  2. 'Cabinet-safe' study of 1-8 MeV electron accelerators

    CERN Document Server

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


    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.

    Walker, Iain S.; Dickerhoff, Darryl J.; Delp, William W.


    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".

    Energy Technology Data Exchange (ETDEWEB)

    Ryu, Jeong Soo; Yoon, Doo Byung


    The HANARO SMAS(Seismic Monitoring Analysis System) is classified as Non-Nuclear Safety(NNS), seismic category I, and quality class T. It is required that this system can perform required functions, which are to preserve its structural integrity during and after an OBE or SSE. In this work, the structural integrity and seismic characteristics of the cabinet of the newly developed SMAS have been estimated. The most parts of the cabinet are identically designed with those of Yonggwhang and Gori Nuclear Power Plants(NPPs), unit 1 that successfully completed the required seismic qualification tests. The structure of the cabinet of the SMAS is manufactured by the manufacturer of the cabinet of Yonggwhang and Gori NPPs. To evaluate the seismic characteristics of the SMAS, the RRS(Required Response Spectra) of the newly developed cabinet are compared with those of Yonggwhang and Gori NPPs, unit 1. In addition, natural frequencies of the cabinet of HANARO, Yonggwhang, and Gori NPPs were measured for the comparison of the seismic characteristics of the installed cabinets. In case of HANARO, the bottom of the cabinet is welded to the base plate. The base plate is fixed to the concrete foundation by using anchor bolts. For the evaluation of the structural integrity of the welding parts and the anchor bolts, the maximum stresses and forces of the welding parts and the anchor bolts due to seismic loading are estimated. The analysis results show that maximum stresses and forces are less than the allowable limits. This new SMAS is operating at HANARO instrument room to acquire and analyze the signal of earthquake.

  20. Safe Detection System for Hydrogen Leaks

    Energy Technology Data Exchange (ETDEWEB)

    Lieberman, Robert A. [Intelligent Optical Systems, Inc., Torrance, CA (United States); Beshay, Manal [Intelligent Optical Systems, Inc., Torrance, CA (United States)


    Hydrogen is an "environmentally friendly" fuel for future transportation and other applications, since it produces only pure ("distilled") water when it is consumed. Thus, hydrogen-powered vehicles are beginning to proliferate, with the total number of such vehicles expected to rise to nearly 100,000 within the next few years. However, hydrogen is also an odorless, colorless, highly flammable gas. Because of this, there is an important need for hydrogen safety monitors that can warn of hazardous conditions in vehicles, storage facilities, and hydrogen production plants. To address this need, IOS has developed a unique intrinsically safe optical hydrogen sensing technology, and has embodied it in detector systems specifically developed for safety applications. The challenge of using light to detect a colorless substance was met by creating chemically-sensitized optical materials whose color changes in the presence of hydrogen. This reversible reaction provides a sensitive, reliable, way of detecting hydrogen and measuring its concentration using light from low-cost LEDs. Hydrogen sensors based on this material were developed in three completely different optical formats: point sensors ("optrodes"), integrated optic sensors ("optical chips"), and optical fibers ("distributed sensors") whose entire length responds to hydrogen. After comparing performance, cost, time-to-market, and relative market need for these sensor types, the project focused on designing a compact optrode-based single-point hydrogen safety monitor. The project ended with the fabrication of fifteen prototype units, and the selection of two specific markets: fuel cell enclosure monitoring, and refueling/storage safety. Final testing and development of control software for these markets await future support.

    Tahir, A.; Bansal, P.K. [Auckland Univ, (New Zealand). Dept. of Mechanical Engineering


    This paper presents the comparative experimental field performance of mechanical evaporator pressure regulating valves (MEPR) and electronic evaporator pressure regulating valves (EEPR) under the identical operating conditions of supermarket open multi-deck refrigerated display cabinets. The main goal of the supermarket refrigeration system design is to keep the displayed product at the required constant temperature, while minimising the cooling load to increase the overall energy efficiency of the system. Field tests have shown that the electronic evaporator pressure valve has a significant effect on improving the cabinet temperature and reducing the rate of frost formation on the evaporator coils with subsequent improvements in the air curtain strength.

  7. Phototherapy cabinet for ultraviolet radiation therapy

    Energy Technology Data Exchange (ETDEWEB)

    Horwitz, S.N.; Frost, P.


    A newly designed cabinet can be used for the treatment of psoriasis with fluorescent ultraviolet (UV) lamps. the new design provides more uniform distribution of UV radiation in both the horizontal and vertical axes, and several safety features have been added. The distribution and uniformity of UV output in this and in a previously described cabinet are compared. The UV output at the vertical center of the older UV light cabinet was six times greater than that at either the top or bottom, while the design of the present cabinet provides uniform UV radiation except for a slight increase at head height and at the level of the lower legs compared with the middle third of the cabinet. The variation in output of the older cabinet may, in part, explain the commonly encountered difficulty in the phototherapy of psoriasis of the scalp and lower extremities.

  11. Effects of acoustic hood on noise, CFC-11, and particulate matter in a recycling system for waste refrigerator cabinet. (United States)

    Guo, Jie; Fang, Wenxiong; Yang, Yichen; Xu, Zhenming


    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.

  13. Operationalizing safe operating space for regional social-ecological systems. (United States)

    Hossain, Md Sarwar; Dearing, John A; Eigenbrod, Felix; Johnson, Fiifi Amoako


    This study makes a first attempt to operationalize the safe operating space concept at a regional scale by considering the complex dynamics (e.g. non-linearity, feedbacks, and interactions) within a systems dynamic model (SD). We employ the model to explore eight 'what if' scenarios based on well-known challenges (e.g. climate change) and current policy debates (e.g. subsidy withdrawal). The findings show that the social-ecological system in the Bangladesh delta may move beyond a safe operating space when a withdrawal of a 50% subsidy for agriculture is combined with the effects of a 2°C temperature increase and sea level rise. Further reductions in upstream river discharge in the Ganges would push the system towards a dangerous zone once a 3.5°C temperature increase was reached. The social-ecological system in Bangladesh delta may be operated within a safe space by: 1) managing feedback (e.g. by reducing production costs) and the slow biophysical variables (e.g. temperature, rainfall) to increase the long-term resilience, 2) negotiating for transboundary water resources, and 3) revising global policies (e.g. withdrawal of subsidy) that negatively impact at regional scales. This study demonstrates how the concepts of tipping points, limits to adaptations, and boundaries for sustainable development may be defined in real world social-ecological systems.

    Martín-Gómez, César; Zapata, Omayra; Zuazua, Amaia; Villanueva, Sonia; Olaizola, Paula


    The aim of this innovative educational project is to encourage students' interest in one of the most underrated fields of architecture: building services. With this material students interact with real elements and thereby understand the relationship between facilities and the building. A set of three small technical cabinets is planned. They allow for comfortable use and movement inside the building, need minimum maintenance and are easily stored. The result is an alternative concept of a mobile laboratory called a 'technical cabinet', made up of three mobile units for fire safety, electricity and the heating/cooling system. The design, content and learning systems of the cabinets confirmed the validity of the initial concept during the first year of use. A protocol has also been developed for each of the technical cabinets so that the teaching experience may be of use in other Schools of Architecture.

Therefore the aims to ensure safe and reliable operation of the station were reached.

  17. Progress in hardware development for the SAFE heatpipe reactor system (United States)

    Ring, P. J.; Sayre, E. D.; van Dyke, Melissa; Houts, Mike


    Advanced Methods & Materials Company (AMM) previously fabricated the stainless steel modules for the SAFE 30 system. These earlier modules consisting of five fuel pins surrounding a heat pipe, were brazed together using a tricusp insert in the gaps between tubes to ensure maximum braze coverage. It was decided that if possible the next generations of modules, both stainless steel and refractory alloy, would be diffusion bonded together using a Hot Issostatic Pressing (HIP) process. This process was very successfully used in producing the bonded rhenium Nb-lZr fuel cladding and the heat exchanger for the SP-100 Nuclear Space System Ref. 1 & 2. In addition AMM have since refined the technology enabling them to produce very high temperature rocket thrust chambers. Despite this background the complex geometry required for the SAFE module was quite challenging. It was necessary to develop a method which could be applied for both stainless steel and refractory alloy systems. In addition the interstices between tubes had to be completely filled with the tricusp insert to avoid causing distortion of the tube shape during HIPing and provide thermal conductivity from the fuel tubes to the heat pipes. Nevertheless it was considered worth the effort since Hot Isostatic Pressing, if successful, will produce an assembly with the heat pipe completely embedded within the module such that the diffusion bonded assembly has the thermal conduction and strength equivalent to a solid structure. .

  18. From National Enclaves to Supporting Offices: an Analysis of the 1999 Reform of European Commissioners’ Cabinets

    Directory of Open Access Journals (Sweden)

    Renke Deckarm


    Full Text Available This article analyses the transformation of European commissioners’ private offices (cabinets from national enclaves to supporting offices. Structural changes were caused by a reform by then-Commission President Prodi in 1999. To analyse this reform, a typology based on management literature is developed. The reform is characterised as ‘big bang’: it was strategically planned by a leader, transformational and affected the entire cabinet system. The most important measures were that at least three nationalities and three Commission officials were required in cabinets. These and other measures anticipated changing demands towards cabinets caused by the 2004/7 enlargement and the Kinnock reforms. This article closes a gap in research on the Commission, in which cabinets are seldom analysed in their own right. It complements earlier evidence on change in cabinets by explaining why and how structural changes evoked a functional transformation. This contributes to the broader research agenda on change in the functioning of the Commission. Content analysis of primary sources (Prodi’s speeches and publications, expert interviews and a biographic database and recent academic publications contribute to the analysis.

  19. Towards eye-safe standoff Raman imaging systems (United States)

    Glimtoft, Martin; Bââth, Petra; Saari, Heikki; Mäkynen, Jussi; Näsilä, Antti; Östmark, Henric


    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.

    Gregorio, Eduard; Rocadenbosch, Francesc; Sanz, Ricardo; Rosell-Polo, Joan R


    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.

    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.

  3. Beam interlock system and safe machine parameters system 2010 and beyond

    CERN Document Server

    Todd, B


    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.

    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.

  7. Democracy and the Making of the President’s Cabinet in Nigeria: A Reflection of the Olusegun Obasanjo’s and Goodluck Jonathan’s Cabinets

    Directory of Open Access Journals (Sweden)

    Tunde Adeniran


    Full Text Available The Presidency, especially in Federal systems, holds peculiar and haunting fascination for scholars in their attempts to diagnose the workings of modern governments. The increasing powers of the Presidency, the recurrent debates over their use or abuse and the continuous interrogation of the extent of the legitimate use of such powers, invariably compel attention to the study of the Presidency. In Nigeria, a critical inquiry that goes beyond the surface seems to be long overdue and an appraisal of the making of a Presidential cabinet appears a vital part of the advancement of knowledge in this regard. Thus, this study is a review of democracy and the making of the presidential cabinet in Nigeria with a reflection of the Olusegun Obasanjo’s and the Goodluck Jonathan’s Cabinets. The aims are (i to investigate the role of the President as crisis manager when a nation faces serious internal security challenges; (ii to appraise the President’s role as manager of the economy – especially when fiscal and monetary policies are set in the context of double – digit inflation and severe economic dislocations; and (iii to assess the interactions between the President, the Ministries, Departments and Agencies (MDAs and the National Assembly. The study reveals among many others that for the President to be effective he needs a cabinet that fully understands what he wants to achieve, the way he wants to go about it and the time he wants to achieve it. In fact, the president needs a cabinet that shares in his vision of development for the country. Sequel to the above, the president should rely more on expertise and competence by lifting square peg into square holes.

    This study describes fail-safe mechanisms to be built in the laminated rubber base isolation devices for the purpose of developing a base isolation system necessary for the application to nuclear fuel facilities. There are two types of fail-safe devices developed in the fundamental study; a landing type on which the bottom of the building is supported and a stopper type for restricting excessive development. The basic characteristics of these devices were investigated through static and dynamic fundamental tests and input of earthquake force on a shaking table. As a result of these tests and analyses, it was proved that the whole restoring force characteristics of the two types of fail-safe devices were almost the same as expected, and their earthquake response characteristics met the initially designed performance. Moreover, it was shown that they prevent buckling of rubber bearings under input of excessive earthquake forces and consequently enhance safety of superstructures of the buildings. 4 refs., 19 figs., 1 tab.

  9. Study on the characteristic decomposition components of air-insulated switchgear cabinet under partial discharge (United States)

    Gui, Yingang; Zhang, Xiaoxing; Zhang, Ying; Qiu, Yinjun; Chen, Lincong


    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.

  14. Cyberterrorism: is the U.S. healthcare system safe? (United States)

    Harries, David; Yellowlees, Peter M


    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.

  17. Frost formation and defrost control parameters for open multideck refrigerated food display cabinets

    Energy Technology Data Exchange (ETDEWEB)

    Tassou, S.A.; Datta, D. [Brunel Univ., Dept. of Mechanical Engineering, Uxbridge (United Kingdom); Marriott, D. [Safeway Stores plc, Hayes (United Kingdom)


    In order to achieve the required air and product temperatures in refrigerated food display cabinets, the evaporator coils, which are normally located in the base of the cabinets, operate at temperatures below the freezing point of water. The air which is circulated over the evaporator coil is cooled below its dew point and water vapour present in the air condenses and eventually freezes on the coil surface. With continuous operation of the coil, frost will accumulate on the coil surface leading to a decrease both in the air flowrate and in the overall heat transfer coefficient. In order to maintain satisfactory performance, evaporator coils are defrosted periodically. Although different defrost control strategies can be employed, for simplicity and cost considerations, defrosting in supermarket refrigeration systems is usually controlled by a pre-set time cycle. It is widely acknowledge, however, that time-based defrost may cause a number of unnecessary defrost cycles and this reduces the energy efficiency of the refrigeration systems as well as the accuracy of temperature control of the cabinets. Implementing defrost only when it is needed or on 'demand' should reduce the number of defrost cycles and lead to savings in energy and improved product quality. This paper reports on field and experimental investigations on the processes of frosting and defrosting of medium-temperature display cabinet evaporator coils. The results show that for medium-temperature refrigeration applications where the environment temperature is kept reasonably constant, the store humidity is the primary parameter influencing the rate of frost formation. Using relative humidity as a control parameter the defrost frequency can be reduced considerably without affecting cabinet performance and product integrity. Alongside the effect of relative humidity, the paper also considers the effects of other performance parameters on the processes of frosting and defrosting such as cooling

  18. Eye-safe projection system with flexible architecture (United States)

    Sabirov, Viacheslav


    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.

  3. Engineering safe and secure cyber-physical systems the specification PEARL approach

    CERN Document Server

    Gumzej, Roman


    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.

    The US Department of Energy (DOE) is sponsoring SUNRAYCE 93 to advance tile technology and use of photovoltaics and electric vehicles. Participants will use cars powered by photovoltaic modules and lead-acid storage batteries. This brochure, prepared for students and faculty participating in this race, outlines the health hazards presented by these electrical systems, and gives guidance on strategies for their safe usage. At the outset, it should be noted that working with photovoltaic systems and batteries requires electric vehicle drivers and technicians to have {open_quotes}hands-on{close_quotes} contact with the car on a daily basis. It is important that no one work near a photovoltaic energy system or battery, either in a vehicle or on the bench, unless they familiarize themselves with the components in use, and know and observe safe work practices including the safety precautions described in the manuals provided by the various equipment vendors and this document.

  7. Closed supermarket refrigerator and freezer cabinets. A feasibility study

    Energy Technology Data Exchange (ETDEWEB)

    Ligthart, F.A.T.M. [ECN Energy in the Built Environment, Petten (Netherlands)


    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.

    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.

  10. The Challenge of Providing Safe Water with an Intermittently Supplied Piped Water Distribution System (United States)

    Kumpel, E.; Nelson, K. L.


    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

  11. Task-driven equipment inspection system based on safe workflow model (United States)

    Guo, Xinyou; Liu, Yangguang


    An equipment inspection system is one that contains a number of equipment queues served in cyclic order. In order to satisfy multi-task scheduling and multi-task combination requirements for equipment inspection system, we propose a model based on inspection workflow in this paper. On the one hand, the model organizes all kinds of equipments according to inspection workflow, elemental work units according to inspection tasks, combination elements according to the task defined by users. We proposed a 3-dimensional workflow model for equipments inspection system including organization sub-model, process sub-model and data sub-model. On the other hand, the model is based on the security authorization which defined by relation between roles, tasks, pre-defined business workflows and inspection data. The system based on proposed framework is safe and efficient. Our implement shows that the system is easy to operate and manage according to the basic performance.

    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

    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.

  16. Unmanned Aircraft Systems Traffic Management (UTM) Safely Enabling UAS Operations in Low-Altitude Airspace (United States)

    Kopardekar, Parimal H.


    Unmanned Aircraft System (UAS) Traffic Management (UTM) Enabling Civilian Low-Altitude Airspace and Unmanned Aircraft System Operations What is the problem? Many beneficial civilian applications of UAS have been proposed, from goods delivery and infrastructure surveillance, to search and rescue, and agricultural monitoring. Currently, there is no established infrastructure to enable and safely manage the widespread use of low-altitude airspace and UAS operations, regardless of the type of UAS. A UAS traffic management (UTM) system for low-altitude airspace may be needed, perhaps leveraging concepts from the system of roads, lanes, stop signs, rules and lights that govern vehicles on the ground today, whether the vehicles are driven by humans or are automated. What system technologies is NASA exploring? Building on its legacy of work in air traffic management for crewed aircraft, NASA is researching prototype technologies for a UAS Traffic Management (UTM) system that could develop airspace integration requirements for enabling safe, efficient low-altitude operations. While incorporating lessons learned from the today's well-established air traffic management system, which was a response that grew out of a mid-air collision over the Grand Canyon in the early days of commercial aviation, the UTM system would enable safe and efficient low-altitude airspace operations by providing services such as airspace design, corridors, dynamic geofencing, severe weather and wind avoidance, congestion management, terrain avoidance, route planning and re-routing, separation management, sequencing and spacing, and contingency management. One of the attributes of the UTM system is that it would not require human operators to monitor every vehicle continuously. The system could provide to human managers the data to make strategic decisions related to initiation, continuation, and termination of airspace operations. This approach would ensure that only authenticated UAS could operate

  17. The Importance of State and Context in Safe Interoperable Medical Systems (United States)

    Jaffe, Michael B.; Robkin, Michael; Rausch, Tracy; Arney, David; Goldman, Julian M.


    This paper describes why “device state” and “patient context” information are necessary components of device models for safe interoperability. This paper includes a discussion of the importance of describing the roles of devices with respect to interactions (including human user workflows involving devices, and device to device communication) within a system, particularly those intended for use at the point-of-care, and how this role information is communicated. In addition, it describes the importance of clinical scenarios in creating device models for interoperable devices.

  18. Wastewater treatment by a modular, domestic-scale reedbed system for safe horticultural irrigation. (United States)

    Derry, Chris; Maheshwari, Basant


    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.

  20. Clinical evaluation of semiautonomous smart wheelchair architecture (Drive-Safe System with visually impaired individuals

    Directory of Open Access Journals (Sweden)

    Vinod Sharma, PhD


    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.

  1. Imaging Flash Lidar for Safe Landing on Solar System Bodies and Spacecraft Rendezvous and Docking (United States)

    Amzajerdian, Farzin; Roback, Vincent E.; Bulyshev, Alexander E.; Brewster, Paul F.; Carrion, William A; Pierrottet, Diego F.; Hines, Glenn D.; Petway, Larry B.; Barnes, Bruce W.; Noe, Anna M.


    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.

    Droste-Franke, Bert; Kaiser, M; Schreurs, Miranda; Weber, Christoph; Ziesemer, Thomas


    Managing a successful transition of the current energy supply system to less carbon emitting options, ensuring a safe and secure supply during the whole process and in the long term, is one of the largest challenges of our time. Various approaches and first implementations show that it is not only technological issue, but also a matter of societal acceptance and acceptability, considering basic ethic values of the society. The main foci of the book are, thus, to develop an understanding about the specific challenges of the scientific policy advice in the area, to explore typical current approaches for the analysis of future energy systems and to develop criteria for the quality assessment and guidelines for the improvement of such studies. The book provides assistance to the interpretation of existing studies and guidelines for setting up and carrying out new analyses as well as for communicating and applying the results. Thereby, it aims to support the involved actors such as the respective scientific expert...

  4. Cabinet Governance and Political Stability in English Urban Councils

    Directory of Open Access Journals (Sweden)

    Stephen Greasley


    Full Text Available Policy-makers have long been concerned with the quality of local political leadership and have often resorted to institutional reform to try to improve political leadership. This paper looks at a specific and neglected facet of the political management reforms that have been implemented in English local government over the last decade: the tenure and turnover of cabinet members. The tenure of top politicians may be an important influence on the performance of local government particularly when political management is designed to favour individualised leadership. On the one hand, excessively short tenures for top politicians may damage the ability of governments to develop strategic plans and ensure they are implemented while on the other hand the risk of loss of office is central to political accountability and excessively long tenures may be indicative of an insulated and unresponsive elite. While some research attention has been paid to the tenures of leaders of councils in England there is little systematic information about the tenure of cabinet members. This paper discusses the relevance of cabinet stability and provides an overview of recent experience in England.

  5. Micro-total envelope system with silicon nanowire separator for safe carcinogenic chemistry (United States)

    Singh, Ajay K.; Ko, Dong-Hyeon; Vishwakarma, Niraj K.; Jang, Seungwook; Min, Kyoung-Ik; Kim, Dong-Pyo


    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.

  6. Scalable and fail-safe deployment of the ATLAS Distributed Data Management system Rucio

    CERN Document Server

    Lassnig, Mario; The ATLAS collaboration; Beermann, Thomas Alfons; Barisits, Martin-Stefan; Garonne, Vincent; Serfon, Cedric


    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. Every software upgrade or configuration change is thus potentially disruptive and requires fail-safe software and automatic error recovery. Rucio uses a three-layer scaling and mitigation strategy based on quasi-realtime monitoring. This strategy mainly employs independent stateless services, automatic failover, and service migration. The technologies used for deployment and mitigation include OpenStack, Puppet, Graphite, HAProxy and Apache. In this contribution, the interplay between these component, their deployment, software mitigation, and the monitoring strategy are discussed.

  8. Assessing the 'system' in safe systems-based road designs: using cognitive work analysis to evaluate intersection designs. (United States)

    Cornelissen, M; Salmon, P M; Stanton, N A; McClure, R


    While a safe systems approach has long been acknowledged as the underlying philosophy of contemporary road safety strategies, systemic applications are sparse. This article argues that systems-based methods from the discipline of Ergonomics have a key role to play in road transport design and evaluation. To demonstrate, the Cognitive Work Analysis framework was used to evaluate two road designs - a traditional Melbourne intersection and a cut-through design for future intersections based on road safety safe systems principles. The results demonstrate that, although the cut-through intersection appears different in layout from the traditional intersection, system constraints are not markedly different. Furthermore, the analyses demonstrated that redistribution of constraints in the cut-through intersection resulted in emergent behaviour, which was not anticipated and could prove problematic. Further, based on the lack of understanding of emergent behaviour, similar design induced problems are apparent across both intersections. Specifically, incompatibilities between infrastructure, vehicles and different road users were not dealt with by the proposed design changes. The importance of applying systems methods in the design and evaluation of road transport systems is discussed.

  9. Detecting Fan Faults in refrigerated Cabinets

    DEFF Research Database (Denmark)

    Thybo, C.; Rasmussen, B.D.; Izadi-Zamanabadi, Roozbeh


    Fault detection in supermarket refrigeration systems is an important topic due to both economic and food safety reasons. If faults can be detected and diagnosed before the system drifts outside the specified operational envelope, service costs can be reduced and in extreme cases the costly...... discarding of food products can be avoided. In the situations where the operational requirements can be met with a fault present, the system will operate with a higher energy consumption increasing the cost of operation. The objective of this study is to develop a robust method for detecting air circulation...

  14. Algorithm & SoC design for automotive vision systems for smart safe driving system

    CERN Document Server

    Shin, Hyunchul


    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 ...

  15. The determination of nutritional requirements for Safe Haven Food Supply System (emergency/survival foods) (United States)

    Ahmed, Selina


    The Space Station Safe Haven Food System must sustain 8 crew members under emergency conditions for 45 days. Emergency Survival Foods are defined as a nutritionally balanced collection of high density food and beverages selected to provide for the survival of Space Station flight crews in contingency situations. Since storage volume is limited, the foods should be highly concentrated. A careful study of different research findings regarding starvation and calorie restricted diets indicates that a minimum nutritional need close to RDA is an important factor for sustaining an individual's life in a stressful environment. Fat, protein, and carbohydrates are 3 energy producing nutrients which play a vital role in the growth and maintenance process of human life. A lower intake of protein can minimize the water intake, but it causes a negative nitrogen balance and a lower performance level. Other macro and micro nutrients are also required for nutritional interrelationships to metabolize the other 3 nutrients to their optimum level. The various options for longer duration than 45 days are under investigation.

  16. A fail-safe system for the ribosome under zinc-limiting conditions in Bacillus subtilis. (United States)

    Natori, Yousuke; Nanamiya, Hideaki; Akanuma, Genki; Kosono, Saori; Kudo, Toshiaki; Ochi, Kozo; Kawamura, Fujio


    As zinc is an essential trace metal ion for all living cells, cells elaborate a variety of strategies to cope with zinc starvation. In Bacillus subtilis, genes encoding ribosomal proteins L31 and S14 are duplicated into two types: one type contains a zinc-binding motif (RpmE or RpsN), whereas the other does not (YtiA or YhzA). We have previously shown that displacement of RpmE (L31) by YtiA from already assembled ribosomes is controlled by zinc, and this replacement could contribute to zinc mobilization under zinc-limiting conditions. We propose here that the switch between the two types of S14 has a different significance. rpsN is indispensable for growth and depletion of RpsN results in defective 30S subunits. YhzA can functionally replace RpsN to allow continued ribosome assembly under zinc-limiting conditions. Unlike YtiA, YhzA appeared in the ribosome at a slower rate consistent with incorporation into newly synthesized, rather than pre-existing ribosomes. These results raise the possibility that YhzA is involved in a fail-safe system for the de novo synthesis of ribosomes under zinc-limiting conditions.

  17. Active Fail-Safe Micro-Array Flow Control for Advanced Embedded Propulsion Systems (United States)

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


    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.

    Full Text Available The study is devoted to the issue of optimization of the document placement in a single RFID cabinet. It has been assumed that the optimization problem means the reduction of archivization time with respect to the information on all documents with RFID tags. Since the explicit form of the criterion function remains unknown, for the purpose of its approximation, the regression analysis method has been used. The method uses data from a computer simulation of the process of archiving data about documents. To solve the optimization problem, the modified gradient projection method has been used.

  1. Performance of indirect solar cabinet dryer

    Energy Technology Data Exchange (ETDEWEB)

    Sreekumar, A.; Manikantan, P.E.; Vijayakumar, K.P. [Solar Thermal Energy Laboratory, Department of Physics, Cochin University of Science and Technology, Kochi 682 022 (India)


    In this paper, the development and testing of a new type of efficient solar dryer, particularly meant for drying vegetables and fruit, is described. The dryer has two compartments: one for collecting solar radiation and producing thermal energy and the other for spreading the product to be dried. This arrangement was made to absorb maximum solar radiation by the absorber plate. In this dryer, the product was loaded beneath the absorber plate, which prevented the problem of discoloration due to irradiation by direct sunlight. Two axial flow fans, provided in the air inlet, can accelerate the drying rate. The dryer had six perforated trays for loading the material. The absorber plate of the dryer attained a temperature of 97.2 C when it was studied under no load conditions. The maximum air temperature in the dryer, under this condition was 78.1 C. The dryer was loaded with 4 kg of bitter gourd having an initial moisture content of 95%, and the final desired moisture content of 5% was achieved within 6 h without losing the product colour, while it was 11 h for open sun drying. The collector glazing was inclined at a particular angle, suitable to the location, for absorption of maximum solar radiation. A detailed performance analysis was done by three methods, namely 'annualized cost method', 'present worth of annual savings' and 'present worth of cumulative savings'. The drying cost for 1 kg of bitter gourd was calculated as Rs. 17.52, and it was Rs. 41.35, in the case of an electric dryer. The life span of the solar dryer was assumed to be 20 years. The cumulative present worth of annual savings over the life of the solar dryer was calculated for bitter gourd drying, and it turned out be Rs. 31659.26, which was much higher than the capital cost of the dryer (Rs. 6500). The payback period was calculated as 3.26 years, which was also very small considering the life of the system (20 years). So, the dryer would dry products free of cost

    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)

    This paper presents modeling and experimental analyses of evaporators in 'in situ' frozen-food display cabinets at low temperatures in the supermarket industry. Extensive experiments were conducted to measure store and display cabinet relative humidities and temperatures, and pressures, temperatures and mass flow rates of the refrigerant. The mathematical model adopts various empirical correlations of heat transfer coefficients and frost properties in a fin-tube heat exchanger in order to investigate the influence of indoor conditions on the performance of the display cabinets. The model is validated with the experimental data of 'in situ' cabinets. The model would be a good guide tool to the design engineers to evaluate the performance of supermarket display cabinet heat exchangers under various store conditions. (author)

  6. Flight Testing a Real-Time Hazard Detection System for Safe Lunar Landing on the Rocket-Powered Morpheus Vehicle (United States)

    Trawny, Nikolas; Huertas, Andres; Luna, Michael E.; Villalpando, Carlos Y.; Martin, Keith E.; Carson, John M.; Johnson, Andrew E.; Restrepo, Carolina; Roback, Vincent E.


    The Hazard Detection System (HDS) is a component of the ALHAT (Autonomous Landing and Hazard Avoidance Technology) sensor suite, which together provide a lander Guidance, Navigation and Control (GN&C) system with the relevant measurements necessary to enable safe precision landing under any lighting conditions. The HDS consists of a stand-alone compute element (CE), an Inertial Measurement Unit (IMU), and a gimbaled flash LIDAR sensor that are used, in real-time, to generate a Digital Elevation Map (DEM) of the landing terrain, detect candidate safe landing sites for the vehicle through Hazard Detection (HD), and generate hazard-relative navigation (HRN) measurements used for safe precision landing. Following an extensive ground and helicopter test campaign, ALHAT was integrated onto the Morpheus rocket-powered terrestrial test vehicle in March 2014. Morpheus and ALHAT then performed five successful free flights at the simulated lunar hazard field constructed at the Shuttle Landing Facility (SLF) at Kennedy Space Center, for the first time testing the full system on a lunar-like approach geometry in a relevant dynamic environment. During these flights, the HDS successfully generated DEMs, correctly identified safe landing sites and provided HRN measurements to the vehicle, marking the first autonomous landing of a NASA rocket-powered vehicle in hazardous terrain. This paper provides a brief overview of the HDS architecture and describes its in-flight performance.

  7. Scope of health systems research in Child Survival and Safe Motherhood programme. (United States)

    Dutta, P K


    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

    Wen-Ray Su


    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

    Kronland-Martinet R


    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.

  12. Encouraging resilience within SMEs: the Cabinet Office's proposed approach. (United States)

    Sterling, Stuart


    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.

  13. Detailed CFD Modelling of Open Refrigerated Display Cabinets

    Directory of Open Access Journals (Sweden)

    Pedro Dinis Gaspar


    Full Text Available A comprehensive and detailed computational fluid dynamics (CFDs modelling of air flow and heat transfer in an open refrigerated display cabinet (ORDC is performed in this study. The physical-mathematical model considers the flow through the internal ducts, across fans and evaporator, and includes the thermal response of food products. The air humidity effect and thermal radiation heat transfer between surfaces are taken into account. Experimental tests were performed to characterize the phenomena near physical extremities and to validate the numerical predictions of air temperature, relative humidity, and velocity. Numerical and experimental results comparison reveals the predictive capabilities of the computational model for the optimized conception and development of this type of equipments. Numerical predictions are used to propose geometrical and functional parametric studies that improve thermal performance of the ORDC and consequently food safety.

  14. LIBS system with compact fiber spectrometer, head mounted spectra display and hand held eye-safe erbium glass laser gun (United States)

    Myers, Michael J.; Myers, John D.; Sarracino, John T.; Hardy, Christopher R.; Guo, Baoping; Christian, Sean M.; Myers, Jeffrey A.; Roth, Franziska; Myers, Abbey G.


    LIBS (Laser Induced Breakdown Spectroscopy) systems are capable of real-time chemical analysis with little or no sample preparation. A Q-switched laser is configured such that laser induced plasma is produced on targeted material. Chemical element line spectra are created, collected and analyzed by a fiber spectrometer. Line spectra emission data is instantly viewed on a head mounted display. "Eye-safe" Class I erbium glass lasers provide for insitu LIBS applications without the need for eye-protection goggles. This is due to the fact that Megawatt peak power Q-switched lasers operating in the narrow spectral window between 1.5um and 1.6um are approximately 8000 times more "eye-safe" than other laser devices operating in the UV, visible and near infrared. In this work we construct and demonstrate a LIBS system that includes a hand held eye-safe laser gun. The laser gun is fitted with a micro-integrating sphere in-situ target interface and is designed to facilitate chemical analysis in remote locations. The laser power supply, battery pack, computer controller and spectrophotometer components are packaged into a utility belt. A head mounted display is employed for "hands free" viewing of the emitted line spectra. The system demonstrates that instant qualitative and semi-quantitative chemical analyses may be performed in remote locations utilizing lightweight commercially available system components ergonomically fitted to the operator.

  15. Design Development Test and Evaluation (DDT and E) Considerations for Safe and Reliable Human Rated Spacecraft Systems (United States)

    A team directed by the NASA Engineering and Safety Center (NESC) collected methodologies for how best to develop safe and reliable human rated systems and how to identify the drivers that provide the basis for assessing safety and reliability. The team also identified techniques, methodologies, and best practices to assure that NASA can develop safe and reliable human rated systems. The results are drawn from a wide variety of resources, from experts involved with the space program since its inception to the best-practices espoused in contemporary engineering doctrine. This report focuses on safety and reliability considerations and does not duplicate or update any existing references. Neither does it intend to replace existing standards and policy.

  16. Flow and performance of an air-curtain biological safety cabinet. (United States)

    Huang, Rong Fung; Chou, Chun I


    Using laser-assisted smoke flow visualization and tracer gas concentration detection techniques, this study examines aerodynamic flow properties and the characteristics of escape from containment, inward dispersion, and cross-cabinet contamination of a biological safety cabinet installed with an air curtain across the front aperture. The experimental method partially simulates the NSF/ANSI 49 standards with the difference that the biological tracer recommended by these standards is replaced by a mixture of 10% SF(6) in N(2). The air curtain is set up across the cabinet aperture plane by means of a narrow planar jet issued from the lower edge of the sash and a suction flow going through a suction slot installed at the front edge of the work surface. Varying the combination of jet velocity, suction flow velocity, and descending flow velocity reveals three types of characteristic flow modes: 'straight curtain', 'slightly concave curtain', and 'severely concave curtain'. Operating the cabinet in the straight curtain mode causes the air curtain to impinge on the doorsill and therefore induces serious escape from containment. In the severely concave curtain mode, drastically large inward dispersion and cross-cabinet contamination were observed because environmental air entered into the cabinet and a three-dimensional vortical flow structure formed in the cabinet. The slightly concave curtain mode presents a smooth and two-dimensional flow pattern with an air curtain separating the outside atmosphere from the inside space of the cabinet, and therefore exhibited negligibly small escape from containment, inward dispersion, and cross-cabinet contamination.

    Directory of Open Access Journals (Sweden)

    Mahmut Kaya


    Full Text Available Objectives: To evaluate the safety and efficacy of active silicone oil removal with a 23-gauge (G transconjunctival sutureless system. Materials and Methods: One hundred sixteen eyes of 113 patients who had previous retinal detachment surgery with pars plana vitrectomy and silicone oil injection surgery, and underwent silicone oil removal surgery with 23-G transconjonctival sutureless technique in our clinic between January 2009 and April 2014 were reviewed retrospectively. The patients were evaluated with regard to postoperative changes in best corrected visual acuity and intraocular pressure (IOP, and complications that occurred during and after surgery. Results: Of the 113 patients with mean age of 61.1±9.7 years (29-88 years, 62 (54.8% were males and 51 (45.2% were females. Silicone oil removal was performed 8.43±5.24 months after the initial surgery. Mean follow-up was 13.38±4.35 months. Visual acuity improved in 69 eyes (59.48%. Anatomic success was achieved in 113 eyes (97.41%. Mean IOP was 16.2±7.2 mmHg at baseline and 14.4±2.6 mmHg at postoperative day 1 (p=0.643. Eight eyes needed suturation of at least one sclerotomy. Retinal redetachment occurred in 3 eyes (2.5% resulting in a decrease in vision. There were no cases of choroidal detachment, endophthalmitis, clinically significant corneal endothelial decompensation, or macular edema. Conclusion: Active removal of 1,300-centistoke silicone oil with a 23-G transconjunctival sutureless system is a simple, sutureless technique causing minor surgical trauma. Active removal of silicone oil with the 23-G transconjunctival sutureless technique was found to be effective and safe in both phakic and pseudophakic eyes

  5. 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


    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

  6. Human-rating Automated and Robotic Systems - (How HAL Can Work Safely with Astronauts) (United States)

    Baroff, Lynn; Dischinger, Charlie; Fitts, David


    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.

  7. Angiogenic inhibitors delivered by the type III secretion system of tumor-targeting Salmonella typhimurium safely shrink tumors in mice. (United States)

    Shi, Lei; Yu, Bin; Cai, Chun-Hui; Huang, Jian-Dong


    Despite of a growing number of bacterial species that apparently exhibit intrinsic tumor-targeting properties, no bacterium is able to inhibit tumor growth completely in the immunocompetent hosts, due to its poor dissemination inside the tumors. Oxygen and inflammatory reaction form two barriers and restrain the spread of the bacteria inside the tumors. Here, we engineered a Salmonella typhimurium strain named ST8 which is safe and has limited ability to spread beyond the anaerobic regions of tumors. When injected systemically to tumor-bearing immunocompetent mice, ST8 accumulated in tumors at levels at least 100-fold greater than parental obligate anaerobic strain ST4. ST8/pSEndo harboring therapeutic plasmids encoding Endostatin fused with a secreted protein SopA could target vasculature at the tumor periphery, can stably maintain and safely deliver a therapeutic vector, release angiogenic inhibitors through a type III secretion system (T3SS) to interfere with the pro-angiogenic action of growth factors in tumors. Mice with murine CT26 colon cancer that had been injected with ST8/pSEndo showed efficient tumor suppression by inducing more severe necrosis and inhibiting blooding vessel density within tumors. Our findings provide a therapeutic platform for indirectly acting therapeutic strategies such as anti-angiogenesis and immune therapy.

  10. Advanced system model for 1574-nm imaging, scannerless, eye-safe laser radar (United States)

    Schael, Ulrich; Rothe, Hendrik


    Laser radar based on gated viewing uses narrow laser pulses to illuminate a whole scene for direct (incoherent) detection. Due to the time of flight principle and a very fast shutter with precisely controlled delay time, only light reflected in the range R (range slice ΔR) is detected by a camera. Scattered light which reaches the shutter outside a given exposure time (gate) is suppressed. Hence, it is possible to "look" along the optical axis through changing atmospheric transmissions (rain, haze, fog, snow). For each laser pulse, the grey value image ES(x,y) of the camera is captured by a framegrabber for subsequent evaluation. Image sequences from these laser radar systems are ideally suited to recognize objects, because of the automatic contrast generation of the technology. Difficult object recognition problems, detection, target tracking, or obstacle avoidance at bad weather conditions are favorite applications. In this paper we discuss improvements in the system modelling and simulation of our laser radar system. Formerly the system performance was calculated for the whole system using the signal-to-noise ratio (SNR), leading to a general estimation of the maximum range of target detection. Changing to a pixel oriented approach, we are now able to study the system response for targets with arbitrary two and even three dimensional form. We take into account different kinds of target reflectivity and the Gaussian nature of the illuminating laser spot. Hence it is possible to simulate gray value images (range slices) and calculate range images. This will lead to a modulation transfer function for the system in future. Finally, the theoretical considerations are compared with experimental results from indoor measurements.

  11. Field efficacy evaluation and post-treatment contamination risk assessment of an ultraviolet disinfection and safe storage system. (United States)

    Reygadas, Fermin; Gruber, Joshua S; Ray, Isha; Nelson, Kara L


    Inconsistent use of household water treatment and safe storage (HWTS) systems reduces their potential health benefits. Ultraviolet (UV) disinfection is more convenient than some existing HWTS systems, but it does not provide post-treatment residual disinfectant, which could leave drinking water vulnerable to recontamination. In this paper, using as-treated analyses, we report on the field efficacy of a UV disinfection system at improving household drinking water quality in rural Mexico. We further assess the risk of post-treatment contamination from the UV system, and develop a process-based model to better understand household risk factors for recontamination. This study was part of a larger cluster-randomized stepped wedge trial, and the results complement previously published population-level results of the intervention on diarrheal prevalence and water quality. Based on the presence of Escherichia coli (proportion of households with ≥ 1 E. coli/100 mL), we estimated a risk difference of -28.0% (95% confidence interval (CI): -33.9%, -22.1%) when comparing intervention to control households; -38.6% (CI: -48.9%, -28.2%) when comparing post- and pre-intervention results; and -37.1% (CI: -45.2%, -28.9%) when comparing UV disinfected water to alternatives within the household. We found substantial increases in post-treatment E. coli contamination when comparing samples from the UV system effluent (5.0%) to samples taken from the storage container (21.1%) and drinking glasses (26.0%). We found that improved household infrastructure, additional extractions from the storage container, additional time from when the storage container was filled, and increased experience of the UV system operator were associated with reductions in post-treatment contamination. Our results suggest that the UV system is efficacious at improving household water quality when used as intended. Promoting safe storage habits is essential for an effective UV system dissemination. The drinking

  12. Prehospital Ketamine is a Safe and Effective Treatment for Excited Delirium in a Community Hospital Based EMS System. (United States)

    Scaggs, Thomas R; Glass, David M; Hutchcraft, Megan Gleason; Weir, William B


    Excited delirium syndrome (ExDS) is defined by marked agitation and confusion with sympathomimetic surge and incessant physical struggle, despite futility, which may lead to profound pathophysiologic changes and sudden death. Severe metabolic derangements, including lactic acidosis, rhabdomyolysis, and hyperthermia, occur. The pathophysiology of excited delirium is a subject of ongoing basic science and clinical research. Positive associations with ExDS include male gender, mental health disorders, and substance abuse (especially sympathomimetics). Excited delirium syndrome patients often exhibit violent, psychotic behavior and have "superhuman" strength which can result in the patient fighting with police and first responders. Continued struggle can cause a patient with ExDS to experience elevated temperature (T) and acidosis which causes enzymes to fail, leading to sudden death from cardiovascular collapse and multi-system organ failure. Therefore, effective early sedation is optimal to stop this fulminant process. Treatment of ExDS must be focused on rapidly, safely, and effectively sedating the patient and providing intensive, supportive care. Benzodiazepines, like midazolam, may not be ideal to sedate ExDS patients since their onset takes several minutes, and their side effects include loss of airway control and respiratory depression. Injectable antipsychotic medications have a relatively slow onset and may cause prolongation of the QTc interval. Ketamine is the ideal medication to sedate patients with ExDS. Ketamine has a rapid, predictable onset within three to four minutes when given by intramuscular (IM) injection. It does not adversely affect airway control, breathing, heart rate, or blood pressure (BP). In this retrospective case series, prehospital scenarios in which ExDS patients received ketamine by paramedics for sedation, and their subsequent treatment in the emergency department (ED) and hospital, are described. It is demonstrated that ketamine

  13. The fail-safe system to rescue the stalled ribosomes in Escherichia coli. (United States)

    Abo, Tatsuhiko; Chadani, Yuhei


    Translation terminates at stop codon. Without stop codon, ribosome cannot terminate translation properly and reaches and stalls at the 3'-end of the mRNA lacking stop codon. Bacterial tmRNA-mediated trans-translation releases such stalled ribosome and targets the protein product to degradation by adding specific "degradation tag." Recently two alternative ribosome rescue factors, ArfA (YhdL) and ArfB (YaeJ), have been found in Escherichia coli. These three ribosome rescue systems are different each other in terms of molecular mechanism of ribosome rescue and their activity, but they are mutually related and co-operate to maintain the translation system in shape. This suggests the biological significance of ribosome rescue.

  15. Embedding 'speaking up' into systems for safe healthcare product development and marketing surveillance. (United States)

    Edwards, Brian; Hugman, Bruce; Tobin, Mary; Whalen, Matthew


    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.

  18. Project 5S: A Safe Stepping Stone into the Solar System (United States)

    Brophy, John; Culick, Fred; Dimotakis, Paul; Friedman, Louis


    The human exploration program, at least in NASA, has been directed to move beyond the Moon and travel on a flexible path into the solar system. Reaching a Near-Earth Asteroid (NEA) is a major human space flight goal but such missions have tight times and life-support requirements that require huge steps from current capabilities. An objective between the Moon and a NEA is needed. Example interim objectives are the Lagrangian points in either the Sun-Earth or Earth-Moon (EM) system. The nearest of these points beyond the Moon is E-M L2. The Lagrangian points are empty (as far as we know). As objectives for human flight,it has been argued that they suffer from a lack of public interest and of meaningful objectives for astronaut operations. To provide a physical target, a robotic spacecraft could retrieve a small NEA and bring it to a Lagrangian or other nearer-Earth point to be accessed and utilized for human-mission objectives. This paper reports on the results of a recently completed study of an asteroid retrieval mission sponsored by the Keck Institute for Space Studies (KISS) at the California Institute of Technology. The study included an evaluation of potential targets, mission objectives, mission and system design, and potential capture mechanisms. The study concluded that, while challenging, there are no fundamental show stoppers and that such a mission would be possible with technology expected to be available in this decade. The final destination selected (for safety and mission operations) was high lunar orbit. Two options for target selection are considered: (i) retrieving a small (7 meter) NEA with a mass of order 500,000 kg, and (ii) taking a similar size boulder of a large known carbonaceous NEA. Several areas of technology and program requirements were identified, but the most important conclusion was that this approach enables meeting a goal of humans going to a NEA by the mid-2020s. The advantages and benefits for human exploration are considerable

    A Faxitron sealed x-ray cabinet, operated at 100 kV, was modified to irradiate monkey testicles, to a uniform, accurately calibrated dose, for work aimed at investigating spermatogenesis in children undergoing radiotherapy. An aluminium filter was added to increase the beam quality and a lead collimating system manufactured to reduce the beam size to between 1 and 4 cm diameter. Percentage depth doses and profiles were analysed and relative in-air outputs measured with a selection of small (0.2 cc, 0.015 cc) ion chambers. The absolute calibration of the unit was carried out in a 10 x 10 cm{sup 2} beam with a 0.6 cc chamber. Backscatter factors were based on standard tables, but then modified according to experimental results with thermoluminescent dosimeters (TLD) in a phantom to account for reduced scatter in the irradiation situations. A suitable irradiation set-up was devised for the monkeys, to ensure accuracy of delivered dose to the target volume and minimize the dose to the surrounding healthy tissue. The homogeneity throughout the testes was calculated to be well within {+-}5%, using a parallel-opposed irradiation technique. The TLD measured doses to the testes on three monkeys were lower than the calculated doses by 3 to 6%. Following modifications to the standard percentage depth doses to account for changes in scatter conditions, these differences became {+-}3%. The uncertainties on both calculated and measured dose were estimated to be approximately {+-}3.2% at 1 SD.

  20. Single Party Cabinets and Presidential Democracies: insights from the Argentinean case

    Directory of Open Access Journals (Sweden)

    Marcelo CAMERLO


    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.

    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.

    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

  5. A Safe, Versatile and Translation-prone Strategy for Using Circulating Lipoproteins as Endogenous Drug Delivery Systems

    Directory of Open Access Journals (Sweden)

    Mahshid Foroozesh


    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.

  6. Study of structure of marine specialist activity in an ergative system on monitoring and managing automatic control parameters of safe navigation process

    Directory of Open Access Journals (Sweden)

    Kholichev S. N.


    Full Text Available The study of structures' common features and dynamics of the technical object tuning circuit performing automatic adjustment of safe navigation options has been conducted for the first time in the theory of ergative systems. The research of the structure and process of ergative system functioning including an automatic control system with the option of safe navigation conditions has been fulfilled. The function of signals' selection performing optimal control law reconfiguration of the mentioned system has been given, and some sequence of marine specialist activities allowing solve the problem of navigation safety has been composed. The ergative system retargeted by the ship specialist has a two-tier hierarchy. The first level is an automatic control of the safe navigation parameter, and the second is the level of reconfiguration where the ship specialist changes the parameters of regulation act. The two-level hierarchical representation of the ergative navigation security settings management system makes it possible to introduce the concept of reconfiguration of regulation level as ship specialist activity which is to reduce the uncertainty in the environment in the operation of this layer. Such a reduction can be achieved as a result of exposure to the upper level associated with ideas of the ship specialist on the regulation of safe navigation parameters of the vessel on the lower level – the level of direct control automatic safe navigation option. As a result of studying the activities of the ship specialist in the ergative system on monitoring and managing automatic control parameters of safe navigation process it has been found that the main task of the ship specialist in the operation within the ergative system ensuring the navigation safety is to monitor the input and output of the automatic control system, decisions on the choice of reconfiguration laws regulating signal on the basis of information about deviations and the

  7. Keeping health facilities safe: one way of strengthening the interaction between disease-specific programmes and health systems. (United States)

    Harries, Anthony D; Zachariah, Rony; Tayler-Smith, Katie; Schouten, Erik J; Chimbwandira, Frank; Van Damme, Wim; El-Sadr, Wafaa M


    The debate on the interaction between disease-specific programmes and health system strengthening in the last few years has intensified as experts seek to tease out common ground and find solutions and synergies to bridge the divide. Unfortunately, the debate continues to be largely academic and devoid of specificity, resulting in the issues being irrelevant to health care workers on the ground. Taking the theme 'What would entice HIV- and tuberculosis (TB)-programme managers to sit around the table on a Monday morning with health system experts', this viewpoint focuses on infection control and health facility safety as an important and highly relevant practical topic for both disease-specific programmes and health system strengthening. Our attentions, and the examples and lessons we draw on, are largely aimed at sub-Saharan Africa where the great burden of TB and HIV ⁄ AIDS resides, although the principles we outline would apply to other parts of the world as well. Health care infections, caused for example by poor hand hygiene, inadequate testing of donated blood, unsafe disposal of needles and syringes, poorly sterilized medical and surgical equipment and lack of adequate airborne infection control procedures, are responsible for a considerable burden of illness amongst patients and health care personnel, especially in resource-poor countries. Effective infection control in a district hospital requires that all the components of a health system function well: governance and stewardship, financing,infrastructure, procurement and supply chain management, human resources, health information systems, service delivery and finally supervision. We argue in this article that proper attention to infection control and an emphasis on safe health facilities is a concrete first step towards strengthening the interaction between disease-specific programmes and health systems where it really matters – for patients who are sick and for the health care workforce who provide

  8. SafeLand guidelines for landslide monitoring and early warning systems in Europe - Design and required technology (United States)

    Bazin, S.


    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

  16. Topology of sustainable management of dynamical systems with desirable states: from defining planetary boundaries to safe operating spaces in the Earth System (United States)

    Heitzig, Jobst; Kittel, Tim; Donges, Jonathan; Molkenthin, Nora


    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

  19. Influence of supermarket environmental parameters on the frosting and defrosting of vertical multideck display cabinets

    Energy Technology Data Exchange (ETDEWEB)

    Tassou, S.A.; Datta, D.


    This paper reports on results of investigations to identify and quantify the effect of in-store environmental conditions on frost accumulation on the evaporator coils of open multideck refrigerated display cabinets. Field and environmental chamber-based tests have shown that both ambient relative humidity and temperature of a store have a significant effect on the rate of frost formation on the evaporator coils, with the effect of relative humidity being much more pronounced than the effect of temperature. In supermarkets where a fixed-time defrost control strategy is employed, it is possible that cabinets are defrosted too infrequently at high relative humidities, resulting in high product temperatures, and too frequently at low relative humidities, resulting in excessive energy consumption. Considerable opportunity exists for the application of more sophisticated defrost control strategies, both to save energy and improve temperature control.

    Milczarek, Rebecca R; Avena-Mascareno, Roberto; Alonzo, Jérôme; Fichot, Mélissa I


    Photo-selective materials have been studied for their effects on the preharvest quality of horticultural crops, but little work has been done on potential postharvest processing effects. The aim of this work was to characterize the effects of 5 different photo-selective acrylic materials (used as the lid to a single-layer sun drying cabinet) on the drying rate and quality of apricots (Prunus armeniaca). Photo-selective cabinet materials that transmit light in the visible portion of the solar spectrum accelerate the apricots' drying rate in both the early period of drying and the course of drying as a whole. These materials do not significantly affect the measured quality metrics during the first day of sun drying. However, when drying is taken to completion, some minor but significant quality differences are observed. Infrared-blocking material produces dried apricot with lower red color, compared to clear, opaque black, and ultraviolet-blocking materials. Clear material produced dried apricot with significantly lower antioxidant activity, compared to black and infrared-blocking materials. Using appropriate photo-selective drying cabinet materials can reduce the required sun drying time for apricots by 1 to 2 d, compared with fully shaded drying. Ultraviolet-blocking material is recommended to maximize drying rate and minimize quality degradation.

  4. Establishment of design criteria for acceptable failure modes and fail safe considerations for the space shuttle structural system (United States)

    Westrup, R. W.


    Investigations of fatigue life, and safe-life and fail-safe design concepts as applied to space shuttle structure are summarized. The results are evaluated to select recommended structural design criteria to provide assurance that premature failure due to propagation of undetected crack-like defects will not occur during shuttle operational service. The space shuttle booster, GDC configuration B-9U, is selected as the reference vehicle. Structural elements used as basis of detail analyses include wing spar caps, vertical stabilizer skins, crew compartment skin, orbiter support frame, and propellant tank shell structure. Fatigue life analyses of structural elements are performed to define potential problem areas and establish upper limits of operating stresses. Flaw growth analyses are summarized in parametric form over a range of initial flaw types and sizes, operating stresses and service life requirements. Service life of 100 to 500 missions is considered.

  8. Safe motherhood at risk? (United States)

    Thompson, A


    Health professionals' negative attitudes toward clients often exacerbate the problems women face in terms of health status and access to health care. Thus, the health professionals can themselves be obstacles to women seeking the health care they need. A key challenge to midwives, in addition to providing technically competent services, is gaining insight into the people for whom they are responsible so that childbirth traditions are treated with respect and women are offered dignity. Safe motherhood requires intersectoral collaboration. Many innovative approaches to safe motherhood are based on the community's participation in planning services that meet the needs of women. Other approaches are based on decentralization of services. For example, a large university teaching hospital in Lusaka, Zambia, set up birthing centers around the city to take the pressure off the hospital. Midwives head up these centers, which are close to the women's homes. Decentralization of delivery services has improved the physical and emotional outcomes for mothers and newborns. Midwives must be prepared to articulate concerns about inequalities and deficiencies in the health care system in order to persuade the government to change. Women, including midwives, need to form multidisciplinary alliances to work together to effect change. The front-line workers in maternity care are midwives. They should adopt the following strategies to become even more effective in their efforts to make motherhood safer. They should listen to what women say about their needs. They should scale services to a manageable, human scale. They should learn the skills to become politically active advocates. They should work with other midwives, women, leaders, and other professional groups. Motherhood can be safe when women have more control over their own decision making, the education to liberate themselves to make their own decisions, and access to skilled care.

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

    Cary, L.; Kloppmann, W.; Battilani, A.; Bertaki, M.; Blagojevic, S.; Chartzoulakis, K.; Dalsgaard, A.; Forslund, A.; Jovanovic, Z.; Kasapakis, I.


    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.

  11. Type Safe Extensible Programming (United States)

    Chae, Wonseok


    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.

  17. Density, distribution, and genetic structure of grizzly bears in the Cabinet-Yaak Ecosystem (United States)

    Macleod, Amy C.; Boyd, Kristina L; Boulanger, John; Royle, J. Andrew; Kasworm, Wayne F.; Paetkau, David; Proctor, Michael F; Annis, Kim; Graves, Tabitha A.


    The conservation status of the 2 threatened grizzly bear (Ursus arctos) populations in the Cabinet-Yaak Ecosystem (CYE) of northern Montana and Idaho had remained unchanged since designation in 1975; however, the current demographic status of these populations was uncertain. No rigorous data on population density and distribution or analysis of recent population genetic structure were available to measure the effectiveness of conservation efforts. We used genetic detection data from hair corral, bear rub, and opportunistic sampling in traditional and spatial capture–recapture models to generate estimates of abundance and density of grizzly bears in the CYE. We calculated mean bear residency on our sampling grid from telemetry data using Huggins and Pledger models to estimate the average number of bears present and to correct our superpopulation estimates for lack of geographic closure. Estimated grizzly bear abundance (all sex and age classes) in the CYE in 2012 was 48–50 bears, approximately half the population recovery goal. Grizzly bear density in the CYE (4.3–4.5 grizzly bears/1,000 km2) was among the lowest of interior North American populations. The sizes of the Cabinet (n = 22–24) and Yaak (n = 18–22) populations were similar. Spatial models produced similar estimates of abundance and density with comparable precision without requiring radio-telemetry data to address assumptions of geographic closure. The 2 populations in the CYE were demographically and reproductively isolated from each other and the Cabinet population was highly inbred. With parentage analysis, we documented natural migrants to the Cabinet and Yaak populations by bears born to parents in the Selkirk and Northern Continental Divide populations. These events supported data from other sources suggesting that the expansion of neighboring populations may eventually help sustain the CYE populations. However, the small size, isolation, and inbreeding documented by this study

  19. An attenuated virus vaccine appears safe to the central nervous system of rainbow trout (Oncorhynchus mykiss) after intranasal delivery. (United States)

    Larragoite, Erin T; Tacchi, Luca; LaPatra, Scott E; Salinas, Irene


    Nasal vaccines are very effective but the olfactory organ provides direct access of antigens to the brain. Infectious hematopoietic necrosis virus (IHNV) is known to cause high mortalities in salmonids. The purpose of this study is to evaluate the safety of a live attenuated IHNV nasal (I.N) vaccine in rainbow trout (Oncorhynchus mykiss). In the olfactory organ, the vaccine was detected 1 and 4 days after primary I.N vaccination but not in the intramuscular (i.m) or control groups. In the brain, IHNV was detected by RT-qPCR 4 and 21 days after i.m primary vaccination. One i.m and one I.N vaccinated trout were positive at days 4 and 28 days post-boost, respectively. Presence of IHNV in the brain of i.m vaccinated fish correlated with moderate increases in IL-1β and TNF-α expression in this tissue. These results demonstrate that IHNV vaccine lasts for 4 days in the local nasal environment and that nasal vaccination appears to be safe to the CNS of rainbow trout.

  20. Perspectives of Safe Work Practices: Improving Personal Electrical Safety of Low-Voltage Systems from Electrical Hazards

    Directory of Open Access Journals (Sweden)

    Y. Mobarak,


    Full Text Available A person’s understanding of a safety hazard has a dramatic effect on his or her behavior. An in-depth understanding of a hazard usually results in a healthy respect for what can happen. People who know the most about a specific hazard tend to rely more heavily on procedures and plans to guide their actions. Personal protective equipment selection and use are influenced by increased understanding of a hazard. Training and training programs are influenced by the depth of knowledge held by all members of the line organization. Recent work has focused attention on the thermal effects of arc flashes. However, when electrical energy is converted into thermal energy in an arcing fault, still another energy conversion is taking place. Applications are on record that suggest that a considerable amount of force is created during an arcing fault. Concrete block walls can be destroyed by the increased pressure that is created during an arcing fault. This study is present about preventing injuries to people. We will study about injuries and then develop some understanding about electrical hazards. Also, we will present about safe work practices, responsible, and then about what makes us act as we do.

  3. CFD Parametric Studies for Global Performance Improvement of Open Refrigerated Display Cabinets

    Directory of Open Access Journals (Sweden)

    Pedro Dinis Gaspar


    Full Text Available A detailed CFD modelling of an open refrigerated display cabinet has been formulated in a previous study. 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.

    Full Text Available After the fall of communism in the late ’80 in Central and Eastern Europe, due to the appearance of several political parties in each state, there was the need to form coalitions in order to provide support for the governments. This paper aims to identify the institutional features that influence the coalition formation process using the rational choice institutionalism approach. In this case, the political parties, who seek to optimize their benefits in the government formation process, are constrained by the institutional environment. The institutional environment comprises the rules that determine how the governments are formed. Particularly, this paper aim is to identify how the cabinet operating rules affect the outcomes of the coalition formation process. In order to do so, I will develop a quantitative analysis of 110 cabinets in Estonia, Latvia, Lithuania, Poland, Czech Republic, Slovakia, Hungary, Slovenia, Romania and Bulgaria formed after the first free elections subsequent to the communist fall until the beginning of 2010. These countries represent the post-communist states that joined the European Union, finalizing the democratization process at least from a formal point a view. This cross-country comparison tries to explain how some institutional features influence the formation of coalitions in new democracies. This research is valuable due to the lack of this type of comparative studies on Central and Eastern European states.

  5. Vibroacoustic Analysis of a Refrigerator Freezer Cabinet Coupled with an Air Duct

    Directory of Open Access Journals (Sweden)

    Onur Çelikkan


    Full Text Available In this study, the vibration and acoustic interactions between the structure and the cavity inside the freezer cabinet were investigated. Thus, a set of numerical and experimental analyses were performed. In the numerical analysis, the acoustic characteristics of the freezer cavity were solved, and the mixed finite element method was then implemented to analyse the coupled behaviour of the cavity with the air duct using the Acoustic Fluid-Structure Interaction (AFSI technique. In the experimental analyses, an acoustic modal analysis of the freezer cavity and a structural modal analysis of the air duct were performed for the validation process. A good agreement was obtained among the results. Thus, the accuracy of the numerical model was confirmed. The validated models were used for optimizing the design. To solve the noise generation mechanism inside the freezer cabinet, the noise primarily generated by the freezer fan unit was measured under normal working conditions of the refrigerator, and the resonance frequencies were obtained. This information was compared with the normal modes of the air duct, and the overlapping frequencies were identified. To reduce the interaction between the source and the structure, a few design modifications were applied to the air duct. Thus, the structural-borne noise radiating from the air duct into the freezer cavity was reduced.

  8. Quantifying the influence of safe road systems and legal licensing age on road mortality among young adolescents: steps towards system thinking. (United States)

    Twisk, Divera; Commandeur, Jacques J F; Bos, Niels; Shope, Jean T; Kok, Gerjo


    Based on existing literature, a system thinking approach was used to set up a conceptual model on the interrelationships among the components influencing adolescent road mortality, distinguishing between components at the individual level and at the system level. At the individual level the role of risk behaviour (sometimes deliberate and sometimes from inexperience or other non-deliberate causes) in adolescent road mortality is well documented. However, little is known about the extent to which the 'road system' itself may also have an impact on younger adolescents' road mortality. This, by providing a safe or unsafe road environment for all road users (System-induced exposure) and by allowing access to high-risk vehicles at a young or older age through the legal licensing age. This study seeks to explore these relationships by analysing the extent to which the road mortality of 10 to 17 year olds in various jurisdictions can be predicted from the System-induced Exposure (SiE) in a jurisdiction and from its legal licensing age to drive motor vehicles. SiE was operationalized as the number of road fatalities per 10(5) inhabitants/all ages together, but excluding the 10 to 17 year olds. Data on road fatalities during the years 2001 through 2008 were obtained from the OECD International Road Traffic Accident Database (IRTAD) and from the USA NHTSA's Fatality Analysis Reporting System (FARS) database for 29 early and 10 late licensing jurisdictions. Linear mixed models were fitted with annual 'Adolescent road mortality per capita' for 2001 through 2008 as the dependent variable, and time-dependent 'SiE' and time-independent 'Licensing system' as predictor variables. To control for different levels of motorisation, the time-dependent variable 'Annual per capita vehicle distance travelled' was used as a covariate. Licensing system of a jurisdiction was entered as a categorical predictor variable with late licensing countries as a baseline group. The study found support

  9. 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


    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.

  11. 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 (United States)

    Cross, Jack; Schneider, John; Cariani, Pete


    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.

    Hirsch, G; Trusheim, M; Cobbs, E; Bala, M; Garner, S; Hartman, D; Isaacs, K; Lumpkin, M; Lim, R; Oye, K; Pezalla, E; Saltonstall, P; Selker, H


    The current system of biomedical innovation is unable to keep pace with scientific advancements. We propose to address this gap by reengineering innovation processes to accelerate reliable delivery of products that address unmet medical needs. Adaptive biomedical innovation (ABI) provides an integrative, strategic approach for process innovation. Although the term "ABI" is new, it encompasses fragmented "tools" that have been developed across the global pharmaceutical industry, and could accelerate the evolution of the system through more coordinated application. ABI involves bringing stakeholders together to set shared objectives, foster trust, structure decision-making, and manage expectations through rapid-cycle feedback loops that maximize product knowledge and reduce uncertainty in a continuous, adaptive, and sustainable learning healthcare system. Adaptive decision-making, a core element of ABI, provides a framework for structuring decision-making designed to manage two types of uncertainty - the maturity of scientific and clinical knowledge, and the behaviors of other critical stakeholders.

  4. Transcriptomic and metabolomic analysis of Yukon Thellungiella plants grown in cabinets and their natural habitat show phenotypic plasticity

    Directory of Open Access Journals (Sweden)

    Guevara David R


    Full Text Available Abstract Background Thellungiella salsuginea is an important model plant due to its natural tolerance to abiotic stresses including salt, cold, and water deficits. Microarray and metabolite profiling have shown that Thellungiella undergoes stress-responsive changes in transcript and organic solute abundance when grown under controlled environmental conditions. However, few reports assess the capacity of plants to display stress-responsive traits in natural habitats where concurrent stresses are the norm. Results To determine whether stress-responsive changes observed in cabinet-grown plants are recapitulated in the field, we analyzed leaf transcript and metabolic profiles of Thellungiella growing in its native Yukon habitat during two years of contrasting meteorological conditions. We found 673 genes showing differential expression between field and unstressed, chamber-grown plants. There were comparatively few overlaps between genes expressed under field and cabinet treatment-specific conditions. Only 20 of 99 drought-responsive genes were expressed both in the field during a year of low precipitation and in plants subjected to drought treatments in cabinets. There was also a general pattern of lower abundance among metabolites found in field plants relative to control or stress-treated plants in growth cabinets. Nutrient availability may explain some of the observed differences. For example, proline accumulated to high levels in cold and salt-stressed cabinet-grown plants but proline content was, by comparison, negligible in plants at a saline Yukon field site. We show that proline accumulated in a stress-responsive manner in Thellungiella plants salinized in growth cabinets and in salt-stressed seedlings when nitrogen was provided at 1.0 mM. In seedlings grown on 0.1 mM nitrogen medium, the proline content was low while carbohydrates increased. The relatively higher content of sugar-like compounds in field plants and seedlings on low nitrogen

    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.

    The U.S. Department of Energy’s Pacific Northwest National Laboratory convened the Kitchen Cabinet (KC) to facilitate a candid discussion about the role of financial institutions (FIs) in antiproliferation efforts to reduce nuclear proliferation risks by identifying suspicious business transactions and exports when making lending or insurance decisions. The meeting brought together a group of export control specialists, largely representatives from the Nuclear Suppliers Group (NSG) Participating Governments (PGs) and finance experts representing banks and insurance companies. By assembling a KC of experts, the group could understand what suspicious transactions look like from each other’s perspectives and better inform each of their operations. The goal was to develop red flags FIs could use to identify suspicious proliferation-related transactions and to help governments gain a clearer picture of proliferation using financial information.

  7. A multiple-drawer medication layout problem in automated dispensing cabinets. (United States)

    Pazour, Jennifer A; Meller, Russell D


    In this paper we investigate the problem of locating medications in automated dispensing cabinets (ADCs) to minimize human selection errors. We formulate the multiple-drawer medication layout problem and show that the problem can be formulated as a quadratic assignment problem. As a way to evaluate various medication layouts, we develop a similarity rating for medication pairs. To solve industry-sized problem instances, we develop a heuristic approach. We use hospital ADC transaction data to conduct a computational experiment to test the performance of our developed heuristics, to demonstrate how our approach can aid in ADC design trade-offs, and to illustrate the potential improvements that can be made when applying an analytical process to the multiple-drawer medication layout problem. Finally, we present conclusions and future research directions.

  8. 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


    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

  9. Wood dust and formaldehyde exposures in the cabinet-making industry. (United States)

    Sass-Kortsak, A M; Holness, D L; Pilger, C W; Nethercott, J R


    Time-weighted average (TWA) personal total and respirable dust exposures were determined gravimetrically for 48 subjects in 4 cabinet-making plants. TWA personal formaldehyde exposures also were obtained, with the use of 3M 3750 passive monitors. Selective area sampling for formaldehyde was undertaken using two methods. The results obtained with the passive monitors were compared to the standard chromotropic acid impinger method. Considerable variation was noted in the dust exposures. Cabinet-makers exposed to softwoods were found to have a mean exposure of approximately one half of the current applicable ACGIH TWA-TLV, while hard-wood exposure was twice the applicable TWA-TLV. The highest dust exposures were recorded for those workers sanding, the mean total dust being 2.91 mg/m3 (S.E. 0.70) and respirable dust 0.63 mg/m3 (S.E. 0.20). Sanding operations also were found to produce a higher proportion of respirable dust (22%) than other woodworking operations (6%-14%). Workers in assembly areas also were found to have higher dust exposures, likely reflecting the fact that conventional dust collection devices for stationary woodworking equipment are not appropriate for hand held tools and hand sanding. The importance of making respirable dust measurements is discussed. The poor correlation between paired total and respirable dust concentrations indicates that both measurements should be made. Some potential limitations to respirable wood dust sampling using 10 mm nylon cyclones are noted, however. Area dust concentrations were found to be significantly lower than personal exposures, emphasizing the importance of personal sampling data. Formaldehyde vapor exposures were very low, with a mean of 0.06 ppm (S.E. 0.01).

  10. Federal cabinet minister from N.B joins opponents to LNG terminals

    Energy Technology Data Exchange (ETDEWEB)

    Morris, C.


    This article addressed the debate regarding the United States' proposal to construct liquefied natural gas (LNG) facilities on a pristine bay between New Brunswick and Maine. Two LNG projects are currently being promoted for Passamaquoddy Bay, and 2 more proposals are expected to be announced in the near future. However, the proponents have not yet submitted any formal applications to the Canadian government. A federal cabinet minister from New Brunswick has joined the growing opposition to the proposed project, claiming that the location on the Maine side of Passamaquoddy Bay, a large inlet off the Bay of Fundy, poses too many risks to the habitat of several endangered or at-risk species, including the North Atlantic Right Whale. The proposed sites in Maine are directly across a narrow bay where tourism and fishing are prime industries in New Brunswick. The cabinet minister claims that with over 2,000 miles of coastline on the eastern seaboard, another location can be found for the LNG facilities that would not present navigational difficulties. The Canadian federal government has the jurisdiction to stop the project by not allowing the supertankers to cross Canadian waters to enter the Bay. The waters are known for their treacherous navigation. The premier of New Brunswick has also stepped in to ensure that the governor of Maine is made aware of Canada's opposition to the project. Officials with Downeast LNG and Quoddy Bay LLC claim there would not be any safety or environmental risks associated with the LNG project.

    Os odontoideum is often found incidentally. Surgical treatment is recommended for patients with atlantoaxial instability or neurologic deficits. Although various techniques have been used for C1-C2 fusion in adults, the use of these procedures in children is not widely accepted. We present a 12-year-old boy with incidental os odontoideum and obvious C1-C2 instability, in which bony union was achieved safely and successfully by posterior fixation using a rod-hook system and perioperative planning using a three-dimensional printer. At the 2-year follow-up, bone formation around the gap of the dens, which has been generally considered as pseudoarthrosis, was obtained after union of the posterior element of C1-C2.

  13. An intrinsically safe facility for forefront research and training on nuclear technologies — General description of the system (United States)

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


    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

  14. The Safe Lambda Calculus

    CERN Document Server

    Blum, William


    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 ...

  15. Voluntary certification systems in the EU wine sector: How to recognise quality and be safe from confusion

    Directory of Open Access Journals (Sweden)

    Rolandi Silvia


    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.

  16. An inducible packaging cell system for safe, efficient lentiviral vector production in the absence of HIV-1 accessory proteins. (United States)

    Pacchia, A L; Adelson, M E; Kaul, M; Ron, Y; Dougherty, J P


    Lentiviral vectors based on human immunodeficiency virus type 1 (HIV-1) possess the ability to deliver exogenous genes to both dividing and nondividing cells and to subsequently establish a stable provirus in these target cells, which can allow long-term expression of the transferred gene. Herein we describe a stable packaging cell line that is devoid of HIV-1 tat, vif, vpr, vpu, and nef. In order to avoid any risk of cytotoxicity associated with constitutive expression of HIV-1 protease or the VSV-G envelope protein, transcription of the packaging and envelope constructs was tightly controlled by employing the ecdysone-inducible system. Using this cell line, we have been able to consistently generate concentrated pseudotyped vector virus stocks with titers in the range of 10(8) IU/ml, which can efficiently transduce actively dividing and growth-arrested cells in vitro. This novel packaging cell line for lentiviral vectors facilitates the production of high-titer virus stocks in the absence of replication-competent virus and provides us with an important tool for use in future gene transfer studies.

  17. In vitro tuberization of Chlorophytum Borivilianum Sant & Fern (Safed musli) as influenced by sucrose, CCC and culture systems. (United States)

    Farshad Ashraf, Mehdi; Abd Aziz, Maheran; Abdul Kadir, Mihdzar; Stanslas, Johnson; Farokhian, Elmira


    This study focuses on the establishment of in vitro tuberization of Chlorophytum borivilianum using solid and liquid culture systems. A high in vitro tuberization rate on solid and stationary liquid Murashige and Skoog media was observed in the presence of 60 g l⁻¹ sucrose with 950, 1,265 and 1,580 µM 2-chloroethyl-trimethylammonium chloride (CCC). Application of a higher sucrose concentration of 90 g l⁻¹ showed a negative interaction with CCC on in vitro tuber number and days to in vitro tuber induction. For economic feasibility, 950 µM CCC with 60 g l⁻¹ sucrose was chosen as the best combination for in vitro tuberization in both solid and stationary liquid media. For optimization of in vitro tuber production,a comparison between solid, stationary liquid and shake liquid culture was carried out. Liquid culture with shaking at 80 r.p.m. resulted in a >2.5-fold increase in in vitro tuber production compared with solid culture.

  18. Development of optical fiber Bragg grating force-reflection sensor system of medical application for safe minimally invasive robotic surgery (United States)

    Song, Hoseok; Kim, Kiyoung; Lee, Jungju


    Force feedback plays a very important role in medical surgery. In minimally invasive surgery (MIS), however, the very long and stiff bars of surgical instruments greatly diminish force feedback for the surgeon. In the case of minimally invasive robotic surgery (MIRS), force feedback is totally eliminated. Previous researchers have reported that the absence of force feedback increased the average force magnitude applied to the tissue by at least 50%, and increased the peak force magnitude by at least a factor of two. Therefore, it is very important to provide force information in MIRS. Recently, many sensors are being developed for MIS and MIRS, but some obstacles to their application in actual medical surgery must be surmounted. The most critical problems are size limit and sterilizability. Optical fiber sensors are among the most suitable sensors for the surgical environment. The optical fiber Bragg grating (FBG) sensor, in particular, offers an important additional advantage over other optical fiber sensors in that it is not influenced by the intensity of the light source. In this paper, we present the initial results of a study on the application of a FBG sensor to measure reflected forces in MIRS environments and suggest the possibility of successful application to MIRS systems.

  20. Facilitators and Barriers to Safe Medication Administration to Hospital Inpatients: A Mixed Methods Study of Nurses' Medication Administration Processes and Systems (the MAPS Study.

    Directory of Open Access Journals (Sweden)

    Monsey McLeod

    Full Text Available Research has documented the problem of medication administration errors and their causes. However, little is known about how nurses administer medications safely or how existing systems facilitate or hinder medication administration; this represents a missed opportunity for implementation of practical, effective, and low-cost strategies to increase safety.To identify system factors that facilitate and/or hinder successful medication administration focused on three inter-related areas: nurse practices and workarounds, workflow, and interruptions and distractions.We used a mixed-methods ethnographic approach involving observational fieldwork, field notes, participant narratives, photographs, and spaghetti diagrams to identify system factors that facilitate and/or hinder successful medication administration in three inpatient wards, each from a different English NHS trust. We supplemented this with quantitative data on interruptions and distractions among other established medication safety measures.Overall, 43 nurses on 56 drug rounds were observed. We identified a median of 5.5 interruptions and 9.6 distractions per hour. We identified three interlinked themes that facilitated successful medication administration in some situations but which also acted as barriers in others: (1 system configurations and features, (2 behaviour types among nurses, and (3 patient interactions. Some system configurations and features acted as a physical constraint for parts of the drug round, however some system effects were partly dependent on nurses' inherent behaviour; we grouped these behaviours into 'task focused', and 'patient-interaction focused'. The former contributed to a more streamlined workflow with fewer interruptions while the latter seemed to empower patients to act as a defence barrier against medication errors by being: (1 an active resource of information, (2 a passive information resource, and/or (3 a 'double-checker'.We have identified practical

  1. Safe Manual Jettison (United States)

    Barton, Jay


    In space, the controlled release of certain cargoes is no less useful than the maritime jettisons from which they take their name but is also much more dangerous. Experience has shown that jettisons can be performed safely, but the process is complicated with the path to performing a jettison taking months or even years. In the background, time is also required to write procedures, train the crew, configure the vehicle, and many other activities. This paper outlines the current process used by the National Aeronautics and Space Administration (NASA) for manual jettisons, detailing the methods used to assure that the jettisons and the jettisoned objects are as safe as achievable and that the crew is adequately trained to be able to affect the safe jettison. The goal of this paper is not only to capture what it takes to perform safe jettisons in the near Earth environment but to extrapolate this knowledge to future space exploration scenarios that will likely have Extravehicular Activity (EVA) and International Partner (IP) interfaces.

  3. How should a bio-mathematical model be used within a fatigue risk management system to determine whether or not a working time arrangement is safe? (United States)

    Dawson, Drew; Darwent, David; Roach, Gregory D


    Bio-mathematical models that predict fatigue and/or sleepiness have proved a useful adjunct in the management of what has been typically referred to as fatigue-related risk. Codifying what constitutes appropriate use of these models will be increasingly important over the next decade. Current guidelines for determining a safe working time arrangement based on model outputs generally use a single upper threshold and are, arguably, over-simplistic. These guidelines fail to incorporate explicitly essential aspects of the risk assessment process - namely, the inherent uncertainty and variability in human sleep-wake behavior; the non-linear relationship between fatigue, task performance and safety outcomes; the consequence of a fatigue-related error and its influence on overall risk; and the impact of risk mitigation or controls in reducing the likelihood or consequence of a fatigue-related error. As industry and regulatory bodies increasingly move toward performance-based approaches to safety management, any fatigue risk management system that includes a bio-mathematical model should specify what exactly is measured by the model, and how the model can be used in the context of a safety management system approach. This will require significant dialog between the various parties with an interest in bio-mathematical models, i.e. developers, vendors, end-users, and regulators.

  4. Development of a safe ultraviolet camera system to enhance awareness by showing effects of UV radiation and UV protection of the skin (Conference Presentation) (United States)

    Verdaasdonk, Rudolf M.; Wedzinga, Rosaline; van Montfrans, Bibi; Stok, Mirte; Klaessens, John; van der Veen, Albert


    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)

  8. A safe and efficient hepatocyte-selective carrier system based on myristoylated preS1/21-47 domain of hepatitis B virus (United States)

    Zhang, Quan; Zhang, Xuanmiao; Chen, Tijia; Wang, Xinyi; Fu, Yao; Jin, Yun; Sun, Xun; Gong, Tao; Zhang, Zhirong


    A safe and efficient liver targeted PEGylated liposome (PEG-Lip) based on N-terminal myristoylated preS1/21-47 (preS1/21-47myr) of hepatitis B virus was successfully developed. The study aimed to elucidate the cellular uptake mechanism of preS1/21-47myr modified PEG-Lip (preS1/21-47myr-PEG-Lip) in hepatogenic cells and the distribution behavior of preS1/21-47myr-PEG-Lip in Vr:CD1 (ICR) mice. The cellular uptake results showed that preS1/21-47myr-PEG-Lip was effectively taken up by hepatogenic cells (including primary hepatocytes and liver tumor cells) through a receptor-mediated endocytosis pathway compared with non-hepatogenic cells. After systemic administration to H22 hepatoma-bearing mice, preS1/21-47myr-PEG-Lip showed significant liver-specific delivery and an increase in the distribution of preS1/21-47myr-PEG-Lip in hepatic tumor. Furthermore, the antitumor effect of preS1/21-47myr-PEG-Lip loaded with paclitaxel (PTX) was remarkably stronger than that of PTX injection and PTX loaded liposomes (including common liposomes and PEG-Lip). In safety evaluation, no acute systemic toxicity and immunotoxicity were observed after intravenous injection of preS1/21-47myr-PEG-Lip. No liver toxicity was observed despite the dramatic increase of preS1/21-47myr-PEG-Lip in liver. Taken together, preS1/21-47myr-PEG-Lip represents a promising carrier system for targeted liver disease therapy and imaging.

  9. Kokanee Stock Status and Contribution Cabinet Gorge Hatchery, Lake Pend Oreille, Idaho, 1988 Annual Progress Report.

    Energy Technology Data Exchange (ETDEWEB)

    Bowles, Edward C.


    The kokanee Oncorhynchus nerka rehabilitation program for Lake Pend Oreille continued to show progress during 1988. Estimated kokanee abundance in early September was 10.2 million fish. This estimate is 70% higher than 1987 and 140% higher than the populations's low point in 1986. Increased population size over the past two years is the result of two consecutive strong year classes produced from high recruitment of hatchery and wild fry. High recruitment of wild fry in 1988 resulted from good parental escapement (strong year class) in 1987 and relatively high fry survival. Hatchery fry made up 51% of total fry recruitment (73% of total fry biomass), which is the largest contribution since hatchery supplementation began in the 1970s. High hatchery fry abundance resulted from a large release (13 million fry) from Cabinet Gorge Hatchery and excellent fry survival (29%) during their first summer in Lake Pend Oreille. Improved fry release strategies enhanced survival, which doubled from 1987 to 1988 and was ten times higher than survival in 1986. Our research goal is to maintain 30% survival so we are very optimistic, but need to replicate additional years to address annual variability. 27 refs., 24 figs., 3 tabs.

  10. Development and evaluation of an air-curtain fume cabinet with considerations of its aerodynamics. (United States)

    Huang, R F; Wu, Y D; Chen, H D; Chen, C-C; Chen, C-W; Chang, C-P; Shih, T-S


    In order to avoid the inherent aerodynamic difficulties of the conventional fume hood, an innovative design--the 'air curtain-isolated fume hood' is developed. The new hood applies a specially designed air curtain (which is generated by a narrow planar jet and a suction slot flow at low velocities) across the sash plane. The hood constructed for the study is full size and transparent for flow visualization. The aerodynamic characteristics are diagnosed by using the laser-light-sheet-assisted smoke flow visualization method. Four characteristic air-curtain flow modes are identified in the domain of jet and suction velocities when the sash remains static. Some of these characteristic flow modes have much improved flow patterns when compared with those of the conventional fume hoods. From the viewpoint of the aerodynamics and mass transport, the results indicate that the air curtain properly setup across the sash opening allows almost no sensible exchange of momentum and mass between the flowfields of the cabinet and the outside environment. Two standard sulfur hexafluoride (SF6) tracer gas concentration measurement methods following the ANSI/ASHRAE 110-1995 standard and the prEN14175 protocol for static test are employed to examine the contaminant leakage levels. Results of the rigorous examinations of leakage show unusually satisfactory hood performance. The leakage of the tracer gas can approach almost null (<0.001 p.p.m.) if the jet and suction velocities are properly adjusted.

  11. a Cabinet Level Thermal Test Vehicle to Evaluate Hybrid Double-Sided Cooling Schemes (United States)

    Nie, Qihong; Joshi, Yogendra

    Packaging of power semiconductor devices presents some of the greatest thermal design challenges due to the resulting high heat fluxes. Advanced cooling techniques are desired to help meet these demands for current and future devices. A hybrid double-sided approach combining micro-channel liquid cooling, thermoelectric cooling, and forced air convection is investigated via a test vehicle for the thermal management of electronic cabinets. A reduction of 74% in the chip junction temperature rise was achieved by using double-sided cooling, compared to single-sided air convection. Further reduction can be achieved by utilizing thermoelectric cooling (TEC). Additional reductions of 22.4% and 6.5% were achieved by utilizing TEC in single-sided air cooling and double-sided cooling, respectively. The effect of water flow rates through the air-to-liquid heat exchanger and the microchannel heat sink on the chip junction temperature rise was insignificant, compared to the effect of TEC, and cooling configuration.

    Rhiger, Morten


    Macros still haven't made their way into typed higher-order programming languages such as Haskell and Standard ML. Therefore, to extend the expressiveness of Haskell or Standard ML, one must express new linguistic features in terms of functions that fit within the static type systems of these lan...... of these languages. This is particularly challenging when introducing features that span across multiple types and that bind variables. We address this challenge by developing, in a step by step manner, mechanisms for encoding patterns and pattern matching in Haskell in a type-safe way....

  15. Keeping food safe. (United States)

    Conde, Crystal


    Legislation passed during this year's legislative session will help the Texas Department of State Health Services (DSHS) identify the source of food-borne illness outbreaks. Senate Bill 81 increases the number of food wholesalers and warehouse operators that must obtain licenses from DSHS. DSHS enforcement activities include follow-up inspections at establishments that have problems, sending warning letters, holding management meetings with the firms, and providing technical assistance. When a food-borne illness outbreak involves a Texas manufacturer, wholesaler, or warehouse, DSHS can recall contaminated products, close establishments temporarily until they can ensure their food is safe or close them permanently, and levy fines.

  16. Curiosity's Autonomous Surface Safing Behavior Design (United States)

    Neilson, Tracy A.; Manning, Robert M.


    The safing routines on all robotic deep-space vehicles are designed to put the vehicle in a power and thermally safe configuration, enabling communication with the mission operators on Earth. Achieving this goal is made a little more difficult on Curiosity because the power requirements for the core avionics and the telecommunication equipment exceed the capability of the single power source, the Multi-Mission Radioisotope Thermoelectric Generator. This drove the system design to create an operational mode, called "sleep mode", where the vehicle turns off most of the loads in order to charge the two Li-ion batteries. The system must keep the vehicle safe from over-heat and under-heat conditions, battery cell failures, under-voltage conditions, and clock failures, both while the computer is running and while the system is sleeping. The other goal of a safing routine is to communicate. On most spacecraft, this simply involves turning on the receiver and transmitter continuously. For Curiosity, Earth is above the horizon only a part of the day for direct communication to the Earth, and the orbiter overpass opportunities only occur a few times a day. The design must robustly place the Rover in a communicable condition at the correct time. This paper discusses Curiosity's autonomous safing behavior and describes how the vehicle remains power and thermally safe while sleeping, as well as a description of how the Rover communicates with the orbiters and Earth at specific times.

  17. Controlling immune rejection is a fail-safe system against potential tumorigenicity after human iPSC-derived neural stem cell transplantation.

    Go Itakura

    Full Text Available Our previous work reported functional recovery after transplantation of mouse and human induced pluripotent stem cell-derived neural stem/progenitor cells (hiPSC-NS/PCs into rodent models of spinal cord injury (SCI. Although hiPSC-NS/PCs proved useful for the treatment of SCI, the tumorigenicity of the transplanted cells must be resolved before they can be used in clinical applications. The current study sought to determine the feasibility of ablation of the tumors formed after hiPSC-NS/PC transplantation through immunoregulation. Tumorigenic hiPSC-NS/PCs were transplanted into the intact spinal cords of immunocompetent BALB/cA mice with or without immunosuppressant treatment. In vivo bioluminescence imaging was used to evaluate the chronological survival and growth of the transplanted cells. The graft survival rate was 0% in the group without immunosuppressants versus 100% in the group with immunosuppressants. Most of the mice that received immunosuppressants exhibited hind-limb paralysis owing to tumor growth at 3 months after iPSC-NS/PC transplantation. Histological analysis showed that the tumors shared certain characteristics with low-grade gliomas rather than with teratomas. After confirming the progression of the tumors in immunosuppressed mice, the immunosuppressant agents were discontinued, resulting in the complete rejection of iPSC-NS/PC-derived masses within 42 days after drug cessation. In accordance with the tumor rejection, hind-limb motor function was recovered in all of the mice. Moreover, infiltration of microglia and lymphocytes was observed during the course of tumor rejection, along with apoptosis of iPSC-NS/PC-generated cells. Thus, immune rejection can be used as a fail-safe system against potential tumorigenicity after transplantation of iPSC-NS/PCs to treat SCI.

[Department of Radiation Oncology, University of Colorado, Aurora, Colorado (United States); Camidge, D. Ross [Department of Medical Oncology, University of Colorado, Aurora, Colorado (United States)


    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.

    随着教育的不断发展与进步,教师的作用与学生的角色已日益成为教育者与研究人员关注的焦点。但是,同时我们也应该高度重视教学课堂的重要性,努力创造一个让学生无论从心理上还是情感上都感到“安全”的教室。创造一个愉悦,友好,轻松,同时又具有很好教学效果的教学环境并不只是一种理想,笔者认为是切实可行的。本文主要探讨了如何去创造这样“安全”的教室。本文第一部分讨论了教师的形象问题,第二部分围绕师生关系展开,第三部分探讨了如何营造一种愉悦气氛,第四部分阐述了培养学生自信的重要性。%With the advancement of education ,the role of teacher and the role of learner have respectively draw increasing attention from the educators and researchers. But equal emphasis should be given to the classroom, the very place where learning takes place. And great efforts should be made to create a psychologically or emotionally safe classroom. A pleasant, friendly, relaxed but effective classroom is not something ideal as some teachers once thought, but rather practicable.This paper just discusses the ways of creating a safe classroom and gives some of my personal reflections, with Part One touching upon the image of the teacher; Part Two embracing the importance of teacher-students relationship; Part Three focusing on the pleasant climate in a safe classroom; Part Four featuring the student’s high-self-esteem.

    Full Text Available Objectives: This study aimed to validate the use of peracetic acid as sporicide agent to decontaminate the workingsurface of a laminar flow biological safety cabinet (BSC, as an alternative to glutaraldehyde, including the selection ofthe disinfecting agent, the method of application, and the contact time.Materials and methods: The test organism was the spore-forming bacterium Bacillus atrophaeus ATCC 9372, which isa surrogate for an important infectious agent. Spore cultures were prepared from B. atrophaeus and used them to testthe sporicidal efficacy of peracetic acid on a BSC stainless steel surface. The performance of the sterilant was assessedby determining minimal inhibitory concentration (MIC and by microbial challenge in conditions that mimicked surfacecontamination. It was used 2.0% glutaraldehyde solution as the control.Results: The range of MICs was 0.6-1.1% for the control and 0.003-0.006% for the 0.2% peracetic acid solution. The 0.2%peracetic acid was an effective sterilant against B. atrophaeus spores (6-7 log spores, under defined conditions of useafter 40 min contact time, which was double that recommended on the product label.Conclusion: It was conclude that while the results of official methods can help to evaluate how products will perform,they are not usually reproducible in real-life user conditions and environments. Validation tests must be carried out toensure the efficacy and safety of surface decontamination procedures.

    Think of CERN and you’ll probably think of particle accelerators and detectors. These are the tools of the trade in particle physics, but behind them are the racks of electronics that include power supplies, control systems and data acquisition networks.   Inside an electronics rack: danger could be lurking if the rack is not powered off. In routine operation, these are no more harmful than the home entertainment system in your living room. But unscrew the cover and it’s a different matter. Even after following appropriate training, and with formal authorisation from your group leader or equivalent to carry out electrical work or any work in the vicinity of electrical hazards, and even with extensive experience of carrying out such operations, it’s important to incorporate safe working practices into your routine. At CERN, before the racks of electronics reach their operational configurations for the accelerators and detectors, they play a vital role in test set-ups ...

  7. Safety of Hydrogen Systems Installed in Outdoor Enclosures

    Energy Technology Data Exchange (ETDEWEB)

    Barilo, Nick F.


    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

  8. A Carboniferous Cabinet of Wonders: an example of how the collaboration of art and Earth Sciences can inspire conservation (United States)

    Grey, Melissa; Rogers, Janine


    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

  11. Safe Exploration in Markov Decision Processes

    CERN Document Server

    Moldovan, Teodor Mihai


    In environments with uncertain dynamics exploration is necessary to learn how to perform well. Existing reinforcement learning algorithms provide strong exploration guarantees, but they tend to rely on an ergodicity assumption. The essence of ergodicity is that any state is eventually reachable from any other state by following a suitable policy. This assumption allows for exploration algorithms that operate by simply favoring states that have rarely been visited before. For most physical systems this assumption is impractical as the systems would break before any reasonable exploration has taken place, i.e., most physical systems don't satisfy the ergodicity assumption. In this paper we address the need for safe exploration methods in Markov decision processes. We first propose a general formulation of safety through ergodicity. We show that imposing safety by restricting attention to the resulting set of guaranteed safe policies is NP-hard. We then present an efficient algorithm for guaranteed safe, but pot...

  12. Aflatoxins & Safe Storage

    Directory of Open Access Journals (Sweden)

    Philippe eVillers


    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.

    This paper reports a performance test of a full-size soft-landing fail-safe (SL) device developed as a back-up device of a laminated rubber vibration absorbing equipment. It is supposed that an SL device with a symmetrical shape relative to the center axis and a vibration absorbing equipment are installed in such a manner that the former is surrounded adjacently by the latter, and an excessive horizontal force is applied to an upper building supported on the laminated rubber plates. Since the laminated rubber plates displace in the horizontal direction and subside at the same time, the upper building slides in contact with the sliding face on top of the SL device. The upper building is, therefore, supported stably by the SL device even if the load supporting capability of the rubber plates has decreased. Standard and high-decay laminated rubber plates have been used for the vibration absorbing equipment, and super-high molecular polyethylene as the material for the SL sliding face. A dynamic characteristic test on assembly of laminated rubber with the SL device, and a large-deformation horizontal force application test have confirmed that the SL device functions effectively as a back-up device for the vibration absorbing equipment. 5 refs., 14 figs.

  14. Kokanee Stock Status and Contribution of Cabinet Gorge Hatchery, Lake Pend Oreille, Idaho, Final Report.

    Energy Technology Data Exchange (ETDEWEB)

    Paragamian, Vaugh L.


    Lake Pend Oreille once provided the most popular kokanee Oncorhynchus nerka fishery in northern Idaho. A dramatic decline in the population occurred from the mid-1960s to 1970s. Restoration efforts included construction of the Cabinet Gorge Fish Hatchery to supplement the wild population and restore the fishery. In this study, hatchery-reared age 0 kokanee were stocked into Lake Pend Oreille from 1986 through 1992. Seven experimental stocking strategies for kokanee were tested using five locations and two time periods (early May through early June or late July). In 1985, the age 3 and older kokanee totaled about 0.35 million, but rose to 0.78 million in 1986, was stable, was then followed by a decline in 1990 to 0.53 million, then improved to 1.75 million in 1992. Much of the annual variation in total numbers of kokanee, ranging from 4.5 million to 10.2 million, was due to hatchery stockings of age 0 fish. Standing stocks of kokanee remained stable and ranged from 8 to 10 kg/hectare de spite dramatic changes in density due to age 0 fish. Prior to this study (1985), standing stocks were substantially higher (mean = 13.6 kg/hectare), indicating that the population may be operating below carrying capacity. The authors found survival of age 0 hatchery kokanee by each release season to range from 3% in 1986 to 39% in 1992, while the mean from 1987 through 1992 was 23%. They found significant (P=0.05) differences in survival between years, but they could not detect differences between stocking locations (P>0.71). Their analysis of survival between time (early vs late) and location was weak and inconclusive because after 1989 they had fewer fish to stock and could not repeat testing of some release strategies. They believe some of the variation in survival between release groups each year was due to the length of time between release in the lake and trawling.

    Hoelscher, Brian


    The kokanee Oncorhynchus nerka rehabilitation program for Lake Pend Oreille continued to show progress during 1989. Estimated kokanee abundance in late August was 7.71 million fish. Decreased population size is the result of lower hatchery and wild fry recruitment and low age 1+ survival. Lower recruitment of wild fry in 1989 resulted from a smaller parental escapement in 1988 and lower wild fry survival. Six fry release strategies were evaluated in 1989. Two groups were released in Clark Fork River to help improve a spawning run to Cabinet Gorge Hatchery. Survival from the mid-summer release, which was barged down Clark Fork River to avoid low flow problems, was not significantly different from the early release. The final assessment of these release strategies will be evaluated when adults return to Cabinet gorge Hatchery in 1992 and 1993. Fry released to support the Sullivan Springs Creek spawning run also survived will in 1989. Two open-water releases were made during early and mid-summer. 30 refs., 26 figs., 2 tabs.

  19. Bake-Out Mobile Controls for Large Vacuum Systems

    CERN Document Server

    Blanchard, S; Gomes, P; Pereira, H; Kopylov, L; Merker, S; Mikheev, M


    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

  6. Effect of the Panel Type and Panel Thickness on Moment Resistance of Screw-Jointed Corner Joints and Stiffness of Four-Member Cabinets

    Directory of Open Access Journals (Sweden)

    Mehmet Yuksel


    Full Text Available The objective of this study was to investigate the effects of panel type and panel thickness on moment resistance of L-type corner joints and deflection characteristics of four-member cabinets. Three different wood based panels, namely particleboard (PB, medium density fiberboard (MDF, and okoume (Aucoumea klaineana plywood (PW were utilized in two different thickness levels for constructing the four-member cabinets. All corner joints and cases were assembled with 4 x 50 mm screws without adhesive. The four member cabinets were tested under static load by supporting at three points. Furthermore, moment resistances of the same type jointed L-type corner joints were tested under static compression and tension loads. Test results indicated that the highest stiffness values were observed with 15 mm PW. This showed that 15 mm plywood could be used instead of 18 mm PW. 16 mm PB and MDF cabinets yielded higher stiffness values than those of 18 mm MDF, PW, and PB. Test results also indicated that 15 mm and 16 mm thick panels can have nearly the same stiffness as 18 mm thick panel.

  7. Use of UV-C radiation to disinfect non-critical patient care items: a laboratory assessment of the Nanoclave Cabinet

    Moore Ginny


    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

  10. An artificial neural network to safely reduce the number of ambulance ECGs transmitted for physician assessment in a system with prehospital detection of ST elevation myocardial infarction

    Directory of Open Access Journals (Sweden)

    Forberg Jakob L


    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.

  11. Optimization and investigation of the effect of velocity distribution of air curtains on the performance of food refrigerated display cabinets (United States)

    Wu, XueHong; Chang, ZhiJuan; Ma, QiuYang; Lu, YanLi; Yin, XueMei


    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.

  16. Kokanee Stock Status and Contribution of Cabinet Gorge Hatchery, Lake Pend Oreille, Idaho, 1987 Annual Progress Report.

    Energy Technology Data Exchange (ETDEWEB)

    Bowles, Edward C.


    Estimated kokanee Oncorhynchus nerka abundance in Lake Pend Oreille was 6.01 million during late summer 1987. This estimate is 40% higher than the 1986 estimate and is the second largest population estimate since 1977. Higher abundance is predominantly a result of enhanced fry survival and recruitment. Hatchery-reared fry contribution was 22% of total fry recruitment in 1987, compared to 8% in 1986, and resulted from a fivefold increase in survival. Much of this improvement can be attributed to the large (52 mm) fry produced at Cabinet Gorge Hatchery in 1987 and represents the first measurable contribution of the new hatchery to the kokanee rehabilitation program. Survival of hatchery-reared fry released into Clark Fork River was nearly one-half that of fry released into Sullivan Springs due to poor flow conditions and potentially high predation during migration from Cabinet Gorge Hatchery to Lake Pend Oreille. Wild fry survival was enhanced by early availability of forage (cladocern zooplankton) during fry emergence in late spring. Cladoceran production began three weeks earlier in 1987 than 1986, which resulted from reduced Mysis abundance and earlier thermal stratification of Lake Pend Oreille, which helped segregate cladocerans from mysid predation. Kokanee dry otolith coding was evaluated to provide a reliable long-term mark. Analysis of daily growth increments on otoliths was used successfully in 1987 to differentiate fry from various release sites. The technique will be refined during 1988 to include coding fry otoliths with water temperature fluctuations during hatchery residence. 23 refs., 20 figs., 2 tabs.

    Mwabi, J. K.; Adeyemo, F. E.; Mahlangu, T. O.; Mamba, B. B.; Brouckaert, B. M.; Swartz, C. D.; Offringa, G.; Mpenyana-Monyatsi, L.; Momba, M. N. B.

    One of the United Nations Millennium Development Goals is to reduce to half by 2015 the number of people, worldwide, who lack access to safe water. Due to the numerous deaths and illnesses caused by waterborne pathogens, various household water treatment devices and safe storage technologies have been developed to treat and manage water at the household level. The new approaches that are continually being examined need to be durable, lower in overall cost and more effective in the removal of the contaminants. In this study, an extensive literature survey was conducted to regroup various household treatment devices that are suitable for the inexpensive treatment of water on a household basis. The survey has resulted in the selection of four household treatment devices: the biosand filter (BSF), bucket filter (BF), ceramic candle filter (CCF) and the silver-impregnated porous pot filter (SIPP). The first three filters were manufactured in a Tshwane University of Technology workshop, using modified designs reported in literature. The SIPP filter is a product of the Tshwane University of Technology. The performance of the four filters was evaluated in terms of flow rate, physicochemical contaminant (turbidity, fluorides, phosphates, chlorophyll a, magnesium, calcium and nitrates) and microbial contaminant ( Escherichia coli, Vibrio cholerae, Salmonella typhimurium, Shigella dysenteriae) removals. The flow rates obtained during the study period were within the recommended limits (171 l/h, 167 l/h, 6.4 l/h and 3.5 l/h for the BSF, BF, CCF and SIPP, respectively). Using standard methods, the results of the preliminary laboratory and field studies with spiked and environmental water samples indicated that all filters decreased the concentrations of contaminants in test water sources. The most efficiently removed chemical contaminant in spiked water was fluoride (99.9%) and the poorest removal efficiency was noted for magnesium (26-56%). A higher performance in chemical

    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.

  16. Development of a Prototype Web GIS-Based Disaster Management System for Safe Operation of the Next Generation Bimodal Tram, South Korea—Focused Flooding and Snowfall

    Directory of Open Access Journals (Sweden)

    Won Seok Jang


    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.

  19. How to Safely Integrate Multiple Applications on Embedded Many-Core Systems by Applying the “Correctness by Construction” Principle

    Directory of Open Access Journals (Sweden)

    Robert Hilbrich


    Full Text Available Software-intensive embedded systems, especially cyber-physical systems, benefit from the additional performance and the small power envelope offered by many-core processors. Nevertheless, the adoption of a massively parallel processor architecture in the embedded domain is still challenging. The integration of multiple and potentially parallel functions on a chip—instead of just a single function—makes best use of the resources offered. However, this multifunction approach leads to new technical and nontechnical challenges during the integration. This is especially the case for a distributed system architecture, which is subject to specific safety considerations. In this paper, it is argued that these challenges cannot be effectively addressed with traditional engineering approaches. Instead, the application of the “correctness by construction” principle is proposed to improve the integration process.

    Energy Technology Data Exchange (ETDEWEB)

    Drenckhahn, W.; Hassmann, K.; Kuehne, H.M.


    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.)

  4. 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.


    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.

  5. Kokanee Stock Status and Contribution of Cabinet Gorge Hatchery, Lake Pend Oreille, Idaho, 1986 Annual Progress Report.

    Energy Technology Data Exchange (ETDEWEB)

    Bowles, Edward C.


    Estimated kokanee (Oncorhynchus nerka) abundance in Lake Pend Oreille was 4.3 million during September 1986. This estimate was similar to 1985 and indicates continued suppression of the kokanee population since initial decline in the late 1960s. Atypically high survival of wild fry resulted in similar fry recruitment in 1986 as 1985, whereas hatchery-reared fry contributed only 8% to total fry recruitment as a result of low post-release survival (3%). Fry released into the Clark Fork River from Cabinet Gorge Hatchery had very low survival during emigration to Lake Pend Oreille, resulting from poor flow conditions and potentially high predation. Fry survival during emigration was twice as high during nighttime flows of 16,000 cfs than 7,800 cfs. Emigration also was faster during higher flows. Several marks were tested to differentially mark fry release groups to help determine impacts of flow and other factors on fry survival. Survival of fry marked with tetracycline and fluorescent dye was high (>99%) during the 10-week study. In contrast, survival of fry marked with fluorescent grit marks ranged from 5 to 93%, depending on application pressure and distance from the fry. Retention was high (>96%) for tetracycline and grit marks during the study, whereas dye marks were discernible (100%) for only one week. 23 refs., 20 figs., 10 tabs.

  8. Safe abortion: a woman's right. (United States)

    Sangala, Vanessa


    Complications of induced abortion sadly remain significant causes of maternal mortality and morbidity around the world, but only in countries that do not provide access to safe abortion services. This article presents a brief account of how high maternal mortality from induced abortion became history in the UK and the dire consequences to women's health that unsafe abortion still has in many countries of the world. It gives a brief overview of the methods available to evacuate the uterus, with particular reference to manual vacuum aspiration. The status of the law in different countries is discussed, together with the need for health professionals to interpret repressive laws in ways that enables them to care for women who seek their help. Safe abortion services are cost effective, essential services for women. Men are part and parcel of the reason women resort to terminating a pregnancy, and, together with the countless children whose lives are dependent on a healthy caring mother, are also beneficiaries of safe abortion services. There can be no excuse for continuing to deny these services to so many women around the world.

  13. Drug discovery using chemical systems biology: repositioning the safe medicine Comtan to treat multi-drug and extensively drug resistant tuberculosis.

    Directory of Open Access Journals (Sweden)

    Sarah L Kinnings


    Full Text Available The rise of multi-drug resistant (MDR and extensively drug resistant (XDR tuberculosis around the world, including in industrialized nations, poses a great threat to human health and defines a need to develop new, effective and inexpensive anti-tubercular agents. Previously we developed a chemical systems biology approach to identify off-targets of major pharmaceuticals on a proteome-wide scale. In this paper we further demonstrate the value of this approach through the discovery that existing commercially available drugs, prescribed for the treatment of Parkinson's disease, have the potential to treat MDR and XDR tuberculosis. These drugs, entacapone and tolcapone, are predicted to bind to the enzyme InhA and directly inhibit substrate binding. The prediction is validated by in vitro and InhA kinetic assays using tablets of Comtan, whose active component is entacapone. The minimal inhibition concentration (MIC(99 of entacapone for Mycobacterium tuberculosis (M.tuberculosis is approximately 260.0 microM, well below the toxicity concentration determined by an in vitro cytotoxicity model using a human neuroblastoma cell line. Moreover, kinetic assays indicate that Comtan inhibits InhA activity by 47.0% at an entacapone concentration of approximately 80 microM. Thus the active component in Comtan represents a promising lead compound for developing a new class of anti-tubercular therapeutics with excellent safety profiles. More generally, the protocol described in this paper can be included in a drug discovery pipeline in an effort to discover novel drug leads with desired safety profiles, and therefore accelerate the development of new drugs.

  15. Safe domain and elementary geometry

    CERN Document Server

    Richard, J M


    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.

    为辅助汽车驾驶员安全驾驶,开发了一种汽车主动避撞系统。该系统以"碰撞时间倒数"TTC-1作为评价指标,采用了基于危险系数ε进行分级报警与主动制动的安全距离模型,其关键参数按照驾驶员特性进行标定。基于自适应巡航系统(ACC)目标检测算法,设计了适用于避撞系统的毫米波雷达算法。基于捷达轿车,开发了用于避撞系统的软硬件平台,并在良好路面下分别进行了主动避撞试验和人为切换试验。实车试验表明:本系统的分级报警和主动制动功能,符合期望的TTC-1指标,提高了汽车的主动安全性,体现了驾驶员控制的优先性和协调性。%Safe-driving was assisted with key parameters calibrated according to the driver’s characteristics using a developed system of vehicle collision warning and collision avoidance (CW/CA). The system defines the inverse of time-to-collision (TTC-1) as the evaluation index with the grading warning and braking safe distance model adopted based on hazardous level ε. A millimeter waveradar obstacle detection method was designed with adaptive cruise control (ACC). The system configuration and control logic were designed based on a Jetta car with the collision avoidance test and the manual / automatic interaction test implemented on dry roads. The real car experiments show that the CW/CA system in accordance with desired TTC-1 index improves vehicle active safety, and embodies the driver’s priority and cooperation.

  19. Keeping you safe by making machine tools safe

    CERN Multimedia


    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: ...

  3. Building a safe care-providing robot. (United States)

    Fotoohi, Leila; Gräser, Axel


    A service robot especially a care-providing robot, works in the vicinity of a human body and is sometimes even in direct contact with it. Conventional safety methods and precautions in industrial robotics are not applicable to such robots. This paper presents a safety approach for designing the safe care-providing robot FRIEND. The approach is applied in each step of design iteratively to identify and assess the potential hazards during design. The steps are explained briefly in this work. The main contribution of this paper is verification of safety requirements using the Ramadge-Wonham (RW) framework. The greater complexity of the tasks the robot will perform, the more complex is the identification of safety requirements. Use of this framework led us to analyze the requirements and verify them formally, systematically and on a modular basis. In our approach human-robot interaction (HRI) is also modeled by a set of uncontrolled events that may happen any time during operation. Subsequently the safety requirements are modified to consider these interactions. As a result the safety module behaves like a controller, running in parallel with the system, which maintains the system safe and works according to the safety requirements by enabling the admissible sequences of events.

  10. Creating a Safe, High-Quality Healthcare System for All: Meeting the Needs of Limited English Proficient Populations; Comment on “Patient Safety and Healthcare Quality: The Case for Language Access”

    Directory of Open Access Journals (Sweden)

    Joseph R. Betancourt


    Full Text Available The article by Cheri Wilson, “Patient Safety and Healthcare Quality: The Case for Language Access”, highlights 
the challenges of providing Culturally and Linguistically Appropriate Services (CLAS to patients with 
Limited English Proficiency (LEP. As the US pursues high-value, high-performance healthcare, our ability 
to meet the needs of our most vulnerable will determine whether we succeed or fail in the long run. With the 
implementation of the Affordable Care Act (ACA, this is more important than ever before, as it is estimated 
that the newly insured are more likely to be minority and less likely to speak English than their currently 
insured counterparts. As such, we must create a safe, high-quality healthcare system for all, especially in this 
time of incredible healthcare transformation and unprecedented diversity. Improving Patient Safety Systems for 
Patients With Limited English Proficiency: A Guide for Hospitals provides a blueprint for achieving this goal, 
and Massachusetts General Hospital (MGH is taking action.

    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.

    Halani, Sameer H; Riley, Jonathan P; Pradilla, Gustavo; Ahmad, Faiz U


    Traumatic neurologic injury in contact sports is a rare but serious consequence for its players. These injuries are most commonly associated with high-impact collisions, for example in football, but are found in a wide variety of sports. In an attempt to minimize these injuries, sports are trying to increase safety by adding protection for participants. Most recently is the seemingly 'safe' sport of Bubble Soccer, which attempts to protect its players with inflatable plastic bubbles. We report a case of a 16-year-old male sustaining a cervical spine burst fracture with incomplete spinal cord injury while playing Bubble Soccer. To our knowledge, this is the first serious neurological injury reported in the sport.

  13. The Difference Safe Spaces Make

    Directory of Open Access Journals (Sweden)

    Kendric Coleman


    Full Text Available In the last decade, lesbian, gay, bisexual, and transgender (LGBT students have become very visible at Historically Black Colleges and Universities (HBCUs, but this visibility is not reflected in some colleges’ student programs and activities. Only a few notable HBCUs, such as Howard University and Spelman College, have made a concerted effort. Acknowledging that the LGBT community is significant and exists, and fostering such support, comes up against a steep wall of religious tradition and doctrines, and conservative administrations. It is imperative that HBCUs address LGBT issues and create and support a safe space for students to articulate their identity. Meanwhile, many LGBT students on these campuses find voice and understanding in Black scholars and writers such as Audre Lorde’s Zami: A New Spelling of My Name and Charles Michael Smith’s Fighting Words: Personal Essays by Black Gay Men.

    Full Text Available El estudio de los gabinetes presidenciales se ha focalizado predominantemente en las formaciones de coalición, distinguiendo a los ministros en función de su afiliación partidaria particularmente en los momentos de instauración y terminación del gabinete. Este artículo desplaza el foco de análisis hacia los gabinetes de partido único para indagar las modalidades de selección de ministros en situaciones donde el soporte legislativo de coalición pierde relevancia. Se propone un modelo de análisis que incluye la observación de afiliaciones extrapartidarias, capacidades técnicas individuales y vínculos personales con el presidente, y se lo aplica al estudio del caso argentino. Los resultados sugieren que presidentes bien posicionados tienden a aplicar estrategias de distribución de ministerios más cerradas, con grados de institucionalidad que dependen de la organización partidaria del presidente y su estilo de liderazgo.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. Safe motherhood: when to begin. (United States)

    Verma, M; Chhatwal, J; Mathew, E


    Two thousand five hundred college girls were assessed for their knowledge and attitudes regarding sex, pregnancy and child rearing with the help of a pretested questionnaire. The site of menstruation was known to only 35.3% of the girls. The knowledge about the time and site of conception was 25.3% and 58.2%, respectively. Only 16.3% of the respondents knew the normal route of delivery although the duration of normal pregnancy was known to majority (87.7%). The girls were aware of the ideal timing of abortion (67.5%) but the safe method and legality were poorly known facts. Only 5% of the girls believed in pre-marital sex. More than half (54.9%) of the girls knew about some form of contraceptive, Copper-T being the best known. Nearly one fifth of the girls were either undecided or wished family members to decide about antenatal check-ups. The need for better diet and injections during pregnancy was well known although few (15.2%) were aware of the injections being tetanus toxoid. Only about 10% wanted a home delivery but one fourth felt that a Dai or a relative was suitable for conducting the delivery. An overwhelming majority of the students stated that knowledge about above facts was important and they would like to learn about them preferably during college education. It is recommended that 'Family life education' be provided during pre-adolescent and adolescent years to ensure a safe motherhood and a healthy child.

  18. Inside Maine's Medicine Cabinet: Findings From the Drug Enforcement Administration's Medication Take-Back Events. (United States)

    Stewart, Heather; Malinowski, Alexandra; Ochs, Leslie; Jaramillo, Jeanie; McCall, Kenneth; Sullivan, Meghan


    Objectives. We evaluated the quantity and type of medications obtained in unused-medications return programs and the proportion of medication waste. Methods. We analyzed data collected in 11 Maine cities in 2011 to 2013 during 6 Drug Enforcement Administration (DEA) national medication take-back events. Pharmacy doctoral student volunteers collected data under the supervision of law enforcement, independent of the DEA. Data entry into the Pharmaceutical Collection Monitoring System, through its interface with Micromedex, allowed for analysis of medication classification, controlled substance category, therapeutic class, and percentage of medication waste (units returned/units dispensed). Results. Medication take-back events resulted in return of 13 599 individual medications from 1049 participants. We cataloged 553 019 units (capsules, tablets, milliliters, patches, or grams), representing 69.7% medication waste. Noncontrolled prescription medications accounted for 56.4% of returns, followed by over-the-counter medications (31.4%) and controlled prescription medications (9.1%). Conclusions. The significant quantities of medications, including controlled substances, returned and high degree of medication waste emphasize the need for medication collection programs to further public health research and improve health in our communities.

  2. What is a safe lift? (United States)

    Espinoza, Kathy


    In a perfect world, a "safe" lift would be 51 pounds if the object is within 7 inches from the front of the body, if it is at waist height, if it is directly in front of the person, if there is a handle on the object, and if the load inside the box/bucket doesn't shift once lifted. If the load to be lifted does not meet all of these criteria, then it is an unsafe lift, and modifications must be made. Modifications would include lightening the load, getting help, or using a mechanical lifting device. There is always a way to turn an unsafe lift into a safer lift. An excellent resource for anyone interested in eliminating some of the hazards associated with lifting is the "Easy Ergonomics" publication from Cal/OSHA. This booklet offers practical advice on how to improve the workplace using engineering and administrative controls, problem-solving strategies and solutions, and a vast amount of ergonomics information and resources. "Easy Ergonomics" can be obtained by calling Cal/OSHA's education and training unit in Sacramento at 800-963-9424. A free copy can be obtained via

  6. Dimensionally reduced gravity theories are asymptotically safe

    Energy Technology Data Exchange (ETDEWEB)

    Niedermaier, Max E-mail:


    4D Einstein gravity coupled to scalars and abelian gauge fields in its 2-Killing vector reduction is shown to be quasi-renormalizable to all loop orders at the expense of introducing infinitely many essential couplings. The latter can be combined into one or two functions of the 'area radius' associated with the two Killing vectors. The renormalization flow of these couplings is governed by beta functionals expressible in closed form in terms of the (one coupling) beta function of a symmetric space sigma-model. Generically the matter coupled systems are asymptotically safe, that is the flow possesses a non-trivial UV stable fixed point at which the trace anomaly vanishes. The main exception is a minimal coupling of 4D Einstein gravity to massless free scalars, in which case the scalars decouple from gravity at the fixed point.

  7. Safe Laser Beam Propagation for Interplanetary Links (United States)

    Wilson, Keith E.


    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.

    water temperatures of July, and higher cladoceran densities compared to June. River release Lower survival of the early Clark Fork is attributed to the exceptionally high river flows (1,984 cm /s or 70,000 ft /s) and low density of zooplankton. Age of adult kokanee sampled at Sullivan Springs was 1% age 2, 46% age 3, and 53% age 4. The high proportion of age 3 kokanee resulted in lower average fecundity. Recovery of about 160 fin clipped kokanee at Sullivan Springs provided evidence of imprinting. About 0.4% of the marked kokanee released in 1988 returned to spawn at age 3. This failure of a spawning run to Clark Fork River and low (<0.000l%) returns to the Cabinet Gorge Hatchery is a major concern. Total fishing effort was 460,679 h (220%) or about 12 h/hectare. A sport fishery survey indicated anglers harvested 276,457 fish of which 227,140 were kokanee and 2,157 Gerrard rainbow trout Oncorhynchus mykiss (>610 mm) while an additional 14,800 rainbow trout Oncorhynchus mykiss were released. The harvest of kokanee is at 33% of the management goals, but the harvest of large Gerrard rainbow trout was the best in 15 years.

    By using different recent state-of-the-art numerical techniques, such as the OFLI2 chaos indicator and a systematic search of symmetric periodic orbits, we get an insight into the dynamics of open Hamiltonians. We have found that this kind of system has safe bounded regular regions inside the escape region that have significant size and that can be located with precision. Therefore, it is possible to find regions of nonzero measure with stable periodic or quasi-periodic orbits far from the last KAM tori and far from the escape energy. This finding has been possible after a careful combination of a precise 'skeleton' of periodic orbits and a 2D plate of the OFLI2 chaos indicator to locate saddle-node bifurcations and the regular regions near them. Besides, these two techniques permit one to classify the different kinds of orbits that appear in Hamiltonian systems with escapes and provide information about the bifurcations of the families of periodic orbits, obtaining special cases of bifurcations for the different symmetries of the systems. Moreover, the skeleton of periodic orbits also gives the organizing set of the escape basin's geometry. As a paradigmatic example, we study in detail the Henon-Heiles Hamiltonian, and more briefly the Barbanis potential and a galactic Hamiltonian.

    The most difficult phase of small Unmanned Aerial System (sUAS) deployment is autonomous operations below the notional 50 ft in urban landscapes. Understanding the feasibility of safely flying sUAS autonomously below 50 ft is a game changer for many civilian applications. This paper outlines three areas of research currently underway which address key challenges for flight in the urban landscape. These are: (1) Off-line and On-board wind estimation and accommodation; (2) Real-time trajectory planning via characterization of obstacles using a LIDAR; (3) On-board information fusion for real-time decision-making and safe trajectory generation.

  4. Audiomagnetotelluric data to characterize the Revett-type copper-silver deposits at Rock Creek in the Cabinet Mountains Wilderness, Montana (United States)

    Sampson, Jay A.; Rodriguez, Brian D.


    The Revett-type deposits at Rock Creek are part of the concealed stratabound copper-silver deposits located in the Cabinet Mountains Wilderness of Montana. The U.S. Geological Survey is conducting a series of multidisciplinary studies as part of the Assessment Techniques for Concealed Mineral Resources project. Geologic, geochemical, geophysical, and mineral resources data are being evaluated with existing and new mineral deposit models to predict the possibility and probability of undiscovered deposits in covered terranes. To help characterize the size, resistivity, and depth of the mineral deposit concealed beneath thick overburden, a regional southwest-northeast audiomagnetotelluric sounding profile was acquired. Further studies will attempt to determine if induced polarization parameters can be extracted from the magnetotelluric data to determine the size of the mineralized area. The purpose of this report is to release the audiomagnetotelluric sounding data collected along that southwest-northeast profile. No interpretation of the data is included.

  6. How Safe Is Safe for Marine Toxins Monitoring?

    Directory of Open Access Journals (Sweden)

    Luis M. Botana


    Full Text Available Current regulation for marine toxins requires a monitoring method based on mass spectrometric analysis. This method is pre-targeted, hence after searching for pre-assigned masses, it identifies those compounds that were pre-defined with available calibrants. Therefore, the scope for detecting novel toxins which are not included in the monitoring protocol are very limited. In addition to this, there is a poor comprehension of the toxicity of some marine toxin groups. Also, the validity of the current approach is questioned by the lack of sufficient calibrants, and by the insufficient coverage by current legislation of the toxins reported to be present in shellfish. As an example, tetrodotoxin, palytoxin analogs, or cyclic imines are mentioned as indicators of gaps in the system that require a solid comprehension to assure consumers are protected.

  7. InaSAFE applications in disaster preparedness (United States)

    Pranantyo, Ignatius Ryan; Fadmastuti, Mahardika; Chandra, Fredy


    Disaster preparedness activities aim to reduce the impact of disasters by being better prepared to respond when a disaster occurs. In order to better anticipate requirements during a disaster, contingency planning activities can be undertaken prior to a disaster based on a realistic disaster scenario. InaSAFE is a tool that can inform this process. InaSAFE is a free and open source software that estimates the impact to people and infrastructure from potential hazard scenarios. By using InaSAFE, disaster managers can develop scenarios of disaster impacts (people and infrastructures affected) to inform their contingency plan and emergency response operation plan. While InaSAFE provides the software framework exposure data and hazard data are needed as inputs to run this software. Then InaSAFE can be used to forecast the impact of the hazard scenario to the exposure data. InaSAFE outputs include estimates of the number of people, buildings and roads are affected, list of minimum needs (rice and clean water), and response checklist. InaSAFE is developed by Indonesia's National Disaster Management Agency (BNPB) and the Australian Government, through the Australia-Indonesia Facility for Disaster Reduction (AIFDR), in partnership with the World Bank - Global Facility for Disaster Reduction and Recovery (GFDRR). This software has been used in many parts of Indonesia, including Padang, Maumere, Jakarta, and Slamet Mountain for emergency response and contingency planning.

  9. Distributed Programming via Safe Closure Passing

    Directory of Open Access Journals (Sweden)

    Philipp Haller


    Full Text Available Programming systems incorporating aspects of functional programming, e.g., higher-order functions, are becoming increasingly popular for large-scale distributed programming. New frameworks such as Apache Spark leverage functional techniques to provide high-level, declarative APIs for in-memory data analytics, often outperforming traditional "big data" frameworks like Hadoop MapReduce. However, widely-used programming models remain rather ad-hoc; aspects such as implementation trade-offs, static typing, and semantics are not yet well-understood. We present a new asynchronous programming model that has at its core several principles facilitating functional processing of distributed data. The emphasis of our model is on simplicity, performance, and expressiveness. The primary means of communication is by passing functions (closures to distributed, immutable data. To ensure safe and efficient distribution of closures, our model leverages both syntactic and type-based restrictions. We report on a prototype implementation in Scala. Finally, we present preliminary experimental results evaluating the performance impact of a static, type-based optimization of serialization.

  10. Topological characterization of safe coordinated vehicle motions

    Energy Technology Data Exchange (ETDEWEB)



    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.

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


    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.

Therefore, we examined automatic preferences towards safe and risky driving with a Go/No-go Association Task (GNAT). The results suggest that (1) implicit attitudes towards driving behavior can be measured reliably...... with the GNAT; (2) implicit attitudes towards safe driving versus towards risky driving may be separable constructs. We propose that research on driving behavior may benefit from routinely including measures of implicit cognition.

  6. Managing Cassini Safe Mode Attitude at Saturn (United States)

    Burk, Thomas A.


    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. Safe Human-Robot Cooperation in an Industrial Environment

    Directory of Open Access Journals (Sweden)

    Nicola Pedrocchi


    Full Text Available The standard EN ISO10218 is fostering the implementation of hybrid production systems, i.e., production systems characterized by a close relationship among human operators and robots in cooperative tasks. Human‐robot hybrid systems could have a big economic benefit in small and medium sized production, even if this new paradigm introduces mandatory, challenging safety aspects. Among various requirements for collaborative workspaces, safety‐assurance involves two different application layers; the algorithms enabling safe space‐sharing between humans and robots and the enabling technologies allowing acquisition data from sensor fusion and environmental data analysing. This paper addresses both the problems: a collision avoidance strategy allowing on‐line re‐planning of robot motion and a safe network of unsafe devices as a suggested infrastructure for functional safety achievement.

  13. Teaching safe sex practices to psychiatric patients. (United States)

    Sladyk, K


    An occupational therapist presented her 45-minute program called AIDS Education and Safe Sex 5 times to female mental patients in the locked ward of Cedarcrest Regional Hospital in Newington, Connecticut, to inform them about safe-sex practices and AIDS. She first administered a pretest then spoke briefly about AIDS and safe-sex practices. The lecture emphasized various important points such as no cure for AIDS exist, casual contact (e.g., kiss on the cheek, handshake) cannot transmit HIV, and effectiveness of using latex condoms. The occupational therapist spent much of her time addressing myths about AIDS and what safe-sex practices are. The patients discussed sexual abuse and dishonest partners. She administered a posttest which was the same as the pretest. Some sessions attracted more people than did other sessions. Test scores increased for every patient and for every session. They ranged from a 5% (68-73%) increase for the 3rd session to a 24% (67-91%) increase for the last session. She was not able to determine, however, whether the increased knowledge would translate into positive behavioral changes. Patients' psychiatric symptoms may have interfered with learning resulting in less than ideal improvements in knowledge. These symptoms were hypomanic behavior, restlessness, and distractibility. Perhaps other sessions with experiential techniques (e.g., putting condoms on dummies) would increase their understanding. This program helps fill the information gap not provided by the mass media which avoid mentioning safe-sex practices.

  14. Design of Weishaupt burner's safe use in heat medium heater system%威索燃烧器在热煤炉系统中的安全使用设计

    Institute of Scientific and Technical Information of China (English)



    为了解决热煤炉点炉受环境因素影响这一难题,中石油管道公司引入国外先进的点炉装置--威索燃烧器.为了安全有效的使用和控制威索燃烧器,在控制电路上,我们采用"远程控制"和"现场控制"相结合的方法,为该设备的安全使用上了一个"双保险".实践证明,采用这种电路来控制这套装置,在热煤炉正常运行过程中,可以在"远程控制"和"现场控制"之间自由切换,不需要停炉.而且在两种控制方式当中的一种失灵的情况下,仍然可以对热煤炉的运行进行安全的保护.因此,通过威索燃烧器的安全使用可以为原油的输送安全提供更好的保障.%To solve the hard problem that the ignition of heat medium heater is affected by environment, China Petroleum Pipeline Company introduced the advanced igniting equipment Weishaupt Oil Burner from abroad. In order to use and control the burner safely and effectively, "remote control" and "local control" were combined in the control circuit, which offers "a double insurance" for the equipment's safe use. Practice has proved that the conjoint control of this equipment can realize flee switches between the remote control and local control in the normal running of the heat medium heater instead of stopping the heater. The conjoint control can insure the safe protection of the heater when one control fails. The,use of the Weishaupt Oil Burner can guarantee the safe conveyance of crude oil.

  15. Sun Safe Mode Controller Design for LADEE (United States)

    Fusco, Jesse C.; Swei, Sean S. M.; Nakamura, Robert H.


    This paper presents the development of sun safe controllers which are designed to keep the spacecraft power positive and thermally balanced in the event an anomaly is detected. Employed by NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE), the controllers utilize the measured sun vector and the spacecraft body rates for feedback control. To improve the accuracy of sun vector estimation, the least square minimization approach is applied to process the sensor data, which is proven to be effective and accurate. To validate the controllers, the LADEE spacecraft model engaging the sun safe mode was first simulated and then compared with the actual LADEE orbital fight data. The results demonstrated the applicability of the proposed sun safe controllers.

  19. [The Biometric Cabinet of the Escola de Educação Física do Exército: measuring and classifying to produce ideal bodies, 1930-1940]. (United States)

    Gomes, Ana Carolina Vimieiro; Silva, André Luiz Dos Santos; Vaz, Alexandre Fernandez


    This paper analyzes biometrical and biotypological practices of the Biometric Cabinet of the Escola de Educação Física do Exército (Physical Education School of the Army) in Rio de Janeiro in the 1930s and 1940s, published in Revista de Educação Física do Exército. It was necessary to classify, monitor the results of the exercises periodically and measure morphological aspects of the bodies. The classifications were made in accordance with foreign parameters and an attempt was made to classify by type, quality and defects. The analysis of the practices of the Cabinet shows that biometrics and biotypology were complementary aspects of physical education, aiming at the standardization of bodies.

    Directory of Open Access Journals (Sweden)

    Pascale Mormiche


    Full Text Available Cette communication concerne l’enseignement scientifique des princes et la composition de cabinet d’instruments scientifiques. Le premier cabinet constitué à Versailles est celui des enfants de France établi sous le contrôle des Menus-Plaisirs. À partir de 1758, il se compose d’instruments choisis parmi les 345 décrits dans le catalogue de l’abbé Nollet en 1738 dans son « Programme ou Idée générale d’un cours de physique expérimentale… ». 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 ? On peut comparer utilement avec un cabinet dont on connaît le rare inventaire d’achat, celui de Mme du Châtelet et Voltaire possédant également des instruments Nollet. L’analyse de ces inventaires va bien au-delà du simple choix d’instruments pour constituer le cabinet de physique des Enfants de France. Il s’agit de relier les instruments avec la pratique pédagogique des princes en montrant la création d’une « discipline scolaire » enseignée aux princes, alors que se déroulent des d

    Full Text Available El artículo examina la elección de los ministros y estima las posibilidades de selección de los políticos profesionales vis-à-vis la selección de técnicos o políticos novatos en gabinetes multipartidistas. La selección ministerial es analizada como un cálculo partidario para convertir la designación ministerial en un recurso para la retención y/o proyección de sus cuadros partidarios. Se testearon dos hipótesis: a la lealtad, los vínculos partidarios y la pertenencia a partidos competitivos aumentan las chances de selección de políticos profesionales para el cargo de ministro; b las probabilidades de selección de políticos novatos o tecnócratas aumentan con la expertise o la pertenencia a partidos en fase de expansión organizacional. El análisis se concentra en los gobiernos multipartidistas formados en Brasil (1995-2010. Los resultados muestran que la trayectoria dentro del partido es decisiva para la selección de políticos profesionales, mientras que la pertenencia al partido del presidente favorece el ingreso de nuevos cuadros en el gobierno. El estudio presenta evidencias sobre la complejidad de la selección ministerial en gabinetes multipartidistas a la luz de los dilemas organizacionales enfrentados por los partidos.The article examines the ministerial selection and estimates the chances of selection of professional politicians vis-à-vis the selection of technocrats or political novice in multiparty cabinets.

  3. Landscape planning for a safe city

    Directory of Open Access Journals (Sweden)

    M. Ishikawa


    Full Text Available To create a safe city free from natural disasters has been one of the important criteria in city planning. Since large cities have suffered from large fires caused by earthquakes, the planning of open spaces to prevent the spread of fires is part of the basic structure of city planning in Japan. Even in the feudal city of Edo, the former name of Tokyo, there had been open spaces to prevent fire disasters along canals and rivers. This paper discusses the historical evolution of open space planning, that we call landscape planning, through the experiences in Tokyo, and clarifies the characteristics and problems for achieving a safe city.

    Aiming at the shortcoming existing in the traditional automatic switching operation between the incoming cabinet and the bus tie breaker cabinet at 6 kV high-voltage substation, this paper proposed to adopt programmable logic controller control (PLC) technology to re-alize new ways of automatically switching, building up the simulation model of substation, expounding manners and contents of the switch-ing operation, enumerating the I/O allocation table controlled by PLC and giving the external wiring diagram and the control ladder diagram. Experimental tests show that the method not only makes all kinds of operation function more perfect, but also makes the operation procedure correct and unique, and it can immediately send light and sound alarm signals for any wrong operation, without causing substantive misop-eration results.%针对6 kV高压变电站进线柜与母联柜传统自动切换操作中存在的不足,提出采用可编程控制器(PLC)控制技术实现自动切换的新方法。建立了变电站的仿真模型,阐述了倒闸操作的方式与内容,列举了PLC控制的I/O分配表,给出了外部接线图以及控制梯形图等。经实验测试,该方法不仅使各种操作功能更加完备,而且操作途径正确、唯一,对错误的操作能立即发出声光报警信号,而不会引起实质性的误操作结果。

  2. Performance study of a heat pump dryer system for speciality crops - Pt. 2: model verification

    Adapa, P.K.; Schoenau, G.J.; Sokhansanj, S. [University of Saskatchewan (Canada). College of Engineering


    The experimental and predicted performance data of a heat pump dryer system is reported. Chopped alfalfa was dried in a cabinet dryer in batches and also by emulating continuous bed drying using two heat pumps operating in parallel. Results showed that alfalfa was dried from an initial moisture content of 70% (wb) to a final moisture content of 10% (wb). The batch drying took about 4.5 h while continuous bed drying took 4 h to dry the same amount of material. The average air velocity inside the dryer was 0.36 m s{sup -1}. Low temperatures (30-45{sup o}C) for safe drying of specialty crops were achieved experimentally. The heat pump drying system used in this study was about 50% more efficient in recovering the latent heat from the dryer exhaust compared to the conventional dryers. Specific moisture extraction rate (SMER) was maximum when relative humidity stayed above 40%. The dryer was shown to be capable of SMER of between 0.5 and 1.02 kg kW{sup -1} h{sup -1}. It was concluded that continuous bed drying is potentially a better option than batch drying because high process air humidity ratios at the entrance of the evaporator and constant moisture extraction rate and specific moisture extraction rate values can be maintained. An uncertainty analysis confirmed the accuracy of the model. (author)

    Dong, Shuonan; Conrad, Patrick R.; Shah, Julie A.; Williams, Brian C.; Mittman, David S.; Ingham, Michel D.; Verma, Vandana


    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.

    Full Text Available Hamde Nazar,1 Mahdi Nazar,2 Charlotte Rothwell,1 Jane Portlock,3 Andrew Chaytor,1 Andrew Husband1 1School of Medicine, Pharmacy and Health, Durham University, UK; 2Cumberland Infirmary, North Cumbria University Hospitals NHS Trust, UK; 3School of Pharmacy and Biomedical Sciences, University of Portsmouth, UK Abstract: Prescribing is a characteristic role of a medical practitioner. On graduating from medical school, students are presumed to have acquired the necessary pharmacology knowledge underpinning the therapeutics and developed their personal skills and behaviors in order to write a safe and effective prescription (The Four Ps. However, there are reports of errors in medical prescribing and dissatisfied feedback from recent graduates, which evidence potential flaws in the current training in the practice of prescribing. We examine the Four Ps from a systems approach and offer scope for educators and curriculum designers to review and reflect on their current undergraduate teaching, learning, and assessment strategies in a similar manner. We also adopt a national framework of common competencies required of all prescribers to remain effective and safe in their area of practice as a more objective layer to the broader learning outcomes of the General Medical Council Tomorrow's Doctors 2009. This exercise demonstrates where standard, recognized competencies for safe prescribing can be accommodated pedagogically within existing medical curricula.Keywords: prescribing, medical curriculum, clinical pharmacology teaching, therapeutics, education

  10. Safe Public Debt: Towards an Operational Definition

    Directory of Open Access Journals (Sweden)

    Xavier Debrun


    Full Text Available The paper proposes an operational definition of safe public debt levels and discusses various concrete approaches to calculate them. A public debt level is considered safe if it is associated with a low probability of reaching levels likely to generate significant economic costs within a given time frame. Like debt sustainability assessments, implementing such a broad definition requires medium-term projections of the debt-to-GDP ratio. This implies that different sets of plausible assumptions can yield fairly different “safe” debt levels for the same country. However, the proposed framework has the merit to force policymakers and analysts to be explicit about the assumptions underlying their calculations.

  11. Perioperative Care of Prisoners: Providing Safe Care. (United States)

    Smith, Francis Duval


    Correctional nurses are trained to care for prisoners in a controlled security environment; however, when a convict is transferred to a noncorrectional health care facility, the nurses there are often unfamiliar with custody requirements or how to safely care for these patients. The care of prisoners outside of prison has not been adequately investigated, and a gap exists between research and nursing education and practice. Nurses rarely have to consider how providing care for a prisoner in custody affects their practice, the potential dissonance between routine nursing care and the requirements to maintain security, or that care of prisoners in unsecured clinical areas places the nurse and other personnel at risk for physical assault or prisoner escape. Educating perioperative nurses in the care of prisoners in a public hospital environment is important for the provision of safe care and prevention of physical and emotional repercussions to personnel.

  14. Inherently safe in situ uranium recovery.

    Energy Technology Data Exchange (ETDEWEB)

    Krumhansl, James Lee; Beauheim, Richard Louis; Brady, Patrick Vane; Arnold, Bill Walter; Kanney, Joseph F.; McKenna, Sean Andrew


    Expansion of uranium mining in the United States is a concern to some environmental groups and sovereign Native American Nations. An approach which may alleviate some problems is to develop inherently safe in situ uranium recovery ('ISR') technologies. Current ISR technology relies on chemical extraction of trace levels of uranium from aquifers that, once mined, can still contain dissolved uranium and other trace metals that are a health concern. Existing ISR operations are few in number; however, high uranium prices are driving the industry to consider expanding operations nation-wide. Environmental concerns and enforcement of the new 30 ppb uranium drinking water standard may make opening new mining operations more difficult and costly. Here we propose a technological fix: the development of inherently safe in situ recovery (ISISR) methods. The four central features of an ISISR approach are: (1) New 'green' leachants that break down predictably in the subsurface, leaving uranium, and associated trace metals, in an immobile form; (2) Post-leachant uranium/metals-immobilizing washes that provide a backup decontamination process; (3) An optimized well-field design that increases uranium recovery efficiency and minimizes excursions of contaminated water; and (4) A combined hydrologic/geochemical protocol for designing low-cost post-extraction long-term monitoring. ISISR would bring larger amounts of uranium to the surface, leave fewer toxic metals in the aquifer, and cost less to monitor safely - thus providing a 'win-win-win' solution to all stakeholders.

    Full Text Available La présente étude a pour ambition de vérifier s’il existe un lien empirique entre le comportement des audités et la qualité de l’audit au Cameroun. Nous avons à cet effet appréhendé la qualité de l’audit via les qualités de l’auditeur (sa compétence et son indépendance. En s’appuyant sur les analyses de classification et économétriques par la méthode de régression logistique sur des données recueillies par questionnaire auprès de 40 cabinets d’audits présents au Cameroun, les résultats montrent d’une part que la qualité de l’audit est plutôt altérée dans notre contexte. D’autre part, cette étude relève que la probabilité d’avoir un audit de qualité est d’autant plus grande lorsque les honoraires sont négociés à la hausse permanemment et, d’autant plus faible, si l’audité est absent lors du déroulement de la mission, ou s’il accuse des retards dans le paiement des honoraires ou encore, lorsqu’il n’a pas fourni à temps tous les documents nécessaires pour mener à bien la mission.

  18. Fault Diagnosis of Power Systems Using Intelligent Systems (United States)

    Momoh, James A.; Oliver, Walter E. , Jr.


    The power system operator's need for a reliable power delivery system calls for a real-time or near-real-time Al-based fault diagnosis tool. Such a tool will allow NASA ground controllers to re-establish a normal or near-normal degraded operating state of the EPS (a DC power system) for Space Station Alpha by isolating the faulted branches and loads of the system. And after isolation, re-energizing those branches and loads that have been found not to have any faults in them. A proposed solution involves using the Fault Diagnosis Intelligent System (FDIS) to perform near-real time fault diagnosis of Alpha's EPS by downloading power transient telemetry at fault-time from onboard data loggers. The FDIS uses an ANN clustering algorithm augmented with a wavelet transform feature extractor. This combination enables this system to perform pattern recognition of the power transient signatures to diagnose the fault type and its location down to the orbital replaceable unit. FDIS has been tested using a simulation of the LeRC Testbed Space Station Freedom configuration including the topology from the DDCU's to the electrical loads attached to the TPDU's. FDIS will work in conjunction with the Power Management Load Scheduler to determine what the state of the system was at the time of the fault condition. This information is used to activate the appropriate diagnostic section, and to refine if necessary the solution obtained. In the latter case, if the FDIS reports back that it is equally likely that the faulty device as 'start tracker #1' and 'time generation unit,' then based on a priori knowledge of the system's state, the refined solution would be 'star tracker #1' located in cabinet ITAS2. It is concluded from the present studies that artificial intelligence diagnostic abilities are improved with the addition of the wavelet transform, and that when such a system such as FDIS is coupled to the Power Management Load Scheduler, a faulty device can be located and isolated

  19. Promoting safe motherhood in rural India. (United States)

    Maclean, G


    This article identifies some activities performed to promote safe motherhood in rural India. Nurses from a voluntary organization in Hyderabad, India, trained women's groups from 32 villages in rural Andhra Pradesh state over 3 days in 1996 in maternal and child care, health and family welfare, gender issues, sanitation, leadership, literacy, negotiating skills, and health monitoring. The women were encouraged to perform health activities in their villages. In October 1996, a Conference of Women celebrated the birthday of Mahatma Gandhi, with women's groups reporting on health activities in specific villages. Each women's group had its own banner. Every woman wore a conference delegate badge. One woman's group was rewarded for making the most significant progress. Participants included women from 29 villages and auxiliary nurse-midwives. For some women, this was the first time away from home. Conference delegates toured the primary health center facilities at Shamirpet and met with staff. The aim was to reduce fear and reluctance to use the services and to promote awareness of available health care. Most villages in India rely on auxiliary nurse-midwives for maternal and child health care. Promotion of safe motherhood requires close cooperation between the auxiliary nurse-midwifes and women's groups. The Ministry of Health and Family Welfare of India is introducing in-service training to improve the clinical skills of auxiliary nurse-midwives in eight states. The nurse-midwives use adapted and new educational material from WHO's safe motherhood midwifery training modules. A workshop was used to introduce the new modules and to propose teaching methods for senior project staff. The five modules include a trainers' manual of educational methods.

    Joel Z Stengel; Hays L Arnold


    Inflammatory bowel disease (IBD) often affects women around the age of conception and pregnancy. Most drugs used to treat IBD are safe in pregnancy, but physicians must consider the clinical implications of certain treatment regimens in young, fertile females. We report an informative case of a pregnant patient with IBD who underwent treatment with infliximab during her pregnancy and while nursing her infant. Serum and breast milk infliximab levels were monitored throughout this time period. This case report suggests that targeted monoclonal antibodies and other biologic agents can be used with caution in pregnant and breastfeeding patients.

    Full Text Available Background. Organizing and performing patient transfers in the continuum of care is part of the work of nurses and other staff of a multiprofessional healthcare team. An understanding of discharge practices is needed in order to ultimate patients’ transfers from high technological intensive care units (ICU to general wards. Aim. To describe, as experienced by intensive care and general ward staff, what strategies could be used when organizing patient’s care before, during, and after transfer from intensive care. Method. Interviews of 15 participants were conducted, audio-taped, transcribed verbatim, and analyzed using qualitative content analysis. Results. The results showed that the categories secure, encourage, and collaborate are strategies used in the three phases of the ICU transitional care process. The main category; a safe, interactive rehabilitation process, illustrated how all strategies were characterized by an intention to create and maintain safety during the process. A three-way interaction was described: between staff and patient/families, between team members and involved units, and between patient/family and environment. Discussion/Conclusions. The findings highlight that ICU transitional care implies critical care rehabilitation. Discharge procedures need to be safe and structured and involve collaboration, encouraging support, optimal timing, early mobilization, and a multidiscipline approach.

  6. Safety analysis and realization of safe information transmission optical LAN on high-speed railway (United States)

    Tao, Ying; Wu, Chongqing; Li, Zuoyi


    High-speed railway that has been progressing very quickly is one of the greatest techniques in present time because of its high speed, economy, comfort, environment benefits and other advantages. And among all of these, safe is the backbone and lifeline, so the chief task in developing high-speed railway is to establish safety guarantee system. Also in this safety guarantee system, train control is one of the key techniques to guarantee safe train operation and to advance ability of transportation, so operation safe is located in the hardcore position. That is to say, it is imperative to set up a safe, real-time and reliable automatic train control system. And we can easily find out that this kind of system is now developed and applied in many countries. Important information related to train control, such as the received and transmitted information of track-sided equipment, is called safe information, because it deals with train operation's safe, reliability, and even directly with people's life and wealth. It is so important that if there were some kind of fault with its making, transmission, or processing, fatal accident would occur. So to some degree, it is impossible to transmit and process this information through present railway communication network because of the former's extreme importance and the latter's no safe capability. Therefore, a specific communication network that mainly considers about safe transmission and management should be established in order to realize the specific function for this specific information. High-speed railway safe information transmission optical LAN, which adopts optical fiber as transmission media and transmits safe information, is a kind of LAN designed for the request for safe, real-time and highly reliable automatic train control system in the process of our country's high-speed railway construction and commonly train speed. In this paper, after analyzing the characteristics of automatic train control system and the

    Surgery is essential for global cancer care in all resource settings. Of the 15.2 million new cases of cancer in 2015, over 80% of cases will need surgery, some several times. By 2030, we estimate that annually 45 million surgical procedures will be needed worldwide. Yet, less than 25% of patients with cancer worldwide actually get safe, affordable, or timely surgery. This Commission on global cancer surgery, building on Global Surgery 2030, has examined the state of global cancer surgery through an analysis of the burden of surgical disease and breadth of cancer surgery, economics and financing, factors for strengthening surgical systems for cancer with multiple-country studies, the research agenda, and the political factors that frame policy making in this area. We found wide equity and economic gaps in global cancer surgery. Many patients throughout the world do not have access to cancer surgery, and the failure to train more cancer surgeons and strengthen systems could result in as much as US $6.2 trillion in lost cumulative gross domestic product by 2030. Many of the key adjunct treatment modalities for cancer surgery--e.g., pathology and imaging--are also inadequate. Our analysis identified substantial issues, but also highlights solutions and innovations. Issues of access, a paucity of investment in public surgical systems, low investment in research, and training and education gaps are remarkably widespread. Solutions include better regulated public systems, international partnerships, super-centralisation of surgical services, novel surgical clinical trials, and new approaches to improve quality and scale up cancer surgical systems through education and training. Our key messages are directed at many global stakeholders, but the central message is that to deliver safe, affordable, and timely cancer surgery to all, surgery must be at the heart of global and national cancer control planning.

  20. Bacteriocins: safe, natural antimicrobials for food preservation. (United States)

    Cleveland, J; Montville, T J; Nes, I F; Chikindas, M L


    Bacteriocins are antibacterial proteins produced by bacteria that kill or inhibit the growth of other bacteria. Many lactic acid bacteria (LAB) produce a high diversity of different bacteriocins. Though these bacteriocins are produced by LAB found in numerous fermented and non-fermented foods, nisin is currently the only bacteriocin widely used as a food preservative. Many bacteriocins have been characterized biochemically and genetically, and though there is a basic understanding of their structure-function, biosynthesis, and mode of action, many aspects of these compounds are still unknown. This article gives an overview of bacteriocin applications, and differentiates bacteriocins from antibiotics. A comparison of the synthesis. mode of action, resistance and safety of the two types of molecules is covered. Toxicity data exist for only a few bacteriocins, but research and their long-time intentional use strongly suggest that bacteriocins can be safely used.

  1. Inherently safe in situ uranium recovery (United States)

    Krumhansl, James L; Brady, Patrick V


    An in situ recovery of uranium operation involves circulating reactive fluids through an underground uranium deposit. These fluids contain chemicals that dissolve the uranium ore. Uranium is recovered from the fluids after they are pumped back to the surface. Chemicals used to accomplish this include complexing agents that are organic, readily degradable, and/or have a predictable lifetime in an aquifer. Efficiency is increased through development of organic agents targeted to complexing tetravalent uranium rather than hexavalent uranium. The operation provides for in situ immobilization of some oxy-anion pollutants under oxidizing conditions as well as reducing conditions. The operation also artificially reestablishes reducing conditions on the aquifer after uranium recovery is completed. With the ability to have the impacted aquifer reliably remediated, the uranium recovery operation can be considered inherently safe.

  2. Polypropylene suture--is it safe? (United States)

    Calhoun, T R; Kitten, C M


    Polypropylene suture has steadily gained popularity for use in vascular and cardiac surgical procedures because of its long-term tensile strength and minimal tissue trauma. However, recently some questions have arisen concerning its safety. We recently had two cases of polypropylene fracture, one occurring early and the other late after operation. Comparison and collation of these two cases with other reports leads to the conclusion that polypropylene suture is safe in most situations, but care must be taken to avoid instrumentation trauma and kinking stresses at knots, which probably explain most of the reported cases of polypropylene failure. In addition, polypropylene probably should not be used in graft-to-graft anastomoses in which the continual sawing stresses of two rigid structures appears to lead to an excessive incidence of late suture fracture with resultant false aneurysm formation.

  4. Safe and Secure Services Based on NGN (United States)

    Fukazawa, Tomoo; Nisase, Takemi; Kawashima, Masahisa; Hariu, Takeo; Oshima, Yoshihito

    Next Generation Network (NGN), which has been undergoing standardization as it has developed, is expected to create new services that converge the fixed and mobile networks. This paper introduces the basic requirements for NGN in terms of security and explains the standardization activities, in particular, the requirements for the security function described in Y.2701 discussed in ITU-T SG-13. In addition to the basic NGN security function, requirements for NGN authentication are also described from three aspects: security, deployability, and service. As examples of authentication implementation, three profiles-namely, fixed, nomadic, and mobile-are defined in this paper. That is, the “fixed profile” is typically for fixed-line subscribers, the “nomadic profile” basically utilizes WiFi access points, and the “mobile profile” provides ideal NGN mobility for mobile subscribers. All three of these profiles satisfy the requirements from security aspects. The three profiles are compared from the viewpoint of requirements for deployability and service. After showing that none of the three profiles can fulfill all of the requirements, we propose that multiple profiles should be used by NGN providers. As service and application examples, two promising NGN applications are proposed. The first is a strong authentication mechanism that makes Web applications more safe and secure even against password theft. It is based on NGN ID federation function. The second provides an easy peer-to-peer broadband virtual private network service aimed at safe and secure communication for personal/SOHO (small office, home office) users, based on NGN SIP (session initiation protocol) session control.

  6. Development of Solar Biomass Drying System

    Directory of Open Access Journals (Sweden)

    Atnaw Samson Mekbib


    Full Text Available The purpose of this paper focuses on the experimental pre-treatment of biomass in agricultural site using solar energy as power source and contribution of common use and efficiency solar dryer system for consumer. The main purpose of this design for solar cabinet dryer is to dry biomass via direct and indirect heating. Direct heating is the simplest method to dry biomass by exposing the biomass under direct sunlight. The solar cabinet dryer traps solar heat to increase the temperature of the drying chamber. The biomass absorbs the heat and transforms the moisture content within the biomass into water vapour and then leaves the chamber via the exhaust air outlet. This problem however can be solved by adopting indirect solar drying system. High and controllable temperatures can be achieved as a fan is used to move the air through the solar collector. This project has successfully created a solar cabinet dryer that combines both direct and indirect solar drying systems and functions to dry biomass as well as crops effectively and efficiently with minimal maintenance. Hence, it is indeed a substitution for conventional dryers which are affordable to local farmers.

  7. Tracking progress towards safe motherhood: meeting the benchmark yet missing the goal? An appeal for better use of health-system output indicators with evidence from Zambia and Sri Lanka.

    Das, S; Singhal, S; Kumar, N; Rao, C M; Sumalatha, S; Dave, J; Dave, R; Nandakumar, K


    The standardised extract of root of safed musli (Chlorophytum borivilianum) was evaluated for its aphrodisiac potential and safety profile on reproductive system. Wistar albino rats were trained to provide sexual experience under a dim red light (10 W) in a glass tank. Male and female rats were placed periodically in the glass tank in a particular order, that is male followed by introduction of the receptive female. Dosing of extract was carried out for 54 days at 125 and 250 mg kg(-1) p.o to male rats. On 14th and 28th days, the animals were observed from the cage side for sexual behaviours. Safed musli at both dose levels enhanced sexual vigour and libido which might be useful for treatment of sexual dysfunction in male till 28th day. Safety profile was assessed after 54 days of drug treatment, where both doses showed an increase in sperm count and increase in sperm motility. Thus, it can be stated that both doses possessed the spermatogenic potential, which would be highly beneficial in treating oligospermia or low sperm count. After 54 days of study, there was increase in sperm abnormality (%) at both doses, but not more than 10%, which indicated that this formulation will not induce infertility.

  13. "Same Room, Safe Place": The Need for Professional Safe Sleep Unity Grows at the Expense of Families. (United States)

    Keene Woods, Nikki


    There are many different professional stances on safe sleep and then there is the reality of caring for a newborn. There is a debate among professionals regarding safe sleep recommendations. The continum of recommendations vary from the American Academy of Pediatrics (AAP) Safe Sleep Guidelines to the bed-sharing recommendations from the Mother-Baby Behavioral Sleep Laboratory. The lack of consistent and uniform safe sleep recommendations from health professionals has been confusing for families but has more recently raised a real professional ethical dilemma. Despite years of focused safe sleep community education and interventions, sleep-related infant deaths are on the rise in many communities. This commentary calls for a united safe sleep message from all health professionals to improve health for mothers and infants most at-risk, "Same Room, Safe Place."

  14. Bike to work safely (follow-up)

    CERN Multimedia

    Simon Baird, HSE Unit Head


    Following a recent article about safe cycling (see here), the Bulletin received a request for more details on the type of accidents that are reported.   An analysis of the 38 accidents involving bicycles reported this year up to the end of August reveals that the most common single cause of accidents is slippery surfaces: ice, snow, water and gravel, so the message here is to take extra care, particularly when cycling in bad weather. The second item on the list is obstacles of various kinds: collisions with kerbs, potholes and even the transition from roads to cycle paths. The lesson here is to pay close attention to the surface you’re cycling over, and if you do spot a pothole, even if it does not lead to an accident, report it so that it can be repaired. It’s also worth remembering that you’re more likely to avoid coming off your bike if you keep your hands on the handlebars. The third highest cause is collisions with other vehicles, and here there are lessons for ...

    CERN Document Server

    Macdonald, Lee


    How to Observe the Sun Safely, Second Edition gives all the basic information and advice the amateur astronomer needs to get started in observing our own ever-fascinating star. Unlike many other astronomical objects, you do not need a large telescope or expensive equipment to observe the Sun. And it is possible to take excellent pictures of the Sun with today's low-cost digital cameras! This book surveys what is visible on the Sun and then describes how to record solar features and measure solar activity levels. There is also an account of how to use H-alpha and Calcium-K filters to observe and record prominences and other features of the solar chromosphere, the Sun's inner atmosphere. Because we are just entering a period of high activity on the Sun, following a long, quiet period, this is a great time to get involved with solar observing. Still emphasizing safety first, this Second Edition reflects recent and exciting advances in solar observing equipment. Chapters 6 through 8 have been completely revised ...

  16. [Is undirected liver biopsy a safe procedure?]. (United States)

    Oliva, L; Hirt, M


    In the authors' group of 976 umaimed liver biopsies (ULB) 10 complications were recorded. The authors described them and compared them with reports from the world literature. Two patients from the group died after ULB. One as a result of biopsy from haemoperitoneum, the other patient died with delirium tremens after surgery called for by persisting peritoneal syndrome. In eight patients mild complications were involved. In five patients complications receded spontaneously, in three after administration of an analgetic. From the submitted paper ensues that ULB is not quite safe, even when used by an experienced physician and when all contraindications are respected. A smooth course is not ensured by a risk-free diagnosis, previous uncomplicated biopsies normal prebioptic haemocoagulation tests. It is essential to realize this with regard to every patient where we indicate ULB. It is better to omit it unless we are unequivocally convinced of its asset. The question thus is: What will be the benefit of ULB for the patient?

    Full Text Available Objective: To evaluate the safety and risk of cryopreservation in female fertility preservation. Data sources: The data analyzed in this review were the English articles from 1980 to 2013 from journal databases, primarily PubMed and Google scholar. The criteria used in the literature search show as following: (1 human; embryo; cryopreservation/freezing/vitrification, (2 human; oocyte/immature oocyte; cryopreservation/ freezing/vitrification, (3 human; ovarian tissue transplantation; cryopreservation/freezing/vitrification, (4 human; aneuploidy/DNA damage/epigenetic; cryopreservation/freezing/vitrification, and (5 human; fertility preservation; maternal age. Study selection: The risk ratios based on survival rate, maturation rate, fertilization rate, cleavage rate, implantation rate, pregnancy rate, and clinical risk rate were acquired from relevant meta-analysis studies. These studies included randomized controlled trials or studies with one of the primary outcome measures covering cryopreservation of human mature oocytes, embryos, and ovarian tissues within the last 7 years (from 2006 to 2013, since the pregnancy rates of oocyte vitrification were significantly increased due to the improved techniques. The data involving immature oocyte cryopreservation obtained from individual studies was also reviewed by the authors. Results: Vitrifications of mature oocytes and embryos obtained better clinical outcomes and did not increase the risks of DNA damage, spindle configuration, embryonic aneuploidy, and genomic imprinting as compared with fresh and slow-freezing procedures, respectively. Conclusions: Both embryo and oocyte vitrifications are safe applications in female fertility preservation.

  18. Outpatient coronary angioplasty: feasible and safe. (United States)

    Slagboom, Ton; Kiemeneij, Ferdinand; Laarman, Gert Jan; van der Wieken, Ron


    This study tested the safety and feasibility of coronary angioplasty on an outpatient basis. The purpose of this approach includes cost-effectiveness and patient comfort. Six hundred forty-four patients were randomized to either transradial or transfemoral PTCA using 6 Fr equipment. Patients were triaged to outpatient management based on a predefined set of predictors of an adverse outcome in the first 24 hr after initially successful coronary angioplasty. Three hundred seventy-five patients (58%) were discharged 4-6 hr after PTCA; 42% stayed in hospital overnight. In the outpatient group, one adverse event occurred (subacute stent thrombosis 7 hr postdischarge, nonfatal myocardial infarction). There were no major vascular complications. In the hospital group, 19 patients (7%) sustained an adverse cardiac even in the first 24 hr; 1 patient died. Patients treated via the femoral route had more (minor) bleeding complications (19 patients; 6%); in 17 of these, this was the sole reason that discharge was delayed. PTCA on an outpatient basis, performed via the radial or the femoral artery with low-profile equipment, is safe and feasible in a considerable part of a routine PTCA population. A larger proportion of transradial patients can be discharged due to a reduction in (minor) bleeding complications.

  20. Secrets of safe laparoscopic surgery: Anaesthetic and surgical considerations

    Directory of Open Access Journals (Sweden)

    Srivastava Arati


    Full Text Available In recent years, laparoscopic surgery has gained popularity in clinical practice. The key element in laparoscopic surgery is creation of pneumoperitoneum and carbon dioxide is commonly used for insufflation. This pneumoperitoneum perils the normal cardiopulmonary system to a considerable extent. Every laparoscopic surgeon should understand the consequences of pneumoperitoneum; so that its untoward effects can be averted. Pneumoperitoneum increases pressure on diaphragm, leading to its cephalic displacement and thereby decreasing venous return, which can be aggravated by the position of patient during surgery. There is no absolute contraindication of laparoscopic surgery, though we can anticipate some problems in conditions like obesity, pregnancy and previous abdominal surgery. This review discusses some aspects of the pathophysiology of carbon dioxide induced pneumoperitoneum, its consequences as well as strategies to counteract them. Also, we propose certain guidelines for safe laparoscopic surgery.

  1. Defining the safe current limit for opening ID photon shutter

    Energy Technology Data Exchange (ETDEWEB)

    Seletskiy, S. [Brookhaven National Lab. (BNL), Upton, NY (United States). Photon Sciences Dept.


    The NSLS-II storage ring is protected from possible damage from insertion devices (IDs) synchrotron radiation by a dedicated active interlock system (AIS). It monitors electron beam position and angle and triggers beam drop if beam orbit exceeds the boundaries of pre-calculated active interlock envelope (AIE). The beamlines (BL) and beamline frontends (FE) are designed under assumption that the electron beam is interlocked within the AIE. For historic reasons the AIS engages the ID active interlock (AI-ID) at any non-zero beam current whenever the ID photon shutter (IDPS) is getting opened. Such arrangement creates major inconveniences for BLs commissioning. Apparently there is some IDPS safe current limit (SCL) under which the IDPS can be opened without interlocking the e-beam. The goal of this paper is to find such limit.

    Farquar, G; Leif, R


    Biocompatible polymers with hydrolyzable chemical bonds have been used to produce safe, non-toxic fluorescent microspheres for material penetration studies. The selection of polymeric materials depends on both biocompatibility and processability, with tailored fluorescent properties depending on specific applications. Microspheres are composed of USFDA-approved biodegradable polymers and non-toxic fluorophores and are therefore suitable for tests where human exposure is possible. Micropheres were produced which contain unique fluorophores to enable discrimination from background aerosol particles. Characteristics that affect dispersion and adhesion can be modified depending on use. Several different microsphere preparation methods are possible, including the use of a vibrating orifice aerosol generator (VOAG), a Sono-Tek atomizer, an emulsion technique, and inkjet printhead. Applications for the fluorescent microspheres include challenges for biodefense system testing, calibrants for biofluorescence sensors, and particles for air dispersion model validation studies.

  6. B-Safe : a positive approach to safety

    Energy Technology Data Exchange (ETDEWEB)

    Watts, D.; Coulter, M. [British Columbia Hydro, Vancouver, BC (Canada)


    BC Hydro has implemented a behavioural safety program called B-Safe. The program provides a proactive, accurate method of measuring actual safety performances as an alternative to the traditional re-active method of using the number of past accidents as a measure of safety performance. The approach used in B-Safe is to motivate a work team to raise its level of safety performance through the use of positive reinforcement. Implementing B-Safe is accomplished with a coordinator trained in the overall concept of the B-Safe philosophy. Each safe behaviour is given a value in points to the members of a working team. B-Safe is voluntary and has the advantage that participants perform their own measurements and set their own goals. It is claimed to be easy to implement, requires only a few minutes of attention each week, helps to reduce accidents and enhances existing safety programs.

    Weinberg, A M; Spiewak, I


    The Swedish PIUS reactor and the German-American small modular high-temperature gas-cooled reactor are inherently safe-that is, their safety relies not upon intervention of humans or of electromechanical devices but on immutable principles of physics and chemistry. A second nuclear era may require commercialization and deployment of such inherently safe reactors, even though existing light-water reactors appear to be as safe as other well-accepted sources of central electricity, particularly hydroelectric dams.

  12. Fire-safe polymers and polymer composites (United States)

    Zhang, Huiqing

    The intrinsic relationships between polymer structure, composition and fire behavior have been explored to develop new fire-safe polymeric materials. Different experimental techniques, especially three milligram-scale methods---pyrolysis-combustion flow calorimetry (PCFC), simultaneous thermal analysis (STA) and pyrolysis GC/MS---have been combined to fully characterize the thermal decomposition and flammability of polymers and polymer composites. Thermal stability, mass loss rate, char yield and properties of decomposition volatiles were found to be the most important parameters in determining polymer flammability. Most polymers decompose by either an unzipping or a random chain scission mechanism with an endothermic decomposition of 100--900 J/g. Aromatic or heteroaromatic rings, conjugated double or triple bonds and heteroatoms such as halogens, N, O, S, P and Si are the basic structural units for fire-resistant polymers. The flammability of polymers can also be successfully estimated by combining pyrolysis GC/MS results or chemical structures with TGA results. The thermal decomposition and flammability of two groups of inherently fire-resistant polymers---poly(hydroxyamide) (PHA) and its derivatives, and bisphenol C (BPC II) polyarylates---have been systematically studied. PHA and most of its derivatives have extremely low heat release rates and very high char yields upon combustion. PHA and its halogen derivatives can completely cyclize into quasi-polybenzoxazole (PBO) structures at low temperatures. However, the methoxy and phosphate derivatives show a very different behavior during decomposition and combustion. Molecular modeling shows that the formation of an enol intermediate is the rate-determining step in the thermal cyclization of PHA. BPC II-polyarylate is another extremely flame-resistant polymer. It can be used as an efficient flame-retardant agent in copolymers and blends. From PCFC results, the total heat of combustion of these copolymers or blends

    Full Text Available A review of the literature indicates that food scientistsand health authorities in several countries, especiallymember countries of the European Union, are still veryconcerned about the potential health hazards ofoxidized products and lipid polymers formed inrepeatedly-used deep frying oils. During the fryingprocess at temperatures of 170° – 200°C, steam formedfrom moisture in the food being fried help volatileproducts rise to the surface of the frying medium andinto the kitchen atmosphere, imparting a mixture offried-flavours and off-flavours. The non-volatilecompounds formed, however, gradually build up in theoil as it is being repeatedly-used for food fryingoperations. These non-volatiles, primarily “polarcompounds” (PC and to a lesser extent lipid polymers,get absorbed into fried foods and eventually end up inour body system. Available local data suggests thatdeep-frying oil samples obtained from food hawkers andthose produced under simulated deep-frying conditionsin the laboratory, are generally safe as they contain PCwithin safe limits and rarely exceed the upper limit(UL of 25%. This contrasts with the situation in someEuropean countries where a very high proportion offrying oil samples collected from fast-food restaurantswere reported to contain PC exceeding this UL.Appropriately, promotion of Hazard Analysis andCritical Control Points (HACCP certification andgazetting of food regulations to limit the PC content infrying oils have been introduced in these countries toprotect the health of consumers. Meanwhile, simplegadgets/test kits are available commercially to monitorthe quality of the frying oil. This would greatly assistkitchen supervisors at restaurants and franchised friedfood outlets to know when best to change a batch offrying oil before the ULs of frying oil quality arebreached.

    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)

  17. Safe access to safe water in low income countries: water fetching in current times. (United States)

    Sorenson, Susan B; Morssink, Christiaan; Campos, Paola Abril


    A substantial portion of the world's population does not have ready access to safe water. Moreover, obtaining water may involve great expense of time and energy for those who have no water sources in or near home. From an historical perspective, with the invention of piped water, fetching water has only recently become largely irrelevant in many locales. In addition, in most instances, wells and clean surface water were so close by that fetching was not considered a problem. However, population growth, weather fluctuations and social upheavals have made the daily chore of carrying water highly problematic and a public health problem of great magnitude for many, especially women, in the poor regions and classes of the world. In this paper, we consider gender differences in water carrying and summarize data about water access and carrying from 44 countries that participated in the Multiple Indicator Cluster Survey (MICS) program. Women and children are the most common water carriers, and they spend considerable time (many trips take more than an hour) supplying water to their households. Time is but one measure of the cost of fetching water; caloric expenditures, particularly during droughts, and other measures that affect health and quality of life must be considered. The full costs of fetching water must be considered when measuring progress toward two Millennium Development Goals--increasing access to safe drinking water and seeking an end to poverty.

  18. Intrinsically Safe Robot Arm: Adjustable Static Balancing and Low Power Actuation

    Vermeulen, M.; Wisse, M.


    We present a design for a manipulator that is intrinsically mechanically safe, i.e. it can not cause pain (let alone damage) to a human being even if the control system has a failure. Based on the pressure pain thresholds for human skin, we derive a pinching safety constraint that limits the actuato
