    Wells, D P; Yoon, W Y; Harmon, F

    2001-01-01

    The development of 'cabinet-safe' accelerator technology for approx 1-8 MeV electron LINACs would remove the only major barrier to large-scale 'field' applications of these accelerators. These applications range from non-destructive evaluation and assay to radiolytic degradation of hazardous waste. All field applications require large forward dose and very little lateral dose. We investigated the origin, energy, and angular distribution of unwanted lateral radiation dose from two different electron LINACS at three energies. We report on the contributions of various beam parameters to unwanted radiation dose and propose methods to control key beam parameters that significantly contribute to these doses.

  3. A closed cabinet system with water flushers and a blender for breeding small animal administered 3HHO

    International Nuclear Information System (INIS)

    A closed cabinet system was developed for breeding small animals administered 3HHO. 3HHO vapor released from the animals in the chamber was absorbed with water in a water bubbler. Feces and urine which were washed out with water were ground in a blender, diluted, and then released. With this cabinet system we were successful in safely breeding mice even given a total single injection of 15.5 GBq (420 mCi) of 3HHO without storing the 3H-slops for a long time and without any significant leakage of 3H from the cabinet.

    Highlights: > We build the methodology for I and C system upgrade in nuclear power plants. > We describe the interface requirements reflecting a phase upgrade. > Interface requirements we suggest are system configuration, signal interface, and cabinet configuration. - Abstract: This paper presents a standpoint of signal interface for a phased upgrade of instrumentation and control (I and C) systems in a pressurized water reactor (PWR) type nuclear power plant (NPP) in Korea. YongGwang nuclear (YGN) power plant units 3 and 4, which was constructed as a basis model for an optimized power reactor 1000 (OPR1000), is selected as a demonstration model for the presentation. A methodology for building interface requirements is suggested for a phased I and C systems upgrade, maintaining the same functions as those of existing systems, improving functions without violating the compliance requirements, and establishing a safe and economical upgrade schedule. For this, signal interfaces, from the standpoint of safety systems, between I and C cabinets in auxiliary electrical equipment rooms (EER) A and B and the main control room (MCR), the signal interface between the cabinet and the main control board (MCB), and the signal interface between the cabinet and the remote shutdown panel (RSP) are described. This paper focuses on the description of the following interface requirements, reflecting the phased upgrade strategies: system configuration, signal interface, and cabinet configuration. The suggested phased upgrade strategies include the following: non-safety I and C systems should be upgraded in phase 1, safety I and C systems should be upgraded in phase 2, and the MCR should be upgraded in phase 3. The findings presented in the paper can be reliably used to understand upgrade of I and C systems and to implement I and C systems for phased upgrades based on digital technologies.

    2012-07-01

    Security personnel who operate X-ray units for the control of hand luggage and personal items at airports are generally not under dosimetric surveillance. A significant increase in the number of inspected items per passenger, due to rigorous air traffic security measures, raises a question of extended exposure of these workers to scattered X-ray radiation. A new approach to investigating directions of breaches of scattered X-ray radiation in the area near to an X-ray cabinet system, which is based on using active electronic dosemeters is presented. Influence of the increase in the number of inspected items in time on the dose rate is described. Time-dependent dose rates have showed a very good correlation with passengers undergoing security control prior to boarding an airplane. Measurements confirmed that an increase in the dose rate, coinciding with rush hours, was caused by scattered radiation passing through incompletely closed lead curtains. It is found that the doses at the entrance to the inspection tunnel are 50% higher than those at the exit, which is a consequence of inherent operational characteristics of X-ray cabinet systems.

    This project evaluated the air leakage and electric power consumption of Residential HVAC components, with a particular focus on air leakage of furnace cabinets. Laboratory testing of HVAC components indicated that air leakage can be significant and highly variable from unit to unit ? indicating the need for a standard test method and specifying maximum allowable air leakage in California State energy codes. To further this effort, this project provided technical assistance for the development of a national standard for Residential HVAC equipment air leakage. This standard is being developed by ASHRAE and is called"ASHRAE Standard 193P - Method of test for Determining the Air Leakage Rate of HVAC Equipment". The final part of this project evaluated techniques for measurement of furnace blower power consumption. A draft test procedure for power consumption was developed in collaboration with the Canadian General Standards Board: CSA 823"Performance Standard for air handlers in residential space conditioning systems".

    2012-12-18

    Environmental information in physical recovery system of waste refrigerator cabinets was provided in this paper. The system included closed shearing, activated carbon adsorption (ACA), air current separation, magnetic separation, and eddy current separation. Exposures of CFC-11, heavy metals, and noise emitted from the system were assessed. Abundant CFC-11 (>510 mg/m³) was detected in crusher cavity. However, due to the employment of ACA, little CFC-11 (<9.5 mg/m³) could be detected out the recovery system. Heavy metals were detected in the air of workshop (TSP: Cu ≤ 4.91 μg/m³, Pb ≤ 3.17 μg/m³, PM10: Cu ≤ 2.1 μg/m³, Pb ≤ 1.3 μg/m³). Assessment results indicated the concentrations of heavy metals in air were safe for workers. Copper (25.8 mg/kg) and lead (19.5 mg/kg) were found in ground dust of the workshop and the concentrations were safe for soils. Noise level (98.2 dB(A)) of crushing process could cause disease and hearing impairment to workers. For controlling noise, acoustic hood was designed to reduce the noise level to 69.7 dB(A).The above information was of assistance to the industrialization of physical process for recovering waste refrigerator cabinets on environmental protection. Meanwhile, it contributed to the knowledge of environmental information of physical technology for recovering e-waste. PMID:23181933

  13. Human Factors Support in the Design and Evaluation of the Reactor Protection System Cabinet Operator Module

    International Nuclear Information System (INIS)

    A Korean project group, KNICS, is developing a new digitalized reactor protection system (RPS) and the developed system will be packaged into a cabinet with several racks. The cabinet of the RPS is used for the RPS function testing and monitoring by maintenance operators and is equipped with a flat panel display (FPD) with a touch screen capability as a main user interface for the RPS operation. This paper describes the human factors activities involved in the development process of the RPS: conceptual design, design guidance, and evaluation. The activities include a functional requirements analysis and task analysis, user interface style guide for the RPS cabinet operator module (COM), and a human factors evaluation through an experiment and questionnaires

  14. An automated dosimetry system for testing whole-body ultraviolet phototherapy cabinets

    International Nuclear Information System (INIS)

    A new technique is described for automated ultraviolet dosimetry within whole-body phototherapy cabinets. A dual-head detector system has been designed, permitting simultaneous assessment of irradiance levels and radiant intensities from individual lamps. One detector is used in combination with a diffuser/filter system for the measurement of irradiance and the other is mounted at the end of a slit collimator to provide a measurement which can be related to the radiant intensities of the individual lamps. These quantities are derived from 800 separate measurements made during rotation of the detector head around a 360 deg. circle at a fixed height and position within the cabinet under remote computer software control. The device has advantages compared with standard techniques, enabling measurements to be made without the need for a person to be present in the cabinet. A full set of measurements is made with minimal switching of the power supply to the lamps. This simplifies the assessment and reduces the uncertainty from variation in output after the lamps are switched on. Variations in irradiance with orientation for the smaller phototherapy cabinets are clearly demonstrated. Plots of data from the collimated detector show peaks corresponding to the lamps and the surrounding reflectors. The plots enable failed lamps to be detected and peak values can be related to radiant intensities of individual lamps. (author)

    2003-01-01

    Commercial hatcheries typically infuse hydrogen peroxide or formaldehyde gas into hatching cabinets to reduce airborne pathogens that may lead to disease transmission during the hatch. A nonchemical option, an electrostatic space charge system (ESCS), was customized for full-sized commercial hatching cabinets and was tested extensively in broiler hatcheries. The ESCS cleans air by transferring a strong negative electrostatic charge to dust and microorganisms that are aerosolized during the hatch and collecting the charged particles on grounded plates or surfaces. In studies with three poultry companies, the ESCS resulted in significant (P or = 0.05) from those with formaldehyde, and in 93%-96% lower Enterobacteriaceae than with no treatment or with hydrogen peroxide treatment (P hatchery.

  16. Development of a user interface style guide for the reactor protection system cabinet operator module

    International Nuclear Information System (INIS)

    The reactor protection system (RPS) plays the roles of generating the reactor trip signal and the engineered safety features (ESF) actuation signal when the monitored plant processes reach the predefined limits. A Korean project group is developing a new digitalized RPS and the Cabinet Operator Module (COM) of the RPS is used for the RPS integrity testing and monitoring by an equipment operator. A flat panel display (FPD) with a touch screen capability is provided as a main user interface for the RPS operation. To support the RPS COM user interface design, actually the FPD screen design, we developed a user interface style guide because the system designer could not properly deal with the many general human factors design guidelines. To develop the user interface style guide, various design guideline gatherings, a walk-though with a video recorder, guideline selection with respect to user interface design elements, determination of the properties of the design elements, discussion with system designers, and a conversion of the properties into the screen design were carried out. This paper describes the process details and the findings in the course of the style guide development. (Author)

  1. Implications of inherent safe nuclear power system

    International Nuclear Information System (INIS)

    The safety of present day nuclear power reactors and research reactors depends on a combination of design features of passive and active systems, and the alert judgement of their operators. A few inherently safe designs of nuclear reactors for power plants are currently under development. In these designs, the passive systems are emphasized, and the active systems are minimized. Also efforts are made to eliminate the potential for human failures that initiate the series of accidents. If a major system fails in these designs, the core is flooded automatically with coolants that flow by gravity, not by mechanical pumps or electromagnetic actuators. Depending on the choice of the coolants--water, liquid metal and helium gas--there are three principal types of inherently safe reactors. In this paper, these inherently safe reactor designs are reviewed and their implications are discussed. Further, future perspectives of their acceptance by nuclear industries are discussed. (author)

  3. Preliminary Seismic Response and Fragility Analysis for DACS Cabinet

    International Nuclear Information System (INIS)

    A DACS cabinet is installed in the main control room. The objective of this paper is to perform seismic analyses and evaluate the preliminary structural integrity and seismic capacity of the DACS cabinet. For this purpose, a 3-D finite element model of the DACS cabinet was developed and its modal analyses are carried out to analyze the dynamic characteristics. The response spectrum analyses and the related safety evaluation are then performed for the DACS cabinet subject to seismic loads. Finally, the seismic margin and seismic fragility of the DACS cabinet are investigated. A seismic analysis and preliminary structural integrity of the DACS cabinet under self weight and SSE load have been evaluated. For this purpose, 3-D finite element models of the DACS cabinet were developed. A modal analysis, response spectrum analysis, and seismic fragility analysis were then performed. From the structural analysis results, the DACS cabinet is below the structural design limit of under SSE 0.3g, and can structurally withstand until less than SSE 3g based on an evaluation of the maximum effective stresses. The HCLPF capacity for the DGRS of the SSE 0.3g is 0.55g. A modal analysis, response spectrum analysis, and seismic fragility analysis were then performed. From the structural analysis results, the DACS cabinet is below the structural design limit of under SSE 0.3g, and can structurally withstand until less than SSE 3g based on an evaluation of the maximum effective stresses. The HCLPF capacity for the DGRS of the SSE 0.3g is 0.55g. Therefore, it is concluded that the DACS cabinet was safely designed in that no damage to the preliminary structural integrity and sufficient seismic margin is expected

    Venom delivery systems (VDS) are common in the animal kingdom, but rare amongst mammals. New definitions of venom allow us to reconsider its diversity amongst mammals by reviewing the VDS of Chiroptera, Eulipotyphla, Monotremata, and Primates. All orders use modified anterior dentition as the venom delivery apparatus, except Monotremata, which possesses a crural system. The venom gland in most taxa is a modified submaxillary salivary gland. In Primates, the saliva is activated when combined with brachial gland exudate. In Monotremata, the crural spur contains the venom duct. Venom functions include feeding, intraspecific competition, anti-predator defense and parasite defense. Including mammals in discussion of venom evolution could prove vital in our understanding protein functioning in mammals and provide a new avenue for biomedical and therapeutic applications and drug discovery.

    Generally, the present disclosure is directed to gas monitoring systems that use inductive power transfer to safely power an electrically passive device included within a nuclear material storage container. In particular, the electrically passive device can include an inductive power receiver for receiving inductive power transfer through a wall of the nuclear material storage container. The power received by the inductive power receiver can be used to power one or more sensors included in the device. Thus, the device is not required to include active power generation components such as, for example, a battery, that increase the risk of a spark igniting flammable gases within the container.

  9. Project SAFE. Scenario and system analysis

    International Nuclear Information System (INIS)

    This report describes the scenario analysis conducted within the SAFE project, which has resulted in a qualitative description of the SFR disposal system. The scenario report generally documents and justifies the selected system description model, selected scenario initiating events and conditions, the general selection of the type of quantitative evaluation models to be used and the information flow between models. The development of a system description model is done by groups of experts through a series of documented meetings, utilising the Interaction Matrix methodology. This methodology involves a systematic identification of processes and interactions between these processes occurring in the system and documented expert judgements of the relevance of these processes and interactions for the evolution of the system. The SFR disposal system is described by three coupled matrices: one for the repository vaults, one for the geosphere and one for the biosphere. The contents of the matrices have been audited against different international lists of FEPs (Features, Events, Processes) in order to ensure that all FEPs that are relevant are considered in the matrices. These lists of FEPs as well as experiences from past and recent SKB assessments have also been used in the selection of scenario initiating events and conditions. The system description in terms of interaction matrices cannot directly be used in the quantitative assessment. However, the system description can be used to point out the important interactions and how they should be treated in the quantitative analyses and to check that this is done. For this purpose an information flow diagram has been used. This diagram graphically displays the information exchange between the different analyses selected for the quantitative assessment of the evolution of the disposal system

  13. Variation of Modal Characteristics of Electrical Cabinet According to the Excitation Level in Impact Hammer Test

    International Nuclear Information System (INIS)

    There are many electrical cabinets in nuclear power plants. Safety-related equipment is typically seismic qualified before installation. Seismic qualification of equipment is possible when identifying the accurate dynamic characteristics of the equipment. According to the nature of the cabinet, the dynamic characteristics of the electrical cabinet vary nonlinearly with excitation level. This study analyzed the nonlinear variation of the dynamic properties of an actual cabinet. For the purpose of this study, a seismic monitoring system cabinet was selected as a specimen. The impact hammer tests were conducted to identify a variation of the dynamic characteristics of the specimen by increasing the impulse level. Modal identification technique was used to extract the modal properties of the cabinet from the measurements

    The Model Authoring System is a prototype software application for generating fault tree analyses and failure mode and effects analyses for circuit designs. Utilizing established artificial intelligence and expert system techniques, the circuits are modeled as a frame-based knowledge base in an expert system shell, which allows the use of object oriented programming and an inference engine. The behavior of the circuit is then captured through IF-THEN rules, which then are searched to generate either a graphical fault tree analysis or failure modes and effects analysis. Sophisticated authoring techniques allow the circuit to be easily modeled, permit its behavior to be quickly defined, and provide abstraction features to deal with complexity.

Characteristics of fission and NTP indicate that useful first generation systems will provide a foundation for future systems with extremely high performance. The role of the NCPS in the development of advanced nuclear propulsion systems could be analogous to the role of the DC-3 in the development of advanced aviation. Progress made under the NCPS project could help enable both advanced NTP and advanced Nuclear Electric Propulsion (NEP).

    Fail-safe systems and design methodologies for large capacity battery systems are disclosed. The disclosed systems and methodologies serve to locate a faulty cell in a large capacity battery, such as a cell having an internal short circuit, determine whether the fault is evolving, and electrically isolate the faulty cell from the rest of the battery, preventing further electrical energy from feeding into the fault.

  18. Fail-safe computer-based plant protection systems

    International Nuclear Information System (INIS)

    A fail-safe mode of operation for computers used in nuclear reactor protection systems was first evolved in the UK for application to a sodium cooled fast reactor. The fail-safe properties of both the hardware and the software were achieved by permanently connecting test signals to some of the multiplexed inputs. This results in an unambiguous data pattern, each time the inputs are sequentially scanned by the multiplexer. The ''test inputs'' simulate transient excursions beyond defined safe limits. The alternating response of the trip algorithms to the ''out-of-limits'' test signals and the normal plant measurements is recognised by hardwired pattern recognition logic external to the computer system. For more general application to plant protection systems, a ''Test Signal Generator'' (TSG) is used to compute and generate test signals derived from prevailing operational conditions. The TSG, from its knowledge of the sensitivity of the trip algorithm to each of the input variables, generates a ''test disturbance'' which is superimposed upon each variable in turn, to simulate a transient excursion beyond the safe limits. The ''tripped'' status yielded by the trip algorithm when using data from a ''disturbed'' input forms part of a pattern determined by the order in which the disturbances are applied to the multiplexer inputs. The data pattern formed by the interleaved test disturbances is again recognised by logic external to the protection system's computers. This fail-safe mode of operation of computer-based protection systems provides a powerful defence against common-mode failure. It also reduces the importance of software verification in the licensing procedure. (author)

    The mechanical-physical process was proven to be technologically feasible for waste refrigerator recycling and has been widely used in the typical e-waste recycling factories in China. In this study, effects of the acoustic hood on the reduction of noise level, CFC-11, and heavy metals (Cr, Ni, Cu, Cd, and Pb) in particulate matter (PM) were evaluated. For noise pollution, the noise level inside and outside the acoustic hood was 96.4 and 78.9 dB, respectively. Meanwhile, it had a significant effect on A-weighted sound level with a reduction from 98.3 to 63.6 dB. For CFC-11 exposure, abundant CFC-11 (255 mg/m(3)) was detected in the acoustic hood. However, the mean concentration of CFC-11 at the outline of polyurethane foam collection was obviously diminished to 14 mg/m(3), and no CFC-11 was monitored around the acoustic hood. The concentrations of PM and heavy metals in PM outside the acoustic hood were lower than those inside the acoustic hood due to the physical barriers of the acoustic hood. Based on the risk assessment, only adverse health effect caused by Pb might likely appear. All the results can provide the basic data for pollution control and risk assessment in waste refrigerator recycling system. PMID:24965005

  5. A fail-safe computer-based reactor protection system

    International Nuclear Information System (INIS)

    It is possible to bestow fail-safe properties upon any data handling system by specifying that the output shall be dynamic (i.e. shall cyclically alternate between two or more static states) and that all internal states shall also be dynamic. The choice of cyclic sequence of static states must ensure that every part of the system (each bit) is regularly exercised at a rate determined by the maximum MTTR (mean time to repair) of the system which in turn must be short compared with the MTBF (mean time between failures). Although the examples given are of very simple computer tasks which basically replace conventional trip unit and safety circuit logic hardware, the principles could be extrapolated to more complex data processing tasks.

  6. System design for safe robotic handling of nuclear materials

    International Nuclear Information System (INIS)

    Robotic systems are being developed by the Intelligent Systems and Robotics Center at Sandia National Laboratories to perform automated handling tasks with radioactive nuclear materials. These systems will reduce the occupational radiation exposure to workers by automating operations which are currently performed manually. Because the robotic systems will handle material that is both hazardous and valuable, the safety of the operations is of utmost importance; assurance must be given that personnel will not be harmed and that the materials and environment will be protected. These safety requirements are met by designing safety features into the system using a layered approach. Several levels of mechanical, electrical and software safety prevent unsafe conditions from generating a hazard, and bring the system to a safe state should an unexpected situation arise. The system safety features include the use of industrial robot standards, commercial robot systems, commercial and custom tooling, mechanical safety interlocks, advanced sensor systems, control and configuration checks, and redundant control schemes. The effectiveness of the safety features in satisfying the safety requirements is verified using a Failure Modes and Effects Analysis. This technique can point out areas of weakness in the safety design as well as areas where unnecessary redundancy may reduce the system reliability

    This study investigated the specific fluid dynamics characteristics of cytotoxic safety cabinets (CSC), particularly those used in cancer drug reconstitution operations. Measurements taken on site were used to derive characteristic data for these cabinets. An in-depth laboratory investigation of airflows inside another CSC was also conducted. Anemometric values recorded on these two installations enabled the experimental validation of computational fluid dynamics methods applied to CSC. The digital flow simulations conducted provide a better understanding of the detailed flow structure inside a CSC and made it possible to study the influence of different operating parameters on the air velocity distribution inside the cabinet front opening: recycled air temperature, product protection airflow rate, suction openings spatial distribution, air compensation mode and draughts, operator arm penetration, and operator presence in front of the cabinet.

    Standoff Raman imaging systems have shown the ability to detect single explosives particles. However, in many cases, the laser intensities needed restrict the applications where they can be safely used. A new generation imaging Raman system has been developed based on a 355 nm UV laser that, in addition to eye safety, allows discrete and invisible measurements. Non-dangerous exposure levels for the eye are several orders of magnitude higher in UVA than in the visible range that previously has been used. The UV Raman system has been built based on an UV Fabry-Perot Interferometer (UV-FPI) developed by VTT. The design allows for precise selection of Raman shifts in combination with high out-of-band blocking. The stable operation of the UV-FPI module under varying environmental conditions is arranged by controlling the temperature of the module and using a closed loop control of the FPI air gap based on capacitive measurement. The system presented consists of a 3rd harmonics Nd:YAG laser with 1.5 W average output at 1000 Hz, a 200 mm Schmidt-Cassegrain telescope, UV-FPI filter and an ICCD camera for signal gating and detection. The design principal leads to a Raman spectrum in each image pixel. The system is designed for field use and easy manoeuvring. Preliminary results show that in measurements of <60 s on 10 m distance, single AN particles of <300 μm diameter can be identified.

    2001-10-31

    In this two year program Universal Display Corporation (UDC) together with the University of Michigan, Teknokon, developed and delivered an energy efficient phosphorescent OLED under cabinet illumination system. Specifically the UDC team goal was in 2011 to deliver five (5) Beta level OLED under cabinet lighting fixtures each consisting of five 6-inch x 6-inch OLED lighting panels, delivering over 420 lumens, at an overall system efficacy of >60 lm/W, a CRI of >85, and a projected lifetime to 70% of initial luminance to exceed 20,000 hours. During the course of this program, the Team pursued the commercialization of these OLED based under cabinet lighting fixtures, to enable the launch of commercial OLED lighting products. The UDC team was ideally suited to develop these novel and efficient solid state lighting fixtures, having both the technical experience and commercial distribution mechanisms to leverage work performed under this contract. UDC's business strategy is to non-exclusively license its PHOLED technology to lighting manufacturers, and also supply them with our proprietary PHOLED materials. UDC is currently working with several licensees who are manufacturing OLED lighting panels using our technology. During this 2 year program, we further developed our high efficiency white Phosphorescent OLEDs from the first milestone, achieving a 80 lm/W single pixel to the final milestone, achieving an under-cabinet PHOLED lighting system that operates at 56 lm/W at 420 lumens. Each luminaire was comprised of ten 15cm x 7.5cm lighting modules mounted in outcoupling enhancement lenses and a control module. The lamps modules are connected together using either plugs or wires with plugs on each end, allowing for unlimited configurations. The lamps are driven by an OLED driver mounted in an enclosure which includes the AC plug. As a result of advancements gained under this program, the path to move OLED lighting panels from development into manufacturing has been

    2015-01-01

    Spray drift is one of the main sources of pesticide contamination. For this reason, an accurate understanding of this phenomenon is necessary in order to limit its effects. Nowadays, spray drift is usually studied by using in situ collectors which only allow time-integrated sampling of specific points of the pesticide clouds. Previous research has demonstrated that the light detection and ranging (lidar) technique can be an alternative for spray drift monitoring. This technique enables remote measurement of pesticide clouds with high temporal and distance resolution. Despite these advantages, the fact that no lidar instrument suitable for such an application is presently available has appreciably limited its practical use. This work presents the first eye-safe lidar system specifically designed for the monitoring of pesticide clouds. Parameter design of this system is carried out via signal-to-noise ratio simulations. The instrument is based on a 3-mJ pulse-energy erbium-doped glass laser, an 80-mm diameter telescope, an APD optoelectronic receiver and optomechanically adjustable components. In first test measurements, the lidar system has been able to measure a topographic target located over 2 km away. The instrument has also been used in spray drift studies, demonstrating its capability to monitor the temporal and distance evolution of several pesticide clouds emitted by air-assisted sprayers at distances between 50 and 100 m.

    Since long time passive systems have been adopted in architecture due to their importance for energy saving, utilisation of environmentally friendly component, low costs. The applications of passive techniques to building depend on the availability of design tools and methods for the characterisation of the performance of components. Therefore, in order to develop simplified design tool and increase confidence in numerical simulation through experimental validation, the aim of the paper is to study a passive system able to work in emergency conditions without any conventional energy source, minimising their environmental impact without any decrease of reliability, modularity and economy. The paper deals with the preliminary study of the natural convection in a water heat exchanger during the transient phase of start up. The feasibility study is focused on a simple heat transfer loop based on a single closed vertical circuit, heated in the lower section and cooled in the upper one, on the base of the first important experimental results pointed out in recent years (Department of Fisica Teorica of Genua University). The introduction of simplified design correlations will also lead to simplified calculation guidelines for thermosyphon installations. The evaluation of unsteady behaviour has been carried out characterising a pulsed thermal source at variable frequencies and different heat flow rates, and for the evaluation of the transient duration and the study of instability, fluid velocity and temperature profiles for different circuit sections have been analysed. A simulation of thermal-circulation with a pulsed natural convection has been carried out by means of a numerical CFD code. The comparison of the numerical simulation results with the equations governing the physical phenomena involved may lead to definition of a design correlation for an innovative and inherently safe emergency cooling system able to remove intensive thermal loads rising in a space during

    Full Text Available Objectives: The aim of the present study was to investigate immunotoxic effect of safranal (SAF, a main component of Crocus sativus essential oil, using Balb/c mice. Materials and Methods: SAF was administered intraperitoneally at doses of 0.1, 0.5 and 1 ml/kg for 3 weeks. Hystopathological examination of spleen and bone marrow, cellularity of spleen, delayed type of hypersensitivity (DTH response, hemagglutination titer (HA, cytokine production and lymphocyte proliferation assay were studied in various groups of animals. Results: Spleen cellularity for SAF groups (0.1 ml/kg SAF: 6.68 [± 0.88] × 107, 0.5 ml/kg SAF: 8.16 [± 1.33] × 107, 1 ml/kg SAF: 6.12 [± 0.59] × 107 did not significantly differ as compared to vehicle control (8.52 [± 1.36] × 107; p > 0.05. In addition, SAF at all doses could not produce any significant changes in hematological parameters, HA titer, DTH and lymphoproliferation responses, as well as in release of cytokines by isolated splenocytes (p > 0.05. Despite a few studies demonstrating some immunomodulatory effects for saffron extract, SAF as a major constituent of saffron did not induce any marked effects in immune system parameters of mice. Conclusion: Contrary to the toxicological studies which have indicated that SAF is more toxic than other active constituents in saffron stigma, at least it was found to be safe to mice immune system and has no toxicity on humoral and cellular immune responses.

    The Beam Interlock System (BIS) and Safe Machine Parameters (SMP) system are central to the protection of the Large Hadron Collider (LHC) machine. The BIS has been critical for the safe operation of LHC from the first day of operation. It has been installed and commissioned, only minor enhancements are required in order to accommodate all future LHC machine protection requirements. At reduced intensity, the SMP system is less critical for LHC operation. As such, the current system satisfies the 2010 operational requirements. Further developments are required, both at the SMP Controller level, and at the system level, in order to accommodate the requirements of the LHC beyond 2010.

  18. An experimental investigation of internally ignited fires in nuclear power plant control cabinets: Part 1: Cabinet effects tests

    International Nuclear Information System (INIS)

    A series of full-scale cabinet fire tests was conducted by Sandia National Laboratories for the US Nuclear Regulatory Commission. The cabinet fire tests were prompted by the potential threat to the safety of a nuclear power plant by a cabinet fire in either the control room or in a switchgear type room. The purpose of these cabinet fire tests was to characterize the development and effects of internally ignited cabinet fires as a function of several parameters believed to most influence the burning process. A primary goal of this test program was to test representative and credible configurations and materials. This series of 22 cabinet fire tests demonstrated that fires in either benchboard or vertical cabinets with either IEEE-383 qualified cable or unqualified cable can be ignited and propagate. However, fires with IEEE-383 qualified cable do not propagate as rapidly nor to the extent that unqualified cable does. Furthermore, the results showed that the thermal environment in the test enclosure and adjacent cabinets is not severe enough to result in autoignition of other combustibles; although in some of the larger fires melting of plastic materials may occur. Smoke accumulation in the room appeared to be the most significant problem, as smoke obscured the view in the enclosure within minutes after ignition. Essentially, a cabinet fire can propagate within a single cabinet; however, for the conditions tested it does not appear that the fire poses a threat outside the burning cabinet except the resulting smoke

    For class II, type A2 biological safety cabinets (BSC), NSF/ANSI Standard 49 should be conformed in cabinet airflow velocity derivation, particle contamination, and aerodynamic flow properties. However, there exists a potential problem. It has been built that the cabinet air flow stabilize is influenced by the quantity of downflow of air and the height above the cabinet exhaust opening. Three air downflow quantities were compared as an operating apparatus was placed from 20 to 40 cm above the bench of the cabinet. The results show that the BSC air downflow velocity is a function of increased sampling height, displaying that containment is improvingly permitted over product protection as the sampling height decreases. This study investigated the concentration gradient of particles at various heights and downflow air quantity from the bench of the BSC. Experiment results indicate that performance near the bench was better than in the rest of the BSC. In terms of height, the best cleanliness was measured at a height of 10 cm over the bench; it reduced actually with add in height. The empirical curves accommodate, founded on the concentration gradient of particle created was elaborated for evaluating the particle concentration at different heights and downflow air quantity from the source of the bench of the BSC. The particle image velocimetry system applied for BSC airflow research to fix amount of airflow patterns and air distribution measurement and results of measurements show how obstructions can greatly influence the airflow and contaminant transportation in a BSC.

  4. The concept of passive cooling systems for inherently safe BWRs

    International Nuclear Information System (INIS)

    The Fukushima Daiichi Nuclear Power Plant accident and its consequences have led to extensive rethinking about the safety technologies used in boiling water reactors (BWRs). As one of the options of the safety technologies, we have been developing passive cooling systems consisting of a water-cooling system and an infinite-time air-cooling system. These systems achieve core cooling without electricity and are intended to cope with a long-term station blackout (SBO). Both these cooling systems remove relatively high decay heat for the initial 10 days after an accident, and then the infinite-time air-cooling system continues to remove attenuated decay heat after this period. To obtain heat transfer data for the design of the water-cooling system, we conducted heat transfer tests using a full-scale U-shaped single tube. The data were obtained at a system pressure of 0.2 to 3.0 MPa (absolute) and inlet steam velocity of 5 to 56 m/s. To enhance heat transfer of the air-cooling system, we successfully implemented some air-cooling enhancing technologies. The performance was evaluated by heat transfer data obtained from the element heat transfer tests. The heat transfer performance increased at least 100% with the enhancement technologies compared with a bare tube. From these test results, we confirmed good feasibility for application of the cooling systems. (author)

  9. Determining safe shutdown systems and seismic upgrade priorities

    International Nuclear Information System (INIS)

    This paper describes how lessons learned from US and Western Europe safety improvement programs as well as insights in WWER systems can be used to perform top level seismic safety assessments and narrow the scope of WWER seismic upgrading while still satisfying enhanced safety goals. A clear definition and understanding of the systems requirements and interactions with other possible upgrades is a prerequisite to a practical and effective seismic upgrade program. (author)

  10. In-cabinet response spectra development for nuclear power plant motor control centers

    International Nuclear Information System (INIS)

    Electrical Components within older nuclear power plant Motor Control Centers (MCC) are becoming obsolete and may require replacement. Many of these components are safety-related and are required to remain functional during and after a Safe Shutdown Earthquake (SSE). New component seismic qualification is typically demonstrated per IEEE 344 by shake table testing the components. To validate the shake table test data, the Test Response Spectra (TRS) must be shown to envelope the Required Response Spectra (RRS) of the component. Due to the panel's flexibility, the panel will amplify the floor response spectra. The amplification factor is dependent on the panel geometry, mass magnitude, and location of electrical components inside the panel. A two step approach is presented to develop the in-cabinet response spectra (i.e., RRS) at the individual electrical component's location. The modal properties of the panel are first obtained using finite element and modal analysis techniques. The modal properties, mass of the component, and the base floor response spectra are then used as input to ABB Impell's FLORA program. The FLORA program generates the RRS curves for the composite panel component system using modal synthesis and perturbation techniques taking into account the oscillator/panel coincident frequencies and the interaction between the electrical component and the MCC panel. In one case, this approach yielded a realistic Amplification Factor of 0.84 compared to factors of 3 and higher from more conservative methods

  11. Cyberterrorism: is the U.S. healthcare system safe?

    Science.gov (United States)

    Harries, David; Yellowlees, Peter M

    2013-01-01

    The Internet has brought with it many benefits; key among them has been its ability to allow the expansion of communication and transfer of all kinds of information throughout the U.S. healthcare system. As a consequence, healthcare has become increasingly dependent on the activities carried out in that environment. It is this very dependence that increases the likelihood of individuals or organizations conducting activities through the Internet that will cause physical and/or psychological harm. These activities have become known by the term "cyberterrorism." In the healthcare landscape this can appear in a variety of forms, such as bringing down a hospital computer system or publicly revealing private medical records. Whatever shape it takes, the general effects are the same: patient care is compromised, and trust in the health system is diminished. Fortunately no significant cyber attack has been successfully launched against a U.S. healthcare organization to date. However, there is evidence to suggest that cyber threats are increasing and that much of the U.S. healthcare system is ill equipped to deal with them. Securing cyberspace is not an easy proposition as the threats are constantly changing, and recognizing that cyberterrorism should be part of a broader information technology risk management strategy, there are several"best practices" that can be adopted by healthcare organizations to protect themselves against cyber attacks.

    A comprehensive listing of the generic codimension-1 attractor bifurcations of dissipative dynamical systems is presented. It includes local and global bifurcations of regular and chaotic attractors. The bifurcations are classified according to the continuity or discontinuity of the attractor path, which governs the physical outcome that would be observed under a slow control sweep. Related issues of determinacy, hysteresis, basin structure, and intermittency are addressed. Recently discovered chaotic bifurcations are discussed in some detail, with particular reference to the regular or chaotic saddle-type destroyer with which an attractor may collide.

    Nowadays multimedia projectors of various types are widely used in many areas of human life. Significant part of all projector devices are used in two main areas: education (e. g. on lectures) and business (e. g. on all sorts of meetings). What makes projector a demanded device? It provides a user with high quality full color large diagonal image for a much lower price than display devices that based on other popular non-projecting technologies. However the absolute majority of projectors share a significant disadvantage. If human steps into the beam two major negative effects appear: a distorted image appears on human's body and human's eyes become glared by bright light. The first effect is undesirable by the audience and the second effect is undesirable by the presenter. To avoid the abovementioned effects short throw projectors can be used but they are more expensive than regular ones and have significant limitations on the placement spot: usually the lens of a short-throw projector is designed so that it has to be placed on a fixed distance to the screen. We propose a different solution of similar problem: instead of moving the projector towards the screen let us black out the human (or other obstacle) from it. To do so our system must know the exact position of human. In this paper we propose a system with flexible architecture that realizes the above-mentioned solution.

    Air-insulated switchgear cabinet plays a critical role in entire power transmission and distribution system. Its stability directly affects the operational reliability of the power system. And the on-line gas detection method, which evaluates the insulation status of insulation equipment by detecting the decomposition components of filled air in cabinet, becomes an innovative way to ensure the running stability of air-insulated switchgear cabinet. In order to study the characteristic gas types and production regularity of decomposition components under partial discharge, three insulation defects: needle-plate, air-gap and impurity defect are proposed to simulate the insulation defects under partial discharge in air-insulated switchgear cabinet. Firstly, the generation pathways and mechanism of composition components are discussed. Then CO and NO2 are selected as the characteristic decomposition components to characterize the partial discharge due to their high concentration and chemical stability. Based on the different change regularity of CO and NO2 concentration under different insulation defect, it provides an effective way to evaluate and predict the insulation defect type and severity in the field.

  19. Seismic response prediction for cabinets of nuclear power plants by using impact hammer test

    International Nuclear Information System (INIS)

    An effective method to predict the seismic response of electrical cabinets of nuclear power plants is developed. This method consists of three steps: (1) identification of the earthquake-equivalent force based on the idealized lumped-mass system of the cabinet, (2) identification of the state-space equation (SSE) model of the system using input-output measurements from impact hammer tests, and (3) seismic response prediction by calculating the output of the identified SSE model under the identified earthquake-equivalent force. A three-dimensional plate model of cabinet structures is presented for the numerical verification of the proposed method. Experimental validation of the proposed method is carried out on a three-story frame which represents the structure of a cabinet. The SSE model of the frame is accurately identified by impact hammer tests with high fitness values over 85% of the actual frame characteristics. Shaking table tests are performed using El Centro, Kobe, and Northridge earthquakes as input motions and the acceleration responses are measured. The responses of the model under the three earthquakes are predicted and then compared with the measured responses. The predicted and measured responses agree well with each other with fitness values of 65-75%. The proposed method is more advantageous over other methods that are based on finite element (FE) model updating since it is free from FE modeling errors. It will be especially effective for cabinet structures in nuclear power plants where conducting shaking table tests may not be feasible. Limitations of the proposed method are also discussed.

  20. A dynamic fail-safe approach to the design of computer-based safety systems

    International Nuclear Information System (INIS)

    For over 30 years AEA Technology has carried out research and development in the field of nuclear instrumentation and protection systems. Throughout the course of this extensive period of research and development the dominant theme has been the achievement of fully fail-safe designs. These are defined as designs in which the failure of any single component will result in the unit output reverting to a demand for trip action status. At an early stage it was recognized that the use of dynamic rather than static logic could ease the difficulties inherent in achieving a fail-safe design. The first dynamic logic systems coupled logic elements magnetically. The paper outlines the evolution from these early concepts of a dynamic fail-safe approach to the design of computer-based safety systems. Details are given of collaboration between AEA Technology and Duke Power Co. to mount an ISATTM demonstration at Duke's Oconee Nuclear Power Station

    Gumzej, Roman

    2016-01-01

    This book introduces the concept of holistic design and development of cyber physical systems to achieve their safe and secure operation. It shows that by following the standards for embedded system’s safety and using appropriate hardware and software components inherently safe system’s architectures can be devised and certified. While the standards already enable testing and certification of inherently safe and sound hardware, this is still not the case with software. The book demonstrates that Specification PEARL(SPEARL) addresses this issue and proposes appropriate solutions from the viewpoints of software engineering as well as concrete program components. By doing so it reduces the complexity of cyber physical systems design in an innovative way. Three ultimate goals are being followed in the course of defining this new PEARL standard, namely: 1. simplicity over complexity, 2. inherent real-time ability, and 3. conformity to safety integrity and security capability levels.

    Many surgeons in low-resource settings do not have access to safe, affordable, or reliable surgical drilling tools. Surgeons often resort to nonsterile hardware drills because they are affordable, robust, and efficient, but they are impossible to sterilize using steam. A promising alternative is to use a Drill Cover system (a sterilizable fabric bag plus surgical chuck adapter) so that a nonsterile hardware drill can be used safely for surgical bone drilling. Our objective was to design a safe, effective, affordable Drill Cover system for scale in low-resource settings. We designed our device based on feedback from users at Mulago Hospital (Kampala, Uganda) and focused on 3 main aspects. First, the design included a sealed barrier between the surgical field and hardware drill that withstands pressurized fluid. Second, the selected hardware drill had a maximum speed of 1050 rpm to match common surgical drills and reduce risk of necrosis. Third, the fabric cover was optimized for ease of assembly while maintaining a sterile technique. Furthermore, with the Drill Cover approach, multiple Drill Covers can be provided with a single battery-powered drill in a "kit," so that the drill can be used in back-to-back surgeries without requiring immediate sterilization. The Drill Cover design presented here provides a proof-of-concept for a product that can be commercialized, produced at scale, and used in low-resource settings globally to improve access to safe surgery.

    Verify-and-record (V and R) systems are being used increasingly, not only for verification, but also for computer aided setup and chart printing. The close intercorrelation between V and R system and treatment routine requires new ideas for quality assurance (QA): pure ''machine checking'' as with treatment units is not sufficient anymore. The level of QA obviously depends on the tasks of the V and R system: the most advanced case of the system being used for computer aided setup and for chart printing is discussed -both are indispensable for an efficient use of V and R systems. Seven propositions are defined to make this not only efficient but safe. (author)

    In this paper, a new approach for a multilayer elastic beam to provide a driving force and driving distance for a MEMS safe and arming system is presented. In particular this is applied where a monolayer elastic beam cannot provide adequate driving force and driving distance at the same time in limited space. Compared with thicker elastic beams, the bilayer elastic beam can provide twice the driving force of a monolayer beam to guarantee the MEMS safe and arming systems work reliably without decreasing the driving distance. In this paper, the theoretical analysis, numerical simulation and experimental verification of the multilayer elastic beam is presented. The numerical simulation and experimental results show that the bilayer elastic provides 1.8–2 times the driving force of a monolayer, and a method that improves driving force without reducing the driving distance.

  1. The Challenge of Providing Safe Water with an Intermittently Supplied Piped Water Distribution System

    Science.gov (United States)

    Kumpel, E.; Nelson, K. L.

    2012-12-01

    An increasing number of urban residents in low- and middle-income countries have access to piped water; however, this water is often not available continuously. 84% of reporting utilities in low-income countries provide piped water for fewer than 24 hours per day (van den Berg and Danilenko, 2010), while no major city in India has continuous piped water supply. Intermittent water supply leaves pipes vulnerable to contamination and forces households to store water or rely on alternative unsafe sources, posing a health threat to consumers. In these systems, pipes are empty for long periods of time and experience low or negative pressure even when water is being supplied, leaving them susceptible to intrusion from sewage, soil, or groundwater. Households with a non-continuous supply must collect and store water, presenting more opportunities for recontamination. Upgrading to a continuous water supply, while an obvious solution to these challenges, is currently out of reach for many resource-constrained utilities. Despite its widespread prevalence, there are few data on the mechanisms causing contamination in an intermittent supply and the frequency with which it occurs. Understanding the impact of intermittent operation on water quality can lead to strategies to improve access to safe piped water for the millions of people currently served by these systems. We collected over 100 hours of continuous measurements of pressure and physico-chemical water quality indicators and tested over 1,000 grab samples for indicator bacteria over 14 months throughout the distribution system in Hubli-Dharwad, India. This data set is used to explore and explain the mechanisms influencing water quality when piped water is provided for a few hours every 3-5 days. These data indicate that contamination occurs along the distribution system as water travels from the treatment plant to reservoirs and through intermittently supplied pipes to household storage containers, while real

    2008-11-15

    The City of Amsterdam's Environmental and Building Department commissioned the Energy research Centre of the Netherlands (ECN) to calculate the time needed to recoup the cost of closing the existing refrigerator and freezer display cabinets used in supermarkets. We were asked to give particular consideration to the following aspects: (1) The cabinet's energy consumption; (2) The energy price; and (3) The cost of closing the cabinet. The payback period has been calculated by dividing the investment required to close the cabinet by the amount saved on energy each year, less any additional costs incurred as a result of the scheme. For existing upright refrigerator cabinets, that period works out at 2.9 years with a margin error of {+-}0.9 years. In the case of chest freezers, it is approximately 2.4 years, with a maximum of 2.5 and a minimum of 1.3 years. For chest refrigerators, the payback period is 9.4 years. If units are closed overnight only, the time needed to payback the cost of that measure ranges between 1.8 and 4.1 years. Moreover, research shows that closing refrigerator and freezer display units will not reduce turnover. In addition, it will significantly improve the ambient climate in supermarkets.

The conditions of fractal erosion of the safe basin of the controlled system on the basis that the range of time delay leading to good control is obtained by the Melnikov method. It is found that the increasing time delay can reduce the basin erosion under a weak and positive feedback gain. Then the evolutions of safe basins with time delay are presented in detail by the fourth Runge-Kutta and Monte-Carlo methods, which shows that the safe basin of the controlled Holmes-Duffing system can be expanded, and its fractal can be reduced by the increasing time delay. These results suggest that delayed position feedbacks can be used as a good approach to control the erosion of safe basins.

  4. Characterisation of open-door electrical cabinet fires in compartments

    International Nuclear Information System (INIS)

    Highlights: • Heat release rate of electrical cabinet fire source in a vitiated atmosphere. • Experimental database for proper validation the combustible modelling, taking into account the oxygen depletion in an enclosure. • New model for complex fire source. - Abstract: The study of electrical fires is a major concern for fire safety in the industry and more particularly for fire safety in nuclear facilities. To investigate this topic, IRSN conducted a large number of real-scale experiments involving open-door electrical cabinets burning firstly under a calorimetric hood and then inside a mechanically-ventilated compartment. The main challenges are to determine accurately the heat release rate of such a complex fire source in a vitiated atmosphere and to provide an experimental database for validating properly the combustible modelling, taking into account the oxygen depletion in an enclosure. After providing a detailed description of the fire scenarios and of the experimental apparatus, this paper focuses on the characteristic stages of the cabinet fire development, essentially based on the heat release rate time evolution of the fire. The effects of the confinement, of the outlet branch location, of the ventilation management and of the fire barrier on the fire source were then investigated. The reproducibility of electrical cabinet fires is also studied. A new model for complex fire source (applied in this study for open-door electrical cabinet fires) was then developed. This model was introduced in the zone code SYLVIA and the major features of the compartment fire experiments, such as characteristic heat release rate with effect of oxygen depletion and over-pressure peak were then calculated with a rather good agreement for this complex fire source (i.e. electrical cabinet)

    Full Text Available An ontology-driven safe food consumption mobile system is considered. Over 3,000 compounds are being added to processed food, with numerous effects on the food: to add color, stabilize, texturize, preserve, sweeten, thicken, add flavor, soften, emulsify, and so forth. According to World Health Organization, governments have lately focused on legislation to reduce such ingredients or compounds in manufactured foods as they may have side effects causing health risks such as heart disease, cancer, diabetes, allergens, and obesity. By supervising what and how much to eat as well as what not to eat, we can maximize a patient’s life quality through avoidance of unhealthy ingredients. Smart e-health systems with powerful knowledge bases can provide suggestions of appropriate foods to individuals. Next-generation smart knowledgebase systems will not only include traditional syntactic-based search, which limits the utility of the search results, but will also provide semantics for rich searching. In this paper, performance of concept matching of food ingredients is semantic-based, meaning that it runs its own semantic based rule set to infer meaningful results through the proposed Ontology-Driven Mobile Safe Food Consumption System (FoodWiki.

  6. Inherently Safe and Long-Life Fission Power System for Lunar Outposts

    Schriener, T. M.; El-Genk, Mohamed S.

    Power requirements for future lunar outposts, of 10's to 100's kWe, can be fulfilled using nuclear reactor power systems. In addition to the long life and operation reliability, safety is paramount in all phases, including fabrication and assembly, launch, emplacement below grade on the lunar surface, operation, post-operation decay heat removal and long-term storage and eventual retrieval. This paper introduces the Solid Core-Sectored Compact Reactor (SC-SCoRe) and power system with static components and no single point failures. They ensure reliable continuous operation for ~21 years and fulfill the safety requirements. The SC-SCoRe nominally generates 1.0 MWth at liquid NaK-56 coolant inlet and exit temperatures of 850 K and 900 K and the power system provides 38 kWe at high DC voltage using SiGe thermoelectric (TE) conversion assemblies. In case of a loss of coolant or cooling in a reactor core sector, the power system continues to operate; generating ~4 kWe to the outpost for emergency life support needs. The post-operation storage of the reactor below grade on the lunar surface is a safe and practical choice. The total radioactivity in the reactor drops from ~1 million Ci, immediately at shutdown, to below 164 Ci after 300 years of storage. At such time, the reactor is retrieved safely with no contamination or environmental concerns.

    The aim of the study was to assess the sequential treatment performance of a commercial, domestic-scale modular reedbed system intended to provide safe horticultural irrigation water. Previously only mechanical treatment systems involving forced aeration with subsequent disinfection, usually by tablet-chlorination, had been accredited in Australia. The modular design of the hybrid, subsurface-flow reedbed system offered 5 control points where monitoring and management of the treatment train could be carried out. Ten chemical parameters (chemical and biochemical oxygen demand, total organic carbon, total Kjeldahl nitrogen, ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, total nitrogen, dissolved oxygen percentage saturation and suspended solids) and 4 microbial parameters (total coliform, Escherichia coli, enterococci and Clostridium perfringens) reached satisfactory levels as a result of the treatment process. Health requirements for safe horticultural irrigation were met by the outlet of the second reedbed, providing a high level of treatment-backup capacity in terms of the remaining 2 reedbeds. This suggested that chlorination was a redundant backup precaution in treating irrigation water to the acceptable regional guideline level for all horticultural uses, including the spray irrigation of salad crops eaten raw.

  8. Laminar-flow Liquid-to-air Heat Exchangers - Energy-efficient Display Cabinet Applications

    Energy Technology Data Exchange (ETDEWEB)

    Haglund Stignor, Caroline

    2009-02-15

    Provisions are stored and displayed in supermarkets and grocery stores, at a temperature lower than the ambient, in display cabinets, which are responsible for a significant amount of the energy use in this sector. During the 1990s, major changes in the regulations governing the use of synthetic refrigerants took place in Sweden. This resulted in many refrigeration systems being converted to systems with indirect cooling by means of a liquid secondary refrigerant. The cooling coil is an important component in a display cabinet and traditionally, different kinds of tube-coils, with aluminium fins on expanded circular copper tubes, have been used. Many secondary heat transfer media have relatively high viscosities at low temperatures, and so the flow regime is often laminar, which may lead to poor heat transfer. However, it is possible to achieve high heat transfer coefficients even for laminar flows if an appropriate design of the heat exchanger is applied. Flat-tube heat exchangers have been used for a long time in automotive applications, where compactness is important. The display cabinet application involves low air velocities in combination with condensation of water vapour, and sometimes even frosting, and is therefore different from other applications where flat-tube heat exchangers have been used earlier. The objective of this research work has been to find a suitable, more energy efficient, heat exchanger design for indirectly cooled display cabinets. An efficiency that would mean that temperature differences would be so small that frosting could be avoided was aimed for. This research work has sandwiched experimental investigations with theoretical modelling and parameter studies. Initially, the heat transfer and pressure drop performance of conventional cooling coils operating with liquid secondary refrigerants was studied in fullscale experiments. Thereafter, the liquid-side (or tube-side) heat transfer was studied experimentally in small

  9. Design and clinical application of safe air-pressure reduction system for intussusception

    International Nuclear Information System (INIS)

    This study was performed to design a safe air-pressure reduction system which can absorb rapidly rising intraluminal pressure during intussusception, and comparison with other reduction systems to test its clinical availability. The air-pressure reduction system consisted of a pressure gauge, air insufflators, a pressure controller, buffers, and rapid exhaustion devices, and to determine its absorbability, it was connected with a bowel model. By using it in 20 infants with intussusception, we compared the absorbability of our air-pressure reduction system with preexisting systems. While extraluminal pressure was applied to the bowel model in which baseline intraluminal pressure was set to 120mmHg, this rose to 176mmHg (56mmHg high to standard, 100%) in the direct infusion system, but to only 130mmHg (10mmHg high to standard, 17.9%) in a system connected to a large buffer of 10,500mL capacity. Immediately after the application of extraluminal pressure for less than 1 sec, this air-pressure reduction system showed better asorbability than the hydrostatic reduction system. Applying this system to 20 infants with intussusception, this was successfully reduced in 19 cases(95%), without complications. In this experiment, it was proved that the system absorbed rapid intraluminal pressure elevation. Its use would help prevent bowel perforation during air reduction occurring during intussusception.=20

    The goal of the present study is to develop a potent and safe vaccine adjuvant that can also stabilize vaccine formulations during lyophilization and storage. Inulin is a safe plant polysaccharide, and in its water soluble isoform, it is known to stabilize protein formulations during storage. However, soluble inulins have never been shown to stimulate the immune system. In this study, for the first time, we showed that water soluble inulins could be developed into vaccine adjuvants by formulating as antigen encapsulated microparticles. A method was developed to prepare soluble inulin microparticles (sIMs) with high encapsulation efficiency (∼75%) and loading (∼75 μg/mg) of the antigen. When immunized in mice, sIMs have generated robust Th2-type antibody titers (IgG1: 500,000) compared to unadjuvanted antigens (IgG1: 17,500) or alum adjuvanted antigens (IgG1: 80,000). In vitro assays showed that a higher proportion of antigen presenting cells (APC's) have taken up the antigen when presented in sIMs versus in solution (99 % vs 22 %). In addition, the amount of antigen taken up per cell has also been enhanced by more than 25 times when antigen was presented in sIMs. Efficient uptake of the antigen by APCs through sIMS was attributed to the observed enhancement in the immune response by antigen loaded sIMs. The sIMs neither caused any granuloma/tissue damage at the injection site in mice nor were they toxic to the APC's in cell culture. In conclusion, the current study has developed a safe, soluble inulin based vaccine adjuvant and delivery system. PMID:23506468

    NASA has been pursuing flash lidar technology for autonomous, safe landing on solar system bodies and for automated rendezvous and docking. During the final stages of the landing from about 1 kilometer to 500 meters above the ground, the flash lidar can generate 3-Dimensional images of the terrain to identify hazardous features such as craters, rocks, and steep slopes. The onboard flight computer can then use the 3-D map of terrain to guide the vehicle to a safe location. As an automated rendezvous and docking sensor, the flash lidar can provide relative range, velocity, and bearing from an approaching spacecraft to another spacecraft or a space station. NASA Langley Research Center has developed and demonstrated a flash lidar sensor system capable of generating 16,000 pixels range images with 7 centimeters precision, at 20 Hertz frame rate, from a maximum slant range of 1800 m from the target area. This paper describes the lidar instrument and presents the results of recent flight tests onboard a rocket-propelled free-flyer vehicle (Morpheus) built by NASA Johnson Space Center. The flights were conducted at a simulated lunar terrain site, consisting of realistic hazard features and designated landing areas, built at NASA Kennedy Space Center specifically for this demonstration test. This paper also provides an overview of the plan for continued advancement of the flash lidar technology aimed at enhancing its performance to meet both landing and automated rendezvous and docking applications.

    Full Text Available Nonambulatory, visually impaired individuals mostly rely on caregivers for their day-to-day mobility needs. The Drive-Safe System (DSS is a modular, semiautonomous smart wheelchair system aimed at providing independent mobility to people with visual and mobility impairments. In this project, clinical evaluation of the DSS was performed in a controlled laboratory setting with individuals who have visual impairment but no mobility impairment. Their performance using DSS was compared with their performance using a standard cane for navigation assistance. Participants rated their subjective appraisal of the DSS by using the National Aeronautics and Space Administration-Task Load Index inventory. DSS significantly reduced the number and severity of collisions compared with using a cane alone and without increasing the time required to complete the task. Users rated DSS favorably; they experienced less physical demand when using the DSS, but did not feel any difference in perceived effort, mental demand, and level of frustration when using the DSS alone or along with a cane in comparison with using a cane alone. These findings suggest that the DSS can be a safe, reliable, and easy-to-learn and operate independent mobility solution for visually impaired wheelchair users.

    Adzimah K. Stephen

    2009-01-01

    Full Text Available Problem statement: Grains are routinely seen dumped in villages and major cities during the peak of harvest. Therefore it is necessary that these grains are properly dried and stored to ensure availability and wholesomeness throughout the year. Advancements have taken place in the practice of drying since the first world war. Manufacturing methods have greatly improved production rate and the production line bottle-neck created by extended drying time inherent in the use old drying methods can no longer be tolerated. Main objectives of this study were to improve on the design of an existing cabinet grain dryer (to redesign the already existing cabinet grain dryer so as to: (i Optimize efficiency at low cost (ii Reduce total time of drying (iii Produce viable and quality grain. Approach: The improvement on the design of the existing cabinet dryer had been achieved through proper focus on the selection of power source, materials and other design criteria for the various components of the existing one. The dryer consists of a cabinet containing trays in which the grains to be dried are spread. After the grains were loaded, the cabinet closed and heated air of about 35-40°C blown across the grains. Heat was supplied by an electrical heating coil and hot air was blown from the heater housing to the drying chamber by the aid of a fan. The dryer also consisted of a thermostat which turns off the machine if inlet temperature exceeds 40°C. Results: The result of the improvement on the design of a cabinet grain dryer showed that; (i It was less costly (ii It was cheap to maintain since the fan is the only moving component and can hardly become faulty (iii drying time of the grain was reduced (iv The machine ergonomic; operation of the machine does not require specialization (v The machine is safer to operate since the use of gas has been eliminated (vi Time between two batches was reduced with the introduction of a trolley (vii Energy for loading or

    Lidar has been identified by NASA as a key technology for enabling autonomous safe landing of future robotic and crewed lunar landing vehicles. NASA LaRC has been developing three laser/lidar sensor systems under the ALHAT project. The capabilities of these Lidar sensor systems were evaluated through a series of static tests using a calibrated target and through dynamic tests aboard helicopters and a fixed wing aircraft. The airborne tests were performed over Moon-like terrain in the California and Nevada deserts. These tests provided the necessary data for the development of signal processing software, and algorithms for hazard detection and navigation. The tests helped identify technology areas needing improvement and will also help guide future technology advancement activities.

    This contribution details the deployment of Rucio, the ATLAS Distributed Data Management system. The main complication is that Rucio interacts with a wide variety of external services, and connects globally distributed data centres under different technological and administrative control, at an unprecedented data volume. It is therefore not possibly to create a duplicate instance of Rucio for testing or integration.

    Exploration and expansion of the chemistries involving toxic or carcinogenic reagents are severely limited by the health hazards their presence poses. Here, we present a micro-total envelope system (μ-TES) and an automated total process for the generation of the carcinogenic reagent, its purification and its utilization for a desired synthesis that is totally enveloped from being exposed to the carcinogen. A unique microseparator is developed on the basis of SiNWs structure to replace the usual exposure-prone distillation in separating the generated reagent. Chloromethyl methyl ether chemistry is explored as a carcinogenic model in demonstrating the efficiency of the μ-TES that is fully automated so that feeding the ingredients for the generation is all it takes to produce the desired product. Syntheses taking days can be accomplished safely in minutes with excellent yields, which bodes well for elevating the carcinogenic chemistry to new unexplored dimensions. PMID:26916423

  6. An Embedded System for Safe, Secure and Reliable Execution of High Consequence Software

    MCCOY,JAMES A.

    2000-08-29

    As more complex and functionally diverse requirements are placed on high consequence embedded applications, ensuring safe and secure operation requires an execution environment that is ultra reliable from a system viewpoint. In many cases the safety and security of the system depends upon the reliable cooperation between the hardware and the software to meet real-time system throughput requirements. The selection of a microprocessor and its associated development environment for an embedded application has the most far-reaching effects on the development and production of the system than any other element in the design. The effects of this choice ripple through the remainder of the hardware design and profoundly affect the entire software development process. While state-of-the-art software engineering principles indicate that an object oriented (OO) methodology provides a superior development environment, traditional programming languages available for microprocessors targeted for deeply embedded applications do not directly support OO techniques. Furthermore, the microprocessors themselves do not typically support nor do they enforce an OO environment. This paper describes a system level approach for the design of a microprocessor intended for use in deeply embedded high consequence applications that both supports and enforces an OO execution environment.

  8. Increased information on waterborne outbreaks through efficient notification system enforces actions towards safe drinking water.

    Zacheus, Outi; Miettinen, Ilkka T

    2011-12-01

    In 1997, a compulsory notification system for waterborne outbreaks was introduced in Finland. The main aim of this notification is to obtain immediate information on suspected waterborne outbreaks in order to restrict and manage the outbreak promptly. During the past ten years, there have been 67 waterborne outbreaks in Finland, mainly associated with small groundwater supplies or private wells. The number of reported waterborne outbreaks has increased since the launch of the notification system indicating that the threshold limit of outbreak detection has most probably decreased. The number of cases of illness has fulfilled the national health target, which is below 0.01% of the population, but more action is still needed to ensure the production of safe drinking water under all circumstances. Ten years accumulation of knowledge on outbreaks has revealed that a compulsory notification system is an effective tool to gather information on waterborne outbreaks. The system has also increased awareness of possible problems related to the quality of drinking water. This article summarises management and legislative actions and policy measures taken so far in Finland to reduce the number of outbreaks and cases of illness related to them. PMID:22048435

  9. Passive safe small reactor for distributed energy supply system sited in water filled pit at seaside

    International Nuclear Information System (INIS)

    Japan Atomic Energy Research Institute has developed a Passive Safe Small Reactor for Distributed Energy Supply System (PSRD) concept. The PSRD is an integrated-type PWR with reactor thermal power of 100 to 300 MW aimed at supplying electricity, district heating, etc. In design of the PSRD, high priority is laid on enhancement of safety as well as improvement of economy. Safety is enhanced by the following means: i) Extreme reduction of pipes penetrating the reactor vessel, by limiting to only those of the steam, the feed water and the safety valves, ii) Adoption of the water filled containment and the passive safety systems with fluid driven by natural circulation force, and iii) Adoption of the in-vessel type control rod drive mechanism, accompanying a passive reactor shut-down device. For improvement of economy, simplification of the reactor system and long operation of the core over five years without refueling with low enriched UO2 fuel rods are achieved. To avoid releasing the radioactive materials to the circumstance even if a hypothetical accident, the containment is submerged in a pit filled with seawater at a seaside. Refueling or maintenance of the reactor can be conducted using an exclusive barge instead of the reactor building. (author)

  10. SAFE-KBS, Substantiating the safety of systems containing knowledge-based components

    International Nuclear Information System (INIS)

    The overall objective of the Safe-KBS project is to develop generic development and certification methodologies that allow the introduction of knowledge-based components in safety-related applications. The expert system technology presents a set of features, such as the capability to provide the rationale for its conclusions, that may significantly contribute to the new operation support systems. Nevertheless, the use of this technology in safety-related applications is limited by the lack of recognised methodologies and standards that allow a formal demonstration of the quality and reliability of these systems, as required for obtaining the approval for their use at nuclear power plants. The development methodology is structured in three hierarchical levels: life cycle model, i.e., processes and activities constituting the life cycle, life cycle plans, i.e., tasks, and support packages, i.e., set of techniques and methods to perform certain activities or tasks. The certification methodology consists of a set of certification requirements and a certification scheme for demonstrating the compliance with these requirements.

    A cabinet with a set of protective equipment for shunting reactors has been developed by the All-Union Scientific Research Institute of Relay Engineering. This Sh2104 cabinet houses relays for protection and control of compensating reactors as well. The equipment will protect a reactor whether the latter is connected into the line directly or through a tripping switch, by disconnecting it from the line or by actuating that switch respectively. For better reliability, the equipment for protection of shunting relays is grouped into a main set and a backup set. The main set includes longitudinally-acting differential phase-current relays, lead high-voltage insulation checkers, gas-leak protection, and standby reactor or line disconnectors. The backup set includes a 2-step zero-sequence current relay. The equipment for protection of compensating reactors consists of longitudinally acting differential current relays, distance relays, peak-current relays, and gas-leak protection. Two power supplies (50 W and 100 W) are provided for energizing all the equipment in this cabinet. Provided are also means for continuous operational monitoring and spot-check testing. The overall dimensions are 600x600x2200 mm/sup 3/, the total weight is 250 kg.

    Full Text Available Recently, new definitions of shielding effectiveness (SE for high-frequency and transient electromagnetic fields were introduced by Klinkenbusch (2005. Analytical results were shown for closed as well as for non closed cylindrical shields. In the present work, the shielding performance of different shielding cabinets is investigated by means of numerical simulations and measurements inside a fully anechoic chamber and a GTEM-cell. For the GTEM-cell-measurements, a downscaled model of the shielding cabinet is used. For the simulations, the numerical tools CONCEPT II and COMSOL MULTIPHYSICS were available. The numerical results agree well with the measurements. They can be used to interpret the behaviour of the shielding effectiveness of enclosures as function of frequency. From the measurement of the electric and magnetic fields with and without the enclosure in place, the electric and magnetic shielding effectiveness as well as the transient shielding effectiveness of the enclosure are calculated. The transient SE of four different shielding cabinets is determined and discussed.

    Shin, Hyunchul

    2014-01-01

    An emerging trend in the automobile industry is its convergence with information technology (IT). Indeed, it has been estimated that almost 90% of new automobile technologies involve IT in some form. Smart driving technologies that improve safety as well as green fuel technologies are quite representative of the convergence between IT and automobiles. The smart driving technologies include three key elements: sensing of driving environments, detection of objects and potential hazards, and the generation of driving control signals including warning signals. Although radar-based systems are primarily used for sensing the driving environments, the camera has gained importance in advanced driver assistance systems(ADAS). This book covers system-on-a-chip (SoC) designs—including both algorithms and hardware—related with image sensing and object detection by using the camera for smart driving systems. It introduces a variety of algorithms such as lens correction, super resolution, image enhancement, and object ...

    Anderson, Bernhard H.; Mace, James L.; Mani, Mori

    2009-01-01

    The primary objective of this research effort was to develop and analytically demonstrate enhanced first generation active "fail-safe" hybrid flow-control techniques to simultaneously manage the boundary layer on the vehicle fore-body and to control the secondary flow generated within modern serpentine or embedded inlet S-duct configurations. The enhanced first-generation technique focused on both micro-vanes and micro-ramps highly-integrated with micro -jets to provide nonlinear augmentation for the "strength' or effectiveness of highly-integrated flow control systems. The study focused on the micro -jet mass flow ratio (Wjet/Waip) range from 0.10 to 0.30 percent and jet total pressure ratios (Pjet/Po) from 1.0 to 3.0. The engine bleed airflow range under study represents about a 10 fold decrease in micro -jet airflow than previously required. Therefore, by pre-conditioning, or injecting a very small amount of high-pressure jet flow into the vortex generated by the micro-vane and/or micro-ramp, active flow control is achieved and substantial augmentation of the controlling flow is realized.

  19. Rocking stiffness of mounting arrangements in electrical cabinets and control panels

    International Nuclear Information System (INIS)

    Several studies have shown that the consideration of a rigid body-rocking mode in a cabinet is necessary to evaluate accurate incabinet spectra. Observations from finite element analyses are used to study cabinet rocking behavior and to show that accurate representation of the boundary conditions at the cabinet base is essential in the evaluation of correct rocking mode. Simple formulations for evaluating the rocking stiffness are developed by conducting detailed analytical studies for three different types of cabinet mounting arrangements. Availability of these formulations enables incorporation of a cabinet rocking mode in the Ritz vector approach [Nucl. Eng. Des. 190 (1990) 225] for evaluating the cabinet dynamic properties in significant mode and for generating the incabinet response spectra

    An evaluation of a special safety cabinet housing a high-speed centrifuge was made. The cabinet enclosed both the top access port and the drive and pumping machinery of the centrifuge. A titanium rotor was loaded with tubes containing a bacterial culture, weakened, and driven until rotor rupture occurred. There were several bent and broken components in the centrifuge, and bacteria leaked from the vacuum chamber. Although the forces were sufficient to displace the cabinet, none of the test bacteria were found outside the cabinet. PMID:543704

  2. Quantitative assessment of probability of failing safely for the safety instrumented system using reliability block diagram method

    International Nuclear Information System (INIS)

    Highlights: • Models of PFS for SIS were established by using the reliability block diagram. • The more accurate calculation of PFS for SIS can be acquired by using SL. • Degraded operation of complex SIS does not affect the availability of SIS. • The safe undetected failure is the largest contribution to the PFS of SIS. - Abstract: The spurious trip of safety instrumented system (SIS) brings great economic losses to production. How to ensure the safety instrumented system is reliable and available has been put on the schedule. But the existing models on spurious trip rate (STR) or probability of failing safely (PFS) are too simplified and not accurate, in-depth studies of availability to obtain more accurate PFS for SIS are required. Based on the analysis of factors that influence the PFS for the SIS, using reliability block diagram method (RBD), the quantitative study of PFS for the SIS is carried out, and gives some application examples. The results show that, the common cause failure will increase the PFS; degraded operation does not affect the availability of the SIS; if the equipment was tested and repaired one by one, the unavailability of the SIS can be ignored; the corresponding occurrence time of independent safe undetected failure should be the system lifecycle (SL) rather than the proof test interval and the independent safe undetected failure is the largest contribution to the PFS for the SIS

    2010-08-01

    Full Text Available Due to the particular geographical location and geological condition, Taiwan is constantly attacked by typhoons, flood, landslides, debris flows, and earthquakes. Those natural hazards had caused huge loss of lives and properties. To reduce the damages and losses caused by the natural hazards, an integrated and complete decision support system for decision makers is necessary. In this study, Safe Taiwan information system (SATIS, which includes two subsystems, response operation subsystem for staff members and decision support subsystem for commanders, is developed for preparedness and response of typhoon hazards. It is based on the Web- GIS framework that the disaster information can be distributed via internet technology. When typhoon is approaching, response operation subsystem is used by National Science and Technology Center for Disaster Reduction (NCDR staffs to integrate real-time monitoring information, hazard models and graphical user interfaces to analyze and manage the disaster information such as the current position and possible path of typhoon, the spatial distribution of rainfalls, and potential areas of flooding, landslides and debris flows. The input data of this subsystem includes the basic maps, the real-time information of typhoon and rainfall issued by the Central Weather Bureau, the real-time water information from the Water Resources Agency, and the hazard maps indicating areas of potential landslide, debris flow and flooding made by NCDR herself to estimate endangered areas under the current typhoon. There are four main modules integrated into the subsystem including the rainfall monitoring and forecasting, the estimation of potential inundation areas, the estimation of potential landslide and debris flows, and the management of disaster information. The results of hazard risk analysis which include potential rainfall distribution, inundation and landslide risk areas, early warning messages, and total suggestion over the

    Editorial commentary focused on several Health System Research (HSR) approaches which exemplified some of the key issues for application of HSR for further improvement in Maternal and Child Health (MCH) services in India. The goals of HSR are to delineate health policy which improves the operations of the health care delivery system for sustainability at the district level. HSR is part of a global effort of Health For All by 2000 AD and India's Child Survival and Safe Motherhood (CSSM) program, sponsored by IDA/UNICEF. CSSM aims also to end polio by 2000 AD, eliminate neonatal tetanus by 1995, and prevent deaths and morbidity from measles, diarrheal diseases, and acute respiratory infection. MCH services will be expanded at the village, subcenter, primary health center, and community health center levels in order to reduce maternal mortality to below 2/1000 from the 1990 5/1000 and to reduce mortality of children aged 1-4 years to less than 10/1000 live births from 80/1000 by 2000 AD. States with particularly high levels of child and maternal mortality are Bihar, Uttar Pradesh, Rajasthan, and Madhya Pradesh, which have about 40% of India's population. These states have low marriage ages, low female literacy, and few women in nonagricultural employment. There are about 90 districts in these states with particularly low demographic indicators. India policy directs all CSSM work to be carried out by existing staff; the program emphasis will be training, supervision, and logistics. IEC will need to be directed to attitudinal change in rural areas and urban slums. Research has found that coverage is uneven and quality of MCH services, poor. One study will evaluate the performance over 5 years in Gwalior district in a nutrition and school health program. Another research effort will perform quality assessment of MCH care at the primary health care level and promote community awareness and increased utilization. An ongoing study is evaluating nationally the family welfare

  5. Reactivity control system of a passively safe thorium breeder pebble bed reactor

    International Nuclear Information System (INIS)

    Highlights: • A worth of over 15,000 pcm ensures achieving long-term cold shutdown in thorium PBR. • Control rod worth in side reflector is insufficient due to low-power breeder zone. • 20 control rods, just outside the driver zone, can achieve long-term cold shutdown. • BF3 gas can be inserted for reactor shutdown, but only in case of emergency. • Perturbation theory accurately predicts absorber gas worth for many concentrations. - Abstract: This work investigates the neutronic design of the reactivity control system for a 100 MWth passively safe thorium breeder pebble bed reactor (PBR), a conceptual design introduced previously by the authors. The thorium PBR consists of a central driver zone of 100 cm radius, surrounded by a breeder zone with 300 cm outer radius. The fissile content of the breeder zone is low, leading to low fluxes in the radial reflector region. Therefore, a significant decrease of the control rod worth at this position is anticipated. The reactivity worth of control rods in the side reflector and at alternative in-core positions is calculated using different techniques, being 2D neutron diffusion, perturbation theory and more accurate 3D Monte Carlo models. Sensitivity coefficients from perturbation theory provide a first indication of effective control rod positions, while the 2D diffusion models provide an upper limit on the reactivity worth achievable at a certain radial position due to the homogeneous spreading of the absorber material over the azimuthal domain. Three dimensional forward calculations, e.g. in KENO, are needed for an accurate calculation of the total control rod worth. The two dimensional homogeneous calculations indicate that the reactivity worth in the radial reflector is by far insufficient to achieve cold reactor shutdown, which requires a control rod worth of over 15 000 pcm. Three dimensional heterogeneous KENO calculations show that placing 20 control rods just outside the driver channel, between 100 cm and

    A large amount of hazardous trichloromonofluoromethane (CFC-11) is contained in the polyurethane (PUR) foam of refrigerator cabinet. How to recover the cabinet of waste refrigerator with environmental awareness has been the pressing problem in the treatment of waste refrigerator. The published literature of waste refrigerator cabinets recovering mainly focuses on policy making and conceptual design. Little information relates to the production line of waste refrigerator cabinet recovering and its detailed operation, which is the urgent needed literature. In this paper, an environmental friendly production line for recovering the cabinet of waste refrigerators was reported for helping enterprise or government to construct line to recover the obsolete refrigerators. It included closed shearing process, activated carbon fiber absorption (ACFA) process, air current separation, and magnetic/eddy current separation. The optimized operating parameters of every process were obtained from the experiments. Then, experiment of recovering 50 waste refrigerator cabinets by the production line was performed in factory. Mass balances of the recovered materials were carried out. The result shown the recovery rate of waste refrigerator cabinet could reach 97.6%. Finally, comparison between the production line and other recovery technologies was made. The results indicated that the proposed line provided environment-friendly recovery of waste refrigerator cabinets while achieving low cost of production. PMID:21782408

    Along the past few years, there has been intensive research on clean and renewable energy production. Two main reasons have been pointed out: pollution caused by oil based fuels consumption and their availability diminution, which increases their production costs. Fuel Cells have shown to be a clean and renewable energy source, which reveals them as a promising solution, although their technology needs further development. Fuel Cells produce electricity, water and heat consuming hydrogen and oxygen, this provided pure or from a natural air source. Present research has combined different equipment to compose a self-sustaining fuel cells technology based cabinet for energy production, which is a Regenerative Fuel Cell System (RFC). This system contains: fuel cells stack, electrolyzer, photovoltaic panel, batteries, current inverter and a charge controller. Photovoltaic panel charges the batteries, while charge controller controls the batteries loading. Batteries are connected to an inverter which converts direct current into alternating current. Inverter is connected to an electrolyzer (Hogen GC 600) which splits the water molecule into hydrogen and oxygen molecules. Produced hydrogen supplies the fuel cell stack and the oxygen is released directly to the atmosphere. Fuel cell stacks power production is transformed into mechanical energy by a fan. Electrical power generated by Ballard stack is 5.124 W, with a voltage of 36.6 V and current of 0.14 A. The system proved to have a great efficiency and to be capable to assemble two renewable energy sources (solar and fuel cell technology) in a self-sustainable cabinet. It has also been shown that equipment such as Electrolyzer, Fuel Cell Stack and Photovoltaic panel can be fit together in the order to produce energy. Therefore, research on Fuel Cells Regenerative System reveals great importance for developing a new, clean, renewable and regenerative energy production system. (author)

    2008-07-01

    Full Text Available Perception of moving sound sources obeys different brain processes from those mediating the localization of static sound events. In view of these specificities, a preprocessing model was designed, based on the main perceptual cues involved in the auditory perception of moving sound sources, such as the intensity, timbre, reverberation, and frequency shift processes. This model is the first step toward a more general moving sound source system, including a system of spatialization. Two applications of this model are presented: the simulation of a system involving rotating sources, the Leslie Cabinet and a 3D sound immersion installation based on the sonification of cosmic particles, the Cosmophone.

    This work presents a powerful computational tool (Stochastic Toxic Release Risk Assessment Package, STRRAP) useful in risk assessment and emergency planning (safe distance calculation), which allows to handle the stochastic uncertainty of atmospheric parameters, critical for risk calculation when diffusion of hazardous gases or particulate matter occur as a consequence of an emission or accidental release. In fact, the random behaviour of wind intensity, wind direction, atmospheric stability and temperature, given a time horizon, (a season or a complete year), is taken into account considering also the day or night condition. STRRAP can be used for releases or emissions from static sources (for example a stack or a fixed tank in a facility) or from transportation accidents (road, rail, maritime and pipeline transport) involving different scenarios. After a stochastic simulation based on well-known diffusion models (dense and light gases, particulate matter) is carried out, the downwind pollutant concentrations are obtained, in order to compute safe distances and/or individual and societal risks. Some study cases are analyzed to show STRRAP capabilities.

    This paper introduces the Cabinet Office's Civil Contingencies Secretariat (CCS). It explains how the National Risk Assessment, produced within the CCS, is created and used. As part of the recent Strategic Defence and Security Review, the Government made a commitment to improve the business continuity of small and medium-sized enterprises (SMEs).This paper describes the CCS's approach to achieving this, and explains why the resilience of SMEs is important to both local communities, at a time of disruption or crisis, and the essential services sectors, such as energy, food and transport. It provides an outline of a strategic approach that will seek to simplify business continuity by making it accessible, achievable and affordable, and, in partnership with the organisations that SMEs turn to for advice, promotes the benefits of business continuity and encourages its use.

  20. A simplified model for nonlinear seismic response analysis of equipment cabinets in nuclear power plants

    International Nuclear Information System (INIS)

    Highlights: · Reduction in dynamic stiffness of cabinets of NPPs with increase in excitation level. · Simplified nonlinear model presented for seismic response analysis of cabinets. · Nonlinear behavior taken into account by considering equivalent nonlinearity. · Accurate prediction of softening, less computational effort and no tests required. - Abstract: An analytical model is required when the analysis method or the combined analysis and modal testing method is used as an aid to the seismic qualification (SQ) of equipment cabinets within nuclear power industry. This study proposes a simplified and computationally efficient model to represent the nonlinear dynamic behavior of the cabinet during earthquake. The presented model accounts for the softening behavior of the cabinets by incorporating the Duffing's type of restoring force. The characteristic of nonlinear restoring force for the finite element model (FEM) is based on the relationship of stress-strain of the element. Experiments have also been performed on an actual cabinet of nuclear power plant (NPP) to validate the model. The softening or reduction in dynamic stiffness of cabinets with increase in the excitation levels is observed in the experiments. It is also found that material yielding is not a significant source of the nonlinear behavior of the cabinet. The results obtained from the analysis using the proposed model are found to be in good agreement with the experimental results. The proposed model is expected to be useful for the prediction of seismic behavior of cabinets, particularly during the operation, owing to less computational effort required, accurate prediction of softening and no requirement of tests.

  1. Crystals YAG doped with Er3+ and Yb3+ for laser 'eye safe' systems

    International Nuclear Information System (INIS)

    Considerable interest in compact pulsed high-peak power lasers sources emitting at wavelengths near 1,55 μm is observed. Rangefinders and other applications with free space propagation could be strong benefit of such devices. The wavelength of about 1.55 μm is in the eye safe regime where significantly higher pulse energies can be used without damage of human eyes. Erbium and ytterbium doped YAG single crystals were obtained by the Czochralski method. Fundamental conditions of growth of the obtained crystals and the results of optical homogeneity measurements are presented. Absorption spectra of Er3+ and Yb3+ - doped YAG crystals were measured in a spectral range 190-5000 nm at room temperature. Excitation and luminescence spectra were also recorded at room temperature with a JOBINYVON spectrofluorometer using a diode laser (POLAROID 4300, 970 nm, 1 W) as an excitation source. Measurements of lifetime of Er3+ ions in the upper laser level 4I13/2) of the samples were made by a direct method with pulse excitation. (author)

  6. What Food is to be Kept Safe and for Whom? Food-Safety Governance in an Unsafe Food System

    Directory of Open Access Journals (Sweden)

    Martha McMahon

    2013-10-01

    Full Text Available This paper argues that discussion of new food-safety governance should be framed by the realization that the dominant food system within which food-safety governance is designed to makes food safe is itself a structural and systemic sources of food un-safety, poor health and a future of food insecurity for many. For some, an appropriate policy response lies in addressing the connections between the food system and diseases such as heart disease, obesity and diabetes. For others it means subsuming food-safety governance within food security governance. For yet others, safe food implies food sovereignty governance and the primacy of a climate change resilient food system. Conventional approaches to food-safety governance are typically framed within a liability model of responsibility that has limited usefulness for addressing institutional, structural or systemic sources of harm such as those critics increasingly attribute to the dominant food system and which are not amenable to remedy by food-safety governance as it is widely understood. One cannot identify critical hazard points where risk is to be managed. These are food-system safety challenges. Because food-safety governance is so deeply political there needs to be greater attention to issues of governance rather than the more usual focus on the technologies of food-safety. Feminist political theorists have much to contribute to re-thinking food-safety governance in the context of diversity and the complexities of power. One could usefully start with the simple questions, “what food is to be kept-safe, for whom and who is the subject of food-safety governance in a post-Westphalian political economic order?” These questions can help unpack both the narrow parochialism and the misleading universalism of food-safety talk. This paper answers that neither the citizens of a particular state (or network of states nor the falsely universalizing identity of ‘the consumer’ are adequate answers

    Since the return to democracy, Uruguayan presidents have built cabinets of varying natures (majority and minority coalitions, majority and minority parties). Most studies on presidential government assume that the partisan composition of a cabinet is a good predictor of the performance of a government’s legislative program. In this paper I test this hypothesis using Cox and McCubbins’ (1993, 2005) party cartel theory. The results confirm that six o...

    2009-01-01

    Long duration human space missions, as planned in the Vision for Space Exploration, will not be possible without applying unprecedented levels of automation to support the human endeavors. The automated and robotic systems must carry the load of routine housekeeping for the new generation of explorers, as well as assist their exploration science and engineering work with new precision. Fortunately, the state of automated and robotic systems is sophisticated and sturdy enough to do this work - but the systems themselves have never been human-rated as all other NASA physical systems used in human space flight have. Our intent in this paper is to provide perspective on requirements and architecture for the interfaces and interactions between human beings and the astonishing array of automated systems; and the approach we believe necessary to create human-rated systems and implement them in the space program. We will explain our proposed standard structure for automation and robotic systems, and the process by which we will develop and implement that standard as an addition to NASA s Human Rating requirements. Our work here is based on real experience with both human system and robotic system designs; for surface operations as well as for in-flight monitoring and control; and on the necessities we have discovered for human-systems integration in NASA's Constellation program. We hope this will be an invitation to dialog and to consideration of a new issue facing new generations of explorers and their outfitters.

  9. Modified Ritz vector approach for dynamic properties of electrical cabinets and control panels

    International Nuclear Information System (INIS)

    Often, the simple methods used for evaluating incabinet spectra needed in the seismic qualification of safety related electrical instruments ignore the dynamic characteristics of the electrical control panels and cabinets. Gupta et al. (Nucl. Eng. Des. 190 (1999a) 255) developed a Ritz vector approach for evaluating the dynamic properties of the cabinets and the incabinet spectra. This approach is based on the conclusions drawn from detailed finite element analyses of several cabinets. In the present paper, we illustrate the limitations of the originally proposed Ritz vector approach that were encountered during subsequent applications to actual cabinets. Modifications to the originally proposed formulations are presented and their accuracy evaluated by comparison of results for actual cabinets with the corresponding results obtained from finite element analyses. The modified Ritz vector approach can account for actual rotational constraints imparted by supporting structural members such as stiffeners. It can also be applied to bench board type cabinets in which instruments are mounted on plates or frames that are inclined to the global axes as well as to frames in which parallel frame members can vibrate in different vibration shapes due to differences in boundary conditions and non-uniform mass distribution

    Safety must be ensured during all phases of space fission system design, development, fabrication, launch, operation, and shutdown. One potential space fission system application is fission electric propulsion (FEP), in which fission energy is converted into electricity and used to power high efficiency (Isp greater than 3000s) electric thrusters. For these types of systems it is important to determine which operational scenarios ensure safety while allowing maximum mission performance and flexibility. Space fission systems are essentially nonradioactive at launch, prior to extended operation at high power. Once high power operation begins, system radiological inventory steadily increases as fission products build up. For a given fission product isotope, the maximum radiological inventory is typically achieved once the system has operated for a length of time equivalent to several half-lives. After that time, the isotope decays at the same rate it is produced, and no further inventory builds in. For an FEP mission beginning in Earth orbit, altitude and orbital lifetime increase as the propulsion system operates. Two simultaneous effects of fission propulsion system operation are thus (1) increasing fission product inventory and (2) increasing orbital lifetime. Phrased differently, as fission products build up, more time is required for the fission products to naturally convert back into non-radioactive isotopes. Simultaneously, as fission products build up, orbital lifetime increases, providing more time for the fission products to naturally convert back into non-radioactive isotopes. Operational constraints required to ensure safety can thus be quantified.

    The integrity of reactor core could be preserved if there was a passive safety system enough to remove the decay heat in the Fukushima accident. Also, even if the core was molten and there was no electrical power, the reactor vessel would not be damaged and the release of radioactive materials could be prevented by using safety systems of containment cooling and filtered venting. Not only for the Fukushima accident, there is a possibility that a nuclear power plant can experience a severe accident in a case of SBO (Station Black Out). Even if it is sure that the reasonable proportion of active and passive safety system has to be considered based on the safety and economics of a nuclear power plant, the researches to enhance the safety of a nuclear power plant must be continued for the future. In order to solve the problem and enhance the safety of nuclear power plants, integrated passive safety system (IPSS) is proposed. It is the wholly passive system by natural phenomena like gravity, natural circulation and pressure difference. The purpose of this paper is to propose the conceptual design of the integrated passive safety system and make the overall evaluation of IPSS characters

  14. What is the safe upper intake level of folic acid for the nervous system? Implications for folic acid fortification policies.

    2016-05-01

    Between 1945 and 1959 it was convincingly documented that folic acid can precipitate or aggravate the neurological and haematological consequences of vitamin B12 deficiency by increasing the demand for vitamin B12. Since then there has been much misunderstanding of the issues, mainly by advocates of folic acid fortification who have been inclined to minimise or even dismiss the risks by misinterpreting the evidence as only a 'masking' of the anaemia of pernicious anaemia. Recent studies in the era of fortification are rediscovering the risks to the nervous system, especially cognitive function, of excess folate in the presence of vitamin B12 deficiency. I have reviewed the Reports of four Expert Advisory Committees in Europe and the USA, which suggest that the safe upper tolerable limit (UL) for folic acid is 1 mg in adults. These reports are unsound and there is already evidence of neurological harm from long-term exposure to doses of folic acid between 0.5 and 1 mg in the presence of vitamin B12 deficiency. There is an urgent need to review the safe UL for folic acid and to consider the addition of vitamin B12 to folic acid fortification policies. PMID:26862004

  16. Heat pipe based passive emergency core cooling system for safe shutdown of nuclear power reactor

    International Nuclear Information System (INIS)

    On March 11th, 2011, a natural disaster created by earthquakes and Tsunami caused a serious potential of nuclear reactor meltdown in Fukushima due to the failure of Emergency Core Cooling System (ECCS) powered by diesel generators. In this paper, heat pipe based ECCS has been proposed for nuclear power plants. The designed loop type heat pipe ECCS is composed of cylindrical evaporator with 62 vertical tubes, each 150 mm diameter and 6 m length, mounted around the circumference of nuclear fuel assembly and 21 m × 10 m × 5 m naturally cooled finned condenser installed outside the primary containment. Heat pipe with overall thermal resistance of 1.44 × 10−5 °C/W will be able to reduce reactor temperature from initial working temperature of 282 °C to below 250 °C within 7 h. The overall ECCS also includes feed water flooding of the core using elevated water tank for initial 10 min which will accelerate cooling of the core, replenish core coolant during loss of coolant accident and avoids heat transfer crisis phenomena during heat pipe start-up process. The proposed heat pipe system will operate in fully passive mode with high runtime reliability and therefore provide safer environment to nuclear power plants. - Highlights: • Completely passive emergency core cooling system (ECCS) for nuclear power plants. • ECCS consists of loop type heat pipe and initial feed water flooding system. • Overall thermal resistance of loop type heat pipe is 1.44 × 10−5 °C/W. • Heat pipe system can reduce reactor temperature from 282 °C to 250 °C in 7 h. • Proposed system will provide reliable and safer cooling for nuclear reactor

    Robust, active cooperation, and effective, open communication between all stakeholders is essential for ensuring regulatory compliance and healthcare product safety; avoiding the necessity for whistle-blowing; and, most essentially, meeting the transparency requirements of public trust.The focus here is on what can be done within a healthcare product organization (HPO) to achieve actionable, sustainable policies and practices such as leadership, management, and supervision role-modelling of best practice; ongoing process review and improvements in every department; protection of those who report concerns through robust policies endorsed at Board level throughout an organization to eliminate the fear of retaliation; training in open, non-defensive team-working principles; and mediation structure and process for resolution of differences of opinion or interpretation of contradictory and volatile data.Based on analyses of other safety systems, workplace silence and interpersonal breakdowns are warning signs of defective systems underlying poor compliance and compromising safety. Remedying the situation requires attention to the root causes underlying such symptoms of dysfunction, especially the human factor, i.e. those factors that influence human performance. It is essential that leadership and management listen to employees' concerns about systems and processes, assess them impartially and reward contributions that improve safety.Fundamentally, the safety, transparency, and trustworthiness of HPOs, both commercial and regulatory, can be judged by the extent of the freedom of their staff to 'speak up' when the time is right. This, in turn, consolidates the trust of external stakeholders in the safety of a system and its products. The promotion of 'speaking up' in an organization provides an important safeguard against the risk of poor compliance and the undermining of societal confidence in the safety of healthcare products.

  3. Development of inherently safe technologies for large scale BWRs. Technologies of heat transfer enhancement of air cooling system

    International Nuclear Information System (INIS)

    After the Fukushima accident, inherently safe technologies for large scale BWRs had been developed and consisted of passive water cooling system, infinite time air cooling system, prevention of hydrogen explosion prevention using SiC fuel claddings and operation support system for plant accidents. This article described development of air cooling system, which consisted of air cooled heat exchanger installed in the outer circumferential part of containment and heat transport system transporting decay heat produced steam to air cooled heat exchanger. Cover was attached outside peripheral part of air cooled heat exchanger, and air flow was generated by stack effect (buoyancy) and cooled heat exchanger targeted as much as 10MW heat removal. Compacting of heat exchanger was essential requisite and technologies of air cooling heat transfer enhancement had been developed. Combination of turbulence promotion ribs and micro fabrication surface, and heat transfer fins were tested and 36% and 65% respective increase in heat transfer were confirmed compared to bare tube, which showed heat transfer performance of air cooled heat exchanger could be enhanced by 100%.

  4. How safe is safe enough?

    International Nuclear Information System (INIS)

    The IAEA Regulations for the Safe Transport of Radioactive Material, were historically established with the objective to reduce the probability that persons be exposed to unacceptable doses due to normal operation or accident situations during transport of radioactive material. Based on the International Basic Safety Standards for Protection against Ionizing Radiation (BSS), the definition, which was adopted for an unacceptable dose for an accident situation, is the excess of the maximum dose limits permissible in a single year for the occupational exposure of a worker in the BSS. Concerning the severity of accident situations, it has always be clearly stated that the objective of the tests for demonstrating ability to withstand accident conditions of transport was not to cover every accident condition, but solely most of them. The last available evaluations regarding the rate of accidents which are covered by the standardised accident conditions of transport defined in the IAEA Regulations give a range of about 80%, plus or minus 15% which depends on transport mode and studies. Consequently, slight variations in the capabilities of the packages to meet the specified performance would probably not have significant consequences on the protection level in case of accident. In the assessment of the compliance with the regulations, the tendency of experts, taking advantage of the enhanced performances of computer calculation codes, is to ask more and more calculations, with more and more accuracy, leading to more and more restrictions. Consequently, cost and delay are considerably increased without any evidence of an equivalent effect on the level of protection. This paper will initiate a reflection on the general objectives and principles when implementing the Regulations, in such a way that demonstrations remain cost effective, taking into account evolution of the techniques and a high level of safety

    Sea ice monitoring and forecasting systems are important tools for minimizing accident risk and environmental impacts of Arctic maritime operations. Satellite data such as synthetic aperture radar (SAR), combined with atmosphere-ice-ocean forecasting models, navigation models and automatic identification system (AIS) transponder data from ships are essential components of such systems. Here we present first results from the SONARC project (project term: 2015-2017), an international multidisciplinary effort to develop novel and complementary ice monitoring and forecasting systems for vessels and offshore platforms in the Arctic. Automated classification methods (Zakhvatkina et al., 2012) are applied to Sentinel-1 dual-polarization SAR images from the Barents and Kara Sea region to identify ice types (e.g. multi-year ice, level first-year ice, deformed first-year ice, new/young ice, open water) and ridges. Short-term (1-3 days) ice drift forecasts are computed from SAR images using feature tracking and pattern tracking methods (Berg & Eriksson, 2014). Ice classification and drift forecast products are combined with ship positions based on AIS data from a selected period of 3-4 weeks to determine optimal vessel speed and routing in ice. Results illustrate the potential of high-resolution SAR data for near-real-time monitoring and forecasting of Arctic ice conditions. Over the next 3 years, SONARC findings will contribute new knowledge about sea ice in the Arctic while promoting safe and cost-effective shipping, domain awareness, resource management, and environmental protection.

    2010-01-01

    In early 2009, preliminary excavation work has begun in preparation for the construction of the New Safe Confinement (NSC) at the Chernobyl Nuclear Power Plant (ChNPP) in Ukraine. The NSC is the structure that will replace the present containment structure and will confine the radioactive remains of the ChNPP Unit-4 reactor for the next 100 years. It is expected that special nuclear material (SNM) that was ejected from the Unit-4 reactor during the accident in 1986 could be uncovered and would therefore need to be safeguarded. ChNPP requested the assistance of the United States Department of Energy/National Nuclear Security Administration (NNSA) with developing a new non-destructive assay (NDA) system that is capable of assaying radioactive debris stored in 55-gallon drums. The design of the system has to be tailored to the unique circumstances and work processes at the NSC construction site and the ChNPP. This paper describes the Chernobyl Drum Assay System (CDAS), the solution devised by Los Alamos National Laboratory, Sonalysts Inc., and the ChNPP, under NNSA's International Safeguards and Engagement Program (INSEP). The neutron counter measures the spontaneous fission neutrons from the {sup 238}U, {sup 240}Pu, {sup 244}Cm in a waste drum and estimates the mass contents of the SNMs in the drum by using of isotopic compositions determined by fuel burnup. The preliminary evaluation on overall measurement uncertainty shows that the system meets design performance requirements imposed by the facility.

    2013-09-01

    Full Text Available Aim: Questionnaires are an invaluable resource for clinical trials. They serve to estimate disease burden and clinical parameters associated with a particular study. However, current researchers are tackling budget constraints, loss of funding opportunities, and rise of research associated fees. We aimed at exploring alternative avenues taking advantage of the free Google docs software for questionnaire administration. This presents an opportunity to reduce costs while simultaneously increasing efficiency and data fidelity. Material and Methods: Google documents were used as a platform to create online questionnaires that were automatically hosted via a unique URL. Password protected access to the URL link and a unique study ID gave patients around the clock access from anywhere in the world. Unique study ID ensured confidentially of all self-reported data. Patient responses were secured using a “Cloud” database where the data was automatically sorted, scaled and scored by custom Excel formulas. Researchers downloaded real-time questionnaire responses in multiple formats (e.g. excel which was then analyzed with a statistical software of choice. Results: This simple workflow provided instant questionnaire scores that eliminated the use for paper-based responses and subsequent manual entry of data. Ease of access to online questionnaires provided convenience to patients leading to better response rates and increase in data fidelity. The system also allowed for real time monitoring of patient’s progress on completing questionnaires. Online questionnaires had 100% completion rate compared to paper-based questionnaires. Conclusions: Google docs can serve as an efficient and free platform to administer questionnaires to a clinical population without sacrificing quality, security, and fidelity of data.

    The electrical and instrumentation and control area of NPP Paks is upgraded with new switchgear cabinets. In connection with the emergency power supply a rectifier switchgear cabinet is installed. The electric components inside, especially the extensive control electronics, are designed according to the German safety standard KTA 3703 (1986) as well as to withstand a high level earthquake. Investigated switchgear cabinets constructed as steel frames have plan dimensions of 800 x 1600 mm and heights of 2200 mm as well as total masses of approximately 1400 kgs. For the required earthquake design of the switchgear cabinets with safety relevant components inside the present seismic design basis of Parks is used. Proof of global stability of the steel frame as well as the determination of earthquake loading for the electric components mounted to the steel frame are established by Finite-Element-Calculations. The functionability of electric components during and after an earthquake is tested with real components by experimental earthquake simulation. For similar cabinets and equal or similar electric components the functionability is proved by analogy. This contribution presents the course of calculation and performance of tests as well as selected results. (author). 3 refs., 9 figs

  9. Evaluation of modal properties of cabinet type instrument of nuclear power plant

    International Nuclear Information System (INIS)

    The seismic qualification of safety-related equipment is usually achieved through analysis and testing. Analysis method is preferably adopted for structurally simple equipments which are easy to be mathematically modeled. However, even for relatively complex equipments, analysis method is occasionlly used for computing the input motion or supporting information for the component test followed. Electrical cabinet is a typical example for which analysis method is combinedly used with test to get modal properties of the enclosing cabinet structure. In this paper, with respect to a typical cabinet-type structure(instrumentation cabinet of nuclear power plant) a comparative study has been performed between three different state-of-the-art modeling techniques: lumped mass model, frame model, and FEM modal. From the study results, it has been found that the modal properties of the cabinet-type structure in the elastic behavior range can be reasonably computed through any type of modeling techniques in the practice with slight modification of model properties to get better accuracy. However, it needs additional modeling techniques to get reasonable results up to nonlinear range

    The equipments in the machine room have great calorie power. The calorie power of different cabinet and the different part of a cabinet are also different. The position of the cabinets with different caloricity is indefinite, as a result, the machine room air conditioning can not satisfy the cooling. A cabinet on inequitable internal heat to cool "peer-to-peer" was presented. Through the experiment study ,for an evaporator with multi-channel ,increase the length of the boiling tube and supply the refrigerant separately ,can supply air with different temperature and realize a higher cooling efficiency. Another system equipped back pressure valves on the return gas pipe can realize supplying air with different temperature but the efficiency is lower.%机房设备具有发热量大、每个机柜发热量不同和个体机柜各个局部发热量不一致的特点.由于机房内不同发热量机柜摆放的不确定性,目前在用的机房空调不能满足降温要求.本文提出一种针对于个体机柜内部发热量不均进行"点对点"降温的机柜空调.通过试验研究可知,在一个机体上的多通路蒸发器,通过增加两个通路蒸发管长度,并与其它通路分开供液,可以实现非等温送风,且制冷系统具有较高的工作效率.另一种回气管路装有背压阀的系统虽能实现非等温送风,但制冷系统的效率较低.

    Full Text Available Abstract Background In 2000, the eight Millennium Development Goals (MDGs set targets for reducing child mortality and improving maternal health by 2015. Objective To evaluate the results of a new education and referral system for antenatal/intrapartum care as a strategy to reduce the rates of Cesarean sections (C-sections and maternal/perinatal mortality. Methods Design: Cross-sectional study. Setting: Department of Gynecology and Obstetrics, Botucatu Medical School, Sao Paulo State University/UNESP, Brazil. Population: 27,387 delivering women and 27,827 offspring. Data collection: maternal and perinatal data between 1995 and 2006 at the major level III and level II hospitals in Botucatu, Brazil following initiation of a safe motherhood education and referral system. Main outcome measures: Yearly rates of C-sections, maternal (/100,000 LB and perinatal (/1000 births mortality rates at both hospitals. Data analysis: Simple linear regression models were adjusted to estimate the referral system's annual effects on the total number of deliveries, C-section and perinatal mortality ratios in the two hospitals. The linear regression were assessed by residual analysis (Shapiro-Wilk test and the influence of possible conflicting observations was evaluated by a diagnostic test (Leverage, with p Results Over the time period evaluated, the overall C-section rate was 37.3%, there were 30 maternal deaths (maternal mortality ratio = 109.5/100,000 LB and 660 perinatal deaths (perinatal mortality rate = 23.7/1000 births. The C-section rate decreased from 46.5% to 23.4% at the level II hospital while remaining unchanged at the level III hospital. The perinatal mortality rate decreased from 9.71 to 1.66/1000 births and from 60.8 to 39.6/1000 births at the level II and level III hospital, respectively. Maternal mortality ratios were 16.3/100,000 LB and 185.1/100,000 LB at the level II and level III hospitals. There was a shift from direct to indirect causes of

    Full Text Available "nLipoproteins (LPs, the endogenous lipid-protein micro- and nanostructures involved in lipid metabolism, have attracted a high degree of interest in recent years for being used as novel drug delivery systems. Numerous diagnostic and therapeutic agents (in particular anti-cancer agents have been studied using native and (semisynthetic LPs as both prolonged and targeted drug delivery systems. Since all reported loading methods are basically in vitro or ex vivo procedures with related limitations, an idea has been raised for finding a completely new loading paradigm to overcome the limitations in using native particles as drug vehicles. The basis for this hypothesis is that we are able to load native and circulating LPs without extracting them from body via using specific monoclonal antibodies (MAb, already linked to desired drugs or to be linked to drug via proper linker system such as avidin-biotin bridges actively-targeted against specialized Apos available on the surface of all LPs. Obviously, by choosing the right anti-Apo antibody (preferably single chain variable fragment; scFv, we can select the right circulating LP subpopulation (i.e., LDL, HDL, VLDL, or CM. By considering all parameters and using the most appropriate strategy, this novel, safe, versatile, industrializable, and clinically translation-prone  paradigm could be used for both prolonged and (LP receptor- and non-LP receptor- targeted drug delivery purposes.

  13. Building confidence in decommissioning in France: Towards a safe, industrially applicable, coherent national system without site or waste liberation

    International Nuclear Information System (INIS)

    The rate of decommissioning in France is accelerating, as the first generation of power reactors will be actively decommissioned in the next few years. Experience has been gathered from past decommissioning activities and some current pilot decommissioning operations. This experience has shown that a national system has to be put in place to deal with decommissioning, waste elimination and site cleaning up activities in order to allow a consistent, safe, transparent and industrially applicable management of these matters. A system founded on successive lines of defence has been put into enforcement, which does not involve any site nor waste liberation, as it is considered that the criteria associated are always prone to discussion and contradiction. This system is based on the following concepts : 'nuclear waste', waste prone to have been contaminated or activated, is segregated from 'conventional waste' using a system involving successive lines of defence, and hence, building a very high level of confidence that no 'nuclear waste' will be eliminated without control in conventional waste eliminators or recycling facilities ; 'nuclear waste' is eliminated in dedicated facilities or repositories, or in conventional facilities under the condition of a special authorisation based on a radiological impact study and a public inquiry ; a global safety evaluation of the nuclear site is conducted after decommissioning in order to define possible use restrictions. In all cases, minimum restrictions will be put into enforcement in urbanisation plans to ensure sufficient precaution when planning future uses of the ground or the building. This paper describes this global system in detail and shows that its inherent consistency allows it to be easily applicable by operators while achieving a high level of safety and confidence.

  14. Application of Reactor Physics Calculation Methods to Criticality Control of Non-Inherently Safe Systems in Fuel Processing Plants

    International Nuclear Information System (INIS)

    The economics of fuel processing operations involving the handling of large quantities of fissionable materials can be significantly improved by utilizing somewhat detailed reactor physics calculation methods to establish criticality safe process parameters. These calculation techniques serve as an extension of critical experiment data to systems not specifically covered by such data and may be used to establish the safety of larger mass limits and process equipment dimensions than could be justified by conservative extrapolation of the available experimental data. This paper describes some of the calculation techniques used for this purpose at United Nuclear Corporation. Both hand calculation techniques and computerized techniques are discussed in connection with highly enriched uranium alloy water systems, poison-wrapped cylinders, fixed poison sheets in unsafe geometry tanks, and safety arrays of unmoderated uranium materials; and generally useful data obtained with these methods are presented. Comparison of these calculation methods against experimental data, and the assumptions made in applying these methods to criticality safety work, are also discussed. (author)

    Full Text Available The study of presidential cabinets has mainly focused on coalitional formations, distinguishing individual ministers in terms of their party affiliation particularly at cabinet instauration and termination. This article moves the focus to single-party cabinets to study minister appointment in situations where the legislative support is less relevant. A model of analysis that observes extra-partisan affiliations, individual technical skills and personal liaison with the president is proposed and exploratory applied to the Argentinean case. The results suggest that well positioned presidents tend to apply closer strategies of portfolio distribution, with levels of institutionalization that depends on the president’s party organization and the president’s style of leadership.

  17. SafeLand guidelines for landslide monitoring and early warning systems in Europe - Design and required technology

    Science.gov (United States)

    Bazin, S.

    2012-04-01

    Landslide monitoring means the comparison of landslide characteristics like areal extent, speed of movement, surface topography and soil humidity from different periods in order to assess landslide activity. An ultimate "universal" methodology for this purpose does not exist; every technology has its own advantages and disadvantages. End-users should carefully consider each one to select the methodologies that represent the best compromise between pros and cons, and are best suited for their needs. Besides monitoring technology, there are many factors governing the choice of an Early Warning System (EWS). A people-centred EWS necessarily comprises five key elements: (1) knowledge of the risks; (2) identification, monitoring, analysis and forecasting of the hazards; (3) operational centre; (4) communication or dissemination of alerts and warnings; and (5) local capabilities to respond to the warnings received. The expression "end-to-end warning system" is also used to emphasize that EWSs need to span all steps from hazard detection through to community response. The aim of the present work is to provide guidelines for establishing the different components for landslide EWSs. One of the main deliverables of the EC-FP7 SafeLand project addresses the technical and practical issues related to monitoring and early warning for landslides, and identifies the best technologies available in the context of both hazard assessment and design of EWSs. This deliverable targets the end-users and aims to facilitate the decision process by providing guidelines. For the purpose of sharing the globally accumulated expertise, a screening study was done on 14 EWSs from 8 different countries. On these bases, the report presents a synoptic view of existing monitoring methodologies and early-warning strategies and their applicability for different landslide types, scales and risk management steps. Several comprehensive checklists and toolboxes are also included to support informed

  18. Nuclear Materials Management in Relation to Safety and Criticality Control: A Study of Non-Inherently Safe Systems

    International Nuclear Information System (INIS)

    The production, utilization and handling of certain fissionable materials are associated with a particular type of danger, the risk of criticality. The engineer must try to avoid this risk, at the least possible expense, without hindering too much the work of production or conversion. Roughly speaking, there are three ways of eliminating this risk: limitation of solution concentrations, limitation of mass, and judicious choice of geometries. The tendency is to employ the third method as much as possible, i.e. to operate with inherently safe systems. Nevertheless, non-inherently safe systems are still common in nuclear installations and recourse sometimes has to be had to the first or second procedure. These methods are bound up with nuclear materials management. In installations where small quantities of fissionable materials are handled it is often possible to ensure nuclear safety if the mass of fissionable material permitted in each room is less than the minimum critical mass. In larger installations this type of control, based entirely on materials management, becomes impossible. The paper considers the relation between management and nuclear safety in the special case of a plant for the aqueous processing of irradiated fuels (the fuels are based on natural uranium). From the point of view of criticality control such a plant comprises, broadly speaking, three sections: In the first section, where fairly dilute solutions are treated, the type of control required is that over concentration. This control (based on analysis and the use of neutron counters) is easy to carry out but it is difficult to ensure that no deposits are formed. Although experience has shown that there is no particular reason for fearing such deposits, the existence of a deficit in the material balance gives rise to apprehension in respect of criticality. In this section, materials management, still imperfectly carried out, is of prime importance for safety. The second section is where

    Hydrocarbon refrigerators are now on sale in European countries. However, hydrocarbons are flammable. A common claim is that concentration of hydrocarbon in the refrigerator could exceed the lower explosive limit by a sudden leak and then a spark ignites a flame causing overpressure. There is the need of the studies on potential risks originated from the use of flammable refrigerants. Thus, the flow rate of the fresh air into the refrigerator cabinet has been defined experimentally, and the spatial average concentration in the refrigerator cabinet has been analyzed theoretically to predict the dangerous time in excess of the lower explosive limit.

  20. Hygienic features of working conditions prevailing in X-ray cabinets

    International Nuclear Information System (INIS)

    The results of an investigation of 352 x-ray cabinets showed that their personnel is subjected to simultaneous action of a number of factors: discomfortable microclimate, small concentrations of ozone and nitrogen oxides (within 0.1 of the maximum permissible concentration). The hands of the personnel, especially those of the x-ray laboratory assistants are contaminated with lead (2.38mg in the hands washings). Therefore the assessment of labour conditions prevailing in an x-ray cabinet and the accomplishment of measures of their provement should be carried out with due regards to all the complex of the above mentioned factors besides the ionizing radiation

    2016-04-01

    To keep the Earth System in a desirable region of its state space, such as defined by the recently suggested "tolerable environment and development window", "guardrails", "planetary boundaries", or "safe (and just) operating space for humanity", one not only needs to understand the quantitative internal dynamics of the system and the available options for influencing it (management), but also the structure of the system's state space with regard to certain qualitative differences. Important questions are: Which state space regions can be reached from which others with or without leaving the desirable region? Which regions are in a variety of senses "safe" to stay in when management options might break away, and which qualitative decision problems may occur as a consequence of this topological structure? In this work, we develop a mathematical theory of the qualitative topology of the state space of a dynamical system with management options and desirable states, as a complement to the existing literature on optimal control which is more focussed on quantitative optimization and is much applied in both the engineering and the integrated assessment literature. We suggest a certain terminology for the various resulting regions of the state space and perform a detailed formal classification of the possible states with respect to the possibility of avoiding or leaving the undesired region. Our results indicate that before performing some form of quantitative optimization such as of indicators of human well-being for achieving certain sustainable development goals, a sustainable and resilient management of the Earth System may require decisions of a more discrete type that come in the form of several dilemmas, e.g., choosing between eventual safety and uninterrupted desirability, or between uninterrupted safety and larger flexibility. We illustrate the concepts and dilemmas drawing on conceptual models from climate science, ecology, coevolutionary Earth System modeling

    Due to the practical problems of the high costs and the long development cycle of China’s cabinet production,a computer-aided design method of the cabinet based on style imagery is proposed.According to the principle of the conjoint analysis method, the rough set theory and the weight coefficient of different components of the cabinet,a multi-dimensional model of style imagery to evaluate the cabinet is built. Then the related constants of style imagery are calculated and the cabinet components library is also built by the three-dimensional modeling.Finally,with recombinant technology and the mapping model between cabinet style and external characteristics,the prototype system based on Visual Studio is proposed.This system actualizes the bidirectional reasoning between product style imagery and the shape features,which can assist designers to produce more creative designs,greatly improve the efficiency of cabinet development and increase the profits of companies.%针对国内机柜产品成本高和开发周期长的实际问题,提出了一种基于风格意象的机柜计算机辅助设计方法。根据联合分析法原理、粗糙集理论以及机柜各组成部件的权重系数,建立了机柜风格意象评价的多维模型。计算得到了各风格意象的相关常量及系数,并通过3D 模型建立了机柜组件库。最终,结合组件重组技术以及机柜产品风格与特征之间的映射模型,基于 Visual Studio 软件开发了原型系统。该系统实现了产品风格意象与造型特征的双向推理,辅助设计师进行创新设计,大大提高了机柜研发的效率,提升了企业的经济效益。

    Energy Technology Data Exchange (ETDEWEB)

    1995-12-31

    Most designers are not schooled in the area of human-interaction psychology and therefore tend to rely on the traditional ergonomic aspects of human factors when designing complex human-interactive workstations related to reactor operations. They do not take into account the differences in user information processing behavior and how these behaviors may affect individual and team performance when accessing visual displays or utilizing system models in process and control room areas. Unfortunately, by ignoring the importance of the integration of the user interface at the information process level, the result can be sub-optimization and inherently error- and failure-prone systems. Therefore, to minimize or eliminate failures in human-interactive systems, it is essential that the designers understand how each user`s processing characteristics affects how the user gathers information, and how the user communicates the information to the designer and other users. A different type of approach in achieving this understanding is Neuro Linguistic Programming (NLP). The material presented in this paper is based on two studies involving the design of visual displays, NLP, and the user`s perspective model of a reactor system. The studies involve the methodology known as NLP, and its use in expanding design choices from the user`s ``model of the world,`` in the areas of virtual reality, workstation design, team structure, decision and learning style patterns, safety operations, pattern recognition, and much, much more.

  2. Insite or Outside the Law: Examining the Place of Safe Injection Sites within the Canadian Legal System

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available In response to the mounting number of HIV/AIDS and overdose deaths directly attributable to intravenous drug use during the 1980 and 1990’s, governments across the world began considering alternatives to traditional prohibitionist drug policies. These alternatives, generally described as harm reduction strategies involving needle exchange programs and safe injection sites, rapidly gained acceptance across Europe. By contrast, they encountered significant opposition in North America. This thesis summarily traces the history of Canadian drug law, describing the development and impact of the harm reduction movement in Canada and the establishment of the first and only safe injection site (SIS in North America (Insite. Employing a repressive formalist analysis of the application of federal drug laws, I then examine the role of the current Conservative government in contesting harm reduction strategies and refusing full legalization of Insite. I illustrate that through the strategic manipulation and discriminatory enforcement of drug laws and political gamesmanship relating to the criteria grounding Insite’s exemption from current drug laws, the government has failed to fulfill a set of fundamental social values with respect to Insite’s users and members of the downtown eastside of Vancouver. Interviews with injection drug users, workers at Insite and residents of the local community provide empirical support for the beneficial effects of safe injection sites, and expose the politics of the struggle for Insite’s continued existence. I also show how the Conservative anti-drug ideologues have led a resistance against classifying drug addiction as a health-related rather than criminal problem, despite significant scientific evidence to the contrary, and how this resistance has resulted in the further marginalization of injection drug users.

  3. Safe and High Quality Food Production using Low Quality Waters and Improved Irrigation Systems and Management (SAFIR)

    The safe use of treated domestic wastewater for irrigation needs to address the risks for humans (workers, exposed via contact with irrigation water, soil, crops and food, consumers, exposed via ingestion of fresh and processed food), for animals (via ingestion of crops an soil), for the crops and agricultural productivity (via salinity and trace element uptake), for soil (via accumulation or release of pollutants) as well as for surface, groundwaters and the associated ecosystems (via runoff and infiltration, Kass et al., 2005, Bouwer, 2000). A work package in the EU FP5 project SAFIR is dedicated to study the impact of wastewater irrigation on the soil-water-plant-product system. Its monitoring program comprises pathogens and inorganic pollutants, including both geogenic and potentially anthropogenic trace elements in the aim to better understand soil-irrigation water interactions. The SAFIR field study sites are found in China, Italy, Crete, and Serbia. A performance evaluation of SAFIR-specific treatment technology through the monitoring of waste water and irrigation water quality was made through waste water chemical and microbiological qualities, which were investigated upstream and downstream of the SAFIR specific treatment three times per season. Irrigation water transits through the uppermost soil decimetres to the crop roots. The latter will become, in the course of the irrigation season, the major sink of percolating water, together with evaporation. The water saving irrigation techniques used in SAFIR are surface and subsurface drip irrigation. The investigation of the solid soil phase concentrates on the root zone as main transit and storage compartment for pollutants and, eventually, pathogens. The initial soil quality was assessed through a sampling campaign before the onset of the first year irrigation; the soil quality has been monitored throughout three years under cultivation of tomatoes or potatoes.

  4. Computation of sound radiation by a driver in a cabinet using a substitute source approach.

    Lindberg, Anders; Pavić, Goran

    2015-08-01

    Sound radiation by a driver set in a rigid closed cabinet is modeled analytically using the principle of wave superposition. The driver-cabinet assembly is replaced by an array of volumeless substitute sources-monopoles-confined within its surface. The role of substitute sources is to reproduce the sound field exterior to the surface as close to the original field as possible. The frequency dependent positions and strengths of substitute monopoles are optimized by an iterative search procedure aimed at matching the prescribed surface boundary conditions of the original source. The time-consuming optimization of monopole positions is carried out at narrowband center frequencies reducing the computational cost without significant loss of accuracy. The consistency of computed results is verified by checking the power output through the cabinet surface. Modeling is done for anechoic and semi-anechoic conditions. The model has been validated experimentally in a semi-anechoic room with satisfactory results using a mid-range driver set in a closed-box baffle. PMID:26328727

  6. MAAP comparisons to SAFE

    International Nuclear Information System (INIS)

    General Electric provided results for several boiling water reactor/4 (BWR/4) accident sequences using the SAFE computer code. MAAP-BWR 3.0B Revision 6, was exercised for the same sequences to compare against the SAFE results. Overall, the SAFE and MAAP results for the sequences analyzed show excellent agreement. There are some uncertainties as to the assumptions in the SAFE calculations and the initial conditions. However, given those uncertainties, MAAP and SAFE appear to agree quite well on the response of the reactor vessel for various accident sequences

  7. Type Safe Extensible Programming

    2009-10-01

    Software products evolve over time. Sometimes they evolve by adding new features, and sometimes by either fixing bugs or replacing outdated implementations with new ones. When software engineers fail to anticipate such evolution during development, they will eventually be forced to re-architect or re-build from scratch. Therefore, it has been common practice to prepare for changes so that software products are extensible over their lifetimes. However, making software extensible is challenging because it is difficult to anticipate successive changes and to provide adequate abstraction mechanisms over potential changes. Such extensibility mechanisms, furthermore, should not compromise any existing functionality during extension. Software engineers would benefit from a tool that provides a way to add extensions in a reliable way. It is natural to expect programming languages to serve this role. Extensible programming is one effort to address these issues. In this thesis, we present type safe extensible programming using the MLPolyR language. MLPolyR is an ML-like functional language whose type system provides type-safe extensibility mechanisms at several levels. After presenting the language, we will show how these extensibility mechanisms can be put to good use in the context of product line engineering. Product line engineering is an emerging software engineering paradigm that aims to manage variations, which originate from successive changes in software.

  10. OPINION: Safe exponential manufacturing

    Science.gov (United States)

    Phoenix, Chris; Drexler, Eric

    2004-08-01

    In 1959, Richard Feynman pointed out that nanometre-scale machines could be built and operated, and that the precision inherent in molecular construction would make it easy to build multiple identical copies. This raised the possibility of exponential manufacturing, in which production systems could rapidly and cheaply increase their productive capacity, which in turn suggested the possibility of destructive runaway self-replication. Early proposals for artificial nanomachinery focused on small self-replicating machines, discussing their potential productivity and their potential destructiveness if abused. In the light of controversy regarding scenarios based on runaway replication (so-called 'grey goo'), a review of current thinking regarding nanotechnology-based manufacturing is in order. Nanotechnology-based fabrication can be thoroughly non-biological and inherently safe: such systems need have no ability to move about, use natural resources, or undergo incremental mutation. Moreover, self-replication is unnecessary: the development and use of highly productive systems of nanomachinery (nanofactories) need not involve the construction of autonomous self-replicating nanomachines. Accordingly, the construction of anything resembling a dangerous self-replicating nanomachine can and should be prohibited. Although advanced nanotechnologies could (with great difficulty and little incentive) be used to build such devices, other concerns present greater problems. Since weapon systems will be both easier to build and more likely to draw investment, the potential for dangerous systems is best considered in the context of military competition and arms control.

  11. Development of Modern Safe Systems of Work at the Imperial College Reactor Centre and Their Application to Neutron Detector Testing and Nuclear Training Courses

    International Nuclear Information System (INIS)

    The CONSORT design reactor is owned by, and licensed to, Imperial College of Science, Technology and Medicine, and has been in continuous safe operation since 1965. Today, it is the only civil research reactor left in the United Kingdom. CONSORT is designated a low power research reactor and is rated at 100 kW. The paper concentrates on the issues that have been addressed in ensuring that worker doses are maintained as low as reasonably practicable (ALARP), and describes how robust systems have been implemented to ensure that all assessments are in line with this principle. The principles of risk assessment are applied to all operations within the reactor centre and the framework leading to the establishment of the safe system of work will be outlined and discussed. Two case studies are described in detail as examples, showing the importance to the industry of ensuring that a system is in place to allow the work to continue and summarizes the experience gained in the past few years at Imperial College Reactor Centre. These experiences will provide useful information that managers of similar facilities may wish to consider in formulating their own arrangements. The CONSORT reactor provides an open beam tube facility for the calibration and periodic testing of neutron flux detectors (primarily fission chambers and ion chambers). The first case study outlines the detector testing programme that takes place on the CONSORT reactor using this facility. The second case study relates to the use of this integrated approach to safety management in the teaching environment. With ''safe systems of work'' in place, it is now possible to reinstate the popular student experiment of directly viewing the Cerenkov radiation emitted from the critical CONSORT reactor core. This particular activity had been discontinued for some years on ALARP grounds. (author)

    2010-10-15

    In this paper, the model for the multi-deck medium temperature display cabinets is developed with the integration of CFD and cooling coil sub-models. The distributed method is used to develop the cooling coil model with the airside inputs from the outputs of the CFD model. Inversely, the airside outputs from the cooling coil model are used to update the boundary conditions of the CFD model. To validate this cabinet model, a multi-deck medium temperature display cabinet refrigerated with a secondary refrigerant cooling coil was selected as a prototype and mounted in an air conditioned chamber. Extensive tests were conducted at constant space air temperature and varied relative humilities. The cabinet model has been validated by comparing with the test results for the parameters of air at different locations of the flow path, and temperatures of refrigerant and food product, etc. The validated model is therefore used to explore and analyse the cabinet performance and control strategies at various operating and design conditions.

  20. Inherently safe light water reactors

    International Nuclear Information System (INIS)

    Today's large nuclear power reactors of world-wise use have been designed based on the philosophy. It seems that recent less electricity demand rates, higher capital cost and the TMI accident let us acknowledge relative small and simplified nuclear plants with safer features, and that Chernobyl accident in 1983 underlines the needs of intrinsic and passive safety characteristics. In such background, several inherently safe reactor concepts have been presented abroad and domestically. First describing 'Can inherently safe reactors be designed,' then I introduce representative reactor concepts of inherently safe LWRs advocated abroad so far. All of these innovative reactors employ intrinsic and passive features in their design, as follows: (1) PIUS, an acronym for Process Inherent Ultimate Safety, or an integral PWR with passive heat sink and passive shutdown mechanism, advocated by ASEA-ATOM of Sweden. (2) MAP(Minimum Attention Plant), or a self-pressurized, natural circulation integral PWR, promoted by CE Inc. of the U.S. (3) TPS(TRIGA Power System), or a compact PWR with passive heat sink and inherent fuel characteristics of large prompt temperature coefficient, prompted by GA Technologies Inc. of the U.S. (4) PIUS-BWR, or an inherently safe BWR employing passively actuated fluid valves, in competition with PIUS, prompted by ORNL of the U.S. Then, I will describe the domestic trends in Japan and the innovative inherently safe LWRs presented domestically so far.

  4. A Mobile Information System Based on Crowd-Sensed and Official Crime Data for Finding Safe Routes: A Case Study of Mexico City

    Directory of Open Access Journals (Sweden)

    Félix Mata

    2016-01-01

    Full Text Available Mobile information systems agendas are increasingly becoming an essential part of human life and they play an important role in several daily activities. These have been developed for different contexts such as public facilities in smart cities, health care, traffic congestions, e-commerce, financial security, user-generated content, and crowdsourcing. In GIScience, problems related to routing systems have been deeply explored by using several techniques, but they are not focused on security or crime rates. In this paper, an approach to provide estimations defined by crime rates for generating safe routes in mobile devices is proposed. It consists of integrating crowd-sensed and official crime data with a mobile application. Thus, data are semantically processed by an ontology and classified by the Bayes algorithm. A geospatial repository was used to store tweets related to crime events of Mexico City and official reports that were geocoded for obtaining safe routes. A forecast related to crime events that can occur in a certain place with the collected information was performed. The novelty is a hybrid approach based on semantic processing to retrieve relevant data from unstructured data sources and a classifier algorithm to collect relevant crime data from official government reports with a mobile application.

  5. MMW radar enhanced vision systems: the Helicopter Autonomous Landing System (HALS) and Radar-Enhanced Vision System (REVS) are rotary and fixed wing enhanced flight vision systems that enable safe flight operations in degraded visual environments

    Cross, Jack; Schneider, John; Cariani, Pete

    2013-05-01

    Sierra Nevada Corporation (SNC) has developed rotary and fixed wing millimeter wave radar enhanced vision systems. The Helicopter Autonomous Landing System (HALS) is a rotary-wing enhanced vision system that enables multi-ship landing, takeoff, and enroute flight in Degraded Visual Environments (DVE). HALS has been successfully flight tested in a variety of scenarios, from brown-out DVE landings, to enroute flight over mountainous terrain, to wire/cable detection during low-level flight. The Radar Enhanced Vision Systems (REVS) is a fixed-wing Enhanced Flight Vision System (EFVS) undergoing prototype development testing. Both systems are based on a fast-scanning, threedimensional 94 GHz radar that produces real-time terrain and obstacle imagery. The radar imagery is fused with synthetic imagery of the surrounding terrain to form a long-range, wide field-of-view display. A symbology overlay is added to provide aircraft state information and, for HALS, approach and landing command guidance cuing. The combination of see-through imagery and symbology provides the key information a pilot needs to perform safe flight operations in DVE conditions. This paper discusses the HALS and REVS systems and technology, presents imagery, and summarizes the recent flight test results.

  7. Experimental analysis of the thermal entrainment factor of air curtains in vertical open display cabinets for different ambient air conditions

    International Nuclear Information System (INIS)

    The vertical open refrigerated display cabinets suffer alterations of their thermal performance and energy efficiency due to variations of ambient air conditions. The air curtain provides an aerothermodynamics insulation effect that can be evaluated by the thermal entrainment factor calculation as an engineering approximation or by the calculus of all sensible and latent thermal loads. This study presents the variation of heat transfer rate and thermal entrainment factor obtained through experimental tests carried out for different ambient air conditions, varying air temperature, relative humidity, velocity and its direction relatively to the display cabinet frontal opening. The thermal entrainment factor are analysed and compared with the total sensible and latent heats results for the experimental tests. From an engineering point of view, it is concluded that thermal entrainment factor cannot be used indiscriminately, although its use is suitable to design better cabinet under the same climate class condition.

    The adequate use of EV in the Iberian system could allow the integration of more renewable power sources, like wind generation, while maintaining the operational risk indices within adequate values. For this purpose monitoring systems and smart charging strategies should be standardized and economic incentives should be created in order to foster the participation of EV owners in helping system operation by providing reserve services. If EV can be considered as secondary reserve providers, one can also integrate further wind generation without requiring an increase of conventional generation reserves. (orig.)

Some modifications are introduced in order to perform parametric studies dealing with low-cost geometrical and functional characteristics for improvement of the global performance and energy efficiency. The parametric studies are devoted to the analysis of the thermal response and behaviour inside the food conservation space influenced by (1 air flow rate through the evaporator heat exchanger; (2 air curtain behaviour; (3 hole dimensions and distribution of the back panel; (4 discharge and return grilles angles; and (5 flow deflectors inside the internal duct. The analysis of the numerical predictions from the parametric studies allows the development of an optimized model for the conception of an open refrigerated display cabinet with a more adequate configuration. The numerical predictions of the optimized model show lower product temperature and reduced electrical energy consumption, allowing the improvement of the food safety and the energy rationalization of the refrigeration equipment.

  18. A system to test the ground surface conditions of construction sites--for safe and efficient work without physical strain.

    Science.gov (United States)

    Koningsveld, Ernst; van der Grinten, Maarten; van der Molen, Henk; Krause, Frank

    2005-07-01

    Ground surface conditions on construction sites have an important influence on the health and safety of workers and their productivity. The development of an expert-based "working conditions evaluation" system is described, intended to assist site managers in recognising unsatisfactory ground conditions and remedying these. The system was evaluated in the period 2002-2003. The evaluation shows that companies recognize poor soil/ground conditions as problematic, but are not aware of the specific physical workload hazards. The developed methods allow assessment of the ground surface quality and selection of appropriate measures for improvement. However, barriers exist at present to wide implementation of the system across the industry. Most significant of these is that responsibility for a site's condition is not clearly located within contracting arrangements, nor is it a topic of serious negotiation. PMID:15892938

  20. Asymptotically Safe Dark Matter

    CERN Document Server

    Sannino, Francesco

    2014-01-01

    We introduce a new paradigm for dark matter interactions according to which the interaction strength is asymptotically safe. In models of this type, the interaction strength is small at low energies but increases at higher energies towards a finite constant value of the coupling. The net effect is to partially offset direct detection constraints without affecting thermal freeze-out at higher energies. High-energy collider and indirect annihilation searches are the primary ways to constrain or discover asymptotically safe dark matter.

  1. An art report to analyze internal and external research status for the establishment of the safe supply system of the foods for military meal service using ionization energy

    International Nuclear Information System (INIS)

    Since the risk of food-borne pathogenic diseases such as E. coli O157:H7 and Salmonella always remains in the military meal service system, it is necessary to develop the method to eliminate this problem. According to the preference survey of military meals, it is shown that soldiers preferred the improvement in quality such as tastes and variety to the increase in quantity. For this reason, the supply of diverse foods, improvement of cooking methods, and the complement of meal service facilities are required. The developed countries such as the United States maintain the facilities to control the environmental factors such as temperature, moisture, and oxygen and they develop and use the rapid methods to test the storage times of each category of foods based on the theoretical studies of food storage/preservation/processing and their experimental data. Due to the ordinary sanitation methods are gradually limited all over the world, as new technology for prevention of food-borne diseases and establishment to manufacture wholesome food, a radiation technology is very effective to ensure safe food and preservation/distribution, improve the safety of processed food and its manufacturing processes. And, the military meal service including combat rations furnishes viability, energy, ability for duty, and mental rest to soldiers. Furthermore, it ensures combat capabilities, enhances mobility power of troops, improves combat efficiency, and establishes the military supply system. It is necessary to study irradiation technique in order to establish the safe food supply system for military meal service and eliminate contamination such as food-borne disease for combat crews as an essential element in military power

  2. SAFE/SNAP application to shipboard security

    International Nuclear Information System (INIS)

    An application of the combined Safeguards Automated Facility Evaluation/Safeguards Network Analysis Procedure (SAFE/SNAP) modeling technique to a physical protection system (PPS) aboard a generic ship is described. This application was performed as an example of how the SAFE and SNAP techniques could be used. Estimates of probability of interruption and neutralization for the example shipboard PPS are provided by SAFE as well as an adversary scenario, which serves as input to SNAP. This adversary scenario is analyzed by SNAP through four cases which incorporate increasingly detailed security force tactics. Comparisons between the results of the SAFE and SNAP analyses are made and conclusions drawn on the validity of each technique. Feedback from SNAP to SAFE is described, and recommendations for upgrading the ship based on the results of the SAFE/SNAP application are also discussed

  3. Aqueous two-phase systems: an efficient, environmentally safe and economically viable method for purification of natural dye carmine.

    2009-11-01

    Partition of the natural dye carmine has been studied in aqueous two-phase systems prepared by mixing aqueous solutions of polymer or copolymer with aqueous salt solutions (Na(2)SO(4) and Li(2)SO(4)). The carmine dye partition coefficient was investigated as a function of system pH, polymer molar mass, hydrophobicity, system tie-line length and nature of the electrolyte. It has been observed that the carmine partition coefficient is highly dependent on the electrolyte nature and pH of the system, reaching values as high as 300, indicating the high potential of the two-phase extraction with ATPS in the purification of carmine dye. The partition relative order was Li(2)SO(4)"Na(2)SO(4). Carmine molecules were concentrated in the polymer-rich phase, indicating an enthalpic specific interaction between carmine and the pseudopolycation, which is formed by cation adsorption along the macromolecule chain. When the enthalpic carmine-pseudopolycation interaction decreases, entropic forces dominate the natural dye-transfer process, and the carmine partitioning coefficient decreases. The optimization of the extraction process was obtained by a central composite face-centered (CCF) design. The CCF design was used to evaluate the influence of Li(2)SO(4) and PEO 1500 concentration and of the pH on the partition coefficient of carmine. The conditions that maximize the partition of carmine into the top phase were determined to be high concentrations of PEO and Li(2)SO(4) and low pH values within the ranges studied. PMID:19800067

  5. A Safe, Self-Calibrating, Wireless System for Measuring Volume of Any Fuel at Non-Horizontal Orientation

    Science.gov (United States)

    Woodward, Stanley E.; Taylor, Bryant D.

    2010-01-01

    A system for wirelessly measuring the volume of fluid in tanks at non-horizontal orientation is predicated upon two technologies developed at Langley Research Center. The first is a magnetic field response recorder that powers and interrogates magnetic field response sensors [ Magnetic Field Response Measurement Acquisition System, (LAR-16908), NASA Tech Briefs, Vol. 30, No. 6 (June 2006), page 28]. Magnetic field response sensors are a class of sensors that are powered via oscillating magnetic fields and when electrically active respond with their own magnetic fields whose attributes are dependent upon the magnitude of the physical quantity being measured. The response recorder facilitates the use of the second technology, which is a magnetic field response fluid-level sensor ["Wireless Fluid- Level Sensors for Harsh Environments," (LAR-17155), NASA Tech Briefs, Vol. 33, No. 4 (April 2009), page 30]. The method for powering and interrogating the sensors allows them to be completely encased in materials (Fig. 1) that are chemically resilient to the fluid being measured, thereby facilitating measurement of substances (e.g., acids, petroleum, cryogenic, caustic, and the like) that would normally destroy electronic circuitry. When the sensors are encapsulated, no fluid (or fluid vapor) is exposed to any electrical component of the measurement system. There is no direct electrical line from the vehicle or plant power into a fuel container. The means of interrogating and powering the sensors can be completely physically and electrically isolated from the fuel and vapors by placing the sensor on the other side of an electrically non-conductive bulkhead (Fig. 2). These features prevent the interrogation system and its electrical components from becoming an ignition source.

  6. Prevention of postoperative atrial fibrillation: novel and safe strategy based on the modulation of the antioxidant system

    Directory of Open Access Journals (Sweden)

    Ramón eRodrigo

    2012-04-01

    Full Text Available Postoperative atrial fibrillation (AF is the most common arrhythmia following cardiac surgery with extracorporeal circulation. The pathogenesis of postoperative AF is multifactorial. Oxidative stress, caused by the unavoidable ischemia-reperfusion event occurring in this setting, is a major contributory factor. ROS-derived effects could result in lipid peroxidation, protein carbonylation or DNA oxidation of cardiac tissue, thus leading to functional and structural myocardial remodeling. The vulnerability of myocardial tissue to the oxidative challenge is also dependent on the activity of the antioxidant system. High ROS levels, overwhelming this system, should result in deleterious cellular effects, such as the induction of necrosis, apoptosis or autophagy. Nevertheless, tissue exposure to low to moderate ROS levels could trigger a survival response with a trend to reinforce the antioxidant defense system. Administration of n-3 polyunsaturated fatty acids (PUFA, known to involve a moderate ROS production, is consistent with a diminished vulnerability to the development of postoperative AF. Accordingly, supplementation of n-3 PUFA successfully reduced the incidence of postoperative AF after coronary bypass grafting. This response is due to an up-regulation of antioxidant enzymes, as shown in experimental models. In turn, non-enzymatic antioxidant reinforcement through vitamin C administration prior to cardiac surgery has also reduced the postoperative AF incidence. Therefore, it should be expected that a mixed therapy result in an improvement of the cardioprotective effect by modulating both components of the antioxidant system. We present available evidence supporting the view of an effective prevention of postoperative AF including a 2-step therapeutic strategy: n-3 PUFA followed by vitamin C supplementation to patients scheduled for cardiac surgery with extracorporeal circulation. The present study should encourage the design of clinical

  7. An intrinsically safe facility for forefront research and training on nuclear technologies — General description of the system

    Science.gov (United States)

    Mansani, L.; Bruzzone, M.; Frambati, S.; Reale, M.

    2014-04-01

    In the framework of research on generation-IV reactors, it is very important to have infrastructures specifically dedicated to the study of fundamental parameters in dynamics and kinetics of future fast-neutron reactors. Among various options pursued by international groups, Italy focused on lead-cooled reactors, which guarantee minimal neutron slowdown and capture and efficient cooling. In this paper it is described the design of a the low-power prototype generator, LEADS, that could be used within research facilities such as the National Laboratory of Legnaro of the INFN. The LEADS has a high safety standard in order to be used as a training facility, but it has also a good flexibility so as to allow a wide range of measurements and experiments. A high safety standard is achieved by limiting the reactor power to less than few hundred kW and the neutron multiplication factor k eff to less than 0.95 (a limiting value for spent fuel pool), by using a pure-uranium fuel (no plutonium) and by using solid lead as a diffuser. The proposed core is therefore intrinsically subcritical and has to be driven by an external neutron source generated by a proton beam impinging in a target. Preliminary simulations, performed with the MCNPX code indicated, for a 0.75mA continuous proton beam current at 70MeV proton energy, a reactor power of about 190kW when using a beryllium converter. The enriched-uranium fuel elements are immersed in a solid-lead matrix and contained within a steel vessel. The system is cooled by helium gas, which is transparent to neutrons and does not undergo activation. The gas is pumped by a compressor through specific holes at the entrance of the active volume with a temperature which varies according to the operating conditions and a pressure of about 1.1MPa. The hot gas coming out of the vessel is cooled by an external helium-water heat exchanger. The beryllium converter is cooled by its dedicated helium gas cooling system. After shutdown, the decay is

    2016-01-01

    Hepatitis B viral (HBV) infections represent major public health problem and are an occupational hazard for healthcare workers. Current alum-adjuvanted HBV vaccine is the most effective measure to prevent HBV infection. However, the vaccine has some limitations including poor response in some vaccinee and being a frost-sensitive suspension. The goal of our study was to use an alternative natural adjuvant system strongly immunogenic allowing for a reduction in dose and cost. We tested HBV surface antigen (HBsAg) adjuvanted with chitosan (Ch) and sodium alginate (S), both natural adjuvants, either alone or combined with alum in mouse model. Mice groups were immunized subcutaneously with HBsAg adjuvanted with Ch or S, or triple adjuvant formula with alum (Al), Ch, and S, or double formulations with AlCh or AlS. These were compared to control groups immunized with current vaccine formula or unadjuvanted HBsAg. We evaluated the rate of seroconversion, serum HBsAg antibody, IL-4, and IFN-γ levels. The results showed that the solution formula with Ch or S exhibited comparable immunogenic responses to Al-adjuvanted suspension. The AlChS gave significantly higher immunogenic response compared to controls. Collectively, our results indicated that Ch and S are effective HBV adjuvants offering natural alternatives, potentially reducing dose. PMID:27493674

  10. The use of beam propagation modeling of Beamlet and Nova to ensure a ''safe'' National Ignition Facility laser system design

    International Nuclear Information System (INIS)

    An exhaustive set of Beamlet and Nova laser system simulations were performed over a wide range of power levels in order to gain understanding about the statistical trends in Nova and Beamlet's experimental data sets, and to provide critical validation of propagation tools and design ''rules'' applied to the 192-arm National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL). The experiments considered for modeling were at 220-ps FWHM duration with unpumped booster slabs on Beamlet, and 100-ps FWHM with pumped 31.5-cm and 46-cm disk amplifiers on Nova. Simulations indicated that on Beamlet, the AB (the intensity pendent phase shift parameter characterizing the tendency towards beam filamentation) for the booster amplifier stage without pumping, would be nearly identical to the AB expected on NIF at the peak of a typical 20-ns long shaped pulse intended for ICF target irradiation. Therefore, with energies less than I kJ in short-pulses, we examined on Beamlet the comparable AB-driven filamentation conditions predicted for long ICF pulseshapes in the 18 kJ regime on the NIF, while avoiding fluence dependent surface damage. Various spatial filter pinhole configurations were examined on Nova and Beamlet. Open transport spatial filter pinholes were used in some experiments to allow the direct measurement of the onset of beam filamentation. Schlieren images on Beamlet of the far field irradiance measuring the scattered light fraction outside of 33-microradians were also obtained and compared to modeled results

    2015-01-01

    Full Text Available In recent years there has been a significant growth in voluntary certification schemes field in wine sector, by following a general trend that has characterised agricultural products and foodstuffs. The voluntary certification system is aimed at adding value to products, while differentiating it on the related market. The paper presents the preliminary results of a work-in-progress research on the voluntary certification schemes in the Italian wine sector. Through a case-study analysis, the paper is aimed at highlighting the emerging implementation issues. The scope of the case-studies is limited to three voluntary certification schemes, which underlie similarities with the organic wine farming and operate at business-to-consumer level. The paper is divided in three parts. Part I will examine the relevant legal framework on wine quality standards, by framing the legislation in mandatory, regulatory and voluntary. Part II will consider three case-studies of voluntary certification schemes that are implemented in the Italian wine sector. Part III will analyse the emerging issues that arise from the analysis of the case-studies. In conclusion, the paper highlights the key challenge, which concerns finding a trade-off between consumer protection and the promotion of free trade in an openly competitive market.

  12. The Safe Lambda Calculus

    CERN Document Server

    Blum, William

    2009-01-01

    Safety is a syntactic condition of higher-order grammars that constrains occurrences of variables in the production rules according to their type-theoretic order. In this paper, we introduce the safe lambda calculus, which is obtained by transposing (and generalizing) the safety condition to the setting of the simply-typed lambda calculus. In contrast to the original definition of safety, our calculus does not constrain types (to be homogeneous). We show that in the safe lambda calculus, there is no need to rename bound variables when performing substitution, as variable capture is guaranteed not to happen. We also propose an adequate notion of beta-reduction that preserves safety. In the same vein as Schwichtenberg's 1976 characterization of the simply-typed lambda calculus, we show that the numeric functions representable in the safe lambda calculus are exactly the multivariate polynomials; thus conditional is not definable. We also give a characterization of representable word functions. We then study the ...

    2009-09-15

    Different designs of flat-tube heat exchangers with plain fins have been evaluated theoretically in a parameter study in order to evaluate their performance potential in indirectly cooled display cabinets. Two different types of flat-tube heat exchangers were considered; one with serpentine fins and one with continuous plate fins. Both flat-tube heat exchanger types were adapted to the laminar flow regime on the liquid as well as on the air side. The performance of the two heat exchanger types had previously been verified experimentally under dehumidifying conditions. The results from this parameter study show that considerable savings in the required electric drive power to compressors, pumps and fans can be obtained in comparison with the traditional cooling coil. The savings may be up to 15%. In addition, the required temperature difference for the flat-tube heat exchangers is so small that frost-free operation is possible, which would result in even larger savings. (author)

    2012-08-01

    Full Text Available The United Kingdom’s security policy between 1997-2007, the time when Tony Blair���s Labour dominated the Cabinet, cannot be easily distinguished from the foreign policy. The two are strategically combined and are the responsibility of so many institutions that one finds it difficult to assess them. However, as the period is dominated by the 9/11 attacks and the military interventions in Afghanistan and Iraq, the British defense policy is unitarily centered on the threat of terrorism and weapons of mass destruction. Despite the many holders of decision-making power, it appears that the instruments to be used in achieving a state of comfort on a security level are mainly documents that are to become the basis of further action.

    The significant increase of skin cancer occurring in the western world is attributed to longer sun expose during leisure time. For prevention, people should become aware of the risks of UV light exposure by showing skin damage and the protective effect of sunscreen with an UV camera. An UV awareness imaging system optimized for 365 nm (UV-A) was develop using consumer components being interactive, safe and mobile. A Sony NEX5t camera was adapted to full spectral range. In addition, UV transparent lenses and filters were selected based on spectral characteristics measured (Schott S8612 and Hoya U-340 filters) to obtain the highest contrast for e.g. melanin spots and wrinkles on the skin. For uniform UV illumination, 2 facial tanner units were adapted with UV 365 nm black light fluorescent tubes. Safety of the UV illumination was determined relative to the sun and with absolute irradiance measurements at the working distance. A maximum exposure time over 15 minutes was calculate according the international safety standards. The UV camera was successfully demonstrated during the Dutch National Skin Cancer day and was well received by dermatologists and participating public. Especially, the 'black paint' effect putting sun screen on the face was dramatic and contributed to the awareness of regions on the face what are likely to be missed applying sunscreen. The UV imaging system shows to be promising for diagnostics and clinical studies in dermatology and potentially in other areas (dentistry and ophthalmology)

    The Center of Isotopes of the Republic of Cuba is a radioactive installation of first category that executes the administration of their radioactive waste under authorization of the National Regulatory Authority. The principles of the design and operation of the 'SADR' system for the safe administration of the radioactive waste and liquid effluents are presented. The Visual Basic 6 platform for the programming of the SADR is used and through of their schematic representation, the control flows and of data of the 7 modules that conform it are shown. For each module the functions are described and it presents an image of the corresponding interface. With the SADR its can be carried out the one registration and the upgrade of the inventory of radioactive waste, the planning of those disqualification operations, the annual consolidation of the volumes of waste generated and disqualified, the evaluation of specific and general indicators and the one tendencies analysis. The handling of the system through the intranet allows the enter of data from the operations place with the radioactive wastes. The results of the operation of the SADR show the utility of this work to elevate the efficiency of the administration of the radioactive wastes. (Author)

  2. Development of modern safe systems of work at the Imperial College Reactor Centre and their application to neutron detector testing and nuclear training courses

    International Nuclear Information System (INIS)

    Full text: The 'CONSORT'-design reactor is owned by, and licensed to, Imperial College of Science, Technology and Medicine, and has been in continuous safe operation since 1965. Today, it is the only civil research reactor left in the UK. CONSORT is designated a 'low power research reactor' and is rated at 100 kW. This paper concentrates on the issues that have been addressed in ensuring that worker doses are maintained As Low As Reasonably Practicable or ALARP, and describes how robust systems have been implemented to ensure that all assessments are in line with this principle. Two case studies are described in detail showing the experience gained in the past few years at the Reactor Centre; these will provide useful information that managers of similar facilities may wish to consider in formulating their own arrangements. Imperial College operates the smallest of the UK nuclear licensed sites. Although the operation of the reactor is different to, and involves risks of much lower magnitude than, nuclear power plants and fuel cycle facilities, our activities are governed by the same 36 standard licence conditions of the Nuclear Installations Act 1965. In addition the site requires assessment of 'reasonably foreseeable' emergencies under the REPPIR (Radiation Emergency Preparedness and Public Information) regulations [1] and control of work with ionising radiation under IRR (Ionising Radiation Regulations) [2] and RSA (Radioactive Substances Act) [3]. These regulations and nuclear site licence conditions lead to more clearly defined sets of procedures and assessments of competency, than may be required in other parts of the college or other similar academic institutions. This paper will discuss the way these regulations are addressed through the two case studies. The approach adopted at the Reactor Centre to producing Safe Systems of Work is based initially on risk assessment of the planned task, taking into account both radiological, nuclear and conventional

    Full Text Available We undertook this study to determine the safe limits of capsulorhexis during nucleus expression in 40 eyes of patients undergoing extracapsular cataract extraction (ECCE with a posterior chamber intraocular lens (PC IOL implantation and in 30 cadaver eyes. In group I (patient eyes, capsulorhexis of 4.5 to 7.5 mm was performed and the nucleus was expressed by hydrodissection. The nuclei measured 4.5 to 9.0 mm. One relaxing incision at 12 o′clock position had to be placed in 9 patients. In group II (cadaver eyes, continuous curvilinear capsulotomies of 4.0, 4.5, 5.0, 5.5, 6.0 and 6.5 mm were made in 5 eyes each. No relaxing incisions were placed. In both the groups, nuclei of all sizes could be safely delivered through intact capsulotomies measuring 5.5 mm or more. In two patient eyes, posterior capsule rupture occurred with rhexis measuring 4.5 and 5.0 mm, respectively. In the cadaver eyes, intracapsular extraction occurred in 4 eyes with rhexis measuring 5.0 mm or less. We conclude that a rhexis less than 5.5 mm is not safe for nucleus delivery during ECCE.

    The separation of Cd and Ni from Ni-Cd batteries using an aqueous two-phase system (ATPS) composed of copolymer L35, Li{sub 2}SO{sub 4} and water is investigated. The extraction behavior of these metals from the bottom phase (BP) to the upper phase (UP) of the ATPS is affected by the amount of added extractant (potassium iodide), tie-line length (TLL), mass ratio between the phases of the ATPS, leaching and dilution factor of the battery samples. Maximum extraction of Cd (99.2 {+-} 3.1)% and Ni (10.6 {+-} 0.4)% is obtained when the batteries are leached with HCl, under the following conditions: 62.53% (w/w) TLL, concentration of KI equal to 50.00 mmol kg{sup -1}, mass ratio of the phases equal to 0.5 and a dilution factor of battery samples of 35. This novel methodology is efficient to separate the metals in question, with the advantage of being environmentally safe, since water is the main constituent of the ATPS, which is prepared with recyclable and biodegradable compounds.

  13. Safe handling of tritium

    International Nuclear Information System (INIS)

    The main objective of this publication is to provide practical guidance and recommendations on operational radiation protection aspects related to the safe handling of tritium in laboratories, industrial-scale nuclear facilities such as heavy-water reactors, tritium removal plants and fission fuel reprocessing plants, and facilities for manufacturing commercial tritium-containing devices and radiochemicals. The requirements of nuclear fusion reactors are not addressed specifically, since there is as yet no tritium handling experience with them. However, much of the material covered is expected to be relevant to them as well. Annex III briefly addresses problems in the comparatively small-scale use of tritium at universities, medical research centres and similar establishments. However, the main subject of this publication is the handling of larger quantities of tritium. Operational aspects include designing for tritium safety, safe handling practice, the selection of tritium-compatible materials and equipment, exposure assessment, monitoring, contamination control and the design and use of personal protective equipment. This publication does not address the technologies involved in tritium control and cleanup of effluents, tritium removal, or immobilization and disposal of tritium wastes, nor does it address the environmental behaviour of tritium.

  14. Safe in salt

    International Nuclear Information System (INIS)

    The geologic history of the 'Germanic Basin', in which saline sediments were piled up in different strata over a period of nearly 100 million years, and the formation of 'salt deposits' as a consequence of tectonic movements (strata bends, dislocations of strata) in the north-west german region are described. As compact rock being 'harnessed' in the ground, mineral salt is completely impermeable to gases and liquids. Its plasticity prevents any formation of pores or crevasses resp. eliminates existing ones. This impermeable quality has been used technically for a long time in order to use solution-mined caverns for the storage of petroleum or gas without containers. Furthermore, for storing radioactive substances it is of particular importance that mineral salt has the highest thermal conductivity of all sedimentary rocks, so that a local heat up will be distributed quickly. All considerations on a safe storage stem from the fact that all actions take place within rock-mechanically homogeneous mineral salt. Bands of different rocks lead to discontinuities and may render a mechanical calculation impossible in some cases. A careful exploration of the internal structure of salt deposits is therefore one of the most important prerequisites for a safe storage of substances to be separated from the biosphere. (RB)

    Purpose: To analyze the durability and toxicity of radiotherapeutic local ablative therapy (LAT) applied to extra-central nervous system (eCNS) disease progression in anaplastic lymphoma kinase-positive non-small cell lung cancer (NSCLC) patients. Methods and Materials: Anaplastic lymphoma kinase-positive NSCLC patients receiving crizotinib and manifesting ≤4 discrete sites of eCNS progression were classified as having oligoprogressive disease (OPD). If subsequent progression met OPD criteria, additional courses of LAT were considered. Crizotinib was continued until eCNS progression was beyond OPD criteria or otherwise not suitable for further LAT. Results: Of 38 patients, 33 progressed while taking crizotinib. Of these, 14 had eCNS progression meeting OPD criteria suitable for radiotherapeutic LAT. Patients with eCNS OPD received 1-3 courses of LAT with radiation therapy. The 6- and 12-month actuarial local lesion control rates with radiation therapy were 100% and 86%, respectively. The 12-month local lesion control rate with single-fraction equivalent dose >25 Gy versus ≤25 Gy was 100% versus 60% (P=.01). No acute or late grade >2 radiation therapy-related toxicities were observed. Median overall time taking crizotinib among those treated with LAT versus those who progressed but were not suitable for LAT was 28 versus 10.1 months, respectively. Patients continuing to take crizotinib for >12 months versus ≤12 months had a 2-year overall survival rate of 72% versus 12%, respectively (P<.0001). Conclusions: Local ablative therapy safely and durably eradicated sites of individual lesion progression in anaplastic lymphoma kinase-positive NSCLC patients receiving crizotinib. A dose–response relationship for local lesion control was observed. The suppression of OPD by LAT in patients taking crizotinib allowed an extended duration of exposure to crizotinib, which was associated with longer overall survival.

  19. Safeguards Automated Facility Evaluation (SAFE) methodology

    International Nuclear Information System (INIS)

    The SAFE procedure is an efficient method of evaluating the physical protection system of a nuclear facility. Since the algorithms used in SAFE for path generation and evaluation are analytical, many paths can be evaluated with a modest investment in computer time. SAFE is easy to use because the information required is well-defined and the interactive nature of this procedure lends itself to straightforward operation. The modular approach that has been taken allows other functionally equivalent modules to be substituted as they become available. The SAFE procedure has broad applications in the nuclear facility safeguards field as well as in the security field in general. Any fixed facility containing valuable materials or components to be protected from theft or sabotage could be analyzed using this same automated evaluation technique

    The Safe Motherhood Initiative was launched in 1988 as a global effort to halve maternal mortality and morbidity by the year 2000. The program uses a combination of health and nonhealth strategies to emphasize the need for maternal health services, extend family planning services, and improve the status of women. The maternal mortality rate (per 100,000 live births) is 390 for the world, 20-30 for developed countries, 450 for developing countries, and 420 for Asia. This translates into 308,000 maternal deaths in Asia, of which 100,000 occur in India. The direct causes of maternal mortality include sepsis, hemorrhage, eclampsia, and ruptured uterus. Indirect causes occur when associated medical conditions, such as anemia and jaundice, are exacerbated by pregnancy. Underlying causes are ineffective health services, inadequate obstetric care, unregulated fertility, infections, illiteracy, early marriage, poverty, malnutrition, and ignorance. India's Child Survival and Safe Motherhood Program seeks to achieve immediate improvements by improving health care. Longterm improvements will occur as nutrition, income, education, and the status of women improve. Improvements in health care will occur in through the provision of 1) essential obstetric care for all women (which will be essentially designed for low-risk women), 2) early detection of complications during pregnancy and labor, and 3) emergency services. Services will be provided to pregnant women at their door by field staff, at a first referral hospital, perhaps at maternity villages where high risk cases can be housed in the latter part of their pregnancies, and through the continual accessibility of government vehicles. In addition, family planning services will be improved so that fertility regulation can have its expected beneficial effect on the maternal mortality rate. The professional health organizations in India will also play a vital role in the success of this effort to reduce maternal mortality. PMID

    Drying can add value, facilitate transport and extend the storage life of agro-products; therefore, in developing countries with poorly established cool-chains, drying is particularly effective. Furthermore, drying within small-scale village-based enterprises contributes to rural development. However, most equipment suitable to such operations yields a product of non-uniform quality and shows low levels of energy efficiency. The aim of this research was to improve the batch uniformity and the energy efficiency of a cabinet dryer suitable for smallholder farmers. Experiments were carried out with the cooperation of a dryer manufacturer and a group of users. On each trial 144.5 kg of peeled and deseeded litchis were placed at the dryer's 17 trays, that were stacked atop each other. Moisture content (wet basis) was reduced from 87 to 23 % in about 15.5 h. It was found that a low-cost modification to the dryer chamber's air inlet was able to improve heat distribution and increase the uniformity of the fruit's moisture content. In the original design, at the end of the drying process, moisture content of the fruits on the top tray was 38 % while at the bottom tray was 12 %. The modification to the dryer reduced this disparity and the final moisture content of the fruits placed at the top tray was 25 % while at the bottom tray was 21 %. In addition, the modification reduced the dryer's air mass flow from 0.3 to 0.1 kg s(-1) without jeopardizing drying forces, consequently the dryer energy efficiency increased from 33 to 42 %.

  5. Law no. 111/1996 on the safe deployment of nuclear activities - A law central to the Romanian nuclear law system

    International Nuclear Information System (INIS)

    Law no. 111/1996 on the safe deployment of nuclear activities was published in its original form in the Official Gazette of Romania, Part no. 267 of 29th October 1996. The complexity of this law prevents from performing a comprehensive analysis of the legal provisions thereof for which reason the author shall review only those aspects he consider to be relevant to the issues dealt with by this law. Furthermore, as the author intends his undertaking to be a comparative analysis of Law no. 111/1996 in its successive stages - from its issue till the present - he uses mostly the present tense even though the law has been amended and in some respects the changes are quite significant. The presentation contains the following three sections: 1. Passing of Law no. 111/1996 on the safe deployment of nuclear activities - a turning point in the development of the Romanian nuclear law; 2. The successive modifications of Law no. 111/1996 on safe deployment of nuclear activities; 3. Law no. 193/2003 for the modification and completion of Law no. 111/1996 on the safe deployment of nuclear activities - a key moment in the modernization of Romanian nuclear law and harmonization with the relevant international requirement. In conclusion, the issue of Law no. 111/1996 on safe deployment of nuclear activities represents a turning point in the development of Romanian nuclear law. From this moment on one may regard it as a modern area of the Romanian law, European in spirit. The pre-existent legal framework - namely the Law no. 61/1974 on the deployment of activities in the Romanian nuclear field - was no longer up to the existing standards and its replacement by a new, modern law, fully harmonized with the European and NATO accession requirements was a must. Such a new, European law was to fully guarantee the safe deployment of nuclear activities for exclusively peaceful purposes, so that the requirements regarding the nuclear safety, protection of professionally exposed personnel

    Full Text Available The paper examines both field experience and research on the prevention of the exponential growth of aflatoxins during multi-month post harvest storage in hot, humid countries. The approach described is the application of modern safe storage methods using flexible, Ultra Hermetic™ structures that create an unbreatheable atmosphere through insect and microorganism respiration alone, without use of chemicals, fumigants, or pumps. Laboratory and field data are cited and specific examples are given describing the uses of Ultra Hermetic storage to prevent the growth of aflatoxins with their significant public health consequences. Also discussed is the presently limited quantitative information on the relative occurrence of excessive levels of aflatoxin (>20 ppb before versus after multi-month storage of such crops as maize, rice and peanuts when under high humidity, high temperature conditions and, consequently, the need for further research to determine the frequency at which excessive aflatoxin levels are reached in the field versus after months of post-harvest storage. The significant work being done to reduce aflatoxin levels in the field is mentioned, as well as its probable implications on post harvest storage. Also described is why, with some crops such as peanuts, using Ultra Hermetic storage may require injection of carbon dioxide or use of an oxygen absorber as an accelerant. The case of peanuts is discussed and experimental data is described.

  9. Making Our Food Safe

    International Nuclear Information System (INIS)

    Full text: As civilization has progressed societies have strived to make food safer; from using fire to cook our food, and boiling our water to make it safe to drink, advances in technology have helped kill microorganisms that can make food unsafe. The FAO/IAEA Joint Division helps provide technical assistance to Member States that want to implement irradiation technology in making their food safer. Food and waterborne diarrhoeal diseases are estimated to kill roughly 2.2 million people annually, of which 1.9 million are children. Irradiating some of the foods we eat can save many of these lives by reducing the risk of food poisoning and killing the organisms that cause disease. Irradiation works by treating food with a small dose of ionizing radiation, this radiation disrupts the bacteria’s DNA and cell membranes structure stopping the organism from reproducing or functioning, but does not make the food radioactive. It can be applied to a variety of foods from spices and seasonings, to fruits and vegetables and is similar to pasteurization, but without the need for high temperatures that might impair food quality.

  10. Safe Handling of Radioisotopes

    International Nuclear Information System (INIS)

    Under its Statute the International Atomic Energy Agency is empowered to provide for the application of standards of safety for protection against radiation to its own operations and to operations making use of assistance provided by it or with which it is otherwise directly associated. To this end authorities receiving such assistance are required to observe relevant health and safety measures prescribed by the Agency. As a first step, it has been considered an urgent task to provide users of radioisotopes with a manual of practice for the safe handling of these substances. Such a manual is presented here and represents the first of a series of manuals and codes to be issued by the Agency. It has been prepared after careful consideration of existing national and international codes of radiation safety, by a group of international experts and in consultation with other international bodies. At the same time it is recommended that the manual be taken into account as a basic reference document by Member States of the Agency in the preparation of national health and safety documents covering the use of radioisotopes.

    The Hydrogen Safety Panel brings a broad cross-section of expertise from the industrial, government, and academic sectors to help advise the U.S. Department of Energy’s (DOE) Fuel Cell Technologies Office through its work in hydrogen safety, codes, and standards. The Panel’s initiatives in reviewing safety plans, conducting safety evaluations, identifying safety-related technical data gaps, and supporting safety knowledge tools and databases cover the gamut from research and development to demonstration and deployment. The Panel’s recent work has focused on the safe deployment of hydrogen and fuel cell systems in support of DOE efforts to accelerate fuel cell commercialization in early market applications: vehicle refueling, material handling equipment, backup power for warehouses and telecommunication sites, and portable power devices. This paper resulted from observations and considerations stemming from the Panel’s work on early market applications. This paper focuses on hydrogen system components that are installed in outdoor enclosures. These enclosures might alternatively be called “cabinets,” but for simplicity, they are all referred to as “enclosures” in this paper. These enclosures can provide a space where a flammable mixture of hydrogen and air might accumulate, creating the potential for a fire or explosion should an ignition occur. If the enclosure is large enough for a person to enter, and ventilation is inadequate, the hydrogen concentration could be high enough to asphyxiate a person who entered the space. Manufacturers, users, and government authorities rely on requirements described in codes to guide safe design and installation of such systems. Except for small enclosures used for hydrogen gas cylinders (gas cabinets), fuel cell power systems, and the enclosures that most people would describe as buildings, there are no hydrogen safety requirements for these enclosures, leaving gaps that must be addressed. This paper proposes that

  12. Supplement analysis for the proposed upgrades to the tank farm ventilation, instrumentation, and electrical systems under Project W-314 in support of tank farm restoration and safe operations

    International Nuclear Information System (INIS)

    The mission of the TWRS program is to store, treat, and immobilize highly radioactive tank waste in an environmentally sound, safe, and cost-effective manner. Within this program, Project W-314, Tank Farm Restoration and Safe Operations, has been established to provide upgrades in the areas of instrumentation and control, tank ventilation, waste transfer, and electrical distribution for existing tank farm facilities. Requirements for tank farm infrastructure upgrades to support safe storage were being developed under Project W-314 at the same time that the TWRS EIS alternative analysis was being performed. Project W-314 provides essential tank farm infrastructure upgrades to support continued safe storage of existing tank wastes until the wastes can be retrieved and disposed of through follow-on TWRS program efforts. Section4.0 provides a description of actions associated with Project W-314. The TWRS EIS analyzes the environmental consequences form the entire TWRS program, including actions similar to those described for Project W-314 as a part of continued tank farm operations. The TWRS EIS preferred alternative was developed to a conceptual level of detail to assess bounding impact areas. For this Supplement Analysis, in each of the potential impact areas for Project W-314, the proposed action was evaluated and compared to the TWRS EIS evaluation of the preferred alternative (Section 5.0). Qualitative and/or quantitative comparisons are then provided in this Supplement Analysis to support a determination on the need for additional National Environmental Policy Act (NEPA) analysis. Based on this Supplement Analysis, the potential impacts for Project W-314 would be small in comparison to and are bounded by the impacts assessed for the TWRS EIS preferred alternative, and therefore no additional NEPA analysis is required (Section 7.0)

    The Joggins Fossil Cliffs (Nova Scotia, Canada) is a UNESCO World Heritage Site representing the Late Carboniferous time period (ca. 310-325 mya). The site was formative for Charles Lyell in constructing his geological principles. It is still the best place in the world to view fossils from the Carboniferous 'Coal Age', a time when much of the coal that we use today was formed. The Joggins Fossil Institute is a not-for-profit, charitable organization that co-manages the site with the Province of Nova Scotia. Its mission is to conduct research and educate the public about Earth Sciences through interpretation (e.g., exhibits and tours of the site) and a fossil collection. Fossils are the only direct evidence of how biodiversity has changed over deep time; they are the texts and artifacts that we 'read' in order to understand the development of the earth and that can help humans decipher the deeper histories that produced us. At the Joggins Fossil Institute we primarily present the scientific history of the Carboniferous Period through the use of fossils, but we are also interested in the cultural history of coal production and usage, which is an essential part of the region's economic history. However, this industry has also contributed to climate change and the emergence of a new geological age called the Anthropocene. We encourage our visitors to connect palaeontology and coal energy consumption, and ask them to consider how different values (economic and scientific) are attributed to both coal and fossils; such questions lead directly to discussions about conservation issues. The Joggins Fossil Institute has partnered with the Faculty of Arts at nearby Mount Allison University to create an exhibit that will interrogate these questions. The medium of display that we have chosen is the "cabinet of wonders" or "cabinet of curiosity," which has a rich tradition in western cultures going back to the Renaissance. A venerable intersection of art and science, the cabinet

  3. 3D Radiotherapy Can Be Safely Combined With Sandwich Systemic Gemcitabine Chemotherapy in the Management of Pancreatic Cancer: Factors Influencing Outcome

    International Nuclear Information System (INIS)

    Purpose: The aim of this Phase II study was to examine whether concurrent continuous infusion 5-fluorouracil (CI 5FU) plus three-dimensional conformal planning radiotherapy sandwiched between gemcitabine chemotherapy is effective, tolerable, and safe in the management of pancreatic cancer. Methods and Materials: Patients were enrolled in two strata: (1) resected pancreatic cancer at high risk of local relapse (postsurgery arm, n = 22) or (2) inoperable pancreatic cancer in head or body without metastases (locally advanced arm, n = 41). Gemcitabine was given at 1,000 mg/m2 weekly for 3 weeks followed by 1 week rest then 5-6 weeks of radiotherapy and concurrent CI 5FU (200 mg/m2/day). After 4 weeks' rest, gemcitabine treatment was reinitiated for 12 weeks. Results: For the two arms combined, treatment-related Grade 3 and 4 toxicities were reported by 25 (39.7%) and 7 (11.1%) patients, respectively. No significant late renal or hepatic toxicity was observed. In the postsurgery arm (R1 54.5%), median time to progressive disease from surgery was 11.0 months, median time to failure of local control was 32.9 months, and median survival time was 15.6 months. The 1- and 2-year survival rates were 63.6% and 31.8%. No significant associations between outcome and mutations in K-ras or TP53 or microsatellite instability were identified. Post hoc investigation of cancer antigen 19-9 levels found baseline levels and increases postbaseline were associated with shorter survival (p = 0.0061 and p < 0.0001, respectively). Conclusions: This three-dimensional chemoradiotherapy regimen is safe and promising, with encouraging local control for a substantial proportion of patients, and merits testing in a randomized trial

    Full Text Available Abstract Background Pre-hospital electrocardiogram (ECG transmission to an expert for interpretation and triage reduces time to acute percutaneous coronary intervention (PCI in patients with ST elevation Myocardial Infarction (STEMI. In order to detect all STEMI patients, the ECG should be transmitted in all cases of suspected acute cardiac ischemia. The aim of this study was to examine the ability of an artificial neural network (ANN to safely reduce the number of ECGs transmitted by identifying patients without STEMI and patients not needing acute PCI. Methods Five hundred and sixty ambulance ECGs transmitted to the coronary care unit (CCU in routine care were prospectively collected. The ECG interpretation by the ANN was compared with the diagnosis (STEMI or not and the need for an acute PCI (or not as determined from the Swedish coronary angiography and angioplasty register. The CCU physician's real time ECG interpretation (STEMI or not and triage decision (acute PCI or not were registered for comparison. Results The ANN sensitivity, specificity, positive and negative predictive values for STEMI was 95%, 68%, 18% and 99%, respectively, and for a need of acute PCI it was 97%, 68%, 17% and 100%. The area under the ANN's receiver operating characteristics curve for STEMI detection was 0.93 (95% CI 0.89-0.96 and for predicting the need of acute PCI 0.94 (95% CI 0.90-0.97. If ECGs where the ANN did not identify a STEMI or a need of acute PCI were theoretically to be withheld from transmission, the number of ECGs sent to the CCU could have been reduced by 64% without missing any case with STEMI or a need of immediate PCI. Conclusions Our ANN had an excellent ability to predict STEMI and the need of acute PCI in ambulance ECGs, and has a potential to safely reduce the number of ECG transmitted to the CCU by almost two thirds.

    2014-01-01

    Large vacuum systems at CERN (Large Hadron Collider - LHC, Low Energy Ion Rings - LEIR...) require bake-out to achieve ultra-high vacuum specifications. The bake-out cycle is used to decrease the outgassing rate of the vacuum vessel and to activate the Non-Evaporable Getter (NEG) thin film. Bake-out control is a Proportional-Integral-Derivative (PID) regulation with complex recipes, interlocks and troubleshooting management and remote control. It is based on mobile Programmable Logic Controller (PLC) cabinets, fieldbus network and Supervisory Control and Data Acquisition (SCADA) application. The CERN vacuum installations include more than 7 km of baked vessels; using mobile cabinets reduces considerably the cost of the control system. The cabinets are installed close to the vacuum vessels during the time of the bake-out cycle. Mobile cabinets can be used in any of the CERN vacuum facilities. Remote control is provided through a fieldbus network and a SCADA application

    The Safe Affordable Fission Engine (SAFE) test series addresses Phase 1 Space Fission Systems issues in particular non-nuclear testing and system integration issues leading to the testing and non-nuclear demonstration of a 400-kW fully integrated flight unit. The first part of the SAFE 30 test series demonstrated operation of the simulated nuclear core and heat pipe system. Experimental data acquired in a number of different test scenarios will validate existing computational models, demonstrated system flexibility (fast start-ups, multiple start-ups/shut downs), simulate predictable failure modes and operating environments. The objective of the second part is to demonstrate an integrated propulsion system consisting of a core, conversion system and a thruster where the system converts thermal heat into jet power. This end-to-end system demonstration sets a precedent for ground testing of nuclear electric propulsion systems. The paper describes the SAFE 30 end-to-end system demonstration and its subsystems

  13. Eye safe laser range finders

    International Nuclear Information System (INIS)

    During the 1970's, Ruby (Q switched) laser based range finders with a wavelength of 694nm were first used. These lasers operated in a pulse mode within the visible light range and produced a risk for the eye retina. The laser beam striking the macula could damage the eye and might cause blindness. Over the years, Nd:YAG (Q switched) lasers were developed (operating at 1064nm) for range finding and designation uses. The wavelength of these lasers, operating in the near Infra-Red range (invisible), is also focused tightly on the retina. The human eye does not respond to the invisible light so there is no natural protection (eye blink reflex) as in the visible light. The operation of these lasers worldwide, especially when the laser beam is exposed, causes occasional eye accidents. Another risk is stemming from the use of observation systems with a high optical gain, in the laser operation areas, which enlarge the range of risk quite significantly. Therefore, research and development efforts were invested in order to introduce eye safe lasers. One of the solutions for this problem is presented in following document

    Full Text Available Abstract Background The near-patient environment is often heavily contaminated, yet the decontamination of near-patient surfaces and equipment is often poor. The Nanoclave Cabinet produces large amounts of ultraviolet-C (UV-C radiation (53 W/m2 and is designed to rapidly disinfect individual items of clinical equipment. Controlled laboratory studies were conducted to assess its ability to eradicate a range of potential pathogens including Clostridium difficile spores and Adenovirus from different types of surface. Methods Each test surface was inoculated with known levels of vegetative bacteria (106 cfu/cm2, C. difficile spores (102-106 cfu/cm2 or Adenovirus (109 viral genomes, placed in the Nanoclave Cabinet and exposed for up to 6 minutes to the UV-C light source. Survival of bacterial contaminants was determined via conventional cultivation techniques. Degradation of viral DNA was determined via PCR. Results were compared to the number of colonies or level of DNA recovered from non-exposed control surfaces. Experiments were repeated to incorporate organic soils and to compare the efficacy of the Nanoclave Cabinet to that of antimicrobial wipes. Results After exposing 8 common non-critical patient care items to two 30-second UV-C irradiation cycles, bacterial numbers on 40 of 51 target sites were consistently reduced to below detectable levels (≥ 4.7 log10 reduction. Bacterial load was reduced but still persisted on other sites. Objects that proved difficult to disinfect using the Nanoclave Cabinet (e.g. blood pressure cuff were also difficult to disinfect using antimicrobial wipes. The efficacy of the Nanoclave Cabinet was not affected by the presence of organic soils. Clostridium difficile spores were more resistant to UV-C irradiation than vegetative bacteria. However, two 60-second irradiation cycles were sufficient to reduce the number of surface-associated spores from 103 cfu/cm2 to below detectable levels. A 3 log10 reduction in

    Full Text Available Dans la France des Lumières, la culture de la curiosité est un phénomène de mode mais surtout un jeu social et intellectuel. La présente étude entend retracer l’histoire d’une trentaine de cabinets féminins de curiosité tenus à cette époque. Des femmes fortunées de l’aristocratie et de la bourgeoisie parisienne et provinciale ont alors constitué sous l’emprise de leur libido sciendi des cabinets d’alchimie, de minéralogie, de physique‑chimie, d’histoire naturelle et d’anatomie naturelle et artificielle. Ces cabinets obéissent à une typologie particulière. Il en existe deux catégories : les cabinets d’amateurs, constitués pour la parade et le spectacle des visiteurs et fonctionnant comme de véritables écoles de plaisirs intellectuels et éducatifs ; les cabinets à finalité scientifique et didactique, formés par des savantes expérimentées qui se livrent dans leurs laboratoires à des recherches personnelles et expérimentales au nom des progrès de la science médicale et de l’instruction publique. La réflexion porte aussi sur le fonctionnement de ces cabinets privés de curiosité, particulièrement sur leur mode de constitution, leur décor intérieur ainsi que sur le contenu des collections qui nécessitaient certaines techniques d’organisation, d’acquisition et de conservation communes à celles de leurs homologues masculins.During the Enlightenment in France, curiosity culture constituted both a fashion and an intellectual and social game.  This article explores thirty cabinets of  curiosities run by women during this period. Wealthy women from the Parisiain and provincial aristocracy and middle classes organized cabinets in alchemy, mineralogy, physics and chemistry, natural history and biology studies. These cabinets can be divided into two distinct categories. The first represented amateur interests; they were developed for show and served as schools for intellectual and

    2016-08-01

    This paper focuses on improving the performance of the vertical open refrigerated display cabinets (VORDC) by optimizing the structure of deflector, which is affected by inlet velocity and velocity distribution of air curtains. The results show that the temperature of products located at the front and at the rear reduces as the increases of inlet velocity of air curtains. The increase of the inlet velocity of air curtains can strengthen the disturbance inside the VORDC, and also decrease the temperature of products inside the VORDC; the increase of the outer velocity of air curtain will exacerbate the disturbance outside the VORDC and decrease air curtain's performance. The present study can provide a theoretical foundation for the design of VORDC.

  19. Safeguards Automated Facility Evaluation (SAFE) methodology

    International Nuclear Information System (INIS)

    An automated approach to facility safeguards effectiveness evaluation has been developed. This automated process, called Safeguards Automated Facility Evaluation (SAFE), consists of a collection of a continuous stream of operational modules for facility characterization, the selection of critical paths, and the evaluation of safeguards effectiveness along these paths. The technique has been implemented on an interactive computer time-sharing system and makes use of computer graphics for the processing and presentation of information. Using this technique, a comprehensive evaluation of a safeguards system can be provided by systematically varying the parameters that characterize the physical protection components of a facility to reflect the perceived adversary attributes and strategy, environmental conditions, and site operational conditions. The SAFE procedure has broad applications in the nuclear facility safeguards field as well as in the security field in general. Any fixed facility containing valuable materials or components to be protected from theft or sabotage could be analyzed using this same automated evaluation technique

  20. Inactivated Eyedrop Influenza Vaccine Adjuvanted with Poly(I:C Is Safe and Effective for Inducing Protective Systemic and Mucosal Immunity.

    Directory of Open Access Journals (Sweden)

    Eun-Do Kim

    Full Text Available The eye route has been evaluated as an efficient vaccine delivery routes. However, in order to induce sufficient antibody production with inactivated vaccine, testing of the safety and efficacy of the use of inactivated antigen plus adjuvant is needed. Here, we assessed various types of adjuvants in eyedrop as an anti-influenza serum and mucosal Ab production-enhancer in BALB/c mice. Among the adjuvants, poly (I:C showed as much enhancement in antigen-specific serum IgG and mucosal IgA antibody production as cholera toxin (CT after vaccinations with trivalent hemagglutinin-subunits or split H1N1 vaccine antigen in mice. Vaccination with split H1N1 eyedrop vaccine antigen plus poly(I:C showed a similar or slightly lower efficacy in inducing antibody production than intranasal vaccination; the eyedrop vaccine-induced immunity was enough to protect mice from lethal homologous influenza A/California/04/09 (H1N1 virus challenge. Additionally, ocular inoculation with poly(I:C plus vaccine antigen generated no signs of inflammation within 24 hours: no increases in the mRNA expression levels of inflammatory cytokines nor in the infiltration of mononuclear cells to administration sites. In contrast, CT administration induced increased expression of IL-6 cytokine mRNA and mononuclear cell infiltration in the conjunctiva within 24 hours of vaccination. Moreover, inoculated visualizing materials by eyedrop did not contaminate the surface of the olfactory bulb in mice; meanwhile, intranasally administered materials defiled the surface of the brain. On the basis of these findings, we propose that the use of eyedrop inactivated influenza vaccine plus poly(I:C is a safe and effective mucosal vaccine strategy for inducing protective anti-influenza immunity.

    Tourniquets are often needed for optimized phalangeal surgeries. However, few surgeons forget to remove them and caused ischemic injuries. We have a modified method to create a safe finger tourniquet for short duration finger surgeries, which can avoid such tragedy. It is done by donning a glove, cutting the tip of the glove over the finger of interest, and rolling the glove finger to the base. From 2010 to 2013, approximately 54 patients underwent digital surgical procedures with our safe finger tourniquet. Because the glove cannot be forgotten to be removed, the tourniquet must be released and removed. This is a simple and efficient way to apply a safe finger tourniquet by using hand rubber glove for a short-term bloodless finger surgery and can achieve an excellent surgical result. PMID:26855166

  4. Comment on Asymptotically Safe Inflation

    CERN Document Server

    Tye, S -H Henry

    2010-01-01

    We comment on Weinberg's interesting analysis of asymptotically safe inflation (arXiv:0911.3165). We find that even if the gravity theory exhibits an ultraviolet fixed point, the energy scale during inflation is way too low to drive the theory close to the fixed point value. We choose the specific renormalization groupflow away from the fixed point towards the infrared region that reproduces the Newton's constant and today's cosmological constant. We follow this RG flow path to scales below the Planck scale to study the stability of the inflationary scenario. Again, we find that some fine tuning is necessary to get enough efolds of infflation in the asymptotically safe inflationary scenario.

  5. Manpower development for safe operation of nuclear power plant. China. Main steam bypass system operation and maintenance. Task: 6.1.6. Technical report

    International Nuclear Information System (INIS)

    This mission concentrated on the Steam Bypass system of Qinshan Nuclear Power Plant. The system had experienced spurious opening of the bypass valves, disrupting the steam pressure control and the steam generator level control system. A series of commissioning type tests were defined which should allow the operators to revise the setpoints used in the control of the bypass system, and thus prevent spurious opening while maintaining the desired steam pressure control during power maneuvering. Training also included giving experience from other operating plants on aspects of steam and feedwater systems and components, especially as this experience affected maintenance or gave rise to problems. Steam generated maintenance experience is especially applicable, and a future mission is planned for an expert in this field. In addition other aspects of the Chinese nuclear program was assessed to guide future missions. This included assessment of operating procedures from an availability point of view

    Full Text Available The Korea Railroad Research Institute (KRRI has developed a bimodal tram and advanced bus rapid transit (BRT system which is an optimized public transit system created by mixing the railway’s punctual operation and the bus’ easy and convenient access. The bimodal tram system provides mass-transportation service with an eco-friendly and human-centered approach. Natural disasters have been increasing worldwide in recent years, including floods, snow, and typhoons disasters. Flooding is the most frequent natural disaster in many countries and is increasingly a concern with climate change; it seriously affects people’s lives and productivity, causing considerable economic loss and significant damage. Enhanced conventional disaster management systems are needed to support comprehensive actions to secure safety and convenience. The objective of this study is to develop a prototype version of a Web GIS-based bimodal tram disaster management system (BTDMS using the Storm Water Management Model (SWMM 5.0 to enhance on-time operation and safety of the bimodal tram system. The BTDMS was tested at the bimodal tram test railroad by simulating probable maximum flood (PMF and snow melting for forecasting flooding and snow covered roads. This result could provide the basis for plans to protect against flooding disasters and snow covered roads in operating the bimodal tram system. The BTDMS will be used to assess and predict weather impacts on roadway conditions and operations and thus has the potential to influence economic growth. The methodology presented in this paper makes it possible to manage impacts of flooding and snowfall on urban transportation and enhance operation of the bimodal tram system. Such a methodology based on modeling could be created for most metropolitan areas in Korea and in many other countries.

    The Maglev control computer system should be designed to verifiably possess high reliability and safety as well as high availability to make Maglev a dependable and attractive transportation alternative to the public. A Maglev control computer system has been designed using a design-for-validation methodology developed earlier under NASA and SDIO sponsorship for real-time aerospace applications. The present study starts by defining the maglev mission scenario and ends with the definition of a maglev control computer architecture. Key intermediate steps included definitions of functional and dependability requirements, synthesis of two candidate architectures, development of qualitative and quantitative evaluation criteria, and analytical modeling of the dependability characteristics of the two architectures. Finally, the applicability of the design-for-validation methodology was also illustrated by applying it to the German Transrapid TR07 maglev control system.

    In the light of measures to be adopted for a reduction of CO[sub 2] emissions, a special emphasis needs to be placed on the application of regenerative energies juxtaposed to the enhancement of the efficiencies of fossil-fuelled power stations and further extension of nuclear energy applications. In industrialized countries with compound power networks, the feeding of regenerative energies means direct savings in fossil fuels and a reduction of CO[sub 2] production if the local power grid is capable of absorbing that power supply which fluctuates across time. Once this absorption capacity has been exhausted, we will be faced with the problem of intermediate storage of electric power. As a rule, island-type systems cannot dispense with a storage system at all and regenerative energy technologies like photovoltaics will not be applied unless suitable power storage systems are available. The author discusses the state of development of electrochemical energy converters and storage systems and their future application options. (orig.)

    A mobile launcher platform atop a crawler-transporter, moves into the Vehicle Assembly Building high bay 2. As part of the Safe Haven project, a once-buried portion of the crawlerway was restored to enable rollout of a Shuttle from this third stacking area. The primary goal of the Safe Haven construction project was to strengthen readiness for hurricane season by expanding the VAB's storage capacity. The new area, in high bay 2, will allow NASA to preassemble stacks and still have room in the VAB to pull a Shuttle back from the pad if severe weather threatens. Potential rollouts of the Space Shuttle to the launch pad from high bay 2 will involve making a turn around the north side of the VAB in contrast to the straight rollouts from high bays 1 and 3, on the east side of the VAB facing the launch pads.

  7. Addition of oxygen in the inlet of recombiner unit in moderator cover gas system to facilitate recombination of deuterium and oxygen to bring deuterium concentration in safe limits

    International Nuclear Information System (INIS)

    In moderator system of PHWR, radiolytic decomposition of Heavy Water takes place in the Calandria and D2 and O2 are formed. Since the mixture of D2 and O2 is explosive in nature, there is a limit and various action levels for concentration of Oxygen and deuterium in moderator cover gas. The maximum percentage limit of deuterium is 4% v/v in presence of Oxygen present in stoichiometric ratio. In March -2013, the deuterium concentration in moderator cover gas of RAPS-2 increased to 3.0 % v/v and the oxygen concentration was only 0.93% v/v which was much less than the stoichiometric value (1.5% v/v). So it was decided to add oxygen in the inlet of recombiner unit of moderator cover gas system. As in year 1999 there was a fire incident in Darlington unit -3 due to combustion of EDPM which was used as seat material in the isolating valve in the inlet of oxygen pressure regulating valve. EDPM has low ignition temp. So Oxygen addition was not practiced in any other reactors. Oxygen addition was carried out in RAPS-2 with all precaution and with proper planning. Initially oxygen was added with very slow rate of 1 SCFH (Standard Cubic Feet per Hour) intermittently and the process was repeated to see any harmful effect. After qualifying the procedure, oxygen addition was done for 20 hrs at the rate of 2.5 SCFH and D2 concentration came down to 1.95 % v/v. This paper will consists of radiolytic decomposition of D2O, the qualification plan for O2 addition, the data of moderator cover gas and moderator system parameters before, during and after Oxygen addition.

    2010-07-01

    This study demonstrated the use of biomass as a renewable fuel to enrich a greenhouse with carbon dioxide (CO{sub 2}). CO{sub 2} enrichment of greenhouses has been shown to improve crop production whether it occurs from liquid CO{sub 2} or combustion of fossil fuels. Biomass, in the form of wood chips or pellets, has received much interest as a sustainable and economically viable alternative to heat greenhouses. As such, the opportunity exists to convert exhaust gases from a greenhouse wood heating system into a useful resource. CO{sub 2} can be extracted from flue gas via membrane separation instead of electrostatic precipitators. This technique has shown potential for large industries trying to reduce and isolate CO{sub 2} emissions for sequestration and may be applicable to the greenhouse industry. Some research has also been done with wet scrubbers using catalysts to obtain plant fertilizers. Sulphur dioxide (SO{sub 2}) and nitrogen (NO) emissions can be stripped from flue gas to form ammonium sulphate as a valuable byproduct for fertilizer markets. This study will review the potential of these techniques in the summer of 2010 when experiments will be conducted at the Macdonald Campus of McGill University.

  17. Kokanee Stock Status and Contribution of Cabinet Gorge Hatchery, Lake Pend Oreille, Idaho, 1990 Annual Progress Report.

    Energy Technology Data Exchange (ETDEWEB)

    Paragamian, Vaughn L.

    1991-03-01

    Rehabilitation of kokanee Oncorhynchus nerka in Lake Pend Oreille met with some success in 1990, but unexpected results have raised new questions. Estimated kokanee abundance during late August of 1990 was about 6.9 million fish. This is a decline of 19% from 1989, a continued decrease since 1988. The decreased population was attributed to low stocking of hatchery fry (7.3 million), lower wild fry survival in 1990 (1.5%), and exceptionally poor survival of fish ages 3+ and 4+. Average survival of the older fish was only 11% in 1990 compared to 72% in prior years. Compensatory survival was noted for kokanee ages 1+ and 2+, with an average of 81% in 1990 compared to 44% in 1989. Hatchery fry comprised 47% of the total kokanee fry recruitment in 1990 (80% of fry biomass). This contribution ranked third behind 1988 and 1989 since hatchery supplementation began in the 1970s. Survival of hatchery fry was 20%, the second highest since this investigation began. Findings of 1990 indicate a more comprehensive approach to managing kokanee must take into account predator stockings and predator/prey interaction. An unexpected low adult escapement was responsible for an egg-take of only 5.6 million eggs in 1990, 58% of the previous year, which will limit experimental stocking in 1991. Modification of the fish ladder at the Cabinet Gorge Fish Hatchery to improve adult escapement is strongly recommended to increase egg-take. 27 refs., 28 figs., 6 tabs.

    2004-01-01

    A classical problem of mechanics involves a projectile fired from a given point with a given velocity whose direction is varied. This results in a family of trajectories whose envelope defines the border of a 'safe' domain. In the simple cases of a constant force, harmonic potential and Kepler or Coulomb motion, the trajectories are conic curves whose envelope in a plane is another conic section which can be derived either by simple calculus or by geometrical considerations. The case of harmonic forces reveals a subtle property of the maximal sum of distances within an ellipse.

  19. Small intrinsically safe reactor implications

    International Nuclear Information System (INIS)

    Reviewing the history of nuclear power, it is found that peaceful uses of nuclear power are children of the war-like atom. Importance of special growth in a shielded environment is emphasized to exploit fully the advantages of nuclear power. Nuclear power reactors must be safe for their assimilation into society from the points of view of both technology and social psychology. ISR/ISER is identified as a missing link in the development of nuclear power reactors from this perspective and advocated for international development and utilization, being unleashed from the concerns of politicization, safety, and proliferation

    This paper addresses the problem of forbidden states of non safe Petri Net (PN) modelling discrete events systems. To prevent the forbidden states, it is possible to use conditions or predicates associated with transitions. Generally, there are many forbidden states, thus many complex conditions are associated with the transitions. A new idea for computing predicates in non safe Petri nets will be presented. Using this method, we can construct a maximally permissive controller if it exists.

    Radioactive materials have become essential tools in much of the research conducted in the biological and medical sciences. Procedures documented in this manual are only examples of the numerous applications of radioactive materials in the field of parasitology. Like many chemical reagents and much of the equipment found in laboratories, radionuclides can be hazardous if used carelessly. Exposure to large doses of ionizing radiation has been shown to increase the risk of cancer in humans and animals, and has been shown to increase the risk of genetic abnormalities in animal studies. Everyone handling radionuclides in a research program has a responsibility to follow safe laboratory practices for use of these materials. Most research institutions will have a radiation safety organization which may include a Radiation Safety Officer and a Radiation Safety Committee. Procedures developed by the radiation safety organization must be followed in order to protect personnel working with radioactive material, and the public, from unnecessary exposure to radiation. Investigators must also know and follow regulations established by government agencies for the use and disposal of radioactive materials. In this chapter some basic information on procedures for the safe use of radioactive materials in the laboratory is provided. Greater detail for specific operations and radiation safety concerns may be obtained from documents referred to in the text

  2. Safe transport of radioactive material

    International Nuclear Information System (INIS)

    Recently the Agency redefined its policy for education and training in radiation safety. The emphasis is now on long-term strategic planning of general education and training programmes. In line with this general policy the Agency's Standing Advisory Group for the Safe Transport of Radioactive Material (SAGSTRAM) in its 7th meeting (April 1989) agreed that increased training activity should be deployed in the area of transport. SAGSTRAM specifically recommended the development of a standard training programme on this subject area, including audio-visual aids, in order to assist Member States in the implementation of the Agency's Regulations for the Safe Transport of Radioactive Material. This training programme should be substantiated by a biennial training course which is thought to be held either as an Interregional or a Regional Course depending on demand. This training manual, issued as a first publication in the Training Course Series, represents the basic text material for future training courses in transport safety. The topic areas covered by this training manual and most of the texts have been developed from the course material used for the 1987 Bristol Interregional Course on Transport Safety. The training manual is intended to give guidance to the lecturers of a course and will be provided to the participants for retention. Refs, figs and tabs

  3. Keeping you safe by making machine tools safe

    CERN Multimedia

    2012-01-01

    CERN’s third safety objective for 2012 concerns the safety of equipment - and machine tools in particular.   There are three prerequisites for ensuring that a machine tool can be used safely: ·      the machine tool must comply with Directive 2009/104/EC, ·      the layout of the workshop must be compliant, and ·      everyone who uses the machine tool must be trained. Provided these conditions are met, the workshop head can grant authorisation to use the machine tool. To fulfil this objective, an inventory of the machine tools must be drawn up and the people responsible for them identified. The HSE Unit's Safety Inspection Service produces compliance reports for the machine tools. In order to meet the third objective set by the Director-General, the section has doubled its capacity to carry out inspections: ...

  12. The Destruction of a Safe Haven Asset?

    OpenAIRE

    Baur, Dirk G.; Kristoffer Glover

    Gold has been a store of value for centuries and a safe haven for investors in the past decades. However, the increased investment in gold for speculative or hedging purposes has changed the safe haven property. We demonstrate theoretically and empirically that investor behaviour has the potential to destroy the safe haven property of gold. The results suggest that an asset cannot be both an investment asset and an effective safe haven asset. This finding has important implications for financ...

    This paper studies monetary policy in models where multiple assets have different liquidity properties: safe and "pseudo-safe" assets coexist. A shock worsening the liquidity properties of the pseudo-safe assets raises interest-rate spreads and can cause a deep recession cum deflation. Expanding the central bank's balance sheet fills the shortage of safe assets and counteracts the recession. Lowering the interest rate on reserves insulates market interest rates from the liquidity shock and im...

  14. Thermodynamics of asymptotically safe theories

    CERN Document Server

    Rischke, Dirk H

    2015-01-01

    We investigate the thermodynamic properties of a novel class of gauge-Yukawa theories that have recently been shown to be completely asymptotically safe, because their short-distance behaviour is determined by the presence of an interacting fixed point. Not only do all the coupling constants freeze at a constant and calculable value in the ultraviolet, their values can even be made arbitrarily small for an appropriate choice of the ratio $N_c/N_f$ of fermion colours and flavours in the Veneziano limit. Thus, a perturbative treatment can be justified. We compute the pressure, entropy density, and thermal degrees of freedom of these theories to next-to-next-to-leading order in the coupling constants.

  15. How safe is Seattle's water?

    Science.gov (United States)

    1999-01-01

    According to Seattle Public Utilities, the cysts that can cause cryptosporidiosis (crypto) have been found in the city water supply periodically. Crypto can cause symptoms including diarrhea, abdominal cramps, and a low-grade fever, and can be fatal in people with CD4 counts below 200. It is very difficult to rid water of these cysts. To make sure drinking water is safe, people should boil the water for 1 to 3 minutes, depending on what altitude they are at. Also, the Centers for Disease Control suggests three methods for filtering water: microstraining with filters that remove particles smaller than one micron; reverse osmosis; and filtration with equipment that meets National Sanitation Foundation (NSF) Standard 53 for "cyst reduction". Washing hands before eating, avoiding raw or undercooked food, and wearing gloves when gardening are also ways to avoid contact with cysts. Contact information is provided. PMID:11366754

    117 consecutive herniograms were reviewed for patients who had symptoms suggestive of hernia but with no evidence or inconclusive findings on physical examination. The traditional approach has been to explore patients with suspected occult hernias. The aim of this study was to assess the impact of herniography in minimizing needless groin exploration and to evaluate its safety. Thirty-three herniograms were positive and showed unilateral and bilateral inguinal hernias. There were no false positive examinations and two false negative examinations. No complications were present. Patients with positive herniograms were explored, and operative findings correlated well with herniographic findings. Twenty-four patients were referred to other specialities. Follow-up in clinic and telephone interviews showed symptomatic improvement in the majority of patients. Herniography is useful in evaluating obscure groin pain and occult hernias. It is a safe procedure and more cost effective than a negative exploration or diagnostic laparoscopy.

  19. Safe Commits for Transactional Featherweight Java

    Science.gov (United States)

    Thuong Tran, Thi Mai; Steffen, Martin

    Transactions are a high-level alternative for low-level concurrency-control mechanisms such as locks, semaphores, monitors. A recent proposal for integrating transactional features into programming languages is Transactional Featherweight Java (TFJ), extending Featherweight Java by adding transactions. With support for nested and multi-threaded transactions, its transactional model is rather expressive. In particular, the constructs governing transactions - to start and to commit a transaction - can be used freely with a non-lexical scope. On the downside, this flexibility also allows for an incorrect use of these constructs, e.g., trying to perform a commit outside any transaction. To catch those kinds of errors, we introduce a static type and effect system for the safe use of transactions for TFJ. We prove the soundness of our type system by subject reduction.

The NSL has two main objectives: (1) improving air quality for public health; (2) offering space for and substantiating the basis for spatial projects. Chapter 3 explains the starting points and the system of the NSL. Chapter 3 provides a description of the legal framework of the NSL. Chapter 4 discusses the relation between air pollution and health and the manner in which standards were set. Chapter 5 focuses o historic and contemporary developments in emissions and concentrations of NO2 en PM10 and the projected future development of these emissions. Chapter 6 presents an extensive overview of the spatial projects that provide significant contributions to the concentrations in the open air. Chapter 7 sketches an extensive image of all measures that NSL partners commit themselves to and their effects. Chapter 8 shows that implementation of NSL throughout the Netherlands will help meet the European standards.

  4. Working safely with radioactive materials

    International Nuclear Information System (INIS)

    In common with exposure to many other laboratory chemicals, exposure to ionising radiations and to radioactive materials carries a small risk of causing harm. Because of this, there are legal limits to the amount of exposure to ionising radiations at work and special rules for working with radioactive materials. Although radiation protection is a complex subject it is possible to simplify to 10 basic things you should do -the Golden Rules. They are: 1) understand the nature of the hazard and get practical training; 2) plan ahead to minimise time spent handling radioactivity; 3) distance yourself appropriately from sources of radiation; 4) use appropriate shielding for the radiation; 5) contain radioactive materials in defined work areas; 6) wear appropriate protective clothing and dosimeters; 7) monitor the work area frequently for contamination control; 8) follow the local rules and safe ways of working; 9) minimise accumulation of waste and dispose of it by appropriate routes, and 10) after completion of work, monitor, wash, and monitor yourself again. These rules are expanded in this article. (author)

  5. Safe and green nuclear power

    International Nuclear Information System (INIS)

    Energy development plays an important role in the national economic growth. Presently the per capita consumption of energy in our country is about 750 kWh including captive power generation which is low in comparison to that in the developed countries like USA where it is about 12,000 kWh. As of now the total installed capacity of electricity generation is about 152,148 MW(e) which is drawn from Thermal (65%), Hydel (24%), Nuclear (3%) power plants and Renewables (8%). It is expected that by the end of year 2020, the required installed capacity would be more than 3,00,000 MW(e), if we assume per capita consumption of about 800-1000 kWh for Indian population of well over one billion. To meet the projected power requirement in India, suitable options need to be identified and explored for generation of electricity. For choosing better alternatives various factors such as availability of resources, potential to generate commercial power, economic viability, etc. need to be considered. Besides these factors, an important factor which must be taken into consideration is protection of environment around the operating power stations. This paper attempts to demonstrate that the nuclear power generation is an environmentally benign option for meeting the future requirement of electricity in India. It also discusses the need for creating the public awareness about the safe operations of the nuclear power plants and ionising radiation. (author)

  6. Safe Laser Beam Propagation for Interplanetary Links

    Science.gov (United States)

    Wilson, Keith E.

    2011-01-01

    Ground-to-space laser uplinks to Earth–orbiting satellites and deep space probes serve both as a beacon and an uplink command channel for deep space probes and Earth-orbiting satellites. An acquisition and tracking point design to support a high bandwidth downlink from a 20-cm optical terminal on an orbiting Mars spacecraft typically calls for 2.5 kW of 1030-nm uplink optical power in 40 micro-radians divergent beams.2 The NOHD (nominal ocular hazard distance) of the 1030nm uplink is in excess of 2E5 km, approximately half the distance to the moon. Recognizing the possible threat of high power laser uplinks to the flying public and to sensitive Earth-orbiting satellites, JPL developed a three-tiered system at its Optical Communications Telescope Laboratory (OCTL) to ensure safe laser beam propagation through navigational and near-Earth space.

  7. Prone positioning: is it safe and effective?

    Dirkes, Susan; Dickinson, Sharon; Havey, Renee; O'brien, Denise

    2012-01-01

    Prone positioning has been used as a treatment option for patients with acute lung injury or acute respiratory distress syndrome (ARDS) since the early 1970s. Prone position and extended prone position ventilation have been shown to increase end-expiratory lung volume, alveolar recruitment, and oxygenation in patients with severe hypoxemic and acute respiratory failure. Prone positioning is not a benign procedure, and there are potential risks (complications) that can occur to both the patient and the health care worker. Notable complications that can arise include: unplanned extubation, lines pulled, tubes kinked, and back and other injuries to personnel. Prone positioning is a viable, inexpensive therapy for the treatment of severe ARDS. This maneuver consistently improves systemic oxygenation in 70% to 80% of patients with ARDS. With the utilization of a standardized protocol and a trained and dedicated critical care staff, prone positioning can be performed safely. PMID:22157493

  8. Is renewable energy 100% environmentally safe

    International Nuclear Information System (INIS)

    Renewable energy (RE) concerned are usually optimistic in introducing RE as environmentally safe resource. This might be reasonably acceptable when compared with conventional energy resources, there should be some side effects however. Those effects, and critics, when considered and possibly avoided, RE sources will be environmentally more acceptable and as a result will be appreciated by consumers. In this paper we try to investigate and point out some of these critics, and negative impacts by examining examples of some RE systems and how different solutions were tackled and partially managed. Through Re resources have advantages over other resources, when environmental issues are considered, there still exists, however, some negative impacts on the environment caused by RE resources. Present study showed that the above mentioned impacts can be reduced to some reasonable level.(Author)

  9. SU-E-J-73: Extension of a Clinical OIS/EMR/R&V System to Deliver Safe and Efficient Adaptive Plan-Of-The-Day Treatments Using a Fully Customizable Plan-Library-Based Workflow

    International Nuclear Information System (INIS)

    Purpose: To extend a clinical Record and Verify (R&V) system to enable a safe and fast workflow for Plan-of-the-Day (PotD) adaptive treatments based on patient-specific plan libraries. Methods: Plan libraries for PotD adaptive treatments contain for each patient several pre-treatment generated treatment plans. They may be generated for various patient anatomies or CTV-PTV margins. For each fraction, a Cone Beam CT scan is acquired to support the selection of the plan that best fits the patient’s anatomy-of-the-day. To date, there are no commercial R&V systems that support PotD delivery strategies. Consequently, the clinical workflow requires many manual interventions. Moreover, multiple scheduled plans have a high risk of excessive dose delivery. In this work we extended a commercial R&V system (MOSAIQ) to support PotD workflows using IQ-scripting. The PotD workflow was designed after extensive risk analysis of the manual procedure, and all identified risks were incorporated as logical checks. Results: All manual PotD activities were automated. The workflow first identifies if the patient is scheduled for PotD, then performs safety checks, and continues to treatment plan selection only if no issues were found. The user selects the plan to deliver from a list of candidate plans. After plan selection, the workflow makes the treatment fields of the selected plan available for delivery by adding them to the treatment calendar. Finally, control is returned to the R&V system to commence treatment. Additional logic was added to incorporate off-line changes such as updating the plan library. After extensive testing including treatment fraction interrupts and plan-library updates during the treatment course, the workflow is running successfully in a clinical pilot, in which 35 patients have been treated since October 2014. Conclusion: We have extended a commercial R&V system for improved safety and efficiency in library-based adaptive strategies enabling a wide

  11. Safe physical human robot interaction- past, present and future

    International Nuclear Information System (INIS)

    When a robot physically interacts with a human user, the requirements should be drastically changed. The most important requirement is the safety of the human user in the sense that robot should not harm the human in any situation. During the last few years, research has been focused on various aspects of safe physical human robot interaction. This paper provides a review of the work on safe physical interaction of robotic systems sharing their workspace with human users (especially elderly people). Three distinct areas of research are identified: interaction safety assessment, interaction safety through design, and interaction safety through planning and control. The paper then highlights the current challenges and available technologies and points out future research directions for realization of a safe and dependable robotic system for human users

    2013-10-01

    Full Text Available As cloud computing becomes more and more utilized, sensitive data are being stored in cloud central servers. To ensure privacy, these data are usually encrypted before uploading, which makes searching complicated. In this paper we propose architecture of fuzzy keyword search with safe index. Bloom filter is used to build safe index which increases the searching effectiveness on a large dataset. The size of index is fixed so that the space efficiency is promoted. The experiment result shows that our searching scheme is effective and can be adapted to large encrypted file system.

  5. Combined SAFE/SNAP approach to safeguards evaluation

    International Nuclear Information System (INIS)

    Generally, the scope of a safeguards evaluation model can efficiently address one of two issues, (1) global safeguards effectiveness, or (2) vulnerability analysis for individual scenarios. The Safeguards Automated Facility Evaluation (SAFE) focuses on (1) while the Safeguards Network Analysis Procedure (SNAP) is directed at (2). SAFE addresses (1) in that it considers the entire facility, i.e., the composite system of hardware and human components, in one global analysis. SNAP addresses (2) by providing a safeguards modeling symbology sufficiently flexible to represent quite complex scenarios from the standpoint of hardware interfaces while also accounting for a rich variety of human decision making. A combined SAFE/SNAP approach to the problem of safeguards evaluation is described and illustrated through an example

  6. Capacity building in safe nanotechnologies

    International Nuclear Information System (INIS)

    In all places where engineered Nanoparticles (ENPs) are produced, used or handled, adequate workplace safety precautions should be implemented due to the protection of workers and the surrounding environment. Any possible accidental release of ENPs should be evaluated. Thereby detected potential risks have to be eliminated as far as possible. An implemented reasonable safety culture in each ENP-related company will help to meet this challenge. Different infrastructures and workplace design can help to reduce the risk of an accidentally contact of the workers with ENPs: Transferable examples will be shown from the semiconductor and life-science Industry. These systems like clean rooms, glove boxes, fume cupboards, filter and suction systems and other restricted area barrier access systems (RABS) are mainly being developed to protect sensitive products, but they can also be used to protect working personnel. Clean environments regarding airborne particulate contaminations can be classified according to ISO 14644-1. A short insight into this ISO-classification will be given. But overall, a simple and reasonable workplace and workflow organization will reduce the risk of an accidental release of ENPs largely. This may lead to a therefore necessary adaption of existing workflow patterns. The workers have to get aware about the potential risks! This can be done with appropriate education materials, leaflets, posters and brochures. These are some of the later outcomes from the NanoDevice dissemination and handbook work package.

  20. Conceptual design of inherently safe integral reactor

    Energy Technology Data Exchange (ETDEWEB)

    Kim, J. I.; Chang, M. H.; Lee, D. J. and others

    1999-03-01

    The design concept of a 300 MWt inherently safe integral reactor(ISIR) for the propulsion of extra large and superhigh speed container ship was developed in this report. The scope and contents of this report are as follows : 1. The state of the art of the technology for ship-mounted reactor 2. Design requirements for ISIR 3. Fuel and core design 4. Conceptual design of fluid system 5. Conceptual design of reactor vessel assembly and primary components 6. Performance analyses and safety analyses. Installation of two ISIRs with total thermal power of 600MWt and efficiency of 21% is capable of generating shaft power of 126,000kW which is sufficient to power a container ship of 8,000TEU with 30knot cruise speed. Larger and speedier ship can be considered by installing 4 ISIRs. Even though the ISIR was developed for ship propulsion, it can be used also for a multi-purpose nuclear power plant for electricity generation, local heating, or seawater desalination by mounting on a movable floating barge.

  1. Topological characterization of safe coordinated vehicle motions

    Energy Technology Data Exchange (ETDEWEB)

    MILGRAM.R. JAMES; KAUFMAN,STEPHEN G.

    2000-04-03

    This paper characterizes the homotopy properties and the global topology of the space of positions of vehicles which are constrained to travel without intersecting on a network of paths. The space is determined by the number of vehicles and the network. Paths in the space correspond to simultaneous non-intersecting motions of all vehicles. The authors therefore focus on computing the homotopy type of the space, and show how to do so in the general case. Understanding the homotopy type of the space is the central issue in controlling the vehicles, as it gives a complete description of the distinct ways that vehicles may move safely on the network. The authors exhibit graphs, products of graphs, and amalgamations of products of graphs that are homotopy equivalent to the full configuration space, and are far simpler than might be expected. The results indicate how a control system for such a network of vehicles (such as a fleet of automatically guided vehicles guided by wires buried in a factory floor) may be implemented.

  5. Managing Cassini Safe Mode Attitude at Saturn

    Science.gov (United States)

    Burk, Thomas A.

    2010-01-01

    The Cassini spacecraft was launched on October 15, 1997 and arrived at Saturn on June 30, 2004. It has performed detailed observations and remote sensing of Saturn, its rings, and its satellites since that time. In the event safe mode interrupts normal orbital operations, Cassini has flight software fault protection algorithms to detect, isolate, and recover to a thermally safe and commandable attitude and then wait for further instructions from the ground. But the Saturn environment is complex, and safety hazards change depending on where Cassini is in its orbital trajectory around Saturn. Selecting an appropriate safe mode attitude that insures safe operation in the Saturn environment, including keeping the star tracker field of view clear of bright bodies, while maintaining a quiescent, commandable attitude, is a significant challenge. This paper discusses the Cassini safe table management strategy and the key criteria that must be considered, especially during low altitude flybys of Titan, in deciding what spacecraft attitude should be used in the event of safe mode.

  7. International conference on safe decommissioning for nuclear activities: Assuring the safe termination of practices involving radioactive materials. Contributed papers

    International Nuclear Information System (INIS)

    Thousands of operations involving the use of radioactive substances will end during the current century. While there is considerable regulatory experience in the 'front end' of the regulatory system for practices, the experience at the back end is more limited as fewer practices have actually been terminated. When a practice is terminated because the facility has reached the end of its useful life, action has to betaken to ensure the safe shutdown of the facility and allow the removal of regulatory controls. There are many issues involved in the safe termination of practices. These include setting criteria for the release of material and sites from regulatory control; determining the suitability of the various options for decommissioning nuclear facilities, managing the waste and material released from control (recycling, reuse or disposal), and the eventual remediation of the site. Some countries have put in place regulatory infrastructures and have developed programmes to manage the associated decommissioning and remediation activities. Other countries are at the stage of assessing what is involved in terminating such practices. The purpose of this Conference is to foster an information exchange on the safe an orderly termination of practices that involve the use of radioactive substances, including both decommissioning and environmental remediation, and to promote improved coherence internationally on strategies and criteria for the safe termination of practices

  12. Program increasing of nuclear power plant safeness

    International Nuclear Information System (INIS)

    The results achieved within the project of national task 'Program increasing of nuclear power plant safeness' are presented in the document. The project was aimed to extend and deepen activities relating to safety increase of nuclear power units WWER-440 which play significant part in electricity production in the Slovak Republic. The application of advanced foreign calculating programs and calculation of radionuclide spreading in environment and techniques will influence the increase of extent, quality and international acceptance of safety analysis of nuclear power plant blocks WWER-440 and the risk valuation from operating nuclear power plants. Methodic resources for coping in emergency situation in nuclear energetics will be used for support in decision making in real time during radiation emergency on nuclear plant, region and state level. A long-term strategy in dealing with burnt fuel and radioactive substance formatting during nuclear power plant liquidation particularly with waste which is un acceptable in regional dump, has developed into a theoretical and practical preparation of solvable group for operating the converting centre Bohunice and in inactivating the nuclear power plant A-1. The diagnostic activities in nuclear power plants in the Slovak Republic have been elaborated into a project of norm documents in accordance with international norms for diagnostic systems. Presentation of new technologies and materials for repairs and reconstructions of components and nuclear power plant knots qualify increase in their reliability, safety and life. New objective methods and criterions for valuation and monitoring of the residual life and safety of fixed nuclear power plants. Results of problem solving linked with connecting the blocks of nuclear power plants to frequency regulation in electric network in the Slovak Republic are also presented in the document

  13. Safe decommissioning of units 1 and 2 of Kozloduy NPP: selection of safe enclosure time period

    International Nuclear Information System (INIS)

    The time period foreseen for Safe Enclosure is internationally varying from 30 years to 100 years. A SE period of about 70 years was considered for Kozloduy NPP, prior to start the development of 'Technical Design for the Decommissioning of Kozloduy Units 1 and 2' and detailed assessment of all factors which have influence on the SE duration. This paper shows that, on the basis of the analysis performed in the project, for safety, technological and economical reasons it is possible to reduce Kozloduy NPP SE time to 35 years. The following factors have been analysed: The radioactive decay: the surface and mass contamination acceptance criteria enabling to achieve the European Community requirements for free release level remain practically constant for a SE period .35 years. There is thus no benefit in term of decontamination factor reduction, to extend the SE period beyond 35 years. Similarly 35 years after the reactor final shut down, the . dose rate of the primary circuit will drop below 3 μSv/h and will become then negligible. From the health physics and decommissioning standpoints, there is no benefit in extending the SE period beyond 35 years. Costs and investments: After the reactor final shutdown and during the SE, some systems and equipment will remain in operation to ensure the safe conditions of the nuclear buildings: ventilation, radiation monitoring, fire protection etc. The costs associated to the maintenance and repair and in some cases to the replacement of these equipment as well as the surveillance costs will be reduced. Similarly, the costs associated to the maintenance and repair of the civil engineering structures, including their structural integrity and confining capabilities will also be reduced. The duration of SE time is also bounded to the possibilities to raise the needed funds for the decommissioning

  14. Safe Operation of Research Reactors in Germany

    International Nuclear Information System (INIS)

    In Germany, experience was gained in the field of safe operation of research reactors during the last five decades. In this time, in total 46 research reactors were built and operated safely. Concerning the design, there is, or has been, a very broad range of different types of research reactors. The variety of facilities includes large pool or tank reactors with a thermal power of several tens of megawatt as well as small educational reactors with a negligible thermal power and critical assemblies. At present, 8 research reactors are still in operation. The other facilities are permanently shutdown, in decommissioning or have already been dismantled completely and released from regulatory control. In this paper, four selected facilities still being operated are presented as examples for safe operation of research reactors in Germany, including especially a description of the safety reviews and safety upgrades for the older facilities.

  15. Inherently safe technologies-chemical and nuclear

    International Nuclear Information System (INIS)

    Probabilistic risk assessments show an inverse relationship between the likelihood and the consequences of nuclear and chemical plant accidents, but the Bhopal accident has change public complacency about the safety of chemical plants to such an extent that public confidence is now at the same low level as with nuclear plants. The nuclear industry's response was to strengthen its institutions and improve its technologies, but the public may not be convinced. One solution is to develop reactors which do not depend upon the active intervention of humans of electromechanical devices to deal with emergencies, but which have physical properties that limit the possible temperature and power of a reactor. The Process Inherent Ultimately Safe and the modular High-Temperature Gas-Cooled reactors are two possibilities. the chemical industry needs to develop its own inherently safe design precepts that incorporate smallness, safe processes, and hardening against sabotage. 5 references

    Fractal erosion of the safe basin in a Helmholtz oscillator system is studied. A linear delayed velocity feedback is employed to suppress the fractal erosion. The necessary basin erosion condition of the delayed feedback controlled system is obtained. The evolution of the boundary and area of the safe basin over time delay is also presented. It follows that the delayed velocity feedback can be used as an effective strategy to control fractal erosion of a safe basin.%Fractal erosion of the safe basin in a Helmholtz oscillator system is studied.A linear delayed velocity feedback is employed to suppress the fractal erosion.The necessary basin erosion condition of the delayed feedback controlled system is obtained.The evolution of the boundary and area of the safe basin over time delay is also presented.It follows that the delayed velocity feedback can be used as an effective strategy to control fractal erosion of a safe basin.Since the safe basin was induced to explain the integrity of dynamical systems,studies on safe basins have attracted much attention.[1-6] Leigh and Armin calculated the survival probability of a ferry in random seas by estimating the erosion of the safe basin during the ship rolling motion by using Monte Carlo simulations.[1] Lenci and Rega induced the erosion of a safe basin to explain pull-in phenomenon in micro-electro mechanical systems.[2

  4. Design strategy for control of inherently safe reactors

    International Nuclear Information System (INIS)

    Reactor power plant safety is assured through a combination of engineered barriers to radiation release (e.g., reactor containment) in combination with active reactor safety systems to shut the reactor down and remove decay heat. While not specifically identified as safety systems, the control systems responsible for continuous operation of plant subsystems are the first line of defense for mitigating radiation releases and for plant protection. ''''Inherently safe'' reactors take advantage of passive system features for decay-heat removal and reactor shutdown functions normally ascribed to active reactor safety systems. The advent of these reactors may permit restructuring of the present control system design strategy. This restructuring is based on the fact that authority for protection against unlikely accidents is, as much as practical, placed upon the passive features of the system instead of the traditional placement upon the PPS. Consequently, reactor control may be simplified, allowing the reliability of control systems to be improved and more easily defended

  5. SU-E-I-97: Smart Auto-Planning Framework in An EMR Environment (SAFEE)

    International Nuclear Information System (INIS)

    Purpose: Our Radiation Oncology Department uses clinical practice guidelines for patient treatment, including normal tissue sparing and other dosimetric constraints. These practice guidelines were adapted from national guidelines, clinical trials, literature reviews, and practitioner's own experience. Modern treatment planning systems (TPS) have the capability of incorporating these practice guidelines to automatically create radiation therapy treatment plans with little human intervention. We are developing a software infrastructure to integrate clinical practice guidelines and radiation oncology electronic medical record (EMR) system into radiation therapy treatment planning system (TPS) for auto planning. Methods: Our Smart Auto-Planning Framework in an EMR environment (SAFEE) uses a software pipeline framework to integrate practice guidelines,EMR, and TPS together. The SAFEE system starts with retrieving diagnosis information and physician's prescription from the EMR system. After approval of contouring, SAFEE will automatically create plans according to our guidelines. Based on clinical objectives, SAFEE will automatically select treatment delivery techniques (such as, 3DRT/IMRT/VMAT) and optimize plans. When necessary, SAFEE will create multiple treatment plans with different combinations of parameters. SAFEE's pipeline structure makes it very flexible to integrate various techniques, such as, Model-Base Segmentation (MBS) and plan optimization algorithms, e.g., Multi-Criteria Optimization (MCO). In addition, SAFEE uses machine learning, data mining techniques, and an integrated database to create clinical knowledgebase and then answer clinical questions, such as, how to score plan quality or how volume overlap affects physicians' decision in beam and treatment technique selection. Results: In our institution, we use Varian Aria EMR system and RayStation TPS from RaySearch, whose ScriptService API allows control by external programs. These applications are

    B2SAFE is the EUDAT service for moving and replicating data between sites and storage systems for different purposes. The goal of B2SAFE is to keep the data from a repository safe by replicating it across different geographical and administrative zones according to a set of well-defined policies. It is also a way to store large volumes of data permanently at those sites which are providing powerful on-demand data analysis facilities. In particular, B2SAFE operates on the domain of registered data where data objects are referable via persistent identifiers (PIDs). B2SAFE is more than just copying data because the PIDs must be carefully managed when data objects are moved or replicated. The EUDAT B2SAFE Service offers functionality to replicate datasets across different data centres in a safe and efficient way while maintaining all information required to easily find and query information about the replica locations. The information about the replica locations and other important information is stored in PID records, each managed in separate administrative domains. The B2SAFE Service is implemented as an iRODS module providing a set of iRODS rules or policies to interface with the EPIC handle API and uses the iRODS middleware to replicate datasets from a source data (or community) centre to a destination data centre. The definition of the dataset(s) to replicate is flexible and up to the communities using the B2SAFE service. While the B2SAFE is internally using the EPIC handle API, communities have the choice to use any PID system they prefer to assign PIDs to their digital objects. A reference to one or more EUDAT B2SAFE PIDs is returned by the B2SAFE service when a dataset is replicated. The presentation will introduce the problem space of B2SAFE, presents the achievements that have been made during the last year for enabling communities to make use of the B2SAFE service, demonstrates a EPOS use cases, outlines the commonalities and differences between the policies

    The Royal Navy requires reliable advice on the safe limits of escape from a distressed submarine (DISSUB). Flooding in a DISSUB may cause a rise in ambient pressure, increasing the risk of decompression sickness (DCS) and decreasing the maximum depth from which it is safe to escape. The aim of this study was to investigate the pressure/depth limits to escape following saturation at raised ambient pressure. Exposure to saturation pressures up to 1.6 bar (a) (160 kPa) (n = 38); escapes from depths down to 120 meters of sea water (msw) (n = 254) and a combination of saturation followed by escape (n = 90) was carried out in the QinetiQ Submarine Escape Simulator, Alverstoke, United Kingdom. Doppler ultrasound monitoring was used to judge the severity of decompression stress. The trials confirmed the previously untested advice, in the Guardbook, that if a DISSUB was lying at a depth of 90 msw, then it was safe to escape when the pressure in the DISSUB was 1.5 bar (a), but also indicated that this advice may be overly conservative. This study demonstrated that the upper DISSUB saturation pressure limit to safe escape from 90 msw was 1.6 bar (a), resulting in two cases of DCS. PMID:25109084

    We introduce a novel task execution capability that enhances the ability of in-situ crew members to function independently from Earth by enabling safe and efficient interaction with automated systems. This task execution capability provides the ability to (1) map goal-directed commands from humans into safe, compliant, automated actions, (2) quickly and safely respond to human commands and actions during task execution, and (3) specify complex motions through teaching by demonstration. Our results are applicable to future surface robotic systems, and we have demonstrated these capabilities on JPL's All-Terrain Hex-Limbed Extra-Terrestrial Explorer (ATHLETE) robot.

En 1762 sont déjà achetés plus de 180 objets scientifiques, instruments, matériaux et meubles qu’enrichissent les achats successifs qui se poursuivront en 1765, date à laquelle existe un autre inventaire. Aussi étonnant que cela paraisse, ces deux inventaires n’ont jamais été comparés, ni mis en perspective avec la liste faite lors des séquestres révolutionnaires.Ainsi ces deux inventaires successifs pour ce rare cabinet princier permettent de préciser la culture scientifique des princes grâce au choix minutieux d’objets commandés à l’abbé Nollet par l’équipe préceptorale qui enseigne aux princes. La politique d’acquisition de ces instruments donne des indications sur les pratiques scientifiques des princes. L’électricité fut-elle plus favorisée que la mécanique ou les fluides ? Quelle fut la place de l’observation de l’infiniment grand, de l’infiniment petit ? S’est-on procuré des instruments auprès d’autres constructeurs ?

  7. Software functions for safe operation - learning from Sizewell-B

    International Nuclear Information System (INIS)

    Future nuclear plants will use computer-based systems extensively. Regulatory acceptance must be planned and not underestimated. Commercial software packages will simplify it, but costly analysis and demonstration may be needed. Multiplexed control needs preparation of extensive configuration data and careful checking. On-screen soft control will need consideration of the integrity of the control path. Display design should follow human factors analysis of the operators' needs, and display layout needs great care for clarity. Computer-based system with planned quality will then bring great benefits in safe operation. (author) 1 fig., 3 refs

    Full Text Available Anthropogenic pressures on the Earth System have reached a scale where abrupt global environmental change can no longer be excluded. We propose a new approach to global sustainability in which we define planetary boundaries within which we expect that humanity can operate safely. Transgressing one or more planetary boundaries may be deleterious or even catastrophic due to the risk of crossing thresholds that will trigger non-linear, abrupt environmental change within continental- to planetary-scale systems. We have identified nine planetary boundaries and, drawing upon current scientific understanding, we propose quantifications for seven of them. These seven are climate change (CO2 concentration in the atmosphere

    A new concept of a modular nuclear reactor is presented. The neutronic-thermohydraulic calculations for the steady state design of an inherently safe reactor (RE.M.I.SE., REactor Modular Inherentemente SEguro, in Spanish) are shown here. Primary system is subdivided in several modules with individual steam generator and fuel element. Enhanced safety is attained by means of passive safety systems and inherent safety features. The total power proposed (200 Mwe) is divided in a large number of units of reduced power (2 MWth). The main parameters established from conceptual design are shown here, and also lines proposed for future steps in the design. (author)

  10. What promotes sustainability in Safe Community programmes?

    Directory of Open Access Journals (Sweden)

    Lindqvist Kent

    2009-01-01

    Full Text Available Abstract Background The theory and practice of safety promotion has traditionally focused on the safety of individuals. This study also includes systems, environments, and organizations. Safety promotion programmes are designed to support community health initiatives taking a bottom-up approach. This is a long-term and complex process. The aim of this study was to try to empirically identify factors that promote sustainability in the structures of programmes that are managed and coordinated by the local government. Methods Four focus group sessions with local government politicians and administrators in designated Safe Communities were conducted and analyzed using qualitative content analysis. Results Collaboration was found to be the basis for sustainability. Networks, enabling municipalities to exchange ideas, were reported to positively influence the programmes. Personal contacts rather than organizations themselves, determine whether collaboration is sustained. Participants reported an increase in cross-disciplinary collaboration among staff categories. Administrators and politicians were reported to collaborate well, which was perceived to speed up decision-making and thus to facilitate the programme work. Support from the politicians and the county council was seen as a prerequisite. Participants reported an increased willingness to share information between units, which, in their view, supports sustainability. A structure in which all local authorities' offices were located in close proximity to one another was considered to support collaboration. Appointing a public health coordinator responsible for the programme was seen as a way to strengthen the relational resources of the programme. Conclusion With a public health coordinator, the 'external' negotiating power was concentrated in one person. Also, the 'internal' programme strength increased when the coordination was based on a bureaucratic function rather than on one individual

    Mason, S E; Miller, R

    2001-01-01

    The need for educating patients about the dangers of unprotected sexual activity is well documented in the literature. Using clinical examples, the authors describe safe-sex strategies for patients experiencing their first episode of schizophrenia. Interventions are based on a 2-year experience of working in a hospital-based treatment and research project with 68 patients. Strategies that begin in the healing phase of schizophrenia take place in both individual and group sessions. First-episode patients are encouraged to speak explicitly about their sex-related behaviors, and HIV testing is suggested when needed. The goal of this approach is to emphasize safe-sex/HIV prevention strategies within a framework of good clinical practice. PMID:11407142

  19. Black holes and asymptotically safe gravity

    CERN Document Server

    Falls, Kevin; Raghuraman, Aarti

    2010-01-01

    Quantum gravitational corrections to black holes are studied in four and higher dimensions using a renormalisation group improvement of the metric. The quantum effects are worked out in detail for asymptotically safe gravity, where the short distance physics is characterized by a non-trivial fixed point of the gravitational coupling. We find that a weakening of gravity implies a decrease of the event horizon, and the existence of a Planck-size black hole remnant with vanishing temperature and vanishing heat capacity. The absence of curvature singularities is generic and discussed together with the conformal structure and the Penrose diagram of asymptotically safe black holes. The production cross section of mini-black holes in energetic particle collisions, such as those at the Large Hadron Collider, is analysed within low-scale quantum gravity models. Quantum gravity corrections imply that cross sections display a threshold, are suppressed in the Planckian, and reproduce the semi-classical result in the deep...

  20. Brucella suis bacteremia misidentified as Ochrobactrum anthropi by the VITEK 2 system.

    Science.gov (United States)

    2016-01-01

    Ochrobactrum and Brucella are genetically related genera of the family Brucellaceae, sharing 98.8% rRNA similarity. Because of their phenotypic similarity, Ochrobactrum can be miscoded as Brucella by automated identification systems. The misidentification on blood cultures (BCs) of B. suis as O. anthropi by the VITEK 2 system is herein described. A 67-year-old male with a prosthetic mitral valve and fever was admitted with bacteremia due to a Gram-negative coccobacillus identified as O. anthropi by VITEK 2. The patient's fever persisted along with positive blood cultures despite specific antimicrobial treatment. Due to this adverse outcome, the patient was interrogated again and admitted having domestic swine. Serological tests were positive for acute brucellosis. Polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) of BC strains identified B. suis biovar 1. Timely identification of Brucella is essential for providing proper treatment to the patient and for advising safe handling of laboratory cultures in biological safety cabinets to prevent laboratory-acquired infection. Countries where brucellosis is endemic must be aware of this possibility. PMID:27131010
