulator has been successful in teaching and the practical application of various skills in epistaxis management. This task trainer appears to confer an educational benefit in technical skills acquisition in novice learners. Further studies are needed to determine long-term skill retention.

Full Text Available The aim of this small-scale research is to explore the hidden world of the workplace trainer. Four trainers from a training institute in Qatar were interviewed and asked about their opinions of the employee as a learner, the trainer’s work, and the role of quality compliance in the training process. After transcribing and analysing the semi- structured interviews, several themes concerning the employee as a learner emerged such as the employees’ motivation and the effects of the workplace environment on learning. The findings also showed the trainers’ need for an adequate professional development plan and a reconsideration of their power inside the classroom. Regarding the quality compliance, there were various insights and suggestions for improvement. The results of this study are important to any workplace trainers, human development, and quality compliance employees or anyone interested in knowing more about the world of adult learning.

Given the heritability of human left-handedness and its purported associations with fitness-lowering traits, the persistence of the minority of left-handedness in human populations is an evolutionary puzzle. The fighting hypothesis proposes that these negative fitness costs are offset by fitness gains for left-handers when involved in fights with right-handers, as being a minority would generate a surprise effect increasing the chance of winning. The finding that left-handers are overrepresen...

The French fire protection concept. Vulnerability analysis

International Nuclear Information System (INIS)

Kaercher, M.

1998-01-01

The French fire protection concept is based on a principle of three levels of defence in depth: fire prevention, fire containing and fire controlling. Fire prevention is based on arrangements which prevent the fire from starting or which make difficult for the fire to start. Fire containing is based on design measures so that the fire will have no impact on the safety of the installation. For fire controlling, equipment nad personnel are on duty in order to detect, to fight and to gain control over the fire as early as possible. The French fire protection concept gives priority to fire containing based on passive structural measures. All buildings containing safety equipment are divided into fire compartments (or fire areas) and fire cells (or fire zones). Basically, a compartment houses safety equipment belonging to one division (or train) so that the other division is always available to reach the plant safe shut down or to mitigate an accident. Because there is a large number of fire compartments and fire cells, deviations from the general principle can be observed. To this reason the RCC-I (Design and Construction Rules applicable for fire protection) requires to implement an assessment of the principle of division. This assessment is called vulnerability analysis. The vulnerability analysis is usually performed at the end of the project, before erection. It is also possible to perform a vulnerability analysis in an operating nuclear power plant in the scope of a fire safety upgrading programme. In the vulnerability analysis, the functional failure of all the equipment (except for those protected by a qualified fire barrier, designed or able to withstand the fire consequences) within the fire compartment or cell, where the fire breaks out, is postulated. The potential consequences for the plant safety are analysed

2010-01-01

Simulation-based training in medical education is increasing. Realism is an integral element of creating an engaging, effective training environment. Although physical trainers offer a low-cost alternative to expensive virtual reality (VR) simulators, many lack in realism. The aim of this research was to enhance the realism of a laparoscopic box trainer by using a simple, inexpensive method. Digital images of the abdominal cavity were captured from a VR simulator. The images were printed onto a laminated card that lined the bottom and sides of the box-trainer cavity. The standard black neoprene material that encloses the abdominal cavity was replaced with a skin-colored silicon model. The realism of the modified box trainer was assessed by surgeons, using quantitative and qualitative methodologies. Results suggest that the modified box trainer was more realistic than a standard box trainer alone. Incorporating this technique in the training of laparoscopic skills is an inexpensive means of emulating surgical reality that may enhance the engagement of the learner in simulation.

Probabilistic approach relative to fire scenarios study

International Nuclear Information System (INIS)

Chabot, Jean-Luc

1998-01-01

The main objective of this thesis is to develop a calculation method of the occurring probability of the fire scenarios (detection, setting of the intervention, extinction) taking into account the size and the impact of the fire on the surroundings. This new method is called 'hybrid simulation'. It includes in a unique modelling the processing of continuous and discrete phenomenon. Moreover, to correctly represent fire scenarios, it is necessary not to take only into account the 'continuous' growing of the fire itself but of also 'discrete' events like detection, fire fighting and extinction, human behaviour and related faults. For that purpose we couple a code modelling the physical aspects of the fire to Petri nets which is able to model these 'discrete' events, this coupling consists of driving the 'continuous' model by the occurring of the 'discrete' events. This new technique which can be used to cover 'discrete' and 'continuous' events in a single calculation represents a solution to dynamic reliability calculation problems, for which there is a continuously increasing demand for analysing reliability, availability of production and maintainability of complex industrial systems.

2014-04-01

Full Text Available In this paper we introduce a new generation of language trainers: intelligent virtual agents (IVAs with human appearance and the capability to teach foreign language vocabulary. We report results from studies that we have conducted with Billie, an IVA employed as a vocabulary trainer, as well as research findings on the acceptance of the agent as a trainer by adults and children. The results show that Billie can train humans as well as a human teacher can and that both adults and children accept the IVA as a trainer. The advantages of IVAs are multiple. First, their teaching methods can be based on neuropsychological research findings concerning memory and learning practice. Second, virtual teachers can provide individualized training. Third, they coach users during training, are always supportive, and motivate learners to train. Fourth, agents will reside in the user’s mobile devices and thus be at the user’s disposal everywhere and anytime. Agents in apps will make foreign language training accessible to anybody at low cost. This will enable people around the world, including physically, financially and geographically disadvantaged persons, to learn a foreign language and help to facilitate multilingualism.

Fire Risk Analysis and Optimization of Fire Prevention Management for Green Building Design and High Rise Buildings: Hong Kong Experience

Directory of Open Access Journals (Sweden)

Yau Albert

2014-12-01

Full Text Available There are many iconic high rise buildings in Hong Kong, for example, International Commercial Centre, International Financial Centre, etc. Fire safety issue in high rise buildings has been raised by local fire professionals in terms of occupant evacuation, means of fire-fighting by fire fighters, sprinkler systems to automatically put off fires in buildings, etc. Fire risk becomes an important issue in building fire safety because it relates to life safety of building occupants where they live and work in high rise buildings in Hong Kong. The aim of this research is to identify the fire risk for different types of high rise buildings in Hong Kong and to optimise the fire prevention management for those high rise buildings with higher level of fire risk and to validate the model and also to carry out the study of the conflict between the current fire safety building code and the current trend of green building design. Survey via the 7-point scale questionnaire was conducted through 50 participants and their responses were received and analysed via the statistical tool SPSS software computer program. A number of statistical methods of testing for significantly difference in samples were adopted to carry out the analysis of the data received. When the statistical analysis was completed, the results of the data analysis were validated by two Fire Safety Experts in this area of specialisation and also by quantitative fire risk analysis.

Smouldering Fires in the Earth System

Science.gov (United States)

Rein, G.

2012-04-01

Smouldering fires, the slow, low-temperature, flameless burning, represent the most persistent type of combustion phenomena and the longest continuously fires on Earth system. Indeed, smouldering mega-fires of peatlands occur with some frequency during the dry session in, for example, Indonesia, Canada, Russia, UK and USA. Smouldering fires propagate slowly through organic layers of the ground and can reach depth >5 m if large cracks, natural piping or channel systems exist. It threatens to release sequestered carbon deep into the soil. Once ignited, they are particularly difficult to extinguish despite extensive rains, weather changes or fire-fighting attempts, and can persist for long periods of time (months, years) spreading deep and over extensive areas. Recent figures at the global scale estimate that average annual greenhouse gas emissions from smouldering fires are equivalent to 15% of man-made emissions. These fires are difficult or impossible to detect with current remote sensing methods because the chemistry is significantly different, their thermal radiation signature is much smaller, and the plume is much less buoyant. These wildfires burn fossil fuels and thus are a carbon-positive fire phenomena. This creates feedbacks in the climate system because soil moisture deficit and self-heating are enchanted under warmer climate scenarios and lead to more frequent fires. Warmer temperatures at high latitudes are resulting in more frequent Artic fires. Unprecedented permafrost thaw is leaving large soil carbon pools exposed to smouldering fires for the fist time since millennia. Although interactions between flaming fires and the Earth system have been a central focus, smouldering fires are as important but have received very little attention. DBut differences with flaming fires are important. This paper reviews the current knowledge on smouldering fires in the Earth system regarding combustion dynamics, damage to the soil, emissions, remote sensing and

Fire test of DOT 7A Boxes

International Nuclear Information System (INIS)

Jensen, J.D.

1979-05-01

The primary objective of conducting the full-scale fire tests of the DOT (Department of Transportation) 7A FRP Boxes was to provide information to assist in quantifying the fire hazard of the storage located at the Radioactive Waste Management Complex (RWMC), and to learn if changing the storage array will decrease the fire risk. Also, the level of fire fighting and fire protection required to maintain the risk at the RWMC within acceptable DOE guidelines was investigated. Two full-scale fire tests were conducted at Southwest Research Institute (SwRI) in June 1978, using the DOE 7A FRP Plywood Storage Containers. The fire tests showed that when subjected to a substantial ignition source, the boxes will propagate fire as long as no fire-suppression measures are taken. Fire will breach the boxes and spread the radioactive contaminated waste if it is not extinguished. As the fire progresses, additional boxes will become involved, and eventually the entire storage array will ignite. It is recommended that the use of DOT 7A Boxes be discontinued and replaced with noncombustible storage containers. In the event this is not practicable, guidance recommendations are presented to minimize the large fire loss potential. It is also recommended that an investigation be conducted into the number of boxes that can be destroyed and still maintain a safe environment for employees and the public. This investigation should include how far radioactive contamination will spread, what cleanup will be required, anticipated exposure of the people within the area, and the public impact of such a fire

2014-03-01

Full Text Available Fire is a subject that is always neglected and ignored as far as heritage buildings are concerned. Unlike newly-built buildings, which are required under UBBL to undergo certain fire protection system tests, people are less likely to carry out such tests and detailed assessments for heritage buildings. Thus, this research is significant as it is aimed at accomplishing several objectives including studying the current fire emergency plan, besides identifying and assessing the possible fire hazards in heritage buildings in Penang. Several case studies were carried out at a few premises such as the Khoo Kongsi, Cheah Kongsi, Hock Teik Chen Shin Temple and the Teochew Temple with the aid of the Fire Rescue Department Malaysia (FRDM. The results obtained from this study will be discussed according to several aspects focusing on general health and safety management at the site, the fire-fighting system, fire exit routes and signage at the temples, fire hazards, and fire detection and alarm.

2015-11-01

The Sustainable Trainer Engagement Program (STEP) is a modified train-the-trainer professional development program being conducted by the Lunar and Planetary Institute (LPI). STEP has provided two cohorts of 6-8th grade science specialists and lead teachers in the Houston region with in-depth Earth and Space Science (ESS) content, activities, and pedagogy over 15 days each, aligned with Texas science standards. This project has two over-arching goals: to improve middle school ESS instruction, and to create and test an innovative model for Train-the-Trainer.This poster will share details regarding STEP’s activities and resources, program achievements, and its main findings to date. STEP is being evaluated by external evaluators at the Research Institute of Texas, part of the Harris County Department of Education. External evaluation shows an increase after one year in STEP participants’ knowledge (cohort 1 showed a 10% increase; cohort 2 showed a 20% increase), confidence in teaching Earth and Space Science effectively (cohort 1 demonstrated a 10% increase; cohort 2 showed a 20% increase), and confidence in preparing other teachers (cohort 1 demonstrated a 12% increase; cohort 2 showed a 20% increase). By September 2015, STEP participants led (or assisted in leading) approximately 40 workshops for about 1800 science teachers in Texas. Surveys of teachers attending professional development conducted by STEP participants show very positive responses, with averages for conference workshop evaluations ranging from 3.6 on a 4 point scale, and other evaluations averaging from 4.1 to 5.0 on a 5 point scale.Main lessons for the team on the train-the-trainer model include: a lack of confidence by leaders in K-12 science education in presenting ESS professional development, difficulties in arranging for school or district content-specific professional development, the minimal duration of most school and district professional development sessions, and uncertainties in

Methods for Prediction of Temperature Distribution in Flashover Caused by Backdraft Fire

Directory of Open Access Journals (Sweden)

Guowei Zhang

2014-01-01

Full Text Available Accurately predicting temperature distribution in flashover fire is a key issue for evacuation and fire-fighting. Now many good flashover fire experiments have be conducted, but most of these experiments are proceeded in enclosure with fixed openings; researches on fire development and temperature distribution in flashover caused by backdraft fire did not receive enough attention. In order to study flashover phenomenon caused by backdraft fire, a full-scale fire experiment was conducted in one abandoned office building. Process of fire development and temperature distribution in room and corridor were separately recorded during the experiment. The experiment shows that fire development in enclosure is closely affected by the room ventilation. Unlike existing temperature curves which have only one temperature peak, temperature in flashover caused by backdraft may have more than one peak value and that there is a linear relationship between maximum peak temperature and distance away from fire compartment. Based on BFD curve and experimental data, mathematical models are proposed to predict temperature curve in flashover fire caused by backdraft at last. These conclusions and experiment data obtained in this paper could provide valuable reference to fire simulation, hazard assessment, and fire protection design.

Relationship between number and intensity of fighting: evidence from cow fighting tournaments in Valdostana cattle

Directory of Open Access Journals (Sweden)

Cristina Sartori

2014-10-01

Full Text Available Cattle establish firm dominance relationships through ritualised fights. This study aimed at investigating behaviours involved in dominance relationships and effect of factors such as weight, age and repeated fighting experience in fighting dynamics. Subject of the study was the Valdostana breed, whose cows assess dominance relationships in traditional competitions. Tournaments consist in rounds in which cows interact in pairs to assess dominance. Only winners participate in subsequent rounds. An amount of 120 fights involving 145 cows was retained, and winners (51 cows were considered as focal individuals. An ethogram of agonistic interactions was established, including behaviours of different agonistic intensity as physical interactions (pushes, clashes, displays (threats, vocalisations, and non agonistic approaches. A transition diagram of behaviours showed a tendency to express firstly non agonistic approaches and lastly more aggressive clashes. A mixed linear model analysis on traits like competition intensity, duration, and type of behaviours expressed showed a significant effect of age difference on behaviours. However, the most important factor was the number of rounds performed: from the first to subsequent fights agonistic intensity and physical contacts increased, and displays reduced. This may be due either to the fact that more aggressive individuals were likely to be the winners, or that in higher rounds the opponents were more similar regarding fighting ability or aggressiveness and thus more intense fights occurred. The increased aggressiveness after repeated situations of competition suggests suggests that careful attention should be paid to welfare when animals are exposed to situations of high competition, like regrouping.

Adaptive hybrid brain-computer interaction: ask a trainer for assistance!

Science.gov (United States)

Müller-Putz, Gernot R; Steyrl, David; Faller, Josef

2014-01-01

In applying mental imagery brain-computer interfaces (BCIs) to end users, training is a key part for novice users to get control. In general learning situations, it is an established concept that a trainer assists a trainee to improve his/her aptitude in certain skills. In this work, we want to evaluate whether we can apply this concept in the context of event-related desynchronization (ERD) based, adaptive, hybrid BCIs. Hence, in a first session we merged the features of a high aptitude BCI user, a trainer, and a novice user, the trainee, in a closed-loop BCI feedback task and automatically adapted the classifier over time. In a second session the trainees operated the system unassisted. Twelve healthy participants ran through this protocol. Along with the trainer, the trainees achieved a very high overall peak accuracy of 95.3 %. In the second session, where users operated the BCI unassisted, they still achieved a high overall peak accuracy of 83.6%. Ten of twelve first time BCI users successfully achieved significantly better than chance accuracy. Concluding, we can say that this trainer-trainee approach is very promising. Future research should investigate, whether this approach is superior to conventional training approaches. This trainer-trainee concept could have potential for future application of BCIs to end users.

Real-time photorealistic stereoscopic rendering of fire

Rose, Benjamin M.; McAllister, David F.

2007-02-01

We propose a method for real-time photorealistic stereo rendering of the natural phenomenon of fire. Applications include the use of virtual reality in fire fighting, military training, and entertainment. Rendering fire in real-time presents a challenge because of the transparency and non-static fluid-like behavior of fire. It is well known that, in general, methods that are effective for monoscopic rendering are not necessarily easily extended to stereo rendering because monoscopic methods often do not provide the depth information necessary to produce the parallax required for binocular disparity in stereoscopic rendering. We investigate the existing techniques used for monoscopic rendering of fire and discuss their suitability for extension to real-time stereo rendering. Methods include the use of precomputed textures, dynamic generation of textures, and rendering models resulting from the approximation of solutions of fluid dynamics equations through the use of ray-tracing algorithms. We have found that in order to attain real-time frame rates, our method based on billboarding is effective. Slicing is used to simulate depth. Texture mapping or 2D images are mapped onto polygons and alpha blending is used to treat transparency. We can use video recordings or prerendered high-quality images of fire as textures to attain photorealistic stereo.

The goal of the study is to give an overview of the whole diversified research field of fire technology and its problems. For this reason the research subjects have been grouped so that the responsibilities of different authorities, the legislation and specifications, various fields of technology, areas of industry, and groups of products could all be found as clearly as possible. The field has been divided into nine sub-areas. They are: general grounds, fire physics and chemistry, structural fire prevention, textiles and furnishings, devices for heating and other use, detection, fire fighting and rescue, quality control, and special problems. The sub-areas have been divided into 34 main subjects and these, excluding those of special problems, further into as many as 117 subject groups. Characteristics and problems of the sub-areas and the main subjects have been described. The subject groups have been characterized by key words and concepts which outline the projects. No concrete research projects and programs have, however, been directly suggested because their extent and contents depend essentially on financing and other available resources.

Application of Paste Backfill in Underground Coal Fires

2009-04-01

Coal fires are known from different coalfields worldwide. China, India, USA, Australia, Indonesia and South Africa are the main countries affected by coal fires. The fires is thermally intensive and cause numerous sinkholes, large-scale subsidence, air pollution, global warming, loss of mining productivity and increasing safety risk. The Wuda Inner Mongolia coalfield has been selected as a possible test area for paste backfill. The traditional methods, executed by fire fighting teams, by covering the coalfire areas with soil, blasting burning coal outcrops and injecting water in the subsurface fire pockets are continuously improved and extended. Initiatives to introduce modern techniques, such as backfill placement at fracture and borehole, to cool down the burning coal and cut off the air supply. This study is to investigate backfill materials and techniques suited for underground coal fires. Laboratory tests were carried out on physical, chemical and mechanical properties of different backfill materials and mixtures thereof. Special attention was paid to materials generated as by-products and other cheaply available materials e.g. fly ash from power plants. There is a good chance that one of the different material mixtures investigated can be used as a technically and economically viable backfill for underground coal fires.

Simulation based procedural training is an effective and frequently used method for teaching vascular access techniques which often require commercial trainers. These can be prohibitively expensive, which allows for homemade trainers made of gelatin to be a more cost-effective and attractive option. Previously described trainers are often rectangular with a flat surface that is dissimilar to human anatomy. We describe a novel method to create a more anatomically realistic trainer using ballistic gelatin, household items, and supplies commonly found in an emergency department such as the plaster wrap typically used to make splints.

Effects of fire on fish populations: Landscape perspectives on persistance of native fishes and nonnative fish invasions

Science.gov (United States)

Dunham, J.B.; Young, M.; Gresswell, Robert E.; Rieman, B.

2003-01-01

Our limited understanding of the short and long-term effects of fire on fish contributes to considerable uncertainty in assessments of the risks and benefits of fire management alternatives. A primary concern among the many potential effects of fire is the effects of fire and fire management on persistence of native fish populations. Limited evidence suggests vulnerability of fish to fire is contingent upon the quality of affected habitats, the amount and distribution of habitat (habitat fragmentation), and habitat specificity of the species in question. Species with narrow habitat requirements in highly degraded and fragmented systems are likely to be most vulnerable to fire and fire-related disturbance. In addition to effects of fire on native fish, there are growing concerns about the effects of fire on nonnative fish invasions. The role of fire in facilitating invasions by nonnative fishes is unknown, but experience with other species suggests some forms of disturbance associated with fire may facilitate invasion. Management efforts to promote persistence of fishes in fire-prone landscapes can take the form of four basic alternatives: (1) pre-fire management; (2) post-fire management; (3) managing fire itself (e.g. fire fighting); and (4) monitoring and adaptive management. Among these alternatives, pre-fire management is likely to be most effective. Effective pre-fire management activities will address factors that may render fish populations more vulnerable to the effects of fire (e.g. habitat degradation, fragmentation, and nonnative species). Post-fire management is also potentially important, but suffers from being a reactive approach that may not address threats in time to avert them. Managing fire itself can be important in some contexts, but negative consequences for fish populations are possible (e.g. toxicity of fire fighting chemicals to fish). Monitoring and adaptive management can provide important new information for evaluating alternatives, but

German data for risk based fire safety assessment

International Nuclear Information System (INIS)

Roewekamp, M.; Berg, H.P.

1998-01-01

Different types of data are necessary to perform risk based fire safety assessments and, in particular, to quantify the fire event tree considering the plant specific conditions. Data on fire barriers, fire detection and extinguishing, including also data on secondary effects of a fire, have to be used for quantifying the potential hazard and damage states. The existing German database on fires in nuclear power plants (NPPs) is very small. Therefore, in general generic data, mainly from US databases, are used for risk based safety assessments. Due to several differences in the plant design and conditions generic data can only be used as conservative assumptions. World-wide existing generic data on personnel failures in case of fire fighting have only to be adapted to the plant specific conditions inside the NPP to be investigated. In contrary, unavailabilities of fire barrier elements may differ strongly depending on different standards, testing requirements, etc. In addition, the operational behaviour of active fire protection equipment may vary depending on type and manufacturer. The necessity for more detailed and for additional plant specific data was the main reason for generating updated German data on the operational behaviour of active fire protection equipment/features in NPPs to support risk based fire safety analyses being recommended to be carried out as an additional tool to deterministic fire hazard analyses in the frame of safety reviews. The results of these investigations revealed a broader and more realistic database for technical reliability of active fire protection means, but improvements as well as collection of further data are still necessary.

2017-07-01

Walking function post-stroke is characterized by asymmetries in gait cycle parameters and joint kinematics. The Re-Link Trainer is designed to provide kinematic constraint to the paretic lower limb, to guide a physiologically normal and symmetrical gait pattern. The purpose of this pilot study was to assess the immediate influence of the Re-Link Trainer on measures of gait symmetry in healthy adults. Participants demonstrated a significantly lower cadence and a 62% reduction in walking speed in the Re-Link Trainer compared to normal walking. The step length ratio had a significant increase from 1.0 during normal walking to 2.5 when walking in the Re-Link Trainer. The results from this pilot study suggest in its current iteration the Re-Link Trainer imposes an asymmetrical constraint on lower limb kinematics.

Rubber acid damage in fire hoses

Energy Technology Data Exchange (ETDEWEB)

Thaysen, A C; Bunker, H J; Adams, M E

1945-03-17

Hose failure observed in rubber-lined fire hoses may be due to sulfuric acid formed from sulfur present in hoses when they are not properly dried. Microorganisms were observed in numerous samples of hose liquid and as a result of the experiments which were carried it was concluded that: the production of rubber acid in hose is due to the activity of sulfur-oxidizing bacteria of the Thiobacterium thiooxidans group. Such acid will invariably be formed when the hoses are stored with the linings wet, when the responsible bacteria are present and when the free sulfur content of the hoses exceeds 0.1 precent. The alternative of preventing the introduction of the causal bacteria does not appear practical since the water used in fire-fighting in the London district is taken from static supplies.

2012-05-01

Full Text Available Different land cover types are related to different levels of fire hazard through their vegetation structure and fuel load composition. Therefore, understanding the relationships between landscape changes and fire behavior is of crucial importance for developing adequate fire fighting and fire prevention strategies for a changing world. In the last decades the abandonment of agricultural lands and pastoral activities has been the major driver of landscape transformations in Mediterranean Europe. As agricultural land abandonment typically promotes an increase in plant biomass (fuel load, a number of authors argue that vegetation succession in abandoned fields and pastures is expected to increase fire hazard. In this short paper, based on 28 493 fires in Sardinia (Italy in the period 2001–2010, we show that there is no evidence of increased probability of fire ignition in abandoned rural areas. To the contrary, in Sardinia the decreased human impact associated with agricultural land abandonment leads to a statistically significant decrease of fire ignition probability.

Full Text Available Fire is one of the most dangerous phenomena in the world which yields main damages, healthy and economical, and is thus a major threat to hospitals. Since, most of the residents in hospitals are the individuals who cannot rescue themselves in such situations, fire in hospitals is more hazardous than any other public place; hence, it can endanger several sophisticated medical equipment. Therefore, security against fire plays a very vital role in hospitals and has to be taken into account by authorities. Among the personnel, hospital manager and the security guard supervisor are much more responsible. One of their responsibilities includes planning fire security scheme in hospitals to reduce the death rate caused by fire so that there is less threat to the building of hospital admits content. Due to the significance of this issue in hospitals, it seems necessary for the personnel to be aware of security measures against fire. Therefore, a study was carried out in Isfahan University of Medical Sciences teaching hospitals on all managers, their awareness about this issue was measured through a questionnaire. The results indicated that of a total of 60, the obtained average was (37.63+7.36 in the medium level. Also, most of the managers believed that proper and updated training by skillful trainers regarding hospital security measures and its application can be truly effective on their productivity. Thus, it is concluded that practical training the mentioned target group (hospital personnel especially clerks and the managers about the security plans can be effective in the control of fire and security measures, resulting in reduction of accidents and human and economic loss in the future.

Report on full-scale horizontal cable tray fire tests, FY 1988

In recent years, there has been much discussion throughout industry and various governmental and fire protection agencies relative to the flammability and fire propagation characteristics of electrical cables in open cable trays. It has been acknowledged that under actual fire conditions, in the presence of other combustibles, electrical cable insulation can contribute to combustible fire loading and toxicity of smoke generation. Considerable research has been conducted on vertical cable tray fire propagation, mostly under small scale laboratory conditions. In July 1987, the Fermi National Accelerator Laboratory initiated a program of full scale, horizontal cable tray fire tests, in the absence of other building combustible loading, to determine the flammability and rate of horizontal fire propagation in cable tray configurations and cable mixes typical of those existing in underground tunnel enclosures and support buildings at the Laboratory. The series of tests addressed the effects of ventilation rates and cable tray fill, fire fighting techniques, and effectiveness and value of automatic sprinklers, smoke detection and cable coating fire barriers in detecting, controlling or extinguishing a cable tray fire. This report includes a description of the series of fire tests completed in June 1988, as well as conclusions reached from the test results

Ekegren, C L; Gabbe, B J; Finch, C F

2015-06-01

A lack of available injury data on community sports participants has hampered the development of informed preventive strategies for the broad-base of sports participation. In community sports settings, sports trainers or first-aiders are well-placed to carry out injury surveillance, but few studies have evaluated their ability to do so. The aim of this study was to investigate the reporting rate and completeness of sports trainers' injury records and agreement between sports trainers' and players' reports of injury in community Australian football. Throughout the football season, one sports trainer from each of four clubs recorded players' injuries. To validate these data, we collected self-reported injury data from players via short message service (SMS). In total, 210 discrete injuries were recorded for 139 players, 21% by sports trainers only, 59% by players via SMS only, and 21% by both. Completeness of injury records ranged from 95% to 100%. Agreement between sports trainers and players ranged from K = 0.32 (95% confidence interval: 0.27, 0.37) for date of return to football to K = 1.00 for activity when injured. Injury data collected by sports trainers may be of adequate quality for providing an understanding of the profile of injuries. However, data are likely to underestimate injury rates and should be interpreted with caution. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Trainer variability during step training after spinal cord injury: Implications for robotic gait-training device design.

Galvez, Jose A; Budovitch, Amy; Harkema, Susan J; Reinkensmeyer, David J

2011-01-01

Robotic devices are being developed to automate repetitive aspects of walking retraining after neurological injuries, in part because they might improve the consistency and quality of training. However, it is unclear how inconsistent manual training actually is or whether stepping quality depends strongly on the trainers' manual skill. The objective of this study was to quantify trainer variability of manual skill during step training using body-weight support on a treadmill and assess factors of trainer skill. We attached a sensorized orthosis to one leg of each patient with spinal cord injury and measured the shank kinematics and forces exerted by different trainers during six training sessions. An expert trainer rated the trainers' skill level based on videotape recordings. Between-trainer force variability was substantial, about two times greater than within-trainer variability. Trainer skill rating correlated strongly with two gait features: better knee extension during stance and fewer episodes of toe dragging. Better knee extension correlated directly with larger knee horizontal assistance force, but better toe clearance did not correlate with larger ankle push-up force; rather, it correlated with better knee and hip extension. These results are useful to inform robotic gait-training design.

Fire extinguishing of electrical equipment under voltage at nuclear power plants

International Nuclear Information System (INIS)

Capek, Josef

2009-01-01

Fire extinguishing on equipment that is under voltage is always hazardous. Conventional fire fighting equipment applicable to this task includes powder and gas extinguishers, which, however, have some drawbacks. Therefore, attention has been increasingly devoted to high-pressure fire extinguishing, whose assets include better heat removal as compared to a full water flow where the majority of the water runs off without any cooling effect. This article describes the testing of some types and combinations of extinguishing techniques and their interpretation based on earth-leakage current measurement and determination of a safe distance for fire extinguishing. Methodology described in CSN IEC 60-1:1994 and CSN EN 3-7:2004 was applied. To meet the criterion, none of the tests was to exhibit an earth-leakage current higher than 0.5 mA. In the accredited laboratory test room setup, 3 extinguishing equipment arrangements proved to extinguish fire on electrical equipment under voltage at a safe distance of 1 m (or 3 m). (orig.)

1982-01-01

An operator trainer module has been developed to be used with the security control center equipment to be installed as part of a safeguards physical protection system. The module is designed to provide improved training and testing capabilities for control center operators through the use of simulations for perimeter equipment operations. Operators, through the trainer module, can be challenged with a variety of realistic situations which require responsive action identical to that needed in an actual system. This permits a consistent evaluation and confirmation of operator capabilities prior to assignment as an operator and allows for periodic retesting to verify that adequate performance levels are maintained

First-aid is a recommended injury prevention and risk management strategy in community sport; however, little is known about the sport-specific competencies required by first-aid providers. To achieve expert consensus on the competencies required by community Australian Football (community-AF) sports trainers. A three-round online Delphi process. Community-AF. 16 Australian sports first-aid and community-AF experts. Rating of competencies as either 'essential', 'expected', 'ideal' or 'not required'. Results After Round 3, 47 of the 77 (61%) competencies were endorsed as 'essential' or 'expected' for a sports trainer to effectively perform the activities required to the standards expected at a community-AF club by ≥75% of experts. These competencies covered: the role of the sports trainer; the responsibilities of the sports trainer; emergency management; injury and illness assessment and immediate management; taping; and injury prevention and risk management. Four competencies (5%) were endorsed as 'ideal' or 'not required' by ≥85% of experts and were excluded from further consideration. The 26 competencies where consensus was not reached were retained as second-tier, optional competencies. Sports trainers are important members of on-field first-aid teams, providing support to both injured players and other sports medicine professionals. The competencies identified in this study provide the basis of a proposed two-tiered community-AF-specific sports trainer education structure that can be implemented by the peak sports body. This includes six mandatory modules, relating to the 'required' competencies, and a further six optional modules covering competencies on which consensus was not reached.

To present best-practice recommendations for the prevention, recognition, and treatment of exertional heat illnesses (EHIs) and to describe the relevant physiology of thermoregulation. Certified athletic trainers recognize and treat athletes with EHIs, often in high-risk environments. Although the proper recognition and successful treatment strategies are well documented, EHIs continue to plague athletes, and exertional heat stroke remains one of the leading causes of sudden death during sport. The recommendations presented in this document provide athletic trainers and allied health providers with an integrated scientific and clinically applicable approach to the prevention, recognition, treatment of, and return-to-activity guidelines for EHIs. These recommendations are given so that proper recognition and treatment can be accomplished in order to maximize the safety and performance of athletes. Athletic trainers and other allied health care professionals should use these recommendations to establish onsite emergency action plans for their venues and athletes. The primary goal of athlete safety is addressed through the appropriate prevention strategies, proper recognition tactics, and effective treatment plans for EHIs. Athletic trainers and other allied health care professionals must be properly educated and prepared to respond in an expedient manner to alleviate symptoms and minimize the morbidity and mortality associated with these illnesses.

Wildfires continue to cause damage to property, livelihoods and environments around the world. Acknowledging that dealing with wildfires has to go beyond fire-fighting, governments in countries with fire-prone ecosystems have begun to recognize the multiple perspectives of landscape burning and the need to engage with local communities and their practices. In this perspective, we outline the experiences of Brazil and Venezuela, two countries where fire management has been highly contested, but where there have been recent advances in fire management approaches. Success of these new initiatives have been measured by the reduction in wildfire extent through prescribed burning, and the opening of a dialogue on fire management between government agencies and local communities. Yet, it is clear that further developments in community participation need to take place in order to avoid the appropriation of local knowledge systems by institutions, and to better reflect more equitable fire governance.

intelligent virtual agents (IVAs) with human appearance and the capability to teach foreign language vocabulary. We report results from studies that we have conducted with Billie, an IVA employed as a vocabulary trainer, as well as research findings on the acceptance of the agent as a trainer by adults and children. The results show that Billie can train humans as well as a human teacher can and that both adults and children accept the IVA as a trainer. The advantages of IVAs are multiple. First, their teaching methods can be based on neuropsychological research findings concerning memory and learning practice. Second, virtual teachers can provide individualized training. Third, they coach users during training, are always supportive, and motivate learners to train. Fourth, agents will reside in the user's mobile devices and thus be at the user's disposal everywhere and anytime. Agents in apps will make foreign language training accessible to anybody at low cost. This will enable people around the world, including physically, financially, and geographically disadvantaged persons, to learn a foreign language and help to facilitate multilingualism.

An Emergency-Adaptive Routing Scheme for Wireless Sensor Networks for Building Fire Hazard Monitoring

Directory of Open Access Journals (Sweden)

Guilin Zheng

2011-03-01

Full Text Available Fire hazard monitoring and evacuation for building environments is a novel application area for the deployment of wireless sensor networks. In this context, adaptive routing is essential in order to ensure safe and timely data delivery in building evacuation and fire fighting resource applications. Existing routing mechanisms for wireless sensor networks are not well suited for building fires, especially as they do not consider critical and dynamic network scenarios. In this paper, an emergency-adaptive, real-time and robust routing protocol is presented for emergency situations such as building fire hazard applications. The protocol adapts to handle dynamic emergency scenarios and works well with the routing hole problem. Theoretical analysis and simulation results indicate that our protocol provides a real-time routing mechanism that is well suited for dynamic emergency scenarios in building fires when compared with other related work.

General Practitioner trainers prescribe fewer antibiotics in primary care: Evidence from France.

2018-01-01

Antibiotic prescription is a central public health issue. Overall, 90% of antibiotic prescriptions are delivered to patients in ambulatory care, and a substantial proportion of these prescriptions could be avoided. General Practitioner (GP) trainers are similar to other GPs in terms of sociodemographic and medical activities, but they may have different prescription patterns. Our aim was to compare the antibiotic prescribing rates between GP trainers and non-trainers. This observational cross-sectional study was conducted on administrative data claims from the French National Health Insurance. The antibiotic prescribing rate was calculated. The main independent variable was the training status of the GPs. Prescribing rates were adjusted for the various GPs' characteristics (gender, age, location of the practice, number of visits per GP and the case-mix) in a multiple linear regression analysis. Between June 2014 and July 2015 the prescribing patterns of 860 GPs were analysed, among which 102 were GP trainers (12%). Over the year 363,580 patients were prescribed an antibiotic out of 3,499,248 visits for 1,299,308 patients seen over the year thus representing around 27.5% of patients. In the multivariate analyses, being a trainer resulted in a significant difference of 6.62 percentage points (IC 95%: [-8.55; -4.69]; prole of GP trainers in antibiotic prescriptions. By prescribing fewer antibiotics and influencing the next generations of GPs, the human and economic burden of antibiotics could be reduced.

Current Status of Fire Risk Assessment in Germany

International Nuclear Information System (INIS)

Berg, H. P.

2002-01-01

The approach for fire risk assessment to be applied within periodic safety reviews of nuclear power plants in Germany starts with a screening process providing critical fire zones in which a fully developed fire has the potential to both cause an initiating event and impair the function of at least one component or system critical to safety. The second step is to perform a quantitative analysis. For that purpose, a standard event tree has been developed with elements for fire initiation, ventilation of the room, fire detection, fire suppression, and fire propagation. This standard event tree has to be adapted to each critical fire zone or room. In a final step, the fire induced frequency of initiating events, the main contributors and the calculated hazard state frequency for the fire event are determined. In order to perform a quantitative fire risk assessment, a basic data base must be established which should, e.g., include initiating frequencies, reliability data for all fire protection measures, fire barriers, etc. Detailed plant-specific information is needed on ignition sources, detection and extinguishing systems, manual fire fighting, stationary fire suppression systems. As one contributor to fire specific PSA input data, reliability data for the active fire protection measures are required for the application in the fire specific event tree analysis. These data needed to be estimated are unavailabilities per demand or failure rates per hour of plant operation for those components or systems belonging to the active fire protection means. The data on potential failures or unavailabilities per demand of the respective fire protection measures were gained from the plant specific documentation of inspection and maintenance. The assessment whether the detected findings are estimated as failures or only as deficiencies or deteriorations requires a deep insight in the plant specific operating conditions for the fire protection means and needs careful engineering

Russo, Ana; Ramos, Alexandre; Trigo, Ricardo

2013-04-01

Wildfires in southern Europe cause frequent extensive economical and ecological losses and, even human casualties. Comparatively to other Mediterranean countries, Portugal is the country with more burnt area and fires per unit area in the last decade, mainly during the summer season (Pereira et al., 2011). According to the fire records available, between 1980 and 2009, wildfires have affected over 3 million hectares in Portugal (JRC, 2011), which corresponds to approximately a third of the Portuguese Continental territory. The main factors that influence fire ignition and propagation are: (1) the presence of fuel (i.e. vegetation); (2) climate and weather; (3) socioeconomic conditions that affect land use/land cover patterns, fire-prevention and fire-fighting capacity and (4) topography. Specifically, weather (e.g. wind, temperature, precipitation, humidity, and lightning occurrence) plays an important role in fire behavior, affecting both ignition and spread of wildfires. Some countries have a relatively large fraction of fires caused by lightning, e.g. northwestern USA, Canada, Russia (). In contrast, Portugal has only a small percentage of fire records caused by lightning. Although significant doubts remain for the majority of fires in the catalog since they were cataloged without a likely cause. The recent years of 2003 and 2005 were particularly outstanding for fire activity in Portugal, registering, respectively, total burned areas of 425 726 ha and 338 262 ha. However, while the 2003 was triggered by an exceptional heatwave that struck the entire western Europe, the 2005 fire season registered was coincident with one of the most severe droughts of the 20th century. In this work we have used mainly two different databases: 1) the Portuguese Rural Fire Database (PRFD) which is representative of rural fires that have occurred in Continental Portugal, 2001-2011, with the original data provided by the Autoridade Florestal Nacional (AFN, 2011); 2) lightning

This paper presents the results we obtained in the context of the FIRE-SAT project during the 2012 operative application of the satellite based tools for fire monitoring. FIRE_SAT project has been funded by the Civil Protection of the Basilicata Region in order to set up a low cost methodology for fire danger monitoring and fire effect estimation based on satellite Earth Observation techniques. To this aim, NASA Moderate Resolution Imaging Spectroradiometer (MODIS), ASTER, Landsat TM data were used. Novel data processing techniques have been developed by researchers of the ARGON Laboratory of the CNR-IMAA for the operative monitoring of fire. In this paper we only focus on the danger estimation model which has been fruitfully used since 2008 to 2012 as an reliable operative tool to support and optimize fire fighting strategies from the alert to the management of resources including fire attacks. The daily updating of fire danger is carried out using satellite MODIS images selected for their spectral capability and availability free of charge from NASA web site. This makes these data sets very suitable for an effective systematic (daily) and sustainable low-cost monitoring of large areas. The preoperative use of the integrated model, pointed out that the system properly monitor spatial and temporal variations of fire susceptibility and provide useful information of both fire severity and post fire regeneration capability.

Umbers, Kate D. L.; Tatarnic, Nikolai J.; Holwell, Gregory I.; Herberstein, Marie E.

2012-01-01

Contests among individuals over mating opportunities are common across diverse taxa, yet physical conflict is relatively rare. Due to the potentially fatal consequences of physical fighting, most animals employ mechanisms of conflict resolution involving signalling and ritualistic assessment. Here we provide the first evidence of ubiquitous escalated fighting in grasshoppers. The chameleon grasshopper (Kosciuscola tristis) is an Australian alpine specialist, in which males engage in highly aggressive combat over ovipositing females. We describe discrete agonistic behaviours including mandible flaring, mounting, grappling, kicking and biting, and their use depending on the individual’s role as challenger or defender. We show that male role predicts damage, with challengers being more heavily damaged than males defending females (defenders). Challengers also possess wider mandibles than defenders, but are similar in other metrics of body size. Our data suggest that fights escalate between males matched in body size and that mandibles are used as weapons in this species. This system represents an exciting opportunity for future research into the evolution of costly fighting behaviour in an otherwise placid group. PMID:23166725

This system represents an exciting opportunity for future research into the evolution of costly fighting behaviour in an otherwise placid group.

Applicability of the 'constructional fire prevention for industrial plants' to power plants

International Nuclear Information System (INIS)

Hammacher, P.

1978-01-01

Power plants, especially nuclear power plants, are considered because of their high value and large construction volume to be among the most important industrial constructions of our time. They have a very exposed position from the point of view of fire prevention because of their constructional and operational concept. The efforts in the Federal Republic of Germany to standardize laws and regulations for fire prevention in industrial plants (industrial construction code, DIN 18230) must be supported if only because they would simplify the licensing procedure. However these regulations cannot be applied in many cases and especially in the main buildings of thermal power plants without restricting or even endangering the function or the safety of such plants. At the present state of the art many parts of the power plant can surely be defined as 'fire safe'. Fire endangered plant components and rooms are protected according to their importance by different measures (constructional measures, fire-fighting equipments, extractors for flue gases and for heat, fire-brigade of the plant).

Kosiewicz Jerzy

2018-03-01

Full Text Available In the presented text the author points out to anthropological as well as axiological foundations of the boxing fight from the viewpoint of Hegel’s philosophy. In the genial idealist’s views it is possible to perceive the appreciation of the body, which constitutes a necessary basis for the man’s physical activity, for his work oriented towards the self-transformation and the transformation of the external world, as well as for rivalry and the hand-to-hand fight. While focusing our attention on the issue of rivalry and on the situation of the fight - and regarding it from the viewpoint of the master - slave theory (included in the phenomenology of spirit, it is possible to proclaim that even a conventionalised boxing fight - that is, restricted by cultural and sports rules of the game - has features of the fight to the death between two Hegelian forms of selfknowledge striving for self-affirmation and self-realisation. In the boxing fight, similarly as in the above mentioned Hegelian theory, a problem of work and of the development of the human individual (that is, of the subject, self-knowledge, the participant of the fight appears. There appears also a prospect of death as a possible end of merciless rivalry. The fight revalues the human way in an important way, whereas the prospect for death, the awareness of its proximity, the feeling that its close and possible, saturates the life with additional values. It places the boxer, just like every subject fighting in a similar or a different way, on the path towards absolute abstraction - that is, it brings him closer to his self-fulfilment in the Absolute, to the absolute synthesis. The Hegelian viewpoint enables also to appreciate the boxing fight as a manifestation of low culture (being in contrast with high culture, to turn attention to the relations which - according to Hegel - take place between the Absolute and the man, as well as to show which place is occupied by the subject both in

Fire evolved on the earth under the direct influence of climate and the accumulation of burnable biomass at various times and spatial scales. As a result, fire regimes depend not only on climatic and biological factors, but also greatly reflect the cultural background of how people do manage ecosystems and fire. A new awareness among scientists and managers has been rising about the ecological role of fire and the necessity to understand its past natural and cultural dynamics in different ecosystems, in order to preserve present ecosystem functionality and minimize management costs and negative impacts. As a consequence we assisted in the last decades to a general shift from the fire control to the fire management approach, where fire prevention, fire danger rating, fire ecology, fire pre-suppression and suppression strategies are fully integrated in the landscape management. Nowadays, a large number of authors recognize that a total suppression strategy, as the one adopted during last decades, leads to a fire paradox: the more we fight for putting out all fires, the more extreme events occur and cause long term damages. The aim of this review is to provide a state of art about the connection between fire, humans and landscape, along time and space. Negative and positive impacts on ecosystem services and values are put in evidence, as well as their incidence on human aptitude to fire use as to fire suppression. In order to capture a consistent fragment of fire history, palaeofires and related palynological studies are considered. They enable a valuable, even if partial, look at the millenary fire regime. Actual strategies and future directions are described in order to show what are the alternatives for living with fire, since removing completely this disturbance from earth is not a option, nor feasible neither advisable. Examples from the world, in particular from the Alps and the Mediterranean basin, are shown for better illustrating the signature of

Full Text Available Firemen threat during fire burning of chemical substances indicated presence of carbon monoxide (CO in all cases. Carbon monoxide causes death of fire. Inhaled through respiratory system, links with hemoglobin, thus blocking transport and distribution of oxygen in the body. This leads to tissue anoxia, which is a direct threat to firefighters’ life. The purpose of this study was to assess the exposure to carbon monoxide of participating firefighters extinguishing fire. Estimation of carbon monoxide quantity absorbed by firefighters was isolated in a group of 40 firefighters from Fire Extinguishing and Rescue Unit of State Fire in Nysa. The study was conducted by measuring carbon monoxide in exhaled air. For measurement of carbon monoxide concentration in exhaled air Micro CO meter was used. Results were demonstrated separately for nonsmokers (n425 and smokers (n415. Mean COHb[%] levels in nonsmokers, measured prior the rescue action was 0,3950,3% and increased statistically significant after the action to 0,6150,34%, while in the group smokers, this level was 2,1750,64% before the action and increased insignificantly after the action to 2,3350,63%. The average COHb level in the same groups before and after exercise, was respectively: for nonsmokers prior to exercise was 0,4850,28% and after exercise decreased statistically significant to 0,3050,27%. In the group of smokers before exercise was 2,2350,61% and decreased statistically significant up to 1,5450,71%. It was no difference between the group of age and time of employment.

2018-02-01

In the last decade we have witnessed an increasing interest in using computer vision and image processing in forest fire research. Image processing techniques have been successfully used in different fire analysis areas such as early detection, monitoring, modeling and fire front characteristics estimation. While the majority of the work deals with the use of 2D visible spectrum images, recent work has introduced the use of 3D vision in this field. This work proposes a new multimodal vision framework permitting the extraction of the three-dimensional geometrical characteristics of fires captured by multiple 3D vision systems. The 3D system is a multispectral stereo system operating in both the visible and near-infrared (NIR) spectral bands. The framework supports the use of multiple stereo pairs positioned so as to capture complementary views of the fire front during its propagation. Multimodal registration is conducted using the captured views in order to build a complete 3D model of the fire front. The registration process is achieved using multisensory fusion based on visual data (2D and NIR images), GPS positions and IMU inertial data. Experiments were conducted outdoors in order to show the performance of the proposed framework. The obtained results are promising and show the potential of using the proposed framework in operational scenarios for wildland fire research and as a decision management system in fighting.

The Robotic Gait Rehabilitation (RGR) Trainer targets secondary gait deviations in stroke survivors undergoing rehabilitation. Using an impedance control strategy and a linear electromagnetic actuator, the device generates a force field to control pelvic obliquity through a Human-Machine Interface (i.e. a lower body exoskeleton). Herein we describe the design of the RGR Trainer Human-Machine Interface (HMI) and we demonstrate the system's ability to alter the pattern of movement of the pelvis during gait in a healthy subject. Results are shown for experiments during which we induced hip-hiking - in healthy subjects. Our findings indicate that the RGR Trainer has the ability of affecting pelvic obliquity during gait. Furthermore, we provide preliminary evidence of short-term retention of the modified pelvic obliquity pattern induced by the RGR Trainer. © 2011 IEEE

Challenges to fire protection measures at Hamaoka Nuclear Power Station

International Nuclear Information System (INIS)

Narama, Takeshi

2015-01-01

New regulatory standards for fire protection at nuclear power plants have been established by the Nuclear Regulation Authority. This paper introduces the measures taken by the Hamaoka Nuclear Power Station for the following four items, which were especially big changes. (1) To install a combination of sensors of different types or instruments with equivalent functions so as to be able to emit unique signals to inform a fire in the early stage. (2) To conduct 'UL vertical burn test' as the demonstration test for self-extinguishing performance as the condition for flame-retardant cable. (3) To install automatic fire-extinguishers or fixed fire-extinguishing devices of manual type at the spots where fire-fighting is difficult due to the filling of smoke in a fire or the effect of radiation. (4) To separate the system for purpose of ensuring safety function to attain the high-temperature shutdown and cold-temperature shutdown of a reactor whatever fire may happen at the nuclear facilities. The examples of the installation of fire-extinguishers as the measures for the above Item (3) are as follows; (A) as for the devices containing oil, a foam-extinguishing agent is released against each target device from the nozzle, and (B) for large vertical pump motors indoors and relatively small pump motors, IA type automatic foam extinguishing systems are installed.

Due to the high prevalence of prescription opioid misuse, the US Food and Drug Administration (FDA) mandated a Risk Evaluation and Mitigation Strategy (REMS) requiring manufacturers of extended-release/long-acting (ER/LA) opioids to fund continuing education based on an FDA curricular Blueprint. This paper describes the Safe and Competent Opioid Prescribing Education (SCOPE of Pain) train-the-trainer program and its impact on (1) disseminating the SCOPE of Pain curriculum and (2) knowledge, confidence, attitudes, and performance of the participants of trainer-led compared with expert-led meetings. SCOPE of Pain is a 3-hour ER/LA opioid REMS education. In addition to expert-led live statewide meetings, a 2-hour train-the-trainer (TTT) workshop was developed to increase dissemination nationally. The trainers were expected to conduct SCOPE of Pain meetings at their institutions. Participants of both the trainer-led and expert-led SCOPE of Pain programs were surveyed immediately post and 2 months post meetings to assess improvements in knowledge, confidence, attitudes, and self-reported safe opioid prescribing practices. During 9 months (May 2013 to February 2014), 89 trainers were trained during 9 TTT workshops in 9 states. Over 24 months (May 2013 to April 2015), 33% of the trainers conducted at least 1 SCOPE of Pain training, with a total of 79 meetings that educated 1419 participants. The average number of meetings of those who conducted at least 1 meeting was 2.8 (range: 1-19). The participants of the trainer-led programs were significantly more likely to be practicing in rural settings than those who participated in the expert-led meetings (39% vs. 26%, P strategy to increase guideline-based safe opioid prescribing knowledge, confidence, attitudes, and self-reported practices.

Smouldering Subsurface Fires in the Earth System

Science.gov (United States)

Rein, Guillermo

2010-05-01

Smouldering fires, the slow, low-temperature, flameless form of combustion, are an important phenomena in the Earth system. These fires propagate slowly through organic layers of the forest ground and are responsible for 50% or more of the total biomass consumed during wildfires. Only after the 2002 study of the 1997 extreme haze event in South-East Asia, the scientific community recognised the environmental and economic threats posed by subsurface fires. This was caused by the spread of vast biomass fires in Indonesia, burning below the surface for months during the El Niño climate event. It has been calculated that these fires released between 0.81 and 2.57 Gton of carbon gases (13-40% of global emissions). Large smouldering fires are rare events at the local scale but occur regularly at a global scale. Once ignited, they are particularly difficult to extinguish despite extensive rains or fire-fighting attempts and can persist for long periods of time (months, years) spreading over very extensive areas of forest and deep into the soil. Indeed, these are the oldest continuously burning fires on Earth. Earth scientists are interested in smouldering fires because they destroy large amounts of biomass and cause greater damage to the soil ecosystem than flaming fires do. Moreover, these fires cannot be detected with current satellite remote sensing technologies causing inconsistencies between emission inventories and model predictions. Organic soils sustain smouldering fire (hummus, duff, peat and coal) which total carbon pool exceeds that of the world's forests or the atmosphere. This have important implications for climate change. Warmer temperatures at high latitudes are resulting in unprecedented permafrost thaw that is leaving large soil carbon pools exposed to fires. Because the CO2 flux from peat fires has been measured to be about 3000 times larger that the natural degradation flux, permafrost thaw is a risk for greater carbon release by fire and subsequently

Full Text Available The seasonal profession of wildland fire fighting in Canada requires individuals to work in harsh environmental conditions that are physically demanding. The purpose of this study was to use novel technologies to evaluate the physiological demands and nutritional practices of Canadian FireRangers during fire deployments.Participants (n = 21 from a northern Ontario Fire Base volunteered for this study and data collection occurred during the 2014 fire season and included Initial Attack (IA, Project Fire (P, and Fire Base (B deployments. Deployment-specific energy demands and physiological responses were measured using heart-rate variability (HRV monitoring devices (Zephyr BioHarness3 units. Food consumption behaviour and nutrient quantity and quality were captured using audio-video food logs on iPod Touches and analyzed by NutriBase Pro 11 software.Insufficient kilocalories were consumed relative to expenditure for all deployment types. Average daily kilocalories consumed: IA: 3758 (80% consumption rate; P: 2945±888.8; B: 2433±570.8. Average daily kilocalorie expenditure: IA: 4538±106.3; P: 4012±1164.8; B: 2842±649.9. The Average Macronutrient Distribution Range (AMDR for protein was acceptable: 22-25% (across deployment types. Whereas the AMDR for fat and carbohydrates were high: 40-50%; and low: 27-37% respectively, across deployment types.This study is the first to use the described methodology to simultaneously evaluate energy expenditures and nutritional practices in an occupational setting. The results support the use of HRV monitoring and video-food capture, in occupational field settings, to assess job demands. FireRangers expended the most energy during IA, and the least during B deployments. These results indicate the need to develop strategies centered on maintaining physical fitness and improving food practices.

Full Text Available Background: The dental clinical setting, which is a significant learning environment for undergraduate dental students, may induce anxiety, which may adversely affect the clinical performance. The purpose of this cross-sectional study was to determine the factors provoking clinical anxiety in dental students from the trainers and students perspectives. Materials and Methods: This cross-sectional study was conducted among 6 th (final year dental students of University of Benin and their clinical trainers between January and March 2012 using the 38-item modified Moss and McManus clinical anxiety questionnaire. Results: Of the 67 participants, 32 (47.8% were 6 th year dental students while 35 (52.2% were clinical trainers. According to the students, the top clinical anxiety provoking situations were inability to meet requirements before exams, inability to pass the final exams, dealing with psychiatric patients, coping with uncooperative children, getting infected by patients, fracturing a tooth during extraction, extracting the wrong tooth, discovering calculus by the supervisor after scaling, accidental pulp exposure, inadvertently hurting patients and using the high speed hand piece. There existed concordance on the top two clinical anxiety provoking situations reported by the students and their clinical trainers. However, measuring blood pressure, taking pulse, presenting in the clinic, handling a syncopal attack, and accidental pulp exposure were statistically significant contrasting clinical anxiety provoking situations from dental students and trainers perspectives. Conclusion: Data from this study revealed that clinical trainers share largely the same perspectives with the dental students on the clinical anxiety provoking situations with slight variations. Fostering a supportive learning environment conducive to dental student learning by strengthen efforts to minimize clinical anxiety is a necessity.

Characterization of a mine fire using atmospheric monitoring system sensor data.

2017-06-01

Atmospheric monitoring systems (AMS) have been widely used in underground coal mines in the United States for the detection of fire in the belt entry and the monitoring of other ventilation-related parameters such as airflow velocity and methane concentration in specific mine locations. In addition to an AMS being able to detect a mine fire, the AMS data have the potential to provide fire characteristic information such as fire growth - in terms of heat release rate - and exact fire location. Such information is critical in making decisions regarding fire-fighting strategies, underground personnel evacuation and optimal escape routes. In this study, a methodology was developed to calculate the fire heat release rate using AMS sensor data for carbon monoxide concentration, carbon dioxide concentration and airflow velocity based on the theory of heat and species transfer in ventilation airflow. Full-scale mine fire experiments were then conducted in the Pittsburgh Mining Research Division's Safety Research Coal Mine using an AMS with different fire sources. Sensor data collected from the experiments were used to calculate the heat release rates of the fires using this methodology. The calculated heat release rate was compared with the value determined from the mass loss rate of the combustible material using a digital load cell. The experimental results show that the heat release rate of a mine fire can be calculated using AMS sensor data with reasonable accuracy.

Communication between trainer and trainee plays a central role in teaching and learning in the clinical environment. There are various strategies to frame the dialogue between trainee and trainer. These strategies allow trainers to be more effective in their supervision, which is important in our busy clinical environment. Communication strategies are well adapted to both in- and out-patient settings, to both under- and postgraduate contexts. This article presents three strategies that we think are particularly useful. They are meant to give feedback, to ask questions and to present a case.

The turbine oil fire in the nuclear power plant, Muehleberg

Lutz, H.R.

1972-01-01

At 21.15 hours on the evening of the 28th July 1971, a turbine oil fire broke out in the Nuclear Power Plant Muehleberg of the Bernische Kraftwerke AG, resulting in damage amounting to around 20 million Swiss Francs and a delay of some ten months in putting the plant into operation. The plant is equipped with a General Electric boiling water reactor and two BBC saturated steam turbines. Up to the time of the fire, both turbo-sets had already been run singly up to their full capacity of 160 MWe and the initial trials with both sets working parallel were shortly due to be carried out. Following the outbreak of fire, the causes of which are described in the contributions of the authors Hagn, L. and H. Huppmann and Christian, H. and H. Grupp, fire fighting action was immediately taken, in line with the emergency measures laid down in the operating regulations. With the assistance of the Berne City Fire Brigade, the blaze in the roof of the turbine hall was first extinguished and the spreading cable conflagration then fought, using foam and water. (orig.)

The objective of this study was to test the feasibility and acceptability of a new workers' health surveillance (WHS) for fire fighters in a Dutch pilot-implementation project. In three fire departments, between November 2007 and February 2009, feasibility was tested with respect to i) worker intent to change health and behavior; ii) the quality of instructions for testing teams; iii) the planned procedure in the field; and iv) future WHS organisation. Acceptability involved i) satisfaction with WHS and ii) verification of the job-specificity of the content of two physical tests of WHS. Fire fighters were surveyed after completing WHS, three testing teams were interviewed, and the content of the two tests was studied by experts. nearly all of the 275 fire fighters intended to improve their health when recommended by the occupational physician. The testing teams found the instructions to be clear, and they were mostly positive about the organisation of WHS. Acceptability: the fire fighters rated WHS at eight points (out of a maximum of ten). The experts also reached a consensus about the optimal job-specific content of the future functional physical tests. Overall, it is feasible and acceptable to implement WHS in a definitive form in the Dutch fire-fighting sector.

  Environmental sustainability efforts are becoming a critical concern in health care. However, little is known regarding how athletic trainers feel about the environment or what can be done to reduce the environmental impact of the practice of athletic training.   To examine athletic trainers' attitudes toward and perceptions of factors related to environmental sustainability.   Sequential, mixed methods using a survey, focus groups, and personal interviews.   Field study.   Four hundred forty-two individuals completed the survey. Sixteen participated in the qualitative portion.   Quantitative results from the Athletic Training Environmental Impact Survey included data from a 5-point Likert scale (1 = lowest rating and 5 = highest rating). Descriptive statistics and 1-way analyses of variance were used to describe perceptions and determine differences in mean opinion, National Athletic Trainers' Association district, and use of green techniques. Qualitative data were transcribed verbatim and analyzed inductively.   The mean score for opinion of the environment was 3.30 ± 0.52. A difference was found between opinion and National Athletic Trainers' Association district ( F 9, 429 = 2.43, P = .01). A Bonferroni post hoc analysis identified this difference ( P = .03) between members of District 2 (Delaware, New Jersey, New York, Pennsylvania) and District 9 (Alabama, Florida, Georgia, Kentucky, Louisiana, Mississippi, Tennessee). An inductive analysis resulted in 3 emergent themes: (1) barriers to using green techniques, (2) motivators for using green techniques, and (3) solutions to overcoming the barriers. The information gleaned from participants in the qualitative portion of the study can be useful for clinicians wishing to implement basic conservation efforts in their practice settings and may guide future sustainability projects.   Overall, participants reported a positive opinion of environmental sustainability topics related to athletic

Modern concepts of gait rehabilitation after stroke favor a task-specific repetitive approach. In practice, the required physical effort of the therapists limits the realization of this approach. Therefore, a mechanized gait trainer enabling nonambulatory patients to have the repetitive practice of a gait-like movement without overstraining therapists was constructed. This preliminary study investigated whether an additional 4-week daily therapy on the gait trainer could improve gait ability in 14 chronic wheelchair-bound hemiparetic subjects. The 4 weeks of physiotherapy and gait-trainer therapy resulted in a relevant improvement of gait ability in all subjects. Velocity, cadence, and stride length improved significantly (p gait trainer seems feasible as an adjunctive tool in gait rehabilitation after stroke; further studies are needed.

Analysis of Moisture Evaporation from Underwear Designed for Fire-Fighters

Full Text Available In this study we analysed the effect of moisture on the thermal protective performance of fire-fighter clothing in case of routine fire-fighting conditions. In the first stage of this research we investigated simultaneous heat and moisture transfer through a single-layer fabric, used as underwear for fire-fighters, at different moisture conditions. In the second stage of the study, the underwear in dry and wet state was tested together with protective clothing systems for fire-fighter consisting of three or four layers. It was found that during the evaporation of the moisture, a temperature plateau appeared during which temperatures hardly rose. The energy consumption used for the phase change of moisture located in the assembly dominated the heat transfer process as long as there was moisture present. As soon as all water had evaporated, the temperatures approached the temperatures measured for dry samples. The moisture within the clothing assembly did not lead to increased temperatures compared with the measurements with dry samples. This research has confirmed that moisture can positively affect the thermal protection of a clothing system.

Blended learning (the combination of electronic methods with traditional teaching methods) has the potential to combine the best of traditional education with the best of computer-mediated training. We chose to develop such an intervention for GP trainers who were undertaking a Continuing Medical Education (CME) course in evidence-based medicine (EBM). This study reports on our experience and investigated the factors influencing the perception on usefulness and logistics of blended learning for learners in CME. In total, 170 GP trainers participated in the intervention. We used questionnaires, observations during the four face-to-face meetings and evaluations in the e-course over one year. Additionally we organised focus groups to gain insight in some of the outcomes of the questionnaires and interpretations of the observations. The GP trainers found the design and the educational method (e-course in combination with meetings) attractive, instructive and complementary. Factors influencing their learning were (1) educational design, (2) educational method, (3) topic of the intervention, (4) time (planning), (5) time (intervention), (6) learning style, (7) technical issues, (8) preconditions and (9) level of difficulty. A close link between daily practice and the educational intervention was considered an important precondition for the success of the intervention in this group of learners. GP trainers were positive about blended learning: they found e-learning a useful way to gain knowledge and the meetings a pleasant way of transferring the knowledge into practice. Although some preconditions should be taken into consideration during its development and implementation, they would participate in similarly designed learning in the future.

Minimising the fire hazard from the use of belt conveyors in intake roadways

Energy Technology Data Exchange (ETDEWEB)

Leeming, J.R. [Health and Safety Executive, Sheffield, S. Yorkshire (United Kingdom)

2010-07-01

The fire that occurred a the Creswell underground coal mine in Derbyshire in 1950 in which 90 miners lost their lives was caused by a damaged rubber conveyor belt that ignited after being friction heated. The fire propagated along the intake trunk roadway by the burning belt itself, which ignited the timber roadway supports and hampered fire-fighting efforts. This paper demonstrated that operating conveyors in intake trunk roadways presents a risk that products of combustion can be carried to the working areas of a mine via ventilation pathways, thus creating a hazard to the underground miners. In North America, the use of belt air is not commonly used to ventilate working areas. However, these arrangements are common in the United Kingdom. As such, installation, inspection and maintenance standards have been created to minimize the risk of fire in underground, remotely operated belt conveyors in underground mines. Monitoring systems are also in place for early detection of any fire. A review of recent underground fires in the United Kingdom has shown that the measures adopted have been successful in avoiding uncontrollable fires. 13 refs., 5 figs.

A survey was conducted to assess trainee perception of the cross-cultural communication competency of U.S. military trainers and their satisfaction with the training they received. Findings from the survey show that U.S. military trainers rely significantly on local interpreters. This indicates variability in the ability of the trainers to communicate effectively with host nation partners, the variability being dependent on the capabilities of the individual interpreter. The findings illustrate the importance of providing military health personnel with training on how to work effectively with interpreters. The use of supplementary resources such as electronic translation devises when the interpreter is not capable of conveying health-related training information with the desired level of accuracy is recommended. Expanding the availability of general cultural training, which provides baseline information on local values, traditions, and customs in addition to health-specific cultural orientation, is also recommended to help military health trainers customize their training content and methods to fit the local environment.

Using MOPITT data and a Chemistry and Transport Model to Investigate Injection Height of Plumes from Boreal Forest Fires

Science.gov (United States)

Hyer, E. J.; Allen, D. J.; Kasischke, E. S.; Warner, J. X.

2003-12-01

Trace gas emissions from boreal forest fires are a significant factor in atmospheric composition and its interannual variability. A number of recent observations of emissions plumes above individual fire events (Fromm and Servranckx, 2003; COBRA 2003; Lamarque et al., 2003; Wotawa and Trainer, 2000) suggest that vertical properties of forest fire emission plumes can be very different from fossil fuel emission plumes. Understanding and constraining the vertical properties of forest fire emission plumes and their injection into the atmosphere during fire events is critical for accurate modeling of atmospheric transport and chemistry. While excellent data have been collected in a handful of experiments on individual fire events, a systematic examination of the range of behavior observed in fire events has been hampered by the scarcity of vertical profiles of atmospheric composition. In this study, we used a high-resolution model of boreal forest fire emissions (Kasischke et al, in review) as input to the Goddard/UM CTM driven by the GEOS-3 DAS, operating at 2 by 2.5 degrees with 35 vertical levels. We modeled atmospheric injection and transport of CO emissions during the fire season of 2000 (May-September). We altered the parameters of the model to simulate a range of scenarios of plume injection, and compared the resulting output to the CO profiles from the MOPITT instrument. The results presented here pertain to the boreal forest, but our methods should be useful for atmospheric modelers hoping to more realistically model transport of emission plumes from biomass burning.

To face fire it is crucial to understand its behaviour in order to maximize fighting means. To achieve this task, the development of a metrological tool is necessary for estimating both geometrical and physical parameters involved in forest fire modelling. A key parameter is to estimate fire positions accurately. In this paper an image processing tool especially dedicated to an accurate extraction of fire from an image is presented. In this work, the clustering on several colour spaces is investigated and it appears that the blue chrominance Cb from the YCbCr colour space is the most appropriate. As a consequence, a new segmentation algorithm dedicated to forest fire applications has been built using first an optimized k-means clustering in the Cb-channel and then some properties of fire pixels in the RGB colour space. Next, the performance of the proposed method is evaluated using three supervised evaluation criteria and then compared to other existing segmentation algorithms in the literature. Finally a conclusion is drawn, assessing the good behaviour of the developed algorithm. This paper is dedicated to the memory of Dr Olivier Séro-Guillaume (1950-2013), CNRS Research Director.

The Robotic Gait Rehabilitation (RGR) Trainer targets secondary gait deviations in stroke survivors undergoing rehabilitation. Using an impedance control strategy and a linear electromagnetic actuator, the device generates a force field to control pelvic obliquity through a Human-Machine Interface (i.e. a lower body exoskeleton). Herein we describe the design of the RGR Trainer Human-Machine Interface (HMI) and we demonstrate the system’s ability to alter the pattern of movement of the pelvis during gait in a healthy subject. Results are shown for experiments during which we induced hip-hiking – in healthy subjects. Our findings indicate that the RGR Trainer has the ability of affecting pelvic obliquity during gait. Furthermore, we provide preliminary evidence of short-term retention of the modified pelvic obliquity pattern induced by the RGR Trainer. PMID:22275693

The recent fighting activities in various parts of the world have highlighted the need for accurate fire source detection on one hand and fast "sensor to shooter cycle" capabilities on the other. Both needs can be met by the SPOTLITE system which dramatically enhances the capability to rapidly engage hostile fire source with a minimum of casualties to friendly force and to innocent bystanders. Modular system design enable to meet each customer specific requirements and enable excellent future growth and upgrade potential. The design and built of a fire source detection system is governed by sets of requirements issued by the operators. This can be translated into the following design criteria: I) Long range, fast and accurate fire source detection capability. II) Different threat detection and classification capability. III) Threat investigation capability. IV) Fire source data distribution capability (Location, direction, video image, voice). V) Men portability. ) In order to meet these design criteria, an optimized concept was presented and exercised for the SPOTLITE system. Three major modular components were defined: I) Electro Optical Unit -Including FLIR camera, CCD camera, Laser Range Finder and Marker II) Electronic Unit -including system computer and electronic. III) Controller Station Unit - Including the HMI of the system. This article discusses the system's components definition and optimization processes, and also show how SPOTLITE designers successfully managed to introduce excellent solutions for other system parameters.

Laparoscopic surgery requires working in a three-dimensional environment with a two-dimensional view. Skills such as depth perception, hand to eye co-ordination and bimanual manipulation are crucial to its efficacy. To compare the efficiency of training in laparoscopic skills on a VR simulator with a traditional box trainer. Twenty medical students were recruited. An initial training session on the relevant anatomy and steps of a laparoscopic cholecystectomy was given. Baseline skills were recorded using a pre-training laparoscopic cholecystectomy on the VR trainer. Parameters measured were: (1) total time taken (mins); (2) number of movements right and left instrument; (3) path length (cms) of right and left instrument was recorded. Ten students trained on a VR simulator, and ten on a box trainer, for three hours each. The box trainer group exercises were based on the Royal College of Surgeons core laparoscopic skills course, and the VR trainer exercises were based on the Simbionix LapMentor basic skills tasks. Following this both groups were reassessed by a laparoscopic cholecystectomy on the VR trainer. Both groups showed improvement in all measured parameters. A student T-test at 95% confidence interval showed no statistically significant difference between the two groups pre and post training. Both the VR and box trainer are effective in the acquisition of laparoscopic skills. Copyright © 2011 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.

McCulloch, B.

1987-01-01

The spectrum of training aids used in the nuclear industry runs the gamut from the very basic (i.e., valve training aids - gate, globe, check) to the highly complex (i.e., nuclear full scope simulator). Designing and purchasing the best training aids take much time, detailed investigation, and good understanding of plant operations. The training aid that has given the New York Power Authority the best results has been the motor operator valve (MOV) trainer. Some of the items that make the MOV trainer a good choice are: (1) large number of MOVs in the plant, (2) importance of MOVs to safe plant operation, (3) detailed MOV procedures used by the plant, (4) history of MOV problems, and (5) ability to demonstrate important concepts and operation - hammer blow effect, torque and limit switch adjustment and functions, and actual sequence of operation of the limitorque valve operator

Accurate assessment of competitive ability is a critical component of contest behavior in animals, and it could be just as important in human competition, particularly in human ancestral populations. Here, we tested the role that facial perception plays in this assessment by investigating the association between both perceived aggressiveness and perceived fighting ability in fighters' faces and their actual fighting success. Perceived aggressiveness was positively associated with the proportion of fights won, after we controlled for the effect of weight, which also independently predicted perceived aggression. In contrast, perception of fighting ability was confounded by weight, and an association between perceived fighting ability and actual fighting success was restricted to heavyweight fighters. Shape regressions revealed that aggressive-looking faces are generally wider and have a broader chin, more prominent eyebrows, and a larger nose than less aggressive-looking faces. Our results indicate that perception of aggressiveness and fighting ability might cue different aspects of success in male-male physical confrontation.

Browns Ferry nuclear power-plant fire on March 22, 1975

Scott, R.L.

1976-01-01

A review is presented of the March 22, 1975, fire at the Browns Ferry nuclear power plant. The fire originated in the electrical cable trays and burned for 7 hr before it was extinguished by water. The use of water was delayed until the reactors were in a stable shutdown condition because of the possibility of shorting circuits, which might have caused further degradation of conditions that would have been more difficult to control. However, when water was authorized, the fire was quickly extinguished. The fire-fighting efforts and the damage caused by the fire are described. The loss of electrical power and control circuits resulted in the unavailability of emergency core-cooling systems and hampered efforts to provide normal cooling to the reactor fuel. The availability of alternate cooling methods is reviewed, the efforts to maintain cooling of the reactor fuel are discussed, and the basic reasons for the common-mode failures are described. Assessments of the fire were made by three groups in the U.S. Nuclear Regulatory Commission (NRC), as well as by an independent insurance group. Some of the details of these assessments are presented, in particular, some deficiencies that the NRC Office of Inspection and Enforcement found during its investigation and some of the lessons learned from the events as determined by the NRC Special Review Group

FIGHTING ECONOMIC CRIME IN THE EUROPEAN ARENA

2010-12-01

Full Text Available The present paper tries to put together a modest study on the actions taken at EU level in order to fight economic crime. A series of measures have been implemented at national and European level to create a framework for fighting criminality. The European institutions and the national authorities are improving their cooperation in order to fight the increasing number of economic crimes committed both in the private and public sector, while Member States are approximating their legislation to the provisions of the Community acquis. We have divided these efforts into five categories corresponding to the five main areas of economic crime identified at EU level: fight against fraud, which affects the financial interests of the European Union and mainly comprises fraudulent practices in the use of EU funds and in taxation, fight against piracy and counterfeiting, public and private corruption, money laundering and organised crime. In order to combat the negative influence criminality exerts on the development of the economy and of the overall society, for each of the above mentioned areas legislative, institutional, technical and administrative measures have been adopted. We have presented these measures considering their efficiency in meeting the targets set out and the role played in their implementation by the European and national institutions.

Global vegetation-fire pattern under different land use and climate conditions

Fire is a process of global significance in the Earth System influencing vegetation dynamics, biogeochemical cycling and biophysical feedbacks. Naturally ignited wildfires have long history in the Earth System. Humans have been using fire to shape the landscape for their purposes for many millenia, sometimes influencing the status of the vegetation remarkably as for example in Mediterranean-type ecosystems. Processes and drivers describing fire danger, ignitions, fire spread and effects are relatively well-known for many fire-prone ecosystems. Modeling these has a long tradition in fire-affected regions to predict fire risk and behavior for fire-fighting purposes. On the other hand, the global vegetation community realized the importance of disturbances to be recognized in their global vegetation models with fire being globally most important and so-far best studied. First attempts to simulate fire globally considered a minimal set of drivers, whereas recent developments attempt to consider each fire process separately. The process-based fire model SPITFIRE (SPread and InTensity of FIRE) simulates these processes embedded in the LPJ DGVM. Uncertainties still arise from missing measurements for some parameters in less-studied fire regimes, or from broad PFT classifications which subsume different fire-ecological adaptations and tolerances. Some earth observation data sets as well as fire emission models help to evaluate seasonality and spatial distribution of simulated fire ignitions, area burnt and fire emissions within SPITFIRE. Deforestation fires are a major source of carbon released to the atmosphere in the tropics; in the Amazon basin it is the second-largest contributor to Brazils GHG emissions. How ongoing deforestation affects fire regimes, forest stability and biogeochemical cycling in the Amazon basin under present climate conditions will be presented. Relative importance of fire vs. climate and land use change is analyzed. Emissions resulting from

Muay Thai is a combat sport of Thailand that uses stand-up striking along with various clinching techniques. Currently, little is known about the injuries and risk factors for injuries among Muay Thai fighters. Gaining more insight into the nature and frequency of injury in this sport provides part of the overall sports injury picture, within the larger burden of injury as a public health issue. Generating this information is a critical first step toward the broader goal of improving the health and safety of Muay Thai fighters engaged in competition. This study is based upon a survey of 195 Muay Thai fighters. Participants were asked to complete a retrospective web survey on fight-related injuries. Regression analyses were conducted to determine whether injuries during sanctioned fights were related to factors such as fight experience, use of protective equipment, and injury history. Participants were aged 18 to 47 years old (median 26), predominantly male (85.9%), and white (72.3%). Respondents were professional (n = 96, 49.2%) and amateur (n = 99, 50.8%). Fighters reported a mean fight experience of 15.8 fights. Of the 195 respondents, 108 (55.4%) reported sustaining an injury during the most recent fight. The primary body region injured was the extremities (58%) versus the head, with a lower amount of self-reported concussions (5.4%). Nearly 2/3 (66.7%) of all injured fighters reported that the injury did not interfere with the bout outcome. Nearly 25% reported they missed no training time as a result of the injury. Injuries were related to professional fighter status (OR = 2.5, 95% CI = 1.4-4.5), fight experience (OR = 2.7, 95% CI = 1.5-4.9), weight class (OR = 0.923 heavy versus light, 95% CI = .86-.99), age (OR = 0.90 > 26 versus ≤26, 95% CI = .85-.95), use of protective equipment (OR = .46, 95% CI = .26-.82) and previous injury (OR = 1.81, 95% CI = .98-3.3).

The need for accurate diagnosis and appropriate return-to-play decisions following a concussion in sports has prompted the dissemination of guidelines to assist managing this condition. This study aimed to assess whether key messages within these guidelines are reflected in the knowledge of coaches and sports trainers involved in community sport. An online knowledge survey was widely promoted across Australia in May-August 2012 targeting community Australian Football (AF) and Rugby League (RL) coaches and sports trainers. 260 AF coaches, 161 AF sports trainers, 267 RL coaches and 228 RL sports trainers completed the survey. Knowledge scores were constructed from Likert scales and compared across football codes and respondent groups. General concussion knowledge did not differ across codes but sports trainers had higher levels than did coaches. There were no significant differences in either concussion symptoms or concussion management knowledge across codes or team roles. Over 90% of respondents correctly identified five of the eight key signs or symptoms of concussion. Fewer than 50% recognised the increased risk of another concussion following an initial concussion. Most incorrectly believed or were uncertain that scans typically show damage to the brain after a concussion occurs. Fewer than 25% recognised, and >40% were uncertain that younger players typically take longer to recover from concussion than adults. The key messages from published concussion management guidelines have not reached community sports coaches and sports trainers. This needs to be redressed to maximise the safety of all of those involved in community sport.

Heavy recreational visitation within protected natural areas has resulted in many ecological impacts. Many of these impacts may be avoided or minimized through adoption of low-impact hiking and camping practices. Although ?No Trace? messages have been promoted in public lands since the 1970s, few studies have documented the reception and effectiveness of these messages. The U.S. Leave No Trace Center for Outdoor Ethics develops and promotes two-day Trainer courses that teach Leave No Trace (LNT) skills and ethics to outdoor professionals, groups, and interested individuals. This study examined the change in knowledge, ethics, and behavior of LNT Trainer course participants. The respondents were a convenience sample of participants in Trainer courses offered from April through August 2003. Trainer course instructors administered pre-course and post-course questionnaires to their participants, and we contacted participants individually with a followup questionnaire 4 months after completion of their course. Scores for each of the sections increased immediately following the course, and decreased slightly over the 4 months following the course. Overall, more than half of the knowledge and behavior items, and half of the ethics items, showed significant improvement from pre-course measures to the follow-up. Age, reported LNT experience, and backpacking experience affected the participants? pre-course knowledge and behavior scores. Younger, less experienced respondents also showed a greater improvement in behavior following the course. Trainer course participants also shared their LNT skills and ethics with others both formally and informally. In summary, the LNT Trainer course was successful in increasing participants? knowledge, ethics, and behavior, which they then shared with others. Since many low impact skills taught in the LNT curriculum are supported by scientific research, LNT educational programs have the potential to effectively minimize the environmental

Full Text Available During dry season it is easily recognized that smoke will emerge at certain place both in Sumatra and Kalimantan that is in peatland. The worst situation occurred when fire burnt buried log in the logged over area where the fire fighter did not have any experience and knowledge on how to work with fire in peatland. Finally it had been found that one of the reasons why firefighter failed to fight fire in peatland is because they do not have any knowledge and experience on it. In order to know the fire behavior characteristics in different level of peat decomposition for fire management and sustainable management of the land for the community, research done in Pelalawan area, Riau Province, Indonesia, during dry season 2001. Three level of peat decomposition named Sapric, Hemic, and Fibric used. To conduct the research, two 400 m2 of plot each was established in every level of the peat decomposition. Burning done three weeks following slashing, cutting and drying at different time using circle method. During burning, flame length, rate of the spread of fire, flame temperature and following burning fuel left and the depth of peat destruction were measured. Results of research shown that in sapric site where sapric 2 has fuel load 9 ton ha-1 less than sapric 1, fire behavior was significantly different while peat destructed was deepest in sapric 2 with 31.87 cm. In hemic site where hemic 2 has fuel load 12.3 ton ha-1 more than hemic 1, fire behavior was significantly different and peat destructed deeper than hemic 1 that was 12.6 cm. In fibric site where fibric 1 has fuel load 3.5 ton ha-1 more than fibric 1, fire behavior was significantly different that has no burnt peat found. This results found that the different fuel characteristics (potency, moisture, bed depth, and type at the same level of peat decomposition will have significantly different fire behavior as it happened also on the depth of peat destruction except fibric.

Large wildfires require significant resources to combat, including dedicated meteorological support to provide accurate and timely forecasts to assist incident commanders in making decisions for logistical and tactical firefighting operations. Smaller fires often require the same capabilities for understanding fire and the fire weather environment, but access to needed resources and tools is often limited due to technical, training, or education limitations. Providing fire weather information and training to incident commanders for smaller wildfires should prove to enhance firefighting capabilities and improve safety for both firefighters and for the public as well. One of the premier tools used to support fire weather forecasting for the largest wildfires is the FX-Net product, a thin-client version of the Advanced Weather Interactive Processing System used by NWS incident meteorologists (IMETs) deployed to large wildfires. We present results from an ongoing project to extend the sophisticated products available from FX-Net to more accessible and mobile software platforms, such as Google Earth. The project involves input from IMETs and fire commanders to identify the key parameters used in fighting wildfires, and involves a large training component for fire responders to utilize simplified products to improve understanding of fire weather in the context of firefighting operations.

In the last two decades the number and intensity of fires has been significantly increased, which is unanimously associated with climate change, e.g. global warming. More extreme fires are observed, and the fire-fighting season has been expanded to June and September. The meteorological support for fire protection and planning is therefore even more important. At the Meteorological and Hydrological Service of Croatia a comprehensive monitoring and warning system has been established. It includes standard components, such as short term forecast of Fire Weather Index (FWI), but long range forecast as well. However, due to more frequent hot and dry seasons, FWI index often does not provide additional information of extremely high fire danger, since it regularly takes the highest values for long periods. Therefore the additional tools have been investigated. One of widely used meteorological products is the Haines index (HI). It provides information of potential fire growth, taking into account only the vertical instability of the atmosphere, and not the state of the fuel. Several analyses and studies carried out at the Service confirmed the correlation of high HI values with large and extreme fires. The Haines index forecast has been used at the Service for several years, employing European Centre for Medium Range Weather Forecast (ECMWF) global prediction model, as well as the limited-area Aladin model. The verification results show that these forecast are reliable, when compared to radiosonde measurements. All these results provided the introduction of the additional fire warnings, that are issued by the Service's Forecast Department.

Boxing is a sport where athletes compete in several weight categories. Professional boxers typically dehydrate to cut their weight for the weigh-in (24 h before the contest) and then rehydrate before the fight. The International Boxing Federation (IBF) mandates a second weigh-in 12 h before the fight. Our objectives were: 1) To quantify the weight gain (WG) from the 1st to the 2nd weigh-in; 2) to investigate whether rapid WG affects boxing performance (win/loss rate) and 3) whether weight discrepancy (WD) 15 between boxers exposes them to increased health risks (rate of fights ended before time limit). From official weigh-in reports of 71 IBF fights (142 fighters) the following data were gathered/calculated for each boxer: age, weight division, 1st weight, 2nd weight, WG between weigh-ins (kg and %), WD between opponents, and fight decision. Between the weigh-ins, the average WG was 2.52 ± 1.37 kg (range -0.3/6.4 kg) and 3.8 ± 2.2% of the initial body weight (range -0.4/9.3%) and the average WD 1.94 ± 1.50 kg (maximum 7.10 kg). Both WG and WD did not affect match outcomes. We observed tendencies for higher loss rate among boxers gaining more weight, and for higher victory rate in boxers with larger WD, however without reaching significance. A significant negative correlation was found between the 1st weight and the WG, both in absolute (r = -0.278, p = 0.001) and relative value (r = -0.497, p boxing performance were not found, single cases with an alarming high WG and WD were noted.

Acute toxicity tests were conducted with Hyalella azteca Saussure (an amphipod) exposed in soft and hard waters to three fire retardants (Fire-Trol GTS-R, Fire-Trol LCG-R, and Phos-Chek D75-F) and two foam suppressants (Phos-Chek WD-881 and Silv-Ex). The chemicals were slightly to moderately toxic to amphipods. The most toxic chemical to amphipods in soft and hard water was Phos-Chek WD-881 (96-h mean lethal concentration [LC50] equal to 10 mg/L and 22 mg/L, respectively), and the least toxic chemical to amphipods in soft water was Fire-Trol GTS-R (96-h LC50 equal to 127 mg/L) and in hard water was Fire-Trol LCG-R (96-h LC50 equal to 535 mg/L). Concentrations of ammonia in tests with the three fire retardants and both water types were greater than reported LC50 values and probably were the major toxic component. Estimated un-ionized ammonia concentrations near the LC50 were frequently less than the reported LC50 ammonia concentrations for amphipods. The three fire retardants were more toxic in soft water than in hard water even though ammonia and un-ionized ammonia concentrations were higher in hard water tests than in soft water tests. The accidental entry of fire-fighting chemicals into aquatic environments could adversely affect aquatic invertebrates, thereby disrupting ecosystem function.

2007-01-01

Full Text Available Rationale and Objectives: Various devices are used to aid in the education of laparoscopic skills ranging from simple box trainers to sophisticated virtual reality trainers. Virtual reality system is an advanced and effective training method, however it is yet to be adopted in India due to its cost and the advanced technology required for it. Therefore, box trainers are being used to train laparoscopic skills. Hence this study was undertaken to assess the overall effectiveness of the box-training course. Study Procedure: The study was conducted during six-day laparoscopic skills training workshops held during 2006. Twenty five surgeons; age range of 26 to 45 years, of either sex, who had not performed laparoscopic surgery before; attending the workshop were evaluated. Each participant was given a list of tasks to perform before beginning the box-training course on day one and was evaluated quantitatively by rating the successful completion of each test. Evaluation began when the subject placed the first tool into the cannula and ended with task completion. Two evaluation methods used to score the subject, including a global rating scale and a task-specific checklist. After the subject completed all sessions of the workshop, they were asked to perform the same tasks and were evaluated in the same manner. For each task completed by the subjects, the difference in the scores between the second and first runs were calculated and interpreted as an improvement as a percentage of the initial score. Statistical Analysis: Wilcoxon matched-paired signed-ranks test was applied to find out the statistical significance of the results obtained. Results: The mean percentage improvement in scores for both the tasks, using global rating scale, was 44.5% + 6.930 (Mean + SD. For task 1, using the global rating scale mean percentage improvement was 49.4% + 7.948 (Mean + SD. For task 2, mean percentage improvement using global rating scale was 39.6% + 10.4 (Mean

Xia, Jun; Tashpolat-Tiyip

2014-01-01

The dynamic monitoring of fire area is particularly important in the controlling of underground coalfield fire. This paper took the Xinjiang Shuixigou coalfield fire area as an example, through the normalized processing of the multi-temporal thermal infrared images a generalized single-channel algorithm was used to retrieval the surface temperature. Combined with the method of single band optimal density split Sec-segmentation followed by dividing the fire area into the background region, serious combust region and more serious combust region. Thermal anomaly information in the coalfield fire area and analyse the spatial and temporal dynamics change of underground coalfield were calculated as follows:(1)fire area increased 2.03 times between 1990 and 2011, the annual average degree of dynamic changes was 1.28 in the first ten years and increased to 4.57 in the last ten years;(2)the gravity of the little serious area of the coalfield fire integrally moved north to northwest from 1990 to 2001, then northeast from 2001 to 2011;(3)there were three original independent child fire area A, B and C, but A and B merged between 1990 to 2001, C also trended close A and B until 2011. Remote sensing technology provides a feasible method for the dynamic monitoring of coalfield fire area and provides theory basis and scientific guidance for the prevention of coalfield fire disaster and implementation of coalfield fires fighting engineering

Natural forest fires and controlled burning - a study of the literature

Hoernsten, L.; Nohlgren, E.; Aldentun, Y.

1995-01-01

A study of the literature was made to elucidate the history of forest fires in Sweden. Both the frequency of natural forest fires and the extent of controlled burning as a forest-management technique were examined. The literature revealed that natural forest fires occurred every 40 to 160 years, depending on the type of site and the climatic conditions. Natural forest fires are an unusual occurrence nowadays, mainly thanks to effective fire-fighting methods but also because of the reduction in the quantity of combustible materials left in the stands in modern forestry practice. The report describes the factors influencing the occurrence and frequency of forest fires and the impact these have on flora and fauna. Controlled burning has a long history of use as a method of site preparation prior to natural regeneration. Peak usage of the method occurred in the 1950s and 1960s, since when it has steadily declined. An account is given of the methods used for controlled burning. In parallel with the study, we conducted a questionnaire survey among forest enterprises to identify current interest in controlled burning. The techniques used and the costs involved are discussed. In addition to Sweden, we also looked at controlled burning in Canada, Finland and the USA. Finland is closest to Sweden when it comes to the history of controlled burning and the current interest in fire for conservation purposes. 103 refs, 18 figs

Wildfires in forests and forested areas in South Europe, North America, Central Asia and Australia are a diachronic threat with crucial ecological, economic and social impacts. Last decade the frequency, the magnitude and the intensity of fires have increased even more because of the climate change. An efficient response to such disasters requires an effective planning, with an early detection system of the ignition area and an accurate prediction of fire propagation to support the rapid response mechanisms. For this reason, information systems able to predict and visualize the behavior of fires, are valuable tools for fire fighting. Such systems, able also to perform simulations that evaluate the fire development scenarios, based on weather conditions, become valuable Decision Support Tools for fire mitigation planning. A Web-based Information System (WIS) developed in the framework of the FLIRE (Floods and fire risk assessment and management) project, a LIFE+ co-funded by the European Commission research, is presented in this study. The FLIRE WIS use forest fuel maps which have been developed by using generalized fuel maps, satellite data and in-situ observations. Furthermore, it leverages data from meteorological stations and weather forecast from numerical models to feed the fire propagation model with the necessary for the simulations inputs and to visualize the model's results for user defined time periods and steps. The user has real-time access to FLIRE WIS via any web browser from any platform (PC, Laptop, Tablet, Smartphone).

The Current State of Personal Training: an Industry Perspective of Personal Trainers in a Small Southeast Community

Science.gov (United States)

Melton, Deana I.; Katula, Jeffrey A.; Mustian, Karen M.

2014-01-01

Although research has identified a number of qualities and competencies necessary to be an effective exercise leader, the fitness industry itself is largely unregulated and lacks a unified governing body. As such, a plethora of personal trainer certifications exists with varying degrees of validity that fail to ensure qualified trainers and, therefore, protect the consumer. It is argued that the potential consequences of this lack of regulation are poor societal exercise adherence, potential injury to the client, and poor public perception of personal trainers. Additionally, it is not known whether personal trainers are meeting the needs of their clients or what criteria are used in the hiring of personal trainers. Thus, the purpose of this investigation was to examine the current state of personal training in a midsized Southeast city by using focus group methodology. Local personal trainers were recruited for the focus groups (n = 11), and the results from which were transcribed, coded, and analyzed for themes using inductive reasoning by the authors. Qualities and characteristics that identified by participants clustered around 4 main themes. Client selection rationale consisted of qualities that influenced a client’s decision to hire a particular trainer (e.g., physique, gender, race). Client loyalty referred to the particular qualities involved in maintaining clients (e.g., motivation skills, empathy, social skills). Credentials referred to formal training (e.g., college education, certifications). Negative characteristics referred to qualities considered unethical or unprofessional (e.g., sexual comments, misuse of power) as well as the consequences of those behaviors (e.g., loss of clients, potential for litigation). These results are discussed regarding the implications concerning college programs, certification organizations, increasing public awareness of expectations of qualified trainers, and a move towards state licensure.

There are differences between the genders in their innate performances on simulation trainers, which may impair accurate assessment of psychomotor skills. The performance of fourth-year students with no exposure to the Minimally Invasive Surgical Trainer compared based on gender, and other psychomotor skills. Our study included 16 male and 16 female students. After adjusting for choice of medical specialty (Pvideo game use (P=.6), and experience in the operating room (P=.4), female sex was an independent factor for worse performance (P=.04) in multivariate models. Women took more time than men (P<.01) and made more errors (29 versus 25 on 3 reps, P<.01). Among medical students with no previous exposure to laparoscopic trainers, female students perform worse than male students after adjusting for confounding factors. This difference must be recognized by training programs while using simulators for training and evaluation.

[Development of a gait trainer with regulated servo-drive for rehabilitation of locomotor disabled patients].

Uhlenbrock, D; Sarkodie-Gyan, T; Reiter, F; Konrad, M; Hesse, S

1997-01-01

The aim of the present study was to develop a new gait trainer for the rehabilitation of non-ambulatory patients. For the simulation of the gait phase, we used a commercially available fitness trainer (Fast Track) with two foot plates moving in an alternating fashion and connected to a servo-controlled propulsion system providing the necessary support for the movement depending on the patient's impairment level. To compensate deficient equilibrium reflexes, the patient was suspended in a harness capable of supporting some of his/her weight. Video analysis of gait and the kinesiological EMG were used to assess the pattern of movement and the corresponding muscle activity, which were then evaluated in healthy subjects, spinal cord injured and stroke patients and compared with walking on the flat or on a treadmill. Walking on the gait trainer was characterised by a symmetrical, sinusoidal movement of lower amplitude than in normal gait. The EMG showed a low activity of the tibialis anterior muscle, while the antigravity muscles were clearly activated by the gait trainer during the stance phase. In summary, the new gait trainer generates a symmetrical gait-like movement, promoting weight acceptance in the stance phase, which is important for the restoration of walking ability.

Regional variation in fire weather controls the reported occurrence of Scottish wildfires

Full Text Available Fire is widely used as a traditional habitat management tool in Scotland, but wildfires pose a significant and growing threat. The financial costs of fighting wildfires are significant and severe wildfires can have substantial environmental impacts. Due to the intermittent occurrence of severe fire seasons, Scotland, and the UK as a whole, remain somewhat unprepared. Scotland currently lacks any form of Fire Danger Rating system that could inform managers and the Fire and Rescue Services (FRS of periods when there is a risk of increased of fire activity. We aimed evaluate the potential to use outputs from the Canadian Fire Weather Index system (FWI system to forecast periods of increased fire risk and the potential for ignitions to turn into large wildfires. We collated four and a half years of wildfire data from the Scottish FRS and examined patterns in wildfire occurrence within different regions, seasons, between urban and rural locations and according to FWI system outputs. We used a variety of techniques, including Mahalanobis distances, percentile analysis and Thiel-Sen regression, to scope the best performing FWI system codes and indices. Logistic regression showed significant differences in fire activity between regions, seasons and between urban and rural locations. The Fine Fuel Moisture Code and the Initial Spread Index did a tolerable job of modelling the probability of fire occurrence but further research on fuel moisture dynamics may provide substantial improvements. Overall our results suggest it would be prudent to ready resources and avoid managed burning when FFMC > 75 and/or ISI > 2.

Nacht, S.

1999-01-01

The Mercury Fire Training Pit is a former fire training area located in Area 23 of the Nevada Test Site (NTS). The Mercury Fire Training Pit was used from approximately 1965 to the early 1990s to train fire-fighting personnel at the NTS, and encompasses an area approximately 107 meters (m) (350 feet [ft]) by 137 m (450 ft). The Mercury Fire Training Pit formerly included a bermed burn pit with four small burn tanks, four large above ground storage tanks an overturned bus, a telephone pole storage area, and areas for burning sheds, pallets, and cables. Closure activities will include excavation of the impacted soil in the aboveground storage tank and burn pit areas to a depth of 1.5 m (5 ft), and excavation of the impacted surface soil downgradient of the former ASTs and burnpit areas to a depth of 0.3 m (1 ft). Excavated soil will be disposed in the Area 6 Hydrocarbon Landfill at the NTS

Simulating wildfire spread behavior between two NASA Active Fire data timeframes

2017-12-01

Although NASA's Active Fire dataset is considered valuable in mapping the spatial distribution and extent of wildfires across the world, the data is only available at approximately 12-hour time intervals, creating uncertainties and risks associated with fire spread and behavior between the two Visible Infrared Imaging Radiometer Satellite (VIIRS) data collection timeframes. Our study seeks to close the information gap for the United States by using the latest Active Fire data collected for instance around 0130 hours as an ignition source and critical inputs to a wildfire model by uniquely incorporating forecasted and real-time weather conditions for predicting fire perimeter at the next 12 hour reporting time (i.e. around 1330 hours). The model ingests highly dynamic variables such as fuel moisture, temperature, relative humidity, wind among others, and prompts a Monte Carlo simulation exercise that uses a varying range of possible values for evaluating all possible wildfire behaviors. The Monte Carlo simulation implemented in this model provides a measure of the relative wildfire risk levels at various locations based on the number of times those sites are intersected by simulated fire perimeters. Model calibration is achieved using data at next reporting time (i.e. after 12 hours) to enhance the predictive quality at further time steps. While initial results indicate that the calibrated model can predict the overall geometry and direction of wildland fire spread, the model seems to over-predict the sizes of most fire perimeters possibly due to unaccounted fire suppression activities. Nonetheless, the results of this study show great promise in aiding wildland fire tracking, fighting and risk management.

To construct an advanced mechanized gait trainer to enable patients the repetitive practice of a gaitlike movement without overstraining therapists. DEVICE: Prototype gait trainer that simulates the phases of gait (by generating a ratio of 40% to 60% between swing and stance phases), supports the subjects according to their ability (lifts the foot during swing phase), and controls the center of mass in the vertical and horizontal directions. Two nonambulatory, hemiparetic patients who regained their walking ability after 4 weeks of daily training on the gait trainer, a 55-year-old woman and a 62-year-old man, both of whom had a first-time ischemic stroke. Four weeks of training, five times a week, each session 20 minutes long. Functional ambulation category (FAC, levels 0-5) to assess gait ability and ground level walking velocity. Rivermead motor assessment score (RMAS, 0-13) to assess gross motor function. Patient 1: At the end of treatment, she was able to walk independently on level ground with use of a walking stick. Her walking velocity had improved from .29m/sec to .59m/sec. Her RMAS score increased from 4 to 10, meaning she could walk at least 40 meters outside, pick up objects from floor, and climb stairs independently. Patient 2: At end of 4-week training, he could walk independently on even surfaces (FAC level 4), using an ankle-foot orthosis and a walking stick. His walking velocity improved from .14m/sec to .63m/sec. His RMAS increased from 3 to 10. The gait trainer enabled severely affected patients the repetitive practice of a gaitlike movement. Future studies may elucidate its value in gait rehabilitation of nonambulatory subjects.

  An organizational climate is largely based on an employee's perceptions of the working conditions in which he or she engages regularly. A multifaceted concept, the organizational climate is often formed by perceptions of employee welfare, rewards, and support. Achieving work-life balance is also a part of the climate.   To learn collegiate athletic trainers' perceptions of organizational climate and specifically how it may pertain to their work-life balance.   Phenomenologic study.   Collegiate practice setting.   Thirty athletic trainers working in the collegiate athletics setting took part in 1-on-1 phone interviews. The participants were 30.5 (interquartile range [IQR] = 7.75) years old and had been certified for 7 (IQR = 5) years and at their current position for 4 (IQR = 3) years.   Participants completed a phone interview that followed a semistructured framework. All transcribed interviews were analyzed using a phenomenologic approach. Researcher triangulation, expert review, and data saturation were used to establish credibility.   Athletic trainers working in the collegiate athletics setting who had positive perceptions of their work-life balance described their organizational climate as family friendly. Our participants' supervisors allowed for autonomy related to work scheduling, which provided opportunities for work-life balance. These athletic trainers believed that they worked in a climate that was collegial, which was helpful for work-life balance. In addition, the importance of placing family first was part of the climate.   The perceptions of our participants revealed a climate of family friendliness, supervisor support, and collegiality among staff members, which facilitated the positive climate for work-life balance. The mindset embraced the importance of family and recognized that work did not always have to supersede personal priorities.

The laparoscopic minimally invasive surgical technique is widely employed on a global scale. However, the efficient and ethical teaching of this technique requires equipment for surgical simulation. These educational devices are present on the market in the form of box trainers and virtual reality simulators, or some combination of those. In this article, we present a systematic overview of commercially available surgical simulators describing the most important features of each product. Our overview elaborates on box trainers and virtual reality simulators, and also touches on surgical robotics simulators, together with operating room workflow simulators, for the sake of completeness. Apart from presenting educational tools, we evaluated the literature of laparoscopic surgical education and simulation, to provide a complete picture of the unfolding trends in this field.

Full Text Available Considering the complexity of judo and the ample energy and neuromuscular demands, a whole process of competitive preparation must be directed to different physical capacities allowing the athlete to perform his combat actions with the best suitability possible. Mapping the  behaviour of a judo athlete from observations of behaviour units  in a real fighting situation would be a way of trying to identify the best topography or the best "aptitude" to achieve victory. The present investigation analysed the judo from the interactions of a real competition situation, aiming to verify, between winners and losers, possible differences or correlations between anthropometric parameters, motor performance and functional behaviours in a competitive situation. The results showed that: a the experience is decisive between winning or losing; b leg techniques are the most used between winners and losers, and losers use them more frequently; c there are different strategies between fights; d The energy cost in judo depends on the configuration of the fights. It is believed that such results can help coaches and athletes in guiding and rationalizing the training process in relation to performance determinants in judo.

Examining the Experiences of Athletic Trainers as they transition into their First Full-Time Position

Full Text Available Transition to clinical practice is an important topic in athletic training, as it can be a period of time that presents challenges for the athletic trainer. Most of the research pertaining to transition to practice focuses on the skills and knowledge necessary for clinical practice, yet we know that stress can manifest from not only being an independent practitioner but also from learning how to balance one’s roles. We wanted to understand the perspective of today’s novice athletic trainers and how they feel in their first full-time position, specifically relating to their professional development and establishment or maintenance of work-life balance (WLB. Using a qualitative paradigm, we phone interviewed athletic trainers who were categorized as career starters by the National Athletic Trainers’ Association. Using a purposive recruitment strategy we were able to recruit 20 (12 female, 8 male athletic trainers meeting this classification. General inductive analyses were used to code the data from our interviews, and we satisfied credibility though saturation of the data, peer review, and researcher triangulations during the coding process. Our findings suggest that while confidence in clinical skills is apparent, some of the more administrative aspects of clinical practice present challenges. We found that various employment settings offered various expectations or challenges that had the potential to impact WLB. A blend of professional and organizational processes helped transition the athletic trainer, and although both were helpful each also could be bolstered to improve transitioning for the newly credentialed athletic trainer. Employers of early career starters should be aware of the stress related to transition to practice, and the time it can take to acclimate.

Imaging of Nuclear Weapon Trainers

2017-12-06

The Configurable Muon Tracker (CMT) is an adaptation of the existing drift tube detector commercially available from Decision Sciences International Corporation (DSIC). NSTec engineered the CMT around commercially available drift tube assemblies to make a detector that is more versatile than previous drift tube assemblies. The CMT became operational in February 2013. Traditionally, cosmic-ray muon trackers rely on near-vertical trajectory muons for imaging. Since there are scenarios where imaging using vertical trajectory muons is not practical, NSTec designed the CMT specifically for quick configurability to track muons from any trajectory. The CMT was originally designed to be changed from vertical imaging mode to horizontal imaging mode in a few hours with access to a crane or other lifting equipment. In FY14, locations for imaging weapon trainers and SNM were identified and it was determined that lifting equipment would not typically be available in experimental areas. The CMT was further modified and a portable lifting system was developed to allow reconfiguration of the CMT without access to lifting equipment at the facility. This system was first deployed at Los Alamos National Laboratory’s W-division, where several trainers were imaged in both horizontal and vertical modes. Real-time images have been compared in both modes showing that imaging can be done in both modes with the expected longer integration time for horizontal mode. Further imaging and post processing of the data is expected to continue into early FY15.

Structural adaptations to diverse fighting styles in sexually selected weapons.

McCullough, Erin L; Tobalske, Bret W; Emlen, Douglas J

2014-10-07

The shapes of sexually selected weapons differ widely among species, but the drivers of this diversity remain poorly understood. Existing explanations suggest weapon shapes reflect structural adaptations to different fighting styles, yet explicit tests of this hypothesis are lacking. We constructed finite element models of the horns of different rhinoceros beetle species to test whether functional specializations for increased performance under species-specific fighting styles could have contributed to the diversification of weapon form. We find that horns are both stronger and stiffer in response to species-typical fighting loads and that they perform more poorly under atypical fighting loads, which suggests weapons are structurally adapted to meet the functional demands of fighting. Our research establishes a critical link between weapon form and function, revealing one way male-male competition can drive the diversification of animal weapons.

Were selected on the Internet several championship of kumite of the JKA and of the ITKF. The study detected a high probability of point in the zone 7 and in the zone 2. The study determined that the most points at the corner occurred when the karateka practiced the attack in fight zone. Kruskal-Wallis ANOVA verified significant difference between the fight zone with points, H (10 = 29,49, p = 0,001. The Mann Whitney U test detected significant difference between the zone 5 with waza-ari versus all the zone. The greatest number of points in the fight zone was in agreement with the size of the fight zone. The central zone or zone 5 has 6x6 m, during the female kumite occurred more points, total of 68 waza-aris and 5 ippons. The study on the fight zone with points of the female kumite permits that the karateka has knowledge about the combat zones and guides the karateka before, during and after the female kumite. However, more studies should be done to confirm these findings.

Spontaneous and industrially caused subsurface coal fires are worldwide disasters that destroy coal resources, cause air pollution and emit a large amount of green house gases. Especially in developing countries, such as China, India and Malaysia, this problem has intensified over the last 15 years. In China alone, 10 to 20 million tons of coal are believed to be lost in uncontrolled coal fires. The cooperation of developing countries and industrialized countries is needed to enforce internationally concerted approaches and political attention towards the problem. The Clean Development Mechanism (CDM) under the framework of the Kyoto Protocol may provide an international stage for financial investment needed to fight the disastrous situation. A Sino-German research project for coal fire exploration, monitoring and extinction applied several geophysical approaches in order to estimate the annual baseline especially of CO2 emissions from near subsurface coal fires. As a result of this project, we present verifiable methodologies that may be used in the CDM framework to estimate the amount of CO2 emissions from near subsurface coal fires. We developed three possibilities to approach the estimation based on (1) thermal energy release, (2) geological and geometrical determinations as well as (3) direct gas measurement. The studies involve the investigation of the physical property changes of the coal seam and bedrock during different burning stages of a underground coal fire. Various geophysical monitoring methods were applied from near surface to determine the coal volume, fire propagation, temperature anomalies, etc.

2011-01-01

Much work in behavioral ecology has shown that animals fight over resources such as food, and that they make strategic decisions about when to engage in such fights. Here, we examine the evolution of one, heretofore unexamined, component of that strategic decision about whether to fight for a resource. We present the results of a computer simulation that examined the evolution of over- or underestimating the value of a resource (food) as a function of an individual's current hunger level. In ...

Seismic Fragility of the LANL Fire Water Distribution System

2007-03-30

The purpose of this report is to present the results of a site-wide system fragility assessment. This assessment focuses solely on the performance of the water distribution systems that supply Chemical and Metallurgy Research (CMR), Weapons Engineering and Tritium Facility (WETF), Radioactive Liquid Waste Treatment Facility (RLWTF), Waste Characterization, Reduction, Repackaging Facility (WCRRF), and Transuranic Waste Inspectable Storage Project (TWISP). The analysis methodology is based on the American Lifelines Alliance seismic fragility formulations for water systems. System fragilities are convolved with the 1995 LANL seismic hazards to develop failure frequencies. Acceptance is determined by comparing the failure frequencies to the DOE-1020 Performance Goals. This study concludes that: (1) If a significant number of existing isolation valves in the water distribution system are closed to dedicate the entire water system to fighting fires in specific nuclear facilities; (2) Then, the water distribution systems for WETF, RLWTF, WCRRF, and TWISP meet the PC-2 performance goal and the water distribution system for CMR is capable of surviving a 0.06g earthquake. A parametric study of the WETF water distribution system demonstrates that: (1) If a significant number of valves in the water distribution system are NOT closed to dedicate the entire water system to fighting fires in WETF; (2) Then, the water distribution system for WETF has an annual probability of failure on the order of 4 x 10{sup -3} that does not meet the PC-2 performance goal. Similar conclusions are expected for CMR, RLWTF, WCRRF, and TWISP. It is important to note that some of the assumptions made in deriving the results should be verified by personnel in the safety-basis office and may need to be incorporated in technical surveillance requirements in the existing authorization basis documentation if credit for availability of fire protection water is taken at the PC-2 level earthquake levels

Schwartz, Joseph A; Beaver, Kevin M

2013-10-01

Fighting-related injuries are common among adolescents within the United States, but how such injuries relate to subsequent cognitive functioning remains unclear. In particular, the long-term effect of fighting-related injuries suffered during important developmental periods, such as adolescence, on subsequent cognitive functioning has been overlooked by previous studies. The purpose of this study is to examine the association between sustaining serious fighting-related injuries and changes in verbal intelligence (IQ) over a 5- to 6-year time period. Longitudinal multivariate statistical models were used to analyze data from the National Longitudinal Study of Adolescent Health collected between 1994 and 2002 and analyzed in 2013. Even a single fighting-related injury resulted in a significant reduction in IQ over time even after controlling for age, race, sex, and changes in socioeconomic status (SES) over the study period. Additionally, females experienced a significantly greater reduction in IQ from each fighting-related injury than males. Fighting-related injuries have a significant impact on subsequent cognitive functioning and intelligence. The implications for future policies and research are discussed in more detail.

THE CONTRIBUTION OF PLAY FIGHTING TO THE EMOTIONAL DEVELOPMENT OF CHILDREN

Directory of Open Access Journals (Sweden)

Ioan TRIFA

2016-11-01

Full Text Available Play fighting is a form of behavior in which partners compete with each other to gain an advantage. Behavior during play fighting largely resembles the behavior in a real fight, where partners encounter, push and pull down onto the ground, trying to get into a position whereby to control or to dominate the opponent. In the play, unlike the fight, movements are exaggerated and performed at a lower intensity, muscles being somewhat less tensed, and certain actions that can cause injury to the partner are inhibited or modified, while offensive-defensive roles will be reversed quite frequently. Play fighting can be considered a type of evolutionary adaptation designed to facilitate those experiences that will shape the cognitive and emotional development necessary for living in social communities. Research undertaken on different mammal species shows that play fighting offers many opportunities for expression and decoding emotions, improves emotional regulation and contributes to the development of coping mechanisms.

Full Text Available The purpose of this study was to examine heart rate (HR and blood lactate (LA concentration before, during and after a competitive Tae kwon do (TKD fight performed by elite women performers. Specifically, we were interested to see weather HR and LA responses to competitive fight were greater than to TKD or karate exercises published in scientific literature. Seven international-standard women TKD fighters participated in the study. HR was recorded continuously throughout the fight using Polar Vantage telemetric HR monitors. LA samples were taken before and 3 min after the fight and analysed using an Accusport portable lactate analyzer. At the beginning of the fight, HR significantly increased (p<0.01 from pre-fight values of 91.6±9.9 beats min-1 to 144.1±13.6 beats min-1. During the whole fight the HRmean was 186.6±2.5 beats min-1 and remained significantly elevated (p<0.01 at 3 min into recovery. HR values expressed as a percentage of HRmax averaged during the whole fight at 91.7±2.6% respectively. LA concentration significantly increased (p<0.01 3 min after the fight and averaged 82% of LApeak values measured after the VO2max test. Results of the present study indicate that physiological demands of competitive TKD fight in women, measured by HR and LA responses, are considerably higher than the physiological demands of TKD or karate training exercises. The observed HR and LA responses suggest to us that conditioning for TKD should generally emphasise high-intensity anaerobic exercise.

Full Text Available Abstract Background Leisure-time physical activity and strength training participation levels are low and socioeconomically distributed. Fitness trainers (e.g. gym/group instructors may have a role in increasing these participation levels. However, it is not known whether the training location and characteristics of Australian fitness trainers vary between areas that differ in socioeconomic status. Methods In 2014, a sample of 1,189 Australian trainers completed an online survey with questions about personal and fitness industry-related characteristics (e.g. qualifications, setting, and experience and postcode of their usual training location. The Australian Bureau of Statistics ‘Index of Relative Socioeconomic Disadvantage’ (IRSD was matched to training location and used to assess where fitness professionals trained and whether their experience, qualification level and delivery methods differed by area-level disadvantage. Linear regression analysis was used to examine the relationship between IRSD score and selected characteristics adjusting for covariates (e.g. sex, age. Results Overall, 47 % of respondents worked in areas within the three least-disadvantaged deciles. In contrast, only 14.8 % worked in the three most-disadvantaged deciles.

Wang, F C; Yu, C H; Chou, T Y

2009-08-01

This paper applies robust algorithms to control an active gait trainer for children with walking disabilities. Compared with traditional rehabilitation procedures, in which two or three trainers are required to assist the patient, a motor-driven mechanism was constructed to improve the efficiency of the procedures. First, a six-bar mechanism was designed and constructed to mimic the trajectory of children's ankles in walking. Second, system identification techniques were applied to obtain system transfer functions at different operating points by experiments. Third, robust control algorithms were used to design Hinfinity robust controllers for the system. Finally, the designed controllers were implemented to verify experimentally the system performance. From the results, the proposed robust control strategies are shown to be effective.

Fighting terrorism in Africa: Benchmarking policy harmonization

Asongu, Simplice A.; Tchamyou, Vanessa S.; Minkoua N., Jules R.; Asongu, Ndemaze; Tchamyou, Nina P.

2018-02-01

This study assesses the feasibility of policy harmonization in the fight against terrorism in 53 African countries with data for the period 1980-2012. Four terrorism variables are used, namely: domestic, transnational, unclear and total terrorism dynamics. The empirical evidence is based on absolute beta catch-up and sigma convergence estimation techniques. There is substantial absence of catch-up. The lowest rate of convergence in terrorism is in landlocked countries for regressions pertaining to unclear terrorism (3.43% per annum for 174.9 years) while the highest rate of convergence is in upper-middle-income countries in domestic terrorism regressions (15.33% per annum for 39.13 years). After comparing results from the two estimation techniques, it is apparent that in the contemporary era, countries with low levels of terrorism are not catching-up their counterparts with high levels of terrorism. As a policy implication, whereas some common policies may be feasibly adopted for the fight against terrorism, the findings based on the last periodic phase (2004-2012) are indicative that country-specific policies would better pay-off in the fight against terrorism than blanket common policies. Some suggestions of measures in fighting transnational terrorism have been discussed in the light of an anticipated surge in cross-national terrorism incidences in the coming years.

A train-the-trainer education and promotion program: chronic fatigue syndrome – a diagnostic and management challenge

2008-10-01

Full Text Available Abstract Background Chronic fatigue syndrome (CFS is a complicated illness for providers and patients. Fewer than 20% of persons with CFS have been diagnosed and treated. For providers, compounding the issue are the challenges in making a diagnosis due to the lack of a biomedical marker. Methods The objective of the CFS diagnosis and management curriculum was to instruct core trainers as to the evaluation, diagnosis, and management of CFS. Over a two year period, 79 primary care physicians, physician assistants, and nurse practitioners from diverse regions in the U.S. participated as core trainers in a two day Train-the-Trainer (TTT workshop. As core trainers, the workshop participants were expected to show increases in knowledge, self-efficacy, and management skills with the primary goal of conducting secondary presentations. Results The optimal goal for each core trainer to present secondary training to 50 persons in the health care field was not reached. However, the combined core trainer group successfully reached 2064 primary care providers. Eighty-two percent of core trainers responded "Very good" or "Excellent" in a post-tessurvey of self-efficacy expectation and CFS diagnosis. Data from the Chicago workshops showed significant improvement on the Primary Care Opinion Survey (p Conclusion Data show the workshop was successful in meeting the objectives of increasing CFS knowledge and raising perceived self-efficacy towards making a diagnosis. The CFS TTT program informed an educational provider project by shifting the format for physicians to grand rounds and continuing medical education design while retaining TTT aspects for nurse practitioners and physicians assistants. Evaluations also indicate that secondary trainings may be more readily employed and accepted if administrative barriers are addressed early in the planning phases.

tight silo, as any holes or leaks will feed the pyrolysis with oxygen, and could further result in losses of the extinguishing gas. A silo should thus be designed with the means to close the silo air tight during extinguishment of a fire. The efficiency of the extinction could be further enhanced by application of low or medium expansion fire fighting foam on top of the stored material in the silo. It could further be appropriate to inject inert gas in the void top space of the silo in an early stage of the fire fighting in order to reduce the risk for gas/dust explosion. Generally, emptying of the silo should not be initiated before the fire is appropriately suppressed, i.e. not before the pyrolysis activity (temperature) has been considerably reduced. An inert atmosphere should further be maintained in the silo during the entire period while emptying the silo. Water should not be used as an extinguishing media, as water could result in considerably expansion (swelling) of the porous material in the silo. This could both damage the silo construction and make the stored material to stick on the silo walls.

Full Text Available International terrorism, a phenomenon with constant development, is today acertainty and has dramatically marked the beginning of this century and millennium. Thisproblem has reached a global dimension and it represents a concern to the entire internationalcommunity. Over the time, numerous international and regional regulations have been framed, inorder to prevent and combat terrorism. The European Union condemns terrorist acts andrecognizes the central role of the United Nations, in fighting against terrorism and promotingsecurity, as well as the contribution of the new NATO in what concerns the defense and securitypromotion. Europe has to act more firmly in order to consolidate the defense against terrorismand the European Union’s borders. At the same time, the European Union considers that only aconcerted and firm action from all the states and the major actors on the international scenewould lead to the identification of the solutions which can contribute to the efficient fight againstterrorism and, by these means, provide for the international peace and security. The proportion ofthe danger terrorism represents has turned the fight against this phenomenon in an internationalcommunity’s desideratum.

Trainer-to-student ratios for teaching psychomotor skills in health care fields, as applied to osteopathic manipulative medicine.

Science.gov (United States)

Snider, Karen T; Seffinger, Michael A; Ferrill, Heather P; Gish, Eric E

2012-04-01

The hallmark of osteopathic medical education is the inclusion of hands-on instruction in osteopathic manipulative medicine (OMM), which includes palpatory diagnosis and osteopathic manipulative treatment (OMT). This OMM training typically involves a primary instructor presenting theory and techniques with step-by-step demonstrations to a large group of first- and second-year osteopathic medical students. Additional instructors, referred to as table trainers, assist the primary instructor by supervising the students as they practice the presented techniques. To the authors' knowledge, there is no currently accepted standard for a table trainer-to-student ratio in OMM skills laboratories within osteopathic medical schools in the United States. However, through a Google Web search and PubMed literature review, the authors identified published trainer-to-student ratios used in other health care skills training curricula. Psychomotor skills training courses in health care fields typically have a table trainer-to-student ratio of 1 trainer to 8 or fewer students. On the basis of these findings and psychomotor skills learning theory, the authors conclude that this ratio is likely sufficient for OMM skills training.

Full Text Available The aim of this study was to investigate the neuromuscular performance responses following successive Brazilian Jiu-Jitsu (BJJ fights. Twenty-three BJJ athletes (age: 26.3 ± 6.3 years; body mass: 79.4 ± 9.7 kg; body height: 1.80 ± 0.1 m undertook 3 simulated BJJ fights (10 min duration each separated by 15 min of rest. Neuromuscular performance was measured by the bench press throw (BPT and vertical counter movement jump (VCMJ tests, assessed before the 1st fight (Pre and after the last one (Post. Blood lactate (LA was measured at Pre, 1 min Post, and 15 min Post fights. Paired t-tests were employed in order to compare the BPT and VCMJ results. One-way ANOVA with Bonferroni post hoc tests were utilized to compare LA responses. The results revealed a significant (p < 0.05 increase in VCMJ performance (40.8 ± 5.5 cm Pre vs. 42.0 ± 5.8 cm Post, but no significant changes in the BPT (814 ± 167 W Pre vs. 835 ± 213 W Post were observed. LA concentration increased significantly (p < 0.05 at Post, both in the 1st min and the 15th min of recovery. We concluded that successive simulated BJJ fights demanded considerable anaerobic contribution of ATP supply, reinforcing the high-intensity intermittent nature of the sport. Nevertheless, no negative impact on acute neuromuscular performance (power was observed.

Training the Trainers of Tomorrow Today (T4) is a new way to deliver “Training for Trainers”. Responding to local dissatisfaction with existing arrangements, T4 builds on 3 essential requirements for a future shape of training: 1. Clinical Leadership and a Collaborative Approach 2. Cross-Specialty Design and Participation 3. Local Delivery and Governance Networks Design principles also included: 3 levels of training to reflect differing needs of clinical supervisors, educational supervisors and medical education leader, mapping to GMC requirements and the London Deanery's Professional Development Framework; alignment of service, educational theory and research; recognition of challenges in delivering and ensuring attendance in busy acute and mental health settings, and the development of a faculty network. The delivery plan took into account census of professional development uptake and GMC Trainee Surveys. Strong engagement and uptake from the 11 Trusts in NW London has been achieved, with powerful penetration into all specialties. Attendance has exceeded expectations. Against an initial 12 month target of 350 attendances, 693 were achieved in the first 8 months. Evaluation of content demonstrates modules are pitched appropriately to attendees needs, with positive feedback from trainers new to the role. Delivery style has attracted high ratings of satisfaction: 87% attendees rating delivery as “good\\excellent”. External evaluation of impact demonstrated improved training experiences through changes in supervision, the learning environment and understanding of learning styles. We have addressed sustainability of the programme by advertising and recruiting Local Faculty Development Trainers. Volunteer consultants and higher trainees are trained to deliver the programme on a cascade model, supported by the Specialty Tutors, individual coaching and educational bursaries. The Trainers are local champions for excellence in training, provide a communication

1993-01-01

The purpose of this study was to document the utilization of performance evaluation instruments by technical trainers in the evaluation of maintenance personnel in US nuclear power plants. Performance evaluation of maintenance personnel has been identified by nuclear utilities and the Nuclear Regulatory Commission as the only acceptable method of determining worker competence. The NRC requires performance evaluation to be conducted to performance standards, but it does not specify the standards or the method to be utilized. Each plant is free to establish its own standards and methods of evaluation. This was a descriptive study utilizing descriptive statistics for the analysis of the data. The subjects included 655 maintenance trainers in 72 US nuclear plants. Conclusions of the study include: (1) Technical trainers are in compliance with NRC regulations. (2) Evaluation materials developed by the Institute of Nuclear Power Operations are used by technical trainers in every one of the 62 plants that responded. (3) In-plant or self-developed Performance Evaluation Instruments are utilized by 419 or 95.2% of the technical trainers. (4) Technical trainers incorporate nine common components into their Performance Evaluation Instruments. (5) Technical trainers evaluate maintenance processes and the product produced by workers when following procedures and specifications are critical and when safety hazards are involved. (6) Technical trainers believe that utilizing Performance Evaluation Instruments makes their job easier by providing documentation about the quality and standards of maintenance skills. (7) Technical trainers believe that maintenance workers benefit when their skills are assessed through the use of Performance Evaluation Instruments

OECD countries. The contents of each chapter are based on the writers' knowledge on his or her national practices and on the results of the questionnaire. The emphasis in the descriptions of the national practices also reflects the information supplied by the responding countries. Fire PSA is also used in other OECD countries, but the scope of this report is limited to those countries which responded to the questionnaire. The contents of this report are as follows: Fire PSA methodology overview - Based on a review of fire risk studies performed in the contributing countries, the report addresses different methodology and applications issues. Methodology issues, treated in Chapter 2, include the treatment of physical barriers, fire detection and suppression systems and fire fighting. They also include the treatment of operator actions and dependencies (both direct and indirect) between a fire and the plant's safety systems, definition of initiating events, and screening methods. Key assumptions and the effect of plant operational state (i.e., full power vs. low power operation) are dealt with in the report as well. Fire simulation models and codes applied or available - Chapter 3 of the report identifies which fire simulation codes have been used in actual PSAs. The models and scenarios used in different codes are described. To build confidence on fire simulation models, validation against experimental results in different types of fires is necessary. Fire experiments and the pre- and post experiment calculation used for code validation as well as ongoing fire simulation code development projects are discussed. Examples of fire scenarios and typical modeling assumptions are treated and numerous references are given in Chapter 3. References for experimental case studies and related simulation models and codes used for analyzing the production and spreading of smoke are also provided.

Mamaqi, Xhevrie; Rubio, Pilar Olave; Alvarez, Jesús Miguel

The workplace of today is characterized by rapid changes in work processes, in competition, in customer demands, and in work practices. To keep abreast of these rapid changes employers and employees must be committed to lifelong learning in order to keep ahead. One of the most important actors in the lifelong learning development process are the trainers, whose professional characteristics needs meeting new skills and adapting an varied and specific contents of the current labour market. Affected by the discontinuity and a high rate of job rotation, the recognition of it labour status and basic competence and skills, forms part of the Bologna Process recognized as Vocational Education Training (VET). Sixty in-depth interviews realized to managers of the centres of formation, are used as tools to obtain information about following topics: recruitment strategies, conventional and not conventional routes of the recruitment, rate rotation, qualification and training of the Spanish trainers. The transcription of the interviews achieve that not always exist a previous plan of recruitment, except that it is a question as big centers of formation. Also, the obtained information indicates a high rate of rotation that affects the trainers ones as professionals since there exists the discontinuity of the formative offer on the labour market.

Sporting bodies have developed guidelines for managing community-level players with suspected concussion in response to international consensus statements on concussion in sport. The purpose of this study was to examine the factors that influence the intended use of concussion guidelines among community-level coaches and sports trainers from two popular football codes in Australia: Australian football and rugby league. Cross-sectional survey. The survey, based on an extended theory of planned behaviour model, was completed by 183 Australian football coaches, 121 Australian football sports trainers, 171 rugby league coaches, and 142 rugby league sports trainers. Personal norms and self-efficacy were significant predictors of intention to use concussion guidelines, although the relationship between self-efficacy and intention was stronger among Australian football coaches than rugby league coaches. Analysis of the salient beliefs that underpin self-efficacy found that coaches, irrespective of football code, felt less familiar (χ(2)=25.70, psports trainers in using the concussion guidelines. At the same time, Australian football personnel, irrespective of their team role, felt that they had insufficient time (χ(2)=8.04, psport concussion guidelines should focus on enhancing self-efficacy and leveraging personal norms. Increasing coaches' familiarity and experience in using the concussion guidelines would also be warranted, as would finding ways to overcome the perceived time and resource constraints identified among Australian football personnel.

Towards the development of full-fledged forest fire information systems

Baetens, J.; De Baets, B.

2012-12-01

Throughout the last decades much efforts have been spent in obtaining an increased understanding of wildfire dynamics and the way it is influenced by prevailing environmental conditions and settings, such as temperature, humidity, topography, vegetation abundance, and so on, since such a profound apprehension is a prerequisite for achieving enhanced wildfire prevention measures, as well as for optimizing fire fighting and disaster management. Amongst other things, this pursuit has culminated in the deployment of wildfire information systems, such as the Canadian Wildfire Information System (CWFIS), the European Forest Fire Information System (EFFIS) and the United States Active Fire Mapping Program and Landscape Fire and Resource Management Planning Tools (LANDFIRE), which inform any interested stakeholder, be it a citizen or a government official, about the current fire risk, the extent and location of current fires, the inflammability of the vegetation, and so on. Taking into account the coverage of these systems, it should be clear that they strongly rely upon satellite imagery that is obtained from dedicated sensors, such as the Moderate-Resolution Imaging Spectroradiometer (MODIS) on board of NASA's Terra and Aqua satellites and the Advanced Very High Resolution Radiometer (AVHRR) that is carried by NOAA satellites, or more general-purpose instruments on board of spacecrafts such as Landsat or SPOT. Yet, to this day the aforementioned information systems have not yet embraced the power of mathematical modeling in order to enable trustworthy forecasts of the spatio-temporal propagation of wildfires given their current extent, which would nonetheless be extremely useful for optimizing fire fighting and disaster management, taking appropriate preventive measures, and so on. The deployment of such full-fledged wildfire information systems requires a high-level integration of (real-time) satellite imagery, weather reports and forecasts, geographic information, and

Biopolymers have received much attention of researchers due to concerns over disposal of plastics, greenhouse gas emission and environmental problems associated with it. Polylactic Acid (PLA) is one of the thermoplastic biopolymer made from lactic acid by using agricultural resources. PLA has received significant interest due to its competitive properties when compared to commodity plastics such as Polyethylene, Polypropylene and Polystyrene. PLA has interesting properties such as high stiffness, UV stability, clear and glossy finish. However, application of PLA is restricted due to its brittle nature. Engineering and thermal properties of PLA can be improved by reinforcing fibres and fillers. Lignocelluloses or natural fibres such as Jute, Hemp, Bamboo, Sisal and Wood fibres can be used as reinforcement. By using natural fibres, a very bio-compostable composite can be produced. In the present study, short fibres from Melia Dubia wood were extracted and used as reinforcement to PLA Bio-Polymer matrix. Characterization of developed composite was obtained using tensile and flexural tests. Tensile test simulation of composite was performed using Altair Hypermesh, a Finite Element (FE) preprocessor and LS-Dyna an explicit FE solver. MAT_01, an elastic material model in LS-Dyna was used to model the behaviour. Further, the design of Root Trainer using developed composite has been explored. A Root Trainer is an aid to the cultivation of seedlings in nurseries. Root Trainer made by using developed composite has advantage of biodegradability and eco-friendly nature.

The aim of this study was to determine whether any correlation exists between the performance of the Mimic® dV-Trainer (Mimic Technologies, Seattle, Wash., USA) and the da Vinci Surgical System (Intuitive Surgical, Sunnyvale, Calif., USA). Twelve participants were recruited, ranging from residents to consultants. We used four training tasks, consisting of 'Pick and Place', 'Peg Board', 'Thread the Rings' and 'Suture Sponge', from the software program of the Mimic dV-Trainer. The performance of the participants was recorded and measured. Additionally, we prepared the same tasks for the da Vinci Surgical System. All participants completed the tasks using the da Vinci Surgical System and were assessed according to time, the Objective Structured Assessment of Technical Skill checklist and the global rating score for endoscopic suturing assessed by two independent blinded observers. After performing these tasks, the participants completed a questionnaire that evaluated the Mimic dV-Trainer's face and content validity. The final results for each participant for the Mimic dV-Trainer and the da Vinci Surgical System were compared. All participants ranked the Mimic dV-Trainer as a realistic training platform that is useful for residency training. There was a significant relationship between the Mimic dV-Trainer and the da Vinci Surgical System in all four tasks. We verified the reliability of the assessment of the checklist and the global rating scores for endoscopic suturing assessed by the two blinded observers using Cronbach's alpha test (r = 0.803, 0.891). We evaluated the concurrent validity of the Mimic dV-Trainer and the da Vinci Surgical System. Our results suggest the possibility that training using the Mimic dV-Trainer may therefore be able to improve the operator's performance during live robot-assisted surgery. © 2013 S.

The key bimanual instrument tasks involved in laparoscopic surgery have been abstracted for use in a virtual reality surgical skills evaluator and trainer. The trainer uses two laparoscopic instruments mounted on a frame with position sensors which provide instrument movement data that is translated into interactive real time graphics on a PC (P133, 16 Mb RAM, graphics acceleration card). An accurately scaled operating volume of 10 cm3 is represented by a 3D cube on the computer screen. "Camera" position and size of target objects can be varied for different skill levels. Targets appear randomly within the operating volume according to the skill task and can be grasped and manipulated with the instruments. Accuracy and errors during the tasks and time to completion are logged. Mist VR has tutorial, training, examination, analysis and configuration modes. Six tasks have been selected and include combinations of instrument approach, target acquisition, target manipulation and placement, transfer between instruments, target contact with optional diathermy, and controlled instrument withdrawal/replacement. Tasks can be configured for varying degrees of difficulty and the configurations saved to a library for reuse. Specific task configurations can be assigned to individual students. In the examination mode the supervisor can select the tasks, repetitions and order and save to a specific file for that trainee. Progress can be assessed and there is the option for playback of the training session or examination. Data analyses permit overall, including task, and right or left hand performances to be quantified. Mist VR represents a significant advance over the subjective assessment of training performances with existing "plastic box" basic trainers.

To investigate the events that could arise when fighting fires in vehicles with compressed hydrogen CFRP (carbon fiber reinforced plastic) composite cylinders, we conducted experiments to examine whether a hydrogen jet flame caused by the activation of the pressure relief device (PRD) can extinguished and how spraying water influences the cylinder and PRD. The experiments clarified that the hydrogen jet flame cannot be extinguished easily with water or dry powder extinguishers and that spraying water during activation of the PRD may result in closure of the PRD, but is useful for maintaining the strength of CFRP composite cylinders for vehicles.

Adolescent fighting affects 25% of youth, with the highest rates among African-Americans and Latinos but little is known about parental views on youth fighting. The purpose of this study was to examine African-American and Latino parents’ perspectives on adolescent fighting and methods to prevent fighting. We conducted four focus groups with parents of African-American and Latino urban adolescents. Focus groups were stratified by race/ethnicity and fighting status. Groups were audiotaped, transcribed, and analyzed by three independent coders using thematic content analysis. Seventy-six percent of the 17 participants were female. Latino parents condoned fighting only as a last resort, and taught children about consequences of fighting, emotional regulation, and non-violent conflict-resolution strategies. African-American parents endorsed teaching non-violent strategies, but expressed some doubts about their effectiveness. African-American parents also suggested corporal punishment, but acknowledged that this may not be an optimal long-term strategy. Positive role modeling and involvement by teachers and other adults were cited as having important roles in fighting prevention. Suggested interventions included teaching adolescents non-violent conflict-resolution skills, anger management, and alternatives to fighting. Parents recommended that violence prevention programs incorporate the experiences of former fighters and be tailored to community needs. Study findings suggest that youth violence-prevention programs may benefit from addressing parental attitudes towards fighting and parent-child communication about fighting, teaching adolescents non-violent conflict-resolution skills, and tailoring programs by race/ethnicity. Promoting positive modeling and involvement by teachers and other adults also may be beneficial. PMID:27186064

Pauser, Johannes; Jendrissek, Andreas; Swoboda, Bernd; Gelse, Kolja; Carl, Hans-Dieter

2011-11-01

To investigate the use of a physical strain trainer for the monitoring of partial weight bearing. Case series with healthy volunteers. Orthopedic clinic. Healthy volunteers (N=10) with no history of foot complaints. Volunteers were taught to limit weight bearing to 10% body weight (BW) and 50% BW, monitored by a physical strain trainer. The parameters peak pressure, maximum force, force-time integral, and pressure-time integral were assessed by dynamic pedobarography when volunteers walked with full BW (condition 1), 50% BW (condition 2), and 10% BW (condition 3). With 10% BW (condition 3), forces with normative gait (condition 1) were statistically significantly reduced under the hindfoot where the physical strain trainer is placed. All pedobarographic parameters were, however, exceeded when the total foot was measured. A limitation to 10% BW with the physical strain trainer (condition 3) was equal to a bisection of peak pressure and maximum force for the total foot with normative gait (condition 1). Halved BW (condition 2) left a remaining mean 82% of peak pressure and mean 59% of maximum force from full BW (condition 1). The concept of controlling partial weight bearing with the hindfoot-addressing device does not represent complete foot loading. Such devices may be preferably applied in cases when the hindfoot in particular must be off-loaded. Other training devices (eg, biofeedback soles) that monitor forces of the total foot have to be used to control partial weight bearing of the lower limb accurately.

Project W-026, Waste Receiving and Processing (WRAP) Facility Module 1: Maximum possible fire loss (MPFL) decontamination and cleanup estimates. Revision 1

International Nuclear Information System (INIS)

Hinkle, A.W.; Jacobsen, P.H.; Lucas, D.R.

1994-01-01

Project W-026, Waste Receiving and Processing (WRAP) Facility Module 1, a 1991 Line Item, is planned for completion and start of operations in the spring of 1997. WRAP Module 1 will have the capability to characterize and repackage newly generated, retrieved and stored transuranic (TRU), TRU mixed, and suspect TRU waste for shipment to the Waste isolation Pilot Plant (WIPP). In addition, the WRAP Facility Module 1 will have the capability to characterize low-level mixed waste for treatment in WRAP Module 2A. This report documents the assumptions and cost estimates for decontamination and clean-up of a maximum possible fire loss (MPFL) as defined by DOE Order 5480.7A, FIRE PROTECTION. The Order defines MPFL as the value of property, excluding land, within a fire area, unless a fire hazards analysis demonstrates a lesser (or greater) loss potential. This assumes failure of both automatic fire suppression systems and manual fire fighting efforts. Estimates were developed for demolition, disposal, decontamination, and rebuilding. Total costs were estimated to be approximately $98M

Liquid metal fires. A review of work status in the United Kingdom

International Nuclear Information System (INIS)

Newman, R.N.; Hargreaves, K.

1983-01-01

Liquid metal coolants (Na and NaK) are used for the transfer of heat in LMFBR circuits. Their high chemical reactivity and the high circuit operating temperatures mean that any leakage of coolant to the atmosphere can result in spontaneous combustion. Additionally spilled coolant may contact and react with structural materials such as concrete. These sodium fires and reactions with concrete are exothermic, and the fires in particular are characterised by significant evolution of heat and release of combustion product aerosols in high concentrations. A major sodium fire places special demands on the integrity of reactor secondary containment structures and may require special measures to control the release of chemically toxic (and possibly radioactive) aerosols to the environment. Precautions must also be taken to minimise damage to equipment, especially safety-related items. Work under way in laboratories in a number of countries is aimed at resolving these issues. These studies comprise investigations of the combustion mechanisms of sodium in both liquid and vapour states, and of the reactions of sodium with structural materials at high temperature. Extensive studies are also under way on the chemical and physical nature and on the behaviour of airborne reaction products released from fires. Data from these studies are used as an input to codes developed to model conditions resulting from sodium fires and thus to provide a basis for the design of containment structures and air clean-up equipment requirements. A knowledge of liquid metal combustion mechanisms is also a necessary adjunct to the development of fire prevention and fire-fighting systems. In the UK fire studies are conducted by CEGB (Berkeley Laboratories), NNC and the UKAEA, and this paper reviews the status of work carried out

The present study examines the patterns and correlates of physical fighting among a school-based population in a low-income country setting. Data on 6235 adolescents aged 11–16 years were derived from the Republic of Ghana contributions to the Global School-based Health Survey. Three thresholds of participation in a physical fight during a 12-month recall period were compared against several independent sociodemographic variables. Bivariate analyses were used to screen for statistically significant associations and multinomial logistic regression was used to examine significant relationships while adjusting for covariates. Within the recall period, 32% of adolescents had reported being involved in two or more physical fights. Those involved in a physical fight during three or more days during the recall period were more likely to have been bullied (relative risk ratios (RRR = 1.86; 99% confidence intervals (CI: 1.38–2.52, have had a troubled experience with alcohol (RRR = 2.202; CI = 1.55–2.64, and miss days of school (RRR = 2.02; CI = 1.39–2.92. When adjusted only for age and sex, having understanding parents was protective (RRR = 0.64; CI = 0.53–0.78 as was having a positive school environment (RRR = 0.73; CI = 0.55–0.97. Our findings suggest that school-based programming which simultaneously targets multiple risk behaviors and conflict resolution may be helpful in interventions to reduce rates of physical fighting.

[Improving the collective self-efficacy of the teams of nurse trainers at IFSI through professional didactics].

The purpose of the study is to show that the analysis of the activity is a factor of construction of the collective self-efficacy of the trainers of five training institutes in nursing care (IFSI). As a collective system of beliefs on the capacity of the group to attain its goals, self-efficacy finds its foundations in the sociocognitive theory which articulates, within a mutual triadic causality, the personal, behavioral and environmental factors of the human agentivity. The personal determiners (self-efficacy, cognitive organization of the activity) are put in connection with the behavioral (production of the performance) and environmental (attribution of skill, professional tasks and standards) factors. The intervention consisted in introducing one hundred and nine nurse trainers to work analysis in a context of hospital reforms. The collective self-efficacy of the trainers appears as a key variable of the success of these reforms. The collective self-efficacy was the object of a pre-test and a qualitative post-test on the basis of motivational indicators, of the effectiveness of the educational realizations to the students and the estimation of the performance of the group to conduct the reform. The level of collective self-efficacy increases and the first realizations maintain the belief of the trainers in their capacity to succeed collectively in the implementation of the training plan. This is the first research in France which shows that the analysis of the activity comes along with an increase of the collective self-efficacy in work. These results question the practices of the trainers beyond the paramedical sector alone.

To analyse the effects of gait therapy for patients after acute stroke in a randomized controlled trial. Fifty-six patients with a mean of 8 days post-stroke participated in: (i) gait trainer exercise; (ii) walking training over ground; or (iii) conventional treatment. Patients in the gait trainer exercise and walking groups practiced gait for 15 sessions over 3 weeks and received additional physiotherapy. Functional Ambulatory Category and several secondary outcome measures assessing gait and mobility were administered before and after rehabilitation and at 6-month follow-up. Patients also evaluated their own effort. Walking ability improved more with intensive walk training compared with conventional treatment; median Functional Ambulatory Category was zero in all patients at the start of the study, but it was 3 in both walk-training groups and 0.5 in the conventional treatment group at the end of the therapy. Median Functional Ambulatory Category was 4 in both walk-training groups and 2.5 in conventional treatment group at 6-month follow-up. Mean accomplished walking distance was not different between the gait trainer exercise and over ground walking groups. Borg scale indicated more effort in over ground walking. Secondary outcomes also indicated improvements. Exercise therapy with walking training improved gait function irrespective of the method used, but the time and effort required to achieve the results favour the gait trainer exercise. Early intensive gait training resulted in better walking ability than did conventional treatment.

Defence-in-depth strategy of fire protection and its relevance after final shutdown (by the example of Germany)

Energy Technology Data Exchange (ETDEWEB)

Beesen, Michael; Ernst, Benjamin; Fischer, Guenter [TUeV SUeD Industrie Service GmbH (Germany)

Nuclear power plants (NPP) are protected against internal and external fires by a fire protection defence-in-depth concept including the following precautionary measures: operational, structural and equipment related fire protection measures as well as manual fire fighting. The fire protection measures are designed in consideration of fires to be expected (from fire loads permanently and temporarily present together with potential ignition sources) in order to prevent a violation of both the protection goals of public law and the nuclear protection goals / radiological safety objectives in case of internal and external fires. The aspect ''What is the future significance of the fire protection defence-in-depth concept?'' needs to be considered with regard to the situation following the final shutdown. From our point of view as a TSO (technical safety organization) both the non-nuclear protection goals (e.g. prevent occurrence of a fire; ensure escape and rescue of humans) as well as the nuclear ones have to be ensured after final shutdown of a nuclear plant. The protection goals of public law will almost completely remain after the plant has stopped commercial operation while the nuclear safety objectives will be stepwise reduced in consideration of the decommissioning status until the end of the nuclear supervision. Nevertheless, the fire protection concept must clearly specify those fire protection measures that are necessary to ensure the plants' safety. The situation on site regularly needs to be under examination to check if the fire protection concept covers all conditions to be considered and if the existing fire protection measures are sufficient or if an adaption is necessary.

This analysis evaluates the existing subsurface non-potable water system from the portal pump to the end of the water line in the South Ramp and determines if the pump size and spacing meets the system pressure and flow requirements for construction operations and incipient fire fighting capability as established in the Subsurface Fire Hazards Analysis (CRWMS M andO 1998b). This analysis does not address the non potable water system in the Cross Drift which is covered under a previous design analysis (CRWMS-M andO 1998a). The Subsurface Fire Hazards Analysis references sections of OSHA 29 CFR 1910 Subpart L for requirements applicable to the incipient fire fighting hose stations used underground. This analysis does not address mechanical system valves, fittings, risers and other components of the system piping. This system is not designed or intended to meet all National Fire Protection Association (NFPA) codes for a fire fighting system but is only considered a backup system to fire extinguishers that are installed throughout the Topopah Springs (TS) Loop and may be used to fight small incipient stage fires

Laparoscopic surgery has established itself as the approach of choice for a multitude of operations in general, urological, and gynecological surgery. A number of factors make performing laparoscopic surgery technically demanding, and as such it is crucial that surgical trainees hone their skills safely on trainers before operating on patients. These can be highly expensive. Here, we describe a novel and upgradable approach to constructing an affordable laparoscopic trainer. A pattern was produced to build an upgradable laparoscopic trainer for less than $100. The basic model was constructed from an opaque plastic crate with plywood base, 2 trocars, and 2 pairs of disposable laparoscopic instruments. A laptop, a light emitting diode (LED), and a fixed webcam were utilized to visualize the box interior. An enhanced version was also created, as an optional upgrade to the basic model, featuring a neoprene-trocar interface and a simulated mobile laparoscope. The described setup allowed trainees to gain familiarity with laparoscopic techniques, beginning with simple manipulation and then progressing through to more relevant procedures. Novices began by moving easy-to-grasp objects between containers and then attempting more challenging manipulations such as stacking sugar cubes, excising simulated lesions, threading circular mints onto cotton, and ligating fastened drinking straws. These techniques have introduced the necessity of careful instrument placement and have increased trainees' dexterity with laparoscopy. Here, we have outlined an upgradable and affordable alternative laparoscopic trainer that has given many trainees crucial experience with laparoscopic techniques, allowing them to safely improve their manual skill and confidence.

To present recommendations for the certified athletic trainer in the management of type 1 diabetes in the athlete. In managing diabetes, the most important goal is to keep blood glucose levels at or as close to normal levels as possible without causing hypoglycemia. This goal requires the maintenance of a delicate balance among hypoglycemia, euglycemia, and hyperglycemia, which is often more challenging in the athlete due to the demands of physical activity and competition. However, effectively managing blood glucose, lipid, and blood pressure levels is necessary to ensuring the long-term health and well-being of the athlete with diabetes. These recommendations are intended to provide the certified athletic trainer participating in the management of an athlete with type 1 diabetes mellitus with the specific knowledge and problem-solving skills needed. Athletic trainers have more contact with the athlete with diabetes than most members of the diabetes management team do and so must be prepared to assist the athlete as required.
