    A record of what is currently known about STS ancillary equipment is presented in this user-oriented design so that a potential user may evaluate whether he could use the described ancillary equipment or if he would need to design and fabricate a payload-unique item. References that the user can use to obtain additional details and requirements to aid in his evaluation and decision are included.

  3. EVA tools and equipment reference book

    NASA Technical Reports Server (NTRS)

    Fullerton, R. K.

    1993-01-01

    This document contains a mixture of tools and equipment used throughout the space shuttle-based extravehicular activity (EVA) program. Promising items which have reached the prototype stage of development are also included, but should not be considered certified ready for flight. Each item is described with a photo, a written discussion, technical specifications, dimensional drawings, and points of contact for additional information. Numbers on the upper left-hand corner of each photo may be used to order specific pictures from NASA and contractor photo libraries. Points of contact were classified as either operational or technical. An operational contact is an engineer from JSC Mission Operations Directorate who is familiar with the basic function and on-orbit use of the tool. A technical contact would be the best source of detailed technical specifications and is typically the NASA subsystem manager. The technical information table for each item uses the following terms to describe the availability or status of each hardware item: Standard - Flown on every mission as standard manifest; Flight specific - Potentially available for flight, not flown every mission (flight certification cannot be guaranteed and recertification may be required); Reference only - Item no longer in active inventory or not recommended for future use, some items may be too application-specific for general use; and Developmental - In the prototype stage only and not yet available for flight. The current availability and certification of any flight-specific tool should be verified with the technical point of contact. Those tools built and fit checked for Hubble Space Telescope maintenance are program dedicated and are not available to other customers. Other customers may have identical tools built from the existing, already certified designs as an optional service.

  2. Personal protective equipment and dermal exposure.

    PubMed

    Evans, P G; McAlinden, J J; Griffin, P

    2001-02-01

    Personal protective equipment (PPE) should only be used as a control measure when other measures are inappropriate or are inadequate by themselves. The person undertaking a risk assessment must exercise his or her judgment to take into account the protection afforded by the PPE. There is, therefore, considerable scope for differences in approach and it would seem sensible to eliminate these differences and ensure consistency, where possible, by reaching agreement on the attenuating effect of PPE. However, there is growing evidence that the levels of protection indicated by laboratory-based tests may not be achieved in real use situations. Studies of workplace protection suggest that the spread of contaminants inside protective clothing, including gloves, is commonplace and significant. Insufficient attention may have been paid to the effect of factors such as temperature differentials on the permeation of chemical agents through protective materials. To investigate this, a test cell was designed and built to measure the breakthrough times and subsequent permeation rate of solvents through glove materials where the temperature inside and outside the glove was representative of those that can occur in the workplace. Two chemical solvents were tested against two different glove materials at three different temperature conditions. The differences between the breakthrough times and permeation rates were measured and compared to manufacturer's test data. The practical implications are considered for risk of health and safety to the wearer. PMID:11217735

  3. How to use personal protective equipment.

    PubMed

    Pang, Vicky; Carter, Yvonne; Scott, Janice; Salazar, Glenn; Johnson, Velor

    This article offers a refresher on what personal protective equipment (PPE) is, how to choose the right PPE and how to wear and remove it safely. PPE aims to improve staff and patient safety, but self-contamination commonly occurs during its removal; failure to remove PPE carefully can lead to contamination of the user's skin, own clothes, uniform or scrubs, hair, face and hands. The importance of correct PPE use has been highlighted by the ebola crisis and NHS preparations to deal with patients who are infected. PMID:26012067

    Greathouse, Daniel G.; Nalesnik, Richard P.

    1992-01-01

    Protection of the environment and environmental remediation requires the cooperation, at all levels, of government and industry. Intelligent processing equipment, in addition to other artificial intelligence based tools, was used by the Environmental Protection Agency to provide personnel safety and improve the efficiency of those responsible for protection and remediation of the environment. These exploratory efforts demonstrate the feasibility and utility of expanding development and widespread use of these tools. A survey of current intelligent processing equipment applications in the Agency is presented and is followed by a brief discussion of possible uses in the future.

  2. NASA Developments in Personnel Protective Equipment

    NASA Technical Reports Server (NTRS)

    Graf, John

    2015-01-01

    NASA has some unique and challenging PPE needs: there are credible threats to air quality (fire, ammonia leak, hydrazine leak)that require a contingency breathing apparatus that operates for many hours - but there is not enough space or up-mass to provide supplied air tanks. We cannot use "Scott Air Tanks" commonly used by firefighters and other first responders. NASA has developed a respirator based emergency breathing device. It uses a "one size fits everybody in the astronaut corps" hooded mask with excellent chemical permeability and fire resistance properties, and a filtering respirator cartridge that protects the wearer from ammonia leaks, hydrazine leaks, or products of combustion. If you need a small, lightweight emergency breathing system that lasts longer than a supplied air system, we should meet and learn if NASA sponsored technology development can help.

  3. Vibration protection of radioelectronic equipment by polymer compounds

    NASA Astrophysics Data System (ADS)

    Zelenev, Iu. V.; Kirilin, A. A.; Slobodnik, E. B.; Talitskii, E. N.

    The use of well damped structures in combination with traditional methods provides a way to solve the problem of protecting radioelectronic equipment against vibration over a wide frequency range. An attempt is made here to generalize the available theoretical and experimental data on the use of polymer compounds for dispersing vibrational energy in the structures of radioelectronic equipment. Recommendations concerning the selection and design of single- and multilayer vibration-damping coatings and shock absorbers are given.

    Lakshminarasimha, Arkalgud N.; Rucigay, Richard J.; Ozgur, Dincer

    2003-01-01

    A machine protection system and method for rotating equipment introduces new alarming features and makes use of full proximity probe sensor information, including amplitude and phase. Baseline vibration amplitude and phase data is estimated and tracked according to operating modes of the rotating equipment. Baseline vibration and phase data can be determined using a rolling average and variance and stored in a unit circle or tracked using short term average and long term average baselines. The sensed vibration amplitude and phase is compared with the baseline vibration amplitude and phase data. Operation of the rotating equipment can be controlled based on the vibration amplitude and phase.

    Objective. To analyze and study astronaut and his personal equipment safety. Method. Three of the most widely used approaches, failure mode and effect analysis (FMEA), fault tree analysis (FTA) and system hazards analysis (SHA) were used. Result. It was demonstrated that astronaut and the personal equipment are subjected to various potential hazards, such as human errors, astronaut illness, fire or space suit emergency decompression, etc. Their causes, mechanisms, possible effects and criticality of some critical potential hazards were analyzed and identified in more details with considerations of the historic accidents of manned spaceflight. And the compensating provisions and preventive measures for each hazard were discussed. Conclusion. The analysis study may be helpful in enhancing the safety of the astronaut and its personal protective equipment. PMID:12434807

    Accurate identification of the hazardous material is essential for proper care. Efficient hospital security and triage must prevent contaminated victims from entering the emergency department (ED) and causing secondary contamination. The decontamination area should be located outside the ambulance entrance. Decontamination priorities are protection of the health care worker, utilization of Level C personal protective equipment, and proper decontamination of the exposed patient. Decontamination proceeds in a head-to-toe sequence. Run-off water is a hazardous waste. Hospital and Community Management Planning for these emergencies is essential for proper preparation and effective response to the hazardous materials incident. PMID:25455662

  18. Fuzzy clustering of facial form for prototyping environmental protection equipment

    SciTech Connect

    Robinson, D.G.

    1994-07-01

    Emphasis on the human-to-aircraft interface has magnified in importance as the performance envelope of today`s aircraft has continued to expand. A major problem is that there has been a corresponding increase in the need for better fitting protection equipment and unfortunately it has become increasingly difficult for aircrew members to find equipment that will provide this level of fit. While protection equipment has, historically had poor fit characteristics, the issue has grown tremendously with the recent increase in the numbers of minorities and women. Fundamental to this problem are the archaic methods for sizing individual equipment and the methods for establishing a sizing system. This paper documents recent investigations by the author into developing new methods to overcome these problems. Research centered on the development of a new statistically based method for describing form and the application of fuzzy clustering using the new shape descriptors. A sizing system was developed from the application of the research, prototype masks were constructed and the hardware tested under flight conditions.

    It has been revealed from the experiences of Decontamination and Decommissioning (D&D) activities that even a small improvement in performance can result in significant risk reduction and cost savings. For example, Race Scan Ear Mic System, which was originally developed for communications between racecar drivers and crews in loud environments, has been successfully applied to D&D work and proved to enhance worker safety and communications. Glovebox dismantlement is an important and costly process in D&D activities of nuclear facilities. Adequate decontamination and size reduction of the gloveboxes are especially important in this activity because they have the potential to reduce risks and costs significantly. This paper presents some simple approaches to support D&D tasks and discusses their potential advantages. Examples discussed include: Repeated shear wiping of large pipes and ducts; Application of thin layers on radiological counters for uninterrupted use; and Partial use of robotics for glovebox dismantling. The paper also discusses schematics for protecting equipment interiors and/or glovebox inner surfaces from contamination, which may result in significant savings and waste minimization upon future dismantlement. Examples discussed include: Smart coating for contamination prevention; and Protecting equipment by geometrically simple cover.

    The search for extraterrestrial life is one of the most challenging science topics for the next decades. Space missions, like ExoMars, plan to land and search for biological remnants on planets and moons in our nearby Solar system. Planetary protection regulations defined by COSPAR prevent that during the mission biological contamination of the bodies occur through the space probes. Therefore decontamination of the probes and more general space equipment is necessary before the launch. The up-to-date accepted decontamination procedure originate from the old NASA Viking missions and use dry heat (T>110°C for 30h) - a technology not well suited for sensitive equipment nowadays. We investigated in a study financed by the German Space Agency* cold atmospheric plasma (CAP) as an alternative for such decontamination. It is well known that CAP can kill bacteria or spores within seconds or minutes, respectively, if the plasma is in direct contact with the treated sample. This procedure might also be quite aggressive to the treated surface materials. Therefore, we developed an afterglow CAP device specially designed for the soft treatment of space equipment. Afterglow plasma produced by a SMD device in air is transported into a “larger” treatment chamber where the samples are positioned. It could be shown that samples of different bacteria and spores, the latter defined by COSPAR as a means to show the effectiveness of the decontamination process, positioned on different materials (steel, Teflon, quartz) could be effectively inactivated. The surface materials were investigated after the plasma treatment to identify etching or deposition problems. The afterglow in the treatment chamber could even overcome obstacles (tubes of different height and diameter) which simulate more complicated structures of the relevant surfaces. Up to now, CAP looks like a quite promising alternative to decontaminate space equipment and need to be studied in greater detail in the near future

  9. Personal protective equipment for registration purposes of pesticides.

    Regulatory authorities in North America, Europe and Australia use different approaches for the estimation of exposure reduction effectiveness of personal protective equipment (PPE) in registration processes of agrochemical pesticides. TNO has investigated current views and facts for the use of default values and set up a discussion paper which can be used as a starting point to achieve an internationally harmonised set of PPE protection factors for regulatory use. For inhalation exposure Loading it is proposed to use the assigned protection factors (APF) as deduced by BSI (British Standard Institution) and ANSI (American National Standards Institution). Since these values are somewhat variance and since in agricultural settings efficient control and proper training and education with respect to inhalation protection devices is generally absent, it is good to err on the safe side and to use the Lowest of both values, if available. For dermal exposure Loading differentiations are made for operators and re-entry workers and further for hand and body protection. Next to this the restrictions and framework for the use of the proposed defaults are very relevant. Oral exposure loading is only considered in special cases where dermal exposure may be relatively high and the hand-mouth shunt may lead to appreciable oral exposure loading. The presented defaults for PPE have been discussed with experts of regulatory authorities and industry, but a formal discussion still has to take place. This needs to be done on EU level between Member States. The current proposal is based on state-of-the-art knowledge and policy considerations, but further research is needed to better underpin the proposed values and/or to adapt them. PMID:18399428

    Waller, J. M.; Williams, J. H.

    1997-01-01

    Permeation resistance was determined by measuring the breakthrough time and time-averaged vapor transmission rate of monomethylhydrazine (MMH) through two types of personal protective equipment (PPE). The two types of PPE evaluated were the totally encapsulating ILC Dover Chemturion Model 1212 chemical protective suit with accessories, and the FabOhio polyvinyl chloride (PVC) splash garment. Two exposure scenarios were simulated: (1) a saturated vapor exposure for 2 hours (h), and (2) a brief MMH 'splash' followed by a 2-h saturated vapor exposure. Time-averaged MMH concentrations inside the totally-encapsulating suit were calculated by summation of the area-weighted contributions made by each suit component. Results show that the totally encapsulating suit provides adequate protection at the new 10 ppb Threshold Limit Value Time-Weighted Average (TLV-TWA). The permeation resistance of the PVC splash garment to MMH was poorer than any of the totally encapsulating suit materials tested. Breakthrough occurred soon after initial vapor or 'splash' exposure.

  1. Personnel protection equipment for use with laser chemicals

    Smith, I.D.; Roepke, J.

    1984-08-01

    The NASA White Sands Test facility (WSTF) recently built the fluid distribution system for the Army's High Energy Laser System Test Facility (HELSTF). As part of the effort, WSTF personnel were required to activate the fluorine system. To insure adequate personnel protection during the fluorine system activation, a project was undertaken to evaluate and qualify personnel protection equipment to be used during the activation (passivation) activity. Previous work in the late 60's and early 70's showed that very few materials were totally satisfactory for use with fluorine. Little if any work has been done to measure the degree of protection afforded against either fluorine gas or hydrofluoric acid (HF), the principal residual reactive material. Two general types of tests were conducted to evaluate materials. These were (1) fluorine and HF gas permeation tests, and (2) high-velocity fluorine gas-impingement tests. The gas permeation tests were designed to exposure one side of the material to the gas at concentrations of up to 27% F2 or 1.5% HF in designed to expose one side of the material to the gas at concentrations of up to 27% F2 or 1.5% HF in GN2 with a gas purge on the opposite side leading to the detection system. The tests showed that all of the materials tested which included ILC Dover Chloropel, glove materials - Neoprene, Viton, leather, butyl rubber, face shield materials, etc., where neither permeated by HF at a 1200 ppm level nor by F2 in GN2 at concentrations as high as 27% by volume. The gas-impingement tests were designed to represent a high-pressure gas leak or the cracking of a B-nut on a system containing residual fluorine gas.

  11. DEVELOPMENT OF PERSONAL PROTECTIVE EQUIPMENT FOR DECONTAMINATION AND DECOMMISSIONING

    SciTech Connect

    M.A. Ebadian, Ph.D.

    1999-01-01

    The purpose of this one-year investigation is to perform a technology integration/search, thereby ensuring that the safest and most cost-effective options are developed and subsequently used during the deactivation and decommissioning (D&D) of U.S. Department of Energy Environmental Management (DOE-EM) sites. Issues of worker health and safety are the main concern, followed by cost. Two lines of action were explored: innovative Personal Cooling Systems (PCS) and Personal Monitoring Equipment (PME). PME refers to sensors affixed to the worker that warn of an approaching heat stress condition, thereby preventing it. Three types of cooling systems were investigated: Pre-Chilled or Forced-Air System (PCFA), Umbilical Fluid-Chilled System (UFCS), and Passive Vest System (PVS). Of these, the UFCS leads the way. The PVS or Gel pack vest lagged due to a limited cooling duration. And the PCFA or chilled liquid air supply was cumbersome and required an expensive and complex recharge system. The UFCS in the form of the Personal Ice Cooling System (PICS) performed exceptionally. The technology uses a chilled liquid circulating undergarment and a Personal Protective Equipment (PPE) external pump and ice reservoir. The system is moderately expensive, but the recharge is low-tech and inexpensive enough to offset the cost. There are commercially available PME that can be augmented to meet the DOE's heat stress alleviation need. The technology is costly, in excess of $4,000 per unit. Workers easily ignore the alarm. The benefit to health & safety is indirect so can be overlooked. A PCS is a more justifiable expenditure.

    2009-10-01

    This study was one of a cluster of studies that originated via requests for proposals from the NIOSH National Agricultural Tractor Safety Initiative. The present study design consisted of several steps: (1) formation of an advisory group, (2) development and testing of a standard paper self-responding survey instrument, (3) sample selection of farm equipment dealers, (4) administration of the survey, (5) assessment and analysis of the survey, and (6) in-person response panel of dealers (n = 80) to review results of the questionnaire for further definition and sharpening of the recommendations from the survey. A key finding is that most dealers do not currently sell or install ROPS retrofit kits. Barriers cited by dealers included (1) actual or perceived lack of farmer demand, (2) injury liability, (3) expensive freight for ordering ROPS, (4) lack of dealer awareness of the magnitude of deaths from tractor overturns and the high life-protective factor of ROPS, and (5) difficulty and incursion of non-recoverable expenses in locating and obtaining specific ROPS. Despite not currently selling or installing ROPS, dealers responded favorably about their future potential role in ROPS promotion and sales. Dealers were willing to further promote, sell, and install ROPS if there was demand from farmers. Recommendations include establishing a ROPS "clearing house" that dealers could contact to facilitate locating and obtaining ROPS orders from customers. Additional recommendations include education and social marketing targeting farm machinery dealers as well farmers, manufacturers, and policy makers. PMID:19967910

    Understanding factors affecting the use of personal protective equipment (PPE) during handling of plant protection products (PPPs) is of major importance for the design of tailored interventions to minimize exposure among farmers. However, data regarding this issue are highly limited. Factors related to the use of PPE during handling of PPPs were explored in a survey of cotton farmers in northern Greece. Data were collected through face-to-face interviews with the farmers based on a questionnaire with structured items on the frequency of use of various personal protective devices during handling of PPPs. New evidence on patterns of PPE use and potential exposure of farmers to PPPs is provided. Most farmers (49.3%) showed potentially unsafe behaviour with respect to PPE use. Hat and boots were the most commonly used protective items during PPPs use, but most of the farmers surveyed reported low frequency of use for gloves, goggles, face mask, coveralls, and respirator. Especially the respirator was reported to be the least used PPE item amongst farmers. Farmers who perceived PPPs as harmful substances or those who had an episode of intoxication in the past reported more frequent use of several PPE items. Stepwise multiple regression analysis revealed that the variable episode of intoxication in the past exerted the strongest positive influence on PPE use, followed by the perception of PPPs being hazardous substances, upper secondary education, previous training on PPPs (i.e., spraying equipment, application parameters, risks to human health and environment, safety issues) and farm size under cultivation. Old age exerted a significant negative influence on PPE use, namely, elderly farmers tended not to use PPE. Strategies to maximize the protection of applicators of PPPs from hazardous exposures still require innovation to achieve increased effectiveness. Emphasis on lifelong training and education of farmers about hazards and risks of PPPs is crucial for changing

  16. Chest Compression With Personal Protective Equipment During Cardiopulmonary Resuscitation

    2016-01-01

    Abstract Following a chemical, biological, radiation, and nuclear incident, prompt cardiopulmonary resuscitation (CPR) procedure is essential for patients who suffer cardiac arrest. But CPR when wearing personal protection equipment (PPE) before decontamination becomes a challenge for healthcare workers (HCW). Although previous studies have assessed the impact of PPE on airway management, there is little research available regarding the quality of chest compression (CC) when wearing PPE. A present randomized cross-over simulation study was designed to evaluate the effect of PPE on CC performance using mannequins. The study was set in one university medical center in the China. Forty anesthesia residents participated in this randomized cross-over study. Each participant performed 2 min of CC on a manikin with and without PPE, respectively. Participants were randomized into 2 groups that either performed CC with PPE first, followed by a trial without PPE after a 180-min rest, or vice versa. CPR recording technology was used to objectively quantify the quality of CC. Additionally, participants’ physiological parameters and subjective fatigue score values were recorded. With the use of PPE, a significant decrease of the percentage of effective compressions (41.3 ± 17.1% with PPE vs 67.5 ± 15.6% without PPE, P < 0.001) and the percentage of adequate compressions (67.7 ± 18.9% with PPE vs 80.7 ± 15.5% without PPE, P < 0.001) were observed. Furthermore, the increases in heart rate, mean arterial pressure, and subjective fatigue score values were more obvious with the use of PPE (all P < 0.01). We found significant deterioration of CC performance in HCW with the use of a level-C PPE, which may be a disadvantage for enhancing survival of cardiac arrest. PMID:27057878

    SciTech Connect

    Not Available

    1988-01-31

    Two laws governing activities in the marine environment are considered in this Reference Book. The Marine Protection, Research, and Sanctuaries Act (MPRSA, P.L. 92-532) regulates ocean dumping of waste, provides for a research program on ocean dumping, and provides for the designation and regulation of marine sanctuaries. The Marine Mammal Protection Act (MMPA, P.L. 92-522) establishes a federal program to protect and manage marine mammals. The Fishery Conservation and Management Act (FCMA, P.L. 94-265) establishes a program to regulate marine fisheries resources and commercial marine fishermen. Because the Department of Energy (DOE) is not engaged in any activities that could be classified as fishing under FCMA, this Act and its regulations have no implications for the DOE; therefore, no further consideration of this Act is given within this Reference Book. The requirements of the MPRSA and the MMPA are discussed in terms of their implications for the DOE.

  19. Using interactive computer simulation for teaching the proper use of personal protective equipment.

    PubMed

    Hung, Pan-Pan; Choi, Kup-Sze; Chiang, Vico Chung-Lim

    2015-02-01

    The use of personal protective equipment is one of the basic infection control precautions in health care. The effectiveness of personal protective equipment is highly dependent on adequate staff training. In this project, a computer simulation program, as a supplement to conventional training approaches, was developed to facilitate the learning of the proper use of personal protective equipment. The simulation program was a Web-based interactive software with user-friendly graphical interface for users to practice the use of personal protective equipment usage via drag-and-drop metaphors and respond to questions online. The effectiveness of the computer simulation software was investigated by a controlled study. Fifty healthcare workers were randomly assigned into two groups: one received conventional personal protective equipment training only (control group), whereas the other also received the same conventional training but followed by using the developed simulation program for self-learning (experimental group). Their performance was assessed by personal protective equipment donning and doffing evaluation before and after the training. The results showed that the computer simulation program is able to improve the healthcare workers' understanding and competence in using personal protective equipment. PMID:25521788

  20. Considerations for selecting personal protective equipment for hazardous materials decontamination.

    PubMed

    Lehmann, Jeff

    2002-09-01

    PPE is necessary to protect staff and to deliver rapid and efficient care to patients contaminated with HAZMAT chemicals. Planning for HAZMAT cases includes learning about the common chemicals in the area, what resources are available to care for victims, identifying a decontamination area, and providing PPE to protect employees and other patients. A customized service can be used to meet OSHA standards and reduce costs. Ongoing training will be an important part of any HAZMAT program. PMID:12685463

  1. Effect of firefighters' personal protective equipment on gait.

    PubMed

    Park, Huiju; Kim, Seonyoung; Morris, Kristen; Moukperian, Melissa; Moon, Youngjin; Stull, Jeffrey

    2015-05-01

    The biomechanical experiment with eight male and four female firefighters demonstrates that the effect of adding essential equipment: turnout ensemble, self-contained breathing apparatus, and boots (leather and rubber boots), significantly restricts foot pronation. This finding is supported by a decrease in anterior-posterior and medial-lateral excursion of center of plantar pressure (COP) trajectory during walking. The accumulation of this equipment decreases COP velocity and increases foot-ground contact time and stride time, indicating increased gait instability. An increase in the flexing resistance of the boots is the major contributor to restricted foot pronation and gait instability as evidenced by the greater decrease in excursion of COP in leather boots (greater flexing resistance) than in rubber boots (lower resistance). The leather boots also shows the greatest increase in foot contact time and stride time. These negative impacts can increase musculoskeletal injuries in unfavorable fire ground environments.

    Reading books and watching films were investigated as protective factors for serious suicidal ideation (SSI) in young people with low perceived social belonging. Cross-sectional and longitudinal (12-month) analyses were performed using data from a representative European sample of 3256 students from the “Saving and Empowering Young Lives in Europe” study. Low social belonging was associated to SSI. However, reading books and watching films moderated this association, especially for those with lowest levels of belonging. This was true both at baseline and at 12 months of follow-up analyses. These media may act as sources of social support or mental health literacy and thus reduce the suicide risk constituted by low sense of belonging. PMID:26694431

  15. Protection of VHF international distress frequencies from harmonic radiation due to digital television equipment

    NASA Astrophysics Data System (ADS)

    Middleton, J.

    Digital television picture processing equipment uses a luminance sampling frequency of 13.5 MHz, which can give rise to harmonics at 121.5 and 243 MHz. If such equipment becomes sufficiently widespread as will probably be the case with MAC/packet receivers, it is possible that the cumulative radiation could become significantly high. Since these frequencies are used by the international distress services there is a potential for interference if this unwanted radiation is not controlled at the point of manufacture. Over the last two years this problem was studied by the BBC in conjunction with the EBU. The conclusion is that the distress services will be protected provided that digital television picture processing equipment meets existing electromagnetic compatibility (EMC) standards for information technology equipment. In the case of domestic television this should not present a problem, but for studio equipment, because of its size and complexity, EMC compliance may not be so easy.

  16. Personal Protective Equipment for Filovirus Epidemics: A Call for Better Evidence

    Sprecher, Armand G.; Caluwaerts, An; Draper, Mike; Feldmann, Heinz; Frey, Clifford P.; Funk, Renée H.; Kobinger, Gary; Le Duc, James W.; Spiropoulou, Christina; Williams, Warren Jon

    2015-01-01

    Personal protective equipment (PPE) is an important part of worker protection during filovirus outbreaks. The need to protect against a highly virulent fluid-borne pathogen in the tropical environment imposes a heat stress on the wearer that is itself a safety risk. No evidence supports the choice of PPE employed in recent outbreaks, and standard testing procedures employed by the protective garment industry do not well simulate filovirus exposure. Further research is needed to determine the appropriate PPE for filoviruses and the heat stress that it imposes. PMID:25821225

  2. A description of factors affecting hazardous waste workers' use of respiratory protective equipment

    SciTech Connect

    Salazar, M.K.; Takaro, T.K.; Connon, C.; Ertell, K.; Pappas, G.; Barnhart, S.

    1999-07-01

    This article describes the first phase of a study that was designed to gain an understanding of hazardous waste workers' attitudes and beliefs about the use of respiratory protective equipment. Exploratory, open-ended interviews were conducted among 28 respirator users at a US Department of Energy facility. Subjects were asked to describe their knowledge, attitudes, and beliefs about their risks to hazards at their worksites and to discuss their use of respiratory protective equipment. A detailed content analysis of the interviews resulted in the generation of a taxonomy of issues and concerns which fell into three general categories: (1) Knowledge, Beliefs, and Attitudes, (2) Physical and Psychological Effects, and (3) External Influences. Knowledge, Beliefs, and Attitudes included Training, Fit Testing, Medical Clearance, Work Exposures, Respirator Use, and Vulnerability to Disease. Physical and Psychological Effects included Somatic/Health Effects, Personal Comfort, Visual Effects, Fatigue, Communication, and Anxiety. External Influences included Structural Environment, Quality and Availability of Equipment, Other PPEs, Co-Worker Influence, Supervisor Influence, and Organizational Culture. The findings from this study have important implications to training and education programs. Effective respiratory protection programs depend on a knowledge of the factors that affect workers' use of equipment. This study suggests that efforts to assure equipment comfort and fit, to assist workers who see and hear less well as a result of their equipment, and to develop strategies to allay worker anxiety when wearing equipment should all be components of a program. An organizational culture that supports and abets the appropriate use of equipment is also a critical element in a successful program.

    The purpose of this study was to examine the impact of undergarment composition worn beneath ice hockey protective equipment on thermal homeostasis and power output, during a cycle ergometer exercise protocol designed to simulate the energy expenditure of a hockey game. We hypothesized that the layers of protective equipment would negate the potential thermoregulatory benefits from synthetic "wicking" undergarments but that subjects may feel more comfortable because of the inherent low moisture retention of these fabrics. Eight men (age, 25.4 ± 1.3 year) performed a repeated sprint test before and after a simulated game under typical hockey conditions (12°C; 82% relative humidity). This test was completed twice while wearing full protective equipment and either synthetic (SYN) or cotton (COT) full-length undergarments. During the simulated game, skin temperatures (34.22 ± 0.20°C vs. 34.46 ± 0.16°C) and core temperatures (37.50 ± 0.13°C vs. 37.59 ± 0.14°C) were similar between SYN and COT, respectively. There were also no significant differences found in sweat loss as a percent of body mass, heart rate, plasma lactate, sprint power, or ratings of perceived exertion between SYN and COT, respectively. The SYN retained less water than COT (140 ± 30 vs. 310 ± 30 g; p < 0.05); however, clothing and protective equipment weight gains as a whole were unaffected by the fabric worn (470 ± 110 vs. 590 ± 80 g) for SYN and COT, respectively. There were minimal differences in thermal sensation and undergarment wetness ratings during the simulated game. Thermoregulation and performance was driven more by properties of the layered protective equipment with minimal effects from undergarment composition. PMID:22706578

  1. How to protect the Earth from Global warming by means of Sunlight Shield Equipments

    The Earth is getting warmer because excess carbon dioxide of the Earth's atmosphere. Many studies are proceeding in the world in order to prevent global warming. Three methods are studied: (1) How to reduce carbon dioxide of the Earth's atmosphere. For example, more trees will be planted and carbon dioxide is changed to oxygen and carbon. (2) How to reduce carbon dioxide emission that human activity makes. (3) How to protect the Earth from global warming. The first or the second method has been studied, and they do not immediately protect the Earth from global warming. On the other hand the third method has an immediate effect. Sunlight shield effects of a cloud or tiny sulfur in the air have been studied. The author has proposed a sunlight shield equipment which is composed of a flat balloon. Balloon's surface has a mirror function. The sunlight shield equipment is set at the stratosphere and its surface reflects sunlight to the space. It is different temperature between daytime and night time, because the earth is heated by the sun during only daytime. Temperature of the Earth could be controlled by controlling an amount of a sunlight power which the earth receives from the sun. In other word, when many sunlight shield equipments are set and operated at the stratosphere, and an amount of sunlight, which the earth receives from the sun, could be controlled. For example, when an amount of the sunlight power, which the earth receives, decreases one percent, a mean value of the earth temperature deceases about one centigrade. In order to decrease one percent of a sunlight power which the earth receives, it is required that many sunlight shield equipments are distributively set and operated, and the gross area of many sunlight shield equipments is equal to 5,060,000 km squares. When a size of a sunlight shield equipment is equal to 5 km squares, about one million of sunlight shield equipments are necessary, and a large scale of cost is required. Therefore, an

    This Compliance Program Guidance Package identifies the regulatory guidance and industry codes and standards addressing radiation protection equipment, instrumentation, and support facilities considered to be appropriate for radiation protection at the Monitored Geologic Repository (MGR). Included are considerations relevant to radiation monitoring instruments, calibration, contamination control and decontamination, respiratory protection equipment, and general radiation protection facilities. The scope of this Guidance Package does not include design guidance relevant to criticality monitoring, area radiation monitoring, effluent monitoring, and airborne radioactivity monitoring systems since they are considered to be the topics of specific design and construction requirements (i.e., ''fixed'' or ''built-in'' systems). This Guidance Package does not address radiation protection design issues; it addresses the selection and calibration of radiation monitoring instrumentation to the extent that the guidance is relevant to the operational radiation protection program. Radon and radon progeny monitoring instrumentation is not included in the Guidance Package since such naturally occurring radioactive materials do not fall within the NRC's jurisdiction at the MGR.

    This chapter describes the most important features of capillary electrophoretic equipment. A presentation of the important developments in high voltage power supplies for chip CE is followed by preparation of fused silica capillaries for use in CE. Detection systems that are used in capillary electrophoresis are widely described. Here, UV-Vis absorbance measurements are discussed including different types of detection cells—also those less popular (u-shaped, Z-shaped, mirror-coated). Fluorescence detection and laser-induced fluorescence detection are the most sensitive detection systems. Several LIF setups, such as collinear, orthogonal, confocal, and sheath-flow cuvette, are presented from the point of view of the sensitivity they can provide. Several electrochemical detectors for CE, such as conductivity, amperometric, and potentiometric, are also shown and their constructions discussed. CE-MS and much less known CE (CEC)-NMR systems are also described. The examples of automation and robotized CE systems together with their potential fields of application are also presented.

    As advances in protective equipment are made, it has been observed that the weight law enforcement officers must carry every day is greatly increasing. Many investigations have noted the health risks of these increases, yet none have looked at its effects on officer mobility. The primary purpose of this study was to examine the influence of both the weight of officer safety equipment, as well as a lateral focal point (FP), on the stride length, stride velocity, and acceleration of the first six strides of a short sprint. Twenty male law enforcement students performed two maximal effort sprint trials, in the participating college's gymnasium, from each of four starting positions: forwards (control position), backwards, 90° left, and 90° right. Subjects placed in the FP group (n = 9) were required to maintain focus on lateral FP during the 90° left and 90° right trials, and a forwards FP during the backwards trials. On a second testing date, subjects repeated the sprint tests while wearing a 9.07 kg weight belt, simulating officer equipment and protective gear. The belt averaged 11.47 ± 1.64% of subject body mass. A significant main effect of weight belt trials was found (F = 20.494, p < 0.01), in which significant decreases were found for velocity and acceleration. No other significant effects were found as a result of starting position or focal point and no significant interactions were found between independent variables. Conclusively, the results of this study show the increasing weights of duty gear and protective equipment have detrimental effects on officer velocity and acceleration, impeding their mobility, which may be dangerous in use of force or threatening situations.

    The protection of health care facility (HCF) staff from the effects of weapons of mass destruction has gained heightened attention since the 9-11 terrorist attacks. One critical component of protection is personal protective equipment (PPE). No universal standard exists for an "essential" level of PPE for HCF staff. The absence of such a standard raises the need for development of national policy for PPE levels, particularly in HCFs. We describe a process used by the Veterans Health Administration for recommending policy for "essential" PPE levels. Although the recommendations are specific for Veterans Health Administration, the process, findings, and applications may be useful to other institutions as they attempt to resolve this critical issue. This descriptive account will serve to generate practical scientific debate in the academic community and lead to definitive public policy recommendations for the Nation's HCFs in executing their roles in the event of a terrorist attack.

    Simple Summary The handling and riding of horses can be quite dangerous. Although the use of protective gear among equestrians is increasing, a high number of incidents occur and the voluntary use of safety equipment is described as inconsistent to low. Therefore, this study looks at the safety behavior of German equestrians and at factors influencing this behavior to decrease the high number of horse-related injuries. The results reveal that attitudes towards safety products as well as the protective behavior of other horse owners and riding pupils from the stable are key factors that might alter the safety behavior of equestrians. Abstract Human interactions with horses entail certain risks. Although the acceptance and use of protective gear is increasing, a high number of incidents and very low or inconsistent voluntary use of safety equipment are reported. While past studies have examined factors influencing the use of safety gear, they have explored neither their influence on the overall safety behavior, nor their relative influence in relation to each other. The aim of the present study is to fill this gap. We conducted an online survey with 2572 participants. By means of a subsequent multiple regression analysis, we explored 23 different variables in view of their influence on the protective behavior of equestrians. In total, we found 17 variables that exerted a significant influence. The results show that both having positive or negative attitudes towards safety products as well as the protective behavior of other horse owners or riding pupils from the stable have the strongest influence on the safety behavior of German equestrians. We consider such knowledge to be important for both scientists and practitioners, such as producers of protective gear or horse sport associations who might alter safety behavior in such a way that the number of horse-related injuries decreases in the long term.

    2015-01-01

    Connectors are commonly found in personal equipment protecting against falls from a height. They are typically used outdoors and exposed to atmospheric factors, which can result in corrosion. This article presents the results of a study involving exposure of connectors to experimental corrosive media - neutral salt spray (NSS), acid salt spray (ASS), and seawater mist (for elements made of carbon steel and non-ferrous metals) - and to experimental conditions simulating the processes of pitting, stress, and intercrystalline corrosion (for equipment made of s`tainless steel). The results indicate that the main effects of corrosion on connectors include impaired operation and reduced strength of their mobile elements. The article presents methods of testing connector operation developed for this purpose. Corrosive damage to connectors has been presented in relation to potential hazards for their users.

    The 'control banding' approach in COSHH Essentials combines the potential for harm with the potential for exposure by inhalation to band measures to control exposure at source, as generic strategies. These are simply adapted to specific tasks and circumstances to produce specific control advice. Where it is not possible or practical to use this control advice, the control bands can suggest adequate respiratory protective equipment using 'protection factors'. Proposals in the paper enable the user to identify the right level of respiratory protective equipment (RPE), and to begin selecting suitable RPE. Selection is made through a formatted questionnaire, enabling the user to give the right facts to the supplier. COSHH Essentials applies mainly to exposure by inhalation. However, skin exposure is very common and uptake via the skin can be an important contributor to body dose. This paper examines the factors concerning skin exposure, and the options for banding the potential for harm to the skin or via the skin. Proposals have then been made for dermal exposure control. Planning for emergencies is an important facet of risk control. Proposals are outlined to band chemical hazards for emergency planning according to a minimum of information, i.e. the danger symbol on a product label. PMID:14530184

    Objectives This study aimed to compare visualisation of the vocal cords and performance of intubation by anaesthetists using four different laryngoscopes while wearing full chemical protective equipment. Setting Medical simulation center of a university hospital, department of anaesthesiology. Participants 42 anaesthetists (15 females and 27 males) completed the trial. The participants were grouped according to their professional education as anaesthesiology residents with experience of <2 years or <5 years, or as anaesthesiology specialists with experience of >5 years. Interventions In a manikin scenario, participants performed endotracheal intubations with four different direct and indirect laryngoscopes (Macintosh (MAC), Airtraq (ATQ), Glidescope (GLS) and AP Advance (APA)), while wearing chemical protective gear, including a body suit, rubber gloves, a fire helmet and breathing apparatus. Primary and secondary outcome measures With respect to the manikin, setting time to complete ‘endotracheal intubation’ was defined as primary end point. Glottis visualisation (according to the Cormack-Lehane score (CLS) and impairments caused by the protective equipment, were defined as secondary outcome measures. Results The times to tracheal intubation were calculated using the MAC (31.4 s; 95% CI 26.6 to 36.8), ATQ (37.1 s; 95% CI 28.3 to 45.9), GLS (35.4 s; 95% CI 28.7 to 42.1) and APA (23.6 s; 95% CI 19.1 to 28.1), respectively. Intubation with the APA was significantly faster than with all the other devices examined among the total study population (p<0.05). A significant improvement in visualisation of the vocal cords was reported for the APA compared with the GLS. Conclusions Despite the restrictions caused by the equipment, the anaesthetists intubated the manikin successfully within adequate time. The APA outperformed the other devices in the time to intubation, and it has been evaluated as an easily manageable device for anaesthetists with varying

    The misuse of personal protective equipment (PPE) during pesticide application was investigated among smallholders in Colombia. The integrative agent-centered (IAC) framework and a logistic regression approach were adopted. The results suggest that the descriptive social norm was significantly influencing PPE use. The following were also important: (1) having experienced pesticide-related health problems; (2) age; (3) the share of pesticide application carried out; and (4) the perception of PPE hindering work. Interestingly, the influence of these factors differed for different pieces of PPE. Since conformity to the social norm is a source of rigidity in the system, behavioral change may take the form of a discontinuous transition. In conclusion, five suggestions for triggering a transition towards more sustainable PPE use are formulated: (1) diversifying targets/tools; (2) addressing structural aspects; (3) sustaining interventions in the long-term; (4) targeting farmers' learning-by-experience; and (5) targeting PPE use on a collective level.

    Economizer use in data centers is an energy efficiency strategy that could significantly limit electricity demand in this rapidly growing economic sector. Widespread economizer implementation, however, has been hindered by potential equipment reliability concerns associated with exposing information technology equipment to particulate matter of outdoor origin. This study explores the feasibility of using economizers in data centers to save energy while controlling particle concentrations with high-quality air filtration. Physical and chemical properties of indoor and outdoor particles were analyzed at an operating northern California data center equipped with an economizer under varying levels of air filtration efficiency. Results show that when improved filtration is used in combination with an economizer, the indoor/outdoor concentration ratios for most measured particle types were similar to levels when using conventional filtration without economizers. An energy analysis of the data center reveals that, even during the summer months, chiller savings from economizer use greatly outweigh any increase in fan power associated with improved filtration. These findings indicate that economizer use combined with improved filtration could reduce data center energy demand while providing a level of protection from particles of outdoor origin similar to that observed with conventional design.

    Human interactions with horses entail certain risks. Although the acceptance and use of protective gear is increasing, a high number of incidents and very low or inconsistent voluntary use of safety equipment are reported. While past studies have examined factors influencing the use of safety gear, they have explored neither their influence on the overall safety behavior, nor their relative influence in relation to each other. The aim of the present study is to fill this gap. We conducted an online survey with 2572 participants. By means of a subsequent multiple regression analysis, we explored 23 different variables in view of their influence on the protective behavior of equestrians. In total, we found 17 variables that exerted a significant influence. The results show that both having positive or negative attitudes towards safety products as well as the protective behavior of other horse owners or riding pupils from the stable have the strongest influence on the safety behavior of German equestrians. We consider such knowledge to be important for both scientists and practitioners, such as producers of protective gear or horse sport associations who might alter safety behavior in such a way that the number of horse-related injuries decreases in the long term.

    Sporting activities have an inherent risk of facial injury from traumatic impacts from fellow competitors, projectiles, and collisions with posts or the ground. This retrospective review systematically describes the interplay between the type of sport (including the level at which specific sports are played), the sex of the players and their musculoskeletal characteristics, the technology behind the materials used, the protective devices commonly used, the anatomical site, and the regularity of incidence of fractures. We describe how variations in sporting activities induce different orofacial fracture patterns, and critically consider the methods used to test protective headgear against more contemporary techniques. Facial injuries can have a profound psychological effect on those injured, can take a long time to heal, and have been known to end promising careers. Use of properly fitted protective head or facial equipment could reduce the number of facial fractures commonly seen in sports. We recommend that individual sports should have full risk assessments, and that mandatory standards should be agreed about protective devices that would be appropriate. PMID:21295384

    To study the effects of an intervention based on social marketing to persuade workers to use personal protective equipment (PPE) in constructing subway stations in Isfahan, Iran. This was a quasi-experimental study. Two stations were selected as intervention and control groups. Intervention was designed based on results of a formative research. A free package containing a safety helmet with a tailored message affixed to it, mask and gloves and an educational pamphlet was delivered to the intervention group. After 6 weeks, behaviours in the intervention and control stations were measured using an observational checklist. After the intervention, the percentage of workers who used PPE at the intervention station increased significantly. OR for helmet and mask usage was 7.009 and 2.235, respectively, in the intervention group. Social marketing can be used to persuade workers to use PPE in the workplace. PMID:25873072

    In a metal refining plant, 366 workers were interviewed to investigate factors contributing to the discomfort or dissatisfaction of wearing personal protective equipment (PPE). Up to 97.8% of these individuals used one or more types of PPE. The percentages of employees who reported their hard hats and cooling vests as comfortable were 17% and 19%, respectively. Twenty-five percent of workers felt their respirators and safety harnesses were comfortable. Safety glasses ranked at 50%, gloves 53%, and safety shoes 54% for comfort factor. The percentage of employees who tolerated their PPE (just acceptable) ranged from 27% to 52%. The most frequently cited factors contributing to discomfort or dissatisfaction of wearing PPE were related to the workers' beliefs that the PPE was not needed, created a new hazard, interfered with work, was too heavy, was hard to wear, prohibited breathing or communicating, irritated skin, put pressure on the body, and was of an undesirable type or model.

    A 420 kV High-Voltage Alternating Current Circuit-Breaker, a typical element of an open-air electrical substation, is considered. Experimental tests carried out on such a piece of equipment by ISMES, under ENEL support, clearly pointed out its inability to withstand the seismic qualification level of highest severity indicated by the standards. The design of a seismic isolation system for the switch-gear composed of spring units and dampers is developed in this paper, and the dynamic earthquake response of the isolated circuit-breaker is compared numerically to the one obtained without the seismic protection system. The remarkable reduction of stresses in the porcelain insulators are shown, evidencing that this occurs to the detriment of a certain increment of displacements at the top of the apparatus.

    2004-11-01

    This document takes the newly released Industrial Hygiene Chemical Vapor Technical Basis (RPP-22491) and evaluates the chemicals of potential concern (COPC) identified for selected implementation actions by the industrial hygiene organization. This document is not intended as a hazard analysis with recommended controls for all tank farm activities. Not all of the chemicals listed are present in all tanks; therefore, hazard analyses can and should be tailored as appropriate. Detection of each chemical by current industrial hygiene non-specific instrumentation in use at the tank farms is evaluated. Information gaps are identified and recommendations are made to resolve these needs. Of the 52 COPC, 34 can be detected with existing instrumentation. Three additional chemicals could be detected with a photoionization detector (PID) equipped with a different lamp. Discussion with specific instrument manufacturers is warranted. Consideration should be given to having the SapphIRe XL customized for tank farm applications. Other instruments, sampling or modeling techniques should be evaluated to estimate concentrations of chemicals not detected by direct reading instruments. In addition, relative instrument response needs to be factored in to action levels used for direct reading instruments. These action levels should be correlated to exposures to the COPC and corresponding occupational exposure limits (OELs). The minimum respiratory protection for each of the COPC is evaluated against current options. Recommendations are made for respiratory protection based on each chemical. Until exposures are sufficiently quantified and analyzed, the current use of supplied air respiratory protection is appropriate and protective for the COPC. Use of supplied air respiratory protection should be evaluated once a detailed exposure assessment for the COPC is completed. The established tank farm OELs should be documented in the TFC-PLN-34. For chemicals without an established tank farm OEL

    Ten men (non-firefighters) completed a 110 min walking/recovery protocol (three 20-min exercise bouts, with recovery periods of 10, 20, and 20 min following successive bouts) in a thermoneutral laboratory while wearing firefighting personal protective equipment over one of four base layers: cotton, modacrylic, wool, and phase change material. There were no significant differences in changes in heart rate, core temperature, rating of perceived exertion, thermal discomfort, and thermal strain among base layers. Sticking to skin, coolness/hotness, and clothing humidity sensation were more favorable (p < 0.05) for wool compared with cotton; no significant differences were identified for the other 7 clothing sensations assessed. Separate materials performance testing of the individual base layers and firefighting ensembles (base layer + turnout gear) indicated differences in thermal protective performance and total heat loss among the base layers and among ensembles; however, differences in heat dissipation did not correspond with physiological responses during exercise or recovery.

    2014-01-01

    The recent Ebola virus disease (EVD) outbreak has created interest in personal protective equipment (PPE) content and usage. PPE testing has historically been done by individual component, rather than as a bundle for contact isolation. Fluorescent agents are commonly used in training for infection control techniques. The purpose of our study was to compare 2 PPE bundles and to evaluate the feasibility of fluorescent markers as an assessment tool for PPE effectiveness. Eight healthcare providers volunteered for this preliminary study. Participants were randomized to 1 of 2 PPE bundles that meet current (October 20, 2014) CDC recommendations. One PPE bundle utilized commercial EVD-recommended components. The other PPE bundle used components already available at local hospitals or retail stores. Participants were also randomized to standard or high volume exposures (HVE) to simulate fluid splash. Each participant was assisted in PPE donning and doffing by an experienced trainer. A training mannequin was contaminated with fluorescent agents to simulate bodily fluids. Participants were then given clinical tasks to care for the EVD “patient.” De-gowned participants were examined under “black light” for fluorescence indicative of contamination. One participant in each PPE arm had evidence of contamination. One of the contamination events was suspected during the patient care exercise. The other contamination event was not suspected until black light examination. In spite of a large difference in cost of PPE, the two bundle arms performed similarly. Bundle testing using fluorescent markers could help identify optimal PPE systems. PMID:26793445

    OBJECTIVE To identify issues during donning and doffing of personal protective equipment (PPE) for infectious diseases and to inform PPE procurement criteria and design. DESIGN A mixed methods approach was used. Usability testing assessed the appropriateness, potential for errors, and ease of use of various combinations of PPE. A qualitative constructivist approach was used to analyze participant feedback. SETTING Four academic health sciences centers: 2 adult hospitals, 1 trauma center, and 1 pediatric hospital, in Toronto, Canada. PARTICIPANTS Participants (n=82) were representative of the potential users of PPE within Western healthcare institutions. RESULTS None of the tested combinations provided a complete solution for PPE. Environmental factors, such as anteroom layout, and the design of protocols and instructional material were also found to impact safety. The study identified the need to design PPE as a complete system, rather than mixing and matching components. CONCLUSIONS Healthcare institutions are encouraged to use human factors methods to identify risk and failure points with the usage of their selected PPE, and to modify on the basis of iterative evaluations with representative end users. Manufacturers of PPE should consider usability when designing the next generation of PPE. Infect Control Hosp Epidemiol 2016;37:1022-1028. PMID:27291787

    Personal protective equipment (PPE) frequently is used to reduce the risk of spreading adventitial diseases in rodent colonies. The PPE worn often reflects the historic practices of the research institution rather than published performance data. Standard PPE for a rodent facility typically consists of a disposable hair bonnet, gown, face mask, shoe covers, and gloves, which are donned on facility entry and removed on exiting. This study evaluated the effect of a reduced PPE protocol on disease spread within an endemically infected mouse colony. In the reduced protocol, only the parts of the wearer that came in direct contact with the mice or their environment were covered with PPE. To test the reduced PPE protocol, proven naïve mice were housed in a facility endemically infected with murine norovirus and mouse hepatitis virus for 12 wk. During that time, routine husbandry operations were conducted by using either the standard or reduced PPE protocols. All study mice remained free of virus antibody when reduced PPE was implemented. These results indicate that reduced PPE is adequate for disease containment when correct techniques for handling microisolation caging are used. Reducing the amount of PPE used in an animal facility affords considerable cost savings yet limits the risk of disease spread. PMID:24827569

    The National Aeronautics and Space Administration (NASA) places highest priority on the safety of its astronauts and support personnel. Because this is so, and to ensure the continuation of this safety, the agency has undertaken to thoroughly research and develop and provide personal protective equipment (PPE) and individual life support systems (LSS) in support of manned spaceflight. It is probable that technology developed for manned spaceflight in the field of PPE and individual LSS can be utilized in certain industrial/commercial endeavors. In an attempt to determine these other uses for this PPE and individual LSS, the Space Suit Systems Branch of the NASA JSC Crew Systems Division initiated a research project designed to access potential common technology that could benefit industry. Such dual-use technology transfer could eventually involve a joint effort by Government and industry. The research project took place over several months and involved discussions with various manufacturers/suppliers/users, as well as regulatory agencies and industries, of PPE and individual LSS. Research data was compiled and evaluated and a summary of significant findings is presented for identifying and establishing opportunities for future cooperation between Government and industry in the field of PPE and individual LSS.

    This descriptive cross-sectional study examines the compliance of workers from the European Gaseous Diffusion Uranium Enrichment Consortium (EURODIF) with personal protection equipment (PPE) in view of the various hazards in the nuclear fuel industry. The PPE inventory was drawn up by an industrial hygienist in charge of the PPE at EURODIF. Two hundred and twenty seven (10%) randomly selected, active and retired, EURODIF workers filled in a questionnaire on their attitudes towards PPE. Exposure data from the EURODIF job exposure matrix were used to examine whether PPE usage varies according to exposure level. The study suggests a PPE usage profile that varies depending on the hazards present and PPE available. Anti-uranium PPE and gloves were among the best rated, while anti-spray goggles were the least used. We found that, for most hazards known to cause cancer or irreversible health damage, PPE usage varied according to exposure (homogeneity test, p<0.05; trend test, p<0.05). The continuous use of PPE among workers should be encouraged through improvements to the PPE management system. A precise model of individual exposure can only be designed if the use and efficiency of PPE are taken into consideration. PMID:23819938

    Hearing loss from occupational noise exposure is a significant occupational health problem, requiring effective health and safety strategies. Essential to this is an understanding of the noise exposure of workers and the use of hearing protection equipment (HPE). This study reports on data collected in New Zealand. Visits were made to companies in each economic sector. Personal dosimetry was used to assess individual noise exposure of 529 workers. Workers were also interviewed about their use of HPE. Overall, 40.4% of production workers had a daily noise exposure greater than 1 Pa(2)h, exceeding the New Zealand National Standard for occupational noise exposure without HPE. Of these, 88.5% reported to use HPE when working in noise; however, some observations suggested that workers do not consistently use the devices. These data add to the overall picture of noise exposure of workers in New Zealand and are especially useful in areas where data did not previously exist or were difficult to access. PMID:24205958

    Recognition by the US Army that a potential threat to the public from continued storage was potentially as great a threat as from transportation and the final demilitarization of chemical agents gave rise to the Chemical Stockpile Emergency Preparedness Program (CSEPP). CSEPP is a civilian community emergency preparedness program complementing the Department of Defense`s initiative to destroy domestic stockpiles of aged chemical warface munitions. An incident involving chemical warfare agents requires a unique hazardous materials (HAZMAT) response. As with any HAZMAT event, federal regulations prescribe that responders must be protected from exposure to the chemical agents. But unlike other HAZMAT events, special considerations govern the selection of personal protective equipment (PPE). PPE includes all clothing, respirators and detection equipment used to respond to a chemical release. PPE can differ depending on whether responders are military or civilian personnel. FEMA requested that ORNL create training materials for CSEPP participants. These training materials were to provide information on a variety of topics and answer questions that a typical CSEPP participant might ask, including the following: how did the Army select the CSEPP recommended ensemble (i.e., protective clothing, respiratory equipment, and detection equipment); how does the CSEPP participant know this ensemble is the right PPE for chemical warfare agents and will actually protect him; what are the concept of operations and work rules? Does one need to know what the CSEPP concept of operations and work rules include? This report describes the training document ORNL created.

    2016-01-01

    This article describes the evaluation of an open-access web-based respiratory protective equipment selector tool (RPE-Select, accessible at http://www.healthyworkinglives.com/rpe-selector). This tool is based on the principles of the COSHH-Essentials (C-E) control banding (CB) tool, which was developed for the exposure risk management of hazardous chemicals in the workplace by small and medium sized enterprises (SMEs) and general practice H&S professionals. RPE-Select can be used for identifying adequate and suitable RPE for dusts, fibres, mist (solvent, water, and oil based), sprays, volatile solids, fumes, gases, vapours, and actual or potential oxygen deficiency. It can be applied for substances and products with safety data sheets as well as for a large number of commonly encountered process-generated substances (PGS), such as poultry house dusts or welding fume. Potential international usability has been built-in by using the Hazard Statements developed for the Globally Harmonised System (GHS) and providing recommended RPE in picture form as well as with a written specification. Illustration helps to compensate for the variabilities in assigned protection factors across the world. RPE-Select uses easily understandable descriptions/explanations and an interactive stepwise flow for providing input/answers at each step. The output of the selection process is a report summarising the user input data and a selection of RPE, including types of filters where applicable, from which the user can select the appropriate one for each wearer. In addition, each report includes ‘Dos’ and ‘Don’ts’ for the recommended RPE. RPE-Select outcomes, based on up to 20 hypothetical use scenarios, were evaluated in comparison with other available RPE selection processes and tools, and by 32 independent users with a broad range of familiarities with industrial use scenarios in general and respiratory protection in particular. For scenarios involving substances having safety

This tool is based on the principles of the COSHH-Essentials (C-E) control banding (CB) tool, which was developed for the exposure risk management of hazardous chemicals in the workplace by small and medium sized enterprises (SMEs) and general practice H&S professionals. RPE-Select can be used for identifying adequate and suitable RPE for dusts, fibres, mist (solvent, water, and oil based), sprays, volatile solids, fumes, gases, vapours, and actual or potential oxygen deficiency. It can be applied for substances and products with safety data sheets as well as for a large number of commonly encountered process-generated substances (PGS), such as poultry house dusts or welding fume. Potential international usability has been built-in by using the Hazard Statements developed for the Globally Harmonised System (GHS) and providing recommended RPE in picture form as well as with a written specification. Illustration helps to compensate for the variabilities in assigned protection factors across the world. RPE-Select uses easily understandable descriptions/explanations and an interactive stepwise flow for providing input/answers at each step. The output of the selection process is a report summarising the user input data and a selection of RPE, including types of filters where applicable, from which the user can select the appropriate one for each wearer. In addition, each report includes 'Dos' and 'Don'ts' for the recommended RPE. RPE-Select outcomes, based on up to 20 hypothetical use scenarios, were evaluated in comparison with other available RPE selection processes and tools, and by 32 independent users with a broad range of familiarities with industrial use scenarios in general and respiratory protection in particular. For scenarios involving substances having safety data sheets

  7. Theory and experiment of an inertia-type vertical isolation system for seismic protection of equipment

    NASA Astrophysics Data System (ADS)

    Although it has been proven that seismic isolation is an effective technology for seismic protection of structures and equipment, most existing isolation systems are for mitigating horizontal ground motions, and in practice there are very few vertical isolation systems. Part of the reason is due to the conflict with regard to the demand for isolation stiffness. In other words, a vertical isolation system must have sufficient vertical rigidity to sustain the weight of the isolated object, while it must also have sufficient flexibility in order to elongate the vibration period under seismic excitation. In order to overcome this difficulty, a novel system is proposed in this study, called an inertia-type vertical isolation system (IVIS). The primary difference between the IVIS and a traditional system is that the former has an additional leverage mechanism with a counterweight. The counterweight will provide a static uplifting force and an extra dynamic inertia force, such that the effective vertical stiffness of the IVIS becomes higher in its static state and lower in the dynamic one. The theory underlying the IVIS is developed and verified experimentally by a seismic simulation test in this work. The results show that the IVIS leads to a less static settlement and at the same time a lower effective isolation frequency. The test results also demonstrate that the isolator displacement demand of the IVIS is only about 30-40 percent that of the traditional one in all kinds of earthquakes. With regard to the reduction of acceleration response, the IVIS is particularly effective for near-fault earthquakes or near-resonant excitations, but is less effective for far-field earthquakes with more high-frequency contents, as compared with the traditional system.

    Following a chemical, biological, radiation, and nuclear incident, prompt cardiopulmonary resuscitation (CPR) procedure is essential for patients who suffer cardiac arrest. But CPR when wearing personal protection equipment (PPE) before decontamination becomes a challenge for healthcare workers (HCW). Although previous studies have assessed the impact of PPE on airway management, there is little research available regarding the quality of chest compression (CC) when wearing PPE.A present randomized cross-over simulation study was designed to evaluate the effect of PPE on CC performance using mannequins.The study was set in one university medical center in the China.Forty anesthesia residents participated in this randomized cross-over study.Each participant performed 2 min of CC on a manikin with and without PPE, respectively. Participants were randomized into 2 groups that either performed CC with PPE first, followed by a trial without PPE after a 180-min rest, or vice versa.CPR recording technology was used to objectively quantify the quality of CC. Additionally, participants' physiological parameters and subjective fatigue score values were recorded.With the use of PPE, a significant decrease of the percentage of effective compressions (41.3 ± 17.1% with PPE vs 67.5 ± 15.6% without PPE, P < 0.001) and the percentage of adequate compressions (67.7 ± 18.9% with PPE vs 80.7 ± 15.5% without PPE, P < 0.001) were observed. Furthermore, the increases in heart rate, mean arterial pressure, and subjective fatigue score values were more obvious with the use of PPE (all P < 0.01).We found significant deterioration of CC performance in HCW with the use of a level-C PPE, which may be a disadvantage for enhancing survival of cardiac arrest.

    Backround Community-associated methicillin-resistant Staphylococcus aureus outbreaks have occurred in individuals engaged in athletic activities such as wrestling and football. Potential disease reduction interventions include the reduction or elimination of bacteria on common use items such as equipment. Chlorine dioxide has a long history of use as a disinfectant. The purpose of this investigation was to evaluate the ability of novel portable chlorine dioxide generation devices to eliminate bacteria contamination of helmets and pads used by individuals engaged in football. Methods In field studies, the number of bacteria associated with heavily used football helmets and shoulder pads was determined before and after overnight treatment with chlorine dioxide gas. Bacteria were recovered using cotton swabs and plated onto trypticase soy agar plates. In laboratory studies, Staphylococcus aureus was applied directly to pads. The penetration of bacteria into the pads was determined by inoculating agar plates with portions of the pads taken from the different layers of padding. The ability to eliminate bacteria on the pad surface and underlying foam layers after treatment with chlorine dioxide was also determined. Results Rates of recovery of bacteria after treatment clearly demonstrated that chlorine dioxide significantly (p < 0.001) reduce and eliminated bacteria found on the surface of pads. For example, the soft surface of shoulder pads from a university averaged 2.7 × 103 recoverable bacteria colonies before chlorine dioxide treatment and 1.3 × 102 recoverable colonies after treatment. In addition, the gas was capable of penetrating the mesh surface layer and killing bacteria in the underlying foam pad layers. Here, 7 × 103 to 4.5 × 103 laboratory applied S. aureus colonies were recovered from underlying layers before treatment and 0 colonies were present after treatment. Both naturally occurring bacteria and S. aureus were susceptible to the treatment process

    Background A rapid review, guided by a protocol, was conducted to inform development of the World Health Organization’s guideline on personal protective equipment in the context of the ongoing (2013–present) Western African filovirus disease outbreak, with a focus on health care workers directly caring for patients with Ebola or Marburg virus diseases. Methods Electronic databases and grey literature sources were searched. Eligibility criteria initially included comparative studies on Ebola and Marburg virus diseases reported in English or French, but criteria were expanded to studies on other viral hemorrhagic fevers and non-comparative designs due to the paucity of studies. After title and abstract screening (two people to exclude), full-text reports of potentially relevant articles were assessed in duplicate. Fifty-seven percent of extraction information was verified. The Grading of Recommendations Assessment, Development and Evaluation framework was used to inform the quality of evidence assessments. Results Thirty non-comparative studies (8 related to Ebola virus disease) were located, and 27 provided data on viral transmission. Reporting of personal protective equipment components and infection prevention and control protocols was generally poor. Conclusions Insufficient evidence exists to draw conclusions regarding the comparative effectiveness of various types of personal protective equipment. Additional research is urgently needed to determine optimal PPE for health care workers caring for patients with filovirus. PMID:26451847

    The BEPC(Beijing Electron-Positron Collider) is upgraded to be BEPCII, a two-ring Electron-Positron collider. Due to the construction of the BEPCII and upgrade of the existing front ends and beamlines, all the existing EPSs(Equipment Protection Systems) have to be redesigned and reconstructed at BSRF. All the redesigned EPSs for the upgrading front ends and beamlines are a PLC- and SCADA-based equipment protection and control and monitoring system. The EPSs are used to protect BEPCII two storage rings vacuum against vacuum failures in a beamline, as well as to protect the front-end and beamline components from being damaged by synchrotron radiation. For the high-power wiggler beam lines, a fast movable mask is used to protect the blade of a fast-closing valve from damage when the fast-closing valve is triggered to close, which does not need to dump the electron beam running in BEPCII outer ring. In addition, all redesigned PLC- based EPSs are used to communicate with the same centralized monitoring computer to monitor a variety of parameters from all PLC- based EPS systems. The monitoring computer runs the SCADA (Supervisory Control And Data Acquisition) software with its own web server. Graphical HMI interfaces are used to display a few overall views of all front-end equipment operation status and the further detailed information for each EPS in a different pop-up window. On the web services, the SCADA-based centralized monitoring system provides a web browse function, etc. The design of the reconstructed systems is described in this paper.

    The problems of protecting optical and protective glasses are dealt with. The solutions are recommended regarding the contaminant gas cloud of spacecraft, space debris, particles from ERE (electric rocket engines). New solutions are discussed as (i) the use of induced magnetic fields for deflection of charged particles, (ii) shielding from particles by specially generated gas cloud. The results can significantly impact the direction of future research in the field of protection of astronomical and geophysical sites.

  3. Results of tests of Insta-Foam Thermal Protection System (TPS) material for protection of equipment inside the SRB aft skirt

    The objective of these tests was to determine whether Insta-Foam can be used successfully to protect items inside the solid rocket booster aft skirt during reentry. On some of the early Space Shuttle flights the aft skirt heat shield curtain failed during reentry. This allowed the hot gases to damage some of the equipment, etc., inside the skirt. For example, some of the propellant lines were overheated and ruptured and some of the NSI (nozzle severance) cables were damaged. It was suggested that the Insta-Foam thermal protection system be sprayed over these lines, etc., to protect them during future flights in case of a curtain failure. The tests presented were devised and run to check out the feasibility of this idea.

    The use of synthetic pesticides in tropical countries has increased over the years, following the intensification of agriculture. However, awareness among farmers of the importance of protecting themselves from hazards associated with pesticide application is still lacking, especially in Indonesia. This paper reports results of an inventory on knowledge and attitudes regarding pesticide use by melon farmers of a village in Central Java, Indonesia. The importance of using personal protective equipment such as hats, masks, goggles, boots, and gloves on agricultural land is known and well understood by the farmers. However, in practice, only 3.8 % were wearing glasses and 1.9 % were using boots. In fact, the masks used only consisted of a part of their shirt tied around the mouth. The farmers were not wearing long pants and shirts with long sleeves and used the same clothes for more than 1 day without washing. Almost no farmers used personal protective equipment that was standard, in good condition, and complete. Based on the results of statistical analysis, no significant relationship was found between knowledge and attitude on the required practices on the one hand and the use of personal protective equipment in practice on the other hand. This shows that improved knowledge and attitudes are not enough to change the behavior of farmers to work in a healthy and safe way. The gap between knowledge and practice needs to be bridged by a more interactive and participatory training model. It is therefore of paramount importance to develop a special toolkit for pesticide risk reduction which is developed in a participatory manner involving the farmers as the main actors through a series of focus group discussions and field simulations.

  17. Audit Report on "Management Controls over the Department's Excess Weapons Inventories and Selected Sensitive Equipment used by Protective Forces"

    SciTech Connect

    2009-01-01

    Since September 11, 2001, the Department of Energy has, on several occasions, revised its security posture based on identified threats and adversaries. These revisions in security posture have driven Departmental sites to upgrade their defensive and tactical equipment. Subsequent changes in the perceived threats have, in some cases, led to a reduction in the need for certain types of weapons, thus creating a pool of surplus equipment. These surplus weapons could potentially be used by other Department sites and Federal law enforcement agencies. Recent Office of Inspector General reports have raised concerns with the adequacy of controls related to defensive and tactical equipment. For example, our report on Management Controls Over Defense Related High Risk Property (OAS-M-08-06, April 2008) found that administrative controls over certain defense related high risk property were not sufficient for providing accountability over these items. Because of prior reported weaknesses in controls over defensive and tactical equipment, we initiated this audit to determine whether the Department and its contractors were properly managing excess weapons inventories and selected sensitive equipment used by protective forces. Our review disclosed that the Department was not always properly managing its inventories of excess weapons and selected sensitive equipment. We identified issues with the retention of unneeded weapons at many locations and with the identification and tracking of sensitive items. More specifically: Sites maintained large inventories of weapons that were no longer needed but had not been made available for use by either other Departmental sites or other Federal law enforcement agencies. For instance, at six of the locations included in our review we identified a total of 2,635 unneeded weapons with a total acquisition value of over $2.8 million that had not been officially declared as excess - an action that would have made them available for others to use

  18. Special article: personal protective equipment for care of pandemic influenza patients: a training workshop for the powered air purifying respirator.

    2010-10-01

    Virulent respiratory infectious diseases may present a life-threatening risk for health care professionals during aerosol-generating procedures, including endotracheal intubation. The 2009 Pandemic Influenza A (H1N1) brings this concern to the immediate forefront. The Centers for Disease Control and Prevention have stated that, when performing or participating in aerosol-generating procedures on patients with virulent contagious respiratory diseases, health care professionals must wear a minimum of the N95 respirator, and they may wish to consider using the powered air purifying respirator (PAPR). For influenza and other diseases transmitted by both respiratory and contact modes, protective respirators must be combined with contact precautions. The PAPR provides 2.5 to 100 times greater protection than the N95, when used within the context of an Occupational Safety and Health Administration-compliant respiratory protection program. The relative protective capability of a respirator is quantified using the assigned protection factor. The level of protection designated by the APF can only be achieved with appropriate training and correct use of the respirator. Face seal leakage limits the protective capability of the N95 respirator, and fit testing does not assure the ability to maintain a tight face seal. The protective capability of the PAPR will be defeated by improper handling of contaminated equipment, incorrect assembly and maintenance, and improper don (put on) and doff (take off) procedures. Stress, discomfort, and physical encumbrance may impair performance. Acclimatization through training will mitigate these effects. Training in the use of PAPRs in advance of their need is strongly advised. "Just in time" training is unlikely to provide adequate preparation for groups of practitioners requiring specialized personal protective equipment during a pandemic. Employee health departments in hospitals may not presently have a PAPR training program in place

    Despite evident protective value of motorcycle personal protective equipment (PPE), no research has assessed considerations behind its uptake in UK riders. A cross-sectional online questionnaire design was employed, with riders (n=268) recruited from online motorcycle forums. Principal component analysis found four PPE behavioural outcomes. Theoretical factors of intentions, attitudes, injunctive and descriptive subjective norms, risk perceptions, anticipated regret, benefits and habit were also identified for further analysis. High motorcycle jacket, trousers and boots wear, middling high-visibility wear and low non-Personal Protective Equipment wear were found. Greater intentions, anticipated regret and perceived benefits were significantly associated with increased motorcycle jacket, trousers and boots wear, with habit presence and scooter use significantly associated with increased high-visibility wear. Lower intentions, anticipated regret and risk perceptions, being female, not holding a car licence and urban riding were significantly associated with increased non-PPE wear. A need for freedom of choice and mixed attitudes towards PPE use were evident in additional comments. PPE determinants in this sample provide a preliminary basis for future uptake interventions. Larger scale and qualitative research is needed to further investigate relevant constructs. PMID:24076303

  20. The need for empirically derived permeation data for personal protective equipment: the death of Dr. Karen E. Wetterhahn.

    Personal protective equipment (PPE) is an essential component in any occupational health and safety program. The appropriate selection and use of PPE can help prevent or limit exposure to hazardous materials. The inappropriate selection or use of PPE can lead to unnecessary exposure or --with extremely hazardous materials--serious harm including death. In 1997, Dr. Karen E. Wetterhahn died from mercury poisoning resulting from a single exposure to dimethylmercury almost a year before. Her death raised numerous questions as to how this tragedy occurred and what could be done to protect against a chemical as dangerous as dimethylmercury. This article provides a brief review of the case and discusses the glove permeation testing done during the course of the accident investigation. Using this case as an example, the author argues that all recommendations for PPE be based on empirical testing using accepted methods and that this information be readily available. PMID:11217716

    Agriculture consistently ranks among the top hazardous occupations, accounting for a significant number of injuries and fatalities in the workplace. Eastern North Carolina has a significant number of small, independent, family-run, owned, and operated farms. However, little is known about perception, behavior, training, accessibility, or purchasing personal protective equipment (PPE) for safety among farmers in the region. In this study, telephone interviews were conducted among participating farmers between March and June 2012 (N = 129). Univariate and bivariate analyses were conducted to examine associations between PPE behavior and workplace hazards, health-related concerns, and wearing and purchasing PPE. Findings indicated that personal behavior of wearing hearing protection devices (HPDs) and protection from the sun among farmers was low. However, a relatively high percentage of farmers reported wearing PPE when working with agricultural chemicals. Most farmers received training from agricultural extension offices. The findings indicate that, in general, farmers are well aware of the risks associated with occupational hazards and recognize concern for health and safety protection in the workplace. Transitioning these concerns into preventative action remains a challenge and priority for the agricultural health professional. PMID:25635742

    1997-11-01

    Thermal sprayed ethylene methacrylic acid (EMAA) and ethylene tetrafluoroethylene (ETFE), spray-and-bake ETFE and polyvinylidene fluoride (PVDF) and brushable ceramic-epoxy coatings were evaluated for corrosion protection in a biochemical process to treat geothermal residues. The findings are also relevant to other moderate temperature brine environments where corrosion is a problem. Coupon, Atlas cell, peel strength, cathodic disbondment and abrasion tests were performed in aggressive environments including geothermal sludge, hypersaline brine and sulfur-oxidizing bacteria (Thiobadus ferrooxidans) to determine suitability for protecting storage tanks and reaction vessels. It was found that all of the coatings were resistant to chemical attack and biodegradation at the test temperature of 55 C. The EMAA coatings protected 316L stainless steel from corrosion in coupon tests. However, corrosion of mild steel substrates thermal sprayed with EMAA and ETFE occurred in Atlas cell tests that simulated a lined reactor operating environment and this resulted in decreased adhesive strength. Peel tests to measure residual adhesion revealed that failure mode was dependent on exposure conditions. Long-term tests on the durability of ceramic-epoxy coatings in brine and bacteria are ongoing. Initial indications are that this coating has suitable characteristics. Abrasion tests showed that the ceramic-epoxy had good resistance to the abrasive effects of sludge. Thermal sprayed EMAA coatings also displayed abrasion resistance. Cathodic disbondment tests in brine at room temperature indicated that EMAA coatings are resistant to disbondment at applied potentials of {minus}780 to {minus}1,070 mV SCE for the test conditions and duration. Slight disbondment of one specimen occurred at a potential of {minus}1,500 mV SCE. The EMAA may be suited to use in conjunction with cathodic protection although further long-term, higher temperature testing would be needed.

    1991-04-01

    Records of the Navy Safety Center, Norfolk, VA were reviewed to find data relevant to inadvertant operation of installed fire extinguishing systems in civilian nuclear power plants. Navy data show the incidence of collateral fire or other damage by fresh water on operating electrical equipment in submarines and in shore facilities is about the same as the civilian experience, about 30 percent. Aboard surface ships, however, the collateral damage incidence in much lower, about 15 percent. With sea water, the collateral damage incidence is at least 75 percent. It is concluded that the fire extinguisher water has to be contaminated, as by rust in sprinkler systems or deposited salt spray, for most collateral damage to occur. Reasons for inadvertant operation (or advertant operation) of firex systems at shore facilities, submarines, and surface ships resemble those for nuclear power plants. Mechanical or electrical failures lead the list, followed by mishaps during maintenance. Detector and alarm system failures are significant problems at Navy shore facilities, and significant at nuclear power plants. Fixed halon and CO2 systems in shore facilities cause no collateral damage. Lists of individual Navy incidents with water and with halon and carbon dioxide are included as appendices.

    Background The incidence of sport-related concussion (SRC) in high school football is well documented. However, limited prospective data are available regarding how player characteristics and protective equipment affect the incidence of SRC. Purpose To determine whether the type of protective equipment (helmet and mouth guard) and player characteristics affect the incidence of SRC in high school football players. Design Cohort study; Level of evidence, 2. Methods Certified athletic trainers (ATs) at each high school recorded the type of helmet worn (brand, model, purchase year, and recondition status) by each player as well as information regarding players’ demographics, type of mouth guard used, and history of SRC. The ATs also recorded the incidence and days lost from participation for each SRC. Incidence of SRC was compared for various helmets, type of mouth guard, history of SRC, and player demographics. Results A total of 2081 players (grades 9–12) enrolled during the 2012 and/or 2013 football seasons (2287 player-seasons) and participated in 134,437 football (practice or competition) exposures. Of these players, 206 (9%) sustained a total of 211 SRCs (1.56/1000 exposures). There was no difference in the incidence of SRC (number of helmets, % SRC [95% CI]) for players wearing Riddell (1171, 9.1% [7.6%–11.0%]), Schutt (680, 8.7% [6.7%–11.1%]), or Xenith (436, 9.2% [6.7%–12.4%]) helmets. Helmet age and recondition status did not affect the incidence of SRC. The rate of SRC (hazard ratio [HR]) was higher in players who wore a custom mouth guard (HR = 1.69 [95% CI, 1.20–2.37], P <.001) than in players who wore a generic mouth guard. The rate of SRC was also higher (HR = 1.96 [95% CI, 1.40–2.73], P <.001) in players who had sustained an SRC within the previous 12 months (15.1% of the 259 players [95% CI, 11.0%–20.1%]) than in players without a previous SRC (8.2% of the 2028 players [95% CI, 7.1%–9.5%]). Conclusion Incidence of SRC was similar

    Despite decades of ongoing improvement, astronauts must still struggle with inhibited dexterity and accelerated fatigue due to the requirement of wearing a pressurized Extra-Vehicular Activity (EVA) glove. Recent research in the Anthropometry and Biomechanics Facility at NASA's Johnson Space Center has focused on developing requirements for improvements in the design of the next generation of EVA glove. In the course of this research, it was decided to expand the scope of the testing to include a variety of commercially available athletic and consumer gloves to help provide a more recognizable comparison for investigators and designers to evaluate the current state of EVA glove mobility and strength. This comparison is being provided with the hope that innovative methods may help commercial development of gloves for various athletic and personal protective endeavors.

    The subject of the theory of vibrations has carried an aesthetic appeal to generations of engineering students for its richness of ideas, and for the intellectual challenges it offers. Also, the diverse range of its applications (covering civil, mechanical, automotive, and aerospace structures) has provided obvious motivations for its study. For most students, the subject provides, perhaps, the first encounter in substantial application of mathematical tools (differential equations, calculus of variations, Fourier/Laplace transforms, and matrix algebra) to engineering problems. The intimate relationship that the subject of mechanics has with mathematics strikes home probably for the first time. While teaching this subject, the instructor is spoilt for choice in selecting a text book and so are the students who wish to pursue a self-study of the subject. Many luminaries in the field have offered their own exposition of the subject: starting from the classics of Rayleigh, Timoshenko, Den Hartog, Bishop and Johnson, and the works of more recent vintage (e.g., the books by Meirovich, Clough, and Penzien, and works with computational flavour, such as, those by Bathe and Petyt), several works easily come to one's mind. Given this milieu, it requires a distinctive conviction to write a new book on this subject. And, here we have a book, written by a practitioner, which aims to deal with fundamental aspects of vibrations of engineering systems. The scepticism that this reviewer had on the need for having one more such book vanished as he browsed through the book and read selectively a few sections. The author's gift for elegant explanations is immediately noticeable even in such a preliminary reading. After a more careful reading, the reviewer has found this book to be insightful and he considers the book to be a welcome addition to the family of books on vibration engineering. The author has struck a fine balance between physical explanations, mathematical niceties

    An incident involving chemical warfare agents requires a unique hazardous materials (HAZMAT) response. As with an HAZMAT event, federal regulations prescribe that responders must be protected from exposure to the chemical agents. But unlike other HAZMAT events, special considerations govern selection of personal protective equipment (PPE). PPE includes all clothing, respirators and monitoring devices used to respond to a chemical release. PPE can differ depending on whether responders are military or civilian personnel.

    Monte Carlo calculations were used to investigate the efficiency of radiation protection equipment in reducing eye and whole body doses during fluoroscopically guided interventional procedures. Eye lens doses were determined considering different models of eyewear with various shapes, sizes and lead thickness. The origin of scattered radiation reaching the eyes was also assessed to explain the variation in the protection efficiency of the different eyewear models with exposure conditions. The work also investigates the variation of eye and whole body doses with ceiling-suspended shields of various shapes and positioning. For all simulations, a broad spectrum of configurations typical for most interventional procedures was considered. Calculations showed that 'wrap around' glasses are the most efficient eyewear models reducing, on average, the dose by 74% and 21% for the left and right eyes respectively. The air gap between the glasses and the eyes was found to be the primary source of scattered radiation reaching the eyes. The ceiling-suspended screens were more efficient when positioned close to the patient's skin and to the x-ray field. With the use of such shields, the Hp(10) values recorded at the collar, chest and waist level and the Hp(3) values for both eyes were reduced on average by 47%, 37%, 20% and 56% respectively. Finally, simulations proved that beam quality and lead thickness have little influence on eye dose while beam projection, the position and head orientation of the operator as well as the distance between the image detector and the patient are key parameters affecting eye and whole body doses.

    The purpose of this study was to investigate smart features required for the next generation of personal protective equipment (PPE) for firefighters in Australia, Korea, Japan, and the USA. Questionnaire responses were obtained from 167 Australian, 351 Japanese, 413 Korean, and 763 U.S. firefighters (1,611 males and 61 females). Preferences concerning smart features varied among countries, with 27% of Korean and 30% of U.S. firefighters identifying ‘a location monitoring system’ as the most important element. On the other hand, 43% of Japanese firefighters preferred ‘an automatic body cooling system’ while 21% of the Australian firefighters selected equally ‘an automatic body cooling system’ and ‘a wireless communication system’. When asked to rank these elements in descending priority, responses across these countries were very similar with the following items ranked highest: ‘a location monitoring system’, ‘an automatic body cooling system’, ‘a wireless communication system’, and ‘a vision support system’. The least preferred elements were ‘an automatic body warming system’ and ‘a voice recording system’. No preferential relationship was apparent for age, work experience, gender or anthropometric characteristics. These results have implications for the development of the next generation of PPE along with the international standardisation of the smart PPE. PMID:26027710

    Tuberculosis infection is prevalent in Korea and health care workers are vulnerable to tuberculosis infection in the hospital. The aims of this study were to develop and validate an education program that teaches senior medical students how to wear and choose the proper size and type of respiratory protective equipment (RPE), which may help reduce the risk of contracting Mycobacterium tuberculosis (MTB) from patients. Overall, 50 senior medical students participated in this education program. Methods of choosing the proper type of RPE, performing a fit check of the RPE, and choosing a suitable mask size were taught by certified instructors using the real-time quantitative fit test (QNFT). The validity of education program was evaluated with qualitative fit test (QLFT) before and after the education as pass or fail. The education program was effective, as shown by the significantly pass rate (increased 30 to 74%) in the QLFT after the education program (p<0.05). Among study participants, changing mask size from medium to small significantly increased the pass rate (p<0.001). Incorporation of this program into the medical school curriculum may help reduce risk of MTB infection in medical students working in the hospital. PMID:26538001

    Use of personal protective equipment (PPE) and safety medical devices is mandated for healthcare workers to reduce the risk of infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) from exposure to patients' blood. Research has shown that a strong safety climate may promote increased use of PPE. Therefore, the objective of this study was to examine the association between safety climate and use of PPE among homecare/hospice nurses in North Carolina. To this end, a mail survey was conducted in 2006. The response rate, adjusted on the assumption that the proportion of eligible nurses from among those who did not return the questionnaire or could not be contacted was similar to the proportion among those who did return the questionnaire, was 69% (n=833 eligibles). The percentage of nurses who used the specified PPE was two to three times greater among nurses who had a strong safety climate. Safety climate was only weakly associated with using safety devices. These results suggest that improving safety climate may be a powerful tool for increasing use of PPE. PMID:25055845

    The high exposure risks of workers to herbicides in low- and middle-income countries is an important public health concern because of the potential resulting negative impacts on workers' health. This study investigated workers' personal protective equipment (PPE) compliance as a risk mitigation measure; particularly workers who apply herbicides for Working for Water (WfW) - a South African invasive alien vegetation control programme. The study aim was to understand workers' low PPE compliance by analysing their risk perceptions of herbicide use, working conditions and socio-cultural context. Research methods included ethnographic observations, informal interviews, visual media, questionnaires and a focus group. Study results indicated that low PPE compliance persists despite workers' awareness of herbicide exposure risks and as a result of the influence from workers' socio-cultural context (i.e. gender dynamics and social status), herbicide risk perceptions and working conditions (i.e. environmental and logistical). Interestingly, teams comprised of mostly women had the highest compliance rate. These findings highlighted that given the complexity of PPE compliance, especially in countries with several economic and social constraints, exposure reduction interventions should not rely solely on PPE use promotion. Instead, other control strategies requiring less worker input for effectiveness should be implemented, such as elimination and substitution of highly hazardous pesticides, and altering application methods.

    Six different supraglottic airway devices: Combitube™, laryngeal mask airway, intubating laryngeal mask airway (Fastrach™), i-gel™, Laryngeal Tube™ and Pro-Seal™ laryngeal mask airway were assessed by 58 paramedic students for speed and ease of insertion in a manikin, whilst wearing either chemical, biological, radiation, nuclear-personal protective equipment (CBRN-PPE) or a standard uniform. All devices took significantly longer to insert when wearing CBRN-PPE compared with standard uniform (p < 0.001). In standard uniform, insertion time was shorter than 45 s in 90% of attempts for all devices except the Combitube, for which 90% of attempts were completed by 53 s. Whilst wearing CBRN-PPE the i-gel was the fastest device to insert with a mean (SD (95% CI)) insertion time of 19 (8 (17-21))s, p < 0.001, with the Combitube the slowest with mean (65 (23 (59-71))s. Wearing of CBRN-PPE has a negative impact on supraglottic airway insertion time. PMID:21883122

    The aim of this study was to investigate stable and valid measurement sites of skin temperatures as a non-invasive variable to predict deep-body temperature while wearing firefighters' personal protective equipment (PPE) during air temperature changes. Eight male firefighters participated in an experiment which consisted of 60-min exercise and 10-min recovery while wearing PPE without self-contained breathing apparatus (7.75 kg in total PPE mass). Air temperature was periodically fluctuated from 29.5 to 35.5 °C with an amplitude of 6 °C. Rectal temperature was chosen as a deep-body temperature, and 12 skin temperatures were recorded. The results showed that the forehead and chest were identified as the most valid sites to predict rectal temperature (R(2) = 0.826 and 0.824, respectively) in an environment with periodically fluctuated air temperatures. This study suggests that particular skin temperatures are valid as a non-invasive variable when predicting rectal temperature of an individual wearing PPE in changing ambient temperatures. Practitioner Summary: This study should offer assistance for developing a more reliable indirect indicating system of individual heat strain for firefighters in real time, which can be used practically as a precaution of firefighters' heat-related illness and utilised along with physiological monitoring.

Methods of choosing the proper type of RPE, performing a fit check of the RPE, and choosing a suitable mask size were taught by certified instructors using the real-time quantitative fit test (QNFT). The validity of education program was evaluated with qualitative fit test (QLFT) before and after the education as pass or fail. The education program was effective, as shown by the significantly pass rate (increased 30 to 74%) in the QLFT after the education program (p<0.05). Among study participants, changing mask size from medium to small significantly increased the pass rate (p<0.001). Incorporation of this program into the medical school curriculum may help reduce risk of MTB infection in medical students working in the hospital. PMID:26538001

    For many years a good introductory book for undergraduate and postgraduate students on remote sensing of the Earth's land surface, which was not starting with an emphasis on traditional photographic techniques, was missing. In 2010 the first edition of the book Fundamentals of Satellite Remote Sensing by Emilio Chuvieco and Alfredo Huete was published by CRC Press and it was filling this gap. Now the second edition by Emilio Chuvieco was published by CRC Press. This second edition is made more attractive by the use of colour and including colour illustrations instead of the black-and-white ones in the first edition.

  9. Development of a draft British standard: the assessment of heat strain for workers wearing personal protective equipment.

    PubMed

    Hanson, M A

    1999-07-01

    Existing methods for estimating heat stress, enshrined in British/International Standards (the Wet Bulb Globe Temperature (WBGT) index [BS EN 27243] and the Required Sweat Rate equation [BS EN 12515; ISO 7933 modified]), assume that the clothing worn by the individual is water vapour permeable; the WBGT index also assumes that the clothing is relatively light. Because most forms of personal protective equipment (PPE) either have a higher insulative value than that assumed or are water vapour impermeable, the Standards cannot be accurately applied to workers wearing PPE. There was, therefore, a need to develop a British Standard which would allow interpretation of these existing Standards for workers wearing PPE. Relevant information was obtained through reviewing the literature and consulting experts. Two questionnaire surveys of potential users of the Standards were conducted, and physiological data collected both experimentally and in work situations were considered. The information collected was used to develop the draft British Standard. It provides information and data on: The general effect of PPE on heat balance of the body (the ability of the body to maintain its 'core' temperature within an acceptable range). The effect of specific forms of PPE on metabolic heat production rate. The thermal insulation and evaporative resistance of types of PPE. The effect of the closure of the garments to the body on heat transfer. The effect of the PPE on the proportion of the body covered. The effect of an air supply (for example, Breathing Apparatus [BA]) to the wearer. Guidance is given on conducting an analysis of the work situation, taking account of the impact of PPE. Detailed methods of interpreting both BS EN 27243 and BS EN 12515 for workers wearing PPE are given, taking account of the factors listed above. Three worked examples using BS EN 27243 and BS EN 12515 are given in the Annex of the draft Standard. PMID:10481630

    The use of geospatial data for a wide variety of applications has increased continuously over the last decades and a great variety of packages of open source GIS software are now available, with diverse characteristics. R was created as free software mainly for statistical computation and graphics, but offers now a large diversity of packages to process and visualize spatial data. Many books dedicated to R are available (e.g., Zuur et al., 2009; Chambers, 2008), but not many about spatial analysis in R (Bivand et al., 2008). The book under analysis is aimed for beginners both in R and in spatial analysis, and therefore can be used as a starting point for students and professionals which may want to enter the area of spatial analysis with R.

    Compiling a good book on urban remote sensing is probably as hard as the research in this disciplinary field itself. Urban areas comprise various environments and show high heterogeneity in many respects, they are highly dynamic in time and space and at the same time of greatest influence on connected and even tele-connected regions due to their great economic importance. Urban remote sensing is therefore of great importance, yet as manifold as its study area: mapping urban areas (or sub-categories thereof) plays an important (and challenging) role in land use and land cover (change) monitoring; the analysis of urban green and forests is by itself a specialization of ecological remote sensing; urban climatology asks for spatially and temporally highly resolved remote sensing products; the detection of artificial objects is not only a common and important remote sensing application but also a typical benchmark for image analysis techniques, etc. Urban analyses are performed with all available spaceborne sensor types and at the same time they are one of the most relevant fields for airborne remote sensing. Several books on urban remote sensing have been published during the past 10 years, each taking a different perspective. The book Global Urban Monitoring and Assessment through Earth Observation is motivated by the objectives of the Global Urban Observation and Information Task (SB-04) in the GEOSS (Global Earth Observation System of Systems) 2012-2015 workplan (compare Chapter 2) and wants to highlight the global aspects of state-of-the-art urban remote sensing.

    Writing a biography of a complex personality and mastermind like Albert Einstein is a daunting task for any historian of science. Yet the sheer temptation of writing his biography has apparently helped to overcome scholarly scruples, as biographies of Einstein have appeared quite regularly on the market. One of them is Einstein: his Life and Universe by journalist Walter Isaacson. It is a best-seller, which is one of the reasons the book deserves a critical evaluation. Isaacson is a man of considerable repute: he has been the chairman of CNN and managing editor of Time magazine. Isaacson's Einstein is written in a style that is accessible to a wide audience. Scholars who are already familiar with Einstein's physics may still enjoy the parts of the book that deal with the relation between Einstein and the press. Indeed, the breadth of its scope is the book's major merit, as it connects the personal, scientific, public and political dimensions of Einstein's life. In this review, I discuss Isaacson's treatment of these dimensions one-by-one.

    While "hydrostatics" has been known since antiquity, the word "hydrodynamics" was only coined by Daniel Bernoulli in 1738. From about that time onward the mechanics of fluids became an important area of physics which attracted the interest of some of the greatest mathematical physicists, including Euler, d'Alembert, Lagrange and Cauchy. Yet, in spite of its undeniable importance in the history of science, hydrodynamics has been largely ignored by modern historians. Fortunately this situation has now changed with the publication of Olivier Darrigol's book, which offers a modern and thorough treatment of the subject from its beginning about 1740 to the 1920s. It is to be hoped that the book will stimulate further interest in the history of hydrodynamics and related areas such as the history of elasticity and aerodynamics, and continuum mechanics in general. Darrigol, who may be best known for his works in the history of quantum and relativity theories, published in 2000 a comprehensive survey of the development of electrodynamics from Ampère to Einstein, a much needed replacement of Edmund Whittaker's classical history of ether and electricity. His present work gives a concise yet wide-ranging synthetic account of the development of hydrodynamics, an area of physics with some historical connections to field electrodynamics.

    Mauro Dorato's new book is subtitled "An Introduction to the History and Philosophy of Laws of Nature". This is a bit misleading: a reader previously unacquainted with any of the literature on the topic of laws of nature and related problems in the philosophy of science will find much of the book prohibitively challenging. But the book does aim for the kind of breadth and generality that one would expect from an introduction to the subject, and it serves well as a compact overview of the issues, views, arguments, and counter-arguments that have shaped the contemporary philosophical debate on laws of nature. Almost no important facet of the debate goes untouched. There are chapters or sections on: recent scholarship on the history of the notion of a law and its role in the study of nature; the characteristics of the things called "laws" in a wide range of sciences; the relations among laws, algorithmic compressibility of information, and the theory of measurement; the puzzling question of why so many laws of nature should be mathematical in form; regularity theories of laws; the universals approach to laws; the necessitarian approach to laws; skeptical eliminativism about laws; non-reductive realism about laws; the question of the supervenience of laws on non-nomic facts; the relations of laws to counterfactuals, causality, dispositions, explanation, chance, symmetry, and necessity; ceteris paribus clauses; the evolutionary contingency thesis and the question of biological laws; Wilhelm Dilthey and the alleged distinction between "nomothetic" sciences and "historical" ones; the question of psychophysical laws and the relation between this question and the problems of mental causation and free will; even the connection between the issue of psychophysical laws and Gibson's ecological theory of perception.

    The Bureau of Mines, U.S. Department of the Interior, is reviewing explosion protection methods for use in gassy coal mines. This performance criteria guideline is an evaluation of three explosion protection methods of machines electrically powered with voltages up to 15,000 volts ac. A sufficient amount of basic research has been accomplished to verify that the explosion proof and pressurized enclosure methods can provide adequate explosion protection with the present state of the art up to 15,000 volts ac. This routine application of the potted enclosure as a stand alone protection method requires further investigation or development in order to clarify performance criteria and verification certification requirements. An extensive literature search, a series of high voltage tests, and a design evaluation of the three explosion protection methods indicate that the explosion proof, pressurized, and potted enclosures can all be used to enclose up to 15,000 volts ac.

    This book concerns the many lives of Hugh Everett's seminal work on the interpretation of quantum mechanics. As these many lives were spread over time, like layers, the reading of this book is like an archeological tour as well as an adventure in physics, its philosophy and history. In short, the story traces the lives of his work. The first life was around 1956-1957 when Everett, a doctoral student under John Archibald Wheeler, wrote his dissertation at Princeton University and published it in the journal Review of Modern Physics. He presented an interpretation which dispensed with the need to collapse quantum states during measurements, thus dissolving the quantum measurement problem, and consistently reproduced results from quantum mechanics using Schrödinger's equation alone. Despite the face value of such a proposal it drew little attention until the end of the 1960s. This was when the second life of Everett's work began. In 1967 Bryce DeWitt appealed to Everett's work while working on the quantization of general relativity creating what is now called the Wheeler-DeWitt equation. Furthermore, DeWitt wanted give to Everett's work a wider audience than experts in quantum gravity. Supported by the editors of Physics Today a paper by himself presenting this interpretation as one of the possible ones for quantum mechanics triggered a heated debate on the subject in the periodical. Together with this new life a layer beneath the original publication of the dissertation appeared. In contact with Everett, DeWitt discovered that the 1957 dissertation and paper had been an abridged version of a more consistently developed interpretation. The full version of the work was then published in 1973 with the enticing title, suggested by DeWitt, of "The Many-Worlds Interpretation of Quantum Mechanics." This second life was larger than the first one, indeed it is alive until today, sparking a huge amount of technical work by physicists and philosophers attempting to solve what

    The overlap of early Ebola virus disease (EVD) symptoms (eg, fever, headache, abdominal pain, diarrhea, emesis, and fatigue) with symptoms of other more common travel-related diseases (eg, malaria, typhoid fever, pneumonia, and meningococcemia) may result in delayed diagnosis of EVD before isolation of infected patients. Radiology departments should consider policies for and approaches to decontamination of expensive and potentially easily damaged radiology equipment. In addition, the protection of radiology personnel must be considered during the work-up phase of undiagnosed EVD patients presenting to emergency departments. The purpose of this article is to consider the effect of EVD on radiology departments and imaging equipment, with particular consideration of guidelines currently available from the Centers for Disease Control and Prevention that may be applicable to radiology. © RSNA, 2015 PMID:25654616

  10. Justification for Selecting Level A vs. Level B Personal Protective Equipment to Remediate a Room Containing Concentrated Acids, Bases and Radiological Constituents

    Selecting the appropriate personal protective equipment (PPE) is based on providing an adequate level of employee protection relative to the task-specific conditions and hazards. PPE is categorized into four ensembles, based on the degree of protection afforded; e.g., Levels A (most restrictive), B, C, and D (least restrictive). What is often overlooked in preparing an ensemble is that the PPE itself can create significant worker hazards; i.e., the greater the level of PPE, the greater the associated risks. Furthermore, there is confusion as to whether a more ''conservative approach'' should always be taken since Level B provides the same level of respiratory protection as Level A but less skin protection. This paper summarizes the Occupational Safety and Health Administration regulations addressing Level A versus Level B, and provides justification for selecting Level B over Level A without under-protecting the employee during a particular remediation scenario. The scenario consisted of an entry team performing (1) an initial entry into a room containing concentrated acids (e.g., hydrofluoric acid), bases, and radiological constituents; (2) sampling and characterizing container contents; and (3) retrieving characterized containers. The invasive nature of the hydrofluoric acid sampling and characterization scenario created a high potential for splash, immersion, and exposure to hazardous vapors, requiring additional skin protection. The hazards associated with this scenario and the chemical nature of hydrofluoric acid provided qualitative evidence to justify Level A. Once the hydrofluoric acid was removed from the room, PPE performance was evaluated against the remaining chemical inventory. If chemical breakthrough from direct contact was not expected to occur and instrument readings confirmed the absence of any hazardous vapors, additional skin protection afforded by wearing a vapor-tight, totally-encapsulated suit was not required. Therefore, PPE performance and

    Objective In order to assess potential contributors to high injury rates and smoking prevalence among construction workers, we investigated the association of safety climate with personal protective equipment (PPE) use, and smoking behaviors. Methods Logistic regression models estimated risk ratios for PPE use and smoking using data from participants in MassBUILT smoking cessation intervention (n=1,725). Results Contractor safety climate was negatively associated with use of dust masks (RR=0.88,95%CI:0.83–0.94); respirators (RR=0.82,95%CI:0.75–0.89); general equipment (RR=0.98,95%CI:0.95–1.00); and fall protection (RR=0.94,95%CI:0.91–0.98) and positively associated with current smoking (RR=1.12,95%CI:1.01–1.25) but not smoking cessation. Coworker safety climate was negatively associated with use of dust masks (RR=0.87,95%CI:0.82–0.92); respirators (RR=0.80,95%CI:0.74–0.87); general equipment (RR=0.96,95%CI:0.94–0.98); fall (RR=0.92,95%CI:0.89–0.96) and hearing (RR=0.88,95%CI:0.83–0.93) protection but not smoking. Conclusions Worksite safety climate may be important for PPE use and smoking, but further research is needed. PMID:25285831

    For the last 10 years, the Partnership for Citrus Workers Health (PCWH) has been an evidence-based intervention program that promotes the adoption of protective eye safety equipment among Spanish-speaking farmworkers of Florida. At the root of this program is the systematic use of community-based preventive marketing (CBPM) and the training of community health workers (CHWs) among citrus harvester using popular education. CBPM is a model that combines the organizational system of community-based participatory research (CBPR) and the strategies of social marketing. This particular program relied on formative research data using a mixed-methods approach and a multilevel stakeholder analysis that allowed for rapid dissemination, effective increase of personal protective equipment (PPE) usage, and a subsequent impact on adoptive workers and companies. Focus groups, face-to-face interviews, surveys, participant observation, Greco-Latin square, and quasi-experimental tests were implemented. A 20-hour popular education training produced CHWs that translated results of the formative research to potential adopters and also provided first aid skills for eye injuries. Reduction of injuries is not limited to the use of safety glasses, but also to the adoption of timely intervention and regular eye hygiene. Limitations include adoption in only large companies, rapid decline of eye safety glasses without consistent intervention, technological limitations of glasses, and thorough cost-benefit analysis.

    The results of tests of plasma treatment of zirconium and deposition of protective yttrium coatings used as the methods of protection of zirconium components of light water reactor cores against hydrogenation are detailed. The amount of hydrogen in the treated sample exposed to superheated steam for 2500 h at temperature T = 400°C and pressure p = 1 atm was five times lower than the corresponding value for the untreated one. The amount of hydrogen in the sample coated with yttrium remained almost unchanged in 4000 h of exposure. A plasma method for rapid testing for hydrogen resistance is proposed. The hydrogenation rate provided by this method is 700 times higher than that in tests with superheated steam. The results of preliminary experiments confirm the possibility of constructing a unit for batch processing of the surfaces of fuel rod claddings.

    This paper discusses the impact behavior of a self-healing ionomeric polymer and compares its protection capability against space debris impacts to that of simple aluminium-alloy bumpers. To this end, 14 impact experiments on both ionomer and Al-7075-T6 thin plates with similar surface density were made with 1.5 mm aluminium spheres at velocity between 1 and 4 km/s.First, the perforation extent in both materials was evaluated vis-à-vis the prediction of well known hole-size equations; then, attention was given to the damage potential of the cloud of fragments ejected from the rear side of the target by analysing the craters pattern and the momentum transferred to witness plates mounted on a ballistic pendulum behind the bumpers.Self-healing was completely successful in all but one ionomer samples and the primary damage on ionomeric polymers was found to be significantly lower than that on aluminium. On the other hand, aluminium plates exhibited slightly better debris fragmentation abilities, even though the protecting performance of ionomers seemed to improve at increasing impact speed.

    PURPOSE: This book provides step-by-step guidance on developing a sound publication strategy for how to prepare and get research papers published. The book is a user-friendly guide, a route map for publishing that covers many topics, ranging from abstracts and blogs, tables and trial registration to ethical principles and conventions for writing scientific papers. Publishing the results of scientific research in the form of a scientific paper is the ultimate goal and the final stage of the research of each scientist. To write and publish papers is never going to be an easy task. With this book as their guide, researchers will be better informed and therefore should have an easier and altogether more pleasant path to publication with clear direction on how to choose the right journal, avoid publication delays, and resolve authorship disputes and many other problems associated with scientific publishing. CONTENTS: The 188 pages of the book are distributed in 5 chapters in Part I and 249 entries ordered by the letters of Alphabet in Part II creating an A to Z of publication strategy. In the Appendices there are four sections covering further reading, organizations, guidelines and principles of good publication practice for company-sponsored medical research. The book also contains key references and useful websites within many entries where it seemed helpful. The last ten pages of the book present an index to help users to find the information of interest in the book. CONCLUSION: The book is intended to help all authors, young and old, novice and experienced, to plan their research and publications effectively and prepare manuscripts for journals and other publications, increasing the likelihood that their work will be published. Providing essential information on publishing strategy and process, the book should be extremely useful to everyone who wants to publish research results.

    The study of braneworlds has been an area of intense activity over the past decade, with thousands of papers being written, and many important technical advances being made. This book focuses on a particular aspect of braneworlds, namely perturbative gravity in one specific model: the Randall-Sundrum model. The book starts with an overview of the Randall-Sundrum model, discussing anti-de Sitter (AdS) space and the Israel equations in some detail. It then moves on to discuss cosmological branes, focusing on branes with constant curvature. The book then turns to brane gravity, i.e. what do we, as brane observers, perceive the gravitational interaction to be on the brane as derived from the actual five-dimensional gravitational physics? After a derivation of the general brane equations from the Israel equations, the remainder of the book deals with perturbative gravity. This part of the book is extremely detailed, with calculations given explicitly. Overall, the book is quite pedagogical in style, with the aim being to explain in detail the topics it chooses to cover. While it is not unusual to have books written on current and extremely popular research areas, it is unusual to have calculations written so explicitly. This is both a strength and a weakness of this book. It is a strength because the calculations are presented in a detail that students learning the topic will definitely appreciate; however, the narrow focus of the book also means that it lacks perspective and fails to present the broader context. In choosing to focus on one particular aspect of Randall-Sundrum branes, the book has not managed to communicate why a large number of theorists have worked so intensively on this model. In its early stages, the explicit detail of the Randall-Sundrum model would be extremely useful for a student starting out in this research area. In addition, the calculational detail later in the computation of the graviton propagator on the brane would also be welcome not

    Physics 1 is an attractive book designed to cover the whole of the AS physics course and has been endorsed by OCR for its Advanced AS and A2 specifications. Built on books from the Cambridge Modular Sciences series, it provides a clearly presented path through each of the three sections: Foundation Physics, Electrons and Photons, and Wave Properties. Each chapter has clearly stated objectives and is peppered with self-assessment questions, the answers to all of which are at the back of the book. Additional questions are given at the end of each chapter. There is an excellent use of colour, summary boxes and diagrams, but relatively few photographs. At the back of the book is a useful section on uncertainties and a glossary. The key feature of this book is its accessibility to students coming from a double-award science background. A great deal of thought has gone into lessening the trauma of the transition to Advanced Level and the results are impressive. Some of the main areas of concern for many students are the mathematical sections. These areas are not rushed, especially in the foundation physics, where there are plenty of worked examples. It is assumed, also, that students will not necessarily be confident with graphs so lots of examples are given. Diagrams of the type of practical equipment students are likely to encounter add another dimension to the book. It is good to see the use of light gates and motion sensors in addition to the more traditional ticker-timers for the calculations of speed and acceleration. Accessibility is the strength of this book. The use of colour and space, as well as the content, make it enjoyable to use and to read for any student embarking on the new AS courses. Helen Reynolds

    Books produced since 1850, held in the Library of Congress, have a very high acid content, hence a shorter life expectancy than prior-published volumes. A means of "deacidifying" books on a large, economically-viable scale is of great interest, particularly to the research library community, which stores millions of valuable, often irreplaceable documents. The General Electric vacuum chamber used in deacidification tests serves a dual purpose. It creates an environment in which DEZ can do its job without presence of oxygen and also dries the books. After the drying phase, DEZ is introduced to the chamber as a paper-penetrating vapor. The complete process typically takes eight days, four days for vacuum drying and four days of book exposure to DEZ. Accelerated aging tests showed that the process can extend paper life almost fourfold, even on color illustrations.

    The extent of thermal strain while wearing personal protective equipment (PPE) during care activities for Ebola virus disease patients has not yet been characterized. From January to March 2015, 25 French healthcare workers (HCWs) in Conakry, Guinea, volunteered to be monitored while wearing PPE using an ingestible thermal sensor. The mean (standard deviation) working ambient temperature and relative humidity were 29.6 °C (2.0 °C) and 65.4% (10.3%), respectively; the mean time wearing PPE was 65.7 (13.5) minutes; and the mean core body temperature increased by 0.46 °C (0.20 °C). Four HCWs reached or exceeded a mean core body temperature of ≥ 38.5 °C. HCWs wearing PPE for approximately 1 hour exhibited moderate but safe thermal strain. PMID:26655297

    Students with special health care needs (SHCNs) and individualized education plans (IEPs) may be injured more often in vocational, career, and technical education (CTE) programs. No research to date considers personal protective equipment (PPE) use among students with SHCNs in school-based programs reporting injuries to agencies. Data from 1999 to 2011 on PPE use among injured students in CTE programs in public schools and private secondary schools for the disabled were analyzed; students with SHCNs were distinguished by IEP status within New Jersey Safe Schools surveilance data. Among students with IEPs using PPE, 36% of injuries occurred to body parts PPE was meant to protect. Likely injury types were cuts-lacerations and burns for students with IEPs using PPE and cuts-lacerations and sprains for students with IEPs not using PPE. Females with IEPs using PPE were injured less often than males across ages. Results suggested students with SHCNs with IEPs need further job-related training with increased emphasis on properly selecting and fitting PPE. PMID:24571050

    In recent years, there has been a growing resurgence of interest in the philosophical views of the founders of quantum mechanics. Kristian Camilleri's book on Werner Heisenberg's philosophy of quantum mechanics is a welcome addition to this literature. It takes Heisenberg seriously as a philosopher of science, traces the various philosophical influences on his view, and carefully distinguishes his interpretation of quantum mechanics from that of his contemporaries. It is a fine example of the new insights that can emerge when one takes an integrated approach to the history and philosophy of science. After summarizing some of the main themes of the book, I will turn to two moderate criticisms of the book-one stylistic, and the other, regarding its content.

    The second edition of Mathematical Methods for Physics and Engineering by Riley et al is a great scientific textbook. The reader should not be intimidated by its size - over 1200 pages - and skimming through it, one is confronted with a vast amount of information (which could be daunting for students). However, when reading it in detail one realizes that the number of pages is justified and the result is a self-contained reference on mathematical methods for physics. The book is well organized: it starts at basic university undergraduate level and progresses to the highest graduate level. It is a tour de force to write mathematical sections that are both complete and at a appropriate academic level; the sequence of sections (and their content) has been chosen with great care in order that each section may introduce the following ones. The authors have clearly succeeded with this challenge, making this a remarkable pedagogical book. No precise knowledge is needed at the beginning, and all the material is presented in a logical progression. The student can confidently follow the material as it is presented. Even though this book is devoted to physics and engineering, it can be used by students in other scientific fields. The material covered in the book concentrates on applied theorems and formulae. But as the title of the book indicates, it is primarily written 'for physics and engineering' so this is to be expected and it greatly simplifies the text of the course. Consequently, derivations of the main results are essentially 'for physicists'. Frequently proofs are briefly outlined and are not as detailed as many mathematicians would like. Nevertheless, the final results are always clearly stated together with the technical conditions under which they should be used, thus providing a very comprehensive and practical textbook. The only criticism is that the sections on probability and statistics do not fit comfortably between their previous and following sections

    This book represents the proceedings of the five day programme on IMRT techniques presented at the 2003 American Association of Physicists in Medicine (AAPM) Summer School held in Colorado Springs, Colorado. The book is essentially an overview of IMRT techniques, discussing the history, the mathematical processes involved in the planning stages, the biological indices for evaluations, the off-line and on-line medical imaging that is required, the various IMRT delivery techniques available, positioning and motion verification, shielding and QA issues, and some clinical applications. There is some additional discussion on modulated electron and proton therapy, views on the clinical and financial impact of IMRT, as well as some speculation on the future uses of IMRT. The fact that the book is an `overview' must be emphasized. Medical physicists who are well-read in IMRT, or have implemented IMRT, even partially, may be a little disappointed with the book. Although specific details were purposely omitted, the well-read physicist would have preferred to go right to the `heart of the matter', something this book fails to do. As is typical of many proceedings-type books, there is a certain level of inconsistency of writing styles, as well as some redundancy between the different chapters. It is unfortunate that such a large volume does not have an index to allow a reader to explore a particular subject pertaining to IMRT. The reader would have to guide himself/herself by the table of contents before each chapter which could be a problem if the reader requires some information quickly. It is interesting to note that the book lends itself to a variety of professionals interested in IMRT, including administrators. It may be a source of help for medical physicists who wish to discuss IMRT issues with higher level administration, for example. Some clinical applications are also reviewed. The lack of details concerning the advantages of IMRT with respect to clinical outcome is

I believe the authors are correct in stating that the book is unique in specifically covering electrodynamic phenomena associated with magnetic fields, though of course some of the more elementary aspects are covered in the classical textbooks on electromagnetism, which are duly acknowledged. This interdisciplinarity makes the book very interesting to people with a range of backgrounds. For example, as a plasma physicist, I was familiar with most of the material on plasmas, but liquid crystals and superconductors were entirely new territory for me. These chapters were indeed both accessible and interesting, and it was surprising for me to see how much commonality there is in the physics of these various media. The first part of the book covers some fundamentals of electrodynamics and magnetostatics, and of electromagnetic waves. Most of this material is covered in textbooks on electromagnetism, and some of it is very basic (for example, LRC circuit theory, surely covered in most first year physics courses, is included) but it is perhaps a useful prelude for what is to come. The generic topic of charged particle motion in electromagnetic fields is well covered. Three main magnetoactive media are then discussed: plasmas (focusing on waves), liquid crystals and superconductors. It is all too easy to criticise a book on the grounds of omitted material, but I do feel that a chapter on magnetostatics in plasmas would have been very helpful, covering force-free fields and so on. Some interesting analogies could then have been exploited. For example, I was intrigued to discover an equation for magnetic fields in superconductors (equation (9.36)) which, apart from a change of sign, is identical to the Helmholtz equation used to\

    This study evaluated the physiological tolerance times when wearing explosive and chemical (>35 kg) personal protective equipment (PPE) in simulated environmental extremes across a range of differing work intensities. Twelve healthy males undertook nine trials which involved walking on a treadmill at 2.5, 4, and 5.5 km·h−1 in the following environmental conditions, 21, 30, and 37°C wet bulb globe temperature (WBGT). Participants exercised for 60 min or until volitional fatigue, core temperature reached 39°C, or heart rate exceeded 90% of maximum. Tolerance time, core temperature, skin temperature, mean body temperature, heart rate, and body mass loss were measured. Exercise time was reduced in the higher WBGT environments (WBGT37 < WBGT30 < WBGT21; P < 0.05) and work intensities (5.5 < 4 < 2.5 km·h−1; P < 0.001). The majority of trials (85/108; 78.7%) were terminated due to participant's heart rate exceeding 90% of their maximum. A total of eight trials (7.4%) lasted the full duration. Only nine (8.3%) trials were terminated due to volitional fatigue and six (5.6%) due to core temperatures in excess of 39°C. These results demonstrate that physiological tolerance times are influenced by the external environment and workload and that cardiovascular strain is the limiting factor to work tolerance when wearing this heavy multilayered PPE.

    Most of us sometimes have to face a student asking: 'What do I need to get started on this'. (In my case 'this' would typically be a topic in general relativity.) After thinking about it for quite a while, and consulting candidate texts again and again, a few days later I usually end up saying: read this chapter in book I (but without going too much detail), then that chapter in book II (but ignore all those comments), then the first few sections of this review paper (but do not try to work out equations NN to NNN), and then come back to see me. In the unlikely event that the student comes back without changing the topic, there follows quite a bit of explaining on a blackboard over the following weeks. From now on I will say: get acquainted with the material covered by this book. As far as Isham's book is concerned, 'this' in the student's question above can stand for any topic in theoretical physics which touches upon differential geometry (and I can only think of very few which do not). Said plainly: this book contains most of the introductory material necessary to get started in general relativity, or those branches of mathematical physics which require differential geometry. A student who has mastered the notions presented in the book will have a solid basis to continue into specialized topics. I am not aware of any other book which would be as useful as this one in terms of the spectrum of topics covered, stopping at the right place to get sufficient introductory insight. According to the publisher, these lecture notes are the content of an introductory course on differential geometry which is taken by first-year theoretical physics PhD students, or by students attending the one-year MSc course 'Quantum Fields and Fundamental Forces' at Imperial College, London. The volume is divided into six chapters: An Introduction to Topology Differential Manifolds Vector Fields and n-Forms Lie Groups Fibre Bundles Connections in a Bundle.

    This book is a comprehensive and innovative text which provides a timely overview of the state of the art on surface metrology. Besides the presentation of surface texture and roundness measurements, surface microscopy and tribology, the focus is on quality and calibration techniques, uncertainty and traceability of measurements. A detailed description of surface parameters and calibration artefacts is given with reference to the current written standards. The volume examines classical and new methodologies in use in academia and in industry. Instruments and techniques operating from the micrometre range down to the nanometre range are well described. Numerous photographs, illustrations and sketches provide a clear understanding of instruments and techniques applied in surface metrology. The text gives scientific details, applications and future perspectives in this field, including good explanations of concepts and terms of metrology. Uncertainty, traceability, reference artefacts and techniques for roundness and surface texture measurements are well discussed in this book.

    Thanks to its impressive success in the second half of the 20th century, both in high-energy physics and in critical phenomena, quantum field theory has enjoyed an abundant literature. We therefore greet yet another book on this subject with caution: what can a monograph on quantum field theory bring now that is new, either conceptually or pedagogically? But when it is written by a physicist such as Bryce DeWitt, who has made his own contribution to the collection of field theory books with The Global Approach to Quantum Field Theory, all suspicion is naturally abandoned. One knows in advance that this book can only lead to a genuine enrichment of the literature. DeWitt has made a formidable contribution to various areas of physics: general relativity, the interpretation of quantum mechanics, and most of all the quantization of non-Abelian gauge theories and quantum gravity. In addition, his pedagogical publications, especially the Les Houches schools of 1963 and 1983 [1, 2], have had a great impact on quantum field theory. All this makes the reader keen to pick up his new work and a deeper reading confirms the reviewer's initial enthusiasm. We must begin by alerting the potential readers of this book that it cannot be compared to any other book in the field (unless of course we are talking about references [1] and [2], of which the book under review is an extension and reworking). This uniqueness applies to both the scientific content and the way the ideas are presented. A quick description of this book and a brief explanation of its title should convince the reader of the book's unique quality. For DeWitt, a central concept of field theory is that of `space of histories'. For a field varphii defined on a given spacetime M, the set of all varphii(x) for all x in all charts of M defines its history. It is the space Phi of all possible histories (dynamically allowed or not) of the fields defined on M which is called the `space of histories' by DeWitt. If only

    I have had a love/hate relationship with this book ever since it first came out. On the one hand, this is an excellent introduction for mathematicians to the differential geometry underlying general relativity. On the other hand, this is definitely a book for mathematicians. The book's greatest strength is its clear, precise presentation of the basic ideas in differential geometry, combined with equally clear and precise applications to theoretical physics, notably general relativity. But the book's precision is also its greatest weakness; this is not an easy book to read for non-mathematicians, who may not appreciate the notational complexity, some of which is nonstandard. The present edition is very similar to the original, published in 1992. In addition to minor revisions and clarifications of the material, there is now a brief introduction to fibre bundles, and a (very) brief discussion of the gauge theory description of fundamental particles. The index to the symbols used is also a more complete than in the past, but without the descriptive material present in the previous edition. The bulk of the book consists of a careful introduction to tensors and their properties. Tensors are introduced first as linear maps on vector spaces, and only later generalized to tensor fields on manifolds. The differentiation and integration of differential forms is discussed in detail, including Stokes' theorem, Lie differentiation and Hodge duality, and connections, curvature and torsion. To this point, Wasserman's text can be viewed as an expanded version of Bishop and Goldberg's classic text [1], one major difference being Wasserman's inclusion of the pseudo-Riemannian case from the beginning (in particular, when discussing Hodge duality). Whether one prefers Wasserman's approach to Bishop and Goldberg's is largely a matter of taste: Wasserman's treatment is both more complete and more precise, making it easier to check calculations in detail, but occasionally more difficult

    A book of this nature is long overdue; as could be expected from the pedigree of the editors, the coverage is comprehensive and, thanks to the authors selected, is of high quality. The book is divided into five sections, the central three of which are concerned with the measurement techniques themselves. The invasive techniques of mechanical testing and bone histology are dealt with in great detail at a level suitable for postgraduate students looking for an introduction to these techniques at a practical level. In the section dealing with the measurement techniques which use ionizing radiation, the chapters on DXA, neutron activation and radiogrammetry are well detailed and again at the appropriate level for postgraduate students. However, the chapters dealing with quantitative CT techniques are missing the sort of information that would have given them more authority. There is no mention of reconstruction algorithms or some of the typical shortcomings (e.g. partial volume artefacts) of these techniques and, given the excellent quality of the rest of the book, this was disappointing. The third of these technique sections deals with methods that do not use ionizing radiation. As one might expect with these two editors, the chapter on ultrasound is excellent and the coverage thorough and deep. The chapter on MRI and bone is particularly useful and timely as little has been published in this area and the debate about how best to measure bone quality in vivo has recently been rejoined. The chapters on finite element modelling and vibration analysis give a useful overview of the topics and have comprehensive reference lists for anyone who wishes to deepen their studies. The book has a useful introductory section. Bone biology is discussed in some detail, providing sufficient knowledge for the reader to be able to understand the basis and significance of the measurement techniques that follow. Exhaustive coverage is given to biological and radiation safety issues which

    This is a very interesting collection of introductory and review articles on the theory and applications of classical and quantum integrable systems. The book reviews several integrable systems such as the KdV equation, vertex models, RSOS and IRF models, spin chains, integrable differential equations, discrete systems, Ising, Potts and other lattice models and reaction--diffusion processes, as well as outlining major methods of solving integrable systems. These include Lax pairs, Bäcklund and Miura transformations, the inverse scattering method, various types of the Bethe Ansatz, Painlevé methods, the dbar method and fusion methods to mention just a few. The book is divided into two parts, each containing five chapters. The first part is devoted to classical integrable systems and introduces the subject through the KdV equation, and then proceeds through Painlevé analysis, discrete systems and two-dimensional integrable partial differential equations, to culminate in the review of solvable lattice models in statistical physics, solved through the coordinate and algebraic Bethe Ansatz methods. The second part deals with quantum integrable systems, and begins with an outline of unifying approaches to quantum, statistical, ultralocal and non-ultralocal systems. The theory and methods of solving quantum integrable spin chains are then described. Recent developments in applying Bethe Ansatz methods in condensed matter physics, including superconductivity and nanoscale physics, are reviewed. The book concludes with an introduction to diffusion--reaction processes. Every chapter is devoted to a different subject and is self-contained, and thus can be read separately. A reader interesting in classical methods of solitons, such as the methods of solving the KdV equation, can start from Chapter 1, while a reader interested in the Bethe Ansatz method can immediately proceed to Chapter 5, and so on. Thus the book should appeal and be useful to a wide range of theoretical

    Quantum Noise is advertised as a handbook, and this is indeed how it functions for me these days: it is a book that I keep within hand's reach, ready to be consulted on the proper use of quantum stochastic methods in the course of my research on quantum dots. I should point out that quantum optics, the target field for this book, is not my field by training. So I have much to learn, and find this handbook to be a reliable and helpful guide. Crispin Gardiner previously wrote the Handbook of Stochastic Methods (also published by Springer), which provides an overview of methods in classical statistical physics. Quantum Noise, written jointly with Peter Zoller, is the counterpart for quantum statistical physics, and indeed the two books rely on each other by frequent cross referencing. The fundamental problem addressed by Quantum Noise is how the quantum dynamics of an open system can be described statistically by treating the environment as a source of noise. This is a general problem in condensed matter physics (in particular in the context of Josephson junctions) and in quantum optics. The emphasis in this book in on the optical applications (for condensed matter applications one could consult Quantum Dissipative Systems by Ulrich Weiss, published by World Scientific). The optical applications centre around the interaction of light with atoms, where the atoms represent the open system and the light is the noisy environment. A complete description of the production and detection of non-classical states of radiation (such as squeezed states) can be obtained using one of the equivalent quantum stochastic formulations: the quantum Langevin equation for the field operators (in either the Ito or the Stratonovich form), the Master equation for the density matrix, or the stochastic Schrödinger equation for the wave functions. Each formulation is fully developed here (as one would expect from a handbook), with detailed instructions on how to go from one to the other. The

    Networks have been recently recognized as playing a central role in understanding a wide range of systems spanning diverse scientific domains such as physics and biology, economics, computer science and information technology. Specific examples run from the structure of the Internet and the World Wide Web to the interconnections of finance agents and ecological food webs. These networked systems are generally made by many components whose microscopic interactions give rise to global structures characterized by emergent collective behaviour and complex topological properties. In this context the statistical physics approach finds a natural application since it attempts to explain the various large-scale statistical properties of networks in terms of local interactions governing the dynamical evolution of the constituent elements of the system. It is not by chance then that many of the seminal papers in the field have been published in the physics literature, and have nevertheless made a considerable impact on other disciplines. Indeed, a truly interdisciplinary approach is required in order to understand each specific system of interest, leading to a very interesting cross-fertilization between different scientific areas defining the emergence of a new research field sometimes called network science. The book of Dorogovtsev and Mendes is the first comprehensive monograph on this new scientific field. It provides a thorough presentation of the forefront research activities in the area of complex networks, with an extensive sampling of the disciplines involved and the kinds of problems that form the subject of inquiry. The book starts with a short introduction to graphs and network theory that introduces the tools and mathematical background needed for the rest of the book.

    General relativity is one of the cornerstones of modern physics. In spite of this, the teaching of general relativity at undergraduate level remains quite marginal. The reasons for this particular situation are quite well known. We can quote, for example, two of them: general relativity requires specific mathematical tools that are somehow outside the mainstream of undergraduate technical development; moreover, this is a branch of physics whose observational and experimental applications have remained rare until recent times, and even though this scenario has changed dramatically in the last few years, the new situation has not yet been absorbed into undergraduate teaching. However, there are many textbooks devoted to the teaching of general relativity at undergraduate level. The recent book of J B Hartle, Gravity: An Introduction to Einstein's General Relativity, is a new proposal in this sense. It is perhaps one of the most interesting pedagogical approaches seeking to surmount the difficulties that arise when one tries to include general relativity in undergraduate teaching. In this new book, Hartle attempts to address the difficuties that must be faced by anyone who teaches general relativity at undergraduate level. In order to not scare the student with the hard technical preparation needed to obtain the basic equations of general relativity, Einstein's equations, he simply gives up the idea of introducing these equations at the very beginning. Instead, he chooses to present Einstein's equations, with most of the mathematics needed to do them, in the last part of the book. This delicate (and of course dangerous) choice has the advantage of introducing the reader first to the physical aspects of general relativity. This approach can be dangerous because the relevant solutions of the equations necessary to discuss the physical content of general relativiy are presented first without a formal derivation. But the author circumvents this potential drawback in a

    Background Farmworkers’ exposures to pesticides are reduced when they wear personal protective equipment (PPE), and mobile health (mHealth) platforms can potentially deliver information to farmworkers to help promote PPE use. However, little is known about the feasibility of using mHealth platforms to promote farmworkers’ use of PPE. Objective The objective of the study was to describe the development and feasibility-testing of Protect Yourself! (¡Protéjase!), an intervention designed to increase PPE use. As the vast majority of farmworkers in the United States are from Mexico, we examined the intervention in a primarily Mexican-origin farmworker population. Methods ¡Protéjase was developed in several steps. First, we performed ethnographic observations to understand what prevents PPE use. Next, we developed program components that met the challenges uncovered in the ethnographic observations, seeking direct feedback from farmworkers on each component. Feasibility was assessed using surveys and focus groups. Material was provided in Spanish or English at the preference of the participant. Finally, we pilot tested each component of the intervention, including: (1) PPE that was provided to each worker for their personal use during the intervention trial, and (2) delivery of an application-based tool that promoted the use of PPE through daily individualized messaging. Results 55 farmworkers enrolled in the study, but only 41 of 55 (75%) completed the entire pilot intervention trial. Results focus on the evaluation of the intervention, and include only those who completed the entire trial. Among farmworkers who completed the entire intervention trial, all but two farmworkers were born in Mexico and were Spanish speaking. Still, all study participants self-identified as Mexican or Mexican-American. When asked what changes were needed in the intervention’s messaging or delivery to increase user satisfaction, 22 out of 41 participants (54%) felt that no changes

    'The Black Hole at the Center of the Milky Way' collects and presents recent advances in galactic centre research in a unified form by some of the researches at the forefront of the field. This book presents an opportunity to review the observational evidence for the best constrained black hole candidate currently known. In my opinion, the authors succeed in producing a good topical reference, appropriate for advanced students and working researchers, providing and excellent summary of the state of near-infrared results in particular. While the title refers exclusively to the supermassive black hole associated with the compact radio source Sagittarius A*, the text has a broader focus, discussing the nuclear region of the galaxy. Indeed, this is necessary given that most of the restrictions upon the characteristics of the central supermassive black hole have been obtained indirectly via stellar observations in it's vicinity. This also has the virtue of introducing a number of interesting additional astrophysical mysteries associated with the galactic centre (e.g. the so-called 'paradox of youth', referring to the presence of excessively young stars). The first section of the book contains a primer on the astronomical techniques applied to the galactic Centre. As with the rest of the text, the discussion of near-infrared techniques dominates, providing only a short summary of radio interferometry, and optical through gamma-ray techniques. While this primer is a useful introduction for the working researcher, or advanced student, it is not exhaustive and thus presumes at least a passing familiarity with the methods discussed. The second and third sections are devoted to a summary of observations and their astrophysical interpretation, respectively. Necessarily there is considerable overlap between these and they may have benefited from being combined. Nevertheless, each subsection is relatively self-contained which, when combined with the numerous data and graphs

    This new book on quantum field theory by Michele Maggiore fits well into the Oxford Master Series in Physics, which is designed for final year undergraduate and beginning graduate students in physics. It is based on the teaching experience of the author with students in the fourth year at the University of Geneva. In this sense it is a two-semester course book for students exposed to quantum field theory for the first time. Maggiore gives, on slightly less than 300 pages, a balanced introduction to a vast field of twentieth century physics that will help students going on to study more advanced and specialized courses. Beside applications to many processes in particle physics that can also be found in many other textbooks, the author emphasizes conceptual, structural and methodological aspects of quantum field theory. After an introductory chapter, the group theoretical tools required to implement Lorentz invariance in quantum field theory are developed on 30 pages. Chapter 3 is devoted to classical field theory, emphasizing symmetries and conservation laws. The quantization of free fields in the next chapter follows traditional lines. Here one may miss a section describing the mathematical structure of the Fock space. It is also not said that in infinite dimensions von Neumann's uniqueness theorem for the representations of the canonical commutation relations no longer holds. The operations C, P, T are carefully discussed. In the relatively long chapter 5, perturbation theory and renormalization are developed. In this context the author discusses the modern view on renormalizability, and also emphasizes in a separate section the seriousness of the cosmological constant problem in quantum field theory. The next three chapters provide applications of the theory, especially to quantum electrodynamics and the low-energy limit of the electroweak theory. Chapters 9, 10, and 11 are meant as a bridge to more advanced courses. In these, path integral quantization, non

    Bastianelli and van Nieuwenhuizen's monograph `Path Integrals and Anomalies in Curved Space' collects in one volume the results of the authors' 15-year research programme on anomalies that arise in Feynman diagrams of quantum field theories on curved manifolds. The programme was spurred by the path-integral techniques introduced in Alvarez-Gaumé and Witten's renowned 1983 paper on gravitational anomalies which, together with the anomaly cancellation paper by Green and Schwarz, led to the string theory explosion of the 1980s. The authors have produced a tour de force, giving a comprehensive and pedagogical exposition of material that is central to current research. The first part of the book develops from scratch a formalism for defining and evaluating quantum mechanical path integrals in nonlinear sigma models, using time slicing regularization, mode regularization and dimensional regularization. The second part applies this formalism to quantum fields of spin 0, 1/2, 1 and 3/2 and to self-dual antisymmetric tensor fields. The book concludes with a discussion of gravitational anomalies in 10-dimensional supergravities, for both classical and exceptional gauge groups. The target audience is researchers and graduate students in curved spacetime quantum field theory and string theory, and the aims, style and pedagogical level have been chosen with this audience in mind. Path integrals are treated as calculational tools, and the notation and terminology are throughout tailored to calculational convenience, rather than to mathematical rigour. The style is closer to that of an exceedingly thorough and self-contained review article than to that of a textbook. As the authors mention, the first part of the book can be used as an introduction to path integrals in quantum mechanics, although in a classroom setting perhaps more likely as supplementary reading than a primary class text. Readers outside the core audience, including this reviewer, will gain from the book a

    Background. We determined the feasibility of using computer vision and depth sensing to detect healthcare worker (HCW)-patient contacts to estimate both hand hygiene (HH) opportunities and personal protective equipment (PPE) adherence. Methods. We used multiple Microsoft Kinects to track the 3-dimensional movement of HCWs and their hands within hospital rooms. We applied computer vision techniques to recognize and determine the position of fiducial markers attached to the patient's bed to determine the location of the HCW's hands with respect to the bed. To measure our system's ability to detect HCW-patient contacts, we counted each time a HCW's hands entered a virtual rectangular box aligned with a patient bed. To measure PPE adherence, we identified the hands, torso, and face of each HCW on room entry, determined the color of each body area, and compared it with the color of gloves, gowns, and face masks. We independently examined a ground truth video recording and compared it with our system's results. Results. Overall, for touch detection, the sensitivity was 99.7%, with a positive predictive value of 98.7%. For gowned entrances, sensitivity was 100.0% and specificity was 98.15%. For masked entrances, sensitivity was 100.0% and specificity was 98.75%; for gloved entrances, the sensitivity was 86.21% and specificity was 98.28%. Conclusions. Using computer vision and depth sensing, we can estimate potential HH opportunities at the bedside and also estimate adherence to PPE. Our fine-grained estimates of how and how often HCWs interact directly with patients can inform a wide range of patient-safety research. PMID:26949712

    The U.S. Department of Energy (DOE) Oak Ridge Office of Environmental Management (EM-OR) requested that Oak Ridge Associated Universities (ORAU), working under the Oak Ridge Institute for Science and Education (ORISE) contract, provide technical and independent waste management planning support under the American Recovery and Reinvestment Act (ARRA). Specifically, DOE EM-OR requested that ORAU plan and implement a sampling and analysis campaign targeting certain URS|CH2M Oak Ridge, LLC (UCOR) surveillance and maintenance (S&M) process inventory waste. Eight populations of historical and reoccurring S&M waste at the Oak Ridge National Laboratory (ORNL) have been identified in the Waste Handling Plan for Surveillance and Maintenance Activities at the Oak Ridge National Laboratory, DOE/OR/01-2565&D2 (WHP) (DOE 2012) for evaluation and processing to determine a final pathway for disposal. Population 7 (POP 7) consists of 56 containers of aged, low-level and potentially mixed S&M waste that has been staged in various locations around ORNL. Several of these POP 7 containers primarily contain personal protective equipment (PPE) and dry active waste (DAW), but may contain other miscellaneous debris. This data sharing report addresses the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) specified waste in a 13-container subpopulation (including eight steel boxes, three 55-gal drums, one sealand, and one intermodal) that lacked sufficient characterization data for possible disposal at the Environmental Management Waste Management Facility (EMWMF) using the approved Waste Lot (WL) 108.1 profile.

    Amorphous Silicon Solar Cells by K. Takahashi and M. Konagai is one of the first books dealing exclusively with the subject of amorphous silicon solar cells. The book was first published in Japanese in 1983 and was translated and published in English in 1986. Part 1, covering 94 pages, is a general introduction to solar energy, including the basic concepts, the prospects for cost reduction of the various competing photovoltaic technologies, and a discussion of several types of solar power systems, while Part 2 deals exclusively with the technical issues surrounding the application of amorphous silicon to solar cells. Throughout, reference is made to the impact of photovoltaics on the Japanese economy, both as a business activity and as a domestic supply of electrical energy. As the authors point out, photovoltaics is a national priority for the Japanese, with increasing business as well as government support. Although this was also once the case in the U.S., as memories of the recent energy crises fade, the bulk of this activity is shifting toward the Far East.

    Ever since the days of William Blake there has been an underground resistance against the soulless yet triumphant science and its unholy alliance with money, technology and political power. With the nearly undisputed hegemony that science and technological innovation has attained in the post-World War II era, this kind of resistance has resulted in numerous books and articles that in different ways warn against the dark sides of science and the socio-economic system that nourishes a science in degeneration. Classical examples include Herbert Marcuse's One-Dimensional Man (1964), Jacques Ellul's The Technological Society (1965), Theodore Roszak's The Making of a Counter Culture (1968), and Paul Feyerabend's Science in a Free Society (1978). A fair part of the literature written by sociologists and philosophers is not only critical to trends in modern science, but tends to or is overtly anti-science. The book under review belongs in some respects to this heterogeneous literary tradition, but Twilight of the Scientific Age is primarily directed against the institutional system of science and its associated ideology and not against science itself. Indeed, the author is himself a practicing scientist, an astrophysicist, and he emphasizes several times that he firmly believes in science, even that he loves it. He is not a "stupid cultural relativist," he asserts (p. 11), but a critical freethinker independent of dogmatic beliefs.

    The Polish physicist Józio (Joseph, Josh, Jo) Rotblat was catapulted into the public eye when he (and the 'Pugwash Conferences' organization) received the 1995 Nobel Peace Prize. His life prior to that had been most distinguished but conducted well out of the public eye. Born and raised as a Jewish physicist in pre-World War II Poland, and thus potentially educationally disadvantaged, he battled away for education and scientific achievement. He came to Liverpool University just before the outbreak of World War II, worked in James Chadwick's laboratory on the early beginnings of neutron fission physics, moved to Los Alamos to take part in the US-UK collaborative Manhattan Project to build a nuclear bomb and was motivated by a desire to rid Poland of Nazi 'racial cleansing'. On realizing the US-UK goal was somewhat wider, he resigned this work and dedicated his life to the peaceful uses of radiation and the campaigns to rid the world of the potential world-eliminating possibility of nuclear war. For this purpose he interacted with Albert Einstein and Bertrand Russell, and in July 1957 founded the 'Pugwash Conferences', named for a small fishing village in Nova Scotia, Canada where the first was held. Along the way his personal life was no less dramatic. Cruel events conspired, and his wife Tola remained in Poland and was killed in the Nazi extermination camp at Majdanek. He grieved for his beloved Poland and those left behind or unaccounted for. He was suspected by some Americans of being a spy and had his personal papers and family artefacts impounded. After the war he was Professor of Medical Physics at St Bartholomew's Hospital, London for 30 years up to retirement. After John Roberts, he was the second editor of this journal Physics in Medicine and Biology from 1961-72 (see e.g. Bob Burns' paper in our 50th birthday issue, 2006.

    It is not usual for someone to write a book on someone else's Ph.D. thesis, but then Feynman was not a usual physicist. He was without doubt one of the most original physicists of the twentieth century, who has strongly influenced the developments in quantum field theory through his many ingenious contributions. Path integral approach to quantum theories is one such contribution which pervades almost all areas of physics. What is astonishing is that he developed this idea as a graduate student for his Ph.D. thesis which has been printed, for the first time, in the present book along with two other related articles. The early developments in quantum theory, by Heisenberg and Schrödinger, were based on the Hamiltonian formulation, where one starts with the Hamiltonian description of a classical system and then promotes the classical observables to noncommuting quantum operators. However, Dirac had already stressed in an article in 1932 (this article is also reproduced in the present book) that the Lagrangian is more fundamental than the Hamiltonian, at least from the point of view of relativistic invariance and he wondered how the Lagrangian may enter into the quantum description. He had developed this idea through his 'transformation matrix' theory and had even hinted on how the action of the classical theory may enter such a description. However, although the brief paper by Dirac contained the basic essential ideas, it did not fully develop the idea of a Lagrangian description in detail in the functional language. Feynman, on the other hand, was interested in the electromagnetic interactions of the electron from a completely different point of view rooted in a theory involving action-at-a-distance. His theory (along with John Wheeler) did not have a Hamiltonian description and, in order to quantize such a theory, he needed an alternative formulation of quantum mechanics. When the article by Dirac was brought to his attention, he immediately realized what he was

    The motion of a charged particle interacting with its own electromagnetic field is an area of research that has a long history; this problem has never ceased to fascinate its investigators. On the one hand the theory ought to be straightforward to formulate: one has Maxwell's equations that tell the field how to behave (given the motion of the particle), and one has the Lorentz-force law that tells the particle how to move (given the field). On the other hand the theory is fundamentally ambiguous because of the field singularities that necessarily come with a point particle. While each separate sub-problem can easily be solved, to couple the field to the particle in a self-consistent treatment turns out to be tricky. I believe it is this dilemma (the theory is straightforward but tricky) that has been the main source of the endless fascination. For readers of Classical and Quantum Gravity, the fascination does not end there. For them it is also rooted in the fact that the electromagnetic self-force problem is deeply analogous to the gravitational self-force problem, which is of direct relevance to future gravitational wave observations. The motion of point particles in curved spacetime has been the topic of a recent Topical Review [1], and it was the focus of a recent Special Issue [2]. It is surprising to me that radiation reaction is a subject that continues to be poorly covered in the standard textbooks, including Jackson's bible [3]. Exceptions are Rohrlich's excellent text [4], which makes a very useful introduction to radiation reaction, and the Landau and Lifshitz classic [5], which contains what is probably the most perfect summary of the foundational ideas (presented in characteristic terseness). It is therefore with some trepidation that I received Herbert Spohn's book, which covers both the classical and quantum theories of a charged particle coupled to its own field (the presentation is limited to flat spacetime). Is this the text that graduate students

    The ever growing relevance of general relativity to astrophysics and cosmology continues to motivate the publication of new textbooks which put the theory in a fresh perspective informed by recent developments. In the last few years we have witnessed the appearance of two new books which reflect this trend, and which stand proud among the classic relativity texts. While the 1970s were the decade of Weinberg [1] and Misner et al [2], and the 80s the decade of Schutz [3] and Wald [4], this is clearly the decade of Hartle [5] and Carroll. Hartle has introduced a novel pedagogical approach to teaching general relativity, which he convincingly argues [6] should be done in the standard undergraduate physics curriculum. His 'physics-first approach' emphasizes physical phenomena and minimizes mathematical formalism. Hartle achieves a lot by introducing only the spacetime metric and the geodesic equation, which are the main tools needed to explore curved spacetime and extract physical consequences. To be sure, to explain how the metric is obtained in the first place does require a background of differential geometry and the formulation of the Einstein field equations. But in Hartle's book this material is wisely presented at a later stage, after an ample sampling of the physics of curved spacetime has motivated the need for the advanced mathematics. Carroll follows instead the traditional route, what Hartle calls the 'math-first approach', in which one introduces first the required mathematical formalism and only then derives the physical consequences. He is, of course, in good company, as this is the method followed in all existing textbooks (with Hartle's being the sole exception). Carroll's approach may not be original, but it is tried and true, and the result of Carroll's efforts is an excellent introduction to general relativity. The book covers the standard topics that would be found in virtually all textbooks (differential geometry, the field equations, linearized

    This book achieves what its subtitle indicates. The author skilfully weaves together the story of Bragg's life and of the scientific developments with which he was most closely involved. The author has a good understanding of Bragg's scientific work which he explains in considerable detail, with a number of diagrams reproduced from Bragg's papers, and manages to convey the excitement generated by Bragg's discoveries. The salient points of Bragg's life are well known. He was born and brought up in Australia and is still the youngest ever winner of a Nobel prize (though Josephson did his seminal work at a comparable age, it took many years for him to get his Prize). From 1914 to 1918 Bragg was involved with acoustic methods of detecting enemy guns. From 1919 to 1938 he was Professor of Physics in Manchester, and for about a year he was Director of the National Physical Laboratory. He then went to Cambridge as Cavendish Professor until 1953, when he moved to the Royal Institution (where his father had been). While an undergraduate at Cambridge 'Bragg's most influential teacher was...C T R Wilson [Nobel Laureate, 1927]...[whose] lectures "were the best, and delivery the worst, of any lectures to which I have ever been. He mumbled facing the board, he was very hesitant in his delivery, and yet the way he presented the subject was quite brilliant'' '. One wonders how long Wilson's inspirational teaching would survive today, with continual inspections and the requirement to satisfy the demands of the jobsworths. Bragg's comments on this would make interesting reading! Bragg was a very successful public lecturer on science. He made use of vivid analogies, many of which are quoted by Hunter. Since this book is published by Oxford University Press, I hope that some of them may appear in future editions of The Oxford Dictionary of Quotations. (Bragg is included in Mackay's A Dictionary of Scientific Quotations (Bristol: Institute of Physics Publishing)). There are too many

    The most difficult unsolved problem in fundamental theoretical physics is the consistent implementation of the gravitational interaction into a quantum framework, which would lead to a theory of quantum gravity. Although a final answer is still pending, several promising attempts do exist. Despite the general title, this book is about one of them - loop quantum gravity. This approach proceeds from the idea that a direct quantization of Einstein's theory of general relativity is possible. In contrast to string theory, it presupposes that the unification of all interactions is not needed as a prerequisite for quantum gravity. Usually one divides theories of quantum general relativity into covariant and canonical approaches. Covariant theories employ four-dimensional concepts in its formulation, one example being the path integral approach. Canonical theories start from a classical Hamiltonian version of the theory in which spacetime is foliated into spacelike hypersurfaces. Loop quantum gravity is a variant of the canonical approach, the oldest being quantum geometrodynamics where the fundamental configuration variable is the three-metric. Loop quantum gravity has developed from a new choice of canonical variables introduced by Abhay Ashtekar in 1986, the new configuration variable being a connection defined on a three-manifold. Instead of the connection itself, the loop approach employs a non-local version in which the connection is integrated over closed loops. This is similar to the Wilson loops used in gauge theories. Carlo Rovelli is one of the pioneers of loop quantum gravity which he started to develop with Lee Smolin in two papers written in 1988 and 1990. In his book, he presents a comprehensive and competent overview of this approach and provides at the same time the necessary technical background in order to make the treatment self-contained. In fact, half of the book is devoted to 'preparations' giving a detailed account of Hamiltonian mechanics, quantum

    This book is a find. Mariño meets the challenge of filling in less than 200 pages the need for an accessible review of topological gauge / gravity duality. He is one of the pioneers of the subject and a clear expositor. It is no surprise that reading this book is a great pleasure. The existence of dualities between gauge theories and theories of gravity remains one of the most surprising recent discoveries in mathematical physics. While it is probably fair to say that we do not yet understand the full reach of such a relation, the impressive amount of evidence that has accumulated over the past years can be regarded as a substitute for a proof, and will certainly help to delineate the question of what is the most fundamental quantum mechanical theory. As has been the case in the past, it is in the context of Witten's 'topological' quantum theories that the mathematical framework is well enough established to firmly ground, and fully benefit from, the development of the physical theories. This book makes an important contribution to this new chapter in the math / physics interaction. There are two main instances of topological gauge/gravity duality. In the A-model, Chern Simons gauge theory on the 3-sphere is related to the closed topological string theory on the local Calabi Yau 3-fold {\\mathcal O}_{{\\mathbb P}^1}(-1) \\oplus{\\mathcal O}_{{\\mathbb P}^1} (-1), also known as the resolved conifold (Gopakumar-Vafa duality). In the B-model, certain types of matrix models are related on the gravity side to topological strings on certain cousins of the deformed conifold (Dijkgraaf-Vafa duality). In both cases, and similarly to the more physical AdS/CFT correspondence, the duality can be discovered by realizing the gauge theory as the target space theory of open strings ending on particular D-branes in a geometry closely related to the closed string background of the gravity theory. The A-branes supporting Chern Simons theory are wrapped on the Lagrangian three

    This second edition of the popular book written by Quang Ho-Kim, Narenda Kumar and Chi Sing Lam, provides a comprehensive and interesting view of ten important topics in modern physics. All the sections have been updated: symmetry, lasers, superconductivity, chaos and fractals, stellar evolution, elementary particles and cosmology, while three new sections have been added to this edition: Bose-Einstein condensates, nanostructures and quantum computation. It is an impressive feat by the authors to cover such a wide panorama of physics from particles to cosmos and at a consistently high scientific level of information and explanation. This level is excellent and is at the frontier of current research but it does mean that some parts may be quite difficult for the undergraduate student. The ideal reader is probably the mature physicist revisiting familiar lines of thought, and following amazing bridges between distant topics. And if you are an active specialist in one particular topic, this book would give a clear insight on subjects outside your own field, allowing you to at last understand what your university colleague is really doing in a branch of physics with which you are totally unfamiliar. At the beginning, the style of writing can be disconcerting at this scientific level; equations are almost systematically avoided and illustrations are sparse, which can occasionally make the discussions rather ponderous, but the remarkable level of pedagogy and imaginative conception more than compensates for this. The fundamental ideas of exciting natural phenomena are elegantly discussed, while the authors never forget that physics is an experimental science, and address up-to-date applications in this manner. A brief bibliography is added at the end of each chapter, and a few simple exercises are given with answers. But the great strength of this book, and the main reason why it is worth reading by anyone interested in modern science, lies in the text itself which

    Cosmology is a discipline that encompasses many diverse aspects of physics and astronomy. This is part of its attraction, but also a reason why it is difficult for new researchers to acquire sufficient grounding to enable them to make significant contributions early in their careers. For this reason there are many cosmology textbooks aimed at the advanced undergraduate/beginning postgraduate level. Physical Foundations of Cosmology by Viatcheslav Mukhanov is a worthy new addition to this genre. Like most of its competitors it does not attempt to cover every single aspect of the subject but chooses a particular angle and tries to unify its treatment around that direction. Mukhanov has chosen to focus on the fundamental principles underlying modern cosmological research at the expense of some detail at the frontiers. The book places great emphasis on the particle-astrophysics interface and issues connected with the thermal history of the big-bang model. The treatment of big-bang nucleosynthesis is done in much more detail than in most texts at a similar level, for example. It also contains a very extended and insightful discussion of inflationary models. Mukhanov makes great use of approximate analytical arguments to develop physical intuition rather than concentrating on numerical approaches. The book is quite mathematical, but not in a pedantically formalistic way. There is much use of 'order-of-magnitude' dimensional arguments which undergraduate students often find difficult to get the hang of, but which they would do well to assimilate as early as possible in their research careers. The text is peppered with problems for the reader to solve, some straightforward and some exceedingly difficult. Solutions are not provided. The price to be paid for this foundational approach is that there is not much about observational cosmology in this book, and neither is there much about galaxy formation or large-scale structure. It also neglects some of the trendier recent

    The evaporation of a black hole formed by the collapse of matter is a nonunitary process involving loss of information. At least, this is how it appears in Hawking's semiclassical description, in which gravity is not quantized and the emergent radiation appears thermal. Since unitarity is one of the pillars of quantum mechanics there has been an understandable reluctance to accept this as an ironclad conclusion. Conformal field theories in flat space are manifestly unitary, and the AdS/CFT correspondence therefore suggests that the information trapped in the depths of the hole must find some way to escape—a conclusion almost universally accepted today, at least among particle theorists. Just how it could escape remains a mystery, however, since nothing can escape without violating causality until the black hole has shrunk too far to hold much information. Gerard 't Hooft and the senior author of this book, Leonard Susskind, have been vocal advocates of the view that the information paradox poses a real crisis for physics requiring significant paradigm shifts. They suggest that locality must be given up as an objective property of physical phenomena (even on large scales) and replaced by a new principle of 'black hole complementarity'. Specifically, there are two very different ways to view the process of collapse and evaporation. To a free-falling observer, nothing unusual happens at the horizon and matter and information fall deep into the hole. To a stationary observer hovering just outside the hole it appears instead that the matter and information are deposited on the horizon (which he experiences as very hot because of his large acceleration), to be eventually re-emitted from there as Hawking radiation. According to 't Hooft and Susskind, these must be viewed as equally valid, 'complementary' descriptions of the same process. Black hole complementarity is essentially the statement (supported by operational arguments) that their simultaneous validity cannot

    These colloquium proceedings will be valuable, the blurb says, for graduate students and researchers in cosmology and theoretical astrophysics. Specifically, the book 'looks at both the strengths and weaknesses of the current big bang model in explaining certain puzzling data' and gives a 'comprehensive coverage of the expanding field of cosmology'. The reality is rather different. Conference proceedings rarely compare in value with a solid monograph or good review articles, and Current Issues in Cosmology is no exception. The colloquium was convened by the two editors, who have both long harboured doubts about the big bang, and was held in Paris in June 2004. The proceedings contain 19 presented papers and relatively brief summary comments by four panel speakers. The questions and answers at the end of each talk and a general discussion at the end were recorded and transcribed but contain little of interest. The nature of the colloquium is indicated by panellist Francesco Bertola's comment: 'While in the 1950s it was possible to speak of rival theories in cosmology, now the big-bang picture has no strong rivals. This is confirmed by the fact that out of 1500 members of the IAU Division VIII (Galaxies and the Universe) only a dozen, although bright people, devote their time to the heterodox views.' This was largely a platform for them to give their views. At least half of the dozen, all the 'usual suspects', were present: Geoffery and Margaret Burbidge, Jayant Narlikar, Halton Arp, Chandra Wickramasinghe and, in spirit only but playing a role somewhat like the ghost of Hamlet's father, the late Fred Hoyle. Doubters presented 12 of the 19 papers. Orthodoxy should certainly be challenged and the sociology of science questioned, but I found two main problems with this book. The papers putting the orthodox view are too short, even perfunctory. The most that a serious graduate student would get out of them is a reference to a far better review article or book on modern

    The motion of a charged particle interacting with its own electromagnetic field is an area of research that has a long history; this problem has never ceased to fascinate its investigators. On the one hand the theory ought to be straightforward to formulate: one has Maxwell's equations that tell the field how to behave (given the motion of the particle), and one has the Lorentz-force law that tells the particle how to move (given the field). On the other hand the theory is fundamentally ambiguous because of the field singularities that necessarily come with a point particle. While each separate sub-problem can easily be solved, to couple the field to the particle in a self-consistent treatment turns out to be tricky. I believe it is this dilemma (the theory is straightforward but tricky) that has been the main source of the endless fascination. For readers of Classical and Quantum Gravity, the fascination does not end there. For them it is also rooted in the fact that the electromagnetic self-force problem is deeply analogous to the gravitational self-force problem, which is of direct relevance to future gravitational wave observations. The motion of point particles in curved spacetime has been the topic of a recent Topical Review [1], and it was the focus of a recent Special Issue [2]. It is surprising to me that radiation reaction is a subject that continues to be poorly covered in the standard textbooks, including Jackson's bible [3]. Exceptions are Rohrlich's excellent text [4], which makes a very useful introduction to radiation reaction, and the Landau and Lifshitz classic [5], which contains what is probably the most perfect summary of the foundational ideas (presented in characteristic terseness). It is therefore with some trepidation that I received Herbert Spohn's book, which covers both the classical and quantum theories of a charged particle coupled to its own field (the presentation is limited to flat spacetime). Is this the text that graduate students

    Quantum mechanics is one of the most successful theoretical structures in all of science. Developed between 1925-26 to explain the optical spectrum of atoms, the theory over the succeeding 80 years has been extended, first to quantum field theories, gauge field theories, and now even string theory. It is used every day by thousands of physicists to calculate physical phenomena to exquisite precision, with no ambiguity in the results. To claim that this is a theory which is not understood by those physicists is absurd. And yet, as eminent a physicist as Richard Feynman, who did as much as anyone else to extend quantum theory to field theories and was a master at producing those exquisite calculations, could say that anyone who claimed they understood quantum theory clearly did not understand quantum theory. One hundred years ago Einstein postulated one of the most unsettling features of the theory, the wave-particle duality, with his particulate explanation for light of the photoelectric effect, and an explanation which was in direct conflict with Maxwell's brilliant development of a wave, or field, theory of light. Einstein believed that the particulate nature would ultimately be explainable by some sort of non-linear theory of electromagnetism, and was outraged by the acceptance of the community of the probabilistic quantum theory. His programme was of course dealt a (near?) fatal blow by Bell's discovery that the three desiderata - a theory which agrees with experiment, a theory which is local in its effects, and a theory in which nature, at its heart, is not probabilistic - are incompatible. That discomfort felt by Einstein and by Feynman is felt by numerous other people as well. This discomfort is heightened by the fact that the theory of gravity, another of Einstein's great achievements, has resisted all efforts at reconciliation with quantum mechanics. This book explores that discomfort, and tries to pin down what the locus of that discomfort is. For many

    Here are two textbooks, both published by Springer and each roughly half devoted to cosmology—the large scale structure and evolution of the Universe. I can imagine a context (not the same context) in which each would be useful. And there the similarities largely end. Bergstrom and Goobar's (hereafter B&G) other topic is particle astrophysics, and they are addressing students who already have some knowledge of advanced quantum mechanics and classical field theory (or who can master some relativistic dynamics and the Dirac equation on the basis of a couple of very information-dense appendices). The book is meant for use at the graduate level, probably the second year by US standards (the authors are from Stockholm). Schneider (hereafter PS), on the other hand, begins with galaxies, and then alternates between cosmological topics of gradually increasing sophistication (expanding universe to CMB fluctuations) and additional galactic topics—clusters, quasars and all. The book is meant as the second half of an introductory astronomy/astrophysics course for physics majors, and in the US would fit into an upper division `capstone' course. Each is meant for a single semester class at the target level, and might be squeezed into a 10-week term with elimination of some topics. B&G is a paperback of a second edition, with colour confined to a central block of plates, relatively few graphs and drawings, but lots of complex equations. PS is a hard cover translation from a German original, with colour used freely in astronomical images and graphs throughout, with fewer and less complex equations. Though the nominal difference in copyright date is only two years (2006 for PS, 2004 for B&G), the former is considerably more up to date, mentioning, for instance, that the third year WMAP results are not different enough from the first year to justify redoing drawings and such (I agree). What can you expect to get if you buy one or both of these? B&G have a homepage of error

    In 1952, Mme Yvonne Choquet-Bruhat published a major paper, Théorème d'existence pour certains systèmes d'équations aux dérivées partielles non linéaires (Acta Math. 88 141-225), which laid the foundation for modern studies of the Cauchy problem in general relativity. The fiftieth anniversary of this event was celebrated with an eponymous Cargèse Summer School in 2002. The proceedings of that summer school are summarized electronically (as audio, video, transparencies and lecture notes, where available) on a DVD archive included with this volume, and are also available on the internet. However the organizers decided that a separate volume describing the 'state of the art in mathematical general relativity' would be useful, and this book is the result. It includes some material not covered in the school and excludes some school material which has been covered adequately elsewhere. Unfortunately, I was unable to find, electronically, a table of contents, which every prospective purchaser would wish to see, and so this review does in fact list all the articles, ordered, roughly, by length. About one fifth of the book is devoted to a survey of Smoothness at Null Infinity and the Structure of Initial Data by Helmut Friedrich. This is a modern study of gravitational radiation, and the analysis of Einstein's equations. It is extremely helpful to survey all of this material, including some of the latest developments, using a consistent notation. This article is strongly recommended to anyone hoping to gain a foothold in this area. Note also that 47 pages of transparencies have become 84 book pages. Lars Andersson has surveyed, in The Global Existence Problem in General Relativity, some results and conjectures about the global properties of 3+1-dimensional spacetimes with a compact Cauchy surface. Again it is very useful to have essentially all of the known results presented in a consistent notation. This material is not on the DVD. Yvonne Choquet-Bruhat has

    ), but the latter is surprising in the context of a subject whose whole purpose is to observe the properties of primordial perturbations that may have arisen from inflation. Instead, the text concentrates on the technical heartland of the transport theory for CMB photons, and the Newtonian and relativistic theory for the development of CMB anisotropies, including polarization. It closes with more observationally-based chapters on general statistical aspects of the CMB sky, a digest of the recent results from WMAP, and an outlook. These are welcome, but the book really stands or falls on its treatment of the core physics of anisotropies. Without going too much into specifics, it can be fairly stated that the treatment given of the main material on CMB fluctuations is geared more to working professionals than to students. There is a good deal of useful technical detail, but it is not always derived systematically, and sometimes arises by reference to the research literature. There are no problem sets or worked examples, and not much attempt at intuitive illumination. As an example, one might point to the large-angle anisotropies of the CMB, which were first analysed in the classic Sachs Wolfe paper of 1967. The relativistic transport equation is there, but one looks in vain for the separation into the Sachs Wolfe effect proper (potential perturbations at last scattering) and the integrated effect of evolution since then. This latter ISW effect is in fact of huge interest in current research, since it is one of the methods for probing whether the vacuum energy differs from a cosmological constant. In general, the text seems strangely patchy on issues of contemporary interest, certainly in terms of its emphasis. It is as if the three authors contributed material separately without achieving a full integration. On the more positive side, the book has the advantage that it presents a Russian view of the subject. So much of the initial work on the `Relic Radiation' (a much

    The present volume is an introduction to general relativity and cosmology, at a level suitable for beginning graduate students or advanced undergraduates. The book consists of two main parts, the first entitled `Elements of differential geometry', and the second `The theory of gravitation'. Chapters 2-7, part I, introduce the basic ideas of differential geometry in a general setting, and are based on previously unpublished notes by one of the authors. On the one hand, the treatment is modern in that it uses a `top-down' approach, i.e. starting with general differentiable manifolds, and deferring the introduction of a metric tensor until after the notions of affine connection and curvature have been introduced. On the other hand, the treatment is classical in that it relies heavily, though not exclusively, on index notation. The general material, chapters 1-7, is then followed by four more specialized chapters dealing with matters of specific interest for general relativity. Topics include symmetry groups acting on Riemannian manifolds, with spherically symmetric spacetimes and spatially homogeneous spacetimes as examples, the efficient calculation of curvature, and the Petrov classification of the Weyl curvature tensor using spinors. Part II deals with general relativity and cosmology. The basic assumptions of the theory and its application to spherically symmetric gravitational fields are discussed in two chapters, and there is some historical material and motivation for the basic assumptions at the beginning of the book. The final chapter contains a detailed discussion of the Kerr solution. But the main emphasis in part II is on relativistic cosmology, in particular the analysis of cosmological models more general than the familiar Friedmann-Lemaitre (FL) models. The material on cosmology begins with a discussion of relativistic hydrodynamics and thermodynamics. The kinematical quantities (rate of expansion, shear, etc, of a timelike congruence) are introduced
