    Not only the health service but also several other humanitarian institutions and societies were active in Abbazia÷Opatija, the most important town on the once Austrian Riviera, the town that was also known as the Austrian Nice. The most important of the societies was The Health Resort Opatija Volunteer Fire Brigade and Rescue Society. The authors of this article have been particularly interested in the society's founding and its activity until it moved into the new building at 6, St. Florjan's Street in 1910. The fast urbanisation and the development of the industry raised the need of the well organised activity of putting out fires. The German gymnastics societies were the first to include the education and the skills development of the volunteer firemen into their programmes. The first volunteer fire brigades appeared in Austria after 1863. The huge fire that broke out in Vienna in 1881 showed that the fast and efficient rescuing demanded a well prepared organization of a team of rescuers. Based on the initiative of the chimney sweep Franz Drescher and The South Railway Company, the volunteer fire brigade was founded in Opatija already in 1886. The founding of the volunteer rescue society was based on the idea given by dr. Jaromir Mundy, the permanent guest in Opatija and a friend of prof. dr. Theodor Billroth, in 1894. The intertwining activity of the both societies resulted in their formal joining. The head physician became dr. Franz Tripold, the chief commander was Franz Doberlet junior. For his special merits, the general assembly of the Health Resort Opatija Volunteer Fire Brigade and Rescue Society appointed him the honourable commander of the society in 1903 and he received a special photo album with the photos of the volunteer firemen and the rescuers' practice. The Emperor Franz Joseph I Jubilee Fire Station, the Rescue Station And the Sanatorium (Kaiser Franz Joseph I Jubiläums - Feuerwehrrüstungshaus, Rettungsstation und Erholungsheim) was given to

    Full Text Available The All-Russian Congress “Fire Stop Moscow” was de-voted to the analysis of the four segments of the industry of fire protection systems and technologies: the design of fire protec-tion systems, the latest developments and technologies of active and passive fire protection of buildings, the state and the devel-opment of the legal framework, the practice of fire protection of buildings and structures. The forum brought together the repre-sentatives of the industry of fire protection systems, scientists, leading experts, specialists in fire protection and representatives of construction companies from different regions of Russia. In parallel with the Congress Industrial Exhibition of fire protection systems, materials and technology was held, where manufacturers presented their products. The urgency of the “Fire Stop Moscow” Congress in 2015 organized by the Congress Bureau ODF Events lies primarily in the fact that it considered the full range of issues related to the fire protection of building and construction projects; studied the state of the regulatory framework for fire safety and efficiency of public services, research centers, private companies and busi-nesses in the area of fire safety. The main practical significance of the event which was widely covered in the media space, was the opportunity to share the views and information between management, science, and practice of business on implementing fire protection systems in the conditions of modern economic relations and market realities. : congress, fire protection, systems, technologies, fire protection systems, exhibition

    Although hospice volunteer programs contribute to patient care, little is known about their utilization and adaptation of technology. A survey was posted to the Hospice Volunteer Association Web site to assess technology use among volunteer coordinators and volunteers. Results revealed that participants have access to computers, Internet, and e-mail at the hospice agency and routinely use cellular phones and e-mail. Despite the use of technology, communication problems with volunteers hindered the coordinator's ability to manage scheduling, training, and volunteer assignments for patient care. Coordinators and volunteers felt comfortable utilizing technology but were less comfortable using technology in the patients' home. Several areas are identified for development and integration of advanced technology in volunteer programs. Future research is needed to ease technology implementation and increase volunteer acceptance.

  5. Fiber optic fire detection technology

    Electrostatic application of paint was, and still is, the most technically feasible method of reducing VOC (volatile organic compounds) emissions, while reducing the cost to apply the coatings. Prior to the use of electrostatics, only two sides of the traditional fire triangle were normally present in the booth, fuel (solvent), and oxygen (air). Now the third leg (the ignition source) was present at virtually all times during the production operation in the form of the electrostatic charge and the resulting energy in the system. The introduction of fiber optics into the field of fire detection was for specific application to the electrostatic painting industry, but specifically, robots used in the application of electrostatic painting in the automotive industry. The use of fiber optics in this hazard provided detection for locations that have been previously prohibited or inaccessible with the traditional fire detection systems. The fiber optic technology that has been adapted to the field of fire detection operates on the principle of transmission of photons through a light guide (optic fiber). When the light guide is subjected to heat, the cladding on the light guide melts away from the core and allows the light (photons) to escape. The controller, which contains the emitter and receiver is set-up to distinguish between partial loss of light and a total loss of light. Glass optical fibers carrying light offer distinct advantages over wires or coaxial cables carrying electricity as a transmission media. The uses of fiber optic detection will be expanded in the near future into such areas as aircraft, cable trays and long conveyor runs because fiber optics can carry more information and deliver it with greater clarity over longer distances with total immunity to all kinds of electrical interference

    The workshop that was held in Madrid 25-27 May 1994 included participation by experts from 16 countries. They represented such diverse fields and disciplines as technology, governmental regulation, economics, and environment. Thus, the participants provided an excellent cross section of key areas and a diversity of viewpoints. At the workshop, a broad range of topics regarding gas-fired electric power generation was discussed. These included political, regulatory and financial issues as well as more specific technical questions regarding the environment, energy efficiency, advanced generation technologies and the status of competitive developments. Important technological advances in gas-based power and CHP technologies have already been achieved including higher energy efficiency and lower emissions, with further improvements expected in the near future. Advanced technology trends include: (a) The use of gas technology to reduce emissions from existing coal-fired power plants. (b) The wide-spread application of combined-cycle gas turbines in new power plants and the growing use of aero-derivative gas turbines in CHP applications. (c) Phosphoric acid fuel cells that are being introduced commercially. Their market penetration will grow over the next 10 years. The next generation of fuel cells (solid oxide and molten carbonate) is expected to enter the market around the year 2000. (EG)

    Full Text Available We evaluated the potential of a fiber optic cable connected to distributed temperature sensing (DTS technology to withstand wildland fire conditions and quantify fire behavior parameters. We used a custom-made ‘fire cable’ consisting of three optical fibers coated with three different materials—acrylate, copper and polyimide. The 150-m cable was deployed in grasslands and burned in three prescribed fires. The DTS system recorded fire cable output every three seconds and integrated temperatures every 50.6 cm. Results indicated the fire cable was physically capable of withstanding repeated rugged use. Fiber coating materials withstood temperatures up to 422 °C. Changes in fiber attenuation following fire were near zero (−0.81 to 0.12 dB/km indicating essentially no change in light gain or loss as a function of distance or fire intensity over the length of the fire cable. Results indicated fire cable and DTS technology have potential to quantify fire environment parameters such as heat duration and rate of spread but additional experimentation and analysis are required to determine efficacy and response times. This study adds understanding of DTS and fire cable technology as a potential new method for characterizing fire behavior parameters at greater temporal and spatial scales.

  9. Assessing the Role of Technology in Citizen Science: A Volunteer's Perspective

    From a volunteer's perspective, citizen science can provide a direct connection between outdoor enthusiasts and the scientists who study these natural environments. These experiences are both rewarding and engaging, as participants become aware of field sites, the scientific method, and their own environmental impacts. Recent technological advances (i.e. smart phones and mobile applications) have the potential to transform citizen science, specifically as technology can both enable and modernize the networks between a large community of potential volunteers and scientists using these data. By providing volunteers who venture into largely understudied and remote areas with an easy method for data collection and entry, it becomes easier to encourage volunteer engagement in science, while maintaining quality control over the data collection process. Participating in Adventure Scientists' projects demonstrates the application of technology as an effective engagement tool, especially when compared to traditional pen and paper surveys often conducted. Pairing volunteers with simple, familiar technology increases engagement, particularly for volunteers otherwise intimidated by the scientific process. When equipped with useful features, such as GPS functionality, smartphone apps offer a simple and standardized method of data collection and description. Yet a variety of factors can complicate field sampling; final choices are ultimately left to the judgment of the volunteer and perhaps could be guided by use of a phone/app. Importantly, Adventure Scientists conducts follow ups and volunteer surveys, which are critical to the continued evaluation of volunteer experiences and the sampling methods themselves. For future projects, creating a forum in which scientists and volunteers can interact (perhaps also through a phone app) could provide scientific context for volunteers, further investing them in the scientific process and their continued participation. Overall, the

    Building fire is a risky activity that can lead to disaster and massive destruction. The management and disposal of building fire has always attracted much interest from researchers. Integrated Virtual Geographic Environment (VGE) is a good choice for building fire safety management and emergency decisions, in which a more real and rich fire process can be computed and obtained dynamically, and the results of fire simulations and analyses can be much more accurate as well. To modelling building fire scene with VGE, the application requirements and modelling objective of building fire scene were analysed in this paper. Then, the four core elements of modelling building fire scene (the building space environment, the fire event, the indoor Fire Extinguishing System (FES) and the indoor crowd) were implemented, and the relationship between the elements was discussed also. Finally, with the theory and framework of VGE, the technology of building fire scene system with VGE was designed within the data environment, the model environment, the expression environment, and the collaborative environment as well. The functions and key techniques in each environment are also analysed, which may provide a reference for further development and other research on VGE.

  13. Does Suspected Sleep Disordered Breathing Impact on the Sleep and Performance of Firefighting Volunteers during a Simulated Fire Ground Campaign?

    Full Text Available Adequate sleep is fundamental to workplace performance. For volunteer firefighters who work in safety critical roles, poor performance at work can be life threatening. Extended shifts and sleeping conditions negatively impact sleep during multi-day fire suppression campaigns. Having sleep disordered breathing (SDB could contribute further to sleep deficits. Our aim was to investigate whether those with suspected SDB slept and performed more poorly during a fire ground simulation involving sleep restriction. Participants, n = 20 participated in a 3-day-4-night fire ground simulation. Based on oximetry desaturation index data collected during their participation, participants were retrospectively allocated to either a SDB (n = 8 or a non-SDB group (n = 12. The simulation began with an 8 h Baseline sleep (BL followed by two nights of restricted (4 h sleep and an 8 h recovery sleep (R. All sleeps were recorded using a standard electroencephalography (EEG montage as well as oxygen saturation. During the day, participants completed neurobehavioral (response time, lapses and subjective fatigue tasks. Mixed effects ANOVA were used to compare differences in sleep and wake variables. Analyses revealed a main effect of group for Total sleep (TST, REM , wake after sleep onset (WASO and Arousals/h with the SDB group obtaining less TST and REM and greater WASO and Arousals/h. The group × night interaction was significant for N3 with the SDB group obtaining 42 min less during BL. There was a significant main effect of day for RRT, lapses and subjective fatigue and a significant day × group interaction for RRT. Overall, the SDB group slept less, experienced more disturbed sleep and had poorer response time performance, which was exacerbated by the second night of sleep restriction. This could present a safety concern, particularly during longer campaigns and is worthy of further investigation. In addition, we would recommend promotion of awareness of SDB, its

Altered cardiovascular disease endpoints after the firefighting exercise period were most likely due to complex effects from PM exposure, physical...

  15. Introduction: Technologies of Fire in Nineteenth-Century British Culture

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Cultural histories of nineteenth-century Britain have studied the important physical and psychological transformations caused by the industrialization of light. Gaslight, though discovered prior to the nineteenth century, became aligned with the era’s narratives of national and industrial progress, an arc that, one might argue, culminated in the growing popularity of electric light at the end of the century. Yet, despite these new technologies of ‘artificial light’, ‘natural’ wood and coal fires remained popular in British culture. This issue explores fire as a visual and narrative technology in art, literature, and public displays by examining the ways in which it evoked competing symbolic values, such as primitivism and modernity, vitality and destruction, intimacy and spectacle. The reading order mixes articles and shorter pieces together to demonstrate the continuities of fire across various sites, including: the domestic fireside, the tallow candle, theatrical conflagrations, Turner’s fires, fireworks, funeral pyres, subterranean fire, solar fire, and a coal-ship fire.

     Informal caregivers of bedridden elders need a respite. One form of obtaining a respite is through volunteers who are contacted by means of information and communication technology (ICT).  A qualitative study was carried out in a low-income district in Santiago, Chile, to learn about how caregivers of bedridden elders perceive the possibility of using ICT to access this respite. In-depth interviews were carried out and transcribed verbatim, then analysed using open coding. Results: The results reveal that caregivers are willing to receive a volunteer in their home and use ICT to communicate with them, although a discrepancy exists between the use of devices connected to the Internet and feature phones. Conclusion: This study concludes that informal caregivers of bedridden elders have a favourable disposition towards accessing a respite system by means of ICT based on a peer-to-peer economy.

    Coalfield fire has become a global disaster, especially in China, which lost a large number of coal resources every year, and caused serious destruction of ecological environment. Coalfield fire area has become urgent to solve the problem for the complex, combustion long-time, wide range, fire source hidden, and controlling difficultly in the formed evolution process. At present, surface coal fire areas prospecting technology mainly have visible light on surface, surface radar remote sensing technology, air ground integration technology. Detecting hidden fire source technology are infrared thermal imaging technology, method of radon-test. The technologies of monitoring and early warning for fire areas with ad-hoc, intelligent monitoring for infrared thermal imaging real time networks are applied. The idea of district controlling as "prevention-control-extinguishing" is established and in-site applications, which the technologies and equipment of fire prevention and extinguishment include the inorganic filling plugging, liquid carbon dioxide, and series of colloidal materials.

    Tomás-Navarro, María; Vallejo, Fernando; Sentandreu, Enrique; Navarro, Jose L; Tomás-Barberán, Francisco A

    2014-01-08

    The effect of two technological treatments on orange juice flavanone bioavailability in humans was assessed. Processing affected flavanone solubility and particle size of the cloud. Volunteers were stratified in high, medium, and low urinary excretion capabilities. Flavanones from high-pressure homogenized juice showed better absorption than those of conventional pasteurized juice in high excretors. These differences were not observed in medium and low excretors. High flavanone excretors took advantage of the high-pressure homogenization juice attributes (smaller cloud particle size) and showed an improved absorption/excretion. Stratification of the individuals by their excretion capability is more relevant than technological treatments in terms of flavanone bioavailability. This stratification should be considered in clinical studies with citrus juices and extracts as it could explain the large interindividual variability that is often observed.

    Fire intervention technology (detection and suppression) is a critical part of the strategy of spacecraft fire safety. This paper reviews the status, trends, and issues in fire intervention, particularly the technology applied to the protection of the International Space Station and future missions beyond Earth orbit. An important contribution to improvements in spacecraft fire safety is the understanding of the behavior of fires in the non-convective (microgravity) environment of Earth-orbiting and planetary-transit spacecraft. A key finding is the strong influence of ventilation flow on flame characteristics, flammability limits and flame suppression in microgravity. Knowledge of these flow effects will aid the development of effective processes for fire response and technology for fire suppression.

    1997-01-17

    The purpose of this work was to investigate the utility of electronic aroma detection technologies for the detection and identification of accelerant residues in suspected arson debris. Through the analysis of known accelerant residues, a trained neural network was developed for classifying suspected arson samples. Three unknown fire debris samples were classified using this neural network. The item corresponding to diesel fuel was correctly identified every time. For the other two items, wide variations in sample concentration and excessive water content, producing high sample humidities, were shown to influence the sensor response. Sorbent sampling prior to aroma detection was demonstrated to reduce these problems and to allow proper neural network classification of the remaining items corresponding to kerosene and gasoline.

  12. HOT AEROSOL FIRE EXTINGUISHING AGENTS AND THE ASSOCIATED TECHNOLOGIES: A REVIEW

    Directory of Open Access Journals (Sweden)

    Xiaotian Zhang

    2015-09-01

    Full Text Available AbstractSince the phase out of Halon extinguishers in the 1980s, hot aerosol fire suppression technology has gained much attention. Unlike traditional inert gas, foam, water mist and Halon fire suppression agents, hot aerosol fire extinguishing agents do not need to be driven out by pressurized gases and can extinguish class A, B, C, D and K fires at 30 to 200 g/m3. Generally, hot aerosol fire extinguishing technology has developed from a generation I oil tank suppression system to a generation III strontium salt based S-type system. S-type hot aerosol fire extinguishing technology greatly solves the corrosion problem of electrical devices and electronics compared to potassium salt based generation I & II hot aerosol fire extinguishing technology. As substitutes for Halon agents, the ODP and GWP values of hot fire extinguishing aerosols are nearly zero, but those fine aerosol particles can cause adverse health effects once inhaled by human. As for configurations of hot aerosol fire extinguishing devices, fixed or portable cylindrical canisters are the most common among generation II & III hot aerosol fire extinguishers across the world, while generation I hot aerosol fire suppression systems are integrated with the oil tank as a whole. Some countries like the U.S., Australia, Russia and China, etc. have already developed standards for manufacturing and quality control of hot aerosol fire extinguishing agents and norms for hot aerosol fire extinguishing system design under different fire protection scenarios. Coolants in hot aerosol fire suppression systems, which are responsible for reducing hot aerosol temperature to avoid secondary fire risk are reviewed for the first time. Cooling effects are generally achieved through vaporization and endothermic chemical decomposition of coolants. Finally, this review discussed areas applying generation I, II or III hot aerosol fire suppression technologies. The generation III hot aerosol fire extinguishing

    This Final Report summarizes the progress of Phases 3,3A and 4 of a waste technology Demonstration Project sponsored under a DOE Environmental Management Research and Development Program and administered by the U.S. Department of Energy National Energy Technology Laboratory-Morgantown (DOE-NETL) for an ''Innovative Fossil Fuel Fired Vitrification Technology for Soil Remediation''. The Summary Reports for Phases 1 and 2 of the Program were previously submitted to DOE. The total scope of Phase 3 was to have included the design, construction and demonstration of Vortec's integrated waste pretreatment and vitrification process for the treatment of low level waste (LLW), TSCA/LLW and mixed low-level waste (MLLW). Due to funding limitations and delays in the project resulting from a law suit filed by an environmental activist and the extended time for DOE to complete an Environmental Assessment for the project, the scope of the project was reduced to completing the design, construction and testing of the front end of the process which consists of the Material Handling and Waste Conditioning (MH/C) Subsystem of the vitrification plant. Activities completed under Phases 3A and 4 addressed completion of the engineering, design and documentation of the MH/C System such that final procurement of the remaining process assemblies can be completed and construction of a Limited Demonstration Project be initiated in the event DOE elects to proceed with the construction and demonstration testing of the MH/C Subsystem. Because of USEPA policies and regulations that do not require treatment of low level or low-level/PCB contaminated wastes, DOE terminated the project because there is no purported need for this technology.

    The thesis discusses forest fire occurrence in the Karst forest management region in the period from 1995 to 2009. Data analysis has shown that fire occurrence has two season peaks which are highly associated with human activities in the natural environment (land cultivation, railway). Therefore fire mostly starts in unwooded areas, from where the wind spreads it into the woods. Most frequently it occurs in deciduous forests, and the largest burnt areas occur in coniferous forests.

    2018-02-01

    Full Text Available As health-care professionals, there often comes a time in our career when we are intrigued by the possibility of participating in humanitarian work in underserved countries. However, the desire to serve is often tempered by some ambivalence about whether our skill sets are applicable in less technologically advanced health-care settings. Furthermore, there may be some concern about the cultural and logistical challenges one might face while working overseas. A volunteer may also be worried that, despite their best intentions, the medical personnel in the host country will not take advantage of our knowledge and their patients will not achieve the best results. As a consequence, a talented and well-intentioned professional may decide not to volunteer, resulting in a lost opportunity to participate in what can be an extremely rewarding experience. I will be discussing a number of key factors that can strongly influence the quality of one’s experience from the perspective of a Hand Specialist. My comments will primarily be a reflection of my personal experience over 20 years as a member of Health Volunteers Overseas (www.hvousa.org.

    2017-06-01

    Full Text Available The treatment with fire retardant chemicals is the most effective process to protect wood and wood based products from fire. Therefore, use of fire retardant chemicals has been increased. However, the fire retardant chemicals have an effect on other physical, mechanical and some technological properties of the materials treated with them. In this study the effect of various fire retardant chemicals in different concentrations on the technological properties of plywood were examined. Poplar (Populus deltoides and scots pine (Pinus sylvestris L. were used as wood species; zinc borate, monoammonium phosphate (MAP and ammonium sulfate were used as fire retardant chemicals and UF resin was used as adhesive. The veneer sheets were treated by immersion and three different concentrations, such as 5%, 7% and 10% aqueous solutions were selected. Mechanical properties of plywood panels, such as the shear strength, bending strength and the modulus of elasticity were determined according to EN 314-1, EN 310, respectively. The surface roughness of the veneer sheets was determined according to DIN 4768 standard. As a result of this study, it was found that all the mechanical strength values of panels produced by using the veneers treated with fire retardant chemicals were lower than those of control panels. With the increasing of the solution concentration their values decreased while the surface roughness values increased.

    2010-07-01

    Coal fires are a significant problem around the world, particularly in China, India, and the United States. Coal fires burn thousands of tons of coal reserves and lead to serious problems for the environment, degradation and destruction of landscape, and harm public health. Technology, such as spectrology analysis of signatures with high temperature activity can be used to calculate vegetation algorithms and soil indexes, and multispectral survey data in the thermal channels of scanners. This paper presented the perspectives of technology development in coal fires and the approach to the detection, monitoring, and quantitative estimation of coal fires by the instruments using geographic information systems. Specifically, the paper considered the use of coal fire fragment monitoring technology from data of a diachronous survey obtained by Landsat satellites, to classify dangerous coal waste banks of the Donbass Mine located in Ukraine. The paper provided a description of the study area and discussed the detection technology of temperature-active waste banks. It was concluded that geoinformation technology provides an opportunity to effectively mark mining dumps, in particular, waste banks in multispectrum space images made by Landsat satellites. 7 refs., 6 figs.

  6. New technological developments in oil well fire fighting equipment and methods

    1995-12-31

    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.

  7. Technology Roadmap: High-Efficiency, Low-Emissions Coal-Fired Power Generation

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2012-07-01

    Coal is the largest source of power globally and, given its wide availability and relatively low cost, it is likely to remain so for the foreseeable future. The High-Efficiency, Low-Emissions Coal-Fired Power Generation Roadmap describes the steps necessary to adopt and further develop technologies to improve the efficiency of the global fleet of coal. To generate the same amount of electricity, a more efficient coal-fired unit will burn less fuel, emit less carbon, release less local air pollutants, consume less water and have a smaller footprint. High-efficiency, low emissions (HELE) technologies in operation already reach a thermal efficiency of 45%, and technologies in development promise even higher values. This compares with a global average efficiency for today’s fleet of coal-fired plants of 33%, where three-quarters of operating units use less efficient technologies and more than half is over 25 years old. A successful outcome to ongoing RD&D could see units with efficiencies approaching 50% or even higher demonstrated within the next decade. Generation from older, less efficient technology must gradually be phased out. Technologies exist to make coal-fired power generation much more effective and cleaner burning. Of course, while increased efficiency has a major role to play in reducing emissions, particularly over the next 10 years, carbon capture and storage (CCS) will be essential in the longer term to make the deep cuts in carbon emissions required for a low-carbon future. Combined with CCS, HELE technologies can cut CO2 emissions from coal-fired power generation plants by as much as 90%, to less than 100 grams per kilowatt-hour. HELE technologies will be an influential factor in the deployment of CCS. For the same power output, a higher efficiency coal plant will require less CO2 to be captured; this means a smaller, less costly capture plant; lower operating costs; and less CO2 to be transported and stored.

    2004-01-01

    The overall vision for FIRE [Fusion Ignition Research Experiment] is to develop and test the fusion plasma physics and plasma technologies needed to realize capabilities of the ARIES-RS/AT power plant designs. The mission of FIRE is to attain, explore, understand and optimize a fusion dominated plasma which would be satisfied by producing D-T [deuterium-tritium] fusion plasmas with nominal fusion gains ∼10, self-driven currents of ∼80%, fusion power ∼150-300 MW, and pulse lengths up to 40 s. Achieving these goals will require the deployment of several key fusion technologies under conditions approaching those of ARIES-RS/AT. The FIRE plasma configuration with strong plasma shaping, a double null pumped divertor and all metal plasma-facing components is a 40% scale model of the ARIES-RS/AT plasma configuration. ''Steady-state'' advanced tokamak modes in FIRE with high beta, high bootstrap fraction, and 100% noninductive current drive are suitable for testing the physics of the ARIES-RS/A T operating modes. The development of techniques to handle power plant relevant exhaust power while maintaining low tritium inventory is a major objective for a burning plasma experiment. The FIRE high-confinement modes and AT-modes result in fusion power densities from 3-10 MWm -3 and neutron wall loading from 2-4 MWm -2 which are at the levels expected from the ARIES-RS/AT design studies

    2016-02-01

    In recent years the promotion of marine observations based on volunteer participation, known as Citizen Science, has provided environmental data with unprecedented resolution and coverage. The Citizen Science based approach has the additional advantage to engage people by raising awareness and knowledge of marine environmental problems. The technological advances in embedded systems and sensors, enables citizens to create their own devices (known as DIY, Do-It-Yourself, technologies) for monitoring the marine environment. Within the context of the CITCLOPS project (www.citclops.eu), a DIY instrument was developed to monitor changes on water transparency as a water quality indicator. The instrument, named KdUINO, is based on quasi-digital sensors controlled by an open-hardware (Arduino) board. The sensors measure light irradiance at different depth and the instrument automatically calculates the light diffuse attenuation Kd coefficient to quantify the water transparency. The buoy construction is an ideal activity for creative STEM programming. Several workshops in high schools were done to show to the students how to construct their own buoy. Some of them used the buoy to develop their own scientific experiments. In order to engage students more motivated in artistic disciplines, the research group developed also a sonification system that allows creating music and graphics using KdUINO measurements as input data.

  15. Current and advanced NO/sub x/-control technology for coal-fired industrial boilers

    Energy Technology Data Exchange (ETDEWEB)

    1978-12-01

    A NOx-control-technology assessment study of coal-fired industrial boilers was conducted to examine the effectiveness of combustion-modification methods, including low excess air, staged combustion, and burner modifications. Boiler types considered included overfed and underfed stokers, spreader stokers, pulverized-coal and coal-fired cyclone units. Significant variations in NOx emissions occur with boiler type, firing method, and coal type; a relative comparison of emission-control performance, cost, and operational considerations is presented for each method. Baseline (as-found) emissions from grate-fired stokers were shown to be in the range of 200 to 300 ppM. Similarly, as-found emissions from suspension-fired units were quite low (350 to 600 ppM) as compared to comparably designed utility-sized units. Low excess air was shown to be the most effective method on existing units, reducing emissions by approximately 10%. Evaluation of staged combustion and burner modification, however, were limited due to current boiler designs. Major hardware modification/design and implementation are necessary before the potential of these techniques can be fully evaluated. The study emphasized the numerous operational factors that are of major importance to the user in selecting and implementing a combustion-modification program, including energy considerations, incremental capital and operating costs, corrosion, secondary pollutants, and retrofit potential.

    2015-01-01

    Highlights: • Pre-drying and water recovery technologies were used to conserve energy and water. • The energy and water conservation potential were analyzed with reference cases. • The air-cooling unit produces water when the water content of lignite is high enough. • Influences of main parameters on energy and water conservation were analyzed. - Abstract: Lignite is considered as a competitive energy raw material with high security of supply viewed from a global angle. However, lignite-fired power plants have many shortcomings, including high investment, low energy efficiency and high water use. To address these issues, the drying and water recovery technologies are integrated within lignite-fired power plants. Both air-cooling and wet-cooling units with three kinds of lignite as feeding fuel were analyzed quantitatively. Results showed that energy conservation and water conservation are obtained simultaneously. The power plant firing high moisture lignite becomes more environmental friendly with higher power generation efficiency and a lower water makeup rate than the one firing low moisture lignite. And further calculation revealed that the air-cooling unit needs no makeup water and even produces some water as it generates power, when the water carrying coefficient is higher than 40 g/MJ.

  19. The optimum coal firing solution: ABB supercritical technology

    Energy Technology Data Exchange (ETDEWEB)

    Kawa, P.; Scarlin, B.; Ericson, A. [ABB Combustion Engineering (Germany)

    1998-12-01

    Today`s increasingly complex market demands new performance standards in fossil fuelled power plants. The requirements for improved efficiency, lower operating costs, high reliability and reduced emissions indicate that power plant developers and utilities consider not only capital equipment cost, but total evaluated costs. To meet these challenges the industry, is turning their attention to advanced cycle power plants. Advanced cycle power plants, typically in the form of supercritical pressure operation, have historically been reserved for use in the United States, Western Europe, and Japan. Over the last 15 years, however, they have gained prominence in portions of the Asian market and it is expected that an increasing number of customers will continue to plan for supercritical power plants in their systems. The discussion explores three areas. Initially, it outlines the current market and future trends in supercritical design and technology necessary to meet increasingly challenging efficiency and emission expectations. Second, it highlights the benefits of utilizing the supercritical cycle. Finally, it details the design and operational differences between supercritical steam and power generation technology and traditional subcritical cycles. Steam turbines, heat recovery systems, superheaters, and furnace walls are discussed with respect to design and operation. 23 figs.

    Ochoa, C. G.; Cram, D.; Hatch, C. E.; Tyler, S. W.

    2014-12-01

    Distributed temperature sensing (DTS) technology offers a viable alternative for accurately measuring wildland fire intensity and distribution in real time applications. We conducted an experiment to test the use of DTS as an alternative technology to monitor prescribed fire temperatures in real time and across a broad spatial scale. The custom fiber-optic cable consisted of three fiber optic lines buffered by polyamide, copper, and polyvinyl chloride, respectively, each armored in a stainless steel tube backfilled with Nitrogen gas. The 150 m long cable was deployed in three different 20 by 26 m experimental plots of short-grass rangeland in central New Mexico. Cable was arranged to maximize coverage of the experimental plots and allow cross-comparison between two main parallel straight-line sections approximately 8 m apart. A DTS system recorded fire temperatures every three seconds and integrated every one meter. A series of five thermocouples attached to a datalogger were placed at selected locations along the cable and also recorded temperature data every three seconds on each fiber. Results indicate that in general there is good agreement between thermocouple-measured and DTS-measured temperatures. A close match in temperature between DTS and thermocouples was particularly observed during the rising limb but not so much during the decline. The metal armoring of the fiber-optic cable remained hot longer than the thermocouples after the flames had passed. The relatively short-duration, high-intensity, prescribed burn fire in each plot resulted in temperatures reaching up to 450 degrees Celsius. In addition, DTS data allow for illustration of the irregular nature of flame speed and travel path across the rangeland grasses, a phenomenon that was impossible to quantify without the use of this tool. This study adds to the understanding of using DTS as a new alternative tool for better characterizing wildland fire intensity, distribution and travel patterns, and

    2014-10-01

    Full Text Available Multi-sensor and information fusion technology based on Dempster-Shafer evidence theory is applied in the system of a building fire alarm to realize early detecting and alarming. By using a multi-sensor to monitor the parameters of the fire process, such as light, smoke, temperature, gas and moisture, the range of fire monitoring in space and time is expanded compared with a single-sensor system. Then, the D-S evidence theory is applied to fuse the information from the multi-sensor with the specific fire model, and the fire alarm is more accurate and timely. The proposed method can avoid the failure of the monitoring data effectively, deal with the conflicting evidence from the multi-sensor robustly and improve the reliability of fire warning significantly.

    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

    If campaigns do not accommodate this view, all but a hard core of regulars and fired-up partisans will drift away, leaving it for staffers and hired hands to do all the hard work of identifying voters, canvassing people by foot and by phone, and turning out the vote. [...] ironically, a campaign...... that is singleminded in its instrumental pursuit of victory can thus be less effective than one that is more accommodating- a campaign that makes room for volunteers by accepting that, unlike staffers, they come to politics with a different perspective and conception of what is and ought to be going on....

    Full Text Available O objetivo deste estudo foi determinar as condições de trabalho e o nível de treinamento das brigadas voluntárias de prevenção e combate aos incêndios florestais do Jardim Botânico de Brasília, da Reserva Ecológica do IBGE e da fazenda Água Limpa da Universidade de Brasília. Os estudos foram realizados no primeiro semestre de 2000 na sede das três brigadas, localizadas nas respectivas Unidades de Conservação, tendo como metodologia o emprego de questionários e entrevistas com os brigadistas e coordenadores. O conjunto de dados foi analisado para as três brigadas, mostrando que o melhor nível de treinamento e satisfação dos brigadistas foi encontrado na brigada da Reserva Ecológica do IBGE e o pior, na brigada da fazenda Água Limpa da UnB. As três brigadas não contam com equipamentos de proteção individual para todos os brigadistas, faltando também equipamentos de combate e ferramentas. Nenhuma brigada dispõe de máquinas para manutenção de estradas e aceiros. Somente a brigada da Reserva Ecológica do IBGE conta com caminhão-pipa para ações de combate. A brigada da fazenda Água Limpa foi a que apresentou maior participação em campanhas educativas junto às comunidades do entorno. Pode-se concluir que, de maneira geral, as brigadas apresentaram bom nível de capacitação e treinamento, demonstrando que apesar da limitação de equipamentos e ferramentas têm conseguido debelar pequenos focos de incêndios florestais. O problema mais grave verificado nas três brigadas foi a falta de equipamentos de proteção individual para todos participantes de ações de combate, gerando riscos de acidentes.The objective of this study was to determine the working conditions and training level of forest fire volunteers of the Jardim Botânico de Brasília, IBGE Ecological Reserve and Água Limpa Farm, Universidade de Brasília.

    The goal of this project is to provide a technical review and evaluation of various carbon dioxide (CO{sub 2}) capture technologies, with a focus on the applicability to lignite-fired facilities within North Dakota. The motivation for the project came from the Lignite Energy Council's (LEC's) need to identify the feasibility of CO{sub 2} capture technologies for existing North Dakota lignite-fired, pulverized coal (pc) power plants. A literature review was completed to determine the commercially available technologies as well as to identify emerging CO{sub 2} capture technologies that are currently in the research or demonstration phase. The literature review revealed few commercially available technologies for a coal-fired power plant. CO{sub 2} separation and capture using amine scrubbing have been performed for several years in industry and could be applied to an existing pc-fired power plant. Other promising technologies do exist, but many are still in the research and demonstration phases. Oxyfuel combustion, a technology that has been used in industry for several years to increase boiler efficiency, is in the process of being tailored for CO{sub 2} separation and capture. These two technologies were chosen for evaluation for CO{sub 2} separation and capture from coal-fired power plants. Although oxyfuel combustion is still in the pilot-scale demonstration phase, it was chosen to be evaluated at LEC's request because it is one of the most promising emerging technologies. As part of the evaluation of the two chosen technologies, a conceptual design, a mass and energy balance, and an economic evaluation were completed.

    Full Text Available Burning of fossil fuels is the major source of energy in today's global economy with over one-third of the world's powergeneration derived from coal combustion. Although coal has been a reliable, abundant, and relatively inexpensive fuel source for mostof the 20th century, its future in electric power generation is under increasing pressure as environmental regulations become morestringent worldwide. Current pollution control technologies for combustion exhaust gas generally treat the release of regulatedpollutants: sulfur dioxide, nitrogen oxides and particulate matter as three separate problems instead of as parts of one problem. Newand improved technologies have greatly reduced the emissions produced per ton of burning coal. The term “Clean Coal CombustionTechnology” applies generically to a range of technologies designed to greatly reduce the emissions from coal-fired power plants.The wet methods of desulfurization at present are the widest applied technology in professional energetics. This method is economicand gives good final results but a future for clean technologies is the biomass. Power from biomass is a proven commercial optionof the electricity generation in the World. An increasing number of power marketers are starting to offer environmentally friendlyelectricity, including biomass power, in response to the consumer demand and regulatory requirements.

  9. Residential gas-fired sorption heat pumps. Test and technology evaluation

    2008-12-15

    Heat pumps may be the next step in gas-fired residential space heating. Together with solar energy it is an option to combine natural gas and renewable energy. Heat pumps for residential space heating are likely to be based on the absorption or adsorption process, i.e. sorption heat pumps. Manufacturers claim that the efficiency could reach 140-160%. The annual efficiency will be lower but it is clear that gas-fired heat pumps can involve an efficiency and technology step equal to the transition from non-condensing gas boilers with atmospheric burners to condensing boilers. This report contains a review of the current sorption gas-fired heat pumps for residential space heating and also the visible development trends. A prototype heat pump has been laboratory tested. Field test results from Germany and the Netherlands are also used for a technology evaluation. The tested heat pump unit combines a small heat pump and a supplementary condensing gas boiler. Field tests show an average annual efficiency of 120% for this prototype design. The manufacturer abandoned the tested design during the project period and the current development concentrates on a heat pump design only comprising the heat pump, although larger. The heat pump development at three manufacturers in Germany indicates a commercial stage around 2010-2011. A fairly high electricity consumption compared to traditional condensing boilers was observed in the tested heat pump. Based on current prices for natural gas and electricity the cost savings were estimated to 12% and 27% for heat pumps with 120% and 150% annual efficiency respectively. There is currently no widespread performance testing procedure useful for annual efficiency calculations of gas-fired heat pumps. The situation seems to be clearer for electric compression heat pumps regarding proposed testing and calculation procedures. A German environmental label exists and gasfired sorption heat pumps are also slightly treated in the Eco-design work

    1998-01-01

    There are 1.3 million wood-burning fireplaces in Finnish homes. The interest in using fireplaces for heating of dwellings has recently been growing strongly. Some 5.6 million cubic meters of firewood is burned in domestic stoves and fireplaces annually. This corresponds to a total of 7.5 terawatthours of energy and amounts to 13 % of all energy used for heating in Finland. The aim of the TULISIJA research programme for wood firing technology (1997-1999) is to assist manufacturers in their efforts to develop the most emission-free, yet efficient, wood firing equipment in the world. Detailed objectives of the TULISIJA programme are: (1) To produce modelling capabilities for the evaluation of different fireplace designs. Capabilities are produced for utilising computer simulation for investigation of the emissions of small-size fireplaces. (2) To establish a measuring place for fireplaces, where manufacturers' equipment designs can be reliably tested according to different standards is to be built, through which the Finnish manufacturers may obtain approvals for their products for different market areas. (3) To enhance co-operation between manufacturers and research institutions. Within the programme, the expertise of researchers in universities and other research institutes is made available to manufacturers - and vice versa. Equally important is the utilisation of international co-operation and making new connections

    Available technology was surveyed as to possible application to more efficient gas-fired comfort heating and water heating in residences. Objectives were (1) to evaluate energy saving modifications and design approaches, including both retrofit and new systems, and (2) to identify RD and D required to bring to the marketplace those concepts that have a reasonable payback period. Over 60 concepts, including both retrofit devices and new designs, were identified on the basis of the study of the technical literature and discussions with various segments of industry. After evaluating each concept on the basis of expected initial cost, energy consumption, and operating cost, those concepts with a reasonably short payback period were considered from the point of view of RD and D needs. A principal recommendation covering several specific concepts was the study of condensing heat-exchanger systems. RD and D was recommended on both mechanical and aerodynamically valved pulse combustors, radiant burners, catalytic systems, heat pipe systems, self-powered heating units, and gas-fired heat pumps. Relative to retrofit concepts, recommendations covered the effects of derating on furnace corrosion and the methodology for predicting savings in individual homes. Need was also indicated for a methodology to optimize sizing of heating units and for data on energy demand requirements for integrated appliances. General recommendations related to systems control analysis, minimum venting requirements, and combustion air requirements in tight homes.

  12. Retired RNs: perceptions of volunteering.

    Cocca-Bates, Katherine C; Neal-Boylan, Leslie

    2011-01-01

    A qualitative study was done to explore the perceptions of volunteering among retired registered nurses (RNs) in Kansas. Participants were volunteers in formal nursing roles or were using their nursing knowledge and experience in non-nursing roles, such as church work. Regardless of the type of volunteer position, retired RNs reported that they use what they have learned as nurses when they volunteer. Volunteering benefits include enhanced self-worth, intellectual stimulation, reduced social isolation, and opportunities to help others. Increased paperwork, new technology, difficulty finding nursing-specific volunteer opportunities, resistance from health care organizations, and a lack of respect for what these nurses know are challenges and barriers to volunteering. Retired RNs have accumulated years of clinical nursing experience and can be helpful to employed nurses. Health care organizations should launch targeted efforts to recruit and utilize retired RN volunteers. Health care professionals who care for older adults should recommend volunteering as a healthful endeavor. Copyright © 2011 Mosby, Inc. All rights reserved.

    2010-08-01

    The electron beam treatment technology for purification of exhaust gases from the burning of heavy fuel oil (HFO) mazout with sulfur content approximately 3 wt % was tested at the Institute of Nuclear Chemistry and Technology laboratory plant. The parametric study was conducted to determine the sulfur dioxide (SO2), oxides of nitrogen (NO(x)), and polycyclic aromatic hydrocarbon (PAH) removal efficiency as a function of temperature and humidity of irradiated gases, absorbed irradiation dose, and ammonia stoichiometry process parameters. In the test performed under optimal conditions with an irradiation dose of 12.4 kGy, simultaneous removal efficiencies of approximately 98% for SO2, and 80% for NO(x) were recorded. The simultaneous decrease of PAH and one-ringed aromatic hydrocarbon (benzene, toluene, and xylenes [BTX]) concentrations was observed in the irradiated flue gas. Overall removal efficiencies of approximately 42% for PAHs and 86% for BTXs were achieved with an irradiation dose 5.3 kGy. The decomposition ratio of these compounds increased with an increase of absorbed dose. The decrease of PAH and BTX concentrations was followed by the increase of oxygen-containing aromatic hydrocarbon concentrations. The PAH and BTX decomposition process was initialized through the reaction with hydroxyl radicals that formed in the electron beam irradiated flue gas. Their decomposition process is based on similar principles as the primary reaction concerning SO2 and NO(x) removal; that is, free radicals attack organic compound chains or rings, causing volatile organic compound decomposition. Thus, the electron beam flue gas treatment (EBFGT) technology ensures simultaneous removal of acid (SO2 and NO(x)) and organic (PAH and BTX) pollutants from flue gas emitted from burning of HFO. This technology is a multipollutant emission control technology that can be applied for treatment of flue gas emitted from coal-, lignite-, and HFO-fired boilers. Other thermal processes such

    A set of 13 US based experts in post-combustion and oxy-fuel combustion CO 2 capture systems responded to an extensive questionnaire asking their views on the present status and future expected performance and costs for amine-based, chilled ammonia, and oxy-combustion retrofits of coal-fired power plants. This paper presents the experts' responses for technology maturity, ideal plant characteristics for early adopters, and the extent to which R and D and deployment incentives will impact costs. It also presents the best estimates and 95% confidence limits of the energy penalties associated with amine-based systems. The results show a general consensus that amine-based systems are closer to commercial application, but potential for improving performance and lowering costs is limited; chilled ammonia and oxy-combustion offer greater potential for cost reductions, but not without greater uncertainty regarding scale and technical feasibility. - Highlights: → Study presents experts' views on CCS retrofit costs and performance. → Experts commented on amine-based systems, chilled ammonia, and oxy-fuel combustion. → Estimates of future energy penalty show uncertainty for the three technologies. → These estimates under an aggressive RD and D policy scenario narrow significantly. → The experts' judgments support the need for enhanced RD and D for post-combustion CCS.

    1994-01-01

    Vortec has successfully completed Phase 1 of the ``Innovative Fossil Fuel Fired Vitrification Technology for Soil Remediation`` program. The Combustion and Melting System (CMS) has processed 7000 pounds of material representative of contaminated soil that is found at DOE sites. The soil was spiked with Resource Conservation and Recovery Act (RCRA) metals surrogates, an organic contaminant, and a surrogate radionuclide. The samples taken during the tests confirmed that virtually all of the radionuclide was retained in the glass and that it did not leach to the environment-as confirmed by both ANS 16.1 and Toxicity Characteristic Leaching Procedure (TCLP) testing. The organic contaminant, anthracene, was destroyed during the test with a Destruction and Removal Efficiency (DRE) of at least 99.99%. RCRA metal surrogates, that were in the vitrified product, were retained and did not leach to the environment as confirmed by the TCLP testing. Semi-volatile RCRA metal surrogates were captured by the Air Pollution Control (APC) system, and data on the amount of metal oxide particulate and the chemical composition of the particulate were established for use in the Phase 2 APC subsystem design.

    2016-09-01

    Full Text Available The global atmospheric concentration of anthropogenic gases, such as carbon dioxide, has increased substantially over the past few decades due to the high level of industrialization and urbanization that is occurring in developing countries, like South Africa. This has escalated the challenges of global warming. In South Africa, carbon capture and storage (CCS from coal-fired power plants is attracting increasing attention as an alternative approach towards the mitigation of carbon dioxide emission. Therefore, innovative strategies and process optimization of CCS systems is essential in order to improve the process efficiency of this technology in South Africa. This review assesses the potential of CCS as an alternative approach to reducing the amount CO2 emitted from the South African coal-fired power plants. It examines the various CCS processes that could be used for capturing the emitted CO2. Finally, it proposes the use of new adsorbents that could be incorporated towards the improvement of CCS technology.

    There are many different statistical and empirical methods of forest fire danger use at present time. All systems have not physical basis. Last decade deterministic-probabilistic method is rapidly developed in Tomsk Polytechnic University. Forest sites classification is one way to estimate forest fire danger. We used this method in present work. Forest fire danger estimation depends on forest vegetation condition, forest fire retrospective, precipitation and air temperature. In fact, we use modified Nesterov Criterion. Lightning activity is under consideration as a high temperature source in present work. We use Web-GIS platform for program realization of this method. The program realization of the fire danger assessment system is the Web-oriented geoinformation system developed by the Django platform in the programming language Python. The GeoDjango framework was used for realization of cartographic functions. We suggest using of Terra/Aqua MODIS products for hot spot monitoring. Typical territory for forest fire danger estimation is Proletarskoe forestry of Kherson region (Ukraine).

    2010-09-13

    Volunteer computing projects (VCPs) have been set up by groups of scientists to recruit members of the public who are asked to donate spare capacity on their personal computers to the processing of scientific data or computationally intensive models. VCPs serve two purposes: to acquire significant computing capacity and to educate the public about science. A particular challenge for these scientists is the retention of volunteers as there is a very high drop-out rate. This paper develops recommendations for scientists and software engineers setting up or running VCPs regarding which strategies to pursue in order to improve volunteer retention rates. These recommendations are based on a qualitative study of volunteers in a VCP (climateprediction.net). A typology of volunteers has been developed, and three particularly important classes of volunteers are presented in this paper: for each type of volunteer, the particular benefits they offer to a project are described, and their motivations for continued participation in a VCP are identified and linked to particular strategies. In this way, those setting up a VCP can identify which types of volunteers they should be particularly keen to retain, and can then find recommendations to increase the retention rates of their target volunteers.

    Presents recommendations on fire fighting in underground black coal mines. Situation when fire center is located in the goaf area left after longwall mining is analyzed. Fire fighting operations are divided into three stages: 1. fire fighting in the initial stage (installation of additional methane degassing means such as pipelines and pumps, pumping water, fire extinguishing foams or powders into fire center, ventilation, determining composition of the air in fire center), 2. intensification of fire fighting (increasing efficiency of degassing and fire extinguishing, improving ventilation of zone affected by the fire), 3. stage three occurs when fire extinguishing operations have been successful and consists in complete separation of the fire zone from the rest of the mine and from the ventilation system (changes in composition of fire gases and air are determined by automated instruments, injection of carbon dioxide or other inert gases, continuous deatatssing of the separated fire zone). Recommendations are listed in a detailed table. (In Russian)

    Highlights: • Sizing of biomass fired cogeneration block is performed for existing heating plant. • Mathematical model for cogeneration block optimisation is presented. • Impact of financial support mechanisms on optimal solution is discussed. • Influence of short term variations of prices and support intensity is presented. • Different design parameters are suggested by economic and technical quality indices. - Abstract: The paper presents results of design parameters optimisation of a wood chips fired steam boiler based heat and power block in a sample project of coal fired municipal heating plant modernisation. The project assumes the conversion of the heating plant into a dual fuel heat and power plant. The problem that is presented is selection of cogeneration block structure and thermodynamic parameters taking into account financial support mechanisms for cogeneration and renewable energy technologies. There are examined energy conversion and financial performances of the project. The results show that without the financial support the project is not profitable although it generates savings of primary energy of fossil fuels. If an administrative incentives are applied the optimal technical solution is different than suggested by energy conversion efficiency or fossil fuel savings. Financial calculations were performed for Polish marked conditions in the years 2011 and 2014 showing the impact of relatively short term variations of prices and support intensity on optimal plant design parameters

The results confirm that students believe that we live in a society which his generally thought only to its own benefit; they think that volunteering can not solve the problems in society; that people do not have enough experience with volunteering and people do not have time to volunteering; volunteering is for young people; in their family and among friends, there are no volunteers; everyone could be volunteer only if that wishes; do not believe that volunteering is a waste of time and it helps in future career. The prevalent number of students, regardless of the Faculty which they belong, rarely volunteered in areas outside of sport. Results also shows that students from sport faculties have less experience in volunteering in sport than students from other faculties, but this difference is not dramatic.

    Full Text Available The article describes the technology of NOx emission abatement by SNCR method. The scope of research included CDF simulations as well as design and construction of the pilot plant and tests of NOx reduction by urea in the plant located in industrial pulverized-coal fired boiler. The key step of research was to determine the appropriate temperature window for the SNCR process. The proposed solution of the location of injection lances in the combustion chamber enabled to achieve over a 30% reduction of NOx. It is possible to achieve higher effectiveness of the proposed SNCR technology and meet the required emission standards via providing prior reduction of NOx to the level of 350 mg/um3 using the primary methods.

    The Proposed New Environmental Quality (Clean Air) Regulation 201X (Draft), which replaces the Malaysia Environmental Quality (Clean Air) 1978, specifies limits to additional pollutants from power generation using fossil fuel. The new pollutants include Hg, HCl, and HF with limits of 0.03, 100, and 15 mg/N-m3 at 6% O2, respectively. These pollutants are normally present in very small concentrations (known as trace elements [TEs]), and hence are often neglected in environmental air quality monitoring in Malaysia. Following the enactment of the new regulation, it is now imperative to understand the TEs behavior and to assess the capability of the existing abatement technologies to comply with the new emission limits. This paper presents the comparison of TEs behavior of the most volatile (Hg, Cl, F) and less volatile (As, Be, Cd, Cr, Ni, Se, Pb) elements in subbituminous and bituminous coal and coal combustion products (CCP) (i.e., fly ash and bottom ash) from separate firing of subbituminous and bituminous coal in a coal-fired power plant in Malaysia. The effect of air pollution control devices configuration in removal of TEs was also investigated to evaluate the effectiveness of abatement technologies used in the plant. This study showed that subbituminous and bituminous coals and their CCPs have different TEs behavior. It is speculated that ash content could be a factor for such diverse behavior In addition, the type of coal and the concentrations of TEs in feed coal were to some extent influenced by the emission of TEs in flue gas. The electrostatic precipitator (ESP) and seawater flue gas desulfurization (FGD) used in the studied coal-fired power plant were found effective in removing TEs in particulate and vapor form, respectively, as well as complying with the new specified emission limits. Implications: Coals used by power plants in Peninsular Malaysia come from the same supplier (Tenaga Nasional Berhad Fuel Services), which is a subsidiary of the Malaysia

    Mercury (Hg) control technologies were evaluated at Minnkota Power Cooperative's Milton R. Young (MRY) Station Unit 2, a 450-MW lignite-fired cyclone unit near Center, North Dakota, and TXU Energy's Monticello Steam Electric Station (MoSES) Unit 3, a 793-MW lignite--Powder River Basin (PRB) subbituminous coal-fired unit near Mt. Pleasant, Texas. A cold-side electrostatic precipitator (ESP) and wet flue gas desulfurization (FGD) scrubber are used at MRY and MoSES for controlling particulate and sulfur dioxide (SO{sub 2}) emissions, respectively. Several approaches for significantly and cost-effectively oxidizing elemental mercury (Hg{sup 0}) in lignite combustion flue gases, followed by capture in an ESP and/or FGD scrubber were evaluated. The project team involved in performing the technical aspects of the project included Babcock & Wilcox, the Energy & Environmental Research Center (EERC), the Electric Power Research Institute, and URS Corporation. Calcium bromide (CaBr{sub 2}), calcium chloride (CaCl{sub 2}), magnesium chloride (MgCl{sub 2}), and a proprietary sorbent enhancement additive (SEA), hereafter referred to as SEA2, were added to the lignite feeds to enhance Hg capture in the ESP and/or wet FGD. In addition, powdered activated carbon (PAC) was injected upstream of the ESP at MRY Unit 2. The work involved establishing Hg concentrations and removal rates across existing ESP and FGD units, determining costs associated with a given Hg removal efficiency, quantifying the balance-of-plant impacts of the control technologies, and facilitating technology commercialization. The primary project goal was to achieve ESP-FGD Hg removal efficiencies of {ge}55% at MRY and MoSES for about a month.

    Many young people look forward to volunteering abroad and overlook the ample volunteer opportunities at home. There are several advantages to volunteering at home: you help people in your own community; you can make a long-term commitment; and you have continuity of care for your patients. There are >1200 free clinics in the United States whose main goal is to provide care to the indigent population. These free clinics are always looking for volunteers with specialized medical training. This article reviews the medically related and unrelated volunteer opportunities available in the United States. Volunteering at home is a worthwhile experience, and I encourage the otolaryngology community to explore these opportunities. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

  1. Latest heat sensing technology for real-time detection of endogenic fires

    Energy Technology Data Exchange (ETDEWEB)

    Makarius, R. (Cesky Bansky Urad, Prague (Czechoslovakia))

    1989-04-01

    Briefly discusses problem of endogenic fires in coal mines and describes principles used in design of modern heat sensors that record intensity of electromagnetic radiation emitted by the body in question (e.g. coal mass) and compare this with radiation from an ideal blackbody. Mentions Raytek-Raynger R-38, R-45 and R-450 instruments, which are currently in use in the Ostrava-Karvina, Kladno and Sokolov coalfields. Describes tests on a Swedish AGA 750 thermovision videocamera that is nitrogen cooled and produces thermograms from infrared radiation converted into electrical signals. It is powered either by 110-240 V 50 Hz mains electricity or by 12 V batteries and operates in 3-5.6 micrometer band. With the addition of special filters it can measure temperatures of up to 1600 C and has a resolution of 0.2 C for body temperatures of 30 C. Tests using an arch support in a 70 m section of a coal face as the body to be monitored showed that this instrument could detect even initial stages of self-ignition and give accurate location of mine fires. However, its sensitivity to mechanical shock means that it cannot be used in underground mining.

    Energy Technology Data Exchange (ETDEWEB)

    1993-08-17

    This report presents results from the third phase of an Innovative Clean Coal Technology (ICC-1) project demonstrating advanced tangentially-fired combustion techniques for the reduction of nitrogen oxide (NO{sub x}) emissions from a coal-fired boiler. The purpose of this project was to study the NO{sub x} emissions characteristics of ABB Combustion Engineering`s (ABB CE) Low NO{sub x} Concentric Firing System (LNCFS) Levels I, II, and III. These technologies were installed and tested in a stepwise fashion at Gulf Power Company`s Plant Lansing Smith Unit 2. The objective of this report is to provide the results from Phase III. During that phase, Levels I and III of the ABB C-E Services Low NO{sub x} Concentric Firing System were tested. The LNCFS Level III technology includes separated overfire air, close coupled overfire air, clustered coal nozzles, flame attachment coal nozzle tips, and concentric firing. The LNCFS Level I was simulated by closing the separated overfire air nozzles of the LNCFS Level III system. Based upon long-term data, LNCFS Level HI reduced NO{sub x} emissions by 45 percent at full load. LOI levels with LNCFS Level III increased slightly, however, tests showed that LOI levels with LNCFS Level III were highly dependent upon coal fineness. After correcting for leakage air through the separated overfire air system, the simulated LNCFS Level I reduced NO{sub x} emissions by 37 percent. There was no increase in LOI with LNCFS Level I.

    Full Text Available Nowadays, when the welfare state is a responsibility of the entire society, organizations in the private sector assume co-responsibility for social issues. They are also pressured by the challenges presented by technological advances and the globalization , involving new parameters and requirements for quality. In this context, the concept of Corporate Social Responsibility (RSC emerges as an option for solutions to the issues related to the company and the whole community. Among the actions of the RSC is the Corporate Volunteering-program, which aims to promote / encourage employes to do voluntary work. A central issue when talking about volunteering is the withdrawal of these (SILVA and FEITOSA, 2002; TEODÓSIO, 1999 and, in accordance with the Community Solidarity (1997, one of the possible causes for the withdrawal is the lack of clarity as to the motives and expectations that lead the person to volunteer themselves. This study uses qualitative research and triangulation of feedback from volunteers, coordinators of volunteers and social organizations, to present a framework from which it is possible to analyze the various motivations for the volunteer work. Key words: Corporate Volunteering program. Volunteering. Corporate social responsibility.

    The Energy & Environmental Research Center (EERC) is conducting a consortium-based effort directed toward resolving the mercury (Hg) control issues facing the lignite industry. Specifically, the EERC team--the EERC, EPRI, URS, ADA-ES, Babcock & Wilcox, the North Dakota Industrial Commission, SaskPower, and the Mercury Task Force, which includes Basin Electric Power Cooperative, Otter Tail Power Company, Great River Energy, Texas Utilities (TXU), Montana-Dakota Utilities Co., Minnkota Power Cooperative, BNI Coal Ltd., Dakota Westmoreland Corporation, and the North American Coal Company--has undertaken a project to significantly and cost-effectively oxidize elemental mercury in lignite combustion gases, followed by capture in a wet scrubber. This approach will be applicable to virtually every lignite utility in the United States and Canada and potentially impact subbituminous utilities. The oxidation process is proven at the pilot-scale and in short-term full-scale tests. Additional optimization is continuing on oxidation technologies, and this project focuses on longer-term full-scale testing. The lignite industry has been proactive in advancing the understanding of and identifying control options for Hg in lignite combustion flue gases. Approximately 1 year ago, the EERC and EPRI began a series of Hg-related discussions with the Mercury Task Force as well as utilities firing Texas and Saskatchewan lignites. This project is one of three being undertaken by the consortium to perform large-scale Hg control technology testing to address the specific needs and challenges to be met in controlling Hg from lignite-fired power plants. This project involves Hg oxidation upstream of a system equipped with an electrostatic precipitator (ESP) followed by wet flue gas desulfurization (FGD). The team involved in conducting the technical aspects of the project includes the EERC, Babcock & Wilcox, URS, and ADA-ES. The host sites include Minnkota Power Cooperative Milton R. Young

    An engineer and a computer expert from Goddard Space Flight Center were assigned to provide technical assistance in the design and installation of a computer assisted system for dispatching and communicating with fire department personnel and equipment in Baltimore City. Primary contributions were in decision making and management processes. The project is analyzed from four perspectives: (1) fire service; (2) technology transfer; (3) public administration; and (5) innovation. The city benefitted substantially from the approach and competence of the NASA personnel. Given the proper conditions, there are distinct advantages in having a nearby Federal laboratory provide assistance to a city on a continuing basis, as is done in the Baltimore Applications Project.

    A new paradigm is proposed for alleviating the chronic problem of inadequate response to natural and man-made disasters. Fundamental flaws and weaknesses in the current disaster mitigation system point to the need for an international consortium involving governments, academia, industry, and businesses. Recent changes in social and political framework offer a unique opportunity of rethink and reform the existing disaster response mechanism. Benefits of a collaborative consortium approach may include commercial incentives, improved cost effectiveness, coherence in research and development efforts, conduciveness for long-term planning, and improved deployment of technology for disaster mitigation.

    1998-01-01

    This report presents the results of a U.S. Department of Energy (DOE) Innovative Clean Coal Technology (ICCT) project demonstrating advanced wall-fired combustion techniques for the reduction of nitrogen oxide (NOx) emissions from coal-fired boilers. The project was conducted at Georgia Power Company`s Plant Hammond Unit 4 located near Rome, Georgia. The technologies demonstrated at this site include Foster Wheeler Energy Corporation`s advanced overfire air system and Controlled Flow/Split Flame low NOx burner. The primary objective of the demonstration at Hammond Unit 4 was to determine the long-term effects of commercially available wall-fired low NOx combustion technologies on NOx emissions and boiler performance. Short-term tests of each technology were also performed to provide engineering information about emissions and performance trends. A target of achieving fifty percent NOx reduction using combustion modifications was established for the project. Short-term and long-term baseline testing was conducted in an {open_quotes}as-found{close_quotes} condition from November 1989 through March 1990. Following retrofit of the AOFA system during a four-week outage in spring 1990, the AOFA configuration was tested from August 1990 through March 1991. The FWEC CF/SF low NOx burners were then installed during a seven-week outage starting on March 8, 1991 and continuing to May 5, 1991. Following optimization of the LNBs and ancillary combustion equipment by FWEC personnel, LNB testing commenced during July 1991 and continued until January 1992. Testing in the LNB+AOFA configuration was completed during August 1993. This report provides documentation on the design criteria used in the performance of this project as it pertains to the scope involved with the low NOx burners and advanced overfire systems.

    Various advanced energy conversion systems (ECS) are compared with each other and with current technology systems for their savings in fuel energy, costs, and emissions in individual plants and on a national level. About fifty industrial processes from the largest energy consuming sectors were used as a basis for matching a similar number of energy conversion systems that are considered as candidates which can be made available by the 1985 to 2000 time period. The sectors considered included food, textiles, lumber, paper, chemicals, petroleum, glass, and primary metals. The energy conversion systems included steam and gas turbines, diesels, thermionics, stirling, closed cycle and steam injected gas turbines, and fuel cells. Fuels considered were coal, both coal and petroleum based residual and distillate liquid fuels, and low Btu gas obtained through the on-site gasification of coal. Computer generated reports of the fuel consumption and savings, capital costs, economics and emissions of the cogeneration energy conversion systems (ECS's) heat and power matched to the individual industrial processes are presented for coal fired process boilers. National fuel and emissions savings are also reported for each ECS assuming it alone is implemented.

  1. Volunteered Cloud Computing for Disaster Management

    Science.gov (United States)

    Evans, J. D.; Hao, W.; Chettri, S. R.

    2014-12-01

    Disaster management relies increasingly on interpreting earth observations and running numerical models; which require significant computing capacity - usually on short notice and at irregular intervals. Peak computing demand during event detection, hazard assessment, or incident response may exceed agency budgets; however some of it can be met through volunteered computing, which distributes subtasks to participating computers via the Internet. This approach has enabled large projects in mathematics, basic science, and climate research to harness the slack computing capacity of thousands of desktop computers. This capacity is likely to diminish as desktops give way to battery-powered mobile devices (laptops, smartphones, tablets) in the consumer market; but as cloud computing becomes commonplace, it may offer significant slack capacity -- if its users are given an easy, trustworthy mechanism for participating. Such a "volunteered cloud computing" mechanism would also offer several advantages over traditional volunteered computing: tasks distributed within a cloud have fewer bandwidth limitations; granular billing mechanisms allow small slices of "interstitial" computing at no marginal cost; and virtual storage volumes allow in-depth, reversible machine reconfiguration. Volunteered cloud computing is especially suitable for "embarrassingly parallel" tasks, including ones requiring large data volumes: examples in disaster management include near-real-time image interpretation, pattern / trend detection, or large model ensembles. In the context of a major disaster, we estimate that cloud users (if suitably informed) might volunteer hundreds to thousands of CPU cores across a large provider such as Amazon Web Services. To explore this potential, we are building a volunteered cloud computing platform and targeting it to a disaster management context. Using a lightweight, fault-tolerant network protocol, this platform helps cloud users join parallel computing projects

  2. Motivations of German Hospice Volunteers: How Do They Compare to Nonhospice Volunteers and US Hospice Volunteers?

    Science.gov (United States)

    Stelzer, Eva-Maria; Lang, Frieder R

    2016-03-01

    We examined reasons of volunteering for hospice and nonhospice organizations in a study with 125 volunteers (22-93 years) from the United States and Germany. Motives of US and German hospice volunteers revealed similarities and few differences. Hospice volunteers are involved because they seek to help others, seek new learning experiences, seek social contacts, or seek personal growth. The US hospice volunteers reported motives related to altruistic concerns, enhancement, and social influence as more influential, while German hospice volunteers rated career expectations as being more important. Comparison of German hospice with nonhospice volunteers revealed stronger differences: German hospice volunteers scored higher on altruistic motives, while German nonhospice volunteers yielded higher scores on self-serving motives. Findings contribute to improved understanding of volunteering motivation and of activating or retaining hospice volunteers. © The Author(s) 2014.

    Full Text Available As the human technology moved further, the risk of natural and man induced sudden damage increase exponentially. One of the most dangerous disasters is fire. In addition to its direct danger on human's lives, fire consumes forests where trees that provide humans with oxygen are destroyed. Every year, the large number of wildfires happening all over the world they burn forested lands, causing adverse ecological and social impacts. Early warning and immediate responses are the only ways to avoid such type of disasters. This work describes a naïve method is used to detect flames in forest by using a Spatio Wildfire Prediction and Monitoring System (SWPMS. Basically, the fired information retrieving from regions by using background subtraction and colour analysis. The fire behaviour is modelled by texture analysis using computer vision systems. The Central Server should receives fired regions from the volunteer's smart phone and use fired location coordinates, different angles of smart phone receives fired locations based on Google Earth API. Finally, Kalman filter estimator computes the position vector of a moving object. Antennas or Satellite systems are grasping information from fire regions then GIS will be analyzed those regions and send alert to local peoples of forest regions and NDRF team.

    Ceramic finds from the Inka workshops at Tambo Real and La Viña in the Leche Valley in northern Peru were studied by Mössbauer spectroscopy, thin section microscopy and X-ray diffraction. Sherds of Inka style vessels and of local style vessels can be distinguished by their shape, although local techniques appear to have been used in making both types. A reconstruction of the firing techniques by scientific studies of the ceramic material does not reveal a substantial difference in material or in the firing of both forms, although high firing temperatures were necessary to achieve sufficient stability of the large Inka style vessels. It cannot be decided whether the smaller local vessels were fired together with the Inka vessels or separately. Most of the variation in the maximum firing temperature can be explained with the normal temperature and atmosphere fluctuations in an open pit kiln.

A reconstruction of the firing techniques by scientific studies of the ceramic material does not reveal a substantial difference in material or in the firing of both forms, although high firing temperatures were necessary to achieve sufficient stability of the large Inka style vessels. It cannot be decided whether the smaller local vessels were fired together with the Inka vessels or separately. Most of the variation in the maximum firing temperature can be explained with the normal temperature and atmosphere fluctuations in an open pit kiln.

    Optimization experiment of SCR denitrification technologies on a 300MW unit was conducted. Adjustment of ammonia injection quantity of corresponding AIG was conducted after measuring the SCR export NOx concentration field in 250MW load, the distribution uniformity of NOx volume fraction at the outlet of both reactor A and B was improved significantly, where the relative standard deviation of NOx reduced respectively from 29.83% to 13.01% and 24.54% to 9.26%, simultaneously, the amount of ammonia escape of A, B reactor decrease respectively by 24.76%, 19.45%. The results of optimization experiment show that, optimal adjustment can improve the NOx concentration distribution, reduce the amount of ammonia escape in a certain extent, and judge whether the catalytic activity of the regional catalyzer is in good condition. As to the area where catalyst is ineffective, the effect of optimization experiment is limited, the catalyzer should be the timely replacement, so as to better protect downstream equipment.

    Ceramics have a long history in fixed prosthodontics for achieving optimal esthetics and various materials have been used to improve ceramic core strength. However, there is a lack of information on how color is affected by fabrication procedure. The purpose of this study was to evaluate the effects of various dentin ceramic thicknesses and repeated firings on the color of zirconium oxide all-ceramic system (Lava™) fabricated using CAD/CAM technology. Thirty disc-shaped cores, 12 mm in diameter with a 1 mm thickness were fabricated from zirconium oxide based all ceramic systems (Lava™, 3M ESPE, St Paul, MN, USA) and divided into three groups (n = 10) according to veneering with dentin ceramic thicknesses: as 0.5, 1, or 1.5 mm. Repeated firings (3, 5, 7, or 9) were performed, and the color of the specimens was compared with the color after the initial firing. Color differences among ceramic specimens were measured using a spectrophotometer (VITA Easyshade, VITA Zahnfabrik, Bad Säckingen, Germany) and data were expressed in CIELAB system coordinates. A repeated measures ANOVA and Bonferroni post hoc test were used to analyze the data (n = 10, α=.05). L*a*b* values of the ceramic systems were affected by the number of firings (3, 5, 7, or 9 firings) (PL*a*b* values between the number of firings and ceramic thickness (P<.001). An increase in number of firings resulted in significant increase in L* values for both 0.5 mm and 1.5 mm thicknesses (P<.01, P=.013); however it decreased for 1 mm thickness (P<.01). The a* values increased for 1 mm and 1.5 mm thicknesses (P<.01), while it decreased for 0.5 mm specimens. The b* values increased significantly for all thicknesses (P<.01, P=.022). As the dentin ceramic thickness increased, significant reductions in L* values (P<.01) were recorded. There were significant increases in both a* and b* values (P<.01) as the dentin ceramic thickness increased. The number of firings and dentin ceramic thickness have a definite

    2011-07-31

    Through a U.S. Department of Energy (DOE) National Energy Technology Laboratory (NETL) funded cooperative agreement DE-NT0005649, ADA Environmental Solutions (ADA) has begun evaluating the use of solid sorbents for CO{sub 2} capture. The project objective was to address the viability and accelerate development of a solid-based CO{sub 2} capture technology. To meet this objective, initial evaluations of sorbents and the process / equipment were completed. First the sorbents were evaluated using a temperature swing adsorption process at the laboratory scale in a fixed-bed apparatus. A slipstream reactor designed to treat flue gas produced by coal-fired generation of nominally 1 kWe was designed and constructed, which was used to evaluate the most promising materials on a more meaningful scale using actual flue gas. In a concurrent effort, commercial-scale processes and equipment options were also evaluated for their applicability to sorbent-based CO{sub 2} capture. A cost analysis was completed that can be used to direct future technology development efforts. ADA completed an extensive sorbent screening program funded primarily through this project, DOE NETL cooperative agreement DE-NT0005649, with support from the Electric Power Research Institute (EPRI) and other industry participants. Laboratory screening tests were completed on simulated and actual flue gas using simulated flue gas and an automated fixed bed system. The following types and quantities of sorbents were evaluated: 87 supported amines, 31 carbon based materials, 6 zeolites, 7 supported carbonates (evaluated under separate funding), 10 hydrotalcites. Sorbent evaluations were conducted to characterize materials and down-select promising candidates for further testing at the slipstream scale. More than half of the materials evaluated during this program were supported amines. Based on the laboratory screening four supported amine sorbents were selected for evaluation at the 1 kW scale at two different

  18. Current trends towards a new regulation and evolution of fire protection systems technologies in nuclear power plants

    International Nuclear Information System (INIS)

    Rodriguez Sanjuan, G.

    1996-01-01

    For some time now, the field of Fire Protection in Nuclear Power Plants has, with its own peculiarities in an otherwise general process, been the centre of some controversy caused by tendencies to reduce regulatory inflexibility by transforming what was originally a prescriptive, pro grammatical and deterministic regulatory system into a system based on risk assessment and operating experience. Such tendencies include: Cost Beneficial Licensing Actions (CBLA) Use of the Probabilistic Safety Analysis (PSA) as a tool for evaluating the impact of postulated fires in nuclear safety Improvement of communications between the regulatory body and the industry These trends have coincided with the arduous process of requalifying passive fire-resistant protection materials, such as Thermo lag and others, which are used to separate redundant Safe Shutdown trains with fire-resistance ranges of one (1) hour or three (3) hours, in compliance with some of the alternatives that Appendix R to 10 CFR 50 offers. The process has involved a lot of effort and financial cost in requalification and in employing compensatory measures until operability of the fire-resistant materials is reestablished. A new test methodology has been created for these barriers (GL 86-10, Supplement 1) and new materials have become available and are currently undergoing qualification. (Author)

    Six facilities, representing the scope of different co-firing techniques with their associated RDF production systems were reviewed in detail for combustion equipment, firing modes, emission control systems, residue handling/disposal, and effluent wastewater treatment. These facilities encompass all currently operational or soon to be operational co-firing plants and associated RDF production systems. Occupational health and safety risks for these plants were evaluated on the basis of fatal and nonfatal accidents and disease arising from the respective fuel cycles, coal and RDF. Occupational risks include exposure to pathogenic organisms in the workplace. Unusual events that are life threatening in the RDF processing industry (e.g., explosions) are also discussed and remedial and safety measures reviewed. 80 refs., 4 figs., 30 tabs.

    Vortex has successfully completed Phase 1 of the ``Innovative Fossil Fuel Fired Vitrification Technology for Soil Remediation`` program with the Department of Energy (DOE) Morgantown Energy Technology Center (METC). The Combustion and Melting System (CMS) has processed 7000 pounds of material representative of contaminated soil that is found at DOE sites. The soil was spiked with Resource Conversation and Recovery Act (RCRA) metals surrogates, an organic contaminant, and a surrogate radionuclide. The samples taken during the tests confirmed that virtually all of the radionuclide was retained in the glass and that it did not leach to the environment. The organic contaminant, anthracene, was destroyed during the test with a Destruction and Removal Efficiency (DRE) of at least 99.99%. RCRA metal surrogates, that were in the vitrified product, were retained and will not leach to the environment--as confirmed by the TCLP testing. Semi-volatile RCRA metal surrogates were captured by the Air Pollution Control (APC) system, and data on the amount of metal oxide particulate and the chemical composition of the particulate were established for use in the Phase 2 APC system design. This topical report will present a summary of the activities conducted during Phase 1 of the ``Innovative Fossil Fuel Fired Vitrification Technology for Soil Remediation`` program. The report includes the detail technical data generated during the experimental program and the design and cost data for the preliminary Phase 2 plant.

    The involvement of non-government organizations (NGOs) and support groups has helped strengthen public health services in addressing cancer care burden. Owing to the contribution of volunteers in cancer care, this article documents a qualitative study that examined challenges in attracting and retaining cancer care volunteers as part of the effort to develop a volunteer recruitment model. Data were collected through three focus group discussions involving 19 cancer support group members in Malaysia. Findings of the study revealed that mobility and locality appeared to be significant in Malaysian context, while the need for financial support and time flexibility are challenges faced by cancer support groups to attract and retain volunteers. The findings imply that cancer care initiatives can benefit from more local volunteers but at the same time these volunteers require flexibility and financial support to sustain their engagement.

    The annual peat fire disasters have suffered human life, deteriorated peat land ecosystems, and caused severe economic losses in Indonesia, Malaysia, Brunei, and Singapore during a period of 2014-2016. The objective of this study is to investigate to what extent the weather modification technology (WMT) may play its roles in increasing the precipitation rates in order to mitigate the peat fires disaster in Bengkalis, Riau Province, Indonesia. The study obtained the precipitation rates data from the tropical rainfall measuring mission (TRMM) satellite during the period of 2014, 2015 and 2016. The data then statistically analyzed using the Grads software package. While the process of WMT at the designated research location was evaluated together between the Artificial Rain Unit of BPPT (Agency for the Assessment and Application Technology), and the Engineering Faculty, University of Riau, 2016. The research showed that the WMT increased the rainfall rates during the dry season within the study area by 8% (520.7 mm to 557 mm) in the 3 months period (July 14 -October 6, 2016), and reducing significantly hotspots by 88.6% from 6.725 in 2014 to 770 in 2016. Hence, it confirmed that the application of technical WMT procedures may increase precipitation rates and reduce the number of hot spots in Bengkalis.

    Gomberg, A.

    There was considerable progress made on several fronts of fire investigation in the United States in recent years. Progress was made in increasing the quantity of fire investigation and reporting, through efforts to develop the National Fire Incident Reporting System. Improving overall quality of fire investigation is the objective of efforts such as the Fire Investigation Handbook, which was developed and published by the National Bureau of Standards, and the upgrading and expanding of the ""dictionary'' of fire investigation and reporting, the NFPA 901, Uniform Coding for Fire Protection, system. The science of fire investigation as furthered also by new approaches to post fire interviews being developed at the University of Washington, and by in-depth research into factors involved in several large loss fires, including the MGM Grand Hotel in Las Vegas. Finally, the use of special study fire investigations - in-depth investigations concentrating on specific fire problems - is producing new glimpses into the nature of the national fire problem. A brief description of the status of efforts in each of these areas is discussed.

    Next-generation sequencing (NGS) is commonly used for researching the causes of genetic disorders. However, its usefulness in clinical practice for medical diagnosis is in early development. In this report, we demonstrate the value of NGS for genetic risk assessment and evaluate the limitations and barriers for the adoption of this technology into medical practice. We performed whole exome sequencing (WES) on 81 volunteers, and for each volunteer, we requested personal medical histories, constructed a three-generation pedigree, and required their participation in a comprehensive educational program. We limited our clinical reporting to disease risks based on only rare damaging mutations and known pathogenic variations in genes previously reported to be associated with human disorders. We identified 271 recessive risk alleles (214 genes), 126 dominant risk alleles (101 genes), and 3 X-recessive risk alleles (3 genes). We linked personal disease histories with causative disease genes in 18 volunteers. Furthermore, by incorporating family histories into our genetic analyses, we identified an additional five heritable diseases. Traditional genetic counseling and disease education were provided in verbal and written reports to all volunteers. Our report demonstrates that when genome results are carefully interpreted and integrated with an individual's medical records and pedigree data, NGS is a valuable diagnostic tool for genetic disease risk.

    2001-01-01

    The project represents a landmark assessment of the potential of low-NO(sub x) burners, advanced overtire air, and neural-network control systems to reduce NO(sub x) emissions within the bounds of acceptable dry-bottom, wall-fired boiler performance. Such boilers were targeted under the Clean Air Act Amendments of 1990 (CAAA). Testing provided valuable input to the Environmental Protection Agency ruling issued in March 1994, which set NO(sub x) emission limits for ''Group 1'' wall-fired boilers at 0.5 lb/10(sup 6) Btu to be met by January 1996. The resultant comprehensive database served to assist utilities in effectively implementing CAAA compliance. The project is part of the U.S. Department of Energy's Clean Coal Technology Demonstration Program established to address energy and environmental concerns related to coal use. Five nationally competed solicitations sought cost-shared partnerships with industry to accelerate commercialization of the most advanced coal-based power generation and pollution control technologies. The Program, valued at over$5 billion, has leveraged federal funding twofold through the resultant partnerships encompassing utilities, technology developers, state governments, and research organizations. This project was one of 16 selected in May 1988 from 55 proposals submitted in response to the Program's second solicitation. Southern Company Services, Inc. (SCS) conducted a comprehensive evaluation of the effects of Foster Wheeler Energy Corporation's (FWEC) advanced overfire air (AOFA), low-NO(sub x) burners (LNB), and LNB/AOFA on wall-fired boiler NO(sub x) emissions and other combustion parameters. SCS also evaluated the effectiveness of an advanced on-line optimization system, the Generic NO(sub x) Control Intelligent System (GNOCIS). Over a six-year period, SCS carried out testing at Georgia Power Company's 500-MWe Plant Hammond Unit 4 in Coosa, Georgia.

    Computing for the LHC, and for HEP more generally, is traditionally viewed as requiring specialized infrastructure and software environments, and therefore not compatible with the recent trend in "volunteer computing", where volunteers supply free processing time on ordinary PCs and laptops via standard Internet connections. In this paper, we demonstrate that with the use of virtual machine technology, at least some standard LHC computing tasks can be tackled with volunteer computing resources. Specifically, by presenting volunteer computing resources to HEP scientists as a "volunteer cloud", essentially identical to a Grid or dedicated cluster from a job submission perspective, LHC simulations can be processed effectively. This article outlines both the technical steps required for such a solution and the implications for LHC computing as well as for LHC public outreach and for participation by scientists from developing regions in LHC research.

    Energy Technology Data Exchange (ETDEWEB)

    1977-12-01

    An NOx control technology assessment study was conducted to examine the effectiveness of low-excess-air firing, staged combustion, flue gas recirculation, and current burner/boiler designs as applied to coal-fired utility boilers. Significant variations in NOx emissions exist with boiler type, firing method, and coal type, but a relative comparison of emissions control performance, cost, and operational considerations is presented for each method. The study emphasized the numerous operational factors that are of major importance to the user in selecting and implementing a combustion modification technique. Staged combustion and low-excess-air operation were identified as the most cost-effective methods for existing units. Close control of local air/fuel ratios and rigorous combustion equipment maintenance are essential to the success of both methods. Flue gas recirculation is relatively ineffective and has the added concern of tube erosion. More research is needed to resolve potential corrosion concerns with low-NOx operating modes. Low-NOx burners in conjunction with a compartmentalized windbox are capable of meeting a 0.6-lb/million Btu emission level on new units. Advanced burner designs are being developed to meet research emission goals of approximately 0.25 lb/MBtu.

  19. Grandparenting Roles and Volunteer Activity.

    Bulanda, Jennifer Roebuck; Jendrek, Margaret Platt

    2016-01-01

    We examine whether grandparenting roles are related to formal volunteering among older adults. Logistic regression is used to examine the likelihood of volunteering based on grandchild care using data from the 2004 wave of the Health and Retirement Study (n = 13,785). Longitudinal analyses utilize treatment effects models to examine changes in volunteering for grandparents who begin nonresidential grandchild care between the 2004 and 2008 waves (n = 10,811). Results show that grandparents raising coresidential grandchildren have lower odds of volunteering than grandparents providing no regular grandchild care. However, grandparents who provide nonresidential grandchild care are more likely to volunteer than grandparents not providing grandchild care and those raising a coresidential grandchild. Grandparents who provide nonresidential care for grandchildren engage in more volunteering before assuming grandchild care, and their volunteerism increases after becoming a caregiver for a grandchild. Consistent with resource theory and the accumulation of roles, providing nonresidential grandchild care may draw grandparents into formal volunteer activity. The lower human capital resources evidenced by grandparents raising coresidential grandchildren may play a role in their lower likelihood of formal volunteering. © The Author 2014.

  1. Slipstream pilot-scale demonstration of a novel amine-based post-combustion technology for carbon dioxide capture from coal-fired power plant flue gas

    Energy Technology Data Exchange (ETDEWEB)

    Krishnamurthy, Krish R. [Linde LLC, Murray Hill, NJ (United States)

    2017-02-03

    Post-combustion CO2 capture (PCC) technology offers flexibility to treat the flue gas from both existing and new coal-fired power plants and can be applied to treat all or a portion of the flue gas. Solvent-based technologies are today the leading option for PCC from commercial coal-fired power plants as they have been applied in large-scale in other applications. Linde and BASF have been working together to develop and further improve a PCC process incorporating BASF’s novel aqueous amine-based solvent technology. This technology offers significant benefits compared to other solvent-based processes as it aims to reduce the regeneration energy requirements using novel solvents that are very stable under the coal-fired power plant feed gas conditions. BASF has developed the desired solvent based on the evaluation of a large number of candidates. In addition, long-term small pilot-scale testing of the BASF solvent has been performed on a lignite-fired flue gas. In coordination with BASF, Linde has evaluated a number of options for capital cost reduction in large engineered systems for solvent-based PCC technology. This report provides a summary of the work performed and results from a project supported by the US DOE (DE-FE0007453) for the pilot-scale demonstration of a Linde-BASF PCC technology using coal-fired power plant flue gas at a 1-1.5 MWe scale in Wilsonville, AL at the National Carbon Capture Center (NCCC). Following a project kick-off meeting in November 2011 and the conclusion of pilot plant design and engineering in February 2013, mechanical completion of the pilot plant was achieved in July 2014, and final commissioning activities were completed to enable start-up of operations in January 2015. Parametric tests were performed from January to December 2015 to determine optimal test conditions and evaluate process performance over a variety of operation parameters. A long-duration 1500-hour continuous test campaign was performed from May to

    1991-01-01

    This book examines the many complex and sensitive issues relating to wildland fires. Beginning with an overview of the fires of 1980s, the book discusses the implications of continued drought and considers the behavior of wildland fires, from ignition and spread to spotting and firestorms. Topics include the effects of weather, forest fuels, fire ecology, and the effects of fire on plants and animals. In addition, the book examines firefighting methods and equipment, including new minimum impact techniques and compressed air foam; prescribed burning; and steps that can be taken to protect individuals and human structures. A history of forest fire policies in the U.S. and a discussion of solutions to fire problems around the world completes the coverage. With one percent of the earth's surface burning every year in the last decade, this is a penetrating book on a subject of undeniable importance

    About fifty industrial processes from the largest energy consuming sectors were used as a basis for matching a similar number of energy conversion systems that are considered as candidate which can be made available by the 1985 to 2000 time period. The sectors considered included food, textiles, lumber, paper, chemicals, petroleum, glass, and primary metals. The energy conversion systems included steam and gas turbines, diesels, thermionics, stirling, closed cycle and steam injected gas turbines, and fuel cells. Fuels considered were coal, both coal and petroleum based residual and distillate liquid fuels, and low Btu gas obtained through the on site gasification of coal. Computer generated reports of the fuel consumption and savings, capital costs, economics and emissions of the cogeneration energy conversion systems (ECS's) heat and power matched to the individual industrial processes are presented. National fuel and emissions savings are also reported for each ECS assuming it alone is implemented. Two nocogeneration base cases are included: coal fired and residual fired process boilers.

  7. Innovative Clean Coal Technology (ICCT): Demonstration of selective catalytic reduction (SCR) technology for the control of nitrogen oxide (NO{sub x}) emissions from high-sulfur coal-fired boilers. Technical progress report, third and fourth quarters 1994

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    1995-11-01

    The objective of this project is to demonstrate and evaluate commercially available selective catalytic reduction (SCR) catalysts from U.S., Japanese, and European catalyst suppliers on a high-sulfur U.S. Coal-fired boiler. SCR is a post-combustion nitrogen oxide (NO{sub x}) control technology that involves injecting ammonia into the flue gas generated from coal combustion in an electric utility boiler. The flue gas containing ammonia is then passed through a reactor that contains a specialized catalyst. In the presence of the catalyst, the ammonia reacts with NO{sub x} to form nitrogen and water vapor. Although SCR is widely practiced in Japan and European gas-, oil-, and low-sulfur coal-fired boilers, there are several technical uncertainties associated with applying SCR to U.S. coals. These uncertainties include: (1) potential catalyst deactivation due to poisoning by trace metal species present in U.S. coals that are not present in other fuels; (2) performance of the technology and effects on the balance-of-plant equipment in the presence of high amounts of SO{sub 2} and SO{sub 3}; performance of a wide variety of SCR catalyst compositions, geometries, and methods of manufacture under typical high-sulfur coal-fired utility operating conditions. These uncertainties are being explored by operating a series of small- scale SCR reactors and simultaneously exposing different SCR catalysts to flue gas derived from the combustion of high sulfur U.S. coal. The demonstration is being performed at Gulf Power Company`s Plant Crist Unit No. 5 (75 MW capacity) near Pensacola, Florida. The project is funded by the U.S. Department of Energy (DOE), Southern Company Services, Inc. (SCS on behalf of the entire Southern electric system), the Electric Power Research Institute (EPRI), and Ontario Hydro. SCS is the participant responsible for managing al aspects of this project. 1 ref., 69 figs., 45 tabs.

  9. Microfabrication of a Novel Ceramic Pressure Sensor with High Sensitivity Based on Low-Temperature Co-Fired Ceramic (LTCC Technology

    Directory of Open Access Journals (Sweden)

    Chen Li

    2014-06-01

    Full Text Available In this paper, a novel capacitance pressure sensor based on Low-Temperature Co-Fired Ceramic (LTCC technology is proposed for pressure measurement. This approach differs from the traditional fabrication process for a LTCC pressure sensor because a 4J33 iron-nickel-cobalt alloy is applied to avoid the collapse of the cavity and to improve the performance of the sensor. Unlike the traditional LTCC sensor, the sensitive membrane of the proposed sensor is very flat, and the deformation of the sensitivity membrane is smaller. The proposed sensor also demonstrates a greater responsivity, which reaches as high as 13 kHz/kPa in range of 0–100 kPa. During experiments, the newly fabricated sensor, which is only about 6.5 cm2, demonstrated very good performance: the repeatability error, hysteresis error, and nonlinearity of the sensor are about 4.25%, 2.13%, and 1.77%, respectively.

    2003-03-11

    The U.S. Department of Energy (DOE) proposes to provide partial funding to the Sunflower Electric Power Corporation (Sunflower), to demonstrate the commercial application of Low-NO{sub x} Burner/Separated Over-Fire Air (LNB/SOFA) integration system to achieve NO{sub x} emission reduction to the level of 0.15 to 0.22 pounds per million British thermal units (lb/MM Btu). The proposed project station is Sunflower's 360 MW coal-fired generation station, Holcomb Unit No. 1 (Holcomb Station). The station, fueled by coal from Wyoming's Powder River Basin, is located near Garden City, in Finney County, Kansas. The period of performance is expected to last approximately 2 years. The Holcomb Station, Sunflower LNB/SOFA integrated system would be modified in three distinct phases to demonstrate the synergistic effect of layering NO{sub x} control technologies. Once modified, the station would demonstrate that a unit equipped with an existing low-NO{sub x} burner system can be retrofitted with a new separated over-fire air (SOFA) system, coal flow measurement and control, and enhanced combustion monitoring to achieve about 45 percent reduction in nitrogen oxides (NO{sub x}) emissions. The proposed project would demonstrate a technology alternative to Selective Catalytic Reduction (SCR) systems. While SCR does generally achieve high reductions in NO{sub x} emissions (from about 0.8 lb/MM to 0.12 lb/MM Btu), it does so at higher capital and operating cost, requires the extensive use of critical construction labor, requires longer periods of unit outage for deployment, and generally requires longer periods of time to complete shakedown and full-scale operation. Cost of the proposed project technology would be on the order of 15-25 percent of that for SCR, with consequential benefits derived from reductions in construction manpower requirements and periods of power outages. This proposed technology demonstration would generally be applicable to boilers using opposed

    Full Text Available This case study is based on the experiences with the Electronic Journal of Information Technology in Construction (ITcon, founded in 1995. This journal is an example of a particular category of open access journals, which use neither author charges nor subscriptions to finance their operations, but rely largely on unpaid voluntary work in the spirit of the open source movement. The journal has, after some initial struggle, survived its first decade and is now established as one of half-a-dozen peer reviewed journals in its field. The journal publishes articles as they become ready, but creates virtual issues through alerting messages to “subscribers”. It has also started to publish special issues, since this helps to attract submissions, and also helps in sharing the work-load of review management. From the start the journal adopted a rather traditional layout of the articles. After the first few years the HTML version was dropped and papers are only published in PDF format. The journal has recently been benchmarked against the competing journals in its field. Its acceptance rate of 53% is slightly higher and its average turnaround time of seven months almost a year faster compared to those journals in the sample for which data could be obtained. The server log files for the past three years have also been studied. Our overall experience demonstrates that it is possible to publish this type of OA journal, with a yearly publishing volume equal to a quarterly journal and involving the processing of some fifty submissions a year, using a networked volunteer-based organization.

  16. Fire protection for launch facilities using machine vision fire detection

    Science.gov (United States)

    Schwartz, Douglas B.

    1993-01-01

    Fire protection of critical space assets, including launch and fueling facilities and manned flight hardware, demands automatic sensors for continuous monitoring, and in certain high-threat areas, fast-reacting automatic suppression systems. Perhaps the most essential characteristic for these fire detection and suppression systems is high reliability; in other words, fire detectors should alarm only on actual fires and not be falsely activated by extraneous sources. Existing types of fire detectors have been greatly improved in the past decade; however, fundamental limitations of their method of operation leaves open a significant possibility of false alarms and restricts their usefulness. At the Civil Engineering Laboratory at Tyndall Air Force Base in Florida, a new type of fire detector is under development which 'sees' a fire visually, like a human being, and makes a reliable decision based on known visual characteristics of flames. Hardware prototypes of the Machine Vision (MV) Fire Detection System have undergone live fire tests and demonstrated extremely high accuracy in discriminating actual fires from false alarm sources. In fact, this technology promises to virtually eliminate false activations. This detector could be used to monitor fueling facilities, launch towers, clean rooms, and other high-value and high-risk areas. Applications can extend to space station and in-flight shuttle operations as well; fiber optics and remote camera heads enable the system to see around obstructed areas and crew compartments. The capability of the technology to distinguish fires means that fire detection can be provided even during maintenance operations, such as welding.

  19. Vocational guidance in social volunteering

    Directory of Open Access Journals (Sweden)

    Nikolay S. Pryazhnikov

    2017-03-01

    Full Text Available The paper discusses the possibilities and limitations of vocational guidance in the social volunteering system. The essence of volunteer work is closely related with assistance to desperate people in searching for the meaning of living, often coinciding with labour activity that are deemed in terms of “the main matter of life” and “the leading activity”. For adolescents, it is the choice of career, and for adults, it is the work proper (i.e. an essential condition for personal self-realization. The problem of “forced volunteering” for experts in vocational guidance also means that they often have to work voluntarily and unselfishly outside the official guidelines. To clarify the terms «volunteer» and «a person in desperate need of help» the study used the method of analyzing the documents, e.g. the Regulations on Social Volunteering, the generalization of psychological sources, the initial survey of university students as active supporters of the volunteer movement, On the essence of volunteering and the place of career guidance in selfless social work. Vocational guidance is not excluded from the general system of volunteerism, but has an insufficiently defined status and low popularity among participants in social volunteering. Also, the problem of «forced volunteering» of experts in career counseling, which often requires voluntary and unselfish performance of quality work outside the framework of official instructions, is also indicated. Simultaneously, positive aspects of such disinterested career initiatives are noted, in particular, less control by the official inspectors (or customers and, accordingly, greater freedom of creativity than when someone else does the work.

  2. Assessment of energy and economic impacts of particulate-control technologies in coal-fired power generation

    Energy Technology Data Exchange (ETDEWEB)

    1980-04-01

    Under contract to Argonne National Laboratory, Midwest Research Institute has derived models to assess the economic and energy impacts of particulate-control systems for coal-fired power plants. The models take into account the major functional variables, including plant size and location, coal type, and applicable particulate-emission standards. The algorithms obtained predict equipment and installation costs, as well as operating costs (including energy usage), for five control devices: (1) cold-side electrostatic precipitators, (2) hot-side electrostatic precipitators, (3) reverse-flow baghouses, (4) shake baghouses, and (5) wet scrubbers. A steam-generator performance model has been developed, and the output from this model has been used as input for the control-device performance models that specify required design and operating parameters for the control systems under study. These parameters then have been used as inputs to the cost models. Suitable guideline values have been provided for independent variables wherever necessary, and three case studies are presented to demonstrate application of the subject models. The control-equipment models aggregate the following cost items: (1) first costs (capital investment), (2) total, first-year annualized costs, and (3) integrated cost of ownership and operation over any selected plant lifetime. Although the models have been programmed for rapid computation, the algorithms can be solved with a hand calculator.

    2018-01-01

    Fire whirls present a powerful intensification of combustion, long studied in the fire research community because of the dangers they present during large urban and wildland fires. However, their destructive power has hidden many features of their formation, growth, and propagation. Therefore, most of what is known about fire whirls comes from scale modeling experiments in the laboratory. Both the methods of formation, which are dominated by wind and geometry, and the inner structure of the whirl, including velocity and temperature fields, have been studied at this scale. Quasi-steady fire whirls directly over a fuel source form the bulk of current experimental knowledge, although many other cases exist in nature. The structure of fire whirls has yet to be reliably measured at large scales; however, scaling laws have been relatively successful in modeling the conditions for formation from small to large scales. This review surveys the state of knowledge concerning the fluid dynamics of fire whirls, including the conditions for their formation, their structure, and the mechanisms that control their unique state. We highlight recent discoveries and survey potential avenues for future research, including using the properties of fire whirls for efficient remediation and energy generation.

  10. Are Volunteer Satisfaction and Enjoyment Related to Cessation of Volunteering by Older Adults?

    Science.gov (United States)

    Okun, Morris; Infurna, Frank J; Hutchinson, Ianeta

    2016-05-01

    Previous research indicates that volunteer satisfaction and enjoyment do not exert direct effects on the cessation of volunteering by older adults. This study examined whether satisfaction with and enjoyment of volunteering indirectly affect volunteer cessation via hours volunteered. Our sample consisted of participants in the Americans' Changing Lives study (N = 380) who were 65 years old and older and who volunteered at Wave 1. Volunteer satisfaction, volunteer enjoyment, hours volunteered, and several covariates were assessed at Wave 1, and volunteer cessation was assessed 3 years later at Wave 2. Volunteer satisfaction and volunteer enjoyment were positively associated with hours volunteered, and more hours volunteered was associated with decreased likelihood of volunteer cessation. The indirect effects of volunteer satisfaction and volunteer enjoyment on volunteer cessation via hours volunteered were -.023 (p = .059) and -.036 (p = .015), respectively. The dynamics of volunteer cessation are important because a volunteer shortage is forecasted and because the benefits of volunteering may attenuate when volunteering stops. Future research should test the proposed causal sequence using longitudinal data with at least 3 waves. © The Author 2014.

In addition, information is produced on planning the supply chains, on raw material availability as well as on the applicability and competitiveness of Finnish technologies. In this work, business models are also developed with the aim of conceptualizing the whole supply system. The focus is on the highlands of EU, where the annual consumption of heat energy is close to the levels in Nordic Countries and which also often are outside the natural gas network. (orig.)

  12. The effect of coal-fired power-plant SO2 and NOx control technologies on aerosol nucleation in the source plumes

    Full Text Available Nucleation in coal-fired power-plant plumes can greatly contribute to particle number concentrations near source regions. The changing emissions rates of SO2 and NOx due to pollution-control technologies over recent decades may have had a significant effect on aerosol formation and growth in the plumes with ultimate implications for climate and human health. We use the System for Atmospheric Modeling (SAM large-eddy simulation model with the TwO-Moment Aerosol Sectional (TOMAS microphysics algorithm to model the nucleation in plumes of coal-fired plants. We test a range of cases with varying emissions to simulate the implementation of emissions-control technologies between 1997 and 2010. We start by simulating the W. A. Parish power plant (near Houston, TX during this time period, when NOx emissions were reduced by ~90% and SO2 emissions decreased by ~30%. Increases in plume OH (due to the reduced NOx produced enhanced SO2 oxidation and an order-of-magnitude increase in particle nucleation in the plume despite the reduction in SO2 emissions. These results suggest that NOx emissions could strongly regulate particle nucleation and growth in power-plant plumes. Next, we test a range of cases with varying emissions to simulate the implementation of SO2 and NOx emissions-control technologies. Particle formation generally increases with SO2 emission, while NOx shows two different regimes: increasing particle formation with increasing NOx under low-NOx emissions and decreasing particle formation with increasing NOx under high-NOx emissions. Next, we compare model results with airborne measurements made in the W. A. Parish power-plant plume in 2000 and 2006, confirming the importance of NOx emissions on new particle formation and highlighting the substantial effect of background aerosol loadings on this process (the more polluted background of the 2006 case caused more than an order-of-magnitude reduction in particle formation in the plume compared to

    In recent decades, nitrogen oxides (NOx) emissions from thermal power plant increased year by year in China. A large number of nitrogen oxides (NOx) emissions caused by the growing environmental problems have been widely attached importance to people. SCR denitrification technology has the advantages of cleanliness and high efficiency. At present, it has been the major technology to control NOx emission because of its high denitrification efficiency, reliable operation, no by-products and simple structure of the device. The denitrification efficiency can be stabilized at 70%. In this paper, three different denitrification methods are compared. The factors influencing the denitrification efficiency, the system arrangement and the key factors of the denitrification system are discussed in detail. And the numerical simulation of how to use this calculation software in the SCR reactor flue, baffle, reactor, spray ammonia grille and spray ammonia, mixer, etc. are reviewed, as well as the effect of system operation control on the deoxidation performance.

    The work summarized in this report is the first step towards a project that will re-train and create jobs for personnel in the coal industry and continue regional economic development to benefit regions impacted by previous downturns. The larger project is aimed at capturing ~300 tons/day (272 metric tonnes/day) CO2 at a 90% capture rate from existing coal- fired boilers at the Abbott Power Plant on the campus of University of Illinois (UI). It will employ the Linde-BASF novel amine-based advanced CO2 capture technology, which has already shown the potential to be cost-effective, energy efficient and compact at the 0.5-1.5 MWe pilot scales. The overall objective of the project is to design and install a scaled-up system of nominal 15 MWe size, integrate it with the Abbott Power Plant flue gas, steam and other utility systems, and demonstrate the viability of continuous operation under realistic conditions with high efficiency and capacity. The project will also begin to build a workforce that understands how to operate and maintain the capture plants by including students from regional community colleges and universities in the operation and evaluation of the capture system. This project will also lay the groundwork for follow-on projects that pilot utilization of the captured CO2 from coal-fired power plants. The net impact will be to demonstrate a replicable means to (1) use a standardized procedure to evaluate power plants for their ability to be retrofitted with a pilot capture unit; (2) design and construct reliable capture systems based on the Linde-BASF technology; (3) operate and maintain these systems; (4) implement training programs with local community colleges and universities to establish a workforce to operate and maintain the systems; and (5) prepare to evaluate at the large pilot scale level various methods to utilize the resulting captured CO2. Towards the larger project goal, the UI-led team, together

    Canuck Place Children's Hospice (CPCH) is regarded as one of the leading pediatric palliative care systems in the world. Since 1995, it has been providing hospice care free of charge to children and their families living with life-threatening conditions. The pediatric palliative hospice is a relatively new practice in health care, in comparison to the longstanding adult model. As a result, development and implementation of volunteer programs in pediatric hospices is not currently represented in literature. With over 300 volunteers at present, CPCH has built a successful program that can serve as a model in pediatric volunteer services. To present the unique volunteer roles and experience at CPCH, and share ways volunteers work to support the efforts of the clinical team. Strategies to address current challenges in the volunteer program are also addressed. Descriptive design. A current CPCH volunteer discusses the volunteer program. Interviews were conducted with the founding volunteer director of CPCH and current volunteers. The volunteer program at CPCH fully embraces the life of each child and family. Volunteer selection is the groundwork for ensuring a cohesive work force, while training equips volunteers with the knowledge to carry out their role with confidence. Areas of improvement that have been recognized include offering effective feedback to volunteers and delivering adequate level of training for non-direct care roles. The talents of volunteers at CPCH are diverse, and CPCH aims to recognize and thank volunteers for their continuous contributions.

    Full Text Available The combustion of coal wastes resulting from mining is of particular environmental concern, and the importance of proper management involving real-time assessment of their status and identification of probable evolution scenarios is recognized. Continuous monitoring of the combustion temperature and emission levels of certain gases allows for the possibility of planning corrective actions to minimize their negative impact on the surroundings. Optical fiber technology is well suited to this purpose and here we describe the main attributes and results obtained from a fiber optic sensing system projected to gather data on distributed temperature and gas emissions in these harsh environments.

    According to experience and probabilistic risk assessments, fires present a significant hazard in a nuclear power plant. Fires may be initial events for accidents or affect safety systems planned to prevent accidents and to mitigate their consequences. The project consists of theoretical work, experiments and simulations aiming to increase the fire safety at nuclear power plants. The project has four target areas: (1) to produce validated models for numerical simulation programmes, (2) to produce new information on the behavior of equipment in case of fire, (3) to study applicability of new active fire protecting systems in nuclear power plants, and (4) to obtain quantitative knowledge of ignitions induced by important electric devices in nuclear power plants. These topics have been solved mainly experimentally, but modelling at different level is used to interpret experimental data, and to allow easy generalisation and engineering use of the obtained data. Numerical fire simulation has concentrated in comparison of CFD modelling of room fires, and fire spreading on cables on experimental data. So far the success has been good to fair. A simple analytical and numerical model has been developed for fire effluents spreading beyond the room of origin in mechanically strongly ventilated compartments. For behaviour of equipment in fire several full scale and scaled down calorimetric experiments were carried out on electronic cabinets, as well as on horizontal and vertical cable trays. These were carried out to supply material for CFD numerical simulation code validation. Several analytical models were developed and validated against obtained experimental results to allow quick calculations for PSA estimates as well as inter- and extrapolations to slightly different objects. Response times of different commercial fire detectors were determined for different types of smoke, especially emanating from smoldering and flaming cables to facilitate selection of proper detector

Current radiological emergency exercise is basically conducting in the field. The field exercise essentially requires participation of mass population. Due to lack of time, cost, communication and participation, the field exercise necessarily causes several limitations in an aspect of effectiveness. The public participants often misunderstood the situation as real though it is just an exercise so several conflicts are occurring. Furthermore, the exercise program is too ideal to reflect the real accident situation. In this point of view, application of virtual reality (VR) technology is highlighted with its many advantages. VR technology is expected to resolve those existing problems. Our research team is currently developing VR based radiological emergency exercise system. In this paper, the advantages and actual application of VR based training were introduced. With those advantages and improvement of existing disadvantages, our VR based radiological emergency exercise system will be developed. Not only physical interactive features, but also interactive fail-considered real-like scenarios will be adopted in the system. The ultimate goal of the system is safe and perfect evacuation of residents in case of radioactive accident.

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available The nineteenth century theatre was fire-prone, to say the least. Across the century there were more than 1,100 major conflagrations in the world’s theatres, and countless smaller fires. In Great Britain almost every theatre seems to have burned down at some point. And yet, despite, or perhaps in part because of, this appalling record, fires were a staple feature of stage spectacle. Some plays placed them at the very centre of the entertainment, and as the century went on stage fires became more and more elaborate. Actual or simulated conflagrations were conjured up using a diverse array of technologies, some of them very simple, some depending on the most recent scientific discoveries. Here, I give a short tour of these technologies and their use in the plays of the period, and suggest some of the pleasures that they offered. While onstage flames could draw people in, offering an experience of immersive suspense, for instance, they also interrupted the dramatic flow, reminding audiences that they were seeing a performance, getting something for their money. To this extent, we are reminded that nineteenth-century drama provided something of a mixed and spectacular ‘theatre of attractions’, closer at times to the circus than to the novel.

    Boezeman, Edwin J; Ellemers, Naomi

    2008-09-01

    In 3 experiments the authors examined how specific characteristics of charitable volunteer organizations contribute to the recruitment of new volunteers. In line with predictions, Study 1 revealed that providing non-volunteers with information about organizational support induced anticipated feelings of respect, which subsequently enhanced their attraction to the volunteer organization. However, information about the current success of the volunteer organization did not affect anticipated pride (as among those who seek paid employment) and in fact caused potential volunteers to perceive the organization as being in less need for additional volunteers. Study 2 further showed that information about support from the volunteer organization is a more relevant source of anticipated respect and organizational attraction than support from co-volunteers. Study 3 finally showed that information about task and emotional support for volunteers contributes to anticipated respect and organizational attractiveness and that this increases the actual willingness of non-volunteers to participate in the volunteer organization. Interventions aimed at attracting volunteers and avenues for further research are discussed.

    This study investigates the interplay among religiosity, spirituality, value-expressive volunteer motivation, and volunteering. We examined religiosity and spirituality as predictors of value-expressive volunteer motivation and volunteering and whether religiosity moderated the relations between (a) spirituality and value-expressive volunteer motivation and (b) value-expressive volunteer motivation and volunteering. After applying multiple imputation procedures to data from the Wisconsin Longitudinal Study among participants 64-67 years old who survived beyond 2004 (N = 8,148), we carried out regression analyses to predict value-expressive volunteer motivation and volunteering from religiosity and spirituality controlling for demographic variables, physical, emotional, and cognitive health, health risk behaviors, and personality traits. Both religiosity and spirituality were significant (p volunteer motivation. Value-expressive volunteer motivation and religiosity were significant (p volunteering. Religiosity amplified the relation between value-expressive volunteer motivation and volunteering (p volunteer motivation (p > .45). Religiosity may provide the way, and value-expressive volunteer motivation the will, to volunteer. The implications of our findings for the forecasted shortage of older volunteers are discussed. © The Author 2014.

    2015-12-01

    Full Text Available The aim of this paper is to present engaged anthropology and its methodological tools with a specific perspective of the research field and the position of the researcher with regard to research subjects. The study focuses on corporate volunteering as one of the forms of collaboration between the non-profit and the private sectors seeking solutions to social problems and community development. Volunteering projects contribute to the interlinking of the knowledge, skills, experience and resources of corporate employees and the representatives of the non-profit or the public sector. It is a part of the philanthropic strategy of companies which are willing to present themselves as entities responsible towards the environment in which they run their business, and towards their employees, partners and customers. Engaged anthropology can bring, through its methodological tools, a new perspective of corporate volunteering. Community-based participatory research on the process of knowledge creation includes all partners on an equal basis and identifies their unique contribution to problem solution and community development.

    2006-01-01

    While diverse studies carried out in nursing and medical personnel have demonstrated that health workers can be subject to burnout, little effort has been focused on investigating burnout in volunteer hospital workers. The aim of the present study was to verify if burnout exists with volunteer auxiliary personnel and investigate what organizational conditions may favour it. The study was carried out on 80 volunteer workers of the Red Cross of Mortara (PV), subdivided into two categories: those performing emergency interventions and those performing routine services. For the evaluation of burnout, the Italian version of the Maslach Burnout Inventory was used, together with a qualitative type of methodology. A 5-factor multivariate analysis (sex x shift x team x seniority x role), having as dependent variables the three scales of the MBI, showed that the highest values of depersonalization and fulfillment are found in the emergency team, and that subjects with least seniority are those who are least satisfied or fulfilled. The category of team-leader resulted as that with the highest values of emotional burnout, while sex- and shift-based differences were restricted to routine service workers. Despite these differences, findings showed that subjects are minimally affected by problems linked to burnout, although some relational and organizational difficulties emerged with the medical staff that underlie a certain degree of professional dissatisfaction.

    Directory of Open Access Journals (Sweden)

    I.H. EL-Gamily

    2010-06-01

    Full Text Available Wireless GIS services have been evolving from scientific and technological perspectives through the last two decades. These services include both the location-based services (LBS and the mobile field-based GIS. Whereas the former provides the user with the capability to access and query the already established enterprise geo-database, the latter enables the end user not only to access and query but also to update the geo-database by a near real-time spatial and non-spatial data. However, to establish a mobile field-based GIS facility, a concise system architecture should be designed. This architecture includes client-side components, wireless communication facility, and server components. The integration and automation of these components can provide the capability to collect, update, validate, and query the enterprise geo-database remotely in a near real-time mode. One of the potential fields of applications for the mobile field-based GIS is the crisis management process. A prescribed system has been previously defined as emergency response cycle for managing both the natural and the man-made crises. Three phases of the emergency response cycle are outlined which are the response and rescue phase, the recovery and reconstruction phase, and mitigation and preparedness phase. In each phase, various tasks are undertaken based on the type of the event. Selective tasks of the response and the rescue phase of the fire event occurred in the Sheraton Exchange Center have been chosen to check the validity of using the mobile field-based GIS for enhancing the performance of these tasks. These tasks are path selection and quick damage estimates.

    2017-02-01

    The aim of this article is to describe the potential with respect to volunteer work among 55 to 70-year-old persons along with a two-dimensional typology (actual volunteer work and intention of volunteering or expanding actual volunteer work) and to identify the influencing factors. Based on the dataset from the transitions and old age potential (TOP) study, a total of 4421 men and women born between 1942 and 1958 were included. A multinomial regression model showed the predictors for group affiliation along with an engagement-related typology (internal, utilized and external volunteer potential as well as definite non-volunteers). More than a half of the persons in the study sample could be classified as internal or external volunteer potential. Volunteers and potential volunteers revealed more similarities regarding resources and social factors than potential volunteers and definite non-volunteers. Potential volunteers were more active in other informal fields of activity (e.g. nursing or child care) than definite non-volunteers. With respect to volunteer work, definite non-volunteers showed various social disadvantages (in particular with respect to education and health) compared to (potential) volunteers. Other informal activities did not seem to be in major conflict with volunteer activities, e.g. nursing or child care, as long as they were carried out with moderate or low intensity.

  20. Volunteering as a predictor of all-cause mortality: what aspects of volunteering really matter?

    Science.gov (United States)

    Ayalon, Liat

    2008-10-01

    This study evaluates the predictive effects of different aspects of volunteering (e.g. volunteering status, number of hours, number of years, and type of volunteering activity) on all-cause mortality. A seven-year follow-up dataset of a nationally representative sample of Israelis, 60 years and older was used. As expected, volunteering was associated with a reduced mortality risk even after adjusting for age, gender, education, baseline mental health and physical health, activity level, and social engagement. Those who volunteered for 10 to 14 years had a reduced mortality risk relative to non-volunteers. In addition, those who volunteered privately, not as part of an official organization, also had a reduced mortality risk compared to non-volunteers. The number of hours of volunteering was not a significant predictor of all-cause mortality in the fully adjusted model. In additional sensitivity analyses limited to those who volunteered, none of the various aspects of volunteering was associated with a reduced mortality risk. Results suggest that not all aspects of volunteering have the same predictive value and that the protective effects of length of volunteering time and type of volunteering are particularly important. However, whether or not volunteering is the most consistent predictor of mortality and whether once a person volunteers the various aspects of volunteering are no longer associated with mortality risk.

    Computing for the LHC, and for HEP more generally, is traditionally viewed as requiring specialized infrastructure and software environments, and therefore not compatible with the recent trend in v olunteer computing , where volunteers supply free processing time on ordinary PCs and laptops via standard Internet connections. In this paper, we demonstrate that with the use of virtual machine technology, at least some standard LHC computing tasks can be tackled with volunteer computing resources. Specifically, by presenting volunteer computing resources to HEP scientists as a v olunteer cloud , essentially identical to a Grid or dedicated cluster from a job submission perspective, LHC simulations can be processed effectively. This article outlines both the technical steps required for such a solution and the implications for LHC computing as well as for LHC public outreach and for participation by scientists from developing regions in LHC research.

    Friedman, Robert

    1987-01-01

    This paper reviews the state-of-the-art in fire control techniques and identifies important issues for continuing research, technology, and standards. For the future permanent orbiting facility, the space station, fire prevention and control calls for not only more stringent fire safety due to the long-term and complex missions, but also for simplified and flexible safety rules to accommodate the variety of users. Future research must address a better understanding of the microgravity space environment as it influences fire propagation and extinction and the application of the technology of fire detection, extinguishment, and material assessment. Spacecraft fire safety should also consider the adaptation of methods and concepts derived from aircraft and undersea experience.

  13. Volunteering in later life: research frontiers.

    Science.gov (United States)

    Morrow-Howell, Nancy

    2010-07-01

    This review summarizes the current knowledge about volunteering in later life and suggests 5 research questions at the forefront of knowledge development. Rates of volunteering do not decline significantly until the middle of the 7th decade, and older volunteers commit more hours than younger volunteers. Older adults with more human and social capital tend to volunteer, and there is good evidence of a reciprocal relationship between volunteering and well-being. Program and policy developments in the field are outstripping production of knowledge to support evidence-based practices. Research on the dynamics of volunteering over the life course as well as the patterns of activities that co-occur with volunteering is needed to guide program development. Research methods and findings from transdisciplinary work on the mechanisms through which psychosocial conditions affect health must be extended to the study of the effects of volunteering on older adults. Finally, we need to engage in more applied social science aimed at improving volunteer management, especially recruitment and retention of older volunteers.

  14. The stresses of hospice volunteer work.

    Science.gov (United States)

    Brown, Mary V

    2011-05-01

    The purpose of this phenomenological study was to explore the interpretation of stress, the appraisal of the stressors, as well as the top stressors experienced by hospice volunteers. Individual semistructured interviews were conducted with 15 hospice volunteers. The interviews were digitally recorded, transcribed, and analyzed, using qualitative research methods. Although the results indicated that the hospice volunteers did not perceive their work as stressful, 2 main themes regarding challenging experiences did emerge. Hospice-related issues and personal issues were of concern to the volunteers. In addition, the timing of the stressors revealed that the most stress was felt at the beginning of their volunteer services, which has implications for hospice volunteer coordinators as they support their volunteers in the field.

    Skorek-Osikowska, Anna; Bartela, Lukasz; Kotowicz, Janusz; Job, Marcin

    2013-01-01

    Highlights: • Mathematical models of an integrated oxy-combustion power plant. • Thermodynamic analysis of the modeled different cases of the plant. • Analysis of the methods of increasing the net efficiency of the plant. • Economic comparative analysis of the air-type and oxy-type plants. - Abstract: In the face of existing international provisions limiting the emissions of greenhouse gases, primarily carbon dioxide, it is necessary to introduce solutions that will allow the production of electricity from coal with high efficiency and low emissions. Oxy-combustion systems integrated with carbon capture and storage (CCS) installations may prove to be such a solution. This paper presents the main results from a thermodynamic analysis of a supercritical unit operating in oxy-combustion technology, fueled with pulverized coal with a power output of 460 MW. The parameters of the live steam in the analyzed system are 600 °C/30 MPa. To perform the numerical analyses, models of the individual components were built, including an oxygen production installation (ASU), a boiler, a steam cycle and a flue gas conditioning system (CPU). The models were built in the commercial programs GateCycle and Aspen and then integrated into the Excel environment. In this paper, different structures for an integrated oxy-type system were analyzed and compared. The auxiliary power rates were determined for individual technological installations of the oxy-combustion power plant. The highest value of this indicator, in the range between 15.65% and 19.10% was calculated for the cryogenic ASU. The total value of this index for the whole installation reaches as high as 35% for the base case. The use of waste heat from the interstage cooling of compressors in the air separation installation and flue gas conditioning system was considered as the methods of counteracting the efficiency decrease resulting from the introduction of ASU and CPU. The proposed configurations and optimization

    Trouvé, Arnaud; Wang, Yi

    2010-12-01

    This paper is aimed at illustrating the capabilities of contemporary large eddy simulation (LES) solvers for compartment fire applications. Compartment fires refer to fires occurring indoors and feature a variety of complex phenomena associated with smoke accumulation and restricted air ventilation. The article provides a brief presentation of the main features of compartment fire dynamics followed by a review of the modelling challenges found in a LES treatment of these dominant features. The discussion shows that in addition to a suitable model for the turbulent flow dynamics, simulations of compartment fires require a collection of physical sub-models in order to describe a large range of multi-physics phenomena, including pyrolysis processes, buoyancy-driven flow, combustion, soot formation and thermal radiation. Some examples of LES simulations of compartment fires are also presented, using two different solvers that represent the current state-of-the-art of compartment fire modelling: FDS developed by the National Institute of Standards and Technology, USA, and FireFOAM developed by FM Global, USA. Both solvers are available as free open-source software and are representative of ongoing efforts within the fire research and engineering community to self-organise and to promote the general area of LES-based fire modelling.

  11. Post-Event Volunteering Legacy: Did the London 2012 Games Induce a Sustainable Volunteer Engagement?

    Directory of Open Access Journals (Sweden)

    Niki Koutrou

    2016-11-01

    Full Text Available The hosting of the London 2012 Olympic Games was seen as an opportunity to harness the enthusiasm of the 70,000 volunteers involved and to provide a post-event volunteer legacy. A total of 77 individuals who had acted as volunteers in London 2012 were contacted approximately four years after the Games and agreed to complete a web-based open-ended survey. The participants were asked to indicate their level of current volunteering engagement and whether volunteering at the Games had an impact on their current volunteering levels. The study found that the London Olympics were the first volunteer experience for most of the volunteers who completed the survey, with the main motivation to volunteer being anything related to the Olympic Games. Just over half of the respondents are currently volunteering. Lack of time is shown to be the main barrier towards further volunteering commitment. Only half of respondents had been contacted by a volunteering scheme after London 2012. The implications of the findings for a potential volunteering legacy are then explored.

  12. Environmental volunteer well-being: Managers' perception and actual well-being of volunteers.

    Science.gov (United States)

    Kragh, Gitte; Stafford, Rick; Curtin, Susanna; Diaz, Anita

    2016-01-01

    Background : Environmental volunteering can increase well-being, but environmental volunteer well-being has rarely been compared to participant well-being associated with other types of volunteering or nature-based activities. This paper aims to use a multidimensional approach to well-being to explore the immediately experienced and later remembered well-being of environmental volunteers and to compare this to the increased well-being of participants in other types of nature-based activities and volunteering. Furthermore, it aims to compare volunteer managers' perceptions of their volunteers' well-being with the self-reported well-being of the volunteers. Methods : Onsite surveys were conducted of practical conservation and biodiversity monitoring volunteers, as well as their control groups (walkers and fieldwork students, respectively), to measure general well-being before their nature-based activity and activity-related well-being immediately after their activity. Online surveys of current, former and potential volunteers and volunteer managers measured remembered volunteering-related well-being and managers' perceptions of their volunteers' well-being. Data were analysed based on Seligman's multidimensional PERMA ('positive emotion', 'engagement', 'positive relationship', 'meaning', 'achievement') model of well-being. Factor analysis recovered three of the five PERMA elements, 'engagement', 'relationship' and 'meaning', as well as 'negative emotion' and 'health' as factors. Results : Environmental volunteering significantly improved positive elements and significantly decreased negative elements of participants' immediate well-being, and it did so more than walking or student fieldwork. Even remembering their volunteering up to six months later, volunteers rated their volunteering-related well-being higher than volunteers rated their well-being generally in life. However, volunteering was not found to have an effect on overall mean well-being generally in life

  14. Demonstration of Selective Catalytic Reduction (SCR) technology for the control of nitrogen oxide (NO{sub x}) emissions from high-sulfur coal-fired boilers. Technical progress report, first and second quarters 1994

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    1995-11-01

    The objective of this project is to demonstrate and evaluate commercially available Selective Catalytic Reduction (SCR) catalysts from U.S., Japanese and European catalyst suppliers on a high-sulfur U.S. coal-fired boiler. SCR is a post-combustion nitrogen oxide (NO{sub x}) control technology that involve injecting ammonia into the flue gas generated from coal combustion in a boiler. The flue gas containing ammonia is then passed through a reactor that contains a specialized catalyst. In the presence of the catalyst, the ammonia reacts with NO{sub x} to form nitrogen and water vapor. Although SCR is widely practiced in Japan and Europe on gas-, oil-, and low-sulfur coal-fired boilers, there are several technical uncertainties associated with applying SCR to U.S. coals. These uncertainties include: (1) potential catalyst deactivation due to poisoning by trace metal species present in U.S. coals that are not present in other fuels; (2) performance of the technology and effects on the balance-of-plant equipment in the presence of high amounts of SO{sub 2} and SO{sub 3}; and (3) performance of a wide variety of SCR catalyst compositions, geometries and methods of manufacture under typical high-sulfur coal-fired utility operating conditions. These uncertainties are being explored by operating a series of small-scale SCR reactors and simultaneously exposing different SCR catalysts to flue gas derived from the combustion of high sulfur U.S. coal. The project is being conducted in the following three phases: permitting, environmental monitoring plan and preliminary engineering; detailed design engineering and construction; and operation, testing, disposition and final report. The project was in the operation and testing phase during this reporting period. Accomplishments for this period are described.

    Directory of Open Access Journals (Sweden)

    Karen Smith

    2010-01-01

    Full Text Available Programmes targeting student volunteering and service learning are part of encouraging civic behaviour amongst young people. This article reports on a large scale international survey comparing volunteering amongst tertiary students at universities in Australia, Canada, New Zealand, the United Kingdom, and the United States of America. The data revealed high rates of student volunteering and the popularity of occasional or episodic volunteering. There were strong commonalities in student volunteering behaviour, motivations and benefits across the five Western predominately English-speaking countries. Altruism and self-orientated career motivations and benefits were most important to students; however volunteering and non-volunteering students differed in the relative value they attached to volunteering for CV-enhancement and social factors.

  17. Recording and Evaluating the Role of Volunteers Regarding Natural Hazards Prevention and Disaster Management in Greece

    Papanikolaou, Ioannis; Papanikolaou, Dimitrios; Diakakis, Michalis; Deligiannakis, Georgios

    2013-04-01

    The role of volunteers in disaster management is of decisive importance, particularly for major catastrophes. In Northern Europe, volunteers are the main group that responds even in regular low impact incidents. On the other hand, in Southern Europe, state professionals hold the primary role. This is partly cultural, but it is also defined by the different types of hazards involved. For example, Southern Europe suffers from earthquakes and wildfires that can cause severe and widespread damage. This implies that there is a need for highly trained and skilled personnel, not only for efficiency purposes, but also in order to avoid casualties among the operating staff. However, the need of volunteers' involvement is well recognised both for prevention measures (mainly regarding forest fires) and for disaster management purposes particularly during major catastrophes whereas the professional personnel are outsourced. Moreover, the economic crisis stretches the public sector, decreasing the capability and resources of the state mechanism. The latter increases the need for the volunteers' active participation, which is also regarded as cost effective. Greece has a short tradition regarding volunteers and their official involvement with natural hazards. This is also due to the fact that civil protection has a short history in Greece, since it was established in 1995, whereas its legal framework was only shaped in 2002. The act 3013/2002 introduces officially the role of volunteers within the legal framework. In particular, the act N3013/2002 offers a detailed description of the role of voluntary organizations within the civil protection system, the interagency cooperation, and the financial instruments through which the various bodies secure their funding along with the establishment of an inventory from the General Secretariat of Civil Protection. However, several provisions described in the 2002 Act have not been applied yet. For instance voluntary organizations are not

    A variety of organizations redistribute surplus food to low-income populations through food rescue nutrition. Why volunteers participate in these charitable organizations is unclear. The aim of this study is to document the participation and motivations of volunteers who are involved specifically in food rescue nutrition. A cross-sectional study was conducted in two phases. In phase 1, a new instrument, Motivations to Volunteer Scale, was developed and validated in 40 participants (aged ≥18 years). In phase 2, the new scale and a demographics questionnaire were administered to 300 participants who were volunteering in food pantries and churches. The pilot study showed that Motivations to Volunteer Scale exhibited an internal consistency of Cronbach's α of 0.73 (P  0.05). The scale was validated also by comparison to the Volunteer Function Inventory (r = 0.86, P Motivations to Volunteer Scale were requirement, career improvement, social life, and altruism. The mean motivation score of the 300 volunteers was 9.15 ± 0.17. Greater motivations were observed among participants who were aged >45 years, women, Hispanics, college/university graduates, physically inactive, non-smokers, and had an income ≥ $48,000. The Motivations to Volunteer Scale is a valid tool to assess why individuals volunteer in food rescue nutrition. The extent of motivations of participants was relatively high, and the primary reason for volunteering was altruism. Health professionals should be encouraged to participate in food redistribution.

  19. Opportunities and improvisations: a pediatric surgeon's suggestions for successful short-term surgical volunteer work in resource-poor areas.

    Science.gov (United States)

    Meier, Donald

    2010-05-01

    There is a paucity of trained pediatric surgeons in resource-poor areas, and many children never receive care for debilitating problems that could readily be managed by surgeons with proper training, supplies, and instrumentation. This article, written from the perspective of a surgeon who has been both the recipient of and the provider of volunteer surgical services, is intended to encourage surgeons in technologically advanced locations to volunteer in underserved areas and to assist them in the implementation of such endeavors. Concepts are presented with an emphasis on pediatric surgery, but most are relevant for volunteers in all surgical specialties. Volunteer paradigms include, but are not limited to, the "surgical brigade" model, where a large group of health care professionals take all needed equipment and supplies for the duration of their stint, and the "minimalist" model, where a single volunteer works with local personnel using locally available equipment. For a successful volunteer endeavor the host needs to have a perceived need for the volunteer's services, and the volunteer must be flexible in adapting to meet overwhelming needs with limited resources. It is suggested that appropriate technology, such as the inexpensive anal stimulator presented herein, should be employed whenever possible. With proper planning, realistic expectations, and a cooperative and helpful attitude, volunteer trips can be rewarding experiences for both volunteers and host physicians and lead to lasting relationships that improve children's lives globally.

  16. Serbian Volunteers And Russian Revolution Of 1917

    Directory of Open Access Journals (Sweden)

    Ia. V. Vishniakov

    2017-01-01

    Full Text Available Using original documents from the Russian State Military Historical Archive, many of which are introduced for the first time, the author reveals details of creation and activities of the Serbian Volunteer Corps formed from captured soldiers and officers of the Austro-Hungarian army inOdessain the Summer 1916. The same autumn it received a baptism of fire in Dobruja fighting in the separate corps of the Russian army under the command of General Zayonchkovsky. The research interest in studying the activities of “national” and "international" military units within the Russian army is connected with the question of expediency and effectiveness of using such forces against those for whom they have not so long ago shed blood. The author, contrary to the popular opinion of Serbian historians, shows that the call to join the First Serbian division did not arouse mass enthusiasm among the prisoners of war both Serbs and representatives of other Yugoslav nations because of well-founded fears for their close relatives living in the Dual Monarchy and a fairly comfortable stay in the Russian captivity. At the same time, the author emphasizes that this military unit, commanded by officers of the Serbian regular army, was considered by the political leadership ofSerbiaas the basis of the future armed forces of the new state ofYugoslavia. The article shows that the events of the Russian Revolution of 1917 influenced the future fate of this military formation. Many of its soldiers later found themselves on different sides of the front in the Russian civil war. A special attention is payed to the interethnic conflict erupted in the corps between the Serbs on the one side and the Croats and Slovenes on the other. The author introduces a significant body of primary documents showing the nuances of relations in the corps between representatives of various Yugoslav nations. The article emphasizes that the relationship of the Serbs, Croats and Slovenes within the

  18. Environmental volunteer well-being: Managers’ perception and actual well-being of volunteers

    Kragh, Gitte; Stafford, Rick; Curtin, Susanna; Diaz, Anita

    2016-01-01

    Background: Environmental volunteering can increase well-being, but environmental volunteer well-being has rarely been compared to participant well-being associated with other types of volunteering or nature-based activities. This paper aims to use a multidimensional approach to well-being to explore the immediately experienced and later remembered well-being of environmental volunteers and to compare this to the increased well-being of participants in other types of nature-based activities and volunteering. Furthermore, it aims to compare volunteer managers’ perceptions of their volunteers’ well-being with the self-reported well-being of the volunteers. Methods: Onsite surveys were conducted of practical conservation and biodiversity monitoring volunteers, as well as their control groups (walkers and fieldwork students, respectively), to measure general well-being before their nature-based activity and activity-related well-being immediately after their activity. Online surveys of current, former and potential volunteers and volunteer managers measured remembered volunteering-related well-being and managers’ perceptions of their volunteers’ well-being. Data were analysed based on Seligman’s multidimensional PERMA (‘positive emotion’, ‘engagement’, ‘positive relationship’, ‘meaning’, ‘achievement’) model of well-being. Factor analysis recovered three of the five PERMA elements, ‘engagement’, ‘relationship’ and ‘meaning’, as well as ‘negative emotion’ and ‘health’ as factors. Results: Environmental volunteering significantly improved positive elements and significantly decreased negative elements of participants’ immediate well-being, and it did so more than walking or student fieldwork. Even remembering their volunteering up to six months later, volunteers rated their volunteering-related well-being higher than volunteers rated their well-being generally in life. However, volunteering was not found to have an

    Full Text Available The aim of this study was to test the possibility of predicting volunteer motives based on five-factor model of personality in a sample of 159 volunteers from Zagreb, Osijek and Split. Data was collected using IPIP-300 personality questionnaire and Volunteer Functions Inventory. Results indicate that Croatian volunteers are agreeable, conscientious, altruistic, dutiful, and moral persons with artistic interests. Their most salient motives for volunteering are understanding and values. Hierarchical regression analysis confirmed that the five-factor model personality traits independently predict 17% of protective motive variance, 12% of values motive, 18% of career motive, 10% of understanding motive, and 12% of enhancement motive. Social motive was not explained by personality traits.

  20. Semantic Similarity Assessment of Volunteered Geographic Information

    Directory of Open Access Journals (Sweden)

    Maythm M. Albakri

    2017-01-01

    Full Text Available The recent development in communication technologies between individuals allows for the establishment of more informal collaborative map data projects which are called volunteered geographic information (VGI. These projects, such as OpenStreetMap (OSM project, seek to create free alternative maps which let users add or input new materials to the data of others. The information of different VGI data sources is often not compliant to any standard and each organization is producing a dataset at various level of richness. In this research the assessment of semantic data quality provided by web sources, e.g. OSM will depend on a comparison with the information from standard sources. This will include the validity of semantic accuracy as one of the most important parameter of spatial data quality parameters. Semantic similarity testing covered feature classification, in effect comparing possible categories (legend classes and actual attributes attached to features. This will be achieved by developing a tool, using Matlab programming language, for analysing and examining OSM semantic accuracy. To identify the strength of semantic accuracy assessment strategy, there are many factors should be considered. For instance, the confusion matrix of feature classifications can be assessed, and different statistical tests should be passed. The results revealed good semantic accuracy of OSM datasets.

    2012-12-01

    The Council for Scientific and Industrial Research (CSIR) lead by the Meraka Institute and supported by the South African National Space Agency (SANSA) developed the Advanced Fire Information System (AFIS) to provide near real time fire information to a variety of operational and science fire users including disaster managers, fire fighters, farmers and forest managers located across Southern and Eastern Africa. The AFIS combines satellite data with ground based observations and statistics and distributes the information via mobile phone technology. The system was launched in 2004, and Eskom (South Africa' and Africa's largest power utility) quickly became the biggest user and today more than 300 Eskom line managers and support staff receive cell phone and email fire alert messages whenever a wildfire is within 2km of any of the 28 000km of Eskom electricity transmission lines. The AFIS uses Earth observation satellites from NASA and Europe to detect possible actively burning fires and their fire radiative power (FRP). The polar orbiting MODIS Terra and Aqua satellites provide data at around 10am, 15pm, 22am and 3am daily, while the European Geostationary MSG satellite provides 15 minute updates at lower spatial resolution. The AFIS processing system ingests the raw satellite data and within minutes of the satellite overpass generates fire location and FRP based fire intensity information. The AFIS and new functionality are presented including an incident report and permiting system that can be used to differentiate between prescribed burns and uncontrolled wild fires, and the provision of other information including 5-day fire danger forecasts, vegetation curing information and historical burned area maps. A new AFIS mobile application for IOS and Android devices as well as a fire reporting tool are showcased that enable both the dissemination and alerting of fire information and enable user upload of geo tagged photographs and on the fly creation of fire reports

    2016-06-01

    Another prerequisite of volunteerism was the surge of Advantages Revolution in 2013-2014, and after it – the anti-terrorist operation in eastern Ukraine. In 2015 the aid organization in terms of ATO and internally displaced persons has increased directions volunteering. Important indicators of volunteering were high levels of involvement of Ukrainian philanthropy and consequently public confidence in voluntary organizations, qualitative growth of volunteerism, the founders of which were gradually included among the managerial elite Ukraine. At the same time, there are number of problems that discredit the work of volunteers and the idea of volunteering in general, for example, fraud volunteers and fake organizations. Moreover, the increased activity of the volunteer movement was caused by the internal crisis that led to the imbalance of public administration, lack of high-quality management decisions, lack of resource capabilities. Also it was caused by external factors, such as the need to participate in the organization of international events and conduct military operations against separatist groups in eastern Ukraine. So, volunteer activity gradually becomes an effective mechanism of self-organization of citizens.

  6. Motivation to volunteer among senior center participants.

    2018-04-01

    Senior centers in the United States play a vital role in the aging continuum of care as the focal points of a community-based system of services targeting independent older adults to promote their social integration and civically engagement. Although several studies have evaluated the diversity of senior center programs, demographic characteristics of participants, and benefits of participation, very few have explored motivations to volunteer among participants. Many senior centers rely on a cadre of participants who volunteer there to assist with programs and meal services. However, a systematic examination of volunteering interests and the rationale for volunteering among senior center participants has been missing from the literature. This mixed-methods study, conducted at a large suburban senior center, explores the interests and motivations of volunteerism among the participants. The study found that there was limited interest in volunteering among senior center participants. Those who were motivated to volunteer wanted to do so in order to stay connected with their community. There was strong interest in volunteering for single events or projects rather than a long-term commitment. Implications for senior centers are discussed.

    The preliminary assessment of many radiopharmaceuticals is often carried out with the help of normal volunteers. These volunteers are drawn from the general public, are fully informed of the procedure to be performed and its attendant risks, and in many cases are compensated financially for their trouble. The cooperation of such people is of vital importance to the full understanding of the normal kinetics and metabolism of many new radiopharmaceuticals. The restrictions on the choice of normal volunteers, and the radiation dose limits which must be observed are not explicitly defined in any of the current guidelines, and in this paper we propose a rationale, based upon available information, which sets acceptable limits for volunteers, and provides a framework within which scientists and physicians can work

    1992-01-01

    Volunteers are integral members of the hospice interdisciplinary team. They are distinguished from other members of the team only by role, not by expectation. The distinction is not between "volunteer" and "professional," because every team member is to be professional in the best sense of that word. If a distinction is to be made, it is that some hospice staff members are salaried while others donate their services. Volunteer staff members are expected to be as responsible and accountable as every other member of the team. ALL staff members must realize the importance of taking care of personal needs in order to be able to care for others. Even though the following article deals primarily with the volunteer hospice staff member, the points outlined can just as easily be applied to the salaried staff member.

    2013-08-01

    In all, 119 hospice palliative care volunteers from 3 community-based hospice programs completed the Volunteer Retention Questionnaire (VRQ), a 33-item survey designed for this study. The VRQ asks volunteers to rate the importance of each item to their decision to continue volunteering. The items that received the highest mean importance ratings included enjoying the work they do, feeling adequately prepared/trained to perform their role, and learning from their patients' experiences/listening to their patients' life stories. Being recognized (eg, pins for years of service or being profiled in the hospice newsletter), receiving phone calls/cards from their volunteer coordinator on special occasions, and being reimbursed for out-of-pocket expenses were among the items that received the lowest mean importance ratings. Suggestions for improving volunteer retention are provided.

  4. Probabilistic Flood Mapping using Volunteered Geographical Information

    Rivera, S. J.; Girons Lopez, M.; Seibert, J.; Minsker, B. S.

    2016-12-01

    Flood extent maps are widely used by decision makers and first responders to provide critical information that prevents economic impacts and the loss of human lives. These maps are usually obtained from sensory data and/or hydrologic models, which often have limited coverage in space and time. Recent developments in social media and communication technology have created a wealth of near-real-time, user-generated content during flood events in many urban areas, such as flooded locations, pictures of flooding extent and height, etc. These data could improve decision-making and response operations as events unfold. However, the integration of these data sources has been limited due to the need for methods that can extract and translate the data into useful information for decision-making. This study presents an approach that uses volunteer geographic information (VGI) and non-traditional data sources (i.e., Twitter, Flicker, YouTube, and 911 and 311 calls) to generate/update the flood extent maps in areas where no models and/or gauge data are operational. The approach combines Web-crawling and computer vision techniques to gather information about the location, extent, and water height of the flood from unstructured textual data, images, and videos. These estimates are then used to provide an updated flood extent map for areas surrounding the geo-coordinate of the VGI through the application of a Hydro Growing Region Algorithm (HGRA). HGRA combines hydrologic and image segmentation concepts to estimate a probabilistic flooding extent along the corresponding creeks. Results obtained for a case study in Austin, TX (i.e., 2015 Memorial Day flood) were comparable to those obtained by a calibrated hydrologic model and had good spatial correlation with flooding extents estimated by the Federal Emergency Management Agency (FEMA).

Seventeen (65% of the 26 LHIs were relevant to Peace Corps Volunteers. Of these, Volunteers' health measures met or were more favorable than the goals of 13 (76% of the LHIs. There were no data available for 4 (24% of the LHIs. The entire Volunteer population has full access to primary care, oral health, and reproductive health services. No suicides or homicides were reported among Volunteers during the analyzed time period. Utilizing the LHIs, we have identified high-priority public health issues relevant for the Peace Corps Volunteer population. We discuss the need for quality data to measure and monitor Volunteers' health progress and outcomes over time, and also to standardize our measurements with Healthy People 2020 benchmarks. This framework may foster greater collaboration to engage in health promotion and disease prevention activities driven by evidence-based information, which may, in turn, encourage healthy behavior among Volunteers.

    The advancement of technologies nowadays enables participation by nonprofessionals, known as volunteers to participate in producing, sharing and consuming geographic information. Such information, termed as volunteered geographic Information (VGI) has created a new approach of gathering geographic information. This paper discusses the traditional way of acquiring geographic information and potentials of VGI as an information source in GIS applications. We also review four commonly cited applications which rely on volunteers for their geographic information based on five criteria; the geometry type available in the applications, availability of user profile, average number of attributes used in the applications, data type of the information (raster or vector) and the domain the application belongs to. This review serves as a preliminarv study in designing a GIS application used for asset management which aims at exploiting volunteers to produce geographic information related to assets

    2003-07-01

    In the frame of the research project RS 1112 'Development of Methods for a Recent Probabilistic Safety Analysis, Particularly Level 2' funded by the German Federal Ministry of Economics and Technology (BMWi), advanced methods, in particular for performing as far as possible realistic plant specific fire risk analyses (fire PSA), should be developed. The present Technical Report gives an overview on the methodologies developed in this context for assessing the fire hazard. In the context of developing advanced methodologies for fire PSA, a probabilistic dynamics analysis with a fire simulation code including an uncertainty and sensitivity study has been performed for an exemplary scenario of a cable fire induced by an electric cabinet inside the containment of a modern Konvoi type German nuclear power plant taking into consideration the effects of fire detection and fire extinguishing means. With the present study, it was possible for the first time to determine the probabilities of specified fire effects from a class of fire events by means of probabilistic dynamics supplemented by uncertainty and sensitivity analyses. The analysis applies a deterministic dynamics model, consisting of a dynamic fire simulation code and a model of countermeasures, considering effects of the stochastics (so-called aleatory uncertainties) as well as uncertainties in the state of knowledge (so-called epistemic uncertainties). By this means, probability assessments including uncertainties are provided to be used within the PSA. (orig.) [de

    2010-10-01

    Despite the importance of fire in shaping savannas, it remains poorly understood how the frequency, seasonality, and intensity of fire interact to influence woody vegetation structure, which is a key determinant of savanna biodiversity. We provide a comprehensive analysis of vertical and horizontal woody vegetation structure across one of the oldest savanna fire experiments, using new airborne Light Detection and Ranging (LiDAR) technology. We developed and compared high-resolution woody vegetation height surfaces for a series of large experimental burn plots in the Kruger National Park, South Africa. These 7-ha plots (total area approximately 1500 ha) have been subjected to fire in different seasons and at different frequencies, as well as no-burn areas, for 54 years. Long-term exposure to fire caused a reduction in woody vegetation up to the 5.0-7.5 m height class, although most reduction was observed up to 4 m. Average fire intensity was positively correlated with changes in woody vegetation structure. More frequent fires reduced woody vegetation cover more than less frequent fires, and dry-season fires reduced woody vegetation more than wet-season fires. Spring fires from the late dry season reduced woody vegetation cover the most, and summer fires from the wet season reduced it the least. Fire had a large effect on structure in the densely wooded granitic landscapes as compared to the more open basaltic landscapes, although proportionally, the woody vegetation was more reduced in the drier than in the wetter landscapes. We show that fire frequency and fire season influence patterns of vegetation three-dimensional structure, which may have cascading consequences for biodiversity. Managers of savannas can therefore use fire frequency and season in concert to achieve specific vegetation structural objectives.

    As a result of the new Clean Air Act, lower NO{sub x} emissions from stationary sources will be required of utilities and independent power producers that burn all fuels including gas, oil and coal. This new legislation, as well as new and more stringent NO{sub x} reduction orders imposed by state and local regulatory agencies, will require rapid evaluation, purchase, installation and start-up of a variety of control technologies. There is substantial volume of literature available discussing NO{sub x} control technologies, their control effectiveness, costs, and chemical reaction mechanisms in forming NO{sub x}. This paper, however, presents more practical aspects of developing a NO{sub x} control strategy and implementing the appropriate cost-effective control technology on a utility or industrial boiler.

    Although the role of volunteers is at the heart of hospice care, little is known about hospice volunteer training and volunteer activity. A survey was used to assess current training programs for hospice volunteers. Hospices were invited to participate in the study from a link on the website for the Hospice Volunteer Association and Hospice Educators Affirming Life Project. Survey results revealed that the majority of volunteer work is in patient care, with most hospice agencies requiring a minimum 12-month volunteer commitment and an average 4-hour volunteer shift per week. Volunteer training is separate from staff training, is provided by paid agency staff, and costs approximately $14,303 per year. Communication and family support are considered important curriculum topics. Revisions to current volunteer training curriculum and format are suggested.

    Forest fire occurs seriously in Vietnam and has been considered as one of the major causes of forest lost and degradation. Several studies of forest fire risk warning were conducted using Modified Nesterov Index (MNI) but remaining shortcomings and inaccurate predictions that needs to be urgently improved. In our study, several important topographic and social factors such as aspect, slope, elevation, distance to residential areas and road system were considered as "permanent" factors while meteorological data were updated hourly using near-real-time (NRT) remotely sensed data (i.e. MODIS Terra/Aqua and TRMM) for the prediction and warning of fire. Due to the limited number of weather stations in Vietnam, data from all active stations (i.e. 178) were used with the satellite data to calibrate and upscale meteorological variables. These data with finer resolution were then used to generate MNI. The only significant "permanent" factors were selected as input variables based on the correlation coefficients that computed from multi-variable regression among true fire-burning (collected from 1/2007) and its spatial characteristics. These coefficients also used to suggest appropriate weight for computing forest fire risk (FR) model. Forest fire risk model was calculated from the MNI and the selected factors using fuzzy regression models (FRMs) and GIS based multi-criteria analysis. By this approach, the FR was slightly modified from MNI by the integrated use of various factors in our fire warning and prediction model. Multifactor-based maps of forest fire risk zone were generated from classifying FR into three potential danger levels. Fire risk maps were displayed using webgis technology that is easy for managing data and extracting reports. Reported fire-burnings thereafter have been used as true values for validating the forest fire risk. Fire probability has strong relationship with potential danger levels (varied from 5.3% to 53.8%) indicating that the higher

    Fire is a significant hazard to the safety of nuclear power plants (NPP). Fire may be serious accident as such, but even small fire at a critical point in a NPP may cause an accident much more serious than fire itself. According to risk assessments a fire may be an initial cause or a contributing factor in a large part of reactor accidents. At the Fire Technology and the the Nuclear Engineering Laboratory of the Technical Research Centre of Finland (VTT) fire safety research for NPPs has been carried out in a large extent since 1985. During years 1988-92 a project Advanced Numerical Modelling in Nuclear Power Plants (PALOME) was carried out. In the project the level of numerical modelling for fire research in Finland was improved by acquiring, preparing for use and developing numerical fire simulation programs. Large scale test data of the German experimental program (PHDR Sicherheitsprogramm in Kernforschungscentral Karlsruhe) has been as reference. The large scale tests were simulated by numerical codes and results were compared to calculations carried out by others. Scientific interaction with outstanding foreign laboratories and scientists has been an important part of the project. This report describes the work of PALOME-project carried out at the Fire Technology Laboratory only. A report on the work at the Nuclear Engineering Laboratory will be published separatively. (au)

    Currently more than 5800 hospice organizations operate in the United States. 1 Hospice organizations are required by the Centers for Medicare and Medicaid Services (CMS) to use volunteers for services provided to patients. 2 Although CMS regulates the amount of hours hospice volunteers should provide, there are currently no national requirements for objectives of training. 3 The purpose of this study was to gather information from a sample of hospices regarding volunteer coordinator background, current training for volunteers, importance of training objectives, and any comments regarding additional objectives. Representative state hospice organizations were contacted by e-mail requesting their participation and distribution of the survey throughout their member hospices. The survey asked demographical questions, along with ratings of training components based on perceived level of importance and time spent on each objective. A total of 90 surveys were received, and the response rate was undeterminable. Results showed the majority of hospices were nonprofit, had less than 100 currently trained volunteers, and maintained an average daily patient census of less than 50. Questions regarding training programs indicated that most use live lecture methods of approximately 19 hours or less in duration. Overall, responding hospice organizations agreed that all objectives surveyed were important in training volunteers. The small number of respondents to this survey makes generalization nationwide difficult, however it is a strong starting point for the development of further surveys on hospice volunteer training and achieving a standardized set of training objectives and delivery methods.

    Since a couple of years, a team at CERN and partners from the Citizen Cyberscience Centre (CCC) have been working on a project that enables general physics simulation programs to run in a virtual machine on volunteer PCs around the world. The project uses the Berkeley Open Infrastructure for Network Computing (BOINC) framework. Based on CERNVM and the job management framework Co-Pilot, this project was made available for public beta-testing in August 2011 with Monte Carlo simulations of LHC physics under the name “LHC at home 2.0” and the BOINC project: “Test4Theory”. At the same time, CERN's efforts on Volunteer Computing for LHC machine studies have been intensified; this project has previously been known as LHC at home, and has been running the “Sixtrack” beam dynamics application for the LHC accelerator, using a classic BOINC framework without virtual machines. CERN-IT has set up a BOINC server cluster, and has provided and supported the BOINC infrastructure for both projects. CERN intends to evolve the setup into a generic BOINC application service that will allow scientists and engineers at CERN to profit from volunteer computing. This paper describes the experience with the two different approaches to volunteer computing as well as the status and outlook of a general BOINC service.

    2017-01-01

    Paramedics require a wide range of skills that are beyond clinical or technical skills in order to meet the demands of the role and provide quality and compassionate care to patients. Non-technical or "soft" skills and attributes are generally challenging to teach and develop in the classroom setting. Volunteerism provides an opportunity for students to gain exposure to different communities and develop interpersonal skills. This cross-sectional study used one-on-one interviews with 12 third-year Bachelor of Emergency Health (Paramedic) students from Monash University, Australia, who completed a community volunteering program. Results suggest that paramedic students see volunteering as a highly valuable means of developing a number of skills crucial to their future roles and paramedic practice. Volunteering also provided students with an opportunity to learn about themselves and the broader community, develop confidence, and improve overall job-readiness and employability. This study demonstrates that embedding volunteering into paramedic education is an effective way to develop the broad range of paramedic attributes required for the role. These experiences allow students to make the important transition to a job-ready graduate paramedic who can provide holistic patient-centred care.

    Members of the Directorate and their support staff took part in a fire-fighting course organised by the CERN Fire Brigade just before the end-of-year break.  The Bulletin takes a look at the fire-fighting training on offer at CERN.   At CERN the risk of fire can never be under-estimated. In order to train personnel in the use of fire extinguishers, CERN's fire training centre in Prévessin acquired a fire-simulation platform in 2012. On the morning of 17 December 2012, ten members of the CERN directorate and their support staff tried out the platform, following in the footsteps of 400 other members of the CERN community who had already attended the course. The participants were welcomed to the training centre by Gilles Colin, a fire-fighter and instructor, who gave them a 30-minute introduction to general safety and the different types of fire and fire extinguishers, followed by an hour of practical instruction in the simulation facility. There they were able to pract...

    1979-01-01

    The gloveboxes used for plutonium facilities in Japan and foreign countries have considerable combustibles as their components, so that the fire resistivity of the gloveboxes is a serious problem in the safety evaluation of the facilities. Actually, a big fire having burned gloveboxes occurred in a foreign weapon facility. But the fire in the weapon facility should be distinguished from that in nuclear fuel facilities, since the former handles quite combustible plutonium metal, while the latter handle quite stable plutonium oxide. The countermeasures to fires should be decided, considering the properties and quantity of combustibles around gloveboxes and ventilation systems, as the probability and scale of fires can be presumed from them. From the viewpoint of safety, the experiment on glovebox fires was carried out by the Plutonium Fuel Division, PNC. The experimental conditions are explained. The samples were the acrylic resin panels with four glove ports and a small glovebox currently used. The glovebox showed the considerable fire resistance, and the panel hardly burned. The weakest component of the glovebox against fire was the gloves. The countermeasure to curtain the gloves with an insulating material seemed to be effective. The ventilation of the room and the glovebox worked as fire preventer at least in the first stage of fire. (Kako, I.)

    Science.gov (United States)

    Lavenburg, Philip; Bernt, Frank M

    2012-08-01

    We surveyed volunteers from 8 hospices in the Delaware Valley regarding training, perceived needs, and role satisfaction. Results were consistent with previous studies: satisfaction with preservice training and with volunteering was very high; respondents reported feeling very prepared and confident about doing hospice work as a result of their volunteer training. In addition, longer volunteer preservice training was associated with higher levels of overall satisfaction with training; levels of volunteer satisfaction and fulfillment tended to be lower during the first year of volunteering; and participation in volunteer support teams was associated with finding volunteer work rewarding and with feeling a part of the hospice team. Implications for preservice training and ongoing support and education of hospice volunteers are discussed.

    Full Text Available Abstract Background Despite statements from national fire service organizations, including the International Association of Fire Fighters (IAFF and the International Association of Fire Chiefs (IAFC, promoting a diverse work force related to gender within the fire service, rates of women firefighters remain very low. Thus, research into why this extensive gender disparity continues is a high priority. Recent years have seen a number of large scale studies on firefighter health and health risk behaviors however, none have focused on the health of women firefighters and nearly all have eliminated women from the sample due to small sample size. Data from the present report is drawn from all females in a large, randomly selected cohort of firefighters in an epidemiological study designed to assess health outcomes and health risk behaviors identified as most important to the fire service. Methods Data reported for the present study were collected as baseline data for the Firefighter Injury and Risk Evaluation (FIRE Study, a longitudinal cohort study examining risk factors for injury in both career and volunteer firefighters in the IAFC Missouri Valley Region. Of the departments assessed, only 8 career and 6 volunteer departments had any women firefighters. All the women solicited for participation chose to enroll in the study. The number of women ranged from 1 to 7 in career departments and 1 to 6 in volunteer departments. Results Where possible, comparisons are made between female firefighters and published data on male firefighters as well as comparisons between female firefighters and military members. Compared to male firefighters, females had more favorable body composition among both career and volunteer firefighters. Tobacco use rates were generally higher among females than males and rates among female firefighters were similar to the rates of female military members. While rates of alcohol use were higher than the general population, only

    Automated early fire detection systems have recently received a significant amount of attention due to their importance in protecting the global environment. Some emergent technologies such as ground-based, satellite-based remote sensing and distributed sensor networks systems have been used to detect forest fires in the early stages. In this study, a radio-acoustic sounding system with fine space and time resolution capabilities for continuous monitoring and early detection of forest fires is proposed. Simulations show that remote thermal mapping of a particular forest region by the proposed system could be a potential solution to the problem of early detection of forest fires.

  10. Who will volunteer? Analysing individual and structural factors of volunteering in Swiss sports clubs.

    Science.gov (United States)

    Schlesinger, Torsten; Nagel, Siegfried

    2013-01-01

    This article analyses the conditions influencing volunteering in sports clubs. It focuses not only on individual characteristics of volunteers but also on the corresponding structural conditions of sports clubs. It proposes a model of voluntary work in sports clubs based on economic behaviour theory. The influences of both the individual and context levels on the decision to engage in voluntary work are estimated in different multilevel models. Results of these multilevel analyses indicate that volunteering is not just an outcome of individual characteristics such as lower workloads, higher income, children belonging to the sports club, longer club memberships, or a strong commitment to the club. It is also influenced by club-specific structural conditions; volunteering is more probable in rural sports clubs whereas growth-oriented goals in clubs have a destabilising effect.

    To solve the water wall overheating in lower furnace, and further reduce NOx emissions and carbon in fly ash, continuous improvement of the previously proposed multiple injection and multiple staging combustion (MIMSC) technology lies on three aspects: (1) along the furnace arch breadth, changing the previously centralized 12 burner groups into a more uniform pattern with 24 burners; (2) increasing the mass ratio of pulverized coal in fuel-rich flow to that in fuel-lean flow from 6:4 to 9:1; (3) reducing the arch-air momentum by 23% and increasing the tertiary-air momentum by 24%. Industrial-size measurements (i.e., adjusting overfire air (OFA) damper opening of 20-70%) uncovered that, compared with the prior MIMSC technology, the ignition distance of fuel-rich coal/air flow shortened by around 1 m. The gas temperature in the lower furnace was symmetric and higher, the flame kernel moved upward and therefore made the temperature in near-wall region of furnace hopper decrease by about 400 °C, the water wall overheating disappeared completely. Under the optimal OFA damper opening (i.e, 55%), NOx emissions and carbon in fly ash attained levels of 589 mg/m(3) at 6% O2 and 6.18%, respectively, achieving NOx and carbon in fly ash significant reduction by 33% and 37%, respectively.

    The periodic occurrence of large-scale, potentially disastrous industrial accidents involving fire in hazardous environments such as oilwell blowouts, petrochemical explosions and nuclear installations highlights the need for an integrated approach to fire safety engineering. Risk reduction 'by design' and rapid response are of equal importance in the saving of life and property in such situations. This volume of papers covers the subject thoroughly, touching on such topics as hazard analysis, safety design and testing, fire detection and control, and includes studies of fire hazard in the context of environment protection.

    The first Specialists' Meeting on sodium fire technology sponsored by the International Working Group on Fast Reactors (IWGFR) was held in Richland, Washington in 1972. The group concluded that the state-of-technology at that time was inadequate to support the growing LMFBR industry. During the second IWGFR Specialists' Meeting on sodium fires, held in Cadarache, France in 1978, a large quantity of technical information was exchanged and areas were identified where additional work was needed. Advances in several important areas of sodium fire technology have been made in the United States since that time, including improved computer codes, design of a sodium fire protection system for the CRBRP, measurement of water release from heated concrete, and testing and modeling of the sodium-concrete reaction. Research in the U.S. related to sodium fire technology is performed chiefly at the Energy Systems Group of Rockwell International (including Atomics International), the Hanford Engineering Development Laboratory (HEDL), and the Sandia National Laboratories (SNL). The work at the first two laboratories is sponsored by the U.S. Department of Energy, while that at the latter is sponsored by the U.S. Nuclear Regulatory Commission. Various aspects of sodium fire related work is also performed at several other laboratories. The current status of sodium fire technology in the U.S. is summarized in this report

    We describe, for the first time, the design, production and evaluation of large microneedle patches. Such systems, based on 16 individual microneedle arrays (needle height 600μm), were prepared from aqueous blends of 15% w/w Gantrez ® S97 and 7.5% w/w poly(ethyleneglycol) 10,000Da. Ester-based crosslinking was confirmed by FTIR and mechanical strength was good. Insertion depths in a validated skin model were approximately 500μm. Ten human volunteers successfully self-inserted the microneedles of these larger patches in their skin, following appropriate instruction, as confirmed by transepidermal water loss measurements. The mean insertion depth ranged between 300 and 450μm over the area of the large patches. That this was not significantly different to a single unit MN patch self-applied by the same volunteers is encouraging. Microneedle patch sizes much larger than the 1-2cm 2 will be required if this technology is to be successfully translated to clinic for delivery of drug substances. The work described here suggests that use of such larger patches by patients can be successful, potentially opening up the possibility for a significant expansion of the size of the market for transdermal drug delivery.

    The safety of Ammunition has always been the focus of national military science and technology issues. And fire is one of the major safety threats to the ship’s ammunition storage environment, In this paper, Mk-82 shipborne aviation bomb has been taken as the study object, simulated the whole process of fire by using the FDS (Fire Detection System) software. According to the simulation results of FDS, ANSYS software was used to simulate the temperature field of Mk-82 carrier-based aviation bomb under fire environment, and the safety of aviation bomb in fire environment was analyzed. The result shows that the aviation bombs under the fire environment can occur the combustion or explosion after 70s constant cook-off, and it was a huge threat to the ship security.

    Development of video, computing technologies and computer vision gives a possibility of automatic fire detection on video information. Under that project different algorithms was implemented to find more efficient way of fire detection. In that article colour based fire detection algorithm is described. But it is not enough to use only colour information to detect fire properly. The main reason of this is that in the shooting conditions may be a lot of things having colour similar to fire. A temporary intensity variation of pixels is used to separate them from the fire. These variations are averaged over the series of several frames. This algorithm shows robust work and was realised as a computer program by using of the OpenCV library

    Coal-based power generation systems provide reliable, low-cost power to the domestic energy sector. These systems consume large amounts of fuel and water to produce electricity and are the target of pending regulations that may require reductions in water use and improvements in thermal efficiency. While efficiency of coal-based generation has improved over time, coal power plants often do not utilize the low-grade heat contained in the flue gas and require large volumes of water for the steam cycle make-up, environmental controls, and for process cooling and heating. Low-grade heat recovery is particularly challenging for coal-fired applications, due in large part to the condensation of acid as the flue gas cools and the resulting potential corrosion of the heat recovery materials. Such systems have also not been of significant interest as recent investments on coal power plants have primarily been for environmental controls due to more stringent regulations. Also, in many regions, fuel cost is still a pass-through to the consumer, reducing the motivation for efficiency improvements. Therefore, a commercial system combining low-grade heat-recovery technologies and associated end uses to cost effectively improve efficiency and/or reduce water consumption has not yet been widely applied. However, pressures from potential new regulations and from water shortages may drive new interest, particularly in the U.S. In an effort to address this issue, the U.S. Department of Energy (DOE) has sought to identify and promote technologies to achieve this goal.

  4. Research on the fire alarming system of fiber grating

    2007-09-01

    The application of fiber grating sensing technology in fire alarming based on temperature detection has the advantages of high accuracy, high reliability and strong immunity from electronic and magnetic fields. It is especially advantageous to use this system in the petroleum and chemistry industry because it can provide an extraordinary safe means for the fire alarm. But due to the traditional optical Wavelength Division Multiplexing (WDM) technology is limited by the optic source bandwidth, the number of its multiplexing points is few. In this paper WDM technology will be developed mixing with Identified Bragg, which is called Identified and Wavelength Multiplexing, to build the Fiber Grating (FBG) fire alarm system integrated with computers. Some technologies applied in fire alarming system of fiber grating such as the transmission of test signals which pass through modulate and demodulate, the disposal of software system, the output of control signal and the strong ability of anti-disturbance have been studied and discussed.

In new high rise buildings the fire safety of facades can be taken into account by means of performance based fire design that can help in the selection of the best technological solutions and material choices. This article deals with a case study done on the Piedmont Region Headquarters (TORRE REGIONE PIEMONTE which is one of the highest office buildings in Italy. The “Torre Regione Piemonte” is located in Turin and has 45 storey and a total height of 183,61 m. The building is characterized by the closed enclosure called “Grand Space” which is continuous for almost the entire height of the building and contains volumes such as offices/meeting rooms named as “Satellites”. In order to fulfil Italian fire safety requirements, the “Torre Regione Piemonte” building has been assessed using the performance base design and fire safety engineering approach. This paper deals with the design process selection of the most representative fire scenarios focusing on the fire resistance performance requirements of structural and glazed elements of the facades. Furthermore, all the simulation, calculations and performance fire resistant requirements of the high rise building have been supported by specific laboratory tests and experimental results, that are reported and discussed within paper.

    For a successful fire suppression, it is essential to detect and intervene forest fires as early as possible. Fire lookout towers are crucial assets in detecting forest fires, in addition to other technological advancements. In this study, we performed a visibility analysis on a network of fire lookout towers currently operating in a relatively fire-prone region in Turkey's Western Black Sea region. Some of these towers had not been functioning properly; it was proposed that these be taken out of the grid and replaced with new ones. The percentage of visible areas under the current network of fire lookout towers was 73%; it could rise to 81% with the addition of newly proposed towers. This study was the first research to conduct a visibility analysis of current and newly proposed fire lookout towers in the Western Black Sea region and focus on its forest fire problem.

    The activity concentration (AC) of TENORM - 238 U, 226 Ra ( 238 U series), 232 Th, 228 Ra, 228 Th ( 232 Th series) and 40 K in feed coal, bottom ash and fly ash samples from four coal-fired thermal power plants C, M, P and S were determined using two techniques: inductively coupled plasma mass spectrometry (ICP-MS) and high purity germanium (HPGe) gamma spectrometry. For 232 Th and 238 U [determined at National Institute for Radiological Sciences (NIRS) by the ICP-MS)], Plant S feed coal (FC) sample that originated from China had the highest AC (15.77 ± 0.32 Bq/kg and 13.67 ± 0.82 Bq/kg, respectively), followed by Plant M FC sample also from China (8.31 ± 0.33 Bq/kg and 5.84 ± 0.12 Bq/kg, respectively), while Plants C and P FC samples that originated from the Philippines and Indonesia had the lowest ACs of 232 Th and 238 U. Plant S also had the highest bottom ash (BA) AC of 80.86 ± 3.23 Bq/kg and 100.20 ± 4.01 Bq/kg, respectively while Plant P had the highest fly ash (FA) AC of 155.96 ± 6.24 Bq/kg and 268.03 ± 10.72 Bq/kg, respectively. For AC's of 226 Ra, 228 Ra, 228 Th and 40 K determined by NIRS HPGe, Plant C had the highest in the FC sample (11.70 ± 1.39 Bq/kg, 13.65 ± 4.99 Bq/kg, 11.35 ± 3.96 Bq/kg ad 80.23 ± 10.91 Bq/kg, respectuvely). For AC's in the BA samples, Plant M had the highest 226 Ra (106.73 ± 6.74 Bq/kg) and Plant S had the highest 228 Ra and 40 K (66.64 ± 8.16 Bq/kg and 400.93 ± 43.06 Bq/kg, respectively For AC's in the FA samples, Plant S had the highest 226 Ra and 228 Ra AC's (131.13 ± 8.09 Bq/kg and 87.70 ± 10.45 Bq/kg, respectively) while Plant C had the highest 40 K AC (369.08 ± 40.87 Bq/kg). The highest AC enhancement of 238 U, 226 Ra ( 238 U series), 232 Th, 228 Ra, 228 Th ( 232 Th series) 40 K relative to feed coal occurred in Plant P FA sample, with 238 U showing the highest enhancement of 93.72 among the radionuclides. When normalized with 40 K, 238 U in Plant P FA sample also had the highest enrichment factor (EF

  18. Defecographic findings of young asymptomatic volunteers

    1994-01-01

    Defacography is a technique of examining the rectum and anal canal by using fluoroscopy during detection. This study was done to determine the range of normal findings of defecography in young asymptomatic Korean volunteers. Twenty nine asymptomatic young volunteers underwent defecography. Anorectal angle, perineal descent, length and width of anal, rectocele, rectal intussusception and incontinence were evaluated. The range of anorectal angle was 82 .deg- 149 .deg in resting state, compared to the 63 .deg-116 .deg in squeezing state, and 95 .deg- 116 .deg in straining state respectively. The pelvic floor in straining state descended on average of 1.62 cm from the inferior margin of ischial tuberosity that its broad range of position from-5.2 cm to 0.8 cm implies a wide variation of anorectal angle and perineal descent. Mild degree of rectocele with less than 2 cm of depth was found in 12 out of 29 cases. Rectal intussusception was noted in six and rectal incontinence was seen in one case. Formation of rectocele and intussusception during defecation was common in asymptomatic young volunteers. The wide range of defacographic measurements warrants the necessity of other complementary studies on anorectal function to improve the diagnostic accuracy. The interpretation of defecographic measurement should therefore be made with caution and should not be used as the sole criteria for selection of treatment modality

    The aim of our prospective study was to define endoscopy appearance of the small bowel in healthy volunteers. Forty-two healthy volunteers underwent wireless capsule endoscopy, clinical investigation, laboratory tests, and completed a health-status questionnaire. All subjects were available for a 36-month clinical follow-up. Eleven subjects (26%) had fully normal endoscopy findings. Remaining 31 persons (74%), being asymptomatic, with normal laboratory results, had some minor findings at wireless capsule endoscopy. Most of those heterogeneous findings were detected in the small intestine (27/31; 87%), like erosions and/or multiple red spots, diminutive polyps and tiny vascular lesions. During a 36-month clinical follow-up, all these 42 healthy volunteers remained asymptomatic, with fully normal laboratory control. Significant part of healthy subjects had abnormal findings at wireless capsule endoscopy. These findings had no clinical relevance, as all these persons remained fully asymptomatic during a 36-month follow-up. Such an endoscopic appearance would be previously evaluated as "pathological". This is a principal report alerting that all findings of any control group of wireless capsule endoscopic studies must be evaluated with caution.

  4. The enrichment of natural radionuclides in oil shale-fired power plants in Estonia – The impact of new circulating fluidized bed technology

    2014-01-01

    Burning oil shale to produce electricity has a dominant position in Estonia's energy sector. Around 90% of the overall electric energy production originates from the Narva Power Plants. The technology in use has been significantly renovated – two older types of pulverized fuel burning (PF) energy production units were replaced with new circulating fluidized bed (CFB) technology. Additional filter systems have been added to PF boilers to reduce emissions. Oil shale contains various amounts of natural radionuclides. These radionuclides concentrate and become enriched in different boiler ash fractions. More volatile isotopes will be partially emitted to the atmosphere via flue gases and fly ash. To our knowledge, there has been no previous study for CFB boiler systems on natural radionuclide enrichment and their atmospheric emissions. Ash samples were collected from Eesti Power Plant's CFB boiler. These samples were processed and analyzed with gamma spectrometry. Activity concentrations (Bq/kg) and enrichment factors were calculated for the 238 U ( 238 U, 226 Ra, 210 Pb) and 232 Th ( 232 Th, 228 Ra) family radionuclides and for 40 K in different CFB boiler ash fractions. Results from the CFB boiler ash sample analysis showed an increase in the activity concentrations and enrichment factors (up to 4.5) from the furnace toward the electrostatic precipitator block. The volatile radionuclide ( 210 Pb and 40 K) activity concentrations in CFB boilers were evenly distributed in finer ash fractions. Activity balance calculations showed discrepancies between input (via oil shale) and output (via ash fractions) activities for some radionuclides ( 238 U, 226 Ra, 210 Pb). This refers to a situation where the missing part of the activity (around 20% for these radionuclides) is emitted to the atmosphere. Also different behavior patterns were detected for the two Ra isotopes, 226 Ra and 228 Ra. A part of 226 Ra input activity, unlike 228 Ra, was undetectable in the solid

    A study in modeling fire hazard assessment will be essential in establishing an effective forest fire management system especially in controlling and preventing peat fire. In this paper, we have used geographic information system (GIS), in combination with other geoinformation technologies such as remote sensing and computer modeling, for all aspects of wild land fire management. Identifying areas that have a high probability of burning is an important component of fire management planning. The development of spatially explicit GIS models has greatly facilitated this process by allowing managers to map and analyze variables contributing to fire occurrence across large, unique geographic units. Using the model and its associated software engine, the fire hazard map was produced. Extensive avenue programming scripts were written to provide additional capabilities in the development of these interfaces to meet the full complement of operational software considering various users requirements. The system developed not only possesses user friendly step by step operations to deliver the fire vulnerability mapping but also allows authorized users to edit, add or modify parameters whenever necessary. Results from the model can support fire hazard mapping in the forest and enhance alert system function by simulating and visualizing forest fire and helps for contingency planning.

    Recent improvements in online information communication and mobile location-aware technologies have led to the production of large volumes of volunteered geographic information. Widespread, large-scale efforts by volunteers to collect data can inform and drive scientific advances in diverse fields, including ecology and climatology. Traditional workflows to check the quality of such volunteered information can be costly and time consuming as they heavily rely on human interventions. However, identifying factors that can influence data quality, such as inconsistency, is crucial when these data are used in modeling and decision-making frameworks. Recently developed workflows use simple statistical approaches that assume that the majority of the information is consistent. However, this assumption is not generalizable, and ignores underlying geographic and environmental contextual variability that may explain apparent inconsistencies. Here we describe an automated workflow to check inconsistency based on the availability of contextual environmental information for sampling locations. The workflow consists of three steps: (1) dimensionality reduction to facilitate further analysis and interpretation of results, (2) model-based clustering to group observations according to their contextual conditions, and (3) identification of inconsistent observations within each cluster. The workflow was applied to volunteered observations of flowering in common and cloned lilac plants (Syringa vulgaris and Syringa x chinensis) in the United States for the period 1980 to 2013. About 97% of the observations for both common and cloned lilacs were flagged as consistent, indicating that volunteers provided reliable information for this case study. Relative to the original dataset, the exclusion of inconsistent observations changed the apparent rate of change in lilac bloom dates by two days per decade, indicating the importance of inconsistency checking as a key step in data quality

    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 ...

    Xin, Y.; Cervone, G.

    2017-12-01

    Volunteered Geographic Information (VGI), defined as geographic information contributed voluntarily by amateurs, have grown exponentially nowadays with the aid of ubiquitous GPS-enabled telecommunication technologies. VGI projects, like Wikimapia, OpenStreetMap, Flickr and Safecast have shown remarkable success on leveraging citizen science to increase our knowledge about the geographic world. However, in spite of its growing popularity, VGI is still facing the most challenging problem of ensuring data quality. In this study, we proposed a methodology to filter outliers in Safecast measurements through cross-reference among volunteers. Based on the outliers filtered, a trust index is generated for each volunteer. The results are validated using official radiation measurements surveyed by Department of Energy. The validation shows that removing the outliers filtered by our methodology, Safecast measurements yield a better correlation with official measurements.

    Results of experiments carried out with sodium fires to develop extinguishment techniques are presented. Characteristics, ignition temperature, heat evolution and other aspects of sodium fires are described. Out of the powders tested for extinguishment of 10 Kg sodium fires, sodium bi-carbonate based dry chemical powder has been found to be the best extinguisher followed by large sized vermiculite and then calcium carbonate powders distributed by spray nozzles. Powders, however, do not extinguish large fires effectively due to sodium-concrete reaction. To control large scale fires in a LMFBR, collection trays with protective cover have been found to cause oxygen starvation better than flooding with inert gas. This system has an added advantage in that there is no damage to the sodium facilities as has been in the case of powders which often contain chlorine compounds and cause stress corrosion cracking.

    2010-10-01

    This study tested a theoretical model of volunteering benefits and examined the mechanism through which volunteering benefits older adults. This is a 2-wave study of 253 older adult volunteers serving in 10 volunteer programs. Older volunteers completed the mailed surveys in 2005 and 2006. Structural equation modeling was used to define the latent variables and to test direct and indirect relationships among organizational support, socioemotional benefits, and self-reported health. Organizational support (measured by choice of volunteer activity, training, and ongoing support) had significant direct associations with 2 latent factors of socioemotional benefits, that is, perceived contribution and personal benefits. Perceived contribution was significantly related to mental health. Additionally, older volunteers with lower socioeconomic status (SES) committed more hours and perceived more personal benefits than higher SES peers. These findings suggest that volunteer programs can provide various organizational supports to older volunteers, especially to low-SES volunteers, in order to promote the socioemotional and health benefits of volunteering to older adults. Psychological well-being of older adults can be improved through engagement in meaningful volunteer activities and contribution to others.

  4. The principles for creation of fire-prevention forest belts with barriers of deciduous species for protection from crown fires

    Directory of Open Access Journals (Sweden)

    S. N. Sannikov

    2017-10-01

    Full Text Available The article discuss one of the priority security problems in Russia, which is elaboration of the strategic system of the forest and society safeguards from catastrophic forest crown fires in connection with rapid climate warming. It is postulated, that a most effective and reliable barrier for the dispersal of the intensive crown fire in a coniferous forest massive can be a sufficiently wide strip of deciduous tree species – «deciduous forest barrier», which has phytomass capable of absorbing crown fire energy and transforming them to surface fire, which may be extinguished by technical means. The actuality of the natural study of the transition parameters from the crown fire to surface fire has been noted, depending on climate, fire intensity and the deciduous barrier structure. The results of the quantitative natural investigation of the consequences of catastrophic crown fires of 2004 in the island pine forests of forest-steppe zone in Kurgan Oblast, which passed through the belt of 50–70 year-old birch stands of middle density, has been cited and formalized mathematically. It has been shown, that 150 m width of deciduous forest barrier is necessary as a minimum for the reliable transition of the high intensive front crown fire to surface fire in the forest-steppe conditions of the Western Siberia, but this width reduces with a decreasing heating effect. It has been proposed to create the complex fire-prevention forest belts of different construction for the protection of forests, industrial objects and settlements. Besides a basic deciduous barrier, their structure should include technologically necessary buffer zones and zones for the localization and extinguishing surface fire, which stop a crown fire. It has been recommended to use natural regeneration of deciduous tree species, as a most effective and non-deficient method for the creation of deciduous forest barriers in the predominant forest types, except the lichen pine forests

    2017-01-01

    Full Text Available The research introduces a methodology of establishing indicators of fire safety of a building in relation to a guaranteed duration of steel fire-proof corrugated beams resistance in conditions of standard fire tests. Indicators of fire safety are also established in the assessment of design limits of steel fire-proof corrugated beams during design process, construction or maintenance of the building as well as in reducing economic costs when testing steel structures for fire resisting property. The suggested methodology introduces the system of actions aimed to design constructive fire protection of steel corrugated beams of buildings. Technological effect is achieved by conducting firing tests of steel construction by non-destructive methods; the evaluation of fire resistance of fire-proof elements of corrugated beams (corrugated web, upper and lower shelves is identified by the least fire-proof element of a welded I-beam. In this methodology fire resistance duration of the constituent elements of a welded I-beam with account of its fire protection ability is described with an analytic function taken as variables. These variables are intensity strength of stresses and the degree of fire protection of a compound element.

    Science.gov (United States)

    Wei, Ying-Zhuo; Zhang, Shao-Wu; Liu, Yan-Wei

    2010-04-01

    Smoke detection is very important for preventing forest-fire in the fire early process. Because the traditional technologies based on video and image processing are easily affected by the background dynamic information, three limitations exist in these technologies, i. e. lower anti-interference ability, higher false detection rate and the fire smoke and water fog being not easily distinguished. A novel detection method for detecting smoke based on the multispectral image was proposed in the present paper. Using the multispectral digital imaging technique, the multispectral image series of fire smoke and water fog were obtained in the band scope of 400 to 720 nm, and the images were divided into bins. The Euclidian distance among the bins was taken as a measurement for showing the difference of spectrogram. After obtaining the spectral feature vectors of dynamic region, the regions of fire smoke and water fog were extracted according to the spectrogram feature difference between target and background. The indoor and outdoor experiments show that the smoke detection method based on multispectral image can be applied to the smoke detection, which can effectively distinguish the fire smoke and water fog. Combined with video image processing method, the multispectral image detection method can also be applied to the forest fire surveillance, reducing the false alarm rate in forest fire detection.

    Energy Technology Data Exchange (ETDEWEB)

    1994-07-01

    This study was one of a group of assessments of toxic emissions from coal-fired power plants, conducted for DOE during 1993. The motivation for those assessments was the mandate in the 1990 Clean Air Act Amendments that a study be made of emissions of hazardous air pollutants (HAPs) from electric utilities. The report is organized in two volumes. Volume 1: Sampling describes the sampling effort conducted as the basis for this study; Results presents the concentration data on HAPs in the several power plant streams, and reports the results of evaluations and calculations conducted with those data; and Special Topics report on issues such as comparison of sampling methods and vapor/solid distributions of HAPs. Volume 2: Appendices include quality assurance/quality control results, uncertainty analysis for emission factors, and data sheets. This study involved measurements of a variety of substances in solid, liquid, and gaseous samples from input, output, and process streams at the Innovative Clean Coal Technology Demonstration (ICCT) of the Wet Sulfuric Acid-Selective Catalytic Reduction (SNOX) process. The SNOX demonstration is being conducted at Ohio Edison`s Niles Boiler No. 2 which uses cyclone burners to burn bituminous coal. A 35 megawatt slipstream of flue gas from the boiler is used to demonstrate SNOX. The substances measured at the SNOX process were the following: 1. Five major and 16 trace elements, including mercury, chromium, cadmium, lead, selenium, arsenic, beryllium, and nickel; 2. Acids and corresponding anions (HCl, HF, chloride, fluoride, phosphate, sulfate); 3. Ammonia and cyanide; 4. Elemental carbon; 5. Radionuclides; 6. Volatile organic compounds (VOC); 7. Semi-volatile compounds (SVOC) including polynuclear aromatic hydrocarbons (PAH); and 8. Aldehydes.

  17. Widely Assumed but Thinly Tested: Do Employee Volunteers' Self-Reported Skill Improvements Reflect the Nature of Their Volunteering Experiences?

    2016-01-01

    An increasing number of companies use corporate volunteering programs (CVPs) to support and coordinate their employees' efforts to serve their communities. Among the most frequently touted benefits of such programs to sponsoring companies and employee volunteers alike is the opportunities for employees to develop tangible work-related skills through their volunteering activities. Evidence for skill development through volunteering, however, is mostly limited to the expressed beliefs of corporate leaders and employee volunteers. This study was designed to contribute to this largely anecdotal literature by testing hypotheses about the extent to which employee volunteers' self-reported skill development reflects the characteristics of the volunteers and their volunteering experiences. Study participants were 74 employee volunteers who completed a service apprenticeship managed by a U.S.-based nonprofit called Citizen Schools that partners with middle schools to extend the learning day with a combination of academic support, enrichment, and youth development activities. Data were obtained via the nonprofit's records, and surveys completed by employee volunteers before and after their service experience, including measures used to assess self-reported improvements in each of 10 work-related skills: communicating performance expectations, leadership, mentorship, motivating others, project management, providing performance feedback, public speaking and presenting, speaking clearly, teamwork, and time management. Support was found for several hypothesized effects suggesting that employees who practiced specific skills more often during their volunteering experience reported greater improvements in those skills. Improvements in some skills were higher among employee volunteers who completed a greater number of pre-volunteering preparation courses, and the effects of preparation courses were moderated by the employee volunteers' self-efficacy about improving their work

    Harmful algal blooms of the dinoflagellate Karenia brevis can cause massive fish-kills and marine mammal mortalities, as well as impact human health via the consumption of brevetoxin-contaminated shellfish and the inhalation of aerosolized toxins. There is a strong effort to predict human health impacts by monitoring the bloom stages of K. brevis, and to prevent health impacts by closing shellfish beds when K. brevis cell concentrations reach toxic levels. The current standard method for quantifying K. brevis is by microscopic enumeration, which requires taxonomic expertise to discern K. brevis cells from other Karenia species as well as a long turnover time to generate data, which limits the number of water samples that can be processed. This EPA-funded study compared a variety of technologies against the current standard (microscopic counts) to quantify the number of K. brevis cells per liter in the water column. Results of this study showed a strong correlation between Real Time Nucleic Acid Sequence-Based Amplification (RT-NASBA) and enumeration by microscopy performed by members of the Florida Fish and Wildlife Research Institute, who are responsible for such monitoring. We are adapting the bench-top RT-NASBA assay to the AmpliFire platform (a handheld sensor that can be used in the field), for point of need K. brevis detection. These handheld sensors will be used by a trained volunteer network and government agencies (FWC, NOAA, and Mote Marine Lab.) to quantify K. brevis cells in the water column of core Gulf of Mexico sites; the results from these sensors will be reported back to the GCOOS observation systems to provide real-time monitoring of K. brevis counts. The real-time information will allow agencies to better monitor fishery closures and predict human health impacts of harmful algal blooms, because a larger number of samples can be processed each week, as the NASBA process removes the rate-limiting step of microscope time.

    The purpose of this fire hazards analysis (FHA) is to assess the risk from fire within individual fire areas at the Busted Butte Test Facility and to ascertain whether the DOE fire safety objectives are met. The objective, identified in DOE Order 420.1, Section 4.2, is to establish requirements for a comprehensive fire and related hazards protection program for facilities sufficient to minimize the potential for: (1) The occurrence of a fire related event. (2) A fire that causes an unacceptable on-site or off-site release of hazardous or radiological material that will threaten the health and safety of employees. (3) Vital DOE programs suffering unacceptable interruptions as a result of fire and related hazards. (4) Property losses from a fire and related events exceeding limits established by DOE.

  9. Evolutionary stability in the asymmetric volunteer's dilemma.

    Directory of Open Access Journals (Sweden)

    Jun-Zhou He

    Full Text Available It is often assumed that in public goods games, contributors are either strong or weak players and each individual has an equal probability of exhibiting cooperation. It is difficult to explain why the public good is produced by strong individuals in some cooperation systems, and by weak individuals in others. Viewing the asymmetric volunteer's dilemma game as an evolutionary game, we find that whether the strong or the weak players produce the public good depends on the initial condition (i.e., phenotype or initial strategy of individuals. These different evolutionarily stable strategies (ESS associated with different initial conditions, can be interpreted as the production modes of public goods of different cooperation systems. A further analysis revealed that the strong player adopts a pure strategy but mixed strategies for the weak players to produce the public good, and that the probability of volunteering by weak players decreases with increasing group size or decreasing cost-benefit ratio. Our model shows that the defection probability of a "strong" player is greater than the "weak" players in the model of Diekmann (1993. This contradicts Selten's (1980 model that public goods can only be produced by a strong player, is not an evolutionarily stable strategy, and will therefore disappear over evolutionary time. Our public good model with ESS has thus extended previous interpretations that the public good can only be produced by strong players in an asymmetric game.

    Since a couple of years, a team at CERN and partners from the Citizen Cyberscience Centre (CCC) have been working on a project that enables general physics simulation programs to run in a virtual machine on volunteer PCs around the world. The project uses the Berkeley Open Infrastructure for Network Computing (BOINC) framework. Based on CERNVM and the job management framework Co-Pilot, this project was made available for public beta-testing in August 2011 with Monte Carlo simulations of LHC physics under the name "LHC@home 2.0" and the BOINC project: "Test4Theory". At the same time, CERN's efforts on Volunteer Computing for LHC machine studies have been intensified; this project has previously been known as LHC@home, and has been running the "Sixtrack" beam dynamics application for the LHC accelerator, using a classic BOINC framework without virtual machines. CERN-IT has set up a BOINC server cluster, and has provided and supported the BOINC infrastructure for both projects. CERN intends to evolve the setup i...

  11. Surface Accessibility with Spatial Analysis During Fire Extinguishing Procedures: Example on the Island of Vis

    Directory of Open Access Journals (Sweden)

    Kruno Lepoglavec

    2017-01-01

    Full Text Available Background and Purpose: The existing public and forest transport infrastructure (truck forest roads are permanent objects used when passing through forests. They also serve as a firefighter belt and provide direct access to firefighting vehicles, or are used as the starting point where firefighting teams extinguish fires or move toward remote fires. The paper identifies the existing fire road network (including public roads, forest roads, non-classified roads and fire roads for access of firefighting vehicles during fire extinguishing interventions. Material and Methods: An analysis of the intervention rate was conducted on a dispersive sample (35 positions from two volunteer fire associations (VFA on the island of Vis. Also, an analysis of the surface availability to fire vehicles concerning the time of departure from the fire station was conducted, as well as the comparison with the Standard time of intervention defined by the regulations on fire department organization in the Republic of Croatia. Results: For each simulated fire location for intervention of two existing volunteer fire associations: VFA Komiža and VFA Vis, results show that for a few fire locations, despite a smaller distance from the VFA Komiža, a quicker intervention is possible from the VFA Vis (locations 4, 5 and 14, and vice versa (locations 21, 22 and 25. With the use of a New Service Area, tool intervention times regarding different areas were calculated. Intervention times were divided into intervals: 25 min. The last two categories of area are beyond reach for firefighters within the Standard time of intervention (15 min and together they comprise to 27.88% of the total research area. Conclusions: The results of Closest Facility tool indicate that for the simulated fire position the best/fastest route is not always the shortest one, because of a significant effect of the structural elements of each road, the state of the road and the longitudinal slope of the road

    Despite a reduction in Federal regulatory activity, research concerned with flame retardancy and smoke suppression in the private sector appears to be increasing. This trend seem related to the increased utilization of plastics for end uses which traditionally have employed metal or wood products. As a result, new markets have appeared for thermally stable and fire resistance thermoplastic materials, and this in turn has spurred research and development activity. In addition, public awareness of the dangers associated with fire has increased as a result of several highly publicized hotel and restaurant fires within the past two years. The consumers recognition of flammability characteristics as important materials property considerations has increased. The current status of fire and smoke retardant chemistry and research are summarized.

  6. Methods for Prediction of Steel Temperature Curve in the Whole Process of a Localized Fire in Large Spaces

    Directory of Open Access Journals (Sweden)

    Zhang Guowei

    2014-01-01

    Full Text Available Based on a full-scale bookcase fire experiment, a fire development model is proposed for the whole process of localized fires in large-space buildings. We found that for localized fires in large-space buildings full of wooden combustible materials the fire growing phases can be simplified into a t2 fire with a 0.0346 kW/s2 fire growth coefficient. FDS technology is applied to study the smoke temperature curve for a 2 MW to 25 MW fire occurring within a large space with a height of 6 m to 12 m and a building area of 1 500 m2 to 10 000 m2 based on the proposed fire development model. Through the analysis of smoke temperature in various fire scenarios, a new approach is proposed to predict the smoke temperature curve. Meanwhile, a modified model of steel temperature development in localized fire is built. In the modified model, the localized fire source is treated as a point fire source to evaluate the flame net heat flux to steel. The steel temperature curve in the whole process of a localized fire could be accurately predicted by the above findings. These conclusions obtained in this paper could provide valuable reference to fire simulation, hazard assessment, and fire protection design.

    1979-01-01

    Ignition and combustion studies have provided valuable data and guidelines for sodium fire suppression research. The primary necessity is to isolate the oxidant from the fuel, rather than to attempt to cool the sodium below its ignition temperature. Work along these lines has led to the development of smothering tank systems and a dry extinguishing powder. Based on the results obtained, the implementation of these techniques is discussed with regard to sodium fire suppression in the Super-Phenix reactor. (author)

  9. Angora Fire, Lake Tahoe

    Science.gov (United States)

    2007-01-01

    On the weekend of June 23, 2007, a wildfire broke out south of Lake Tahoe, which stretches across the California-Nevada border. By June 28, the Angora Fire had burned more than 200 homes and forced some 2,000 residents to evacuate, according to The Seattle Times and the Central Valley Business Times. On June 27, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite captured this image of the burn scar left by the Angora fire. The burn scar is dark gray, or charcoal. Water bodies, including the southern tip of Lake Tahoe and Fallen Leaf Lake, are pale silvery blue, the silver color a result of sunlight reflecting off the surface of the water. Vegetation ranges in color from dark to bright green. Streets are light gray, and the customary pattern of meandering residential streets and cul-de-sacs appears throughout the image, including the area that burned. The burn scar shows where the fire obliterated some of the residential areas just east of Fallen Leaf Lake. According to news reports, the U.S. Forest Service had expressed optimism about containing the fire within a week of the outbreak, but a few days after the fire started, it jumped a defense, forcing the evacuation of hundreds more residents. Strong winds that had been forecast for June 27, however, did not materialize, allowing firefighters to regain ground in controlling the blaze. On June 27, authorities hoped that the fire would be completely contained by July 3. According to estimates provided in the daily report from the National Interagency Fire Center, the fire had burned 3,100 acres (about 12.5 square kilometers) and was about 55 percent contained as of June 28. Some mandatory evacuations remained in effect. NASA image by Jesse Allen, using data provided courtesy of the NASA/GSFC/MITI/ERSDAC/JAROS, and U.S./Japan ASTER Science Team.

  14. Fire protection and fire fighting in nuclear installations

    International Nuclear Information System (INIS)

    1989-01-01

    Fires are a threat to all technical installations. While fire protection has long been a well established conventional discipline, its application to nuclear facilities requires special considerations. Nevertheless, for a long time fire engineering has been somewhat neglected in the design and operation of nuclear installations. In the nuclear industry, the Browns Ferry fire in 1975 brought about an essential change in the attention paid to fire problems. Designers and plant operators, as well as insurance companies and regulators, increased their efforts to develop concepts and methods for reducing fire risks, not only to protect the capital investment in nuclear plants but also to consider the potential secondary effects which could lead to nuclear accidents. Although the number of fires in nuclear installations is still relatively large, their overall importance to the safety of nuclear power plants was not considered to be very high. Only more recently have probabilistic analyses changed this picture. The results may well have to be taken into account more carefully. Various aspects of fire fighting and fire protection were discussed during the Symposium, the first of its kind to be organized by the IAEA. It was convened in co-operation with several organizations working in the nuclear or fire protection fields. The intention was to gather experts from nuclear engineering areas and the conventional fire protection field at one meeting with a view to enhancing the exchange of information and experience and to presenting current knowledge on the various disciplines involved. The presentations at the meeting were subdivided into eight sessions: standards and licensing (6 papers); national fire safety practices (7 papers); fire safety by design (11 papers); fire fighting (2 papers); computer fire modeling (7 papers); fire safety in fuel center facilities (7 papers); fire testing of materials (3 papers); fire risk assessment (5 papers).

  15. Fire propagation equation for the explicit identification of fire scenarios in a fire PSA

    International Nuclear Information System (INIS)

    Lim, Ho Gon; Han, Sang Hoon; Moon, Joo Hyun

    2011-01-01

    When performing fire PSA in a nuclear power plant, an event mapping method, using an internal event PSA model, is widely used to reduce the resources used by fire PSA model development. Feasible initiating events and component failure events due to fire are identified to transform the fault tree (FT) for an internal event PSA into one for a fire PSA using the event mapping method. A surrogate event or damage term method is used to condition the FT of the internal PSA. The surrogate event or the damage term plays the role of flagging whether the system/component in a fire compartment is damaged or not, depending on the fire being initiated from a specified compartment. These methods usually require explicit states of all compartments to be modeled in a fire area. Fire event scenarios, when using explicit identification, such as surrogate or damage terms, have two problems: there is no consideration of multiple fire propagation beyond a single propagation to an adjacent compartment, and there is no consideration of simultaneous fire propagations in which an initiating fire event is propagated to multiple paths simultaneously. The present paper suggests a fire propagation equation to identify all possible fire event scenarios for an explicitly treated fire event scenario in the fire PSA. Also, a method for separating fire events was developed to make all fire events a set of mutually exclusive events, which can facilitate arithmetic summation in fire risk quantification. A simple example is given to confirm the applicability of the present method for a 2x3 rectangular fire area. Also, a feasible asymptotic approach is discussed to reduce the computational burden for fire risk quantification

  16. A Systems Perspective on Volunteered Geographic Information

    Directory of Open Access Journals (Sweden)

    Victoria Fast

    2014-12-01

    Full Text Available Volunteered geographic information (VGI is geographic information collected by way of crowdsourcing. However, the distinction between VGI as an information product and the processes that create VGI is blurred. Clearly, the environment that influences the creation of VGI is different than the information product itself, yet most literature treats them as one and the same. Thus, this research is motivated by the need to formalize and standardize the systems that support the creation of VGI. To this end, we propose a conceptual framework for VGI systems, the main components of which—project, participants, and technical infrastructure—form an environment conducive to the creation of VGI. Drawing on examples from OpenStreetMap, Ushahidi, and RinkWatch, we illustrate the pragmatic relevance of these components. Applying a system perspective to VGI allows us to better understand the components and functionality needed to effectively create VGI.

    Lysergic acid diethylamide (LSD) has a history of use as a psychotherapeutic aid in the treatment of mood disorders and addiction, and it was also explored as an enhancer of mind control. The present study sought to test the effect of LSD on suggestibility in a modern research study. Ten healthy volunteers were administered with intravenous (i.v.) LSD (40-80 μg) in a within-subject placebo-controlled design. Suggestibility and cued mental imagery were assessed using the Creative Imagination Scale (CIS) and a mental imagery test (MIT). CIS and MIT items were split into two versions (A and B), balanced for 'efficacy' (i.e. A ≈ B) and counterbalanced across conditions (i.e. 50 % completed version 'A' under LSD). The MIT and CIS were issued 110 and 140 min, respectively, post-infusion, corresponding with the peak drug effects. Volunteers gave significantly higher ratings for the CIS (p = 0.018), but not the MIT (p = 0.11), after LSD than placebo. The magnitude of suggestibility enhancement under LSD was positively correlated with trait conscientiousness measured at baseline (p = 0.0005). These results imply that the influence of suggestion is enhanced by LSD. Enhanced suggestibility under LSD may have implications for its use as an adjunct to psychotherapy, where suggestibility plays a major role. That cued imagery was unaffected by LSD implies that suggestions must be of a sufficient duration and level of detail to be enhanced by the drug. The results also imply that individuals with high trait conscientiousness are especially sensitive to the suggestibility-enhancing effects of LSD.

    2013-01-01

    Recent advances in computer fluid dynamics (CFD) and rapid increase of computational power of current computers have led to the development of CFD models capable to describe fire in complex geometries incorporating a wide variety of physical phenomena related to fire. In this paper, we demonstrate the use of Fire Dynamics Simulator (FDS) for cinema fire modelling. FDS is an advanced CFD system intended for simulation of the fire and smoke spread and prediction of thermal flows, toxic substances concentrations and other relevant parameters of fire. The course of fire in a cinema hall is described focusing on related safety risks. Fire properties of flammable materials used in the simulation were determined by laboratory measurements and validated by fire tests and computer simulations
