    Margins are developed for equipment susceptible to malfunction due to excessive time or operation cycles, and for identifying limited life equipment so monitoring and replacing is accomplished before hardware failure. Method applies to hardware where design service is established and where reasonable expected usage prediction is made.

    Ecosystem services mapping and modeling has focused more on supply than demand, until recently. Whereas the potential provision of economic benefits from ecosystems to people is often quantified through ecological production functions, the use of and demand for ecosystem services has received less attention, as have the spatial flows of services from ecosystems to people. However, new modeling approaches that map and quantify service-specific sources (ecosystem capacity to provide a service), sinks (biophysical or anthropogenic features that deplete or alter service flows), users (user locations and level of demand), and spatial flows can provide a more complete understanding of ecosystem services. Through a case study in Puget Sound, Washington State, USA, we quantify and differentiate between the theoretical or in situ provision of services, i.e., ecosystems’ capacity to supply services, and their actual provision when accounting for the location of beneficiaries and the spatial connections that mediate service flows between people and ecosystems. Our analysis includes five ecosystem services: carbon sequestration and storage, riverine flood regulation, sediment regulation for reservoirs, open space proximity, and scenic viewsheds. Each ecosystem service is characterized by different beneficiary groups and means of service flow. Using the ARtificial Intelligence for Ecosystem Services (ARIES) methodology we map service supply, demand, and flow, extending on simpler approaches used by past studies to map service provision and use. With the exception of the carbon sequestration service, regions that actually provided services to people, i.e., connected to beneficiaries via flow paths, amounted to 16-66% of those theoretically capable of supplying services, i.e., all ecosystems across the landscape. These results offer a more complete understanding of the spatial dynamics of ecosystem services and their effects, and may provide a sounder basis for economic

    Recent ecosystem services research has highlighted the importance of spatial connectivity between ecosystems and their beneficiaries. Despite this need, a systematic approach to ecosystem service flow quantification has not yet emerged. In this article, we present such an approach, which we formalize as a class of agent-based models termed “Service Path Attribution Networks” (SPANs). These models, developed as part of the Artificial Intelligence for Ecosystem Services (ARIES) project, expand on ecosystem services classification terminology introduced by other authors. Conceptual elements needed to support flow modeling include a service's rivalness, its flow routing type (e.g., through hydrologic or transportation networks, lines of sight, or other approaches), and whether the benefit is supplied by an ecosystem's provision of a beneficial flow to people or by absorption of a detrimental flow before it reaches them. We describe our implementation of the SPAN framework for five ecosystem services and discuss how to generalize the approach to additional services. SPAN model outputs include maps of ecosystem service provision, use, depletion, and flows under theoretical, possible, actual, inaccessible, and blocked conditions. We highlight how these different ecosystem service flow maps could be used to support various types of decision making for conservation and resource management planning.

    Rocky Flats Environmental Technology Site (RFETS), has approximately 10,000 High Efficiency Particulate Air (HEPA) Filters installed in a variety of filter plenums. These ventilation/filtration plenum systems are used to control the release of airborne particulate contaminates to the environment during normal operations and potential accidents. This report summarizes the results of destructive and non-destructive tests on HEPA filters obtained from a wide variety of ages and service conditions. These tests were performed to determine an acceptable service life criteria for HEPA filters used at Rocky Flats Environmental Technology Site (RFETS). A total of 140 filters of various ages (1972 to 1996) and service history (new, aged unused, used) were tested. For the purpose of this report, filter age from manufacture date/initial test date to the current sample date was used, as opposed to the actual time a filter was installed in an operating system.

    A review of the Savannah River Site production reactor systems was initiated in 1980 and led to implementation of the Reactor Materials Program in 1984 to assess reactor safety and reactor service life. The program evaluated performance of the reactor tanks, primary coolant piping, and thermal shields, components of welded construction that were fabricated from Type 304 stainless steel. The structural integrity analysis of the primary coolant system has shown that the pressure boundary is not susceptible to gross rupture, including a double ended guillotine break or equivalent large area bank. Residual service life is potentially limited by two material degradation modes, irradiation damage and intergranular stress corrosion cracking. Analysis of the structural integrity of the tanks and piping has shown that continued safe operation of the reactors for several additional decades is not limited by the material performance of the primary coolant system. Although irradiation damage has not degraded material behavior to an unacceptable level, past experience has revealed serious difficulties with repair welding on irradiated stainless steel. Stress corrosion can be mitigated by newly identified limits on impurity concentrations in the coolant water and by stress mitigation of weld residual stresses. Work continues in several areas: the effects of helium on mechanical behavior of irradiated stainless steel; improved weld methods for piping and the reactor tanks; and a surveillance program to track irradiation effects on the tank walls.

    Maritime vessels have long service life and great costs of building, manning, operating, maintaining and repairing throughout their life. Major actions are needed to repair, renovate, sometime built or even replace those scrapped when technology or demand changes determine obsolescence. It is regarded as a concern throughout vessel's entire life cycle and reflects changes in expectation regarding performances in functioning, safety and environmental effects. While service live may differ from physical lives, expectations about physical lives is the main factors that determines design service life. Performance and failure are illustrated conceptually and represented in a simplified form considering the evolution of vessels parameters during its service life. In the proposed methodology an accumulated vessel lifecycle cost is analyzed and obsolescence is characterized from ship's design, performances, maintenance and management parameters point of view. Romanian ports feeding Black Sea are investigated in order to provide comprehensive information on: number and types of vessels, transport capacity and life cycle length. Recommendations are to be made in order to insure a best practice in lifecycle management in order to reduce costs.

    A visiting interview survey was performed on all centenarians living in Japan to investigate their Activities of Daily Life (ADL). 2,851 centenarians, 92.9% of all subjects completed the interview. They were divided into three groups, good ADL (almost independent in daily life), moderate ADL (almost independent in indoor life), and inferior ADL (bed fast) by the condition of ADL. Some factors of health conditions, family size, frequency of use of public welfare services, and life styles were compared among these three groups. Both the good and the moderate ADL groups accounted for about 20% each, and the inferior ADL group was about 60% of the subjects. The condition of ADL of men was better than that of women. The inferior ADL group showed a significantly higher percentage of chronic diseases. High ratios of cerebral vascular disease and dementia were seen in this group, and many had no teeth. While two thirds of all the centenarians lived at home, over 90% of the good ADL group lived at home. The mode of family size was three including the person oneself. An average of 21% of men and 27% of women used public health welfare services. However 40% of the centenarians in the inferior ADL group used those services. Men had better dietary habits for health than women. The good ADL group showed the most desirable dietary habits among the three groups and had the highest percentage of drinkers and smokers. Men practiced a greater number of ideal habits for longevity than women. Of the ADL groups, centenarians in the good ADL group had the highest percentage of ideal habits for longevity. The centenarians who maintained good ADL had the following characteristics: There were fewer people under medical treatment. They had maintained their own teeth. Almost all of them were living at their home with their family. They had continued good dietary habits and daily life for health and longevity. For the maintenance and improvement of ADL of centenarians, adequate social welfare

    Nuclear power plants are providing, currently, about 17 percent of the U.S. electricity and many of these plants are approaching their licensed life of 40 years. The U.S. Nuclear Regulatory Commission and the Department of Energy`s Oak Ridge National Laboratory are carrying out a program to develop a methodology for assessing the remaining safe-life of the concrete components and structures in nuclear power plants. This program has the overall objective of identifying potential structural safety issues, as well as acceptance criteria, for use in evaluations of nuclear power plants for continued service. The National Institute of Standards and Technology (NIST) is contributing to this program by identifying and analyzing methods for predicting the remaining life of in-service concrete materials. This report examines the basis for predicting the remaining service lives of concrete materials of nuclear power facilities. Methods for predicting the service life of new and in-service concrete materials are analyzed. These methods include (1) estimates based on experience, (2) comparison of performance, (3) accelerated testing, (4) stochastic methods, and (5) mathematical modeling. New approaches for predicting the remaining service lives of concrete materials are proposed and recommendations for their further development given. Degradation processes are discussed based on considerations of their mechanisms, likelihood of occurrence, manifestations, and detection. They include corrosion, sulfate attack, alkali-aggregate reactions, frost attack, leaching, radiation, salt crystallization, and microbiological attack.

    The International Space Station (ISS) uses high-efficiency particulate air filters to remove particulate matter from the cabin atmosphere. Known as bacteria filter elements (BFEs), there are 13 elements deployed on board the ISS's U.S. segment in the flight 4R assembly level. The preflight service life prediction of 1 yr for the BFEs is based upon engineering analysis of data collected during developmental testing that used a synthetic dust challenge. While this challenge is considered reasonable and conservative from a design perspective, an understanding of the actual filter loading is required to best manage the critical ISS program resources. Testing was conducted on BFEs returned from the ISS to refine the service life prediction. Results from this testing and implications to ISS resource management are provided.

    This paper is focused on the estimation of durability and service life of reinforced concrete structures. Assuming that the chloride ion in concrete can be absorbed on tricalcium aluminate, calcium silicate hydrate, and by other constituents of hardened cement paste, hydrated or not, the exact analytical solution of the governing partial differential equation together with its boundary and initial conditions can be obtained through nondimensional parameters and Laplace's transform. When the results of an exact analytical solution using suitable parameters were compared with the results of previous experimental work, the differences were found to be very small. This suggests that the absorption model is of considerable value. The exact analytical solution with the saturation parameter and time and diffusion coefficients under different effective electrical potential could be used to predict both the experimental results and the service life of reinforced concrete structures.

    To lengthen production runs, a Canadian ethylene operator experimented with a coating system to protect a critical compressor`s rotor from hydrocarbon-polymerization/fouling. In ethylene manufacturing, compressor fouling is an accepted ``fact of life.`` Past attempts to minimize fouling in the crack-gas compression train were unsuccessful or marginally cost-effective. Applying protective coatings to a critical-service ethylene compressor rotor slowed oiling, thus lengthening the production run time by one year.

    To date there is no NIOSH-approved air-purifying respirator which will effectively remove formaldehyde gas. Because of formaldehyde's high vapor pressure, service life values calculated using the adsorption isotherm and Wheeler equations indicate that organic vapor cartridges containing activated carbon will last less than 10 minutes at concentrations greater than 10 ppM. Studies were initiated to identify a suitable sorbent for this potentially dangerous material. The project involves the following steps: develop a method for producing relatively high concentrations (20 ppM) of a formaldehyde test mixture; verify this test concentration using the NIOSH-approved chromotropic acid wet chemical technique; and survey a wide variety of sorbents, both plain and impregnated, in hopes of identifying a suitable air-purifying cartridge for formaldehyde. A dynamic formaldehyde generation system was fabricated in which formaldehyde was produced by continuously injecting formalin using a syringe pump. The concentration was monitored using an infrared analyzer and checked using the chromotropic acid technique. Twenty-five cartridges were tested for service life at concentrations of formaldehyde gas from 7.1 to 14.8 ppM. Acid gas cartridges and those containing Pittsburgh FCA or ASC showed superior service life.

    The measurement of temperature within slagging gasifiers for long periods of time is difficult/impossible because of sensor failure or blockage of inputs used to monitor gasifier temperature. One of the most common means of temperature measurement in a gasifier is physically, through the use of thermocouples in a gasifier sidewall. These units can fail during startup, standby, or during the first 40-90 days of gasifier service. Failure can be caused by a number of issues; including thermocouple design, construction, placement in the gasifier, gasifier operation, and molten slag attack of the materials used in a thermocouple assembly. Lack of temperature control in a gasifier can lead to improper preheating, slag buildup on gasifier sidewalls, slag attack of gasifier refractories used to line a gasifier, or changes in desired gas output from a gasifier. A general outline of thermocouple failure issues and attempts by the Albany Research Center to improve the service life of thermocouples will be discussed.

    The aim of this study was to estimate the shelf life of butter and cheese products, with shelf life being a guide used to determine the storage period of food before deterioration. Butter and cheese samples stored at 10℃ and 15℃ had a shelf life of 221 d, while those stored at 25℃ and 35℃ had a shelf life of 109 d. Quality changes, including total cell count, coliform counts, Listeria monocytogenes counts, acid value, moisture content, pH, acidity and overall sensory evaluation, were monitored. In order to pass the overall sensory evaluation, a quality score of 5 points on a 9-point scale was required. For other quality criteria, legal quality limits were established based on the “Process Criteria and Ingredient Standard of Livestock Products” by the Animal, Plant and Fisheries Quarantine and Inspection Agency (Republic of Korea). The nonlegal quality limit was estimated by regression analysis between non-quality criteria (y) and overall sensory evaluation (x). The shelf life was estimated based on the number of days that the product passed the quality limit of the quality criteria. The shelf life of samples stored at 10℃, 15℃, 25℃ and 35℃ was 21.94, 17.18, 6.10 and 0.58 mon, respectively, for butter and 10.81, 9.47, 4.64 and 0.20 mon, respectively, for cheese. PMID:26760945

    Service life extension of explosive devices used in aircraft escape systems can achieve considerable savings. An overall approach is needed to challenge the logic of explosive component service extension from design to removal from service for evaluation. The purpose of the effort described in this paper was to develop a service-extension approach on explosive devices used in aircraft systems, supported by actual testing of representative candidate devices, to evaluate quantitatively the effects of service, age, and degradation, and allow responsible, conservative service life determinations. Evaluated were five explosive components: rigid and flexible explosive transfer lines, one-way transfers, flexible linear shaped charges, and initiation handles. The service extension approach generated in this effort is summarized by eight recommendations.

    The service life extension of solid propulsion systems, subsystems, and components will be discussed based on the service life extension of the Space Transportation System Reusable Solid Rocket Motor (RSRM) and Booster Separation Motors (BSM). The RSRM is certified for an age life of five years. In the aftermath of the Columbia accident there were a number of motors that were approaching the end of their five year service life certification. The RSRM Project initiated an assessment to determine if the service life of these motors could be extended. With the advent of the Constellation Program, a flight test was proposed that would utilize one of the RSRMs which had been returned from the launch site due to the expiration of its five year service life certification and twelve surplus Chemical Systems Division BSMs which had exceeded their eight year service life. The RSRM age life tracking philosophy which establishes when the clock starts for age life tracking will be described. The role of the following activities in service life extension will be discussed: subscale testing, accelerated aging, dissecting full scale aged hardware, static testing full scale aged motors, data mining industry data, and using the fleet leader approach. The service life certification and extension of the BSMs will also be presented.

    Aims and method To develop a simple, pragmatic typology to characterise the nature of liaison interventions delivered by a liaison service in a National Health Service setting. We carried out a retrospective electronic case-note review of referrals to a ward-based liaison psychiatry service. Results Three hundred and forty-four patients were referred to the service over a 12-month period. Ten different types of liaison interventions were identified, with the most common interventions being diagnosis (112 patients, 32.6%), medication management (57 patients, 16.6%), risk assessment and treatment (56 patients, 16.3% each). Mental Health Act work accounted for the greatest number of contacts per patient (median 7). Clinical implications There are inherent limitations in any single-site observational study, as site-specific results cannot be generalised to other liaison services. The intervention categories we developed, however, are easy to use and will provide a way of comparing and benchmarking the range of interventions delivered by different liaison psychiatry services.

    The behavior of lead-free solder alloys under complex loading scenarios is still not well understood. Common damage accumulation rules fail to account for strong effects of variations in cycling amplitude, and random vibration test results cannot be interpreted in terms of performance under realistic service conditions. This is a result of the effects of cycling parameters on materials properties. These effects are not yet fully understood or quantitatively predictable, preventing modeling based on parameters such as strain, work, or entropy. Depending on the actual spectrum of amplitudes, Miner's rule of linear damage accumulation has been shown to overestimate life by more than an order of magnitude, and greater errors are predicted for other combinations. Consequences may be particularly critical for so-called environmental stress screening. Damage accumulation has, however, been shown to scale with the inelastic work done, even if amplitudes vary. This and the observation of effects of loading history on subsequent work per cycle provide for a modified damage accumulation rule which allows for the prediction of life. Individual joints of four different Sn-Ag-Cu-based solder alloys (SAC305, SAC105, SAC-Ni, and SACXplus) were cycled in shear at room temperature, alternating between two different amplitudes while monitoring the evolution of the effective stiffness and work per cycle. This helped elucidate general trends and behaviors that are expected to occur in vibrations of microelectronics assemblies. Deviations from Miner's rule varied systematically with the combination of amplitudes, the sequences of cycles, and the strain rates in each. The severity of deviations also varied systematically with Ag content in the solder, but major effects were observed for all the alloys. A systematic analysis was conducted to assess whether scenarios might exist in which the more fatigue-resistant high-Ag alloys would fail sooner than the lower-Ag ones.

    The Missouri Pro-Life Nurses claim that nurses have lost the ethical basis of their profession. Nurses need to reexamine their attitudes at a time when 1 in 5 physician-members of the American Society of Internal Medicine admits to deliberately helping a patient end his or her life, and when many physicians and nurses favor euthanasia and abortion. Former Georgia nurse Joseph Dewey Akin was sentenced in October 1992 to life imprisonment for injecting Robert Price, a quadriplegic, with a lethal dose of lidocaine. Hospice nurse Darlene Leon of California is on trial for injecting 17 of her patients with lethal doses of morphine. A nurse from Georgia was indicted on one count of aggravated assault for attempting to kill her 87-year-old patient with an injection of potassium. Georgia nurse Jenny Serbes was charged with murder in the death of her husband with a lethal injection of insulin. The fierce argument about abortion and euthanasia now raging in America is this century's civil war. 20 years ago, in an effort to combat this tide, the National Association of Pro-Life Nurses (NAPN) was started, and its 1000 members want to demonstrate positive concern for all human life. NAPN attempts to educate nurses and the health care community on the legal and medical aspects of the ethical issues facing the profession. In October 1993 the first meeting of Illinois Pro-Life Nurses was held in suburban Chicago. The nurse-patient relationship can be viewed as a contract. Implicit in this relationship is the understanding that the nurse will do no harm. If the relationship is broken, the foundation on which nursing and medicine rest is shaken. Pro-life nursing organizations are trying to steer the nursing profession back on the right course.

    Japanese Industrial Health Organizations (IHOs) have been taking part in medical checkups for employees in accordance with the law of industrial safety and health in Japan. We carried out a questionnaire survey for each IHO in order to learn the actual number of full-time doctors and their proportion of work time. We sent a questionnaire to 112 IHOs (members of International Federation of Industrial Health Organizations) by mail, of which 77 replied (68.8%). In addition, we carried out an interview survey in 3 IHOs. The actual number of full-time doctors was 0 to 51, about half of IHOs have less than 5 doctors/each. Regarding the proportion of work time, among full-time doctors, half of them take part in general health checkups. About 70% of nurses' work time is taken up doing health checkups. The results revealed that the number and the proportion of work time of full-time doctors depends on the characteristics of the area and the background of the organization, for instance, what kind of hygiene services they provide. Depending on the doctors' work style (e.g. full-time or part-time) and their specialities and experience, their work may be shared. Japanese employers are required to report the number of workers with abnormal findings found by medical checkups to the Labor Standards Office. Many IHOs provide service to employers in filling out their reports. Thus, we also asked each IHO about this service. Forty out of the 77 IHOs (51.9%) answered that they are providing statistical analysis and the filling-out service. They count the number of workers with abnormal findings in each company and helped the employer to fill out the report form. Twenty-nine of those 40 IHOs responded that they decided which findings were "abnormal" by using only items that are set by law. However, 7 IHOs reported the fact that they also add some optional items when making the decision. The prevalence of workers with abnormal findings in annual medical checkups, which is one of the

    Differential-pressure transducer includes a piston, helical springs, and a linear variable-differential transformer concentric with piston. Transducer senses motion of piston in response to changes in pressure differential. Eight seals within the transducer prevent fluid leakage from one pressure line to the other. Reliability and operating life of the new unit are superior to many conventional transducers.

  10. Evaluation of Hose in Hose transfer line service life

    SciTech Connect

    EAGLE, O.H.

    2003-05-30

    This document presents a determination for the amount of expected service life from Hose-in-Hose Transfer Lines based on vendor information and past HIHTL experience. Based on the information presented in this report and referenced documentation, we conclude the service life of the inner hose establishes the limits of service life for the finished assemblies. Since the process and environmental conditions to which the transfer line is subjected will not adversely affect the hose, the effective service life is that stated by the vendor--three years from the date of initial transfer. Transfer line assemblies have a shelf life of seven years from the date of hose manufacture, if stored in accordance with Section 2.1. This evaluation provides documentation showing that a three year service life has been justified. In the event that transfer lines are to be operated after three years from the date of initial transfer and within the shelf life of seven years, they must be reevaluated for their ability to perform intended functions.

    Current concepts of the nature of fatigue failure at low temperatures are presented on the basis of experimental results of various investigators. The fundamental approach to the technique for studying low-temperature fatigue is examined. The necessity for using the same medium at different fatigue test temperatures and also the necessity for taking into account the magnitude of the plastic deformation amplitude are confirmed. Experimental data from a study of the influence of low temperatures (down to liquid nitrogen temperatures) on the fatigue life of copper and armco-iron in dry air, over a wide range of deformations, are presented. These results are compared with microscopic and electron microscopic pictures of the surface of the deformed specimens.

    1973-01-01

    Mercury ion thruster isolator lifetime tests were performed using different isolator materials and geometries. Tests were performed with and without the flow of mercury through the isolators in an oil diffusion pumped vacuum facility and cryogenically pumped bell jar. The onset of leakage current in isolators tested occurred in time intervals ranging from a few hours to many hundreds of hours. In all cases, surface contamination was responsible for the onset of leakage current and subsequent isolator failure. Rate of increase of leakage current and the leakage current level increased approximately exponentially with isolator temperature. Careful attention to shielding techniques and the elimination of sources of metal oxides appear to have eliminated isolator failures as a thruster life limiting mechanism.

    The role of stressful life events in the etiology of various disorders has been of interest to investigators attempting to establish a link between stressful life events and disorders. None of the available scales are relevant to service personnel. In the present study an attempt was made to construct a scale to measure stressful life events in service personnel. In the first stage of study open-ended questions along with items generated by the expert group by consensus method were administered to 50 soldiers. During the second stage the scale comprising of 59 items was administered in group setting to 165 service personnel. Weightage was assigned on 0-100 range Frequency of occurrence of life events within past one year and lifetime was also noted. Findings revealed that service personnel experience more number of life events within a year as well as in lifetime. Some general items, which are common to civilians are having consistency of weightage being assigned. There is a pattern of uniformity with the civilian counterparts along with differences in the items specific to service personnel. PMID:21407857

  17. Integrating service-life modeling and life-cycle assessment for recycled-aggregate concrete

    NASA Astrophysics Data System (ADS)

    Bergman, Todd Lee

    The development and implementation of one-dimensional (a) analytical and (b) numerical service-life models for chloride-induced corrosion of reinforced concrete containing both recycled-aggregates and supplementary cementitious materials (SCMs) are presented in this work. Both the analytical and numerical models account for initial chloride contamination levels due to previous applications. The effects of aggregate type (e.g., virgin, recycled aggregate, recycled mortar), aggregate replacement ratio, severity of chloride contamination levels, severity of in-service chloride exposure, reinforcement cover depth, SCM type (e.g., fly ash, slag, slice fume, metakaolin), and SCM replacement ratio on the expected service life of recycled-aggregate reinforced concrete were investigated. Results illustrated trends between concrete mixes and life cycle costs, which were employed to make conclusions on the trade-offs presented by cost, sustainability, and service life.

    The International Space Station (ISS) is a result of international collaboration in building a sophisticated laboratory of an unprecedented scale in Low Earth Orbit. After a complex assembly sequence spanning over a decade, some of the early modules launched at the beginning of the program would reach the end of their certified lives, while the newer modules were just being commissioned into operation. To maximize the return on global investments in this one-of-a-kind orbiting platform that was initially conceived for a service life until 2016, it is essential for the cutting edge research on ISS to continue as long as the station can be sustained safely in orbit. ISS Program is assessing individual modules in detail to extend the service life of the ISS to 2024, and possibly to 2028. Without life extension, Functional Cargo Block (known by its Russian acronym as FGB) and the Service Module (SM), two of the early modules on the Russian Segment, would reach the end of their certified lives in 2013 and 2015 respectively. Both FGB and SM are critical for the propulsive function of the ISS. This paper describes the approach used for the service life extension of the FGB propulsion system. Also presented is an overview of the system description along with the process adopted for developing the life test plans based on considerations of system failure modes, fault tolerance and safety provisions. Tests and analyses performed, important findings and life estimates are summarized. Based on the life extension data, FGB propulsion system, in general, is considered ready for a service life until 2028.

    Heart failure has high incidence and prevalence in the UK. However, access to palliative care services for patients with heart failure is inequitable. Patients with heart failure often do not receive specialist palliative care at the end of life, or referral is made only in the last days of life. This results in lost opportunities for advance care planning, psychological support for patients and families and symptom management. Prognostic tools are useful in ensuring appropriate referral. However, the controversy regarding the Liverpool Care Pathway has created uncertainty for healthcare professionals, patients and families. This article examines palliative care and end of life care services for patients with heart failure. It presents the case for service development and examines the benefits for patients who traditionally may not have had access to this care. PMID:25138875

    2003-01-01

    The International Space Station uses high efficiency particulate air (HEPA) filters to remove particulate matter from the cabin atmosphere. Known as Bacteria Filter Elements (BFEs), there are 13 elements deployed on board the ISS's U.S. Segment. The pre-flight service life prediction of 1 year for the BFEs is based upon performance engineering analysis of data collected during developmental testing that used a synthetic dust challenge. While this challenge is considered reasonable and conservative from a design perspective, an understanding of the actual filter loading is required to best manage the critical ISS Program resources. Thus testing was conducted on BFEs returned from the ISS to refine the service life prediction. Results from this testing and implications to ISS resource management are discussed. Recommendations for realizing significant savings to the ISS Program are presented.

    This paper describes a joint Army/NASA-sponsored research program on the service life evaluation of rigid explosive transfer lines. These transfer lines are used to initiate emergency crew escape functions on a wide variety of military and NASA aircraft. The purpose of this program was to determine quantitatively the effects of service, age, and degradation on rigid explosive transfer lines to allow responsible, conservative, service life determination. More than 800 transfer lines were removed from the U.S. Army AH-1G and AH-1S, the U.S. Air Force B-1 and F-111, and the U.S. Navy F-14 aircraft for testing. The results indicated that the lines were not adversely affected by age, service, or a repeat of the thermal qualification tests on full-service lines. Extension of the service life of rigid explosive transfer lines should be considered, since considerable cost savings could be realized with no measurable decrease in system reliability.

    1988-01-01

    The service longevity of complex propulsion systems, such as the Space Shuttle Main Engine (SSME), can be at risk from several competing failure modes. Conventional life assessment practice focuses upon the most severely life-limited feature of a given component, even though there may be other, less severe, potential failure locations. Primary, secondary, tertiary failure modes, as well as their associated probabilities, must also be considered. Futhermore, these probabilities are functions of accumulated service time. Thus a component may not always succumb to the most severe, or even the most probable failure mode. Propulsion system longevity must be assessed by considering simultaneously the actions of, and interactions among, life-limiting influences. These include, but are not limited to, high frequency fatigue (HFF), low cycle fatigue (LCF), and subsequent crack propagation, thermal and acoustic loadings, and the influence of less-than-ideal nondestructive evaluation (NDE). An outline is provided for a probabilistic model for service life analysis, and the progress towards its implementation is reported.

  12. Effects of Planetary Speed Reduction Ratio on Mean Service Life

    NASA Technical Reports Server (NTRS)

    Savage, M.; Rubadeux, K. L.; Coe, H. H.

    1998-01-01

    Planetary gear transmissions are compact speed reductions which use parallel-load paths to transmit high power. The range of possible reduction ratios is bounded from below and above by limits on the relative size of the planet gears. For a single plane planetary transmission, the speed-reduction ratio must be greater than two for planet gears to exist. As the ratio increase, so does the size of the planets relative to the sizes of the sun and ring. Which ratio is best for a planetary reduction can be resolved by studying a series of optimal designs. In this series, each design is obtained by maximizing the service life for a spur-gear planetary with a fixed size, speed reduction ratio, input speed, power and materials. The planetary gear reduction service life is modeled as a function of the two-parameter Weibull distributed service lives of the ball bearings and spur gears in the reduction. Planet-bearing life strongly influences the optimal reduction lives which point to an optimal planetary reduction ratio in the neighborhood of four to five.

  14. Managing the equipment service life in rendering engineering support to NPP operation

    2015-05-01

    Apart from subjecting metal to nondestructive testing and determining its actual state, which are the traditional methods used for managing the service life of NPP equipment during its operation, other approaches closely linked with rendering engineering support to NPP operation have emerged in recent decades, which, however, have been covered in publications to a lesser extent. Service life management matters occupy the central place in the structure of engineering support measures. Application of the concept of repairing NPP equipment based on assessing its technical state and the risk of its failure makes it possible to achieve significantly smaller costs for maintenance and repairs and produce a larger amount of electricity due to shorter planned outages. Decreasing the occurrence probability of a process-related abnormality through its prediction is a further development of techniques for monitoring the technical state of equipment and systems. The proposed and implemented procedure for predicting the occurrence of process-related deviations from normal NPP operation opens the possibility to record in the online mode the trends in changes of process parameters that are likely to lead to malfunctions in equipment operation and to reduce the probability of power unit unloading when an abnormal technical state of equipment occurs and develops by recording changes in the state at an early stage and taking timely corrective measures. The article presents the structure of interconnections between the objectives and conditions of adjustment and commissioning tests, in which the management of equipment service life (saving and optimizing the service life) occupies the central place. Special attention is paid to differences in resource saving and optimization measures.

  15. Aging mechanisms and service life of lead-acid batteries

    NASA Astrophysics Data System (ADS)

    Ruetschi, Paul

    In lead-acid batteries, major aging processes, leading to gradual loss of performance, and eventually to the end of service life, are: Anodic corrosion (of grids, plate-lugs, straps or posts). Positive active mass degradation and loss of adherence to the grid (shedding, sludging). Irreversible formation of lead sulfate in the active mass (crystallization, sulfation). Short-circuits. Loss of water. Aging mechanisms are often inter-dependent. For example, corrosion of the grids will lead to increased resistance to current flow, which will in turn impede proper charge of certain parts of the active mass, resulting in sulfation. Active mass degradation may lead to short-circuits. Sulfation may be the result of a loss of water, and so forth. The rates of the different aging processes strongly depend on the type of use (or misuse) of the battery. Over-charge will lead to accelerated corrosion and also to accelerated loss of water. With increasing depth-of-discharge during cycling, positive active mass degradation is accelerated. Some aging mechanisms are occurring only upon misuse. Short-circuits across the separators, due to the formation of metallic lead dendrites, for example, are usually formed only after (excessively) deep discharge. Stationary batteries, operated under float-charge conditions, will age typically by corrosion of the positive grids. On the other hand, service life of batteries subject to cycling regimes, will typically age by degradation of the structure of the positive active mass. Starter batteries are usually aging by grid corrosion, for instance in normal passenger car use. However, starter batteries of city buses, making frequent stops, may age (prematurely) by positive active mass degradation, because the batteries are subject to numerous shallow discharge cycles. Valve-regulated batteries often fail as a result of negative active mass sulfation, or water loss. For each battery design, and type of use, there is usually a characteristic

    . There are no representative ground test articles for some of the components. A 'test everything' approach would require manufacturing new test articles. The paper outlines some of the techniques used for selective testing, by way of cherry picking candidate components based on failure mode effects analysis, system level impacts, hazard analysis, etc. The type of testing required for extending the service life depends on the design and criticality of the component, failure modes and failure mechanisms, life cycle margin provided by the original certification, operational and environmental stresses encountered, etc. When specific failure mechanism being considered and the underlying relationship of that mode to the stresses provided in the test can be correlated by supporting analysis, time and effort required for conducting life extension testing can be significantly reduced. Exposure to corrosive propellants over long periods of time, for instance, lead to specific failure mechanisms in several components used in the propulsion system. Using Arrhenius model, which is tied to chemically dependent failure mechanisms such as corrosion or chemical reactions, it is possible to subject carefully selected test articles to accelerated life test. Arrhenius model reflects the proportional relationship between time to failure of a component and the exponential of the inverse of absolute temperature acting on the component. The acceleration factor is used to perform tests at higher stresses that allow direct correlation between the times to failure at a high test temperature to the temperatures to be expected in actual use. As long as the temperatures are such that new failure mechanisms are not introduced, this becomes a very useful method for testing to failure a relatively small sample of items for a much shorter amount of time. In this article, based on the example of the propulsion system of the first ISS module Zarya, theoretical approaches and practical activities of

  18. Mechanisms from models--actual effects from real life: the zero-calorie drink-break option.

    PubMed

    Booth, D A

    1988-01-01

    Animal and human laboratory models show that the suppression of appetite by a modest amount of readily assimilable energy, such as a caloric sweetener, is not likely to last longer than an hour. The transience of their satiating effect constitutes a mechanism whereby the sugars, starch, alcohol and fats in drinks and the snackfoods eaten with them could add to energy intake which is subsequently uncompensated and so contributes to weight gain. Conversely, if those in the habit of consuming such energy-containing drinks and accompaniments avoided such items or replaced them by low-calorie substitutes, this might help in weight reduction and even perhaps in prevention of obesity. The effectiveness of this "zero-calorie drink-break option" can be tested by correlating separately reported real-life eating habits and weight changes across people whose circumstances are similar. The existing field data indicate that the fatter a person is the more likely they are to use the conventional undifferentiated sugar-substitution strategies and also that these usually do not help weight reduction.

  19. Predicting in-service fatigue life of flexible pavements based on accelerated pavement testing

    NASA Astrophysics Data System (ADS)

    Guo, Runhua

    Pavement performance prediction in terms of fatigue cracking and surface rutting are essential for any mechanistically-based pavement design method. Traditionally, the estimation of the expected fatigue field performance has been based on the laboratory bending beam test. Full-scale Accelerated Pavement Testing (APT) is an alternative to laboratory testing leading to advances in practice and economic savings for the evaluation of new pavement configurations, stress level related factors, new materials and design improvements. This type of testing closely simulates field conditions; however, it does not capture actual performance because of the limited ability to address long-term phenomena. The same pavement structure may exhibit different response and performance under APT than when in-service. Actual field performance is better captured by experiments such as Federal Highway Administration's Long-Term Pavement Performance (LTPP) studies. Therefore, to fully utilize the benefits of APT, there is a need for a methodology to predict the long-term performance of in-service pavement structures from the results of APT tests that will account for such differences. Three models are generally suggested to account for the difference: shift factors, statistical and mechanistic approaches. A reliability based methodology for fatigue cracking prediction is proposed in this research, through which the three models suggested previously are combined into one general approach that builds on their individual strengths to overcome some of the shortcomings when the models are applied individually. The Bias Correction Factor (BCF) should account for all quantifiable differences between the fatigue life of the pavement site under APT and in-service conditions. In addition to the Bias Correction Factor, a marginal shifty factor, M, should be included to account for the unquantifiable differences when predicting the in-service pavement fatigue life from APT.

    Rocky Flats Environmental Technology Site (the Site) has approximately 10,000 High Efficiency Particulate Air (HEPA) Filters installed in a variety of filter plenums. These ventilation/filtration plenum systems are used to control the release of airborne particulate contaminates to the environment during normal operations and also during potential design-based accidents. The operational integrity of the HEPA filter plenums is essential to maintaining the margins of safety as required by building specific Final Safety Analysis Reports (FSARS) for protection of the public and environment. An Unreviewed Safety Question Determination (USQD), USDQ-RFP94.0615-ARS, was conducted in 1994 addressing the potential inadequacy of the safety envelope for Protected Area building HEPA plenums. While conducting this USQD, questions were raised concerning the maximum service life criteria for HEPA filters. Accident scenarios in existing FSARs identify conditions that could potentially cause plugging or damage of down stream HEPA filters as a result of impaction from failed filters. Additionally, available data indicates that HEPA filters experience structural degradation due to the effects of age. The Unresolved Safety Question (USQ) compensatory measures thus require testing and analysis of used HEPA filters in order to determine and implement service life criteria.

    2014-11-18

    Purpose in life has been linked with better health (mental and physical) and health behaviors, but its link with patterns of health care use are understudied. We hypothesized that people with higher purpose would be more proactive in taking care of their health, as indicated by a higher likelihood of using preventive health care services. We also hypothesized that people with higher purpose would spend fewer nights in the hospital. Participants (n = 7,168) were drawn from the Health and Retirement Study, a nationally representative panel study of American adults over the age of 50, and tracked for 6 y. After adjusting for sociodemographic factors, each unit increase in purpose (on a six-point scale) was associated with a higher likelihood that people would obtain a cholesterol test [odds ratio (OR) = 1.18, 95% confidence interval (CI) = 1.08-1.29] or colonoscopy (OR = 1.06, 95% CI = 0.99-1.14). Furthermore, females were more likely to receive a mammogram/X-ray (OR = 1.27, 95% CI = 1.16-1.39) or pap smear (OR = 1.16, 95% CI = 1.06-1.28), and males were more likely to receive a prostate examination (OR = 1.31, 95% CI = 1.18-1.45). Each unit increase in purpose was also associated with 17% fewer nights spent in the hospital (rate ratio = 0.83, 95% CI = 0.77-0.89). An increasing number of randomized controlled trials show that purpose in life can be raised. Therefore, with additional research, findings from this study may inform the development of new strategies that increase the use of preventive health care services, offset the burden of rising health care costs, and enhance the quality of life among people moving into the ranks of our aging society.

    Purpose in life has been linked with better health (mental and physical) and health behaviors, but its link with patterns of health care use are understudied. We hypothesized that people with higher purpose would be more proactive in taking care of their health, as indicated by a higher likelihood of using preventive health care services. We also hypothesized that people with higher purpose would spend fewer nights in the hospital.

    In this analysis of racial confounds in the study of homelessness and self-actualization, 100 black and 71 white homeless men from a mission and a street environment were compared to test the hypothesis that the prototypes of black and white homeless men are different. Discriminant analysis of items from the Short Index of Self-actualization of Jones and Crandall, willingness to use services, history of homelessness, and self-reported health ratings correctly classified 83.6% of black and white homeless men (Wilks' lambda = .46, p < .0001). The prototypic black homeless person and the prototypic white homeless person have strong differences so race must be evaluated in studies of such groups. PMID:8332670

    The mechanical properties of an elastomer, including rupture and its time dependence, are defined uniquely by a tensile property surface in normalized stress-strain-time coordinates. In practice, the property surface is determined from short-time constant strain-rate uniaxial tests. By using the time reduction properties of both temperature and cross-link density, an effective time scale of over ten decades of log time can be covered. Changes in cross-link density, filler content, or swelling do not affect the limits of the property surface when plotted in logarithmic coordinates but merely shift their positions. The shape, however, may be modified in certain cases. The service life of an elastomer in the absence of aging reactions can be estimated from the property surface and expected in-use conditions such as strains (static or dynamic).

    Space Station Freedom is being developed for a service life of up to thirty years. As a consequence, the design requirements for the seals to be used are unprecedented. Full scale testing to assure the selected seals can satisfy the design requirements are not feasible. As an alternative, a sub-scale test program has been developed by MSFC to calibrate the analysis tools to be used to certify the proposed design. This research has been conducted in support of the MSFC Integrated Seal Test Program. The ultimate objective of this research is to correlate analysis and test results to qualify the analytical tools, which in turn, are to be used to qualify the flight hardware. This research is totally focused on O-rings that are compressed by perpendicular clamping forces. In this type of seal the O-ring is clamped between the sealing surfaces by loads perpendicular to the circular cross section.

    Two series of antihail rocket propellant grains failed only 3 months after production, due to the appearance of cracks in the grain channel. Structural integrity analysis demonstrated sufficient reliability at the beginning of service life. Further analysis showed that under temperature loads, cumulative damage during the short period in field stocks caused the grain failure, despite the established opinion that such failure can become significant only after lengthy storage. A linear cumulative damage law is evaluated by exposing a number of hydroxyl-terminated polybutadiene (HTPB) composite propellant specimens to different but constant stress levels. The analysis showed that cumulative damage must not be overlooked at the design stage. Further, a positive correlation between the propellant cumulative damage law and tensile strength is strongly indicated.

    A new second-order theory was developed for predicting the service lives of aerospace structural components. The predictions based on this new theory were compared with those based on the Ko first-order theory and the classical theory of service life predictions. The new theory gives very accurate service life predictions. An equivalent constant-amplitude stress cycle method was proposed for representing the random load spectrum for crack growth calculations. This method predicts the most conservative service life. The proposed use of minimum detectable crack size, instead of proof load established crack size as an initial crack size for crack growth calculations, could give a more realistic service life.

Seals are simple devices, in wide spread use. The most common type of seal is the O-ring. O-ring seals are typically rings of rubber with a circular cross section. The rings are placed between the surfaces to be sealed, usually in a groove of some design. The particular design may differ based on a number of different factors. This research is focused on O-rings that are staticly compressed by perpendicular clamping forces, commonly referred to as face seals.

  14. Life as an acoustician in industry, academia, and government service

    2001-05-01

    Acoustics is a science that has very broad applications, which affect all different areas of our lives. During the last 20 years, I have combined family with a career as an acoustics engineer in industry, a tenured faculty member at a university and, most recently, a program manager in a government agency. In these positions I have worked in several areas of acoustics, including noise control, structural acoustics, building acoustics, sound quality, physical acoustics, acoustic materials, underwater acoustics, biomedical ultrasound, physiological acoustics, and bioacoustics. Although the fundamental science of sound is the foundation of all these areas, communication of ideas, problems, and solutions varies greatly from industry to academia to government. Thus knowing the science and how to use it are not enough, as communication skills and the ability to adapt them to changing environments are essential for a successful career. In addition to describing life as an acoustician in industry, academia, and government service, I will present several examples of how even though the acoustic fundamentals are the same, how they are communicated could become a disaster or save the day.

    Purpose: Use of oncology-related services is increasingly scrutinized, yet precisely which services are actually rendered to patients, particularly at the end of life, is unknown. This study characterizes the end-of-life use of medical services by patients with gynecologic cancer at a safety-net hospital. Methods: Oncologic history and metrics of medical use (eg, hospitalizations, chemotherapy infusions, procedures) for patients with gynecologic oncology who died between December 2006 and February 2012 were evaluated. Mixed-effect regression models were used to test time effects and construct usage summaries. Results: Among 116 subjects, cervical cancer accounted for the most deaths (42%). The median age at diagnosis was 55 years; 63% were Hispanic, and 65% had advanced disease. Only 34% died in hospice care. The median times from do not resuscitate/do not intubate documentation and from last therapeutic intervention to death were 9 days and 55 days, respectively. Significant time effects for all services (eg, hospitalizations, diagnostics, procedures, treatments, clinic appointments) were detected during the patient's final year (P < .001), with the most dramatic changes occurring during the last 2 months. Patients with longer duration of continuity of care used significantly fewer resources toward the end of life. Conclusion: To our knowledge, this is the first report enumerating medical services obtained by patients with gynecologic cancer in a large, public hospital during the end of life. Marked changes in interventions in the patient's final 2 months highlight the need for cost-effective, evidence-based metrics for delivering cancer care. Our data emphasize continuity of care as a significant determinant of oncologic resource use during this critical period. PMID:25604595

  1. A service life extension (SLEP) approach to operating aging aircraft beyond their original design lives

    NASA Astrophysics Data System (ADS)

    Pentz, Alan Carter

    With today's uncertain funding climate (including sequestration and continuing budget resolutions), decision makers face severe budgetary challenges to maintain dominance through all aspects of the Department of Defense (DoD). To meet war-fighting capabilities, the DoD continues to extend aircraft programs beyond their design service lives by up to ten years, and occasionally much more. The budget requires a new approach to traditional extension strategies (i.e., reuse, reset, and reclamation) for structural hardware. While extending service life without careful controls can present a safety concern, future operations planning does not consider how much risk is present when operating within sound structural principles. Traditional structural hardware extension methods drive increased costs. Decision makers often overlook the inherent damage tolerance and fatigue capability of structural components and rely on simple time- and flight-based cycle accumulation when determining aircraft retirement lives. This study demonstrates that decision makers should consider risk in addition to the current extension strategies. Through an evaluation of eight military aircraft programs and the application and simulation of F-18 turbine engine usage data, this dissertation shows that insight into actual aircraft mission data, consideration of fatigue capability, and service extension length are key factors to consider. Aircraft structural components, as well as many critical safety components and system designs, have a predefined level of conservatism and inherent damage tolerance. The methods applied in this study would apply to extensions of other critical structures such as bridges. Understanding how much damage tolerance is built into the design compared to the original design usage requirements presents the opportunity to manage systems based on risk. The study presents the sensitivity of these factors and recommends avenues for further research.

    Sajjadi, Homeira; Vameghi, Meroe; Ghazinour, Mehdi; KhodaeiArdakani, Mohammadreza

    2013-01-01

    Objective: Caregivers of cancer patients are exposed to different types of psychosocial stress which influence their quality of life. The purposes of this study were to assess quality of life in caregivers of children with cancer and to investigate the relationship between the caregivers’ quality of life and quality of services in the social work section. Method: 125 caregivers were recruited. Quality of life was measured by the Iranian version of the WHOQOL-BREF questionnaire and data concerning service quality were obtained from the Iranian version of the SERVQUAL questionnaire. Findings: Scores in physical health, psychological status and environmental conditions for caregivers of children with cancer were significantly lower than the general population. There was a negative correlation between the tangible domain of SERVQUAL and the psychological status and environmental conditions of quality of life. The tangible dimension was the only aspect of service quality to predict caregivers’ quality of life regarding psychological status and environmental conditions. Conclusion: Caregivers of children with a disease are care consumers and, like all consumers, they expect good service. Delivering high quality services consistently is difficult but profitable for a service organization. In other words, trying to deliver more appropriate services than patients expect to receive from their social work care is one of the most reliable ways to promote caregivers’ satisfaction and quality of life.

    2015-01-01

    The paper presents the results of an end-of-service-life study on 2 kinds of protective gloves designed for workplaces in which workers are exposed to mineral oils and mechanical factors. The authors developed their own end-of-service-life study method that takes into account factors occurring during real-life use of protective gloves. The examined gloves were subjected to mechanical, chemical, and physical factors. The objective of the study was to compare the protective in new gloves subjected to a laboratory simulation test and in gloves used at workplaces in car repair shops. A further goal was to design a glove assessment procedure that would ensure comprehensive analysis of the actual level of performance provided by gloves exposed to selected chemical and mechanical factors as well as subjected to the influence of temperature and humidity, mechanical damage, and chemical degradation of material. The results lead to the conclusion that simultaneous exposure of protective gloves to mechanical, chemical, and physical factors significantly decreases their performance levels. Furthermore, similar performance levels were obtained for gloves subjected to laboratory simulation tests and for those used in the workplace. PMID:24965322

    The International Space Station (ISS) Water Processor Assembly (WPA) and Oxygen Generation Assembly (OGA) manage and process water at various levels of cleanliness for multiple purposes. The effluent of theWPA and the influent of the OGA require water at very high levels of purity. The bulk of the water purification that occurs in both systems is performed by consumable activated carbon and ion exchange resin beds. Replacement beds must be available on orbit in order to continue the ISS critical processes of water purification and oxygen generation. Various hurdles exist in order to ensure viable spare resin beds. These include the characteristics of resin beds such as: storage environment, shelf life requirements, microbial growth, and variations in the levels and species of contaminants the beds are required to remove. Careful consideration has been given to match water models, bed capacities and spares traffic models to ensure that spares are always viable. The results of these studies and considerations, in particular, how shelf life requirements affect resin bed life management, are documented in this paper.

    This article presents findings of a study that explored the relationship between purpose in life and African American adolescents' use of prenatal care services. The findings revealed no statistically significant relationship, thus suggesting that purpose in life may not be a crucial factor in determining whether African American adolescents use prenatal care services. The need to explore the influence of other variables on service use and the importance of considering such findings for appropriate health care and social work intervention are discussed.

    2011-06-01

    An energy based fatigue life prediction framework has been developed for calculation of remaining fatigue life of in service gas turbine materials. The purpose of the life prediction framework is to account aging effect caused by cyclic loadings on fatigue strength of gas turbine engines structural components which are usually designed for very long life. Previous studies indicate the total strain energy dissipated during a monotonic fracture process and a cyclic process is a material property that can be determined by measuring the area underneath the monotonic true stress-strain curve and the sum of the area within each hysteresis loop in the cyclic process, respectively. The energy-based fatigue life prediction framework consists of the following entities: (1) development of a testing procedure to achieve plastic energy dissipation per life cycle and (2) incorporation of an energy-based fatigue life calculation scheme to determine the remaining fatigue life of in-service gas turbine materials. The accuracy of the remaining fatigue life prediction method was verified by comparison between model approximation and experimental results of Aluminum 6061-T6. The comparison shows promising agreement, thus validating the capability of the framework to produce accurate fatigue life prediction.

    The high rate of mental health problems in HIV-infected women jeopardizes the health of this vulnerable population, and constitutes a mandate for integrating mental health services into HIV primary care. The Whole Life project-a collaboration of the departments of Psychiatry and Obstetrics/Gynecology at the University of Miami School of Medicine-successfully integrated mental health services into primary HIV care for women. This article describes the conceptual framework of the integration, implementation strategies, effects of the service integration, and lessons learned. Funded by the Health Resources and Services Administration (HRSA) as a Special Program of National Significance (SPNS), Whole Life efforts have been sustained beyond the demonstration funding period as a result of the changes brought about in organizational structures, service delivery, and the providers' conceptualization of health for HIV-infected women.

    2014-01-01

    One of the critical non-replaceable systems of a long-term manned orbital station is the propulsion system. Since the propulsion system operates beginning with the launch of station elements into orbit, its service life determines the service life of the station overall. Weighing almost a million pounds, the International Space Station (ISS) is about four times as large as the Russian space station Mir and about five times as large as the U.S. Skylab. Constructed over a span of more than a decade with the help of over 100 space flights, elements and modules of the ISS provide more research space than any spacecraft ever built. Originally envisaged for a service life of fifteen years, this Earth orbiting laboratory has been in orbit since 1998. Some elements that have been launched later in the assembly sequence were not yet built when the first elements were placed in orbit. Hence, some of the early modules that were launched at the inception of the program were already nearing the end of their design life when the ISS was finally ready and operational. To maximize the return on global investments on ISS, it is essential for the valuable research on ISS to continue as long as the station can be sustained safely in orbit. This paper describes the work performed to extend the service life of the ISS propulsion system. A system comprises of many components with varying failure rates. Reliability of a system is the probability that it will perform its intended function under encountered operating conditions, for a specified period of time. As we are interested in finding out how reliable a system would be in the future, reliability expressed as a function of time provides valuable insight. In a hypothetical bathtub shaped failure rate curve, the failure rate, defined as the number of failures per unit time that a currently healthy component will suffer in a given future time interval, decreases during infant-mortality period, stays nearly constant during the service

    2000-08-24

    RPP-6153, Engineering Task Plan for Hose-in-Hose Transfer System for the Interim Stabilization Program, defines the programmatic goals, functional requirements, and technical criteria for the development and subsequent installation of transfer line equipment to support Hanford's Interim Stabilization Program. RPP-6028, Specification for Hose in Hose Transfer Lines for Hanford's Interim Stabilization Program, has been issued to define the specific requirements for the design, manufacture, and verification of transfer line assemblies for specific waste transfer applications. Included in RPP-6028 are tables defining the chemical constituents of concern to which transfer lines will be exposed. Current Interim Stabilization Program planning forecasts that the at-grade transfer lines will be required to convey pumpable waste for as much as three years after commissioning. Prudent engineering dictates that the equipment placed in service have a working life in excess of this forecasted time period, with some margin to allow for future adjustments to the planned schedule. This document evaluates the effective service life of the Hose-in-Hose Transfer Lines, based on information submitted by the manufacturer and published literature. The effective service life of transfer line assemblies is a function of several factors. Foremost among these are process fluid characteristics, ambient environmental conditions, and the manufacturer's stated shelf life. This evaluation examines the manufacturer's certification of shelf life, the manufacturer's certifications of chemical compatibility with waste, and published literature on the effects of exposure to ionizing radiation on the mechanical properties of elastomeric materials to evaluate transfer line service life.

  13. Accounting for ecosystem services in life cycle assessment, Part I: a critical review.

    PubMed

    Zhang, Yi; Singh, Shweta; Bakshi, Bhavik R

    2010-04-01

    If life cycle oriented methods are to encourage sustainable development, they must account for the role of ecosystem goods and services, since these form the basis of planetary activities and human well-being. This article reviews methods that are relevant to accounting for the role of nature and that could be integrated into life cycle oriented approaches. These include methods developed by ecologists for quantifying ecosystem services, by ecological economists for monetary valuation, and life cycle methods such as conventional life cycle assessment, thermodynamic methods for resource accounting such as exergy and emergy analysis, variations of the ecological footprint approach, and human appropriation of net primary productivity. Each approach has its strengths: economic methods are able to quantify the value of cultural services; LCA considers emissions and assesses their impact; emergy accounts for supporting services in terms of cumulative exergy; and ecological footprint is intuitively appealing and considers biocapacity. However, no method is able to consider all the ecosystem services, often due to the desire to aggregate all resources in terms of a single unit. This review shows that comprehensive accounting for ecosystem services in LCA requires greater integration among existing methods, hierarchical schemes for interpreting results via multiple levels of aggregation, and greater understanding of the role of ecosystems in supporting human activities. These present many research opportunities that must be addressed to meet the challenges of sustainability. PMID:20178382

    1989-10-01

    This paper describes methods and materials used to extend the useful life ot extruded polyethylene insulated cables rated 15KV that have developed electrochemical trees in the insulation of sufficient severity to cause service failures. Earlier rehabilitation methods treated extruded dielectric cable with both gases and insulating liquids. This new method fills the cable and impregnates the insulation with a silicone liquid. This liquid, which is reactive, significantly improves the voltage breakdown strength of the cables, which has been reduced by electrochemical trees, and extends the useful service life of the cable. A review of the criteria used to develop the silicone liquid for this application and the methodology used to inject it into the cable will be discussed. An assessment of the costs of this life extension indicates a significantly lower cost than conventional cable replacement with little disturbance to the service and property of the customer.

    The results of a life evaluation program on rigid explosive transfer lines, which are used to initiate aircraft emergency crew escape functions, are presented in order to provide quantitative information on rigid explosive transfer lines which can contribute to responsible, conservative, service life determinations. The program involved the development of a test methodology, testing of the three types of transfer lines in use in the U.S., testing of these lines following a repeat of the thermal test conducted in the original qualification, and conducting a degradation investigation. Results from the testing of more than 800 components showed that rigid explosive transfer lines were not affected by age, service, or a repeat of the thermal qualification tests on full-service lines. The explosive degradation limits were approximated and the mechanisms examined. It is concluded that the service lives of rigid explosive transfer lines should be considered for extension in order to provide cost savings and increased system reliability.

    Objective: To assess service-satisfaction and quality of life among patients with schizophrenia in a tertiary psychiatric healthcare facility in Lagos, Nigeria. Methods: Cross-sectional survey of 101 (out of 120) patients diagnosed with schizophrenia attending the outpatient clinic of the Federal Neuro-Psychiatric Hospital Yaba, Lagos, Nigeria. The Structured Clinical Interview for DSM-IV diagnosis (SCID), Charleston Psychiatric Out-patient Scale (CPOSS), and the World-Health Organisation Quality of Life –Bref scale (WHOQOL-BREF) was used in assessing diagnosis, patient satisfaction and subjective quality of life respectively. Results: The ages of the patient ranged from 19-81. Males (49.5%) and females (50.5%) had almost equal distribution. Mean duration of attendance was 8.7years ± 8.50. Service satisfaction ranged between 25-60 on the CPOSS. Areas that had higher mean scores on CPOSS were with items (1) Helpfulness of the records clerk (3.70±1.1), (7) Helpfulness of services received (3.69±1.0). Subjective quality of life was high (3.65±1.8), satisfaction with health was also high (3.40±1.1). Service satisfaction correlated with Quality of life at P < 0.00. PMID:27114651

Aim This paper is a report of an exploration of older people’s experiences of substance use in the context of ageing, and its impact on health, quality of life, relationships and service use. Background Use of illicit drugs by older people is a neglected policy, research and service provision and is generally perceived as a lifestyle of younger populations. Method A convenience sample of 11 people aged 49–61 years (mean 57 years) in contact with voluntary sector drug treatment services participated in qualitative semi-structured tape-recorded interviews and thematic content analysis was performed. The data were collected in 2008. Findings Drug use can have negative impacts on health status, quality of life, family relationships and social networks that accrue with age. Participants were identified as early or later onset users of drugs due to the impact of life events and relationships. A range of substances had been used currently and throughout their lives, with no single gateway drug identified as a prelude to personal drug careers. Life review and reflection were common, in keeping with ageing populations, along with regret of ever having started to use drugs. Living alone and their accommodation made them more susceptible to social isolation, and they reported experiences of death and dying of their contemporaries and family members earlier than usual in the life course. Conclusion Older people who continue to use drugs and require the support of services for treatment and care are an important emerging population and their specific needs should recognized.

  18. Fatigue life prediction under service load considering strengthening effect of loads below fatigue limit

    Zhao, Lihui; Zheng, Songlin; Feng, Jinzhi

    2014-11-01

    Lightweight design requires an accurate life prediction for structures and components under service loading histories. However, predicted life with the existing methods seems too conservative in some cases, leading to a heavy structure. Because these methods are established on the basis that load cycles would only cause fatigue damage, ignore the strengthening effect of loads. Based on Palmgren-Miner Rule (PMR), this paper introduces a new method for fatigue life prediction under service loadings by taking into account the strengthening effect of loads below the fatigue limit. In this method, the service loadings are classified into three categories: damaging load, strengthening load and none-effect load, and the process for fatigue life prediction is divided into two stages: stage I and stage II, according to the best strengthening number of cycles. During stage I, fatigue damage is calculated considering both the strengthening and damaging effect of load cycles. While during stage II, only the damaging effect is considered. To validate this method, fatigue lives of automobile half shaft and torsion beam rear axle are calculated based on the new method and traditional methods, such as PMR and Modified Miner Rule (MMR), and fatigue tests of the two components are conducted under service loading histories. The tests results show that the percentage errors of the predicted life with the new method to mean life of tests for the two components are -3.78% and -1.76% separately, much lesser than that with PMR and MMR. By considering the strengthening effect of loads below the fatigue limit, the new method can significantly improve the accuracy for fatigue life prediction. Thus lightweight design can be fully realized in the design stage.

    The Satellite Base Augmentation System (SBAS) - EGNOS (European Geostationary Navigation Overlay Service) has been certified for Safety of Life (SoL) service for aircraft navigation since 2nd of March 2011. Unfortunately for the territory of Poland, located at the edge of EGNOS service area, the quality of the service corrections are still not sufficient for aircraft navigation requirements. Years 2012 and 2013 are forecasted as a maximum of solar activity in a 11-year solar cycle. This time period will be the chance to perform the first tests for the EGNOS Safety of Life service quality in disturbed ionospheric conditions. During the previous maximum of solar activity, the storm on 30 October 2003 resulted in the inability to use WAAS corrections for more than 12 hours. This was caused by a very large gradient of disturbances and its' very sharp boundaries - vertical TEC (VTEC) varied from ~ 40 to ~ 120 TECU (TEC units) within an hour (over ~ 150 km distance). These circumstances gave the opportunity to carry out the test flights to examine the navigation parameters obtained for EGNOS SoL service in disturbed ionospheric conditions. The paper presents project proposal of study and analyses of such fundamental navigation parameters as: accuracy of determined position, availability, continuity and integrity, determined for selected disturbances in relation to quiet conditions. It can give a possibility to estimate of the quality of EGNOS SoL service in Polish airspace during the different phases of flight and its resistance to critical ionospheric conditions.

    2008-11-25

    A method and computer-based apparatus for monitoring the degradation of, predicting the remaining service life of, and/or planning maintenance for, an operating system are disclosed. Diagnostic information on degradation of the operating system is obtained through measurement of one or more performance characteristics by one or more sensors onboard and/or proximate the operating system. Though not required, it is preferred that the sensor data are validated to improve the accuracy and reliability of the service life predictions. The condition or degree of degradation of the operating system is presented to a user by way of one or more calculated, numeric degradation figures of merit that are trended against one or more independent variables using one or more mathematical techniques. Furthermore, more than one trendline and uncertainty interval may be generated for a given degradation figure of merit/independent variable data set. The trendline(s) and uncertainty interval(s) are subsequently compared to one or more degradation figure of merit thresholds to predict the remaining service life of the operating system. The present invention enables multiple mathematical approaches in determining which trendline(s) to use to provide the best estimate of the remaining service life.

    Global cloud frameworks for bioinformatics research databases become huge and heterogeneous; solutions face various diametric challenges comprising cross-integration, retrieval, security and openness. To address this, as of March 2011 organizations including RIKEN published 192 mammalian, plant and protein life sciences databases having 8.2 million data records, integrated as Linked Open or Private Data (LOD/LPD) using SciNetS.org, the Scientists' Networking System. The huge quantity of linked data this database integration framework covers is based on the Semantic Web, where researchers collaborate by managing metadata across public and private databases in a secured data space. This outstripped the data query capacity of existing interface tools like SPARQL. Actual research also requires specialized tools for data analysis using raw original data. To solve these challenges, in December 2009 we developed the lightweight Semantic-JSON interface to access each fragment of linked and raw life sciences data securely under the control of programming languages popularly used by bioinformaticians such as Perl and Ruby. Researchers successfully used the interface across 28 million semantic relationships for biological applications including genome design, sequence processing, inference over phenotype databases, full-text search indexing and human-readable contents like ontology and LOD tree viewers.

Therefore, an advanced aircraft service life monitoring method based on flight-by-flight load spectra is proposed and recommended for IAT program to track consumed fatigue life as an alternative to the current method which is based on the crack severity index (CSI) value. Damage Tolerance is one of aircraft design philosophies to ensure that aging aircrafts satisfy structural reliability in terms of fatigue failures throughout their service periods. IAT program, one of the most important tasks of DTA, is able to track potential structural crack growth at critical areas in the major airframe structural components of individual aircraft. The F-16C/D aircraft is equipped with a flight data recorder to monitor flight usage and provide the data to support structural load analysis. However, limited memory of flight data recorder allows user to monitor individual aircraft fatigue usage in terms of only the vertical inertia (NzW) data for calculating Crack Severity Index (CSI) value which defines the relative maneuver severity. Current IAT method for the F-16C/D Block 32 based on CSI value calculated from NzW is shown to be not accurate enough to monitor individual aircraft fatigue usage due to several problems. The proposed advanced aircraft service life monitoring method based on flight-by-flight load spectra is recommended as an improved method for the F-16C/D Block 32 aircraft. Flight-by-flight load spectra was generated from downloaded Crash Survival Flight Data Recorder (CSFDR) data by calculating loads for each time hack in selected flight data utilizing loads equations.

    Homeless persons tend to die younger than the housed population and have complex, often unmet, end-of-life care needs. High levels of illicit drug use among this population are a particular challenge for health and social services professionals involved in end-of-life care services delivery. This article explores the challenges of end-of-life care services to homeless illicit drug users based on data collected during a national study on end-of-life care services delivery to homeless persons in Canada. The authors conducted qualitative interviews with 50 health and social services professionals involved in health services delivery to homeless persons in five cities. Interviews were transcribed verbatim and analysed thematically. Themes were organised into two domains. First, barriers preventing homeless illicit drug users from accessing end-of-life care services, such as competing priorities (e.g. withdrawal management), lack of trust in healthcare providers and discrimination. Second, challenges to end-of-life care services delivery to this population in health and social care settings, including non-disclosure of illicit drug use, pain and symptom management, interruptions in care, and lack of experience with addictions. The authors identify a need for increased research on the role of harm reduction in end-of-life care settings to address these challenges.

    RPP-6153, Engineering Task Plan for Hose-in-Hose Transfer System for the Interim Stabilization Program (Torres, 2000a), defines the programmatic goals, functional requirements, and technical criteria for the development and subsequent installation of waste transfer line equipment to support Hanford's Interim Stabilization Program. RPP-6028, Specification for Hose in Hose Transfer Lines for Hanford's Interim Stabilization Program (Torres, 2000b), has been issued to define the specific requirements for the design, manufacture, and verification of transfer line assemblies for specific waste transfer applications associated with Interim Stabilization. Included in RPP-6028 are tables defining the chemical constituents of concern to which transfer lines will be exposed. Current Interim Stabilization Program planning forecasts that the at-grade transfer lines will be required to convey pumpable waste for as much as three years after commissioning, RPP-6028 Section 3.2.7. Performance Incentive Number ORP-05 requires that all the Single Shell Tanks be Interim Stabilized by September 30, 2003. The Tri-Party Agreement (TPA) milestone M-41-00, enforced by a federal consent decree, requires all the Single Shell Tanks to be Interim stabilized by September 30, 2004. By meeting the Performance Incentive the TPA milestone is met. Prudent engineering dictates that the equipment used to transfer waste have a life in excess of the forecasted operational time period, with some margin to allow for future adjustments to the planned schedule. This document evaluates the effective service life of the Hose-in-Hose Transfer Lines, based on information submitted by the manufacturer, published literature and calculations. The effective service life of transfer line assemblies is a function of several factors. Foremost among these are the hose material's resistance to the harmful effects of process fluid characteristics, ambient environmental conditions, exposure to ionizing radiation and the

    Background. Acute psychiatric provision in the UK today as well as globally has many critics including service users and nurses. Method. Four focus groups, each meeting twice, were held separately for service users and nurses. The analysis was not purely inductive but driven by concerns with the social position of marginalised groups - both patients and staff. Results. The main themes were nurse/patient interaction and coercion. Service users and nurses conceptualised these differently. Service users found nurses inaccessible and uncaring, whereas nurses also felt powerless because their working life was dominated by administration. Nurses saw coercive situations as a reasonable response to factors 'internal' to the patient whereas for service users they were driven to extreme behaviour by the environment of the ward and coercive interventions were unnecessary and heavy handed. Conclusion. This study sheds new light on living and working in acute mental health settings today by comparing the perceptions of service users and nurses and deploying service user and nurse researchers. The intention is to promote better practice by providing a window on the perceptions of both groups. PMID:24330951

    The service life of zinc rich primers on carbon steel can be estimated by immersing a primer coated glass slide into an aqueous copper sulfate solution and measuring the amount of zinc that reacts with the copper in 15 minutes. This zinc availability test was used to evaluate eleven primers currently available for which marine beach exposure data was available from previous programs. Results were evaluated and a correlation between zinc availability and ASTM rust grade was shown.

    Planetary-gear transmissions are compact speed reductions which use parallel-load paths to transmit high power. The range of possible reduction ratios is bounded from below and above by limits on the relative size of the planet gears. For a single-plane planetary transmission, the speed-reduction ratio must be greater than two for planet gears to exist. As the ratio increases, so does the size of the planets relative to the sizes of the sun and ring. Which ratio is best for a planetary reduction can be resolved by studying a series of optimal designs. In this series, each design is obtained by maximizing the service life for a spur-gear planetary with a fixed size, speed-reduction ratio, input speed, power and materials. The planetary-gear reduction service life is modeled as a function of the two-parameter Weibull distributed service lives of the ball bearings and spur gears in the reduction. Planet-bearing life strongly influences the optimal reduction lives which point to an optimal planetary reduction ratio in the neighborhood of four to five.

    The service life of the Hungarian Paks Nuclear Power Plant (NPP) will be extended from the originally planned 30 years to 50 years. To improve the reliability of the results obtained in frame of the old reactor pressure vessel (RPV) surveillance programme, new methods have been developed, and based on them, the old exposition data have been re-evaluated for all the four reactor units. At the same time, a new RPV surveillance programme has been developed and introduced, and long term irradiations have been performed to determine the radiation damage of the surveillance specimens due to the high fast neutron exposition. Neutron transport calculations have been performed with a validated neutron transport code system to determine the fast neutron exposition of the RPVs during the extended service life. The cavity dosimetry is in the introductory phase. This paper presents the new developments in the field of the RPV surveillance dosimetry and summarises the results obtained. According to the results the service life of the NPP can safely be extended for the planned 50 years.

    2008-07-01

    Orbital Satellite Services Limited (OSSL) is a satellite servicing company that is developing an orbit life extension vehicle (OLEV) to extend the operational lifetime of geostationary satellites. The industrial consortium of SSC (Sweden), Kayser-Threde (Germany) and Sener (Spain) is in charge to develop and industrialize the space and ground segment. It is a fully commercial program with support of several space agencies during the development phase. The business plan is based on life extension for high value commercial satellites while also providing the satellite operators with various fleet management services such as graveyard burns, slot transfers and on orbit protection against replacement satellite or launch failures. The OLEV spacecraft will be able to dock with a geostationary satellite and uses an electrical propulsion system to extend its life by taking over the attitude control and station keeping functions. The OLEV system is building on the SMART-1 platform developed by Swedish Space Corporation. It was developed for ESA as a technology test-bed to demonstrate the use of electrical propulsion for interplanetary orbit transfer manoeuvres. The concept is called SMART-OLEV and takes advantage of the low cost, low mass SMART-1 platform by a maximum use of recurrent platform technology.

    Drawing on the ethnographic study of urological cancer services, this article explores how a set of particular discourses embedded in the everyday clinical work in a large teaching hospital in the UK helps materialise particular configurations of cancer and related professional identities. Emerging on the intersection of specific socio-material arrangements (cancer survival rates, treatment regimens, cancer staging classifications, metaphors, clinical specialities) and operating across a number of differential relations (curable/incurable, treatable/untreatable, aggressive/nonaggressive), these configurations help constitute the categories of 'good' and 'bad' cancers as separate and contrasting entities. These categories help materialise particular distributions of power and are thus implicated in the making of specific claims about the identity of urological cancer services as unique and privileged. Exploring these issues in view of feminist and material-semiotic approaches to studying science, technology and medicine, this article seeks to move away from the understanding of cancer discourses as primarily linguistic performances, proposing to see them instead as arrangements of practices and relations simultaneously material and semiotic through which particular categories, entities and phenomena acquire their determinate nature. In doing so, it seeks to contribute to sociology's broader concern with discursive performativity of cancer. PMID:25847531

  1. The mismatch between patient life expectancy and the service life of implantable devices in current cardioverter-defibrillator therapy: a call for larger device batteries.

    2015-06-01

    In 2005, Bob Hauser published a paper in the Journal of the American College of Cardiology entitled "The growing mismatch between patient longevity and the service life of Implantable Cardioverter-Defibrillators". Now, nearly a decade later, I would like to perform a second look on the problem of a mismatching between ICD device service life and the survival of ICD recipients. Since 2005, the demographics of the ICD population has changed significantly. Primary prevention has become the dominant indication in defibrillator therapy and device implantation is indicated more and more in earlier stages of cardiac diseases. In former larger scale ICD trials, the patient average 5-year survival probability was in a range of 68-71%; in newer CRT-D trials in a range of 72-88%. Due to a progressively widened ICD indication and implantation preferentially performed in patients with better life expectancy, the problem of inadequate device service life is of growing importance. The early days of defibrillator therapy started with a generator volume of 145 ccm and a device service life <18 months. In this early period, the device miniaturization and extension of service life were similar challenges for the technicians. Today, we have reached a formerly unexpected extent of device miniaturization. However, technologic improvements were often preferentially translated in further device miniaturization and not in prolonging device service life. In his analysis, Bob Hauser reported a prolonged device service life of 2.3 years in ICD models with a larger battery capacity of 0.54 up to 0.69 Ah. Between 2008 and 2014, several studies had been published on the problem of ICD longevity in clinical scenarios. These analyses included "older" and currently used single chamber, dual chamber and CRT devices. The reported average 5-year device service life ranged from 0 to 75%. Assuming today technology, larger battery capacities will only result in minimal increase in device volume. Selected

    2015-01-01

    Background Quality of life (QoL) has gained increasing attention as a desired outcome of psychosocial treatments targeting psychotic patients. Yet, the relationship between the patients’ satisfaction with services and QoL has not been clearly established, perhaps due to the multidimensionality of the QoL concept and the variability in its assessment. Aim This is the first systematic meta-analysis of all available evidence assessing the relationship between QoL and service satisfaction. Methods: In all, 19 studies reporting data of 21 independent samples (N = 5,337) were included in the present meta-analysis. In moderator analyses, effects of age, sex, diagnoses (schizophrenia vs. other psychoses), treatment context (inpatients vs. outpatients), study design (cross-sectional vs. longitudinal), and QoL domain (subjective vs. health-related) were examined. Results Analyses revealed a highly significant medium-sized effect (r = .30, p < .001) for the associations of QoL and service satisfaction. Effect sizes were significantly stronger for subjective than health-related quality of life (r = .35 vs. r = .14, respectively). Moreover, associations with subjective QoL remained largely robust when accounting for moderating variables, although there was a trend of stronger associations for outpatients compared to inpatients. In contrast, effect sizes for health-related QoL were small and only observable for samples with longitudinal designs. Conclusion Associations between QoL and service satisfaction appear to be robust but are differentiated in regard to QoL domain. Our findings suggest that agents responsible for service design and implementation need to take the patients’ perception of the service adequacy for achieving QoL enhancement into account.

  5. A simple method to prolong the service life of radioactive sources for external radiotherapy.

    A radioactive source is usually replaced and disposed after being used for a certain amount of time (usually a half-life). In this study, a simple method is proposed to prolong its service life. Instead of replacing the used source with a new source of full activity, a new source of less activity is added in the source holder in front of the used one, so that the total activity of two sources is equal to the initial activity of the used source or even higher. Similarly, more sources can be added to the previous ones. Attenuation of front source(s) to the back source(s) was evaluated with exponential attenuation equation, and variation of source-focus distance (SFD) with inverse square law for Leksell 4C Gamma Knife, which served as an example of external radiotherapy units. When the number of front sources increased from 1 to 3, the relative air kerma decreased from 36.5% to 5.0%. Both the attenuation effect and SFD variation contributed to the decrease in air kerma, with the former being the major factor. If the height of the source can be decreased in some way, such as increasing the specific activity of sources, the sources can be used more efficiently. The method prolongs the service life of sources by several factors, and reduces the expense of source exchange and reclamation. PMID:25207406

    2010-01-01

    Background In order to tackle the deficits in the provision of palliative home care, profound structural changes in the outpatient sector were introduced by law in Germany in 2007. The EPACS study was carried out (Research Accompanying the Establishment of Hospice and Palliative Care Services in Rhineland-Palatinate, Germany) to document the quality of inpatient and outpatient end-of-life care in Rhineland-Palatinate, Germany, before the implementation of these changes. With this article we focus on the study design and methods of the EPACS-Study. We further report first results regarding several aspects of outpatient end-of-life care. Methods The cross-sectional survey was based on a random sample of 5000 inhabitants of Rhineland-Palatinate that had died from May 25 until August 24 of the year 2008. Relatives of these randomly drawn deceased persons were interviewed by means of a written survey. Results The overall response proportion considering only those questionnaires that actually were delivered (n = 3833) was 36.0%. Factors influencing participation were age, sex, and marital status. 355 (25.8%) deceased persons had used professional home care in the four weeks prior to their death, but only very few persons had used a specialised palliative home care service (n = 30; 8.5%). There was a clear gap between the need for specialised outpatient care and the actual utilisation of these services. Conclusions Satisfaction with professional home care was relatively high, but physicians were rated less favourable than nurses. There were deficits especially with respect to physicians' communicative and supportive skills. Further analyses are necessary to provide more detailed information about quality of care in different care settings and for distinct groups. Predictors of good care, as well as obstacles to it, must be further investigated. In the long run, a follow-up survey must be conducted to compare quality of home care before and after the structural changes in

    The service life of aircraft structural components undergoing random stress cycling was analyzed by the application of fracture mechanics. The initial crack sizes at the critical stress points for the fatigue-crack growth analysis were established through proof load tests. The fatigue-crack growth rates for random stress cycles were calculated using the half-cycle method. A new equation was developed for calculating the number of remaining flights for the structural components. The number of remaining flights predicted by the new equation is much lower than that predicted by the conventional equation.

  8. Accounting for ecosystem services in Life Cycle Assessment, Part II: toward an ecologically based LCA.

    2010-04-01

    Despite the essential role of ecosystem goods and services in sustaining all human activities, they are often ignored in engineering decision making, even in methods that are meant to encourage sustainability. For example, conventional Life Cycle Assessment focuses on the impact of emissions and consumption of some resources. While aggregation and interpretation methods are quite advanced for emissions, similar methods for resources have been lagging, and most ignore the role of nature. Such oversight may even result in perverse decisions that encourage reliance on deteriorating ecosystem services. This article presents a step toward including the direct and indirect role of ecosystems in LCA, and a hierarchical scheme to interpret their contribution. The resulting Ecologically Based LCA (Eco-LCA) includes a large number of provisioning, regulating, and supporting ecosystem services as inputs to a life cycle model at the process or economy scale. These resources are represented in diverse physical units and may be compared via their mass, fuel value, industrial cumulative exergy consumption, or ecological cumulative exergy consumption or by normalization with total consumption of each resource or their availability. Such results at a fine scale provide insight about relative resource use and the risk and vulnerability to the loss of specific resources. Aggregate indicators are also defined to obtain indices such as renewability, efficiency, and return on investment. An Eco-LCA model of the 1997 economy is developed and made available via the web (www.resilience.osu.edu/ecolca). An illustrative example comparing paper and plastic cups provides insight into the features of the proposed approach. The need for further work in bridging the gap between knowledge about ecosystem services and their direct and indirect role in supporting human activities is discussed as an important area for future work.

  9. Form and Actuality

    NASA Astrophysics Data System (ADS)

    Bitbol, Michel

    A basic choice underlies physics. It consists of banishing actual situations from theoretical descriptions, in order to reach a universal formal construct. Actualities are then thought of as mere local appearances of a transcendent reality supposedly described by the formal construct. Despite its impressive success, this method has left major loopholes in the foundations of science. In this paper, I document two of these loopholes. One is the problem of time asymmetry in statistical thermodynamics, and the other is the measurement problem of quantum mechanics. Then, adopting a broader philosophical standpoint, I try to turn the whole picture upside down. Here, full priority is given to actuality (construed as a mode of the immanent reality self-reflectively being itself) over formal constructs. The characteristic aporias of this variety of "Copernican revolution" are discussed.

    Data obtained from testing shipping package materials have been leveraged to support extending the service life of select shipping packages while in nuclear materials transportation. Increasingly, nuclear material inventories are being transferred to an interim storage location where they will reside for extended periods of time. Use of a shipping package to store nuclear materials in an interim storage location has become more attractive for a variety of reasons. Shipping packages are robust and have a qualified pedigree for their performance in normal operation and accident conditions within the approved shipment period and storing nuclear material within a shipping package results in reduced operations for the storage facility. However, the shipping package materials of construction must maintain a level of integrity as specified by the safety basis of the storage facility through the duration of the storage period, which is typically well beyond the one year transportation window. Test programs have been established to obtain aging data on materials of construction that are the most sensitive/susceptible to aging in certain shipping package designs. The collective data are being used to support extending the service life of shipping packages in both transportation and storage.

    This paper addresses the problem of the development of a lining wearing uniformly in service, providing a long service life, and promoting the occurrence of autogeneous processes. The lining design developed is proposed for use in the furnaces for melting in a molten bath at a copper melting plant. The refractories investigated were MP dense periclase, MPM fused periclase-based magnesite, KhM chrome-magnesite, PKhS periclase-chromite roof, PShS periclase-spinellide, PKhPP fused periclase-chromite-base periclase-chromite, KhPT heat resistant chromite-periclase, VG high alumina, and ShM chamotte. The properties of the refractories are presented. It was established that the periclase-chromite refractories produced from fused material show the greatest life in the lining of furnaces for melting in a molten bath. A method of production of fused chromite-periclase was developed and a designed combined lining of a furnace with the use of highly resistanct refractories was presented.

    The purpose of the current investigation was to assess interest in mental health services among parents of adolescent solid organ transplant recipients and the relationship between parent perceived need for mental health services and patient health-related quality of life (HRQOL). Sixty-three parents rated interest in receiving 10 mental health services, and patient HRQOL ratings were gathered from adolescent transplant recipients and their parents. Ninety-four percent of parents expressed some level of interest in at least one of the proposed services, with over 40 % indicating maximum interest. Parents' perceived need for mental health services was inversely related to adolescent and parent reports of HRQOL on the behavior, mental health, family cohesion, and parental impact-emotional domains. Results suggest that parents of adolescent solid organ transplant recipients are interested in receiving mental health services for their families. Assessment of need for mental health services and HRQOL may inform the medical team of families requiring intervention.

    HBS and HPS versions using single-crystal tungsten or molybden alloys as a cladding of heat pipes joined outside the core of reactor with thermionic converters are considered. Solid solutions of uranium and tantalum carbides, uranium-zirconium carbonitride including cermet type with a matrix made of tungsten are also discussed as the fuels of HBS and HPS. A possibility to rise the heat pipes and thermionic converters service life up to 10 years at the operating temperature up to 1900 K by means of using of single crystal tungsten is shown. Application of carbide fuel ensure possibility to increase operational temperature of the fuel elements and corresponding increase of specific impulse HBS up to 800-850 sec.

    Ultrasonic pulse velocity testing was used to perform non-destructive quality control of refractory plates used as substrates in fast firing of porcelain whitewares. The measurement of the ultrasonic velocity was used to asses the presence of internal voids or cracks originated from the manufacturing procedure. Image analysis was used to predict thermal stability of the refractory materials. Two cordierite-mullite compositions were investigated that are characterized by different microstructure morphologies and crack propagation behaviour. A brief discussion about the correlation between microstructure, crack propagation behaviour and thermal shock resistance is presented. Moreover, empirical models were developed to predict the service life of refractory plates from measured values of ultrasonic velocities in plates in the as-received state.

    Nuclear material inventories are increasingly being transferred to interim storage locations where they may reside for extended periods of time. Use of a shipping package to store nuclear materials after the transfer has become more common for a variety of reasons. Shipping packages are robust and have a qualified pedigree for performance in normal operation and accident conditions but are only certified over an approved transportation window. The continued use of shipping packages to contain nuclear material during interim storage will result in reduced overall costs and reduced exposure to workers. However, the shipping package materials of construction must maintain integrity as specified by the safety basis of the storage facility throughout the storage period, which is typically well beyond the certified transportation window. In many ways, the certification processes required for interim storage of nuclear materials in shipping packages is similar to life extension programs required for dry cask storage systems for commercial nuclear fuels. The storage of spent nuclear fuel in dry cask storage systems is federally-regulated, and over 1500 individual dry casks have been in successful service up to 20 years in the US. The uncertainty in final disposition will likely require extended storage of this fuel well beyond initial license periods and perhaps multiple re-licenses may be needed. Thus, both the shipping packages and the dry cask storage systems require materials integrity assessments and assurance of continued satisfactory materials performance over times not considered in the original evaluation processes. Test programs for the shipping packages have been established to obtain aging data on materials of construction to demonstrate continued system integrity. The collective data may be coupled with similar data for the dry cask storage systems and used to support extending the service life of shipping packages in both transportation and storage.

  18. Using electrochemical protection to prolong service life of scrubbers and associated equipment

    Austenitic chromium-nickel-molybdenum-iron alloys (904L, 316L, 317L, etc.) used to construct Flue Gas Desulfurization (FGD) scrubbers and associated equipment in coal fired generating stations can experience localized corrosion. The problem may be alleviated by using more costly materials such as higher grades of stainless steel or high nickel alloys. An alternative and more cost-effective method of prolonging equipment service life is the use of Papritection{reg_sign}, an electrochemical protection system (EP). Weight-loss coupon results in environments similar to FGD scrubbers have shown that the use of electrochemical protection prolongs the life of stainless steels in oxidizing acid-chloride environments by an average of 3 to 5 times. This paper discusses an EP system that was recently supplied to an electric power utility company to protect a 316L thin metallic lined (wallpapered) FGD scrubber reaction tank. Acidic effluent from the absorber section of the scrubber is piped into this reaction tank for limestone neutralization and hence formation of calcium sulfate. Inspection of the protected reaction tank after one year of operation as well as in-situ coupon test results indicated that the EP system was very effective in mitigating localized corrosion of the scrubber reaction tank. The results are presented in this paper.

    This paper deals with evaluation of creep damage of ~11 years service exposed primary hydrogen reformer tube made of HP-40 grade of steel in a petrochemical industry, which has been carried out in terms of Kachanav's continuum damage mechanics (CDM) model (K-model) and Bogdanoff model (B-model) based on Markov process. Residual life of the tubes was estimated based on hot tensile, conventional creep deformation under identical test conditions, optical microscopy and fractography. Accumulation of damage due to creep has been quantified through microstructural studies. The as received tubes did not reveal any degradation in the material like creep cavitation or voids, but there was indeed loss of tensile strength from room temperature to 870°C for the bottom portion of the tube due to ageing and overheating. Scatter in creep deformation behaviour of the material is probably due to variation in mode of fracture and scatter in voids. From statistical point of view, Weibull distribution pattern for analysing probability of rupture due to void area shifts with increase in true strain towards the higher population of void. The estimation of mean time to reach a specific damage state from K- model and B-model is in close agreement with that of experimental data and can describe the sudden changes of the creep damage in the tertiary region as well. A remnant life of >10 years is estimated at the operating stress-temperature conditions of the top as well as bottom portion of the tube.

    The International Space Station s (ISS) largest crew and cargo resupply vehicle, the Space Shuttle, retired in 2011. To help augment ISS resupply and return capability, NASA announced a project to promote the development of Commercial Orbital Transportation Services (COTS) for the ISS in January of 2006. By December of 2008, NASA entered into space act agreements with SpaceX and Orbital Sciences Corporation for COTS development and ISS Commercial Resupply Services (CRS). The intent of CRS is to fly multiple resupply missions each year to ISS with SpaceX s Dragon vehicle providing resupply and return capabilities and Orbital Science Corporation s Cygnus vehicle providing resupply capability to ISS. The ISS program launched an integration effort to ensure that these new commercial vehicles met the requirements of the ISS vehicle and ISS program needs. The Environmental Control and Life Support System (ECLSS) requirements cover basic cargo vehicle needs including maintaining atmosphere, providing atmosphere circulation, and fire detection and suppression. The ISS-COTS integration effort brought unique challenges combining NASA s established processes and design knowledge with the commercial companies new initiatives and limited experience with human space flight. This paper will discuss the ISS ECLS COTS integration effort including challenges, successes, and lessons learned.

    Background Rigorously applied exercise interventions undertaken in a research setting result in improved health-related quality of life (hrqol) in cancer survivors, but research to demonstrate effective translation of that research to practice is needed. The objective of the present study was to determine the effect of fee-for-service cancer rehabilitation programs in the community on hrqol and on self-reported physical activity and its correlates. Methods After enrolment and 17 ± 4 weeks later, new clients (n = 48) to two fee-for-service cancer rehabilitation programs completed the 36-Item Short Form Health Survey (rand-36: rand Corporation, Santa Monica, CA, U.S.A.), the Godin Leisure-Time Exercise Questionnaire, and questions about physical activity correlates. Normal fee-for-service operations were maintained, including a fitness assessment and individualized exercise programs supervised in a group or one-on-one setting, with no minimum attendance required. Fees were associated with the assessment and with each exercise session. Results Of the 48 participants, 36 (75%) completed both questionnaires. Improvements in the physical functioning, role physical, pain, and energy/fatigue scales on the rand-36 exceeded minimally important differences and were of a magnitude similar to improvements reported in structured, rigorously applied, and free research interventions. Self-reported levels of vigorous-intensity (p = 0.021), but not moderate-intensity (p = 0.831) physical activity increased. The number of perceived barriers to exercise (p = 0.035) and the prevalence of fatigue as a barrier (p = 0.003) decreased. Exercise self-efficacy improved only in participants who attended 11 or more sessions (p = 0.002). Exercise enjoyment did not change (p = 0.629). Conclusions Enrolment in fee-for-service cancer rehabilitation programs results in meaningful improvements in hrqol comparable to those reported by research interventions, among other benefits. The fee-for-service

    With limited resources available, we all would like to allocate health care dollars to do the most good. Clinical research tells us what outcomes to expect (in many cases) from the introduction of a health care program, a test, or a therapy. Even primitive cost analysis can assess the cost of such programs. The ability to place a value on health states is vital when assessing how patient outcomes influence the relative cost-effectiveness of medical procedures, therapies, and programs. Without a means to measure the value of a particular health state, one is left to compare apples with oranges and oranges with vacuum cleaners. In fact, comparisons of fruit and home appliances is relatively easy, because one can readily apply monetary values to apples, oranges, and vacuum cleaners and compare dollar amounts. How can one do the same for the outcomes of medical procedures and diagnostic tests? This is the challenge for health services and outcomes researchers throughout the world and, more urgently, the focus of policy makers, governments, and health insurers. The purpose of this paper is to describe quality-adjusted life-years (QALYs), a method that has successfully measured the outcomes of disparate health programs. We will introduce the QALY method, summarize the various methods of measuring and classifying health states, describe three methods that have been used to measure patients' preferences (utilities) for health states, and discuss the limitations of utility assessment and some controversies that result from the measurement and use of utilities and concerning health-related quality of life. Readers who are interested in general topics of radiology technology assessment and cost-effectiveness analysis should consult other review articles [1-4]. PMID:7484556

    A passive visual end of service life indicator (ESLI) for certain organic vapors has been attached to the inside wall of an organic vapor respirator cartridge. The opposite side of the ESLI touches activated carbon inside the cartridge. During use, organic vapors moving through the cartridge adsorb into both the carbon and the ESLI. The cartridge body is clear so that when vapor concentrations meet a certain threshold, the user may observe the progressive development of an indicator bar down the side of the ESLI. The cartridge is deemed ready to change when any part of the indicator bar touches a marked end line. The performance of the ESLI was observed when the cartridge was tested against a variety of organic vapors, exposure concentrations above the minimum indication level, humidities, temperatures, flow rates, and mixtures. In all cases, the ESLI indicated end of service life with more than 10% cartridge service life remaining (which is a NIOSH test criteria). The results were also compared to mathematical predictions of cartridge service life. PMID:26418577

    2016-02-01

    Most research on military service focuses on its short-term negative consequences, especially the mental and physical injuries of those deployed in warzones. However, studies of long-term outcomes reveal surprisingly positive effects of military service--both those early in adulthood that grow over time and others that can emerge later in life. These multidomain effects have been found in veterans of World War II and the Korean War and are now being seen in veterans of the Vietnam War. Although some are directly attributable to public policies such as the GI Bill, which facilitate educational and economic gains, there are personal developmental gains as well, including autonomy, emotional maturity and resilience, mastery, and leadership skills, that lead to better health and well-being in later life. These long-term effects vary across persons, change over time within persons, and often reflect processes of cumulative advantage and disadvantage. We propose a life-span model of the effects of military service that provides a perspective for probing both long-term positive and negative outcomes for aging veterans. We further explicate the model by focusing on both sociocultural dynamics and individual processes. We identify public-use data that can be examined to evaluate this model, and offer a set of questions that can be used to assess military service. Finally, we outline an agenda for dedicated inquiry into such effects and consider policy implications for the health and well-being of aging veterans in later life. PMID:26655859

    2016-01-01

    Considerable progress has been made in the treatment of late-life depression over the past 20 years, yet considerable gaps in care remain. Gaps in care are particularly pronounced for older men, certain racial and ethnic minority groups, and those with comorbid medical or mental disorders. We reviewed the peer-reviewed literature and conducted interviews with experts in late-life depression to identify promising directions for effectiveness research to address these gaps in care. We searched the PubMed, PsychInfo, and CINHAL databases between January 1, 1998, through August 31, 2013, using terms related to late-life depression and any of the following: epidemiology, services organization, economics of care, underserved groups including health disparities, impact on caregivers, and interventions. The results of this selective review supplemented by more current recommendations from national experts highlight three priority research areas to improve health services for late-life depression: focusing on the unique needs of the patient through patient-centered care and culturally sensitive care, involving caregivers outside the traditional clinical care team, and involving alternate settings of care. We build on these results to offer five recommendations for future effectiveness research that hold considerable potential to advance intervention and health services development for late-life depression.

    1983-02-01

    A laser was constructed in which rhodamine G dissolved in isopropyl alcohol was used as the active medium. It was pumped by a coaxial flashlamp and the output energy of the laser was up to 8 J. An investigation was made of the photochemical stability of rhodamine G solutions as a function of the spectral composition of the pump radiation. Optimal selection of the solvent and of a filter through which the pump radiation was passed, and the use of previously tested components ensured that the service life was superior to that of similar lasers; practically no maintenance was needed during operation. The operating characteristics of the laser and the dynamics of their changes over a period of three years of its use in applications were recorded. When the output energy was approx.5 J per pulse, the laser could emit 1.5 x 10/sup 3/ pulses without dismantling and replacement of the active medium and this represented an integrated irradiance of the active medium in excess of 2 kJ/cm/sup 3/.

  19. Integrated earth system dynamic modeling for life cycle impact assessment of ecosystem services.

    Despite the increasing awareness of our dependence on Ecosystem Services (ES), Life Cycle Impact Assessment (LCIA) does not explicitly and fully assess the damages caused by human activities on ES generation. Recent improvements in LCIA focus on specific cause-effect chains, mainly related to land use changes, leading to Characterization Factors (CFs) at the midpoint assessment level. However, despite the complexity and temporal dynamics of ES, current LCIA approaches consider the environmental mechanisms underneath ES to be independent from each other and devoid of dynamic character, leading to constant CFs whose representativeness is debatable. This paper takes a step forward and is aimed at demonstrating the feasibility of using an integrated earth system dynamic modeling perspective to retrieve time- and scenario-dependent CFs that consider the complex interlinkages between natural processes delivering ES. The GUMBO (Global Unified Metamodel of the Biosphere) model is used to quantify changes in ES production in physical terms - leading to midpoint CFs - and changes in human welfare indicators, which are considered here as endpoint CFs. The interpretation of the obtained results highlights the key methodological challenges to be solved to consider this approach as a robust alternative to the mainstream rationale currently adopted in LCIA. Further research should focus on increasing the granularity of environmental interventions in the modeling tools to match current standards in LCA and on adapting the conceptual approach to a spatially-explicit integrated model.

  20. Improving the service life of the 100-meter Green Bank Telescope azimuth track

    2008-07-01

    The NRAO Green Bank Telescope (GBT), located in Green Bank, West Virginia, is supported by 16 steel wheels which rest upon a composite steel and concrete Azimuth Track, 210 feet (64 meters) in diameter. From the start of observing in February 2001, the Azimuth Track design presented an operational problem for NRAO. By the spring of 2001, slippage of the top plate on the base plate was causing hold-down bolt failures. In July 2002, wear between the top and base plates (fretting) had become evident around the entire track circumference. NRAO engineers took immediate action to reduce both the track slippage and wear problems. But in January 2003, cracks were discovered in two adjacent top plates; by 2006 the top plates were cracking at a rate of almost one a month - an alarming rate given the design service life of 20 years. This paper will summarize the engineering analysis efforts that were subsequently conducted to assess the root cause of the GBT track degradation problem. We will also discuss a trial modification section that was installed in June 2004. Finally, we will discuss the design solution that was developed to remedy the track performance problem.

    Despite the increasing awareness of our dependence on Ecosystem Services (ES), Life Cycle Impact Assessment (LCIA) does not explicitly and fully assess the damages caused by human activities on ES generation. Recent improvements in LCIA focus on specific cause-effect chains, mainly related to land use changes, leading to Characterization Factors (CFs) at the midpoint assessment level. However, despite the complexity and temporal dynamics of ES, current LCIA approaches consider the environmental mechanisms underneath ES to be independent from each other and devoid of dynamic character, leading to constant CFs whose representativeness is debatable. This paper takes a step forward and is aimed at demonstrating the feasibility of using an integrated earth system dynamic modeling perspective to retrieve time- and scenario-dependent CFs that consider the complex interlinkages between natural processes delivering ES. The GUMBO (Global Unified Metamodel of the Biosphere) model is used to quantify changes in ES production in physical terms - leading to midpoint CFs - and changes in human welfare indicators, which are considered here as endpoint CFs. The interpretation of the obtained results highlights the key methodological challenges to be solved to consider this approach as a robust alternative to the mainstream rationale currently adopted in LCIA. Further research should focus on increasing the granularity of environmental interventions in the modeling tools to match current standards in LCA and on adapting the conceptual approach to a spatially-explicit integrated model.

    The analysis of ecosystem services (ES) is becoming a key-factor to implement policies on sustainable technologies. Accordingly, life cycle impact assessment (LCIA) methods are more and more oriented toward the development of harmonized characterization models to address impacts on ES. However, such efforts are relatively recent and have not reached full consensus yet. We investigate here on the transdisciplinary pillars related to the modeling of LCIA on ES by conducting a critical review and comparison of the state-of-the-art in both LCIA and ES domains. We observe that current LCIA practices to assess impacts on "ES provision" suffer from incompleteness in modeling the cause-effect chains; the multifunctionality of ecosystems is omitted; and the "flow" nature of ES is not considered. Furthermore, ES modeling in LCIA is limited by its static calculation framework, and the valuation of ES also experiences some limitations. The conceptualization of land use (changes) as the main impact driver on ES, and the corresponding approaches to retrieve characterization factors, eventually embody several methodological shortcomings, such as the lack of time-dependency and interrelationships between elements in the cause-effect chains. We conclude that future LCIA modeling of ES could benefit from the harmonization with existing integrated multiscale dynamic integrated approaches. PMID:26717294

    This paper presents a model that can calculate the uptake of CO2 in all existing concrete structures, including its uptake after service life. This is important for the calculation of the total CO2 uptake in the society and its time dependence. The model uses the well-documented cement use and knowledge of how the investments are distributed throughout the building sector to estimate the stock of concrete applications in a country. The depth of carbonation of these applications is estimated using two models, one theoretical and one based on field measurements. The maximum theoretical uptake potential is defined as the amount of CO2 that is emitted during calcination at the production of Portland cement, but the model can also, with some adjustments, be used for the other cement types. The model has been applied on data from Sweden and the results show a CO2 uptake in 2011 in all existing structures of about 300,000 tonnes, which corresponds to about 17% of the total emissions (calcination and fuel) from the production of new cement for use in Sweden in the same year. The study also shows that in the years 2030 and 2050, an increase in the uptake in crushed concrete, from 12,000 tonnes today to 200,000 and 500,000 tonnes of CO2, respectively, could be possible if the waste handling is redesigned.

    Objective Researchers have identified significant limitations in some currently-used measures of health literacy. The purpose of this paper is to present data on the relation of health-related quality of life, health status, and health service utilization to performance on a new measure of health literacy in a nonpatient population. Methods The new measure was administered to 475 English- and Spanish-speaking community-dwelling volunteers along with existing measures of health literacy and assessments of health-related quality of life, health status, and healthcare service utilization. Relations among measures were assessed via correlations and health status and utilization was tested across levels of health literacy using ANCOVA models. Results The new health literacy measure is significantly related to existing measures of health literacy as well as to participants’ health-related quality of life. Persons with lower levels of health literacy reported more health conditions, more frequent physical symptoms, and greater healthcare service utilization. Conclusion The new measure of health literacy is valid and shows relations to measures of conceptually-related constructs such as quality of life and health behaviors. Practice Implications: FLIGHT/VIDAS may be useful to researchers and clinicians interested in a computer administered and scored measure of health literacy. PMID:24856447

    Basic statements of the Concept of Extending the Service Life of the VVER-440-Based Power Units at the Novovoronezh NPP beyond 45 years are considered. This topic is raised in connection with the fact that that in December 2016 and in December 2017 the extended service lives of Units 3 and 4 at this NPP will expire. The adopted concept of repeatedly extending the service life of the Novovoronezh NPP Unit 4 implies fitting the power unit with additional reactor core cooling systems with a view to extend the (ultimate) design-basis accidents (which have hitherto been adopted to be a loss of coolant accident involving a leak of reactor coolant through a break with a nominal diameter of 100 mm) to a reactor coolant leak equivalent to rupture of the main reactor coolant pipeline. The modified Unit 4 will also use the safety systems of Unit 3 that is going to be decommissioned. Preliminary calculated assessments of the new design-basis accident scenario involving rupture of the reactor coolant pipeline in Unit 4 fitted with a new configuration of safety systems confirmed the correctness of the adopted concept of repeatedly extending the service life of Unit 4.

    The increasing damage caused by natural disasters in the last decades points out the need for interoperable added-value services to support environmental safety and human protection, by reducing vulnerability of exposed elements as well as improving the resilience of the involved communities. For this reason, to provide access to harmonized and customized data is only one of several steps towards delivering adequate support to risk assessment, reduction and management. Scope of the present work is to illustrate a methodology under development for analysis of potential impacts in areas prone to landslide hazard in the framework of the EC project LIFE+IMAGINE. The project aims to implement an infrastructure based on web services for environmental analysis, that integrates in its own architecture specifications and results from INSPIRE, SEIS and GMES. Existing web services will be customized during the project to provide functionalities for supporting the environmental integrated management. The implemented infrastructure will be applied to landslide risk scenarios, to be developed in selected pilot areas, aiming at: i) application of standard procedures to implement a landslide risk analysis; ii) definition of a procedure for assessment of potential environmental impacts, based on a set of indicators to estimate the different exposed elements with their specific vulnerability in the pilot area. More in detail, the landslide pilot will be aimed at providing a landslide risk scenario through the implementation and analysis of: 1) a landslide inventory from available historical databases and maps; 2) landslide susceptibility and hazard maps; 3) assessment of exposure and vulnerability on selected typologies of elements at risk; 4) implementation of a landslide risk scenario for different sets of exposed elements (e.g. population, road network, residential area, cultural heritage). The pilot will be implemented in Liguria, Italy, in two different catchment areas located

    The remaining useful life of an electric submersible pump (ESP) is an important economic consideration in deciding whether the used pump should be returned to service without repair. This paper presents quantitative and qualitative techniques to determine the type and amount of wear that a pump has experienced from analysis of pump test data. This paper discusses methods of categorizing used pumps, depending on the wear and associated performance deterioration. This work also describes failure modes, pump reliability, and the concept of pump (product) infant mortality. The authors show that a used pump can be more reliable and have a longer run life than a new or rebuilt pump. They use test data, tear-down analysis, and a case history to develop these concepts.

    Hospice developed in the United States in the 1970s as a way to address unmet needs for end-of-life care: support for pain and symptom management provided in the location and manner that the patient and family prefer. In Europe and Australia, hospice is available from the time of diagnosis of an advanced life-limiting illness onward, but in the United States, the Medicare hospice benefit restricts eligibility for these services to patients who no longer receive curative treatment. We provide background and analysis of the first Medicare hospice demonstration in 35 years that will test the concurrent provision of curative and hospice services for terminally ill individuals with a life expectancy of six months or less. This demonstration is a harbinger of potential policy changes to hospice and palliative care in the United States that could reduce barriers to end-of-life care that aligns with patient and family preferences as the demand for care increases with an aging population.

    The NASA s Evolutionary Xenon Thruster (NEXT) program is tasked with significantly improving and extending the capabilities of current state-of-the-art NSTAR thruster. The service life capability of the NEXT ion thruster is being assessed by thruster wear test and life-modeling of critical thruster components, such as the ion optics and cathodes. The NEXT Long-Duration Test (LDT) was initiated to validate and qualify the NEXT thruster propellant throughput capability. The NEXT thruster completed the primary goal of the LDT; namely to demonstrate the project qualification throughput of 450 kg by the end of calendar year 2009. The NEXT LDT has demonstrated 28,500 hr of operation and processed 466 kg of xenon throughput--more than double the throughput demonstrated by the NSTAR flight-spare. Thruster performance changes have been consistent with a priori predictions. Thruster erosion has been minimal and consistent with the thruster service life assessment, which predicts the first failure mode at greater than 750 kg throughput. The life-limiting failure mode for NEXT is predicted to be loss of structural integrity of the accelerator grid due to erosion by charge-exchange ions.

    samples suffered less than 1% in when exposed to contaminants such as HCl(g), Hg(g), and Zn(g), and SbO(g) at levels of 8 ppm and above. AsH3 vapor at 0.5 ppm did not affect the electrical performance of an SOFC sample even after 1000 h at 750°C. In Phase II of the program, long-term tests will be performed with multiple contaminants at a temperature range of 750° to 850°C. These tests will be at contaminant levels typical of coal-derived gas streams that have undergone gas cleanup using Selexol technology. The chemical nature of the contaminant species will be identified at the operating temperature of SOFC and compare them with thermodynamic equilibrium calculations. The results of the testing will be used to recommend the sensitivity limits for SOFC operation and to assess the reduction in the service life of the SOFC for trace level contaminants.

    This study assessed the role of some common mental health conditions as mediators in the pathway between suffering life events and using mental health services. The participants were from the Baltimore Epidemiologic Catchment Area cohort, interviewed in 1993 to 1996 and 2004 to 2005. Longitudinal data analysis was used to identify models with significant mediation. Only alcohol abuse/dependence disorder was a significant mediator in the pathway between suffering a life-threatening illness and using mental health services in a general medical setup. Female gender, being more than 65 years old, prior use of services and availability of health insurance were some of the factors that significantly predicted service use in that model. Some of other factors like social networks and social support, attitudes towards services, and stigma, may play a role in determining service use. Future research should investigate the role of such factors as mediators for mental health service use. PMID:20215995

Integration and interoperability of such resources are crucial for sharing content across research domains relevant to the life sciences. In this article we present a perspective review of data integration with emphasis on a semantics driven approach to data integration that pushes content into a shared infrastructure, reduces data redundancy and clarifies any inconsistencies. This enables much improved access to life science data from numerous primary sources. The Semantic Enrichment of the Scientific Literature (SESL) pilot project demonstrates feasibility for using already available open semantic web standards and technologies to integrate public and proprietary data resources, which span structured and unstructured content. This has been accomplished through a precompetitive consortium, which provides a cost effective approach for numerous stakeholders to work together to solve common problems.

    In recent years, there has been a significant increase in the development and application of technical decentralized filter systems for the treatment of runoff from traffic areas. However, there are still many uncertainties regarding the service life and the performance of filter materials that are employed in decentralized treatment systems. These filter media are designed to prevent the transport of pollutants into the environment. A novel pilot-scale test method was developed to determine - within a few days - the service lives and long-term removal efficiencies for dissolved heavy metals in stormwater treatment systems. The proposed method consists of several steps including preloading the filter media in a pilot-scale model with copper and zinc by a load of n-1 years of the estimated service life (n). Subsequently, three representative rain events are simulated to evaluate the long-term performance by dissolved copper and zinc during the last year of application. The presented results, which verified the applicability of this method, were obtained for three filter channel systems and six filter shaft systems. The performance of the evaluated systems varied largely for both tested heavy metals and during all three simulated rain events. A validation of the pilot-scale assessment method with field measurements was also performed for two systems. Findings of this study suggest that this novel method does provide a standardized and accurate estimation of service intervals of decentralized treatment systems employing various filter materials. The method also provides regulatory authorities, designers, and operators with an objective basis for performance assessment and supports stormwater managers to make decisions for the installation of such decentralized treatment systems.

    The three-jet direct-flow plasma reactor with a channel diameter of 0.054 m was studied in terms of service life, thermal, technical, and functional capabilities. It was established that the near-optimal combination of thermal efficiency, required specific enthalpy of the plasma-forming gas and its mass flow rate is achieved at a reactor power of 150 kW. The bulk temperature of plasma flow over the rector of 12 gauges long varies within 5500÷3200 K and the wall temperature within 1900÷850 K, when a cylinder from zirconium dioxide of 0.005 m thick is used to thermally insulate the reactor. The specific electric power reaches a high of 1214 MW/m3. The rated service life of electrodes is 4700 hours for a copper anode and 111 hours for a tungsten cathode. The projected contamination of carbides and borides with elec-trode-erosion products doesn't exceed 0.0001% of copper and 0.00002% of tungsten.

    Introduction Pregnancy-related mortality and morbidity in most low and middle income countries can be reduced through early recognition of complications, prompt access to care and appropriate medical interventions following obstetric emergencies. We used the three delays framework to explore barriers to emergency obstetric care (EmOC) services by women who experienced life threatening obstetric complications in Malindi District, Kenya. Methods A facility-based qualitative study was conducted between November and December 2010. In-depth interviews were conducted with 30 women who experienced obstetric “near miss” at the only public hospital with capacity to provide comprehensive EmOC services in the district. Resuls Findings indicate that pregnant women experienced delays in making decision to seek care and in reaching an appropriate care facility. The “first” delay was due to lack of birth preparedness, including failure to identify a health facility for delivery services regardless of antenatal care and to seek care promptly despite recognition of danger signs. The “second” delay was influenced by long distance and inconvenient transport to hospital. These two delays resulted in some women arriving at the hospital too late to save the life of the unborn baby. Conclusion Delays in making the decision to seek care when obstetric complications occur, combined with delays in reaching the hospital, contribute to ineffective treatment upon arrival at the hospital. Interventions to reduce maternal mortality and morbidity must adequately consider the pre-hospital challenges faced by pregnant women in order to influence decision making towards addressing the three delays.

    Since the beginning of the eighties scrubbers and other components in European FGD plants have been protected against corrosion using rubber lining. Extensive experience is available based on service lives of rubber lining of more than 15 years. The paper will consider the various rubber types and curing systems used. While the USA and Japan had already begun retrofitting their existing coal-fired power stations with flue gas desulfurization (FGD) plants in the seventies, Germany followed suit in the eighties as a result of the decree issued for large-scale firing plants. Concurrent with this development retrofitting has also been enhanced in other European countries like Austria and the Netherlands, later followed by Denmark, Finland and England. After the collapse of the Eastern Bloc retrofitting work has been implemented in Eastern Germany, Poland, the Czech Republic and Slovakia. Today FGD plants are being put into operation in Spain, Italy, Turkey and Greece or are on the verge of being put into service. More than 150 plants of this kind are operated by using the wet-scrubbing process with limestone or calcium hydroxide suspensions.

    An investigation to establish the cause and, devise a repair technique to maintain the serviceability of the DSS-13 26 meter antenna is described. Core samples are obtained from the concrete and various laboratory tests conducted. In-place nondestructive type tests are also performed. The tests established that the concrete is deteriorating because of alkali aggregate reactivity. This is a phenomenon wherein certain siliceous constituents present in some aggregates react with alkalies in the portland cement to produce a silica gel which, in turn, imbibes water, swells, and cracks the concrete. The scheme consists of a supplemental steel frame friction pile anchored grade beam encircling the existing foundation. This system provides adequate bracing against base shear and overturning due to seismic loading. Larger cracks are sealed using a pressure injected two-component epoxy.

    Aims Epidemiological surveys over the last 20 years show a steady increase in the amount of alcohol consumed by older age groups. Physiological changes and an increased likelihood of health problems and medication use make older people more likely than younger age groups to suffer negative consequences of alcohol consumption, often at lower levels. However, health services targeting excessive drinking tend to be aimed at younger age groups. The aim of this study was to gain an in-depth understanding of experiences of, and attitudes towards, support for alcohol related health issues in people aged 50 and over. Methods Qualitative interviews (n = 24, 12 male/12 female, ages 51–90 years) and focus groups (n = 27, 6 male/21 female, ages 50–95 years) were carried out with a purposive sample of participants who consumed alcohol or had been dependent. Findings Participants’ alcohol misuse was often covert, isolated and carefully regulated. Participants tended to look first to their General Practitioner for help with alcohol. Detoxification courses had been found effective for dependent participants but only in the short term; rehabilitation facilities were appreciated but seen as difficult to access. Activities, informal groups and drop-in centres were endorsed. It was seen as difficult to secure treatment for alcohol and mental health problems together. Barriers to seeking help included functioning at a high level, concern about losing positive aspects of drinking, perceived stigma, service orientation to younger people, and fatalistic attitudes to help-seeking. Facilitators included concern about risk of fatal illness or pressure from significant people. Conclusion Primary care professionals need training on improving the detection and treatment of alcohol problems among older people. There is also a compelling need to ensure that aftercare is in place to prevent relapse. Strong preferences were expressed for support to be provided by those who had experienced

    Objective Although recent studies have improved understanding of quality of life (QOL) outcomes of breast conserving surgery, few have used longitudinal data for more than two time points, and few have examined predictors of QOL over two years. Additionally, the longitudinal data analyses in such studies rarely apply the appropriate statistical methodology to control for censoring and inter-correlations arising from repeated measures obtained from the same patient pool. This study evaluated an internet-based system for measuring longitudinal changes in QOL and developed a cloud-based system for managing patients after breast conserving surgery. Methods This prospective study analyzed 657 breast cancer patients treated at three tertiary academic hospitals. Related hospital personnel such as surgeons and other healthcare professionals were also interviewed to determine the requirements for an effective cloud-based system for surveying QOL in breast cancer patients. All patients completed the SF-36, Quality of Life Questionnaire (QLQ-C30) and its supplementary breast cancer measure (QLQ-BR23) at baseline, 6 months, 1 year, and 2 years postoperatively. The 95% confidence intervals for differences in responsiveness estimates were derived by bootstrap estimation. Scores derived by these instruments were interpreted by generalized estimating equation before and after surgery. Results All breast cancer surgery patients had significantly improved QLQ-C30 and QLQ-BR23 subscale scores throughout the 2-year follow-up period (p<0.05). During the study period, QOL generally had a negative association with advanced age, high Charlson comorbidity index score, tumor stage III or IV, previous chemotherapy, and long post-operative LOS. Conversely, QOL was positively associated with previous radiotherapy and hormone therapy. Additionally, patients with high scores for preoperative QOL tended to have high scores for QLQ-C30, QLQ-BR23 and SF-36 subscales. Based on the results of

  13. Towards Practical Carbonation Prediction and Modelling for Service Life Design of Reinforced Concrete Structures

    2015-11-01

    Amongst the scientific community, the interest in durability of concrete structures has been high for quite a long time of over 40 years. Of the various causes of degradation of concrete structures, corrosion is the most widespread durability problem and carbonation is one of the two causes of steel reinforcement corrosion. While much scientific understanding has been gained from the numerous carbonation studies undertaken over the past years, it is still presently not possible to accurately predict carbonation and apply it in design of structures. This underscores the complex nature of the mechanisms as influenced by several interactive factors. Based on critical literature and some experience of the author, it is found that there still exist major challenges in establishing a mathematical constitutive relation for realistic carbonation prediction. While most current models employ permeability /diffusion as the main model property, analysis shows that the most practical material property would be compressive strength, which has a low coefficient of variation of 20% compared to 30 to 50% for permeability. This important characteristic of compressive strength, combined with its merit of simplicity and data availability at all stages of a structure's life, promote its potential use in modelling over permeability. By using compressive strength in carbonation prediction, the need for accelerated testing and permeability measurement can be avoided. This paper attempts to examine the issues associated with carbonation prediction, which could underlie the current lack of a sound established prediction method. Suggestions are then made for possible employment of different or alternative approaches.

    This study aimed at assessing the relationship between dental pain and the reason for using dental services and oral health quality of life in people aged 50 to 74 years in southern Brazil. A cross-sectional population-based study was conducted with 720 individuals aged 50 to 74 years, living in three health districts in the city of Porto Alegre. Dental impacts on daily life and sociodemographic data were assessed using structured interviews. The Oral Impacts on Daily Performance - OIDP instrument was used to measure oral impacts. The information was analyzed by Poisson regression with robust variance adjustment, taking into account cluster sampling. Dental pain was present in 32.5% of those reporting an oral impact on their daily activities. Dental pain most frequently affected talking (37.6%), cleaning teeth and gums (37.0%) and enjoying the companionship of people (36.5%). After adjustments to the multivariate analysis, the reason for dental visits due to dental pain was found to have a high impact on daily activities [RP 1.68 (1.11 - 2.54]. PMID:27556550

  15. Harm reduction services as a point-of-entry to and source of end-of-life care and support for homeless and marginally housed persons who use alcohol and/or illicit drugs: a qualitative analysis

    PubMed Central

    2012-01-01

    Background Homeless and marginally housed persons who use alcohol and/or illicit drugs often have end-of-life care needs that go unmet due to barriers that they face to accessing end-of-life care services. Many homeless and marginally housed persons who use these substances must therefore rely upon alternate sources of end-of-life care and support. This article explores the role of harm reduction services in end-of-life care services delivery to homeless and marginally housed persons who use alcohol and/or illicit drugs. Methods A qualitative case study design was used to explore end-of-life care services delivery to homeless and marginally housed persons in six Canadian cities. A key objective was to explore the role of harm reduction services. 54 health and social services professionals participated in semi-structured qualitative interviews. All participants reported that they provided care and support to this population at end-of-life. Results Harm reduction services (e.g., syringe exchange programs, managed alcohol programs, etc.) were identified as a critical point-of-entry to and source of end-of-life care and support for homeless and marginally housed persons who use alcohol and/or illicit drugs. Where possible, harm reduction services facilitated referrals to end-of-life care services for this population. Harm reduction services also provided end-of-life care and support when members of this population were unable or unwilling to access end-of-life care services, thereby improving quality-of-life and increasing self-determination regarding place-of-death. Conclusions While partnerships between harm reduction programs and end-of-life care services are identified as one way to improve access, it is noted that more comprehensive harm reduction services might be needed in end-of-life care settings if they are to engage this underserved population.

    Residential thermostats have been a key element in controlling heating and cooling systems for over sixty years. However, today's modern programmable thermostats (PTs) are complicated and difficult for users to understand, leading to errors in operation and wasted energy. Four separate tests of usability were conducted in preparation for a larger study. These tests included personal interviews, an on-line survey, photographing actual thermostat settings, and measurements of ability to accomplish four tasks related to effective use of a PT. The interviews revealed that many occupants used the PT as an on-off switch and most demonstrated little knowledge of how to operate it. The on-line survey found that 89% of the respondents rarely or never used the PT to set a weekday or weekend program. The photographic survey (in low income homes) found that only 30% of the PTs were actually programmed. In the usability test, we found that we could quantify the difference in usability of two PTs as measured in time to accomplish tasks. Users accomplished the tasks in consistently shorter times with the touchscreen unit than with buttons. None of these studies are representative of the entire population of users but, together, they illustrate the importance of improving user interfaces in PTs.

    Service life assessment of three historical building envelopes constructed using different types of sandstone is presented. At first, experimental measurements of material parameters of sandstones are performed to provide the necessary input data for a subsequent computational analysis. In the second step, the moisture and temperature fields across the studied envelopes are calculated for a representative period of time. The computations are performed using dynamic climatic data as the boundary conditions on the exterior side of building envelope. The climatic data for three characteristic localities are experimentally determined by the Czech Hydrometeorological Institute and contain hourly values of temperature, relative humidity, rainfalls, wind velocity and direction, and sun radiation. Using the measured durability properties of the analyzed sandstones and the calculated numbers of freeze/thaw cycles under different climatic conditions, the service life of the investigated building envelopes is assessed. The obtained results show that the climatic conditions can play a very significant role in the service life assessment of historical buildings, even in the conditions of such a small country as the Czech Republic. In addition, the investigations reveal the importance of the material characteristics of sandstones, in particular the hygric properties, on their service life in a structure. PMID:25114972

    Purpose of review In this review, we briefly summarize three fruitful, emerging areas in liver transplantation research: quality of life; risk assessment; and patient safety. Our goal is to highlight recent findings in these areas, with a call for increased integration of social scientists and transplant clinicians to address how best to shape policy and improve outcomes. Recent findings After liver transplantation, recipients generally experience clinically significant, sustained improvement in their physical, social and emotional well-being. However, a sizeable minority of patients do experience excess morbidity that may benefit from ongoing surveillance and/or intervention. There is growing body of research that describes risks associated with liver transplantation, which can be useful aids to better inform decision making by patients, clinicians, payers, and policy makers. In contrast, there has been a relative lack of empirical data on transplant patient safety vulnerabilities, placing the field of surgery in stark contrast to other high risk industries, where such assessments inform continuous process improvement. Summary Health services and outcomes research has grown in importance in the liver transplantation literature, but several important questions remain unanswered that merit programmatic, interdisciplinary research.

    Major internal components of WWER-type nuclear reactors are made from annealed 18Cr10NiTi steel, a close analog to AISI 321. Void swelling of the baffle ring in particular could be a major factor limiting operation of the reactor beyond the current 30 years license. A predictive swelling equation is needed to forecast the spatial variation of swelling so as to identify those areas requiring additional attention. Available data on the swelling of this steel arising from irradiation in the BOR-60 fast reactor was combined with data from a heavy ion accelerator at higher displacement rates to formulate a predictive equation of swelling for the WWER-relevant range of temperature, irradiation dose and dose rates. This equation was used to estimate the swelling distribution over a cross-section of the baffle ring of a WWER reactor during a service life up to 60 years, reaching a local maximum of ˜30% swelling. It was shown that void swelling extends over a larger portion of the baffle ring than previously expected and exhibits a very complex and irregular distribution in response to complex distributions of temperature and dpa rate. Most importantly, as operation is extended beyond 30 years several areas of the ring may experience swelling in excess of 10% where void-induced embrittlement begins and one area may exceed 20% after 45 years, a swelling level where a complete loss of ductility is known to occur.

  12. The actual goals of geoethics

    The most actual goals of geoethics have been formulated as results of the International Conference on Geoethics (October 2013) held at the geoethics birth-place Pribram (Czech Republic): In the sphere of education and public enlightenment an appropriate needed minimum know how of Earth sciences should be intensively promoted together with cultivating ethical way of thinking and acting for the sustainable well-being of the society. The actual activities of the Intergovernmental Panel of Climate Changes are not sustainable with the existing knowledge of the Earth sciences (as presented in the results of the 33rd and 34th International Geological Congresses). This knowledge should be incorporated into any further work of the IPCC. In the sphere of legislation in a large international co-operation following steps are needed: - to re-formulate the term of a "false alarm" and its legal consequences, - to demand very consequently the needed evaluation of existing risks, - to solve problems of rights of individuals and minorities in cases of the optimum use of mineral resources and of the optimum protection of the local population against emergency dangers and disasters; common good (well-being) must be considered as the priority when solving ethical dilemmas. The precaution principle should be applied in any decision making process. Earth scientists presenting their expert opinions are not exempted from civil, administrative or even criminal liabilities. Details must be established by national law and jurisprudence. The well known case of the L'Aquila earthquake (2009) should serve as a serious warning because of the proven misuse of geoethics for protecting top Italian seismologists responsible and sentenced for their inadequate superficial behaviour causing lot of human victims. Another recent scandal with the Himalayan fossil fraud will be also documented. A support is needed for any effort to analyze and to disclose the problems of the deformation of the contemporary

    US infrastructure expanded dramatically in the mid-20th century, and now includes more than 79,000 dams, 15,000 miles of levees, 3.7 million miles of roads, 600,000 miles of sewer pipe, 500,000 onshore oil wells, and over 4,000 offshore oil platforms. Many structures have been in place for 50 years or more, and an increasing portion of national infrastructure is approaching or exceeding its originally intended design life. Bringing national infrastructure to acceptable levels would cost nearly 10% of the US annual GDP. Decommissioning infrastructure can decrease public spending and increase public safety while facilitating economic expansion and ecological restoration. While most infrastructure remains critical to the national economy, a substantial amount is obsolete or declining in importance. Over 11,000 dams are abandoned, and of nearly 400,000 miles of road on its lands, the U.S. Forest Service considers one-fourth non-essential and often non-functional. Removing obsolete infrastructure allows greater focus and funding on maintaining or improving infrastructure most critical to society. Moreover, a concerted program of infrastructure decommissioning promises significant long-term cost savings, and is a necessary step before more substantial, systematic changes are possible, like those needed to address the new energy sources and shifting climate. One key challenge for infrastructure reform is how to prioritize and implement such a widespread and politically-charged series of decisions. Two approaches are proposed for different scales. For small, private infrastructure, emerging state and federal ecosystem service markets can provide an economic impetus to push infrastructure removal. Ecosystem market mechanisms may also be most effective at identifying those projects with the greatest ecological bang for the buck. Examples where this approach has proved successful include dam removal for stream mitigation under the Clean Water Act, and levee decommissioning on

    Background: Despite advances in the treatment of childhood cancer, some children continue to die from their disease. This study aimed to assess the impact of specialist paediatric palliative care services (SPPCSs) on the number of hospital admissions in children who subsequently died from cancer in Yorkshire, UK. Methods: An extract of patients aged 0–19 years from the Yorkshire Specialist Register of Cancer in Children and Young People (YSRCCYP) diagnosed from 1990 to 2009 were linked to inpatient hospital episodes data and a SPPCS database. Deaths were included if they occurred before 31 August 2011. Differences in hospital admission patterns were assessed using negative binomial regression and presented as incidence rate ratios (IRRs). Results: Of 2508 children on the YSRCCYP, 657 (26%) had died by the censoring date. A total of 211 children had been referred to the local SPPCS, of whom 182 (86%) had subsequently died. Referral to SPPCS was associated with a significant reduction in the rate of planned hospital admissions (IRR=0.60, 95% CI 0.43–0.85). Central nervous system tumours showed significant decreases for all planned and emergency admissions compared with all other diagnostic groups. Conclusion: Referral to SPPCS significantly reduced the number of planned hospital admissions for children and young people with cancer before their death, which are often integral to paediatric oncology treatment regimens. Overall, our findings show that SPPCS have a role in reducing hospital admissions during end of life care of paediatric cancer patients with potential personal, social and economic benefits.

    Children with life limiting conditions and their families have complex needs. Evaluations must consider their views and perspectives to ensure care is relevant, appropriate and acceptable. We consulted with children, young people, their parents and local professionals to gain a more informed picture of issues affecting them prior to preparing a bid to evaluate services in the area. Multiple methods included focus groups, face-to-face and telephone interviews and participatory activities. Recordings and products from activities were analysed for content to identify areas of relevance and concern. An overarching theme from parents was 'Why does it happen like this?' Services did not seem designed to meet their needs. Whilst children and young people expressed ideas related to quality of environment, services and social life, professionals focused on ways of meeting the families' needs. The theme that linked families' concerns with those of professionals was 'assessing individual needs'. Two questions to be addressed by the evaluation are (1) to what extent are services designed to meet the needs of children and families and (2) to what extent are children, young people and their families consulted about what they need? Consultations with families and service providers encouraged us to continue their involvement as partners in the evaluation. PMID:24270996

  17. Durability assessment results suggest a serviceable life of two, rather than three, years for the current long-lasting insecticidal (mosquito) net (LLIN) intervention in Benin

    PubMed Central

    2014-01-01

    Background LLIN distribution, every three years, is a key intervention of Benin’s malaria control strategy. However, data from the field indicate that LLIN lifespan appears to vary based on both intrinsic (to the LLIN) and extrinsic factors. Methods We monitored two indicators of LLIN durability, survivorship and integrity, to validate the three-year-serviceable-life assumption. Interviews with net owners were used to identify factors associated with loss of integrity. Results Observed survivorship, after 18 months, was significantly less (p<0.0001) than predicted, based on the assumption that nets last three years. Instead, it was closer to predicted survivorship based on a two-year LLIN serviceable life assumption (p=0.03). Furthermore, the integrity of nearly one third of ‘surviving’ nets was so degraded that they were in need of replacement. Five factors: washing frequency, proximity to water for washing, location of kitchen, type of cooking fuel, and low net maintenance were associated with loss of fabric integrity. Conclusion A two-year serviceable life for the current LLIN intervention in Benin would be a more realistic program assumption. PMID:24507444

    This study explored the growth experiences of women abused by their intimate partner, specifically focusing on the associations between social services and empowerment, perceived changes of self, and life satisfaction. The potential effects of demographic variables, social support, coping, and experience of partner abuse were also explored. A survey study was conducted through the collaboration of social workers in the Centers of Prevention and Intervention for Domestic Violence and private sectors in Taiwan. Through contact by their social workers, 191 participants completed the questionnaires. The results revealed that the participants had growth mainly in their psychological and interpersonal domains. The independent variables in the regression model explained 45.3% (adjusted) variance in perceived changes of self. In addition to empowerment and negative impact of violence, intensity of contact and professional relationship were two important service variables that directly and significantly correlated with perceived changes of self. A significant amount of variance (adjusted R² = .556) in life satisfaction could be explained by the independent variables. Social support and empowerment directly correlated with life satisfaction. The findings also supported the mediation effect of empowerment. Seven variables (e.g., social support, coping method, and professional relationship) indirectly associated with perceived changes of self and life satisfaction through empowerment.

    This paper reports on creep-fatigue strength of post-service 2 {center dot} 1/4 Cr-1 {center dot} Mo steel used for about one hundred-thousand hours in a fossil fuel power plant. The creep-fatigue strength of the post-service material was lower than that of the virgin material, whereas it was comparable to that of thermally aged material, which was artificially exposed at high temperature for a long time so that it had an equivalent value of the Larson-Miller parameter to the post-service material. The nondestructive detection of the long-term degradation damage due to long-term thermal aging, as well as due to creep-fatigue, was also investigated by applying an ultrasonic technique. It was found that the energy attenuation coefficient, {alpha}, which is defined by the ratio of input to output energies of a longitudinal ultrasonic wave, had a good correlation with creep-fatigue damage in the virgin, aged and post-service materials; and hence, {alpha} was a successful parameter to detect creep-fatigue damage. Based on the results thus obtained, a new remaining life estimation method for creep-fatigue of in-service high-temperature materials was proposed. The application of the method to the post-service material tested gave good predicted results.

  20. Quality of life of caregivers with relatives suffering from mental illness in Hong Kong: roles of caregiver characteristics, caregiving burdens, and satisfaction with psychiatric services

    2012-01-01

    Background The study attempted to explore the quality of life (QoL) of Chinese caregivers with mentally ill relatives. It also aimed to examine the differential roles of caregiving burdens, caregiver characteristics, and satisfaction with psychiatric services in caregivers' QoL. Methods 276 caregivers with relatives attending community psychiatric facilities in Hong Kong were invited to fill out a questionnaire. One sample t-tests were conducted to compare the results of this study with that of other Chinese populations in Hong Kong, Taiwan, and mainland China. A hierarchical regression analysis was performed to examine the relative influence of different factors on caregivers' QoL. Results Our sample of caregivers had significantly lower QoL scores than other Chinese populations. Results also suggest that Chinese caregivers who had chronic illness, younger in age, a lower education level, experienced more difficulties in handling negative symptoms, and were more dissatisfied with mental health services had poorer quality of life. Indeed, caregiver characteristics displayed a much stronger association with caregivers' QoL than did caregiving burdens and satisfaction with psychiatric services. Conclusions This study supports the strong association of caregiver characteristics and the QoL of caregivers and establishes the nature of the relationship between satisfaction with mental health services and caregiver QoL. Implications for future research and practice are discussed. PMID:22289443

    2016-01-01

    Background: Home-based palliative services form the cornerstone of Kerala's palliative program. However, two issues need research: (a) whether family-homes can be considered as the locus of ageing and dying for marginal populations who experience deprivation and poverty and (b) whether the present delivery structure meets the needs of elderly population. These issues are examined in the context of two rural areas. The study explores end-of-life characteristics of the elderly – their sociodemographic status and living patterns, morbidity profile, and functional status. It also looks into the accessibility and utilization of palliative services and respondents’ satisfaction with different components of the services. Materials and Methods: A descriptive cross-sectional survey design is used. Data were collected based on the interviews of sixty service users sampled randomly from a roster of palliative care services. Semi-structured interviews were substantiated by personal field observations. Results: The study has found people living under extreme financial distress with inadequate shelter and poor social security provisions. The health profile is characterized by high level of functional dependence. Many dependent widowed women were living alone without appropriate care and shelter. The palliative program as perceived by the respondents is characterized by few doctor visitations and poor frequency. Conclusion: The study concludes that home-based palliation in its present form does not promote good end-of-life care. It lacks an integrated approach with good service-mix. It raises serious questions on family-home as the locus of ageing and dying for marginal populations, and suggests need for restructuring of the palliative program. PMID:27803573

    Introduction Attendance at emergency departments and unplanned hospital readmissions are common for frail older patients after discharge from hospitals. A virtual ward service was piloted to deliver “hospital-at-home” services by community nurses and geriatricians to frail older patients immediately after their discharge from hospital to reduce emergency services utilization. Objectives This study examined the impacts of the virtual ward service on changes in the patients’ emergency attendance and medical readmissions, and their quality of life (QOL). Methods A matched-control quasi-experimental study was conducted at four hospitals, with three providing the virtual ward service (intervention) and one providing the usual community nursing care (control). Subjects in the intervention group were those who are at high risk of readmission and who are supported by home carers recruited from the three hospitals providing the virtual ward service. Matched control patients were those recruited from the hospital providing usual care. Outcome measures include emergency attendance and medical readmission in the past 90 days as identified from medical records, and patient-reported QOL as measured by the modified Quality-of-Life Concerns in the End of Life Questionnaire (Chinese version). Wilcoxon signed-rank tests compared the changes in the outcome variables between groups. Results A total of 39 patients in each of the two groups were recruited. The virtual ward group showed a greater significant reduction in the number of unplanned emergency hospital readmissions (−1.41±1.23 versus −0.77±1.31; P=0.049) and a significant improvement in their overall QOL (n=18; 0.60±0.56 versus 0.07±0.56; P=0.02), but there was no significant difference in the number of emergency attendances (−1.51±1.25 versus −1.08±1.48; P=0.29). Conclusion The study results support the effectiveness of the virtual ward service in reducing unplanned emergency medical readmissions and in

The fate of transgender service members remains uncertain as the policy preventing them from serving in the military remains under review. The health care needs of these populations remain for the most part unknown, with total acceptance and integration in the military yet to be achieved. In this paper, we review the literature on the health care needs of lesbian, gay, bisexual, and transgender (LGBT) service members, relying heavily on what is known about LGBT civilian and veteran populations. Significant research gaps about the health care needs of LGBT service members are identified, along with recommendations for closing those gaps. In addition, recommendations for improving LGBT acceptance and integration within the military are provided.

Of 389 referrals in 2010/11, about 85% were for cancer, from a population of about 155 000. Using a mixed method approach, the evaluation comprised: a retrospective analysis of secondary-care use in the last year of life; financial evaluation of the MMSPCS using an Activity Based Costing approach; qualitative interviews with patients, carers, health and social care staff and MMSPCS staff and volunteers; a postal survey of General Practices; and a postal survey of bereaved caregivers using the MMSPCS. The mean cost is about 3000 GBP (3461 EUR) per patient with mean cost of interventions for cancer patients in the last year of life 1900 GBP (2192 EUR). Post-referral, overall costs to the system are similar for MMSPCS and hospice-led models; however, earlier referral avoided around 20% of total costs in the last year of life. Patients and carers reported positive experiences of support, linked to the flexible way the service worked. Seventy-one per cent of patients died at home. This model may have application elsewhere.

    In the half century since enactment of the 1965 Great Society programs, accomplishments were gradually made to improve access to and quality of long-term services and supports (LTSS), including: mitigation of financial and care abuses in nursing facilities (NFs); substantial rebalancing of LTSS towards consumer-preferred home-and-community-based services (HCBS); increasing flexible consumer-centered HCBS including payment to family caregivers; and more assisted-living and housing options for seniors with heavy care needs. A unified planning and advocacy agenda across age and disability type and greater consumer transparency fueled progress. Nonetheless, LTSS is a broken system; persistent problems interfere with substantial and necessary change. These include; over-emphasis on safety for LTSS consumers; inattention to physical environments in all settings; regulatory and professional rigidity; and poor communication and information. Our recommendations are aimed at builders and designers, LTSS professionals, regulators, and educators/trainers; the last may be crucial in forging new consensus and over-coming entrenched beliefs. Policy recommendations include relatively narrow steps-for example, requiring single occupancy in all NFs and assisted living settings financed with public dollars-to broad reworking of the prerequisites for livable age-friendly (and dementia-friendly) communities and for a capable, flexible LTSS workforce.

  14. Challenges in access to health services and its impact on quality of life: a randomised population-based survey within Turkish speaking immigrants in London

    PubMed Central

    2012-01-01

    Background and aim There are a significant number of Turkish speaking immigrants living in London. Their special health issues including women's health, mental health, and alcohol and smoking habits has been assessed. The aim of this study was to explore the ongoing challenges in access to health care services and its impact on Quality of Life of immigrants. Material and methods This cross-sectional population-based study was conducted between March and August 2010 with Turkish immigrants (n = 416) living in London. Of these, 308 (74%) were Turkish and 108 (26%) were Turkish Cypriots. All healthy or unhealthy adults of 17-65 years of age were enrolled. A structured questionnaire with 44 items in five subcategories and 26-items WHOQOL BREF were used. Results Mean duration of stay for Turkish Cypriots (26.9 ± 13.9 years) was significantly longer than Turkish immigrants (13.3 ± 7.5) (p < 0.001). Turkish immigrants (n = 108, 36.5%) need interpretation more often when using health services than Turkish Cypriots (n = 16, 15%) (p < 0.001). Multivariate analyses suggested significant effects of older age, non-homeownership, low socioeconomic class, poor access to health services, being ill, poor community integration and being obese on physical well-being and also significant effects of low income and poor community integration on perceived overall Quality of Life (WHOQOL) of the participants. Conclusions The results of this study demonstrate how the health and well-being of members of the Turkish speaking community living in London are affected by social aspects of their lives.

    Mechanical and electrical test results are reported for a power cable that has been installed for three and a half years in a high-level radiation area at the European Organization for Nuclear Research (CERN). The degradation of selected mechanical properties as a function of absorbed dose is compared with results of a short-term irradiation in a nuclear reactor. The tensile test specimens have been taken from the ethylene propylene rubber insulation and the polyvinyl chloride sheath material of the cable after exposure in service. For the measurement of breakdown voltage, short portions of insulated cable have been used. The aim of this work was to verify that the combined functional and environmental stress factors did not lead to more damage of the cable than was expected from the value of absorbed dose, and eventually to predict more precisely the service life of similar cables. The ratios of doses after service and short-term irradiation at 50% reduction of elongation at break were about 0.5 for the insulation and 1.0 for the sheath material at a dose of about 1 MGy. However, the breakdown voltage did not show any significant variation in the dose range covered up to 3.6 MGy. Therefore, a safe lower dose limit may readily be derived from accelerated tests, but the margin until failure in service remains to be determined.

    A common method of managing challenging behaviour associated with dementia is long-stay special care units, though models are very diverse. In New South Wales, Australia, the five remaining state-run long-stay special care units for this population were funded to adopt a shorter-term model which had been trialled by one of the units. Transitional Behavioural Assessment and Intervention Service Units, incorporating an integrated outreach team, were to provide multi-disciplinary assessments, develop individualised bio-psychosocial management plans for, and appropriately discharge people with significant levels of Behavioural and Psychological Symptoms in Dementia. The current study assessed both the effects of the change and the clinical effectiveness of the model.

    Background. Achievement motive is defined as the intention to achieve one’s goals. Achievement motive is assumed to promote clients to choices and actions toward their valuable goal, so it is an important consideration in rehabilitation. Purpose. The purpose of this study is to demonstrate the structural relationship among achievement motive on purpose in life, social participation, and role expectation of community-dwelling elderly people. Methods. Participants were community-dwelling elderly people in day-service centers. A total of 281 participants (male: 127, female: 154) answered the self-administered questionnaire in cross-sectional research. The questionnaire was comprised of demographic data and scales that evaluated achievement motive, social participation, purpose in life, and role expectation. We studied the structural relationship established by our hypothesized model via a structural equation modeling approach. Results. We checked the standardized path coefficients and the modification indices; the modified model’s statistics were a good fit: CFI = 0.984, TLI = 0.983, RMSEA = 0.050, 90% CI [0.044–0.055]. Achievement motive had a significantly direct effect on purpose in life (direct effect = 0.445, p value < 0.001), a significantly indirect effect on purpose in life via social participation or role expectation (indirect effect = 0.170, p value < 0.001) and a total effect on purpose in life (total effect = 0.615). Discussion. This result suggests that enhancing the intention to achieve one’s goals enables participants to feel a spirit of challenge with a purpose and a sense of fulfillment in their daily lives.

    1979-01-01

    An accelerated life test is described which was developed to predict the life of the 25 kW photovoltaic array installed near Mead, Nebraska. A quantitative model for accelerating testing using multiple environmental stresses was used to develop the test design. The model accounts for the effects of thermal stress by a relation of the Arrhenius form. This relation was then corrected for the effects of nonthermal environmental stresses, such as relative humidity, atmospheric pollutants, and ultraviolet radiation. The correction factors for the nonthermal stresses included temperature-dependent exponents to account for the effects of interactions between thermal and nonthermal stresses on the rate of degradation of power output. The test conditions, measurements, and data analyses for the accelerated tests are presented. Constant-temperature, cyclic-temperature, and UV types of tests are specified, incorporating selected levels of relative humidity and chemical contamination and an imposed forward-bias current and static electric field.

    Residual stresses introduced by manufacturing processes such as casting, forming, machining, and welding have harmful effects on the mechanical behavior of the structures. In addition to the residual stresses, weld toe stress concentration can play a determining effect. There are several methods to improve the mechanical properties such as fatigue behavior of the welded structures. In this paper, the effects of ultrasonic peening on the fatigue life of the high-temperature seamless steel pipes, used in the petrochemical environment, have been investigated. These welded pipes are fatigued due to thermal and mechanical loads caused by the cycle of cooling, heating, and internal pressure fluctuations. Residual stress measurements, weld geometry estimation, electrochemical evaluations, and metallography investigations were done as supplementary examinations. Results showed that application of ultrasonic impact treatment has led to increased fatigue life, fatigue strength, and corrosion resistance of A106-B welded steel pipes in petrochemical corrosive environment.

    The aim of this study was to examine the life expectancy of elderly people in nursing and residential care over a 20-month period and its relationship to specific risk factors. Using a retrospective cohort design, data obtained on 1888 residents placed between 1 July 1997 and 30 April 1999 in residential, nursing and dual registered homes within Nottingham Health Authority boundaries were examined. Additional data on physical and mental disability at placement were available for 514 residents. Main outcome measures comprised survival rate overall, and in relation to gender, age, home type (nursing, residential or dual), source of placement (hospital or community) and various disability factors.One-year survival rates were: overall, 66%; nursing homes, 59%; dual homes, 58%; and residential homes 76%. Median survival in nursing homes was 541 days, but was not reached in residential homes. Male gender, admission to nursing or dual registered homes, placement from hospital, decreased mobility and increased age were associated with decreased life expectancy. Although no association was found between length of survival and level of cognitive function, lack of cognitive impairment was associated with lower survival. In conclusion, mortality is high in nursing, dual and residential homes where life expectancy has been shown to be associated with gender, home type, origin of placement and mobility. Rates of survival are related to higher comorbidity and disability. Important data for planning and assessing care needs can be yielded through the analysis of mortality data. PMID:12082598

    The effects of transformational leadership and satisfaction were studied along with their interconnected effects (mediation and moderation) on commitment to change in the life insurance industry in two samples, sales managers and salespersons. A multiple mediated-moderated regression approach showed mediation and moderation to have statistically significant main effects on change commitment. Transformational leadership and satisfaction made a more important contribution to change commitment while job satisfaction had a mediating and moderating role that could enhance the relationships between leadership and change commitment. This information is of importance in building successful change commitment associations with customers.

    1998-09-01

    The aim of this study was to evaluate some aspects of care given within the preventive Child Health Services (CHS) during the first 18 months of life. A national random sample performed on child health records of 172 Swedish preschool children born between 1982 and 1987 was analysed regarding services recorded as having been provided and used within and beyond the national programme of health surveillance. Most families had made visits within the core programme of health surveillance to an optimal or at least sufficient extent. First-time parents visited the CHS more frequently than did more experienced parents. Procedures within the programme, such as growth monitoring, hip examination and immunizations, were documented to have been optimally performed on a majority of the children. Conversely, screening for hearing impairment and assessment of developmental milestones were performed less frequently, as were health information and postnatal parental education. To improve the quality of care, national recommendations ought to be more specific regarding both the performance and the documentation of the service.

    2014-06-01

    In this paper, we present the concept of feedbackability and how to identify the Minimum Feedbackability Set of an arbitrary complex directed network. Furthermore, we design an estimator and a feedback controller accessing one MFS to realize actual feedback control, i.e. control the system to our desired state according to the estimated system internal state from the output of estimator. Last but not least, we perform numerical simulations of a small linear time-invariant dynamics network and a real simple food network to verify the theoretical results. The framework presented here could make an arbitrary complex directed network realize actual feedback control and deepen our understanding of complex systems.

    Objectives This study explores the views of older adults who are receiving health and social care at the end of their lives, on how services should be funded, and describes their health-related expenditure. Design Qualitative interview study Setting North West England Participants 30 people aged 69–93 years, diagnosed with lung cancer, heart failure or stroke and judged by health professionals to be in their last year of life. Sixteen participants lived in disadvantaged areas. Main outcome measures Views of older adults on funding of services. Results Participants expressed a belief in an earned entitlement to services funded from taxation, based on a broad sense of being a good citizen. Irrespective of social background, older people felt that those who could afford to pay for social care, should do so. Sale of assets and use of children's inheritance to fund care was widely perceived as an injustice. The costs of living with illness are a burden, and families are filling many of the gaps left by welfare provision. People who had worked in low-wage occupations were most concerned to justify their current acceptance of services, and distance themselves from what they described as welfare ‘spongers’ or ‘layabouts.’ Conclusions There is a gap between the health and social care system that older adults expect and what may be provided by a reformed welfare state at a time of financial stringencies. The values that underpinned the views expressed – mutuality, care for the most needy, and the importance of working to contribute to society – are an important contribution to the debate on welfare funding.

  14. Effect of surgical masks worn concurrently over N95 filtering facepiece respirators: extended service life versus increased user burden.

    PubMed

    Roberge, Raymond J

    2008-01-01

    Growing concern over the availability of Respiratory protective devices (eg, filtering facepiece Respirators), in the face of the probable extreme demand brought on by a pandemic influenza, has prompted the suggestion that useful life of N95 filtering facepiece Respirator can be extended by the concurrent use of a surgical mask as an outer protective barrier over the Respirator. Personal protective equipment generally places a strain on the user, and the detrimental physiological and psychological burdens normally imposed by Respirator use could be magnified by the addition of an extra layer of protection such as a surgical mask. The issue of this potentially increased burden of the concurrent use of a surgical facemask with an N95 filtering facepiece Respirator is investigated to afford users the necessary information to make informed decisions Regarding the use of this Respiratory personal protective equipment in the face of large-scale outbreaks of Respiratory pathogens.

    2010-03-15

    The objectives of this study were to measure culling intervals and culling risks in the four stages of the reproductive life of female pigs and to compare culling intervals between the number of services and between herd groups, based on herd productivity. We also compared survival patterns of females pigs between these herd groups. Our data set included lifetime records of 52,792 females born between 2001 and 2004 in 101 commercial herds. Two herd groups were selected on the basis of the upper 25th percentile of pigs weaned per mated female per 5 yr between 2002 and 2006, namely the high-performing herds, and ordinary herds. Culled females were also allocated into four groups based on the stages of their reproductive life when culled: unmated gilts, mated gilts, unmated sows, and mated sows. Culling intervals in unmated gilts and mated gilts were defined as the number of days from birth to culling and from first mating to culling, respectively. Culling intervals in unmated sows and mated sows were the number of days from weaning to culling. The number of services was categorized into two groups: first service and reservice groups. Multilevel linear mixed-effects models and survival analysis were performed. Culling intervals (+/-SEM) in unmated gilts, mated gilts, unmated sows, and mated sows were 302.9+/-1.16, 98.4+/-0.92, 14.3+/-0.12, and 89.6+/-0.42 d, respectively. Culling risks in the four groups were 5.6%, 7.1%, 58.0%, and 29.3%, respectively. In unmated gilts, mated gilts, and mated sows, the culling intervals in the high-performing herds were 43.0, 18.9, and 16.0 d shorter than those in ordinary herds, respectively (P<0.05), but no difference was found between the herd groups for the culling interval of unmated sows. For mated sows in the reservice group, culling intervals of high-performing herds were >or=13.7 d shorter than those of the ordinary herds (P<0.05), but for mated sows in the first service group, there was no difference in the culling interval

    2013-04-01

    For older adults receiving long-term services and supports (LTSS), health-related quality of life (HRQoL) has emerged as a critical construct to examine because of its focus on components of well-being, which are affected by progressive changes in health status, health care, and social support. HRQoL is a health-focused quality of life (QOL) concept that encompasses aspects of QOL that affect health such as function, physical, and emotional health. Examining existing theoretical constructs and indicators of HRQoL among LTSS recipients led us to posit a revised conceptual framework for studying HRQoL among LTSS recipients. We adapted the Wilson and Cleary HRQoL model by expanding function to specifically include cognition, adding behavior and LTSS environmental characteristics in order to create a more robust HRQoL conceptual framework for older adults receiving LTSS. This refined conceptual model allows for the measurement of a mix of structural, process, and outcome measures. Continued development of a multidimensional conceptual framework with specific HRQoL measures that account for the unique characteristics of older adults receiving LTSS will contribute significantly to LTSS research, policy, and planning efforts.

    Assuming that lava flows behave as non-isothermal laminar Bingham fluids, we developed a numerical code of lava flows. We take the self gravity effects and cooling mechanisms into account. The calculation method is a kind of cellular automata using a reduced random space method, which can eliminate the mesh shape dependence. We can calculate large scale lava flows precisely without numerical instability and reproduce morphology of actual lava flows.

Spencer, Science 323, 1453 (2009)SCIEAS0036-807510.1126/science.1167782] in striking contrast to ordinary percolation. We consider a representative model which shows that the explosive percolation transition is actually a continuous, second order phase transition though with a uniquely small critical exponent of the percolation cluster size. We describe the unusual scaling properties of this transition and find its critical exponents and dimensions.

    Background Prehospital research has found little evidence in support of advanced cardiac life support (ACLS) for out‐of‐hospital cardiac arrest. However, these studies generally examine city‐based emergency medical services (EMS) systems. The training and experience of ACLS‐skilled paramedics differs internationally, and this may also contribute to negative findings. Additionally, the frequency of negative outcome in out‐of‐hospital cardiac arrest suggests that it is difficult to establish sufficient numbers to detect an effect. Purpose To examine the effect of ACLS on cardiac arrest in Queensland, Australia. Queensland has a population of 3.8 million and an area of over 1.7 million km2, and is served by a statewide EMS system, which deploys resources using a two‐tier model. Advanced treatments such as intubation and cardioactive drug administration are provided by extensively trained intensive care paramedics. Methods An observational, retrospective design was used to examine all cases of cardiac arrest attended by the Queensland Ambulance Service from January 2000 to December 2002. Logistic regression was used to examine the effect of the presence of an intensive care paramedic on survival to hospital discharge, adjusting for age, sex, initial rhythm, the presence of a witness and bystander cardiopulmonary resuscitation. Results The presence of an intensive care paramedic had a significant effect on survival (OR = 1.43, 95% CI = 1.02 to 1.99). Conclusions Highly trained ACLS‐skilled paramedics provide added survival benefit in EMS systems not optimised for early defibrillation. The reasons for this benefit are multifactorial, but may be the result of greater skill level and more informed use of the full range of prehospital interventions. PMID:17251628

    This article reports the actual participation in leisure activities by a sample of Norwegian adolescents with Down syndrome aged 14. Representing a first generation to grow up in a relatively inclusive context, they live with their families, attend mainstream schools, and are part of common community life. Leisure information was obtained in individual, structured parent interviews, and added to existing longitudinal data from a project following the sample. Generally, the leisure activity may be viewed as varying along a continuum-reaching from formal, organized, and assisted activity participation outside home, to informal, self-organized, and independent participation at home. Formal leisure activities were either organized "for all" or "adapted for disabled." The adolescents' leisure appears as active and social. However, social participation largely involved parents and family, while socializing with other adolescents mainly took place within formal activities adapted for disabled. Clearly, formal and informal activities provide rather different opportunities for social encounters and assistance. PMID:24515503

    OBJECTIVE: We adopted a sociodental approach to assess the real dental needs of Thai primary school children, and integrated an oral health-related quality of life measure (OHRQoL) into oral health service planning. We then compared the results of this sociodental assessment with standard estimates of a child's oral health needs. METHODS: We developed a new model of sociodental needs assessment and used it to assess the level of impact that various oral health conditions have on the everyday lives of school children. We then carried out a cross-sectional study of all grade-6 children (11-12 years old) in Suphan-buri Province, Thailand. We examined the sample (n = 1034) to assess the children's oral health and then we interviewed each child individually to assess what impact any dental conditions he or she may have on their quality of life. This assessment was done using an OHRQoL indicator, the Child Oral Impacts on Daily Performances index (child-OIDP). We integrated the results obtained using this indicator with those estimates obtained using more traditional, standard clinical methods, in order to generate a clearer picture of exactly which non-progressive dental conditions really needed treatment. These results take into account the impact those conditions have on the overall well-being of children and their ability to function normally and unimpeded. We were then able to prioritize their dental needs according to the severity of disruption caused in their daily lives. FINDINGS: Using standard or "normative" estimates of dental health care needs, the children's need was 98.8%. This level of need decreased signifi cantly to 39.5% when adopting the sociodental approach (P <0.001). Overall, per 100 children with a standard or normative need for dental treatment, only 40 had a sociodental need for treatment when taking into account the impact their condition has on their everyday lives. Children thus identifi ed as requiring treatment were further categorized

    University of Delaware faculty in the geological sciences, biological sciences, and the physics and astronomy departments have partnered with faculty and researchers from the school of education to form a continuum for K- 8 pre-service teacher preparation in science. The goal of the continuum is to develop integrated understandings of content and pedagogy so that these future teachers can effectively use inquiry-based approaches in teaching science in their classrooms. Throughout the continuum where earth science content appears an earth system science approach, with emphasis on inquiry-based activities, is employed. The continuum for K-8 pre-service teachers includes a gateway content course in the earth, life, or physical sciences taken during the freshman year followed by integrated science content and methods courses taken during the sophomore year. These integrated courses, called the Science Semester, were designed and implemented with funding from the National Science Foundation. During the Science Semester, traditional content and pedagogy subject matter boundaries are crossed to stress shared themes that teachers must understand to teach standards-based science. Students work collaboratively on multidisciplinary problem-based learning (PBL) activities that place science concepts in authentic contexts and build learning skills. They also critically explore the theory and practice of elementary science teaching, drawing on their shared experiences of inquiry learning during the Science Semester. The PBL activities that are the hallmark of the Science Semester provide the backdrop through which fundamental earth system interactions can be studied. For example in a PBL investigation that focuses on kids, cancer, and the environment, the hydrologic cycle with emphasis on surface runoff and ground water contamination is studied. Those students seeking secondary certification in science will enroll, as a bridge toward their student teaching experience, in an

    Gaina, A.

    The astronomical research in the Republic of Moldova after Nicolae Donitch (Donici)(1874-1956(?)) were renewed in 1957, when a satellites observations station was open in Chisinau. Fotometric observations and rotations of first Soviet artificial satellites were investigated under a program SPIN put in action by the Academy of Sciences of former Socialist Countries. The works were conducted by Assoc. prof. Dr. V. Grigorevskij, which conducted also research in variable stars. Later, at the beginning of 60-th, an astronomical Observatory at the Chisinau State University named after Lenin (actually: the State University of Moldova), placed in Lozovo-Ciuciuleni villages was open, which were coordinated by Odessa State University (Prof. V.P. Tsesevich) and the Astrosovet of the USSR. Two main groups worked in this area: first conducted by V. Grigorevskij (till 1971) and second conducted by L.I. Shakun (till 1988), both graduated from Odessa State University. Besides this research areas another astronomical observations were made: Comets observations, astroclimate and atmospheric optics in collaboration with the Institute of the Atmospheric optics of the Siberian branch of the USSR (V. Chernobai, I. Nacu, C. Usov and A.F. Poiata). Comets observations were also made since 1988 by D. I. Gorodetskij which came to Chisinau from Alma-Ata and collaborated with Ukrainean astronomers conducted by K.I. Churyumov. Another part of space research was made at the State University of Tiraspol since the beggining of 70-th by a group of teaching staff of the Tiraspol State Pedagogical University: M.D. Polanuer, V.S. Sholokhov. No a collaboration between Moldovan astronomers and Transdniestrian ones actually exist due to War in Transdniestria in 1992. An important area of research concerned the Radiophysics of the Ionosphere, which was conducted in Beltsy at the Beltsy State Pedagogical Institute by a group of teaching staff of the University since the beginning of 70-th: N.

    The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument's solar diffuser is used in its radiometric calibration for the reflective solar bands (VIS, NTR, and SWIR) ranging from 0.41 to 2.1 micron. The sun illuminates the solar diffuser either directly or through a attenuation screen. The attenuation screen consists of a regular array of pin holes. The attenuated illumination pattern on the solar diffuser is not uniform, but consists of a multitude of pin-hole images of the sun. This non-uniform illumination produces small, but noticeable radiometric effects. A description of the computer model used to simulate the effects of the attenuation screen is given and the predictions of the model are compared with actual, on-orbit, calibration measurements.

    The degenerative valvular heart disease became prioritary from the epidemiological point of view by contrast with the rheumatismal one, as a consequence of the increase of the economic standard and of average life expectancy. The calcific aortic stenosis is the most frequently encountered among the valvular heart lesions. Since the history of this disease is not well known, many efforts have been made in order to research all its aspects from the etiology to therapeutical and prophylactic methods.

  7. Caustic-Side Solvent Extraction: Prediction of Cesium Extraction for Actual Wastes and Actual Waste Simulants

    2003-02-01

    This report presents the work that followed the CSSX model development completed in FY2002. The developed cesium and potassium extraction model was based on extraction data obtained from simple aqueous media. It was tested to ensure the validity of the prediction for the cesium extraction from actual waste. Compositions of the actual tank waste were obtained from the Savannah River Site personnel and were used to prepare defined simulants and to predict cesium distribution ratios using the model. It was therefore possible to compare the cesium distribution ratios obtained from the actual waste, the simulant, and the predicted values. It was determined that the predicted values agree with the measured values for the simulants. Predicted values also agreed, with three exceptions, with measured values for the tank wastes. Discrepancies were attributed in part to the uncertainty in the cation/anion balance in the actual waste composition, but likely more so to the uncertainty in the potassium concentration in the waste, given the demonstrated large competing effect of this metal on cesium extraction. It was demonstrated that the upper limit for the potassium concentration in the feed ought to not exceed 0.05 M in order to maintain suitable cesium distribution ratios.

  11. Evaluation of an Organisational Intervention to Promote Integrated Working between Health Services and Care Homes in the Delivery of End-of-Life Care for People with Dementia: Understanding the Change Process Using a Social Identity Approach

    In the United Kingdom, approximately a third of people with dementia live in long-term care facilities for adults, the majority of whom are in the last years of life. Working arrangements between health services and care homes in England are largely ad hoc and often inequitable, yet quality end-of-life care for people with dementia in these settings requires a partnership approach to care that builds on existing practice. This paper reports on the qualitative component of a mixed method study aimed at evaluating an organisational intervention shaped by Appreciative Inquiry to promote integrated working between visiting health care practitioners (i.e. General Practitioners and District Nurses) and care home staff. The evaluation uses a social identity approach to elucidate the mechanisms of action that underlie the intervention, and understand how organisational change can be achieved. We uncovered evidence of both (i) identity mobilisation and (ii) context change, defined in theory as mechanisms to overcome divisions in healthcare. Specifically, the intervention supported integrated working across health and social care settings by (i) the development of a common group identity built on shared views and goals, but also recognition of knowledge and expertise specific to each service group which served common goals in the delivery of end-of-life care, and (ii) development of context specific practice innovations and the introduction of existing end-of-life care tools and frameworks, which could consequently be implemented as part of a meaningful bottom-up rather than top-down process. Interventions structured around a Social Identity Approach can be used to gauge the congruence of values and goals between service groups without which efforts to achieve greater integration between different health services may prove ineffectual. The strength of the approach is its ability to accommodate the diversity of service groups involved in a given area of care, by valuing their

  14. Influence of float and charge voltage adjustment on the service life of AGM VRLA batteries depending on the conditions of use

    NASA Astrophysics Data System (ADS)

    Muneret, X.; Gobé, V.; Lemoine, C.

    Valve-regulated lead-acid (VRLA) batteries with absorptive glass mat (AGM) separators have been in use for over 20 years in different standby applications. These applications are increasingly varied, especially regarding environmental conditions. Standby batteries are not only for use in applications where conditions are strictly defined and controlled (air conditioning) and it is therefore necessary to review and clarify the key parameters for the use of VRLA batteries with respect to the optimum conditions. Several series of chemical and electrochemical reactions occur in VRLA batteries particularly when in a charge or float charge condition. These reactions give specific properties such as minimal water loss (low maintenance) but also create specific precautions for use. VRLA battery functioning is limited by four main phenomena that are positive grid corrosion, irreversible active mass sulfation, active mass degradation by cycling and dry-out by loss of water. Positive grid corrosion is the usual failure mode in float operation or due to persistent overcharge. Irreversible active mass sulfation occurs due to lack of charge. In cycling, dependent upon the frequency and depth of discharge, the active mass undergoes numerous structural changes that cause degradation. These four limiting phenomena define a framework inside which several parameters determine the service life of VRLA batteries. These parameters are commissioning, temperature, and frequency and depth of discharge. Commissioning is necessary to equalise and fully charge the cells before use. Temperature, and temperature dispersion, is the main factor determining the rate of corrosion. The frequency and depth of discharge determine how the active mass is utilised. This paper, by considering these parameters both qualitatively and quantitatively, attempts to indicate how and why to adjust the charge and float voltages to optimise the use of AGM VRLA batteries according to the environmental conditions.

    Children with life limiting conditions and their families have complex needs. Evaluations must consider their views and perspectives to ensure care is relevant, appropriate and acceptable. We consulted with children, young people, their parents and local professionals to gain a more informed picture of issues affecting them prior to preparing a bid to evaluate services in the area. Multiple methods included focus groups, face-to-face and telephone interviews and participatory activities. Recordings and products from activities were analysed for content to identify areas of relevance and concern. An overarching theme from parents was ‘Why does it happen like this?’ Services did not seem designed to meet their needs. Whilst children and young people expressed ideas related to quality of environment, services and social life, professionals focused on ways of meeting the families’ needs. The theme that linked families’ concerns with those of professionals was ‘assessing individual needs’. Two questions to be addressed by the evaluation are (1) to what extent are services designed to meet the needs of children and families and (2) to what extent are children, young people and their families consulted about what they need? Consultations with families and service providers encouraged us to continue their involvement as partners in the evaluation. PMID:24270996

  17. Consequences of Predicted or Actual Asteroid Impacts

    NASA Astrophysics Data System (ADS)

    Chapman, C. R.

    2003-12-01

    Earth impact by an asteroid could have enormous physical and environmental consequences. Impactors larger than 2 km diameter could be so destructive as to threaten civilization. Since such events greatly exceed any other natural or man-made catastrophe, much extrapolation is necessary just to understand environmental implications (e.g. sudden global cooling, tsunami magnitude, toxic effects). Responses of vital elements of the ecosystem (e.g. agriculture) and of human society to such an impact are conjectural. For instance, response to the Blackout of 2003 was restrained, but response to 9/11 terrorism was arguably exaggerated and dysfunctional; would society be fragile or robust in the face of global catastrophe? Even small impacts, or predictions of impacts (accurate or faulty), could generate disproportionate responses, especially if news media reports are hyped or inaccurate or if responsible entities (e.g. military organizations in regions of conflict) are inadequately aware of the phenomenology of small impacts. Asteroid impact is the one geophysical hazard of high potential consequence with which we, fortunately, have essentially no historical experience. It is thus important that decision makers familiarize themselves with the hazard and that society (perhaps using a formal procedure, like a National Academy of Sciences study) evaluate the priority of addressing the hazard by (a) further telescopic searches for dangerous but still-undiscovered asteroids and (b) development of mitigation strategies (including deflection of an oncoming asteroid and on- Earth civil defense). I exemplify these issues by discussing several representative cases that span the range of parameters. Many of the specific physical consequences of impact involve effects like those of other geophysical disasters (flood, fire, earthquake, etc.), but the psychological and sociological aspects of predicted and actual impacts are distinctive. Standard economic cost/benefit analyses may not

  18. What works in ‘real life’ to facilitate home deaths and fewer hospital admissions for those at end of life?: results from a realist evaluation of new palliative care services in two English counties

    PubMed Central

    2014-01-01

    Background We evaluated end of life care services in two English counties including: coordination centres, telephone advice line, ‘Discharge in Reach’ nurses, a specialist community personal care team and community nurse educators. Elsewhere, we published findings detailing high family carer satisfaction and fewer hospital admissions, Accident and Emergency attendances and hospital deaths for service users compared to controls. The aim of this paper is to discuss what contributed to those outcomes. Methods Using realist evaluation, data collection included documentation (e.g. referral databases), 15 observations of services and interviews with 43 family carers and 105 professionals. Data were analysed using framework analysis, applying realist evaluation concepts. Findings were discussed at successive team meetings and further data was collected until team consensus was reached. Results Services ‘worked’ primarily for those with cancer with ‘fast track’ funding who were close to death. Factors contributing to success included services staffed with experienced palliative care professionals with dedicated (and sufficient) time for difficult conversations with family carers, patients and/or clinical colleagues about death and the practicalities of caring for the dying. Using their formal and informal knowledge of the local healthcare system, they accessed community resources to support homecare and delivered excellent services. This engendered confidence and reassurance for staff, family carers and patients, possibly contributing to less hospital admissions and A&E attendances and more home deaths. Conclusions With demand for 24-hour end of life care growing and care provision fragmented across health and social care boundaries, services like these that cut across organisational sectors may become more important. They offer an overview to help navigate those desiring a home death through the system. PMID:25075202

    Subjective feelings of actual/ideal self-discrepancy vary across individuals and influence one's own affective states. However, the neural correlates of actual/ideal self-discrepancy and their genetic individual differences remain unknown. We investigated neural correlates of actual/ideal self-discrepancy and their associations with the serotonin transporter promoter polymorphism (5-HTTLPR) that moderates human affective states during self-reflection. We scanned short/short and long/long allele carriers of 5-HTTLPR, using functional MRI, during reflection on the distance between actual and ideal self in personality traits. We found that larger actual/ideal self-discrepancy was associated with activations in the ventral/dorsal striatum and dorsal medial and lateral prefrontal cortices. Moreover, these brain activities were stronger in short/short than long/long allele carriers and predicted self-report of life satisfaction in short/short carriers but trait depression in long/long carriers. Our findings revealed neural substrates of actual/ideal self-discrepancy and their associations with affective states that are sensitive to individuals' genetic makeup.

    forward to her visits. Case managers help negotiate compliance to medication, housing, meaningful activity, substance abuse, poverty, isolation, and everything else living in the community can throw at you. Without a spouse you tend to spend a lot of time alone. One of the main reasons Marie-Claude and I moved in with each other was that neither of us was enjoying living alone. It was very romantic at first but now we are just friends who see less and less of each other. I suspect schizophrenia interferes with the quality and depth of relationships you have with other people. Amongst the people I know, schizophrenia has meant a pretty solitary life of poverty. I have a lot of acquaintances, and colleagues, but few close friends when not at work. Over the last ten years of living with schizophrenia on medication it is celibacy that has hurt the most. It saps the life out of you, your self confidence, your self esteem. In some Scandinavian countries and Holland disabled people are allowed monthly visits by state approved sex workers. To me that is only common sense. To live without sex is unnatural and can only cause emotional suffering. We don't recognize the importance of quality sexual experience in keeping people healthy and happy in France. That doesn't mean it isn't I have a pretty high profile in my community through the meaningful activity I do. From having a half dozen names and faces to remember, I now have what seems like hundreds. I have a lot of trouble remembering people's names and faces. I am still meeting new people but I'm rarely invited to socialize with any after work. They have families, full time jobs, kids, cars, cottages, etc. My life at home is pretty solitary. It's a nuisance to travel across the city to visit people. There are few people that I share a similar background with. Since people with schizophrenia tend to have trouble learning new things, and change very little as a result, we tend to have trouble making new friends. People with

    The phrase 'quality of life' is actually misleading. The designation suggests that the issue has to do with 1 quality, whereas in fact more qualities of life are indicated. Four of these qualities are: 1. the 'livability' of the surroundings, 2. the 'life-abilities' of the individual, 3. the 'utility of life' and 4. the subjective 'satisfaction' with a person's own life. The various qualities cannot meaningfully be collected together in an index. The most comprehensive measure of quality of life is how long and happily a person lives. The relationship between that and oral health has still hardly been studied.

  5. Life extensions of existing power plants -- Assessment and monitoring with personal computer

    Koch, J.; Kaminski, T.

    1998-07-01

    In many industrial countries of the World the marginal conditions for the construction and use of fossil-fired power plants changed. Location problems as well as lengthy and protracted permitting procedures for new plants revealed the need for a method for the extension of the service life of existing plants. Owner of power plants show interest in operating their power plants units for 15--25 years exceeding their design period. Thus a service life assessment including the investigation of the steps necessary for NO{sub x} reduction and desulfurization certainly shows service life extension is an alternative to the construction of a new power plant. Moreover, this investigation can increase the plant reliability. For the life extension of a power plant at first the assessment of the actual condition is of importance. The components relevant for the service life are selected from such parts which are subjected e.g. to weathering, wear, temperatures above 450 C and alternating expansion stresses taking into account the present operating loads and experiences. Generally, the components to be considered critical have to be subjected to a special test. Their actual condition is determined in detail by means of check calculation and tests. For the inspection of creep-stressed components first a check calculation of the components is carried out. It has to be admitted that these calculations, however, can have a certain degree of inaccuracy due to various criteria which can be determined partly by tests. To minimize the above mentioned uncertainties to a large extent one is forced to thread other paths to obtain information about the actual condition of the component. An important measure is the visual check of the components and non destructive tests.

  6. The use of long term monitoring data for the extension of the service duration of existing wind turbine support structures

    Loraux, C.; Brühwiler, E.

    2016-09-01

    Actual wind energy converter (WEC) are designed for a relatively short service life of 20 years and the limiting criterion is the fatigue safety. However, effective fatigue loading endured by the structural components of the wind turbines (WT) is likely to be much below design assumptions provided by current codes. This paper describes a simple but efficient long term monitoring system that allows owners to verify the fatigue safety of their existing WTs. The monitored data will also help to drastically extend the service life of existing wind turbine support structure and will thus reduce the global environmental footprint of WTs.

    2008-07-01

    This laboratory study examined differential effects of television broadcasts of terrorism on viewers' anxiety according to their actual exposure history, and differential efficacy of a preparatory intervention in moderating elevated anxiety for high or low actual exposure. Participants were 80 young Israeli adults, randomly allocated to a terrorism or non-terrorism media broadcast, and for each type of exposure, to a preparatory or control intervention. Actual political violence and terrorism exposure history was assessed, and anxiety measured explicitly and indirectly prior and subsequent to the intervention and media exposure manipulation. Results showed that in the terrorism media exposure, participants with high more than low actual political life events (PLE) exposure showed higher post-test levels of indirectly measured anxiety. Clinical intervention before the terrorism media exposure moderated indirectly measured anxiety among participants with high PLE exposure, but increased anxiety for low PLE. Findings outline preparatory measures that could maximize coping for the high PLE actual exposure at-risk sector.

    Poverty and youth unemployment are critical issues in South Africa with homeless persons begging at traffic light intersections in all major cities. Support services represent one way of empowering homeless youth. The study therefore examined the experiences of 10 homeless young adult males in Hillbrow, Johannesburg and whether they were aware of local health and social services. Qualitative interviews revealed that participants experienced poor health, addiction, physical violence, psychological trauma, and public hostility. Despite limited education, they were aware of and utilized local health and social services. Findings are discussed in terms of their implications for social work.

    Objectives. We examined the use rates and correlates of formal psychiatric services among the US-born and immigrant Caribbean Black population. Methods. We compared overall mental health service use in samples of Caribbean Blacks and African Americans and examined the within-sample ethnic variation among Caribbean Blacks, including for ethnic origin (Spanish Caribbean, Haiti, and English Caribbean), nativity status (those born in or outside the United States), number of years spent living in the United States, age at the time of immigration, and generational status. Results. African Americans and Caribbean Blacks used formal mental health care services at relatively low rates. Among Caribbean Blacks, generational status and nativity showed the greatest effects on rates of reported use, satisfaction, and perceived helpfulness. Of those study participants who met the criteria for disorders as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, about one third used formal mental health care services. The US-born subjects were more likely to receive care than were first-generation immigrants. Conclusions. Our study underscores the importance of ethnicity, immigration, and migration-related factors, within racial categorization, as it pertains to the use of mental health services in the United States. Our findings suggest that timing of migration and generational status of Caribbean Black immigrants and ancestry groups contribute to important differences in rates and sources of use, relative satisfaction, and perception of helpfulness, with regard to formal mental health services.

    The relationship between perceived and actual motor competence was examined among college students. Participants were 114 college students (55 men, 59 women; M age = 22.3 yr., SD = 3.9). All participants completed a short survey on perception of motor competence in basketball and took a Control Basketball Dribble Test to assess their actual motor skill. Perceived motor competence in basketball was significantly related to basketball dribbling performance. Given the positive relationship between actual motor competence and perceived competence, enhancing an individual's actual motor competence may contribute to their perceived competence, which may improve an individual's physical activity participation.

    Mental health service utilization several years following a man-made or natural disaster can be lower than expected, despite a high prevalence of mental health disorders among those exposed. This study focused on factors associated with subjective unmet mental health care need (UMHCN) and its relationship to a combination of diagnostic history and current mental health symptoms, 5-6 years after the 9-11-01 World Trade Center (WTC) disaster in New York City, USA. Two survey waves of the WTC Health Registry, after exclusions, provided a sample of 36,625 enrollees for this analysis. Important differences were found among enrollees who were categorized according to the presence or absence of a self-reported mental health diagnosis and symptoms indicative of post-traumatic stress disorder or serious psychological distress. Persons with diagnoses and symptoms had the highest levels of UMHCN, poor mental health days, and mental health service use. Those with symptoms only were a vulnerable group much less likely to use mental health services yet reporting UMHCN and poor mental health days. Implications for delivering mental health services include recognizing that many persons with undiagnosed but symptomatic mental health symptoms are not using mental health services, despite having perceived need for mental health care.

  10. Thermostabilized Shelf Life Study

    NASA Technical Reports Server (NTRS)

    Perchonok, Michele H.; Catauro, Patricia M.

    2009-01-01

    The objective of this project is to determine the shelf life end-point of various food items by means of actual measurement or mathematical projection. The primary goal of the Advanced Food Technology Project in these long duration exploratory missions is to provide the crew with a palatable, nutritious and safe food system while minimizing volume, mass, and waste. The Mars missions could be as long as 2.5 years with the potential of the food being positioned prior to the crew arrival. Therefore, it is anticipated that foods that are used during the Mars missions will require a 5 year shelf life. Shelf life criteria are safety, nutrition, and acceptability. Any of these criteria can be the limiting factor in determining the food's shelf life. Due to the heat sterilization process used for the thermostabilized food items, safety will be preserved as long as the integrity of the package is maintained. Nutrition and acceptability will change over time. Since the food can be the sole source of nutrition to the crew, a significant loss in nutrition may determine when the shelf life endpoint has occurred. Shelf life can be defined when the food item is no longer acceptable. Acceptability can be defined in terms of appearance, flavor, texture, or aroma. Results from shelf life studies of the thermostabilized food items suggest that the shelf life of the foods range from 0 months to 8 years, depending on formulation.

    The de Bruijn diagram describing those decompositions of the neighborhoods of a one dimensional cellular automaton which conform to predetermined requirements of periodicity and translational symmetry shows how to construct extended configurations satisfying the same requirements. Similar diagrams, formed by stages, describe higher dimensional automata, although they become more laborious to compute with increasing neighborhood size. The procedure is illustrated by computing some still lifes for Conway's game of Life, a widely known two dimensional cellular automaton. This paper is written in September 10, 1988.

    Safety of patients is actual problem of up-to-date medicine. The current successful treatment of various sicknesses is achieved by implementation in clinical practice such medical preparations (medications), which are characterized with the high therapeutic activity, low toxicity and prolonged effects. In spite of evidence of the pharmacotherapeutical advances, the frequency of complications after medication has grown - that is why the safety of patients is the acute actual problem of medicine and ecological state of human population today.

  5. On the power of autobiographical memories: from threat and challenge appraisals to actual behaviour.

    Autobiographical memories are a major feature of mental life in humans. However, research on the influence of autobiographical recall on actual behaviour is scarce. We predicted and found that general memories of failure and specific memories of success resulted in worse performance than general memories of success and specific memories of failure. This performance pattern was mediated by task appraisal, suggesting that autobiographical memories (of failure and success) impact performance by shaping the perception of the upcoming task. Combined with the fact that these effects occurred even when the content of autobiographical memories was unrelated to the upcoming task, the present research represents an important step forward in understanding how autobiographical recall influences actual behaviour.

    Two computational models to determine the fatigue life and reliability of a commercial turboprop gearbox are compared with each other and with field data. These models are (1) Monte Carlo simulation of randomly selected lives of individual bearings and gears comprising the system and (2) two-parameter Weibull distribution function for bearings and gears comprising the system using strict-series system reliability to combine the calculated individual component lives in the gearbox. The Monte Carlo simulation included the virtual testing of 744,450 gearboxes. Two sets of field data were obtained from 64 gearboxes that were first-run to removal for cause, were refurbished and placed back in service, and then were second-run until removal for cause. A series of equations were empirically developed from the Monte Carlo simulation to determine the statistical variation in predicted life and Weibull slope as a function of the number of gearboxes failed. The resultant L(sub 10) life from the field data was 5,627 hr. From strict-series system reliability, the predicted L(sub 10) life was 774 hr. From the Monte Carlo simulation, the median value for the L(sub 10) gearbox lives equaled 757 hr. Half of the gearbox L(sub 10) lives will be less than this value and the other half more. The resultant L(sub 10) life of the second-run (refurbished) gearboxes was 1,334 hr. The apparent load-life exponent p for the roller bearings is 5.2. Were the bearing lives to be recalculated with a load-life exponent p equal to 5.2, the predicted L(sub 10) life of the gearbox would be equal to the actual life obtained in the field. The component failure distribution of the gearbox from the Monte Carlo simulation was nearly identical to that using the strict-series system reliability analysis, proving the compatibility of these methods.

  7. An Aristotelian Account of Minimal Chemical Life

    2010-12-01

    This paper addresses the open philosophical and scientific problem of explaining and defining life. This problem is controversial, and there is nothing approaching a consensus about what life is. This raises a philosophical meta-question: Why is life so controversial and so difficult to define? This paper proposes that we can attribute a significant part of the controversy over life to use of a Cartesian approach to explaining life, which seeks necessary and sufficient conditions for being an individual living organism, out of the context of other organisms and the abiotic environment. The Cartesian approach contrasts with an Aristotelian approach to explaining life, which considers life only in the whole context in which it actually exists, looks at the characteristic phenomena involving actual life, and seeks the deepest and most unified explanation for those phenomena. The phenomena of life might be difficult to delimit precisely, but it certainly includes life's characteristic hallmarks, borderline cases, and puzzles. The Program-Metabolism-Container (PMC) model construes minimal chemical life as a functionally integrated triad of chemical systems, which are identified as the Program, Metabolism, and Container. Rasmussen diagrams precisely depict the functional definition of minimal chemical life. The PMC model illustrates the Aristotelian approach to life, because it explains eight of life's hallmarks, one of life's borderline cases (the virus), and two of life's puzzles.

    The purpose of this study was to examine the relationship between children's actual and perceived motor competence. 280 children between the ages of 10 and 13 years individually completed the Children's Physical Self-perception Profile which assesses perceptions of sport competence, physical conditioning, strength, body attractiveness, and general physical self-worth. The internal reliabilities (a) of the subscales ranged from .75 to .82. After completing the profile, the subject's actual motor competence was measured using tests of aerobic fitness and functional strength. Body fatness (sum of five skinfolds) was measured as an objective measure of perceived body attractiveness. Analysis of variance showed that boys and girls differed in perceived competence and actual motor competence. The boys showed higher perceived competence on four scores, but there was no sex difference in perception of body attractiveness. Correlations and regression analysis showed that actual and perceived motor competence were significantly but only moderately (r =.25-.56) correlated. In addition, items of perceived physical competence and age accounted for 17% (sit-ups) to 25% (endurance shuttle run) of the variance in actual motor competence of the children. These findings showed that 10- to 13-yr-old children can only moderately assess personal motor competence. PMID:12186225

    Newly emerging health technologies are being developed to care for children with complex cardiac defects. Neurodevelopmental and childhood school-related outcomes are of great interest to parents of children receiving this care, care providers, and healthcare administrators. Since the 1970s, neonatal follow-up clinics have provided service, audit, and research for preterm infants as care for these at-risk children evolved. We have chosen to present for this issue the mechanism for longitudinal follow-up of survivors that we have developed for western Canada patterned after neonatal follow-up. Our program provides registration for young children receiving complex cardiac surgery, heart transplantation, ventricular assist device support, and extracorporeal life support among others. The program includes multidisciplinary assessments with appropriate neurodevelopmental intervention, active quality improvement evaluations, and outcomes research. Through this mechanism, consistently high (96%) follow-up over two years is maintained. PMID:21629801

  12. Taking human life.

    PubMed

    Brock, Dan W

    1985-07-01

    Alan Donagan's position regarding the morality of taking innocent human life, that it is impermissible regardless of the wishes of the victim, is criticized by Brock who argues for a rights-based alternative. His argument appeals to the nature of persons' actual interest in life and gives them an additional element of control which they lack if a nonwaivable moral duty not to kill prevails. The author rejects Donagan's view that stopping a life-sustaining treatment, even when a competent patient has consented, is morally wrong and that there is no moral difference between killing and allowing to die. A rights-based position permits stopping treatment of incompetent patients based on what the patient would have wanted or what is in his or her best interest, and allows the withholding of treatment from a terminally ill person, with the patient's consent and for a benevolent motive, to be evaluated as morally different from killing that patient.

  13. Shame amplifies the association between stressful life events and paranoia amongst young adults using mental health services: Implications for understanding risk and psychological resilience.

    Shame is associated with a range of psychological disorders, and is a trans-diagnostic moderator of the association between stressors and symptoms of disorder. However, research has yet to investigate shame in relation to specific psychotic symptoms in clinical groups. In order to address this, the present study investigated shame in young adults with mental health problems, to test whether shame was i) directly associated with paranoia, a prevalent psychotic symptom, and ii) a moderator of the association between stress and paranoia. Sixty participants completed measures of stressful events, paranoia, shame, depression and anxiety. Results from a cross-sectional regression analysis suggested that shame was associated with paranoia after the stressful life event measure was entered into the model, and shame moderated the association between stress and paranoia. For individuals scoring high on shame, shame amplified the association between stress and paranoia, but for low-shame individuals, the association between stress and paranoia was non-significant. These findings suggest that high levels of shame could confer vulnerability for paranoia amongst clinical groups, and that resistance to experiencing shame could be a marker of resilience.

    Early life stress (ELS) may induce long-lasting psychological complications in adulthood. The protective role of resilience against the development of psychopathology is also important. The purpose of this study was to investigate the relationships among ELS, resilience, depression, anxiety, and aggression in young adults. Four hundred sixty-one army inductees gave written informed consent and participated in this study. We assessed psychopathology using the Korea Military Personality Test, ELS using the Childhood Abuse Experience Scale, and resilience with the resilience scale. Analyses of variance, correlation analyses, and hierarchical multiple linear regression analyses were conducted for statistical analyses. The regression model explained 35.8%, 41.0%, and 23.3% of the total variance in the depression, anxiety, and aggression indices, respectively. We can find that even though ELS experience is positively associated with depression, anxiety, and aggression, resilience may have significant attenuating effect against the ELS effect on severity of these psychopathologies. Emotion regulation showed the most beneficial effect among resilience factors on reducing severity of psychopathologies. To improve mental health for young adults, ELS assessment and resilience enhancement program should be considered. PMID:26539013

[Subjects and Methods] In the present study, 52 university students in their 20s (26 males, 26 females) were selected in order to analyze the activity of five lower extremity muscles (vastus lateralis, rectus femoris, vastus medialis, tibialis anterior, and gastrocnemius). The selected subjects had sufficient muscle strength for the experiment and normal joint range of motion. [Results] To examine the sociodemographic variables of the study subjects, the frequencies and percentages of individual items were presented as follows Table 3. [Conclusion] Differences in lower extremity muscle activity levels during standing and sitting were identified, and differences between genders were also seen. There was no significant difference in lower extremity muscle activity levels between use of fixed and wheeled chairs. PMID:27065547

    Operations under single pilot instrument flight rules for general aviation aircraft is known to be one of the most demanding pilot tasks. Scanning numerous instruments plays a key role for perception and decision-making during flight. Flight experiments have been done by a single engine light airplane to investigate the pilot eye scanning technique for IFR flights. Comparisons between the results by an actual flight and those by a PC-based flight simulator are made. The experimental difficulties of pilot eye scanning measurements during the actual IFR flight are discussed.

    This paper concerns the efficacy of meditation and relaxation in promoting self-actualization and changes in self-reported stress among 62 college students. Two groups were given mantra meditation and a yogic relaxation technique referred to as Shavasana. Pre- and posttest measures were taken on the Personal Orientation Inventory and the Behavioral Relaxation Scale. Both groups showed significant increases in scores on self-actualization; however, no differences were found between groups. Meditation training was associated with larger gains in scores on measures of systematic relaxed behavior than of the relaxation training.

    Prior to the development of the NASA experimental wind shear radar system, extensive computer simulations were conducted to determine the performance of the radar in combined weather and ground clutter environments. The simulation of the radar used analytical microburst models to determine weather returns and synthetic aperture radar (SAR) maps to determine ground clutter returns. These simulations were used to guide the development of hazard detection algorithms and to predict their performance. The structure of the radar simulation is reviewed. Actual flight data results from the Orlando and Denver tests are compared with simulated results. Areas of agreement and disagreement of actual and simulated results are shown.

  2. How Are Mate Preferences Linked with Actual Mate Selection? Tests of Mate Preference Integration Algorithms Using Computer Simulations and Actual Mating Couples

    2016-01-01

    Prior mate preference research has focused on the content of mate preferences. Yet in real life, people must select mates among potentials who vary along myriad dimensions. How do people incorporate information on many different mate preferences in order to choose which partner to pursue? Here, in Study 1, we compare seven candidate algorithms for integrating multiple mate preferences in a competitive agent-based model of human mate choice evolution. This model shows that a Euclidean algorithm is the most evolvable solution to the problem of selecting fitness-beneficial mates. Next, across three studies of actual couples (Study 2: n = 214; Study 3: n = 259; Study 4: n = 294) we apply the Euclidean algorithm toward predicting mate preference fulfillment overall and preference fulfillment as a function of mate value. Consistent with the hypothesis that mate preferences are integrated according to a Euclidean algorithm, we find that actual mates lie close in multidimensional preference space to the preferences of their partners. Moreover, this Euclidean preference fulfillment is greater for people who are higher in mate value, highlighting theoretically-predictable individual differences in who gets what they want. These new Euclidean tools have important implications for understanding real-world dynamics of mate selection. PMID:27276030

    The EMBRACE (European Model for Bioinformatics Research and Community Education) web service collection is the culmination of a 5-year project that set out to investigate issues involved in developing and deploying web services for use in the life sciences. The project concluded that in order for web services to achieve widespread adoption, standards must be defined for the choice of web service technology, for semantically annotating both service function and the data exchanged, and a mechanism for discovering services must be provided. Building on this, the project developed: EDAM, an ontology for describing life science web services; BioXSD, a schema for exchanging data between services; and a centralized registry (http://www.embraceregistry.net) that collects together around 1000 services developed by the consortium partners. This article presents the current status of the collection and its associated recommendations and standards definitions. PMID:20462862

The actual strains incurred at the root of a discontinuity in cyclically loaded test samples subjected to inelastic deformation at high temperature where creep deformations readily occur were determined. The steady state cyclic, stress-strain response at the root of the discontinuity was analyzed. Flat, double notched uniaxially loaded fatigue specimens manufactured from the nickel base, superalloy Inconel 718 were used. The ISDG was used to obtain cycle by cycle recordings of notch root strain during continuous and hold time cycling at 649 C. Comparisons to Neuber and finite element model analyses were made. The results obtained provide a benchmark data set in high technology design where notch fatigue life is the predominant component service life limitation.

    I shall present three arguments for the proposition that intelligent life is very rare in the universe. First, I shall summarize the consensus opinion of the founders of the modern synthesis (Simpson, Dobzhanski and Mayr) that the evolution of intelligent life is exceedingly improbable. Secondly, I shall develop the Fermi paradox: if they existed, they would be here. Thirdly, I shall show that if intelligent life were too common, it would use up all available resources and die out. But I shall show that the quantum mechanical principle of unitarity (actually a form of teleology!) requires intelligent life to survive to the end of time. Finally, I shall argue that, if the universe is indeed accelerating, then survival to the end of time requires that intelligent life, though rare, to have evolved several times in the visible universe. I shall argue that the acceleration is a consequence of the excess of matter over antimatter in the universe. I shall suggest experiments to test these claims.

    The Actual Curriculum Development Practices Instrument (ACDP-I) was developed and the factorial validity of the ACDP-I was tested (n = 107) using exploratory factor analysis procedures in the earlier work of [1]. Despite the ACDP-I appears to be content and construct valid instrument with very high internal reliability qualities for using in Malaysia, the accumulated evidences are still needed to provide a sound scientific basis for the proposed score interpretations. Therefore, the present study addresses this concern by utilising the confirmatory factor analysis to further confirm the theoretical structure of the variable Actual Curriculum Development Practices (ACDP) and enrich the psychometrical properties of ACDP-I. Results of this study have practical implication to both researchers and educators whose concerns focus on teachers' classroom practices and the instrument development and validation process.

    This study addressed how healthcare clinics perceive themselves in regard to accessibility for persons with spinal cord injuries (SCI). All 40 of the clinics surveyed reported that they were wheelchair accessible; however, there was significant variability in the number of sites that actually met the guidelines of the Americans with Disability Act. In general, a person using a wheelchair could enter the building, the examination room, and the bathroom. The majority of sites did not have an examination table that could be lowered to wheelchair level. Most reported limited experience in working with persons with (SCI), yet they claimed to be able to assist with difficult transfers. Only one site knew about autonomic dysreflexia. Problems of accessibility appeared to be seriously compounded by the clinics' perception of how they met physical accessibility guidelines without consideration of the actual needs of persons with SCI. This study addressed the perception of accessibility as reported by clinic managers versus actual accessibility in healthcare clinics in a Midwestern metropolitan area for persons using wheelchairs.

    This study provides an overview of the research performance of major European countries in the field Oncology, the most important journals in which they published their research articles, and the most important academic institutions publishing them. The analysis was based on Thomson Scientific's Web of Science (WoS) and calculated bibliometric indicators of publication activity and actual citation impact. Studying the time period 2000-2006, it gives an update of earlier studies, but at the same time it expands their methodologies, using a broader definition of the field, calculating indicators of actual citation impact, and analysing new and policy relevant aspects. Findings suggest that the emergence of Asian countries in the field Oncology has displaced European articles more strongly than articles from the USA; that oncologists who have published their articles in important, more general journals or in journals covering other specialties, rather than in their own specialist journals, have generated a relatively high actual citation impact; and that universities from Germany, and--to a lesser extent--those from Italy, the Netherlands, UK, and Sweden, dominate a ranking of European universities based on number of articles in oncology. The outcomes illustrate that different bibliometric methodologies may lead to different outcomes, and that outcomes should be interpreted with care.

    This laboratory study examined differential effects of television broadcasts of terrorism on viewers' anxiety according to their actual exposure history, and differential efficacy of a preparatory intervention in moderating elevated anxiety for high or low actual exposure. Participants were 80 young Israeli adults, randomly allocated to a terrorism or non-terrorism media broadcast, and for each type of exposure, to a preparatory or control intervention. Actual political violence and terrorism exposure history was assessed, and anxiety measured explicitly and indirectly prior and subsequent to the intervention and media exposure manipulation. Results showed that in the terrorism media exposure, participants with high more than low actual political life events (PLE) exposure showed higher post-test levels of indirectly measured anxiety. Clinical intervention before the terrorism media exposure moderated indirectly measured anxiety among participants with high PLE exposure, but increased anxiety for low PLE. Findings outline preparatory measures that could maximize coping for the high PLE actual exposure at-risk sector. PMID:18938291

    2003-12-01

    In the Danish Quality of Life Survey, we asked 10,000 people about their quality of life with the validated SEQOL questionnaire with more than 300 questions on their quality of life. How did they feel? How content were they with their lives? How happy were they? Did they feel their needs were fulfilled? And many more questions. We asked the questions we believed to be important for their quality of life (QOL). The results were quite surprising and forced us to recontemplate the following philosophical questions: What is quality of life, happiness, and meaning in life? What is a human being? Do we need a new biology? Is the brain the seat of consciousness? How do we seize the meaning of life and by doing so, will we become well again? What are the key concepts of quality of life? The meaning of life is connectedness and development. It is about realizing every opportunity and potential in one"s existence. The opportunities must be found and acknowledged. What do you find when you find yourself deep down? You find your real self and your purpose in life. You realize that you are already a part of a larger totality. Antonovsky called it "coherence". Maslow called it "transcendence". Frankl called it "meaning of life". We call it simply "being". To test if these philosophical questions are actually relevant for medicine, we looked at the consequences for patients being taught the quality of life philosophy. Quite surprisingly we learned from our pilot studies with "quality of life as medicine" that just by assimilating the basic concepts of the quality of life philosophy presented in this series of papers, patients felt better and saw their lives as more meaningful. The improvement of the patient"s personal philosophy of life seems to be the essence of holistic medicine, helping the patient to assume more responsibility for his or her own existence.

    Context Treatment satisfaction with a loading phase of monthly injections for 3 months followed by a pro-re-nata regimen of ranibizumab in neovascular age-related macular degeneration (nAMD) remains unclear. Aims The aim was to evaluate the treatment satisfaction of persons with nAMD treated with ranibizumab in a real-life setting. Settings and design A cross-sectional study was conducted across three eye clinics within the National Health Service in the UK, where treatment is provided free at point of contact. Materials and methods A total of 250 patients were selected randomly for the study. Treatment satisfaction was assessed using the Macular Treatment Satisfaction Questionnaire. Data were collected on satisfaction of the service provided (Client Service Questionnaire-8) and the patients’ demographic and quality of life and treatment history. Factors governing treatment questionnaire were determined. Results The most important factors that determined the satisfaction were the service provided at the clinic (Client Service Questionnaire-8), health-related quality of life (EQ-5D-3L), and duration of AMD. Visual acuity changes were rated as less important than one would have expected. Conclusion The study result suggested that treatment satisfaction for nAMD was governed by the perception of being reviewed and injected regularly over a long period of time than the actual change in visual acuity from the treatment.

    South-East Asia (i.e. Indonesia) has enjoyed economic boom and rapid unbridled growth for the last decade. This rapid expansion was fuelled by cheap labour, foreign and local investments and the extensive development of the oil and non-oil sector. Dark clouds, however, loomed on the economic and financial horizons of these rapidly developing 'tiger' economies. Indonesia was not only affected by various facts-of-life elements which contributed to these grave forecasts but also by a wave of natural disasters on an unprecedented scale, with devastating social and economic effects on the poor and susceptible groups. Although economic recovery will take time, the most pressing and practical measure remains the need to create a health and social safety net to maintain the health, social and nutritional status of the "population-at-risk". This paper is an exposure of "lessons learnt" and the invaluable role of health services and public health to the negative impact of the monetary crisis experienced by various inter-sectors, which the authors believe can be used as a long-term investment measure in other countries.

    Studies into social networks show that relationships have a significant impact on people's lives. When associated with the population suffering from mental disorders, they serve as an important protection factor and a manager of resources and social support. However, studies show that people with mental disorders have impoverished social networks and few significant relationships. In this perspective, this research sought to characterize the social networks of users of NAPS II in Santo André (SP, Brazil). Conducted in 2006, the qualitative research adopted an ethnographic approach and used interviews by topics, participant observation and field notes. The results revealed that the group studied had an impoverished social network; the life histories of the subjects is related to this impoverishment, since the disruptions caused by situations of crisis or institutionalization removed them from the network of relationships, placing them in a situation of social vulnerability. An attempt was made to address the importance of intervention in the relationships and the role of the services in this process.

    1984-01-01

    Hot-section gas-turbine components typically require some form of coating for oxidation and corrosion protection. Efficient use of coatings requires reliable and accurate predictions of the protective life of the coating. Currently engine inspections and component replacements are often made on a conservative basis. As a result, there is a constant need to improve and develop the life-prediction capability of metallic coatings for use in various service environments. The purpose of this present work is aimed at developing of an improved methodology for predicting metallic coating lives in an oxidizing environment and in a corrosive environment.

    By using software ArcGIS 9.2, an evaluation model was established to simulate the ecosystem service of Ertan Reservoir watershed in mitigating the sand sedimentation in the reservoir. In the meantime, sediment delivery ratio and universal soil loss equation were used to simulate the spatial patterns of the annual sediment yield and sediment retention in the watershed as well as the value during the service life period. In 2000, the total quantity of soil retention in the watershed was 12. 1 x 10(8) t x a(-1). The region with higher soil retention was near the main and branch streams of Yalong River, and that with higher sediment delivery ratio was near the streams and the Ertan Reservoir. The region with higher sediment yield and sediment retention was around the reservoir. The actual sediment yield in the study area was 629.3 x 10(4) t x a(-1), occupying 12.7% of the actual soil erosion volume. Farmland was the most important source of sediment yield, with its sediment yield occupying 62.9% of the total. The contribution of forestland to the mitigation of reservoir sand sedimentation was higher than that of the other lands on a per unit area basis. For the reservoir's designed operating life (100 a), the total value of the watershed in the service of mitigating Ertan Reservoir sand sedimentation was 2.75 billion yuan.

    The authors have researched multimedia system and support system for nursing studies on and practices of reminiscence therapy and life review therapy. The concept of the life review is presented by Butler in 1963. The process of thinking back on one's life and communicating about one's life to another person is called life review. There is a famous episode concerning the memory. It is called as Proustian effects. This effect is mentioned on the Proust's novel as an episode that a story teller reminds his old memory when he dipped a madeleine in tea. So many scientists research why smells trigger the memory. The authors pay attention to the relation between smells and memory although the reason is not evident yet. Then we have tried to add an olfactory display to the multimedia system so that the smells become a trigger of reminding buried memories. An olfactory display is a device that delivers smells to the nose. It provides us with special effects, for example to emit smell as if you were there or to give a trigger for reminding us of memories. The authors have developed a tabletop display system connected with the olfactory display. For delivering a flavor to user's nose, the system needs to recognition and measure positions of user's face and nose. In this paper, the authors describe an olfactory display which enables to detect the nose position for an effective delivery.

    The number of partial contact surfaces of a brush-ring contact is measured by means of a statistical method. The particular brush is fitted with wicks - that is, insulated and cemented cylinders of brush material, terminating in the brush surface. The number of partial contact surfaces can be computed from the length of the rest periods in which such wicks remain without current. Resistance measurements enable the determination of the size of the contact surfaces. The pressure in the actual contact surface of a recently bedded brush is found to be not much lower than the Brinell hardness of the brush.

    Similar to photovoltaic (PV) and fuel cells, thermoelectric generators (TEGs) supply direct-current (DC) power, essentially requiring DC/alternating current (AC) conversion for delivery as electricity into the grid network. Use of PVs is already well established through power conditioning systems (PCSs) that enable DC/AC conversion with maximum-power-point tracking, which enables commercial use by customers. From the economic, legal, and regulatory perspectives, a commercial PCS for PVs should also be available for TEGs, preferably as is or with just simple adjustment. Herein, we report use of a PV PCS with an actual TEG. The results are analyzed, and proper application for TEGs is proposed.

    2004-08-01

    Dieting has developed a negative reputation among many researchers and health care professionals. However, 'dieting' can refer to a variety of behavioural patterns that are associated with different effects on eating and body weight. The wisdom of dieting depends on what kind of dieting is involved, who is doing it, and why. Thus, depending on what one means by the term, dieting can be quite harmful, merely ineffective or actually beneficial. The present paper considers examples of all three. In particular, we argue that judgements about the desirability of dieting should consider the likely consequences to particular individuals of engaging in, or not engaging in, dieting behaviour.

    This paper illustrates a complete inspection, testing, and maintenance program implemented at PECO Energy`s Peach Bottom Atomic Power Station (PBAPS). Concerns that tubes may have been too conservatively plugged due to insufficient data justified a program that included: removal of previously installed plugs; videoprobe inspection of failed areas; extraction of tube samples for further analysis; eddy current testing of selected tubes; evaluation of the condition of insurance plugged tubes for return to service; hydrostatic testing of selected tubes; final repair plan based on the results of the above program. This paper concludes that no single method of inspection or testing should be solely relied upon in establishing: the extent of actual degraded conditions; the source(s) of failure mechanisms; and the details of repair. It is a combination of all gathered data that affords the best chance in arresting problems and optimizing feedwater heater life.

    The health of mothers is a critical element in the health of families. All activities within the WHO Division of Family Health, such as family planning, child health and development are very closely related to the whole issue of safe motherhood and women's reproductive health. The Director of WHO's Division of Family Health identifies WHO's priorities for the Maternal Health and Safe Motherhood Program in response to questions on the importance and priorities of safe motherhood in the overall work of WHO's Division of Family Health and on the needs of countries with high maternal mortality. WHO and its partners in the Safe Motherhood Initiative have done an enormous amount of work in alerting the world, particularly policymakers, to the problem of maternal mortality. However, WHO and the Safe Motherhood Initiative need to be more active at the country level, since countries need help in developing and implementing programs, and need to monitor and evaluate their effectiveness in improving maternal health. They also need a set of tools to identify, quantify, and deal with the weaknesses in maternal health care. In this way they will be able to continue to ensure safe delivery and safe motherhood.

  7. Probabilistic Study Conducted on Sensor-Based Engine Life Calculation

    2004-01-01

    Turbine engine life management is a very complicated process to ensure the safe operation of an engine subjected to complex usage. The challenge of life management is to find a reasonable compromise between the safe operation and the maximum usage of critical parts to reduce maintenance costs. The commonly used "cycle count" approach does not take the engine operation conditions into account, and it oversimplifies the calculation of the life usage. Because of the shortcomings, many engine components are regularly pulled for maintenance before their usable life is over. And, if an engine has been running regularly under more severe conditions, components might not be taken out of service before they exceed their designed risk of failure. The NASA Glenn Research Center and its industrial and academic partners have been using measurable parameters to improve engine life estimation. This study was based on the Monte Carlo simulation of 5000 typical flights under various operating conditions. First a closed-loop engine model was developed to simulate the engine operation across the mission profile and a thermomechanical fatigue (TMF) damage model was used to calculate the actual damage during takeoff, where the maximum TMF accumulates. Next, a Weibull distribution was used to estimate the implied probability of failure for a given accumulated cycle count. Monte Carlo simulations were then employed to find the profiles of the TMF damage under different operating assumptions including parameter uncertainties. Finally, probabilities of failure for different operating conditions were analyzed to demonstrate the importance of a sensor-based damage calculation in order to better manage the risk of failure and on-wing life.

  9. What do tests of formal reasoning actually measure?

    NASA Astrophysics Data System (ADS)

    Lawson, Anton E.

    Tests of formal operational reasoning derived from Piagetian theory have been found to be effective predictors of academic achievement. Yet Piaget's theory regarding the underlying nature of formal operations and their employment in specific contexts has run into considerable empirical difficulty. The primary purpose of this study was to present the core of an alternative theory of the nature of advanced scientific reasoning. That theory, referred to as the multiple-hypothesis theory, argues that tests of formal operational reasoning actually measure the extent to which persons have acquired the ability to initiate reasoning with more than one specific antecedent condition, or if they are unable to imagine more than one antecedent condition, they are aware that more than one is possible; therefore conclusions that are drawn are tempered by this possibility. As a test of this multiple-hypothesis theory of advanced reasoning and the contrasting Piagetian theory of formal operations, a sample of 922 college students were first classified as concrete operational, transitional, or formal operational, based upon responses to standard Piagetian measures of formal operational reasoning. They were then administered seven logic tasks. Actual response patterns to the tasks were analyzed and found to be similar to predicted response patterns derived from the multiple-hypothesis theory and were different from those predicted by Piagetian theory. Therefore, support was obtained for the multiple-hypothesis theory. The terms intuitive and reflective were suggested to replace the terms concrete operational and formal operational to refer to persons at varying levels of intellectual development.

  13. Relation between Hertz Stress-Life Exponent, Ball-Race Conformity, and Ball Bearing Life

    2006-01-01

    ANSI/ABMA and ISO standards based on Lundberg-Palmgren bearing life theory are normalized for ball bearings having inner- and outer-race conformities of 52 percent (0.52) and made from pre-1940 bearing steel. The Lundberg-Palmgren theory incorporates an inverse 9th power relation between Hertz stress and fatigue life for ball bearings. The effect of race conformity on ball set life independent of race life is not incorporated into the Lundberg-Palmgren theory. In addition, post-1960 vacuum-processed bearing steel exhibits a 12th power relation between Hertz stress and life. The work reported extends the previous work of Zaretsky, Poplawski, and Root to calculate changes in bearing life, that includes the life of the ball set, caused by race conformity, Hertz stress-life exponent, ball bearing type and bearing series. The bearing fatigue life in actual application will usually be equal to or greater than that calculated using the ANSI/ABMA and ISO standards that incorporate the Lundberg-Palmgren theory. The relative fatigue life of an individual race is more sensitive to changes in race conformity for Hertz stress-life exponent n of 12 than where n = 9. However, when the effects are combined to predict actual bearing life for a specified set of conditions and bearing geometry, the predicted life of the bearing will be greater for a value of n = 12 than n = 9.

The Lundberg-Palmgren theory incorporates an inverse 9th power relation between Hertz stress and fatigue life for ball bearings. The effect of race conformity on ball set life independent of race life is not incorporated into the Lundberg-Palmgren theory. In addition, post-1960 vacuum-processed bearing steel exhibits a 12th power relation between Hertz stress and life. The work reported extends the previous work of Zaretsky, Poplawski, and Root to calculate changes in bearing life--that includes the life of the ball set--caused by race conformity, Hertz stress-life exponent, ball bearing type and bearing series. The bearing fatigue life in actual application will usually be equal to or greater than that calculated using the ANSI/ABMA and ISO standards that incorporate the Lundberg-Palmgren theory. The relative fatigue life of an individual race is more sensitive to changes in race conformity for Hertz stress-life exponent n of 12 than where n = 9. However, when the effects are combined to predict actual bearing life for a specified set of conditions and bearing geometry, the predicted life of the bearing will be greater for a value of n = 12 than n = 9.

    This fictional story depicts a young Zimbabwean girl's short life amid the struggles of poverty, cultural practices, and access to health care. Through Mwatambudzeni's story, we experience her lost educational opportunities, unsuccessful fight against a system of harmful cultural practices, and her premature death caused by lack of available health care services. But it also offers a glimmer of hope as young girls, not wanting to follow in Mwatambudzeni's footsteps, begin to empower themselves through education. PMID:17990615

    Climate change mitigation demands large-scale technological change on a global level and, if successfully implemented, will significantly affect how products and services are produced and consumed. In order to anticipate the life cycle environmental impacts of products under climate mitigation scenarios, we present the modeling framework of an integrated hybrid life cycle assessment model covering nine world regions. Life cycle assessment databases and multiregional input-output tables are adapted using forecasted changes in technology and resources up to 2050 under a 2 °C scenario. We call the result of this modeling "technology hybridized environmental-economic model with integrated scenarios" (THEMIS). As a case study, we apply THEMIS in an integrated environmental assessment of concentrating solar power. Life-cycle greenhouse gas emissions for this plant range from 33 to 95 g CO2 eq./kWh across different world regions in 2010, falling to 30-87 g CO2 eq./kWh in 2050. Using regional life cycle data yields insightful results. More generally, these results also highlight the need for systematic life cycle frameworks that capture the actual consequences and feedback effects of large-scale policies in the long term.

    The purpose of the current study was to examine preservice teachers' predictions and perceptions of students with special needs' level of mastery of specific music education concepts and actual grades achieved by these students using alternative assessments and testing accommodations within two subpopulations: students with emotional and/or behavior disorders, and students with acute cognitive delays. The preservice teachers predicted students within the EDBD class would achieve a significantly higher level of mastery of the music concepts than students within the ACD classroom. After the field experience, however, the preservice teachers perceptions of all students' level of mastery increased from predictions scores overall. Additionally, pre-service teachers were able to execute testing accommodations and implement successful alternative assessments which gave empirical data on the students' level of mastery of the music education concepts within the curriculum. Finally, there was no correlation between how the preservice teachers thought students would perform, how they thought the students performed, and how the students actually performed based on assessment data.

    Five years have passed since the nuclear accident at Fukushima Daiichi Nuclear Power Stations on 11 March 2011. Here we refer to reports from international organisations as sources of predicted values obtained from environmental monitoring and dose estimation models, and reports from various institutes in Japan are used as sources of individual actual values. The World Health Organization, based on information available up to 11 September 2011 (and published in 2012), reported that characteristic effective doses in the first year after the accident, to all age groups, were estimated to be in the 10-50 mSv dose band in example locations in evacuation areas. Estimated characteristic thyroid doses to infants in Namie Town were within the 100-200 mSv dose band. A report from the United Nations Scientific Committee on the Effects of Atomic Radiation published in 2014 shows that the effective dose received by adults in evacuation areas during the first year after the accident was 1.1-13 mSv. The absorbed dose to the thyroid in evacuated settlements was 7.2-35 mSv in adults and 15-83 mSv in 1-year-old infants. Individual external radiation exposure in the initial 4 months after the accident, estimated by superimposing individual behaviour data on to a daily dose rate map, was less than 3 mSv in 93.9% of residents (maximum 15 mSv) in evacuation areas. Actual individual thyroid equivalent doses were less than 15 mSv in 98.8% of children (maximum 25 mSv) in evacuation areas. When uncertainty exists in dose estimation models, it may be sensible to err on the side of caution, and final estimated doses are often much greater than actual radiation doses. However, overestimation of the dose at the time of an accident has a great influence on the psychology of residents. More than 100 000 residents have not returned to the evacuation areas 5 years after the Fukushima accident because of the social and mental effects during the initial period of the disaster.

    Prediction of energy production is crucial to the design and installation of the building integrated photovoltaic systems. This prediction should be attainable based on the commonly available parameters such as system size, orientation and tilt angle. Several commercially available as well as free downloadable software tools exist to predict energy production. Six software models have been evaluated in this study and they are: PV Watts, PVsyst, MAUI, Clean Power Estimator, Solar Advisor Model (SAM) and RETScreen. This evaluation has been done by comparing the monthly, seasonaly and annually predicted data with the actual, field data obtained over a year period on a large number of residential PV systems ranging between 2 and 3 kWdc. All the systems are located in Arizona, within the Phoenix metropolitan area which lies at latitude 33° North, and longitude 112 West, and are all connected to the electrical grid.

    1999-10-29

    The "actual exposure" rule can now be applied in Hawaii to cases involving the recovery of damages for HIV exposure even if the virus is not transmitted. This ruling came as a result of the case of three airport baggage handlers who were exposed to a leaking container of HIV-positive blood. The Hawaii Supreme Court ruled that a plaintiff has to prove that the exposure involves a "scientifically accepted" method of transmission and that the fluid in question contained HIV. Furthermore, the court ruled, any liability for mental distress is limited to the time between discovery of contamination and confirmation that no infection resulted. With current testing standards, the time period between discovery and a negative test result is approximately 3 to 6 months.

    The Illinois Supreme Court has ruled that plaintiffs must prove actual exposure to HIV if they hope to recover damages in fear-of-AIDS lawsuits. Most state courts accept that as the standard for determining if a claim is legitimate. Two cases were addressed in the ruling. In one case, [name removed] sued Dr. [name removed] and the estate of [name removed]'s late partner, who died of AIDS-related complications in 1991. While [name removed] was employed by the doctors, she cut herself on a used scalpel in a waste basket. The scalpel was not tested, but she has had three HIV tests which have shown negative results. The other case involved six people who sued Northwestern University after learning that a dental student who treated them was HIV-positive. The six people have also tested negative.

All throws made from the first pitch to the last out for 94 half innings were videotaped from the stands. The results showed that the interrater reliability of task, environment, and performance measures were all acceptable to excellent (percentage of agreement was at least 80%), indicating that qualitative aspects of throwing can be reliably measured in an actual sport context. Alternatives to the most advanced pattern were observed at least half the time for catchers and infielders at most distances in both active and inactive situations andfor pitchers and outfielders only in inactive situations.

A fixed bed gasifier with a complete product gas cleanup system was operated in an air blown mode to produce low heating value gas. A fluidized bed gasifier with a water quench product gas cleanup system was operated in both an air enriched and an oxygen blown mode to produce low and medium, heating value gas. Noble metal catalytic reactors were evaluated in 12 cm flow diameter test rigs on both low and medium heating value gases. Combustion efficiencies greater than 99.5% were obtained with all coal derived gaseous fuels. The NOx emissions ranged from 0.2 to 4 g NO2 kg fuel.

    GSFC contractors with cost-plus contracts provide cost estimates for each of the next four quarters on a quarterly basis. Actual expenditures over a two-year period were compared to the estimates, and the data were sorted in different ways to answer several questions and give quantification to observations, such as how much does the accuracy of estimates degrade as they are made further into the future? Are estimates made for small dollar amounts more accurate than for large dollar estimates? Other government agencies and private companies with cost-plus contracts may be interested in this analysis as potential methods of contract management for their organizations. It provides them with the different methods one organization is beginning to use to control costs.

Two established measurement instruments were used to collect data from a sample of 377 allied health students. T-tests and Pearson product-moment correlations were conducted to analyze the data. Results show that allied health students take very few computer courses, but they are generally aware of the applications of computers in the practice of allied health and they desire a higher level of computer literacy than they currently have.

  16. Non-actual motion: phenomenological analysis and linguistic evidence.

    PubMed

    Blomberg, Johan; Zlatev, Jordan

    2015-09-01

    Sentences with motion verbs describing static situations have been seen as evidence that language and cognition are geared toward dynamism and change (Talmy in Toward a cognitive semantics, MIT Press, Cambridge, 2000; Langacker in Concept, image, and symbol: the cognitive basis of grammar, Mouton de Gruyter, Berlin and New York, 1990). Different concepts have been used in the literature, e.g., fictive motion, subjective motion and abstract motion to denote this. Based on phenomenological analysis, we reinterpret such concepts as reflecting different motivations for the use of such constructions (Blomberg and Zlatev in Phenom Cogn Sci 13(3):395-418, 2014). To highlight the multifaceted character of the phenomenon, we propose the concept non-actual motion (NAM), which we argue is more compatible with the situated cognition approach than explanations such as "mental simulation" (e.g., Matlock in Studies in linguistic motivation, Mouton de Gruyter, Berlin, 2004). We investigate the expression of NAM by means of a picture-based elicitation task with speakers of Swedish, French and Thai. Pictures represented figures that either afford human motion or not (±afford); crossed with this, the figure extended either across the picture from a third-person perspective (3 pp) or from a first-person perspective (1 pp). All picture types elicited NAM-sentences with the combination [+afford, 1 pp] producing most NAM-sentences in all three languages. NAM-descriptions also conformed to language-specific patterns for the expression of actual motion. We conclude that NAM shows interaction between pre-linguistic motivations and language-specific conventions.

  17. Life's timekeeper.

    PubMed

    Neill, David

    2013-03-01

    Life's timekeeper is a 'free-running' intracellular oscillator synchronised across all cells. It runs throughout life splitting lifespan into equal length phases. During the maturational period it controls the overall rate of progression whereas in the post-maturational period it controls the overall rate of ageing. This includes the rate of senescence and hence time to death. As such life's timekeeper equates maturational and post-maturational time, hence explains the tight correlation between these time periods that has existed throughout mammalian evolution. Life's timekeeper is proposed to have played an important role in vertebrate evolution. A slower oscillatory frequency results in proportional life phase prolongation. This leads to increased body and brain size, together with extended lifespan. Higher brain centres, neocortex in mammals, are disproportionately enlarged. Hence behavioural capacity is increased. The extended post-maturational period ensures that there is enough time in order that the behavioural advantages can be fully manifest in the environment. A faster oscillatory frequency would result in proportional life phase reduction. This process however would lead to reduced behavioural capacity, and is hence unlikely to be positively selected. Therefore throughout evolution life's timekeeper has operated to extend lifespan. It has hence functioned to promote longevity as opposed to ageing. PMID:23354279

    Extraterrestrial Intelligence is intelligent life that developed somewhere other than the earth. Such life has not yet been discovered. However, scientific research, including astronomy, biology, planetary science and studies of fossils here on earth have led many scientists to conclude that such life may exist on planets orbiting at least some of the hundreds of billions of stars in our Milky Way Galaxy. Today, some researchers are trying to find evidence for extraterrestrial intelligence. This effort is often called SETI, which stands for Search for Extraterrestrial Intelligence. SETI researchers decided that looking for evidence of their technology might be the best way to discover other intelligent life in the Galaxy. They decided to use large radio telescopes to search the sky over a wide range of radio frequencies...

  20. Using Artificial Life to Assess the Typicality of Terrestrial Life: Implications for Human Mission Planetary Protection

    Lupisella, Mark; Powers, Edward I. (Technical Monitor)

    2001-01-01

    The extent to which extraterrestrial life questions can be addressed, in the absence of an actual example, rests in some measure on the extent to which terrestrial life is representative of life in general since we will likely have to draw heavily, if not completely, from terrestrial life research. One example of a practical question involving extraterrestrial life that arises in preparing for a human mission to another planet such as Mars, is trying to assess and minimize the possible adverse effects of the presence of humans on possible indigenous extraterrestrial life-forms. This paper will present some key planetary protection challenges for a human Mars mission and then focus on one possible approach for assessing the extent to which terrestrial life is representative of biological phenomena in general, informing perhaps, the level of confidence we might have in applying terrestrial research - to extraterrestrial life issues. The approach involves appealing to the relatively new field of Artificial Life (A-Life) to: (1) use what might be the most basic minimal set of life-defining characteristics in (2) a large number of open-ended Artificial Life simulations to generate a "life possibility space" (3) the products of which can be examined for their plausibility within the context of relevant constraining knowledge, so that (4) the remaining possibility space can be examined for its variability relative to terrestrial life, where low variability might suggest that terrestrial life is representative of life in general, and high variability would indicate otherwise.

    2010-01-01

    Abstract Any definition is intricately connected to a theory that gives it meaning. Accordingly, this article discusses various definitions of life held in the astrobiology community by considering their connected “theories of life.” These include certain “list” definitions and a popular definition that holds that life is a “self-sustaining chemical system capable of Darwinian evolution.” We then act as “anthropologists,” studying what scientists do to determine which definition-theories of life they constructively hold as they design missions to seek non-terran life. We also look at how constructive beliefs about biosignatures change as observational data accumulate. And we consider how a definition centered on Darwinian evolution might itself be forced to change as supra-Darwinian species emerge, including in our descendents, and consider the chances of our encountering supra-Darwinian species in our exploration of the Cosmos. Last, we ask what chemical structures might support Darwinian evolution universally; these structures might be universal biosignatures. Key Words: Evolution—Life—Life detection—Biosignatures.

  3. Tutorial on Actual Space Environmental Hazards For Space Systems (Invited)

    2013-12-01

    It has become common in the space science community to conduct research on diverse physical phenomena because they are thought to contribute to space weather. However, satellites contend with only three primary environmental hazards: single event effects, vehicle charging, and total dose, and not every physical phenomenon that occurs in space contributes in substantial ways to create these hazards. One consequence of the mismatch between actual threats and all-encompassing research is the often-described gap between research and operations; another is the creation of forecasts that provide no actionable information for design engineers or spacecraft operators. An example of the latter is the physics of magnetic field emergence on the Sun; the phenomenon is relevant to the formation and launch of coronal mass ejections and is also causally related to the solar energetic particles that may get accelerated in the interplanetary shock. Unfortunately for the research community, the engineering community mitigates the space weather threat (single-event effects from heavy ions above ~50 MeV/nucleon) with a worst-case specification of the environment and not with a prediction. Worst-case definition requires data mining of past events, while predictions involve large-scale systems science from the Sun to the Earth that is compelling for scientists and their funding agencies but not actionable for design or for most operations. Differing priorities among different space-faring organizations only compounds the confusion over what science research is relevant. Solar particle impacts to human crew arise mainly from the total ionizing dose from the solar protons, so the priority for prediction in the human spaceflight community is therefore much different than in the unmanned satellite community, while both communities refer to the fundamental phenomenon as space weather. Our goal in this paper is the presentation of a brief tutorial on the primary space environmental phenomena

    It has been acknowledged that females exhibit more smiling behaviors than males, but there has been little attention to this gender difference in the courtroom. Although both male and female witnesses exhibit smiling behaviors, there has been no research examining the subsequent effect of gender and smiling on witness credibility. This study used naturalistic observation to examine smiling behaviors and credibility in actual witnesses testifying in court. Raters assessed the smiling behaviors and credibility (as measured by the Witness Credibility Scale) of 32 male and female witnesses testifying in trials in a mid-sized Southern city. "Credibility raters" rated the perceived likeability, trustworthiness, confidence, knowledge, and overall credibility of the witnesses using the Witness Credibility Scale. "Smile raters" noted smiling frequency and types, including speaking/expressive and listening/receptive smiles. Gender was found to affect perceived trustworthiness ratings, in which male witnesses were seen as more trustworthy than female witnesses. No significant differences were found in the smiling frequency for male and female witnesses. However, the presence of smiling was found to contribute to perceived likeability of a witness. Smiling female witnesses were found to be more likeable than smiling male and non-smiling female witnesses.

  6. How to actualize potential: a bioecological approach to talent development.

    PubMed

    Ceci, Stephen J; Williams-Ceci, Sterling; Williams, Wendy M

    2016-08-01

    Bioecological theory posits three interacting principles to explain developmental outcomes such as fluctuating achievement levels and changing heritability coefficients. Here, we apply the theory to the domain of talent development, by reviewing short-term and long-term cognitive interventions. We argue that macro-level analyses of cultural practices (e.g., matrilineal inheritance and property ownership) and national systems of education are consistent with the bioecological theory; when the findings from these analyses are unpacked, the engines that drive them are so-called proximal processes. This finding has implications for the design and delivery of instruction and the development of talent. We argue that talent is fostered by the same three bioecological mechanisms that explain the actualization of genetic potential. We conclude by discussing several self-descriptions and personal narratives by gifted students in which they spontaneously refer to these bioecological mechanisms in their own talent-development processes. Similar testimonials have been documented by historic talent researchers such as Benjamin Bloom, noting the importance of continual adjustments in feedback.

    Five highly experienced professional pilots performed instrument landing system approaches under simulated instrument flight conditions in a Cessna 172 airplane and in a Link-Singer GAT-1 simulator while under the influence of orally administered secobarbital (0, 100, and 200 mg). Tracking performance in two axes and airspeed control were evaluated continuously during each approach. The data from the airplane and simulator were compared. Error and RMS variability were about half as large in the simulator as in the airplane. The observed data were more strongly associated with the drug level in the simulator than in the airplane. Further, the drug-related effects were more consistent in the simulator. Improvement in performance suggestive of learning effects were seen in the simulator, but not in actual flight. It is concluded that the GAT-1 simulator is a useful and sensitive device for studies of the effects of mild stress on pilot performance, but extrapolation of simulator data to the flight environment must be approached with considerable caution.

    Corrections can be used to estimate actual wetland evapotranspiration (AET) from potential evapotranspiration (PET) as a means to define the hydrology of wetland areas. Many alternate parameterizations for correction coefficients for three PET equations are presented, covering a wide range of possible data-availability scenarios. At nine sites in the wetland Everglades of south Florida, USA, the relatively complex PET Penman equation was corrected to daily total AET with smaller standard errors than the PET simple and Priestley-Taylor equations. The simpler equations, however, required less data (and thus less funding for instrumentation), with the possibility of being corrected to AET with slightly larger, comparable, or even smaller standard errors. Air temperature generally corrected PET simple most effectively to wetland AET, while wetland stage and humidity generally corrected PET Priestley-Taylor and Penman most effectively to wetland AET. Stage was identified for PET Priestley-Taylor and Penman as the data type with the most correction ability at sites that are dry part of each year or dry part of some years. Finally, although surface water generally was readily available at each monitoring site, AET was not occurring at potential rates, as conceptually expected under well-watered conditions. Apparently, factors other than water availability, such as atmospheric and stomata resistances to vapor transport, also were limiting the PET rate. ?? 2006, The Society of Wetland Scientists.

    The predation of wildlife by domestic cats (Felis catus) is a complex problem: Cats are popular companion animals in modern society but are also acknowledged predators of birds, herpetofauna, invertebrates, and small mammals. A comprehensive understanding of this conservation issue demands an understanding of both the ecological consequence of owning a domestic cat and the attitudes of cat owners. Here, we determine whether cat owners are aware of the predatory behavior of their cats, using data collected from 86 cats in two UK villages. We examine whether the amount of prey their cat returns influences the attitudes of 45 cat owners toward the broader issue of domestic cat predation. We also contribute to the wider understanding of physiological, spatial, and behavioral drivers of prey returns among cats. We find an association between actual prey returns and owner predictions at the coarse scale of predatory/nonpredatory behavior, but no correlation between the observed and predicted prey-return rates among predatory cats. Cat owners generally disagreed with the statement that cats are harmful to wildlife, and disfavored all mitigation options apart from neutering. These attitudes were uncorrelated with the predatory behavior of their cats. Cat owners failed to perceive the magnitude of their cats’ impacts on wildlife and were not influenced by ecological information. Management options for the mitigation of cat predation appear unlikely to work if they focus on “predation awareness” campaigns or restrictions of cat freedom. PMID:26306163

    Worldwide polychlorinated biphenyls (PCBs) pollution is due to complex mixtures with high number of congeners, making the determination of total PCBs in the environment an open challenge. Because the bulk of PCBs production was made of Aroclor mixtures, this analysis is usually faced by the empirical mixture identification via visual inspection of the chromatogram. However, the identification reliability is questionable, as patterns in real samples are strongly affected by the frequent occurrence of more than one mixture. Our approach is based on the determination of a limited number of congeners chosen to enable objective criteria for Aroclor identification, summing up the advantages of congener-specific analysis with the ones of total PCBs determination. A quantitative relationship is established between congeners and any single mixture, or mixtures combination, leading to the identification of the actual contamination composition. The approach, due to its generality, allows the use of different sets of congeners and any technical mixture, including the non-Aroclor ones. The results confirm that PCB environmental pollution in northern Italy is based on Aroclor. Our methodology represents an important tool to understand the source and fate of the PCBs contamination.

    Recent debates question the extent to which adopting an educational innovation requires compromise between the innovation's original design and the adoption site's context. Through compromises, the innovation's fundamental principles may be transferred, transformed, or abandoned. This paper analyzes such compromises during the piloting of Team-Based Learning (TBL). We ask: When is the process of transferring an innovation actually a process of transformation? This study is an autoethnography of our research team's implementation process. Autoethnographies are personalized accounts where authors draw on their own experiences to extend understanding of a particular topic. To conduct this autoethnography, we used an in-depth, interactive interview with the piloting clinician educator. In the analysis of TBL's fundamental principles, some aspects of the principles transferred easily, while others were transformed. Analysis raised concerns that the transformations threatened the foundational principles of TBL. While an educational innovation's techniques may seem to be surface structures, they are realizations of deeper fundamental principles. The fundamental principles are themselves realizations of the innovation's foundational philosophy. When techniques and/or principles are modified to a context, it is important to analyze if the modifications continue to uphold the innovation's philosophy. PMID:21725841

    Numerous functions of ecosystems are essential to the quality of human life, including the provision of food, the decomposition of sewage, the provision of portable water, and the replacement of breathable air. Although attributes of ecosystems directly of use to human societies are not the only ones worth protecting, emphasizing their services may be the most effective means of communicating risks of toxicants to the general public. However, although spatial and temporal scales of experiments to assess risk vary relatively little, actual spatial scales vary considerably, from local environments to global ecosystems. Generally, models are used to bridge these gaps in scale. In this paper, we examine ways in which toxicity test endpoints have been developed to describe effects of pollutants on essential ecosystem functions and the ways in which results are then extrapolated to scales that risk managers can use.

    Ancillary services are those functions performed by electrical generating, transmission, system-control, and distribution-system equipment and people to support the basic services of generating capacity, energy supply, and power delivery. The Federal Energy Regulatory Commission defined ancillary services as ``those services necessary to support the transmission of electric power from seller to purchaser given the obligations of control areas and transmitting utilities within those control areas to maintain reliable operations of the interconnected transmission system.`` FERC identified six ancillary services reactive power and voltage control, loss compensation, scheduling and dispatch, load following, system protection, and energy imbalance. Our earlier work identified 19 ancillary services Here we offer a revised set of seven ancillary services and mention several other services that merit consideration. In preparing its final rule on open-access transmission service, we suggest that FERC consider splitting its system-protection service into its two primary pieces, reliability reserve and supplemental-operating reserve. We also suggest that FERC define more sharply all of the ancillary services. especially load-following reserve and energy imbalance. Finally, we suggest that FERC consider other services and their provision in a restructured electricity industry; these services include black-start capability, time correction, standby service. planning reserve, redispatch. transmission services, power quality, and planning and engineering services.

    The objective of the present study is to systematically evaluate and compare the rheological behaviors of body cream and body lotion in actual usage situations. Using a strain-controlled rheometer, the steady shear flow properties of commercially available body cream and body lotion were measured over a wide range of shear rates, and the linear viscoelastic properties of these two materials in small amplitude oscillatory shear flow fields were measured over a broad range of angular frequencies. The temperature dependency of the linear viscoelastic behaviors was additionally investigated over a temperature range most relevant to usual human life. The main findings obtained from this study are summarized as follows: (1) Body cream and body lotion exhibit a finite magnitude of yield stress. This feature is directly related to the primary (initial) skin feel that consumers usually experience during actual usage. (2) Body cream and body lotion exhibit a pronounced shear-thinning behavior. This feature is closely connected with the spreadability when cosmetics are applied onto the human skin. (3) The linear viscoelastic behaviors of body cream and body lotion are dominated by an elastic nature. These solid-like properties become a criterion to assess the selfstorage stability of cosmetic products. (4) A modified form of the Cox-Merz rule provides a good ability to predict the relationship between steady shear flow and dynamic viscoelastic properties for body cream and body lotion. (5) The storage modulus and loss modulus of body cream show a qualitatively similar tendency to gradually decrease with an increase in temperature. In the case of body lotion, with an increase in temperature, the storage modulus is progressively decreased while the loss modulus is slightly increased and then decreased. This information gives us a criterion to judge how the characteristics of cosmetic products are changed by the usual human environments.

  20. Establishing seasonal chronicles of actual evapotranspiration under sloping conditions

    Estimation of daily and seasonal actual evapotranspiration (ETa) is strongly needed for hydrological and agricultural purposes. Although the eddy covariance method is well suited for such estimation of land surface fluxes, this method suffers from limitations when establishing long time series. Missing data are often encountered, resulting from bad meteorological conditions, rejection by quality control tests, power failures… Numerous gap fill techniques have been proposed in the literature but there applicability in sloping conditions is not well known. In order to estimate ETa over long periods (agricultural cycle) on crops cultivated in sloping areas, a pluri-annual experiment was conducted in the Kamech catchment, located in North-eastern Tunisia. This Mediterranean site is characterized by a large heterogeneity in topography, soils and crops. Land surface fluxes were measured using eddy covariance systems. Measurements were collected on the two opposite sides of the Kamech V-shaped catchment, within small fields having slopes steeper than 5%. During three different years, four crops were studied: durum wheat, oat, fava bean and pasture. The topography of the catchment and the wind regime induced upslope and downslope flows over the study fields. In this study, we showed that gap filling of the turbulent fluxes (sensible and latent heat) can be obtained through linear regressions against net radiation. To account for the effect of the topography, linear regressions were calibrated by distinguishing upslope and downslope flows. This significantly improved the quality of the reconstructed data over 30 minute intervals. This gap filling technique also improved the energy balance closure at the daily time scale. As a result, seasonal chronicles of daily ETa throughout the growth cycle of the study crops in the Kamech watershed were established, thus providing useful information about the water use of annual crops in a semi-arid rainfed and hilly area.
